                  in  the  Clinical  Trial  to  the   regulatory   authority  in

         11.1     ENHANCE agrees to make the following payments to DMI:

                  (a)      Payment  of  all  costs  for  the  Research  Program,
                           including  the costs of all  Preclinical  Studies and
                           all of the costs of the  manufacture  or  purchase of

                           Product(s), including Indirect Costs, plus Reasonable
                           Overhead determined as set forth in Subsection (d) of
                           this Section 11.1.

                  (c)      Payment  of all  costs for Phase 2 Trials or Phase 2a
                           and  2b  Trials  of  Product(s),  including  Indirect

                           forth in Subsection (d) of this Section 11.1.

                  (d)      Reasonable Overhead,  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 Reasonable Overhead 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 Reasonable Overhead be
                           less  than  DMI's  actual  Overhead  plus 5% of total
                           costs. If the Reasonable Overhead  established by the
                           Steering  Committee  and paid to DMI as  provided  in
                           Subsection  (e) of this  Section  11.1  is less  than
                           DMI's actual  Overhead  plus 5% of total  costs,  the
                           deficiency  will  be  paid  to  DMI  as  provided  in
                           Subsection (e) of this Section 11.1.

                  (e)      Payments (a), (b) and (c) 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) and (c),
                           including the appropriate  Reasonable  Overhead,  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) after being requested by DMI.

                  (f)      DMI shall  keep  such  records,  books  and  accounts
                           showing  its  use  of  the   payments   specified  in
                           Subsections  (a), (b) and (c) of this Section 11.1 as
                           the Steering Committee may require.

         14.1     ENHANCE  shall pay DMI  royalties  on Net  Sales  made in each

                  for the Field in the Territory,  but only for those  countries

                  other party for the purpose of  verifying  the accuracy of the
                  quarterly  reports  required by Section 15.4 and Net Sales and
                  royalties computations.  Such examination shall be made during

                  from such books and records.  Each party shall fully

                  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 Section 15.4
                  and  calculations  of Net  Sales  and  royalties  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 Net
                           Sales  and  royalty   calculations   are  correct  or
                           incorrect,   the  specific  details   concerning  any
                           discrepancies,  and the corrected amount of Net Sales
                           and/or  royalties.   No  other  information  will  be
                           provided to the requesting party.

                  (b)      If the requesting party's independent accounting firm
                           determines  that royalties  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 royalties have been
                           underpaid,  the audited  party will pay the amount of
                           the additional royalties plus interest assessed at 2%
                           over the Prime Rate from the time(s)  the  payment(s)
                           was(were)  originally  due. If DMI is the  requesting
                           party and its independent  accounting firm determines
                           that Net Sales have  under-calculated  resulting in a
                           delay in the payment of a milestone  payment required
                           by  Article  12,  ENHANCE  will pay the amount of the
                           milestone  payment plus interest  assessed at 2% over
                           the  Prime  Rate  from  the  time  the   payment  was
                           originally   due.  The  payment  of  the   additional
                           royalties  and interest or of the  milestone  payment
                           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  royalties  payable by
                           the audited  party to the  requesting  party for such
                           period exceed 5% of the royalties actually paid, then
                           the audited  party will pay the  reasonable  fees and
                           expenses charged by such accounting firm.  Similarly,
                           if  an  audit   by  DMI   determines   that   ENHANCE
                           under-calculated Net Sales by 5% or more resulting in
                           a delay in the payment of a milestone  payment,  then
                           ENHANCE  will pay the  reasonable  fees and  expenses
                           charged by such accounting firm.


                                       17





         15.7     Each party will treat all financial  information  of the other
                  party  subject to review under this Article 15 as  Proprietary
                  Information  in  accordance  with  Article  21 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 21.

                                       18





         16.6     ENHANCE  will  assist  DMI in  every  proper  way  to  obtain,
                  maintain  and enforce  United  States and foreign  proprietary
                  rights  relating to any and all  Intellectual  Property now or
                  hereafter  owned by DMI which concerns or relates to treatment
                  of  dermatological  diseases and  conditions,  DMI 9742 and/or
                  Product(s). To that end, ENHANCE will:

                  (a)      Execute,   verify  and  deliver  such  documents  and
                           perform such other acts (including providing evidence
                           and  witnesses  within its control and appearing as a
                           witness)  as DMI may  reasonably  request  for use in
                           applying  for,  obtaining,  perfecting,   evidencing,

                           designee.

                  (c)      In the  event  DMI is unable  for any  reason,  after
                           reasonable  effort, to secure ENHANCE's  signature on
                           any document  needed in  connection  with the actions
                           specified   in  this  Article  16,   ENHANCE   hereby
                           irrevocably  designates and appoints DMI and its duly
                           authorized  officers  and  agents  as its  agent  and
                           attorney-in-fact,  to act for and on ENHANCE's behalf
                           to execute, verify and file any such documents and to
                           do all other  lawfully  permitted acts to further the
                           purposes of this Article 16 with the same legal force
                           and effect as if executed by ENHANCE.

         16.7     DMI will  take all  necessary  steps to  obtain  and  maintain
                  protection  for all  Intellectual  Property  now or  hereafter
                  owned by it, and DMI shall be responsible  for, and shall bear
                  all the costs of, obtaining and maintaining protection for its
                  Intellectual Property.

         16.8     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.

         16.9     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.

                  with the development and  commercialization  of Product(s) for
                  the Field within the  Territory  pursuant to the terms of this
                  Agreement.   The  licensed   Intellectual  Property  includes,

                  the   inventions   described   in  any  and  all  such  patent
                  applications and patents.

         17.2     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 18. Retention Of Rights By DMI

         18.1     DMI  retains  all  rights  in its  Intellectual  Property  not
                  expressly granted to ENHANCE in Article 17.

         18.2     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").

                  (a)      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

                  (b)      If DMI does market  Products for the Field within the
                           Territory, DMI agrees to pay ENHANCE royalties on Net

                                       20





                           (i)      Payments  of  royalties  shall  be due on or
                                    before  thirty  (30) days after the last day
                                    of each Calendar  Quarter in which there are
                                    Net Sales.

                           (ii)     The royalty rate for a  particular  Calendar
                                    Quarter will be based on the  cumulative Net
                                    Sales  that  have  been  made  by DMI of all
                                    Product(s) in the  Territory  from the First
                                    Commercial  Sale by DMI until the end of the
                                    Calendar  Quarter  for which  royalties  are
                                    being paid as shown in the following table:

- ------------------------------------------------- ------------------------------
AMOUNT OF CUMULATIVE NET SALES                    ROYALTY RATE

Net Sales over $500,000,000                       10% of Net Sales
- ------------------------------------------------- ------------------------------


                           (iii)    These  royalty  rates  will be reduced by an
                                    amount to be  negotiated,  but not to exceed
                                    25%,  if it  becomes  necessary  for  DMI to
                                    acquire or license the Intellectual Property
                                    of one or more Third  Parties in order to be
                                    able to market  Product(s)  for the Field in
                                    the Territory,  but only for those countries
                                    and those time periods for which acquisition
                                    or  license  of  Third  Party   Intellectual
                                    Property is necessary.

         18.3     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.

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

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

         19.3     If the parties desire that a single licensee/sublicensee shall

                  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 20.  Third-Party Contractors

         20.1     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.

         20.2     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,  Clinical  Trials  and/or  other work it
                  performs  and must agree to use only  qualified  personnel  to
                  perform  the work  which  is the  subject  of the  Third-Party
                  contract.

         20.3     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 21.

         20.4     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.

         20.5     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.

         20.6     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 the Third-Party contract.


                           Article 21. Confidentiality

         21.1     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


                                       22





                  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.

         21.2     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.

         21.3     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.

         21.4     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 22. Publicity, Publications And Presentations

         22.1     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


                                       23





                  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  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 21, compliance with regulatory  agency  regulations
                  and  guidelines,  the advantage a competitor may gain from any
                  public   statements   under  this  Subsection  22.1,  and  the
                  standards and customs in the pharmaceutical  industry for such
                  disclosures by companies comparable to DMI and ENHANCE.

         22.2     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 treatment of  dermatological  diseases and conditions,  DMI
                  9742 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


                                       24





                           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   3.1,   then  the
                           publishing/presenting    party   and   the   Steering
                           Committee   will  discuss  in  good  faith   possible
                           modifications  of, 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.

         24.1     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.


                                       26





         24.2     Notwithstanding the foregoing, a party seeking indemnification
                  from  the  other  party  must   proceed  as  provided  in  the
                  indemnification provisions of Article 26.


          Article 25. Infringement Or Misappropriation By Third Parties

         25.1     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.

         25.2     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.

         25.3     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,


                                       27





                  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 26. Indemnification

         26.1     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.

         26.2     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.

         26.3     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.

         26.4     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


                                       28





                  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.

         26.5     A party entitled to indemnification under this Article 26 (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 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.

         26.6     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.

         26.7     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 26 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.

         26.8     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 26.5 hereof that it elects to
                  defend the  Indemnified  Party pursuant to this Article 26, 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 27. Insurance


                                       29





         27.1     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 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 28.  Term And Termination

         28.1     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 commercial
                  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 parties,  (ii) one (1) year after the  termination of all
                  licenses  and  sublicenses  pursuant  to Article  19, or (iii)
                  fifty (50) years from the Effective Date.

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

         28.3     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.

         28.4     In  the  event  of   either   party   experiencing   financial
                  difficulty,  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.  A party  shall be  considered  as  having
                  financial difficulties by:

                  (a)      that party's  commencement  of a voluntary case under
                           any applicable  bankruptcy code or statute, or by its
                           authorizing,   by   appropriate   proceedings,    the
                           commencement of such a voluntary case;


                                       30





                  (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;

                  (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 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,

         28.5     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 28.5.

                  (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
                           Articles 12-15.

                  (c)      If  requested  by DMI,  ENHANCE  shall  (i)  make its
                           personnel and other resources reasonably available to
                           DMI 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
                           (ii)  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


                                       31





                           Agreement  occurred  because of a 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  19.2 and 19.3 above  (referred to herein as
                           "Article 19  Sublicense(s)")  shall be transferred to
                           DMI. The Article 19 Sublicense(s) will remain in full
                           force  and  effect  so  long  as  the  sublicensee(s)
                           perform(s)   the   obligations   of  the  Article  19
                           Sublicense(s),  and DMI shall  have all of the rights
                           and benefits of the Article 19 Sublicenses (including
                           the right to receive  100% of all  payments due under
                           the Article 19 Sublicenses)  and shall be responsible
                           for  performing  all of the  obligations  required of
                           ENHANCE by the Article 19  Sublicenses.  ENHANCE will
                           execute such  documents as may be requested by DMI to
                           attest  to the  transfer  to DMI  of all  Article  19
                           Sublicenses and rights therein.

         28.6     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.

                  Officers of DMI  BioSciences,  Inc. and Enhance  Lifesciences,

                  deadlocked  shall  also be  referred  to the  Chief  Executive

                  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.

         29.4     The  non-binding   mediation  will  proceed  as  follows.  The

                  Inc.  within ten (10) days after  receiving  the  notification
                  specified in Subsection  29.3. The single mediator shall be an
                  individual with experience and qualifications  suitable to the
                  controversy  or  claim  in  dispute.  If the  Chief  Executive
                  Officers of DMI  BioSciences,  Inc. and Enhance  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  29.3,  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.  The
                  hearing will be held at a time and place agreed to between the
                  parties  and the  mediator  and will last no longer than eight
                  (8) hours.  At the hearing,  each party will each have no more
                  than  four  (4)  hours  to  present  evidence,  witnesses  and
                  arguments,  to  present a proposed  remedy,  and to answer the
                  questions  of the  mediator.  Copies  of all  documents  to be
                  relied on by a party shall be provided to the mediator and the
                  other  party at least  three (3)  business  days  prior to the
                  hearing.  The  mediator  will  notify  the  parties of his/her
                  non-binding  decision  no later than three (3)  business  days
                  after the hearing.

         29.5     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.

         29.6     This  Agreement  shall  be  governed  by,  and its  provisions
                  construed  and  enforced in  accordance  with,  the law of the
                  State  of New  York.  Both  parties  agree  to  submit  to the
                  jurisdiction of all New York courts, including federal courts,
                  and  to  waive  any  and  all  rights  under  the  law  of any
                  jurisdiction  to object on any basis to  jurisdiction or venue
                  within New York.

         30.2     No party to this  Agreement  shall be liable  for  failure  to
                  perform on its part any  provision  or part of this  Agreement
                  when  such  failure  is due to fire,  flood,  strike  or other
                  industrial  disturbance,  unavoidable accident,  war, embargo,
                  inability  to  obtain  materials,   transportation   controls,
                  governmental  actions,  or other causes  beyond the control of
                  such party,  but only for the period of delay  imposed by such
                  cause.

                  unenforceable or in conflict with the law, the validity of the
                  remaining  parts or  provisions  shall not be affected by such
                  holding.

         30.5     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.

         30.6     This   Agreement   constitutes   the  entire   agreement   and
                  understanding  between the parties with respect to the subject
                  matter   hereof,   and   supersedes  and  replaces  all  prior

                  hereof.

         30.7     All amendments and modifications of this Agreement shall be in

                  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.

         30.9     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.

                  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  30.10 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.

         30.11    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.

         30.12    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.

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

         30.15    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.

         30.16    Ambiguities,  if any, in this Agreement shall not be construed
                  against any party,  irrespective  of which party may be deemed
