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.

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.
