         AGREEMENT, dated as of April 29, 1999, by and between Robert R.

         WHEREAS, in accordance with the policy of Goldman Sachs, the Grantee is
required to hold the Initial Options and any Additional Option which the Grantee
may receive from time to time as nominee for Goldman Sachs.

         NOW THEREFORE, in consideration of the terms and conditions set forth
herein and other good and valuable consideration, the receipt and adequacy of
which are hereby acknowledged, the parties hereto agree as follows:


         1. Defined Terms. Unless otherwise defined herein, capitalized terms
used herein shall have the meanings given to them in the Plan.

         2. General. The Grantee hereby agree that: (i) the Grantee shall hold
each Option, each share of Stock issuable upon exercise of any Option, and the
proceeds of any sale of any such shares of Stock in trust for the benefit of
Goldman Sachs; (ii) the Grantee shall not (x) exercise the Option, in whole or
in part, (y) Transfer (as defined in Section 2.6) any shares of Stock issuable
upon exercise of the Option, or (z) vote any shares of Stock, except, in each
case, as Goldman Sachs may in its sole discretion direct from time to time; and
(iii) the Grantee shall take all such actions and exercise all such rights and
privileges with respect to any Option or such shares of Stock as Goldman Sachs
may in its sole discretion direct from time to time, provided that the Grantee
shall not be required to take any action or exercise any such rights or
privileges which the Grantee believes, in good faith, would violate any
applicable law or the Grantee's fiduciary duties to the Company. The Grantee
hereby agrees that Goldman Sachs shall be entitled to all such rights and
privileges with respect to any Option or such shares of Stock as if Goldman
Sachs had originally been the grantee under each Option Agreement. Without
limiting the generality of the foregoing, the parties hereto agree as follows:

         a. Exercise of Options. Subject to the exercise schedule set forth in
the applicable Option Agreement, at any time and from time to time that Goldman
Sachs determines to exercise any Option, Goldman Sachs shall provide to the
Grantee written instructions (the "Exercise Instructions") which shall: (i) set
forth the number of shares of Stock in respect of which the Option shall be
exercised (the "Purchased Stock"); (ii) set forth the date on which the
Grantee shall exercise the Option; and (iii) identify the Option to which the
Exercise Instructions relate (such identification to be made by the date of the
Option Agreement or otherwise). The Exercise Instructions may also include such
other instructions as Goldman Sachs may in its sole discretion deem appropriate,
including, without limitation, instructions to the Grantee to: (x) provide to
the Company, to the extent permitted by the applicable Plan

and any committee of the Board of Directors of the Company which administers the
Plan (the "Committee"), irrevocable instructions for a broker to promptly pay to
the Company in full the Option price for the Purchased Stock; or (y) Transfer
(as defined below) the shares of Purchased Stock to, or instruct the Company to
issue such shares of Purchased Stock in the name of, Goldman Sachs or Goldman
Sachs' designee. Upon receipt of the Exercise Instructions, the Grantee shall
exercise the Option referred to therein in accordance with the Exercise
Instructions by delivering written notice to the Company in accordance with the
Exercise Instructions, the applicable Option Agreement and the Plan. Except as
provided in this Section 2, the Grantee shall not exercise any Option.

         b. Exercise Price and Taxes.

         i. Except to the extent Goldman Sachs instructs the Grantee in
accordance with clause (x) of Section 1.1 hereof, Goldman Sachs shall, no later
than the date of exercise specified in the Exercise Instructions, deliver or
cause to be delivered to the Company (on behalf of the Grantee) or deliver or
cause to be delivered to the Grantee (who shall in turn deliver or cause to be
delivered to the Company) cash in an amount equal to the sum of (i) the
aggregate purchase price for the Purchased Stock, and (ii) the amount of any
taxes or other amounts which is imposed by any governmental entity and which the
Grantee is required to satisfy in connection with such exercise. Such payment
may be made by any method permitted pursuant to the Plan or such other method as
the Committee may approve.

         ii. Goldman Sachs shall promptly deliver to the Grantee or otherwise
pay on behalf of the Grantee, any stock transfer or similar taxes payable by the
Grantee in connection with any Transfer requested by Goldman Sachs.

         c. Tax Returns.

         ii. The Grantee will request that the Company (if the Company
determines that it is permissible under applicable law) issue a Form 1099 to
Goldman Sachs rather than to the Grantee in connection with any exercise of any
Option.

         ii. If the Company issues a Form 1099 to the Grantee in connection with
any exercise of any Option in any year, the Grantee shall promptly notify
Goldman Sachs of his receipt of a Form 1099 and, unless the Grantee and Goldman
Sachs otherwise agree in writing, the Grantee shall (i) issue a Form 1099 to
Goldman Sachs to reflect the amount reported in the Form 1099 issued by the
Company, and (ii) attach a statement to his federal income tax return to explain
that the amounts reported in the Company's Form 1099 were received by the
Grantee solely as an agent for Goldman Sachs and are not gross income of the
Grantee. Goldman Sachs shall reimburse the Grantee for up to $1,000 of the


                                      -38-

reasonable costs incurred by the Grantee for tax return preparation for such
year.

         iii. If in any year the Grantee, upon the written instructions of
Goldman Sachs, Transfers any Option or any shares of Stock issued upon the
exercise of any Option in a taxable transaction, Goldman Sachs shall reimburse
the Grantee for up to $1,000 of the reasonable costs incurred by the Grantee for
tax return preparation for such year.

         iv. In the event the Grantee is requested to pay an amount of
additional income tax as a result of the exercise of any Option or any Transfer
requested by Goldman Sachs (the "Incremental Taxes"), the Grantee shall promptly
notify Goldman Sachs and cause his tax accountant or other tax preparer to
prepare a certificate (the "Tax Certificate") setting forth (i) the amount of
Incremental Taxes and (ii) the determination thereof in reasonable detail. The
Tax Certificate shall be provided within 30 days of the receipt by the Grantee
of correspondence from any tax authority with respect to an amount that could
give rise to an Incremental Tax. Goldman Sachs shall have 20 days to review the
Tax Certificate and (A) shall undertake to arrange for the Grantee's defense in
any controversy arising with respect to any Incremental Tax or (B) if the
Grantee has fulfilled all of his obligations hereunder, shall pay to the Grantee
the amount of any Incremental Tax finally determined in accordance with Section
2.3(e) or (f) below. Grantee will cooperate with Goldman Sachs and with any tax
representative selected by Goldman Sachs, which representative shall be
reasonably acceptable to the Grantee, and such cooperation shall include
complying with reasonable requests to furnish information or execute documents
necessary to defend the Grantee in the course of the dispute or to effect a
settlement of the dispute. In the event Goldman Sachs chooses to exercise
alternative (A) above, the costs of defense shall be borne by Goldman Sachs.
Goldman Sachs and the Grantee shall resolve any dispute between them in good
faith.

         v. If Goldman Sachs chooses to pay the Incremental Taxes under Section
2.3(d)(B) hereof, Goldman Sachs shall, within five days after the end of the
20-day review period if there is no dispute or, if there is a dispute, within
five days after the dispute is resolved, pay to the Grantee (i) the amount of
any Incremental Taxes as reflected on the Tax Certificate if there is no dispute
or as the parties may agree if there is a dispute resolved by the parties, and
(ii) an amount necessary to compensate the Grantee for the additional federal,
state or local income or payroll taxes, if any, imposed on the Grantee as a
consequence of Goldman Sachs' payment of the Incremental Taxes and the payment
of any amounts under this subclause (ii) to the Grantee (the "Gross-up Amount").
The Gross-up Amount shall be computed by Goldman Sachs using the highest

                                      -39-

combined effective rate of federal, state and local income tax applicable to a
resident of The City of New York in the taxable year in which Goldman Sachs pays
the Incremental Tax to the Grantee.

         vi. If Goldman Sachs chooses to defend the Grantee with respect to an
Incremental Tax pursuant to Section 2.3(d)(A) hereof, and (i) the Grantee is
assessed an income tax after Goldman Sachs has exhausted all administrative or
other legal remedies that, in its sole discretion, Goldman Sachs chooses to
pursue, or (ii) a settlement is reached, Goldman Sachs shall pay any additional
income tax with respect to such controversy for which the Grantee ultimately is
liable, including a gross-up amount, such amounts to be determined and paid in
accordance with the procedures for determining an Incremental Tax and the
Gross-up Amount in Section 2.3(e) hereof.

         d. Notices; Information. The grantee shall promptly provide to Goldman
Sachs a copy of (i) all written notices delivered to the Grantee as a
