amended (collectively, "Excluded Assets"). The Purchased Assets and Excluded
Assets are collectively referred to herein as "Assets."

        1.3     Consideration. In consideration for the sale, assignment, 
transfer and delivery of the Purchased Assets Maxwell and MSD shall:

                (a)     deliver Ten Million Dollars ($10,000,000), less the
Holdback amount (as defined in Section 1.12) payable in immediately available
funds at the Closing, and

                (b)     assume the Assumed Liabilities (as such term is defined
below in Section 1.6), and

                (c)     perform the promises and covenants contained herein
(collectively the "Purchase Price").

        1.4     Change in Net Book Value.

                (a)     The Company has prepared (i) a balance sheet of the EMS
Group as of June 30, 1997 (the "June 30 Balance Sheet"), a copy of which is
attached hereto as part of Schedule 2.9. The parties to this Agreement hereby
agree that the "June 30 Net Book Value" of the EMS Group is equal to the
difference between the assets and liabilities of the EMS Business on June 30,
1997, as shown on the June 30 Balance Sheet, and the parties agree that the
adjusted June 30 Net Book Value is $5,084,000. Within ninety (90) days following
the



                                        3
<PAGE>   11

Closing Date, MSD shall deliver a balance sheet (the "Closing Balance Sheet") of
the EMS Group as of the Effective Date, which shall show the net book value of
the EMS Business as of the Effective Date (the "Closing Net Book Value"). The
Closing Balance Sheet (and on the Final Closing Balance Sheet, as such term is
defined below, as applicable) will be prepared in the same manner and in
accordance with the same accounting principles consistently applied (including
but not limited to treatment of net book value) as the June 30 Balance Sheet.
MSD shall provide the Company with all working papers used to prepare such
Closing Balance Sheet and any adjustments thereto under Section 1.5 hereof. In
the event that the Closing Net Book Value is less than the June 30 Net Book
Value, the Purchase Price shall be decreased dollar for dollar by the difference
between the Closing Net Book Value and the June 30 Net Book Value
("Adjustment"). If the Purchase Price is subject to an Adjustment, then within
thirty (30) days of the later of the date the Closing Balance Sheet is delivered
(and all related work papers are made available) to the Company, or the date
that any dispute regarding the Closing Balance Sheet is resolved, the Company
shall pay to MSD's account via wire transfer the amount of the Adjustment. In
the event that the Closing Net Book Value is greater than the June 30 Net Book
Value, PPI shall retain an aggregate value of accounts receivable in at least
the amount of excess so that the Closing Net Book Value does not exceed
$5,084,000 (the "Retained Receivables"). The Retained Receivables shall consist
of both billed and unbilled accounts receivable in the same ratio as the
division between billed and unbilled on the Closing Balance Sheet. As and when
MSD collects Accounts Receivable, that percentage of the amount collected equal
to the percentage determined by comparing the aggregate amount of Retained
Receivables to the aggregate amount of all billed and unbilled accounts
receivable of the EMS Business as of March 29, 1998, shall be paid to PPI by
MSD, subject to Section 9.7.

                (b)     Certain Procedures to be Used in Preparation of Closing
Balance Sheet. The following procedures shall be used in compiling the Closing
Balance Sheet, and in objecting to items addressed in this subsection (b):

                        (i)     Reserves for Contract Completion and Warranty.
MSD shall book those reserves for contract completion and warranty related to
the FEMPS 2000 Contract (as defined in Schedule 2.11) and as further set forth
with respect to the December 31 Balance Sheet on Schedule 1.4(b), and consistent
with MSD's past business practices. If PPI does not consent to these reserves,
PPI shall have the option, but not the obligation, of assuming in writing all
liability for all contract completion or warranty reserves that are proposed by
MSD, and such reserves shall be removed from the Closing Balance Sheet, and MSD
will bill PPI for any expenses incurred by MSD with respect to such liabilities.
MSD shall certify that MSD will so bill under accounting principles consistent
with the accounting principles under which the Financial Statements were
prepared, and PPI shall have the right to audit such statements (at its own
expense) and to contest any amount related to contract completion and warranty
reserve billings to PPI under Section 1.5.

                        (ii)    Reserves for Accounts Receivable. MSD shall not
book any reserve for uncollectible Accounts Receivable and all disputes shall be
addressed as set forth in Section 9.7.



                                        4
<PAGE>   12

                        (iii)   Reserves for Inventory Obsolescence. MSD shall
book a reserve for inventory obsolescence in the amount shown on Schedule
1.4(b). For two years after the Effective Date, when MSD sells inventory in
existence on the Effective Date, MSD shall pay PPI in cash an amount
representing (a) the percentage reserved on such inventory multiplied by (b) the
original cost of such inventory. All value received on such inventory in excess
of cost shall be retained by MSD.

        1.5     Disputes as to Closing Balance Sheet. If the Company disagrees
with the Closing Balance Sheet, or any particular items listed therein, the
disagreement shall be set forth in detail in writing and delivered to MSD and
the other parties hereto under the notice provisions of this Agreement within
thirty (30) days after receipt by the Company of the Closing Balance Sheet and
all related work papers. The Company and PPI shall be deemed to agree with all
line items of the Closing Balance Sheet not objected to specifically in such
written notice, and if no notice is delivered, the Company and PPI shall be
deemed to agree with the Closing Balance Sheet in full. MSD shall have ten (10)
business days to consider such objections and make any adjustments it deems
necessary in light of the objections. If adjustments are not made to the Closing
Balance Sheet, or if the Company objects even though an adjustment is made, the
parties hereto shall meet and confer and attempt to resolve the differences
amicably. If the parties shall not agree, the Closing Balance Sheet, the notices
of objection and any subsequent adjustments shall be submitted by the parties to
final and binding arbitration. To commence arbitration, the initiating party
shall deliver written notice demanding arbitration to the other party or
parties. If the parties fail to select an arbitrator within ten (10) days of the
date on which arbitration is demanded by the initiating party, any party may
request the appointment of an arbitrator by the American Arbitration Association
in San Francisco, California, and each party hereby agrees to submit to such
arbitrator's jurisdiction. Any arbitration hearing shall commence, if at all
possible, within ten (10) business days after selection of the arbitrator (the
"Arbitrator") and shall, to the extent possible, continue from day to day
thereafter until concluded. The Arbitrator must be a certified public accountant
then employed by a "Big Six" accounting firm and with at least ten (10) years of
experience. The Arbitrator or his or her firm shall not be related to, have had
business dealings with or have provided services to any party or their
affiliates. The Arbitrator shall conduct such review of (i) the books and
records of PPI and the EMS Group as of Closing, (ii) the Closing Balance Sheet,
(iii) the objections and (iv) any subsequent adjustments thereto as he or she
deems necessary or relevant to a determination as to the items subject to
dispute on the Closing Balance Sheet and shall render a decision on the
Company's objections which shall not be more favorable to the Company or PPI
than requested in any objection to the Closing Balance Sheet. The Closing
Balance Sheet, as adjusted pursuant to the Arbitrator's decision, shall be
termed the "Final Closing Balance Sheet," and the Final Closing Balance Sheet
shall be conclusive and binding and not subject to challenge or appeal before
any court or tribunal. The Closing Net Book Value shall then be computed
therefrom. The Company or PPI shall pay the fees and costs of the Arbitrator
unless the increase in Closing Net Book Value is at least $50,000 more favorable
to the Company and PPI than would have been the net book value using the Closing
Balance Sheet, in which case MSD will pay the fees and costs of the Arbitrator.

occurring at any time following the Closing, except to the extent expressly

Except for the liabilities and obligations listed in the previous sentence, and

of the transactions contemplated hereby, any of the liabilities, obligations or

order to which the EMS Business was subject;

                (c)     for any indebtedness of PPI or the Company other than

rates charged prior to Closing) to which customers of PPI or the Company may be
entitled in connection with the operation of the EMS Business prior to the
Closing in excess of reserves for adjustments reflected on the Closing Balance
Sheet;



                                        6
<PAGE>   14

                (e)     except as set forth on Schedule 1.6(c), under or arising
under any relevant law, statute, rule, regulation, decree, order or judgment,
contracts or otherwise relating to current or former employees of the EMS Group
with respect to any claim, circumstance or event, course of conduct or otherwise
(actual or alleged) for any period of time prior to the Closing Date or under
any employee fringe, retirement or other benefit plans (including deferred

prior to the date of the Closing, including without limitation all such claims
identified on Schedules 2.17 (Litigation) and 2.18 (Environmental);

business of the OTS division of PPI;

                (i)     to any EMS Group employee as a result of the alleged
termination of such employee on or prior to the Closing Date, whether or not
such alleged termination is in connection with the transactions contemplated
hereby, including specifically severance obligations reflected on the June 30
Balance Sheet or Closing Balance Sheet, as the case may be, which the parties
agree are Excluded Liabilities;

                (j)     resulting from any environmental damage or loss relating
to any property owned or used in connection with the EMS Business, whether
occurring prior to Closing or discovered after the date of the Closing if
arising from a condition or circumstance existing prior to the date of Closing
(and not from any act or omission by Maxwell and/or MSD at any time following
the Closing);

                (k)     for any product liability claim relating to a product
shipped, system installed or service provided prior to the Closing; or

                (l)     accruing, arising or related to an event occurring prior
to the Closing, except to the extent expressly assumed by MSD hereunder.

shall be delivered post-Closing). MSD and the Company agree that each will
report the federal, state and local income and other tax consequences of the
purchase and sale contemplated hereby in a manner consistent with such

examination of any tax return, in any refund claim, in any litigation, or
otherwise.

        1.9     Employees. MSD hereby agrees to employ the EMS Group's employees
(collectively the "EMS Employees" and each an "EMS Employee") at the same level
of compensation (other than benefits) for each EMS Employee as the respective
EMS Employee received immediately prior to the Closing. The EMS Employees are
listed on Schedule 1.9. It is expressly understood and agreed that:

                (a)     MSD shall not be restricted from hiring any employees of
the EMS Group terminated immediately prior to Closing in connection with the
transaction contemplated hereby. Except as provided herein, all terms and
conditions of the employment of any person hired by MSD are matters within MSD's
sole discretion, it being expressly understood that MSD reserves full right
(among others) to terminate the employment of such persons at any time and to
change the benefits provided to its employees at any time.

                (b)     MSD is not a successor or joint employer by virtue of
anything in this Agreement, or any other accord or understanding with the
Company or PPI or any thing done or not done by the Company or PPI pursuant to
this Agreement and MSD shall not, solely by virtue of this Agreement, be
obligated or responsible for performance of any terms of any labor agreement
applicable to any of the EMS Group's employees, salaried or hourly.

                (c)     MSD is not assuming, under this Agreement or otherwise,

obligation, responsibility or liability, whether contractual or statutory,
arising out of PPI's termination of employment of such employees of the EMS
Business and including without limitation any liability or obligation with
respect to wages, salaries, bonuses, health care plans or employee benefit plans
or any other compensation arrangement of any nature whatsoever which arise from
or relate to any person's employment by the EMS Group, or for any "Employee
Pension Benefit Plan" or "Employee Welfare Benefit Plan" as defined in Sections

1974, as amended ("ERISA"), sponsored or maintained by PPI or the Company,
except as otherwise set forth on Schedule 1.6(c) or (d). MSD shall not be
obligated to continue any employee benefit plans or arrangements of any nature
whatsoever presently or previously sponsored or maintained by PPI or the
Company.

                (d)     Any persons employed in the EMS Business by the EMS
Group who accept MSD's offer of employment will be hired on the Closing Date.
The service hours accrued by any individual during their employment by the
Company or PPI will be recognized by MSD for purposes of eligibility for

                (e)     MSD shall, at PPI's option, to be exercised by PPI at
its sole discretion by written notice to MSD at any time prior to Closing,
either: (i) accept a Trust to Trust transfer of vested funds of the EMS
Employees from the Primex Prime retirement-savings plan (the "Primex Plan") to
MSD's retirement-savings plan (the "Maxwell Plan"), or (ii) accept IRA rollovers
from individual EMS Employees who have taken a distribution of their Primex Plan
vested account balances to the Maxwell Plan at any time (consistent with
applicable law) following termination of the respective EMS Employee's
employment by PPI. MSD agrees to establish a flexible spending account (an "FSA
account") for each EMS Employee who currently has an FSA account with PPI. MSD
also agrees to accept transfer of funds from the PPI FSA account into the MSD
FSA account for each respective EMS Employee. Except with respect to such
balances established before the Closing Date, nothing in this Section shall
imply that Maxwell or MSD is assuming liabilities for any benefit to an EMS
Employee earned or accrued on or prior to the Closing Date.

                (f)     MSD may, at MSD's expense, conduct any meeting or set up
any interview with any EMS Employee at or prior to the Closing which MSD deems
necessary in effecting the transactions contemplated in this Agreement. The
Company and PPI agree to permit the EMS Employees to participate in such
meetings with MSD during normal business hours while such employees are not on
shift.

                (g)     The Company and PPI agree that as of the Closing Date,
they shall have paid when due to each of the EMS Employees all wages, salary and
other amounts due or owing to such employees from the Company and PPI with
respect to employment up to the Closing Date, and at or prior to the Closing
Date they shall pay to each such employee such additional amounts, mutually
agreed upon by the Company and PPI and such employee, as may be necessary to
fully compensate the employee for all other employment related benefits or
entitlements owing or accrued by such employee through the Closing Date, and not
assumed by MSD, including, without limitation bonuses.

                (h)     Provided MSD hires the EMS Employees as provided herein,
the Company and PPI hereby covenant and agree that they shall be solely
responsible for and shall pay any and all severance pay or other severance
obligations attributable or owing to any employee of PPI terminated by PPI on or
before the Closing Date (whether or not in connection with the transactions
contemplated by this Agreement) and shall have sole responsibility for direct
pay or chargebacks by any governmental agency on account of unemployment
compensation attributable thereto. The parties acknowledge and agree that no
severance obligation arises with respect to any EMS Employee as a result of the
transaction contemplated hereby.

                (i)     Maxwell or MSD shall have the right to enforce each and
every confidentiality or similar agreement in the form attached to Schedule 2.6
signed by an EMS Employee while in the employ of PPI or the Company, provided,
that PPI shall be given notice of any claim MSD or Maxwell may have and shall
have the right for fifteen (15) days



                                        9

after such notice to commence to prosecute such claim on its own or MSD's behalf
and shall thereafter prosecute such claim diligently.

approved by all requisite corporate action on the part of the Company and PPI
and, if necessary, their shareholders. Except for the approval of the Company's
Board of Directors and/or as set forth in Schedule 2.3 hereto, no further
approvals or consents by, or filings with, any federal, state, municipal,
foreign or other court or governmental or administrative body, agency or other
third party is required in connection with the execution and delivery by the
Company and PPI of this Agreement or the consummation by the Company and PPI of
the transactions contemplated hereby, except for those which, if not



                                       12
<PAGE>   20

this Agreement or to consummate the transactions contemplated hereby.

        2.4     No Violations. Except as set forth on Schedule 2.4 attached

default) under, or give rise to any right of termination, cancellation or
acceleration under any of the terms, conditions or provisions of any material
lease, license, promissory note, contract, agreement, mortgage, deed of trust or
other instrument or document to which the Company or PPI is a party or by which
the Company or PPI or any of their respective properties or assets may be bound,
(c) violate any order, writ, injunction, decree, law, statute, rule or
regulation of any court or governmental authority applicable to the Company or
PPI or any of their respective properties or assets or (d) give rise to a

        2.8     Financial Statements. The Company and PPI have delivered to MSD
and Maxwell the detailed financial description of the EMS Business set forth in
Schedule 2.8 attached hereto (the "Financial Statements"). The Financial
Statements were (a) prepared from the books and records kept by PPI and the
Company, and fairly and validly reflect the EMS



                                       15
<PAGE>   23

Group's transactions, (b) have been prepared in accordance with the accounting
principles consistently applied in PPI's standard accounting practices and
procedures, which differ in certain material respects from generally accepted
accounting principles as described on Schedule 2.8 (c) have been used by the
management of PPI in the operation of the EMS Business and to determine the
division contribution of the EMS Business and the San Leandro site expenses for
the periods indicated therein. MSD AND MAXWELL ACKNOWLEDGE THAT THE FINANCIAL
STATEMENTS WERE NOT PREPARED ACCORDING TO GENERALLY ACCEPTED ACCOUNTING
PRINCIPLES, AND HAVE NOT BE INDEPENDENTLY AUDITED. Except as expressly disclosed
in Schedule 2.8 hereto, the Financial Statements (a) present fairly the
financial position and results of operations of the EMS Group as of and for the
periods then ended, (b) disclose all liabilities, including contingent and/or
unmatured liabilities as of the dates thereof, of the EMS Group, (c) fairly
present the assets of the EMS Business, including funded and unfunded backlog,
and (d) reflect that PPI and the EMS Group have set aside to their best
knowledge reserves adequate in all material respects (w) for performance of
Client Contracts (as defined herein), (x) with respect to any DCAA audit, for
all reasonably anticipated audit adjustments, (y) with respect to inventory, for
all inventory reasonably anticipated to have no value and (z) with respect to
warranties, for all reasonably anticipated warranty claims, and each of, (w),
(x), (y) and (z) above has been estimated consistent with the historical
practice of PPI and the EMS Group. Except as set forth on Schedule 2.8, DCAA has
completed audits of the EMS Business through and including the contract year
1994, no material adverse adjustments were required to be made by DCAA as a
result of the last completed audit, and to the best knowledge of the Company and
PPI, when the DCAA completes its audits of all periods prior to the Closing, no
material adverse adjustments will be required to be made as a result thereof.
Nothing in the foregoing representation and warranty is intended as a guarantee
by the Company or PPI of the adequacy of any reserve shown on the Closing
Balance Sheet, and the parties acknowledge and agree that certain issues with
respect to reserves are governed solely by Section 1.4(b) or Section 9.7. The
EMS Group maintains accounting controls sufficient to provide reasonable
assurances that such transactions are, in all material respects, (i) executed in
accordance with management's general or specific authorization, and (ii)
recorded consistent with the policies of the Company and past practices.

        2.9     Accounts Receivable. Schedule 1.1(h) hereto sets forth a
complete, current and correct list of the Accounts Receivable as of March 29,
1998. The Accounts Receivable represent bona fide sales actually made or
services actually performed on or prior to such date in the ordinary course of
the EMS Business and consistent with past practices. Except as set forth on
Schedule 2.9 attached hereto, to the best knowledge of the Company and PPI,
there is no material contest, claim or right of set-off contained in any oral or
written agreement with any account debtor relating to the amount or validity of
any Account Receivable, or any other account receivable created after March 29,
1998 and prior to Closing. The Accounts Receivable (net of any reserves
reflected in the EMS Financials) are valid and are collectible in the ordinary
course of the EMS Business. The write-offs for uncollectible accounts receivable
reflected in the Financial Statements have been established in the ordinary
course of the EMS Business, in accordance with principles consistently applied
for at least three years. For



                                       16
<PAGE>   24

purposes of this Section 2.9, the term "material" shall mean having a value
greater than $10,000.

        2.10    Licenses and Permits. Schedule 2.10 attached hereto contains a
complete, current and correct list of all governmental licenses, permits,
franchises, rights and privileges necessary for the present conduct of the EMS
Business (the "Licenses"). Except as set forth in Schedule 2.10, the EMS Group
possesses all such Licenses. Each of the Licenses is in full force and effect,

<PAGE>   26

(iii) constituting Client Contracts (as defined below); (iv) with Affiliates;
(v) resulting in the creation of any lien or security interest (including lease
notifications) or (vi) otherwise material to the EMS Business. To the best
knowledge of the Company and PPI, other than as set forth on Schedule 2.12(a),
no event has occurred which would constitute a default (or any event which, with
the giving of notice or lapse of time or both, would constitute a default) under
any term or provision of any of the Contracts and thereby allow a party to
thereto terminate and/or claim damages therefor. Each of the Contracts is in
full force and effect and is the legal, valid and binding obligation of the
Company or PPI and, to the best knowledge of the Company and PPI, of the other
parties thereto, enforceable in accordance with its terms, except as may be
limited by bankruptcy, reorganization, insolvency, moratorium, government
contracting or other laws relating to or affecting the enforcement of creditors'
rights and remedies generally and except as enforcement may be limited by
general principles of equity and government sovereignty. Except as set forth on
Schedule 2.12(a), neither the Company nor PPI has received, from a client that
is a party to a Contract (a "Client"), written notice, or explicit oral advice
from a person authorized to terminate or direct others to terminate a Contract
for convenience or materially change its terms, which oral advice was given to a
Key Employee (any such written notice or oral advice being referred to herein as
"Advice"), that such client intends to cancel, terminate or refuse to renew any
such Contract or to exercise or decline to exercise any option or right
thereunder or to reduce or modify their purchases, sales or dealings with
respect to a Contract, and such notice or a description of the Advice is stated
on Schedule 2.12(a). The Company and PPI are not parties to any Contract that
restricts them from carrying on the EMS Business or any part thereof, or from
competing in any line of business with any person, corporation or entity. Prior
to the date hereof, the Company and PPI have provided to MSD a complete, current
and correct copy of each of the written Contracts which MSD requested to review
as shown on Schedule 2.12(c), as well as a written summary of each of the oral
Contracts listed on Schedule 2.12(c), including all amendments and modifications
thereto. EXCEPT AS SPECIFICALLY SET FORTH HEREIN, NEITHER THE COMPANY NOR PPI
MAKE ANY REPRESENTATION OR WARRANTY HEREUNDER CONCERNING ANY OPTION PURSUANT TO
ANY CONTRACT, INCLUDING BUT NOT LIMITED TO ANY INTENTION OF ANY PARTY TO SUCH
CONTRACT TO EXERCISE OR NOT EXERCISE ANY SUCH OPTION. Except as set forth on
Schedule 2.12(a), neither the Company nor PPI has received written notice or
Advice from a Client that a follow-on contract to an existing contract will not
be granted. For purposes of the foregoing sentence, information publicly
available to MSD is excluded.

                (b)     Schedule 2.12(b) attached hereto identifies those
Contracts for work to be performed by the EMS Group that are partially performed
at the Closing Date or on which services have not commenced on the Closing Date
consisting of all Fixed Price Contracts (as defined below) and those cost plus
fixed fee Contracts with a value of $25,000 or more (collectively "Client
Contracts"). Schedule 2.12(b) (i) identifies each Client Contract which is
subject to a maximum cost, a fixed fee or a lump sum ("Fixed Price Client
Contracts"), and (ii) states the estimated percentage of completion for each
Fixed Price Client Contract listed thereon and the estimated costs and expenses
required to complete the Fixed Price Client Contract. The EMS Group has not
granted any time reductions, unbilled services, discounted



                                       19
<PAGE>   27

services or other discounts on the Client Contracts. After the Closing, the
Company and PPI shall cooperate with MSD to secure any amendments to Contracts
shown on Schedule 2.12(b) required to permit MSD to bill the other party to each
Contract shown on Schedule 2.12(b) for all services performed after the Closing
Date on each such Contract at the rates stated in each such Contract.

        2.13    Supplier Relationships. Except as set forth in Schedule 2.13,
neither the Company nor PPI has received any Advice which might reasonably
indicate that any of the current, active subcontractors or suppliers of the EMS
Group intends to cease, selling to or dealing with the EMS Group in the manner
in which such transactions have previously occurred, nor has the Company or PPI
received any Advice which might reasonably lead it to believe that any current,
active subcontractor or supplier of the EMS Group intends to alter in any
respect the amount of such sales or the extent of dealings with the EMS Group or
would alter in any respect any such sales or dealings in the event of the
consummation of the transactions contemplated hereby. The EMS Group is current
and in full compliance with respect to all of its material obligations to its
suppliers and subcontractors.

having jurisdiction over the Company, PPI and the EMS Business, including
without limitation all such laws, regulations, ordinances and requirements
relating to insurance, environmental, antitrust, consumer protection, labor and

Advice of any asserted present or failure within the last five years by the EMS
Group to comply with such laws, statutes, ordinances, rules, regulations, orders
or other requirements, which has had or may have a Material Adverse Effect.

        2.15    No Undisclosed Liabilities. As of December 31, 1997, the EMS
Business has (x) with respect to contracts between the EMS Group and the U.S.
Government, no liabilities of any nature, whether accrued, absolute, contingent

stated or adequately reserved in the Financial Statements or reflected in the
footnotes thereto, or (y) with respect to all Client Contracts, no liabilities
for loss contracts, other than liabilities (i) stated or adequately reserved in
the Financial Statements or reflected in the footnotes thereto, or (ii)

        4.4     Access. MSD may, prior to the Closing Date, through its
employees, agents and representatives (including accountants and attorneys),
make or cause to be made such reasonable investigation as it deems necessary or
advisable of the assets, properties and business of the EMS Group, but such
investigation shall not affect the representations and warranties of the Company
and PPI hereunder or the right of MSD to terminate this Agreement as provided in
Article 10 hereof, except as specifically set forth in Section 5.1. The Company
agrees: (i) (subject to the confidentiality provisions hereof and any reasonable
restrictions imposed by PPI or the Company in light of any agreement with any
customer of PPI and/or applicable law, including but not limited to antitrust
laws and government secrecy laws to the extent deemed applicable or otherwise
restrictive by the Company or PPI at their reasonable sole discretion) to permit
MSD and its employees, agents and representatives to have complete access to the
properties, assets, books and records, environmental reports and records,

data and other information with respect to the



                                       29
<PAGE>   37

EMS Business as MSD shall from time to time reasonably request (including
without limitation true and correct copies of all financial statements of PPI
relating to the EMS Business for all periods within the last five years, and to
authorize the Key Employees and other expressly authorized representatives of
the EMS Group to discuss the affairs of the EMS Business with the employees,
agents and representatives of MSD. MSD's representatives shall also be permitted
to contact the customers and clients of the EMS Group to discuss their
respective businesses, after the customer has been contacted by the responsible
employee of the EMS Group. The Company and PPI will fully cooperate with MSD and
its counsel in connection with any steps reasonably required to be taken as part
of its obligations under this Agreement.

        4.5     Use Of Trademarks. Neither the Company nor PPI shall hereafter
use or register or attempt to use or register any trademark or trade name or

from the Closing, from using the name "Physics International" in its current
business outside of the United States. Following the Closing, PPI shall change
its name to a name that does not include the name "Physics International."

        4.6     Employee Benefits.

                (a)     For purposes of this Agreement: the term "Benefit Plans"
shall mean (i) all employee benefit plans, as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974 ("ERISA"); and (ii) all other

stock bonus, restricted stock, stock appreciation right, vacation pay, holiday
pay, severance, dependent care assistance, excess benefit, incentive, salary
continuation, supplemental retirement, employee loan or loan guarantee program,
and other compensation arrangements; and the term "Primex Benefit Plans" shall
mean Benefit Plans maintained or contributed to by the Company or PPI or their
predecessors in interest with respect to the EMS Group for the benefit of its
employees (or former employees) and/or their beneficiaries.

                (b)     MSD will not adopt any of the Primex Benefit Plans;
rather, the Company and PPI shall retain all liabilities relating in any manner
whatsoever to any Primex Benefit Plan regardless of when the event giving rise
to that liability occurs. For example, PPI shall be responsible for providing
"continuation coverage" to "qualified beneficiaries" with respect to all
"qualifying events" (as those terms are defined in Code Section 4980B) that
occur on or before the Closing.

                (c)     With respect to the Olin pension plan for non-bargaining
unit employees of certain defense operations (the "Olin Plan"), pursuant to
which various EMS Employees are eligible for retirement benefits, PPI will give
notice to the relevant EMS Employees on or prior to April 3, 1998 stating that
Olin has arranged to provide for EMS Employees aged 52 or more with at least
seven years of service to qualify for early retirement benefits under the Olin

of Maxwell or MSD.

retention bonuses to certain Key Employees aged 46 to 51 on the date hereof as
listed on Schedule 4.6(d). Upon receipt of evidence of payment, the Company or
PPI shall reimburse Maxwell and MSD for one-half of the amount paid, up to a
maximum of $151,000.

        4.7     Alteration of Facility. If and to the extent Merced Associates
or any subsequent landlord under the Facility Lease, requires, pursuant to
paragraphs 14 and 15 of the Facility Lease, restoration of the premises to its
original condition or any other past condition for any alterations made prior to
the Closing Date or made pursuant to the OTS Sublease as part of Sublessee's
work thereunder, then the Company and PPI shall be jointly and severally liable
to Maxwell and MSD for the reasonable cost of such work. Maxwell, at its sole
option, may elect either to perform the work and seek reimbursements, or to
require the Company and PPI to perform such work at their sole cost and expense.
This covenant shall survive (i) any extension of the lease term; and (ii) any
assignment of the Facility Lease or Ground Sublease by MSD or Maxwell. The
Company and PPI understand and acknowledge that the foregoing is a material
inducement to Maxwell and MSD to enter into this Agreement.

party shall promptly disclose such fact or omission to all other parties hereto.
In the event that the discovering party proceeds with signing this Agreement
and/or a Closing despite actual knowledge of any such fact or omission, for
purposes of indemnification hereunder under Article IX (unless the indemnity
relates to liabilities not assumed by a party) and for all other purposes, such
actual knowledge shall result in a waiver of the applicable breach of this
Agreement.

        5.2     Facility and Support Costs. In connection with the San Leandro
operations, prior to the Closing PPI and MSD shall execute the Transition
Services Agreement setting forth a method of allocating expenses shared by the

prior written consent of all other parties hereto unless



                                       31

Date and ending five years from the date of Closing, neither the Company nor

with Maxwell or MSD in the EMS Business or any substantially identical business
in the United States or elsewhere in the world. For the same five year period,

forms a material part of the consideration provided to Maxwell and MSD for their
entry into this Agreement, and each and every successor to the business of the
Company or PPI shall comply with this covenant.

exercised by PPI with respect to its business records prior to the Closing, (ii)
not dispose of any Record earlier than the time period stated in clause (i)
without first giving PPI and the Company at least three months advance written
notice of such destruction and obtaining PPI's written consent thereto, and

liabilities, fines, penalties, damage, injunctive relief, injuries to person,
property or natural resources, cost, expense, including without limitation

location of the EMS Business or the OTS Business (whether or not the Site) on or
before the Closing Date whether known or unknown, fixed or contingent,
foreseeable or unforeseeable, regardless of the source of such release, or when
such presence is discovered, and any violation or noncompliance with Hazardous
Materials Law by the Company or PPI, provided that: (i) the act, event,
circumstance or omission forming the basis of such claim occurred on or before
the Closing Date, (ii) changes in existing Federal, State and local Hazardous
Materials Law and/or enactment of new laws or new interpretation of

all remedies available to them, if any, by means of an action against any third
party responsible or otherwise liable for the loss, including but not limited,
to the U.S. Government and/or any insurance company (provided, however, that the
expense incurred and not recovered in any action against a governmental or other
third party shall be included within the Indemnified Matters, and, provided
further, that any delay caused by asserting a claim against a governmental or
other third party shall extend the periods described in Section 9.4(b) below
during the time such action is prosecuted); and (v) the presence of Hazardous
Materials at any location or former location of the EMS Business shall only
constitute an Indemnified Matter after such times as



                                       38
<PAGE>   46

and to the extent MSD is required by applicable Hazardous Materials Law to
report such presence to regulatory authorities, in which event MSD will use
reasonable best efforts to give PPI notice of a claim under this Section prior
to making such a report.

        The foregoing indemnity includes, without limitation, all reasonable
costs in law or in equity of investigation, assessment, containment, removal,

the MSD Indemnitees' reasonable attorneys' and consultants' fees and all court
costs.

                (b)     Notwithstanding the foregoing, for any claims for
indemnification under this Section 9.4, made after March 31, 2008, the Company
and PPI's obligation shall be limited such that, if a claim is made after March
31, 2008, the Company's and PPI's share of the losses, costs, and expenses
(including but not limited to remediation expense) constituting Indemnified
Matters and the amount of the MSD Indemnitees' recovery from the Company and PPI
shall be limited to the percentage shown in the table below:

        After March 31, 2011 and before April 1, 2012    20% of Indemnified Matters
</TABLE>

No further claims for indemnification shall be made under this Section after
April 1, 2012. Any claims made prior to that time shall be subject to
indemnification (with all applicable limits) under this Section regardless of
when any disputes with respect thereto, or ongoing remediation or monitoring, is
concluded. For claims in which the Company's and PPI's liability is limited to
40% or less of the Indemnified Matters (and in which no third party suit is
brought directly against the Company and/or PPI), MSD shall control all
litigation and remediation with respect to such matters, notwithstanding that
Maxwell or MSD may be an "Indemnitee" under Section 9.11. For all other claims,
the Company or PPI shall control all litigation and remediation with respect to
such matters pursuant to the terms of Section 9.11. Nothing in Section 9.4(b)
shall be construed as implying that Maxwell or MSD has assumed any liability for
any environmental matters as set forth in Section 1.6(j) hereof.

                (c)     Maxwell and MSD jointly and severally hereby agree, to
indemnify, defend, protect, and hold the Company and PPI harmless from and
against, and shall reimburse them for, any and all losses, claims, liabilities,
fines, penalties, damage, injunctive relief, injuries to person, property or
natural resources, cost, expense, including without limitation reasonable
attorneys' and experts' fees, action or cause of action (collectively, the



                                       39
<PAGE>   47

"Indemnified Matters"), arising in connection with the release of any Hazardous
Substance after the Closing Date at the San Leandro Site or any other location
of the EMS Business established by MSD after Closing whether known or unknown,
fixed or contingent, foreseeable or unforeseeable, regardless (except as set
forth below) of the source of such release, or when such presence is discovered,
and any violation or noncompliance with Hazardous Materials Law by Maxwell or
MSD, provided, Maxwell and MSD shall not be responsible for any release or
discharge of Hazardous Substances by the OTS Business. This indemnification
terminates April 1, 2012. In their capacity as a sublessee at the Facility, a
Landlord at the Facility or in carrying out its obligations under Section 9.11,
the Company and PPI and their agents and representatives shall cooperate, to the
fullest extent possible, with any litigation undertaken, prosecuted or defended
against by Maxwell and MSD (including defenses of Third Party Claims tendered
under Section 9.11), or any remediation at the location of the EMS Business that
does not unreasonably disrupt the normal performance of the OTS Business; (iv)
prior to exercising its rights to an indemnity pursuant to this Section, the
Company and PPI shall first use reasonable best efforts to exhaust all remedies
available to them, if any, by means of an action against any third party
responsible or otherwise liable for the loss, including but not limited, to the
U.S. Government and/or any insurance company (provided, however, that the
expense incurred and not recovered in any action against a governmental or other
third party shall be included within the Indemnified Matters, and, provided
further, that any delay caused by asserting a claim against a governmental or
other third party shall extend the expiration of this indemnity during the time
such action is prosecuted); and (v) the presence of Hazardous Materials at any
site or future location of the EMS Business shall only constitute an Indemnified
Matter after such times as and to the extent the Company or PPI is required by
applicable Hazardous Materials Law to report such presence to regulatory
authorities, in which event the Company or PPI will use reasonable best efforts
to give MSD notice of a claim under this Section prior to making such a report.

                (d)     Post-Closing Investigations. Except to the extent
required by a governmental agency, after the Closing Date, MSD and Maxwell shall
not perform or cause to be performed any work, investigations or inspections at,
in, on, or under the Site including but not limited to intrusive testing or soil
sampling ("Post-Closing Investigations"), unless MSD or Maxwell shall have
obtained the prior written consent of PPI, which consent may be withheld in
PPI's sole discretion, unless Maxwell or MSD is otherwise required to perform
such Post-Closing Investigation by the Hazardous Materials Laws, or in
connection with any sale of or financing of the EMS Business (provided MSD and
Maxwell shall in good faith use their reasonable best efforts to minimize the
necessity, degree and/or scope of any Post- Closing Investigation in connection
with any such sale or financing). MSD and Maxwell, at their sole cost and
expense, and to the fullest extent permitted by law, hereby agree to and shall
indemnify, defend, protect and hold harmless the Company and PPI, from and
against any and all loss, damage, cause of action, cost, claim, expense,
mechanic's lien, materialmen's lien and any liability of any kind whatsoever,
including, without limitation, reasonable attorney's fees, incurred by the
Company or PPI in connection with or arising out of any such Post-Closing
Investigations not permitted by this subsection (c). Further, notwithstanding
any provision in this Section 9.4 to the contrary, Maxwell's or MSD's



                                       40
<PAGE>   48

violation of the provisions of this subsection (c) shall nullify all of the
Company's and PPI's obligations to indemnify the MSD Indemnitees pursuant to
subsection (a). Should PPI consent to Post-Closing Investigations and MSD
conducts the same, MSD shall promptly provide PPI with a copy of any report
("Investigation Report") generated pursuant thereto which document the methods,
processes, findings and conclusions related to the Post-Closing Investigations.

                (e)     The indemnities under this Section 9.4 shall not be
subject to the Company Cap or the Maxwell Cap (as defined in Section 9.10), but
is subject to the MSD Threshold and the Company Threshold (as defined in Section
9.10).

        9.5     Indemnity by MSD and Maxwell. MSD and Maxwell shall jointly and
severally indemnify, hold harmless, defend and protect the Company and PPI from
and against, and shall jointly and severally reimburse the Company and PPI on
demand for any loss, liability, damage or expense that the Company and/or PPI
shall incur or suffer (collectively, the "Company's Recoverable Losses") arising
out of or resulting from any misrepresentation or breach by MSD and/or Maxwell
or of any (i) representation or warranty contained in Article 3 hereof (and, to
the extent incorporated therein, in any certificate, exhibit or schedule
delivered by or on behalf of Maxwell or MSD pursuant hereto not waived by the
Company or PPI as provided in Section 5.1 hereof), (ii) agreement or covenant
under or pursuant to this Agreement, or (iii) any Assumed Liability or other
liability, obligation (or portion thereof) or commitment expressly assumed or
undertaken by MSD and/or Maxwell under this Agreement notwithstanding the terms
of any novation, assignment or subcontract entered into between MSD and PPI upon
or following the Closing (collectively with respect to which a claim for the
Company's Recoverable Losses is made by the Company and PPI hereinafter referred
to as a "MSD Purchase Agreement Breach"), or from any liability of the EMS Group
arising in any way out of facts and circumstances occurring after the Closing
Date, including but not limited to the operation of the EMS Business and the use
of the Purchased Assets (except to the extent, and only to the extent, such
liability gives rise to an indemnification obligation on the part of the Company
and PPI for which specific provision is made herein).

        9.6     Indemnification for Employee Matters (Post-Closing). Maxwell and
MSD, jointly and severally, agree to defend, indemnify and hold harmless the
Company from any and all liability, including without limitation all attorneys'
fees and costs, incurred by the Company and/or PPI in connection with this
Agreement and the transactions contemplated hereby to the extent arising out of:
(i) the employment or termination of any EMS Employee by MSD at any time
following Closing, or (ii) out of any employee benefit plan maintained by
Maxwell or MSD or to which Maxwell or MSD contributes after the Closing on
behalf of any EMS Employee. The indemnification provided for by this Section 9.9
shall not be subject to the limitations set forth in Section 9.10.

        9.7     Indemnification for Accounts Receivable.

                (a)     One year after the Closing Date, MSD shall determine the
aggregate amount of Accounts Receivable which have not been paid and are deemed
by MSD as



                                       41
<PAGE>   49

uncollectible (the "Unpaid Accounts Receivable"). MSD shall send to the Company
and PPI a written notice showing the Unpaid Accounts Receivable, and the Company
and PPI shall pay to MSD such Unpaid Accounts Receivable. Unless PPI or the
Company object in writing within thirty (30) days of receipt of such notice,
such payment shall be made within thirty (30) days of the receipt of such
notice. Upon such payment by the Company and PPI, all of MSD's and Maxwell's
right, title and interest in such Unpaid Accounts Receivable shall be assigned
by MSD and Maxwell to the Company and PPI. To the extent the Company and PPI are
required to make any payment to MSD with respect to Unpaid Accounts Receivable
and any additional amounts shall have been received by MSD or Maxwell from
obligors on the Accounts Receivable, MSD and Maxwell shall promptly refund to
the Company and PPI such payment. The indemnification provided for by this
Section 9.7 shall not be subject to the limitations set forth in Section 9.10.

                (b)     If MSD and Maxwell, on the one hand and the Company and
PPI on the other hand, are unable to determine jointly which Accounts Receivable
have not actually been paid to MSD, the Company and PPI shall within three (3)
business days thereafter jointly submit their dispute to the Arbitrator.

        9.8     Indemnity for Defective Pricing.

                (a)     From and after the Closing Date, to the extent that MSD
is required to pay and pays any amounts to third parties in respect of
liabilities for defective pricing of Contracts with a government agency as a
party due solely to actions or omissions occurring on or prior to the Closing
(the "Reimbursable Liabilities"), MSD shall send to the Company and PPI a
written notice showing the amounts of such Reimbursable Liabilities paid by MSD,
and the Company and PPI shall (unless they reasonably dispute such amounts)
reimburse MSD for such payments, within thirty (30) days of the receipt of such
notice. The indemnification set forth in this Section 9.8 shall not be subject
to the limitations set forth in Section 9.10.

                (b)     If MSD and the Company and PPI are unable to determine
jointly which Reimbursable Liabilities have been paid by MSD, MSD and the
Company and PPI shall within three (3) business days thereafter jointly submit
their dispute to the Arbitrator.

        9.9     Indemnity for Employee Matters (Pre-Closing). The Company and

and all liability, from all MSD Recoverable Losses to the extent arising out of:

        9.10    Limitations on Recoverable Losses.

                (a)     Claims Against the Company and PPI. Claims for payment
of MSD's Recoverable Losses in respect of a Company Purchase Agreement Breach
(other than claims for payment under Sections 9.2(B), (C) or (D), 9.4, 9.7, 9.8
and 9.9 (except that clause (iii) shall apply to Section 9.4) (i) may be made
only with respect to claims arising during the General Liability Period, (ii)
must be made, if at all, by giving the written Claim Notice (as defined in
Section 9.11(a) hereof) to the Company during the General Liability Period, as
applicable, with respect to such claim, (iii) may be made only to the extent
that the aggregate amount of MSD's Recoverable Losses shall exceed $100,000 (the
"MSD Threshold"); provided that once the MSD Threshold is reached all such
claims, including those comprising the Threshold, may be made and shall be paid;
and (iv) shall not exceed $7.5 million in the aggregate (the "Company Cap").

                (b)     Claims Against Maxwell and MSD. Notwithstanding anything
to the contrary, express or implied, set forth herein, claims for payment of the
Company's Recoverable Losses in respect of a MSD Purchase Agreement Breach

be made only with respect to claims arising during the General Liability Period,
(ii) must be made, if at all, by giving a written Claim Notice to MSD during the
General Liability Period with respect to such claim; and (iii) may be made only
to the extent that the aggregate amount of the Company's Recoverable Losses

Threshold is reached all such claims, including those comprising the Threshold,
may be made and shall be paid; and (iv) shall not exceed $7.5 million in the
aggregate (the "Maxwell Cap").

        9.11    Claims for Indemnification; Disputes.

                (a)     Claims for Indemnification. Any party hereto
(individually or with others, collectively, the "Indemnitee") shall give the
Company and PPI, or MSD and Maxwell, as the case may be (the "Indemnitor"),
written notice (the "Claim Notice") of any claim (including the receipt of any
demand) or the commencement of any action with respect to which indemnity may be
sought by the Indemnitee (individually, a "Claim" and collectively, the
"Claims"); provided, however, that if the Indemnitee fails to give such Claim
Notice in a materially correct form prior to the expiration of the General
Liability Period or other applicable period, all rights of the Indemnitee to
assert any such Claims for a MSD Purchase Agreement Breach or the Company
Purchase Agreement Breach, as the case may be, shall terminate and be forever
waived. The Claim Notice shall state (i) the aggregate amount of MSD's
Recoverable Losses or the Company's Recoverable Losses (in either case,
"Recoverable Losses") as to which indemnification is being sought (which amount
may be estimated and updated from time to time, and which shall, in the case of
MSD Recoverable Losses, describe such amount both gross and net of the Tax
benefit to MSD); (ii) the components of the amount of Recoverable Losses for
which indemnification is being sought (which components may be estimated and
updated from time to time); and (iii) a general



                                       43
<PAGE>   51

description of the grounds upon which the Claim for indemnification is being
made. The right of the Indemnitee to indemnification for a Claim shall be deemed
to be accepted by the Indemnitor unless, within 30 days after the Indemnitor's
receipt of the Claim Notice, the Indemnitor shall notify the Indemnitee in
writing that it objects to the right of the Indemnitee to indemnification with
respect to the Claim.

                (b)     Control of Litigation; Mutual Cooperation. If a Claim is
based upon a claim asserted by a third party against the Indemnitee (a "Third
Party Claim") and the Indemnitor refuses tender of the defense of such claim or
otherwise denies liability for the Claim, the Indemnitee shall be entitled to
control the defense of the Third Party Claim, including, without limitation, the
employment of counsel and the right to settle the Third Party Claim without any
participation by or consent from the Indemnitor. All fees and expenses of
counsel retained by the Indemnitee to defend such Third Party Claim, expert
witness fees and other costs incurred in such action, shall be payable by the
Indemnitee defending such Third Party Claim; provided, however, that if such
Third Party Claim results in a Recoverable Loss for which the Indemnitor,
notwithstanding any denial of liability, is found to be liable hereunder, such
reasonable fees and expenses of counsel, expert witness fees and other
reasonable costs incurred in such action shall be deemed to be included in such
Recoverable Loss and payable by the Indemnitor to the extent and under the
limitations provided in this Article 9. If the Indemnitor does not deny
liability for the Claim hereunder, the Indemnitor shall be entitled, in his or
its discretion, to assume the defense of the Third Party Claim, including,
without limitation, the employment of counsel reasonably satisfactory to the
Indemnitee. If the Indemnitor does not deny liability for the Claim hereunder,
but does not elect to assume the defense of the Third Party Claim, the
Indemnitee shall be entitled to assume the defense of the Third Party Claim.
Regardless of which party is controlling the defense of the Third Party Claim
for which the Indemnitor admits liability hereunder, (i) the Indemnitor and the
Indemnitee shall act in good faith; (ii) no settlement of the Third Party Claim
may be agreed to without the written consents of the Indemnitor and the
Indemnitee, which consents shall not be unreasonably withheld; (iii) the
reasonable fees and expenses of counsel retained to defend the Third Party
Claim, expert witness fees and other costs incurred in such action shall be
deemed to be included in such Recoverable Losses and shall be payable by the
Indemnitor to the extent and under the limitations provided in this Article 9;
and (iv) the party controlling the defense of the Third Party Claim shall
deliver, or cause to be delivered, to the other party copies of all
correspondence, pleading, motions, briefs, appeals or other written statements
relating to or submitted in connection with the defense of the Third Party
Claim, and timely notices of, and the right to participate in (as an observer),
any hearing or other court proceeding relating to the Third Party Claim.

                (c)     Resolution of Disputes. The Indemnitor and the
Indemnitee shall undertake in good faith to or to have their representatives
promptly meet and attempt to resolve all disputes regarding indemnification. If
the Indemnitor and the Indemnitee are unable to resolve any such dispute within
twenty (20) days, then any party may submit the dispute to arbitration in
accordance with the following:



                                       44
<PAGE>   52

                        (i)     Arbitration shall be conducted under the
supervision of and in accordance with the Commercial Arbitration Rules of the
American Arbitration Association ("AAA").

                        (ii)    The parties will use their best efforts to agree
upon a mutually acceptable arbitrator within twenty (20) days after submission
of the dispute to arbitration. If the parties are unable to agree upon a
mutually acceptable arbitrator, then any party may request the AAA to supply a
list of potential arbitrators satisfying the requirements of any paragraph below
and such other requirements as the parties may agree upon. Within ten (10) days
after receipt of the list, the Company and PPI, on the one hand, and MSD and
Maxwell, on the other hand, will independently rank the proposed arbitrators,
simultaneously exchange rankings, and select as the arbitrator the individual
receiving the highest combined ranking who is available to serve.

                        (iii)   Any arbitrator under this Section 9.11(c) will
be impartial in fact and appearance, not an advocate of any party. The
arbitrator will not have: (x) any direct or indirect financial or personal
interest in the outcome of the mediation or arbitration; or (y) any past,
present or anticipated financial, business, professional, family, social or
other relationship which is likely to affect impartiality or which might
reasonably create the appearance of partiality or bias. Any arbitrator under
this Section 9.11(c) will be required to disclose to each of the parties any
such interest or relationship, and the parties may agree to waive the
requirements of the preceding sentence as to any interest or relationship so
disclosed.

                        (iv)    Unless otherwise agreed by the parties, any
arbitration under this Section 9.11(c) will be held in San Francisco, California
at a location selected by the arbitrator.

                        (v)     The arbitrator will render his or her decision
in writing not later than thirty (30) days after the final statements and proof
have been submitted and any hearing on the matter is closed. The decision of the
arbitrator will be conclusive and binding upon the parties and judgment on the
award may be entered in any court of competent jurisdiction or application may
be made to such court for judicial acceptance of the award and an order of
enforcement, as the case may be; provided, however, that the arbitrator's
decision will be subject to judicial review, and the reviewing court may vacate,
modify or correct the arbitrator's decision as appropriate, only in a case (x)
where the arbitrator's findings of fact are not supported by substantial
evidence, (y) where the arbitrator's conclusions of law are erroneous or (z) as
otherwise provided by applicable law.

                        (vi)    In connection with any arbitration under this
Section 9.11(c), costs of the arbitrator, AAA, court reporter, hearing rooms and
other common costs will be divided equally between the Company and PPI, on the
one hand, and MSD and Maxwell, on the other hand. Each party will bear the cost
and expense of preparing and presenting its own case (including, but not limited
to, its own attorneys' fees and costs of witnesses); provided,



                                       45

that the arbitrator shall require, as part of his or her decision, reimbursement
of all or a portion of the prevailing parties' costs and expenses (including,
without limitation, reasonable experts and attorneys' fees) by the other
parties.

                        (vii)   Disputes with respect to the Closing Balance
Sheet shall be governed by the specific provisions of Section 1.5 hereof.

        9.12    Exclusive Remedy. Each party hereto acknowledges and agrees
that, from and after the Closing Date, its sole and exclusive remedy with
respect to any and all claims relating to the subject matter of this Agreement
shall be pursuant to the indemnification provisions set forth in this Article
IX, except that nothing in this Agreement shall be deemed to constitute a waiver
of any tort claims of, or causes of action arising from, fraudulent
misrepresentation or deceit, or to limit the availability of any equitable
remedy to a party.

however, that the parties shall remain obligated for any breach of this
Agreement.

<PAGE>   56

hereof, and any such invalidity or unenforceability in any jurisdiction shall

construed by the appropriate judicial body by limiting or reducing it to the
minimum extent necessary to make it legally enforceable.

        11.7    Governing Law. This Agreement shall be construed and enforced in

other relief to which it may be entitled.

        11.10   Interpretation. As used anywhere in this Agreement, any
representation or warranty given to the knowledge of a party shall mean to the

and a party's "actual knowledge" shall refer to the actual knowledge of such
persons.

        11.11   Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original but all of which shall

interpretation of this Agreement.

        11.17   Updating of Schedules. Each Schedule referred to in Sections 1.1
or 1.6 hereof shall be delivered three days prior to Closing, reflecting in all
material respects the assets and liabilities to be transferred at Closing.
Schedule 11.17 sets forth all Client Contracts for which no consents or
novations have been received in order to effect an assignment and assumption,
and which therefore shall be subject to the Master Subcontract. From time to
time after the Closing Date (in intervals of no less than 30 days), as consents
to assignments or novations are received, PPI shall deliver to MSD updated
Schedules 1.6(b) and Schedules 11.17, together with an assignment and assumption
agreement substantially in the form of Exhibit B, until all Client Contracts
have been duly assigned to MSD and are reflected on the final Schedule 1.6(b).

                 MAXWELL TECHNOLOGIES TO ACQUIRE UNIT OF PRIMEX
              PHYSICS INTERNATIONAL; SOLIDIFIES GLOBAL LEADERSHIP
                           IN PULSED POWER TECHNOLOGY


                                  -----------


          APRIL 2, 1998, SAN DIEGO, CA ... MAXWELL TECHNOLOGIES, INC.
(NMS-MXWL) announced today that it has agreed to acquire the electromagnetic
systems business of Primex Physics International Co., a subsidiary of Primex
Technologies, Inc. (NMS-PRMX), for $10 million in cash. The acquired business'
1997 sales were approximately $17 million. The sale, which is contingent on
obtaining certain approvals, is expected to be concluded by the end of April.

          "Maxwell Technologies and Physics International are two of the world
leaders in the arena of pulsed power technology and this consolidation yields a
technology powerhouse in this domain," said Kenneth F. Potashner, chairman and
chief executive officer of Maxwell.

          "The addition of more than 100 world-class scientists, engineers and
technicians of Physics International clearly makes Maxwell Technologies the
global leader in high-energy pulsed power technology. Our two companies have
responded to Department of Defense and Department of Energy pulsed power and
simulation business requirements for many years and we can now put our
resources to use more effectively and efficiently.

          "Physics International's electromagnetic business also brings to
Maxwell several innovative applications of pulsed power in varying stages of
development with exciting commercial market potential. Among these are a flash
x-ray system for use in ultra-high-speed non-destructive inspection,
complementary technologies for use in food and water purification, a
pulsed-corona device for reducing air pollutants, and a pulsed electrical
energy system for separating valuable minerals from mined rock."

[MAXWELL LOGO]

          Added Walter Robertson, president and general manager of Maxwell
Technologies Systems Division, Inc.: "The acquisition of Physics
International's electromagnetic business greatly expands the resources
available to us and increases the division's annual revenues to close to $50
million. We believe that the larger critical mass resulting from the
acquisition will enhance our bidding prospects for new programs requiring
leading-edge pulsed power solutions."

          Maxwell Technologies is a leader in pulsed power technologies,
providing pulsed power based systems and components for a wide range of
commercial applications and research and development for both commercial
customers and the U.S. government. The Company's advanced technology solutions
address diverse markets such as utilities, telecommunications, medical
equipment and products, food processing and packaging and transportation. The
Company also offers industrial computers and subsystems, primarily to OEMs in
computer telephony and other markets, and software products and services, both
for government research and for various commercial applications.

          Except for historical information contained herein, the matters
discussed in this news release are forward-looking statements that involve
risks and uncertainties, including funding levels for defense and energy
programs, product development based on new technologies, applications and
acceptance of new products in major markets, the impact of competitive products
and pricing, the successful integration of acquired businesses, and other risks
detailed from time-to-time in the Company's SEC reports, including the report
on Form 10-K for year ended July 31, 1997.

          Actual results may differ materially from those projected. These
forward-looking statements represent the Company's judgment as of the date of
this release. The Company disclaims, however, any intent or obligation to
update these forward-looking statements.
