Item 2.           Acquisition or Disposition of Assets

         Pursuant to an Asset Purchase Agreement, dated as of May 21, 1996, by
and among Mississippi Chemical Corporation, a Mississippi corporation ("MCC"),
Mississippi Acquisition I, Inc., a Mississippi corporation which is an indirect
wholly-owned subsidiary of MCC ("MI"), Mississippi Acquisition II, Inc., a
Mississippi corporation which is an indirect wholly-owned subsidiary of MCC
("MII"; MI and MII being collectively called the "Designated Buyers"), New
Mexico Potash Corporation, a New Mexico corporation which is an indirect
wholly-owned subsidiary of the Registrant ("NMPC"), and Eddy Potash, Inc., a
Delaware corporation which is a direct wholly-owned subsidiary of the Registrant
("Eddy"; NMPC and Eddy being collectively called the "Sellers"), on August 16,
1996 (the "Closing Date") NMPC and Eddy completed the sale of substantially all
of their assets to MI and MII, respectively, for $45,000,000 plus a working
capital adjustment (described below) and the assumption of specified liabilities
(but excluding, among other things, liabilities, if any, which may arise in
connection with the antitrust litigations in which Sellers are defendants).

         NMPC and Eddy had conducted Registrant's potash mining and production
operations. During the year ended December 31, 1995 and the six month periods
ended June 30, 1995 and June 30, 1996, the potash operations contributed
approximately $54,000,000 (14%), $29,000,000 (15%) and $29,000,000 (12%),
respectively, to the Registrant's revenues, excluding intercompany sales.

         On the Closing Date, the Designated Buyers paid $10,638,000 pursuant to
the above-mentioned working capital adjustment. The final amount of the
adjustment will be determined after completion (within 75 days after the Closing
Date) of a combined Closing

                                        2

Date balance sheet for Sellers, with the amount of any working capital in excess
of $10,638,000 being payable by Designated Buyers and any shortfall from
$10,638,000 being payable by Sellers.

         Approximately 50% of the aggregate proceeds received on the Closing
Date were applied to prepay debt secured by the assets of NMPC or Eddy. In
connection with the sale, Registrant's indirect wholly-owned subsidiary,
Vicksburg Chemical Company, entered into a five year potash supply agreement, at
prevailing market rates during the period (subject to certain adjustments), with
MI.

Item 7. Financial Statements, Pro Forma Financial Information and Exhibits.

(a) Financial Statements of Business Acquired.

         Not Applicable

(b)      Pro Forma Financial Information.

                  The following unaudited Pro Forma Condensed Consolidated
         Financial Statements give effect to the sale of substantially all of
         the assets of NMPC and Eddy as described in Item 2 herein, as if such
         transactions had occurred at (i) the beginning of each period presented
         for the Pro Forma Condensed Consolidated Statements of Operations and
         (ii) June 30, 1996 for the Pro Forma Condensed Consolidated Balance
         Sheet. The Pro Forma Condensed Consolidated Statements of Operations do
         not reflect a net gain of approximately $24.4 million on the sale of
         NMPC's and Eddy's assets. In addition, the Pro Forma Condensed
         Consolidated Statements of Operations reflect no interest earned on the
         sale proceeds.

                  The unaudited Pro Forma Condensed Consolidated Financial
         Statements are based on historical financial information of Registrant
         for the periods referred to above. Pro Forma adjustments are described
         in the accompanying notes. The unaudited Pro Forma Condensed
         Consolidated Financial Statements should be read in conjunction with
         the historical financial statements and the notes thereto included in
         the Registrant's Annual Report on Form 10-K for the year ended December
         31, 1995 and the Registrant's Quarterly Report on Form 10-Q for the six
         month period ended June 30, 1996, previously filed with the Securities
         and Exchange Commission.

                  The unaudited Pro Forma Condensed Consolidated Financial
         Statements are presented for informational purposes only and are not
         necessarily indicative of what the actual financial position or results
         of operations would have been had the transaction occurred on the dates
         indicated, nor do they purport to indicate the future financial
         position or results of future operations of Registrant. In the opinion
         of management, all adjustments necessary to present fairly such
         unaudited Pro Forma Condensed Consolidated Financial Statements have
         been made.

The Pro Forma adjustments reflect the sales of substantially all of the assets
used in the operations of NMPC and Eddy as described in Item 2 herein. The

beginning of each period presented for the Pro Forma Condensed Consolidated
Statements of Operations.

The Pro Forma adjustments for the above transactions are codified as indicated
and are as follows:

    (a)       To reflect the proceeds of approximately $55.6 million from the
              sales and the reduction of the applicable assets and liabilities
              and the estimated net gain relating thereto, after giving effect
              to estimated transaction fees and other costs.

    (b)       To reflect the prepayment of approximately $26.3 million of
              indebtedness secured by the assets of NMPC or Eddy.

    (c)       To reflect the elimination of NMPC's and Eddy's operations.

(the "Closing") shall take place concurrently at the offices of Rubin Baum Levin
Constant & Friedman, 30 Rockefeller Plaza, 29th Floor, New York, New York 10112,
at 10:00 A.M. on the third Business Day following the satisfaction or waiver of
all conditions to the obligations of the Designated Buyers and Sellers to
consummate the transactions contemplated hereby (other than conditions with
respect to actions the respective party will take at the Closing itself) or at
such other place and/or other date as the parties may mutually agree (the
"Closing Date"). In no event shall the Closing Date be later than September 1,
1996. The parties hereto agree that the purchase of the Business Assets of one
Seller cannot be consummated unless the purchase of the Business Assets of the
other Seller is concurrently consummated hereunder.

         3.2      Purchase Price.


                                      -16-
<PAGE>   21
         (a) Subject to any adjustment pursuant to Section 3.2(b) hereof, the
purchase price for the sale of NMPC's Business Assets (the "NMPC Purchase
Price") and the purchase price for the sale of EDDY'S Business Assets (the "EDDY
Purchase Price;" and collectively with the NMPC Purchase Price, the "Purchase
Price") shall be an aggregate of $55,638,000, to be allocated by the parties
hereto between the NMPC Purchase Price and the EDDY Purchase Price (the
"Allocated Purchase Prices") within twenty days after the date hereof (the
"Deadline"), plus in each case the assumption of liabilities provided for in
Section 3.3 hereof, payable at the Closing by the Applicable Designated Buyer by
wire transfer of immediately available funds in the amounts and to the
respective accounts of the Sellers to be furnished by the respective Sellers to
the Applicable Designated Buyer prior to the Closing Date.

                  If the parties fail to agree on the Allocated Purchase Prices
by the Deadline, on the first Business Day thereafter Sellers and Designated
Buyers shall either agree upon a firm of certified public accountants to
determine the Allocated Purchase Prices or shall each select a firm of certified
public accountants of nationally recognized standing in order for such two firms
to select on the second Business Day after the Deadline a third firm of
certified public accountants to determine the Allocated Purchase Prices. If by
the end of the fifth Business Day after the Deadline, a firm has not yet been
selected pursuant to the foregoing procedures to determine the Allocated
Purchase


                                      -17-

Prices, then the firm shall be a firm of certified public accountants designated
by the American Arbitration Association at the request of any party. The firm
engaged shall be requested to determine the Allocated Purchase Prices no later
than the fifteenth Business Day after the Deadline, and its decision shall be
final and binding upon the parties. The parties shall be responsible for their
respective expenses in connection with this determination, except that the fees
of the firm agreed upon by the parties (or otherwise designated to determine the
Allocated Purchase Prices in accordance herewith) shall be divided equally
between Designated Buyers, on the one hand, and Sellers, on the other.

         (b) Promptly following the Closing Date (but in any event no later than
seventy five days after the Closing Date) Sellers shall, at the expense of
Designated Buyers and Sellers to be shared equally, prepare a combined balance
sheet for Sellers' Businesses (after eliminating the Excluded Assets and the
Excluded Liabilities), as at the Closing Date (the "Closing Balance Sheet") in a
manner consistent with the preparation of the Pro Forma Financial Statements
which shall be reported on without qualification by the independent auditing
firm of one of the Sellers. If Designated Buyers do not give written notice to
Sellers setting forth detailed objections to the Closing Balance Sheet (the
"Objection Notice") within 20 days of said delivery, it shall be final and
binding on the parties. If there is a dispute between Sellers and Designated
Buyers with respect to the


                                      -18-
<PAGE>   23
Closing Balance Sheet and Sellers and Designated Buyers are unable to resolve
such dispute within 15 days of receipt of the Objection Notice, such dispute
shall be resolved as expeditiously as possible by a firm of certified public
accountants mutually acceptable to the parties. If the parties are unable to
agree upon a firm of certified public accountants within 5 days, then Sellers
and Designated Buyers shall within 5 days thereafter, by notice to the other,
set forth the name of a firm of certified public accountants. The two firms
designated by the parties shall as promptly as possible select a third firm of
certified public accountants to resolve the dispute; provided, however, that if
the firms are unable to agree upon a third firm within seven Business Days after
the second of such firms is selected or if Sellers or Designated Buyers fail to
select a firm, then the third firm of certified public accountants shall be a
firm of certified public accountants designated by the American Arbitration
Association at the request of any party. The decision of the firm of certified
public accountants mutually acceptable to the parties (or such other firm of
certified public accountants designated in accordance herewith to resolve the
dispute) shall be final and binding upon Sellers and Designated Buyers and the
Closing Balance Sheet as approved by such firm of certified public accountants
shall be the Closing Balance Sheet hereunder. The parties shall be responsible
for their respective expenses in connection with such resolution, except for the
fees of the firm of certified public accountants mutually acceptable to the par-


                                      -19-

shall be divided equally between Designated Buyers, on the one hand, and
Sellers, on the other. In the event that the combined working capital of
Sellers' Businesses (computed by subtracting the current liabilities from the
current assets (excluding deferred taxes and eliminating Excluded Assets,
including, without limitation, prepaid insurance, and Excluded Liabilities), all
as set forth in the Closing Balance Sheet)), is greater or less than
$10,638,000, Designated Buyers shall pay to Sellers, in the aggregate, the
amount of such excess, allocated as specified by Sellers, or Sellers shall pay
to Designated Buyers, in the aggregate, the amount of such shortfall, allocated
as specified by Designated Buyers, in cash within five days after the delivery
of the Closing Balance Sheet.

                                         (v) Notwithstanding the foregoing, each
party hereto agrees and acknowledges that no party hereto shall be required to
divest or hold separate or otherwise take or commit to take any material action
that, prior to the Closing, materially limits its freedom of action with respect
to, or its ability to retain, the business of such party.
    
                   (c) Full Access. Each Seller will permit representatives of
Parent and Applicable Designated Buyer to have full access at all reasonable
times, and in a manner so as not to unreasonably interfere with its normal
business operations, to all of its premises, properties, personnel, books,
records (including tax records), contracts, and documents. Parent and Designated
Buyers will, and will cause their representatives to, treat and hold as such any
Confidential Information they receive from a Seller in the course of the reviews
contemplated by this Section 5.1(c), will, and will cause their representatives
to, not use any of the Confidential Information except in connection with this
Agreement, and, if this Agreement is terminated for any reason whatsoever, will,
and will cause their representatives to, return to the respective Seller all
tangible embodiments (and all copies) of the Confidential Information which are
in their possession and will not take business advantage of any such
information.

                   (d) Operation of Business. Prior to the Closing Date, each

                                      -48-

efforts to (i) preserve its present business organization, (ii) keep available
the services of substantially all of its present officers and employees, (iii)
preserve present material business relationships, (iv) maintain and keep the
Business Assets, (v) not purchase, sell, lease, encumber or otherwise dispose of

practice, (vi) maintain in full force and effect insurance comparable in amount
and in scope of coverage to that now maintained, (vii) pay and perform, when
due, all material obligations under contracts, leases and documents relating to
or affecting the Business Assets and the Business of such Seller, except where
such Seller is disputing the foregoing in good faith, and (viii) comply with and
perform all material obligations and duties imposed by federal, state and local
laws, and all rules, regulations and orders imposed by federal, state or local
governmental authorities, except in the case of clauses (vii) or (viii) as set
forth on Schedule 5.1(d) or where the failure to so pay, perform or comply would
not have a Material Adverse Effect. In addition, prior to the Closing Date, a
Seller shall not, without the prior written consent of Applicable Designated
Buyer, borrow or agree to borrow any funds or guarantee or agree to guarantee
the obligations of others, except pursuant to the $3,000,000 Credit Agreement,
dated as of October 13, 1995, between EDDY and General Electric Capital

between NMPC's parent corporation, Cedar Chemical Corporation ("Cedar"), The
Chase Manhattan Bank, N.A., as Administrative Agent and the other parties
thereto, or except where any such borrowing or guarantee will not result in any
liability or obligation to be assumed by Designated Buyer. Each Seller shall
notify Applicable Designated Buyer of any unexpected emergency or other change
in the normal course of Seller's Business or in the operation of Seller's
properties and of any governmental complaints, investigations, or hearings (or
communications indicating that the same may be contemplated), adjudicatory
proceedings, and keep Applicable Designated Buyer informed of such events.

                  (e) Exclusivity. Sellers shall negotiate exclusively with
Parent and Designated Buyers with respect to the acquisition of the Business
Assets and shall not directly or indirectly: (i) solicit any other buyers for
all or any part of the capital stock or assets of Sellers; (ii) encourage any
third parties to bid for any of the assets of Sellers or to purchase shares of
the capital stock of Sellers or participate in any negotiations or discussions
with any such third parties with respect thereto; (iii) provide business or
financial information (not otherwise publicly available) concerning Sellers to
any third parties except in the ordinary course of business; or (iv) assist or
cooperate with any third party to make any proposal to purchase all or any part
of the capital stock or assets of Sellers. In addition, Sellers shall direct

                  (f) Letters of Credit; Security Deposits, Surety Bonds. On or

best efforts to cooperate with Seller to secure releases from all such Seller's
obligations under all letters of credit, security deposits, surety and

are set forth on Schedule 5.1(f) and will furnish all instruments to the
reasonable satisfaction of the party secured thereby.

                  (g) Confidentiality Agreements. During the period from the
date of this Agreement through the Closing Date, each Seller shall not
terminate, amend, modify or waive any provision of any confidentiality agreement
to which it is a party. During such period, each Seller shall enforce, to the
fullest extent permitted under applicable law, the provisions of any such
agreement, including, but not limited to, by obtaining injunctions to prevent
any breaches of such agreements and to enforce specifically the terms and
provisions thereof in any court of the United States of America or of any state

         Article 6  Post-Closing Covenants.

         6.1      Certain Employee Matters.

                  (a) Current Employees. (1) The Applicable Designated Buyer
agrees to offer employment, as of the Closing Date, to substantially all
individuals then currently employed by the


                                      -51-
<PAGE>   56
respective Seller or any Affiliate thereof, who are then currently engaged in
the Business and are listed on Schedule 6.1(a) ("Business Employees"). On or
before the Closing Date, each Applicable Designated Buyer shall deliver to
Seller a list of Business Employees of such Seller to whom it will not be
offering employment as of the Closing Date. Sellers make no representations or
warranties regarding which, if any, Business Employees will accept Designated
Buyers' offers of employment.

                           (2)      Applicable Designated Buyer shall continue
the terms of employment of any Business Employee who accepts employment with
such Designated Buyer ("Continued Employee") with respect to current rates of
compensation, levels of job seniority and benefits that are, in the aggregate,
substantially equivalent, until at least 90 days after the Closing Date.
Thereafter, except as expressly provided elsewhere in this Agreement, including
this Section 6.1, Applicable Designated Buyer, in its sole discretion, may
modify the terms and conditions of employment of any Continued Employee. Nothing
herein shall prevent Applicable Designated Buyer from disciplining any employee,
or terminating any employee for cause, or, except as expressly provided in this
Agreement, including this Section 6.1, from amending or terminating any Employee
Benefit Plan, regardless of whether such action occurs within 90 days after the
Closing Date.


                                      -52-
<PAGE>   57
                           (3)      Nothing expressed or implied in this Agree-
ment, including this Section 6.1, is intended to confer upon any Employee or his
legal representatives any rights or remedies, including, without limitation, any
rights of employment for any specified period, of any nature or kind whatsoever
under or by reason of this Agreement.

                  (b) Medical, Insurance and Other Benefits. (1) (A) All
expenses or claims covered under medical, travel accident, accidental death and
dismemberment and life insurance plans (if any) of a Seller and which have been
incurred by Employees and their dependents before the Closing Date, irrespective
of the time at which claims are presented, are the responsibility of such Seller
and shall be paid directly by such Seller or its insurance carrier to such
Employees and their dependents. No amount for the above-mentioned expenses or
claims shall be included as current liabilities on the Closing Balance Sheet.
All expenses or claims covered under medical, travel accident, accidental death
and dismemberment and life insurance plans (if any) of a Designated Buyer and
which are incurred by Continued Employees and their dependents on or after the
Closing Date, including any expenses attributable to facts or conditions exist-
ing on or before the Closing Date, are the responsibility of such Designated
Buyer and shall be paid directly by such Designated Buyer or its insurance
carrier to such Continued Employees and dependents. To the extent permitted by
law, each Designated Buyer agrees to provide credit toward the payment of any


                                      -53-
<PAGE>   58
deductible and to recognize past service of Continued Employees with a Seller or
any Affiliate thereof for the purpose of any such plans it adopts for the
benefit of Continued Employees. Except as expressly provided elsewhere in this
Agreement, including this Section 6.1, nothing in this subsection (b)(1)(A)
shall require a Designated Buyer to provide any such plans or benefits to any
employee.

                                    (B) Except as expressly provided elsewhere
in this Agreement, including this Section 6.1, each Designated Buyer in its sole
discretion may determine the terms of any group health insurance plan that it
may elect to provide Continued Employees and their dependents and may modify or
terminate such plan at any time; provided, however, that effective as of the
Closing Date, each Designated Buyer agrees to provide to Continued Employees and
their dependents a group health plan without any exclusion for pre-existing
conditions. As soon as practicable, each Applicable Designated Buyer agrees to
furnish the respective Seller with information as to which Continued Employees
have enrolled in such plan.

                                    (C) Notwithstanding anything in subsection
(b)(1)(B) to the contrary, a Designated Buyer shall not be required to provide
coverage for pre-existing conditions, or for persons who are not actively at
work or who are confined in a hospital, other institution or at home under a
physician's care as of the Closing Date, in a group health plan with respect to


                                      -54-
<PAGE>   59
Continued Employees if such Designated Buyer uses its best efforts to obtain
coverage for pre-existing conditions and such persons either (i) from its
stop-loss carrier on reasonable terms or (ii) by assuming or continuing Seller's
existing stop-loss insurance coverage on reasonable terms and is unable to
obtain such coverage from either such insurance carrier or to assume or continue
such coverage on reasonable terms. Each respective Seller agrees to provide
Applicable Designated Buyer such information as it may request for purposes of
seeking such coverage. Prior to the Closing Date, each Designated Buyer agrees
to furnish the respective Seller with information as to whether an exclusion for
pre-existing conditions or for persons specified in this subsection (b)(1)(C)
applies to Continued Employees.

                           (2)      All short-term, long-term and extended dis-
ability benefits under the terms of a Seller's plans (if any) payable to a
Seller's Employees and their dependents who became disabled before the Closing
Date are the responsibility of such Seller and shall be paid directly by such
Seller or its insurance carrier to such Employees and their dependents. No
amount for the above-mentioned benefits shall be included in current liabilities
on the Closing Balance Sheet. All short-term, long-term and extended disability
benefits under the terms of a Designated Buyer's plans (if any) payable to
Continued Employees and their dependents who become disabled on or after the
Closing Date shall be the responsibility of such Designated Buyer and


                                      -55-
<PAGE>   60
shall be paid directly by such Designated Buyer or its insurance carrier to such
Continued Employees and their dependents. Except as expressly provided elsewhere
in this Agreement, including this Section 6.1, nothing in this subsection (b)(2)
shall require a Designated Buyer to provide any such plans or benefits to any
Continued Employee.

                           (3) Each Seller agrees to fulfill its obligations
under continuation coverage rules of COBRA with respect to a "qualifying event,"
within the meaning of Section 4980B(f) of the Code or Section 603 of ERISA,
occurring on or before the Closing Date with respect to any Employees and their
dependents. Each Designated Buyer shall fulfill all such obligations with
respect to any "qualifying event" that occurs after the Closing Date with
respect to any Continued Employees and their dependents.

                           (4) If any Employees are terminated from employ- ment
by a Seller as a result of the transactions contemplated by this Agreement or
otherwise, any obligations arising out of such termination of employment,
including but not limited to severance (including any severance payments due
under the terms of the Eddy Potash, Inc. Severance Pay Benefit Plan, an Employee
Welfare Benefit Plan and Trust), accrued vacation pay, COBRA obligations,
notices or compensation required under the Worker Adjustment and Retraining
Notification ("WARN") Act, employment discrimination complaints, unfair labor
practice charges, grievance under any collective bargaining agreement, breach of
contract claims, and


                                      -56-
<PAGE>   61
wrongful termination and related tort claims shall be the sole responsibility of
such Seller. If any Continued Employees are terminated by Applicable Designated
Buyer, any obligations arising out of such termination of employment, including
but not limited to severance, accrued vacation pay, COBRA obligations, notices
or compensation required under the Worker Adjustment and Retraining Notification
("WARN") Act, employment discrimination complaints, unfair labor practice
charges, grievance under any collective bargaining agreement, breach of contract
claims, and wrongful termination and related tort claims, shall be the sole
responsibility of Applicable Designated Buyer. Nothing in this subsection (b)(4)
shall require Applicable Designated Buyer to provide any severance pay benefits,
medical coverage, vacation, or other benefits to any employee or former employee
except as expressly provided elsewhere in this Agreement, including this
Section 6.1. Except as expressly provided elsewhere in this Agreement,
including this Section 6.1, each Applicable Designated Buyer reserves the sole
right to design, structure, amend or terminate any severance plan, medical
plan, vacation policy, or other plan or policy as it sees fit.

                           (5) With respect to Continued Employees, Applicable
Designated Buyer shall continue to apply the vacation policy of the respective
Seller or any Affiliate thereof that is currently in effect (the "Seller's
Vacation Policy") at least until December 31, 1996 so that each Continued
Employee shall be entitled to use any vacation time and receive any vacation pay
to


                                      -57-
<PAGE>   62
which he or she would otherwise be entitled until at least December 31, 1996
under such Seller's Vacation Policy. Thereafter, Applicable Designated Buyer may
in its sole discretion amend, modify, or terminate such Seller's Vacation
Policy. From and after the Closing Date, Applicable Designated Buyer will
recognize past service of Continued Employees with the respective Seller or any
Affiliate thereof for purposes of all vacation policies of Applicable Buyer
applicable to Continued Employees.

                           (6) After the Closing Date, each Designated Buyer and
each Seller shall each provide the other on a continuing basis at no cost to the
other such information regarding Continued Employees as the other shall
reasonably request.

                           (7) NMPC agrees that as of the Closing Date it shall
terminate its severance policy for the benefit of its Employees.

                  (c) Designated Buyers' Plans. Each Designated Buyer shall
cause each Continued Employee to be eligible to participate in a defined
contribution plan qualified under Code Section 401(a) and 401(k) ("Buyer Plan").
To the extent permitted by law, the Applicable Designated Buyer shall cause each
Continued Employee to be granted credit for service with Seller or any affiliate
thereof for purposes of eligibility and vesting in such Designated Buyer's Plan.


                                      -58-
<PAGE>   63
                  (d) Supersession. This Section 6.1 shall govern employee
benefits and labor and employment matters and shall supersede any provision in
this Agreement to the contrary.

         6.2 Record Retention and Winding Up. All of a Seller's files of
correspondence, lists, records (in whatever medium the records are stored),
manuals and books of account concerning past, present and prospective customers
and compliance with the rules and regulations of all federal, state or local
regulatory agencies including, without limitation, with respect to matters
relating to the litigations which are set forth on Schedule 4.1(c)
("Litigations"), required by such Seller, including, without limitation, for use
in connection with the Litigations or for the preparation of tax returns and the
like (collectively, "Filings"), shall be made available to such Seller and its
Affiliates, during normal business hours and without unreasonable interference
with the business operations of the Applicable Designated Buyer or Parent, for
examination and duplication (at such Seller's expense) after the Closing Date
for a period of five years. Thereafter, at least 60 days prior to destroying any
of said files, lists, records, manuals and books of account, the Applicable
Designated Buyer shall give notice of its intention to do so to the respective
Seller. If such Seller shall notify the Applicable Designated Buyer that it
wishes to retain any of such files, lists, records, manuals or books of account
which such Designated Buyer intends to destroy, the Applicable Designated Buyer
shall (at such Seller's expense) deliver such files, lists,


                                      -59-
<PAGE>   64
records, manuals or books of account to a location designated by such Seller in
said notification.

         6.3 Cooperation. Each Designated Buyer agrees that it shall cooperate
with each Seller in connection with the Litigations by providing upon reasonable
notice the services of employees of such Designated Buyer having knowledge of
facts in connection therewith in order to assist such Seller in the preparation
of such Seller's defenses and to testify at depositions or trials thereof. Each
Designated Buyer also agrees that it shall cooperate with Sellers in connection
with any Filings by providing upon reasonable notice the services of Employees
of such Designated Buyer having knowledge of facts in connection therewith in
order to assist each Seller in connection therewith. In consideration of the
foregoing, each Seller agrees that it shall pay to Designated Buyer the
reasonable cost of the time expended by such Designated Buyer's personnel and
shall reimburse the reasonable out-of-pocket costs incurred by such employees in
providing such testimony or assistance and the costs of all photocopying and
delivery of any documents provided to a Seller by such Designated Buyer.

         6.4 Name Change. Within 30 days after the Closing, each Seller agrees
to amend its charter documents to change its corporate name to a name bearing no
resemblance to its current name so as to make each Seller's corporate name
available to the Applicable Designated Buyer.

below shall survive termination, and (ii) if such termination shall result from
the willful failure of any party to fulfill a condition to the performance of
the obligations of another party or to perform a covenant of this Agreement or
from a willful breach of any party to this Agreement, such party shall be fully
liable for any and all losses and damages incurred or suffered by the other

                  (a) The representations and warranties made in this Agreement,

                           (1)      Except for the representation and set forth

warranties in this Agreement shall expire and be of no further force and effect

                           (2)      The representations and warranties made by

<PAGE>   72
                           (3)      The representations and warranties made by
Sellers in Sections 4.1(e) and 4.1(g) shall survive and remain in full force and
effect until the expiration of the applicable statutes of limitation by which
any governmental authority, or party, as the case may be, may assert a claim
with respect to the subject matter of such Section.

                  (b) Each of the parties acknowledges that there are no
representations or warranties by or on behalf of any party hereto or any of its
respective Affiliates or representatives other than those expressly set forth in
this Agreement or on a Schedule hereto.

                  (c) All references in this Article 9 to "losses," "damages" or
any "deficiency" suffered or incurred by a party or its Affiliates shall be: (i)
deemed to include all reasonable costs and expenses (including reasonable
attorneys' fees, amounts paid as judgments or settlements and costs of
investigation) incurred by the Person entitled to indemnification in connection
with any action, suit, proceeding, demand, assessment or judgment incident to
any of the matters for which such person is indemnified against under this
Agreement; and (ii) reduced by the amount of proceeds recovered from any
indemnification, contribution or right over, or from and against, any Person who
is not an Affiliate of such party. Parent, each Designated Buyer and each
Seller, as the case may be, shall each take all reasonable steps to recover
under any applicable right of indemnification or


                                      -68-
<PAGE>   73
contribution from Persons other than a party hereto, but its failure to make any
such recovery shall not serve to limit or impair its rights under this Article
9.

         9.2 Seller's Indemnification. Subject to the limitations and
restrictions contained elsewhere in this Article 9, each Seller hereby agrees
(severally and not jointly) to indemnify, defend and hold the Applicable
Designated Buyer and Parent, their Affiliates, successors and assigns and their
respective representatives (collectively, "Buyer's Indemnitees") harmless from
and against any and all losses that such Buyer's Indemnitees may at any time
suffer or incur, or become subject to, as a result of or in connection with (i)
any breach or inaccuracy of any of the representations and warranties made by
such Seller in or pursuant to this Agreement if asserted by Buyer's Indemnitees
during the period that such representations and warranties survive; (ii) any
failure by such Seller to carry out perform, satisfy and discharge any of its
covenants, agreements, undertakings, liabilities or obligations under this
Agreement or under any of the documents and instruments delivered by such Seller
pursuant to this Agreement; (iii) claims by third parties against the Applicable
Designated Buyer relating to the operation and ownership by such Seller of the
Business Assets, the performance by such Seller under the Assumed Liabilities,
the conduct of the business of such Seller prior to the Closing Date and the
performance by Seller under the Excluded Liabilities and (iv) indebtedness, if
any, of the Sellers which Applicable Designated


                                      -69-
<PAGE>   74
Buyer pays to BLM pursuant to the letter from Designated Buyers to BLM attached
hereto as Schedule 9.2. Notwithstanding the foregoing, Sellers shall not be
required to indemnify Buyer's Indemnitees under this Section 9.2 (other than
under clause (iv) above) unless and until the aggregate amount of such losses
shall exceed $250,000 at which time Sellers will be obligated to indemnify
Buyer's Indemnitees for all additional losses in excess of $250,000; provided,
however, in no event shall Sellers be liable to Buyer's Indemnitees hereunder
(including pursuant to (iv) above) for an amount in excess of $5,000,000 (in the
aggregate for both Sellers and for Buyer's Indemnitees of both Designated
Buyers).

         9.3 Designated Buyer's Indemnification. The Designated Buyers hereby
jointly and severally agree to indemnify, defend and hold each Seller, its
Affiliates, successors and assigns and their respective representatives
(collectively, "Seller's Indemnitees") harmless from and against any and all
losses that Seller's Indemnitees may at any time suffer or incur, or become
subject to, as a result of or in connection with (i) any breach or inaccuracy of
any of the representations and warranties made by Parent or a Designated Buyer
in or pursuant to this Agreement; (ii) any failure of a Designated Buyer to
carry out, perform, satisfy and discharge any of its covenants, agreements,
undertakings, liabilities or obligations under this Agreement or under any of
the documents and instruments delivered by a Designated Buyer pursuant to this
Agreement; and (iii) claims by third par-


                                      -70-
<PAGE>   75
ties against a Seller or its Affiliates relating to the operation and ownership
by a Designated Buyer of the Business Assets, the performance by a Designated
Buyer under the Assumed Liabilities and the conduct of the business of a
Designated Buyer (so long as such claims or losses arise from events that
occurred after the Closing Date).

         9.4 Defense of Claims. A Seller and a Designated Buyer shall each give
prompt notice to the other of any claim against the party giving notice which
might give rise to a claim based upon any indemnity contained herein. The notice
shall set forth in reasonable detail the nature and basis of the claim and the
actual or estimated amount thereof. The failure to provide such notice promptly
will not relieve the indemnifying party of its obligations under Article 9
unless and only to the extent that the failure to give such notice promptly
materially prejudiced the ability of the indemnifying party to defend against
such claim. In the event any action, suit or proceeding is brought against a
party with respect to which the other party hereto may have liability under any
indemnity contained herein, the indemnifying party shall have the right, at its
sole cost and expense, to defend such action in the name and on behalf of the
indemnified party with counsel reasonably satisfactory to the indemnified party.
The parties hereto agree to render to each other such assistance as may
reasonably be required in order to ensure the proper and adequate defense of any
such action, suit or proceeding. The indemnified party shall have the right to
partici-


                                      -71-
<PAGE>   76
pate, at its own expense and with counsel of its choosing, in the defense of any
claim against which it is indemnified hereunder and it shall be kept fully
informed with respect thereto. The party seeking indemnification hereunder shall
not make any settlement of any claim which might give rise to liability of
another party under any indemnity contained herein without the prior written
consent of such other party, which consent shall not be unreasonably withheld.

         9.5 Guarantee. NMPC covenants that on or prior to Closing, it will
deliver to MI a guarantee of Cedar, in a form reasonably satisfactory to MI, of
NMPC's obligations under Section 9.2. EDDY covenants that on or prior to
Closing, it will deliver to MII a guarantee of Trans-Resources, Inc. ("TRI"), in
a form reasonably satisfactory to MII, of EDDY's obligations under Section 9.2.

         Article 10 Miscellaneous.

         10.1 Press Releases and Public Announcements. No party hereto or
Affiliate thereof shall issue any press release or make any public announcement
relating to the subject matter of this Agreement without the prior written
approval of Parent and TRI; provided, however, that any party hereto or
Affiliate thereof may make any public disclosure it believes in good faith is
required by applicable law or any listing or trading agreement concerning its
publicly-traded securities (in which case the disclosing


                                      -72-

entity will use its reasonable best efforts to advise the other (unaffiliated)

benefit of the parties hereto and their respective successors and permitted

warranties, undertakings, covenants and agreements between the parties. This
Agreement may not be changed, modified, altered or terminated except by an
agreement in writing executed by the parties hereto. Any waiver by any party of

herein expressed or implied is intended or shall be construed to confer upon or
give to any person or entity other than the parties hereto and their successors

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 of
the provisions of this Agreement. Any reference to any federal, state, local, or

                                      -74-
<PAGE>   79
the context requires otherwise.  The word "including" shall mean including
without limitation.

of reference only and shall not control or affect the meaning or construction
of any provisions of this Agreement.

         10.9  Counterparts. This Agreement may be executed in any number of
counterpart copies and by telecopier, each of which shall be deemed an original,
but which together shall constitute a single instrument.

responsibility for any of Designated Buyers' duties or obligations under this
Agreement.

         Re:      Amendment to Asset Purchase Agreement, dated as of May 21,
                  1996 (the "Purchase Agreement"), among Mississippi Chemical
                  Corporation, Mississippi Acquisition I, Inc., Mississippi
                  Acquisition II, Inc., Eddy Potash, Inc. and New Mexico Potash
                  Corporation

Gentlemen:

         Reference is made to Sections 4.1(f) and 7.1(g) of the Purchase
Agreement. Terms defined in the Purchase Agreement are used herein as defined
therein.

         By signing below, please confirm our agreement as follows:

         1. With respect to consents and/or approvals of the New Mexico State
Land Office, Sections 4.1(f) and 7.1(g) will be deemed satisfied by the letter,
dated August 15, 1996, from the New Mexico State Land Office attached hereto as
Exhibit A.

         2. Notwithstanding that the items listed on Exhibit B hereto (the
"Existing Arrangements") were identified on Schedule 4.1(f) to the Purchase
Agreement as "Required Consents," such consents are not necessary and obtaining
these consents will not be a condition to Closing because the Designated Buyers
are entering into newly negotiated alternate arrangements with the third parties
to the Existing Arrangements (the "Alternate Arrangements"). Your signature
below will also confirm that (i) Designated Buyers' entry into these Alternate
Arrangements will not create any liabilities to Sellers as a result of the
concomitant termination of the Existing Arrangements, and (ii) that no
liabilities will accrue to Sellers under the Existing Arrangements for periods
after the Closing Date.

         3. If the Closing occurs on August 16, 1996, it will be deemed to have
occurred as of 7:00 A.M. Carlsbad, New Mexico time on that date.

         4. Effective as of the date hereof, Section 9.2 of the Purchase
Agreement is hereby
<PAGE>   2
amended to read in its entirety as follows:

         "9.2 Seller's Indemnification. Subject to the limitations and
restrictions contained elsewhere in this Article 9, each Seller hereby agrees
(severally and not jointly) to indemnify, defend and hold the Applicable
Designated Buyer and Parent, their Affiliates, successors and assigns and their
respective representatives (collectively, "Buyer's Indemnitees") harmless from
and against any and all losses that such Buyer's Indemnitees may at any time
suffer or incur, or become subject to, as a result of or in connection with (i)
any breach or inaccuracy of any of the representations and warranties made by
such Seller in or pursuant to this Agreement if asserted by Buyer's Indemnitees
during the period that such representations and warranties survive; (ii) any
failure by such Seller to carry out perform, satisfy and discharge any of its
covenants, agreements, undertakings, liabilities or obligations under this
Agreement or under any of the documents and instruments delivered by such Seller
pursuant to this Agreement; (iii) claims by third parties against the Applicable
Designated Buyer relating to the operation and ownership by such Seller of the
Business Assets, the performance by such Seller under the Assumed Liabilities,
or the conduct of the business of such Seller, in each case prior to the Closing
Date, and the performance by Seller under the Excluded Liabilities and (iv)
indebtedness, if any, of the Sellers which Applicable Designated Buyer pays to
BLM pursuant to the letter from Designated Buyers to BLM attached hereto as
Schedule 9.2, and (v) indebtedness, if any, of the Sellers which Applicable
Designated Buyer pays to the New Mexico State Land Office (the "State Land
Office") for the royalties, if any, owed to the State Land Office on or prior to
the Closing Date in connection with the Leases between a Seller and the State
Land Office listed on Schedule 2.1(5) hereto. Notwithstanding the foregoing,
Sellers shall not be required to indemnify Buyer's Indemnitees under this
Section 9.2 (other than under clauses (iv) and (v) above) unless and until the
aggregate amount of such losses shall exceed $250,000 at which time Sellers will
be obligated to indemnify Buyer's Indemnitees for all additional losses in
excess of $250,000; provided, however, in no event shall Sellers be liable to
Buyer's Indemnitees hereunder (including pursuant to (iv) above, but other than
under clause (v) above) for an amount in excess of $5,000,000 (in the aggregate
for both Sellers and for Buyer's Indemnitees of both Designated Buyers)."

         This Amendment may be signed in counterparts and by telecopied
signature.
