2013 ANNUAL MEETING OF STOCKHOLDERS

OF

SIGNATURE GROUP HOLDINGS, INC.

PROXY STATEMENT

OF

THE CONCERNED STOCKHOLDERS OF SIGNATURE GROUP HOLDINGS

PLEASE COMPLETE, SIGN, DATE AND MAIL THE ENCLOSED GOLD PROXY CARD TODAY

To the Stockholders of Signature Group Holdings, Inc.:

We, the Concerned Stockholders of Signature Group Holdings (the “Concerned Signature Stockholders,” “we” or “us”), the participants in this solicitation (this “Solicitation”), are furnishing this Proxy Statement (this “Proxy Statement”) and the enclosed GOLD proxy card (the “Proxy Card” or “Proxy”) to you as a stockholder of Signature Group Holdings, Inc., a Nevada corporation (the “Company”).

We are deeply frustrated and dissatisfied with the performance, leadership and direction of the Company. The Company’s Board of Directors (the “Board”) has failed to consummate any major acquisitions in the past year, has failed to generate stockholder value at a time when the equity markets in the United States significantly increased, and has failed to put the Company on track to achieve these twin critical goals. Thus we believe it is necessary to have the Company led by a new, highly competent and skilled board of directors that consists of our nominees.

Our slate of nominees, unlike the one proposed by the Company, includes executives and investors who have documented track records of success acquiring and building companies that maximize stockholder value. Our slate includes people who have led significant enterprises, effected major and material transactions, improved businesses significantly, and generated returns for stockholders.

We ask you to support our director nominees and vote as we recommend for the other proposals before the Company’s 2013 Annual Meeting of Stockholders to be held at the Sheraton Gateway Los Angeles Hotel, 6101 W. Century Boulevard, Los Angeles, California 90045, on July 16, 2013, beginning at 2:00 p.m. Pacific Time (including any adjournment or postponement thereof and any meeting which may be called in lieu thereof, the “2013 Annual Meeting”).

The Proxies are being solicited by and on behalf of the Concerned Stockholders of Signature Group Holdings, who are comprised of: (i) New Signature, LLC (“New Signature”); (ii) Charlestown Capital Partners, LLC (“Charlestown Capital”) and Raj Maheshwari (Mr. Maheshwari and Charlestown Capital collectively, hereinafter called “Charlestown”); (iii) Bouchard 10S LLC and Craig T. Bouchard (Mr. Bouchard and Bouchard 10S LLC collectively, hereinafter called “Bouchard”); (iv) Steven Gidumal; (v) Duart Holdings LLC and Malcolm F. MacLean IV (Mr. MacLean and Duart Holdings LLC, collectively, hereinafter called “MacLean”); (vi) Clifford D. Nastas and (vii) Lee Smith.

Specifically, we seek your support for the following purposes:

The Company has set the record date for determining stockholders entitled to notice of and to vote at the Annual Meeting as May 29, 2013 (the “Record Date”). The mailing address of the principal executive offices of the Company is 15303 Ventura Boulevard, Suite 1600, Sherman Oaks, California 91403. Stockholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting. According to the Company’s Preliminary Proxy Statement as filed with the Securities and Exchange Commission on April 19, 2013, as of April 15, 2013 (the “Company Statement”), the Company had 121,426,840 shares of common stock, par value $0.01 per share, outstanding and expected to be entitled to vote at the Annual Meeting.

As of the date hereof, the Concerned Signature Stockholders own an aggregate of 4,114,314 shares, or approximately 3.39%, of the Company’s issued and outstanding Common Stock. We intend to vote such shares FOR the election of the Concerned Stockholder Nominees, AGAINST the Articles of Amendment, FOR the ratification of the selection of Squar Milner as independent auditors, AGAINST the approval of the Executive Compensation, for a ONE YEAR period between advisory votes on Executive Compensation and AGAINST the Adjournment Proposal, as described herein.

The Concerned Signature Stockholders believe that Concerned Stockholder Nominees, if elected, will provide the Company with a new Board of highly qualified individuals whose experience includes serving on the boards of directors of public companies or as executive officers of companies engaged in merger and acquisition activity, and who are motivated to lead the Company forward for the benefit of the Company’s stockholders. The Concerned Stockholder Nominees are Craig T. Bouchard, Steven Gidumal, Malcolm F. MacLean IV, Raj Maheshwari, and Clifford D. Nastas, a set of nominees including two chief executive officers, several experienced investors, and one former director of the Company. Therefore, the Concerned Signature Stockholders are soliciting your Proxy on the enclosed GOLD Proxy Card for the 2013 Annual Meeting and ask that you deliver your completed, signed, and dated GOLD Proxy Card as promptly as possible by mail in the enclosed postage-paid envelope.

IMPORTANT

THIS SOLICITATION IS BEING MADE BY THE CONCERNED STOCKHOLDERS OF SIGNATURE GROUP HOLDINGS, INC. AND NOT ON BEHALF OF THE BOARD OF DIRECTORS OR MANAGEMENT OF THE COMPANY. THE CONCERNED SIGNATURE STOCKHOLDERS ARE NOT AWARE OF ANY OTHER MATTERS TO BE BROUGHT BEFORE THE 2013 ANNUAL MEETING OTHER THAN AS DESCRIBED HEREIN. SHOULD OTHER MATTERS, WHICH THE CONCERNED SIGNATURE STOCKHOLDERS ARE NOT AWARE OF A REASONABLE TIME BEFORE THIS SOLICITATION, BE BROUGHT BEFORE THE 2013 ANNUAL MEETING, THE PERSONS NAMED AS PROXY ON THE ENCLOSED GOLD PROXY CARD WILL VOTE ON SUCH MATTERS IN THEIR DISCRETION.

YOUR VOTE IS IMPORTANT, NO MATTER HOW MANY SHARES OF THE COMPANY’S COMMON STOCK YOU OWN (YOUR “SHARES”). THE CONCERNED SIGNATURE STOCKHOLDERS URGE YOU TO SIGN, DATE AND RETURN THE GOLD PROXY CARD IN FAVOR OF THE ELECTION OF THE CONCERNED STOCKHOLDER NOMINEES.

WE URGE YOU NOT TO SIGN ANY PROXY CARD THAT MAY BE SENT TO YOU BY THE COMPANY (THE WHITE CARD).

REASONS FOR OUR SOLICITATION

We, the Concerned Stockholders of Signature Group Holdings, Inc., are deeply frustrated and dissatisfied with the performance, leadership and direction of the Company. Another year has passed under the control and leadership of this Board without tangible results. By failing to develop and execute plans to effectively use its considerable assets and by continuing to waste time and cash, we believe the Company has squandered opportunities for growth and severely limited its performance potential. It is time for fresh leadership and perspectives. It is time for the current members of the Board to step aside for our slate of nominees, who will institute and execute a business plan (and engage a competent and new chief executive officer) and drive results.

The Concerned Signature Stockholders believe that the current management team and Board lack the skill set, the experience and the ability to maximize stockholder value of the Company. We aim to put the Company on firm footing by electing a Board of experienced investors and leaders who are capable of identifying, analyzing, and consummating acquisitions. We believe we provide a significant upgrade in experience and qualifications at the Board level, with long-standing relationships with professionals in the equity and debt markets, and will be able to attract an executive leader for the business going forward.

Lack of Leadership by the Board, Destruction of Stockholder Value, Mr. Noell’s Termination Package

We are glad, as stockholders, that Chief Executive Officer, Craig Noell, resigned. We note that in March 2013, one of the Concerned Signature Stockholders publicly filed a letter that had been sent previously to the Company, expressing frustration with the Company’s management. Two weeks later, Mr. Noell resigned. If the Board were already aware of Mr. Noell’s poor performance, then it should not have taken a letter from a stockholder to spur the Board into taking this long-needed action.

However, Mr. Noell’s resignation reflects poorly on the current Board, and the Board has continued to act counter to stockholder interests in its handling of Mr. Noell’s departure. Mr. Noell received a termination package from the Board that includes 24 months of severance at a cost of $650,000 – even though his employment contract had only eight more months to run. In other words, the Board needlessly granted Mr. Noell 16 additional months of unnecessary and unwarranted compensation. Furthermore, the current Board permitted Mr. Noell to keep over 3,000,000 options and restricted stock awards which his tenure at the Company did nothing to warrant. And despite structuring this lavish departure gift to Mr. Noell, he was also allowed to remain on the Board.

Mr. Noell’s record at the Company, and this Board’s record in managing him and guiding the Company, is dismal.

3

Under Mr. Noell’s and the majority of this Board’s stewardship from June 2010 through December 31, 2012, stockholders have suffered the following:

During Mr. Noell and this Board’s tenure, the S&P 500 Index has risen over 50%, while the shares of the Company have declined 25%. Yet this Board rewarded Mr. Noell lavishly throughout his tenure and continued that pattern as Mr. Noell left the Company as CEO.

In this context, the economic gifts awarded by the Board to Mr. Noell upon his departure as CEO raise significant questions about the Board’s judgment, competence, negotiating skills and process. The Chairman, Mr. Colville, did not lead the Company to an arms-length separation agreement with Mr. Noell, perhaps because Mr. Colville used to work for Mr. Noell. The lack of a succession plan for a new permanent chief executive officer for the Company, since Mr. Colville is presently acting as an interim CEO, speaks volumes (and poorly) of the Board’s leadership, strategic and management planning, and good corporate governance practices. The Board should have insisted on Mr. Noell’s immediate resignation from the Board as part of any termination package (as is customary in our experience), and should not have approved the material, economic package for Mr. Noell.

Lack of a Meaningful Transaction; Failure to Maximize the Company’s Most Valuable Asset

A key Company asset is the value of its net operating losses, as the Company itself recognizes. As of December 31, 2012, the Company reports federal net operating losses of almost $887 million and California NOLs of approximately $980 million, and has placed a valuation allowance of approximately $375 million for this asset. Yet the market value of the Company is only, as of April 22, 2013, approximately $60 million. The Company has been charged with consummating significant and material acquisitions to generate enterprise and stockholder value, but in almost three years since its emergence from bankruptcy, this Board and management team has executed only two acquisitions in totally unrelated industries, neither of them meaningful to the Company’s results, despite being staffed for acquisitions and paying generous compensation to its deal-makers.

During this same three-year period, interest rates have been at unprecedented lows, providing a wealth of financing options for a company that knows how to identify and execute transactions. The Company’s management has consistently blamed the lack of a deal on various administrative concerns that supposedly occupied the time of management. However, true dealmakers will find meaningful transactions that will enhance stockholder value whatever the administrative issues. In our view, the current situation demonstrates a lack of competence, management inexperience, Board inexperience and inability to focus on the correct priorities.

This must change. Under the leadership of our nominees, we believe it will change. We have access to material deal flow, we have the skills and desire to oversee a robust M&A program, and we have track records of building companies organically and through material acquisitions. The current Board does not. It can make excuses, but it had its chance and failed to deliver results.

Excessive Compensation to Senior Management

We, and our fellow stockholders, should be concerned about the level of compensation paid to the senior management team based on the lack of tangible results and stockholder return. Upon emergence from bankruptcy, the annual salaries of senior management were limited to $150,000 each. In August 2011, the Company entered into employment agreements with members of management. With these contracts, compensation exploded to the upside:

4

Shareholders Deserve a Competent and Highly Qualified Board Free from Questionable Related Party Transactions

We believe several of the current Board members, who are proposed by the Company for re-election to the Board, lack the qualifications to sit on the Board while it is in its current deal acquisition phase. And yet despite this, the current Board and management have no qualms about executing related party transactions that may not be in the best interests of the Company’s stockholders.

For all of these reasons, we urge other concerned stockholders to join us in finally putting in place a competent Board and management team. We will put in place an effective Chief Executive Officer immediately upon election, drawing from our professional network. Further, our slate of Concerned Stockholder Nominees will be focused on maximizing stockholder value and if our Concerned Stockholder Nominees do not lead to an increase in stockholder value, we will voluntarily make changes to our management and Board members. We believe strongly in the value inherent in the Company and our focused goal is to maximize this value as quickly and efficiently as possible.

BACKGROUND OF OUR SOLICITATION

The Concerned Signature Stockholders include a former director of the Company and several individuals and entities who are stockholders of the Company. As stockholders, members of the Concerned Signature Stockholders have had, in the past, regular conversations and meetings with members of the management team (including the former CEO, Mr. Noell, and his reports). One of our proposed nominees, as a former director, had regular interactions with the Board and management. These contacts were for general business purposes. Over time, certain members of the Concerned Signature Stockholders grew increasingly frustrated with the Company’s failure to develop and execute a business plan that would drive tangible economic results and stockholder value.

From 2011 to 2013, Raj Maheshwari and Craig T. Bouchard approached the Company to suggest and discuss potential acquisition targets for the Company; none of these reached the negotiation stage.

In April 2011, Steven Gidumal joined the Board of the Company and served until July 24, 2012, the date of the Company’s 2012 Annual Meeting of Stockholders. In April 2012, the Company selected its slate of director nominees for election at the Company’s 2012 Annual Meeting of Stockholders. Mr. Gidumal was not included as a nominee on the Company’s slate. Mr. Gidumal believes he was not re-nominated to the slate of Directors over his efforts to reign in compensation. On May 8, 2012, he submitted to the Board a nomination for himself as an additional director nominee at the 2012 Annual Meeting. The Company reported that it considered his nomination and declined to include him in its recommended slate for the meeting.

In January 2013, Mr. Maheshwari sent an e-mail to Philip Tinkler, a Board member and Chief Operating and Financial Officer of Equity Group Investments (“EGI”), and Evan Harwood, of EGI, expressing his concerns about the Company’s and Board’s expense management, including an excess in executive compensation, cash burn rate, and a lack of initiatives, including the failure of the Company to identify additional acquisitions and to maximize Company stockholder value.

On March 11, 2013, Mr. Maheshwari sent a private letter to the independent members of the Board expressing the same concerns described in the e-mail sent to Mr. Tinkler.

On March 13, 2013, W. Christopher Manderson, the Company’s General Counsel, offered to disclose non-public information about the Company to Mr. Maheshwari and Charlestown Capital, subject to a Non-Disclosure Agreement. The Company and Charlestown Capital signed the Non-Disclosure Agreement on March 18, 2013.

On March 20, 2013, Mr. Manderson offered to organize a conference call involving Mr. Noell, Mr. Maheshwari, and the other members of the Charlestown Capital team. A teleconference among Messrs. Maheshwari, John Weber and Smith, of Charlestown Capital, and Messrs. Noell and Manderson, of the Company, was held on March 26, 2013, where the Company’s issues were further discussed.

On March 28, 2013, Charlestown Capital released, via PR Newsletter, the letter that it had sent to the independent members of the Board on March 11, 2013.

On April 2, 2013, Mr. Noell e-mailed Mr. Maheshwari an offer to provide additional updates on the issues at the Company and give Mr. Maheshwari the opportunity to speak to Mr. Tinkler and G. Christopher Colville, directors of the Company.

On April 11, 2013, Mr. Noell’s resignation as CEO of the Company was made public.

On April 15, 2013, Messrs. Maheshwari, Bouchard, Gidumal, Nastas and MacLean created New Signature, LLC, in order to propose a set of corporate changes and new directors for the Board.

On April 15, 2013, Mr. Maheshwari spoke with Mr. Tinkler about some events at the Company, including the appointment of Mr. Colville as the new Chief Executive Officer of the Company.

On April 22, 2013, Mr. Maheshwari, on behalf of Charlestown Capital, terminated the Non-Disclosure Agreement.

On April 24, 2013, Mr. Maheshwari, on behalf of Charlestown Jupiter Fund, LLC (a wholly owned fund of Charlestown Capital and record owner of shares of the Company’s stock), as required by the Company’s Bylaws, submitted the nominations for the Concerned Stockholder Nominees to the Company’s Corporate Secretary, Mr. Manderson. On April 26, 2013, the Company acknowledged receipt of these nominations and requested the completion of standard Director & Officer Questionnaires for review by the Board’s Nominating & Governance Committee by May 3, 2013. The Concerned Stockholder Nominees are in the process of completing such questionnaire.

The business address for each of the Concerned Stockholder Nominees, is c/o New Signature, LLC, 1325 Avenue of the Americas, 28^th Floor, New York, New York 10019.

We believe that each of the Concerned Stockholder Nominees qualifies as independent within the meaning of “independence” set forth in the rules of the NYSE MKT Company Guide, and we have no knowledge of any facts that would prevent a determination

8

that each of the Concerned Stockholder Nominees is independent. Because the Company’s common stock is quoted only on the OTCQX Bulletin Board and is not listed on a national securities exchange and therefore, no specific independence requirements apply to the Company’s directors. We, therefore, have selected the NYSE MKT stock exchange, and have analyzed the independence of our nominees under the rules of the NYSE MKT Company Guide.

None of the Concerned Stockholder Nominees has carried on an occupation or employment, during the past five years, with the Company or any corporation or organization which is or was a parent, subsidiary or other affiliate of the Company, and, with the exception of Mr. Gidumal, none of the Concerned Stockholder Nominees has ever served on the Company’s Board. No family relationships exist between any Concerned Stockholder Nominee and any director or executive officer of the Company. Charlestown Capital, with which Mr. Maheshwari is affiliated, Steven Gidumal, Bouchard 10S LLC, with which Mr. Bouchard is affiliated, Duart Holdings LLC, with which Mr. MacLean is affiliated, and Mr. Nastas are equity holding members of New Signature, LLC, the entity filing this Proxy Statement.

Each of the Concerned Stockholder Nominees, or their respective associates, owns beneficially, directly or indirectly, or of record but not beneficially, securities of the Company or any parent or subsidiary of the Company, the acquisitions or dispositions of which made in the last two years are shown on Annex B to this Proxy Statement.

There are no material proceedings to which any Concerned Stockholder Nominee or any of his associates is a party adverse to the Company or any of its subsidiaries, nor does any Concerned Stockholder Nominee have a material interest adverse to the Company or any of its subsidiaries.

None of the Concerned Stockholder Nominees has been involved in any legal proceedings in the preceding ten years which are described in Item 401(f) of Regulation S-K promulgated under the Securities Act of 1933 (“Regulation S-K”) and which must be disclosed as material for purposes of an evaluation of the integrity or ability of any person nominated to become a director under the federal securities laws.

Except for Mr. Gidumal, neither the Concerned Stockholder Nominees nor any of their associates has received any cash compensation, cash bonuses, deferred compensation, compensation pursuant to plans, or other compensation, from, or in respect of, services rendered on behalf of the Company, or is subject to any arrangement described in Item 402 of Regulation S-K. Mr. Gidumal served on the Board in 2011 and 2012. In 2011, Mr. Gidumal received $33,995 in cash and stock awards worth $52,192 in compensation for his service as a director of the Company. In 2012, Mr. Gidumal received $26,130 in cash and stock awards worth $75,000 in compensation for his service as a director of the Company.

The Concerned Stockholder Nominees have not received any compensation from the Concerned Signature Stockholders for serving as nominees, and they will not receive any compensation from us for their services as directors of the Company if elected. Each of the Concerned Stockholder Nominees, if elected, will be entitled to receive from the Company compensation paid by the Company to its non-employee directors. The compensation currently paid by the Company to its non-employee directors is described in the Company Statement. Other than as stated in this Proxy Statement, there are no arrangements or understandings between members of the Concerned Signature Stockholders and any of the Concerned Stockholder Nominees or any other person or persons pursuant to which the nomination of the Concerned Stockholder Nominees described herein is to be made. Each of the Concerned Stockholder Nominees has consented to be named in this Proxy Statement and to serve as a director of the Company if elected as such at the 2013 Annual Meeting.

The Concerned Signature Stockholders do not expect that any of the Concerned Stockholder Nominees will be unable to stand for election, but in the event that such persons are unable to serve or for good cause will not serve, the Shares represented by the enclosed GOLD Proxy Card will be voted for substitute nominees, to the extent this is not prohibited under the Amended and Restated Bylaws of the Company (the “Bylaws”) and applicable law. In addition, the Concerned Signature Stockholders reserve the right to nominate substitute persons if the Company makes or announces any changes to its Bylaws or takes or announces any other action that has, or if consummated would have, the effect of disqualifying any or all of the Concerned Stockholder Nominees, to the extent this is not prohibited under the Bylaws and applicable law. In any such case, Shares represented by the enclosed GOLD Proxy Card will be voted for such substitute nominees. The Concerned Signature Stockholders reserve the right to nominate additional persons, to the extent this is not prohibited under the Bylaws and applicable law, if the Company increases the size of the Board above its existing size. Additional nominations made pursuant to the preceding sentence are without prejudice to the position of the Concerned Signature Stockholders that any attempt to increase the size of the current Board constitutes an unlawful manipulation of the Company’s corporate machinery.

YOU ARE URGED TO VOTE FOR THE ELECTION OF THE CONCERNED STOCKHOLDER NOMINEES ON THE ENCLOSED GOLD PROXY CARD.

PROPOSAL NO. 2

COMPANY PROPOSAL TO APPROVE AN AMENDMENT

TO THE AMENDED AND RESTATED ARTICLES OF INCORPORATION TO INCREASE

THE AUTHORIZED COMMON STOCK OF THE COMPANY

As discussed in further detail in the Company Statement made in connection with the 2013 Annual Meeting, the Board has proposed an amendment to Article 4, Section 4.1 of the Company’s Amended and Restated Articles of Incorporation (the “Articles”) to increase the number of shares of common stock the Company is authorized to issue from 190,000,000 to 665,000,000 shares. For the reasons set forth below, the Concerned Signature Stockholders oppose the proposed increase in authorized shares of Common Stock and urges fellow stockholders to vote AGAINST this Proposal No. 2.

We are opposed to the Company’s proposal to amend the Articles to increase the authorized number of shares of common stock of the Company and recommend a vote AGAINST this proposal. The Board, as chaired by Mr. Colville and with Mr. Colville as interim Chief Executive Officer, has failed to consummate material acquisitions and make use of the significant federal and California NOLs. We believe it would be a gross mistake to provide the current Board and management team with further authority over our checkbook (here equity instead of cash) given their business failures to date. If the Concerned Stockholder Nominees are elected to the Board, we will promptly develop and execute a robust, actionable merger and acquisition program. Only after that has occurred can a proposal to increase the number of shares be evaluated properly.

In the Company Statement, the Company states that it needs an additional 475,000,000 authorized shares for raising capital or for offering as full or partial consideration for acquisition opportunities. Further, the Company states that it specifically plans to use the increased common shares to conduct a “Rights Offering” pursuant to which existing Company stockholders would be granted “Rights” on a pro rata basis to acquire newly issued shares of the Company’s common stock. In addition, the Company notes that once a company successfully uses one Rights Offering, it frequently engages in additional future Rights Offerings.

The Company states that such a Rights Offering would significantly reduce the amount of potential dilution to the Company’s existing stockholders as compared to the dilution than can occur in a traditional issuance and sale of equity securities. What the Company fails to mention is that this dilution protection only applies to the extent that an existing stockholder actually participates in full in the Rights Offering (i.e., invests more money in the Company’s common stock by purchasing their Rights) and that the Rights Offering is structured so that other existing stockholders are not allowed to exercise Rights transferred to them from non-participating stockholders. As the Company notes, if stockholders approve the increase in the number of authorized shares of common stock, the Company would not need to seek any further stockholder approval nor provide any prior notice to stockholders in order to conduct a Rights Offering. This would give the current Board significant discretion, a privilege which we believe that this Board has not earned.

We believe a Rights Offering forces existing Company stockholders who are currently awaiting a return on their investment to invest even more money into an underperforming company, which just had a resignation of its CEO, has an interim CEO located far from corporate headquarters and has been burning cash, in order to avoid dilution or to realize the Company’s existing potential. While the Concerned Signature Stockholders want to pursue acquisitions and growth for the Company, we believe that the Company should identify strong acquisition opportunities, utilize its cash position (the Company reported approximately $54 million in cash and cash equivalents as of December 31, 2012 in its Form 10-K for the year ended December 31, 2012 filed with the SEC on April 1, 2013) and its major asset – its significant net operating loss carry forwards- and take advantage of borrowing rates at near-historic lows to fuel this growth. If the Company is unable to execute an acquisition strategy in any other way or to access the currently favorable credit markets for good acquisitions, it needs to be very clear with stockholders about these failures. Given the current Board’s and management’s history in failing to make significant acquisitions with the Company’s existing assets, we see no reason to punish existing stockholders for dilution when accretive transactions can be structured with existing Company assets.

The Company’s proposed amendment to Article 4, Section 4.1 of the Amended and Restated Articles of Incorporation is shown below. If stockholders compare the Company’s deletions indicated by strike-outs and additions indicated by underlining, they can see that this Board wants to increase the Company’s authorized common stock from 190 million to 665 million. This is a staggering increase in authorized common stock, which we strongly oppose.

“Section 4.1 Shares, Classes and Series Authorized

This Corporation is authorized to issue two classes of stock to be designated, respectively, “Common Stock” and “Preferred Stock”. The total number of shares of all classes of capital stock which the Corporation shall have authority to issue is TwoSix Hundred Seventy-Five Million (200,000,000675,000,000) shares, of which OneSix Hundred NinetySixty-Five Million (190,000,000665,000,000) shares shall be designated as Common Stock with a par value of $0.01 per share, and Ten Million (10,000,000) shares shall be designated as Preferred Stock with a par value of $0.01 per share. The Common Stock and Preferred Stock may be collectively referred to herein as the “Capital Stock.” The Corporation shall be prohibited from issuing non-voting securities, whether Common Stock or Preferred Stock.”

10

THE CONCERNED SIGNATURE STOCKHOLDERS OPPOSE PROPOSAL 2 AND RECOMMEND THAT STOCKHOLDERS VOTE “AGAINST” APPROVAL OF THE PROPOSED AMENDMENT TO INCREASE THE TOTAL NUMBER OF AUTHORIZED SHARES.

PROPOSAL NO. 3

COMPANY PROPOSAL TO RATIFY APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC

ACCOUNTING FIRM

As discussed in further detail in the Company Statement, the Board has selected Squar Milner, Peterson, Miranda & Williamson, LLP to serve as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2013.

THE CONCERNED SIGNATURE STOCKHOLDERS DO NOT OBJECT TO THE RATIFICATION OF THE APPOINTMENT OF SQUAR MILNER AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2013 AND INTEND TO VOTE THEIR SHARES “FOR” THIS PROPOSAL.

PROPOSAL NO. 4

ADVISORY APPROVAL OF EXECUTIVE COMPENSATION

The Dodd-Frank Wall Street Reform and Consumer Protection Act gave stockholders the opportunity to show their disapproval of corporate pay practices for executive officers, on an advisory basis, by adding Section 14A to the Exchange Act. As we set forth in the Reasons for This Solicitation section above, the Concerned Signature Stockholders believe that this Board and the Company have followed poor executive pay practices in light of the Company’s performance.

The Company asked that the stockholders approve the following resolution at the 2013 Annual Meeting:

“RESOLVED, that the Company’s stockholders approve, on an advisory basis, the compensation paid to the named executive officers, as disclosed in the Company Statement for the 2013 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the compensation tables and accompanying narrative disclosure.”

While the vote on this proposal is advisory and therefore not binding on the Company, the Board, or the Governance, Nominating and Compensation Committee of the Board, we feel that a vote AGAINST this resolution will send an appropriate message to the Company and to the market generally that the Company’s stockholders do not believe that the Company’s executive compensation practices and amounts currently reflect appropriate compensation for the Company’s past and current performance, nor do they appropriately align the interests of the Company’s executive officers with its stockholders. The Company’s Board needs to revisit its executive compensation philosophy, and therefore, we do not support approving the Company’s advisory vote on the Executive Compensation. Further, in light of the significant waste of stockholder assets by gifting to former CEO Mr. Noell an excessive severance package, we believe stockholders should vote against Proposal No. 4.

THE CONCERNED SIGNATURE STOCKHOLDERS OPPOSE PROPOSAL 4 AND RECOMMEND THAT STOCKHOLDERS VOTE “AGAINST” THE COMPANY PROPOSAL FOR STOCKHOLDER APPROVAL OF EXECUTIVE COMPENSATION.

PROPOSAL NO. 5

ADVISORY VOTE ON FREQUENCY OF FUTURE ADVISORY APPROVALS

OF EXECUTIVE COMPENSATION

The Dodd-Frank Wall Street Reform and Consumer Protection Act also requires the Company to provide stockholders with the opportunity to indicate at least once every six years, on an advisory basis, their preference as to the frequency of future advisory votes (once every one, two or three years) on the compensation of our named executive officers. The Company has recommended that stockholders vote on future “say-on-pay” votes every year.

Given the poor past executive pay practices of the Company, the level of growth and strategic activity that the Company should be engaging in, and the level of responsiveness to the Company’s stockholders that the Concerned Stockholder Nominees desire to exhibit when elected to the Board of Directors, the Concerned Signature Stockholders also recommend an annual advisory vote on executive compensation. We believe it is important for the Company to receive frequent feedback from its stockholders in a range of areas, including in executive compensation, especially in light of the growth the Concerned Stockholder Nominees believe they can bring to the Company.

11

We believe that a vote of ONE YEAR on this Proposal will help demonstrate that the Company’s stockholders are active and engaged in the process of turning around the Company. If our recommendation is adopted by the stockholders, the next “say-on-pay” vote would be held at the 2014 annual meeting of stockholders.

THE CONCERNED SIGNATURE STOCKHOLDERS RECOMMEND THAT STOCKHOLDERS VOTE FOR “ONE YEAR” AS THE PREFERRED FREQUENCY FOR ADVISORY APPROVALS OF EXECUTIVE COMPENSATION.

PROPOSAL NO. 6

THE COMPANY’S PROPOSAL REGARDING ADJOURNMENT OF THE 2013 ANNUAL MEETING

As discussed in further detail in the Company Statement, the Company has indicated that the Board may propose to adjourn the 2013 Annual Meeting to a later date or dates in order to permit the solicitation of additional proxies if there are not sufficient votes at the time of the 2013 Annual Meeting to approve Proposal 2 – an amendment to the Company’s Amended and Restated Articles of Incorporation to increase the number of the Company’s authorized shares. As the Company reports in the Company Statement, if stockholders approve this proposal, the Company could adjourn the 2013 Annual Meeting, and any adjourned session of the 2013 Annual Meeting, to use the additional time to solicit additional proxies in favor of Proposal 2, including the solicitation of proxies from stockholders who have previously voted against those proposals.

Approval of this proposal could mean that, even if proxies representing a sufficient number of votes against Proposals 2 have been received, the Company could adjourn the 2013 Annual Meeting without a vote on Proposal 2 and seek to convince the dissenting stockholders to change their votes to votes in favor of Proposals 2.

The Concerned Signature Stockholders are against the approval of this proposal and recommend a vote AGAINST this proposal. It is difficult to imagine a situation where it would be necessary or appropriate for the Company to adjourn the 2013 Annual Meeting where a quorum of shares are present to seek votes to approve Proposal 2 if these proposals have already been rejected by stockholders. If the Company cannot obtain sufficient stockholder support for Proposal 2 by the time of the originally scheduled 2013 Annual Meeting, it should not be able to move the 2013 Annual Meeting in order to keep seeking such support. We believe approval of this proposal would effectively allow the Board to bypass the will of stockholders and further waste Company resources in an effort to pass proposals stockholders have already rejected.

THE CONCERNED SIGNATURE STOCKHOLDERS OPPOSE PROPOSAL 6 AND RECOMMEND THAT STOCKHOLDERS VOTE “AGAINST” APPROVAL OF THE PROPOSAL TO ADJOURN THE 2013 ANNUAL MEETING IF PROPOSAL 2 IS NOT PASSED.

VOTING AND PROXY PROCEDURES

Only stockholders of record at the close of business on the Record Date will be entitled to notice of and to vote at the 2013 Annual Meeting. Each share of the Company’s Common Stock is entitled to one vote. Stockholders who sold any shares before the Record Date (or acquire them without voting rights after the Record Date) may not vote such shares. Stockholders of record on the Record Date will retain their voting rights in connection with the 2013 Annual Meeting even if they sell their shares of the Company’s common stock after the Record Date. Based on publicly available information, the Concerned Signature Stockholder believe that the only outstanding class of securities of the Company entitled to vote at the 2013 Annual Meeting is the common stock of the Company.

Shares represented by properly executed GOLD Proxy Cards will be voted at the 2013 Annual Meeting as marked and, in the absence of specific instructions, will be voted FOR the election of the Concerned Stockholder Nominees to the Board, AGAINST approval of the Articles Amendment, FOR the ratification of the appointment of Squar Milner as the independent registered public accounting firm for the fiscal year ended December 31, 2013, AGAINST approval of the Executive Compensation, for ONE YEAR between future stockholder advisory votes on Executive Compensation, and AGAINST the Adjournment Proposal and in the discretion of the persons named as proxies on all other matters as may properly come before the 2013 Annual Meeting.

The Board is currently composed of five directors, whose terms expire at the 2013 Annual Meeting. If elected, the Concerned Stockholder Nominees will represent all members of the Board. The Concerned Signature Stockholders are soliciting proxies to elect only the Concerned Stockholder Nominees. Accordingly, the enclosed GOLD Proxy Card may only be voted for the Concerned Stockholder Nominees and does not confer voting power with respect to any of the Company’s director nominees. Stockholders who return the GOLD Proxy Card will only be able to vote for the Concerned Stockholder Nominees. You can only vote for the Company’s director nominees by signing and returning a Proxy Card provided by the Company.

12

QUORUM; DISCRETIONARY VOTING

A majority of the issued and outstanding shares of the Company’s common stock entitled to vote at an annual meeting of stockholders, represented either in person or by proxy, is necessary to constitute a quorum for the transaction of business at the 2013 Annual Meeting. Shares of the Company’s common stock that are voted “WITHHOLD” in the election of directors or “ABSTAIN” on any other proposal will be treated as being present for purposes of determining the presence of a quorum. Unless beneficial owners of shares of the Company’s common stock held by brokers, banks or nominees (i.e., in “street name”) provide instructions on how to vote, such shares may not be voted by such brokers, banks or nominees on, and will be considered a “broker non-vote” in respect of, the proposals due to the contested nature of the 2013 Annual Meeting.

VOTES REQUIRED FOR APPROVAL; ABSTENTIONS

Proposal 1 - Vote required for the election of directors. According to the Company Statement and Bylaws, in a contested election, directors will be elected by a plurality of votes cast. Under the plurality standard, the only votes that count when director votes are being tabulated are “FOR” votes. “Withhold” votes and broker non-votes have no effect on the vote required for the election of directors.

Proposal 2 - Vote required for approval of the Articles Amendment. According to the Company Statement, the affirmative vote of the holders of a majority of the outstanding shares of the Company’s common stock is needed to approve the Articles Amendment. Therefore, the failure to vote, either by proxy or in person, an abstention or a broker non-vote will all have the same effect as a vote against the approval of this proposal.

Proposal 3 - Vote required for the ratification of the selection of Squar Milner. According to the Company Statement, to ratify the selection of Squar Milner, more votes must be cast FOR Proposal 3 than are cast AGAINST Proposal 3. The failure to vote, either by proxy or in person, will not have an effect on this proposal. Abstentions and broker non-votes will not be counted as votes cast and, therefore, will not affect this proposal.

Proposal 4 - Vote required for approval of Executive Compensation. According to the Company Statement, to approve the advisory vote on Executive Compensation, more votes must be cast FOR Proposal 4 than are cast AGAINST Proposal 4. The failure to vote, either by proxy or in person, will not have an effect on this proposal. Abstentions and broker non-votes will not be counted as votes cast and, therefore, will not affect this proposal.

Proposal 5 - Vote required for the frequency of stockholder advisory votes on Executive Compensation. According to the Company Statement, the frequency (i.e., every one, two or three years) receiving the most cast for Proposal 5 is needed to select a frequency of stockholder advisory votes on Executive Compensation. The failure to vote, either by proxy or in person, will not have an effect on this proposal. Abstentions and broker non-votes will not be counted as votes cast and, therefore, will not affect this proposal.

Proposal 6 - Vote required for the Adjournment Proposal. According to the Company Statement, to approve the Adjournment Proposal, more votes must be cast FOR Proposal 6 than are cast AGAINST Proposal 6. The failure to vote, either by proxy or in person, will not have an effect on this proposal. Abstentions and broker non-votes will not be counted as votes cast and, therefore, will not affect this proposal.

REVOCATION OF PROXIES

Stockholders of the Company may revoke their proxies at any time prior to exercise by attending the 2013 Annual Meeting and voting in person (although attendance at the 2013 Annual Meeting will not in and of itself constitute revocation of a proxy) or by delivering a written notice of revocation. The delivery of a subsequently dated proxy that is properly completed will constitute a revocation of any earlier proxy. The revocation may be delivered either to the Concerned Signature Stockholders in care of Morrow & Co., LLC at the address set forth on the back cover of this Proxy Statement or to the Company at 15303 Ventura Blvd., Suite 1600, Sherman Oaks, CA 91403 or any other address provided by the Company.

Although a revocation is effective if delivered to the Company, the Concerned Signature Stockholders request that either the original or xerox copies of all revocations be mailed or faxed to the Concerned Signature Stockholders in care of Morrow & Co., LLC at the address set forth on the back cover of this Proxy Statement so that the Concerned Signature Stockholders will be aware of all revocations and can more accurately determine if and when proxies have been received from the holders of record of a majority of the outstanding shares of the Company’s common stock on the Record Date. Additionally, Morrow & Co., LLC may use this information to contact stockholders who have revoked their proxies in order to solicit later dated proxies for the election of the Concerned Stockholder Nominees.

CERTAIN EFFECTS OF THIS PROXY STATEMENT

Based upon a review of the Company’s public filings with the SEC, the election of the Concerned Stockholder Nominees to the Board may result in a “Change in Control” under a number of agreements with various Company executives (the “Executive Agreements”). The definition of “Change in Control” in these agreements includes replacing a majority of members on the Board with directors not endorsed by a majority of Board then in place. Upon a Change in Control, according to the provisions of the Executive Agreements, the following Company restricted shares and options to purchase share of the Company held by the following employees would immediately vest: Kenneth S. Grossman (492,224 shares and options for 1,461,500 shares), Kyle C. Ross (416,667 shares and options for 1,310,000 shares), Thomas J. Donatelli (378,788 shares and options for 1,350,000 shares) and W. Christopher Manderson (195,000 shares and options for 756,000 shares). Further, upon such a Change in Control, the 492,224 Company restricted shares and options for the purchase of 1,461,500 shares held by Craig F. Noell pursuant to the Settlement Agreement and General Release, dated April 9, 2013, by and between the Company and Mr. Noell, would immediately vest.

In addition, the Amended and Restated Signature Group Holdings, Inc. 2006 Performance Incentive Plan (the “Plan”) provides that, unless otherwise provided in a participant’s employment or other agreement with the Company, the administrators of the Plan may accelerate the vesting of any outstanding options, stock appreciation rights or restricted stock awards. The definition of Change in Control under the Plan specifically includes a change in the composition of the Board such that incumbent directors constitute less than a majority of the new Board; the election of the Concerned Stockholder Nominees would satisfy this definition. As reported in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, 809,122 shares of restricted stock and options to purchase 14,215 shares issued under the plan were unvested as of December 31, 2012.

The election of the Concerned Stockholder Nominees would also trigger a provision of the Company’s Rights Agreement, dated October 23, 2007 (the “Rights Agreement”). If a majority of the Board not nominated by the current Board is elected, then the Rights issued pursuant to the Rights Agreement may not be redeemed for 180 days following the seating of the new Board majority.

We have not independently verified if the copies of the Executive Agreements, the Plan or the Rights Agreement (collectively, the “Filed Agreements”) publicly filed by the Company with the SEC are the same as the executed copies of the Filed Agreements, and the analyses above are based on our review of the Company’s public SEC filings. Other compensation or vesting provisions with other Company employees or directors may be triggered by a change in control. If the Company’s stockholders approve the election of the Concerned Stockholder Nominees, prior to the acceleration of vesting of any Company equity awards or the payment of any compensation or tax gross-up, we expect to review with counsel the original copies of all relevant agreements, award documentation and Company records associated with the creation of the potential obligations upon a change in control.

STOCKHOLDER PROPOSALS TO BE PRESENTED AT NEXT ANNUAL MEETING

Any stockholder wishing to submit a proposal to be included in the Company’s 2014 proxy statement pursuant to Rule 14a-8 of the Exchange Act must submit such proposal in writing to the Company’s Secretary at the Company’s principal executive offices located at 15303 Ventura Boulevard, Suite 1600, Sherman Oaks, California 94103. The Company must receive such a proposal no later than January 9, 2014.

Stockholder proposals not made pursuant to Rule 14a-8 must comply with the advance notice provisions contained in the Bylaws which provide that such proposals must be submitted in writing to, and received by, the Company’s Secretary at the Company’s principal executive offices located at 15303 Ventura Boulevard, Suite 1600, Sherman Oaks, California 94103 no later than March 30, 2014, unless the date of the annual meeting is advanced more than 30 days prior to or delayed by more than 30 days after the anniversary of the 2013 Annual Meeting. In that case, the Company’s secretary must receive proposals not later than the close of business on the later of (i) the 75th day prior to such annual meeting or (ii) if no annual meeting of stockholders was held the previous year, no later than ten (10) days following the date notice of the annual meeting is first given. To be in proper form, a stockholder’s notice must include the specified information concerning the proposal as described in the Bylaws.

The information set forth above regarding the procedures for submitting stockholder proposals for consideration at the 2012 Annual Meeting is based on information contained in the Company Statement.
