and binding upon all Persons (including the Company or any Subsidiary or
Affiliate thereof, any Participant, any holder or beneficiary of any Option, any
stockholder and any Employee).

        SECTION 4.    Shares Available for Options.    

        (a)    Shares Available. Subject to adjustment as provided in
Section 4(b), the number of Shares with respect to which Options may be granted
under the Plan shall be the sum of (i) 3,447,789, plus (ii) the amount by which
39,363 exceeds the total number of Shares purchased with Loans during the period
after the closing of the transactions contemplated by the Merger Agreement
through December 31, 2000. Super Performance Vesting Options may not be granted
to purchase Shares in excess of the number set forth in clause (ii) of the
preceding sentence, and Options other than Super Performance Vesting Options may
not be granted to purchase Shares in excess of the number set forth in
clause (i) of the preceding sentence. If, after the effective date of the Plan,
any Shares covered by an Option granted under the Plan (other than a Substitute
Option) or to which such an Option relates are forfeited, or if such an Option
otherwise terminates or is canceled without the delivery of Shares, then the
Shares covered by such Option, or to which such Option relates, or the number of
Shares otherwise counted against the aggregate number of Shares with respect to
which Options may be granted, to the extent of any such settlement, forfeiture,
termination or cancellation, shall again become Shares with respect to which
Options may be granted under clause (i) or (ii) above, depending on whether the
forfeited, terminated or canceled Option was a Super Performance Vesting Option.
Notwithstanding the foregoing and subject to adjustment as provided in
Section 4(b), no Participant may receive Options in any calendar year that
relate to more than 900,000 Shares (subject to adjustment as provided in
Section 4(b)).

        (b)    Adjustments. In the event that the Compensation Committee
determines that any dividend or other distribution (whether in the form of cash,
Shares, other securities or other property), recapitalization, stock split,
reverse stock split, reorganization, reclassification, merger, consolidation,
split-up, spin-off, combination, repurchase, or exchange of Shares or other
securities of the Company, issuance of warrants or other rights to purchase
Shares or other securities of the Company or other similar corporate transaction
or event affects the Shares such that an adjustment is determined by the
Compensation Committee to be appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan, then the Compensation Committee shall, in such manner as it may
deem equitable, adjust any or all of:

        (i)    the number of Shares of the Company (or number and kind of other
securities or property) with respect to which Options may thereafter be granted;

5

--------------------------------------------------------------------------------

        (ii)  the number of Shares or other securities of the Company (or number
and kind of other securities or property) subject to outstanding Options; and

        (iii)  the grant or exercise price with respect to any Option, or, if
deemed appropriate, make provision for a cash payment to the holder of an
outstanding Option.

        (c)  Substitute Options. Any Shares underlying Substitute Options shall
not be counted against the Shares available for Options under the Plan.

        (d)  Sources of Shares Deliverable Under Options. Any Shares delivered
pursuant to an Option may consist, in whole or in part, of authorized and
unissued Shares or of treasury Shares.

        SECTION 5.    Eligibility.    Any Employee, non-employee director of the
Company or any Subsidiary or Affiliate thereof or consultant to the Company or
any Subsidiary or Affiliate thereof shall be eligible to be designated a
Participant. Holders of options granted by a company that is acquired by the
Company or with which the Company combines are eligible for grants of Substitute
Options hereunder in connection with such acquisition or combination
transaction.

        SECTION 6.    Stock Options.    

        (a)  Grant. Subject to the provisions of the Plan and contractual
restrictions (including, to the extent applicable, any Award Agreements or
Employment Agreements) affecting the Company, the Compensation Committee shall
have sole and complete authority to determine the Participants to whom Options
shall be granted, the number of Shares to be covered by each Option, the
exercise price therefor and the conditions and limitations applicable to the
exercise of the Option.

        (b)  Exercise Price. The Compensation Committee shall, in its sole
discretion, establish the exercise price at the time each Option is granted.

        (c)  Exercise. Each Option shall be exercisable at such times and
subject to such terms and conditions as the Compensation Committee may, in its
sole discretion, specify in the applicable Award Agreement or thereafter. The
Compensation Committee may impose such conditions with respect to the exercise
of Options, including without limitation, any relating to the application of
federal or state securities laws, as it may deem necessary or advisable.

        (d)  Payment. No Shares shall be delivered pursuant to any exercise of
an Option until payment in full of the exercise price, or adequate provision
therefor, is received by the Company. Such payment may be made: (i) in cash;
(ii) in Shares owned by the Participant (the value of such Shares shall be their
Fair Market Value on the date of exercise); (iii) by a combination of cash and
Shares; (iv) if approved by the Compensation Committee, in accordance with a
cashless exercise program; or (v) in such other manner as permitted by the
Compensation Committee at the time of grant or thereafter.

        SECTION 7.    Vesting; Termination of Employment.    Each Award
Agreement shall contain such terms as the Compensation Committee may in its sole
discretion determine concerning vesting, forfeiture, the Company's rights of
repurchase of Shares acquired upon exercise of an Option, and/or the effects of
termination or suspension of a Participant's employment upon the exercisability
of any Option granted thereunder.

        SECTION 8.    Accelerated Vesting.    The Compensation Committee may, in
its sole discretion, provide in an Award Agreement or at any other time for the
accelerated vesting of an Option.

        SECTION 9.    Amendment and Termination.    

        (a)  Amendments to the Plan. The Board may amend, alter, suspend,
discontinue, or terminate the Plan or any portion thereof at any time; provided
that no such amendment, alteration, suspension, discontinuation or termination
shall be made without stockholder approval if such approval is necessary to
qualify for or comply with any tax or regulatory status or requirement
(including any approval

6

--------------------------------------------------------------------------------

requirement which is a prerequisite for exemptive relief from Section 16(b) of
the Exchange Act or Section 162(m) of the Code) for which or with which the
Board deems it necessary or desirable to qualify or comply; provided further,
that any such amendment, alteration, suspension, discontinuance or termination
that would adversely affect the rights of the Participant or any holder or
beneficiary of any Option theretofore granted shall not to the extent be
effective without the consent of such affected Participant, holder or
beneficiary. Notwithstanding anything to the contrary herein, the Compensation
Committee may amend the Plan in such manner as may be necessary so as to have
the Plan conform with local rules and regulations in any jurisdiction outside
the United States.

        (b)  Amendments to Options. Subject to the terms of the Plan, the
applicable Award Agreement and applicable law, the Compensation Committee may
waive any conditions or rights under, amend any terms of, or alter, suspend,
discontinue, cancel or terminate, any Option theretofore granted, prospectively
or retroactively; provided that any such waiver, amendment, alteration,
suspension, discontinuance, cancellation or termination that would adversely
affect the rights of a Participant or any holder or beneficiary of any Option
theretofore granted shall not to that extent be effective without the consent of
such affected Participant, holder or beneficiary.

        (c)  Cancellation. Any provision of this Plan or any Award Agreement to
the contrary notwithstanding, in the event of a Change of Control or an offer to
Participants generally relating to the acquisition of Shares, including through
purchase, merger or otherwise, the Compensation Committee may cause any Option
granted hereunder to be canceled and, in consideration of such canceled option,
pay the holder (i) a cash payment equal to the difference between the aggregate
value of the Shares (based upon the Change of Control or other acquisition
offer) subject to the Option and the aggregate exercise price of such Option
(the "Intrinsic Value") or (ii) a substitute option (preserving the Intrinsic
Value of the canceled Option).

        SECTION 10.    Treatment of Ungranted Options Upon Occurrence of a
Liquidity Event.    Immediately prior to the occurrence of a Liquidity Event (as
defined in Annex A hereto), the Board shall award Options, at an exercise price
of $10.00 per Share (as adjusted to reflect any of the events contemplated by
Section 4(b)), to purchase that portion of the Shares on which Options are
authorized to be granted under Section 4(a)(i) of the Plan as to which Options
have not, as of such date, previously been granted. For the avoidance of doubt,
Options which have been granted and subsequently canceled, forfeited, terminated
or repurchased shall be treated as having been previously granted, pursuant to
the preceding sentence. The Options granted under this Section 10 shall be
allocated among persons eligible for an award under Section 5 hereof, in the
sole discretion of the Board.

        SECTION 11.    General Provisions.    

        (a)  Dividend Equivalents. In the sole and complete discretion of the
Compensation Committee, an Option may provide the Participant with dividends or
dividend equivalents, payable in cash, Shares, other securities or other
property on a current or deferred basis.

        (b)  Non-Transferability of Options. Except to the extent otherwise
provided in a Participant's Award Agreement, no Option shall be assigned,
alienated, pledged, attached, sold or otherwise transferred or encumbered by
such Participant, except by will or the laws of descent and distribution.

        (c)  No Rights to Options. No Employee, Participant or other Person
shall have any claim to be granted any Option, and there is no obligation for
uniformity of treatment of Employees, Participants or holders or beneficiaries
of Options. The terms and conditions of Options need not be the same with
respect to each recipient.

        (d)  Stock Certificates. Certificates, if any, issued in respect of
Shares shall, unless the Compensation Committee otherwise determines, be
registered in the name of the Participant or his or her Permitted Transferees
and, so long as a Participant continues to be governed by any forfeiture

7

--------------------------------------------------------------------------------

provisions relating to the Shares, shall be deposited by such Participant or
Permitted Transferee, together with a stock power endorsed in blank, with the
Company. When such forfeiture conditions lapse, the Company shall deliver such
certificates to the Participant upon request. Such stock certificate shall carry
such appropriate legends, and such written instructions shall be given to the
Company's transfer agent, as may be deemed necessary or advisable by counsel to
the Company in order to comply with the requirements of (i) the Securities Act
of 1933, as amended, any state securities laws or any other applicable laws and
(ii) the Shareholders' Agreement. Subject to the provisions of the Shareholders'
Agreement, all certificates for Shares or other securities of the Company or any
Subsidiary delivered under the Plan pursuant to any Option or the exercise
thereof shall be subject to such stop transfer orders and other restrictions as
the Compensation Committee may deem advisable under the Plan or the rules,
regulations and other requirements of the SEC or any exchange or market upon
which such Shares or other securities of the Company are then listed and any
applicable laws or rules or regulations, and the Compensation Committee may
cause a legend or legends to be put on any such certificates to make appropriate
reference to such restrictions.

        (e)  Withholding. A Participant may be required to pay to the Company or
any Subsidiary, and the Company or any Subsidiary shall have the right and is
hereby authorized to withhold from any Option, from any payment due or transfer
made under any Option or under the Plan or from any compensation or other amount
owing to a Participant the amount (in cash, Shares, other securities, other
Options or other property) of any applicable withholding taxes in respect of an
Option, its exercise or any payment or transfer under an Option or under the
Plan, and to take such other action as may be necessary in the opinion of the
Company to satisfy all obligations for the payment of such taxes. The
Compensation Committee may provide for additional cash payments to holders of
Options to defray or offset any tax arising from any such grant, lapse, vesting
or exercise of any Option.

        (f)    Award Agreements. Each Option hereunder shall be evidenced by an
Award Agreement which shall be delivered to the Participant and shall specify
the terms and conditions of the Option and any rules applicable thereto.

        (g)  No Limit on Other Compensation Arrangements. This Plan is not
intended to be the exclusive authority for the grant of options, stock or
stock-based awards, and nothing contained in this Plan shall prevent the Company
or any Subsidiary or Affiliate thereof from adopting or continuing in effect
other compensation arrangements, which may, but need not, provide for the grant
of options, restricted stock, Shares and other types of awards provided for
hereunder (subject to stockholder approval if such approval is required by
applicable law). Any such arrangements may be either generally applicable or
applicable only in specific cases.

        (h)  No Right to Employment. The grant of an Option shall not be
construed as giving a Participant the right to be retained in the employment or
service of the Company or any Subsidiary or Affiliate thereof. Further, the
Company or any Subsidiary may at any time dismiss a Participant from employment
or service, free from any liability or any claim under the Plan, unless
otherwise expressly provided in the Plan or in any Award Agreement.

        (i)    Rights as a Stockholder. Subject to the provisions of the
applicable Option, no Participant or holder or beneficiary of any Option shall
have any rights as a stockholder with respect to any Shares to be issued under
the Plan until he or she has become the holder of such Shares.

        (j)    Governing Law. The validity, construction, and effect of the Plan
and any rules and regulations relating to the Plan and any Award Agreement shall
be determined in accordance with the laws of the State of Delaware.

        (k)  Severability. If any provision of the Plan or any Option is or
becomes or is deemed to be invalid, illegal, or unenforceable in any
jurisdiction or as to any Person or Option, or would disqualify the Plan or any
Option under any law deemed applicable by the Compensation Committee, such

8

--------------------------------------------------------------------------------

provision shall be construed or deemed amended to conform to the applicable
laws, or if it cannot be construed or deemed amended without, in the
determination of the Compensation Committee, materially altering the intent of
the Plan or the Option, such provision shall be stricken as to such
jurisdiction, Person or Option, and the remainder of the Plan and any such
Option shall remain in full force and effect.

        (l)    Other Laws. The Compensation Committee may refuse to issue or
transfer any Shares or other consideration under an Option if, acting in its
sole discretion, it determines that the issuance or transfer of such Shares or
such other consideration might violate any applicable law or regulation or
entitle the Company to recover the same under Section 16(b) of the Exchange Act,
and any payment tendered to the Company by a Participant in connection therewith
shall be promptly refunded to the relevant Participant, holder or beneficiary.
Without limiting the generality of the foregoing, no Option granted hereunder
shall be construed as an offer to sell securities of the Company, and no such
offer shall be outstanding, unless and until the Compensation Committee in its
sole discretion has determined that any such offer, if made, would be in
compliance with all applicable requirements of the federal and state securities
laws and any other laws to which such offer, if made, would be subject.

        (m)  No Trust or Fund Created. Neither the Plan nor any Option shall
create or be czonstrued to create a trust or separate fund of any kind or a
fiduciary relationship between the Company or any Subsidiary and a Participant
or any other Person. To the extent that any Person acquires a right to receive
payments from the Company or any Subsidiary or Affiliate thereof pursuant to an
Option, such right shall be no greater than the right of such unsecured general
creditor of the Company or such Subsidiary or Affiliate thereof.

        (n)  No Fractional Shares. No fractional Shares shall be issued or
delivered pursuant to the Plan or any Option, and the Compensation Committee
shall determine whether cash or other securities or other property shall be paid
or transferred in lieu of any fractional Shares or whether such fractional
Shares or any rights thereto shall be canceled, terminated or otherwise
eliminated.

        (o)  Shareholders' Agreement Transfer Restrictions. A Participant shall,
as a condition precedent to the exercise or settlement of an Option, execute an
instrument agreeing to be bound by the terms of the Shareholders' Agreement or,
at the election of the Company, a counterpart of the Shareholders' Agreement. In
any event, any Shares acquired upon exercise or settlement shall be subject to
the provisions in the Shareholders' Agreement regarding restrictions on transfer
and the Company's rights to compel sales and repurchase Shares.

        (p)  Headings. Headings are given to the sections and subsections of the
Plan solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
the Plan or any provision thereof.

        SECTION 12.    Term of the Plan.    

        (a)  Effective Date. The Plan shall be effective as of October 11, 2000
subject to approval by the stockholders of the Company. Options may be granted
hereunder prior to such stockholder approval, subject in all cases, however, to
such approval.

        (b)  Expiration Date. Unless otherwise expressly provided in the Plan or
in an applicable Award Agreement, any Option granted hereunder may, and the
authority of the Board or the Compensation Committee to amend, alter, adjust,
suspend, discontinue or terminate any such Option or to waive any conditions or
rights under any such Option shall, continue after the authority for grant of
new Options hereunder has been exhausted.

(the "Date of Grant"); provided that the Optionee is then, and at all times
since the Date of Grant has been, in the employment of (or, in the case of a
non-employee director of the Company or any Subsidiary or Affiliate thereof or a
consultant to the Company or any Subsidiary or Affiliate thereof, in the service
of) the Company or a Subsidiary or Affiliate thereof.

        2. Upon achievement of the respective EBITDA objectives set forth in
clause (a) of this Paragraph I. 2 in respect of the fiscal years ending
December 31, 2002, 2003 and 2004 (each such date, a "Year-End Date"), the Shares
subject to the Performance Vesting Option shall vest on March 31 following such
Year-End Date (each such date, a "Performance Vesting Date"), in accordance with
clause (a) of and, the provisions and procedures set forth in, this Paragraph I.
2; provided that the Optionee is, on such Performance Vesting Date, and at all
times since the Date of Grant has been, in the employment or service, as the
case may be, of the Company or a Subsidiary or Affiliate thereof. By action of
the Board on March 7, 2002, 25% of the Shares subject to the Performance Vesting
Option were vested on March 31, 2002.

        (a) Establishment of EBITDA Objectives and Corresponding Vesting. For
each of the fiscal years ending on December 31, 2002, 2003 and 2004, the Company
has established, subject to adjustment pursuant to Paragraph II, target amounts
(each, a "Target Amount") and floor amounts (each, a "Floor Amount") for EBITDA
(as defined herein) and corresponding vesting amounts for the Performance
Vesting Options set forth herein.

        (b) If EBITDA Is At Least Equal to Floor Amount But Less Than Target
Amount. If EBITDA of the Company and its Subsidiaries for a fiscal year is at
least equal to the Floor Amount for such fiscal year, but less than the Target
Amount for such fiscal year, then the Performance Vesting Option will vest and
become exercisable to purchase:

        (i) 20% of the Shares subject to the Performance Vesting Option; plus

        (ii) that number of additional Shares equal to the product of (x) 5% of
the Shares subject to the Performance Vesting Option and (y) a fraction, the
numerator of which shall be equal to the excess of EBITDA of the Company and its
Subsidiaries for such fiscal year over the Floor Amount for such fiscal year and
the denominator of which is equal to the excess of the Target Amount for such
fiscal year over the Floor Amount for such fiscal year.

        (c) If EBITDA Equals or Exceeds Target Amount. If EBITDA of the Company
and its Subsidiaries for a fiscal year is equal to or exceeds the Target Amount
for such fiscal year, then

--------------------------------------------------------------------------------

the Performance Vesting Option will vest and become exercisable to purchase 25%
of the Shares subject to the Performance Vesting Option.

        3. Notwithstanding anything to the contrary contained in Paragraph I. 2,
upon achievement by the Company of EBITDA of at least $131.3 million (the "2005
Target") in respect of the fiscal year ending December 31, 2005, all unvested
Shares subject to the Performance Vesting Option shall vest on March 31, 2006;
provided that the Optionee is on March 31, 2006, and at all times since the Date
of Grant has been, in the employment or service, as the case may be, of the
Company or a Subsidiary or Affiliate thereof.

        4. For purposes of this Annex A, "EBITDA" for a fiscal year shall have
the meaning assigned to it in the Credit Agreement and shall be subject to
adjustment as set forth in the immediately subsequent paragraph; provided that
EBITDA shall not include (i) Transaction Payments as defined in the Credit
Agreement and (ii) liability for or payment by the Company or its Subsidiaries
of annual retainer to Donaldson, Lufkin & Jenrette Securities Corporation (or
any affiliate or successor thereof).

II. ADJUSTMENT OF EBITDA TARGETS UPON ACQUISITIONS AND DISPOSITIONS.

        1. From time to time, the Board (or the Compensation Committee thereof)
may make adjustments in EBITDA for a fiscal year so that extraordinary or
unusual charges or credits, acquisitions, mergers, consolidations, dispositions
and other corporate transactions and other elements of or factors influencing
the calculation of EBITDA do not distort or affect the operation of the Plan in
a manner inconsistent with its purpose. The good faith decisions of the Board
(or, if applicable, the Compensation Committee thereof) as to the computation of
EBITDA and other good faith determinations to be made with respect to the Plan
shall be final, conclusive and binding on all parties.

        2. (a) Notwithstanding the foregoing, if the Company or its Subsidiaries
effectuate any acquisitions during a fiscal year, the Floor and Target Amounts
set forth in Paragraph I. 2(a) shall be adjusted, effective as of immediately
prior to the Performance Vesting Date for such year, by adding to each such
amount the product of (1) 90% and 100%, respectively, multiplied by (2) the
"Acquisition EBITDA," as defined below, resulting from each acquisition
completed during such fiscal year. For this purpose, the "Acquisition EBITDA"
resulting from any acquisition shall mean the estimated pro forma EBITDA for the
period of the current year after the acquisition and each remaining full year
among the four fiscal years set forth above.

        (b) Notwithstanding the foregoing, if the Company or its Subsidiaries
effectuate any acquisitions prior to December 31, 2005, the 2005 Target shall be
adjusted by adding to such amount the pro forma EBITDA which is forecast at the
time of acquisition to be generated in fiscal year 2005 by each such acquired
property.

        3. (a) Notwithstanding the foregoing, if the Company or its Subsidiaries
effectuate any disposition during a fiscal year, and if the Disposition
Contribution, as defined below, for such disposition is positive, the Floor and
Target Amounts set forth in Paragraph I. 2(a) for the fiscal year in which such
disposition occurs and all subsequent fiscal years shall be adjusted, effective
as of immediately prior to the Performance Vesting Date for such year, by
multiplying such Floor and Target amounts by the "Disposition Fraction", as
defined below, for such disposition. For this purpose, the "Disposition
Fraction" for any disposition shall mean a fraction determined by subtracting
from 1 a fraction the numerator of which shall be the Contribution generated by
the business disposed of for the fiscal year most recently completed prior to
such disposition (the "Disposition Contribution" for such disposition), and the
denominator of which shall be the total Contribution of the Company and its
Subsidiaries for the fiscal year most recently completed prior to such
disposition. For the avoidance of doubt, in the event that the Disposition
Contribution is a negative number, the Disposition Fraction shall be deemed to
be 1, and no adjustment shall be made to the Floor and Target Amounts.

--------------------------------------------------------------------------------

        (b) Notwithstanding the foregoing, if the Company or its Subsidiaries
effectuate any dispositions prior to December 31, 2005, the 2005 Target shall be
adjusted by subtracting from such amount the pro forma EBITDA for fiscal year
2005 which is included in the current bank plan (March 2002) to be generated by
each such disposed property.

        4. Upon the occurrence of a Change of Control which is a Liquidity
Event, the Performance Vesting Option shall vest in its entirety and become
immediately exercisable. A "Liquidity Event" means any event in connection with
which the DLJ Funds realize cash in respect of their investment in shares of
capital stock of the Company, including without limitation a sale, partial sale,
liquidation, partial liquidation or dividend; provided that (i) if such
realization occurs on or prior to the third anniversary of the Effective Time,
as defined in the Merger Agreement (the "Effective Time"), such amount of cash,
added to all cash previously received by the DLJ Funds in connection with their
aggregate capital investment (the "DLJ Capital Investment"), equals or exceeds
on a cumulative basis 200% of the DLJ Capital Investment; (ii) if such
realization occurs after the third anniversary of the Effective Time but prior
to the fourth anniversary of the Effective Time, such amount of cash, added to
all cash previously received by the DLJ Funds in connection with their
investment, equals or exceeds 300% of the DLJ Capital Investment; and (iii) if
such realization occurs on or after the fourth anniversary of the Effective
Time, such amount of cash equals or exceeds 400% of the DLJ Capital Investment.

        5. Upon a Change of Control, if such Change of Control constitutes a
Liquidity Event, the Performance Vesting Option shall vest in its entirety and
become immediately exercisable.
