     determined by the Committee, provided that, the exercise price per Share of
     any Incentive Stock Option shall not be less than 100% of the Fair Market

     determine, provided that no Option shall be exercisable after the
     expiration of ten years from the date it is granted (five years in the case
     of an Incentive Stock Option granted to a Ten-Percent Stockholder).

          (c) Vesting. Options shall be exercisable in such installments (which
     need not be equal) and at such times as the Committee may designate, as set
     forth in an Option Agreement. To the extent not exercised, installments
     shall accumulate and may be exercised, in whole or in part, at any time
     after becoming exercisable, but not later than the date the Option
     expires. The Committee may accelerate the exercisability of an Option at
     any time. Notwithstanding the foregoing, any Options that are not
     exercisable prior to a Change in Control shall become exercisable on the
     date of such Change in Control and shall remain exercisable for the
     remainder of their Term.

          (d) Exercise of Option After Termination of Employment.

          Subject to the terms of any written employment agreement and reflected
     in an Option Agreement, an Option granted under the Plan is exercisable by

     are exercisable preceding an Optionee's Termination of Employment for any
     reason other than Cause, shall remain exercisable for the following period:

<PAGE>
                  (i) If the Optionee dies while an Employee, or if his
Termination of Employment is due to Permanent Disability or Retirement, the
Optionee (or his Designated Beneficiary or personal representative, as
applicable) may exercise the Option no later than twelve (12) months after such
death or determination;

                  (ii) If the Optionee's Termination of Employment is for any
reason other than those set forth in (i) above and is not for Cause, the
Optionee may exercise the Option within three months after such termination;

                  (iii) If the Optionee dies during a period described in (i) or
(ii) above, his Designated Beneficiary may exercise such Option no later than
the expiration of such extended period; or

                  (iv) Notwithstanding (i) through (iii) above or anything in an
Option Agreement or the Plan to the contrary, at any time after the grant of an
Option, the Committee, in its sole and absolute discretion and subject to
whatever terms and conditions it selects, may provide that an Option may be
exercised after the relevant extended period set forth above, but in no event
later than the date that it would have expired under the Option Agreement.

         4.2 NONTRANSFERABILITY.

                  No Option granted hereunder shall be transferable by the
Optionee to whom granted otherwise than by will or the laws of descent and
distribution, and an Option may be exercised during the lifetime of such
Optionee only by the Optionee or his guardian or legal representative; provided,
however that an Optionee may designate a beneficiary to exercise his Option or
other rights under the Plan after his death and, in the discretion of the
Committee, Options may be transferable pursuant to a Qualified Domestic
Relations Order ("QDRO"), as determined by the Committee or its designee.

         4.3 METHOD OF EXERCISE.

                  An Option shall be exercised by delivery of a written notice
(in person or by first class mail to the Secretary of the Company at the
Company's principal executive office) which specifies the number of Shares to be
purchased and is accompanied by full payment therefor and otherwise in
accordance with the Option Agreement pursuant to which the Option was granted.
The purchase price for any Shares purchased pursuant to the exercise of an
Option shall be paid in full upon such exercise in cash or by check made payable
to the Company. If requested by the Committee, the Optionee shall deliver the
Option Agreement evidencing the Option to the Secretary of the Company who shall
endorse thereon a notation of such exercise and return such Option Agreement to
the Optionee. Not less than one hundred (100) Shares may be purchased at any
time upon the exercise of an Option unless the number of Shares so purchased
constitutes the total number of Shares then purchasable under the Option or the
Committee determines otherwise, in its sole discretion.

dividend, extraordinary cash dividend, recapitalization, reorganization, merger,
consolidation, split-up, spin-off, combination, exchange of shares, warrants or
rights offering to purchase Shares at a price substantially below fair market
value, or other similar corporate event affects the Shares such that an

intended to be made available under the Plan, the Committee shall, in its sole
discretion, and in such manner as the Committee may deem equitable, adjust any
or all of (a) the number and kind of shares subject to outstanding Options, and
(b) the exercise price with respect to any outstanding Option and/or, if deemed
appropriate, make provision for a cash payment to an Optionee, provided,
however, that the number of Shares subject to any Option shall always be a whole

                  No holder of an Option shall be deemed to be or to have the
rights and privileges of an owner of Shares unless and until certificates
representing such Shares have been issued to such holder. As a condition to any
exercise of the Option by the Optionee, the Optionee shall be required to be a
party to, or to contemporaneously with such exercise become a party to, the

Subsidiary to establish any other forms of incentives or compensation for
Employees.

time the Committee determines, in its sole discretion, that the listing,
registration or qualification of Shares issuable pursuant to the Plan is
required by any securities exchange or under any state or federal law, or the
consent or approval of any governmental regulatory body is necessary or
desirable as a condition of, or in connection with, the grant of an Option or
the issuance of Shares, no Options shall be granted or Shares issued, in whole
or in part, unless listing, registration, qualification, consent or approval has
been effected or obtained free of any conditions as acceptable to the Committee.

                  (d) In the event that the disposition of Shares acquired
pursuant to the Plan is not covered by a then current registration statement

Securities Act or regulations thereunder, and the Committee may require any
individual receiving Shares pursuant to the Plan, as a condition precedent to
receipt of such Shares, to represent to the Company in writing that the Shares
acquired by such individual are acquired for investment only and not with a view
to distribution. The certificate for any Shares acquired pursuant to the Plan

law, no later than the date as to which an amount first becomes includible in
the gross income of an Optionee for federal income tax purposes with respect to
any award granted under the Plan, the Optionee shall pay to the Company, or make

                  (c) Form of Option. Options are to be Incentive Stock Options.

                  (d) Term. The Option shall expire on the      anniversary
(     anniversary in the case of an Incentive Stock Option granted to a
ten-percent stockholder) of the Grant Date, unless terminated earlier by the
Committee.

                  (e) Vesting. Subject to the provisions of Section 4.1(c) of
the Plan, the Options are immediately vested on the Grant Date.

                  (f) Exercise. The Optionee may exercise an Option in whole or
in part at any time by delivering written notice of such exercise to the
Secretary of the Company of the number of Shares as to which the Option is being
exercised, and enclosing payment for the Shares with respect to which the Option
is being exercised. Such payment shall be in cash or by check, made payable to
the Company. Partial exercise shall be for whole Shares only and shall not be
for less than one hundred (100) Shares unless the number of Shares purchased
constitutes the total



                                       11
<PAGE>

number of Shares then remaining subject to the Option or the Committee permits
such smaller exercise in its sole discretion.

                  (g) Exercise Following Termination of Employment. In the event
the Optionee's Termination of Employment is for Cause, the Option, whether
exercisable or nonexercisable, at such time, shall be deemed to have terminated
as of the day preceding such Termination of Employment. If such Termination of
Employment is for any reason other than for Cause, any outstanding portion of
the Option that has become exercisable shall be exercisable for the following
periods:

                           (i)      If the Optionee dies while an Employee, or
                                    if his Termination of Employment is due to
                                    Permanent Disability or Retirement, the
                                    Optionee (or his Designated Beneficiary or
                                    personal representative, as applicable) may
                                    exercise the Option no later than twelve
                                    (12) months after such death or
                                    determination;

                           (ii)     If the Optionee's Termination of Employment
                                    is for any reason other than those set forth
                                    in (i) above and is not for Cause, the
                                    Optionee may exercise the Option within
                                    three months after such termination;

                           (iii)    If the Optionee dies during a period
                                    described in (i) or (ii) above, his
                                    Designated Beneficiary may exercise such
                                    Option no later than the expiration of such
                                    extended period; or

                           (iv)     Notwithstanding (i) through (iii) above or
                                    anything in an Option Agreement or the Plan
                                    to the contrary, at any time after the grant
                                    of an Option, the Committee, in its sole and
                                    absolute discretion and subject to whatever
                                    terms and conditions it selects, may provide
                                    that an Option may be exercised after the
                                    relevant extended period set forth above,
                                    but in no event later than the date that it
                                    would have expired under the Option
                                    Agreement.

                  (h) Nontransferability. The Option shall not be transferable
other than by will or the laws of descent and distribution, and no transfer so
effected shall be effective to bind the Company unless the Company has been
furnished with written notice thereof and a copy of the will and/or such other
evidence as the Committee may deem necessary to establish the validity of the
transfer and the acceptance by the transferee or transferees of the terms and
conditions of the Option, provided, however, that, in the discretion of the
Committee, Options may be transferred pursuant to a Qualified Domestic Relations
Order (within the meaning of the Code).

                  (i) Conditions to Issuance of Stock Certificates.

                           (i)      The Shares deliverable upon the exercise of
                                    the Option, or any portion thereof, may be
                                    either previously authorized but unissued
                                    Shares or issued Shares which have been
                                    reacquired by the Company. Such Shares shall
                                    be fully



                                       12
<PAGE>
                                    paid and non-assessable. The stock
                                    certificates evidencing the Shares shall
                                    bear such legends restricting
                                    transferability as the Committee deems
                                    necessary or advisable.

                           (ii)     The Company shall not be required to issue
                                    or deliver any certificate or certificates
                                    for Shares deliverable upon any exercise of
                                    the Option prior to fulfillment of all of
                                    the following conditions:

                                    1)       The completion of any registration
                                             or other qualification of such
                                             Shares under any federal law or
                                             under rulings or regulations of the
                                             Securities and Exchange Commission
                                             or of any other governmental
                                             regulatory body, or the obtaining
                                             of approval or other clearance from
                                             any state or federal governmental
                                             agency which the Committee shall,
                                             in its sole discretion, deem
                                             necessary or advisable.

                                    2)       If, in its sole discretion, the
                                             Committee deems it necessary or
                                             advisable, the execution by the
                                             Optionee of a written
                                             representation and agreement, in a
                                             form satisfactory to the Committee,
                                             in which the Optionee represents
                                             that the Shares acquired by him
                                             upon exercise are being acquired
                                             for investment and not with a view
                                             to distribution thereof.

                  (j) Rights as Stockholder. The Optionee shall not be, nor have
any of the rights or privileges of, a stockholder of the Company in respect of
any Shares purchasable upon the exercise of the Option unless and until
certificates representing such Shares have been issued by the Company. As a
condition to any exercise of the Option by the Optionee, the Optionee shall be
required to be a party to, or to contemporaneously with such exercise become a
party to, the Stockholders Agreement.

3. MISCELLANEOUS.

                  (a) Administration. The Committee shall have the power to
interpret the Plan and this Agreement, and to adopt such rules for the
administration, interpretation and application of the Plan as are consistent
therewith and to interpret or revoke any such rules. All actions taken and all
interpretations and determinations made by the Committee shall be final and
binding upon the Optionee, the Company, and all other interested persons.

                  (b) Withholding of Taxes. No later than the date as of which
an amount first becomes includible in the gross income of the Optionee for
federal income tax purposes with respect to the grant of the Option under this
Agreement, the Optionee shall pay to the Company, or the Optionee (or his
Designated Beneficiary) shall make arrangements satisfactory to the Company
regarding the minimum statutory payment of, any federal, state, or local taxes
of any kind required by law or the Company to be withheld with respect to such
amount. The obligations of the Company under this Agreement shall be conditioned
on such payment or



                                       13
<PAGE>
arrangements, and the Company shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
Optionee.

                  (c) No Right to Continued Employment. Nothing in this
Agreement or in the Plan shall confer upon the Optionee any right to continue in
the employ of the Company or shall interfere with or restrict in any way the
rights of the Company, which are hereby expressly reserved, to discharge the
Optionee at any time for any reason whatsoever, with or without cause.

                  (d) Entire Agreement; Amendment. This Agreement, and the Plan,
constitute the entire agreement between the parties with respect to the subject
matter hereof, and supersede all prior agreements and understandings between the
parties with respect to such subject matter. Any term or provision of this
Agreement may be waived at any time by the party which is entitled to the
benefit thereof, and any term or provision of this Agreement may be amended or
supplemented at any time by the mutual consent of the parties hereto, except
that any waiver of any term or condition, or any amendment, of this Agreement
must be in writing.

                  (e) Governing Law. The laws of the State of New York shall
govern the interpretation, validity and performance of the terms of this
Agreement regardless of the law that might be applied under principles of
conflict of laws.

                  (f) Successors. This Agreement shall be binding upon and inure
to the benefit of the successors, assigns and heirs of the respective parties.

                  (g) Notices. All notices or other communications made or given
