ITEM 2.       ACQUISITION AND DISPOSITION OF ASSETS

              On April 2, 1998, Omega Protein Corporation ("Omega Protein")
              completed an initial public offering of 8.5 million shares of its
              common stock for $16 per share (the "Offering") less underwriting
              discounts and selling commissions. Prior to the Offering, Omega
              Protein was a wholly-owned subsidiary of Zapata Corporation
              ("Zapata" or the "Company"). Of the 8.5 million shares of Omega
              Protein common stock sold in the Offering, Zapata sold 4.5 million
              shares and Omega Protein sold 4 million shares. Immediately
              following the Offering, Zapata owns 64.1% of the outstanding
              common stock of Omega Protein (59.7% if the underwriters'
              over-allotment options are exercised in full). (See Item 5 "Other
              Events" for a description of the underwriters' over-allotment
              options contained in the Underwriting Agreement). Following the
              Offering, the Company will continue to report Omega Protein's
              results on a consolidated basis using a minority interest
              adjustment.

ITEM 5.       OTHER EVENTS

              On April 2, 1998, Zapata and Omega Protein executed an
              Underwriting Agreement (the "Underwriting Agreement") with
              Prudential Securities Incorporated ("Prudential") and Deutsche
              Morgan Grenfell Inc., as representatives for the underwriters
              named therein, pursuant to which Zapata and Omega Protein sold,
              through an underwritten public offering, the shares described in
              Item 2. "Acquisitions and Disposition of Assets" above. The Common
              Stock was sold at a net price of $14.92 per share under Omega
              Protein's registration statement on Form S-1 (File No. 333-44967),
              which became effective on April 2, 1998, and Omega Protein's
              abbreviated registration statement on Form S-1 (File No.
              333-49321) filed pursuant to Rule 462(b), which became effective
              on April 3, 1998.

              Under the Underwriting Agreement, Zapata and Omega Protein granted
              the Underwriters over-allotment options, exercisable through May
              8, 1998, to purchase, in the aggregate, up to 1,275,000 additional
              shares of common stock, on a pro rata basis according to the
              number of shares sold by them at the first closing, at the net
              price of $14.92 per share. The Underwriters may exercise these
              options solely for the purpose of covering over-allotments
              incurred in the sale of shares in the Offering. If the
              Underwriters exercise their options in full, Zapata' ownership
              interest in Omega Protein will be further reduced to as low as
              59.7% of Omega Protein's outstanding common stock. As of the date
              of this Report, the Underwriters have not exercised these options.

              The Underwriting Agreement requires Zapata and Omega Protein to
              indemnify the Underwriters and contribute to losses arising out of
              certain liabilities, including liabilities under the Securities
              Act of 1933, as amended (the "Securities Act"). The Underwriting
              Agreement prohibits Zapata, directly or indirectly, from offering
              or selling any shares of Omega Protein's Common Stock or entering
              into similar or related transactions until April 8, 1999, without
              the prior written consent of Prudential, on behalf of the
              Underwriters. The Underwriting Agreement further provides that
              Zapata may not take any action during this period that would cause
              its net book value to decrease below the net proceeds received
              from by Zapata from the sale of its Omega Protein stock.

              On April 8, 1998, Zapata entered into several agreements with
              Omega Protein to define their post-Offering relationship. The
              following is a summary of each of these agreements:

              Separation Agreement. Zapata and Omega Protein have entered into a
              Separation Agreement, which, among other things, required Omega
              Protein to repay to Zapata $33.3 million of intercompany
              indebtedness owed by Omega Protein to Zapata contemporaneously
              with the consummation of the Offering. The Separation Agreement
              also prohibits Zapata from engaging in the harvesting of menhaden
              or the production or marketing of fish meal, fish oil or fish
              solubles anywhere in the United States for a period of five years
              from the date of the Separation Agreement. Under the Separation
              Agreement, Zapata and Omega Protein and its subsidiaries have
              agreed to indemnify each other with respect to any future losses
              that might arise from the Offering as a result of any untrue
              statement or alleged untrue statement in any Offering document or
              the omission or alleged omission to state a material fact in any
              Offering document (i) in Omega Protein's case except to the extent
              such statement was based on information provided by Zapata and
              (ii) in Zapata's case, only to the extent such loss relates to
              information supplied by Zapata.

              Sublease Agreement. Zapata and Omega Protein have entered into a
              Sublease Agreement which provides for Omega Protein to lease its
              principal corporate offices in Houston, Texas, comprising
              approximately 3,354 square feet, at an annual rent of
              approximately $36,204 and for a term that coincides with the
              remaining term of the primary lease under which Zapata occupies
              the space which expires in 2000. The Sublease also provides for
              Omega Protein to utilize certain shared office equipment for no
              additional charge.

              Registration Rights Agreement. Zapata and Omega Protein have
              entered into a Registration Rights Agreement. Under the
              Registration Rights Agreement, Omega Protein has granted Zapata
              certain rights (the "Registration Rights") with respect to the
              registration under the Securities Act of Omega Protein's common
              stock owned by Zapata immediately following the Offering (the
              "Registrable Securities"). Pursuant to the Registration Rights
              Agreement, Zapata may require Omega Protein, not more than once in
              any 365 day period commencing on the first anniversary of the
              closing of the Offering and on not more than three occasions after
              Zapata no longer owns a majority of the voting power of the
              outstanding capital stock of Omega Protein, to file a registration
              statement under the Securities Act covering the registration of
              the Registrable Securities, including in connection with an
              offering by Zapata of its securities that are exchangeable for the
              Registrable Securities (the "Demand Registration Rights").
              Zapata's Demand Registration Rights are subject to certain
              limitations, including that any such registration cover a number
              of Registrable Securities having a fair market value of at least
              $50.0 million at the time of the request for registration and that
              Omega Protein may be able to temporarily defer a Demand
              Registration to the extent it conflicts with another public
              offering of securities by Omega Protein or would require Omega
              Protein to disclose certain material non-public information.
              Zapata will also be able to require Omega Protein to include
              Registrable Securities owned by Zapata in a registration by Omega
              Protein of its securities (the "Piggyback Registration Rights"),
              subject to certain



                                        3

   4



              conditions, including the ability of the underwriters for the
              Offering to limit or exclude Registrable Securities therefrom.

              Omega Protein and Zapata will share equally the out-of-pocket fees
              and expenses of Omega Protein associated with a demand
              registration and Zapata will pay its pro rata share of
              underwriting discounts, commissions and related expenses (the
              "Selling Expenses"). Omega Protein will pay all expenses
              associated with a piggyback registration, except that Zapata will
              pay its pro rata share of the Selling Expenses. The Registration
              Rights Agreement contains certain indemnification and contribution
              provisions (i) by Zapata for the benefit of the Omega Protein and
              related persons, as well as any potential underwriter and (ii) by
              Omega Protein for the benefit of Zapata and related persons, as
              well as any potential underwriter. Zapata's Demand Registration
              Rights will terminate on the date that Zapata owns, on a fully
              converted or exercised basis with respect to such securities held
              by Zapata, Registrable Securities representing less than 10% of
              the then issued and outstanding voting stock of Omega Protein.
              Zapata's Piggyback Registration Rights will terminate at such time
              as it is able to sell all of its Registrable Securities pursuant
              to Rule 144 under the Securities Act within a three month period.
              Zapata also may transfer its Registration Rights to any transferee
              from it of Registrable Securities that represent, on a fully
              converted or exercised basis with respect to the Registrable
              Securities transferred, at least 20% of the then issued and
              outstanding voting stock of Omega Protein at the time of transfer;
              provided, however, that any such transferee will be limited to (i)
              two demand registrations if the transfer conveys less than a
              majority but more than 30% and (ii) one demand registration if the
              transfer conveys 30% or less of the then issued and outstanding
              voting stock of Omega Protein.

              Tax Indemnity Agreement. Prior to the Offering, Omega Protein was
              a member of Zapata's affiliated group and filed its tax returns on
              a consolidated basis with such group. As a result of the Offering,
              Omega Protein is no longer a member of the Zapata affiliated
              group. Zapata and Omega Protein have entered into a Tax Indemnity
              Agreement pursuant to which Zapata shall be responsible for paying
              all federal income taxes relating to taxable periods ending before
              and including the date on which Omega Protein is no longer a
              member of Zapata's affiliated group. Omega Protein shall be
              responsible for all taxes of Omega Protein with respect to taxable
              periods beginning after the date on which Omega Protein is no
              longer a member of Zapata's affiliated group. Omega Protein shall
              be entitled to any refunds (or reductions in tax liability)
              attributable to any carryback of Omega Protein's post-Offering tax
              attributes (i.e., net operating losses) realized by Omega Protein
              after it is no longer a member of Zapata's affiliated group. Any
              other refunds arising from the reduction in tax liability
              involving the Zapata affiliated group while Omega Protein was a
              member of such group, including but not limited to, taxable
              periods ending before or including such date, (with the exception
              of any refunds arising from a reduction in tax liability
              attributable to Omega Protein) shall belong to Zapata.

              Administrative Services Agreements. Zapata and Omega Protein
              entered into an Administrative Services Agreement pursuant to
              which Omega Protein will provide Zapata with administrative
              services upon reasonable request of Zapata. Zapata will pay




                                        4

   5



              Omega Protein for these services at Omega Protein's estimated cost
              of providing these services. This Agreement will continue until
              Zapata terminates it on 5 days advance written notice or Omega
              Protein terminates it after Zapata fails to cure a breach of the
              Agreement for 30 days after Omega Protein has given Zapata written
              notice of the breach.

              Each of the Underwriting Agreement, Separation Agreement,
              Administrative Services Agreement, Sublease Agreement and
              Registration Rights Agreement have been filed as exhibits to this
              report and are hereby incorporated herein. Reference is made to
              such Agreement for a more full and complete description of the
              terms and conditions therein.

(The accompanying notes are an intergral part of the Pro Forma Financial Statements.) 7 8 NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED BALANCE SHEET The following notes set forth the assumptions used in preparing the unaudited pro forma condensed consolidated balance sheet as of December 31, 1997. (1) To record Zapata's sale of 4.5 million shares of Omega Protein common stock in connection with the Offering. Proceeds to Zapata from the Offering were $66.6 million after commissions and selling expenses of $5.4 million. As a result of Zapata's sale of Omega Protein's common stock, Zapata recorded a gain of $32.6 million, net of tax effects of $18.0 million, and minority interest of $15.9 million. If the underwriters' over-allotment options are exercised, Zapata will sell up to an additional 675,000 shares of its Omega Protein common stock, which, if the maximum number of shares are sold by Zapata will result in additional net proceeds to Zapata of $10.1 million. In such event, Zapata will record an additional $5.0 million increase to its gain, net of tax effects of $2.7 million, and additional minority interest of $2.4 million. (2) To record the issuance and sale by Omega Protein of 4 million shares of Omega Protein common stock in connection with the Offering. Proceeds to Omega Protein from the Offering were $59.2 million after commissions and selling expenses of $4.9 million. As a result of Omega Protein's sale of its common stock, Zapata recorded a gain of $18.7 million, net of tax effects of $10.1 million, and minority interest of $30.3 million. If the underwriters' over-allotment options are exercised, Omega Protein will sell up to an additional 600,000 shares of common stock, which, if the maximum number of shares are sold by Omega Protein will result in additional net proceeds of $9.0 million; in such event, Zapata will record an additional $1.4 million gain, net of tax effects of $.7 million, and additional minority interest of $6.8 million. The Company also reclassified the $2.2 million deferred tax asset balance at December 31 ,1997 from investments and other assets to other liabilities to offset against the pro forma tax liability. Immediately following the Offering, Zapata will own 64.1% of the outstanding common stock of Omega Protein as of December 31, 1997. Assuming both underwriters' over-allotment options are exercised in full, Zapata would own 59.7% of Omega Protein's outstanding common stock. 8 9 ZAPATA CORPORATION UNAUDITED PRO FORMA CONDENSED CONSOLIDATED INCOME STATEMENT THREE MONTHS ENDED DECEMBER 31, 1997 (in thousands, except per share amounts)

to the execution of this Agreement, or (B) if such registration statement, as it
may have been amended, has not been declared by the Commission to be effective
under the Act, an amendment to such registration statement, including a form of

Representatives prior to the execution of this Agreement. The Company may also

         identified therein that such Term Sheet supplements;

         (B) if the Company does not rely on Rule 434 under the Act, the

         under the Act; or

         (C) if the Company does not rely on Rule 434 under the Act and if no
         prospectus is required to be filed pursuant to Rule 424(b) under the
         Act, the prospectus included in the Registration Statement;

Prospectus or any Term Sheet that is a part thereof or any amendment or
supplement to the Prospectus is filed with the Commission pursuant to Rule
424(b) (or, if the Prospectus or part thereof or such amendment or supplement is

and are validly existing as corporations in good standing under the laws of
their respective jurisdictions of incorporation and are duly qualified to
transact business as foreign corporations and are in good standing under the
laws of all other jurisdictions where the ownership or leasing of their
respective properties or the conduct of their respective businesses requires
such qualification, except where the failure to be so qualified would not

condition (financial or otherwise), management, business prospects, net worth,
or results of the operations of the Company or any of its subsidiaries

Prospectus), and no such proceedings have been threatened against the Company or
any of its subsidiaries or with respect to any of their respective properties;
and no contract or other document is required to be described in the
Registration Statement or the Prospectus or to be filed as an exhibit to the

the Underwriters by the Company pursuant to this Agreement, the compliance by
the Company with the other provisions of this Agreement, the consummation of the
other transactions herein contemplated and the compliance by the Company with
the provisions of the Intercompany Agreements do not (A) require the consent,
approval, authorization, registration or qualification of or with any
governmental authority, except such as have been obtained, such as may be
required under state securities or blue sky laws and, if the registration
statement filed with respect to the Securities (as amended) is not effective
under the Act as of the time of execution hereof, such as may be required (and
shall be obtained as provided in this Agreement) under the Act, or (B) conflict
with or result in a breach or violation of any of the terms and provisions of,
or constitute a default under, any indenture, mortgage, deed of trust, lease or
other agreement or instrument to which the Company or any of its subsidiaries is
a party or by which the Company or any of its subsidiaries or any of their
respective properties are bound, or the charter documents or by-laws of the
Company or any of its subsidiaries, or any statute or any judgment, decree,

   9


change in the condition (financial or otherwise), business prospects, net worth

subsidiaries, except as described in or contemplated by the Prospectus (or, if
the Prospectus is not in existence, the most recent Preliminary Prospectus).

         (xxii)  The Company and each of its subsidiaries are insured by 
insurers of recognized financial responsibility against such losses and risks
and in such amounts as are prudent and customary in the businesses in which they
are engaged; neither the Company nor any such subsidiary has been refused any

subsidiary has any reason to believe that it will not be able to renew its

         (xxiv)  The Company and its subsidiaries possess all certificates,
authorizations and permits issued by the appropriate federal, state or foreign
regulatory authorities necessary to conduct their respective businesses, and
neither the Company nor any such subsidiary has received any notice of
proceedings relating to the revocation or modification of any such certificate,
authorization or permit which, singly or in the aggregate, if the subject of an
unfavorable decision, ruling or finding, would result in a material adverse
change in the condition (financial or otherwise), business prospects, net worth
or results of operations of the Company and its subsidiaries, except as
described in or contemplated by the Prospectus (or, if the Prospectus is not in
existence, the most recent Preliminary Prospectus).

         (xxv)   The Company will conduct its operations in a manner that will 
not subject it to registration as an investment company under the Investment
Company Act of 1940, as amended (the "Investment Company Act"), and this
transaction will not cause the Company to become an investment company subject
to registration under such Act.

         (xxvi)  Each of the Selling Securityholder, the Company and their
respective subsidiaries has filed all foreign, federal, state and local tax
returns that are required to be filed or has requested extensions thereof

compliance with all terms and conditions of any such permit, license or
approval, except any such violation of law or regulation, failure to receive
required permits, licenses or other approvals or failure to comply with the
terms and conditions of such permits, licenses or approvals which would not,
singly or in the aggregate, result in a material adverse change in the condition
(financial or otherwise), business prospects, net worth or results of operations
of the Company and its subsidiaries, except as described in or contemplated by
the Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus).

         (xxviii) Each certificate signed by any officer of the Company and
delivered to the Representatives or counsel for the Underwriters shall be deemed
to be a representation and warranty by the Company to each Underwriter as to the
matters covered thereby.

         (xxix)   Except for the shares of capital stock of each of the
subsidiaries owned by the Company and such subsidiaries, neither the Company nor
any such subsidiary owns any shares of stock or any other equity securities of
any corporation or has any equity interest in any firm, partnership, association
or other entity, except as described in or contemplated by the Prospectus (or,
if the Prospectus is not in existence, the most recent Preliminary Prospectus).

         (xxx)    The Company and each of its subsidiaries maintain a system of
internal accounting controls sufficient to provide reasonable assurance that (A)
transactions are executed in accordance with management's general or specific
authorizations; (B) transactions are recorded as necessary to permit preparation
of financial statements in conformity with generally accepted accounting
principles and to maintain asset accountability; (C) access to assets is
permitted only in accordance with management's general or specific
authorization; and (D) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

         (xxxi)   No default exists, and no event has occurred which, with 
notice or lapse of time or both, would constitute a default in the due
performance and observance of any term, covenant or condition of any indenture,
mortgage, deed of trust, lease or other agreement or instrument to which the
Company or any of its subsidiaries is a party or by which the Company or any of
its subsidiaries or any of their respective properties is bound or may be
affected in any respect with regard to property, business or operations of the
Company and its subsidiaries, except for such defaults which would not singly,
or in the aggregate, result in a Material Adverse Effect.

         (xxxii)  The Company has not distributed and, prior to the later of (A)
the Closing Date and (B) the completion of the distribution of the Securities,
will not distribute any offering material in connection with the offering and
sale of the Securities other than the Registration Statement or any amendment or
supplement thereto, and the Preliminary Prospectus or the Prospectus and any
amendment on supplement thereto or other materials, if any permitted by the Act.

         (b) The Selling Securityholder represents and warrants to, and agrees
with, each of the several Underwriters that:


                                      -11-
   12




         (i)   The Selling Securityholder has full power (corporate and other) 
to enter into this Agreement, to sell, assign, transfer and deliver to the
Underwriters the Securities to be sold by the Selling Securityholder hereunder
in accordance with the terms of this Agreement and the full power (corporate and
other) to enter into the Intercompany Agreements; and this Agreement and the
Intercompany Agreements have been duly executed and delivered by the Selling
Securityholder and constitute the legal, valid and binding agreements of the
Selling Securityholder enforceable in accordance with their respective terms.
(except as rights to indemnification and contribution under the Intercompany
Agreements may be limited by applicable law, and except as enforcement (i) may
be limited by bankruptcy, insolvency, reorganization or other similar laws
affecting creditors' rights generally and (ii) is subject to general principles
of equity (regardless of whether such enforceability is considered in a
proceeding in equity or at law)).

         (ii)  The Selling Securityholder is the lawful owner of the Securities
to be sold by the Selling Securityholder hereunder and upon sale and delivery
of, and payment for, such Securities, as provided herein, the Selling
Securityholder will convey good and marketable title to such Securities, free
and clear of any security interests, liens, encumbrances, equities, claims or
other defects.

         (iii) The Selling Securityholder has not, directly or indirectly, (A)
taken any action designed to cause or result in, or that has constituted or
which might reasonably be expected to constitute, the stabilization or
manipulation of the price of any security of the Company to facilitate the sale
or resale of the Securities or (B) since the filing of the Registration
Statement (1) sold, bid for, purchased, or paid anyone any compensation for
soliciting purchases of, the Securities or (2) paid or agreed to pay to any
person any compensation for soliciting another to purchase any other securities
of the Company (except for the sale of Securities by the Selling Securityholder
under this Agreement).

         (iv)  To the extent that any statements or omissions are made in the
Registration Statement, any Preliminary Prospectus, the Prospectus or any
amendment or supplement thereto in reliance upon and in conformity with written
information furnished to the Company by the Selling Securityholder specifically
for use therein, such Preliminary Prospectus did, and the Registration Statement
and the Prospectus and any amendments or supplements thereto, when they become
effective or are filed with the Commission, as the case may be, will conform in
all material respects to the requirements of the Act, the Exchange Act and the
respective rules and regulations of the Commission thereunder and will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they are made, not misleading. The
Selling Securityholder has reviewed the

                                      -12-
   13




Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus) and the Registration Statement, and the information
regarding the Selling Securityholder set forth therein under the caption
"Principal and Selling Stockholder" is complete and accurate.

         (v)    The sale of the Securities by the Selling Securityholder
pursuant hereto is not prompted by any adverse information concerning the
Company that is not set forth in the Registration Statement or the Prospectus
(or, if the Prospectus is not in existence, the most recent Preliminary
Prospectus).

         (vi)   The sale of the Securities to the Underwriters by the Selling
Securityholder pursuant to this Agreement, the compliance by the Selling
Securityholder with the other provisions of this Agreement, the consummation of
the other transactions herein contemplated and the compliance by the Selling
Securityholder with the provisions of the Intercompany Agreements do not (A)
require the consent, approval, authorization, registration or qualification of
or with any governmental authority, except such as have been obtained, such as
may be required under state securities or blue sky laws and, if the registration
statement filed with respect to the Securities (as amended) is not effective
under the Act as of the time of execution hereof, such as may be required (and
shall be obtained as provided in this Agreement) under the Act, or (B) conflict
with or result in a breach or violation of any of the terms and provisions of,
or constitute a default under any indenture, mortgage, deed of trust, lease or
other agreement or instrument to which the Selling Securityholder is a party or
by which the Selling Securityholder or any of the Selling Securityholder's
properties are bound, or any statute or any judgment, decree, order, rule or
regulation of any court or other governmental authority or any arbitrator
applicable to the Selling Securityholder.

         (vii)  The Securityholder has not distributed and, prior to the later 
of (A) the Closing Date and (B) the completion of the distribution of the
Securities, will not distribute any offering material in connection with the
offering and sale of the Securities other than the Registration Statement or any
amendment thereto, and Preliminary Prospectus or the Prospectus or any amendment
or supplement thereto, or other materials, if any permitted by the Act.

         (viii) The transactions contemplated hereby will not cause the Selling
Securityholder to become an investment company subject to the registration under
the Investment Company Act.

         (ix)   Each certificate signed by any officer of the Selling
Securityholder and delivered to the Representatives or counsel for the
Underwriters shall be deemed to be


                                      -13-
   14




a representation and warranty by the Selling Securityholder to each Underwriter
as to the matters covered thereof.

         3. Purchase, Sale and Delivery of the Securities. (a) On the basis of
the representations, warranties, agreements and covenants herein contained and
subject to the terms and conditions herein set forth, the Company agrees to
issue and sell the Company Firm Securities and the Selling Securityholder agrees
to sell the Selling Securityholder Securities to the Underwriters, and each of
the Underwriters, severally and not jointly, agrees to purchase from the Company
and the Selling Securityholder, at a purchase price of $________ per share, the
number of Firm Securities set forth opposite the name of such Underwriter in
Schedule 1 hereto. The number of Firm Securities to be purchased from the
Company and the Selling Securityholder, respectively (as adjusted by the
Representatives to avoid fractions), by each of the Underwriters shall be
determined by multiplying the aggregate number of such Firm Securities to be
sold by the Company or the Selling Securityholder, as the case may be, by a
fraction, the numerator of which is the number of Firm Securities, set forth
opposite the name of such Underwriter on Schedule 1 hereto and the denominator
of which is the total number of Firm Securities set forth on Schedule 1 hereto.
One or more certificates in definitive form for the Firm Securities that the
several Underwriters have agreed to purchase hereunder, and in such denomination
or denominations and registered in such name or names as the Representatives
request upon notice to the Company and the Selling Securityholder at least 48
hours prior to the Firm Closing Date, shall be delivered by or on behalf of the
Company and the Selling Securityholder to the Representatives for the respective
accounts of the Underwriters, against payment by or on behalf of the
Underwriters of the purchase price therefor by wire transfer in same-day funds
(the "Wired Funds") to the respective accounts of the Company and the Selling
Securityholder. Such delivery of and payment for the Firm Securities shall be
made at the offices of Fulbright & Jaworski L.L.P., 666 Fifth Avenue, New York,
New York 10103 at 9:30 A.M., New York time, on __________, 1998, or at such
other place, time or date as the Representatives, the Company and the Selling
Securityholder may agree upon or as the Representatives may determine pursuant
to Section 9 hereof, such time and date of delivery against payment being herein
referred to as the "Firm Closing Date". Each of the Company and the Selling
Securityholder severally will make such certificate or certificates for the Firm
Securities available for checking and packaging by the Representatives at the
offices in New York, New York of the Company's transfer agent or registrar or of
Prudential Securities Incorporated at least 24 hours prior to the Firm Closing
Date.

         (b) For the purpose of covering any over-allotments in connection with
the distribution and sale of the Firm Securities as contemplated by the
Prospectus, the Company and the Selling Securityholder hereby grant to the
several Underwriters options to purchase, severally and not jointly, the Option
Securities in the respective


                                      -14-
   15




amounts of 600,000 shares and 300,000 shares. The purchase price to be paid for
any Option Securities shall be the same price per share as the price per share
for the Firm Securities set forth above in paragraph (a) of this Section 3. The
options granted hereby may be exercised as to all or any part of the Option
Securities from time to time within thirty (30) days after the date of the
Prospectus (or, if such 30th day shall be a Saturday or Sunday or a holiday, on
the next business day thereafter when the New York Stock Exchange is open for
trading). The Underwriters shall not be under any obligation to purchase any of
the Option Securities prior to the exercise of such options. The Representatives
may from time to time exercise the options granted hereby by giving notice in
writing or by telephone (confirmed in writing) to the Selling Securityholder
setting forth the aggregate number of Option Securities as to which the several
Underwriters are then exercising the options and the date and time for delivery
of and payment for such Option Securities. Any such date of delivery shall be
determined by the Representatives but shall not be earlier than two business
days or later than five business days after such exercise of the options and, in
any event, shall not be earlier than the Firm Closing Date. The time and date
set forth in such notice, or such other time on such other date as the
Representatives and the Selling Securityholder may agree upon or as the
Representatives may determine pursuant to Section 9 hereof, is herein called the
"Option Closing Date" with respect to such Option Securities. Upon exercise of
the options as provided herein, the Company shall become obligated to issue and
sell and the Selling Securityholder shall become obligated to sell to each of
the several Underwriters, and, subject to the terms and conditions herein set
forth, each of the Company and the Underwriters (severally and not jointly)
shall become obligated to purchase from the Selling Securityholder, the same
percentage of the total number of the Option Securities as to which the several
Underwriters are then exercising the options as such Underwriter is obligated to
purchase of the aggregate number of Firm Securities, as adjusted by the
Representatives in such manner as they deem advisable to avoid fractional
shares. Any partial exercise of the options granted hereby shall be made on a
pro rata basis in proportion to the respective maximum number of Option
Securities to be sold by each of the Company and the Selling Securityholder as
set forth herein. If the options are exercised as to all or any portion of the
Option Securities, one or more certificates in definitive form for such Option
Securities, and payment therefor, shall be delivered on the related Option
Closing Date in the manner, and upon the terms and conditions, set forth in
paragraph (a) of this Section 3, except that reference therein to the Firm
Securities and the Firm Closing Date shall be deemed, for purposes of this
paragraph (b), to refer to such Option Securities and Option Closing Date,
respectively.

         (c) Each of the Company and the Selling Securityholder hereby
acknowledges that the wire transfer by or on behalf of the Underwriters of the
purchase price for any Securities does not constitute closing of a purchase and
sale of the Securities. Only execution and delivery of a receipt for Securities
by the Underwriters indicates


                                      -15-
   16




completion of the closing of a purchase of the Securities from the Company or
the Selling Securityholder, as the case may be. Furthermore, in the event that
the Underwriters wire funds to the Company or the Selling Securityholder prior
to the completion of the closing of a purchase of Securities, each of the
Company and the Selling Securityholder hereby acknowledges that until the
Underwriters execute and deliver a receipt for the Securities, by facsimile or
otherwise, the Company or the Selling Securityholder, as the case may be, will
not be entitled to the wired funds and shall return the wired funds to the
Underwriters as soon as practicable (by wire transfer of same-day funds) upon
demand. In the event that the closing of a purchase of Securities is not
completed and the wire funds are not returned by the Company or the Selling
Securityholder, as the case may be, to the Underwriters on the same day the
wired funds were received by the Company or the Selling Securityholder, as the
case may be, each of the Company and the Selling Securityholder agrees to pay to
the Underwriters in respect of each day the wire funds are not returned by it,
in same-day funds, interest on the amount of such wire funds in an amount
representing the Underwriters' cost of financing as reasonably determined by
Prudential Securities Incorporated.

         (d) It is understood that either of you, individually and not as one of
the Representatives, may (but shall not be obligated to) make payment on behalf
of any Underwriter or Underwriters for any of the Securities to be purchased by
such Underwriter or Underwriters. No such payment shall relieve such Underwriter
or Underwriters from any of its or their obligations hereunder.

         4. Offering by the Underwriters. Upon your authorization of the release
of the Firm Securities, the several Underwriters propose to offer the Firm
Securities for sale to the public upon the terms set forth in the Prospectus.

         5. Covenants of the Company and the Selling Securityholder. (a) The
Company and the Selling Securityholder, jointly and severally, covenant and
agree with each of the Underwriters that:

         (i) The Company and the Selling Securityholder will use their best
efforts to cause the Registration Statement, if not effective at the time of
execution of this Agreement, and any amendments thereto to become effective as
promptly as possible. If required, the Company will file the Prospectus or any
Term Sheet that constitutes a part thereof and any amendment or supplement
thereto with the Commission in the manner and within the time period required by
Rules 434 and 424(b) under the Act. During any time when a prospectus relating
to the Securities is required to be delivered under the Act, the Company (A)
will comply with all requirements imposed upon it by the Act and the rules and
regulations of the Commission thereunder to the extent necessary to permit the
continuance of sales of or dealings in the Securities in


                                      -16-
   17




accordance with the provisions hereof and of the Prospectus, as then amended or
supplemented, and (B) will not file with the Commission the Prospectus, Term
Sheet or the amendment referred to in the second sentence of Section 2(a)(i)
hereof, any amendment or supplement to such Prospectus, Term Sheet or any
amendment to the Registration Statement or any Rule 462(b) Registration
Statement of which the Representatives previously have been advised and
furnished with a copy for a reasonable period of time prior to the proposed
filing and as to which filing the Representatives shall not have given their
consent. The Company will prepare and file with the Commission, in accordance
with the rules and regulations of the Commission, promptly upon request by the
Representatives or counsel for the Underwriters, any amendments to the
Registration Statement or amendments or supplements to the Prospectus that may
be necessary or advisable in connection with the distribution of the Securities
by the several Underwriters, and will use its best efforts to cause any such
amendment to the Registration Statement to be declared effective by the
Commission as promptly as possible. The Company will advise the Representatives,
promptly after receiving notice thereof, of the time when the Registration
Statement or any amendment thereto has been filed or declared effective or the
Prospectus or any amendment or supplement thereto has been filed and will
provide evidence satisfactory to the Representatives of each such filing or
effectiveness.

         (ii)  The Company will advise the Representatives, promptly after
receiving notice or obtaining knowledge thereof, of (A) the issuance by the
Commission of any stop order suspending the effectiveness of the Original
Registration Statement or any Rule 462(b) Registration Statement or any
amendment thereto or any order preventing or suspending the use of any
Preliminary Prospectus or the Prospectus or any amendment or supplement thereto,
(B) the suspension of the qualification of the Securities for offering or sale
in any jurisdiction, (C) the institution, threatening or contemplation of any
proceeding for any such purpose or (D) any request made by the Commission for
amending the Original Registration Statement or any Rule 462(b) Registration
Statement, for amending or supplementing the Prospectus or for additional
information. The Company will use its best efforts to prevent the issuance of
any such stop order and, if any such stop order is issued, to obtain the
withdrawal thereof as promptly as possible.

         (iii) The Company will cooperate with the Representatives and counsel
for the Underwriters for the qualification of the Securities for offering and
sale under (or obtain exemptions from the application of) the securities or blue
sky laws of such jurisdictions as the Representatives may designate and will
continue such qualifications in effect for as long as may be necessary to
complete the distribution of the Securities, provided, however, that in
connection therewith the Company shall not be required to qualify as a foreign
corporation, to execute a general consent to service


                                      -17-
   18




of process in any jurisdiction or take any action which would subject it to
taxation as a foreign corporation.

         (iv) If, at any time prior to the later of (A) the final date when a
prospectus relating to the Securities is required to be delivered under the Act
or (B) the Option Closing Date, any event occurs as a result of which the
Prospectus, as then amended or supplemented, would include any untrue statement
of a material fact or omit to state a material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, or if for any other reason it is necessary at any time to
amend or supplement the Prospectus to comply with the Act or the rules or
regulations of the Commission thereunder, the Company will promptly notify the
Representatives thereof and, subject to Section 5(a)(i) hereof, will prepare and
file with the Commission, at the Company's expense, an amendment to the
Registration Statement or an amendment or supplement to the Prospectus that
corrects such statement or omission or effects such compliance.

         (v)  The Company will, without charge, provide (A) to the
Representatives and to counsel for the Underwriters a signed copy of the
registration statement originally filed with respect to the Securities and each
amendment thereto (in each case including exhibits thereto) or any Rule 462(b)
Registration Statement, certified by the Secretary or an Assistant Secretary of
the Company to be true and complete copies thereof as filed with the Commission
by electronic transmission, (B) to each other Underwriter, a conformed copy of
such registration statement or any Rule 462(b) Registration Statement and each
amendment thereto (in each case without exhibits thereto) and (C) so long as a
prospectus relating to the Securities is required to be delivered under the Act,
as many copies of each Preliminary Prospectus or the Prospectus or any amendment
or supplement thereto as the Representatives may reasonably request; without
limiting the application of clause (C) of this sentence, the Company, not later
than (A) 6:00 PM, New York City time, on the date of determination of the public
offering price, if such determination occurred at or prior to 10:00 A.M., New
York City time, on such date or (B) 2:00 PM, New York City time, on the business
day following the date of determination of the public offering price, if such
determination occurred after 10:00 A.M., New York City time, on such date, will
deliver to the Underwriters, without charge, as many copies of the Prospectus
and any amendment or supplement thereto as the Representatives may reasonably
request for purposes of confirming orders that are expected to settle on the
Firm Closing Date. The Company will provide or cause to be provided to each of
the Representatives, and to each Underwriter that so requests in writing, a copy
of each report on Form SR filed by the Company as required by Rule 463 under the
Act.

         (vi) The Company, as soon as practicable, will make generally available
to its securityholders and to the Representatives a consolidated earnings
statement of the


                                      -18-
   19




Company and its subsidiaries that satisfies the provisions of Section 11(a) of
the Act and Rule 158 thereunder.

         (vii)  The Company will apply the net proceeds from the sale of the
Securities as set forth under "Use of Proceeds" in the Prospectus.

         (viii) Except pursuant to this Agreement, the Company will not,
directly or indirectly, without the prior written consent of Prudential
Securities Incorporated, on behalf of the Underwriters, offer, sell, offer to
sell, contract to sell, pledge, grant any option to purchase or otherwise sell
or dispose (or announce any offer, sale, offer of sale, contract of sale,
pledge, grant of any option to purchase or other sale or disposition) of any
shares of Common Stock or any securities convertible into, or exchangeable or
exercisable for, shares of Common Stock for a period of 180 days after the date
hereof, except pursuant to this Agreement and except for issuances pursuant to
the exercise of outstanding employee stock options and pursuant to options
granted under the Company's stock option plans and may issue shares of Common
Stock in connection with the acquisition of certain entities, but only if the
holders of such shares, options or shares issued upon exercise of such options,
agree in writing not to sell, offer, dispose of or otherwise transfer any such
shares or options during the remainder of the 180 day period without the prior
written consent of Prudential Securities Incorporated, on behalf of the
Underwriters.

         (ix)   The Company will not, directly or indirectly, (A) take any 
action designed to cause or to result in, or that has constituted or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of the
Securities or (B) (1) sell, bid for, purchase, or pay anyone any compensation
for soliciting purchases of, the Securities or (2) pay or agree to pay to any
person any compensation for soliciting another to purchase any other securities
of the Company.

         (x)    The Company will obtain the agreements described in Section 7(h)
hereof prior to the Firm Closing Date.

         (xi)   If at any time during the 25-day period after the Registration
Statement becomes effective or the period prior to the Option Closing Date, any
rumor, publication or event relating to or affecting the Company shall occur as
a result of which in your opinion the market price of the Common Stock has been

         (b)    The Selling Securityholder covenants and agrees with each of the
several Underwriters that:

         (i)    The Selling Securityholder will not, directly or indirectly, (A)
take any action designed to cause or result in, or that has constituted or which
might reasonably be expected to constitute, the stabilization or manipulation of
the price of any security of the Company to facilitate the sale or resale of the
Securities or (B) (1) sell, bid for, purchase, or pay anyone any compensation
for soliciting purchases of, the Securities or (2) pay or agree to pay to any
person any compensation for soliciting another to purchase any other securities
of the Company other than as provided by this Agreement.

         (ii)   The Selling Securityholder will not, directly or indirectly,

legally or beneficially owned by such Selling Securityholder or any securities
convertible into, or exchangeable or exercisable for, Securities for a period of
360 days after the date hereof, except pursuant to this Agreement.

         (iii)  As soon as the Selling Securityholder is advised thereof, the
Selling Securityholder will advise the Representatives (and immediately
thereafter confirm such advise in writing), (A) of receipt by the Selling
Securityholder or by any representative or agent of the Selling Securityholder,

the Prospectus or any Preliminary Prospectus, or any notice or order of the
Commission relating to the Company or the Selling Securityholder in connection
with the transactions contemplated by this


                                      -20-
   21




Agreement and (B) of the happening of any event which makes or may make any
statement of a material fact made in the Registration Statement, the Prospectus
or any Preliminary Prospectus relating to the Selling Securityholder untrue or
that requires the making of any change in the Registration Statement, Prospectus
or Preliminary Prospectus, as the case may be, in order to make such statement,
in light of the circumstances in which it was made, not misleading.

         (iv) For a period of 365 days after the date hereof, the Selling
Securityholder shall not effect a corporate dissolution or otherwise cease
operations.

         6.   Expenses. The Company will pay all costs and expenses incident to
the performance of its obligations under this Agreement, whether or not the
transactions contemplated herein are consummated or this Agreement is terminated
pursuant to Section 11 hereof, including all costs and expenses incident to (i)
the printing or other production of documents with respect to the transactions,
including any costs of printing the registration statement originally filed with
respect to the Securities and any amendment thereto, any Rule 462(b)
Registration Statement, any Preliminary Prospectus and the Prospectus and any
amendment or supplement thereto, this Agreement and any blue sky memoranda, (ii)
all arrangements relating to the delivery to the Underwriters of copies of the
foregoing documents, (iii) the fees and disbursements of the counsel, the
accountants and any other experts or advisors retained by the Company, (iv)
preparation, issuance and delivery to the Underwriters of any certificates
evidencing the Securities, including transfer agent's and registrar's fees, (v)

Underwriters), and (ix) advertising related to the offering of the Securities
(other than as shall have been specifically approved by the Representatives to
be paid for by the Underwriters). If the sale of the Securities provided for
herein is not consummated because any condition to the obligations of the
Underwriters set forth in Section 7 hereof is not satisfied, because this
Agreement is terminated pursuant to Section 11 hereof or because of any failure,
refusal or inability on the part of the Company or the Selling Securityholder to
perform all obligations and satisfy all conditions on their part to be performed
or satisfied hereunder other than by reason of a default by any of the
Underwriters, the Company will reimburse the Underwriters severally upon demand
for all out-of-pocket expenses (including counsel fees and disbursements) that
shall have been incurred by them in connection with the proposed purchase and
sale of the Securities. The Company shall not in any event be liable to any of
the Underwriters for the loss of anticipated profits from the transactions
covered


                                      -21-
   22




by this Agreement. The provisions of this Section 6 are intended to relieve the
Underwriters from payment of the costs and expenses which the Company hereby
agrees to pay and shall not affect any agreement between the Company and the
Selling Securityholder for the sharing of such costs and expenses.

         7.  Conditions of the Underwriters' Obligations. The obligations of the
several Underwriters to purchase and pay for the Firm Securities shall be
subject, in the Representatives' sole discretion, to the accuracy of the
representations and warranties of the Company and the Selling Securityholder
contained herein as of the date hereof and as of the Firm Closing Date, as if
made on and as of the Firm Closing Date, to the accuracy of the statements of
the Company's officers made pursuant to the provisions hereof, to the

time of execution hereof, the Original Registration Statement or such amendment
and, if the Company has elected to rely upon Rule 462(b), the Rule 462(b)
Registration Statement shall have been declared effective not later than the
earlier of (i) 11:00 A.M., New York time, on the date on which the amendment to
the registration statement originally filed with respect to the Securities or to
the Registration Statement, as the case may be, containing information regarding
the initial public offering price of the Securities has been filed with the
Commission and (ii) the time confirmations are sent or given as specified by
Rule 462(b)(2), or with respect to the Original Registration Statement, or such

the manner and within the time period required by Rules 434 and 424(b) under the

         their respective jurisdictions of incorporation and are duly qualified
         to transact business as foreign corporations and are in good standing
         under the laws of all other jurisdictions where the ownership or

         revolving line of credit;

                  (iv)  the Company has an authorized, issued and outstanding

         to summarize certain provisions of the capital stock of the Company,
         provide a fair summary


                                      -23-

         the consummation of the other transactions herein contemplated and the

         do not (A) require the consent, approval, authorization, registration
         or qualification of or with any governmental authority, except such as
         have been obtained and such as may be required under state securities
         or blue sky laws, or (B) conflict with or result in a breach or


                                      -24-
   25




         violation of any of the terms and provisions of, or constitute a
         default under, any indenture, mortgage, deed of trust, lease or other
         agreement or instrument, known to such counsel, to which the Company or
         any of the Subsidiaries is a party or by which the Company or any of
         the Subsidiaries or any of their respective properties are bound, or
         the charter documents or by-laws of the Company or any of the
         Subsidiaries, or any statute or any judgment, decree, order, rule or
         regulation of any court or other governmental authority or any
         arbitrator known to such counsel and applicable to the Company or
         Subsidiaries;

                  (x)   the Registration Statement is effective under the Act; 
         any required filing of the Prospectus, or any Term Sheet that
         constitutes a part thereof, pursuant to Rules 434 and 424(b) has been
         made in the manner and within the time period required by Rules 434 and
         424(b); and to the best of such counsel's knowledge, no stop order
         suspending the effectiveness of the Registration Statement or any
         amendment thereto has been issued, and no proceedings for that purpose
         have been instituted or threatened or, to the best knowledge of such
         counsel, are contemplated by the Commission; and

                  (xi)  the Registration Statement originally filed with respect
         to the Securities and each amendment thereto, any Rule 462(b)
         Registration Statement and the Prospectus (in each case, other than the
         financial statements and other financial or accounting information
         contained therein, as to which such counsel shall express no opinion)
         comply as to form in all material respects with the applicable
         requirements of the Act and the rules and regulations of the Commission
         thereunder.

                  (xii) if the Company elects to rely on Rule 434, the
         Prospectus is not "materially different", as such term is used in Rule
         434, from the prospectus included in the Registration Statement at the
         time of its effectiveness or an effective post-effective amendment
         thereto (including such information that is permitted to be omitted
         pursuant to Rule 430A).

         Such counsel shall also state that they have no reason to believe that
the Registration Statement, as of its effective date, contained any untrue
statement of a material fact or omitted to state any material fact required to
be stated therein or necessary to make the statements therein not misleading or
that the Prospectus, as of its date or the date of such opinion, included or
includes any untrue statement of a material fact or omitted or omits to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading.


                                      -25-
   26




         In rendering any such opinion, such counsel may rely, as to matters of
fact, to the extent such counsel deems proper, on certificates of responsible
officers of the Company and public officials. Such counsel may also state that
their opinions are limited in all respects to the laws of the State of New York,
the General Corporation Law of the State of Delaware, the laws of the State of
Nevada and applicable United States federal law, other than law pertaining to
the U.S. Food and Drug Administration, and that they have relied, insofar as the
laws of the State of Nevada are concerned, upon the opinion of Marshall, Hill,
Cassius and deLipkau.

         References to the Registration Statement and the Prospectus in this
paragraph 

         (b) shall include any amendment or supplement thereto at the date of
such opinion.

         (c) The Selling Securityholder shall have furnished to the
Representatives the opinion of Baker & Botts LLP, counsel for the Selling
Securityholder, dated the Closing Date, to the effect that:

             (i)  the Selling Securityholder has all requisite corporate power 
         to enter into this Agreement and the Tax Indemnity Agreement and the
         Registration Rights Agreement and to sell, transfer and deliver the
         Selling Securityholder Securities in the manner provided in this
         Agreement and to perform its obligations under this Agreement and the
         Tax Indemnity Agreement and the Registration Rights Agreement; this
         Agreement [and the Tax Indemnity Agreement and the Registration Rights
         Agreement] have been duly executed and delivered by the Selling
         Securityholder and are the legal, valid, binding and enforceable
         agreements of the Selling Securityholder, except as rights to indemnity
         and contribution may be limited by applicable law or public policy, and
         except as enforcement (i) may be limited by bankruptcy, insolvency,
         reorganization, moratorium or other similar laws relating to or
         affecting creditors' rights generally and (ii) is subject to general
         principles of equity and public policy (regardless of whether such
         enforceability is considered in a proceeding in equity or at law);

             (ii) upon the delivery by the Selling Securityholder to the several
         Underwriters of certificates for the Securities being sold hereunder by
         the Selling Securityholder against payment therefor as provided herein,
         assuming that the Underwriters have purchased such Securities in good
         faith and without "notice of an adverse claim" (within the meaning of
         Article 8 of the Uniform Commercial Code of the State of Nevada), the
         several Underwriters will acquire such Securities free and clear of any
         security interests, liens, encumbrances or other "adverse claims"
         (within the meaning of Article 8 of the Uniform Commercial Code of the
         State of Nevada);


                                      -26-
   27




             (iii) the sale of the Securities to the Underwriters by the Selling
         Securityholder pursuant to this Agreement, the compliance by the
         Selling Securityholder with the other provisions of this Agreement, the
         consummation of the other transactions herein contemplated and the
         compliance by the Selling Securityholder with the terms of the Tax
         Indemnity Agreement and the Registration Rights Agreement do not (A)
         require the consent, approval, authorization, registration or
         qualification of or with any governmental authority of the United
         States, the State of Texas, the State of New York or the State of
         Delaware, except such as have been obtained and such as may be required
         under state securities or blue sky laws, such as may be required under
         the Securities Act, the Exchange Act or any applicable state or foreign
         securities or Blue Sky laws in connection with the purchase and
         distribution of the Securities by the Underwriters and the clearance of
         such offering with the NASD (as to which we do not express an opinion)
         or such which, if not made or obtained, would not reasonably be
         expected to adversely affect the performance by the Selling
         Securityholder of its obligations under this Agreement, or (B) result
         in a breach or violation of any of the terms and provisions of, or
         constitute a default under any indenture, mortgage, deed of trust,
         lease or other agreement or instrument to which the Selling
         Securityholder is a party or by which the Selling Securityholder or any
         of the Selling Securityholder's properties are bound, other than any
         such breach or violation which would not reasonably be expected to
         adversely affect the performance by the Selling Securityholder of its
         obligations under this Agreement or (C) violate any statute (or rule or
         regulation promulgated pursuant to any such statute) of the United
         States, the State of Texas, the State of New York or the State of
         Delaware (provided that such counsel need not express any opinion with
         respect to compliance with any federal or state securities law, rule or
         regulation) or, to such counsel's knowledge, any judgment, decree or
         order of any court or other governmental authority of the United States
         or the State of Texas, the State of New York or the State of Delaware
         applicable to the Selling Securityholder, other than any such violation
         which would not reasonably be expected to adversely affect the
         performance by the Selling Securityholder of its obligations under this
         Agreement.

             In rendering such opinion, such counsel may rely, as to matters of
fact, on certificates of officers of the Company and public officials. Such
counsel may also state that their opinions are limited in all respects to the
laws of the State of Texas, the contract laws of the State of New York, the
General Corporation Law of the State of Delaware, the laws of the State of
Nevada and applicable United States federal law, and that they have relied,
insofar as the laws of the State of Nevada are concerned, upon the opinion of
Marshall, Hill, Cassius and deLipkau.

                  References to the Registration Statement and the Prospectus in
this paragraph 

         (c)      shall include any amendment or supplement thereto at the date
of such opinion.

         (d)      The Representatives shall have received an opinion, dated the 
Firm Closing Date, of Fulbright & Jaworski L.L.P., New York, New York, counsel
for the Underwriters, with respect to the issuance and sale of the Firm
Securities, the Registration Statement and the Prospectus, and such other
related matters as the Representatives may reasonably require, and the Company
shall have furnished to such counsel such documents as they may reasonably
request for the purpose of enabling them to pass upon such matters.

         (e)      The Representatives shall have received from Coopers & Lybrand
L.L.P. a letter or letters dated, respectively, the date hereof and the Firm
Closing Date, in form and substance satisfactory to the Representatives, to the
effect that:

                  (i)   they are independent accountants with respect to the
         Company and its consolidated subsidiaries within the meaning of the Act
         and the applicable rules and regulations thereunder;

                  (ii)  in their opinion, the audited consolidated financial
         statements and schedules examined by them and included in the
         Registration Statement and the Prospectus comply in form in all
         material respects with the applicable accounting requirements of the
         Act and the related published rules and regulations;

                  (iii) on the basis of a reading of the latest available
         interim unaudited consolidated financial statements of the Company and
         its consolidated subsidiaries, carrying out certain specified
         procedures (which do not constitute an examination made in accordance
         with generally accepted auditing standards) that would not necessarily
         reveal matters of significance with respect to the comments set forth
         in this paragraph (iii), a reading of the minute books of the
         stockholders, the board of directors and any committees thereof of the
         Company and each of its consolidated subsidiaries, and inquiries of
         certain officials of the Company and its consolidated subsidiaries who
         have responsibility for financial and accounting matters, nothing came
         to their attention that caused them to believe that: (A) the unaudited
         consolidated financial statements of the Company and its consolidated
         subsidiaries included in the Registration Statement and the Prospectus
         do not comply in form in all material respects with the applicable
         accounting requirements of the Act and the related published rules and
         regulations thereunder or are not in conformity with generally accepted
         accounting principles applied on a basis substantially


                                      -28-
   29




         consistent with that of the audited consolidated financial statements
         included in the Registration Statement and the Prospectus; (B) at a
         specific date not more than five days prior to the date of such letter,
         there were any changes in the capital stock or long-term debt of the
         Company and its consolidated subsidiaries or any decreases in net
         current assets or stockholders' equity of the Company and its
         consolidated subsidiaries, in each case compared with amounts shown on
         the December 31, 1997 unaudited consolidated balance sheet included in
         the Registration Statement and the Prospectus, or for the period from
         January 1, 1998 to such specified date total revenues, gross profit,
         operating income, net income and income per share of the Company and
         its consolidated subsidiaries were not at least ________% of the
         comparable amounts for the comparable period in the prior year, except
         in all instances for changes, decreases or increases set forth in such
         letter;

                  (iv) they have carried out certain specified procedures, not
         constituting an audit, with respect to certain amounts, percentages and
         financial information that are derived from the general accounting
         records of the Company and its consolidated subsidiaries and are
         included in the Registration Statement and the Prospectus under the
         captions "Prospectus Summary," "Risk Factors," "Company History and
         Recent Transactions," "Use of Proceeds," "Dividend Policy,"
         "Capitalization," "Dilution," "Selected Consolidated Financial Data,"
         "Management's Discussion and Analysis of Financial Condition and
         Results of Operations," "Business," "Management," "Certain Transactions
         and Arrangements between the Company and Zapata," "Principal and
         Selling Stockholder," and "Description of Capital Stock," and in
         Exhibit 11 to the Registration Statement, and have compared such
         amounts, percentages and financial information with such records of the
         Company and its consolidated subsidiaries and with information derived
         from such records and have found them to be in agreement, excluding any
         questions of legal interpretation; and

                  (v)  on the basis of a reading of the unaudited pro forma
         consolidated financial statements included in the Registration
         Statement and the Prospectus, carrying out certain specified procedures
         that would not necessarily reveal matters of significance with respect
         to the comments set forth in this paragraph (v), inquiries of certain
         officials of the Company and its consolidated subsidiaries who have
         responsibility for financial and accounting matters and proving the
         arithmetic accuracy of the application of the pro forma adjustments to
         the historical amounts in the unaudited pro forma consolidated
         financial statements, nothing came to their attention that caused them
         to believe that the unaudited pro forma consolidated condensed
         financial statements do not comply in form in all material respects
         with the applicable accounting requirements of


                                      -29-
   30




         Rule 11-02 of Regulation S-X or that the pro forma adjustments have not
         been properly applied to the historical amounts in the compilation of
         such statements.

         In the event that the letters referred to above set forth any such
changes, decreases or increases, it shall be a further condition to the
obligations of the Underwriters that (A) such letters shall be accompanied by a
written explanation of the Company as to the significance thereof, unless the
Representatives deem such explanation unnecessary, and (B) such changes,
decreases or increases do not, in the sole judgment of the Representatives, make
it impractical or inadvisable to proceed with the purchase and delivery of the
Securities as contemplated by the Registration Statement, as amended as of the
date hereof.

         References to the Registration Statement and the Prospectus in this
paragraph 

         (e)      with respect to either letter referred to above shall include 
any amendment or supplement thereto at the date of such letter.

         (f)      The Representatives shall have received a certificate, dated

                  (i)   the representations and warranties of the Company in 
         this Agreement are true and correct as if made on and as of the Firm
         Closing Date; the Registration Statement, as amended as of the Firm
         Closing Date, does not include any untrue statement of a material fact
         or omit to state any material fact necessary to make the statements
         therein not misleading, and the Prospectus, as amended or supplemented
         as of the Firm Closing Date, does not include any untrue statement of a
         material fact or omit to state any material fact necessary in order to

         which they were made, not misleading; and the Company has performed all
         covenants and agreements and satisfied all conditions on its part to be
         performed or satisfied at or prior to the Firm Closing Date;

                  (ii)  no stop order suspending the effectiveness of the
         Registration Statement or any amendment thereto has been issued, and no
         proceedings for that purpose have been instituted or threatened or, to
         the best of the Company's knowledge, are contemplated by the
         Commission; and

                  (iii) subsequent to the respective dates as of which
         information is given in the Registration Statement and the Prospectus,
         neither the Company nor any of its subsidiaries has sustained any
         material loss or interference with their respective businesses or
         properties from fire, flood, hurricane, accident or other calamity,
         whether or not covered by insurance, or from any labor dispute or any


                                      -30-
   31


         legal or governmental proceeding, and there has not been any material
         adverse change, or any development involving a prospective material
         adverse change, in the condition (financial or otherwise), management,
         business prospects, net worth or results of operations of the Company
         or any of its subsidiaries, except in each case as described in or
         contemplated by the Prospectus (exclusive of any amendment or
         supplement thereto).

         (g)      The Representatives shall have received a certificate from the
Selling Securityholder, signed by the Selling Securityholder, dated the Closing
Date, to the effect that:

                  (i)   the representations and warranties of the Selling
         Securityholder in this Agreement are true and correct as if made on and
         as of the Closing Date;

                  (ii)  the Registration Statement, as amended as of the Closing
         Date, does not include any untrue statement of a material fact or omit
         to state any material fact necessary to make the statements therein not
         misleading, and the Prospectus, as amended or supplemented as of the
         Closing Date, does not include any untrue statement of a material fact

         and agreements on its part to be performed or satisfied at or prior to
         the Closing Date.

         (h)      The Representatives shall have received from each person who

agreement to the effect that such person will not, directly or indirectly,
without the prior written consent of Prudential Securities Incorporated, on
behalf of the Underwriters, offer, sell, offer to sell, contract to sell,
pledge, grant any option to purchase or otherwise sell or dispose (or announce
any offer, sale, offer of sale, contract of sale, pledge, grant of an option to
purchase or other sale or disposition) of any shares of Common Stock or any
securities convertible into, or exchangeable or exercisable for, shares of
Common Stock for a period of 180 days after the date of this Agreement.

         (i)      On or before the Firm Closing Date, the Representatives and 
counsel for the Underwriters shall have received such further certificates,
documents or other information as they may have reasonably requested from the
Company.



                                      -31-
   32




         (j) Prior to the commencement of the offering of the Securities, the
Securities shall have been authorized for trading on the NYSE, subject to
official notice of issuance.

         All opinions, certificates, letters and documents delivered pursuant to
this Agreement will comply with the provisions hereof only if they are
reasonably satisfactory in all material respects to the Representatives and
counsel for the Underwriters. The Company shall furnish to the Representatives
such conformed copies of such opinions, certificates, letters and documents in
such quantities as the Representatives and counsel for the Underwriters shall
reasonably request.

         The respective obligations of the several Underwriters to purchase and
pay for any Option Securities shall be subject, in their discretion, to each of
the foregoing conditions to purchase the Firm Securities, except that all
references to the Firm Securities and the Firm Closing Date shall be deemed to
refer to such Option Securities and the related Option Closing Date,
respectively.

         8.  Indemnification and Contribution. (a) The Company and the Selling
Securityholder jointly and severally agree to indemnify and hold harmless each
Underwriter and each person, if any, who controls any Underwriter within the
meaning of Section 15 of the Act or Section 20 of the Securities Exchange Act of
1934 (the "Exchange Act"), against any losses, claims, damages or liabilities,
joint or several, to which such Underwriter or such controlling person may
become subject under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon:

             (i)   any untrue statement or alleged untrue statement made by
         the Company or the Selling Securityholder in Section 2 of this
         Agreement,

             (ii)  any untrue statement or alleged untrue statement of any
         material fact contained in (A) the Registration Statement or any
         amendment thereto, any Preliminary Prospectus or the Prospectus or any
         amendment or supplement thereto or (B) any application or other
         document, or any amendment or supplement thereto, executed by the
         Company or the Selling Securityholder or based upon written information
         furnished by or on behalf of the Company or the Selling Securityholder
         filed in any jurisdiction in order to qualify the Securities under the
         securities or blue sky laws thereof or filed with the Commission or any
         securities association or securities exchange (each an "Application"),

             (iii) the omission or alleged omission to state in the
         Registration Statement or any amendment thereto, any Preliminary
         Prospectus or the Prospectus or any amendment or supplement thereto, or
         any Application a

                                      -32-
   33




         material fact required to be stated therein or necessary to make the
         statements therein not misleading, or

                  (iv) any untrue statement or alleged untrue statement of any
         material fact provided by the Company contained in any audio or visual
         materials used in connection with the marketing of the Securities,
         including without limitation, slides, videos, films, tape recordings,

         and will reimburse, as incurred, each Underwriter and each such
controlling person for any legal or other expenses reasonably incurred by such
Underwriter or such controlling person in connection with investigating,
defending against or appearing as a third-party witness in connection with any
such loss, claim, damage, liability or action; provided, however, that the
Company and the Selling Securityholder will not be liable in any such case to
the extent that any such loss, claim, damage or liability arises out of or is
based upon any untrue statement or alleged untrue statement or omission or
alleged omission made in such registration statement or any amendment thereto,
any Preliminary Prospectus, the Prospectus or any amendment or supplement
thereto or any Application in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through the
Representatives specifically for use therein; and provided, further, that the
Company and the Selling Securityholder will not be liable to any Underwriter or
any person controlling such Underwriter with respect to any such untrue
statement or omission made in any Preliminary Prospectus that is corrected in
the Prospectus (or any amendment or supplement thereto) if the person asserting
any such loss, claim, damage or liability purchased Securities from such
Underwriter but was not sent or given a copy of the Prospectus (as amended or
supplemented) at or prior to the written confirmation of the sale of such
Securities to such person in any case where such delivery of the Prospectus (as
amended or supplemented) is required by the Act, unless such failure to deliver
the Prospectus (as amended or supplemented) was a result of noncompliance by the
Company with Section 5(a)(iv) or 5(a)(v) of this Agreement. This indemnity
agreement will be in addition to any liability which the Company and the Selling
Securityholder may otherwise have.

           The indemnifying party under this Section 8 shall not be liable for
any settlement of any proceeding effective without its written consent, but if
settled with such consent or if there be a final judgement for the plaintiff,
the indemnifying party agrees to indemnify the indemnified party against any
loss, claim, damage, liability or expense by reason of such settlement or
judgement. Neither the Company nor the Selling Securityholder will, without the
prior written consent of the Underwriter or Underwriters purchasing, in the
aggregate, more than fifty percent (50%) of the Securities, settle or compromise
or consent to the entry of any judgment in any pending or threatened claim,
action, suit or proceeding in respect of which indemnification may be sought
hereunder (whether or not any such Underwriter or any person who controls


                                      -33-
   34




any such Underwriter within the meaning of Section 15 of the Act or Section 20
of the Exchange Act is a party to such claim, action, suit or proceeding),
unless such settlement, compromise or consent includes an unconditional release
of all of the Underwriters and such controlling persons from all liability
arising out of such claim, action, suit or proceeding.

         (b) Each Underwriter will, severally and not jointly, indemnify and
hold harmless the Company, each of its directors, each of its officers who
signed the Registration Statement, the Selling Securityholder and each person,
if any, who controls the Company or the Selling Securityholder within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act against any
losses, claims, damages or liabilities to which the Company, any such director
or officer of the Company, the Selling Securityholder or any such controlling
person of the Company or the Selling Securityholder may become subject under the
Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement or any amendment thereto, any Preliminary
Prospectus or the Prospectus or any amendment or supplement thereto, or any
Application or (ii) the omission or the alleged omission to state therein a
material fact required to be stated in the Registration Statement or any
amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment
or supplement thereto, or any Application or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by any Underwriter through the Representatives
specifically for use therein; and, subject to the limitation set forth
immediately preceding this clause, will reimburse, as incurred, any legal or
other expenses reasonably incurred by the Company, any such director, officer or
controlling person or the Selling Securityholder in connection with
investigating or defending, settling, compromising or paying any such loss,
claim, damage, liability or any action in respect thereof. This indemnity
agreement will be in addition to any liability which each Underwriter may
otherwise have.

         (c) Promptly after receipt by an indemnified party under this Section 8
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise than under this
Section 8. In case any such action is brought against any indemnified party, and
it notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly


                                      -34-
   35




notified, to assume the defense thereof, with counsel satisfactory to such
indemnified party; provided, however, that if the defendants in any such action
include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be one or more
legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, the
indemnifying party shall not have the right to direct the defense of such action
on behalf of such indemnified party or parties and such indemnified party or
parties shall have the right to select separate counsel to defend such action on
behalf of such indemnified party or parties. After notice from the indemnifying
party to such indemnified party of its election so to assume the defense thereof
and approval by such indemnified party of counsel appointed to defend such
action, the indemnifying party will not be liable to such indemnified party
under this Section 8 for any legal or other expenses, other than reasonable
costs of investigation, subsequently incurred by such indemnified party in
connection with the defense thereof, unless (i) the indemnified party shall have
employed separate counsel in accordance with the proviso to the next preceding
sentence (it being understood, however, that in connection with such action the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (in addition to local counsel) in any one action or separate
but substantially similar actions in the same jurisdiction arising out of the
same general allegations or circumstances, designated by the Representatives in
the case of paragraph (a) of this Section 8, representing the indemnified
parties under such paragraph (a) who are parties to such action or actions) or
(ii) the indemnifying party does not promptly retain counsel satisfactory to the
indemnified party or (iii) the indemnifying party has authorized the employment
of counsel for the indemnified party at the expense of the indemnifying party.
After such notice from the indemnifying party to such indemnified party, the
indemnifying party will not be liable for the costs and expenses of any
settlement of such action effected by such indemnified party without the consent
of the indemnifying party.

         (d) In circumstances in which the indemnity agreement provided for in
the preceding paragraphs of this Section is unavailable or insufficient, for any
reason, to hold harmless an indemnified party in respect of any losses, claims,
damages or liabilities (or actions in respect thereof), each indemnifying party,
in order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages or liabilities (or actions in respect thereof) in such
proportion as is appropriate to reflect (i) the relative benefits received by
the indemnifying party or parties on the one hand and the indemnified party on
the other from the offering of the Securities or (ii) if the allocation provided
by the foregoing clause (i) is not permitted by applicable law, not only such
relative benefits but also the relative fault of the indemnifying party or
parties on the one hand and the indemnified party on the other in connection
with the statements or omissions or alleged statements or omissions that
resulted in such losses, claims,

                                      -35-
   36




damages or liabilities (or actions in respect thereof), as well as any other
relevant equitable considerations. The relative benefits received by the Company
and the Selling Securityholder on the one hand and the Underwriters on the other
shall be deemed to be in the same proportion as the total proceeds from the
offering (before deducting expenses) received by the Company and the Selling
Securityholder bear to the total underwriting discounts and commissions received
by the Underwriters. The relative fault of the parties shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company, the Selling Securityholder or
the Underwriters, the parties' relative intents, knowledge, access to
information and opportunity to correct or prevent such statement or omission,
and any other equitable considerations appropriate in the circumstances. The
Company, the Selling Securityholder and the Underwriters agree that it would not
be equitable if the amount of such contribution were determined by pro rata or
per capita allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation that does not take into
account the equitable considerations referred to above in this paragraph (d).
Notwithstanding any other provision of this paragraph (d), no Underwriter shall
be obligated to make contributions hereunder that in the aggregate exceed the
total public offering price of the Securities purchased by such Underwriter
under this Agreement, less the aggregate amount of any damages that such
Underwriter has otherwise been required to pay in respect of the same or any
substantially similar claim, and no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute hereunder are
several in proportion to their respective underwriting obligations and not
joint, and contributions among Underwriters shall be governed by the provisions
of the Prudential Securities Incorporated Master Agreement Among Underwriters.
For purposes of this paragraph (d), each person, if any, who controls an
Underwriter within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act shall have the same rights to contribution as such Underwriter, and
each director of the Company, each officer of the Company who signed the
Registration Statement and each person, if any, who controls the Company or the
Selling Securityholder within the meaning of Section 15 of the Act or Section 20
of the Exchange Act, shall have the same rights to contribution as the Company
or the Selling Securityholder, as the case may be.

         (e) The liability of the Selling Securityholder under this Section 9
shall not exceed the initial public offering price of the Securities sold by the
Selling Securityholder to the Underwriters.

         9. Default of Underwriters. If one or more Underwriters default in
their obligations to purchase Firm Securities or Option Securities hereunder and
the


                                      -36-
   37




aggregate number of such Securities that such defaulting Underwriter or
Underwriters agreed but failed to purchase is ten percent or less of the
aggregate number of Firm Securities or Option Securities to be purchased by all
of the Underwriters at such time hereunder, the other Underwriters may make
arrangements satisfactory to the Representatives for the purchase of such
Securities by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives), but if no such arrangements are
made by the Firm Closing Date or the related Option Closing Date, as the case
may be, the other Underwriters shall be obligated severally in proportion to
their respective commitments hereunder to purchase the Firm Securities or Option
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase. If one or more Underwriters so default with respect to an aggregate
number of Securities that is more than ten percent of the aggregate number of
Firm Securities or Option Securities, as the case may be, to be purchased by all
of the Underwriters at such time hereunder, and if arrangements satisfactory to
the Representatives are not made within 36 hours after such default for the
purchase by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives) of the Securities with respect to
which such default occurs, this Agreement will terminate without liability on
the part of any non-defaulting Underwriter or the Company other than as provided
in Section 10 hereof. In the event of any default by one or more Underwriters as
described in this Section 9, the Representatives shall have the right to
postpone the Firm Closing Date or the Option Closing Date, as the case may be,
established as provided in Section 3 hereof for not more than seven business
days in order that any necessary changes may be made in the arrangements or
documents for the purchase and delivery of the Firm Securities or Option
Securities, as the case may be. As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 9. Nothing herein shall relieve any defaulting Underwriter from
liability for its default.

         10. Survival. The respective representations, warranties, agreements,
covenants, indemnities and other statements of the Company, its officers, the
Selling Securityholder and the several Underwriters set forth in this Agreement
or made by or on behalf of them, respectively, pursuant to this Agreement shall
remain in full force and effect, regardless of (i) any investigation made by or
on behalf of the Company, any of its officers or directors, the Selling
Securityholder, any Underwriter or any controlling person referred to in Section
8 hereof and (ii) delivery of and payment for the Securities. The respective
agreements, covenants, indemnities and other statements set forth in Sections 6
and 8 hereof shall remain in full force and effect, regardless of any
termination or cancellation of this Agreement.

         11. Termination. (a) This Agreement may be terminated with respect to
the Firm Securities or any Option Securities in the sole discretion of the
Representatives


                                      -37-
   38




by notice to the Company and the Selling Securityholder given prior to the Firm
Closing Date or the related Option Closing Date, respectively, in the event that
the Company or the Selling Securityholder shall have failed, refused or been
unable to perform all obligations and satisfy all conditions on its part to be
performed or satisfied hereunder at or prior thereto or, if at or prior to the
Firm Closing Date or such Option Closing Date, respectively,

                  (i)   the Company or any of its subsidiaries shall have, in 
         the sole judgment of the Representatives, sustained any material loss
         or interference with their respective businesses or properties from
         fire, flood, hurricane, accident or other calamity, whether or not
         covered by insurance, or from any labor dispute or any legal or
         governmental proceeding or there shall have been any material adverse
         change, or any development involving a prospective material adverse
         change (including without limitation a change in management or control
         of the Company), in the condition (financial or otherwise), business
         prospects, net worth or results of operations of the Company and its
         subsidiaries, except in each case as described in or contemplated by
         the Prospectus (exclusive of any amendment or supplement thereto);

                  (ii)  trading in the Common Stock shall have been suspended by
         the Commission or the NYSE or trading in securities generally on the
         NYSE or the Nasdaq Stock Market's National Market shall have been
         suspended or minimum or maximum prices shall have been established on
         any such exchange or market system;

                  (iii) a banking moratorium shall have been declared by New
         York or United States authorities; or

         outbreak or escalation of any other insurrection or armed conflict

         material adverse change in general economic, political or financial
         conditions having an effect on the U.S. financial markets that, in the
         sole judgment of the Representatives, makes it impractical or
         inadvisable to proceed with the public offering or the delivery of the
         Securities as contemplated by the Registration Statement, as amended as
         of the date hereof.

of April __, 1998, by and between ZAPATA CORPORATION, a Delaware corporation

$.01 per share (the "Common Stock") , constituting all of the issued and
outstanding Common Stock.

         B. Zapata's Board of Directors (the "Zapata Board") has determined,
subject to its further consideration and the satisfaction of certain conditions,
to reduce its ownership of Protein to approximately 66.2% of the outstanding
Common Stock (prior to the exercise of the over-allotment options referred to
below) by means of an initial public offering by Protein of 4,000,000 shares of
Common Stock and the sale by Zapata of 4,000,000 shares of Common Stock (the
"IPO") (together with an additional 1,200,000 shares of Common Stock which shall
be subject to over-allotment options granted on an equal basis by Protein and
Zapata, respectively, to the IPO underwriters) as described in the registration
statement on Form S-1 (Registration No. 333-44967) filed by Protein with the
Securities and Exchange Commission (the "SEC") on or about January 27, 1998 (as
amended from time to time, including information deemed to be a part of such
registration statement at the time it becomes effective pursuant to SEC Rule
430A, the "Registration Statement").

         C. The parties hereto have determined that it is necessary and
desirable to set forth certain agreements and undertakings between Zapata and
Protein that will govern certain matters following the IPO.

         3.1      ASSUMPTION AND INDEMNIFICATION.

                  (a) Subject to Section 3.1(c), from and after the Closing
Date, Zapata shall indemnify, defend and hold harmless each member of the
Protein Group, each of their Representatives and each of the heirs, executors,
successors and assigns of any of the foregoing from and against all

out of or due to any untrue statement or alleged untrue statement of a material
fact contained in any Offering Document or the omission or alleged omission to
state in any of the Offering Documents a material fact required to be stated
therein or necessary to make the statements therein not misleading, but only
insofar as any such statement or omission was made with respect to (A) a matter
of historical fact relating to a member of the Zapata Group or (B) the present
or future intentions of Zapata or any member of the Zapata Group, in reliance
upon and in conformity with information furnished by Zapata in writing
specifically for use in connection with the preparation of the Offering
Documents and designated in such writing as having been so furnished.

                  (b) Subject to Section 3.1(c), from and after the Closing
Date, Protein shall indemnify, defend and hold harmless each member of the
Zapata Group, each of their Representatives and each of the heirs, executors,
successors and assigns of any of the foregoing from and against all
Indemnifiable Losses of any such member or Representative relating to, arising
out of or due to any untrue statement or alleged untrue statement of a material
fact contained in any Offering Document or the omission or alleged omission to
state in any of the Offering Documents a material fact required to be stated
therein or necessary to make the statements therein not misleading; provided
that Protein will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made with
respect to (i) a matter of historical fact relating to a member of the Zapata
Group or (ii) the present or future intentions of Zapata or any member of the
Zapata Group, in reliance upon and in conformity with information furnished by
Zapata in writing specifically for use in connection with the preparation of the
Offering Documents and designated in such writing as having been so furnished.

                  (c) If an Indemnitee realizes a Tax benefit or detriment by
reason of having incurred an Indemnifiable Loss for which such Indemnitee
receives an Indemnity Payment

                                      -5-
   6




from an Indemnifying Party or by reason of receiving an Indemnity Payment, then
such Indemnitee shall pay to such Indemnifying Party an amount equal to the Tax
benefit, or such Indemnifying Party shall pay to such Indemnitee an additional
amount equal to the Tax detriment (taking into account any Tax detriment
resulting from the receipt of such additional amounts), as the case may be. If,
in the opinion of counsel to an Indemnifying Party reasonably satisfactory in
form and substance to the affected Indemnitee, there is a substantial likelihood
that the Indemnitee will be entitled to a Tax benefit by reason of an
Indemnifiable Loss, the Indemnifying Party promptly shall notify the Indemnitee
and the Indemnitee promptly shall take any steps (including the filing of such
returns, amended returns or claims for refunds consistent with the claiming of
such Tax benefit) that, in the reasonable judgment of the Indemnifying Party,
are necessary and appropriate to obtain any such Tax benefit. If, in the opinion
of counsel to an Indemnitee reasonably satisfactory in form and substance to the
affected Indemnifying Party, there is a substantial likelihood that the
Indemnitee will be subjected to a Tax detriment by reason of an Indemnification
Payment, the Indemnitee promptly shall notify the Indemnifying Party and the
Indemnitee promptly shall take any steps (including the filing of such returns
or amended returns or the payment of Tax underpayments consistent with the
settlement of any liability for Taxes arising from such Tax detriment) that, in
the reasonable judgment of the Indemnitee, are necessary and appropriate to
settle any liabilities for Taxes arising from such Tax detriment. If, following
a payment by an Indemnitee or an Indemnifying Party pursuant to this Section
3.1(c) in respect of a Tax benefit or detriment, there is an adjustment to the
amount of such Tax benefit or detriment, then each of Zapata and Protein shall
make appropriate payments to the other, including the payment of interest
thereon at the federal statutory rate then in effect, to reflect such
adjustment. This Section 3.1(c) shall govern the matters discussed in this
Section and shall control over any conflicting language in the Tax
Indemnification Agreement.

                  (d) The amount which an Indemnifying Party is required to pay
to any Indemnitee pursuant to this Section 3.1 shall be reduced (including
retroactively) by any Insurance Proceeds and other amounts actually recovered by
such Indemnitee in reduction of the related Indemnifiable Loss. Zapata and
Protein shall use their respective best efforts to collect any Insurance
Proceeds or other amounts to which they or any of their Subsidiaries are
entitled, without regard to whether they are the Indemnifying Party hereunder.
If an Indemnitee receives an Indemnity Payment in respect of an Indemnifiable
Loss and subsequently receives Insurance Proceeds or other amounts in respect of
such Indemnifiable Loss, then such Indemnitee shall pay to such Indemnifying
Party an amount equal to the difference between (i) the sum of the amount of
such Indemnity Payment and the amount of such Insurance Proceeds or other
amounts actually received and (ii) the amount of such Indemnifiable Loss,
adjusted (at such time as appropriate adjustment can be determined) in each case
to reflect any premium adjustment attributable to such claim.

         3.2      PROCEDURE FOR INDEMNIFICATION.

                  (a) If any Indemnitee receives notice of the assertion of any
Third-Party Claim with respect to which an Indemnifying Party is obligated under
this Separation Agreement to provide indemnification, such Indemnitee shall give
such Indemnifying Party

                                      -6-
   7




notice thereof promptly after becoming aware of such Third-Party Claim;
provided, however, that the failure of any Indemnitee to give notice as provided
in this Section 3.2 shall not relieve any Indemnifying Party of its obligations
under this Article 3, except to the extent that such Indemnifying Party is
actually prejudiced by such failure to give notice. Such notice shall describe
such Third-Party Claim in reasonable detail.

                  (b) An Indemnifying Party, at such Indemnifying Party's own
expense and through counsel chosen by such Indemnifying Party (which counsel
shall be reasonably satisfactory to the Indemnitee), may elect to defend any
Third-Party Claim. If an Indemnifying Party elects to defend a Third-Party
Claim, then, within ten (10) Business Days after receiving notice of such
Third-Party Claim (or sooner, if the nature of such Third-Party Claim so
requires), such Indemnifying Party shall notify the Indemnitee of its intent to
do so, and such Indemnitee shall cooperate in the defense of such Third-Party
Claim. After notice from an Indemnifying Party to an Indemnitee of its election
to assume the defense of a Third-Party Claim, such Indemnifying Party shall not
be liable to such Indemnitee under this Article 3 for any legal or other
expenses subsequently incurred by such Indemnitee in connection with the defense
thereof; provided, however, that such Indemnitee shall have the right to employ
one law firm as counsel to represent such Indemnitee (which firm shall be
reasonably acceptable to the Indemnifying Party) if, in such Indemnitee's
reasonable judgment, either a conflict of interest between such Indemnitee and
such Indemnifying Party exists in respect of such claim or there may be defenses
available to such Indemnitee which are different from or in addition to those
available to such Indemnifying Party, and in that event (i) the reasonable fees
and expenses of such separate counsel shall be paid by such Indemnifying Party
(it being understood, however, that the Indemnifying Party shall not be liable
for the expenses of more than one separate counsel (in addition to local
counsel) with respect to any Third-Party Claim (even if against multiple
Indemnitees)) and (ii) each of such Indemnifying Party and such Indemnitee shall
have the right to conduct its own defense in respect of such claim. If an
Indemnifying Party elects not to defend against a Third-Party Claim, or fails to
notify an Indemnitee of its election as provided in this Section 3.2 within the
period of ten (10) Business Days described above, such Indemnitee may defend,
compromise and settle such Third-Party Claim; provided, however, that no such
Indemnitee may compromise or settle any such Third-Party Claim without the prior
written consent of the Indemnifying Party, which consent shall not be withheld
unreasonably. Notwithstanding the foregoing, the Indemnifying Party shall not,
without the prior written consent of the Indemnitee, (i) settle or compromise
any Third-Party Claim or consent to the entry of any judgment which does not
include as an unconditional term thereof the delivery by the claimant or
plaintiff to the Indemnitee of a written release from all liability, damage or
claims of any nature or kind in respect of such Third-Party Claim or (ii) settle
or compromise any Third-Party Claim in any manner that may adversely affect the
Indemnitee.

         3.3 REMEDIES CUMULATIVE. The remedies provided in this Article 3 shall
be cumulative and shall not preclude assertion by any Indemnitee of any other
rights or the seeking of any other remedies against any Indemnifying Party.

         3.4 EFFECT ON UNDERWRITING AGREEMENT. Notwithstanding anything to the
contrary that may be contained in the Underwriting Agreement or this Separation
Agreement: (i) the provisions of Section 3.1(a) and (b) shall govern and control
the indemnification, defense and hold harmless arrangements, and any claims or
losses arising hereunder, between the Zapata Group on the one hand and the
Protein Group on the other with respect to Indemnifiable Losses covered thereby;
and (ii) the provisions of such Underwriting Agreement shall govern and control
the indemnification, defense and hold harmless arrangements, and any claims or
losses arising thereunder, between the Protein Group and the Zapata Group on the
one hand and the IPO underwriters on the other.

                                   ARTICLE 4
                             ACCESS TO INFORMATION

         4.1 PROVISION OF CORPORATE RECORDS. Prior to or as promptly as
practicable after the Closing Date, Zapata shall use reasonable efforts to
accommodate Protein with respect to the delivery to Protein of all corporate
books and records of the Protein Group, including in each case copies of all
active agreements, active litigation files and government filings. From and
after the Closing Date, all books, records and copies so delivered shall be the
property of Protein.

         4.2 ACCESS TO INFORMATION. From and after the Closing Date, each of
Zapata and Protein shall afford to the other, and shall cause the members of
their respective Groups to so afford, reasonable access and duplicating rights
during normal business hours to all information within such party's possession
relating to such other party's businesses, assets or liabilities, insofar as
such access is reasonably required by such other party. Without limiting the
foregoing, information may be requested under this Section 4.2 for audit,
accounting, claims, litigation and Tax purposes, as well as for purposes of
fulfilling disclosure and reporting obligations, as Protein may reasonably
request and which are directly related to the Protein Business.

                                    ARTICLE 5
                             COVENANT NOT-TO-COMPETE

         Zapata hereby covenants and agrees that, for a period of five years
from the Closing Date, it will not engage in or invest in any business that
harvests and/or processes fish into fish meal, fish oil or fish solubles or
sells such products anywhere in the United States. Zapata acknowledges that any
breach or threatened breach of any of the provisions of this Article 5 cannot be
remedied solely by recovery of damages and that Protein shall be entitled to
obtain an injunction against such breach or threatened breach. Nothing herein,
however, shall be construed as prohibiting Protein from pursuing, in connection
with an injunction or otherwise, any other remedies available at law or in
equity for any such breach or threatened breach, including the recovery of money
damages. If any provision of this Article 5 is found to be unreasonably broad,
it shall nevertheless be enforceable to the extent reasonably necessary for
Protein to carry out to the fullest extent the parties' mutual intent in
entering into this


                                      -8-
   9




Agreement on this date, which intent is that the provisions of this Article will
be strictly enforced as agreed to.

                                    ARTICLE 6
                    RESTRICTIONS ON TRANSFER OF COMMON STOCK

         6.1 RESTRICTIONS ON TRANSFER. Zapata shall not assign, encumber,
pledge, sell, transfer or otherwise dispose of any shares of Common Stock
retained by it after the IPO (and any exercise of an over-allotment option by
the IPO underwriters) (or any other securities held by Zapata at any time that
are exercisable, convertible or exchangeable for Common Stock) now or hereafter
owned by it (i) to any Foreign Person or (ii) in any transaction (other than
another member of the Zapata Group who agrees to be bound by these restrictions)
unless it first provides Protein with 30 days advance written notice thereof (so
as to allow Protein sufficient time to put in place procedures to monitor the
number of outstanding shares owned by Foreign Persons and impose any appropriate
transfer restrictions).

         6.2 STOCK CERTIFICATE LEGEND. In order to effectuate the restrictions
contained in this Article 6, all certificates and instruments evidencing any
Common Stock (or other securities that are exercisable, convertible or
exchangeable for Common Stock) held by Zapata will be endorsed as follows:

                    The assignment, encumbrance, pledge, sale,
                    transfer or other disposition of the
                    securities evidenced hereby is limited and
                    restricted by the terms of a Separation
                    Agreement between the registered owner
                    hereof and the Corporation, dated April
                    __, 1998.

assigned by either party hereto without the prior written consent of the other

                                                                    EXHIBIT 10.2

                        ADMINISTRATIVE SERVICES AGREEMENT


         This ADMINISTRATIVE SERVICES AGREEMENT ("Agreement") is entered into as
of April__, 1998 by and between ZAPATA CORPORATION, a Delaware corporation
("Zapata"), and OMEGA PROTEIN CORPORATION, a Nevada corporation ("Protein").

                                R E C I T A L S:

         A. Prior to execution of this Agreement, Protein was a wholly-owned 
subsidiary of Zapata.

         B. Protein has completed on this date the issuance of new shares in an
initial public offering (the "IPO") and Zapata has sold in such IPO a portion of
the shares of Protein that it owned reducing Zapata's ownership of Protein's
outstanding common stock to approximately 66.2% of Protein's outstanding common
stock (or 62.1% of Protein's outstanding common stock if the underwriters
exercise their over-allotment options).

         C. During the last three years, Zapata relied on Protein for the
provision of certain administrative services.

         D. Zapata and Protein have agreed that, following the IPO, Protein will
continue to provide services to Zapata pursuant to the terms of this Agreement.

         NOW, THEREFORE, for and in consideration of the mutual agreements
contained herein, the parties hereby agree as follows:

         1.       SERVICES. Protein will provide the services described on 
Exhibit A to Zapata and may, in its sole discretion, provide such other services
as Zapata may request from time to time (all such services referred to herein as
the "Services"). The Services shall include those rendered to majority-owned
subsidiaries of Zapata (other than Protein), whether now existing or hereafter
becoming subsidiaries. Zapata may, upon reasonable notice to Protein, from time
to time, delete from the Services, prospectively, any category listed on Exhibit
A or thereafter added, or any reasonably determined subcategory thereof.

         2.       FEES AND EXPENSES.

                  (a) Zapata will pay Protein fees ("Fees") for the Services
provided by Protein to Zapata hereunder equal to Protein's cost of providing
such Services, as reasonably determined by Protein. Such Fees will include an
allocation of Protein's general and administrative overhead expense relating to
such Services. Protein may, but shall not be




   2



obligated to, determine such cost using the same methods employed by Protein to
allocate costs to Zapata for such Services prior to the IPO.

                  (b) Zapata will reimburse Protein for any reasonable and
necessary out-of-pocket expenses incurred in connection with the provision of
the Services, including any taxes or other governmental impositions attributable
to the provision of the Services (other than income or other similar taxes
assessed on the Fees). Protein will not have any obligation to advance funds on
behalf of Zapata.

                  (c) Protein will invoice Zapata for the Fees and expenses due
hereunder at the intervals determined by Protein from time to time. All invoices
will be due and payable within five (5) calendar days after the date of the
invoice.

         3.       INFORMATION AND RECORDS.

                  (a) Zapata will make available to Protein on a timely basis
all information which is reasonably necessary for Protein to provide the
Services.

                  (b) Protein will maintain records with respect to the Services
which are substantially similar to those maintained with respect to similar
Services provided for its own account, and will provide those records to Zapata
upon termination of this Agreement.

         4.       LIABILITY.

                  (a) Protein makes no express or implied warranty with respect 
to the Services.

                  (b) Protein will be liable to Zapata for any Loss (hereinafter
defined) suffered by Zapata during the term of this Agreement as a result of
acts or omissions of Protein or any stockholder, director, officer or employee
of Protein or any attorney, accountant, representative or agent retained by
Protein ("Associates") in connection with the Services provided only if and to
the extent that (i) the acts or omissions constitute gross negligence or willful
misconduct or willful disregard of instructions or directions provided by Zapata
as contemplated in Section 6, (ii) the acts or omissions would be covered by
Protein's insurance coverage under crime, fidelity or fiduciary insurance (if
any). In any event, except to the extent covered by Protein's crime, fidelity or
fiduciary insurance, (i) any claim for damages from Protein in connection with a
Service provided will be limited to the amount of Fees charged with respect to
the Service, and (iii) Protein will not be liable to Zapata for any incidental
or consequential damages, lost profits or opportunities, or exemplary or
punitive damages.

                      As used herein, "Loss" means any and all claims, 
liabilities, obligations, losses, deficiencies and damages or judgments of any
kind or nature whatsoever incurred by the person seeking recovery of such Loss
and arising from, asserted against, or associated with the furnishing or failure
to furnish the Services, regardless of by whom asserted and regardless


                                      - 2 -

   3



of whether or not any such loss is known or unknown, fixed or contingent or
asserted or unasserted incurred by Protein in connection with the provision of
the Services.

         5. INDEMNITY. Except as provided in Section 4(b), Zapata will indemnify
Protein and its Associates and hold Protein and its Associates harmless from any
and all Losses arising from, asserted against or associated with the provision
of Services by Protein to Zapata.

         6. AUTHORITY. In providing the Services, Protein may take such actions,
make such decisions and exercise such judgement on behalf of Zapata as Protein
may deem appropriate and necessary unless Zapata gives Protein prior written
notice that it should consult with particular officers or employees of Zapata
prior to taking such actions, making such decisions or exercising such
judgement. In matters as to which Zapata provides instructions or directions as
to matters requiring decision or the exercise of judgment, Protein shall follow
such instructions or directions.

         7. FORCE MAJEURE. Protein will not be liable to Zapata for any failure
to comply with this Agreement caused, directly or indirectly, by (a) a fire,
flood, explosion, riot, rebellion, revolution, labor trouble (whether or not due
to the fault of such Party), requirements or acts of any government authority or
agency or subdivision thereof, loss of source of supplies or other inability to
obtain materials or suppliers, or (b) any other cause, whether similar or
dissimilar to the foregoing, beyond the reasonable control of the parties
hereto.

         8. TERM. This Agreement, and Protein's obligation to provide Services
hereunder, shall continue until Zapata gives Protein five (5) days advance
written notice or upon written notice from Protein to Zapata if Zapata
materially breaches this Agreement and fails to cure such breach within thirty
(30) days after receiving written notice thereof from Protein. Any outstanding
Fees and expenses as well as Zapata's obligation to indemnify Protein shall
survive the termination of this Agreement indefinitely.

         9. NOTICES. All notices, demands, requests, or other communications
which may be or are required to be given, served, or sent by a party pursuant to
this Agreement will be in writing and will be (a) personally delivered, (b)
mailed by first class, registered or certified mail, return receipt requested,

                           Pittsford, New York  14534

         Each party may designate by notice in writing a new address or
facsimile number to which any notice may be given, served or sent. Each notice
will be deemed sufficiently given, served, sent or received when it is delivered
to the addressee, with an affidavit of personal delivery, the return receipt,
the delivery receipt or when delivery is refused by the addressee. Each notice
or other communication sent by facsimile will be deemed sufficiently given only
if a copy of the notice or communication is immediately sent by one of the
methods specified in (a), (b) or (c) above.

         10.      MISCELLANEOUS.

                  (a) This Agreement sets forth the entire agreement of the
parties with respect to the Services and supersedes all previous agreements,
understandings or negotiations with respect to the Services.

                  (b) The rights and obligations set forth in this Agreement may
be amended, modified or supplemented only by a writing signed by each party.

                  (c) A party may waive a right under this Agreement only by a
written waiver signed by the party. No failure to exercise or delay in
exercising a right under this Agreement will constitute a waiver of that right.

                  (d) If any provision of this Agreement is found invalid,
illegal or unenforceable, the provision will be ineffective only to the extent
of the invalidity, illegality or unenforceability, and the other provisions of
this Agreement will remain in full force and effect.

                  (e) A party may not assign its rights, and a Party may not
delegate its obligations, under this Agreement unless it first obtains the
written consent of the other party, which may be withheld at the other party's
discretion, provided, however, that Protein may assign its rights to any
wholly-owned subsidiary of Protein without Zapata's consent, provided that no
such assignment to a subsidiary shall relieve Protein of its obligations
hereunder.

enforced in accordance with the internal laws of the State of Delaware.

                  (h)      This Agreement may be executed in counterparts.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed on their behalf as of the date first above written.

         B. On even date herewith Protein and Zapata have entered into an
Underwriting Agreement with Prudential Incorporated and Deutsche Morgan

which contemplates that Protein and Zapata will conduct an initial public
offering in which Protein will issue 4,000,000 shares of Common Stock and Zapata
will sell 4,000,000 shares of Common Stock (the "IPO") (together with up to an
additional 1,200,000 shares of Common Stock which shall be subject to
over-allotment options granted on an equal basis by Protein and Zapata to the
IPO underwriters) reducing Zapata's ownership of Protein to approximately 66.2%
of the outstanding Common Stock (prior to the exercise of the over-allotment
options referred to below), all as more particularly described in the

         3.1 LIABILITY FOR TAXES WITH RESPECT TO TAXABLE PERIODS ENDING BEFORE

consistent with practices followed in prior years) and delivered to Protein a
separate United States federal income tax return for Protein and each Protein
Pre-Closing Affiliate for the period beginning October 1, 1997 and ending on the

Protein of the Final Return Notice. Zapata shall not withdraw any earnings or
assets of Protein or any Protein Pre-Closing Affiliates prior to the Effective
Date. If the Protein Final Returns show a net operating loss or other tax
benefit that is utilized by Zapata or any member of the Zapata Group and,
therefore, is not allocated to the entity incurring such tax benefit pursuant to
Treas. Reg. ss.1.1502-79, Zapata shall pay to Protein (or the appropriate
entity) the amount of any tax savings to be realized thereby within thirty (30)
days after receipt by Protein of the Protein Final Returns.

each member of the Consolidated Group having taxable income bears to the
consolidated taxable income of the Consolidated Group in accordance with Section
1552(a)(1) of the Code and the Regulations thereunder.

         3.5 UNUSED CARRY-FORWARD ATTRIBUTES. Zapata and Protein agree that, for
purposes of all required returns and reports with respect to Taxes, the amount
of unused tax credits under the Code attributable to Protein and each of the
Protein Pre-Closing Affiliates that may be carried forward to Taxable Periods
ending after the Effective Date shall, unless otherwise required by law or

respect to Taxable Periods beginning after the Effective Date which are
attributable to the Zapata Businesses. Protein shall pay all Taxes of Protein
and any Protein Post-Closing Affiliate and shall be entitled to receive and
retain all refunds of Taxes of Protein and any Protein Post-Closing Affiliate

shall pay) any Taxes shown to be due on a Tax Return for a Carry-Over Period
filed pursuant to Section 2.4(b) hereof by any member of the Consolidated Group
other than Protein or a Protein Pre-Closing Affiliate. Protein shall be
responsible for (and shall pay) any Taxes shown to be due on a Tax Return for a
Carry-Over Period filed by Protein and any Protein Pre-Closing Affiliate
pursuant to Section 2.4(a) hereof.

          3.8 CARRY-BACKS. Protein shall be entitled to any refund of any Tax

beginning after the Effective Date to any Taxable Period ending before or
including the Effective Date. The application of any such carry-backs by Protein
and/or any other current or former member of the Consolidated Group shall be in
accordance with the Code and the Treasury Regulations promulgated thereunder.
Notwithstanding this Section 3.9, Protein and any Protein Post-Closing Affiliate
shall have the right, in its sole discretion, to make any election, including
the election under Section 172(b)(3) of the Code, which would eliminate or limit
the carry-back of any loss or credit to any Taxable Period ending before or
including the Effective Date.

thereof to the extent the refund is attributable to Protein and any Protein
Pre-Closing Affiliate for any Taxable Period of the Consolidated Group ending

continue the arbitration with the remaining arbitrators. When used hereinafter,

appropriate and a decision of a majority of such arbitrators shall constitute a
decision by the arbitrator in the appropriate context.

              (c) Arbitration Procedures.

                  (i)  The arbitration shall be conducted under the auspices of
         the American Arbitration Association.

                  (ii) Each party within thirty (30) days after engagement of
         the arbitrator (fifteen (15) days in the case of a disagreement with
         respect to Section 4.1 through Section 4.5) shall submit to the
         arbitrator a written statement of the party's position (including where

                      (iii) The arbitrator shall base his decision on the
         following standards. In the case of a factual dispute between the
         parties, the arbitrator shall make a determination of the correct
         facts. In the case of a dispute regarding a legal issue, including the
         proper application of the Tax laws or the proper interpretation of this
         Agreement, the arbitrator shall make a determination in accordance with
         his best legal judgment. Upon making determinations with respect to all
         factual and legal issues in dispute, the arbitrator shall determine the
         amount due by one party to the other or such other matter with respect
         to the matter subject to the arbitration. Where relevant, as to each
         matter in dispute, the arbitrator shall find in favor of the party
         whose statement submitted pursuant to paragraph (ii) above proposed the
         amount closest to the amount so determined.

                      (iv) The arbitrator shall render a written decision
         stating only the result of such decision as soon as practicable. The
         arbitrator shall also orally explain the bases of such decision to both
         parties as soon as practicable. If and only if both parties request,
         the arbitrator shall state the bases of such decision in writing. Where
         relevant, as to each matter in dispute, the arbitrator's decision shall
         be in an amount equal to one of the total amounts asserted by one of
         the parties in the written statements submitted pursuant to paragraph
         (ii) above. The arbitrator shall not, and is not authorized to, render
         a decision in any other amount.

                      (v) The arbitrator's decision shall be final and binding
         on the parties. No appeal to any court is contemplated by this
         Agreement and each party, to the maximum extent permissible by law,
         waives and relinquishes all rights and entitlements to appeal such
         decision.

                      (vi) The arbitrator shall determine a fair allocation of
         the costs of the arbitration proceeding (including each party's legal
         fees) as between the parties.

                  prior to receipt of the notice requesting registration
                  pursuant to this Section 2(a) and the managing underwriter of

                  faith opinion, a registration at the time and on the terms

                  required to effect a registration pursuant to this Section
                  2(a) (a "Transactional Deferral") until the earliest of (A)

                  of the managing underwriter's written opinion referred to
                  above in this clause (i), unless the registration statement
                  for such offering has become effective and such offering has
                  commenced on or prior to such 60th day, and (C) if the
                  registration statement for such offering has become effective
                  and such offering has commenced on or prior to such 60th day,
                  the day on which the restrictions on the Holders contained in
                  Section 10 hereof lapse, provided, however, that the Company
                  shall not be permitted to delay a requested registration in
                  reliance on this clause (i) more than once in any 12-month
                  period;

                           (ii) if, while a registration request is pending
                  pursuant to this Section 2(a), the Company determines,
                  following consultation with and receiving advice from its
                  legal counsel, that the filing of a registration statement
                  would require the disclosure of material information that the
                  Company has a bona fide business purpose for preserving as
                  confidential and the disclosure of which the Company
                  determines reasonably and in good faith would have a material
                  adverse effect on the Company, the Company shall not be
                  required to effect a registration pursuant to this Section
                  2(a) until the earlier of (A) the date upon which such
                  material information is otherwise disclosed to the public or
                  ceases to be material and (B) 90 days after the Company makes
                  such determination;

                           (iii) the Company shall not be obligated to file a
                  registration statement relating to a registration request
                  pursuant to this Section 2: (A) prior to the first anniversary
                  of the closing of the Public Offering, (B) within a period of
                  365 calendar days after the effective date of any other
                  registration statement of the Company demanded pursuant to
                  this Section 2(a), or (C) if such registration request is for
                  a number of Registrable Securities having a Fair Market Value
                  on the business day immediately preceding the date of such
                  registration request of less than $50,000,000.00; and

                           (iv) the Company shall not be obligated to file a
                  registration statement relating to a registration request
                  pursuant to this Section 2: (A) in the case of a registration
                  request by Zapata or any Permitted Transferee that has
                  acquired, in the transaction in which it became a Permitted
                  Transferee, at least a majority of the then issued and
                  outstanding Voting Stock, on more than three occasions after
                  such time as Zapata or such Permitted Transferee, as the case
                  may be, owns less than a majority of the voting power of the
                  outstanding capital stock of the Company (it being
                  acknowledged that so long as Zapata or such Permitted
                  Transferee owns a majority of the voting power of the
                  outstanding capital stock of the Company, there shall be no
                  limit to the number of occasions on which Zapata or such
                  Permitted Transferee may exercise such rights in accordance
                  with, and subject to, the other provisions hereof), or (B) in
                  the case of a Holder other than Zapata or a Permitted
                  Transferee described in clause (A) above, on more than the
                  number of occasions permitted such Holder in accordance with
                  Section 11 hereof.

                  (b) Notwithstanding any other provision of this Agreement to
the contrary:

                           (i) a registration requested by a Holder pursuant to
                  this Section 2 shall not be deemed to have been effected (and,
                  therefore, not requested for purposes of Section 2(a)), (A)
                  unless the registration statement filed in connection
                  therewith has become effective, (B) if after such registration
                  statement has become effective, it becomes subject to any stop
                  order, or there is issued an injunction or other order or
                  decree of the SEC or other governmental agency or court for
                  any reason other than a misrepresentation or

                                      -5-
   6




                  an omission by such Holder, which injunction, order or decree
                  prohibits or otherwise materially and adversely affects the
                  offer and sale of the Registrable Securities so registered
                  prior to the completion of the distribution thereof in
                  accordance with the plan of distribution set forth in the
                  registration statement or (C) if the conditions to closing
                  specified in the purchase agreement or underwriting agreement
                  entered into in connection with such registration are not
                  satisfied by reason of some act, misrepresentation or omission
                  by the Company and are not waived by the purchasers or
                  underwriters; and

                           (ii) nothing herein shall modify a Holder's
                  obligation to pay Registration Expenses, in accordance with
                  Section 4 hereof, that are incurred in connection with any
                  withdrawn registration requested by such Holder.

                  (c) In the event that any registration pursuant to this
Section 2 shall involve, in whole or in part, an underwritten offering, Holders
owning at least 50.1% of the Fair Market Value of the Registrable Securities to
be registered in connection with such offering shall have the right to designate
an underwriter reasonably satisfactory to the Company as the lead managing
underwriter of such underwritten offering, and the Company shall have the right
to designate one underwriter reasonably satisfactory to such Holders as a
co-manager of such underwritten offering.

                  (d) The Company shall have the right to cause the registration
of additional securities for sale for the account of any person (including the
Company) in any registration of Registrable Securities requested by any Holder
pursuant to Section 2(a) only to the extent the managing underwriter or other
independent marketing agent for such offering (if any) determines that, in its
opinion, the additional securities proposed to be sold will not materially and
adversely affect the offering and sale of the Registrable Securities to be
registered in accordance with the intended method or methods of disposition then
contemplated by such Holder. The rights of a Holder to cause the registration of
additional Registrable Securities held by such Holder in any registration of
Registrable Securities requested by another Holder pursuant to Section 2(a)
shall be governed by the agreement of the Holders with respect thereto as
provided in Section 11(a).

                  (e) The Company shall not be obligated to file a registration
statement relating to a registration request by a Holder pursuant to this
Section 2 from and after such time as such Holder first owns Registrable
Securities representing (assuming for this purpose the conversion, exchange or
exercise of all Registrable Securities then owned by such Holder that are
convertible into or exercisable or exchangeable for Voting Stock of the Company)
less than 10% of the then issued and outstanding Voting Stock of the Company.

         3. Piggyback Registration. If the Company at any time proposes to
register any of its Common Stock or any other of its securities (collectively,
"Other Securities") under the Securities Act, whether or not for sale for its
own account, in a manner which would permit registration of Registrable
Securities for sale for cash to the public under the Securities Act, it will at
such time give prompt written notice to each Holder of its intention to do so at
least

                                      -6-
   7




10 business days prior to the anticipated filing date of the registration
statement relating to such registration. Such notice shall offer each such
Holder the opportunity to include in such registration statement such number of
Registrable Securities as each such Holder may request. Upon the written request
of any such Holder made within 5 business days after the receipt of the
Company's notice (which request shall specify the number of Registrable
Securities intended to be disposed of and the intended method of disposition
thereof), the Company shall effect, in the manner set forth in Section 5, in
connection with the registration of the Other Securities, the registration under
the Securities Act of all Registrable Securities which the Company has been so
requested to register, to the extent required to permit the disposition (in
accordance with such intended methods thereof) of the Registrable Securities so
requested to be registered, provided that:

                  (a) if at any time after giving written notice of its
intention to register any securities and prior to the effective date of such
registration, the Company shall determine for any reason not to register or to
delay registration of such securities, the Company may, at its election, give
written notice of such determination to the Holders and, thereupon, (A) in the
case of a determination not to register, the Company shall be relieved of its
obligation to register any Registrable Securities in connection with such
registration and (B) in the case of a determination to delay such registration,
the Company shall be permitted to delay registration of any Registrable
Securities requested to be included in such registration for the same period as
the delay in registering such other securities, but, in either such case,
without prejudice to the rights of the Holders under Section 2;

                  (b) (i) if the registration referred to in the first sentence
of this Section 3 is to be a registration in connection with an underwritten
offering on behalf of either the Company or holders of securities (other than
Registrable Securities) of the Company ("Other Holders"), and the managing
underwriter for such offering advises the Company in writing that, in such
firm's opinion, such offering would be materially and adversely affected by the
inclusion therein of Registrable Securities requested to be included therein
because such Registrable Securities are not of the same type, class or series as
the securities to be offered and sold in such offering on behalf of the Company
and/or the Other Holders, the Company may exclude all such Registrable
Securities from such offering provided that the Holder is permitted to
substitute for the Registrable Securities so excluded an equal number of
Registrable Securities of the same type, class or series as those being
registered by the Company or the Other Holders, if and to the extent such Holder
owns Registrable Securities of such type, class or series or can acquire
Registrable Securities of such type, class or series upon exercise or conversion
of other Registrable Securities; and

         (ii) if the registration referred to in the first sentence of this
Section 3 is to be a registration in connection with an underwritten primary
offering on behalf of the Company, and the managing underwriter for such
offering advises the Company in writing that, in such firm's opinion, such
offering would be materially and adversely affected by the inclusion therein of
the Registrable Securities requested to be included therein because the number
or principal amount of such Registrable Securities, considered together with the
number or principal amount of securities proposed to be offered by the Company,
exceeds the aggregate

                                      -7-
   8




number or principal amount of securities which, in such firm's opinion, can be
sold in such offering without materially and adversely affecting the offering,
the Company shall include in such registration: (1) first, all securities the
Company proposes to sell for its own account ("Company Securities") and (2)
second, the number or principal amount of Registrable Securities and securities,
if any, requested to be included therein by Other Holders in excess of the
number or principal amount of Company Securities which, in the opinion of such
underwriter, can be so sold without materially and adversely affecting such
offering (allocated pro rata among the Holders and the Other Holders on the
basis of the number of securities (including Registrable Securities) requested
to be included therein by each Holder and each such Other Holder); and

         (iii) if the registration referred to in the first sentence of this
Section 3 is to be a registration in connection with an underwritten secondary
offering on behalf of Other Holders made pursuant to demand registration rights
granted by the Company to such Other Holders (the "Initiating Holders"), and the
managing underwriter for such offering advises the Company in writing that, in
such firm's opinion, such offering would be materially and adversely affected by
the inclusion therein of the Registrable Securities requested to be included
therein because the number or principal amount of such Registrable Securities,
considered together with the number or principal amount of securities proposed
to be offered by the Initiating Holders, exceeds the aggregate number or
principal amount of securities which, in such firm's opinion, can be sold in
such offering without materially and adversely affecting the offering, the
Company shall include in such registration; (1) first, to the extent the
registration rights granted to an Initiating Holder permit it to exclude other
securities from its registration on substantially the same basis as that set
forth in the first sentence of Section 2(d) hereof, all securities any such
Initiating Holder proposes to sell for its own account, and (2) second, the
number or principal amount of additional securities (including Registrable
Securities) that such managing underwriter advises can be sold without
materially and adversely affecting such offering, allocated pro rata among any
Other Holders to which clause (1) does not apply and the Holders on the basis of
the number of securities (including Registrable Securities) requested to be
included therein by each Holder and each such Other Holder,

                  (c) the Company shall not be required to effect any
registration of Registrable Securities under this Section 3 incidental to the
registration of any of its securities in connection with stock option or other
executive or employee benefit or compensation plans of the Company;

                  (d) no registration of Registrable Securities effected under
this Section 3 shall relieve the Company of its obligation to effect any
registration of Registrable Securities required of the Company pursuant to
Section 2 hereof, except as expressly provided in Section 2(a)(iv) to the extent
such registration under this Section 3 results in a reduction in ownership below
the majority threshold specified therein; and

                  (e) the Company shall not be required to effect any
registration of Registrable Securities under this Section for any Holder from
and after such time as such Holder is able to dispose of all of its Registrable
Securities within a three-month period pursuant to Rule 144.

                                      -8-
   9





         4. Expenses. The Holders, on the one hand, by accepting Registrable
Securities, and the Company, on the other hand, each agree to pay one-half of
all Registration Expenses with respect to a registration pursuant to Section 2
hereof, provided that to the extent a registration pursuant to Section 2
includes the registration of shares for the Company or another person in
connection therewith, the Company or such other person shall pay all incremental
expenses of including such additional shares in the registration. The Holders'
portion of any Registration Expenses shall be allocated among them pro rata
based on each Holder's number or principal amount of Registrable Securities
included in such offering. The Company agrees to pay all Registration Expenses
with respect to a registration pursuant to Section 3 hereof. All Registration
Expenses to be paid by the Holder shall be paid within 10 days of the delivery
of a statement from the Company, such statements to be delivered not more
frequently than once every 30 days. All internal expenses of the Company or a
Holder in connection with any offering pursuant to this Agreement, including,
without limitation, the salaries and expenses of officers and employees,
including in-house attorneys, shall be borne by the party incurring them. All
Selling Expenses of the Holders participating in any registration pursuant to
this Agreement shall be borne by such Holders pro rata based on each Holder's
number of Registrable Securities included in such registration.

         5. Registration and Qualification. If and whenever the Company is
required to use its best efforts to effect the registration of any Registrable
Securities under the Securities Act as provided in Section 2 or 3 hereof, the
Company, subject to Section 4 hereof, shall:

                  (a) prepare and file a registration statement under the
Securities Act relating to the Registrable Securities to be offered as soon as
practicable, but in no event later than 45 days (60 days if the applicable
registration form is other than Form S-3) after the date notice is given, and
use its best efforts to cause the same to become effective within 90 days after
the date notice is given (120 days if the applicable registration form is other
than Form S-3);

                  (b) prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective with
respect to the disposition of all Registrable Securities until the earlier of
(i) such time as all of such Registrable Securities have been disposed of in
accordance with the intended methods of disposition set forth in such
registration statement and (ii) the expiration of nine months after such
registration statement becomes effective; provided, that such nine-month period
shall be extended for such number of days that equals the number of days
elapsing from (A) the date the written notice contemplated by paragraph (f)
below is given by the Company to (B) the date on which the Company delivers to
the Holders of Registrable Securities the supplement or amendment contemplated
by paragraph (f) below; and provided further, that in the case of a registration
to permit the exercise or exchange of Exchangeable Securities for, or the
conversion of Exchangeable Securities into, Registrable Securities, the time
limitation contained in clause (ii) above shall be disregarded to the extent
that, in the written opinion of Zapata's counsel delivered to the Company, such
Registrable Securities are required to be covered by an effective registration
statement under the Securities Act at the time such Registrable Securities
are issued upon exercise, exchange or conversion of Registrable Securities in
order for such 

                                      -9-
   10




Registrable Securities to be freely tradeable by any person who is not an
Affiliate of the Company or Zapata;

                  (c) furnish to the Holders and to any underwriter of such
Registrable Securities such number of conformed copies of such registration
statement and of each such amendment and supplement thereto (in each case
including all exhibits), such number of copies of the prospectus included in
such registration statement (including each preliminary prospectus and any
summary prospectus), in conformity with the requirements of the Securities Act,
and such other documents, as the Holders or such underwriter may reasonably
request in order to facilitate the public sale of the Registrable Securities,
and a copy of any and all transmittal letters or other correspondence to, or
received from, the SEC or any other governmental agency or self-regulatory body
or other body having jurisdiction (including any domestic or foreign securities
exchange) relating to such offering;

                  (d) use its best efforts to register or qualify all
Registrable Securities covered by such registration statement under the
securities or blue sky laws of such jurisdictions (domestic or foreign) as the
Holders or any underwriter of such Registrable Securities shall request, and use
its best efforts to obtain all appropriate registrations, permits and consents
required in connection therewith, and do any and all other acts and things which
may be necessary or advisable to enable the Holders or any such underwriter to
consummate the disposition in such jurisdictions of its Registrable Securities
covered by such registration statement; provided that the Company shall not for
any such purpose be required to register or qualify generally to do business as
a foreign corporation in any jurisdiction wherein it is not so qualified, or to
subject itself to taxation in any such jurisdiction, or to consent to general
service of process in any such jurisdiction;

                  (e) (i) use its best efforts to furnish an opinion of counsel
for the Company addressed to the underwriters and each Holder of Registrable
Securities included in such registration (each a "Selling Holder") and dated the
date of the closing under the underwriting agreement (if any) (or if such
offering is not underwritten, dated the effective date of the registration
statement), and (ii) use its best efforts to furnish a "cold comfort" letter
addressed to each Selling Holder, if permissible under applicable accounting
practices, and signed by the independent public accountants who have audited the
Company's financial statements included in such registration statement, in each
such case covering substantially the same matters with respect to such
registration statement (and the prospectus included therein) as are customarily
covered in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities and, in the case of
such accountants' letter, with respect to events subsequent to the date of such
financial statements;

                  (f) immediately notify each Selling Holder in writing (i) at
any time when a prospectus relating to a registration pursuant to Section 2 or 3
hereof is required to be delivered under the Securities Act of the happening of
any event as a result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were


                                      -10-
   11

made, not misleading, and (ii) if any request by the SEC or any other regulatory
body or other body having jurisdiction for any amendment of or supplement to any
registration statement or other document relating to such offering, and in
either such case (i) or (ii) at the request of the Selling Holders, subject to
Section 4 hereof, prepare and furnish to the Selling Holders a reasonable number
of copies of a supplement to or an amendment of such prospectus as may be
necessary so that, as thereafter delivered to the purchasers of such Registrable
Securities, such prospectus shall not include an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
are made, not misleading;

                  (g) use its best efforts to list all such Registrable
Securities covered by such registration on each securities exchange and
inter-dealer quotation system on which the Common Stock is then listed, with
expenses in connection therewith (not including any future periodic assessments
or fees for such additional listing, which shall be paid by the Company) to be
paid in accordance with Section 4 hereof;

                  (h) use its best efforts to list all Registrable Securities
covered by such registration statement on any securities exchange or
inter-dealer quotation system (in each case, domestic or foreign) not described
in paragraph (g) above as the Selling Holders or any underwriter of such
Registrable Securities shall request, and use its best efforts to obtain all
appropriate registrations, permits and consents required in connection
therewith, and to do any and all other acts and things which may be necessary or
advisable to effect such listing; provided, however, that, (i) notwithstanding
Section 4, the Holders of the Registrable Securities to be so listed shall pay
all costs and expenses incurred by the Company in connection with such listing
and (ii) the Company shall have no obligation to use its best efforts to so list
Registrable Securities if in the good faith opinion of counsel for the Company
such listing shall impose on the Company an ongoing material compliance
obligation;

                  (i) to the extent reasonably requested by the lead or managing
underwriters in connection with any underwritten offering, send appropriate
officers of the Company to attend any "road shows" scheduled in connection with
any such registration; and

                  (j) furnish for delivery in connection with the closing of any
offering of Registrable Securities unlegended certificates representing
ownership of the Registrable Securities being sold in such denominations as
shall be requested by the Selling Holders or the underwriters.

         6. Exchangeable Securities. Zapata shall be entitled, if it intends to
offer any options, rights, warrants or other securities issued or to be issued
by it or any other person that are exercisable or exchangeable for or
convertible into any Registrable Securities ("Exchangeable Securities"), to
register the Registrable Securities underlying such options, rights, warrants or
other securities pursuant to (and subject to the limitations contained in)
Section 2 of this Agreement.

         7.       Underwriting; Due Diligence.

                  (a) If requested by the underwriters for any underwritten
offering of Registrable Securities pursuant to a registration requested under
this Agreement, the Company shall enter into an underwriting agreement, with
such underwriters for such offering, such agreement to contain such
representations and warranties by the Company and such other terms and
provisions as are customarily contained in underwriting agreements with respect
to secondary distributions, including, without limitation, indemnities and
contribution substantially to the effect and to the extent provided in Section 8
hereof and the provision of opinions of counsel and accountants' letters to the
effect and to the extent provided in Section 5(e) hereof. The Selling Holders on
whose behalf the Registrable Securities are to be distributed by such
underwriters shall be parties to any such underwriting agreement. Such
underwriting agreement shall also contain such representations and warranties by
the Selling Holders on whose behalf the Registrable Securities are to be
distributed as are customarily contained in underwriting agreements with respect
to secondary distributions. The Selling Holders may require that any additional
securities included in an offering proposed by a Holder be included on the same
terms and conditions as the Registrable Securities that are included therein.

                  (b) In the event that any registration pursuant to Section 3
shall involve, in whole or in part, an underwritten offering, the Company may
require the Registrable Securities requested to be registered pursuant to
Section 3 to be included in such underwritten offering on the same terms and
conditions as shall be applicable to the other securities being sold through
underwriters under such registration. If requested by the underwriters for such
underwritten offering, the Selling Holders on whose behalf the Registrable
Securities are to be distributed shall enter into an underwriting agreement with
such underwriters, such agreement to contain such representations and warranties
by the Selling Holders and such other terms and provisions as are customarily
contained in underwriting agreements with respect to secondary distributions,
including, without limitation, indemnities and contribution substantially to the
effect and to the extent provided in Section 8 hereof. Such underwriting
agreement shall also contain such representations and warranties by the Company
and such other person or entity for whose account securities are being sold in
such offering as are customarily contained in underwriting agreements with
respect to secondary distributions.

                  (c) In connection with the preparation and filing of each
registration statement registering Registrable Securities under the Securities
Act, the Company shall give the Holders of such Registrable Securities and the
Underwriters, if any, and their respective counsel and accountants, such
reasonable and customary access to its banks and records and such opportunities
to discuss the business of the Company with its officers and the independent
public accountants who have certified the Company's financial statements as
shall be necessary, in the opinion of such Holders and such underwriters or
their respective counsel, to conduct a reasonable investigation within the
meaning of the Securities Act.

         (d)      8.       Indemnification and Contribution.

                  (a)      In the case of each offering of Registrable 
Securities made pursuant to this Agreement, the Company agrees to indemnify and
hold harmless each Holder, its officers and directors, each underwriter of
Registrable Securities so offered and each person, if any, who controls any of
the foregoing persons within the meaning of the Securities Act, from and against
any and all claims, liabilities, losses, damages, expenses and judgments, joint
or several, to which they or any of them may become subject, under the
Securities Act or otherwise, including any amount paid in settlement of any
litigation commenced or threatened which is approved by the indemnifying party
as provided below, and shall promptly reimburse them, as and when incurred, for
any reasonable legal or other expenses incurred by them in connection with
investigating any claims and defending any actions, insofar as such losses,
claims, damages, liabilities or actions shall arise out of, or shall be based
upon, any untrue statement or alleged untrue statement of a material fact
contained in the registration statement (or in any preliminary or final
prospectus included therein) or any amendment thereof or supplement thereto, or
in any document incorporated by reference therein, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; provided, however, that
the Company shall not be liable to a particular Holder in any such case to the
extent that any such loss, claim, damage, liability or action arises out of, or
is based upon, any untrue statement or alleged untrue statement, or any
omission, if such statement or omission shall have been made in reliance upon
and in conformity with information relating to such Holder furnished to the
Company in writing by or on behalf of such Holder specifically for use in the
preparation of the registration statement (or in any preliminary or final
prospectus included therein) or any amendment thereof or supplement thereto.
Such indemnity shall remain in full force and affect regardless of any
investigation made by or on behalf of a Holder and shall survive the transfer of
such securities. The foregoing indemnity agreement is in addition to any
liability which the Company may otherwise have to each Holder, any of such
Holder's directors or officers, underwriters of the Registrable Securities or
any controlling person of the foregoing; provided, further, that this indemnity
does not apply in favor of any underwriter or person controlling an underwriter
(or if a Selling Holder offers Registrable Securities directly without an
underwriter, the Selling Holder) with respect to any loss, liability, claim,
damage or expense arising out of or based upon any untrue statement or alleged
untrue statement or omission or alleged omission in any preliminary prospectus
if a copy of a final prospectus was not sent or given by or on behalf of an
underwriter (or the Selling Holder, if the Selling Holder offered the
Registrable Securities directly without an underwriter) to the person asserting
such loss, claim, damage, liability or action at or prior to the written
confirmation of the sale of the Registrable Securities as required by the
Securities Act and such untrue statement or omission had been corrected in such
final prospectus.

                  (b)      In the case of each offering made pursuant to this
Agreement, each Holder of Registrable Securities included in such offering, by
exercising its registration rights hereunder, agrees to indemnify and hold
harmless the Company, its officers and directors and each person, if any, who
controls any of the foregoing within the meaning of the Securities Act (and if
requested by the underwriters, each underwriter who participates in the offering
and


                                      -13-
   14




each person, if any, who controls any such underwriter within the meaning of the
Securities Act), from and against any and all claims, liabilities, losses,
damages, expenses and judgments, joint or several, to which they or any of them
may become subject, under the Securities Act or otherwise, including any amount
paid in settlement of any litigation commenced or threatened which is approved
by the indemnifying party as provided below, and shall promptly reimburse them,
as and when incurred, for any legal or other expenses incurred by them in
connection with investigating any claim and defending any actions, insofar as
any such losses, claims, damages, liabilities or actions shall arise out of, or
shall be based upon, any untrue statement or alleged untrue statement of a
material fact contained in the registration statement (or in any preliminary or
final prospectus included therein) or any amendment thereof or supplement
thereto, or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, but in each case only to the extent that such untrue statement of a
material fact is contained in, or such material fact is omitted from,
information relating to such Holder furnished in writing to the Company by or on
behalf of such Holder specifically for use in the preparation of such
registration statement (or in any preliminary or final prospectus included
therein). The foregoing indemnity is in addition to any liability which such
Holder may otherwise have to the Company, any of its directors or officers,
underwriters of the Registrable Securities or any controlling person of the
foregoing; provided, however, that this indemnity does not apply in favor of any
underwriter or person controlling an underwriter (or if the Company offers
Registrable Securities directly without an underwriter, the Company) with
respect to any loss, liability, claim, damage or expense arising out of or based
upon any untrue statement or alleged untrue statement or omission or alleged
omission in any preliminary prospectus if a copy of a final prospectus was not
sent or given by or on behalf of an underwriter (or the Company, if the Company
offered the Registrable Securities directly without an underwriter) to the
person asserting such loss, claim, damage, liability or action at or prior to
the written confirmation of the sale of the Registrable Securities as required
by the Securities Act and such untrue statement or omission had been corrected
in such final prospectus.

                  (c) Each party indemnified under Paragraph (a) or (b) of this
Section 8 shall, promptly after receipt of notice of any claim or the
commencement of any action against such indemnified party in respect of which
indemnity may be sought, notify the indemnifying party in writing of the claim
or the commencement thereof; provided that the failure to notify the
indemnifying party shall not relieve it from any liability which it may have to
an indemnified party on account of the indemnity agreement contained in
paragraph (a) or (b) of this Section 8, except to the extent the indemnifying
party was prejudiced by such failure, and in no event shall relieve the
indemnifying party from any other liability which it may have to such
indemnified party. If any such claim or action shall be brought against an
indemnified party, and it shall notify the indemnifying party thereof, the
indemnifying party shall be entitled to participate therein, and, to the extent
that it wishes, jointly with any other similarly notified indemnifying party, to
assume the defense thereof with counsel reasonably satisfactory to the
indemnified party. After notice from the indemnifying party to the indemnified
party of its election to assume the defense of such claim or action, the
indemnifying party shall not be liable to the indemnified party under this
Section 8 for any legal or other expenses

                                      -14-
   15




subsequently incurred by the indemnified party in connection with the defense
thereof; provided that each indemnified party, its officers and directors, if
any, and each person, if any, who controls such indemnified party within the
meaning of the Securities Act, shall have the right to employ separate counsel
reasonably approved by the indemnifying party to represent them if the named
parties to any action (including any impleaded parties) include both such
indemnified party and an indemnifying party or an Affiliate of an indemnifying
party, and such indemnified party shall have been advised by counsel either (i)
that there may be one or more legal defenses available to such indemnifying
party that are different from or additional to those available to such
indemnified party or such Affiliate or (ii) a conflict may exist between such
indemnified party and such indemnifying party or such Affiliate, and in that
event the fees and expenses of one such separate counsel for all such
indemnified parties shall be paid by the indemnifying party. An indemnified
party will not settle any claim or action for which he or it is being
indemnified hereunder unless the terms thereof are first approved in writing by
the indemnifying party, such approval not to be unreasonably withheld. The
indemnifying party may not agree to any settlement of any such claim or action
which provides for any remedy or relief other than monetary damages for which
the indemnifying party shall be responsible hereunder, without the prior written
consent of the indemnified party, which consent shall not be unreasonably
withheld. In any action hereunder as to which the indemnifying party has assumed
the defense thereof with counsel reasonably satisfactory to the indemnified
party, the indemnified party shall continue to be entitled to participate in the
defense thereof, with counsel of its own choice, but, except as set forth above,
the indemnifying party shall not be obligated hereunder to reimburse the
indemnified party for the costs thereof. In all instances, the indemnified party
shall cooperate fully with the indemnifying party or its counsel in the defense
of such claim or action.

                  (d) If the indemnification provided for in this Section 8
shall for any reason be unavailable to or insufficient to hold harmless an
indemnified party in respect of any loss, claim, damage or liability, or any
action in respect thereof, referred to herein, then each indemnifying party
shall, in lieu of indemnifying such indemnified party, contribute to the amount
paid or payable by such indemnified party as a result of such loss, claim,
damage or liability, or action in respect thereof, in such proportion as shall
be appropriate to reflect the relative fault of the indemnifying party on the
one hand and the indemnified party on the other with respect to the statements
or omissions which resulted in such loss, claim, damage or liability, or action
in respect thereof, as well as any other relevant equitable considerations. The
relative fault shall be determined by reference to whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by the indemnifying party on the
one hand or the indemnified party on the other, the intent of the parties and
their relative knowledge, access to information and opportunity to correct or
prevent such statement or omission, but not by reference to any indemnified
party's stock ownership in the Company. In no event, however, shall a Holder be
required to contribute in excess of the amount of the net proceeds received by
such Holder in connection with the sale of Registrable Securities in the
offering which is the subject of such loss, claim, damage or liability. The
amount paid or payable by an indemnified party as a result of the loss, claim,
damage or liability, or action in respect thereof, referred to above in this
paragraph shall be deemed to include, for purposes of this paragraph, any legal
or other

                                      -15-
   16




expenses reasonably incurred by such indemnifying party in connection with
investigating or defending any such action or claim. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

         9.       Rule 144. The Company shall take such measures and file such
information, documents and reports as shall be required by the SEC as a
condition to the availability of Rule 144 (or any successor provision). The
Company shall use its best efforts to cause all conditions to the availability
of Form S-3 (or any successor form thereto) under the Securities Act for the
filing of registration statements under this Agreement to be met as soon as
possible after the completion of the Public Offering.

         10.      Holdback.

                  (a) Each Holder agrees by the acquisition of Registrable
Securities, if so required by the managing underwriter of any offering of equity
securities by the Company, not to sell, make any short sale of, loan, grant any
option for the purchase of, effect any public sale or distribution of or
otherwise dispose of any Registrable Securities owned by such Holder, during the
30 days prior to and the 90 days after the registration statement relating to
such offering has become effective (or such shorter period as may be required by
the underwriter), except as part of such underwritten offering. Notwithstanding
the foregoing sentence, each Holder subject to the foregoing sentence shall be
entitled to sell during the foregoing period any securities of the Company owned
by it in a private sale. The Company may legend and may impose stop transfer
instructions on any certificate evidencing Registrable Securities relating to
the restrictions provided for in this Section 10.

                  (b) The Company agrees, if so required by the managing
underwriter of any offering of Registrable Securities, not to sell, make any
short sale of, loan, grant any option for the purchase of (other than pursuant
to employee benefit plans), effect any public sale or distribution of or
otherwise dispose of any of its equity securities during the 30 days prior to
and the 90 days after any underwritten registration pursuant to Section 2 or 3
hereof has become effective, except as part of such underwritten registration
and except pursuant to registrations on Form S-4, S-8 or any successor or
similar forms thereto.

         11.      Transfer of Registration Rights.

                  (a) A Holder may transfer all or any portion of its rights
under this Agreement to any transferee of Registrable Securities that represent
(assuming the conversion, exchange or exercise of all Registrable Securities so
transferred that are convertible into or exercisable or exchangeable for the
Company's Voting Stock) at least 20% of the then issued and outstanding Voting
Stock of the Company (each, a "Permitted Transferee"); provided, however, that
(i) with respect to any transferee of less than a majority but more than 30% of
the then issued and outstanding Voting Stock, the Company shall not be obligated
to file a registration statement pursuant to a registration request made by such
transferee pursuant to Section 2 hereof on more than two occasions, and (ii)
with respect to any transferee of 30% or less of


                                      -16-
   17




the then issued and outstanding Voting Stock, the Company shall not be obligated
to file a registration statement pursuant to a registration request made by such
transferee pursuant to Section 2 hereof on more than one occasion. No transfer
of registration rights pursuant to this Section shall be effective unless the
Company has received written notice from the Holder of an intention to transfer
at least 20 days prior to the Holder's entering into a binding agreement to
transfer Registrable Securities (10 days in the event of an unsolicited offer).
Such notice need not contain proposed terms or name a proposed Permitted
Transferee. On or before the time of the transfer, the Company shall receive a
written notice stating the name and address of any Permitted Transferee and
identifying the number and/or aggregate principal amount of Registrable
Securities with respect to which the rights under this Agreement are being
transferred and the scope of the rights so transferred. In connection with any
such transfer, the term Zapata as used in this Agreement (other than in Section
2(a)(iv)) shall, where appropriate to assign the rights and obligations
hereunder to such Permitted Transferee, be deemed to refer to the Permitted
Transferee of such Registrable Securities. Zapata and any Permitted Transferees
may exercise the registration rights hereunder in such priority, as among
themselves, as they shall agree among themselves, and the Company shall observe
any such agreements of which it shall have notice as provided above.

                  (b) After any such transfer, the transferring Holder shall
retain its rights under this Agreement with respect to all other Registrable
Securities owned by such transferring Holder.

                  (c) Upon the request of the transferring Holder, the Company
shall execute an agreement with a Permitted Transferee substantially similar to
this Agreement.

         12.      Miscellaneous.

                  (a) Injunctions. Each party acknowledges and agrees that
irreparable damage would occur in the event that any of the provisions of this
Agreement was not performed in accordance with its specific terms or was
otherwise breached. Therefore, each party shall be entitled to an injunction or
injunctions to prevent breaches of the provisions of this Agreement and to
enforce specifically the terms and provisions hereof in any court having
jurisdiction, such remedy being in addition to any other remedy to which such
party may be entitled at law or in equity.

                  (b) Severability. If any term or provision of this Agreement
is held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms and provisions set forth herein shall
remain in full force and effect and shall in no way be affected, impaired or
invalidated, and each of the parties shall use its best efforts to find and
employ an alternative means to achieve the same or substantially the same result
as that contemplated by such term or provision.

                  (c) Further Assurances. Subject to the specific terms of this
Agreement, each of the parties hereto shall make, execute, acknowledge and
deliver such other instruments and documents, and take all such other actions,
as may be reasonably required in order to

                                      -17-
   18




effectuate the purposes of this Agreement and to consummate the transactions
contemplated hereby.

                  (d) Waivers, etc. Except as otherwise expressly set forth in
this Agreement, no failure or delay on the part of either party in exercising
any power or right hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. Except as
otherwise expressly set forth in this Agreement, no modification or waiver of
any provision of this Agreement nor consent to any departure therefrom shall in
any event be effective unless the same shall be in writing and signed by an
authorized officer of each of the parties, and then such waiver or consent shall
be effective only in the specific instance and for the purpose for which given.

                  (e) Entire Agreement. This Agreement contains the final and
complete understanding of the parties with respect to its subject matter. This
Agreement supersedes all prior agreements and understandings between the
parties, whether written or oral, with respect to the subject matter hereof. The

Agreement

deemed to be an original but all of which together shall be one and the same
instrument.

instrument duly executed by an authorized officer of each of the parties.

shall have specified by like notice):

         In consideration of the Recitals, the covenants set forth herein and

Sublessor's use thereof.

with the terms of the Primary Leases, and may only be made by persons authorized
pursuant to the terms of the Primary Leases. The removal of such alterations,

                       ASSUMPTION AGREEMENT AND COVENANTS

         6.2 SUPERIOR MATTERS. This Sublease, and all of Subtenant's rights and
estates hereunder, are and shall always be subject and subordinated to the
Primary Lease and all encumbrances and other matters affecting the building in
which the Demised Premises is situated and the land on which such building is
located. Subtenant acknowledges that it is familiar with the provisions of the
Primary Lease.

                                    ARTICLE 7
                      LIMITATION OF LIABILITY AND INDEMNITY

         7.1 INDEMNITY. Except for injury to any person, or damage to the
property of any person, proximately caused by the Sublessor or agents or
employees of Sublessor, Subtenant shall indemnify and save Sublessor and its
agents and employees harmless from and against all claims (including attorneys'
fees and court costs) arising from any act or omission of Subtenant or
Subtenant's agents, employees or contractors, or arising from any injury to any
person or damage to the property of any person occurring during the term of this
Sublease in or about the Demised Premises, including the Subleased Premises.
Subtenant agrees to use and occupy the Subleased Premises at its own risk and
hereby releases Sublessor, and agents or employees of Sublessor from all claims
for any damage or injury to the full extent permitted by law, unless such damage
or injury is proximately caused by the Sublessor or the agents or employees of
Sublessor.

         7.2 INSURANCE. Subtenant shall secure and maintain in force
comprehensive general liability insurance, including contractual liability
specifically applying to the provisions of this Sublease and completed
operations liability for reasonable and appropriate limits with respect to
bodily injury or death to any number of persons in any one accident or
occurrence and with respect to property damage in any one accident or
occurrence. All insurance maintained in accordance with the provisions of this
Section 7.2 shall be issued by reputable insurance companies. If Subtenant fails
to maintain such insurance, Sublessor, at its election but without obligation to
do so, may procure such insurance as may be necessary to comply with these
requirements, and Subtenant agrees to repay the cost of same to Sublessor on
demand, with interest thereon at the maximum rate permitted by law from the date
of expenditure until paid.

         7.3 CASUALTY OR CONDEMNATION. If the Subleased Premises are damaged by
fire or other casualty or are condemned or taken in any manner for a public use,
and this Sublease and the Primary Lease are not terminated as a result of such
occurrence, it shall be solely the obligation of Landlord pursuant to the terms
of the Primary Lease, and not of Sublessor, to repair, restore or rebuild the
Subleased Premises, and Subtenant shall not be entitled to any award for any
such condemnation.

                                    ARTICLE 8
                         CONDITION OF SUBLEASED PREMISES

         Subtenant shall accept possession of the Subleased Premises, and the
fixtures and appurtenances therein, on the Commencement Date in its then present
condition. Accordingly, Sublessor shall have no obligation what so ever to make
or construct any


   5




improvements within the Subleased Premises. Subtenant shall maintain the
Subleased Premises, and the fixtures and appurtenances therein, in good order,
repair and condition at all times.

                                    ARTICLE 9
                             [INTENTIONALLY OMITTED]



                                   ARTICLE 10
                             FURNITURE AND FIXTURES

         Subtenant may from time to time, and shall at the termination of this
Sublease, remove its trade fixtures, office supplies and movable office
furniture and equipment not attached to the Subleased Premises provided: (a)
Subtenant is not in default of any obligation or covenant under this Sublease at
the time of such removal; and (b) Subtenant promptly repairs all damage caused
by such removal. All other property at the Subleased Premises and any
alteration, installation, addition or improvement in or to the Subleased
Premises (including wall-to-wall carpeting, paneling or other wall covering) and
any other article attached or affixed to the floor, walls or ceiling of the
Subleased Premises shall remain the property of Sublessor and shall remain upon
and be surrendered with the Subleased Premises as part thereof at the
termination of this Sublease (or at the termination of Subtenant's right to
possession of the Subleased Premises), Subtenant hereby waiving all rights to
any payment or compensation therefor.

                                   ARTICLE 11
                         EVENTS OF DEFAULT AND REMEDIES

         11.1 EVENTS OF DEFAULT. Each of the following acts or omissions of
Subtenant or occurrences shall constitute an "Event of Default":

                  (a) Failure by Subtenant to pay rent or any other sum payable
hereunder within ten (10) days after receiving written notice from the Sublessor
that such payment is past due hereunder;

                  (b) Failure to perform or observe any other covenant or
condition of this Sublease by Subtenant to be performed or observed within ten
(10) days after receiving written notice from Sublessor of its failure to
perform or observe any such covenant;

                  (c) Abandonment or vacating of the Subleased Premises or any
significant portion thereof;

                  (d) The filing or execution or occurrence of any of the
following; provided, however, in the case of any such filing or execution or
occurrence which is involuntary with respect to Subtenant, such filing or
execution or occurrence is not vacated within thirty (30)


   6




days after the occurrence thereof: a petition in bankruptcy or other insolvency
proceeding by or against Subtenant; or petition or answer seeking relief under
any provision of the United States Bankruptcy Code, or an assignment for the
benefit of creditors or composition, or a petition or other proceeding by or
against the Subtenant for the appointment of a trustee, receiver or liquidator
of Subtenant or any property of Subtenant or a proceeding by any government
authority for the dissolution or liquidation of Subtenant; or

                  (e) The termination or any occurrence giving rise to a right
of termination of any of the Primary Lease or termination of Sublessor's right
to possession or any occurrence giving rise to a right of termination of
possession of the Demised Premises under the Primary Lease caused (in whole or
in part) by the default of Subtenant under this Sublease.

         11.2 REMEDIES. This Sublease and the term and estate hereby granted and
the demise hereby made are subject to the limitation that if and whenever any
Event of Default shall occur, and so long as such Event of Default remains
uncured, Sublessor may, at its option, in addition to all other rights and
remedies given hereunder or by law or equity, do either of the following:

                  (a) Terminate this Sublease, in which event Subtenant shall
immediately surrender possession of the Subleased Premises to Sublessor; or

                  (b) Enter upon and take possession of the Subleased Premises
and remove Subtenant and all other occupants therefrom, with or without having
terminated the Sublease.

         11.3     LIABILITY OF SUBTENANT UPON TERMINATION.

                  (a) If Sublessor elects to terminate this Sublease by reason
of an Event of Default, then, notwithstanding such termination, Subtenant shall
be liable for and shall pay to Sublessor the sum of all rent and other
indebtedness accrued to the date of such termination, plus, as damages, an
amount equal to the then present value of the rent reserved hereunder for the
remaining portion of the term of this Sublease (had such term not been
terminated by Sublessor prior to the date of expiration stated in Article 2),
less the then present value of the fair rental value of the Subleased Premises
for such period. All present values shall be based on a three percent (3%) per
annum discount rate.

                  (b) If Sublessor elects to terminate this Sublease by reason
of an Event of Default, in lieu of exercising the rights of Sublessor under the
preceding subparagraph, Sublessor may instead hold Subtenant liable for all rent
and other indebtedness accrued to the date of such termination, plus such rent
and other indebtedness as would otherwise have been required to be paid by
Subtenant to Sublessor during the period following termination of the term of
this Sublease measured from the date of such termination by Sublessor until the
date of expiration stated in Article 2 (had Sublessor not elected to terminate
this Sublease on account of such Event of Default) diminished by any "Net
Sums"(as hereinafter defined) thereafter received by Sublessor through reletting
the Subleased Premises during said period. Actions to collect amounts due by
Subtenant provided for in this Section may be brought from


   7




time to time by Sublessor during the aforesaid period, on one or more occasions,
without the necessity of Sublessor's waiting until expiration of such period;
and in no event shall Subtenant be entitled to any excess of rent (or rent plus
other sums) obtained by reletting over and above the rent provided for in this
Sublease. As used herein, the term "Net Sums" refers to all rent, if
any,received by Sublessor through reletting the Subleased Premises following
termination of this Sublease or termination of Subtenant's right to possession
of the Subleased Premises, reduced by any expenses incurred by Sublessor as
provided in Section 11.5.

         11.4 LIABILITY OF SUBTENANT UPON REPOSSESSION. If Sublessor elects to
repossess the Subleased Premises without terminating this Sublease,then
Subtenant shall be liable for and shall pay to Sublessor all rent and other
indebtedness accrued to the date of such repossession, plus rent required to be
paid by Subtenant to Sublessor during the remainder of the term of this Sublease
(had such term not been terminated by Sublessor prior to the date of expiration
stated in Article 2), diminished by any Net Sums there after received by
Sublessor through reletting the Subleased Premises during said period. In no
event shall Subtenant be entitled to any excess of any rent obtained by
reletting over and above the rent herein reserved. Actions to collect amounts
due by Subtenant as provided in this Section 11.5 may be brought from time to
time, on one or more occasions, without the necessity of Sublessor's waiting
until the expiration of the term of this Sublease.

         11.5 ADDITIONAL OBLIGATIONS OF SUBTENANT UPON DEFAULT. In case of an
Event of Default, Subtenant shall also be liable for and shall pay to Sublessor,
in addition to any sum provided to be paid above, (a) broker's fees incurred by
Sublessor in connection with reletting the whole or any part of the Subleased
Premises; (b) the cost of removing and storing Subtenant's or other occupants'
property; (c) the cost of repairing the Subleased Premises into the condition
called for by the terms of this Sublease; and (d) all expenses incurred by
Sublessor in enforcing Sublessor's remedies, including reasonable attorneys'
fees.

         11.6 SUBLESSOR'S RIGHT TO REMEDY DEFAULTS. If Subtenant should fail to
make any payment or cure any default hereunder within the time herein permitted,
Sublessor, without being under any obligation to do so and without thereby
waiving such default, may make such payment and/or remedy such other default for
the account of Subtenant (and enter the Subleased Premises for such purpose),
and thereupon Subtenant shall be obligated to, and hereby agrees to, pay
Sublessor, upon demand, all costs, expenses and disbursements (including
reasonable attorneys' fees) incurred by Sublessor in taking such remedial action
together with interest on all such sums at the highest non-usurious rate
permitted by law from the date of such demand until payment.

         11.7 TENANT'S REMEDIES. In the event of any default by Sublessor,
Subtenant shall be entitled to bring an action for damages and/or for
declaratory or injunctive relief (in addition to any other relief or remedies
that it may have at law or in equity), but prior to any such action Subtenant
will give Sublessor written notice specifying such default with particularity,
and Sublessor shall thereupon have ten (10) days (plus such additional
reasonable period as may be required in the exercise by Sublessor of due
diligence) in which to cure any such default. Unless and until Sublessor fails
to so cure any default after such


   8




notice, Subtenant shall not have any remedy or cause of action by reason
thereof. All obligations of Sublessor hereunder will be construed as covenants,
not conditions; and all such obligations will be binding upon Sublessor only
during the period of its possession of the Subleased Premises and not
thereafter.

                                   ARTICLE 12
                            MISCELLANEOUS PROVISIONS

         12.1 TEXAS LAW TO APPLY. THIS SUBLEASE SHALL BE CONSTRUED UNDER AND IN
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, AND ALL OBLIGATIONS OF THE
PARTIES CREATED HEREUNDER ARE PERFORMABLE IN HARRIS COUNTY,TEXAS.

         12.2 PARTIES BOUND. This Sublease shall be binding on and inure to the
benefit of the parties hereto and their respective heirs, executors,
administrators, legal representatives, successors and assigns.

         12.3 LEGAL CONSTRUCTION. In case any one or more of the provisions
contained in this Sublease shall for any reason be held to be invalid, illegal
or unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provision hereof and this Sublease shall be construed
as if such invalid, illegal or unenforceable provision had never been contained
herein.

         12.4 PRIOR AGREEMENTS SUPERSEDED. This Sublease constitutes the sole
and only agreement of the parties hereto with respect to the Subleased Premises
and supersedes any prior understandings or written or oral agreements between
the parties respecting the within subject matter.

         12.5 NONWAIVER. Neither acceptance of rent by Sublessor nor failure by
Sublessor to complain of any action, non-action or default of Subtenant shall
constitute a waiver of any of Sublessor's rights hereunder. Waiver by Sublessor
of any right for any default of Subtenant shall not constitute a waiver of any
right for either a subsequent default of the same obligation or any other
default. Receipt by Sublessor of Subtenant's keys to the Subleased Premises
shall not constitute an acceptance of surrender of the Subleased Premises.
Failure by Subtenant to complain of any action, non-action or default by
Sublessor shall not constitute a waiver of any of Subtenant's rights hereunder.
Waiver by Subtenant of any right for any default of Sublessor shall not
constitute a waiver of any right for either a subsequent default of the same
obligation or any other default.

         12.6 BROKERS. Each party hereto acknowledges that no broker has been
employed with respect to this Sublease. Sublessor hereby agrees to defend,
indemnify and hold harmless Subtenant, and Subtenant hereby agrees to defend,
indemnify and hold harmless Sublessor, from and against any claim by third
parties for brokerage, commission, finder's or other fees relative to this
Sublease or the subleasing of the Subleased Premises to Subtenant, and any court
costs, attorneys' fees or other costs or expenses arising therefrom, which are
alleged to be due by authorization of the indemnifying party.
