MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT

We are pleased to report that the boards of directors of Sand Hill IT Security Acquisition Corp. and St. Bernard Software, Inc. have each unanimously approved a merger of the two companies under the terms of a merger agreement. We are proposing the merger because we believe it will benefit the stockholders of both companies, and we ask for your support in voting for the merger proposals at our respective special meetings.

As a result of the proposed merger, St. Bernard will become a wholly owned subsidiary of Sand Hill. Upon completion of the merger, each outstanding share of St. Bernard common stock will be converted into the right to receive 0.421419 shares of Sand Hill common stock. The merger is intended to qualify as a tax-free reorganization for U.S. federal income tax purposes.

Based on the outstanding shares of St. Bernard common stock as of ________, 2006, Sand Hill would be obligated to issue up to approximately 9,759,600 shares of Sand Hill common stock and reserve an additional approximately 1,120,400 shares of Sand Hill common stock for future issuance in connection with Sand Hill’s assumption of St. Bernard’s outstanding options and warrants. Stockholders of Sand Hill will continue to own their existing shares of Sand Hill common stock and their existing Sand Hill warrants and units.

Sand Hill common stock, warrants and units are listed on the OTC Bulletin Board under the symbols SHQC, SHQCW and SHQCU, respectively, and will be listed under the symbols _____, _____ and _____, respectively, following the merger. On March 10, 2006, the closing price of Sand Hill common stock, warrants and units was $5.30, $0.81 and $7.10, respectively.

We encourage you to read this joint proxy statement/prospectus, including the section entitled “RISK FACTORS” beginning on page __, before voting.

Sand Hill and St. Bernard have each scheduled a special stockholder meeting in connection with the respective votes required. Your vote is very important. Whether or not you plan to attend your respective company’s special stockholder meeting, please take the time to vote by marking your votes on the enclosed proxy card, signing and dating the proxy card, and returning it to your respective company in the enclosed envelope.

To the Stockholders of Sand Hill IT Security Acquisition Corp.:

You are cordially invited to attend a special meeting of the stockholders of Sand Hill IT Security Acquisition Corp., relating to the proposed merger of Sand Hill Merger Corp., a wholly-owned subsidiary of Sand Hill, and St. Bernard Software, Inc., which will be held at _________ on _____________, 2006, at _____________________________, Suite ______, __________________, California _________.

At this important meeting, you will be asked to consider and vote upon the following proposals:

•	to adopt the Agreement and Plan of Merger, dated as of October 26, 2005, among Sand Hill, Sand Hill Merger Corp., a wholly-owned subsidiary of Sand Hill, and St. Bernard, and the transactions contemplated by the merger agreement, as amended;

•	to adopt the amended and restated certificate of incorporation of Sand Hill to change the name of Sand Hill to St. Bernard Software, Inc. and to remove certain provisions related to a business combination that were put in place as a result of our being a Targeted Acquisition Corporation;

•	to adopt the St. Bernard Software, Inc. 1992 Stock Option Plan, the St. Bernard Software, Inc. 2000 Stock Option Plan and the St. Bernard Software, Inc. 2005 Stock Option Plan; and

•

to consider and vote upon a proposal to adjourn the special meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event there are not sufficient votes at the time of the special meeting to adopt the merger proposal, the amendment proposal or the stock option plans proposal.

The adoption of the merger proposal is not conditioned on the adoption of the amendment proposal, the stock option plans proposal or the adjournment proposal. However, the adoption of the amendment proposal and the stock option plans proposal is conditioned upon the adoption of the merger proposal.

After completion of the merger, if no holders of shares of Sand Hill common stock have demanded that Sand Hill convert their shares into a pro rata portion of the trust account holding a substantial portion of the net proceeds of Sand Hill’s initial public offering, then Sand Hill stockholders will own approximately 34.4% of the combined company’s issued and outstanding shares of common stock. If one or more of Sand Hill’s stockholders vote against the merger proposal and demand that Sand Hill convert their shares into a pro rata portion of the trust account, then Sand Hill’s stockholders will own less than approximately 34.4% of the combined company’s issued and outstanding shares of common stock after completion of the merger.

The affirmative vote of a majority of the outstanding shares of Sand Hill common stock on the record date is required to approve the merger proposal and the amendment proposal, and the affirmative vote of a majority of the shares of Sand Hill’s common stock present in person or represented by proxy at the Sand Hill special meeting is required to approve each of the stock option plans proposal and the adjournment proposal. Each Sand Hill stockholder that holds shares of common stock issued in Sand Hill’s initial public offering has the right to vote against the merger proposal and at the same time demand that Sand Hill convert such stockholder’s shares into cash equal to a pro rata portion of the trust account in which a substantial portion of the net proceeds of Sand Hill’s initial public offering, plus interest thereon, are deposited. These shares will be converted into cash only if the merger is completed. However, if the holders of 20% or more of the shares of common stock issued in Sand Hill’s initial public offering vote against the merger and demand conversion of their shares into a pro rata portion of the trust account, then Sand Hill will not be able to consummate the merger. Sand Hill’s initial stockholders, who purchased their shares of common stock prior to its initial public offering and presently own an aggregate of approximately 19.6% of the outstanding shares of Sand Hill common stock, have agreed to vote their shares of Sand Hill common stock purchased prior to the initial public offering on the merger proposal in the same manner as how the majority of the shares of common stock held by all other Sand Hill stockholders are voted on the merger proposal.

Sand Hill’s shares of common stock, warrants and units are listed on the Over-the-Counter Bulletin Board under the symbols SHQC, SHQCW and SHQCU, respectively. St. Bernard’s securities are not listed or quoted on any national securities exchange, the Nasdaq Stock Market, or the Over-the-Counter Bulletin Board. On March 10, 2006, the closing sale price of Sand Hill common stock, warrants and units, was $5.30, $0.81 and $7.10, respectively.

After careful consideration of the terms and conditions of the proposed merger agreement, the amendment proposal, the stock option plans proposal and the adjournment proposal, the board of directors of Sand Hill has determined that the merger agreement, the transactions contemplated thereby, the amendment proposal, the stock option plans proposal and the adjournment proposal are fair to and in the best interests of Sand Hill and its stockholders. The board of directors of Sand Hill did not obtain a fairness opinion in connection with making these determinations. The board of directors of Sand Hill unanimously recommends that you vote or give instructions to vote “FOR” the adoption of the merger proposal, the amendment proposal, the stock option plans proposal and the adjournment proposal.

Enclosed is a notice of special meeting and proxy statement containing detailed information concerning the merger agreement, the transactions contemplated thereby and the stock option plans. Whether or not you plan to attend the Sand Hill special meeting, we urge you to read this material carefully.

I look forward to seeing you at the meeting.

Sincerely,

QUESTIONS AND ANSWERS ABOUT THE MERGER

The following questions and answers briefly address some commonly asked questions about the merger, the special meetings of the stockholders of Sand Hill and St. Bernard and the effect of the merger on the holders of common stock of Sand Hill and St. Bernard. These questions and answers may not include all of the information that is important to you. We urge you to read carefully this entire document, including the annexes and the other documents to which we have referred you.

Q.	Who is Sand Hill IT Security?	A.	Sand Hill is a “Targeted Acquisition Corporation”, or TAC, based in Menlo Park, California, organized to effect a merger, capital stock exchange or other similar business combination with an operating business in the IT security industry. Sand Hill’s goal is to enhance the value of Sand Hill by helping this targeted business achieve its business objectives by providing industry expertise, expansion capital for organic growth and the ability to issue shares in a public company as consideration for making additional targeted acquisitions.

Q.	Who is St. Bernard Software?	A.	St. Bernard is a recognized independent supplier of IT security software products and services, with a special emphasis on Secure Content Management, or SCM, including messaging security, with $28.7 million in gross billings for 2005. St. Bernard’s products protect businesses, government organizations and educational institutions from cyber attack, improve worker productivity, reduce legal liability and assist in meeting regulatory requirements for data/privacy protection. St. Bernard’s network-attached security products are delivered as appliances that connect into the data path between the Internet gateway and a company’s local area network. St. Bernard’s system security products consist of software that is installed on workstations and servers. St. Bernard has approximately 8,000 customers supporting over 3.5 million device licenses, primarily comprised of small to medium sized businesses, educational institutions and governmental organizations. The products offered by St. Bernard include Open File Manager, a data protection product; UpdateEXPERT, a patch and settings management product; iPrism, SCM, Internet access management product; and ePrism, SCM, messaging security e-mail filtering product. According to International Data Corporation, or IDC, in September 2005, St. Bernard’s iPrism product line was the leading Internet filtering appliance, enabling customers to manage and control employee access to millions of web sites that are updated continuously as part of St. Bernard’s fee-based Software as a Service”, or a “SaaS”, business model subscription service. Other St. Bernard products also have a subscription component that increases deferred revenue thereby increasing revenue predictability. St. Bernard’s revenue model includes revenue from appliance sales, software license sales and multi-year subscription for software/database updates. St. Bernard had revenues of $21.2 million in 2004 and revenues of $24.0 million in 2005. St. Bernard is a corporation that was founded in 1984 as Emerald Systems, Inc. In 1995, the corporation sold substantially all of its operating assets, changed its name to St. Bernard Software, Inc., and began its current operations to take advantage of its existing personnel and infrastructure. The St. Bernard operations rapidly moved into the data protection and IT security market. St. Bernard Software is a private company with headquarters in San Diego, California. IDC is a global provider of market intelligence and advisory services for the information technology and telecommunications industries. In September of 2005, IDC released a report titled, “Worldwide Secure Content Management 2005-2009 Forecast Update” from which the information that references IDC in this document has been gathered. St. Bernard subscribes to IDC information technology reports. There is no other relationship between IDC, St. Bernard or Sand Hill.


Q.	Why is Sand Hill proposing the merger with St. Bernard?	A.	The Sand Hill board of directors believes that the proposed merger between Sand Hill and St. Bernard is in the best interests of St. Bernard and its stockholders for the following primary reasons:

			· St. Bernard is positioned in a portion of the IT security market known as Secure Content Management, or SCM, that has experienced rapid growth and the appliance portion of SCM, according to IDC, is expected to continue to grow at 47% per year for the next five years; · St. Bernard reached $28.7 million in gross billings in 2005 and has experienced solid growth in the past five years; · Sand Hill believes that St. Bernard has an attractive SaaS, or Software as a Service, business model, with a subscription revenue component that increases revenue renewals, and, therefore, predictability. In 2005 subscription revenue accounted for approximately 59% of St. Bernard’s business; · St. Bernard has approximately 8,000 active customers, with very high retention rates, on the order of 80% to 95%, resulting in strong subscription renewals (i.e.: repeat business) each year; · St. Bernard, according to IDC in September 2005, had the number one market position in web-filtering appliances; · St. Bernard targets the Small to Medium sized Enterprise, or SME, segment of the market as its primary focus, which, according to AMI Research in 2005, is underserved and is forecasted to grow 73% in 2006; and · Sand Hill believes that St. Bernard has a strong management team.

			Given the above, Sand Hill believes that a business combination with St. Bernard will provide Sand Hill stockholders with an opportunity to participate in a combined company in the IT security market with significant growth potential. See page ___.

Q.	Why is St. Bernard proposing the merger with Sand Hill?	A.	The St. Bernard board of directors believes that the proposed merger between Sand Hill and St. Bernard is in the best interests of St. Bernard and its stockholders for the following primary reasons:
			· As of October 26, 2005, Sand Hill had $21,565,510 in escrow, representing the net proceeds from its initial public offering. If the merger is consummated, at least 80% of the funds in the Sand Hill escrow account, less expenses of the merger, will be available for operations of the combined company. St. Bernard believes that because the combined company will have substantially greater capitalization than St. Bernard alone, the combined company will be in a better position than St. Bernard alone, to compete in the SCM marketplace. · St. Bernard believes that the skills and expertise of the officers and directors of Sand Hill, their collective access to acquisition opportunities and ideas, their contacts, and, in particular, Mr. Polanen’s and Mr. Broomfield’s expertise in the IT security market, will provide the combined company with increased opportunities for future acquisitions and growth.

Q.	What is being voted on at the Sand Hill special meeting?	A.	There are four proposals that stockholders of Sand Hill are being asked to vote on at the Sand Hill special meeting. The first proposal is to adopt the merger agreement and the transactions contemplated by the merger agreement. This proposal is referred to as the merger proposal. The second proposal is to adopt the amended and restated certificate of incorporation of Sand Hill to change the name of Sand Hill to St. Bernard Software, Inc. and to remove certain provisions related to a business combination that were put in place as a result of Sand Hill being a Targeted Acquisition Corporation. This proposal is referred to as the amendment proposal. The third proposal is to adopt the St. Bernard Software, Inc. 1992 Stock Option Plan, the St. Bernard Software, Inc. 2000 Stock Option Plan and the St. Bernard Software, Inc. 2005 Stock Option Plan for non-employee directors, officers and other key employees. This proposal is referred to as the stock option plans proposal. The fourth proposal allows the adjournment of the Sand Hill special meeting to a later date if necessary to permit further solicitation of proxies in the event that there are not sufficient votes at the time of the Sand Hill special meeting to approve the merger proposal, the amendment proposal or the stock option plans proposal. This proposal is referred to as the adjournment proposal.

Q.	What is being voted on at the St. Bernard special meeting?	A.	There are two proposals that stockholders of St. Bernard are being asked to vote on at the St. Bernard meeting. The first proposal is to adopt the merger agreement and the transactions contemplated by the merger agreement. We refer to this proposal as the merger proposal. The second proposal allows the adjournment of the St. Bernard special meeting to a later date if necessary to permit further solicitation of proxies in the event that there are not sufficient votes at the time of the St. Bernard special meeting to approve the merger proposal. We refer to this proposal as the adjournment proposal.

Q.	Does the Sand Hill board of directors recommend voting in favor of the merger proposal, the amendment proposal, the stock option plans proposal and the adjournment proposal?	A.	Yes. After careful consideration, Sand Hill’s board of directors has determined unanimously that the merger proposal, the amendment proposal, the stock option plans proposal and the adjournment proposal are fair to, and in the best interests of, Sand Hill and its stockholders. The board of directors of Sand Hill did not obtain a fairness opinion in connection with making these determinations. Sand Hill’s board recommends that Sand Hill stockholders vote or instruct your vote to be cast “FOR” the adoption of the merger agreement, the amendment proposal, the stock option plans proposal and the adjournment proposal. Please see “The Merger Proposal - Sand Hill Reasons for the Merger” on page ___.

Q.	Does the St. Bernard board of directors recommend voting in favor of the merger proposal and the adjournment proposal?	A.	Yes. After careful consideration, St. Bernard’s board of directors has determined unanimously that the merger proposal and the adjournment proposal are fair to, and in the best interests of, St. Bernard and its stockholders. St. Bernard’s board recommends that St. Bernard stockholders vote or instruct your vote to be cast “FOR” the adoption of the merger agreement and the adjournment proposal. Please see “The Merger Proposal - St. Bernard Reasons for the Merger” on page ___.

Q.	What vote is required in order to adopt the merger proposal at the Sand Hill special meeting?	A.	The adoption of the merger agreement and the transactions contemplated by the merger agreement by the Sand Hill stockholders will require the affirmative vote of a majority of the outstanding shares of Sand Hill’s common stock on the Sand Hill record date. Sand Hill’s initial stockholders, who purchased their shares of common stock prior to its initial public offering and presently own an aggregate of approximately 19.6% of the outstanding shares of Sand Hill common stock, have agreed to vote their shares of Sand Hill common stock purchased prior to the initial public offering on the merger proposal in the same manner as how the majority of the shares of common stock held by all other Sand Hill stockholders are voted on the merger proposal. However, if the holders of 20% or more of the shares of common stock issued in Sand Hill’s initial public offering vote against the merger and demand that Sand Hill convert their shares into a pro rata portion of the trust account, then, pursuant to the terms of Sand Hill’s certificate of incorporation, the merger will not be consummated. No vote of the holders of any warrants issued by Sand Hill is necessary to adopt the merger proposal, and Sand Hill is not asking the warrant holders to vote on the merger proposal.

Q.	What vote is required in order to adopt the amendment proposal at the Sand Hill special meeting?	A.	The adoption of the amendment proposal by the Sand Hill stockholders will require the affirmative vote of a majority of the outstanding shares of Sand Hill’s common stock on the Sand Hill record date.

Q.	What vote is required in order to adopt the stock option plans proposal at the Sand Hill special meeting?	A.	The adoption of the stock option plans proposal by the Sand Hill stockholders will require the affirmative vote of a majority of the shares of Sand Hill’s common stock present in person or represented by proxy at the Sand Hill special meeting.

Q.	What vote is required in order to adopt the adjournment proposal at the Sand Hill special meeting?	A.	The adoption of the adjournment proposal by the Sand Hill stockholders will require the affirmative vote of the majority of the shares of Sand Hill’s common stock present in person or represented by proxy at the Sand Hill special meeting.

Q.	Are the proposals of the Sand Hill special meeting conditioned on each other?	A.	The adoption of the merger proposal is conditioned on the adoption of the amendment proposal and the adoption of the amendment proposal is conditioned on the adoption of the merger proposal. The adoption of neither the merger proposal nor the amendment proposal is conditioned on the adoption of the stock option plans proposal or the adjournment proposal. The adoption of the stock option plans proposal, however, is conditioned upon the adoption of the merger proposal and the amendment proposal.

Q.	What vote is required in order to adopt the merger proposal at the St. Bernard special meeting?	A.	The adoption of the merger proposal by the St. Bernard stockholders will require the affirmative vote of a majority of the outstanding shares of St. Bernard’s common stock on the St. Bernard record date. No vote of the holders of any warrants or options issued by St. Bernard is necessary to adopt the merger proposal, and St. Bernard is not asking the warrant holders or option holders to vote on the merger proposal.

Q.	What vote is required in order to adopt the adjournment proposal at the St. Bernard special meeting?	A.	The adoption of the adjournment proposal by the St. Bernard stockholders will require the affirmative vote of the majority of the shares of St. Bernard’s common stock present in person or represented by proxy at the St. Bernard special meeting. The adoption of the adjournment proposal is not conditioned on the adoption of the merger proposal.

Q.	What will Sand Hill security holders receive in the merger?	A.	Sand Hill security holders will continue to hold the Sand Hill securities they currently own, and will not receive any of the shares of common stock, replacement options or replacement warrants issued in connection with the merger. The stockholders of St. Bernard will receive all of the shares of common stock, replacement options and replacement warrants being issued by Sand Hill in the merger.

Q.	What will St. Bernard stockholders, option holders and warrant holders receive in the merger?	A.	It is expected that holders of St. Bernard common stock will hold approximately 65.6% of the outstanding shares of Sand Hill common stock immediately following the closing of the merger, based on the number of shares of Sand Hill and St. Bernard common stock outstanding as of October 26, 2005. In the merger, Sand Hill will issue a combination of shares of common stock, replacement options and replacement warrants to holders of St. Bernard common stock, options and warrants. The total amount of shares of Sand Hill common stock to be issued or that will underlie replacement options and replacement warrants is 10,880,000. Holders of St. Bernard common stock, options and warrants are entitled to receive their pro rata portion of this 10,880,000 figure. This results in an exchange ratio of 0.421419 shares of Sand Hill common stock, replacement options or replacement warrants for each share of St. Bernard common stock or options or warrants to purchase St. Bernard common stock outstanding. Based upon the number of shares of St. Bernard common stock outstanding and the number of shares issuable for St. Bernard common stock pursuant to outstanding options and warrants as of October 26, 2005, Sand Hill will issue approximately 9,759,600 shares of common stock at the close of the merger. The holders of options and warrants to purchase shares of the common stock of St. Bernard will receive, in exchange for those options and warrants, replacement options and replacement warrants to purchase approximately 1,120,400 shares of Sand Hill common stock. To the extent that outstanding St. Bernard options or warrants are exercised prior to the closing of the merger, the number of shares of Sand Hill common stock that would be issued at the closing of the merger would increase and the number of the shares of Sand Hill common stock that would be subject to replacement options or replacement warrants to be issued at the closing of the merger would decrease by a like amount. For a complete description of the post-closing fully diluted capitalization of Sand Hill please see “Beneficial Ownership of Securities.”

Q.	What is the structure of the merger?	A.	Under the merger agreement, St. Bernard and Sand Hill Merger Corp., a wholly-owned subsidiary of Sand Hill, will merge, with St. Bernard surviving as a wholly-owned subsidiary of Sand Hill (referred to as the merger). The merger will be accounted for as an equity recapitalization of St. Bernard for financial reporting purposes.

Q.	How much of the combined company will existing Sand Hill stockholders own?	A.	After completion of the merger, if no holders of Sand Hill common stock demand that Sand Hill convert their shares into a pro rata portion of the trust account holding a substantial portion of the net proceeds of Sand Hill’s initial public offering, then Sand Hill’s stockholders will own approximately 34.4% of the combined company’s issued and outstanding shares of common stock. If one or more of Sand Hill’s stockholders vote against the merger proposal and demand that Sand Hill convert their shares into a pro rata portion of the trust account, then Sand Hill’s stockholders will own less than approximately 34.4% of the combined company’s issued and outstanding shares of common stock after completion of the merger. In either case, the balance of the issued and outstanding shares of Sand Hill’s common stock will be owned by the stockholders of St. Bernard.

Q.	Why is Sand Hill proposing the stock option plans?	A.	Sand Hill is proposing the stock option plans because it has agreed to assume the outstanding options of St. Bernard at the closing of the merger and the plans need to remain outstanding under which such options were issued as those plans govern the terms of the options. The adoption of the 2005 Stock Option Plan will also enable the combined company to offer non-employee directors, officers, other key employees and consultants equity-based incentives, thereby helping to attract, retain and reward these participants and create value for the combined company’s stockholders.

Q.	What will the name of the combined company be after the merger?	A.	Sand Hill will change its name following completion of the merger to St. Bernard Software, Inc.

Q.	How much cash does Sand Hill hold in escrow?	A.	As of December 31, 2005, Sand Hill had $21,730,543 in escrow, which would equate to $5.29 per share of outstanding Sand Hill common stock to participate in the funds held in escrow.

Q.	Do stockholders of Sand Hill have conversion rights?	A.	If you hold shares of common stock issued in Sand Hill’s initial public offering, then you have the right to vote against the merger proposal and demand that Sand Hill convert these shares into a pro rata portion of the trust account in which a substantial portion of the net proceeds of Sand Hill’s initial public offering are held. We sometimes refer to these rights to vote against the merger and demand conversion of the shares into a pro rata portion of the trust account as conversion rights.

Q.	If stockholders of Sand Hill have conversion rights, how do they exercise them?	A.	If you wish to exercise your conversion rights, you must vote against the merger and at the same time demand that Sand Hill convert your shares into cash. If, notwithstanding your vote, the merger is completed, then you will be entitled to receive a pro rata portion of the trust account in which a substantial portion of the net proceeds of Sand Hill’s initial public offering are held, including any interest earned thereon through the date of the Sand Hill special meeting. Based on the amount of cash held in the trust account on December 31, 2005, you will be entitled to convert each share of Sand Hill common stock that you hold into approximately $5.29. If you exercise your conversion rights, then you will be exchanging your shares of Sand Hill common stock for cash and will no longer own these shares. You will only be entitled to receive cash for these shares if you continue to hold these shares through the effective time of the merger and then tender your stock certificate to the combined company. If the merger is not completed, then your shares will not be converted to cash at this time, even if you so elected. See page ___.

Q.	What happens to the funds deposited in the trust account after consummation of the merger?	A.	Upon consummation of the merger:
			· the Sand Hill stockholders electing to exercise their conversion rights will receive their pro rata portion of the funds deposited in the trust account; and

			· the remaining funds will be released to the combined company, which intends to use its existing cash resources, along with funds released from the Sand Hill trust, to (1) enhance its SCM product offering, (2) further develop its products, (3) increase its international presence, and (4) improve its VAR and indirect sales channels, in addition to using its cash resources for working capital and for general corporate purposes.

Q.	What are the expected United States federal income tax consequences to the merger?	A.	The merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code. A St. Bernard stockholder’s receipt of Sand Hill common stock in the merger will be tax-free for United States federal income tax purposes. The receipt in the merger of warrants or options to purchase common stock of Sand Hill by a holder of St. Bernard warrants or options to purchase St. Bernard common stock will be tax-free for United States federal income tax purposes. However, a St. Bernard stockholder who exercises his or her appraisal rights and who receives cash in exchange for his or her shares of St. Bernard common stock generally will recognize gain or loss measured by the difference between the amount of cash received and the tax basis of such stockholder’s shares of St. Bernard common stock. A stockholder of Sand Hill who exercises conversion rights and effects a termination of the stockholder’s interest in Sand Hill will generally be required to recognize capital gain or loss upon the exchange of that stockholder’s shares of common stock of Sand Hill for cash, if such shares were held as a capital asset on the date of the merger. Such gain or loss will be measured by the difference between the amount of cash received and the tax basis of that stockholder’s shares of Sand Hill common stock. No gain or loss will be recognized by non-converting stockholders of Sand Hill. No gain or loss will be recognized by Sand Hill or St. Bernard as a result of the merger. For a description of the material federal income tax consequences of the merger, please see the information set forth in “Material Federal Income Tax Consequences of the Merger” on page ___.

Q.	Who will manage the combined company?	A.	The combined company will be managed by the current management of St. Bernard. John E. Jones, who is currently the President and Chief Executive Officer of St. Bernard, will become the President and Chief Executive Officer of the combined company. Alfred Riedler, who is currently the Chief Financial Officer of St. Bernard, will become the Chief Financial Officer of the combined company. Bart van Hedel, who is currently on the board of directors of St. Bernard, will continue as a board member of the combined company. Humphrey P. Polanen, who is currently the Chairman of the Board and Chief Executive Officer of Sand Hill, will continue as Chairman of the Board of the combined company. Scott R. Broomfield, who is currently the Executive Vice President of Corporate Development and on the board of directors of Sand Hill, will continue as a board member of the combined company.

Q.	What happens to Sand Hill if the merger is not consummated?	A.	If the merger is not consummated, Sand Hill will continue to search for an operating company to acquire. However, Sand Hill will be liquidated if it does not consummate a business combination by July 27, 2006. Upon such a liquidation, the net proceeds of Sand Hill’s initial public offering held in the trust account, plus any interest earned thereon, will be distributed pro rata to Sand Hill’s common stockholders, excluding Sand Hill’s initial stockholders who purchased their shares of common stock prior to its initial public offering.

Q.	What happens to St. Bernard if the merger is not consummated?	A.	If the merger is not consummated, St. Bernard will continue to operate as a private company.

Q.	When do you expect the merger to be completed?	A.	It is currently anticipated that the merger will be completed promptly following the special meetings of Sand Hill and St. Bernard.

Q.	Do I have appraisal rights?	A.	Sand Hill’s stockholders do not have appraisal or dissenters rights in connection with the merger. Holders of St. Bernard capital stock who hold their shares of St. Bernard capital stock of record and continue to own those shares through the effective time of the merger and who properly demand appraisal of their shares in writing on or before ____________, 2006 in accordance with the requirements of Section 262 of the General Corporation Law of the State of Delaware, or the DGCL, are entitled to appraisal rights as set forth in Section 262. A copy of Section 262 of the DGCL is attached to this proxy statement/prospectus as Annex F. Under Section 262, St. Bernard stockholders who comply with the procedures set forth in Section 262 will be entitled to have their shares appraised by the Delaware Court of Chancery and to receive cash payment of the fair value of the shares, exclusive of any element of the value arising from the accomplishment or expectation of the merger, together with a fair rate of interest, if any, as determined by the court. St. Bernard will send notice pursuant to Section 262 of the DGCL to the St. Bernard stockholders who are entitled to appraisal rights when St. Bernard mails this prospectus to the St. Bernard stockholders. See “The Merger Proposal - Appraisal or Dissenters Rights” on page ___.

Q.	If I am not going to attend the Sand Hill special meeting in person, should I return my proxy card instead?	A.	Yes. After carefully reading and considering the information contained in this document, please fill out and sign your proxy card. Then return the enclosed proxy card in the return envelope as soon as possible, so that your shares may be represented at the Sand Hill special meeting.

Q.	What will happen if I abstain from voting or fail to vote at the Sand Hill special meeting?	A.	Sand Hill will count a properly executed proxy marked ABSTAIN with respect to a particular proposal as present for purposes of determining whether a quorum is present. For purposes of approval, an abstention or failure to vote will have the same effect as a vote against the merger proposal, the amendment proposal, the stock options plan proposal and the adjournment proposal. However, if you want to convert your shares into a pro rata portion of the trust account in which a substantial portion of the net proceeds of Sand Hill’s initial public offering are held, you must vote against the merger and make an affirmative election to convert your shares of common stock on the proxy card. An abstention will have the same effect as a vote against the stock option plans proposal and the adjournment proposal, but a failure to vote will have no effect on the stock option plans proposal and the adjournment proposal, assuming that a quorum for the special meeting is present. Shares that are not voted or are broker non-voted or where the stockholder abstains from voting shall not be eligible to be converted into cash upon completion of the merger.

Q.	What do I do if I want to change my vote prior to the Sand Hill special meeting?	A.	Send a later-dated, signed proxy card to Sand Hill prior to the date of the Sand Hill special meeting or attend the special meeting in person and vote. Your attendance alone will not revoke your proxy. You also may revoke your proxy by sending a notice of revocation to Sand Hill at the address of Sand Hill’s corporate headquarters, on or before ____________, 2006.

Sand Hill

Sand Hill is a Targeted Acquisition Corporation, or TAC, focused on the IT security industry, organized under the laws of the State of Delaware on April 15, 2004. As a TAC, it was formed to effect a merger, capital stock exchange, asset acquisition or other similar business combination with an operating business in a specified industry. On July 30, 2004, Sand Hill successfully consummated an initial public offering of its units, with each unit consisting of one share of common stock and two warrants exercisable for shares of common stock, from which it derived net proceeds of approximately $22,022,462. The prices of Sand Hill’s common stock, warrants to purchase common stock and units (each unit consisting of a share of common stock and two warrants to purchase common stock) are quoted on the Over-the-Counter Bulletin Board under the symbols SHQC for the common stock, SHQCW for the warrants and SHQCU for the units. $20,961,000 of the net proceeds of the initial public offering were placed in a trust account and will be released to Sand Hill upon consummation of the merger. As of December 31, 2005, Sand Hill had $21,730,542 in escrow, which equates to $5.29 per share of outstanding Sand Hill common stock eligible to participate in the funds held in escrow. The balance of the net proceeds of $1,061,462 has been used and will be used by Sand Hill to pay the expenses incurred in its pursuit of a business combination, including the merger. Other than its initial public offering and the pursuit of a business combination, Sand Hill has not engaged in any business to date. If Sand Hill does not consummate a business combination by July 27, 2006 then, pursuant to its certificate of incorporation, Sand Hill’s officers must take all actions necessary to promptly dissolve and liquidate Sand Hill.

Sand Hill Merger Corp.

Sand Hill Merger Corp. is a wholly-owned subsidiary of Sand Hill formed solely for the purpose of the merger. Sand Hill Merger Corp.’s executive office is located at 3000 Sand Hill Road, Building 1, Suite 240, Menlo Park, California 94025, and its telephone number is (650) 926-7022. Sand Hill Merger Corp. will be merged with and into St. Bernard and the separate corporate existence of Sand Hill Merger Corp. will cease upon completion of the merger. St. Bernard will be a wholly-owned subsidiary of Sand Hill upon completion of the merger.

St. Bernard

St. Bernard is a corporation that was founded in 1984 as Emerald Systems, Inc. In 1995, the corporation sold substantially all of its operating assets, changed its name to St. Bernard Software, Inc., and began its current operations to take advantage of its existing personnel and infrastructure. The St. Bernard operations rapidly moved into the data protection and IT security market. St. Bernard Software is a recognized independent supplier of IT security software products and services, with a special emphasis on Secure Content Management, or SCM, including messaging security, with $28.7 million in gross billings for 2005. With its SaaS business model, St. Bernard’s products protect businesses, government organizations and educational institutions from cyber attack, improve worker productivity, reduce legal liability and assist in meeting regulatory requirements for data/privacy protection. St. Bernard’s network-attached security products are delivered as appliances that connect into the data path between the Internet gateway and a company’s local area network. Similar to a traditional household appliance, a security appliance is a dedicated computer with a specially configured ‘kernal level’ operating system that is plugged into the server stack, in front of a company’s firewall and, therefore, sees all inbound Internet traffic. St. Bernard’s system security products consist of software that is installed on workstations and servers. St. Bernard has approximately 8,000 customers supporting over 3.5 million device licenses, primarily comprised of small to medium sized businesses, educational institutions and governmental organizations. The products offered by St. Bernard include Open File Manager, a data protection product; UpdateEXPERT, a patch and settings management product; iPrism, SCM, Internet access management product; and ePrism, SCM, a messaging security, e-mail filtering product. According to IDC, in September 2005, St. Bernard’s iPrism product line was the leading Internet filtering appliance, enabling customers to manage and control employee access to millions of web sites that are updated continuously as part of St. Bernard’s fee-based subscription service. Other St. Bernard products also have a subscription component that increases deferred revenue thereby increasing revenue predictability. St. Bernard’s principal offices are located at 15015 Avenue of Science, San Diego, California 92128 and its telephone number at that location is (858) 524-2299. St. Bernard’s home page on the Internet is at http://www.stbernard.com, but the information on the St. Bernard website is not a part of this joint proxy statement/prospectus.

Sand Hill’s Business Rationale for Merging with St. Bernard

Sand Hill believes the proposed merger between Sand Hill and St. Bernard is in the best interests of Sand Hill and its stockholders for the following primary reasons:

Industry and Market Focus

St. Bernard is a recognized independent supplier of IT security software products and services, with a special emphasis on Secure Content Management, or SCM, including messaging security. According to IDC, SCM worldwide revenues reached $4.5 billion in 2004, representing a 27% increase over 2003. IDC has also concluded that web-filtering, a subset of SCM, reached $433 million in revenues in 2004, growing at 22% over 2003. Finally, IDC forecasts that the rate of growth for ‘appliance based web-filtering’, the portion of the market in which St. Bernard competes in, should increase by 47% per year between 2004 and 2009. According to IDC, appliances represent the fastest growing element of SCM. In addition to this market segment, St. Bernard also includes messaging security as part of its product offerings, thereby adding to the value of its business offerings.

St. Bernard focuses on the relatively underserved and high growth Small to Medium Enterprises (or SME) segment of the market. As estimated by AMI Partners, an SME oriented research firm, there are 232,000 small to medium sized businesses in the U.S. The SME segment is defined by AMI as businesses ranging from 50 to 999 employees. According to a study by AMI conducted in 2005, the SME segment is underserved, or under penetrated, in that only 22% of all small to medium sized businesses have installed comprehensive security management solutions. Sand Hill believes that this indicates that there is real opportunity for growth in this segment. According to this same AMI report, a total of an additional 15% of the SME market, or 35,000 businesses, plan to purchase security management solutions in 2006, representing a growth rate of 73% year over year. Sand Hill also additionally believes that the focus on SME is beneficial because security appliances tend to serve the market well because of their ease of installation and use. Brian Burk, an analyst with IDC research recently stated, “… security appliance sales will grow fast in the SME market because IT resources are scarce.”

Size and Growth

St. Bernard reached $28.7 million in gross billings and $24.0 million in revenues for the calendar year ended 2005. St. Bernard has recently experienced attractive growth in its market. From 2000 through 2004 St. Bernard has grown 182% based on annual revenues and was awarded a San Diego Deloitte “Technology Fast 50 of San Diego” award in both 2004 and 2005. In 2005, St. Bernard grew annual revenues 13.2% as compared with 2004.

Business Model

St. Bernard has a Software as a Service, or SaaS, business model that includes both web-filter and email-filter appliances and a database service subscription component. St. Bernard’s revenue model includes revenue from appliance sales and multi-year subscriptions for software/database updates and ePrism (messaging security - e-mail filtering). Sand Hill believes that St. Bernard’s sales cycles are shorter than an enterprise level sale because of: (1) its focus on the SME segment, (2) the average selling prices for St. Bernard products are usually lower than that of enterprise level products, and (3) its having an appliance form factor that results in the product being simple to install and simple to use. Specifically, St. Bernard focuses on small businesses that are defined as having between 50 and 499 employees and medium businesses that are defined as having 500 to 1,000 employees. Enterprises are defined as having more than 1,000 employees. The sales cycle from first customer contact to completed sale is typically 90 days for small and medium businesses. By contrast, sales cycles to enterprises are typically longer than 90 days due to a more complex approval requirement. The quicker sales cycle to small and medium businesses is primarily due to the lower dollar value of the products purchased and more willingness by these customers to purchase without on site sales calls.

The subscription element of St. Bernard’s business is particularly attractive because it operates as a “Software as a Service”, or a “SaaS” model. Sand Hill believes that this represents a stable portion of St. Bernard’s revenue base. As an example, customers subscribe to a Universal Resource Locator, or URL, database service for periods of anywhere from one to three years. Internet web pages are uniquely accessed and displayed through the use of URL’s. St. Bernard’s iPrism product employs a database of URL’s divided into 60 categories to monitor and/or block access to Web pages based on predetermined policies set by the customer. This URL database is organized into more than 60 categories and encompasses more than 6.5 million websites as of September 30, 2005. This database is updated each business day using a proprietary process of automated content assessment and classification, with manual verification. Subscribers to the update service receive updates each night. It is this security update subscription that Sand Hill believes helps create long term customer relationships, as well as providing for better predictability of future revenue. St. Bernard had deferred revenues of $16.1 million as of December 31, 2005. Although the cash is received up front, this deferred revenue is generally recognized as revenue ratably over the life of the contract. The result is that billings for the business are greater than the revenue booked in any quarter. For example, revenue for the year ended December 31, 2005 was $24.0 million, whereas gross billings were $28.7 million. The result is an increase to deferred revenue, as recorded on the balance sheet, and, Sand Hill believes, an enhanced predictability to the business.

Management Team

St. Bernard has a seasoned management team with specialized knowledge of its markets and, Sand Hill believes, the ability to lead the combined company in a changing environment. St. Bernard’s management team has been in place for a number of years and the Sand Hill board of directors believes that John E. Jones, who will be the President and Chief Executive Officer of the combined company, has the experience and strong understanding of the software security market and potential needs of customers to effectively lead the combined company.

Terms of the Merger Agreement

The Sand Hill board of directors believes that the merger agreement contains customary provisions for transactions of this type, including provisions to protect Sand Hill in the event an alternative transaction is proposed to St. Bernard. The Sand Hill board of directors believes that the price Sand Hill is paying for St. Bernard is equal to approximately 2.2x Enterprise Value/Sales, which it feels is below industry norms. It was important to Sand Hill’s board of directors it felt it was receiving appropriate value and that the merger agreement include customary provisions as it believed that such provisions would allow for a more efficient closing process and lower transaction expenses.

Please see “The Merger Proposal - Sand Hill Reasons for the Merger” on page ___.

St. Bernard’s Business Rationale for Merging with Sand Hill

The St. Bernard board of directors believes that the proposed merger between Sand Hill and St. Bernard is in the best interests of St. Bernard and its stockholders for the following primary reasons:

As of December 31, 2005, Sand Hill had $21,730,543 in escrow, representing the net proceeds from its initial public offering. If the merger is consummated, at least 80% of the funds in the Sand Hill escrow account, less expenses of the merger, will be available for operations of the combined company. St. Bernard believes that because the combined company will have substantially greater capitalization than St. Bernard alone, the combined company will be in a better position than St. Bernard alone, to compete in the SCM marketplace.

St. Bernard believes that the skills and expertise of the officers and directors of Sand Hill, their collective access to acquisition opportunities and ideas, their contacts, and, in particular, Mr. Polanen’s and Mr. Broomfield’s expertise in the IT security market, will provide the combined company with increased opportunities for future acquisitions and growth.

Security Market Characteristics and Industry Background

The IT security market continues to be attractive from a business perspective. In January of 2006, Goldman Sachs reported that IT security continues to be the highest spending priority amongst CIOs and CTOs in the U.S. for 2006. The industry is generally characterized by the following:

·	escalating volume of Internet attacks on business, industry and governments, reaching over 140,000 attacks in 2004;

·	increasing sophistication of attacks and increasing cost per attack;

·	material loss in employee productivity due to unauthorized Internet usage during working hours;

·	significant recent increases in government and regulatory requirements specifically targeting security, including but not limited to, Sarbanes-Oxley (SOX), HIPPA, BASEL II, Gramm-Leach-Bliley, GISRA, etc;

·	increases in customer demand for integrated, full solution product suites; and

·	a strong preference in SME for easy to install and easy to use security appliances.

Many organizations use the Internet to enable critical business applications that are accessed over their corporate networks. Many employees also use their organization’s computing resources for recreational “web surfing,” peer-to-peer file sharing, downloading of high-bandwidth content, instant messaging and other personal matters. However, unmanaged use of organizational computing and network resources, including Internet access, results in increased risk and cost to the organization, including increased security risks, loss of intellectual property, loss of a company’s customer and supplier data, lost employee productivity, increased network bandwidth consumption, and potential legal liability. This segment of IT security is commonly known as Secured Content Management, or SCM.

Traditionally, organizations have attempted to mitigate the legal liability, productivity and bandwidth waste risks through written policies governing acceptable employee use of computing resources, and they have sought to protect against external security risks with a combination of firewalls, intrusion detection/prevention software and anti-virus software. With the growth in spyware, key logging applications, and phishing sites, combined with the rapid increase in employee use of instant messaging and peer-to-peer file sharing and the proliferation of blended attacks on computing networks, organizations are finding that existing security measures leave significant time and technology gaps in their protection. Written Internet access and software application use policies are easily ignored, difficult to enforce and do not proactively curtail undesirable Internet and software application usage. Firewalls can provide protection against external threats such as hacking, but do little to prevent employees from accessing unauthorized data from within an organization. Anti-virus software provides protection from e-mail borne viruses, but does not prevent the possible theft or corruption of corporate data by spyware and offers only limited protection against viruses that proliferate via peer-to-peer networks and instant messaging. Existing anti-virus and anti-spyware software also requires time to identify and reverse engineer the virus or spyware application before it can be remediated and removed from infected systems.

Given the necessity of corporate Internet access and the continuing adoption of the web as a mass communication, entertainment, information and commerce medium, Sand Hill believes there is a significant opportunity for SCM solutions, including messaging security, that effectively addresses the needs of organizations to manage employee usage of the computing environment, including Internet access and desktop application use. Additionally, although the web and e-mail are the primary drivers of Internet traffic today, the rapid emergence of Internet-enabled applications creates the need for software that applies management policies to file types, applications, and protocols, as well as web pages, at multiple points on the information technology infrastructure. Software tools are needed to implement policy-based bandwidth management and regulation of applications such as instant messaging, peer-to-peer file exchange tools, interactive games and desktop software applications. These solutions must also be adaptable enough to manage new applications and technologies as they are developed.

The Merger

The merger agreement provides for the merger of Sand Hill Merger Corp. with and into St. Bernard. The merger agreement was executed on October 26, 2005 and amended on December 15, 2005. Following consummation of the merger, St. Bernard will continue as the surviving company and a wholly-owned subsidiary of Sand Hill and the separate corporate existence of Sand Hill Merger Corp. shall cease. It is expected that holders of St. Bernard common stock will hold approximately 65.6% of the outstanding shares of Sand Hill common stock immediately following the closing of the merger, based on the number of shares of Sand Hill and St. Bernard common stock outstanding as of October 26, 2005. In the merger, Sand Hill will issue a combination of shares of common stock, replacement options and replacement warrants to holders of St. Bernard common stock, options and warrants. The total amount of shares of Sand Hill common stock to be issued or that will underlie replacement options and replacement warrants is 10,880,000. Holders of St. Bernard common stock, options and warrants are entitled to receive their pro rata portion of this 10,880,000 figure. This results in an exchange ratio of 0.421419 shares of Sand Hill common stock, replacement options or replacement warrants for each share of St. Bernard common stock or options or warrants to purchase St. Bernard common stock outstanding. Based upon the number of shares of St. Bernard common stock outstanding and the number of shares issuable for St. Bernard common stock pursuant to outstanding options and warrants as of October 26, 2005, Sand Hill will issue approximately 9,759,600 shares of common stock at the close of the merger. The holders of options and warrants to purchase shares of the common stock of St. Bernard will receive, in exchange for those options and warrants, replacement options and replacement warrants to purchase approximately 1,120,400 shares of Sand Hill common stock. To the extent that outstanding St. Bernard options or warrants are exercised prior to the closing of the merger, the number of shares of Sand Hill common stock that would be issued at the closing of the merger would increase and the number of the shares of Sand Hill common stock that would be subject to replacement options or replacement warrants to be issued at the closing of the merger would decrease by a like amount. For a complete description of the post-closing fully diluted capitalization of Sand Hill please see “Beneficial Ownership of Securities” on page _____.

Sand Hill and St. Bernard plan to complete the merger promptly after the special meetings, provided that:

•	Sand Hill’s and St. Bernard’s stockholders have adopted the merger agreement;

•	holders of less than 20% of the shares of common stock issued in Sand Hill’s initial public offering vote against the merger proposal and demand conversion of their shares of common stock into cash; and

•	the other conditions specified in the merger agreement have been satisfied or waived.

If the Sand Hill stockholder approval has not been obtained at that time or any other conditions have not been satisfied or waived, the merger will be completed promptly after the Sand Hill stockholder approval is obtained or the remaining conditions are satisfied or waived. The merger will become effective when the articles of merger are filed with the Delaware Secretary of State or at such later time as is specified in the articles of merger.

The merger agreement is included as Annex A to this document. We encourage you to read the merger agreement in its entirety. See “The Merger Agreement” on page ___.

Conversion Rights

Pursuant to Sand Hill’s certificate of incorporation, a holder of shares of Sand Hill’s common stock issued in its initial public offering may, if the stockholder votes against the merger, demand that Sand Hill convert such shares into cash. This demand must be made on the proxy card or by telephone or through the Internet as described on the proxy card at the same time that the stockholder votes against the merger proposal. If so demanded, Sand Hill will convert each share of common stock into a pro rata portion of the trust account in which a substantial portion of the net proceeds of Sand Hill’s initial public offering are held, plus all interest earned thereon. If you exercise your conversion rights, then you will be exchanging your shares of Sand Hill common stock for cash and will no longer own these shares. You will only be entitled to receive cash for these shares if you continue to hold these shares through the effective time of the merger and then tender your stock certificate to the combined company. If the merger is not completed, then these shares will not be converted into cash at this time and Sand Hill will need to liquidate if a business combination is not completed by July 27, 2006. Shares that are not voted or are broker non-voted or where the stockholder abstains from voting shall not in any event be eligible to be converted into cash upon completion of the merger.

The merger will not be consummated if the holders of 20% or more of the shares of common stock issued in Sand Hill’s initial public offering exercise their conversion rights.

Appraisal or Dissenters Rights

No appraisal rights or dissenters rights are available under the Delaware General Corporation Law for the stockholders of Sand Hill in connection with the merger proposal.

The total of these shares represented approximately 19.6% of Sand Hill’s issued and outstanding common stock as of the record date. In connection with its initial public offering, the holders of these shares entered into letter agreements with Sand Hill, pursuant to which each agreed to vote their shares of Sand Hill common stock purchased prior to the initial public offering on the merger proposal in the same manner as how a majority of the shares of common stock held by all other Sand Hill stockholders are voted on the merger proposal. They are entitled to vote the shares acquired by them in or subsequent to the initial public offering as they see fit and have indicated that they will vote any shares acquired by them in or subsequent to the initial public offering in favor of the merger proposal. As of March 10, 2006, none of the officers or directors of Sand Hill had acquired any shares of common stock in or subsequent to the initial public offering. Based solely upon information contained in public filings, as of March 10, 2006, the following stockholders beneficially owned greater than five percent of Sand Hill’s issued and outstanding common stock:

•	Amaranth, LLC beneficially owned 287,098 shares of Sand Hill common stock, representing approximately 5.6% of the shares of Sand Hill common stock outstanding on the Sand Hill record date.

On the record date, directors and executive officers of St. Bernard and their affiliates beneficially owned and were entitled to vote approximately 11,529,115 shares of St. Bernard common stock that have a market value of approximately $14,411,394 based on the per share value of St. Bernard’s common stock as of December 31, 2005. The total of these shares represented approximately 49.7% of St. Bernard’s issued and outstanding common stock as of the record date. Based solely upon St. Bernard’s records, as of December 31, 2005, the following stockholders beneficially owned greater than five percent of St. Bernard’s issued and outstanding common stock:

•	Bob Crowe beneficially owned 970,053 shares of St. Bernard common stock, representing approximately 4.2% of the St. Bernard common stock outstanding on the record date; and

•	Bart van Hedel and affiliates beneficially owned 6,705,801 shares of St. Bernard common stock, representing approximately 28.9% of the St. Bernard common stock outstanding on the record date.

Interests of Sand Hill Directors and Officers in the Merger

When you consider the recommendation of Sand Hill’s board of directors that you vote in favor of adoption of the merger proposal, you should keep in mind that a number of Sand Hill’s executives and members of Sand Hill’s board have interests in the merger that are different from, or in addition to, your interests as a Sand Hill or St. Bernard stockholder. These interests include, among other things:

•

if the merger is not approved and Sand Hill fails to consummate an alternative transaction within the time allotted pursuant to its certificate of incorporation and Sand Hill is therefore required to liquidate, the shares of common stock purchased prior to its initial public offering and held by Sand Hill’s executives and directors may be worthless because Sand Hill’s executives and directors are not entitled to receive any of the net proceeds of Sand Hill’s initial public offering that may be distributed upon liquidation of Sand Hill with respect to these shares. In addition, the warrants held by such persons, which as of March 10, 2006 are exercisable for 296,500 shares of common stock (108,500 of which are held by Mr. Polanen), will expire without value in the event of a liquidation;

•	after the completion of the merger, Humphrey P. Polanen will remain as the chairman of the board of directors of the combined company and Scott R. Broomfield will remain as a director of the combined company; and

•

if Sand Hill liquidates prior to the consummation of a business combination, Humphrey P. Polanen, chairman of the board and chief executive officer, will be personally liable to pay debts and obligations, if any, to vendors and other entities that are owed money by Sand Hill for services rendered or products sold to Sand Hill in excess of the net proceeds of Sand Hill’s initial public offering not held in the trust account. As of the date of this joint proxy statement/prospectus such amounts are estimated to be approximately $400,000 at the closing of the merger.

Interests of Officers and Directors of St. Bernard in the Merger

You should understand that some of the current officers and directors of St. Bernard have interests in the merger that are different from, or in addition to, your interest as a Sand Hill or St. Bernard stockholder. These interests include, among other things:

•

After the completion of the merger, several of the present directors of St. Bernard, specifically, Messrs. John E. Jones, Bart van Hedel and a third person yet to be named will remain as directors of the combined company;

•

After the completion of the merger, the current officers of St. Bernard will remain as officers of the combined company; and

•

The directors and executive officers of St. Bernard hold stock options granted to them under various St. Bernard Stock Option Plans. Under the terms of the merger agreement, at the effective time of the merger, each outstanding option to purchase shares of St. Bernard common stock that has been granted under St. Bernard’s 1992, 2000 and 2005 Stock Option Plans, whether vested or unvested, will be fully accelerated pursuant to its terms, and assumed by Sand Hill and become an option to acquire, on the same terms and conditions as were applicable under the applicable stock option plan immediately prior to the effective time of the merger, an option to purchase shares of Sand Hill common stock. The number of shares of Sand Hill common stock for which each option will be exercisable will be determined by multiplying the number of shares of St. Bernard common stock for which such option was exercisable by a conversion ratio of 0.421419. The exercise price per share of Sand Hill common stock at which each such option will be exercisable will be determined by dividing the exercise price per share of St. Bernard common stock at which such option was exercisable by the conversion ratio of 0.421419.

The table below sets forth, as of December 31, 2005, information with respect to options under the 1992 Stock Option Plan, 2000 Stock Option Plan and 2005 Stock Option Plan held by each of St. Bernard’s current executive officers and directors.

STOCK OPTIONS ISSUED TO OFFICERS AND DIRECTORS OF ST. BERNARD SOFTWARE¹

¹ The table sets forth the aggregate total number of options granted by St. Bernard to the individuals listed. Each of the individuals listed received multiple option grants from St. Bernard, at various exercise prices depending on the date of grant. The exercise prices for the option grants range from $0.11 per share to $0.50 per share.

We cannot assure you that all of the conditions will be satisfied or waived or that the merger will occur.

No Solicitation

The merger agreement contains detailed provisions prohibiting each of St. Bernard and Sand Hill from seeking an alternative transaction. The no solicitation covenant of St. Bernard generally prohibits St. Bernard, as well as its officers, directors, employees, representatives or agents, from taking any action to solicit an acquisition proposal as described on pages 42-43 of the merger agreement. The merger agreement does not, however, prohibit St. Bernard from considering a superior proposal from a third party in the circumstances described under “The Merger Agreement—No Solicitation by St. Bernard” on page ___. The no solicitation covenant of Sand Hill generally prohibits Sand Hill, as well as its stockholders, officers, directors, employees, representatives or agents, from taking any action to solicit an acquisition proposal as described on pages 46-47 of the merger agreement. The merger agreement does not, however, prohibit Sand Hill from engaging in discussions or issuing indications of interest to parties in the IT security industry under certain conditions, as long as Sand Hill does not enter into or negotiate the terms of a letter of intent or similar agreement related to a business combination until after certain conditions have been met as described under “The Merger Agreement - No Solicitation by Sand Hill” on page _____.

Termination by St. Bernard

Termination Fee; Expenses

St. Bernard has agreed to pay Sand Hill a termination fee of $1,750,000, net of any expenses already reimbursed by St. Bernard to Sand Hill if the merger agreement is terminated by Sand Hill for specified reasons and St. Bernard completes an alternative acquisition proposal within one year of that termination. Each of Sand Hill and St. Bernard has agreed to pay the expenses of the other incurred in connection with the merger agreement, up to $300,000, if the merger agreement is terminated in the circumstances described under the “The Merger Agreement—Termination Fee and Expenses” on page ____ hereof.

Quotation or Listing

Sand Hill’s outstanding common stock, warrants and units are currently quoted on the Over-the-Counter Bulletin Board. Sand Hill will use its best efforts to cause its outstanding shares of common stock and warrants and the shares of common stock to be issued in the merger to be approved for quotation on the Nasdaq Stock Market or, if they are not eligible for quotation on Nasdaq, to be listed on the American Stock Exchange, prior to the consummation of the merger.

Amendment and Restatement of Sand Hill Certificate of Incorporation

As part of the merger agreement Sand Hill agreed to amend and restate the Sand Hill certificate of incorporation to, among other things, remove the provisions related to the protective provisions related to a business combination put in place when Sand Hill completed its initial public offering as a result of Sand Hill being a Targeted Acquisition Corporation. The amended and restated Sand Hill certificate of incorporation is attached to this document as Annex B. The changes to the Sand Hill certificate of incorporation will not be effective unless the merger is completed.

Officers and Directors After the Merger

The combined company will be managed by the current management of St. Bernard. John E. Jones, who is currently the President and Chief Executive Officer of St. Bernard, will become the President and Chief Executive Officer of the combined company. Alfred Riedler, who is currently the Chief Financial Officer of St. Bernard, will become the Chief Financial Officer of the combined company. Bart van Hedel, who is currently on the board of directors of St. Bernard, will continue as a board member of the combined company. Humphrey P. Polanen, who is currently the Chairman of the Board and Chief Executive Officer of Sand Hill, will continue as Chairman of the Board of the combined company. Scott R. Broomfield, who is currently the Executive Vice President of Corporate Development and on the board of directors of Sand Hill, will continue as a board member of the combined company. Sand Hill and St. Bernard will agree on who the other members of the board of directors of the combined company will be prior to the effective time of the merger.

Indemnification and Stock Escrow Agreement

At the time of the consummation of the merger, Sand Hill will deposit with a mutually acceptable escrow agent ten percent (10%) of the shares of common stock of Sand Hill to be issued in the merger. If, within 270 days of the date of the consummation of the merger, Sand Hill asserts a claim that St. Bernard breached any representation or warranty in the merger agreement, or covenant requiring performance prior to the consummation of the merger, then, subject to the resolution or arbitration of such claim in favor of Sand Hill, the escrow agent will return to Sand Hill a portion of the shares of Sand Hill common stock held in escrow with a value equal to the damages caused by such breach, up to a maximum of the total number of shares of Sand Hill common stock held in escrow. The number of shares to be returned will be based on a per share price of $5.10. The escrowed shares will only be available to satisfy Sand Hill claims that are made within 270 days after the completion of the merger. Two hundred seventy days after completion of the merger any remaining escrowed shares that have not been used to satisfy indemnification claims by Sand Hill will be released to the former stockholders of St. Bernard. The complete text of the stock escrow agreement that will govern these matters is attached as Exhibit E of Annex A. We encourage all stockholders to read the stock escrow agreement in its entirety.

Material United States Federal Income Tax Consequences of the Merger

The merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code.

A St. Bernard stockholder’s receipt of Sand Hill common stock in the merger will be tax-free for United States federal income tax purposes. The receipt in the merger of warrants or options to purchase common stock of Sand Hill by a holder of St. Bernard warrants or options to purchase St. Bernard common stock will be tax-free for United States federal income tax purposes. However, an St. Bernard stockholder who exercises his or her appraisal rights and who receives cash in exchange for his or her shares of St. Bernard common stock generally will recognize gain or loss measured by the difference between the amount of cash received and the tax basis of such stockholders shares of St. Bernard common stock.

A stockholder of Sand Hill who exercises conversion rights and effects a termination of the stockholder’s interest in Sand Hill will generally be required to recognize capital gain or loss upon the exchange of that stockholder’s shares of common stock of Sand Hill for cash, if such shares were held as a capital asset on the date of the merger. Such gain or loss will be measured by the difference between the amount of cash received and the tax basis of that stockholder’s shares of Sand Hill common stock. No gain or loss will be recognized by non-converting stockholders of Sand Hill.

No gain or loss will be recognized by Sand Hill or St. Bernard as a result of the merger. For a description of the material federal income tax consequences of the merger, please see the information set forth in “Material Federal Income Tax Consequences of the Merger” on page ___.

Accounting Treatment

The merger will be accounted for under the reverse acquisition application of the equity recapitalization method of accounting in accordance with U.S. generally accepted accounting principles for accounting and financial reporting purposes. Under this method of accounting, Sand Hill will be treated as the “acquired” company for financial reporting purposes. In accordance with guidance applicable to these circumstances, the merger will be considered to be a capital transaction in substance. Accordingly, for accounting purposes, the merger will be treated as the equivalent of St. Bernard issuing stock for the net monetary assets of Sand Hill, accompanied by a recapitalization. The net monetary assets of Sand Hill will be stated at their fair value, essentially equivalent to historical costs, with no goodwill or other intangible assets recorded. The accumulated deficit of St. Bernard will be carried forward after the merger. Operations prior to the merger will be those of St. Bernard and subsequent to the merger will be those of the combined company.

Regulatory Matters

The merger and the transactions contemplated by the merger agreement are not subject to any federal or state regulatory requirement or approval, including the Hart-Scott-Rodino Antitrust Improvements Act of 1976, or HSR Act, except for filings necessary to effectuate the transactions contemplated by the merger proposal with the Secretary of State of the State of Delaware.

SELECTED UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

The merger will be accounted for as a reverse acquisition application of the equity recapitalization method of accounting. Accordingly, although the merger is structured such that St. Bernard will become a wholly-owned subsidiary of Sand Hill at closing, St. Bernard will be treated as the acquirer for accounting and financial reporting purposes. The assets and liabilities of Sand Hill will be recorded, as of completion of the merger, at their respective historical cost, which is considered to be the equivalent of fair value and added to those of St. Bernard. For a more detailed description of purchase accounting, see “The Merger Proposal—Anticipated Accounting Treatment” on page ___.

We have presented below selected unaudited pro forma combined financial information that reflects the equity recapitalization method of accounting and is intended to provide you with a better picture of what our business might have looked like had St. Bernard and Sand Hill actually combined. The combined financial information may have been different had the companies actually been combined. The selected unaudited pro forma combined financial information does not reflect the effect of asset dispositions, if any, or cost savings that may result from the merger. You should not rely on the selected unaudited pro forma combined financial information as being indicative of the historical results that would have occurred had the companies been combined or the future results that may be achieved after the merger.

RISK FACTORS

You should carefully consider the following risk factors, together with all of the other information included in this joint proxy statement/prospectus, before you decide whether to vote or instruct your vote to be cast to adopt the merger proposal, the stock option plans proposal and the adjournment proposal.

Risks Related to St. Bernard’s Business

Because St. Bernard derives a majority of its license revenue from sales of a few product lines, any decline in demand for these products could severely harm its ability to generate revenue and its results of operations.

St. Bernard derives a majority of its revenue from a small number of software products, including its iPrism, ePrism, Update Expert and Open File Manager and related subscription and maintenance services. In particular, St. Bernard’s future success depends in part on achieving substantial revenue from customer renewals for subscriptions. St. Bernard’s customers have no obligation to renew their subscriptions upon expiration. If St. Bernard’s products fail to meet the needs of its existing and target customers, or if they do not compare favorably in price and performance to competing products, St. Bernard’s growth will be limited. Subscriptions typically have durations of 12, 24 or 36 months. As a result, a majority of the revenue it reports in each quarter is deferred revenue from subscription agreements entered into and paid for during previous quarters. Because of this financial model, the revenue it reports in any quarter or series of quarters may mask significant downturns in sales and the market acceptance of its products. In addition, its products are concentrated on the small and medium enterprise, or SME, environment. St. Bernard is particularly vulnerable to fluctuations in demand for these products, whether as a result of competition, product obsolescence, technological change, budget constraints of its potential customers or other factors. If St. Bernard’s revenue derived from these software products were to decline significantly, including as a result of customers not renewing subscriptions, its business and operating results would be adversely affected.

St. Bernard has a history of losses and negative cash flow and there can be no assurance that St. Bernard will become profitable or achieve consistently positive cash flow.

St. Bernard has a history of operating losses and negative cash flow. As of December 31, 2005, St. Bernard had an accumulated deficit of approximately $29.0 million. There can be no assurance that St. Bernard will achieve profitability and that losses will not occur or that it will not have negative cash flow in the future.

If St. Bernard fails to manage its direct sales and OEM distribution channels effectively its sales could decline.

St. Bernard markets its products and related services both directly to end-users and through a variety of indirect sales channels, which include VARs, distributors, system integrators and OEMs.

Direct Sales. A significant portion of St. Bernard’s revenue is derived from sales by its direct sales force to end-users. This sales channel involves a number of special risks, including:

·	longer sales cycles associated with direct sales efforts;

·	difficulty in hiring, training, retaining and motivating a direct sales force; and

·	the requirement of a substantial amount of training for sales representatives to become productive, and training that must be updated to cover new and revised products.

OEMs. A portion of St. Bernard’s revenue is derived from sales through its OEM partners that incorporate St. Bernard’s products into their products. St. Bernard’s reliance on this sales channel involves a number of special risks, including:

·	its lack of control over the shipping dates or volume of systems shipped;

·	its OEM partners are not subject to minimum sales requirements or any obligation to market its products to their customers;

·	its OEM partners may terminate or renegotiate their arrangements with St. Bernard and new terms may be less favorable in recognition of its increasingly competitive relationship with certain partners;

·	the development work that St. Bernard must generally undertake under its agreements with its OEM partners may require St. Bernard to invest significant resources and incur significant costs with little or no associated revenue;

·	the time and expense required for the sales and marketing organizations of its OEM partners to become familiar with its products may make it more difficult to introduce those products to the market;

·	St. Bernard’s OEM partners may develop, market and distribute their own products and market and distribute products of St. Bernard’s competitors, which could reduce its sales; and

·	if St. Bernard fails to manage its distribution channels successfully, its distribution channels may conflict with one another or otherwise fail to perform as St. Bernard anticipates, which could reduce its sales and increase its expenses, as well as weaken its competitive position.

If the combined company is unable to maintain and expand, or enter into new, indirect sales channels relationships its operating results would decline.

St. Bernard’s indirect sales channels accounted for approximately 28.9% and 33.4% of its revenue in 2005 and 2004. The combined company intends to continue to rely on St. Bernard’s indirect sales channels for a significant portion of its revenue. St. Bernard depends on its indirect sales channels, including value-added resellers, distributors, and providers of managed Internet services, to offer its products to a larger customer base than can be reached through a direct sales effort. None of these parties is obligated to continue selling St. Bernard’s products or to make any purchases from St. Bernard. If they are unsuccessful in their efforts or are unwilling or unable to market and sell St. Bernard’s new product offerings, St. Bernard’s operating results will suffer. St. Bernard cannot control the level of effort these parties expend or the extent to which any of them will be successful in marketing and selling its products. Some of St. Bernard’s indirect sales channels also market and sell products that compete with its products or may decide to do so in the future. St. Bernard may not be able to prevent these parties from devoting greater resources to support its competitors’ products and/or eliminating their efforts to sell its products.

St. Bernard’s international sales and operations involve special risks that could increase its expenses, adversely affect its operating results and require increased time and attention of its management.

St. Bernard derives less than 10% of its revenue from customers located outside of the U.S. and has operations outside of the U.S., including sales and customer support. The combined company plans to expand St. Bernard’s international operations and St. Bernard’s planned growth is contingent upon the successful expansion of its international revenue. St. Bernard’s international operations are subject to risks in addition to those faced by its domestic operations, including:

·	potential loss of proprietary information due to piracy, misappropriation or laws that may be less protective of St. Bernard’s intellectual property rights than those in the U.S.;

·	imposition of foreign laws and other governmental controls, including trade and employment restrictions;

·	fluctuations in currency exchange rates and economic instability such as higher interest rates and inflation, which could reduce its customers’ ability to obtain financing for software products or which could make its products more expensive in those countries;

·	limitations on future growth or inability to maintain current levels of revenue from international sales if the combined company does not invest sufficiently in its international operations;

·	difficulties in hedging foreign currency transaction exposures;

·	longer payment cycles for sales in foreign countries and difficulties in collecting accounts receivable;

·	difficulties in staffing, managing and operating international operations, including difficulties related to administering stock plans in some foreign countries;

·	difficulties in coordinating the activities of its geographically dispersed and culturally diverse operations;

·	seasonal reductions in business activity in the summer months in Europe and in other periods in other countries;

·	costs and delays associated with developing software in multiple languages; and

·	war or terrorism, particularly in areas in which St. Bernard has facilities.

The market for St. Bernard’s products continues to emerge, and if it is not successful in promoting awareness of the need for its products and of the St. Bernard brand, its growth may be limited.

Based on St. Bernard’s experience with potential customers, St. Bernard believes that many corporations do not recognize or acknowledge the existence or scope of problems caused by misuse or abuse of the Internet or of network computers, creating significant barriers to sales. In addition, there may be a time-limited opportunity to achieve and maintain a significant share of the market for web filtering and email filtering and St. Bernard’s other products due in part to the emerging nature of these markets and the substantial resources available to its existing and potential competitors. If companies do not recognize or acknowledge these problems, then the market for St. Bernard’s products may develop more slowly than it expects, which could adversely affect its operating results. Developing and maintaining awareness of the St. Bernard brand is critical to achieving widespread acceptance of St. Bernard’s existing and future products. Furthermore, St. Bernard believes that the importance of brand recognition will increase as competition in its market develops. Successful promotion of the St. Bernard brand will depend largely on the effectiveness of the combined company’s marketing efforts and on its ability to develop reliable and useful products at competitive prices. If the combined company fails to successfully promote the St. Bernard brand, or if its expenses to promote and maintain the St. Bernard brand are greater than anticipated, its results of operations and financial condition could suffer.

If the combined company is not able to develop new and enhanced products that achieve widespread market acceptance, it may be unable to recover product development costs, and its earnings and revenue may decline.

St. Bernard’s future success depends on its ability to address the rapidly changing needs of its customers by developing, acquiring and introducing new products, product updates and services on a timely basis. St. Bernard must also extend the operation of its products to new platforms and keep pace with technological developments and emerging industry standards. The combined company intends to commit substantial resources to developing new software products and services, including software products and services for the secure content management small and medium enterprise market. Products being developed are new and unproven, and industry standards for these markets are evolving and changing. They also may require development of new sales channels. If these markets do not develop as anticipated, or if demand for its products and services in these markets does not materialize or occurs more slowly than St. Bernard expects, the combined company will have expended substantial resources and capital without realizing sufficient revenue, and its business and operating results could be adversely affected.

St. Bernard incurs considerable expenses to develop products for operating systems that are either owned by others or that are part of the Open Source Community. If it does not receive cooperation in its development efforts from others and access to operating system technologies, St. Bernard may face higher expenses or fail to expand its product lines and revenues.

Many of St. Bernard’s products operate primarily on the Linux, UNIX and Windows computer operating systems. As part of St. Bernard’s efforts to develop products for operating systems that are part of the Open Source Community, St. Bernard may have to license portions of its products on a royalty free basis or may have to expose its source code. Open Source describes general practices in production and development which promote access to the end product’s sources. The Open Source Community emphasizes collaborative development and requires licensing that allows modifications and enhancements of registered open source code be made available to whoever would like to use it. Developers who use open source code in proprietary products risk exposing the intellectual property developed in conjunction with the open source code to the public. St. Bernard continues to develop new products for these operating systems. It may not accomplish its development efforts quickly or cost-effectively, and it is not clear what the relative growth rates of these operating systems will be. St. Bernard’s development efforts require substantial capital investment, the devotion of substantial employee resources and the cooperation of the owners of the operating systems to or for which the products are being ported or developed. If the market for a particular operating system does not develop as anticipated, or demand for St. Bernard’s products and services in such market does not materialize or occurs more slowly than it expects, the combined company may have expended substantial resources and capital without realizing sufficient revenue, and its business and operating results could be adversely affected.

In addition, for some operating systems, St. Bernard must obtain from the owner of the operating system a source code license to portions of the operating system software to port some of its products to or develop products for the operating system. Operating system owners have no obligation to assist in these porting or development efforts. If they do not grant St. Bernard a license or if they do not renew its license, St. Bernard may not be able to expand its product lines into other areas.

St. Bernard faces increasing competition, which places pressure on its pricing and which could prevent St. Bernard from increasing revenue or maintaining profitability. In addition, St. Bernard may face competition from better-established companies that have significantly greater resources.

The market for St. Bernard’s products is intensely competitive and is likely to become even more so in the future. St. Bernard’s current principal competitors frequently offer their products at a significantly lower price than St. Bernard’s products, which has resulted in pricing pressures on sales of St. Bernard’s products. St. Bernard also faces increasing competition from security solutions providers who may add security modules or features to their product offerings. In addition, pricing pressures and increased competition generally could result in reduced sales, reduced margins or the failure of St. Bernard’s products to achieve or maintain more widespread market acceptance, any of which could have a material adverse effect on its business, results of operations and financial condition.

St. Bernard also faces current and potential competition from vendors of operating systems and networking hardware, many of which now, or may in the future, develop and/or bundle security, file backup, patch management or other competitive products with their products. St. Bernard competes against, and expects increased competition from, anti-virus software developers, traditional network management software developers and Web management service providers. If security or file backup functions become standard features of internet-related hardware or software, the demand for St. Bernard’s products will decrease. Furthermore, even if St. Bernard’s products provide greater functionality and are more effective than certain other competitive products, potential customers might accept limited functionality as part of an unbundled solution in lieu of purchasing separate products which require more administration. In addition, St. Bernard’s own indirect sales channels may decide to develop or sell competing products instead of its products. Many of St. Bernard’s potential competitors have substantial competitive advantages, such as:

·	greater name recognition and larger marketing budgets and resources;

·	established marketing relationships and access to larger customer bases; and

·	substantially greater financial, technical and other resources.

As a result, they may be able to respond more quickly and effectively than St. Bernard can to new or changing opportunities, technologies, standards or customer requirements. For all of the foregoing reasons, the combined company may not be able to compete successfully against St. Bernard’s current and future competitors, and its results of operations could be adversely affected.

St. Bernard’s database categories and its process for classifying websites and software applications within those categories are subjective, and it may not be able to categorize websites and software applications in accordance with its customers’ expectations.

St. Bernard may not succeed in accurately categorizing Internet and application content to meet its customers’ expectations. St. Bernard relies upon a combination of automated filtering technology and human review to categorize websites and software applications in its proprietary databases. St. Bernard’s customers may not agree with its determinations that particular websites and software applications should be included or not included in specific categories of its databases. In addition, it is possible that the filtering processes may place objectionable material in categories that are generally unrestricted by St. Bernard’s users’ Internet and computer access policies, which could result in employees having access to such material in the workplace. Any miscategorization could result in customer dissatisfaction and harm St. Bernard’s reputation. Furthermore, St. Bernard selects its categories based on content it believes employers want to manage. St. Bernard may not now, or in the future, succeed in properly identifying the categories of content that employers want to manage. Any failure to effectively categorize and filter websites and software applications according to its customers’ expectations will impair the growth of St. Bernard’s business and its efforts to increase brand acceptance.

St. Bernard’s databases may fail to keep pace with the rapid growth and technological change of the Internet.

The success of St. Bernard’s products depends, in part, on the breadth and accuracy of its databases. Although its databases currently catalog more than six million websites, they contain only a portion of such material that exists. In addition, the total number of websites is growing rapidly, and St. Bernard expects this rapid growth rate to continue in the future. St. Bernard’s databases and database technologies may not be able to keep pace with the growth in the number of websites and software applications, especially the growing amount of content utilizing foreign languages. Further, the ongoing evolution of the Internet and computing environments will require it to continually improve the functionality, features and reliability of its databases. Because its products primarily can only manage access to websites included in its databases, if St. Bernard’s databases do not contain a meaningful portion of relevant content, the effectiveness of iPrism and ePrism will be significantly diminished. Any failure of St. Bernard’s databases to keep pace with the rapid growth and technological change of the Internet will impair the market acceptance of its products, which in turn will harm its business, results of operations and financial condition.

The combined company’s business strategy includes possible growth through acquisitions, which involve special risks that could increase the combined company’s expenses, and divert the time and attention of management.

As part of its business strategy, St. Bernard has in the past acquired product, technology and companies and the combined company expects in the future to acquire other businesses, business units and technologies. Acquisitions involve a number of special risks and challenges, including:

·	diversion of management’s attention from St. Bernard’s business;

·	integration of acquired business operations and employees into its existing business, including coordination of geographically dispersed operations, which can take longer and be more complex than initially expected;

·	incorporation of acquired products and business technologies into existing product lines, including consolidating technology with duplicative functionality or designed on different technological architecture, and the ability to sell the acquired products through existing or acquired sales channels;

·	loss or termination of employees, including costs associated with the termination of those employees;

·	dilution of then-current stockholders’ percentage ownership;

·	dilution of earnings if synergies with the acquired businesses are not achieved;

·	inability to generate sufficient revenue to offset acquisition or investment costs;

·	assumption of liabilities of the acquired businesses, including costly litigation related to alleged liabilities of the acquired businesses;

·	presentation of a unified corporate image to customers and employees;

·	increased costs and efforts in connection with compliance with Section 404 of the Sarbanes-Oxley Act; and

·	risk of impairment charges related to potential write-down of acquired assets in future acquisitions.

Acquisitions of businesses, business units and technologies are inherently risky and create many challenges. The combined company cannot provide any assurance that any future acquisitions will achieve the desired objectives. If the combined company fails to properly evaluate and execute acquisitions or investments, its business and prospectus may be seriously harmed.

St. Bernard’s growth could strain its personnel and infrastructure resources, and if it is unable to implement appropriate controls and procedures to manage its growth, St. Bernard may not be able to successfully implement its business plan.

St. Bernard continues to experience rapid growth in its operations, which has placed, and will continue to place, a significant strain on its management, administrative, operational and financial infrastructure. St. Bernard’s future success will depend in part upon the ability of its senior management to manage growth effectively. This will require the combined company to hire and train additional personnel to manage its expanding operations. In addition, the combined company will be required to continue to improve its operational, financial and management controls and its reporting systems and procedures. If the combined company fails to successfully manage its growth, it will be unable to execute its business plan.

St. Bernard products may contain significant errors and failures, which may subject it to liability for damages suffered by end-users.

Software products frequently contain errors or failures, especially when first introduced or when new versions are released. St. Bernard’s end-user customers use its products in applications that are critical to their businesses, including for data protection and recovery, and may have a greater sensitivity to defects in St. Bernard’s products than to defects in other, less critical software products. If a customer loses critical data as a result of an error in or failure of St. Bernard’s software products or as a result of the customer’s misuse of St. Bernard’s software products, the customer could suffer significant damages and seek to recover those damages from St. Bernard. Although St. Bernard’s software licenses generally contain protective provisions limiting its liability, a court could rule that these provisions are unenforceable. If a customer is successful in proving its damages and a court does not enforce St. Bernard’s protective provisions, St. Bernard could be liable for the damages suffered by its customers and other related expenses, which could adversely affect its operating results.

Product errors or failures could cause delays in new product releases or product upgrades, or St. Bernard’s products might not work in combination with other hardware or software, which could adversely affect market acceptance of St. Bernard’s products. If St. Bernard’s customers were dissatisfied with product functionality or performance, or if St. Bernard were to experience significant delays in the release of new products or new versions of products, it could lose competitive position and revenue and its business and operating results could be adversely affected.

Failure to protect its intellectual property rights could impair St. Bernard’s ability to protect its proprietary technology and establish the St Bernard brand.

Intellectual property is critical to St. Bernard’s success, and it relies upon trademark, copyright and trade secret laws in the United States and other jurisdictions as well as confidentiality procedures and contractual provisions to protect its proprietary technology and the St. Bernard brand. Any of its trademarks may be challenged by others or invalidated through administrative process or litigation. St. Bernard currently has only two issued patents in the United States and one corresponding issued patent internationally, and it may be unable to obtain further patent protection in the future. In addition, any issued patents may not provide St. Bernard with any competitive advantages, or may be challenged by third parties. Furthermore, legal standards relating to the validity, enforceability and scope of protection of intellectual property rights are uncertain. Effective patent, trademark, copyright and trade secret protection may not be available to St. Bernard in every country in which its products are available. The laws of some foreign countries may not be as protective of intellectual property rights as United States laws, and mechanisms for enforcement of intellectual property rights may be inadequate. As a result St. Bernard’s means of protecting its proprietary technology and brands may not be adequate. Furthermore, despite its efforts, St. Bernard may be unable to prevent third parties from infringing upon or misappropriating its intellectual property, including the misappropriation or misuse of the content of its proprietary database of websites. Any such infringement or misappropriation could have a material adverse effect on St. Bernard’s business, results of operations and financial condition.

If St. Bernard is sued by third parties for alleged infringement of their proprietary rights its results of operations could suffer.

The software and internet industries are characterized by the existence of a large number of patents, trademarks and copyrights and by frequent litigation based on allegations of patent infringement or other violations of intellectual property rights. As the number of entrants into St. Bernard’s market increases, the possibility of an intellectual property claim against it grows. St. Bernard’s technologies and products may not be able to withstand any third-party claims or rights against their use. Any intellectual property claims, with or without merit, could be time-consuming and expensive to litigate or settle, and could divert management attention from executing its business plan. There can be no assurance that St. Bernard would be successful in any such suit.

St. Bernard’s systems may be vulnerable to security risks or service disruptions that could harm its business.

Although it has taken measures to secure its systems against security risks and other causes of disruption of electronic services, St. Bernard’s servers are vulnerable to physical or electronic break-ins and service disruptions, which could lead to interruptions, delays, loss of data or the inability to process customer requests. Such events could be very expensive to remedy, could damage St. Bernard’s reputation and could discourage existing and potential customers from using its products.

Evolving regulation of the Internet may affect St. Bernard adversely.

As Internet commerce continues to evolve, increasing regulation by federal, state or foreign agencies becomes more likely. Such regulation is likely in the areas of user privacy, pricing, content and quality of products and services. Taxation of Internet use or other charges imposed by government agencies or by private organizations for accessing the Internet may also be imposed. Laws and regulations applying to the solicitation, collection or processing of personal or consumer information could affect St. Bernard’s activities. Furthermore, any regulation imposing fees for Internet use could result in a decline in the use of the Internet and the viability of Internet commerce, which could have a material adverse effect on St. Bernard’s business, results of operations and financial condition.

The market price of the combined company’s securities is likely to be highly volatile and subject to wide fluctuations.

The market price of Sand Hill’s securities prior to the merger has been and likely will continue to be highly volatile and could be subject to wide fluctuations in response to a number of factors that are beyond its control, including:

·	announcements of technological innovations or new products or services by its competitors;

·	demand for its products, including fluctuations in subscription renewals;

·	fluctuations in revenue from indirect sales channels;

·	changes in the pricing policies of its competitors; and

·	changes in government regulations.

In addition, the market price of the combined company’s securities could be subject to wide fluctuations in response to a number of factors, including:

·	announcements of technological innovations or new products or services by St. Bernard;

·	changes in its pricing policies;

·	quarterly variations in its revenues and operating expenses; and

·	its technological capabilities to accommodate the future growth in its operations or its customers.

Further, the stock market has experienced significant price and volume fluctuations that have particularly affected the market price of the stock of many Internet-related companies, and that often have been unrelated or disproportionate to the operating performance of these companies. A number of publicly traded Internet-related companies have current market prices below their initial public offering prices. Market fluctuations such as these may seriously harm the market price of the combined company’s securities. In the past, securities class action suits have been filed following periods of market volatility in the price of a company’s securities. If such an action were instituted, the combined company would incur substantial costs and a diversion of management attention and resources, which would seriously harm its business, results of operations and financial condition.

Risks Related to the Merger

If 20% or more of the holders of Sand Hill’s public securities decide to vote against the proposed acquisition, Sand Hill may be forced to liquidate, stockholders may receive less than $6.00 per share and the warrants may expire worthless.

Under the terms of Sand Hill’s certificate of incorporation, if 20% or more of the shares issued in Sand Hill’s initial public offering decide to vote against the merger and opt to convert their shares to cash, Sand Hill will be unable to complete the merger and may be ultimately forced to liquidate. While Sand Hill will continue to search to acquire an operating company in the IT security industry, if it does not consummate a business combination by July 27, 2006, it will be forced to liquidate. In any liquidation, the net proceeds of Sand Hill’s initial public offering held in the trust account, plus any interest earned thereon, will be distributed pro rata to the holders of Sand Hill’s common stock issued in its initial public offering. If Sand Hill is forced to liquidate its assets, the per-share liquidation to such stockholders will be approximately $5.25, plus interest accrued thereon until the date of any liquidation, as of October 26, 2005. Furthermore, there will be no distribution with respect to Sand Hill’s outstanding warrants and, accordingly, the warrants will expire worthless.

The combined company’s working capital could be reduced, and Sand Hill stockholders could own less than 34.4% of the combined company’s outstanding common stock, if Sand Hill stockholders exercise their right to convert their shares into cash.

Pursuant to Sand Hill’s certificate of incorporation, holders of shares issued in Sand Hill’s initial public offering may vote against the merger and demand that Sand Hill convert their shares into cash. Sand Hill and St. Bernard will not consummate the merger if holders of 20% or more shares of common stock issued in Sand Hill’s initial public offering exercise these conversion rights. To the extent the merger is consummated and holders of less than 20% of Sand Hill’s common stock issued in its initial public offering have demanded to convert their shares, there will be a corresponding reduction in the amount of funds available to the combined company following the merger and a reduction in the aggregate percentage of the combined company that is owned by Sand Hill’s stockholders after the merger. Additionally, if holders demand to convert their shares, there may be a corresponding reduction in the value of each share of common stock held in the combined company. As of October 26, 2005, assuming the merger proposal is adopted, the maximum amount of funds that could be disbursed to Sand Hill’s stockholders upon the exercise of the conversion rights is approximately $4,315,500, or approximately 20% of the funds currently held in trust. If the maximum amount of funds were disbursed, the percentage of the combined company’s common stock that would be owned by the Sand Hill stockholders who did not exercise their conversion right would be 30.6%.

A substantial number of the combined company’s shares will become eligible for future resale in the public market after the merger which could result in dilution and an adverse effect on the market price of those shares.

If the merger is consummated, warrants to purchase 8,760,000 shares of common stock issued in connection with the Sand Hill initial public offering will become exercisable on the date the merger is consummated, as described under “Description of Sand Hill’s Securities Following the Merger--Warrants.” Moreover, 1,000,000 shares of Sand Hill common stock purchased by stockholders prior to Sand Hill’s initial public offering will be held in escrow until July 26, 2007, at which time they will be released from escrow and be eligible for resale in the public market subject to compliance with applicable law. Consequently, at various times after completion of the merger, a substantial number of additional shares of Sand Hill common stock will be eligible for resale in the public market. Sales of substantial numbers of such shares in the public market could adversely affect the market price of such shares and of the warrants.

If Sand Hill is unable to receive a listing of its securities on a national securities exchange or NASDAQ, then it may be more difficult for its stockholders to sell their securities.

The listing of the Sand Hill common stock, warrants and units on the Nasdaq Stock Market or on the American Stock Exchange is not a condition to the merger and the possible quotation of Sand Hill’s securities on a national securities exchange or NASDAQ is uncertain. If Sand Hill is unable to receive a listing or approval of trading of its securities on a national securities exchange or NASDAQ, then it may be more difficult for its stockholders to sell their securities. Shares of Sand Hill common stock, warrants and units are currently traded in the over-the-counter market and quoted on the Over-the-Counter Bulletin Board. The merger agreement provides that Sand Hill will file an application to list the shares of Sand Hill common stock and warrants outstanding prior to completion of the merger, as well as all the shares of common stock to be issued in the merger, for listing on the Nasdaq Stock Market or on the American Stock Exchange and will use commercially reasonable efforts to cause such listing to be accomplished as soon as practicable after the date of the merger agreement. There is no assurance that this approval will occur on or prior to consummation of the merger or at all.

Sand Hill directors and executive officers have interests in the merger that are different from yours because if the merger is not approved then the shares held by them may become worthless.

In considering the recommendation of the board of directors of Sand Hill to vote for the proposal to adopt the merger agreement you should be aware that a number of Sand Hill’s executives and members of Sand Hill’s board have interests in the merger that are different from, or in addition to, your interests as a stockholder. These interests include, among other things:

•

if the merger is not approved and Sand Hill fails to consummate an alternative transaction within the time allotted pursuant to its certificate of incorporation and Sand Hill is therefore required to liquidate, the shares of common stock purchased prior to its initial public offering and held by Sand Hill’s executives and directors may be worthless because Sand Hill’s executives and directors are not entitled to receive any of the net proceeds of Sand Hill’s initial public offering that may be distributed upon liquidation of Sand Hill with respect to these shares. In addition, the warrants held by such persons, which as of March 10, 2006 are exercisable for 296,500 shares of common stock (108,500 of which are held by Mr. Polanen) will expire without value in the event of a liquidation;

•	after the completion of the merger, Humphrey P. Polanen will remain as the chairman of the board of directors of the combined company and Scott R. Broomfield will remain as a director of the combined company; and

•

The amount of stock held by executive officers, directors and other affiliates of the combined company may limit your ability to influence the outcome of director elections and other matters requiring stockholder approval.

Upon consummation of the merger, executive officers, directors and affiliates of the combined company will own approximately 38.5% of the combined company’s voting stock. These stockholders can have a substantial influence on all matters requiring approval by our stockholders, including the election of directors and the approval of mergers or other business combination transactions. This concentration of ownership could have the effect of delaying or preventing a change in our control or discouraging a potential acquiror from attempting to obtain control of us, which in turn could have a material adverse effect on the market price of the common stock or prevent our stockholders from realizing a premium over the market price for their shares of common stock.

The lack of diversification in the business of the combined company affects Sand Hill’s ability to mitigate the risks that it may face or to offset possible losses that it may incur as a result of competing in the IT security industry.

The prospects for Sand Hill’s success will be entirely dependent upon the future performance of a single business. Sand Hill will not have the resources to diversify its operations or benefit from the possible spreading of risks or offsetting of losses. By consummating a business combination with only a single entity, Sand Hill’s lack of diversification may subject Sand Hill to numerous economic, competitive and regulatory developments, any or all of which may have a substantial adverse impact upon the particular industry in which Sand Hill operates subsequent to the business combination, and result in Sand Hill’s dependency upon the development or market acceptance of a single or limited number of products, processes or services.

If you do not vote your shares at the Sand Hill special meeting or give instructions to your broker to vote or abstain from voting you will not be eligible to convert your shares of Sand Hill common stock into cash and receive a portion of the trust fund upon consummation of the merger.

Record Date; Who is Entitled to Vote

The record date for the Sand Hill special meeting is ___________, 2006. Record holders of Sand Hill common stock at the close of business on the record date are entitled to vote or have their votes cast at the Sand Hill special meeting. On the record date, there were 5,110,000 outstanding shares of Sand Hill common stock.

Each share of Sand Hill common stock is entitled to one vote per share at the Sand Hill special meeting.

Pursuant to letter agreements with Sand Hill, any shares of Sand Hill common stock held by stockholders who purchased their shares of common stock prior to Sand Hill’s initial public offering will be voted on the merger proposal in the same manner as how the majority of the shares of common stock held by all other Sand Hill stockholders are voted on the merger proposal. The holders of such common stock are free to vote their shares acquired in Sand Hill’s initial public offering or afterwards as they see fit and are free to vote all of their common stock, however obtained, on the other proposals as they see fit.

Sand Hill’s issued and outstanding warrants do not have voting rights and record holders of Sand Hill warrants will not be entitled to vote at the Sand Hill special meeting.

Quorum

The presence, in person or by proxy, of a majority of all the outstanding shares of Sand Hill common stock constitutes a quorum at the special meeting. Abstentions and broker non-votes will count as present for purposes of establishing a quorum.

Voting Your Shares

Each share of Sand Hill common stock that you own in your name entitles you to one vote. Your proxy card shows the number of shares of Sand Hill common stock that you own.

There are three ways to vote your shares of Sand Hill common stock at the Sand Hill special meeting:

•

You can vote by signing and returning the enclosed proxy card. If you vote by proxy card, your “proxy,” whose name is listed on the proxy card, will vote your shares as you instruct on the proxy card. If you sign and return the proxy card but do not give instructions on how to vote your shares, your shares will be voted as recommended by the Sand Hill board “FOR” the adoption of the merger proposal, the amendment proposal, the stock option plans proposal and the adjournment proposal.

•

You can vote by telephone or on the Internet by following the telephone or Internet voting instructions that are included with your proxy card. If you vote by telephone or by the Internet, you should not return the proxy card. The deadline for voting by telephone or electronically is 11:59 p.m., Eastern Standard Time, on _______________, 2006.

•

You can attend the Sand Hill special meeting and vote in person. We will give you a ballot when you arrive. However, if your shares are held in the name of your broker, bank or another nominee, you must get a proxy from the broker, bank or other nominee. That is the only way we can be sure that the broker, bank or nominee has not already voted your shares.

IF YOU DO NOT VOTE YOUR SHARES OF SAND HILL COMMON STOCK IN ANY OF THE WAYS DESCRIBED ABOVE, IT WILL HAVE THE SAME EFFECT AS A VOTE AGAINST THE ADOPTION OF THE MERGER PROPOSAL, BUT WILL NOT HAVE THE EFFECT OF A DEMAND OF CONVERSION OF YOUR SHARES INTO CASH.

Who Can Answer Your Questions About Voting Your Shares

If you have any questions about how to vote or direct a vote in respect of your Sand Hill common stock, you may call Humphrey P. Polanen, Sand Hill’s chairman and chief executive officer, at (650) 926-7022.

No Additional Matters May Be Presented at the Sand Hill Special Meeting

The Sand Hill special meeting has been called only to consider the adoption of the merger proposal, the amendment proposal, the stock option plans proposal and the adjournment proposal. Under Sand Hill’s bylaws, other than procedural matters incident to the conduct of the meeting, no other matters may be considered at the Sand Hill special meeting if they are not included in the notice of the Sand Hill meeting.

Revoking Your Proxy

If you give a proxy, you may revoke it at any time before it is exercised by doing any one of the following:

•	You may send another proxy card with a later date;

•	You may notify Humphrey P. Polanen, Sand Hill’s chairman and chief executive officer, in writing before the Sand Hill special meeting that you have revoked your proxy; or

•	You may attend the Sand Hill special meeting, revoke your proxy, and vote in person.

Vote Required

The adoption of the merger agreement and the transactions contemplated by the merger agreement will require the affirmative vote of the majority of the outstanding shares of Sand Hill common stock on the Sand Hill record date.

The adoption of the amendment and restatement of Sand Hill’s certificate of incorporation will require the affirmative vote of the majority of the outstanding shares of Sand Hill common stock on the Sand Hill record date.

The adoption of the stock option plans proposal will require the affirmative vote of a majority of the shares of Sand Hill common stock present in person or represented by proxy at the Sand Hill special meeting.

The adoption of the adjournment proposal will require the affirmative vote of a majority of the shares of Sand Hill common stock present in person or represented by proxy at the Sand Hill special meeting.

The adoption of the merger proposal is conditioned on the adoption of the amendment proposal and the adoption of the amendment proposal is conditioned on the adoption of the merger proposal. The adoption of neither the merger proposal nor the amendment proposal is conditioned on the adoption of the stock option plans proposal or the adjournment proposal. The adoption of the stock option plans proposal, however, is conditioned upon the adoption of the merger proposal and the amendment proposal.

Abstentions and Broker Non-Votes

If your broker holds your shares in its name and you do not give the broker voting instructions, under the rules of the NASD, your broker may not vote your shares on the proposals to adopt the merger agreement and the amendment and restatement of the Sand Hill certificate of incorporation. If you do not give your broker voting instructions and the broker does not vote your shares, this is referred to as a “broker non-vote.” Abstentions will have the same effect as a vote “against” the merger proposal, the amendment proposal, the stock option plans proposal and the adjournment proposal. Broker non-votes, while considered present for the purposes of establishing a quorum, will have the effect of a vote against the merger proposal and the amendment proposal, but will have no effect on the stock options plan proposal or the adjournment proposal. Shares that are broker non-voted or where the stockholder abstains from voting are not be eligible to be converted into cash upon completion of the merger.

Conversion Rights

Any stockholder of Sand Hill holding shares of common stock issued in Sand Hill’s initial public offering who votes against the merger proposal may, at the same time, demand that Sand Hill convert their shares into a pro rata portion of the trust account holding a substantial portion of the net proceeds of Sand Hill’s initial public offering. If so demanded, Sand Hill will convert these shares into a pro rata portion of the funds held in a trust account, which consist of $21,025,000 of the net proceeds from the initial public offering deposited into the trust account plus interest earned thereon, if the merger is consummated. If the holders of 20%, or 822,000, or more of the shares of common stock issued in Sand Hill’s initial public offering vote against the merger and demand conversion of their shares into a pro rata portion of the trust account, Sand Hill will not be able to consummate the merger and Sand Hill will need to liquidate if a business combination is not completed by July 27, 2006. If you exercise your conversion rights, then you will be exchanging your shares of Sand Hill common stock for cash and will no longer own these shares. You will only be entitled to receive cash for these shares if you continue to hold these shares through the effective time of the merger and then tender your stock certificate to the combined company. The closing price of Sand Hill’s common stock on October 26, 2005 was $5.27 and the amount of cash held in the trust account on that date was $21,565,509.96. If a Sand Hill stockholder would have elected to exercise its conversion rights on such date, then it would have been entitled to receive approximately $5.25 per share, or $0.75 less than the per-unit offering price of $6.00 for which the Sand Hill stockholder purchased units of the initial public offering. Prior to exercising conversion rights, Sand Hill stockholders should verify the market price of Sand Hill’s common stock as they may receive higher proceeds from the sale of their common stock in the public market than from exercising their conversion rights if the market price per share is higher than the conversion price.

Solicitation Costs

Sand Hill is soliciting proxies on behalf of the Sand Hill board of directors. This solicitation is being made by mail but also may be made by telephone or in person. Sand Hill and its respective directors, officers and employees may also solicit proxies in person, by telephone or by other electronic means. These persons will not be paid for doing this. Sand Hill has not hired a firm to assist in the proxy solicitation process but may do so if it deems this assistance necessary. Sand Hill will pay all fees and expenses related to the retention of any proxy solicitation firm.

Sand Hill will ask banks, brokers and other institutions, nominees and fiduciaries to forward its proxy materials to their principals and to obtain their authority to execute proxies and voting instructions. Sand Hill will reimburse them for their reasonable expenses.

Stock Ownership

At the close of business on the record date, Humphrey P. Polanen, Sand Hill Security, LLC, an affiliate of the officers and directors of Sand Hill, Keith Walz, Scott Broomfield, Cary Grossman, Daniel Johnson and Alberto Micalizzi beneficially owned and were entitled to vote approximately 1,000,000 shares of Sand Hill common stock, or approximately 19.6% of the then outstanding shares of Sand Hill common stock, which includes all of the shares held by the directors and executive officers of Sand Hill and their affiliates. These shares have a market value of $5,290,000 based on Sand Hill’s common stock price of $5.29 per share as of December 31, 2005. Those persons, who were stockholders of Sand Hill prior to its initial public offering of securities, have agreed pursuant to letter agreements with Sand Hill to vote their shares of Sand Hill common stock purchased prior to the initial public offering in the same manner as how a majority of the shares of common stock held by all other Sand Hill stockholders are voted on the merger proposal. They are entitled to vote the shares acquired by them in or subsequent to the initial public offering as they see fit and have indicated that they will vote any shares acquired by them in or subsequent to the initial public offering in favor of the merger proposal. As of March 10, 2006, none of the officers or directors of Sand Hill had acquired any shares of common stock in or subsequent to the initial public offering. Mr. Polanen is currently chairman of the board of directors and chief executive officer of Sand Hill. Messrs. Broomfield and Walz are directors and executive officers of Sand Hill and Messrs. Grossman, Johnson and Micalizzi are directors of Sand Hill. In addition, Sand Hill Security, LLC is an affiliate of the directors and officers of Sand Hill and Mr. Polanen is its sole manager. Based solely upon information contained in public filings, as of December 12, 2005, the following stockholders beneficially owned greater than five percent of Sand Hill’s issued and outstanding common stock:

•	Humphrey P. Polanen and his affiliates beneficially owned 559,441 shares of Sand Hill common stock, representing approximately 10.9% of the Sand Hill common stock outstanding on the Sand Hill record date;

•	Sapling, LLC beneficially owned 400,000 shares of Sand Hill common stock, representing approximately 7.8% of the Sand Hill common stock outstanding on the Sand Hill record date;
