Each Lender shall, before 11:00 A.M. (New York City time) on the Effective Date, make available for the account of its Applicable Lending Office to the Administrative Agent at the Administrative Agent’s Account, in same day funds, such Lender’s ratable portion of the Borrowing in accordance with the respective Commitment of such Lender and the other Lenders.

(b) The Notice of Borrowing shall be irrevocable and binding on the Borrower. If any Notice of Borrowing specifies that the Borrowing is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in the Notice of Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Advance to be made by such Lender as part of the Borrowing when such Advance, as a result of such failure, is not made on such date.

(c) If, with respect to any Eurodollar Rate Advances, Lenders owed at least a majority of the then aggregate unpaid principal amount thereof notify the Administrative Agent that the Eurodollar Rate for any Interest Period for such Advances will not adequately reflect the cost to such Lenders of making, funding or maintaining their Eurodollar Rate Advances for such Interest Period, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon (i) each such Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the Borrower that such Lenders have determined that the circumstances causing such suspension no longer exist.

(d) Notwithstanding any other provision of this Agreement, if the introduction of or any change in or in the interpretation of any law or regulation shall make it unlawful, or any central bank or other governmental authority shall assert that it is unlawful, for any Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar Rate Advances hereunder, then, on notice thereof and demand therefor by such Lender to the Borrower through the Administrative Agent, (i) each Eurodollar Rate Advance will automatically, upon such demand, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the Borrower that such Lender has determined that the circumstances causing such suspension no longer exist.

(e) (i) In the event that any Lender demands payment of costs or additional amounts pursuant to this Section 2.08 or 2.10 or asserts, pursuant to Section 2.08(d) or 2.10, that it is unlawful for such Lender to make or maintain Eurodollar Rate Advances, then such Lender shall use reasonable efforts to designate a different Applicable Lending Office for maintaining its Loans hereunder or to assign its right and obligations hereunder to another of its offices, branches or affiliates if, in the judgment of such Lender, acting reasonably, such designation or assignment (A) would eliminate or reduce amounts payable pursuant to Section 2.08 or 2.10, as the case may be, in the future, or eliminate the basis for asserting pursuant to Section 2.08(d) that it is unlawful for such Lender to make or maintain Eurodollar Rate Advances, as applicable, and (B) in each case, would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment, (ii) in the event that any Lender demands payment of costs or additional

Trident - Unsecured Credit Agreement

amounts pursuant to this Section 2.08 or Section 2.10 or asserts, pursuant to Section 2.08(d), that it is unlawful for such Lender to make Eurodollar Rate Advances then (subject to such Lender’s right to rescind such demand or assertion within 10 days after the notice from the Borrower referred to below) the Borrower may, upon 20 days’ prior written notice to such Lender and the Administrative Agent, elect to cause such Lender to assign its Advances and Commitments in full to one or more Persons selected by the Borrower so long as (a) each such Person is reasonably satisfactory to the Administrative Agent, (b) such Lender receives payment in full in cash of the outstanding principal amount of all Advances made by it and all accrued and unpaid interest thereon and all other amounts due and payable to such Lender as of the date of such assignment (including, without limitation, amounts owing pursuant to Sections 2.08, 2.10 and 10.04) and (c) each such Person assignee agrees to accept such assignment and to assume all obligations of such Lender hereunder in accordance with Section 10.07.

SECTION 2.09. Payments and Computations. (a) The Borrower shall make each payment hereunder and under the other Loan Documents, irrespective of any right of counterclaim or set-off, not later than 1:00 P.M. (New York City time) on the day when due in U.S. dollars to the Administrative Agent at the Administrative Agent’s Account in same day funds, with payments being received by the Administrative Agent after such time being deemed to have been received on the next succeeding Business Day. The Administrative Agent will promptly thereafter cause like funds to be distributed (i) if such payment by the Borrower is in respect of principal, interest, commitment fees or any other Obligation then payable hereunder and under the other Loan Documents to more than one Lender, to such Lenders for the account of their respective Applicable Lending Offices ratably in accordance with the amounts of such respective Obligations then payable to such Lenders and (ii) if such payment by the Borrower is in respect of any Obligation then payable hereunder to one Lender, to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement.

(b) The Borrower hereby authorizes each Lender and each of its Affiliates, if and to the extent payment owed to such Lender is not made by the Borrower to the Administrative Agent when due hereunder or under the other Loan Documents to charge from time to time, to the fullest extent permitted by law, against any or all of the Borrower’s accounts with such Lender or such Affiliate any amount so due.

(c) All computations of interest and of fees shall be made by the Administrative Agent on the basis of (i) with respect to Base Rate Advances, a year of 365/366 days and (ii) in all other cases, a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest, fees or commissions are payable. Each determination by the Administrative Agent of an interest rate, fee or commission hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder or under the other Loan Documents shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or commitment or letter of credit fee or commission, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to any Lender hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such

Trident - Unsecured Credit Agreement

assumption, cause to be distributed to each such Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each such Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate.

(f) Whenever any payment received by the Administrative Agent under this Agreement or any of the other Loan Documents is insufficient to pay in full all amounts due and payable to the Administrative Agent and the Lenders under or in respect of this Agreement and the other Loan Documents on any date, such payment shall be distributed by the Administrative Agent and applied by the Administrative Agent and the Lenders in the following order of priority:

(i) first, to the payment of all of the fees, indemnification payments, costs and expenses that are due and payable to the Administrative Agent (solely in its capacity as Administrative Agent) under or in respect of this Agreement and the other Loan Documents on such date;

(ii) second, to the payment of all of the indemnification payments, costs and expenses that are due and payable to the Lenders under Sections 10.04 hereof and any similar section of any of the other Loan Documents on such date, ratably based upon the respective aggregate amounts of all such indemnification payments, costs and expenses owing to the Lenders on such date;

(iii) third, to the payment of all of the amounts that are due and payable to the Administrative Agent and the Lenders under Sections 2.08 and 2.10 hereof on such date, ratably based upon the respective aggregate amounts thereof owing to the Administrative Agent and the Lenders on such date;

(iv) fourth, to the payment of all of the accrued and unpaid interest on the Obligations under or in respect of the Loan Documents that is due and payable to the Administrative Agent and the Lenders under Section 2.05(b) on such date, ratably based upon the respective aggregate amounts of all such interest owing to the Administrative Agent and the Lenders on such date;

(v) fifth, to the payment of all of the accrued and unpaid interest on the Advances that is due and payable to the Lenders under Section 2.05(a) on such date, ratably based upon the respective aggregate amounts of all such interest owing to the Lenders on such date;

(vi) sixth, to the payment of the principal amount of all of the outstanding Advances that is due and payable to the Lenders on such date, ratably based upon the respective aggregate amounts of all such principal owing to the Lenders on such date; and

(vii) seventh, to the payment of all other Obligations of the Loan Parties owing under or in respect of the Loan Documents that are due and payable to the Administrative Agent and the other Lenders on such date, ratably based upon the respective aggregate amounts of all such Obligations owing to the Administrative Agent and the other Lenders on such date.

(g) Whenever a rate of interest hereunder is calculated on the basis of a year (the “deemed year”) which contains fewer days than the actual number of days in the calendar year of calculation, such rate of interest shall be expressed as a yearly rate for purposes of the Interest Act

Trident - Unsecured Credit Agreement

(Canada) by multiplying such rate of interest by the actual number of days in the calendar year of calculation and dividing it by the number of days in the deemed year.

(h) The principle of deemed reinvestment of interest shall not apply to any interest calculation under this Agreement; all interest payments to be made hereunder shall be paid without allowance or deduction for deemed reinvestment or otherwise, before and after maturity, default and judgment. The rates of interest specified in this Agreement are intended to be nominal rates and not effective rates. Interest calculated hereunder shall be calculated using the nominal rate method and not the effective rate method of calculation.

(i) To the fullest extent permitted by applicable law, the covenant of the Borrower to pay interest at the rates provided herein shall not merge in any judgment relating to any obligation of the Borrower to the Lenders or the Administrative Agent and any provision of the Interest Act (Canada) or Judgment Interest Act (Alberta) which restricts any rate of interest set forth herein shall be inapplicable to this Agreement and is hereby waived by the Borrower.

(j) No interest or fee to be paid hereunder shall be paid at a rate exceeding the maximum rate permitted by applicable law. In the event that such interest or fee exceeds such maximum rate, such interest or fees shall be reduced or refunded, as the case may be, so as to be payable at the highest rate recoverable under applicable law.

SECTION 2.10. Taxes. (a) Unless required by Applicable Law, any and all payments by any Loan Party to or for the account of any Lender or the Agent hereunder or under any other Loan Document shall be made, in accordance with Section 2.09 or the applicable provisions of such other Loan Document, if any, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender and the Agent,

(i) taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by the federal government, state, province or foreign jurisdiction under the laws of which such Lender or the Agent, as the case may be, is organized or any political subdivision thereof and, in the case of each Lender, taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by the state, province or foreign jurisdiction of such Lender’s Applicable Lending Office or any political subdivision thereof;

(ii) any branch profits taxes imposed by the United States of America or any similar tax imposed by any other jurisdiction in which a Loan Party is located;

(iii) present or future taxes, levies, imposts, deductions, charges or withholdings imposed or levied by the Government of Canada or any province or territory thereof or any Governmental Authority therein (“Canadian Taxes”) which would not otherwise be imposed but for the fact that such Lender or the Agent does not deal at arm’s length with the Borrower for the purposes of the Income Tax Act (Canada); and

(iv) Canadian Taxes imposed or levied by reason of such Lender or the Agent carrying on business in or being connected with Canada or any province or territory thereof otherwise than by the mere holding of its interest in the Facility or the receipt of payments in respect thereof but for greater certainty tax imposed or levied on a Lender

Trident - Unsecured Credit Agreement

under Part XIII of the Income Tax Act (Canada) shall not be excluded solely by virtue of this Section 2.10(a)(iv)

(all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under any other Loan Document being hereinafter referred to as “Taxes”).

(b) If any Loan Party shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any other Loan Document to any Lender or the Agent, the sum payable by such Loan Party shall be increased as may be necessary so that after such Loan Party and the Agent have made all required deductions (including deductions applicable to additional sums payable under this Section 2.10) such Lender or the Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, such Loan Party shall make all such deductions and such Loan Party shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(c) In addition, each Loan Party shall pay any present or future stamp, documentary, excise, property, intangible, mortgage recording or similar taxes, charges or levies that arise from any payment made by such Loan Party hereunder or under any other Loan Documents or from the execution, delivery or registration of, performance under, or otherwise with respect to, this Agreement, or the other Loan Documents (hereinafter referred to as “Other Taxes”).

(d) The Loan Parties shall indemnify each Lender and the Agent for and hold them harmless against the full amount of Taxes and Other Taxes imposed or asserted by any jurisdiction on amounts payable by any Loan Party to or for the account of such Lender or the Agent hereunder, or under any other Loan Document (including any amounts payable under this Section 2.10) imposed on or paid by such Lender or the Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date such Lender or the Agent (as the case may be) makes written demand therefor.

(e) Within 30 days after the date of any payment of Taxes, the appropriate Loan Party shall furnish to the Administrative Agent, at its address referred to in Section 10.02, the original or a certified copy of a receipt evidencing such payment, to the extent such a receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Administrative Agent. In the case of any payment hereunder or under the other Loan Documents by or on behalf of a Loan Party through an account or branch outside the United States or by or on behalf of a Loan Party by a payor that is not a United States Person, if such Loan Party determines that no Taxes are payable in respect thereof, such Loan Party shall furnish, or shall cause such payor to furnish, to the Administrative Agent, at such address, an opinion of counsel acceptable to the Administrative Agent stating that such payment is exempt from Taxes. For purposes of this subsection (e) of this Section 2.10, the terms “United States” and “United States Person” shall have the meanings specified in Section 7701 of the Internal Revenue Code.

(f) Any Lender organized under the laws of a jurisdiction other than that in which a Loan Party is resident (a “Foreign Lender”) that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which a Loan Party, is resident for tax purposes, with respect to payments hereunder or under any other Loan Document shall deliver to such Loan Party (with a copy to the Administrative Agent), as reasonably requested by a Loan Party or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding; provided however (1) that such forms would not, in the good faith judgment of such Lender, require such Lender to disclose any confidential or proprietary information, (2) such Lender is legally entitled to complete, execute and

Trident - Unsecured Credit Agreement

deliver such forms, certificates or other documents and (3) the completion, execution or delivery of such forms, certificates or other documents would not, in the good faith judgment of the Lender, result in the imposition on the Lender of any additional material legal or regulatory burdens, any additional material out-of-pocket costs not indemnified hereunder, or be otherwise materially disadvantageous to such Lender.

SECTION 2.11. Sharing of Payments, Etc. If any Lender shall obtain at any time any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise, other than as a result of an assignment pursuant to Section 10.07) (a) on account of Obligations due and payable to such Lender hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations due and payable to such Lender at such time to (ii) the aggregate amount of the Obligations due and payable to all Lenders hereunder and under the other Loan Documents at such time) of payments on account of the Obligations due and payable to all Lenders hereunder and under the other Loan Documents at such time obtained by all the Lenders at such time or (b) on account of Obligations owing (but not due and payable) to such Lender hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations owing to such Lender at such time to (ii) the aggregate amount of the Obligations owing (but not due and payable) to all Lenders hereunder and under the other Loan Documents at such time) of payments on account of the Obligations owing (but not due and payable) to all Lenders hereunder and under the other Loan Documents at such time obtained by all of the Lenders at such time, such Lender shall forthwith purchase from the other Lenders such interests or participating interests in the Obligations due and payable or owing to them, as the case may be, as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each other Lender shall be rescinded and such other Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share (according to the proportion of (i) the purchase price paid to such Lender to (ii) the aggregate purchase price paid to all Lenders) of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such other Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. Upon receipt by the Administrative Agent of notice, if any, of any such purchase (or subsequent rescission), the Administrative Agent shall promptly give notice thereof to the Borrower. The Loan Parties agree that any Lender so purchasing an interest or participating interest from another Lender pursuant to this Section 2.11 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such interest or participating interest, as the case may be, as fully as if such Lender were the direct creditor of the Loan Parties in the amount of such interest or participating interest, as the case may be.

SECTION 2.12. Use of Proceeds. The proceeds of the Advances shall be available to (and the Borrower agrees that it shall use such proceeds solely to) pay transaction fees and make loans or equity contributions of the net proceeds to TEC, the proceeds of which shall be used for general corporate purposes of TEC including, without limitation, acquisitions and the funding of development activities.

SECTION 2.13. Evidence of Debt. (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Advance owing to such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. The Borrower agrees that upon notice by any Lender to the Borrower (with a copy of such notice to the Administrative Agent) to the effect that a promissory note or other evidence of indebtedness is required or appropriate in order for such Lender to evidence (whether for purposes of pledge, enforcement or otherwise) the Advances owing to, or to be made by, such Lender, the Borrower shall promptly execute and deliver to such Lender, with a copy

Trident - Unsecured Credit Agreement

to the Administrative Agent, a Note in substantially the form of Exhibit A hereto, payable to the order of such Lender in a principal amount equal to the outstanding Advances of such Lender. All references to Notes in the Loan Documents shall mean Notes, if any, to the extent issued hereunder.

(b) The Administrative Agent shall maintain accounts in which it will record (i) the Type of Advances comprising each Borrowing and, if appropriate, the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, and (iii) the amount of any sum received by the Administrative Agent from the Borrower hereunder and each Lender’s share thereof.

(c) Entries made in good faith by the Administrative Agent pursuant to subsection (b) above, and by each Lender in its account or accounts pursuant to subsection (a) above, shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from the Borrower to each Lender, under this Agreement, absent manifest error; provided, however, that the failure of the Administrative Agent or such Lender to make an entry, or any finding that an entry is incorrect, in such account or accounts shall not limit or otherwise affect the obligations of the Borrower under this Agreement.

SECTION 2.14. New Term Advances. (a) Request for New Term Advances. Provided there exists no Default, upon notice to the Administrative Agent, the Borrower may request that CS act as sole lead arranger in arranging a new term loan (the “New Term Advance”) in an aggregate amount not to exceed $25,000,000; provided that (i) the New Term Advance shall have the same maturity date as the outstanding Advance and shall be on the same terms and conditions as those set forth in this Agreement for the outstanding Advance, (ii) such request for a new term loan shall be in a minimum amount of $5,000,000 and (iii) the New Term Advance shall constitute an “Advance” for all purposes of the Loan Documents. In connection therewith, the Borrower agrees to compensate the Lenders, pursuant to Section 10.04(c), on such basis as may be agreed between the Borrower and the Administrative Agent.

(b) Proposed Lenders. The New Term Advance may be requested from existing Lenders, new prospective Lenders or a combination thereof, as selected by, and with such allocations of committed amounts as may be determined by, CS in consultation with the Borrower.

(c) Technical Amendments. The Administrative Agent shall promptly notify the Borrower and the Lenders of the amount and effective date (the “Increase Effective Date”) of the New Term Advance. In connection with the New Term Advance, this Agreement and the other Loan Documents may be amended in a writing executed and delivered by the Borrower and the Administrative Agent to reflect any technical changes necessary to give effect to the New Term Advance in accordance with the terms as set forth herein.

(d) Conditions to Effectiveness of New Term Advance. As a condition precedent to the New Term Advance, the Borrower shall deliver to the Administrative Agent a certificate of each Loan Party dated as of the Increase Effective Date (i) certifying and attaching the resolutions adopted by such Loan Party approving or consenting to the New Term Advance, and (ii) in the case of the Borrower, certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article IV and the other Loan Documents are true and correct in all material respects on and as of the Increase Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and except that for purposes of this Section 2.14, the representations and warranties contained in Section 4.01(k) shall be deemed to refer to the most recent statements furnished pursuant to clauses (ii) and (iii) of Section 5.01(e) and (B) no Default exists.

The failure of any Lender to reimburse the Agent promptly upon demand for its ratable share of any amount required to be paid by the Lender to the Agent, as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse the Agent for its ratable share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse the Agent for such other Lender’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and obligations of each Lender contained in this Section 8.05 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other Loan Documents.

SECTION 9.02. Guaranty Absolute. Each Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Loan Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Lender with respect thereto. The Obligations of each Guarantor under or in respect of this Subsidiary Guaranty are independent of the Guaranteed Obligations or any other Obligations of any other Loan Party under or in respect of the Loan Documents, and a separate action or actions may be brought and prosecuted against each Guarantor to enforce this Subsidiary Guaranty, irrespective of whether any action is brought against the Borrower or any other Loan Party or whether the Borrower or any other Loan Party is joined in any such action or actions. The liability of each Guarantor under this Subsidiary Guaranty shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to, any or all of the following:

(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations or any other Obligations of any other Loan Party under or in respect of the Loan Documents, or any other amendment or waiver of or any consent to departure from any Loan Document, including, without limitation, any increase in the Guaranteed Obligations resulting from the extension of additional credit to any Loan Party or any of its Subsidiaries or otherwise or any increase in interest rates or fees;

(c) any taking, exchange, release or non-perfection of any collateral, or any taking, release or amendment or waiver of, or consent to departure from, any other guaranty, for all or any of the Guaranteed Obligations;

(d) any manner of application of any collateral, or proceeds thereof, to all or any of the Guaranteed Obligations, or any manner of sale or other disposition of any collateral for all or any of the Guaranteed Obligations or any other Obligations of any Loan Party under the Loan Documents or any other assets of any Loan Party or any of its Subsidiaries;

(e) any change, restructuring or termination of the corporate structure or existence of any Loan Party or any of its Subsidiaries;

(f) any failure of any Lender to disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party now or hereafter known to such Lender (each Guarantor waiving any duty on the part of the Lenders to disclose such information);

Trident - Unsecured Credit Agreement

(g) the failure of any other Person to execute or deliver this Agreement, any Guaranty Supplement or any other guaranty or agreement or the release or reduction of liability of any Guarantor or other guarantor or surety with respect to the Guaranteed Obligations; or

(h) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by any Lender that might otherwise constitute a defense available to, or a discharge of, any Loan Party or any other guarantor or surety.

(g) Each Lender may without the consent of the Borrower, the other Lenders or the Administrative Agent sell participations to one or more Persons (other than a natural person or any Loan Party or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments, the Advances owing to it and the Note or Notes (if any) held by it); provided, however, that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Note for all purposes of this Agreement and (iv) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the participant, agree to any amendment, modification or waiver that would reduce the principal of, or interest on, the Advances or any fees or other amounts payable hereunder, in each case to the extent subject to such participation, postpone any date fixed for any payment of principal of, or interest on, the Advances or any fees or other amounts payable hereunder, in each case to the extent subject to such participation, or release all or substantially all of the value of the Subsidiary Guaranties. Subject to paragraph (h) of this Section, the Borrower agrees that each participant shall be entitled to the benefits of Sections 2.08 and 2.10 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each participant shall also be entitled to the benefits of Section 10.05 as though it were a Lender, provided such participant agrees to be subject to Section 2.11 as though it were a Lender.

(h) A participant shall not be entitled to receive any greater payment under Sections 2.08 and 2.10 than the applicable Lender would have been entitled to receive with respect to the participation sold to such participant, unless the sale of the participation to such participant is made with the Borrower’s prior written consent. A participant that would be Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.10 unless the Borrower is notified of the participation sold to such participant and such participant agrees, for the benefit of the Borrower, to comply with Section 2.10(f) as though it were a Lender. For greater certainty, in no event shall the Borrower be required to pay a greater amount in aggregate under Section 2.10 as a result of the sale by a Lender of a participation to a participant than the Borrower was required to pay to such Lender prior to such sale, except to the extent agreed to by the Borrower in writing.

Trident - Unsecured Credit Agreement

(i) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 10.07, disclose to the assignee or participant or proposed assignee or participant any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided, however, that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to preserve the confidentiality of any Confidential Information received by it from such Lender.

(j) Notwithstanding any other provision set forth in this Agreement, any Lender may at any time create a security interest in all or any portion of its rights under this Agreement (including, without limitation, the Advances owing to it and the Note or Notes (if any) held by it) in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledge or assignee for such Lender as a party hereto.

(k) Notwithstanding anything to the contrary contained herein, any Lender that is a Fund may create a security interest in all or any portion of the Advances owing to it and any Note or Notes held by it to the trustee for holders of obligations owed, or securities issued, by such Fund as security for such obligations or securities; provided that unless and until such trustee actually becomes a Lender in compliance with the other provisions of this Section 10.07, (i) no such pledge shall release the pledging Lender from any of its obligations under the Loan Documents and (ii) such trustee shall not be entitled to exercise any of the rights of a Lender under the Loan Documents even though such trustee may have acquired ownership rights with respect to the pledged interest through foreclosure or otherwise.

(l) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower (an “SPC”) the option to provide all or any part of any Advance that such Granting Lender would otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Advance and (ii) if an SPC elects not to exercise such option or otherwise fails to make all or any part of such Advance, the Granting Lender shall be obligated to make such Advance pursuant to the terms hereof. The making of an Advance by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Advance were made by such Granting Lender. Each party hereto hereby agrees that (i) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would be liable, (ii) no SPC shall be entitled to the benefits of Sections 2.08 and 2.10 (or any other increased costs protection provision) and (iii) the Granting Lender shall for all purposes, including, without limitation, the approval of any amendment or waiver of any provision of any Loan Document, remain the Lender of record hereunder. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior Debt of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding under the laws of the United States or any State thereof. Notwithstanding anything to the contrary contained in this Agreement, any SPC may (i) with notice to, but without prior consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or any portion of its interest in any Advance to the Granting Lender and (ii) disclose on a confidential basis any non-public information relating to its funding of Advances to any rating agency, commercial paper dealer or provider of any surety or guarantee or credit or liquidity enhancement to such SPC. This subsection (l) may not be amended without the prior written consent of each Granting Lender, all or any part of whose Advances are being funded by the SPC at the time of such amendment.

SECTION 10.09. Confidentiality. Neither the Agent nor any Lender shall disclose any Confidential Information to any Person without the consent of the Borrower, other than (a) to the Agent’s or such Lender’s Affiliates and their officers, directors, employees, agents and advisors and to actual or prospective assignees and participants, and then only on a confidential basis, (b) as required by any law, rule or regulation or judicial process, (c) as requested or required by any state, Federal or foreign authority or examiner (including the National Association of Insurance Commissioners or any similar organization or quasi-regulatory authority) regulating such Lender, (d) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Loan Parties received by it from such Lender, (e) in connection with any litigation or proceeding to which the Agent or such Lender or any of its Affiliates may be a party or (f) in connection with the exercise of any right or remedy under this Agreement or any other Loan Document. In addition, neither the Agent or any Lender shall use any Confidential Information other than in connection with the transactions contemplated hereby and by the other Loan Documents including, without limitation, in connection with any proposed assignment or participation (subject to the limitations in clause (a) above) or in connection with the exercise of any right or remedy under this Agreement or any other Loan Document.

SECTION 10.10. Patriot Act Notice. Each Lender and the Agent (for itself and not on behalf of any Lender) hereby notifies the Loan Parties that pursuant to any requirements it may have under the Patriot Act, it may be required to obtain, verify and record information that identifies each Loan Party, which information includes the name and address of such Loan Party and other information that will allow such Lender or the Agent, as applicable, to identify such Loan Party in accordance with the Patriot Act. The Borrower shall, and shall cause each of its Subsidiaries to, provide to the extent commercially reasonable, such information and take such actions as are reasonably requested by the Administrative Agent or any Lender in order to assist the Administrative Agent and the Lenders in maintaining compliance with the Patriot Act.

SECTION 10.11. Jurisdiction, Etc. (a) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any of the other Loan Documents to which it is a party, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the fullest extent permitted by law, in such Federal court.

FORM OF
SOLVENCY CERTIFICATE

TRIDENT RESOURCES CORP.

Trident Resources Corp., a Delaware corporation (the “Borrower”), hereby certifies that (the “Officer”) is the Chief Financial Officer of the Borrower and is duly authorized to execute this Solvency Certificate on behalf of the Borrower, which is being delivered pursuant to Section 3.01(a)(iv) of the Credit Agreement dated as of April 25, 2006 (the “Credit Agreement”) among the Borrower, the Subsidiary Guarantors, the Lenders and Credit Suisse, Toronto Branch, as Administrative Agent (in such capacity, the “Administrative Agent”; together with the Lenders party to the Credit Agreement, the “Lender Group”). Unless otherwise defined herein, terms defined in the Credit Agreement are used herein as therein defined.

The Borrower hereby certifies that the Officer is generally familiar with the properties, prospects, businesses, assets, finances and operations of the Borrower and each of its subsidiaries and has carefully reviewed the Credit Agreement and the other Loan Documents that the Officer has deemed relevant to each Guarantor and the contents of this Solvency Certificate and, in connection herewith, has reviewed such other documentation and information and has made such investigation and inquiries as the Officer deems necessary and prudent therefor. The Borrower hereby further certifies that the financial information and assumptions which underlie and form the basis for the representations made in this Solvency Certificate were reasonable when made and were made in good faith and continue to be reasonable as of the date hereof.

The Borrower understands that the Lenders are relying on the truth and accuracy of this Solvency Certificate in connection with the transactions contemplated by the Credit Agreement and the other Loan Documents (referred to in the Credit Agreement).

The Borrower hereby certifies that:

1. The financial data and projections set forth in the materials delivered by or on behalf of the Loan Parties in connection with Section 5.01(e) of the Credit Agreement (the “Financial Statements”) were prepared in good faith on the basis of the assumptions stated therein, which assumptions are fair in the light of the conditions existing on the date hereof (it being understood that such data and projections represent a business plan and do not constitute a forecast or projection and there is no assurance that such business plan can be fully attained).

2. On the date hereof, before and after giving effect to the consummation of the Transaction and any other transactions contemplated by the Credit Agreement and the other Loan Documents, the fair value of the property of the Borrower and its Subsidiaries, on a Consolidated basis, is greater than the total amount of liabilities (including, without limitation, contingent liabilities but excluding any intercompany indebtedness existing as of the date hereof) of the Borrower and its Subsidiaries, on a Consolidated basis.

3. On the date hereof, before and after giving effect to the consummation of the Transaction and any other transactions contemplated by the Credit Agreement and the other Loan Documents, the present fair saleable value of the assets of the Borrower and its Subsidiaries, on a Consolidated basis, is not less than the amount that will be required to pay the probable liabilities of the Borrower and its Subsidiaries on their debts, on a Consolidated basis, (excluding any intercompany indebtedness existing as of the date hereof) as such debts become absolute and matured.

Exhibit E - Form of Solvency Certificate

4. On the date hereof, before and after giving effect to the consummation of the Transaction and any other transactions contemplated by the Credit Agreement and other Loan Documents, the Borrower and its Subsidiaries, taken as a whole, do not intend to, and do not believe that they will, incur debts or liabilities (including, without limitation, contingent liabilities but excluding any intercompany indebtedness existing as of the date hereof) beyond the ability of the Borrower and its Subsidiaries, on a Consolidated basis, to pay such debts and liabilities as such debts and liabilities mature.

5. On the date hereof, before and after giving effect to the consummation of the Transaction and any other transactions contemplated by the Credit Agreement and the other Loan Documents, the Borrower and its Subsidiaries, on a Consolidated basis, are not engaged in business or a transaction, or are not about to engage in business or a transaction, for which the property of the Borrower and its Subsidiaries, on a Consolidated basis, would constitute an unreasonably small capital.

6. The Borrower and its Subsidiaries, in consummating any of the transactions contemplated by the Credit Agreement and the other Loan Documents, do not intend to hinder, delay or defraud either present or future creditors or any other person to which the Borrower or any of its Subsidiaries are or will become, on or after the date hereof, indebted.

7. Each of the Borrower and its Subsidiaries are not Persons who are bankrupt and are not Persons who reside, carry on business or have property in Canada, whose liabilities to creditors provable as claims under the Canadian Federal Bankruptcy and Insolvency Act amount to one thousand dollars, and

(a) who are for any reason unable to meet their obligations as they generally become due,

(b) who have ceased paying their current obligations in the ordinary course of business as they generally become due, or

(c) the aggregate of whose property is not, at a fair valuation, sufficient, or, if disposed of at a fairly conducted sale under legal process, would not be sufficient to enable payment of all their obligations, due and accruing due.

8. In reaching the conclusions set forth in this Solvency Certificate, the Borrower has considered, among other things:

	(a)		the cash and other current assets of each of the Borrower and its Subsidiaries;

	(b)		the contribution rights that each Guarantor will have against each of the other Guarantors and the subrogation rights that each Guarantor (other than the Borrower) will have against the Borrower;

	(c)		all unliquidated and contingent liabilities of the Borrower and its Subsidiaries, including, without limitation, any claims arising out of pending or threatened litigation against such Borrower and its Subsidiaries, or any of its respective property and assets, and in so doing, the Borrower has, in good faith, computed the maximum amount of such unliquidated and contingent liabilities as the maximum amount that, in light of all the facts and circumstances existing on the date hereof, represents the amount that can reasonably be expected to become an actual or matured liability;

	(d)		all of the other obligations and liabilities of the Borrower and its Subsidiaries, whether matured or unmatured, liquidated or unliquidated, disputed or

Exhibit E - Form of Solvency Certificate

			undisputed, secured or unsecured, subordinated, absolute, fixed or contingent, including, without limitation, any claims arising out of pending or threatened litigation against the Borrower and its Subsidiaries or any of its property and assets;

	(e)		the ability of each Subsidiary (other than the Borrower) to receive financing from the Borrower or other third party lenders (without taking into account any restrictions contained in the Credit Agreement) after the date hereof on customary terms;

	(f)		the anticipated interest payable on the Advances and the fees payable under the Credit Agreement;

	(g)		the level of capital customarily maintained by each the Borrower and its Subsidiaries and other entities engaged in the same or similar business as the business of such Persons;

	(h)		the values of real property, equipment, inventory, accounts receivables, computer software, customer lists, trade secrets and proprietary information, leases, patents, trademarks, goodwill, and all other property of the Borrower and its Subsidiaries, real and personal, tangible and intangible;

	(i)		the experience of management of the Borrower and its Subsidiaries in acquiring and disposing of its assets and managing its business; and

	(j)		historical and anticipated growth in sales volume of the Borrower and its Subsidiaries, and in the income stream generated by such Person as reflected in, among other things, the cash flow statements comprising part of the Financial Statements.

Delivery of an executed counterpart of a signature page to this Solvency Certificate by telecopier shall be effective as delivery of a manually executed counterpart of this Solvency Certificate.

IN WITNESS WHEREOF, the undersigned has executed this Solvency Certificate on behalf of the Borrower this 25th day of April, 2006.
