Ladies and Gentlemen:

        Array BioPharma Inc., a Delaware corporation (the "Company"), proposes to issue and sell to the underwriters named in Schedule A annexed hereto (the "Underwriters") an aggregate of 8,000,000 shares (the "Firm Shares") of common stock, $0.001 par value per share (the "Common Stock"), of the Company. In addition, solely for the purpose of covering over-allotments, the Company proposes to grant to UBS Securities LLC ("UBS") the option to purchase from the Company up to an additional 1,200,000 shares of Common Stock (the "Additional Shares"). The Firm Shares and the Additional Shares are hereinafter collectively sometimes referred to as the "Shares." The Shares are described in the Prospectus which is referred to below.

        The Company has prepared and filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the "Act"), with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-3 (File No. 333-114699) under the Act (the "registration statement"). Amendments to such registration statement, if necessary or appropriate, have been similarly prepared and filed with the Commission. Such registration statement, as so amended, has been declared by the Commission to be effective under the Act. The Company has filed with the Commission a Prepricing Prospectus (as defined and referred to below) pursuant to Rule 424(b) under the Act, describing the Shares and the offering thereof, in such form as has been provided to or discussed with, and approved by, the Underwriters. The Company will next file with the Commission pursuant to Rule 424(b) under the Act a final prospectus supplement to the basic prospectus, describing the Shares and the offering thereof, in such form as has been provided to or discussed with, and approved, by the Underwriters.

        The term "Registration Statement" as used in this Agreement means the registration statement, as amended at the time it became effective and as supplemented or amended prior to the execution of this Agreement, including (i) all financial schedules and exhibits thereto and (ii) all documents incorporated by reference or deemed to be incorporated by reference therein. If an abbreviated registration statement is prepared and filed with the Commission in accordance with Rule 462(b) under the Act (an "Abbreviated Registration Statement"), the term "Registration Statement" includes the Abbreviated Registration Statement. The term "Basic Prospectus" as used in this Agreement means the basic prospectus dated as of June 18, 2004 and filed with the Commission pursuant to Rule 424(b) for use in connection with the offer and/or sale of Shares pursuant to this Agreement. The term "Prepricing Prospectus" as used in this Agreement means any form of preliminary prospectus used in connection with the marketing of the Shares, including the preliminary prospectus supplement dated as of November 29, 2004 and filed with the Commission on November 30, 2004 pursuant to Rule 424 under the Act and any basic prospectus (whether or not in preliminary form) used with any such preliminary prospectus supplement in connection with the marketing of the Shares, in each case as any of the foregoing may be amended or supplemented by the Company. The term "Prospectus Supplement" as used in this Agreement means any final prospectus supplement specifically relating to the Shares, in the form filed with, or transmitted for filing to, the Commission pursuant to Rule 424 under the Act. The term "Prospectus" as used in this Agreement means the Basic Prospectus together with and as supplemented by the Prospectus Supplement except that if such Basic Prospectus is amended or



supplemented on or prior to the date on which the Prospectus Supplement was first filed pursuant to Rule 424, the term "Prospectus" shall refer to the Basic Prospectus as so amended or supplemented and as supplemented by the Prospectus Supplement. Any reference herein to the registration statement, the Registration Statement, the Basic Prospectus, any Prepricing Prospectus, any Prospectus Supplement or the Prospectus shall be deemed to refer to and include (i) the documents incorporated by reference therein pursuant to Form S-3 (the "Incorporated Documents") and (ii) the copy of the Registration Statement, the Basic Prospectus, the Prepricing Prospectus, the Prospectus Supplement, the Prospectus or the Incorporated Documents filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR"). Any reference herein to the terms "amend," "amendment" or "supplement" with respect to the Registration Statement, any Prepricing Prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the "Exchange Act") after the effective date of the Registration Statement, or the date of the Prospectus, as the case may be, deemed to be incorporated therein by reference. As used herein, "business day" shall mean a day on which the New York Stock Exchange is open for trading.

        The Company and the Underwriters agree as follows:

            1.     Sale and Purchase. Upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Company agrees to issue and sell to the respective Underwriters and each of the Underwriters, severally and not jointly, agrees to purchase from the Company the number of Firm Shares set forth opposite the name of such Underwriter in Schedule A attached hereto, subject to adjustment in accordance with Section 8 hereof, in each case at a purchase price of $7.285 per Share. The Company is advised by you that the Underwriters intend (i) to make a public offering of their respective portions of the Firm Shares as soon after the effective date of the Registration Statement as in your judgment is advisable and (ii) initially to offer the Firm Shares upon the terms set forth in the Prospectus. You may from time to time increase or decrease the public offering price after the initial public offering to such extent as you may determine.

            In addition, the Company hereby grants to UBS the option to purchase, and upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, UBS shall have the right to purchase from the Company all or a portion of the Additional Shares as may be necessary to cover over-allotments made in connection with the offering of the Firm Shares, at the same purchase price per share to be paid by the Underwriters to the Company for the Firm Shares. This option may be exercised by UBS at any time and from time to time on or before the thirtieth day following the date of the Prospectus, by written notice to the Company. Such notice shall set forth the aggregate number of Additional Shares as to which the option is being exercised and the date and time when the Additional Shares are to be delivered (such date and time being herein referred to as the "additional time of purchase"); provided, however, that the additional time of purchase shall not be earlier than the time of purchase (as defined below) nor earlier than the second business day after the date on which the option shall have been exercised nor later than the tenth business day after the date on which the option shall have been exercised.

            2.     Payment and Delivery. Payment of the purchase price for the Firm Shares shall be made to the Company by Federal Funds wire transfer against delivery of the certificates for the Firm Shares to you through the facilities of The Depository Trust Company ("DTC") for the respective accounts of the Underwriters. Such payment and delivery shall be made at 10:00 A.M., New York City time, on December 14, 2004 (unless another time shall be agreed to by you and the Company or unless postponed in accordance with the provisions of Section 8 hereof). The time at which such payment and delivery are to be made is hereinafter sometimes called "the time of purchase."
