ITEM 5.   OTHER EVENTS.

     On June 4, 1998 a definitive settlement agreement was entered into between
and among Summit Technology, Inc. ("Summit"), Summit Partner, Inc., the
Registrant, VISX Partner, Inc. and Pillar Point Partners ("Pillar Point"). All
parties agreed to dissolve Pillar Point, the partnership formed between them to
bring laser vision correction to its current status as a safe and effective
alternative to glasses and contact lenses. Registrant and Summit also agreed to
end all pending disputes and litigation between the two companies. Under the
settlement, Registrant and Summit will each retain their respective rights to
license other manufacturers to their own patents and have granted to each other
a worldwide, royalty free cross license. In addition, each party will have full
rights to license its laser system users to all patents owned by either company
relating to laser ablation of corneal tissue including all patents presently
included, or includable, in Pillar Point. The settlement requires a payment by
Registrant to Summit of $35 million.

                      SETTLEMENT AND DISSOLUTION AGREEMENT

     This Settlement and Dissolution Agreement is made and entered into this
4th day of June, 1998 (the "Effective Date"), between and among Summit
Technology, Inc., a corporation organized under the laws of the Commonwealth of
Massachusetts ("Summit"), Summit Partner, Inc., a corporation organized under
the laws of the State of Delaware ("SPI"), VISX, Incorporated, a corporation
organized under the laws of the State of Delaware ("VISX"), VISX Partner, Inc.,
a corporation organized under the laws of the State of Delaware ("VPI") and
Pillar Point Partners, a Delaware general partnership whose general partners
are SPI and VPI ("Pillar Point").

                              W I T N E S S E T H:

     WHEREAS, Summit and VISX caused Pillar Point to be formed in 1992 to
resolve certain patent disputes and, in connection therewith, entered into a
Formation Agreement dated June 3, 1992 ("Formation Agreement") and caused their
affiliates SPI and VPI to enter into a Partnership Agreement of even date
("Partnership Agreement"); and

     WHEREAS, in accordance with the provisions of the Formation Agreement and
the Partnership Agreement, Summit and VISX, through SPI and VPI, each caused to
be contributed to Pillar Point the exclusive licensing rights in and to certain
of their patents containing claims covering methods and apparatus for
performing ultraviolet laser corneal surgery in the United States and agreed
automatically to contribute to Pillar Point similar rights in any subsequently
issued patents under any U.S. patent application having a filing or priority
date in whole or in part occurring on or before June 3, 1993, as well as rights
in certain Precluding Patents (as defined in the Formation Agreement); and

     WHEREAS, Summit and VISX each entered into License Back Agreements with
Pillar Point ("License Back Agreements"), pursuant to which Pillar Point
granted to each a non-exclusive license to the Pillar Point certain patents
(the License Back, Formation and Partnership Agreements, together with all
amendments thereto and the collateral documentation executed and delivered in
connection therewith, are hereinafter collectively referred to as the "Pillar
Point Agreements"); and

     WHEREAS, on June 17, 1997, Summit and VISX entered into a settlement
agreement (the "Azema Settlement Agreement"), pursuant to which the parties
resolved certain patent disputes, released various claims, cross licensed
certain of each other's foreign patents, covenanted not to sue each other for
patent infringement, and caused the exclusive licensing rights to Summit's
United States Azema Patents (as defined in the Azema Settlement Agreement) to
be contributed to Pillar Point; and

     WHEREAS, Pillar Point, Summit and VISX are involved in numerous disputes
between and among themselves and with third parties relating to Pillar Point;
and

     WHEREAS, Summit and VISX desire to reach a final and complete settlement
of all claims, disputes and lawsuits between them, dissolve Pillar Point, cross
license patents and

   2
exchange general releases, all in accordance with the terms and conditions of
this Settlement and Dissolution Agreement;

     NOW, THEREFORE, in consideration of the payments, releases, licenses,
covenants and undertakings hereinafter set forth, Pillar Point, Summit and VISX
agree as follows:

                               A G R E E M E N T:

     1.   Affiliates. For purposes of this Settlement and Dissolution
Agreement, the term "Affiliate" means (a) any corporation, entity or person
that now or in the future owns or acquires at least 85% of the shares entitled
to vote of Summit or VISX or that otherwise acquires Summit or VISX by merger,
consolidation, or acquisition of substantially all of the assets of Summit or
VISX or (b) any corporation, entity or person with respect to which, now or in
the future, Summit or VISX owns or acquires at least 85% of the shares entitled
to vote of such corporation, entity or person or that is otherwise acquired by
Summit or VISX by merger, consolidation or acquisition of substantially all of
the assets of such corporation, person or entity. Under no circumstances shall
a cooperative venture (as defined at Section 11, below) be deemed to qualify a
third party as an Affiliate of VISX or Summit, absent compliance with the
specific provisions of this Section 1. Hereinafter, references to Summit and
VISX in this Settlement and Dissolution Agreement (including, for example,
references to cross licenses granted between Summit and VISX) shall be deemed
to include their respective Affiliates.

     2.   Patents. (a) For purposes of this Settlement and Dissolution
Agreement, the term "Summit Patents" means all U.S. and foreign patents issued
to Summit or in which Summit in the future acquires an ownership interest or
the right to license others to practice the art embodied in the patent, and
which relate to a method or apparatus for laser ablation of corneal tissue. (b)
For purposes of this Settlement and Dissolution Agreement, the term "VISX
Patents" means all U.S. and foreign patents issued to VISX or in which VISX in
the future acquires an ownership interest or the right to license others to
practice the art embodied in the patent, and which relate to a method or
apparatus for laser ablation of corneal tissue. Without limitation, the Summit
Patents and the VISX Patents include all of the Patents included or includable
in Pillar Point by virtue of the Pillar Point Agreements.

     3.   Payment. In consideration for the settlement of litigation and
releases described in Sections 8, 12 and 14, below, within one (1) business day
of the Effective Date, VISX shall make a single lump sum cash payment to Summit
in the amount of Thirty-Five Million Dollars ($35,000,000), in good,
immediately available funds, wired to the following account: BankBoston,
Account #551-06959, ABA #011000390, 100 Federal Street, Boston, Massachusetts
02110 (or such other account as Summit may direct). In the event VISX fails to
timely make the payment described in this Section 3, Summit shall have the
option of either (i) terminating this Agreement and treating it as null and
void or (ii) treating the Agreement as effective and suing VISX in the United
States District Court for the District of Massachusetts or any other court of
competent jurisdiction for breach of contract and/or to specifically enforce
VISX's payment and other


                                       2
   3
obligations hereunder. In the event of such suit, VISX (i) consents to the
jurisdiction and venue selected by Summit and (ii) shall be liable for all of
Summit's costs of suit, including attorneys' fees.

     4.   Royalty-Free License to VISX. Pillar Point hereby grants to VISX an
irrevocable, perpetual, non-exclusive, non-transferable, fully paid up license
under the Summit Patents to make, have made, use, offer to sell, sell, lease
and otherwise dispose of products that come within the claims of the Summit
Patents, whether directly or indirectly through distributors or other
resellers, and to perform and sublicense others to perform procedures using
those products or which are covered by method claims of the Summit Patents, in
the United States.

     5.   Royalty-Free License to Summit. Pillar Point hereby grants to Summit
an irrevocable, perpetual, non-exclusive, non-transferable, fully paid up
license under the VISX Patents, to make, have made, use, offer to sell, sell,
lease and otherwise dispose of products that come within the claims of the VISX
Patents, whether directly or indirectly through distributors or other
resellers, and to perform and sublicense others to perform procedures using
those products or which are covered by method claims of the VISX Patents, in
the United States.

     6.   Dissolution of Pillar Point. Effective immediately following the
grant of the licenses described in Sections 4 and 5, above ("Payment Date"),
Pillar Point is hereby dissolved, and, subject only to the terms of this
Agreement, the Pillar Point Agreements are terminated and all rights to
license, prosecute, defend and otherwise deal in and with the VISX Patents
shall revert back to VISX or its designee (subject to, among other terms of
this Agreement, the terms of Section 5, above), and all rights to license,
prosecute, defend and otherwise deal in and with the Summit Patents shall
revert back to Summit or its designee (subject to, among other terms of this
Agreement, the terms of Section 4 above). From and after the Payment Date,
neither Summit nor VISX shall have any further payment or other obligation to
Pillar Point in respect of equipment royalties, procedure royalties, or
otherwise.

     7.   Winding Up and Termination of Pillar Point. Notwithstanding the
provisions of Section 6, above, Pillar Point shall remain in existence after
the Payment Date for the sole purpose of winding up its affairs, defending or
settling remaining litigation in which it is or becomes a defendant and/or
completing the defense of any such litigation. Except as specifically set forth
below, liability for costs and expenses incurred by Pillar Point prior to
dissolution, and for ongoing expenses of Pillar Point incurred in connection
with the winding up activities described above, shall be allocated 60% to VISX
and 40% to Summit. Rights to remaining Pillar Point assets, including cash,
claims against third parties (such as patent infringement) and receivables held
by Pillar Point which accrued prior to the Payment Date or which otherwise
remain in Pillar Point after winding up, shall be allocated 60% to VISX and 40%
to Summit. Until the Payment Date, the License Back Agreements will remain in
force and the parties will remain liable for royalties to Pillar Point accruing
prior thereto, provided that each party may calculate royalties using the same
assumptions and contract interpretations as were used in the immediately prior
month.

               VISX

      It is the intent of the parties that the Joint Defense Agreement among
them relating to the Third Party Litigation shall survive execution of this
Settlement Agreement. This Settlement and Dissolution Agreement may not be
varied or modified other than by a writing executed on behalf of each of the
parties hereto. With the exception of transfers of rights to present or future
Affiliates (which occurs without necessity of further action), neither VISX nor
Summit shall assign, transfer, or delegate any of its rights, duties and
obligations under this Settlement and Dissolution Agreement without the
express written consent of the other party, which consent shall not be
unreasonably withheld.

      22.   Strict Performance. The failure by any party to insist upon the
strict performance of any covenant, duty, agreement or condition of this
Settlement and Dissolution Agreement or to exercise any right or remedy
consequent upon a breach thereof shall not constitute waiver of any such breach
or any other covenant, duty, agreement or condition.

      23.   Indemnification. Each of Summit and VISX (for purposes of this
Paragraph 23, each a "Licensee") shall indemnify, defend and hold harmless the
other party and its successors and assigns (for purposes of this Paragraph 23,
each a "Licensor") from and against any loss, damage, cost or expense of
whatsoever kind or nature (including reasonable attorneys' fees and
professional expenses) incurred by the Licensor by reason of any product
liability claim arising out of the manufacture, use, sale, lease, license or
other disposition of products manufactured or marketed by Licensee or any
Licensee Affiliate or any distributor of Licensee or any Licensee Affiliate and
licensed hereunder. The foregoing indemnification and agreement to defend and
hold harmless shall include, without limitation, any cost or expense incurred
or to be incurred by the Licensor or any Licensor Affiliate by reason of its
having been or being made a party or being threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,


                                       11
   12
criminal, administrative or investigative in connection with any actual or
alleged act or omission in connection with any such manufacture, use, sale,
lease, license or other disposition of products manufactured or assembled by
Licensee or any Licensee Affiliate or performance of any procedures using those
products. The foregoing indemnification and agreement to defend and hold
harmless shall not extend to any acts or omissions by or on behalf of the
Licensor or its Affiliates in bad faith or as a result of negligence. A party
claiming indemnification shall not be entitled to indemnification with respect
to any action to which it consented in writing or any claim as to which it did
not give written notice to the party from which indemnification is sought
within ninety (90) days after having received notice of such claim. IN NO EVENT
SHALL EITHER PARTY BE LIABLE TO THE OTHER FOR ANY INCIDENTAL, PUNITIVE, SPECIAL
OR CONSEQUENTIAL DAMAGES. In the event any claim for indemnification arises
from a claim of a third party, the party from whom indemnification is sought
shall have the right to defend against such third party claim and, in such
event, the party seeking indemnification shall cooperate with all reasonable
requests in the defense thereof at the expense of the party from whom
indemnification is sought.

      24.   No Agency. Nothing in this Settlement Agreement shall be deemed to
appoint or authorize any party to act as an agent of the other party or to
assume or incur any liability or obligation in the name or on behalf of the
other party.

      25.   Labels. (a) VISX shall affix to each product covered by one or more
of the Summit Patents that is sold, licensed, leased or otherwise disposed of
after the Effective Date a label reasonably requested by Summit listing the
applicable Summit Patent(s). The purpose of the label is to provide notice of
the Summit Patents to other parties to establish or support a claim by Summit
against any such other party of damages due to infringement. Summit and VISX
agree that any such label will not be introduced into evidence, produced, relied
upon, or used in any way in any proceeding between Summit and VISX, except in a
proceeding related to enforcement of the terms of this Settlement and
Dissolution Agreement; (b) Summit shall affix to each product covered by one or
more of the VISX Patents that is sold, licensed, leased or otherwise disposed of
after the Effective Date a label reasonably requested by VISX listing the
applicable VISX Patent(s). The purpose of the label is to provide notice of the
VISX Patents to other parties to establish or support a claim by VISX against
any such other party of damages due to infringement. Summit and VISX agree that
any such label will not be introduced into evidence, produced, relied upon, or
used in any way in any proceeding between Summit and VISX, except in a
proceeding related to enforcement of the terms of this Settlement and
Dissolution Agreement.

      26.   Governing Law. This Settlement and Dissolution Agreement shall be
governed by the laws of the State of Delaware. The terms of this Settlement and
Dissolution Agreement may be enforced in any court of competent jurisdiction.
Both parties hereby acknowledge and submit to the jurisdiction of the Federal
District Court for the District of Delaware to hear and resolve any dispute
over terms of the Settlement and Dissolution Agreement, to protect and enforce
the parties' rights hereunder, to rectify the contract if necessary, and to
order specific performance, injunction or similar equitable relief.

     27.  Counterparts. This Settlement and Dissolution Agreement may be
executed in separate counterparts, each of which shall be considered an
original but all of which shall constitute one agreement.

     28.  Public Statements. Summit and VISX agree that neither of them shall
make any public statements about this Settlement and Dissolution Agreement or
its terms, except as may be set forth in the joint press release referred to
below or as required by applicable securities laws. VISX and Summit shall be
permitted to disclose the terms of this Settlement and Dissolution Agreement to
the Federal Trade Commission, and to any other person or entity if ordered to
do so by a court of competent jurisdiction, and VISX and Summit shall be
permitted to issue a joint press release, after the Effective Date, announcing
the fact that they have settled outstanding disputes and agreed to dissolve
Pillar Point Partners and the general terms of the Agreement.

     WHEREFORE, the parties hereto, having been duly authorized to do so, have
caused this Settlement and Dissolution Agreement to be executed as of the date
first above written.
