                TERRA INDUSTRIES TO SELL DISTRIBUTION BUSINESS

Sioux City, Iowa (May 3, 1999) - Terra Industries Inc. (NYSE symbol: TRA) today
announced that it has signed a contract to sell its Distribution business to
Cenex/Land O'Lakes Agronomy Company for $361 million, adjusted for changes to
working capital levels and other costs. The transaction, which is subject to
customary conditions to closing including regulatory review under the 
Hart-Scott-Rodino Act and approval by Terra's lenders, is expected to close
within three months. Terra anticipates a loss of less than $10 million on the
transaction and will use sale proceeds primarily to reduce its debt obligations.

In the pending transaction, Cenex/Land O'Lakes would acquire all rights to the
Distribution business' earnings from April 1, 1999 forward. Included in the sale
are Terra's approximately 400 retail farm service centers in the U.S. and
Canada, and its 50% ownership position in the Omnium chemical formulation plants
in St. Joseph, Missouri, and Blytheville, Arkansas. The Distribution business,
which includes about 2,600 employees in 31 states and Canada, reported 1998
revenues of $1.73 billion and operating income of $21.4 million. Cenex/Land 
O'Lakes plans to offer employment to all employees in Terra's Distribution
business.

Cenex/Land O' Lakes and Terra have also entered into a three-year nitrogen
fertilizer supply agreement through which Cenex/Land O'Lakes will purchase
approximately the quantity that Terra Nitrogen currently supplies to both the
Distribution business and Cenex/Land O'Lakes.

Announcing the transaction, Burton M. Joyce, Terra's President and CEO, said,
"Terra is taking this action to provide the company a stronger financial base.
With less debt Terra will have greater flexibility both to weather the trough of
the current nitrogen cycle and to take advantage of future opportunities. The
Distribution business has been a valuable part of the company for over thirty
years, but under current market conditions Terra and its Board of Directors
believe this sale is a prudent step for the company. The skilled, dedicated
employees in this business will certainly be an asset to Cenex/Land O' Lakes, as
they have been to Terra.

"As a result of this transaction, Terra also expects to eliminate approximately
100 positions in our corporate office. The support functions these individuals
provided will no longer be necessary either for the Distribution business or for
Terra's new structure after the sale is concluded."

Cenex/Land O'Lakes Agronomy Company is owned by Land O'Lakes and Cenex Harvest
States agricultural cooperatives with revenues in excess of $14 billion. These
cooperatives provide farm inputs, services, marketing and value-added processing
to farmers and ranchers.

Terra Industries Inc., with 1998 revenues of over $2.5 billion, is a leading
marketer and producer of fertilizer, crop protection products, seed and services
for agricultural, turf, ornamental and other growers. Terra also produces
industrial nitrogen products and methanol.

officer setting forth its objections to the Draft Audited Closing Balance Sheet

therefor and calculations which, in its view, are necessary to eliminate such
objections. In the event neither Party so objects within such 30-day period, the
Draft Audited Closing Balance Sheet and the Closing Cash Flow Statement shall be
final and binding for purposes of this Agreement (and the Accounting Firm shall
promptly deliver the Audited Closing Balance Sheet ("Audited Closing

                                      -15-

Balance Sheet")) but shall not limit the representations, warranties, covenants,
and agreements of the Parties set forth elsewhere in this Agreement. If either
Party objects and the Parties cannot resolve such objections within thirty (30)
days of receipt of such list of objections, all remaining disputes shall be
resolved by a nationally recognized independent accounting firm which has not
acted as Buyer's or Seller's regular accounting firms (the "Additional
Accounting Firm"), which Additional Accounting Firm shall be selected jointly by
Buyer and Seller within ten (10) days of the end of the 30-day period for
resolving objections. The Additional Accounting Firm shall be instructed to
resolve such disputes within thirty (30) days. The resolution of disputes by the
Additional Accounting Firm so selected shall be set forth in writing and shall
be conclusive and binding upon all Parties, and the Draft Audited Closing
Balance Sheet and the Closing Cash Flow Statement as so resolved by the
Additional Accounting Firm shall become final and binding upon the date of such
resolution (and the Accounting Firm shall promptly deliver the Audited Closing
Balance Sheet ("Audited Closing Balance Sheet")). The fees and expenses of the
Additional Accounting Firm shall be paid by Buyer, if the disputes are resolved
in favor of Seller, or by Seller, if the disputes are resolved in favor of
Buyer, or, if such disputes are resolved partly in favor of Buyer and partly in
favor of Seller, in such amount by Buyer and Seller as shall be determined by
the Additional Accounting Firm on a basis intended to reflect the relative
success of Buyer, on the one hand, and Seller, on the other, with respect to the
resolution of all such disputes.

Audited Closing Balance Sheet and the Closing Cash Flow Statement become final
and binding (the "Final Statement"), whether because the Parties have no
objections, or because the Parties have resolved their objections, or because
the Additional Accounting Firm has resolved the disputes, (A) if Working Capital
Adjustment minus Price Adjustment as determined in the Final Statement is
greater than Estimated Working Capital Adjustment minus Estimated Price
Adjustment as determined in the Preliminary Statement, Buyer shall pay such
excess, plus interest at the Agreed Rate on such excess from the Closing Date to
the date of payment thereof, to Seller by wire transfer in immediately available
funds to the bank account designated in writing by Seller (Seller shall
designate in writing such bank account within three (3) Business Days after the
Audited Closing Balance Sheet becomes final and binding), or (B) if Estimated
Working Capital Adjustment minus Estimated Price Adjustment as determined in the
Preliminary Statement is greater than Working Capital Adjustment minus Price
Adjustment as determined in the Final Statement, Seller shall pay such excess
plus interest at the Agreed Rate on such excess from the Closing Date to the
date of payment thereof, to Buyer by wire transfer in immediately available
funds to the bank account designated in writing by Buyer (Buyer shall designate
in writing such bank accounts within three (3) Business Days after the Audited
Closing Balance Sheet becomes final and binding). The adjustment provided in
this Section 2.4 shall not preclude any remedy provided herein for any breach of
any representation, warranty, or covenant, and the remedy provided in this
Agreement for any breach of any representation, warranty, or covenant shall not
preclude the adjustment provided in this Section 2.4; provided, however, that
there shall be no double recovery.

     2.5. Allocation of Purchase Price. Seller and Buyer shall allocate the
Purchase Price (as adjusted in accordance with Section 2.4) and the Assumed
Liabilities for tax purposes in accordance with an allocation schedule to be
reasonably prepared by Buyer and reasonably agreed to by Seller, including for
purposes of the payment of deed and similar taxes on all real

                                      -16-
<PAGE>
 
property. Such allocation schedule shall be prepared in accordance with Section
1060 of the Code (or the Canadian equivalent as the circumstances require) and
may be based on independent appraisers chosen by Buyer. In connection with the
determination of the foregoing appraisals and allocation schedule, Seller and
Buyer shall cooperate with each other and provide such information as the other
party reasonably may request. Seller and Buyer each shall report the federal,
state, local, provincial, and other Tax consequences of the purchase and sale
contemplated herein (including the filing of IRS Form 8594) in a manner
consistent with the allocation schedule.

     2.6. Consent of Third Parties. Notwithstanding anything to the contrary in
this Agreement, this Agreement shall not constitute an agreement to assign or
transfer any agreement, contract, lease, Permit, or other arrangement or
instrument or any interest arising thereunder or resulting therefrom if an
assignment or transfer or an attempt to make such an assignment or transfer
without any required Consent would constitute a breach or violation thereof or
affect adversely the material rights of Buyer or Seller thereunder, and any
transfer or assignment to Buyer by Seller of any interest under any such
agreement, contract, lease, Permit, arrangement, or instrument that requires any
Consent shall be made subject to such Consent. In the event any such Consent is
not obtained on or prior to the Closing Date, Seller and Buyer shall continue to
use reasonable efforts to obtain any such Consent after the Closing Date until
such time as such Consent has been obtained, and Seller shall cooperate with
Buyer in any lawful and economically feasible arrangement (including, without
limitation, performance by Seller as agent of Buyer) to provide that Buyer shall
receive the benefit of Seller under any such agreement, contract, lease, Permit,
arrangement, or instrument provided that Buyer shall undertake to pay or satisfy
the corresponding liabilities for the enjoyment of such interest to the extent
Buyer would have been responsible therefor hereunder if such Consent had been
obtained. Without limiting the provisions of Section 3.1 or 3.2, nothing in this
Section 2.6 shall be deemed a waiver by Buyer of its rights to have received on
or before the Closing an assignment and transfer of all of the Assets nor shall
this Section 2.6 be deemed to constitute an agreement to exclude from the Assets
any of the properties, assets, or rights described in Section 2.1.1.

     2.7. Closing. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Dorsey & Whitney
LLP, at 10:00 a.m. local time on the last day of the calendar month in which the
waiting period under the HSR Act has expired (or the next Business Day
thereafter if such last day is not a Business Day), or such other date and place
as may be agreed upon by Buyer and Seller following the satisfaction or waiver
of all conditions to the obligations of Buyer and Seller to consummate the
transactions contemplated hereby (other than conditions with respect to actions
that Buyer and Seller will take at the Closing itself). The date in which the
Closing occurs is referred to hereinafter as the "Closing Date."

     2.8. Joint Property. The provisions of this Article 2 are not intended to
cause any property to be subdivided or jointly owned, and the Parties agree to
resolve in good faith any consequence following from the literal application of
this Article 2 having that effect. If any property leased or licensed from a
third party is not used exclusively in the Business or is leased or licensed
pursuant to an arrangement not exclusive to the Business, the Parties shall use
their best efforts to subdivide such arrangement, and if a subdivision cannot be
accomplished, Seller

                                     -17-
<PAGE>
 
shall sublease or sublicense to Buyer, on mutually agreeable terms, only that
property used primarily in the Business or Seller shall assign such arrangement
to Buyer and Buyer shall sublease or sublicense to Seller, on mutually agreeable
terms, that property not used primarily in the Business. With respect to the
occupancy by the Business of a portion of Terra Center, Buyer shall sublease
pursuant to the Sublease the portion of the premises used directly in the
Business along with appropriate access rights.

     2.9 Certain Liens. Seller is obligated on certain long-term indebtedness
which is secured by a Lien on certain properties shown on Schedule 2.9
("Schedule 2.9 Properties") and which is not prepayable. Notwithstanding any
other provisions of this Agreement, the Liens on the Schedule 2.9 Properties
will remain unsatisfied after the Closing. Seller agrees that it will pay such
indebtedness in accordance with its terms. Seller agrees to obtain a
satisfaction in recordable form of each such Lien upon final payment of the
indebtedness secured thereby.

incorporation. Each Selling Corporation has the corporate power and authority to

or lease and to operate its assets as and in the places where such business is
conducted and such assets are owned, leased, or operated. Seller has delivered
to Buyer, prior to the date of this Agreement, complete and correct copies of

of this Agreement by Terra International has been duly authorized and approved
by its board of directors and its sole stockholder and does not require any
other consent of such corporation or stockholder. Except for the authorization

of this Agreement by Terra Canada does not require any other consent of such
corporation or stockholder. Seller has duly executed and delivered this
Agreement and on the Closing Date Seller will have duly executed and delivered
each of the Seller Ancillary Agreements. This Agreement is, and each of the
Seller Ancillary Agreements upon execution and delivery by Seller will be, the
legal, valid, and binding obligation of Seller enforceable in accordance with
its terms, except as the enforcement thereof may be limited by bankruptcy and
other laws of general application relating to creditors' rights or general
principles of equity.

             4.1.3. No Conflict. Except as set forth in Schedule 4.1.3, none of
the execution, delivery, and performance of this Agreement or any Seller
Ancillary Agreement by Seller, nor the consummation of the transactions

which Seller is a party or any of the Assets is subject or by which Seller is
bound; (v) any of the Plans; (vi) any material Governmental Order to which
Seller is a party or any of the Assets is subject or by which Seller is bound;

affecting Seller or the Assets; or (B) require any Consent of any Person other
than Consents required pursuant to leases, contracts and similar obligations
that are part of the Assets or Consents the failure of which to obtain will not
materially adversely affect the Seller or the operation of the Business taken as
a whole.

             4.1.4.  Financial Statements.
                     -------------------- 

                     4.1.4.1. Seller has delivered to Buyer, prior to the date
of this Agreement, complete and correct copies of unaudited consolidated
financial statements (including balance sheets (such balance sheet as of
December 31, 1998 being referred to herein as the "Year End Balance Sheet"),
statements of income and cash flow, and notes thereto) of the Business as of and
for the years ended December 31, 1997, and December 31, 1998 ("Most Recent
Fiscal Year End"), (the "Year End Financial Statements"). The Year End Financial
Statements (including the notes thereto) are complete and correct and were
prepared in accordance with GAAP, on a consistent basis throughout the periods
covered thereby and consistent with the Accounting Practices, and, together with
the notes thereto, present fairly the consolidated assets, liabilities, and
financial position of the Business at the indicated dates and the results of
operations and cash flows of the Business for the periods indicated. Other than
the accounts receivable described in Section 2.1.2(F) and any other Excluded
Assets (including the interest in Royster-Clark Inc.) and other than the
Excluded Liabilities, the balance sheets included in the Year End Financial
Statements do not include any material asset or liability not intended to
constitute the Business or the Assets after giving effect to the transactions
contemplated hereby. Other than the accounts receivable described in Section
2.1.2(F) and any other Excluded Assets (including the interest in Royster-Clark
Inc.), the statements of income and cash flow included in the Year End Financial
Statements do not reflect the operations of any entity or business not intended
to constitute the Business after giving effect to the transactions contemplated
hereby and reflect all costs that historically have been incurred by the
Business (other than the Excluded Liabilities).

                     4.1.4.2. Seller has delivered to Buyer, prior to the date
of this Agreement, a complete and correct copy of the unaudited consolidated and
consolidating balance sheet (the "Balance Sheet") of the Business as of March
31, 1999 (the "Balance Sheet Date") and the related consolidated and
consolidating statements of income and cash flow of the Business as of and for
the period then ended (collectively, the "Unaudited Financial Statements"). The
Unaudited Financial Statements were prepared in accordance with GAAP, applied on
a basis consistent with the Year End Financial Statements and the Accounting
Practices, subject to normal year-end adjustments. The Unaudited Financial
Statements fairly present the financial position of the Business at the
indicated date and the results of operations of the Business for the

                                      -22-
<PAGE>
 
indicated periods. Other than the accounts receivable described in Section
2.1.2(F) and any other Excluded Assets (including the interest in Royster-Clark
Inc.) and other than the Excluded Liabilities, the Balance Sheet does not
include any material asset or liability not intended to constitute the Business
or the Assets after giving effect to the transactions contemplated hereby. Other
than the accounts receivable described in Section 2.1.2(F) and any other
Excluded Assets (including the interest in Royster-Clark Inc.), the statements
of income and cash flow included in the Unaudited Financial Statements do not
reflect the operations of any entity or business not intended to constitute the
Business after giving effect to the transactions contemplated hereby and reflect
all costs that historically have been incurred by the Business (other than the
Excluded Liabilities).

             4.1.5. Absence of Undisclosed Liabilities. Except as set forth in
Schedule 4.1.5, as of date of this Agreement, to the best knowledge of Seller,
Seller is not subject to any liabilities of any nature, whether known or
unknown, absolute, contingent, accrued, or otherwise, and due or to become due,
arising out of or relating to the Business or the Assets, which liabilities are
not shown or which are in excess of amounts shown or reserved for in the Balance
Sheet, other than liabilities that are (A) of the same nature as those set forth
in the Balance Sheet and reasonably incurred in the Ordinary Course of Business
after the Balance Sheet Date, and (B) individually and in the aggregate are not
material to the Business and have not had or resulted in, and will not have or
result in, a Material Adverse Change.

             4.1.6.  Real Property.
                     -------------

Seller and used primarily in, held primarily for use in connection with,
necessary for the conduct of, or otherwise material primarily to the Business.
Except for Permitted Liens and except as set forth in Schedule 4.1.6 showing the
name of the tenant, date of lease, annual rental, and expiration date, there are
no leases, subleases, licenses, or other rights of use, occupancy, or purchase
affecting such owned real property. Seller also has made available Buyer, prior
to the date of this Agreement, complete and correct copies of all options held
by Seller to acquire any real property not owned by Seller.

                     4.1.6.2. Schedule 4.1.6 lists all real property leases,
subleases, licenses, or other use or occupancy agreements, whether written or
oral (showing the name of the landlord, location, date of lease, annual rental,
expiration date, renewal and purchase options) pursuant to which Seller is the
lessee, sublessee, licensee, user, or occupant which relates primarily to the
operations of the Business other than minor seasonal storage leases with a
duration of less than eight months. Except as described in Schedule 4.1.6,
Seller has the right to use, occupy, and peacefully enjoy all such leased real
property for the full term of each such lease, sublease, license, or use or
occupancy agreement (and any renewal option related thereto).

                     4.1.6.3. Each of the real property listed in Schedule
4.1.6, whether owned, leased, licensed, used, or occupied by Seller, has
adequate ingress and egress for the operation of the Business as currently
conducted and has all utilities and services necessary for the operation of the
real property as presently operated; all such utilities and services are
available to the real property through public rights-of-way or appurtenant
private easements. No such real property, or the operation or use thereof,
violates any material covenant, condition,

                                      -23-
<PAGE>
 
restriction, or easement or any instrument of record or other material
agreement, encroaches in any material respect on any property owned by any
Person, or violates any material Requirement of Law, and Seller has not received
any notice of any such violation or encroachment. There is no pending or, to the
best knowledge of Seller, anticipated change in any Requirement of Law relating
to in the ownership, lease, use, occupancy, or operation of either the whole or
any part of any real property listed in Schedule 4.1.6 that would result in a
Material Adverse Change.

                  4.1.6.4.  To the best knowledge of Seller, neither the whole
nor any part of any real property owned, leased, licensed, used, or occupied by
Seller in the operation of the Business is subject to any pending suit for
condemnation or other taking by any Governmental Body, and, to the best
knowledge of Seller, no such condemnation or other taking is threatened. To the
best knowledge of Seller, there is no Governmental Order or action, claim, suit,
or proceeding by any Person, pending or threatened, relating to the ownership,
lease, use, occupancy, or operation by Seller of any of the real property listed
in Schedule 4.1.6. The real property owned, leased, licensed, used, or occupied
by Seller and listed in Schedule 4.1.6 constitutes all the fee and leasehold
interests in real property held primarily for use in connection with, necessary
for the conduct primarily of, or otherwise material primarily to the Business.

                  4.1.6.5.  To the best knowledge of Seller, each parcel
included in the owned property listed in Schedule 4.1.6 is assessed for real
property tax purposes as a wholly independent tax lot, separate from adjoining
land or improvements not constituting a part of that parcel.

          4.1.7.  Personal Property.
                  ----------------- 

                  4.1.7.1.  The Balance Sheet reflects as of its date all

operations of the Business, except for any such lease, license, or other use
agreement or right that is terminable by Seller without penalty or payment on

Except for the Excluded Assets and subject to receipt of appropriate Consents,
there are no assets used in the operation of the Business and owned by any
Person other than Seller that will not be leased or licensed to Buyer under
valid and current leases or license arrangements.

                   ----- 

                   4.1.14.1.  Seller has timely filed or caused to be filed all
Tax Returns relating to the Business or the Assets which are required to be
filed on or prior to the Closing Date and has paid all material Taxes relating
to the Business or the Assets, whether disputed or not, which are shown on such
Tax Returns to be due or claimed by any taxing authority to be due. Such Tax
Returns have been prepared in accordance in all material respects with all
applicable Requirements of Law. All amounts required to be withheld or collected
by Seller with respect to the Business have been withheld or collected, and
either timely paid to the appropriate Governmental Bodies, set aside in accounts
for such purpose, or accrued, reserved against, and entered upon the books of
Seller as of the Balance Sheet Date.

                   4.1.14.2.  Except as set forth in Schedule 4.1.14, Seller is
not a party to any claim, action, audit, investigation, or other proceeding
pending or, to the best knowledge of Seller threatened in respect of any Tax
relating to the Business or the Assets for which Seller may become liable. Each
deficiency, fine, penalty, addition to Tax, additional amount, or assessment
that has been claimed as a result of any audit of Seller with respect to the
Business is being contested in good faith by appropriate proceedings, and all of
such deficiencies, fines, penalties, additions to tax, additional amounts, and
assessments are set forth in Schedule 4.1.14. Except as set forth in Schedule
4.1.14, Seller has not granted or agreed to any waiver or extension of any
statute of limitations with respect to any Taxes relating to the Business or the
Assets, and Seller has not granted any power of attorney with respect to any
Taxes relating to the Business or the Assets.

                   4.1.14.3.  Buyer will not be required to deduct and withhold
any amount pursuant to Section 1445(a) of the Code upon the transfer of the
Business and the Assets to Buyer.

          4.1.15.  Employee Matters.
                   ---------------- 

                   4.1.15.1.  Except as described in Schedule 4.1.15, Seller is
not, in respect of the Business, a party to or bound by any written or oral:

          (A)  collective bargaining agreements; employment agreements (other
than employment agreements terminable by Seller without premium or penalty on
notice of 30 days or less under which the only monetary obligation of Seller is
to make current wage or salary payments and provide current fringe benefits);
consulting, advisory, or service agreements; deferred compensation agreements;
confidentiality agreements; noncompetition agreements; termination agreements;
severance agreements; change of control agreements; or similar agreements;

          (B)  agreements or arrangements with any officer, director, or
Employee (other than agreements disclosed in response to clause (A) or excluded
from the scope of clause (A)), agent, or attorney-in-fact of Seller; or

                                     -29-
<PAGE>
 
          (C)  stock option, stock appreciation, stock purchase, bonus, or other
incentive plans or agreements.

               4.1.15.2.  Except as described in Schedule 4.1.15, Seller does
not maintain, and is not required to contribute to, and is not subject to any
liability with respect to, any "employee benefit plan," as such term is defined
in Section 3(3) of ERISA, whether or not subject to ERISA. None of the Plans is
a Multiemployer Plan. Each of the plans described in Schedule 4.1.15 (the
"Plans") which is intended to qualify under Section 401(a) of the Code has
received a favorable determination letter from the IRS as to its qualification
under the Code that takes into account the changes required under the Tax Return
Act of 1986 and to the effect that each trust forming a part of any such Plan is
exempt from taxation under Section 501(a) of the Code, and nothing has occurred
since the date of such determination letter that could adversely affect such
qualification or tax-exempt status. Except as set forth in Schedule 4.1.15, each
of the Plans, other than Multiemployer Plans, complies in form in all material
respects and has been administered in all material respects in accordance with
all applicable Requirements of Law.

               4.1.15.3.  Except as described in Schedule 4.1.15, no Plan
provides medical or death benefits (whether or not insured) with respect to the
Employees beyond their retirement or other termination of service other than (A)
coverage mandated by law or (B) death benefits under any Plan intended to
qualify under Section 401(a) of the Code. Seller and each affiliated entity has
complied with the health care continuation requirements of Section 601, et seq.,
of ERISA and Section 4980B of the Code with respect to the Employees, and Seller
will continue to maintain the Plans that are "group health plans" as defined in
Section 4980B(g) of the Code and Section 607 of ERISA for the required coverage
period.

               4.1.15.4.  Except as described in Schedule 4.1.15, there is no
pending or, to the best knowledge of Seller, threatened claim which alleges any
violation of any Plan or any Requirement of Law (A) by or on behalf of any Plans
or fiduciaries of any Plans or (B) by any Employee or any participant or
beneficiary against any Plan. Without limiting the generality of the foregoing,
the execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby will not give rise to any liability on the part
of Buyer, or any of the officers, directors, or employees of Buyer under
Sections 404, 406, 409, 502, 4201, et seq. of ERISA or Section 4975 of the Code.
Furthermore, Seller shall be responsible for and have the obligation for
satisfying any notice requirements in respect of events occurring, services
rendered or compensation paid prior to the Closing Date which are required by
ERISA and the Code regarding its Plans, including without limitation notices
required by Sections 204(h), 606, and 4043 of ERISA and 4980B of the Code.

               4.1.15.5.  All contributions required to have been made by Seller
and each "related person" (as defined in Section 414 of the Code) to any Plan
under the terms of any such Plan or pursuant to any applicable collective
bargaining agreement or Requirement of Law have been made within the earliest
time prescribed by such Plan, collective bargaining agreement, or Requirement of
Law.

               4.1.15.6.  Except as defined in Schedule 4.1.15, the consummation
of the transactions contemplated by this Agreement will not (A) entitle any
Employee to severance pay, unemployment compensation, or any similar payment, or
(B) accelerate the time of payment or

                                     -30-
<PAGE>
 
vesting or increase the amount of any compensation or benefits due to any such
Transferred Employee. No Transferred Employee is or may become entitled to post-
employment benefits of any kind by reason of employment in the Business,
including, without limitation, death or medical benefits (whether or not
insured), other than (i) coverage provided pursuant to the terms of any Plan
specifically identified as providing such coverage in Schedule 4.1.15 or
mandated by Section 4980B of the Code, (b) retirement benefits payable under any
Plan qualified under Section 401(a) of the Code, or (c) deferred compensation
accrued as a liability on the Year End Balance Sheet or incurred after the date
of the Year End Balance Sheet in the Ordinary Course of Business pursuant to the
terms of a Plan.

                   4.1.15.7.  Schedule 4.1.15 lists each current employee of
Seller or any Affiliate used in the Business whose salary exceeds $80,000 per
year and the position, title, remuneration (including any scheduled salary or
remuneration increases), and date of employment. Except as set forth in Schedule
4.1.15, Seller has complied in all material respects with all Requirements of
Law pertaining to the employment of employees, including, without limitation,
those relating to prices, wages, hours, employment practices, discrimination,
labor relations, collective bargaining, and operation of its business and is not
liable for any arrear of wages or any Tax or penalty for failure to comply with
any of the foregoing. Neither Buyer nor Seller is or will be liable for any
retroactive workers' compensation insurance premium or retroactive unemployment
compensation experience rating or charge relating to any period of time prior to
the Closing Date.

                   4.1.15.8.  Except as set forth on Schedule 4.1.15, (A) since
January 1, 1996, no unfair labor practice complaint against Seller has been
brought before, or threatened by, the National Labor Relations Board; (B) since
January 1, 1996, there has not occurred or been threatened any labor strike,
dispute, picketing, slowdown, stoppage, or other similar labor activity against
or involving Seller; (C) Seller is not party to any collective bargaining
agreement and there are no labor unions or other organizations representing,
purporting to represent, or attempting to represent any Employee; (D) Seller has
not experienced any material labor difficulty since January 1, 1996; (E) Seller
has no knowledge that Seller's relations with its Employees are other than
satisfactory; (F) since January 1, 1996, Seller is not a party to, or affected
by or threatened with, any union organizing or election activity or any dispute
or controversy with a union involving the Employees; and (G) Seller is not
affected by any dispute or controversy with a union or with respect to
unionization or collective bargaining involving any supplier or customer of
Seller. As of the date of this Agreement, to the best knowledge of Seller, no
management employee of the Business intends to terminate employment with the
Business.

          4.1.16.  Intellectual Property.
                   --------------------- 

                   4.1.16.1   Schedule 4.1.16 lists all of the Intellectual
Property included in the Assets. The Intellectual Property set forth on Schedule
4.1.16 comprises all of the intellectual property necessary for Buyer to conduct
and operate the Business as now being conducted by Seller, and Seller has not
entered into any license or other agreement with respect to, or otherwise
consented to, the use by any Person of any Intellectual Property except as
described in Schedule 4.1.16.

                                     -31-
<PAGE>
 
                   4.1.16.2.  All patents listed in Schedule 4.1.16 are valid
and in force and all patent applications of Seller listed therein are in good
standing, all without challenge of any kind. All of the registrations for trade
names, trademarks, service names, service marks, and copyrights listed in
Schedule 4.1.16 are valid and in force and all applications for such
registrations are pending and in good standing, all without challenge of any
kind.

                   4.1.16.3.  Except as disclosed in Schedule 4.1.16, Seller
owns the entire right, title, and interest in and to all Intellectual Property
free and clear of all Liens and has the perpetual right to use all Intellectual
Property free from any requirement of any past, present, or future royalty
payments, license fees, or other charges. Upon the Closing, Seller will transfer
to Buyer all Intellectual Property (other than the name "Terra") and Buyer will
have the right to use all Intellectual Property free and clear of all Liens
(other than Liens created by Buyer) or restrictions contemplated by the License
Agreement and on the same terms and conditions as in effect prior to the
Closing. Except as set forth in such Schedule 4.1.16, the use of the
Intellectual Property for the conduct of the Business as currently conducted
does not infringe or violate or allegedly infringe or violate the intellectual
property rights of any Person. Except as set forth in Schedule 4.1.16, to the
best knowledge of Seller, there is no infringing use of any Intellectual
Property by any other Person, and to the best knowledge of Seller, Seller has
not committed any act, or omitted to take any act, as would cause a forfeiture
or abandonment of any material right in any Intellectual Property or would cause
any Intellectual Property to enter the public domain.

          4.1.17   Receivables.  All receivables (including accounts
receivables, notes receivables, and advances) of Seller which have arisen in
connection with the Business and which are set forth in the Year End Financial
Statements and all such receivables that have arisen between the Most Recent
Fiscal Year End and the close of business on the Closing Date are valid and have
and will have arisen from bona fide transactions by Seller in the Ordinary
Course of Business. Such receivables are, to the best knowledge of Seller,
subject to no valid defense or offsets except routine customer complaints of an
immaterial nature. Seller has valid and perfected security, if any, interests in
the security for such receivables (to the extent such priority may be obtained
under applicable law by possession of the security or the filing of financing
statements or similar documents with respect thereto).

          4.1.18.  Inventories.  The Inventories are, subject to any applicable
reserves established in respect thereof on the Balance Sheet, (A) in good,
merchantable, and useable condition, (B) of such quality as to meet the quality
control standards of Seller and its Affiliates and the quality control
requirements of any applicable Governmental Body, (C) salable, if they are
finished goods, as current inventories at the current prices thereof in the
Ordinary Course of Business, (D) reflected in the Balance Sheet in accordance
with GAAP, and (E) reflected in the books and records of Seller and its
Affiliates at the lower of cost or market value on a first-in, first-out basis
consistent with the Accounting Practices. None of the Inventories reflected on
the Balance Sheet is in a quantity in excess of amounts that can be sold by
Seller in the Ordinary Course of Business. The packaging included in the
Inventories is adequate in quantity to enable Buyer to continue to package and
ship finished goods in accordance with Seller's past practices. The inventory
obsolescence policies of Seller are appropriate for the nature of the products
sold and the marketing methods used by Seller, and the reserve for inventory
obsolescence contained in the Balance Sheet fairly reflects the amount of
obsolete inventory as of the Balance Sheet Date.

          4.1.19.  Insurance and Claims.  All policies of insurance maintained,
owned, or held by Seller for the benefit of or in connection with the Assets or
the Business are in full force and effect, and all premiums due thereon have
been paid. Seller shall keep or cause such insurance or comparable insurance in
full force and effect and shall pay all premiums due thereon through the Closing
Date. Seller has complied in all material respects with each of its insurance
policies and has not failed to give any notice or present any claim thereunder
in a due and timely manner. Such insurance insures Seller in amounts and against
losses and risks that Seller believes to be customary for businesses similar to
the Business.

          4.1.20.  Status of Agreements.  Except as set forth in Schedule 4.1.20
or in any other Schedule, and except as relate to Seller's debt arrangements
that are not being assumed by Buyer, each of the leases, agreements, and
arrangements listed in Sections 4.1.6, 4.1.7, 4.1.12, 4.1.15, and 4.1.16
(collectively, the "Material Agreements") constitutes a valid, binding, and
enforceable obligation of the parties thereto and is in full force and effect.
Except as set forth in Schedule 4.1.20, Seller has fulfilled and performed in
all material respects its obligations under each of the Material Agreements,
and, to the best knowledge of Seller, Seller is not in, and is not alleged to be
in, breach or default under, and, to the best knowledge of Seller, there is not
and there is not alleged to be any basis for termination of, any of the Material
Agreements. To the best knowledge of Seller as of the date hereof, no other
party to any of the Material Agreements has materially breached or defaulted
thereunder, and as of the date hereof, no event has occurred and no condition or
state of facts exists which, with the passage of time or the giving of notice or
both, would constitute such a default or breach to the best knowledge of Seller,
by any such other party. Seller is not currently renegotiating any of the
Material Agreements except in the Ordinary Course of the Business or paying
liquidated damages in lieu of performance thereunder.

          4.1.21.  Customers and Suppliers. As of the date of this Agreement, to
the best knowledge of Seller, there exists no actual or threatened termination,
cancellation, limitation, or modification of the business relationship of Seller
with any customer or group of customers material to the Business, taken as a
whole, or with any supplier or group of suppliers material to the Business,
taken as a whole, including in each case as a result of the transactions
contemplated in the Agreement or the Seller Ancillary Agreements.

          4.1.22.  Product Warranties. Except as set forth in Schedule 4.1.22

such sale, assignment, transfer or other disposition of property does not, in

Buyer a listing of all capital expenditures for such month.

     5.2.  Inspection.  Subject to that certain letter agreement dated December

through its officers, employees, counsel, consultants, accountants, lenders,
investors, and other representatives, full access to Seller's premises, assets,
employees, books, and records (including, without limitation, tax records)
relating to the Assets or the Business, and shall instruct Seller's officers,
employees, counsel, consultants, accountants, actuaries, and other
representatives to cooperate in all reasonable respects with Buyer and its
representatives in its investigation of the Business and the Assets. Buyer shall
conduct its investigation upon reasonable notice to Seller, during Seller's

business or contravene any agreements. No investigation made by Buyer or its
representatives shall affect any representations or warranties of Seller under
this Agreement or any Seller Ancillary Agreements. Seller shall make all of its
real estate records relating to the Business available to Buyer for the purpose

relating to the Assets or the Business in accordance with Seller's record
retention policy as currently in effect. For six (6) years after the Closing
Date, neither Seller nor Buyer shall dispose, or permit the disposal, of any
books and records pertaining to the Business without first giving thirty (30)
days' prior written notice to the other Party offering to surrender the same to
such other Party at such other Party's expense. Each Party shall have reasonable
access to such books and records.

proceedings.

<PAGE>
 
           5.4.3.  GST.  Subject to payment of out-of-pocket costs by Seller,
Buyer will (or will cause an assignee to) register under Part IX of the Excise
Tax Act, R.S.O. 1985, CE-15 (Canada), and the Parties will cooperate in filing
all necessary returns and elections thereunder to eliminate or minimize the
payment of taxes thereunder.

     5.5.  Bulk Sales Compliance.  Seller shall not be required to comply with
the notice and other requirements of the bulk sales provision of the Uniform
Commercial Code (or the Canadian equivalent), as in effect in any state or
province having jurisdiction over the transactions contemplated by this
Agreement.

     5.6.  Consents.
           --------   

           5.6.1.  Seller shall act diligently and reasonably to obtain prior to
the Closing Date the Consents listed on Schedule 4.1.3 and the Consents
pertaining to the Assets requested by Buyer; provided, that Seller shall not
make any agreement or understanding affecting the Business or the Assets as a
condition for obtaining any such Consent except with the prior written consent
of Buyer.


           5.6.2.  Without limiting the generality of the foregoing, Seller and
Buyer will file or will cause to be filed, as promptly as possible and in no
event later than two (2) days after the date hereof, with the United States
Federal Trade Commission ("FTC") and the Antitrust Division of the United States
Department of Justice ("DOJ") pursuant to the HSR Act any notification and
report forms and related materials required by the HSR Act, and request early
termination of the waiting period required by the HSR Act. Seller and Buyer
shall furnish to each other such necessary information and reasonable assistance
as the other may request in connection with its preparation of any filing or
submission which is necessary under the HSR Act. Seller and Buyer shall each
keep the other apprised of the status of any inquiry or request for additional
information or documentation made by any governmental authority and shall comply
promptly with any such inquiry or request. Each Party warrants that all such
filings by it will be, as of the date filed, true and accurate and in accordance
with the requirements of the HSR Act. Buyer and Seller shall each use their best
efforts to achieve an expeditious closing of the transaction including, but not
limited to, attempting to avoid a Second Request under the HSR Act by meeting
with the FTC or DOJ as soon as practicable, responding promptly to requests for
additional information and negotiating in good faith a consent order or other
resolution with the FTC or DOJ consistent with the provisions of this Agreement.
Buyer and Seller, based on their respective independent analyses, believe that
there are no antitrust issues requiring any relief given the nature and extent
of competition in the agricultural input distribution business. Notwithstanding
the foregoing, to facilitate an expeditious closing, Buyer agrees that, if
reasonably requested by the DOJ or FTC: (1) Buyer will make good faith efforts
to sell, prior to or shortly after closing, any Overlap Facilities (defined as
either a Buyer owned facility or facility of the Business located within twenty
(20) miles of each other) to purchasers acceptable to the FTC or DOJ; (2) Buyer
will operate all remaining facilities acquired from Seller until at least
December 1, 1999; (3) Buyer will not sell or otherwise dispose of any of these
remaining facilities without giving thirty (30) days' prior written notice to
the FTC or DOJ before the completion of the sale or other disposition of any
facility acquired from Seller; and (4) Buyer will enter into a consent order
consistent with the provisions of this Agreement. As used

                                     -39-
<PAGE>
 
in this Section 5.6.2 "best efforts" does not include any obligation to divest
any properties or not to divest any properties, to hold properties separate or
to provide notice, except to the extent provided in the previous sentence. Buyer
and Seller shall each use their best efforts to oppose any injunction or the
enactment, entry, enforcement, or promulgation of any statute, rule, order, or
decree that would restrain or prohibit the transactions contemplated by this
Agreement. Buyer and Seller will agree in good faith upon the book value of the
fixed assets of each Overlap Facility required to be sold. Buyer and Seller
agree to cooperate with each other and to use their respective best efforts to
identify potential purchasers and to maximize the sales value for each Overlap
Facility required to be sold. Seller agrees to pay Buyer fifty percent (50%) of
the cumulative shortfall, if any, between the proceeds of the sale of the fixed
assets of any Overlap Facilities (net of reasonable out-of-pocket third party
sales costs) and their book value. Any such payment shall be made by Seller to
Buyer within seven (7) days after the closing of the sale of each of any Overlap
Facilities required to be sold and receipt by Seller of a copy of a bill of
sale, deed of conveyance, contract for deed, or other document evidencing a sale
and a certificate from Buyer setting forth the calculation of any cumulative
shortfall as to such store.

             5.6.3.  Seller shall use its best efforts to obtain the consents or
amendments referred to in Section 3.3.5, which shall include (if necessary) an
offer to use net proceeds from the sale of the Business to pay down or set aside
its obligations under one or more Credit Agreements and an offer to amend the
provisions of the Credit Agreements to reflect the disposition of the Business
to the extent reasonably requested by the lenders under the Credit Agreements
consistent with customary commercial lending practices for credits comparable to
the size and type provided under the Credit Agreements and for borrowers
comparable to the Seller and its subsidiaries taken as a whole (including
comparable credit ratings.)

             5.6.4. Seller shall use its best efforts to obtain the consent to
the assignment of its interest in Omnium, LLC to Buyer; provided, Seller shall
not be required to pay cash or any other consideration for such consent.

     5.7.    Insurance. Seller has advised Buyer that Seller has group insurance
the premiums on which may be retroactively adjusted after Closing depending upon
claims experience and for which additional premiums may be payable for periods
prior to the Closing Date. Seller shall pay such additional premium, if any,
when and as due, and Seller shall not make any claim against Buyer for
indemnification with respect to the same.

     5.8.    Assumption Agreement. On or prior to the Closing Date, to the
extent provided in Schedule 5.8, Seller and Seller's Affiliates shall assign to
Buyer their rights under the agreements listed in Schedule 5.8 and Buyer shall
assume Seller's and Seller's Affiliates' obligations under such agreements
pursuant to the Bill of Sale, Assignment, and Assumption Agreement. From the
date of this Agreement to the Closing Date, Seller shall use its good faith
reasonable efforts to enter into such agreements and other arrangements
(including, without limitation, sublicenses and subleases) with Buyer as are
necessary to ensure that Buyer has the right to receive benefits under the
agreements listed in Schedule 5.8 that are the same as the benefits the Business
received under such agreements prior to the Closing.

     5.9.    Notice of Developments. From the date of this Agreement through the
Closing Date, each Party shall give prompt written notice to the other Party of
(A) any claim, complaint,

                                      -40-
<PAGE>
 
demand, action, suit, proceeding, hearing, or investigation that shall be
threatened against it to restrain, prohibit, or otherwise challenge the legality
of any of the transactions contemplated by this Agreement, (B) any claim,
complaint, demand, action, suit, proceeding, hearing, or investigation that may
be threatened, brought, asserted, or commenced against Seller which would have
been listed in Schedule 4.1.10 if such claim, action, suit, proceeding, or
investigation had arisen prior to the date hereof, (C) any Material Adverse
Change, (D) any notice or other communication from any third Person alleging
that the Consent of such third Person is or may be required in connection with
the transactions contemplated by this Agreement, any Seller Ancillary Agreement,
or any Buyer Ancillary Agreement, (D) any breach or any false or inaccurate
statement of any of the representations and warranties of Seller hereunder or
any failure of Seller to comply with the covenants, conditions, or agreements to
be complied with by Seller hereunder, and (E) any material default under any
Material Agreement or any event which, with notice or lapse of time or both,
would become such a default on or prior to the Closing Date and of which Seller
has knowledge. No disclosure by any Party pursuant to this Section 5.9, however,
shall be deemed to amend or supplement any Schedule, to prevent or cure any
misrepresentation or breach of warranty, or to limit or otherwise affect the
remedies available to Buyer under this Agreement or any Seller Ancillary
Agreements.

     5.10.   Updating of Schedules. On the Closing Date, Seller shall deliver to
Buyer updated Schedules to reflect any material change in the Schedules
delivered to Buyer pursuant to this Agreement.

     5.11.   Financial Statements. Until the Closing, on or before the 21st day
of each month, Seller shall deliver to Buyer unaudited consolidated financial
statements of the Business as at and for the monthly period ending the last day
of the preceding month, which shall include a balance sheet and statements of
income and cash flow. At the time that such monthly financial statements are
delivered to Buyer, Seller by such delivery shall be deemed to have made the
representations and warranties to Buyer with respect to such monthly financial
statements set forth in Section 4.1.4.

     5.12.   Permits and Licenses. Prior to the Closing Date, Seller shall use
reasonable efforts to have in full force and effect as of the Closing Date all
permits, licenses, and other authorizations required by any Governmental Body to
be obtained prior to Closing and that are necessary to operate the Business,
taken as a whole.

     5.13.   Collection of Receivables. All cash, checks, or other proceeds
received by Seller or its banks after the Closing Date that relate to the
Receivables shall be paid to Buyer promptly and in any event within five (5)
business days after receipt by Seller, which payments shall be accompanied by a
statement identifying the payee, the amount of the payment, and the invoice
number related thereto. Seller shall instruct its banks to forthwith remit to
Buyer all amounts received by such banks with respect to the Receivables. Buyer
shall have the right to endorse the name of Seller on any such check or proceeds
(whether received directly by Buyer or received from Seller or its banks) and
shall deposit such checks and other proceeds in bank accounts maintained in
Buyer's name. From and after the Closing Date, the Parties shall cooperate with,
and provide reasonable assistance to, each other with respect to the collection
of receivables arising both before and after the Closing Date. Buyer shall
promptly remit to Seller any payments received by it belonging to Seller or any
cash remitted by Seller to Buyer and

                                      -41-
<PAGE>
 
representing the payment of a subsequently dishonored check upon presentation of
such dishonored check. Seller shall promptly remit to Buyer any payments
received by it belonging to Buyer.

     5.14.   Exclusivity. From the date of this Agreement through the Closing
Date or until the termination of this Agreement, none of Seller, any Affiliate
of Seller, or any Person acting on Seller's behalf shall, except as otherwise
permitted by this Agreement, directly or indirectly, (A) knowingly solicit or
encourage any inquiry or proposal for, or enter into any discussions or
negotiations with respect to, the acquisition of any of the assets held for use
primarily in connection with, necessary for the conduct primarily of, or
otherwise material primarily to, the Business or the merger or consolidation of
Seller (a "Third Party Offer") or (B) furnish or caused to be furnished any
financial information or any confidential or non-public information relating
primarily to the Business or afford access primarily to the properties, books,
or records of the Business to any Person (other than Buyer and its agents and
representatives), except in the Ordinary Course of Business or pursuant to any
Requirement of Law and in any event if not in the Ordinary Course of Business
after prior written notice to Buyer; provided, however, nothing is to preclude
discussions, negotiations, furnishing information or entering into agreements
with respect of the entirety of Seller or the sale of Minorco's shares.

     5.15.   Further Assurances. Each Party shall, at any time and from time to
time after the Closing, and without further consideration, take such actions,
and shall cause its Affiliates or use its best efforts to cause others to take
such action, and execute, acknowledge, and deliver, and shall cause its
Affiliates or use its best efforts to cause others to execute, acknowledge, and
deliver, all instruments, documents, transfers, conveyances, and assurances as
may be reasonably requested by the other Party or as may be otherwise reasonably
necessary for the better confirming, transferring, assigning, and delivering to
Buyer the Assets to be sold by Seller to Buyer hereunder, for evidencing Buyer's
assumption of the Assumed Liabilities, and for reducing to the possession of
Seller any of the Assets not in Seller's possession at the Closing Date.

     5.16.   Litigation Support. At any time after the Closing, in the event and
for so long as any Party actively is contesting or defending against any action,
suit, proceeding, hearing, investigation, complaint, claim, or demand in
connection with (A) any of the transactions contemplated under this Agreement or
(B) any fact, situation, circumstance, status, condition, activity, practice,
plan, occurrence, event, incident, action, failure to act, or transaction on or
prior to the Closing Date involving the Business or the Assets, the other Party
shall cooperate with such Party or its counsel in the defense or contest, make
reasonably available its personnel (other than in-house legal personnel unless
reasonably compensated for such services), and provide such testimony and access
to its books and records as shall be reasonably necessary in connection with the
defense or contest, all at the sole reasonable cost and expense (which shall
include reasonable compensation for time expended in cooperating) of the
contesting or defending Party (unless the contesting or defending Party is
entitled to indemnification therefor under Article 6 of this Agreement).

     5.17.  Environmental Investigation. Seller shall allow Buyer and its
representatives and agents access to the Property and the Business, upon
reasonable notice to Seller's environmental supervisor and, at all reasonable
times prior to Closing and without charge, for the purpose of conducting the
such environmental investigations as Buyer may desire. Seller shall allow Buyer

                                      -42-
<PAGE>
 
and its representatives and agents access to all plans and specifications for
the improvements on the Property and all current and historical maintenance
records, licenses, permits, reports, certificates, correspondence with
governmental authorities, or other items relating to the construction,
operation, or environmental assessment or audit of the Property or the Business.
Seller shall make available, for the purpose of interviews with Buyer and its
representatives and agents, such employees and representatives of the Business
as may have knowledge useful in the environmental assessment or audit of the
Property and the Business. Seller shall not object to, or interfere with,
interviews by Buyer and its representatives and agents with past and present
employees, occupants, or owners of the Property or the Business, and past and
present owners and occupants of property in the vicinity of the Property. Seller
shall have the right to observe any such investigation.

     5.18    Employees and Employee Benefits.

             5.18.1.  Buyer shall offer to hire, on the Closing Date, subject to
completion of an employment application and a Form I-9, and the truthfulness
thereof, and any drug testing to the extent required by a Requirement of Law,
the following employees of Seller at the close of business on the Closing Date:
(i) all employees of the Business located at retail sites or area or region
administrative offices, (ii) all employees of the Business located at the
Southern Division headquarters, (iii) Seller's employees listed on Schedule
5.18.1 and (iv) any other employees mutually agreed by Buyer and Seller. An
employee to whom an offer of employment is made by Buyer and who accepts such
offer shall become an employee of Buyer on the day such employee reports to work
for Buyer (the "Transferred Employees"); an employee to whom an offer of
employment is made, but who is unable to report to work for Buyer as of the
close of business on the Closing Date due to illness, injury, or other reason
shall remain an employee of Seller until such employee reports to work for Buyer
or such employee's employment by Seller otherwise terminates. Seller shall, and
shall cause its Affiliates to, use reasonable efforts to cause the employees
described in the first sentence of this Section 5.18.1 to make available their
employment services to Buyer

             5.18.2. Except for those employees who have entered into employment
agreements with Buyer concurrently herewith, the initial base pay of each
Transferred Employee shall be the same as the base pay of such Transferred
Employee on the Closing Date. Each Transferred Employee shall be eligible for
the benefits listed on Schedule 5.18.2 subject to satisfaction of all
qualifications. Buyer agrees that it will continue the following incentive plans
for the benefit of Transferred Employees: Terra Industries Incentive Award
Program for Officers & Key Employees, Terra Distribution Division 1999 Key
Employee Incentive Award Program, Terra Distribution Division 1999 Area
Incentive Award Program, Terra Distribution Division 1999 Region Manager
Incentive Award Program, and Terra Distribution Division 1999 Professional
Products Sales Force Incentive Award Program. For those Transferred Employees
covered by the Terra Industries Incentive Award Program for Officers and Key
Employees, the award formula will be modified to provide that 100% of the target
incentive can be achieved without reference to components that do not relate
solely to the Business, unless Buyer and the Transferred Employee agree
otherwise. All other terms of employment of each offer to the Employees shall be
determined by Buyer in its sole discretion, and nothing herein shall constitute
an agreement to assume or be bound by any employment agreement or employee plan,
or previous or existing collective bargaining agreement between Seller and any
representative of the

                                      -43-
<PAGE>
 
Employees or a guaranty that any Employee to whom an offer of employment may be
made shall be entitled to remain in the employment of Buyer for any specified
period of time. To the contrary, employment with the Buyer will be employment at
will. Buyer shall have the right to terminate the employment of any Transferred
Employee at any time, for any reason, and to change the terms of such
Transferred Employee's wages, salaries, and benefits consistent with law,
subject to the Buyer's obligation to such Transferred Employee under the
benefits listed on Schedule 5.18.2 or by a Requirement of Law.

     Seller shall use reasonable efforts to arrange for the continued coverage,
at Buyer's expense, of the Transferred Employees under Seller's group welfare
plans through December 31, 1999, subject to the terms hereof. Such continued
coverage shall be provided only if Seller's group welfare plan service providers
agree to set up separate accounting for the experience, claims, administrative
expenses, and premiums attributable to the Transferred Employees on and after
the Closing Date. Buyer shall be responsible for and shall pay all the costs of
such separate accounting. If Seller's group welfare plan service providers shall
agree to bill Buyer directly for such costs, Buyer shall pay such amounts
directly to such service providers. If Seller's group welfare plan service
providers do not so agree, Seller shall pay all invoices or bills and Buyer
shall reimburse Seller within five (5) business days after receipt of an
accounting for such payments, not more often than semi-monthly.

     Buyer shall cause all the benefits listed on Schedule 5.18.2 to take into
account all periods of employment of Transferred Employees with Seller prior to
the Closing Date as if it were employment with Buyer for all purposes under such
benefits except for the purposes of determining the amount of a Transferred
Employee's accrued benefit under any plan that is a defined benefit plan. Buyer
also shall cause its plans that are welfare plans to waive restrictions on
coverage, such as pre-existing conditions, with respect to Transferred Employees
and to take into account any amounts paid by Transferred Employees under
comparable plans of Seller as if such amounts were incurred under the comparable
plans of Buyer for purposes of determining deductibles, maximum out-of-pocket
limitations and similar items.

             5.18.3. Seller shall pay the amount of salaries, wages, and
benefits earned through the Closing Date by each Transferred Employee on
Seller's next regularly scheduled pay date for that Employee. With respect to
Transferred Employees, Seller shall pay to Buyer at Closing (or there shall be
reflected as a current liability on the Closing Date Balance Sheet) an amount
equivalent to such Transferred Employees' earned and accrued (but unpaid)
vacation and sick pay up to the Closing Date.

             5.18.4. Neither Buyer nor any of its Affiliates shall have any
liability with respect to any Employee or any Plan, or any dispute or claim
thereof or related thereto, except to the extent expressly provided in this
Section 5.18. Subject to Buyer's reimbursement obligation provided in this
Section 5.18, from and after the Closing, Seller shall remain solely responsible
for all salaries, wages, benefits, severance arrangements, liabilities
(including, but not limited to legal or equitable claims and disputes of any
kind, and any damage penalties, costs or fees arising therefrom), and all other
compensation and terms of employment for services rendered to Seller for (A)
each Transferred Employee accruing prior to the date such Employee becomes an
employee of Buyer and (B) each Employee who does not become a Transferred
Employee accruing at any time.

                                      -44-
<PAGE>
 
             5.18.5. From and after the Closing, Seller shall remain solely
responsible for all liabilities relating to, arising out of, or resulting from
(i) the requirements of Section 4980B of the Code to provide continuation of
health care coverage under any of its Plans in respect of (A) the Employees,
other than the Transferred Employees and their covered beneficiaries and
dependents, and (B) the Transferred Employees, to the extent related to a
qualifying event occurring on or before the Closing Date, and (ii) all claims
for workers' compensation benefits arising in connection with any occupational
injury or disease occurring on or prior to the Closing Date. Buyer shall be
responsible for all liabilities relating to, arising out of, or resulting from
the requirements of Section 4980B of the Code arising after the Closing Date
with respect to any Transferred Employee (or their spouse or dependents).

             5.18.6.

                     5.18.6.1 Employees listed or categorized in Schedule
5.18.6(a) (the "Non-Transferred Employees"), whose employment with Seller is
terminated within seven (7) business days after the Closing Date, shall receive
the severance and retention payments set forth in Schedule 5.18.6(b). Non-U.S.
Employees of Seller who have been offered employment with Buyer, but for
whatever reason do not become Transferred Employees, shall receive severance or
other payments required by any Requirement of Law. Seller shall make those
payments to the Non-Transferred Employees and the non U.S. terminated Employees
as soon as practicable after dates of their respective terminations of
employment and consistent with the required payment obligations.

                     5.18.6.2 Employees listed or categorized in Schedule
5.18.6(c) (the "Transition Employees"), whose employment with Seller is
terminated within seven (7) business days after the completion of the transition
services to be provided by such employee shall receive the severance and
retention payments set forth in Schedule 5.18.6(b). Seller shall make those
payments to the Transition Employees as soon as practicable after dates of their
respective terminations of employment and consistent with the required payment
obligations.

                     5.18.6.3 Buyer shall make the severance and retention
payments to Transferred Employees in the amounts established in, and according
to the terms and conditions of, the "Transferred Employee Severance and
Retention Payment Plan" contained in Schedule 5.18.6(d) ; provided, however,
that in the case of non-U.S. Transferred Employees Buyer shall make such
severance or other payments required by any Requirement of Law.

             5.18.7. Buyer's financial responsibility to Seller for any
severance or retention payment made by Seller to an employee under Section
5.18.6, whether the employee is a Non-Transferred Employee or a Transition
Employee, is limited as set forth below (and for purposes of calculating
Seller's limited reimbursement obligations to Buyer as contemplated in Section
5.18.8, Buyer's standard for severance and retention obligations for Transferred
Employees shall be as follows):

                     5.18.7.1 Severance Payment - A maximum payment equivalent
to (a) twenty-six (26) weeks base pay for any exempt employee, and (b) sixteen
(16) weeks base pay for non-exempt employees.

                                      -45-
<PAGE>
 
                   5.18.7.2   Retention Payment - Buyer shall have no financial
responsibility for any "retention payment" as that term is described in Schedule
5.18.6(b) (payment to Non-Transferred Employees) or in the Transferred Employee
Severance/Retention Payment Plan contained in Schedule 5.18.6(d) (payment to
Transferred and Transition Employees).

          5.18.8

                   5.18.8.1.  Solely in respect of Transferred Employees and
subject to the limitations set forth in Section 5.18.8.3, Seller shall reimburse
Buyer for any (i) severance payment in accordance with Schedule 5.18.6(d) in
excess of Buyer's limitation on severance payments set forth in Section 5.18.7,
(ii) any retention payment, and (iii) any reimbursement of a shortfall in "Base
Pay" (as that term is defined in the Transferred Employee Severance and
Retention Plan) received from a "Successor" (as that term is defined in the
Transferred Employee Severance and Retention Plan) as compared to Base Pay paid
by Buyer plus applicable employment related taxes. Buyer shall submit written
requests for installments of not less than $500,000 each (other than the last
such installment). Seller shall make such reimbursement payment within five (5)
business days after Seller's receipt of reasonable documentation establishing
that Buyer has made qualifying payments under the Transferred Employee Severance
and Retention Plan sufficient in amount to entitle Buyer to such
installments(s). There is no limitation as to the frequency with which Seller
may be required to make the installment reimbursement payments described in this
paragraph.

                   5.18.8.2   Solely with respect to Non-Transferred Employees,
non-U.S. Terminated Employees and Transition Employees, Buyer shall reimburse
Seller for the amount of payments made by Seller pursuant to Sections 5.18.6.1
and 5.18.6.2, up to the maximum per employee obligation for which Buyer is
obligated under Section 5.18.7, plus applicable employment related taxes. Seller
shall submit written requests for payments hereunder in installments of not less
than $100,000 (other than the last installment). Buyer shall make such
reimbursement payment within five (5) business after receipt of request from
Seller. Seller agrees to provide such documentation as Buyer may reasonably
request to confirm that such payments have been made.

                   5.18.8.3   In no event shall the sum of (a) payments made by
Seller pursuant to Sections 5.18.6.1 and 5.18.6.2 (net of Buyer's reimbursement
payments pursuant to Section 5.18.8.2) and (b) Seller's reimbursement payments
pursuant to Section 5.18.8.1 exceed a total amount of five million six hundred
twenty thousand dollars ($5,620,000). This limitation on Seller's obligation to
Buyer shall in no way limit Buyer's obligations to Transferred Employees under
Section 5.18.6.3.

          5.18.9   With respect to those employees listed on Schedule 5.18.9 and
notwithstanding any other provisions set forth in Section 5.18, Buyer shall
either: (a) enter into employment or severance/retention agreements which shall
contain provisions ("Release Provisions") by which Seller is released of its
obligations under its retention agreements ("Retention Agreements") with
employees; or (b) reimburse Seller in full for any expense it becomes obligated
to make under such Retention Agreements, with respect to any employee who is not
offered employment or does not maintain employment for a period of 18 months
with

                                     -46-
<PAGE>
 
Buyer with (1) the same base pay and bonus/incentive potential as of Closing
Date; (2) employee benefits as set forth in Schedule 5.18.2; (3) a work site not
more than 50 miles from the employee's current work site and (4) no substantial
change in responsibilities. It is understood that Seller may amend the Retention
Agreements prior to the Closing Date to provide for the benefits contemplated
herein to become triggered on a basis consistent with the preceding sentence. It
is further understood that the benefits and payments made to employees covered
under this section are in lieu of any payments under Section 5.18.6.

     5.19  Inventories.  Seller shall sell to the Business as of the close of
business on the Closing Date all fertilizer owned by Seller and its Affiliates
stored at any Property of the Business, and the Final Statement shall reflect a
payable for such sale. All accounts payable on the Final Statement arising from
the sale by Seller or any of its Affiliates of goods or services to the Business
shall be deemed to be on same terms as Seller has used in its operation of the
Business and at least as favorable as Seller customarily offers to third-party
customers having the significance of the Business.

     5.20   Ancillary Agreements.  Subject to the satisfaction of the conditions
of Sections 3.1 and 3.3, Seller agrees to enter into the Seller Ancillary
Agreements on the Closing Date, and subject to the satisfaction of the
conditions of Sections 3.1 and 3.2, Buyer agrees to enter into the Buyer
Ancillary Agreements on the Closing Date. Buyer and Seller shall negotiate in
good faith the form and substance of the Transition Services Agreement and
Sublease on customary terms and conditions and based on allocation of actual
costs for providing those services listed on Exhibit H until December 31, 1999.
The Sublease shall have a duration of two years, shall be for between one and
one-half and three floors in Terra Center (or the equivalent square footage in
Jackson Plaza or a combination thereof) and shall include office furniture,
terminals, and networking.

     5.21.  Insurance.  To the extent that Buyer may suffer damage to the Assets
or may be subjected to any third party claims for which it may be the
beneficiary of insurance policies maintained by Seller on or prior to the
Closing Date, upon the reasonable request of Buyer, Seller shall cooperate, at
Buyer's expense, with Buyer in pursuing coverage under such policies, provided,
however, that Seller shall not be required to take any action that would
jeopardize or otherwise diminish its insurance coverage.

                                   ARTICLE 6

          (F)  any product liabilities with respect to products manufactured or
sold by Seller prior to the Closing Date;

in effect in any state having jurisdiction over the transactions contemplated in
this Agreement; and

          (H)  the Liens referred to in Section 2.9.

Other than Losses resulting from a breach of Section 4.1.8, Seller shall be

inaccuracy of any representation of Seller contained in this Agreement, any
Seller Ancillary Agreement or any certificate delivered by or on behalf of
Seller pursuant hereto or thereto exceeding $1,000,000 in the aggregate and not
exceeding 50% of the Purchase Price. The indemnification provided for in this
Section 6.1 shall terminate two (2) years after the Closing Date (and no claims
shall be made by any Buyer Group Member under this Section 6.1 thereafter),
except that the indemnification by Seller shall continue as to:

               (i)    the representations and warranties set forth in Sections
4.1.1, 4.1.2, 4.1.8, and 4.1.24, as to all of which no time limitation shall
apply forever;

statutory periods of limitations, giving effect to any waiver, mitigation, or
extension thereof;

               (iii)  any Loss of which any Buyer Group Member has notified
Seller in accordance with the requirements of Section 6.4 on or prior to the
date such indemnification would otherwise terminate in accordance with this
Section 6.1, as to which the obligation of Seller shall continue until the
liability of Seller shall have been determined pursuant to this Article 6, and
Seller shall have reimbursed all Buyer Group Members for the full amount of such
Losses in accordance with this Article 6; and

               (iv)   the indemnification provided for in clauses (C), (D), (E),
(F), (G), and (H) of this Section 6.1, which shall survive until the expiration
of the applicable statutory periods of limitations, giving effect to any waiver,
investigation, or extension thereof.

     6.2.  Indemnification by Buyer.  Subject to the provisions of this Article
6, Buyer covenants and agrees to defend, indemnify, and hold harmless each
Seller Group Member from and against, and pay or reimburse each Seller Group
Member for, all Losses incurred by such Seller Group Member relating to, arising
out of, or resulting from:

           (A)  any breach by Buyer of any of its covenants or agreements in
this Agreement where Seller's claim is solely for monetary damages; and

           (B)  any breach of any warranty or any inaccuracy of any

Buyer shall be responsible only for Losses resulting from any breach of any
warranty or any inaccuracy of any representation of Buyer contained in this
Agreement, any Seller Ancillary Agreement or any certificate delivered by or on
behalf of Seller pursuant hereto or thereto exceeding $1,000,000 in the
aggregate and not exceeding 50% of the Purchase Price. The indemnification
provided for in this Section 6.2 shall terminate two (2) years after the Closing
Date (and no claims shall be made by any Seller Group Member under this Section
6.2 thereafter), except that the indemnification by Buyer shall continue as to:

                (i)    the representations and warranties set forth in Sections
4.2.1, 4.2.2, and 4.2.5; as to all of which no time limitation shall apply;

any waiver, mitigation, or extension thereof; and

                (iii)  any Loss of which Seller has notified Buyer in accordance

as to which the obligation of Buyer shall continue until the liability of Buyer
shall have been determined pursuant to this Article 6, and Buyer shall have
reimbursed all Buyer Group Members for the full amount of such Losses in
accordance with this Article 6.

     6.3  Survival of Representations, Warranties, Covenants, and Obligations.  
The representations, warranties, covenants and obligations contained in this
Agreement shall survive the execution and delivery of this Agreement, any
examination by or on behalf of the Parties, and the consummation of the
transactions contemplated herein; provided, however, that, notwithstanding the
foregoing (A) the representations and warranties contained in Sections 4.1.1,
4.1.2, 4.1.8, 4.1.24, 4.2.1, 4.2.2 and 4.2.5 shall survive without limitation,
(B) the representations, warranties, covenants, and obligations contained in
Sections 4.1.14, 5.3, 5.4, 5.7, 5.8, 5.13, 5.15, 5.16, 5.18, 6.6 and 8.2 shall
survive until the expiration of the applicable statutory periods of limitations,
giving effect to any waiver, mitigation, or extension thereof, (C) the
representations and warranties contained in Article 4 and 5 and not otherwise
referred to in clauses (A) and (B) of this Section 6.3)) shall survive until two
(2) years after the Closing Date, (D) any covenant to be performed after the
Closing Date (other than the covenants referred to in

                                     -49-
<PAGE>
 
clause (B) of this Section 6.3 shall survive until such date as such covenants
are fully performed, and (E) any other representations, warranties, covenants,
and obligations contained in this Agreement shall terminate on the sixth (6th)
anniversary of the Closing Date. Except as otherwise provided herein, no claim
shall be made under this Article 6 or any other provision of this Agreement or
otherwise for the breach of any representation, warranty, covenant, or
obligation contained in this Agreement, or under any certificate delivered with
respect hereto, after the date on which such representation, warranty, covenant,
or obligation terminates as set forth in this Section 6.3. Buyer and Seller each
agree that the indemnification provided by Sections 6.1 and 6.2, respectively,
is its sole and exclusive remedy for any Loss within the coverage provided by
such Sections; provided, however, except as specifically provided in Sections
6.1 and 6.2, the Parties shall have all remedies provided by law for breach of
covenants on or after the Closing Date, including specific performance and other
equitable relief.

     6.4.  Notice of Claims.  Any Buyer Group Member or any Seller Group Member
seeking indemnification under this Agreement (the "Indemnitee") shall give to
the Party obligated to provide indemnification to such Indemnitee (the
"Indemnitor") a notice (a "Claim Notice"). Such Claim Notice shall be in a
writing signed by the Indemnitee, or if the Indemnitee is a corporation, an
officer thereof, setting forth: (A) the facts or events, in reasonable detail,
which indicate that it has incurred such liability; (B) the Section or Sections
of this Agreement (in addition to those under Article 6 of this Agreement) under
which the Indemnitee has incurred such liability; (C) the amount of such
liability or, in the case of third party claims, the Indemnitee's good faith
estimate of the reasonably foreseeable maximum amount of its claim for
indemnification; and (D) the method of computation of the amount of such
liability, all of which information shall be promptly amended by the Indemnitee
when its knowledge of the facts or events and any resulting liability so
warrant; provided, that a Claim Notice in respect of any action at law or suit
in equity by or against a third Person as to which indemnification will be
sought shall be given promptly after the action or suit is commenced; and
provided further that failure to give such notice shall not relieve the
Indemnitor of its indemnification obligations hereunder except to the extent
that such failure results in a failure of actual notice to the Indemnitor and
the Indemnitor is materially damaged as a result of such failure.

     6.5.  Matters Involving Third Parties.
           -------------------------------   

           6.5.1.  Subject to Section 6.5.2, the Indemnitee shall have the right
to conduct and control, through not more than one counsel of its choosing
reasonably acceptable to Indemnitor, the defense, compromise, or settlement of
any third Person claim, action, or suit against such Indemnitee as to which
indemnification will be sought by any Indemnitee from any Indemnitor hereunder,
and in any such case the Indemnitor shall cooperate in connection therewith and
shall furnish such records, information, and testimony and attend such
conferences, discovery proceedings, hearings, trials, and appeals as may be
reasonably requested by the Indemnitee in connection therewith; provided, that
the Indemnitor may participate, through counsel chosen by it and at its own
expense, in the defense of any such claim, action, or suit as to which the
Indemnitee has so elected to conduct and control the defense thereof; and
provided, further, that the Indemnitee shall not, without the prior written
consent of the Indemnitor (which written consent shall not be unreasonably
withheld), pay, compromise or settle any such claim, action, or suit, except
that no such consent shall be required if, following a written request from the
Indemnitee, the Indemnitor shall fail, within fourteen (14) days after the
making of such request,

                                     -50-
<PAGE>
 
to acknowledge and agree in writing that, if such claim, action, or suit shall
be adversely determined, such Indemnitor has an obligation to provide
indemnification hereunder to such Indemnitee.

           6.5.2.  If any third Person claim, action, or suit against any
Indemnitee is solely for money damages or, where Seller is the Indemnitor, will
have no continuing effect in any material respect on the assets, properties,
operations, or business of the Business, then the Indemnitor shall have the
right to conduct and control, through counsel of its choosing, the defense,
compromise, or settlement of any such third Person claim, action, or suit
against such Indemnitee as to which indemnification will be sought by any
Indemnitee from any Indemnitor hereunder if the Indemnitor has acknowledged and
agreed in writing that, if the same is adversely determined, the Indemnitor has
an obligation to provide indemnification to the Indemnitee in respect thereof,
and in any such case the Indemnitee shall cooperate in connection therewith and
shall furnish such records, information, and testimony and attend such
conferences, discovery proceedings, hearings, trials, and appeals as may be
reasonably requested by the Indemnitor in connection therewith; provided, that
the Indemnitee may participate, through counsel chosen by it and at its own
expense, in the defense of any such claim, action, or suit as to which the
Indemnitor has so elected to conduct and control the defense thereof.
Notwithstanding the foregoing, the Indemnitee shall have the right to pay,
settle, or compromise any such claim, action, or suit, provided that in such
event the Indemnitee shall waive any right to indemnity therefor hereunder and
further provide that any such payment, settlement or compromise would have no
continuing effect on Indemnitor.

     6.6.  Tax Indemnification.  Seller shall defend, indemnify, and hold
harmless Buyer and each Buyer Group Member from and against all Taxes except
those specifically assumed by Buyer and all Transfer Taxes. If any claim or
demand is asserted in writing against an Indemnitee hereunder, the Indemnitee
shall notify the Indemnitor of such claim or demand within thirty (30) days of
receipt thereof, and the Indemnitor shall (at the sole expense of such
Indemnitor) to the extent possible under applicable law, have the right to
control the defense, compromise, or settlement thereof; provided, however, that
Seller shall not compromise or settle any such claim or benefit in a manner
which is materially adverse to the Buyer, without the consent of Buyer; and the
Indemnitee shall cooperate fully in such defense as and to the extent reasonably
requested by the Indemnitor. Such cooperation shall include the retention and
(upon the Indemnitor's request) the provision to the Indemnitor of records and
information which are reasonably relevant to such claim or demand and making
employees available on a mutually convenient basis to provide additional
information and explanation of any material provided hereunder. An Indemnitor
shall not have any liability hereunder with respect to, or obligation to
indemnify against, any liability for any Tax resulting from a claim or demand
the defense, compromise, or settlement of which it was not offered the
opportunity to control as provided hereunder. Each Party's right under this
Section 6.6 shall survive until the expiration of any applicable statute of
limitations, as such statute of limitations may be extended by the Indemnitee.

Buyer or (B) if the Closing shall not have occurred on or before August 31, 1999

shall relieve any Party from liability for its breach of this Agreement.

                                   ARTICLE 8
                                 MISCELLANEOUS

their respective Affiliates shall not issue any press release or make any other
public announcement relating the subject matter of this Agreement, the Seller
Ancillary Agreements, or the Buyer Ancillary Agreements without the prior
written consent of the other Party; provided, however, that any Party may make
public announcements which such Party determines, upon consultation with such
Party's outside legal counsel, is required by applicable laws or regulations or
the rules of any securities exchange on which such Party's securities are traded
and any Party may, after or

                                     -52-

concurrently with the first public disclosure consented to by the parties, make

and the Parties shall use their best efforts to cause mutually agreeable
announcements to be issued.

Party shall each bear its own costs, expenses, and fees (including fees and
expenses of attorneys and other professionals) in connection with this Agreement
and the transactions contemplated hereby, whether or not the transactions

     8.3.  "As Is" Condition. EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT,
SELLER MAKES NO REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO THE ASSETS
OR THE BUSINESS, INCLUDING, BUT NOT LIMITED TO, ANY WARRANTY OF MERCHANTABILITY
OR FITNESS FOR A PARTICULAR PURPOSE.

     8.4.  Notices. All notices, demands, claims, waivers, and other
communications hereunder shall be in writing. Any notice, demand, claim, waiver,

     Minneapolis, Minnesota 55402
     Attention:  William B. Payne

Any Party may send any notice, demand, claim, waiver, or other communication
hereunder to the intended recipient at the address set forth above using any
other means (including telecopy, telex, ordinary mail, or electronic mail), but
no such notice, demand, claim, waiver, or other communication shall be deemed to
have been duly given unless and until it actually is received by the intended
recipient. Any Party may change the address to which notices, requests, demands,
claims, and other communications hereunder are to be delivered by giving the
other Party notice in the manner herein set forth.

     8.5.  Severability. Whenever possible, each provision (including any
phrase, sentence, clause, section, or subsection) of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but in case any provision of this Agreement shall be held to be invalid,
illegal, or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such provision shall be ineffective to the extent, but only to the
extent, of such invalidity, illegality, or unenforceability in such jurisdiction
without invalidating the remainder of such invalid, illegal, or unenforceable
provision or any other provision hereof in such jurisdiction or any other
jurisdiction, unless such a construction would be unreasonable.

     8.6.  Amendments and Waivers. No modification, amendment, supplement, or
waiver of this Agreement shall be valid or binding unless made in writing and
signed by each Party. No course of dealing between the Parties shall be deemed
effective to modify or amend any part of this Agreement or any rights or
obligations of any Party under this Agreement. A written waiver shall be valid
or binding only as to the specific term or condition waived, and no written
waiver shall be deemed to be a continuing waiver unless specifically stated. The
waiver by a party of a breach or default under any provision of this Agreement
shall not be construed as a waiver of any other breach or default of any such
provision hereunder, and the failure by any party on one or more occasions to
enforce any provision of this Agreement or to exercise any right or privilege
hereunder shall not be construed as a waiver of any such provision, right, or
privilege hereunder.

     8.7.  Interpretations. The headings of the sections and subsections of this
Agreement are for the convenience of references only and do not form a part of
this Agreement and shall in no way affect the meaning or interpretation of this
Agreement. The Schedules, Exhibits, Buyer Ancillary Agreements, Seller Ancillary
Agreements, certificates, documents, and instruments referred to herein shall be
construed with and as an integral part of this Agreement to the same extent as
if they were set forth verbatim herein. The Parties have participated jointly in
the negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties, and no presumption or burden of proof
shall arise favoring or disfavoring any party by virtue of the authorship of any
provision of this Agreement.

     8.8.  Binding Effect and Beneficiaries. This Agreement shall be binding
upon and inure to the benefit of the Parties hereto and their heirs, successors,
and permitted assigns. The heirs, successors, and permitted assigns hereunder
shall include without limitation, in the case of Buyer, any permitted assignee
as well as the successors in interest to such permitted assignee (whether by
merger, liquidation (including successive mergers or liquidations), or
otherwise). Except as provided in Article 6 of this Agreement with respect to
indemnification of Buyer Group Members and Seller Group Members, this Agreement
shall not confer any right or remedy upon any Person other than the Parties and
their respective successors and permitted assigns.

     8.9.  Assignment. The rights and obligations of either Party under this
Agreement shall not be assignable by such Party prior to the Closing without the
written consent of the other Party, except that Buyer may assign its rights and
obligations hereunder, without the consent of Seller, to any Person (A) with or
into which Buyer may merge or consolidate, (B) to which Buyer may sell or
transfer all or substantially all of its assets, (C) of which Buyer is a general
partner, (D) which owns directly or indirectly 50% or more of the equity
investment and of the voting power of Buyer, (E) of which 50% or more of the
equity investment and of the voting power is owned directly or indirectly by, or
is under common ownership with, Buyer, (F) who is a lender to Buyer, or an
Affiliate of such lender, as security for obligations to such lender or
Affiliate in respect of the financing arrangements entered into in connection
with the transactions contemplated hereby and any refinancings, extensions,
refundings, or renewals thereof, (G) who is an Affiliate of Buyer, or (H) who is
a Buyer Group Member; provided, however, that (i) the assignee shall assume in
writing all of Buyer's obligations to Seller hereunder and (ii) Seller's
obligations under this Agreement shall be subject to the delivery by such
assignee, on or prior to the Closing Date, of a certificate signed on its behalf
containing representations and warranties similar to those made by Buyer in
Section 4.2 and an opinion of counsel reasonably acceptable to Seller with
respect to the assignee which is similar to the opinion with respect to Buyer
set forth in Exhibit C. In addition, Buyer may assign its right to acquire a
group of facilities to any Person described in clause (H) of the first sentence.
Following the Closing, either Party may assign any of its rights hereunder, but
no such assignment shall relieve it of its obligations hereunder.

     8.10.  Remedies. The rights and remedies provided in this Agreement are
cumulative and except as expressly provided herein are not exclusive of any
rights or remedies that any Party may otherwise have at law or in equity. The
rights and remedies of any Party based upon, arising out of, or otherwise in
respect of any inaccuracy or breach of any representation, warranty, covenant,
agreement, or obligation or failure to fulfill any condition shall in no way be
limited by the fact that the act, omission, occurrence, or other state of facts
upon which any claim of any such inaccuracy, breach, or failure is based may
also be the subject matter of any other representation, warranty, covenant,
agreement, obligation, or condition as to which there is no inaccuracy, breach,
or failure. The representations and warranties of Seller shall not be affected
or deemed waived by reason of any investigation made by or on behalf of Buyer
(including, without limitation, Buyer's advisors, consultants, or
representatives) or by reason of the fact that Buyer or any such advisor,
consultant, or representative knew or should have known that any such
representation or warranty is or might be inaccurate. Nothing herein shall
permit any double recovery for any loss.

     8.11.  Counterparts. The Parties may sign this Agreement in any number of
counterparts and on separate counterparts, each of which shall be deemed an
original and all of which together shall constitute one and the same instrument,
and which shall become binding when one or more counterparts have been signed by
each of the Parties hereto and delivered to each of Buyer and Seller.

     8.12.  Governing Law and Jurisdiction. This Agreement shall be governed by,
and construed in accordance with, the internal laws of the State of New York,
without giving effect to any choice or conflict of law provision or rule that
would cause the application of the laws of any jurisdiction other than the State
of New York.

     8.13.  Entire Agreement. This Agreement (including the Schedules, Exhibits,
Buyer Ancillary Agreements when executed and delivered, Seller Ancillary
Agreements when executed and delivered, certificates, documents, and instruments
referred to herein) constitutes the entire agreement and understanding of the
Parties hereto in respect of the transactions contemplated by this Agreement.
There are no restrictions, promises, representations, warranties, covenants, or

therein. This Agreement supersedes all prior or contemporaneous agreements and
understandings between the Parties, whether written or oral, to the extent they
relate in any way to the transactions contemplated by this Agreement.
