EXCHANGE AGREEMENT

This letter agreement (“Agreement”) sets forth the terms and conditions upon which Bill Barrett Corporation, a Delaware corporation (“Company”), will issue the number of shares (the “Shares”) of Company’s Common Stock, par value $0.001 per share (“Common Stock”), indicated on the signature page hereof to each holder indicated on the signature page hereof (each, a “Holder”), in exchange for the aggregate principal amount of the Company’s debt securities (the “Exchanged Notes”) identified on the signature page hereof.

Section 1. Exchange. On the terms and subject to the conditions of this Agreement and in reliance upon the representations, warranties and agreements contained herein, each Holder agrees to exchange the Exchange Notes with Company in consideration of and in exchange for the transfer by Company to such Holder of the Shares. As promptly as reasonably practicable, but in no event later than five business days after the execution of this Agreement, each Holder shall deliver the Exchanged Notes on behalf of Company to Deutsche Bank Trust Company Americas (“Trustee”) by means of the book-entry transfer procedures of The Depositary Trust Company, as depositary for the Notes, or by other due and proper agreements or instruments of transfer reasonably acceptable to Company and its legal counsel. No adjustment shall be made or Shares issued for interest accrued on any Exchanged Note. Subject to and upon such delivery of the Exchanged Notes, as promptly as reasonably practicable, but in no event later than five business days after the execution of this Agreement, the Company shall cause (i) the transfer agent for the Common Stock to issue and deliver the Shares through the facilities of The Depository Trust Company to the account of each Holder set forth on the signature page hereof and (ii) cash representing all accrued but unpaid interest in respect of the Exchanged Notes up to but not including the closing date by wire transfer of immediately available funds in accordance with wire instructions delivered in writing to Company by each Holder prior to the closing date.

Section 2. Conditions to Closing. The obligations of Company and each Holder hereunder to consummate the transactions contemplated by this Agreement are subject to the satisfaction of each of the following conditions:

(a)    Each of the representations and warranties of Company and each Holder contained in Section 4 and Sections 3 and 5, respectively, of this Agreement shall be true and correct in all material respects on and as of the closing date of the transactions described herein with the same effect as though such representations and warranties had been made on and as of the closing date of the transactions described herein.

(b)    Each of Company and each Holder shall in all material respects have performed, satisfied and complied with all of its respective covenants, agreements and conditions contained in this Agreement that are required to be performed, satisfied or complied with by it on or before the closing date of the transactions described herein.

Section 3. Representations And Warranties Of Holder. Each Holder, severally and not jointly, represents and warrants to the Company, as of the date hereof and as of the date of delivery of the Exchanged Notes that:

(a)    Such Holder is duly organized, validly existing and in good standing in its jurisdiction of organization and the execution, delivery and performance by such Holder of this Agreement, and the consummation of the transactions contemplated hereby, are within the powers of such Holder and have been or will have been duly authorized by all necessary action on the part of such Holder, and this

Agreement constitutes a valid and binding agreement of such Holder, enforceable in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of general application affecting enforcement or creditors’ rights generally or (ii) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies.

(b)    The execution, delivery and performance by such Holder of this Agreement and the consummation of the transactions contemplated hereby require no order, license, consent, authorization or approval of, or exemption by, or action by or in respect of, or notice to, or filing or registration with, any governmental body, agency or official on the part of Holder.

(c)    The execution, delivery and performance by such Holder and Company of this Agreement, and the consummation of the transactions contemplated by this Agreement, do not and will not (i) violate the certificate of incorporation (or similar constituent document) or bylaws of such Holder, (ii) violate any material agreement to which such Holder is a party or by which such Holder or any of its property or assets is bound, or (iii) violate any law, rule, regulation, judgment, injunction, order or decree applicable to such Holder.

(d)    Such Holder has good and valid title to the Exchanged Notes and owns and holds the entire legal and beneficial right, title, and interest in and to the Exchanged Notes (including, without limitation, accrued and unpaid interest thereon), free and clear of any liens, claims or encumbrances (other than those arising as a result of this Agreement) and the Exchanged Notes are not subject to any contract, agreement, arrangement, commitment or understanding restricting or otherwise relating to the disposition of the Exchanged Notes; good and valid title to the Exchanged Notes (including, without limitation, accrued and unpaid interest thereon) will pass to the Company upon consummation of the transaction contemplated hereby and all claims of such Holder relating to the Exchanged Notes, including any accrued and unpaid interest thereon, shall be released.

(e)    Such Holder has such knowledge, sophistication and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Shares. Such Holder acknowledges that it understands the risks inherent in an investment in the Shares and that it has the financial ability to bear the economic risk of, and to afford the entire loss of, its investment in the Shares.

(f)    Such Holder has made its own independent inquiry as to the legal, tax and accounting aspects of the transactions contemplated by this Agreement, and such Holder has not relied on Company, Company's legal counsel or Company's accounting or financial advisors for legal, tax or accounting advice in connection with the transactions contemplated by this Agreement. Such Holder has had such opportunity as it has deemed adequate to obtain from Company such public information as is necessary to permit such Holder to evaluate the merits and risks of the transactions contemplated hereby.

(g)    Such Holder acknowledges that (i) it has reviewed Company's filings with the Securities and Exchange Commission (the “SEC”) and (ii) it is relying only upon the information contained in the Company's filings with the SEC and the representations and warranties of Company in this Agreement and not upon any other information.

(h)    Such Holder acknowledges that Company is in possession of non-public information (the "Non-Public Information"). The Non-Public Information may (or may not) be considered material by such Holder with respect to the exchange of its Exchanged Notes for the Shares. Such Holder has determined that it is in such Holder's best interests to effectuate and close the exchange of Exchanged Notes for the Shares without Company's disclosure to such Holder, and without such Holder's knowledge of, the Non-Public Information. Such Holder has actual knowledge that it may presently have and may

have at or after the time of the closing date of the transactions described herein, claims against Company and Company's directors, officers, employees, agents, attorneys, representatives, affiliates, predecessors, successors and assigns, arising from Company's nondisclosure of the Non-Public Information in connection with the transactions contemplated by this Agreement. As partial consideration for the transactions contemplated by this Agreement, such Holder hereby, on its behalf and on behalf of any and all of its directors, officers, employees, agents, attorneys, representatives, limited partners or other investors, affiliates, predecessors, successors and assigns, unconditionally, irrevocably and absolutely releases and discharges Company and its directors, officers, employees, agents, attorneys, representatives, affiliates, predecessors, successors and assigns from any and all causes of action, claims, demands, damages or liabilities whatsoever, both in law and in equity, in contract, tort or otherwise, which they may now have or may have at or after the closing date of the transactions described herein arising from Company's nondisclosure of the Non-Public Information in connection with the transactions contemplated by this Agreement, in each case to the maximum extent permitted by law.

(i)    Such Holder covenants that neither it nor any person acting on behalf of or pursuant to any understanding with it will engage in any transactions in the securities of Company (including "short sales," as defined in Rule 200 of Regulation SHO under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) prior to the time that the transactions contemplated by this Agreement are publicly disclosed by Company, and represents that no such person has engaged in such a short sale of, or stock pledge, forward sale or other transaction or arrangement with an effect similar to such a short sale with respect to, Company Common Stock from the date the parties commenced the negotiations leading to the execution of this Agreement and the date hereof. Such Holder has maintained, and covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by Company such Holder will maintain, the confidentiality of any disclosures made to it in connection with this transaction (including the existence and terms of this transaction).

(j)    There is no investment banker, broker, finder or other intermediary which has been retained by, will be retained by or is authorized to act on behalf of such Holder who might be entitled to any fee or commission from Company or such Holder upon consummation of the transactions contemplated by this Agreement.

Section 4. Representations And Warranties Of Company. Company represents and warrants to each Holder, as of the date hereof and as of the date of delivery of the Shares, that:

(a)    The Company is duly organized, validly existing and in good standing in the State of Delaware and the execution, delivery and performance by Company of this Agreement, and the consummation of the transactions contemplated hereby, are within the powers of Company and have been or will have been duly authorized by all necessary action on the part of Company, and this Agreement constitutes a valid and binding agreement of Company, enforceable in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of general application affecting enforcement or creditors’ rights generally or (ii) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies.

(b)    The execution, delivery and performance by Company of this Agreement and the consummation of the transactions contemplated hereby require no order, license, consent, authorization or approval of, or exemption by, or action by or in respect of, or notice to, or filing or registration with, any governmental body, agency or official on the part of Company except such consents, approvals, authorizations, filings or registrations (x) as are specifically contemplated by this Agreement or (y) required by applicable law or other regulatory authority.

(c)    The execution, delivery and performance by each Holder and Company of this Agreement, and the consummation of the transactions contemplated by this Agreement, do not and will not (i) violate the amended and restated certificate of incorporation or amended and restated bylaws of Company, (ii) violate any material agreement to which Company is a party or by which Company or any of its property or assets is bound, or (iii) violate any material law, rule, regulation, judgment, injunction, order or decree applicable to Company.

(d)    The Shares, when issued in exchange for the Exchanged Notes in accordance with this Agreement, will be duly and validly authorized and issued, fully-paid and non-assessable, free and clear of all encumbrances, liens, equities or claims. On or before the date of issuance of the Shares, the Shares shall have been authorized for listing on the New York Stock Exchange. The Shares will be freely tradeable and will be fungible in all respects with the Company’s existing shares of Common Stock and will not contain any restrictive legends.

(e)    There is no investment banker, broker, finder or other intermediary which has been retained by, will be retained by or is authorized to act on behalf of Company who would be entitled to any fee or commission from Company or each Holder for soliciting the exchange upon consummation of the transactions contemplated by this Agreement.

Section 5. Exempt Transaction. (a) Each Holder understands that the exchange of the Exchanged Notes for the Shares hereby is intended to be exempt from registration under Section 3(a)(9) of the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”), which exemption depends upon, among other things, the accuracy of the such Holder’s representations expressed herein, and such Holder is not aware of any reason why such exemption is not available.

(b)    Each Holder represents and warrants to Company that it did not purchase the Exchanged Notes with a view to, or for sale in connection with, any distribution of the Shares issuable upon exchange of the Exchanged Notes.

(c)    Each Holder represents and warrants to Company that (i) to the knowledge of such Holder, no commission or other remuneration has been or will be paid or given, directly or indirectly, for soliciting the transactions contemplated hereby and (ii) Company did not, and to the knowledge of such Holder, no person acting on behalf of Company did, solicit such Holder with respect to this disposition of the Exchanged Notes.

(d)    Each Holder represents and warrants to Company that the Exchanged Notes do not constitute “restricted securities” as defined in Rule 144(a)(3) under the Securities Act.

(e)     Each Holder understands that the Shares have not been registered under the Securities Act, and are being issued hereunder in reliance upon a specific exemption from the registration provisions of the Securities Act afforded by Section 3(a)(9) of the Securities Act. Under current interpretations of the SEC, securities that are obtained in a Section 3(a)(9) exchange assume the same character (i.e., restricted or unrestricted) as the securities that have been surrendered. To the extent that the Exchanged Notes are unrestricted securities, the Shares will be unrestricted securities.

(f)    Each Holder represents and warrants to Company that such Holder is not, as of the date hereof, and was not at any time during the three-month period preceding the date hereof, a director or executive officer of the Company or a subsidiary of the Company, a beneficial owner of 5% or more of

the Common Stock, a holder of 5% or more of the voting power outstanding of the Company, or an affiliate of such director, executive officer, beneficial owner or holder.
