Dear Sakuraba-San:

TSI TelSys Inc. is pleased to provide our revised firm fixed price
proposal for
the DRTS Program Base-Band Equipment which incorporates the
results of the
reference  negotiation.  A negotiation overview sheet is attached
for your
convenience and provides a review of the pricing, delivery,
technical and
contractual elements of this proposal.

This quote shall remain valid from the above date to December 25,
1997.  The
information contained in this proposal is considered proprietary
to TSI TelSys
and must be kept confidential in accordance with our non-
disclosure agreement.

Please extend our thanks and congratulations to the Cornes &
Company team, who
have contributed a great deal to the success of this DRTS
proposal/negotiation
process.  We sincerely look forward to continuing this success
with Cornes on
the many opportunities ahead of us in Japan.

Should you have any technical questions regarding this proposal,
please contact
Mr. Jeff Shi at (410) 872-3955.  Any contractual questions may be
addressed to

Attachment A - DRTS Negotiation Overview

December 17, 1997

I.   Pricing -The pricing negotiated is based upon the
VME/VIPstation
     configurations attached herewith.

II.  Delivery - The following delivery schedules were agreed
upon*:
     a) Tsukuba Primary Station - Nov. 30, 1998
     b) Tsukuba Secondary Station (Low Rate) - Oct. 30,1998
     c) Tsukuba Secondary Station (High Rate) - Apr. 30, 2000
     d) Hatoyama (EOC) Station - June 30, 1998
     e) Redu (ESA) Station - Sept. 30, 1998

     The NRE effort described on the attached sheet "NEC DRTS
Custom
     Engineering Work" dated December 17, 1997, shall be performed
in parallel
     with the delivery of the Hatoyama (EOC) Station (40% of the
engineering
     effort will be linked to this effort), Redu Station (40% of
the
     engineering effort will be linked to this effort), Tsukuba
Primary Station
     (10% linked to this effort), and Tsukuba Secondary Station
Low Rate System
     (10% linked to this effort).

     * These delivery commitments are based upon contract award
and acceptance
     by TSI TelSys by December 25, 1997, unless otherwise agreed
to in writing.

I.   Technical Baseline - Our technical basis is the NEC Technical
     Specification "BBE Requirement (CCSDS-N-001)" received on
November 21,
     1997, as revised by the negotiation minutes dated December
16, 1997.
     Based upon this specification and subsequent negotiation, we
have provided
     configuration descriptions/diagrams, and an NRE list for the
DRTS program
     which identifies what customization is included in this
proposal.  TSI
     TelSys substantially meets the technical requirements found
in the
     specification noted above, however, TSI TelSys takes
exception to and/or
     requires clarification to a few requirements and these are
noted on the
     NRE list.

II.  Terms and Conditions - The terms and conditions negotiated
with Cornes and
     documented in Revision 5 dated December 2, 1997, will apply
to this order
     with the exception of payment terms.  Payment terms are under
     consideration by NEC/Cornes at this time. TSI TelSys proposed
a 20%
     payment at the time of contract acceptance (Net 30), 60% at
Factory
     Acceptance Test (Net 0), and 20% at the time of NEC
Acceptance (Net 30).
     We anticipate closure on this issue prior to December 25,
1997.  Payment
     of the NRE is proposed to be on the same percentage basis as
a deliverable
     and will be linked to the Hatoyama Station (40%), Redu
Station (40%),
     Tsukuba Primary Station (10%), and Tsukuba Secondary Station
Low Rate
     System (10%).

Dear Mr. Ogita:

TSI TelSys is pleased  to  offer  two  originals  of  the  final

acknowledging  and
   agreeing to the payment terms and suggesting minor revisions.

<circle>  TSI  TelSys  letter dated November 4, 1997, agreeing to

15. INFRINGEMENT

TSI  TelSys, at its expense, will defend Customer against any
claim based on an
allegation that a product furnished hereunder infringes a patent
or copyright
of another in the United States, and TSI TelSys will pay any
resulting costs,
damages, and attorneys' fees finally awarded against Customer that
are
attributable to such claim, or will pay the part of any settlement
that is
attributable to such claim; provided, that: 1) Customer notifies
TSI TelSys
promptly in writing of the claim; 2) TSI TelSys is permitted to
control the
defense or settlement of the claim; and 3) Customer cooperates
reasonably in
such defense or settlement at TSI TelSys' expense.

In its defense of settlement of any such claim, TSI TelSys may:
1) procure for
Customer the right  to continue using the product;  2) modify the
product so
that it becomes non-infringing;  or 3) replace the product with an
equivalent
product not subject to such claim.  If the use of any product
furnished
hereunder is enjoined and none of the preceding alternatives is
reasonably
available to TSI TelSys, TSI TelSys will provide Customer an
opportunity to
return the product and receive a refund of the purchase price
paid, less a
reasonable allowance for use.

TSI TelSys shall have no liability to Customer for claims of
infringement based
upon:  1) the use of any product in combination with any product
not supplied
by TSI TelSys or; 2) the use of any product designed,
manufactured, or modified
to the specifications of Customer.

The foregoing states the entire obligation and liability of TSI
TelSys with
respect to infringement and claims thereof.

16. LIMITATION OF LIABILITY

EXCEPT AS PROVIDED IN THE PRECEDING SECTION REGARDING
INFRINGEMENT, IN NO EVENT
SHALL TSI TELSYS OR ITS VENDORS BE LIABLE FOR ANY DIRECT,
INDIRECT, SPECIAL,
INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING OUT OF CUSTOMER'S
PURCHASE OR USE
OF ANY PRODUCT, EVEN IF TSI TELSYS OR THE VENDOR HAS ADVANCE
NOTICE OF THE
POSSIBILITY OF SUCH DAMAGES.

17. WAIVER

The failure of either party to enforce at any time any provision
of these terms
and conditions shall not be construed to be a waiver of such
provision or the
right thereafter to enforce each and every provision.  No waiver
by either
party, either express or implied, of  any breach of any of these
terms and
conditions shall be construed as a waiver of any other breach of
such term or
condition.

18. ASSIGNMENT

Customer may not assign or otherwise transfer its rights or
obligations
hereunder without the prior written consent of TSI TelSys.  No
attempt to
assign or transfer in violation of this provision shall be valid
or binding
upon TSI TelSys.

19. GOVERNING LAW

The rights of the parties hereunder shall be governed by the laws
of the State
of Maryland, USA.

20. NOTICES

All notices required or authorized by these  terms and  conditions
shall be
given in writing and shall be deemed effective upon receipt (this
includes
facsimile receipts).  Notices to Customer shall be sent to the
address shown in
the Customer's order.

21. DISPUTES

Any disputes arising under this contract shall be settled by
compulsory,
binding arbitration between the parties hereto in accordance with
the
commercial arbitration rules of the State of Maryland, USA.  If
the parties
cannot agree upon an arbitrator within thirty (30) days after
demand by either
of them, either or both parties may request the State of Maryland
to name a
panel of five (5) arbitrators.  TSI TelSys shall strike the names
of two (2) on
this list, the Representative shall then strike two (2) names, and
the
remaining name shall be the arbitrator.  Any reviews of the
Arbitrator's
decision shall be made in accordance with the Maryland Uniform
Arbitration Act











TSI TelSys Inc.'s Limited Hardware Warranty
V6A 4/8/97

TSI TelSys Inc.'s ("TELSYS") Warranty obligations are limited to
the terms set
forth below:

1.  LIMITED WARRANTY.  TELSYS warrants this hardware product
against defects in
materials and workmanship, under normal use and service, for a
period of one
(1) year from the date of receipt by the Purchaser.

If the Purchaser discovers a defect within the warranty period,
TELSYS will, at
its discretion, repair the product with either new or refurbished
replacement
parts at no charge.  If TELSYS is unable to restore the product to
good working
order, TELSYS will replace the product with either new or
refurbished
equipment, at its discretion.  In the event that TSI TelSys is
unable to repair
or replace the defective equipment, it will provide a refund for
the purchase
price of the product.  All products that are replaced will become
the property
of TELSYS.  Any replaced or repaired product is warranted for the
remainder of
the initial warranty period or ninety days, whichever is longer.
TELSYS shall
not be responsible for any software, firmware, information or
memory data of
the Purchaser contained in, stored on, or integrated with any
products for
system components returned to TELSYS pursuant to any warranty.

2.  RETURN PROCEDURES.  To obtain service under this warranty
within the
established period, the Purchaser must:

Call TELSYS Technical Service Support Operations at 1-888-849-CARE
(2273)
between 8 a.m. and 5 p.m. EST, Monday through Friday, excluding
holidays.

To insure that your product qualifies for return to factory
warranty service,
you will be asked to provide the model and serial number of your
product, the
date of original purchase, and the Purchaser's name, address, and
phone number.

Products returned to TELSYS' Technical Service Support Operations
must be pre-
authorized by TELSYS with a Return Material Authorization (RMA)
number marked
on the outside of the package, and sent prepaid, insured, and
packaged
appropriately for safe shipment.  The repaired or replaced item
will be shipped
to the Purchaser at TELSYS' expense, not later than (90) ninety
days after
receipt by TELSYS.

3.  APPLICABILITY.

This warranty applies only to hardware products (including
internal components)
supplied by TELSYS that can be identified by the "TELSYS"
trademark, trade
name, or logo affixed to them.  Any warranty on external third-
party hardware
(i.e., Sun Workstation) installed by TELSYS with this product is
provided by
the hardware vendor, not TELSYS.  This warranty does not apply to
damage caused
by accident, abuse, misuse, improper installation or testing,
misapplication,
or service (including upgrades and expansions) performed by anyone
who is not a
TELSYS Authorized Service Provider or any other cause beyond the
range of the
intended use, or by fire, lightning, or other hazard; if the
product has been
modified without the written permission of TELSYS; if any TELSYS
serial number
has been removed or defaced; or if you cannot provide proof of
original
purchase as described above.

4.  LIMITATIONS OF REMEDIES AND DAMAGES.

IN NO EVENT WILL TELSYS, ITS PARENT OR SUBSIDIARIES OR ANY OF THE
LICENSORS,
DIRECTORS, OFFICERS, EMPLOYEES OR AFFILIATES OF ANY OF THE
FOREGOING BE LIABLE
TO THE PURCHASER FOR ANY CONSEQUENTIAL, INCIDENTAL, INDIRECT OR
SPECIAL DAMAGES
WHATSOEVER (INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF
BUSINESS
PROFITS, BUSINESS INTERRUPTION, LOSS OF BUSINESS INFORMATION AND
THE LIKE,)
WHETHER FORESEEABLE OR UNFORESEEABLE, ARISING OUT OF THE USE OF OR
INABILITY TO
USE THE SOFTWARE OR ACCOMPANYING WRITTEN MATERIAL, REGARDLESS OF
THE BASIS OF
THE CLAIM AND EVEN IF TELSYS OR A TELSYS REPRESENTATIVE HAS BEEN
ADVISED OF THE
POSSIBILITY OF SUCH DAMAGE.  TELSYS'S LIABILITY TO THE PURCHASER
FOR DIRECT
DAMAGES FOR ANY CAUSE WHATSOEVER, AND REGARDLESS OF THE FORM OF
THE ACTION,
WILL BE LIMITED TO THE ACTUAL PURCHASE PAID FOR THE PRODUCT.

Some states do not allow the exclusion or limitation of incidental
or
consequential damages or exclusion of implied warranties, so the
above
limitations or exclusions may not apply to the Purchaser.  This
warranty gives
the Purchaser specific legal rights, and the Purchaser may also
have other
rights that vary from state to state.

THE WARRANTY AND REMEDIES SET FORTH ABOVE ARE EXCLUSIVE AND IN
LIEU OF ALL
OTHERS, WHETHER ORAL OR WRITTEN, EXPRESS OR IMPLIED.  TELSYS
SPECIFICALLY
DISCLAIMS ANY AND ALL IMPLIED WARRANTIES, INCLUDING, WITHOUT
LIMITATION,
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  UNLESS
MODIFIED IN WRITING AND SIGNED BY THE AUTHORIZED REPRESENTATIVES
OF BOTH
PARTIES, THIS WARRANTY IS UNDERSTOOD TO BE THE COMPLETE AND
EXCLUSIVE WARRANTY
BETWEEN THE PARTIES.  NO TELSYS SALES REPRESENTATIVE, DEALER,
RESELLER, AGENT
OR EMPLOYEE IS AUTHORIZED TO MAKE ANY MODIFICATION, EXTENSION, OR
ADDITION TO
THIS WARRANTY UNLESS OTHERWISE ALLOWED BY THIS AGREEMENT.

                                 April 8, 1997

TSI TelSys agrees to indemnify and hold Cornes & Co. harmless from

result of

orders.  An
overview of our discussions on payment terms is provided below for
your
confirmation and approval:

Scenario #1:

This scenario is characterized by an on-site (at TSI TelSys)
customer witness
and approval of factory acceptance testing.  The milestones for
payment of this
type of contract are detailed as follows:

     Milestone             Amount           Payment Terms

     Contract Award        25% of CV*       Net 30 days

     FAT                   55% of CV        Immediate

     Customer Acceptance   20% of CV        Net 30 days

Scenario #2:

This scenario is characterized by customer witness and approval of
acceptance
testing at the customer site only.  The milestones for payment of
this type of
contract are detailed as follows:

     Milestone             Amount           Payment Terms

     Contract Award        25% of CV        Net 30 days

     Customer Acceptance   75% of CV        Per terms of LOC


The letter of credit terms are proposed as a separate addendum to
this letter.
In this scenario, since TSI TelSys will not receive payment until
the letter of
credit terms are satisfied, it is appropriate that title pass upon
End-Customer
acceptance at their plant.  Therefore, the F.O.B. point for these
types of
orders shall be "Customer's Plant".  TSI TelSys will take
responsibility for
shipment of the products to the Tokyo Airport and request that
Cornes, as our
importer, take responsibility on our behalf in transporting the
equipment to
the Customer site.  All additional costs related to transporting
the equipment
(including, but not limited to, freight forwarder, shipping, and
insurance
costs) will be billed separately to Cornes and shall be paid on
Net 30 day
terms.

In the unlikely event that Customer acceptance is not granted
within thirty
(30) days of installation, TSI TelSys reserves the right to
require return of
the equipment to facilitate remediation or negotiate other
arrangements with
Cornes, at TSI TelSys' sole discretion.

Scenario #3:

In the rare cases that our contract situation does not fit into
the first two
scenarios, the parties agreed to remain open minded and
cooperative in
discussing alternative payment terms which are appropriate for
that contract.

Please indicate your acceptance to this change to this proposal by
signing the
block below and returning a copy via facsimile to my attention.
Thank you for
your consideration.

Sincerely,

TSI TelSys Inc.

FACSIMILE MESSAGE
From Cornes & Co. Ltd., Tokyo
Date: 7 October 1997

TO: TSI TelSys Inc.
ATTN: Mr. K. Matsumoto
CC: Mr. E. O'Malley

From: Norio Ogita, Manager, Business Administration

Subject: Agreement

Thank you for your fax of 18 September and we will make the
following comments.

We agree with your proposal of scenario 1, 2 and 3. These 3
scenarios might be
stipulated in the side letter attached to the formal agreement and
you remain
the old (you proposed previously) wording in the formal agreement,
i.e. Art.
No. 13 of Exhibit B, Payment. Please refer the last paragraph of
our fax of 24
July 1997.

As far as we understand, scenario 3 should be applicable, if we
can not obtain
the customer's consent of payment of 25% at the time of contract,
although we
will try to avoid such a case.
We should be pleased, if you would confirm this before signing.

We put our signature and return the attached document on the
payment.

One thing we would like to comment is the wording on L/C.
We normally receive a document from our bank and they state on the
document
"irrevocable documentary credit" in stead of stating "irrevocable,
non-
transferable letter of credit".

Best regards,


N. Ogita
Manager, Business Administration

Subject:   Cornes Purchase Orders

Reference: Cornes facsimile dated October 7, 1997

Dear Mr. Ogita:

TSI TelSys Inc. is pleased to confirm our agreement to the
reference letter.
Specifically, we will consider our letter of September 16, 1997,
to be
incorporated into our previously negotiated terms of April 8,
1997, via
attachment.  These payment terms will supersede those relevant
sections found
in Article 13 of Exhibit B.

TSI TelSys agrees to handle scenario 3 on a case-by-case basis and
has no
problem with Cornes position on this issue.  We agree to revise
the letter of
credit wording from "irrevocable, non-transferable letter of
credit" to an
"irrevocable documentary credit" as Cornes proposed.

Thank you for your patience and follow-up in bringing these issues
to closure.

Should you have any questions regarding this letter, please
contact me at (410)

Sincerely,

TSI TelSys Inc.
