WHEREAS, the Executive and the Company are parties to an employment agreement dated August 23, 2001 (the “Employment Agreement”);

WHEREAS, the Company has retained the services of a new Chief Financial Officer, and the parties hereto wish to address the rights, responsibilities, benefits and payments as a result of the foregoing;

WHEREAS, the Executive and the Company acknowledge and agree that after the date hereof his employment shall continue as an employee (and not as the Chief Financial Officer) until April 30, 2004, subject to the terms hereof;

WHEREAS, it is agreed by the parties that the Executive shall receive benefits comparable to those to which he would have been entitled pursuant to Section 7(a) of the Employment Agreement, as and to the extent expressly provided below; and

WHEREAS, it is agreed by the parties that the Executive shall receive certain additional benefits pursuant to the terms hereof, which benefits go beyond those to which he would have been entitled pursuant to Section 7(a) of the Employment Agreement or pursuant to any applicable plan, policy, or practice of the Company or pursuant to any prior agreement between the Company and the Executive, as and to the extent as expressly provided below.

NOW, THEREFORE, in consideration of the mutual covenants and commitments provided for

herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by both parties, the Executive and the Company hereby agree as follows:

1.                                       Employment Period.  The Executive hereby resigns as Chief Financial Officer of the Company, effective February 3, 2004. The Executive’s employment with the Company shall continue to (but not after) April 30, 2004 (the period commencing the date hereof and ending on April 30, 2004, or such earlier date as set forth in Section 2(b) hereof, the “Employment Period”).  Prior to the end of the Employment Period, the Executive will continue to perform such of his previous duties in the area of financial control and reporting as shall be assigned to him by the authorized officers of the Company, on a full-time, five days per week basis, for the Company, and otherwise in accordance with the Employment Agreement except as otherwise provided herein.  Until the end of the Employment Period, the Executive will be entitled to compensation and benefits as follows: (i) base salary at the rate of $225,000 per annum, subject to applicable withholding, payable bi-weekly in accordance with the Company’s normal business practices, (ii) expense reimbursement as provided in Section 3(e) of the Employment Agreement, (iii) continuation of the medical insurance in the same manner that has heretofore been provided pursuant to Section 3(f) of the Employment Agreement and (iv) seven days of paid vacation.  In addition, subject in all respects to Section 9 hereof, commencing immediately after the end of the Employment Period and continuing through August 31, 2004, the Executive shall continue to receive payments equal to the base salary that he would have received had he continued to be employed through such date (calculated based upon the Executive’s current base salary of $225,000 per annum), subject to applicable withholding, such payments to be paid at such times and in such manner as is applicable under the normal payroll practices in effect for continuing senior executives of the Company (provided that the first payment of base salary following the end of the Employment Period may be deferred until the Release Effectiveness Date (as defined in Section 9 hereof)).  In addition, on the Release Effectiveness Date, subject in all respects to Section 9 hereof, the Company shall pay the Executive a bonus of $133,333 in respect of 2004.  During the Employment Period, the Executive will continue to be an officer of the Company with the title of Vice

2

President. The Executive hereby tenders his resignation as of the last day of the Employment Period, and hereby resigns from any other corporate offices and board of director memberships with the Company and all affiliates thereof as of the last day of the Employment Period; the Executive acknowledges and agrees that, upon the end of the Employment Period, he shall take any further actions reasonably requested by the Company as may be necessary or appropriate further to reflect such resignations.

2.                                       Employment Agreement.

(a)                                  The Employment Agreement is terminated in its entirety effective as of the date of this Interim Employment Agreement, except that the following provisions of the Employment Agreement will survive termination: (i) Section 4, (ii) Sections 8(a), 8(b)(ii) and 8(e)-8(i) (together with any provisions in the Employment Agreement relating to the enforcement of Section 8 of the Employment Agreement) as provided below and (iii) Section 3(e) with respect to any expenses incurred prior to the end of the Employment Period and not theretofore reimbursed.  Without limiting the generality of the foregoing, no payment or benefit shall be made or otherwise arise under Section 7 or any other provision of the Employment Agreement by virtue of such termination.

(b)                                 From and after the date hereof, in no event shall Section 7 of the Employment Agreement apply to any termination of the Executive’s employment by the Executive.  Without limiting the generality of the foregoing, from and after the date hereof, Section 7(a) of the Employment Agreement shall not apply to any termination of employment by the Executive for Good Reason, and Sections 7(c) and 7(d) shall not apply to any termination of employment on account of death or disability.  In the event the Company terminates the Executive’s employment (with or without cause other than a Criminal Act (as defined in Section 10 below)) before the scheduled end of the Employment Period, or there is a termination of employment before the scheduled end of the Employment Period on account of the Executive’s death or disability or the Executive resigns for Good Reason (as defined below), then in each such case: (i) the end of the Employment Period for purposes of this Interim Employment Agreement shall be the date of such termination of employment, and (ii) this Interim Employment Agreement shall

3

otherwise apply in accordance with its terms (it being acknowledged that, in each of the foregoing circumstances, the Company will be required to make all payments provided for in Section 1, on the terms and conditions provided therein, and the Executive’s options and restricted stock shall vest as provided in Sections 3 and 4, on the terms and conditions provided therein).  For purposes of the preceding sentence, “Good Reason” shall mean (i) failure by the Company to comply with its obligations under the third sentence of Section 1 or (ii) a material breach by the Company of any other provision of this Interim Employment Agreement which is not cured within 30 days after notice of non-compliance  (specifying the nature of the non-compliance) has been given by the Executive to the Company.

3.   Options.

(a)                                  With respect to the options to purchase shares of common stock of the Company provided for by that certain option agreement between the Executive and the Company dated October 24, 2000, (i) 4,000 unvested and unexercisable options granted thereunder shall become vested and initially exercisable upon the date hereof  (in addition to the 12,000 options thereunder that have heretofore vested  and become exercisable on January 1, 2003 and January 1, 2004), (ii) any options not vested or exercisable on or before the end of the Employment Period (taking into account clause (i)), shall not be or become vested or exercisable and shall without any further action be forfeited forthwith, and (iii) such option agreement shall otherwise apply in accordance with its terms (subject to Section 3(c) hereof).

(b)                                 With respect to the options to purchase shares of common stock of the Company provided for by that certain option agreement between the Executive and the Company dated October 10, 2002, (i) 18,750 unvested and unexercisable options granted thereunder shall become vested and initially exercisable upon the date hereof, (ii) 18,750 unvested and unexercisable options granted thereunder shall become vested and initially exercisable on the Release Effectiveness Date, subject in all respects to Section 9 hereof, (iii) any options not vested or exercisable on or before the end of the Release Effectiveness Date (taking into account clause (i) and in accordance with clause (ii) above) shall not be or

4

become vested or exercisable and shall without any further action be forfeited forthwith, and (iv) such option agreement shall otherwise apply in accordance with its terms (subject to Section 3(c) hereof).

(c)                                  The Company agrees that the provisions of Section 2.5(b) of the Company’s Amended 1997 Stock Option and Incentive Plan (the “Plan”) are not applicable to the Executive’s options.

(d)                                 The Company agrees that any shares issued to the Executive pursuant to the exercise of his options will not bear any restrictive legends.

4.                                       Restricted Stock.  The Executive was granted 15,000 shares of restricted stock as provided in Section 3(d) of the Employment Agreement (it being acknowledged that such Section constitutes the sole written agreement evidencing or pertaining to such grant).  Prior to the date hereof, 4,500 of such shares vested pursuant to the terms of the grant.  The Company agrees that, effective on the Release Effectiveness Date (as defined in Section 9), subject in all respects to Section 9 hereof, the remaining 10,500 of such shares shall immediately and irrevocably vest.  With respect to such shares, the Company shall also pay the Executive an additional cash amount, intended to serve generally as a tax gross-up, equal to 40% of the value of the shares included in the Executive’s taxable income on such date.  Termination of the Executive’s employment by the Company (with or without cause other than a Criminal Act) will not cause the Executive to forfeit any of his restricted stock.  The Company agrees that it will remove any restrictive legends from the certificates representing all such restricted shares that are vested.

5.                                       COBRA.  Following the end of the Employment Period, the Executive will be given the opportunity to continue under the Company’s group health plans, as may be required, and to the extent provided, by the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”).  The Company agrees, subject in all respects to Section 9 hereof, to pay the Executive’s COBRA premiums through August 31, 2004, other than such amounts as the Executive would have had to pay had he continued to be employed.

6.                                       Transfer of Responsibilities; Cooperation.  Without limiting Section 8(h) of the Employment Agreement or the related provisions of Sections 2 and 9 hereof, for no additional compensation, the Executive expressly agrees to cooperate fully from the date hereof through the end of the Employment Period in the transfer of his responsibilities as Chief Financial Officer of the Company, and any other responsibilities or duties that he performed in connection with his employment at the Company to the individual(s) designated by the Company.  The Executive acknowledges that the transition will require travel outside of New York City.  The Executive expressly agrees that following the last day of the Employment Period, he shall fully cooperate with any other reasonable requests made by the Company, but in no event shall such requests be at any cost to the Executive nor require any material time commitment to the Company, as reasonably determined by the Executive.

7.                                       Confidentiality.  The Executive agrees that he will keep the terms of this Interim Employment Agreement confidential, except that he may disclose this Interim Employment Agreement to or discuss this Interim Employment Agreement with his spouse, attorney, financial advisor and as may be required by law. The Company agrees that it will keep the terms of this Interim Employment Agreement confidential, except that the Company may discuss this Interim Employment Agreement with or disclose this Interim Employment Agreement to its attorneys, trustees, officers, agents, and as may be required by law.  Each party agrees that it shall advise any such persons with whom it discusses or to whom it discloses this Interim Employment Agreement of the existence and requirements of this confidentiality provision, and shall instruct any such person that such person shall not disclose the existence of this Interim Employment Agreement or its terms to any other person.  If the Company determines that this Interim Employment Agreement must be filed as an exhibit to an SEC report, or that it must disclose the terms hereof in any public SEC filing, the Company may do so, whereupon the obligations of the Company and the Executive under this Section 7 will terminate.

8.                                       Prohibited Activities.  The provisions of Sections 8(a), 8(b)(ii) and 8(e)-8(i) of the Employment Agreement (the “Restrictive Covenants”) are hereby incorporated into this Interim

6

Employment Agreement by reference as though stated in full herein (including any provisions in the Employment Agreement relating to the enforcement thereof), and (together with any provisions in the Employment Agreement relating to the enforcement thereof) shall survive termination of employment and the termination of the Employment Agreement in accordance with the terms of the Restrictive Covenants.

9.                                       General Release by Executive; Certain Other Matters.  It is expressly understood and agreed that, without limiting the Executive’s obligations hereunder, the Executive’s Specified Rights (as defined below) are subject entirely and in all respects to (i) the Executive’s provision, at or after the close of business on the last day of the Employment Period and not more than seven business days after the last day of the Employment Period, of a Release in the form attached hereto as Exhibit A (the “Release”) and (ii) the Release’s becoming irrevocable as confirmed by the Executive’s written confirmation, in the form attached hereto as Exhibit B delivered to and received by the Chief Executive Officer of the Company at the principal place of business of the Company, that the Release has not been revoked (the “Confirmation”).  The Confirmation shall be delivered (i) not before the expiration of the seven-day revocation period provided for in Section 4 of the Release and (ii) not after seven days have elapsed after such expiration of such seven-day period.  The date on which the Confirmation is delivered in accordance with the preceding sentence is referred to as the “Release Effectiveness Date.”  If the Release Effectiveness Date does not occur in accordance with the second preceding sentence, then the Executive will not have the following rights and benefits provided for by this Interim Employment Agreements (the “Specified Rights”): (i) the right to receive a bonus as provided in Section 1 hereof; (ii) the right to continue to be receive payments after the end of the Employment Period and through August 31, 2004 as provided in Section 1 hereof; (iii) the vesting of 18,750 options as provided in clause (ii) of Section 3(b) hereof; (iv) the vesting of 10,500 shares of restricted stock as provided in Section 4 hereof and (v) the right to have COBRA premiums paid as provided in Section 5.  The Executive is hereby advised to seek advice of counsel in connection with the Release, and acknowledges and agrees that he has otherwise had the opportunity to seek advice of counsel in connection with this Interim Employment Agreement.
