EIS is a corporation duly organized and validly existing and in good standing under the laws of Bermuda and has all requisite corporate power and authority to own and lease its properties, to carry on its business as presently conducted and as proposed to be conducted and to consummate the transactions contemplated hereby. EIS is qualified and in good standing to do business in each jurisdiction in which the nature of the business conducted or the property owned by it requires such qualification, except where the failure to so qualify would not reasonably be expected to have a Material Adverse Effect on EIS. (b) AUTHORIZATION OF AGREEMENT. EIS has full legal right, power and authority to execute and deliver this Agreement and each other Transaction Document to which it is a party, and to purchase and accept the Notes, and perform its obligations hereunder and 7 <Page> thereunder, which have been duly authorized by all requisite corporate action.

EIS has not been formed solely for the purpose of entering into the transactions described herein and therein and is acquiring the Securities for investment for its own account, not as a nominee or agent, and not with the view to, or for resale, distribution or fractionalization thereof, in whole or in part, and no other person has a direct or indirect interest, beneficial or otherwise in the Securities; provided, that EIS shall be permitted to convert or exchange such Securities. (ii) EIS does not plan to enter into any contract, undertaking, agreement or arrangement with any person to sell, transfer or pledge the Shares.

EIS understands the risks of, and other considerations relating to, a purchase of the Securities, including the risk of losing its entire investment. EIS acknowledges that it has prior investment experience, including investments of a speculative nature in non-registered or unlisted securities, and it has read all of the documents furnished or made available by the Company to it and has evaluated the merits and risks of such an investment. EIS recognizes the highly speculative nature of this investment and is able to bear the total economic risk it hereby assumes. (f) BROKERS OR FINDERS. EIS has not retained any investment banker, broker or finder in connection with the transactions contemplated by the Transaction Documents. (g) LITIGATION. There is no litigation or governmental, administrative, arbitration or other action or proceeding or governmental investigation pending or threatened against EIS or any director or officer or employee thereof that, if determined adversely to EIS, (i) may have a Material Adverse Effect on EIS or any of its properties or assets or (ii) disturb or challenge the validity or performance of this Agreement or the other Transaction Documents to which EIS is a party.

(ii) Prior to issuing any press release or public disclosure in respect of this Agreement or the transactions contemplated hereby, the party proposing such issuance shall obtain the consent of the other party to the contents thereof, which consent shall not be unreasonably withheld or delayed; it being understood that if such second party shall not have responded to such consent request within one business day, such consent shall be deemed given.

EIS shall have the right (i) to convert the Convertible Note into shares of Common Stock as set forth in the Convertible Note and (ii) to convert or exchange the Exchangeable Note into shares of Common Stock as set forth in the Exchangeable Note. SECTION 7. SURVIVAL AND INDEMNIFICATION. (a) SURVIVAL PERIOD. The representations and warranties of the Company and EIS contained herein shall survive for a period of 15 months from and after the date hereof. (b) INDEMNIFICATION. In addition to all rights and remedies available to the parties hereto at law or in equity, the parties (each, in such capacity, AN "INDEMNIFYING PARTY"; together, "INDEMNIFYING PARTIES") shall indemnify each other as corporate entities (EIS and the Company), its stockholders, officers, directors and assigns, their affiliates, and its affiliates' stockholders, officers, directors, employees, agents, representatives, successors and assigns (collectively, the "INDEMNIFIED PERSON"), and save and hold each Indemnified Person harmless from and against and pay on behalf of or reimburse each such Indemnified Person, as and when incurred, for any and all loss, liability, demand, claim, action, cause of action, cost, damage, deficiency, tax, penalty, fine or expense, whether or not arising out of any claims by or on behalf of such Indemnified Person or any third party, including interest, penalties, reasonable attorneys' fees and expenses and all amounts paid in investigation, defense or settlement of any of the foregoing (collectively, "LOSSES"), that any such Indemnified Person may suffer, sustain incur or become subject to, as a result of, in connection with, relating or incidental to or by virtue of: (i) any misrepresentation or breach of warranty on the part of the Indemnifying Party in the case of the Company under Section 2 of this Agreement or in the case of EIS under Section 3 of this Agreement or any of the other Transaction Documents; or (ii) any nonfulfillment, default or breach of any covenant or agreement on the part of the Indemnifying Party under Section 4 of this Agreement or any of the other Transaction Documents. (c) MAXIMUM RECOVERY. Notwithstanding anything to this Agreement to the 12 <Page> contrary, in no event shall the Indemnifying Parties be liable in the case of the Company for indemnification under this Section 7 in an amount in excess of the aggregate of the purchase price paid for the Shares and the amounts advanced and not repaid under the Notes or in the case of EIS for indemnification hereunder in an amount in excess of such same aggregate. No Indemnified Person shall assert any such claim unless Losses in respect thereof incurred by any Indemnified Person, when aggregated with all previous Losses hereunder, equal or exceed U.S.$50,000, but at such time that an Indemnified Person is entitled to assert a claim, such claim shall include all Losses covered by this Section 7. (d) EXCEPTION. Notwithstanding the foregoing, upon judicial determination that is final and no longer appealable, that the act or omission giving rise to the indemnification set forth above resulted primarily out of or was based primarily upon the Indemnified Person's negligence (unless such Indemnified Person's negligence was based upon the Indemnified Person's reliance in good faith upon any of the representations, warranties, covenants or promises made by the Indemnifying Party herein) the Indemnifying Party shall not be responsible for any Losses sought to be indemnified in connection therewith, and the Indemnifying Party shall be entitled to recover from the Indemnified Person all amounts previously paid in full or partial satisfaction of such indemnity, together with all costs and expenses (including reasonable attorneys fees) of the Indemnifying Party reasonably incurred in connection with the Indemnified Person's claim for indemnity, together with interest at the rate per annum publicly announced by Morgan Guaranty Trust Company as its prime rate from the time of payment of such amounts to the Indemnified Person until repayment to the Indemnifying Party. (e) INVESTIGATION. All indemnification rights hereunder shall survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby to the extent provided in Section 7(g) below, irrespective of any investigation, inquiry or examination made for or on behalf of, or any knowledge of the Indemnified Person or the acceptance of any certificate or opinion. (f) CONTRIBUTION. If the indemnity provided for in this Section 7 shall be, in whole or in part, unavailable to any Indemnified Person, due to Section 7(b) being declared unenforceable by a court of competent jurisdiction based upon reasons of public policy, so that Section 7(b) shall be insufficient to hold each such Indemnified Person harmless from Losses which would otherwise be indemnified hereunder, then the Indemnifying Party and the Indemnified Person shall each contribute to the amount paid or payable for such Loss in such proportion as is appropriate to reflect not only the relative benefits received by the Indemnifying Party on the one hand and the Indemnified Person on the other, but also the relative fault of the Indemnifying Party and be in addition to any liability that the Indemnifying Party may otherwise have. The indemnity, contribution and expense reimbursement obligations that the Indemnifying Party has under this Section 7 shall survive the expiration of the Transaction Documents. The parties hereto further agree that the indemnification and reimbursement commitments set forth in this Agreement shall apply whether or not the Indemnified Person is a formal party to any such lawsuit, claims or other proceedings. (g) LIMITATION. No claim shall be brought by an Indemnified Person in respect 13 <Page> of any misrepresentation or breach of warranty under this Agreement after one year from the date hereof; and any claim for nonfulfillment, default or breach of any covenant shall be brought within one year of the date of that such Indemnified Person became aware or should have become aware of the nonfulfillment, default or breach. Except as set forth in the previous sentence and in Section 7(c) above, this Section 7 is not intended to limit the rights or remedies otherwise available to any party hereto with respect to this Agreement or the Transaction Documents. SECTION 8. NOTICES. All notices, demands and requests of any kind to be delivered to any party in connection with this Agreement shall be in writing and shall be deemed to have been duly given if personally or hand delivered or if sent by an internationally-recognized overnight delivery or by registered or certified airmail, return receipt requested and postage prepaid, addressed as follows: (i) if to the Company, to: DOV Pharmaceutical Inc.

The entire principal amount of this Note shall be disbursed by EIS to DOV on the date hereof. SECTION 1. Securities Purchase Agreement and Joint Development and Operating Agreement. This Note is issued pursuant to a Securities Purchase Agreement dated an of the date hereof by and between DOV and EIS (as amended at any time, the "SECURITIES PURCHASE AGREEMENT", and is intended to be afforded the benefits thereof, including the representations 1 <Page> and warranties set forth therein. DOV shall use the proceeds of the issuance and sale of this Note solely in accordance with the provisions set forth therein and in a certain Joint Development and Operating Agreement, dated as of the date hereof (as amended at any time, the "JOINT DEVELOPMENT AND OPERATING AGREEMENT"), by and among Elan Corporation, plc, an Irish public limited company and the parent corporation of EIS, EIS, DOV, DOV Newco, Ltd., a Bermuda exempted limited company ("BERMUDA NEWCO") and Nascime Limited, an Irish private limited company ("Ireland Newco"), and as described in Section 5 below. SECTION 2. PAYMENTS AND COVENANTS. (a) Unless earlier converted in accordance with the terms of Section 3 below, exchanged in accordance with Section 4 below, or prepaid in accordance with the terms hereof, the entire outstanding principal amount of this Note, together with any accrued and unpaid interest thereon, shall be due and payable on the Maturity Date. (b) Accrued interest hereon shall not be paid in cash, but shall be capitalized and added to principal amount outstanding hereunder on each Compounding Date. (c) This Note may not be prepaid by DOV without EIS's prior written consent. (d) During the time that this Note remains outstanding, DOV shall not, without the prior written consent of the Holder, (i) incur or permit to exist any indebtedness by DOV or any of DOV's subsidiaries senior or PARI PASSU with to the indebtedness represented by this Note; provided, that DOV may incur (A) senior indebtedness in the form of working capital lines of credit and financing or similar leasing arrangements up to $1 million (including the aggregate available amount of any undrawn lines or similar credit financings) and (B) senior indebtedness, without limit on a PARI PASSU basis, funded by banks, bank holding companies, insurance companies and other investors customarily defined as institutional investors, it being understood that the amounts described in clauses {A) and (B) shall be additive, SECTION 3. CONVERSION. (a ) CONVERSION RINHT. (i) From and after the date that is two years after the Original Issue Date and until this Note is repaid in full, the Holder shall have the right from time to time, in its sole discretion, to convert the outstanding principal amount and accrued and unpaid interest then-outstanding hereunder into such number of shares of the common stock of DOV par value $.0001 per share (the "DOV COMMON STOCK"), that shall be obtained by dividing the sum of the outstanding principal amount of this Note and all accrued interest thereon by the price (the "Benchmark Price") equal to the lesser of (A) U.S. $6.44 and (B) the product of (x) 1.75 and (y) due per share price, in the case of DOV Common Stock, or the initial per share conversion price, in the case of equity securities convertible, exchangeable or exercisable for or into shares of DOV Common Stock, in each case, in the next BONA FIDE financing that is consummated by DOV or its affiliates after the Original Issue Date and within 18 months thereof; provided, that if a transaction giving rise to the calculation in (E) shall not have occurred, then, in such event, the Benchmark Price shall be the amount set forth in (A). In the event that, within 18 months of the 2 <Page> Original Issue Closing Date and after conversion in whole or part of this Note, DOV issues any equity securities (or rights, options, warrants or other securities exchangeable, convertible or exercisable for or into equity securities) at an effective price per share that is less than the Benchmark Price, DOV shall have the obligation (to be implemented upon the request of EIS at any time thereafter during the term of this Note), from and after the date that is the date of closing of such offering, to issue to EIS, for no additional consideration, pro-rats additional shares of voting and non-voting DOV Common Stock so that such additional shares, when added to the DOV Common Stock issued upon such conversion, causes the aggregate number of shares of such DOV Common Stock issued upon such conversion to be issued as if the denominator in such formula were the Benchmark Price. Such additional issuance shall be applicable with respect to accrued and unpaid interest if EIS has exercised the Exchange Right (as defined below). (ii) EIS shall notify DOV in writing of its intention to exercise the conversion. Upon 10 days of receipt of the notice, DOV shall issue stock certificates to EIS representing the aggregate number of shares of DOV Common Stock EIS shall own after the conversion. Upon such exercise, EIS shall, if necessary, exchange with DOV, the DOV Common Stock certificates currently in its possession for the DOV Common Stock certificates which reflect the aggregate number of shares of DOV common Stock transferable to EIS after EIS exercises the conversion. (b) RECLASSIFICATION, ETC. In case of any reclassification, reorganization, change or conversion of securities of the class issuable upon conversion of the outstanding principal amount and accrued and unpaid interest then-outstanding hereunder (other than a change in par value, or from par value to no par value), or (ii) any consolidation of DOV with or into another entity (other than a merger or consolidation with another entity in which DOV is the acquiring and the surviving entity and that does not result in any reclassification or change of outstanding securities issuable upon the conversion of the outstanding principal amount and accrued and unpaid interest then-outstanding hereunder), or (iii) any sale of all or substantially all the assets of DOV, then DOV, or such successor or purchasing entity, as the case may be, shall duly execute and deliver to the Holder a new Note or a supplement hereto (in form and substance reasonably satisfactory to the Holder), so that the Holder shall have the right to receive, at a total purchase price not to exceed that payable upon the conversion of the outstanding principal amount and accrued and unpaid interest then-outstanding hereunder, and in Lieu of the shares of Common Stock theretofore issuable upon the conversion the outstanding principal amount and accrued and unpaid interest then out-standing hereunder, the kind and amount of shares of stock and other securities, receivable upon such reclassification, reorganization, change or conversion by a holder of the number of shares of Common Stock then issuable under this Note. Such new Note shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 3. The provisions of this Section 3(b) shall similarly attach to successive reclassifications, reorganizations, changes, and conversions. (c) SUBDIVISION OR COMBINATION OF SHARES. If DOV at any time during which there is any outstanding principal amount and accrued and unpaid interest then-outstanding hereunder shall subdivide or combine its Common Stock, (i) in the case of a subdivision, the Benchmark Price shall be proportionately decreased and the number of Shares issuable hereunder 3 <Page> shall be proportionately increased, and (ii) in the case of a combination, the Benchmark Price shall be proportionately increased and the number of Shares issuable hereunder shall be proportionately decreased. (d) NO IMPAIRMENT. DOV will not, by amendment of its certificate of incorporation or bylaws or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by DOV, but will at all times in good faith assist in the carrying out of all the provisions of this Section 3 and in the taking of all such action as may be necessary or appropriate in order to protect the rights of EIS against impairment. (e) NOTICE OF ADJUSTMENTS. Whenever the Benchmark Price or the number of Shares issuable hereunder shall be adjusted pursuant to this Section 3, DOV shall prepare a certificate setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated. Such certificate shall be signed by its chief financial officer and shall be delivered to EIS. (f) FRACTIONAL SHARES. No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares DOV shall make a cash payment therefor based on the fair market value of the Common Stock on the date of exercise as reasonably determined in good faith by DOV's Board of Directors. (g) CUMULATIVE ADJUSTMENTS. No adjustment in the Benchmark Price shall be required under this Section 3 until cumulative adjustments result in a concomitant change of 1% or more of the Benchmark Price or in the number of shares of Common Stock issuable upon conversion of the outstanding principal amount and accrued and unpaid interest then-outstanding hereunder, as in effect prior to the last such adjustment; provided, however, that any adjustments which by reason of this Section 3 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 3 shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. (h) NOTICE OF CONVERSION. The Holder shall be entitled to exercise the rights of conversion as described in this Section 3 upon 30 days' notice to DOV, such notice to be in the form attached hereto as EXHIBIT B. SECTION 4. EXHIBIT RIGHT (a) If no portion of the original principal amount hereof (as opposed to accrued interest) has been converted, this Note shall be exchangeable (the "Newco Exchange Right") at any time during the term for a number of additional "B" Shares of Bermuda Newco, par value $1.00 per share (together with the "A" Shares the "NEWCO COMMON STOCK") so that the aggregate number of B Shares of Bermuda Newco originally issued to EIS on the Original Issue Date and the shares issued or transferred to EIS in connection with such exchange shall be equal to the aggregate number of "A" Shares in Bermuda Newco originally issued to and subscribed for by 4 <Page> DOV on the Original Issue Date less the number of "B" Shares, if any, transferred to EIS by DOV in connection with the exercise of the Newco Exchange Right. The parties shall make appropriate arithmetic adjustments to any share issuance to give effect to the foregoing in the cases of issuance of new shares of Bermuda Newco rather than transfers by DOV or its affiliates of existing shares to EIS. In the event of the exercise of die Newco Exchange Right, (x) the outstanding principal amount of this Note shall be cancelled, and shall no longer be entitled to any exchange right for shares of DOV Common Stock and (y) the accrued interest on this Note shall continue to carry the rights attributable thereto (including conversion into DOV Common Stock), other than the Newco Exchange Right. As provided in the Joint Development and Operating Agreement prior to and upon any such exchange, EIS shall have a like interest (proportionate to its then shareholding interest) in any additional or other capital in Bermuda Newco. (b) EIS shall notify DOV and Bermuda Newco writing of its intention to exercise the Newco Exchange Right. Upon 1O days of receipt of the notice, Bermuda Newco shall issue new stock certificates to EKS representing the aggregate number of shares of Newco Common Stock EIS shall own after the exercise of the Newco Exchange Right. Upon such exercise, EIS shall, if necessary, exchange with Bermuda Newco, the Newco Common Stock certificates currently in its possession for the Newco Common Stock certificates which reflect the aggregate number of shares of Newco Common Stock transferable or issuable to EIS after EIS exercises the Newco Exchange Right. (c) In the event that EIS exercises the Newco Exchange Right, EIS shall, within 10 days of the date of the consummation of such transaction, cause to be paid to or as directed by DOV an amount equal to the excess of (A) the percentage of Bermuda Newco then owned by EIS (assuming such exchange) but not in excess of 50%, of the aggregate amount of development and related funding contributed or paid to Bermuda Newco by DOV and EIS (or their respective affiliates) from and after the Original Issue Date over (B) the amount described in (A) above that was paid by EIS and its affiliates; together with interest thereon at a rate per annum equal to the lesser of (x) 7% and (y) the maximum rate of interest permitted by applicable law from and after the Original Issue Date, compounded on a semi-annual basis. (d) In no event shall the amount determined in accordance with subsection (a) above exceed the aggregate principal amount issued hereunder and accrued interest thereon. SECTION 5. USE OF PROCEEDS.

SECTION 1. SECURITIES PURCHASE AND JOINT DEVELOPMENT AND OPERATING AGREEMENTS; DISBURSEMENTS. (a) This Note is issued pursuant to a securities purchase agreement dated as of the date hereof by and between DOV and EIS (as amended at any time, the "SECURITIES PURCHASE AGREEMENT"). This Note is the Convertible Note referred to in the Securities Purchase Agreement and DOV and Holder are intended to be afforded the benefits thereof, including the representations and warranties set forth therein.

In the event that within IS months of the Closing and after conversion in whole or in part of this Note, DOV issues any equity securities (or rights, options, warrants or other securities exchangeable, convertible or exercisable for or into equity securities) at an effective price per share that is less than the Benchmark Price, DOV shall have the obligation (to be implemented at the request of EIS at any time during the six year term of this Note), from and after the date that is the date of closing of such offering, to issue to EIS, for no additional consideration, pro-rata additional shares of voting and non-voting Common Stock so that such additional shares, when added to the Common Stock issued upon conversion, causes the aggregate number of shares of such Common Stock issued upon such conversion to be issued as if the denominator in such formula were the Benchmark Price. (ii) EIS shall notify DOV in writing of its intention to exercise the conversion. Upon 10 days of receipt of the notice, DOV shall issue stock certificates to EIS representing the aggregate number of shares of Common Stock EIS shall own after the conversion.

(d) NO IMPAIRMENT. DOV will not, by incorporation of its certificate of incorporation or bylaws or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by DOV, but will at all times in good faith assist in the carrying out of all the provisions of this Section 3 and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder against impairment. (e) NOTICE OF ADJUSTMENTS. Whenever the Benchmark price or the number of Shares issuable hereunder shall be adjusted pursuant to this Section 3, DOV shall prepare a certificate setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated. Such certificate shall be signed by its chief financial officer and shall be delivered to the holder of this Note. (f) FRACTIONAL SHARES. No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares DOV shall make a cash payment therefor based on the fair market value of the Common Stock on the date of exercise as reasonably determined in good faith by DOV's Board of Directors. (g) CUMULATIVE ADJUSTMENTS. No adjustment in the Benchmark Price shall be required under this Section 3 until cumulative adjustments result in a concomitant change of 1% or more of the Benchmark Price or in the number of shares of Common Stock issuable upon conversion of this Note as in effect prior to the last such adjustment; provided, however, that any adjustments which by reason of this Section 3 are not required to be made shall be carried forward and taken into account in any subsequent adjustment.
