     equal to $340,000,000.00  plus 40% of the Adjustment Amount (whether
     positive or negative), (b) an instrument of assumption reasonably
     satisfactory to each Seller and Buyer assuming, subject to the other terms
     and conditions of this Agreement, all of the obligations and liabilities of

     documents as are specifically required by this Agreement, (D) certified

     authorizing the execution, delivery and performance of this Agreement and
     the Ancillary Agreements to which Buyer is a party, (E) a certificate of

     opinion of Buyer's special counsel, addressed to each Seller and dated the

          (ii) At the Closing, subject to and on the terms and conditions set
     forth in this Agreement, Sellers shall deliver or cause to be delivered to
     Buyer (A) such appropriately executed instruments of sale, assignment,
     transfer and conveyance in form and substance reasonably satisfactory to
     Buyer and Seller and its counsel evidencing and effecting the sale and
     transfer to Buyer of the Interests (it being understood that such
     instruments shall not require Sellers or their Affiliates to make any
     additional representations, warranties or covenants, expressed or implied,
     not contained in this Agreement), (b) such other documents as are
     specifically required by this Agreement, (C) certified copies of
     resolutions duly adopted by the board of directors of each Seller
     authorizing the execution, delivery and performance of this Agreement and
     the Ancillary Agreements, to the extent each is a party hereto or thereto,
     (D) a certificate of the Secretary or an Assistant Secretary of each

     Seller's special counsel, addressed to Buyer and dated the Closing Date,
     substantially in the form attached hereto as EXHIBIT 2(a)(ii).

          (b)  NET WORTH ADJUSTMENT.

          (i) Within 60 days after the Closing Date, UDLP shall, with the
     assistance of FMC consistent with past practice, prepare and deliver to
     Buyer a balance sheet of UDLP as of the Closing Date (the "CLOSING BALANCE
     SHEET").  The Closing Balance Sheet shall be prepared in a manner
     consistent with the June 30 Balance Sheet and in accordance with the
     Applicable Accounting Principles (without regard to any purchase accounting
     adjustments arising out of the consummation of the transactions
     contemplated hereby).  The Closing Balance Sheet shall be audited by Ernst
     & Young L.L.P. ("E&Y"). E&Y shall also provide audited financial statements
     through the Closing Date to Sellers so that each may comply with its
     respective reporting obligations.  In connection with the foregoing, UDLP
     shall provide the Closing Date financial reporting system ("FRS")  package
     to FMC five days prior to the commencement of the E&Y audit, and UDLP shall
     provide Buyer and Sellers a complete list of all adjustments to accruals in
     excess of $250,000 made subsequent to June 30, 1997.  E&Y may begin field
     work for procedural tests prior to delivery of the Closing Date FRS
     package.

          Within 60 days after the Closing Date, UDLP shall, with the assistance
     of FMC, prepare and deliver to Buyer a statement of the Adjusted Net Worth
     Amount as of the Closing Date (the "CLOSING STATEMENT").  The Closing
     Statement shall be prepared based solely upon the Closing Balance Sheet,
     adjusted in accordance with the principles set forth on SCHEDULE 2(b)
     hereto (the "ADJUSTMENT PRINCIPLES") which, in the event of a conflict with
     the Applicable Accounting Principles, shall control.  The parties agree
     that the determination


                                       -5-

<PAGE>

     contemplated by this Section 2(b) is solely intended to show changes
     between the Adjusted Net Worth Amount on the Closing Date and the Target
     Adjusted Net Worth Amount as calculated in accordance with Schedule 2(b).
     Subject to the Adjustment Principles, the Target Adjusted Net Worth Amount
     is based upon methodologies, practices and principles used in connection
     with the preparation of the June 30 Balance Sheet and the adjustment
     contemplated by this Section 2(b) can only be properly measured if the
     Closing Statement is prepared using such methodologies, practices and
     principles.  During the preparation of the Closing Statement and the period
     of any dispute with respect thereto, Buyer shall and shall cause UDLP to
     (A) provide FMC and FMC's representatives with full access during normal
     business hours to the books, records (including work papers, schedules,
     memoranda and other documents), facilities and employees of UDLP, (b)
     provide FMC as promptly as practicable following the Closing Date (but in
     no event later than 30 days after the Closing Date) with normal year-end
     closing financial information for UDLP for the period ending as of the
     opening of business on the Closing Date and (C) cooperate fully with FMC
     and FMC's representatives, including the provision on a timely basis of
     full access to employees and all other information necessary or useful in
     connection with the preparation of the Closing Statement.  The Closing
     Statement shall be reviewed by E&Y and accompanied by an appropriate report
     confirming that the Closing Statement has been prepared in accordance with
     this Section 2(b).  During the 30 days immediately following receipt by
     Buyer and FMC of the Closing Statement, Buyer and FMC shall be permitted to
     review E&Y's working papers relating to the audit of the Closing Balance
     Sheet and review of the Closing Statement and Buyer shall be permitted to
     review the financial and accounting papers provided by FMC for use in
     preparing the Closing Statement.

          The Closing Statement shall become final and binding upon the parties
     hereto on the thirtieth day following receipt thereof by Buyer and FMC
     unless Buyer or FMC gives written notice of its disagreement (a "NOTICE OF
     DISAGREEMENT") to UDLP and the other parties hereto  prior to such date.
     Any Notice of Disagreement shall (A) specify in reasonable detail the
     nature and amount of any disagreement so asserted and (b) only include
     disagreements based on mathematical errors or based on the Closing
     Statement not being prepared in accordance with this Section 2(b).  If a
     timely Notice of Disagreement is delivered, then the Closing Statement (as
     revised in accordance with clause (x) or (y) below) shall become final and
     binding upon the parties on the earlier of (x) the date the parties hereto
     resolve in writing any differences they have with respect to any matter
     specified in the Notice of Disagreement or (y) the date any matters
     properly in dispute are finally resolved in writing by the Accounting Firm.
     During the 30 days immediately following the delivery of a Notice of
     Disagreement, FMC and Buyer shall seek in good faith to resolve in writing
     any differences which they may have with respect to any matter specified in
     the Notice of Disagreement.  During such period, Buyer or FMC, as
     applicable, shall have full access to the working papers of the other
     prepared in connection with Buyer's review of the Closing Statement and
     preparation of  such other party's Notice of Disagreement.  At the end of
     such 30-day period, FMC and Buyer shall submit to a "Big-Six" accounting
     firm (the "ACCOUNTING FIRM") for review and resolution of any and all
     matters which remain in dispute and which were properly included


                                       -6-

<PAGE>

     in the Notice of Disagreement, and the Accounting Firm shall make a final
     determination of the Closing Statement which shall be binding on the
     parties (it being understood, however, that the Accounting Firm shall act
     as an arbitrator to determine, based solely on presentations by Buyer and
     FMC (and not by independent review), only those matters which remain in
     dispute and which were properly included in the Notice of Disagreement).
     The Closing Statement shall become final and binding on Buyer and Sellers
     on the date the Accounting Firm delivers its final resolution to the
     parties (which final resolution shall be delivered as soon as practicable
     following the selection of the Accounting Firm and in any event within 30
     days thereafter).  The Accounting Firm shall be selected by FMC and Buyer
     or, if such parties are unable to agree, by FMC's and Buyer's independent
     accountants.  The fees and expenses of E&Y and the Accounting Firm pursuant
     to this Section 2(b) shall be borne 50% by Buyer and 50% by Sellers on a
     Pro Rata Basis.

          (ii) If the Estimated Final Purchase Price is less than the Final
     Purchase Price, Buyer shall, and if the Estimated Final Price is greater
     than the Final Purchase Price, Sellers shall, within five business days
     after the Closing Statement becomes final and binding on the parties, make
     payment to the other party or parties by wire transfer in immediately
     available funds of the amount of such difference, together with interest
     thereon at the average one-month London Interbank Offered Rate as quoted by
     the Bloomberg Financial Markets Commodities and News Service calculated on
     the basis of the number of days elapsed from the Closing Date to the date
     of payment.  Any payments to or by Sellers pursuant to this clause (ii)
     shall be made on a Pro Rata Basis to or by, as the case may be, FMC and
     Harsco.

          (iii) For purposes of this Agreement, the term "ADJUSTED NET WORTH
     AMOUNT" means the total assets of UDLP and its consolidated Subsidiaries as
     of the Closing Date, LESS the total liabilities of UDLP and its
     consolidated Subsidiaries as of the Closing Date, as reflected on the
     Closing Balance Sheet, after giving effect to the Adjustment Principles
     described on SCHEDULE 2(b).

          (iv) Each party agrees that it will not take any actions with respect
     to the accounting books, records, policies and procedures of UDLP that
     would obstruct or hinder the preparation of the Closing Statement as
     provided in this Section 2(b).  Buyer will cooperate in the preparation of
     the Closing Statement, including providing customary certifications to
     Sellers or, if requested, to Sellers' auditors, Ernst & Young L.L.P. or the
     Accounting Firm.  Harsco acknowledges and agrees that FMC has sole
     authority to act on behalf of Sellers with respect to all matters relating
     to this Section 2(b).

          (c)  LIMITED PARTNERSHIP FORM OF UDLP.  Buyer hereby agrees that it
will take all necessary action, including assigning portions of its rights to
purchase the Interests to one or more of its Affiliates, in order to maintain
UDLP as a validly existing Delaware limited partnership for a period of at least
thirty (30) days following the Closing Date, and for at least such 30-day period
Buyer shall take no actions which would have the effect of dissolving, winding
up or liquidating UDLP under the Code or the Delaware Revised Uniform Limited
Partnership Act, each as in effect


                                       -7-

<PAGE>


at such time.  Notwithstanding any provision of this Agreement to the contrary,
no representation, warranty or covenant shall be deemed to be breached and no
condition to Closing shall be deemed to be unsatisfied as a result of any actual
or prospective impediment to any dissolution, liquidation or winding up of UDLP,
it being understood that Sellers have made and are making no representations or
warranties concerning Buyer's ability to liquidate or otherwise restructure
UDLP.

          (d)  TRANSFER TO FMC AFFILIATE.  Notwithstanding anything to the
contrary in this Agreement, the parties hereto agree that, prior to the Closing,
FMC may transfer all of the Interests owned by it to an Affiliate of FMC that is
(i) incorporated in a domestic jurisdiction and (ii) 100% directly or indirectly
owned by FMC, provided that such transfer does not adversely affect UDLP or
Buyer and provided that such Affiliate agrees to be bound by the terms hereof.
Upon such a transfer, the defined term "FMC" as used herein or in the Ancillary
Agreements shall be deemed to include such Affiliate.  In no event shall FMC be
relieved of any obligation for which it would otherwise be liable hereunder in
the absence of such a transfer.

          3.   CONDITIONS TO CLOSING.

          (a)  BUYER'S OBLIGATION.  The obligation of Buyer to purchase and pay

     Agreement shall be true and correct in all material respects as of the date

     performed or complied with all obligations and covenants required by this
     Agreement to be performed or complied with by such Seller by the time of
     the Closing, except for breaches of such representations and warranties and
     covenants that, in the aggregate, together with all information disclosed
     in any supplements, modifications and updates to the Schedules by Sellers
     prior to the Closing as permitted by this Agreement, would not have a
     Material Adverse Effect; and each Seller shall have delivered to Buyer a
     certificate dated the Closing Date and signed by a Vice President of it
     confirming the foregoing;

     been no change in the Business, or the assets, liabilities or financial
     condition of UDLP, its Subsidiaries and Foreign Affiliates, taken as a
     whole, which would result in a Material Adverse Effect (it being understood
     that the failure to be awarded, or the failure to receive government
     funding for, any contract currently under proposal before or after the date
     hereof does not and shall not constitute a failure of the condition set
     forth in this Section 3(a)(v));

          (vi) All Financing Obligations (other than the Continuing LC
     Obligations) shall have been finally repaid in full, terminated or
     reflected in the computation of the Adjusted Net Worth Amount on the

     Closing Date, except to the extent of changes or developments contemplated
     by the terms of this Agreement and except for representations and
     warranties that speak as of a specific date or time (which need only be
     true and correct as of such date or time), and Buyer shall have performed
     or complied with all obligations and covenants required by this Agreement
     to be performed or complied with by Buyer by the time of the Closing,
     except for breaches of such representations and warranties and covenants

     Ancillary Agreements and the other agreements contemplated hereby and
     thereby at and after the Closing; and Buyer shall have delivered to each
     Seller a certificate dated the Closing Date and signed by a Vice President

     Agreements to which it is a party; and

operation of the Business, taken as a whole, are in normal operating condition
and repair (subject to normal wear and tear).  This Section 4C(e) does not

"PROPERTY" and collectively as the "PROPERTIES".  UDLP or a Subsidiary has fee
simple title to the Owned Properties, and has a valid leasehold interest in each
of the Leased Properties, in each case free and clear of all mortgages, liens,
security interests, easements, covenants, rights-of-way and other similar
restrictions of any nature whatsoever, except (i) Permitted Liens (as defined in
Section 4C(e) above), (ii) easements, covenants, conditions, rights-of-way and
other restrictions of record that are disclosed in any commitment for title
insurance or other title report previously delivered or made available to Buyer,

restrictions which do not materially and adversely affect the use as currently
conducted of the Owned Properties, (vi) acts done or suffered to be done by, and
judgments against, Buyer and those claiming by, through or under Buyer,
(vii) any and all orders, decrees, awards or judgments related to any eminent
domain or condemnation proceedings which do not materially and adversely affect
the use as currently conducted of the Owned Properties, (viii) other liens,
security interests, easements, covenants and restrictions of any nature
whatsoever which individually or in the aggregate do not materially and
adversely affect the value or use as currently conducted of the Owned Properties
and (ix) with respect to the lease for the property in Aiken, South Carolina
listed on SCHEDULE 4C(f)-2, an "industrial revenue bond", a copy of which has
been made available to Buyer.  Except as set forth on Schedule 4C(f)-1, (i) all
improvements located on the Property are, in the aggregate, in normal operating
condition and repair (normal wear and tear excepted) and, to the knowledge of
Sellers, are free from material structural defect and (ii) there is not now
pending any condemnation or eminent domain proceeding affecting the Property or
any portion thereof, nor, to the knowledge of Sellers, is any such proceeding
threatened by any governmental authority.

          (g)  INTELLECTUAL PROPERTY.  The Intellectual Property of UDLP that is
described in clauses (i), (ii) and (iii) of Section 1(a)(vii) is listed on
SCHEDULE 4C(g).   Except as disclosed on SCHEDULE 4C(g) or the other Schedules
hereto, UDLP or a Subsidiary or Foreign Affiliate owns or has the right to use,
without payment to any other party, all material Intellectual Property used in
its business.  Except as set forth on SCHEDULE 4C(g) or the other Schedules
hereto, no material claims are pending in writing or, to the knowledge of
Sellers, threatened in writing against UDLP or a Subsidiary or Foreign Affiliate
as of the date of this Agreement by any person with respect to the ownership or
use of any of the Intellectual Property owned by UDLP and used in the Business.
Except as set forth on SCHEDULE 4C(g) or the other Schedules hereto, no material
licenses, sublicenses or agreements pertaining to any of the Intellectual
Property owned by UDLP and used in the Business have been granted or entered
into by UDLP or a Subsidiary or Foreign Affiliate.  None of  Sellers and UDLP
has received any notices of any infringement by any third party with respect to
any of the Intellectual Property owned by UDLP and used in the Business.  Except
as set forth on SCHEDULE 4C(g) or the other Schedules hereto, to the knowledge
of Sellers, the operation of the Business does not infringe upon any proprietary
right or other Intellectual Property right of any person in any material
respect.  All rights pertaining to Intellectual Property licensed to UDLP by FMC
pursuant to the FMC Intellectual Property Agreement are duly and validly held by
FMC, free and clear of all material Liens.  All rights pertaining to
Intellectual Property to be licensed to UDLP by Harsco pursuant to the Harsco

giving of notice, or both) in material breach or material default thereunder
and, to the knowledge of Sellers, no other party thereto is (with or without
lapse of time or the giving of notice, or both) in material default under any
Material Contract.  Except as set forth on SCHEDULE 4C(h), all of the Material
Contracts are (i) in full force and effect and (ii) to the knowledge of Sellers,
represent the legal, valid and binding obligations of the other parties thereto
and are enforceable against such parties in accordance with their terms.

         (iv)    All contributions and payments with respect to each UDLP
    Employee Benefit Plan have been timely made when due and there are no
    funding deficiencies (including accumulated funding deficiencies) (as

         (v)     All ERISA reporting and disclosure obligations have been
    satisfied in all material respects with respect to each UDLP Employee
    Benefit Plan.

    plan.

    Benefit Plan that is an "employee pension benefit plan" as defined in
    Section 3(2) of ERISA (each, a "PENSION PLAN") which is subject to the
    minimum funding requirements of ERISA is acceptable under law, and the
    actuarial assumptions used in connection with funding each such plan are
    reasonable.  As of the Closing Date, the "amount of unfunded benefit
    liabilities" as defined in Section 4001(a)(18) of ERISA of each Pension
    Plan (but excluding from the definition of "current value" of "assets" of
    such Pension Plan accrued but unpaid contributions) did not exceed zero.

         (xi)    UDLP and its Subsidiaries have not engaged in, nor are
    successors or parent corporations to an entity that has engaged in, a
    transaction described in Section 4069 of ERISA.  There has been no
    "reportable event" (as defined in Section 4043(b) of ERISA and

    and no analogous event under applicable foreign law.  No filing has been
    made by UDLP or either Seller with the PBGC, and no proceeding has been
    commenced by the PBGC, to terminate any Pension Plan.  No condition exists
    and no event has occurred that could constitute grounds for the termination
    of any Pension Plan by the PBGC.  UDLP  has not at any time, (1) ceased
    operations at a facility so as to become subject to the provisions of
    Section 4062(e) of ERISA or analogous foreign law, (2) withdrawn as a
    substantial employer so as to become subject to the provisions of Section

    4064(a) of ERISA or analogous foreign law to which UDLP made contributions
    during the six years prior to the Closing Date.

         (xii)   There is no contract, agreement, plan or arrangement covering
    any employee or former employee of UDLP that, individually or collectively,
    provides for the payment prior to or in connection with this transaction by
    UDLP of any amount (i) that is not deductible under Section 162(a)(1) or
    404 of the Code or (ii) that is an "excess parachute payment" pursuant to
    Section 280G of the Code.

         (xiii)  Each material trust agreement, annuity contract or other

    under any UDLP Employee Benefit Plan that is pending or, to the knowledge
    of Sellers, threatened against UDLP or any UDLP Employee Benefit Plan.

         (xv)    Neither UDLP nor Sellers has any legally binding commitment to
    create any additional employee benefit plans which are intended to cover
    UDLP employees or to amend or modify any existing UDLP Employee Benefit
    Plan which would result in a material increase in the costs to UDLP of such
    Plan.

         (xvi)   No UDLP Employee Benefit Plan holds as an asset any interest
    in any annuity contract, guaranteed investment contract or any other
    investment or insurance contract issued by an insurance company that, to
    the knowledge of Sellers, or UDLP is the subject of bankruptcy,
    conservatorship or rehabilitation proceedings.

         (xvii)  Neither the execution and delivery of this Agreement by
    Sellers nor the consummation of the transactions contemplated hereby or the
    related transactions will result in the acceleration or creation of any
    rights of any person to benefits under any UDLP Employee Benefit Plan
    (including, without limitation, the acceleration of the vesting or
    exercisability of any stock options, the acceleration of the vesting of any
    restricted stock, the


                                         -20-

    acceleration of the accrual or vesting of any benefits under any Pension
    Plan or the acceleration or creation of any rights under any severance,
    parachute or change in control agreement).

         (xviii) No event has occurred in connection with which UDLP, any of
    its Subsidiaries or any UDLP Employee Benefit Plan, directly or indirectly,
    could be subject to any material liability (A) under any statute,
    regulation or governmental order relating to any UDLP Employee Benefit Plan
    or (B) pursuant to any obligation of UDLP or any of its Subsidiaries to

         5.      COVENANTS OF SELLERS.  Sellers jointly and severally covenant

         (a)     ACCESS.  Prior to the Closing, Sellers shall grant to Buyer or

    acquire any material assets or property, except in the ordinary course of
    business and in a manner consistent with past practice;

         (xiii)  amend in any materially adverse respect any Material Contract;
    or

         (xiv)   enter into any legally binding commitment to do any of the
    foregoing

PROVIDED, HOWEVER, that nothing in this Section 5(b) shall be construed to
prohibit, prevent or otherwise limit Sellers from settling accounts through, or
otherwise making, regular, tax or other special distributions in cash or
repayments of cash from UDLP to any Seller, to the extent that, unless otherwise
provided in this Agreement (including in Section 2(b)), any such distribution or
repayment is reflected on the Closing Statement; and PROVIDED FURTHER that,
except as set forth in Section 8(p), nothing in this Agreement shall require the
presence of any positive cash balance on the books or in the accounts of UDLP at
the Closing. 

         (c)     CONFIDENTIALITY.  Each Seller agrees that, after the Closing
Date, it shall, and shall use its reasonable efforts to cause its respective
directors, officers, employees, advisors and Affiliates to, keep the Information
(as defined below) confidential for a period of five years from the Closing
Date, except that any Information required by law or legal or administrative
process to be disclosed may be disclosed without violating the provisions of
this Section 5(c), and except that any Information may be used and disclosed (i)
in connection with the exercise or performance by Sellers of their respective
rights and obligations under or as permitted by the Ancillary Agreements and
(ii) (subject to reasonable and customary confidentiality protections, and
without jeopardizing the protection of trade secrets) in connection with the
development, manufacture, sale or distribution of any product outside of UDLP's
Scope of Activity, in each case without violating the provisions of this Section
5(c); PROVIDED, HOWEVER, that, with respect to Information that consists of
technical information, trade secrets or know-how, the covenants and obligations
of the Sellers in this Section 5(c) shall not terminate so long as such
technical information, trade secrets or know-how is or remains Information
subject to this Section 5(c).  At Buyer's request, each Seller shall use legal
action, including the commencement of litigation, if required, to enforce such
confidentiality obligations, and Buyer shall reimburse each such Seller for
reasonable out-of-pocket expenses (including the fees and expenses of counsel)
incurred in connection with such legal action as is requested by Buyer.  For
purposes hereof, the term "INFORMATION" means all information that relates to
UDLP, the Subsidiaries or the Foreign Affiliates or the Business, other than any
such information that is available to the public on the Closing Date, or
thereafter becomes available to the public other than as a result of a breach of
this Section 5(c), or is developed independently by Sellers or their respective
Affiliates after the Closing or is obtained from third parties who have no duty
of confidentiality to Buyer, UDLP or any of its Subsidiaries or Foreign
Affiliates.

         (d)     PRESERVATION OF BUSINESS.  Prior to the Closing, subject to
the terms and conditions of this Agreement, Sellers shall, and shall cause UDLP
and its Subsidiaries and, subject to applicable agreements with the minority
partners, Foreign Affiliates to, use reasonable best efforts consistent with
past practices to preserve the Business intact, to preserve the goodwill of
customers and suppliers of UDLP and to retain its key employees.

         (e)     COVENANT NOT TO COMPETE.  Each Seller agrees that, for a
period of six years following the Closing Date, it will not, and will cause each
of its Affiliates not to, engage, directly or indirectly, anywhere in the world
in any line of business within the Scope of Activity; PROVIDED, HOWEVER, that
(i) Harsco shall be entitled to continue to engage in the development,
manufacture, retrofit, installation, repair, overhaul, engineer, design,
service, sale and marketing of armor and armor kits for sale to the military and
other customers, (ii) Harsco shall be entitled to engage in activities
reasonably necessary to completing the termination and winding up of its former
truck and bus business and (iii) either Seller shall be entitled to engage in
the development, manufacture, retrofit, installation, repair, overhaul,
engineer, design, service, sale and marketing of any component part or subsystem
of military vehicle systems which are substantially the same as classes of
products or services that primarily are commercially sold by such Seller for
non-military uses.  If any court of competent jurisdiction shall finally hold
that the time, territory or any other provision set forth in this Section 5(e)
constitutes an unreasonable restriction, such provision shall not be rendered
void, but shall apply as to such time, territory or to such other extent as such
court may determine constitutes a reasonable restriction under the circumstances
involved.  Each Seller acknowledges that the restrictions contained in this
Section 5(e) are reasonable and necessary to protect the legitimate interests of
Sellers, UDLP and Buyer and that any breach by either Seller of any provision
hereof will result in irreparable injury to UDLP and Buyer.  Each Seller
acknowledges that, in addition to all remedies available at law, UDLP and Buyer
shall be entitled to equitable relief, including injunctive relief, and an
equitable accounting of all losses and damages.  For purposes of this Agreement,
the "SCOPE OF ACTIVITY" of UDLP shall be to engage in the development,
manufacture, retrofit, installation, overhaul, repair, engineering, design,
service, sale and marketing of any military vehicle system or weapon system or
station or component thereof.  It shall not be a violation of this provision for
either Seller to purchase or combine with an entity conducting a business that
has products and services that fall within the Scope of Activity but are
incidental to the business of such entity as a whole.  Each Seller further
agrees that it will not, for a period commencing on the date hereof and ending
two years following the Closing Date, kn
