                               POWERS OF THE COMMITTEE

     4.1   Power to Grant.  The Committee shall determine the Participants to
whom Awards shall be granted, the type or types of Awards to be granted, and the
terms and conditions of any and all such Awards. The Committee may establish
different terms and conditions for different types of Awards, for different
Participants receiving the same type of Awards, and for the same Participant for
each Award such Participant may receive, whether or not granted at different
times.

     4.2   Administration.  The Committee shall be responsible for the
administration of the Plan. The Committee, by majority action thereof, is
authorized to prescribe, amend, and rescind rules and regulations relating to
the Plan, to provide for conditions deemed necessary or advisable to protect the
interests of the Company, and to make all other determinations necessary or
advisable for the administration and interpretation of the Plan in order to
carry out its provisions and purposes. Determinations, interpretations, or other
actions made or taken by the Committee pursuant to the provisions of the Plan
shall be final, binding, and conclusive for all purposes and upon all persons.

                                      SECTION 5

                                STOCK SUBJECT TO PLAN

     5.1   Number.  Subject to the provisions of Section 5.3, the number of
shares of Stock subject to Awards (including Director Awards) under the Plan may
not exceed 1,700,000 shares of Stock. The shares to be delivered under the Plan
may consist, in whole or in part, of treasury Stock or authorized but unissued
Stock, not reserved for any other purpose. The maximum number of shares of Stock
with respect to which Awards may be granted to any one Employee under the Plan
is 40% of the aggregate number of shares of Stock available for Awards under
Section 5.1.

     5.2   Cancelled, Terminated or Forfeited Awards.  Any shares of Stock
subject to an Award which for any reason are cancelled, terminated or otherwise
settled without the issuance of any Stock shall again be available for Awards
under the Plan.  In the event 

                                     -4-



a Participant pays the exercise price of an Option pursuant to Section 6.4 by 
transferring or having withheld shares of stock, only the net number of 
Shares shall be considered utilized under the Plan and the balance shall 
again be available for Award under the Plan.

     5.3   Adjustment in Capitalization. In the event of any Stock dividend or
Stock split, recapitalization (including, without limitation, the payment of an
extraordinary dividend), merger, consolidation, combination, spin-off,
distribution of assets to stockholders, exchange of shares, or other similar
corporate change, (i) the aggregate number of shares of Stock available for
Awards under Section 5.1 and (ii) the number of shares and exercise price with
respect to Options and the number, prices and dollar value of other Awards, may
be appropriately adjusted by the Committee, whose determination shall be
conclusive. If, pursuant to the preceding sentence, an adjustment is made to the
number of shares of Stock authorized for issuance under the Plan, a
corresponding adjustment shall be made with respect to Director Awards granted
pursuant to Section 7.1.

                                      SECTION 6

                                    STOCK OPTIONS

     6.1   Grant of Options.  Options may be granted to Participants at such
time or times as shall be determined by the Committee.  Options granted under
the Plan may be of two types: (i) Incentive Stock Options and (ii) Nonstatutory
Stock Options. The Committee shall have complete discretion in determining the
number of Options, if any, to be granted to a Participant. Each Option shall be
evidenced by an Option agreement that shall specify the type of Option granted,
the exercise price, the duration of the Option, the number of shares of Stock to
which the Option pertains, the exercisability (if any) of the Option in the
event of death, retirement, disability or termination of employment, and such
other terms and conditions not inconsistent with the Plan as the Committee shall
determine.  Options may also be granted in replacement of or upon assumption of
options previously issued by companies acquired by the Company by merger or
stock purchase, and any options so replaced or assumed may have 

                                     -5-



the same terms including exercise price as the options so replaced or assumed.

     6.2   Option Price.  Nonstatutory Stock Options and Incentive Stock
Options granted pursuant to the Plan shall have an exercise price which is not
less than the Fair Market Value on the date the Option is granted.

     6.3   Exercise of Options.  Options awarded to a Participant under the
Plan shall be exercisable at such times and shall be subject to such
restrictions and conditions as the Committee may impose, subject to the
Committee's right to accelerate the exercisability of such Option in its
discretion. Notwithstanding the foregoing, no Option shall be exercisable for
more than ten years after the date on which it is granted.

     6.4   Payment.  The Committee shall establish procedures governing the
exercise of Options, which shall require that written notice of exercise be
given and that the Option price be paid in full in cash or cash equivalents,
including by personal check, at the time of exercise or pursuant to any
arrangement that the Committee shall approve. The Committee may, in its
discretion, permit a Participant to make payment (i) in Stock already owned by
the Participant valued at its Fair Market Value on the date of exercise (if such
Stock has been owned by the Participant for at least six months) or (ii) by
electing to have the Company retain Stock which would otherwise be issued on
exercise of the Option, valued at its Fair Market Value on the date of exercise.
As soon as practicable after receipt of a written exercise notice and full
payment  of the exercise price, the Company shall deliver to the Participant a
certificate or certificates representing the acquired shares of Stock.  The
Committee may permit a Participant to elect to pay the exercise price upon the
exercise of an Option by authorizing a third party to sell shares of Stock (or a
sufficient portion of the shares) acquired upon exercise of the Option and remit
to the Company a sufficient portion of the sale proceeds to pay the entire
exercise price and any required tax withholding resulting from such exercise.

     6.5   Incentive Stock Options.  Notwithstanding anything in the Plan to
the contrary, no term of this Plan relating to Incentive Stock Options shall be
interpreted, amended or altered,

                                     -6-



nor shall any discretion or authority granted under the Plan be so exercised, 
so as to disqualify the Plan under Section 422 of the Code, or, without the 
consent of any Participant affected thereby, to cause any Incentive Stock 
Option previously granted to fail to qualify for the Federal income tax 
treatment afforded under Section 421 of the Code. 

     6.6   Replacement Options.  The Committee may grant a replacement option
(a "Replacement Option") to any Employee who exercises all or part of an option
granted under this Plan using Qualifying Stock (as herein defined) as payment
for the purchase price.  A Replacement Option shall grant to the Employee the
right to purchase, at the Fair Market Value as of the date of said exercise and
grant, the number of shares of stock equal to the sum of the number of whole
shares (i) used by the Employee in payment of the purchase price for the option
which was exercised and (ii) used by the Employee in connection with applicable
withholding taxes on such transaction.  A Replacement Option may not be
exercised for six months following the date of grant, and shall expire on the
same date as the option which it replaces.  Qualifying Stock is stock which has
been owned by the Employee for at least six months prior to the date of exercise
and has not been used in a stock-for-stock swap transaction within the preceding
six months.

                                      SECTION 7

                                   DIRECTOR AWARDS

     7.1   Amount of Award.  Each Eligible Director shall receive a 
non-discretionary Award of 2,000 shares of stock each year; such Award shall 
be made annually on the date of and following completion of the Company's 
annual stockholders' meeting (commencing with the 1999 annual stockholders' 
meeting). Each Eligible Director shall be issued a common stock certificate 
for such number of shares. Termination of the director's services for any 
reason other than (i) death, (ii) retirement from the Board at mandatory 
retirement age, or (iii) resignation or failure to stand for re-election, in 
any such case with the prior approval of the Board, will result in forfeiture 
of the Stock. If the Stock is forfeited, the director shall return the number 
of 

                                     -7-



forfeited shares of Stock, or equivalent value, to the Company. The number of 
shares of Stock awarded to an Eligible Director annually shall be 
appropriately adjusted in the event of any stock changes as described in 
Section 5.3. In addition, each Eligible Director shall receive a 
non-discretionary Award of a Nonqualified Stock Option for 4,000 shares of 
Stock exercisable at the Fair Market Value of the Company's common stock on 
the date of grant; such Award shall be made annually on the date of and 
following completion of the Company's annual stockholders' meeting 
(commencing with the 1999 annual stockholders' meeting). The number of 
nonqualified options awarded to a director shall be appropriately adjusted in 
the event of any stock changes as described in Section 5.3.

     7.2   No Other Awards.  An Eligible Director shall not receive any other
Award under the Plan.


                                      SECTION 8

                              STOCK APPRECIATION RIGHTS

     8.1   SAR's in Tandem with Options.  Stock Appreciation Rights may be
granted to Participants in tandem with any Option granted under the Plan, either
at or after the time of the grant of such Option, subject to such terms and
conditions, not inconsistent with the provisions of the Plan, as the Committee
shall determine. Each Stock Appreciation Right shall only be exercisable to the
extent that the corresponding Option is exercisable, and shall terminate upon
termination or exercise of the corresponding Option.  Upon the exercise of any
Stock Appreciation Right, the corresponding Option shall terminate.

     8.2   Other Stock Appreciation Rights.  Stock Appreciation Rights may also
be granted to Participants separately from any Option, subject to such terms and
conditions, not inconsistent with the provisions of the Plan, as the Committee
shall determine.


                                      SECTION 9


                                     -8-



                                   RESTRICTED STOCK

     9.1   Grant of Restricted Stock.  The Committee may grant Restricted 
Stock to Participants at such times and in such amounts, and subject to such 
other terms and conditions not inconsistent with the Plan as it shall 
determine.  Each grant of Restricted Stock shall be subject to such 
restrictions, which may relate to continued employment with the Company, 
performance of the Company, or other restrictions, as the Committee may 
determine. Each grant of Restricted Stock shall be evidenced by a written 
agreement setting forth the terms of such Award.  A maximum of 20% of the 
shares of Stock available for issuance under the Plan may be issued as 
Restricted Stock.

     9.2   Removal of Restrictions.  The Committee may accelerate or waive such
restrictions in whole or in part at any time in its discretion.


                                      SECTION 10

                   AMENDMENT, MODIFICATION, AND TERMINATION OF PLAN

     11.1  General.  The Board may from time to time amend, modify or 
terminate any or all of the provisions of the Plan, subject to the provisions 
of this Section 11.1.  The Board may not change the Plan in a manner which 
would prevent outstanding Incentive Stock Options granted under the Plan from 
being Incentive Stock Options without the consent of the optionees concerned. 
Furthermore, the Board may not make any amendment which would (i) 

                                     -9-



materially modify the requirements for participation in the Plan or (ii) 
increase the number of shares of Stock subject to Awards under the Plan 
pursuant to Section 5.1, in each case without the approval of a majority of 
the outstanding shares of Stock entitled to vote thereon.  No amendment or 
modification shall affect the rights of any Employee with respect to a 
previously granted Award, nor shall any amendment or modification affect the 
rights of any Eligible Director pursuant to a previously granted Director 
Award.

     11.2  Termination of Plan.  No further Options shall be granted under the
Plan subsequent to December 31, 2009, or such earlier date as may be determined
by the Board.

     12.1  Nontransferability of Awards.  Except as otherwise provided by the

assigned, or otherwise alienated or hypothecated, other than by will or by the
laws of descent and distribution. 

     12.2  Beneficiary Designation.  Each Participant under the Plan may from
time to time name any beneficiary or beneficiaries (who may be named contingent
or successively) to whom any benefit under the Plan is to be paid or by whom any
right under the Plan is to be exercised in case of his death. Each designation
will revoke all prior designations by the same Participant shall be in a form
prescribed by the Committee, and will be effective only when filed in writing
with the Company.  In the absence of any such designation, Awards outstanding at
death may be exercised by the Participant's surviving spouse, if any, or
otherwise by his estate.

     12.3  No  Guarantee of Employment or Participation.  Nothing in the Plan
shall interfere with or limit in any way the right of 

                                     -10-



the Company or any Subsidiary to terminate any Participant's employment at 
any time, nor confer upon any Participant any right to continue in the employ 
of the Company or any Subsidiary. No Employee shall have a right to be 
selected as a Participant, or, having been so selected, to receive any future 
Awards.

     12.4  Tax Withholding.  The Company shall have the power to withhold, or
require a Participant or Eligible Director to remit to the Company, an amount
sufficient to satisfy federal, state, and local withholding tax requirements on

requirements are satisfied. The Committee may, in its discretion, permit a
Participant to elect, subject to such conditions as the Committee shall impose,
(i) to have shares of Stock otherwise issuable under the Plan withheld by the
Company or (ii) to deliver to the Company previously acquired shares of Stock,
in each case having a Fair Market Value sufficient to satisfy all or part of the
Participant's estimated total federal, state and local tax obligation associated
with the transaction.

           generally in the election of directors; or

                                     -11-


     (ii)  Individuals who, as of the date hereof, constitute the Board (as of
           the date hereof the "Incumbent Board") cease for any reason to
           constitute at least a majority of the Board, provided that any
           person becoming a director subsequent to the date hereof whose
           election, or nomination for the election by the Company's
           stockholders, was approved by a vote of at least a majority of the
           directors then comprising the Incumbent Board shall be, for purposes
           of this Plan, considered as though such person were a member of the
           Incumbent Board; or

           merger or consolidation, in each case, with respect to which persons
           who were the stockholders of the Company immediately prior to such
           reorganization, merger or consolidation do not, immediately
           thereafter, own more than 50% of the combined voting power entitled
           to vote generally in the election of directors of the reorganized,
           merged or consolidated company's then outstanding voting securities,
           or a liquidation or dissolution of the Company or of the sale of all
           or substantially all of the assets of the Company.

     12.6  Company Intent.  The Company intends that the Plan comply in all
respects with Rule 16b-3 under the Act, and any ambiguities or inconsistencies
