In no event will the Company be required to net cash settle the Rights. The provisions of this Section 3.1 may not be modified, amended or deleted without the prior written consent of the Representative.

Notwithstanding the foregoing, or any provision contained in this Agreement to the contrary, in no event will the Company be required to net cash settle the Rights. The Company shall not issue fractional shares upon exchange of Rights. At the time of an Exchange Event, the Company will either instruct the Rights Agent to round up to the nearest whole share of Common Stock or otherwise inform it how fractional shares will be addressed, in accordance with Section 155 of the Delaware General Corporation Law. Each holder of a Right will be required to affirmatively convert his, her or its rights in order to receive the 1/10 of a share underlying each right (without paying any additional consideration) upon consummation of the Exchange Event.

Upon an Exchange Event in which the Company does not continue as the publicly held reporting entity, the definitive agreement will provide for the holders of Rights to receive the same per share consideration the holders of the shares of Common Stock will receive in such transaction, for the number of shares such holder is entitled to pursuant to Section 3.3.1 above.

The Rights so cancelled shall be delivered by the Rights Agent to the Company from time to time upon request.

4.2.         Procedure for Surrender of Rights . Rights may be surrendered to the Rights Agent, together with a written request for exchange or transfer, and thereupon the Rights Agent shall issue in exchange therefor one or more new Rights as requested by the registered holder of the Rights so surrendered, representing an equal aggregate number of Rights; provided, however, that in the event that a Right surrendered for transfer bears a restrictive legend, the Rights Agent shall not cancel such Right and issue new Rights in exchange therefor until the Rights Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Rights must also bear a restrictive legend.

4.3.         Fractional Rights . The Rights Agent shall not be required to effect any registration of transfer or exchange which will result in the issuance of a Right Certificate for a fraction of a Right.

5.2.         Lost, Stolen, Mutilated, or Destroyed Rights .

Any such new Right shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Right shall be at any time enforceable by anyone.

5.3.         Reservation of Common Stock . The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that will be sufficient to permit the exchange of all outstanding Rights issued pursuant to this Agreement.

INDEMNIFICATION AND CONTRIBUTION

4.1  Indemnification .

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein;  provided ,  however , that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3 Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim (other than local counsel), unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under  Section 4.1  hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action;  provided ,  however , that the liability of any Holder under this  subsection 4.1.5  shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in  subsections 4.1.1 ,  4.1.2  and  4.1.3  above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this  subsection 4.1.5  were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this  subsection 4.1.5 . No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this  subsection 4.1.5  from any person who was not guilty of such fraudulent misrepresentation.

As Representative of the Several Underwriters named in

Schedule A of the Underwriting Agreement

Gentlemen:

This letter (this “ Letter Agreement ”) is being delivered to you in accordance with the Underwriting Agreement (the “ Underwriting Agreement ”) proposed to be entered into by and between KBL Merger Corp. IV, a Delaware corporation (the “ Company ”), and Ladenburg Thalmann & Co. Inc. as representative (the “ Representative ”) of the several underwriters named therein (the “ Underwriters ”), relating to an underwritten initial public offering (the “ Public Offering ”), of 10,000,000 of the Company’s units (the “ Units ”), each comprised of one share of the Company’s common stock, par value $0.0001 per share (the “ Common Stock ”), one right to receive one-tenth of one share of Common Stock (each, a “ Right ”), and one warrant (each, a “ Warrant ”). Each Warrant entitles the holder thereof to purchase one-half of one share of Common Stock at a price of $11.50 per whole share, subject to adjustment. 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 Company shall apply to have the Units listed on the Nasdaq Capital Market. Certain capitalized terms used herein are defined in Section 11 hereof.

In order to induce the Company and the Underwriters 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, KBL IV Sponsor LLC (the “ Sponsor ”), the undersigned individuals, each of whom is a director or officer to the Company (together with the Sponsor, each an “ Insider ” and collectively, the “ Insiders ”), hereby agree with the Company as follows:

1. Each Insider 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 Common Stock owned by it, him or her in favor of such 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 owned by it, him or her to the Company in connection with such tender offer.

2. Each Insider agrees that in the event that the Company fails to consummate a Business Combination (as defined in the Underwriting Agreement) within the time period set forth in the Company’s amended and restated certificate of incorporation, as the same may be amended from time to time, 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 redeem 100% of the 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 (which interest shall be net of taxes payable and less up to $50,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any) 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 the cases of clauses (ii) and (iii) above 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 affect the substance or timing of the Company’s obligation to redeem the Offering Shares in connection with a Business Combination or if the Company does not complete a Business Combination within the time period then set forth in the Company’s amended and restated certificate of incorporation, unless the Company provides its public stockholders with the opportunity to redeem their shares of Common Stock 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 taxes payable), divided by the number of then outstanding public shares.

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 and hereby waives any claim such Insider may have in the future as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Fund for any reason whatsoever except in each case with respect to the Insider’s right to a pro rata interest in the proceeds held in the Trust Fund for any Offering Shares such Insider may hold.

3. Subject to the provisions set forth in paragraphs 7(a) and (b) below, during the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider shall not (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, file (or participate in the filing of) a registration statement with the Commission or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder, with respect to any Units, shares of Common Stock, Rights, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, if any, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Units, shares of Common Stock, Rights, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, if any, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii). The foregoing sentence shall not apply to the registration of the offer and sale of Units contemplated by the Underwriting Agreement and the sale of the Units to the Underwriters. The Sponsor and each of the Insiders acknowledges and agrees that, prior to the effective date of any release or waiver, of the restrictions set forth in this paragraph 3 or paragraph 7 below, the Company shall announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (i) the release or waiver is effected solely to permit a transfer of securities that is not for consideration and (ii) the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

4. In the event of the liquidation of the Trust Account, the Sponsor (the “ Indemnitor ”) agrees 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 for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has entered into an acquisition agreement (a “ Target ”);  provided ,  however , that such indemnification of the Company by the Indemnitor shall apply only to the extent necessary to ensure that such claims by a third party for services rendered or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.10 per Offering Share or (ii) such lesser amount per Offering Share 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 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 of 1933, as amended. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Indemnitor shall not be responsible to the extent of any liability for such third party claim. The Indemnitor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense.

5. To the extent that the Underwriters do not exercise their over-allotment option in full to purchase an additional 1,500,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees that it shall forfeit, at no cost, a number of Founder Shares in the aggregate equal to 375,000 multiplied by a fraction, (i) the numerator of which is 1,500,000 minus the number of Units, if any, purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 1,500,000. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the stockholders prior to the Public Offering will own an aggregate of 20.0% of the Company’s issued and outstanding shares of Common Stock after the Public Offering (not including any Private Placement Shares). The Sponsor further agrees that to the extent that the size of the Public Offering is increased or decreased, the Company will purchase or sell shares of Common Stock or effect a stock dividend or share contribution back to capital, as applicable, immediately prior to the consummation of the Public Offering in such amount as to maintain the ownership of the stockholders prior to the Public Offering at 20.0% of its issued and outstanding shares of Common Stock upon the consummation of the Public Offering (not including any Private Placement Shares). In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 1,500,000 in the numerator and denominator of the formula in the first sentence of this paragraph shall be changed to a number equal to 15% of the number of shares included in the Units issued in the Public Offering and (B) the reference to 375,000 in the formula set forth in the first sentence of this paragraph shall be adjusted to such number of shares of the Common Stock that the Sponsor would have to return to the Company in order to hold (together with all of the pre-Public Offering stockholders) an aggregate of 20.0% of the Company’s issued and outstanding shares after the Public Offering (not including any Private Placement Shares).

6. Each officer of the Company agrees not to participate in the formation of, or become an officer or director of, any other blank check company until the Company has entered into a definitive agreement with respect to a Business Combination or the Company has failed to complete a Business Combination within the time period set forth in the Company’s amended and restated certificate of incorporation, as the same may be amended from time to time.

7. (a) Each Insider (if such Insider owns any Founder Shares) agrees that it, he or she shall not Transfer (as defined below) any Founder Shares until the earlier of (i) one year after the completion of a Business Combination or (ii) on such earlier date as provided in clauses (x) or (y) below if, subsequent to a Business Combination, (x) the last sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a Business Combination or (y) the date following the completion of a Business Combination on which the Company completes a liquidation, merger, stock exchange or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property (the “ Founder Shares Lock-up Period ”).

(b) The Sponsor agrees that it shall not effectuate any Transfer of Private Placement Shares, Private Placement Rights, Private Placement Warrants or Common Stock issued or issuable upon the exercise of the Private Placement Warrants or upon the conversion of the Private Placement Rights, until 30 days after the completion of a Business Combination (the “ Private Placement Lock-up Period ”, together with the Founder Shares Lock-up Period, the “ Lock-up Periods ”).

(c) Notwithstanding the provisions set forth in Sections 7(a) and (b), Transfers of the Founder Shares, Private Placement Shares, Private Placement Rights, Private Placement Warrants and shares of Common Stock issued or issuable upon the exercise of the Private Placement Warrants or upon the conversion of the Private Placement Rights are permitted to (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any members or partners of the Sponsor, or any affiliates of the Sponsor or any of its members or partners; (b) in the case of an individual, by gift to one of the members of the individual’s immediate family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, an affiliate of such person or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) 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) in the event of a Company liquidation prior to a completion of a Business Combination; (g) to the Company for no value for cancellation; or (h) by virtue of the laws of Delaware or either of the Sponsors’ operating agreements; provided, however, that in the case of clauses (a) through (f) and (h), these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions (including provisions relating to voting, the trust account and liquidation distributions described elsewhere in this letter or the Registration Statement). Any Transfer made in contravention of this Letter Agreement shall be null and void.

NOW, THEREFORE, in consideration of the premises and the mutual covenants hereinafter set forth and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and Subscriber hereby agree as follows:

1.      Agreement to Subscribe

1.1.       Purchase and Issuance of the Units.

1.2.       Purchase Price.

1.3.       Closings. The closing of the purchase and sale of the Initial Units shall take place simultaneously with the closing of the IPO and the closing of the purchase and sale of Additional Units shall take place simultaneously with the closing of the Over-Allotment Option (each a “ Closing Date ”).

1.4        Termination. This Agreement and each of the obligations of the undersigned shall be null and void and without effect if a Closing does not occur prior to June 30, 2017.

2.      Representations and Warranties of Subscriber

Subscriber represents and warrants to the Company that:

2.1.      No Government Recommendation or Approval.  Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement of the Company or the Offering of the Securities.

2.2.      Accredited Investor. Subscriber represents that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “ Securities Act ”), and acknowledges that the sale contemplated hereby is being made in reliance, among other things, on a private placement exemption to “accredited investors” under the Securities Act and similar exemptions under state law.

2.3.      Intent.  Subscriber is purchasing the Securities solely for investment purposes, for Subscriber’s own account (and/or for the account or benefit of its members or affiliates, as permitted, pursuant to the terms of an agreement (the “ Insider Letter ”) to be entered into with respect to the Securities between, among others, Subscriber  and the Company, as described in the Registration Statement), and not with a view to the distribution thereof and Subscriber has no present arrangement to sell the Securities to or through any person or entity except as may be permitted under the Insider Letter.  Subscriber shall not engage in hedging transactions with regard to the Securities unless in compliance with the Securities Act.

2.4.      Restrictions on Transfer.  Subscriber acknowledges and understands the Units are being offered in a transaction not involving a public offering in the United States within the meaning of the Securities Act.  The Securities have not been registered under the Securities Act and, if in the future Subscriber decides to offer, resell, pledge or otherwise transfer the Securities, such Securities may be offered, resold, pledged or otherwise transferred only (A) pursuant to an effective registration statement filed under the Securities Act, (B) pursuant to an exemption from registration under Rule 144 promulgated under the Securities Act, if available, or (C) pursuant to any other available exemption from the registration requirements of the Securities Act, and in each case in accordance with any applicable securities laws of any state or any other jurisdiction. Notwithstanding the foregoing, Subscriber acknowledges and understands the Securities are subject to transfer restrictions as described in Section 8 hereof. 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 with respect to such transfer. Absent registration or another available exemption from registration, Subscriber agrees it will not resell the Securities (unless otherwise permitted pursuant to the Insider Letter, as described in the Registration Statement).  Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be available to Subscriber for the resale of the Securities until the one year anniversary following consummation of the initial Business Combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions.

2.5.      Sophisticated Investor.

(i)  Subscriber is sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Securities.

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL FOR THIS CORPORATION, IS AVAILABLE.”

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO LOCKUP PURSUANT TO A THIRD AMENDED AND RESTATED UNIT PURCHASE AGREEMENT BY AND BETWEEN KBL MERGER CORP. IV AND THE PURCHASERS SET FORTH ON SCHEDULE A THERETO, AND MAY ONLY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP PURSUANT TO THE TERMS SET FORTH IN THE THIRD AMENDED AND RESTATED UNIT PURCHASE AGREEMENT.”

4.2.    Subscriber’s Compliance. Nothing in this Section 4 shall affect in any way Subscriber’s obligations and agreements to comply with all applicable securities laws upon resale of the Securities.

4.3.    Company’s Refusal to Register Transfer of the Securities.  The Company shall refuse to register any transfer of the Securities, if in the sole judgment of the Company such purported transfer would not be made (i) pursuant to an effective registration statement filed under the Securities Act, or pursuant to an available exemption from the registration requirements of the Securities Act and (ii) in compliance herewith.

4.4     Registration Rights. Subscriber will be entitled to certain registration rights which will be governed by a registration rights agreement (“ Registration Rights Agreement ”) to be entered into between, among others, Subscriber and the Company, on or prior to the effective date of the Registration Statement; provided, however, that the Subscriber may not exercise its demand and “piggy back” registration rights pursuant to such Registration Rights Agreement after five (5) and seven (7) years after the effective date of the Registration Statement, respectively, and the Subscriber may not exercise its demand registration rights thereunder more than one time.

5.     Lockup .

The Subscriber acknowledges and agrees that the Units, the Placement Shares, the Placement Warrants, the Placement Rights, the Warrant Shares and Rights Shares shall not be transferable, saleable or assignable until 30 days after the consummation of a Business Combination, except to permitted transferees. The Units, the Placement Shares, the Placement Warrants, the Placement Rights, the Warrant Shares and the Rights Shares will be deemed compensation by the Financial Industry Regulatory Authority (“FINRA”) and will therefore be subject to lock-up for a period of 180 days immediately following the date of effectiveness of the Registration Statement or commencement of sales of the IPO, subject to certain limited exceptions, pursuant to Rule 5110(g)(1) of the FINRA Manual. Accordingly, the Units, the Placement Shares, the Placement Warrants, the Placement Rights, the Warrant Shares and the Rights Shares may not be sold, transferred, assigned, pledged or hypothecated for 180 days immediately following the effective date of the Registration Statement except to any underwriter or selected dealer participating in the IPO and the bona fide officers or partners of the Subscriber and any such participating underwriter or selected dealer nor may they be the subject of any hedging, short sale, derivative, put or call transaction that would result in the economic disposition of the securities by any person during such 180-day period.

6.     Waiver of Liquidation Distributions.

In connection with the Securities purchased pursuant to this Agreement, Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions of the amounts in the Trust Account with respect to the Securities, whether (i) in connection with the exercise of redemption rights if the Company consummates the Business Combination, (ii) in connection with any tender offer conducted by the Company prior to a Business Combination or (iii) upon the Company’s redemption of shares of Common Stock sold in the Company’s IPO upon the Company’s failure to timely complete the Business Combination.  In the event Subscriber purchases shares of Common Stock in the IPO or in the aftermarket, any additional shares so purchased shall be eligible to receive the redemption value of such shares of Common Stock upon the same terms offered to all other purchasers of Common Stock in the IPO in the event the Company fails to consummate the Business Combination.

7.     Termination of Placement Warrants and Placement Rights .

7.1.    Failure to Consummate Business Combination. The Placement Warrants and Placement Rights shall be terminated upon the dissolution of the Company or in the event that the Company does not consummate the Business Combination within 18 months from the consummation of the IPO, or 21 months from the consummation of the IPO if the Company has an executed letter of intent, agreement in principle or definitive agreement for an initial business combination within 18 months from the closing of the IPO, but has not completed the initial business combination within such 18-month period, or unless otherwise extended by the Company.

7.2.    Termination of Rights as Holder. If the Placement Warrants and Placement Rights are terminated in accordance with Section 7.1, then after such time Subscriber (or successor in interest) shall no longer have any rights as a holder of such Placement Warrants and Placement Rights and the Company shall take such action as is appropriate to cancel such Placement Warrants and Placement Rights. Subscriber hereby irrevocably grants the Company a limited power of attorney for the purpose of effectuating the foregoing and agrees to take any and all measures reasonably requested by the Company necessary to effect the foregoing.

8.     Rescission Right Waiver and Indemnification .

8.1.    Subscriber understands and acknowledges an exemption from the registration requirements of the Securities Act requires there be no general solicitation of purchasers of the Units. In this regard, if the IPO were deemed to be a general solicitation with respect to the Units, the offer and sale of such Units may not be exempt from registration and, if not, Subscriber may have a right to rescind its purchase of the Units. In order to facilitate the completion of the Offering and in order to protect the Company, its stockholders and the amounts in the Trust Account from claims that may adversely affect the Company or the interests of its stockholders, Subscriber hereby agrees to waive, to the maximum extent permitted by applicable law, any claims, right to sue or rights in law or arbitration, as the case may be, to seek rescission of its purchase of the Units. Subscriber acknowledges and agrees this waiver is being made in order to induce the Company to sell the Units to the Subscriber. Subscriber agrees the foregoing waiver of rescission rights shall apply to any and all known or unknown actions, causes of action, suits, claims or proceedings (collectively, “ Claims ”) and related losses, costs, penalties, fees, liabilities and damages, whether compensatory, consequential or exemplary, and expenses in connection therewith, including reasonable attorneys’ and expert witness fees and disbursements and all other expenses reasonably incurred in investigating, preparing or defending against any Claims, whether pending or threatened, in connection with any present or future actual or asserted right to rescind the purchase of the Units hereunder or relating to the purchase of the Units and the transactions contemplated hereby.

8.2.   Subscriber agrees not to seek recourse against the Trust Account for any reason whatsoever in connection with its purchase of the Units or any Claim that may arise now or in the future relating to the purchase of the Units.

8.3.    Subscriber acknowledges and agrees that the stockholders of the Company are and shall be third-party beneficiaries of this Section 8. 

8.4.    Subscriber agrees that to the extent any waiver of rights under this Section 8 is ineffective as a matter of law, Subscriber has offered such waiver for the benefit of the Company as an equitable right that shall survive any statutory disqualification or bar that applies to a legal right. Subscriber acknowledges the receipt and sufficiency of consideration received from the Company hereunder in this regard.

9.     Terms of the Units and Underlying Securities

9.1. The Units and their component parts are substantially identical to the units to be offered in the IPO except that: (i) the Units and component parts will be subject to transfer restrictions, except in limited circumstances, until 30 days following the consummation of the Business Combination, (ii) the Placement Warrants will be non-redeemable so long as they are held by the initial holder thereof (or any of its permitted transferees), and may be exercisable on a “cashless” basis if held by Subscriber or its permitted transferees and (iii) the Units and component parts are being purchased pursuant to an exemption from the registration requirements of the Securities Act and will become freely tradable only after the expiration of the lockup described above in clause (i) and they are registered pursuant to the Registration Rights Agreement to be signed on or before the date of the Prospectus or an exemption from registration is available. Additionally, so long as the Placement Warrants are held by the Subscriber or its designees, they will not be permitted to exercise such Placement Warrants after the five year anniversary of the effective date of the Registration Statement.
