	Re:	Subscription
    to Purchase Units of Mateon Therapeutics, Inc.


 


Ladies
and Gentlemen:


 


This
Subscription Agreement (this “Subscription Agreement”) is being delivered to the purchaser identified on the
signature page to this Agreement (the “Undersigned” or “Subscriber”) in connection with
its investment in the securities of Mateon Therapeutics, Inc., a Delaware corporation (the “Company”). The
Company is conducting a private placement (the “Offering”) of a minimum of 40 and a maximum of 100 Units (the
“Units”), each of which consists of 25,000 shares of the Common Stock of the Company’s wholly owned subsidiary
called EdgePoint AI, Inc., a Delaware corporation (“EdgePoint”), and one note issued by the Company (a “Note”
and collectively, the “Notes”), in the principal amount of $25,000.00, bearing annual interest at the rate
of 16%. Each Note will be convertible into up to 25,000 shares of EdgePoint’s Common Stock (conversion price $1.00 per share)
or up to 138,889 shares of Mateon’s Common Stock (conversion price approximately $0.18 per share), subject to applicable
anti dilution provisions. Each Unit will also consist of 100,000 (the “Warrants”), 50,000 Warrants (the “EdgePoint
Warrants”) each to purchase one share of EdgePoint’s Common Stock at $1.00 per share, and 50,000 Warrants (the “Company
Warrants”) each to purchase one share of Mateon’s Common Stock at $0.20 per share. The the exercise price of each
Warrant will be subject to applicable anti dilution provisions set forth therein and, except as set forth in the next succeeding
sentence, each Warrant will be exercisable for three years after issuance. Each time EdgePoint Warrants are exercised a comparable
number of Company Warrants, or parts thereof, will terminate and each time Company Warrants are exercised a comparable number
of EdgePoint Warrants, or parts thereof, will terminate.


 


This
will acknowledge that the Subscriber hereby agrees to irrevocably purchase from the Company_Unit(s) as set forth in the Subscription
Signature Section below in accordance with the terms of this Subscription Agreement and Investment Letter (the “Subscription
Agreement”) and pursuant to the terms and conditions set forth in the Confidential Offering Memorandum dated ______________________
(Date), including Appendices attached thereto (the “Memorandum”).


 




    	Appendix H, Page 1



     


    

 


 1. Terms of the Offering.




 


The
Offering is being made on a “best efforts, all or none” basis with respect to the first 40 Units, and, thereafter,
on a “best efforts only” basis until the remaining 60 Units are sold, the Company terminates the Offering, which it
can do in its complete discretion at any time, or the Offering Period, as hereinafter defined, expires, whichever occurs first
(the “Termination Date”). Unless at least 40 Units (the “Minimum”) are sold on or before June 30,
2020, or September 30, 2020 if extended by the Company and the Placement Agent (the “Offering Period”) and
paid for with collected funds received in escrow as noted in the next succeeding paragraph within two Business Days thereafter,
the Offering will terminate and all funds collected from subscribers will be promptly returned to them without interest thereon
or deduction therefrom. A “Business Day” means any day except Saturday, Sunday and any day that shall be a federal
legal holiday or a day on which banking institutions in the State of New York are authorized or required by law or other governmental
action to close. Persons affiliated and/or otherwise related to the Company may purchase Units in the Offering and the Units purchased
by them will be included in the number of Units needed to satisfy the Minimum. The Placement Agent and persons affiliated with
it also may purchase Units in the Offering but the Units purchased by them will not be included in the number of Units needed
to satisfy the Minimum.


 


Because
the Minimum of forty Units must be sold in order to make the Offering effective, all funds received will be held in escrow
with Texas Capital Bank, N.A. (the “Escrow Agent”). No funds will be remitted to the Company until at
least forty Units have been sold and paid for. Thereafter, funds will continue to be held in escrow and released to the
Company at each subsequent closing, which shall be at the discretion of the Company and the Placement Agent and which shall
occur on the earlier of June 30, 2020, which date may be extended to September 30, 2020, by agreement between the Company and
the Placement Agent, or when all 100 Units on an accumulative basis have been sold and paid for (each a
“Closing” and, collectively, the “Closings”) against delivery of the appropriate number
of subscribed Units. Each Closing of the purchase and sale of the Units following acceptance by the Company of subscriptions,
as evidenced by the Company’s execution of the applicable Subscription Agreements, shall take place at the Placement
Agent’s offices, or such other place as the Placement Agent and the Company shall determine, on such date as the
Placement Agent and the Company shall determine. The date on which a Closing is consummated is the “Closing
Date.”


 


The
Offering is being made only to “accredited investors” as defined under Regulation D under the Securities Act and up
to 35 non-accredited investors. It is being conducted pursuant to the exemption from the registration provisions of the Securities
Act set forth in Section 4(a)(2) thereof and applicable Rules and Regulations promulgated thereunder, including Rule 506(b) of
Regulation D. Section 4(a)(2) requires, among other things, that each purchaser acquire the Units, and Notes, Common Stock and
Warrants which are a part thereof, and the Common Stock underlying the Notes and the Warrants (collectively, the “Underlying
Securities”) with investment intent and not with a view to distribution. The Units being offered hereby and the Underlying
Securities will be “restricted securities” under the Securities Act and may not be resold publicly except in compliance
with Rule 144 promulgated thereunder or unless subsequently registered.


 


Although
the Common Stock is traded on the OTCQB Marketplace under the symbol “MATN,” there is no public market for the Units,
the Notes, EdgePoint’s Common Stock or the Warrants and, except for EdgePoint’s Common Stock, it is not anticipated
that a public trading market for them will ever develop.


 




    	Appendix H, Page 2



     


    

 


As
set forth above, the Company has agreed to file a registration statement with the Commission covering the Underlying Securities,
but cannot assure that such a filing will be made or, if it is, that it will be declared effective by the Commission. In the event,
however, that the registration statement is declared effective, the Company cannot assure that the Underlying Securities will
be readily tradable.


 


ACCORDINGLY,
THE UNDERSIGNED UNDERSTANDS AND ACKNOWLEDGES THAT, EVEN AFTER THE TERMINATION OF THE RESALE RESTRICTION PERIODS ON THE UNITS AND
THE UNDERLYING SECURITIES, AND/OR THE UNDERLYING SECURITIES ARE REGISTERED, SHE/HE MAY BE UNABLE TO RESELL THESE SECURITIES FOR
A SIGNIFICANT PERIOD OF TIME, IF EVER.


 


Execution
of this Subscription Agreement shall constitute an offer by the Undersigned to purchase the number of Units set forth in the Subscription
Signature Section below on the terms specified herein. If the Undersigned’s offer is accepted, the Company will execute
a copy of the Signature Section and return it to the Undersigned.


 


 2. The Placement Agent.




 


The
Placement Agent, a member firm of the Financial Industry Regulatory Authority (“FINRA”), is acting as the exclusive
placement agent for the Company in placing this Offering. If all of the Units are sold, the Company will receive gross proceeds
of $5,000,000 less the expenses of this Offering. Management estimates that these expenses, including the fee and expense allowance
payable to the Placement Agent described below, will be approximately $10,000.


 


The
Placement Agent will receive a fee equal to 10%, due diligence fee of up to $150,000, and will also reimburse the Placement
Agent for all reasonable out-of-pocket expenses incurred by Agent in performing its services hereunder, including reasonable
attorney’s fees incurred by the Placement Agent in connection with a Placement in an amount not to exceed $10,000. The
Company will also grant to the Placement Agent, for nominal consideration, a warrant, exercisable over a five-year period
commencing on the final Closing Date of the Offering, to purchase such number of Units, including the Notes, the EdgePoint
Common Stock and the Warrants included therein, as shall equal 10% of the number of Units sold in the Offering at an exercise
price equal to 100% of the Unit offering price.


 


The
undersigned understands that, except as may be required by applicable regulations of FINRA, the Placement Agent has not independently
verified the information provided to her/him with respect to the Company. Accordingly, there is no representation by the Placement
Agent as to the completeness or accuracy of such information.

 3. Suitability Requirements; Transferability.

financial resources and who, alone or together with their purchaser representatives (see the definition below), have such knowledge
and experience in financial and business matters that they are capable of evaluating the merits and risks of purchasing the Units.
Satisfaction of these suitability standards by a person does not represent a determination by the Company that the Units are a
suitable investment for such person. Each person must consult such person’s own professional advisors in order to determine
the suitability of the investment. The Company may make or cause to be made such further inquiry and obtain such additional information
as it deems appropriate with regard to the suitability of prospective investors.


 


The
Undersigned must complete, sign and return a Purchaser Questionnaire to the Company in order to assist it in determining whether
the Undersigned is an accredited or sophisticated investor and satisfies the minimum suitability requirements. The form of Purchaser
Questionnaire is attached to the Confidential Offering Memorandum as Appendix E.

reasonably believes satisfies all of the following conditions:

(ii) A
trust or estate in which the purchaser representative and any persons related to her/him as specified in Paragraph (h)(1)(i) or
(h)(1)(iii) of Rule 501 under Regulation D, collectively have more than 50 percent of the beneficial interest (excluding contingent
interest) or of which the purchaser representative serves as trustee, executor, or in any similar capacity; or


 


(iii) A
corporation or other organization of which the purchaser representative and any persons related to her/him as specified in Paragraph
(h)(1)(i) or (h)(1)(ii) of Rule 501, collectively are the beneficial owners of more than 50 percent of the equity securities (excluding
directors’ qualifying shares) or equity interests;


 


(b) she/he
has such knowledge and experience in financial and business matters that she/he is capable of evaluating, alone, or together with
other purchaser representatives of the purchaser or together with the purchaser, the merits and risks of the prospective investment;


 


(c) she/he
is acknowledged by the purchaser in writing, during the course of the transaction, to be her/his purchaser representative in connection
with evaluating the merits and risks of the prospective investment; and


 


(d) she/he
discloses to the purchaser in writing prior to the acknowledgment specified in Paragraph (h)(3) of Rule 501, any material relationship
between herself/himself or her/his affiliates and the Company or its affiliates that then exists, that is mutually understood
to be contemplated or that has existed at any time during the previous two years and any compensation received or to be received
as a result of such relationship.

The Company has no direct or indirect subsidiaries other than those set forth in the SEC Documents, as defined below in Subsection
5(e), (individually a “Subsidiary” and, collectively, the “Subsidiaries”). Except as
disclosed in the SEC Documents, the Company owns, directly or indirectly, all of the capital stock of each Subsidiary free and
clear of any and all liens, charges, encumbrances, security interests, rights of first refusal or other restrictions of any kind
(each a “Lien” and, collectively, “Liens”), and all the issued and outstanding shares of
capital stock of each Subsidiary are validly issued and are fully paid, non- assessable and free of preemptive and similar rights.


 


(b) Organization
and Qualification. Each of the Company and each Subsidiary is an entity duly incorporated or otherwise organized, validly
existing and in good standing under the laws of the jurisdiction of its incorporation or organization (as applicable), with 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 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 each Subsidiary 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, could not, individually or in the aggregate, have or reasonably be expected to result in (i) an adverse effect
on the legality, validity or enforceability of any agreement or other document executed by the Company relating to the Offering
(each a “Transaction Document” and, collectively, the “Transaction Documents”), (ii) a material
and adverse effect on the results of operations, assets, prospects, business or condition (financial or otherwise) of the Company
and the Subsidiaries, taken as a whole, or (iii) an adverse impairment to the Company’s ability to perform on a timely basis
its obligations under any Transaction Document (any of (i), (ii) or (iii), a “Material Adverse Effect”).


 


(c) Authorization;
Enforcement. The Company has the requisite corporate power and authority to enter into and to consummate the transactions
contemplated by each of the Transaction Documents and otherwise to carry out its obligations thereunder. The execution and delivery
of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated thereby have been
duly authorized by all necessary corporate action on the part of the Company and no further corporate action is required by the
Company in connection therewith. 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, will constitute the valid and binding obligation of the Company enforceable
against the Company in accordance with its terms, except as rights to indemnity and contribution may be limited by state or federal
securities laws or the public policy underlying such laws, except as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and except
as enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a
proceeding in equity or at law).


 




    	Appendix H, Page 6



     


    

 


(d) No
Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by
the Company of the transactions contemplated thereby do not 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, 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) 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

Effect.

(collectively, the “SEC Documents”) required to be filed by it with the Commission pursuant to the Securities
Exchange Act of 1934 (the “Exchange Act”), in a timely manner within the past three years. The SEC Documents
have complied in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission
promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the Commission,
contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary
in order to make the statements therein, in light of the circumstances under which they were made, not misleading. As of their
respective dates, to the best of the Company’s knowledge during those respective dates, the Company’s financial statements

rules and regulations of the Commission with respect thereto. Such financial statements have been prepared in accordance with

statements, to normal year-end audit adjustments). The Company has not received notification from the Commission, and/or any federal
or state securities bureaus that any investigation (informal or formal), inquiry or claim is pending, threatened or in process

Act.


 


(h) Employment
Matters. The Company and the Subsidiaries are in compliance with all federal, state, local and foreign laws and regulations
respecting employment and employment practices, terms and conditions of employment and wages and hours except where failure to
be in compliance would not have a Material Adverse Effect. Neither the Company nor any Subsidiary is bound by or subject to (and
none of the Company’s or any of its Subsidiaries’ assets or properties are bound by or subject to) any written or
oral, express or implied, contract, commitment or arrangement with any labor union, and no labor union has requested or, to the
Company’s knowledge, has sought to represent any of the employees, representatives or agents of the Company or the Subsidiaries.

Permits. The Company and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal,

only to the extent that the Company or such Subsidiaries have set aside on their books provisions reasonably adequate for the
payment of all unpaid and unreported taxes) and have timely paid all taxes and other governmental assessments and charges that
are material in amount, shown or determined to be due on such returns, reports and declarations, except those being contested
in good faith, and have set aside on their books provisions reasonably adequate for the payment of all taxes for periods subsequent

SUBSCRIPTION
SIGNATURE SECTION MATEON THERAPEUTICS, INC.


 


_______________ (Date)


SUBSCRIPTION
AGREEMENT AND INVESTMENT LETTER


 


The
undersigned (the “Undersigned” or “Subscriber”) hereby purchases Units from Mateon Therapeutics,
Inc. (the “Company”) pursuant to the terms of the Subscription Agreement dated ______________________ (Date)
(the “Subscription Agreement”) of which this Subscription Signature Section is a part. All terms in this
Subscription Signature Section have the meanings defined elsewhere in this Subscription Agreement.


 


Subscriber
Representations.


 


The
Subscriber hereby acknowledges, represents and warrants to, and agrees with the Company as follows:


 


(a)
The Subscriber is acquiring the Units and Underlying Securities for the Subscriber’s own account as principal for investment
and not with a view to resale, distribution or fractionalization in whole or in part, and has no current agreement, understanding
or arrangement to subdivide, sell, assign or otherwise dispose of all or any part of the Units and/or Underlying Securities and
understands that there is no public market for the Units, the Notes, EdgePoint’s Common Stock, or the Warrants, and, except
for EdgePoint’s Common Stock, none is expected to develop in the foreseeable future, if ever. She/he does not have any contract,
undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third
Person, with respect to the Units and/or Underlying Securities for which she/he is subscribing.


 


(b)
The Units and Underlying Securities that the Subscriber is purchasing and the Underlying Securities into which the Notes may be
converted and the Warrants may be exercised have not been registered under the Securities Act or qualified under applicable state
securities laws and the registration provisions of the Securities Act as well as the qualification provisions of such state laws
thereof restrict their transferability. Based upon the representations and agreements being made by her/him herein, the Subscriber
acknowledges that the offering and sale of the Units are intended to be exempt from registration under the Securities Act by virtue
of Section 4(a)(2) thereof and applicable Rules and Regulations adopted thereunder, and that:


 


1.
the Undersigned’s Units and Underlying Securities cannot be sold, pledged, assigned or otherwise disposed of unless they
are subsequently registered under the Securities Act and/or qualified under applicable state securities laws or, in the reasonable
opinion of the Company’s counsel, an exemption from such registration and/or qualification is available;


 


2.
Sales or transfers of the Undersigned’s Units and Underlying Securities are further restricted by the provisions of state
securities laws;


 


3.
the Company is under no obligation to assist the Undersigned in complying with any exemption from registration under the Securities
Act or qualification under any state securities law, or, except
as may be provided in the Registration Rights Agreement, to register the Units or Underlying Securities on the Undersigned’s
behalf;


 






    	Appendix H, Page 14



     


    

 


4.
the certificates or other documentation representing the Undersigned’s Underlying Securities will bear, in substance, the
following legend:


 


These
securities have not been registered under the Securities Act of 1933. They may not be sold or transferred in the absence of an
effective Registration Statement under that Act without an opinion of counsel satisfactory to the Company that such Registration
is not required.;


 


5.
the Company will place stop-transfer instructions on its books and with the transfer agent of its securities with respect to the
Units and Underlying Securities registered in the name of the Undersigned or beneficially owned by her/him.


 


The
Undersigned further acknowledges that the basis for these exemptions may not be available if, notwithstanding such representations,
she/he only intends to hold these securities for a fixed or determinable period in the future, or until the market price rises
or falls and she/he hereby represents and warrants that she/he does not have any such intention.


 


(c)
The Subscriber: (A) by herself/himself or together with her/his Purchaser Representative, if any, has such knowledge and experience
in financial, business and tax matters that she/he is capable of evaluating the merits of the prospective purchase of the Units
and making an investment decision with respect to the Company and EdgePoint; (B) has had substantial experience in previous private
and public purchases of speculative securities and is not relying on the Company, the Placement Agent, or any of their respective
affiliates or attorneys with respect to economic, tax or other considerations involved in this investment; and (C) is able to
bear the economic risk of this investment (i.e., she/he can afford a complete loss of her/his investment). In this
regard, her/his overall commitment to investments, which are not readily marketable, is not disproportionate to her/his net worth,
and her/his purchase of the Units will not cause such overall commitment to become excessive.


 


(d)
The Subscriber understands and acknowledges that an investment in the Company and EdgePoint is speculative and subject to many
risks. In this regard, the Company cannot assure her/him that all of the Units will be sold. Accordingly, the Company’s
operations and financial condition will be adversely affected to the extent that less than all of the Units are sold, especially
because it currently has no commitment for any financing.


 


(e)
_________ (insert name of Purchaser Representative: if none, leave blank) has acted as the Undersigned’s Purchaser
Representative for purposes of the private placement exemption under the Securities Act. If the Undersigned has appointed a
Purchaser Representative (which term is used herein with the same meaning as given in Rule 501(h) of Regulation D), she/he
has been advised by her/his Purchaser Representative as to the merits and risks of an investment in the Company in general
and the suitability of the Units as an investment for the Undersigned in particular, and is aware that the Purchaser
Representative may be receiving compensation from the Company in connection with the services being performed by such
Purchaser Representative for the Undersigned relating to her/his purchase of the Units.

(f)
If applicable, the Subscriber has reviewed carefully the definition of “accredited investor” as set forth below, and
the particular subparagraph or subparagraphs by which the Undersigned qualifies as such is (are) checked by her/him below.


 


(g)
The Subscriber has carefully reviewed the Confidential Offering Memorandum dated ______________________ (Date) including
the Risk Factors section set forth therein and in the SEC Documents


 


THE
UNDERSIGNED UNDERSTANDS THAT, BECAUSE OF THE SIGNIFICANT RISK FACTORS SET FORTH IN THE CONFIDENTIAL OFFERING MEMORANDUM AND IN
THE SEC DOCUMENTS, INCLUDING BUT NOT LIMITED TO THE RISK FACTORS SET FORTH IN THE DESCRIPTION OF RISK FACTORS DISCLOSED IN THE
CONFIDENTIAL OFFERING MEMORANDUM AND THE SEC DOCUMENTS, IF THE OFFERING IS CONSUMMATED, SHE/HE COULD LOSE HER/HIS ENTIRE INVESTMENT.
