BLUELINE PARTNERS, L.L.C.

To our Fellow Stockholders of Criticare Systems, Inc.:

BlueLine Partners, L.L.C. (“BlueLine”) together with its affiliated entities is the largest stockholder of Criticare Systems, Inc. (“Criticare” or the “Company”) and currently hold 1,318,700 shares, or approximately 10.7%, of the Company’s outstanding common stock. BlueLine invests primarily in medical device companies and seeks to invest when it believes a company is undervalued relative to its potential and in a situation where BlueLine’s efforts can help to create or unlock value. BlueLine is a long-term investor that has held shares in Criticare for more than two years. During this time, we have sought to engage with management and members of the Company’s Board of Directors (the “Board”) to provide the Company with perspective from outside the Company and advice on the execution of its business plan and other related issues influencing Criticare’s stock price.

Central to BlueLine’s advice has been the need for Criticare’s Board to become more active and to fulfill its responsibilities in representing the interests of the Company’s stockholders. The Company’s Board has historically been quite passive, rarely holding meetings in person and having at least one committee that — according to the Company’s filings with the Securities and Exchange Commission — has never met. Based upon BlueLine’s experiences with the Company and the Board’s continuing passivity, we question the commitment of the Company’s current directors to take actions that may be necessary to improve the Company’s performance.

BlueLine is therefore asking for your help to re-form the Board and elect a new majority of directors who are independent of management and have the experience and commitment necessary to properly represent the interests of the Company’s stockholders. BlueLine believes it is imperative for the Company’s stockholders to act now to protect their interests and to preserve the current value inherent in the Company’s business.

More than a year ago, the Company launched three major product initiatives with tremendous individual and combined potential. These are: (i) the MRI product developed in collaboration with Medrad, Inc.; (ii) the new portable cardiac monitor introduced after the termination of the Alaris OEM (original equipment manufacturer) relationship; and (iii) discussions with at least three entities over major new OEM relationships relating to the Company’s respiratory gas monitoring system. BlueLine believes these initiatives were not executed to their full potential and did not meet expectations. BlueLine believes the current management team has failed to demonstrate that it can manage multiple new product launches, negotiate and execute new sales and partnership agreements and/or control new and expanded manufacturing processes – all of which are critical to the Company’s success. BlueLine also believes that the current Board has been lax in its oversight responsibilities and has failed to undertake any significant initiatives to redress the situation. For example, until pressured by BlueLine, the Company’s practice was not to hold Board meetings in person. As of the date of the Company’s last proxy statement, (i) no executive sessions of the Board had been held, (ii) the nominating and governance committee had never met and (iii) there has been no action taken to adjust management compensation to better link pay with performance. Finally, to our knowledge, there have not been any significant replacements or additions to management or other key positions since 2000 – notwithstanding the Company’s disappointing financial performance during this period.

Despite the Company’s current shortcomings, BlueLine is confident that it is not too late to capitalize on Criticare’s current opportunities and deliver value to the Company’s stockholders. BlueLine specializes in investing in microcap medical device companies that are having trouble realizing their inherent potential. BlueLine’s team includes individuals with extensive experience in managing, consulting to and serving as board members to such companies. Once invested, BlueLine typically plays an active role advising and assisting companies and frequently helps companies identify and recruit new officers and directors. We stand ready to play a similar role at Criticare if we are permitted the opportunity.

Accordingly, we are commencing a solicitation of written consents from the holders of the Company’s common stock to take the following actions in the following order (the “Proposals”) without a stockholders’ meeting, as permitted by Delaware law, the Company’s Restated Certificate of Incorporation and the Company’s By-laws:

Repeal each provision of the Company’s By-laws or amendment thereto adopted subsequent to March 13, 2006 and prior to the effectiveness of the Proposals;

Amend Section 3.02 of Article III of the Company’s By-laws to provide that the entire board of directors will be elected each year;

Remove all six of the present members of the Board of Directors of the Company and any person or persons elected or designated by any such directors to fill any vacancy or newly created directorship;

Amend Section 3.01 of Article III of the Company’s By-laws to fix the number of directors of the Company at five (5); and

Elect William Moore, Cindy Collier, and Robert Munzenrider and re-elect Emil Soika and Sam Humphries as directors of the Company.

As an investment firm and the Company’s largest stockholder, BlueLine’s sole interest is in seeing the Company perform to its full potential, and thereby maximize value for all of the Company’s stockholders. The new directors we propose for election to the Board will take seriously their responsibilities as directors of the Company and are committed to representing the interests of the Company’s stockholders.

WE URGE YOU TO VOTE IN FAVOR OF THESE PROPOSALS BY SIGNING, DATING AND RETURNING THE ENCLOSED CONSENT CARD.

BLUELINE PARTNERS, L.L.C.

CONSENT STATEMENT OF BLUELINE PARTNERS, L.L.C.

This Consent Statement is furnished by BlueLine Partners, L.L.C., a Delaware limited liability company, which, together with its affiliated entities (collectively, “BlueLine”), is the largest stockholder of Criticare Systems, Inc., a Delaware corporation (“Criticare” or the “Company”). This Consent Statement is being furnished in connection with the solicitation by BlueLine of written consents from the holders of Common Stock of the Company, to take the following actions in the following order (the “Proposals”) without a stockholders’ meeting, as permitted by Delaware law, the Company’s Restated Certificate of Incorporation and the Company’s By-laws:

Repeal each provision of the Company’s By-laws or amendment thereto adopted subsequent to March 13, 2006 and prior to the effectiveness of the Proposals;

Amend Section 3.02 of Article III of the Company’s By-laws to provide that the entire board of directors will be elected each year;

Remove all six of the present members of the Board of Directors of the Company and any person or persons elected or designated by any such directors to fill any vacancy or newly created directorship;

Amend Section 3.01 of Article III of the Company’s By-laws to fix the number of directors of the Company at five (5); and

Elect William Moore, Cindy Collier, and Robert Munzenrider (collectively, the “New Directors”) and re-elect Emil Soika and Sam Humphries (together with the New Directors, the “Nominees”) as directors of the Company.

All of the Proposals are designed to improve the Company’s performance and thereby maximize stockholder value for the benefit of all stockholders. Stockholders of the Company are being asked to express their consent to the Proposals on the accompanying consent card. The effectiveness of each of the Proposals is subject to, and conditioned upon, the sequential adoption of each of the prior Proposals by the holders of record, as of the close of business on the Record Date (as hereinafter defined), of a majority of the shares of Company common stock then outstanding (including the receipt of consents from such holders to the removal of each member of the Company’s Board of Directors and to the election of each new Nominee). Stockholders of record as of the close of business on the Record Date will be entitled to one vote for each share of the Company’s common stock for which they are entitled to give consent. BLUELINE RECOMMENDS THAT YOU CONSENT TO EACH OF THE PROPOSALS BY SIGNING, DATING, COMPLETING AND RETURNING THE ENCLOSED CONSENT CARD.

Section 213 of the General Corporation Law of the State of Delaware (the “DGCL”) and Section 2.05 of the Company’s By-laws provides that for the purpose of determining stockholders entitled to express consent to corporate action in writing without a meeting, the Board of Directors may fix the record date. If no record date is fixed by the Board and no prior action is required by the Board, the record date for determining stockholders entitled to express consent to corporate action in writing without a meeting shall be the day on which the first written consent is expressed. BlueLine delivered a signed consent to the Company on August 28, 2006, and no prior action by the Board was required. Accordingly, the record date for the solicitation made hereby is August 28, 2006 (the “Record Date”).

The Proposals will become effective when properly completed, unrevoked consents are signed by the holders of record on the Record Date of a majority of shares of the Company’s common stock then outstanding and such consents are delivered to the Company. The effectiveness of each of the Proposals is subject to, and conditioned upon, the adoption of each of the other Proposals by the holders of record, as of the close of business on the Record Date, of a majority of the shares of the Company’s common stock then outstanding (including the receipt of consents from such holders to the removal of each member of the Company’s Board of Directors and to the election of each Nominee). See “Consent Procedure.”

This Consent Statement and the related consent card are first being sent or made available on or about September 12, 2006 to all holders of record of shares of the Company’s common stock on the Record Date. On the Record Date, BlueLine was the beneficial owner of 1,318,700 shares of the Company’s common stock.

THIS SOLICITATION IS BEING MADE BY BLUELINE AND NOT ON BEHALF OF THE BOARD OF DIRECTORS OF THE COMPANY.

BLUELINE RECOMMENDS THAT YOU CONSENT TO EACH OF THE PROPOSALS. YOUR CONSENT IS IMPORTANT. PLEASE SIGN AND DATE THE ENCLOSED CONSENT CARD AND RETURN IT PROMPTLY TO BLUELINE PARTNERS, L.L.C. AT 4115 BLACKHAWK PLAZA CIRCLE, SUITE 100, DANVILLE, CALIFORNIA 94506, ATTENTION: SCOTT A. SHUDA.

Because the Proposals will become effective only if executed consents are returned by holders of record on the Record Date of a majority of the total number of shares of the Company’s common stock then outstanding, the failure to execute and return a consent will have the same effect as voting against the Proposals.

SUMMARY

The information in this summary is qualified in its entirety by reference to the more detailed information appearing elsewhere in this Consent Statement.

THE PROPOSALS

BlueLine is soliciting written consents from the Company’s stockholders to repeal amendments to the Company’s By-laws adopted subsequent to March 13, 2006 and prior to the effectiveness of the Proposals, amend the Company’s By-laws to provide that the entire board of directors will be elected each year, remove all six of the present directors of the Company, amend the Company’s By-laws to fix the number of directors of the Company at five (5) and elect the Nominees to serve as the directors of the Company.

VOTING SECURITIES AND PRINCIPAL HOLDERS

The Company’s common stock constitutes the only class of voting securities of the Company. Accordingly, only holders of the Company’s common stock are entitled to execute consents. For information regarding persons believed to be the beneficial owners of more than 5% of the Company’s common stock, see “Voting Securities and Principal Holders Thereof” below.

CONSENT PROCEDURE

BlueLine will pay all costs in connection with its solicitation of consents. The consents are being solicited pursuant to the procedure established by Sections 228 and 213 of the DGCL. Stockholders of record as of the close of business on the Record Date are entitled to consent to the Proposals. The Proposals will become effective when properly completed, unrevoked consents are signed by the holders of record on the Record Date of a majority of the shares of the Company’s common stock then outstanding and such consents are delivered to the Company. The effectiveness of each of the Proposals is subject to, and conditioned upon, the sequential adoption of each of the prior Proposals by the holders of record, as of the close of business on the Record Date, of a majority of the shares of the Company’s common stock then outstanding (including the receipt of consents from such holders to the removal of each member of the Company’s Board of Directors and to the election of each Nominee). To be effective, the requisite consents must be delivered to the Company by October 27, 2006. Accordingly, we ask that you deliver your signed, dated and properly completed consent to BlueLine no later than October 25, 2006.

REASONS FOR THE SOLICITATION

BlueLine beneficially owns approximately 10.7% of Criticare’s outstanding shares. We are acting as a stockholder that is concerned about its investment in the Company and asking for your consent and support in re-forming the Company’s Board to include a new majority of directors independent of management. We are committed to closely monitoring and promoting the accountability of senior management, advocating corporate governance improvements, and encouraging and overseeing efforts to maximize stockholder value. We will actively urge the new Board to, among other things: (i) hold regular, in-person meetings of the full board of directors; (ii) hold regular, in-person meetings of each board committee; (iii) hold regular executive sessions of the non-management board members; and (iv) take action to adjust management compensation to better link pay with performance. To provide for Board continuity and the perspective and skills of two directors with experience relevant to the Company’s current situation, the consent also asks you to re-elect two existing directors, Emil Soika, the Company’s Chief Executive Officer, and Sam Humphries, a current outside director and experienced executive for several medical device companies, to serve as directors.

BlueLine is concerned that the Company’s current Board of Directors has failed to properly monitor the Company’s business and to encourage actions necessary to maximize stockholder value. BlueLine has repeatedly articulated these concerns in its filings made with Securities and Exchange Commission (the “SEC”).

To assist in this regard, BlueLine has previously volunteered to join the Board and has on several occasions submitted the names of highly-qualified and independent Board candidates. The Board has never contacted any of these nominees or even acknowledged receipt of BlueLine’s recommendations.

BlueLine believes that it is time for the Company’s stockholders to have representation in the boardroom to promote greater accountability of senior management, advocate corporate governance improvements and encourage and oversee efforts to maximize stockholder value. Each of the New Directors has significant management and/or finance experience and expertise and is well suited to work with, assist and monitor the Company and its management in the execution of the Company’s business plan. We believe that, given their strong backgrounds, the New Directors will bring valuable insights to the Company that will help facilitate and enhance long term value for the Company’s stockholders. Among the areas BlueLine believes the New Directors will add value to the Board are:

o Domain expertise in healthcare

o Experience working for and running medical device companies

o Experience serving as members of board of directors of public companies

o Experience and expertise with new regulatory requirements including Sarbanes-Oxley and Regulation FD

o Financial expertise, including assisting in the creation of operating plans and budgets

o Experience in establishing performance-based compensation plans for senior management

o Experience in evaluating and executing strategic transactions

Most important, the New Directors will be independent of management and possess no loyalties other than to represent and safeguard the interests of the stockholders who have elected them. Other than William Moore, all of the Nominees are also independent of BlueLine. The New Directors are committed to working for stockholders to ensure the Company has a competent management team, all of the personnel and skills necessary to execute the Company’s business plan, better corporate governance and that all appropriate options are explored to maximize stockholder value.

THE PROPOSALS

BlueLine is seeking written stockholder consents without a meeting to the Proposals, which consist of taking the following actions in the following order:

Repeal each provision of the Company’s By-laws or amendment thereto adopted subsequent to March 13, 2006 and prior to the effectiveness of the Proposals;

Amend Section 3.02 of Article III of the Company’s By-laws to provide that the entire board of directors will be elected each year;

Remove all six of the present members of the Board of Directors of the Company and any person or persons elected or designated by any such directors to fill any vacancy or newly created directorship;

Amend Section 3.01 of Article III of the Company’s By-laws to fix the number of directors of the Company at five (5); and

Elect William Moore, Cindy Collier, and Robert Munzenrider and re-elect Emil Soika and Sam Humphries as the directors of the Company.

The effectiveness of each of the Proposals is subject to, and conditioned upon, the sequential adoption of each of the prior Proposals by the holders of record, as of the close of business on the Record Date, of a majority of the shares of the Company’s common stock then outstanding (including the receipt of consents from such holders to the removal of each member of the Company’s Board of Directors and to the election of each Nominee).

BLUELINE RECOMMENDS THAT YOU CONSENT TO EACH OF THE PROPOSALS.

PROPOSAL NO. 1 – REPEAL OF CERTAIN BYLAW PROVISIONS AND AMENDMENTS

This Proposal would repeal any measures taken by the current Board of Directors to amend the Company’s By-laws adopted after March 13, 2006 (or earlier if such amendment has not been filed with the SEC). This Proposal is designed to prevent the Company’s Board of Directors from taking actions to amend the Company’s By-laws to attempt to nullify the actions taken by the stockholders pursuant to the Proposals or to create new obstacles to the effectiveness of any of the Proposals. The Company’s By-laws filed on March 13, 2006 (the most recent publicly available version of the Company’s By-laws) state that they reflect all amendments adopted through March 13, 2006. Accordingly, this Proposal would not repeal any provision of the Company’s By-laws that has been publicly disclosed prior to the date hereof (although, as noted above, other Proposals for which consents are solicited hereby would amend Sections 3.01 and 3.02 of Article III of the Company’s By-laws). If, however, the Company’s Board of Directors has adopted since March 13, 2006, or adopts prior to the effectiveness of the Proposals, any amendment to the Company’s By-laws, this Proposal would repeal such amendment so as to prevent the Company from creating new obstacles to the effectiveness of any of the Proposals or negatively affecting our ability to obtain stockholder consents or effectuation of the will of the stockholders expressed in such consents.

PROPOSAL NO. 2 - AMENDMENT OF BY-LAWS TO PROVIDE FOR THE ANNUAL ELECTION OF DIRECTORS

This Proposal provides for the amendment of Section 3.02 of Article III of the Company’s By-laws to provide for the annual election of each member of the Board of Directors.

This amendment to the Company’s By-laws is set forth in it is entirety in Annex I to this Consent Statement. The Company’s By-laws currently provide that the Board of Directors will be divided into three classes with the term of the one class expiring each year. This By-law amendment is designed to “de-stagger” the Board and provide for the annual election of the entire Board of Directors which will encourage accountability of the Board of Directors to the stockholders.

PROPOSAL NO. 3 – REMOVAL OF DIRECTORS

Subject to approval of Proposal No. 2, this Proposal provides for the removal without cause of each member of the current Board of Directors of the Company and any other person who may be appointed as a director prior to the time the action proposed to be taken by this consent procedure becomes effective. Based on the publicly available information, the directors who would currently be removed are: Higgins D. Bailey, Jeffrey T. Barnes, Sam Humphries, N.C. Joseph Lai, Emil H. Soika and Stephen K. Tannenbaum.

PROPOSAL NO. 4 - AMENDMENT OF BY-LAWS TO SET THE SIZE OF THE BOARD AT FIVE

This Proposal provides for the amendment of Section 3.01 of Article III of the Company’s By-laws to fix the number of directors at five (5). This amendment to the Company’s By-Laws is set forth in its entirety in Annex II to this Consent Statement. The Company’s By-laws currently provide that the number of directors of the corporation shall be the number the Board of Directors establishes from time to time, but not fewer than two (2) and no more than seven (7). This By-law amendment is designed to declassify the Board and reduce the number of directors constituting the Company’s Board of Directors to five, which is how many directors would be in office if the Proposal to remove the incumbent directors is approved and the Nominees are elected.

PROPOSAL NO. 5 – ELECTION OF NOMINEES

This Proposal provides, upon the effectiveness of Proposals 2, 3 and 4, for the election as directors of the Company of the following Nominees: William Moore, Cindy Collier, Robert Munzenrider, Emil Soika and Sam Humphries, each of whom is either currently a director or has consented to serve as a new director, if elected, until the next annual meeting of stockholders and until his or her successor has been elected and qualified. One of the Nominees, William Moore, is director of BlueLine Partners, L.L.C. which may be deemed to beneficially own 1,318,700 shares of the Company’s outstanding Common Stock.

BlueLine’s principal purpose in seeking to elect the Nominees to the Company’s Board of Directors is to install a Board of Directors that is independent of management and is willing, consistent with their fiduciary duties to the Company’s stockholders, to take a more active role in directing and overseeing management while maintaining continuity and perspective relevant to the Company’s current situation through the re-election of two current directors, Emil Soika and Sam Humphries.

Each director has an obligation under the DGCL to discharge his or her duties as a director on an informed basis, in good faith, with due care and in a manner the director honestly believes to be in the best interests of the Company. The Nominees intend to discharge these obligations fully.

Although BlueLine has no reason to believe that any of the Nominees will be unable or unwilling to serve as directors, if any of the Nominees is not available for election, the Board of Directors, including any Nominee or Nominees who are elected pursuant to this proposed action by written consent will vote for the election of such other nominee or nominees as may be proposed by BlueLine.

BlueLine does not make any representation as to the accuracy or completeness of the information contained in the Company’s proxy statement.

SOLICITATION OF CONSENTS

Solicitation of consents may be made by the officers and directors of BlueLine. Consents will be solicited by mail, advertisement, telephone or telecopier or in person. No such persons will receive additional compensation for such solicitation.

Banks, brokers, custodians, nominees and fiduciaries will be requested to forward solicitation materials to beneficial owners of the shares of the Company’s common stock. BlueLine will reimburse banks, brokers, custodians, nominees and fiduciaries for their reasonable expenses for sending solicitation material to the beneficial owners.

The cost of solicitation of consents to the Proposals will be borne by BlueLine. BlueLine will not seek reimbursement of the costs of this solicitation from the Company. Costs related to the solicitation of consents to the Proposals include expenditures for attorneys, consent solicitors, public relations advisors, printing, advertising, postage, litigation and related expenses and filing fees are expected to be approximately $35,000 in the aggregate.

BLUE LINE IS NOT REQUESTING OR AUTHORIZING ANY STOCKHOLDER OF THE COMPANY OR ANY RECIPIENT OF THIS CONSENT STATEMENT TO ASSIST WITH THE SOLICITATION OF STOCKHOLDER CONSENTS OR TO CONTACT STOCKHOLDERS OF THE COMPANY ON ITS BEHALF.

If BlueLine acted in concert with other stockholders of the Company in conducting this consent solicitation, then it might be necessary for certain additional disclosures or filings to be made with the SEC, which could complicate BlueLine’s efforts. Accordingly, BlueLine is asking that you not solicit other stockholders or otherwise attempt to persuade them to return an executed consent.

CONSENT PROCEDURE

Section 228 of the DGCL states that, unless the certificate of incorporation of a Delaware corporation otherwise provides, any action required to be taken at any annual or special meeting of stockholders of that corporation, or any action that may be taken at any annual or special meeting of those stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, is signed by the holders of outstanding stock having no less than the minimum number of votes that would be necessary to authorize or take that action at a meeting at which all shares entitled to vote thereon were present and voted, and those consents are delivered to the corporation by delivery to its registered office in Delaware, its principal place of business or an officer or agent of the corporation having custody of the books in which proceedings of meetings of stockholders are recorded. The Company’s Restated Certificate of Incorporation does not prohibit stockholder action by written consent.

Section 213(b) of the DGCL provides that the record date for determining the stockholders of a Delaware corporation entitled to consent to corporate action in writing without a meeting, when no prior action by the corporation’s Board of Directors is required and the Board has not fixed the record date, will be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the corporation by delivery to its registered office in Delaware, its principal place of business or an officer or agent of the corporation having custody of the books in which proceedings of meetings of the stockholders are recorded. The Company’s Board has not fixed a record date with respect to the Proposals and no prior action is required by the Company’s Board of Directors with respect to the Proposals.

BlueLine delivered the first consent on August 28, 2006 which means that the Record Date is August 28, 2006.

If the Proposals are adopted, prompt notice will be given pursuant to Section 228(e) of the DGCL to stockholders who have not executed consents.

EFFECTIVENESS AND REVOCATION OF CONSENTS

The corporate actions proposed herein will be adopted when properly completed, unrevoked consents are signed and dated by the holders of record on the Record Date of a majority of the shares of the Company’s common stock then outstanding and such consents are delivered to the Company, provided that under Section 228(c) of the DGCL the requisite consents must be delivered to the Company within 60 days of the earliest dated consent delivered to the Company, or October 27, 2006. However, we ask that stockholders submit signed, dated and properly completed consents to BlueLine Partners, L.L.C. no later than October 25, 2006. The effectiveness of each of the Proposals is subject to, and conditioned upon, the sequential adoption of each of the prior Proposals by the holders of record, as of the close of business on the Record Date, of a majority of the shares of the Company’s common stock then outstanding (including the receipt of consents from such holders to the removal of each member of the Company’s Board of Directors and to the election of each Nominee).

BlueLine plans to present the results of a successful solicitation with respect to the corporate actions proposed herein to the Company as soon as possible.

An executed consent may be revoked at any time before expiration by marking, dating, signing and delivering a written revocation before the time that the action authorized by the executed consent becomes effective. A revocation may be in any written form validly signed and dated by the record holder as long as it clearly states that the consent previously given is no longer effective. The delivery of a subsequently dated consent card which is properly completed will constitute a revocation of any earlier consent. The revocation may be delivered to BlueLine Partners, L.L.C. at 4115 Blackhawk Plaza Circle, Suite 100, Danville, California 94506, facsimile: (925) 648-2086, Attention: Scott A. Shuda or any other address provided by the Company. Although a revocation is effective if delivered to the Company, BlueLine requests that either the original or photostatic copies of all revocations of consents be mailed, faxed or otherwise delivered to BlueLine at the address set forth above, so that BlueLine will be aware of all revocations and can more accurately determine if and when signed, dated and properly completed consents to the actions described herein have been received from the holders of record on the Record Date of a majority of outstanding shares of the Company’s common stock.

SPECIAL INSTRUCTIONS

If you were a record holder of shares of the Company’s common stock as of the close of business on the Record Date, you may elect to consent to, withhold consent to or abstain with respect to each Proposal by marking the “CONSENTS,” “DOES NOT CONSENT,” or “ABSTAIN” box, as applicable, underneath each such Proposal on the accompanying consent card and signing, dating and returning it promptly to BlueLine Partners, L.L.C. at 4115 Blackhawk Plaza Circle, Suite 100, Danville, California 94506, Attention: Scott A. Shuda.

In addition, you may withhold consent to the removal of any individual member of the Company’s Board of Directors or to the election of any individual Nominee by writing such person’s name on the consent card in the section for withholding consent. However, the effectiveness of each of the Proposals is subject to, and conditioned upon, the receipt of consents from the holders of record on the Record Date of a majority of the shares of the Company’s common stock then outstanding to the removal of each member of the Company’s Board of Directors and to the election of each Nominee.

If a stockholder returns a properly signed and dated consent but has failed to check a box marked “CONSENTS,” “DOES NOT CONSENT” or “ABSTAIN” for one or more of the Proposals, such stockholder will be deemed to have consented to each Proposal, except that such stockholder will not be deemed to have consented to the removal of any member of the Company’s Board of Directors or the election of any Nominee whose name the stockholder writes-in in the section for withholding consent on the consent card.
