     The Plan shall be administered by a Committee of Directors who are both

or final rules issued thereunder).  The Committee shall be appointed by the
Board and shall serve at the pleasure of the Board.

     The Committee shall have the power and authority to grant Awards
consistent with the terms of the Plan, including the power and authority:

          i.    to select from among the eligible persons and entities
               described in Section 4 those to whom Awards may from time to
               time be granted;

          ii.  to determine the time or times of grant, and the extent, if any,
               of Incentive Stock Options, Non-Qualified Stock Options, Stock
               Appreciation Rights, Restricted Stock, Unrestricted Stock,
               Deferred Stock, Performance Units, and any Other Stock-based
               Awards, or any combination of the foregoing, granted to any one
               or more participants;

          iii. to determine the number of shares to be covered by any Award;

          iv.  to determine the terms and conditions, including restrictions,
               not inconsistent with the terms of the Plan, of any Award, which
               terms and conditions may differ among individual Awards and
               participants;

          v.   to determine whether, to what extent, and under what
               circumstances Stock and other amounts payable with respect to an
               Award shall be deferred either automatically or at the election
               of the participant and whether and to what extent the Company
               shall pay or credit amounts equal to interest (at rates
               determined by the Committee) or dividends or deemed dividends on
               such deferrals; and

          vi.  to adopt, alter, and repeal such rules, guidelines and practices
               for administration of the Plan and for its own acts and
               proceedings as it shall deem advisable; to interpret the terms
               and provisions of the Plan and any Award (including related
               Award Agreements); to make all determinations it deems advisable
               for the administration of the Plan; to decide all disputes
               arising in connection with the Plan; and to otherwise supervise

persons, including the Company and Plan participants.

                                   Page 3

SECTION 3.  Shares Issuable Under the Plan; Mergers; Substitution

     a.        Shares Issuable.  The maximum number of shares of Stock reserved
          and available for issuance under the Plan shall be 3,000,000,
          including shares issued in lieu of or upon reinvestment of dividends
          arising from Awards.  Of this number, 150,000 are reserved and
          available for issuance under stock options granted to Non-employee
          Directors under Section 6(m).  For purposes of the foregoing
          limitations and to the maximum extent consistent with continued
          qualification of the Plan under Section 422 of the Code and Rule
          16b-3 promulgated under the Act, Awards and Stock which are
          forfeited, reacquired by the Company, or satisfied without the
          issuance of Stock shall not be counted.  Subject to such overall
          limitation, shares may be issued up to such maximum pursuant to any
          type or types of Award, including Incentive Stock Options.  Shares
          issued under the Plan may be authorized but unissued shares or shares
          reacquired by the Company.

          The maximum number of shares of Stock for which any individual (other
          than a Non-employee Director) may be issued Stock Options under the
          Plan during the limitation period shall be 750,000 shares.  The
          maximum number of shares of Stock as to which any individual may be
          issued Stock Appreciation Rights under the Plan during the limitation
          period shall likewise be 750,000 shares.  For purposes of the two
          preceding sentences, (i) the limitation period shall be the period
          beginning January 1, 1994 and ending December 1, 1999, and (ii) Stock
          Options granted prior to January 1, 1994 but subject to shareholder
          approval occurring after January 1, 1994 shall be treated as having
          been granted during the limitation period.  The limitations described
          in this paragraph shall be construed and applied in accordance with
          Section 162(m) of the Code and the regulations thereunder.  Subject
          to the foregoing, a Stock Option or Stock Appreciation Right that is
          canceled and reissued, or repriced, shall be treated as a new Award,
          and both the old Award and the new Award shall count against the
          applicable limit described in this paragraph.

     b.        Stock Dividends, Mergers, etc.  In the event of a stock
          dividend, stock split, or similar change in capitalization affecting
          the Stock, the Committee shall make appropriate adjustments in (i)
          the number and kind of shares of stock or securities on which Awards
          may thereafter be granted, (ii) the number and kind of shares
          remaining subject to outstanding Awards, and (iii) the option or
          purchase price in respect of such shares.  In the event of any
          merger, consolidation, dissolution, or liquidation of the Company,
          the Committee in its sole discretion may, as to any outstanding
          Awards, make such substitution or adjustment in the aggregate number
          of shares reserved for issuance under the Plan and in the number and
          purchase price (if any) of shares subject to such Awards as it may
          determine, or accelerate, amend, or terminate such Awards upon such

                                      Page 4

          terms and conditions as it shall provide (which, in the case of the
          termination of the vested portion of any Award, shall require payment
          or other consideration which the Committee deems equitable in the
          circumstances); provided, however, that no adjustment pursuant to
          this sentence shall affect options granted under subsection (m) of
          Section 6 of the Plan if the effect of such adjustment shall cause
          the members of the Committee to fail to be disinterested persons
          under Section 16(b) of the Act.

     c.        Substitute Awards.  The Company may grant Awards under the Plan
          in substitution for stock and stock based awards held by employees of
          or other persons providing services to another corporation who
          concurrently become employees of or providers of service to the
          Company or a Subsidiary as the result of a merger or consolidation of
          the employing corporation with the Company or a Subsidiary or the
          acquisition by the Company or a Subsidiary of property or stock of
          the employing corporation.  The Committee may direct that the
          substitute awards be granted on such terms and conditions as the
          Committee considers appropriate in the circumstances.  The shares
          which may be delivered under such substitute Awards shall be in
          addition to the maximum number of shares provided for in the first
          paragraph of Section 3(a) only to the extent that the substitute
          Awards are both granted to persons whose relationship to the Company
          does not make (and is not expected to make) them subject to
          Section 16(b) of the Act and are granted in substitution for awards
          issued under a plan approved, to the extent then required under
          Rule 16b-3 (or any successor rule under the Act) by the stockholders
          of the entity which issued such predecessor awards.

SECTION 4.  Eligibility.

     Participants in the Plan will be such full or part time officers and other
key employees of the Company and its Subsidiaries ("Employees") and other
persons or entities who are responsible for or contribute to the management,
growth, or profitability of the Company and its Subsidiaries and who are
selected from time to time by the Committee.  Notwithstanding the foregoing,
persons who are directors of the Company, other than any such person who is a
full time employee, shall not be eligible for awards under the Plan except as
provided in Section 6(m).

SECTION 5.  Limitations on Term and Dates of Awards.

     a.        Duration of Awards.  Subject to Sections 15(a), 15(c), and 15(d)
          below, no restrictions or limitations on Awards shall extend beyond
          10 years (or 10 years and one day in the case of Non-Qualified Stock
          Options) from the grant date, except that deferrals, elected by
          participants, of the receipt of Stock or other benefits under the
          Plan may extend beyond such date.

                                      Page 5


     b.        Latest Grant Date.  No Award shall be granted after December 1,
          1999, but then-outstanding Awards may extend beyond such date.

SECTION 6.  Stock Options.

     Any stock option granted under the Plan shall be in such form as the
Committee may from time to time approve.

     Stock Options granted under the Plan may be either Incentive Stock Options
or Non-Qualified Stock Options.  To the extent that any option does not qualify
as an Incentive Stock Option, it shall constitute a Non-Qualified Stock Option. 
Incentive Stock Options may be granted only to Employees.

     Anything in the Plan to the contrary notwithstanding, no term of this Plan
relating to Incentive Stock Options shall be interpreted, amended, or altered,
nor shall any discretion or authority granted to the Committee under the Plan
be so exercised, so as to disqualify the Plan or, without the consent of the
optionee, any Incentive Stock Option under Section 422 of the Code.

     Stock Options granted under the Plan shall be subject to the following
terms and conditions and shall contain such additional terms and conditions,
not inconsistent with the terms of the Plan, as the Committee shall deem
desirable.

     a.        Option Price.  The option price per share of Stock purchasable
          under a Stock Option shall be determined by the Committee at the time
          of grant but shall be, in the case of Incentive Stock Options, not
          less than 100% of Fair Market Value on the date of grant and, in the
          case of Non-Qualified Stock Options, not less than 50% of Fair Market
          Value on the date of grant.  If an employee owns or is deemed to own
          (by reason of the attribution rules applicable under Section 424(d)
          of the Code) more than 10% of the combined voting power of all
          classes of stock of the Company or any Subsidiary or parent
          corporation and an Incentive Stock Option is granted to such
          employee, the option price shall be no less than 110% of Fair Market
          Value on the date of grant.

     b.        Option Term.  The term of each Stock Option shall be fixed by
          the Committee, but no Incentive Stock Option shall be exercisable
          more than 10 years after the date the option is granted and no Non-
          Qualified Stock Option shall be exercisable more than 10 years and
          one day after the date the option is granted.  If an employee owns or
          is deemed to own (by reason of the attribution rules of Section
          424(d) of the Code) more than 10% of the combined voting power of all
          classes of stock of the Company or any Subsidiary or parent

                                       Page 6

          corporation and an Incentive Stock Option is granted to such
          employee, the term of such option shall be no more than five years
          from the date of grant.

     c.        Exercisability.  Stock Options shall be exercisable at such
          future time or times, whether or not in installments, as shall be
          determined by the Committee at or after the date of grant.  The
          Committee may at any time accelerate the exercisability of all or any
          portion of any Stock Option.

     d.        [Intentionally left blank.]

     e.        Method of Exercise.  Stock Options may be exercised in whole or
          in part, by giving written notice of exercise to the Company
          specifying the number of shares to be purchased.  Such notice shall
          be accompanied by payment in full of the purchase price, either by
          certified or bank check or other instrument acceptable to the
          Committee.  As determined by the Committee, in its discretion, at
          (or, in the case of Non-Qualified Stock Options, at or after) the
          time of grant, payment in full or in part may also be made in the
          form of shares of Stock not then subject to restrictions under any
          Company plan (but which may include shares the disposition of which
          constitutes a disqualifying disposition for purposes of obtaining
          incentive stock option treatment for federal tax purposes), unless
          the Board should in any case determine otherwise.  Such surrendered
          shares shall be valued at Fair Market Value on the exercise date.  An
          optionee shall have the rights of a shareholder only as to shares
          acquired upon the exercise of a Stock Option and not as to
          unexercised Stock Options.

     f.        Non-transferability of Options.  No Stock Option shall be
          transferable by the optionee otherwise than by will or by the laws of
          descent and distribution, and all Stock Options shall be exercisable,
          during the optionee's lifetime, only by the optionee. 

     g.        Termination by Death.  If an optionee's employment by or other
          service relationship with the Company and its Subsidiaries terminates
          by reason of death, the Stock Option may thereafter be exercised,
          both as to that portion which was exercisable by the optionee
          immediately prior to death and, except as otherwise determined by the
          Committee, as to any remaining portion, by the legal representative
          or legatee of the optionee, for a period of three years (or such
          other period, not to exceed three years, as the Committee shall
          specify at or after the time of grant) from the date of death or
          until the expiration of the stated term of the option, if earlier. 
 
     h.        Termination by Reason of Disability.  Any Stock Option held by
          an optionee whose employment by or whose service relationship with

                                     Page 7

          the Company and its Subsidiaries has terminated, or who has been
          designated an inactive employee, by reason of Disability may
          thereafter be exercised to the extent it was exercisable at the time
          of the earlier of such termination or such designation (or on such
          accelerated basis as the Committee shall at any time determine prior
          to such termination or designation) for a period of three years (or
          such other period, not to exceed three years, as the Committee shall
          specify at or after the time of grant) from the date of such
          termination of employment or other service relationship or
          designation or until the expiration of the stated term of the option,
          if earlier.  Except as otherwise provided by the Committee at the
          time of grant, the death of an optionee during the final year of such
          exercise period shall extend such period for one year following
          death, or until the expiration of the stated term of the option, if
          earlier.  The Committee shall have the authority to determine whether
          a participant has been terminated or designated an inactive employee
          by reason of Disability.

     i.        Termination by Reason of Normal Retirement.  If an optionee's
          employment by the Company and its Subsidiaries terminates by reason
          of Normal Retirement, any Stock Option held by such optionee may
          thereafter be exercised to the extent that it was then exercisable
          (or on such accelerated basis as the Committee shall at any time
          determine) for a period of three years (or such other period, not to
          exceed three years, as the Committee shall specify at or after the
          time of grant) from the date of Normal Retirement or until the
          expiration of the stated term of the option, if earlier.  Except as
          otherwise provided by the Committee at the time of grant, the death
          of an optionee during the final year of such exercise period shall
          extend such period for one year following death, or until the
          expiration of the stated term of the option, if earlier.

     j.        Other Termination.  Unless otherwise determined by the
          Committee, if an optionee's employment by or other service
          relationship with the Company or its Subsidiaries terminates for any
          reason other than death, Disability or Normal Retirement, any Stock
          Option held by such optionee may thereafter be exercised to the
          extent it was exercisable on the date of termination of employment or
          other termination of the service relationship (or on such accelerated
          basis as the Committee shall determine at or after the time of grant)
          for a period of sixty (60) days (or such longer period up to three
          years as the Committee shall specify at or after the time of grant)
          from the date of termination of employment or other termination of
          the service relationship or until the expiration of the stated term
          of the option, if earlier, provided, that if the optionee's
          employment or other service relationship is terminated for "cause" as
          a result of the optionee's misconduct which, in the judgment of the
          Committee, casts discredit on him or her, or is otherwise harmful to
          the business, interests or reputation of the Company, its parent, or
          a Subsidiary, all Stock Options shall terminate immediately.

                                       Page 8


          For purposes of the preceding paragraph, if an optionee's employment
          by the Company or its Subsidiaries is terminated under circumstances
          entitling the optionee to cash severance pay under any written
          severance plan, program, policy, or agreement of the Company or its
          Subsidiaries in force at the time of such termination of employment
          (a "Severance Program"), then except as otherwise determined by the
          Committee any Stock Option held by the optionee at termination of
          employment shall be treated as "exercisable on the date of
          termination of employment" as to those shares for which it was in
          fact exercisable immediately prior to termination of employment plus
          any additional shares for which it would have become exercisable
          during the severance period (as hereinafter defined) had the optionee
          remained employed by the Company or its Subsidiaries.  For purposes
          of the preceding sentence, the severance period in the case of any
          terminated employee entitled to severance under a Severance Program
          shall be the period of weeks over which his or her cash severance, if
          paid as salary continuation, would have been paid (whether or not
          such severance is in fact so paid in such form).

     k.        Incentive Stock Options.  Notwithstanding any designation of a
          Stock Option as an Incentive Stock Option, such Stock Option shall be
          treated for tax purposes as a Non-Qualified Stock Option to the
          extent prescribed under Section 422(d) of the Code.

     l.        Form of Settlement.  Subject to Sections 15(a), 15(c), and 15(d)
          below, shares of Stock issued upon exercise of a Stock Option shall
          be free of all restrictions under the Plan, except as provided in the
          following sentence.  The Committee may provide at time of grant that
          the shares to be issued upon the exercise of a Stock Option shall be
          in the form of Restricted Stock or Deferred Stock, or may reserve the
          right to so provide after time of grant.

     m.        Options Granted to Non-employee Directors.  Subject to the
          limits and adjustment provisions set forth in Section 3, each Non-
          employee Director serving in such position on the third business day
          following the date of each annual meeting of the stockholders of the
          Company (such third day being hereinafter referred to as the
          "determination date") shall be granted effective as of the
          determination date a Non-Qualified Stock Option covering 3,000 shares
          of Stock.  The option price under such Stock Option shall be the fair
          market value of the Stock on the determination date.  If, on account
          of the limit set forth in the second sentence of Section 3(a), there
          are insufficient shares as of any determination date to permit the
          grant of a Stock Option covering 3,000 shares (as adjusted) to each
          Non-employee Director then eligible for a grant, the number of shares
          available for grant shall be allocated evenly (disregarding any
          fractional shares) among the Non-employee Directors then eligible for
          a grant (an "incomplete grant"), and if additional shares later
          become available under said limit while any such Non-employee

                                      Page 9

          Director who received an incomplete grant remains a Non-employee
          Director and during the terms of the Plan, such Non-employee Director
          shall be granted automatically upon such availability a supplemental
          Non-Qualified Stock Option covering a number of shares equal to the
          lesser of (a) 3,000 shares (appropriately adjusted pursuant to
          Section 3) less the number of shares (as so adjusted) covered by the
          incomplete grant, or (b) the number of shares then available under
          Section 3, subject to allocation among Non-employee Directors in
          accordance with the preceding provisions of this paragraph.  The
          option price of any supplemental Stock Option shall be the fair
          market value of the Stock on the date of grant (i.e., the date of the
          availability of additional shares).

          Each Stock Option granted under this subsection (m) may be exercised
          as follows:

          (1)  (A) 25% of the shares subject to such Stock Option may be
          purchased commencing one year after the date of grant, and 

               (B) an additional 25% of such shares may be purchased commencing
          on the second, third, and fourth anniversaries of the date of grant;
          and

          (2)  subject to (1) above, such Stock Option may only be exercised
          during the five-year period beginning on the date the Stock Option is
          granted.

          To the extent that a Stock Option granted hereunder to a Non-employee
          Director is not exercised when it initially becomes exercisable, it
          shall be carried forward and be exercisable until the expiration of
          the term of such Stock Option as described in (2) above; provided,
          that if the Non-employee Director ceases to be a Director for any
          reason other than death, any Stock Option held by such Non-employee
          Director may thereafter be exercised, as to that portion of the Stock
          Option which was exercisable immediately prior to the date the
          optionee ceased to be a Director, only within the three-month period
          beginning from such date (but in no event beyond the five-year term
          described in (2) above); and further provided, that if a Non-
          employee Director ceases to be a Director by reason of death, any
          Stock Option held by such Non-employee Director immediately prior to
          death, whether or not then exercisable, shall be exercisable in whole
          or in part at any time within the three-month period beginning from
          the date of death (but in no event beyond the five-year term
          described in (2) above) and then shall terminate.

          All options granted under this subsection (m) may be exercised by
          delivery of cash and/or Stock.

                                        Page 10


          Non-employee Directors shall not be granted any Award or Grant under
          this Plan (including any Stock Appreciation Right or Supplemental
          Grant) other than Stock Options as specifically provided hereunder.

SECTION 7.  Stock Appreciation Rights; Discretionary Payments.

     a.        Nature of Stock Appreciation Right.  A Stock Appreciation Right
          is an Award entitling the recipient to receive an amount in cash or
          shares of Stock (or forms of payment permitted under paragraph (e)
          below) or a combination thereof having a value equal to (or if the
          Committee shall so determine at time of grant, less than) the excess
          of the Fair Market Value of a share of Stock on the date of exercise
          over the Fair Market Value of a share of Stock on the date of grant
          (or over the option exercise price, if the Stock Appreciation Right
          was granted in tandem with a Stock Option) multiplied by the number
          of shares with respect to which the Stock Appreciation Right shall
          have been exercised, with the Committee having the right to determine
          the form of payment.

     b.        Grant and Exercise of Stock Appreciation Rights.  Stock
          Appreciation Rights may be granted in tandem with, or independently
          of, any Stock Option granted under the Plan.  In the case of a Stock
          Appreciation Right granted in tandem with a Non-Qualified Stock
          Option, such Right may be granted either at or after the time of the
          grant of such option.  In the case of a Stock Appreciation Right
          granted in tandem with an Incentive Stock Option, such Right may be
          granted only at the time of the grant of the option.

          A Stock Appreciation Right or applicable portion thereof granted in
          tandem with a given Stock Option shall terminate and no longer be
          exercisable upon the termination or exercise of the related Stock
          Option, except that a Stock Appreciation Right granted with respect
          to less than the full number of shares covered by a related Stock
          Option shall not be reduced until the exercise or termination of the
          related Stock Option exceeds the number of shares not covered by the
          Stock Appreciation Right.

     c.        Terms and Conditions of Stock Appreciation Rights.  Stock
          Appreciation Rights shall be subject to such terms and conditions as
          shall be determined from time to time by the Committee, subject to
          the following:

          i.   Stock Appreciation Rights granted in tandem with Stock Options
               shall be exercisable only at such time or times and to the
               extent that the related Stock Options shall be exercisable.

                                      Page 11


          ii.  Upon the exercise of a Stock Appreciation Right, the applicable
               portion of any related Stock Option shall be surrendered.

          iii. Stock Appreciation Rights granted in tandem with a Stock Option
               shall be transferable only with such Stock Option.  Stock
               Appreciation Rights shall not be transferable otherwise than by
               will or the laws of descent and distribution.  All Stock
               Appreciation Rights shall be exercisable during the
               participant's lifetime only by the participant or the
               participant's legal representative.

          iv.  A Stock Appreciation Right granted in tandem with an Incentive
               Stock Option may be exercised only when the market price of the
               Stock subject to the Incentive Stock Option exceeds the exercise
               price of such option.

     d.        Discretionary Payments.  Notwithstanding that a Stock Option at
          the time of exercise shall not be accompanied by a related Stock
          Appreciation Right, if the market price of the shares subject to such
          Stock Option exceeds the exercise price of such Stock Option at the
          time of its exercise, the Committee may, in its discretion, cancel
          such Stock Option, in which event the Company shall pay to the person
          exercising such Stock Option an amount equal to the difference
          between the Fair Market Value of the Stock to have been purchased
          pursuant to such exercise of such Stock Option (determined on the
          date the Stock Option is canceled) and the aggregate consideration to
          have been paid by such person upon such exercise.  Such payment shall
          be by check or in Stock (or in a form of payment permitted under
          paragraph (e) below) having a Fair Market Value (determined on the
          date the payment is to be made) equal to the amount of such payments
          or any combination thereof, as determined by the Committee.  The
          Committee may exercise its discretion under the first sentence of
          this paragraph (d) only in the event of a written request of the
          person exercising the option, which request shall not be binding on
          the Committee.

     e.        Settlement in the Form of Restricted Shares or Rights to Receive
          Deferred Stock.  Subject to Sections 15(a), 15(c), and 15(d) below,
          shares of Stock issued upon exercise of a Stock Appreciation Right or
          as a Discretionary Payment shall be free of all restrictions under
          the Plan, except as provided in the following sentence.  The
          Committee may provide at time of grant in the case of a Stock
          Appreciation Right (and at the time of payment in the case of a
          Discretionary Payment) that such shares shall be in the form of
          shares of Restricted Stock or rights to acquire Deferred Stock, or in
          the case of a Stock Appreciation Right may reserve the right to so
          provide at any time after the time of grant.  Any such shares and any
          shares subject to rights to acquire Deferred Stock shall be valued at

                                        Page 12

          Fair Market Value on the date of exercise of the Stock Appreciation
          Right or the date the Stock Option is cancelled in the case of
          Discretionary Payments.

     f.        Rules Relating to Exercise.  In the case of a participant
          subject to the restrictions of Section 16(b) of the Act, no stock
          appreciation right (as referred to in Rule 16b-3(e) or any successor
          Rule under the Act) shall be exercised (and no request or payment
          under paragraph (d) above shall be honored or made) except in
          compliance with any applicable requirements of Rule 16b-3(e) or any
          successor rule.  Notwithstanding paragraph (a) above, in the event of
          such exercise (or request and payment) during an exercise period
          currently prescribed by such rule, the Committee may prescribe, by
          rule of general application, such other measure of value as it may
          determine but not in excess of the highest per share closing sale
          price of the Common Stock reported on the New York Stock Exchange
          Composite Transactions Index during such period and, where a Stock
          Appreciation Right relates to an Incentive Stock Option, not in
          excess of an amount consistent with the qualification of such Stock
          Option as an "incentive stock option" under Section 422 of the Code. 

SECTION 8.  Restricted Stock; Unrestricted Stock.

     a.        Nature of Restricted Stock Award.  A Restricted Stock Award is
          an Award entitling the recipient to acquire shares of Stock for a
          purchase price (which may be zero), subject to such conditions,
          including a Company right during a specified period or periods to
          repurchase such shares at their original purchase price (or to
          require forfeiture of such shares, if the purchase price was zero)
          upon the participant's termination of employment or other service
          relationship, as the Committee may determine at the time of grant. 
          The original purchase price, if any, shall be determined by the
          Committee, but if any purchase price is payable in an amount which
          exceeds the lesser of the par value of the shares or 10% of the fair
          market value of the Common Stock on the award date, it shall be equal
          to at least 50% of the fair market value of the Common Stock on the
          award date.

     b.        Award Agreement.  A participant who is granted a Restricted
          Stock Award shall have no rights with respect to such Award unless
          the participant shall have accepted the Award within 60 days (or such
          shorter date as the Committee may specify) following the award date
          by making payment to the Company by certified or bank check or other
          instrument acceptable to the Committee in an amount equal to the
          specified purchase price, if any, of the shares covered by the Award
          and by executing and delivering to the Company a Restricted Stock
          Award Agreement in such form as the Committee shall determine. 

                                      Page 13


     c.        Rights as a Shareholder.  Upon complying with paragraph (b)
          above, a participant shall have all the rights of a shareholder with
          respect to the Restricted Stock including voting and dividend rights,
          subject to nontransferability restrictions and Company repurchase or
          forfeiture rights described in this Section and subject to any other
          conditions contained in the Award Agreement.  Unless the Committee
          shall otherwise determine, certificates evidencing shares of
          Restricted Stock shall remain in the possession of the Company until
          such shares are free of any restrictions under the Plan. 

     d.        Restrictions.  Shares of Restricted Stock may not be sold,
          assigned, transferred, pledged, or otherwise encumbered or disposed
          of except as specifically provided herein.  In the event of
          termination of employment or other service relationship of the
          participant with the Company and its Subsidiaries for any reason,
          such shares shall be resold to the Company at their purchase price,
          or forfeited to the Company if the purchase price was zero, except as
          set forth below.

          i.   The Committee at the time of grant shall specify the date or
               dates (which may depend upon or be related to the attainment of
               performance goals and other conditions) on which the
               nontransferability of the Restricted Stock and the obligation to
               resell such shares to the Company shall lapse.  The Committee at
               any time may accelerate such date or dates and otherwise waive
               or, subject to Section 13, amend any conditions of the Award. 

          ii.  Except as may otherwise be provided in the Award Agreement, in
               the event of termination of employment or other service
               relationship of a participant with the Company and its
               Subsidiaries for any reason (including death), the participant
               or the participant's legal representative shall offer to resell
               to the Company, at the price paid therefor, all Restricted
               Stock, and the Company  shall have the right to purchase the
               same at such price, or if the price was zero to require
               forfeiture of the same, provided that except as provided in the
               Award Agreement, the Company must exercise such right of
               repurchase or forfeiture not later than the 60th day following
               such termination of employment or other service relationship.

     e.        Waiver, Deferral, and Investment of Dividends.  The Restricted
          Stock Award Agreement may require or permit the immediate payment,
          waiver, deferral, or investment of dividends paid on the Restricted
          Stock.

     f.        Unrestricted Stock.  The Committee may, in its sole discretion,
          grant (or sell at a purchase price not to exceed the lesser of the
          par value of the shares or 10% of the fair market value of the Common
          Stock at the time of sale) to any participant shares of Stock free of
          restrictions under the Plan ("Unrestricted Stock").  Shares of

                                       Page 14

          Unrestricted Stock may be granted or sold as described in the
          preceding sentence in respect of past services or other valid
          consideration.  Any sale of Unrestricted Stock must take place within
          60 days after the time of grant of the right to purchase such shares.

SECTION 9.  Deferred Stock Awards.

     a.        Nature of Deferred Stock Award.  A Deferred Stock Award is an
          award entitling the recipient to acquire shares of Stock without
          payment in one or more installments at a future date or dates, all as
          determined by the Committee.  The Committee may also condition such
          acquisition on the attainment of specified performance goals.

     b.        Award Agreement.  A participant who is granted a Deferred Stock
          Award shall have no rights with respect to a such Award unless within
          60 days of the grant of such Award or such shorter period as the
          Committee may specify, the participant shall have accepted the Award
          by executing and delivering to the Company a Deferred Stock Award
          Agreement.

     c.        Restrictions on Transfer.  Deferred Stock Awards and all rights
          with respect to such Awards may not be sold, assigned, transferred,
          pledged, or otherwise encumbered.  Rights with respect to such Awards
          shall be exercisable during the participant's lifetime only by the
          participant or the participant's legal representative.

     d.        Rights as a Shareholder.  A participant receiving a Deferred
          Stock Award will have rights of a shareholder only as to shares
          actually received by the participant under the Plan and not with
          respect to shares subject to the Award but not actually received by
          the participant.  A participant shall be entitled to receive a stock
          certificate for shares of Deferred Stock only upon satisfaction of
          all conditions therefor specified in the Deferred Stock Award
          Agreement.

     e.        Termination.  Except as may otherwise be provided in the Award
          Agreement, a participant's rights in all Deferred Stock Awards shall
          automatically terminate upon the participant's termination of
          employment by or other service relationship with the Company and its
          Subsidiaries for any reason (including death).

     f.        Acceleration, Waiver, etc.  At any time prior to the
          participant's termination of employment or other service relationship
          the Committee may in its discretion accelerate, waive, or, subject to
          Section 13, amend any or all of the restrictions or conditions
          imposed under any Deferred Stock Award.

                                      Page 15


     g.        Payments in Respect of Deferred Stock.  Without limiting the
          right of the Committee to specify different terms, the Deferred Stock
          Award Agreement may either make no provisions for, or may require or
          permit the immediate payment, deferral, or investment of amounts
          equal to, or less than, any cash dividends which would have been
          payable on the Deferred Stock had such stock been outstanding, all as
          determined by the Committee in its sole discretion.

SECTION 10.   Performance Unit Awards.

     a.        Nature of Performance Units.  A Performance Unit Award is an
          award entitling the recipient to acquire cash or shares of Stock, or
          a combination of cash and Stock, upon the attainment of specified
          performance goals.  The Committee in its sole discretion shall
          determine whether and to whom Performance Unit Awards shall be made,
          the performance goals applicable under each such Award, the periods
          during which performance is to be measured, and all other limitations
          and conditions applicable to the awarded Performance Unit. 
          Performance Units may be awarded independent of or in connection with
          the granting of any other Award under the Plan. 

     b.        Award Agreement.  A participant shall have no rights with
          respect to a Performance Unit Award unless within 60 days of the
          grant of such Award or such shorter period as the Committee may
          specify, the participant shall have accepted the Award by executing
          and delivering to the Company a Performance Unit Award Agreement.

     c.        Restrictions on Transfer.  Performance Unit Awards and all
          rights with respect to such Awards may not be sold, assigned,
          transferred, pledged, or otherwise encumbered, and if exercisable
          over a specified period, shall be exercisable during the
          participant's lifetime only by the participant or the participant's
          legal representative. 

     d.        Rights as a Shareholder.  A participant receiving a Performance
          Unit Award will have rights of a shareholder only as to shares
          actually received by the participant under the Plan and not with
          respect to shares subject to the Award but not actually received by
          the participant.  A participant shall be entitled to receive a stock
          certificate evidencing the acquisition of shares of Stock under a
          Performance Unit Award only upon satisfaction of all conditions
          therefor specified in the Performance Unit Award Agreement. 

     e.        Termination.  Except as may otherwise be provided by the
          Committee at any time prior to termination of employment or other
          service relationship, a participant's rights in all Performance Unit

                                      Page 16

          Awards shall automatically terminate upon the participant's
          termination of employment by or other service relationship with the
          Company and its Subsidiaries for any reason (including death). 

     f.        Acceleration, Waiver, etc.  At any time prior to the
          participant's termination of employment by or other service
          relationship with the Company and its Subsidiaries, the Committee may
          in its sole discretion accelerate, waive, or, subject to Section 13,
          amend any or all of the goals, restrictions, or conditions imposed
          under any Performance Unit Award.

     g.        Exercise.  The Committee in its sole discretion shall establish
          procedures to be followed in exercising any Performance Unit, which
          procedures shall be set forth in the Performance Unit Award
          Agreement.  The Committee may at any time provide that payment under
          a Performance Unit shall be made, upon satisfaction of the applicable
          performance goals, without exercise by the participant.  Except as
          otherwise specified by the Committee, (i) a Performance Unit granted
          in tandem with a Stock Option may be exercised only while the Stock
          Option is exercisable, and (ii) the exercise of a Performance Unit
          granted in tandem with any Award shall reduce the number of shares
          subject to the related Award on such basis as is specified in the
          Performance Unit Award Agreement. 

SECTION 11.  Other Stock-Based Awards; Supplemental Grants.

     a.        Nature of Awards.  The Committee may grant other Awards under
          which Stock is or may in the future be acquired ("Other Stock-based
          Awards").  Such awards may include, without limitation, debt
          securities convertible into or exchangeable for shares of Stock upon
          such conditions, including attainment of performance goals, as the
          Committee shall determine.  Subject to the purchase price limitations
          in paragraph (b) below, such convertible or exchangeable securities
          may have such terms and conditions as the Committee may determine at
          the time of grant.  However, no convertible or exchangeable debt
          shall be issued unless the Committee shall have provided (by Company
          right of repurchase, right to require conversion or exchange, or
          other means deemed appropriate by the Committee) a means of avoiding
          any right of the holders of such debt to prevent a Company
          transaction by reason of covenants in such debt.

     b.        Purchase Price; Form of Payment.  The Committee may determine
          the consideration, if any, payable upon the issuance or exercise of
          an Other Stock-based Award.  However, no shares of Stock (whether
          acquired by purchase, conversion, or exchange or otherwise) shall be
          issued unless (i) issued at no cost to the recipient (or for a
          purchase price not in excess of the lesser of the par value of the
          Shares or 10% of the Fair Market Value of the Stock as of the time of
          sale), or (ii) sold, exchanged, or converted by the Company, and the
          Company shall have received payment for such Stock or securities so

                                        Page 17

          sold, exchanged, or converted equal to at least 50% of Fair Market
          Value of the Stock on the grant or effective date, or the exchange or
          conversion date, under the Award, as specified by the Committee.  The
          Committee may permit payment by certified check or bank check or
          other instrument acceptable to the Committee or by surrender of other
          shares of Stock (excluding shares then subject to restrictions under
          the Plan). 

     c.        Forfeiture of Awards; Repurchase of Stock; Acceleration or
          Waiver of Restrictions.  The Committee may determine the conditions

                                    PAGE 16

          under which an Other Stock-based Award shall be forfeited or, in the
          case of an Award involving a payment by the recipient, the conditions
          under which the Company may or must repurchase such Award or related
          Stock.  At any time the Committee may in its sole discretion
          accelerate, waive, or, subject to Section 13, amend any or all of the
          limitations or conditions imposed under any Other Stock-based Award.

     d.        Award Agreements.  A participant shall have no rights with
          respect to any Other Stock-based Award unless within 60 days after
          the grant of such Award (or such shorter period as the Committee may
          specify) the participant shall have accepted the Award by executing
          and delivering to the Company an Other Stock-based Award Agreement.

     e.        Nontransferability.  Other Stock-based Awards may not be sold,
          assigned, transferred, pledged, or encumbered except as may be
          provided in the Other Stock-based Award Agreement.  However, in no
          event shall any Other Stock-based Award be transferred other than by
          will or by the laws of descent and distribution or be exercisable
          during the participant's lifetime by other than the participant or
          the participant's legal representative.

     f.        Rights as a Shareholder.  A recipient of any Other Stock-based
          Award will have rights of a shareholder only at the time and to the
          extent, if any, specified by the Committee in the Other Stock-based
          Award Agreement. 

     g.        Deemed Dividend Payments; Deferrals.  Without limiting the right
          of the Committee to specify different terms, an Other Stock-based
          Award Agreement may require or permit the immediate payment, waiver,
          deferral, or investment of dividends or deemed dividends payable or
          deemed payable on Stock subject to the Award. 

     h.        Supplemental Grants.  The Company may in its sole discretion
          make a loan to the recipient of an Award hereunder, either on or
          after the date of grant of such Award.  Such loans may be made either
          in connection with the exercise of a Stock Option, a Stock
          Appreciation Right, or an Other Stock-based Award, in connection with

                                         Page 18

          the purchase of shares under any Award, or in connection with the
          payment of any federal income tax in respect of income recognized
          under an Award.  The Committee shall have full authority to decide
          whether to make a loan hereunder and to determine the amount, term,
          and provisions of any such loan, including the interest rate (which
          may be zero) charged in respect of any such loan, whether the loan is
          to be secured or unsecured, the terms on which the loan is to be
          repaid and the conditions, if any, under which it may be forgiven. 
          However, no loan hereunder shall provide or reimburse to the borrower
          the amount used by him for the payment of the par value of any shares
          of Common Stock issued, have a term (including extensions) exceeding
          ten years in duration, or be in an amount exceeding the total
          exercise or purchase price paid by the borrower under an Award or for
          related Stock under the Plan plus an amount equal to the cash payment
          permitted in the following paragraph. 

          The Committee may at any time authorize a cash payment, in respect of
          the grant or exercise of an Award under the Plan or the lapse or
          waiver of restrictions under an Award which shall not exceed the
          amount which would be required in order to pay in full the federal
          income tax due as a result of income recognized by the recipient
          under both the Award and such cash payment, in each case assuming
          that such income is taxed at the regular maximum marginal rate
          applicable to individuals under the Code as in effect at the time
          such income is includable in the recipient's income.  Subject to the
          foregoing, the Committee shall have complete authority to decide
          whether to make such cash payments in any case, to make provision for
          such payments either simultaneously with or after the grant of the
          associated Award, and to determine the amount of each such payment. 

SECTION 12.  Transfer, Leave of Absence, Etc.

     For purposes of the Plan, the following events shall not be deemed a
termination of employment:

     a.        a transfer to the employment of the Company from a Subsidiary or
          from the Company to a Subsidiary, or from one Subsidiary to another;
          or

     b.        an approved leave of absence for military service or sickness,
          or for any other purpose approved by the Company, if the employee's
          right to reemployment is guaranteed either by a statute or by
          contract or under the policy pursuant to which the leave of absence
          was granted or if the Committee otherwise so provides in writing.

          For purposes of Section 6(j), Section 8(a), Section 8(d), Section
          9(e), Section 9(f), Section 10(e) and Section 10(f), except as

                                       Page 19

          otherwise determined by the Committee an optionee employed as an
          employee by the Company and its Subsidiaries shall be treated as
          having incurred a termination of employment by or other service
          relationship with the Company and its Subsidiaries on the date he or
          she ceases to be an employee, whether or not he or she continues to
          provide services to the Company or its Subsidiaries on some other
          basis.

SECTION 13.   Amendments and Termination.

     The Board may at any time amend or discontinue the Plan and the Committee
may at any time amend or cancel any outstanding Award (or provide substitute
Awards at the same or reduced exercise or purchase price or with no exercise or
purchase price, but such price, if any, must satisfy the requirements which
would apply to the substitute or amended Award if it were then initially
granted under this Plan) for the purpose of satisfying changes in law or for
any other lawful purpose, but no such action shall adversely affect rights
under any outstanding Award without the holder's consent.  However, no such
amendment, unless approved by stockholders, shall be effective if it would
cause the Plan to fail to satisfy the incentive stock option requirements of
the Code or the requirements of Rule 16b-3 or any successor rule under the Act
as in effect on the date of such amendment.

SECTION 14.  Status of Plan.

     With respect to the portion of any Award which has not been exercised and
any payments in cash, stock, or other consideration not received by a
participant, a participant shall have no rights greater than those of a general
creditor of the Company unless the Committee shall otherwise expressly
determine in connection with any Award or Awards.  In its sole discretion, the
Committee may authorize the creation of trusts or other arrangements to meet
the Company's obligations to deliver Stock or make payments with respect to
awards hereunder, provided that the existence of such trusts or other
arrangements is consistent with the provision of the foregoing sentence.

SECTION 15.  General Provisions.

     a.        No Distribution; Compliance with Legal Requirements, etc.  The
          Committee may require each person acquiring shares pursuant to an
          Award to represent to and agree with the Company in writing that such
          person is acquiring the shares without a view to distribution
          thereof.

          No shares of Stock shall be issued pursuant to an Award until all
          applicable securities laws and other legal and stock exchange
          requirements have been satisfied.  The Committee may require the
          placing of such stop-orders and restrictive legends on certificates
          for Stock and Awards as it deems appropriate.

                                     Page 20

     b.        Other Compensation Arrangements; No Employment Rights.  Nothing
          contained in this Plan shall prevent the Board of Directors from
          adopting other or additional compensation arrangements, subject to
          stockholder approval if such approval is required; and such
          arrangements may be either generally applicable or applicable only in
          specific cases.  The adoption of the Plan does not confer upon any
          employee or other person any right to continued employment or the
          continuation of any service relationship with the Company or a
          Subsidiary, nor does it interfere in any way with the right of the
          Company or a Subsidiary to terminate the employment or other service
          relationship that may exist between it and any person.

     c.        Tax Withholding, etc.  Each participant shall, no later than the
          date as of which the value of an Award or of any Stock or other
          amounts received thereunder first becomes includable in the gross
          income of the participant for Federal income tax purposes, pay to the
          Company, or make arrangements satisfactory to the Committee regarding
          payment of, any Federal, state, or local taxes of any kind required
          by law to be withheld with respect to such income.  The Company and
          its Subsidiaries shall, to the extent permitted by law, have the
          right to deduct any such taxes from any payment of any kind otherwise
          due to the participant.


     d.        Cancellation of Awards.  The Committee may provide, with respect
          to any Award, that the Award shall be cancelled or rescinded and any
          associated shares forfeited, and that the participant be obligated to
          pay to the Company any gain received upon exercise or vesting, in the
          event that the participant competes with the Company or its
          Subsidiaries, discloses confidential information of the Company or
          its Subsidiaries, or otherwise is not in compliance with any
          provision of the Award, in each case on such terms and conditions as
          the Committee considers appropriate in the circumstances.

SECTION 16.  Effective Date of Plan.

     The Plan shall not become effective unless approved by the vote of the
holders of a majority of the shares of capital stock of the Company represented
at a meeting of stockholders.  Subject to such effectiveness, and to the
requirement that no Stock may be issued hereunder prior to such approval,
Options and other Awards may be granted hereunder on and after adoption of the
Plan by the Board.
