                              W I T N E S S E T H:

         WHEREAS, the Company has, on the date of this Instrument of Grant,
granted Optionee a non-qualified stock option to purchase from the Company
shares of the Company's common stock, par value $.01 per share ("Common Stock");

         WHEREFORE, the Company does hereby grant to Optionee the following
Option:

1.   Stock Option. Subject to the terms and conditions set forth in this
     Instrument of Grant, the Company hereby grants to the Optionee a
     non-qualified stock option (the "Option") to purchase from the Company
     seventy five thousand (75,000) shares (the "Optioned Shares") of Common
     Stock at an exercise price (the "Exercise Price") of six and 50/100 dollars
     ($6.50) per share, being the fair market value per share of Common Stock on
     the date of grant. The number of Optioned Shares being exercised at any
     particular time multiplied by the Exercise Price shall be hereinafter
     referred to as the "Purchase Price."

2.   Exercise Period.  This Option is exercisable cumulatively, as to thirty
     seven thousand five hundred (37,500) shares on February 28, 2001 and as to
     the remaining thirty seven thousand five hundred (37,500) shares on
     February 28, 2002, and, to the extent that it is exercisable, it may be
     exercised in whole at any time and in part from time, during the period
     (the "Exercise Period") commencing on the date it become exercisable and
     ending at 5:00 P.M. New York City time on February 28, 2005; provided,
     however, that if such date is a day on which banks in the City of New York
     are authorized or permitted to be closed, then the Exercise Period shall
     end at 5:00 P.M. New York City time on the next day which is not such a
     day.  Notwithstanding the foregoing, if the Optionee's employment is
     terminated pursuant to Paragraph 3(d) or 3(e) of Optionee's employment
     agreement dated February 1, 2000, the option shall become immediately
     exercisable in full.

3.   Termination. This Option shall terminate, and Optionee shall have no
     further rights under this Option, at the expiration of the Exercise Period;
     provided, however; that in the event of the Optionee's death, this Option
     may be exercised, to the extent exercisable on the date of death, during
     the one year period following the date of death, but not later then the
     last day of the Exercise Period.

4.   Manner of Exercise.

(a)  The Option shall be exercised by written notice of exercise in the form of
     Exhibit A to this Instrument of Grant addressed to the Company and signed
     by the Optionee and delivered to the Company along with this Instrument of
     Grant and payment in full of the Purchase Price of the Optioned Shares as
     to which the Option is being exercised. If the Option is exercised in part
     only, the Company will either issue a new Instrument of Grant with respect
     to the unexercised portion of the Option or shall make a notation on this
     Instrument of Grant reflecting the partial exercise.

(b)  The Purchase Price is payable by certified or official bank check or by
     personal check; provided, however, that if payment is made by check, no
     Optioned Shares shall be issued to Optionee until the Company has been
     advised by its bank that the check has cleared.



(c)  The Option may also be exercised by the delivery to the Company of shares
     of Common Stock having a fair market value, as of the date of exercise,
     equal to the Purchase Price of the Optioned Shares to the extent that the
     Option is being exercised.

(d)  The Optioned Shares, when issued upon exercise of the Option, will be duly
     and validly authorized and issued, fully paid and non-assessable.

5.   Adjustment Provisions. The number of shares of Common Stock and the
     Exercise Price shall be adjusted in accordance with generally accepted
     accounting principles in the event of a stock dividend, stock split, stock
     distribution, reverse split or other combination of shares,
     recapitalization or otherwise, which affects the Common Stock.

6.   Transferability. The Option is not transferable by the Optionee except, in
     the event of Optionee's death or incompetence, the Option may be exercised
     by Optionee's legal representative or by the persons to whom the Option is
     transferred by will or the laws of descent and distribution.

7.   No Rights As a Stockholder. The Optionee shall have no interest in and
     shall not be entitled to any voting rights or any dividend or other rights
     or privileges of a stockholder of the Company with respect to any shares of
     Common Stock issuable upon exercise of this Option prior to the exercise of
     this Option and payment of the Purchase Price of the Optioned Shares.

8.   No Right to Continued Employment. Nothing in this Instrument of Grant shall
     be construed (a) as an employment agreement or an agreement to engage the
     Optionee as a consultant, or (b) to grant Optionee any rights to continue
     as an employee or consultant of the Company or of a parent, subsidiary or
     affiliate of the Company.

9.   Legality.  Anything in this Option to the contrary notwithstanding, the
     Optionee agrees that he will not exercise the Option, and that the Company
     will not be obligated to issue any shares of Common Stock pursuant to this
     Option, if the exercise of the Option or the issuance of such shares shall
     constitute a violation by the Optionee or by the Company of any provisions
     of any law or of any regulation of any governmental authority.  Any
     determination by the Compensation Committee of the Company's board of
     directors (the "Committee") in this connection shall be final, binding and
     conclusive.  The Company shall not be obligated to take any affirmative
     action in order to cause the exercise of the Option or the issuance of
     shares pursuant thereto to comply with such law or regulation.  In this
     connection, the Optionee understands that, unless the issuance of the
     Optioned Shares is registered pursuant to the Securities Act of 1933, as
     amended (the "Securities Act"), the Optioned Shares, if and when issued,
     will be restricted securities, as defined in Rule 144 of the Securities and
     Exchange Commission pursuant to the Securities Act.  The Company shall not
     be required to issue any Optional Shares if the issuance thereof is not
     permitted pursuant to the Securities Act.

10.  Tax Status. In accepting this Option, Optionee understands that in the
     Option is not an incentive stock option, as defined in Section 422 of the
     Internal Revenue Code of 1986, as amended, and Optionee is aware of the tax
     consequences of his exercise of the Option. The Optionee shall pay or
     provide for the payment of any withholding tax due in respect of the
     exercise of this Option.

11.  Action by Company. The existence of the Option shall not effect in any way
     the right or power of the Company or its stockholders to make or authorize
     any or all adjustments, recapitalization, reorganizations or other changes
     in the Company's capital structure or its business, or any merger or
     consolidation of the Company, or any issue of bonds, debentures, preferred
     or prior preference stocks ahead of or affecting the Common Stock or the
     rights thereof, or the dissolution or liquidation of the Company, or any
     sale or transfer of all or any part of its assets or business, or any other
     corporate act or proceeding, whether of a similar character or otherwise.



12.  Interpretation. As a condition of the granting of the Option, the Optionee
     and each person who succeeds to the Optionee's rights pursuant to this
     Instrument of Grant, agrees that any dispute or disagreement which shall
     arise under or as a result of or pursuant to this Option shall be
     determined by the Committee in its sole discretion and that any
     interpretation by the Committee of the terms of this Agreement shall be
     final, binding and conclusive. If no Committee is acting, its functions
     shall be performed by the Board of Directors, and each reference in this
     Option to the Committee shall, in that event, be deemed to refer to the
     Board of Directors.

13.  Notice. Any notice which either party hereto may be required or permitted
     to give to the other shall be in writing, and any be delivered personally
     or by mail, postage prepaid, addressed as follows: to the Company, at 146

     time; to the Optionee, at the address shown at the end of this Agreement,
     or at such other address as the Optionee, by notice to the Company, may
     designate in writing from time to time.

14.  Governing Law. This Agreement shall be construed and governed in accordance
     with the laws of the State of New York without applying its conflict of
     laws principles.

15.  Terms Defined in the Plan. All terms defined in the Plan and used in this
