The vesting of the SAR shall be subject to the following:

<Page>

Notwithstanding the foregoing schedule, but subject to paragraph (b) below, the
       SAR shall become fully vested upon the date of a Public Offering or
       Change of Control that occurs on or before the Date of Termination. The
       vesting described in this paragraph (a) shall be deemed to occur
       immediately before the exercise of the SAR described in paragraph 3.

If, during any Vesting Period, an Event of Default occurs, then the number of
       Covered Shares that would otherwise vest on the last day of that Vesting
       Period shall instead be forfeited, and in no event shall the Participant
       be entitled to any amounts with respect to such Covered Shares by reason
       of exercise of the SAR, by reason of paragraph (a) above, or for any
       other reason.

If a Public Offering or Change of Control does not occur on or before the
       Participant's Date of Termination, and such Date of Termination occurs
       for reasons other than a Material Breach or Cause, or voluntary
       termination then all rights under the SAR that are not vested on the Date
       of Termination shall expire and all rights under the SAR that have vested
       prior to the Date of Termination shall be subject to repurchase by the
       Company under Section 7(a) of the Management Subscription Agreement,
       dated as of the date hereof, among the Company and certain employees of
       the Company or its subsidiaries. If a Public Offering or Change of
       Control does not occur on or before the Participant's Date of
       Termination, and such Date of Termination occurs by reason of a Material
       Breach, Cause or voluntary termination, then all rights under the SAR
       shall be forfeited on the Date of Termination.

EXERCISE OF SAR. The SAR shall be exercised with respect to the vested portion
       of the Covered Shares on the first to occur of a Public Offering or a
       Change of Control. (For the avoidance of doubt, it is recited here that
       the SAR shall not be exercised except as provided in the preceding
       sentence.) As soon as practicable after the exercise of the SAR with
       respect to a share of Stock, the Participant shall receive a cash payment
       from the Company which is equal to the excess of the Fair Market Value of
       a share of Stock on the date of exercise over the Exercise Price of one
       share of Stock. Notwithstanding the foregoing provisions of this
       paragraph 3, if the SAR would otherwise become exercisable in accordance
       with this paragraph 3 by reason of a Public Offering, and the
       Participant's Date of Termination has not occurred prior to the date of
       the Public Offering, then, in the sole discretion of the Board, the SAR
       may be canceled, provided that, at the time of the Public Offering, the
       Participant will be granted an option to purchase shares of Stock equal
       to the number of Covered Shares. Such option (i) shall be fully
       exercisable at and after the granting of the option (until expiration
       described in clause (iii) below) with respect to all of the Covered
       Shares, (ii) shall have a per-share exercise price equal to the exercise
       price of the SAR; and (iii) shall expire on the earlier of the ten-year
       anniversary of the Grant Date (as defined in this Agreement), but not
       event later than the 90-day anniversary of the Participant's Date of
       Termination (or, in the case of a Date of Termination occurring by reason
       of the Participant's Death or Disability, not later than the one-year
       anniversary following the Date of Termination).

ADJUSTMENTS. If the Board determines that, after the Effective Date, one or more
       transactions (including, without limitation, a stock split or
       combination) have occurred in which stock of the Company is issued,
       exchanged, or modified without receipt of additional

                                        2
<Page>

       consideration by the Company of money or property (but excluding
       consideration in the form of services), the Board shall adjust the number
       of shares of Stock subject to the SAR and shall adjust the Exercise Price
       to reflect such transaction.

WITHHOLDING. All deliveries and distributions under this Agreement are subject
       to withholding of all applicable taxes.

BENEFITS MAY NOT BE ASSIGNED. The interests of a Participant under this
       Agreement are not subject in any manner to anticipation, alienation,
       sale, transfer, assignment, pledge, encumbrance, attachment, or
       garnishment by creditors of the Participant or the Participant's
       beneficiary. The SAR is not transferable other than as designated by the
       Participant by will or by the laws of descent and distribution.

BENEFITS UNDER OTHER PLANS. Amounts payable to the Participant under this
       Agreement shall be disregarded for purposes of determining the benefits
       under any plan that is intended to be qualified under section 401(a) of
       the Internal Revenue Code of 1986 and any other plan or arrangement
       maintained by the Company or any Related Company, except as otherwise
       specifically provided to the contrary in such other plan or arrangement.

SAR NOT CONTRACT OF EMPLOYMENT. Neither this Agreement nor the SAR constitutes
       a contract of employment, and will not give the Participant the right to
       be retained in the employ of the Company or Related Company nor any right
       or claim to any benefit under the SAR, unless such right or claim has
       specifically accrued under the terms of this Agreement and the SAR.

NO RIGHTS AS STOCKHOLDER. Except in the case of this SAR being converted to an
       option (and then only with respect to shares acquired upon the exercise
       of the option), the Participant shall not have any rights of a
       stockholder with respect to the shares subject to the SAR.

NO GUARANTEE. Neither the Participant nor any other person shall, by reason
       of this Agreement, acquire any right in or title to any assets, funds or
       property of the Company or any Related Company whatsoever, including,
       without limitation, any specific funds, assets, or other property which
       the Company, in its sole discretion, may set aside in anticipation of a
       liability under this Agreement. The Participant shall have only a
       contractual right to the amounts, if any, payable under this Agreement,
       unsecured by any assets of the Company or any Related Company. Nothing
       contained in this Agreement shall constitute a guarantee by the Company
       that the assets of the Company shall be sufficient to pay any benefits to
       any person.

HEIRS AND SUCCESSORS. This Agreement shall be binding upon, and inure to the
       benefit of, the Company and its successors and assigns, and upon any
       person acquiring, whether by merger, consolidation, purchase of assets or
       otherwise, all or substantially all of the Company's assets and business.
       If any benefits deliverable to the Participant under this Agreement have
       not been delivered at the time of the Participant's death, such benefits
       shall be delivered to the Designated Beneficiary in accordance with the
       provisions of this Agreement. The "Designated Beneficiary" shall be the
       beneficiary or beneficiaries designated by the Participant in a writing
       filed with the Board in such form and at such

                                        3
<Page>

       time as the Board shall require. If a deceased Participant fails to
       designate a beneficiary, or if the Designated Beneficiary does not
       survive the Participant, any benefits distributable to the Participant
       shall be distributed to the legal representative of the estate of the
       Participant. If a deceased Participant designates a beneficiary and the
       Designated Beneficiary survives the Participant but dies before the
       complete distribution of benefits to the Designated Beneficiary under
       this Agreement, then any benefits distributable to the Designated
       Beneficiary shall be distributed to the legal representative of the
       estate of the Designated Beneficiary.

DISTRIBUTIONS TO DISABLED PERSONS. Notwithstanding the provisions of this
       Agreement to the contrary, if, in the opinion of the Board, the
       Participant or beneficiary is under a legal disability or is in any way
       incapacitated so as to be unable to manage his financial affairs, the
       Board may direct that payment be made to a relative or friend of such
       person for his benefit until claim is made by a conservator or other
       person legally charged with the care of his person or his estate, and
       such payment shall be in lieu of any such payment to the Participant or
       beneficiary. Thereafter, any benefits under this Agreement to which such
       Participant or beneficiary is entitled shall be paid to such conservator
       or other person legally charged with the care of his person or his
       estate.

APPLICABLE LAW. Except to the extent that not preempted by the laws of the
       United States of America, this Agreement shall be construed and
       administered with the laws of the state of New York; provided that no
       doctrine of choice of law shall be used to apply any law other than that
       of New York, and no defense, counterclaim or right of set-off given or
       allowed by the laws of any other state or jurisdiction, or arising out of
       the enactment, modification or repeal of any law, regulation, ordinance
       or decree of any foreign jurisdiction, shall be interposed in any action
       hereon.

AMENDMENT. This Agreement may be amended by written agreement of the Participant
       and the Company without the consent of any other person.

ADMINISTRATION. The authority to control and manage the operation and
       administration of this Agreement and the arrangement specified by this
       Agreement shall be vested in the Board. The Board will have the authority
       and discretion to interpret this Agreement, to establish, amend, and
       rescind any rules and regulations relating to this Agreement, and to make
       all other determinations that may be necessary or advisable for the
       administration of this Agreement. Any interpretation of this Agreement by
       the Board and any decision made by it under this Agreement is final and
       binding on all persons. Except to the extent prohibited by applicable
       law, the Board may allocate all or any portion of its responsibilities
       and powers to any one or more of its members and may delegate all or any
       part of its responsibilities and powers to any person or persons selected
       by it. Any such allocation or delegation may be revoked by the Board at
       any time. The Company and Related Companies shall furnish the Board with
       such data and information as it determines may be required for it to
       discharge its duties. The records of the Company and Related Companies as
       to the Participant's employment, termination of employment, leave of
       absence, reemployment and compensation shall be conclusive on all persons
       unless determined to be incorrect. The Participant and other persons
       entitled to benefits

                                        4

       information as the Board considers desirable to carry out the terms of
       this Agreement.

The vesting of the SAR shall be subject to the following:

<Page>

Notwithstanding the foregoing schedule, but subject to paragraph (b) below, the
       SAR shall become fully vested upon the date of a Public Offering or
       Change of Control that occurs on or before the Date of Termination. The
       vesting described in this paragraph (a) shall be deemed to occur
       immediately before the exercise of the SAR described in paragraph 3.

If, during any Vesting Period, an Event of Default occurs, then the number of
       Covered Shares that would otherwise vest on the last day of that Vesting
       Period shall instead be forfeited, and in no event shall the Participant
       be entitled to any amounts with respect to such Covered Shares by reason
       of exercise of the SAR, by reason of paragraph (a) above, or for any
       other reason.

If a Public Offering or Change of Control does not occur on or before the
       Participant's Date of Termination, and such Date of Termination occurs
       for reasons other than a Material Breach or Cause, or voluntary
       termination then all rights under the SAR that are not vested on the Date
       of Termination shall expire and all rights under the SAR that have vested
       prior to the Date of Termination shall be subject to repurchase by the
       Company under Section 7(a) of the Management Subscription Agreement,
       dated as of the date hereof, among the Company and certain employees of
       the Company or its subsidiaries. If a Public Offering or Change of
       Control does not occur on or before the Participant's Date of
       Termination, and such Date of Termination occurs by reason of a Material
       Breach, Cause or voluntary termination, then all rights under the SAR
       shall be forfeited on the Date of Termination.

EXERCISE OF SAR. The SAR shall be exercised with respect to the vested portion
       of the Covered Shares on the first to occur of a Public Offering or a
       Change of Control. (For the avoidance of doubt, it is recited here that
       the SAR shall not be exercised except as provided in the preceding
       sentence.) As soon as practicable after the exercise of the SAR with
       respect to a share of Stock, the Participant shall receive a cash payment
       from the Company which is equal to the excess of the Fair Market Value of
       a share of Stock on the date of exercise over the Exercise Price of one
       share of Stock. Notwithstanding the foregoing provisions of this
       paragraph 3, if the SAR would otherwise become exercisable in accordance
       with this paragraph 3 by reason of a Public Offering, and the
       Participant's Date of Termination has not occurred prior to the date of
       the Public Offering, then, in the sole discretion of the Board, the SAR
       may be canceled, provided that, at the time of the Public Offering, the
       Participant will be granted an option to purchase shares of Stock equal
       to the number of Covered Shares. Such option (i) shall be fully
       exercisable at and after the granting of the option (until expiration
       described in clause (iii) below) with respect to all of the Covered
       Shares, (ii) shall have a per-share exercise price equal to the exercise
       price of the SAR; and (iii) shall expire on the earlier of the ten-year
       anniversary of the Grant Date (as defined in this Agreement), but not
       event later than the 90-day anniversary of the Participant's Date of
       Termination (or, in the case of a Date of Termination occurring by reason
       of the Participant's Death or Disability, not later than the one-year
       anniversary following the Date of Termination).

ADJUSTMENTS. If the Board determines that, after the Effective Date, one or more
       transactions (including, without limitation, a stock split or
       combination) have occurred in which stock of the Company is issued,
       exchanged, or modified without receipt of additional

                                        2
<Page>

       consideration by the Company of money or property (but excluding
       consideration in the form of services), the Board shall adjust the number
       of shares of Stock subject to the SAR and shall adjust the Exercise Price
       to reflect such transaction.

WITHHOLDING. All deliveries and distributions under this Agreement are subject
       to withholding of all applicable taxes.

BENEFITS MAY NOT BE ASSIGNED. The interests of a Participant under this
       Agreement are not subject in any manner to anticipation, alienation,
       sale, transfer, assignment, pledge, encumbrance, attachment, or
       garnishment by creditors of the Participant or the Participant's
       beneficiary. The SAR is not transferable other than as designated by the
       Participant by will or by the laws of descent and distribution.

BENEFITS UNDER OTHER PLANS. Amounts payable to the Participant under this
       Agreement shall be disregarded for purposes of determining the benefits
       under any plan that is intended to be qualified under section 401(a) of
       the Internal Revenue Code of 1986 and any other plan or arrangement
       maintained by the Company or any Related Company, except as otherwise
       specifically provided to the contrary in such other plan or arrangement.

SAR NOT CONTRACT OF EMPLOYMENT. Neither this Agreement nor the SAR constitutes
       a contract of employment, and will not give the Participant the right to
       be retained in the employ of the Company or Related Company nor any right
       or claim to any benefit under the SAR, unless such right or claim has
       specifically accrued under the terms of this Agreement and the SAR.

NO RIGHTS AS STOCKHOLDER. Except in the case of this SAR being converted to an
       option (and then only with respect to shares acquired upon the exercise
       of the option), the Participant shall not have any rights of a
       stockholder with respect to the shares subject to the SAR.

NO GUARANTEE. Neither the Participant nor any other person shall, by reason of
       this Agreement, acquire any right in or title to any assets, funds or
       property of the Company or any Related Company whatsoever, including,
       without limitation, any specific funds, assets, or other property which
       the Company, in its sole discretion, may set aside in anticipation of a
       liability under this Agreement. The Participant shall have only a
       contractual right to the amounts, if any, payable under this Agreement,
       unsecured by any assets of the Company or any Related Company. Nothing
       contained in this Agreement shall constitute a guarantee by the Company
       that the assets of the Company shall be sufficient to pay any benefits to
       any person.

HEIRS AND SUCCESSORS. This Agreement shall be binding upon, and inure to the
       benefit of, the Company and its successors and assigns, and upon any
       person acquiring, whether by merger, consolidation, purchase of assets or
       otherwise, all or substantially all of the Company's assets and business.
       If any benefits deliverable to the Participant under this Agreement have
       not been delivered at the time of the Participant's death, such benefits
       shall be delivered to the Designated Beneficiary in accordance with the
       provisions of this Agreement. The "Designated Beneficiary" shall be the
       beneficiary or beneficiaries designated by the Participant in a writing
       filed with the Board in such form and at such

                                        3
<Page>

       time as the Board shall require. If a deceased Participant fails to
       designate a beneficiary, or if the Designated Beneficiary does not
       survive the Participant, any benefits distributable to the Participant
       shall be distributed to the legal representative of the estate of the
       Participant. If a deceased Participant designates a beneficiary and the
       Designated Beneficiary survives the Participant but dies before the
       complete distribution of benefits to the Designated Beneficiary under
       this Agreement, then any benefits distributable to the Designated
       Beneficiary shall be distributed to the legal representative of the
       estate of the Designated Beneficiary.

DISTRIBUTIONS TO DISABLED PERSONS. Notwithstanding the provisions of this
       Agreement to the contrary, if, in the opinion of the Board, the
       Participant or beneficiary is under a legal disability or is in any way
       incapacitated so as to be unable to manage his financial affairs, the
       Board may direct that payment be made to a relative or friend of such
       person for his benefit until claim is made by a conservator or other
       person legally charged with the care of his person or his estate, and
       such payment shall be in lieu of any such payment to the Participant or
       beneficiary. Thereafter, any benefits under this Agreement to which such
       Participant or beneficiary is entitled shall be paid to such conservator
       or other person legally charged with the care of his person or his
       estate.

APPLICABLE LAW. Except to the extent that not preempted by the laws of the
       United States of America, this Agreement shall be construed and
       administered with the laws of the state of New York; provided that no
       doctrine of choice of law shall be used to apply any law other than that
       of New York, and no defense, counterclaim or right of set-off given or
       allowed by the laws of any other state or jurisdiction, or arising out of
       the enactment, modification or repeal of any law, regulation, ordinance
       or decree of any foreign jurisdiction, shall be interposed in any action
       hereon.

AMENDMENT. This Agreement may be amended by written agreement of the Participant
       and the Company without the consent of any other person.

ADMINISTRATION. The authority to control and manage the operation and
       administration of this Agreement and the arrangement specified by this

       and discretion to interpret this Agreement, to establish, amend, and
       rescind any rules and regulations relating to this Agreement, and to make
       all other determinations that may be necessary or advisable for the
       administration of this Agreement. Any interpretation of this Agreement by
       the Board and any decision made by it under this Agreement is final and
       binding on all persons. Except to the extent prohibited by applicable
       law, the Board may allocate all or any portion of its responsibilities
       and powers to any one or more of its members and may delegate all or any
       part of its responsibilities and powers to any person or persons selected
       by it. Any such allocation or delegation may be revoked by the Board at
       any time. The Company and Related Companies shall furnish the Board with
       such data and information as it determines may be required for it to
       discharge its duties. The records of the Company and Related Companies as
       to the Participant's employment, termination of employment, leave of
       absence, reemployment and compensation shall be conclusive on all persons
       unless determined to be incorrect. The Participant and other persons
       entitled to benefits

                                        4
