as follows:

                                    AGREEMENT

         1.       Definitions. Capitalized terms used herein but not otherwise
defined herein shall have the following meanings:

                  "Act" means the Securities Act of 1933, as amended.

                  "Cause" means that the Employee (a) has been convicted of a
         felony, or has entered a plea of guilty or nolo contendere to a felony;
         (b) has committed an act of fraud or dishonesty which is materially
         injurious to the Company or any of its Subsidiaries; (c) has willfully
         and continually refused to perform his or her duties with the Company
         or any of its Subsidiaries; or (d) has engaged in gross misconduct that

                  "Good Reason" means (a) the assignment to the Employee of
         duties, or the assignment of the Employee to a position, constituting a
         material diminution in the Employee's role, responsibilities or

         with the Company or its affiliates on the date hereof; (b) a reduction
         by the Company in the Employee's base salary as in effect from time to
         time; or (c) a demand by the Company to the Employee to relocate to any

         however, that in the event that any change in the Employee's duties,
         position, role, responsibilities or authority is implemented or
         proposed to be implemented by the Company during the term of his or her
         employment with the Company, then: (i) unless the Employee provides
         written notice to the Company and the Chief Executive Officer of the
         Company within 30 days of being notified of such

<PAGE>

         change or proposed change that the Employee asserts that such change
         constitutes a "material diminution", such change shall be deemed not to
         be such a "material diminution" and thereafter the Employee's duties,
         position, role, responsibilities and authority shall be as so changed;
         and (ii) in the event that the Employee provides such notice in a
         timely manner and, within 30 days thereafter, the Company, in its sole
         discretion, rescinds or alters such change, then the original change
         shall be disregarded (except to the extent so altered).

         stock of the Company pursuant to a registration statement that has been

         attributable to the outstanding stock of the Company), whether pursuant
         to the sale of the stock of the Company, the sale of the assets of the
         Company, or a merger or consolidation (other than a sale of stock by a

         2.       Cash Bonus Amount. For each fiscal year of the Company set
forth on Exhibit A attached hereto and subject to the conditions set forth in

Exhibit A with respect to such fiscal year. If for any fiscal year set forth on
Exhibit A the Company's annual EBITDA amount for that fiscal year equals or
exceeds 95% of the Target Annual EBITDA amount set forth in column (A) with
respect to such fiscal year, but is less than 100% of such Target Annual EBITDA
amount, then, subject to the conditions set forth in Section 3 hereof, the
Employee shall accrue the right to 75% of the Cash Bonus Amount that the
Employee would have accrued had the Company achieved 100% of its Target Annual
EBITDA amount for that fiscal year. If for any fiscal year set forth on Exhibit

<PAGE>

EBITDA amount set forth in column (A) with respect to such fiscal year, but is
less than 95% of such Target Annual EBITDA amount, then, subject to the
conditions set forth in Section 3 hereof, the Employee shall accrue the right to
50% of the Cash Bonus Amount that the Employee would have accrued had the

If for any fiscal year set forth on Exhibit A the Company's cumulative annual
EBITDA amount for that and the proceeding fiscal years equals or exceeds the
Cumulative Target EBITDA amount set forth in column (B) of Exhibit A with
respect to such fiscal year, and subject to the conditions set forth in Section
3 hereof, the Employee shall accrue the right to the Cash Bonus Amount as if the
Company had achieved its Target Annual EBITDA amounts for that and each of the
preceding fiscal years.

         3.       Payment of Cash Bonus Amount. (a) Upon the consummation of a
Liquidity Event or an Initial Public Offering and subject to Section 4 hereof,
the Company shall pay, or cause to be paid, to the Employee, subject to Section
6 hereof, the aggregate amount of the accrued Cash Bonus Amount.

                  (b)      If the Employee is terminated without Cause
(including, but not limited to disability or death) or resigns with Good Reason
after the date hereof but prior to the earlier of (i) December 31, 2008, or (ii)
a Liquidity Event or an Initial Public Offering, then upon the consummation of a
Liquidity Event or an Initial Public Offering the Company shall pay, or cause to
be paid, to the Employee the aggregate Cash Bonus Amount that such Employee had
accrued as of the date such Employee ceased to be so employed.

Employee's employment with the Company terminates for any reason.

                  (b)      The Employee shall not be considered to have ceased
to be employed by the Company for purposes of this Agreement if he or she
continues to be employed by the Company or a Subsidiary, or by a company of
which the Company is a Subsidiary.

         5.       Not an Employment Contract. This Agreement shall not confer
upon the Employee any right with respect to continuance of employment with the
Company or any affiliate of the Company, nor shall it interfere in any way with
the right of the Company to terminate the Employee's employment at any time.

         6.       Taxes. Any payment made hereunder shall be subject to
withholding of such taxes as the Company shall deem appropriate.

         7.       Notices. All notices and other communications given or made

         Earnings Before Interest, Taxes, Depreciation and Amortization
("EBITDA") for a particular period is defined as Consolidated Net Income (loss)
of the Company and its subsidiaries as shown on the consolidated statement of
income (loss) for such period prepared in accordance with U.S. GAAP,
consistently applied, which shall (a) exclude or be adjusted otherwise for all
acquisitions and additional equity contributions to the extent such acquisitions
and/or equity contributions materially change target EBITDA for any particular
fiscal year of the Company, (b) reflect a reduction for all management and
employment bonuses payable with respect to the fiscal year of the Company and
(c) be adjusted for any material amendment to the capital expenditure plan
approved by the Board of Directors of the Company (the "Board"); plus (minus),
to the extent such amounts are otherwise taken into account in determining
EBITDA (prior to adjustment), the following:

                  1.       Any provision (benefit) for taxes, including
         franchise taxes, deducted (added) in calculating such consolidated net
         income (loss);

                  2.       Any interest expense (net of interest income),
         deducted in calculating such consolidated net income (loss);

                  3.       Amortization expenses deducted in calculating such
         consolidated net income (loss);

                  4.       Depreciation expense deducted in calculating
         consolidated net income (loss);

                  5.       Management fees paid to Investcorp to the extent
         recorded as an expense in calculating such consolidated net income
         (loss);

                  6.       Any unusual losses (gains) deducted (added) in
         calculating such consolidated net income (loss). This adjustment is
         intended to exclude, in the calculation of EBITDA, the effects, if any,
         of any transactions outside of the Company's ordinary

                                       A-1
<PAGE>

         course of business as and to the extent determined to be appropriate in
         good faith by the Board.

         The Board reserves the right to make other adjustments to EBITDA or the
EBITDA targets as the Board determines in good faith are appropriate to take
into account the effect of material transactions or events during the period,
including without limitation acquisitions, divestitures, equity issuances and
significant changes to capital expenditure plans.

         The Employee and his or her representative shall be provided reasonable
opportunity to review the computation of EBITDA and reasonable access to the
data and information supporting such computation, but the Board's determination
shall be conclusive and binding.

         or the Indenture, the absence of any action to enforce the same, any
         waiver or consent by any Holder of the Notes with respect to any
         provisions hereof or thereof, the recovery of any judgment against the
         Company, any action to enforce the same or any other circumstance which
         might otherwise constitute a legal or equitable discharge or defense of
         a guarantor.

                  (c) The following is hereby waived: diligence, presentment,
         demand of payment, filing of claims with a court in the event of
         insolvency or bankruptcy of the Company, any right to require a
         proceeding first against the Company, protest, notice and all demands
         whatsoever.

                  (d) This Guarantee shall not be discharged except by complete
         performance of the Obligations contained in the Notes and the Indenture
         or pursuant to Section 6 hereof.

                  (e) If any Holder or the Trustee is required by any court or
         otherwise to return to the Company, the Guarantors, or any custodian,
         Trustee, liquidator or other similar official acting in relation to
         either the Company or the Guarantors, any amount paid by

                                       2
<PAGE>

         either to the Trustee or such Holder, this Guarantee, to the extent
         theretofore discharged, shall be reinstated in full force and effect.

                  (f) Each Guaranteeing Subsidiary shall not be entitled to any
         right of subrogation in relation to the Holders in respect of any
         Obligations guaranteed hereby until payment in full of all Obligations
         guaranteed hereby.

                  (g) As between the Guarantors, on the one hand, and the
         Holders and the Trustee, on the other hand, (x) the maturity of the
         Obligations guaranteed hereby may be accelerated as provided in Article
         6 of the Indenture for the purposes of this Guarantee, notwithstanding
         any stay, injunction or other prohibition preventing such acceleration
         in respect of the Obligations guaranteed hereby, and (y) in the event
         of any declaration of acceleration of such Obligations as provided in
         Article 6 of the Indenture, such Obligations (whether or not due and
         payable) shall forthwith become due and payable by the Guarantors for
         the purpose of this Guarantee.

                  (h) The Guarantors shall have the right to seek contribution
         from any non-paying Guarantor so long as the exercise of such right
         does not impair the rights of the Holders under the Guarantee.

                  (i) Pursuant to Section 11.03 of the Indenture, the
         Obligations of a Guaranteeing Subsidiary shall be limited to such a
         maximum amount as after giving effect to any maximum amount and any
         other contingent and fixed liabilities that are relevant under any
         applicable Bankruptcy or fraudulent conveyance laws (including, without
         limitation, all Senior Debt of such Guarantor), and after giving effect
         to any collections from, rights to receive contribution from or
         payments made by or on behalf of any other Guarantor in respect of the
         Obligations of such other Guarantor under Article 11 of the Indenture,
         shall result in the Obligations of such Guarantor under its Guarantee
         not constituting a fraudulent transfer or conveyance.

         3. SUBORDINATION. The Obligations of each Guaranteeing Subsidiary under
its Guarantee pursuant to this Supplemental Indenture shall be junior and
subordinated to the Senior Debt of each Guaranteeing Subsidiary on the same
basis as the Notes are junior and subordinated to the Senior Debt of the
Company. For the purposes of the foregoing sentence, the Trustee and the Holders
shall have the right to receive and/or retain payments by each Guaranteeing
Subsidiary only at such time as they may receive and/or retain payments in
respect of the Notes pursuant to the Indenture, including Article 10 thereof.

         4. EXECUTION AND DELIVERY. Each Guaranteeing Subsidiary agrees that the
Guarantees shall remain in full force and effect notwithstanding any failure to
endorse on each Note a notation of such Guarantee.

         5. GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.

                  (a) Each Guaranteeing Subsidiary may not consolidate with or
         merge with or into (whether or not such Guarantor is the surviving
         Person) another corporation, Person or entity whether or not affiliated
         with such Guarantor unless:

                                       3
<PAGE>

                           (i) subject to Section 11.05 of the Indenture, the
         Person formed by or surviving any such consolidation or merger (if
         other than a Guarantor or the Company) shall be a corporation organized
         and validly existing under the laws of the United States or any state
         thereof or the District of Columbia, and unconditionally assumes all
         the Obligations of such Guarantor, pursuant to a supplemental indenture
         in form and substance reasonably satisfactory to the Trustee, under the
         Notes, the Indenture and the Guarantee on the terms set forth herein or
         therein;

                           (ii) immediately after giving effect to such
         transaction, no Default or Event of Default exists; and

                           (iii) the Company would be permitted, immediately
         after giving effect to such transaction, to incur at least $1.00 of
         additional Indebtedness (other than Permitted Indebtedness) pursuant to
         Section 4.09 of the Indenture.

                  (b) In case of any such consolidation, merger, sale or
         conveyance and upon the assumption by the successor Person, by
         supplemental indenture, executed and delivered to the Trustee and
         satisfactory in form to the Trustee, of the Guarantee endorsed upon the
         Notes and the due and punctual performance of all of the covenants and
         conditions of the Indenture to be performed by the Guarantor, such
         successor Person shall succeed to and be substituted for the Guarantor
         with the same effect as if it had been named herein as a Guarantor.
         Such successor Person thereupon may cause to be signed any or all of
         the Guarantees to be endorsed upon all of the Notes issuable hereunder
         which theretofore shall not have been signed by the Company and
         delivered to the Trustee. All the Guarantees so issued shall in all
         respects have the same legal rank and benefit under the Indenture as
         the Guarantees theretofore and thereafter issued in accordance with the
         terms of the Indenture as though all of such Guarantees had been issued
         at the date of the execution hereof.

                  (c) Except as set forth in Articles 4 and 5 of the Indenture,
         and notwithstanding clause (a) (iii) above, nothing contained in the
         Indenture or in any of the Notes shall prevent any consolidation or
         merger of a Guarantor with or into the Company or another Guarantor, or
         shall prevent any sale or conveyance of the property of a Guarantor as
         an entirety or substantially as an entirety to the Company or another
         Guarantor.

         6. RELEASES. In the event of a sale or other disposition of all of the
assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale
or other disposition of all to the capital stock of any Guarantor, then such
Guarantor (in the event of a sale or other disposition, by way of merger,
consolidation or otherwise, of all of the capital stock of such Guarantor) or
the corporation acquiring the property (in the event of a sale or other
disposition of all or substantially all of the assets of such Guarantor) will be
released and relieved of any Obligations under its Guarantee; provided that the
Net Cash Proceeds of such sale or other disposition are applied in accordance
with the applicable provisions of the Indenture, including without limitation
Section 4.10 of the Indenture. Upon delivery by the Company to the Trustee of an
Officers' Certificate and an Opinion of Counsel to the effect that such sale or
other disposition was made by the Company in accordance with the applicable
provisions of the Indenture, including without limitation Section 4.10 of the
Indenture, the Trustee shall execute

                                       4
<PAGE>

any documents reasonably required in order to evidence the release of any
Guarantor from its Obligations under its Guarantee.

         Any Guarantor not released from its Obligations under its Guarantee
shall remain liable for the full amount of principal of and interest on the
Notes and for the other Obligations of any Guarantor under the Indenture as
provided in Article 11 of the Indenture.

         7. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder or agent of each Guaranteeing
Subsidiary, as such, shall have any liability for any Obligations of the Company
or any Guaranteeing Subsidiary under the Notes, any Guarantees, the Indenture or
this Supplemental Indenture or for any claim based on, in respect of, or by
reason of, such Obligations or their creation. Each Holder of the Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes. Such waiver may not be
effective to waive liabilities under the federal securities laws and it is the
view of the Commission that such a waiver is against public policy.

         8. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT GIVING
EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE
APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

         9. COUNTERPARTS. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

         10. EFFECT OF HEADINGS. The Section headings herein are for convenience
only and shall not affect the construction hereof.

         11. THE TRUSTEE. The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which
recitals are made solely by each Guaranteeing Subsidiary and the Company.

                                       5

         IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed and attested, all as of the date first above
written.
