3. PATENT LICENSES.

     3.1 Definitions.  For purposes of this Agreement, the following terms shall
have the following respective meanings unless the context dictates otherwise.

     (a) "Field" shall mean the prevention,  diagnosis,  control or treatment of
any human or animal disease or condition by use of a Licensed Product(s), either
as a single agent or in combination with any other therapy.

     (b) "First  Commercial  Sale"  shall  mean,  with  respect to any  Licensed
Product,  the first sale for use or  consumption  by the general  public of such
Licensed Product in a country after all required marketing and pricing approvals
have been granted, or otherwise permitted,  by the governing health authority of
such country. "First Commercial Sale" shall not include the sale of any Licensed
Product  for use in  clinical  trials  or for  compassionate  use  prior  to the
approval of an NDA;  provided,  however,  that if and to the extent that OXiGENE
receives  remuneration  for any such  compassionate  use or named patient sales,
OXiGENE shall pay royalties thereon in accordance with Section 3.7.

                                      -3-


     (c)  "Licensed   Patents"   shall  mean  the  letters   patent  and  patent
applications  set  forth  on the  attached  Exhibit  C,  as  well as any and all
substitutions,   extensions,  renewals,  continuations,   continuations-in-part,
divisions,  patents-of-addition  and/or reissues  thereof and all foreign and/or
PCT counterparts thereto.

     (d)  "Licensed   Product"  shall  mean  any   pharmaceutical   product  the
manufacture,  sale  or  use  of  which  in  the  jurisdiction  in  which  it  is
manufactured or sold is covered by a Valid Claim of any Licensed Patent.

     (e) "Major Market" shall mean [*********************************].

     (f) "Net Sales" shall mean, with respect to any Licensed Product, the gross
amount invoiced to third parties by OXiGENE, its Affiliates or its sublicensees,
as the case  may be,  for  such  Licensed  Product,  commencing  with the  First
Commercial   Sale   of   such   Licensed    Product,    less   deductions   for:
[************************************************************]    Such   amounts
shall be determined from the books and records of [***********],  its Affiliates
or its  sublicensees,  as the case may be,  maintained  in  accordance  with the
generally accepted accounting principles, consistently applied.

     Notwithstanding  the foregoing,  in the event a Licensed Product is sold in
conjunction with another  proprietary active component so as to be a combination
product (whether packaged together or in the same therapeutic formulation),  Net
Sales  shall be  calculated  by  multiplying  the Net Sales of such  combination
product by a fraction,  the numerator of which shall be the fair market value of
the  Licensed  Product as if sold  separately  (determined  in  accordance  with
generally accepted accounting principles), and the denominator of which shall be
the aggregate fair market value of all the proprietary active components of such
combination product,  including the Licensed Product, as if sold separately.  In
the event no such  separate  sales are made by OXiGENE,  its  Affiliates  or its
sublicensees,  Net Sales of the  combination  product  shall be  calculated in a
manner to be negotiated  and agreed upon by the parties,  reasonably and in good
faith, prior to any sale of such combination product,  which shall be based upon
the respective  estimated commercial values of the proprietary active components
of such combination product.

     Notwithstanding  the  foregoing,  in connection  with (X) any sale or other
disposition of Licensed Product that is not a bona fide, arms length transaction
for money,  or (Y) any other use of Licensed  Product that does not result in or
give rise to sales  revenue  that is  customary in the country in which such use
takes  place  (except as  provided  in the next  paragraph),  Net Sales shall be
calculated  at the relevant open market price in the country in which such sale,
disposition   or  use  takes  place,   or,  if  such  price  is  not  reasonably
ascertainable,  at a reasonable price, assessed on an arms length basis, for the
goods and/or services received in consideration of the sale,  disposition or use
of Licensed Product.

     OXiGENE's or any of its Affiliate's transfer of Licensed Product to another
Affiliate  or a  sublicensee  shall not  result in any Net  Sales,  unless  such
Licensed  Product is consumed by such  Affiliate or sublicensee in the course of
its commercial  activities.  In such case, Net Sales shall occur upon such other
Affiliate's  or  sublicensee's  sale of such Licensed  Product to a third party.
Further, the disposition of Licensed Product for, or the use of Licensed Product
in,  pre-clinical  or clinical  (Phase I - III)  trials or other  market-focused
(Phase IV or V) trials or free samples shall not result in any Net Sales.

     (g) "Valid Claim" shall mean (i) a pending claim in any patent  application
that has not been  pending  for more  than  five  years,  or (ii) a claim of any
issued  letters  patent  that,  in each  case,  has not  been  held  invalid  or

                                      -4-


unenforceable  by final  decision  of a court or other  governmental  agency  of
competent  jurisdiction,  unappealable or unappealed within the time allowed for
appeal, and that is not admitted to be invalid or unenforceable through reissue,
disclaimer or otherwise.

in connection  with any such  sublicensing.  OXiGENE shall promptly  provide BMS
with notice of any sublicense granted hereunder.

     (b) OXiGENE hereby unconditionally guarantees the performance of any of its

this  Agreement,  BMS shall be entitled to proceed against either such Affiliate
or sublicensee  or directly  against  OXiGENE,  as BMS may determine in its sole
discretion, to enforce this Agreement.

     3.5 License Fees.

     (a) In partial  consideration of the rights and licenses granted to OXiGENE
under this Section 3 (collectively,  the "Licenses"),  within [*****] days after
the  execution  of  this  Agreement  OXiGENE  shall  pay  BMS a  non-refundable,
non-creditable  initial  license  fee in the  amount  of  [**********].  OXiGENE
acknowledges  that  the  amount  payable  under  this  Section  3.5(a)  has been

          (i)  [********] upon the issuance of the first notice of allowance, in
               any  Major  Market,  with  respect  to any  claim of U.S.  patent
               application   [********]  or  any   substitution,   continuation,
               continuation-in-part,  division,  patent-of-addition,  or foreign
               counterpart to any of the foregoing that covers the  [**********]

               continuation-in-part,  division,  patent-of-addition,  or foreign
               counterpart  to any of the foregoing  that covers the  [********]
               and/or any pharmaceutical composition thereof.

Each  of the  foregoing  payments  shall  be  made  within  [*****]  days  after

made any of the foregoing payments with respect to any claim, OXiGENE shall have
no further obligation to make such payment with respect to any other claim.

                                      -6-


     3.7 Royalties.

     (a) In  partial  consideration  of the  Licenses,  OXiGENE  shall pay BMS a
royalty  on Net  Sales  of  each  Licensed  Product,  commencing  on  the  First
Commercial  Sale of each  Licensed  Product by OXiGENE,  its  Affiliates  or its
sublicensees, in an amount equal to [****] percent of the [**********] Net Sales
of such Licensed Product by OXiGENE,  its Affiliates and its sublicensees during
the term of this Agreement.

     (b) The  obligation  to pay  royalties  to BMS under  this  Section  3.7 is
imposed only once with respect to the same unit of Licensed Product,  regardless
of the number of Licensed Patents pertaining thereto.

     3.8 Payment and Reports.

     (a) Except as otherwise  provided in this Agreement,  all royalty and other
payments due hereunder  shall be paid quarterly  within [***] days after the end
of each calendar quarter. Each such payment shall be accompanied by a statement,
Licensed  Product-by-Licensed  Product and country-by-country,  of the amount of
Net Sales during such quarter and the amount of royalties due on such Net Sales.

     (b)  OXiGENE  shall make all  payments  required  under this  Agreement  as
directed by BMS from time to time, in U.S. Dollars.  All royalties due hereunder
shall first be  determined  in the currency of the country in which the Licensed
Products in question were sold and then converted into  equivalent  U.S.  funds.
The  exchange  rate for such  conversion  shall be that rate  quoted in The Wall
Street Journal on the last business day of the applicable reporting period.

     (c) OXiGENE,  its Affiliates and its  sublicensees  shall keep complete and
accurate  records  pertaining to the sale of Licensed  Products and covering all
transactions  from which Net Sales are derived for a period of [*****] after the
year in which such sales  occurred,  and in  sufficient  detail to permit BMS to
confirm the accuracy of royalty payments due hereunder.

     (d) At the request and expense (except as provided below) of BMS,  OXiGENE,
its  Affiliates  and its  sublicensees  shall permit an  independent,  certified
public  accountant  appointed by BMS and  reasonably  acceptable to OXiGENE,  at
reasonable  times and upon reasonable  notice,  to examine those records and all
other material  documents relating to or relevant to Net Sales in the possession
or control of OXiGENE, its Affiliates or its sublicensees, for a period of three
years after such  royalties  have accrued.  The results of any such  examination
shall be made  available to both parties.  If, as a result of any  inspection of
the books and records of OXiGENE,  its  Affiliates  or its  sublicensees,  it is
shown that  OXiGENE's  royalty  payments under this Agreement were less than the
amount  which  should  have been paid,  then  OXiGENE  shall  make all  payments
required to eliminate any discrepancy  revealed by said inspection  within [***]
days after BMS' demand therefor.  Furthermore, if the aggregate royalty payments
OXiGENE  made were less than  [*****] of the amount  which should have been paid
during  the  period  in  question,  OXiGENE  shall  also  reimburse  BMS for the
reasonable  out-of-pocket  cost of such inspection and shall pay interest on the
deficiency pursuant to Section 3.8(g).

     (e) In the event that OXiGENE is required to withhold any tax to the tax or
revenue  authorities in any country in connection with any payment to BMS due to
the laws of such  country,  such amount  shall be  deducted  from the royalty or
other  payment to be made by OXiGENE,  and OXiGENE shall notify BMS and promptly
furnish BMS with copies of any tax certificate or other documentation evidencing
such  withholding.  Each  party  agrees to  cooperate  with the  other  party in
claiming  exemptions from such deductions or withholdings under any agreement or
treaty from time to time in effect.

                                      -7-


     (f) If at any time legal  restrictions  prevent OXiGENE's prompt remittance
of part or all of the royalties due with respect to any country where a Licensed
Product is sold,  OXiGENE shall  convert the amount owed to BMS into U.S.  funds
and shall pay BMS directly from  OXiGENE's  U.S.  source of funds for the amount
impounded. OXiGENE shall then pay all future royalties due to BMS from OXiGENE's
U.S.  source of funds so long as the legal  restrictions  of this Section 3.8(f)
still apply.

     (g) In the event that any payment  OXiGENE is required to make hereunder is
not made within  [********] after such payment was originally due, OXiGENE shall
pay interest on the past due amount as follows at the rate of [*****] per annum,
until payment in full is made.

     3.9 Intellectual Property Matters; Prosecution of Licensed Patents.

     (a)  From  and  after  the   Effective   Date   OXiGENE   shall  have  sole
responsibility for preparing, filing, prosecuting, maintaining and enforcing all
Licensed Patents, at its sole cost and expense.  Following the execution of this
Agreement the parties shall make  arrangements for the prompt,  orderly transfer
to OXiGENE of all files,  papers and  information in BMS' possession and control
relating to the Licensed Patents.

     (b)  In  the  event  that  OXiGENE  wishes  to  abandon  the   prosecution,
maintenance or  enforcement  of any Valid Claim(s) of any Licensed  Patent other
than in the  ordinary  course of  agreeing  on the  language  of claims with any
patent  office,  it shall  promptly  notify  BMS of such wish and  shall,  if so
requested by BMS, execute an instrument canceling the license granted to OXiGENE
under  this  Section  3 with  respect  to  such  Valid  Claim(s)  and  expressly
permitting BMS to continue such prosecution,  maintenance and/or enforcement, at
BMS' sole cost and expense.

     (c)  OXiGENE  shall have sole  responsibility  for  defending  against,  or
otherwise disposing of, any claim of, or action for, infringement of any patents
owned or licensed by third parties which is threatened,  made or brought against
either  party by  reason  of  OXiGENE's,  or its  Affiliates'  or  sublicensees'
exploitation  of the rights granted to OXiGENE under this Agreement or by reason
of the manufacture,  use or sale of any Licensed  Products;  provided,  however,
that OXiGENE shall not have any such responsibility with respect to any claim or
action to the extent it arises from BMS' exploitation of any of its interests in
the Licensed Patents prior to or after the Effective Date.

     (d) At  OXiGENE's  request,  BMS shall  provide  reasonable  assistance  to
OXiGENE in the  activities  set forth in Sections  3.9(a),  3.9(c) and  3.10(a),
including by providing  access to personnel and records of BMS pertaining to the
Licensed  Patents,  provided  that the  rendering  of such  assistance  does not
unreasonably interfere with the conduct of BMS' business in the ordinary course.

     3.10 Patent Enforcement.

     (a) OXiGENE  shall have the right,  but not the duty,  to institute  patent
infringement   actions  against  third  parties  with  respect  to  any  alleged
infringement  of  the  Licensed  Patents.  BMS  shall  execute  all  reasonable,
necessary and proper  documents  and take such  reasonable  actions  (other than

                                      -8-


allowing itself to be named as a party in any litigation or alternative  dispute
resolution  proceeding,  and  provided  that the taking of such actions does not
require  BMS to  expend  more  than  incidental  sums  of  money  and  does  not
unreasonably interfere with the conduct of BMS' business in the ordinary course)
as shall be appropriate to allow OXiGENE to institute and prosecute infringement
actions under this Section 3.10.

     (b) The costs and expenses of bringing  and  maintaining  any  infringement
action under Section 3.10(a) shall be borne solely by OXiGENE. To the extent BMS
agrees to take any action  pursuant  to Section  3.10(a)  that  requires  BMS to
expend more than incidental sums of money, OXiGENE shall reimburse BMS therefor,
promptly after receiving an invoice(s) from BMS.

     (c) Any  award or  compensation  (including  the fair  market  value of any
non-monetary compensation) paid by third parties as a result of any infringement
action brought by OXiGENE under Section 3.10(a) (whether by way of settlement or
otherwise) shall be allocated first to reimbursement of OXiGENE for all expenses
incurred  by  it  in  connection  with  such  action.  Any  remaining  award  or
compensation  shall be  allocated  to OXiGENE;  provided,  however,  that to the
extent  any such  award or  compensation  (including  the fair  market  value of
non-monetary compensation) shall relate to the sale of any compounds or products
that infringe upon any Licensed  Patent  (and/or to lost revenue or profits with
respect to any Licensed  Product),  then OXiGENE shall pay BMS a royalty thereon
in substantial  accordance with Section 3.7, the exact amount of such royalty to
be calculated in a manner agreed upon by the parties.

     3.11 Indemnification by OXiGENE.

     (a)  OXiGENE  shall  indemnify  and hold BMS and its  Affiliates  and their
respective directors,  officers, employees and agents, harmless from and against
any and all  liabilities,  damages,  losses,  costs and expenses  (including the
reasonable  fees of  attorneys  and other  professionals  and  other  reasonable
litigation expenses) arising out of or resulting from:

          (i)  the  negligence,   recklessness  or  intentional   misconduct  of
               OXiGENE,  its Affiliates or its sublicensees and their respective
               directors,  officers,  employees and agents,  in connection  with
               OXiGENE's exercise of any of its rights hereunder;

          (ii) any  and  all  product   liability   claims  resulting  from  the
               development and/or  commercialization  of any Licensed Product by
               OXiGENE, its Affiliates or its sublicensees; or

          (iii)any warranty claims,  Licensed Product recalls or any tort claims
               of personal injury  (including death) or property damage relating
               to or arising out of the manufacture,  use,  distribution or sale
               of  any  Licensed  Product  by  OXiGENE,  its  Affiliates  or its
               sublicensees  due to any negligence,  recklessness or intentional
               misconduct by, or strict liability of, OXiGENE, its Affiliates or
               its  sublicensees,  and  their  respective  directors,  officers,
               employees and agents,  except,  in each case, to the  comparative
               extent such claim arose out of or resulted  from the  negligence,
               recklessness  or intentional  misconduct of BMS or its Affiliates
               and their respective directors, officers, employees and agents.

For the  avoidance  of  doubt,  it is  acknowledged  that (a)  except  as may be
otherwise provided in the License Agreement, OXiGENE shall have no obligation to
indemnify BMS for any claims  resulting from,  arising out of or relating to the
conduct of any  clinical  trial by BMS;  and (b) BMS'  obligation  to  indemnify
OXiGENE for any such claim under  Section  14.1 of the License  Agreement  shall
continue in effect.

                                      -9-


     (b) In the event that any person  entitled  thereto  (an  "indemnitee")  is
seeking  indemnification  under Section  3.11(a),  such indemnitee  shall inform
OXiGENE  of a claim  as soon as  reasonably  practicable  after  the  indemnitee
receives  notice of the claim,  shall  permit  OXiGENE to assume  direction  and
control of the  defense of the claim  (including  the sole right to settle it at
the sole  discretion of OXiGENE,  provided that such  settlement does not impose
any  material  obligation  on the  indemnitee  or BMS) and  shall  cooperate  as
requested  (at the expense of  OXiGENE) in the defense of the claim  (including,
without  limitation,  granting  OXiGENE limited access to pertinent  records and
making  persons  under such  indemnitee's  control  available  for interview and
testimony).

     (c) As the parties intend complete indemnification,  all costs and expenses
incurred by any  indemnitee  to enforce this Section 3.11 shall be reimbursed by
OXiGENE.

     3.12 Term; Termination.

     (a) The term of the Licenses  shall  commence as of the Effective Date and,
unless sooner terminated as provided hereunder, shall expire as follows:

               (i)  As to each Licensed  Product in each  country,  the Licenses
                    shall  expire upon the  expiration  of the last of the Valid
                    Claims of the  Licensed  Patents to expire  with  respect to
                    such Licensed Product in such country.

               (ii) The  Licenses  shall  expire  in  their  entirety  upon  the
                    termination of the all Valid Claims of all Licensed  Patents
                    with respect to all Licensed Products in all countries.

     (b)  Following  the  expiration  of the Licenses with respect to a Licensed
Product in a country  pursuant  to Section  3.12(a)(i),  OXiGENE  shall have the
royalty-free,  perpetual right to continue to make, have made, use, sell,  offer
for sale, have sold and export such Licensed Product in such country.  Following
the  expiration  of  all  Licenses  in  their   entirety   pursuant  to  Section
3.12(a)(ii), OXiGENE shall have the royalty-free, perpetual right to continue to
make,  have made,  use, sell,  offer for sale, have sold and export all Licensed
Products in all countries.

     (c) Each party shall have the right to terminate the Licenses,  upon notice
to the other party, in the event that such other party materially  defaults with
respect to any of its material  obligations  under this  Agreement  and does not
cure such  default  within  [********]  after the  receipt of a notice  from the
non-breaching  party specifying the nature of, and requiring the remedy of, such
default (or, if such default cannot be cured within such [*********]  period, if
the breaching  party does not commence and diligently  continue  actions to cure
same during such [********]  period).  Any termination  pursuant to this Section
3.12(c)  shall be without  prejudice to any of the  non-breaching  party's other
rights under this Agreement,  and in addition to any other remedies available to
it by law or in equity.

     (d) Provided that OXiGENE is not in material breach of any obligation under
this  Agreement  at the time of any  termination  of the  Licenses  pursuant  to
Section 3.12(c), OXiGENE shall have the right for one year thereafter to dispose
of all Licensed Product then in its inventory and to complete manufacture of and
dispose  of  any  work-in-progress  then  being  manufactured,  as  though  this
Agreement had not terminated. OXiGENE shall pay royalties thereon, in accordance
with  the  provisions  of this  Agreement,  as  though  this  Agreement  had not
terminated.

                                      -10-


     (e) Upon any termination of any of the Licenses,  all relevant  sublicenses
granted by OXiGENE under this Agreement shall terminate simultaneously, subject,
nevertheless, to Section 3.12(d).

     (f)  Termination,  relinquishment  or expiration of this  Agreement for any
reason shall be without  prejudice to any rights which shall have accrued to the
benefit of either party prior to such termination, relinquishment or expiration.
Such  termination,  relinquishment  or expiration shall not relieve either party
from  obligations  which are  expressly  indicated  to  survive  termination  or
expiration of this Agreement.

     (g) Termination,  relinquishment  or expiration of this Agreement shall not
terminate a party's  obligation  to pay all  royalties,  milestone  payments and
other  monetary  obligations  that  may  have  accrued  hereunder  prior to such
termination.  All of the parties' rights and obligations  under Sections 1, 2.3,
2.4(b), 2.5, 3.2(b), 3.4, 3.8, 3.11, 3.12(b),  (f) and (g), 4.3, 4.6, 4.12, 4.13
and 4.14 shall survive termination, relinquishment or expiration hereof.

     (a) This Agreement  shall be governed by and interpreted in accordance with
the  laws of the  State  of New  Jersey  without  regard  to its  choice  of law
principles;   provided,  however,  that  any  arbitration  proceeding  conducted
pursuant to Section 4.13 shall be governed by the Convention on the  Recognition
and  Enforcement  of  Foreign  Arbitral  Awards of June 10,  1958.  The  English
original of this Agreement shall prevail over any translation hereof.

     (b) Without  prejudice to the rights and  obligations  of the parties under
Section 4.13, each party hereby consents to the in personam  jurisdiction of any
state or  federal  court  sitting  in the State of New York with  respect to any
matter  arising in connection  with this  Agreement and further  consents to the
service of any process,  notice of motion or other application to any such court
or a judge thereof outside the State of New York by registered or certified mail
or personal  service,  provided that  reasonable time is allowed for appearance.
Each party hereby  waives,  to the greatest  extent it may do so, any defense it
may have on the  grounds of  inconvenient  forum  with  respect to any action or
proceeding maintained in any state or federal court in New York.

     (c) For purposes of consistency,  Section 17.15 of the License Agreement is

Agreement  shall be finally  settled by  arbitration to be held in New York, New
York, under the auspices and then current  commercial  arbitration  rules of the
American  Arbitration   Association  (the  "AAA").  Such  arbitration  shall  be
conducted by three  arbitrators.  Within 30 days after the  commencement  of any
arbitration,  each party shall appoint one arbitrator, and these two arbitrators
shall  jointly  appoint  the  third  arbitrator,   who  shall  have  significant
experience in pharmaceutical drug development and  commercialization;  provided,
however,  that if the two  arbitrators  appointed  by the  parties are unable to
agree upon the third arbitrator within 30 days after their appointment, then the
third  arbitrator shall be appointed by the AAA. The parties shall instruct such
arbitrators  to render a  determination  of any such dispute  within four months
after their  appointment.  All  arbitration  proceedings  shall be  conducted in
English.  Judgment  upon any award  rendered  may be entered in any court having
jurisdiction, or application may be made to such court for a judicial acceptance
of the award and an order of enforcement, as the case may be.

                                      -13-


     (b) Section  4.13(a)  shall not  prohibit a party from  seeking  injunctive
relief  from a court of  competent  jurisdiction  in the  event  of a breach  or
prospective  breach of this  Agreement  by the other  party  which  would  cause
irreparable harm to the first party.

     (c) For purposes of consistency,  Section 17.16(a) of the License Agreement
is  hereby   amended  to  replace  the  reference   therein  to   "Philadelphia,
Pennsylvania" with the words "New York, New York."

     4.14 No Consequential Damages. IN NO EVENT SHALL EITHER PARTY OR ANY OF ITS
RESPECTIVE AFFILIATES OR SUBLICENSEES BE LIABLE TO THE OTHER PARTY OR ANY OF ITS
AFFILIATES OR SUBLICENSEES  FOR SPECIAL,  INDIRECT,  INCIDENTAL OR CONSEQUENTIAL
DAMAGES, WHETHER IN CONTRACT,  WARRANTY,  TORT, NEGLIGENCE,  STRICT LIABILITY OR
OTHERWISE,  INCLUDING, BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE, OR CLAIMS
OF CUSTOMERS OF ANY OF THEM OR OTHER THIRD PARTIES FOR SUCH OR OTHER DAMAGES.

     4.15 Entire  Agreement.  Except as set forth in Section  1.3  hereof,  this
Agreement  (together with the Exhibits  hereto) sets forth the entire  agreement
and understanding between the parties as to the subject matter hereof and merges
all prior discussions and negotiations  between them, and neither of the parties
shall be bound by any conditions,  definitions,  warranties,  understandings  or
representations  with  respect to such  subject  matter  other than as expressly
provided  herein or as duly set forth on or subsequent to the Effective  Date in
writing and signed by a proper and duly authorized  officer or representative of
the party to be bound  thereby.  4.16  Parties  in  Interest.  All the terms and
provisions of this Agreement shall be binding upon,  inure to the benefit of and
be enforceable by the parties hereto and their respective  permitted  successors
and assigns.

     4.17 Descriptive  Headings.  The descriptive headings of this Agreement are
for  convenience  only,  and  shall be of no force or effect  in  construing  or
interpreting any of the provisions of this Agreement.

     4.18  Counterparts.  This Agreement may be executed  simultaneously  in two
counterparts,  any one of which need not contain the  signature of more than one
party,  but both such  counterparts  taken together shall constitute one and the
same agreement.

     4.19  Events  of Force  Majeure.  Neither  party  shall be held  liable  or
responsible to the other party nor be deemed to be in default under or in breach
of any  provision  of this  Agreement  for  failure  or delay in  fulfilling  or
performing any obligation under this Agreement when such failure or delay is due
to force majeure, and without the fault or negligence of the party so failing or
delaying.  For purposes of this  Agreement,  force  majeure  shall be defined as
causes beyond the control of the party, including,  without limitation,  acts of
God;  acts,  regulations,  or  laws of any  government;  war;  civil  commotion;
destruction of production  facilities or materials by fire,  flood,  earthquake,
explosion  or  storm;  labor  disturbances;  epidemic;  and  failure  of  public
utilities or common carriers.  In such event OXiGENE or BMS, as the case may be,
shall immediately notify the other party of such inability and of the period for
which such inability is expected to continue. The party giving such notice shall
thereupon be excused from such of its obligations  under this Agreement as it is
thereby  disabled  from  performing  for so long as it is so disabled and for 30
days thereafter. To the extent possible, each party shall use reasonable efforts
to minimize the duration of any force majeure.

                                    * * *

                                      -14-


     IN WITNESS  WHEREOF,  each of the Parties has caused this  Agreement  to be
