IV.  BENEFITS UPON TERMINATION

     4.1  Qualifying Termination Not Within the Change in Control Period.  If,
          --------------------------------------------------------------      
during the Term, the Executive's employment with the Company and its
subsidiaries is terminated in a Qualifying Termination and such termination does
not occur during a Change in Control Period:

          (a) the Company shall pay to the Executive in a cash lump sum within

provided if the Executive's employment had not been terminated under the plans,
practices, programs or policies of the Company applicable to the Executive as of
his Date of Termination; and

          (c) all options to acquire stock of the Company and all restricted
stock awards held by the Executive shall become immediately vested and such
options shall become immediately exercisable and shall remain exercisable until
the earlier of (i) the date specified in the applicable option agreement between
the Executive and the Company or (ii) the normal expiration date of any such
option.

     4.2  Qualifying Termination During the Change in Control Period. If, during
          ----------------------------------------------------------            
the Term, the Executive's employment with the Company and its subsidiaries is

Change in Control Period:

          (a) the Company shall pay to the Executive in a cash lump sum within
30 days after the Date of Termination, the sum of (i) all Accrued Obligations
and (ii) the product of three and the sum of the Executive's Base Salary and

          (b) for three years following the Date of Termination, or such longer

                                                                               6

his Date of Termination; and

          (c) all options to acquire stock of the Company and all restricted

options shall become immediately exercisable and shall remain exercisable until
the earlier of (i) the date specified in the applicable option agreement between
the Executive and the Company or (ii) the normal expiration date of any such
option.

          Any provision in this Agreement to the contrary notwithstanding, if a
Change in Control occurs and if the Executive's employment with the Company is
terminated prior to the date on which the Change in Control occurs, and if it is
reasonably demonstrated by the Executive that such termination of employment (x)
was at the request of a third party who had taken steps reasonably calculated to
effect the Change in Control or (y) otherwise arose in connection with or
anticipation of the Change in Control, then for all purposes of this Agreement
the termination of the Executive's employment shall be deemed to have occurred
during a Change in Control Period.

          4.3  Non-Qualifying Termination.  If the Executive's employment with
               --------------------------                                     
the Company and its subsidiaries is terminated in a Non-Qualifying Termination,
this Agreement shall terminate without further obligations to the Executive
other than the Accrued Obligations.

          4.4  Excise Tax Payments.
               ------------------- 

          (a) Notwithstanding anything in the Agreement to the contrary, in the
event of the determination (as hereinafter provided) that any required payment
by the Company to or for benefit of the Executive (whether paid or payable
pursuant to the terms of the Agreement or otherwise (individually and
collectively, "Payment")) would be subject to the excise tax imposed by Section
4999 of the Internal Revenue Code of 1986, as amended (the "Code") or any
successor provision thereto (the "Excise Tax"), the Executive shall be entitled
to receive an additional payment or payments (individually or collectively, "Tax
Assistance

 
                                                                               7

Payment"), which shall include an amount such that, after the Executive pays (1)
all taxes (including any interest or penalties imposed with respect to such
taxes) and (2) any Excise Tax (including interest and penalties with respect
thereto) imposed upon the Tax Assistance Payment, the Executive retains so much
of the Tax Assistance Payment as is equal to the Excise Tax (including interest
and penalties with respect thereto) imposed on the Payment.

          (b) Subject to the provisions hereinafter concerning the provision of
notice of a claim by the Internal Revenue Service, all determinations required
to be made under these provisions, including whether an Excise Tax is payable by
the Executive, the amount of such Excise Tax and whether the Company is required
to pay the Executive a Tax Assistance Payment and the amount of such Tax
Assistance Payment, if any, shall be made by the Company's independent
accountants or such other nationally recognized accounting firm retained by the
Company and reasonably acceptable to the Executive ("Accounting Firm").  The
Company shall direct the Accounting Firm to submit its determination and
detailed supporting calculations to both the Executive and the Company within
thirty (30) days after the payment or provision of any benefit that could give
rise to an Excise Tax and any such other time or times as the Executive or the
Company may request.  If the Accounting Firm determines that any Excise Tax is
payable by the Executive, the Company shall pay the required Tax Assistance
Payment to the Executive within ten (10) business days after the Company
receives such determination and calculations with respect to any Payment to the
Executive.

          (c) Any federal tax returns the Executive files shall be prepared and
filed on a basis consistent with the determination of the Accounting Firm with
respect to the Excise Tax payable by the Executive.  If the Accounting Firm
determines that the Executive is required to pay no Excise Tax, it shall (at the
same time it makes such determination) furnish the Executive and the Company an
opinion that the Executive has substantial authority not to report any Excise
Tax on the Executive's federal income tax return.  However, in view of the
uncertainty concerning application of Section 4999 of the Code (or any successor
provision thereto) at the time of any determination made hereunder by the
Accounting Firm, it is possible that a Tax Assistance Payment that should have
been made by the Company will not have been made ("Underpayment"), consistent
with the calculations required

 
                                                                               8

to be made hereunder.  In the event the Company exhausts or fails to pursue its
remedies pursuant to the provisions concerning notice of a claim by the Internal
Revenue Service, and the Executive thereafter is required to make a payment of
any Excise Tax, the Executive shall direct the Accounting Firm to determine the
amount of the Underpayment and to submit its determination and detailed
supporting calculations as promptly as possible both to the Executive and to the
Company, which shall pay the amount of such Underpayment to the Executive or for
the Executive's benefit within ten (10) business days following the Company's
receipt of such determination and calculations.

          (d) Each of the Executive and the Company shall provide the Accounting
Firm access to and copies of any books, records and documents in the Executive's
or its possession, as the case may be, reasonably requested by the Accounting
Firm, and shall otherwise cooperate with the Accounting Firm in connection with
the preparation and issuance of the determination and calculations required or
contemplated hereunder.

          (e) The Company shall bear the fees and expenses of the Accounting
Firm for services hereunder.  If, for any reason, the Executive initially pays
such fees and expenses, the Company shall reimburse the Executive the full
amount of the same within ten (10) business days following receipt from the
Executive of a statement and reasonable evidence of the Executive's payment
thereof.

          (f) The Executive shall notify the Company in writing of any claim by
the Internal Revenue Service that, if successful, would require the Company to
pay a Tax Assistance Payment.  The Executive shall give such notification as
promptly as practicable, but in no event later than the tenth (10th) business
day next following the Executive's receipt of such claim, and the Executive
further shall apprise the Company of the nature of such claim and the date on
which it is required to be paid (in each case, to the extent known to the
Executive).  The Executive shall not pay or otherwise satisfy such claim prior
to the earlier of (a) the expiration of the thirty (30)-calendar-day period next
following the date on which the Executive gives notice to the Company or (b) the
date any payment of the amount with respect to such claim is due.  If the
Company notifies the Executive in writing prior to the expiration of such

 
                                                                               9

period that it desires to contest such claim, the Executive shall:

          (i)   provide the Company any written records or documents in the
Executive's possession relating to such claim and reasonably requested by the
Company;

          (ii)  take such action in connection with contesting such claim as the
Company reasonably shall request in writing from time to time, including without
limitation accepting legal representation with respect to such claim by an
attorney competent in respect of the subject matter and reasonably selected by
the Company;

          (iii) cooperate with the Company in good faith in order effectively to
contest such claim; and

          (iv)  permit the Company to participate in any proceedings relating to
such claim, provided, however, that the Company directly shall bear and pay all
costs and expenses (including without limitation, interest and penalties)
incurred in connection with such contest and shall indemnify the Executive and
hold the Executive harmless, on an after-tax basis, from and against any and all
Excise Tax or income tax (including without limitation, interest and penalties
with respect thereto), imposed as a result of such claim and payment of costs
and expenses. Without limiting the foregoing, the Company shall control all
proceedings taken in connection with the contest of any claim contemplated by
these provisions and, at its sole option, may pursue or forego any and all
administrative appeals, proceedings, hearings and conferences with the taxing
authority in respect of such claim (provided, however, that the Executive may
participate therein at the Executive's own cost and expense) and may, at its
option, either direct the Executive to pay the tax claimed and sue for a refund
or contest the claim in any permissible manner, and the Executive agrees to
prosecute such contest to a determination before any administrative tribunal, in
a court of initial jurisdiction and in one or more appellate courts, as the
Company shall determine; provided, however, that if the Company directs the
Executive to pay the tax claimed and to sue for a refund, the Company shall
advance the amount of such payment to the Executive, and pay on a current basis
all costs of litigation, including without limitation attorneys' fees, on an
interest-free basis and shall agree to and shall indemnify the Executive and
hold the Executive

 
                                                                              10

harmless, on an after-tax basis, from any Excise Tax or income tax, including
without limitation, interest and penalties with respect thereto, imposed with
respect to such advance; and provided further, however, that any extension of
the statute of limitations relating to payment of taxes for the Executive's
taxable year with respect to which the contested amount is claimed to be due is
limited solely to such contested amount. Furthermore, the Company's control of
any such contested claim shall be limited to issues with respect to which a Tax
Assistance Payment would be payable hereunder, and the Executive shall be
entitled to settle or to contest, as the case may be, any other issue(s) raised
by the Internal Revenue Service or any other taxing authority.

          (g) If, after the Executive receives an amount advanced by the Company
pursuant to provisions of the last full paragraph, the Executive receives any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with any applicable provisions of the same paragraph) promptly pay to
the Company the amount of such refund (together with any interest paid or
credited thereon after any taxes applicable thereto).  If, after the Executive
receives such an amount advanced by the Company, a determination is made that
the Executive shall not be entitled to any refund with respect to such claim and
the Company does not notify the Executive in writing of its intent to contest
such denial of refund prior to expiration of thirty (30) calendar days after
such determination, then such advance shall be forgiven and shall not be
required to be repaid, and the amount of such advance shall offset, to the
extent thereof, the amount of the Tax Assistance Payment the Company is required
to pay the Executive hereunder.

limit the Executive's continuing or future participation in any benefit, bonus,
