To the Board of Directors of InventaBioTech Inc.: This Subscription Agreement and Investment Letter (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 InventaBioTech Inc. a Colorado corporation (the "Company"). The Company is conducting a private placement (the "Offering") of a minimum principal amount of $100,000 and a maximum principal amount of $1,000,000 of Convertible Promissory Notes (the "Notes"), each of which is convertible into: (i) units (the "Units") consisting of the Company's equity securities the Company plans to offer for sale in a private financing transaction or (ii) shares of Common Stock of the Company, $0.001 par value per share (the "Common Stock"), on terms set forth in the Notes. For purposes of this Agreement, the term "Securities" shall refer to the Notes and to: (i) the Units into which they may be converted or (ii) the Common Stock into which they may be converted (collectively, the "Underlying Securities"). This will acknowledge that the Subscriber hereby agrees to irrevocably purchase from the Company a Note in the principal amount set forth in the Subscription Signature Section below in accordance with the terms of this Subscription Agreement. 1. Terms of the Offering. The Offering is being made on a "best efforts, all or none" basis with respect to the first $100,000 in principal amount of the Notes, and, thereafter, on a "best efforts only" basis until the remaining $9000,000 in principal amount of the Notes is 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 $100,000 in principal amount of the Notes (the "Minimum") is sold on or before February 28, 2019, or March 31, 2019 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, including existing shareholders, may purchase Notes in the Offering and the Notes purchased by them will be included in the number of Notes needed to satisfy the Minimum. The Placement Agent and persons affiliated with it also may purchase Notes in the Offering but the Notes purchased by them will not be included in the number of Notes needed to satisfy the Minimum. Because the Minimum of $100,000 in principal amount of the Notes must be sold in order to make the Offering effective, all funds received will be held in escrow with JP Morgan Chase Bank (the "Escrow Agent"). No funds will be remitted to the Company until at least $100,000 in principal amount of the Notes has 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 each of which shall occur prior to the earlier of: (i) February 28, 2019, which date may be extended to March 31, 2019, by agreement between the Company and the Placement Agent; or (ii) when all $1,000,000 in principal amount of the Notes on has been sold and paid for (each a "Closing" and, collectively, the "Closings") against delivery of the appropriate number of subscribed Notes. Each Closing of the purchase and sale of the Notes 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. 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 Notes and Underlying Securities with investment intent and not with a view to distribution. The Notes 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 OTC Pink marketplace there is no public market for the Notes and it is not anticipated that a public trading market for them will ever develop. The Company's common stock is listed under the symbol "INVB." ACCORDINGLY, THE UNDERSIGNED UNDERSTANDS AND ACKNOWLEDGES THAT, EVEN AFTER THE TERMINATION OF THE RESALE RESTRICTION PERIODS ON THE NOTES AND THE UNDERLYING SECURITIES, AND/OR THE COMMON STOCK UNDERLYING THE UNITS ARE REGISTERED, SHE/HE MAY BE UNABLE TO RESELL THESE SECURITIES FOR A SIGNIFICANT PERIOD OF TIME, IF EVER AND THERE IS NO ASSURANCE THAT THE NOTES WILL BE REPAID IN ACCORDANCE WITH THEIR TERMS IF EVER. Execution of this Subscription Agreement shall constitute an offer by the Undersigned to purchase the number of Notes set forth in the Subscription Signature Section below on the terms 2 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 Notes are sold, the Company will receive gross proceeds of $1,000,000 less the Placement Agent's expenses. Management estimates that the Placement Agent's expenses, including the fee and expense allowance payable to the Placement Agent described below, will be approximately $110,000 if the Offering is fully sold. The Placement Agent will receive a fee equal to 8%, and a non-accountable expense allowance up to 3% of the aggregate gross purchase price of the Notes sold. 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 Notes as shall equal 8% of the number of Notes sold in the Offering at an exercise price equal to $0.20. 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. An investment in the Company involves a high degree of risk and is suitable only for those qualified persons who have substantial 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 Notes. Satisfaction of these suitability standards by a person does not represent a determination by the Company that the Notes 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. Because this Offering is being made only to accredited 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 hereto as Exhibit B. The term "purchaser representative" means any person who satisfies all of the following conditions or who the Company reasonably believes satisfies all of the following conditions: (a) she/he is not an affiliate, director, officer or other employee of the Company or beneficial owner of 10% or more of any class of the Company's equity securities, except where the purchaser is: 3 (1) A relative of the purchaser representative by blood, marriage or adoption and not more remote than a first cousin; (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. If the Undersigned is using a purchaser representative, the purchaser representative must complete, execute and return a Purchaser Representative's Questionnaire to the Company. A form of Purchaser Representative's Questionnaire is attached hereto as Exhibit C. 4. Subscription Procedure and Effect. The subscription price shall be payable upon execution of this Subscription Agreement in accordance with the terms set forth herein.

The Company, in its sole discretion, has the right to accept or reject this Subscription Agreement in whole or in part and accept Subscription Agreements other than in the order received.

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 Note and any Underlying Securities for which the Note may be converted 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 Note and/or Underlying Securities and understands that there is no public market for the Notes, and 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 Note and/or Underlying Securities for which she/he is subscribing. (b) The Note that the Subscriber is purchasing and the Underlying Securities for which the Note may be converted 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 Notes 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 Note and Underlying Securities cannot be sold, pledged, assigned or otherwise disposed of unless they are subsequently registered under the Securities Act and 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 Note 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; 13 4. the certificates or other documentation representing the Undersigned's Note and Underlying Securities will bear, in substance, the following legend: NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE CONVERTIBLE HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933 (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; 5. the Company will place stop-transfer instructions on its books and with the transfer agent of its securities with respect to the Note 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 Note and making an investment decision with respect to the Company; (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 Note will not cause such overall commitment to become excessive. (d) The Subscriber understands and acknowledges that an investment in the Company is speculative and subject to many risks. In this regard, the Company cannot assure her/him that all of the Notes will be sold. Accordingly, the Company's operations and financial condition will be adversely affected to the extent that less than all of the Notes 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 Note as an investment for the Undersigned in 14 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 Note. (f) 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.
