                         UNDER THE AMENDED AND RESTATED
                       ALLIANCE PARTNERS COMPENSATION PLAN

        You have been granted restricted Units under the Amended and Restated
Alliance Partners Compensation Plan (the "Plan"), as specified below, in
connection with your 1999 award under the Plan:

        Participant ("you"): Alfred Harrison

        Amount of Award (to be

        Date of Grant:    December 31, 1999

        Vesting Commencement Date:    January 31, 2000

        In connection with your grant of restricted Units, you, Alliance Capital
Management Holding L.P. and Alliance Capital Management L.P. ("Alliance") agree
as set forth in this agreement (the "Agreement"). The Plan provides a
description of the terms and conditions governing restricted Units. If there is
any inconsistency between the terms of this Agreement and the terms of the Plan,
the Plan's terms completely supersede and replace the conflicting terms of this
Agreement. All capitalized terms have the meanings given them in the Plan,
unless specifically stated otherwise in the Agreement. The restricted Units
granted under this Agreement are referred to in the Agreement as the "Restricted
Units."

        1.     Restrictions.  Until restrictions lapse as described in
Paragraph 2, you may not sell, transfer, pledge or otherwise assign or dispose
of any Restricted Units.

        2. Vesting of Restricted Units. (a) Except as provided in Paragraph 2(b)
below, restrictions will lapse with respect to the Restricted Units in equal
annual installments during the applicable Vesting Period (as defined below),
with restrictions as to the first such installment lapsing on the first
anniversary of the Vesting Commencement Date set forth above, and restrictions
as to the remaining installments lapsing on the subsequent anniversaries of the
Vesting Commencement Date, provided in each case that you are employed by a
Company on such anniversary. The Vesting Period is as set forth in the following
table, based on your age as of December 31, 1999:

               (b) If your employment with the Companies terminates due to death
        or Disability, restrictions on any remaining Restricted Units that you
        hold as of the date of your termination shall immediately lapse.

        3. Forfeitures. If your employment with the Companies terminates for
reasons other than death or Disability, you will immediately forfeit all of your
rights and interests in any Restricted Units as to which restrictions have not
previously lapsed, unless the Committee determines, in its sole discretion, to
accelerate the vesting of those Restricted Units.

        4. Unit Certificates. Your Restricted Units will be held for you by
Alliance. After your Restricted Units have vested, a certificate for those Units
will be released to you.

        5. Distributions. Any distributions paid by Alliance Capital Management
Holding L. P. in connection with Restricted Units (whether or not vested) will
be paid directly to you.

        6. Section 83(b) Election. You agree not to make an election under
section 83(b) of the Code with respect to your Restricted Units unless, before
you file the election with the Internal Revenue Service, you (i) notify the
Committee of your intention to file the election, (ii) furnish the Committee
with a copy of the election to be filed and (iii) pay (or make satisfactory
arrangements for paying) the necessary tax withholding amount to Alliance in
accordance with Section 8.

        7. Tax Withholding. If the Committee determines that any federal, state
or local tax or any other charge is required by law to be withheld with respect
to the Restricted Units, the vesting of Restricted Units, or an election under
Section 83(b) of the Code (a "Withholding Amount") then, in the discretion of
the

<PAGE>

Committee, either (a) prior to or contemporaneously with the delivery to you of
Restricted Units, you agree to pay the Withholding Amount to Alliance in cash or
in vested Units that you already own (which are not subject to a pledge or other
security interest), or a combination of cash and such Units, having a total fair
market value equal to the Withholding Amount; (b) Alliance Capital Management
Holding L.P. will retain from any vested Restricted Units to be delivered to you
that number of Units having a fair market value, as determined by the Committee,
equal to the necessary Withholding Amount; or (c) if Restricted Units are
delivered without the payment of the Withholding Amount under either clause (a)
or (b) above, you agree promptly to pay the Withholding Amount to Alliance on at
least seven business days notice from the Committee either in cash or in vested
Units that you already own (which are not subject to a pledge or other security
interest), or a combination of cash and such Units, having a total fair market
value equal to the Withholding Amount. You agree that if you do not pay the
Withholding Amount to Alliance or make satisfactory payment arrangements as
described above, Alliance may withhold any unpaid portion of the Withholding
Amount from any amount otherwise due to you.

        8. Adjustments in Authorized Units. In the event of a partnership
restructuring, extraordinary distribution or similar event, the Committee has
the sole discretion to adjust the number of Restricted Units in accordance with
the Plan.

        9. Administration. It is expressly understood that the Committee is
authorized to administer, construe, and make all determinations necessary or
appropriate to the administration of the Plan and this Agreement, all of which
shall be binding upon you. The Committee is under no obligation to treat you or
your award consistently with the treatment provided for other participants in
the Plan.

        10.    Miscellaneous.

               (a) This Agreement does not confer upon you any right to
continuation of employment by a Company, nor does this Agreement interfere in
any way with a Company's right to terminate your employment at any time.

               (b) This Agreement will be subject to all applicable laws, rules,
and regulations, and to such approvals by any governmental agencies or national
securities exchanges as may be required.

               (c) This Agreement will be governed by, and construed in
accordance with, the laws of the state of New York (without regard to conflict
of law provisions).
