         2. GRANT

or sublicense outside the Territory, in each case with the right to sublicense,
under the Patent Rights and unpatented Know-How referred to in the following
sentence, to develop, manufacture, have manufactured, use and sell the Agreement
Product for eye care.

             (b) Under the foregoing license and sublicense, CVO shall have the
co-



                                        2.
   3
exclusive right to manufacture, have manufactured and use the Agreement Product
anywhere in the world, but CVO's right to sell the Agreement Product shall be
limited to the Territory, and CVO shall not seek directly or indirectly to sell
the Agreement Product outside the Territory. (It is understood, however, that
CVO's contract manufacturer(s) for the Agreement Product may sell the same to
CVO anywhere in the world for sale by CVO in the Territory only.)

                  (c) Under the foregoing co-exclusive license and sublicense,
CVO (and CVO's sublicensees) shall share with InSite the exclusive right under
the Patent Rights and Know-How referred to above to manufacture, have
manufactured, use and sell the Agreement Product in the Territory. Such sale of
the Agreement Product in the Territory by InSite may be made using InSite's own
sales force or by InSite's engaging in marketing activities with other companies
or entities that do not (and whose Affiliates do not) at the time of the
initiation of such engagement participate in the prescription and/or
over-the-counter ophthalmic pharmaceutical markets in the Territory, it being
understood, however, that the foregoing does not prohibit InSite's own sales
force or such other companies or entities from marketing the Agreement Product
to normal distribution channels such as wholesalers, drugstore chains,
independent manufacturers or independent sales representatives or agents,
retailers and health care providers (e.g., health maintenance organizations,
physicians, and preferred provider organizations) that sell prescription and/or
over-the-counter ophthalmic pharmaceuticals. InSite shall use good business
judgment, taking into consideration the overall sales of the Agreement Product,
in selecting any such independent manufacturers or independent sales
representatives or agents.

         Under the foregoing license and sublicense, CVO's right to manufacture,
have manufactured and use the Agreement Product outside the Territory shall be
non-exclusive. Under this Agreement InSite reserves the right to manufacture,
have manufactured, use and sell the Agreement Product outside of the Territory,
and to sublicense such rights outside of the Territory.

         2.2 The right of InSite to manufacture, have manufactured, use and sell
Agreement Product in the Territory which are reserved in the foregoing paragraph
shall not in any way be assigned or transferred to any third party; provided,
however, that such right may be assigned or transferred in a merger,
reorganization, sale of all or substantially all of InSite's assets, or
transaction whereby control of InSite changes, to InSite's successor in interest
in such transaction; provided, further, that upon the occurrence of any such
transaction InSite (or its successor in interest) shall not have the right to
sell any Agreement Product in any country in the respective Territory for such
Agreement Product except after the end of the fourth year following the date of
CVO's or CVO's Affiliates' first commercial sale in such country of such
Agreement Product (provided that such first commercial sale shall be deemed to
have occurred not later than one (1) year following the registration for sale of
such Agreement Product by the FDA or corresponding foreign agency for such
country with respect to either CVO or InSite), at which time InSite's right for
such Agreement Product may be assigned, transferred or sublicensed without
restriction hereunder.

         2.3 With respect to any Agreement Product and any country in the
Territory, until the end of the fourth year following the date of CVO's or CVO's
Affiliates' first commercial sale of such Agreement Product in such country
(provided that such first commercial sale shall be deemed to 


                                       3.
   4
have occurred not later than one (1) year following the registration for sale of
such Agreement Product by the FDA or corresponding foreign agency for such
country with respect to either CVO or InSite), CVO's right to grant any
sublicense under the Patent Rights and Know-How licensed or sublicensed by
InSite to CVO under this Article 2 shall be limited to sublicensing CVO's
Affiliates; and after such four (4) year period, CVO shall have the right to
grant such a sublicense to any third party to manufacture, have manufactured,
use and sell such Agreement Product in such country, provided, however, that if
CVO grants any such sublicense to any third party (other than CVO's Affiliates)
to sell such Agreement Product in such country, then the royalties payable by
such sublicensee to CVO shall not be less than * * * of such sublicensee's Net
Sales for such Agreement Product in such country, and with respect to such
Agreement Product CVO shall pay to InSite one-half of the excess of royalties
received by CVO from such sublicensee for such sublicensee's Net Sales in such
country, over the royalties payable by CVO to InSite resulting from such
sublicensee's Net Sales in such country under Article 5 below. CVO shall provide
InSite with a copy of the contractual provisions for any such sublicense to any
third party (other than CVO's Affiliates) which deal with royalty rates and
compensation, which copy shall be maintained in confidence by InSite pursuant to
Article 7 hereof. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL
TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED
SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.]

         2.4 Unless this Agreement is terminated for cause by InSite under
Sections 15.2 or 15.3, at the end of the Agreement Period for any Agreement
Product in any country in the Territory, CVO shall have the unrestricted
perpetual right to use the Patent Rights and Know-How that are licensed or
sublicensed by InSite above, free of charge, to manufacture, have manufactured,
and use such Agreement Product anywhere in the world and to sell such Agreement
Product in such country.

         2.5 CVO shall use commercially reasonable efforts consistent with good
business judgment to commercialize and sell the Agreement Product in the
Territory.

         2.6 CVO shall hereby be granted the limited right and license during
the Agreement Period and thereafter, unless CVO's rights are terminated pursuant
to Sections 15.2 or 15.3, to use InSite's DuraSite trademark solely in
connection with the marketing and sale of the Agreement Product.

         3. ROYALTIES

         3.1 In consideration of the rights granted in Section 2, during the
Royalty Period, CVO shall pay InSite royalties * * * of Net Sales of the
Agreement Product in the Territory so long as there is an enforceable, issued,
valid and unexpired patent identified in Patent Rights in the Territory covering
the Agreement Product. In the event there are no enforceable and valid patents
identified in the Patent Rights in the Territory, on a country-by-country basis,
the royalty rate hereunder shall be * * * of Net Sales. [* INDICATES THAT
MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED
THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE
COMMISSION PURSUANT TO RULE 24b-2.]


                                       4.
   5
         3.2 Sales of the Agreement Product between or among CVO, its Affiliates
and sublicensees shall not be subject to any royalty hereunder, and in such
cases royalties shall be calculated upon CVO or its Affiliates' or sublicensees'
Net Sales to an independent third party. CVO shall be responsible for payment of
any royalty accrued on Net Sales of the Agreement Product to such independent
third party through CVO's Affiliates or sublicensees. Royalties shall accrue
hereunder only once in respect of the same unit of the Agreement Product.

         4. TIMING OF ROYALTY PAYMENTS; RECORDS

         4.1 Within 45 days after the end of each calendar quarter during the
Royalty Period, CVO shall pay to InSite the royalty payment due for that quarter
in U.S. dollars.

         4.2 Together with each quarterly royalty payment, CVO shall submit to
InSite a written accounting showing its computation of royalties due under this
Agreement for such quarter. Said accounting shall set forth gross sales, Net
Sales, and the total royalties due for the quarter in question.

         4.3 CVO shall keep full and accurate books and records reflecting the
sales of Agreement Product and the data used in arriving at Net Sales and the
amount of royalties payable to InSite hereunder for no less than one year after
the end of each such quarter. CVO shall permit InSite, at InSite's expense, to
have such books and records examined by independent certified public accountants
retained by InSite and acceptable to CVO, during regular business hours upon
reasonable advance notice, but not later than one year following the rendering
of any such reports, accounting and payments, and no more often than one time
per year. Such independent accountants shall keep confidential any information
obtained during such examination and shall report to InSite only the amounts of
royalties which the independent accountant believes to be due and payable
hereunder.

         5. WARRANTIES

         5.1 InSite warrants and represents that:

             (a) it is the owner of the Patent Rights and Know-How and has the
right to license, in the manner set forth in this Agreement, said Patent Rights
and Know-How free of any lien or encumbrance in the Territory;

             (b) it has not assigned or conveyed any interest in the Patent
Rights or Know-How which may be inconsistent with the rights granted hereunder;

             (c) to the best of its knowledge and after a diligent search, the
practice of the Patent Rights and Know-How in the Territory does not infringe
any rights of third parties;

             (d) it is not aware that any third party is infringing the Patent
Rights;

             (e) it is a corporation duly incorporated and in good standing in
its state of 

                                       5.
   6
incorporation and has all requisite power to enter into and perform this
Agreement. Upon execution by the parties hereto, this Agreement shall constitute
a valid and legally binding obligation of InSite, enforceable in accordance with
its terms; and

             (f) it has prosecuted all patent applications within the Patent
Rights in good faith and has no reason to believe that any patent included
within the Patent Rights would be invalid or would be held to be unenforceable
by the court of competent jurisdiction.

         6. TRANSFER AND OWNERSHIP OF KNOW-HOW; TRANSFER OF ADVERSE DRUG
REACTION INFORMATION

         6.1 As part of the license granted in Section 2 hereof, and in order to
enable CVO to develop, make, have made, use and sell the Agreement Product,
InSite shall provide CVO with access to all Know-How within thirty days after
signing this Agreement. All Know-How generated or obtained by InSite during the
Agreement Period shall be made available to CVO within thirty days of its
generation or receipt by InSite. All such Know-How shall be provided to CVO as
confidential information subject to the confidentiality restrictions set forth
in this Agreement.

         6.2 InSite shall also assign to CVO the IND for the Agreement Product
and the data contained therein, and all pre-clinical data and regulatory
submissions for the Agreement Product, provided that InSite shall retain the
right to reference and use any of the foregoing for its own purposes consistent
with the terms of this Agreement. CVO shall own all subsequent regulatory
submissions for the Agreement Product, including the NDA therefor, and the data
contained therein. InSite understands and agrees that it shall not have any
ownership, or license rights in, or to, such submissions or other regulatory
filings of CVO for the Agreement Product, except that InSite shall be authorized
to reference such submissions in the event it wishes to manufacture or market
the Agreement Product pursuant to Section 2.4 hereof. CVO shall also have access
and a right of reference to any regulatory submissions made by InSite with
respect to the Agreement Product.

         6.3 All research and other information developed by CVO and its
Affiliates shall remain the property of CVO or its Affiliates, but InSite shall
have the right to access and reference such research and other information if it
decides to manufacture the Agreement Product pursuant to Section 2.4 hereof.

         6.4 During the Agreement Period, InSite shall report to CVO as soon as
practicable, and no later than five days following InSite's own notification,
any findings associated with the use of Agreement Product that may suggest
significant hazards, significant contraindications, significant side effects or
significant precautions pertinent to the safety of Agreement Product. In
addition, InSite shall provide CVO with notice of all adverse reaction
information in sufficient time to enable CVO to meet all requirements for
reporting such adverse reactions in the Territory.

         7. CONFIDENTIALITY

         7.1 InSite and CVO shall keep any Know-How or business information
provided 

                                       6.
   7
or made available by the other party or its Affiliates hereunder confidential,
and neither InSite nor CVO shall, without the prior written consent of the other
party or its Affiliates, as the case may be, use (except as expressly permitted
by this Agreement or for the purposes of this Agreement), or disclose to any
third party, any Know-How or business information provided or made available by
the other party or its Affiliates hereunder, provided, however, that the
foregoing shall not apply to information which the party receiving such
information can establish by written documentation to (i) have been publicly
known at the time of disclosure by the other party or its Affiliates, as the
case may be, (ii) have become publicly known, without fault on its part,
subsequent to such disclosure, (iii) have been otherwise known by it from a
source (other than the other party or its agents or Affiliates), lawfully having
possession of such information, or (v) have been developed by it or its
Affiliates independently of the disclosure by the other party or its Affiliates.

         The foregoing shall not preclude the disclosure of information by
InSite or CVO

             (a) to its legal representatives, Affiliates, consultants, outside
contractors and (if it has the right to grant the license or sublicense) its
licensees and sublicensees, under like confidentiality obligations on the part
of the recipients, or

             (b) to the extent required by law or regulation, provided that, to
the extent reasonably possible, it shall give prompt written notice of the
proposed disclosure to the other party or its Affiliates, as the case may be, so
as to allow the other party or its Affiliates, as the case may be, an
opportunity to object to such requirement and, if applicable, assure that
confidential treatment will be accorded to such information, or

             (c) to the extent that such information is reasonably required to
be disclosed for the purpose of securing necessary governmental authorization
for the clinical testing or marketing of products or for the purpose of
conducting clinical testing or marketing of products, or of prosecuting or
defending litigation.

         7.2 The terms of this Agreement shall not be disclosed by either party
to any third party (other than as provided in Sub-sections 7.1(a), (b) and (c)
above) or be published unless both parties expressly agree otherwise in writing.
Furthermore, neither party shall use the name of the other party or its
Affiliates without their prior written consent. However, all of the foregoing
restrictions shall not apply to the disclosure of information set forth in the
form of an agreed press release, if any, which may be prepared in mutually
agreeable format and substance for release when this Agreement becomes
effective, or to disclosures required by law or regulation.

         8. PATENTS

         8.1 InSite shall undertake and shall bear all costs of the prosecution
and maintenance of the Patent Rights in the Territory. InSite shall employ
reasonable efforts to keep CVO fully and timely informed in respect to the
course and conduct of patent application prosecution matters within the scope of
Patent Rights.



                                       7.
   8
         8.2 If InSite elects to terminate either the prosecution or maintenance
of the Patent Rights prior to the completion of normal prosecution before the
patent examiner or prior to the end of the term for maintenance, as the case may
be, it will give CVO 60 days prior written notice of such election prior to any
time limit on any action due. CVO, upon receipt of such notice, shall have the
option to undertake the continuation of such prosecution or maintenance and
InSite will transfer title to CVO for such patent application or patent.

         9. INFRINGEMENT OF PATENT RIGHTS

         9.1 If either party shall become aware of any infringement or
threatened infringement of any Patent Rights, including that contained in a
notice provided under the 1984 Act by a party filing an ANDA or Paper NDA for
Agreement Product, then the party having such knowledge shall give notice to the
other within 10 days of becoming aware of such infringement or threatened
infringement.

         9.2 CVO shall have the right to take such action, as it deems
appropriate, whether by action, suit, proceeding or otherwise, at its own
expense to prevent or eliminate, the infringement of Patent Rights by others and
to collect damages. InSite agrees to cooperate with CVO in any reasonable manner
including, but not limited to, being named as a co-plaintiff in an action
brought by CVO. CVO agrees to pay all reasonable out-of-pocket expense incurred
by InSite, in the prosecution of any such action, suit or proceeding for
infringement. Any damages recovered by the party bringing the action for patent
infringement shall be used to compensate that party for its out-of-pocket
expenses in the prosecution of any such action, suit or proceeding for
infringement. Any remaining damages recovered by that party shall be apportioned
between InSite and CVO in proportion to the damage incurred by each party as a
result of the infringement. To the extent that CVO cannot compensate its
out-of-pocket expenses in prosecuting said action by the recovered damages, CVO
may set off up to fifty percent (50%) of its reasonable out-of-pocket expenses
against royalties otherwise owed to InSite under this Agreement until CVO
reaches such 50% recovery point.

         9.3 In the event that CVO does not take action for patent infringement
pursuant to Section 9.2 to prevent or eliminate the infringement of Patent
Rights within 90 days of receipt of notice of the infringement or threatened
infringement thereof (or within 30 days in the event such infringement is by
Notice Under the 1984 Act), then within said 90 days (or within said 30 days if
such infringement is under the 1984 Act), InSite may, at its option, give notice
to CVO that unless CVO undertakes such action, InSite shall commence an action
to terminate such infringement. If CVO fails to take such action within said 90
days (or said 30 days in the event such infringement is by Notice Under the 1984
Act) then InSite shall have the right to take such action as it deems
appropriate against any infringer of same. Such action by InSite may be
undertaken in the name of CVO, if necessary, and CVO agrees to cooperate with
InSite, and execute any necessary documents relating to such action. In the
event the parties fail to bring such action to prevent or eliminate the
infringement of Patent Rights within 90 days of receipt of notice, CVO shall be
relieved of any obligation to pay patent royalties under Section 3 hereof until
such time as InSite shall obtain discontinuance of such infringement.

         At any time after commencement of any such infringement action by
InSite, CVO shall 


                                       8.
   9
have the right to become a party plaintiff in such action, and CVO shall have
the right to assume the prosecution, conduct and control of such action at CVO's
expense. Any recoveries in an action commenced by InSite shall be apportioned as
specified by Section 9.2.

         9.4 * * * [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL
TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED
SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.]

         10. THIRD PARTY RIGHTS

         10.1 If either party shall become aware of any action, or suit, or
threat of action or suit, by a third party alleging that the manufacture, use or
sale of the Agreement Product or the practice of Know-How infringes a patent, or
violates any other proprietary rights of any third party, the party aware shall
promptly notify the other party of the same and fully disclose the basis
therefor.

         10.2 CVO shall have the right at its own expense to compromise or
defend any such action or suit, or threat of action or suit, on such basis and
on such terms as CVO may determine as appropriate in its sole discretion, in its
own name, or jointly in the name of CVO and InSite or in the name of InSite, as
may be deemed necessary or appropriate by CVO. CVO shall keep InSite reasonably
informed as to the status of, and basis for, any such claim and shall consult
with InSite from time to time as to the defense of such suit or action. InSite
shall cooperate fully with CVO in the defense of such suit or action, including,
without limitation, by making all relevant papers and records available to CVO
and by making InSite's employees available for interviews and depositions and
CVO agrees to pay all reasonable out-of-pocket expenses incurred by InSite at
the request of CVO.

         10.3 If, by the terms of any settlement or if by a judgment, decree or
decision of a court, tribunal or other authority of competent jurisdiction, CVO
is required to obtain a license from a third party in order to make, have made,
use, sell or import Agreement Product (hereinafter "Third Party License") and to
compensate or pay damages to such third party and/or pay royalties under such
license, then any royalties payable under Section 3 of this Agreement shall be
reduced by (a) any damages paid or payable by CVO to such other party and (b)
the amount of royalties payable to InSite on future sales under such Third Party
License, provided such reduction shall not be greater than one-half (1/2) of the
royalties previously and hereafter payable to InSite pursuant to this Agreement.

         10.4 Nothing in this Section 10, or in Section 9, shall be construed as
a waiver or cure of any breach of any warranties set forth in Section 5 or any
release of any claim by CVO as may be appropriate relating thereto.

         11. PRODUCT LIABILITY

         11.1 CVO shall defend and hold InSite harmless from any product
liability claims and from any product liability damages arising from the
manufacture, use, sale or importation by CVO of the Agreement Product in the
Territory, provided that InSite notifies CVO of any such claims within 10 days
of receipt thereof and cooperates with CVO in defending against such claims. CVO
shall have complete control over the defense and/or disposition of any such
claim.


                                       9.
   10
         11.2 InSite shall defend and hold CVO harmless from any product
liability claims and from any product liability damages arising from the
manufacture, use, sale or importation by InSite of the Agreement Product in the
Territory, provided that CVO notifies InSite of any such claims within 10 days
of receipt thereof and cooperates with InSite in defending against such claims.
InSite shall have complete control over the defense and/or disposition of any
such claim.

         12. PATENT TERM EXTENSION

         12.1 Within 60 days after approval of an NDA for the Agreement Product,
and at CVO's option, CVO shall have the right to file at its own cost and
expense an application for an extension of any United States patent falling
within the Patent Rights, and, where applicable, for extension of Patent Rights
in any other country of the Territory under similar laws permitting patent term
extension. InSite designates CVO as its agent with respect to such filing and
prosecution for patent term extension, and agrees to cooperate with CVO in
providing any information required under the relevant United States laws or
similar laws outside the United States. Such action by CVO may be undertaken in
the name of InSite, if deemed necessary or appropriate by CVO, and InSite agrees
to cooperate with CVO, and execute any reasonably necessary documents relating
