     10-01 of Regulation  S-X. The  information  at June 30, 1996,  and for the
     three  month and six  month  periods  ended  June 30,  1996 and  1995,  is
     unaudited.  In the opinion of  management,  the  information  reflects all
     adjustments  necessary to make the results of  operations  for the interim
     periods a fair statement of such operations. All such adjustments are of a
     normal recurring nature. Interim results are not necessarily indicative of
     results for a full year.  For a  presentation  including  all  disclosures
     required by generally  accepted  accounting  principles,  these  financial
     statements  should be read in  conjunction  with the audited  consolidated
     financial  statements for the year ended December 31, 1995 included in the
     PDT,  Inc.  Annual  Report  on Form 10-K  filed  with the  Securities  and
     Exchange Commission.

2.   PER SHARE DATA

     Net loss per share is computed using the weighted average number of shares
     outstanding,  during the periods, as adjusted pursuant to the rules of the
     Securities  and  Exchange   Commission  for  certain   matters  for  which
     adjustments  would not be required to be  presented  under APB Opinion 15,
     for the  periods  prior to the  Company's  public  offerings.  All  stock,
     warrant, and option data included in the consolidated financial statements
     and footnotes reflect the effect of the three-for-two  stock split for all
     periods presented.

3.   PUBLIC OFFERING

     On April 30, 1996, the Company  completed a secondary  public  offering in
     which it sold  1,500,000  shares of Common  Stock with net proceeds to the
     Company of approximately $65.4 million.

4.   MARKETABLE SECURITIES

     Marketable securities are classified as available-for-sale  and are carried
     at market value.  Unrealized gains and losses are reported in shareholders'
     equity. Realized gains and losses on investment transactions are recognized
     when realized  based on settlement  dates and recorded as interest  income.
     Interest and dividends on securities are recognized when earned.  There was
     no unrealized gain or loss recorded as of June 30, 1996.

5.   COMMITMENTS

     In June 1996, the Company leased an additional facility with monthly rental
     of $47,000  which will  commence in September  1996.  The lease  expires in
     August  1999 and can be  extended  for three  years  thereafter.  The lease
     provides for annual rental increases based on the Consumer Price Index.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS
 
         The  following  discussion  should  be read  in  conjunction  with  the
consolidated  financial  statements and notes thereto.  This Quarterly Report on
Form 10-Q may be deemed to include forward looking statements within the meaning
of Section 27A of the  Securities  Act of 1933 and Section 21E of the Securities
Exchange  Act of 1934 that involve risk and  uncertainty,  including  financial,
clinical,  business  environment  and trend  projections.  Although  the Company
believes that its expectations are based on reasonable assumptions,  it can give
no assurance that its goals will be achieved.  The important  factors that could
cause  actual  results to differ  materially  from those in the forward  looking
statements herein include, without limitation, the early stage of development of
both the Company and its products, the timing and uncertainty of results of both
research  and  regulatory   processes,   the  extensive  government   regulation
applicable to the Company's  business,  the unproven  safety and efficacy of the
Company's  drug  and  device  products,  the  Company's  significant  additional
financing  requirements,  the uncertainty of future capital funding,  the highly
competitive environment of the international  pharmaceuticals and medical device
industries  and the  presence  of a number  of  competitors  with  significantly
greater  financial,  technical  and  other  resources  and  extensive  operating
histories,  the  Company's  potential  exposure to product  liability or recall,
uncertainties  relating to patents and other  intellectual  property,  including
whether the Company will obtain sufficient  protection or competitive  advantage
therefrom and the Company's  dependence  upon a limited  number of key personnel
and consultants and its significant reliance upon its collaborative partners for
achieving its goals.


GENERAL

         Since its  inception,  PDT, Inc. ("the  Company") has been  principally
engaged in the research and development of drugs and medical device products for
use in  photodynamic  therapy.  The  Company  has been  unprofitable  since  its
founding and has incurred a cumulative net loss of  approximately  $43.0 million
as of June 30, 1996. The Company  expects to continue to incur  substantial  and
increasing  operating  losses for the next several  years due to  continued  and
increased  spending  on  research  and  development  programs,  the  funding  of
preclinical  and clinical  testing and  regulatory  activities  and the costs of
manufacturing and administrative activities.

         The  Company's  revenues  primarily  reflect  income earned from device
product  sales,  grants,  contracts  and  licensing  agreements.  Product  sales
represent limited sales of photodynamic  therapy devices (e.g.,  light producing
devices and light delivery and measurement devices),  sold both domestically and
internationally, to researchers and an OEM distributor. To date, the Company has
received  no  revenue  from the sale of drug  products,  and the  Company is not
permitted to engage in commercial  sales of drugs or devices until such time, if
ever, as the Company receives requisite regulatory  approvals.  As a result, the
Company does not expect to record significant product sales until such approvals
are received.

         Until the Company  commercializes  its product(s),  the Company expects
revenues to continue to be attributed to grants, contracts, licensing agreements
and device product sales for research use. The Company  anticipates  that future
revenues and results of  operations  will  continue to  fluctuate  significantly
depending on, among other factors,  the timing and outcome of  applications  for
regulatory approvals, the Company's ability to successfully manufacture,  market
and distribute its drug products and device products and/or the establishment of
collaborative arrangements for the manufacturing,  marketing and distribution of
some of its products.

         The  Company has  completed  Phase I/II  clinical  trials in the United
States  using  its drug  candidate  SnET2  for the local  treatment  of  certain
nonmelanoma skin cancers and AIDS-related  Kaposi's Sarcoma ("KS").  The Company
has  initiated  Phase III clinical  trials for KS and  metastatic  breast cancer
involving the skin and, based on clinical results and after review with the FDA,
plans to begin  enrolling  patients in Phase III clinical  trials for basal cell
carcinoma in 1996.  In May,  the Company  began Phase I/II  clinical  studies in
ophthalmology,  using  SnET2  to treat  complications  of  advanced  age-related
macular degeneration (AMD), a leading cause of blindness. The Company is also in
various stages of preclinical testing of SnET2 and other photoreactive drugs for
the treatment of other cancers,  certain  cardiovascular  conditions,  urologic,
gynecologic and dermatologic conditions and eye disorders.

         The Company has awarded stock options that vest upon the achievement of
certain  milestones.  Under  Accounting  Principles  Board  Opinion No. 25, such
options  are  accounted  for as  variable  stock  options.  As such,  until  the
milestone is achieved (but only after it is determined to be probable), deferred
compensation  is recorded in an amount equal to the difference  between the fair
market  value of the Common Stock on the date of  determination  less the option
exercise  price and is adjusted from period to period to reflect  changes in the
market  value of the Common  Stock.  Deferred  compensation,  as it relates to a
particular  milestone,  is amortized over the period between when achievement of
the  milestone  becomes  probable  and when the  milestone  is  estimated  to be
achieved.  Amortization  of deferred  compensation  could result in  significant
additional  compensation  expense being  recorded in future periods based on the
market value of the Common Stock from period to period.

         Effective  June 21, 1996,  the  Compensation  Committee of the Board of
Directors  adjusted the future  vesting  periods of the variable  stock  options
covering  400,000  shares of Common  Stock.  These  variable  stock options were
adjusted  to change  the  vesting  periods to  specific  dates as opposed to the
original vesting periods which were based upon the achievement of milestones; no
change was made to the exercise  prices of these variable  stock  options.  This
change in the vesting  periods  provides for the options to be accounted  for as
non-variable   options  and   therefore   alleviates   the  impact  of  deferred
compensation  expense  fluctuating in future periods based on the changes in the
per share  market value period to period.  At June 30,  1996,  options  covering
160,000 shares with an exercise price of $34.75 per share have vested and 67,500
shares are expected to vest during the remainder of 1996. The remaining unvested
shares will vest in the years 1997  through  2000.  Based on the decrease in the
per share  market  value of the Common Stock from $59.00 as of March 31, 1996 to
$35.50 per share as of June 21,  1996 (the  effective  date of the change in the
vesting  periods),  the  Company  recorded a deferred  compensation  adjustment,
associated  with these  variable  stock  options,  of $3.2 million for the three
months ended June 30, 1996.


RESULTS OF OPERATIONS

        The following table provides a summary of the Company's revenues
           for the three and six months ended June 30, 1996 and 1995.

                      Three months ended June 30,    Six months ended June 30,
Consolidated Revenues     1996           1995            1996           1995
                      ------------  ------------    ------------  ------------ 
Product sales         $      3,000  $      4,000    $      4,000  $     12,000

License                    749,000            --       1,121,000            --
                      ------------  ------------    ------------  ------------
Total revenue         $    756,000  $     47,000    $  1,385,000  $    192,000
                      ============= ============    ============  ============

         REVENUES.  For the three months ended June 30, 1996, revenues increased
to $756,000 from $47,000 in the three months ended June 30, 1995. Total revenues
for the six months ended June 30, 1996  increased to $1.4 million from  $192,000
in the first six months of 1995.  The  increase  for the three months ended June
30, 1996  relates to the  increase in license  income which was $749,000 in 1996
compared  to  no  license  income  for  the  same  period  of  the  prior  year.
Additionally,  license  income for the six months  ended June 30,  1996 was $1.1
million compared to no license income for the same period in 1995. The increases
in license  income are due to the  commencement  in 1996 of the  billing for the
reimbursement  of  clinical  costs  related  to the  Pharmacia  &  Upjohn,  Inc.
("Pharmacia & Upjohn") license agreement.  Grant income for the six months ended
June 30, 1996 increased to $256,000 from $141,000 for the  comparable  period of
the prior year.  The Company  expects grant income to be a continuing  source of
revenue during the remainder of 1996.

         COST OF GOODS SOLD.  Cost of goods sold for the three months ended June
30, 1996  decreased  to $2,000 from  $11,000 for the three months ended June 30,
1995.  For the six months ended June 30, 1996,  cost of goods sold  decreased to
$4,000 from $33,000 in the first six months of 1995. The decrease was due to the
decrease  in product  sales  during  1996  based on the  Company's  decision  to
allocate its manufacturing  resources to supporting its preclinical and clinical
testing.

         RESEARCH  AND  DEVELOPMENT.  The  Company's  research  and  development
expenses  for the three months  ended June 30, 1996  increased to $3.38  million
from  $1.6  million  in the three  months  ended  June 30,  1995.  Research  and
development  expenses for the six months  ended June 30, 1996  increased to $8.0
million from $2.79 million for the six months ended June 30, 1995.  The increase
in expense for the three and six month  periods  ended June 30, 1996 compared to
the same periods in 1995 relate  primarily to the significant  increase in costs
associated with the development of drug formulation, an increase in the purchase
of raw  materials and supplies  used in the  production of clinical  devices and
drug product in connection with clinical trials and an increase in payroll costs
due to the growth of research and development personnel.  The increases in costs
for the three month period ended June 30, 1996 were offset by a decrease of $1.0
million in deferred  compensation expense associated with the decline in the per
share market value of the variable stock options, as well as the changing of the
vesting  periods of the variable stock  options,  as discussed  previously.  The
Company  anticipates that future research and development  expenses,  as well as
other  expenses,  will increase  significantly  during the remainder of 1996 and
beyond as the Company  expands its  research  and  development  programs,  which
include the hiring of personnel and the continued  expansion of preclinical  and
clinical testing.

         SELLING, GENERAL AND ADMINISTRATIVE. The Company's selling, general and
administrative  expenses for the three  months ended June 30, 1996  decreased by
$1.3 million from the comparable  period of the prior year. The decrease relates
primarily  to the decrease of $2.1 million in  compensation  expense  associated
with the decline in the per share market value of the variable stock options, as
well as the changing of the vesting  periods of the variable stock  options,  as
discussed  previously.  This  decrease  in  compensation  expense  was offset by
increased  costs  received from  professional  services  consisting of financial
consultants,  attorneys  and public  relations and the increase in payroll costs
due to the addition of  personnel.  Total  selling,  general and  administrative
expenses for the six months ended June 30, 1996  increased to $2.51 million from
$1.46  million for the six months ended June 30, 1995.  The increase  relates to
the increase in professional  services received and personnel costs. The Company
expects future selling,  general and administrative  expenses to increase in the
remainder of 1996 and beyond due to the increased  support required for research
and development  activities,  continuing corporate  development and professional
services, and general corporate activities.

         INTEREST  INCOME.  For the three months  ended June 30, 1996,  interest
income  increased  to $627,000  compared  to interest  income of $22,000 for the
three months ended June 30, 1995.  Interest income for the six months ended June
30,  1996  increased  to $710,000  from  $28,000 in the same period of the prior
year.  The increases in interest  income result from the  investment of proceeds
received from the Company's  secondary public offering in April 1996, as well as
the  continued  interest  income from the proceeds  from the  Company's  initial
public  offering and the Pharmacia & Upjohn  investment in the Company's  Common
Stock.

         INTEREST EXPENSE.  Interest expense for the three months ended June 30,
1996 decreased to $10,000  compared to interest expense of $28,000 for the three
months  ended June 30, 1995.  For the six months  ended June 30, 1996,  interest
expense  decreased to $18,000 from $99,000 in the comparable period of the prior
year.  The  decreases  result  primarily  from the  conversion  of the Company's
convertible notes to Common Stock  (approximately 79% were converted in December
1994, 18% were converted during 1995 and 2% have been converted during 1996).

         The Company does not believe that  inflation has had a material  impact
on its results of operations.

LIQUIDITY AND CAPITAL RESOURCES

         Since  inception  through June 30, 1996, the Company has  accumulated a
deficit  of  approximately  $43.0  million  and  expects  to  continue  to incur
substantial  and increasing  operating  losses for the next several  years.  The
Company  has  financed  its  operations  primarily  through a  secondary  public
offering in April  1996,  Pharmacia & Upjohn's  purchase  of Common  Stock,  its
initial public  offering and private  placements of common and preferred  stock,
and private  placements of convertible  notes and short term notes,.  As of June
30,  1996,  the  Company  had  received  net  proceeds  from the sale of  equity
securities and convertible notes of approximately  $110.7 million.  In addition,
the Company has financed a substantial portion of its leasehold improvements and
certain equipment  through capital lease  obligations,  a leasehold  improvement
loan and a bank line of credit.  The Company has  available a $1.0  million bank
line of credit which has a variable rate of interest based on the bank's lending
rate (7.8% as of June 30,  1996),  which  expires on January  31,  1997,  and is
collateralized by the Company's cash balances. The credit agreement subjects the
Company  to certain  customary  restrictions,  including  a  prohibition  on the
payment of dividends.  The Company presently has no outstanding borrowings under
the bank line of credit.

         In April 1996,  the Company  completed a secondary  public  offering of
1,500,000  shares of Common Stock which  provided net proceeds to the Company of
approximately  $65.4 million.  These proceeds are anticipated to be used to fund
preclinical and clinical  testing,  research and development and the balance for
general  corporate  activities.  Pending such uses, the Company has invested the
net proceeds in short-term, interest-bearing obligations and which may primarily
consist   of  those   issued  by  the  U.S.   Government,   its   agencies   and
instrumentalities.

         In connection with the licensing agreement with Pharmacia & Upjohn, the
Company has recorded as license income for the  reimbursement  of clinical costs
of $722,000 in the second  quarter of 1996,  and $1.1 million for the six months
ended June 30, 1996. The Company  anticipates  recording  license income for the
reimbursement of clinical costs throughout the remainder of 1996 and beyond.

         For the  first  six  months  of 1996,  the  Company  required  cash for
operations of approximately  $7.5 million compared to $3.06 million for the same
period in 1995.  The increase in cash used in operations was primarily due to an
increase in operating  activities  associated  with the  continued  expansion of
preclinical  and clinical  testing,  the  increase in research  and  development
activities, the growth of research and development and support personnel and the
increase in general corporate activities.  For the first six months of 1996, the
Company received net cash from its financing  activities of approximately  $66.0
million as compared to $4.6  million for the same period in 1995.  The  increase
results from the sale of Common Stock in the Company's secondary public offering
which closed in April 1996.

         The  Company  invested  a total of  $665,000  in  property,  plant  and
equipment during the first six months of 1996 as compared to $315,000 during the
same  period in 1995.  The  Company  expects  to  purchase  property,  plant and
equipment  during the remainder of 1996 as the Company expands its  preclinical,
clinical and  research and  development  activities.  In June 1996,  the Company
entered into an agreement for the leasing of an additional  facility  which will
commence in September 1996.  (See Note 5 of the Notes to Consolidated  Financial
Statements.) The move to this facility will require additional  expenditures for
the  construction  of  the  laboratories  and  office  space  and  purchases  of
equipment.   Since  inception,  the  Company  has  entered  into  capital  lease
agreements  for  approximately  $184,000 of equipment,  consisting  primarily of
laboratory  equipment.  The Company  expects to continue to lease equipment from
time to time as needed.

         The Company's  capital  requirements  will depend on numerous  factors,
including the progress and magnitude of the Company's  research and  development
programs and  preclinical and clinical  testing,  the time involved in obtaining
regulatory approvals, the cost involved in filing and maintaining patent claims,
technological  advances,  competitor and market  conditions,  the ability of the
Company  to  establish  and  maintain  collaborative  arrangements,  the cost of
manufacturing  scale-up  and the cost  and  effectiveness  of  commercialization
activities and arrangements.

         The Company  has raised  funds in the past  through  public and private
placement  offerings.  In April 1996, the Company  completed a secondary  public
offering  of  Common  Stock  which  provided  net  proceeds  to the  Company  of
approximately  $65.4  million.  The Company  believes  that these  funds  should
satisfy  its  capital  requirements  for the next few  years.  The  Company  may
contemplate  raising funds in the future through  public or private  financings,
collaborative arrangements or from other sources. The success of such efforts in
the  future  will  depend in large  part  upon  continuing  developments  in the
Company's  preclinical  and  clinical  testing and the  success of  photodynamic
therapy in  general.  The  Company is also in  discussion  with other  companies
regarding   the   potential   for  license   agreements,   equity   investments,
collaborative arrangements, or development or other funding programs in exchange
for  marketing,  distribution  or other  rights  to  products  developed  by the
Company.  However,  there  can  be no  assurance  that  discussions  with  other
companies will result in any investments, collaborative arrangements, agreements
or funding.

right,  title and  interest in and to IRIDEX  Technology.  PDTI shall retain the
entire right,  title and interest in and to all PDTI Drugs,  and nothing in this
Agreement shall give IRIDEX any rights in or to any PDTI Drugs.

         2.02     License to IRIDEX.
         Subject to the terms of this Agreement, PDTI hereby grants to IRIDEX an
exclusive,  worldwide  license under the  Co-Developed  Technology to make, have
made, use, offer for sale,  import,  export,  distribute,  and sell Co-Developed
Devices in the  Field.  IRIDEX may  sublicense,  totally or in part,  the rights
granted to it under this Section  2.02, or may appoint one or more third parties
to  subdistribute  Co-Developed  Devices in the Field;  provided,  however,  (i)
IRIDEX must notify PDTI, in writing,  of each such sublicense or  subdistributor
at least fifteen (15) days in advance;  (ii) IRIDEX remains  responsible to PDTI
for all contractual obligations of the sublicensee or subdistributor  including,
but not  limited  to,  keeping of  records,  reporting  of sales and  payment of
invoices, as if the sublicensee's or subdistributor's  sales were IRIDEX's sales
and (iii) the sublicensee or  subdistributor  agrees to be bound by the terms of
this Agreement to the same extent as IRIDEX.

begin making a particular Co-Developed Device or after receipt of all applicable
regulatory approvals for such Co-Developed Device to begin using or distributing
a particular  Co-Developed  Device in the Field,  or decides to  discontinue  so
making,  using and  distributing  such  Co-Developed  Device,  then the  license
granted  to  IRIDEX  in  Section  2.02  hereof  shall  no  longer  apply to such
Co-Developed Device and IRIDEX shall thereupon be deemed to have granted to PDTI
an exclusive,  worldwide,  paid-up license under the Co-Developed Technology and
such IRIDEX Technology,  as may be required, to make, use, distribute,  and sell
such Co-Developed Device in the Field. PDTI may thereafter  sublicense,  totally
or in part, the rights granted to it under this Section 2.03, or may appoint one
or more third parties to subdistribute  such  Co-Developed  Device in the Field;
provided,  however,  (i) PDTI  must  notify  IRIDEX,  in  writing,  of each such
sublicense  or  subdistributor  at least thirty (30) days in advance;  (ii) PDTI
remains responsible to IRIDEX for all contractual obligations of the sublicensee
or subdistributor  including, but not limited to, keeping of records,  reporting
of sales and payment of invoices,  as if the  sublicensee's or  subdistributor's
sales were PDTI's sales and (iii) the sublicensee or subdistributor agrees to be
bound by the  terms of this  Agreement  to the same  extent  as PDTI.  If IRIDEX
decides to  discontinue so making,  using or does not use reasonable  commercial
efforts to continue  distributing such  Co-Developed  Device, it shall give PDTI
written notice of such decision and agrees to continue making such  Co-Developed
Device for PDTI for a period of nine (9) months  after the date of  delivery  of
such  written  notice  or until  PDTI  determines  that it is able to make  such
Co-Developed  Device,  whichever is sooner,  whereupon  IRIDEX shall transfer to
PDTI, as no cost to PDTI, such information under the IRIDEX Technology as may be
required for PDTI to make such Co-Developed Device.

         2.04     Exclusivity.
         During the term of this  Agreement,  except as permitted under Sections
2.02, 2.03 and 2.05 hereof or as otherwise  agreed to in writing by the parties:
(i) neither PDTI nor IRIDEX shall, directly or indirectly,  grant any rights in,
to or under the  Co-Developed  Technology to any third party;  (ii) neither PDTI
nor IRIDEX shall, directly or indirectly, make, use, sell, distribute or license
Co-Developed  Devices  outside the Field;  (iii) IRIDEX  shall not,  directly or
indirectly,  make, use, sell, distribute or license any Co-Developed Device with
any Photodynamic  Therapy drug other than PDTI Drugs; and (iv) IRIDEX shall not,
directly  or  indirectly,  make,  use,  sell,  distribute  or license any IRIDEX
Technology or any products  developed  thereunder,  in the Field,  other than as
required for the manufacture, use, sale, distribution or license of Co-Developed
Devices in the Field.  Notwithstanding  any  provision  in this  Agreement,  the
parties  acknowledge and agree that nothing contained in this Agreement shall be
deemed  to  restrict  or  prevent  IRIDEX  from  engaging  in  any  business  or
developing,  making, using, selling,  offering for sale, importing and exporting
any products that are used in conjunction with ICG in IRIDEX's sole and absolute
discretion.

         2.05     Conditions to Consents.
         In accordance with Section 2.04,  prior to agreeing in writing to allow
the other party (the  "Granting  Party") to grant any rights in, to or under the
Co-Developed  Technology  to any third  party with  respect  to any  instrument,
device or other product (hereinafter  referred to as a "Third Party Co-Developed
Device"), PDTI or IRIDEX, as the case may be, shall have the right to review and
approve the terms of the  arrangement  between the Granting Party and such third
party. The terms of such  arrangements  shall provide at a minimum that: (i) the
Granting  Party may sell Third  Party  Co-Developed  Devices to such third party
only for resale by such third party and the  Granting  Party shall not  directly
sell or provide  products or services to the end user, and (ii) a royalty on the
Net Sales of Third Party Co-Developed Devices shall be due to the other party at
a rate  pursuant to the royalty  provisions  set forth in Section  5.02.  In the
event that either PDTI or IRIDEX  agrees to allow the other party to make,  use,
sell,  distribute or license  Co-Developed  Devices outside the Field, the other
party shall pay to the first party a mutually agreed to royalty on the Net Sales
of such devices.

meet to discuss the commercial impact of such third party infringement.

         7.03     Initiation of Action by PDTI or IRIDEX.
         If PDTI and  IRIDEX  determine  to  jointly  institute  any  action  in
connection with the infringement described in Section 7.02, then PDTI and IRIDEX
shall share  equally in the costs of such action and in the full recovery of any
money or other property collected by way of judgment,  settlement (whether prior
to or after the  institution  of any action or  proceeding)  or otherwise on any
action initiated jointly by the parties. If either PDTI or IRIDEX determines not
to be involved in any such  action,  then it will execute an  assignment  of its
rights to the other party, and the other party may take all steps in the name of
both parties which are necessary or advisable including, without limitation, the
institution  of any action or  proceeding  for the  obtaining  of damages or the
enjoinment  of any such  infringement  and to prosecute,  settle,  compromise or
otherwise dispose of the same. That party, whether PDTI or IRIDEX, shall pay all
costs  incurred  pursuant to this Section 7.03 and shall be entitled to the full
recovery of any money or other property collected by way of judgment, settlement
(whether  prior to or after the  institution  of any  action or  proceeding)  or

Technology  hereunder,  PDTI or IRIDEX shall  promptly so notify the other.  The
parties  shall then  consult  with each other as to the course of action to take
relative to such third party claim and shall  cooperate  in  defending or taking
such  other  action  as  they  shall  reasonably  agree  with  respect  to  such
Co-Developed Devices or Co-Developed Technology. Each party hereto shall pay its
own  expenses in  defending  any such third party  claim.  Each shall  solely be
responsible for any infringement claims on that party's  trademarks,  Patents or
other intellectual property and for all related damages incurred.

         7.05     Damages to Third Party.
         If, in any such action  described in Section 7.04, a court of competent
jurisdiction  determines  that either PDTI or IRIDEX is obligated to pay damages
to any third person  (excluding  trademark  claims)  because  PDTI's or IRIDEX's
manufacture,  use, sale, distribution or licensing of Co-Developed Technology or
Co-Developed Devices was held to be an infringement of a third party right, then
the infringing party shall pay such damages; provided, however, that if PDTI and
IRIDEX are  determined to be jointly  responsible,  the parties shall share such
damages to the extent that each party is determined to be responsible.

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

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

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

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

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).

         Notice  of change  of  address  shall be  deemed  given  when  actually
received,  all other Communications shall be deemed to have been given, received
and dated on the earlier  of: (i) when  actually  received,  or on the date when

telex (each promptly  confirmed by a writing as aforesaid) or overnight courier;
or four (4) business days after mailing.

         14.05    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.

         14.06    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 any term or  provision  of this  Agreement on the part of such other
party to be performed or complied  with.  The waiver by either party hereto of a
breach of any term or  provision of this  Agreement  shall not be construed as a
waiver of any subsequent breach.

         14.07    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.

         14.08    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

         16.01    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.  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.

         16.02    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 cause  this  Agreement  to be
executed as of the day and year first written above.
