Incentive Stock Option shall not be granted to a Ten Percent Shareholder except
on such terms concerning the option price and period of exercise as are provided
in Sections 8.01, 8.02 and 8.03.

     4.  Administration of Plan

     4.01  The Plan shall be administered and interpreted by the Committee,

will be granted, in determining the type and amount of Awards to be granted to 
each such Employee, the terms and conditions of Awards and the terms of 
agreements which will be entered into with Holders in connection with Awards.

registered under the 1934 Act, each such member shall be a Disinterested Person.

     4.02  The Committee's powers shall include, but not be limited to, the

advisable. The Committee shall have the power unilaterally and without approval

granted by the Award and so long as the 

                                      -7-


 
amended Award comports with the terms of the Plan. Amendments adverse to the 
interests of the Holder (with respect to an existing Award) must be approved by 
the Holder. Any interpretation by the Committee of the terms and provisions of 
the Plan and the administration thereof, and all determinations made and 
actions taken by the Committee, shall be final and binding on Plan participants 
and shall be uncontestable.

     5.  Shares of Stock Subject to the Plan

shares of Stock available for Awards under the Plan shall be 250,000 shares.

     5.02  Any shares issued by Parent in a business combination transaction 
through the assumption or substitution of outstanding awards made by an 
acquired company shall not reduce the shares available for Awards under the 
Plan. If any shares subject to any Award granted hereunder are forfeited or such
Award otherwise terminates without the issuance of such shares or the payment of
other consideration in lieu of such shares, the shares subject to such Award,
to the extent of any such forfeiture or termination, shall again be available
for Awards under the Plan.

                                      -8-

           An Award of Deferred Stock shall be subject to the following terms
and conditions:

           6.01  Upon determination of the number of shares of Deferred Stock to
     be awarded to a Holder, the Committee shall direct that the same be
     credited to the Holder's account on the books of Parent but that issuance
     and delivery of the same shall be deferred until the date or dates provided
     in Section 6.03 hereof. Prior to such issuance and delivery, the Holder
     shall have no rights as a shareholder with respect to any shares of 
     Deferred Stock credited to the Holder's account.

           6.02  Amounts equal to any dividends declared and paid during the
     Deferral Period with respect to the number of shares covered by a Deferred
     Stock Award will be paid to the Holder currently, or deferred and deemed to
     be reinvested in additional Deferred Stock, or otherwise reinvested on
     such terms as determined at the time of the Award by the Committee in its
     sole discretion.

           6.03  The Deferred Stock agreement shall specify the duration of the
     Deferral Period taking into account termination of employment on account
     of death, disability, Retirement or other cause. The Deferral Period may
     consist of one or more installments. At the end of the Deferral

                                      -9-

 

     Period or any installment thereof, certificates representing the shares
     of Deferred Stock applicable to such Period or installment credited to
     the account of a Holder shall be issued and delivered to the Holder (or,
     where appropriate, the Holder's legal representative) in accordance with
     the terms of the Deferred Stock agreement. The Committee may, in its sole
     discretion, accelerate the delivery of all or any part of a Deferred Stock
     Award or waive the deferral limitations for all or any part of a Deferred
     Stock Award.

     7.  Restricted Stock

           An Award of Restricted Stock shall be subject to the following terms
and conditions:

           7.01  Upon determination of the number of shares of Restricted Stock
     to be granted to a Holder, the Committee shall direct that a certificate or
     certificates representing such number of shares be issued to the Holder and
     registered in the Holder's name. The certificate(s) representing such
     shares shall be legended as to sale, transfer, assignment, pledge or other
     encumbrance during the Restriction Period and deposited by the Holder,
     together with a stock power with respect to the transfer thereof endorsed
     in blank, with Parent, to be held in escrow during the Restriction Period.

                                     -10-



           7.02  During the Restriction Period the Holder shall have the right
     to receive dividends from and to vote the shares of Restricted Stock.

           7.03  The Restricted Stock agreement shall specify the duration of
     the Restriction Period and the performance, employment or other conditions
     (including termination of employment on account of death, disability,
     Retirement or other cause) under which the Restricted Stock may be 
     forfeited to Parent. At the end of the Restriction Period the restrictions
     imposed hereunder shall lapse with respect to the number of shares of
     Restricted Stock as determined by the Committee, and the legend shall be
     removed and the certificates for such number of shares delivered to the
     Holder (or, where appropriate, the Holder's legal representative). The
     Committee may, in its sole discretion, modify or accelerate the vesting of
     shares of Restricted Stock.

     8.  Options

           An Award of Options shall be subject to the following terms and
conditions:   

           8.01  The price per share at which Stock may be purchased upon 
     exercise of an Option shall be determined by the Committee, but in the case
     of grants of ISOs, shall be not less than the Fair Market Value on the
     Award Date. In 

                                     -11-



     the case of any ISO granted to a Ten Percent Shareholder, the option price
     per share shall not be less than 110% of the Fair Market Value on the
     Award Date.

           8.02  The Option agreement shall specify when an Option may be
     exercisable and the terms and conditions applicable thereto and whether
     the Option is an ISO or an NQO. The term of an Option shall in no event
     be longer than twenty years (five years in the case of an ISO granted to
     a Ten Percent Shareholder).

           8.03  Each provision of the Plan and each Option agreement relating
     to an ISO shall be construed so that each ISO shall be an incentive stock
     option as defined in Section 422 of the Code, and any provisions of the
     Option agreement thereof that cannot be so construed shall be disregarded.
     In no event may an ISO be granted after December 26, 2001. ISOs may only
     be granted to employees of the Company.

           8.04  No Option shall be transferable otherwise than by will or the
     laws of descent and distribution and, during the lifetime of the Holder,
     shall be exercisable only by the Holder. Upon the death of a Holder, the
     person to whom the rights have passed by will or by the laws of descent
     and distribution may exercise an Option only in accordance with this 
     Section 8.

                                    -12-  

 

           8.05  The Option price of the shares of Stock payable upon the
     exercise of an Option shall be paid in full in cash at the time of the
     exercise or, with the consent of the Committee, in whole or in part in
     shares of Stock valued at Fair Market Value on the date of exercise.
     With the consent of the Committee, payment upon the exercise of a NQO
     may be made in whole or in part (as determined by the Committee) by
     Restricted Stock based on Fair Market Value on the date of exercise.
     In such case, the shares of Stock to which the Option relates shall be
     subject to the same forfeiture restrictions originally imposed on the
     shares of Restricted Stock exchanged therefor.

     9.  Stock Appreciation Rights

     An Award of SARs shall be subject to the following terms and conditions:

           9.01  A SAR may be granted in tandem with all or a portion of a 
     related Option ("Tandem SAR"), or may be granted separately ("Freestanding
     SAR"). A Tandem SAR may be granted either at the Award Date of the Option
     or at any time thereafter during the term of the Option and shall be
     exercisable only to the extent that the related Option is exercisable. In
     no event shall any SAR be exercisable within the first six months of its
     grant.

                                     -13-

 
           9.02  The base price of a Tandem SAR shall be the option price under 
     the related Option. The base price per share of a Freestanding SAR shall be
     not less than 100% of Fair Market Value on the Award Date of the
     Freestanding SAR.

           9.03  A SAR shall entitle the Holder to receive a payment equal to 
     the excess of the aggregate Fair Market Value of the shares of Stock
     covered by the SAR on the date of exercise over the base price of the SAR.
     Such payment may be in cash or in shares of Stock, Deferred Stock or
     Restricted Stock, or in any combination thereof, as the Committee shall
     determine. Upon exercise of a Tandem SAR as to some or all of the shares of
     Stock covered, the related option shall be cancelled automatically to the
     extent of the number of shares of Stock covered by such exercise, and such
     shares shall no longer be available for purchase under the Option
     pursuant to Section 8. Conversely, if the related Option is exercised as to
     some or all of the shares of Stock covered thereby, the related Tandem
     SAR, if any, shall be cancelled automatically to the extent of the number
     of shares of Stock covered by the Option exercise.

           9.04  SARs shall be subject to the same terms and conditions 
     applicable to Options as stated in Sections 8.02 and 8.04. SARs shall
     also be subject to such other terms
     
                                     -14-


 
and conditions not inconsistent with the Plan as shall be determined by the 
Committee. 

     10.  Adjustments Upon Changes in Capitalization

     In the event of a Restructuring of Parent affecting Stock, or any 
distribution to shareholders other than a cash dividend, the Board shall make 
appropriate adjustment in the number and kind of shares authorized by the Plan 
and such adjustments to outstanding Awards as it determines appropriate 
(including, without limitation, an adjustment to Options to provide that the 
Holders of Options shall receive solely the consideration such Holders would 
have received if the Option had been exercised (whether or not then currently 
exercisable) immediately prior to the Restructuring). No fractional shares of 
Stock shall be issued pursuant to such an adjustment, but an amount equivalent 
to the portion of Fair Market Value attributable to any such fractional shares 
shall, where appropriate, be paid in cash to the Holder.

                                     -15-


 

     11.  Registration of Stock

     If the Stock is registered under the 1934 Act, Parent shall, as soon as 
practicable thereafter, file a registration statement on Form S-8 with the SEC 
under the Securities Act of 1933, as amended, covering the shares of Stock which
may be issued under the Plan.

     12.  Termination and Amendment

     The Plan shall remain in full force and effect until terminated by the 
Board. The Board shall have the power to amend, suspend or terminate the Plan at
any time, provided that no such amendment shall be made without shareholder 
approval which shall:

           (a) Increase (except as provided in Section 10) the total number of 
     shares available for issuance pursuant to the Plan;

           (b) Change the class of employees eligible to be Holders;

           (c) Change the provisions of this Section 11; or

           (d) Effect other changes for which shareholder approval would be 
     required under Rule 16b-3 under the 1934 Act or any successor provision
     promulgated by the SEC.

     Termination of the Plan pursuant to this Section 12 shall not affect Awards
outstanding under the Plan at the time of termination.

                                     -16-


 
     13.  Non-Assignability

     Awards may not be pledged, assigned or transferred for any reason during 
the Holder's lifetime, and any attempt to do so shall be void and relevant Award
shall be forfeited.

     14.  General Provisions 

     14.01  Nothing contained in the Plan, or an Award granted pursuant to the 
Plan, shall confer upon an Employee any right with respect to continuance of 
employment by the Company or an Affiliate, nor interfere in any way with the 
right of the Company or an Affiliate to terminate such employment at any time.

     14.02  For purposes of this Plan, transfer of employment between any of 
Parent, Subsidiaries and Affiliates shall not be deemed termination of 
employment.

     14.03  Holders shall make appropriate provision for all taxes required to
be withheld in connection with any Award, the exercise thereof and the transfer
of shares of Stock pursuant to this Plan. Such responsibility shall extend to
all applicable Federal, state, local or foreign withholding taxes. In the case
of payment of Awards in the form of Stock, or exercise of Options or SARs,
Parent shall, at the election of the Holder and with the consent of the
Committee, have the right to retain the number of shares of Stock whose
aggregate Fair Market Value equals the amount to

                                     -17-


 
be withheld in satisfaction of the applicable withholding taxes. Agreements 
evidencing such Awards shall contain appropriate provisions to effect 
withholding in this manner.

     14.04  Without amending the Plan, Awards may be granted to Employees who 
are foreign nationals or employed outside the United States or both, on such 
terms and conditions different from those specified in the Plan as may, in the 
judgment of the Committee, be necessary or desirable to further the purpose
of the Plan. 

     14.05  To the extent that Federal laws (such as the 1934 Act, the Code or 
the Employee Retirement Income Security Act of 1974) do not otherwise control, 
the Plan and all determinations made and actions taken pursuant hereto shall be 
governed by the laws of the Commonwealth of Pennsylvania and construed 
accordingly.

Adopted:  December 27, 1991
