6.10 Release from Guaranties. Each of Borrower and Lender agree that, upon the completion of the IPO resulting in the receipt by the Borrower of gross proceeds equal to or greater than $60,000,000, Lender shall release each of the Borrower’s respective Subsidiaries from any guarantee obligations and shall amend the Stock Pledge Agreement so that the stock of the Subsidiary pledged by Borrower as security is equal to 65% of all outstanding equity of each of the Subsidiaries; provided, however, that, upon the occurrence of an Event of Default, Borrower shall cause each of the Subsidiaries with securities subject to the Stock Pledge Agreement to execute and deliver to the Lender a guaranty and security agreement in the same form as previously executed.

7.10 Maintenance of Subsidiaries. Borrower shall not, and shall not permit or cause any Subsidiary to, (i) sell, dispose of, convey, or allow a Lien, other than Permitted Liens, to arise on any of its assets, including Intellectual Property owned by such Subsidiary (and for this purpose, the definition of “Intellectual Property” shall be deemed to refer to such Subsidiary) except for non-exclusive licenses entered into in the ordinary course of business; (ii) divest or “spin-off” any Subsidiary except where as a result of such transaction Borrower and/or Borrower’s shareholders or affiliates retain or obtain majority ownership of such Subsidiary; (iii) merge or consolidate any Subsidiary with or into another entity (unless as a result of such merger Borrower and/or Borrower’s shareholders or affiliates retain or obtain majority ownership of the surviving entity); (iv) permit a Change of Control (as defined below) of any Subsidiary; (v) permit a Lien other than Permitted Liens, (and for this purpose, the definitions of “Lien” and

“Permitted Liens” shall be deemed to refer to such Subsidiary), to arise on, or make a pledge of, any capital stock of any Subsidiary in favor of any person other than Lender; or (vi) materially change the corporate structure and business operations of the Borrower and its Subsidiaries taken as a whole. For the purposes of this Section 7.10, a “Change of Control” shall mean, any transaction or series of related transactions whereby the Borrower and/or Borrower’s shareholders or affiliates of Borrower holding in excess of 50% of the outstanding voting capital stock of any Subsidiary immediately prior to such transaction or transactions, shall own less than 50% of the outstanding voting or capital stock of such Subsidiary immediately following such transaction or transactions. Notwithstanding the foregoing, (a) the existing financing arrangement between MBI Israel and Bank Leumi; (b) the existing financing arrangements between Integrity and Bank Leumi and Discount Bank; (c) the Indebtedness owed to the former shareholders of GlassHouse Technologies AG, in an amount not to exceed CHF 415,000 and the Indebtedness owed to the former shareholders of Systems Group Integration, Ltd. In an amount not to exceed £72,000; and (d) the amounts advanced to GlassHouse Technologies AG under a receivables factoring agreement with Credit Suisse, in an amount not to exceed CHF 500,000, shall be deemed “Permitted Indebtedness” and “Permitted Liens” hereunder, provided, however, Borrower shall not cause either MBI Israel or Integrity to grant additional Liens to either Bank Leumi, Discount Bank or any other entity.

Except as amended hereby, the Loan and Security Agreement remains unmodified and unchanged.
