                               Base Salary shall be reviewed no more than
                               twelve (12) months after the last salary
                               increase awarded to the Executive prior to the
                               Change in Control Date and thereafter at least
                               annually. Any increase in Annual Base Salary
                               shall not serve to limit or reduce any other
                               obligation to the Executive under this
                               Agreement. Annual Base Salary shall not be
                               reduced after any such increase and the term
                               Annual Base Salary as utilized in this Agreement
                               shall refer to Annual Base Salary as so
                               increased.

                        (ii)   Annual Bonus.  In addition to Annual Base
                               Salary, the Executive shall be awarded, for each
                               fiscal year ending during the Employment Period,
                               an annual bonus (the "Recent Average Bonus") in
                               cash at least equal to average annual bonus paid
                               to the Executive with respect to the three most
                               recent fiscal years of the Company completed
                               prior to the Change in Control Date.  Each such
                               Recent Average Bonus shall be paid  no later
                               than the end of the third month of the fiscal
                               year next following the fiscal year for which
                               the Recent Average Bonus is awarded, except to
                               the extent that the Executive shall elect to
                               defer the receipt of such Recent Average Bonus.

                        (iii)  Incentive, Savings and Retirement Plans.  During
                               the Employment Period, the Executive shall be
                               entitled to participate in the Company's Long
                               Term Incentive Plan and all savings, retirement
                               and incentive plans, practices, policies and
                               programs applicable generally to other peer
                               executives of the Company and on the same basis
                               as such peer executives, but in no event shall
                               such plans, practices, policies and programs
                               provide the Executive with benefit opportunities
                               less favorable than the most favorable of those
                               provided by the Company for the Executive under
                               such plans, practices, policies and programs as
                               in effect during the one hundred eighty (180)-
                               day period prior to the Change in Control Date.

                        (iv)   Welfare Benefit Plans.  During the Employment
                               Period, the Executive and/or the

                               Executive's family, as the case may be, shall be
                               eligible for participation in and shall receive
                               all benefits under welfare benefit plans,

                               group life, accidental death and travel accident

                               applicable generally to other peer executives of
                               the Company, but in no event shall such plans,
                               practices, policies and programs provide the
                               Executive with benefit opportunities less
                               favorable than the most favorable of those
                               provided by the Company for the Executive under
                               such plans, practices, policies and programs as
                               in effect during the one hundred eighty

                               policies, practices and procedures of the
                               Company to the extent applicable generally to
                               other peer executives of the Company.

                        (vi)   Fringe Benefits.  During the Employment Period,
                               the Executive shall be entitled to fringe

                               practices, programs and policies of the Company
                               in effect for other peer executives of the
                               Company, but in no event shall such plans,

                               Executive with benefit opportunities less
                               favorable than the most favorable of those
                               provided by the Company for the Executive under
                               such plans, practices, policies and programs as
                               in effect during the one hundred eighty (180)-
                               day period prior to the Change in Control Date.

                     Article 3.  Termination of Employment

                  3.1.  Without Cause; For Good Reason.  In the event that

employment with the Company for Good Reason, the Executive shall be entitled to
receive from the Company severance benefits ("Severance Benefits") as follows
(but subject to Sections 3.7 and 3.8):

                  (a)       The Executive shall receive a single lump sum
                            payment within thirty (30) days of the Effective
                            Date of Termination in an amount equal to 2.99
                            times the sum of (i) the highest rate of the
                            Executive's rate of Annual Base Salary in effect
                            during the twelve (12) month period prior to the
                            Change in Control at any time up to and including
                            the Effective Date of Termination and (ii) the
                            Recent Average Bonus.

                  (b)       The Executive shall receive an amount, paid within
                            thirty (30) days of the Effective Date of
                            Termination, equal to the Executive's unpaid Base
                            Salary, accrued but unused vacation pay, earned but
                            unpaid bonuses with respect to the prior fiscal
                            year of the Company and amounts under the Company's
                            Long Term Incentive Plan and all other cash
                            entitlements ("Accrued Obligations") through the
                            Effective Date of Termination.

                  (c)       The Executive shall receive an amount, paid within
                            thirty (30) days of the Effective Date of
                            Termination, equal to the product of (i) the Recent
                            Average Bonus and (ii) a fraction, the numerator of
                            which is the number of days in the current fiscal
                            year through the Effective Date of Termination, and
                            the denominator of which is 365.

                  (d)       All welfare benefits, including medical, dental,
                            vision, life and disability benefits pursuant to
                            plans under which the Executive and/or the
                            Executive's family is eligible to receive benefits
                            and/or coverage shall be continued for a period of
                            thirty-six (36) months after the Effective Date of
                            Termination.  Such benefits shall be provided to
                            the Executive at no less than the same coverage
                            level as in effect as of the Change in Control
                            Date.  The Company shall pay the full cost of such
                            continued benefits, except that the Executive shall
                            bear any portion of such cost as was required to be
                            borne by key executives of the Company generally at
                            the Change in Control Date.

                  (e)       All other benefits under applicable plans,
                            practices, programs and policies of the Company

                                     - 9 -


   10



                            ("Other Benefits") shall be timely paid or
                            provided.

                  3.2. Death. If the Executive's employment is terminated by
reason of the Executive's death during the Employment Period, this Agreement
shall terminate without further obligations to the Executive's legal
representatives under this Agreement, other than for payment of Accrued
Obligations and the timely payment or provision of any Other Benefits. Accrued
Obligations shall be paid to the Executive's estate or beneficiary, as
applicable, in a lump sum in cash within thirty (30) days of the Effective Date
of Termination. With respect to the provision of Other Benefits, the term Other
Benefits as utilized in this Section 3.2 shall include without limitation, and
the Executive's estate and/or beneficiaries shall be entitled to receive,
benefits at least equal to the most favorable benefits provided by the Company
to the estates and beneficiaries of peer executives of the Company under such
plans, programs, practices and policies relating to death benefits, if any, as
in effect with respect to other peer executives and their beneficiaries at any
time during the one hundred twenty (120)-day period immediately preceding the
Change in Control Date or, if more favorable to the Executive's estate and/or
the Executive's beneficiaries, as in effect on the date of the Executive's
death with respect to other peer executives of the Company and their
beneficiaries.

                  3.3. Disability. If the Executive's employment is terminated
by reason of the Executive's Disability during the Employment Period, this
Agreement shall terminate without further obligations to the Executive, other
than for payment of Accrued Obligations and the timely payment or provision of
Other Benefits. Accrued Obligations shall be paid to the Executive in a lump
sum in cash within thirty (30) days of the Effective Date of Termination. With
respect to the provision of Other Benefits, the term Other Benefits as utilized
in this Section 3.3 shall include, and the Executive shall be entitled after
the Effective Date of Termination to receive, disability and other benefits at
least equal to the most favorable of those generally provided by the Company to
disabled executives and/or their families in accordance with such plans,
programs, practices and policies relating to disability, if any, as in effect
generally with respect to other peer executives and their families at any time
during the one hundred twenty (120)-day period immediately preceding the
Effective Date of Termination or, if more favorable to the Executive and/or the
Executive's family, as in effect at any time thereafter generally with respect
to other peer executives of the Company and their families.

                  3.4.      With Cause; Other than for Good Reason.  If the
Executive's employment shall be terminated for Cause during the Employment
Period or if the Executive voluntarily terminates

                                        - 10 -


   11



employment during the Employment Period, excluding a termination for Good
Reason, this Agreement shall terminate without further obligations to the
Executive, other than for Accrued Obligations and the timely payment or
provision of Other Benefits. In such case, all Accrued Obligations shall be
paid to the Executive in a lump sum in cash within thirty (30) days of the
Effective Date of Termination.

                  3.5. Termination in Anticipation of Change in Control.
Anything in this Agreement to the contrary notwithstanding, if the Executive's
employment with the Company is terminated prior to the date on which a Change
in Control occurs either (i) by the Company other than for Cause or (ii) by the
Executive for Good Reason, and it is reasonably demonstrated that termination
of employment (a) was at the request of an unrelated third party who has taken
steps reasonably calculated to effect a Change in Control, or (b) otherwise
arose in connection with or in anticipation of the Change in Control, then for
all purposes of this Agreement the termination shall be deemed to have occurred
upon a Change in Control and the Executive will be entitled to Severance
Benefits as provided in Section 3.1 hereof.

                  3.6. Notice of Termination. Any termination by the Company
for Cause or by the Executive for Good Reason shall be communicated by Notice
of Termination to the other party. For purposes of this Agreement, a "Notice of
Termination" means a written notice which (i) indicates the specific
termination provision in this Agreement relied upon, (ii) to the extent
applicable, sets forth in reasonable detail the facts and circumstances claimed
to provide a basis for termination of the Executive's employment under the
provision so indicated and (iii) if the Effective Date of Termination is other
than the date of receipt of such notice, specifies the termination date (which
date shall be not more than thirty (30) days after the giving of such notice).
The failure by the Executive or the Company to set forth in the Notice of
Termination any fact or circumstance which contributes to a showing of Good
Reason or Cause shall not waive any right of the Executive or the Company,
respectively, hereunder or preclude the Executive or the Company, respectively,
from asserting such fact or circumstance in enforcing the Executive's or the
Company's rights hereunder.

                  3.7.  Withholding of Taxes.  The Company shall withhold from
any amounts payable under this Agreement all federal, state, local, or other
taxes as legally shall be required to be withheld.

                  3.8.  Certain Excise Taxes.  Notwithstanding any other
provision of this Agreement to the contrary, if tax counsel selected by the
Company and acceptable to the Executive (which acceptance shall not be
unreasonably withheld) determines that any portion of any payment under this
Agreement would constitute

                                     - 11 -


   12



an "excess parachute payment," then the payments to be made to the Executive
under this Agreement shall be reduced (but not below zero) such that the value
of the aggregate payments that the Executive is entitled to receive under this
Agreement and any other agreement or plan or program of the Company shall be
one dollar ($1) less than the maximum amount of payments which the Executive
may receive without becoming subject to the tax imposed by Section 4999 of the
Internal Revenue Code; provided, however, that the foregoing limitation shall
not apply in the event that such tax counsel determines that the benefits to
the Executive under this Agreement on an after-tax basis (i.e., after federal,
state and local income and excise taxes) if such limitation is not applied
would exceed the after-tax benefits to the Executive if such limitation is
applied.  Such tax counsel shall make such determinations, and provide to the
Company and the Executive written notice supporting such determinations, within
fifteen (15) business days after the Change in Control.

                  3.9. Confidential Information. The Executive shall hold in a
fiduciary capacity for the benefit of the Company all secret or confidential
information, knowledge or data relating to the Company or any of its affiliated
companies, and their respective businesses, which shall have been obtained by
the Executive during the Executive's employment by the Company or any of its
affiliated companies and which shall not be or become public knowledge (other
than by acts by the Executive or representatives of the Executive in violation
of this Agreement). After termination of the Executive's employment with the
Company, the Executive shall not, without the prior written consent of the
Company or as may otherwise be required by law or legal process, communicate or
divulge any such information, knowledge or data to anyone other than the
Company and those designated by it. In no event shall an asserted violation of
the provisions of this Section 3.9 constitute a basis for deferring or
withholding any amounts otherwise payable to the Executive under this
Agreement.

                  Article 4. The Company's Payment Obligations

                  4.1. Payment Obligations Absolute. The Company's obligation
to make the payments and the arrangements provided for herein shall be absolute
and unconditional, and shall not be affected by any circumstances, including,
without limitation, any offset, counterclaim, recoupment, defense, or other
right which the Company may have against the Executive or any other party. All
amounts payable by the Company hereunder shall be paid without notice or
demand.  Each and every payment made hereunder by the Company shall be final,
and the Company shall not seek to recover all or any part of such payment from
the Executive or from whomsoever may be entitled thereto, for any reasons
whatsoever. Notwithstanding any other provisions of this Agreement to the
contrary, the Company shall have no obligation to make any payment to the
Executive hereunder to the extent, but

                                        - 12 -


   13



only to the extent, that such payment is prohibited by the terms of any final
order of a Federal or state court or regulatory agency of competent
jurisdiction; provided, however, that such an order shall not affect, impair,
or invalidate any provision of this Agreement not expressly subject to such
order.

                  4.2. Contractual Rights to Benefits. This Agreement
establishes and vests in the Executive a contractual right to the benefits to
which he is entitled hereunder. Nothing herein contained shall require or be
deemed to require, or prohibit or be deemed to prohibit, the Company to
segregate, earmark, or otherwise set aside any funds or other assets, in trust
or otherwise, to provide for any payments to be made or required hereunder. The
Executive shall not be obligated to seek other employment in mitigation of the
amounts payable or arrangements made under any provision of this Agreement, and
the obtaining of any such other employment shall in no event effect any
reduction of the Company's obligations to make the payments and arrangements
required to be made under this Agreement.

                   Article 5.  Enforcement and Legal Remedies

                  5.1 Resolution of Differences Over Breaches of Agreement. In
the event of any controversy, dispute or claim arising out of, or relating to
this Agreement, or the breach thereof, or arising out of any other matter
relating to the Executive's employment with the Company or the termination of
such employment, the Company and the Executive agree that such underlying
controversy, dispute or claim shall be settled by arbitration conducted in
Pittsburgh, Pennsylvania in accordance with this Section 5.1 of the Agreement
and the Commercial Arbitration Rules of the American Arbitration Association.
The matter shall be heard and decided, and award rendered by a panel of three
(3) arbitrators. The Company and the Executive shall each select one arbitrator
from the American Arbitration Association National Panel of Commercial
Arbitrators and the American Arbitration Association shall elect a third
arbitrator from the National Panel of Commercial Arbitrators. The award
rendered by such arbitration panel shall be final and binding as between the
parties hereto and their heirs, executors, administrators, successors and
assigns, and judgment on the award may be entered by any court having
jurisdiction thereof.

                  5.2 Cost of Enforcement. Solely for purposes of determining
the allocation of the costs as described below, the Company will be considered

the Company has not breached this Agreement and (2) the claim by the Executive
or his beneficiary was not made in good faith. Otherwise, Executive or his
beneficiary will be considered the prevailing party. In the event that the
Company is the prevailing party, the fee of the arbitrators and all necessary
expenses of the hearing (excluding

                      Article 6. Binding Effect; Successors

                  The rights of the parties hereunder shall inure to the
benefit of their respective successors, assigns, nominees, or other legal
representatives. The Company shall require any successor (whether direct or
indirect, by purchase, merger, reorganization, consolidation, acquisition of
property or stock, liquidation, or otherwise) to all or a significant portion
of the assets of the Company, as the case may be, by agreement in form and
substance satisfactory to the Executive, expressly to assume and agree to
perform this Agreement in the same manner and to the same extent that the
Company, as the case may be, would be required to perform if no such succession
had taken place. Regardless of whether such agreement is executed, this
Agreement shall be binding upon any successor in accordance with the operation
of law and such successor shall be deemed the "Company," as the case may be,
for purposes of this Agreement.

                         Article 7. Term of Agreement

Agreement and shall continue in effect for three (3) full years. However, in
the event a Change in Control occurs during the term, this Agreement will
remain in effect for the longer of: (i) thirty-six (36) months beyond the month
in which such Change in Control occurred; or (ii) until all obligations of the
Company hereunder have been fulfilled, and until all benefits required
hereunder have been paid to the Executive or other party entitled thereto. The
term of this Agreement shall be extended automatically for one additional year
as of the third anniversary of the date hereof and each subsequent annual
anniversary date hereof, unless, no later than ninety (90) days prior to any
such renewal date, either the Board, on behalf of the Company, or the Executive
gives written notice to the other that the term of this Agreement shall not be
so extended.
