ARTICLE I

NOTES

Section 1.01. Purchase and Delivery of the Senior Notes. Subject to the terms and conditions of this Agreement, at each Closing (as defined herein), the Company hereby agrees to

issue to each Purchaser, and each Purchaser (severally and not jointly) hereby agrees to purchase from the Company, (a) a Senior Note having a principal amount as set forth opposite the name of such Purchaser on Schedule 1.01 hereto in the column labeled “Purchase Price” for such Closing (the “Purchase Price”) and (b) Warrants, the form of which is attached hereto as Exhibit B, to purchase a number of shares (rounded to the nearest whole number) of Common Stock determined by multiplying such Purchase Price by .30 and dividing the result by $0.6189 (collectively, the “Warrants”). Each Purchaser acknowledges that the Senior Notes purchased by such Purchaser at any Closing and therefore the Purchase Price that will be released from escrow to the Company may be adjusted and one or more additional Subsequent Closings may be held with the consent of the Senior Eligible Securities Majority; provided, however, that no such adjustment shall change the percentage of the Senior Notes issued at such Closing (or all Closings taken together) purchased by such Purchaser and in no event shall such Purchaser be required to purchase more Senior Notes than the “Aggregate Purchase Price” specified for such Purchaser on Schedule 1.01 hereto.

Section 1.02. Closings.

(a) The first purchase and issuance of Senior Notes and Warrants shall take place on the date hereof or the first date thereafter on which the conditions set forth in Section 5.01 are satisfied (the “First Closing”). Unless previously cancelled pursuant to the terms of this Agreement: (i) the second purchase and issuance of Senior Notes and Warrants shall take place on March 7, 2011 subject to the consent of the Senior Eligible Securities Majority or on such other date as the Company and the Senior Eligible Securities Majority shall agree (the “Second Closing”); (ii) the third purchase and issuance of Senior Notes and Warrants shall take place on December 7, 2011 subject to the consent of the Senior Eligible Securities Majority or on such other date as the Company and the Senior Eligible Securities Majority shall agree (the “Third Closing”); (iii) the fourth purchase and issuance of Senior Notes and Warrants shall take place on March 7, 2012 subject to the consent of the Senior Eligible Securities Majority or on such other date as the Company and the Senior Eligible Securities Majority shall agree (the “Fourth Closing”); and (iv) to the extent any amounts representing the Aggregate Purchase Price remain in the escrow following the Fourth Closing (exclusive of any other amounts, including any accrued interest), one or more additional Subsequent Closings (as defined below) shall take place on such date(s) as the Company and the Senior Eligible Securities Majority shall agree. The First Closing, Second Closing, Third Closing, Fourth Closing and any additional Subsequent Closings are each sometimes referred to herein as a “Closing” and together as the “Closings.” The Closings other than the First Closing are each sometimes referred to herein as a “Subsequent Closing” and together as the “Subsequent Closings.” Notwithstanding anything herein to the contrary and subject to the following sentence, the Senior Eligible Securities Majority shall have the right at any time prior to any Subsequent Closing to accelerate or defer the purchase and issuance of all or any portion of the Senior Notes and Warrants, including the right to change the aggregate amount subject to purchase at a Closing. Any such acceleration or deferral shall be (i) pro rata among the Purchasers based on the amount of Senior Notes remaining to be purchased by each and (ii) applied against or added to the Senior Notes and Warrants scheduled to be purchased at the next succeeding Subsequent Closings. In no event shall the total amount of Senior Notes and Warrants exceed the maximum amount of Senior Notes and Warrants to be purchased hereunder.

(b) At the First Closing, (i) the Company shall issue and deliver to each Purchaser a Senior Note in an original principal amount equal to such Purchaser’s Purchase Price for the First Closing, (ii) the Company shall issue and deliver to each Purchaser such Purchaser’s Warrant for the First Closing, (iii) each Purchaser shall deliver to JPMorgan Chase Bank, N.A. as escrow agent (the “Escrow Agent”), pursuant to the Escrow Agreement attached as Exhibit E hereto, such Purchaser’s aggregate Purchase Price for all Closings by wire transfer of immediately available funds to the account designated in writing by the Escrow Agent and (iv) the Escrow Agent shall deliver to the Company each Purchaser’s Purchase Price for the First Closing. Notwithstanding the foregoing, if Saints Capital VI, L.P. (“Saints”) does not deliver the aggregate amount of its portion of the Purchase Price to the Escrow Agent at the First Closing, then (i) on or before January 18, 2011 (the “Outside Date”), Saints shall deliver to the Escrow Agent (to the account designated by the Escrow Agent), by wire transfer of immediately available funds, Saints’ Purchase Price in respect of all Closings, and (ii) the Company shall not issue or deliver to Saints its Senior Note and Warrant for the First Closing unless and until Saints’ Purchase Price in respect of the First Closing is delivered to the Company by the Escrow Agent (it being understood that such Senior Note and Warrant to be issued to Saints will be dated as of the date that Saints delivers its aggregate Purchase Price in respect of all Closings in accordance with clause (i) above). In the event that Saints does not deliver its aggregate Purchase Price in respect of all Closings by the Outside Date, (x) Saints will lose all rights to purchase Senior Notes or Warrants hereunder and (y) the Company shall offer each Purchaser its respective Proportionate Percentage of the Senior Notes and Warrants that would have otherwise been issued to Saints under this Agreement (the “Saints Securities”) and any Purchaser, by notice to the Company within two (2) days of the Outside Date, may elect to purchase the full amount of its Proportionate Percentage of Saints Securities. As used in this Section, the term “Proportionate Percentage” shall mean, with respect to each Purchaser, a fraction, the numerator of which is the aggregate principal amount of Senior Notes such Purchaser is purchasing hereunder, the denominator of which is the aggregate principal amount of all Senior Notes being purchased hereunder. Any Purchaser that purchases the full amount of its Proportionate Percentage of the Saints Securities may purchase any amount of Saints Securities that are not purchased by the other Purchasers. The closing of the sale of all Saints Securities shall occur on January 20, 2011 (or on such other date as may determined by the Purchasers purchasing a majority of Saints Securities) and Schedule 1.01 hereof shall be automatically amended to reflect any resulting changes in the Purchase Prices of the Purchasers.

(c) At each Subsequent Closing, if any, (i) the Company shall issue and deliver to each Purchaser a Senior Note in an original principal amount equal to such Purchaser’s Purchase Price for such Closing, (ii) the Company shall issue and deliver to each Purchaser such Purchaser’s Warrant for such Closing, and (iii) the Escrow Agent shall deliver to the Company the aggregate Purchase Price for all Senior Notes purchased at such Closing.

of the outstanding shares of Series C Convertible Preferred Stock and Series B Convertible Preferred Stock, voting together as a single class on an as-converted basis, have not waived the applicability of Article Fourth, Section B.3(d)(iii)(D) of the Charter with respect to the issuance of the Senior Notes and the Warrants, (c) one or more holders of the shares of Series A-1 Convertible Preferred Stock or more than 400,000 shares of Series B Convertible Preferred Stock or Series C Convertible Preferred Stock outstanding as of the date hereof will acquire at least its Pro Rata Share of the Available Additional Shares (as defined in the Charter) of the Senior Notes and the Warrants to be issued pursuant to this Agreement and (d) the Board of Directors of the Company (the “Board”) (including at least three of the five directors elected by the holders of the Convertible Preferred Stock (as defined in the Charter)) have allocated Senior Notes and Warrants to the holders of at least 75,000 shares of Series A-1 Convertible Preferred Stock, holders of at least 400,000 shares of Series C Convertible Preferred Stock and holders at least 400,000 shares of Series B Convertible Preferred Stock (other than CII and Radius, as such terms are defined in the Charter) as set forth on Schedule 1.03.

SENIOR CONVERTIBLE DEMAND

PROMISSORY NOTE PURCHASE AGREEMENT

This AMENDMENT, dated as of February 3, 2011 (this “Amendment”), to the Senior Convertible Demand Promissory Note Purchase Agreement, dated as of January 10, 2011 (the “2011 Note Purchase Agreement”), by and among Rib-X Pharmaceuticals, Inc., a Delaware corporation (the “Company”) and the Purchasers (as defined therein). Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to them in the 2011 Note Purchase Agreement.

W I T N E S S E T H :

WHEREAS, on the terms and subject to the conditions set forth in the 2011 Note Purchase Agreement, the Purchasers have agreed to purchase from the Company up to (i) an aggregate of $20,000,000 of original principal amount of Senior Notes and (ii) Warrants to purchase an aggregate of 9,694,620 shares of Common Stock (collectively, the “Senior Note Financing”);

WHEREAS, in connection with the Senior Note Financing, EuclidSR Partners, L.P. and EuclidSR Biotechnology Partners L.P. (collectively “Euclid”) did not exercise its right to purchase up to (i) an aggregate of $1,032,707 of original principal amount of Senior Notes (the “Euclid Notes”) and (ii) Warrants to purchase an aggregate of 500,585 shares of Common Stock (the “Euclid Warrants”) from the Company;

WHEREAS, Saints, which is already a party to the 2011 Note Purchase Agreement having agreed to purchase from the Company up to (i) an aggregate of $1,481,243 of original principal amount of Senior Notes and (ii) Warrants to purchase an aggregate of 718,004 shares of Common Stock, wishes to purchase from the Company, and the Company wishes to issue to Saints, the Euclid Notes and the Euclid Warrants (the “Saints Additional Purchases”);

WHEREAS, Section 6.09 of the 2011 Note Purchase Agreement provides that the 2011 Note Purchase Agreement may be amended by the Senior Eligible Securities Majority; and

WHEREAS, in connection with the Saints Additional Purchases, the Company and the Senior Eligible Securities Majority desire to amend certain provisions of the 2011 Note Purchase Agreement as more fully set forth herein.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and in consideration of the agreements herein, the parties hereto agree as follows:

1. Amendments.

(a) Schedule 1.01 of the 2011 Note Purchase Agreement shall be amended and restated to reflect the Additional Saints Investment and to read in its entirety to read as set forth on Schedule 1.01 attached hereto.

(b) Section 1.02(b) of the 2011 Note Purchase Agreement shall be amended to include the following at the end thereof:

“Notwithstanding the foregoing, in addition to the $1,481,243 of original principal amount of Senior Notes and Warrants to purchase an aggregate of 718,004 shares of Common Stock from the Company that Saints has heretofore agreed to purchase pursuant to the terms and conditions of this Agreement, Saints agrees to purchase an additional aggregate of $1,032,707 of original principal amount of Senior Notes (the “Additional Notes”) and Warrants to purchase an aggregate of 500,585 shares of Common Stock (the “Additional Warrants”) pursuant to the terms and conditions of this Agreement. In respect of the Additional Notes and Additional Warrants, on the date hereof Saints shall deliver to the Escrow Agent (to the account designated by the Escrow Agent), by wire transfer of immediately available funds, Saints’ Purchase Price in respect of Additional Notes and Additional Warrants for all Closings, and (ii) the Company shall not issue or deliver to Saints its Additional Note and Additional Warrant for the First Closing unless and until Saints’ Purchase Price in respect of Additional Notes and Additional Warrants for the First Closing is delivered to the Company by the Escrow Agent (it being understood that such Additional Note and Additional Warrant to be issued to Saints will be dated as of the date that Saints delivers its aggregate Purchase Price in respect of Additional Notes and Additional Warrants for all Closings in accordance with clause (i) above).”

(c) Section 1.03 of the 2011 Note Purchase Agreement shall be amended to replace the last sentence thereof with the following:

“In connection with the foregoing, in the event that any stockholder set forth on Schedule 1.03 hereto, together with its affiliates (as defined in the Charter and including any funds under common management), fails to purchase all of its Pro Rata Share of the Available Additional Shares of the Senior Notes and the Warrants (each as set forth opposite the name of such Purchaser on Schedule 1.03 hereto), such stockholder shall be subject to Article Fourth, Section B.3(d)(iii)(D) of the Charter; provided, however, that solely for this purpose, the purchase of Notes and Warrants by Saints shall be deemed to satisfy the purchase of the Pro Rata Share of the Available Additional Shares allocated to EuclidSR Biotechnology Partners, L.P. and EuclidSR Partners, L.P.”

(d) Section 6.09 of the 2011 Note Purchase Agreement shall be amended and restated to read in its entirety to read as set forth below:

“Section 6.09. Amendments and Waivers. This Agreement may be amended or modified, and provisions hereof may be waived, only with the written consent of the Company and the Senior Eligible Securities Majority; provided, however, that (a) the “Aggregate Purchase Price” specified for a Purchaser on Schedule 1.01 hereto may not be increased, and (b) the percentage of Senior Notes to be purchased at any Closing by a Purchaser may not be amended except as a result of an increase in the “Aggregate Purchase Price” specified for another Purchaser on Schedule 1.01 hereto, in each case, without the written consent of such Purchaser;

-2-

provided, further, that any amendment modification or waiver of a provision of this Agreement that by its terms treats a particular Purchaser in a materially different and adverse manner relative to the other Purchasers shall not be binding as to such Purchaser unless such Purchaser consents in writing to the amendment, modification or waiver.”

2. No Other Amendment. Except as expressly amended hereby, the 2011 Note Purchase Agreement shall remain in full force and effect in accordance with its terms, without any waiver, amendment or modification of any provision thereof. All references in the 2011 Note Purchase Agreement to “this Agreement” shall be deemed to refer to the 2011 Note Purchase Agreement as amended by this Amendment.

3. Governing Law; Jurisdiction. This Amendment shall be construed, performed and enforced in accordance with, and governed by, the laws of the State of Delaware, without giving effect to the principles of conflicts of laws thereof. The parties hereto irrevocably elect as the sole judicial forum for the adjudication of any matters arising under or in connection with this Amendment, and consent to the jurisdiction of, the courts of the State of Delaware or the corresponding United States federal court in the State of Delaware.

4. Section and Paragraph Headings. The section and paragraph headings in this Amendment are for reference purposes only and shall not affect the meaning or interpretation of this Amendment.

5. Counterparts. This Amendment may be executed in counterparts, each of which shall be deemed an original, but all of which shall constitute the same instrument.
