Re: Initial Public Offering

Ladies and Gentlemen:

This letter (this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by and among Prime Number Acquisition I Corp., a Delaware corporation (the “Company”), Prime Number Capital LLC as the underwriter (the “Underwriter”), relating to an underwritten initial public offering (the “Public Offering”), of up to 6,000,000 of the Company’s units (including up to 900,000 units that may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one share of the Company’s Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), and one-half of one redeemable warrant. Each Warrant (each, a “Warrant”) entitles the holder thereof to purchase one share of Class A Common Stock at a price of $11.50 per share, subject to adjustment. No fractional warrants will be issued upon separation of the units and only whole warrants will trade. Accordingly, unless you purchase at least two units, you will not be able to receive or trade a whole warrant. The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the “Commission”) and the Units have been approved to be listed on the Nasdaq Capital Market. Certain capitalized terms used herein are defined in paragraph 12 hereof.

In order to induce the Company and the Underwriter to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Prime Number Acquisition LLC (“Sponsor A”), Glorious Capital LLC (“Sponsor B,” together with Sponsor A, “Sponsors”) , officers and directors, and each of the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team or a personnel of the Company or a designee of them (each, an “Insider” and collectively, the “Insiders”), hereby agrees with the Company as follows:

1.            Each of the Insiders agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection with such proposed Business Combination, it, he or she shall (i) vote any shares of Capital Stock owned by it, him or her in favor of any proposed Business Combination and (ii) not redeem any shares of Common Stock owned by it, him or her in connection with such stockholder approval. If the Company engages in a tender offer in connection with any proposed Business Combination, each Insider agrees that it, he or she will not seek to sell its, his or her shares of Common Stock to the Company in connection with such tender offer.

2.            Each of the Insiders agrees that in the event that the Company fails to consummate a Business Combination within 18 months from the closing of the Public Offering or such later period approved by the Company’s stockholders in accordance with the Company’s amended and restated certificate of incorporation, the Sponsors and each Insider shall take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than 10 business days thereafter, subject to lawfully available funds therefor, redeem 100% of the Class A Common Stock sold as part of the Units in the Public Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to $50,000 of interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public Stockholders’ rights as stockholders of the Company (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable law. Each Insider agrees not to propose any amendment to the Company’s amended and restated certificate of incorporation that would modify (i) the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within 12 months from the closing of the Public Offering (or up to 18 months if the Company extends the period of time to consummate a business combination) or (ii) the other provisions relating to stockholders’ rights or pre-initial business combination activities, unless the Company provides its Public Stockholders with the opportunity to redeem their Offering Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of amounts released for payment of taxes) divided by the number of then outstanding Offering Shares. Each Insider agrees to waive its redemption rights with respect to shares of Capital Stock owned by it in connection with a stockholder vote to approve an amendment to the Company’s amended and restated certificate of incorporation (A) to modify the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within 12 months from the closing of the Public Offering (or up to 18 months if the Company extend the period of time to consummate a business combination) or (B) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity.

3.            Each Insider acknowledges that it, he or she 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 with respect to the Founder Shares held by it, him or her. Each Insider hereby further waives, with respect to any shares of Common Stock held by it, him or her, if any, any redemption rights it, he or she may have in connection with the consummation of a Business Combination, including, without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination or in the context of a tender offer made by the Company to purchase shares of Common Stock (although the Insiders and their respective affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares they hold if the Company fails to consummate a Business Combination within 18 months from the closing of the Public Offering ).

4.            In the event of the liquidation of the Trust Account, the Sponsors (which for purposes of clarification shall not extend to any other shareholders, members or managers of the Sponsors) agree to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which the Company may become subject as a result of any claim by (i) any third party (other than the Company’s independent accountants) for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement for a Business Combination agreement (a “Target”); provided, however, that such indemnification of the Company by the Sponsors shall apply only to the extent necessary to ensure that such claims by a third party for services rendered (other than the Company’s independent public accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.20 per share of the Offering Shares or (ii) such lesser amount per share of the Offering Shares held in the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amount of interest earned on the property in the Trust Account which may be withdrawn to pay taxes, except as to any claims by a third party (including a Target) who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Sponsors shall not be responsible to the extent of any liability for such third party claims. The Sponsors shall have the right to defend against any such claim with counsel of their choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Sponsors, the Sponsors notify the Company in writing that they shall undertake such defense.

5.            To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 900,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsors agree to forfeit, at no cost, a number of Founder Shares in the aggregate equal to the product of 225,000 multiplied by a fraction, (i) the numerator of which is 900,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 900,000. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the Insiders will own an aggregate of 20.0% of the Company’s issued and outstanding shares of Capital Stock after the Public Offering (excluding the sale of Private Shares and assuming that the Insiders do not purchase any Offering Shares or Units in the Public Offering).

6.            Sponsor A hereby agrees to transfer up to 465,000 Founder Shares to financial advisors, finders or consultants in connection with the initial Business Combination of the Company who are not affiliated with the Company or any Insider.

7.            Each Insider hereby agrees and acknowledges that: (i) the Underwriter and the Company would be irreparably injured in the event of a breach by such Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 6, 8(a), 8(b), and 10 of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

8.            (a) The Insiders agree that they shall not Transfer 50% of the Founder Shares until the earlier to occur of: (A) six months after the completion of the Company’s initial Business Combination, or (B) the date on which the closing price of the Company’s Class A Common Stock equals or exceeds $12.50 per share (as adjusted for share splits, share dividends, reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period commencing after the completion of the Company’s initial Business Combination; and shall not Transfer the remaining 50% of the founder shares until the six months after the completion of the Company’s initial Business Combination, or earlier, in either case, if, subsequent to the Company’s initial Business Combination, the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property (the “Founder Shares Lock-up Period”).

(b) The Insiders agree that they shall not Transfer any Private Shares or Working Capital Shares until after 30 days after the completion of a Business Combination (the “Private Shares Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

(c) Notwithstanding the provisions set forth in paragraphs 8(a) and (b), Transfers of the Founder Shares, Private Shares, or Working Capital Shares that are held by the Insiders or any of their permitted transferees (that have complied with this paragraph 8(c)), are permitted (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, Sponsors, any affiliates of the Sponsors, or any of their affiliates, officers, directors, direct and indirect equity holders; (b) in the case of an individual, by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, transfers pursuant to a qualified domestic relations order; (e) transfers by private sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which the securities were originally purchased; (f) transfers in the event of the Company’s liquidation prior to the completion of an initial Business Combination; and (g) transfers by virtue of the laws of the State of Delaware or the Sponsors’ limited liability company agreement upon dissolution of the Sponsors; provided, however, that in the case of clauses (a) through (e) or (g), these permitted transferees must enter into a written agreement agreeing to be bound by the restrictions herein.

9.            Each Insider represents and warrants that it, he or she has never been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. Each Insider’s biographical information furnished to the Company (including any such information included in the Prospectus) is true and accurate in all respects and does not omit any material information with respect to the Insider’s background. Each Insider’s questionnaire furnished to the Company is true and accurate in all respects. Each Insider represents and warrants that: it, he or she is not subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; it, he or she has never been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities and it, he or she is not currently a defendant in any such criminal proceeding. The Company represents and warrants that, to its knowledge, (i) none of its advisors has been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked, (ii) each advisor’s biographical information furnished to the Company (including any such information included in the Prospectus) is true and accurate in all respects and does not omit any material information with respect to such advisor’s background and each advisor’s questionnaire furnished to the Company is true and accurate in all respects, (iii) none of its advisors is subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; and (iii) none of its advisors has been convicted of, or pleaded guilty to, any crime (x) involving fraud, (y) relating to any financial transaction or handling of funds of another person, or (z) pertaining to any dealings in any securities and none of its advisors is currently a defendant in any such criminal proceeding.

10.          Except as disclosed in the Prospectus and cash or other compensation to the Company’s officers or advisors to be engaged subsequent to the consummation of the Public Offering (which will be disclosed in the Company’s other filings with the Securities and Exchange Commission), neither the Sponsors nor any individual who is an officer, director or advisor of the Company as of the date hereof nor any affiliate thereof shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is), other than the following, none of which will be made from the proceeds held in the Trust Account prior to the completion of the initial Business Combination: repayment of a loan and advances up to an aggregate of $400,000 made to the Company by Sponsor A in connection the preparation of the Public Offering; reimbursement for any out-of-pocket expenses related to identifying, investigating and consummating an initial Business Combination; and repayment of loans, if any, and on such terms as to be determined by the Company from time to time, made by any of the Sponsors and/or their affiliates or designees to finance transaction costs in connection with an intended initial Business Combination or to extend the time that the Company need to complete an initial Business Combination, provided, that, if the Company does not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may be used by the Company to repay such loaned amounts so long as no proceeds from the Trust Account are used for such repayment. Up to $3,000,000 of such loans may be convertible into Class A Common Stock at a price of $10.00 per share at the option of the lender (the “Working Capital Shares”). Such shares would be identical to the Private Shares.

11.          Each Insider has full right and power, without violating any agreement to which it is bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Letter Agreement and, as applicable, to serve as an officer and/or a director on the board of directors of the Company and hereby consents to being named in the Prospectus as an officer and/or a director of the Company.
