 Exhibit 10.47 
 INDEMNIFICATION AGREEMENT 
 THIS INDEMNIFICATION AGREEMENT (this
“Agreement”) is made and entered into this      day of                     ,
20    , by and between Rib-X Pharmaceuticals, Inc., a Delaware corporation (the “Corporation”), and
                     (“Agent”). 
 RECITALS 
 WHEREAS, Agent performs a valuable service to the
Corporation in Agent’s capacity as [a director and/or an officer] of the Corporation; 
 WHEREAS, the Corporation
has adopted provisions providing for indemnification of directors and officers included in its Restated Certificate of Incorporation (the “Charter”) and its bylaws (the “Bylaws”) providing for the
indemnification of the directors, officers, employees and other agents of the Corporation, including persons serving at the request of the Corporation in such capacities with other corporations or enterprises, as authorized by the Delaware General
Corporation Law, as amended (the “DGCL”); 
 WHEREAS, the Charter, the Bylaws and the DGCL, by
their non-exclusive nature, permit contracts between the Corporation and its directors, officers, employees and other agents with respect to indemnification of such persons; 
 WHEREAS, in recognition of Agent’s need for (a) substantial protection against personal liability based on Agent’s reliance on the Charter and the Bylaws, and (b) specific
contractual assurance that the protection provided in the Charter and the Bylaws will be available to Agent (regardless of, among other things, any amendment to or revocation of the Charter and/or the Bylaws, any change in the composition of the
Corporation’s board of directors or a change in control of the Corporation); and 
 WHEREAS, in order to induce
Agent to [continue to] serve as [a director/an officer] of the Corporation, the Corporation has determined and agreed to enter into this Agreement with Agent. 
 NOW, THEREFORE, in consideration of Agent’s service as [a director and/or an officer] of the Corporation following the date hereof, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the Corporation and Agent hereby agree as follows: 
 1. Services to the
Corporation. Agent will serve, at the will of the Corporation or under separate contract, if any such contract exists, as [a director/an officer] of the Corporation or as a director, officer or other fiduciary of an affiliate of the Corporation
(including any employee benefit plan of the Corporation) faithfully and to the best of Agent’s ability so long as Agent [is duly elected and qualified in accordance with the provisions of the Bylaws or other applicable charter documents/is a
duly appointed officer] of the Corporation or such affiliate; provided, however, that Agent may at any time and for any reason resign from such position (subject to any contractual obligation that Agent may have assumed apart from this
Agreement) and that the Corporation or any affiliate shall have no obligation under this Agreement to continue Agent in any such position. 
 2. Indemnity of Agent. The Corporation agrees to hold harmless and indemnify Agent to the fullest extent authorized or permitted by the provisions of the Charter, the Bylaws and the








 
DGCL, as the same may be amended from time to time (but, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than the Charter, the Bylaws or
the DGCL permitted prior to adoption of such amendment). 
 3. Additional Indemnity. In addition to and not in limitation
of the indemnification otherwise provided for herein, and subject only to the exclusions set forth in Section 4 hereof, the Corporation further agrees to hold harmless and indemnify Agent: 

(a) against any and all expenses (including attorneys’ fees), witness fees, damages, judgments, fines and amounts paid in
settlement and any other amounts that Agent becomes legally obligated to pay (including any federal, state or local taxes imposed on Agent as a result of receipt of reimbursements or advances of expenses under this Agreement) because of any claim or
claims made against or by him in connection with any threatened, pending or completed action, suit or proceeding, including any appeal and the premium, security for, and other costs relating to any costs bond, supersedes bond, or other appeal bond
or its equivalent, whether civil, criminal, arbitrational, administrative or investigative, whether formal or informal (including an action by or in the right of the Corporation), to which Agent is, was or at any time becomes a party or a witness,
or is threatened to be made a party or a witness, by reason of the fact that Agent is, was or at any time becomes a director, officer, employee or other agent of the Corporation, or is or was serving or at any time serves at the request of the
Corporation as a director, officer, employee or other agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise; and 
 (b) otherwise to the fullest extent as may be provided to Agent by the Corporation under the non-exclusivity provisions of the DGCL, the Charter and the Bylaws. 

4. Limitations on Additional Indemnity. No indemnity pursuant to Section 3 hereof shall be paid by the Corporation:

 (a) on account of any claim or proceeding against Agent for an accounting of profits made from the purchase or sale by
Agent of securities of the Corporation pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934, as heretofore or hereafter amended (the “Exchange Act”), or similar provisions of any federal,
state or local law, provided, however, if and when Agent ultimately establishes in any such proceeding that no recovery of profits from Agent is permitted under Section 16(b) of the Exchange Act or such similar provision of any similar
federal, state or local law, then, notwithstanding anything to the contrary provided in this Section 4(a), indemnification pursuant to this Agreement shall then be permitted; 

(b) on account of Agent’s conduct that is established by a final judgment as knowingly fraudulent or deliberately dishonest
or that constituted willful misconduct; 
 (c) on account of Agent’s conduct that is established by a final judgment
as constituting a breach of Agent’s duty of loyalty to the Corporation or resulting in any personal profit or advantage to which Agent was not legally entitled; 
 (d) for which payment is actually made to Agent under a valid and collectible insurance policy or under a valid and enforceable indemnity clause, bylaw or agreement, except in respect of any excess
beyond payment under such insurance, clause, bylaw or agreement; 

  
 2 








 (e) if indemnification is not lawful (and, in this respect, both the Corporation and
Agent have been advised that the Securities and Exchange Commission believes that indemnification for liabilities arising under the federal securities laws is against public policy and is, therefore, unenforceable and that claims for indemnification
should be submitted to appropriate courts for adjudication); or 
 (f) in connection with any proceeding (or part
thereof) initiated by Agent, or any proceeding by Agent against the Corporation or its directors, officers, employees or other agents, unless (i) such indemnification is expressly required to be made by law, (ii) the proceeding was
authorized by the board of directors of the Corporation, (iii) such indemnification is provided by the Corporation, in its sole discretion, pursuant to the powers vested in the Corporation under the DGCL, or (iv) the proceeding is
initiated pursuant to Section 11 hereof. 
 5. Continuation of Indemnity. All agreements and obligations of the
Corporation contained herein shall continue during the period Agent is a director, officer, employee or other agent of the Corporation (or is or was serving at the request of the Corporation as a director, officer, employee or other agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other enterprise) and shall continue thereafter so long as Agent shall be subject to any possible claim or threatened, pending or completed action, suit or proceeding, whether
civil, criminal, arbitrational, administrative or investigative, by reason of the fact that Agent was serving in the capacity referred to herein. 
 6. Partial Indemnification. Agent shall be entitled under this Agreement to indemnification by the Corporation for a portion of the expenses (including attorneys’ fees), witness fees, damages,
judgments, fines and amounts paid in settlement and any other amounts that Agent becomes legally obligated to pay in connection with any action, suit or proceeding referred to in Section 3 hereof even if not entitled hereunder to
indemnification for the total amount thereof, and the Corporation shall indemnify Agent for the portion thereof to which Agent is entitled. 
 7. Notification and Defense of Claim. As soon as practicable, and in any event, not later than thirty (30) days after Agent becomes aware, by written or other overt communication, of any
pending or threatened litigation, claim or assessment, Agent will, if a claim in respect thereof is to be made against the Corporation under this Agreement, notify the Corporation of such pending or threatened litigation, claim or assessment; but
the omission so to notify the Corporation will not relieve it from any liability which it may have to Agent otherwise than under this Agreement. With respect to any such pending or threatened litigation, claim or assessment as to which Agent
notifies the Corporation of the commencement thereof: 
 (a) the Corporation will be entitled to participate therein at
its own expense; 
 (b) except as otherwise provided below, the Corporation may, at its option and jointly with any other
indemnifying party similarly notified and electing to assume such defense, assume the defense thereof, with counsel reasonably satisfactory to Agent. After notice from the Corporation to Agent of its election to assume the defense thereof, the
Corporation will not be liable to Agent under this Agreement for any legal or other expenses subsequently incurred by Agent in connection with the defense thereof except for reasonable costs of investigation or otherwise as provided below. Agent
shall have the right to employ separate counsel in such action, suit or proceeding but the fees and expenses of such counsel incurred after notice from the Corporation of its assumption of the defense thereof shall be at the expense of Agent unless
(i) the employment of 

  
 3 








 
counsel by Agent has been authorized by the Corporation, (ii) Agent shall have reasonably concluded, and so notified the Corporation, that there is an actual conflict of interest between the
Corporation and Agent in the conduct of the defense of such action, or (iii) the Corporation shall not in fact have employed counsel to assume the defense of Agent in connection with such action, in any of such cases the fees and expenses of
Agent’s separate counsel shall be at the expense of the Corporation. The Corporation shall not be entitled to assume the defense of any action, suit or proceeding brought by or on behalf of the Corporation or as to which Agent shall have made
the conclusion provided for in clause (ii) above; and 
 (c) the Corporation shall not be liable to indemnify Agent
under this Agreement for any amounts paid in settlement of any action or claim effected without its written consent, which shall not be unreasonably withheld or delayed. The Corporation shall be permitted to settle any action or claim except that it
shall not settle any action or claim in any manner which would impose any penalty or limitation on Agent without Agent’s written consent, which may be given or withheld in Agent’s sole discretion. 

8. Expenses. The Corporation shall advance, prior to the final disposition of any proceeding, promptly following request therefor,
all expenses incurred by Agent in connection with such proceeding upon the Corporation’s receipt of an undertaking by or on behalf of Agent to repay said amounts if it shall be determined ultimately that Agent is not entitled to be indemnified
under the provisions of this Agreement, the Charter, the Bylaws, the DGCL or otherwise. Such undertaking shall be accepted by the Corporation without regard to the financial ability of Agent to make such repayment. Without limiting the foregoing, if
any action, suit or proceeding is disposed of on the merits or otherwise (including a disposition without prejudice), without (i) the final disposition being adverse to Agent, (ii) a final adjudication that Agent was liable to the
Corporation, (iii) a plea of guilty (iv) a final adjudication that Agent did not act in good faith, and in a manner Agent reasonably believed to be in or not opposed to the best interests of the Corporation, or (v) with respect to any
criminal proceeding, a final adjudication that Agent had reasonable cause to believe Agent’s conduct was unlawful, Agent shall be considered for the purposes hereof to have been wholly successful with respect thereto. 

9. Information Sharing. To the extent that the Corporation receives a request or requests from a governmental third party or other
licensing or regulating organization (the “Requesting Agency”), whether formal or informal, to produce documentation or other information concerning an investigation, whether formal or informal, being conducted by the
Requesting Agency, and such investigation is reasonably likely to include review of any actions or failures to act by Agent, the Corporation shall promptly give notice to Agent of said request or requests and any subsequent request. In addition, the
Corporation shall provide Agent with a copy of any and all information or documentation that the Corporation shall provide to the Requesting Agency. 
 10. No Imputation. The knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Corporation or the Corporation itself shall not be imputed to Agent for
purposes of determining any rights under this Agreement. 
 11. Enforcement. Any right to indemnification or advances
granted by this Agreement to Agent shall be enforceable by or on behalf of Agent in any court of competent jurisdiction if (i) the claim for indemnification or advances is denied, in whole or in part, or (ii) no disposition of such claim
is made within ninety (90) days of request therefor. Agent, in such enforcement action, if successful in whole or in part, shall be entitled to be paid also the expense of prosecuting Agent’s


  
 4 








 
claim. It shall be a defense to any action for which a claim for indemnification is made under Section 3 hereof (other than an action brought to enforce a claim for advance or reimbursement
of expenses under this Agreement, provided that the required undertaking has been tendered to the Corporation) that Agent is not entitled to indemnification because of the limitations set forth in Section 4 hereof. Neither the failure of
the Corporation (including its board of directors or its stockholders) to have made a determination prior to the commencement of such enforcement action that indemnification of Agent is proper in the circumstances, nor an actual determination by the
Corporation (including its board of directors or its stockholders) that such indemnification is improper shall be a defense to the action or create a presumption that Agent is not entitled to indemnification under this Agreement or otherwise.

 12. Subrogation. In the event of payment under this Agreement, the Corporation shall be subrogated to the extent of
such payment to all of the rights of recovery of Agent, who shall execute all documents required and shall do all acts that may be necessary to secure such rights and to enable the Corporation effectively to bring suit to enforce such rights.

 13. Non-Exclusivity of Rights. The rights conferred on Agent by this Agreement shall not be exclusive of any other
right which Agent may have or hereafter acquire under any statute, provision of the Charter or Bylaws, agreement, vote of stockholders or directors, or otherwise, both as to action in Agent’s official capacity and as to action in another
capacity while holding office. 
 14. Survival of Rights. 

(a) The rights conferred on Agent by this Agreement shall continue after Agent has ceased to be a director, officer, employee or
other agent of the Corporation or to serve at the request of the Corporation as a director, officer, employee or other agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, and shall inure to the
benefit of Agent’s heirs, executors and administrators. 
 (b) The Corporation shall require any successor (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Corporation, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the
Corporation would be required to perform if no such succession had taken place. 
 15. Separability. Each of the
provisions of this Agreement is a separate and distinct agreement and independent of the others, so that if any provision hereof shall be held to be invalid or unenforceable for any reason, such invalidity or unenforceability shall not affect the
validity or enforceability of the other provisions hereof. Furthermore, if this Agreement shall be invalidated in its entirety on any ground, then the Corporation shall nevertheless indemnify Agent to the fullest extent provided by the Charter, the
Bylaws, the DGCL or any other applicable law. 
 16. Governing Law. This Agreement shall be governed by, and construed
and enforced in accordance with, the laws of the State of Delaware, without regard to its principles of conflicts of laws. The Corporation and Agent hereby irrevocably and unconditionally (i) agree that any action or proceeding arising out of
or in connection with this Agreement may be brought in the Delaware Court of Chancery, (ii) consent to submit to the jurisdiction of the Delaware Court of Chancery for purposes of any action or proceeding arising out of or in connection with
this Agreement, (iii) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court of Chancery, and (iv) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in
the Delaware Court of Chancery has been brought in an improper or inconvenient forum.
