8     CONFIDENTIALITY

      8.1   Confidentiality:

            8.1.1   The Parties agree that it may be necessary pursuant to this
                    Agreement, from time to time, to disclose to each other
                    confidential and proprietary information, including without
                    limitation, inventions, trade secrets, specifications,
                    designs, data, know-how and other proprietary information,
                    processes, services and business of the disclosing Party.

                    The foregoing together with the terms of this Agreement
                    shall be referred to collectively as "Additional
                    Confidential Information".

                    The Parties also agree that it may have been necessary to
                    disclose to each other Confidential Information (as defined
                    in the JDOA) pursuant to the DOV Bermuda Agreements.

                    Together Additional Confidential Information and
                    Confidential Information shall be referred to collectively
                    as "Proprietary Information".

            8.1.2   Save as otherwise specifically provided herein, and subject
                    to Clause 8.2 and 8.3, each Party shall disclose Proprietary
                    Information of another Party only to those employees,
                    representatives and agents requiring knowledge thereof in
                    connection with fulfilling the Party's obligations under
                    this Agreement, and not to any other third party.

                    Each Party further agrees to inform all such employees,
                    representatives and agents of the terms and provisions of
                    this Agreement relating to Proprietary Information and their
                    duties hereunder and to obtain their agreement hereto as a
                    condition of receiving Proprietary Information.

                    Each Party shall exercise the same standard of care as it
                    would itself exercise in relation to its own confidential
                    information (but in no event less than a reasonable standard
                    of care) to protect and


                                       17


                    preserve the proprietary and confidential nature of the
                    Proprietary Information disclosed to it by another Party.

                    Each Party shall promptly, upon request of another Party,
                    return all documents and any copies thereof containing
                    Proprietary Information belonging to, or disclosed by, such
                    Party, save that it may retain one copy of the same solely
                    for the purposes of ensuring compliance with this Clause 8.

            8.1.3   Any breach of this Clause 8 by any person informed by one of
                    the Parties is considered a breach by the Party itself.

            8.1.4   Proprietary Information shall be deemed not to include:

                    (1)   information which is in the public domain;

                    (2)   information which is made public through no breach of
                          this Agreement;

                    (3)   information which is independently developed by a
                          Party, as evidenced by such Party's records;

                    (4)   information that becomes available to a receiving
                          Party on a non-confidential basis, whether directly or
                          indirectly, from a source other than another Party,
                          which source did not acquire this information on a
                          confidential basis.

            8.1.5   The provisions relating to confidentiality in this Clause 8
                    shall remain in effect during the term of this Agreement,
                    and for a period of 10 years following the Effective Date of
                    this Agreement.

            8.1.6   The Parties agree that the obligations of this Clause 8 are
                    necessary and reasonable in order to protect the Parties'
                    respective businesses, and each Party agrees that monetary
                    damages may be inadequate to compensate a Party for any
                    breach by another Party of its covenants and agreements set
                    forth herein.

                    The Parties agree that any such violation or threatened
                    violation may cause irreparable injury to a Party and that,
                    in addition to any other remedies that may be available, in
                    law and equity or otherwise, each Party shall be entitled to
                    seek injunctive relief against the threatened breach of the
                    provisions of this Clause 8, or a continuation of any such
                    breach by another Party, specific performance and other
                    equitable relief to redress such breach together with
                    damages and reasonable counsel fees and expenses to enforce
                    its rights hereunder.


                                       18


      8.2   Announcements:

            Subject to Clause 8.3, no announcement or public statement
            concerning the existence, subject matter or any term of this
            Agreement shall be made by or on behalf of any Party without the
            prior written approval of the other Parties.

            The terms of any such announcement shall be agreed in good faith by
            the Parties.

      8.3   Required Disclosures:

            8.3.1   A Party (the "Disclosing Party") will be entitled to make an
                    announcement or public statement concerning the existence,
                    subject matter or any term of this Agreement, or to disclose
                    Proprietary Information that the Disclosing Party is
                    required to make or disclose pursuant to:

                    (1)   a valid order of a court or governmental authority; or

                    (2)   any other requirement of law or any securities or
                          stock exchange;

                    provided that if the Disclosing Party becomes legally
                    required to make such announcement, public statement or
                    disclosure hereunder, the Disclosing Party shall give the
                    other Parties prompt notice of such fact to enable the other
                    Parties to seek a protective order or other appropriate
                    remedy concerning any such announcement, public statement or
                    disclosure.

                    The Disclosing Party shall fully co-operate with the other
                    Parties in connection with that other Party's or Parties'
                    efforts to obtain any such order or other remedy, provided
                    that, other than as agreed above, the Disclosing Party shall
                    not have any obligation to co-operate in connection with
                    that other Party's or Parties efforts to obtain any such
                    order or other remedy in relation to required SEC filings.

                    If any such order or other remedy does not fully preclude
                    announcement, public statement or disclosure, the Disclosing
                    Party shall make such announcement, public statement or
                    disclosure only to the extent that the same is legally
                    required.

            8.3.2   Each of the Parties shall be entitled to provide a copy of
                    this Agreement (and any subsequent amendments hereto) and
                    the DOV

                    Bermuda Agreements to a potential third party purchaser in
                    connection with Clause 10.2.1(2); provided that the relevant
                    third party purchaser or assignee has entered into a
                    confidentiality agreement on terms no less protective than
                    the terms of this Clause 8.

9     WAIVER OF ACCRUED RIGHTS/MUTUAL RELEASES

      9.1   With effect from the Effective Date, each Party and each of its
            Affiliates ("Releasor"):

            9.1.1   waives any accrued rights that Releasor may have accrued
                    against the other Parties and each of its Affiliates,
                    officers, directors, representatives, agents and employees
                    and the assigns and successors in interest of any of the
                    foregoing entities ("Releasees"), whether known or unknown,
                    foreseen or unforeseen, fixed or contingent, of any nature
                    whatsoever from the beginning of time to the Effective Date
                    under the DOV Bermuda Agreements; and

            9.1.2   fully and finally releases and discharges the Releasees from
                    any and all manner of actions, claims, promises, debts, sums
                    of money, demands, obligations, in law or in equity,
                    directly or indirectly, whether known or unknown, foreseen
                    or unforeseen, fixed or contingent, of any nature whatsoever
                    that Releasor may have by reason of any act, omission,
                    matter, provision, cause or thing whatsoever from the
                    beginning of time to the Effective Date under the DOV
                    Bermuda Agreements.

      9.2   For the avoidance of doubt the provisions of this Clause 9 shall not
            in any way act as a waiver by any of the Parties in respect of any
            of the provisions set forth in this Agreement (including, for the
            avoidance of doubt, Clause 3.7.1).

      9.3   For the further avoidance of doubt, the Parties acknowledge and
            agree that the waiver set forth in Clause 9.1 shall supercede the
            waiver and release set forth in Clause 6 of the Amendment Agreement.

10    GENERAL

            (1)     may assign this Agreement in whole or in part and delegate
                    its duties hereunder to its Affiliate or Affiliates without
                    such consent; and

            (2)     may assign its rights and obligations to a successor

                    its assets relating to such Party's technology related to

subsidiaries or Affiliates (including, without limitation, those securities
currently held by Elan Pharmaceutical Investments Ltd. and Elan Pharmaceutical
Investments II, Ltd.) are hereby deleted in their entirety and are of no further
force and effect. The Parties hereby agree that other than as mentioned above
the transfer of such securities of DOV are thus no longer subject to contractual
restrictions on transfer of any kind. The Parties recognize that such securities
remain subject to restrictions imposed under applicable securities laws. DOV
will use commercially reasonable efforts to inform its transfer agent, and
cooperate with the holder of such securities to confirm with prospective third
party transferees from time to time, of the elimination of such restrictions
and, if the certificate representing such securities is legended to reflect a
contractual restriction that is no longer in effect, DOV shall, if requested by
the holder of such securities, shall reissue such securities without such
restrictive legend.

S-3 under the Securities Act, any Holder or Holders who collectively hold
Registrable Securities representing at least 10% of the Registered Securities
then outstanding, shall be permitted unlimited Demand Registrations hereunder on
Form S-3, or any similar short-form registration (a "Short-Form Registration"),
if available; provided that such Holder or Holders, as applicable, will be
entitled to request only one Short-Form Registration in any 12-month period."

subsection (ii) in its entirety and inserting the following in lieu thereof:

      value U.S. $1.00 per share (the "Special Stock"; the shares of Common

thereof:

Section 6 ("Certain Rights of EIS") of the Securities Purchase Agreement is
hereby amended by deleting such section in its entirety and inserting the
following in lieu thereof:

      "Section 6. Certain Rights.

            (a)(i) Company Board of Directors. EIS shall have the right to
      nominate and elect one member to the Company's board of directors in
      accordance with the terms of the Special Stock as set forth in the
      Company's Certificate of Incorporation, as the same may be amended from
      time to time provided that (1) such right shall not be exercised prior to
      January 22, 2005, (2) notice of such exercise with identification of EIS's
      nominee shall be given no earlier than July 22, 2004, (3) if exercised
      such election shall at DOV's request be deferred up to six months if
      composition of the DOV board of directors is then such that a board member
      additional to the EIS nominee would be required for the board to be
      comprised of a majority of independent directors and (4) EIS's right to
      nominate and elect a board member shall not be transferred to other than
      an affiliate of EIS. For avoidance of doubt, no prohibition on transfer of
      the right to nominate and elect one member to the Company's board of
      directors shall prohibit or in any way restrict the transfer of securities
      of the Company.

            (a)(ii) Observer Rights. At any time EIS or an affiliate does not
      have a designee sitting on the Company's board of directors pursuant to
      the rights granted under the Company's Certificate of Incorporation (as
      qualified by Section 6(a)(i) above), EIS or an affiliate, if it then holds
      a majority of the issued and outstanding shares of Special Stock and at
      least ten percent (10%) of the capital stock of the Company, shall be
      entitled to appoint an observer to the Company's board of directors (such
      observer, the "Special Stock Representative"). The Special Stock
      Representative shall be entitled to receive the same notice of any
      meetings of the Company's board of directors as each member of the
      Company's board of directors shall receive, attend meetings of the
      Company's board of directors as an observer and shall be provided all
      information otherwise made available to the members of the Company's board
      of directors; provided that, with regard to the Special Stock
      Representative's status as an observer, (1) the Company may exclude the
      Special Stock Representative from access to any material or board meeting
      or any portion thereof, if the Company believes upon the advice of counsel
      that such exclusion is reasonably necessary to preserve the attorney
      client privilege; (2) the Special Stock Representative shall not be
      permitted to vote at any Company board meetings or be counted for purposes
      of determining whether there is a sufficient quorum for the board to
      conduct its business; and (3) the Special Stock Representative shall agree
      to hold in confidence and trust and shall execute the Company's standard
      form nondisclosure and confidentiality agreement so agreeing not to trade
      on the basis of material non-public



      information acquired from the Company or to disclose to third parties or
      use for purposes inimical to the Company's best interests any information
      provided to or learned by it in connection with the rights provided under
      this Section 6(a)(ii). The rights granted under this Section 6(a)(ii)
      shall terminate and be of no further force or effect upon such time as EIS
      or an affiliate is no longer entitled to nominate and elect one member to
      the Company's board of directors pursuant to the rights granted to such
      holder."

5.    Voting Matters/Shareholder Distributions for Taxes

The Letter Agreement, dated January 21, 1999, among JVP, Newco, Nascime, Elan
Corp and EIS (the "Letter Agreement") is hereby amended as of the Effective Date
as follows:

            (a) Paragraph 1 is hereby amended in its entirety to read as
follows:

      "1. At no time prior to June 30, 2004 shall the voting interest of Elan
      Corporation, plc (including its subsidiaries) (collectively, "Elan") in
      DOV be 10% or greater of the voting power of all shares of stock of DOV.
      The foregoing restriction shall automatically terminate and shall be of no
      further force or effect with respect to any shares of stock of DOV
      transferred or assigned to persons or entities other than Elan."

            (b) Paragraph 2 of the Letter Agreement is hereby deleted in its
entirety and shall be of no further force or effect.

6.    Third Party Beneficiary

Each Party acknowledges and agrees that EPIL II shall be deemed in all respects
to be a third party beneficiary of the agreements contained in this Schedule 6.1
with the same force and effect as if EPIL II were a party thereto with regard to
any securities of DOV or its Affiliates to which EPIL II is the holder of
record.
