         4.3 The Company shall pay to the Licensor and/or his representatives a
non-refundable semi-annual royalty in an amount equal to *** percent (***%) of

received in an arms-length transaction, based on sales of like quantity and

         4.8 No multiple royalties shall be payable because the use, lease or
sale of any Licensed Product or Licensed Process is, or shall be, covered by
more than one valid and unexpired claim contained in the Patent Rights. In

based upon only one of paragraphs 4.3 or 4.4 above (that is, royalties on direct
sales of a Licensed Product or Licensed Process by the Company or its Affiliates
shall be based only on paragraph 4.3, while royalties on sales of a Licensed
Product or Licensed Process by the Company's sublicensees shall be based only on

combination product containing one or more products or technologies that are
themselves not a Licensed Product, the Net Sales for such combination product
shall be calculated by multiplying the sales price of such combination product

(or, if sold to an Affiliate, the Fair Market Value of the Licensed Product) and
B is the total invoice price of the other products or technologies (or, if
purchased from an Affiliate, the Fair Market Value of the other products or
technologies). In the case of a combination product which includes one or more
Licensed Products, the Net Sales for such combination product upon which the
royalty due to the Licensor is based shall not be less than the normal aggregate
Net Sales for such Licensed Product.

required, by order or judgement of any court to obtain in any jurisdiction any
license from a third party in order to make, use or sell any Licensed Product or
Licensed Process, then up to *** percent (***%) of the royalties payable
hereunder with respect to such Licensed Product or Licensed Process in such
jurisdiction may be deducted from royalties otherwise payable to the Licensor
hereunder, provided that in no event shall the aggregate royalties payable to
the Licensor in any semi-annual period in such jurisdiction be reduced by more
than *** percent (***%) as a result of any such deduction, and provided further
that any excess deduction remaining as a result of such limitation may be
carried forward to subsequent periods.

supporting data shall be open up to twice per year upon reasonable notice to the
Company, for three (3) years following the end of the calendar year to which
they pertain, for inspection by an auditor selected by the Licensor, except one

Company's royalty statement or compliance in other respects with this License
Agreement. If an inspection shows an under reporting or underpayment in excess

for any twelve (12) month period, then the Company shall reimburse the Licensor
for the cost of the inspection at the time the Company pays the unreported

due.

60-day period, if the Company shall not have paid all such royalties due and
payable, the rights, privileges and license granted hereunder shall, at the
option of the Licensor, immediately terminate.

         7.3 Upon any material breach or default of this License Agreement by
the Company, other than as set forth in Paragraphs 7.1 and 7.2 hereinabove, the
Licensor shall have the right to terminate this Agreement and the rights,
privileges and license granted hereunder upon giving sixty (60) days notice to
the Company. Such grounds for termination include, but shall not be limited to,
the Licensor's reasonable determination that the Company is not using its
reasonable best efforts to develop the Ketamine Technology and keep Licensed
Products or Licensed Processes reasonably available to the public after
commercial use commences. Such termination shall become effective immediately
unless the Company shall have cured any such breach or default prior to the
expiration of the sixty (60) day period referred to above.

proceeding for the purpose of obtaining or permitting either party to obtain
judicial resolution of such issues, unless an order staying the arbitration
proceeding shall be entered by a court of competent jurisdiction. Neither party
shall raise any issue concerning the validity, enforceability, or infringement
of any patent contained in the Patent Rights licensed hereunder, in any

                   ARTICLE 9 - INFRINGEMENT AND OTHER ACTIONS

         9.1 The Company and the Licensor shall promptly provide written notice,
to the other party, of any alleged infringement by a third party of the Patent
Rights and provide such other party with any available evidence of such
infringement.

         9.2 During the term of this Agreement, the Company shall have the
right, but not the obligation, to prosecute and/or defend, at its own expense
and utilizing counsel of its choice, any infringement of, and/or challenge to,
the Patent Rights. In furtherance of such right, the Licensor hereby agrees that
the Company may join the Licensor as a party in any such suit, without expense
to the Licensor. No settlement, consent judgment or other voluntary final
disposition of any such suit which would adversely affect the rights of the
Licensor may be entered into without the consent of the Licensor, which consent
shall not be unreasonably withheld. The Company shall indemnify and hold the
Licensor harmless against any costs, expenses or liability that may be found or
assessed against the Licensor in any such suit other than resulting from the
Licensor's gross negligence, recklessness or wilful misconduct.

         9.3 In the event that a claim or suit is asserted or brought against
the Company alleging that the manufacture or sale of any Licensed Product by the
Company, an Affiliate of the Company, or any sublicensee, or the use of such
Licensed Product by any customer of any of the foregoing, infringes proprietary
rights of a third party, the Company shall give written notice thereof to the
Licensor. The Company may, in its sole discretion, modify such Licensed Product
to avoid such infringement and/or may settle on terms that it deems advisable in
its sole discretion, subject to paragraph 9.2. Otherwise, the Company shall have
the right, but not the obligation, to defend any such claim or suit. In the
event the Company elects not to defend such suit, the Licensor shall have the
right, but not the obligation to do so at its sole expense.

         9.4 Any recovery of damages by the Company, in any such suit, shall be
applied first in satisfaction of any unreimbursed expenses and legal fees of the
Company relating to the suit and then to the Licensor for any royalties credited
in accordance with paragraph 9.4. The balance remaining from any such recovery
shall be treated as royalties received by the Company from sublicensees and
shared by the Licensor and the Company *** percent (***%) to the Company and ***
percent (***%) to the Licensor.

         9.5 The Company may credit up to fifty percent (50%) of any reasonable
litigation costs incurred by the Company in any country pursuant to this Article
9 and up to 50% of all amounts paid in judgement or settlement of litigation
within this Article 9 scope of against royalties thereafter payable to the
Licensor hereunder for such country and apply the same toward one-half of its
actual, reasonable out-of-pocket litigation costs. If one-half of such
litigation costs in such country exceeds 50% of royalties payable to the
Licensor in any year in which such costs are incurred than the amount of such
costs, expenses and amounts paid in judgement or settlement, in excess of such
50% of the royalties payable shall be carried over and credited against royalty
payments in future years for such country.

         9.6 If within ninety (90) days from receipt of notice by the Company of
any alleged infringement, the Company shall have been unsuccessful in persuading
the alleged infringer to desist, or shall not have brought and shall not be
diligently prosecuting an infringement action, or if the Company shall notify
the Licensor, at any time prior thereto, of its intention not to bring suit
against the alleged infringer, then, and in those events only, the Licensor
shall have the right, but not the obligation, to prosecute, at its own expense
and utilizing counsel of its choice, any infringement of the Patent Rights, and
the Licensor may, for such purposes, join the Company as a party plaintiff. The
total cost of any such infringement action commenced solely by the Licensor
shall be borne by the Licensor and the Licensor shall keep any recovery or
damages for infringement or otherwise derived therefrom and such shall not be
applicable to any royalty obligation of the Company.

         9.7 In any suit to enforce and/or defend the Patent Rights pursuant to
this License Agreement, the party not in control of such suit shall, at the
request and expense of the controlling party, cooperate in all respects and, to
the extent possible, have its employees testify when requested and make
available relevant records, papers, information, samples, specimens, and the
like.

         10.1 Other than as set forth in Article 2 hereof, the Licensor, by this
License Agreement, makes no representations or warranties as to the validity
and/or breadth of the inventions contained in the Patent Rights and the Company
so acknowledges. Other than as set forth in Article 2, the Licensor, by this
License Agreement makes no representations or warranties as to patents now held
or which will be held by others in the field of the Licensed Products and/or
Licensed Processes for a particular purpose.

         10.2 EXCEPT AS MAY BE EXPRESSLY PROVIDED HEREIN, THE LICENSOR DOES NOT
MAKE, AND EXPRESSLY DISCLAIMS ANY WARRANTIES, EITHER EXPRESS OR IMPLIED, ORAL OR
WRITTEN, AS TO MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

         10.3 The Company agrees to defend, indemnify and hold the Licensor
harmless from and against all liability, demands, damages, including without
limitation, expenses or losses including death, personal injury, illness or
property damage (each a "Claim") arising directly or indirectly: (a) out of use
by the Company or its transferees of inventions licensed or information
furnished under this License Agreement or (b) out of any use, sale or other
disposition by the Company or its transferees of Patent Rights, Licensed
Products or Licensed Processes, except to the extent, in each such case, that
such Claim results from or arises out of the Licensor's gross negligence,
recklessness or wilful misconduct. The Company agrees that any sublicense
agreement it enters relative to the Licensed Products and/or Licensed Processes
shall contain a covenant by such sublicensee providing for the indemnification
of the Licensor as provided in this Article.

         10.4 (a) The Company shall obtain and carry in full force and effect
commercial, general liability insurance, at such time when the Company has
developed Licensed Products for sale, which shall protect the Company and the
Licensor with respect to events covered by paragraph 10.3 above. Such insurance
shall be written by a reputable insurance company, shall list the Licensor as an
additional named insured thereunder, shall be endorsed to include product
liability coverage and shall require thirty (30) days written notice to be given
to the Licensor prior to any cancellation or material change thereof. The limits
of such insurance shall not be less than *** dollars ($***) per occurrence with
an aggregate of *** dollars ($***) for personal injury or death, and *** dollars
($***) per occurrence with an aggregate of *** dollars ($***) for property
damage. The Company shall provide the Licensor with Certificates of Insurance
evidencing the same.

         (b) Notwithstanding the foregoing, if the requirements of this
paragraph 10.4 are not consistent with general industry norms or good business
practices at the time, the Licensor agrees to negotiate in good faith to modify
this paragraph 10.4; provided, however, that if the Company, using good-faith
reasonable efforts, cannot obtain the insurance required by this paragraph 10.4
at rates that are prudent given the Company's financial position as determined
by the Board of Directors of the Company at the time such insurance is required
then the Licensor agrees to waive the requirements of this paragraph 10.4 until
a determination by the Board of Directors of the Company that the Company's
financial position permits it to obtain the insurance required by this paragraph
10.4.

any right to the Company or its Affiliates to use in advertising, publicity, or
other promotional activities any name, trade name, trademark, or other
designation of the Licensor or any of its units (including contraction,
abbreviation or simulation of any of the foregoing) without the prior, written
consent of the Licensor; provided, however, that the Licensor acknowledges and
agrees that the Company may use the name of the Licensor in various documents
used by the Company for capital raising and financing without such prior written
consent where the use of such names may be required by law. The Company agrees
to promptly provide the Licensor with a copy of any documents used by the

liability upon one party for the act or failure to act of the other party.

         13.3 In the event that the Licensor desires to publish or disclose, by
written, oral or other presentation, Know-how, Patent Rights, or any material

or registered mail (return receipt requested) of its intention at least sixty

sixty (60) days before any written or other publication or disclosure. The
Licensor shall include with such notice a description of any proposed oral
presentation or, in any proposed written or other disclosure, a current draft of

no later than thirty (30) days following the receipt of such notice, delay such
presentation, publication or disclosure in order to enable the Company to file,
or have filed on their behalf, a patent application, copyright or other
appropriate form of intellectual property protection related to the information
to be disclosed or request that the Licensor does so. Upon receipt of such
request to delay such presentation, publication or disclosure, the Licensor
shall arrange for a delay of such presentation, publication or disclosure until
the earlier to occur of (a) to ninety (90) days and (b) such time as the Company
or the Licensor has filed, or has had filed on its behalf, such patent
application, copyright or other appropriate form of intellectual property
protection in form and in substance reasonably satisfactory to the Company and
the Licensor. If the Licensor does not receive any such request from the Company

such material for presentation, publication or other form of disclosure.

                            CONFIDENTIALITY AGREEMENT

         THIS IS A CONFIDENTIALITY AGREEMENT (the "Agreement"), dated as of
August 24, 2000 (the "Effective Date"), among West Pharmaceutical Services,
Inc., a Pennsylvania corporation, ("West") with offices at 101 Gordon Drive,
Lionville, PA, 19341, and its wholly owned subsidiaries West Pharmaceutical
Services Drug Delivery & Clinical Research Centre Ltd., a corporation organized
under the laws of England and Wales, ("West/Nottingham") with offices at Albert
Einstein Centre, Highfields Science Park, Nottingham, NG7 2TN, United Kingdom,
and West Pharmaceutical Services Lakewood, Inc., a Delaware corporation with
offices at 1200 Paco Way, Lakewood, New Jersey 08701 ("West/Lakewood");
Paramount Capital Investments, LLC, a New York limited liability corporation,
("Paramount") with offices at 787 Seventh Avenue, New York, New York 10019, and
Innovative Drug Delivery Systems, Inc., a Delaware corporation, ("IDDS") with
offices at 787 Seventh Avenue, New York, New York 10019. Each Party hereto may
be referred to herein as a "Party" or collectively as "Parties."

                                   Background

         West (directly and through its subsidiaries) is engaged in, among other
things, the research and development of novel means of delivering pharmaceutical
compounds using its patented and proprietary drug-delivery technology. IDDS
desires to conduct and fund further research and development activities with
respect to West's technology with a view toward commercialization of certain
identified products for the treatment of pain in humans and animals (the
"Projects"). To this end IDDS, West and West/Nottingham have entered into a
License Agreement (the "License Agreement") dated as of the Effective Date, and
the Parties intend to enter into other agreements in the future relating to the
Projects.

         In connection with these agreements and the activities conducted under
them, it will be necessary for the parties to disclose to the others certain
confidential and proprietary information. The parties wish to enter into this
Agreement to govern the treatment of Confidential Information (as defined
herein) relating to the Projects.

                                    Agreement

         Accordingly, intending to be legally bound, the Parties agree as
follows:

 1.  As used in this Agreement, the term "Confidential Information" means
     information that any Party desires to maintain as confidential or secret,
     which is supplied or provided to any other Party, including without
     limitation scientific, clinical, regulatory, marketing, financial and
     commercial information, data or results, whether communicated in writing or
     by other means (including orally or by visual observation of a Party's
     facilities or processes, if confirmed in writing within 30 days).
     Confidential Information shall include without limitation any confidential
     portions of Background IP and Program IP (as such terms are defined in the
     License Agreement).

<PAGE>

 2.  Each Party will keep all Confidential Information confidential and use
     Confidential Information only for the purposes of the Projects and not
     for the benefit of any third party. Without the prior written consent
     of the disclosing Party, no Party will analyze, have analyzed or
     otherwise attempt to determine the composition or structure of any
     samples, nor disclose any Confidential Information to any third party
     other than its directors, officers and employees who need to know the
     Confidential Information for the purpose stated above; provided, that a
     receiving Party may disclose Confidential Information to third parties
     where (a) it is necessary and appropriate to further the purposes of
     the Projects and the development, commercialization and sale of
     products to the benefit of the disclosing Party, and (b) before such
     disclosure such third party enters into a written agreement which
     provides that such Confidential Information shall be held confidential
     and not disclosed or used for any purpose other than as set forth
     herein, such written agreement to contain terms and conditions no less
     stringent than those of this Agreement.

 3.  All written disclosures of Confidential Information considered
     confidential by the disclosing Party shall bear the notation
     "Confidential." All non-written disclosures of Confidential Information
     shall be confirmed by the disclosing Party in writing as being
     confidential within thirty (30) days following the non-written
     disclosure. The written confirmation shall identify the particular
     Confidential Information, state that it is considered confidential, and
     shall be addressed to the persons who received such non-written
     disclosures.

 4.  Each person who receives Confidential Information shall be informed that
     the Confidential Information is considered confidential and shall have
     agreed to be bound by the terms and conditions of this Agreement. Each
     Party shall ensure that Confidential Information is not used or
     disclosed except as permitted by this Agreement and shall be
     responsible for any breach of this Agreement by its directors, officers
     or employees.

 5.  The receiving Party shall take all reasonable steps, including, but not
     limited to, those steps taken to protect its own information, data or
     other tangible or intangible property that it regards as proprietary or
     confidential, to insure that the Confidential Information is not
     disclosed or duplicated for the use of any third party. The receiving
     Party shall also take all reasonable steps to prevent its employees, or
     any others having access to the Confidential Information, from
     disclosing or making unauthorized use of any Confidential Information,
     or from committing any acts or omissions that may result in a violation
     of this Agreement. The receiving Party shall indemnify the disclosing
     Party for any breach of this Agreement by its employees or the
     employees of its affiliates or sublicensees.

 6.  All Confidential Information shall remain the property of the disclosing
     Party, except for analysis, studies or other documents prepared by or
     for the receiving Party. Upon the written request of the disclosing
     Party (a) all tangible Confidential Information (including all copies
     thereof), except analyses, studies and other documents prepared by or
     for the benefit of the receiving Party, shall be promptly returned to
     the disclosing Party, and (b) all analyses, studies and other documents
     prepared by or for the benefit of the receiving Party (including all
     copies thereof) which are within the definition of Confidential
     Information shall be destroyed; provided, however, that the receiving
     Party may retain one copy of such Confidential Information for its
     records to ensure compliance hereunder.

                                       -2-

 7.  The obligations of confidentiality and non-use set forth in this Agreement
     shall not apply to any portion of the Confidential Information which:

     7.1. is or becomes available to the general public other than through the
          act or default of any Party or its agents;

     7.2. is obtained by a Party from a third party who (i) is rightfully in
          possession of the Confidential Information and (ii) does not violate
          any obligation of confidentiality or non-use by disclosing such
          Confidential Information;

     7.3. is in the receiving Party's possession prior to disclosure by the
          disclosing Party;

     7.4. is independently developed by a Party without use of or access to
          any other Party's Confidential Information; or

     7.5. is disclosed by a Party pursuant to a requirement of law, provided
          that such receiving Party has complied with the provisions of
          paragraph 8 below.

 8.  If a Party is requested or required by any legal process (such as
     deposition, interrogatories, requests for information, documents or
     admissions, subpoenas, or the like) to disclose any other Party's
     Confidential Information, the receiving Party will immediately notify the
     disclosing Party. The disclosing Party may seek an appropriate protective
     order and/or waive the receiving Party's obligation to comply with this
     Agreement. The receiving Party will fully cooperate with all efforts to
     obtain any such order or other remedy. If no protective order is obtained
     and the recipient has not received a waiver hereunder before one (1)
     business day prior to the time the recipient must disclose Confidential
     Information or else stand liable for contempt or suffer other sanction or
     penalty, the receiving Party may disclose to the minimum extent legally
     required the requested Confidential Information; the receiving Party will
     use its best efforts to have such disclosed Confidential Information
     treated as confidential.

 9.  Except with the written consent of the other Party, other than as permitted
     by paragraph 2 above neither Party will disclose to any third party (a)
     that Confidential Information has been made available or that discussions
     or negotiations may be taking place among the Parties with respect to the
     Projects, or (b) the terms, conditions, status or other aspects of any such
     negotiations, whether pending or concluded, among the Parties.

 10. Nothing herein shall be construed as giving any Party any right, title or
     interest in or ownership of any other Party's Confidential Information.
     With respect to any Confidential Information which is or becomes public
     information or is now or hereafter becomes covered by any patent, each
     Party's rights with respect thereto shall be subject to all rights of the
     patent owner and/or licensee.

 1l. Specific information disclosed as part of Confidential Information shall
     not be considered available to the general public or in the prior
     possession of recipient merely because it is embraced by more general
     information available to the general public or in the prior possession of
     any Party.

                                      -3-
<PAGE>

 12. Publication. In the event a Party chooses to publish any data relating to
     the technology disclosed hereunder (including without limitation the
     submission of such proposed publication to a journal, editor, selection or
     review committee or other person for a conference, symposium or other
     public meeting, or other third person), the publishing Party shall, at
     least four weeks in advance of any such publication, submit to the other
     Parties for review the text of any such proposed oral or written
     publication, including any abstract. The other Party may request in writing
     further delay of the proposed publication for up to an additional three
     months for purposes of allowing either Party to complete development
     necessary for filing a patent application and to file such a patent
     application. The terms of this Section shall not supersede the obligations
     of confidentiality set forth in this Agreement.

 13. Publicity. Neither West, West/Nottingham or West/Lakewood, on the one hand,
     nor Paramount or IDDS, on the other hand, shall issue any press release or
     other public statement, or any communication or response to a third Party,
     whether oral or written, disclosing the existence of this Agreement or any
     other agreement or information or activity relating to the activities among
     the Parties without the prior written consent of the other Party, which
     shall not be unreasonably withheld or delayed; provided, however, that no
     Party will be prevented from complying with any duty of disclosure it may
     have pursuant to law or governmental regulation, in which case, the
     disclosing Party shall provide the other Party reasonable prior written
     notice of such required disclosure.

 14. Use of Names. Neither West, West/Nottingham or West/Lakewood, on the one
     hand, nor Paramount or IDDS, on the other hand, will, without the prior
     written consent of the other Party, use the name or any trademark or trade
     name owned by the other Party, or owned by an affiliate of the other Party,
     in any publication, publicity, advertising or otherwise, except where
     required by law.

 15. The Parties recognize and acknowledge the competitive value and
     confidential nature of the other's Confidential Information and the
     irreparable damage that could result if Confidential Information is
     disclosed in violation of this Agreement. Each Party may institute
     appropriate proceedings to enforce its rights hereunder. The Parties
     acknowledge and agree that money damages would not be a sufficient remedy
     for any violation of this Agreement and, accordingly, either Party shall be
     entitled, in addition to any monetary damages, to specific performance and
     injunctive relief as remedies for any violation of this Agreement. These
     remedies shall not be exclusive but shall be in addition to all other
     remedies available at law or in equity.

 16. This Agreement constitutes the entire agreement among the Parties and
     supersedes and replaces all prior discussions, agreements and rights
     relating to the subject matter hereof The Parties agree that all
     Confidential Information disclosed between the Parties under the
     Confidentiality Agreement between West and Paramount dated August 31, 1999
     shall be considered Confidential Information covered by the terms of this
     Agreement.

 17. This Agreement may be amended only by a written instrument signed by the
     Parties.

 18. This Agreement may not be assigned by any Party without the prior written
     consent of the other Parties, provided however, that either Party may,
     without such consent, assign this Agreement and its rights and obligations
     hereunder to its Affiliates or in connection with the transfer or sale of
     all or substantially all of its business, or in the event of its merger or
     consolidation or change in control or similar transaction. Any purported
     assignment in violation of the preceding sentence: shall be void. Any
     permitted assignee shall assume all obligations of its assignor under this
     Agreement.

 19. This Agreement, and, any interpretation, dispute or controversy arising out
     of this Agreement, shall be governed by and construed in accordance with
     the laws of the Commonwealth of Pennsylvania, U.S.A., without regard to the
     conflicts of laws principles thereof.

 20. Any waiver by any Party of any provision of this Agreement shall not be
     construed or deemed to be a waiver of any other provision of this Agreement
     of a waiver of any subsequent breach of the same provision.

 21. This Agreement has been executed by each Party's authorized signatory.

 22. This Agreement shall be binding upon and enforceable by the Parties and
their successors and permitted assigns until the date five (5) years after the
