                  (i) to select the officers and other key employees of and
         consultants to the Corporation and its Subsidiaries and Affiliates to

<PAGE>   4

         Stock-Based Awards, or any combination thereof, are to be granted
         hereunder to one or more eligible employees;

                  (iii) to determine the number of shares to be covered by each
         such award granted hereunder;

                  (iv) to determine the terms and conditions, not inconsistent
         with the terms of the Plan, of any award granted hereunder (including,
         but not limited to, the share price and any restriction or limitation,
         or any vesting, acceleration of vesting or waiver of forfeiture
         restrictions regarding any Option or other award or the shares of
         Common Stock relating thereto, based in each case on such factors as
         the Committee shall determine, in its sole discretion) and to amend or
         waive any such terms and conditions to the extent permitted by Section
         10 hereof;

                  (v) to determine whether and under what circumstances an
         Option or Stock Appreciation Right may be settled in cash or Restricted
         Stock under Section 5(b)(xiii) hereof, instead of shares of Common
         Stock;

                  (vi) to determine whether, to what extent and under what
         circumstances Option grants or other awards under the Plan are to be
         made, and operate, on a tandem basis vis-a-vis other awards under the
         Plan, or on an additive basis;

                  (vii) to determine whether, to what extent and under what
         circumstances shares of Common Stock and other amounts payable with
         respect to an award under this Plan shall be deferred either
         automatically or at the election of the participant (including
         providing for and determining the amount (if any) of any deemed
         earnings on any deferred amount during any deferral period); and

         withholding requirements in shares of Common Stock.

         The Committee shall have the authority to adopt, alter and repeal such
rules, guidelines and practices governing the Plan as it shall, from time to
time, deem advisable; to interpret the terms and provisions of the Plan and any
award issued under the Plan (and any agreements relating thereto); and to
otherwise supervise the administration of the Plan.

         All decisions made by the Committee pursuant to the provisions of the
Plan shall be made in the Committee's sole discretion and shall be final and
binding on all persons, including the Corporation and Plan participants.

 SECTION 3. SHARES OF COMMON STOCK SUBJECT TO PLAN.

         (a) SHARES OF COMMON STOCK RESERVED UNDER PLAN. The aggregate number of
shares of Common Stock reserved and available for distribution under the Plan
shall be 3,000,000 shares. Such shares of Common Stock may consist, in whole or
in part, of authorized and unissued shares or treasury shares. The aggregate
number of shares of Common Stock that may be granted to any individual pursuant
to any award under the Plan or with respect to which any awards are made shall
be 500,000, or up to 500,000 in any one year.

         If any Option or Stock Appreciation Right expires or is forfeited
without exercise, or if any shares of Common Stock that are subject to any
Restricted Stock or Other Stock-Based Award granted hereunder are forfeited
prior to the payment of any dividends, if applicable, with respect to such
shares of Common Stock, such shares shall again be available for distribution in
connection with future awards under the Plan. If dividends have been paid to the
grantee with respect to the shares of Common Stock subject to such forfeited
award, such shares shall not be available for distribution in connection with
future awards under the Plan.

         (b) ADJUSTMENT IN CERTAIN EVENTS. In the event of any merger,
reorganization, consolidation, recapitalization, extraordinary cash dividend,
stock dividend, stock split or other change in corporate structure affecting the
Common Stock (a "Capital Transaction"), a substitution or adjustment will be
made in the aggregate number of shares reserved for issuance under the Plan, the
number that may be granted to any individual in any year or over the life of the
Plan and the number and price (if applicable) of shares subject to outstanding
awards granted under the Plan, so as to provide each holder of an award under
this Plan with the same rights on exercise or distribution of the benefits of
such award that such holder would have received if such holder had exercised or
received a distribution of the benefits of such award immediately prior to the
occurrence of such Capital Transaction; provided, however, that the number of
shares subject to any award shall always be a whole number. In the event of any
dispute as to any substitution or adjustment made under this Section 3(b), the
decision of the Committee shall be final and binding on all persons, including
the Corporation and Plan participants.

SECTION 4.  ELIGIBILITY.

         Officers and other key employees of and consultants to the Corporation
and its Subsidiaries and Affiliates (but excluding members of the Committee and
any person who serves only as a director) who are responsible for or contribute
to the management, growth or profitability of the business of the Corporation
and its Subsidiaries and Affiliates are eligible to be granted awards under the
Plan. Incentive Stock Options may only be granted to persons who are employees
of the Corporation or a Subsidiary of the Corporation.

SECTION 5.  OPTIONS.

         (a) ADMINISTRATION. Options may be granted alone, in addition to or in
tandem with other awards granted under the Plan. Any Option granted under the
Plan shall be in such form as the Committee may from time to time approve.

         Options granted under the Plan may be of two types: (i) Incentive Stock
Options and (ii) Non-Qualified Stock Options. Incentive Stock Options may be
granted only to individuals who are employees of the Corporation or any
Subsidiary of the Corporation.

         The Committee shall have the authority to grant to any optionee
(subject to the limitation set forth in the paragraph above) Incentive Stock
Options, Non-Qualified Stock Options, or both types of Options (in each case
with or without Stock Appreciation Rights).

         (b) TERMS AND CONDITIONS. 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.

                  (i) Option Price. The option price per share of Common Stock
         purchasable under an Option shall be determined by the Committee at the
         time of grant but shall be not less than 100% (or, in the case of any
         employee who owns stock possessing more than 10% of the total combined
         voting power of all classes of stock of the Corporation or of any of
         its subsidiary or parent corporations, not less than 110%) of the Fair
         Market Value of the Common Stock at grant, in the case of Incentive
         Stock Options, and not less than 50% of the Fair Market Value of the
         Common Stock at grant, in the case of Non-Qualified Stock Options.

                  (ii) Option Term. The term of each Option shall be fixed by
         the Committee, but no Incentive Stock Option shall be exercisable more
         than ten years (or, in the case of an employee who owns stock
         possessing more than 10% of the total combined voting power of all
         classes of stock of the Corporation or any of its subsidiary or parent
         corporations, more than five years) after the date the Option is
         granted.

                  (iii) Exercisability. Options shall be exercisable at such
         time or times and subject to such terms and conditions as shall be
         determined by the Committee at or after grant; provided, however, that
         except as provided in Section 5(b)(vii), (viii) and (ix) hereof and
         Section 9 hereof, unless otherwise determined by the Committee at or
         after grant, no Option shall be exercisable prior to the first
         anniversary date of the granting of the Option. The Committee may
         provide that an Option shall vest over a period of future service at a
         rate specified at the time of grant, or that the Option is


                                       6

<PAGE>   7

         exercisable only in installments. If the Committee provides, in its
         sole discretion, that any Option is exercisable only in installments,
         the Committee may waive such installment exercise provisions at any
         time at or after grant in whole or in part, based on such factors as
         the Committee shall determine, in its sole discretion. The Committee
         may establish performance conditions or other conditions to the
         exercisability of any Options, as determined by the Committee in its
         sole discretion, which conditions may be waived by the Committee in its
         sole discretion.

                  (iv) Method of Exercise. Subject to whatever installment or
         other exercise restrictions apply under Section 5(b)(iii) hereof,
         Options may be exercised in whole or in part at any time during the
         option period, by giving written notice of exercise to the Corporation
         specifying the number of shares to be purchased.

                  Such notice shall be accompanied by payment in full of the
         purchase price, either by check, note or such other instrument as the
         Committee may accept. As determined by the Committee, in its sole
         discretion, at or (except in the case of an Incentive Stock Option)
         after grant, payment in full or in part may also be made in the form of
         unrestricted shares of Common Stock already owned by the optionee or,
         in the case of the exercise of a Non-Qualified Stock Option, Common
         Stock or Restricted Stock subject to an award hereunder (based in each
         case, on the Fair Market Value of the Common Stock on the date the
         option is exercised, as determined by the Committee). If payment of the
         exercise price is made in part or in full with shares of Common Stock,
         the Committee may (subject to the availability of additional shares
         reserved for issuance under Section 3 above) award to the optionee a
         new Option to replace the shares of Common Stock which were
         surrendered.

                  If payment of the option exercise price of a Non-Qualified
         Stock Option is made in whole or in part in the form of Restricted
         Stock, the Common Stock received upon exercise shall be restricted in
         accordance with the original terms of the Restricted Stock award in
         question, and any additional shares of Common Stock received upon the
         exercise shall be subject to the same forfeiture restrictions, unless
         otherwise determined by the Committee, in its sole discretion, at or
         after grant.

                  No shares of Common Stock shall be issued until full payment
         therefor has been made. An optionee shall generally have the rights to
         dividends or other rights of a shareholder with respect to shares
         subject to the Option when the optionee has given written notice of
         exercise, has paid in full for such shares, and, if requested, has
         given the representation described in Section 12(a) hereof.

                  (v) Non-Transferability of Incentive Stock Options.
         Notwithstanding any other provision of this Plan, no Incentive Stock
         Option shall be transferable by the optionee otherwise than by will or
         by the laws of descent and distribution, and all


                                       7

<PAGE>   8

         Incentive Stock Options shall be exercisable, during the optionee's
         lifetime, only by the optionee.

                  (vi) Bonus for Taxes. In the case of a Non-Qualified Stock
         Option, the Committee in its discretion may award at the time of grant
         or thereafter the right to receive upon exercise of such Option a cash
         bonus calculated to pay part or all of the federal and state, if any,
         income tax incurred by the optionee upon such exercise.

                  (vii) Termination by Death. Subject to Section 5(b)(xi)
         hereof, if an optionee's employment by the Corporation and any
         Subsidiary or (except in the case of an Incentive Stock Option)
         Affiliate terminates by reason of death, any Option held by such
         optionee may thereafter be exercised, to the extent such Option was
         exercisable at the time of death or (except in the case of an Incentive
         Stock Option) on such accelerated basis as the Committee may determine
         at or after grant (or except in the case of an Incentive Stock Option,
         as may be determined in accordance with procedures established by the
         Committee) by the legal representative of the estate or by the legatee
         of the optionee under the will of the optionee, for a period of one
         year (or such shorter period as the Committee may specify at grant)
         from the date of such death or until the expiration of the stated term
         of such Option, whichever period is the shorter.

                  (viii) Termination by Reason of Disability. Subject to Section
         5(b)(xi) hereof, if an optionee's employment by the Corporation and any
         Subsidiary or (except in the case of an Incentive Stock Option)
         Affiliate terminates by reason of Disability, any Option held by such
         optionee may thereafter be exercised by the optionee, to the extent it
         was exercisable at the time of termination or (except in the case of an
         Incentive Stock Option) on such accelerated basis as the Committee may
         determine at or after grant (or, except in the case of an Incentive
         Stock Option, as may be determined in accordance with procedures
         established by the Committee), for a period of (A) three years (or such
         shorter period as the Committee may specify at grant) from the date of
         such termination of employment or until the expiration of the stated
         term of such Option, whichever period is the shorter, in the case of a
         Non-Qualified Stock Option and (B) one year from the date of
         termination of employment or until the expiration of the stated term of
         such Option, whichever period is shorter, in the case of an Incentive
         Stock Option; provided, however, that, if the optionee dies within the
         period specified in clause (A) above (or such other period as the
         Committee shall specify at grant), any unexercised Non-Qualified Stock
         Option held by such optionee shall thereafter be exercisable to the
         extent to which it was exercisable at the time of death for a period of
         twelve months from the date of such death or until the expiration of
         the stated term of such Option, whichever period is the shorter. In the
         event of termination of employment by reason of Disability, if an
         Incentive Stock Option is exercised after the expiration of the
         exercise period applicable to Incentive Stock Options, but before the
         expiration of any period that would apply if such Stock Option


                                       8

<PAGE>   9

         were a Non-Qualified Stock Option, such Stock Option will thereafter be
         treated as a Non-Qualified Stock Option.

                  (ix) Termination by Reason of Retirement. Subject to Section
         5(b)(xi) hereof, if an optionee's employment by the Corporation and any
         Subsidiary or (except in the case of an Incentive Stock Option)
         Affiliate terminates by reason of Normal or Early Retirement, any
         Option held by such optionee may thereafter be exercised by the
         optionee, to the extent it was exercisable at the time of such
         Retirement or (except in the case of an Incentive Stock Option) on such
         accelerated basis as the Committee may determine at or after grant (or,
         except in the case of an Incentive Stock Option, as may be determined
         in accordance with procedures established by the Committee), for a
         period of (A) three years (or such shorter period as the Committee may
         specify at grant) from the date of such termination of employment or
         the expiration of the stated term of such Option, whichever period is
         the shorter, in the case of a Non-Qualified Stock Option and (B) three
         months from the date of such termination of employment or the
         expiration of the stated term of such Option, whichever period is the
         shorter, in the event of an Incentive Stock Option; provided, however,
         that, if the optionee dies within the period specified in clause (A)
         above (or such shorter period as the Committee may specify at grant),
         any unexercised Non-Qualified Stock Option held by such optionee shall
         thereafter be exercisable, to the extent to which it was exercisable at
         the time of death, for a period of 12 months from the date of such
         death or until the expiration of the stated term of such Option,
         whichever period is the shorter. In the event of termination of
         employment by reason of Retirement, if an Incentive Stock Option is
         exercised after the expiration of the exercise period applicable to
         Incentive Stock Options, but before the expiration of the period that
         would apply if such Stock Option were a Non-Qualified Stock Option, the
         option will thereafter be treated as a Non-Qualified Stock Option.

                  (x) Other Termination. Unless otherwise determined by the
         Committee (or pursuant to procedures established by the Committee) at
         or (except in the case of an Incentive Stock Option) after grant, if an
         optionee's employment by the Corporation and any Subsidiary or (except
         in the case of an Incentive Stock Option) Affiliate is involuntarily
         terminated for any reason other than death, Disability or Normal or
         Early Retirement, the Option shall thereupon terminate, except that
         such Option may be exercised, to the extent otherwise then exercisable,
         for the lesser of three months or the balance of such Option's term if
         the involuntary termination is without Cause. For purposes of this
         Plan, "Cause" means (A) a felony conviction of a participant or the
         failure of a participant to contest prosecution for a felony, or (B) a
         participant's willful misconduct or dishonesty, which is directly and
         materially harmful to the business or reputation of the Corporation or
         any Subsidiary or Affiliate. If an optionee voluntarily terminates
         employment with the Corporation and any Subsidiary or (except in the
         case of an Incentive Stock Option) Affiliate (except for Disability,
         Normal or Early Retirement), the Option shall thereupon terminate;
         provided, however, that the


                                       9

         Committee at grant or (except in the case of an Incentive Stock Option)
         thereafter may extend the exercise period in this situation for the
         lesser of three months or the balance of such Option's term.

                  (xi) Incentive Stock Options. 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 under the Plan be so exercised, so as
         to disqualify the Plan under Section 422 of the Code, or, without the
         consent of the optionee(s) affected, to disqualify any Incentive Stock
         Option under such Section 422.

                  No Incentive Stock Option shall be granted to any participant
         under the Plan if such grant would cause the aggregate Fair Market
         Value (as of the date the Incentive Stock Option is granted) of the
         shares of Common Stock with respect to which all Incentive Stock
         Options are exercisable for the first time by such optionee during any
         calendar year (under all such plans of the Corporation and any
         Subsidiary) to exceed $100,000.

                  To the extent permitted under Section 422 of the Code or the
         applicable regulations thereunder or any applicable Internal Revenue
         Service pronouncement:


                               a. if the exercise of an Incentive Stock Option
                  is accelerated by reason of a Change in Control, any portion
                  of such option that is not exercisable as an "incentive stock
                  option" under Section 422 of the Code by reason of the
                  $100,000 limitation contained in Section 422(d) of the Code
                  shall be treated as a Non-Qualified Stock Option;

                               b. if for any other reason the portion of any
                  Incentive Stock Option that is otherwise exercisable without
                  regard to the $100,000 limitation contained in Section 422(d)
                  of the Code, is greater than the portion of such option that
                  is immediately exercisable as an "incentive stock option"
                  under Section 422 of the Code, such excess shall be treated as
                  a Non-Qualified Stock Option; and

                               c. the Committee shall have the right, with the
                  consent of the optionee, to treat an Incentive Stock Option
                  that cannot be exercised, for any other reason, as an
                  "incentive stock option" under Section 422 of the Code as a
                  Non-Qualified Stock Option.

                  (xii) Performance and Other Conditions. The Committee may
         condition the exercise of any Option upon the attainment of specified
         performance goals or other factors as the Committee may determine, in
         its sole discretion. Unless specifically provided in the option
         agreement, any such conditional Option shall vest immediately


                                       10

<PAGE>   11

         prior to its expiration if the conditions to exercise have not
         theretofore been satisfied. The shares of Common Stock acquired
         pursuant to any conditional Option shall not be transferable by an
         optionee subject to Section 16(a) of the Exchange Act within six months
         of the date such Option first becomes exercisable.

                  (xiii) Settlement Provisions. If the option agreement so
         provides at grant or (except in the case of an Incentive Stock Option)
         is amended after grant and prior to exercise to so provide (with the
         optionee's consent), the Committee may require that all or part of the
         shares to be issued with respect to the spread value of an exercised
         Option take the form of Restricted Stock, which shall be valued on the
         date of exercise on the basis of the Fair Market Value (as determined
         by the Committee) of such Restricted Stock determined without regards
         to the forfeiture restrictions involved.


SECTION 6.  STOCK APPRECIATION RIGHTS.

         (a) GRANT AND EXERCISE. Stock Appreciation Rights may be granted alone
or in conjunction with all or part of any Option granted under the Plan. In the
case of a Non-Qualified Stock Option, such rights may be granted either at or
after the time of the grant of such Option. In the case of an Incentive Stock
Option, such rights may be granted only at the time of the grant of such Option.

         A Stock Appreciation Right or applicable portion thereof granted with
respect to a given Option shall terminate and no longer be exercisable upon the
termination or exercise of the related Option, subject to such provisions as the
Committee may specify at grant where a Stock Appreciation Right is granted with
respect to less than the full number of shares covered by a related Option.

         A Stock Appreciation Right may be exercised by the grantee, subject to
Section 6(b) hereof, in accordance with the procedures established by the
Committee for such purpose. Upon such exercise, the grantee shall be entitled to
receive an amount determined in the manner prescribed in Section 6(b) hereof.
Options relating to exercised Stock Appreciation Rights shall no longer be
exercisable to the extent that the related Stock Appreciation Rights have been
exercised.

         (b) TERMS AND CONDITIONS. Stock Appreciation Rights shall be subject to
such terms and conditions, not inconsistent with the provisions of the Plan, as
shall be determined from time to time by the Committee, including the following:

                  (i) Exercise Provisions for Tandem Grants. A Stock
         Appreciation Right granted in conjunction with all or part of any
         Option shall be exercisable only at such time or times and to the
         extent that the Option to which it relates shall be exercisable in
         accordance with the provisions of Section 5 and this Section 6 of the
         Plan; provided,


                                       11

<PAGE>   12

         however, that any Stock Appreciation Right granted to a grantee subject
         to Section 16(a) of the Exchange Act shall be subject to the further
         limitations set forth in Section 6(b)(v) and, if applicable, Section
         6(b)(vi) below.

                  (ii) Payment on Exercise. Upon the exercise of a Stock
         Appreciation Right, a grantee shall be entitled to receive an amount in
         cash or shares of Common Stock (or a combination of cash and shares of
         Common Stock) equal in value to the excess of the Fair Market Value of
         one share of Common Stock over the price per share specified in the
         Stock Appreciation Right or related Option multiplied by the number of
         shares in respect of which the Stock Appreciation Right shall have been
         exercised, with the Committee having the right to determine the form of
         payment.

                  (iii) Use of Authorized Shares. Upon the exercise of a Stock
         Appreciation Right, any shares of Common Stock issued thereunder or
         with respect to which a cash payment was made shall be deemed to have
         been issued for the purpose of the limitation set forth in Section 3 of
         the Plan on the number of shares of Common Stock to be issued under the
         Plan.

                  (iv) Payment based on Change in Control Price. Unless
         otherwise determined by the Committee at grant, in the event of a
         Change in Control or a Potential Change in Control, the amount to be
         paid upon the exercise of a Stock Appreciation Right shall be based on
         the Change in Control Price, subject to such terms and conditions as
         the Committee may specify at grant.

                  (v) Restrictions on Exercise by Persons Subject to Section
         16(a). The exercise of Stock Appreciation Rights held by grantees who
         are subject to Section 16(a) of the Exchange Act shall comply with Rule
         16b-3(e) thereunder. In particular, such Stock Appreciation Rights
         shall be exercisable only pursuant an irrevocable election made at
         least six months prior to the date of exercise or within the applicable
         ten business day "window" periods specified in Rule 16b-3(e)(3). Stock
         Appreciation Rights held by grantees who are subject to Section 16(a)
         of the Exchange Act shall not be exercisable for the first six months
         after the date of grant.

                  (vi) Performance and Other Conditions. The Committee may
         condition the exercise of any Stock Appreciation Right upon the
         attainment of specified performance goals or other factors as the
         Committee may determine, in its sole discretion. Unless specifically
         provided in the applicable award agreement, any such conditional Stock
         Appreciation Right shall vest immediately prior to its expiration, if
         the conditions to exercise have not theretofore been satisfied. A
         conditional Stock Appreciation Right held by a grantee subject to
         Section 16(a) of the Exchange Act shall not be exercisable until the
         expiration of six months following the satisfaction of the condition
         giving rise to such Stock Appreciation Right.

SECTION 7.  RESTRICTED STOCK.

         (a) ADMINISTRATION. Shares of Restricted Stock may be issued either
alone, in addition to or in tandem with other awards granted under the Plan. The
Committee shall determine the eligible persons to whom, and the time or times at
which, grants of Restricted Stock will be made, the number of shares of
Restricted Stock to be awarded to any person, the price (if any) to be paid by
the recipient of Restricted Stock (subject to Section 7(b) hereof), the time or
times within which such awards may be subject to forfeiture, and the other
terms, restrictions and conditions of the awards in addition to those set forth
in Section 7(c) hereof.

         The Committee may condition the grant or vesting of Restricted Stock
upon the attainment of specified performance goals or other factors as the
Committee may determine, in its sole discretion.

         (b) AWARDS AND CERTIFICATES. The prospective recipient of a Restricted
Stock award shall not have any rights with respect to such award, unless and
until such recipient has executed an agreement evidencing the award and has
delivered a fully executed copy thereof to the Corporation, and has otherwise
complied with the applicable terms and conditions of such award.

                  (i) Purchase Price. The purchase price for shares of
         Restricted Stock shall be established by the Committee and may be zero.

                  (ii) Acceptance of Awards. Awards of Restricted Stock must be
         accepted within a period of 60 days (or such shorter period as the
         Committee may specify at grant) after the award date, by executing a
         Restricted Stock award agreement and paying whatever price (if any) is
         required under Section 7(b)(i) hereof.

                  (iii) Stock Certificates. Each participant receiving a
         Restricted Stock award shall be issued a stock certificate in respect
         of such shares of Restricted Stock. Such certificate shall be
         registered in the name of such participant, and shall bear an
         appropriate legend referring to the terms, conditions, and restrictions
         applicable to such award.

                  (iv) Custody of Stock Certificates. The Committee shall
         require that the stock certificates evidencing such shares be held in
         custody by the Corporation until the restrictions thereon shall have
         lapsed, and that, as a condition of any Restricted Stock award, the
         participant shall have delivered a stock power, endorsed in blank,
         relating to the shares of Common Stock covered by such award.

         (c) RESTRICTIONS AND CONDITIONS. The shares of Restricted Stock awarded
pursuant to this Section 7 shall be subject to the following restrictions and
conditions:


                                       13


<PAGE>   14

                  (i) Restriction Period. Subject to the provisions of this Plan
         and the award agreement, during a period set by the Committee
         commencing with the date of such award (the "Restriction Period"), the
         participant shall not be permitted to sell, transfer, pledge, assign or
         otherwise encumber shares of Restricted Stock awarded under the Plan.
         Within these limits, the Committee, in its sole discretion, may provide
         for the lapse of such restrictions in installments and may accelerate
         or waive such restrictions in whole or in part, based on service,
         performance or other factors or criteria as the Committee may
         determine, in its sole discretion.

                  (ii) Dividends. Except as provided in this paragraph (ii),
         Section 7(c)(i) hereof and the award agreement, the participant shall
         have, with respect to the shares of Restricted Stock, all of the rights
         of a shareholder of the Corporation, including the right to vote the
         shares, and the right to receive any cash dividends. The Committee, in
         its sole discretion, as determined at the time of award, may permit or
         require the payment of cash dividends to be deferred and, if the
         Committee so determines, reinvested, subject to Section 12(e) hereof,
         in additional Restricted Stock to the extent shares are available under
         Section 3 hereof, or otherwise reinvested. Pursuant to Section 3
         hereof, stock dividends issued with respect to Restricted Stock shall
         be treated as additional shares of Restricted Stock that are subject to
         the same restrictions and other terms and conditions that apply to the
         shares of Restricted Stock with respect to which such dividends are
         issued.

                  (iii) Vesting and Forfeiture. Subject to the applicable
         provisions of the award agreement and this Section 7, upon termination
         of a participant's employment with the Corporation and any Subsidiary
         or Affiliate for any reason during the Restriction Period, all shares
         still subject to restriction will vest, or be forfeited, in accordance
         with the terms and conditions established by the Committee at or after
         grant.

                  (iv) Delivery of Shares on Termination of Restriction Period.
         If and when the Restriction Period expires without a prior forfeiture
         of the Restricted Stock subject to such Restriction Period,
         certificates for an appropriate number of unrestricted shares shall be
         delivered to the participant promptly.


SECTION 8.  OTHER STOCK-BASED AWARDS.

         (a) ADMINISTRATION. Other Stock-Based Awards valued by reference to
shares of Common Stock may be granted either alone or in addition to or in
tandem with Options, Stock Appreciation Rights or Restricted Stock granted under
the Plan; provided that no such Other Stock-Based Awards may be granted in
tandem with Incentive Stock Options if that would cause such Incentive Stock
Options not to qualify as "incentive stock options" pursuant to Section 422 of
the Code.


                                       14


<PAGE>   15

         Subject to the provisions of the Plan, the Committee shall have
authority to determine the persons to whom and the time or times at which such
awards shall be made, the number of shares of Common Stock to be awarded
pursuant to such awards, and all other conditions of the awards. The Committee
may also provide for the grant of shares of Common Stock upon the completion of
a specified performance period.

         The provisions of Other Stock-Based Awards need not be the same with
respect to each recipient.

         (b) TERMS AND CONDITIONS. Other Stock-Based Awards made pursuant to
this Section 8 shall be subject to the following terms and conditions:

                  (i) Restriction on Transfer. Subject to the provisions of this
         Plan and the award agreement referred to in Section 8(b)(v) below,
         shares subject to awards under this Section 8 may not be sold,
         assigned, transferred, pledged or otherwise encumbered prior to the
         date on which the shares are issued, or, if later, the date on which
         any applicable restriction, performance or deferral period lapses.

                  (ii) Dividends and Interest. Subject to the provisions of this
         Plan and the award agreement and unless otherwise determined by the
         Committee at grant, the recipient of an award under this Section 8
         shall be entitled to receive, currently or on a deferred basis,
         interest or dividends or interest or dividend equivalents with respect
         to the number of shares covered by the award, as determined at the time
         of the award by the Committee, in its sole discretion, and the
         Committee may provide that such amounts (if any) shall be deemed to
         have been reinvested in additional shares of Common Stock or otherwise
         reinvested.

                  (iii) Vesting and Forfeiture. Any award under this Section 8
         and any shares of Common Stock covered by any such award shall vest or
         be forfeited to the extent so provided in the award agreement, as
         determined by the Committee, in its sole discretion.

                  (iv) Waiver of Vesting or Forfeiture Provisions. In the event
         of the participant's Retirement, Disability or death, or in cases of
         special circumstances, the Committee may, in its sole discretion, waive
         in whole or in part any or all of the remaining limitations imposed
         hereunder (if any) with respect to any or all of an award under this
         Section 8.

                  (v) Awards Agreements. Each award under this Section 8 shall
         be confirmed by, and subject to the terms of, an agreement between the
         Corporation and the participant.


                                       15


<PAGE>   16

                  (vi) Purchase Price. Shares of Common Stock (including
         securities convertible into shares of Common Stock) issued on a bonus
         basis under this Section 8 may be issued for no cash consideration. The
         purchase price of shares of Common Stock (including securities
         convertible into shares of Common Stock) purchased pursuant to a
         purchase right awarded under this Section 8 shall be determined by the
         Committee in its sole discretion on the date of grant.


SECTION 9.  CHANGE IN CONTROL PROVISIONS.

         (a) IMPACT OF EVENT. In the event of a Change in Control or Potential
Change in Control, the following acceleration and valuation provisions shall
apply if so determined by the Committee in its sole discretion:

                  (i) Acceleration of Vesting. Any Stock Appreciation Rights and
         any Option awarded under the Plan not previously exercisable and vested
         shall become fully exercisable and vested; provided, however, that
         Stock Appreciation Rights held by persons subject to Section 16(a)
         under the Exchange Act shall not become exercisable until six months
         after the date of grant.

                  (ii) Lapse of Other Restrictions. The restrictions and
         deferral limitations applicable to any Restricted Stock and Other
         Stock-Based Awards, in each case to the extent not already vested under
         the Plan, shall lapse and such shares and awards shall be deemed fully
         vested.

                  (iii) Cash-Out Provisions. Except as otherwise provided in
         Section 9(a)(iv) below, the value of all outstanding Options, Stock
         Appreciation Rights, Restricted Stock and Other Stock-Based Awards
         shall, unless otherwise determined by the Committee in its sole
         discretion at or (except in the case of an Incentive Stock Option)
         after grant but prior to any Change in Control, be cashed out on the
         basis of the Change in Control Price as of the date such Change in
         Control or such Potential Change in Control is determined to have
         occurred or such other date as the Committee may determine prior to the
         Change in Control.

                  (iv) Cash-Out Provisions for Statutory Insiders. In the case
         of any Options, Stock Appreciation Rights, Restricted Stock and Other
         Stock-Based Awards held by any person subject to Section 16(a) of the
         Exchange Act, the value of all such Options, Stock Appreciation Rights,
         Restricted Stock or Other Stock-Based Awards, in each case to the
         extent that they have been held for at least six months, shall be
         cashed out on the basis of the Change in Control Price as of the date
         of such Change in Control or such Potential Change in Control is
         determined to have occurred. The Committee shall have the right (A) to
         cause any right to receive the Change in Control Price to be canceled
         with respect to all or any grantee(s) who are subject to Section 16(a)
         of the


                                       16

<PAGE>   17

         Exchange Act if payment of the Change in Control Price to such
         grantee(s) would cause liability under Section 16 of the Exchange Act,
         and (B) to determine whether the change in Control Price shall be paid
         in cash or in shares of capital stock (including the capital stock of
         any acquiring corporation) to grantees who are subject to Section 16(a)
         of the Exchange Act.

         (b) DEFINITION OF CHANGE IN CONTROL. A "Change in Control" means the
happening of any of the following:

                  (i) any person or entity, including a "group" as defined in
         Section 13(d)(3) of the Exchange Act, other than the Corporation or a
         wholly-owned subsidiary thereof or any employee benefit plan of the
         Corporation or any of its Subsidiaries, becomes the beneficial owner of
         the Corporation's securities having 20% or more of the combined voting
         power of the then outstanding securities of the Corporation that may be
         cast for the election of directors of the Corporation (other than as a
         result of an issuance of securities initiated by the Corporation in the
         ordinary course of business); or

                  (ii) as the result of, or in connection with, any cash tender
         or exchange offer, merger or other business combination, sale of assets
         or contested election, or any combination of the foregoing
         transactions, less than a majority of the combined voting power of the
         then outstanding securities of the Corporation or any successor
         corporation or entity entitled to vote generally in the election of the
         directors of the Corporation or such other corporation or entity after
         such transaction are held in the aggregate by the holders of the
         Corporation's securities entitled to vote generally in the election of
         directors of the Corporation immediately prior to such transaction; or

                  (iii) during any period of two consecutive years, individuals
         who at the beginning of such period constitute the Board cease for any
         reason to constitute at least a majority thereof, unless the election,
         or the nomination for election by the Corporation's shareholders, of
         each director of the Corporation first elected during such period was
         approved by a vote of at least two-thirds of the directors of the
         Corporation then still in office who were directors of the Corporation
         at the beginning of such period.

         (c) DEFINITION OF POTENTIAL CHANGE IN CONTROL. A "Potential Change in
Control" means the happening of any one of the following:

                  (i) The approval by shareholders of an agreement by the
         Corporation, the consummation of which would result in a Change in
         Control of the Corporation; or

                  (ii) The acquisition of beneficial ownership, directly or
         indirectly, by any entity, person or group (other than the Corporation
         or a Subsidiary or any Corporation employee benefit plan (including any
         trustee of such plan acting as such trustee)) of


                                       17

         securities of the Corporation representing 10% or more of the combined
         voting power of the Corporation's outstanding securities and the
         adoption by the Committee of a resolution to the effect that a
         Potential Change in Control of the Corporation has occurred for
         purposes of this Plan.

         (d) CHANGE IN CONTROL PRICE. The "Change in Control Price" means the
highest price per share paid in any transaction reported on The Nasdaq Stock
Market's National Market or such other exchange or market as is the principal
trading market for the Common Stock, or paid or offered in any bona fide
transaction related to a Change in Control or Potential Change in Control of the
Corporation at any time during the 60 day period immediately preceding the
occurrence of the Change in Control (or, where applicable, the occurrence of the
Potential Change in Control event), in each case as determined by the Committee
except that, in the case of Incentive Stock Options and Stock Appreciation
Rights relating to Incentive Stock Options, such price shall be based only on
transactions reported for the date on which the optionee exercises such
Incentive Stock Option or Stock Appreciation Rights or, where applicable, the
date on which a cash out occurs under Section 9(a)(iii) or (iv) hereof.

SECTION 10.  AMENDMENTS AND TERMINATION.

         The Board may amend, alter, or discontinue the Plan, but no amendment,
alteration, or discontinuation shall be made which would impair the rights of an
optionee or participant under an Option, Stock Appreciation Right, Restricted
Stock award or Other Stock-Based Award theretofore granted, without the
optionee's or participant's consent. In addition, no amendment or alteration
shall be made without the approval of the Corporation's shareholders, if such
amendment or alteration would:

                  (a) except as provided in Section 3(b) of the Plan, increase
         the total number of shares of Common Stock reserved for the purpose of
         the Plan;

                  (b) materially increase the benefits accruing to participants
         under the Plan; or

                  (c) materially modify the requirements as to eligibility for
         participation in the Plan.

         The Committee may amend the terms of any Option or other award
theretofore granted, prospectively or retroactively, but, subject to Section
3(b) above, no such amendment shall impair the rights of any holder without the
holder's consent. The Committee may also substitute new Options for previously
granted Options (on a one for one or other basis), including previously granted
Options having higher option exercise prices.

         Subject to the above provisions, the Board shall have broad authority
to amend the Plan to take into account changes in applicable securities and tax
laws and accounting rules, as well as other developments.

SECTION 11.  UNFUNDED STATUS OF PLAN.

         The Plan is intended to constitute an "unfunded" plan for incentive and
deferred compensation. With respect to any payments not yet made to a
participant or optionee by the Corporation, nothing contained herein shall give
any such participant or optionee any rights that are greater than those of a
general creditor of the Corporation. In its sole discretion, the Committee may
authorize the creation of trusts or other arrangements to meet the obligations
created under the Plan to deliver shares of Common Stock or payments in lieu of
or with respect to awards hereunder; provided, however, that, unless the
Committee otherwise determines with the consent of the affected participant, the
existence of such trusts or other arrangements is consistent with the "unfunded"
status of the Plan.


SECTION 12.  GENERAL PROVISIONS.

         (a) SECURITIES LAW RESTRICTIONS. The Committee may require each person
purchasing shares of Common Stock pursuant to an Option or other award under the
Plan to represent to and agree with the Corporation in writing that the optionee
or participant is acquiring the shares without a view to distribution thereof.
The certificates for such shares may include any legend which the Committee
deems appropriate to reflect any restrictions on transfer.

         All certificates for shares of Common Stock or other securities
delivered under the Plan shall be subject to such stock-transfer orders and
other restrictions as the Committee may deem advisable under the rules,
regulations, and other requirements of the Commission, any stock exchange upon
which the Common Stock is then listed, and any applicable Federal or state
securities law, and the Committee may cause a legend or legends to be put on any
such certificates to make appropriate reference to such restrictions.

         (b) OTHER COMPENSATION ARRANGEMENTS. Nothing contained in this Plan
shall prevent the Board from adopting other or additional compensation
arrangements, subject to shareholder approval if such approval is required; and
such arrangements may be either generally applicable or applicable only in
specific cases.

         (c) NO RIGHT TO CONTINUED EMPLOYMENT. The adoption of the Plan shall
not confer upon any employee of the Corporation or any Subsidiary or Affiliate
any right to continued employment with the Corporation or a Subsidiary or
Affiliate, as the case may be, nor shall it interfere in any way with the right
of the Corporation or a Subsidiary or Affiliate to terminate the employment of
any of its employees at any time.

         (d) WITHHOLDING. No later than the date as of which an amount first
becomes includible in the gross income of the participant for Federal income tax
purposes with respect to any award under the Plan, the participant shall pay to
the Corporation, or make arrangements satisfactory to the Committee regarding
the payment of, any Federal, state, or local taxes of any kind required by law
to be withheld with respect to such amount. The Committee may require
withholding obligations to be settled with shares of Common Stock, including
shares of Common Stock that are part of the award that gives rise to the
withholding requirement. The obligations of the Corporation under the Plan shall
be conditional on such payment or arrangements and the Corporation and its
Subsidiaries or Affiliates 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.

         (e) DIVIDENDS. The actual or deemed reinvestment of dividends or
dividend equivalents in additional Restricted Stock (or other types of Plan
awards) at the time of any dividend payment shall only be permissible if
sufficient shares of Common Stock are available under Section 3 hereof for such
reinvestment (taking into account then outstanding Options and other Plan
awards).

         (f) RESTRICTIONS ON TRANSFER. Unless determined otherwise by the
Committee, in addition to any other restrictions on transfer that may be
applicable under the terms of this Plan or the applicable award agreement, no
Option, Stock Appreciation Right, Restricted Stock award, or Other Stock-Based
Award or other right issued under this Plan is transferable by the participant
other than by will or the laws of descent and distribution or pursuant to a
domestic relations order as defined under the Code or Title I of the Employee
Retirement Income Security Act of 1974, as amended. The designation of a
beneficiary will not constitute a transfer. If the Committee makes a
Non-Qualified Stock Option (including any currently outstanding Non-Qualified
Stock Option) transferable, such Non-Qualified Stock Option shall contain such
additional terms and conditions as the Committee deems appropriate.

         (g) GOVERNING LAW. The Plan and all awards made and actions taken
thereunder shall be governed by and construed in accordance with the laws of the
State of Tennessee, without regard to the principles of conflicts of law
thereof.

         (h) BUYOUT PROVISIONS. The Committee may at any time offer to buy out
for a payment in cash, shares of Common Stock, or Restricted Stock an Option
previously granted, based on such terms and conditions as the Committee shall
establish and communicate to the optionee at the time that such offer is made.

         (i) AWARD PROVISIONS MAY DIFFER. The provisions of awards need not be
the same with respect to each recipient.

         (j) LIABILITY AND INDEMNIFICATION OF BOARD AND COMMITTEE MEMBERS. The
members of the Committee and the Board shall not be liable to any employee or
other person


                                       20

<PAGE>   21

with respect to any determination made hereunder in a manner that is not
inconsistent with their legal obligations as members of the Board. In addition
to such other rights of indemnification a they may have as directors or as
members of the Committee, the members of the Committee shall be indemnified by
the Corporation against the reasonable expenses, including attorneys' fees
actually and necessarily incurred in connection with the defense of any action,
suit or proceeding, or in connection with any appeal therein, to which they or
any of them may be a party by reason of any action taken or failure to act under
or in connection with the Plan or any option granted thereunder, and against all
amounts paid by them in settlement thereof (provided such settlement is approved
by independent legal counsel selected by the Corporation) or paid by them in
satisfaction of a judgment in any such action, suit or proceeding, except in
relation to matters as to which it shall be adjudged in such action, suit or
proceeding that such Committee member is liable for negligence or misconduct in
the performance of his duties; provided that within 60 days after institution of
any such action, suit or proceeding, the Committee member shall in writing offer
the Corporation the opportunity, at its own expense, to handle and defend the
same.

SECTION 13.  EFFECTIVE DATE OF PLAN.

         The Plan was adopted by the Board and approved by the sole shareholder
of the Corporation on February 2, 1995. The Plan was subsequently amended as of
March 6, 1996 by the Company's shareholders and by the Board of Directors on
February 21, 1997. The Plan became effective June 7, 1995.

SECTION 14.  TERM OF PLAN.

         No Stock Option, Stock Appreciation Right, Restricted Stock award or
Other Stock-Based Award shall be granted pursuant to the Plan on or after the
tenth anniversary of the date of adoption of the Plan by the Board, but awards
granted prior to such tenth anniversary may be extended beyond that date.
