Underwriting Agreements
On July 11, 2013, Merrimack Pharmaceuticals, Inc. (the Company) entered into an underwriting agreement (the Equity Underwriting Agreement) with the underwriters listed therein (the Equity Underwriters), for which J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated are acting as representatives, to issue and sell to the Equity Underwriters 5,000,000 shares of the Companys common stock (the Shares) in a public offering pursuant to a Registration Statement on Form S-3 (File No. 333-186369) (the Registration Statement) and a related prospectus filed with the Securities and Exchange Commission (the SEC), at a public offering price of $5.00 per share (the Common Stock Offering). The Company also granted the Equity Underwriters an option, exercisable for 30 days, to purchase up to an additional 750,000 shares of its common stock at the public offering price less underwriting discounts and commissions. The Company estimates that the net proceeds from the Common Stock Offering, after deducting underwriting discounts and commissions and estimated offering expenses payable by the Company, will be approximately $23.3 million (or approximately $26.8 million if the Equity Underwriters exercise in full their option to purchase additional shares).
On July 11, 2013, the Company also entered into an underwriting agreement (the Notes Underwriting Agreement) with the underwriters listed therein (the Note Underwriters), for which J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated are acting as representatives, to issue and sell to the Note Underwriters $125,000,000 in aggregate principal amount of 4.50% Convertible Senior Notes due 2020 (the Notes) in a public offering pursuant to the Registration Statement and a related prospectus filed with the SEC (the Convertible Notes Offering). The Company also granted the Note Underwriters an option, exercisable for 30 days, to purchase up to an additional $18,750,000 in aggregate principal amount of the Notes at the public offering price less underwriting discounts and commissions. The Notes are to be issued pursuant to a base indenture, as supplemented by a supplemental indenture (as so supplemented, the Indenture), in each case, to be entered into between the Company and Wells Fargo Bank, National Association, as trustee. The Company estimates that the net proceeds from the Convertible Notes Offering, after deducting underwriting discounts and commissions and estimated offering expenses payable by the Company, will be approximately $120.6 million (or approximately $138.8 million if the Note Underwriters exercise in full their option to purchase additional Notes).
Each of the Equity Underwriting Agreement and the Notes Underwriting Agreement contains customary representations, warranties and covenants of the Company, conditions to closing, indemnification obligations of the Company and the Equity Underwriters and the Notes Underwriters, respectively, and termination and other customary provisions.
The above descriptions of the Equity Underwriting Agreement and Notes Underwriting Agreement are qualified in their entirety by reference to the Equity Underwriting Agreement and Notes Underwriting Agreement, copies of which are filed as Exhibit 1.1 and Exhibit 1.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.

(Hercules) entered into an amendment, consent and waiver to the Loan and Security Agreement dated as of November 8, 2012 by and between the Company and Hercules (the Loan and Security Agreement) that permits the offering and issuance of the Notes (the Hercules Amendment).

· the Company agreed not to amend or modify the terms of the Notes or the Indenture in a manner adverse to Hercules;

· the Company and Hercules agreed to certain other ministerial amendments to permit the offering and issuance of the notes under the terms of the Loan and Security Agreement and related matters.
