Subject to the express provisions of the Restated 1991 Plan, the Committee shall
have plenary authority, in its discretion, to grant Options and award Restricted
Shares under the Restated 1991 Plan and to determine the terms and conditions
(which need not be identical), of all Options and Restricted Shares granted or
awarded under the Restated 1991 Plan, including, without limitation, (i) the

available for awards of Restricted Shares under the Restated 1991 Plan to all
individuals in any given fiscal year of the Company shall not exceed 100,000 in

the Restated 1991 Plan, the Committee may take into account the nature of the
services rendered by the respective employees, their present and potential
contributions to the success of the Company its Subsidiaries and such other
factors as the Committee in its discretion shall deem relevant. Subject to the
express provisions of the Restated 1991 Plan, the Committee shall have plenary

the rules and regulations relating to it and to make all other determinations
deemed necessary or advisable for the administration of the Restated 1991 Plan.

deem advisable. A majority of its members shall constitute a quorum and all
determinations shall be made by a majority of such quorum. Any determination
reduced to writing and signed by a majority of the


                                      - 4 -


members shall be fully as effective as if it had been made by a majority vote at
a meeting duly called and held.

     Options and Restricted Shares may be awarded only to salaried employees

(whether or not on a full-time basis) by the Company or a Subsidiary. A director
of the Company or any Subsidiary who is not an officer or employee of the
Company or of one of its Subsidiaries will not be eligible to receive any Awards
under the Restated 1991 Plan. No ISO shall be granted to any employee who, at
the time the ISO is granted, owns (or is considered as owning within the meaning
of Section 424(d), or any successor Section, of the Code) stock possessing more
than 10% of the total combined voting power of all classes of stock of the
Company or of any Subsidiary, unless at the time the ISO is granted the option
price is at least 110% of the Fair Market Value of the Common Stock subject to
the ISO and the ISO by its terms is not exercisable after the expiration of five
years from the date it is granted. Awards may be made to employees who hold or
have held Options and/or Restricted Shares under the Restated 1991 Plan or any
other plans of the Company. An employee who has received Awards under the
Restated 1991 Plan may be granted additional Options and Restricted Shares under
the Restated 1991 Plan or any other plan.

6.   OPTIONS.

     A. OPTION PRICES. Except as otherwise specially provided in paragraph 5
hereof, the purchase price of the Common Stock under each Option shall be
determined by the Committee; PROVIDED, HOWEVER, that the purchase price of the
Common Stock under each Option with respect to Options granted under the
Restated 1991 Plan shall not be less than 100% of the Fair Market Value of the
Common Stock at the time of the granting of such Option.

     B. TERM OF OPTIONS. The term of each Option shall be for such period as the
Committee shall determine, but not more than ten years from the date of grant
and, except as set forth in the applicable Stock Option Agreement, shall expire
upon termination of employment with the Company or any Subsidiary.

     C. EXERCISE OF OPTIONS. Unless otherwise provided herein or in the Stock
Option Agreement, an Option granted under the Restated 1991 Plan shall be
exercisable in whole or in part, at any time during the term of the Option as
provided in a Holder's Stock Option Agreement. Payment shall be made in cash or,
unless otherwise provided in the Stock Option Agreement, in whole shares of
Common Stock or partly in cash and partly in such Common Stock. An Option shall
be exercised by written notice to the Company. Such notice shall state that the
Holder of the Option elects to exercise the Option, the number of shares in
respect of which it is being exercised and the manner of payment for such
shares, and shall either (i) be accompanied by payment of the full purchase
price of such shares or (ii) fix a date (not more than 10 business days from the
date of exercise) for the payment of the full purchase price of such shares.
Cash payments shall be made by wire transfer, certified or bank check or
personal check, in each case payable to the order of the Company; PROVIDED,
HOWEVER, that the Company shall not be required to deliver certificates for
shares with respect to which an Option is


                                      - 5 -


exercised until the Company has confirmed the receipt of good and available
funds in payment of the purchase price thereof. Common Stock payments may be
made either through the surrender of previously held shares of Common Stock (by
delivery of stock certificates in negotiable form) or the withholding of shares
of Common Stock otherwise issuable upon the exercise of the subject Options
having a Fair Market Value equal to such exercise price, but in each case only
to the extent the Holder has owned for at least six months prior to exercise a
sufficient number of shares of Common Stock valued by the Fair Market Value of
such Common Stock on the date of exercise to cover such exercise price;
PROVIDED, HOWEVER, that the election of a Holder, whose transactions are subject
to Section 16(b) of the Exchange Act, to make a Common Stock payment (whether by
surrender or withholding) shall be subject to and must comply with Rule 16b-3(e)
as promulgated by the SEC under the Exchange Act, or any successor regulation
adopted by the SEC. Common Stock payments shall be valued at the Fair Market
Value of a share of Common Stock on the date of exercise. Except as specifically
provided in the applicable Stock Option Agreement, no Option may be exercised at
any time unless the Holder thereof is then an employee of the Company or of a
Subsidiary. The Holder of an Option shall have none of the rights of a
stockholder with respect to the shares subject to the Option until such shares
shall be transferred to the Holder upon the exercise of the Option.

     D. ISOS. Notwithstanding anything to the contrary contained herein, but
subject to paragraph 8 hereof, in the case of ISOs, the aggregate Fair Market
Value (determined at the time the Option is granted) of the shares of Common
Stock covered by ISOs which first become exercisable in any calendar year under
the Restated 1991 Plan by any individual employee (and under all other plans of
the Company or any Subsidiary which provide for the granting of ISOs) shall not
exceed $100,000.

     E. SARS. The Committee may (but shall not be obligated to) grant SARs
pursuant to the provisions of this subparagraph 6E to the Holder of any Option
granted under the Restated 1991 Plan (hereinafter in this subparagraph 6E called
a "related Option") with respect to all or a portion of the shares subject to
the related Option. An SAR may be granted concurrently with the grant of the
related Option or subsequently (except that an SAR related to an ISO may only be
granted concurrently). The terms and conditions of such an SAR shall be as
stated in this subparagraph 6E and in the Stock Option Agreement governing the
related Option (hereinafter called the "related Stock Option Agreement").
Subject to the terms and provisions of this subparagraph 6E, each SAR shall be
exercisable only at the same time and to the same extent the related Option is
exercisable, and in no event after the termination or exercise of the related
Option. Notwithstanding the foregoing, no SAR may be exercised within a period
of six months after the date of grant of the SAR. SARs granted under the
Restated 1991 Plan shall be exercisable in whole or in part by notice to the
Company. Such notice shall state that the Holder of the SARs elects to exercise
the SARs, the number of shares in respect of which the SARs are being exercised
and the form of payment the Holder requests.

     Subject to the terms and provisions of this subparagraph 6E and the related
Stock Option Agreement, upon the exercise of SARs, the Holder thereof shall be
entitled to receive from the Company consideration (in the form hereinafter
provided) equal in value to the excess of the Fair Market Value as of the date
of exercise of the SARs of each share of Common Stock with respect to which such
SARs have been exercised over the option price per share of Common


                                      - 6 -


Stock subject to the related Option. Upon the exercise of an SAR, the Holder may
specify the form of consideration to be received by such Holder, which shall be
in shares of Common Stock (valued at the Fair Market Value on the date of
exercise of the SAR), or in cash, or partly in cash and partly in shares of
Common Stock as the Holder shall request; PROVIDED, HOWEVER, that the Committee
in its sole discretion may disapprove the form of consideration requested and
instead authorize the payment of such consideration in shares of Common Stock
(valued as aforesaid), or in cash, or partly in cash and partly in shares of
Common Stock. Any election by the Holder of an SAR to receive cash in full or
partial settlement of the SAR, as well as any exercise of an SAR for such cash,
shall be made only in accordance with the terms and conditions for such election
or exercise stated in the related Stock Option Agreement. Unless otherwise
provided in the related Stock Option Agreement, for purposes of this
subparagraph 6E, the date of exercise of an SAR shall mean the date on which the
Company shall have received notice from the Holder of the SAR of the exercise of
such SAR.

     Upon the exercise of SARs, the related Option shall be considered to have
been exercised to the extent of the number of shares of Common Stock with
respect to which such SARs are exercised, and shall be considered to have been
exercised to that extent for purposes of determining the number of shares of
Common Stock available for the grant of Options under the Restated 1991 Plan.
Upon the exercise or termination of the related Option, the SARs with respect to
such related Option shall be considered to have been exercised or terminated to
the extent of the number of shares of Common Stock with respect to which the
related Option was so exercised or terminated.

     The provisions of paragraphs 4, 6B and 8 through 21 of the Restated 1991
Plan (to the extent that such provisions are applicable to Options) shall also
be applicable to SARs unless the context otherwise requires. The effective date
of the grant of an SAR shall be the date on which the Committee approves the
grant of such SAR. Each grantee of an SAR shall be notified promptly of the
grant of an SAR.

     F. NONTRANSFERABILITY OF OPTIONS. No Option shall be transferable otherwise
than by will or the laws of descent and distribution or pursuant to a qualified
domestic relations order as defined by the Code or Title I of the Employee
Retirement Income Security Act of 1974, as amended from time to time, or the
rules thereunder. An Option may be exercised during the lifetime of the Holder
thereof only by such Holder. A breach by the Holder of any of the restrictions,
terms or conditions provided in the Restated 1991 Plan or in the Holder's Stock
Option Agreement will cause the Options covered thereby to be terminated.

7.   RESTRICTED SHARES.

     A. VALUATION DATE AND PRICE. The committee shall designate a Valuation Date
with respect to each Award of Restricted Shares and may prescribe restrictions,
terms and conditions applicable to the vesting of such Restricted Shares in
addition to those provided in the Restated 1991 Plan. The Committee shall
determine the price, if any, to be paid by the Holder for the Restricted Shares.


                                      - 7 -


     B. ISSUANCE OF RESTRICTED SHARES. Restricted Shares, when issued, will be
represented by a stock certificate or certificates registered in the name of the
Holder to whom such Restricted Shares shall have been awarded. During the
Restriction Period, certificates representing the Restricted Shares and any
securities constituting Retained Distributions shall bear a restrictive legend
to the effect that ownership of the Restricted Shares (and such Retained
Distributions), and the enjoyment of all rights appurtenant thereto, are subject
to the restrictions, terms and conditions provided in the Restated 1991 Plan and
the applicable Restricted Shares Agreement. Such certificates shall be deposited
by such Holder with the Company, together with stock powers or other instruments
of assignment, each endorsed in blank, which will permit transfer to the Company
of all or any portion of the Restricted Shares and any securities constituting
Retained Distributions that shall be forfeited or that shall not become vested
in accordance with the Restated 1991 Plan and the applicable Restricted Shares
Agreement.

     C. RESTRICTIONS. Restricted Shares shall constitute issued and outstanding
shares of Common Stock for all corporate purposes. The Holder will have the
right to vote such Restricted Shares, to receive and retain all regular cash
dividends, and such other distributions as the Committee may in its sole
discretion designate, paid or distributed on such Restricted Shares and to
exercise all other rights, powers and privileges of a Holder of Common Stock
with respect to such Restricted Shares, with the exception that (i) the Holder
will not be entitled to delivery of the stock certificate or certificates
representing such Restricted Shares until the Restriction Period shall have
expired and unless all other vesting requirements with respect thereto shall
have been fulfilled; (ii) the Company will retain custody of the stock
certificate or certificates representing the Restricted Shares during the
Restriction Period; (iii) other than regular cash dividends and such other
distributions as the Committee may in its sole discretion designate, the Company
will retain custody of all distributions ("Retained Distributions") made or
declared with respect to the Restricted Shares (and such Retained Distributions
will be subject to the same restrictions, terms and conditions as are applicable
to the Restricted Shares) until such time, if ever, as the Restricted Shares
with respect to which such Retained Distributions shall have been made, paid or
declared shall have become vested, and such Retained Distributions shall not
bear interest or be segregated in separate accounts, (iv) the Holder may not
sell, assign, transfer, pledge, exchange, encumber or dispose of the Restricted
Shares or any Retained Distributions during the Restriction Period; and (v) a
breach of any restrictions, terms or conditions provided in the Restated 1991
Plan or established by the Committee with respect to any Restricted Shares or
Retained Distributions will cause a forfeiture of such Restricted Shares and any
Retained Distributions with respect thereto.

     D. CASH AWARDS. In connection with any award of Restricted Shares, the
Committee may authorize (either at the time such award is made or subsequently)
the payment of a cash amount (a "Cash Award") to the Holder of such Restricted
Shares at any time after such Restricted Shares shall have become vested;
PROVIDED, HOWEVER, that the amount of the cash payment, if any, that a Holder
shall be entitled to receive shall not exceed 100% of the aggregate Maturity
Value of the Restricted Shares awarded to such Holder hereunder. Such Cash
Awards shall be payable in accordance with such additional restrictions, terms
and conditions as shall be prescribed by the Committee and shall be in addition
to any other salary, incentive, bonus or other compensation payments which
Holders shall be otherwise entitled or eligible to receive from the Company.


                                      - 8 -


     E. COMPLETION OF RESTRICTION PERIOD. On the Valuation Date with respect to
each award of Restricted Shares, and the satisfaction of any other applicable
restrictions, terms and conditions (i) all or part of such Restricted Shares
shall become vested, (ii) any Retained Distributions with respect to such
Restricted Shares shall become vested to the extent that the Restricted Shares
related thereto shall have become vested, and (iii) any Cash Award to be
received by the Holder with respect to such Restricted Shares shall become
payable, all in accordance with the terms of the applicable Restricted Shares
Agreement. Any such Restricted Shares and Retained Distributions that shall not
have become vested shall be forfeited to the Company and the Holder shall not
thereafter have any rights (including dividend and voting rights) with respect
to such Restricted Shares and Retained Distributions that shall have been so
forfeited.

8.   ACCELERATION OF OPTIONS AND RESTRICTED SHARES.

     Notwithstanding any contrary waiting period or installment period in any
Stock Option Agreement or any Restriction Period in any Restricted Shares
Agreement or in the Restated 1991 Plan, each outstanding Option granted under
the Restated 1991 Plan shall, except as otherwise provided in the applicable
Stock Option Agreement, become exercisable in full for the aggregate number of
shares covered thereby, and each Restricted Share, except as otherwise provided
in the Restricted Shares Agreement, shall vest unconditionally, in the event (i)
the Board (or, if approval of the Board is not required as a matter of law, the
stockholders of the Company) shall approve (a) any consolidation or merger of
the Company in which the Company is not the continuing or surviving corporation
or pursuant to which shares of Common Stock would be converted into cash,
securities or other property, other than a Merger, or (b) any sale, lease,
exchange, or other transfer (in one transaction or a series of related
transactions) of all, or substantially all, of the assets of the Company, or (c)
the adoption of any plan or proposal for the liquidation or dissolution of the
Company, or (ii) any person (as such term is defined in Sections 13(d)(3) and
14(d)(2) of the Exchange Act), corporation or other entity (other than the
Company or any employee benefit plan sponsored by the Company or any Subsidiary)
(A) shall purchase any Common Stock of the Company (or securities convertible
into the Company's Common Stock) for cash, securities or any other consideration
pursuant to a tender offer or exchange offer, without the prior consent of the
Board, and (B) shall become the "beneficial owner" (as such term is defined in
Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the
Company representing 20 percent or more of the combined voting power of the then
outstanding securities of the Company ordinarily (and apart from rights accruing
under special circumstances) having the right to vote in the election of
directors (calculated as provided in paragraph (d) of such Rule 13d-3 in the
case of rights to acquire the Company's securities), or (iii) during any period
of two consecutive years, individuals who at the beginning of such period
constitute the entire Board shall cease for any reason to constitute a majority
thereof unless the election, or the nomination for election by the Company's
stockholders, of each new director was approved by a vote of at least two-thirds
of the directors then still in office who were directors at the beginning of the
period, or (iv) there occurs such other transactions involving a significant
issuance of voting stock or change in the composition of the Board that the
Board determines to be an accelerating event under this paragraph 8. Any
transaction referred to in the foregoing clause (i) is herein called an Approved
Transaction, any purchase pursuant to a tender offer or


                                      - 9 -


exchange offer or otherwise as described in the foregoing clause (ii) is herein
called a Control Purchase, the cessation of individuals constituting a majority
of the Board as described in the foregoing clause (iii) is herein called a Board
Change and such other transactions as described in the foregoing clause (iv) is
herein called an "Other Accelerating Event". The Stock Option Agreement and
Restricted Shares Agreement evidencing Options or Restricted Shares granted
under the Restated 1991 Plan may contain such provisions limiting the
acceleration of the exercisability of Options and the acceleration of the
vesting of Restricted Shares as provided in this paragraph 8 as the Committee
deems appropriate to ensure that the penalty provisions of Section 4999 of the
Code, or any successor thereto in effect at the time of such acceleration, will
not apply to any stock, cash or other property received by the Holder from the
Company.

9.   TERMINATION OF EMPLOYMENT.

     A. OPTION EXERCISABILITY AFTER TERMINATION. An Option shall be exercisable
after termination of the Holder's employment in accordance with the terms and
conditions of the applicable Stock Option Agreement; PROVIDED, HOWEVER, that the
exercise of an Option after the termination of employment of the Holder for any
reason is subject to the following: (i) no Option may be exercised after the
expiration date of such Option, and (ii) subject to subparagraph 9B hereof, only
Options exercisable by the Holder at the time of the Holder's termination of
employment may be exercised after such termination.

     B. CERTAIN TERMINATIONS-ACCELERATION OF EXERCISABILITY OR VESTING.
Notwithstanding any provisions to the contrary in the applicable Restricted
Shares Agreement or Stock Option Agreement, if the Holder's employment shall
have been terminated for any reason (including, without limitation, the Holder's
death, Total Disability, retirement (either pursuant to any retirement plan of
the Company or any Subsidiary or, in the absence of any such plan, pursuant to
the Committee's Discretionary determination that such termination of employment
shall be treated as retirement for purposes of this Restated 1991 Plan),
resignation or voluntary termination or it the Holder's employment shall have
been terminated by the Company or the employing Subsidiary without "Cause", as
defined in subparagraph 9C hereof) other than a termination by the Company or
the employing Subsidiary for "Cause", as defined in subparagraph 9C hereof, in
the Committee's sole discretion, exercisable either before or after the
termination of a Holder's employment, the Committee may determine the following:

          (i) Any Restriction Period applicable to any Award of Restriction
     Shares held by the Holder shall be deemed to have expired upon the Holder's
     termination of employment, and all such Restricted Shares and Retained
     Distributions thereon shall become vested, and any Cash Award payable
     pursuant to the applicable Restricted Shares Agreement shall be adjusted in
     such manner as is provided in the Restricted Shares Agreement; and/or

          (ii) Any Option held by the Holder shall become exercisable in full
     upon the Holder's termination of employment.

     C. TERMINATION BY COMPANY FOR CAUSE. If a Holder's employment with the
Company or any Subsidiary shall be terminated by the Company or such Subsidiary
during the


                                     - 10 -



Restriction Period, with respect to any Restricted Shares, or prior to the
exercise of any Option for "Cause" (for these purposes, "Cause" shall have the
meaning ascribed thereto in any employment agreement to which such Holder is a
party or, in the absence thereof, shall include, but no be limited to,
insubordination, dishonesty, incompetence, moral turpitude, other misconduct of
any kind and the refusal to perform his or her duties and responsibilities for
any reason other than illness or incapacity; PROVIDED, HOWEVER, that if such
termination occurs within 12 months after an Approved Transaction, Control
Purchase, Board Change or Other Accelerating Event, termination for Cause shall
only mean a felony conviction for fraud, misappropriation or embezzlement), then
upon the termination of employment:

          (i)  All Options held by such Holder shall immediately terminate; and

          (ii) Such Holder's rights to all Restricted Shares, Retained
     Distributions and any Cash Awards shall be forfeited immediately.

     D. GENERAL. For purposes of the Restated 1991 Plan, a leave of absence,
unless otherwise determined by the Committee prior to the commencement thereof,
shall not be considered a termination of employment. Awards made under this
Restated 1991 Plan shall not be affected by any change of employment so long as
the Holder continues to be an employee of the Company or a Subsidiary.

10.  RIGHT OF COMPANY TO TERMINATE EMPLOYMENT.

     Nothing contained in the Restated 1991 Plan or in any Award (or instrument
evidencing any Award) shall confer on any Holder any right to continue in the
employ of the Company or any of its Subsidiaries or interfere in any way with
the right of the Company or a Subsidiary to terminate the employment of the
Holder at any time, with or without cause.

11.  NONALIENATION OF BENEFITS.

     No right or benefit under the Restated 1991 Plan shall be subject to
anticipation, alienation, sale, assignment, hypothecation, pledge, exchange,
transfer, encumbrance or charge, and any attempt to anticipate, sell, assign,
hypothecate, pledge, exchange, transfer, encumber or charge the same shall be
void. No right or benefit hereunder shall in any manner be liable for or subject
to the debts, contracts, liabilities or torts of the person entitled to such
benefit.

12.  WRITTEN AGREEMENT.

         Each award of Restricted Shares and any right to a Cash Award hereunder
shall be evidenced by a Restricted Shares Agreement and each grant of an Option
(and any related SAR) shall be evidenced by a Stock Option Agreement, each in
such form and containing such terms and provisions not inconsistent with
provisions of the Restated 1991 Plan as the Committee from time to time shall
approve. The effective date of the granting of an Option shall be the date on
which the Committee approves the granting of such Option. Each grantee of an
Option or Restricted Share shall be notified promptly of such grant and a
written Stock Option Agreement and/or Restricted Shares Agreement shall be
promptly executed and delivered by the Company


                                     - 11 -


and the grantee, provided that such grant of Options or Restricted Shares shall
terminate if such written agreement is not signed by such grantee (or his or her
attorney) and delivered to the Company within 60 days after the date the
Committee approved such grant. Any such written agreement can be amended by the
Committee from time to time, with the Holder's consent. Any such written
agreement may contain such provisions as the Committee deems appropriate to
ensure that the penalty provisions of Section 4999 of the Code, or any successor
thereto, will not apply to any stock or cash received by the Holder from the
Company.

13.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.

     In the event of changes in the outstanding Common Stock of the Company by
reason of any stock dividend, distribution, split-up, recapitalization,
combination or exchange of shares, merger, consolidation or liquidation and the
like, the Committee shall adjust the aggregate number and class of shares
available under the Restated 1991 Plan and shall provide for an equitable
adjustment of any outstanding Award, which adjustment shall be conclusive.

     The grant of an Award pursuant to the Restated 1991 Plan shall not affect,
in any way, the right or power of the Company to make adjustments,
reclassifications, reorganizations or changes to its capital or business
structure or to merge or to consolidate or to dissolve, liquidate or sell, or
transfer all or any part of its business or assets.

14.  TERMINATION AND AMENDMENT.

     No Awards may be made under the Restated 1991 Plan after June 30, 2001, or
such earlier date as of which the Restated 1991 Plan may have been terminated,
as hereinafter provided. The Board may at any time prior to June 30, 2001
terminate the Restated 1991 Plan, and the Board may at any time also modify or
amend the Restated 1991 Plan in such respects as it shall deem advisable;
PROVIDED, HOWEVER, that the Board may not, without approval of the Holders of a
majority of the voting securities of the Company present, either in person or by
proxy, and entitled to vote at a meeting (i) materially increase (except as
provided in paragraph 13 hereof) the maximum number of shares which may be
issued under the Restated 1991 Plan, (ii) materially modify the requirements as
to eligibility for participation in the Restated 1991 Plan, or (iii) materially
increase the benefits accruing to participants under the Restated 1991 Plan. No
termination, modification or amendment of the Restated 1991 Plan or any
outstanding Restricted Shares Agreement or Stock Option Agreement may, without
the consent of the employee to whom any Award shall theretofore have been
granted, adversely affect the rights of such employee with respect to such
Award.

15.  EFFECTIVENESS OF THE RESTATED 1991 PLAN.

     The Restated 1991 Plan (which amends and restates the 1991 Plan) shall
become effective as of the date of the Company's 1994 Annual Meeting of
Stockholders upon approval by the vote of a majority of the voting securities of
the Company present, either in person or by proxy, and entitled to vote at the
Company's 1994 Annual Meeting of Stockholders. Prior to such approval, the
Committee may, in its discretion, grant Awards under the Restated 1991 Plan
provided that the exercise of Options so granted and the vesting of Restricted
Shares so granted


                                     - 12 -


shall be expressly subject to the condition that the Restated 1991 Plan shall
have been so approved. Unless the Restated 1991 Plan shall be so approved, the
Restated 1991 Plan and all Awards theretofore made thereunder shall be and
become null and void, and all Awards made under the 1991 Plan shall continue to
be governed by the terms and provisions of the 1991 Plan.

16.  GOVERNMENT AND OTHER REGULATIONS.

     The obligation of the Company with respect to Awards shall be subject to
(i) all applicable laws, rules and regulations and such approvals by any
governmental agencies as may be required, including, without limitation, the
effectiveness of a registration statement under the Securities Act of 1933, and
(ii) the rules and regulations of any securities exchange on which the Common
Stock may be listed.

17.  WITHHOLDING.

     The Company's obligation to deliver shares of Common Stock or to pay cash
upon the exercise of any Nonqualified Stock Option or any SAR granted under the
Restated 1991 Plan and to deliver stock certificates or to pay cash upon the
vesting of Restricted Shares or Cash Awards shall be subject to applicable
Federal, state and local (including income, FICA and other) tax withholding
requirements. Federal, state and local withholding (including income, FICA and
other) tax due upon the exercise of any Nonqualified Stock Option and upon the
vesting of Restricted Shares may be paid in shares of Common Stock (either
through the surrender of previously held shares of Common Stock or the
withholding of shares of Common Stock otherwise issuable upon the exercise of
such Award) having a Fair Market Value equal to the required withholding and
upon such other terms and conditions as the Committee shall determine, but with
respect to withholding amounts in excess of the minimum statutory requirements
only to the extent the Holder has owned for at least six months prior to
exercise a sufficient number of shares of Common Stock valued by the Fair Market
Value of such Common Stock on the date of exercise to cover such withholding
amount in addition to any shares required to cover the exercise price pursuant
to subparagraph 6C above; PROVIDED, HOWEVER, that the Committee, in its sole
discretion, may disapprove such payment and require that such taxes be paid in
cash; and PROVIDED, FURTHER, that the election by a Holder, whose transactions
in Common Stock are subject to Section 16(b) of the Exchange Act, to pay in
shares of Common Stock (whether by surrender or withholding) shall be subject to
and must comply with Rule 16b-3(e) as promulgated by the SEC under the Exchange
Act, or any successor regulation adopted by the SEC.

18.  SEPARABILITY.

     If any of the terms or provisions of the Restated 1991 Plan conflict with
the requirements of Rule 16b-3 under the Exchange Act (as the same shall be
amended from time to time) and/or, with respect to ISOs, Section 422 of the Code
(as the same shall be amended from time to time), then such terms or provisions
shall be deemed inoperative to the extent they so conflict with the requirements
of said Rule 16b-3, and/or with respect to ISOs, Section 422 of the Code.


                                     - 13 -



     With respect to ISOs, if the Restated 1991 Plan does not contain any
provision required to be included herein under Section 422 of the Code (as the
same shall be amended from time to time), such provision shall be deemed to be
incorporated herein with the same force and effect as if such provision had been
set out at length herein.

19.  NON-EXCLUSIVITY OF THE RESTATED 1991 PLAN.

     Neither the adoption of the Restated 1991 Plan by the Board nor the
submission of the Restated 1991 Plan to the stockholders of the Company for
approval shall be construed as creating any limitations on the power of the
Board to adopt such other incentive arrangements as it may deem desirable,
including, without limitation, the granting of stock options and the awarding of
stock and cash otherwise than under the Restated 1991 Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.

20.  EXCLUSION FROM PENSION AND PROFIT-SHARING COMPUTATION.

     By acceptance of an Award, each Holder shall be deemed to have agreed that
the award of Restricted Shares and any right to a Cash Award and the grant of
any Option and the exercise thereof or of any SAR are special incentive
compensation and that they will not be taken into account as "salary" or
"compensation" or "bonus" in determining the amount of any payment under any
pension, retirement or other qualified employee benefit plan of the Company or
any Subsidiary. In addition, each beneficiary of a deceased Holder shall be
deemed to have agreed that such Award will not affect the amount of any life
insurance coverage provided by the Company on the life of the Holder which is
payable to such beneficiary under any life insurance plan covering employees of
the Company or any Subsidiary.

21.  GOVERNING LAW.

     The Restated 1991 Plan shall be governed by, and construed in accordance
with, the laws of the State of Delaware.
