                  priority  of  the   parties  to  develop   and   commercialize
                  Product(s)  for the Field within the Major  Market  Countries.
                  Therefore,  DMI and ENHANCE agree, pursuant and subject to the
                  terms  of this  Agreement,  to  cooperate  with,  and  provide
                  reasonable  support for, each other in developing  Product(s),
                  with the goal of obtaining  Regulatory Approval for Product(s)

                  received  Regulatory  Approval for uses outside the Field,  so
                  that  Preclinical  Studies  and  Phase 1  Trials  need  not be
                  performed, and a Phase 2a Trial of such a DMI-9758-Product can
                  be commenced as soon as practicable after the Effective Date.

                  Development as soon as reasonably practicable.

         2.4      It is also the intent of DMI and ENHANCE to share the Revenues
                  obtained  as  a  result  of  the   commercialization,   sales,
                  licensing and  sublicensing of Product(s) for the Field within

                           other Product(s),  including  Indirect Costs, plus an
                           overhead  amount  to be  determined  as set  forth in
                           Subsection (e) of this Section 7.2.

                  (d)      Payment  of all costs for the Phase 2 Trials or Phase
                           2a and 2b Trials of any other  Product(s),  including
                           Indirect  Costs,   plus  an  overhead  amount  to  be
                           determined  as set  forth in  Subsection  (e) of this
                           Section 7.2.

                  (e)      An overhead  amount,  as a percentage of total costs,
                           shall  be  established  by  the  Steering   Committee
                           independently  for each activity for each year during
                           which the activity will be  performed.  Factors to be
                           considered by the Steering  Committee in establishing
                           the overhead amount include the type of activity, the
                           stage of the activity (E.G.,  whether the activity is
                           just beginning or is near completion),  whether it is
                           the first time that DMI has performed the activity, a
                           realistic and reasonable assessment of the commitment
                           of personnel and facilities that DMI must make to the
                           activity at each  stage,  etc.  However,  in no event
                           will the  overhead  amount be less than DMI's  actual
                           Overhead  plus 5% of  total  costs.  If the  overhead
                           amount established by the Steering Committee and paid
                           to DMI as provided in Subsection  (f) of this Section
                           7.2 is less than  DMI's  actual  Overhead  plus 5% of
                           total costs,  the  deficiency  will be paid to DMI as
                           also provided in Subsection (f) of this Section 7.2.

                  (f)      Payments  (a),  (b),  (c) and (d)  shall be made on a
                           periodic  basis  to be  determined  by  the  Steering
                           Committee,  but no less  than  quarterly.  Each  such
                           payment shall be that amount budgeted by the Steering
                           Committee for the upcoming period for activities (a),
                           (b), (c) and (d), including the appropriate  overhead
                           amount,  and each such payment shall be made at least
                           fifteen  (15) days prior to the  commencement  of the
                           upcoming period.  Any overage will be credited toward
                           the payment for the next period. Any deficiency shall
                           be added to the  payment for the next period or shall
                           be paid sooner if requested by DMI, in which case the
                           payment of the deficiency will be made within fifteen
                           (15) days after being requested by DMI.

                  (g)      DMI shall  keep  such  records,  books  and  accounts
                           showing  its  use  of  the   payments   specified  in
                           Subsections (a), (b), (c) and (d) of this Section 7.2
                           as the Steering Committee may require.

         7.3      Nothwithstanding  the  foregoing,  the  total of the  payments
                  specified in Subsections  (a), (b), (c) and (d) of Section 7.2
                  shall not exceed $12,500,000 ("Payment Cap"). Renegotiation of
                  the amount of the Payment Cap may be


                                       12



                  requested  by either party at any time during the first twelve
                  (12) months  following the Effective  Date. If a renegotiation
                  is requested, both parties agree to renegotiate in good faith.
                  The  renegotiated  amount of the Payment Cap shall be based on
                  the best  available  estimates of the costs of the  activities
                  contemplated  by  this  Agreement  and  on  a  reasonable  and
                  realistic  assessment of ENHANCE's  financial condition and of
                  the funding that ENHANCE will  reasonably  be able to provide.
                  In no  event,  however,  will  the  Payment  Cap be less  than
                  $6,000,000.

         7.4      Costs in excess of the Payment Cap which are necessary for the
                  research,     development     and     commercialization     of
                  DMI-7958-Product(s)   and/or  additional  Product(s)  will  be
                  shared  equally by the parties  and/or  funding to cover these
                  costs will be obtained from third parties.

                  (a)      If it becomes  necessary  for the  parties to provide
                           some  or all of  this  additional  funding,  and  DMI
                           cannot  contribute its equal share of this additional
                           funding,  then  ENHANCE  may elect to make up some or
                           all of the  deficiency.  In such a case, the Revenues
                           payments due to DMI under  Article 8 shall be reduced
                           from 50% to 35% and ENHANCE's Revenues payments under
                           Article  8 shall be  increased  from 50% to 65% until
                           such time as ENHANCE has been  reimbursed at the rate
                           of  $1.25  for  each  $1.00  of  additional   funding
                           provided by ENHANCE.

                  (b)      Similarly, if it becomes necessary for the parties to
                           provide  some or all of this  additional  funding and
                           ENHANCE  cannot  contribute  its equal  share of this
                           additional  funding,  then  DMI may  elect to make up
                           some or all of the  deficiency.  In such a case,  the
                           Revenues  payments  due to  ENHANCE  under  Article 8
                           shall be reduced  from 50% to 35% and DMI's  Revenues
                           payments  under Article 8 shall be increased from 50%
                           to 65% until such time as DMI has been  reimbursed at
                           the  rate of  $1.25  for  each  $1.00  of  additional
                           funding provided by DMI.


               Article 8. Sharing Of Revenues; Reports And Records

         8.1      ENHANCE  and DMI will share  equally  all  Profits on Sales of
                  Product(s)  for the Field in the Territory  made by either one
                  of them.  Payments of an equal share (I.E.,  50%) of a selling
                  party's  Profits  shall  be paid by the  selling  party to the
                  other  party for each  Calendar  Quarter in which  Profits are
                  made.  Payments  shall be due on or  before  thirty  (30) days
                  after the last day of a Calendar  Quarter in which Profits are
                  made. In the case of any delay in the payment,  interest at 2%
                  over the Prime Rate,  assessed from the thirty-first day after
                  the  last  day of the  Calendar  Quarter  until  the  date the
                  payment  is  received,  shall  be due.  Each  party  shall  be
                  responsible  for paying any and all taxes levied on account of
                  the payments it receives.


                                       13



         8.2      ENHANCE and DMI will share equally all payments  received from
                  licensees  and   sublicensees,   including   licensing   fees,
                  sublicensing fees, milestone payments and royalties.  Payments
                  of an equal  share  (I.E.,  50%) of a  payment  received  from
                  licensees and sublicensees  shall be made no later than thirty
                  (30) days after its  receipt.  In the case of any delay in the
                  payment, interest at 2% over the Prime Rate, assessed from the
                  thirty-first  day  after the  receipt  of the  payment  from a
                  licensee  or  sublicensee   until  the  date  the  payment  is
                  received,  shall be due. Each party shall be  responsible  for
                  paying any and all taxes  levied on account of the payments it
                  receives.

         8.3      All payments  shall be made by wire  transfer in United States
                  dollars  to  the  credit  of  such  bank  account  as  may  be
                  designated by the receiving  party to paying party in writing.
                  Any  payment  which  falls due on a date which is a  Saturday,
                  Sunday or a legal  holiday in the United States may be made on
                  the next  succeeding  day which is not a  Saturday,  Sunday or
                  legal holiday.

         8.4      Each party shall furnish or cause to be furnished to the other
                  party  on a  quarterly  basis  a  written  report  or  reports
                  covering  each Calendar  Quarter  (each such Calendar  Quarter
                  being sometimes referred to herein as a "reporting period") in
                  which  Profits are made and/or in which  payments are received
                  from  licensees  or  sublicensees  showing  (i)  Sales of each
                  Product in the  Territory  during the reporting  period,  (ii)
                  dispositions of Product(s)  other than by sale for cash, (iii)
                  calculation  of Profits for each Product  during the reporting
                  period, (iv) payments received from licensees and sublicensees
                  during the reporting period,  including, for royalty payments,
                  a report from the licensees  and/or  sublicensees  showing the
                  calculation of the  royalties,  (v) the exchange rates used in
                  converting  into  dollars from the  currencies  in which Sales
                  were made or payments  from  licensees and  sublicensees  were
                  received,   and  (vi)  any  other  information   necessary  to
                  establish  the  accuracy  and  completeness  of the  payments.
                  Reports  shall be due  thirty  (30) days after the end of each
                  Calendar  Quarter in which  Profits  are made  and/or in which
                  payments are received  from  licensees or  sublicensees.  If a
                  party does not make Profits or receive payments from licensees
                  or sublicensees in a Calendar Quarter, then that party will so
                  notify the other party.

         8.5      Each party  shall keep  accurate  and  consistent  records and
                  books of account  containing regular entries relating to Sales
                  and to the  manufacture  of  Product(s),  which  records shall
                  contain  all  information  necessary  for the  computation  of
                  Profits.  Such records shall be available for examination from
                  time to time,  including for a period of three (3) years after
                  termination of this Agreement, by representatives of the other
                  party  for  the  purpose  of  verifying  the  accuracy  of the
                  quarterly  reports  required  by  Subsection  8.4 and  Profits
                  computations.  Such  examination  shall be made during  normal
                  business  hours with  prior  notice.  Any such  representative
                  shall be entitled to make copies and extracts  from such books
                  and  records.  Each  party  shall  fully  cooperate


                                       14



                  with  such  examination  and  inspection  and  shall  give any
                  explanations that reasonably may be requested.

         8.6      Upon the written request of a party ("requesting  party"), and
                  not more  than once in each  calendar  year,  the other  party
                  ("audited party") will permit an independent  certified public
                  accounting  firm  of  recognized   standing  selected  by  the
                  requesting  party and  reasonably  acceptable  to the  audited
                  party to have access  during  normal  business  hours to those
                  records of the audited  party that may be  necessary to verify
                  the accuracy of the quarterly  reports  required by Subsection
                  8.4 and  calculations  of Profits  for any year ending no more
                  than 36 months prior to the date of such request.

                  (a)      The  accounting  firm will disclose to the requesting
                           party only whether the quarterly  reports and Profits
                           calculations  are correct or incorrect,  the specific
                           details   concerning  any   discrepancies,   and  the
                           corrected  amount of Sales and/or  Profits.  No other
                           information will be provided to the requesting party.

                  (b)      If the requesting party's independent accounting firm
                           determines  that  Profits  have  been  overpaid,  the
                           requesting  party  will repay the  audited  party the
                           overage  on the same date that the  requesting  party
                           delivers to the audited party such accounting  firm's
                           written report. If the requesting party's independent
                           accounting  firm  determines  that  Profits have been
                           underpaid,  the audited  party will pay the amount of
                           the additional  Profits plus interest  assessed at 2%
                           over the Prime Rate from the time(s)  the  payment(s)
                           was(were)   originally   due.   The  payment  of  the
                           additional  Profits and interest will be due no later
                           than  fifteen  (15) days  after the date on which the
                           requesting  party  delivers to the audited party such
                           accounting firm's written report.

                  (c)      The fees charged by the accounting  firm will be paid
                           by the requesting party,  provided that, if the audit
                           determines that the additional Profits payable by the
                           audited party to the requesting party for such period
                           exceed  5% of the  Profits  actually  paid,  then the
                           audited  party  will  pay  the  reasonable  fees  and
                           expenses charged by such accounting firm.

         8.7      Each party will treat all financial  information  of the other
                  party  subject to review under this  Article 8 as  Proprietary
                  Information  in  accordance  with  Article  16 hereof and will
                  cause  its  accounting   firm  to  enter  into  an  acceptable
                  confidentiality  agreement  obligating such accounting firm to
                  retain all such financial  information in confidence  pursuant
                  to the confidentiality and non-use provisions of Article 16.


                           Article 9.  Steering Committee


                                       15



         9.1      The parties hereby  establish a Steering  Committee to manage,
                  direct, supervise and coordinate, in accordance with the terms
                  of this Agreement,  all of the activities contemplated by this
                  Agreement, including (i) the development and commercialization
                  of  Product(s)  for the Field within the  Territory,  (ii) the
                  Additional  Research And Development,  and (iii) the licensing
                  or  acquisition  of Product(s)  as provided in Subsection  5.2
                  above.   In   particular,    but   without   limitation,   the
                  responsibilities of the Steering Committee will include:

                  meeting shall be determined  by the  Co-Chairpersons,  and the
                  time and location of subsequent  meetings shall be established
                  by the Steering  Committee.  Meetings may be held in person or

                  review and comment on all INDs and Drug Approval  Applications
                  prior to filing in  accordance  with  specific  time  lines or

         10.2     Regulatory  documents  for  each  filing  will  be  owned  and
                  centralized  and held at the  offices  of the party  primarily
                  responsible for such filing, but will be made available to the
                  other  party for use in  accordance  with this  Agreement.  No
                  party  shall  have the right to  transfer  title or  otherwise
                  attempt in any manner to dispose of any INDs or Drug  Approval
                  Applications  or otherwise  impair the other party's rights in
                  such INDs or Drug  Approval  Applications  without the written

                  each  party  shall  have the right to cross  reference  in any
                  regulatory   document,   the  INDs  and  other  Drug  Approval

                  parties may  participate in all  substantive  discussions  and
                  meetings with regulatory authorities.  The party not primarily
                  responsible for conducting the Clinical Trial will send only a
                  reasonable number of representatives to any such discussion or
                  meeting.

                  communication  shall notify the other party and provide a copy
                  of  any   written   communication   as  soon   as   reasonably
                  practicable.

         10.7     The party primarily  responsible for a Clinical Trial shall be
                  responsible for the prompt reporting of adverse  reactions (as
                  defined  by  the  World  Health   Organization)   directly  or
                  indirectly  attributable  to the use of the Product being used
                  in  the  Clinical  Trial  to  the   regulatory   authority  in
                  compliance with applicable law. After Regulatory Approval of a
                  Product, ENHANCE shall be responsible for the prompt reporting
                  of any adverse reactions  directly or indirectly  attributable
                  to the  use  of the  Product  to  the  appropriate  regulatory
                  authorities  in  compliance  with  applicable  law. Each party
                  shall  immediately  inform the other party of any adverse drug

         11.8     DMI shall  keep  ENHANCE  advised as to all  developments  and
                  shall  provide  ENHANCE  with all  materials  sufficiently  in
                  advance to allow  ENHANCE to review and  provide  input on any
                  proposed  filing  prior to its  filing,  which  input shall be
                  considered  in  good  faith  and  included  where   reasonably
                  possible by DMI. Notwithstanding the foregoing, DMI shall have
                  the right to take such actions as are reasonably necessary, in
                  its  good  faith  judgment,  to  preserve  all  rights  in its
                  Intellectual Property, and DMI shall notify ENHANCE as soon as
                  possible after taking any such action.

         11.9     DMI will abandon Intellectual  Property or any rights therein,
                  only  after  notice to ENHANCE  at least  thirty  (30) days in
                  advance and only after giving ENHANCE an opportunity to assume
                  responsibility    for   obtaining   and/or   maintaining   the
                  Intellectual Property protection proposed to be abandoned.

         12.1     DMI  hereby  grants to  ENHANCE  an  exclusive  license of all

                  Product(s) for the Field within the Territory  pursuant to the
                  terms of this Agreement.  The licensed  Intellectual  Property

                  patent  applications  corresponding  to  the  PCT  application
                  listed in Appendix A, any  patents  issuing  from any of these
                  patent  applications  anywhere in the world, any extensions or
                  reissues of such patents,  and the inventions described in any
                  and all such patent applications and patents.

         12.2     ENHANCE  shall  have the right to assign  its  rights to Third
                  Parties  with  the  approval  of DMI in  all  or  part  of the
                  Territory,  provided  the  assignee  agrees to  assume  all of
                  ENHANCE's   obligations   and   responsibilities   under  this
                  Agreement in all, or the assignee's part, of the Territory.


                     Article 13. Retention Of Rights By DMI


                                       21



         13.1     DMI  retains  all  rights  in its  Intellectual  Property  not
                  expressly granted to ENHANCE in Article 12.

         13.2     In   addition,   DMI  shall  have  the  right,   but  not  the
                  responsibility  or  obligation,  to market  Product(s) for the
                  Field  within the  Territory  ("Co-Marketing  Rights").  These
                  Co-Marketing  Rights  shall  include  the right to make,  have
                  made,  use, sell,  offer for sale,  commercialize,  import and
                  export  Product(s) to the extent  necessary for DMI to be able
                  to market Product(s) for the Field within the Territory.

         13.3     DMI shall have the right to assign its rights to Third Parties
                  with the approval of ENHANCE in all or part of the  Territory,
                  provided   the   assignee   agrees  to  assume  all  of  DMI's
                  obligations and responsibilities  under this Agreement in all,
                  or the assignee's part, of the Territory.


              Article 14. Licenses And Sublicenses Of Third Parties

         14.1     DMI  shall  have the  right to  license  its  rights  to Third
                  Parties in all or part of the  Territory  with the approval of
                  ENHANCE.

         14.2     ENHANCE shall have the right to sublicense its rights to Third
                  Parties in all or part of the  Territory  with the approval of
                  DMI.

         14.3     If the parties  desire that a single  licensee/sublicensee  be
                  responsible  for  the  development  and  commercialization  of
                  Product(s)  for the  Field in all or a part of the  Territory,
                  the parties will jointly select the licensee/sublicensee.  DMI
                  agrees to license its rights, and ENHANCE agrees to sublicense
                  its rights, to any such licensee/sublicensee as necessary.


                       Article 15. Third-Party Contractors

         15.1     The parties may  individually  or jointly  enter into  written
                  contracts with Third Parties to perform activities required of
                  them under the terms of this  Agreement or in  furtherance  of
                  the goals of this Agreement,  including,  without  limitation,
                  Third-Party manufacturers, consultants, clinical investigators
                  and contract research organizations.

         15.2     Any such  Third-Party  contractors must agree to adhere to all
                  applicable laws, regulatory  guidelines and requirements,  and
                  quality standards for the research, development,  manufacture,
                  Preclinical  Studies  and/or  Clinical  Trials it performs and
                  must agree to use only qualified personnel to perform the work
                  which is the subject of the Third-Party contract.


                                       22



         15.3     All  Third-Party  contractors  must also  agree to be bound by
                  confidentiality  and nonuse provisions which are substantially
                  the same as those contained in Article 16.

         15.4     All Third-Party  contractors  must further agree to assign any
                  Intellectual Property conceived, created, discovered, produced
                  or  developed  as a result  of the Third  Party's  performance
                  under the  contract  to the party  with whom the  contract  is
                  made.

         15.5     All Third-Party contracts for the manufacture and/or supply of
                  Product(s) or for the  performance of  Preclinical  Studies or
                  Clinical  Trials must be  approved in advance by the  Steering
                  Committee.

         15.6     Third-Party  contracts are distinguished  herein from licenses
                  and   sublicenses   because  no  payments   are  made  by  the
                  Third-Party  contractors to DMI and/or ENHANCE pursuant to the
                  terms of a Third-Party contract.



                           Article 16. Confidentiality

         16.1     Each  party  agrees  to treat  and  maintain  any of the other
                  party's  Proprietary  Information  which is in its possession,
                  which  comes  into  its  possession  during  the  term of this
                  Agreement,  or  which  is  conceived,   created,   discovered,
                  produced, developed or obtained by the other party as a result
                  of performance under this Agreement, in confidence, and agrees
                  not to disclose any such Proprietary Information to anyone and
                  to not use any such  Proprietary  Information,  except for the
                  purposes of performing its  obligations  under this Agreement.
                  Notwithstanding  the  foregoing,  each party may  disclose the
                  other  party's  Proprietary   Information  to  its  employees,
                  consultants,  agents,  and Third-Party  contractors,  or as is
                  deemed necessary for any purpose set forth in, or relating to,
                  this Agreement, provided that any recipients are bound by like
                  duties  of   confidentiality,   nondisclosure  and  nonuse  as
                  contained herein. Further, each party may disclose and use the
                  other party's Proprietary Information with the written consent
                  of the other party.

         16.2     As of  the  Effective  Date,  this  Agreement  supersedes  the
                  confidentiality  agreement  between the parties dated November
                  13, 2002, but only insofar as such  confidentiality  agreement
                  relates  to  the  subject  matter  of  this   Agreement.   All
                  Proprietary  Information  exchanged  between the parties under
                  such confidentiality  agreement relating to the subject matter
                  of this  Agreement  shall be  deemed  Proprietary  Information
                  hereunder and shall be subject to the terms of this Agreement.


                                       23



         16.3     Notwithstanding  the  foregoing,  each party may  disclose the
                  existence and content of this  Agreement and other  agreements
                  between  the  parties  to   advisors,   agents,   consultants,
                  investors, and Third-Party contactors who agree to be bound by
                  like duties of  confidentiality,  nondisclosure  and nonuse as
                  contained herein.

         16.4     Nothing  contained  herein shall in any way restrict or impair
                  the right of either party to use, disclose,  or otherwise deal
                  with the other party's Proprietary Information which the party
                  claiming waiver can demonstrate by written records:

                  (a)      is or becomes  generally  known to the public through
                           no fault of the party;

                  (b)      was  known to it prior to the time of  disclosure  by
                           the other party;

                  (c)      was independently developed by it;

                  (d)      was lawfully  obtained  without  restrictions  from a
                           Third   Party   who  has   authority   to  make  such
                           disclosure; or

                  (e)      which the party is required  to disclose  pursuant to
                           applicable   law  or  pursuant   to  a   requirement,
                           subpoena,  order or other request of a court,  agency
                           or  other  governmental  entity,  including  required
                           disclosures  to a  governmental  entity  or agency in
                           connection   with   seeking   any   governmental   or
                           regulatory  approval;  in such case,  the party shall
                           notify the other party prior to such disclosure so as
                           to give the other party an opportunity to protest the
                           disclosure.


              Article 17. Publicity, Publications And Presentations

         17.1     The  parties  agree  that  the  public   announcement  of  the
                  execution  of this  Agreement  shall be in the form of a press
                  release  to be  agreed  on by  the  parties  before  or on the
                  Effective Date and,  thereafter,  each party shall be entitled
                  to make or publish any public  statement  consistent  with the
                  contents thereof. Thereafter, the parties will jointly discuss
                  and  agree  on any  statement  to the  public  regarding  this
                  Agreement, the transactions  contemplated herein, or clinical,
                  regulatory  and  commercial   developments   relating  to  the
                  Product(s),  subject  in  each  case to  disclosure  otherwise
                  required by law or  regulation  as determined in good faith by
                  each party. When a party wishes to make a public statement, it
                  will  notify the other party and give the other party at least
                  three  (3)  business  days  to  review  and  comment  on  such
                  statement, and the parties will discuss and agree on the final
                  content of the  statement.  If a party is not legally  able to
                  give  notice as  required by the  previous  sentence,  it will
                  furnish the other party with a copy of its  disclosure as soon
                  as  practicable   after  the  making   thereof.   The  parties
                  acknowledge


                                       24



                  the importance of supporting  each other's efforts to publicly
                  disclose  results  and  significant   developments   regarding
                  Product(s).  The  principles  to be  observed  in such  public
                  disclosures will be accuracy, the confidentiality requirements
                  of Article 16, compliance with regulatory  agency  regulations
                  and  guidelines,  the advantage a competitor may gain from any
                  public   statements   under  this  Subsection  17.1,  and  the
                  standards and customs in the pharmaceutical  industry for such
                  disclosures by companies comparable to DMI and ENHANCE.

         17.2     DMI and ENHANCE each acknowledge the other party's interest in
                  publishing  certain  of  the  results  of the  work  performed
                  pursuant  to  the  terms  of  this  Agreement  and  in  making
                  presentations at scientific meetings to (i) obtain recognition
                  within the  scientific  community,  (ii)  advance the state of
                  scientific knowledge,  and (iii) promote the Product(s).  Both
                  parties  also  recognize  their  mutual  interest in obtaining
                  valid patent rights for any inventions  concerning or relating
                  to delay of  ejaculation  and/or  Product(s) and in protecting
                  the confidentiality of their Proprietary Information.

                  (a)      Consequently,  if either party  desires to publish or
                           present the results of the work performed pursuant to
                           the     terms     of     this     Agreement,      the
                           publishing/presenting   party   shall   provide   the
                           nonpublishing/nonpresenting  party  and the  Steering
                           Committee  with a draft  manuscript  of the  proposed
                           publication or presentation.

                  (b)      The   nonpublishing/nonpresenting   party   and   the
                           Steering  Committee  shall have thirty (30) days from
                           receipt of the draft manuscript to review it.

                  (c)      The publishing/presenting  party agrees to delete any
                           information         identified         by         the
                           nonpublishing/nonpresenting  party as its Proprietary
                           Information    upon    written    request    of   the
                           nonpublishing/nonpresenting party received within the
                           thirty-day review period.

                  (d)      The publishing/presenting party also agrees to delete
                           any information  identified by the Steering Committee
                           as Proprietary Information,  the deletion of which is
                           necessary  for  the   protection  of  the  commercial
                           interests of the parties, upon written request of the
                           Steering  Committee  received  within the  thirty-day
                           review period.

                  (e)      If the Steering  Committee  objects in writing within
                           the  thirty-day  review period to the  publication or
                           presentation   as   being   inconsistent   with   the
                           publication  strategy  established  by  the  Steering
                           Committee   pursuant   to  Section   9.1,   then  the
                           publishing/presenting    party   and   the   Steering
                           Committee   will  discuss  in  good  faith   possible
                           modifications  of,


                                       25



                           or delays in, the  publication or  presentation.  The
                           publishing/presenting  party  shall have the right to
                           proceed with the  publication or  presentation  if an
                           agreement  with  the  Steering  Committee  about  the
                           proposed  modifications  or delays  cannot be reached
                           within  thirty  days  after  receipt  of the  written
                           objection.

                  (f)      Finally,      in     the      event      that     the
                           nonpublishing/nonpresenting  party  or  the  Steering
                           Committee  determines  that the manuscript  describes
                           patentable         subject        matter,         the
                           nonpublishing/nonpresenting party and/or the Steering
                           Committee  shall so notify the  publishing/presenting
                           party in writing within the thirty-day review period.
                           Upon    receipt    of    this    notification,    the
                           publishing/presenting party will delay publication of
                           the manuscript or the presentation of the information
                           contained  in the  manuscript  for a period of ninety
                           (90) days  from the date of  receipt  of the  written
                           notice.

                  INCURRED BY THE OTHER PARTY OR ANY THIRD PARTY.


                    Article 19. Defense Of Third-Party Claims

         19.1     With  respect  to claims or suits by Third  Parties  resulting
                  from, or arising out of, the  performance  of this  Agreement,
                  the parties hereto agree as follows:

                  (a)      Each  party  shall  have  the  right to  control  the
                           defense or  settlement  of any claim or suit that may
                           be  brought  against  it  with  counsel  of  its  own
                           choosing and at its own expense.

                  (b)      Each party  agrees to inform the other  party as soon
                           as  practicable of any such claim or suit and to keep
                           the  other  party  informed  about  the claim or suit
                           until resolved.

                  (c)      Each party agrees to  cooperate  with the other party
                           to the extent  necessary  with  respect to  defending
                           against   any  such   claim  or  suit.   All  of  the
                           cooperating  party's  expenses  shall be paid for, or
                           reimbursed by, the other party.

                  (d)      Each party  agrees  that it will not settle any claim
                           or suit  brought  against it without the input of the
                           other party,  which input will be  considered in good
                           faith.

         19.2     Notwithstanding the foregoing, a party seeking indemnification
                  from  the  other  party  must   proceed  as  provided  in  the
                  indemnification provisions of Article 21.


          Article 20. Infringement Or Misappropriation By Third Parties

         20.1     Each party  will  inform  the other as soon as  possible  upon
                  learning of any infringement or  misappropriation by any Third
                  Party of any  Intellectual  Property  currently  or  hereafter
                  owned by DMI.


                                       27



         20.2     DMI shall have the first option to proceed  against such Third
                  Party.  ENHANCE agrees that it will permit the use of its name
                  in any litigation suit, will sign all necessary  papers,  will
                  take all  rightful  oaths,  and will do  whatever  else may be
                  necessary to assist DMI in proceeding against the Third Party.
                  All costs,  expenses and  disbursements of proceeding  against
                  such   Third   Party   shall  be   borne  by  DMI,   including
                  reimbursement  of expenses  incurred by ENHANCE as a result of
                  assisting DMI in proceeding against the Third Party. DMI shall
                  keep ENHANCE fully informed of all such proceedings. DMI shall
                  not settle any such  proceeding  without the input of ENHANCE,
                  which input will be  considered  in good  faith.  In the event
                  that DMI is successful in proceeding  against the Third Party,
                  all   monies    recovered   by   DMI   for   infringement   or
                  misappropriation  by way of settlement or order of court shall
                  be  treated as  follows.  If it has not  already  done so, DMI
                  shall  deduct  and  reimburse   ENHANCE  the  attorneys  fees,
                  disbursements  and costs expended by ENHANCE in the conduct of
                  proceeding against the Third Party. Next, DMI shall deduct and
                  retain the attorneys fees, disbursements and costs expended by
                  DMI in the conduct of proceeding  against the Third Party. Any
                  monies  remaining  after  such  deduction  shall be divided as
                  follows: 75% to DMI and 25% to ENHANCE.

         20.3     In the event  that DMI elects not to  proceed,  ENHANCE  shall
                  have the right to proceed against the Third Party.  DMI agrees
                  that it will  permit  the  use of its  name in any  litigation
                  suit, will sign all necessary  papers,  will take all rightful
                  oaths,  and will do whatever  else may be  necessary to assist
                  ENHANCE in  proceeding  against  the Third  Party.  All costs,
                  expenses and  disbursements  of proceeding  against such Third
                  Party shall be borne by ENHANCE,  including  reimbursement  of
                  expenses  incurred by DMI as a result of assisting  ENHANCE in
                  proceeding  against the Third  Party.  ENHANCE  shall keep DMI
                  fully  informed  of all such  proceedings.  ENHANCE  shall not
                  settle any such  proceeding  without  the input of DMI,  which
                  input  will be  considered  in good  faith.  In the event that
                  ENHANCE is successful  in proceeding  against the Third Party,
                  all  monies   recovered   by  ENHANCE  for   infringement   or
                  misappropriation  by way of settlement or order of court shall
                  be treated as follows.  If it has not already done so, ENHANCE
                  shall   deduct  and   reimburse   DMI  the   attorneys   fees,
                  disbursements  and costs  expended  by DMI in the  conduct  of
                  proceeding against the Third Party. Next, ENHANCE shall deduct
                  and  retain  the  attorneys  fees,   disbursements  and  costs
                  expended by ENHANCE in the conduct of  proceeding  against the
                  Third Party.  Any monies  remaining after such deduction shall
                  be divided as follows: 75% to ENHANCE and 25% to DMI.


                           Article 21.  Indemnification


                                       28



         21.1     ENHANCE  hereby agrees to indemnify,  defend and hold harmless
                  DMI,  its  officers,  directors,  employees,  consultants  and
                  agents  from  and  against  any and all  liabilities,  claims,
                  demands,  actions,  suits, damages, costs, expenses (including
                  reasonable   attorneys'  fees),  or  judgments   (collectively
                  "Damages")  arising out of,  based upon,  resulting  from,  or
                  presented or brought on account of, a material  breach of this
                  Agreement  by ENHANCE,  except to the extent that such Damages
                  arise out of,  are based  upon or result  from (i) a  material
                  breach  of the  Agreement  by DMI or (ii)  the  negligence  or
                  willful misconduct of DMI.

         21.2     DMI  hereby  agrees to  indemnify,  defend  and hold  harmless
                  ENHANCE, its officers, directors,  employees,  consultants and
                  agents,  from and against any  liabilities,  claims,  demands,
                  actions, suits, damages, costs, expenses (including reasonable
                  attorneys'  fees),  or  judgments   (collectively   "Damages")
                  arising out of, based upon,  resulting  from,  or presented or
                  brought on account of, a material  breach of this Agreement by
                  DMI,  except to the extent that such Damages arise out of, are
                  based  upon  or  result  from  (i) a  material  breach  of the
                  Agreement  by  ENHANCE  or  (ii)  the  negligence  or  willful
                  misconduct of ENHANCE.

         21.3     ENHANCE  hereby agrees to indemnify,  defend and hold harmless
                  DMI,  its  officers,  directors,  employees,  consultants  and
                  agents,  from and against any  liabilities,  claims,  demands,
                  suits, actions,  damages, costs, expense (including reasonable
                  attorneys'  fees),  or  judgments   (collectively   "Damages")
                  arising out of, based upon,  resulting  from,  or presented or
                  brought  on  account  of,  any  injuries,  losses  or  damages
                  sustained by any person or property in  consequence of any act
                  or omission of ENHANCE, except to the extent that such Damages
                  arise out of,  are based  upon or result  from (i) a  material
                  breach  of the  Agreement  by DMI or (ii)  the  negligence  or
                  willful misconduct of DMI.

         21.4     DMI  hereby  agrees to  indemnify,  defend  and hold  harmless
                  ENHANCE, its officers, directors,  employees,  consultants and
                  agents,  from and against any  liabilities,  claims,  demands,
                  suits, actions,  damages, costs, expense (including reasonable
                  attorneys'  fees),  or  judgments   (collectively   "Damages")
                  arising out of, based upon,  resulting  from,  or presented or
                  brought  on  account  of,  any  injuries,  losses  or  damages
                  sustained by any person or property in  consequence of any act
                  or  omission of DMI,  except to the extent  that such  Damages
                  arise out of,  are based  upon or result  from (i) a  material
                  breach of the  Agreement by ENHANCE or (ii) the  negligence or
                  willful misconduct of ENHANCE.

         21.5     A party entitled to indemnification under this Article 21 (the
                  "Indemnified   Party")   shall   promptly   notify  the  party
                  potentially   responsible   for  such   indemnification   (the
                  "Indemnifying  Party")  upon  becoming  aware of any  claim or
                  claims asserted or threatened  against such Indemnified  Party
                  which


                                       29



                  could  give  rise to a right  of  indemnification  under  this
                  Agreement;  provided,  however,  that the failure to give such
                  notice  shall  not  relieve  the  Indemnifying  Party  of  its
                  indemnity obligation hereunder, except to the extent that such
                  failure substantially prejudices its rights hereunder.

         21.6     The Indemnifying  Party shall have the right to defend, at its
                  sole  cost  and  expense,   such  claim  by  all   appropriate
                  proceedings,  which proceedings shall be prosecuted diligently
                  by the Indemnifying  Party to a final conclusion or settled at
                  the discretion of the Indemnifying Party;  provided,  however,
                  that the Indemnifying  Party may not enter into any compromise
                  or settlement  unless the Indemnified  Party consents thereto,
                  which consent shall not be unreasonably withheld,  conditioned
                  or delayed.

         21.7     The Indemnified Party may participate in, but not control, the
                  defense  or  settlement   of  any  claim   controlled  by  the
                  Indemnifying  Party pursuant to this Article 21 and shall bear
                  its own costs and expenses with respect to such participation;
                  provided, however, that the Indemnifying Party shall bear such
                  costs and expenses if counsel for the Indemnifying Party shall
                  have reasonably  determined that such counsel may not properly
                  represent  both the  Indemnifying  Party  and the  Indemnified
                  Party.

         21.8     If the  Indemnifying  Party  fails to notify  the  Indemnified
                  Party  within  twenty  (20) days after  receipt of notice of a
                  claim in accordance with Section 21.5 hereof that it elects to
                  defend the  Indemnified  Party pursuant to this Article 21, or
                  if the  Indemnifying  Party  elects to defend the  Indemnified
                  Party but fails to  prosecute  or settle the claim  diligently
                  and promptly,  then the Indemnified Party shall have the right
                  to defend,  at the sole cost and  expense of the  Indemnifying
                  Party,  the  claim  by  all  appropriate  proceedings,   which
                  proceedings shall be promptly and vigorously prosecuted by the
                  Indemnified   Party  to  a  final  conclusion  or  settlement;
                  provided,  however,  that in no event  shall the  Indemnifying
                  Party be required to indemnify the  Indemnified  Party for any
                  amount  paid  or  payable  by  the  Indemnified  Party  in the
                  settlement  of any such claim agreed to without the consent of
                  the   Indemnifying   Party,   which   consent   shall  not  be
                  unreasonably withheld, conditioned or delayed.


                              Article 22. Insurance

         22.1     DMI and ENHANCE will obtain and maintain (i) general liability
                  insurance  in  comprehensive  form in an  appropriate  amount,
                  which shall  cover no less than the  following  risks:  bodily
                  injury,  personal  injury,  liability,   property  damage  and
                  products  liability,  and (ii) such other  types of  insurance
                  considered  to be  reasonable  and prudent  given the types of
                  risks involved in research, development, pre-commercialization
                  and  commercialization  of pharmaceuticals,  and the liability
                  limits on any such insurance shall be reasonable for the risks
                  involved.  Each party shall obtain and maintain  such


                                       30



                  coverage with Third Party commercial  insurance carriers rated
                  A or  better.  Each  party  shall  name the other  party as an
                  additional insured on the  above-described  policies and shall
                  provide the other party with copies of the endorsement to such
                  insurance  policies  naming the other  party as an  additional
                  insured.  Each party shall  instruct  its  insurance  carriers
                  providing  such  coverage to notify the other party in writing
                  of any material change in coverage provided by such policies.


                        Article 23. Term And Termination

         23.1     Unless  terminated  sooner as provided  below,  this Agreement
                  will  continue in full force and effect until the later of (i)
                  such time after the First Commercial Sale when no Sales of any
                  Product(s)  for the  Field  have  been  made  anywhere  in the
                  Territory  for a period of one (1) year by either  party or by
                  any licensees, sublicensees and/or assignees of one or both of
                  the parties,  (ii) one (1) year after the  termination  of all
                  licenses and  sublicenses,  or (iii) fifty (50) years from the
                  Effective Date.

         23.2     The parties may at any time terminate this Agreement,  in part
                  or in its entirety, by mutual written agreement.

         23.3     In the event of a breach or  default  in respect of any of the
                  terms of this Agreement by either party, the other party shall
                  give notice in writing, specifying in detail the nature of the
                  breach or  default.  If the  alleged  breach or default is not
                  cured within sixty (60) days after receipt of this notice, the
                  party  giving  notice  shall  have the  right  to  immediately
                  terminate  this Agreement by giving a second written notice to
                  the breaching party.

         23.4     In  the  event  of   either   party   experiencing   financial
                  difficulties,  that party shall  immediately  notify the other
                  party to that  effect.  The party so  notified  shall have the
                  right to terminate this  Agreement  within thirty (30) days of
                  said notification.  If the party having the right to terminate
                  decides not to do so, then the parties agree to renegotiate in
                  good faith a reduction in the share of the Revenues to be paid
                  to the party experiencing financial difficulties if that party
                  is unable to fully perform its obligations  hereunder. A party
                  shall be considered as having financial difficulties by:

                           commencement of such a voluntary case;

                  (b)      that  party's  failing  to receive  dismissal  of any
                           involuntary case under any applicable bankruptcy code
                           or statute (wherein the other party is not a party to
                           the case) within sixty (60) days after  initiation of
                           such action or petition;


                                       31



                  (c)      that  party's  seeking  relief as a debtor  under any
                           applicable  law of any  jurisdiction  relating to the
                           liquidation  or  reorganization  of debtors or to the
                           modification   or   alteration   of  the   rights  of
                           creditors, or by consenting to or acquiescing in such
                           relief;

                  (d)      the  entry  of  an  order  by a  court  of  competent
                           jurisdiction  finding it to be bankrupt or insolvent,
                           or   ordering   or   approving    its    liquidation,
                           reorganization,  or any modification or alteration of
                           the rights of its creditors,  or assuming custody of,
                           or appointing a receiver or other  custodian for, all
                           or a substantial part of its property or assets; or

                  (e)      that party's making an assignment for the benefit of,
                           or entering into a composition  with,  its creditors,
                           or appointing or consenting to the  appointment  of a
                           receiver or other  custodian for all or a substantial
                           part of its property.

         23.5     Upon termination of this Agreement for any reason:

                  (a)      All rights and licenses granted to ENHANCE  hereunder
                           shall revert to DMI,  except that ENHANCE  shall have
                           the  right to sell any  Product(s)  in  inventory  as
                           provided in Subsection (b) of this Section 23.5.

                  (b)      ENHANCE  shall cease all  activities  with respect to
                           the  Product(s),  including  all making  (by  ENHANCE
                           and/or by Third Parties for ENHANCE), using, selling,
                           offering   for  sale,   marketing,   commercializing,
                           importing     and     exporting    of     Product(s).
                           Notwithstanding the foregoing, ENHANCE shall have the
                           right to sell any  Product(s) in inventory,  provided
                           ENHANCE  makes the payments  and reports  required by
                           Article 8.

                  (c)      If  requested  by  DMI,   ENHANCE  shall  (i)  remain
                           responsible  to supply the amounts of  Product(s)  it
                           was   obligated   to  supply  at  the  time  of  such
                           termination  for a reasonable  period of time, not to
                           exceed six (6) months  from the date of  termination,
                           to allow DMI to find an  alternate  source of supply,
                           (ii)  make  its   personnel   and   other   resources
                           reasonably  available  to  DMI  as  necessary  for  a
                           reasonable  period  of time,  not to  exceed  six (6)
                           months  from the date of  termination,  to  effect an
                           orderly  transition  of  responsibilities,  and (iii)
                           provide and assign to DMI all  clinical  data,  INDs,
                           Drug Approval Applications, Regulatory Approvals, and
                           all  other  regulatory   documentation  covering  the
                           Product(s)  that  ENHANCE may have  developed  in its
                           activities  under this  Agreement.  If termination of
                           the  Agreement   occurred  because  of  a  breach  by
                           ENHANCE,  then ENHANCE will be responsible for all of
                           the  costs  of  performing  these   obligations.   If
                           termination  of the Agreement  occurred  because of a


                                       32



                           breach by DMI, then DMI will be  responsible  for all
                           of  the  costs  of  performing   these   obligations.
                           Otherwise, the parties will share the costs.

                  (d)      ENHANCE's  sublicense(s)  of its rights  pursuant  to
                           Sections  14.2 and 14.3 above  (referred to herein as
                           "Article 14  Sublicense(s)")  shall be transferred to
                           DMI. The Article 14 Sublicense(s) will remain in full
                           force  and  effect  so  long  as  the  sublicensee(s)
                           perform(s)   the   obligations   of  the  Article  14
                           Sublicense(s),  and DMI shall  have all of the rights
                           and   benefits  of  the   Article  14   Sublicense(s)
                           (including  the right to receive 100% of all payments
                           due under the Article 14 Sublicense(s))  and shall be
                           responsible  for  performing  all of the  obligations
                           required of ENHANCE by the Article 14  Sublicense(s).
                           ENHANCE  will  execute  such   documents  as  may  be
                           requested  by DMI to attest to the transfer to DMI of
                           all of its Article 14 Sublicense(s).

         23.6     Upon  termination  of this  Agreement for any reason,  nothing
                  herein  shall be  construed  to release  either party from any
                  obligation  matured  prior  to  the  effective  date  of  such
                  termination,  and neither  party waives any rights it may have
                  to  remedies  arising  out of the  termination  or  breach  of
                  surviving obligations.

                  collaborative  effort  contemplated  hereby, the parties shall

                  Inc.

                  Officers of DMI  BioSciences,  Inc. and Enhance  Lifesciences,

                  Officers of DMI  BioSciences,  Inc. and Enhance  Lifesciences,
                  Inc.  that it wishes the matter to be referred to  non-binding
                  mediation.

         24.4     The  non-binding   mediation  will  proceed  as  follows.  The
                  controversy or claim shall be presented to a single  mediator.

                  Lifesciences,  Inc.  cannot agree on a single  mediator,  they
                  shall  each  appoint a  mediator  within  ten (10) days  after
                  receiving the  notification  specified in Subsection 24.3, and
                  these two mediators shall chose the single mediator within ten
                  (10) days after  being  appointed.  The single  mediator  will
                  conduct a hearing  within thirty (30) days after being chosen.

         24.5     If either party elects not to accept the non-binding  decision
                  of the  mediator,  that party shall be free to initiate  legal
                  proceedings in a court of competent jurisdiction in New York.

         24.6     This  Agreement  shall  be  governed  by,  and its  provisions

                  perform on its part any  provision  or part of this  Agreement

         25.3     For purposes of this Agreement,  "business day" means a day on
                  which the banks in the  United  States are  generally  open to
                  conduct their regular banking business.

         25.4     Should  any  part  or  provision  of  this  Agreement  be held
                  unenforceable or in conflict with the law, the validity of the
                  remaining  parts or  provisions  shall not be affected by such
                  holding.

         25.5     The failure of either  party to  enforce,  at any time and for
                  any period of time, a provision of this  Agreement is not, and
                  shall not be construed  to be, a waiver of any such  provision
                  or of the right of such party to subsequently enforce each and
                  every such provision.

         25.6     This   Agreement   constitutes   the  entire   agreement   and
                  understanding  between the parties with respect to the subject
                  matter   hereof,   and   supersedes  and  replaces  all  prior
                  negotiations,  understandings and agreements,  whether written
                  or oral,  including (i) the confidentiality  agreement between
                  the parties  dated  November 13, 2002, in part, as provided in
                  Subsection 16.2 hereof,  (ii) the Term Sheet executed November
                  29, 2002, and (iii) the Letter Of Intent effective January 29,
                  2003,  except that all payments due under the Letter Of Intent
                  will be paid within the times provided in the Letter of Intent
                  or within the times provided in this  Agreement,  whichever is
                  sooner.


                                       35



         25.7     All amendments and modifications of this Agreement shall be in
                  writing and executed by both parties.

         25.8     Each party will obtain any government approval required in its
                  country  of  domicile  to  enable  this  Agreement  to  become
                  effective,  or to enable any payment  hereunder to be made, or
                  any other  obligation  hereunder to be observed or  performed.
                  Each  party  will  keep the  other  informed  of  progress  in
                  obtaining any such  governmental  approval and will  cooperate
                  with the other party in any such efforts.

         25.9     This Agreement is made subject to any restrictions  concerning
                  the export of materials and technology  from the United States
                  which may be imposed  upon or related to either  party to this
                  Agreement  from time to time by the  Government  of the United
                  States. Neither party will export, directly or indirectly, any
                  Proprietary Information,  Intellectual Property, or Product(s)
                  or other materials  utilizing such technology to any countries
                  for which the United States  Government or any agency  thereof
                  at the time of  export  requires  an export  license  or other
                  governmental  approval,  without  first  obtaining the written
                  consent  to do so from the  Department  of  Commerce  or other
                  agency  of the  United  States  Government  when  required  by
                  applicable statute or regulation.

         25.10    This  Agreement  may be assigned by either party only with the
                  prior written  consent of the other party,  which consent will
                  not be unreasonably withheld, and provided the assignee agrees
                  to perform fully all of the  responsibilities  and obligations
                  of  the  assignor  hereunder.   Any  purported  assignment  in
                  contravention  of this Section  25.10 shall,  at the option of
                  the non-assigning party, be null and void and of no effect. No
                  assignment shall release either party from  responsibility for
                  performance of any accrued obligation of such party hereunder.

         25.11    This Agreement  shall be binding upon and inure to the benefit
                  of the parties,  their respective officers and directors,  and
                  the permitted assignees of either party.

         25.12    This Agreement may be executed in any number of  counterparts,
                  each of which  will be  deemed to be an  original,  and all of
                  which  together  shall  be  deemed  to be  one  and  the  same
                  instrument. Further, telefax signatures shall be binding.

         25.14    Nothing  contained herein shall be deemed to create an agency,
                  joint   venture,   amalgamation,    partnership   or   similar
                  relationship between DMI and ENHANCE.

         25.15    This Agreement does not confer,  and shall not be construed as
                  conferring,   on  either  party,  or  any  other  entity,  any
                  proprietary  right  or  license  in or to  the  other  party's
                  Proprietary  Information or Intellectual  Property,  except as
                  expressly provided in this Agreement.


                                       36



         25.16    Ambiguities,  if any, in this Agreement shall not be construed
                  against any party,  irrespective  of which party may be deemed
                  to have authored the ambiguous provision.

         25.17    The Article  headings are for convenience only and will not be
                  deemed to affect in any way the language of the  provisions to
                  which they refer.


         IN  WITNESS   HEREOF,   each  party   hereto   acknowledges   that  the
representative  named below has authority to execute this Agreement on behalf of
the  respective  party to form a legally  binding  contract  and has caused this
Agreement to be duly executed on its behalf.
