Attention: Daniel Tsai

Ladies and Gentlemen:

The initial public offering (the “IPO”) of PTK Acquisition Corp., a Delaware corporation (the “Company”) is expected, as of the date hereof, to generate aggregate gross proceeds to the Company of $100,000,000 (or $115,000,000 if the over-allotment option is exercised in full by the underwriters) by selling Units, each currently contemplated to consist of one share of common stock, par value $0.0001 per share, of the Company (the “Shares”), and one redeemable warrant to acquire ¹⁄₂ of a Share, at a purchase price of $10.00 per Unit. The precise structure of the Units will be determined by the Company prior to the IPO. We acknowledge that Primerose Development Group Ltd. (the “Subscriber” or “you”) have/has expressed an intention to purchase up to 1,000,000 Units in the IPO (the “IPO Securities”) which Units will include up to 1,000,000 Shares (the “IPO Shares”).

We are pleased to hereby accept the offer you have made to purchase up to an aggregate of 1,000,000 Shares, consisting of the IPO Shares and a number of shares equal to the difference between 1,000,000 and the number of IPO Shares actually purchased in the IPO (the “Additional Shares”). You agree that you will continue to hold the IPO Shares and any Additional Shares on the date of the Subscription Notice (as defined below) in connection with the consummation of the Company’s initial business combination (the “Business Combination”) and will not redeem any IPO Shares. The number of Shares and warrants being purchased hereunder being the sum of the IPO Securities and the Additional Shares, collectively, are hereinafter referred to as the “Securities”. The terms on which the Company is willing to sell the Securities to the Subscriber, and the Company’s and the Subscriber’s agreements regarding such Securities, are set forth in this agreement (this “Agreement”) and are as follows:

1. Purchase of the Securities. The purchase price for the Additional Shares (the “Purchase Price”) shall be $10.00 multiplied by the number of Additional Shares purchased hereunder, for an aggregate Purchase Price of, when considered together with any IPO Securities purchased by the Subscriber, up to $10,000,000. In exchange for the Purchase Price, the Company agrees to sell the Additional Shares to the Subscriber and the Subscriber hereby agrees to purchase the Additional Shares either in a private placement from the Company or in open market purchases arranged by the Company or its advisors, subject to the terms and subject to the conditions set forth in this Agreement.

2. Representations, Warranties and Agreements.

2.1.2 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Subscriber of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber is a party, (iii) any law, statute, rule or regulation to which the Subscriber is subject, or (iv) any agreement, order, judgment or decree to which the Subscriber is subject.

rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity).

2.1.4 Experience, Financial Capability and Suitability. Subscriber is: (i) sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Securities and (ii) able to bear the economic risk of its investment in the Securities for an indefinite period of time because the Securities have not been registered under the Securities Act of 1933, as amended (“Securities Act”) and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available. Subscriber is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests. Subscriber must bear the economic risk of this investment until the Securities are sold pursuant to: (i) an effective registration statement under the Securities Act or (ii) an exemption from registration available with respect to such sale.

Prior to the execution of this Agreement, the Subscriber has had the opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity to obtain additional information to verify the accuracy of all information so obtained. In determining whether to make this investment, Subscriber has relied solely on Subscriber’s own knowledge and understanding of the Company and its business based upon Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person has been authorized to give any information or to make any representations which were not furnished pursuant to this Section 2 and Subscriber has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its operations and/or its prospects.

Subscriber agrees that if any transfer of its Securities or any interest therein is proposed to be made, as a condition precedent to any such transfer, Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption, the Subscriber agrees not to resell the Securities subject to such restriction. Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be available to the Subscriber for the resale of restricted securities until one (1) year following consummation of the Business Combination, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions.

2.1.9 No Governmental Consents. No governmental, administrative or other third party consents or approvals are required, necessary or appropriate on the part of Subscriber in connection with the transactions contemplated by this Agreement, other than the filing of a Form D with the Securities and Exchange Commission and such state Blue Sky, FINRA and NASDAQ consents and approvals as may be required.

6.9 Severability. In the event that any court of competent jurisdiction shall determine that any provision, or any portion thereof, contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so limited shall remain in full force and effect.

6.10 No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Agreement by a party hereto,

nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand.

6.11 Survival of Representations and Warranties.

6.13 Counterparts. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. This Agreement may be executed in one 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 any other form of electronic delivery, 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 signature page were an original thereof.

6.14 Construction. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant.

7. Indemnification. Each party shall indemnify the others against any reasonable loss, cost or damages (including reasonable attorney’s fees and expenses) incurred as a result of such party’s breach of any representation, warranty, covenant or agreement in this Agreement.

8. Term. The Subscriber’s obligation to acquire the Securities hereunder, and the Company’s obligation to sell the Securities hereunder, shall be in effect until the earlier of (i) the consummation of the Business Combination within the time frame permitted by the Company’s amended and restated certificate of incorporation (the “Charter”), which, as of the date hereof, is expected to be 24 months from the consummation of the IPO, including any extensions beyond such term effected pursuant to the terms of the Charter, and (ii) the liquidation of the Company in the event that the Company is unable to consummate the Business Combination within the time frame permitted by the Charter (including any extensions).

9. Disclosure. The Subscriber hereby acknowledges that this Agreement will be filed with the Securities and Exchange Commission and the Company will disclose the terms of this Agreement to potential IPO investors and to potential Business Combination targets.

10. Waiver of Claims Against Trust. The Subscriber hereby acknowledges that it is aware that the Company will establish a trust account (the “Trust Account”) for the benefit of its public stockholders upon the closing of the IPO. The Subscriber, for itself and its affiliates, hereby agrees that it has no right, title, interest or claim of any kind in or to any monies held in the Trust Account, or any other asset of the Company as a result of any liquidation of the Company, except for redemption and liquidation rights, if any, the Subscriber may have in respect of any shares issued as part of the Shares sold in the IPO (“Public Shares”) held by the Subscriber. The Subscriber hereby agrees that it shall have no right of set-off or any right, title, interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have now or in the future, except for redemption and liquidation rights, if any, the Subscriber may have in respect of any Public Shares held by the Subscriber. In the event the Subscriber has any Claim against the Company under this Agreement, the Subscriber shall pursue such Claim solely against the Company and its assets outside the Trust

Account and not against the property or any monies in the Trust Account, except for redemption and liquidation rights, if any, the Subscriber may have in respect of any Public Shares held by the Subscriber.
