ACCOUNT CONTROL AGREEMENT

ACCOUNT CONTROL AGREEMENT (this “ Agreement ”), dated as April 25, 2005, by and among Wachovia Bank, National Association, as depository bank (“ Depository Bank ”), Portside Growth & Opportunity Fund, a company organized under the laws of the Cayman Islands (“ Secured Party ”), in its capacity as agent for the Buyers (as defined below), and Millennium Cell Inc., a Delaware corporation (the “ Company ”).

Depository Bank acknowledges that as of the date hereof, it maintains in the name of the Company a certain deposit account (Account Name: __________________ and No.#_________) (collectively with all monies on deposit in such deposit account and all certificates and instruments, if any, representing or evidencing such deposit account, the “ Account ”). Except as otherwise set forth herein, such deposit account is governed by the terms and conditions of the Deposit Agreement and Disclosures for Non-Personal Accounts or other comparable deposit account agreement published by Depository Bank from time to time (the “ Deposit Agreement ”).

In connection with the Securities Purchase Agreement, dated as of April 20, 2005 (the “ Securities Purchase Agreement ”), by and among the Company and the Buyers, the Buyers have purchased 10,000 shares (the “ Preferred Shares ”) of the Company’s Series C Convertible Preferred Stock, par value $.001 per share. The Buyers shall be entitled to receive dividends (the “ Dividends ”) on such Preferred Shares in accordance with the terms set forth in the Certificate of Designations, Preferences and Rights of Series C Convertible Preferred Stock (the “ Certificate of Designations ”). Capitalized terms used herein and not otherwise defined shall have the meanings assigned to such terms in the Certificate of Designations.

To secure the payment of Dividends under the Certificate of Designations and certain other obligations of the Company under the Certificate of Designations, the Company hereby informs Depository Bank that it has granted to the Buyers a security interest in the Account pursuant to the Security Agreement with the Secured Party, dated the date hereof (the " Security Agreement "). The parties desire to enter into this Agreement in order to set forth their relative rights and duties with respect to the Account.

NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1.   Account Funds . The Company hereby represents and warrants to Secured Party that the Company has deposited into the Account cash in the amount of $1,900,000. In connection with the payment of Dividends in cash on any Dividend Date pursuant to and in accordance with the Certificate of Designations, the Company shall deliver to Depository Bank written instructions not later than five business days prior to each Dividend Payment Date, with a copy of such notice to Secured Party, directing the release to the holders of the Preferred Shares on such Dividend Payment Date from the Account of an amount in cash equal to the value of the Dividends paid in cash to the holders of the Preferred Shares with respect to such Dividend Date. Such notice shall contain payment amounts and wire instructions for each holder of the Preferred Shares as of such Dividend Payment Date. In connection with the payment of Dividends in capital stock of the Company on any Dividend Date or the conversion of Preferred Shares prior to such Dividend Date, the Company shall deliver to Depository Bank written instructions not later than five business days prior to each Dividend Payment Date, with a copy of such notice to Secured Party, directing the release to the Company on the tenth Business Day following such Dividend Date of an amount in cash equal to the value of Dividends paid in capital stock of the Company to holders of the Preferred Shares with respect to such Dividend Date or the ratable amount of Dividends corresponding to any Preferred Shares no longer outstanding as of such Dividend Date. For example, if $2,000,000 of a total of $8,000,000 in Preferred Shares are converted during a quarter, then an amount equal to 1/4 of the remaining funds in the account will be refunded to the Company less the amount of dividends paid for that quarter on such tenth Business Day following such Dividend Date. Except for withdrawals on the dates and for the amounts specified above and pursuant to Section 10(c), the Company agrees that it shall not be entitled to request withdrawals from the Account. The Company hereby covenants and agrees that the Account shall be exclusively used as the deposit account in connection with the transactions contemplated by the Transaction Documents and shall not be used for any other purpose.

2.   No Liens on Account . Depository Bank represents that it has not received written notice of any current claim to the Account from any person not a party to this Agreement. Depository Bank has not entered into and will not enter into any agreement with any person other than the Company and Secured Party by which Depository Bank is obligated for any reason to comply with instructions from such other person as to the disposition of funds in or from the Account other than those approved in writing as provided herein by the Company and/or Secured Party. Depository Bank will not agree that any person other than the Company or Secured Party is Depository Bank’s customer with respect to the Account. Depository Bank will not exercise or claim any security interest, lien, right of set-off, deduction, recoupment or banker’s lien or any other interest in or against the Account and Depository Bank hereby waives any such interest, right or lien which it may have against the Account, except that Depository Bank may offset and charge such Account for all service charges, fees, expenses, adjustments or correction of posting or encoding errors and other items normally chargeable to any similar deposit account at Depository Bank, whether incurred before or after the date of this Agreement.

3.   Control of Account . The Company hereby authorizes and directs Depository Bank to comply, and Depository Bank agrees to comply, with instructions originated by Secured Party in accordance with this Agreement and the Security Agreement directing the disposition of funds from time to time in the Account or as to any other matters relating to the Account without further consent by the Company, but subject to the terms of this Agreement and the Security Agreement. Depository Bank shall permit transactions in the Account by notices given in accordance with Section 1 hereof (it being understood that the Depository Bank shall have no obligation to verify the accuracy of such notices) at the direction of the Company or the Company’s authorized representatives until such time as Secured Party delivers written notice (the “ Notice of Exclusive Control ”) to Depository Bank that (i) the Company has failed to pay any Obligation (as defined in the Security Agreement) when due, whether in cash or in kind as permitted pursuant to the Certificate of Designation, and such failure to pay continues for a period of at least five (5) Business Days, or a Liquidation Event has occurred with respect to the Company and (ii) Secured Party is thereby exercising exclusive control over the Account. The Company and Secured Party acknowledge and agree that Secured Party shall not be entitled to deliver a Notice of Exclusive Control until a Company fails to pay any Obligation (as defined in the Security Agreement) when due, whether in cash or in kind as permitted pursuant to the Certificate of Designation, and such failure to pay continues for a period of at least five (5) Business Days, or a Liquidation Event has occurred. Not later than the next business day after the date of receipt of the Notice of Exclusive Control with respect to items presented through the Federal Reserve System, local clearinghouses, or automated clearinghouses, and not later than the second business day after the date or receipt of the Notice of Exclusive Control with respect to items presented for payment or acceptance over the counter, Depository Bank will cease complying with orders or directions concerning disposition of funds in the Account initiated by the Company or the Company’s authorized representatives. Any Notice of Exclusive Control received after 2:00 p.m. New York time shall be deemed to have been received on the next business day. Depository Bank will use the Fedwire system to make any funds transfer from the Account to any account specified by Secured Party in accordance herewith unless for any reason the Fedwire system is unavailable, in which case Depository Bank will determine the funds transfer system to be used in making each funds transfer and the means by which each transfer will be made.

4.   Statements and Notices of Adverse Claims . At Secured Party’s written request, Depository Bank will furnish in accordance with its standard practices copies of all correspondence, notices, and account statements (but not canceled checks) or other information which Depository Bank is otherwise obligated to send to the Company
