1.3    TREATMENT OF INTERCOMPANY ACCOUNTS; ADJUSTMENT TO PURCHASE PRICE

       Zapata will cause all intercompany indebtedness owed by Protein or any of
its subsidiaries to Zapata or any of its subsidiaries (other than Protein or any
of its subsidiaries), net of any amounts owed by Zapata or any of its
subsidiaries, to Protein or any of Protein's subsidiaries, as reflected on the
audited consolidated balance sheet of Protein as of September 30, 1994 referred
to in Section 2.1(f), to be contributed to the capital of Protein.

       The Purchase Price set forth in Section 1.2 above shall be adjusted for
changes in intercompany accounts after September 30, 1994, as follows:

       1.3(a)  Prior to February 16, 1995, Zapata shall deliver to Buyer the
General Ledger run of its intercompany balances with Protein for the period
ending January 31, 1995, accompanied by a certificate signed by a Vice President
of Zapata to the effect that the General Ledger run is true and correct and has
to his knowledge been prepared on a basis consistent with accounting principles
used in the preparation of the audited balance sheet of Protein as of September
30, 1994.  Within ten (10) days of receiving the General Ledger run, Buyer shall
notify Zapata of any disagreement Buyer may have with the amount of the balance
of the intercompany balance shown on the General Ledger run.

       1.3(b)  Within thirty (30) days following the Closing Date, Zapata shall
deliver to Buyer the General Ledger run of its intercompany balances with
Protein for the period February 1, 1995, through the Closing Date accompanied by
a certificate signed by a Vice President of Zapata to the effect that the
General Ledger run is true and correct and has to his knowledge been prepared on
a basis consistent with the accounting principles used in the preparation of the
audited balance sheet of Protein as of September 30, 1994.  Within ten (10) days
of receiving the General Ledger run, Buyer shall notify Zapata of any
disagreement Buyer may have with the amount of the balance of the intercompany
balance shown on the General Ledger run.

       1.3(c)  In the event Buyer disagrees with the adjustment to the Purchase
Price determined pursuant to either Section 1.3(a) or (b), Zapata and Buyer
shall confer and, in good faith, seek to reconcile the adjustment to the
Purchase Price.  If, after the parties confer, Buyer and Zapata reconcile the
adjustment to Purchase Price, then within three (3) business days, as the case
may be, either Buyer will pay to Zapata any increase to the Purchase Price or
Zapata will pay to Buyer any decrease to the Purchase Price.

       1.3(d)  If Buyer and Zapata are unable to reconcile the adjustment to the
Purchase Price, as soon as practical, and in any event within thirty (30) days,
Buyer and Zapata shall select a nationally recognized accounting firm which
shall determine the balance owing to Buyer or Zapata hereunder, as the case may
be, and the determination of such accounting firm shall be final and binding on
the parties hereto.  The fees and

                                       2

<PAGE>
 
expenses of such accounting firm shall be borne equally by Zapata and Buyer.
The parties hereto agree to cooperate fully with such accounting firm and
furnish such firm with such information as it may require to make such
determination.

       1.3(e)  After the determination of the balance owing to Buyer or Zapata
hereunder, as the case may be, by the accounting firm provided for in Section
1.3(d), within three (3) days after such determination, either Buyer will pay to
Zapata any increase to the Purchase Price or Zapata will pay to Buyer any
decrease to the Purchase Price.

                       2. REPRESENTATIONS AND WARRANTIES

2.1    REPRESENTATIONS AND WARRANTIES OF ZAPATA

       Zapata represents and warrants to and agrees with Buyer as follows:

       2.1(a)  Organization.  Protein is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware.  Protein
has all requisite corporate power and authority needed to carry on its business
as now conducted and is qualified to do business in every jurisdiction in which
the character and location of assets owned by it, or the nature of the business
transacted by it, or both, require qualification, except where the failure to be
so qualified does not and will not have a material adverse effect on the
business, properties, financial condition or results of operations of Protein
and its subsidiaries, taken as a whole ("Material Adverse Effect").

       2.1(b)  Corporate Status.  The authorized capital stock of Protein
consists of one thousand (1,000) shares of common stock of which one thousand
(1,000) shares are validly issued and outstanding, fully paid and nonassessable
and are owned beneficially and of record by Zapata, free and clear of any claim,
lien or encumbrance.

       2.1(c)  Outstanding Options and Warrants.  There are no outstanding
options, warrants, subscriptions, calls, unsatisfied preemptive rights, voting
agreements or other right for the purchase of, and no securities convertible
into, capital stock of Protein.

       2.1(d)  Certificate of Incorporation and Bylaws.  Zapata has delivered to
Buyer true and complete copies of the Certificate of Incorporation and Bylaws of
Protein, each as amended to date; there are no dissolution, liquidation or
bankruptcy proceedings pending, contemplated by or, to the knowledge of Zapata,
threatened against Protein.

       2.1(e)  Execution of Agreement.  Except as set forth in Schedule 2.1(e),
the execution and delivery of this Agreement by Zapata do not and the
consummation of the transactions contemplated hereby by Zapata will not violate
any provision of the Certificate of Incorporation or Bylaws of Zapata, Protein
or any of the Subsidiaries (as hereinafter defined) or result in any conflict
with, breach or violation of, or creation of lien or default under, any
mortgage, indenture, borrowing agreement or other arrangement or instrument

                                       3

<PAGE>
 
to which Zapata, Protein or any of the Subsidiaries is a party or to which any
of their respective assets are subject or, to the best knowledge of Zapata, any
statute, rule, regulation, judicial or governmental decree, order or judgment
applicable to Zapata, Protein or any of the Subsidiaries.  Zapata has the full
corporate power, authority and legal right to enter into this Agreement and to
consummate the transactions contemplated hereby, and the execution, delivery and
performance of this Agreement have been duly authorized by the Board of
Directors of Zapata.  Except as set forth in Schedule 2.1(e), no consent,
approval, authorization, permit or order of any nature whatsoever from any
federal, state or other domestic or foreign government or regulatory body is
required, except (i) such as may be required under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), (ii) such as may
be required under any loan documentation between Protein and the United States
of America (the "Title XI Financing"), and (iii) such other consents, approvals,
authorizations, permits or orders which have heretofore been obtained and are
in full force and effect.

       2.1(f)  Financial Statements of Protein.  Attached hereto as Schedule
2.1(f) are the following unaudited consolidated financial statements of Protein
and its subsidiaries: income statements, balance sheets, statements of cash
flows and the notes relating thereto as at and for the fiscal years ending
September 30, 1994 and September 30, 1993.  At least ten (10) days prior to the
Closing Date, Zapata shall deliver to Buyer the following consolidated audited
financial statements of Protein and its subsidiaries (and Schedule 2.1(f) shall
be deemed to include such audited financial statements): income statements,
balance sheets, statements of cash flows, statement of changes in stockholder
equity and the notes relating thereto as at and for the fiscal years ended
September 30, 1994 and September 30, 1993.  Except as set forth in Schedule
2.1(f), all of the financial statements referred to above in this Section 2.l(f)
will present fairly, in conformity with generally accepted accounting principles
applied on a consistent basis during the periods involved the financial
condition of Protein and its consolidated subsidiaries and the results of their
operations as of the dates and for the periods indicated as being covered
thereby.  (All of the foregoing financial statements are referred to
collectively herein as the "Financial Statements.")

       2.1(g)  Investment in Other Entities.  Except for the entities listed in
Schedule 2.1(g) (the "Subsidiaries"), Protein has no capital stock interests or
other equity interests, or right or option to acquire any equity interest in any
corporation, partnership, limited liability company or other business entity.
Protein owns of record and beneficially the capital stock interests or other
equity interests disclosed in Schedule 2.1(g) and owns good, valid title
thereto, free and clear of any claim, lien or encumbrance.  Each of the
Subsidiaries is duly organized, validly existing and in good standing under the
laws of the jurisdiction in which it was organized.  Each of the Subsidiaries
has all requisite power and authority needed to carry on its business as now
conducted and is qualified to do business in every jurisdiction in which the
character and location of assets owned by it, or the nature of the business
transacted by it, or both, require qualification, except where the failure to be
so qualified would not have a Material Adverse Effect.  Zapata has delivered to
Buyer true and complete copies of the organization documents of the
Subsidiaries, each as amended to date,

                                       4

and there are no dissolution, liquidation or bankruptcy proceedings pending,
contemplated by or, to the knowledge of Zapata, threatened against any of the
Subsidiaries.

       2.1(h)  Absence of Changes.  Except as disclosed in Schedule 2.1(h),
there has not been since September 30, 1994:

               (1) Any material adverse change in the business, properties or
       financial condition of Protein and the Subsidiaries, taken as a whole,
       and no such change is anticipated;

               (2) Any material labor dispute involving or affecting Protein or
       any of the Subsidiaries, and, to the knowledge of Zapata, no such labor
       dispute is threatened or anticipated;

               (3) Any change in consolidated long-term debt, other than
       regularly scheduled payments of principal or changes in the balance of
       the working capital facility maintained by Venture Milling Company
       pursuant to the terms thereof, or the capital stock of Protein or any of
       the Subsidiaries;

               (4) Any cancellation of debts or claims or waiver by Protein or
       any of the Subsidiaries of any right of material value outside the
       ordinary course of business and without adequate consideration;

               (5) Any direct or indirect purchase, redemption or other
       acquisition by Protein or any of the Subsidiaries of any security issued
       by it;

               (6) Any material contract or arrangement made by Protein or any
       of the Subsidiaries with any of its officers, directors or employees or
       any benefit plan or arrangement (whether written or oral) adopted or
       commenced by Protein or any of the Subsidiaries affecting one or more of
       its officers, directors or employees;

               (7) Any action taken or transaction entered into by Protein or
       any of the Subsidiaries other than in the ordinary course of business,
       except for the transactions contemplated by this Agreement;

               (8) Any mortgage, pledge, lien or other encumbrance of any assets
       of Protein or any of the Subsidiaries (except liens and encumbrances
       arising as a matter of law in the ordinary course of business);

               (9) Any incurring of any obligations or liabilities, absolute or
       contingent, except in the ordinary course of business;

                                       5

<PAGE>
 
               (10) Any material obligation or liability (absolute or
       contingent) paid except in the ordinary course of business;

               (11) Any payment of dividends or distributions of any assets of
       any kind whatsoever in respect of Protein's capital stock declared or

               (12) Any sale, transfer or other disposition of, or agreement
       entered into to sell, transfer or otherwise dispose of any assets (except

       except inventory in the ordinary course of business and consistent with
       prior practices;

               (13) Any agreement or arrangement entered into granting any
       preferential rights to purchase any assets, property or rights of Protein
       or any of the Subsidiaries including inventories, or requiring the
       consent of any party to the transfer and assignment of any of such
       assets, property or rights; or

               (14) Any amendment or termination (other than an expiration
       pursuant to its terms) of any material contract, agreement or license to
       which Protein or any of the Subsidiaries is or was a party or by which it
       or any properties of Protein or any of the Subsidiaries is or was
       subject.

       2.1(i)  Tax Returns and Audits.  All federal, state and local tax returns
and tax reports required to be filed with respect to Protein or any of the
Subsidiaries have been timely filed with the appropriate governmental agencies
in all jurisdictions in which such returns and reports are required to be filed
for all periods ending on or prior to the Closing Date.  Schedule 2.1(i) sets
forth a list of all tax returns and tax reports of Zapata, Protein or any of the
Subsidiaries as to which an extension of the time to file is currently in
effect.  All federal, state and local taxes due from or with respect to Protein
or any of the Subsidiaries for all periods ending on or prior to the Closing
Date have been fully paid or are adequately reflected in the Financial
Statements.  To the extent tax liabilities have accrued but have not yet become
due, they have been adequately reflected in the Financial Statements.  There are
no federal, state or local tax liens upon any property or assets of Protein or
any of the Subsidiaries.  Except as set forth in Schedule 2.1(i), there are no
specific tax deficiencies on the part of Zapata, Protein or any of the
Subsidiaries relating to any tax year ended on or before September 30, 1994
which are expected to arise from issues which have been raised or from issues
which have not yet been raised but which are reasonably expected to be raised.
Except as set forth in Schedule 2.1(i), there is not currently pending any audit
of Zapata, Protein or any of the Subsidiaries with respect to any tax.

          For purposes of this Agreement, "taxes" or "tax" includes (a) all net
income, gross income, gross receipts, sales and use, ad valorem, franchise,
profits, licenses, payroll withholding, social security, excise, severance,
occupation, real or personal property taxes, or other taxes, fees, or charges of
any kind whatsoever imposed by a federal, state,

                                       6

<PAGE>
 
county or local taxing authority, together with any interest or penalty thereon
(including, without limitation, United States federal income taxes), and (b) the
liability for the payment of any consolidated tax, including penalty or interest
thereon, of the type described in the immediately preceding subsection (a),
including any federal, state or local consolidated income tax liability,
including any penalty or interest thereon, as a result of being a member of, and
which may be imposed upon, an affiliated group (as defined in Section 1504(a) of
the Internal Revenue Code of 1986, as amended to date, or other applicable law).

       2.1(j)  Litigation and Related Matters.  Except as set forth in Schedule
2.1(j), there is no litigation, proceeding, investigation or claim pending in
any court or before any governmental, regulatory or administrative board, agency
or commission pending or, to the knowledge of Zapata, threatened against Protein
or any of the Subsidiaries.

       2.1(k)  Compliance with Laws.  Except as set forth in Schedule 2.1(k), to
the best knowledge of Zapata, (i) Protein is in compliance in all material
respects with all applicable domestic and foreign laws, rules, regulations,
judgment, orders and other legal requirements affecting its business and
operations and (ii) all licenses, franchises, permits, approvals and other
authorizations that are required in connection with the ownership or leasing and
the operation of the properties and the conduct of the business of Protein have
been obtained or applied for.

       2.1(l)  Insurance.  For the current policy year, Protein carries or
causes to be carried insurance coverage against such casualties, risks and
contingencies, and in such amounts, types and forms, as determined to be prudent
by Zapata and Protein.  All of the foregoing insurance policies are in full
force and effect and all premiums heretofore billed and due have been paid.
Zapata has not received any notification of the cancellation of any of such
policies or to the effect that any such policies will not be renewed.  Set forth
in Schedule 2.1(l) is a list of all insurance policies maintained by or covering
Protein or any of the Subsidiaries for the current year.  Zapata has furnished
Buyer a true and correct copy of each of the insurance policies listed on
Schedule 2.1(l).  To the extent that any insurance policy of, or any risk
retention program provided or guaranteed by, Zapata or any of its subsidiaries
(other than Protein and the Subsidiaries) provides coverage for any property or
assets of Protein or any of the Subsidiaries, such policy, program or coverage
may be terminated at any time after the Closing Date; provided, however, that
Zapata agrees to use its reasonable best efforts to maintain such policies,
programs or coverages (or policies of substantially the same nature) in full
force and effect at all times until their normal expiration dates, provided,
however, that Protein must pay its pro rata share of all costs, fees and
premiums related thereto.  At Closing, Protein's pro rata share of premiums
prepaid by Zapata shall be repaid to Zapata, unless such prepayments shall have
been repaid to Zapata as an adjustment to the Purchase Price pursuant to the
provisions of Section 1.3 hereof.  All premiums due and payable after the
Closing Date shall be paid by Protein directly to Minet Insurance Services, Inc.
of Texas in accordance with Schedule 2.1(l) or to Zapata within ten (10) days
after receipt by Protein of a request for payment thereof by Zapata.  With
respect to the insurance policies and programs maintained by Zapata after

                                       7

<PAGE>
 
the Closing Date as described above, Zapata shall have no liability to Protein
or any of the Subsidiaries for any coverage deficiency, or any costs, expenses
or liabilities arising therefrom, which occur as a result of any claim which
arises out of an incident occurring after September 30, 1994.  To the extent
that the policy limits under any insurance policy shared between Zapata and
Protein hereunder are exceeded, the coverage under such policy shall be
allocated among the parties on the same pro rata basis as the premiums for such
policy were allocated hereunder.  Once the policy limits have been exceeded, the
party that has used more than its allocated share of coverage shall have the
obligation to reimburse the other party, up to the amount of such excess use,
for all amounts that otherwise would have been payable to such other party under
the policy, but for the shortfall.  The limits of coverage under each insurance
policy providing coverage for Protein or any of the Subsidiaries are adequate
for payment of all claims thereunder which have been or are expected to be made
prior to the Closing Date or adequate provision for such claims has been or will
be made in the Financial Statements.

       2.1(m)  Properties.  Protein and each of the Subsidiaries has good and
marketable title, subject to all matters of record and/or visible on the ground,
to all of its properties and assets, as listed on Schedule 2.1(m), free and
clear of all liens, security interests and encumbrances, except as set forth in
the Financial Statements or as otherwise disclosed in Schedule 2.l(m) and except
for such liens, security interests and encumbrances as may have arisen in the
ordinary course of business as a matter of law and, with respect to the real
property of Protein and its Subsidiaries, such imperfections in title as may
exist that do not have any material adverse effect on the ability of Protein and
the Subsidiaries to use such real properties in a manner consistent with past
practice.  The plants, structures, leasehold improvements, equipment, furniture
and other tangible assets owned or leased by Protein and the Subsidiaries
comprise all of the fixed tangible assets necessary for the operation of the
businesses of Protein and the Subsidiaries, taken as a whole, in accordance with
their current methods of operation and such assets, considered in the aggregate,
are in satisfactory operating condition and repair, subject only to ordinary
wear and tear.  EXCEPT AS SET FORTH HEREIN, ZAPATA EXPRESSLY DISCLAIMS ANY
WARRANTY AS TO THE CONDITION OF ANY ASSETS OR PROPERTIES OF PROTEIN INCLUDING
ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY AND ANY IMPLIED OR EXPRESS
WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

       2.1(n)  Contracts and Other Agreements.  Except for contracts and
documents listed in Schedule 2.1(n), to the best knowledge of Zapata, neither
Protein nor any of the Subsidiaries is a party to or bound by any written or
oral (i) contract not made in the ordinary course of business; (ii) employment
contract; (iii) lease with respect to any property, real or personal, whether as
lessor or lessee requiring total lease payments within any twelve (12) month
period in excess of $25,000; (iv) contract for the future purchase or sale of
materials, supplies or equipment involving total payments within any twelve (12)
month period in excess of $100,000; (v) contract or commitment for any capital
expenditure in excess of $100,000; (vi) contract involving total payments in
excess of $25,000 that is not

                                       8

<PAGE>
 
terminable or cancelable within sixty (60) days of the date hereof; or (vii) any
other lease, agreement, contract or commitment that, to the knowledge of Zapata,
is material to the business and operations of Protein and the Subsidiaries taken
as a whole.  True and correct copies of the documents listed on Schedule 2.1(n)
have been made available to Buyer.  To the best knowledge of Zapata, except as
set forth in Schedule 2.1(n), there is no material breach or default (which has
not been cured or waived) by Protein or any of the Subsidiaries or, to the best
knowledge of Zapata, by any other party to any lease, agreement, contract or
commitment listed on Schedule 2.1(n) to which Protein is a party, or by which
Protein or any of its property is bound, and, to the best knowledge of Zapata,
no event has occurred which, with notice or lapse of time or both, would
constitute such a breach or default.

       2.1(o)  Employee Benefit Plans.

               (1) Schedule 2.1(o) sets forth a list, which is complete,
       accurate and correct, of all bonus, deferred compensation, medical, stock
       purchase, stock option, insurance, severance, employee welfare, pension,
       profit sharing, retirement and other employee benefit plans, funds,
       programs or arrangements currently in effect which have been maintained,
       established or contributed to by Protein or any of the Subsidiaries or
       with respect to any of their respective employees (collectively, the
       "Plans").  Zapata has delivered to Buyer true, correct and complete
       copies of the plan documents (including trust, investment management or
       custodial agreements and insurance policies or contracts) relating to the
       Plans.

               (2) Schedule 2.1(o) also identifies each Plan which constitutes
       (i) an "employee pension benefit plan" ("Pension Plan"), as such term is
       defined in Section 3(2) of the Employee Retirement Income Security Act of
       1974, as amended ("ERISA"), (ii) an "employee welfare benefit plan"
       ("Welfare Plan"), as such term is defined in Section 3(1) of ERISA, or
       (iii) a "multiemployer plan" ("Multiemployer Plan"), as such term is
       defined in Section 4001 of ERISA.  Each Pension Plan which is intended to
       be qualified under Section 401(a) of the Internal Revenue Code of 1986,
       as amended (the "Code") has received a favorable determination letter
       from the Internal Revenue Service (the "IRS"); to the best knowledge of
       Zapata, nothing has occurred which has resulted or is likely to result in
       the revocation of such qualification; and Zapata has delivered to Buyer a
       copy of the most recent determination letter for each Pension Plan.  Each
       Pension and Welfare Plan has been administered in all material respects
       in accordance with ERISA, and Zapata has delivered to Buyer true, correct
       and complete copies of the most recent IRS Form 5500 Series filing for
       each Pension or Welfare Plan and each Pension Plan's most recent annual
       actuarial valuation report and certified financial audit, both of which
       to the best knowledge of Zapata have been prepared accurately and in
       accordance with standard and reasonable actuarial assumptions and
       generally accepted accounting principles.

               (3) Neither Protein nor any of the Subsidiaries (or any other
       person under common control within the meaning of Section 4001(a)(14) of
       ERISA) has incurred any liability to the Pension Benefit Guaranty
       Corporation ("PBGC"), except for required premium payments, which
       payments have been made when due.  Neither Protein nor any of the
       Subsidiaries (or any other person under common control within the meaning
       of Section 4001(a)(14) of ERISA) has ceased operations at any facility or
       withdrawn from a Pension Plan in a manner which could subject it to
       material liability under Section 4062, 4063 or 4064 of ERISA, and no
       events have occurred which might give rise to any liability of Protein or
       any of the Subsidiaries (or any other person under common control within
       the meaning of Section 4001(a)(14) of ERISA) to the PBGC under Title IV
       of ERISA or which could reasonably be anticipated to result in any claims
       being made against Buyer by the PBGC.  Neither Protein nor any of the
       Subsidiaries (or any other person under common control within the meaning
       of Section 4001(a)(14) of ERISA) has incurred any withdrawal liability
       (including any contingent or secondary withdrawal liability) within the
       meaning of Sections 4201 and 4204 of ERISA to any Multiemployer Plan.

               (4) Full payment has been made of all amounts which Protein or
       any of the Subsidiaries is required under applicable law to make to any
       Pension or Welfare Plan or any agreement relating to any Pension or
       Welfare Plan, as a contribution to each Pension or Welfare Plan, as of
       the last day of the most recent fiscal year of such Pension or Welfare
       Plan ended prior to the date hereof, and no accumulated funding
       deficiency (as defined in Section 302 of ERISA and Section 412 of the
       Code), whether or not waived, exists with respect to any Pension Plan.
       The Financial Statements reflect adequate provisions for reserves to meet
       contributions relating to periods ended prior to October 1, 1994, which
       have not been made because they were not yet due under the terms of any
       Pension Plan or related agreements.  There will be no change on or before
       the Closing Date in the operation of any Pension or Welfare Plan or
       documents under which any such Plan is maintained which will result in a
       material increase in the benefit liabilities under such Plan.

               (5) No Reportable Event (as such term is defined in Section 4043
       of ERISA) for which the thirty (30) day notice requirement has not been
       waived by the PBGC has occurred with respect to any Pension Plan other
       than the transactions contemplated by this Agreement.  To the best
       knowledge of Zapata, neither Protein nor any of the Subsidiaries has
       engaged in any transaction with respect to any Plan which would subject
       Zapata, Protein or any of the Subsidiaries to a tax, penalty or liability
       for prohibited transactions under ERISA or the Code.  To the best
       knowledge of Zapata, no director, officer or employee of Zapata, Protein
       or any of the Subsidiaries, to the extent he is a fiduciary with respect
       to any Pension or Welfare Plan, has breached any of his responsibilities
       or obligations imposed upon fiduciaries under Title I of ERISA or which
       would

                                       10

<PAGE>
 
       result in any material claim being made under, by or on behalf of any
       Pension or Welfare Plan.

               (6) As of October, 1993, the current value of the assets of each
       Pension Plan which is subject to Title IV of ERISA exceeded the
       accumulated benefit obligations of all participants and beneficiaries in
       such Plan when such benefits were determined under the Financial
       Accounting Standards Board's Statement of Financial Accounting Standards
       No. 87.

               (7) Except as disclosed on Schedule 2.1(o), neither Zapata,
       Protein nor any of the Subsidiaries has (i) any material liability for
       unfunded retiree medical plans, or (ii) any material liability related to
       a failure to satisfy the group health plan continuation requirements
       under Section 4980B of the Code and Section 601 et seq. of ERISA.

       2.1(p)  Intellectual Property.  Attached hereto as Schedule 2.1(p) is a
list of all trademarks, trademark registrations, trademark registration
applications and trade names which either Protein or any of the Subsidiaries
owns or uses and each license agreement in respect of such intellectual property
that is utilized in the operation of the business of either Protein or any of
the Subsidiaries under which either Protein or any of the Subsidiaries is either
licensor or licensee.

       2.1(q)  Absence of Undisclosed Liabilities.  Except as set forth in the
Financial Statements and except for liabilities and obligations arising under
contracts, claims, proceedings and other matters identified in any schedule
delivered or to be delivered to Buyer pursuant to this Agreement, to the best
knowledge of Zapata, neither Protein nor any of the Subsidiaries has, and none
of the assets or properties of either Protein or any of the Subsidiaries is
subject to, any liabilities (accrued, absolute, contingent or otherwise) which,
net of insurance proceeds, exceed, in the aggregate, the liabilities reflected
in the Financial Statements, whether or not such liabilities are normally shown
or reflected on a balance sheet prepared in a manner consistent with generally
accepted accounting principles, other than obligations under operating leases
and Federal income taxes in respect of the operations of Protein or any of the
Subsidiaries since September 30, 1994.  Except as reflected in the Financial
Statements, neither Protein nor any of the Subsidiaries is in default in respect
of any term or condition of any material indebtedness or liability.  There are
no facts in existence on the date hereof which, to the knowledge of Zapata, are
expected to create or result in any liabilities or obligations of Protein or any
of the Subsidiaries not contemplated by Section 3.1(b) of this Agreement or in
the schedules delivered by Zapata to Buyer pursuant to this Agreement.

       2.1(r)  Questionable Payments.  To the best knowledge of Zapata, neither
Protein nor any of the Subsidiaries nor any employee, agent or representative
thereof has made, directly or indirectly, any bribes, kickbacks, illegal
payments, political contributions with corporate funds, payments from corporate
funds not recorded on the appropriate books

                                       11

<PAGE>
 
and records, payments from corporate funds that were falsely recorded on the
books and records of Protein or any Subsidiary, payments from corporate funds to
governmental officials for improper purposes or illegal payments from corporate
funds to obtain or retain business within or without the United States which, in
the case of any of the foregoing, would constitute a violation of the Foreign
Corrupt Practices Act.

       2.1(s)  Environmental Matters.  To the best knowledge of Zapata, except
as disclosed in Schedule 2.1(s), neither Protein nor any of the Subsidiaries has
(i) any liability under any Environmental Law (as hereinafter defined), as
currently in effect, except to the extent such liability could not be reasonably
expected to result in a Material Adverse Effect on Protein or the Subsidiaries,
(ii) any knowledge of the presence of any Hazardous Substances on, under or at
any of Protein's or any of the Subsidiaries' properties or the presence on,
under or at any other property of any Hazardous Substances generated or released
from Protein's or any of the Subsidiaries' properties, prior to the date hereof
that constitutes a violation of any applicable Environmental Law or a
significant threat to human health or the environment, or (iii) received any
written notice within the last eighteen (18) months (a) of any violation of any
statute, law, ordinance, regulation, rule, judgment, decree or order of any
governmental entity relating to any matter of pollution, protection of the
environment, environmental regulation or control or regarding Hazardous
Substances on or under any of Protein's or any of the Subsidiaries' properties
or any other properties (collectively, "Environmental Laws") or the institution
or pendency of any suit, action, claim, proceeding or investigation by any
governmental entity or any third party in connection with or resulting from any
such violation, (b) requiring the response to or remediation of Hazardous
Substances at or arising from any of Protein's or any of the Subsidiaries'
properties or any other properties, or (c) demanding payment for response to or
remediation of Hazardous Substances at or arising from any of the Protein's or
any of the Subsidiaries' properties or any other properties.  For purposes of
this Agreement, the term "Hazardous Substances" shall mean any toxic or
hazardous materials or substances, including asbestos, buried contaminants,
pollutants, chemicals, flammable explosives, radioactive materials, oil,
petroleum and petroleum products and any substances defined as, or included in
the definition of "hazardous substances", "hazardous wastes", "hazardous
materials" or "toxic substances" under any Environmental Law.

          To the best knowledge of Zapata, except as disclosed in Schedule
2.1(s), (i) no Environmental Law imposes any obligation upon Protein or the
Subsidiaries arising out of or as a condition to any transaction described in
this Agreement, including, without limitation, any requirement to modify or to
transfer any permit or license, any requirement to file any notice or other
submission with any governmental entity, the placement of any notice,
acknowledgement or covenant in any land records, or the modification of or
provision of notice under any agreement, consent order or consent decree and
(ii) no lien or encumbrance has been placed upon any of Protein's or the
Subsidiaries' properties under any Environmental Law.

<PAGE>
 
       2.1(t)  Transfer of Shares.  Zapata is the lawful owner of the Shares to
be sold, transferred and delivered to Buyer hereunder, and the sale, transfer
and delivery of the Shares to Buyer at the Closing will transfer to Buyer valid
title to the Shares, free and clear of all liens, charges, encumbrances and
claims whatsoever.

       2.1(u)  Survival.  All representations, warranties and covenants made in
this Agreement shall survive the Closing for a period of twelve (12) months
following the Closing Date, except that (i) Section 2.1(i) shall survive the
Closing until the expiration of the statute of limitations (including any
extension thereof) applicable to a particular Tax Claim, and (ii) Section 2.1(l)
shall survive the Closing for a period of thirty-six (36) months following the
Closing Date.  All representations, warranties and covenants made in this
Agreement shall terminate as set forth in the preceding sentence and be of no
further force and effect except to the extent they relate to claims made in
writing pursuant to Section 6.3 prior to the end of the applicable period.

2.2  REPRESENTATIONS AND WARRANTIES OF BUYER.

       Buyer represents and warrants to and agrees with Zapata as follows:

       2.2(a)  Organization.  Buyer is a corporation duly organized, validly
existing and in good standing under the laws of the State of Texas.  Buyer has
all requisite corporate power and authority needed to carry on its business as
now conducted.  A majority of the outstanding capital stock of Buyer is owned by
Bankhouse Texas, a Pennsylvania business trust ("BT").  Except for BT's control
of Buyer, no other person or entity controls, is controlled by or is under
common control with either BT or Buyer.  Without limiting the generality of the
foregoing, no person or entity has the right to 50% or more of the profits of BT
or the right to 50% or more of the assets of BT upon the dissolution of BT, and
no person or entity has the contractual power presently to designate 50% or more
of the trustees of BT.  BT is not a party to the financing obtained by Buyer for
purposes of funding the payment of the Purchase Price and is not a guarantor
with respect to such financing.  BT and Buyer are newly formed entities
established for purposes of acquiring Protein, and neither of them has
previously had any revenue-generating activities.  BT and Buyer do not, either
individually or considered together, have total assets of $10,000,000.00 or more
(exclusive of cash to be used by Buyer to pay the Purchase Price).  The
organizational and other transactions effected by Buyer and its shareholders and
their respective affiliates in contemplation of this Agreement, and the
organizational structure resulting therefrom, were undertaken for, and reflect,
bona fide business purposes, including obtaining financing and implementing a
bona fide allocation of ownership, and were not employed for the purpose of
avoiding the obligation to comply with the requirements of the HSR Act.  As used
in this Section 2.2(a), the terms "person," "entity," "control," "controlled by"
and "under common control with" have the meanings specified in the premerger
notification rules of the Federal Trade Commission, 16 CFR Parts 801-803.

                                       13

<PAGE>
 
       2.2(b)  Execution of Agreement.  The execution and delivery of this
Agreement by Buyer do not and the consummation of the transactions contemplated
hereby by Buyer will not violate, result in any conflict with, breach or
violation of, or creation of lien or default under any provision of the Articles
of Incorporation or bylaws of Buyer or with any judgment, order, injunction,
decree, award or any statute, rule, regulation judicial or governmental decree,
order or judgment applicable to Buyer or any mortgage, indenture, borrowing
agreement or other arrangement or instrument to which Buyer is a party or to
which any of its properties is subject.  Buyer has the full corporate power,
authority and legal right to enter into this Agreement and to consummate the
transactions contemplated hereby, and the execution, delivery and performance of
this Agreement have been duly authorized by all necessary corporate action by
Buyer.

       2.2(c)  Consents.  No authorizations, approvals, or consents, that have
not previously been obtained, of any governmental department, commission,
bureau, agency or other public body or authority are required for consummation
of the transactions contemplated by this Agreement except such consents as may
be necessary under the Title XI Financing.  Without limiting the generality of
the foregoing, no filing under the HSR Act is required for consummation of the
transactions contemplated hereby.

       2.2(d)  Articles of Incorporation and Bylaws.  Buyer has delivered to
Zapata true and complete copies of its Articles of Incorporation and Bylaws.
There are no dissolution, liquidation, or bankruptcy proceedings pending,
contemplated by or, to the best knowledge of Buyer, threatened against Buyer.

       2.2(e)  Financing.  Buyer has secured sufficient financing, or otherwise
has sufficient funds available, to permit it to pay the total purchase price set
forth in Section 1.2.

       2.2(f)  Investment Representation.  The Shares are being acquired by
Buyer for its own account and without a view to the sale or distribution
thereof.  Buyer acknowledges that it has been provided with such information as
it deems necessary to enable it to fully evaluate the merits and risks of an
investment in Protein and that it is able to bear the economic risk of the
investment.  Buyer acknowledges that any subsequent disposition of the Shares
(which is not now contemplated) must be made in compliance with the applicable
federal and state securities laws.

       2.2(g)  Disclaimer of Warranties.  EXCEPT AS OTHERWISE PROVIDED HEREIN,
BUYER ACKNOWLEDGES THAT ZAPATA MAKES NO WARRANTY, EXPRESS OR IMPLIED, TO ANYONE,
AS TO PROTEIN, THE BUSINESS IT CONDUCTS OR THE ASSETS IT OWNS. BUYER AFFIRMS
THAT IT HAS INDEPENDENTLY, AND IN ITS SOLE JUDGMENT, SELECTED THE SHARES FOR
PURCHASE AND HAS NOT RELIED UPON ANY STATEMENT OR REPRESENTATION OF ZAPATA
EXCEPT AS CONTAINED IN THIS AGREEMENT IN DECIDING TO PURCHASE THE SHARES.

3.1  ZAPATA'S COVENANTS

       Zapata covenants and agrees as follows:

       3.1(a)  Approvals to be Obtained by Zapata.  Zapata shall use its best
efforts to obtain as soon as possible all required approvals, consents, permits,

       course of business as now conducted;

               (2) Not permit Protein to amend its Certificate of Incorporation
       or Bylaws;

               (3) Not take any action, and not permit Protein to take any
       action, which will result in a breach of any representation, warranty or
       covenant made by Zapata in this Agreement;

               (4) Not permit Protein to guarantee any obligations of others and
       not permit Protein to incur any liabilities or obligations (absolute or
       contingent) except in the ordinary course of business;

               (5) Not permit Protein to mortgage, pledge or subject to any
       security interest, lien, encumbrance, claim, proscription, restriction,
       covenant or easement any of its assets, rights or businesses to secure
       any indebtedness;

               (6) Not permit Protein to increase the pension, retirement or
       other employment benefits of its employees, except as may be required by
       existing agreements, or the compensation of any member of its management,
       except for increases to management compensation consistent with prior
       practice not to exceed a cumulative aggregate of five percent (5%) per
       annum;

                                       15

<PAGE>
 
               (7) Cause Protein to use its reasonable best efforts to preserve
       its business organization intact and to keep available the services of
       its present officers, directors and employees and to preserve the
       goodwill of its suppliers, customers and others having business relations
       with it;

               (8) Not permit Protein to purchase or lease any real property;

               (9) Not permit Protein to change any of its basic policies and
       practices with respect to any material aspect of its business or
       operations;

               (10) Give, and cause Protein to give, Buyer's representatives
       reasonable access during normal business hours to all of Protein's
       assets, books, records, agreements and commitments, and furnish Buyers
       representative during such period with all such information concerning
       Protein's affairs as Buyer may reasonably request.  Buyer shall hold, and
       shall cause its representatives to hold, all such information and
       documents in accordance with, and subject to the terms of, the
       confidentiality agreement referred to in Section 9.3;

               (11) Use its best efforts, and cause Protein to use its best
       efforts, to do and perform all things to be done and performed under this
       Agreement by or on behalf of Zapata and to satisfy all conditions
       precedent to the Closing;

               (12) Not permit Protein to sell, discount or, except in the
       ordinary course of business, compromise any of its notes or accounts
       receivable.

       3.1(c)  Preservation of Books and Records.  For a period of two (2) years
after the Closing Date, Zapata will (i) preserve and retain the corporate,
accounting, legal, auditing and other books and records of Zapata (including,
but not limited to, any documents relating to any governmental or non-
governmental actions, suits, proceedings or investigations arising out of the
conduct of the business and operations of Zapata and its subsidiaries prior to
the Closing Date) which specifically relate to or affect Protein and (ii) make
such books and records available at the then current administrative headquarters
of Zapata to Buyer, and its officers, employees and agents, upon reasonable
notice and at reasonable times, it being understood that Buyer shall be entitled
to make copies of any such books and records as it shall deem necessary.  Zapata
agrees to permit representatives of Buyer to meet with employees of Zapata or
its subsidiaries on a mutually convenient basis in order to enable Buyer to
obtain additional information and explanations of any materials provided
pursuant to this Section 3.1(c).

       3.1(d)  Certain Post-Closing Assistance by Zapata.  Zapata agrees to
cause the appropriate personnel at Zapata to assist Buyer in the prosecution or
defense of any claims and litigation (including counterclaims filed by Buyer)
for which Buyer has indemnified Zapata hereunder.  Such services shall be
rendered by Zapata to Buyer at no cost and expense to Buyer except that Buyer
shall reimburse Zapata for any reasonable out-of-pocket

                                       16

<PAGE>
 
travel and similar expenses incurred by the personnel of Zapata in performing
these functions. Zapata agrees to promptly pay to Buyer upon receipt by Zapata
of any amount collected by Zapata in connection with any action, suit or
proceeding for which Buyer has agreed to indemnify Zapata under Section 6.1.

       3.1(e)  Public Announcements.  Subject to applicable securities law or
stock exchange requirements, at all times until the Closing Date, Zapata will
promptly advise, and obtain the approval of, Buyer before issuing, or permitting
any of Zapata's directors, officers, employees, agents or subsidiaries to issue,
any press release with respect to this Agreement or the transactions
contemplated hereby.

3.2  BUYER'S COVENANTS

       Buyer covenants and agrees as follows:

       3.2(a)  Buyer to Use Best Efforts.  Buyer shall use its best efforts to
cause all things to be done and performed under this Agreement by or on behalf
of Buyer or its designee (including without limitation the obtaining of any
required waivers and consents in connection with the Title XI Financing)

       3.2(b)  No Action Resulting in Breach.  Between the date of this
Agreement and the Closing Date, Buyer will not, without Zapata's prior written
consent, take any action which will result in a breach of any representation,
warranty or covenant made by Buyer in this Agreement.

       3.2(c)  Name Changes.  As soon as practicable after the Closing, and in
any event within three (3) business days of the Closing, Buyer will cause
Protein to change its corporate name to a name which does not use the word
"Zapata" or any word similar to such word.  Buyer acknowledges and agrees that,
except as expressly provided herein, no rights of any kind whatsoever in the
name "Zapata" or in any of the trademarks or service marks of Zapata or any of
its affiliates are being granted or transferred in connection with this
Agreement.  As promptly as practicable after the Closing Date, but in any event
within six (6) months after the Closing Date (subject however, to the following
sentence), Buyer shall refrain from using the word "Zapata" or any word or
expression similar thereto in the name under which it does business or in any
corporate name, trademark, service mark or other name or mark used in connection
with its business; provided, however, that for a period of two (2) years
following the Closing Date, Buyer may use the word "Zapata" in the phrase
"formerly Zapata Protein, Inc." immediately following Buyer's name in marketing
materials prepared by Buyer.  Buyer will not permit Protein to undertake any new
business opportunity or market any new product or enter into any contract or
commitment using the word "Zapata" or any word or expression similar thereto
after the Closing Date.  As promptly as practicable after the Closing Date, but
in any event within two (2) years after the Closing Date, the foregoing name and
the "Stylized Z" logo shall be removed from the assets of Protein and its
Subsidiaries. The parties agree and acknowledge that, in the event

                                       17

<PAGE>
 
of a breach or threatened breach of any of the provisions of this Section
3.2(c), Zapata shall be entitled to immediate and temporary injunctive relief,
as any such breach would cause Zapata irreparable injury for which it would have
no adequate remedy at law. Nothing herein shall be construed so as to prohibit
Zapata from pursuing any other remedies available to it for any such breach or
threatened breach.  Buyer agrees to indemnify and hold harmless Zapata and its
affiliates from any and all damages, losses, costs and expenses (including
reasonable attorneys' fees) incurred by Zapata or any of its affiliates due to
any use of such name or marks by Buyer or any of its affiliates, including
Protein or any of the Subsidiaries at any time after the Closing Date.

       3.2(d)  Employee Benefit Matters.  Effective as of the Closing Date, each
of Protein and the Subsidiaries shall withdraw and terminate its participation
in any employee benefit plan (as defined in Section 3(3) of ERISA) or any other
benefit plan or program sponsored or maintained by Zapata (each a "Zapata Plan")
in which employees of Protein or any of the Subsidiaries participate.  Benefits
accrued and claims incurred by Protein employees with respect to any Zapata Plan
prior to the Closing Date, whether such claims are reported or unreported as of
the Closing Date (including claims incurred as a result of hospitalization at
the Closing Date), shall be the responsibility of Buyer.  No changes shall be
made to or any funds withdrawn by or reverted to Zapata from the Zapata Haynie
Corporation Profit Sharing/Savings Plan and Pension Plan prior to and through
the time of Closing.  For a period of at least eighteen (18) months after the
Closing Date, Buyer shall provide medical and dental benefits for Protein
employees under one of Protein's existing plans or a new plan for similarly
situated employees with medical and dental benefits not less favorable as to
both conditions covered and amounts of coverage and cost of coverage as provided
to Protein employees on the date of this Agreement and any pre-existing
condition restrictions under Buyer's medical plan for the Protein employees will
be waived.

       3.2(e)  Preservation of Books and Records.  For a period of seven (7)
years after the Closing Date, Buyer will (i) preserve and retain the corporate,
accounting, legal, auditing and other books and records of Protein and the
Subsidiaries (including, but not limited to, any documents relating to any
governmental or non-governmental actions, suits, proceedings or investigations
arising out of the conduct of the business and operations of Protein and its
subsidiaries prior to the Closing Date) and (ii) make such books and records
available at the then current administrative headquarters of Protein to Zapata,
and its officers, employees and agents, upon reasonable notice and at reasonable
times, it being understood that Zapata shall be entitled to make copies of any
such books and records as it shall deem necessary.  Buyer agrees to permit
representatives of Zapata to meet with employees of Buyer, Protein or its
subsidiaries on a mutually convenient basis in order to enable Zapata to obtain
additional information and explanations of any materials provided pursuant to
this Section 3.2(e).

                                       18

<PAGE>
 
       3.2(f)  Certain Post-Closing Assistance by Protein.

(1)  Buyer agrees to cause the appropriate personnel at Protein, at no cost or
     expense to Zapata, to prepare all accounting and related reports for
     Protein for periods up to the Closing Date which are required by Zapata in
     connection with Zapata's preparation and filing of various financial, tax
     and accounting reports.

(2)  Buyer agrees to cause the appropriate personnel at Protein to assist Zapata
     in the prosecution or defense of any claims and litigation (including
     counterclaims filed by Zapata) for which Zapata has indemnified Buyer
     hereunder. Such services shall be rendered by Protein to Zapata at no cost
     and expense to Zapata except that Zapata shall reimburse Protein for any
     reasonable out-of-pocket travel and similar expenses incurred by the
     personnel of Protein in performing these functions. Buyer agrees to
     promptly pay to Zapata (or cause Protein to promptly pay to Zapata) upon

                               6. INDEMNIFICATION

6.1  OBLIGATION OF ZAPATA TO INDEMNIFY

               (1) Subject to the limitations contained in this Section 6.1,
       Zapata agrees to hold harmless, indemnify, and defend Buyer (and each of
       its directors, officers, employees and affiliates) from and against any
       and all losses, liabilities, damages, deficiencies, costs or expenses
       suffered, incurred or paid ("Losses" or "Loss," as the case may be) based
       upon, arising out of or otherwise in respect of any inaccuracy in or
       breach of any representation, warranty or covenant of Zapata contained in
       this Agreement (other than any representation or warranty which has
       expired in accordance with Section 2.1(u)).  Zapata's obligations to
       indemnify shall be subject to the following qualifications:

                     (a) Zapata shall not be obligated to indemnify or defend
           Buyer for the first Five Thousand Dollars ($5,000.00) (the "Threshold
           Amount") of each individual Loss arising out of any single event
           condition, third-party claim or demand (each such Loss for the
           purpose of this subsection being referred to as a "Claim" or, in the
           aggregate, "Claims").  The Threshold Amount is not intended to imply
           a standard of materiality for purposes of the representations and
           warranties contained in this Agreement.  A Claim shall not be deemed
           individual, but shall be aggregated for the purposes of this
           Agreement with another Claim or Claims, if all such Claims are
           related.  Claims will not be deemed to be related unless: (i) they
           are shown to be the proximate result of the same specific act,
           omission or event

                                       21

<PAGE>
 
           or (ii) they are shown to be the proximate result of intentional
           repetition of the same specific act or omission by the same person,
           or by a group of persons who intentionally have acted in concert; and

                     (b) Subject to Section 6.1(1)(a) Zapata shall be obligated
           to indemnify Buyer fully and completely for all Losses in excess of
           the Threshold Amount only to the extent they exceed Two Hundred Fifty
           Thousand Dollars ($250,000.00).

               (2) Zapata's indemnification obligations pursuant to this Section
       6.1 shall be limited to an aggregate amount equal to Five Million Dollars
       ($5,000,000.00) (for all Losses except Losses arising from any breach of
       the representations and warranties in Section 2.1(i)).  There shall be no
       limit on Zapata's indemnification obligations for Losses arising from any
       breach of the representations and warranties in Section 2.1(i).

               (3) ln determining the amount of any loss, liability or expense
       for which Buyer is entitled to indemnification under this Agreement (i)
       the gross amount thereof will be reduced by any correlative federal tax
       benefit and by insurance proceeds realized or to be realized by Buyer (or
       by Protein or any Subsidiary of Protein) and (ii) no amount shall be
       included for Buyer's special or consequential damages.

6.2  OBLIGATION OF BUYER TO INDEMNIFY

       Buyer agrees to hold harmless, indemnify and defend Zapata (and each of
its directors, officers, employees and affiliates) from and against any Losses
based upon, arising out of or otherwise in respect of any inaccuracy in or
breach of any representation, warranty or covenant of Buyer contained in this
Agreement.  Buyer's indemnification obligations pursuant to this Section 6.2
shall be limited to an amount equal to Five Million Dollars ($5,000,000.00) (for
all Losses except Losses arising from any breach of the representations and
warranties in Sections 2.2(a) and 2.2(c)).  There shall be no limit on Buyer's
indemnification obligations for Losses arising from any breach of the
representations and warranties in Sections 2.2(a) and 2.2(c).

6.3  INDEMNIFICATION PROCEDURE

       6.3(a)  Notice. Promptly after any party hereto claiming indemnification
under this Agreement (hereinafter the "Indemnified Party") has notice of or
knowledge of the occurrence of any event which the Indemnified Party asserts is
an indemnifiable claim or promptly, but in no event more than ten (10) business
days, after the commencement of any action, claim, or proceeding commenced
against the Indemnified Party by a third party that might result in any claim
for indemnity pursuant to this Agreement (hereinafter referred to as a "Third
Party Claim"), the Indemnified Party shall notify the party obligated to provide

                                       22

<PAGE>
 
indemnification hereunder (the "Indemnifying Party").  Either such notice is
hereafter referred to as a "Commencement Notice."  The Commencement Notice shall
include a reasonably detailed description of the nature of the claim, an
estimate of the amount of damages attributable to the claim and a statement of
the basis of the Indemnified Party's request for indemnification under this
Agreement.  In the case of a Third Party Claim, the Indemnified Party shall
transmit, together with the Commencement Notice, a copy of all papers served
with respect to such claim.  In the event the Indemnified Party fails to provide
a Commencement Notice with respect to a Third Party Claim pursuant to the terms
of this Section 6.3(a) and such failure materially adversely affects the ability
of the Indemnifying Party to defend the Third Party Claim, then the Indemnified
Party shall be deemed to have waived its indemnification rights as to such Third
Party Claim.

       6.3(b)  Post-Notice Procedures.  The following procedures shall apply to
a response to a claim for indemnity by the Indemnified Party.

               (1) Promptly after receipt by the Indemnifying Party of the
       Commencement Notice, the Indemnifying Party shall, (i) within fifteen
       (15) business days of receipt of a Commencement Notice with respect to a
       Third Party Claim, notify the Indemnified Party (A) whether the
       Indemnified Party disputes its potential liability to the Indemnified
       Party under this Article 6 with respect to such Third Party Claim and (B)
       whether the Indemnifying Party desires to defend the Indemnified Party
       against such Third Party Claim and (ii) within sixty (60) business days
       of receipt of a Commencement Notice with respect to a claim other than a
       Third Party Claim, either (A) acknowledge the debt, liability or
       obligation for which indemnity is sought as a valid claim and shall
       forthwith, subject to the provisions of Sections 6.1 and 6.2, pay the
       Indemnified Party an amount sufficient to discharge such debt, liability
       or obligation; or (B) in the event the Indemnifying Party desires to
       challenge the claim for indemnification, notify the Indemnified Party of
       such challenge.  Failure to respond within the appropriate time period
       following the Commencement Notice shall be deemed acknowledgment of the
       right to be indemnified and give rise to the immediate right in the
       Indemnified Party to payment in full of the amount claimed, subject to
       the provisions of Section 6.1 and 6.2 and 6.3(b)(8).

               (2) If the Indemnifying Party notifies the Indemnified Party
       within the period specified in Section 6.3(b)(1) that the Indemnifying
       Party elects to assume the defense of the Third Party Claim, then the
       Indemnifying Party shall have the right to defend, at its sole cost and
       expense, such Third Party  claim by all appropriate proceedings.  The
       Indemnifying Party shall have full control of such defense and
       proceedings, including any compromise or settlement thereof, subject to
       the provisions of Section 6.3(b)(4).  The Indemnified Party may
       participate in, but not control, any defense or settlement of any Third
       Party Claim controlled by the Indemnifying Party pursuant to this Section
       6.3(b)(2) and shall bear its own costs and expenses with respect to such
       participation.  In connection

                                       23

<PAGE>
 
       with such participation, the Indemnified Party shall be permitted to have
       reasonable access from time to time to the Indemnifying Party's attorneys
       and be advised by them, upon request, as to the conduct of the defense
       including, but not limited to, such matters as selection of theories of
       action and defense, discovery matters, other motion practice, and general
       trial strategy, such as selection of and order of presentation of
       witnesses.  If it is necessary for some action to be taken or defense to
       be made in respect of the Third Party Claim prior to confirmation by the
       Indemnified Party that the Indemnifying Party will assume such defense,
       the Indemnified Party shall assume such defense with counsel selected by
       the Indemnified Party for the limited purpose of contesting such Third
       Party Claim until the Indemnifying Party assumes such defense.  If the
       Indemnified Party is entitled to indemnification hereunder with respect
       to such Third Party Claim, the Indemnifying Party shall promptly pay all
       Litigation Costs (defined in Section 6.3(b)(7) below) as and when
       incurred by the Indemnified Party in assuming the defense against the
       Third Party Claim, subject to the provisions of Sections 6.1, 6.2 and
       6.3(b)(8).

               (3) Notwithstanding the provisions of paragraph (2) above to the
       contrary, if the character of a Third Party Claim is such that it is
       covered by insurance policies maintained or previously maintained by the
       Indemnified Party, its affiliates or the Indemnifying Party, and the
       insurer under such policies is entitled to select counsel to defend such
       Third Party Claim, then, in the event such insurer confirms coverage with
       respect to the Third Party Claim and assumes the defense thereof, the
       parties acknowledge and agree that counsel selected by such insurer shall
       conduct the defense against the Third Party Claim.  In the event that an
       insurance carrier assumes the defense of the Third Party Claim, any
       Litigation Costs required to be borne by the parties hereto as if such
       Litigation Costs were the result of a defense assumed by the Indemnifying
       Party.

               (4) The Indemnifying Party may settle or compromise any Third
       Party Claim defended by it without the consent of the Indemnified Party,
       provided such settlement or compromise (i) involves only the payment of
       monetary consideration by the Indemnifying Party or consideration or
       agreements given by the Indemnifying Party of a non-monetary nature which
       have no material adverse effect on the Indemnified Party, and (ii) does
       not involve any admission of liability, or stipulations of fact which,
       would reasonably be expected to have a material adverse effect on the
       Indemnified Party or which might prejudice the Indemnified Party in
       subsequent or other litigation.  In the event that the Indemnifying Party
       desires to settle or compromise a Third Party Claim on a basis which the
       Indemnifying Party believes requires the consent of the Indemnified
       Party, the Indemnifying Party shall notify the Indemnified Party in
       writing and describe in such written notice the terms and conditions of
       the proposed settlement or compromise.  Any such consent requested from
       the Indemnified Party shall not be unreasonably withheld.  The failure of
       the Indemnified Party

                                       24

<PAGE>
 
       to give written notice expressly objecting to the terms and conditions of
       the proposed settlement or compromise within ten (10) days after receipt
       of notice shall be deemed for all purposes to be an approval of the
       proposed settlement or compromise described in the notice.  If the
       Indemnified Party reasonably objects to the proposed settlement, the
       Indemnifying Party shall continue to litigate or resist such Third Party
       Claim until a final judgment is rendered by a court of competent
       jurisdiction or until a settlement or compromise is effected pursuant to
       the provisions hereof.

               (5) In the event of a settlement or compromise pursuant to
       Section 6.3(b)(4) above, with respect to a Third Party Claim as to which
       the Indemnified Party is entitled to indemnification hereunder, the
       Indemnifying Party shall pay and otherwise satisfy in full such
       settlement or compromise and shall pay the Litigation Costs borne by it
       as provided in Section 6.3(b)(8).  If a final judgment is rendered
       against the Indemnified Party in respect of a Third Party Claim, then the
       Indemnifying Party shall promptly satisfy such judgment in full and shall
       pay the Litigation Costs borne by it as provided in Section 6.3(b)(8).
       Notwithstanding the foregoing, in no event shall the Indemnifying Party
       be obligated to pay any amount to the extent that payment would cause the
       total amounts paid or to be paid by the Indemnifying Party pursuant to
       its indemnity obligations set forth in this Agreement to exceed the
       maximum indemnity amount specified in Section 6.1 or 6.2.

               (6) If the Indemnifying Party fails or refuses to timely assume
       and prosecute the defense of a Third Party Claim, the Indemnified Party
       shall have the right to assume the defense of such claim by all
       appropriate proceedings with counsel selected by it.  The Indemnified
       Party shall have full control of such defense and proceedings; provided,
       however, that the Indemnified Party may not enter into, without the
       Indemnifying Party's consent, which shall not be unreasonably withheld,
       any compromise or settlement of such Third Party Claim.  In the event
       that the Indemnified Party assumes the defense of a Third Party Claim
       pursuant to this paragraph then, if the Indemnified Party is entitled to
       indemnification hereunder with respect to such Third Party Claim, in such
       event: (i) all Litigation Costs paid or incurred by the Indemnified Party
       in connection with defending such claim shall be paid exclusively by the
       Indemnifying Party directly as and when payment of such Litigation Costs
       is due; and (ii) all costs and expenses of a settlement or compromise of
       such Third Party Claim or upon rendition of a final judgment with respect
       thereto shall be paid exclusively by the Indemnifying Party.
       Notwithstanding the foregoing, if the Indemnifying Party has delivered a
       notice to the Indemnified Party pursuant to Section 6.3(b)(1) to the
       effect that the Indemnifying Party disputes its potential liability to
       the Indemnified Party under this Article 6 and if such dispute is
       resolved in favor of the Indemnifying Party, the Indemnifying Party shall
       not be required to bear the costs and expenses of the Indemnified Party's
       defense pursuant to this paragraph, and

                                       25

<PAGE>
 
       the Indemnified Party shall reimburse the Indemnifying Party in full for
       all costs and expenses of such litigation.  The Indemnifying Party may
       participate in, but not control, any defense or settlement controlled by
       the Indemnified Party pursuant to this paragraph, and the Indemnifying
       Party shall bear its own costs and expenses with respect to such
       participation.  Notwithstanding the foregoing, in no event shall the
       Indemnifying Party be obligated to pay any amount to the extent that
       payment would cause the total amounts paid or to be paid by the
       Indemnifying Party pursuant to its indemnity obligations set forth in
       this Agreement to exceed the maximum indemnity amount specified in
       Section 6.1 or 6.2, as applicable.

               (7) As used herein, the term "Litigation Costs" shall mean
       reasonable costs and expenses paid or incurred by the party or parties
       charged with defending against a Third Party Claim in connection with so
       defending or contesting a Third Party Claim including, without
       limitation, all reasonable retainers required by outside counsel, all
       attorneys' fees and expenses payable to such counsel, fees and expenses
       of expert witnesses, bonds required to obtain injunctive relief, appeal
       or supersedeas bonds, and other costs of court.  The defense against, or
       the contesting of, the Third Party Claim may include, without limitation,
       the bringing and prosecution of (i) suit for declaratory judgment
       regarding the disputed matters, (ii) suit for injunctive relief, (iii)
       counterclaims or cross-claims, (iv) interpleader or impleader actions, or
       (v) any other form of action or defense which is reasonably advisable and
       proper to defend against or contest such Third Party Claim.

            (8) Payments of all amounts owing by an Indemnifying Party pursuant
       to this Article 6 relating to a Third Party Claim shall be made within
       thirty (30) days after the latest of (i) the settlement of such Third
       Party Claim, (ii) the expiration of the period for appeal of a final
       adjudication of such Third Party Claim or (iii) the expiration of the
       period for appeal of a final adjudication of the Indemnifying Party's
       liability to the Indemnified Party under this Agreement.  Payments of all
       amounts owing by an Indemnifying Party with respect to a claim hereunder
       that does not involve a Third Party Claim shall be made within thirty
       (30) days after the later of (i) the expiration of the 60-day indemnity
       notice period with respect to such claim or (ii) the expiration of the
       period for appeal of a final adjudication of the Indemnifying Party's
       liability to the Indemnified Party under this Agreement.

       6.3(c)  Exclusive Remedy.  The indemnification rights and remedies
granted under this Agreement to the Indemnified Party shall be deemed to be
exclusive of any other remedies of the Indemnified Party and shall be in lieu of
any other rights or remedies to which the Indemnified Party would otherwise be
entitled as a result of any breach by the Indemnifying Party of this Agreement,
or any provision hereof.

       such termination shall be without liability to any party to this
       Agreement or any stockholder, director, officer, employee, agent or
       representative of such party.

               (2) If this Agreement is terminated as a result of the negligent
       or willful failure of Buyer to perform its obligations hereunder, Buyer
       shall be fully liable for any and all damages (other than special,
       consequential or punitive damages) sustained or incurred by Zapata.

               (3) If this Agreement is terminated as a result of the negligent
       or willful failure of Zapata to perform its obligations hereunder, Zapata
       shall be fully liable for any and all damages (other than special,
       consequential or punitive damages) sustained or incurred by Buyer.

               (4) Zapata and Buyer hereby agree that the provisions of Section
       9.1 and this Section 7.2 shall survive any termination of this Agreement.
       Any such termination shall not affect the confidentiality agreement
       referred to in Section 9.3.  In the event of any such termination, each
       party promptly will destroy or, if requested, redeliver to the other
       party all documents, work papers and other materials furnished by such
       party relating to the transaction contemplated hereby (including all
       copies made thereof), and all confidential information received by any
       party, or any employee or agent of any party, concerning the other party
       shall be treated in accordance with the confidentiality obligations.

have been disclosed on all other Schedules to this Agreement to the extent that
it should have been disclosed on such other Schedule.  Unless the context
otherwise requires, the inclusion of any specific item in any Schedule hereto is
not meant to imply that the item so included or any other item is or is not
material, and no party shall use the inclusion of any such item in any dispute
or controversy between the parties as to whether any obligation, item or matter
is not described herein or on a Schedule hereto is or is not material for
purposes hereof.  The section headings of this Agreement and titles given to
Schedules to this Agreement are for reference purposes only and are to be given
no effect in the construction or interpretation of this Agreement.

9.9  ARBITRATION

       9.9(a)  All disputes, differences or questions arising out of or relating
to this Agreement (including, without limitation, those as to the validity,
interpretation, breach, violation or termination thereof) shall, at the written
request of either party, be finally determined and settled pursuant to
arbitration in Houston, Texas, by three arbitrators, one to be appointed by
Buyer, and one by Zapata, and a neutral arbitrator to be appointed by such two-
party appointed arbitrators.  The neutral arbitrator shall be an attorney and
shall act as chairman.  Should (i) either party fail to appoint an arbitrator as
hereinabove contemplated within ten (10) days after the party not requesting
arbitration has received such written request, or (ii) the two arbitrators
appointed by or on behalf of the parties as contemplated in this Section 9.9
fail to appoint a neutral arbitrator as hereinabove contemplated within ten (10)
days after the date of the appointment of the last arbitrator appointed by or on
behalf of the parties, then any person sitting as Judge of the United States
District Court for the Southern District of Texas, Houston Division, upon
application of Zapata or of Buyer, shall appoint an arbitrator to fill such
position with the same force and effect as though such arbitrator had been
appointed as hereinabove contemplated.

       9.9(b)  The arbitration proceeding shall be conducted in Houston, Texas,
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association.  A determination, award or other section shall be considered the
valid action of the arbitrators if supported by the affirmative vote of two or
three of the three arbitrators.  The costs of arbitration (exclusive of
attending the arbitration, and of the fees and expenses of legal counsel to such
party, all of which shall be borne by such party) shall be shared equally by
Zapata and Buyer.  The arbitration award shall be final and conclusive and shall
receive recognition, and judgment upon such award may be entered and enforced in
any court of competent jurisdiction.

9.10  BINDING EFFECT; ASSIGNMENT

       This Agreement shall inure to the benefit of and be binding upon the
parties hereto.  Except as otherwise expressly provided for herein, this
Agreement shall not inure to the benefit of, be enforceable by or create any
right or cause of action in any person other than the parties hereto, including
without limitation any shareholder of either Buyer or Zapata.  No party hereto
shall assign this Agreement or any part hereof without the prior written consent
of the other party.  No such assignment shall release a party of any of its
obligations under this Agreement unless the other party hereto shall have
consented to such assignment in writing.

9.11  EXECUTION OF ADDITIONAL DOCUMENTS

       Each party hereto shall make, execute, acknowledge and deliver such other
instruments and documents and take all such other actions as may be reasonably
required to effectuate the purposes of this Agreement and to consummate the
transactions contemplated hereby.

9.12  INTERPRETATION.  When a reference is made in this Agreement to Sections,
such reference shall be to a Section of this Agreement unless otherwise
indicated.  The phrase "made available" in this Agreement shall mean that the
information referred to have been made available if requested by the party to
whom such information is to be made available.  Unless the context otherwise
requires, "or" is disjunctive but not necessarily exclusive, and words in the
singular include the plural and in the plural include the singular.  When the
context so requires in this Agreement, the masculine gender includes the
feminine and/or neuter.  Any representations and warranties of Zapata that are
qualified by the phrase "to the best knowledge of Zapata" or phrases with
similar wording shall be interpreted to refer to the knowledge, after reasonable
investigation, of Messrs. Malcolm I. Glazer, Lamar C. McIntyre, Joseph L. von
Rosenberg, Kenneth W. Robichau, Mark H. Frank, Sharon M. Brunner and Robert A.
Gardiner.

9.13  COUNTERPARTS

       This Agreement may be executed in two or more counterparts, each of which
shall be deemed to be an original, but all of which together shall constitute
one and the same instrument.
