                            (LIQUIDITY EVENT OPTION)

            THIS AGREEMENT (the "Agreement"), is made effective as of the _____
day of _____, 200_, (hereinafter called the "Date of Grant"), between Vanguard
Health Systems, Inc., a Delaware corporation (hereinafter called the "Company"),

            WHEREAS, the Company has adopted the Vanguard Health Systems, Inc.
2004 Stock Incentive Plan (the "Plan"), which Plan is incorporated herein by
reference and made a part of this Agreement. Capitalized terms not otherwise
defined herein shall have the same meanings as in the Plan; and

            WHEREAS, the Committee has determined that it would be in the best
interests of the Company and its shareholders to grant the option provided for
herein (the "Option") to the Participant pursuant to the Plan and the terms set
forth herein.

            NOW THEREFORE, in consideration of the mutual covenants hereinafter
set forth, the parties agree as follows:

            1. Grant of the Option. The Company hereby grants to the Participant
the right and option (the "Option") to purchase, on the terms and conditions
hereinafter set forth, all or any part of an aggregate of ____ Shares, subject
to adjustment as set forth in the Plan. The purchase price of the Shares subject
to the Option shall be $______ per Share (the "Option Price"). The Option is
intended to be a non-qualified stock option, and is not intended to be treated
as an option that complies with Section 422 of the Internal Revenue Code of

            (a) Subject to the Participant's continued Employment with the
Company, the Option shall vest and become exercisable with respect to one
hundred percent (100%) of the Shares initially covered by the Option on the
eighth anniversary of the Date of Grant.

            At any time, the portion of the Option which has become vested and
exercisable as described above (or pursuant to Section 2(c) below) is
hereinafter referred to as the "Vested Portion."

            (b) If the Participant's Employment with the Company is terminated
for any reason, the Option shall, to the extent not then vested, be canceled by
the Company without

consideration and the Vested Portion of the Option shall remain exercisable for
the period set forth in Section 3(a).

            (c) Notwithstanding any other provisions of this Agreement to the
contrary, in the event of a Liquidity Event the Option shall, to the extent not
then vested and not previously canceled, immediately become fully vested and
exercisable.

            For purposes of this Section 2(c), the following definitions shall

(ii) any trust established solely for the exclusive benefit of such natural
person or any of the Persons referred to in the foregoing clause (i).

            "Law" means any statute, law, regulation, ordinance, rule,

market value (measured at the time of receipt) in excess of $2,500 per Security

            (i) the tenth anniversary of the Date of Grant;

            (ii) one year following the date of the Participant's termination of
      Employment due to death or "Disability"; and

            (iii) 90 days following the date of the Participant's termination of
      Employment for any reason other than due to the Participant's death or
      Disability; provided, however, if Section 3(b)(ii) of this Agreement would
      otherwise preclude the exercise of the Option following the termination of
      Employment, the first day of the 90 day period under this Section
      3(a)(iii) shall commence on the first day of the completion of any
      registration or qualification of the Option or Shares in accordance with
      Section 3(b)(ii) of this Agreement.

            For purposes of this Agreement:

            "Disability" shall mean "disability" as defined in any employment

            (i) Subject to Section 3(a), the Vested Portion of the Option may be

      notice of intent to so exercise; provided that, the Option may be
      exercised with respect to whole Shares only. Such

<PAGE>
                                                                               4

      notice shall specify the number of Shares for which the Option is being
      exercised and shall be accompanied by payment in full of the Option Price.
      The payment of the Option Price may be made at the election of the
      Participant (i) in cash or its equivalent (e.g., by check), (ii) to the
      extent permitted by the Committee, in Shares having a Fair Market Value
      equal to the aggregate Option Price for the Shares being purchased and
      satisfying such other requirements as may be imposed by the Committee;
      provided, that such Shares have been held by the Participant for no less
      than six 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), (iii) partly in cash and, to
      the extent permitted by the Committee, partly in such Shares or (iv) if
      there is a public market for the Shares at such time, through the delivery
      of irrevocable instructions to a broker to sell Shares obtained upon the
      exercise of the Option and to deliver promptly to the Company an amount
      out of the proceeds of such Sale equal to the aggregate option price for
      the Shares being purchased. No Participant shall have any rights to
      dividends or other rights of a stockholder with respect to Shares subject
      to an Option until the Participant has given written notice of exercise of
      the Option, paid in full for such Shares and, if applicable, has satisfied
      any other conditions imposed by the Committee pursuant to the Plan.

            (ii) Notwithstanding any other provision of the Plan or this
      Agreement to the contrary, the Option may not be exercised prior to the
      completion of any registration or qualification of the Option or the
      Shares under applicable state and federal securities or other laws, or
      under any ruling or regulation of any governmental body or national
      securities exchange that the Committee shall in its sole discretion
      determine to be necessary or advisable.

            (iii) Upon the Company's determination that the Option has been
      validly exercised as to any of the Shares, the Company shall issue
      certificates in the Participant's name for such Shares. However, the
      Company shall not be liable to the Participant for damages relating to any
      delays in issuing the certificates to him, any loss of the certificates,
      or any mistakes or errors in the issuance of the certificates or in the
      certificates themselves.

            (iv) In the event of the Participant's death, the Vested Portion of
      the Option shall remain exercisable by the Participant's executor or
      administrator, or the person or persons to whom the Participant's rights
      under this Agreement shall pass by will or by the laws of descent and
      distribution as the case may be, to the extent set forth in Section 3(a).
      Any heir or legatee of the Participant shall take rights herein granted
      subject to the terms and conditions hereof.

            (v) As a condition to exercising the Option, the Participant shall
      become a party to the Stockholders Agreement.

            4. No Right to Continued Employment. The granting of the Option
evidenced hereby and this Agreement shall impose no obligation on the Company or
any Affiliate to continue the Employment of the Participant and shall not lessen
or affect the Company's or its Affiliate's right to terminate the Employment of
such Participant.

            5. Legend on Certificates. The certificates representing the Shares
purchased by exercise of the Option shall be subject to such stop transfer
orders and other restrictions as the

<PAGE>
                                                                               5

Committee may deem advisable under the Plan or the rules, regulations, and other
requirements of the Securities and Exchange Commission, any stock exchange upon
which such Shares are listed, and any applicable Federal or state laws, and the
Committee may cause a legend or legends to be put on any such certificates to
make appropriate reference to such restrictions.

            6. Transferability. The Option may not be assigned, alienated,
pledged, attached, sold or otherwise transferred or encumbered by the
Participant otherwise than by will or by the laws of descent and distribution,
and any such purported assignment, alienation, pledge, attachment, sale,
transfer or encumbrance shall be void and unenforceable against the Company or
any Affiliate; provided that the designation of a beneficiary shall not
constitute an assignment, alienation, pledge, attachment, sale, transfer or
encumbrance. No such permitted transfer of the Option to heirs or legatees of
the Participant shall be effective to bind the Company unless the Committee
shall have been furnished with written notice thereof and a copy of such
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 hereof. During the Participant's lifetime, the Option is exercisable
only by the Participant.

            7. Withholding. The Participant may be required to pay to the
Company or any Affiliate and the Company shall have the right and is hereby
authorized to withhold from any payment due or transfer made under the Option or
under the Plan or from any compensation or other amount owing to a Participant
the amount (in cash, Shares, other securities, other Awards or other property)
of any applicable withholding taxes in respect of the Option, its exercise or
any payment or transfer under or with respect to the Option or the Plan and to
take such other action as may be necessary in the opinion of the Committee to
satisfy all obligations for the payment of such withholding taxes.

            8. Securities Laws. Upon the acquisition of any Shares pursuant to
the exercise of the Option, the Participant will make or enter into such written
representations, warranties and agreements as the Committee may reasonably
request in order to comply with applicable securities laws or with this
Agreement.

            9. Notices. Any notice necessary under this Agreement shall be
addressed to the Company in care of its Secretary at the principal executive
office of the Company and to the Participant at the address appearing in the
personnel records of the Company for the Participant or to either party at such
other address as either party hereto may hereafter designate in writing to the
other. Any such notice shall be deemed effective upon receipt thereof by the
addressee.

            10. Choice of Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO CONFLICTS
OF LAWS.

            11. Option Subject to Plan and Stockholders Agreement. By entering
into this Agreement the Participant agrees and acknowledges that the Participant
has received and read a copy of the Plan and the Stockholders Agreement. The
Option is subject to the Plan and the Stockholders Agreement. The terms and
provisions of the Plan and the Stockholders Agreement as it may be amended from
time to time are hereby incorporated herein by reference. In the event of a
conflict between any term or provision contained herein and a term or provision
of the Plan or the Stockholders Agreement, the applicable terms and provisions
of the Plan or the

<PAGE>
                                                                               6

Stockholders Agreement, as applicable will govern and prevail. In the event of a
conflict between any term or provision of the Plan and any term or provision of
the Stockholders Agreement, the applicable terms and provisions of the

            12. Signature in Counterparts. This Agreement may be signed in
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

            IN WITNESS WHEREOF, the parties hereto have executed this Agreement.

                                          VANGUARD HEALTH SYSTEMS, INC.

such Directors or for any action taken pursuant to any consent given or vote
cast by it or other action taken by it, and the Management Representative's
powers herein shall be discretionary and any of them may be exercised from time

the parties hereto other than pursuant to this Agreement.

      (d) The powers granted pursuant to this Section 1.1, and the proxy granted

have agreed in writing to be bound as an "Employee" by the terms of this
Section.

      (f) The Management Representative accepts his appointment as proxy and
agent and agrees to serve in such capacity pursuant to the terms of this Section

imposed in relation thereto and any other expenses in connection therewith. The
provisions of this Section 3.3(c) are exclusive and shall preclude (to the
extent permissible under applicable law) all other rights and remedies with
respect to the replacement or payment of mutilated, destroyed, lost or stolen

      Section 3.4. Company Right of First Refusal.

      (a) After the fifth anniversary of the Effective Date and until the
earlier of a Change of Control or a Qualified IPO (the "ROFR Period"), the
Company shall have a right of first refusal with respect to any proposed
Transfer of Shares by any Employee (a "Transferring Shareholder"), and any
Transferring Shareholder must first comply with the provisions of this Section
3.4.

      (b) At any time a Transferring Shareholder proposes to make a bona fide
Transfer of Shares during the ROFR Period (other than (i) a Transfer pursuant to
clause (i) of Section 3.1(b), (ii) pursuant to the Registration Rights Agreement
or (iii) pursuant to Section 3.5 or 3.6), and such Transferring Shareholder has
received a bona fide arm's length offer (the "Offer") to purchase all or any
portion of its Shares (the "Offered Securities") from any Person (the "Offeror")
which the Transferring Shareholder wishes to accept, such Transferring
Shareholder shall cause the Offer to be reduced to writing and shall notify the
Company in writing of its wish to accept the Offer (the "Offering Notice").

      (c) Offering Notice. The Offering Notice shall contain an irrevocable
offer to sell the Offered Securities to the Company at a price equal or
equivalent (as determined in the manner set forth in Section 3.4(d)(i) below) to
the price contained in, and otherwise on the same terms and conditions of, the
Offer and shall be accompanied by a copy of the Offer (which shall identify the
Offeror).

      (d) Company's Option; Exercise.

                  (i) For a period of 20 days after the date upon which the
            Company shall have received the Offering Notice (the "Company Option
            Period"), the Company shall have the right to elect to purchase all
            (but not less than all) of the Offered Securities either (A) at the
            same price and on the same terms and conditions as the Offer or (B)
            if the Offer includes any consideration other than cash, then at the
            sole option of the Company, at the equivalent cash price, determined
            in good faith by the Board and reasonably agreed to by the
            Transferring Shareholder. If the Company does not elect to purchase
            all of the Offered Securities pursuant to this Section 3.4(d), then
            the Transferring Shareholder may sell all of the Offered Securities
            to the Offeror in accordance with Section 3.4(f).

                  (ii) The right of the Company to purchase the Offered
            Securities under Section 3.4(d)(i) shall be exercisable by
            delivering written notice of the exercise thereof, prior to the
            expiration of the Company Option Period, to the Transferring
            Shareholder. The failure of the Company to deliver such a notice to
            the Transferring Shareholder within the Company Option Period to the
            Transferring Shareholder shall be deemed to be a waiver of the
            Company's rights under Section 3.4(d)(i).

                                      -6-
<PAGE>

      (e) Closing. The closing of the purchase of Offered Securities subscribed
for by the Company under Section 3.4(d) shall be held at the executive office of
the Company at 11:00 a.m., local time, no later than 30 days after the Company's
election to purchase the Offered Securities pursuant to Section 3.4(d) is
delivered to the Transferring Shareholder or at such other time and place as the
parties to the transaction may agree; provided that if such sale is subject to
any prior regulatory approval, then such 30-day period shall be extended until
the expiration of ten days after all such approvals shall have been received,
but in no event shall such period be extended for more than an additional 60
days without the consent of the Transferring Shareholder. At such closing, the
Transferring Shareholder shall deliver certificates representing the Offered
Securities, duly endorsed for transfer and accompanied by all requisite transfer
taxes, if any, and such Offered Securities shall be free and clear of any liens,
and the Transferring Shareholder shall so represent and warrant, and shall
further represent and warrant that it is the sole beneficial and record owner of
such Offered Securities with the full right, power and authority to convey the
Offered Securities to the Company. The Company shall deliver at the closing
payment in full in immediately available funds for the Offered Securities
purchased by it. At such closing, all of the parties to the transaction shall
execute such additional documents as are otherwise necessary or appropriate.

      (f) Sale to the Offeror. If the Company does not elect to purchase all of
the Offered Securities under Section 3.4(d), or if the Company does so elect but
the regulatory approvals necessary to consummate such purchase are not obtained
within the time periods referred to in Section 3.4(e), then in either such case
the Transferring Shareholder may sell all (but not less than all) of the Offered
Securities to the Offeror on terms and conditions no less favorable to the
Transferring Shareholder than those set forth in the Offering Notice; provided,
however, that such sale is bona fide and made pursuant to a contract entered
into not later than 60 days after the earlier to occur of (i) the waiver by the
Company of its option to purchase the Offered Securities and (ii) the expiration
of the Company Option Period (the "Contract Date"); and provided, further, that
such sale shall not be consummated unless and until (A) such Offeror shall
represent in writing to the Company that it is aware of the rights and
obligations of the Company contained in this Agreement and (B) prior to the
purchase by such Offeror of such Offered Securities, such Offeror shall become a
party to this Agreement and shall agree to be bound by the terms and conditions
hereof to the same extent as the Transferring Shareholder. If such sale is not
consummated within 60 days after the Contract Date for any reason, then the
restrictions provided for herein shall again become effective, and no Transfer
of such Offered Securities may be made thereafter by the Transferring
Shareholder without again complying with this Section 3.4; provided that if such
sale is subject to any prior regulatory approval, then such 60-day period shall
be extended until the expiration of ten days after all such approvals shall have
been received, but in no event shall such period be extended for more than an
additional 120 days without the consent of the Company.

      Section 3.5. Tag-Along Rights.

      (a) Prior to a Qualified IPO, if Blackstone proposes to Transfer, in a
single transaction or a series of related transactions, any Securities owned by
it to any Person (other than (i) a Transfer to an Affiliate of Blackstone or
(ii) a Transfer pursuant to the Registration Rights Agreement) (a "Tag-Along
Purchaser"), then, unless Blackstone is entitled to give and does give a
Drag-Along Notice pursuant to Section 3.6(b) hereof and the Drag-Along Sale

                                      -7-
<PAGE>
that is the subject of such Drag-Along Notice is consummated within the
applicable time period referred to in Section 3.6(c), Blackstone shall first
provide written notice to the Shareholders, which notice (the "Tag-Along
Notice") shall include: (i) the maximum number of Securities proposed to be
Transferred (the "Tag-Along Securities"); (ii) the purchase price per security
(the "Tag-Along Price") for the Tag-Along Securities; (iii) any other material
terms and conditions of such sale, including the proposed transfer date and (iv)
the proposed form of agreement. Each Shareholder (and any other Person that
holds similar tag along RIGHTS) that has been provided with the Tag-Along Notice
(each, a "Tag-Along Shareholder") shall have the right to require Blackstone to
include in such Transfer to such Tag-Along Purchaser, upon the terms set forth
in the Tag-Along Notice, up to the aggregate number of Securities which are held
by such Tag-Along Shareholder multiplied by a fraction, the numerator of which
is the aggregate number of Securities proposed to be Transferred by Blackstone
as reflected in the Tag-Along Notice and the denominator of which is the total
number of Securities which are held by Blackstone (the "Tag-Along Fraction"). If
the number of Securities elected to be Transferred by the Tag-Along Shareholder
together with the number of Securities proposed to be Transferred by Blackstone
is greater than the number of Tag-Along Securities specified in the Tag-Along
Notice, then the number of Securities being sold by each such seller (including
Blackstone) shall be reduced such that the applicable seller shall be entitled
to (and obligated to) sell only its pro rata share of Securities (based on the
aggregate number of Securities held by such seller to the total number of
Securities held by all of such electing sellers).

      (b) The tag-along rights provided by this Section 3.5 must be exercised by
any Tag-Along Shareholder wishing to sell its Securities within 15 days
following the date of delivery of the Tag-Along Notice (the "Election Period"),
by delivery of a written notice to the Company indicating such Tag-Along
Shareholder's wish to irrevocably exercise its rights and specifying the number
of Securities it wishes to sell. The failure of a Tag-Along Shareholder to
respond within such 15-day period shall be deemed to be a waiver of such
Tag-Along Shareholder's rights under Section 3.5.

      (c) In connection with any Transfer pursuant to this Section 3.5, each
Tag-Along Shareholder shall make to the Tag-Along Purchaser the same
representations, warranties, covenants, indemnities and agreements as Blackstone
makes in connection with such Transfer (except that in the case of
representations, warranties, covenants, indemnities and agreements pertaining
specifically to Blackstone, each Tag-Along Shareholder shall make the comparable
representations, warranties, covenants, indemnities and agreements pertaining
specifically to itself); provided that all representations, warranties and
indemnities shall be made by Blackstone and such Tag-Along Shareholder severally
and not jointly and that the liability of Blackstone and such Tag-Along
Shareholder thereunder shall be borne by each of them on a pro rata basis based
on the number of Securities which are Transferred. The Tag-Along Shareholders
shall receive the same type and amount of consideration per Security as is paid
or delivered to Blackstone in such Transfer. Each Tag-Along Shareholder shall be
responsible for its proportionate share of the costs and expenses incurred in
connection with such Transfer to the extent not paid or reimbursed by the
Company or the Tag-Along Purchaser.

      Section 3.6. Right to Drag-Along.

      (a) Prior to a Qualified IPO, any bona fide Transfer proposed by
Blackstone of a majority of the outstanding Securities to any Person (other than
to an Affiliate of Blackstone) shall be subject to the provisions of this
Section 3.6.

      (b) If Blackstone enters into a definitive agreement for a Transfer which
is subject to this Section 3.6 (the "Drag-Along Sale"), then Blackstone may,
within 15 days following the execution of such agreement send written notice
(the "Drag-Along Notice") to each Shareholder notifying them that they will be
required to Transfer the number of Shares held by such Shareholder multiplied by
a fraction (the "Drag-Along Fraction") the numerator of which is the aggregate
number of Securities proposed to be sold by Blackstone as reflected in the
Drag-Along Notice and the denominator of which is the total number of Securities
which are held by Blackstone (the "Dragged Securities"). Such Drag-Along Notice
shall set forth the name of the proposed transferee, the proposed amount and
form of consideration and the other terms and conditions of the offer, including
a copy of the definitive agreement relating to the Drag-Along Sale. Upon receipt
of a Drag-Along Notice, each Shareholder shall be required to Transfer its
Dragged Securities to such proposed Transferee at the same price and on the same
terms as those governing the Drag-Along Sale, including making the same
representations, warranties, covenants, indemnities and agreements that
Blackstone agrees to make (except that, in the case of representations and
warranties pertaining specifically to Blackstone, the Shareholders shall make
the comparable representations and warranties pertaining specifically to
itself); provided that all representations, warranties and indemnities shall be
made by each Shareholder severally and not jointly and that the liability of
each Shareholder thereunder shall be borne by each of them on a pro rata basis
based on the number of Securities which are Transferred. Each Shareholder shall
be responsible for its proportionate share of the costs and expenses incurred in
connection with such Transfer to the extent not paid or reimbursed by the
Company or the purchaser.

      (c) If the Drag-Along Sale is not consummated within 180 days of the date
of the Drag-Along Notice, then the provisions of this Section 3.6 shall
terminate and be of no further force and effect with respect to such Drag-Along
Sale, but all other provisions of this Agreement (including Section 3.5) shall
continue to apply to the proposed Transfer that was the subject of such
Drag-Along Sale; provided that, if such Drag-Along Sale is subject to prior
regulatory approval, such 180-day period shall be extended until the expiration
of 30 days after all such approvals have been received, but in no event later
than 365 days following the date of the Drag-Along Notice.

                                   ARTICLE IV

                  CERTAIN PROVISIONS APPLICABLE TO SHAREHOLDERS

      Section 4.1. Company Call Option.

      (a) If an Employee's Services to the Company and its Subsidiaries
terminate for any reason (a "Termination Event"), the Company shall have the
right but not the obligation to purchase, from time to time after such

                                      -9-
<PAGE>
Termination Event, for a period of 181 days following the later of (x)
termination of such Employee's Services and (y) with respect to Shares received
upon the exercise of an option, the date such option is exercised (the "Call
Option Period"), the Shares held by such Employee. To exercise such purchase
right with respect to an Employee, the Company shall deliver to such Employee
prior to the expiration of the Call Option Period a written notice specifying
the number of Shares with respect to which the Company has elected to exercise
such purchase right, whereupon such Employee shall be required to sell to the
Company, the Shares specified in such notice, at a price per Share equal to the
applicable purchase price determined pursuant to Section 4.1(c).

      (b) If upon expiration of the Call Option Period, the Company has not
purchased all of a terminated Employee's Shares, the Company shall on or before
the expiration of the Call Option Period provide written notice to all of the
Senior Management Investors and Blackstone and MSCP (collectively, the "Other
Investors") of (i) its decision not to purchase some or all of such Shares and
(ii) the amount of such Shares which the Company did not purchase, and the Other
Investors shall have the right to purchase all or a portion of such remaining
Shares at a price per Share equal to the applicable purchase price determined
pursuant to Section 4.1(c). The Other Investors' rights to purchase such Shares
and such Employee's corresponding obligation to sell such Shares shall terminate
on the 30th day following the expiration of the Call Option Period. Each of the
Other Investors that elects to exercise such purchase right shall provide
written notice to the Company prior to the 30th day following the expiration of
the Call Option Period specifying the amount of such Shares it wishes to
purchase (and, if the aggregate number of Shares specified in such notices
exceeds the number of Shares available, the number of Shares which each Other
Investor shall be entitled to purchase shall be reallocated in proportion to
each such Other Investor's Ownership Percentage). Upon receipt of the Other
Investors' notice, the Company will notify such Employee of the Other Investors'
elections and such Employee will be obligated to sell to the Other Investors the
number of such Shares determined in accordance with this Section 4.1(b).

      (c) Upon a termination of an Employee's Services by the Company for Cause,
the purchase price for the Shares will be the lower of Cost and the Fair Market
Value of the Shares determined, in the case of a purchase by the Company
pursuant to 4.1(a), as of the date on which the Company exercised its call right
pursuant to Section 4.1(a) or, in the case of a purchase by an Other Investor
pursuant to 4.1(b), as of the 30th day following the expiration of the
applicable Call Option Period (such date, the "Call Price Determination Date").
Upon a termination of an Employee's Services to the Company for any reason other
than a termination by the Company for Cause (including a termination by an
Employee for Good Reason), the purchase price for the Shares will be Fair Market
Value of the Shares determined as of the Call Price Determination Date.

      (d) The closing of the purchase of the Shares pursuant to Section 4.1(a)
or 4.1(b) shall occur at such time and place as the parties to such purchase
shall agree, and in any event within 45 days of the Call Price Determination
Date; provided that if such purchase is subject to any prior regulatory
approval, then such 45-day period shall be extended until the expiration of ten
days after all such approvals shall have been received; provided further that if
all such approvals are not obtained within 120 days of the expiration of such
45-day period, then the provisions of this Section 4.1 shall terminate and be

                                      -10-
<PAGE>
no further force and effect with respect to such Shares. At such closing, the
Employee shall deliver Stock Certificates, representing such Shares, duly
endorsed for transfer and accompanied by all requisite transfer taxes, if any,
and such Shares shall be free and clear of any liens, and the Employee selling
such Shares shall so represent and warrant, and shall further warrant that it is
the sole beneficial and record owner of such Shares with the full right, power
and authority to convey such Shares to the purchaser. At such closing, all of
the parties to the transaction shall execute such additional documents as are
otherwise necessary or appropriate. The Shares may be purchased (i) by delivery
of funds deposited into an account designated by the Employee selling such
Shares, a bank cashier's check or a certified check for the purchase price or
(ii) if the purchaser is the Company and it is prohibited from paying cash by
any of its financing arrangements, then by a note of the Company payable in
installments over a period of up to five (5) years from the date of issuance of
such note, having a principal amount equal to the applicable purchase price,
bearing interest at the prime lending rate in effect from time to time (which
note shall be a negotiable instrument under applicable Law). The Company shall
notify the Employees in writing of the method by which it has elected to
purchase the Shares at least 10 days prior to the closing of such purchase.

      (e) Notwithstanding anything to the contrary elsewhere herein, the Company
shall not be obligated to purchase any Shares at any time pursuant to this
Section 4.1, regardless of whether it has delivered a notice of its election to
purchase any such Shares, (i) to the extent that the purchase of such Shares
(together with any other purchases of Shares pursuant to this Section 4.1, or
pursuant to similar provisions in any other agreements with other investors, of
which the Company has at such time been given or has given notice), the purchase
of such Shares by the Company would result (y) in a violation of any Law or (z)
after giving effect thereto (including any dividends or other distributions or
loans from a Subsidiary of the Company to the Company in connection therewith),
in a Financing Default, (ii) if immediately prior to such purchase of Shares,
there exists a Financing Default which prohibits such purchase (including any
dividends or other distributions or loans from a Subsidiary of the Company to
the Company in connection therewith), or (iii) if the Company does not have
funds available to effect such purchase of Shares. The Company shall within 15
days of learning of any such fact so notify the Shareholders in writing that it
is not obligated to purchase such Shares, whereupon Sections 4.1(b) and 4.1(c)
shall apply to such Shares as if the Company had never delivered a notice
electing to purchase such Shares (except that each reference to "the 30th day
following the expiration of the Call Option Period" in Section 4.1(b) shall be

Determination Date" shall be deemed modified in a corresponding manner).

      (f) The Fair Market Value for the Shares to be purchased under this

of the Services of the relevant Employee by the Company without Cause, by the
relevant Employee with Good Reason or as a result of the death or disability of
the relevant Employee, but with a 25% discount applied to reflect minority
interest and illiquidity in the event of a termination by the relevant Employee
without Good Reason prior to the fifth anniversary of the Effective Date). If
the relevant Employee disagrees with the Board's determination of the Fair
Market Value, he or she may require the Company to retain an Independent

                                      -11-
<PAGE>
Appraiser to determine the Fair Market Value (it being understood that the
Independent Appraiser shall be instructed in its determination of Fair Market
Value to apply any discount applicable pursuant to the preceding sentence). The
determination of Fair Market Value by the Independent Appraiser shall be final
and binding upon the Company and such Employee. The Company will bear the cost
of such appraisal unless the Fair Market Value as determined by the Independent
Appraiser is less than 110% of the Board's determination of Fair Market Value
pursuant to the first sentence of this paragraph, in which case the Employee
will bear the cost of the appraisal. Notwithstanding the foregoing, following a
Qualified IPO, Fair Market Value for the Shares for purposes of this Section 4.1
shall in all cases be based on the Public Share FMV.

      Section 9.3. Governing Law; Submission to Jurisdiction; Waiver of Jury
Trial.

      (a) THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY,
THE LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES
WHICH WOULD RESULT IN THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

      (b) The parties hereto agree that any suit, action or proceeding seeking
to enforce any provision of, or based on any matter arising out of or in
connection with, this Agreement or the transactions contemplated hereby shall be
brought in any federal court located in the State of Delaware or any Delaware
state court, and each of the parties hereby irrevocably consents to the
exclusive jurisdiction of such courts (and of the appropriate appellate courts
therefrom) in any such suit, action or proceeding and irrevocably waives, to the
fullest extent permitted by law, any objection that it may now or hereafter have
to the laying of the venue of any such suit, action or proceeding in any such
court or that any such suit, action or proceeding brought in any such court has
been brought in an inconvenient forum. Process in any such suit, action or
proceeding may be served on any party anywhere in the world, whether within or
without the jurisdiction of any such court. Without limiting the foregoing, each
party agrees that service of process on such party as provided in Section 9.2
shall be deemed effective service of process on such party.

      (c) EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT
TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

      Section 9.4. Entire Agreement This Agreement and the Registration Rights
Agreement set forth the entire understanding and agreement of the parties hereto
and supersede any and all other understandings, term sheets, negotiations

                                      -23-
<PAGE>
or agreements between the parties hereto relating to the subject matter of this
Agreement and the Registration Rights Agreement.

      Section 9.5. Counterparts. This Agreement may be executed in counterparts,
each of which shall be deemed an original, and all of which together shall
constitute a single agreement.

      Section 9.6. Severability. In the event that any one or more of the
provisions contained in this Agreement shall for any reason be held to be
invalid, illegal or unenforceable, the same shall not affect any other provision
of this Agreement, but this Agreement shall be construed in a manner which, as
nearly as possible, reflects the original intent of the parties.

      Section 9.7. Amendment and Modification. This Agreement may be amended or
modified only by a written instrument signed by the Company, Holdings,
Blackstone and the Employees which own Shares representing at least a majority
of the voting power represented by all Shares owned by all Employees (it being
assumed for the purposes of this Section 9.7 only that the foregoing clause "all
Shares owned by all Employees" means all Shares actually owned by all Employees
as well as all Shares which would be owned by all Employees if they exercised
all of their outstanding options exercisable for the purchase of Shares).

      Section 9.8. Waiver. Any party hereto may (i) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in any document delivered pursuant hereto, and (iii)
waive compliance with any of the agreements or conditions contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed by the party granting
such waiver but such waiver or failure to insist upon strict compliance with
such representation or warranty, obligation, covenant, agreement or condition
shall not operate as a waiver of, or estoppel with respect to, any subsequent or
future failure.

      Section 9.9. Further Assurances. Subject to the terms and conditions of
this Agreement, each of the parties hereto will use its reasonable efforts to
take, or cause to be taken, all actions, and to do, or cause to be done, all
things necessary, proper or advisable under applicable Laws and regulations, to
consummate and make effective the provisions of this Agreement.

      Section 9.10. Sections, Exhibits. References to a section are, unless
otherwise specified, to one of the sections of this Agreement and references to
an "Exhibit" is, unless otherwise specified, to one of the exhibits attached to
this Agreement.

      Section 9.11. Specific Enforcement. The parties hereto acknowledge and
agree that irreparable damage would occur in the event that any of the
provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. It is accordingly agreed that the
parties shall be entitled to an injunction or injunctions to prevent breaches of
the provisions of this Agreement and to enforce specifically the terms and
provisions hereof, this being in addition to any other remedy to which they may
be entitled at law or in equity.

                                      -24-

      Section 9.12. Successors. Except as otherwise expressly provided in this
Agreement, Permitted Transferees are entitled to all of the rights and subject
to all of the obligations of the Transferor hereunder from whom they received
their Shares regardless of whether the Agreement elsewhere so expressly
provides.

      Section 9.13. Computation of Time. In computing any period of time under
this Agreement, the day of the act, event or default from which the designated
period of time begins to run shall not be included. The last day of the period
so computed shall be included, unless it is a Saturday, Sunday or legal holiday,
in which event the period shall run until the end of the next day which is not a
Saturday, Sunday or legal holiday.

      Section 9.14. Additional Shares Subject to Agreement. Each Employee agrees
that any other Shares which it shall hereafter acquire by means of a stock
split, stock dividend, distribution, exercise of stock options, or otherwise
shall be subject to the provisions of this Agreement to the same extent as if
held on the date hereof.
