As a condition to the closing of the Merger, all of the holders of shares of ISPSoft’s capital stock, including Signal Lake, were required to enter into lock-up agreements. Pursuant to the lock-up agreement executed by Signal Lake (the "Lock-Up Agreement"), Signal Lake agreed, with respect to the shares of Common Stock owned by it as a result of the transactions contemplated by the Merger Agreement, not to sell, transfer, pledge or otherwise dispose of, or reduce an interest in or risk relating to such shares in accordance with the percentages set forth below: 20% of such shares shall be subject to lock-up for a period of 60 days subsequent to the date of closing of the Merger, subject to customary exceptions; 20% of such shares shall be subject to lock-up for a period of 90 days subsequent to the date of closing of the Merger, subject to customary exceptions; 20% of such shares shall be subject to lock-up for a period of 120 days subsequent to the date of closing of the Merger, subject to customary exceptions; 20% of such shares shall be subject to lock-up for a period of 150 days subsequent to the date of closing of the Merger, subject to customary exceptions; and 20% of such shares shall be subject to lock-up for a period of 180 days subsequent to the date of closing of the Merger, subject to customary exceptions. The description of the Lock-Up Agreement contained in this Item 6 is qualified in its entirety by reference to the full text of such agreement, which is incorporated herein by reference.

The Issuer has deposited in escrow, with Commerce Bank, as escrow agent (the "Escrow Agent"), pursuant to the terms of an escrow agreement by and among the Issuer, Binay Sugla and Commerce Bank (the "Escrow Agreement"), certificates representing ten percent of the shares of Common Stock issued in the Merger to the holders of ISPSoft capital stock for the purpose of securing the indemnification obligations of the ISPSoft shareholders pursuant to the Merger Agreement. A total of 34,531 shares of Common Stock issuable to Signal Lake are currently held pursuant to the terms of the Escrow Agreement. Mr. Binay Sugla will serve as the indemnification representative on behalf of such ISPSoft shareholders. The escrow shares are required to be issued in the name of the Escrow Agent or its nominee and may not be transferred or assigned while held in escrow, other than by operation of law. In the event the Issuer distributes any securities in respect to, or in exchange for, the shares of Common Stock held in escrow by way of a stock dividend, stock split or otherwise, such securities shall be issued in the name of the Escrow Agent or its nominee and delivered to the Escrow Agent, who shall hold such shares in escrow. In the event the Issuer distributes cash dividends or property other than securities, in respect to the shares of Common Stock held in escrow, such cash or property shall be promptly distributed by the Escrow Agent to those for whom the shares of Common Stock are being held in escrow. Under the Escrow Agreement, the escrow shares will be voted by the Escrow Agent on behalf of the ISPSoft shareholders in accordance with instructions received by the Escrow Agent from the indemnification representative. In the absence of these instructions, the Escrow Agent will not vote the shares held in escrow. The Escrow Agent shall distribute the Common Shares held in escrow (1) in accordance with a written instrument signed by the Issuer and the indemnification representative or (2) in accordance with the written directive of a court. In the event neither of the preceding occurs, the Escrow Agent shall distribute all of the shares in escrow to the persons in whose names the shares are registered after the passage of 12 months following the closing of the Merger. If the Issuer asserts an indemnification claim, some (but no more than fifty percent) of the shares held in escrow, which amount shall be determined in accordance with the terms of the escrow agreement, will remain in escrow and be distributed upon resolution of the indemnification claim. The description of the Escrow Agreement contained in this Item 6 is qualified in its entirety by reference to the full text of such agreement, which is incorporated herein by reference.

Pursuant to the Merger Agreement, Arun Inam, a managing director of Signal Lake, LLC, was elected a director of the Issuer.

The response to Item 4 hereof is incorporated herein by reference. Except as set forth in this Schedule 13D, to the best knowledge of the Reporting Persons, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) between the Reporting Persons and any person with respect to any securities of the Issuer, including, but not limited to, transfer or voting of any of the securities of the Issuer, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, or a pledge or contingency the occurrence of which would give another person voting power or investment power over the securities of the Issuer.
