that certain Amended and Restated 1993 Stock Option Plan adopted by the
Company's Board of Directors (the "Plan") and approved by its shareholders, and
in consideration of the services to be rendered to the Company or its
subsidiaries by Gary A. Shiffman ("Employee"), hereby grants and issues, as of
May 10, 2004 (the "Date of Grant"), to Employee seventy-five thousand (75,000)
shares of the Company's Common Stock, par value $0.01 per share (the "Shares"),
subject to the terms and conditions contained in this Restricted Stock Award
Agreement (the "Agreement") and subject to all the terms and conditions of the
Plan, which are incorporated by reference herein. Employee agrees to the
provisions set forth herein and in the Plan and acknowledges that each such
provision is a material condition of the Company's agreement to issue the Shares
to him. All capitalized terms used but not otherwise defined in this Agreement
shall have the meanings ascribed to such terms in the Plan.

                        I. RECEIPT AND DELIVERY OF SHARES

      Until such time as the Shares vest in accordance with Section II below,
the stock certificate or certificates evidencing the Shares shall be registered
in the name of Employee but held in escrow by the Company. As soon as
practicable after the date upon which any Shares vest, the Company shall deliver
to Employee a certificate or certificates representing such vested Shares,
registered in the name of Employee.

the restrictions and conditions set forth in the Plan, the remaining 56,250
Shares (the "Performance-Vesting Shares") shall vest on March 1, 2010 (provided
that Employee is employed by the Company on such date) on the basis of the

(as determined by reference to the Company's audited financial statements) (the

any reason other than the death or Disability (as defined below) of Employee,
all unvested Shares shall be automatically forfeited to the Company and,
accordingly, Employee shall forfeit all right, title and interest in and to such
forfeited Shares. For purposes hereof, "Disability" shall mean physical or
mental incapacity for an aggregate period of at least 90 days within any period
of 365 consecutive days.

      (d) Notwithstanding anything to the contrary herein, upon the death or
Disability of Employee, all unvested Time-Vesting Shares shall immediately
become fully vested and not forfeitable and a pro-rata portion of the
Performance-Vesting Shares ultimately earned in accordance with Section II(a),
determined on the basis of the ratio of the number of months that Employee was
employed during the period from January 1, 2004 through December 31, 2009 (the
"Performance Period") to the total number of months in the Performance Period,
shall become vested and not forfeitable on March 1, 2010. Notwithstanding
anything to the contrary herein, upon the occurrence of a Change of Control
Event, all unvested Shares shall immediately become fully vested and not
forfeitable.

                           III. RESTRICTIONS ON SHARES

      Until a Share vests pursuant to Section II above, it shall not be liable
for the debts, contracts or obligations of Employee nor be subject to
disposition by assignment, transfer, sale, alienation, pledge, encumbrance or
any other means, whether such disposition is voluntary or involuntary or by
operation of law by judgment, levy, attachment, garnishment or other legal or
equitable proceeding (including bankruptcy), and any attempted disposition
thereof shall be null and void and of no force or effect; provided, however,
that this Section III does not prevent transfers by will or by the applicable
laws of descent and distribution, or pursuant to the terms of a Qualified
Domestic Relations Order.

                           IV. RIGHTS AS A STOCKHOLDER

      Notwithstanding Section 9.06 of the Plan to the contrary, Employee shall
be entitled to all of the rights of a stockholder with respect to the
Time-Vesting Shares, including the right to vote such Time-Vesting Shares and to
receive dividends and other distributions payable with respect to such
Time-Vesting Shares from and after the Date of Grant; provided that any
securities or other property (but not cash) received in any such distribution
with respect to any Time-Vesting Shares that are still subject to the
restrictions of Section II and III of this Agreement shall be subject to all of
the restrictions in this Agreement with respect to such Time-Vesting Shares.
Notwithstanding anything to the contrary herein, Employee shall not be entitled
to any of the rights of a stockholder with respect to the Performance-Vesting
Shares until such Performance-Vesting Shares vest in accordance with Section II
of this Agreement.

                                 V. REGISTRATION

      Subject to the other terms and conditions of this Agreement, the Shares
may be offered and sold by Employee only if such stock is registered for resale
under the Securities Act of 1933, as amended (the "Securities Act"), or if an
exemption from registration under the Securities Act is available. Employee
acknowledges and agrees: (a) that the Company has no obligation to effect such
registration; (b) not to offer or sell the Shares unless and until such stock is
registered for resale under the Securities Act or an exemption from registration
is available; and (c) that the Shares were acquired for his own account for
investment and not with a view to, or for sale in connection with, the
distribution of any part thereof.

                      VI. NO RIGHT TO EMPLOYMENT CONFERRED

      Nothing in this Agreement or the Plan shall confer upon Employee any right
to continue in employment with the Company or a subsidiary or interfere in any
way with the right of the Company or any subsidiary to terminate such person's
employment at any time.

                               VII. MISCELLANEOUS

      (a) In accordance with the terms of the Plan, the Company is entitled to
withhold (or secure payment from Employee in lieu of withholding) the amount of
any withholding or other tax required by law to be withheld or paid by the
Company with respect to the award or issuance of the Shares. Employee
understands that the taxable income recognized by Employee as a result of the
award of the Shares would be affected by a decision by Employee to make an
election under Section 83(b) of the Internal Revenue Code of 1986, as amended
(the "83(b) Election"), with respect to the Shares within thirty (30) days after
the Date of Grant. Employee acknowledges and agrees that he will have the sole
responsibility for determining whether to make an 83(b) Election with respect to
the Shares and for properly making such election and filing such election with
the relevant taxing authorities on a timely basis.

      (b) If any provision of this Agreement is held invalid or unenforceable,
the remaining provisions shall continue to be in full force and effect to the
maximum extent permitted by law. If the implementation or presence of any
provision of this Agreement would or will cause the Plan and thereby the Shares
purchased thereunder to not be in compliance with Rule 16b-3 under the
Securities Exchange Act of 1934, as amended, or any other statutory provision,
such Agreement provision shall not be implemented or, at the Company's option
following notice, such provision shall be severed from the Agreement as is
appropriate or necessary to achieve statutory compliance; provided, however,
that the parties hereby agree to negotiate in good faith as may be necessary to
modify this Agreement to achieve statutory compliance or otherwise effectuate
the intent of the parties following a severance permitted by this Section
VII(b).

      (c) The number and kind of Shares, Time-Vesting Shares and
Performance-Vesting Shares shall be appropriately adjusted to reflect any stock
dividend, stock split, combination or exchange of shares, or other change in
capitalization with a similar substantive effect upon such Shares. The
Administrator shall have the power to determine the amount of the adjustment to
be made in each case.

                                       -3-

Road, Suite 200, Southfield, Michigan 48034, and any notice required to be given
to Employee shall be sent to Employee's address as shown on the records of the
Company.

      (e) This instrument contains the entire Agreement of the parties and may
only be amended by written agreement executed by the parties hereto.

      (f) This Agreement is made and entered into in, and shall be construed and
enforced in accordance with the laws of, the State of Michigan.

      IN WITNESS WHEREOF, this Restricted Stock Award Agreement is hereby
executed as of May 10, 2004.
