                AGREEMENT AND PLAN OF MERGER AND REORGANIZATION
 
  AGREEMENT AND PLAN OF MERGER AND REORGANIZATION, dated as of August 27,
1996, by and among Mississippi Chemical Corporation, a Mississippi corporation
("Parent"), Miss Sub, Inc., a Mississippi corporation and a wholly owned
subsidiary of Parent ("Sub"), and First Mississippi Corporation, a Mississippi
corporation (the "Company").
 
  WHEREAS, Parent desires to acquire the Company's fertilizer business but
does not wish to acquire the other businesses conducted or to be conducted by
the Company;
 
  WHEREAS, the Board of Directors of the Company has approved a plan of
distribution embodied in the form of a draft agreement attached hereto as
Annex I, as may be amended pursuant to the provisions of Section 6.11 hereof
(the "Distribution Agreement"), which will be entered into prior to the
Effective Time (as defined in Section 1.2) pursuant to which all of the
Company's assets, other than those used primarily in the Retained Business (as
defined in Section 3.7), will be contributed to a wholly owned subsidiary of
the Company ("Newco") (such contributions, together with all mergers, other
intercompany transfers of assets, and other actions described in Article IV of
the Distribution Agreement, the "Transfer") and shares of capital stock of
Newco will be distributed (the "Distribution") on a pro rata basis to the
stockholders of the Company as provided in the Distribution Agreement in order
to divest the Company of the businesses and operations that Parent is
unwilling to acquire;
 
  WHEREAS, the respective Boards of Directors of Parent, Sub and the Company
have determined that, following the Distribution, the merger of Sub with and
into the Company (the "Merger") with the Company surviving as a wholly owned
subsidiary of Parent would be advantageous and beneficial to their respective
corporations and stockholders; and
 
  WHEREAS, for federal income tax purposes, it is intended that (i) the
Distribution shall qualify as a tax-free distribution under Section 355 of the
Internal Revenue Code of 1986, as amended (the "Code"), and (ii) the Merger
shall qualify as a reorganization under Section 368(a) of the Code, and this
Agreement is intended to be and is adopted as a plan of reorganization.
 
  NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, the
parties hereto agree as follows:
 
                                   ARTICLE I
 
                                  The Merger
 
  Section 1.1 The Merger. Upon the terms and subject to the conditions hereof
and the Mississippi Business Corporation Act (the "MBCA"), at the Effective
Time, the Company and Sub shall consummate the Merger pursuant to which (i)
Sub shall be merged with and into the Company, (ii) the separate corporate
existence of Sub shall thereupon cease, (iii) the Company shall be the
surviving corporation in the Merger (the "Surviving Corporation") and shall
continue to be governed by the laws of the State of Mississippi and (iv) the
corporate existence of the Company with its properties, rights, privileges,
powers and franchises shall continue unaffected by the Merger.
 
  Section 1.2 Effective Time of the Merger. Upon the terms and subject to the
conditions hereof, articles of merger (the "Articles of Merger") shall be duly
prepared, executed and acknowledged by the Company and thereafter delivered to
the Secretary of State of the State of Mississippi, for filing, as provided in
the MBCA, as soon as practicable on or after the Closing Date (as defined in
Section 1.3). The Merger shall become effective
 
                                       1

 
immediately following the Distribution, upon the filing of the Articles of
Merger with the Secretary of State of the State of Mississippi or at such time
thereafter as is provided in the Articles of Merger (the "Effective Time").
 
  Section 1.3 Closing. The closing of the Merger (the "Closing") will take
place at 10:00 a.m. on a date to be specified by the parties, which shall be
no later than the second business day after satisfaction or waiver of the
conditions set forth in Article VII hereof, at the offices of the Company, 700
North Street, Jackson, Mississippi 39202-3095, unless another date or place is
agreed to in writing by the parties hereto. The date and time at which the
Closing occurs is referred to herein as the "Closing Date."
 
  Section 1.4 Effects of the Merger. The Merger shall have the effects set
forth in the MBCA. Without limiting the generality of the foregoing, and
subject thereto, at the Effective Time, all the properties, rights,
privileges, powers and franchises of Sub shall vest in the Surviving
Corporation, and all debts, liabilities and duties of Sub shall become the
debts, liabilities and duties of the Surviving Corporation.
 
  Section 1.5 Articles of Incorporation and Bylaws.
 
    (a) The Articles of Incorporation of Sub in effect at the Effective Time
  shall be the Articles of Incorporation of the Surviving Corporation until
  amended in accordance with the MBCA.
 
    (b) The bylaws of Sub in effect at the Effective Time shall be the bylaws
  of the Surviving Corporation until amended in accordance with the MBCA.
 
  Section 1.6 Directors. The directors of Sub at the Effective Time shall be
the initial directors of the Surviving Corporation, each to hold office from
the Effective Time in accordance with the Articles of Incorporation and bylaws
of the Surviving Corporation and until his or her successor is duly elected
and qualified.
 
  Section 1.7 Officers. The officers of Sub at the Effective Time shall be the
initial officers of the Surviving Corporation, each to hold office from the
Effective Time in accordance with the Articles of Incorporation and bylaws of
the Surviving Corporation and until his or her successor is duly appointed and
qualified.
 
                                  ARTICLE II
 
                           Conversion of Securities
 
  Section 2.1 Conversion of Capital Stock. As of the Effective Time, by virtue
of the Merger and without any action on the part of the holders of any shares
of Common Stock, par value $1.00 per share, of the Company (the "Company
Common Stock") or Parent, as the holder of the capital stock of Sub:
 
    (a) Capital Stock of Sub. Each issued and outstanding share of the
  capital stock of Sub shall be converted into and become one fully paid and
  nonassessable share of Common Stock, par value $1.00 per share, of the
  Surviving Corporation.
 
    (b) Cancellation of Treasury Stock and Parent-Owned Stock. All shares of
  Company Common Stock that are owned by the Company and any shares of
  Company Common Stock owned by Parent, Sub or any other wholly-owned
  Subsidiary (as hereinafter defined) of Parent shall be cancelled and
  retired and shall cease to exist and no stock of Parent or other
  consideration shall be delivered in exchange therefor. As used in this
  Agreement, the word "Subsidiary" means, with respect to any party, any
  corporation or other organization, whether incorporated or unincorporated,
  of which (i) such party or any other Subsidiary of such party is a general
  partner (excluding partnerships the general partnership interests of which
  held by such party and any Subsidiary of such party do not have a majority
  of the voting interest in such partnership) or (ii) securities or other
  interests having by their terms a majority of the outstanding voting power
  with
 
                                       2

 
  respect to such corporation or other organization are directly or
  indirectly owned or controlled by such party or by any one or more of its
  Subsidiaries, or by such party and one or more of its Subsidiaries.
 
    (c) Exchange Ratio for Company Common Stock. Subject to Section 2.2(e),
  each issued and outstanding share of Company Common Stock (other than
  shares to be cancelled in accordance with Section 2.1(b) and Dissenting
  Shares, as defined in Section 2.3) shall be converted into the right to
  receive the Merger Consideration Per Share in fully paid and nonassessable
  shares of Common Stock, par value $0.01 per share, of Parent ("Parent
  Common Stock"). The "Merger Consideration Per Share" shall mean 6,904,762
  shares of Parent Common Stock divided by the number of shares of Company
  Common Stock outstanding at the Effective Time as certified to Parent by
  the Company's transfer agent and registrar (the "Effective Time Outstanding
  Shares"), rounded to the nearest one ten-thousandth of a share; provided,
  however, if the average of the Daily Prices, as derived from The Wall
  Street Journal, for the ten (10) trading days immediately preceding the
  trading day prior to the Effective Time (such number rounded to the nearest
  one one-hundredth of a cent, the "Average Parent Price"), is more than
  $25.00, then the Merger Consideration Per Share shall be the greater of (i)
  6,393,298 shares of Parent Common Stock divided by the Effective Time
  Outstanding Shares and (ii) the number (rounded to the nearest one ten-
  thousandth of a share) of Parent Common Shares determined by dividing (A)
  the product of (x) 6,904,762 multiplied by (y) a fraction, the numerator of
  which is $25.00 and the denominator of which is the Average Parent Price,
  by (B) the Effective Time Outstanding Shares. The term "Daily Price" shall
  mean for each trading day the average of the opening price, high price, low
  price and closing price for the Parent Common Stock. At the Effective Time,
  all such shares of Company Common Stock shall no longer be outstanding and
  shall automatically be cancelled and retired and shall cease to exist, and
  each holder of a certificate representing any such shares shall cease to
  have any rights with respect thereto, except the right to receive the
  shares of Parent Common Stock and any cash in lieu of fractional shares of
  Parent Common Stock to be issued or paid in consideration therefor upon the
  surrender of such certificate in accordance with Section 2.2, without
  interest.
 
  Section 2.2 Exchange of Certificates.
 
    (a) Exchange Agent. Prior to the Effective Time, Parent shall deposit
  with KeyCorp Shareholder Services, Inc. or such other bank or trust company
  designated by the Company (and reasonably acceptable to Parent) (the
  "Exchange Agent"), for the benefit of the holders of shares of Company
  Common Stock, for exchange in accordance with this Article II through the
  Exchange Agent, certificates representing the shares of Parent Common Stock
  issuable pursuant to Section 2.1 in exchange for outstanding shares of
  Company Common Stock, together with cash to be paid in lieu of fractional
  shares (such shares of Parent Common Stock, together with any dividends or
  distributions with respect thereto contemplated by Section 2.2(c) and cash
  in lieu of fractional shares, being hereinafter referred to as the
  "Exchange Fund").
 
    (b) Exchange Procedures. As soon as practicable after the Effective Time,
  the Surviving Corporation shall cause the Exchange Agent to mail to each
  holder of record of a certificate or certificates which immediately prior
  to the Effective Time represented outstanding shares of Company Common
  Stock (the "Certificates") whose shares were converted pursuant to Section
  2.1 into the right to receive shares of Parent Common Stock (i) a letter of
  transmittal (which shall be in such form and have such provisions as Parent
  and the Company may reasonably specify) and (ii) instructions for
  surrendering the Certificates in exchange for certificates representing
  shares of Parent Common Stock. Upon surrender of a Certificate for
  cancellation to the Exchange Agent or to such other agent or agents as may
  be appointed by Parent, together with such letter of transmittal, duly
  executed, the holder of such Certificate shall be entitled to receive in
  exchange therefor a certificate representing that number of whole shares of
  Parent Common Stock which such holder has the right to receive pursuant to
  the provisions of this Article II and the Certificate so surrendered shall
  forthwith be cancelled. In the event of a transfer of ownership of Company
  Common Stock which is not registered in the transfer records of the
  Company, a certificate representing the proper number of shares of Parent
  Common Stock may be issued to a transferee if the Certificate representing
  such Company Common Stock is presented to the Exchange Agent, accompanied
  by all documents required to evidence and effect such transfer and by
  evidence that any applicable stock transfer taxes have been paid.
 
                                       3

 
  Until surrendered as contemplated by this Section 2.2, each Certificate
  shall be deemed at any time after the Effective Time to represent only the
  right to receive upon such surrender a certificate representing shares of
  Parent Common Stock and cash in lieu of any fractional shares of Parent
  Common Stock as contemplated by this Section 2.2.
 
    (c) Distributions with Respect to Unexchanged Shares. No dividends or
  other distributions declared or made after the Effective Time with respect
  to Parent Common Stock with a record date after the Effective Time shall be
  paid to the holder of any unsurrendered Certificate with respect to the
  shares of Parent Common Stock which such holder is entitled to receive upon
  the surrender thereof in accordance with this Section 2.2, and no cash
  payment in lieu of fractional shares shall be paid to any such holder
  pursuant to Section 2.2(e) until the holder of record of such Certificate
  shall so surrender such Certificate. Subject to the effect of applicable
  laws, following surrender of any such Certificate, there shall be paid to
  the record holder of the certificates representing whole shares of Parent
  Common Stock issued in exchange therefor, without interest, (i) at the time
  of such surrender, the amount of any cash payable in lieu of any fractional
  share of Parent Common Stock to which such holder is entitled pursuant to
  Section 2.2(e) and the amount of dividends or other distributions with a
  record date after the Effective Time theretofore paid with respect to such
  whole shares of Parent Common Stock, and (ii) at the appropriate payment
  date, the amount of dividends or other distributions with a record date
  after the Effective Time but prior to such surrender and a payment date
  subsequent to surrender payable with respect to such whole shares of Parent
  Common Stock.
 
    (d) No Further Ownership Rights in Company Common Stock. All shares of
  Parent Common Stock issued upon the surrender for exchange of shares of
  Company Common Stock in accordance with the terms hereof (including any
  cash paid pursuant to Section 2.2(c) or 2.2(e)) shall be deemed to have
  been issued in full satisfaction of all rights pertaining to such shares of
  Company Common Stock, and there shall be no further registration of
  transfers on the stock transfer books of the Surviving Corporation of the
  shares of Company Common Stock which were outstanding immediately prior to
  the Effective Time. If, after the Effective Time, Certificates are
  presented to the Surviving Corporation for any reason, they shall be
  cancelled and exchanged as provided in this Article II.
 
    (e) No Fractional Shares. No certificate or scrip representing fractional
  shares of Parent Common Stock shall be issued upon the surrender for
  exchange of Certificates, and such fractional share interests will not
  entitle the owner thereof to vote or to any rights of a stockholder of
  Parent. In lieu of any such fractional shares, each holder of Company
  Common Stock who would otherwise have been entitled to a fraction of a
  share of Parent Common Stock upon surrender of Certificates for exchange
  will be entitled to receive a cash payment in lieu of such fractional share
  in an amount equal to such fraction multiplied by the Average Parent Price.
 
    (f) Termination of Exchange Fund. Any portion of the Exchange Fund which
  remains undistributed to the stockholders of the Company for six months
  after the Effective Time shall be delivered to Parent, upon demand, and any
  stockholders of the Company who have not theretofore complied with this
  Article II shall thereafter look only to Parent for payment of their claim
  for Parent Common Stock, any cash in lieu of fractional shares of Parent
  Common Stock and any dividends or distributions with respect to Parent
  Common Stock.
 
    (g) No Liability. Neither Parent nor the Company shall be liable to any
  holder of shares of Company Common Stock or Parent Common Stock, as the
  case may be, for such shares (or dividends or distributions with respect
  thereto) or cash for payment in lieu of fractional shares delivered to a
  public official pursuant to any applicable abandoned property, escheat or
  similar law.
 
  Section 2.3 Dissenting Shares. Notwithstanding anything in this Agreement to
the contrary, shares of the Company Common Stock which immediately prior to
the Effective Time are held by stockholders who have properly exercised and
perfected appraisal rights under Section 79-4-13.02 of the MBCA (the
"Dissenting Shares") shall not be converted into the right to receive shares
of Parent Common Stock as provided in Section 2.1 hereof, but the holders of
Dissenting Shares shall be entitled to receive such consideration from the
Surviving Corporation as shall be determined pursuant to Section 79-4-13.02 of
the MBCA; provided, however, that, if
 
                                       4

 
any such holder shall have failed to perfect or shall withdraw or lose his
right to appraisal and payment under the MBCA, such holder's shares of Company
Common Stock shall thereupon be deemed to have been converted as of the
Effective Time into the right to receive shares of Parent Common Stock,

                 Representations and Warranties of the Company
 
  The Company represents and warrants to Parent and Sub as follows:
 
  Section 3.1 Organization. As used in this Agreement, any reference to the
Company and its Subsidiaries means the Company and each of its Subsidiaries;
any reference to Newco and its Subsidiaries means Newco at the time of the
Distribution and those entities that at or immediately prior to the
Distribution will be direct or indirect Subsidiaries of or merged with or
liquidated into Newco; and references to Subsidiaries of Newco mean those
entities that at or immediately prior to the Distribution will be direct or
indirect Subsidiaries of or merged with or liquidated into Newco. As used in
this Agreement, any reference to any event, change or effect having a material
adverse effect on or with respect to an entity (or group of entities taken as
a whole) means that such event, change or effect is materially adverse to the
business, properties, assets, results of operations or financial condition of
such entity (or, if with respect thereto, of such group of entities taken as a
whole). Each of the Company and its Subsidiaries is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation and has all requisite corporate power and authority to own,
lease and operate its properties and to carry on its business as now being
conducted, except where the failure to be so organized, existing and in good
standing or to have such power and authority would not have a material adverse
effect on the Retained Business taken as a whole. The Company and each of its
Subsidiaries are duly qualified or licensed to do business and in good
standing in each jurisdiction in which the property owned, leased or operated
by them or the nature of the business conducted by them makes such
qualification or licensing necessary, except where the failure to be so
qualified or licensed and in good standing would not in the aggregate have a
material adverse effect on the Retained Business taken as a whole or on the
ability of the Company and its Subsidiaries to consummate the transactions
contemplated hereby. True, accurate and complete copies of the Company's
Charter of Incorporation and bylaws, including all amendments thereto, have
heretofore been delivered to Parent.
 
  Section 3.2 Capitalization. The authorized capital stock of the Company
consists of: (i) 100,000,000 shares of Company Common Stock of which, as of
August 26, 1996, 20,621,736 shares were issued and outstanding, and (ii)
20,000,000 shares of preferred stock (the "Company Preferred Stock"), of
which, as of the date hereof, no shares are issued or outstanding. 250,000
shares of Company Preferred Stock are designated Series X Junior Participating
Preferred Stock (the "Company Series X Preferred Stock") and are reserved for
issuance in accordance with the Rights Agreement, dated as of February 27,
1996 (the "Rights Agreement"), by and between the Company and Society National
Bank, as Rights Agent (the "Company Rights Agent"), pursuant to which the
Company has issued rights (the "Company Rights") to purchase shares of Company
Series X Preferred Stock and 249,167 shares of Company Preferred Stock (with
the designations set forth in Section 3.2 of the disclosure schedule delivered
by the Company to Parent on the date hereof (the "Company Disclosure
Schedule")) are reserved for issuance pursuant to the terms of debentures
convertible into Company Preferred Stock (the "Company Convertible
Debentures") and debenture options. As of the date hereof, 926,759 shares of
Company Common Stock were reserved for issuance upon exercise of outstanding
stock options and debenture options (which debenture options are exercisable
for Company Convertible Debentures which are convertible into Company
Preferred Stock which is then convertible into Company Common Stock) and upon
conversion of Company Convertible Debentures pursuant to the Company's 1980
Long-Term Incentive Plan (the "1980 Plan"), 1988 Long-Term Incentive Plan (the
"1988 Plan") and 1995 Long-Term Incentive Plan (the "1995 Plan" and, together
with the 1980 Plan and the 1988 Plan, the "Company Stock Plans"). All the
outstanding shares of the Company's capital stock are, and all shares which
may be issued pursuant to Company
 
                                       5

 
Stock Plans will be, when issued in accordance with the terms thereof, duly
authorized, validly issued, fully paid and non-assessable and free of any
preemptive rights in respect thereof. Except as set forth above or in Section
3.2 of the Company Disclosure Schedule, as of the date hereof, there are no
existing options, warrants, calls, subscriptions or other rights or other
agreements, commitments, understandings or restrictions of any character
binding on the Company or any of its Subsidiaries with respect to the issued
or unissued capital stock of the Company or any of its Subsidiaries. Except as
set forth in Section 3.2 of the Company Disclosure Schedule, there are no
outstanding contractual obligations of the Company or any of its Subsidiaries
to repurchase, redeem or otherwise acquire any shares of capital stock of the
Company or any of its Subsidiaries.
 
  Section 3.3 Authority. The Company has the requisite corporate power and
authority to execute and deliver this Agreement and the Distribution Agreement
and to consummate the transactions contemplated hereby and thereby other than,
with respect to the Merger, the approval and adoption of this Agreement by the
affirmative vote of the holders of at least a majority of the outstanding
shares of Company Common Stock and, with respect to the Distribution, the
declaration of the Distribution by the Company's Board of Directors. The
execution, delivery and performance of this Agreement and the Distribution
Agreement by the Company and the consummation by the Company of the
Distribution and the Merger and of the other transactions contemplated hereby
and thereby have been duly authorized by the Company's Board of Directors, and
no other corporate proceedings on the part of the Company are necessary to
authorize this Agreement or the Distribution Agreement or for the Company to
consummate the transactions so contemplated hereby or thereby other than, with
respect to the Merger, the approval and adoption of this Agreement by the
affirmative vote of the holders of at least a majority of the outstanding
shares of Company Common Stock and, with respect to the Distribution,
declaration of the Distribution by the Company's Board of Directors. This
Agreement has been duly executed and delivered by the Company and, assuming
this Agreement constitutes a valid and binding obligation of Parent and Sub,
constitutes a valid and binding obligation of the Company, enforceable against
the Company in accordance with its terms. Prior to the Distribution, the
Distribution Agreement will be duly executed and delivered by each of the
Company and Newco and upon such execution and delivery will constitute a valid
and binding obligation of each of the Company and Newco, enforceable against
each of them in accordance with its terms.
 
  Section 3.4 Consents and Approvals; No Violations. Except (a) as set forth

Subsidiaries, none of the execution, delivery or performance of this Agreement
or the Distribution Agreement by the Company or the consummation by the
Company of the transactions contemplated hereby or thereby and compliance by
the Company with any of the provisions hereof or thereof will (i) conflict
with or result in any breach of any provisions of the charters or bylaws of
the Company or of any of its Subsidiaries, (ii) require any filing by the
Company or any of its Subsidiaries with, or any permit, authorization, consent
or approval to be obtained by the Company or any of its Subsidiaries of, any

Entity"), (iii) result in a violation or breach of, or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any
right of termination, amendment, cancellation or acceleration) under, any of
the terms, conditions or provisions of any note, bond, mortgage, indenture,
lease, license, contract, agreement or other instrument, obligation or

("Contracts") or (iv) violate any order, writ, injunction, decree, statute,
rule or regulation applicable to the Company or any of its Subsidiaries,

  accordance with generally accepted accounting principles on a basis
  consistent with the Company Financial Statements, and, except as set forth
  in Section 3.7 of the Company Disclosure Schedule, fairly present in all
  material respects (subject to normal audit adjustments) the consolidated
  financial position of the Company and its Subsidiaries as at the date
  thereof, after giving pro forma effect to the Distribution (assuming the

  their operations for the one-year period then ended, after giving pro forma
  effect to the Distribution (assuming the Distribution occurred on July 1,
  1995).
 
    (c) At the Effective Time, except for the Excluded Assets and as
  contemplated by this Agreement or the Distribution Agreement, neither Newco
  nor any of its Subsidiaries will own or have rights to use any of the
  assets or property, whether tangible, intangible or mixed, which are
  necessary for the conduct of the Retained Business as conducted on the date
  hereof. Except as set forth in Section 3.7 of the Company Disclosure
  Schedule, at the Effective Time neither Newco nor any of its Subsidiaries
  will be a party to any material agreement or arrangement with the Surviving
  Corporation or any of its Subsidiaries (other than the Distribution
  Agreement and any agreements contemplated by the Distribution Agreement,
  including the Tax Disaffiliation Agreement and the Employee Benefits
  Agreement).
 
  Section 3.8 Litigation. Except as disclosed in the Company SEC Documents
filed prior to the date hereof or as set forth in Section 3.8 of the Company
Disclosure Schedule and except with respect to information concerning Triad,
as to which the Company makes no representation or warranty for purposes of
this Section 3.8, there is no suit, action, proceeding or investigation
relating to the Retained Business pending or, to the knowledge of the Company,
threatened, against the Company or any of its Subsidiaries before any
Governmental Entity which, individually or in the aggregate, is reasonably
likely to have a material adverse effect on the Retained Business taken as a
whole or the ability of the Company to consummate the transactions
contemplated hereby. Except as disclosed in the Company SEC Documents filed
prior to the date hereof or as set forth in Section 3.8 of the Company
Disclosure Schedule, neither the Company nor any of its Subsidiaries is
subject to any outstanding order, writ, injunction or decree relating to the
Retained Business which, individually or in the aggregate, is reasonably
likely to have a material adverse effect on the Retained Business taken as a
whole or a material adverse effect on the ability of the Company to consummate
the transactions contemplated hereby.
 
  Section 3.9 Employee Benefits.
 
    (a) Other than with respect to Triad, as to which the Company makes no
  representation or warranty for purposes of this Section 3.9, Section 3.9 of
  the Company Disclosure Schedule contains a list of all "employee benefit
  plans" within the meaning of Section 3(3) of the Employee Retirement Income
  Security Act of 1974, as amended ("ERISA"), and all bonus, stock option,
  fringe benefit, vacation, incentive, severance, employment or other benefit
  plans, programs, agreements and arrangements (the "Benefit
 
                                       8

 
  Plans"), which cover employees or former employees of the Company and its
  Subsidiaries who are or were employed in the Retained Business (the
  "Employees"). True and complete copies of all Benefit Plans, any trust
  instruments and/or insurance contracts, if any, forming a part of any such
  plans, and all amendments thereto; current summary plan descriptions; where
  applicable, the most current determination letter received from the
  Internal Revenue Service (the "Service") and most recent determination
  letter application; and where applicable, annual reports, financial
  statements and actuarial reports for the last three plan years, which
  fairly and accurately reflect the financial condition of the plans have
  been made available to Parent.
 
    (b) All Benefit Plans are in compliance with ERISA, the Code and all
  other applicable laws in all material respects. Each Benefit Plan which is
  an "employee pension benefit plan" within the meaning of Section 3(2) of
  ERISA (a "Pension Plan") and which is intended to be qualified under
  Section 401(a) of the Code has received a favorable determination letter
  from the Service, and the Company is not aware of any circumstances likely
  to result in revocation of any such favorable determination letter. Neither
  the Company nor any of its Subsidiaries or any ERISA Affiliate (as defined
  below) has contributed or been required to contribute to any Multiemployer
  Plan (as defined in ERISA) with respect to any Employees.
 
    (c) No liability under Subtitle C or D of Title IV of ERISA has been
  incurred by the Company or any Subsidiary with respect to any ongoing,
  frozen or terminated Benefit Plan, currently or formerly maintained by any
  of them, or the Plan of any entity which is or has been considered one
  employer with the Company under Section 4001 of ERISA or Section 414 of the
  Code (an "ERISA Affiliate") which would have a material adverse effect on
  the Retained Business taken as a whole.
 
    (d) All contributions required to be made or accrued as of June 30, 1996
  under the terms of any Benefit Plan for which the Surviving Corporation or
  any of its Subsidiaries may have liability have been timely made or have
  been reflected on the Retained Business Balance sheet. Neither any Pension
  Plan nor any single-employer plan of an ERISA Affiliate has incurred an
  "accumulated funding deficiency" (whether or not waived) within the meaning
  of Section 412 of the Code or Section 302 of ERISA in an amount which would
  have a material adverse effect on the Retained Business taken as a whole.
  Neither the Company nor any of its Subsidiaries has provided, or is
  required to provide, security to any Pension Plan pursuant to Section
  401(a)(29) of the Code.
 
    (e) Neither the Company nor any of its Subsidiaries has any obligations
  for retiree health and life benefits for Employees or former Employees
  under any Benefit Plan, except as set forth in Section 3.9 of the Company
  Disclosure Schedule or as required by Part 6 of Title I of ERISA.
 
    (f) The Company and its Subsidiaries have no unfunded liabilities with
  respect to any Pension Plan which covers former Employees in an amount
  which would have a material adverse effect on the Retained Business taken
  as a whole.
 
    (g) Immediately after the Effective Time, the Surviving Corporation or
  its Subsidiaries could terminate each Benefit Plan in accordance with its
  terms without incurring any material liability.
 
    (h) With respect to the Company and the Retained Business, the
  transactions contemplated by this Agreement and the Distribution Agreement
  will not cause any additional payments to be due under any Benefit Plan,
  nor accelerate the payment or vesting of any amounts due under any Benefit
  Plan, nor result in any excess parachute payment within the meaning of Code
  Section 280G except for payments which are paid prior to the Effective
  Time, accrued on the Audited Closing Balance Sheet (as defined in Section
  6.13) or for which funds have been reserved, or amounts due which are
  assumed by Newco pursuant to the Distribution Agreement.
 
  Section 3.10 Absence of Certain Changes or Events. Since June 30, 1996, the
Company and its Subsidiaries have conducted the Retained Business only in the
ordinary and usual course consistent with past practice, except as set forth
in Section 3.10 of the Company Disclosure Schedule, and there has not been any
change or development, or combination of changes or developments which
individually or in the aggregate have had or are reasonably likely to have a
material adverse effect on the Retained Business taken as a whole.

investigation with respect to or has been given notice or been charged by any
Governmental Entity with any violation of, any law, statute, order, rule,
regulation or judgment of any Governmental Entity, except for violations
which, in the aggregate, would not have a material adverse effect on the
Retained Business taken as a whole. The Company and its Subsidiaries have all
permits, licenses, franchises and other governmental authorizations, consents
and approvals necessary to conduct the Retained Business as presently
conducted, except for any such permits, licenses, franchises or other
governmental authorizations, consents and approvals the failure of which to
have would not have a material adverse effect on the Retained Business taken
as a whole.

authority to own, lease and operate its properties and to carry on its
business as now being conducted except

where the failure to be so organized, existing and in good standing or to have
such power and authority would not have a material adverse effect on Parent
and its Subsidiaries taken as a whole. Parent and each of its Subsidiaries are
duly qualified or licensed to do business and in good standing in each
jurisdiction in which the property owned, leased or operated by them or the
nature of the business conducted by them makes such qualification or licensing
necessary, except where the failure to be so duly qualified or licensed and in
good standing would not in the aggregate have a material adverse effect on
Parent and its Subsidiaries taken as a whole or on the ability of Parent or
Sub to consummate the transactions contemplated hereby. True, accurate and
complete copies of Parent's and Sub's Articles of Incorporation and bylaws,
including all amendments thereto, have heretofore been delivered to the
Company.
 
  Section 4.2 Capitalization. As of the date hereof, the authorized capital
stock of Parent consists of: (i) 100,000,000 shares of Parent Common Stock of

1,550,000 shares were held in treasury, and (ii) 500,000 shares of preferred
stock, par value $0.01 per share, of which, as of the date hereof, no shares

Parent Preferred Stock are designated Preferred Stock, Series A and are
reserved for issuance in accordance with the Rights Agreement, dated as of
August 8, 1994, by and between Parent and Harris Trust and Savings Bank, as
Rights Agent, pursuant to which Parent has issued rights to purchase shares of
Parent Preferred Stock. All the outstanding shares of Parent's capital stock
are, and all shares of Parent Common Stock which are to be issued pursuant to
the Merger will be when issued in accordance with the terms hereof, duly
authorized, validly issued, fully paid and nonassessable and free of any
preemptive rights in respect thereto. Except for Parent Common Stock issuable
to directors, officers and employees pursuant to Parent stock option and other
benefit plans and except for this Agreement, there are no existing options,
warrants, calls, subscriptions or other rights or other agreements,
commitments, understandings or restrictions of any character relating to the
issued or unissued capital stock of Parent or any of its Subsidiaries. As of
the date hereof, the authorized capital stock of Sub consists of 1,000 shares
of Common Stock, par value $0.01 per share, all of which are validly issued,

of shares of Parent Common Stock have been issued except issuances of shares
reserved for issuance as described above.
 
  Section 4.3 Authority. Parent and Sub have the requisite corporate power and

of at least a majority of the shares of Parent Common Stock present, in person
or by proxy, and entitled to vote at the meeting of Parent's stockholders
referred to in Section 6.3(b) for which a quorum exists). The execution,
delivery and performance of this Agreement by each of Parent and Sub and the
consummation by Sub of the Merger and by Parent and Sub of the other
transactions contemplated hereby have been duly authorized by the Boards of
Directors of Parent and Sub and Parent as the sole stockholder of Sub, and no
other corporate proceedings on the part of Parent or Sub are necessary to
authorize this Agreement or for Parent and Sub to consummate the transactions
so contemplated (other than, with respect to the Merger, the approval of the
issuance of shares of Parent Common Stock to the Company's stockholders
pursuant to this Agreement by an affirmative vote of the holders of at least a
majority of the shares of Parent Common Stock present, in person or by proxy,
and entitled to vote at the meeting of Parent's stockholders referred to in
Section 6.3(b) for which a quorum exists). This Agreement has been duly
executed and delivered by each of Parent and Sub, and, assuming this Agreement
constitutes a valid and binding obligation of the Company, constitutes a valid
and binding obligation of each of Parent and Sub, enforceable against each of
them in accordance with its terms.

  Incorporation or bylaws in a manner adverse to the Company or otherwise
  inconsistent with the transactions contemplated hereby.
 
    (e) Indebtedness. Parent shall not, nor shall it permit any of its

  into credit agreements, lines of credit or similar arrangements until
  borrowings are made under such arrangements or (ii) refinancings of
  existing indebtedness) any indebtedness for borrowed money or guarantee any
  such indebtedness or issue or sell any debt securities or warrants or
  rights to acquire any debt securities of Parent or any of its Subsidiaries
  or guarantee any obligations of others other than (w) in the ordinary
  course of business consistent with past practice, (x) pursuant to existing
  credit or guaranty agreements, (y) the Financing (as defined in Section
  6.14) or (z) additional indebtedness not to exceed $50,000,000 in the
  aggregate.
 
    (f) Filings. Parent shall promptly provide the Company (or its counsel)

    (h) Cooperation. Parent shall not take, nor permit Sub or any of its
  other Subsidiaries to take, any action that would or is reasonably likely
  to result in any of the conditions to the Merger set forth in Article VII

  materially delay such consummation, and Parent shall promptly advise the
  Company orally and in writing of any change in, or event with respect to,
  the business or operations of Parent having, or which, insofar as can
  reasonably be foreseen, could have, a material adverse effect on Parent and
  its Subsidiaries taken as a whole.

  Section 6.2 Access to Information. Upon reasonable notice, each of the
Company and Parent shall (and shall cause its Subsidiaries to) afford to the
officers, employees, accountants, counsel and other representatives of the
other party, access, during normal business hours during the period prior to
the Effective Time, to all its properties, books, contracts, commitments and
records (with respect to the Company, to the extent relating to the Retained
Business), and, during such period, each of the Company and Parent shall (and
shall cause each of their respective Subsidiaries to) furnish promptly to the
other (a) a copy of each report, schedule, registration statement and other

Corporation and its Subsidiaries to afford to the officers, employees,
accountants, counsel and other representatives of Newco access, during normal
business hours, to the Surviving Corporation's and its Subsidiaries' books and

                                      19

 
  Section 6.3 Stockholders Meetings.
 
    (a) The Company shall call a meeting of its stockholders to be held as
  promptly as practicable for the purpose of voting upon the approval and
  adoption of this Agreement. The Company will, through its Board of
  Directors, recommend to its stockholders approval and adoption of this
  Agreement and, if the Company determines such approval to be necessary or
  appropriate, the Distribution and shall use all reasonable efforts to hold
  such meeting as soon as practicable after the date hereof; provided,
  however, that the Board of Directors of the Company may fail to make such a
  recommendation, or withdraw, modify or change any such recommendation if it
  determines after receiving the advice of outside counsel that making such
  recommendation, or that the failure to withdraw, modify or change its
  recommendation, would be inconsistent with its fiduciary duties under
  applicable law.
 
    (b) Parent shall call a meeting of its stockholders to be held as
  promptly as practicable for the purpose of voting upon the approval of the
  issuance of the shares of Parent Common Stock to the Company's stockholders
  pursuant to this Agreement. Parent will, through its Board of Directors,
  recommend to its stockholders such approval and shall use all reasonable
  efforts to hold such meeting as soon as practicable after the date hereof;
  provided, however, that the Board of Directors of Parent may fail to make
  such a recommendation, or withdraw, modify or change any such
  recommendation if it determines after receiving the advice of outside
  counsel that making such recommendation, or that the failure to withdraw,
  modify or change its recommendation, would be inconsistent with its
  fiduciary duties under applicable law.
 
  Section 6.4 Legal Conditions to Distribution and Merger. Each of the
Company, Parent and Sub will use all reasonable efforts to comply promptly
with all legal requirements which may be imposed on it or its respective
Subsidiaries with respect to the Distribution and the Merger (which actions
shall include, without limitation, furnishing all information required under
the HSR Act and will promptly cooperate with and furnish information to each
other in connection with any such requirements imposed upon any of them or any
of their respective Subsidiaries in connection with the Distribution or the
Merger). Subject to the terms and conditions hereof, each of the Company,
Parent and Sub will, and will cause its Subsidiaries to, promptly use all
reasonable efforts to obtain (and will consult and cooperate with each other
in obtaining) any consent, authorization, order or approval of, or any
exemption by, any Governmental Entity or other public or private third party,
required to be obtained or made by such party in connection with the
Distribution or the Merger or the taking of any action contemplated thereby or
by this Agreement or the Distribution Agreement.
 
  Section 6.5 Stock Exchange Listing. Parent shall use all reasonable efforts
to cause the shares of Parent Common Stock to be issued in the Merger to be
approved for listing on either the NYSE or the NASDAQ National Market System,
depending on where the Parent Common Stock is listed as of the Effective Time,
and any other securities exchange on which shares of Parent Common Stock may
at such time be listed, subject to official notice of issuance, prior to the
Closing Date.
 
  Section 6.6 Company Severance Obligations. Subject to the proviso in the
following sentence, the Company will pay with the proceeds of the Financing
(as defined in Section 6.14) or Newco will assume the transaction bonus and
severance payments arising out of the transactions contemplated by this
Agreement pursuant to any contract, agreement or arrangement of which the
Company or any of its Subsidiaries is a party, including, without limitation,
payments pursuant to the agreements listed in Section 6.6 of the Company
Disclosure Schedule. In no event shall Parent, any of its Subsidiaries or the
Surviving Corporation be responsible for any such payments, or be under any
obligation to honor or assume any such obligations; provided, however, Parent
and the Surviving Corporation shall assume and retain, with respect to the
Retained Employees (as defined in Section 6.7), any and all severance
obligations that arise due to events or actions occurring after the Effective
Time.
 
  Section 6.7 Employee Matters; Company Stock Plans.
 
    (a) The Company and Parent agree that Parent will, to the extent
  practicable, immediately after the Effective Time and for at least six (6)
  months thereafter, permit the operating personnel of the Retained
 
                                      20

 
  Business and the other Company employees listed in Section 6.7 to the
  Parent Disclosure Schedule who will remain in the employ of the Surviving
  Corporation after the Effective Time (collectively, the "Retained
  Employees") (i) to participate in a group health plan of Parent, or one of
  its Subsidiaries that similarly situated employees of Parent participate,
  in accordance with the terms of the plan and, subject to the approval of
  its stop-loss carrier on reasonable terms and subject to applicable legal
  requirements, to waive any pre-existing condition clause or waiting period
  requirement in such group health plan and to give credit for deductible
  amounts paid by a Retained Employee during the current deductible year of
  such group health plan while employed by the Company; (ii) to participate
  in and receive credit under tax qualified retirement plans of Parent or any
  of its Subsidiaries that similarly situated employees of Parent
  participate, for which they are otherwise eligible, solely for eligibility
  and vesting purposes, for their service with the Company, to the extent
  permitted by applicable tax-qualification requirements; and (iii) to
  participate in other benefit plans of Parent which are offered to similarly
  situated employees.
 
    (b) Effective as of the Effective Time, each outstanding option to
  purchase shares of Company Common Stock or to purchase Company Convertible
  Debentures (a "Company Option") held by a Retained Employee under the
  Company Stock Plans whether vested or unvested, exercisable or
  unexercisable, shall be exchanged for an option (a "Parent Option") to
  purchase the number of shares of Parent Common Stock equal to the product
  of (1) the quotient of (x) the Average Company Stock Price, and (y) the
  Average Parent Stock Price (the "Conversion Ratio") and (2) the number of
  shares of Company Common Stock that the holder of such option would have
  been entitled to receive had such holder exercised such option in full and
  in the case of a Company Option exercisable for Company Convertible
  Debentures, converted such convertible debentures into Company Preferred
  Stock and then into Company Common Stock, (not taking into account whether
  or not such option or convertible debenture was in fact exercisable)
  (rounded to the nearest whole share) at an exercise price equal to the per
  share exercise price of such Company Options divided by the Conversion
  Ratio (rounded to the nearest cent), which Parent Option shall be subject
  to the same terms and conditions (including the vesting schedule) as the
  Company Option; provided, however, that the Parent Option shall be
  exercisable only for Parent Common Stock. The obligations of the Company
  with respect to such Parent Options shall be transferred to and assumed by
  Parent. For purposes of this Section 6.7(b), (i) "Average Parent Stock
  Price" shall mean the average of the closing prices of the Parent Common
  Stock on the New York Stock Exchange Composite Transactions Reporting
  System or the NASDAQ National Market System, as the case may be, as
  reported by The Wall Street Journal, for the 10 trading days immediately
  proceeding the trading day prior to the date that the Company Common Stock
  commences trading on an x-dividend basis with respect to the Distribution
  (the "Measuring Period") and (ii) "Average Company Stock Price" shall mean
  the average of the closing prices of the Company Common Stock on the New
  York Stock Exchange Composite Transactions Reporting System, as reported by
  The Wall Street Journal, for the Measuring Period.
 
    (c) As soon as practicable after the Effective Time, Parent shall deliver
  to the Retained Employees having options exchanged pursuant to Section
  6.7(b) above appropriate notices setting forth their rights pursuant
  thereto.
 
    (d) Parent shall take all corporate action necessary to reserve for
  issuance a sufficient number of shares of Parent Common Stock for delivery
  under the options converted in accordance with this Section 6.7. As soon as
  practicable after the Effective Time, Parent shall file a registration
  statement on Form S-3 or Form S-8, as appropriate (or any successor or
  other appropriate forms), or another appropriate form with respect to the
  shares of Parent Common Stock subject to such options or, to the extent
  required by law or in accordance with past practice, awards and shall use
  its best efforts to maintain the effectiveness of such registration
  statement or registration statements (and maintain the current status of
  the prospectus or prospectuses contained therein) for so long as such
  options or awards remain outstanding. With respect to those individuals who
  subsequent to the Merger will be subject to the reporting requirements
  under Section 16(a) of the Exchange Act, where applicable, Parent shall
  administer the options exchanged pursuant to this Section 6.7 in a manner
  that complies with Rule 16b-3 promulgated under the Exchange Act to the
  extent the applicable options complied with such rule prior to the Merger.
 
                                      21

 
    (e) Nothing in this Agreement shall be construed to require Parent or the
  Company to continue the employment of any Retained Employee for any period
  of time, or, except as required by Section 6.7(a) above, to offer any
  particular type or level of benefits to any employee. Nothing in this
  Agreement shall prevent Parent or the Company from disciplining or
  terminating any Retained Employee or from amending or terminating any
  benefit plans at any time.
 
  Section 6.8 Fees and Expenses. Subject to the Distribution Agreement,
whether or not the Merger is consummated and except as otherwise provided
herein, all fees, costs and expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be paid by the party
incurring such expenses; provided, however, that Parent and the Company shall
each pay one-half of the printing costs incurred with respect to the S-4 and
the Proxy Statement.
 
  Section 6.9 Indemnification.
 
    (a) The Company shall, and from and after the Effective Time the
  Surviving Corporation shall, indemnify, defend and hold harmless each
  person who is now, or has been at any time prior to the date of this
  Agreement or who becomes prior to the Effective Time, an officer, director
  or employee of the Company or any of its Subsidiaries (the "Indemnified
  Parties") against all losses, claims, damages, costs, expenses, liabilities
  or judgments, or amounts that are paid in settlement with the approval of
  the indemnifying party (which approval shall not be unreasonably withheld)
  of, or in connection with, any claim, action, suit, proceeding or
  investigation to the extent related to, or to the extent arising from, the
  Retained Business and based in whole or in part on or arising in whole or
  in part out of the fact that such person is or was a director, officer or
  employee of the Company or any of its Subsidiaries, whether pertaining to
  any matter existing or occurring at or prior to the Effective Time and
  whether asserted or claimed prior to, or at or after, the Effective Time
  ("Indemnified Liabilities"), in each case to the full extent a corporation
  is permitted under the MBCA (notwithstanding the bylaws of the Company or
  the Surviving Corporation) to indemnify its own directors, officers and
  employees, as the case may be (and the Surviving Corporation will pay
  expenses in advance of the final disposition of any such action or
  proceeding to each Indemnified Party to the full extent permitted by law
  upon receipt of any affirmation and undertaking contemplated by Section
  8.53 of the MBCA). Without limiting the foregoing, in the event any such
  claim, action, suit, proceeding or investigation is brought against any
  Indemnified Party (whether arising before or after the Effective Time), (i)
  the Indemnified Parties may retain counsel satisfactory to them with the
  consent of the Company (or the consent of the Surviving Corporation after
  the Effective Time) which consent of the Company (or, after the Effective
  Time, the Surviving Corporation) with respect to such counsel retained by
  the Indemnified Parties may not be unreasonably withheld, (ii) the Company
  (or after the Effective Time, the Surviving Corporation) shall pay all
  reasonable fees and expenses of such counsel for the Indemnified Parties
  promptly as statements therefor are received, and (iii) the Company (or
  after the Effective Time, the Surviving Corporation) will use all
  reasonable efforts to assist in the vigorous defense of any such matter,
  provided that neither the Company nor the Surviving Corporation shall be
  liable for any settlement of any claim effected without its written
  consent, which consent, however, shall not be unreasonably withheld. Any
  Indemnified Party wishing to claim indemnification under this Section 6.9,
  upon learning of any such claim, action, suit, proceeding or investigation,
  shall notify the Company or the Surviving Corporation (but the failure so
  to notify shall not relieve the Company or the Surviving Corporation from
  any liability which it may have under this Section 6.9 except to the extent
  such failure materially prejudices such party), and shall deliver to the
  Company (or after the Effective Time, the Surviving Corporation) the
  affirmation and undertaking contemplated by Section 8.53 of the MBCA. The
  Indemnified Parties as a group may retain only one law firm to represent
  them with respect to each such matter unless there is, under applicable
  standards of professional conduct, a conflict on any significant issue
  between the positions of any two or more Indemnified Parties.
 
    (b) The provisions of this Section 6.9 are intended to be for the benefit
  of, and shall be enforceable by, each Indemnified Party, his or her heirs
  and representatives.
 
                                      22

 
  Section 6.10 No Solicitations. The Company will immediately cease any
existing discussions or negotiations conducted prior to the date hereof with
respect to any merger, consolidation, business combination, sale of a
significant amount of assets outside of the ordinary course of business, sale
of shares of capital stock outside of the ordinary course of business, tender
or exchange offer, spin-off, recapitalization or similar transaction involving
the sale of the Company or any of its Subsidiaries or divisions but excluding
those potential transactions set forth in Section 6.10 of the Company
Disclosure Schedule (an "Acquisition Transaction"). The Company, its
Subsidiaries and their respective directors and officers shall not, and its or
its Subsidiaries' affiliates, representatives and agents shall not, directly
or indirectly, solicit any person, entity or group concerning any Acquisition
Transaction (other than the transactions contemplated by this Agreement);
provided that the Company may (i) furnish information or enter into
negotiations to the extent the Company's Board of Directors determines after
receiving the advice of outside counsel that the failure to do so would be
inconsistent with its fiduciary duties under applicable law and prior to
furnishing such information to, or entering into discussions or negotiations
with such person, entity or group the Company (x) provides immediate written
notice to Parent to the effect that it is furnishing information to, or
entering into discussions or negotiations with, such person, entity or group,
and (y) either enters into with such person, entity or group a confidentiality
agreement in reasonable, customary form on terms not more favorable to such
person, entity or group than the terms contained in the Confidentiality
Agreement or releases Parent from the standstill provisions of the
Confidentiality Agreement not applicable to such person; and (ii) recommend to
its stockholders a bona fide transaction or combination of transactions that
the Board of Directors determines after consulting with its legal and other
advisors is more favorable, from a financial point of view, to the
stockholders of the Company than the Distribution and the Merger (a "Higher
Proposal"). The Company agrees not to release any third party from its
obligations, or grant any consent, under any existing standstill provision
relating to any Acquisition Transaction or otherwise under any confidentiality
or other agreement without similarly releasing or granting a consent to Parent
under the Confidentiality Agreement.
 
  Section 6.11 Distribution. Prior to the Closing, the Company will enter into
the Distribution Agreement in the form attached hereto with such changes which
are not adverse to Parent and Sub and cause Newco to enter into the
Distribution Agreement and the Company will take all action necessary to
effect the Distribution pursuant to the terms of the Distribution Agreement.
 
  Section 6.12 Tax-Free Nature of Transactions. Each party agrees to report
the Transfer as a tax-free transaction under Section 332, 351 or 368(a) of the
Code, the Distribution as a tax-free distribution under Section 355 of the
Code and the Merger as a tax-free reorganization within the meaning of Section
368(a)(1)(B) of the Code on all Tax Returns and other filings, and take no
position inconsistent therewith. The parties shall not, and shall not permit
any of their respective Subsidiaries to, take or cause or permit to be taken,
any action that would disqualify the Distribution as a tax-free distribution
under Section 355 of the Code, disqualify the Transfer as a tax-free
transaction under Section 332, 351 or 368(a) or disqualify the Merger as a
reorganization within the meaning of Section 368(a)(1)(B) of the Code,
excluding any action to be taken pursuant to this Agreement to effect the
Merger.
 
  Section 6.13 Audited Closing Balance Sheet. No later than 45 days after the
Effective Date, Newco shall deliver to Parent an audited consolidated balance
sheet for the Retained Business at the earlier of the Effective Date or
December 31, 1996 after giving effect to the Distribution (but not to the
Financing (as defined in Section 6.14) or the Merger), which shall be audited
by Newco's independent public accountants as in accordance with generally
accepted auditing standards (the "Audited Closing Balance Sheet"). The Audited
Closing Balance Sheet shall be prepared in accordance with generally accepted
accounting principles on a basis consistent with the Company Financial
Statements. To the extent that the net working capital (current assets less
current liabilities) of the Retained Business as shown on the Audited Closing
Balance Sheet is more or less than the estimated net working capital as of the
Effective Date certified pursuant to Section 6.14, the Company shall pay to
Newco, or Newco shall pay to the Company, the amount of such excess or
shortfall, respectively, in cash within five days of the delivery of the
Audited Closing Balance Sheet. The Company agrees that representatives of
Parent and Newco shall be given access to all work papers, books, records and
other information related to
 
                                      23

 
the preparation of the Audited Closing Balance Sheet. In addition, the Company
will authorize, and will use all reasonable efforts to provide Parent and
Newco with access to all work papers of the Company's independent public
accountants in connection with or relating to their audit of the Audited
Closing Balance Sheet.
 
  Section 6.14 Financing. Parent will use its best efforts to assist the
Company in arranging a customary bank facility for the Company that will be
funded immediately prior to the Time of Distribution (as defined in the
Distribution Agreement) (the "Financing"). The Financing will be in an
aggregate amount equal to $150,000,000 plus (i) the product of (x) the lesser
of (A) $2.00 and (B) the amount, if any, by which the Average Parent Price is
less than $19.00 times (y) 6,904,762, plus (ii) the costs of obtaining the
Financing (including, without limitation, any commitment or agent fees,
reasonable attorney fees or other costs and expenses associated with the
Financing), plus (iii) the product of (x) $56,575 times (y) the number of
calendar days by which the Effective Date is after December 31, 1996, plus
(iv) the net cash used by the Retained Business after December 31, 1996
through the Effective Date, minus (v) the unpaid balance as of the Effective
Date of the AMPRO Retrofit due under the Kellogg Agreement (as defined in
Section 6.15) (which unpaid balance as of July 31, 1996 is set forth in
Section 6.15 of the Company Disclosure Schedule), plus or minus (vi) the
amount by which the estimated net working capital of the Retained Business as
of the earlier of the Effective Date or December 31, 1996 as certified by the
chief financial officer of the Company is more or less, respectively, than
$8,000,000. Without qualifying Parent's obligations pursuant to the last
sentence of this Section 6.14, the Financing will be on terms that are
acceptable to Parent. The parties agree that the proceeds of the Financing
will be used to refinance in full all outstanding debt of the Retained
Business (other than accounts payable incurred in the ordinary course of the
Retained Business), as well as any and all transaction, severance and other
costs payable by the Company in connection with the transactions contemplated
by this Agreement. To the extent that the proceeds of the Financing are not
fully applied as set forth above, any remaining proceeds may be contributed to
Newco at the discretion of the Company. The Company shall be responsible for
the costs of obtaining the Financing (including, without limitation, any
commitment or agent fees, reasonable attorney fees or other costs and expenses
associated with the Financing), although the parties recognize that Parent
will incur costs related to the Financing in connection with satisfying itself
as to the terms and conditions of the Financing. In the event that the
Company's stockholders do not approve the Merger, the Distribution and the
other transactions contemplated by this Agreement, the Company and Parent will
reimburse each other for one-half of any costs incurred by them in connection
with the Financing. In the event this Agreement is terminated for any other
reason, Parent shall be responsible for and reimburse the Company for any
costs reasonably incurred in connection with the Financing. In the event that
the Company is unable to arrange a bank facility for the Financing, Parent
will be responsible for arranging alternative funds from an independent,
unrelated third party for the Financing.
 
  Section 6.15 AMPRO Facility. The Company shall use all reasonable efforts to
cause the capital improvements to the Company's AMPRO Facility currently in
progress (the "AMPRO Retrofit") as set forth in that certain contract dated
September 7, 1995 between the Company and M.W. Kellogg (the "Kellogg
Agreement") to be completed (including plant shutdowns, tie-ins and resumption
of operations) by December 31, 1996 (with performance testing to be completed
after December 31, 1996) on the terms and conditions set forth in the Kellogg
Agreement. Section 6.15 of the Company Disclosure Schedule sets forth the
unpaid balance of the cost of completion of the AMPRO Retrofit as of July 31,
1996 under the Kellogg Agreement. If despite the Company's reasonable efforts,
the AMPRO Retrofit is not mechanically complete and ready for tie-ins to be
made during the time of turnaround scheduled for December 1, 1996 through
December 15, 1996 then the turnaround shall be delayed until such time as the
AMPRO Retrofit can be mechanically completed and made ready for tie-ins during
the turnaround period.
 
  Section 6.16 Comfort Letters.
 
    (a) The Company shall use all reasonable efforts to cause KPMG Peat
  Marwick LLP, the Company's independent public accountants, to deliver a
  letter dated as of the date of the Proxy Statement, and addressed to itself
  and Parent and their respective Boards of Directors, in form and substance
  reasonably satisfactory to Parent, and customary in scope and substance for
  agreed-upon procedures letters delivered by
 
                                      24

 
  independent public accountants in connection with registration statements
  and proxy statements similar to the S-4 and the Proxy Statement.
 
    (b) Parent shall use all reasonable efforts to cause Arthur Andersen &
  Co., the Parent's independent public accountants, to deliver a letter dated
  as of the date of the Proxy Statement, and addressed to itself and the
  Company and their respective Boards of Directors, in form and substance
  reasonably satisfactory to the Company, and customary in scope and
  substance for agreed-upon procedures letters delivered by independent
