PROXY STATEMENT OF DISCOVERY EQUITY PARTNERS, L.P., DISCOVERY GROUP I, LLC,
DANIEL J. DONOGHUE AND MICHAEL R. MURPHY

January [  ], 2009

To Tier Technologies, Inc. Stockholders:

Discovery Equity Partners, L.P. (“Discovery Equity Partners”), Discovery Group I, LLC (“Discovery Group I”), Daniel J. Donoghue and Michael R. Murphy (collectively, the “Discovery Group”) are furnishing this Proxy Statement to holders of the common stock, $0.01 par value (“Common Stock”), of Tier Technologies, Inc., a Delaware corporation (the “Company” or “Tier”), in connection with our solicitation of proxies for use at the 2009 Annual Meeting of Stockholders of the Company and at any and all adjournments or postponements thereof (the “Stockholder Meeting”).  The Company has stated that the Stockholder Meeting will be held at the headquarters of the Company, 10780 Parkridge Boulevard, Reston, Virginia, on Wednesday, March 11, 2009, at 10:00 a.m., Eastern Standard Time.  The Board of Directors of the Company (the “Board of Directors” or the “Board”) has fixed the close of business on January 16, 2009 as the record date for determining the stockholders entitled to receive notice of, to attend, and to vote at the Stockholder Meeting.  This Proxy Statement and the accompanying WHITE proxy card are first being sent or given to stockholders of the Company on or about January [  ], 2009.

This solicitation is being conducted by the Discovery Group.  The Discovery Group beneficially owns approximately 9.9% of the Common Stock reported by the Company as outstanding as of November 28, 2008.  As more fully discussed below, the Discovery Group is soliciting proxies to be used at the Stockholder Meeting for the following actions:

(1)                                  To elect Mr. Daniel J. Donoghue and Mr. Michael R. Murphy as directors of the Company (collectively, the “Discovery Group Nominees”);

(2)                                  To ratify the selection of McGladrey & Pullen, LLP as the Company’s independent registered public accounting firm for the fiscal year ending September 30, 2009;

(3)                                  To approve a stockholder proposal submitted by Discovery Equity Partners to the Company under SEC Rule 14a-8 that requests that the Board of Directors restore to stockholders their rights to directly influence the strategic direction and possible sale of the Company by (i) terminating the Company’s “poison pill” rights plan and (ii) reinstating the ability of stockholders owning at least 10% of the voting power to call special meetings of stockholders.

According to the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2008, there were 19,734,463 shares of Common Stock outstanding as of November 28, 2008.  The Company’s stockholders are entitled to one vote per share of Common Stock.  However, the Company’s certificate of incorporation provides that stockholders have cumulative voting rights with respect to the election of directors.  Cumulative voting rights entitle you to give a nominee as many votes as is equal to the number of shares you own multiplied by the number of directors to be elected, or you may distribute your votes among the nominees as you see fit.

We are soliciting the discretionary authority to cumulate votes, and the persons named as proxies on our proxy card will have the authority to cumulate votes at their discretion.  We will use the authority granted to us by our WHITE proxy card to cumulate votes for the Discovery Group Nominees to assure that the maximum number of Discovery Group Nominees are elected to the Board of Directors.

We urge you to elect the Discovery Group Nominees to the Board of Directors because we believe that the election of new members to the Board would be beneficial to the Company and its stockholders.  The Discovery Nominees have extensive experience as executives of financial institutions, advisors to public and private companies, founders of a successful investment firm, publishers of research on small capitalization public companies, valuation experts and leaders of M&A transactions.  Discovery Group’s investment of approximately $16 million in the Company aligns the interests of the Discovery Group Nominees with all fellow stockholders.  The Discovery Group Nominees intend to bring the perspective of a large investor to the Board and will seek to work constructively with the other members of the Board, as well as the existing Tier management team.  The Discovery Nominees hope to help the Company expeditiously to reduce what the Discovery Group believes is excessive overhead, to determine if Company capital should be returned to stockholders, to eliminate any unnecessary corporate takeover defenses, and to proactively evaluate all strategic alternatives to unlock the value of the Company’s Electronic Payment Processing (“EPP”) business for stockholders.

Accordingly, we urge you to sign and date the WHITE proxy card supplied by the Discovery Group and return it in the enclosed postage-paid envelope, whether or not you plan to attend the meeting, in order to vote:

(A) “FOR” the election of Daniel J. Donoghue and Michael R. Murphy to the Board of Directors,

(B) “FOR” the ratification of the selection of McGladrey & Pullen, LLP as the Company’s independent registered public accounting firm for the fiscal year ending September 30, 2009, and

(C) “FOR” the stockholder proposal (the “Stockholder Proposal”) requesting that the Company’s Board of Directors restore to stockholders their rights to directly influence the strategic direction and possible sale of the Company by (i) terminating the Company’s “poison pill” rights plan and (ii) reinstating the ability of stockholders owning at least 10% of the voting power to call special meetings of stockholders.

If your shares are held in the name of a brokerage firm, bank or nominee, only that entity can vote such shares and only upon receipt of your specific instruction.  Accordingly, we urge you to contact the person responsible for your account and instruct that person to execute the WHITE proxy card on your behalf.

YOUR VOTE IS IMPORTANT.  If you agree with the reasons for the Discovery Group’s solicitation set forth in this Proxy Statement and believe that the election of the Discovery Group Nominees to the Board of Directors and the adoption of the Stockholder Proposal can make a difference,

2

please vote for the election of the Discovery Group Nominees and the adoption of the Stockholder Proposal, no matter how many or how few shares you own.

THE DISCOVERY GROUP URGES YOU NOT TO SIGN ANY PROXY CARD THAT IS SENT TO YOU BY THE COMPANY, EVEN AS A FORM OF PROTEST.  By executing the WHITE proxy card, you will authorize us to vote FOR the election of the two Discovery Group Nominees and for the Stockholder Proposal.  If you have already signed a proxy card sent to you by the Company, you may revoke that proxy at any time prior to the time a vote is taken by (i) submitting a duly executed proxy bearing a later date to the Secretary of the Company, (ii) filing with the Secretary of the Company a later dated written revocation or (iii) attending and voting at the Stockholder Meeting in person.

GENERAL

The Board of Directors currently consists of eight directors who serve for a one year term.  According to the Company’s proxy statement (the “Company Proxy Statement”), filed in preliminary form on January [  ], 2009, [eight] directors are to be elected to the Board of Directors at the Stockholder Meeting, to hold office until their successors have been elected and qualified.  The Company has nominated [the eight current members of the Board] to stand for re-election at the Stockholder Meeting (the “Company Nominees”).

We are currently seeking your proxy for the election to the Board of Directors of two individuals - Mr. Daniel J. Donoghue and Mr. Michael R. Murphy.  We are soliciting the discretionary authority to cumulate votes, and the persons named as proxies on our proxy card will have the authority to cumulate votes at their discretion.  We will use the authority granted to us by our WHITE proxy card to cumulate votes for the Discovery Group Nominees to assure that the maximum number of Discovery Group Nominees are elected to the Board of Directors.  We are also seeking your proxy to vote for the Stockholder Proposal and for the ratification of the selection of McGladrey & Pullen, LLP as the Company’s independent registered public accounting firm for the fiscal year ending September 30, 2009

For information concerning voting procedures at the Stockholder Meeting, see “Voting and Proxy Procedures.”

BACKGROUND OF THIS SOLICITATION

The Discovery Group has been a stockholder of the Company since March 2007.  The Discovery Group acquired shares of common stock through open market purchases as part of its proprietary investment strategy and, as of the date of this Proxy Statement, the Discovery Group beneficially owns 1,957,563 shares of Common Stock, representing approximately 9.9% of the outstanding Common Stock.  1,684,608 of the shares of Common Stock beneficially owned by the Discovery Group are owned directly by Discovery Equity Partners, and the remaining 272,955 shares of Common Stock beneficially owned by the Discovery Group are owned directly by another investment partnership. (the “Other Partnership”) for which Discovery Group I is the investment manager and over which shares Discovery Group I exercises discretionary investment management authority.

In connection with its investment in the Company, the Discovery Group reviews the Company’s business affairs, financial position, management, capital structure, and future plans on an ongoing basis.  In addition, as part of its review, representatives of the Discovery Group have held meetings and telephone conversations with the Company’s management, directors, other stockholders, and other interested parties, including companies and other institutions having operations in the electronic payments industry, regarding the Company’s performance, its business plan and strategic alternatives available to it.

On May 12, 2008, the Discovery Group filed a Schedule 13D with the Securities and Exchange Commission (the “SEC”) indicating that we had acquired 5.8% of the outstanding Common Stock.  In the Schedule 13D, the Discovery Group indicated that it had acquired such shares of Common Stock because of its belief that the trading prices of the Common Stock do not adequately reflect the potential value of the Company’s underlying business and assets.  The Discovery Group indicated that it had held meetings with certain members of the Company’s management and directors and had also sent written communication to the entire Board of Directors, and that during these meetings and correspondences, the Discovery Group had expressed certain recommendations to the Company, including a strong desire for the Board of Directors to engage an investment bank to explore all strategic alternatives available to the

4

Company, including the potential sale of the Company.  The Schedule 13D indicated that the Discovery Group’s recommendations were based on (i) discussions with large transaction processing companies expressing an interest in acquiring the Company, (ii) a competitive takeover valuation that will provide a significant premium to the Company’s current stock price, (iii) competitive threats to the Company from larger, more efficient industry participants, and (iv) obstacles that will prevent the Company from achieving a significant increase in shareholder value on a stand-alone basis, including senior management turnover, an extremely high cost structure, and the Company’s lack of credibility with public investors.

On June 9, 2008, representatives of the Discovery Group made a presentation by conference call to two members of the Company’s Board of Directors.  In addition to reiterating the recommendation that the Board engage an investment bank and explore strategic alternatives, the Discovery Group representatives presented the Board members with feedback from informal discussions with several large Company investors, wherein the investors had expressed the view that they were disappointed with the performance of management of the Company, had a strong desire to for the Board to authorize the Company to repurchase shares, and would like to see the Company sold to a strategic buyer.

On September 9, 2008, Discovery Equity Partners submitted to the Company the Stockholder Proposal under SEC Rule 14a-8 for inclusion in the Company’s proxy statement for the Company’s 2009 Annual Meeting of Stockholders.

On October 28, 2008, Discovery Equity Partners received a letter dated October 27, 2008 from the Vice President and General Counsel of the Company stating that the Company had no record of having received the Stockholder Proposal.

On October 30, 2008, Discovery Equity Partners sent a letter to the Vice President and General Counsel of the Company providing detailed evidence that Discovery Equity Partners’ proposal was properly submitted to the Company in the manner and within the time period required by SEC Rule 14a-8, and that representatives of the Company have been aware of the submission of such proposal since the time of such submission.  It is the understanding of Discovery Equity Partners that the Company intends to include the Stockholder Proposal in the Company Proxy Statement.

On December 4, 2008, Discovery Equity Partners delivered to the Company notice under the Company’s bylaws of Discovery Equity Partners’ intention to nominate the Discovery Group Nominees for election at the Stockholder Meeting.

Also on December 4, 2008, Discovery Equity Partners delivered to the Company a letter addressed to the Board of Directors setting forth certain of its reasons for its intention to nominate the Discovery Group Nominees.  The Discovery Group also issued a press release with respect to its intention to nominate the Discovery Group Nominees.

On December 17, 2008, Discovery Equity Partners sent to the Company a written request as permitted by the Delaware General Corporation Law with respect to the inspection and use of the Company’s stockholders list and related materials in connection with the solicitation of proxies for Stockholder Meeting.  On December 23, 2008, the Company sent to Discovery Equity Partners a letter agreeing to provide such materials subject to Discovery Equity Partners entering into a confidentiality agreement with respect to the use and disclosure thereof, and agreeing to pay certain costs of the Company in connection with the production thereof.

On January 9, 2009, the Discovery Group filed a preliminary version of this Proxy Statement with the SEC.

REASONS FOR THIS SOLICITATION

We expect that the Discovery Group Nominees, if elected, would bring the fresh perspective of a large investor to the Board of Directors.  We believe that the Discovery Group Nominees, if elected, can work with the other members of the Board of Directors to:

·                  expeditiously reduce what the Discovery Group believes is excessive overhead at the Company,

·                  promptly return to stockholders what the Discovery Group believes is the Company’s excess capital,

·                  eliminate any unnecessary corporate takeover defenses, and

·                  proactively evaluate all strategic alternatives to unlock the value of the Company’s EPP business for stockholders.

However, there can be no assurance that the Discovery Group Nominees and the Board of Directors will succeed in creating stockholder value.

Under Delaware corporate law, the Board of Directors is charged with the management of the Company, including determining its strategic direction.  The Discovery Group believes that if the Discovery Group Nominees are elected, they would be in a position as directors of the Company to influence the strategic direction of the Company by bringing to the Board the perspective of a significant stockholder.  The Discovery Group believes that a major issue with the existing Board and Company management is that there is a significant misalignment between their interest and that of the Company’s stockholders, since no director or officer beneficially owns more than 3% of the outstanding stock, and the ownership level of this group is de minimis if unexercised options and restricted stock units are excluded from the calculation.

As members of the Board of Directors, the Discovery Group Nominees would be able to present initiatives to the entire Board of Directors, actively participate in Board discussions and argue in support of positions that they believe would benefit the Company’s stockholders.  If elected, the Discovery Group Nominees would have greater access to Company information and management, which would allow them to be more knowledgeable and effective advocates in favor of these positions.  While the Discovery Group Nominees will not constitute a majority of the Board of Directors, the Discovery Group Nominees believe that the other directors of the Company will, in the discharge of their fiduciary duties under Delaware law, consider all reasonable proposals to enhance stockholder value by exploring these proposals and acting on them if they determine that such proposals are in the best interests of the Company’s stockholders.

The Discovery Group Nominees believe that the following matters should be addressed by the Board of Directors as soon as possible and, if elected, the Discovery Group Nominees will work to have the Board address them.

Corporate Overhead.  The Discovery Group Nominees believe that the Board of Directors has sanctioned what the Discovery Group Nominees think is an excessive level of corporate overhead, given the Company’s revenue base and profitability.  If the Company is to become profitable, the Discovery Group Nominees believe its level of corporate overhead must be reduced rapidly and significantly.

6

This is illustrated by information in the Company’s recently issued Annual Report for the fiscal year ended September 30, 2008 (the “2008 Annual Report”).  In the Annual Report, the costs and expenses attributed to “Corporate & Eliminations” (which the Company describes as “corporate overhead and other costs that could not be directly assigned to our EPP operations or to our Discontinued Operations, as well as eliminations for transactions between our Continuing and Discontinued Operations”) are shown as $27.2 million, $16.6 million and $16.8 million for fiscal years 2006, 2007 and 2008, respectively.  These costs have contributed materially to the amount of the Company’s reported loss from continuing operations for those same years of $(19.6) million, $(18.4) million and $(12.0) million.

While the Company has sought to somewhat decrease corporate overhead, the Company’s Chief Executive Officer has publicly stated that corporate overhead would only be reduced to a run rate of $10 million at the end of fiscal year 2009 (with projected corporate overhead of approximately $12 million for the full 2009 fiscal year) and a run rate of $9 million at the end of fiscal year 2010.  Even if these projections are achieved, the reduction in overhead seems inadequate.  The Company’s EPP business is now the Company’s predominant business (the 2008 Annual Report indicates that the Company’s only other business is one remaining Packaged Software Systems Integration operation for which it continues to seek a buyer) and the EPP business’ stand-alone Income from Continuing Operations for 2008, 2007 and 2006 was only $3.2 million, $5.9 million and $5.6 million, respectively, as reported in the 2008 Annual Report.  Thus, even if the Company’s corporate overhead projection is achieved, the run rate for corporate overhead for at the end of 2009 would still exceed EPP’s 2008 income by more than 3 times.

In the view of the Discovery Group Nominees, the current level of corporate overhead is unsustainable and must be reduced rapidly, and the Discovery Group Nominees plan to work with the Board and Company management to seek ways to effect such a reduction.

Return of Capital to Stockholders.  The Company’s cash balance has grown materially and steadily since the end of fiscal year 2000, when it stood at $19.9 million.  At the end of fiscal year 2008, the Company’s cash balance (including cash invested in auction rate securities that were reclassified by the Company as a long-term investment because of market illiquidity and in restricted investments) was approximately $87 million.  This increase in cash was not sudden, as the Company’s reported cash balance, when compared with the cash balance at the prior fiscal year-end, increased for fiscal years 2001, 2002, 2004, 2005, 2007 and 2008.  The Company now holds more than $4.50 per share in cash, including its ill-timed investments in auction rate securities that are now illiquid.  The Discovery Group Nominees believe that the Board of Directors should consider whether this level of cash is actually needed for the Company’s operations and the implementation of its business plan, and if not, whether the Company should return a portion of such cash to stockholders through share repurchases or a special dividend or other means.

Takeover Defenses.  In January 2006, the Company adopted a “poison pill” stockholder rights plan that the Discovery Group Nominees believe effectively prevents any person from acquiring 15% or more of the outstanding common stock without the Board’s consent and also adopted a Bylaw amendment that denied stockholders the right to call special meetings.  These actions appear to have been taken in response to Tier’s widely reported operating and accounting problems at the time.  The Discovery Group Nominees believe that the Board of Directors should now have the confidence to reverse the defensive mechanisms then adopted, since in the opinion of the Discovery Group Nominees, they no longer serve the best interests of the Company and its stockholders and represent a de facto transfer of voting rights away from stockholders to management.  The Discovery Group Nominees believe that poison pills reduce accountability and entrench management, prevent investors from making financially meaningful investments in small capitalization companies like the Company, and allow a board of directors unilaterally to block offers for a company that are in the best interests of stockholders.  In addition, in the opinion of the Discovery Group Nominees, if a company’s board of directors and

7

management have no meaningful equity stake (as the Discovery Group Nominees believe is the case with the Company), this creates a significant conflict of interest between the board of directors and stockholders.  The Discovery Group Nominees note that in response to stockholder complaints, numerous companies have terminated or not renewed their poison pills.  The Discovery Group Nominees also believe that the elimination of the right of stockholders to call special meetings limits the direct voice of stockholders in the Company’s strategic direction by allowing management to unilaterally decide if a proposal may be presented to stockholders between annual meetings, and that for a rapidly changing business, annual meetings do not provide the access necessary for stockholders to bring forward and vote on critical and timely matters while the company is undergoing such transformations.  The Discovery Group Nominees, if elected, will seek to cause the Board to implement the Stockholder Proposal.

Strategic Alternatives.  The Discovery Group Nominees believe that the Company’s EPP business has significant value.  They also believe that one strategy to unlock the value of the EPP business is to sell Tier to one of the many strategic parties that are potentially interested in acquiring the business since a strategic buyer could reduce the effect of the Company’s corporate overhead on EPP’s profitability and potentially augment the EPP business’ growth and profitability in other ways.  The Discovery Group Nominees believe that because of these benefits to a buyer, the right transaction could deliver a premium to the Company’s stockholders.  The Discovery Group Nominees, if elected, will seek to cause the Board to eliminate any impediments to the evaluation of potential transactions with interested parties.

---------------------------------------

The Discovery Group Nominees will constitute [twenty five] percent of the Board of Directors if they are elected and, therefore, even if they vote unanimously, will not be able to adopt any measures without the support of other members of the Board of Directors.  Depending on the responsiveness of the Board to any proposals or initiatives presented by the Discovery Group Nominees, the Discovery Group may seek to nominate additional directors independent of both the Company and the Discovery Group to the Board of Directors at the Company’s 2010 annual meeting if the Discovery Group believes that additional representation on the Board would make Discovery Group Nominees’ efforts more effective.

The Discovery Group Nominees do not anticipate that they will have any conflicts of interest with respect to the Company, if elected, and recognize their fiduciary duty obligations to all stockholders.  None of the Discovery Group Nominees has any contract, arrangement or understanding with the Company, and no other direct financial interest concerning the Company, other than through the beneficial ownership of Common Stock by the Discovery Group as disclosed in this Proxy Statement.

THE DISCOVERY GROUP RECOMMENDS A VOTE FOR THE ELECTION OF THE DISCOVERY GROUP NOMINEES BECAUSE THEY BELIEVE THAT THE DISCOVERY GROUP NOMINEES WOULD CONTRIBUTE TO THE CREATION OF STOCKHOLDER VALUE.

MATTERS TO BE CONSIDERED AT THE STOCKHOLDER MEETING

PROPOSAL 1: ELECTION OF DIRECTORS

The Board of Directors currently consists of eight directors.  Directors hold office until the Company’s next annual meeting and until their successors are elected and qualified, unless prior to that time they have resigned, retired or otherwise left office.  According to the Company Proxy Statement, [eight] directors are to be elected to the Board at the Stockholder Meeting.  By letter dated December 3,

8

2008, Discovery Equity Partners gave notice to the Company of its intention to nominate the Discovery Group Nominees to serve as directors of the Company.

We are seeking your proxy for the election to the Board of Directors of two individuals - Mr. Daniel J. Donoghue and Mr. Michael R. Murphy.  We are soliciting the discretionary authority to cumulate votes, and the persons named as proxies on our proxy card will have the authority to cumulate votes at their discretion.  We will use the authority granted to us by our WHITE proxy card to cumulate votes for the Discovery Group Nominees to assure that the maximum number of Discovery Group Nominees are elected to the Board of Directors.  Under applicable proxy rules, we are required either to solicit proxies only for Messrs. Donoghue and Murphy, or to solicit proxies for Messrs. Donoghue and Murphy and for such number of the Company Nominees as equal the number of director positions then subject to election.  Our decision to solicit proxies only for Messrs. Donoghue and Murphy will result in limiting ability of stockholders who use the WHITE proxy card to exercise their voting rights with respect to the Company Nominees.

Each of the Discovery Group Nominees has consented to being named as a nominee in this Proxy Statement and to serve as a director of the Company, if elected.  The Discovery Group does not expect that either of the Discovery Group Nominees will be unable to stand for election, but in the event that any of Discovery Group Nominees is unable to stand for election or to serve for any reason, including by reason of the taking or announcement of any action by the Company that has, or if consummated would have, the effect of disqualifying any such Discovery Group Nominee from serving as a director, any shares of Common Stock represented by the WHITE proxy card will be voted for a substitute candidate selected by the Discovery Group.

PROPOSAL 3:                               APPROVAL OF THE STOCKHOLDER PROPOSAL

According to the Company Proxy Statement, the Company has submitted for the consideration of stockholders the Stockholder Proposal submitted by Discovery Equity Partners to the Company under Rule 14a-8.  The Stockholder Proposal, including Discovery Equity Partner’s Supporting Statement, reads as follows:

Stockholder Proposal

RESOLVED, that the stockholders of Tier Technologies, Inc. (“Tier”) request that Tier’s Board of Directors restore to stockholders their rights to directly influence the strategic direction and possible sale of Tier by (i) terminating Tier’s “poison pill” rights plan and (ii) reinstating the ability of stockholders owning at least 10% of the voting power to call special meetings of stockholders.

Supporting Statement

In January 2006, the Board of Tier stripped its stockholders, without their consent, of their ability to directly receive offers for Tier by implementing a poison pill that effectively prevents any person from acquiring 15% or more of the outstanding common stock without the Board’s consent.  Further, the Board eliminated the ability of stockholders to pursue value-creation proposals between annual meetings by denying stockholders the right to call special meetings.  These actions appear to have been taken in response to Tier’s widely reported operating and accounting problems.

Nearly three years have passed since these events and Tier is no longer the poorly integrated collection of weak performing businesses with inadequate financial controls that it then was.  The Board should now have the confidence to reverse the defensive mechanisms then adopted, since they no longer serve the best interests of Tier and its stockholders and represent a de facto transfer of voting rights away from stockholders to management.

Poison pills reduce accountability and entrench management, prevent investors from making financially meaningful investments in small capitalization companies like Tier, and allow a Board unilaterally to block offers for a company that are in the best interests of stockholders.  If a company’s Board and management have no meaningful equity stake (as is the case with Tier), this creates a significant conflict of interest between the Board and stockholders.  Recently, in response to stockholder complaints, numerous companies have terminated or not renewed their poison pills.  Tier’s Board should remove its obsolete poison pill that currently acts as an impediment to realizing shareholder value.

The elimination of the right of stockholders to call special meetings limits the direct voice of stockholders in Tier’s strategic direction by allowing management to unilaterally decide if a proposal may be presented to stockholders between annual meetings. Tier is rapidly changing its Board composition, its management team, its operations, and its overall strategic direction.  Annual meetings do not provide the access necessary for shareholders to bring forward and vote on critical and timely matters while the company is undergoing such transformations.

By supporting this proposal, stockholders can advise the Board of their concerns regarding Tier’s continued maintenance of defenses against offers and proposals that may maximize shareholder value, and express their desire that the Board be open to all strategic alternatives for Tier, including its sale.  While the adoption of this proposal will

12

not legally bind the Board, we trust that given its fiduciary responsibilities, the Board will honor the stockholders’ wishes as reflected in the vote on the proposal.

Discovery, one of Tier’s largest shareholders, strongly urges you to vote FOR this proposal.

According to the Company Proxy Statement, the Board of Directors has unanimously recommended a vote [against] the Stockholder Proposal.  Please refer to the Company Proxy Statement for the Board’s arguments regarding the Stockholder Proposal.

For the reasons stated above, the Discovery Group recommends that stockholders vote FOR the Stockholder Proposal.  We urge you to vote FOR the Stockholder Proposal on the WHITE proxy card.  If you do not indicate any voting instruction, we will vote the WHITE proxy card FOR the Stockholder Proposal.

Except as set forth in this Proxy Statement, the Discovery Group is not aware of any other matter to be considered at the Stockholder Meeting.  However, if the Discovery Group learns of any other proposals made at a reasonable time before the Stockholder Meeting, the Discovery Group will either supplement this Proxy Statement and provide an opportunity to stockholders to vote by proxy directly on such matter or will not exercise discretionary authority with respect thereto.  If other proposals are made thereafter (including at the Stockholder Meeting), the persons named as proxies on the WHITE proxy card solicited by the Discovery Group will vote such proxies in their discretion.

VOTING AND PROXY PROCEDURES

The Discovery Group believes that it is in the best interest of the Company’s stockholders to elect the Discovery Group Nominees and to approve the Stockholder Proposal at the Stockholder Meeting.  THE DISCOVERY GROUP RECOMMENDS A VOTE FOR THE ELECTION OF THE DISCOVERY GROUP NOMINEES AND FOR THE APPROVAL OF THE STOCKHOLDER PROPOSAL BECAUSE THE DISCOVERY GROUP BELIEVES THAT SUCH ACTIONS WOULD CONTRIBUTE TO THE CREATION OF STOCKHOLDER VALUE.

HOW DO I VOTE BY PROXY?

For the proxy solicited hereby to be voted, the WHITE proxy card to be supplied by the Discovery Group Nominees must be signed, dated and returned to the Discovery Group, c/o The Altman Group, in the enclosed postage-paid envelope in time to be voted at the Stockholder Meeting.  If you wish to vote for the Discovery Group Nominees, you must submit the WHITE proxy card supplied by the Discovery Group and must NOT submit the Company’s proxy card.  While the Company’s proxy card can be voted for the Stockholder Proposal, it CANNOT be voted for the Discovery Group Nominees.

WHAT IF I AM NOT THE RECORD HOLDER OF MY SHARES?

If your shares are held in the name of a brokerage firm, bank or nominee, only that entity can vote such shares and only upon receipt of your specific instruction.  Accordingly, we urge you to contact the person responsible for your account and instruct that person to execute on your behalf the WHITE proxy card.  If you hold your shares through a brokerage firm, bank or nominee and wish to vote your shares in person at the Stockholder Meeting, you must obtain a legal proxy from such custodian in order to vote in person at the Stockholder Meeting.

IF I PLAN TO ATTEND THE STOCKHOLDER MEETING, SHOULD I STILL SUBMIT A WHITE PROXY?

Whether or not you plan to attend the Stockholder Meeting, we urge you to submit a WHITE proxy card.  Returning the enclosed proxy card will not affect your right to attend and vote at the Stockholder Meeting.

WHAT IF I WANT TO REVOKE MY PROXY?

Any proxy may be revoked as to all matters covered thereby at any time prior to the time a vote is taken by (i) submitting a duly executed proxy bearing a later date to the Secretary of the Company, (ii) filing with the Secretary of the Company a later dated written revocation or (iii) attending and voting at the Stockholder Meeting in person.  Attendance at the Stockholder Meeting will not in and of itself constitute a revocation.

15

Please note that if you hold your shares through a brokerage firm, bank or nominee and wish to revoke your proxy, you must follow the instructions provided by that brokerage firm, bank or nominee to revoke your earlier vote and revote.

Although a revocation is effective if delivered to the Company, we request that either the original or a copy of any revocation be sent to the Discovery Group, c/o The Altman Group, 1200 Wall Street West, Lyndhurst, NJ 07071, so that the Discovery Group will be aware of all revocations.

IF YOU PREVIOUSLY SIGNED AND RETURNED A [    ] PROXY CARD TO THE COMPANY, WE URGE YOU TO REVOKE IT BY (1) SIGNING, DATING AND RETUNING THE WHITE PROXY CARD, (2) ATTENDING THE STOCKHOLDER MEETING AND VOTING IN PERSON OR (3) DELIVERING A WRITTEN NOTICE OF REVOCATION TO THE SECRETARY OF THE COMPANY OR THE DISCOVERY GROUP.

WHAT SHOULD I DO IF I RECEIVE A PROXY CARD SOLICITED BY THE COMPANY?

If you submit a proxy to us by signing and returning the enclosed WHITE proxy card, do not sign or return the proxy card solicited by the Company or follow any voting instructions provided by the Company unless you intend to change your vote, because only your latest-dated proxy will be counted.

If you have already sent a proxy card to the Company, you may revoke it and provide your support to the Discovery Group Nominees by signing, dating and returning the enclosed WHITE proxy card.

WHO CAN VOTE?

The Board of Directors has established January 16, 2009 as the record date for the Stockholder Meeting (the “Record Date”).  Only holders of record of Common Stock on the Record Date will be entitled to vote at and attend the Stockholder Meeting.  If you are a stockholder of record on the Record Date, you will retain the voting rights in connection with the Stockholder Meeting even if you sell such shares after the Record Date.  Accordingly, it is important that you vote the shares of Common Stock held by you on the Record Date, or grant a proxy to vote such shares on the WHITE proxy card, even if you sell such shares after such date.

WHAT IS THE REQUIRED QUORUM?

The holders of a majority of the shares of Common Stock entitled to vote at the Stockholder Meeting, present in person or by proxy, constitute a quorum.

WHAT VOTE IS REQUIRED TO ELECT THE DISCOVERY GROUP NOMINEES AND APPROVE THE STOCKHOLDER PROPOSAL?

Based on the Company Proxy Statement, with respect to the election of directors at the Stockholder Meeting:

·                  the [eight] nominees receiving the highest number of affirmative votes at the Stockholder Meeting will be elected to the Board of Directors; and

·                  abstentions and broker non-votes will be counted as “present” when determining whether there is a quorum, but will not be counted toward a nominee’s attainment of a plurality.

16

Based on the Company Proxy Statement, with respect to the approval of the Stockholder Proposal at the Stockholder Meeting:

·                  the affirmative vote of a majority of the shares of Common Stock present at the meeting, in person or by proxy and voting thereon, is required to approve the Stockholder Proposal; and

·                  proxies that are marked “abstain” will be treated as votes and will have the same effect as a vote “against” the Stockholder Proposal.

HOW WILL MY SHARES BE VOTED?

In the election of directors as the Stockholder Meeting, you are entitled to give a nominee as many votes as is equal to the number of shares you own multiplied by the number of directors to be elected, or you may distribute your votes among the nominees as you see fit.  For example, if you own 100 shares as of the Record Date, and if eight directors are to be elected at the Stockholder Meeting, you have 800 votes that you can allocate among the nominees in any manner you choose.

With respect to the approval of the Stockholder Proposal, each share of Common Stock present in person or by proxy at the Stockholder Meeting will be entitled to one vote.

Shares of Common Stock represented by a valid, unrevoked WHITE proxy card will be voted in accordance with the recommendations made in this Proxy Statement unless you otherwise indicate on the proxy card.  We are soliciting the discretionary authority to cumulate votes, and the persons named as proxies on our proxy card will have the authority to cumulate votes at their discretion.  We will use the authority granted to us by our WHITE proxy card to cumulate votes for the Discovery Group Nominees to assure that the maximum number of Discovery Group Nominees are elected to the Board of Directors.

Except as set forth in this Proxy Statement, the Discovery Group is not aware of any other matter to be considered at the Stockholder Meeting.  However, if the Discovery Group learns of any other proposals made at a reasonable time before the Stockholder Meeting, the Discovery Group will either supplement this Proxy Statement and provide an opportunity to stockholders to vote by proxy directly on such matter or will not exercise discretionary authority with respect thereto.  If other proposals are made thereafter (including at the Stockholder Meeting), the persons named as proxies on the WHITE proxy card solicited by the Discovery Group will vote such proxies in their discretion.

THE DISCOVERY GROUP IS ONLY PROPOSING TWO NOMINEES, WHILE [EIGHT] DIRECTORS ARE EXPECTED TO BE ELECTED AT THE STOCKHOLDER MEETING.  IF I VOTE MY SHARES ON THE WHITE PROXY CARD, HOW MANY NOMINEES WILL I BE VOTING FOR?

The Discovery Group is seeking to elect the maximum number of Discovery Group Nominees. The Discovery Group expects to cumulate all of the votes received in favor of the Discovery Group Nominees.  If the two Discovery Group Nominees are elected, the nominees of the Company who receive the greatest number of votes would be elected as the [six] other directors.
