of the capital stock of the Purchaser, (C) a limited liability company transferring to its members or former members in accordance with their interest in the limited liability company, or (D) an individual transferring to the
Purchaser’s spouse, children or grandchildren or a trust for the exclusive benefit of an individual Purchaser; provided that in each case the transferee will agree in writing to be subject to the terms of this Agreement and the
Registration Rights Agreement. 
 (b) Legends. Certificates evidencing the Securities shall bear any legend as required
by the “blue sky” laws of any state and a restrictive legend in substantially the following form, until such time as they are not required under Section 4.1(c): 
 [THE SHARES REPRESENTED HEREBY HAVE NOT BEEN] / [NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES HAVE BEEN] REGISTERED UNDER THE UNITED STATES SECURITIES ACT
OF 1933, AS AMENDED, OR UNDER THE SECURITIES LAW OF ANY FOREIGN JURISDICTION OR ANY STATE WITHIN THE UNITED STATES. SUCH [SHARES] / [SECURITIES] MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, OR HYPOTHECATED ABSENT AN EFFECTIVE REGISTRATION
THEREOF UNDER SUCH ACT OR COMPLIANCE WITH RULE 144 PROMULGATED 

  
 23 









 
UNDER SUCH ACT, OR SUCH FOREIGN OR STATE SECURITIES LAW OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT
REQUIRED. 
 (c) Removal of Legends. The legend set forth in Section 4.1(b) shall be removed and the Company shall
issue a certificate without such legend or any other “restrictive” legend to the holder of the applicable Securities upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at the
Depository Trust Company (“DTC”), if (i) such Securities are registered for resale under the Securities Act pursuant to an effective registration statement, (ii) such Securities are sold or transferred pursuant to Rule 144
(assuming the transferor is not an Affiliate of the Company), or (iii) such Securities are eligible for sale under Rule 144 without any limits or restrictions provided in Rule 144. The Company shall cause Company Counsel to issue the legal
opinion referred to in the Irrevocable Transfer Agent Instructions to the Company’s transfer agent on the Effective Date. Any fees (with respect to the Transfer Agent, Company Counsel or otherwise) associated with the issuance of such opinion
or the removal of such legend shall be borne by the Company. If any portion of the Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, or if such Warrant Shares may be sold
under Rule 144 without any limits or restrictions provided in Rule 144, then such Warrant Shares shall be issued free of all legends. Following the Effective Date, or at such earlier time as a legend is no longer required for certain Securities, the
Company will no later than three Trading Days following the delivery by a Purchaser to the Company or the Transfer Agent (with notice to the Company) of (i) a legended certificate representing such Shares or Warrant Shares (endorsed or with
stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer) or (ii) an Exercise Notice in the manner stated in the Warrants to effect the exercise of such Warrant in accordance with
its terms and an opinion of counsel to the extent required by Section 4.1(a) (such third Trading Day, the “Legend Removal Date”), to deliver or cause to be delivered to such Purchaser a certificate representing such Securities that is
free from all restrictive and other legends. 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 4.1(c). Certificates for Shares or
Warrant 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 with DTC. 

(d) Acknowledgement. Each Purchaser hereunder acknowledges (i) that the Company’s agreement hereunder to remove any
legends from the Shares or the Warrant Shares is not an affirmative statement or representation that such Shares or the Warrant Shares are freely tradable and (ii) its primary responsibilities under the Securities Act and accordingly will not
sell the Shares, the Warrant Shares or any interest therein without complying with the requirements of the Securities Act. While the above-referenced registration statement remains effective, each Purchaser hereunder may sell the shares in
accordance with the plan of distribution contained in the registration statement and if it does so it will comply therewith and with the related prospectus delivery requirements unless an exemption therefrom is available. Each Purchaser, severally
and not jointly with the other Purchasers, agrees that if it is notified by the Company in writing at any time after the date any legend is removed pursuant to Section 4.1(c) that the registration statement registering the resale of the Shares
or the Warrant Shares is not effective or 

  
 24 









 
that the prospectus included in such registration statement no longer complies with the requirements of Section 10 of the Securities Act, the Purchaser will refrain from selling such Shares
and Warrant Shares until such time as the Purchaser is notified by the Company that such registration statement is effective or such prospectus is compliant with Section 10 of the Exchange Act, unless such Purchaser is able to, and does, sell
such Shares or Warrant Shares pursuant to an available exemption from the registration requirements of Section 5 of the Securities Act. 
 (e) Buy-In. If the Company shall fail for any reason or for no reason to issue to a Purchaser unlegended certificates within three Trading Days of receipt of documents necessary for the removal of
the legend set forth above (the “Deadline Date”), then, in addition to all other remedies available to such Purchaser, if on or after the Trading Day immediately following such three Trading Day period, such Purchaser purchases (in an open
market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the holder of shares of Common Stock that such Purchaser anticipated receiving from the Company without any restrictive legend (a “Buy-In”),
then the Company shall, within three Trading Days after such Purchaser’s request and in such Purchaser’s sole discretion, either (i) pay cash to the Purchaser in an amount equal to such Purchaser’s total purchase price (including
brokerage commissions, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such shares of Common Stock) shall terminate, or
(ii) promptly honor its obligation to deliver to such Purchaser a certificate or certificates representing such shares of Common Stock and pay cash to the Purchaser in an amount equal to the excess (if any) of the Buy-In Price over the product
of (A) such number of shares of Common Stock, times (B) the Closing Sales Price on the Deadline Date. 
 4.2
Acknowledgment of Dilution. The Company acknowledges that the issuance of the Securities may result in dilution of the outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Company further
acknowledges that its obligations under the Transaction Documents, including without limitation its obligation to issue the Shares and the Warrant Shares pursuant to the Transaction Documents, are unconditional and absolute and not subject to any
right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim the Company may have against any Purchaser and regardless of the dilutive effect that such issuance may have on the ownership of the other
stockholders of the Company. 
 4.3 Reservation of Common Stock. The Company shall take all action necessary to at all
times have authorized, and reserved for the purpose of issuance from and after the Closing Date, no less than 100% of the maximum number of shares of Common Stock issuable upon exercise of the Warrants issued at the Closing (without taking into
account any limitations on exercise of the Warrants set forth in the Warrants). 
 4.4 Furnishing of Information. In
order to enable the Purchasers to sell the Securities under Rule 144 of the Securities Act, until such time as each Purchaser can sell under Rule 144 (A) without limitations as to volume of sales, method of sale requirements or notice
requirements and (B) without the requirement for the Company to be in compliance with the current public information requirement under Rule 144(c)(1), the Company shall use its commercially reasonable efforts to timely file (or obtain
extensions in respect thereof and file 

  
 25 









 
within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act. During such period, if the Company is not required to file
reports pursuant to such laws, 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 Shares and Warrant Shares under Rule 144. The
Company further covenants that it will take such further action as any holder of Securities may reasonably request, all to the extent required from time to time to enable such Person to sell the Shares and Warrant Shares without registration under
the Securities Act within the limitation of the exemptions provided by Rule 144. 
 4.5 Reporting Status. Other than in
connection with a Fundamental Transaction (as such term is defined in the Warrants), during the one-year period from and after the Effective Date, the Company shall not terminate its status as an issuer required to file reports under the Exchange
Act even if the Exchange Act or the rules and regulations thereunder would otherwise permit such termination. 
 4.6 Form D
and Blue Sky. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D. The Company shall take such action and make all filings and reports relating to the offer and sale of the Securities 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 pursuant to this Agreement under applicable securities or “Blue Sky” laws of the
states of the United States (or to obtain an exemption from such qualification). 
 4.7 No Integration. The Company shall
not, and shall use its best efforts to ensure that no Affiliate of the Company shall, 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 will 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 will 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 stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction.

 4.8 Securities Laws Disclosure; Publicity. By 9:00 a.m., New York City time, on the Trading Day immediately following
the execution of this Agreement, the Company shall issue a press release (the “Press Release”) reasonably acceptable to the Purchasers and the Placement Agent. On or before 9:00 a.m., New York City time, on the second Trading Day following
the execution of this Agreement (or such earlier time as required by law), the Company will file a Current Report on Form 8-K with the Commission describing the terms of the Transaction Documents (and including as exhibits to such Current Report on
Form 8-K the material Transaction Documents (including, without limitation, this Agreement, the form of Warrant and the Registration Rights Agreement)). Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser
or an Affiliate of any Purchaser, or include the name of any Purchaser or an Affiliate of any Purchaser in any press release or filing with the Commission (other than the Registration Statement or the Form 8-K) or any regulatory agency or Trading
Market, without the prior written consent of such Purchaser, except (i) as required by 

  
 26 









 
federal securities law in connection with (A) any registration statement contemplated by the Registration Rights Agreement and (B) the filing of final Transaction Documents (including
signature pages thereto) with the Commission and (ii) to the extent such disclosure is required by law, request of the Staff of the Commission or Trading Market regulations, in which case the Company shall provide the Purchasers with prior
written notice of such disclosure permitted under this subclause (ii). 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 this Section 4.8, 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). 

4.9 Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated by the
Transaction Documents, the Company shall not, and shall cause each Subsidiary and each of their respective officers, directors, employees and agents, not to, provide any Purchaser with any material, non-public information regarding the Company or
any of its Subsidiaries from and after the filing of the Press Release without the express written consent of such Purchaser, unless prior thereto such Purchaser shall have executed a written agreement regarding the confidentiality and use of such
information. 
  

	 	4.10	Indemnification. 

 (a)
Indemnification of Purchasers. In addition to the indemnity provided in the Registration Rights Agreement, the Company will indemnify and hold each Purchaser and its directors, officers, stockholders, 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, stockholders, 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 person (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 (collectively, “Losses”) that any such Purchaser Party may suffer or incur as a result of or relating to 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, as to any claims brought by any third party against such Purchaser, for any other cause of action arising from the execution and
delivery hereof or thereof by the Company. The Company will not be liable to any Purchaser Party under this Agreement to the extent, but only to the extent that the Loss is attributable to 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) Conduct of Indemnification Proceedings. Promptly after receipt by any Person (the “Indemnified Person”) of notice of any demand, claim or circumstances which would or might give rise
to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity may be sought pursuant to Section 4.10(a), such Indemnified Person shall promptly notify the Company in writing and the Company shall assume
the defense thereof, 

  
 27 









 
including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all fees and expenses; provided, however, that the failure of any
Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company is actually and materially prejudiced by such failure to notify. In any such proceeding, any Indemnified
Person shall have the right to retain its own counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless: (i) the Company and the Indemnified
Person shall have mutually agreed to the retention of such counsel; (ii) the Company shall have failed promptly to assume the defense of such proceeding and to employ counsel reasonably satisfactory to such Indemnified Person in such
proceeding; or (iii) in the reasonable judgment of counsel to such Indemnified Person, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Company shall not
be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. Without the prior written consent of the Indemnified Person, which consent shall not be
unreasonably withheld, delayed or conditioned, the Company shall not affect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought
hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding. 
 4.11 Use of Proceeds. The Company intends to use the net proceeds from the sale of the Securities hereunder for working capital and general corporate purposes, including to fund its Phase 3
clinical trial for its current product candidate. 
 4.12 Short Sales After The Date Hereof. Each Purchaser shall refrain
from, and shall cause its Trading Affiliates to refrain from, engaging, directly or indirectly, in any Short Sales involving the Company’s securities during the period from the date hereof until the earliest to occur of (i) the Effective
Date or (ii) the Effectiveness Deadline. 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 apply only with respect to the portion of assets
managed by the portfolio manager that have knowledge about the financing transaction contemplated by this Agreement. Each Purchaser understands and acknowledges, severally and not jointly with any other Purchaser, that the Commission currently takes
the position that covering a short position established prior to effectiveness of a resale registration statement with shares included in such registration statement would be a violation of Section 5 of the Securities Act, as set forth in
Item 65, Section 5 under Section A, of the Manual of Publicly Available Telephone Interpretations, dated July 1997, compiled by the Office of Chief Counsel, Division of Corporation Finance. 

4.13 Listing of Securities. The Company shall use its reasonable best efforts to cause the Common Stock to be quoted on an OTC
Quotation System as soon as practicable after the Initial Registration Statement required to be filed by the Company with respect to the Shares and the Warrant Shares is declared effective by the Commission and, if otherwise eligible pursuant to
applicable listing requirements, to be listed on the Nasdaq as soon as practicable following the acceptance of the Common Stock for quotation on an OTC Quotation System. 

  
 28

initially be vacant until filled in accordance with this Section 4.14(a)(iii). 
 (iv) The Valence Director, the
Purchaser-Designated Independent Director and the Board-Designated Independent Director are together referred to herein as the “Purchaser Directors.” 
 None of the parties hereto and no officer, director, stockholder, partner, employee or agent of any party makes any representation or warranty as to the fitness or competence of the nominee of any party
hereunder to serve on the Board of Directors by virtue of such party’s execution of this Agreement or by the act of such party in voting for such nominee pursuant to this Agreement. 

(b) Nomination of Purchaser Directors. On all matters relating to the election of directors of the Company, the Company shall use
its reasonable best efforts to nominate the Purchaser Directors for election to the Board of Directors as part of the slate of nominees recommended by the Board of Directors. 

  
 29 









 (d) Removal; Filling Vacancies. Upon the request of any Person (or group of Persons)
entitled to designate a Purchaser Director as provided in Section 4.14(a), each Purchaser and Prior Investor agrees to vote its shares of the Company’s capital stock registered in their respective names or beneficially owned by them as of
the date hereof and any and all other securities of the Company legally or beneficially acquired after the date hereof for the removal of such director. Any vacancy in the directorship of a Purchaser Director shall be filled as provided in
Section 4.14(a). 
 (e) Classification of Board. If at any time after the date hereof, the Board of Directors is
structured such that a portion of the directors serve for different term lengths (i.e., becomes “classified”), the Company and the Purchasers agree to use good faith efforts to discuss and mutually agree as to the term length that
shall be applicable to each Purchaser Director. 
 (f) Committees. At any time when a Person is entitled to designate a
Purchaser Director, such Purchaser Director shall be entitled to sit on each committee of the Board of Directors (subject to such Purchaser Director satisfying the requirements applicable to directors of companies listed on Nasdaq, as applicable,
and other applicable qualifications under law). 
 (g) Termination. This Section 4.14 shall automatically terminate
and be of no further force or effect upon the later to occur of: (i) as to each Purchaser Director, at the end of such Purchaser Director’s initial term of office; or (ii) as to all Purchaser Directors, the date that the Common Stock
is listed on a Trading Market. 
 (h) Further Assurances. The Company, each Purchaser and each Prior Investor shall take
all such action as shall be reasonably necessary to implement the rights and obligations of the parties set forth in this Section 4.14.

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 Proceeding, any claim that it is not personally subject to the
jurisdiction of any such New York Court, or that such Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such
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 manner permitted by law. 
 6.9 Survival. Subject to the survival period of Section 4.14 as governed by Section 4.14(f), and subject to applicable statute of limitations, the representations, warranties, agreements
and covenants contained herein shall survive the Closing and the delivery of the Securities. 
 6.10 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 signature page were an original thereof. 

  
 34 









 6.11 Severability. If any provision of this Agreement is held to be invalid or
unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision
that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement. 

6.12 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, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably
satisfactory to the Company and the Transfer Agent of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless the Company and the
Transfer Agent for any losses in connection therewith or, if required by the Company or the Transfer Agent, a bond in such form and amount as is reasonably required by the Company or the Transfer Agent. The applicants for a new certificate or
instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities. If a replacement certificate or instrument evidencing any Securities is requested due to a mutilation
thereof, the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement. 
 6.13 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 described in the foregoing sentence and hereby agree to waive
in any action for specific performance of any such obligation (other than in connection with any action for a temporary restraining order) the defense that a remedy at law would be adequate. 

6.14 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. 
 6.15 Adjustments in Share Numbers and Prices. In the event of any stock split,
subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar
recapitalization or event occurring after the date hereof, each reference in any Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such event. 

  
 35 









 6.16 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 of the obligations of any other Purchaser under any
Transaction Document. The decision of each Purchaser to purchase Securities pursuant to the Transaction Documents has been made by such Purchaser independently of any other Purchaser and independently of any information, materials, statements or
opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or any Subsidiary which may have been made or given by any other Purchaser or by
any agent or employee of any other Purchaser, and no Purchaser and any of its agents or employees shall have any liability to any other Purchaser (or any other Person) relating to or arising from any such information, materials, statement or
opinions. Nothing contained herein or in any 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 acknowledges that no other Purchaser has acted as
agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Securities or enforcing its rights under 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. The Company acknowledges that each of the Purchasers has been provided with the same Transaction Documents for the purpose of closing a transaction with multiple
Purchasers and not because it was required or requested to do so by any Purchaser. The Company’s obligations to each Purchaser under this Agreement are identical to its obligations to each other Purchaser other than such differences resulting
solely from the number of Securities purchased by such Purchaser, but regardless of whether such obligations are memorialized herein or in another agreement between the Company and a Purchaser.

 This Investor Questionnaire (“Questionnaire”) must be completed by each potential investor in connection with the offer and sale of the shares of the common stock, par value $0.001 per
share, and shares of common stock that may be issued upon exercise of certain warrants (collectively, the “Securities”), of Celator Pharmaceuticals, Inc., a Delaware corporation (the “Corporation”). The Securities
are being offered and sold by the Corporation without registration under the Securities Act of 1933, as amended (the “Act”), and the securities laws of certain states, in reliance on the exemptions contained in Section 4(2) of
the Act and on Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws. The Corporation must determine that a potential investor meets certain suitability requirements before offering or selling
Securities to such investor. The purpose of this Questionnaire is to assure the Corporation that each investor will meet the applicable suitability requirements. The information supplied by you will be used in determining whether you meet such
criteria, and reliance upon the private offering exemptions from registration is based in part on the information herein supplied. 
 This
Questionnaire does not constitute an offer to sell or a solicitation of an offer to buy any security. Your answers will be kept strictly confidential. However, by signing this Questionnaire, you will be authorizing the Corporation to provide a
completed copy of this Questionnaire to such parties as the Corporation deems appropriate in order to ensure that the offer and sale of the Securities will not result in a violation of the Act or the securities laws of any state and that you
otherwise satisfy the suitability standards applicable to purchasers of the Securities. All potential investors must answer all applicable questions and complete, date and sign this Questionnaire. Please print or type your responses and attach
