SECTION 8. PREPAYMENT OF THE NOTES.

Section 8.1 Required Prepayments. No regular scheduled payment of the principal of the Notes of any series is required prior to the date of its maturity.

Section 8.2 Optional Prepayments. The Company may, at its option, upon notice provided below, prepay at any time all, or from time to time any part of, the Notes in an amount not less than 5% of the aggregate principal amount of the Notes then outstanding, at 100% of the principal amount so prepaid, together with interest accrued thereon to the date of such prepayment, plus the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each holder of Notes written notice of each optional prepayment under this Section 8.2 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the Notes on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.4), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall also be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to any prepayment pursuant to this Section 8.2, the Company shall deliver to each holder of Notes a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the specified prepayment date.

Section 8.3 Redemption for Reasons of Taxation. If in the good faith opinion of the Board of Directors of the Company (which determination shall be accompanied by a written opinion of an independent tax counsel of recognized national standing to the same such effect), the Company would be obligated to pay a Tax Indemnity Amount greater than 5% of any interest payment in respect of the applicable series of Notes pursuant to Section 14.3 as a result of a change of tax law after the date of this Agreement, then and in such event, but only in such event, on the occasion of any payment pursuant to Section 14.3, the Company may, by giving written notice to each holder of the applicable series of Notes not less than 30 days nor more than 60 days before the date fixed for a prepayment pursuant to this Section 8.3, prepay all (but not less than all) of the applicable series of outstanding Notes with respect to which any such amounts will be payable by payment of 100% of the principal amount of the Notes and accrued interest thereon to the date of such prepayment, together with any amount then due and owing pursuant to Section 14.3, but without premium. At any time on or after the date on which any holder of the Notes receives notice pursuant to this Section 8.3 that the Company intends to prepay the applicable series of Notes held by such holder pursuant to this Section 8.3, but not less than two Business Days prior to the date scheduled for such prepayment, such holder may, by notice delivered to the Company in the manner provided in Section 18, irrevocably waive any and all right to any payment of any additional amounts the Company would become obligated to pay under Section 14.3 as a result of any deduction or withholding which would be required with respect to any Relevant Tax, such waiver to be effective as of the date of delivery by the Company of such notice of prepayment and to survive termination of this Agreement and

“Reinvestment Yield” means, with respect to the Called Principal of any Pounds Sterling Note, the sum of (x) 0.50% plus (y) the yield to maturity implied by (i) the yields reported as of 10:00 A.M. (London time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PXUK” (or such other display as may replace Page PXUK) on Bloomberg Financial Markets (“Bloomberg”) for the then most actively traded, on the run UK Gilt securities (the “Reference Stock”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date or (ii) if (a) Page PXUK (or such other display as may replace Page PXUK) is not published on that day, or (b) there is a manifest error in the displayed figures or (c) the calculation in Page PXUK ceases to be in keeping with the Formula for the Calculation of Redemption Yields indicated in the United Kingdom Debt Management Office notice entitled “Formulae for Calculating Gilt Prices from Yields”, page 4, Section One: Price/Yield Formulae “Conventional Gilts: Double-dated and Undated Gilts with assumed (or Actual) Redemption on a Quasi-Coupon Date” published on June 8, 1998, as supplemented, amended or replaced from time to time (the “Formula”), then the gross redemption yield calculated on the basis of the arithmetic mean (to three decimal places 0.0005 rounded down) of the mid -market price for the Reference Stock on a dealing basis by three authorized leading market makers in the gilt-edged market as at or about 11:00 a.m. London time on the second Business Day preceding the Settlement Date according to the Formula.

“Reinvestment Yield” means, with respect to the Called Principal of any Cdn. Dollar Note, the sum of (x) 0.50% plus (y) (i) the yield to maturity, as of 10:00 a.m. (New York City time) on the third Business Day preceding the Settlement Date with respect to such Called Principal, as provided by two major Canadian investment dealers designated by the holders of at least 51% in principal amount of the Cdn. Dollar Notes (the “Designated Investment Dealers”), for a non-callable Government of Canada bond in Cdn. Dollars having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the average of the yields for such securities as determined by the Designated Investment Dealers.

In the case of each determination under clause (i) or (ii), as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by interpolating linearly between (1) the non-callable Government of Canada bond in Cdn. Dollars with the maturity closest to and greater than the Remaining Average Life of such Called Principal and (2) the non-callable Government of Canada bond in Cdn. Dollars with the maturity closest to and less than the Remaining Average Life of such Called Principal. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Cdn. Dollar Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (a) such Called Principal into (b) the sum of the products obtained by multiplying (i) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (ii) the number of years (calculated to the nearest one-twelfth year) that will elapse

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

(f) Certain Definitions. “Change in Control” shall be deemed to have occurred if any person (as such term is used in Section 13(d) and Section 14(d)(2) of the Exchange Act as in effect on the date of the Closing) or related persons constituting a group (as such term is used in Rule 13d-5 under the Exchange Act) (in any such case, the “Acquiror” or the “Acquirors”):

(i) become the “beneficial owners” (as such term is used in Rule 13d-3 under the Exchange Act as in effect on the date of the Closing), directly or indirectly of more than 50% of the Equity Interests of the Company; or

(ii) acquire after the date of the Closing, the power to elect, appoint or cause the election or appointment of at least a majority of the members of the board of directors (or the legal equivalent thereof) of the Company.

(g) All calculations contemplated in this Section 8.8 involving the capital stock of any Person shall be made with the assumption that all convertible Securities of such Person then outstanding and all convertible Securities issuable upon the exercise of any warrants, options and other rights outstanding at such time were converted at such time and that all options, warrants and similar rights to acquire shares of capital stock of such Person were exercised at such time.

Such notice shall contain and constitute an offer to prepay the Notes as provided in Section 8A.2(b).

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

(b) The offer to prepay Notes contemplated by Section 8A.2(a) shall be an offer to prepay, in accordance with this Section 8A.2, a principal amount of Notes determined as provided in Sections 8A.2(e) and 8A.2(f) on one of two dates specified in such offer, the first of which shall be the second Business Day after the Initial Acceptance Date (the “Initial Special Offer Prepayment Date”) and the second of which shall be the second Business Day after the Delayed Acceptance Date (the “Delayed Special Offer Prepayment Date”). Such offer shall also specify (i) the principal amount of Debt outstanding under the Bank Facility paid or to be paid in connection with such Special Prepayment Offer Event and (ii) the principal amount of each Note and 2010 Note offered to be paid on the Initial Special Offer Prepayment Date or the Delayed Special Offer Prepayment Date, as the case may be, and shall state that such principal amount, the Make-Whole Amount (determined consistently with Section 8B) payable in respect thereof and interest accrued on such principal amount will be paid (x) on the Initial Special Offer Prepayment Date for all holders of Notes that accept such offer on or prior to the fifth Business Day after the date of such offer (the “Initial Acceptance Date”) and (y) on the Delayed Special Offer Prepayment Date for all holders of Notes that either accept such offer on or prior to the 20th business day after the date of such offer (the “Delayed Acceptance Date”) or fail to respond to such offer prior to such date.

(c) A holder of Notes may accept or reject the offer to prepay made pursuant to this Section 8A.2 by causing a notice of such acceptance to be delivered to the Company not later than the Delayed Acceptance Date. A failure by a holder of Notes to respond to an offer of prepayment made pursuant to this Section 8A.2 shall be deemed to constitute an acceptance of such offer.

(d) Prepayment of the Notes to be prepaid pursuant to this Section 8A.2 shall be at 100% of the principal amount to be prepaid, together with interest on such principal amount and the Make-Whole Amount (determined consistently with Section 8B) determined for the Initial Special Offer Prepayment Date.

(e) Except as provided in Section 8A.2(f), in the event any Special Prepayment Offer Event occurs, the Company shall apply the Net Special Prepayment Proceeds from such Special Prepayment Offer Event to prepay, or to offer to prepay, as applicable, to the extent of such proceeds and in accordance with the Intercreditor Agreement and this Section 8A.2(e), the principal amount of Senior Pro Rata Debt outstanding on the date on which such Special Prepayment Offer Event occurs, together with, in the case of the Notes and the 2010 Notes, the Make-Whole Amount (determined consistently with Section 8B) and the 2010 Make-Whole Amount, respectively, owing in respect of any such prepayment. In addition, the Company shall pay accrued interest on the principal amount so paid on the date of any such prepayment. A Ratable Amount shall be allocable to the Notes and such Ratable Amount shall be allocated among all of the Notes outstanding on the second Business Day preceding the Initial Special Offer Prepayment Date (without regard to series) pro rata in accordance with the principal amount of each Note outstanding on such Business Day. The amount so allocated to any Note shall be applied to the prepayment of principal of such Note to the maximum extent possible (but rounded to the nearest 1,000 U.S. Dollars, Pounds Sterling or Cdn. Dollars, as applicable) so that the remaining portion of such amount is sufficient to pay the Make-Whole Amount (determined

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

consistently with Section 8B) due on the prepaid principal amount of such Note. For the avoidance of doubt, the amount so allocated shall not be applied to the payment of interest payable in connection with such offer, which interest shall be paid by the Company with other funds.

(f)

(i) In the event of a Bank Commitment Reduction Event, the entire amount of the Net Special Prepayment Proceeds shall be applied to an offer to prepay the Notes and the 2010 Notes in accordance with this Section 8A.2 determined as if Senior Pro Rata Debt (as used in the definition of “Ratable Amount”) included only the Notes and the 2010 Notes.

(ii) In the event of a Swan Hills Disposition Event, the Net Special Prepayment Proceeds arising therefrom shall be applied first, to repay the Priority Amount and second, to an offer to prepay the Notes and the 2010 Notes in accordance with this Section 8A.2 determined as if Senior Pro Rata Debt (as used in the definition of “Ratable Amount”) included only the Notes and the 2010 Notes.

(iii) In the event that the portion of any Net Special Prepayment Proceeds allocable to any Senior Pro Rata Debt (other than the Notes) exceeds the outstanding principal amount thereof, such excess shall be applied to a prepayment of the Notes, ratably in accordance with the respective principal amounts thereof.

(g) Notwithstanding Section 8.7, in calculating the Make-Whole Amount payable in respect of the principal amount of any Notes to be prepaid on either an Initial Special Offer Prepayment Date or a Delayed Special Offer Prepayment Date in respect of a Special Prepayment Offer Event, in both cases the “Settlement Date” shall mean, with respect to the Called Principal of any Note, the Initial Special Prepayment Offer Date.

(h) Notwithstanding any provision in this Section 8A, if the Company makes an offer to repay, redeem or purchase the Notes as set forth in this Section 8A and some or all of the holders do not accept such offer, the Company may use the remaining amounts that were otherwise allocated to fund such unaccepted offer to do any one or more of the following in its discretion: (A) prepay the Notes on a pro rata basis in accordance with Section 8.2, (B) make a non-permanent repayment of any borrowing under the Bank Facility, and (C) use such amounts for its general corporate purposes.

SECTION 8B. MAKE-WHOLE AMOUNT.

Notwithstanding any other provision of this Agreement:

(a) any reference to “interest” in Section 8.7 shall continue to refer to interest at the applicable Original Coupon;

(b) any Make-Whole Amount payable pursuant to this Agreement shall be computed on the basis that the applicable Original Coupon continues to apply to the Notes; and

Section 9.6 Nature of Business. Neither the Company nor any\ ~~Restricted~~\ Subsidiary will engage in any business if, as a result, the general nature of the business, taken on a consolidated basis, which would then be engaged in by the Company and the\ ~~Restricted~~\ Subsidiaries would be substantially changed from its business relating to the development, production, processing and transportation of hydrocarbons.

Section 9.11 Further Assurances. The Company will, and will cause each of the Subsidiary Guarantors, as applicable, to, promptly upon request by the Collateral Agent on behalf of the Secured Parties, (a) correct any material defect or error that may be discovered in any Financing Document or in the execution, acknowledgment, filing or recordation thereof, and (b) execute, acknowledge, deliver, record, re-record, file, re-file, register and re-register any and all such further acts, deeds, certificates, assurances and other instruments as the Collateral Agent, may reasonably request from time to time in order to (i) carry out more effectively the purposes of the Security Documents, (ii) to the fullest extent permitted by applicable law, subject any Obligor’s properties, assets, rights or interests to the Liens now or hereafter created by any of the Security Documents, (iii) perfect and maintain the validity, effectiveness and priority of any of the Security Documents and any of the Liens created thereunder and (iv) assure, convey, grant, assign, transfer, preserve, protect and confirm more effectively unto the Secured Parties the rights now or hereafter granted to the Secured Parties under any Financing Document or under any other instrument executed in connection with any Financing Document to which any Obligor is a party from time to time.

Section 9.12 Most Favored Lender. If, at any time after the Second Amendment Effective Date, any Material Credit Facility shall be entered into or amended so that it includes any covenant, any event of default (whether set forth as a covenant, undertaking, event of default, restriction, prepayment event or other such provision) or prepayment right not set forth herein or that would be more beneficial to the holders of the Notes than any analogous provision contained in this Agreement (any such covenant, prepayment right or event of default, an “Additional Provision”), then the Company shall provide a Most Favored Lender Notice to the holders of the Notes. Thereupon, such Additional Provision (and any related definitions) shall be deemed automatically incorporated by reference into this Agreement, mutatis mutandis (including any grace period, if applicable, with respect thereto), as if set forth fully herein, without any further action required on the part of any Person, effective as of the date when such Additional Provision became effective under such Material Credit Facility, provided that it shall cease to be effective if, within fifteen (15) days of receipt of such Most Favored Lender Notice by the holders of the Notes, the incorporation of such Additional Provision is waived in writing by the Required Holders. Thereafter upon the request of any holder of a Note, the Company shall enter into any additional agreement or amendment to this Agreement reasonably requested by such holder evidencing any of the foregoing. As used herein, “Most Favored Lender Notice” means, in respect of any Additional Provision, a written notice to each of the holders of the Notes delivered promptly, and in any event within five (5) Business Days after the inclusion of such Additional Provision in any Material Credit Facility (including by way of amendment or other modification of any existing provision thereof), by a Senior Financial Officer of the

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

Company referring to the provisions of this Section 9.12 and setting forth a description of such Additional Provision (including any defined terms used therein) and related explanatory calculations, as applicable. For the avoidance of doubt, upon the incorporation of an Additional Provision herein, an amendment to the relevant Material Credit Facility making such provision, as set forth therein, less beneficial to the creditors under such Material Credit Facility (or the deletion of such provision from such Material Credit Facility) shall not affect such Additional Provision as incorporated in this Agreement, which may only be amended in accordance with Section 17 hereof. For greater certainty, any covenant, event of default or prepayment right in effect under any Material Credit Facility on or before the Second Amendment Effective Date shall not trigger the requirements under this Section 9.12 (it being understood that any amendment thereto after such date would trigger such requirements).

Section 9.13 Equivalent Consideration.

(a) If, at any time after the Second Amendment Effective Date, any Material Credit Facility shall be amended, modified or supplemented, whether directly or indirectly, and the effect of such amendment, modification or supplement shall be to increase the interest rate applicable to any Debt incurred thereunder, then the interest rate applicable to the Notes shall be the interest rate otherwise in effect therefor plus a number of basis points equal to the interest rate increase (expressed in basis points) applicable from time to time to Debt outstanding under such Material Credit Facility as a result of such amendment, modification or supplement. Any such increased interest rate applicable to the Notes shall be effective as of the date of effectiveness of the increased interest rate applicable to such Material Credit Facility and shall remain in effect until the date such increased interest rate shall no longer apply to such Material Credit Facility.

(b) If any fee shall be paid to any lender under any Material Credit Facility solely in its capacity as a lender in excess of, or in addition to, any fee payable to the lenders under the Bank Facility as in effect after the Second Amendment Effective Date, then a pro rata fee shall be paid to each Holder in an amount which bears the same relationship to the principal amount of the Notes held by such Holder as the amount of such excess or such addition bears to the principal amount of the Material Credit Facility held by the Lender to which such excess or addition relates.

(c) If any consideration shall be paid to each lender under a Material Credit Facility solely in its capacity as such (and not, for greater certainty, in any of its capacities as a counterparty under any Swap Contract and not including (i) any withholding tax gross-up payment or other compensatory payment made to a lender on account of any increased costs or reduced returns incurred or suffered by such lender from a change in law, compliance by such lender with regulatory requirements or otherwise; (ii) any extension fee payable to any of the lenders solely in connection with extending the maturity date of such Material Credit Facility; (iii) any increase in any variable rate caused by a change to the underlying prime rate, base rate, London InterBank Offered Rate or equivalent, or (iv) any other amounts payable to any such lender in connection with transactions, advisory services or other services of any kind entered into or provided by such lender to the Company or any Affiliate of the Company where such transactions or services are not directly related to the Material Credit Facility), other than as specified in the foregoing subparagraphs (a) and (b), then the pro rata equivalent of such

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

consideration shall be paid to each holder in an amount which bears the same relationship to the principal amount of the Notes held by such holder as the amount of such consideration bears to the principal amount of the Material Credit Facility held by the lender to which such consideration was paid.

prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

Section 12.3 Rescission. At any time after any Notes have been declared due and payable pursuant to clause (b) or (c) of Section 12.1, the holders of not less than 55% in principal amount of the Notes then outstanding, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by Applicable Law) any overdue interest in respect of the Notes, at the Default Rate, (b) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 17, and (c) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes.

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

or consent pursuant or relating to this Agreement or such Note(s) may be relied upon by the Company for all purposes and shall be binding upon both such beneficial owner and the registered holder. Subject to the preceding sentence, prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to any holder of a Note that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered holders\ of Notes\, and, to the extent set forth in the register, beneficial owners, of Notes. In the event there is a conflict between notices received from a registered holder and a beneficial owner identified in the register, except as provided for in clauses (ii) and (iii) below, the Company may rely for all purposes on the notice first received which shall be binding upon both the beneficial owner and registered holder, regardless of whether such notice is from the registered holder or a beneficial owner, provided that (i) if the notices are received simultaneously, the notice from the registered holder shall govern, (ii) if the notice is in respect of any offer to purchase or prepay Notes pursuant to Section 8, the notice received from the registered holder (or, if no such notice is delivered and a notice from the beneficial owner is delivered, then the notice from the beneficial owner) by the Company within the applicable acceptance period shall be binding upon both the beneficial owner and registered holder and (iii) if the notice is in respect of any offer to purchase or prepay Notes pursuant to Section 8A, the notice received from the registered holder (or, if no such notice is delivered and a notice from the beneficial owner is delivered, then the notice from the beneficial owner) by the Company prior to the Initial Acceptance Date shall be binding upon both the beneficial owner and registered holder.

Section 13.2 Transfer and Exchange of Notes. Upon surrender of any Note at the principal executive office of the Company for registration of transfer or exchange (and in the case of a surrender for registration of transfer, duly endorsed or accompanied by a written instrument of transfer duly executed by the registered holder of such Note or its attorney duly authorized in writing and accompanied by the address for notices of each transferee of such Note or part thereof), within twenty Business Days thereafter, the Company shall execute and deliver, at the Company’s expense (except as provided below), one or more new Notes (as requested by the holder thereof) in exchange therefor, of the series and in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1A-A, Exhibit 1A-B, Exhibit 1A-C, Exhibit 1A-D or Exhibit 1A-E, as applicable. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Notes. Notes shall not be transferred in denominations of less than U.S. $500,000, £500,000 or Can. $500,000, as applicable; provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes of a series, one Note of such series may be in a denomination of less than U.S. $500,000, £500,000 or Can. $500,000, as applicable. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representation set forth in Section 6.2. No transfer, sale, exchange or assignment of a Note shall be deemed to be a discharge, rescission, extinguishment or novation of any Note and any Note so

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

transferred, sold, exchanged or assigned shall continue to be the same obligation of the Company and not a new obligation.

Section 13.3 Replacement of Notes. Upon receipt by the Company of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such Institutional Investor of such ownership and such loss, theft, destruction or mutilation), and

(a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the holder of such Note is, or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least U.S. $\~~50,000,000,~~\50,000,000 (or its equivalent in other currencies), such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or

(b)	in the case of mutilation, upon surrender and cancellation thereof,

within twenty Business Days thereafter, the Company at its own expense shall execute and deliver, in lieu thereof, a new Note dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

Section 14.1 Place of Payment. Subject to Section 14.2, payments of principal, Make-Whole Amount, if any, and interest becoming due and payable on the Notes shall be made in Calgary, Canada at the principal office of the Company in such jurisdiction. The Company may at any time, by notice to each holder of a Note, change the place of payment of the Notes so long as such place of payment shall be either the principal office of the Company in such jurisdiction or the principal office of a bank or trust company in such jurisdiction.

Section 14.2 Home Office Payment. So long as you or your nominee shall be the holder of any Note, and notwithstanding anything contained in Section 14.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, and interest by the method and at the address specified for such purpose below your name in Schedule A, or by such other method or at such other address as you shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, you shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 14.1. The Company will make such payments in immediately available funds, no later than 11:00 a.m. New York, New York time on the date due. If for any reason whatsoever the Company does not make any such payment by such 11:00 a.m. transmittal time, such payment shall be deemed to have been made on the next following Business Day and such payment shall bear interest at the Default Rate set forth in the Note. Prior to any sale or other disposition of any Note held by you or your nominee you will, at your election, either endorse thereon the amount of principal paid

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes of the same series pursuant to Section 13.2. The Company will afford the benefits of this Section 14.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by you under this Agreement and that has made the same agreement relating to such Note as you have made in this Section 14.2.

Section 14.3 Payment Free and Clear of Taxes. (a) Each payment by the Company in respect of the Notes shall be made, under all circumstances, without setoff, counterclaim or reduction for, and free from and clear of, and without deduction for or because of, any and all present or future taxes, levies, imposts, duties, fees, charges, deductions, withholding, restrictions or conditions of any nature whatsoever (hereinafter called “ Relevant Taxes”) imposed, levied, collected, assessed, deducted or withheld by the Government of Canada or any Provincial or other political subdivision of Canada or by the government of any other country or jurisdiction or any authority therein or thereof (other than the United States of America) from or through which payments hereunder or on or in respect of the Notes are actually made (each a “Taxing Jurisdiction”), unless such imposition, levy, collection, assessment, deduction, withholding or other restriction or condition is required by law. If the Company is required by law to make any payment under this Agreement in respect of the Notes subject to such deduction, withholding or other restriction or condition, then the Company shall forthwith (a) pay over to the government or taxing authority imposing such tax the full amount required to be deducted, withheld from or otherwise paid by the Company (including the full amount required to be deducted or withheld from or otherwise paid by the Company in respect of the Tax Indemnity Amounts (as defined below)), and (b) pay each holder of the Notes such additional amounts (“Tax Indemnity Amounts”) as may be necessary in order that the net amount of every payment made to each holder of Notes, after provision for payment of such Relevant Taxes (including any required deduction, withholding or other payment of tax on or with respect to such Tax Indemnity Amounts), shall be equal to the amount which such holder would have received had there been no imposition, levy, collection, assessment, deduction, withholding or other restriction or condition. Notwithstanding the provisions of this Section 14.3, no such Tax Indemnity Amounts shall be payable (i) to any holder of the Notes which is liable for any tax, assessment or other governmental charge by reason of it being or having been effectively connected to Canada for any reason or in any capacity other than solely as a holder of a Note, (ii) for or on account of any tax, assessment or other governmental charge that is imposed or withheld by reason of the failure of the holder of a Note to complete, execute and deliver to the Company any form or document to the extent applicable to such holder that may be required by law or by reason of administration of such law and which is reasonably requested in writing to be delivered by the Company in order to enable the Company to make payments pursuant to this Section 14.3 without deduction or withholding for taxes, assessments or governmental charges, or with deduction or withholding of such lesser amount, which form or document shall be delivered within one hundred twenty (120) days of a written request therefor by the Company, or (iii) in the case where such holder of a Note is not a resident \~~(for~~\within the \~~purposes of the~~ ~~Income Tax~~ ~~Act (Canada)) of Canada,~~\meaning of the United States-Canada Tax Convention (1980) (as amended), the Company shall not be obligated to pay any amount in excess of the amount which the Company would have been obligated to pay hereunder if such holder \~~had~~ ~~been acting at arms’ length for the~~\were resident in the United States of America for purposes of \~~the Income Tax Act (Canada)~~ \such convention. If in connection with the payment of any such Tax Indemnity Amounts, any holder of the Notes that is a United States person within the

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

meaning of the Code, a United Kingdom person within the meaning of the Inland Revenue tax code or a foreign person engaged in a trade or business within the United States of America or the United Kingdom, incurs taxes imposed by the United States of America, the United Kingdom or any political subdivision or taxing authority therein on such Tax Indemnity Amounts, the Company shall pay to such holder of the Notes such further amount as will insure that the net amount actually received by that holder of the Notes (taking into account any withholding or deduction in respect of any such further amount) is equal to the amount which such holder of the Notes would have received had such withholding or deduction not been made.

(b) If the Company makes payment of Tax Indemnity Amounts and a recipient thereof subsequently receives a cash refund in respect thereof from the governmental body to which the Relevant Taxes giving rise to the Tax Indemnity Amount were paid (a “Tax Refund”), and such recipient is able to identify the Tax Refund as being attributable to the Relevant Taxes with respect to which the Tax Indemnity Amounts are paid, then such recipient shall, to the extent that it can do so without prejudice to the retention of the amount of such Tax Refund or the right of such recipient to obtain any other relief or allowance available to it, reimburse the Company such amount as it shall determine to be the proportion of the Tax Refund as will leave such recipient, after the reimbursement, in no worse position than such recipient would have been in if payment of the Tax Indemnity Amounts had not been required. Such recipient may charge to the Company (and may deduct from amounts reimbursable to the Company hereunder) a fee reasonably determined by such recipient to compensate it for any additional effort expended or cost incurred in determining such credit or remission or allocating it to the Company. The foregoing notwithstanding, nothing in this Section 14.3 shall restrict the right of any recipient to arrange its tax affairs as it shall think fit or require any recipient to disclose any information regarding its tax affairs or any computation pursuant hereto which, in such recipient’s judgment, constitutes confidential information.

(a) U.S. Dollar Notes. Any payment made by the Company to any holder of the U.S. Dollar Notes or for the account of any such holder in respect of any amount payable by the Company hereunder or under the U.S. Dollar Notes shall be made in U.S. Dollars. Any amount received or recovered by such holder other than in U.S. Dollars (whether as a result of, or of the enforcement of, a judgment or order of any court, or in the liquidation or dissolution of the Company or otherwise) in respect of any such sum expressed to be due hereunder or under the U.S. Dollar Notes shall constitute a discharge of the Company only to the extent of the amount of U.S. Dollars which such holder is able, in accordance with normal banking procedures, to purchase with the amount so received or recovered in that other currency on the date of the receipt or recovery (or, if it is not practicable to make that purchase on such date, on the first date on which it is practicable to do so). If the amount of U.S. Dollars so purchased is less than the amount of U.S. Dollars expressed to be due hereunder or under the U.S. Dollar Notes, the Company shall indemnify such holder in U.S. Dollars against any loss sustained by such holder as a result, and in any event, the Company shall indemnify such holder against the cost of making any such purchase. These indemnities shall constitute a separate and independent obligation from the other obligations herein and in the U.S. Dollar Notes, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by any such holder, shall continue in full force and effect despite any judgment, order, claim or proof for a liquidated amount in respect of any such sum due hereunder and under any U.S. Dollar Note or any judgment or order and shall survive the payment of the U.S. Dollar Notes and the termination of this Agreement.

(b) Pounds Sterling Notes. Any payment made by the Company to any holder of the Pounds Sterling Notes or for the account of any such holder in respect of any amount payable by the Company hereunder or under the Pounds Sterling Notes shall be made in Pounds Sterling. Any amount received or recovered by such holder other than in Pounds Sterling (whether as a result of, or of the enforcement of, a judgment or order of any court, or in the liquidation or dissolution of the Company or otherwise) in respect of any such sum expressed to be due hereunder or under the Pounds Sterling Notes shall constitute a discharge of the Company only to the extent of the amount of Pounds Sterling which such holder is able, in accordance with normal banking procedures, to purchase with the amount so received or recovered in that other currency on the date of the receipt or recovery (or, if it is not practicable to make that purchase on such date, on the first date on which it is practicable to do so). If the amount of Pounds Sterling so purchased is less than the amount of Pounds Sterling expressed to be due hereunder or under the Pounds Sterling Notes, the Company shall indemnify such holder in Pounds Sterling against any loss sustained by such holder as a result, and in any event, the Company shall indemnify such holder against the cost of making any such purchase. These indemnities shall constitute a separate and independent obligation from the other obligations herein and in the Pounds Sterling Notes, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by any such holder, shall continue in full force and effect despite any judgment, order, claim or

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

(ii) the Company, or any of the\ ~~Restricted~~\ Subsidiaries adopts a material change in an accounting policy in order to more appropriately present events or transactions in its financial statements;

and in either case the above change would require disclosure under GAAP in the consolidated financial statements of the Company and would cause an amount required to be determined for the purposes of a financial covenant under Section 10.1, \ ~~10.2~~, \10.3,\ ~~10.4~~\ or 10.5 or otherwise (a “Financial Covenant”) to be materially different than the amount that would be determined without giving effect to such change, the Company shall notify each holder of such change (an “Accounting Change”). Such notice (an “Accounting Change Notice”) shall describe the nature of the Accounting Change, its effect or anticipated effect on the current and immediately prior year’s financial statements in accordance with GAAP and state whether the Company desires to revise the method of calculating one or more of the Financial Covenants (including the revision of any of the defined terms used in the determination of such Financial Covenant) in order that amounts determined after giving effect to such Accounting Change and the revised method of calculating such Financial Covenant will approximate the amount that would be determined without giving effect to such Accounting Change and without giving effect to the revised method of calculating such Financial Covenant. The Accounting Change Notice shall be delivered to the holders within 60 days of the end of the fiscal quarter in which the Accounting Change is implemented or, if such Accounting Change is implemented in the fourth fiscal quarter or in respect of an entire fiscal year, within 120 days of the end of such period.

If, pursuant to the Accounting Change Notice, the Company does not indicate that it desires to revise the method of calculating one or more of the Financial Covenants, the Required Holders may, within 45 days of receipt of the date of the Accounting Change Notice, notify the Company that they wish to revise the method of calculating one or more of the Financial Covenants in the manner described above.

If either the Company or the Required Holders so indicate that they wish to revise the method of calculating one or more of the Financial Covenants, the Company and the Required Holders shall in good faith attempt to agree on a revised method of calculating the Financial Covenants. If, however, within 120 days of the foregoing notice by the Company or the Required Holders of their desire to revise the method of calculating one or more of the Financial Covenants, the Company and the Required Holders have not reached agreement in writing on such revised method of calculation, such method of calculation shall not be revised and all amounts to be determined thereunder shall be determined without giving effect to the Accounting Change. For greater certainty, if no notice of a desire to revise the method of calculating the Financial Covenants in respect of an Accounting Change is given by either the Company or the Required Holders within the applicable time period described above, the method of calculating the Financial Covenants shall not be revised in response to such Accounting Change and all amounts to be determined pursuant to the Financial Covenants shall be determined after giving effect to such Accounting Change.

If a certificate is delivered pursuant to Section 7.2 in respect of a fiscal quarter or fiscal year in which an Accounting Change is implemented without giving effect to any revised method of calculating any of the Financial Covenants, and subsequently, as provided above, the method of calculating one or more of the Financial Covenants is revised in response to such

\~~Pengrowth Energy Corporation Note Purchase Agreement~~\

Accounting Change, or the amounts to be determined pursuant to any of the Financial Covenants are to be determined without giving effect to such Accounting Change, the Company shall deliver within 30 days of such revision a revised certificate in accordance with Section 7.2. Any Default or Event of Default arising as a result of the Accounting Change and which is cured by this Section 22.10 shall be deemed to be of no effect ab initio.

Section 22.11 Severability. Any provision of this Agreement 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 (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

Section 22.12 Construction. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

Section 22.13 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

Section 22.14 Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the Province of Alberta and the laws of Canada applicable therein.

Section 22.15 Submission to Jurisdiction. The Company agrees that the courts of Alberta shall have jurisdiction to hear and determine any suit, action or proceeding and to settle any disputes which may arise out of or in connection with the aforesaid documents and it irrevocably submits to the non-exclusive jurisdiction of such courts, without prejudice to the rights of any holder of a Note to take proceedings in any other jurisdictions, whether concurrently or not. The Company agrees that final judgment in any such suit, action or proceeding brought in such courts shall be conclusive and binding upon it and may be enforced against it in the courts of Canada (or any other courts to the jurisdiction of which it or its property is subject) by a suit upon such judgment, provided that it does not waive any right to appeal any such judgment, to seek any stay or otherwise to seek reconsideration or review of any such judgment.

Section 22.16 Exchange Rate. For the purpose of (a) determining the percentage ownership of Notes under the definition of “Required Holders”\ or\, (b) determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent given under this Agreement or the Notes, or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes

Dollar~~\U.S. Dollar Notes, Pounds Sterling Notes or 2010 Notes shall be deemed to be the Canadian Dollar equivalent of the principal amount \~~in U.S. Dollars calculated on the basis of an exchange rate of~~ 1.00 Cdn. Dollars to 1.00 U.S. Dollar and the principal amount of any outstanding Pounds Sterling Notes shall be deemed to be the equivalent amount in U.S. Dollars calculated on the basis of an exchange rate of 0.62 Pounds Sterling to 1.00 U.S. Dollars.\of each Note or 2010 Note, calculated based on the daily average exchange rate quoted by the Bank of Canada at approximately the close of business on the Business Day which is two (2) Business Days prior to the date set for such computation pursuant to the foregoing clauses (a) through (c), and if no such rate is quoted, the spot rate of exchange quoted by the Bank Agent in Toronto, Ontario at approximately noon (Toronto time) on the Business Day which is (2) Business Days prior to the date set for computation in accordance with its normal practice or, if such date of computation is not a Business Day, on the Business Day immediately preceding such date.

If the \~~Guarantors are~~\Guarantor is required by law to make any payment under this Guaranty subject to such deduction, withholding or other restriction or condition, then the \~~Guarantors~~\Guarantor shall forthwith (a) pay over to the government or taxing authority imposing such tax the full amount required to be deducted, withheld from or otherwise paid by the \~~Guarantors~~\Guarantor (including the full amount required to be deducted or withheld from or otherwise paid by the \~~Guarantors~~\Guarantor in respect of the Tax Indemnity Amounts (as defined below)), and (b) pay each holder of the Notes such additional amounts (“Tax Indemnity Amounts”) as may be necessary in order that the net amount of every payment made to each holder of Notes, after provision for payment of such Relevant Taxes (including any required deduction, withholding or other payment of tax on or with respect to such Tax Indemnity Amounts), shall be equal to the amount which such holder would have received had there been no imposition, levy, collection, assessment, deduction, withholding or other restriction or condition. Notwithstanding the provisions of this Section 12.3, no such Tax Indemnity Amounts shall be payable (i) to any holder of the Notes which is liable for any tax, assessment or other governmental charge by reason of it being or having been effectively connected to Canada for any reason or in any capacity other than solely as a holder of a Note, (ii) for or on account of any tax, assessment or other governmental charge that is imposed or withheld by reason of the failure of the holder of a Note to complete, execute and deliver to the \~~Guarantors~~\ Guarantor any form or document to the extent applicable to such holder that may be required by law or by reason of administration of such law and which is reasonably requested in writing to be delivered by the \~~Guarantors~~\Guarantor in order to enable the \~~Guarantors~~\Guarantor to make payments pursuant

to this Section 12.3 without deduction or withholding for taxes, assessments or governmental charges, or with deduction or withholding of such lesser amount, which form or document shall be delivered within one hundred twenty (120) days of a written request therefor by the \~~Guarantors~~\ Guarantor, or (iii) in the case where such holder of a Note is not a resident (for the purposes of the Income Tax Act (Canada)) of Canada, in excess of the amount which the \~~Guarantors~~\Guarantor would have been obligated to pay hereunder if such holder had been acting at arms’ length for the purposes of the Income Tax Act (Canada). If in connection with the payment of any such Tax Indemnity Amounts, any holder of the Notes that is a United States person within the meaning of the Code, a United Kingdom person within the meaning of the Inland Revenue tax code or a foreign person engaged in a trade or business within the United States of America or the United Kingdom, incurs taxes imposed by the United States of America, the United Kingdom or any political subdivision or taxing authority therein on such Tax Indemnity Amounts, the \~~Guarantors~~\Guarantor shall pay to such holder of the Notes such further amount as will insure that the net amount actually received by that holder of the Notes (taking into account any withholding or deduction in respect of any such further amount) is equal to the amount which such holder of the Notes would have received had such withholding or deduction not been made.

(b) If the \~~Guarantors make~~ \Guarantor makes payment of Tax Indemnity Amounts and a recipient thereof subsequently receives a cash refund in respect thereof from the governmental body to which the Relevant Taxes giving rise to the Tax Indemnity Amount were paid (a “Tax Refund”), and such recipient is able to identify the Tax Refund as being attributable to the Relevant Taxes with respect to which the Tax Indemnity Amounts are paid, then such recipient shall, to the extent that it can do so without prejudice to the retention of the amount of such Tax Refund or the right of such recipient to obtain any other relief or allowance available to it, reimburse the \~~Guarantors~~\Guarantor such amount as it shall determine to be the proportion of the Tax Refund as will leave such recipient, after the reimbursement, in no worse position than such recipient would have been in if payment of the Tax Indemnity Amounts had not been required. Such recipient may charge to the \~~Guarantors~~\ Guarantor (and may deduct from amounts reimbursable to the \~~Guarantors~~\ Guarantor hereunder) a fee reasonably determined by such recipient to compensate it for any additional effort expended or cost incurred in determining such credit or remission or allocating it to the \~~Guarantors~~\Guarantor.
