deductible amounts of the relevant insurance policies and to complete the
purchase, in which event, all proceeds of insurance paid to Seller and all right
and claims of Seller to any such amounts not paid by the Closing Date shall be

              (c)    to terminate the Agreement if there is a Material Adverse

the Estimated Net Working Capital Amount exceeds, or is less than, the Target
Working Capital, then the Purchase Price payable on the Closing Date shall be
increased or reduced, as applicable, by the amount the Estimated Net Working
Capital Amount exceeds or is less than the Target Working Capital.

       3.5.   POST-CLOSING ADJUSTMENT.

              (a)    Within ninety (90) days after the Closing Date, Seller will
prepare (with the assistance of its independent certified public accountants if
Seller so elects ("SELLER'S AUDITORS")) and present to Buyer a calculation of
the Net Working Capital of the Business as of the Closing Date (the "PROPOSED
NET WORKING CAPITAL AMOUNT"), which shall be prepared consistent with the Target
Working Capital so that it presents fairly the Net Working Capital of the
Business as of the Closing Date using accounting methods, practices and
procedures as used in the preparation of the Target Working Capital. Buyer and,
if Buyer elects, a firm of independent certified public accountants selected by
Buyer (the "BUYER'S AUDITORS"), shall be given, together with the Proposed Net
Working Capital Amount, the workpapers and access to the books, records and
personnel of Seller and, if applicable, Seller's Auditors (the "WORKPAPERS"),
utilized in preparing the Proposed Net Working Capital Amount for purposes of
verifying the accuracy thereof. The Proposed Net Working Capital Amount shall be
binding upon the parties to this Agreement unless Buyer gives written notice of
disagreement with any of the values or amounts contained therein to Seller
within thirty (30) days after its receipt of the Proposed Net Working Capital
Amount and the Workpapers specifying in reasonable detail the nature and extent
of such disagreement. If Seller and Buyer mutually agree upon the Proposed Net
Working Capital Amount within thirty (30) days after Buyer's delivery of such
notice of disagreement, such agreement shall be binding upon the parties hereto
for purposes of this Agreement. If Seller and Buyer are unable to resolve any
such disagreement within such period, the disagreement shall be referred for
final determination to Ernst & Young L.L.P. (the "FIRST CHOICE") or, if such
firm is not available, such other independent accounting firm of national
reputation selected by the mutual agreement of Seller and Buyer (the "SELECTED
FIRM") and the resolution of the disagreement by the First Choice or the
Selected Firm, as the case may be, shall be final and binding upon the parties
hereto for purposes of this Agreement. If Seller and Buyer cannot agree on the
Selected Firm, it shall be chosen by the First Choice and shall be a nationally
recognized firm other than any accounting firm that has audited or been engaged
to audit the financial statements of Buyer or Seller within the two years
preceding the date of this Agreement. The Proposed Net Working Capital Amount as
finally determined is referred to herein as the "FINAL NET WORKING CAPITAL
AMOUNT." The fees and disbursements, if any, of Buyer's Auditors incurred in the
preparation of the Proposed Net Working Capital Calculation shall be paid by
Buyer. Seller shall pay the fees and disbursements, if any, of the Seller's
Auditors. The fees and disbursements, if any, of the First Choice or the
Selected Firm, as the case may be, shall be paid by Buyer and Seller, as the
First Choice or the Selected Firm, as the case may be, shall determine based
upon its assessment of the relative merits of the positions taken by each in any
disagreement presented to such firm.

              (b)    In the event the Final Net Working Capital Amount exceeds
the Estimated Working Capital Amount by more than $250,000, then within five (5)
business days after the final determination of the Final Net Working Capital
Amount, Buyer shall pay to Seller the difference between the Final Net Working
Capital Amount and the Estimated Net Working Capital Amount plus the Retention
(together with interest thereon at a rate of interest of three-month LIBOR as in
effect on the Closing Date from the Closing Date until the date of such
reimbursement) in immediately available funds by wire transfer to a bank account
designated in writing by Seller prior to the due date thereof.

              (c)    In the event the Estimated Net Working Capital Amount
exceeds the Final Net Working Capital Amount by more than $250,000, then within
five (5) business days after the final determination of the Final Net Working
Capital Amount, (i) Seller shall pay to Buyer the difference between the
Estimated Working Capital Amount and the Final Net Working Capital Amount and
(ii) Buyer shall pay to Seller the Retention (in the case of clauses (i) and
(ii) above, together with interest thereon at a rate of interest of three-month
LIBOR as in effect on the Closing Date from the Closing Date



                                     - 6 -

until the date of such reimbursement), in immediately available funds by wire
transfer to a bank account designated in writing by Buyer prior to the due date
thereof.

       3.6.   PURCHASE PRICE ALLOCATION.

              (a)    Buyer and Seller shall agree upon an allocation of the
Purchase Price among the Purchased Assets consistent with Section 1060 of the
Code and the Treasury Regulations thereunder within 30 days after the Closing
Date. If Buyer and Seller cannot agree on any such allocation, such dispute
shall be resolved in accordance with SECTION 3.5(b). The allocation required by
this SECTION 3.6 shall be revised based on any adjustment to the Purchase Price
pursuant to SECTION 3.6 within ten days after the final determination of the
Final Net Working Capital Amount. Each of Buyer and Seller agrees to file Form
8594 as required by Section 1060 of the Code, and all federal, state, local and
foreign Tax Returns, in accordance with any such agreed allocation as adjusted
as provided herein. Each of Buyer and Seller shall report the transactions
contemplated by this Agreement for federal Tax and all other Tax purposes in a
manner consistent with any such allocation determined pursuant to this SECTION
3.6. Each of Buyer and Seller agrees to provide the other promptly with any
information required to complete the Form 8594. Buyer and Seller shall notify
and provide the other with reasonable assistance in the event of an examination,
audit or other proceeding regarding any allocation of the Purchase Price
determined pursuant to this SECTION 3.6. Buyer and Seller shall not take any
position in any Tax Return, Tax proceeding or audit that is inconsistent with
such allocation.

              (b)    In the event that a dispute arises between Seller and Buyer
as to any allocation of Purchase Price under SECTION 3.6(a), Buyer and Seller
shall attempt in good faith to resolve such dispute. If such dispute is not
resolved within 30 days thereafter, Buyer and Seller shall submit the dispute to
the First Choice or the Selected Firm, as the case may be, for resolution with
each party presenting its position, which resolution shall be final, conclusive
and binding on Buyer and Seller. Notwithstanding anything in this Agreement to
the contrary, the fees and expenses of the First Choice or the Selected Firm, as
the case may be, in resolving the dispute shall be borne equally by Buyer and
Seller.

have a Material Adverse Effect, and there is no reasonable basis for any such
assertion.

allocation or sharing agreement that would affect Taxes attributable to the

Seller shall not engage in any practice, take any action, or enter into any
transaction outside of the ordinary course of business. Without limiting the
generality of the foregoing, Seller will not (i) take any action, or enter into
any transaction with respect to the Purchased Assets or Assumed Liabilities
outside the ordinary course of business, the primary purpose or effect of which

or fail to take any action that would cause any of the other representations,
warranties or covenants contained herein to be untrue or incorrect or incapable
of being performed or satisfied on the Closing Date.

       6.3.   UPDATES.

              Seller shall promptly notify Buyer of the occurrence after the

Agreement); provided, however, that such confidentiality obligation shall not
apply to (a) disclosure to the extent necessary to meet the requirements of
Applicable Law (subject to giving Seller notice as promptly as possible of the

protective order), or (b) any information which (i) was already in Buyer's
possession from a source other than Seller and without an obligation of
confidentiality prior to the disclosure thereof by Seller or its agents, (ii)

approval that is required in order to transfer or assign any Purchased Asset,
including any Contract included in the Purchased Assets, the parties shall enter
into such mutually acceptable arrangement as is necessary to provide Buyer with
the benefits thereof and, with respect to any such Contracts, Buyer shall pay
and perform all obligations of Seller thereunder after the Closing Date.

       7.3.   ASSIGNMENT OF CONTRACTS AND RIGHTS.

              (a)    Noncontravention. Anything in this Agreement to the
contrary notwithstanding, this Agreement shall not constitute an agreement to
assign any Contract or any claim, right or benefit arising thereunder or
resulting therefrom if an attempted assignment thereof, without the consent of a
third party thereto, would constitute a breach or other contravention thereof,
be ineffective with respect to any party thereto or in any way adversely affect
the rights of Buyer or Seller thereunder.

              (b)    Government Contract Assignments and Novations. With respect
to any Government Contract and any claim, right or benefit arising thereunder or
resulting therefrom, Seller and Buyer will use reasonable good faith efforts to
obtain as expeditiously as possible, if required, the written consent of the
other parties to such Government Contract for the assignment or, if required,
novation thereof to Buyer or, alternatively, written confirmation from such
parties reasonably satisfactory in form and substance to Buyer and Seller that
such consent is not required. In furtherance of the foregoing, (i) with respect
to the Prime Government Contracts to which Seller is a party, as soon as
practicable following the Closing, Buyer and Seller shall submit to the relevant
Responsible Contracting Officer a written request that the relevant Governmental
Authority enter into a Government Contract Novation with Buyer with respect to
such Prime Government Contracts; and (ii) with respect to each Government

soon as practicable



                                     - 22 -

following the date hereof, submit to the other party or parties thereto
documentation seeking the written waiver or approval of such other contracting
party or parties thereto to the transfer and assignment of all of Seller's
claims, rights, benefits and liabilities thereunder to Buyer. In this regard,
Seller and Buyer shall take all actions required or customary under any FAR
provision (or applicable equivalent regulation).

              (c)    Buyer Responsibility. Notwithstanding any other provision
of this Agreement, the failure by the parties to obtain any required Government
Contract Novation, or any similar consent, waiver, confirmation, novation or
approval with respect to any Government Contract, shall not relieve either party
from its obligation to consummate at the Closing the transactions contemplated
by this Agreement. Buyer acknowledges that (i) a substantial portion of the
Government Contracts will require the consent or, in the case of Prime
Government Contracts, Government Contract Novation, of the other party or
parties thereto by virtue of the execution and delivery of this Agreement or the
consummation of the transactions contemplated hereby and (ii) with respect to
any Bids submitted by Seller before the Closing, the responsible contracting
office might not, after the Closing, award a contract to Buyer based on such Bid
until such responsible contracting officer determines that Buyer, as a result of
its purchase of the Business, is Seller's successor in interest to such Bid.
Buyer agrees and acknowledges that it shall be the obligation of Buyer (and not
Seller) to obtain the consents and authorizations described in this SECTION
7.3(c). Seller will, however, use commercially reasonable efforts to assist
Buyer in obtaining such consents.

              (d)    Subcontract and Other Arrangements. If any Government
Contract Novation or any consent, waiver, confirmation, novation or approval
described in this SECTION 7.3 is not obtained with respect to any Contract, then
Seller and Buyer will cooperate to establish an arrangement reasonably
satisfactory to Buyer and Seller under which Buyer would obtain, to the extent
practicable, the claims, rights and benefits and assume the corresponding
liabilities and obligations thereunder in accordance with this Agreement
(including by means of any subcontracting, sublicensing or subleasing
arrangement) or under which Seller would enforce for the benefit of Buyer, with
Buyer assuming and agreeing to pay Seller's obligations, any and all claims,
rights and benefits of Seller against a third party thereto.

       7.4.   LETTERS OF CREDIT; SURETY BONDS.

              On or prior to the Closing Date, Buyer and Seller will use
commercially reasonable efforts to ensure that Seller and its Affiliates are
released from all obligations under all letters of credit, surety and
performance bonds, guarantees and other financial support arrangements relating
to the Business that either (a) are set forth in SCHEDULE 7.4 or (b) are
provided or otherwise become effective after the date of this Agreement and not
in contravention of the terms of this Agreement (the "LETTERS OF CREDIT"). If
Buyer is unable to obtain any such release from any such arrangement by the
Closing, at and after the Closing Date, Buyer and Seller will continue to use
commercially reasonable efforts to ensure that Seller and its Affiliates are
released from such arrangements. In the event such release is not obtained
within 90 days after the Closing Date, Buyer shall provide replacement
irrevocable letters of credit from a bank reasonably acceptable to Seller (and
Parent shall guarantee such letters of credit, if necessary) and containing
terms and conditions reasonably acceptable to Seller pursuant to which the
beneficiaries thereof are indemnified against all of their respective
obligations under any such arrangement from which such beneficiary is not so
released on the Closing Date.

       7.5.   EMPLOYMENT; EMPLOYEE BENEFITS.

              (a)    Existing Employees. Prior to the Closing, Buyer shall
extend an offer of employment to each Existing Employee for a comparable
position at the same salary or hourly wage as in effect with respect to such
employee on the Closing Date. (For purposes of this Agreement, any such Existing
Employee who accepts an offer of employment is referred to as a "TRANSFERRED
EMPLOYEE.") Subject to the other provisions of this SECTION 7.5, the Transferred
Employees shall be employed after the Closing in accordance with, and subject
to, Buyer's usual terms, conditions and policies of employment.

              (b)    Transferred Employee Benefit Plans.

                     (i)    Except as otherwise set forth in this SECTION
7.5(b), immediately following the Closing Date, the Transferred Employees,
during such time as their employment with Buyer is continued, shall be eligible
to participate in Buyer's employee benefit plans ("BUYER BENEFIT PLANS") on the
same terms and conditions as similarly situated employees of Buyer are eligible
to participate therein. Specifically, Buyer shall make available to each of the
full-time Transferred Employees (i) life, accidental death and dismemberment,
long-term disability and short-term disability insurance benefit plans to become
effective on the Closing Date and (ii) medical, dental and vision insurance
benefit plans to become effective not later than December 31, 2000. Buyer shall
cause the Buyer Benefit Plans to recognize prior service of Transferred
Employees under corresponding Seller's benefit plans prior to the Closing as
service with Buyer and its Affiliates for purposes of (i) any Buyer Benefit Plan
that is not a Pension Plan for purposes of any waiting period and eligibility
requirements and (ii) any Buyer Benefit Plan that is a Pension Plan, for
purposes of eligibility (including eligibility for early retirement benefits)
and vesting (but not benefit accrual) thereunder. Seller shall continue to
provide benefit coverage to all Transferred Employees under Seller's benefit
plans until the Closing. Buyer shall assume the liabilities specifically
reflected on the Interim Balance Sheet that are attributable to the Transferred
Employees. Except as otherwise set forth in this SECTION 7.5(b), Buyer shall
assume all liabilities, responsibilities and obligations under the Buyer Benefit
Plans with respect to the Transferred Employees for the provision of any
benefits otherwise available under such plans, including, without limitation,
comprehensive health, dental or drug welfare benefits otherwise payable with
respect to any covered health, dental, and/or covered services and/or materials
and/or supplies and/or expenses, which were provided to or are incurred after
the Closing.

                     (ii)   Seller shall provide continued health and medical
coverage to the extent required under Section 4980B of the Code, Part 6 of Title
I of ERISA or any other applicable federal, state or local law or ordinance
("COBRA COVERAGE") to all Transferred Employees (including their eligible
dependents and beneficiaries) with respect to whom a "qualifying event" (as such
term is defined under Sections 4980B(f)(3) of the Code or 603 of ERISA) or other
triggering event described under the applicable federal, state or local laws or
ordinances occurs on or before the Closing; provided that Buyer shall pay Seller
all premiums in respect of COBRA Coverage for the Transferred Employees as such
premiums become due. In addition to such premiums, Buyer shall promptly
reimburse Seller for (i) any claims paid by Seller under Seller's dental or
medical benefit plans to Transferred Employees for claims incurred by
Transferred Employees (including their eligible dependents and beneficiaries)
during the period beginning on the Closing Date and ending on and including the
last day of the calendar month in which the Closing occurs and (ii) all
out-of-pocket expenses associated with Seller's provision of COBRA Coverage to
the Transferred Employees (including their eligible dependents and
beneficiaries) for the period commencing on the Closing Date and ending on
December 31, 2000.

              (c)    Other Buyer and Seller Responsibilities. Seller agrees that
on and after the Closing, Buyer shall assume no liability, obligation or
commitment with respect to Seller's benefit plan or any benefits or other
amounts payable or provided under any Seller's benefit plan or any notice
(including, but not limited to, notice required by the WARN Act (except with
respect to Transferred Employees or COBRA)), or any Contract relating to
employment or termination of employment between Seller and any of its employees
or former employees, including the Transferred Employees, except with respect to
any contracts arising between Buyer and any Transferred Employee. Buyer agrees
that on and after the Closing, Seller shall assume no liability, obligation or
commitment with respect to any benefit plan of Buyer or any benefits or other
amounts payable or provided under any Buyer's benefit plan or any contract
relating to employment or termination of employment between Buyer and any of its
Affiliates and any of their employees or former employees, including the
Transferred Employees.

              (d)    Further Assurances. Seller and Buyer shall take such
further action (before, at or after the Closing Date), if any, as reasonably may
be necessary or convenient to implement the intent of their agreements contained
in this SECTION 7.5. Seller shall make available to Buyer such information as
Buyer may reasonably request to enable Buyer to determine such matters relating
to employment and salary histories for purposes of the Buyer Benefit Plans.

              (e)    No Third Party Beneficiary. No provision of this SECTION
7.5 shall create any third party beneficiary rights in any employee or former
employee (including any beneficiary or dependent thereof) in respect of
continued employment (or resumed employment) or any other matters and no
provision of this SECTION 7.5 shall create any such rights in any such persons
in respect of any benefit plan or arrangement.

              (f)    Retention Plans. Set forth on SCHEDULE 7.5(f) is a
description of Seller's employee retention plans (the "RETENTION PLANS").
Effective upon the Closing, Buyer shall assume and continue to maintain the
Retention Plans for those employees of Seller (and former employees of Seller)
covered thereby at the Closing Date who are Existing Employees and pay all
amounts to which any such individuals may become entitled thereunder after the
Closing Date.

              (g)    401(k) Plan. As soon as administratively practicable after
the Closing Date, Seller shall cause the trustee of Seller's 401(k) plan to
transfer to the trustee of Buyer's 401(k) Plan, in a trustee-to-trustee
transfer, cash, securities, outstanding loan balances, or a combination thereof
equal to the account balances of all Transferred Employees. Buyer shall cause
the trustee of its 401(k) plan to accept the transfer from the trustee of
Seller's 401(k) plan, and Buyer shall credit the accounts for the Transferred
Employees under its 401(k) Plan with the amounts on a fully vested basis, if
any, transferred on their behalf. The transfers required by this SECTION 7.5(g)
shall comply with Section 414(l) of the Internal Revenue Code and the
requirements of ERISA and the regulations promulgated thereunder.

              (h)    Spending Accounts. This Section shall apply if Buyer shall
maintain a plan or plans under Section 125 and Section 129 of the Internal
Revenue Code in which Transferred Employees are eligible to participate during
the 2000 calendar year ("BUYER'S SECTION 125 PLAN") and such Transferred
Employees also participated in the corresponding plans of the Seller (the
"SELLER'S SECTION 125 PLAN") during the 2000 calendar year. At the end of the
2000 year, the following adjustments shall be made between Buyer and Seller:

                     (i)    If the aggregate amount contributed by Transferred
Employees for 2000 to the Transferred Employees' spending accounts under
Seller's Section 125 Plan exceeds the aggregate claims paid by Seller for 2000
with respect to the Transferred Employees' spending accounts, Seller shall



                                     - 25 -
<PAGE>   31

pay Buyer an amount in cash equal to such excess to the extent that the
aggregate amount contributed by Transferred employees for 2000 to their spending
accounts under Buyer's Section 125 Plan is less than the aggregate claims paid
by Buyer for 2000 with respect to the Transferred Employees' spending accounts.

                     (ii)   If the aggregate amount contributed by Transferred
Employees for 2000 to their spending accounts under Seller's Section 125 Plan is
less than the aggregate claims paid by Seller for 2000 with respect to the
Transferred Employees' spending accounts, Buyer shall pay Seller an amount in
cash equal to such deficit, to the extent that the aggregate amount contributed
by Transferred Employees for 2000 to the Transferred Employees' spending
accounts under Buyer's Section 125 Plan exceeds the aggregate claims paid by
Buyer for 2000 with respect to the Transferred Employees' spending accounts.

                     (iii)  The foregoing payments shall be made as soon as
practicable after all claims have been paid for the 2000 year.

       7.6.   TAX RETURNS.

              (a)    Seller Returns Prior to Closing. Seller shall prepare or
cause to be prepared and file all Tax Returns and pay all Taxes with respect to
Taxes constituting Excluded Liabilities for all taxable periods beginning on or
prior to the Closing Date and ending on or after the Closing Date when such Tax
Returns or Taxes are due, even though such Tax Returns or Taxes are not due
until after the Closing Date. Such Tax Returns shall be prepared and filed in a
manner consistent with prior returns.

              (b)    Cooperation After Closing. After the Closing Date, Seller
and Buyer shall, as may be reasonably requested by Buyer, on the one hand, or
Seller, on the other hand:

                     (i)    assist the other party in preparing any Tax Returns
or reports which such other party or parties is or are responsible for preparing
and filing with respect to the Business;

                     (ii)   cooperate fully in preparing for any audits of, or
any disputes with taxing authorities regarding, any Tax Returns of or including
the Business; and

                     (iii)  retain and make available to the other party and to
any taxing authority all information, records and documents reasonably requested
relating to Taxes of the Business.

       7.7.   LIABILITY FOR TRANSFER TAXES.

              Buyer shall be responsible for the timely payment of, and shall
indemnify and hold harmless Seller and its Affiliates against, all sales
(including, without limitation, bulk sales), use, value added, documentary,
stamp, gross receipts, registration, transfer, conveyance, excise, recording,
license and other similar Taxes and fees ("TRANSFER TAXES") arising out of or in
connection with or attributable to the transactions affected pursuant to this
Agreement. Buyer shall prepare and timely file all Tax Returns required to be
filed in respect of Transfer Taxes. Buyer's preparation of any such Tax Returns
shall be subject to Seller's approval, which approval shall not be withheld
unreasonably. Seller shall file all required sales tax notifications as promptly
as practicable following the date hereof and shall provide to Buyer copies of
any such filings. Seller and Buyer shall use all reasonable efforts to minimize
the amount of all Transfer Taxes and cooperate in providing each other with the
information necessary to prepare and review such Tax Returns.

any derivation therefrom or any corporate symbols or logos incorporating such
names either alone or in combinations (collectively, the "ORBITAL NAME RIGHTS")
from any advertisements, web sites, mail addresses, domain name services,

workpapers, drawings, memoranda or similar property that is not released to
third parties in the ordinary course. During the 180 day period following the

Closing, Seller or Buyer receives, or comes into possession of, any of the
Purchased Assets or Excluded Assets or any receipts, proceeds, checks,
securities or other property of any kind comprising, arising out of or derived
from the Purchased Assets or the Business or Excluded Assets (including any
check, notes or cash in payment of any account receivable or other intangible
constituting part of the Purchased Assets or Excluded Assets), Seller or Buyer,
as applicable, shall immediately deliver the same to the appropriate party, with
such endorsements, transfers or assignments as may be necessary or desirable to
ensure that such party receives the immediate and full benefit thereof.

              (b)    Shared Assets. Without limiting the definition of the
Purchased Assets or Buyer's rights to the Purchased Assets hereunder, Seller and
Buyer shall cooperate in good faith to resolve any disputes as to whether any
specific assets owned by Seller, other than the Purchased Assets, that relate to
the Business and another business of Seller are used in or relate to the
Business. Further, without limiting the foregoing, with respect to any asset
presently used in connection with the Business that is also used by Seller in
connection with a business of Seller other than the Business, (i) the parties
shall cooperate in good faith to determine which business predominantly uses
such asset, (ii) if appropriate, the parties shall agree to transfer title to
that asset to the party that owns the business that predominantly uses such
asset, (iii) without limiting Seller's continued use, if appropriate, the
parties shall otherwise coordinate the nonexclusive use of the asset by Buyer,
and (iv) with respect to any proprietary Know-How and Intellectual Property
(other than the Excluded Assets) used by Seller in the Business but not included
in the Purchased Assets, Seller hereby grants Buyer a nonexclusive perpetual,
nonassignable (other than to Smiths Industries plc or subsidiaries thereof)
royalty-free license to use such Know-How and Intellectual Property on an as is
basis. With respect to any Contract applicable to both the Business and such
other business of Seller, Seller and Buyer shall cooperate to structure
contractual arrangements to such agreement providing both Seller and Buyer with
appropriate rights and obligations for shared use. Such contractual arrangements
may take the form of a subcontract, sublicense or two separate agreements.

              (c)    Audits. Following the Closing Date, Seller and Buyer shall
cooperate reasonably with each other in connection with any audit or review by
any Governmental Authority or other party with respect to the Business. Upon
reasonable request, at the expense of the party requesting assistance, each
party will make available appropriate personnel and provide pertinent records to
enable the other party to assist in any such audit or review.

the transition of the employees, payroll, management information systems,
e-mail, computer systems, customers and Contracts, and other assets.

       7.10.  BOOKS AND RECORDS.

              On or prior to the Closing Date, Seller shall provide copies of
the books, records and files of Seller retained by Seller and described in
SECTION 1.3(h). Following the Closing Date, Seller shall make such records
available to Buyer as may be reasonably requested by Buyer for purposes of
compliance with Applicable Laws; provided, however, that Seller shall not be
liable to Buyer in the event of any destruction of such records unless Seller
fails to maintain such records with the same degree of care with which Seller
maintains other similar records.

       7.11.  NONCOMPETITION.

              (a)    Nonsolicitation. Seller agrees that it will not, and will
cause its subsidiaries not to, at any time during the period of two (2) years
following the Closing Date, directly or indirectly, solicit for employment or
retention of, in any capacity, any Transferred Employee; provided that this
covenant shall not apply to the general advertisement of employment
opportunities. Buyer and Parent agree that they will not, and will cause their
subsidiaries not to, at any time during the period of two (2) years following
the Closing Date, directly or indirectly, solicit for employment or retention
of, in any capacity, any employee of Seller; provided that this covenant shall
not apply to the general advertisement of employment opportunities.

              (b)    Noncompetition. Seller will not, and will cause its
subsidiaries not to, for a period of three (3) years following the Closing Date,
directly or indirectly, engage in the design or production of sophisticated
electronics, avionics and mission management systems for use in military
aircraft, helicopters and land vehicles of the type currently designed or
produced in or by the Business (a "COMPETING BUSINESS"); provided that this
SECTION 7.11 shall not (i) prevent Seller or any of any of its subsidiaries from
engaging in any activities that Seller or any of its subsidiaries is engaged in
outside of the Business immediately before the Closing Date, (ii) prohibit the
acquisition (by merger or otherwise) of the securities or assets of a business
where the gross revenues of such business attributable to a Competing Business
constitute less than twenty percent (20%) of the total gross revenue of such
business or (iii) prevent MacDonald, Dettwiler and Associates Ltd. from engaging
in any business.

              (c)    Enforceability. Seller and Buyer acknowledge and agree that
in view of the nature of the Business and the business objectives of Buyer and
Seller in the transactions contemplated by this Agreement, the foregoing
limitation is reasonable and properly required for the adequate protection of
Buyer and Seller and that in the event that such limitation is deemed to be
unreasonable, then such limitations shall be automatically reduced to the
maximum extent permitted by a court of competent jurisdiction and, as reduced,
the limitation shall be enforced.

              (d)    Equitable Remedies. Seller and Buyer acknowledge that a
violation of this SECTION 7.11 may cause irreparable injury to the non-breaching
party and that the non-breaching party shall be entitled, in addition to any
other rights and remedies it may have, to injunctive relief without being
required to prove actual damages or post bond.

indemnification based upon clause (a) of SECTION 13.1 until the aggregate amount
of Buyer Damages for which indemnification is available under such clause (a)
exceeds $500,000 (the "BUYER THRESHOLD"), whereupon Buyer Indemnitees shall be
entitled to seek indemnification for the amount of such Buyer Damages (including
without limitation those included in the Buyer Threshold); provided, however,
that such limitation shall not apply to any liability for indemnification with
respect to any claim for indemnification based upon (i) fraud, (ii) any
misrepresentation or breach of a warranty which was actually known to be untrue
by Seller when made, or (iii) any misrepresentation or breach of a warranty
contained in SECTION 4.6 (Taxes). Notwithstanding the foregoing, in no event
shall the aggregate liability of Seller under this ARTICLE 13 with respect to
any



                                     - 34 -
<PAGE>   40

claim for indemnification based upon clause (a) or clause (b) of SECTION 13.1

indemnification based upon clause (a) of SECTION 13.2 until the aggregate amount
of Seller Damages for which indemnification is available under such clause (a)
exceeds $500,000 (the "SELLER THRESHOLD"), whereupon Seller Indemnitees shall be
entitled to seek indemnification for the amount of such Seller Damages
(including without limitation those included in the Seller Threshold); provided,
however, that such limitation shall not apply to any liability for
indemnification with respect to any claim for indemnification based upon (i)
fraud, or (ii) any misrepresentation or breach of a warranty which was actually
known to be untrue by Buyer when made. Notwithstanding the foregoing, in no
event shall the aggregate liability of Buyer under this ARTICLE 13 with respect
to any claim for indemnification based upon clause (a) or clause (b) of SECTION
13.2 exceed fifteen percent (15%) of the Purchase Price; provided that such 15%
limit shall not apply to (and in determining if such cap has been met, shall not
take into account) any claim based on the failure of Buyer to comply with its
obligations to (A) pay the Purchase Price pursuant to Section 3, or (B) pay
Transfer Taxes pursuant to SECTION 7.7.

       13.5.  EXCLUSIVE REMEDY.

              The parties acknowledge that, except in the case of fraud, their

Seller hereby waive any statutory, equitable or common law rights relating to
any Environmental Liabilities and Costs.

agreement in this Agreement and except that the agreements with respect to
