     1.2 Purchase Price and Payment. At the Closing, Buyer shall, upon the
surrender by each Stockholder of the certificate(s) representing the Company
Shares and in exchange for the sale by such Stockholder of the Company Shares,
pay $11,080,730, such amount being the aggregate cash amount owing to the
Stockholders hereunder, to an account established by the Company, as agent, on
behalf of the Stockholders and Buyer shall deliver to each Stockholder an amount
of 11% junior subordinated debentures of Buyer, due 2007 in the form of Exhibit

forth following such Stockholder's name on Exhibit A attached hereto. At the
closing, the Company shall pay to each Stockholder (i) the amounts of cash as
set forth following such Stockholder's name under the heading "Consideration to

documents relating to the Senior Debt (as such term is defined in the Notes as
provided for, and subject to the limitations set forth, in this Section 1.4). If
a Prepayment Date is the same as the date on which interest is due and payable
on the Notes and Deferred Obligations, then the amounts to be prepaid on such
Prepayment Date shall be allocated and paid, pro rata among the Notes and
Deferred Obligations, in the following priority: (i) first, to pay all interest
due and payable on the Notes and Deferred Obligations on such Prepayment Date;
(ii) second, to pay any remaining principal on any Series A Secondary Notes or
the corresponding obligations under the Deferred Obligations then outstanding;
and (iii) third, to pay the remaining "Prepayment Principal Amount" (as such
term is defined in the Notes) of any Notes or Deferred Obligations then

interest is due and payable on the Notes and Deferred Obligations, then the
amounts to be prepaid on such Prepayment Date shall be allocated and paid, pro
rata among the Notes and Deferred Obligations, in the following priority: (W)
first, to pay all interest accrued but not yet paid on the Series A Secondary
Notes or the corresponding obligations under the Deferred Obligations; (X)
second, to pay all interest accrued but not yet paid on the remaining Prepayment
Principal Amount or; (Y) third, to pay any remaining principal on any Series A
Secondary Notes or the corresponding obligations under the Deferred Obligations;
and (Z)

fourth, to pay the remaining Prepayment Principal Amount. The total amount of 
all payments pursuant to subsection (iii) and subsection (Z) shall not exceed 
$2,500,000.
 
     1.5 Stockholders' Representative.
 
         (a) In order to administer efficiently (i) the implementation of the
Agreement by certain of the Stockholders, (ii) the waiver of any condition to
the obligations of such Stockholders, and (iii) the settlement of any dispute
with respect to the Agreement, the Former Management Stockholders, the
Management Holders and the Berkshire Stockholders, with the exception of
Berkshire and Berkshire Partners, (the "Designating Stockholders") hereby
designate Russell L. Epker as their representative (the "Stockholders'
Representative").
 
         (b) The Designating Stockholders hereby authorize the Stockholders'
Representative (i) to take all action necessary in connection with the
implementation of the Agreement on behalf of the Designating Stockholders and
the settlement of any dispute, (ii) to give and receive all notices required to
be given under the Agreement with respect to the Designating Stockholders and
(iii) to take any and all additional action as is contemplated to be taken by or
on behalf of the Designating Stockholders by the terms of this Agreement,
including without limitation, the execution and delivery of documents to
transfer the Company Shares to Buyer.
 
         (c) Each Designating Stockholder hereby specifically authorizes and
directs the Stockholders' Representative to execute on behalf of such
Designating Stockholder the certificates to be delivered to Buyer by the
Representing Parties and the Stockholders pursuant to Section 6.1 unless such
authorization and direction shall have been revoked by such Designating
Stockholder in writing prior to the Closing.
 
         (d) In the event that the Stockholders' Representative dies, becomes
legally incapacitated or resigns from such position, Robert J. Small shall fill
such vacancy and shall be deemed to be the Stockholders' Representative for all
purposes of this Agreement unless otherwise determined by the Designating
Stockholders owning a majority of the shares of New Stock held (on a fully
diluted basis) by all Designating Stockholders; however, no change in the
Stockholders' Representative shall be effective until Buyer is given notice of
such change by one or more of the Designating Stockholders.
 
         (e) All decisions and actions by the Stockholders' Representative in
accordance with this Agreement shall be binding upon all of the Designating
Stockholders, and no Designating Stockholder shall have the right to object,
dissent, protest or otherwise contest the same.
 
         (f) By their execution of this Agreement, the Designating Stockholders
agree that:
 



                                      4

             (i) Buyer shall be able to rely conclusively on the instructions
        and decisions of the Stockholders' Representative as to any actions
        required or permitted to be taken by the Designating Stockholders or the
        Stockholders' Representative hereunder, and no party hereunder shall
        have any cause of action against Buyer for any action taken by Buyer in
        reliance upon the instructions or decisions of the Stockholders'
        Representative;
 
            (ii) all actions, decisions and instructions of the Stockholders'
        Representative shall be conclusive and binding upon all of the
        Designating Stockholders and no Designating Stockholder shall have any
        cause of action against the Stockholders' Representative for any action
        taken, decision made or instruction given by the Stockholders'
        Representative under this Agreement, except for fraud or willful breach
        of this Agreement by the Stockholders' Representative;
 
           (iii) remedies available at law for any breach of the provisions of
        this Section 1.5 are inadequate; therefore, Buyer shall be entitled to
        temporary and permanent injunctive relief without the necessity of 
        proving damages if Buyer brings an action to enforce the provisions of
        this Section 1.5; and
 
            (iv) the provisions of this Section 1.5 are independent and
        severable, shall constitute an irrevocable power of attorney, coupled
        with an interest and surviving death, granted by the Designating
        Stockholders to the Stockholders' Representative and shall be binding
        upon the executors, heirs, legal representatives and successors of each
        Designating Stockholder.
 
        (g) All fees and expenses incurred by the Stockholders' Representative
shall be paid pro rata by the Designating Stockholders in accordance with their
ownership of New Common Stock.
 
     1.6 Closing. The closing of the purchase and sale of the Company Shares
(the "Closing") shall take place at the offices of Morgan Lewis & Bockius LLP,
101 Park Avenue, New York, New York 10178 on the same day as and promptly after
the Stock Purchase Closing (as defined in the Recapitalization and Stock

Export (consisting of 1,000 shares of common stock), and all such shares are
duly authorized, validly issued, fully paid and non-assessable, and free and
clear of all preemptive rights and all Liens. There are no agreements or
understandings to which the Company or any subsidiary of the Company is a party
with respect to the voting of, or other interest in any shares of Old Stock or
which restrict the transfer of any such shares. There are no outstanding
contractual obligations of the Company or any subsidiary of the Company to
repurchase, redeem or otherwise acquire any shares of capital stock or Option of
the Company or any subsidiary of the Company, or to make any investment in any
subsidiary or any other person. Neither the Company nor any subsidiary of the
Company is under any obligation, contingent or otherwise, by reason of any
agreement to register any of its securities under the Securities Act of 1933, as
amended (the "Securities Act").
 
     2.4 Authority Relative to this Agreement. The Company has all necessary
corporate power and authority to execute and deliver this Agreement and the

The execution and delivery of the Operative Documents by the Company and the
consummation by the Company of the transactions contemplated thereby have been
duly and validly authorized by the Board of Directors of the Company, and no
other corporate proceedings on the part of the Company are necessary to
authorize the Operative Documents, and to consummate the transactions
contemplated thereby. The Operative Documents have been duly and validly
executed and delivered by the Company and, assuming the due authorization,
execution and delivery by the other parties thereto, constitute the valid and
binding agreement of the Company, enforceable against the Company in accordance
with their respective terms.
 
     2.5 Consents and Approvals; No Violations.
 
         (a) The execution and delivery of the Operative Documents by the 
Company does not, and the performance of the transactions contemplated by the 
Operative Documents by the Company will not, except for agreements to be 
terminated at the Closing pursuant to Section 9.6, require any filing with or 
notification to, or any consent, approval, authorization or permit from, any 
governmental or regulatory authority (a "Governmental Entity") or any other 
person except for where failure to obtain such consents, approvals, 
authorizations or permits, or to make such filings or notifications, 
individually or in the aggregate, (X) would not prevent or delay consummation 
of the transactions contemplated by this Agreement, (Y) would not otherwise 
prevent or delay the Company from performing its obligations under this 
Agreement and (Z) would not have a Company Material Adverse Effect.
 


                                      7

   12



        (b) The execution and delivery of the Operative Documents by the Company
does not, and the performance of the transactions contemplated by the Operative
Documents by the Company will not, (i) conflict with or violate the Certificate
of Incorporation or By-Laws (or equivalent documents) of the Company, (ii)

regulation applicable to the Company or any of its subsidiaries, or (iii) result
in a violation or any breach of or constitute a default (or an event which with
notice or lapse of time or both would become a default) under any note, bond,
mortgage, indenture, contract, agreement (except for agreements which will be
terminated at the Closing pursuant to Section 9.6), lease, license, permit,
franchise or other instrument or obligation to which the Company or any of its
subsidiaries is a party or by which any of their respective assets is bound or
(iv) result in the creation or imposition of any Lien upon the Company or any of
its subsidiaries or any of their respective assets, except for any such
conflicts, violations, breaches, defaults or other occurrences which,
individually or in the aggregate, (X) would not prevent or delay consummation of
the transactions contemplated by this Agreement, (Y) would not otherwise prevent
or delay in any material respect the Company from performing its obligations
under this Agreement and (Z) would not have a Company Material Adverse Effect.
 
     2.6 Compliance.
 
        (a) The Company and its subsidiaries have all licenses, permits,
franchises, orders or approvals of any federal, state, local or foreign
governmental or regulatory body or other Governmental Entity material to the
conduct of their businesses on a consolidated basis (collectively, "Company
Permits"), and such Company Permits are in full force and effect and no
proceeding is pending or, to the knowledge of the Company, threatened to revoke
or limit any Company Permit except where the failure to have any such Company
Permit would not have a Company Material Adverse Effect.
 
        (b) Neither the Company nor any of its subsidiaries is in default or
violation of (i) any law, rule, ordinance, regulation, order, judgment or decree
applicable to the Company or any of its subsidiaries or of any Company Permit or
(ii) any note, bond, mortgage, indenture, contract, agreement, lease, license,
permit, franchise or other instrument or obligation to which the Company or any
of its subsidiaries is a party, except for such defaults or violations which,
individually or in the aggregate, would not have a Company Material Adverse
Effect. Since January 1, 1993, neither the Company nor any of its subsidiaries
has received notice of any investigation or review by any Governmental Entity or
any other person concerning any such possible violations by the Company or any
of its subsidiaries, nor has any Governmental Entity or any other person
notified the Company or any of its subsidiaries in writing of its intention to
conduct the same, in each case other than those the outcome of which would not
have a Company Material Adverse Effect.

     2.7 Financial Statements and Undisclosed Liabilities.
 
        (a) The Company has previously delivered to Buyer a true, complete and
correct copy of its audited consolidated financial statements for the years
ended December 31, 1995 and 1994 (the "Audited Financial Statements") and its
unaudited consolidated balance sheet of the Company and its consolidated
subsidiaries as of June 30, 1996 (the "Current Balance Sheet") and the related
statements of operations and accumulated deficit and cash flows for the
six-month period then ended (collectively with the Current Balance Sheet, the
"Current Financial Statements"). The Audited Financial Statements and the
Current Financial Statements were prepared in accordance with generally accepted
accounting principles ("GAAP") applied on a consistent basis throughout the
periods indicated (except as may be otherwise indicated in the notes thereto and
except that the Current Financial Statements do not contain footnotes meeting
the requirements of GAAP) and fairly present the consolidated financial
position, accumulated deficit and results of operations of the Company and its
subsidiaries on a consolidated basis as at the respective dates thereof and for
the respective periods indicated therein (subject, in the case of the Current
Financial Statements, to normal year-end adjustments consistent with past

Company and its subsidiaries do not have any liability or obligation of any

liability or obligation which will not have a Company Material Adverse Effect.
 
     2.8 Absence of Certain Changes. Since June 30, 1996, there has not been
(i) a Company Material Adverse Effect; (ii) any declaration, setting aside or
payment of any dividend or other distribution (whether in cash, stock, or
property or any combination thereof) in respect of any shares of any capital
stock of the Company or any of its subsidiaries, or any direct or indirect
redemption, purchase or other acquisition by the Company or any of its
subsidiaries of any of their respective securities (including any Options),
other than dividends by a subsidiary to the Company; (iii) any entry into any
agreement, commitment or transaction by the Company or any of its subsidiaries
that is material to the Company and its subsidiaries taken as a whole, except
agreements, commitments or transactions in the ordinary course of business; (iv)
any significant change by the Company or any subsidiary in accounting methods,
principles or practices, (v) any acquisition, sale, lease, transfer or
disposition by the Company or its subsidiaries of any material assets or

or any creation or incurrence of a Lien on any such assets or properties, in
each case other than in the ordinary course of business consistent with past
practice; (vi) any authorization, issuance, sale, delivery or other disposition
by the Company or any subsidiary of any shares of capital stock (other than
pursuant to the exercise of any options or conversion rights) of, or any Option
with respect to, the Company or any of its 




                                      9

   14

subsidiaries, or any modification or amendment of any right of any holder 
of any outstanding shares of capital stock of, or any Option with respect
to (except as contemplated by this Agreement), the Company or any of its
subsidiaries; (vii) any damage, destruction or loss (whether or not covered by
insurance) with respect to any property or asset individually or in the
aggregate of the Company or any of its subsidiaries and having a Company
Material Adverse Effect; (viii) except in the ordinary course of business
consistent with past practice or pursuant to working capital credit facilities
in existence on the date of this Agreement, an incurrence of any long-term
indebtedness for borrowed money, a guarantee of any indebtedness, an issuance or
sale of debt securities or warrants or rights to acquire any debt securities, a
guarantee of any debt of others, any loan, advance or capital contribution, any
mortgage, pledge or other encumbrance of any material assets, or the creation of
any material Lien thereupon; (ix) an increase in the compensation payable or to
become payable to the Company's executive officers or employees, except for
increases in the ordinary course of business in accordance with past practice
which do not result in a material increase in benefits or compensation expense
to the Company or its subsidiaries taken as a whole, or the grant of any
severance or termination pay to, any director or executive officer of it or any
of its subsidiaries other than in the ordinary course of business, or the
establishment, adoption, or amendment in any material respect or the
acceleration of any rights or benefits under any collective bargaining, bonus,
profit sharing, thrift, compensation, stock option, restricted stock, pension,
retirement, deferred compensation, employment, termination, severance or other
plan, agreement, trust, fund, policy or arrangement for the benefit of any
director, executive officer or employee except as is provided therein; (x) any
transaction with an affiliate of the Company except in the ordinary course of
business; (xi) any transaction with any Berkshire Stockholder, Prudential, Pruco
or Michigan; or (xii) any agreement (other than this Agreement, the
Recapitalization and Stock Purchase Agreement, and agreements contemplated
hereby or thereby) entered into by the Company to take any of the foregoing
actions.
 
     2.9 Environmental Matters.
 
         (a) The Company and its subsidiaries are in compliance with all
Environmental Laws, except for any noncompliance individually or in the
aggregate that does not have a Company Material Adverse Effect. "Environmental
Laws" shall mean all federal, state and local laws, rules, regulations,
ordinances, common law and orders that purport to regulate the release of
Hazardous Materials (as defined herein) or other materials into the environment,
or impose requirements relating to environmental protection. "Hazardous
Materials" shall mean petroleum and petroleum products, radioactive materials,
pesticides, asbestos and asbestos-containing materials, polychlorinated
biphenyls, and any materials or substances defined as or included in the
definition of "hazardous materials," hazardous wastes," "hazardous substances,"
"toxic substances," "toxic pollutants," "pollutants," "contaminants," "solid
wastes," or "regulated substances" under any applicable Environmental Law. The
Company has previously delivered to Buyer a true and complete copy of
environmental assessment reports prepared by Dames & Moore with respect to
Aetna's facilities (collectively, such reports are referred to as the
"Environmental Reports") 




                                      10

   15

and any other written reports relating to the environmental condition of
any of the Owned Real Estate, Leased Real Estate, or any properties formerly
owned or leased by the Company or its subsidiaries which are in the possession
of the Company, its subsidiaries or its agents.
 
        (b) To the knowledge of the Company, there are no Hazardous Materials
present and there has been no material release or threat of material release of
any Hazardous Material on, in, under, from or to the Owned Real Estate or Leased
Real Estate (as such terms are defined in Section 2.15) or any property formerly
owned or leased by the Company or its Subsidiaries for which the Company or its
subsidiaries could incur material liability, except is indicated by the
information set forth in the Environmental Reports.
 
        (c) No Lien has been imposed on the Owned Real Estate or, to the
Company's knowledge, Leased Real Estate by any governmental agency at the
federal, state, or local level in connection with the presence of any hazardous
material.
 
        (d) None of the Company or either of its subsidiaries has: (i) entered
into or been subject to any consent decree, compliance order, or administrative
order with respect to environmental matters relating to the Owned Real Estate or
Leased Real Estate or any property formerly owned or leased by the Company or
its subsidiaries, the operations of the Company or its subsidiaries, or any
off-site location to which the Company or its subsidiaries sent Hazardous
Materials for treatment, storage, handling or disposal; (ii) received since
January 1, 1995 written notice under the citizen suit provision of any
Environmental Law in connection with the Owned Real Estate or the Leased Real
Estate, any property formerly owned or leased by the Company or its subsidiaries
or the operations of the Company or its subsidiaries; (iii) received since
January 1, 1995 any written request for information, notice, demand letter,
administrative inquiry, or complaint with respect to environmental matters
relating to the Owned Real Estate or the Leased Real Estate, any property
formerly owned or leased by the Company or its subsidiaries, or any off-site
location to which the Company or its subsidiaries sent Hazardous Materials for
treatment, storage, handling or disposal; or (iv) been subject to any
governmental or citizen enforcement action with respect to environmental matters
relating to the Owned Real Estate or the Leased Real Estate, any property
formerly owned or leased by the Company or its subsidiaries, the operations of
the Company or its subsidiaries or any off-site location to which the Company or
its subsidiaries sent Hazardous Materials for treatment, storage, handling or
disposal.
 
     2.10 Litigation. There is no litigation, suit, action, proceeding, or
complaint pending or, to the knowledge of the Company and its subsidiaries,
threatened against the Company or any of its subsidiaries as to which there is a
reasonable likelihood of an adverse determination and which, if adversely
determined, could reasonably be expected to (i) have a Company Material Adverse
Effect, (ii) materially and adversely affect the Company's ability to perform
its obligations under this Agreement or (iii) prevent the consummation of any of
the transactions contemplated by this Agreement. Prior to the date hereof, the
Company has delivered to Buyer all responses of counsel to the Company or its
subsidiaries to auditor's request for information delivered in connection with
the Audited Financial Statements.

     2.11 Employee Benefit Plans.
 
          (a) Disclosure. Section 2.11 of the Disclosure Letter contains a true
and complete list of all pension, benefit, profit sharing, retirement, stock,
deferred compensation, welfare, insurance, disability, severance pay and other
similar plans, programs and agreements, including all "employee benefit plans"
within the meaning of Section 3(3) of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), currently maintained or contributed to by the
Company or its subsidiaries, covering employees of the Company or any entity (a
"Commonly Controlled Entity") that, together with the Company, would be treated
as a single employer under Section 414(b) or (c) of the Internal Revenue Code of
1986, as amended (the "Code") (each an "Employee Plan"). Neither the Company nor
any subsidiary has any current or future obligation under any plan or
arrangement providing health care benefits or other financial benefits to former
employees (other than pension benefits under the defined benefit plans disclosed
in Section 2.11 of the Disclosure Letter and benefits required to be provided
under part 6 of subtitle B of title I of ERISA).
 
          (b) Prohibited Transactions. With respect to each Employee Plan, there
has been no nonexempt "prohibited transaction," as such term is defined in
Section 4975 of the Code or Section 406 of ERISA, in connection with which Buyer
could be subject to a material liability due to either a penalty assessed
pursuant to Section 502(i) of ERISA or a tax imposed by Section 4975 of the
Code.
 
          (c) Compliance. All Employee Plans comply in all material respects 
with, and have been administered in material compliance with, all laws, 
including, but not limited to, ERISA and the Code, applicable to such Employee
Plans. Neither the Company nor Aetna has any liability under Title IV of ERISA,
nor has any event or circumstance occurred which would reasonably be expected 
to result in such a liability being asserted by any party, including the 
Pension Benefit Guaranty Corporation, with respect to any Employee Plan or any
other plan subject to Title IV of ERISA (other than the payment of annual 
premiums). No Employee Plan that is subject to Section 302 of ERISA or Section
412 of the Code, or both, has incurred any "accumulated funding deficiency" 
(as defined in such sections), whether or not waived; nor has the Company or 
any Commonly Controlled Entity failed to pay any amounts due and owing as 
required by the terms of any Employee Plan. If each Employee Plan which is 
subject to Title IV of ERISA were terminated in a "standard termination" (as 
described in Section 4041(b) of ERISA) as of the Effective Time, the current 
value of the assets of such Employee Plan would equal or exceed the "benefit 
liabilities" (as defined in Section 4001(a)(16) of ERISA) of such Employee 
Plan as determined on such date. There has been no partial termination of any 
Employee Plan that would require full vesting under the terms of such Employee
Plan, the Code, ERISA or any other applicable law or ruling.
 
          (d) Multiemployer Plans. Neither the Company nor Aetna has within six
(6) years prior to the Closing been obligated, nor has any other entity within
six (6) years prior to the Closing been obligated at any time when such entity
was a Commonly Controlled Entity, to contribute to any "multiemployer plan" as
such term is defined in Section 4001(a)(3) of


                                      12

   17


ERISA. Neither the Company nor Aetna has any "withdrawal liability," as
computed under Section 4211 of ERISA, with respect to any such plan.
 
        (e) Copies of Employee Plans and Related Documents. Copies of all
Employee Plans which have been reduced to writing, together with copies of
determination letters and annual reports with respect to each qualified Employee
Plan, have been provided to Buyer.
 
        (f) Qualifications. Each Employee Plan which is an "employee pension
benefit plan" (as defined in Section 3(2) of ERISA) intended to qualify under
Section 401(a) of the Code is, and at all times has been, so qualified and has
been determined by the Internal Revenue Service to so qualify, and each trust
created thereunder has been determined to be exempt from tax under the
provisions of Section 501(a) of the Code, and nothing has since occurred which
would cause the loss of such qualification or exemption.
 
        (g) Claims and Litigation. There are no pending claims, suits or other
proceedings in connection with any Employee Plan by present or former employees
of the Company or its subsidiaries, plan participants, beneficiaries or spouses
of any of the above, other than claims by participants or beneficiaries of such
Employee Plan for ordinary and usual benefits to which such beneficiaries or
participants are entitled under the terms of such Employee Plan.
 
     2.12 Trademarks, Patents and Copyrights. The Company and its
subsidiaries own, or possess adequate licenses or other rights to use, all
patents, trademarks, trade names, copyrights, service marks, trade secrets,
know-how and other proprietary rights used in connection with the business of
the Company and its subsidiaries as currently conducted (the "Company
Proprietary Rights") other than any such Company Proprietary Rights which are
not material to the Company and its subsidiaries, and no assertion or claim has
been made in writing since January 1, 1993 challenging the validity of any of
the Company Proprietary Rights. To the knowledge of the Company, the conduct of
the business of the Company and its subsidiaries as currently conducted does not
conflict with any patent, license, trademark, trade name, or copyright of any
other person. Neither the Company nor any subsidiary is in default (or with the
giving of notice or lapse of time or both, would be in default) under any
license to use Company Proprietary Rights, which default individually or in the
aggregate would cause a Company Material Adverse Effect. The Company has
received no written claim or threat that any such conflict exists, and no
litigation, claim, suit, action, proceeding, or complaint concerning the
foregoing has been filed or is ongoing.
 
     2.13 Taxes. The Company and its subsidiaries have duly and timely filed
all Tax Returns required to be filed by them through the date hereof and have
paid all Taxes shown on such Tax Returns or pursuant to any assessments received
by the Company or its subsidiaries, unless contested in good faith in
appropriate proceedings, and all such Tax Returns are correct and complete in
all material respects. All monies (except for amounts that are not material)
required to be withheld by the Company or its subsidiaries from employees,
independent



                                      13
   18


contractors, creditors or other third parties for taxes have been collected 
or withheld, and either duly and timely paid to the appropriate Taxing
Authorities or set aside in accounts for such purposes, except where the failure
to do so will not have a Company Material Adverse Effect. The provisions for
current Taxes made on the Current Financial Statements are sufficient for the
payment of all accrued and unpaid Taxes not yet due and payable as of such date,
except where failure to be so will not have a Company Material Adverse Effect.
Neither the Company nor any of its Subsidiaries is a party to any agreement
extending, or having the effect of extending, the time within which to file any
Tax Return or the period of assessment or collection of any Taxes. Neither the
Internal Revenue Service nor any other Taxing Authority is now asserting or, to
the knowledge of the Company, threatening to assert against the Company or any
of its subsidiaries any material deficiency or material claim for additional
Taxes or interest thereon or penalties in connection therewith. There are no
liens for Taxes upon the assets of the Company and its subsidiaries. Neither the
Company nor any subsidiary (i) is a party to or is bound by any obligations
under any tax sharing, tax indemnity or similar agreement or arrangement, (ii)
has made or is subject to any election under section 341(f) of the Internal
Revenue Code of 1986, as amended, (iii) has made or is subject to any election
or deemed election under section 338 or section 336(a) of the Code or the
regulations thereunder, (iv) has agreed to make any adjustment under section 481
of the Code (or any comparable provision of state, local or foreign law) by
reason of a change in accounting method or otherwise, or (v) has since January
1, 1990 been a member of any affiliated, consolidated, combined, unitary or
similar group for any Tax purpose (other than a group consisting solely of the
Company and its subsidiaries). Aetna Export made a valid election to be
classified as a "small FSC" within the meaning of section 922(b) of the Code for
its taxable year commencing January 1, 1988, and has qualified as a small FSC
for all of its taxable years commencing on or after January 1, 1988, through the
date of the Closing, except where the failure to do so would not be material to
the Company and its subsidiaries on a consolidated basis. "Taxes" means all
federal, state, local or foreign net or gross income, gross receipts, net
proceeds, sales, use, ad valorem, value added, franchise, withholding, payroll,
employment, excise, sales, use, property, alternative or add-on minimum or other
taxes, whether disputed or not, together with any interest, penalties, additions
to tax or additional amounts with respect thereto. "Tax Returns" means any
returns, reports or statements (including any information returns) required to
be filed for purposes of a particular Tax. "Taxing Authority" means any
governmental agency, board, bureau, body, department or authority of any
federal, state, local or foreign jurisdiction, having or purporting to exercise
jurisdiction with respect to any Tax.
 
     2.14 Labor Matters. There is not currently, and within the last three years
neither the Company nor any subsidiary of the Company has experienced, any
strike, lockout, picketing, boycott, work stoppage or slow down or union
organization activity or demands for recognition. The Company has no knowledge
(i) of any allegation, charge or complaint of unfair labor practice, employment
discrimination or other matter relating to the employment of labor pending or
threatened against the Company or any subsidiary of the Company, (ii) of any
basis for any such allegation, charge or complaint or (iii) that it, or any
subsidiary of the Company, has not complied in all material respects or is not
in material compliance with all 

                                      14

   19

applicable laws, rules and regulations relating to the employment of labor 
except where such practice, discrimination matter or non-compliance will not 
have a Company Material Adverse Effect.
 
     2.15 Real Estate.
 
          (a) Owned Real Estate. Section 2.15 of the Disclosure Letter contains 
a true, complete and correct list of all real property owned by the Company or
any of its subsidiaries, directly or indirectly (the "Owned Real Estate").
 
             (i) Title to Owned Real Estate. The Company has made available to
        Buyer true and complete copies of all owner's policies of title
        insurance issued with respect to the Owned Real Estate. To the knowledge
        of the Company, there are no liabilities, liens, encumbrances,
        easements, restrictions, reservations, agreements or other matters
        affecting the Company's title or any subsidiary's title to the Owned
        Real Estate except for those listed in such policies of title insurance
        or otherwise listed in Section 2.15 of the Disclosure Letter (such
        listed matters, the "Permitted Exceptions").
 
             (ii) Condemnation or Eminent Domain Proceedings. There is no
        pending, or to the Company's knowledge, threatened condemnation or
        eminent domain proceedings with respect to any of the Owned Real Estate.
 
             (iii) Taxes. There are no taxes or betterment assessments other
        than ordinary real estate taxes pending or payable against the Owned
        Real Estate. To the Company's knowledge, there are no unpaid taxes or
        levies, permit fees or connection fees remaining unpaid with respect to
        existing curb cuts, sewer hook-ups, water main hook-ups or other

management in the amount of $350,000 (less any applicable withholding taxes) and
payment of deferred compensation to Jerome Singer in the amount of $225,186
(less any applicable withholding taxes), such amounts to be paid at the Closing;
 
        (h) Enter into any transaction with any Berkshire Stockholder,
Prudential, Pruco or Michigan except as discussed in Section 2.22 of the
Disclosure Letter;
 
        (i) Amend or otherwise change the Company's Certificate of Incorporation

        (j) Enter into an agreement to take any of the foregoing actions.
 
     5.3 No Solicitation. Unless this Agreement is terminated in accordance with
its terms, neither the Company nor any of its subsidiaries shall, and the
Company shall use reasonable efforts to ensure that none of its affiliates,
officers, directors, representatives or agents shall, directly or indirectly,
solicit, knowingly encourage or enter into any agreement with respect to or
participate in negotiations with, provide any confidential information to, or
otherwise cooperate in any way in connection with, or enter into any agreement
with respect to, any Third Party (as hereinafter defined) concerning any merger
or any other business combination, sale of a substantial portion of the assets
of the Company and its subsidiaries, or any similar transaction involving the
Company and its subsidiaries (each, a "Business Combination," provided, however,
that no transaction contemplated by this Agreement or the Recapitalization and
Stock Purchase Agreement or involving Buyer or any affiliate thereof shall be a
Business Combination). For purposes of this Agreement, "Third Party" shall mean
any person or persons (other than Buyer, any affiliate of Buyer, or any of
Buyer's directors, 

                                      25

   30

officers, employees, representatives, and agents.) The Company agrees to
terminate, immediately following the execution of this Agreement, any pending
discussions or negotiations with Third Parties with respect to any possible
Business Combination. If, prior to the earlier of the Closing or the termination
of this Agreement, the Company, any subsidiary of the Company or any Stockholder
shall enter into any agreement with a Third Party relating to any Business
Combination, the Company shall reimburse Buyer for all of the fees and expenses
(including fees and expenses of counsel and accountants) incurred by Buyer in
connection with the transactions contemplated by this Agreement.
 
     5.4 Access to Information; Confidentiality.
 
        (a) From the date hereof to the Closing, the Company shall (and shall
cause its subsidiaries and officers, directors, employees, auditors and agents
to) afford the officers, employees and agents of Buyer (the "Representatives")
reasonable access at mutually convenient times to its officers, employees,
agents, properties, offices, plants and other facilities, books and records, and
shall furnish such Representatives with all financial, operating and other data
and information as may be reasonably requested by Buyer.
 
        (b) All information obtained by Buyer pursuant to this Section 5.4
shall, to the extent required thereby, be kept confidential in accordance with
the terms of the Confidentiality Agreement dated January 13, 1995 between Aetna
and Citicorp Venture Capital Ltd. (the "Confidentiality Agreement").
 
     5.5 Public Announcements. Buyer and the Company shall consult with each
other before issuing any press release or otherwise making any public statements
with respect to this Agreement or any transaction contemplated herein and shall
not issue any such press release or make any such public statement without the
prior consent of the other party, which consent shall not be unreasonably
withheld; provided, however, that a party may, without the prior consent of the
other party, issue such press release or make such public statement as may be
required by law if it has used all reasonable efforts to consult with the other
party and to obtain such party's consent but has been unable to do so in a
timely manner.
 
     5.6 Agreement Not To Merge. Buyer agrees that it will not, until the second
anniversary of this Agreement, merge with and into the Company or agree to do
so; provided, however, that Buyer may so merge with the Company on any date
following the first anniversary of the date of this Agreement if, prior to the
date of such merger, there has been a Qualifying Offering of the Company's
common stock.
 
     5.7 Agreement To Issue Shares. Buyer agrees that, immediately prior to the
Closing, it shall issue shares of its common stock to the Company, such shares
to be all of the issued and outstanding capital stock of Buyer, and the Company
agrees that, in return for the issuance of such shares, it will (i) make a
capital contribution to Buyer of all the issued and outstanding shares of
capital stock of Aetna and (ii) simultaneously with the Closing, issue, on
behalf of Buyer, the Deferred Obligations.

SECTION 7. INDEMNIFICATION.
 
     7.1 Indemnification by the Stockholders and Management Holders. Each
Stockholder and Management Holder individually with respect to the
representations and warranties made by such Stockholder and Management Holder in
Section 3 and each Stockholder and Management Holder jointly and severally with
respect to the representations and warranties in Section 2, agrees to indemnify
and hold Buyer subject to the provisions of this Section 7, harmless from and
against any damages, liabilities, losses, fines, penalties, costs, and expenses
(including, without limitation, reasonable fees of counsel) of any kind or
nature whatsoever (collectively, "Losses") which may be sustained or suffered by
Buyer arising out of or based upon any breach of any representation or warranty
contained in Section 2 or 3 of this Agreement or of such Stockholder and
Management Holder under or in any certificate delivered by such Stockholder and
Management Holder pursuant hereto or based upon any breach of any covenant or
agreement, required by this Agreement to be performed before the Closing, by
such Stockholder.
 
     7.2 Limitations on Indemnification by the Stockholders and Management
Holders.
 
        (a) Notwithstanding the foregoing and subject to Section 7.6(d), (i)
except for any claim arising out of or based upon a breach of Sections 2.9, 2.11
or 2.13 of this Agreement, no indemnification shall be payable to Buyer with
respect to claims asserted pursuant to Section 7.1 on any date after the first
anniversary of the Closing, (ii) with respect to any claim arising out of or
based upon a breach of Section 2.9 or 2.11 of this Agreement, no indemnification
shall be payable to Buyer with respect to claims asserted pursuant to Section
7.1 on any date after the third anniversary of the Closing, (iii) with respect
to any claim arising out of or based upon a breach of Section 2.13 of this
Agreement, no indemnification shall be payable to Buyer with respect to claims
asserted pursuant to Section 7.1 on any date after the expiration of the statute
of limitations applicable to such claim (each such date being an
"Indemnification Cut-Off Date"), (iv) no Stockholder or Management Holder shall
be liable unless, and only to the extent that, the Losses for which the Buyer is
entitled to be indemnified for hereunder exceed, individually or in the
aggregate, $500,000 (any such excess, the "Indemnifiable Losses") and (v) each
Stockholder's and Management Holder's liabilities under this Section 7 with
respect to the Indemnifiable Losses shall be further limited by and paid only
according to the provisions of Section 7.6(b) and (c).
 
        (b) No Stockholder or Management Holder shall be liable under this
Section 7 for an aggregate amount, for all claims made pursuant to this Section
7, in excess of the Set-Off Percentage (as defined in Section 7.6(a)) applicable
to each Note or Deferred Obligation held by such Stockholder or Management
Holder immediately following the Closing multiplied by five million dollars
($5,000,000).
 
        (c) Notwithstanding any other provision of this Agreement, no
Stockholder or Management Holder shall be liable hereunder with respect to any
individual claim for indemnification for an Indemnifiable Loss unless such
Indemnifiable Loss is greater than 



                                      29
   34

$15,000, and thereafter the entire amount of such Indemnifiable Loss shall be 
recoverable, to the extent provided by and in accordance with the provisions 
of, this Section 7.
 
     7.3 Indemnification by Buyer. Buyer agrees to indemnify and hold each of
the Stockholders and Management Holders harmless from and against any Losses
which may be sustained or suffered by any of them arising out of or based upon
any breach of any representation, warranty or covenant made by Buyer in this
Agreement or in any certificate delivered by Buyer pursuant hereto.
 
     7.4 Limitation on Indemnification by Buyer. Notwithstanding the foregoing,
no indemnification shall be payable to the Stockholders with respect to claims
asserted pursuant to Section 7.3 above after the fourth anniversary of the
Closing.
 
     7.5 Notice; Defense of Claims. An indemnified party may make claims for
indemnification hereunder by giving written notice thereof to any indemnifying
party within the period in which indemnification claims can be made hereunder;
provided, however, that notice by Buyer to the Designating Stockholders will be
deemed to be given if notice is given by Buyer to the Stockholders'
Representative. If indemnification is sought for a claim or liability asserted
by a third party, the indemnified party shall also give written notice thereof
to the indemnifying party promptly after it receives notice of the claim or
liability being asserted, but the failure to do so shall not relieve the
indemnifying party from any liability except to the extent that it is materially
prejudiced by the failure or delay in giving such notice. Such notice shall
summarize the bases for the claim for indemnification and any claim or liability
being asserted by a third party. The indemnifying party shall be entitled to
direct the defense against a third party claim or liability if it so elects. The
indemnified party shall at all times have the right to fully participate in the
defense of a third party claim or liability at its own expense directly or
through counsel. If the indemnifying party decides not to direct the defense,
the indemnified party shall have the right, at the expense of the indemnifying
party, to undertake the defense of such claim or liability (with counsel
selected by the indemnified party), and to compromise or settle it, exercising
reasonable business judgment. If the third party claim or liability is one that
by its nature cannot be defended solely by the indemnifying party, then the
indemnified party shall make available such information and assistance as the
indemnifying party may reasonably request and shall cooperate with the
indemnifying party in such defense. If the parties hereto attempt to resolve in
good faith a claim for indemnification hereunder and if such claim is not
resolved within 60 days from the date of such claim, the party making such claim
may bring suit in a court of competent jurisdiction.
 
     7.6 Satisfaction of Stockholder Indemnification Obligations.
 
        (a) Upon providing notice to the Stockholders and Management Holders of
a claim for an Indemnifiable Loss (the "Claimed Amount") pursuant to this
Section 7 within the applicable time periods set forth in Section 7.2(a), Buyer
shall be entitled to withhold payment of a portion of the unpaid principal
amount of each Note and Deferred Obligation that is still outstanding, such
withheld amount to be equal to the Claimed Amount multiplied by a fraction 



                                      30

   35

(such fraction herein referred to, for each such Note and Deferred Obligation,
as the "Set-Off Percentage"), the numerator of which shall be the principal
amount of each such Note or Deferred Obligation (or such Secondary Note (as such
term is defined in the Notes) or such correspondeing obligation under a Deferred
Obligation) then outstanding, as the case may be, and the denominator of which
shall be a notional amount equal to the sum of (i) the aggregate principal
amount of all then outstanding Notes and Deferred Obligations, (ii) the
aggregate principal amount of Notes and Deferred Obligations which have been
acquired or satisfied by the Company or any affiliate thereof in transactions
which did not constitute pro rata prepayments in accordance with the terms
thereof, (iii) the aggregate principal amount of all Secondary Notes and the
corresponding obligations under the Deferred Obligations which would have been
issued in connection with such acquired Notes or Deferred Obligations (both
directly with respect to such Notes or Deferred Obligations and indirectly with
respect to Notes or Deferred Obligations derivative therefrom) if they had not
been acquired, (iv) the aggregate principal amount of all Notes and Deferred
Obligations converted pursuant to their terms and conditions and (v) the
aggregate principal amount of all Secondary Notes and the corresponding
obligations under the Deferred Obligations which would have been issued in
connection with such converted Notes or Deferred Obligations (either directly
with respect to such Notes or Deferred Obligations or indirectly with respect to
Notes or Deferred Obligations derivative therefrom) if they had not been
converted. Upon a Determination (as defined in paragraph (b)) and the set-off or
reduction by the buyer as provided below, payment of such withheld amounts shall
be made as provided by the terms of the Notes and Deferred Obligations.
 
        (b) Notwithstanding the provisions of paragraph (a) above, Buyer shall
be entitled to indemnification with respect to the amount of or any portion of
the amount of a claim pursuant to Section 7.1 hereof only upon the earlier of
(i) the execution and delivery by Buyer, the Stockholders and Management Holders
of a joint written statement acknowledging the liability for any such amount or
(ii) the final adjudication after all appeals by a court of competent
jurisdiction that Buyer is entitled to indemnification with respect to such
Claimed Amount or for an amount determined pursuant to the provisions of this
Section 7 which such court shall deem proper (each such acknowledgment or
determination, a "Determination" and the amount of the claim so acknowledged or
determined an "Indemnifiable Claim").
 
        (c) Any and all amounts owed to Buyer by any Stockholder or Management
Holder with respect to an Indemnifiable Claim shall be satisfied only by means
of a reduction, by the appropriate Set-Off Percentage, in the principal amount
still outstanding of and accrued but unpaid interest on each Note and Deferred
Obligation held by such Stockholder or Management Holder; provided, however,
that (i) if an Indemnifiable Claim is asserted prior to June 30, 1997, reduction
shall be made first to the Prepayment Principal Amount (as such term is defined
in the Notes) and (ii) if an Indemnifiable Claim is asserted on or after June
30, 1997, such reduction shall be made only to the Remaining Principal Amount
(as such term is defined in the Notes); provided further, if the Indemnifiable
Claim relates to a breach of a representation or warranty in Section 3, the
Indemnifiable Claim may be satisfied (subject to all limitations set forth in
this Section 7) only by means of a reduction in the principal amount 




                                      31

   36


of and accrued but unpaid interest on the Notes and the Deferred Obligations, 
if any, issued on the date of this Agreement to the Stockholder or Management 
Holder who made such representation or warranty and to whom such 
representation or warranty relates and no other Stockholder or Management Holder
shall be liable for any portion of such Indemnifiable Claim and no other Notes
or Deferred Obligations shall be subject to reduction in principal amount or
accrued interest pursuant to this Section 7. It is agreed and understood that
any reduction to the amounts, if any, due under the Notes or Deferred
Obligations pursuant to this Section 7 shall be in complete satisfaction of any
and all amounts payable to Buyer by such Stockholder or Management Holder with
respect to any Indemnifiable Claim made pursuant to this Section 7, and in no
event shall the aggregate amount payable pursuant to this paragraph (c) by any
Stockholder or Management Holder with respect to all Indemnifiable Claims exceed
the amount set forth in Section 7.2(b).
 
        (d) If any of the Notes or Deferred Obligations are converted, pursuant
to their terms and provisions, into shares of common stock of the Company or are
paid or payable by the Company, Buyer shall have no right to make any further
claims for indemnification pursuant to this Section 7; provided, however, if,
prior to such conversion or prepayment in the case of a prepayment at the option
of Buyer, Buyer has made a claim for indemnification pursuant to this Section 7,
then until the date on which a Determination related to such claim is made, each
Stockholder or Management Holder (or, if the claim relates to a breach of a
representation or warranty contained in Section 3, the Stockholder or Management
Holder who made such representation or warranty and to whom such representation
or warranties relates) shall retain the lesser of (i) all shares of common stock
received by such Stockholder or Management Holder upon such conversion or (ii) a
number of shares of common stock received by such Stockholder or Management
Holder upon such conversion, valued at the closing price of such stock on the
date of the conversion therefor of the underlying Notes or Deferred Obligations,
equal in value to the Set-Off Percentage applicable to the Note or Deferred
Obligation so converted multiplied by the lesser of (X) the amount of such
Indemnifiable Claim or (Y) the "Aggregate Limit Amount," which shall mean the
least of (A) $5,000,000, (B) the amount of such claim or (C) $5,000,000 less the
sum of all Indemnifiable Claims previously satisfied by the Stockholders and
Management Holders and of any other amounts being retained by such Stockholder
or Management Holder pursuant to this sentence. If such retained shares are
subsequently sold or if the Note or Deferred Obligation is prepaid at the option
of Buyer, each Stockholder or Management Holder shall retain an amount in cash
equal to the lesser of (i) the net proceeds (after expenses and taxes) of such
sale or such prepayment amount, as applicable or (ii) the Set-Off Percentage
applicable to the Note or Deferred Obligation converted or prepaid at the option
of Buyer by such Stockholder or Management Holder multiplied by the lesser of
(X) the amount of such Indemnifiable Claim or (Y) the Aggregate Limit Amount.
After a Determination has been made with respect to such claim and the amount of
the Indemnifiable Claim has been determined, Buyer's sole remedy pursuant to
this paragraph (d) with respect to each Stockholder or Management Holder shall
be, at the election of each Stockholder and Management Holder, to receive from
each Stockholder and Management Holder either (i) cash in an amount equal to the
Set-Off Percentage applicable to the Note or Deferred Obligation converted or
prepaid at the option of 



                                      32

   37



Buyer by such Stockholder or Management Holder multiplied by the lesser of 
(x) the amount of such Indemnifiable Claim or (y) the Aggregate Limit Amount
or (ii) a number of shares of common stock of the Company, valued at the closing
price of such stock on the date of the conversion therefor of the underlying
Notes or Deferred Obligations, equal in value to the Set-Off Percentage
applicable to the Note or Deferred Obligation converted by such Stockholder or
Management Holder multiplied by the lesser of (X) the amount of such
Indemnifiable Claim or (Y) the Aggregate Limit Amount. In the event of a
conversion or prepayment at the option of Buyer, the aggregate amount payable by
any Stockholder or Management Holder pursuant to this paragraph (d) shall not
exceed the amount of the least of (i) the amount set forth in Section 7.2(b),
(ii) the value of the shares of common stock of the Company received by such
Stockholder or Management Holder upon conversion or prepayment at the option of
Buyer of the Notes or Deferred Obligations, valued at the closing price of such
stock on the date of such conversion or prepayment or (iii) the net cash
proceeds (after expenses and taxes) of the sale of the common stock received by
such Stockholder or Management Holder upon conversion or from prepayment at the
option of Buyer of the Notes or Deferred Obligations, as the case may be.

assign its rights under Section 7, subject to the provisions thereof, to any
holder of Senior Debt (as such term is defined in the Notes) on the day of the

reason of this Agreement, except pursuant to Sections 5.1 and 9.11 hereof.

therein or necessary to make the statements in any of them not misleading and
will promptly reimburse each such person for any reasonable legal and other
expenses as such expenses are incurred by such person in connection with

reliance upon or in conformity with written information furnished specifically
for use therein to the Company or its representative by or on behalf of such
person.

be performed at or prior to the Closing.
