On November 9, 2010, BakBone Software Incorporated (the “Company”) and Quest Software, Inc. (“Quest”) announced the execution of an Arrangement Agreement, dated as of November 8, 2010, among Quest, Bolts Acquisition Corporation, a Canadian corporation and a wholly-owned subsidiary of Quest (“Acquisition Sub”) and the Company (the “Arrangement Agreement”), which contemplates the acquisition by Quest, through Acquisition Sub, of all of the outstanding equity securities of the Company pursuant to a “plan of arrangement” (the “Arrangement”) under Canadian law. Upon the closing of the Arrangement, (i) the Company will become a wholly-owned subsidiary of Quest, (ii) each of the Company’s common shares issued and outstanding immediately prior to the closing will be acquired for USD$0.33 in cash, (iii) each of the Company’s Series A Preferred shares will be acquired for USD$1.291667 in cash and (iv) all outstanding options and warrants to acquire the Company’s common shares will be terminated for no consideration. In addition, in fulfillment of certain obligations of the Company in connection with its acquisition of ColdSpark, Inc. in May 2009, the Company will, concurrently with the consummation of the Arrangement, become obligated to issue certain additional common shares and pay approximately USD$4.1 million to the former shareholders of ColdSpark, Inc. The aggregate purchase price for the transaction is approximately USD$55 million, including the payment of certain debt obligations and net of anticipated cash on hand. GCA Savvian is acting as financial advisor to the Company.

The Arrangement is to be implemented by way of a statutory plan of arrangement and is subject to the approval of (i) 66 2/3% of the votes cast by the Company’s security holders, including common shareholders, Series A Preferred shareholders and holders of stock options and warrants, voting as a single class, and (ii) a simple majority of the votes cast by the common shareholders (excluding the shares held by certain entities affiliated with JK&B Capital, the Company’s largest common shareholder). The JK&B Capital-affiliated shareholders, affiliates of VantagePoint Venture Partners, and each of the Company’s directors who owns common shares (collectively representing 100% of the outstanding Series A Preferred shares (the “Preferred Stock”) and approximately 16% of the outstanding common shares), have entered into Voting and Support Agreements with Quest and Acquisition Sub providing, among other things, that they will vote in favor of the resolutions approving the Arrangement. The foregoing descriptions of each of the Voting and Support Agreements is qualified in its entirety by reference to the forms of Voting and Support Agreement attached hereto as Exhibits 10.1 and 10.2, which are incorporated herein by reference.

The completion of the Arrangement must also be approved by the Court of Queen’s Bench, Alberta, Canada and is subject to other closing conditions as set forth in the Arrangement Agreement.

The Company has made various representations and warranties and agreed to specified covenants in the Arrangement Agreement, including covenants relating to the Company’s conduct of its business between the date of the Arrangement Agreement and the closing of the Arrangement, restrictions on solicitation of proposals with respect to alternative transactions, public disclosures and other matters. The Arrangement Agreement contains certain termination rights of Quest and the Company and provides that, upon the termination of the Arrangement Agreement under specified circumstances, the Company will be required to pay Quest a termination fee of either USD$600,000 or USD$2,350,000, as applicable. In addition, upon the

termination of the Arrangement Agreement under certain of the circumstances where a termination fee is payable, as well as certain additional circumstances where no termination fee is payable, the Company will be required to pay Quest an expense reimbursement of up to USD$800,000.

The respective boards of directors of Quest and the Company have approved the Arrangement Agreement, and the Company’s board of directors recommends that shareholders of the Company vote in favor of resolutions approving the Arrangement. The two directors elected to the Company’s board of directors by the VantagePoint Shareholders (as defined below) abstained from voting on all matters related to the Arrangement Agreement and the Arrangement. The Arrangement is not subject to the approval of Quest’s shareholders.

The foregoing description of the Arrangement and the Arrangement Agreement is qualified in its entirety by reference to the Arrangement Agreement attached hereto as Exhibit 2.1, which is incorporated herein by reference.

The Arrangement Agreement has been included to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company. The Arrangement Agreement contains representations and warranties that the Company has made to Quest. Such representations, warranties and covenants (i) have been made only for purposes of the Arrangement Agreement, (ii) have been qualified by confidential disclosures made to Quest in connection with the Arrangement Agreement, (iii) are subject to materiality qualifications contained in the Arrangement Agreement that may differ from what may be viewed as material by investors, (iv) were made only as of the date of the Arrangement Agreement or such other date as is specified in the Arrangement Agreement, and (v) have been included in the Arrangement Agreement for the purpose of allocating risk between the contracting parties rather than establishing matters as facts. Accordingly, investors should not rely on the representations and warranties as characterizations of the actual state of facts at the time they were made or otherwise.

In connection with entering into the Arrangement Agreement, the Company also entered into two separate agreements with groups of its shareholders, both intended to facilitate the Arrangement Agreement and the Arrangement, as follows:

First, pursuant to an Agreement dated as of November 8, 2010 (the “VantagePoint Agreement”) among the Company, VantagePoint Venture Partners IV (Q), L.P., VantagePoint Venture Partners IV, L.P. and VantagePoint Venture Partners IV Principals Fund, L.P. (collectively, the “VantagePoint Shareholders”), the VantagePoint Shareholders have agreed, concurrently with the consummation of the Arrangement, to accept cash consideration equal to USD$1.291667 per share of Preferred Stock held by them, in lieu of the USD$1.49475 (CDN$1.50) per share amount which the VantagePoint Shareholders would otherwise be entitled to receive with respect to their Preferred Stock as a result of the Arrangement, as set forth in the Company’s charter documents (assuming an exchange rate of CDN$1.002900 to USD$1.00 as quoted by WM/Reuters on November 8, 2010). The VantagePoint Agreement also provides for mutual general releases between the Company and the VantagePoint Shareholders and other persons associated with them. The VantagePoint Agreement is terminable by the VantagePoint Shareholders upon any amendment of the Arrangement Agreement to alter the amount of any of the consideration payable thereunder and certain other matters, or upon any amendment of the ColdSpark Agreement (as defined below), and terminates automatically upon any termination of the Arrangement Agreement. The foregoing description is qualified in its entirety by reference to the VantagePoint Agreement attached hereto as Exhibit 10.3, which is incorporated herein by reference.

Second, pursuant to a Settlement Agreement and General Release of Claims dated as of November 8, 2010 (the “ColdSpark Agreement”) between the Company and JK&B Capital IV,

JK&B Capital IV QIP and Tom Neustaetter, individually and in his capacity as attorney-in-fact for and on behalf of the former shareholders of ColdSpark, Inc. (collectively, the “ColdSpark Shareholders”), the ColdSpark Shareholders have agreed, concurrently with the consummation of the Arrangement, to accept USD$4,106,000 as payment in full of the remaining cash consideration owed by the Company to the ColdSpark Shareholders pursuant to an Agreement and Plan of Merger dated as of May 11, 2009, pursuant to which the Company acquired ColdSpark, Inc., in lieu of the USD$6,625,000 to which the ColdSpark Shareholders would otherwise be entitled thereunder. The ColdSpark Agreement also provides for mutual general releases between the Company and the ColdSpark Shareholders and other persons associated with them. The ColdSpark Agreement is terminable by the ColdSpark Shareholders upon any amendment of the Arrangement Agreement to alter the amount of any of the consideration payable thereunder and certain other matters, or upon any amendment of the VantagePoint Agreement, and terminates automatically upon any termination of the Arrangement Agreement. The foregoing description is qualified in its entirety by reference to the ColdSpark Agreement attached hereto as Exhibit 10.4, which is incorporated herein by reference.
