Delivery of an executed counterpart of a signature page to this Amendment by facsimile shall be effective as delivery of a manually executed counterpart of this Amendment, as the case may be.

9. Severability. Any provision of this Amendment that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Annex B

SECTION 2. GUARANTEE

2.1. Guarantee.

(a) Each of the Guarantors (other than Tensar) hereby, jointly and severally, unconditionally and irrevocably, guarantees to TCO, for the ratable benefit of the Secured Parties and their respective successors, indorsees, transferees and assigns, the prompt and complete payment and performance by Tensar when due (whether at the stated maturity, by acceleration or otherwise) of Tensar’s Obligations. Each of the Guarantors hereby, jointly and severally, unconditionally and irrevocably, guarantees to TCO, for the ratable benefit of the Secured Parties and their respective successors, indorsees, transferees and assigns, the prompt and complete payment and performance by Luxco when due (whether at the stated maturity, by acceleration or otherwise) of Luxco’s Obligations.

(b) If and to the extent required in order for the Obligations of any Guarantor to be enforceable under applicable federal, state and other laws relating to the insolvency of debtors, the maximum liability of such Guarantor hereunder shall be limited to the greatest amount which can lawfully be so guaranteed by such Guarantor under such laws, after giving effect to any rights of contribution, reimbursement and subrogation arising under Section 2.2. Each Guarantor acknowledges and agrees that, to the extent not prohibited by applicable law, (i) such Guarantor (as opposed to its creditors, representatives of creditors or bankruptcy trustee, including such Guarantor in its capacity as debtor in possession exercising any powers of a bankruptcy trustee) has no personal right under such laws to reduce, or request any judicial relief that has the effect of reducing, the amount of its liability under this Agreement, (ii) such Guarantor (as opposed to its creditors, representatives of creditors or bankruptcy trustee, including such Guarantor in its capacity as debtor in possession exercising any powers of a bankruptcy trustee) has no personal right to enforce the limitation set forth in this Section 2.1 (b) or to reduce, or request judicial relief reducing, the amount of its liability under this Agreement, and (iii) the limitation set forth in this Section 2.l (b) may be enforced only to the extent required under such laws in order for the obligations of such Guarantor under this Agreement to be enforceable under such laws and only by or for the benefit of a creditor, representative of creditors or bankruptcy trustee of such Guarantor or other person entitled, under such laws, to enforce the provisions thereof.

(c) Each Guarantor (other than Tensar) agrees that the Obligations of Tensar may at any time and from time to time be incurred or permitted in an amount exceeding the maximum liability of such Guarantor under Section 2.1 (b) without impairing the guarantee contained in this Section 2 or affecting the rights and remedies of any Secured Party hereunder and each Guarantor agrees that the Obligations of Luxco may at any time and from time to time be incurred or permitted in an amount exceeding the maximum liability of such Guarantor under Section 2.1 (b) without impairing the guarantee contained in this Section 2 or affecting the rights and remedies of any Secured Party hereunder.

(d) The guarantee contained in this Section 2 shall remain in full force and effect until payment in full of the Obligations, notwithstanding that from time to time during the

term of the Lease/Purchase Facilities Documents, Tensar may be free from any of its Obligations and Luxco may be from any of its Obligations.

(e) No payment made by Tensar, Luxco, any of the Guarantors, any other guarantor or any other person or received or collected by any Secured Party from Tensar, Luxco, any of the Guarantors, any other guarantor or any other person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations of Tensar or the Obligations of Luxco shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding any such payment (other than, with respect to any Tensar Obligations, any payment made by such Guarantor in respect of Tensar’s Obligations or any payment received or collected from such Guarantor in respect of Tensar’s Obligations and, with respect to any Luxco Obligations, any payment made by such Guarantor in respect of Luxco’s Obligations or any payment received or collected from such Guarantor in respect of Luxco’s Obligations), remain liable for Tensar’s Obligations and Luxco’s Obligations up to the maximum liability of such Guarantor hereunder until the Obligations of Tensar and the Obligations of Luxco are paid in full and all of the Lease/Purchase Facilities Documents (and any commitments to lease property or to engage in commodities transactions thereunder and any letters of credit or other Guarantee Obligations referred to therein) shall have been terminated or have expired.

2.2. Rights of Reimbursement, Contribution and Subrogation. In case any payment is made on account of the Obligations by any Grantor or is received or collected on account of the Obligations from any Grantor or its property:

(a) If such payment is made by Tensar (with respect to Obligations other than its Guarantor Obligations) or from its property, then, if and to the extent such payment is made on account of Obligations arising from or relating to any Lease/Purchase Facility Document, Tensar shall not be entitled, other than in accordance with the terms of this Agreement (i) to demand or enforce reimbursement or contribution in respect of such payment from any other Grantor or (ii) to be subrogated to any claim, interest, right or remedy of any Secured Party against any other person, including any other Grantor or its property.

(b) If such payment is made by a Guarantor or from its property, such Guarantor shall be entitled, subject to and upon payment in full of all of the Obligations, (i) to demand and enforce reimbursement for the full amount of such payment from Tensar or Luxco (as the case may be) and (ii) to demand and enforce contribution in respect of such payment from each other Guarantor that has not paid its fair share of such payment, as necessary to ensure that (after giving effect to any enforcement of reimbursement rights provided hereby) each Guarantor pays its fair share of the unreimbursed portion of such payment. For this purpose, the fair share of each Guarantor as to any unreimbursed payment shall be determined based on an equitable apportionment of such unreimbursed payment among all Guarantors based on the relative value of their assets and any other equitable considerations deemed appropriate by a court of competent jurisdiction.

(c) If and whenever (after payment in full of the Obligations) any right of reimbursement or contribution becomes enforceable by any Grantor against any other Grantor under Sections 2.2(a) and 2.2(b), such Grantor shall be entitled, subject to and upon payment in

full of all of the Obligations, to be subrogated (equally and ratably with all other Grantors entitled to reimbursement or contribution from any other Grantor as set forth in this Section 2.2) to any security interest that may then be held by TCO upon any Collateral granted to it in this Agreement. Such right of subrogation shall be enforceable solely against the Grantors, and not against the Secured Parties, and neither TCO nor any other Secured Party shall have any duty whatsoever to warrant, ensure or protect any such right of subrogation or to obtain, perfect, maintain, hold, enforce or retain any Collateral for any purpose related to any such right of subrogation. If subrogation is demanded by any Grantor, then (after payment in full of all of Obligations) TCO shall deliver to the Grantors making such demand, or to a representative of such Grantors or of the Grantors generally, an instrument satisfactory to TCO and the Administrative Agent transferring, on a quitclaim basis without any recourse, representation, warranty or obligation whatsoever, whatever security interest TCO then may hold in whatever Collateral may then exist that was not previously released or disposed of by TCO.

(d) All rights and claims arising under this Section 2.2 or based upon or relating to any other right of reimbursement, indemnification, contribution or subrogation may at any time arise or exist in favor of any Grantor as to any payment on account of the Obligations made by it or received or collected from its property shall be fully subordinated in all respects to the prior payment in full of all of the Obligations. Until payment in full of all of Obligations, no Grantor shall demand or receive any collateral security, payment or distribution whatsoever (whether in cash, property or securities or otherwise) on account of any such right or claim. If any such payment or distribution is made or becomes available to any Grantor in any bankruptcy case or receivership, insolvency or liquidation proceeding, such payment or distribution shall be delivered by the person making such payment or distribution directly to TCO for application to the payment of the Obligations. If any such payment or distribution is received by any Grantor, it shall be held by such Grantor in trust, as trustee of an express trust for the benefit of the Secured Parties, and shall forthwith be transferred and delivered by such Grantor to TCO, in the exact form received and, if necessary, duly endorsed.

(e) The obligations of the Grantors under the Lease/Purchase Facilities Documents, including their liability for the Obligations and the enforceability of the security interests granted thereby, are not contingent upon the validity, legality, enforceability, collectibility or sufficiency of any right of reimbursement, contribution or subrogation arising under this Section 2.2. The invalidity, insufficiency, unenforceability or uncollectibility of any such right shall not in any respect diminish, affect or impair any such obligation or any other claim, interest, right or remedy at any time held by any Secured Party against any Guarantor its property. The Secured Parties make no representations or warranties in respect of any such right and shall have no duty to assure, protect, enforce or ensure any such right or otherwise relating to any such right.

(f) Each Grantor reserves any and all other rights of reimbursement, contribution or subrogation at any time available to it as against any other Grantor, but (i) the exercise and enforcement of such rights shall be subject to Section 2.2(d) and (ii) neither TCO nor any other Secured Party shall ever have any duty or liability whatsoever in respect of any such right, except as provided in Section 2.2(c).

2.3. Amendments, etc. with respect to the Obligations of Tensar and Luxco. Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of Obligations of Tensar or of Luxco made by any Secured Party may be rescinded by such Secured Party and any of the Obligations of Tensar or Luxco continued, and such Obligations, or the liability of any other person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, increased, extended, amended, modified, accelerated, compromised, waived, surrendered or released by any Secured Party, and the Lease/Purchase Facilities Documents and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the parties thereto may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by any Secured Party for the payment of the Obligations of Tensar or of Luxco may be sold, exchanged, waived, surrendered or released. No Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations of Tensar or of Luxco or for the guarantee contained in this Section 2 or any property subject thereto.

2.4. Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations of Tensar or of Luxco and notice of or proof of reliance by any Secured Party upon the guarantee contained in this Section 2 or acceptance of the guarantee contained in this Section 2; the Obligations of Tensar and of Luxco shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this Section 2; and all dealings between Tensar, Luxco and any of the Guarantors, on the one hand, and the Secured Parties, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon the guarantee contained in this Section 2. Each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon Tensar, Luxco or any of the Guarantors with respect to the Obligations of Tensar or of Luxco. Each Guarantor understands and agrees that the guarantee contained in this Section 2 shall be construed as a continuing, absolute and unconditional guarantee of payment and performance (but not of collection) without regard to (a) the validity or enforceability of the Lease/Purchase Facilities Documents, any of the Obligations or any collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by any Secured Party, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by Tensar or any other person against any Secured Party, or (c) any other circumstance whatsoever (with or without notice to or knowledge of Tensar, Luxco or such Guarantor) which constitutes, or might be construed to constitute, an equitable or legal discharge of Tensar of its Obligations or of Luxco of its Obligations, or of such Guarantor under the guarantee contained in this Section 2, in bankruptcy or in any other instance. When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against any Guarantor, any Secured Party may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against Tensar, Luxco, any other Guarantor or any other person or against any collateral security or guarantee for the Obligations of Tensar or of Luxco or any right of offset with respect thereto, and any failure by any Secured Party to make any such demand, to pursue such other rights or remedies or to collect any payments from Tensar, Luxco, any other Guarantor or any

other person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of Tensar, Luxco, any other Guarantor or any other person or any such collateral security, guarantee or right of offset, shall not relieve any Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of any Secured Party against any Guarantor. For the purposes hereof “demand” shall include the commencement and continuance of any proceedings.

2.5. Reinstatement. The guarantee contained in this Section 2 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations of Tensar or of Luxco is rescinded or must otherwise be restored or returned by any Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of Tensar, Luxco or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, Tensar, Luxco or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

2.6. Payments. Each Guarantor hereby guarantees that payments hereunder will be paid to TCO without set-off or counterclaim in Dollars or, with respect to obligations arising with respect to the Luxco Murabaha Obligations, in pounds sterling, in immediately available funds at the office of TCO, as specified in the Lease Agreement, the Commodities Purchase Agreement or the Luxco Commodities Purchase Agreement, from time to time.
