Agreement shall be applicable with respect to the R2 Product only, except where
other products are expressly referenced.

                  2.2 Development. GEMS and R2 agree to jointly undertake a
                      ------------
technical collaboration to further develop specifications to define the
interface between the R2 Product and the GEMS Product and the compatibility of
the R2 Product with the GEMS Product.

                  2.3 Purchase and Distribution of Product. GEMS shall purchase
                      -------------------------------------
from R2, and R2 shall sell to GEMS, the R2 Product, and GEMS shall distribute
the R2 Product in the Territory, subject to the terms of this Agreement
(including without limitation, the provisions regarding exclusivity in Article

                  2.4      Purchases of R2 Product.
                           -----------------------

                           2.4.1    Purchase of Prototype.  GEMS shall
                                    ---------------------
purchase twenty (20) units of the R2 Product for the pilot customer accounts no
later than December 31, 2000; provided, however, that the obligation to purchase
such units shall be contingent upon the R2 Product being in a prototype phase
acceptable for pilot customer applications (regardless of whether the portion of
the GEMS Product being developed by GEMS is in a completed form acceptable for
pilot customer applications), and if this does not occur prior to December 31,
2000, then GEMS shall not have any obligation to purchase any such units. GEMS,
at its option, may purchase additional units of the R2 Product for the pilot
customer accounts, at the same GEMS Price as the initial twenty, subject to R2's
consent, such consent not to be unreasonably withheld.

                           2.4.2    Purchases After FDA Approval.  Except as
                                    ----------------------------

                  2.5 Subdistributors. Subject to the provisions of this
                      ----------------
Agreement, GEMS may appoint one or more third parties within any portion of the
Territory to distribute or act as a sales representative for the R2 Products to
end user customers (each a "Subdistributor"). GEMS agrees to terminate a
Subdistributor's right to distribute R2 Products promptly upon becoming aware
that such Subdistributor is selling or otherwise distributing R2 Products,
directly or indirectly, in a manner that is not in accordance in any material
respect with the provisions of this Agreement.

                  2.6 Reservation of Rights; No Rights Beyond the R2 Product.
                      -------------------------------------------------------
Except as expressly provided in this Agreement (including without limitation,
Section 14.4), (a) no right, title, or interest is granted, whether express or
implied, by R2 to GEMS, (b) nothing in this Agreement shall be deemed to grant
to GEMS rights in any products or technology other than the R2 Products, and (c)
no provision of this Agreement shall be deemed to restrict R2's right to exploit
technology, know-how, patents, or any other intellectual property rights
relating to the R2 Products in products other than R2 Products. It is further
understood and agreed that, subject to the provisions of this Agreement
(including without limitation, Section 14.4), R2 may itself, or with or through
third parties, (i) market, sell, or otherwise distribute, directly or
indirectly, R2 Products in Japan, and (ii) distribute products other than the R2
Product in the Territory, either directly or indirectly, for any purpose.
Without limiting the foregoing, such products may comprise hardware and/or
software that is part of the R2 Product provided that such products are not used
with Digital Based Mammography Systems. Following the end of the Exclusivity
Period, R2 may, through itself or through third parties, market, sell, or
otherwise distribute, directly or indirectly, the R2 Product in the Territory.

                  2.7 Independent Contractors. The relationship of GEMS and R2
                      ------------------------
established by this Agreement is that of independent contractors, and nothing
herein shall be construed to (a) give either party the power to direct or
control the day-to-day activities of the other, (b) constitute the parties as
partners, joint venturers, principal and agent, employer and employee,
co-owners, franchisor and franchisee, or otherwise as participants in a joint
undertaking, or (c) allow either party to create or assume any obligation on
behalf of the other party for any purpose whatsoever. Except as otherwise set
forth herein, all financial and other obligations associated with each party's
business are the sole responsibility of such party.

                  2.8      GEMS Cases.
                           ----------

                           2.8.1    Training Cases.  GEMS and R2 acknowledge
                                    --------------
that GEMS has provided to R2 data from one hundred (100) "normal cases" (cases
containing no indication of cancer). In order to assist R2 in developing a
prototype phase of the R2 Product as set forth in Section 2.4.1 and to obtain
regulatory approvals from the FDA and all other governmental and regulatory
approvals in the Territory, GEMS shall provide data no later than September 30,
2000 from a total of 200 "cancer cases" comprised of 100 cases containing an
indication of microcalcification and 100 masses, that will constitute a database
with a repartition in the pathology size corresponding to a screening population
(the "Cancer Cases"). Such screening population shall consist of the following
distribution guidelines: (a) lesions less than 2 cm.--at least 75% of the cases;
(b) lesions between 2 cm. and 3 cm.--no more than 20% of the cases; and (c)
lesions greater than 3 cm.--no more than 5% of the cases. Notwithstanding the



                                       5

<PAGE>

foregoing, GEMS and R2 acknowledge and agree that such distribution percentages
are to be used as guidelines for data collection and that R2 shall have no
remedy against GEMS if such distribution percentages are not met. Such case data
shall be provided by GEMS to R2 as soon as reasonably practicable after it is
available to or captured by GEMS and after appropriate informed consent has been
obtained from all affected subjects. GEMS shall proceed diligently to obtain
such appropriate informed consent.

                           2.8.2    Algorithm.  Prior to GEMS commencing
                                    ---------
discussions with the Institutional Review Board ("IRB"), R2 shall confirm in
writing to GEMS that the R2 Product algorithm can process the PMA (pre-market
approval) cases which are done in feasibility format and that R2 can use them
for the PMA submission. In the event that the FDA does not accept these cases
for R2's FDA submission, then GEMS and R2 shall negotiate in good faith to
determine how to acquire additional cases as outlined in Section 2.8.3.

                           2.8.3    FDA Cases.  Within fifteen (15) days of
                                    ---------
receipt by GEMS of written approval from the IRB, GEMS shall deliver to R2 the
PMA data set, consisting generally of 44 "cancer cases" and 100 "benign cases."
If the FDA requires more than the number of cases referred to above in order to
approve the R2 Product, then GEMS and R2 shall negotiate in good faith to
determine how many more cases need to be accrued, how to obtain them and how to
share the costs thereof.

                           2.8.4    Use and Return of Case Data.  R2 represents,
                                    ---------------------------
warrants and covenants to GEMS that the FDA cases, training cases and test data
provided under this Section 2.8, together with any and all other cases, training
databases and other related materials provided to R2 by GEMS will be used by R2
solely for the testing, development and regulatory approval of the R2 Product
for use with the GEMS Product exclusively, and, upon the request of GEMS will be
promptly returned to GEMS upon the termination of this Agreement or at any time
upon the request of GEMS. Upon the return of such information, R2 will provide
GEMS with a certificate from the president or chief financial officer of R2
certifying that all copies of such information have been returned to GEMS. None
of the information provided by GEMS shall identify any individual patient. All
such information provided to R2 under this Section 2.8 shall be deemed
"Confidential Information" under Section 12. R2 shall keep the training cases
and the FDA cases separate and shall not commingle the data from the two groups
of cases.

                           2.8.5    Test Cases.  After the training database
                                    ----------
requirements outlined in Section 2.8.1 are met, GEMS shall accrue a test
database. Such cases shall be used by R2 solely to evaluate the R2 Product
algorithm. The R2 Product algorithm shall be evaluated with R2 tools.
Representatives of GEMS shall participate in running the algorithm tests at R2's
offices and GEMS shall have the right to access and to receive copies of all
results and analyses of such tests, only for purposes related to this Agreement.
R2 represents, warrants and covenants that the test cases shall not be used by
R2 for any purpose other than such testing prior to the testing and analysis of
the algorithm as discussed above in this Section 2.8.5. If the results of the
testing reflect that the R2 Product is not meeting the Specifications, (a) then
the R2 Product shall not be released, unless otherwise agreed to in writing by
GEMS, and (b) GEMS and R2 shall share equally the test database in two halves:
(i) one half of the cases shall be added to the training database and (ii) the
other one-half of the cases shall remain in the test database. Any remaining



                                       6

<PAGE>

test cases (from subsection (ii) above) shall not be used for testing until the
next planned algorithm evaluation and shall be subject to the conditions of this
Section 2.8.5.

                  2.9 GEMS Products. Although GEMS shall not have any obligation
                      --------------
to purchase any minimum number of units of the R2 Product, GEMS hereby agrees
that from and after the Availability Date until the end of the Exclusivity
Period, GEMS shall include the R2 Product as integrated and packaged together
with at least * * * of the GEMS Products shipped or caused to be shipped by GEMS
(as measured on a quarterly basis); provided, however, that such obligation for
GEMS shall not be applicable during the first ninety (90) days following the
Availability Date; and, provided, further, that GEMS shall have sixty (60) days
after any written notice of default under this Section 2.9 from R2 to remedy any
such default (notwithstanding any other provision of this Agreement). GEMS shall
be relieved of its obligations under this Section 2.9, upon written notice to
R2, (a) if GEMS, acting in good faith, reasonably believes, as established by
contemporaneous written records that the R2 Product infringes a third party's
intellectual property rights, or (b) if, and then to the extent, that R2 is
unable to supply to GEMS or its customers in a sufficient quantity and on a
sufficiently timely basis to allow GEMS to meet such obligations. Upon such GEMS
written notice to R2, R2 has thirty (30) days to contest such alleged
infringement by providing written notice to GEMS. If the parties are not able to
reach agreement on how to remedy such alleged infringement within thirty (30)
days of R2's written notice of contest to GEMS, including without limitation
amending this Agreement, then either party may terminate this Agreement. If GEMS
fails to meet its obligations under this Section 2.9, and such failure is not
remedied within the time period set forth above, then R2 shall have the right,
as its sole and exclusive remedy for such failure, to terminate the exclusivity
provisions of this Agreement.

         3.       EXCLUSIVITY.
                  -----------

                  3.1 Exclusivity Obligations of Each Party. Subject to the
                      --------------------------------------
terms and conditions hereof, including without limitation, Sections 2.6 and 3.6,
during the Exclusivity Period (a) R2 shall not sell, lease, loan, license,
transfer or otherwise provide, or grant any distribution or other rights to
provide, directly or indirectly, the R2 Product to any manufacturer,
distributor, customer or other third party in the Territory (except in Japan
where such rights shall be non-exclusive), and (b) GEMS shall not purchase the
R2 Product from any third party. For the purposes of this Article 3, the R2
Product also shall be deemed to include any similar product configured for use
with any Digital Based Mammography System other than the GEMS Product.

                  3.2 Termination of Exclusivity for Both Parties. In the event
                      --------------------------------------------
the exclusivity provisions are terminated with respect to one party, they also
shall be deemed terminated with respect to the other party and the Exclusivity
Period shall terminate.

                  3.3 Termination of Exclusivity Obligations of R2.
                      ---------------------------------------------
Notwithstanding the provisions of Section 3.1, and subject to Section 3.5, the
obligation of R2 to sell the R2 Product exclusively to GEMS shall terminate, and
the Exclusivity Period shall terminate, at the sole option of R2: (a)
immediately upon termination of this Agreement; (b) upon the one (1) year
anniversary of the Availability Date; or (c) upon the election of R2 to
terminate exclusivity pursuant to the provisions of Section 2.9.

                  3.4 Termination of Exclusivity Obligations of GEMS.
                      -----------------------------------------------
Notwithstanding the provisions of Section 3.1, the obligation of GEMS to
purchase the R2 Product exclusively from R2 shall terminate, and the Exclusivity
Period shall terminate, at the sole option of GEMS, (a) immediately upon the
termination of this Agreement; (b) the one (1) year anniversary of the
Availability Date; (c) immediately if R2 is not able to supply R2 Product that
is commercially competitive with regard to cost, quality, delivery or service
taken in the aggregate, provided that if R2 cures such inability within ninety
(90) days after written notice is provided by GEMS to R2, then the exclusivity
provisions shall be reinstated; (d) subject to the provisions below in this
Section 3.4, thirty (30) days after written notice from GEMS to R2 if GEMS,
acting in good faith, reasonably believes, as established by contemporaneous
written records, that the R2 Product infringes the intellectual property rights
of any third party; (e) if GEMS or any of its Affiliates acquires, merges or
consolidates with a third party which supplies a product similar to the R2
Product; (f) if R2 is unable to supply the R2 Product because of a decision to
exit the business, insolvency or any other reason; (g) if R2 Files for
Bankruptcy; or (h) ninety (90) days after GEMS has provided R2 with written
notice of its intention to terminate exclusivity or (i) upon the election of R2
to terminate exclusivity pursuant to the provisions of Section 2.9. Upon GEMS
written notice to R2 pursuant to clause (d) above, R2 has thirty (30) days to
contest such alleged infringement by providing written notice to GEMS. If the
parties are not able to reach agreement on how to remedy such alleged
infringement within thirty (30) days of R2's written notice of contest to GEMS,
including without limitation amending this Agreement, then either party may
terminate this Agreement.

                  3.5 Sale of R2. In the event of a Change of Control of R2, R2
                      -----------
may, at its sole discretion, terminate the right of GEMS to purchase the R2
Product exclusively from R2, in which case the termination of exclusivity, and
the termination of the Exclusivity Period, would occur six (6) months after the
consummation of such Change of Control of R2; provided, however, that GEMS would
retain a non-exclusive right to sell the R2 Product for the Term of this
Agreement, including any extension period if GEMS has provided notice of its
intent to extend the Term in accordance with Section 15.1 prior to the effective
date of the Change of Control of R2. Notwithstanding the foregoing and as a
condition to the termination of exclusivity pursuant to this Section 3.5, prior
to entering into negotiations with any party regarding a Change of Control of
R2, R2 and its controlling shareholders shall first notify GEMS in writing of a
proposed Change of Control of R2, which notification shall not include the name
or identity of the other party or any information deemed confidential of such
other party, and shall negotiate in good faith with GEMS for a period of sixty
(60) days following receipt of such notice by GEMS, regarding a Change of
Control of R2 in which GEMS may acquire control of R2.

                  3.6      Ability to Collaborate with Other Parties, Etc.
                           -----------------------------------------------

Agreement, including without limitation,


                                       8

<PAGE>

distributing any software or hardware products developed by GEMS or its
Affiliates provided that such products are not directly competitive with the R2
Product, including any future version thereof; (b) GEMS shall have the right to
sell and distribute software or hardware products that may operate on the GEMS
systems provided that such products are not directly competitive with the R2
Product, including any future version thereof; (c) GEMS and R2 shall not be
prohibited from sharing their respective technical information with third
parties, subject to the parties' confidentiality agreements, in connection with
the development of software or hardware products that may operate with their
respective systems, whether or not such products may be competitive with the
other's products; and (d) GEMS and R2 shall have the right to develop internally
or to collaborate with third parties in connection with the development of
software or hardware products that may operate with their respective systems,
whether or not such products may be competitive with the other's products;
provided, however, that in no event shall GEMS or R2 enter into an agreement
with any third party, with an effective date prior to the end of the Exclusivity
Period under this Agreement, which grants such third party the right to sell,
purchase, distribute, market or promote CAD products for Digital Based
Mammography Systems prior to the end of such Exclusivity Period. The foregoing
provision shall not prevent either GEMS or R2 from discussing or negotiating
agreements or other relationships with third parties related to such CAD
products in advance of the termination of the exclusivity provisions hereof.

                  3.7 Effect of Termination of Exclusivity. Subject to
                      -------------------------------------
termination pursuant to Article 15, if the Exclusivity Period is terminated
pursuant to this Article 3, the remaining provisions of this Agreement shall
remain in full force and effect and Exhibit A to this Agreement shall
automatically be amended to reflect the most favorable price and discount terms
offered by R2 to any other purchasers or distributors of the R2 Product for
similar volume, terms, conditions and achievement of target license placements
of R2 Products, taken in the aggregate (taking into account all R2 Products
purchased or licenses placed by GEMS) ("Most Favored Customer Pricing").

         4.       PRICING AND PAYMENT.
                  -------------------

                  4.1 Pricing. With respect to each R2 Product purchased by GEMS
                      --------
hereunder, GEMS shall pay to R2 the GEMS Price for each R2 Product sold
hereunder. The GEMS Prices for R2 Products may only be revised as set forth in
Subsections 4.2, 4.3 and 4.4 below. All prices are quoted in United States
currency.

                  4.2      [Intentionally Omitted.]

                  4.3 Audit Right. GEMS shall have the right, upon reasonable
                      ------------
notice to R2, to have a third party independent auditing agency audit (or cause
such representatives or agents to audit) R2's books and records to determine (a)
R2's compliance with the "most favored customer" pricing terms set forth herein,
including without limitation in Section 3.7 and Exhibit A, and (b) R2's actual
manufacturing cost for the Hardware (as defined in Exhibit A) and spare parts.
The results of such audit shall be deemed to be R2 Confidential Information. If
an audit reflects that a lower price should have been charged or should be
charged to GEMS for units of R2 Product, then appropriate adjustments shall be
made to the GEMS Price, including any necessary adjustments for units previously
sold, where applicable. If the Manufacturing


                                       9

<PAGE>

Cost (as defined in Exhibit A) charged to GEMS differs from R2's actual
manufacturing cost by more than ten (10%) percent, then the Parties shall enter
into good faith negotiations to amend the GEMS Price, taking into account the
actual costs incurred by R2. The cost of the audit shall be paid by GEMS, unless
the audit reveals that (i) the GEMS Price charged to GEMS was not in accordance
with the Most Favored Customer Pricing, or (ii) R2's actual manufacturing costs
differ by more than ten percent (10%) from those included in the GEMS Price, in
which case R2 shall pay for the costs of the audit.

                  4.4 Taxes. R2 and GEMS shall negotiate in good faith to
                      ------
determine the extent to which the GEMS Price includes Taxes (as defined below)
and the extent to which GEMS will be obligated to pay Taxes in addition to the
GEMS Price. For purposes of this Section 4.5, "Taxes" shall mean any excise,
sales, use, value added (VAT), and withholding and similar taxes or duties
imposed by any government agency that has jurisdiction over the import, export,
or purchase of the R2 Products (other than taxes on net income of R2 or GEMS).

                  4.5 Payment. All payments shall be made in United States
                      --------
Dollars and are due net sixty (60) days after shipment by R2 of the R2 Product,
unless otherwise mutually agreed to by the parties.

                  4.6 Country of Origin. Invoices issued by R2 shall contain the
                      ------------------
country of origin of the Software (i.e., the country in which the item was
actually developed). R2 warrants and represents that for Software imported by
it, the country of origin on R2's invoice is correct and the Software is marked
conspicuously, legibly, indelibly and permanently in accordance with United
States law. For imported Software and Software produced or licensed within the
United States, R2 warrants and represents that it shall provide, upon request,
information or documentation establishing the country of origin.

         5.       REGULATORY MATTERS.
                  ------------------

                  The provisions of Exhibit F shall govern R2 and GEMS with
respect to regulatory matters and the other matters set forth therein. R2 and
GEMS each hereby agree to be bound by such provisions.

         6.       SOFTWARE LICENSE AGREEMENTS.
                  ---------------------------

                  GEMS acknowledges and agrees that, in cases where the Software
is distributed as a stand-alone item and not integrated into a GEMS Product, it
will use all commercially reasonable efforts to obtain agreement from its R2
Product customers to a commercially reasonable software license agreement (each
a "Software License Agreement"), such as the form provided in Exhibit C (with
such changes as the customer may reasonably request and R2 approves). GEMS shall
distribute Software in such cases only to end user customers who have entered
into a Software License Agreement in respect of such Software, unless R2
otherwise agrees.

         7.       OTHER SUPPLY TERMS.
                  ------------------

ordering, packaging, shipping, returning the R2 Product and other matters
relating to supply of the R2 Product shall be fixed by GEMS in a manner
consistent with its terms with other suppliers or as otherwise mutually agreed
by GEMS and R2.

         GEMS shall have the right to inspect shipment of R2 Product within 15
calendar days after receipt and shall notify R2 if any R2 Product is found by
GEMS to fail to meet Specifications. GEMS shall return rejected R2 Product to
R2, at GEMS' expense, including full risk of loss or damage to the R2 Product
for the shipment to R2, within a reasonable period of time of discovering the
failure and after first receiving a Return Material Authorization from R2, which
shall not be unreasonably withheld. No later than 15 calendar days after R2's
receipt of rejected R2 Product, R2 shall, at its option and expense if within
the Warranty Period, or at GEMS' option and expense as quoted by R2 outside of
the Warranty Period, either repair or replace said R2 Product. R2 shall bear all
expense and risk of loss or damage to R2 Product for the return shipment to
GEMS. R2 Product not rejected within 15 calendar days after receipt shall be
deemed accepted by GEMS.

                  -------

                  9.1 All Necessary License Rights. Subject to the provisions of
                      -----------------------------

intellectual property necessary to allow GEMS to perform its obligations and
exercise its rights under this Agreement. GEMS shall have a nonexclusive license
to use, sell, offer for sale and import the R2 Products during the Term which,
absent a license would infringe any or all of the Valid Claims and the Patent
Rights. GEMS and R2 acknowledge and agree that the purchase of each unit of an
R2 Product includes a license for a single acquisition device.

                  9.2 Rights upon Bankruptcy, Etc. Except as otherwise set forth
                      ---------------------------
in this Article 8, R2 hereby grants to GEMS a worldwide, perpetual, irrevocable,

source code from the Software, except under the circumstances described in
Section 9.6 or to the extent that any third party would be permitted to do so
under applicable law. GEMS shall not remove, alter, cover, or obfuscate any
copyright notices or other proprietary rights notices reasonably placed or
embedded by R2 on or in the Software.

                  9.5 Agreements Re: Existing Licenses. R2 and GEMS have entered
                      ---------------------------------
into agreements with Shih-Ping Bob Wang ("Wang") in connection with that certain
Exclusive License Agreement dated October 1, 1993 between Wang and R2, and with
ARCH Development Corporation ("ARCH") in connection with that certain License
Agreement I dated December 23, 1996, and that certain License Agreement II dated
December 23, 1996, each between ARCH and R2, that provide certain rights to GEMS
in the event that R2 Files for Bankruptcy. R2 represents and warrants that there
are no other licenses for the Patents that GEMS would require in such event to
enable GEMS to (a) use, execute, reproduce, display, perform, distribute, modify
and create derivative works of the Software or (b) make, have made, market,
offer for sale, sell and import the R2 Product for use in any market in the
Territory, except for licenses covering Patents Nos. 5,633,948 and 5,661,820
(the "Kegelmeyer Patents"), which to the best of R2's Knowledge (as defined in
Section 10.1.1) are not necessary, as of the date hereof, to (x) use, execute,
reproduce, display, perform, distribute, modify and create derivative works of
the Software or (y) make, have made, market, offer for sale, sell and import the
R2 Product for use in any market in the Territory. In the event that R2, in its
reasonable discretion, determines that the Kegelmeyer Patents are necessary for
GEMS to exercise the rights set forth in clauses (a) or (b) above, or in the
event the Kegelmeyer Patents are asserted against R2 or GEMS as a result of the
exercise of such rights by GEMS, then R2 shall obtain for GEMS a license to the
Kegelmeyer Patents as required for clauses (a) and (b) above.

                  9.6 Technical Information. In the event that R2 Files for
                      ----------------------
Bankruptcy, R2 shall provide to GEMS all necessary technical information
required for use with the R2 Product that it has not already provided in escrow
pursuant to Section 18.5, and GEMS shall have the unencumbered right to use all
of the technical information so provided or in escrow solely to commercially
exploit the R2 Product pursuant to Section 9.2 or to otherwise exercise it
rights hereunder.

                  9.7 Exclusivity and Term of Each License. Each license granted
                      -------------------------------------
by R2 to GEMS hereunder shall be exclusive (except in Japan where such rights
shall be non-exclusive) until the end of the Term (including any applicable
extension) and shall be non-exclusive thereafter. The term of each license
granted under this Agreement shall be concurrent with the Term, but shall
survive indefinitely and irrevocably with respect to the R2 Product in
accordance herewith marketed and sold prior to termination of this Agreement or
as provided under Section 15.5.

         10.      INTELLECTUAL PROPERTY WARRANTY
                  -------------------------------

                  10.1     R2 hereby represents to GEMS as follows:

                           10.1.1 R2 has license rights to the Patents set forth
in Exhibit E. The Patents cover portions of the Software incorporated into the
R2 Product. As of the date of this Agreement, R2 has received no notice of
infringement from any source. To the best of R2's


                                       13

<PAGE>

Knowledge (as defined below), the Patents are valid and enforceable and together
with any technical information to be provided by R2 to GEMS, represent all
intellectual property rights of R2 necessary for GEMS to perform its obligations
and enjoy its rights under this Agreement. For purposes of this Article 10,
"Knowledge" shall mean the Company's actual knowledge after due and diligent
inquiry of its officers, directors and employees reasonably believed to have
knowledge of the matter in question. GEMS agrees that R2 has the right to
defend, or at its option to settle, and R2 agrees, at its own expense, to defend
or at its option to settle, any claim, suit or proceeding brought against GEMS
or its customers on the issue of infringement of any third party United States
patent, copyright or trademark or the misappropriation of a trade secret by the
R2 Product distributed hereunder or the use thereof, subject to the limitations
hereinafter set forth in this Article 10. R2 shall have sole control of any such
action or settlement negotiations, and R2 agrees to pay any settlement amounts
or final judgment entered against GEMS or its customers on such issue in any
such suit, claim or proceeding defended by R2 (including reasonable attorney
fees, other professional fees, and other costs of litigation or settlement).
GEMS agrees to notify R2 promptly in writing of such claim, suit or proceeding;
provided that the failure to promptly notify R2 shall not relieve R2 of any
obligation under this Agreement except to the extent such failure to provide
prompt notice adversely impairs R2's ability to defend against the claim, suit
or proceeding; provided, that (i) R2 may not consent to imposition of any
obligation or restriction on GEMS in any settlement unless mutually agreed by R2
and GEMS, (ii) R2 shall keep GEMS fully informed and permit GEMS to participate
(at its own expense) as GEMS may reasonably request and (iii) GEMS may, without
affecting its right to indemnity hereunder, defend and settle any such claim,
suit or proceeding if R2 declines to defend against such claim, suit or
proceeding or Files for Bankruptcy. GEMS agrees to give R2 authority to proceed
as contemplated herein, and, at R2's expense, to give R2 information and
assistance to settle and/or defend any such claim, suit or proceeding. If the R2
Product, or any part thereof, are, or in the reasonable opinion of R2 may
become, the subject of any claim, suit or proceeding for infringement of any
patent, copyright or trademark or involves misappropriation of a trade secret,
or if it is adjudicatively determined that the R2 Product, or any part thereof,
infringes any patent, copyright or trademark or involves the misappropriation of
a trade secret, or if the distribution or use of the R2 Product, or any part
thereof, is as a result enjoined, then R2 may, at its option and expense: (a)
procure for GEMS and its customers the right under such patent, copyright,
trademark, or trade secret to distribute or use, as appropriate, the R2 Product
or any part thereof; (b) replace the R2 Product, or any part thereof, with
functionally equivalent products or parts that do not infringe or
misappropriate; (c) suitably modify the R2 Product, or any part thereof; or (d)
if the use of the R2 Product, or any part thereof, is prevented by injunction or
if the foregoing alternatives cannot be accomplished on a commercially
reasonable basis, remove the R2 Product, or any part thereof, discontinue sale
of such R2 Product hereunder without incurring any additional liability to GEMS,
and refund the aggregate payments paid therefor by GEMS.

                           10.1.2 Notwithstanding the provisions of Section
10.1.1, R2 assumes no liability for (a) any infringement claims with respect to
any product in or with which the R2 Product is used if such claims could not
reasonably be brought against the R2 Product standing alone; (b) any trademark
infringement involving any marking, or branding, not applied by R2 or involving
any marking or branding applied at the request of GEMS; or (c) modification of
the R2 Product, causing the infringement or any part thereof, unless such
modification is made by R2 or pursuant to R2's written direction or consent.

subsequently acquired by the receiving party from a third person having, to the
receiving party's knowledge, no obligation of confidentiality; (c) known to the
receiving party at the time of disclosure, as established by competent proof; or
(d) developed independently by or on behalf of the receiving party, without
reliance on or use of any Confidential Information of the other. In addition to
the foregoing, either party may use or disclose Confidential Information
disclosed to it by the other party to the extent such use or disclosure is
required by law, government agency, governmental regulation, court order or
valid discovery request in connection with a legal proceeding, provided that if

         15.      TERM AND TERMINATION.
                  --------------------

                       -----
from the date hereof until December 31, 2002 (as it may be extended, the
"Term"), unless earlier terminated in accordance with the provisions hereof.
GEMS shall have the option, upon written agreement from R2, to extend the Term
for two years (through December 31, 2004). Thereafter, the Term may be extended
on a year-to-year basis upon mutual consent of GEMS and R2. GEMS shall provide

                  15.3 Termination for Cause. If either party materially
                       ----------------------
defaults in its performance or breaches any material term or condition of this
Agreement, then the other party may give written notice to the breaching or
defaulting party that if the breach or default is not cured within thirty (30)
days, the Agreement may be terminated. If such notice is given and the material
breach or default is not cured during such thirty (30) day period, then the
party giving



                                       22

<PAGE>

notice of such breach or default shall thereafter have the right to terminate
this Agreement within twenty (20) days of the end of such 30-day cure period,
such termination to be effective immediately upon giving such notice to the
party in breach or default.

                  15.4 Termination If No FDA Approval. In the event that the
                       -------------------------------
Availability Date does not occur on or prior to March 31, 2001, R2, with the
reasonable assistance of GEMS where requested and where appropriate, will
attempt to resolve, during the ninety-one (91) day period following such date
(the "Remedy Period"), all open issues preventing the granting of FDA approval.
If the Availability Date does not occur prior to the end of the Remedy Period,
GEMS shall have the right, at its sole option, to terminate this Agreement or to
terminate its exclusivity obligations under Section 3.1. If the delay in R2's
obtaining FDA approval for commercial use of the R2 Product is a direct result
of a delay by GEMS in delivery of the FDA Cases or training case data to R2
pursuant to the terms of Section 2.8, then the Remedy Period shall be extended
by the same number of days of such delay caused by GEMS.

                  15.5 Other Termination Events. This Agreement shall also
                       -------------------------
terminate, at GEMS's sole option and discretion, (a) thirty (30) days after
written notice from GEMS to R2 if GEMS, acting in good faith, reasonably
believes that the R2 Product infringes the intellectual property rights of any
third party; (b) if R2 is unable to supply the R2 Product because of a decision
to exit the business, insolvency or any other reason; or (c) R2 Files for
Bankruptcy.

                  15.5 Fulfillment of Orders upon Termination. Upon termination
                       ---------------------------------------
of this Agreement by R2, R2 shall have the right, at its sole option, to require
GEMS to satisfy GEMS's obligations under all outstanding purchase orders that
have been accepted by R2 prior to the effective date of termination. Upon
termination of this Agreement by GEMS, GEMS shall have the right, at its sole
option, to require R2 to satisfy R2's obligations under all outstanding purchase
orders that have been accepted by R2 prior to the effective date of termination.
After the termination of this Agreement, to the extent that GEMS has, or will
have pursuant to the provisions of this Section 15.5, possession of units of the
R2 Product that it has not distributed or sold to third parties, GEMS shall have
the right to continue to market, distribute, and sell R2 Products in the
Territory pursuant to the terms hereof for a period of one hundred eighty (180)
days after termination of this Agreement. Notwithstanding anything herein to the
contrary, in the event that GEMS retains by statute the right to distribute or
sell R2 Products in the Territory to any customer or in any country after
expiration or termination of this Agreement, then the terms and conditions of
this Agreement shall remain in effect as to such customers or countries, as the
case may be, until such activities cease.

                  15.6 Effects of Termination. Termination or expiration of this
                       -----------------------
Agreement shall not relieve either party of obligations incurred prior to the
termination. Subject to the terms hereof, termination of this Agreement for any
reason shall result in termination of any R2 Product Subdistributorship granted
by GEMS.

                  15.7 Survival of Certain Terms. The provisions of Articles 5,
                       --------------------------
8, 10, 11.3, 11.4, 11.5, 12, 16 (only with respect to acts and/or omissions that
occur prior to the date of termination or expiration of this Agreement) and 17
shall survive the termination or expiration of this Agreement for any reason.
All other rights and obligations of the parties shall cease upon termination or
expiration of this Agreement, except as expressly provided herein.

         16.      INDEMNIFICATION.
                  ---------------

                  16.1 Indemnification by GEMS. GEMS agrees to indemnify,
                       ------------------------
defend, and hold R2 and its directors, officers, employees, representatives and
agents harmless from and against any and all third party claims (including those
for personal injury or death), losses, damages, obligations, liabilities and
costs (including reasonable attorneys' and other professional fees and other
costs of litigation) arising out of or attributable to: (a) the operation of the
GEMS Product, including without limitation, any liabilities attributable to a
design defect, malfunction or other failure of the GEMS Product to perform, but
only to the extent that any such liability is not attributable to the operation,
defect, malfunction or failure to operate of the R2 Product; (b) the gross
negligence or willful misconduct of GEMS in connection with this Agreement; or
(c) any breach of this Agreement by GEMS.

                  16.2 Indemnification by R2. R2 agrees to indemnify, defend,
                       ----------------------
and hold GEMS and its directors, officers, employees, representatives and agents
harmless from and against any and all claims (including those for personal
injury or death), losses, damages, obligations, liabilities and costs (including
reasonable attorneys' and other professional fees and other costs of litigation)
arising out of or attributable to: (a) the operation of the R2 Product,
including without limitation, any liabilities attributable to a design defect,
malfunction, the failure of the R2 Product to perform in accordance with
Specifications, or other failure of the R2 Product to perform, but only to the
extent that any such liability is not attributable to the operation, defect,
malfunction or failure to operate of the GEMS Product; (b) the gross negligence
or willful misconduct of R2 in connection with this Agreement; or (c) any breach
of this Agreement by R2.

                  16.3 Indemnification Procedures. In the event that any person
                       ---------------------------
intends to claim indemnification pursuant to Section 16.1 or 16.2 (an
"Indemnitee") it shall promptly notify the indemnifying party (the "Indemnitor")
in writing of such alleged liability, provided that the failure to promptly
notify the Indemnitor shall not relieve the Indemnitor of any obligation under
this Agreement except to the extent such failure to provide prompt notice
adversely impairs the Indemnitor's ability to defend against the claim, suit or
proceeding. The Indemnitor shall have the sole right to control the defense and
settlement thereof, provided, that (a) the Indemnitor may not consent to
imposition of any obligation or restriction on the Indemnitee in any settlement
unless mutually agreed among R2 and GEMS, (b) Indemnitor shall keep Indemnitee
fully informed and permit the Indemnitee to participate (at Indemnitee's
expense) as the Indemnitee may reasonably request and (c) Indemnitee may,
without affecting its right to indemnity hereunder, defend and settle any such
claim, suit or proceeding if Indemnitor declines to defend against such claim,
suit or proceeding or Files for Bankruptcy. The Indemnitees shall cooperate with
the indemnifying party and its legal representatives in the investigation of any
action, claim or liability covered by Section 16.1 or Section 16.2. The
Indemnitee shall not, except at its own cost, voluntarily make any payment or
incur any expense with respect to any claim or suit without the prior written
consent of Indemnitor, which Indemnitor shall not be required to give, provided
that the Indemnitee may, without affecting its right to indemnity hereunder,
defend and settle any such claim, suit or proceeding if the Indemnitor declines
to take responsibility or Files for Bankruptcy.

                       -----------
16.2 above, R2 assumes no liability for (a) any infringement claims with respect

reasonably be brought against the R2 Product standing alone; (b) any trademark
infringement involving any marking or branding not applied by R2 or involving
any marking or branding applied at the request of GEMS; (c) the modification of
the R2 Products, causing the infringement or any part thereof, unless such
modification is made by R2 or pursuant to R2's written direction or consent; or
(d) any infringement resulting solely from R2's compliance with GEMS's
specifications. Notwithstanding the provisions of Subsection 16.1 above, GEMS
assumes no liability for (a) any infringement claims with respect to any product

per occurrence and in the aggregate with the self-insured retention of $10,000
per occurrence and $50,000 aggregate, and that before the first R2 is shipped to
GEMS, R2 will increase this limit to $5,000,000 combined single limit per
occurrence and in the aggregate with the self-insured retention of $10,000 per
occurrence and $50,000 aggregate (the "Insurance Policy"). During the Term, R2
agrees to maintain the Insurance Policy and to take such steps necessary to
provide for GEMS to be named as an additional insured party under the Insurance
Policy. At GEMS' reasonable request, R2 will deliver to GEMS a certificate of

"Confidential," "Proprietary" or some similar designation. Information
communicated orally will be considered Confidential Information if such
information is confirmed in writing as being Confidential Information within a
reasonable time after the initial disclosure. Confidential Information may also
include information disclosed to Sublicensee by third parties. Confidential
information will not, however, include any information which (i) was publicly
known and made generally available in the public domain prior to the time of
disclosure by GEMS; (ii) becomes publicly known and made generally available
after disclosure by GEMS to Sublicensee through no action or inaction of
Sublicensee; (iii) is already in the possession of Sublicensee at the time of
disclosure by GEMS as shown by Sublicensee's files and records immediately prior
to the time of disclosure; (iv) is obtained by Sublicensee from a third party
without a breach of such third party's obligations of confidentiality, (v) is
independently developed by Sublicensee without use of or reference to GEMS'
Confidential Information, as shown by documents and other competent evidence in
Sublicensee's possession; or (vi) is required by law to be disclosed by
Sublicensee, provided that Sublicensee gives GEMS prompt written notice of such
requirement prior to such disclosure and assistance in obtaining an order
protecting the information from public disclosure. The confidentiality
provisions of this Section 5 shall be in addition to the term of any other
confidentiality agreement between GEMS and Sublicensee.

5.2 Non-Use and Non-Disclosure. Sublicensee agrees not to use any Confidential
Information of GEMS for any purpose except to exercise its rights and perform
its obligations under this Software License. Sublicensee agrees not to disclose
any Confidential Information of GEMS to third parties or to Sublicensee's
employees, except to those employees of Sublicensee with a need to know.

software or other tangible objects which embody GEMS' Confidential Information
and which are provided to Sublicensee hereunder.

5.3 Maintenance of Confidentiality. Sublicensee agrees that it shall take
reasonable measures to protect the secrecy of and avoid disclosure and
unauthorized use of the Confidential Information of GEMS. Without limiting the
foregoing, Sublicense shall take at least those measures that it takes to
protect its own most highly confidential information and shall ensure that its
employees who have access to Confidential Information of GEMS have signed a
non-use and non-disclosure agreement in content similar to the provisions
hereof, prior to any disclosure of Confidential Information to such employees.
Sublicensee shall not make any copies of the Confidential Information of GEMS
unless the same are previously approved in writing by GEMS. Sublicensee shall
reproduce GEMS' and Licensor's proprietary rights notices on any such approved


                                       3

GEMS gives Sublicensee written notice of such nonpayment; or

         (b) Sublicensee is in material breach of any nonmonetary term,
condition or provision of this Software License, which breach, if capable of
being cured, is not cured within 30 days after GEMS gives Sublicensee written
notice of such breach; or

any bankruptcy or insolvency proceeding under federal or state statutes; or

6.3 If any Termination Event occurs, termination will become effective
immediately or on the date set forth in the written notice of termination.

Sublicensee's or GEMS' treatment of Confidential Information, provisions
relating to the payment of amounts due, or provisions limiting or disclaiming
GEMS' and/or Licensor's liability, which provisions will survive termination of
this Software License Agreement.

6.4 Upon request, no later than 30 days after the date of termination or
discontinuance of this Software License for any reason whatsoever, Sublicensee
shall return the Software and all copies, in whole or in part, all Documentation

representations or warranty concerning the Software. Any written representation
or warranty not expressly contained in this Software License will not be
enforceable.

expiration or termination of this Software License.

7.7 Force Majeure. Neither party will incur any liability to the other party on
account of any loss or damage resulting from any delay or failure to perform all
or any part of this Software License if such delay or failure is caused, in
whole or in part, by events, occurrences, or causes beyond the control and
without negligence of the parties. Such events, occurrences, or causes will
include, without limitation, acts of God, strikes, lockouts, riots, acts of war,
earthquake, fire and explosions, but the inability to meet financial obligations
is expressly excluded.

party's rights or remedies under this Software License must be in writing to be
effective. Failure, neglect, or delay by a party to enforce the provisions of
this Software License or its rights or remedies at any time, will not be
construed and will not be deemed to be a waiver of such party's rights under
this Software License and will not in any way affect the validity of the whole
or any part of this Software License or prejudice such party's right to take
subsequent action. No exercise or enforcement by either party of any right or
remedy under this Software License will preclude the enforcement by such party
of any other right or remedy under this Software License or that such party is
entitled by law to enforce.

7.9 Severability. If any term, condition, or provision in this Software License
is found to be invalid, unlawful or unenforceable to any extent, the parties
shall endeavor in good faith to agree to such amendments that will preserve, as
far as possible, the intentions expressed in this Software License. If the
parties fail to agree on such an amendment, such invalid term, condition or
provision will be severed from the remaining terms, conditions and provisions,
which will continue to be valid and enforceable to the fullest extent permitted
by law.

7.10 Integration. This Software License (including the Exhibits and any addenda
hereto signed by both parties) contains the entire agreement of the parties with

Software License may not be amended, except by a writing signed by both parties.

7.11 Purchase Orders. No terms, provisions or conditions of any purchase order,
acknowledgement or other business form that Sublicensee may use in connection
with the acquisition or licensing of the Software will have any effect on the
rights, duties or obligations of the parties under, or otherwise modify, this
Software License, regardless of any failure of GEMS or Licensor to object to
such terms, provisions or conditions.

7.12 Publicity. Sublicensee acknowledges that GEMS may desire to use its name in
press releases, product brochures and financial reports indicating that
Sublicensee is a Sublicensee of GEMS, and Sublicensee agrees that GEMS may use
its name in such a manner, subject to Sublicensee's consent, which consent will
not be unreasonably withheld.

7.13 Counterparts. This Software License may be executed in counterparts, each

         GEMS and R2 agree to review and evaluate each potential complaint to
determine whether the information reported constitutes a complaint within the
meaning of 21 C.F.R. ss. 820.3(b), and whether it merits investigation. GEMS and
R2 shall confer to determine whether a complaint investigation is required, and
GEMS and R2 shall each establish a record justifying its rationale for not
investigating any complaint. If GEMS and R2 are unable to reach an agreement
regarding whether to conduct an investigation, both parties will discuss the
issue with FDA simultaneously to determine whether an investigation is
warranted. If FDA determines than an investigation is warranted, both parties
will conduct an investigation. If FDA determines that an investigation is not
warranted, neither party will conduct an investigation.

         Where an investigation is warranted, each party shall be responsible
for investigation of the complaint. Such investigation shall be conducted at
each party's expense. GEMS and R2 shall each establish and maintain a program,
as required by 21 C.F.R. ss. 820.198, to ensure that (a) each complaint is
adequately reviewed, evaluated, and maintained; (b) any complaint involving the
possible failure of a device to meet any of its performance specifications is
adequately investigated; and (c) any complaint pertaining to safety is
immediately reviewed, evaluated, and investigated. To the extent that GEMS
requires additional information to enable it to perform the complaint
investigation, GEMS shall notify R2 and R2 shall cooperate fully in assisting
GEMS with the conduct of the investigation, excluding information pertaining to
the R2 product algorithm. To the extent that R2 requires additional information
to enable it to perform the complaint investigation, R2 shall notify GEMS and

a recall, market withdrawal, or other corrective action is required, both
parties shall discuss the issue with FDA simultaneously to determine whether a
recall, market withdrawal, or other corrective action is required. If FDA
determines that a recall, market withdrawal, or other corrective action is
required, the party whose act or omission, according to FDA, gave rise to the
recall, market withdrawal, or other corrective action (the recalling or
initiating party) shall use its best efforts to promptly correct the problem(s)
that caused the recall, market withdrawal, or other corrective action and shall
be responsible for the recall, market withdrawal, or other corrective action.
The parties agree that the recalling or initiating party shall be the point of
contact for purchasers in the event of a corrective action, and the recalling or
initiating party shall be responsible for all communications with customers. The
recalling or initiating party will maintain complete and accurate records, for
such periods as may be required by applicable law, related to any recall, market
withdrawal, or other corrective action. The recalling or initiating party shall

risk of loss or damage to the R2 Product for the shipment to R2, within a
reasonable period of time of discovering the failure and after first receiving a
Return Material Authorization from R2, which shall not be unreasonably withheld.
No later than 15 calendar days after R2's receipt of rejected R2 Product, R2
shall, at its option and expense if within the Warranty Period, or at GEMS's
option and expense as quoted by R2 outside of the Warranty Period, either repair
or replace said R2 Product. R2 shall bear all expense and risk of loss or damage
to R2 Product for the return shipment to GEMS. R2 Product not rejected within 15
