                        ARTICLE XII - TERM & TERMINATION

               12.1 Term of Agreement. This Agreement shall be effective as of
the date first set forth hereinabove ( "Effective Date"), and shall continue in
full force and effect for ten (10) years from the date of first NDA or PMA
approval for commercial sale of Co-Developed Devices. Provided that both parties
agree in writing, at least one hundred eighty (180) days prior to the expiration
of the then existing term, PDTI and IRIDEX shall have the option to extend the
term of this Agreement by successive two (2) year periods.

               12.2 Termination for Material Breach. Either party may terminate
this Agreement in the event of a material breach by the other, provided that the
party asserting such breach first serves written notice of the alleged material
breach on the offending party and such alleged breach is not cured within sixty
(60) days of said notice unless such material breach cannot be cured within said
period in which case the cure period will be extended an additional ninety (90)
days if the offending party has taken reasonable steps to cure the material
breach within the sixty (60) day period.

               12.3 Termination for Insolvency. In the event that either party
becomes insolvent or shall suspend its business, or shall file a voluntary
petition or any answer admitting the jurisdiction of the court and the material
allegations of, or shall consent to, an involuntary petition pursuant to or
purporting to be pursuant to any reorganization or insolvency law of any
jurisdiction, or shall make an assignment for the benefit of creditors, or shall
apply for or consent to the appointment of a receiver or trustee of all or a
substantial part of its property (such party, upon the occurrence of any such
event, a "Bankrupt Party"), then to the extent permitted by the law the other
party hereto may thereafter immediately terminate this Agreement by giving
written notice of termination to the Bankrupt Party, unless the proceeding is
dismissed within ninety (90) days of its filing.

               12.4 Effect of Expiration or Termination. Expiration or earlier
termination of this Agreement shall not extinguish rights or obligations
previously accrued or vested. Upon such expiration or earlier termination IRIDEX
may, at its option, liquidate such inventory of Co-Developed Devices as IRIDEX

obligation of IRIDEX to pay royalties on such inventory in accordance with

                         ARTICLE XIII - INDEMNIFICATION

               13.1 PDTI Indemnity. PDTI agrees to indemnify, protect and defend
IRIDEX and hold IRIDEX harmless from and against any claims, damages, liability,
harm, loss, costs, penalties, lawsuits, threats of lawsuit, judgments, recalls
or other governmental action, including reasonable attorneys' fees, brought or
claimed by any third party which (i) arise as the result of PDTI's breach of
this Agreement or of any warranty or representation made by PDTI under this
Agreement or (ii) result from the grossly negligent acts or willful malfeasance
on the part of PDTI or its employees or agents in connection with PDTI's
manufacture, use, sale, marketing or distribution of Co-Developed Devices or
other activities or actions in connection with the Co-Developed Devices; or
(iii) result from any claim made against IRIDEX in connection with PDTI
Technology. Upon the filing of any such legal claim or lawsuit against IRIDEX,
IRIDEX shall promptly notify PDTI, in writing, of any such claim and PDTI shall,
at its expense, with attorneys reasonably acceptable to IRIDEX, handle, defend
and control such claim or lawsuit.

               13.2 IRIDEX Indemnity. IRIDEX agrees to indemnify, protect, and
defend PDTI and hold PDTI harmless from and against any claims, damages,
liabilities, harm, loss, costs, penalties, lawsuits, threats of lawsuit,
judgments, recalls or other governmental action, including reasonable attorneys'
fees, brought or claimed by any third party, which (i) arise as a result of
IRIDEX's breach of this Agreement or of any warranty or representation made by
IRIDEX under this Agreement; or, (ii) result from the grossly negligent acts or
willful malfeasance on the part of IRIDEX or its employees or agents, in
connection with IRIDEX's manufacture, use, sale, marketing or distribution of
Co-Developed Devices or other activities or actions in connection with the
Co-Developed Devices; or (iii) result from any claim made against PDTI in
connection with IRIDEX Technology. Upon the filing of any such legal claim or
lawsuit against PDTI, PDTI shall promptly notify IRIDEX, in writing, of any such
claim IRIDEX shall, at its expense, with attorneys reasonably acceptable to
PDTI, handle, defend, and control such claim or lawsuit.

               13.3 Notice of Defense of Actions. Each party shall give the
other prompt notice of any potential liability, and promptly after receipt by a
party claiming indemnification under this Article XIII, of notice of the
commencement of any action, such indemnified party shall notify the indemnifying
party of the commencement of the action and generally summarize such action. The
indemnifying party shall have the right to participate in and to assume the
defense of such action with counsel of its choosing. An indemnifying party shall
not have the right to direct the defense in such an action of an indemnified
party if counsel to such indemnified party has reasonably concluded that there
may be defenses available to it that are different from or additional to those
available to the indemnifying party; provided, however, that in such event, the
indemnified party shall bear the fees and expenses of separate counsel
reasonably satisfactory to the indemnifying party. The failure to notify an
indemnifying party promptly of the commencement of any such action, if
materially prejudicial to the ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Article
XIII. No settlement of any claim or action may be made without the consent of
the indemnifying party (which consent shall not be unreasonably withheld or
delayed).

incurred by such other party due to strikes, lockouts, accidents, fire, delays
in manufacture, transportation or delivery of material, embargoes, inability to
ship, explosions, floods, war, governmental action or any other cause similar
thereto which is beyond the reasonable control of such other party and any
failure or delay by a party in the performance of any of its obligations under

breach of this Agreement due to, but only so long as there exists, one or more
of the foregoing causes.

               14.2 Relationship. This Agreement shall not be construed to
create between the parties hereto or their respective successors or permitted
assignees the relationship of principal and agent, joint ventures, co-partners
or any other similar relationship, the existence of which is hereby expressly
denied by each party. The parties shall not be liable to any third party in any
way for engagement, obligation, contract, representation or transaction or for
any negligent act or omission to act of the other except as expressly provided.

               14.3 Governing Law. The provisions of this Agreement shall be

               14.5 Legal Construction. In case any one or more of the
provisions contained in this Agreement shall be invalid or unenforceable in any
respect, the validity and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby and the parties will
attempt to agree upon a valid and enforceable provision which shall be a
reasonable substitute for such invalid and unenforceable provision in light of
the tenor of this Agreement, and, upon so agreeing, shall incorporate such
substitute provision in this Agreement.

               14.6 Entire Agreement, Modifications, Consents, Waivers. This
Agreement contains the entire agreement of the parties with respect to the
subject matter hereof. This Agreement may not be modified or amended except by
an instrument or instruments in writing signed by the party against whom
enforcement of any such modification or amendment is sought. Each party hereto
may, by an instrument in writing, waive compliance by another party hereto with

<PAGE>   19
party hereto of a breach of any term or provision of this Agreement shall not be
construed as a waiver of any subsequent breach.

               14.7 Section Headings: Construction. The section headings and
titles contained herein are each for reference only and shall not be deemed to
affect the meaning or interpretation of this agreement. The words "hereby",
"herein", "hereinabove", "hereinafter", "hereof' and "hereunder", when used
anywhere in this Agreement, refer to this Agreement as a whole and not merely to
a subdivision in which such words appear, unless the context otherwise requires.
The singular shall include the plural, the conjunctive shall include the
disjunctive and the masculine gender shall include the feminine and neuter, and
vice versa, unless the context otherwise requires.

               14.8 Execution Counterparts. This Agreement may be executed in
any number of counterparts and each such duplicate counterpart shall constitute
an original, any one of which may be introduced in evidence or used for any
other purpose without the production of its duplicate counterpart. Moreover,
notwithstanding that any of the parties did not execute the same counterpart,
each counterpart shall be deemed for all purposes to be an original, and all
such counterparts shall constitute one and the same instrument, binding on all
of the parties hereto.


                     ARTICLE XV - BINDING EFFECT; ASSIGNMENT

               In entering into this Agreement, each party hereto has relied
upon the expertise and capabilities of the other. Accordingly, the parties may
not directly or indirectly assign, delegate, encumber or in any other manner
transfer any of its rights, remedies, obligations, liabilities or interests in
or arising under this Agreement, without the prior consent of the other, which
consent shall not be unreasonably withheld or delayed, except that either party
(an "Assigning Party") may directly or indirectly assign, delegate, encumber or
in any other manner transfer any of its rights, remedies, obligations,
liabilities or interests in or arising under this Agreement, upon prior notice
to (but without obtaining the prior consent of the other party) to: (a) any
affiliate of the Assigning Party, or (b) any entity which succeeds, by
purchasing stock or assets, by merger or otherwise, to all or substantially all
of the assets of the Assigning Party or right, title and interest of the
Assigning Party to Co-Developed Devices. Any attempted assignment, delegation,
encumbrance or other transfer in violation of this Agreement shall be void and
of no effect, and shall be a material breach hereof.


                      ARTICLE XVI - RESOLUTION OF DISPUTES

               16.1 Mediation. Except for any claims relating to the validity,
construction, scope, enforceability or infringement of any Patent rights, which
claims shall be resolved by a court of competent jurisdiction, and except for
the right of either party to apply to a court of competent jurisdiction for a
temporary restraining order or preliminary injunction to preserve the status quo
or prevent irreparable harm pending the selection and confirmation of a panel of
arbitrators, any dispute arising under this Agreement shall be resolved through
a mediation-arbitration approach. The parties agree to first try to resolve the
dispute informally with the help of a mutually agreed-upon mediator.


                                      -16-
<PAGE>   20
If it proves impossible to arrive at a mutually satisfactory solution through
mediation, the parties agree, upon the written demand of either party, to submit
their dispute to binding arbitration in accordance with the Commercial
Arbitration Rules of the American Arbitration Association.

               16.2 Arbitration. The arbitration may be conducted by one
impartial arbitrator by mutual agreement or by three arbitrators if the parties
are unable to agree on a single arbitrator within 30 days of first demand for
arbitration. All arbitrators are to be selected from a panel of candidates
having a background or training in photodynamic therapy, photoreactive drugs or
related light devices. The arbitrator or arbitrators shall determine the place
or places of arbitration having due regard for the convenience of the parties
and witnesses and the location of records. Upon request of a party, the
arbitrators shall have the authority to permit discovery to the extent they deem
appropriate. A court reporter shall record the arbitration hearing and the
reporter's transcript shall be the official transcript of the proceeding. The
arbitrators shall have no power to add or detract from the agreements of the
parties and may not make any ruling or award that does not conform to the terms
and conditions of this Agreement. The arbitrators shall have the authority to
grant injunctive relief in a form substantially similar to that which would
otherwise be granted by a court of law. The arbitrators shall have no authority
to award punitive damages or any other damages not measured by the prevailing
party's actual damages. The arbitrators shall specify the basis for any damage
award and the types of damages awarded. The decision of the arbitrators shall be
final and binding on the parties and may be entered and enforced in any court of
competent jurisdiction by either party. The prevailing party in the arbitration
proceedings shall be awarded reasonable attorney fees, expert witness costs and
expenses, and all other costs and expenses incurred directly or indirectly in
connection with the proceedings, unless the arbitrators shall for good cause
determine otherwise.

               IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed as of the day and year first written above.
