          (f) Except as specifically set forth in Sections 3.1(a) and (d) and Section 4, nothing in this Agreement shall prohibit the receipt by the Second Lien Secured Party or any Second Lien Claimholders of the required payments of Murabaha Price, Agreed Profit and other amounts owed in respect of the Second Lien Obligations so long as such receipt is not the direct or indirect result of the exercise by the Second Lien Secured Party or any Second Lien Claimholders of rights or remedies as a secured creditor (including set-off) or enforcement in contravention of this Agreement of any Lien held by any of them. Nothing in this Agreement impairs or otherwise adversely affects any rights or remedies the First Lien Secured Party or the First Lien Claimholders may have with respect to the First Lien Collateral.

     3.2 Actions Upon Breach. If any Second Lien Claimholder, in contravention of the terms of this Agreement, in any way takes, attempts to or threatens to take any action with respect to the Collateral (including any attempt to realize upon or enforce any remedy with respect to this Agreement), or fails to take any action required by this Agreement, this Agreement shall create an irrebutable presumption and admission by such Second Lien Claimholder that relief against such Second Lien Claimholder by injunction, specific performance and/or other appropriate equitable relief is necessary to prevent irreparable harm to the First Lien Claimholders, it being understood and agreed by the Second Lien Secured Party on behalf of each Second Lien Claimholder that (i) the First Lien Claimholders’ damages from its actions may at that time be difficult to ascertain and may be irreparable, and (ii) each Second Lien Claimholder waives any defense that the First Lien Claimholders cannot demonstrate damage and/or be made whole by the awarding of damages.

     SECTION 4. Payments.

     4.1 Application of Proceeds. So long as the Discharge of First Lien Obligations has not occurred, whether or not any Insolvency or Liquidation Proceeding has been commenced by or against Tensar or any other Grantor, any Collateral or proceeds thereof received in connection with the sale or other disposition of, or collection on, such Collateral upon the exercise of remedies shall be applied by the First Lien Secured Party to the First Lien Obligations then due and owing in such order as specified in the relevant First Lien Lease/Purchase Facilities Documents. Upon the Discharge of the First Lien Obligations, the First Lien Secured Party shall deliver to the Second Lien Secured Party any Collateral and proceeds of Collateral held by it in the same form as received, with any necessary endorsements or as a court of competent jurisdiction may otherwise direct to be applied by the Second Lien Secured Party to the Second Lien Obligations.

     4.2 Payments Over. So long as the Discharge of First Lien Obligations has not occurred, whether or not any Insolvency or Liquidation Proceeding has been commenced by or against Tensar or any other Grantor, any Collateral or proceeds thereof (together with assets or proceeds subject to Liens referred to in the final sentence of

Section 2.3) received by the Second Lien Secured Party or any Second Lien Claimholders in connection with the exercise of any right or remedy (including set-off or recoupment) relating to the Collateral in contravention of this Agreement shall be segregated and held in trust and forthwith paid over to the First Lien Secured Party for the benefit of the First Lien Claimholders in the same form as received, with any necessary endorsements or as a court of competent jurisdiction may otherwise direct. The First Lien Secured Party is hereby authorized to make any such endorsements as agent for the Second Lien Secured Party or any such Second Lien Claimholders. This authorization is coupled with an interest and is irrevocable until the Discharge of First Lien Obligations. So long as the Discharge of First Lien Obligations has not occurred, if in any Insolvency or Liquidation Proceeding the Second Lien Secured Party or any Second Lien Claimholders shall receive any distribution of money or other property in respect of the Collateral, such money or other property shall be segregated and held in trust and forthwith paid over to the First Lien Secured Party for the benefit of the First Lien Claimholders in the same form as received, with any necessary endorsements. Any Lien received by the Second Lien Secured Party or any Second Lien Claimholders in any Insolvency or Liquidation Proceeding shall be subject to the terms of this Agreement.

     4.3 Certain Agreements with respect to Unenforceable Collateral. In addition to the rights and obligations of the First Lien Secured Party, the Second Lien Secured Party, the First Lien Claimholders and Second Lien Claimholders set forth herein, in the event that in any Insolvency or Liquidation Proceeding a determination is made that Liens encumbering any Collateral are not enforceable for any reason, then the Second Lien Secured Party and the Second Lien Claimholders agree that any distribution or recovery they may receive with respect to, or allocable to, the value of such Collateral or any proceeds thereof shall (for so long as the Discharge of the First Lien Obligations has not occurred) be segregated and held in trust and forthwith paid over to the First Lien Secured Party for the benefit of the First Lien Claimholders in the same form as received without recourse, representation or warranty (other than a representation of the Second Lien Secured Party that it has not otherwise sold, assigned, transferred or pledged any right, title or interest in and to such distribution or recovery) but with any necessary endorsements or as a court of competent jurisdiction may otherwise direct until such time as the Discharge of First Lien Obligations has occurred. The First Lien Secured Party is hereby authorized to make any such endorsements as agent for the Second Lien Secured Party and any such Second Lien Claimholders. This authorization is coupled with an interest and is irrevocable.

     SECTION 5. Other Agreements.

     5.1 Releases.

          (a) If in connection with any sale, lease, exchange, transfer or other disposition of any Collateral (collectively, a “Disposition”) occurring in connection with the exercise of the First Lien Secured Party’s rights and remedies in respect of the Collateral, the First Lien Secured Party, for itself or on behalf of any of the First Lien Claimholders, releases any of its Liens on any part of the Collateral, then the Liens, if any, of the Second Lien Secured Party, for itself or for the benefit of the Second Lien

Claimholders, on such Collateral shall be automatically, unconditionally and simultaneously released; provided that such exercise is taken in good faith and the Liens of the Second Lien Claimholders attach to the proceeds thereof, subject to the provisions of Section 2 and 4 hereof. The Second Lien Secured Party for itself or on behalf of any such Second Lien Claimholders, promptly shall execute and deliver to the First Lien Agent or such Guarantor Subsidiary such termination statements, releases and other documents as the First Lien Secured Party or such Guarantor Subsidiary may request to effectively confirm such release.

          (b) Subject to Section 5.1(e), if in connection with any Disposition permitted under the terms of both the First Lien Lease/Purchase Facilities Documents and the Second Lien Commodities Purchase Facility Documents (other than in connection with the exercise of the First Lien Secured Party’s rights and remedies in respect of the Collateral provided for in Section 3.1), the First Lien Secured Party, for itself or on behalf of any of the First Lien Claimholders, releases any of its Liens on any part of the Collateral, other than (A) in connection with the Discharge of First Lien Obligations and (B) after the occurrence and during the continuance of any Event of Default under the Second Lien Commodities Purchase Agreement, then the Liens, if any, of the Second Lien Secured Party, for itself or for the benefit of the Second Lien Claimholders, on such Collateral shall be released simultaneously upon notice of such Disposition to the Second Lien Secured Party and the Second Lien Agent. The Second Lien Secured Party, for itself or on behalf of any such Second Lien Claimholders, promptly shall execute and deliver to the First Lien Secured Party or such Guarantor Subsidiary such termination statements, releases and other documents as the First Lien Secured Party or such Grantor may request to effectively confirm such release; provided, however, that any such release shall not be effective until such Disposition is consummated and shall not extend to the proceeds thereof. For avoidance of doubt, the exercise of the First Lien Secured Party’s remedies in respect of the Collateral shall not constitute a Disposition but instead shall be governed by Section 5.1(a) above.

          (c) Until the Discharge of First Lien Obligations occurs, the Second Lien Secured Party, for itself and on behalf of the Second Lien Claimholders, hereby irrevocably constitutes and appoints the First Lien Secured Party and any officer or agent of the First Lien Secured Party, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Second Lien Secured Party or such holder or in the First Lien Secured Party’s own name, from time to time in the First Lien Secured Party’s discretion, for the purpose of carrying out the terms of this Section 5.1, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary to accomplish the purposes of this Section 5.1, including any endorsements or other instruments of transfer or release.

          (d) Until the Discharge of First Lien Obligations occurs, to the extent that the First Lien Secured Party or the First Lien Claimholders (i) have released any Lien on Collateral or any Guarantor Subsidiary from its obligation under its guaranty and any such Liens or guaranty are later reinstated or (ii) obtain any new liens or additional guarantees from any Guarantor Subsidiary, then the Second Lien Secured

Party, for itself and for the Second Lien Claimholders, shall be granted a Lien on any such Collateral, subject to the lien subordination provisions of this Agreement, and an additional guaranty, as the case may be.

          (e) In the event that the stated amount of funded First Lien Obligations plus the aggregate stated amount of unused commitments under the Commodities Purchase Agreement (collectively, the “First Lien Obligations Amount”), at any date of determination no longer constitute at least 25% of the sum of (i) the First Lien Obligations Amount and (ii) the stated amount of funded Second Lien Obligations (collectively, the “Second Lien Obligations Amount”), then any release provided for in Section 5.1(b) above (except for releases given in connection with a Disposition permitted under the First Lien Lease/Purchase Facilities Documents and the Second Lien Commodities Purchase Facility Documents) shall require the consent of (i) First Lien Claimholders representing in the aggregate more than 50% of the First Lien Obligations Amount and (ii) the Second Lien Agent.

     5.2 Insurance. Unless and until the Discharge of First Lien Obligations has occurred, the First Lien Secured Party and the First Lien Claimholders shall have the sole and exclusive right, subject to the rights of the Grantor under the First Lien Lease/Purchase Facilities Documents, to adjust settlement for any insurance policy covering the Collateral in the event of any loss thereunder and to approve any award granted in any condemnation or similar proceeding (or any deed in lieu of condemnation) affecting the Collateral. Unless and until the Discharge of First Lien Obligations has occurred, and subject to the rights of the Grantors under the First Lien Lease/Purchase Facilities Documents, all proceeds of any such policy and any such award (or any payments with respect to a deed in lieu of condemnation) if in respect of the Collateral shall be paid to the First Lien Secured Party for the benefit of the First Lien Claimholders pursuant to the terms of the First Lien Lease/Purchase Facilities Documents (including for purposes of cash collateralization of letters of credit) and thereafter, to the extent no First Lien Obligations are outstanding, and subject to the rights of the Grantors under the Second Lien Commodities Purchase Facility Documents, to the Second Lien Secured Party for the benefit of the Second Lien Claimholders to the extent required under the Second Lien Security Documents and then, to the extent no Second Lien Obligations are outstanding, to the owner of the subject property, such other Person as may be entitled thereto or as a court of competent jurisdiction may otherwise direct. Until the Discharge of First Lien Obligations has occurred, if the Second Lien Secured Party or any Second Lien Claimholders shall, at any time, receive any proceeds of any such insurance policy or any such award or payment in contravention of this Agreement, it shall pay such proceeds over to the First Lien Secured Party in accordance with the terms of Section 4.2.

     5.3 Amendments to First Lien Lease/Purchase Facilities Documents and Second Lien Commodities Purchase Facility Documents.

          (a) The First Lien Lease/Purchase Facilities Documents may be amended, supplemented or otherwise modified in accordance with their terms and the First Lien Lease/Purchase Agreements may be Refinanced, in each case, without notice to, or the consent of, the Second Lien Secured Party or the Second Lien Claimholders, all

without affecting the lien subordination or other provisions of this Agreement; provided, however, that (x) the holders of such Refinancing debt bind themselves to the terms of this Agreement in a writing addressed to the Second Lien Secured Party and the Second Lien Claimholders and (y) any such amendment, supplement, modification or Refinancing shall not:

          (i) contravene the provisions of this Agreement;

          (ii) increase the sum of the then outstanding aggregate stated amount of Acquisition Cost and Purchase Price under the First Lien Lease/Purchase Agreements plus any unused portion of commitments under the Commodities Purchase Agreement in excess of $ 182,000,000 less any payments in respect of Acquisition Cost and/or permanent reductions in commitment with respect to the Commodities Purchase Agreement, in each case, under the First Lien Lease/Purchase Agreements (the “Cap Amount”);

          (iii) increase the “Rental Rate”, “Agreed Profit” or similar component of rent or profit by more than 3.00% per annum (excluding increases resulting from the accrual of rent or profit at the default rate);

          (iv) permit the release of liens on Collateral in a manner not contemplated by the First Lien Lease/Purchase Facilities Documents;

          (v) extend the scheduled maturity of the Lease Agreement, the Commodities Purchase Agreement or any Refinancing thereof beyond the scheduled maturity of the Second Lien Commodities Purchase Agreement or any permitted Refinancing thereof;

          (vi) modify (or have the effect of a modification of) the mandatory prepayment provisions of the Lease Agreement or the Commodities Purchase Agreement in a manner adverse to the holders of Second Lien Obligations; or

          (vii) result in the First Lien Secured Party being a different Person than the Second Lien Secured Party.

          (b) The Second Lien Commodities Purchase Facility Documents may be amended, supplemented or otherwise modified in accordance with their terms and the Second Lien Commodities Purchase Agreement may be Refinanced, in each case, without notice to, or the consent of, the First Lien Agent or the First Lien Claimholders, all without affecting the lien subordination or other provisions of this Agreement; provided, however, that (x) the holders of such Refinancing debt bind themselves to the terms of this Agreement in a writing addressed to the First Lien Agent and the First Lien Claimholders and (y) any such amendment, supplement, modification or Refinancing shall not:

          (i) contravene the provisions of this Agreement;

          (ii) increase the then outstanding stated amount of the aggregate outstanding Purchase Price under the Second Lien Commodities Purchase Facility;

          (iii) increase the “Agreed Profit” or similar component of profit under the Second Lien Commodities Purchase Facility by more than 3.00% per annum (excluding increases resulting from the accrual of rent or profit at the default rate);

          (iv) change (to earlier dates) any dates upon which payments of Purchase Price or Agreed Profit, each case, under the Second Lien Commodities Purchase Facility are due thereon;

          (v) change any default or Event of Default thereunder in a manner adverse to the Tensar Parties thereunder;

          (vi) change the redemption, prepayment or defeasance provisions thereof (except in order to duplicate any amendments, supplements or other modifications to the First Lien Lease/Purchase Facilities Documents);

          (vii) change any collateral therefor (other than to release such collateral and to duplicate any amendments, supplements or other modifications to the First Lien :Lease/Purchase Facilities Documents); or

          (viii) result in the First Lien Secured Party being a different Person than the Second Lien Secured Party.

          (ix) increase the obligations of the Tensar Parties thereunder or confer any additional rights on the holders of Second Lien Obligations which would be adverse to the holders of First Lien Obligations.

           The Second Lien Obligations may only be Refinanced

               (1) if the terms and conditions of such Refinancing are no less favorable in the aggregate to the Tensar Parties and to the First Lien Claimholders than the terms and conditions of the Second Lien Commodities Purchase Agreement (as determined in the reasonable opinion of the First Lien Secured Party, acting on behalf of itself and the other First Lien Claimholders),

               (2) if the outstanding aggregate stated amount of the aggregate outstanding Purchase Price thereunder is not increased and the average life to maturity thereof is greater than or equal to that of the Purchase Price under the Second Lien Commodities Purchase Agreement, and

               (3) if all other terms and provisions of such Refinancing are reasonably acceptable to the First Lien Secured

Party, the Second Lien Secured Party is the same Person as the First Lien Secured Party and any other holder of Second Lien Obligations binds themselves in a writing addressed to the First Lien Secured Party and the First Lien Claimholders to the terms of this Agreement.

          (c) Each of Tensar Holdings and Tensar agree that each Second Lien Security Document shall include the following language (or language to similar effect approved by the First Lien Secured Party):

“Notwithstanding anything herein to the contrary, the lien and security interest granted to the Second Lien Secured Party pursuant to this Agreement and the exercise of any right or remedy by the Second Lien Secured Party hereunder are subject to the provisions of the Tensar Intercreditor Agreement, dated as of October 31, 2005 (as amended, restated, supplemented or otherwise modified from time to time, the “Intercreditor Agreement”), among Tensar Holdings, Inc., The Tensar Corporation LLC, TCO Funding Corp., Credit Suisse, as First Lien Agent, and American Capital Financial Services, Inc., as Second Lien Agent, and certain other Persons party or that may become party thereto from time to time. In the event of any conflict between the terms of the Intercreditor Agreement and this Agreement, the terms of the Intercreditor Agreement shall govern and control.”

          (d) In the event that the First Lien Secured Party or any First Lien Claimholders and the relevant Grantor enter into any amendment, waiver or consent in respect of any of the First Lien Security Documents for the purpose of adding to, or deleting from, or waiving or consenting to any departures from any provisions of, any First Lien Security Document or changing in any manner the rights of the First Lien Secured Party, such First Lien Claimholders, Tensar or any other Grantor thereunder, then such amendment, waiver or consent shall apply automatically to any comparable provision of the Comparable Second Lien Security Document without the consent of the Second Lien Secured Party or the Second Lien Claimholders and without any action by the Second Lien Secured Party, Tensar or any other Grantor, provided that:

          (i) no such amendment, waiver or consent shall have the effect of: (A) removing or releasing assets subject to the Lien of the Second Lien Security Documents, except to the extent that a release of such Lien is permitted or required by Section 5.1 and provided that there is a corresponding release of such Lien securing the First Lien Obligations; (B) imposing duties on the Second Lien Secured Party without its consent; (C) permitting other Liens on the Collateral not permitted under the terms of the Second Lien Commodities Purchase Facilities Documents or Section 6; or (D) being prejudicial to the interests of the Second Lien Claimholders to a greater extent than the First Lien Claimholders; and

          (ii) notice of such amendment, waiver or consent shall have been given to the Second Lien Claimholders and the Second Lien Secured

Party within ten Business Days after the Effective Date of such amendment, waiver or consent.

          (e) Notwithstanding the foregoing provisions of this Section 5.3, amendments, waivers, consents, supplements and other modifications to or in respect of this Agreement shall be governed by Section 8.3.

     5.4 Bailee for Perfection.

          (a) The First Lien Secured Party agrees to hold that part of the Collateral that is in its possession or control (or in the possession or control of its agents or bailees) to the extent that possession or control thereof is taken to perfect a Lien thereon under the UCC (such Collateral being the “Pledged Collateral”) as collateral agent for the First Lien Claimholders and as bailee on behalf of or for the benefit of the Second Lien Secured Party (such bailment being intended, among other things, to satisfy the requirements of Sections 8-106(d)(3), 8-301(a)(2) and 9-313(c) of the UCC) and any assignee solely for the purpose of perfecting by possession or delivery the security interest granted under the First Lien Lease/Purchase Facilities Documents and the Second Lien Commodities Purchase Facilities Documents, respectively, subject to the terms and conditions of this Section 5.4.

          (b) The First Lien Secured Party shall have no obligation whatsoever to the First Lien Claimholders, the Second Lien Secured Party or any Second Lien Claimholder to ensure that the Pledged Collateral is genuine or owned by any of the Grantors or to preserve rights or benefits of any Person except as expressly set forth in this Section 5.4. The duties or responsibilities of the First Lien Secured Party under this Section 5.4 shall be limited solely to holding the Pledged Collateral as bailee in accordance with this Section 5.4 and delivering the Pledged Collateral upon a Discharge of First Lien Obligations as provided in paragraph (d) below.

          (c) The First Lien Secured Party acting pursuant to this Section 5.4 shall not have by reason of the First Lien Security Documents, the Second Lien Security Documents, this Agreement or any other document a fiduciary relationship in respect of any Tensar Party, the First Lien Claimholders, the Second Lien Secured Party or any Second Lien Claimholder.

          (d) Upon the Discharge of First Lien Obligations, the First Lien Secured Party shall deliver the remaining Pledged Collateral (if any) together with any necessary endorsements, first, to the Second Lien Secured Party to the extent Second Lien Obligations remain outstanding, and second, to Tensar or any other applicable Grantor to the extent no First Lien Obligations or Second Lien Obligations remain outstanding (in each case, so as to allow such Person to obtain possession or control of such Pledged Collateral). The First Lien Secured Party further agrees in such circumstances to take all other action reasonably requested by the Second Lien Secured Party in connection with the Second Lien Secured Party obtaining a first-priority interest in the Collateral or as a court of competent jurisdiction may otherwise direct.

     5.5 When Discharge of First Lien Obligations Deemed to Not Have Occurred. If, at any time after the Discharge of First Lien Obligations has occurred, but prior to the expiration of 10 Business Days after the consummation of such discharge, Tensar or any Grantor enters into any Refinancing of any First Lien Lease/Purchase Facilities Document evidencing a First Lien Obligation which Refinancing is permitted pursuant to Section 5.3(a)(ii) and 5.3(a)(v), then such Discharge of First Lien Obligations shall automatically be deemed not to have occurred for all purposes of this Agreement (other than with respect to any actions taken as a result of the occurrence of such first Discharge of First Lien Obligations), and, from and after the date on which written notice thereof is delivered to the Second Lien Secured Party in, the obligations under such Refinancing of the First Lien Lease/Purchase Facilities Document shall automatically be treated as First Lien Obligations for all purposes of this Agreement, including for purposes of the Lien priorities and rights in respect of Collateral set forth herein. If the new First Lien Obligations under the new First Lien Lease/Purchase Facilities Documents are secured by assets of any Tensar Party that do not also secure the Second Lien Obligations, then the Second Lien Obligations shall be secured at such time by a second priority Lien on such assets to the same extent provided in the Second Lien Security Documents and this Agreement.

     SECTION 6. Insolvency or Liquidation Proceedings.

     6.1 Finance and Sale Issues. Until the Discharge of First Lien Obligations has occurred, if Tensar or any other Grantor shall be subject to any Insolvency or Liquidation Proceeding and the First Lien Secured Party shall desire to permit the use of “Cash Collateral” (as such term is defined in Section 363(a) of the Bankruptcy Code), on which the First Lien Secured Party or any other creditor has a Lien or to permit Tensar or any other Grantor to obtain financing, whether from the First Lien Claimholders or any other Person under Section 364 of the Bankruptcy Code or any similar Bankruptcy Law (“DIP Financing”), then the Second Lien Secured Party, on behalf of itself and the Second Lien Claimholders, agrees that it will raise no objection to such Cash Collateral use or DIP Financing on commercially reasonable terms and to the extent the Liens securing the First Lien Obligations are subordinated to or pari passu with such DIP Financing, the Second Lien Secured Party will subordinate its Liens in the Collateral to the Liens securing such DIP Financing (and all Obligations relating thereto) and will not request adequate protection or any other relief in connection therewith (except, as expressly agreed by the First Lien Secured Party or to the extent permitted by Section 6.3); provided that the sum of the aggregate principal amount of such DIP Financing plus the aggregate outstanding stated amount of Acquisition Cost and Purchase Price outstanding under the First Lien Lease/Purchase Agreements and the other First Lien Lease/Purchase Facilities Documents (the “Outstanding Amount”) does not exceed the sum of $15.0 million plus the lesser of (x) the Cap Amount and (y) the Outstanding Amount; and provided further that the Second Lien Secured Party and the Second Lien Claimholders retain the right to object to any ancillary agreements or arrangements regarding Cash Collateral use or the DIP Financing that are materially prejudicial to their interests. The Second Lien Secured Party, on behalf of the Second Lien Claimholders, agrees that it will not raise any objection or oppose a motion to sell or otherwise dispose of any Collateral free and clear of its Liens or other claims under

Section 363 of the Bankruptcy Code if the requisite First Lien Claimholders have consented to such sale or disposition of such assets, such motion does not impair the rights of the Second Lien Claimholders under Section 363(k) of the Bankruptcy Code, and the proceeds thereof are applied in accordance with Sections 2 and 4.

     6.2 Relief from the Automatic Stay. Until the Discharge of First Lien Obligations has occurred, the Second Lien Secured Party, on behalf of itself and the Second Lien Claimholders, agrees that none of them shall seek (or support any other Person seeking) relief from the automatic stay or any other stay in any Insolvency or Liquidation Proceeding in respect of the Collateral without the prior written consent of the First Lien Secured Party, unless a motion for adequate protection permitted under Section 6.3 has been denied by the Bankruptcy Court.

     6.3 Adequate Protection.

          (a) The Second Lien Secured Party, on behalf of itself and the Second Lien Claimholders, agrees that none of them shall contest (or support any other Person contesting):

          (i) any request by the First Lien Secured Party or the First Lien Claimholders for adequate protection; or

          (ii) any objection by the First Lien Secured Party or the First Lien Claimholders to any motion, relief, action or proceeding based on the First Lien Secured Party or the First Lien Claimholders claiming a lack of adequate protection.

          (b) Notwithstanding the foregoing provisions in this Section 6.3, in any Insolvency or Liquidation Proceeding:

          (i) if the First Lien Claimholders (or any subset thereof) are granted adequate protection in the form of additional collateral in connection with any Cash Collateral use or DIP Financing, then the Second Lien Secured Party, on behalf of itself or any of the Second Lien Claimholders, may seek or request adequate protection solely in the form of a Lien on such additional collateral or in the form of a superpriority claim, which Lien and claim will be subordinated to the Liens securing the First Lien Obligations and such Cash Collateral use or DIP Financing (and all Obligations relating thereto) on the same basis as the other Liens securing the Second Lien Obligations are so subordinated to the Liens securing the First Lien Obligations under this Agreement; and

          (ii) in the event the Second Lien Secured Party, on behalf of itself or any of the Second Lien Claimholders, seeks or requests adequate protection in respect of the Second Lien Obligations and such adequate protection is granted in the form of additional collateral, then the Second Lien Secured Party, on behalf of itself or any of the Second Lien Claimholders, agrees that the First Lien Secured Party shall also be granted a senior Lien on such additional collateral as security for the First Lien Obligations and for any Cash

Collateral use or DIP Financing provided by the First Lien Claimholders and that any Lien on such additional collateral securing the Second Lien Obligations shall be subordinated to the Lien on such collateral securing the First Lien Obligations and any such DIP Financing provided by the First Lien Claimholders (and all Obligations relating thereto) and to any other Liens granted to the First Lien Claimholders as adequate protection on the same basis as the other Liens securing the Second Lien Obligations are so subordinated to such First Lien Obligations under this Agreement. Except as otherwise expressly set forth in Section 6.1 or in connection with the exercise of remedies with respect to the Collateral, nothing herein shall limit the rights of the Second Lien Secured Party or the Second Lien Claimholders from seeking adequate protection with respect to their rights in the Collateral in any Insolvency or Liquidation Proceeding (including adequate protection in the form of a cash payment, periodic cash payments, cash payments of interest or otherwise). Neither the First Lien Secured Party nor any First Lien Claimholder shall contest or object to any request by the Second Lien Secured Party on behalf of the Second Lien Claimholders for adequate protection or any objection by the Second Lien Secured Party on behalf of the Second Lien Claimholders to any motion or action in a proceeding claiming a lack of adequate protection so long as the requested adequate protection is in compliance with the terms set forth above.

     6.4 No Waiver. Subject to Sections 3.1(a) and (d) and the last sentence of Section 6.3(b)(ii), nothing contained herein shall prohibit or in any way limit the First Lien Secured Party or any First Lien Claimholder from objecting in any Insolvency or Liquidation Proceeding or otherwise to any action taken by the Second Lien Secured Party or any of the Second Lien Claimholders, including the seeking by the Second Lien Secured Party or any Second Lien Claimholders of adequate protection or the asserting by the Second Lien Secured Party or any Second Lien Claimholders of any of its rights and remedies under the Second Lien Commodities Purchase Facility Documents or otherwise. Except as expressly set forth in this Agreement neither the Second Lien Agent nor any Second Lien Claimholder shall be prohibited or limited from objecting in any Insolvency or Liquidation Proceeding or otherwise to any action taken by the First Lien Administrative Agent or any of the First Lien Claimholders.

     6.5 Avoidance Issues. If any First Lien Claimholder is required in any Insolvency or Liquidation Proceeding or otherwise to turn over or otherwise pay to the estate of any Tensar Party any amount paid in respect of First Lien Obligations (a “Recovery”), then such First Lien Claimholders shall be entitled to a reinstatement of First Lien Obligations with respect to all such recovered amounts. If this Agreement shall have been terminated prior to such Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise affect the obligations of the parties hereto from such date of reinstatement.

     6.6 Reorganization Securities. If, in any Insolvency or Liquidation Proceeding, debt obligations of the reorganized debtor secured by Liens upon any property of the reorganized debtor are distributed pursuant to a plan of reorganization or

similar dispositive restructuring plan, both on account of First Lien Obligations and on account of Second Lien Obligations, then, to the extent the debt obligations distributed on account of the First Lien Obligations and on account of the Second Lien Obligations are secured by Liens upon the same property, the provisions of this Agreement will survive the distribution of such debt obligations pursuant to such plan and will apply with like effect to the Liens securing such debt obligations.

     6.7 Post-Petition Charges.

          (a) Neither the Second Lien Secured Party nor any Second Lien Claimholder shall oppose or seek to challenge any claim by the First Lien Secured Party or any First Lien Claimholder for allowance in any Insolvency or Liquidation Proceeding of First Lien Obligations consisting of Post-Petition Charges to the extent of the value of any First Lien Claimholder’s Lien, without regard to the existence of the Lien of the Second Lien Secured Party on behalf of the Second Lien Claimholders on the Collateral.

          (b) Neither the First Lien Secured Party nor any other First Lien Claimholder shall oppose or seek to challenge any claim by the Second Lien Secured Party or any Second Lien Claimholder for allowance in any Insolvency or Liquidation Proceeding of Second Lien Obligations consisting of Post-Petition Charges to the extent of the value of the Lien of the Second Lien Secured Party on behalf of the Second Lien Claimholders on the Collateral (after taking into account the First Lien Collateral).

     6.8 Waiver. The Second Lien Secured Party, for itself and on behalf of the Second Lien Claimholders, waives any claim it may hereafter have against any First Lien Claimholder arising out of the election of any First Lien Claimholder of the application of Section 1111(b)(2) of the Bankruptcy Code, and/or out of any cash collateral or financing arrangement or out of any grant of a security interest in connection with the Collateral in any Insolvency or Liquidation Proceeding. The First Lien Agent, for itself and on behalf of the First Lien Claimholders, waives any claim it may hereafter have against any Second Lien Claimholder arising out of the election of any Second Lien Claimholder of the application of Section 1111(b)(2) of the Bankruptcy Code, and/or out of any cash collateral or financing arrangement or out of any grant of a security interest in connection with the Collateral in any Insolvency or Liquidation Proceeding.

     6.9 Separate Grants of Security and Separate Classification. The Second Lien Secured Party, for itself and on behalf of the Second Lien Claimholders, and the First Lien Secured Party, for itself and on behalf of the First Lien Claimholders, acknowledge and agree that:

          (a) the grants of Liens pursuant to the First Lien Security Documents and the Second Lien Security Documents constitute two separate and distinct grants of Liens; and

          (b) because of, among other things, their differing rights in the Collateral, the Second Lien Obligations are fundamentally different from the First Lien

Obligations and must be separately classified in any plan of reorganization proposed or adopted in an Insolvency or Liquidation Proceeding.

To further effectuate the intent of the parties as provided in the immediately preceding sentence, if it is held that the claims of the First Lien Claimholders and the Second Lien Claimholders in respect of the Collateral constitute only one secured claim (rather than separate classes of senior and junior secured claims), then each of the parties hereto hereby acknowledges and agrees that, (x) subject to Sections 2.1 and 4.1, all distributions shall be made as if there were separate classes of senior and junior secured claims against the Grantors in respect of the Collateral (with the effect being that, to the extent that the aggregate value of the Collateral exceeds the First Lien Obligations (for this purpose ignoring all claims held by the Second Lien Claimholders), the First Lien Claimholders shall be entitled to receive, in addition to amounts distributed to them in respect of Acquisition Cost, Purchase Price, principal, pre-petition interest and other claims, all amounts owing in respect of Post-Petition Charges, including any additional interest payable pursuant to the First Lien Credit Agreement, arising from or related to a default, which is disallowed as a claim in any Insolvency or Liquidation Proceeding) before any distribution is made in respect of the claims held by the Second Lien Claimholders with the Second Lien Secured Party, for itself and on behalf of the Second Lien Claimholders, and (y) the Second Lien Agent and the Second Lien Claimholders shall turn over to the First Lien Secured Party, for itself and on behalf of the First Lien Claimholders, amounts otherwise received or receivable by them to the extent necessary to effectuate the intent of this sentence, even if such turnover has the effect of reducing the claim or recovery of the Second Lien Claimholders).
