                               SEVERANCE BENEFITS

         2.1 SEVERANCE PAYMENT. Subject to the remaining Sections of this
Article II, if a Covered Employee's employment by the Company shall be subject
to an Involuntary Termination at any time during the period beginning on January
1, 2000 and ending on December 31, 2000, then such Covered Employee shall be
entitled to a severance payment in an amount equal to the sum of (a) 3/52 of
such Covered Employee's Base Salary multiplied by his Years of Service, plus (b)
1/4 of such Covered Employee's Base Salary (which Base Salary, for purposes of
clauses (a) and (b) of


                                      -3-
<PAGE>   4

this sentence, shall be determined as of the date of such Involuntary
Termination). Any severance payment payable pursuant to this Section 2.1 shall
be paid to the Covered Employee in a lump sum cash payment (less any required
tax withholding) within five days after his Involuntary Termination, subject to
the remaining Sections of this Article II.

         2.2 RELEASE AND FULL SETTLEMENT. Anything to the contrary herein
notwithstanding, as a condition to the receipt of any payment under Section 2.1,
a Covered Employee whose employment by the Company has been subject to an
Involuntary Termination shall first execute a release, in the form established
by the Committee, releasing the Committee, the Board, the Company, and the
Company's shareholders, partners, officers, directors, employees, affiliates,
and agents from any and all claims and from any and all causes of action of any
kind or character, including but not limited to all claims or causes of action
arising out of such Covered Employee's employment with the Company, the
termination of such employment, and the performance of the Company's obligations
hereunder, and the receipt of any benefits provided under Section 2.1 by such
Covered Employee shall constitute full settlement of all such claims and causes
of action.

         2.3 MITIGATION. A Covered Employee shall not be required to mitigate
the amount of any payment provided for in this Article II by seeking other
employment or otherwise, nor shall the amount of any payment provided for in
this Article II be reduced by any compensation or benefit earned by the Covered
Employee as the result of employment by another Company or by retirement
benefits. Except as provided in Section 2.5, the benefits under the Plan are in
addition to any other benefits to which a Covered Employee is otherwise
entitled.

         2.4 EFFECT ON OTHER COMPANY BENEFITS. Except as provided in Section
2.5, any payment provided for in this Article II shall not be reduced by, but
shall be in addition to, any other benefits provided by the Company to which a
Covered Employee is otherwise entitled.

         2.5 OFFSET FOR OTHER SEVERANCE BENEFITS. A severance payment calculated
pursuant to Section 2.1 for a Covered Employee shall be reduced by any other
severance benefits, pay in lieu of notice, or other similar benefits payable to
such Covered Employee from or on behalf of the Company, which becomes payable on
account of such Covered Employee's Involuntary Termination pursuant to any
applicable law, statute, regulation, court order, contractual undertaking of the
Company or other legal requirement, including without limitation, the WARN Act;
provided, however, that if a severance payment calculated pursuant to Section
2.1 is reduced pursuant to the terms of this Section 2.5 as a result of payments
to a Covered Employee pursuant to the WARN Act, then the minimum severance
payment payable under the Plan to such Covered Employee shall not be less than
1/13 of such Covered Employee's Base Salary (determined as of the date of such
Covered Employee's Involuntary Termination).


                                      -4-
<PAGE>   5

         2.6 SEVERANCE PAY PLAN LIMITATION. The Plan is intended to be an
employee welfare benefit plan within the meaning of section 3(1) of ERISA and
the Labor Department regulations promulgated thereunder. Therefore, anything to
the contrary herein notwithstanding, in no event shall any Covered Employee
receive total severance payments under the Plan that exceed the equivalent of
twice such Covered Employee's "annual compensation" (as such term is defined in
29 CFR ss.2510.3-2(b)(2)) during the year immediately preceding his Involuntary
Termination. If total severance payments under the Plan to a Covered Employee
would otherwise exceed the limitation in the preceding sentence, then the amount
payable to such Covered Employee pursuant to Section 2.1 shall be reduced in
order to satisfy such limitation.

         2.7 PARACHUTE PAYMENTS. Anything to the contrary herein
notwithstanding, if the Covered Employee is a "disqualified individual" (as
defined in Section 280G(c) of the Code), and the benefits provided for in
Section 2.1, together with any other payments or benefits which the Covered
Employee has the right to receive from the Company and its affiliates, would
constitute a "parachute payment" (as defined in Section 280G(b)(2) of the Code),
the severance benefits provided hereunder shall be either (a) reduced (but not
below zero) so that the present value of such total amounts received by the
Covered Employee will be one dollar ($1.00) less than three times the Covered
Employee's "base amount" (as defined in Section 280G of the Code) and so that no
portion of such amounts received by the Covered Employee shall be subject to the
excise tax imposed by Section 4999 of the Code or (b) paid in full, whichever
produces the better net after-tax position to the Covered Employee (taking into
account any applicable excise tax under Section 4999 of the Code and any
applicable income tax). The determination as to whether any such reduction in
the amount of the severance benefit is necessary shall be made by the Company in
good faith, and such determination shall be conclusive and binding on the
Covered Employee. If a reduced payment is made and through error or otherwise
that payment, when aggregated with other payments or benefits from the Company
(or its affiliates) used in determining if a "parachute payment" exists, exceeds
one dollar ($1.00) less than three times the Covered Employee's base amount, the
Covered Employee shall immediately repay such excess to the Company upon
notification that an overpayment has been made.


                                      III.

                             ADMINISTRATION OF PLAN

         3.1 APPOINTMENT OF COMMITTEE. The Plan shall be administered by the

         eligibility of any person to participate in the Plan;

                  (d) to make a determination as to the right of any person to a

         employment and the cause of such termination);

                  (e) to appoint such agents, counsel, accountants, consultants,

         administering the Plan;

         3.4 MEMBER'S OWN PARTICIPATION. No Covered Employee or agent of the
Committee may act, vote, or otherwise influence a decision of the Committee
specifically relating to himself as a participant in the Plan.

         3.5 INDEMNIFICATION. The Company shall indemnify and hold harmless each
member of the Committee against any and all expenses and liabilities arising out
of his administrative functions or fiduciary responsibilities, including any
expenses and liabilities that are caused by or result from an act or omission
constituting the negligence of such member in the performance of such functions
or responsibilities, but excluding expenses and liabilities that are caused by
or result from such member's own gross negligence or willful misconduct.
Expenses against which such member shall be indemnified hereunder shall include,
without limitation, the amounts of any settlement or judgment, costs, counsel
fees, and related charges reasonably incurred in connection with a claim
asserted or a proceeding brought or settlement thereof.

         3.6 COMPENSATION, BOND AND EXPENSES. The members of the Committee shall
not receive compensation with respect to their services for the Committee. To
the extent required by applicable law, but not otherwise, Committee members
shall furnish bond or security for the performance of their duties hereunder.
Any expenses properly incurred by the Committee incident to the administration,
termination or protection of the Plan, including the cost of furnishing bond,
shall be paid by the Company.

         3.7 CLAIMS PROCEDURE. Any employee that the Committee determines is
entitled to a benefit under the Plan is not required to file a claim for
benefits. Any employee who is not paid a benefit and who believes that he is
entitled to a benefit or who has been paid a benefit and who believes that he is
entitled to a greater benefit may file a claim for benefits under the Plan in
writing with the Committee. In any case in which a claim for Plan benefits by a
Covered Employee is denied or modified, the Committee shall furnish written
notice to the claimant within 90 days (or within 180 days if additional
information requested by the Committee necessitates an extension of the 90-day
period), which notice shall:

                  (a) state the specific reason or reasons for the denial or
         modification;

                  (b) provide specific reference to pertinent Plan provisions on
         which the denial or modification is based;

                  (c) provide a description of any additional material or
         information necessary for the Covered Employee or his representative to
         perfect the claim, and an explanation of why such material or
         information is necessary; and

                  (d) explain the Plan's claim review procedure as contained
         herein.

In the event a claim for Plan benefits is denied or modified, if the Covered
Employee or his representative desires to have such denial or modification
reviewed, he must, within 60 days


                                      -7-
<PAGE>   8

following receipt of the notice of such denial or modification, submit a written
request for review by the Committee of its initial decision. In connection with
such request, the Covered Employee or his representative may review any
pertinent documents upon which such denial or modification was based and may
submit issues and comments in writing. Within 60 days following such request for
review the Committee shall, after providing a full and fair review, render its
final decision in writing to the Covered Employee and his representative, if
any, stating specific reasons for such decision and making specific references
to pertinent Plan provisions upon which the decision is based. If special
circumstances require an extension of such 60-day period, the Committee's
decision shall be rendered as soon as possible, but not later than 120 days
after receipt of the request for review. If an extension of time for review is
required, written notice of the extension shall be furnished to the Covered
Employee and his representative, if any, prior to the commencement of the
extension period.
