corporation ("CERPLEX Parent") to engage in the business of providing electronic
component manufacturing and repair operations and management, warehouse and
shipping operations and management and related services.  CERPLEX and
SPECTRADYNE believe that, by CERPLEX performing such services for SPECTRADYNE,
CERPLEX will be able to provide such services to SPECTRADYNE at a lower cost
than that which SPECTRADYNE is currently incurring, while CERPLEX will profit on
the performance of its services hereunder.

     B.  CERPLEX desires to provide to SPECTRADYNE, and SPECTRADYNE desires to
obtain from CERPLEX, the repair of electronic components and the operations and
management of the repair facility, warehouse and shipping operations and
management and related services which SPECTRADYNE currently performs at the
SPECTRADYNE Facilities, as defined below.

     C.  In order to enable CERPLEX to provide such services from and after the
Commencement Date, SPECTRADYNE desires to make available to CERPLEX and CERPLEX
desires to use, sublease and/or purchase, on the terms and conditions set forth
in this Agreement, certain resources used by SPECTRADYNE to provide the
services.  In addition, CERPLEX desires to hire certain of SPECTRADYNE's
employees.

     D.  Concurrently with the execution of this Agreement, the parties are
entering into that certain lease as defined in Section 4.1 setting forth the
terms and conditions upon which CERPLEX will lease space from SPECTRADYNE.

     Therefore, the parties agree as follows:

     3.8  DISCLAIMER OF WARRANTIES.  EXCEPT AS SPECIFICALLY SET FORTH IN
SECTION 3.6, CERPLEX DISCLAIMS ALL COMMERCIAL WARRANTIES, EXPRESS OR IMPLIED,
INCLUDING, WITHOUT LIMITATION,  THE WARRANTIES OF MERCHANTABILITY AND FITNESS

provide such new product, "proto-build" services, or other service if
SPECTRADYNE is able to procure such product or service at any equal or higher
level of service from any other source on more favorable terms and conditions,
or either.

     3.11  NON-COMPETITION.  Due to CERPLEX's access to SPECTRADYNE's trade
secrets and intellectual property during the term of this Agreement and the
actual and irreparable damage to SPECTRADYNE that a disclosure of such
confidential information will cause, neither CERPLEX nor any of its
subcontractors (including without limitation subcontractors that are affiliates
and subsidiaries of CERPLEX and the CERPLEX Parent) ("CERPLEX Entity") during
the Term of this Agreement shall directly or indirectly contract with any person
that at the time such contract is entered into competes with SPECTRADYNE in the
provision of in-room video entertainment or interactive services, provided, that
if such person thereafter competes with SPECTRADYNE then any CERPLEX Entity with
whom such person has a contract will, at the request of

                                       9

 
SPECTRADYNE, neither extend or renew its contract with such person beyond the
term existing when SPECTRADYNE makes its request.  If CERPLEX obtains actual
knowledge that an affiliate or subsidiary of CERPLEX or the CERPLEX Parent that
is not a subcontractor of CERPLEX under this Agreement has directly or
indirectly contracted with any person that competes with SPECTRADYNE in the
provision of in-room video entertainment or interactive services, CERPLEX shall
promptly give SPECTRADYNE notice of such contract.  Subject to the foregoing, to
its obligations to supply SPECTRADYNE in accordance with SPECTRADYNE's purchase
orders, and to its obligation to refrain from manufacturing or using SPECTRADYNE
Products for the benefit of anyone other than SPECTRADYNE, CERPLEX may
manufacture any other products for any other person.

Initial Warehouse Space and the cost of such warehousing services shall be
included in the price for SPECTRADYNE Products charged pursuant to Article 8 of
this Agreement and in any price quoted by CERPLEX for any New SPECTRADYNE
Product.  CERPLEX may separately charge for the cost of warehousing services,
and pass through to SPECTRADYNE without mark-up the cost of warehouse and
storage space, for any warehouse space in excess of the Initial Warehouse Space.

          3.12.2  LOCATION OF STORAGE.  CERPLEX's warehousing, inventory
management, and storage services as set forth above shall be carried out
initially at SPECTRADYNE's existing warehouse facilities and at such other
warehouse facilities as CERPLEX may determine.  SPECTRADYNE shall arrange for
CERPLEX to have the use of SPECTRADYNE's existing off-site warehouse facilities.
SPECTRADYNE and CERPLEX shall consult with each other to determine if it is
advisable to sublease or assign SPECTRADYNE's existing off-site warehouse

warehouse space and to the inventory records maintained by CERPLEX.  SPECTRADYNE
shall have the right, at its expense, to audit the inventory and warehouse
records of CERPLEX periodically.

          3.12.4  SHRINKAGE.  Upon the termination or expiration of this
Agreement and upon each Anniversary Date, CERPLEX shall conduct an inventory of
the products as to which CERPLEX is providing warehousing services.  SPECTRADYNE
may participate in such inventory to the extent SPECTRADYNE deems appropriate.
To the extent that CERPLEX through its records is unable to account for the
inventory of the products as to which CERPLEX is providing warehousing services
less 0.5% in dollar amount for shrinkage, then CERPLEX shall, at its option,
either procure replacements for SPECTRADYNE or pay to SPECTRADYNE an amount
equal to the fair market value of such unaccounted-for inventory in excess of
such shrinkage allowance.

     3.13 MANUFACTURING SUPPORT.  CERPLEX acknowledges that manufacturing
engineering and production engineering support are an integral and essential
part of the current processes associated with the manufacture of SPECTRADYNE
Products.  CERPLEX will provide such manufacturing engineering and production
engineering support services during the 12 months following the Commencement
Date at a level that is at least substantially similar to that which has
historically been required to manufacture SPECTRADYME Products during the 12-
month period preceding the Closing Date at no additional cost to SPECTRADYNE.
After said 12-month period, CERPLEX shall provide at no additional cost to
SPECTRADYNE on an ongoing basis that level of manufacturing engineering and
production engineering support as is customarily provided to customers by
contract manufacturers.

     5.2  PERSONNEL.

          5.2.1 TRANSFER OF PERSONNEL.  SPECTRADYNE shall make available to
CERPLEX for job interviews all manufacturing and repair employees (including
managers) of SPECTRADYNE.  CERPLEX shall interview and make conditional offers
of employment to all of the employees listed on Schedule 5.2 (the "Employees").
Before accepting such conditional offer of employment each Employee, shall be
required to resign his/her employment with SPECTRADYNE.  SPECTRADYNE shall be
responsible for any costs, such as all vested and accrued costs for vacation,
pensions, and other employee benefits payable to such Employees in connection
with their resignation.  The Employees who accept job offers shall commence
employment (conditioned on meeting post-offer conditions) with CERPLEX on the
Commencement Date (the "Start Date").  CERPLEX shall be liable for any and all
costs associated with such Employees from and after the Start Date.  For one (1)
year after the Start Date, CERPLEX shall not, without SPECTRADYNE's consent,
employ any person who was a manufacturing and repair employee of SPECTRADYNE and
who was not given or who did not accept an offer of employment from CERPLEX
prior to the Start Date.

          5.2.2 EMPLOYEE PLANS. There have been no prohibited transactions
or other breaches or violations of any law applicable to the Employee Plans that
would subject CERPLEX to any liability. No condition exists that will subject
CERPLEX or any of its employees to any material excise tax, penalty tax,

                                       12

 
fine or any other material liability related to any Employee Plan.  There are no
agreements which will provide payments to any officer, employee, shareholder or
highly compensated individual which will be "parachute payments", under Section
28OG of the Code subject to tax under Section 4999 of the Code for which CERPLEX
would have any withholding liability.

          5.2.3 WORKER ADJUSTMENT AND RETRAINING NOTIFICATION ACT. Both before
and after the Commencement Date, CERPLEX and SPECTRADYNE shall cooperate with
each other to meet all requirements of the worker Adjustment and Retraining
Notification Act, 20 U.S.C. (S)(S) 2101-09.

          5.2.4 NO HIRING OF OTHER PARTY'S EMPLOYEES. The parties agree
that during the Term of this Agreement and for six (6) months after the
termination or expiration of this Agreement neither party nor any of such
party's Affiliates will solicit, without the prior written consent of the other
party, any person employed then or within the preceding twelve (12) months by
such other party or such other party's Affiliates, except that in the event this
Agreement is terminated pursuant to Section 11.1 hereof, this provision shall
not apply to the non-breaching party.

     5.3  DATA PROCESSING SUPPORT.

     SPECTRADYNE shall continue at its expense to operate its systems and
data processing support services as currently operated in support of the
existing manufacturing operations as may be necessary to assist CERPLEX in
performing the Services under this Agreement for a period up to six (6) months
after the date of this Agreement or until CERPLEX completes installation of its
own systems and data processing support services.

          6.1.1 APPOINTMENT AND DUTIES.  CERPLEX and SPECTRADYNE shall each
appoint an individual (and one deputy to serve in the case of such individuals
absence) with overall responsibility for monitoring CERPLEX's performance of
Services and addressing any performance deficiencies under this Agreement (the
"Designated Representatives").  Subject to and in accordance with the terms and
requirements of this Agreement, the Designated Representatives (or their
deputies if a Designated Representative is absent) shall meet upon the request
of either party but at least monthly, to:

                                       13

performance standards by which the services shall be measured and managed as
provided herein;

               (iv) serve as the principal interface between SPECTRADYNE and
CERPLEX with respect to all issues relating to the Services;

               (v) review SPECTRADYNE responsibilities and any failure by
SPECTRADYNE to conform therewith;

               (vi) discuss rate and pricing issues;

               (vii)  discuss and effect any other program management matter
that may arise from time to time; and

               (viii)  attempt to resolve any disputes hereunder in accordance
with Article 13 hereof.

     6.2  SERVICE MODIFICATIONS.  In the event that SPECTRADYNE wishes to
request modifications in the Services, including additions, deletions and
rearrangements ("Service Modifications"), SPECTRADYNE shall submit such requests
to CERPLEX in writing.  CERPLEX will promptly provide SPECTRADYNE with good
faith estimates of the cost, if any, to SPECTRADYNE of such Service
Modifications and will advise as to the most cost effective, efficient means of
implementing such requested Service Modifications (the "Modification Estimate").
If SPECTRADYNE approves the Modification Estimate in writing to CERPLEX then
CERPLEX shall implement the Service Modification and SPECTRADYNE shall pay the
appropriate charges, if any, in accordance with the agreement of the parties as
confirmed in a written Modification Agreement.

     6.3  MUTUAL COOPERATION.  Each party agrees to provide all cooperation
reasonably necessary to effect additions, modifications, relocation and removals
of equipment, facilities and personnel requested by the other party necessary
for such party to meet its contractual commitments in a timely, efficient
manner.

     7.7 LIMITED RESTRICTION. Notwithstanding any other provision of this
Article 7, nothing in this Article 7, or any other agreement or instrument
entered into by the CERPLEX Parties in connection with the transactions
contemplated hereby, shall limit, prohibit, or restrict the CERPLEX Parties'
right to use during the Term hereof or after any termination of this Agreement
any manufacturing, testing or repair process, technique, method or system, or
the know-how associated therewith that CERPLEX possessed prior to the date
hereof and used in connection with its performance of the Services or the Work
rendered to SPECTRADYNE hereunder ("CERPLEX Know-how") or any Enhancements of
the CERPLEX Know-how that are or may have been derived therefrom.

                                   ARTICLE 8
                                    PRICING

     8.1 ANNUAL TARGET. At Closing, and thereafter every 30 days during the
Term, SPECTRADYNE will deliver to CERPLEX a minimum aggregate dollar purchase
target, with corresponding prices for the goods and services to be purchased,
for the immediately following 12-month period (the "Rolling Annual Target").
SPECTRADYNE shall be permitted to amend the minimum aggregate dollar purchase
target delivered at Closing (for the 12-month period commencing with the
Closing) upward only on or before February 1, 1994. So long as SPECTRADYNE
purchases from CERPLEX goods and services during each such Rolling Annual Target
period with an aggregate cost of at least equal to the Rolling Annual
Target,,the following pricing arrangements shall apply throughout the Term of
this Agreement:

          8.1.1 PRICE SCHEDULE. Except as specified below and in Section 6.2
above, prices for any SPECTRADYNE Products manufactured by or for SPECTRADYNE
prior to Closing shall not exceed the prices as specified on Schedule 8.1
attached hereto. If SPECTRADYNE delivers to CERPLEX on or before February 1,
1994 an upwardly revised minimum aggregate dollar purchase target for the 12-
month period beginning with the Closing, CERPLEX shall make dollar volume price
adjustments using the same methodology used to generate Schedule 8.1, which
price adjustments shall, however, be prospective only and applicable only to
purchase orders delivered after the date such upwardly revised minimum aggregate
dollar purchase target is delivered to CERPLEX.

                                       19

 
          8.1.2 NO PRICE INCREASE. If CERPLEX accepts a Rolling Annual Target,
the prices of goods and services may not be increased during the 12-month period
applicable to that Rolling Annual Target, subject to the provisions of Paragraph
8.2 below.

          8.1.3 PURCHASE ORDERS. At the Closing, SPECTRADYNE shall place with
CERPLEX a 90-day firm purchase order. Every 30 days thereafter during the Term
SPECTRADYNE shall amend the existing firm purchase order to extend it for an
additional 30-day period with orders for such additional 30-day period. All
orders shall be placed on SPECTRADYNE's purchase order form attached hereto as
Schedule 8.1.3, which may be changed from time to time during the Term as the
parties may mutually agree, at prices established in the then applicable Rolling
Annual Target for each good or service included on such purchase order. Subject
to the provisions of Paragraph 8.6 below regarding long lead-time items, CERPLEX
shall fulfill each purchase order on a timely basis as provided in the purchase
order. If SPECTRADYNE cancels or modifies any purchase order outside of such
purchase order's terms and other than because of a CERPLEX default, the parties
will negotiate in good faith to reschedule the purchases provided for in such
purchase order. If the parties are not able to reach agreement following such
good faith negotiations, CERPLEX's damages shall be limited to the lesser of
CERPLEX's direct and unavoidable damages (after commercially reasonable efforts
to mitigate) from such cancellation or modification (including any applicable
third-party-supplier penalties for such cancellation or modification) or the
full purchase price under such purchase order. Under no circumstances will
SPECTRADYNE be liable for any cancellation penalties imposed by CERPLEX or for
any damages to CERPLEX for periods not covered by a firm purchase order.

     8.2 PRICE INCREASES. CERPLEX may request a price increase with respect
to any goods and services it provides under this Agreement in connection with
each revised Rolling Annual Target, such price increase to be effective,
however, beginning with the last 30-day period in the 12-month period applicable
to such revised Rolling Annual Target. In such case, SPECTRADYNE may solicit and
receive bids from third parties with respect to the goods or services, or both,
as to which CERPLEX seeks a price increase. SPECTRADYNE shall negotiate in good
faith with CERPLEX as to the matter but shall remain free to select the third-
party bidder following such negotiations. The parties acknowledge that if such
good faith negotiations reach an impasse, this may result in SPECTRADYNE ceasing
to buy, and CERPLEX ceasing to supply, after the period applicable to the
immediately preceding Rolling Annual Target the goods and services as to which
CERPLEX seeks a price increase.

          8.2.1 PRICE DISCUSSIONS. Notwithstanding anything in this Article
8, the parties agree that if pricing and cost issues arise during the course

                                       20

 
of performance of this Agreement, they will negotiate in good faith to resolve
any such issue to the mutual satisfaction of both parties.

     8.3  COST SAVINGS.  CERPLEX may propose design, production, process or
other changes in the goods and services offered by SPECTRADYNE with a view to
achieving cost savings.  No such changes shall be implemented without
SPECTRADYNE's approval.  If any such changes are accepted, the prices in the
Annual Target shall be reduced so as to reflect 50% of the cost savings realized
from such change.

     8.4 "PROTO-BUILD" SERVICES. Engineering and "prototype-building"
services may be requested by SPECTRADYNE, and if requested will be provided by
CERPLEX, at a price to be mutually determined by the parties. SPECTRADYNE shall
have the right to purchase standard CERPLEX raw materials at CERPLEX's cost.

     8.5 SHIPPING AND RECEIVING. Shipping and receiving services (including
tape shipments) shall be provided upon request for a fee of $3.00 per
transaction (each shipping/receiving document to constitute a separate
transaction).

     8.6 LONG-LEAD ITEMS. CERPLEX shall advise SPECTRADYNE from time to
time of any components or materials requiring such lead time for delivery as
would prevent CERPLEX from meeting any delivery obligations under anticipated
SPECTRADYNE purchase orders based on Rolling Annual Targets and of any penalty
or cancellation charge that the third-party supplier of such components or
materials imposes for reduction or cancellation of an order. If SPECTRADYNE
specifically authorizes CERPLEX in writing to place advance orders for
particular amounts of such long lead-time items in anticipation of SPECTRADYNE
orders, and if any such orders are placed and later canceled or reduced due to
actions by SPECTRADYNE, then, to the extent that CERPLEX cannot with
commercially reasonable efforts either use such items for other purposes or
reduce or cancel its order with the third-party supplier without incurring a
penalty or cancellation charge, SPECTRADYNE shall be responsible for any and all
costs and charges, including without limitation, cancellation penalties imposed
on CERPLEX by the third-party supplier to the extent caused by SPECTRADYNE's
actions. If SPECTRADYNE fails to give such written assurances in a timely
fashion, then it shall be required either to accept any delay in delivery of
products ordered by it from CERPLEX of which it was previously advised or pay
any premium necessary to obtain the item in a timely fashion.

                                       21

 
                                   ARTICLE 9
                             INVOICES AND PAYMENT

     9.1 INVOICES. For all goods and services set forth on the Price
Schedule, CERPLEX shall invoice SPECTRADYNE on a weekly basis. For any new or
special services as described, CERPLEX shall invoice SPECTRADYNE on a monthly
basis. CERPLEX shall submit such invoices on or about the last day of each
relevant period and only for those billable items which have actually been
delivered to SPECTRADYNE on or prior to the invoice date. SPECTRADYNE shall have
audit rights to all CERPLEX figures presented on such invoices.

     9.2 PAYMENT. SPECTRADYNE shall pay CERPLEX within fortyfive (45) days
after submission of each invoice. Except as provided in Article 13 in order to
enable CERPLEX to obtain financing with respect to the accounts receivable owing
from time to time from SPECTRADYNE to CERPLEX, SPECTRADYNE agrees not to off-set
any sums of any kind owing from CERPLEX to SPECTRADYNE against any invoice owing
to CERPLEX, and SPECTRADYNE agrees not to assert any counterclaim, or otherwise
refuse to pay, any of the invoices owing to CERPLEX based upon any present or
future indebtedness, liabilities, or other obligations or sums owing from
CERPLEX to SPECTRADYNE (including under the Lease).

     9.3  TAXES.  Payment of all federal, state and/or local taxes based on
Services provided under this Agreement shall be the responsibility of CERPLEX
including, without limitation, franchise taxes, state and local personal
property taxes, employment taxes for its employees and taxes based on the net
income of CERPLEX.  SPECTRADYNE shall either (1) pay to CERPLEX all sales and
use taxes levied with respect to the Services or (2) issue a resale certificate
to CERPLEX for such Services.  Each party shall reasonably cooperate with the
other in minimizing any applicable tax.  CERPLEX shall promptly reimburse
SPECTRADYNE for the portion of any prepaid taxes relating to any period after
the Commencement Date.

                                   ARTICLE 10

          11.1.1  TERMINATION FOR MATERIAL EVENT.

               (a) CURE PERIOD. Except as otherwise provided in this Section
11.1, in the event of an occurrence of any material breach of this Agreement by
either party, which breach is not cured within thirty (30) days after receipt of

giving rise to the breach), then the non-breaching party may terminate this
Agreement forty-five (45) days after notice of termination is given.

               (b) DELIVERY PERFORMANCE. In addition to SPECTRADYNE's rights
under Section 3.7, should more than 5% of products purchased by SPECTRADYNE from
CERPLEX in any 90-day period be delivered late, CERPLEX shall discuss the
situation with SPECTRADYNE, undertake a performance review, and take corrective
action to assure that such inadequate performance will not be repeated. If
CERPLEX fails to so act in a timely manner, or if the same problem reoccurs at
such levels, then, in addition, to any action for damages for such default,
SPECTRADYNE shall be free to terminate this Agreement on thirty (30) days notice
without penalty for early termination or cancellation of any orders.

               (c) QUALITY PERFORMANCE. SPECTRADYNE shall define and implement a
product acceptance methodology for measuring product functionality and
performance based upon standard industry quality auditing practices using lot

conform to SPECTRADYNE's product functionality or performance standards, CERPLEX
shall discuss the situation with SPECTRADYNE, undertake a performance review,
and take corrective action to assure that such inadequate performance will not
be repeated. If CERPLEX fails to so act in a timely manner, or if the same
problem reoccurs at such levels, then, in addition, to any action for damages
for such default, SPECTRADYNE shall be free to terminate this Agreement on
thirty (30) days notice without penalty for early termination or cancellation of
any orders.
