right to inspect Licensee's facilities during normal business hours, without
prior advance notice, to confirm that Licensee's use of such trademarks and
service marks is in compliance with this Section 2.2.

     2.3  TRANSFER OF INFORMATION. As soon as practicable after the Effective

     2.4  NO RIGHTS BY IMPLICATION. No rights or licenses with respect to
Licensed Technology or the Implantable Medical Devices are granted or deemed
granted hereunder or in connection herewith, other than those rights or licenses
expressly granted in this Agreement.

     2.5  NO WARRANTY. EXCEPT AS SET FORTH IN SECTION 2.6, LICENSEE ACKNOWLEDGES
THAT IT RECEIVES THE LICENSED TECHNOLOGY ON AN "AS IS" BASIS. THERE IS NO
WARRANTY OF LICENSOR IN THIS AGREEMENT CONCERNING THE LICENSED TECHNOLOGY OR THE

IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE.

     2.6  REPRESENTATIONS AND WARRANTIES.

          (A)  Licensor hereby represents and warrants that:

               (1) Licensor has full power and authority to execute, deliver and
perform this Agreement.

               (2) This Agreement has been duly executed and delivered by
Licensor and constitutes the valid and binding obligation of Licensor,
enforceable against Licensor in accordance with its terms, except as limited by
principles of equity and applicable bankruptcy, insolvency, and other laws of
general applicability affecting the enforcement of creditors' rights.

               (3) Licensor represents and warrants that it is the owner of the
entire right, title, and interest in and to Licensed Technology, except for a
joint ownership interest of Thermedics, Inc., a Massachusetts corporation,
having offices at 470 Wildwood Street, Woburn, MA 01888, with Licensor in and to
U.S. Patent No. 5,254,662 and its related patents and applications in Australia,
Canada, the EPO, and WO, as set forth in Exhibit A

                                       -3-

hereto as "Joint Patents and Patent Applications." To the best of Licensor's
knowledge and except set forth in this Section 2.6 (c), the Licensed Technology
is free and clear of any lien or similar encumbrance.

               (4) The Licensor represents and warrants that it has the right to
grant the exclusive right in Section 2.1, without requiring the consent or
approval of any third party to this Agreement, with regard to Licensor's entire
right, title, and interest in and to the Licensed Technology. In the event that,
as a result of Thermedics, Inc.'s joint ownership in the patents and patent
applications set forth in Exhibit A as "Joint Patents and Patent Applications,"
in the written opinion of patent counsel for Licensee, the consent of
Thermedics, Inc. is required by the law of a foreign country for the grant of
the license set forth herein, Licensor will use its best efforts to obtain such
consent. If such consent is not granted by Thermedics, Inc. in writing within
sixty (60) days after the date of Licensee's request for such consent, then, at
the request of Licensee, Licensor will execute and deliver to Licensee an
assignment, in mutual satisfactory form, conveying to Licensee an undivided
joint interest in and to Licensor's joint ownership of the right, title and
interest in and to the specific patent or patent application of the "Joint
Patents and Patent Applications" in Exhibit A for which Thermedics, Inc. did not
grant its consent. If such an assignment is granted, the result will be that the
specific patent or patent application of the "Joint Patents and Patent
Applications" in Exhibit A will be jointly owned by Licensor, Licensee and
Thermedics, Inc. in the foreign country at issue.

               (5) Licensor represents and warrants that the execution and
delivery of this Agreement is not inconsistent with any prior agreements or
instruments regarding Licensed Technology to which the Licensor is bound.

          (B) Licensee hereby represents and warrants that:

               (1) Licensee has full power and authority to execute, deliver and
perform this Agreement.

               (2) This Agreement has been duly executed and delivered by
Licensee and constitutes the valid and binding obligation of Licensee, and its
successors and assigns, enforceable against Licensee, and its successors and
assigns, in accordance with its terms, except as limited by principles of equity
and applicable bankruptcy, insolvency, and other laws of general applicability
affecting the enforcement of creditors' rights.

               (3) Licensee represents and warrants that the execution and
delivery of this Agreement is not inconsistent with any prior agreements or
instruments regarding Licensed Technology to which the Licensee is bound.

own use and benefit.

          (c) Licensor may agree to any settlement of any such action brought
under Section 4.1(b), at its own discretion, without the prior consent of

by third parties of products which are not Implantable Medical Devices.

     4.2  USE OF NAME IN SUIT. When, in the reasonable judgment of Licensor, it
is necessary to use Licensee's name to prosecute or defend an action pursuant to
Section 4.1 hereof, Licensee agrees to allow Licensor to so use its name; and
when, in the judgment of Licensee, it is necessary to use Licensor's name to
prosecute or defend an action pursuant to Section 4.1 hereof, Licensor agrees to
allow Licensee to use its name.

     4.3 NOTIFICATION OF SUIT BY LICENSEE. Licensee shall notify Licensor in

          (a) Licensee hereby acknowledges that each and every part of the
Licensed Technology on the Effective Date and any addition to the Licensed
Technology by Licensor during the term of this Agreement is either: (i) the

useful in Licensor's opinion to prove, apply for, secure, maintain, reissue,
extend or defend Licensor's world-wide rights in the rights described in Section
5.1(a) above. Without limiting the foregoing, Licensee shall enter into such
user agreements with Licensor as necessary to secure Licensor's ownership rights
described in Section 5.1(a), in forms mutually agreed upon by Licensor and
Licensee.

          (c) Licensee warrants and represents to Licensor that Licensee, and to
