               Corporation, the Committee may, upon the Participant's request
               and in the Committee's sole discretion, waive or revise this

          other rights of a shareholder of the Corporation with respect to the

all applicable stock certificates to the Corporation.


6.   COVENANTS

     (a)  The Participant agrees to be bound by all terms and provisions of the
          Plan, and all such provisions shall be deemed a part of this Agreement
          for all purposes.

     (b)  The Participant agrees to provide the Corporation, when and if
          requested, with any information or documentation which the Corporation
          believes necessary or advisable in connection with the administration
          of the Plan, including data required to assure compliance with the
          requirements of the Securities and Exchange Commission, of any stock
          exchange upon which the Huttig Shares are then listed, or of any
          applicable federal, state or other law.

     (c)  The Participant agrees, upon due notice and demand, to promptly pay to
          the Corporation the cash amount of any taxes which are required to be

          elects to be taxed at such earlier time); provided, however, the
          Corporation, in its sole discretion, may accept Restricted Stock
          awarded hereunder or Huttig Shares otherwise previously acquired in
          satisfaction thereof.

7.   NO COVENANT OF EMPLOYMENT

     Neither the execution and delivery of this Agreement nor the granting of
any award evidenced by this Agreement shall constitute, or be evidence of, any
agreement or understanding, express or implied, on the part of the Corporation
or any of its subsidiaries to employ the Participant for any specific period.

8.   ADMINISTRATION AND INTERPRETATION OF PLAN AND AGREEMENT

     In the event of any conflict between the terms of this Agreement and those

     The Committee shall have full authority and discretion, subject only to the
terms of the Plan, to decide all matters relating to the administration or
interpretation of the Plan and this Agreement, and all such action by the
Committee shall be final, conclusive, and binding upon the Corporation and the
Participant. The Committee shall have full authority and discretion to modify at
any time the Restriction Period, the Restrictions, the other terms and
conditions of this Agreement, the Legend and any other instrument evidencing
this award, provided that no such modification shall increase the benefit under
such award beyond that which the Committee could have originally granted at the
time of the award, or shall impair the rights of the Participant under such
award except in accordance with the Plan, or any applicable agreement or
applicable law, or with consent of the Participant.

     This Restricted Stock Agreement is deemed to be issued in, the award
evidenced hereby is deemed to be granted in, and both shall be governed by the
laws of, the State of Delaware. There have been no representations to the
Participant other than those contained herein.

9.   DELIVERY

deem advisable under the rules, regulations, and other requirements of the
Securities and Exchange Commission, any stock exchange upon which Huttig Shares
are then listed and any applicable federal or state securities law, and the
Committee may cause a legend or legends to be put on any such certificates to
make appropriate reference to such restrictions.

     The stock certificates evidencing the Restricted Stock shall be held in
custody by the Corporation or its designee until the Restrictions thereon shall
have lapsed and the Committee may require, as a condition of any award, that the
Participant shall have delivered a stock power endorsed in blank relating to the
Restricted Stock covered by such award.

     As soon as administratively practicable following the lapse of the
Restrictions with respect to any of the Restricted Stock without a forfeiture,
and upon the satisfaction of all other applicable conditions as to the
Restricted Stock, including, but not limited to, the payment by the Participant
of all applicable withholding taxes, the Corporation shall deliver or cause to

Restricted Stock which shall not bear the Legend required under Section 4 of the
Agreement.
