TAX ISSUES RELATED TO EXERCISE OF STOCK OPTIONS


This  memorandum  reviews the tax effects  upon the  exercise of  "Non-Incentive
Stock Options"  ("NSOs") (those options  awarded to  non-employee  directors and
perhaps to some officers) and "Incentive Stock Options"  ("ISOs") (those options
generally awarded to officers and employees).

A .      Exercise of an NSO
         ------------------

Upon the  exercise of an NSO,  the amount by which the fair market  value of the
shares on the date of exercise  exceeds the exercise  price will be taxed to the
optionee as ordinary income.  The Company will be entitled to a deduction in the
same amount,  provided it makes all required  withholdings  on the  compensation
element of the  exercise.  In general,  the  optionee's  tax basis in the shares
                           -----------------------------------------------------
acquired by  exercising  an NSO is equal to the fair market value of such shares
- --------------------------------------------------------------------------------
on the date of exercise.  Upon a subsequent sale of any such shares in a taxable
- -----------------------
transaction,  the optionee  will  realize  capital  gain or loss  (long-term  or
short-term,  depending  on whether  the shares were held for more than 12 months
before the sale) in an amount equal to the  difference  between his or her basis
in the shares and the sale price.

Special rules apply if an optionee pays the exercise price upon exercise of NSOs
with previously acquired shares of stock. Except as described below with respect
to shares acquired pursuant to ISOs, such a transaction is treated as a tax-free
exchange of the old shares for the same number of new  shares.  To that  extent,
the  optionee's  basis in the new  shares is the same as his or her basis in the
old shares,  i.e.,  there is a carryover of basis,  and the capital gain holding
period  runs  without  interruption  from the  date  when  the old  shares  were
acquired.  The value of any new shares received by the optionee in excess of the
number of old shares  surrendered  less any cash the  optionee  pays for the new
shares will be taxed as ordinary income.  The optionee's basis in the additional
shares is equal to the fair  market  value of such shares on the date the shares
were  transferred,  and the capital  gain holding  period  commences on the same
date.  The  effect of these  rules is to defer the date when any gain in the old
shares  that are used to buy new shares  must be  recognized  for tax  purposes.
Stated differently,  these rules allow an optionee to finance the exercise of an
NSO by using shares of stock that he or she already owns, without paying current
tax on any unrealized appreciation in the value of all or a portion of those old
shares.

B.       Exercise of an ISO
         ------------------

The holder of an ISO will not be subject to federal income tax upon the exercise
of the ISO, and the Company will not be entitled to a tax deduction by reason of
such  exercise,  provided  that the holder is still  employed by the Company (or
terminated  employment  no longer than three months  before the exercise  date).
Additional  exceptions to this exercise timing  requirement apply upon the death
or disability of the optionee.  A sale of the shares  received upon the exercise
of an ISO which occurs both more than one year after the exercise of the ISO and
more than two years after the grant of the ISO will result in the realization of
long-term  capital  gain or loss in the  amount of the  difference  between  the
amount  realized on the sale and the exercise price for such shares.  Generally,
upon a sale  or  disposition  of  the  shares  prior  to the  foregoing  holding
requirements (referred to as a "disqualifying  disposition"),  the optionee will
recognize  ordinary  income,  and  the  Company  will  receive  a  corresponding
deduction  equal to the lesser of (I) the excess of the fair market value of the
shares on the date of transfer to the optionee over the exercise  price, or (ii)
the excess of the amount realized on the disposition over the exercise price for
such shares.  Currently, ISO exercises are exempt from FICA and FUTA taxes and a
disqualifying disposition is exempt from employer withholding.



A special rule applies if an optionee pays all or part of the exercise  price of
an ISO by  surrendering  shares of stock that he or she  previously  acquired by
exercising  any other ISO. If the  optionee  has not held the old shares for the
full duration of the applicable  holding periods before  surrendering them, then
the  surrender  of such  shares to  exercise  the new ISO will be  treated  as a
disqualifying disposition of the old shares. As described above, the result of a
disqualifying disposition is the loss of favorable tax consequences with respect
to the acquisition of the old shares pursuant to the previously exercised ISO.

Where the  applicable  holding  period  requirements  have been met,  the use of
previously  acquired  shares  of stock to pay all or a portion  of the  exercise
price of an ISO may offer significant tax advantages, particularly a deferral of
the recognition of any appreciation in the surrendered shares in the same manner
as discussed above with respect to NSOs.

C.       Alternative Minimum Tax
         -----------------------

The "alternative minimum tax" is paid when such tax exceeds a taxpayer's regular
federal  income  tax.  The  alternative  minimum  tax  is  calculated  based  on
alternative  minimum taxable income,  which is taxable income for federal income
tax purposes,  modified by certain  adjustments  and increased by tax preference
items.

The spread under an ISO - i.e., the difference between (a) the fair market value
of the  shares  at  exercise  and (b) the  exercise  price  - is  classified  as
alternative minimum taxable income for the year of exercise. Alternative minimum
taxable  income  may be subject  to the  alternative  minimum  tax.  However,  a
disqualifying  disposition of the shares subject to the ISO during the same year
in which the ISO was exercised will  generally  cancel the  alternative  minimum
taxable income generated upon exercise of the ISO.

When a taxpayer sells stock acquired  through the exercise of an ISO,  generally
only the  difference  between the fair market value of the shares on the date of
exercise and the date of sale is used in computing the alternative  minimum tax.
The portion of a taxpayer's  minimum tax  attributable  to certain  items of tax
preference  (including  the spread upon the  exercise of an ISO) can be credited
against  the  taxpayer's  regular  liability  in later  years to the extent that
liability exceeds the alternative minimum tax.
