(b) In fulfilling its obligations hereunder with respect to the Supported Obligations, TECO hereby irrevocably and unconditionally guarantees, promises and agrees to perform and comply with the Construction Contract. The words "perform and comply with" are used in their most comprehensive sense and include without limitation (x) the payment of all 7 costs and expenses with respect to the achievement of Final Acceptance of the Project within the time and in the manner set forth in the Construction Contract, (y) the payment, satisfaction or discharge of all Liens arising out of, or relating to, any work associated with the Construction Contract or any subcontracts related thereto that are or may be imposed upon or asserted against the Project and (z) the defense and indemnification of the Beneficiaries against all such Liens, whether arising from the furnishing of labor, materials, supplies or equipment, from taxes, assessments, fees or other charges, from injuries or damage to persons or property, or otherwise, in each case, except as provided in clause (ii) below and Section 2.1(c), as and to the extent required by the terms of the Construction Contract.

(c) TECO acknowledges and agrees that the Actual Construction Cost will exceed the Pre-Bankruptcy EPC Cost. TECO further acknowledges and agrees that: (x) Borrower shall not be liable for the difference between (i) the Actual Construction Costs (less the amount of any change orders under the Construction Contract increasing the Separated Contract Price entered into after November 30, 2001 in accordance with the Credit Agreement (other than those pending change orders described in clause (b) of the definition of Pre-Bankruptcy EPC Cost)) and (ii) the sum of (A) the Pre-Bankruptcy EPC Cost plus (B) the aggregate amount of the Retainage L/C Proceeds; (y) the sum of the amounts set forth on Schedule 1 attached hereto reflects the estimated amount (as of the date hereof) by which the Actual Construction Cost will exceed the sum of the Pre-Bankruptcy EPC Cost plus the aggregate amount of Retainage L/C Proceeds; and (z) TECO shall be liable to pay the actual amount by which the Actual Construction Cost (less the amount of any change orders under the Construction Contract increasing the Separated Contract Price entered into after November 30, 2001 in accordance with the Credit Agreement (other than those pending change orders 8 described in clause (b) of the definition of Pre-Bankruptcy EPC Cost)) exceeds the sum of the Pre-Bankruptcy EPC Cost plus the aggregate amount of Retainage L/C Proceeds. (d) To implement the agreement set forth in clause (c) above, subject to the following sentence, (i) not later than the last Banking Day of each month commencing in February 2002, TECO shall be obligated to deposit into the account referred to below an aggregate amount equal to the amount set forth on Schedule 1 attached hereto corresponding to such month, (ii) at such time, if ever, as the amount by which the Actual Construction Cost (less the amount of any change orders under the Construction Contract increasing the Separated Contract Price entered into after November 30, 2001 in accordance with the Credit Agreement (other than those pending change orders described in clause (b) of the definition of Pre-Bankruptcy EPC Cost)) exceeds the sum of the Pre-Bankruptcy EPC Cost plus the aggregate amount of Retainage L/C Proceeds by more than the aggregate amount set forth on Schedule 1 attached hereto, TECO shall deposit such excess amounts in the account referred to below as such excess amounts become due and payable and use the proceeds thereof to pay any remaining amounts due to Contractor, Subcontractors and any other Person to which Actual Construction Costs are then due and owing, and (iii) at such time, if ever, that TECO provides Administrative Agent evidence, satisfactory to Administrative Agent (determination of which shall not be unreasonably withheld or delayed), that the amount by which the Actual Construction Cost (less the amount of any change orders under the Construction Contract increasing the Separated Contract Price entered into after November 30, 2001 in accordance with the Credit Agreement (other than those pending change orders described in clause (b) of the definition of Pre-Bankruptcy EPC Cost)) exceeds the sum of the Pre-Bankruptcy EPC Cost plus the aggregate amount of the Retainage L/C Proceeds is less than the amounts set forth on Schedule 1 by more than $5,000,000, TECO and Administrative Agent shall amend Schedule 1 to reflect any agreed upon adjustments. Notwithstanding the immediately preceding sentence, in any month where funds are not being paid to Persons performing work included within the "Scope of Work" described in the Construction Contract, TECO's obligation to pay or deposit any amounts referred to in this Section 2.1(d) shall be deferred until such date as payments to such Persons resume, at which time TECO shall deposit all amounts deferred pursuant to this sentence into the account described below. Within one Banking Day after the date hereof, TECO shall establish an account with Depositary Agent into which all amounts to be paid by TECO pursuant to this Section 2.1(c) shall be deposited. Concurrently therewith, TECO shall execute a control agreement in favor of Administrative Agent granting a first priority security interest in such account to Administrative Agent. Provided no Event of Default exists, TECO shall have the right to withdraw amounts in such account and advance such amounts to Borrower to pay Contractor, Subcontractors and/or any other Person to which Actual Construction Costs are then due and owing as and when amounts are due such Persons. At any time an Event of Default exists, TECO shall have no rights of withdrawal with respect to such account and, in any event, Administrative Agent's only rights with respect to such account shall be to pay to Contractor, Subcontractors and/or any other Person to which Actual Construction Costs are then due and owing with amounts in such account. To the extent any amounts are remaining in such account after Final Acceptance has been achieved, such amounts shall be paid to TECO in accordance with TECO's instructions. 9 (e) Except as provided in clauses (c) and (d) of this Section 2.1, but notwithstanding any other provision of this Undertaking to the contrary, the aggregate amount expended by TECO in the performance of this Undertaking shall not exceed the then-applicable Undertaking Limit. 2.2 Obligations Absolute and Unconditional. -------------------------------------- (a) The obligations of TECO hereunder are primary obligations of TECO and are an absolute, unconditional, continuing and irrevocable guaranty of payment and performance of the Supported Obligations and not of collectibility and are in no way conditioned on or contingent upon any attempt to enforce in whole or in part Contractor's liabilities and obligations to the Beneficiaries. If Contractor shall fail to pay or perform any of the Supported Obligations as and when they are due or required, TECO shall forthwith perform or pay such Supported Obligations (and in the case of any payment required hereunder, in immediately available funds), and each such failure by Contractor to pay or perform a Supported Obligation shall give rise to a separate cause of action herewith, and separate suits may be brought hereunder as each cause of action arises. (b) Subject to the following sentence, the Beneficiaries may, at any time and from time to time (whether or not after revocation or termination of this Undertaking) without the consent of or notice to TECO, except such notice as may be required by applicable law which cannot be waived or any notice required hereunder, without incurring responsibility to TECO, without impairing or releasing the obligations of TECO hereunder, upon or without any terms or conditions and in whole or in part, (i) change the manner, place and terms of payment or performance or change or extend the time of such payment or performance of, renew, or alter any Supported Obligation, or any obligations and liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof or in any manner modify, amend or supplement the terms of the Construction Contract, any documents, instruments or agreements executed in connection therewith, and the undertaking herein made shall apply to the Supported Obligations, as changed, extended, renewed, modified, amended, supplemented or altered in any manner; (ii) exercise or refrain from exercising any rights against Contractor or others (including TECO) or otherwise act or refrain from acting; (iii) add or release any other guarantor from its obligations without affecting or impairing the obligations of TECO hereunder; (iv) settle or compromise any Supported Obligations and/or any obligations and liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any obligations and liabilities which may be due to the Beneficiaries or others; (v) sell, exchange, release, surrender, realize upon or otherwise deal with in any manner or in any order any property by whomsoever pledged or mortgaged to secure or howsoever securing the Supported Obligations or any liabilities or obligations (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof and/or any offset thereagainst; (vi) apply any sums by whomsoever paid or howsoever realized to any obligations and liabilities of Contractor to the Beneficiaries under the Construction Contract in the manner provided therein regardless of what obligations and liabilities remain unpaid; (vii) consent to or waive any breach of, or any act, omission or default under, the Construction Contract; and/or (viii) act or fail to act in any manner referred to in this Undertaking which may deprive TECO of its right to subrogation against Contractor or any other 10 Person to recover full indemnity for any payments made pursuant to this Undertaking or of its right of contribution against any other party. Notwithstanding any provision of this Undertaking to the contrary, no amendment to or modification of the Construction Contract resulting from the Banks', or any agent acting on behalf of, or transferee of, the Banks acting as Owner under, and as defined in, the Construction Contract (to the exclusion of TECO) pursuant to remedies provided in the Credit Documents shall affect or modify the Support Obligations in any manner without the prior written consent of TECO. (c) No invalidity, irregularity or unenforceability of the Supported Obligations or invalidity, irregularity, unenforceability or nonperfection of any collateral therefor, shall affect, impair, or be a defense to this Undertaking, which is a primary obligation of TECO. (d) This is a continuing Undertaking and all obligations to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. In the event that, notwithstanding the provisions of Section 2.2(a) hereof, this Undertaking shall be deemed revocable in accordance with applicable law, then to the extent permitted by applicable law any such revocation shall become effective only upon receipt by the Beneficiaries of written notice of revocation signed by TECO. To the extent permitted by applicable law, no revocation or termination hereof shall affect in any manner rights arising under this Undertaking with respect to Supported Obligations arising prior to receipt by the Beneficiaries of written notice of such revocation or termination and the sole effect of revocation and termination hereof shall be to exclude from this Undertaking Supported Obligations thereafter arising which are unconnected with Supported Obligations theretofore arising or transactions theretofore entered into. (e) Except as otherwise provided by law or by the terms of the Construction Contract, each payment to be made by TECO to, or on behalf of, the Beneficiaries hereunder shall be made without deduction or withholding for or on account of Taxes. If such deduction or withholding is so required, TECO shall, upon notice thereof from any Beneficiary, (i) pay the amount required to be deducted or withheld to the appropriate authorities before penalties attach thereto or interest accrues thereon (including deductions from amounts payable under this Section 2.2(e)), (ii) on or before the 30th day after payment of such amount, forward to such Beneficiary an official receipt evidencing such payment (or a certified copy thereof), and (iii) in the case of any such deduction or withholding, forthwith pay to such Beneficiary such additional amount as may be necessary to ensure that the net amount actually received by such Beneficiary, free and clear of such Taxes, including any Taxes on such additional amount, is equal to the amount that such Beneficiary would have received had there been no such deduction or withholding. 2.3 Waiver. ------- (a) Subject to Section 2.3(b) and the last sentence of Section 2.2(a), to the extent permitted by applicable law, TECO hereby unconditionally and irrevocably waives and relinquishes all rights and remedies accorded by applicable law to sureties or guarantors and agrees not to assert or take advantage of any such rights or remedies, including (i) any right to 11 require the Beneficiaries to proceed against Contractor or any other Person or to proceed against or exhaust any security held

obligation or evidence of indebtedness held by the Beneficiaries in connection with any Supported Obligations, (iv) any defense based upon an election of remedies by the Beneficiaries, including an

reimbursement, or both, (v) any defense based on any offset against any amounts which may be owed by any Person to TECO for any reason whatsoever, (vi) any defense based on any act, failure to act,

Beneficiaries have reason to believe that any such facts materially increase the risk beyond that which TECO intends to assume, or have reason to believe that such facts are unknown to TECO, or have a

circumstances bearing on the risk of non-payment of any obligations and liabilities hereby guaranteed, (x) any defense arising because of any Beneficiary's election, in any proceeding instituted under the Federal Bankruptcy Code, of the application of Section 1111(b)(2) of the Federal Bankruptcy Code, (xi) any defense based upon any borrowing or grant of a security interest under Section 364 of the
