Merger Corp.

Gentlemen:

 

This
letter agreement amends and restates the letter agreement (the “Original Agreement”) dated November 21, 2014 among
Harmony Merger Corp. (the “Corporation”), the undersigned and Graubard Miller (“GM”), counsel to the Corporation,
in its entirety and the Original Agreement shall be deemed to have been superseded and replaced in their entirety by this letter
agreement.

 

The
Corporation, a blank check company formed for the purpose of acquiring one or more businesses or entities (a “Business Combination”),
intends to register its securities under the Securities Act of 1933, as amended (“Securities Act”), in connection
with its initial public offering (“IPO”).

 

The
undersigned previously purchased an aggregate of 135,000 shares (“Insider Shares”) of common stock of the Corporation,
par value $.0001 per share (“Common Stock”), of the Corporation for an aggregate purchase price of $1,258.67. In addition,
the undersigned acknowledges and agrees that if the underwriters in the IPO determine the size of the offering should be increased
or decreased, the undersigned will either receive a dividend on its Insider Shares or contribute a portion of the Insider Shares
back to capital, as applicable, in order to maintain the aggregate ownership of the Corporation’s initial stockholders at
a certain percentage of the number of shares to be sold in the IPO. Any decrease in the size of the offering will affect all holders
of Insider Shares on a pro-rata basis, except to the extent necessary to maintain the undersigned’s ratio of two (2) Insider
Shares for every one (1) Insider Unit purchased. Any increase in the size of the offering will affect all of the holders of Insider
Shares on a pro-rata basis, such that any share dividend may result in the undersigned receiving more than two Insider Shares
for every one Insider Unit purchased.

 

The
undersigned commits to purchase an aggregate of 67,500 units of the Corporation (“Insider Units”), each Insider Unit
consisting of one share of Common Stock and one warrant (“Warrant”) to purchase, in the five years following a Business
Combination, three-fourths (3/4) of one share of Common Stock for $11.50 per whole share, for an aggregate purchase price of $675,000
(the “Initial Purchase Price”). Pursuant to the Original Agreement, the undersigned has caused the Initial Purchase
Price to be delivered to GM, to hold in an interest bearing account until the Corporation consummates the IPO and over-allotment
option, if any, together with an originally executed Form W-9, W-8BEN or W-81MY, as applicable. However, if the underwriters in
the IPO exercise their over-allotment option in full or part, the undersigned commits to sell back to Eric Rosenfeld up to 20,000
Insider Shares (“Over-allotment Sale”). Such Over-allotment Sale shall be structured such that the undersigned maintains
its ratio of two (2) Insider Shares for every one (1) Insider Unit purchased. Therefore, up to $100,000 of the Initial Purchase
Price will be returned to the undersigned in the event that the over-allotment is exercised. If the underwriter determines that
fewer Insider Units must be purchased in order to consummate the IPO based on market conditions at that time, such reduction in
Insider Unit purchases shall be done on a pro-rata basis, which may result in the undersigned receiving more than two Insider
Shares for every one Insider Unit purchased.

 

    	 

    	 

    

 

The
consummation of the purchase and issuance of the Insider Units shall occur simultaneously with the consummation of the IPO. Simultaneously
with the consummation of the IPO, GM shall (i) deposit the Initial Purchase Price, without interest or deduction, into the trust
fund (“Trust Fund”) established by the Corporation for the benefit of the Corporation’s public stockholders
as described in the Corporation’s registration statement filed in connection with the IPO (“Registration Statement”)
and (ii) deliver all interest earned on the Initial Purchase Price to the undersigned. If the Corporation does not complete the
IPO on or before December 23, 2014 (subject to a six (6) month extension at the Corporation’s option in its sole discretion),
the Purchase Price (plus interest earned thereon) will be returned to the undersigned.

 

Each
of the Corporation and the undersigned acknowledges and agrees that GM is serving hereunder solely as a convenience to the parties
to facilitate the purchase of the Insider Units and GM’s sole obligation under this letter agreement is to act with respect
to holding and disbursing the Purchase Price for the Insider Units as described above. GM shall not be liable to the Corporation
or the undersigned or any other person or entity in respect of any act or failure to act hereunder or otherwise in connection
with performing its services hereunder unless GM has acted in a manner constituting gross negligence or willful misconduct. The
Corporation shall indemnify GM against any claim made against it (including reasonable attorney’s fees) by reason of it
acting or failing to act in connection with this letter agreement except as a result of its gross negligence or willful misconduct.
GM may rely and shall be protected in acting or refraining from acting upon any written notice, instruction or request furnished
to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties. Notwithstanding
anything to the contrary contained herein, GM agrees that it does not have any right, title, interest or claim of any kind in
or to any monies of the Trust Fund (“Claim”) and hereby waives any Claim it may have in the future as a result of,
or arising out of, any services provided to the Company and will not seek recourse against the Trust Fund for any reason whatsoever.

 

The
Corporation has not entered into, and will not enter into, without the prior consent of 2/3 in value of the Insider Units held
by the Sponsor Group (defined below), prior to the consummation of a Business Combination, any letter or similar agreement with
any other investor or prospective investor in the Corporation (each, a “New Investor”) that has the direct or indirect
effect of establishing terms, rights, or benefits for such New Investor (or any affiliate or associate thereof) in a manner more
favorable to such New Investor than the terms, rights, and benefits established in favor of the undersigned (a “More Favorable
Arrangement”). If the Corporation receives approval from the Sponsor Group as described in the immediately preceding sentence,
it will offer the undersigned and the other members of the Sponsor Group the right to assume all, or participate in part, of the
obligations pursuant to such More Favorable Arrangement, pro rata with the other members of the Sponsor Group, on the same terms
as it offers such New Investor. If the undersigned does not indicate its intention to assume all, or participate in part, of the
obligations of such More Favorable Arrangement within three business days, the Corporation shall be free to offer such More Favorable
Arrangement to any New Investor it wishes.

 

The
Corporation shall not, without the prior written consent of the undersigned, use in any advertising, publicity, marketing materials,
other similar communication to third parties, or in any other public use, as such, the names, brands or trademarks of the undersigned
or any of its affiliates, officers, directors and employees, provided that the name of the holder of Insider Shares and Insider
Units may be used in any prospectus or other regulatory filing in connection with the IPO.

The
Insider Shares will be identical to the shares of Common Stock included in the units to be sold by the Corporation in the IPO,
and the Insider Units will be identical to the units to be sold by the Corporation in the IPO, except that:

 

		●	up
                                         to 20,000 of the Insider Shares must be sold back to Eric Rosenfeld if the underwriters
                                         exercise their over-allotment option in the IPO, except that in the event the sale would
                                         result in a reduction in the undersigned’s ratio of Insider Shares to Insider Units,
                                         in which case a lesser number of Insider Shares will be subject to sale;
	 	 	 
		●	the
                                         undersigned agrees to vote the Insider Shares and shares of Common Stock included in
                                         the Insider Units in favor of any proposed Business Combination;
	 	 	 
		●	all
                                         Insider Shares (including those held by other Holders (as defined below) will be placed
                                         in escrow, subject to the terms of an escrow agreement reasonably acceptable to the undersigned,
                                         and will not be released (subject to certain exceptions) until (A) the earlier of one
                                         year after the completion of a Business Combination and the date on which the closing
                                         price of the Common Stock exceeds $12.50 for any 20 trading days within a 30-trading
                                         day period following the completion of a Business Combination with respect to 50% of
                                         the Insider Shares and (B) one year after the completion of a Business Combination with
                                         respect to the remaining 50% of the Insider Shares, and may only be transferred during
                                         this time period (i) amongst the initial purchasers of the Insider Shares, to the Corporation’s
                                         officers, directors and employees, to a holder’s affiliates, or to its members
                                         upon its liquidation, (ii) to relatives and trusts for estate planning purposes, (iii)

                                         were originally purchased or (vi) to the Corporation for cancellation in connection with
                                         the consummation of a Business Combination, in each case (except for clause (vi)) where
                                         the transferee agrees to the terms of the escrow agreement and the voting requirements
                                         set forth above);

                                         Insider Shares and Insider Units will be subject to customary registration rights, which

                                         or in the open market) if the Corporation fails to consummate a Business Combination;

		●	the
                                         Insider Shares and Insider Units will include any additional terms or restrictions as
                                         is customary in other similarly structured blank check company offerings or as may be
                                         reasonably required by the underwriters in the IPO in order to consummate the IPO, each
                                         of which will be set forth in the Registration Statement.

 

The
Company also agrees that so long as the Warrants included in the Private Units continue to be held by the undersigned or its permitted
transferees, the Company will not redeem such Warrants and will permit the undersigned or its permitted transferees to exercise
such Warrants on a cashless basis by surrendering such Warrants for that number of shares of Common Stock equal to the quotient
obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference
between the exercise price of the Warrants and the “Fair Market Value” by (y) the Fair Market Value; provided, however,
that no cashless exercise shall be permitted unless the Fair Market Value is higher than the exercise price. Solely for purposes
of this agreement, the “Fair Market Value” shall mean the average reported last sale price of the Common Stock for
the 10 trading days ending on the day prior to the Company’s receipt of the applicable exercise notice. Additionally, because
the Warrants included in the Private Units are being issued in a private transaction, they may be exercisable by the undersigned
or its permitted transferees for unregistered ordinary shares even if the prospectus relating to the ordinary shares issuable
upon exercise of the Warrants is not current and effective.

 

Each
of the undersigned and the Corporation acknowledges and agrees that, in order to consummate any Business Combination, the holders
of Insider Shares or Insider Units (“Holders”) may be required to contribute back to the capital of the Corporation
a portion of any such securities for cancellation and that such contributions will occur as follows:

 

		●	first, all Holders other than DKU 2013 LLC, The K2 Principal Fund L.P., NPIC Limited, Covalent Capital Partners Master Fund, L.P.,
Jeff Hastings, and Leonard Schlemm (collectively, the “Sponsor Group”), until all Holders have the same ratio of Insider
Shares to Insider Units; and
	 	 	 
		●	second, all Holders including the members of the Sponsor Group, pro rata based on the number of Insider Shares or Insider Units,
as applicable, held by each Holder after giving effect to (i) above, such that in all cases the ratio of Insider Shares to Insider
Units is equal.

 

    	4

    	 

    

 

Notwithstanding
anything to the contrary contained herein, the undersigned’s liability arising out of or related to this letter agreement
shall not exceed the Initial Purchase Price.

 

The
undersigned acknowledges and agrees that it will execute agreements in form and substance typical for transactions of this nature
necessary to effectuate the foregoing agreements and obligations prior to the consummation of the IPO as are reasonably acceptable
to the undersigned, including but not limited to (i) an insider letter, (ii) an escrow agreement and (iii) a registration rights
agreement.

 

The
undersigned hereby represents and warrants that, as applicable:

 

		(a)	it
                                         has been advised that the Insider Shares and Insider Units have not been registered under

Harmony
Merger Corp.

777 Third
Avenue, 37th Floor

New York,
New York 10017

 

Gentlemen:

 

This
letter agreement amends and restates the letter agreement (the “Original Agreement”) dated November 20, 2014 among
Harmony Merger Corp. (the “Corporation”), the undersigned and Graubard Miller (“GM”), counsel to the Corporation,
in its entirety and the Original Agreement shall be deemed to have been superseded and replaced in their entirety by this letter
agreement.

 

The
Corporation, a blank check company formed for the purpose of acquiring one or more businesses or entities (a “Business Combination”),
intends to register its securities under the Securities Act of 1933, as amended (“Securities Act”), in connection
with its initial public offering (“IPO”).

 

The
undersigned previously purchased an aggregate of 100,000 shares (“Insider Shares”) of common stock of the Corporation,
par value $.0001 per share (“Common Stock”), of the Corporation for an aggregate purchase price of $945.63. The undersigned
acknowledges and agrees that if the underwriters in the IPO determine the size of the offering should be increased or decreased,
the undersigned will either receive a dividend on its Insider Shares or contribute a portion of the Insider Shares back to capital,
as applicable, in order to maintain the aggregate ownership of the Corporation’s initial stockholders at a certain percentage
of the number of shares to be sold in the IPO. Any decrease in the size of the offering will affect all holders of Insider Shares
on a pro-rata basis, except to the extent necessary to maintain the undersigned’s ratio of two (2) Insider Shares for every
one (1) Insider Unit purchased. Any increase in the size of the offering will affect all of the holders of Insider Shares on a
pro-rata basis, such that any share dividend may result in the undersigned receiving more than two Insider Shares for every one
Insider Unit purchased.

 

The
undersigned commits to purchase an aggregate of 50,000 units of the Corporation (“Insider Units”), each Insider Unit
consisting of one share of Common Stock and one warrant (“Warrant”) to purchase, in the five years following a Business
Combination, three-fourths (3/4) of one share of Common Stock for $11.50 per whole share, for an aggregate purchase price of $500,000
(the “Initial Purchase Price”). Pursuant to the Original Agreement, the undersigned has caused the Initial Purchase
Price to be delivered to GM, to hold in an interest bearing account until the Corporation consummates the IPO and over-allotment
option, if any, together with an originally executed Form W-9, W-8BEN or W-81MY, as applicable.

 

The
consummation of the purchase and issuance of the Insider Units shall occur simultaneously with the consummation of the IPO. Simultaneously
with the consummation of the IPO, GM shall (i) deposit the Initial Purchase Price, without interest or deduction, into the trust
fund (“Trust Fund”) established by the Corporation for the benefit of the Corporation’s public stockholders
as described in the Corporation’s registration statement filed in connection with the IPO (“Registration Statement”)
and (ii) deliver all interest earned on the Initial Purchase Price to the undersigned. If the Corporation does not complete the
IPO on or before December 23, 2014 (subject to a six (6) month extension at the Corporation’s option in its sole discretion),
the Initial Purchase Price (plus interest earned thereon) will be returned to the undersigned.

 

    	 

    	 

    

 

Each
of the Corporation and the undersigned acknowledges and agrees that GM is serving hereunder solely as a convenience to the parties
to facilitate the purchase of the Insider Units and GM’s sole obligation under this letter agreement is to act with respect
to holding and disbursing the Initial Purchase Price for the Insider Units as described above. GM shall not be liable to the Corporation
or the undersigned or any other person or entity in respect of any act or failure to act hereunder or otherwise in connection
with performing its services hereunder unless GM has acted in a manner constituting gross negligence or willful misconduct. The
Corporation shall indemnify GM against any claim made against it (including reasonable attorney’s fees) by reason of it
acting or failing to act in connection with this letter agreement except as a result of its gross negligence or willful misconduct.
GM may rely and shall be protected in acting or refraining from acting upon any written notice, instruction or request furnished
to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties. Notwithstanding
anything to the contrary contained herein, GM agrees that it does not have any right, title, interest or claim of any kind in
or to any monies of the Trust Fund (“Claim”) and hereby waives any Claim it may have in the future as a result of,
or arising out of, any services provided to the Company and will not seek recourse against the Trust Fund for any reason whatsoever.

 

The
Corporation has not entered into, and will not enter into, without the prior consent of 2/3 in value of the Insider Units held
by the Sponsor Group (defined below), prior to the consummation of a Business Combination, any letter or similar agreement with
any other investor or prospective investor in the Corporation (each, a “New Investor”) that has the direct or indirect
effect of establishing terms, rights, or benefits for such New Investor (or any affiliate or associate thereof) in a manner more
favorable to such New Investor than the terms, rights, and benefits established in favor of the undersigned (a “More Favorable
Arrangement”). If the Corporation receives approval from the Sponsor Group as described in the immediately preceding sentence,
it will offer the undersigned and the other members of the Sponsor Group the right to assume all, or participate in part, of the
obligations pursuant to such More Favorable Arrangement, pro rata with the other members of the Sponsor Group, on the same terms
as it offers such New Investor. If the undersigned does not indicate its intention to assume all, or participate in part, of the
obligations of such More Favorable Arrangement within three business days, the Corporation shall be free to offer such More Favorable

In
accordance with the guidelines of Rule 10b5-1 of the Securities Exchange Act, Eric Rosenfeld (“Rosenfeld”) shall place
limit orders for an aggregate of no less than $500,000 of the Corporation’s common stock (the “Market-Purchased Shares”)
commencing on the later of (1) two business days after the Corporation files a Form 8-K disclosing all material information relating
to its initial Business Combination, and (2) 60 days after the termination of the “restricted period” in connection
with the Corporation’s Initial Public Offering under Regulation M of the Securities Exchange Act, and ending on the record
date for the shareholder meeting at which such initial Business Combination is to be approved (“Buyback Period”).
These limit orders will require Mr. Rosenfeld to purchase any of the Corporation’s shares of common stock offered for sale
(and not purchased by another investor) at or below a price equal to the per-share amount held in the Trust Fund as reported in
such Form 8-K, until the earlier of (1) the expiration of the Buyback Period or (2) the date such purchases reach $500,000 in
total. The Corporation commits that the Buyback Period that begins as a result of the occurrence of the event described in (1)
above, shall be not less than twenty (20) business days. It is intended that the purchases will satisfy the conditions of Rule
10b-18(b) under the Securities Exchange Act and the broker’s purchase obligation will otherwise be subject to applicable
law, including Regulation M under the Securities Exchange Act, which may prohibit or limit purchases pursuant to the limit order
agreement in certain circumstances.

 

Rosenfeld
agrees that the Market-Purchased Shares shall not be transferable until (A) the earlier of one year after the completion of a
Business Combination and the date on which the closing price of the Common Stock exceeds $12.50 for any 20 trading days within
a 30-trading day period following the completion of a Business Combination with respect to 50% of the Market-Purchased Shares
and (B) one year after the completion of a Business Combination with respect to the remaining 50% of the Market-Purchased Shares,
and may only be transferred during this time period (i) amongst the initial purchasers of the Insider Shares, to the Corporation’s
officers, directors and employees, to a holder’s affiliates, or to its members upon its liquidation, (ii) to relatives and
trusts for estate planning purposes, (iii) by virtue of the laws of descent and distribution upon death or (iv) pursuant to a
qualified domestic relations order, in each case where the transferee agrees to foregoing transfer restrictions. Rosenfeld shall
not convert the Market-Purchased Shares for cash held in the Corporation’s trust account in connection with any Business
Combination. Notwithstanding anything to the contrary contained herein, if the Corporation is unable to consummate a Business
Combination, Rosenfeld shall be entitled to liquidation proceeds with respect to the Market-Purchased Shares.

 

The
Insider Shares will be identical to the shares of Common Stock included in the units to be sold by the Corporation in the IPO,
and the Insider Units will be identical to the units to be sold by the Corporation in the IPO, except that:

                                         and will not be released (subject to certain exceptions) until (A) the earlier of one
                                         year after the completion of a Business Combination and the date on which the closing
                                         price of the Common Stock exceeds $12.50 for any 20 trading days within a 30-trading
                                         day period following the completion of a Business Combination with respect to 50% of

                                         respect to the remaining 50% of the Insider Shares, and may only be transferred during

                                         restrictions) until after the completion of a Business Combination;

 

		●	the
                                         Insider Shares and Insider Units will be subject to customary registration rights, which
                                         shall be described in the Registration Statement;

 

		●	the

                                         respect to any units or shares of Common Stock purchased by the undersigned in the IPO
                                         or in the open market) if the Corporation fails to consummate a Business Combination;
                                         and

 

		●	the
                                         Insider Shares and Insider Units will include any additional terms or restrictions as
                                         is customary in other similarly structured blank check company offerings or as may be
                                         reasonably required by the underwriters in the IPO in order to consummate the IPO, each
                                         of which will be set forth in the Registration Statement.

 

The
Company also agrees that so long as the Warrants included in the Private Units continue to be held by the undersigned or its permitted
transferees, the Company will not redeem such Warrants and will permit the undersigned or its permitted transferees to exercise
such Warrants on a cashless basis by surrendering such Warrants for that number of shares of Common Stock equal to the quotient
obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference
between the exercise price of the Warrants and the “Fair Market Value” by (y) the Fair Market Value; provided, however,
that no cashless exercise shall be permitted unless the Fair Market Value is higher than the exercise price. Solely for purposes
of this agreement, the “Fair Market Value” shall mean the average reported last sale price of the Common Stock for
the 10 trading days ending on the day prior to the Company’s receipt of the applicable exercise notice. Additionally, because
the Warrants included in the Private Units are being issued in a private transaction, they may be exercisable by the undersigned
or its permitted transferees for unregistered ordinary shares even if the prospectus relating to the ordinary shares issuable
upon exercise of the Warrants is not current and effective.

Each
of the undersigned and the Corporation acknowledges and agrees that, in order to consummate any Business Combination, the holders
of Insider Shares or Insider Units (“Holders”) may be required to contribute back to the capital of the Corporation
a portion of any such securities for cancellation and that such contributions will occur as follows:

 

		●	first,

                                         Capital Partners Master Fund, L.P., Jeff Hastings, and Leonard Schlemm (collectively,
                                         the “Sponsor Group”), until all Holders have the same ratio of Insider Shares
                                         to Insider Units; and

 

		●	second,
                                         all Holders including the members of the Sponsor Group, pro rata based on the number
                                         of Insider Shares or Insider Units, as applicable, held by each Holder after giving effect
                                         to (i) above, such that in all cases the ratio of Insider Shares to Insider Units is
                                         equal.

 

Notwithstanding
anything to the contrary contained herein, the undersigned’s liability arising out of or related to this letter agreement
shall not exceed the Initial Purchase Price.

necessary to effectuate the foregoing agreements and obligations prior to the consummation of the IPO as are reasonably acceptable
