The Reporting Persons purchased the Common Stock based on the belief that such securities, at current market prices, are significantly undervalued and represent an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities, and the availability of Common Stock at desirable prices, the Reporting Persons may endeavor to increase their position in the Issuer through, among other things, the purchase of Common Stock in open market or private transactions on such terms and at such times as the Reporting Persons deem advisable. The Reporting Persons intend to review their investment in the Issuer on a continuing basis taking into consideration various factors, including the Issuer's business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for shares of Common Stock and the Issuer, in particular, as well as other developments and other investment opportunities. Based upon such review, the Reporting Persons will take such actions in the future as the Reporting Persons may deem appropriate in light of the circumstances existing from time to time, which may include further acquisitions of shares of Common Stock of the Issuer or disposal of some or all of the shares of Common Stock of the Issuer owned by the Reporting Persons or otherwise acquired by the Reporting Persons, either in the open market or in privately negotiated transactions. Any open market or privately negotiated purchases or sales, acquisition recommendations or proposals or other transactions concerning the Issuer may be made at any time without prior notice. Any alternative may depend upon a variety of factors, including, without limitation, current and anticipated future trading prices of the securities, the financial condition, results of operations and prospects of the Issuer and general industry conditions, the availability, form and terms of financing, other investment and business opportunities, general stock market and economic conditions, tax considerations and other factors. Although the foregoing reflects plans and proposals presently contemplated by each Reporting Person with respect to the Issuer, the foregoing is subject to change at any time and dependent upon contingencies and assumed and speculative conditions, and there can be no assurance that any of the actions set forth above will be taken. HPE has been a shareholder of the Issuer for approximately four years, is disappointed with the Issuer's stock price performance over that time period and has concerns about the persistent undervaluation of the Common Stock. In an effort to address this underperformance and drive shareholder value, the Reporting Persons may initiate and engage in discussions with the Issuer's management, board of directors, and/or other shareholders covering a range of subjects, including relative to operating performance, capital allocation (including stock buybacks) and governance of the Issuer. Depending upon each factor discussed above and any other factor (which may be unknown at this time) that is, or may become relevant, the Reporting Persons may consider, among other things: (a) the acquisition by the Reporting Persons of additional securities of the Issuer, the disposition of securities of the Issuer, or the exercise of convertible securities of the Issuer; (b) an extraordinary corporate transaction involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) changes in the present board of directors or management of the Issuer; (e) a material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer's business or corporate structure; (g) changes in the Issuer's articles of incorporation, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing any class of the Issuer's securities to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) any action similar to those enumerated above. Except to the extent that the foregoing may be deemed to be a plan or proposal, none of the Reporting Persons currently has any plans or proposals that relate to or would result in any of the actions specified in clause (a) through (j) of Item 4 of Schedule 13D. Depending upon the foregoing factors and to the extent deemed advisable in light of their general investment policies, or other factors, the Reporting Persons may, at any time and from time to time, formulate other purposes, plans or proposals regarding the Issuer or the Common Stock, or any other actions that could involve one or more of the types of transactions or have one or more of the results described in paragraphs (a) through (j) of Item 4 of Schedule 13D. The foregoing is subject to change at any time, and there can be no assurance that any of the Reporting Persons will take any of the actions set forth above.
