    Re:
      Initial Public Offering

    


    Gentlemen:

    


    The
      undersigned officer and director of Fortissimo Acquisition Corp. (“Company”), in
      consideration of EarlyBirdCapital, Inc. (“EBC”) entering into a letter of intent
      (“Letter of Intent”) to underwrite an initial public offering of the securities
      of the Company (“IPO”) and embarking on the IPO process, hereby agrees as
      follows (certain capitalized terms used herein are defined in paragraph 10
      hereof): 

    


    
      	 	
              1.

            	
              In
                the event that the Company fails to consummate a Business Combination
                within 18 months from the effective date (“Effective Date”) of the
                registration statement relating to the IPO (or 24 months under the
                circumstances described in the prospectus relating to the IPO), the
                undersigned will (i) cause the Trust Fund (as defined in the Letter
                of
                Intent) to be liquidated and distributed to the holders of IPO Shares
                and
                (ii) take all reasonable actions within his power to cause the Company
                to
                liquidate as soon as reasonably practicable. The undersigned hereby
                waives
                any and all right, title, interest or claim of any kind in or to
                any
                distribution of the Trust Fund and any remaining net assets of the
                Company
                as a result of such liquidation with respect to his Insider Shares
                (“Claim”) and hereby waives any Claim the undersigned 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. In the event of the liquidation of the Trust Fund,
                the
                undersigned agrees to indemnify and hold harmless the Company, severally
                pro rata with Eli Blatt, Yuval Cohen, Shmoulik Barashi and Yochai
                Hacohen
                based on the number of Insider Shares beneficially owned by each
                such
                individual, against any and all loss, liability, claims, 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) which the Company may become subject as a result
                of any
                claim by any vendor or other person who is owed money by the Company
                for
                services rendered or products sold or contracted for, or by any target
                business, but only to the extent necessary to ensure that such loss,
                liability, claim, damage or expense does not reduce the amount in
                the
                Trust Fund. 

            


    

    
      	 	
              2.

            	
              In
                order to minimize potential conflicts of interest which may arise
                from
                multiple affiliations, the undersigned agrees to present to the Company
                for its consideration, prior to presentation to any other person
                or
                entity, any suitable opportunity to acquire an operating business,
                until
                the earlier of the consummation by the Company of a Business Combination,
                the liquidation of the Company or until such time as the undersigned
                ceases to be an officer or director of the Company, subject to any
                pre-existing fiduciary and contractual obligations the undersigned
                might
                have.

            


    

    
      	 	
              3.

            	
              The
                undersigned acknowledges and agrees that the Company will not consummate
                any Business Combination which involves a company which is affiliated
                with
                any of the Insiders unless the Company obtains an opinion from an
                independent investment banking firm reasonably acceptable to EBC
                that the
                business combination is fair to the Company’s stockholders from a
                financial perspective.

            


    

    
      	 	
              4.

            	
              Neither
                the undersigned, any member of the family of the undersigned, nor
                any
                affiliate (“Affiliate”) of the undersigned will be entitled to receive and
                will not accept any compensation for services rendered to the Company
                prior to or in connection with the consummation of the Business
                Combination; provided that commencing on the Effective Date, Fortissimo
                Capital Management Ltd. ("Related Party"), shall be allowed to charge
                the
                Company $7,500 per month, representing an allocable share of Related
                Party's overhead, to compensate it for the Company's use of Related
                Party's offices, utilities and personnel. Related Party and the
                undersigned shall also be entitled to reimbursement from the Company
                for
                their out-of-pocket expenses incurred in connection with seeking
                and
                consummating a Business
                Combination.

                is unable to act as such, the undersigned will promptly notify the
                Company
                and EBC and appoint a substitute agent acceptable to each of the

                and EBC within 30 days and nothing in this letter will affect the
                right of
                either party to serve process in any other manner permitted by
                law.

            


    

    
      	 	
              10.

            	
              As
                used herein, (i) a “Business Combination” shall mean an acquisition by
                merger, capital stock exchange, asset or stock acquisition, reorganization
                or otherwise, of an operating business; (ii) “Insiders” shall mean all
                officers, directors and stockholders of the Company immediately prior
                to
