         3.6 FURTHER ASSURANCES. After the Closing Date, Seller will execute and
deliver or cause to be executed and delivered, at its expense, any instruments
of conveyance and transfer and will take any other action Purchaser reasonably
requests to vest more effectively in Purchaser beneficial and record title to
the Assets and to put Purchaser in actual possession and operating control of
the Assets and, in the case of any contracts and rights, if any, to be
transferred hereunder to Purchaser but which cannot be transferred effectively
without the consent of third parties, to assure to Purchaser the benefits
thereof. Nothing contained in this Agreement shall constitute an agreement to
assign any account, claim, contract, commitment, sales order or purchase order
or any claim, right or benefit arising thereunder or resulting therefrom if an
attempted assignment thereof, without the consent of a third party thereto,
would constitute a breach thereof or in any way affect the rights of Purchaser
or Seller thereunder. Seller will cooperate with Purchaser in any reasonable
arrangement desired to provide for the realization by Purchaser of the benefits
after the Closing under any such accounts, claims, contracts, leases,
commitments, sales orders or purchase orders, including enforcement for the
benefit of Purchaser, at Purchaser's expense, of any and all rights of Seller
against a third party thereto arising out of the breach or cancellation by such
third party or otherwise. Purchaser will cooperate with Seller in any reasonable
arrangement desired to provide for the satisfaction by Seller of any of its
obligations under any such accounts, claims, contracts, commitment, sales orders
or purchase orders, including performance by Purchaser of such obligations as
subcontractor to Seller for consideration of any amounts received by Seller
after the Closing that constitute payments under such accounts, claims,
contracts, commitments, sales orders or purchase orders for post-Closing
activities.

         3.7 EMPLOYEE MATTERS. Purchaser agrees to make offers of employment to
the employees associated with the Panel Business listed in Schedule 3.7 hereto
(the


                                        5
<PAGE>   6
"Employees"), at their current salary, and with other benefits comparable to
current benefits of similarly situated employees of Purchaser. Seller shall
cause the Radian International LLC 401(k) Thrift Plan (the "RILLC Plan") to
fully vest each Employee employed by Purchaser with respect to each account of
such Employee in the RILLC Plan. Within one hundred twenty (120) days following
the Closing, the parties shall cause a plan to plan transfer of all accounts of
each Employee in the RILLC Plan to the Continental Circuits Corp. 401(k)
Retirement Plan. As soon as practicable following the Closing, Seller shall pay
to Purchaser the dollar amount of all vacation time accrued prior to the Closing
Date with respect to Employees accepting Purchaser's offer of employment based
upon the current pay rates shown in Schedule 3.7.

         4.6 INSURANCE. The Assets and the operations of the Panel Business of
an insurable nature have been continuously insured by Seller since the date of
opening of the Panel Business. Seller has provided to Purchaser a true, correct
and complete copy of all current insurance policies relating to the Panel
Business.

         4.7 LITIGATION. To the knowledge of Seller, there are no lawsuits,
proceedings, actions, arbitrations, claims or governmental investigations,
inquiries or proceedings pending or threatened, at law or in equity, against
Seller that relate to the Panel Business, nor is there any basis known to Seller
for any such action, and to the knowledge of Seller there is no action, suit or
proceeding by any person or agency pending or threatened which questions the
legality, validity or propriety of the transactions contemplated hereby.

         4.8 COMPLIANCE WITH LAWS, LICENSES. Except as described in the
documents referenced in the first clause of Section 4.13 or on Schedule 4.8,
Seller and the Panel Business have complied in all material respects with all
laws, regulations and orders, the noncompliance with which would adversely
affect the Assets or the operation of the Panel Business. Seller and the Panel
Business hold all licenses, permits, registrations, approvals, certificates,
contracts, consents, accreditations and franchises ("Licenses and Permits")
required to be held by them to own and operate the Assets and to conduct and
operate the Panel Business in compliance in all material respects with all
applicable laws and regulations. Schedule 4.8 describes each License and Permit
and a true and correct copy of each has previously been delivered to Purchaser
by Seller. All such Licenses and Permits are in full force and effect. To the
knowledge of Seller, Seller is not in default in any material respect under any
such License and Permit. No notice from any authority in respect to revocation,
termination, suspension or limitation of any License or Permit has been received
by Seller, nor is Seller aware of the proposed or threatened issuance of any
such notice. There is no basis known to Seller for any such action which would
have an adverse effect upon the liabilities, financial condition, results of
operation, business or prospects of the Assets or upon Purchaser's right to
conduct the business of the Panel Business as presently conducted. Except as
described on Schedule 4.8, Seller has not received any written inquiries
