Section 2.01 Guarantee. Subject to the terms of the Intercreditor Agreement and the First Lien Guarantee and Security Agreement, each Guarantor hereby jointly and severally guarantees to the Second Lien Secured Parties the performance and prompt payment in full when due (whether at stated maturity, upon acceleration, upon any optional or mandatory prepayment or otherwise) of the Second Lien Guaranteed Obligations in each case strictly in accordance with its terms. Each Guarantor hereby further agrees that if any Borrower fails to pay in full when due (whether at stated maturity, upon acceleration, upon any optional or mandatory prepayment or otherwise) all or any part of the Second Lien Guaranteed Obligations, such Guarantor will immediately pay the same, without any demand or notice whatsoever, and that, in the case of any extension of time of payment or renewal of all or any part of the Second Lien Guaranteed Obligations, such Guarantor will timely pay the same in full when due (whether at extended maturity, upon acceleration or otherwise) in accordance with the terms of that extension or renewal. This Agreement is irrevocable and unconditional in nature and is made with respect to any Second Lien Guaranteed Obligations now existing or in the future arising. The liability of each Guarantor under this Agreement shall continue until full satisfaction of all the Second Lien Guaranteed Obligations. This Agreement is a guarantee of due and punctual payment and performance and is not merely a guarantee of collection.

Section 2.02 Obligations Unconditional. The obligations of each Guarantor under Section 2.01 shall be continuing, irrevocable, primary, absolute and unconditional irrespective of the value, genuineness, validity, regularity or enforceability of the FW Credit Facilities as applicable, any Basic Document or any other agreement or instrument referred to therein, or any substitution, release or exchange of any other guarantee of or security for any of the Second Lien Guaranteed Obligations, and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being the intent of this Section 2.02 that the obligations of each Guarantor hereunder shall be absolute and unconditional under any and all circumstances. Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not alter, limit or impair the liability of any Guarantor hereunder, which shall remain absolute and unconditional as described above without regard to and not be released, discharged or in any way affected (whether in full or in part) by:

(a) any modification or amendment (including without limitation by way of amendment, extension, renewal, novation or waiver), or any acceleration or other change in the time for payment or performance of the terms of all or any part of the Second Lien Guaranteed Obligations or any Basic Document or any other agreement or instrument whatsoever relating thereto;

(b) any release, termination, waiver, abandonment, lapse or expiration, subordination or enforcement of the liability of any Guarantor hereunder or of any other guarantee of all or any part of the Second Lien Guaranteed Obligations;

(c) any exchange, substitution, release, non-perfection or impairment of any Collateral securing payment of any Second Lien Guaranteed Obligation;

(d) any release of any other Person (including, without limitation, any other guarantor with respect to the Second Lien Guaranteed Obligations) from any personal liability with respect to all or any part of the Second Lien Guaranteed Obligations;

(e) any settlement, compromise, release, liquidation or enforcement, upon such terms and in such manner as applicable law may dictate, of all or any part of the Second Lien Guaranteed Obligations or any other guarantee of (including without limitation any letter of credit issued with respect to) all or any part of the Second Lien Guaranteed Obligations;

(f) any agreement not to pursue or enforce or any failure to pursue or enforce (whether voluntarily or involuntarily as a result of operation of law, court order or otherwise) any right or remedy in respect of any Second Lien Guaranteed Obligation, any guarantee or other liability in respect thereof or any Collateral or other security for any of the foregoing; any sale, exchange, release, substitution, compromise or other action in respect of any such Collateral or other security; or any failure to create, protect, perfect, secure, insure, continue or maintain any liens in any such Collateral or other security;

(g) the exercise of any right or remedy available under the Basic Documents or the documents pursuant to which any other Obligation is incurred, as applicable, at law, in equity or otherwise in respect of any Collateral or other security for any Guaranteed Obligation or for any guarantee or other liability in respect thereof, in any order and by any manner thereby permitted, including, without limitation, foreclosure on any such Collateral or other security by any manner of sale thereby permitted, whether or not every aspect of such sale is commercially reasonable;

(h) any manner of application of any payments by or amounts received or collected from any Person, by whomsoever paid and howsoever realized, whether in reduction of any Second Lien Guaranteed Obligations or any other obligations of the Borrowers or any other Person directly or indirectly liable for any Second Lien Guaranteed Obligations, regardless of what Second Lien Guaranteed Obligations may remain unpaid after any such application;

(i) any other circumstance that might otherwise constitute a legal or equitable discharge of, or a defense, set-off or counterclaim available to, the Borrowers, any Guarantor or a surety or guarantor generally, other than irrevocable payment, performance, satisfaction or discharge in full (in accordance with the terms of the applicable Basic Document);

(k) any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Borrowers or its assets or any resulting release or discharge of any Guaranteed Obligation. Each Guarantor acknowledges and agrees that the Second Lien Guaranteed Obligations include interest on the Second Lien Guaranteed Obligations at the applicable rate therefor under the Basic Documents, which accrues after the commencement of any such proceeding (or, if interest on any portion of the Second Lien Guaranteed Obligations ceases to accrue by operation of law by reason of the commencement of said proceeding, such Second Lien Guaranteed Obligations include the interest which would have accrued on such portion of the Second Lien Guaranteed Obligations if said proceedings had not been commenced), since it is the intention of the parties that the amount of the Second Lien Guaranteed Obligations which is guaranteed by each Guarantor pursuant to this Agreement should be determined without regard to any rule of law or order which may relieve the Borrowers of any portion of the Second Lien Guaranteed Obligations. The Guarantors will permit any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit of creditors or similar person to pay the Collateral Agent, or allow the claim of the Collateral Agent in respect of, interest which would have accrued after the date on which such proceeding is commenced. Notwithstanding the above, so long as any Second Lien Guaranteed Obligation shall remain outstanding, no Guarantor shall, without the prior written consent of the Collateral Agent, commence or join with any other person in commencing any bankruptcy, reorganization or insolvency proceedings of or against any Borrower.

(l) Should any money due or owing under this Agreement not be recoverable from any Guarantor for any reason, whether by operation of law or otherwise, then, in any such case, such money shall nevertheless be recoverable by the Collateral Agent from such Guarantor as though such Guarantor were the principal debtors in respect thereof and not merely a guarantor and shall be paid by such Guarantor forthwith.

Section 2.03 Waiver.

(a) Each Guarantor hereby expressly waive promptness, diligence, presentment, demand for payment or performance and protest; filing of claims with any court; any proceeding to enforce any provision of the Basic Documents; notice of acceptance of and reliance on this Agreement by the Second Lien Secured Parties, notice of the creation of any Second Lien Guaranteed Obligations of the Borrowers, and any other notice whatsoever; any requirement that the Collateral Agent exhaust any right, remedy, power or privilege or proceed or take any other action against the Borrowers under any Basic Document, or any lien or encumbrance on, or any claim of payment against, any property of the Borrowers or any other agreement or instrument referred to therein, or any other Person under any other guarantee of, or lien securing, or claim for payment of, any of the Second Lien Guaranteed Obligations; any right to require a

proceeding by the Collateral Agent first against the Borrowers whether to marshal any assets or to exhaust any right or take any action against the Borrowers or any other Person or any Collateral or otherwise, any diligence in collection or protection for realization upon any Guaranteed Obligation; any obligation hereunder or any collateral security for any of the foregoing; any right of protest, presentment, notice or demand whatsoever, and any claims of waiver, release, surrender, alteration or compromise and all defenses, set-offs counterclaims, recoupments, reductions, limitations, impairments or terminations, whether arising hereunder or otherwise. Each Guarantor further waives (i) any requirement that the Borrowers or any other Person be joined as a party to any proceeding for the enforcement by the Collateral Agent of any of the Second Lien Guaranteed Obligations and (ii) the filing of claims by the Collateral Agent in the event of the receivership or bankruptcy of any Borrower. The Collateral Agent shall have the right to bring suit directly against any Guarantor with respect to the obligations owed to the Collateral Agent hereunder either prior to or concurrently with any lawsuit against, or without bringing any suit against any Borrower or any other Person.

(b) The enforceability and effectiveness of this Agreement and the liability of each Guarantor, and the rights, remedies, powers and privileges of the Collateral Agent under this Agreement shall not be affected, limited, reduced, discharged or terminated, and each Guarantor hereby expressly waives to the fullest extent permitted by law any defense now or in the future arising, by reason of:

(iii) the illegality, invalidity or unenforceability of any security or guarantee for all or any part of the Second Lien Guaranteed Obligations or the lack of perfection or continuing perfection or failure of the priority of any lien or encumbrance on any Collateral for all or any part of the Second Lien Guaranteed Obligations;

(iv) the cessation, for any cause whatsoever, of the liability of any Guarantor for all or any part of the Second Lien Guaranteed Obligations (other than by reason of the full payment and performance of all Second Lien Guaranteed Obligations);

(v) any failure of the Collateral Agent to give notice of sale or other disposition of any Collateral (including any notice of any judicial or non-

judicial foreclosure or sale of any interest in real property serving as Collateral for all or any part of the Second Lien Guaranteed Obligations) for all or any part of the Second Lien Guaranteed Obligations to the Borrowers, any Guarantor or any other Person or any defect in, or any failure by the Borrowers, any Guarantor or any other Person to receive, any notice that may be given in connection with any sale or disposition of any Collateral;

(vi) any failure of the Collateral Agent to comply with applicable laws in connection with the sale or other disposition of any Collateral for all or any part of the Second Lien Guaranteed Obligations;

(vii) any judicial or non-judicial foreclosure or sale of, or other election of remedies with respect to, any interest in real property or other Collateral serving as security for all or any part of the Second Lien Guaranteed Obligations, even though such foreclosure, sale or election of remedies may impair the subrogation rights of either the Borrowers or any Guarantor or may preclude the Borrowers or any Guarantor from obtaining reimbursement, contribution, indemnification or other recovery from the other or any other Person and even though the Borrowers or such Guarantor may not, as a result of such foreclosure, sale or election of remedies, be liable for any deficiency;

(viii) any act or omission of the Collateral Agent or any other Person that directly or indirectly results in or aids the discharge or release of the Borrowers of any part of the Second Lien Guaranteed Obligations or any security or guarantee (including any letter of credit) for all or any part of the Second Lien Guaranteed Obligations by operation of law or otherwise;

(ix) any counterclaim, set-off or other claim which the Borrowers or any other guarantor of all or any part of the Second Lien Guaranteed Obligations has or alleges to have with respect to all or any part of the Second Lien Guaranteed Obligations;

Each Guarantor agrees that it will indemnify the Collateral Agent on demand for all reasonable and properly documented costs and expenses (including reasonable and properly documented fees of counsel) incurred by the Collateral Agent in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law.

Section 2.05 Subrogation.

(a) To the extent of any payments made under this Agreement, each Guarantor shall be subrogated to the rights of the Lenders receiving such payments, but each Guarantor covenants and agrees that such right of subrogation shall be subordinate in right of payment to the rights of any Lenders for which full payment has not been made or provided for and, to that end, each Guarantor agrees not to claim or enforce any such right of subrogation or any right of set-off or any other right which may arise on account of any payment made by such Guarantor in accordance with the provisions of this Agreement unless and until all of the Second Lien Guaranteed Obligations owned or held by Persons other than such Guarantor and all other sums due or payable under this Agreement have been fully, finally and indefeasibly, paid and discharged or payment therefor has been provided.

(b) Subject to the provisions of Section 2 of the Intercreditor Agreement, if any amount shall be paid to any Guarantor on account of such subrogation rights at any time prior to the indefeasible and unconditional payment, discharge or performance in full of the Second Lien Guaranteed Obligations and all other amounts payable under this Agreement, such amount shall be held in trust for the benefit of the Collateral Agent and shall forthwith be paid to the Collateral Agent to be credited and applied upon and against the Second Lien Guaranteed Obligations, to the extent then

matured, in accordance with the terms of the relevant Basic Documents, or, to the extent not then matured or existing, be held by the Collateral Agent as collateral security for the Second Lien Guaranteed Obligations.

Section 2.06 Remedies. Subject to the terms of the Intercreditor Agreement, each Guarantor agrees that, as between such Guarantor and the Collateral Agent, any obligations of the Borrowers to the Second Lien Secured Parties under any of the Basic Documents may be declared to be forthwith due and payable notwithstanding any stay, injunction or other prohibition preventing such declaration (or such obligations from becoming automatically due and payable) against the Borrowers and that, in the event of such declaration (or such obligations being deemed to have become automatically due and payable), such obligations (whether or not due and payable by the Borrowers) shall forthwith become due and payable by such Guarantor for purposes of this Agreement. For the avoidance of doubt, it is understood and agreed that any amount payable by a Guarantor pursuant to the immediately preceding sentence is intended to be applied to the payment or prepayment (as the case may be) of the Second Lien Guaranteed Obligations. Each of the obligations of each Guarantor under this Agreement is separate and independent of the Second Lien Guaranteed Obligations, and each Guarantor agrees that a separate action or actions may be brought and prosecuted by the Collateral Agent against such Guarantor to enforce this Agreement, irrespective of whether any action is brought by the Collateral Agent against the Borrowers under any relevant Basic Document or whether the Borrowers is joined in any such action or actions.

Section 2.07 Continuing Guarantee. The guarantee in this Article II is a continuing, absolute and unconditional guarantee of payment and shall remain in full force and effect until the date when all Second Lien Guaranteed Obligations whenever arising have been paid in full in cash and all obligations of each Guarantor hereunder shall have been paid in full in cash.

Section 3.08 Special Provisions Relating to Certain Collateral.

(a) Intellectual Property.

(i) Subject to the terms of the Intercreditor Agreement and the First Lien Guarantee and Security Agreement, for the purpose of enabling the Collateral Agent to exercise the rights, remedies, powers and privileges under Section 6.01 at that time or times as the Collateral Agent is lawfully entitled to exercise those rights, remedies, powers and privileges, and for no other purpose, each Guarantor hereby grants to the Collateral Agent, to the extent assignable, an irrevocable, nonexclusive license (exercisable without payment of royalty or other compensation to such Guarantor) to use, assign, license or sublicense any of the Intellectual Property of such Guarantor, together with reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer programs used for the compilation or printout of those items.

(ii) Notwithstanding anything contained herein to the contrary, but subject to the terms of the FWA4 Promissory Note, so long as no Second Lien Event of Default shall have occurred and be continuing, each Guarantor will be permitted to exploit, use, enjoy, protect, license, sublicense, assign, sell, dispose of or take other actions with respect to the Intellectual Property in the ordinary course of the business of the Guarantor. In furtherance of the foregoing, unless a Second Lien Event of Default shall have occurred and be continuing and subject

to the terms of the Intercreditor Agreement, the Collateral Agent shall from time to time, upon the request of any Guarantor, execute and deliver any instruments, certificates or other documents, in the form so requested, that such Guarantor shall have certified are appropriate (in its judgment) to allow it to take any action permitted above (including relinquishment of the license provided pursuant to clause (i) immediately above as to any specific Intellectual Property). Further, upon the payment in full of all of the Second Lien Guaranteed Obligations or earlier expiration of this Agreement or release of the Guarantor Collateral, the Collateral Agent shall grant back to each Guarantor the license granted pursuant to clause (i) immediately above.

Section 3.09 Use of Guarantor Collateral. So long as no Second Lien Event of Default has occurred and is continuing, and subject to the terms of the Intercreditor Agreement and the First Lien Guarantee and Security Agreement, each Guarantor shall be entitled to possess the Guarantor Collateral, subject to the rights, remedies, powers and privileges of the Collateral Agent under Articles III and VI.

Except as expressly provided for in the Basic Documents, the Collateral Agent shall not have any duty, obligation or liability under those contracts and agreements or with respect to any permit included in the Guarantor Collateral by reason of this Agreement, or any other Basic Document, nor shall the Collateral Agent be obligated to perform any of the duties or obligations of either Guarantor under any such contract or agreement or any such permit or to take any action to collect or enforce any claim (for payment) under any such contract or agreement or permit.

(c) No lien granted by this Agreement in any Guarantor’s right, title and interest in any contract, agreement or permit shall be deemed to be a consent by the Collateral Agent to any such contract, agreement or permit.

(b) Upon the occurrence of the Mars Hill Transfer and the Initial Steel Winds Transfer and the creation and perfection of liens in connection with each of the Mars Hill Project and the Steel Winds Project as required pursuant to the FW Credit Facilities, the grant of Guarantor Collateral hereunder shall terminate with respect to and no longer secure the Holdings Guaranteed Obligations.

Upon the termination of the FWA1 Second Lien Guaranteed Obligations or the Holdings Guaranteed Obligations, as applicable, the Collateral Agent shall execute and deliver to each Guarantor, at such Guarantor’s expense, such UCC termination statements and other documentation as shall be reasonably requested by such Guarantor to effect the termination and release of the liens created under this Agreement with respect to the FWA1 Second Lien Guaranteed Obligations or the Holdings Guaranteed Obligations, as applicable.

Section 3.12 [Intentionally Omitted].

Section 3.13 Commercial Tort Claims. Subject to the terms of the Intercreditor Agreement and the First Lien Guarantee and Security Agreement, each Guarantor agrees that, if it shall acquire any interest in any Commercial Tort Claim with a potential value in excess of $500,000 (whether from another Person or because such Commercial Tort Claim shall have come into existence), (i) such Guarantor shall, immediately upon such acquisition, deliver to the Collateral Agent, in each case in form and substance reasonably satisfactory to the Collateral Agent, a notice of the existence and nature of such Commercial Tort Claim and deliver a supplement to Annex 5 containing a specific description of such Commercial Tort Claim, certified by such Guarantor as true, correct and complete, (ii) the provision of Section 3.01 shall apply to such Commercial Tort Claim (and such Guarantor authorizes the Collateral Agent to supplement such annex with a description of such Commercial Tort Claim if such Guarantor fails to deliver the supplement described in clause (i)), and (iii) such Guarantor shall execute and deliver to the Collateral Agent, in each case in form and substance reasonably satisfactory to the Collateral Agent, any certificate, agreement and other document, and take all other action, deemed by the Collateral Agent to be reasonably necessary or appropriate for the Collateral Agent to obtain a first-priority, or second-priority, as appropriate, perfected security interest in all such Commercial Tort Claims.

(e) The Collateral Agent shall have, and in its discretion may exercise, all of the rights, remedies, powers and privileges with respect to the Guarantor Collateral of a secured party under the UCC (whether or not the UCC is in effect in the jurisdiction where such rights, remedies, powers and privileges are asserted) and such additional rights, remedies, powers and privileges to which a secured party is entitled under the laws in effect in any jurisdiction where any rights, remedies, powers and privileges in respect of this Agreement or the Guarantor Collateral may be asserted, including the right, to the maximum extent permitted by law, to exercise all voting, consensual and other powers of ownership pertaining to the Guarantor Collateral as if the Collateral Agent were the sole and absolute owner of the Guarantor Collateral (and each Guarantor agrees to take all such action as may be appropriate to give effect to such right);

(f) The Collateral Agent in its discretion may, to the full extent provided by law, have a court having jurisdiction appoint a receiver, which receiver shall take charge and possession of and protect, preserve, replace and repair the Guarantor Collateral or any part thereof, and manage and operate the same, and receive and collect all rents, income, receipts, royalties, revenues, issues and profits therefrom. Each Guarantor irrevocably consents and shall be deemed to have hereby irrevocably consented to the appointment thereof, and upon such appointment, such Guarantor shall immediately deliver possession of such Guarantor Collateral to the receiver. Each Guarantor also irrevocably consents to the entry of an order authorizing such receiver to invest upon interest any funds held or received by the receiver in connection with such receivership. The Collateral Agent shall be entitled to such appointment as a matter of right, if it shall so elect, without the giving of notice to any other party and without regard to the adequacy of the security of the Guarantor Collateral; and

(g) The Collateral Agent in its discretion may enforce one or more remedies hereunder, successively or concurrently, and such action shall not operate to estop or prevent the Collateral Agent from pursuing any other or further remedy which it may have hereunder or by law, and any repossession or retaking or sale of the Guarantor Collateral pursuant to the terms hereof shall not operate to release any Guarantor until full and final payment of any deficiency has been made in cash. Such Guarantor shall reimburse the Collateral Agent upon demand for, or the Collateral Agent may apply any proceeds of Guarantor Collateral to, the costs and expenses (including reasonable attorneys’ fees, transfer taxes and any other charges) incurred by the Collateral Agent in connection with any sale, disposition, repair, replacement, alteration, addition, improvement or retention of any Guarantor Collateral hereunder.

Section 6.02 Deficiency. If the proceeds of, or other realization upon, the Guarantor Collateral by virtue of the exercise of remedies under Section 6.01 are insufficient to cover the costs and expenses of such exercise and the payment in full of the Second Lien Guaranteed Obligations, such Guarantor shall remain liable for any deficiency.

Section 6.03 Private Sale.

(a) Subject to the terms of the Intercreditor Agreement, the Collateral Agent shall incur no liability as a result of the sale, lease or other disposition of all or any part of the Guarantor Collateral at any private sale pursuant to Section 6.01 conducted in a commercially reasonable manner. Each Guarantor hereby waives any claims against the Collateral Agent arising by reason of the fact that the price at which the Guarantor Collateral may have been sold at such a private sale was less than the price which might have been obtained at a public sale or was less than the aggregate amount of the Second Lien Guaranteed Obligations, even if the Collateral Agent accepts the first offer received and does not offer the Guarantor Collateral to more than one offeree.

(b) Each Guarantor recognizes that, by reason of certain prohibitions contained in the Securities Act of 1933, as amended, and applicable state securities laws, the Collateral Agent may be compelled, with respect to any sale of all or any part of the Guarantor Collateral, to limit purchasers to those who will agree, among other things, to acquire the Guarantor Collateral for their own account, for investment and not with a view to distribution or resale. Each Guarantor acknowledges that any such private sales may be at prices and on terms less favorable to the Collateral Agent than those obtainable through a public sale without such restrictions, and, notwithstanding such circumstances, 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 Guarantor Collateral for the period of time necessary to permit the respective issuer of such Guarantor Collateral to register it for public sale.

Section 6.04 Cash Proceeds of Guarantor Collateral.

(a) If so requested by the Collateral Agent at any time after the occurrence and during the continuation of a Second Lien Event of Default, and subject to the terms of the Intercreditor Agreement and the First Lien Guarantee and Security Agreement, such Guarantor shall instruct all account debtors in respect of Accounts, Chattel Paper and General Intangibles and all obligors on Instruments to make all payments in respect thereof either (i) directly to the Collateral Agent (by instructing that such payments be remitted to a post office box which shall be in the name and under the control of the Collateral Agent) or (ii) to one or more other banks in the United States of America (by instructing that such payments be remitted to a post office box which shall be in the name and under the control of the Collateral Agent) under arrangements, in form and substance reasonably satisfactory to the Collateral Agent, pursuant to which such Guarantor shall have irrevocably instructed such other bank (and such other bank shall have agreed) to remit all proceeds of such payments directly to the Collateral Agent for deposit in accordance with the terms of the FW Credit Facilities.

(b) In addition to the foregoing, and subject to the terms of the Intercreditor Agreement, each Guarantor agrees that, at any time after the occurrence and during the continuation of a Second Lien Event of Default, if the proceeds of any Guarantor Collateral hereunder (including the payments made in respect of Accounts)

shall be received by it, such Guarantor shall, as promptly as possible deposit such proceeds in accordance with the terms of the FW Credit Faculties. Until so deposited, all such proceeds shall be held in trust by such Guarantor for and as the property of the Collateral Agent and shall not be commingled with any other funds or property of such Guarantor.

Section 6.05 Application of Proceeds. The Proceeds of, or other realization upon, all or any part of the Guarantor Collateral shall be applied in accordance with the Intercreditor Agreement. To the extent that the Proceeds of, or other realization upon, all or any part of the Guarantor Collateral may be applied towards the Second Lien Guaranteed Obligations hereunder, except as otherwise expressly provided in this Agreement, the Proceeds of, or other realization upon, all or any part of the Guarantor Collateral by virtue of the exercise of remedies under Section 6.01, and any other cash at the time held by the Collateral Agent or under this Article VI, shall be applied by the Collateral Agent:

First, to the payment of documented, out-of-pocket costs and expenses of such exercise of remedies, including documented, out-of pocket costs and expenses of the Collateral Agent, and documented fees and out-of-pocket expenses of its agents and reasonable fees and expenses of its counsel and all documented, out-of-pocket other expenses incurred and advances made by the Collateral Agent in that connection;

Next, to the payment in full of the remaining Second Lien Guaranteed Obligations equally ratably in accordance with their respective amounts then due and owing; and

Finally, subject to the rights of any other holder of any lien in the relevant Guarantor Collateral, to the payment of such Guarantor, or its respective successors or assigns, or as a court of competent jurisdiction may direct, of any surplus then remaining.

EACH GUARANTOR HEREBY AGREES THAT SERVICE OF PROCESS IN ANY SUCH PROCEEDING MAY BE EFFECTED BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL (OR ANY SUBSTANTIALLY SIMILAR FORM OF MAIL), POSTAGE PREPAID, TO IT AT ITS ADDRESS SPECIFIED IN SECTION 7.01 OR AT SUCH OTHER ADDRESS OF WHICH THE COLLATERAL AGENT SHALL HAVE RECEIVED NOTICE PURSUANT TO SECTION 7.01.

Section 7.11 Independent Obligations. Each Guarantor’s obligations under this Agreement are independent of those of any other Person. The Collateral Agent may bring a separate action against any Guarantor without first proceeding against the Borrowers or any other Person or any other security held by the Collateral Agent and without pursuing any other remedy.

Section 7.12 Expenses. Each Guarantor agrees to pay or to reimburse the Collateral Agent for all reasonable documented, out-of-pocket costs and expenses (including reasonable attorney’s fees and reasonably documented out-of-pocket expenses) that may be incurred by the Collateral Agent in any effort to enforce any of the provisions of Article VI, or any of the obligations of such Guarantor in respect of the Guarantor Collateral or in connection with (a) the preservation of the liens on, or the rights of the Collateral Agent to the Guarantor Collateral pursuant to this Agreement or the other Security Agreements or (b) any actual or attempted sale, lease, disposition, exchange, collection, compromise, settlement or other realization in respect of, or care of, the Guarantor Collateral, including all such costs and expenses (and reasonable attorney’s fees and reasonable documented out-of-pocket expenses) incurred in any bankruptcy, reorganization, workout or other similar proceeding.

Section 7.13 Duty of the Collateral Agent. The Collateral Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither it not any of its officers, directors, employees or agents shall be responsible to any Guarantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct. Except for reasonable care and preservation 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 the collection or protection of the Collateral or any income thereon, nor as to the preservation of rights against prior parties, nor as to the preservation of any rights pertaining thereto beyond the safe custody thereof.

Section 7.14 Additional Grantors. Each Subsidiary of CSSW that is required to become a party to the First Lien Guarantee and Security Agreement on or after the Subsequent Closing Date (as such term is defined in the AIMCO Loan Agreement) pursuant to the AIMCO Loan Agreement shall become a Guarantor for all purposes of this Agreement upon execution and delivery by such Subsidiary of an Assumption Agreement in the form of Exhibit II hereto.

Section 7.15 Intercreditor Agreement. Notwithstanding anything to the contrary contained herein, the liens, security interests and rights granted pursuant to this Agreement or any other security document shall be as set forth in, and subject to the terms and conditions of (and the exercise of any right or remedy by the Collateral Agent hereunder shall be subject to the terms and conditions of), the Intercreditor Agreement. In the event of any conflict between this Agreement or any other security document and the Intercreditor Agreement, the Intercreditor Agreement shall control, and no right, power, or remedy granted to the Collateral Agent hereunder shall be exercised by the Collateral Agent, and no direction shall be given by the Collateral Agent in contravention of the Intercreditor Agreement. Without limiting the generality of the foregoing, and notwithstanding anything herein to the contrary, all rights and remedies of the Collateral Agent (and the Second Lien Secured Parties) shall be subject to the terms of the Intercreditor Agreement, and, with respect to any Guarantor Collateral in favor of the Aimco Agent and Aimco Lenders (the “First Lien Collateral”) until the Discharge of Aimco Lien Indebtedness (as such term is defined in the Intercreditor Agreement), any obligation of the Borrower and the Guarantors hereunder with respect to the delivery or control of any First Lien Collateral, the novation of any lien on any certificate of title, bill of lading or other document, the giving of any notice to any bailee or other Person, the provision of voting rights or the obtaining of any consent of any Person shall be deemed to be satisfied if the Borrower or such Guarantor, as applicable, complies with the requirements of the similar provision of the First Lien Guarantee and Security Agreement. Until the Discharge of Aimco Lien Indebtedness (as such term is defined in the Intercreditor Agreement), the delivery of any First Lien Collateral to, or the control of any First Lien Collateral by, the Aimco Agent pursuant to the Aimco Loan Documents (as such term is defined in the Intercreditor Agreement) shall satisfy any delivery or control requirement hereunder; provided, however, the delivery of any First Lien Collateral to the Aimco Agent pursuant to the Aimco Loan Documents, together with a notice instructing the Aimco Agent to deliver any such Guarantor Collateral constituting First Lien Collateral to the Collateral Agent, shall satisfy any delivery requirement hereunder.
