has expressed an interest to manufacture and OEM such drives.  Tandberg will 
look favorably upon such request from Overland, and will be willing to 
discuss the possibility to manufacture and OEM such drives and consider 
allowing Overland to obtain such rights given that this is within the spirit 
of cooperation of the Agreement and provided that it is commercially viable 
to Tandberg.
     
     3.17   It is further agreed that either party's on-going obligation to 
pay royalties to the other based on the use of know-how or trade secret 
information received from such other (exclusive of patent rights) shall not

     5.7    To the extent that Overland's know-how, design criteria and test 
data concerning its VR(2) Technology has been reduced to documentary form as 
defined in EXHIBIT H (hereinafter "VR(2) Technology Information"), all such 
"VR(2) Technology Information" shall, during the Development Period, be 
deposited in a third party escrow commencing as soon after the Effective Date 
hereof as is reasonably practicable (but no later than 30 days following the 
Effective Date hereof) and this third party escrow shall be updated to be 
reasonably current throughout the term of the Development Period.  Overland 
shall advise Tandberg promptly of the identity of such third party escrowee.  
The third party escrowee shall be instructed to turn over all such "VR(2) 
Technology Information" to Tandberg in the event, and only in the event, that 
during the Development Period, (a) the Overland contracting party, or its 
Parent, if any, declares bankruptcy or (b) a Takeover of the Overland 
contracting party, or its Parent, if any, has occurred.  In this event, 
Overland will continue to support Tandberg on a "best efforts" basis.  
Tandberg will control this know-how as a trade secret and will not pass this 
know-how to any other party except as a necessary part of a manufacturing 
sublicense.  Failure to turn over all such "VR(2) Technology Information" to 
the escrowee as provided herein or to disclose to Tandberg the identity of 
such third party escrowee shall constitute a material breach of this 
Agreement.

data concerning the manufacture of its MLR Drives has been reduced to 
documentary form as defined in EXHIBIT I (hereinafter "MLR Manufacturing 
Technology Information"), all such "MLR Manufacturing Technology Information" 
shall, throughout the period preceding full manufacturing by Overland be 
deposited in a third party escrow commencing as soon after the Effective Date 
hereof as is reasonably practicable (but no later than 30 days following the 
Effective Date hereof) and this third party escrow shall be updated to be 
reasonably current throughout the period preceding full manufacturing by 
Overland.  Tandberg shall advise Overland promptly of the identity of such 
third party escrowee.  The third party escrowee shall be instructed to turn 
over all such "MLR Manufacturing Technology Information" to Overland in the 
event, and only in the event, that (a)  the Tandberg contracting party, or 
its Parent, if any, declares bankruptcy or (b) a Takeover of the Tandberg 
contracting party, or its Parent, if any, has occurred.  In this event, 
Tandberg will continue to support Overland on a "best efforts" basis.  
Overland will control this know-how as a trade secret and will not pass this 
know-how to any other party.  Failure to turn over all such "MLR 
Manufacturing Technology Information" to the escrowee as provided herein or 
to disclose to Overland the identity of such third party escrowee shall 
constitute a material breach of this Agreement.
     
     5.9    In the event that either of the parties hereto gains access to 
escrowed information of the other, prior to the planned transfer of such 
information pursuant to the Agreement, neither will use the information 
unless absolutely required to maintain the operation of permitted programs 
after all reasonable alternatives to gain a solution without utilizing this 
information have been exhausted.  In all cases, either party's use of such 
escrowed information shall be subject to the licenses and other terms and 
conditions of this Agreement.  In the event that Overland does not require 
usage of the escrowed information (because Tandberg is supporting Overland), 
then all such information shall be immediately returned to escrow following 
full manufacturing by Overland as described herein.
     
     5.10   Tandberg shall determine how much of its know-how will be shared 
with Overland engineers during the Development Period.  Tandberg will make 
available to Overland all know-how required by Overland to support Overland's 
assembly and test and full manufacturing efforts.  Overland will control all 
know-how received as trade secret and will not pass this know-how on to any 
third party or use it for design of tape drives.
     
     5.11   It is agreed that each party shall use the other party's know-how 
and intellectual property only to the extent required to implement the MLR 
VR(2) Development Program except that Tandberg may use VR(2) Technology know 
how for the purpose of designing and manufacturing other tape drives.

     7.9    In the event that Tandberg wants to make an improvement to the 
VR(2) Technology following the Development Period, Tandberg may make such 
change independently of Overland and use it for any purpose. Overland will 
provide sufficient design information to allow Tandberg to effectively make 
such improvement. If Tandberg requests that Overland assist, and Overland 
agrees to assist, in making the improvement, then Tandberg will pay for 
Overland's development costs. Tandberg will own the intellectual property 
relating to the improvement, and Overland may license or sub-license such 
improvement to the VR(2) Technology for use on any tape drive other than an MLR 
VR(2) Drive or a future tape drive developed by Tandberg which employs VR(2) 
Technology, by entering into a written license agreement with Tandberg on 
mutually agreed reasonable terms and conditions. If either Overland or 
Tandberg makes an improvement to VR(2) Technology, and such improvement is 
utilized within MLR VR(2) Drives or future tape drives developed by Tandberg 
which employ VR(2) Technology, then no royalty will be

     12.1   This Agreement shall begin on the Effective Date and shall remain
in effect until terminated by the parties by mutual agreement or by the other
termination provisions of this Agreement, provided however that following two
years from the Effective Date hereof, either party may terminate this Agreement
without cause as provided in this Article by giving one hundred eighty (180)
days' written notice.  In the event of a breach, the breaching party will have
ninety (90) days after receipt of notice from the non-breaching party to cure
any such breach.
     
     12.2   The effect of termination of this Agreement on the licenses granted
herein and certain obligations of the parties are set forth in EXHIBIT L.  The
obligations of the parties with respect to maintenance of  trade secret
information, know-how protection and confidentiality shall survive termination
of this Agreement.
     
     12.3   Should a situation occur, related to the MLR VR(2) Drive which 
makes it practically unrealistic to complete the MLR VR(2) Development 
Program within any kind of reasonable time and cost limits, either party 
shall have the right to terminate this Agreement on one hundred eighty days 
notice unless otherwise mutually agreed.  The test shall be whether it 
objectively appears that the project is commercially reasonably possible 
within a reasonable period of time. The two companies shall consult and 
advise each other prior to such a decision, and also agree that they will do 
their best to avoid that such a situation shall occur. However, the parties 
may agree to terminate the development work if the product will become so 
severely delayed or so expensive that it will become obviously 
non-competitive in the market.  The parties agree to consider reasonable 
solutions before the work is eventually terminated.  In the event that the 
VR(2) Technology is successfully implemented in an MLR Drive and MLR VR(2) 
Drives can be effectively produced at Tandberg but for any reason the set up 
of a manufacturing line for MLR or MLR VR(2) Drives at Overland cannot be 
successfully completed, then and in that event, Tandberg shall continue to 
have the rights to the VR(2) Technology subject to the price increases in 
Exhibit D.

     12.4   In the event that the implementation of the VR(2) Technology in the
MLR Drives is not successful within *** of the Effective Date hereof, either
party may declare this Agreement terminated and such termination shall take
place *** following such declaration and in such event, the obligations of the
parties with respect to maintenance of

trade secret information, know-how protection and confidentiality, and those 
obligations specified in Section 3.8 and Exhibit L, shall continue.

     12.5   In the event of any good-faith termination, each party agrees that
it shall absorb all costs it incurred with respect to the Development Program to
the date of termination without seeking indemnification from the other party.

     12.6   If either of the parties fails to exercise a good faith effort to
fulfill its commitments under this Agreement as fast as is reasonably
commercially feasible, then after written notice specifically identifying such
party's failure to exercise good faith and failure to cure the specified problem
within a ninety-day (90-day) period of time, the Agreement is terminated and the
effects of such termination are set forth in Exhibit L.

     15.5   A party (the "indemnitee") which intends to claim indemnification 
under this Article 15 shall promptly notify the other party ("the 
indemnitor") in writing of any action, claims, or liability in respect of 
which the indemnitee or any of its employees or agents intend to claim such 
indemnification.  The indemnitee shall permit, and shall cause its employees 
and agents to permit, the indemnitor to settle any such action, claims, or 
liability and agrees to the control of such defence or settlement by the 
indemnitor; provided, however, that such settlement does not adversely affect 
the indemnitee's rights hereunder or impose any obligations on the indemnitee 
in addition to those set forth herein.  No action, claim, or liability shall 
be settled without the prior written consent of the indemnitor, and the 
indemnitor shall not be responsible for any attorneys' fees or other costs 
incurred other than as provided herein.  The indemnitee, its employees and 
agents, shall cooperate fully with the indemnitor and its legal 
representatives in the investigation and defence of any action, claim, or 
liability covered by this indemnification.  The indemnitee shall have the 
right, but not the obligation, to be represented by counsel of its own 
selection and at its own expense.

programs or that the performance or work under this Agreement will result in 
the development of commercial products.  Both parties assume the risk that 
the development programs will not produce the results required.

American Arbitration Association, ("AAA") will be the Appointing Authority 
and will appoint a single arbitrator.  The arbitration case will be 
administered by the AAA in accordance with its "Procedures for Cases Under 
the UNCITRAL Arbitration Rules" ("Rules"). The place of arbitration will be 
Chicago, Illinois, and the exclusive language to be used for the arbitral 
proceedings will be English. 
     
     c.     Ancillary Relief.  Nothing herein will prevent a party, prior to 
appointment of the arbitrator, from making application to any court of 
competent jurisdiction, for a temporary restraining order or any other 
provisional remedy available at law or in equity not cognizable by 
arbitration.  Such application for relief will not constitute a waiver of 
this agreement to arbitrate.  Upon appointment, the arbitrator will have 
exclusive authority to order provisional or interim relief, except that any 
relief ordered by the arbitrator may be immediately and specifically enforced 
by a court otherwise having jurisdiction. The parties waive objection to 
venue and consent to the personal jurisdiction of the federal courts of 
Chicago, Illinois, U.S.A. in any action to enforce this agreement to 
arbitrate or any order or award of the arbitrator, or for the provisional or 
interim remedies provided for in this Agreement.
     
     d.     Expenses.  In any arbitration proceeding pursuant to this
Agreement, each party will bear the expenses of its witnesses.  All other costs
of arbitration, including, without limitation, the fees and expenses of the
arbitrators, the cost of the record or transcripts thereof, if any,
administrative fees, the attorneys' fees of the parties, and all other fees and
costs will be allocated to the parties to the arbitration as determined by the
arbitrator, except that the prevailing party in such arbitration will be
entitled to recover its reasonable attorneys' fees and expenses.
     
     e.     Discovery.  Discovery will be limited to written requests for the 
production of specific documents.  The period for requesting documents will 
be 60 days commencing upon the day that the answer is due under the Rules.  
The responding party will have 30 days to produce the requested documents by 
sending copies to the requesting party or its representative via a recognized 
international courier service.  The parties will also voluntarily produce all 
documents that they intend to use at the arbitration hearing and a list of 
intended witnesses before the close of discovery subject to supplementation 
for purposes of rebuttal or good cause shown.  The parties waive any right to 
seek any discovery not provided for in this Agreement irrespective of whether 
the laws of any country provide for different or additional discovery in 
international arbitration.  The arbitrator will hold a pre-hearing conference 
within three days of the close of discovery and will schedule and hold the 
final hearing within 30 days of the close of discovery.
