                                                | Licensed Procedure
------------------------------------------------|-------------------------------

A.       WHO MAY USE THE SYSTEM?
         -----------------------

Authorized Users. Licensee and the individuals designated above (the "Authorized
------------------
Users") are the only persons permitted to use the System. Licensee shall permit
only eye care practitioners who have experience in the surgical management and
treatment of the cornea and who are legally qualified, properly licensed and
fully trained and certified by VISX (or its designees) to perform Licensed
Procedures (as defined below) on the System. Licensee will provide VISX at least
10 days prior written notice of any change in the designated Authorized Users.
Licensee represents, warrants and covenants that it is and its Authorized Users
are, and will remain for so long as Licensee is using the System, fully licensed
and legally qualified and certified by VISX to perform the specific Licensed
Procedure to be performed, and that Licensee and its Authorized Users shall
remain trained in the proper techniques for performing that Licensed Procedure
in the most effective and safe manner. Licensee shall notify VISX promptly of
any exception to the foregoing representation, warranty and covenant.

B.       INTELLECTUAL PROPERTY RIGHTS
         ----------------------------

1.   Patents.   The  System,   the  VisionKey  (R)  card,  and  certain  related
     -------
     disposables, and their use, are covered by several United States patents
     for which VISX has the authority to provide this License. A list of these
     patents is set forth in Schedule A (the "Patents"). The Patents cover
     apparatus and methods for performing ophthalmic laser surgery. Use of the
     System to perform any procedure covered by the Patents is prohibited unless

                                        1

<PAGE>

     such use is authorized by a valid VISX Patent License. The sale, lease or
     other transfer of the System by VISX or any other person or entity does not
     in any way grant a license under any Patent to use the System to perform
     any procedures. Such license may only be granted by the delivery to VISX of
     a fully-executed VISX Patent License.

2.   Ownership of Intellectual  Property Rights. VISX owns all right, title, and
     ------------------------------------------
     interest in the VisionKey cards, and in all of VISX's patents, trademarks,
     trade names, inventions, copyrights, know-how, and trade secrets relating
     to the design, use, manufacture, operation or service of the System and
     relating to performance of Licensed Procedures. The use by Licensee of any
     of these intellectual property rights is permitted only for the purposes
     authorized in this License and only in connection with use of the System,
     and upon termination of this License for any reason such authorization
     shall cease. Licensee recognizes that performance of the Licensed
     Procedures without payment of the License Fee constitutes infringement of
     VISX's intellectual property rights.

C.       GRANT
         -----

1.   License  Grant.  Subject to  Licensee's  compliance  with the terms of this
     --------------
     License. VISX continuations, continuations-in-part, divisional patents,
     reexaminations, renewals, hereby grants to Licensee the right and license
     under the Patents (including any extensions and reissues of such Patents)
     to perform, and permit Authorized Users to perform, any ultraviolet laser
     corneal surgery procedure using the System and related disposables, which
     performance or use is covered by at least one claim of a Patent (a
     "Licensed Procedure") at the Site. Upon breach by Licensee of any of its
     obligations contained in this License, the license granted hereby shall be
     revoked and VISX shall have the right, without notice or demand, to disable
     or take possession of the System. This License is limited to the
     performance of Licensed Procedures using the System.

2.   Consideration.  In consideration  for the license granted under the Patents
     -------------
     pursuant to Section C.1, Licensee shall pay the License Fee listed on the
     front page of this License each time the System is used to perform a
     Licensed Procedure, except that the License Fee shall be $-0- each time the
     System is used to perform a phototherapeutic keratectomy (PTK). For
     convenience of the parties, payment of the License Fee is due upon shipment
     of each VisionKey card and payable on the terms set forth in the Sales or
     Lease Agreement. The License Fee does not include the cost of the card.

3.   Tampering.  Licensee is  prohibited  from  tampering  with or attempting to
     ---------
     reverse engineer the VisionKey card or any device or software installed on
     the System for the purpose of monitoring the number of Licensed Procedures
     performed. MODIFYING OR ALTERING THE SYSTEM, THE VISIONKEY CARD OR THE CARD
     READING MECHANISM IN ANY WAY CONSTITUTES WILLFUL INFRINGEMENT OF THE
     INTELLECTUAL PROPERTY LICENSED UNDER THIS LICENSE AND MAY ENDANGER PATIENT

                                        2

<PAGE>
     SAFETY. ANY SUCH MIDIFICATIONOR ALTERATION WILL RENDER THE SYSTEM
     ADULTERATED UNDER THE FEDERAL FOOD, DRUG AND COSMETIC ACT AND COULD SUBJECT
     THE LICENSEE AND/OR THE AUTHORIZED USERS TO ACTION BY THE FDA RESULTING IN
     SEIZURE, INJUNCTION, CIVIL PENALTIES, AND/OR CRIMINAL PROSECUTION.

4.   Term and  Termination.  This License will continue  until the expiration of
     ---------------------
     the last of the Patents to expire and Licensee's obligation to pay the
     License Fee shall terminate for a given procedure on the expiration of the
     last of the Patents containing one or more claims which cover use of the
     System or performance of such procedure. This License may be terminated at
     any time by VISX if (a) Licensee fails to make any payment due under this
     License within 30 days of the due date, (b) Licensee has tampered in any
     way with the VisionKey card or the card reading mechanism, the software
     installed in the System, or any other part of the System, or (c) Licensee
     fails to cure any other breach of this License within 30 days after VISX
     provides written notice of such breach to Licensee. Upon any early
     termination, Licensee and all Authorized Users shall cease all use of the
     System. Licensee understands that the security interest in the system
     granted to VISX in the Sales or Lease secures performance of Licensee's
     obligations under this License. The respective rights and obligations of
     VISX and Licensee under the provisions of Sections C.3, C.4, D.2, E.1, E.2,
     and E.4 shall survive any termination of this License.

D.       LOCATION AND CONDITION OF THE SYSTEM

     -------------------------
     Site designated on the first page of this License.

     VISX. Licensee man not sell or otherwise transfer the System unless the
     proposed transferee has entered into the then current form of VISX Patent
     License for the System, at which time this License shall terminate and
     Licensee's rights under this License shall expire. Licensee may not
     transfer or sublicense any of its rights or obligations under this License
     without VISX's prior written consent, except as may be implicit in its
     granting the Authorized Users the privilege to use the System pursuant to
     this License.

3.   Use and Maintenance. Licensee and the Authorized Users shall use the System
     -------------------
     only in accordance with the procedures and other requirements set forth in
     the user's manuals or other documentation accompanying the System or

     be properly maintained in accordance with VISX's service recommendations
     and shall ensure that all Licensed Procedures performed using the System
     are performed in a safe and effective manner. Licensee shall not be
     obligated by this License to retain VISX or any of its affiliates to
     perform maintenance on the System.

                                        3

<PAGE>
4.   Access to System.  Licensee shall allow VISX, at VISX's sole expense,  from

     obtaining the information measured by any device or software installed on
     the System and to monitor Licensee's compliance with the terms of this
     License.

E.       LIABILITY, IMMUNITY, AND COMPLIANCE WITH LAWS
         ---------------------------------------------

1.   Disclaimer  of  Liability.   VISX  SHALL  NOT  BE  LIABLE  FOR  INCIDENTAL,
