Re: Offering of 5.0% Unsecured Subordinated Convertible Debentures of Advantage Oil & Gas Ltd.

RBC Dominion Securities Inc., BMO Nesbitt Burns Inc., National Bank Financial Inc., Scotia Capital Inc., CIBC World Markets Inc., FirstEnergy Capital Corp., Thomas Weisel Partners Canada Inc., HSBC Securities (Canada) Inc., and Macquarie Capital Markets Canada Ltd. (collectively, the "Underwriters") understand that Advantage Oil & Gas Ltd. (the "Corporation" or "Advantage") proposes to issue and sell 75,000 unsecured subordinated convertible debentures with a face value of $1,000 principal amount per Firm  Debenture (as defined below), a coupon of 5.0% per annum, payable semi-annually in arrears on January 31 and July 31 of each year commencing July 31, 2010 and a maturity date of January 30, 2015 (the "Maturity Date"), subject to redemption at the option of the Corporation in certain circumstances, subsequent to January 31, 2013, as set forth in the Prospectus (as defined below) and the Debenture Indenture (as defined below) (the "Firm Debentures").  The Firm Debentures shall be convertible into Common Shares (as defined below)  at an initial conversion price of $8.60 per Common Share at any time prior to the close of business on the earlier of (i)  the Business Day (as defined below) immediately preceding the Maturity Date or, (ii) if called for redemption, the Business Day immediately preceding the date specified by the Corporation for redemption of the Firm Debentures, or (iii)  if called for repurchase pursuant to a Change of Control (as such term is defined in the Debenture Indenture), on the Business Day immediately preceding the payment date, subject to adjustment in certain circumstances, and shall otherwise have such attributes as are described in the Prospectus.

The Underwriters further understand that the Corporation plans to use the net proceeds from the offering of the Firm Debentures to initially repay indebtedness under Advantage's credit facilities which may be subsequently redrawn to fund capital expenditures and for general corporate purposes.

Subject to the terms and conditions hereof, the Underwriters hereby severally, and not jointly, agree to purchase from the Corporation the Firm Debentures at the Closing Time (as hereinafter defined) in the respective percentages set forth in paragraph 18, and the Corporation hereby agrees to issue and sell to the Underwriters at the Closing Time all, but not less than all, of the Firm Debentures at the price of $1,000 for each of the Firm Debentures for an aggregate purchase price of $75,000,000.

The Corporation hereby grants to the Underwriters an option (the "Over-Allotment Option") to purchase, at the Underwriters' election, exercisable in whole or in part at any time and from time to time up to 30 days following the Closing Time, up to 11,250 additional debentures (the "Over-Allotment Debentures") from the Corporation for the purpose of covering over-allotments, if any, and for market stabilization purposes.  In the event and to the extent that the Underwriters exercise the Over-Allotment Option, subject to the terms and conditions hereof, the Underwriters hereby severally, and not jointly agree to purchase from the Corporation the number of Over-Allotment Debentures as to which the Over-

Allotment Option shall have been exercised in the respective percentages set forth in paragraph 18 hereof, and the Corporation, hereby agrees to issue and sell such number of Over-Allotment Debentures to the Underwriters at the purchase price of $1,000 per Over Allotment Debenture.

After the Underwriters have made a reasonable effort to sell the Offered Securities (as defined herein) at the initial offering price of $1,000 per Offered Security specified herein, the offering price may be decreased, and further changed, from time to time, to an amount not greater than the initial offering price specified herein in accordance with the procedures permitted by NI 44-101 (as defined herein) and the compensation realized by the Underwriters will be decreased by the amount that the aggregate price paid by the purchasers for the Offered Securities is less than the gross proceeds paid by the Underwriters to the Corporation.

- 16 -

(i) any information or statement contained in or incorporated by reference into the Preliminary Prospectus, the Prospectus, any Supplementary Material or in any other document or material filed or delivered pursuant hereto (other than any information or statement relating solely to the Underwriters and furnished to the Corporation by the Underwriters or the Underwriters' counsel expressly for inclusion in the Preliminary Prospectus or Prospectus) which is or is alleged to be untrue or any omission or alleged omission to provide any information or state any fact (other than any information or fact relating solely to the Underwriters) the omission of which makes or is alleged to make any such information or statement untrue or misleading in light of the circumstances in which it was made;

(ii) any misrepresentation or alleged misrepresentation (except a misrepresentation which is based upon information relating solely to the Underwriters and furnished to the Corporation by the Underwriters or the Underwriters' counsel, as the case may be, expressly for inclusion in the Preliminary Prospectus or Prospectus) contained in or incorporated by reference into the Preliminary Prospectus, the Prospectus, any Supplementary Materials or in any other document or any other part of the Public Record filed by or on behalf of the Trust or the Corporation;

(iii) any prohibition or restriction of trading in the securities of the Corporation or any prohibition or restriction affecting the distribution of the Offered Securities imposed by any competent authority (not based on the activities or alleged activities of the Underwriters or their banking or Selling Dealer Group members, if any) if such prohibition or restriction is based on any misrepresentation or alleged misrepresentation of a kind referred to in subparagraph 8(a)(ii);

(iv) any order made or any inquiry, investigation (whether formal or informal) or other proceeding commenced or threatened by any one or more competent authorities (not based upon the activities or the alleged activities of the Underwriters or their banking or Selling Dealer Group members, if any) prohibiting, restricting, relating to or materially affecting the trading or distribution of the Offered Securities; or

provided, however, no party who has engaged in any fraud, wilful misconduct, fraudulent misrepresentation or negligence shall be entitled, to the extent that the liabilities, claims, losses, costs, damages or expenses were caused by such activity, to claim indemnification from any person who has not engaged in such fraud, wilful misconduct, fraudulent misrepresentation or negligence (provided that, for greater certainty, the foregoing shall not disentitle an Underwriter from claiming indemnification hereunder to the extent that the negligence, if any, relates to the Underwriter's failure to conduct adequate "due diligence").

- 17 -

(b) If any claim contemplated by paragraph 8(a) shall be asserted against any of the persons or corporations in respect of which indemnification is or might reasonably be considered to be provided for in such paragraphs, such person or corporation (the "Indemnified Person") shall notify the Corporation (the "Indemnifying Party") (provided that failure to so notify the Indemnifying Party of the nature of such claim in a timely fashion shall relieve the Indemnifying Party of liability hereunder only if and to the extent that such failure materially prejudices the Indemnifying Party's ability to defend such claim) as soon as possible of the nature of such claim and the Indemnifying Party shall be entitled (but not required) to assume the defence of any suit brought to enforce such claim, provided however, that the defence shall be through legal counsel selected by the Indemnifying Party and acceptable to the Indemnified Person acting reasonably and that no settlement or admission of liability may be made by the Indemnifying Party or the Indemnified Person without the prior written consent of the other, such consent not to be unreasonably withheld.  The Indemnified Person shall have the right to retain its own counsel in any proceeding relating to a claim contemplated by paragraph 8(a) if:

(i) the Indemnified Person has been advised by counsel that there may be a reasonable legal defense available to the Indemnified Person which is different from or additional to a defense available to an Indemnifying Party and that representation of the Indemnified Person and the Indemnifying Party by the same counsel would be inappropriate due to the actual or potential differing interests between them (in which case the Indemnifying Party shall not have the right to assume the defense of such proceedings on the Indemnified Person's behalf);

(ii) the Indemnifying Party shall not have taken the defense of such proceedings and employed counsel within ten (10) days after notice has been given to the Indemnifying Party of commencement of such proceedings; or

(iii) the employment of such counsel has been authorized by the Indemnifying Party in connection with the defense of such proceedings;

and, in any such event, the reasonable fees and expenses of such Indemnified Person's counsel (on a solicitor and his client basis) shall be paid by the Indemnifying Party, provided that the Indemnifying Party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate law firm (in addition to any local counsel) for all such Indemnified Persons.

(c) The Indemnifying Party hereby waives its rights to recover contribution from the Underwriters with respect to any liability of the Indemnifying Party by reason of or arising out of any misrepresentation in the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record provided, however, that such waiver shall not apply in respect of liability caused or incurred by reason of any misrepresentation which is based upon information relating solely to the Underwriters contained in such document and furnished to the Corporation by the Underwriters expressly for inclusion in the Preliminary Prospectus or the Prospectus.

- 18 -

(d) If any legal proceedings shall be instituted against an Indemnifying Party in respect of the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record, or if any regulatory authority or stock exchange shall carry out an investigation of an Indemnifying Party in respect of the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record, and, in either case, any Indemnified Person is required to testify, or respond to procedures designed to discover information, in connection with or by reason of the services performed by the Underwriters hereunder, the Indemnified Persons may employ their own legal counsel and the Indemnifying Party shall pay and reimburse the Indemnified Persons for the reasonable fees, charges and disbursements (on a full indemnity basis) of such legal counsel, the other expenses reasonably incurred by the Indemnified Persons in connection with such proceedings or investigation and a fee at the normal per diem rate for any director, officer or employee of the Underwriters involved in the preparation for or attendance at such proceedings or investigation.

(e) The rights and remedies of the Indemnified Persons set forth in paragraphs 8, 9 and 10 hereof are to the fullest extent possible in law cumulative and not alternative and the election by any Underwriter or other Indemnified Person to exercise any such right or remedy shall not be, and shall not be deemed to be, a waiver of any other rights and remedies.

(f) The Indemnifying Party hereby acknowledges that the Underwriters are acting as agents for the Underwriters' respective agents, directors, officers, shareholders and employees under this paragraph 8 and under paragraph 9 with respect to all such agents, directors, officers, shareholders and employees.

(g) The Indemnifying Party waives any right it may have of first requiring an Indemnified Person to proceed against or enforce any other right, power, remedy or security or claim or to claim payment from any other person before claiming under this indemnity.  It is not necessary for an Indemnified Person to incur expense or make payment before enforcing such indemnity.

(h) The rights of indemnity contained in this paragraph 8 shall not apply if the Indemnifying Party has complied with the provisions of paragraphs 3 and 4 and the person asserting any claim contemplated by this paragraph 8 was not provided with a copy of the Prospectus or any amendment to the Prospectus or other document which corrects any misrepresentation or alleged misrepresentation which is the basis of such claim and which was required, under Applicable Securities Laws, to be delivered to such person by the Underwriters.

(i) If the Indemnifying Party has assumed the defense of any suit brought to enforce a claim hereunder, the Indemnified Person shall provide the Indemnifying Party copies of all documents and information in its possession pertaining to the claim, take all reasonable actions necessary to preserve its rights to object to or defend against the claim, consult and reasonably cooperate with the Indemnifying Party in determining whether the claim and any legal proceeding resulting therefrom should be resisted, compromised or settled and reasonably cooperate and assist in any negotiations to compromise or settle, or in any defense of, a claim undertaken by the Indemnifying Party.

9. Contribution

In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this agreement is due in accordance with its terms but is, for any reason, held by a court to be unavailable from the Indemnifying Party on grounds of policy or otherwise, the Indemnifying Party and the party or parties seeking indemnification shall contribute to the aggregate liabilities, claims, demands, losses (other than losses of profit in connection with the distribution of the Offered Securities), costs (including, without limitation, reasonable legal fees and disbursements on a full indemnity basis), damages and expenses to which they may be subject or which they may suffer or incur:

(a) in such proportion as is appropriate to reflect the relative benefit received by the Indemnifying Party on the one hand, and by the Underwriters on the other hand, from the offering of the Offered Securities; or

(b) if the allocation provided by paragraph 9(a) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in paragraph 9(a) above but also to reflect the relative fault of the Underwriters on the one hand, and the Indemnifying Party, on the other hand, in connection with the statements, commissions or omissions or other matters which resulted in such liabilities, claims, demands, losses, costs, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Indemnifying Party, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion that the total proceeds of the offering received by the Indemnifying Party (net of fees but before deducting expenses) bear to the fees received by the Underwriters.  In the case of liability arising out of the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record, the relative fault of the Indemnifying Party, on the one hand, and of the Underwriters, on the other hand, shall be determined by reference, among other things, to whether the misrepresentation or alleged misrepresentation, order, inquiry, investigation or other matter or thing referred to in paragraph 8 relates to information supplied or which ought to have been supplied by, or steps or actions taken or done on behalf of or which ought to have been taken or done on behalf of the Indemnifying Party or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such misrepresentation or alleged misrepresentation, order, inquiry, investigation or other matter or thing referred to in paragraph 8.

The amount paid or payable by an Indemnified Person as a result of liabilities, claims, demands, losses (other than losses of profit in connection with the distribution of the Offered Securities), costs, damages and expenses (or claims, actions, suits or proceedings in respect thereof) referred to above shall, without limitation, include any legal or other expenses reasonably incurred by the Indemnified Person in connection with investigating or defending such liabilities, claims, demands, losses, costs, damages and expenses (or claims, actions, suits or proceedings in respect thereof) whether or not resulting in any action, suit, proceeding or claim.

The Indemnifying Party and the Underwriters agree that it would not be just and equitable if contributions pursuant to this agreement were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to in the immediately preceding paragraphs.  The rights to contribution provided in this paragraph 9 shall be in addition to, and without prejudice to, any other right to contribution which the Underwriters or other Indemnified Persons may have.

- 20 -

Any liability of the Underwriters under this paragraph 9 shall be limited to the amount actually received by the Underwriters under paragraph 2.

(c) Any termination pursuant to the terms of this agreement shall be effected by notice in writing delivered to the Corporation and the other Underwriters, provided that no termination shall discharge or otherwise affect any obligation of the Corporation under paragraphs 8, 9, 10 or 16.  The rights of the Underwriters to terminate their obligations hereunder are in addition to, and without prejudice to, any other remedies they may have.

(d) If an Underwriter elects to terminate its obligation to purchase the Offered Securities as aforesaid, whether the reason for such termination is within or beyond the control of the Corporation, the liability of the Corporation hereunder shall be limited to the indemnity referred to in paragraph 8, the contribution rights referred to in paragraph 9 and the payment of expenses referred to in paragraph 10; provided, however, an Underwriter shall not be entitled to the payment of expenses referred to in paragraph 10 if an Underwriter is in breach of or default under or non-compliance with any representation, warranty, term or condition of this Agreement, in any material respect.

(b) if an Underwriter (a "Refusing Underwriter") does not complete the purchase and sale of the Offered Securities which that Underwriter has agreed to purchase under this Agreement (other than in accordance with paragraph 11) (the "Defaulted Securities"), the remaining Underwriters (the "Continuing Underwriters") will be entitled, at their option, to purchase all but not less than all of the Defaulted Securities pro rata according to the number of Offered Securities to have been acquired by the Continuing Underwriters under this Agreement or in any proportion agreed upon, in writing, by the Continuing Underwriters.  If no such arrangement has been made and the number of Defaulted Securities to be purchased by the Refusing Underwriter(s) does not exceed 6% of the Offered Securities, the Continuing Underwriters will be obligated to purchase the Defaulted Securities on the terms set out in this Agreement in proportion to their obligations under this Agreement.  If the number of Defaulted Securities to be purchased by the Refusing Underwriters exceeds 6% of the Offered Securities, the Continuing Underwriters will not be obligated to purchase the Defaulted Securities and, if the Continuing Underwriters do not elect to purchase the Defaulted Securities:

(e) as soon as reasonably practicable after the Closing Date provide the Corporation with a break down in writing of the number of Offered Securities sold in each of the Qualifying Provinces and, upon completion of the distribution of the Offered Securities, provide to the Corporation, the Exchanges and to the Securities Commissions prompt notice in writing to that effect.

21. Severance

If one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this agreement, but this agreement shall be construed as if such invalid, illegal or unenforceable provision or provisions had never been contained herein.

23. Stabilization

In connection with the distribution of the Offered Securities, the Underwriters may over-allot or effect transactions which stabilize or maintain the market price of the securities of the Corporation at levels other than those which might otherwise prevail in the open market, but in each case only as permitted by Applicable Securities Laws.  Such stabilizing transactions, if any, may be discontinued at any time.

25. Time of the Essence

Time shall be of the essence of this agreement.
