applicable rules established by the Committee. Such notice shall be
substantially in the form attached as Exhibit B (or such other form as is
prescribed by the Committee); and one or more of the following:

                  (i) In cash, by certified or bank check or other instrument
         acceptable to the Committee;

                  (ii) In the form of shares of Stock that are not then subject
         to restrictions under any plan and that have been held by the optionee
         for at least six (6) months (or such other period as established from
         time to time by the Committee in order to avoid adverse accounting
         treatment applying generally accepted accounting principles), if
         permitted by the Committee in its discretion. Such surrendered shares
         shall be valued at Fair Market Value on the exercise date; or


                                      -3-




<PAGE>


                  (iii) In the sole discretion of the Committee, at any time
         during which the Stock is traded on a national stock exchange or
         quotation system, by the optionee delivering to the Company a properly
         executed exercise notice together with irrevocable instructions to a
         broker to promptly deliver to the Company cash or a check payable and
         acceptable to the Company to pay the purchase price; provided that in
         the event the optionee chooses to pay the purchase price as so
         provided, the optionee and the broker shall comply with such procedures
         and enter into such agreements of indemnity and other agreements as the
         Committee shall prescribe as a condition of such payment procedure.

                  (b) (i) Full payment (in cash or by check) for the shares with
         respect to which the Option or portion thereof is exercised, to the
         extent permitted under applicable laws; or

                      (ii) With the consent of the Committee, such payment may
         be made, in whole or in part, through the delivery of shares of Stock
         which have been owned by the Optionee for at least six months, duly
         endorsed for transfer to the Company with a Fair Market Value on the
         date of delivery equal to the aggregate exercise price of the Option or
         exercised portion thereof; or

                      (iii) To the extent permitted under applicable laws,
         through the delivery of a notice that the Optionee has placed a market
         sell order with a broker with respect to shares of Stock then issuable
         upon exercise of the Option, and that the broker has been directed to
         pay a sufficient portion of the net proceeds of the sale to the Company
         in satisfaction of the Option exercise price, provided, that payment of
         such proceeds is made to the Company upon settlement of such sale; or

                      (iv) With the consent of the Committee, any combination of
         the consideration provided in the foregoing subparagraphs (i), (ii) and
         (iii); and

         (c) A bona fide written representation and agreement, in such form as
is prescribed by the Committee, signed by the Optionee or other person then
entitled to exercise such Option or portion thereof, stating that the shares of
Stock are being acquired for the Optionee's own account, for investment and
without any present intention of distributing or reselling said shares or any of
them except as may be permitted under the Securities Act and then applicable
rules and regulations thereunder, and that the Optionee or other person then
entitled to exercise such Option or portion thereof will indemnify the Company
against and hold it free and harmless from any loss, damage, expense or
liability resulting to the Company if any sale or distribution of the shares by
such person is contrary to the representation and agreement referred to above.
The Committee may, in its absolute discretion, take whatever additional actions
it deems appropriate to ensure the observance and performance of such
representation and agreement and to effect compliance with the Securities Act
and any other federal or state securities laws or regulations. Without limiting
the generality of the foregoing, the Committee may require an opinion of counsel
acceptable to it to the effect that any subsequent transfer of shares acquired
on an Option exercise does not violate the Securities Act, and may issue


                                      -4-




<PAGE>


stop-transfer orders covering such shares. Share certificates evidencing Stock
issued on exercise of the Option shall bear an appropriate legend referring to
the provisions of this subsection (c) and the agreements herein. The written
representation and agreement referred to in the first sentence of this
subsection (c) shall, however, not be required if the shares to be issued
pursuant to such exercise have been registered under the Securities Act, and
such registration is then effective in respect of such shares; and

         (d) Full payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option. With the consent of the Committee, (i) shares of
Stock owned by the Optionee for at least six months duly endorsed for transfer
or (ii) shares of Stock issuable to the Optionee upon exercise of the Option,
having a Fair Market Value at the date of Option exercise equal to the statutory
minimum sums required to be withheld, may be used to make all or part of such
payment; and

         (e) In the event the Option or portion thereof shall be exercised
pursuant to Section 4.1 by any person or persons other than the Optionee,
appropriate proof of the right of such person or persons to exercise the Option.

         4.4 Conditions to Issuance of Stock Certificates. The shares of Stock
deliverable upon the exercise of the Option, or any portion thereof, may be
either previously authorized but unissued shares or issued shares which have
then been reacquired by the Company. Such shares shall be fully paid and
nonassessable. The Company shall not be required to issue or deliver any
certificate or certificates for shares of Stock purchased upon the exercise of
the Option or portion thereof prior to fulfillment of all of the following
conditions:

         (a) The admission of such shares to listing on any stock exchange or
national quotation system on which such Stock is then listed; and

         (b) The completion of any registration or other qualification of such
shares under any state or federal law or under rulings or regulations of the
Securities and Exchange Commission or of any other governmental regulatory body,
which the Committee shall, in its absolute discretion, deem necessary or
advisable; and

         (c) The obtaining of any approval or other clearance from any state or
federal governmental agency which the Committee shall, in its absolute
discretion, determine to be necessary or advisable; and

         (d) The receipt by the Company of full payment for such shares,
including payment of all amounts which, under federal, state or local tax law,
the Company (or other employer corporation) is required to withhold upon
exercise of the Option; and

         (e) The lapse of such reasonable period of time following the exercise
of the Option as the Committee may from time to time establish for reasons of
administrative convenience.

         4.5 Rights as Stockholder. The holder of the Option shall not be, nor
have any of the rights or privileges of, a stockholder of the Company in respect
of any shares purchasable


                                      -5-

upon the exercise of any part of the Option unless and until certificates
representing such shares shall have been issued by the Company to such holder.

Plan and this Agreement and to adopt such rules for the administration,
interpretation and application of the Plan as are consistent therewith and to

persons. No member of the Committee shall be personally liable for any action,
determination or interpretation made in good faith with respect to the Plan,
this Agreement or the Option. In its absolute discretion, the Board may at any
time and from time to time exercise any and all rights and duties of the

         (a) Subject to Section 5.2(b), the Option may not be sold, pledged,
assigned or transferred in any manner other than by will or the laws of descent
and distribution unless and until the Option has been exercised, or the shares
underlying such Option have been issued, and all restrictions applicable to such
shares have lapsed. Neither the Option nor any interest or right therein shall
be liable for the debts, contracts or engagements of the Optionee or his or her
successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect, except to the extent that such disposition is
permitted by the preceding sentence.

         (b) Notwithstanding any other provision in this Agreement, with the
consent of the Committee the Option may be transferred to, and exercised by and
paid to certain persons or entities related to the Optionee, including but not
limited to members of the Optionee's family, charitable institutes or trusts or
other entities whose beneficiaries or beneficiary owners are members of the
Optionee's family or to such other persons or entities as may be expressly
approved by the Committee (each a "Permitted Transferee"), pursuant to such
conditions and procedures as the Committee may require.

         (c) Unless transferred to a Permitted Transferee in accordance with
Section 5.2(b), during the lifetime of the Optionee, only the Optionee may
exercise the Option (or any portion thereof). Subject to such conditions and
procedures as the Committee may require, a Permitted Transferee may exercise the
Option or any portion thereof during the Optionee's lifetime. After the death of
the Optionee, any exercisable portion of the Option may, prior to the time when
the Option portion becomes unexercisable under Section 3.3, be exercised by the
Optionee's beneficiary designated in accordance with Section 5(b)(v) of the
Plan. If no beneficiary has been designated or survives the Optionee, the Option
may be exercised by the


                                      -6-




<PAGE>

and agreed to in writing by the Company (which period shall not be longer than
180 days) (the "Market Standoff Period") following the effective date of a

however, that such restriction shall apply only to the first registration

includes securities to be sold on behalf of the Company to the public in an
underwritten public offering under the Securities Act.

         5.4 Restrictive Legends and Stop-Transfer Orders.

transfer" instructions to its transfer agent, if any, and that, if the Company
transfers its own securities, it may make appropriate notations to the same
effect in its own records.

         (c) The Company shall not be required: (i) to transfer on its books any
shares of Stock that have been sold or otherwise transferred in violation of any
of the provisions of this Agreement, or (ii) to treat as owner of such shares of
Stock or to accord the right to vote or pay dividends to any purchaser or other

contrary, the Plan shall be administered, and the Option is granted and may be

regulations. To the extent permitted by applicable law, the Plan and this
Agreement shall be deemed amended to the extent necessary to conform to such

registration requirements is otherwise available.

         5.9 Amendments. This Agreement may not be modified, amended or
