The holders of Common Stock are entitled to one vote per share on all matters to be voted on by the stockholders, and there are no cumulative voting rights. Generally, all matters to be voted on by stockholders must be approved by a majority of the votes entitled to be cast by all shares of Common Stock present in person or represented by proxy, voting together as a single class, subject to any voting rights granted to holders of any preferred stock; provided, however, that in all director elections that are contested, the nominees for election as a director shall be elected by a plurality of the votes cast. For purposes of the foregoing, an election shall be “contested” if, as of the tenth day preceding the date of the filing of the Company’s definitive proxy statement for such meeting of stockholders, the number of nominees for director exceeds the number of directors to be elected. The Board of Directors is divided into three classes of directors, as described below.

The holders of Common Stock are entitled to receive ratable dividends, if any, payable in cash, in stock or otherwise, as and when declared from time to time by the Board of Directors out of funds legally available for the payment of dividends, subject to any preferential rights that may be applicable to any outstanding preferred stock.

In the event of a liquidation, dissolution, or winding up of the Company, after payment in full of all outstanding debts and other liabilities, the holders of Common Stock are entitled to share ratably in all remaining assets, subject to prior distribution rights of preferred stock, if any, then outstanding. No shares of Common Stock have preemptive rights or other subscription rights to purchase additional shares of Common Stock. There are no redemption or sinking fund provisions applicable to the Common Stock. All outstanding shares of Common Stock are fully paid and nonassessable.

The rights, preferences, and privileges of holders of Common Stock will be subject to, and may be adversely affected by, the rights of holders of any preferred stock that may be issued in the future, as described below. All shares of Common Stock that are acquired by the Company shall be available for reissuance by the Company, at the sole-discretion of the Board of Directors at any time.

The transfer agent and registrar for the Common Stock is Broadridge Corporate Issuer Solutions, LLC, and its telephone number is ###-###-####.

The Common Stock is listed for trading on Nasdaq Global Select Market under the ticker symbol “BLKB.”

Certain provisions of the DGCL, the Certificate of Incorporation and Bylaws may have the effect of delaying, deferring or preventing a change in control of the Company or deterring tender offers for Common Stock, proxy contests or other takeover attempts, including discouraging attempts that might result in the payment of a premium over the market price for the shares of Common Stock.

We are subject to Section 203 of the DGCL, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the date the person became an interested stockholder, unless:

•the board of directors approved the transaction in which the stockholder became an interested stockholder prior to the date the interested stockholder attained that status;

•when the stockholder became an interested stockholder, he or she or it owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding shares owned by persons who are directors and also officers, as well as certain shares owned by employee benefits plans; or

•on or subsequent to the date the business combination is approved by the board of directors, the business combination is authorized by the affirmative vote of at least 66 2/3% of the voting stock of the corporation at an annual or special meeting of stockholders.

Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or is an affiliate or associate of the corporation, and within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock.

Classified Board of Directors. The Board of Directors is divided into three classes of directors, as nearly equal in number as possible, with each class serving a staggered term of three years. Any vacancy on the Board of Directors, regardless of the reason for the vacancy, may be filled by vote of the majority of the directors then in office, except in the case of a vacancy caused by action of the stockholders, which vacancy may only be filled by the stockholders. Directors may be removed from office at any time with or without cause, but only by the holders of a majority of the shares entitled to vote at an election of directors. The classification of directors will have the effect of making it more difficult for stockholders to change the composition of the Board of Directors and could also discourage a third-party from making a tender offer or otherwise attempting to obtain control of the Company, and may maintain the incumbency of the Board of Directors.

Advance notice requirement for stockholder proposals, including director nominations. The Bylaws contain an advance notice procedure for stockholders proposals to be brought before a meeting of stockholders, including any proposed nominations of persons for election to the Board of Directors. Stockholders at a meeting may only consider proposals or nominations specified in the notice of meeting, or brought before the meeting by or at the direction of the Board of Directors or by a stockholder who was a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting, who has given to the Company’s Secretary timely written notice, in proper form, of the stockholder’s intention to bring that business before the meeting, and who has otherwise complied with the Bylaws. Although the Bylaws do not give the Board of Directors the power to approve or disapprove stockholder nominations of candidates for election to the Board of Directors or proposals regarding other business to be conducted at a special or annual meeting of the stockholders, the Bylaws may have the effect of precluding the conduct of business at a meeting if the proper procedures are not followed, or may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of the Company.

“Blank” Preferred Stock. The Board of Directors has the authority to issue up to an aggregate of 20,000,000 shares of preferred stock in one or more classes or series and to determine, with respect to any such class or series, the designations, powers, preferences and rights of such class or series, and the qualifications, limitations and restrictions thereof, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption (including sinking fund provisions), redemption prices, liquidation preferences, and the number of shares constituting any class or series or the designation of such class or series, without further vote or action by the stockholders. This preferred

stock could have terms that may discourage a potential acquirer from making, without first negotiating with the Board of Directors, an acquisition attempt through which such acquirer may be able to change the composition of the Board of Directors, including a tender offer or other takeover attempt. No shares of preferred stock are currently outstanding.

Emergency Special Meeting of the Board of Directors. The Board of Directors possesses the authority to call and hold emergency special meetings of the Board of Directors with less than forty-eight hours’ notice. This power to hold an emergency special meeting of the Board of Directors on short notice could discourage a potential acquirer from launching a bid to acquire majority ownership of the Company, a proxy solicitation in order to replace the current Board of Directors, or otherwise attempting to obtain control of the Company, as such attempts could quickly be thwarted or denied by the Board of Directors.
