 E. Additionally, Companies have requested that Wells Fargo (i) forbear from exercising any rights or
remedies based on the Designated Events of Default (including, but not limited to, refusing to make Advances, accelerating any Indebtedness, foreclosing on any Collateral or filing a petition for bankruptcy) for the temporary period of time set

subject in each case to the terms and conditions of this Amendment. 
 NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements herein contained, it is agreed as follows: 
 1. Temporary Forbearance. Subject to the satisfaction of the terms and
conditions set forth herein, until that date (the “Forbearance Termination Date”) which is the earliest to occur of (a) 5:00 p.m. Pacific time on July 31, 2009; (b) the date of the occurrence of any Event of Default

to exercise or enforce under the terms of the Loan Documents by reason of the occurrence of the Designated Events of Default; provided that such forbearance shall not act as a waiver of Wells Fargo’s right to enforce all claims, rights,
and remedies from time to time on or after the Forbearance Termination Date. Furthermore, nothing contained herein shall be construed as requiring Wells Fargo to extend the Forbearance Termination Date. Companies acknowledge and agree that Wells
Fargo has not waived, and by entering into this Amendment Wells Fargo is not waiving, the Designated Events of Default or any Forbearance Period Financial Covenant Defaults that may occur on or prior to July 31, 2009.

(the “Line of Credit”) and make Advances and repayments thereunder in the same manner and in accordance with the same terms as those governing the Loan Documents applicable thereto (including, but not limited to, satisfaction of all
conditions precedent in Article III of the Credit Agreement) as though the Designated Events of Default do not exist. It is expressly acknowledged and agreed by Companies that any election by Wells Fargo to continue administering the Line of Credit
and making Advances as provided for hereby from the date of this Amendment and ending on the Forbearance Termination Date shall not in any manner be deemed to prejudice Wells Fargo or act as a waiver of its otherwise applicable rights and remedies,

the requisite power and authority to own and use its properties and assets and to carry on its business as currently conducted. Neither the Company nor any Subsidiary is in violation or default of any of the provisions of its respective certificate
or articles of incorporation, bylaws or other organizational or charter documents. Each of the Company and the Subsidiaries is duly qualified to conduct business and is in good standing as a foreign corporation or other entity in each jurisdiction
in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, would not have or reasonably be expected to result in
(i) a material adverse effect on the legality, validity or enforceability of any Transaction Document, (ii) a material adverse effect on the results of operations, assets, business, prospects or condition (financial or otherwise) of the
Company and the Subsidiaries, taken as a whole, or (iii) a material adverse effect on the Company’s ability to perform in any material respect on a timely basis its obligations under any Transaction Document (any of (i), (ii) or
(iii), a “Material Adverse Effect”) and no Proceeding has been instituted in any such jurisdiction revoking, limiting or curtailing or seeking to revoke, limit or curtail such power and authority or qualification. 
 (c) Authorization; Enforcement. The Company has the requisite corporate power and authority to enter into and to consummate the transactions

connection with the Required Approvals. Each Transaction Document has been (or upon delivery will have been) duly executed by the Company and, when delivered in accordance with the terms hereof and thereof, will constitute the valid and binding
obligation of the Company

enforceable against the Company in accordance with its terms except (i) as limited by general equitable principles and applicable bankruptcy,

and will not (i) conflict with or violate any provision of the Company’s or any Subsidiary’s certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, or constitute a
default (or an event that with notice or lapse of time or both would become a default) under, result in the creation of any Lien upon any of the properties or assets of the Company or any Subsidiary, or give to others any rights of termination,
amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument (evidencing a Company or Subsidiary debt or otherwise) or other understanding to which the Company
or any Subsidiary is a party or by which any property or asset of the Company or any Subsidiary is bound or affected, or (iii) subject to the Required Approvals, conflict with or result in a violation of any law, rule, regulation, order,
judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or a Subsidiary is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company
or a Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as would not have or reasonably be expected to result in a Material Adverse Effect.

capital stock, options and other securities of the Company (whether or not presently convertible into or exercisable or exchangeable for shares of capital stock of the Company) has been set forth in the SEC Reports and has changed since the date of

any right to subscribe for or acquire, any shares of Common Stock, or contracts, commitments, understandings or arrangements by which the Company or any Subsidiary is or may become bound to issue additional shares of Common Stock or Common Stock
Equivalents. The issuance and sale of the Securities will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than the Purchasers and the Placement Agent) and will not result in a right of any holder of
Company securities to adjust the exercise, conversion, exchange or reset price under any of such securities. All of the outstanding shares of capital stock of the Company are duly authorized, validly issued, fully paid and nonassessable, have been
issued in compliance with all federal and state securities laws, and none of such outstanding shares was issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities. Except for the Required Approvals, no

other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer does not subject the Company or any of its Subsidiaries to any liability with respect to any of the foregoing matters. The Company
and its Subsidiaries are in compliance with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in

action is taken with respect to any differences. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and designed such disclosure controls and procedures to
ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms.
The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by the Company’s most recently filed periodic report under the Exchange Act
(such date, the “Evaluation Date”). The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures
based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no changes in the Company’s internal control over financial reporting (as such term is defined in the Exchange Act) that has materially affected,
or is reasonably likely to materially affect, the Company’s internal control over financial reporting. 
 (s) Certain Fees.
Except as set forth on Schedule 3.1(s), no brokerage or finder’s fees or commissions are or will be payable by the Company to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person

no obligation with respect to any fees or with respect to any claims made by or on behalf of other Persons for fees of a type contemplated in this Section that may be due in connection with the transactions contemplated by the Transaction Documents.

 (t) Private Placement. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 3.2,

for the Shares and Warrants, will not be or be an Affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. 
 (v) Registration Rights. No Person has any right to cause the Company to effect the registration under the Securities Act of any securities of the Company, other than with respect to the Company’s
continuing obligations to maintain the effectiveness of registration statements filed prior to the date hereof.

compliance with the listing or maintenance requirements of such Trading Market. Except as set forth on Schedule 3.1(w), the Company is, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance with all
such listing and maintenance requirements. 
 (x) Disclosure. All disclosure furnished by or on behalf of the Company to the

 (y) No Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in
Section 3.2, neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances
that would cause this offering of the Shares to be integrated or aggregated with prior offerings by the Company for purposes of the Securities Act or any applicable shareholder approval provisions of any Trading Market on which any of the securities
of the Company are listed or designated. 
 (z) Tax Status. Except for matters that would not, individually or in the aggregate, have
or reasonably be expected to result in a Material Adverse Effect, the Company and each Subsidiary has accurately and timely filed all federal, state and foreign income and franchise tax returns, reports and declarations required by any jurisdiction

fiduciary of the Company (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated thereby and any advice given by any Purchaser or any of their respective representatives or agents in connection with
the Transaction Documents and the transactions contemplated thereby is merely incidental to the Purchasers’ purchase of the Shares and Warrants. The Company further represents to each Purchaser that the Company’s decision to enter into
this Agreement and the other Transaction Documents has been based solely on the independent evaluation of the transactions contemplated hereby by the Company and its representatives. 
 (ee) Regulation M Compliance. The Company has not, and to its knowledge no one acting on its behalf has, (i) taken, directly or

administrative or regulatory proceeding, charge, complaint, or investigation) against the Company or any of its Subsidiaries, and none of the Company or any of its Subsidiaries has received any notice, warning letter or other communication from the
FDA or any other governmental entity, which (i) contests the

 17 

 
hedging and/or trading activities at various times during the period that the Shares are outstanding and (2) such hedging and/or trading activities, if
any, can reduce the value of the existing stockholders’ equity interest in the Company both at and after the time the hedging and/or trading activities are being conducted. The Company acknowledges that such aforementioned hedging and/or
trading activities do not constitute a breach of the Transaction Documents. 
 3.2 Representations and Warranties of the Purchasers. Each Purchaser,
for itself and for no other Purchaser, hereby represents and warrants as of the date hereof and as of the Closing Date to the Company as follows: 
 (a) Organization; Authority. If not a natural person, such Purchaser is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with full right, corporate or partnership

transactions contemplated by this Agreement have been duly authorized by all necessary corporate or similar action on the part of such Purchaser. Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when
delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance with its terms, except (i) as limited by general equitable

acquiring the Securities as principal for its own account and not with a view to or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state or other securities law, has no present
intention of distributing any of such Securities in violation of the Securities Act or any applicable state or other securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the

 (e) General Solicitation. Such Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or other communication
regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or general advertisement.

any Person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly executed any transaction, including Short Sales, in the securities of the Company during the period commencing from the time that such
Purchaser was first contacted by the Company or any third-party acting on behalf of the Company pertaining to the transactions contemplated hereunder until the date hereof (“Discussion Time”). Notwithstanding the foregoing, in the
case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the
portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the
Securities covered by this Agreement. Other than to other Persons party to this Agreement, such Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this
transaction).

 19

or is headquartered or formed, in the case of entities, in the United States, such Purchaser acknowledges that the Company will not issue any Securities in compliance with the laws of any jurisdiction outside of the United States and the Company
makes no representation or warranty that any Securities issued outside of the United States have been offered or sold in compliance with the laws of the jurisdiction into which such Securities were issued. Any Purchaser not a resident of or formed
in the United States warrants to the Company that no filing is required by the Company with any governmental authority in such Purchaser’s jurisdiction in connection with the transactions contemplated hereby. If such Purchaser is domiciled or

requirements within its jurisdiction for the purchase of the Securities, (ii) any foreign exchange restrictions applicable to such purchase, (iii) any governmental or other consents that may need to be obtained and (iv) the income tax
and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Securities. If such Purchaser is domiciled or was formed outside the U.S., such Purchaser’s acquisition of and payment for,
and its continued ownership of the Securities, will not violate any applicable securities or other laws of his, her or its jurisdiction. 
 (l) Acknowledgement. Each Purchaser acknowledges that the Company has relied upon the representations and warranties of the Purchasers set forth in Section 3.2 in its determination that no registration under the Securities Act
is required for the offer and sale of the Securities by the Company to the Purchasers as contemplated by this Agreement. 
 (m)
Acknowledgements Regarding Placement Agent. 
 (i) The Purchaser acknowledges that the Placement Agent is acting as the
exclusive placement agent on a “best efforts” basis for the Securities being offered hereby and will be compensated by the Company for acting in such capacity. The Purchaser represents that (1) the Purchaser has a pre-existing
relationship with the Placement Agent or the Company, (2) the Purchaser was contacted regarding the sale of the Securities by the Placement Agent or the Company (or an authorized agent or representative thereof) with whom the Purchaser agreed
to maintain the confidentiality of the material terms and conditions of the transactions contemplated by the Transaction Documents until such information was publicly disclosed by the Company, and (3) no Securities were offered or sold to it by
means of any form of general solicitation or general advertising. 
 (ii) The Purchaser acknowledges that the Placement Agent
and its directors, officers, employees, representatives and controlling persons have no responsibility for making any independent investigation of the SEC Reports and make no representation or warranty to the Purchaser, express or implied, with
respect to the Company or the Securities or the accuracy, completeness or adequacy of the SEC Reports or any other publicly available information, nor shall any of the foregoing persons be liable for any 

  

 20 

 
loss or damages of any kind resulting from the use of the information contained therein or otherwise supplied to the Purchaser. In addition, the Purchaser
acknowledges that it has not relied on information provided by any of such persons but has conducted its own investigation. 
 (n)
Participation by Interested Parties. The Purchaser acknowledges that (i) Units may be purchased by Affiliates of the Company and other parties that may be interested in the transactions contemplated by this Agreement, and that
(ii) the Purchase Price for such Units, will be counted in determining whether the minimum aggregate Purchase Price of Two Million Dollars ($2,000,000) has been deposited in the Escrow Account, as required by Section 2.3(a)(iv) and
Section 2.3(b)(v). The Purchaser acknowledges that the condition set forth in Section 2.3(a)(iv) and Section 2.3(b)(v) is not designed as a protection to investors, and the Purchaser is not relying on the minimum aggregate Purchase
Price of Two Million Dollars ($2,000,000) as an indication of the merits of the transactions contemplated by this Agreement. 
 ARTICLE IV.

 4.1 Registration; Definitions. 
 (a) No
later than sixty (60) days following the Closing Date (the “Registration Due Date”), the Company shall prepare and file with the Commission a registration statement covering the resale of all of the Registrable Securities (the
“Registration Statement”); provided, however, that if the Registration Due Date falls on a Saturday, Sunday or other day on which the Commission is not open for business, then the Registration Due Date shall be extended to
the next day on which the Commission is open for business. The Registration Statement required hereunder shall be on Form S-1 or any another appropriate form in accordance herewith, in the sole discretion of the Company. Subject to the terms of this
Agreement, the Company shall use its commercially reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as possible after the filing thereof and shall use its commercially reasonable
efforts to keep the Registration Statement continuously effective under the Securities Act until the date when all Registrable Securities covered by the Registration Statement have been sold or may be sold without volume restrictions pursuant to
Rule 144, as determined by the counsel to the Holder (as defined below) pursuant to a written opinion letter to such effect, addressed and acceptable to the Company’s counsel, the Company’s transfer agent and the affected Holders (the
“Effectiveness Period”). 
 (b) In the event the Company fails to file the Registration Statement with the Commission on or
before Registration Due Date, the Company shall pay to each Purchaser, as liquidated damages and not as a penalty, an amount, for each month (or portion of a month) in which such delay shall occur, equal to one percent (1%) of the Purchase
Price paid by each such Purchaser, until the point in time when the Company has filed the Registration Statement with the Commission or the expiration of the Effectiveness Period, whichever occurs first. 
 (c) The term “Registrable Securities” shall mean (i) all Shares sold in the Offering, (ii) the Warrant Shares issuable upon
exercise of all Warrants sold in the Offering, and (iii) any shares of Common Stock issued or issuable upon any stock split, dividend or other distribution, recapitalization or similar event with respect to the foregoing; provided, however,
that securities 

  

 21 

 
shall only be treated as Registrable Securities if and only for so long as they (i) have not been sold (A) pursuant to a registration statement;
(B) to or through a broker, dealer or underwriter in a public distribution or a public securities transaction; and/or (C) in a transaction exempt from the registration and prospectus delivery requirements of the Securities Act under
Section 4(1) thereof so that all transfer restrictions and restrictive legends with respect thereto, if any, are removed upon the consummation of such sale; (ii) are not held by a Holder (as defined below) or a permitted transferee; and
(iii) are not eligible for sale without volume limitations pursuant to Rule 144 (or any successor thereto) under the Securities Act. 
 (d) The term “Holder” shall mean any person owning or having the right to acquire Registrable Securities or any permitted transferee of a Holder. 
 4.2 Registration Procedures; Company. In connection with the Company’s registration obligations set forth in Section 4.1 above, the Company shall: 
 (a) Not less than five (5) business days prior to the filing of the Registration Statement or any related prospectus or any amendment or supplement
thereto (i) furnish to the Holders copies of all such documents proposed to be filed (other than those documents incorporated or deemed incorporated by reference to the extent requested by such Person) which documents will be subject to the
review of such Holders and (ii) cause its officers, directors, counsel and independent certified public accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of respective counsel, to conduct a reasonable
investigation within the meaning of the Securities Act. The Company shall not file the Registration Statement or any such prospectus or any amendments or supplements thereto to which the Holders of a majority of the Registrable Securities shall
reasonably object in good faith, provided that the Company is notified of such objection in writing no later than three (3) business days after the Holders have been so furnished copies of such documents. 
 (b) Prepare and file with the Commission such amendments, including post-effective amendments, to the Registration Statement and the prospectus used in
connection therewith as may be necessary to keep the Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period and prepare and file with the Commission such additional Registration
Statements in order to register for resale under the Securities Act all of the Registrable Securities. 
 (c) Use commercially reasonable
efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of the Registration Statement or (ii) any suspension of the qualification (or exemption from qualification) of any of the
Registrable Securities for sale in any jurisdiction, at the earliest practicable moment. 
 (d) Comply with all applicable rules and
regulations of the Commission. 
 (e) Furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request
(i) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (ii) such other information as may be reasonably requested in availing any Holder of any rule or
regulation of the Commission which permits the selling of any such securities without registration or pursuant to such form. 
  

 22 

 4.3 Registration Procedures; Purchaser. In connection with the Company’s registration obligations set forth
in Section 4.1 above: 
 (a) The Purchaser shall cooperate with the Company, as requested by the Company, in connection with the
preparation and filing of any Registration Statement hereunder. The Purchase shall provide the Company with a completed Selling Stockholder Questionnaire and such other information that the Company may reasonably require the Purchaser to promptly
furnish in writing to the Company as may be required in connection with such registration including, without limitation, all such information as may be requested by the Commission or FINRA or any state securities commission and all such information
regarding the Purchaser, the Registrable Securities held by the Purchaser and the intended method of disposition of the Registrable Securities. The Purchaser agrees to provide such information requested in connection with such registration within
five (5) business days after receiving such written request. The Company shall not be responsible for any delays in filing or obtaining or maintaining the effectiveness of the Registration Statement caused by any Purchaser’s failure to
timely provide a completed Selling Stockholder Questionnaire or such other information requested by the Company. 
 (b) If, in the good faith
judgment of the Company, it would be detrimental to the Company or its stockholders for the Registration Statement to be filed or for resales of Registrable Securities to be made pursuant to the Registration Statement due to (i) the existence
of a material development or potential material development involving the Company that the Company would be obligated to disclose in the Registration Statement, which disclosure would be premature or otherwise inadvisable at such time or would have
a material adverse effect on the Company or its stockholders or (ii) a proposed filing of or use of an existing registration statement in connection with a Company-initiated registration of any class of its equity securities, which, in the good
faith judgment of the Company, would adversely effect or require premature disclosure of the filing or use of such Company-initiated registration (notice thereof, a “Blackout Notice”), upon receipt of a Blackout Notice from the
Company, the Purchaser shall immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement (the period during which such disposition is discontinued, the “Blackout Period”) covering such
Registrable Securities until (i) the Company advises the Purchaser that the Blackout Period has terminated and (ii) the Purchaser receives copies of a supplemented or amended prospectus, if necessary. If so directed by the Company, the
Purchaser will deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of destruction) all copies in the Purchaser’s possession (other than a limited number of file copies) of the prospectus
covering such Registrable Securities that is current at the time of receipt of such notice. 
 (c) If the Purchaser determines to engage an
underwriter (other than the Purchaser) in connection with the offering of any Registrable Securities (an “Underwritten Offering”), the Purchaser will enter into and perform its obligations under an underwriting agreement, in usual
and customary form, including, without limitation, customary indemnification and contribution obligations, with the managing underwriter of such offering, and will take such other actions as 

  

 23 

 
are reasonably required in order to expedite or facilitate the disposition of the Registrable Securities. The Purchaser shall consult with the Company prior
to any Underwritten Offering and shall defer such Underwritten Offering for a reasonable period upon the request of the Company. 
 (d) The
Purchaser shall not take any action with respect to any distribution deemed to be made pursuant to the Registration Statement, which would constitute a violation of Regulation M under the Exchange Act or any other applicable rule, regulation or law.

 4.4 Registration Expenses. All fees and expenses of the Company incident to the performance of or compliance with Section 4.1 and
Section 4.2 hereof by the Company shall be borne by the Company. In addition, the Company shall reimburse the Holders, on a one-time basis, for the reasonable fees and expenses of counsel to the Holders of up to $10,000 in the aggregate with
respect to the review of any registration statement filed pursuant to Section 4.1 hereof, as directed by the then Holders of a majority of the Registrable Securities. 
 4.5 Indemnification. In the event that any Registrable Securities are included in a Registration Statement under this ARTICLE IV: 
 (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or
underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, or the Exchange Act, insofar as such losses,
claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”): (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, or any rule or regulation promulgated
under the Securities Act, or the Exchange Act, and the Company will pay to each such Holder, underwriter or controlling person, as incurred, any legal or other expenses reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this Section 4.5(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of
or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, underwriter or controlling person. 
 (b) To the extent permitted by law, each Holder will indemnify and hold harmless the Company, each of its directors, each of its officers, each person,
if any, who controls the Company within the meaning of the Securities Act, any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter or 

  

 24 

 
other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become subject, under the
Securities Act, or the Exchange Act, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs
in reliance upon and in conformity with written information furnished or omitted by such Holder for use in connection with such registration; and each such Holder will pay, as incurred, any legal or other expenses incurred by any person intended to
be indemnified pursuant to this Section 4.5(b), in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this Section 4.5(b) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided, further, that, in no event shall
any indemnity under this Section 4.5(b) exceed the greater of the cash value of the (i) gross proceeds from the offering received by such Holder or (ii) such Holder’s investment pursuant to this Agreement as set forth on the
signature page attached hereto. 
 (c) Promptly after receipt by an indemnified party under this Section 4.5 of notice of the
commencement of any action (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made against any indemnifying party under this Section 4.5, deliver to the indemnifying party a written notice
of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly notified, to assume the defense thereof with
counsel selected by the indemnifying party and approved by the indemnified party (whose approval shall not be unreasonably withheld); provided, however, that an indemnified party (together with all other indemnified parties which may be represented
without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party
would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 4.5, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 4.5. 
 (d) If the indemnification provided for in this Section 4.5 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense
referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage, or expense 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 in connection with the statements or omissions that resulted in such loss, liability, claim, damage,
or expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a
material fact or the alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct
or prevent such statement or omission. 
  

 25 

 (e) The obligations of the Company and Holders under this Section 4.5 shall survive the completion
of any offering of Registrable Securities in a Registration Statement under this ARTICLE IV, and otherwise. 
 4.6 Cutback. In connection with filing
the Registration Statement pursuant to Section 4.1 hereof, the obligations of the Company set forth in this ARTICLE VI are subject to any limitations on the Company’s ability to register the full complement of such shares in accordance
with Rule 415 under the Securities Act or other regulatory limitations. To the extent the number of such shares that can be registered is limited, the Company shall file a subsequent registration agreement that will provide, among other things, that
the Company will use its commercially reasonable efforts to register additional tranches of Registrable Securities as soon as permissible thereafter under applicable laws, rules and regulations so that all of such Registrable Securities are
registered as soon as reasonably practicable. 
 4.7 Sales by Purchasers. The Purchaser shall sell any and all Registrable Securities (as defined
below) purchased hereby in compliance with applicable prospectus delivery requirements, if any, or otherwise in compliance with the requirements for an exemption from registration under the Securities Act and the rules and regulations promulgated
thereunder. The Purchaser will not make any sale, transfer or other disposition of the Securities in violation of federal or state securities or “blue sky” laws and regulations. 
 4.8 Piggy-Back Registrations. If at any time during the Effectiveness Period there is not an effective Registration Statement covering all of the Registrable
Securities and the Company shall determine to prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on
Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection
with the stock option or other employee benefit plans, then the Company shall send to each Holder a written notice of such determination and, if within 15 days after the date of such notice, any such Holder shall so request in writing, the Company
shall include in such registration statement all or any part of such Registrable Securities such Holder requests to be registered, subject to customary underwriter cutbacks applicable to all holders of registration rights and any limitations imposed
by applicable law. 
 4.9 Waivers. With the written consent of the Company and the Holders holding at least a majority of the Registrable Securities
that are then outstanding, any provision of this ARTICLE IV may be waived (either generally or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely) or amended, which waiver shall
be applicable to all Holders, and shall be deemed to have been consented to by all Holders. Upon the effectuation of each such waiver or amendment, the Company shall promptly give written notice thereof to the Holders, if any, who have not
previously received notice thereof or consented thereto in writing. 
  

 26 

 ARTICLE V. 
 OTHER AGREEMENTS OF THE PARTIES 
 5.1 Transfer Restrictions. 
 (a) The Securities may only be disposed of in compliance with state and federal securities laws (including, in the case of Purchasers domiciled or formed
outside the U.S., Regulation S). In connection with any transfer of Shares, other than pursuant to an effective registration statement, Rule 144, or Regulation S, to the Company or to an Affiliate of a Purchaser or in connection with a
pledge as contemplated in Section 5.1(d), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which
opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. As a condition of transfer, any such transferee shall agree in writing
to be bound by the terms of this Agreement and shall have the rights of a Purchaser under this Agreement and the Registration Rights Agreement. 
 (b) The Purchasers that reside, are domiciled or are formed, within the U.S. agree to the imprinting, so long as is required by this Section 5.1, of a legend on any of the Shares, Warrants or Warrant Shares in the following form:

 THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE
UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR
PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO
SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN
“ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES. 
 (c) The
Purchasers that are domiciled or are formed outside of the U.S. agree to the imprinting, so long as is required by this Section 5.1, of a legend on any of the Shares and Warrant Shares in the following form: 
 THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE OR
OTHER SECURITIES LAWS, AND MAY NOT BE OFFERED, REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, 

  

 27 

 
ENCUMBERED OR OTHERWISE DISPOSED OF OR DISTRIBUTED, DIRECTLY OR INDIRECTLY, WITHIN THE UNITED STATES OR TO OR FOR THE ACCOUNT OF U.S. PERSONS UNLESS THE
TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OR PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT. THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF AGREES THAT IT WILL
NOT OFFER, REOFFER, SELL, ASSIGN, TRANSFER, PLEDGE, ENCUMBER OR OTHERWISE DISPOSE OF OR DISTRIBUTE DIRECTLY OR INDIRECTLY THESE SECURITIES IN THE UNITED STATES, ITS TERRITORIES, POSSESSIONS, OR AREAS SUBJECT TO ITS JURISDICTION, OR TO OR FOR THE
ACCOUNT OR BENEFIT OF A U.S. PERSON EXCEPT (A) TO THE COMPANY OR A SUBSIDIARY OF THE COMPANY, (B) IN CONJUNCTION WITH AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT, (C) IN COMPLIANCE WITH AN EXEMPTION
FROM REGISTRATION UNDER THE SECURITIES ACT OR (D) IN ACCORDANCE WITH THE PROVISIONS OF REGULATION S, INCLUDING RULES 904 AND 905 THEREOF. THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF FURTHER AGREES THAT ANY HEDGING TRANSACTIONS
INVOLVING THE SECURITIES WILL BE CONDUCTED IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT AND AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND; PROVIDED THAT
THE COMPANY, THE TRANSFER AGENT, AND THE REGISTRAR SHALL HAVE THE RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER, IN EACH OF THE FOREGOING CASES, TO REQUIRE DELIVERY OF A CERTIFICATION OF TRANSFER AND OPINION OF COUNSEL IN FORM SATISFACTORY TO
THEM. AS USED HEREIN, THE TERMS “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT. 
 (d) The Company acknowledges and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the Shares
to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and who agrees to be bound by the provisions of this Agreement and the provisions of ARTICLE IV hereof and, if required under
the terms of such arrangement, such Purchaser may transfer pledged or secured Shares to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of legal counsel of the pledgee,
secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or
secured party of Shares may reasonably request in connection with a pledge or transfer of the Shares, including, if the Shares are subject to registration pursuant to ARTICLE IV hereof, the preparation and filing of any required prospectus
supplement under Rule 424(b)(3) under the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders thereunder. 
  

 28 

 (e) Certificates evidencing the Securities shall not contain any legend (including the legend set forth
in Section 5.1(b)), (i) while a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities Act, or (ii) following any sale of such Securities pursuant to
Rule 144, or (iii) if, in the case of a person not an Affiliate of the Company, such Securities have been held for at least one year, or (iv) if such legend is not required under applicable requirements of the Securities Act
(including judicial interpretations and pronouncements issued by the staff of the Commission). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the Effective Date if required by the Transfer Agent to
effect the removal of the legend hereunder. The Company agrees that following the Effective Date or at such time as such legend is no longer required under this Section 5.1(e), it will, no later than three (3) Trading Days following the
delivery by a Purchaser to the Company or the Transfer Agent of a certificate representing Shares issued with a restrictive legend (such third Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to such
Purchaser a certificate representing such Shares that is free from all restrictive and other legends. Notwithstanding the foregoing, the Company shall not be required to remove any legends until all Securities represented by a single certificate are
no longer subject to restrictions. If only a portion of the Securities represented by any single certificate are subject to restrictions, the holder of the certificate may request, or the Company may require, that such certificate be cancelled and
two new certificates be issued. One certificate shall represent, and be in the amount of, Securities not subject to restrictions and shall bear no legend and the second certificate shall represent, and be in the amount of, Securities subject to
restrictions and shall bear an appropriate legend. The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section. Certificates for Shares subject
to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchasers by crediting the account of the Purchaser’s prime broker or custodian bank with the Depository Trust Company System. 
 (f) Each Purchaser, severally and not jointly with the other Purchasers, agrees that the removal of the restrictive legend from certificates representing
Shares as set forth in this Section 5.1 is predicated upon the Company’s reliance that the Purchaser will sell any Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus
delivery requirements, or an exemption therefrom, and that if Securities are sold pursuant to a Registration Statement, they will be sold in compliance with the plan of distribution set forth therein. 
 (g) Each Purchaser that is domiciled or was formed outside of the U.S. agrees on its own behalf and on behalf of any investor account for which it is
acquiring the Securities, and each subsequent permitted transferee of the Securities by its acceptance thereof will be deemed to have agreed, that all subsequent offers and sales of Securities prior to the date which is two years after the Closing
Date shall be made only (1) to the Company or a subsidiary thereof, (2) pursuant to a registration statement which has been declared effective under the Securities Act, (3) pursuant to offers and sales to non-U.S. persons that occur
outside the United States within the meaning of Regulation S and in compliance with Rules 904 and 905 thereunder, or (4) pursuant to any other available exemption from the registration requirements of the Securities Act. 

 

 29 

 (h) Each Purchaser that is domiciled or was formed outside of the U.S. represents and agrees on his, her
or its behalf and on behalf of any investor account for which it is acquiring the Shares, and each subsequent permitted transferee of the Securities, by its acceptance thereof, will be deemed to have agreed, that (i) no subscription, resale or
other transfer of the Securities has been arranged, or at Closing will have been arranged, to return the Securities to the U.S. securities markets or to a U.S. citizen or resident, and (ii) any hedging transaction involving the Securities will
be conducted only in compliance with the requirements of the Securities Act. 
 5.2 Furnishing of Information. As long as any Purchaser owns
Securities and the Company remains subject to the requirements of the Exchange Act, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the
Company after the date hereof pursuant to the Exchange Act. As long as any Purchaser owns Securities, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to the Purchasers and make publicly
available in accordance with Rule 144(c) such information as is required for the Purchasers to sell the Securities under Rule 144. The Company further covenants that it will take such further action as any holder of Securities may reasonably
request, to the extent required from time to time to enable such Person to sell such Shares without registration under the Securities Act within the requirements of the exemption provided by Rule 144. 
 5.3 Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in
Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchasers or that would be
integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval prior to the closing of such other transaction unless shareholder approval is
obtained before the closing of such subsequent transaction. 
 5.4 Securities Laws Disclosure; Publicity. The Company shall, by
8:30 a.m. (New York City time) on the Trading Day immediately following the date hereof, issue a press release or file a Form 8-K announcing the signing of this Agreement and describing the material terms of the transactions contemplated by the
Transaction Documents, including the contemplated use of proceeds. The Company and each Purchaser shall consult with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company nor any
Purchaser shall issue any such press release or otherwise make any such public statement without the prior consent of the Company, with respect to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to
any press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public
statement or communication. On or before the fourth (4th) Business Day
following execution of Transaction Documents, the Company shall file a Current Report on Form 8-K with the Commission describing the terms of the transactions contemplated hereby and including as an exhibit to such Current Report on Form 8-K the
Transaction Documents (including schedules), in the form required by the Exchange Act. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the
Commission or any regulatory agency or Trading Market, 

  

 30 

 
without the prior written consent of such Purchaser, except (i) as required by federal securities law in connection with (A) the Registration
Statement, (B) the Current Report on Form 8-K required by this Section 5.4, (C) any filing required by the Commission and (D) the filing of final Transaction Documents (including signature pages thereto) with the Commission and
(ii) to the extent such disclosure is required by law or Trading Market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure permitted under this clause (ii). 
 5.5 Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any Purchaser is an
“Acquiring Person” under any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company, or
that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the Transaction Documents or under any other agreement between the Company and the Purchasers. 
 5.6 Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company
covenants and agrees that neither it nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto such
Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that each Purchaser shall be relying on the foregoing representations in effecting transactions in
securities of the Company. 
 5.7 Use of Proceeds. The Company shall use the net proceeds from the sale of the Securities hereunder for working
capital purposes and shall not use such proceeds for the satisfaction of any portion of the Company’s debt (other than payment of trade payables in the ordinary course of the Company’s business and prior practices), or to redeem any Common
Stock or Common Stock Equivalents or to settle any outstanding litigation. 
 5.8 Reimbursement. If any Purchaser becomes involved in any capacity in
any Proceeding by or against any Person who is a stockholder of the Company (except as a result of sales, pledges, margin sales and similar transactions by such Purchaser to or with any other stockholder), solely as a result of such Purchaser’s
acquisition of the Securities under this Agreement, the Company will reimburse such Purchaser for its reasonable legal and other expenses (including the cost of any investigation preparation and travel in connection therewith) incurred in connection
therewith, as such expenses are incurred. The reimbursement obligations of the Company under this paragraph shall be in addition to any liability which the Company may otherwise have, shall extend upon the same terms and conditions to any Affiliates
of the Purchasers who are actually named in such action, proceeding or investigation, and partners, directors, agents, employees and controlling persons (if any), as the case may be, of the Purchasers and any such Affiliate, and shall be binding
upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company, the Purchasers and any such Affiliate and any such Person. The Company also agrees that neither the Purchasers nor any such Affiliates,
partners, directors, agents, employees or controlling persons shall have any liability to the Company or any Person asserting claims on behalf of or in right of the Company 

  

 31 

 
solely as a result of acquiring the Securities under this Agreement, except if such claim arises primarily from a breach of such Purchaser’s
representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser may have with any such stockholder or any violations by the Purchaser of state or federal securities laws or any conduct by
such Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance. 
 5.9 Indemnification of Purchasers. Subject to the
provisions of this Section 5.9, the Company will indemnify and hold each Purchaser and its directors, officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding
such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers,
shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a
“Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees
and costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other
Transaction Documents or (b) any action instituted against a Purchaser, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Purchaser, with respect to any of the transactions
contemplated by the Transaction Documents (unless such action is based upon a breach of such Purchaser’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser may have with
any such stockholder or any violations by the Purchaser of state or federal securities laws or any conduct by such Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any
Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own
choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense
of such Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ
counsel or (iii) in such action there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser Party, in which case the Company
shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (i) for any settlement by a Purchaser Party effected without the
Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (ii) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to (A) any Purchaser Party’s breach of
any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents, (B) any violations by the Purchaser of state or federal securities laws or (C) any
conduct by such Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance. 
  

 32 

 5.10 Reservation of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue
to reserve and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue the Shares and the Warrant Shares pursuant to this Agreement or the Warrants, as
applicable. 
 5.11 Listing of Common Stock. The Company hereby agrees to use best efforts to maintain the listing of the Common Stock on a Trading
Market (other than the OTC Bulletin Board), and as soon as reasonably practicable following the Closing (but not later than the earlier of the Effective Date and the first anniversary of the Closing Date) to take all action necessary to list all of
the Shares and Warrant Shares on such Trading Market. The Company further agrees, if the Company applies to have the Common Stock traded on any other Trading Market, it will include in such application all of the Shares and Warrant Shares, and will
take such other action as is necessary to cause all of the Shares and Warrant Shares to be listed on such other Trading Market as promptly as possible. The Company will take all action reasonably necessary to continue the listing and trading of its
Common Stock on a Trading Market and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading Market. 
 5.12 Equal Treatment of Purchasers. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same
consideration is also offered to all of the parties to the Transaction Documents. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is
intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of Shares or otherwise. 
 5.13 Short Sales and Confidentiality After The Date Hereof. Each Purchaser severally and not jointly with the other Purchasers covenants that neither it nor any
Affiliate or other Person acting on its behalf or pursuant to any understanding with it has nor will execute any Short Sales during the period commencing at the beginning of the Discussion Time and ending at the time that the transactions
contemplated by this Agreement are first publicly announced as described in Section 5.4. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are
publicly disclosed by the Company as described in Section 5.4, such Purchaser will maintain the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Each
Purchaser understands and acknowledges, severally and not jointly with any other Purchaser, that the Commission currently takes the position that coverage of short sales of shares of the Common Stock “against the box” prior to the
Effective Date of the Registration Statement with the Shares or Warrant Shares is a violation of Section 5 of the Securities Act, as set forth in Item 65, Section A, of the Manual of Publicly Available Telephone Interpretations, dated
July 1997, compiled by the Office of Chief Counsel, Division of Corporation Finance. Notwithstanding the foregoing, no Purchaser makes any representation, warranty or covenant hereby that it will not engage in Short Sales in the securities of
the Company after the time that the transactions contemplated by this Agreement are first publicly announced as described in Section 5.4. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle
whereby separate portfolio managers manage separate portions of such 

  

 33 

 
Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other
portions of such Purchaser’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Shares covered by this Agreement.

 5.14 Delivery of Shares After Closing. The Company shall deliver, or cause to be delivered, the respective Shares purchased by each Purchaser to
such Purchaser within 10 Trading Days of the Closing Date. 
 5.15 Form D; Blue Sky Filings. The Company agrees to timely file a Form D with
respect to the Securities as required under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an
exemption for, or to qualify the Securities for, sale to the Purchasers at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request of
any Purchaser. Each Purchaser shall take all commercially reasonable actions that are reasonably requested by the Company related to, or to effectuate, the filing of a Form D or any filing required pursuant to the “Blue Sky” laws of
the states of the United States which, for purposes of clarity, shall not include the payment of any fees by such Purchaser. 
 5.16 Investment
Company. The Company shall conduct its business in a manner so that it will not become subject to the Investment Company Act of 1940, as amended. 
 ARTICLE VI. 
 MISCELLANEOUS 
 6.1 Termination. This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder only and without any
effect whatsoever on the obligations between the Company and the other Purchasers, by written notice to the other parties, if the Closing has not been consummated on or before the date 14th calendar day after the date of this Agreement; provided, however, that the right to terminate this Agreement under
this Section 6.1 shall not be available to any Person whose failure to comply with its obligations under this Agreement has been the cause of or resulted in the failure of the Closing to occur on or before such time. Nothing in this
Section 6.1 shall affect the right of any party to sue for any breach by the other party (or parties). 
 6.2 Fees and Expenses. Except as
expressly set forth in the Transaction Documents to the contrary, each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation,
preparation, execution, delivery and performance of this Agreement. The Company shall pay all Transfer Agent fees, stamp taxes and other taxes and duties levied in connection with the delivery of any Securities to the Purchasers. 
 6.3 Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to
the subject matter hereof and thereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules. 
  

 34 

 6.4 Notices. Any and all notices or other communications or deliveries required or permitted to be provided

 6.5 Amendments; Waivers. No provision of this Agreement may be waived or amended except in a written instrument signed, in the case of an amendment, by the
Company and Purchasers holding at least 67% of the Shares then held by the Purchasers or, in the case of a waiver, by the party against whom enforcement of any such waived provision is sought. No waiver of any default with respect to any provision,
condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any
party to exercise any right hereunder in any manner impair the exercise of any such right. 
 6.6 Headings. The headings herein are for convenience
only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. 
 6.7 Successors and
Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent
of Purchasers holding at least 67% of the Shares then held by the Purchasers (other than by merger). Any Purchaser may assign any or all of its rights under this Agreement to any Person to whom such Purchaser assigns or transfers any Securities,
provided such transferee agrees in writing to be bound, with respect to the transferred Securities, by the provisions of the Transaction Documents that apply to the “Purchasers.” 
 6.8 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is
not for the benefit of, nor may any provision hereof be enforced by, any other Person, except (i) as otherwise set forth in Section 5.9 and (ii) the Placement Agent is an intended third party beneficiary of ARTICLE III hereof.

 6.9 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be
governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the 

  

 35 

 
interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a
party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including
with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a
copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service
of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. The parties hereby waive all rights to a trial by jury. If either party shall commence an
action or proceeding to enforce any provisions of the Transaction Documents, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred
with the investigation, preparation and prosecution of such action or proceeding. 
 6.10 Survival. The representations and warranties contained
herein shall survive the Closing and the delivery of the Shares until the second anniversary of the Closing Date. 
 6.11 Execution. This Agreement
may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being
understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding
obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. 
 6.12 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or
unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the
parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 
 6.13 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any of the other
Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction 

  

 36 

 
Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in
its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights. 
 6.14 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for
and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction. The
applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities. 
 6.15 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and
the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction
Documents and hereby agrees to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. 
 6.16 Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such
payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or
otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration
the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred. 
 6.17 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint
with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other
Transaction Document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are
in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including without
limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been, or
has had the opportunity to be, represented by its own separate legal counsel in their review and negotiation of the Transaction Documents. The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the
convenience of the Company and not because it was required or requested to do so by the Purchasers. 
  

 37 

 6.18 Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts
owing under the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to
which such partial liquidated damages or other amounts are due and payable shall have been canceled. 
 6.19 Construction. The parties agree that each
of them and/or their respective counsel has reviewed and had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall
not be employed in the interpretation of the Transaction Documents or any amendments hereto.

 Schedule 3.1(s) 
 Certain Fees 
 At Closing, the Company shall issue to the Placement Agent, or its authorized designees,
five-year warrants (the “Placement Warrants”) to purchase a number of shares of Common Stock equal to ten percent (10%) of the Shares sold pursuant to the Purchase Agreement at an exercise price equal to 110% of the Closing Price;

Agent. The Company shall also pay the Placement Agent a non-accountable expense allowance equal to $50,000 for the Placement Agent’s expenses in providing the services related to the purchase and sale of the Securities.

 Schedule 3.1(w) 
 Listing Maintenance 
 The trading price of the Company’s Common Stock has recently been below $1.00 per
share. The continued listing requirements of the Nasdaq Stock Market provide that the Company’s Common Stock may be subject to delisting if the closing bid price of the Common Stock is less than $1.00 per share for a period of 30 consecutive
trading days. Nasdaq has suspended its minimum bid price requirement until the period ending July 19, 2009, however. Although the Company has not received any notice from Nasdaq concerning its non-compliance with the minimum bid price
requirement, unless such suspension period is further extended by Nasdaq, the Company’s Common Stock may become subject to delisting if the closing bid price continues to remain below $1.00 per share for 30 consecutive trading days following
July 19, 2009. Once the suspension for the minimum price requirement expires, if the closing bid price of Common Stock remains below $1.00 for 30 consecutive trading days, the Company will likely receive a notice from Nasdaq of such
non-compliance, and be afforded a period of 180 days in which to re-establish compliance of the minimum bid price requirement. If compliance with the minimum bid price requirement is not established within such 180-day period, the Common Stock may
be delisted from the Nasdaq Capital Market. 
 In addition, Nasdaq’s continued listing requirements provide that the Company maintain either (i) a
minimum total market value of its Common Stock of at least $35 million, or (ii) a total stockholders’ equity of at least $2.5 million. As of the date of the Purchase Agreement, the total market value of the Common Stock is approximately
$20 million. As of March 31, 2009, the Company’s last reported balance sheet date, the Company had a total stockholders’ equity of approximately $3.48 million. The net proceeds from the sale of the Securities contemplated by the
Purchase Agreement, after deducting offering related expenses, will increase the Company’s total stockholders’ equity. However, unless the aggregate market value of the Company’s Common Stock increases to more than $35 million, the
Company may not comply with the minimum stockholders’ equity requirement in future periods.

 Class [A/B/C] Warrant for the Purchase 
 of Shares of Common Stock 
  

			
	 Warrant No. [    ]
	 	 Number of Shares: [        ]
 (subject to adjustment)

	 Original Issue Date: [            ], 2009
	 	

 FOR VALUE RECEIVED, NILE THERAPEUTICS, INC., a Delaware corporation (the
“Company”), hereby certifies that [            ], its designee or its permitted assigns (the “Holder”), is entitled to purchase from the Company, at any
time or from time to time commencing on             , 2009 and prior to 5:00 P.M., New York City time, on             , 2014 (the
“Exercise Period”) up to [            ] ([    ]) fully paid and non-assessable shares of common stock (subject to adjustment), $.001 par value per
share, of the Company for $[    ] per share (subject to adjustment as provided herein) and an aggregate purchase price of $[    ]. Hereinafter, (i) said common stock, $.001 par value per share, of the
Company, is referred to as the “Common Stock,” (ii) the shares of the Common Stock purchasable hereunder or under any other Warrant (as hereinafter defined) are referred to as the “Warrant Shares,”
(iii) the aggregate purchase price payable for the Warrant Shares purchasable hereunder is referred to as the “Aggregate Warrant Price,” and (iv) the price payable for each of the Warrant Shares is referred to as the
“Per Share Warrant Price.” The Aggregate Warrant Price is not subject to adjustment. 
 This Warrant is one of a series of
similar warrants issued pursuant to a Securities Purchase Agreement, dated July 7, 2009, by and among the Company and the Purchasers identified therein (the “Securities Purchase Agreement”). All such warrants, including this
Warrant and all warrants hereafter issued in exchange or substitution for this Warrant and such other similar warrants, are collectively referred to herein as the “Warrants.” The Holder, together with the holders of all other
Warrants, are collectively referred to herein as the “Holders,” and Holders of more than 50% of the outstanding Warrants are referred to as the “Majority of the Holders.” 
  

 A-1 

 1. Exercise of Warrant. 
 (a) At the Holder’s option, this Warrant may be exercised, in whole or in part, at any time or from time to time during the Exercise Period, by the
Holder upon surrender of this Warrant (with the subscription form at the end hereof duly executed) at the address set forth in Section 9(a) hereof, together with proper payment of the Aggregate Warrant Price, or the proportionate part thereof
if this Warrant is exercised in part, with payment for the Warrant Shares made by certified or official bank check payable to the order of the Company. 
 (b) If this Warrant is exercised in part, this Warrant must be exercised for a number of whole shares of Common Stock and the Holder is entitled to receive a new Warrant covering the Warrant Shares that have not been
exercised and setting forth the proportionate part of the Aggregate Warrant Price applicable to such Warrant Shares. 
 (c) Upon surrender of
this Warrant, the Company will (i) issue a certificate or certificates in the name of the Holder for the largest number of whole shares of the Common Stock to which the Holder shall be entitled and, if this Warrant is exercised in whole, in
lieu of any fractional share of the Common Stock to which the Holder shall be entitled, pay to the Holder cash in an amount equal to the fair value of such fractional share (determined in such reasonable manner as the Board of Directors of the
Company shall determine), and (ii) deliver the other securities and properties receivable upon the exercise of this Warrant, or the proportionate part thereof if this Warrant is exercised in part, pursuant to the provisions of this Warrant.

 2. Reservation of Warrant Shares. The Company will at all times reserve and keep available, solely for issuance and
delivery upon the exercise of this Warrant, such number of Warrant Shares and other securities, cash and/or property, as from time to time shall be issuable upon the exercise of this Warrant. 
 3. Protection Against Dilution. 
 (a) In case the Company shall hereafter (i) pay a dividend or make a distribution to any holder of its capital stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares,
(iii) combine its outstanding shares of Common Stock into a smaller number of shares or (iv) issue by reclassification of its Common Stock any shares of capital stock of the Company, the Per Share Warrant Price shall be adjusted to be
equal to a fraction, the numerator of which shall be the Aggregate Warrant Price and the denominator of which shall be the number of shares of Common Stock or other capital stock of the Company that the Holder would have owned immediately following
such action had such Warrant been exercised immediately prior thereto. An adjustment made pursuant to this Subsection 3(a) shall become effective immediately after the record date in the case of a dividend or distribution, and shall become effective
immediately after the effective date in the case of a subdivision, combination or reclassification. 
  

 A-2 

 (b) In case of (i) any merger or consolidation to which the Company is a party other than a merger
or consolidation in which the Company is the continuing corporation, or (ii) any sale or conveyance to another entity of the property of the Company as an entirety or substantially as a entirety, or (iii) any statutory exchange of
securities with, or tender offer by, another corporation (including any exchange effected in connection with a merger of a third corporation into the Company), or (iv) reclassification of the Common Stock or any compulsory share exchange
pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of Common Stock covered by Section 3(a) above), the Holder of
this Warrant shall have the right thereafter to receive on the exercise of this Warrant the kind and amount of securities, cash or other property which the Holder would have owned or have been entitled to receive immediately after such
reclassification, consolidation, merger, statutory exchange, tender offer, sale or conveyance had this Warrant been exercised immediately prior to the effective date of such reclassification, consolidation, merger, statutory exchange, tender offer,
sale or conveyance and in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section 3 with respect to the rights and interests thereafter of the Holder of this Warrant to
the end that the provisions set forth in this Section 3 shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the
exercise of this Warrant. The above provisions of this Section 3(b) shall similarly apply to successive reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances. The Company shall require the issuer of any shares of
stock or other securities or property thereafter deliverable on the exercise of this Warrant to be responsible for all of the agreements and obligations of the Company hereunder. Notice of any such reclassification, consolidation, merger, statutory
exchange, tender offer, sale or conveyance and of said provisions so proposed to be made, shall be mailed to the Holders of the Warrants not less than 30 days prior to such event. A sale of all or substantially all of the assets of the Company for a
consideration consisting primarily of securities shall be deemed a consolidation or merger for the foregoing purposes. 
 (c) All
calculations under this Section 3 shall be made to the nearest cent or to the nearest 1/100th of a share, as the case may be. Anything in this Section 3 to the contrary notwithstanding, the Company shall be entitled to make such reductions
in the Per Share Warrant Price, in addition to those required by this Section 3, as it in its discretion shall deem to be advisable in order that any stock dividend, subdivision of shares or distribution of rights to purchase stock or
securities convertible or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable. 
 (d) Whenever the
Per Share Warrant Price is adjusted as provided in this Section 3 and upon any modification of the rights of a Holder of Warrants in accordance with this Section 3, the Company shall promptly prepare a brief statement of the facts
requiring such adjustment or modification and the manner of computing the same and cause copies of such certificate to be mailed to the Holders of the Warrants. The Company may, but shall not be obligated to unless requested by a Majority of the
Holders, obtain, at its expense, a certificate of a firm of independent public accountants of recognized standing selected by the Board of Directors (who may be the regular auditors of the Company) setting forth the Per Share Warrant Price and the
number of Warrant Shares in effect after such adjustment or the effect of such modification, a brief statement of the facts requiring such adjustment or modification and the manner of computing the same and cause copies of such certificate to be
mailed to the Holders of the Warrants. 
  

 A-3 

 (e) If the Board of Directors of the Company shall declare any dividend or other distribution with
respect to the Common Stock other than a cash distribution out of earned surplus, the Company shall mail notice thereof to the Holders of the Warrants not less than 10 days prior to the record date fixed for determining stockholders entitled to
participate in such dividend or other distribution. 
 (f) If, as a result of an adjustment made pursuant to this Section 3, the Holder
of any Warrant thereafter surrendered for exercise shall become entitled to receive shares of two or more classes of capital stock or shares of Common Stock and other capital stock of the Company, the Board of Directors (whose determination shall be
conclusive and shall be described in a written notice to the Holder of any Warrant promptly after such adjustment) shall determine the allocation of the adjusted Per Share Warrant Price between or among shares or such classes of capital stock or
shares of Common Stock and other capital stock. 
 (g) In case any event shall occur as to which the other provisions of this Section 3
are not strictly applicable but as to which the failure to make any adjustment would not fairly protect the purchase rights represented by this Warrant in accordance with the essential intent and principles hereof then, in each such case, the Board
of Directors of the Company shall in good faith determine the adjustment, if any, on a basis consistent with the essential intent and principles established herein, necessary to preserve the purchase rights represented by the Warrants. Upon such
determination, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described therein. 
 4. Fully Paid Stock; Taxes. The shares of the Common Stock represented by each and every certificate for Warrant Shares delivered upon the exercise of this Warrant shall at the time of such delivery, be duly authorized,
validly issued and outstanding, fully paid and nonassessable, and not subject to preemptive rights or rights of first refusal, and the Company will take all such actions as may be necessary to assure that the par value, if any, per share of the
Common Stock is at all times equal to or less than the then Per Share Warrant Price. The Company shall pay all documentary, stamp or similar taxes and other similar governmental charges that may be imposed with respect to the issuance or delivery of
any Warrant Shares upon exercise of the Warrants (other than income taxes); provided, however, that if the Warrant Shares are to be delivered in a name other than the name of the Holder, no such delivery shall be made unless the person
requesting the same has paid to the Company the amount of transfer taxes or charges incident thereto, if any. 
  

 A-4 

 5. Investment Intent; Limited Transferability. 
 (a) The Holder represents that, by accepting this Warrant, it understands that this Warrant and any securities obtainable upon exercise of this Warrant
have not been registered for sale under Federal or state securities laws and are being offered and sold to the Holder pursuant to one or more exemptions from the registration requirements of such securities laws. In the absence of an effective
registration of such securities or an exemption therefrom, any certificates for such securities shall bear the legend set forth on the first page hereof. The Holder understands that it must bear the economic risk of its investment in this Warrant
and any securities obtainable upon exercise of this Warrant for an indefinite period of time, as this Warrant and such securities have not been registered under Federal or state securities laws and therefore cannot be sold unless subsequently
registered under such laws, unless an exemption from such registration is available. 
 (b) The Holder, by its acceptance of this Warrant,
represents to the Company that it is acquiring this Warrant and will acquire any securities obtainable upon exercise of this Warrant for its own account for investment and not with a view to, or for sale in connection with, any distribution thereof
in violation of the Securities Act. The Holder agrees that this Warrant and any such securities will not be sold or otherwise transferred unless (i) a registration statement with respect to such transfer is effective under the Securities Act
and any applicable state securities laws or (ii) such sale or transfer is made pursuant to one or more exemptions from the Securities Act. 
 (c) In addition to the limitations set forth in Section 1, this Warrant may not be sold, transferred, assigned or hypothecated by the Holder except in compliance with the provisions of the Securities Act and the applicable state
securities “blue sky” laws, and is so transferable only upon the books of the Company which it shall cause to be maintained for such purpose. The Company may treat the registered Holder of this Warrant as he or it appears on the
Company’s books at any time as the Holder for all purposes. The Company shall permit any Holder of a Warrant or his duly authorized attorney, upon written request during ordinary business hours, to inspect and copy or make extracts from its
books showing the registered holders of Warrants. All Warrants issued upon the transfer or assignment of this Warrant will be dated the same date as this Warrant, and all rights of the holder thereof shall be identical to those of the Holder.

 (d) The Holder 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 Warrants or the exercise of the Warrants; and (ii) the opportunity to request such additional information which the Company possesses or can acquire without
unreasonable effort or expense. 
 (e) The Holder did not (i) receive or review any advertisement, article, notice or other
communication published in a newspaper or magazine or similar media or broadcast over television or radio, whether closed circuit, or generally available; or (ii) attend any seminar, meeting or investor or other conference whose attendees were,
to such Holder’s knowledge, invited by any general solicitation or general advertising. 
  

 A-5 

 (f) The Holder is an “accredited investor” within the meaning of Regulation D under the
Securities Act. Such Holder is acquiring the Warrants for its own account and not with a present view to, or for sale in connection with, any distribution thereof in violation of the registration requirements of the Securities Act, without
prejudice, however, to such Holder’s right, subject to the provisions of the Securities Purchase Agreement, at all times to sell or otherwise dispose of all or any part of such Warrants and Warrant Shares. 
 (g) Either by reason of such Holder’s business or financial experience or the business or financial experience of its professional advisors (who are
unaffiliated with and who are not compensated by the Company or any affiliate, finder or selling agent of the Company, directly or indirectly), such Holder has the capacity to protect such Holder’s interests in connection with the transactions
contemplated by this Warrant. 
 6. Optional Redemption. 
 (a) This Warrant may be redeemed at the option of the Company, at any time after the date hereof following a period of twenty (20) consecutive
business days in which the per share volume weighted average price of the Common Stock equals or exceeds an amount that is two hundred percent (200%) of the then applicable Per Share Warrant Price, on notice as set forth in Section 6(b)
hereof, and at a redemption price equal to one-tenth of one cent ($0.001) (the “Redemption Price”) for each Warrant Share purchasable under this Warrant. 
 (b) Notice of Redemption. In the case of any redemption of this Warrant, the Company shall give notice of such redemption to the Holder hereof as provided in this Section 6(b). Notice of redemption to the
Holder of this Warrant shall be given by mailing by first-class mail, postage prepaid, to the Holder’s last address of record with the Company a notice of such redemption not less than thirty (30) days prior to the date fixed for
redemption. Any notice which is given in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives the notice. Each such notice shall specify the date fixed for redemption, the place of
redemption and the aggregate Redemption Price, and shall state that payment of the Redemption Price will be made up on surrender of this Warrant at such place of redemption, and that if not exercised by the close of business on the date fixed for
redemption, the exercise rights of the Warrant shall expire unless extended by the Company. Such notice shall also state the current Per Share Warrant Price and the date on which the right to exercise the Warrant will expire unless extended by the
Company. 
 (c) Payment of Redemption Price. If notice of redemption shall have been given as provided in Section 6(b), the
Redemption Price shall, unless the Warrant is theretofore exercised pursuant to the terms hereof, become due and payable on the date and at the place stated in such notice. On and after such date of redemption, the exercise rights of this Warrant
shall expire and this Warrant shall be null and void. On presentation and surrender of this Warrant at such place of payment in such notice specified, this Warrant shall be paid and redeemed at the Redemption Price per Warrant Share within ten
(10) days thereafter. 
 7. Loss, etc., of Warrant. Upon receipt of evidence satisfactory to the Company of the loss,
theft, destruction or mutilation of this Warrant, and of indemnity reasonably satisfactory to the Company, if lost, stolen or destroyed, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver to the
Holder a new Warrant of like date, tenor and denomination. 
  

 A-6 

 8. Warrant Holder Not Stockholder. This Warrant does not confer upon the Holder any right
to vote on or consent to or receive notice as a stockholder of the Company, as such, in respect of any matters whatsoever, nor any other rights or liabilities as a stockholder, prior to the exercise hereof; this Warrant does, however, require
certain notices to Holders as set forth herein. 
 9. Communication. No notice or other communication under this Warrant shall
be effective unless, but any notice or other communication shall be effective and shall be deemed to have been given if, the same is in writing and is mailed by first-class mail, postage prepaid, addressed to: 
 (a) the Company at Nile Therapeutics, Inc., 115 Sansome St., #310, San Francisco, CA, 94104, Attn: Daron Evans, Chief Financial Officer or such other
address as the Company has designated in writing to the Holder, or 
 (b) the Holder at
[            ], Attn: [                    ] or other such address as the Holder has
designated in writing to the Company. 
 10. Headings. The headings of this Warrant have been inserted as a matter of
convenience and shall not affect the construction hereof. 
 11. Applicable Law. This Warrant shall be governed by and
construed in accordance with the laws of the State of Delaware without giving effect to the principles of conflicts of law thereof. 
 12.
Amendment, Waiver, etc. Except as expressly provided herein, neither this Warrant nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument signed by the party against whom enforcement of
any such amendment, waiver, discharge or termination is sought; provided, however, that any provisions hereof may be amended, waived, discharged or terminated upon the written consent of the Company and the Majority of the Holders. Notwithstanding
the foregoing, (i) this Warrant may be amended and the observance of any term hereunder may be waived without the written consent of the Holder only in a manner which applies to all Warrants in the same fashion and (ii) the number of
Warrant Shares subject to this Warrant, the Per Share Purchase Price of this Warrant, and the provisions of Sections 1, 2 and 12 hereof, may not be amended, and the right to exercise this Warrant may not be waived, without the written consent of the
Holder (it being agreed that an amendment to or waiver under any of the provisions of Section 3 of this Warrant shall not be considered an amendment of the number of Warrant Shares or the Per Share Purchase Price). The Company shall give prompt
written notice to the Holder of any amendment hereof or waiver hereunder that was effected without such Holder’s written consent. No waivers of any term, condition or provision of this Warrant, in any one or more instances, shall be deemed to
be, or construed as, a further or continuing waiver of any such term, condition or provision.

 Appendix A 
 Plan of Distribution 
 We are registering the shares offered by this prospectus on behalf of the
selling stockholders. The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this
prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on
any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price,
at varying prices determined at the time of sale, or at negotiated prices. To the extent any of the selling stockholders gift, pledge or otherwise transfer the shares offered hereby, such transferees may offer and sell the shares from time to time
under this prospectus, provided that this prospectus has been amended under Rule 424(b)(3) or other applicable provision of the Securities Act to include the name of such transferee in the list of selling stockholders under this prospectus.

 The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein: 
  

	 	•	 	 ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; 

  

	 	•	 	 block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the
transaction; 

  

	 	•	 	 purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 

  

	 	•	 	 an exchange distribution in accordance with the rules of the applicable exchange; 

  

	 	•	 	 privately negotiated transactions; 

  

	 	•	 	 short sales; 

  

	 	•	 	 through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise; 

  

	 	•	 	 broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share; 

  

	 	•	 	 a combination of any such methods of sale; and 

  

	 	•	 	 any other method permitted pursuant to applicable law. 

 The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the
pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list
of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. 
  

 C-5 

 In connection with the sale of our common stock or interests therein, the selling stockholders may enter
into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our
common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other
transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares
such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). 
 The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right
to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering. Upon any exercise
of the warrants by payment of cash, however, we will receive the exercise price of the warrants. 
 The selling stockholders also may resell
all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, provided that they meet the criteria and conform to the requirements of that rule. 
 The selling shareholders might be, and any broker-dealers that act in connection with the sale of securities will be, deemed to be
“underwriters” within the meaning of Section 2(11) of the Securities Act, and any commissions received by such broker-dealers and any profit on the resale of the securities sold by them while acting as principals will be deemed to be
underwriting discounts or commissions under the Securities Act. 
 To the extent required, the shares of our common stock to be sold, the
names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an
accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus. 
 In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be
