                                   ARTICLE X

                  ADJUSTMENT FOR RECAPITALIZATION, MERGER, ETC.

               (a) The aggregate number of shares of Common Stock which may be
purchased pursuant to Options granted hereunder, the maximum number of shares of
Stock with respect to which Options may be granted to any single Optionee during
any calendar year, the number of shares of Common Stock covered by each
outstanding Option and the price per share thereof shall be appropriately

                                      -4-
<PAGE>

common stock or the same amount of property, cash or other securities as he
would have been entitled to receive upon the occurrence of such Corporate Event
as if he had been, immediately prior to such event or on the record date
relating to such event, the holder of the number of shares of Common Stock
covered by his Option, and (ii) if the Company is not the surviving corporation
in such Corporate Event, the Company shall require the successor corporation or
parent thereof to assume such outstanding Options; PROVIDED, HOWEVER, that the
Committee may, in its discretion and in lieu of requiring such assumption,
provide that all outstanding Options shall terminate as of the consummation of
such Corporate Event and accelerate the exercisability of all outstanding
Options to any date prior to the date of such Corporate Event.

               (c) The foregoing adjustments and the manner of application of
the foregoing provisions shall be determined by the Committee in its sole
discretion. Any such adjustment may provide for the elimination of any
fractional share which might otherwise become subject to an Option.

               In the event of a Change of Control, each outstanding Option
under the Plan shall vest and become immediately exercisable in full as of the
date immediately preceding the date of such Change of Control, or such other
date, not later than the date of such Change of Control, as shall be established
by the Committee in its discretion. For purposes of the Plan, a "Change of
Control" shall mean:

               (a) The acquisition by any individual, entity or group (within
the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of

(within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 50% or
more of either (i) the then outstanding shares of Common Stock (the "Outstanding
Company Stock") or (ii) the combined voting power of the then outstanding voting
securities of the Company entitled to vote generally in the election of
directors (the "Outstanding Company Voting Securities"); provided, however, that
for purposes of this subsection (a), the following acquisitions shall not
constitute a Change of Control: (i) any acquisition directly from the Company,
(ii) any acquisition by the Company, (iii) any acquisition by any employee
benefit plan (or related trust) sponsored or maintained by the Company, (iv) any
acquisition by WP Ventures, or (v) any acquisition by any corporation pursuant
to a transaction which complies with clauses (i), (ii), and (iii) of subsection
(c) of this Article XI;

               (b) Individuals who, as of the date hereof, constitute the Board
(the "Incumbent Board") cease for any reason to constitute at least a majority
of the Board; provided, however, that any individual becoming a director
subsequent to the effective date of the Plan whose election, or nomination for
election by the Company's stockholders, was approved by a vote of at least a
majority of the directors then comprising the Incumbent Board shall be


                                      -5-
<PAGE>

considered as though such individual were a member of the Incumbent Board, but
excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of an actual or threatened election contest with
respect to the election or removal of directors or other actual or threatened
solicitation of proxies or consents by or on behalf of a Person other than the
Board; or

               (c) Consummation of a Corporate Event, unless, following such
Corporate Event, (i) all or substantially all of the individuals and entities
who were the beneficial owners, respectively, of the Outstanding Company Stock
and Outstanding Company Voting Securities immediately prior to such Corporate
Event beneficially own, directly or indirectly, more than 50% of, respectively,
the then outstanding shares of common stock and the combined voting power of the
then outstanding voting securities entitled to vote generally in the election of
directors of the corporation resulting from such Corporate Event (including,
without limitation, a corporation which as a result of such transaction owns the
Company or all or substantially all of the Company's assets either directly or
through one or more subsidiaries) upon consummation of such Corporate Event in
substantially the same proportions as their ownership, immediately prior to such
Corporate Event, of the Outstanding Company Stock and Outstanding Company Voting
Securities, as the case may be, (ii) no Person other than (1) WP Ventures, (2)
any corporation resulting from such Corporate Event, or (3) any employee benefit
plan (or related trust) of the Company or such corporation resulting from such
Corporate Event, beneficially owns, directly or indirectly, 50% or more of,
respectively, the then outstanding shares of common stock of the corporation
resulting from such Corporate Event or the combined voting power of the then
outstanding voting securities of such corporation except to the extent that such
ownership existed prior to the Corporate Event, and (iii) at least a majority of
the members of the board of directors of the corporation resulting from such
Corporate Event were members of the Incumbent Board at the time of the execution
of the initial agreement, or of the action of the Board, providing for such
Corporate Event; or

               (d) Approval by the stockholders of the Company of a complete
liquidation or dissolution of the Company.

                                   ARTICLE XII

                             RIGHTS AS A STOCKHOLDER

               An Optionee or a transferee of an Option shall have no rights as
a stockholder with respect to any shares covered by his Option until he shall
have become the holder of record of such shares, and he shall not be entitled to
any dividends or distributions or other rights in respect of such shares for
which the record date is prior to the date on which he shall have become the
holder of record thereof.

                                EMPLOYMENT RIGHTS

                  Nothing in the Plan or in any Option Agreement entered into
hereunder shall confer on any Optionee who is an employee of the Company or any
of its subsidiaries any right to continue in the employ of the Company or any of
its subsidiaries or to interfere in any way with the right of the Company or any
of its subsidiaries to terminate the Optionee's employment at any time.

                                   ARTICLE XIV

                              TRANSFER RESTRICTIONS

               Appropriate legends shall be placed on the stock certificates
evidencing shares issued upon exercise of Options to reflect any relevant
transfer restrictions.

                                   ARTICLE XV

                       AMENDMENT OR DISCONTINUANCE OF PLAN

                  The Board may from time to time, to the extent permitted by
applicable law, amend, suspend, or discontinue the Plan; provided, however, that
the Board may not take any action which would have a material adverse effect on
outstanding Options or any unexercised rights under outstanding Options without
the consent of the Optionee whose options would be adversely affected thereby.

                                   ARTICLE XVI

                             CANCELLATION OF OPTIONS

               The Committee, in its discretion, may, with the express written
consent of the Optionee to be affected, cancel any Option held by such
consenting Optionee hereunder.

                                   ARTICLE XVII

                                  MISCELLANEOUS

               (a) Notwithstanding any other provision of the Plan, the Company
or a subsidiary, as appropriate, shall have the right to deduct from all Option
exercises Common Stock, valued at fair market value on the date of payment, in
an amount necessary to satisfy all Federal, state or local taxes as required by
law to be withheld with respect to such Options. In the alternative, in the sole
discretion of the Company, the Optionee or other person receiving such Common
Stock may be required to pay to the Company or a subsidiary, as appropriate,


                                      -7-
<PAGE>

prior to delivery of such Common Stock, the amount of any such taxes which the
Company or subsidiary is required to withhold, if any, with respect to such
Common Stock. Subject in particular cases to the disapproval of the Committee,
the Company may accept shares of Stock of equivalent fair market value in
payment of such withholding tax obligations if the Optionee elects to make
payment in such manner.

               (b) The obligation of the Company to make payment of Option
exercises in shares of Common Stock or otherwise shall be subject to all
applicable laws, rules, and regulations, and to such approvals by governmental
agencies as may be required. Notwithstanding any terms or conditions of any
Option to the contrary, the Company shall be under no obligation to offer to
sell or to sell and shall be prohibited from offering to sell or selling any
shares of Common Stock pursuant to an Option unless such shares have been
properly registered for sale pursuant to the Securities Act of 1933 with the
Securities and Exchange Commission or unless the Company has received advice of
counsel, satisfactory to the Company, that such shares may be offered or sold
without such registration pursuant to an available exemption therefrom and the
terms and conditions of such exemption have been fully complied with. The
Company shall be under no obligation to register for sale under the Securities
Act of 1933 any of the shares of Common Stock to be offered or sold under the
Plan. If the shares of Stock offered for sale or sold under the Plan are offered
or sold pursuant to an exemption from registration under the Securities Act of
1933, the Company may restrict the transfer of such shares and may legend the
Stock certificates representing such shares in such manner as it deems advisable
to ensure the availability of any such exemption.

               (c) The Plan shall be governed by and construed in accordance
with the laws of the State of Delaware without reference to the principles of
conflicts of law thereof.

               (d) No provision of the Plan shall require the Company, for the
purpose of satisfying any obligations under the Plan, to purchase assets or
place any assets in a trust or other entity to which contributions are made or
otherwise to segregate any assets, nor shall the Company maintain separate bank
accounts, books, records or other evidence of the existence of a segregated or
separately maintained or administered fund for such purposes.

               (e) Except as otherwise specifically provided in the relevant
plan document, no payment under the Plan or other amount required to be reported
as income for Federal income tax purposes shall be taken into account in
determining any benefits under any pension, retirement, profit sharing, group
insurance or other benefit plan of the Company.

               (f) The expenses of administering the Plan shall be borne by the
Company. The proceeds received by the Company from the exercise of any Options
pursuant to the Plan will be used for general corporate purposes.

               (g) Masculine pronouns and other words of masculine gender shall
refer to both men and women.

               (h) The titles and headings of the sections in the Plan are for
convenience of reference only, and in the event of any conflict, the text of the
Plan, rather than such titles or headings, shall control.

               (i) Except as otherwise specifically provided in the Plan, no
person shall be entitled to the privileges of ownership in respect of shares of
Common Stock which are subject to Options hereunder until such shares have been
issued to that person.

                                  ARTICLE XVIII

                           SPECIAL PROVISIONS FOR ISOS

               (a) ISOs must be granted within ten years from the date the Plan
is adopted, or the date the Plan is approved by the stockholders of the Company,
whichever is earlier.

               (b) ISOs may not be exercised after the expiration of ten years
from the date such ISOs are granted.

               (c) The Exercise Price of ISOs may not be less than the fair
market value of a share of Common Stock at the time such ISOs are granted, as
determined by the Committee. In such case, fair market value shall be determined
in a manner consistent with the rules and regulations under Section 422 of the
Code.

               (d) ISOs may not be granted to a person who owns stock possessing
more than 10% of the total combined voting power of all classes of stock of the
Company or any "subsidiary corporation" of the Company within the meaning of
Section 424(f) of the Code.

               (e) To the extent the aggregate fair market value of the Common
Stock with respect to which ISOs are exercisable for the first time by any
Optionee during a calendar year (under all plans of the Company and all
"subsidiary corporations" of the Company within the meaning of Section 424(f) of
the Code) exceeds $100,000, such ISOs shall be treated as Non-Qualified Options.
For purposes of the preceding sentence, the fair market value of the Common
Stock shall be determined by the Committee at the time the ISO covering such
stock is granted.

               (f) No ISOs may be granted under the Plan unless the Plan has
been approved by the stockholders of the Company within 12 months before or
after the date of the Plan's adoption by the Board.
