SECTION 9.                         REMEDIES.

9.1                               Generally.

(a)                                 If any Second Lien Event of Default shall have occurred and be continuing, the Collateral Agent may exercise in respect of the Collateral, in addition to all other rights and remedies provided for herein or otherwise available to it at law or in equity, all the rights and remedies of the Collateral Agent on default under the UCC (whether or not the UCC applies to the affected Collateral) to collect, enforce or satisfy any Secured Obligations then owing, whether by acceleration or otherwise, and also may pursue any of the following separately, successively or simultaneously:

(i)                                     require any Grantor to, and each Grantor hereby agrees that it shall at its expense and promptly upon request of the Collateral Agent forthwith, assemble all or part of the Collateral as directed by the Collateral Agent and make it available to the Collateral Agent at a place to be designated by the Collateral Agent that is reasonably convenient to both parties;

(ii)                                  enter onto the property where any Collateral is located and take possession thereof with or without judicial process;

(iii)                               prior to the disposition of the Collateral, store, process, repair or recondition the Collateral or otherwise prepare the Collateral for disposition in any manner to the extent the Collateral Agent deems appropriate; and

(iv)                              without notice except as specified below or under the UCC, sell, assign, lease, license (on an exclusive or nonexclusive basis) or otherwise dispose of the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, at such time or times and at such price or prices and upon such other terms as the Collateral Agent may deem commercially reasonable.

(b)                                 The Collateral Agent or any other Secured Party may be the purchaser of any or all of the Collateral at any public or private (to the extent the portion of the Collateral being privately sold is of a kind that is customarily sold on a recognized market or the subject of widely distributed standard price quotations) sale in accordance with the UCC and the Collateral Agent, as collateral agent for and representative of the Secured Parties, shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold at any such sale made in accordance with the UCC, to use and apply any of the Secured Obligations as a credit on account of the purchase price for any Collateral payable by the Collateral Agent at such sale.  Each purchaser at any such sale shall hold the property sold

29

absolutely free from any claim or right on the part of any Grantor, and each Grantor hereby waives (to the extent permitted by applicable law) all rights of redemption, stay and/or appraisal which it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted.  Each Grantor agrees that, to the extent notice of sale shall be required by law, at least 10 days notice to such Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification.  The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given.  The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.  Each Grantor agrees that it would not be commercially unreasonable for the Collateral Agent to dispose of the Collateral or any portion thereof by using Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets.  As long as the terms of any private sale of Collateral is commercially reasonable, each Grantor hereby waives any claims against the Collateral Agent arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price which might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree.  If the proceeds of any sale or other disposition of the Collateral are insufficient to pay all the Secured Obligations, Grantors shall be liable for the deficiency and the fees of any attorneys employed by the Collateral Agent to collect such deficiency.  Each Grantor further agrees that a breach of any of the covenants contained in this Section will cause irreparable injury to the Collateral Agent, that the Collateral Agent has no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section shall be specifically enforceable against such Grantor, and such Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no default has occurred giving rise to the Secured Obligations becoming due and payable prior to their stated maturities.  Nothing in this Section shall in any way limit the rights of the Collateral Agent hereunder.

(c)                                  The Collateral Agent may sell the Collateral without giving any warranties as to the Collateral.  The Collateral Agent may specifically disclaim or modify any warranties of title or the like.  This procedure will not be considered to adversely affect the commercial reasonableness of any sale of the Collateral.

(d)                                 The Collateral Agent shall have no obligation to marshal any of the Collateral.

9.2                               Application of Proceeds.  All proceeds received by the Collateral Agent in respect of any sale, any collection from, or other realization upon all or any part of the Collateral shall be applied in full or in part by the Collateral Agent in accordance with the Intercreditor Agreement.

9.3                               Sales on Credit.  If Collateral Agent sells any of the Collateral upon credit, Grantor will be credited only with payments actually made by purchaser and received by Collateral Agent and applied to indebtedness of the purchaser.  In the event the purchaser fails to pay for the Collateral, Collateral Agent may resell the Collateral and Grantor shall be credited with proceeds of the sale.

30

9.4                               Investment Related Property.  Each Grantor recognizes that, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws, the Collateral Agent may be compelled, with respect to any sale of all or any part of the Investment Related Property conducted without prior registration or qualification of such Investment Related Property under the Securities Act and/or such state securities laws, to limit purchasers to those who will agree, among other things, to acquire the Investment Related Property for their own account, for investment and not with a view to the distribution or resale thereof.  Each Grantor acknowledges that any such private sale may be at prices and on terms less favorable than those obtainable through a public sale without such restrictions (including a public offering made pursuant to a registration statement under the Securities Act) and, notwithstanding such circumstances, each Grantor agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner and that the Collateral Agent shall have no obligation to engage in public sales and no obligation to delay the sale of any Investment Related Property for the period of time necessary to permit the issuer thereof to register it for a form of public sale requiring registration under the Securities Act or under applicable state securities laws, even if such issuer would, or should, agree to so register it.  If the Collateral Agent determines to exercise its right to sell any or all of the Investment Related Property, upon written request, each Grantor shall and shall cause each issuer of any Pledged Stock to be sold hereunder, each partnership and each limited liability company from time to time to furnish to the Collateral Agent all such information as the Collateral Agent may reasonably request in order to determine the number and nature of interest, shares or other instruments included in the Investment Related Property which may be sold by the Collateral Agent in exempt transactions under the Securities Act and the rules and regulations of the Securities and Exchange Commission thereunder, as the same are from time to time in effect.

9.5                               Grant of Intellectual Property License. Solely for the purpose of enabling the Collateral Agent, during the continuance of a Second Lien Event of Default, to exercise rights and remedies under Section 9 hereof at such time as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies, and for no other purpose, each Grantor hereby grants to the Collateral Agent, to the extent assignable, an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to such Grantor), subject to sufficient rights to quality control and inspection in favor of such Grantor to avoid the risk of invalidation of such Intellectual Property, and subject to Collateral Agent’s use of all required statutory notices, and, in the case of Trade Secrets, written confidentiality agreement, to use, assign, license or sublicense any of the Intellectual Property now owned or hereafter acquired or owned by such Grantor, wherever the same may be located, other than Intellectual Property which the public disclosure of which would result in a Regulatory Exception, provided that such Grantor shall provide notice to Collateral Agent of any such determination along with such additional information as the Collateral Agent may reasonably request to verify to their satisfaction that such information is subject to a Regulatory Exception.

9.6                               Intellectual Property.

(a)                                 Anything contained herein to the contrary notwithstanding, in addition to the other rights and remedies provided herein, upon the occurrence and during the continuation of a Second Lien Event of Default:

(i)                                     the Collateral Agent shall have the right (but not the obligation) to bring suit or otherwise commence any action or proceeding in the name of any Grantor, the Collateral Agent or otherwise, in the Collateral Agent’s reasonable

31

discretion, to enforce any Intellectual Property owned by such Grantor, in which event such Grantor shall, at the request of the Collateral Agent, do any and all lawful acts and execute any and all documents reasonably required by the Collateral Agent in aid of such enforcement, and such Grantor shall promptly, upon demand, reimburse and indemnify the Collateral Agent as provided in Section 12 hereof in connection with the exercise of its rights under this Section 9.6;

(ii)                                  upon written demand from the Collateral Agent, each Grantor shall grant, assign, convey or otherwise transfer to the Collateral Agent or such Collateral Agent’s designee all of such Grantor’s right, title and interest in and to any Intellectual Property that is Collateral and shall execute and deliver to the Collateral Agent such documents as are necessary or appropriate to carry out the intent and purposes of this Agreement;

(iii)                               each Grantor agrees that such an assignment and/or recording shall be applied to reduce the Secured Obligations outstanding only to the extent that the Collateral Agent (or any other Secured Party) receives cash proceeds in respect of the sale of, or other realization upon, any such Intellectual Property;

(iv)                              within five Business Days after written notice from the Collateral Agent, each Grantor shall make available to the Collateral Agent, to the extent within such Grantor’s power and authority, such personnel in such Grantor’s employ, to permit such Grantor to continue, directly or indirectly, to produce, advertise and sell the products and services sold or delivered by such Grantor under or in connection with any Trademarks or Trademark Licenses, such persons to be available to perform their prior functions on the Collateral Agent’s behalf and to be compensated by the Collateral Agent at such Grantor’s expense on a per diem, pro rata basis consistent with the salary and benefit structure applicable to each; and

(v)                                 the Collateral Agent shall have the right to notify, or require each Grantor to notify, any obligors with respect to amounts due or to become due to such Grantor in respect of any Intellectual Property of such Grantor, of the existence of the security interest created herein, to direct such obligors to make payment of all such amounts directly to the Collateral Agent, and, upon such notification and at the expense of such Grantor, to enforce collection of any such amounts and to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as such Grantor might have done;

(1)                                 all amounts and proceeds (including checks and other instruments) received by Grantor in respect of amounts due to such Grantor in respect of the Collateral or any portion thereof shall be received in trust for the benefit of the Collateral Agent hereunder, shall be segregated from other funds of such Grantor and shall be forthwith paid over or delivered to the Collateral Agent in the same form as so received (with any necessary endorsement) to be held as cash Collateral and applied as provided by Section 9.7 hereof; and

(2)                                 Grantor shall not adjust, settle or compromise the amount or payment of any such amount or release wholly or partly any obligor with respect thereto or allow any credit or discount thereon.

(b)  If any Second Lien Event of Default shall have occurred and be continuing, the Collateral Agent may apply the balance from any Deposit Account or instruct the bank at which any Deposit Account is maintained to pay the balance of any Deposit Account to or for the benefit of the Collateral Agent.

SECTION 10.                  COLLATERAL AGENT; INTERCREDITOR AGREEMENT.

The Collateral Agent has been appointed to act as Collateral Agent hereunder by the Secured Parties.  In furtherance of the foregoing provisions of this Section, each Secured Party, by its acceptance of the benefits hereof, agrees that it shall have no right individually to realize upon any of the Collateral hereunder, it being understood and agreed by such Secured Party that all rights and remedies hereunder may be exercised solely by the Collateral Agent for the benefit of Secured Parties in accordance with the terms of this Section.  Notwithstanding anything herein to the contrary, the lien and security interest granted to the Collateral Agent for the benefit of the Secured Parties pursuant to this Agreement and the exercise of any right or remedy by the Collateral Agent for the benefit of the Secured Parties hereunder are subject to the terms of the Intercreditor Agreement.  In the event of any conflict between the terms of the Intercreditor Agreement and this Agreement, the terms of the Intercreditor Agreement will govern and control.

33

SECTION 11.                  CONTINUING SECURITY INTEREST; TRANSFER OF LOANS.

This Agreement shall create a continuing security interest in the Collateral and shall remain in full force and effect until as provided in the Intercreditor Agreement, be binding upon each Grantor, its successors and assigns, and inure, together with the rights and remedies of the Collateral Agent hereunder, to the benefit of the Collateral Agent and its successors, transferees and assigns.  Without limiting the generality of the foregoing, but subject to the terms of the applicable Second Lien Documents, any lender under a Second Lien Document may assign or otherwise transfer any loans or extensions of credit held by it to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to Secured Parties herein or otherwise.  Upon the occurrence of the conditions set forth in the Intercreditor Agreement, the security interest granted hereby shall automatically terminate hereunder and of record and all rights to the Collateral shall revert to the Grantors.  Upon any such termination the Collateral Agent shall, at the Grantors’ expense, execute and deliver to the Grantors or otherwise authorize the filing of such documents as the Grantors shall reasonably request, including financing statement amendments to evidence such termination.

SECTION 12.                  STANDARD OF CARE; COLLATERAL AGENT MAY PERFORM.

The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers.  Except for the exercise of reasonable care in the custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.  The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property.  Neither the Collateral Agent nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or otherwise.  If any Grantor fails to perform any agreement contained herein, the Collateral Agent may itself perform, or cause performance of, such agreement, and the expenses of the Collateral Agent incurred in connection therewith shall be payable by each Grantor in accordance with the Intercreditor Agreement.

SECTION 13.                  MISCELLANEOUS.

Any notice required or permitted to be given under this Agreement shall be given in accordance with Section 7.8 of the Intercreditor Agreement.  No failure or delay on the part of the Collateral Agent in the exercise of any power, right or privilege hereunder or under any other Second Lien Document shall impair such power, right or privilege or be construed to be a waiver of any default or acquiescence therein, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other power, right or privilege.  All rights and remedies existing under this Agreement and the other Second Lien Documents are cumulative to, and not exclusive of, any rights or remedies otherwise available.  In case any provision in or obligation under this Agreement shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.  All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact

34

that it would be permitted by an exception to, or would otherwise be within the limitations of, another covenant shall not avoid the occurrence of a Secured Debt Default with respect to any Second Lien Debt if such action is taken or condition exists.  This Agreement shall be binding upon and inure to the benefit of the Collateral Agent and the Grantors and their respective successors and assigns.  No Grantor shall, without the prior written consent of the Collateral Agent given in accordance with the Intercreditor Agreement, assign any right, duty or obligation hereunder.  This Agreement, the Intercreditor Agreement and the other Second Lien Documents embody the entire agreement and understanding between the Grantors and the Collateral Agent and supersede all prior agreements and understandings between such parties relating to the subject matter hereof and thereof.  Accordingly, such agreements may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties.  There are no unwritten oral agreements between the parties.  This Agreement may be executed in one or more counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument; signature pages may be detached from multiple separate counterparts and attached to a single counterpart so that all signature pages are physically attached to the same document.  Delivery of an executed signature page of this Agreement by facsimile or other electronic transmission (e.g., “pdf” or “tif” format) shall be effective as delivery of a manually executed counterpart hereof.

THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER (INCLUDING, WITHOUT LIMITATION, ANY CLAIMS SOUNDING IN CONTRACT LAW OR TORT LAW ARISING OUT OF THE SUBJECT MATTER HEREOF) SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES THEREOF THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAW OF THE STATE OF NEW YORK (OTHER THAN ANY MANDATORY PROVISIONS OF THE UCC RELATING TO THE LAW GOVERNING PERFECTION AND THE EFFECT OF PERFECTION OF THE SECURITY INTEREST).

THE PROVISIONS OF THE INTERCREDITOR AGREEMENT UNDER THE HEADINGS “CONSENT TO JURISDICTION” AND “WAIVER OF JURY TRIAL” ARE INCORPORATED HEREIN BY THIS REFERENCE AND SUCH INCORPORATION SHALL SURVIVE ANY TERMINATION OF THE INTERCREDITOR AGREEMENT.

NO CLAIM MAY BE MADE BY ANY GRANTOR AGAINST THE COLLATERAL AGENT, THE SECOND LIEN ADMINISTRATIVE AGENT OR ANY AFFILIATE, DIRECTOR, OFFICER, EMPLOYEE, COUNSEL, REPRESENTATIVE, AGENT, OR ATTORNEY-IN-FACT OF ANY OF THEM FOR ANY SPECIAL, INDIRECT, CONSEQUENTIAL, OR PUNITIVE DAMAGES IN RESPECT OF ANY CLAIM FOR BREACH OF CONTRACT OR ANY OTHER THEORY OF LIABILITY ARISING OUT OF OR RELATED TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, OR ANY ACT, OMISSION, OR EVENT OCCURRING IN CONNECTION HEREWITH, AND EACH GRANTOR HEREBY WAIVES, RELEASES, AND AGREES NOT TO ▇▇▇ UPON ANY CLAIM FOR SUCH DAMAGES, WHETHER OR NOT ACCRUED AND WHETHER OR NOT KNOWN OR SUSPECTED TO EXIST IN ITS FAVOR.
