(b) With respect to each right to payment or performance included in the Collateral from time to time, the Transaction Lien granted therein includes a continuing security interest in (i) any Supporting Obligation that supports such payment or performance and (ii) any Lien that (x) secures such right to payment or performance or (y) secures any such Supporting Obligation.

(c) The Transaction Liens are granted as security only and shall not subject the Collateral Agent or any other Secured Party to, or transfer or in any way affect or modify, any obligation or liability of any Lien Grantor with respect to any of the Collateral or any transaction in connection therewith.

SECTION 3. General Representations and Warranties. Each Original Lien Grantor represents and warrants that:

(a) Such Lien Grantor is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization.

(b) Schedule 1 hereto lists, as of the Issue Date, (i) all Pledged Securities owned by such Lien Grantor and (ii) all Securities Accounts to which Financial Assets are credited in respect of which such Lien Grantor owns Security Entitlements. Such Lien Grantor owns no Commodity Account in respect of which such Lien Grantor is the Commodity Customer.

(c) Such Lien Grantor has, subject to Permitted Liens, good and marketable title to all its Collateral (subject to exceptions that are, in the aggregate, not material), free and clear of any Lien other than Permitted Liens.

(d) Such Lien Grantor has not performed any acts that would prevent the Collateral Agent from enforcing any of the provisions of the Security Documents or that would limit the Collateral Agent in any such enforcement. No financing statement, security agreement, mortgage or similar or equivalent document or instrument covering all or part of the Collateral owned by such Lien Grantor is on file or of record in any jurisdiction in which such filing or recording would be effective to perfect or record a

Lien on such Collateral, except financing statements, mortgages or other similar or equivalent documents with respect to (i) Permitted Liens and (ii) Liens of lenders under the Company's credit facilities that are being terminated as of the Issue Date. After the Issue Date, no Collateral owned by such Lien Grantor will be in the possession or under the Control of any other Person having a claim thereto or security interest therein, other than a holder of a Permitted Lien.

(e) The Transaction Liens on all Personal Property Collateral owned by such Lien Grantor (i) have been validly created, (ii) will attach to each item of such Collateral on the Issue Date (or, if such Lien Grantor first obtains rights thereto on a later date, on such later date) and (iii) when so attached, will secure all the Secured Obligations of such Lien Grantor.

(f) Such Lien Grantor has delivered a Perfection Certificate to the Collateral Agent. The information set forth therein is correct and complete in all material respects as of the Issue Date with respect to the Original Lien Grantors.

(g) When UCC financing statements describing the Collateral as set forth in such Lien Grantor's Perfection Certificate have been filed in the offices specified in such Perfection Certificate, the Transaction Liens will constitute perfected security interests in the Personal Property Collateral owned by such Lien Grantor to the extent that a security interest therein may be perfected by filing pursuant to the UCC, prior to all Liens and rights of others therein except Permitted Liens. When, in addition to the filing of such UCC financing statements, the applicable Intellectual Property Filings have been made with respect to such Lien Grantor's Recordable Intellectual Property (including any future filings required pursuant to Section 4(a) and 7(a)), the Transaction Liens will constitute perfected security interests in all right, title and interest of such Lien Grantor in its Recordable Intellectual Property to the extent that security interests therein may be perfected by such filings, prior to all Liens and rights of others therein except Permitted Liens. Except for (i) the filing of such UCC financing statements, (ii) such Intellectual Property Filings (including any future filings required pursuant to Sections 4(a) and 7(a)), (iii) filings required to record or perfect Liens on any Collateral subject to certificate title statutes and (vi) the due recordation of the Mortgages, no registration, recordation or filing with any governmental body, agency or official is required in connection with the execution or delivery of the Security Documents or is necessary for the validity or enforceability thereof or for the perfection or due recordation of the Transaction Liens or for the enforcement of the Transaction Liens.

(h) Such Lien Grantor has taken, and will continue to take, all actions necessary under the UCC to perfect its interest in any Accounts or Chattel Paper purchased or otherwise acquired by it, as against its assignors and creditors of its assignors.

(i) Such Lien Grantor's Collateral is insured as required by Section 4.05(b) ("Maintenance of Properties and Insurance") of the Indenture.

SECTION 4. Further Assurances; General Covenants. Each Lien Grantor covenants as follows:

(a) Such Lien Grantor will, from time to time, at the Company's expense, execute, deliver, file and record any statement, assignment, instrument, document, agreement or other paper and take any other action (including any Intellectual Property Filing and any filing of financing or continuation statements under the UCC) that from time to time may be necessary, or that the Collateral Agent may reasonably request, in order to:

(i) create, preserve, perfect, confirm or validate the Transaction Liens on such Lien Grantor's Collateral;

(ii) in the case of Pledged Deposit Accounts and Pledged Investment Property, cause the Collateral Agent to have Control thereof;

(iii) enable the Collateral Agent and the other Secured Parties to obtain the full benefits of the Security Documents; or

(iv) enable the Collateral Agent to exercise and enforce any of its rights, powers and remedies with respect to any of such Lien Grantor's Collateral.

Each Lien Grantor hereby authorizes the filing of any financing statements or continuation statements, and amendments to financing statements, in any jurisdictions and with any filing offices as are necessary or that the Collateral Agent may determine, in its sole discretion, are advisable to perfect the security interests granted to the Collateral Agent in connection herewith. Such financing statements may describe the collateral in the same manner as described in this Agreement or may contain an indication or description of collateral that describes such property in any other manner as is necessary or that the Collateral Agent may determine, in its sole discretion, is prudent to ensure the perfection of the security interest in the collateral granted to the Collateral Agent in connection herewith, including describing such property as "all assets whether now owned or hereafter acquired" or "all personal property whether now owned or hereafter acquired". Such Lien Grantor constitutes the Collateral Agent as its attorney-in-fact to execute and file all Intellectual Property Filings and other filings required or so requested for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; and such power, being coupled with an interest, shall be irrevocable until all the Transaction Liens granted by such Lien Grantor terminate pursuant to Section 21. The Lien Grantors, jointly and severally, agree to pay the costs of, or incidental to, any Intellectual Property Filings and any recording or filing of any financing or continuation statements or other documents recorded or filed pursuant hereto.

(b) Such Lien Grantor will not (i) change its name or corporate structure or (ii) change its location (determined as provided in UCC Section 9-307), unless it shall, within 30 days following any such change, file or record such financing statements, amendments thereto or other instruments or documents or take such other action as may be necessary to maintain the validity, perfection and priority of the Transaction Liens and provide the Collateral Agent with evidence of such filing, recordation or action having been taken.

(c) If any of its Collateral is in the possession or control of a warehouseman, bailee or agent at any time, such Lien Grantor will (i) notify such warehouseman, bailee or agent of the relevant Transaction Liens, (ii) instruct such warehouseman, bailee or agent to hold all such Collateral for the Collateral Agent's account subject to the Collateral Agent's instructions (which shall permit such Collateral to be removed by such Lien Grantor in the ordinary course of business until the Collateral Agent notifies such warehouseman, bailee or agent that an Event of Default has occurred and is continuing), (iii) cause such warehouseman, bailee or agent to Authenticate a Record acknowledging that it holds possession of such Collateral for the Collateral Agent's benefit and (iv) make such Authenticated Record available to the Collateral Agent; provided, that this Section 4(c) shall not apply to (A) the transfer of Collateral to third parties in connection with sales on consignment so long as the sale of such Collateral is otherwise described in clause (e) to the proviso to clause (2) of the definition of the term "Asset Sale" or (B) Collateral having an aggregate fair market value not exceeding $100,000.

(d) Such Lien Grantor will not sell, lease, exchange, assign or otherwise dispose of, or grant any option with respect to, any of its Collateral; provided that such Lien Grantor may do any of the foregoing unless (i) doing so would violate a covenant in the Indenture or (ii) an Event of Default shall have occurred and be continuing and the Collateral Agent shall have notified such Lien Grantor that its right to do so is terminated, suspended or otherwise limited. Concurrently with any sale, lease or other disposition (except a sale or disposition to another Lien Grantor or a lease) permitted by the foregoing proviso, the Transaction Liens on the assets sold or disposed of (but not in any Proceeds

arising from such sale or disposition) will cease immediately without any action by the Collateral Agent or any other Secured Party.

(a) Such Lien Grantor will use commercially reasonable efforts to cause to be collected from its account debtors, when due, all amounts owing under its Accounts (including delinquent Accounts with respect to which collection will be pursued in accordance with lawful collection procedures) and will apply all amounts collected thereon, forthwith upon receipt thereof, to the outstanding balances of such Accounts. Subject to the rights of the Collateral Agent and the other Secured Parties hereunder if an Event of Default shall have occurred and be continuing, such Lien Grantor may allow in the ordinary course of business as adjustments to amounts owing under its Accounts (i) any extension or renewal of the time or times for payment, or settlement for less than the total unpaid balance, that such Lien Grantor finds appropriate in accordance with sound business judgment and (ii) refunds or credits, all in the ordinary course of business and consistent with such Lien Grantor's historical collection practices. The costs and expenses (including attorney's fees) of collection, whether incurred by such Lien Grantor or the Collateral Agent, shall be paid by such Lien Grantor.

(b) If payments with respect to any of such Lien Grantor's Accounts are received in a lockbox or similar account, such Lien Grantor will (i) (A) at all times cause such account to be a Controlled Deposit Account and (B) cause the relevant Depositary Bank to subordinate to the relevant Transaction Lien all its claims to such account (except its right to deduct and setoff from such Controlled Deposit Account its normal operating charges, the amount of any overdrafts and uncollected funds previously credited, in each case, in respect of any Deposit Account of any Lien Grantor that is maintained with such Depositary Bank) or (ii) cause funds credited thereto to be swept therefrom to the extent necessary to comply with Section 9(d) (provided, however, that the applicable Lien Grantor shall not be required to sweep funds from the ATS Lockbox Account to a Controlled Deposit Account more frequently than twice per week). The Collateral Agent will instruct the relevant Depositary Bank to transfer funds credited to any such account, as promptly as practicable after receipt thereof, to a Controlled Deposit Account designated by such Lien Grantor; provided that, if an Event of Default shall have occurred and be continuing, the Collateral Agent may designate the Controlled Deposit Account to which such funds are transferred.

(c) If an Event of Default shall have occurred and be continuing, such Lien Grantor will, if requested to do so by the Collateral Agent, promptly notify (and such Lien Grantor authorizes the Collateral Agent so to notify) each account debtor in respect of any of its Accounts that such Accounts

have been assigned to the Collateral Agent hereunder, and that any payments due or to become due in respect of such Accounts are to be made directly to the Collateral Agent or its designee

(d) No Lien Grantor shall deposit, or direct any other Person to deposit, any funds or other amounts into the ATS Lockbox Account other than payments received from, or made by, customers in respect of services provided by the ATS Business.

Within 30 days after each March 31, June 30, September 30 and December 31 thereafter, it will sign and deliver to the Collateral Agent an appropriate Intellectual Property Security Agreement covering any Recordable Intellectual Property owned by it on such March 31, June 30, September 30 or December 31 that is not covered by any previous Intellectual Property Security Agreement so signed and delivered by it.

(b) Such Lien Grantor will notify the Collateral Agent promptly if it knows that any application or registration relating to any Recordable Intellectual Property owned or licensed by it may become abandoned or dedicated to the public, or of any adverse determination or development (including the institution of, or any adverse determination or development in, any proceeding in the United States Copyright Office, the United States Patent and Trademark Office or any court) regarding such Lien Grantor's ownership of such Recordable Intellectual Property, its right to register or patent the same, or its right to keep and maintain the same. If any of such Lien Grantor's rights to any Recordable Intellectual Property are infringed, misappropriated or diluted by a third party, such Lien Grantor will notify the Collateral Agent within 30 days after it learns thereof and will, unless such Lien Grantor shall reasonably determine that such action would be of negligible value, economic or otherwise, promptly xxx for infringement, misappropriation or dilution and to recover any and all damages for such infringement, misappropriation or dilution, and take such other actions as such Lien Grantor shall reasonably deem appropriate under the circumstances to protect such Recordable Intellectual Property.

For all purposes of the Security Documents or at such times as the Intercreditor Agreement may be in effect, the Intercreditor Agreement, including determining the amounts of the Secured Obligations or whether any action has been taken under any Secured Agreement, the Collateral Agent will be entitled to rely on information from (i) its own records for information as to the Secured Parties, their Secured Obligations and actions taken by them, (ii) any Secured Party for information as to its Secured Obligations and actions taken by it, to the extent that the Collateral Agent has not obtained such information from its own records, and (iii) the Company, to the extent that the Collateral Agent has not obtained information from the foregoing sources.

(d) Refusal to Act. The Collateral Agent may refuse to act on any notice, consent, direction or instruction from any Secured Parties or any agent, trustee or similar representative thereof that, in the Collateral Agent's opinion, (i) is contrary to law or the provisions of any Security Document or at such times as the Intercreditor Agreement may be in effect, the Intercreditor Agreement or (ii) may expose the Collateral Agent to liability (unless the Collateral Agent shall have been indemnified, to its reasonable satisfaction, for such liability by the Secured Parties that gave such notice, consent, direction or instruction).

SECTION 21. Termination Of Transaction Liens; Release Of Lien Grantors and Collateral. (a) The Transaction Liens granted by each Lien Grantor shall terminate as provided in Section 12.06 ("Release upon Satisfaction or Defeasance of all Outstanding Obligations") of the Indenture.

(b) At any time before the Transaction Liens granted by the Lien Grantors terminate, the Collateral Agent (i) shall release any Lien Grantor as provided in the last sentence of Section 5.02 ("Successor Corporation Substituted") or Section 10.02 ("Release of a Guarantor") of the Indenture or any Collateral as provided in Section 12.05 ("Specified Releases of Collateral") of the Indenture or if the Intercreditor Agreement is in effect, Section 5.1 ("Releases") of the Intercreditor Agreement or (ii) may, at the written request of the Company, release any Lien Grantor or any Collateral with the prior written consent of such Holders as are required to consent thereto under Section 9.02 ("With Consent of Holders") of the Indenture.

SECTION 22. Additional Lien Grantors. Any Guarantor may become a party hereto by signing and delivering to the Collateral Agent a Security Agreement Supplement, whereupon such Guarantor shall become a "Lien Grantor" as defined herein.

SECTION 23. Notices.

SECTION 24. No Implied Waivers; Remedies Not Exclusive. No failure by the Collateral Agent or any Secured Party to exercise, and no delay in exercising and no course of dealing with respect to, any right or remedy under any Security Document or at such times as the Intercreditor Agreement may be in effect, the Intercreditor Agreement shall operate as a waiver thereof; nor shall any single or partial exercise by the Collateral Agent or any Secured Party of any right or remedy under any Indenture Document preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies specified in the Indenture Documents are cumulative and are not exclusive of any other rights or remedies provided by law.

SECTION 25. Successors and Assigns. This Agreement is for the benefit of the Collateral Agent, the other Secured Parties and their respective successors and assigns.

SECTION 26. Amendments and Waivers. Neither this Agreement nor any provision hereof may be waived, amended, modified or terminated except pursuant to an agreement or agreements in writing entered into by the Collateral Agent pursuant to Article Nine ("Amendments, Supplements and Waivers") of the Indenture. No such waiver, amendment or modification shall (i) be binding upon any Lien Grantor, except with its written consent, or (ii) affect the rights of a Secured Party (other than a Holder) hereunder more adversely than it affects the comparable rights of the Holders hereunder, without the consent of such Secured Party.

SECTION 27. Choice of Law. This Agreement shall be construed in accordance with and governed by the laws of the State of New York, except as otherwise required by mandatory provisions of law and except to the extent that remedies provided by the laws of any jurisdiction other than the State of New York are governed by the laws of such jurisdiction.

SECTION 28. Waiver of Jury Trial. EACH PARTY HERETO WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO ANY SECURITY DOCUMENT OR AT SUCH TIMES AS THE INTERCREDITOR AGREEMENT MAY BE IN EFFECT, THE INTERCREDITOR AGREEMENT OR ANY TRANSACTION CONTEMPLATED THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 29. Severability. If any provision of any Security Document or at such times as the Intercreditor Agreement may be in effect, the Intercreditor Agreement is invalid or unenforceable in any jurisdiction, then, to the fullest extent permitted by law, (i) the other provisions of the Security Documents and at such times as the Intercreditor Agreement may be in effect, the Intercreditor Agreement shall remain in full force and effect in such jurisdiction and shall be liberally construed in

favor of the Collateral Agent and the Secured Parties in order to carry out the intentions of the parties thereto as nearly as may be possible and (ii) the invalidity or unenforceability of such provision in such jurisdiction shall not affect the validity or enforceability thereof in any other jurisdiction.

SECTION 30. Counterparts. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of any executed counterpart of a signature page of this Agreement by facsimile shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 31. Intercreditor Agreement. At any time that the Intercreditor Agreement shall be in effect,

(a) the Transaction Liens granted hereunder in favor of the Collateral Agent for the benefit of the Secured Parties in respect of the Collateral and the exercise of any right related thereto thereby shall be subject, in each case, to the terms of the Intercreditor Agreement;

(b) in the event of any direct conflict between the express terms and provisions of this Agreement and of the Intercreditor Agreement, the terms and provisions of the Intercreditor Agreement shall control; and

(c) notwithstanding anything to the contrary herein, any provision hereof that requires any Lien Grantor to (i) deliver any Collateral that consists of Pledged Collateral (as defined in the Intercreditor Agreement) to the Collateral Agent may be satisfied by the delivery of such Collateral by such Lien Grantor to the First Lien Agent for the benefit of the First Priority Lenders and the Collateral Agent in its capacity as the Second Lien Agent (as defined in the Intercreditor Agreement) for the benefit of the Second Priority Lenders (as defined in the Intercreditor Agreement) pursuant to Section 5.5 of the Intercreditor Agreement; or (ii) provide that the Collateral Agent have Control over such Collateral may be satisfied by causing the First Lien Agent to be provided with Control with respect to such Collateral of such Lien Grantor for the benefit of the First Priority Lenders and the Collateral Agent in its capacity as the Second Lien Agent for the benefit of the Second Priority Lenders pursuant to Section 5.5 of the Intercreditor Agreement.
