9

Registration Statement, the General Disclosure Package or the Final Prospectus, together with any amendment or supplement thereto used by the Company or any Underwriter, as the case may be, it being understood that the only such information furnished by the Selling Stockholder consists of the information relating to such Selling Stockholder in the Registration Statement, the General Disclosure Package and the Final Prospectus under the heading “Selling Stockholder” and the footnote thereunder, excluding any percentages set forth therein (the “Selling Stockholder Information”).

(h)                                 No Finder’s Fee. Except as disclosed in the General Disclosure Package and the Final Prospectus, there are no contracts, agreements or understandings between the Selling Stockholder and any person that would give rise to a valid claim against the Company or any Underwriter for a brokerage commission, finder’s fee or other like payment in connection with the sale of the Offered Securities.

(i)                                     Absence of Manipulation. The Selling Stockholder has not taken, directly or indirectly, any action that is designed to or that has constituted or that would reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Offered Securities.

(j)                                    Lock-Up Agreement. On or prior to the date hereof, the Selling Stockholder has executed and delivered to the Underwriters an agreement substantially in the form set forth in Annex B hereto.  Such agreement has been duly authorized, executed and delivered by the Selling Stockholder and constitutes the valid and legally binding obligation of the Selling Stockholder, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

4.                                      Purchase, Sale and Delivery of Offered Securities.  On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, the Selling Stockholder agrees to sell to the several Underwriters, the Firm Securities, and each of the Underwriters agrees, severally and not jointly, to purchase from the Selling Stockholder, at a purchase price of $28.32 per share, the respective number of shares of Firm Securities set forth opposite the names of the Underwriters in Schedule A hereto.

At 9:00 am (Central time) on February 6, 2013, or at such other time not later than seven full business days thereafter as Credit Suisse and the Company determine (such time being herein referred to as the “First Closing Date”), the Selling Stockholder will deliver the Firm Securities to the Representatives at the office of Latham & Watkins LLP, Houston, Texas (the “Closing Location”), counsel for the Underwriters, or through the facilities of DTC, in either case for the accounts of the several Underwriters, against payment of the purchase price therefor by the Underwriters in Federal (same day) funds by wire transfer to an account at a bank designated by the Selling Stockholder to the Representatives prior to the First Closing Date.  For purposes of Rule 15c6-1 under the Exchange Act, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to this Agreement. A meeting will be held at the Closing Location at or about 5:00 p.m., New York City time, on the business day next preceding such First Closing Date, at which meeting the final drafts of the documents to be delivered pursuant to this Agreement will be available for review by the parties hereto.

From time to time not more than 30 days subsequent to the date of the Final Prospectus, the Underwriters may purchase all or less than all of the Optional Securities at the purchase price per Security to be paid for the Firm Securities, upon written notice from Credit Suisse given to the Selling Stockholder and the Company setting forth the aggregate number of shares of Optional Securities as to which the Underwriters are exercising the option and the time and place at which such Optional Securities will be delivered.  The Selling Stockholder agrees to sell to the

10

Underwriters the number of shares of Optional Securities specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Securities.  Such Optional Securities shall be purchased for the account of each Underwriter in the same proportion as the number of shares of Firm Securities set forth opposite such Underwriter’s name bears to the total number of shares of Firm Securities (subject to adjustment by Credit Suisse to eliminate fractions). No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by Credit Suisse to the Selling Stockholder.

Each time for the delivery of and payment for the Optional Securities, being herein referred to as an “Optional Closing Date”, which may be the First Closing Date (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”), shall be determined by Credit Suisse but shall be not later than five full business days after written notice of election to purchase Optional Securities is given to the Selling Stockholder and the Company. The Selling Stockholder will deliver the Optional Securities being purchased on each Optional Closing Date to the Representatives at the office of Latham & Watkins LLP, Houston, Texas, counsel for the Underwriters, or through the facilities of DTC, in either case for the accounts of the several Underwriters, against payment of the purchase price therefor by the Underwriters in Federal (same day) funds by wire transfer to an account at a bank designated by the Selling Stockholder to the Representatives prior to each such Optional Closing Date.  A meeting will be held at the Closing Location at or about 5:00 p.m., New York City time, on the business day next preceding such Optional Closing Date, at which meeting the final drafts of the documents to be delivered pursuant to this Agreement will be available for review by the parties hereto.

5.                                      Offering by Underwriters.  It is understood that the several Underwriters propose to offer the Offered Securities for sale to the public as set forth in the Final Prospectus.

(b)                                 Filing of Amendments; Response to Commission Requests.  The Company will promptly advise the Representatives of any proposal to amend or supplement the Registration Statement or any Statutory Prospectus at any time and will offer the Representatives a reasonable opportunity to comment on any such amendment or supplement; and the Company will also advise the Representatives promptly of (i) the filing of any such amendment or supplement, (ii) any request by the Commission or its staff for any amendment to the Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iii) the institution by the Commission of any stop order proceedings in respect of the Registration Statement or the threatening of any proceeding for that purpose, and (iv) the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose.  The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(c)                                  Continued Compliance with Securities Laws.  If, at any time when a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will promptly notify the Representatives of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriters and the dealers and any other dealers upon request of the Representatives, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.  Neither the Representatives’ consent to, nor the Underwriters’

11

delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 8 hereof.

(d)                                 Rule 158.  As soon as practicable, but not later than 16 months, after the date hereof, the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the date hereof and satisfying the provisions of Section 11(a) of the Act and Rule 158.

The Company shall use its reasonable best efforts to furnish the Final Prospectus on or prior to 3:00 P.M., New York time, on the business day following the execution and delivery of this Agreement. All other such documents shall be so furnished as soon as available. The Company will pay the expenses of printing and distributing to the Underwriters all such documents.

(f)                                   Blue Sky Qualifications.  The Company will arrange for the qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representatives designate and will continue such qualifications in effect so long as required for the distribution; provided, that in connection therewith, the Company will not be required to file a general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it would not otherwise be required to so file or qualify, or subject itself to taxation for doing business in any jurisdiction in which it is not otherwise so subject.

(g)                                  Reporting Requirements.  During the period of five years hereafter, the Company will furnish to the Representative and, upon request, to each of the other Underwriters, as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year; and the Company will furnish to the Representatives (i) as soon as available, a copy of each report and any definitive proxy statement of the Company filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from time to time, such other information concerning the Company as the Representatives may reasonably request.  However, so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”) or such materials as otherwise posted on the Company’s website, it is not required to furnish such reports or statements to the Underwriters.

(h)                                 Payment of Expenses.  The Company agrees with the several Underwriters that the Company will pay all expenses incident to the performance of the obligations of the Company and the Selling Stockholder under this Agreement, including but not limited to (i) any documented filing fees and reasonable attorney’s fees and expenses incurred by the Company or the Underwriters in connection with qualifying or registering (or obtaining exemptions from the qualification or registration of) all or any part of the Offered Securities for offer and sale under the state securities or blue sky laws of such jurisdictions as the Representatives designate and the preparation and printing of memoranda relating thereto, (ii) the documented filing fees incident to, and the reasonable fees and expenses of counsel for the Underwriters, in connection with the FINRA’s review and approval of the Underwriters’ participation in the offering and distribution of the Offered Securities, provided, however, that the Underwriters agree that the maximum amount reimbursable for expenses advanced by the Underwriters shall be $50,000, (iii) costs and expenses relating to investor presentations or any “road show” in connection with the offering and sale of the Offered Securities including, without limitation, any travel expenses of the Company’s officers and employees, provided, however, that the Underwriters will pay for 50% of the costs and expenses of any chartered flight, except for flights on which there is no representative of the Representatives, (iv) fees and expenses incident to listing the Offered Securities on the New York Stock Exchange, (v) fees and expenses in connection with the registration of the Offered Securities under the Exchange Act, (vi) any transfer taxes on the sale by the Selling Stockholder of the Offered Securities to the Underwriters, (vii) expenses incurred in distributing preliminary prospectuses and the Final Prospectus (including any amendments and supplements thereto) to the Underwriters and expenses incurred in preparing, printing and distributing any Issuer Free Writing Prospectuses to investors or prospective investors and (viii) all other fees, costs and expenses referred to in Item 14 of Part II of the Registration Statement.  Except as provided in this Agreement, the Underwriters shall pay their own expenses, including the fees

(i)                                     Absence of Manipulation — Company.  The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Offered Securities.

(k)                                 Economic Sanctions.  The Selling Stockholder will not directly use the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other Person, for the purpose or financing any activities or business of or with any Person that is currently the subject of Sanctions.

(l)                                     Restriction on Sale of Securities.

13

The Selling Stockholder will indemnify and hold harmless each Indemnified Party against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Statutory Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement thereto, in the light of the circumstances under which they were made) not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by the Selling Stockholder expressly for use therein, it being understood and agreed that the only such information furnished by the Selling Stockholder consists of the Selling Stockholder Information, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that (x) the indemnification and reimbursement obligations provided for in this Section 9(b) shall only apply to untrue statements or alleged untrue statements or omissions or alleged omissions made in the Registration Statement, any Statutory Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by the Selling Stockholder expressly for use therein, it being understood and agreed that the only such information furnished by the Selling Stockholder consists of the Selling Stockholder Information, and (y) the Selling Stockholder will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through Representative specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below.

(c)                                  Indemnification of the Company and Selling Stockholder.  Each Underwriter will severally and not jointly indemnify and hold harmless the Company, each of its directors and each of its officers who signs a Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and the Selling Stockholder, each of its directors and officers and each person, if any, who controls the Selling Stockholder within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”) against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, or other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement at any time, any Statutory Prospectus at any time, the Final

16

Prospectus or any Issuer Free Writing Prospectus or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter: the information concerning selling concessions in the fourth paragraph under the caption “Underwriting”, the information concerning stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Regulation M of the Exchange Act in the twelfth and thirteenth paragraphs under the caption “Underwriting” and the information concerning online and internet allocations in the fourteenth paragraph under the caption “Underwriting” (collectively, the “Underwriter Information”).

(d)                                 Actions against Parties; Notification.  Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a), (b) or (c) above.  In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(e)                                  Contribution.  If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Stockholder on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, the Selling Stockholder or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an

17

indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint.  The Company, the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9(e).

10.                               Default of Underwriters.  If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the First Closing Date or any Optional Closing Date and the aggregate number of shares of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, Credit Suisse may make arrangements for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the number of shares of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to Credit Suisse, the Company and the Selling Stockholder for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholder, except as provided in Section 11 (provided, that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

11.                               Survival of Certain Representations and Obligations.  The respective indemnities, agreements, representations, warranties and other statements of the Selling Stockholder, of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Selling Stockholder, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 10 hereof, the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company and the Underwriters pursuant to Section 9 hereof shall remain in effect.  In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 6 shall also remain in effect.

12.                               Notices.  All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed or delivered and confirmed to the Representatives, c/o Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention:  LCD-IBD; if sent to the Company, will be mailed, delivered or telegraphed and confirmed to Bonanza Creek Energy, Inc., 410 17th Street, Suite 1400, Denver, Colorado 80202, Attention: General Counsel; or if sent to the Selling Stockholder, will be mailed or delivered and confirmed to Project Black Bear LP, 2 Bloor Street East, Toronto, Ontario M4W 1A8 Canada, Attention: General Counsel; provided, however, that any notice to an Underwriter pursuant to Section 9 will be mailed, delivered or telegraphed and confirmed to such Underwriter, which address will be supplied to the Company by the Representatives upon request.

18

13.                               Successors.  This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 9, and no other person will have any right or obligation hereunder.

14.                               Representation of Underwriters.  The Representatives will act for the several Underwriters in connection with the transactions contemplated by this Agreement, and any action under this Agreement taken by the Representatives will be binding upon all the Underwriters.

15.                               Counterparts.  This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.  This Agreement may be executed by facsimile signature or signature delivered by other electronic means and all such signatures shall be effective as originals. This Agreement supersedes all prior agreements and understandings (whether written or oral) among the Company, the Selling Stockholder and the Underwriters, or any of them, with respect to the subject matter hereof.

16.                               Absence of Fiduciary Relationship.  Each of the Company and the Selling Stockholder, severally and not jointly, acknowledges and agrees that:

(a)                                 No Other Relationship.  The Representatives have been retained solely to act as an underwriter in connection with the sale of Offered Securities and no fiduciary, advisory or agency relationship between the Company and the Representatives has been created in respect of any of the transactions contemplated by this Agreement or the Final Prospectus, irrespective of whether the Representatives have advised or is advising the Company on other matters.

(b)                                 Arms’ Length Negotiations.  The price of the Offered Securities set forth in this Agreement was established by the Selling Stockholder following discussions and arms-length negotiations with the Representatives, and the Company and the Selling Stockholder are capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement.

(c)                                  Absence of Obligation to Disclose.  The Company and the Selling Stockholder have been advised that the Representatives and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company or the Selling Stockholders and that the Representatives have no obligation to disclose such interests and transactions to the Company or the Selling Stockholder by virtue of any fiduciary, advisory or agency relationship.

(d)                                 Waiver.  Each of the Company and the Selling Stockholder, severally and not jointly, waives, to the fullest extent permitted by law, any claims it may have against the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Representatives shall have no liability (whether direct or indirect) to the Company or the Selling Stockholders in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

17.                               Applicable Law.  THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK.

18.                               Submission to Jurisdiction. The Company and the Selling Stockholder, severally and not jointly, hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.  Each of the Company and the Selling Stockholder, severally and not jointly, irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

ANNEX A

Form of Comfort Letter

The Representative shall have received letters, dated, respectively, the date hereof and the First Closing Date, of Hein & Associates LLP confirming that they are a registered public accounting firm and independent public accountants within the meaning of the Securities Laws to the effect that:

(i)  in their opinion the audited consolidated financial statements and schedules examined by them and included in the Registration Statements and the General Disclosure Package comply as to form in all material respects with the applicable accounting requirements of the Securities Laws;

(ii)  with respect to the period(s) covered by the unaudited quarterly consolidated financial statements included in the Registration Statement and the General Disclosure Package, they have performed the procedures specified by the American Institute of Certified Public Accountants for a review of interim financial information as described in AU 722, Interim Financial Information, on the unaudited quarterly consolidated financial statements (including the noted thereto) of the Company and its consolidated subsidiaries included in the Registration Statement and the General Disclosure Package, and have made inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company and its consolidated subsidiaries as to whether such unaudited quarterly consolidated financial statements comply as to form in all material respects with the applicable accounting requirements of the Securities Act and the related published rules and regulations; they have read the latest unaudited monthly consolidated financial statements (including the notes thereto) and the supplementary summary unaudited financial information of the Company and its consolidated subsidiaries made available by the Company and the minutes of the meetings of the stockholders, Board of Directors and committees of the Board of Directors of the Company; and have made inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company and its consolidated subsidiaries as to whether the unaudited monthly financial statements are stated on a basis substantially consistent with that of the audited consolidated financial statements included in the Registration Statement and General Disclosure Package; and on the basis thereof, nothing came to their attention which caused them to believe that:

(A) the unaudited financial statements included in the Registration Statement or the General Disclosure Package do not comply as to form in all material respects with the applicable accounting requirements of the Securities Laws, or that any material modifications should be made to the unaudited quarterly consolidated financial statements for them to be in conformity with generally accepted accounting principles; and

(B) with respect to the period subsequent to the date of the most recent unaudited quarterly consolidated financial statements included in the General Disclosure Package, at a specified date at the end of the most recent month, there were any increases in the short-term debt or long-term debt of the Company and its consolidated subsidiaries, or any change in stockholders’ equity or the consolidated capital stock of the Company and its consolidated subsidiaries or any decreases in the net current assets or net assets of the Company and its consolidated subsidiaries, as compared with the amounts shown on the latest balance sheet included in the General Disclosure Package; or for the period from the day after the date of the most recent unaudited quarterly consolidated financial statements for such entities included in the General Disclosure Package to such specified date, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated net sales or net operating income, or in the total or per share amounts of consolidated net income of the Company and its consolidated subsidiaries, except for such changes, increases or decreases set forth in such letter which the General Disclosure Package discloses have occurred or may occur;

(iii)  With respect to any period as to which officials of the Company have advised that no consolidated financial statements as of any date or for any period subsequent to the specified date referred to in (ii)(B) above are available, they have made inquiries of certain officials of the Company who have responsibility for the financial and accounting matters of the Company and its consolidated subsidiaries as to whether, at a specified date not more than three business days prior to the date of such letter, there were any increases in the short-term debt or long-term debt of the Company and its consolidated subsidiaries, or any change in stockholders’ equity or the consolidated capital stock of the Company and its consolidated subsidiaries or any decreases in the net assets of the Company and its consolidated subsidiaries, as compared with the amounts shown on the most recent balance sheet for such entities included in the General Disclosure Package; or for the period from the day after the date of the most recent unaudited quarterly financial statements for such entities included in the General Disclosure Package to such specified date, there were any decreases, as compared with the corresponding period in the preceding year, in net sales, or net operating income, or in the total or per share amounts of consolidated net income of the Company and its consolidated subsidiaries and, on the basis of such inquiries and the review of the minutes described in paragraph (ii) above, nothing came to their attention which caused them to believe that there was any such change, increase, or decrease, except for such changes, increases or decreases set forth in such letter which the General Disclosure Package discloses have occurred or may occur; and

(iv)  they have compared specified dollar amounts (or percentages derived from such dollar amounts) and other financial and statistical information contained in the Registration Statement, each Issuer Free Writing Prospectus (other than any Issuer Free Writing Prospectus that is an “electronic road show,” as defined in Rule 433(h)) and the General Disclosure Package (in each case to the extent that such dollar amounts, percentages and other financial and statistical information are derived from the general accounting records of the Company and its subsidiaries or are derived directly from such records by analysis or computation) with the results obtained from inquiries, a reading of such general accounting records and other procedures specified in such letter and have found such dollar amounts, percentages and other financial and statistical information to be in agreement with such results.

All financial statements and schedules included in material incorporated by reference into the Registration Statement or the General Disclosure Package shall be deemed included in the Registration Statement or the General Disclosure Package for purposes of this Schedule.

CREDIT SUISSE SECURITIES (USA) LLC

RAYMOND JAMES & ASSOCIATES, INC.,

As Representatives of the Several Underwriters,

c/o Credit Suisse Securities (USA) LLC,

Eleven Madison Avenue,

New York, N.Y. 10010-3629

Ladies and Gentlemen:

The undersigned understands that Credit Suisse Securities (USA) LLC (“Credit Suisse”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Bonanza Creek Energy, Inc., a Delaware corporation (the “Company”), providing for the public offering (the “Public Offering”) by the several Underwriters, including Credit Suisse (the “Underwriters”), of shares (the “Shares”) of the common stock, par value $0.001 per share (the “Common Stock”), of Project Black Bear LP (the “Selling Stockholder”).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of Credit Suisse on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 90 days after the date of the final prospectus relating to the Public Offering (the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise.  The foregoing sentence shall not apply to (a) any shares of Common Stock to be sold by the undersigned in the Public Offering, (b) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made during the Restricted Period in connection with subsequent sales of Common Stock or other securities acquired in such open market transactions, (c) transfers of shares of Common Stock or any security convertible into Common Stock as a bona fide gift, including as a result of the operation of law or estate intestate succession, (d) distributions of shares of Common Stock or any security convertible into Common Stock to partners, members or stockholders of the undersigned, to any trust, partnership, limited liability company or other entity for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for the purposes of this letter agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than second cousin), or transfers to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned or the undersigned’s affiliates; provided that in the case of any transfer or distribution pursuant to clause (c) or (d), (i) each donee or distributee shall sign and deliver a letter agreement substantially in the form of this letter agreement and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Restricted Period in connection with any such transfer or distribution, (e) any shares of Common Stock indirectly beneficially owned by the undersigned to the extent the undersigned retains only shared voting power, and not any direct or indirect dispositive power, over such shares, (f) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Common Stock, provided that such plan does not provide for the transfer of Common Stock during the Restricted

Period and no public announcement or filing under the Exchange Act regarding the establishment of such plan shall be required of or voluntarily made by or on behalf of the undersigned or the Company, (g) transfers of shares of Common Stock to the Company for purposes of satisfying withholding taxes on shares that vest during the Restricted Period under the Company’s Long Term Incentive Plan, (h) tenders of shares of Common Stock made in response to a bona fide third party take-over bid made to all holders of shares of Common Stock or any other acquisition transaction whereby all or substantially all of the shares of Common Stock are to be acquired by a third party or (i) as otherwise directed by or pursuant to that certain Interim Award of Arbitrators, Case 72 198 Y 00661 11 JMLE, dated November 30, 2012.  In addition, the undersigned agrees that, without the prior written consent of Credit Suisse on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 90 days after the date of the final prospectus relating to the Public Offering, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock.  The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except pursuant to the Public Offering or otherwise in compliance with the foregoing restrictions.

If:

(1)                                 during the last 17 days of the initial Restricted Period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or

(2)                                 prior to the expiration of the initial Restricted Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the initial Restricted Period or provides notification to Credit Suisse of any earnings release, or material news or a material event that may give rise to an extension of the initial 90-day Restricted Period;

then, in either case, the Restricted Period will be extended until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless Credit Suisse, on behalf of the Underwriters, waives, in writing, such extension.

The undersigned shall not engage in any transaction that may be restricted by this letter agreement during the 34-day period beginning on the last day of the initial Restricted Period unless the undersigned requests and receives prior written confirmation from the Company or Credit Suisse that the Restricted Period (as the same may have been extended pursuant to the previous paragraph) has expired.

It is understood that, if the Company notifies the Underwriters that it does not intend to proceed with the Public Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares of Common Stock to be included in the Public Offering, the undersigned will be released from all obligations under this letter agreement and this letter agreement shall be deemed void ab initio.

The undersigned understands that the Company and the Underwriters are relying upon this letter agreement in proceeding toward consummation of the Public Offering.  The undersigned further understands that this letter agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions.  Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation among the Company, the Selling Stockholder and the Underwriters.

ANNEX C-2

Form of Negative Assurance of Mayer Brown

Nothing has come to our attention that causes us to believe that:

(1) the Registration Statement or the prospectus included therein (except for the financial statements and financial schedules and the estimated oil and natural gas reserve evaluations and related calculations and other financial and reserve data included therein, as to which we do not express any belief) at the time the Registration Statement became effective contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(2) the General Disclosure Package (except for the financial statements and financial schedules and the estimated oil and natural gas reserve evaluations and related calculations and other financial and reserve data included therein, as to which we do not express any belief) as of the date of the Underwriting Agreement or as amended or supplemented, if applicable, as of the Closing Date contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or

(3) the Final Prospectus (except for the financial statements and financial schedules and the estimated oil and natural gas reserve evaluations and related calculations and other financial and reserve data included therein, as to which we do not express any belief) as of its date or as amended or supplemented, if applicable, as of the Closing Date contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

ANNEX D

Form of Opinion of Sidley Austin LLP, Counsel to the Selling Stockholder

(i)  Upon (a) the payment to the Selling Stockholder of the purchase price for the Offered Securities to be sold by the Selling Stockholder as provided in the Underwriting Agreement, (b) the delivery of such Offered Securities, as directed by the Underwriters, to Cede & Co. (“Cede”) or such other nominee as may be designated by The Depository Trust Company (“DTC”), and (c) the crediting of such Offered Securities on the books of DTC to “securities accounts” (as defined in Section 8-501(a) of the Uniform Commercial Code as in effect on the date of the opinion letter in the State of New York (the “UCC”)) of the Underwriters, (i) under Section 8-501 of the UCC, the Underwriters will acquire a “security entitlement” (within the meaning of Section 8-501(b) of the UCC) in respect of such Offered Securities, and (ii) no action based on any “adverse claim” (as defined in Section 8-102 of the UCC) to such Offered Securities may be successfully asserted against the Underwriters with respect to such security entitlement.  For purposes of rendering the opinion set forth in this paragraph, such counsel may assume that when such payment, delivery and crediting occur, (A) such Offered Securities will have been registered in the name of Cede or another nominee designated by DTC, in each case on the Company’s share registry in accordance with its certificate of incorporation, by-laws and applicable law, (B) DTC will be registered as a “clearing corporation” within the meaning of Section 8-102 of the UCC, (C) appropriate entries to the accounts of the several Underwriters on the records of DTC will have been made pursuant to the UCC, (D) the jurisdiction of DTC is New York and (E) no Underwriter will have “notice of an adverse claim” to any of the Offered Securities within the meaning of Section 8-105 of the UCC;

(ii)   The sale of the Offered Securities to be sold by the Selling Stockholder under the Underwriting Agreement and the consummation by the Selling Stockholder of the transactions therein contemplated will not violate the certificate of limited partnership or limited partnership agreement of the Selling Stockholder, result in a breach of, or constitute a default under, the Reg Rights Agreement, or contravene any provision of Applicable Laws.  The term “Applicable Laws” means the Delaware Revised Uniform Limited Partnership Act (as amended, the “DRULPA”) and those state laws of the State of New York, and those federal laws of the United States of America, which, in such counsel’s experience and without independent investigation, are normally applicable to transactions of the type contemplated by the Underwriting Agreement; provided, that the term “Applicable Laws” shall not include federal or state securities or blue sky laws (including, without limitation, the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended), antifraud laws or in each case any rules or regulations thereunder;

(iii)  No consent, approval, authorization or other order of any federal regulatory body, federal administrative agency or other federal governmental body of the United States of America or any state regulatory body, state administrative agency or other state governmental body of the State of New York is required to be obtained by the Selling Stockholder under Applicable Laws for the consummation by the Selling Stockholder of the transactions contemplated by the Underwriting Agreement in connection with the Offered Securities to be sold by the Selling Stockholder under the Underwriting Agreement;

(iv)  The Underwriting Agreement has been duly authorized, executed and delivered by the Selling Stockholder.
