RECITALS 
 A. On the terms
and subject to the conditions set forth herein, the Lender is willing to lend to the Company under a credit facility (the “Credit Facility”) up to an aggregate of $10,000,000, in exchange for the issuance by the Company to the
Lender of a promissory note in the aggregate principal amount of the actual amount lent from time to time, along with a related warrants to acquire shares of the Company’s capital stock 

B. Capitalized terms not otherwise defined herein shall have the meanings set forth in the form of Note (as defined below) attached hereto as
Exhibit A. 
 AGREEMENT 

NOW THEREFORE, in consideration of the foregoing, and the representations, warranties, and conditions set forth below, the parties hereto,
intending to be legally bound, hereby agree as follows: 
  

	 	1.	The Note and Warrants. 

 (a) Credit Facility. Subject
to all of the terms and conditions hereof, the Company and the Lender agree to enter into this Credit Facility, under which the Company may draw up to $10,000,000, from time to time, at any time period prior to December 31, 2016, in minimum
increments of $10,000 per draw, upon thirty (30) business days’ notice to the Lender, given in writing or by fax or by email. The amount of each draw shall be apportioned as set forth on Schedule I (the “Lender
Commitment”). 
 (b) Issuance of Notes. Draws upon the Credit Facility shall be evidenced by a subordinated promissory note
in the form of Exhibit A hereto (the “Note”), which the Company shall issue to the Lender. The principal amount outstanding from time to time under the Note shall be the total amount lent by the Lender, as
indicated on a Schedule of Amounts of Drawn attached to such Note (the “Outstanding Principal”). The obligations of the Company and the Lender under the Note are several and not joint. 

(c) Issuance of Warrants. Concurrently with the issuance of the Note to the Lender and with each draw under the Credit Facility in
accordance with Section 1(a), the Company will issue to the Lender a warrant in the form attached hereto as Exhibit B (together, the “Warrants”). Each Warrant will entitle the Lender to purchase a number of
shares of the Company’s Common Stock equal to 8% of each draw under the corresponding Credit Facility in accordance with Section 1(a) and reflected in the Schedule of Amounts Drawn attached to the Note. The exercise price of the Warrants
shall be $12.50 per share (the “Exercise Price”). The parties agree that a portion of the issue price of the investment unit consisting of the Note and the Warrant equal to the fair market value of the Warrant (which the Company and
the Lender agree is $0.01 per share) shall be allocated to the Warrant, and the balance shall be allocable to the Note. 
 (d)
Delivery. The issuance of the Note and initial Warrant shall take place at such place and time as the Company and the Lender may determine (the “Issuance Time”). At such time, the Company

 
will deliver to the Lender a Note and initial Warrant in exchange for the Lender’s commitment to funding the Credit Facility and at the time of each draw under the Credit Facility, the
Company will deliver to the Lender and additional Warrant in accordance with Section 1(c). The Note and Warrants will be registered in the Lender’s name in the Company’s records. 

(e) Use of Proceeds. Amounts draw upon the Credit Facility shall be used for general corporate purposes. 

(f) Payments. The Company will make all cash payments due under the Note in immediately available funds by 1:00 p.m. Eastern time
on the date such payment is due at the address for such purpose specified below the Lender’s name on Schedule I hereto, or at such other address, or in such other manner, as the Lender or other registered holder of a Note may
from time to time direct in writing. 
 2. Representations and Warranties of the Company. The Company represents and warrants
to the Lender that: 
 (a) Due Incorporation, Qualification, etc. The Company (i) is a corporation duly organized, validly
existing and in good standing under the laws of its state of incorporation; (ii) has the power and authority to own, lease and operate its properties and carry on its business as now conducted and as currently proposed to be conducted; and
(iii) is duly qualified, licensed to do business and in good standing as a foreign corporation in each jurisdiction where the failure to be so qualified or licensed would have a material adverse effect on the Company’s business.

“Transaction Documents”), and the consummation of the transactions contemplated thereby (i) are within the power of the Company and (ii) have been duly authorized by all necessary actions on the part of the Company. 

(c) Enforceability. This Agreement has been duly executed by the Company and constitutes a legal, valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms, except as limited by bankruptcy, insolvency or other laws of general application relating to or affecting the enforcement of creditors’ rights generally and general
principles of equity. At the time of the Note and Warrants issuance hereunder, the Note and Warrants will have been duly executed and delivered by the Company and constitute legal, valid and binding obligations of the Company, enforceable against
the Company in accordance with their terms, except as limited by bankruptcy, insolvency or other laws of general application relating to or affecting the enforcement of creditors’ rights generally and general principles of equity. 

(d) Non-Contravention. The execution and delivery by the Company of the Transaction Documents and the performance and consummation of
the transactions contemplated thereby do not and will not (i) violate the Company’s Certificate of Incorporation or Bylaws (collectively, the “Charter Documents”) or any material judgment, order, writ, decree, statute,
rule or regulation applicable to the Company; (ii) violate any provision of, or result in the breach or the acceleration of, or entitle any other Person to accelerate (whether after the giving of notice or lapse of time or both), any material
mortgage, indenture, agreement, instrument or contract to which the Company is a party or by which it is bound; or (iii) result in the creation or imposition of any lien upon any property or asset of the Company or the suspension, revocation,

without limitation, the shareholders of any Person) is required in connection with the execution and delivery of the Transaction Documents by the Company and the performance and consummation of
the transactions contemplated thereby by the Company. 
 (f) No Violation or Default. The Company is not in violation of or in
default with respect to (i) its Charter Documents or any material judgment, order, writ, decree, statute, rule or regulation applicable to the Company; or (ii) any material mortgage, indenture, agreement, instrument or contract to which
the Company is a party or by which it is bound (nor is there any waiver in effect which, if not in effect, would result in such a violation or default), where, in each case, such violation or default, individually, or together with all such
violations or defaults, could reasonably be expected to have a material adverse effect on the Company’s business. 
 (g)
Offering. Assuming the accuracy of the representations and warranties of the Lender contained in Section 3 below, the offer, issue, and sale of the Note and Warrants are, and will be, exempt from the registration and prospectus

applicable state securities laws. 
 (h) Capitalization. 

(i) As of September 30, 2014 (the “Capitalization Date”), the authorized capital stock of the Company consisted of
20,000,000 shares of Common Stock, of which 10,000,000 shares were issued and outstanding. 
 (ii) The Company had reserved an aggregate of
2,000,000 shares of Common Stock for issuance to employees, consultants, other advisors and directors pursuant to its 2014 Stock Plan, under which options to purchase 1,382,750 shares were issued and outstanding as of the Capitalization Date. 

(i) Financial Statements. The Company has made available to the Lender, upon request, its unaudited financial statements for the fiscal
year ended December 31, 2013 and its unaudited financial statements for the six-month period ended June 30, 2014 (collectively, the “Financial Statements”). The Financial Statements have been prepared in accordance with
generally accepted accounting principles applied on a consistent basis throughout the periods indicated, except that the unaudited Financial Statements may not contain all footnotes required by generally accepted accounting principles. The Financial
Statements are complete and correct in all material respects and fairly present the financial condition and operating results of the Company as of the dates, and for the periods, indicated therein, subject to normal year-end audit adjustments.
Except as set forth in the Financial Statements, the Company has no material liabilities or obligations, contingent or otherwise, other than (i) liabilities incurred in the ordinary course of business subsequent to June 30, 2014 and
(ii) obligations under contracts and commitments incurred in the ordinary course of business and not required under generally accepted accounting principles to be reflected in the Financial Statements, which, in both cases, individually or in
the aggregate are not material to the financial condition or operating results of the Company. Except as disclosed in the Financial Statements, the Company is not a guarantor or indemnitor of any indebtedness of any other person, firm or
corporation. 
 (j) Title to Properties and Assets. The Company owns its property and assets free and clear of all mortgages, liens,
loans and encumbrances. With respect to the property and assets it leases, the Company is in compliance with such leases and, to the best of its knowledge, holds a valid leasehold interest free of any liens, claims or encumbrances. 

(k) Litigation. There is no action, suit, proceeding or investigation pending, or currently threatened, against the Company, including
without limitation, any action that questions the validity of the 

  
 3 

 
Transaction Documents, or the right of the Company to enter into such agreements, or to consummate the transactions contemplated hereby and thereby, or which, either in any case or in the
aggregate, might have a material adverse effect, which might result in any material impairment of the right or ability of the Company to carry on its business as now conducted or as proposed to be conducted, or which might result in any change in
the current equity ownership of the Company. The Company is not a party or subject to the provisions of any order, writ, injunction, judgment or decree of any court or government agency or instrumentality. There is no action, suit, proceeding or
investigation by the Company currently pending or that the Company intends to initiate. 
 (l) Disclosure. Neither this Agreement nor
any other agreement (including the other Transaction Documents), document, certificate or written statement furnished to the Lender or its counsel by or on behalf of the Company in connection with the transactions contemplated hereby or thereby
contains any untrue statement of a material fact or omits to state a material fact relating directly to the Company or its subsidiaries necessary in order to make the statements contained herein or therein not misleading. There is no fact within the
knowledge of the Company which has not been disclosed herein or in writing to the Lender and which taken by itself would constitute a circumstance having, or could reasonably be expected to have, a material adverse effect. 

3. Representations and Warranties of Lender. The Lender represents and warrants to the Company as of the Effective Date as
follows: 
 (a) Binding Obligation. The Lender has full legal capacity, power and authority to execute and deliver this Agreement and
to perform its obligations hereunder. Each of this Agreement and the Note and Warrants issued to the Lender is a valid and binding obligation of the Lender, enforceable against the Lender in accordance with its terms, except as limited by
bankruptcy, insolvency or other laws of general application relating to or affecting the enforcement of creditors’ rights generally and general principles of equity. 

(b) Securities Law Compliance. The Lender has been advised that the sale and issuance of the Note and Warrants has not been registered
under the Securities Act, or any state securities laws and, therefore, the Note and Warrants cannot be resold unless they are registered under the Securities Act and applicable state securities laws or unless an exemption from such registration
requirements is available. The Lender is aware that the Company is under no obligation to effect any such registration with respect to the Note or Warrants or to file for or comply with any exemption from registration in connection with any resale
of the Note or Warrants. The Lender has not been formed solely for the purpose of making this investment and is purchasing the Note and Warrants to be acquired by the Lender hereunder for its own account for investment, not as a nominee or agent,
and not with a view to, or for resale in connection with, the distribution thereof. The Lender has such knowledge and experience in financial and business matters that the Lender is capable of evaluating the merits and risks of such investment, is
able to incur a complete loss of such investment and is able to bear the economic risk of such investment for an indefinite period of time. The Lender is an accredited Lender as such term is defined in Rule 501 of Regulation D under the
Securities Act. 
 (c) Access to Information. The Lender acknowledges that, to the Lender’s knowledge, the Company has given the
Lender access to the corporate records and accounts of the Company and to all information in the Company’s possession relating to the Company, has made its officers and representatives available for interview by the Lender, and has furnished
the Lender with all documents and other information requested by the Lender for the Lender to make an informed decision with respect to the purchase of the Note and Warrants. 

(d) Investment Experience. The Lender is a Lender in securities of companies in the development stage and acknowledges that it is able
to fend for itself, can bear the economic risk of its 

  
 4 

 
investment and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Note. If other than an individual,
the Lender also represents it has not been organized solely for the purpose of acquiring the Note. 
 (e) Exculpation. The Lender
acknowledges that it is not relying upon any Person, other than the Company and its officers and directors, in making its investment or decision to invest in the Company. The Lender agrees that neither the Lender nor the respective controlling
Persons, officers, directors, partners, agents, or employees of the Lender shall be liable to any other Lender for any action heretofore taken or omitted to be taken by any of them in connection with the purchase of the securities contemplated
hereby. 
 4. Covenants; Miscellaneous. 

(a) Waivers and Amendments. Any provision of this Agreement may be amended, waived or modified only upon the written consent of the
Company and the Lender. 
 (b) Governing Law. This Agreement will be governed by and construed in accordance with the laws of the
State of Delaware as such laws apply to contracts entered into and wholly to be performed therein by residents of such state. 
 (c)
Survival. The representations, warranties, covenants and agreements made herein shall survive the execution and delivery of this Agreement, provided, however, that the covenants and agreements set forth in Section 4(e) shall
terminate in all respects upon the repayment in full of the Note and exercise of the Warrants issued hereunder. 
 (d) Successors and
Assigns. The rights and obligations of the Company and the Lender shall be binding upon and benefit the successors, assigns, heirs, administrators and transferees of the parties. 

(e) Replacement of the Notes and Warrants. The Company will keep, at its principal executive office, books for the registration of the
Note and Warrants. Upon receipt by the Company of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of the Note or Warrants and (i) in the case of loss, theft or destruction, of indemnity
reasonably satisfactory to it; or (ii) in the case of mutilation, upon surrender thereof, the Company, at its expense, will execute and deliver in lieu thereof a new Note or Warrants executed in the same manner as the Note or Warrants being
replaced, and, in the case of the Note, in the same principal amount as the unpaid principal amount of the Note and dated the date to which interest shall have been paid on the Note or, if no interest shall have yet been so paid, dated the date of
the Note 
 (f) Tax Withholding. Notwithstanding any other provision of this Agreement, the Company shall be entitled to deduct and
withhold from any amounts payable or otherwise deliverable pursuant to this Agreement such amounts as may be required to be deducted or withheld therefrom under any provision of applicable law, and to request and be provided any necessary tax forms
and information, including Internal Revenue Service Form W-9, Form W-8BEN, or Form W-8BEN-E as applicable, from each beneficial owner of the Notes. To the extent such amounts are so deducted or withheld and paid over to the appropriate taxing
authority, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts otherwise would have been paid. 

(g) Entire Agreement. This Agreement together with the Note and Warrants constitutes and contain the entire agreement among the Company
and the Lender and supersedes any and all prior agreements, negotiations, correspondence, understandings and communications among the parties, whether written or oral, respecting the subject matter hereof.

NOTE CONVERSION AGREEMENT 

This NOTE CONVERSION AGREEMENT (the “Agreement”) is made as of December 4, 2014, by and between MultiVir, Inc., a
Delaware corporation (the “Company”), and Pope Investments II, LLC (the “Investor”). 
 WHEREAS, the
Investor was issued from the Company the promissory notes set forth in Schedule 1 hereto (the “Notes”); 
 WHEREAS,
the Company and the Investor now desire to convert all of the outstanding principal of the Notes into shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”) at the conversion prices set forth on
Schedule 1 hereto; and 
 WHEREAS, the Company and the Investor have agreed to cancel and extinguish any and all accrued and unpaid
interest on the Notes. 
 NOW, THEREFORE, in exchange for the mutual promises contained herein, and other good and valuable consideration,
the receipt and sufficiency of which is hereby acknowledged, the parties hereby agree as follows: 
 ARTICLE 1 

Conversion of Notes 
 1.1
Conversion of Notes. Subject to the terms and conditions of this Agreement, Investor hereby agrees to convert the outstanding aggregate principal amount, together with all accrued and unpaid interest through October 15, 2014, under
the Notes into, and the Company agrees to sell and issue to the Investor, an aggregate of 5,285,596 shares of Common Stock (the “Shares”) at the conversion prices set forth on Schedule 1 hereto. Upon such conversion, the
Company shall be forever released from all its obligations and liabilities under the Notes, including any and all accrued and unpaid interest on the Notes subsequent to October 15, 2014. This Agreement constitutes an amendment to the
outstanding Notes and shall supersede all terms of the Notes that are inconsistent with the terms of this Agreement. Investor shall deliver the original Notes (or a notice to the effect that the original Notes have been lost, stolen or destroyed and
an agreement acceptable to the Company whereby the Investor agrees to indemnify the Company from any loss incurred by it in connection with such Notes); provided, however, that upon the execution of this Agreement, the Notes shall be deemed
converted and of no further force and effect, whether or not such Notes are delivered for cancellation as set forth above. 
 1.2 Waiver
of Notice. The Investor hereby waives any required notice to be provided by the Company under the Notes in connection with the consummation of the transactions contemplated under this Agreement. 

ARTICLE 2 

Representations, Warranties and Covenants of the Investor 

Investor hereby represents, warrants and covenants to the Company with respect to the purchase of the Shares as follows: 

2.1 Binding Obligation; Authority. Investor has full legal capacity, power and authority to execute and deliver this Agreement and
to perform its obligations hereunder. This Agreement, when 

  

 
executed and delivered by the Investor, will constitute valid and legally binding obligations of the Investor, enforceable against the Investor in accordance with its terms, except as limited by
bankruptcy, insolvency or other laws of general application relating to or affecting the enforcement of creditors’ rights generally and general principles of equity. 

2.2 Investment Intent. Investor is purchasing the Shares for investment for the Investor’s own account only and not with a view
to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). Investor understands that the Shares have not been registered under the
Securities Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Investor’s investment intent as expressed herein. In this regard, Investor understands that, in view of the
Securities and Exchange Commission (“Commission”), the statutory basis for such exemption may not be present if the Investor’s representations meant that the Investor’s present intention was to hold these securities for a
minimum capital gains period under the tax statutes, for a deferred sale, for a market rise, for a sale if the market does not rise, or for a year or any other fixed period in the future. 

2.3 Restricted Securities. Investor further acknowledges and understands that the Shares must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such registration is available. Investor further acknowledges and understands that the Company is under no obligation to register the Shares. Investor understands that the
certificate evidencing the securities will be imprinted with a legend which prohibits the transfer of the securities unless they are registered or such registration is not required in the opinion of counsel for the Company. Investor is aware of the
adoption of Rule 144 by the Commission, promulgated under the Securities Act, which permits limited public resale of securities acquired in a non-public offering subject to the satisfaction of certain conditions. 

2.4 Accredited Investor; Experience. Investor is an “accredited investor” as that term is defined in Rule 501 under
the Securities Act. Investor has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to the Company so that it is capable of evaluating the merits and risks of its investment in the
Company and has the capacity to protect its own interests. Investor is capable of bearing a complete loss of its investment in the Company. 

2.5 Access to Information. Investor acknowledges that the Company has given the Investor access to the corporate records and
accounts of the Company and to all information in its possession relating to the Company, has made its officers and representatives available for interview by the Investor, and has furnished the Investor with all documents and other information
required for the Investor to make an informed decision with respect to the purchase of the Shares. 
 2.6 Tax
Liability. Investor has reviewed with its own tax advisors the federal, state and local tax consequences of this investment and the transactions contemplated by this Agreement. Investor has relied solely on such advisors and not on any
statements or representations of the Company or any of its agents. Investor understands that it (and not the Company) shall be responsible for its own tax liability that may arise as a result of this investment or the transactions contemplated by
this Agreement. Investor acknowledges that the Company has no obligation in regard to the future conduct of its business, to act or refrain from acting in any manner, regardless of the loss of any tax benefit to the Investor in connection with the
purchase, ownership, or sale of the Shares, which may result from such action or inaction. 
 2.7 Investor Counsel. Investor
acknowledges that it has had the opportunity to review this Agreement, the exhibits and schedules attached hereto and the transactions contemplated hereby with its own legal counsel. Investor is relying solely on such counsel and not on any
statements or representations of the Company or its agents for legal advice with respect to this investment or the transactions contemplated hereby.

 2.8 Legends 

(a) Securities Legend. It is understood that each certificate representing the Shares and any securities issued in respect thereof or
exchange therefor shall bear the legend below in substantially the following form (in addition to any legend required under applicable state securities laws): 

“THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED
OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED OR UNLESS SOLD PURSUANT TO RULE 144 (OR
SUCH SIMILAR RULE) OF SUCH ACT.” 
 (b) Market Stand-off Legend. It is understood each certificate representing the Shares and
any securities issued in respect thereof or exchange therefor shall bear the legend below in substantially the following form:

SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN THE NOTE CONVERSION AGREEMENT PURSUANT TO WHICH THESE SHARES WERE
ISSUED, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY.” 
 2.9 Market Stand-off
Agreement. Investor hereby agrees that such Investor shall not sell or otherwise transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a
sale, of any common stock (or other securities) of the Company held by the Investor (other than those included in the registration) during the one hundred eighty (180) day period following the effective date of a registration statement of the
Company filed under the Securities Act (or such other period as may be requested by the Company or an underwriter to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst
recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto), provided that: (i) such agreement shall apply
only to the Company’s firm commitment underwritten initial public offering pursuant to an effective registration statement filed under the Securities Act covering the offering and sale of the Company’s common stock and (ii) all
officers and directors of the Company and holders of at least one percent (1%) of the Company’s voting securities are bound by and have entered into similar agreements. The obligations described in this section shall not apply to a
registration relating solely to employee benefit plans on Form S-l or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the
future. The Company may impose stop-transfer instructions and may stamp each such certificate with the legend set forth in Section 2.8(b) with respect to the shares of common stock (or other securities) subject to the foregoing restriction
until the end of such one hundred eighty (180) day (or other) period.
