i.      Authorization . Purchaser represents and warrants to the Company that: (a) Purchaser has all requisite legal and corporate or other power and capacity and has taken all requisite corporate or other action to execute and deliver this Agreement, to purchase the Securities and to carry out and perform all of its obligations under this Agreement; and (b) this Agreement constitutes the legal, valid and binding obligation of the Purchaser, enforceable against the Purchaser in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization or similar laws relating to or affecting the enforcement of creditors’ rights generally and (ii) as limited by equitable principles generally.

ii.      Investment Experience; Access to Information . At the time such Purchaser was offered the Securities, it was, and as of the date hereof it is, and on each date on which it exercises any Initial Warrants and, if applicable, any Option Warrants, it will be either: (i) an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act or (ii) a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act. Purchaser is aware of the Company’s business affairs and financial condition and has had access to and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Purchaser has such business and financial experience as is required to give it the capacity to protect its own interests in connection

with the purchase of the Securities. Purchaser acknowledges that it has had the opportunity to review the Company’s filings with the Commission and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities ; (ii) access to information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed decision with respect to its acquisition of the Shares and the Initial Warrant (and, if applicable, the Option Warrant) .

iii.      Investment Intent . Each Major Purchaser is purchasing the Initial Warrant (and, if applicable, the Option Warrant) for its own account, for investment purposes only, and not with a present view to, or for, resale, distribution or fractionalization thereof, in whole or in part, within the meaning of the Securities Act. Each Major Purchaser understands that its acquisition of the Initial Warrant (and, if applicable, the Option Warrant) has not been registered under the Securities Act or registered or qualified under any state securities law in reliance on specific exemptions therefrom, which exemptions may depend upon, among other things, the bona fide nature of each Major Purchaser’s investment intent as expressed herein. Each Major Purchaser will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) the Initial Warrant (and, if applicable, the Option Warrant) or the Warrant Shares except in compliance with the Securities Act and the rules and regulations promulgated thereunder.

iv.      Reliance on Exemptions; Registration or Exemption Requirements . Each Major Purchaser understands that the Initial Warrants (and, if applicable, the Option Warrants) being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and each Major Purchaser’s compliance with, the representations, warranties, agreements, acknowledgements and understandings of each Major Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of each Major Purchaser to acquire the Initial Warrants (and, if applicable, the Option Warrants) . Each Major Purchaser further acknowledges and understands that the Initial Warrant (and, if applicable, the Option Warrant) and the Warrant Shares may not be resold or otherwise transferred except in a transaction registered under the Securities Act or unless an exemption from such registration is available.

v.      Dispositions .

(i)      Each Major Purchaser will not, prior to the effectiveness of the Resale Registration Statement (as defined below), if then prohibited by law or regulation: (i) sell, offer to sell, solicit offers to buy, dispose of, loan, pledge or grant any right with respect to (collectively, a “ Disposition ”) the Initial Warrant (and, if applicable, the Option Warrant) or the

Warrant Shares; or (ii) engage in any hedging or other transaction which is designed or could reasonably be expected to lead to or result in a Disposition of the Initial Warrant (and, if applicable, the Option Warrant) or the Warrant Shares by the Major Purchaser or an affiliate.

(ii)      As of the Initial Closing Date, each Purchaser has not directly or indirectly, nor has any person acting on behalf of or pursuant to any understanding with the Purchaser, engaged in any purchases or sales of the Company’s securities (including, without limitation, any Short Sales involving the Company’s securities) since the time that the Purchaser was first contacted by the Company or any other person regarding the transactions contemplated hereby. Each Purchaser covenants that neither it nor any person acting on its behalf or pursuant to any understanding with it will engage in any purchases or sales of the Company’s securities (including, without limitation, any Short Sales involving the Company’s securities) prior to the time that the transactions contemplated by this Agreement are publicly disclosed.

vi.      No Legal, Tax or Investment Advice . Purchaser has independently evaluated the merits of its decision to purchase Securities pursuant to this Agreement. Purchaser understands that nothing in this Agreement or any other materials presented to Purchaser in connection with the purchase and sale of the Securities constitutes legal, tax or investment advice. Purchaser has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Securities .

vii.      Confidentiality . Purchaser will hold in confidence all information concerning this Agreement and the sale and issuance of the Securities until the Company has made a public announcement concerning this Agreement and the sale and issuance of the Securities.

viii.      Governmental Review . Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed upon or made any recommendation or endorsement of the Securities.

ix.      Legend .

(i)      Each Major Purchaser understands that the Initial Warrant (and, if applicable, the Option Warrant) and the Warrant Shares shall bear a restrictive legend in substantially the following form (and a stop transfer order may be placed against transfer of the certificates for the Initial Warrant, Optional Warrant and the Warrant Shares):

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR IN ANY OTHER JURISDICTION. THE SECURITIES REPRESENTED HEREBY MAY NOT BE OFFERED, SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER APPLICABLE SECURITIES LAWS UNLESS OFFERED, SOLD OR

TRANSFERRED PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS.”

x.      Beneficial Ownership . Immediately prior to the Initial Closing, Purchaser, together with its affiliates and any other persons acting as a group together with the Purchaser and any of its affiliates, beneficially owned the number of shares of Common Stock set forth on such Purchaser’s signature page attached hereto (as such ownership is calculated pursuant to the rules of Nasdaq).

xi.      Foreign Investors . If Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Code), Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Securities or any use of this Agreement, including (a) the legal requirements within its jurisdiction for the purchase of the Securities , (b) any foreign exchange restrictions applicable to such purchase or acquisition, (c) any government or other consents that may need to be obtained, and (d) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Securities . The Purchaser’s subscription and payment for and continued beneficial ownership of the Securities will not violate any applicable securities or other laws of the Purchaser’s jurisdiction.

Loss resulted or (iii) a Major Purchaser sold Registrable Shares in violation of such Major Purchasers’ covenant contained in Section 4.4 of this Agreement.

ii.      The Major Purchasers agree, severally and not jointly, to indemnify and hold harmless the Company (and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each officer of the Company who signs the Resale Registration Statement and each director of the Company), from and against any losses, claims, damages or liabilities to which the Company (or any such officer, director or controlling person) may become subject (under the Securities Act or otherwise), insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, any material breach of this Agreement by the Major Purchasers or any untrue statement or alleged untrue statement of a material fact contained in the Resale Registration Statement or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading in each case, on the effective date thereof, if, and to the extent, such untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information furnished by or on behalf of the Major Purchasers specifically for use in preparation of the Resale Registration Statement, and the Major Purchasers, severally and not jointly, will reimburse the Company (and each of its officers, directors or controlling persons) for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that in no event shall any indemnity under this Section 4.3(ii) be greater in amount than the dollar amount of the proceeds received by the Major Purchasers upon the sale of such Registrable Shares.

iii.      Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying person pursuant to this Section 4.3, such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, and, subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person and such indemnifying person shall have been notified thereof, such indemnifying person shall be entitled to participate therein, and, to the extent that it shall wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof, such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate in the reasonable judgment of the indemnified person for the same counsel to represent both the indemnified person and such indemnifying person or any affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel at the expense of such indemnifying person; provided, further, that no indemnifying person shall be responsible for the fees and expense of more than one separate counsel for all indemnified parties. The indemnifying party shall not settle an action without the consent of the indemnified party, which consent shall not be unreasonably withheld.

iv.      If after proper notice of a claim or the commencement of any action against the indemnified party, the indemnifying party does not choose to participate, then the indemnified party shall assume the defense thereof and upon written notice by the indemnified party requesting advance payment of a stated amount for its reasonable defense costs and expenses, the indemnifying party shall advance payment for such reasonable defense costs and expenses (the “ Advance Indemnification Payment ”) to the indemnified party. In the event that the indemnified party’s actual defense costs and expenses exceed the amount of the Advance Indemnification Payment, then upon written request by the indemnified party, the indemnifying party shall reimburse the indemnified party for such difference; in the event that the Advance Indemnification Payment exceeds the indemnified party’s actual costs and expenses, the indemnified party shall promptly remit payment of such difference to the indemnifying party.

v.      If the indemnification provided for in this Section 4.3 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other, as well as any other relevant equitable considerations; provided , that in no event shall any contribution by an indemnifying party hereunder be greater in amount than the dollar amount of the proceeds received by such indemnifying party upon the sale of such Registrable Shares.

Each Major Purchasers acknowledge that there may be times when the Company must suspend the use of the prospectus forming a part of the Resale Registration Statement until such time as an amendment to the Resale Registration Statement has been filed by the Company and declared effective by the Commission, or until such time as the Company has filed an appropriate report with the Commission pursuant to the Exchange Act. Each Major Purchaser hereby covenants that it will not sell any Registrable Shares pursuant to said prospectus during the period commencing at the time at which the Company gives the Major Purchasers notice of the suspension of the use of said prospectus and ending at the time the Company gives the Major Purchasers notice that the Major Purchasers may thereafter effect sales pursuant to said prospectus; provided, that such suspension periods shall in no event exceed 30 days in any 12 month period and that, in the good faith judgment of the Company’s Board of Directors, the Company would, in the absence of such delay or suspension hereunder, be required under state or federal securities laws to disclose any corporate development, a potentially significant transaction or event involving the Company, or any negotiations, discussions, or proposals directly relating thereto, in either case the disclosure of which would reasonably be expected to have a material adverse effect upon the Company or its stockholders; provided further, that the Company may suspend the use of the prospectus forming a part of the Resale Registration Statement to the extent necessary to file any post-effective amendment to the Resale Registration Statement in order to amend the table of selling stockholders within the Resale Registration Statement to reflect transfers of the Registrable Shares.

4.5      Termination of Obligations . The obligations of the Company pursuant to Section 4.2 hereof shall cease and terminate, with respect to any Registrable Shares, upon the earlier to occur of (a) such time such Registrable Shares have been resold, or (b) such time as such Registrable Shares no longer remain Registrable Shares pursuant to Section 4.1(ii) hereof.

Ladies and Gentlemen:

Introductory . Cidara Therapeutics, Inc., a Delaware corporation (the “ Company ”), hereby agrees to issue and sell up to an aggregate of $120,000,000 of registered securities of the Company, including registered shares (the “ Shares ”) of the Company’s common stock, par value $0.0001 per share (the “ Common Stock ”), registered shares of the Company’s preferred stock, par value $0.0001 per share (the “ Preferred Stock ”) and the shares of Common Stock issuable upon conversion of the Preferred Stock (the “ Conversion Shares ”), and the Company hereby agrees to issue and sell unregistered warrants to purchase Common Stock (the “ Warrants ”), and the shares of Common Stock underlying the Warrants (together with the Shares, the Preferred Stock, the Conversion Shares and the Warrants, the “ Securities ”) directly to various investors (each, an “ Investor ” and, collectively, the “ Investors ”) through the several placement agents listed on Schedule A hereto (the “ Placement Agents ”). Citigroup Global Markets Inc. (“ Citigroup ”) and Cantor Fitzgerald & Co. (“ Cantor ”) have agreed to act as representatives (the “ Representatives ”) of the several placement agents listed Schedule A hereto, and may retain other brokers or dealers to act as sub-agents or selected-dealers on its behalf in connection with the Offering (as defined below).

The Company hereby confirms its agreement with each Placement Agent as follows:

Section 1.     Agreement to Act as Placement Agent .

(a) On the basis of the representations, warranties and agreements of the Company herein contained, and subject to all the terms and conditions of this Agreement, the Placement Agents shall be the exclusive Placement Agents in connection with the offering and sale by the Company of the Securities from time to time pursuant to (i) the Company’s shelf registration statement on Form S-3 (File No. 333-211472) and (ii) an exemption from the registration requirements of Section 5 of the Securities Act contained in Section 4(a)(2) thereof and/or Regulation D thereunder, with the terms of such offering (the “ Offering ”) to be subject to market conditions and negotiations between the Company and the prospective Investors. The Placement Agents will act on a reasonable best efforts basis and the Company agrees and acknowledges that there is no guarantee of the successful placement of the Securities, or any

portion thereof, in the prospective Offering. Under no circumstances will the Placement Agents or any of their respective “Affiliates” (as defined below) be obligated to underwrite or purchase any of the Securities for its own account or otherwise provide any financing. The Placement Agents shall act solely as the Company’s agent and not as principal. The Placement Agents shall have no authority to bind the Company with respect to any prospective offer to purchase any Securities and the Company shall have the sole right to accept offers to purchase the Securities and may reject any such offer, in whole or in part. Subject to the terms and conditions hereof, payment of the purchase price for, and delivery of, the Securities shall be made at one or more closings, as set forth in that certain Subscription Agreement, dated as of May 21, 2018, among the Company and the Investors (the “ Subscription Agreement ”). The Initial Closing, the Second Closing, the Optional Closing and the Second Shortfall Closing, in each case as defined in the Subscription Agreement, are referred to collectively herein as a “ Closing ” and the date on which each Closing occurs is referred to herein as a “ Closing Date .” As compensation for services rendered, the Company shall pay to the Placement Agents the fees and expenses set forth below:

(i) A cash fee equal to an aggregate of $1,950,000 at the Initial Closing (as defined in the Subscription Agreement).

(ii) Subject to compliance with FINRA Rule 5110(f)(2)(D), the Company also agrees to reimburse Citigroup and Cantor for the reasonable, out-of-pocket expenses, set forth in Section 6 below. Such reimbursement shall be payable immediately upon (but only in the event of) a Closing of the Offering.

(b) The term of the exclusive engagement of the Placement Agents will be until the earlier of (i) the completion of the Offering, (ii) the date that is the twelfth trading day following the date that the Company publically announces topline data from its STRIVE Part B study, or (iii) December 31, 2019; provided, however, that a party hereto may terminate the engagement with respect to itself at any time upon 10 days written notice to the other parties. Notwithstanding anything to the contrary contained herein, the provisions concerning confidentiality, indemnification and contribution contained herein and the Company’s obligations contained in the indemnification provisions will survive any expiration or termination of this Agreement, and the Company’s obligation to pay fees actually earned and payable and to reimburse expenses actually incurred and reimbursable pursuant to Section 1 hereof and which are permitted to be reimbursed under FINRA Rule 5110(f)(2)(D), will survive any expiration or termination of this Agreement. Nothing in this Agreement shall be construed to limit the ability of the Placement Agents or their respective Affiliates to pursue, investigate, analyze, invest in, or engage in investment banking, financial advisory or any other business relationship with Persons (as defined below) other than the Company. As used herein (i) “ Person ” means an individual or corporation, partnership, trust, incorporated or unincorporated association, joint venture, limited liability company, joint stock company, government (or an agency or subdivision thereof) or other entity of any kind and (ii) “ Affiliate ” means any Person that, directly or indirectly through one or more intermediaries, controls or is controlled by or is under common control with a Person as such terms are used in and construed under Rule 405 under the Securities Act of 1933, as amended (the “ Securities Act ”).

Section 2.     Representations, Warranties and Covenants of the Company .

The Company hereby represents, warrants and covenants to each Placement Agent, as of the date of this Agreement and as of the Initial Closing Date (as defined in the Subscription Agreement) as follows:

(a) Securities Law Filings . The Company has prepared and filed with the Securities and Exchange Commission (the “ Commission ”) a shelf registration statement on Form S-3, File No. 333-211472, including a base prospectus (the “ Base Prospectus ”) to be used in connection with the

offering and sale of the Shares, Preferred Stock and Conversion Shares. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, in the form in which it became effective under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “ Securities Act ”), including all documents incorporated or deemed to be incorporated by reference therein and any information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430A or Rule 430B under the Securities Act, is called the “ Registration Statement. ” Any registration statement filed by the Company pursuant to Rule 462(b) under the Securities Act in connection with the offer and sale of the Shares, Preferred Stock and Conversion Shares is called the “ Rule 462(b) Registration Statement, ” and from and after the date and time of filing of any such Rule 462(b) Registration Statement the term “ Registration Statement ” shall include the Rule 462(b) Registration Statement. Following the determination of pricing among the Company and the Investors, the Company will file with the Commission pursuant to Rule 424(b) under the Securities Act, a prospectus supplement to the Base Prospectus relating to the terms of the Offering and of the Securities and the plan of distribution thereof (the “ Prospectus Supplement ” and, together with the Base Prospectus, the “ Prospectus ”) and will advise the Placement Agents of all further information (financial and other) with respect to the Company required to be set forth therein. References herein to the Prospectus shall refer to both the Prospectus Supplement and the Base Prospectus components of such prospectus. Any reference in this Agreement to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the documents incorporated by reference therein (the “ Incorporated Documents ”), if any, which were filed under the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), at any given time, as the case may be; and any reference in this Agreement to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be, deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information that is “contained,” “included,” “described,” “referenced,” “set forth” or “stated” in the Registration Statement, the Base Prospectus or the Prospectus Supplement (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information that is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus Supplement, as the case may be.

(b) Compliance with Registration Requirements . The Registration Statement has become effective under the Securities Act. The Company has complied, to the Commission’s satisfaction with all requests of the Commission for additional or supplemental information, if any. No stop order suspending the effectiveness of the Registration Statement is in effect and no proceedings for such purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated or threatened by the Commission. At the time the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 (the “ Annual Report ”) was filed with the Commission, or, if later, at the time the Registration Statement was originally filed with the Commission, the Company met the then-applicable requirements for use of Form S-3 under the Securities Act. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Base Prospectus and the Prospectus Supplement, at the time they were or hereafter are filed with the Commission, or became effective under the Exchange Act, as the case may be, complied and will comply in all material respects with the requirements of the Exchange Act.

(c) Assurances . The Registration Statement, as amended, (and any further documents to be filed with the Commission) contains all exhibits and schedules as required by the Securities Act. Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective,

complied in all material respects with the Securities Act and the Exchange Act and did not and, as amended or supplemented, if applicable, will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Base Prospectus, and the Prospectus Supplement, each as of its respective date, comply or will comply in all material respects with the Securities Act and the Exchange Act and the rules and regulations promulgated thereunder. Each of the Base Prospectus and the Prospectus Supplement, as amended or supplemented, did not and will not contain as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The Incorporated Documents, if any, when they were filed with the Commission, conformed in all material respects to the requirements of the Exchange Act and the rules and regulations promulgated thereunder, and none of such documents, when they were filed with the Commission, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein (with respect to Incorporated Documents incorporated by reference in the Base Prospectus or Prospectus Supplement), in light of the circumstances under which they were made not misleading; and any further documents so filed and incorporated by reference in the Base Prospectus or Prospectus Supplement, when such documents are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act and the rules and regulations promulgated thereunder, as applicable, and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. No post-effective amendment to the Registration Statement reflecting any facts or events arising after the date thereof which represent, individually or in the aggregate, a fundamental change in the information set forth therein is required to be filed with the Commission. There are no documents required to be filed with the Commission in connection with the transaction contemplated hereby that (x) have not been filed as required pursuant to the Securities Act or (y) will not be filed within the requisite time period. There are no contracts or other documents required to be described in the Base Prospectus, or Prospectus Supplement, or to be filed as exhibits or schedules to the Registration Statement, that have not been described or filed as required. The Company is eligible to use free writing prospectuses in connection with the Offering pursuant to Rules 164 and 433 under the Securities Act. Any free writing prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or on behalf of or used by the Company complies or will comply in all material respects with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. The Company will not, without the prior consent of the Representatives, prepare, use or refer to, any free writing prospectus, other than any free writing prospectus listed on Schedule C hereto.

(d) Offering Materials . The Company has delivered, or will as promptly as practicable deliver, to the Placement Agents complete conformed copies of the Registration Statement and of each consent and certificate of experts, as applicable, filed as a part thereof, and conformed copies of the Registration Statement (without exhibits), the Base Prospectus, and the Prospectus Supplement, as amended or supplemented, in such quantities and at such places as each Placement Agent reasonably requests. Neither the Company nor any of its directors and officers has distributed and none of them will distribute, prior to the Initial Closing Date, any offering material in connection with the offering and sale of the Securities other than the Base Prospectus, the Prospectus Supplement, the Registration Statement, copies of the documents incorporated by reference therein and any other materials permitted by the Securities Act.

(e) Representations and Warranties Incorporated by Reference . Each of the representations and warranties made pursuant to the Subscription Agreement is hereby incorporated herein by reference (as though fully restated herein) and is hereby made to, and in favor of, the Placement Agents.

Section 3.     Delivery and Payment . Each Closing shall occur at the offices of Citigroup (or at such other place as shall be agreed upon by Citigroup and the Company). Subject to the terms and conditions hereof, at each Closing payment of the purchase price for the Securities sold on such Closing Date shall be made by Federal Funds wire transfer, against delivery of such Securities, and such Securities shall be registered in such name or names and shall be in such denominations, as the Placement Agents may request at least one business day before such Closing Date. Deliveries of the documents with respect to the purchase of the Securities, including the Subscription Agreement, shall be made at the offices of Citigroup. All actions taken at a Closing shall be deemed to have occurred simultaneously.

Section 4.     Covenants and Agreements of the Company .

The Company further covenants and agrees with each Placement Agent as follows:

(a)      Registration Statement Matters . The Company will advise the Placement Agents promptly after it receives notice thereof of the time when any amendment to the Registration Statement has been filed or becomes effective or any supplement to any Prospectus Supplement or any amended Prospectus Supplement has been filed and will furnish each Placement Agent with copies thereof. The Company will file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 14 or 15(d) of the Exchange Act subsequent to the date of any Prospectus Supplement and for so long as the delivery of a prospectus is required in connection with the Offering. The Company will advise the Placement Agents, promptly after it receives notice thereof (i) of any request by the Commission to amend the Registration Statement or to amend or supplement any Prospectus Supplement or for additional information, and (ii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or any order directed at any Incorporated Document, if any, or any amendment or supplement thereto or any order preventing or suspending the use of the Base Prospectus or any Prospectus Supplement or any amendment or supplement thereto or any post-effective amendment to the Registration Statement, of the suspension of the qualification of the Shares, Preferred Stock or Conversion Shares for offering or sale in any jurisdiction, of the institution or threatened institution of any proceeding for any such purpose, or of any request by the Commission for the amending or supplementing of the Registration Statement or a Prospectus Supplement or for additional information. The Company shall use its best efforts to prevent the issuance of any such stop order or prevention or suspension of such use. If the Commission shall enter any such stop order or order or notice of prevention or suspension at any time, the Company will use its best efforts to obtain the lifting of such order at the earliest possible moment, or will file a new registration statement and use its best efforts to have such new registration statement declared effective as soon as practicable. Additionally, the Company agrees that it shall comply with the provisions of Rules 424(b), 430A, 430B and 430C, as applicable, under the Securities Act, including with respect to the timely filing of documents thereunder, and will use its reasonable efforts to confirm that any filings made by the Company under such Rule 424(b) are received in a timely manner by the Commission.

(b)      Blue Sky Compliance . The Company will cooperate with the Placement Agents and the Investors in endeavoring to qualify the Securities for sale under the securities laws of such jurisdictions (United States and foreign) as the Placement Agents and the Investors may reasonably request and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Company shall not be required to qualify as a foreign corporation or to file

a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent, and provided further that the Company shall not be required to produce any new disclosure document other than a Prospectus Supplement. The Company will, from time to time, prepare and file such statements, reports and other documents as are or may be required to continue such qualifications in effect for so long a period as the Placement Agents may reasonably request for distribution of the Securities. The Company will advise the Placement Agents promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities, as applicable, for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its best efforts to obtain the withdrawal thereof at the earliest possible moment.

(c)      Amendments and Supplements to a Prospectus Supplement and Other Matters . The Company will comply with the Securities Act and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Securities as contemplated in this Agreement, the Incorporated Documents and any Prospectus Supplement. If during the period in which a prospectus is required by law to be delivered in connection with the distribution of Securities contemplated by the Incorporated Documents or any Prospectus Supplement (the “ Prospectus Delivery Period ”), any event shall occur as a result of which, in the judgment of the Company or in the opinion of the Placement Agents, it becomes necessary to amend or supplement the Incorporated Documents or any Prospectus Supplement in order to make the statements therein, in the light of the circumstances under which they were made, as the case may be, not misleading, or if it is necessary at any time to amend or supplement the Incorporated Documents or any Prospectus Supplement or to file under the Exchange Act any Incorporated Document to comply with any law, the Company will promptly prepare and file with the Commission, and furnish at its own expense to the Placement Agents and to dealers, an appropriate amendment to the Registration Statement or supplement to the Registration Statement, the Incorporated Documents or any Prospectus Supplement that is necessary in order to make the statements in the Incorporated Documents and any Prospectus Supplement as so amended or supplemented, in the light of the circumstances under which they were made, as the case may be, not misleading, or so that the Registration Statement, the Incorporated Documents or any Prospectus Supplement, as so amended or supplemented, will comply with law. Before amending the Registration Statement or supplementing the Incorporated Documents or any Prospectus Supplement in connection with the Offering, the Company will furnish the Placement Agents with a copy of such proposed amendment or supplement and will not file any such amendment or supplement to which the Placement Agents reasonably object.

(d)      Copies of any Amendments and Supplements to a Prospectus Supplement . The Company will furnish each Placement Agent, without charge, during the period beginning on the date hereof and ending on the later of the last Closing Date of the Offering, as many copies of the Incorporated Documents and any Prospectus Supplement and any amendments and supplements thereto (including any Incorporated Documents, if any) as each Placement Agent may reasonably request.

(e)      Free Writing Prospectus . Except as listed on Schedule C hereto, the Company covenants that it will not, unless it obtains the prior written consent of the Representatives, make any offer relating to the Securities that would constitute a “ free writing prospectus ” (as defined in Rule 405 of the Securities Act) required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the Securities Act. In the event that the Placement Agents expressly consent in writing to any such free writing prospectus (a “ Permitted Free Writing Prospectus ”), the Company covenants that it shall (i) treat each Permitted Free Writing Prospectus as a “free writing prospectus”, and (ii) comply with the

requirements of Rule 164 and 433 of the Securities Act applicable to such Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(f)      Transfer Agent . The Company will maintain, at its expense, a registrar and transfer agent for the Common Stock.

(g)      Earnings Statement . As soon as practicable and in accordance with applicable requirements under the Securities Act, but in any event not later than 18 months after the last Closing Date, the Company will make generally available to its security holders and to the Placement Agents an earnings statement, covering a period of at least 12 consecutive months beginning after the last Closing Date, that satisfies the provisions of Section 11(a) and Rule 158 under the Securities Act.

(h)      Periodic Reporting Obligations . During the Prospectus Delivery Period, the Company will duly file, on a timely basis, with the Commission and the Nasdaq Global Market (the “ Nasdaq ”) all reports and documents required to be filed under the Exchange Act within the time periods and in the manner required by the Exchange Act.

(i)      Third Party Beneficiary . The Company agrees that each Placement Agent may rely upon, and each is a third party beneficiary of, the representations and warranties, and applicable covenants, set forth in the Subscription Agreement.

(j)      No Manipulation of Price .  The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

(k)      Acknowledgment . The Company acknowledges that any advice given by the Placement Agents to the Company is solely for the benefit and use of the Board of Directors of the Company and may not be used, reproduced, disseminated, quoted or referred to, without the prior written consent of the Representatives.

Section 5.    Conditions of the Obligations of the Placement Agents . The respective obligations of the Placement Agents hereunder shall be subject to the accuracy of the representations and warranties on the part of the Company set forth in Section 2 hereof as of the date hereof and as of each Closing Date as though then made, to the timely performance by the Company of its covenants and other obligations hereunder, and to each of the following additional conditions:

Indemnification

In connection with the engagement of the Placement Agents to assist the Company as described in this Placement Agency Agreement, including modifications or future additions to such engagement and related activities prior to the date of this Agreement (the “engagement”), the Company agrees that it will indemnify and hold harmless the Placement Agents and their respective affiliates and their respective directors, officers, partners, members, agents and employees and each other person controlling any Placement Agent or any of their respective affiliates (each, an “indemnified party”), to the full extent lawful, from and against any losses, expenses, claims or proceedings (collectively, “losses”) (i) related to or arising out of (A) the contents of oral or written information related to this Agreement, the Subscription Agreement, or any transaction or conduct in connection therewith provided by the Company, its affiliates and their respective employees or its other agents, which information either the Company or any Placement Agent provides to any actual or potential buyers, sellers, investors or offerees; (B) any breach of a representation, warranty or covenant by the Company contained in this Agreement; or (C) any other action or failure to act by the Company, its affiliates and their respective employees or its other agents or by the Placement Agents or any indemnified party in accordance with and at the Company’s request or with the Company’s consent, or (ii) otherwise related to or arising out of this Agreement or any transaction or conduct in connection therewith, including, without limitation the Offering, except that this clause (ii) shall not apply with respect to any losses that are finally judicially determined to have resulted primarily and directly from the gross negligence or willful misconduct of such indemnified party. The Company further agrees that no indemnified party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Company or any of its affiliates, creditors or security holders for or in connection with the engagement or any actual or proposed transactions or other conduct in connection therewith except for losses incurred by the Company that are finally judicially determined to have resulted primarily and directly from the gross negligence or willful misconduct of such indemnified party.

In the event that the foregoing indemnity is unavailable to any indemnified party for any reason (other than pursuant to the exception contained in the first paragraph hereof), the Company agrees to contribute to any losses related to or arising out of the engagement or any transaction or conduct in connection therewith as follows. For losses referred to in clause (i) of the preceding paragraph, the Placement Agents and the Company shall contribute in such proportion as is appropriate to reflect the relative benefits received (or anticipated to be received) by the Placement Agents, on the one hand, and by the Company and its security holders, on the other hand, from the actual or proposed transaction arising in connection with the engagement. For any other losses, and for losses referred to in clause (i) of the preceding paragraph if the allocation provided by the immediately preceding sentence is unavailable for any reason, the Placement Agents and the Company shall contribute in such proportion as is appropriate to reflect not only the relative benefits as set forth above, but also the relative fault of the Placement Agents and the Company in connection with the statements, omissions or other conduct that resulted in such losses, as well as any other relevant equitable considerations. Benefits received (or anticipated to be received) by the Company and its security holders shall be deemed to be equal to the aggregate cash consideration and value of securities or any other property payable, issuable, exchangeable or transferable in such transaction or proposed transaction, and benefits received by the Placement Agents shall be deemed to be equal to the compensation paid by the Company to the Placement Agents in connection with the engagement (exclusive of amounts paid for reimbursement of expenses under this agreement, including this Schedule B, and amounts paid under this Schedule B). Relative fault shall be determined by reference to, among other things, whether any alleged untrue statement or omission or any other alleged conduct relates to information provided by the Company or other conduct by the Company (or its employees or other agents), on the one hand, or by the Placement Agents, on the other hand. The Placement

Agents and the Company agree that it would not be just and equitable if contribution were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding anything to the contrary above (other than pursuant to the exception contained in the first paragraph hereof), in no event shall any Placement Agent be responsible under this paragraph for any amounts in excess of the amount of the compensation actually paid by the Company to such Placement Agent in connection with the engagement (exclusive of amounts paid for reimbursement of expenses under this agreement, including this Schedule B, and amounts paid under this Schedule B).

The Company agrees that it will not, without the prior written consent of the Placement Agents, settle any pending or threatened claim or proceeding related to or arising out of the engagement or any actual or proposed transactions or other conduct in connection therewith (whether or not the Placement Agents or any indemnified party is a party to such claim or proceeding) unless such settlement includes a provision unconditionally releasing the Placement Agents and each other indemnified party from all liability in respect of claims by any releasing party related to or arising out of the engagement or any transactions or conduct in connection therewith and does not contain an admission of fault, culpability or failure to act by or on behalf of such indemnified party. The Placement Agents will not settle any claims or actions for which it seeks indemnification or contribution hereunder without the consent of the Company, not to be unreasonably withheld. The Company will also promptly reimburse each indemnified party for all reasonable out of pocket expenses (including reasonable counsel fees and expenses) as they are incurred by such indemnified party in connection with investigating, preparing for, defending, or providing evidence in, any pending or threatened claim or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the Placement Agents or any indemnified party is a party to such claim or proceeding) or in enforcing this Schedule B.

The foregoing provisions are in addition to any rights the Company or the Placement Agents may have at common law or otherwise and shall be binding on and inure to the benefit of any successors, assigns, and personal representatives of the Company and each indemnified party. Solely for purposes of enforcing the provisions of this Schedule B, the Company hereby consents to personal jurisdiction, service of process and venue in any court in which any claim or proceeding that is subject to this Schedule B is brought against the Placement Agents. The provisions of this Schedule B shall remain in full force and effect notwithstanding (i) any investigation made by or on behalf of the Placement Agents or (ii) the completion or termination of the engagement.
