to Seller or any third party with respect to any material commitments or
production arrangements in excess of the amounts or in advance of the times
necessary to meet Buyer's delivery schedules set forth in its Releases. Except
as set forth in purchase orders issued pursuant to Schedule 3(a), Buyer may
cancel any outstanding Release at any time, in its sole discretion, and shall
only be liable for finished goods, work in process or ordered materials that
cannot be cancelled for the withdrawn Release.


4. PRICING

         (a) Price Protection. The market-basket prices specified in Schedule
1(a) for the Products related to this Agreement (the "the Prices") are firm

and in its acknowledgement of Buyer's Release shall confirm delivery dates or
propose alternatives to Buyer.

         (b) Changes. Buyer may increase the individual weekly Release

amount greater than that set forth in the prior sentence, Seller and Buyer shall
mutually determine a price and delivery adjustment to apply to the Product
falling outside of such parameters.

6.  INTELLECTUAL PROPERTY

         (a) Buyer's Property. Buyer will not provide Seller with any property
under this agreement.

         (b) Seller's Property. Neither this Agreement nor the sale of Products
from Seller to Buyer shall transfer title of any of Seller's intellectual
property rights to Buyer. Seller shall remain the exclusive owner of all of its
intellectual property rights (including, without limitation, any patent,
trademark, trade secret, or copyright) in and to the Products and any
documentation or training materials provided by Seller to Buyer. Buyer shall not
manufacture, duplicate, reverse engineer, or decompile the hardware, software,
or any part of the Product or information relating thereto.

         (c) License. Seller grants to Buyer and its customers or users of
Buyer's products containing Products a perpetual, paid-up, worldwide,
non-exclusive, irrevocable license to use, in the operation, maintenance and
repair of the Products, any software and/or firmware supplied by Seller to
Buyer.

         (d) Protection of Rights. No rights are granted to Seller, by Buyer,
under any of Buyer's patents, copyrights, trade secrets or other property rights
except as may be expressly agreed to by Buyer. Seller will not use or
incorporate into Products any intellectual property of others without their
written permission. Without limiting Seller's indemnity with respect to
intellectual property, if the use of a Product or any part thereof is enjoined
by a court, Seller will, at Buyer's option and Seller's expense, either procure
for Buyer the right to continue using the Product or part, replace the same with
a non-infringing equivalent, or remove the Product, refund the purchase price
and reimburse Buyer for any related costs incurred by Buyer.

         (e) Customer Copies. Unless agreed otherwise in writing by Buyer, each
Product delivered by Seller shall have associated with it a manual or other form
of documentation containing all applicable software license(s), software
documentation other than source code, spare part lists, theory of operation,
service troubleshooting diagnostics, and instructions necessary for the
installation, operation, maintenance and repair of the Product. The
documentation shall be in a format and language acceptable to Buyer, and shall
be delivered immediately to Buyer upon Buyer's request. Prices for such
documentation are listed on Schedule 1(a).

                                      -5-


7. INSTALLED BASE SERVICE AND REPAIR

         Seller shall maintain for ten years from the last shipment of a Product
the capability to replace or repair (which may include re-engineering) the
Product and furnish documentation, spare parts, service tools and instruments
necessary to service the Product effectively.


8. COMMERCIAL TERMS

         (a) Transportation. Seller shall ship Products to Buyer using Buyer's
designated carrier with transportation charges billed directly to Buyer by the
carrier. Seller shall not pay premium transportation charges unless authorized
by Buyer in writing. Seller shall list any unauthorized charges not otherwise
billed to Buyer as a separate line item on Seller's invoice. If Seller ships
Products by an unauthorized method or carrier, Seller shall pay any resulting
increased freight costs. Seller shall release rail or truck shipments at the
lowest valuation permitted and will not declare value on Products shipped.

         (b) Title and Risk of Loss. Title and risk of loss will pass to Buyer
when the Products are delivered to Buyer's designated carrier. All shipments
shall be F.O.B., place of shipment.

         (c) Shipments. Seller agrees to make shipments in the quantities and at
the times specified in any Release. Each shipment shall include a packing list
that contains the Purchase Order number, product identification, quantity
shipped, date of shipment and such other information as Buyer may require.
Unless otherwise expressly stated, time is of the essence. In the event any
shipment is not made on the date and in the quantity set forth on the Release,
Buyer may:

         (i)      return to Seller some or all of the Products in the shipment
                  at Seller's risk and expense, including without limitation
                  warehouse or handling cost;

         (ii)     purchase substitute products elsewhere and charge Seller with
                  any resulting loss; or

         (iii)    direct Seller to make an expedited shipment of additional or
                  replacement Products, with the difference in cost between any
                  expedited routing and the Release routing to be paid by
                  Seller.

Buyer shall consult with Seller prior to exercising any of the remedies
available to Buyer in this subsection.

<PAGE>
                                      -6-



Seller agrees to notify Buyer immediately if Seller ever has reasonable cause to
suspect that any Product will not be delivered as ordered, or a shipment will
not be made as scheduled.

         (d) Inspection And Rejection. Products are subject to Buyer's right of
inspection and rejection for compliance with applicable specifications. Unless
Buyer provides notice of rejection to Seller within a reasonable time, the
Product shall be deemed accepted. In the event that Buyer rejects the Product
pursuant to this Section 8(d), the warranty period for such particular unit
shall be extended by the period of time the particular unit is in transit and
held by Seller. The making of any payment does not restrict Buyer's right to
make a warranty claim with respect to defects in Products. Seller agrees to
provide and maintain inspection and process control systems acceptable to Buyer
with respect to the manufacture of Products, and Seller agrees to keep and make
available complete records of all of Seller's inspection work and process
control work for the life of the Products, as defined by Buyer. Buyer may
inspect the Products at any place of manufacture during production without
waiving its right subsequently to reject or revoke acceptance for undiscovered
or latent defects. Buyer's failure to inspect and accept or reject Products will
not relieve Seller from any obligations.

         (e) Conflicting Terms. The provisions of this Agreement, when in
conflict or inconsistent with the terms and conditions of any purchase order or
with Buyer's Standard Terms and Conditions, shall supersede such other terms and
conditions.


9. INVOICES/PAYMENT

         (a) Content of Invoice. Seller's invoices shall contain the Release
number, item number on such release, GEMS part number, invoice quantity, unit of
measure, unit price, total invoice amount, name of Seller, phone number, address
to which remittance should be sent, and such other information as may be
required by Buyer.

         (b) Payment. Payment terms shall be 1% 15 net 60 days after receiving
both the Product and an invoice prepared in accordance with the terms of this
Agreement.


10. WARRANTY/REPAIR

(a)      Warranty.  Seller represents and warrants that the Products will:

                  (i)      be owned by Seller and free of all liens, claims or
                           encumbrances;

<PAGE>
                                      -7-


                  (ii)     conform strictly to all express specifications,
                           drawings, plans, instructions, samples or other
                           descriptions; and

                  (iii)    be free from defects in design, material and
                           workmanship, whether latent or otherwise for twelve
                           (12) months from date of delivery to Buyer.

Seller agrees to extend to Buyer's customers and Buyer (and to cooperate with
Buyer to enforce) any warranties received from Seller's suppliers.

         (b) Intellectual Property Representation. Seller represents and
warrants that the Products will not knowingly infringe any U.S. or foreign
patent, registered U.S. copyright, or registered U.S. trademark of a third
party.

         (c) Return of Non-conforming or Defective Product. Buyer may return any
non-conforming or defective Product to Seller. Seller will repair or replace, at
its option, any Product which Seller determines was properly used and maintained
and was not in compliance with the warranty in Section 10(a) during the warranty
period. Any product returned must have a Return Material Authorization (RMA)
number obtained from Seller to allow processing and tracking of the return. Any
such Product shall be returned to Seller's facility or authorized service
center, with all transportation charges paid by Seller as specified in the RMA
and the risk of loss passing to Seller when the Product is delivered to the
carrier of Buyer's choice. Buyer shall reimburse Seller for all shipping charges
for non-warranty returns.

         (d) Limitation of Warranty. SELLER MAKES NO OTHER GUARANTEES OR
WARRANTIES WHATSOEVER, AND THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES,
EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS
FOR A PARTICULAR PURPOSE.

         (e) Limitation of Liability. SELLER'S MAXIMUM LIABILITY ARISING OUT OF
ITS PERFORMANCE UNDER THIS AGREEMENT, WHETHER IN CONTRACT OR IN TORT, INCLUDING
NEGLIGENCE, IS LIMITED TO THE LESSER OF $500,000 OR REFUND OF THE COMPENSATION
RECEIVED BY SELLER UNDER THIS AGREEMENT. IN NO EVENT WILL SELLER BE LIABLE FOR
ANY LOST PROFITS OR INCIDENTAL OR CONSEQUENTIAL DAMAGES REGARDLESS OF WHETHER
SELLER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, NOR ANY CLAIM
AGAINST BUYER BY ANY OTHER PARTY.

                                      -8-


11. INDEMNIFICATION

         (a) Seller's Indemnification. Seller agrees to defend, indemnify and
hold Buyer and Buyer's customers harmless from and against any and all claims
(including without limitation claims for infringement of intellectual property,
breach of contract, death or injury to a person or injury to property, or other
tort claims), liabilities, damages (whether direct or indirect, incidental or
consequential) and expenses (including court costs and attorneys' fees) arising
out of or relating to the breach by Seller of any covenant, representation or
warranty, or from any act or omission of Seller or Seller's agents, employees or
subcontractors. Buyer will notify Seller of any such claim, suit or proceeding
and will assist Seller (at Seller's expense) in the defense of the same.

         (b) Buyer's Indemnification. Buyer agrees to defend, indemnify and hold
Seller harmless from and against any and all claims (including without
limitation claims for infringement of intellectual property, breach of contract,
death or injury to a person or injury to property, or other tort claims),
liabilities, damages (whether direct or indirect, incidental or consequential)
and expenses (including court costs and attorneys' fees) arising out of or
relating to the breach by Buyer of any covenant, representation or warranty, or
from any act or omission of Buyer or Buyer's agents, employees or
subcontractors. Seller will notify Buyer of any such claim, suit or proceeding
and will assist Buyer (at Buyer's expense) in the defense of the same.


12. COMPLIANCE

         (a) General. Seller shall comply with all applicable laws and
regulations in furnishing Products. Such laws may include, but not be limited
to, United States and foreign medical device laws, labor laws, employment
opportunity laws, environmental laws and product safety laws.

         (b) Product Certification. Seller shall maintain at its expense UL,
IEC, CE and CSA or equivalent listings acceptable to Buyer for all Products.
Unless otherwise agreed to in writing, if a party proposes a change in purchase
specifications pursuant to Article 13, such party shall be responsible for any
additional product certification costs that may be necessary.

         (c) Product is a Component. The parties agree that the Products are
components, and not medical devices, as those terms are used in the FDA's
Quality System Regulation ("QSR"). As such, the manufacture of the Products
shall not be required to be in compliance with the QSRs. Buyer is responsible
for obtaining approval or clearance from the FDA or other governmental agencies
for products containing the Products or into

<PAGE>
                                      -9-


which the Products are integrated. Buyer shall provide Seller with a copy of the
approval or clearance letter allowing commercial distribution of the products
containing the Products. Seller shall cooperate in providing, as required,
information to governmental agencies in order to obtain and maintain necessary
approvals. Buyer's documentation retention of manufacturing quality records will
be in accordance with QSRs.

         (d) Buyer shall be responsible for recall and field corrective action
involving the Product or any Buyer product that contains a Product. Payment of
any costs associated with a recall or field corrective action shall be discussed
and mutually agreed-upon by the parties.

         (e) Buyer will, if Buyer deems it necessary, advise Seller of any
complaints, as that term is defined in the QSRs, involving the Products, and
Seller will determine whether an investigation is needed, and, if required,
conduct an investigation.


13. CHANGES IN PURCHASE SPECIFICATIONS

         (a) Buyer-Proposed Changes. Buyer may propose changes in the Products
relating to this Agreement by submitting the proposed changes (identifying those
changes which it deems mandatory to make the Product suitable for use) to the
agreement manager of Seller, utilizing the Product Change Notice (PCN). Seller
shall respond in writing to the agreement manager of Buyer within ten (10) days
after receipt of such changes with the following information, as applicable: (i)
lead time required to implement proposed changes; (ii) impact of proposed
changes on pricing of Product, including parts and tools; (iii) impact of
proposed changes on inventory, scrap material and work in process; and (iv)
non-recurring engineering charges to implement proposed changes. Within no more
than ten (10) days after Buyer receives Seller's response to Buyer's proposed
changes, the parties shall begin negotiations with respect to the changes to the
Products and any related changes to the price and delivery schedules. If the
parties fail to negotiate appropriate changes to the Agreement, the terms in
effect prior to the commencement of the negotiations shall remain in full force
and effect. Buyer shall pay for all costs Seller incurs in connection with
changes to the Products, including, without limitation, those required in order
to comply with applicable regulatory requirements. At Seller's request, Buyer
shall provide written certification that the requested change does not require
prior clearance or approval by the Food and Drug Administration (FDA). If FDA
approval or clearance is required, Buyer shall obtain the approval or clearance
before the change is implemented.

         (b) Seller-Proposed Changes. Seller may not make any changes to the
Product without obtaining Buyer's written Product Change Notice (PCN). Seller
may not make

<PAGE>
                                      -10-


any manufacturing process or engineering design changes to any Product delivered
to Buyer without submitting a Supplier Change Notice (SCN), at least ninety (90)
days before the change is implemented. If Seller makes any such change to a
Product without such documentation, Seller shall, in addition to any other
costs, expenses or damages incurred by Buyer, be responsible for labor and
material costs to repair or replace said Product at Buyer's facility or Buyer's
customer site regardless of whether the Product is in or out of warranty.


14. TERMINATION

         If there is a material breach of any material term of this Agreement by
Seller or Buyer and Seller or Buyer, respectively, fails to correct such breach
within thirty (30) days after receiving written notice of such breach from the
other party, the other party may terminate this Agreement and all unfilled
Releases without any liability except for the price of any Products previously
delivered and accepted by Buyer (subject to any set-off available to Buyer);
provided, however, that this shall not limit Buyer's obligations under purchase
orders containing the provisions required by the document attached as Schedule
3(a). Buyer may also terminate this Agreement immediately by giving written
notice to Seller if Seller fails to meet its financial obligations as they
become due, or if any proceeding under the bankruptcy or insolvency laws is
brought against Seller, or a receiver is appointed for Seller or Seller makes an
assignment for the benefit of creditors. Any such termination shall not relieve
Seller of its obligations and Buyer shall retain all legal and equitable
remedies after such termination. A material breach by Seller shall include,
without limitation, the failure by Seller to comply with any product quality and
delivery obligations.


15. INFORMATION

         The parties have entered into that certain Non-disclosure Agreement
("NDA") dated June 18, 2001, a copy of which is attached hereto, and that NDA is
incorporated herein and shall terminate three (3) years after the termination of
this Agreement.


16. AGREEMENT MANAGER/NOTICES

         (a) Managers. Each party shall appoint an agreement manager as the
point of contact for all matters relating to performance of this Agreement.
Buyer's agreement manager shall be John Harold and Seller's agreement manager

to the other party.

         (b) Addresses. Any notice required under this Agreement shall be sent

17.  DISPUTE RESOLUTION

         Any dispute, controversy or claim relating to this Agreement (a

mediator chooses to withdraw sooner. At the request of either party, the
mediator will be asked to provide an evaluation of the Dispute and the parties'
relative positions. Each party shall bear its own costs of mediation effort. If
the Dispute cannot be resolved through mediation, either party may commence an
action to resolve the Dispute in the Commercial Division of the New York State
court in New York County, it being agreed that the parties submit to the
jurisdiction of that court. The prevailing party shall be entitled to receive
from the other party its attorneys' fees, experts' fees, costs and expenses. THE
PARTIES EXPRESSLY WAIVE AND FOREGO ANY RIGHT TO TRIAL BY JURY.


18. GENERAL MATTERS

obligation by the other party to a third party.

of Buyer's products or its name in promotional activity, or otherwise publicly
announce or comment on this Agreement without Buyer's prior written consent.

written consent of Buyer.

         (d) This Agreement may be modified only by a writing signed by the

indemnification or any other provision that would inherently survive the
termination of this Agreement shall survive the termination of this Agreement.

SRFD II RF Amplifier & Interface Purchase Specification Doc. No. 2230683PSP Rev.
F, attached as Schedule 19(a) hereto (as modified by mutual agreement, the
"SRFDII Specifications").

         (b) In consideration for (i) the pricing concessions provided by Seller
to Buyer as set forth in Schedule 1(a); and (ii) the rebates set forth in
Schedule 19(e), Buyer shall purchase from Seller:

                  (i)      Three (3) prototype SRFDII units @ $33,000 ea.
                           deliverable September, 2001. For the purposes of this
                           Agreement, "prototype unit" shall mean a unit that
                           meets the basic performance specifications as set
                           forth by Buyer. These units shall be largely
                           compliant with Buyer's purchase specifications in
                           terms of form-factor and electrical performance. This
                           unit shall be built and tested by Seller under
                           pre-release documentation and should not be
                           considered "sellable" by Buyer.

                  (ii)     Ten (10) pre-production SRFDII units @ $22,000 ea.
                           (delivery intended by December 31, 2001 and to be
                           mutually agreed to by the parties at the time Buyer
                           submits the purchase order). For the purposes of this
                           Agreement, "pre-production unit" shall mean a unit
                           which is in compliance with Buyer's purchase
                           specifications. These units shall be "sellable" by
                           Buyer.

                  (iii)    Two Hundred (200) production SRFDII units @$17,500
                           ea. (GE is committed to receive the 200 units by
                           6/30/02) (delivery dates shall be mutually agreed to
                           by the parties at the time Buyer submits the purchase
                           order).

                  (iv)     One Hundred (100) production SRFDII units @ $16,250
                           ea. (GE is committed to receive the 100 units by
                           12/31/02) (delivery dates shall be mutually agreed to
                           by the parties at the time Buyer submits the purchase
                           order).

Buyer shall add the production units referenced in this subsection to its
Release system not later than November 24, 2001.

The SRFDII prototype and pre-production units will be delivered to Buyer "as
is", and without the warranties set forth in Section 10(a) of this Agreement. At
such time as Buyer submits Releases for production units of the SRFDII as set
forth in Section 19(b)(iii) and (iv), the production SRFDII units shall be
Products under this Agreement and all provisions of this Agreement (other than
Section 19(c)) shall apply to the SRFDII.

         (c) Seller agrees that its delivery of Products to Buyer under this
Agreement will meet Buyer's 90% on-time delivery requirement (excluding
Buyer-caused lateness) for the

<PAGE>
                                      -14-



current basket of goods and services (does not pertain to SRFDII). "Buyer's 90%
on-time delivery requirement" shall mean a score of 90% or more on the GE
Scorecard for deliveries of all Products under this Agreement. If Seller cannot
maintain an average score of 90% over a rolling four-month period for on-time
delivery performance for Products, Buyer retains the right to cancel its
commitment to purchase SRFDII units as set forth in Section 19(b) above.

         (d) Buyer agrees to exclusively use Seller's System Support Modules
("SSMs") in Seller's production of its .35 T, .70 T, 1.0 T and 1.5 T MR systems
until December 31, 2002.

         (e) In consideration for Buyer's agreement to purchase the items set
forth in Section 19(b)(i)-(iv), and to reimburse Buyer for its costs associated
with designing the SRFDII into Buyer's products, Seller shall make rebates to
Buyer as set forth in Schedule 19(e) (the "Rebates"). In the event Seller does
not for any reason fully comply with its obligations under Section
19(b)(i)-(iv), Buyer will return to Seller all savings in excess of $300,000
that Buyer has received through the application of the Rebates and the pricing
reflected in Schedule 1(a).

                  GE'S OFFER TO EXTEND FINISHED GOODS LIABILITY

[Letterhead of GE Medical Systems]
General Electric Company
P.O. Box 414, Milwaukee, WI 53201-0414

June 21, 2000

Re:  Offer to Extend Finished Goods Liability

Dear Mr. Cone:

In our ongoing commitment to improve productivity, reliability and quality, GE
Medical Systems (GEMS) is currently involved in several Six Sigma projects to
improve its forecasting and ordering processes. As part of that effort, GEMS has
chosen a few select suppliers who will receive additional ordering assurances
and commitments by GEMS if those suppliers agree to assist GEMS with its
processes. You have been chosen as one of those suppliers, and as a selected
supplier, GEMS would like to extend its liability to you on forecasted products
in order for GEMS to avoid potential shortages on those products listed in
Attachment A.

As you are aware, historically, GEMS has provided you with forecasts of required
products and has then followed those forecasts with firm commitments for
delivery. As a result, GEMS has only been liable for products ordered as part of
the firm commitments and not as a result of the long-term forecasts. According
to suppliers we have surveyed, this process can result in shortages and delayed
delivery dates due to the suppliers' longer lead times for second tier supplier
parts. In order to avoid shortages and missed delivery dates due to these
reasons, GEMS is committing to its total forecasted product quantities through
June 30, 2002.

GEMS has issued purchase order 806537 to you as a firm commitment pursuant to
which GEMS shall purchase from you the quantities specified in Attachment A to
this letter. This commitment by GEMS serves to authorize your firm to commit to
both the materials and capacity required to ensure product availability through
June 30, 2002.

<PAGE>

                                      -2-

Purchase order 806537 shall incorporate by reference the following:

         ADVANCE FUNDING AUTHORIZATION FOR ELECTRONIC ASSEMBLY PROCUREMENTS

         THIS PURCHASE ORDER IS FUNDED IN AN AMOUNT OF $7,627,235 AS
         AUTHORIZATION TO CMED TO 1) ADVANCE ORDER COMPONENT PARTS, 2) ADDRESS
         CAPACITY CONSTRAINTS, AND 3) FACILITATE THE SUBSEQUENT MANUFACTURE OF
         THE ASSEMBLIES DELINEATED HEREIN PER THE SIGNAL REQUIREMENTS. THIS PO
         REPRESENTS A "SNAPSHOT" OF THE SUPPLIER SIGNAL SYSTEM FORECAST AS OF
         THE DATE HEREIN AND DEFINES OUR COMMITMENT IN TERMS OF THE QUANTITIES
         FOR EACH ASSEMBLY SPECIFIED THROUGH MARCH 31, 2002. THIS PO REFLECTS
         THE PROJECTED DELIVERY PROFILE AND WILL BE ADJUSTED THROUGH SIGNAL
         UPDATES. THE PRODUCTS LISTED HEREIN WILL BE DELIVERED AND INVOICED AS
         PART OF COMPLETED ASSEMBLIES AS SIGNALED THROUGH THE GEMS SUPPLIER
         SIGNAL SYSTEM. GEMS SHALL BE LIABLE FOR THE TOTAL AMOUNT OF FINISHED
         GOODS LISTED IN THE PO AS SET FORTH IN THE OFFER TO EXTEND FINISHED
         GOODS LIABILITY BETWEEN GEMS AND CMED DATED JUNE 21, 2001.

GEMS will continue to update the Supplier Signal System forecast each month as
part of its normal course of business. If at any time GEMS anticipates that the
total requirements for any assembly(ies) on Attachment A exceed the current
commitment level, you will be so notified and discussions will ensue to
determine, jointly, the best course of action.

This PO represents the total amount of products GEMS-MR plans on purchasing from
CMED and this PO is not to be shipped or billed against.

In return for this commitment by GEMS, you agree to the total quantity and
nominal weekly run rate identified under Attachment A, with material to be
delivered as pulled by weekly signals which will be within a +/- 25% band around
the nominal weekly run rate. To ensure that this objective is achieved, you
shall provide ongoing, bi-weekly feedback on the following performance
objectives: order placement and receipt (specifically for long lead time
components) proactive identification of obsolescence issues, and identification
of capacity constraints and the actions taken to resolve them.

In return for the commitment by CMED, GEMS shall purchase and take into
inventory by or before June 30, 2002 the quantity of remaining products listed
on Attachment A not previously purchased under purchase order No. 806537.

We are confident that such a firm commitment on our part will enable you to
successfully meet the end-of-year challenges ahead of us. Should you have any
questions with respect to the above, please contact me at your earliest
convenience.

Best regards,

/s/ John Harold

Re:  Offer to Extend Finished Goods Liability

Dear Mr. Cone:

In our ongoing commitment to improve productivity, reliability and quality, GE
Medical Systems (GEMS) is currently involved in several Six Sigma projects to
improve its forecasting and ordering processes. As part of that effort, GEMS has
chosen a few select suppliers who will receive additional ordering assurances
and commitments by GEMS if those suppliers agree to assist GEMS with its
processes. You have been chosen as one of those suppliers, and as a selected
supplier, GEMS would like to extend its liability to you on forecasted products
in order for GEMS to avoid potential shortages on those products listed in
Attachment A.

As you are aware, historically, GEMS has provided you with forecasts of required
products and has then followed those forecasts with firm commitments for
delivery. As a result, GEMS has only been liable for products ordered as part of
the firm commitments and not as a result of the long-term forecasts. According
to suppliers we have surveyed, this process can result in shortages and delayed
delivery dates due to the suppliers' longer lead times for second tier supplier
parts. In order to avoid shortages and missed delivery dates due to these
reasons, GEMS is committing to its total forecasted product quantities through
June 30, 2002.

GEMS has issued purchase order 806537 to you as a firm commitment pursuant to
which GEMS shall purchase from you the quantities specified in Attachment A to
this letter. This commitment by GEMS serves to authorize your firm to commit to
both the materials and capacity required to ensure product availability through
June 30, 2002.

Purchase order 806537 shall incorporate by reference the following:

<PAGE>

                                      -4-

         ADVANCE FUNDING AUTHORIZATION FOR ELECTRONIC ASSEMBLY PROCUREMENTS

         THIS PURCHASE ORDER IS FUNDED IN AN AMOUNT OF $7,627,235 AS
         AUTHORIZATION TO CMED TO 1) ADVANCE ORDER COMPONENT PARTS, 2) ADDRESS
         CAPACITY CONSTRAINTS, AND 3) FACILITATE THE SUBSEQUENT MANUFACTURE OF
         THE ASSEMBLIES DELINEATED HEREIN PER THE SIGNAL REQUIREMENTS. THIS PO
         REPRESENTS A "SNAPSHOT" OF THE SUPPLIER SIGNAL SYSTEM FORECAST AS OF
         THE DATE HEREIN AND DEFINES OUR COMMITMENT IN TERMS OF THE QUANTITIES
         FOR EACH ASSEMBLY SPECIFIED THROUGH MARCH 31, 2002. THIS PO REFLECTS
         THE PROJECTED DELIVERY PROFILE AND WILL BE ADJUSTED THROUGH SIGNAL
         UPDATES. THE PRODUCTS LISTED HEREIN WILL BE DELIVERED AND INVOICED AS
         PART OF COMPLETED ASSEMBLIES AS SIGNALED THROUGH THE GEMS SUPPLIER
         SIGNAL SYSTEM. GEMS SHALL BE LIABLE FOR THE TOTAL AMOUNT OF FINISHED
         GOODS LISTED IN THE PO AS SET FORTH IN THE OFFER TO EXTEND FINISHED
         GOODS LIABILITY BETWEEN GEMS AND CMED DATED JUNE 21, 2001.

GEMS will continue to update the Supplier Signal System forecast each month as
part of its normal course of business. If at any time GEMS anticipates that the
total requirements for any assembly(ies) on Attachment A exceed the current
commitment level, you will be so notified and discussions will ensue to
determine, jointly, the best course of action.

This PO represents the total amount of products GEMS-MR plans on purchasing from
CMED and this PO is not to be shipped or billed against.

In return for this commitment by GEMS, you agree to the total quantity and
nominal weekly run rate identified under Attachment A, with material to be
delivered as pulled by weekly signals which will be within a +/- 25% band around
the nominal weekly run rate. To ensure that this objective is achieved, you
shall provide ongoing, bi-weekly feedback on the following performance
objectives: order placement and receipt (specifically for long lead time
components) proactive identification of obsolescence issues, and identification
of capacity constraints and the actions taken to resolve them.

In return for the commitment by CMED, GEMS shall purchase and take into
inventory by or before June 30, 2002 the quantity of remaining products listed
on Attachment A not previously purchased under purchase order No. 806537.

We are confident that such a firm commitment on our part will enable you to
successfully meet the end-of-year challenges ahead of us. Should you have any
questions with respect to the above, please contact me at your earliest
convenience.

Best regards,

/s/ John Harold

Waiver and Invalidity. Any waiver or renunciation of a claim or right arising
out of breach must be in writing and signed by the injured party. Any failure to

such provision or any other provision nor of the right to enforce such
provision. The invalidity, in whole or in part, of any provision hereof shall
not affect the remainder of the provisions.

Assignment. You may not assign any right or delegate any duty hereunder without
our prior written consent. Any attempted assignment or delegation by you will be
void.

Independent Contractor. You will be considered an independent contractor for all
purposes, and shall not be deemed to be our agent, employee or subcontractor

                         NON-DISCLOSURE LETTER AGREEMENT

[Letterhead of GE Medical Systems]
General Electric Company
PO Box 414
Milwaukee, WI  53201-0414

Date: June 18, 2001

Address:
Christopher Cone
Colorado MedTech
1811 Lefthand Circle
Longmont, CO 80501

Dear Mr. Cone:

         Discussions are to be entered into between representatives of Colorado
MEDtech, Inc. ("CMED") and General Electric Company (GE) relating to MR
subsystems. Both GE and CMED representatives now believe there is a need to
exchange certain information which is considered to be proprietary to the
respective parties (Proprietary Information). Each party is willing to disclose
its Proprietary Information as necessary under the terms and conditions set
forth below.

         1.       All information disclosed or furnished by one party to the
                  other which the disclosing party deems to be proprietary shall
                  be in writing and clearly identified on its face as being
                  proprietary. Oral disclosures deemed to be proprietary shall
                  be confirmed in writing as proprietary within 30 days by the
                  disclosing party. The receiving party agrees that for a period
                  of three (3) years it shall not disclose such Proprietary
                  Information to any third party nor use such Proprietary
                  Information for any purpose other than to evaluate its
                  interest in the mutual business described above. The receiving
                  party shall protect the information with the same degree of
                  care as it applies to protect its own Proprietary Information.

         2.       Notwithstanding the provisions of Paragraph 1 above, the
                  receiving party shall have no obligations with respect to any
                  information which (i) is or becomes known within the public
                  domain through no act of the receiving party in breach of this
                  Agreement, (ii) was in the possession of the receiving party
                  prior to its disclosure or transfer hereunder and the
                  receiving party can so prove, (iii) is independently developed
                  by the receiving party and the receiving party can so prove,
                  or (iv) is received from another source without any
                  restriction on use or disclosure.

<PAGE>

                                      -2-

         3.       Except for the obligations of the parties with respect to
                  Proprietary Information disclosed prior to expiration or
                  termination, this Agreement shall (unless extended by mutual
                  agreement) expire or terminate at the earliest of the
                  following events:

                  (a) One (1) year after the effective date of the Agreement, or

                  (b) Thirty (30) days after written notice of termination
                  provided by either party to the other.

                  Upon such expiration or termination either party may request
                  from the other party that any and/or all of its documents
                  containing Proprietary Information be returned, and the other
                  party shall so return such documents forthwith. The receiving
                  party may retain a copy of the Proprietary Information for
                  archival purposes.

         4.       No rights to any patents are provided or are to be implied by
                  any provision of this Agreement.


         5.       Nothing in this Agreement shall be construed as precluding the
                  receiving party at any time from independently developing
                  ideas, negotiating with, or entering into any agreement with
                  others relating to the general subject matter of this
                  Agreement; subject, however, to the provisions of paragraphs 1
                  and 2 hereof with respect to disclosure and use of
                  information.

         6.       This letter contains the sole and entire agreement between the
                  parties relating to the subject hereof and any representation,
                  promise, or condition not contained herein, or any amendment
                  hereto shall not be binding on either party unless set forth
                  in a subsequent written agreement signed by an authorized
                  representative of the party to be bound thereby.

         7.       This Agreement shall be construed in accordance with the laws
                  of the State of New York without regard to choice of law
                  provisions.

         If the foregoing provisions are acceptable to you, please signify your
acceptance by signing and returning the enclosed duplicate copy of this letter.
