            3. Records and Audit Rights. Each party shall have the right to hire
an independent certified public accountant to inspect all the above required
records (who shall agree in writing to keep all information confidential except
as needed to disclose any discovered discrepancies); provided, such audit: (i)
is conducted during normal business hours, (ii) is conducted no more often than
twice per year (unless a discrepancy is discovered in favor of the auditing
party), and (iii) is conducted only after the audited party has been given
thirty (30) days prior notice. The auditing party shall bear the full cost and
expense of such audit, unless a discrepancy in excess of ten percent (10%) in
favor of the auditing party is discovered, in which event the audited party
shall bear the full cost and expense of such audit. Regardless of the amount of
discrepancy discovered, all discrepancies (and interest thereon) shall be
immediately due and payable.

         D. License and Marketing Obligations.

            1. Exclusive License. Subject to the terms and conditions of this
Agreement and during the term hereof, InSite hereby grants B&L an exclusive
product license or sublicense under the Patents and unpatented Know-How to
manufacture, have manufactured, use, import, sell and sublicense the Timolol
Product in the Territory.

            2. Right to Sublicense. B&L shall make all payments to InSite on
behalf of its Affiliates and sublicensees. In addition, B&L will cause such
Affiliates or sublicensees to satisfy and honor all the obligations, limitations
and restrictions of or on B&L under this Agreement.

            3. Royalties.

               a. In consideration of the rights granted above, during the
Royalty Period in any country, B&L shall pay InSite royalties consisting of * *
* of Net Sales of the Timolol Product in such country. In the event that during
the Royalty Period for any country, any of InSite's Patents expire or are
invalidated and generic versions of the Timolol Product are being sold in such
country (and such generic sales are not in contravention of any governmental,
judicial or private regulatory rules, regulations, laws, orders or judgments in
effect in such country), the royalty rate paid by B&L shall be reduced to * * *
of Net Sales in such country. During the Secondary Royalty Period in any
country, B&L shall pay InSite the following royalties on Net Sales of the
Timolol Product: (i) * * * of Net Sales of the Timolol Product during the first
year of the Secondary Royalty Period; (ii) * * * of Net Sales of the Timolol
Product for the second year of the Secondary Royalty Period; and (iii) * * * of
Net Sales of the Timolol Product during the third year of the Secondary Period
and during any subsequent year in which this Agreement or any extension thereof
is in effect. In addition, during the Secondary Royalty Period in any country,
B&L shall pay InSite royalties of * * * of Net Sales of the Generic (as defined
below) unless B&L's sale of the Generic was pursuant to the filing of an ANDA
(as hereinafter defined) and without any cooperation from InSite whatsoever, in
which event B&L's obligation to pay a royalty of * * * shall terminate after the
passage of * * * years after the commencement of the Secondary Royalty Period.
Notwithstanding anything contained 

                                      11.
   12
herein to the contrary, B&L shall not be required to pay InSite any royalty on
Net Sales of the Generic after the end of the * * * year of the Secondary
Royalty Period. [* 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.]

                  b. Notwithstanding anything in this Agreement to the contrary,
if any of the Patents expire or are invalidated, or if InSite is unable or
elects not to obtain a patent in such country, and generic versions of the
Timolol Product are being sold in such country (and such generic sales are not
in contravention of any governmental, judicial or private regulatory rules,
regulations, laws, orders or judgments in effect in such country), B&L shall
have the right to manufacture, use, sell and distribute a generic equivalent of
the Timolol Product by either submitting and receiving approval of an
abbreviated new drug application, and, with respect to countries other than the
United States, the equivalent abbreviated application ("ANDA") or obtaining from
InSite, if necessary, the right to supplement or amend any Regulatory Approval
to introduce a generic form of the Timolol Product (the "Generic"). If B&L
submits an ANDA for the Generic, it shall notify InSite in writing at least
ninety (90) days prior to the date of submission and InSite shall cooperate with
B&L in the preparation of such submission. Alternatively, if B&L elects to
submit a supplement to the NDA with respect to the Generic, B&L may request from
InSite, and InSite shall grant B&L, such specific rights to the Regulatory
Approval as are necessary to enable B&L to submit such supplement to introduce
and sell the Generic. If B&L elects to launch the Generic in any country prior
to the end of the Royalty Period in such country, in anticipation of the entry
of a third party generic competitor, the royalty due on sales of such Generic by
B&L shall be * * * of Net Sales until the end of the Royalty Period. InSite
hereby covenants not to sue B&L for patent infringement relating to sales of the
Generic which are in accordance with this Section D.3.1(b) during the Royalty
Period in such country. [* 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.]

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

         4. Timing of Royalty Payments; Records.

            a. Within 45 days after the end of each calendar quarter, B&L shall
pay InSite the royalty payment due for such quarter in U.S. dollars. All royalty
payments shall be made via wire transfer of same day funds to such account as
shall be designated by InSite not

                                      12.
   13
later than five (5) days prior to the date such payment is due. Such royalty
shall be converted, where applicable, from the currency of the country in which
the sale was made into U.S. dollars at the average month-end exchange rate for
such quarter as calculated based on the daily exchange rates published in The
Wall Street Journal. 

            b. Together with each quarterly royalty payment, B&L 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, the exchange rate applied, if any, and the total royalties due for the
quarter in question.

            c. B&L shall keep full and accurate books and records reflecting the
sales of the Timolol 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. B&L shall permit InSite, at InSite's expense, to
have such books and records examined by independent certified public accountants
retained by InSite and reasonably acceptable to B&L, 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.

         E. Ownership.

            1. Ownership. As between the parties, the parties shall have the
ownership rights set forth below:

               a. (i) Subject to the rights of B&L set forth in Section E.1.c.,
InSite shall have all right, title and interest (including all patent rights
throughout the world) in any inventions, ideas or information made or conceived
or reduced to practice by either InSite or B&L in the course of development of
the Timolol Product hereunder which relate to the DuraSite delivery system (an
"Improvement"); and (ii) subject to the rights of InSite set forth in Section 
E.1.d., B&L shall have all right, title and interest (including all patent
rights throughout the world) in any inventions, ideas or information made or
conceived or reduced to practice by either InSite or B&L in the course of
development of the Timolol Product hereunder which relate to Timolol. B&L shall
have the right to acquire a nonexclusive license to any such Improvement on
terms reasonably agreed to by the parties.

               b. Provided, as to any inventions, ideas or proprietary
information made or conceived or reduced to practice by either party prior to
the Effective Date of this Agreement that relates directly or indirectly to the
Timolol Product ("Precollaborative Inventions"), InSite (if such
Precollaborative Invention is made, conceived or reduced to practice by B&L) or
B&L (if such Precollaborative Invention is made, conceived or reduced to
practice by InSite) shall have a paid-up, non-exclusive license to exploit such
invention, idea or information as it relates to and solely for use with the
Timolol Product and the Collaborative 

                                      13.
   14
Project. Provided, however, that neither party, as the case may be, shall use
such idea, invention or proprietary information for the development or
manufacture of products for any entity other than the other party or an assignee
permitted under this Agreement. Such non- exclusive license shall terminate upon
termination of this Agreement. Provided, that either party, as the case may be,
shall be free to use for any purpose, without any accounting to the other party,
any information of the types described below in Section F(i)-(iv).

               c. Provided, as to any inventions, ideas or information conceived
or reduced to practice by InSite or the parties jointly in the course of
development of the Timolol Product in connection with this Agreement which
relates to Timolol and which may be exploited in a delivery system other than
DuraSite (which are provided for in Sections E.1.d. and E.1.e., below), B&L
shall have a perpetual, paid-up, exclusive right to exploit (by itself or with a
third party) such invention, idea or information as it relates to Timolol for
all purposes other than delivery through the DuraSite system.

               Provided further, consistent with patent law and sound patent
practice, B&L in good faith will seek to separate from other patent applications
any applications for any invention claiming Timolol exclusive of DuraSite.
Provided, however, B&L shall not be required to take any action which would in
any way detract from, jeopardize or limit any patent application resulting from
the development of the Timolol Product under this Agreement. Provided, further,
in the event that a patent is issued the claims of which include Timolol but do
not include the DuraSite delivery system in any respect, B&L may obtain the
rights to an assignment of such patent and InSite shall facilitate such
assignment; in such case, B&L shall reimburse InSite for all costs and expenses
associated with the preparation and prosecution of such patent application.

               d. Provided, as to any inventions, ideas or information conceived
or reduced to practice by B&L or the parties jointly in the course of
development of the Timolol Product in connection with this Agreement which
relates to the DuraSite delivery system, InSite shall have a perpetual, paid up
exclusive right to exploit (by itself or with a third party) such invention,
idea or information as it relates to the DuraSite delivery system.

               Provided further, consistent with patent law and sound patent
practice, InSite in good faith will seek to separate from other patent
applications any applications for any invention relating to the DuraSite
delivery system. Provided, however, InSite shall not be required to take any
action which would in any way detract from, jeopardize or limit any patent
application resulting from the development of the Timolol Product under this
Agreement. Provided, further, in the event that a patent is issued the claims of
which include the DuraSite delivery system, but do not include other delivery
systems in any respect, InSite may obtain the rights to an assignment of such
patent and B&L shall facilitate such assignment; in such case, InSite shall
reimburse B&L for all costs and expenses associated with the preparation and
prosecution of such patent application.


                                      14.
   15
                    e. Provided, as to any Joint Invention relating in whole or
in part to the DuraSite delivery system (with or without Timolol), InSite shall
have a perpetual, paid up exclusive right to exploit (by itself or with a third
party) such Joint Invention, idea or information as it relates to the DuraSite
delivery system (with or without Timolol).

               2. Assignments. B&L and InSite hereby agree to make any
assignments necessary to accomplish the foregoing ownership provisions. In
addition, each party will have the exclusive right to, and, at its expense, the
other party agrees to assist in every proper way (including, without limitation,
becoming a nominal party) to evidence, record and perfect any such assignments
and to apply for and obtain recordation of and from time to time enforce,
maintain, and defend such proprietary right.

         F. Confidentiality. InSite and B&L shall keep any Proprietary
Information or other business information provided or made available by the
other party or its Affiliates hereunder confidential, and neither InSite nor B&L
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 Proprietary
Information or other 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 (iv) 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 Proprietary
Information or other business information by InSite or B&L:

                    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 Regulatory Approval or
Payment Approval or other necessary governmental authorization for the clinical
testing or marketing of the Timolol Product or of prosecuting or defending
litigation.


                                      15.
   16
               Notwithstanding the foregoing, all Proprietary Information
related to a matter assigned to a party hereunder pursuant to Section E shall be
deemed Proprietary Information of the assignee and exceptions (i) through (iv)
set forth above will not be applicable thereto.

         G. Limited Liability.

            1. Incidental and Consequential Damages. NEITHER PARTY WILL BE
LIABLE UNDER ANY CONTRACT, NEGLIGENCE, STRICT LIABILITY OR OTHER THEORY FOR ANY
INCIDENTAL OR CONSEQUENTIAL DAMAGES WITH RESPECT TO ANY SUBJECT MATTER OF THIS
AGREEMENT.

            2. Limited Liability. NEITHER PARTY WILL BE LIABLE WITH RESPECT TO
ANY SUBJECT MATTER OF THIS AGREEMENT UNDER ANY CONTRACT, NEGLIGENCE, STRICT
LIABILITY OR OTHER THEORY FOR COST OF PROCUREMENT OF SUBSTITUTE GOODS, SERVICES,
TECHNOLOGY OR RIGHTS OR FOR ANY AMOUNTS AGGREGATING IN EXCESS OF AMOUNTS PAID TO
IT HEREUNDER.

         H. Term and Termination.

            1. Term. Unless terminated earlier as provided below or elsewhere in
this Agreement, this Agreement shall have a term extending from the Effective
Date to the later of: (i) the expiration of the last Patent, or (ii) ten (10)
years from the date the Timolol Product was first commercially sold in the last
country in which it is commercially exploited. Provided, that B&L shall have the
right upon 180 days written notice to InSite, to renew the provisions of this
Agreement relating to the license granted hereunder, and the payment of
royalties therefor, for an unlimited number of five (5) year terms (each a
"Renewal Term"). B&L shall have the right to terminate any Renewal Term upon 180
days prior written notice to InSite.

            2. Termination by Either Party for Cause. This Agreement may be
terminated by either party for cause immediately upon the occurrence of any of
the following events:

               a. If the other ceases to do business, or otherwise terminates
its business operations;

               b. If the other shall fail to promptly secure or renew any
license, registration, permit, authorization or approval which materially
affects the conduct of its business in the manner contemplated by this Agreement
in any Major Market Country or if any such license, registration, permit,
authorization or approval is revoked or suspended and not reinstated within
sixty (60) days (or if the applicable authority revoking or suspending such
license, registration, permit, authorization or approval does not, in its
ordinary course, reinstate such license, registration, permit, authorization or
approval within sixty (60) days, then the party shall exercise its diligent
efforts to have such license, registration, permit, authorization or approval

                                      16.
   17
reinstated, and so long as such party is diligently pursuing reinstatement of
such license, registration, permit, authorization or approval, and it can
reasonably be assumed that such license, registration, permit, authorization or
approval will be reinstated in due course, then such failure to obtain
reinstatement will not be grounds for termination of this Agreement (this clause
applies solely on a country-by-country basis);

               c. If the other materially breaches any material provision of
this Agreement and fails to cure such breach within sixty (60) days (twenty (20)
days in the case of a failure to pay any amounts due hereunder) of notice
describing the breach, provided, however, that if such a cure can be achieved
and the breaching party is diligently pursuing a cure, then such a breach shall
not be grounds for termination of this Agreement; or

               d. If the other shall seek protection under any bankruptcy,
receivership, trust deed, creditors arrangement, or comparable proceeding, or if
any such proceeding is instituted against the other (and not dismissed within
one hundred and twenty (120) days).

         3. Termination by Either Party for Other Reasons.

            a. In the event that either party hereto assigns any part of this
Agreement, by operation of law or otherwise, except as specifically permitted
under this Agreement, it shall notify the other party hereto at least thirty
(30) days prior to such assignment, and the other party shall have thirty (30)
days from the date of such notice to terminate this Agreement, effective
immediately upon receipt of such notice. Failure to give such notice within such
thirty (30) day period shall be deemed to be a waiver of such party's
termination right under this Section H.3. with respect to such assignment.

            b. B&L shall have the right to terminate this Agreement if, in the
reasonable discretion of B&L, the results of Phase II clinical testing of the
Timolol Product indicate that the FDA is unlikely to eventually approve the
Timolol Product for marketing and sale in the United States. In the event B&L
terminates this Agreement pursuant to this Section H.3.b., all rights to the
Timolol Product shall revert to InSite and Insite shall be free to fully
exploit, without approval or accounting, all of the information developed
hereunder with respect to the Timolol Product.

         4. Effect of Termination. The following provisions shall survive the
termination of this Agreement, and any extensions thereof: Sections D.3 (to the
extent inventories of the Timolol Product in existence upon the date of
termination are sold in any country after termination of this Agreement), E, F,
H.4., I, and K.4, K.6, K.7, K.8, K.9 and K.13. Remedies for breaches will also
survive. Each party will promptly return all Proprietary Information of the
other (and all copies and abstracts thereof) that it is not entitled to use
under the surviving terms of this Agreement. Termination of this Agreement with
respect to the Timolol Product in a particular country shall have the same
effect as termination of this entire Agreement, but with respect to such country
only.


                                      17.
   18
               5. Termination Not Sole Remedy. Termination is not the sole
remedy under this Agreement and, whether or not termination is effected, all
other remedies will remain available.

         I. Indemnity.

            1. Joint Indemnification Obligations. Each party shall defend,
indemnify and hold the other party, any Affiliate of the other party, any
officer, director or employee of such other party or of any of its Affiliates
(individually, an "Exculpated Party") harmless from and against any claim,
action, damage, loss, liability or expense (including, without limitation,
reasonable attorneys' fees, settlement costs, litigation costs and costs on
appeal regardless of outcome) ("Claims") incurred or suffered by any Exculpated
Party due to: (a) the material breach of any covenant or agreement by such
party; (b) any material misrepresentation or breach of warranty made by such
party pursuant to this Agreement; (c) any claim arising from the gross
negligence or intentional misconduct of such party; or (d) the operations or
activities of such party's Affiliates, licensees or sublicensees in material
contravention of the requirements of this Agreement (and such party shall
terminate immediately any such sublicense where a breach of its obligations by a
sublicensee cannot be readily compensated through monetary damages). In
addition, B&L and InSite each specifically acknowledge and shall comply with
their respective indemnification obligations set forth in that certain
Manufacturing and Supply Agreement between B&L and InSite of even date herewith,
which indemnification obligations are hereby incorporated by reference herein.

            2. Patent Indemnity. InSite shall defend and hold B&L and its
officers, directors, agents and employees harmless from any claim or liability
resulting from infringement by DuraSite of any United States patent issued as of
the date of approval of the Timolol Product by the FDA for sale in the United
States or, if no FDA approval is required, upon Commercial Launch in the United
States, provided InSite is promptly notified in writing of any and all threats,
claims and proceedings related thereto. InSite and B&L shall confer promptly (in
no event more than five (5) days after receipt by either party of such threat,
claim or proceeding) to discuss any such threats, claims or proceedings. InSite
shall have the exclusive authority to evaluate, defend and settle such patent
claim or litigation. After such discussions, InSite at its own expense and
option may then (i) settle or defend such claim, (ii) procure for B&L the right
to sell the Timolol Product, (iii) modify the Timolol Product to avoid
infringement, (iv) request B&L to cease further sale of the Timolol Product, or
(v) do any combination of the above. B&L shall provide InSite with assistance
and all relevant information necessary to pursue any such action.

            3. Notice of Claim for Indemnification. The indemnities of Sections 
I.1 and I.2 above shall not apply (i) if the indemnified party fails to give the
indemnifying party prompt notice of any Claim it receives and such failure
materially prejudices the indemnifying party, or (ii) unless the indemnifying
party is given the opportunity to approve any settlement, which approval shall
not be unreasonably withheld. Furthermore, the indemnifying party shall not be
liable for attorneys' fees or expenses of litigation of the indemnified party
unless the indemnified 

                                      18.
   19
party gives the indemnifying party the opportunity to assume control of the
defense or settlement. In addition, if the indemnifying party assumes such
control, it shall only be responsible for the legal fees and litigation expenses
of the attorneys it designates to assume control of the litigation. However, in
no event shall the indemnifying party assume control of the defense of the
indemnified party without the consent of the indemnified party (which consent
shall be given or not at its sole discretion).

         J. Maintenance and Enforcement of Patents.

            1. Maintenance and Enforcement. InSite shall undertake and shall
bear all costs of the prosecution and maintenance of the Patents in the
Territory. InSite shall employ reasonable efforts to keep B&L fully and timely
informed with respect to the course and conduct of patent application
prosecution matters within the scope of the Patents.

            2. Termination of Prosecution or Maintenance. If InSite elects to
terminate either the prosecution or maintenance of any of the Patents 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 B&L sixty (60)
days prior written notice of such election prior to any time limit on any action
due. B&L, upon receipt of such notice, shall have the option to undertake the
continuation of such prosecution or maintenance and InSite will transfer title
to B&L for such patent application or patent.

            3. Infringement of Patents.

                a. If either party shall become aware of any infringement or
threatened infringement of any Patents, including that contained in a notice
provided under the 1984 Act, then the party having such knowledge shall give
notice to the other within ten (10) days of becoming aware of such infringement
or threatened infringement.

                b. InSite shall have the first right but not an obligation to
bring an enforcement action or to take any other reasonable steps to defend the
Patents against infringement and B&L shall in such event give all reasonable
assistance to InSite with respect to patent and legal questions. The costs of
such patent enforcement shall be borne by InSite. If InSite does not commence a
particular infringement action within ninety (90) days after it has received
notice of such infringement, B&L, after notifying InSite in writing, shall be
entitled to bring such infringement action or other appropriate action or claim
at its own expense but shall request in writing that InSite fund 50% of such
expenses. If InSite declines to pursue such action or fails to respond to B&L
within sixty (60) days after receipt of B&L's notice that it will do so, B&L
shall have the right to undertake such action and if InSite fails to fund 50% of
B&L's expenses in pursuing such action, then B&L shall be entitled to 100% of
all recoveries and B&L shall no longer be required to pay royalties to InSite
for the Timolol Product in the country in which such action was prosecuted.
Recovery from any settlement or judgement from any such action in the Territory
either pursued by InSite or co-funded by InSite shall go first to reimburse the
expenses of the parties and the remainder shall be shared by the parties on a



                                      19.
   20
50%/50% basis. Notwithstanding the foregoing, if the monetary recovery is less
than the out-of-pocket expenses of InSite and B&L, reimbursement shall be on a
pro rata basis, based upon cost incurred. In any event, InSite and B&L shall
assist one another and reasonably cooperate in any such litigation at the
other's request without expense to the requesting party.

                c. If InSite and B&L, after consultation with each other, elect
not to bring suit, individually or jointly, or if InSite and B&L, as the case
may be, are/is not able to stop such infringing activities in any country, the
applicable royalty for such country shall be adjusted as set forth in Section 
B.4.a, if at all.

         K. General.

            1. Amendment and Waiver. Except as otherwise expressly provided
herein, any provision of this Agreement may be amended and the observance of any
provision of this Agreement may be waived (either generally or in any particular
instance and either retroactively or prospectively) only with the written
consent of the parties. However, it is the intention of the parties that this
Agreement be controlling over additional or different terms of any purchase
order, confirmation, invoice or similar document, even if accepted in writing by
both parties, and that waivers and amendments shall be effective only if made by
non-pre-printed agreements clearly understood by both parties to be an amendment
or waiver. The failure of either party to enforce its rights under this
Agreement at any time for any period shall not be construed as a waiver of such
rights.

            2. Dispute Resolution. Except that either party may seek equitable
relief from a court, if any dispute arises between InSite and B&L with respect
to the interpretation or breach of this Agreement, either party shall notify the
other of the dispute in writing and shall attempt to resolve the dispute through
discussions between InSite's Chief Executive Officer and B&L's President. If
such officers are unable to resolve the dispute within thirty (30) days after
the date written notice of the dispute is delivered, the parties shall seek to
resolve the dispute by initiating an Alternative Dispute Resolution ("ADR") in
which the Judicial Arbitration and Mediation Services ("JAMS"), Oakland,
California shall select the mediator. Such mediator shall hold a hearing to
resolve the dispute within sixty (60) days of his or her selection. The location
of the hearing shall be Oakland, California. Each party may be represented by
counsel and shall have the right to make a presentation of evidence at such
hearing. The mediator shall render a disposition on the proposed rulings as
expeditiously as possible but not later than fifteen (15) days after the
conclusion of the hearing. If the parties are unable to resolve the dispute, the
dispute may, upon the agreement of the parties, be settled by arbitration. If
the parties agree to arbitrate the dispute, such arbitration shall take place in
Alameda County, California in accordance with the then current commercial
arbitration rules of the American Arbitration Association and judgment upon the
award rendered by the Arbitrator(s) shall be binding on the parties and may be
entered by either party in the court or forum, state or federal, having
jurisdiction. Notwithstanding anything to the contrary nothing in this Agreement
shall be deemed as preventing either party from seeking injunctive relief (or
any other provisional remedy) from any court having jurisdiction over the
parties and the subject matter of the dispute

                                      20.
   21
as necessary to protect either party's name, proprietary information, trade
secrets, know-how or any other proprietary rights. Further, in the event the
parties do not agree to arbitrate any dispute hereunder, either party may seek
such other remedy, at law or in equity, as it may deem necessary or appropriate.

         3. Governing Law; Attorneys' Fees; Legal Actions. This Agreement shall
be governed by and construed under the laws of the State of California without
regard to conflicts of laws provisions thereof. In any action or proceeding to
enforce rights under this Agreement, including without limitation, any
arbitration, the prevailing party shall be entitled to recover costs and
attorneys' fees.

         4. Headings. Headings and captions are for convenience only and are not
to be used in the interpretation of this Agreement.

         5. Notices. Any and all notices or other communications required or
permitted under this Agreement must be in written form by facsimile
transmission, or mailed postage prepaid by first class certified or registered
mail, or sent by a nationally recognized express courier service or hand

         6. Entire Agreement. This Agreement supersedes all proposals, oral or
written, all negotiations, conversations, or discussions between or among
parties relating to the subject matter of this Agreement and all past dealing or
industry custom.

         7. Severability. If any provision of this Agreement is held to be
illegal or unenforceable, that provision shall be limited or eliminated to the
minimum extent necessary so that this Agreement shall otherwise remain in full
force and effect and enforceable.

         8. Relationship of Parties. The parties hereto expressly understand and
agree that the other is an independent contractor in the performance of each and
every part of this Agreement, and is solely responsible for all of its employees
and agents and its labor costs and expenses arising in connection therewith.
Nothing in this Agreement shall be construed to give either party the power or
authority to act for, bind or commit the other party.

         9. Assignment. This Agreement and the rights hereunder are not
transferable or assignable, except as specifically permitted in this Agreement,
without the prior written consent of the parties hereto, except for rights to
payment and except to a person or entity who acquires all or substantially all
of the assets, capital stock or business of a party, whether by sale, merger or
otherwise.

         10. Publicity, Press Releases and Terms of Agreement. Except to the
extent necessary under applicable laws or for ordinary marketing purposes, the
parties agree that (i) no press releases or other publicity relating to the
substance of the matters contained herein will be made without joint approval,
and (ii) the terms of this Agreement shall be treated by each party as
Proprietary Information. A press release announcing this Agreement will be
jointly developed and released by the parties.

         11. Force Majeure. No liability or loss of rights hereunder shall
result to either party from delay or failure in performance (other than payment)
caused by force majeure, that is, circumstances beyond the reasonable control of
the party affected thereby, including, without limitation, acts of God, fire,
flood, war, government action, compliance with laws or regulations, strikes,
lockouts or other serious labor disputes, or shortage of or inability to obtain
material or equipment.

         12. Remedies. Except as otherwise expressly stated in this Agreement,
the rights and remedies of a party set forth herein with respect to failure of
the other to comply with 

                                      22.
   23
the terms of this Agreement (including, without limitation, rights of full
termination of this Agreement) are not exclusive, the exercise thereof shall not
constitute an election of remedies and the aggrieved party shall in all events
be entitled to seek whatever additional remedies may be available in law or in
equity.
