The Board of Directors has established the close of business on April 14, 2005, as the record date for the determination of stockholders entitled to receive notice of and to vote at the annual meeting and any adjournment or postponement thereof.

YOU ARE URGED TO REVIEW CAREFULLY THE ACCOMPANYING PROXY STATEMENT AND TO COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED PROXY CARD AS PROMPTLY AS POSSIBLE WHETHER OR NOT YOU PLAN TO ATTEND THE MEETING.

Your proxy may be revoked by you at any time before it has been voted. You are cordially invited to attend the annual meeting in person if it is convenient for you to do so.

This proxy statement is provided to the stockholders of Allin Corporation (the “Company”) in connection with the solicitation by the Board of Directors of the Company of proxies for use at the Annual Meeting of Stockholders of the Company to be held on Monday, June 13, 2005, at 1:00 p.m., EDT, at the Company’s headquarters at 381 Mansfield Avenue, Suite 400, Pittsburgh, Pennsylvania 15220-2751, and any adjournments or postponements thereof. A form of proxy is enclosed for use at the annual meeting. Proxies properly executed and returned in a timely manner will be voted at the annual meeting in accordance with the directions specified therein. If no direction is indicated, they will be voted for the election of the nominees named herein as directors, for the amendment of the Company’s Certificate of Incorporation to permit the holders of a majority of the outstanding shares of each series of the Company’s preferred stock to waive their rights and preferences with respect thereto and, in connection therewith, the restatement of the Company’s certificate of incorporation, for the ratification of the appointment of Malin, Bergquist & Company, LLP as the Company’s independent public accountants and, on other matters presented for a vote, in accordance with the judgment of the persons acting under the proxies. The persons named as proxies were selected by the Board of Directors and are presently members of executive management of the Company.

The Company’s executive offices are located at 381 Mansfield Avenue, Suite 400, Pittsburgh, Pennsylvania 15220-2751, and its telephone number is (412) 928-8800. Proxy materials are first being mailed to stockholders beginning on or about May 20, 2005.

Only stockholders of record at the close of business on April 14, 2005 are entitled to vote at the annual meeting. The only classes of voting stock of the Company outstanding and entitled to vote at the annual meeting are as follows: its common stock, par value $.01 per share, of which 6,967,339 shares were outstanding as of the close of business on April 14, 2005, and its Series G Convertible Redeemable Preferred Stock, par value $.01 per share (“Series G Preferred Stock”), of which 150 shares were outstanding as of the close of business on April 14, 2005. The holders of Series G Preferred Stock are entitled to vote with the holders of common stock together as a single class on all matters submitted for a vote of the holders of common stock that do not require a separate class vote of the holders of common stock under the Company’s Certificate of Incorporation or applicable law. Each share of common stock issued and outstanding is entitled to one vote on matters properly submitted at the annual meeting. Each share of Series G Preferred Stock issued and outstanding is entitled to 5,295 votes on matters properly submitted at the annual meeting.

The presence, in person or by proxy, of the holders of shares of common stock and Series G Preferred Stock entitled to cast a majority of the votes on the matters to be presented at the annual meeting is necessary to constitute a quorum for the transaction of business at the annual meeting. Abstentions and properly executed broker non-votes are counted for purposes of determining the presence or absence of a quorum. A broker non-vote occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner. Abstentions are counted in tabulating votes cast on proposals presented to stockholders, whereas broker non-votes are not. Votes cast in person or by proxy at the annual meeting will be tabulated by the election inspector appointed for the meeting.

Directors will be elected by a plurality of the votes of the shares present or represented by proxy at the annual meeting and entitled to vote on the election of directors. That is, the six nominees receiving the greatest number of votes will be elected. If a quorum is present, abstentions and broker non-votes will have no effect on the voting for the election of directors.

The amendment and restatement of the Company’s Certificate of Incorporation requires the approval of a majority of the votes eligible to be cast at the annual meeting. If a quorum is present, broker non-votes and abstentions will have the effect of a negative vote on the proposal to amend and restate the Company’s Certificate of Incorporation. Each series of the Company’s outstanding preferred stock is also entitled to vote, as a separate class, on the amendment and restatement of the Company’s Certificate of Incorporation. The holders of a majority of the outstanding shares of each of the Series C Redeemable Preferred Stock, Series D Convertible Redeemable Preferred Stock, Series F Convertible Redeemable Preferred Stock and Series G Convertible Redeemable Preferred Stock have consented in writing to the proposed amendment and restatement of the Company’s Certificate of Incorporation.

Approval of the ratification of the appointment of independent public accountants for 2005 requires the affirmative vote of a majority of the votes cast in person or by proxy at the annual meeting. If a quorum is present, broker non-votes will have no effect on the voting for the ratification of the appointment of independent public accountants, but abstentions will have the effect of a negative vote.

Stockholders of record voting by proxy may revoke that proxy at any time before it is voted at the annual meeting by delivering written notice to the Secretary of the Company before the vote is taken at the annual meeting, by delivering a proxy bearing a later date before the vote is taken at the annual meeting or by attending the annual meeting in person and casting a ballot contrary to the previously granted proxy. Stockholders whose shares are held in “street name” by a broker and who have instructed the broker to vote the shares must follow the directions received from the broker as to how to change their vote. Stockholders whose shares are held in “street name” by a broker and who wish to vote in person at the annual meeting must first obtain a legal proxy from their broker.

The Board of Directors recommends voting FOR the election of all nominees named herein to the Board of Directors or for a substitute nominee if any of the nominees named herein becomes unable or unwilling to serve, FOR the proposal to amend and restate the Company’s Certificate of Incorporation and FOR the proposal to ratify the appointment of Malin, Bergquist & Company, LLP as the Company’s independent public accountants for 2005. Proxies properly executed and returned in a timely manner will be voted at the annual meeting in accordance with the directions specified therein. If no direction is indicated, they will be voted FOR the election of the director nominees named herein, FOR the proposal to amend and restate the Company’s Certificate of Incorporation, FOR the proposal to ratify the appointment of Malin, Bergquist & Company, LLP as the Company’s independent public accountants for 2005 and, on other matters presented for a vote, in accordance with the judgment of the person acting under the proxy.

The Board of Directors of the Company currently consists of six members, five of whom are independent non-employee directors. The Chairman, Chief Executive Officer and President of the Company is a member of the Board. All directors are elected for a one-year term and hold office until the next annual meeting of stockholders following election and until their successors are duly elected and qualified. All executive officers serve at the discretion of the Board and are elected by the Board each year.

There are no family relationships among the Company’s directors and executive officers. All directors hold office until the next annual meeting of stockholders and until their successors have been elected and qualified. Officers serve at the discretion of the Board of Directors.

If you do not wish your shares to be voted for particular nominees, you may so indicate on the proxy. If, for any reason, any of the nominees shall become unavailable for election, the individuals named in the enclosed proxy may exercise their discretion to vote for any substitutes proposed by the Board of Directors, unless the Board of Directors should decide to reduce the number of directors to be elected at the annual meeting. At this time, the Board of Directors knows of no reason why any nominee might be unavailable to serve.

The business affairs of the Company are managed under the direction of the Board of Directors. During 2004, the Company’s Board of Directors held four meetings and took action by unanimous written consent in lieu of meetings ten times. In 2004, no incumbent director attended fewer than 75% of the total number of Board meetings and meetings of committees upon which he served during the period for which he served as a director.

The Board of Directors has established two committees, the Audit Committee and the Compensation Committee. The Board has no standing nominating committee.

The Audit Committee, established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), has sole authority to appoint or replace the Company’s independent auditor. The Audit Committee is directly responsible for the compensation and oversight of work of the independent auditor, including resolution of disagreements between management and the independent auditor regarding financial reporting, for the purpose of preparing or issuing an audit report or related work. The independent auditor reports directly to the Audit Committee. The Audit Committee has adopted a written charter which was amended as of February 5, 2004 and was filed as an exhibit to the Company’s proxy statement for its 2004 Annual Meeting of Stockholders. The Audit Committee is currently composed of two independent non-employee directors, James S. Kelly and Brian K. Blair. The Audit Committee met independently five times during 2004.

The Compensation Committee reviews and makes recommendations to the Board of Directors concerning the compensation and benefit policies and practices of the Company. The Compensation Committee is currently composed of two independent non-employee directors, Anthony L. Bucci and William C. Kavan. The Compensation Committee met and conferred with the other independent non-employee directors four times during 2004.

The Company has no standing nominating committee or written policies, procedures or charter governing the nomination of director candidates except as set forth in the Company’s Bylaws and as discussed below. The Board of Directors believes that it does not need a separate nominating committee because the full Board is relatively small, has experienced limited turnover and has the time to perform the functions of selecting Board

nominees. Each member of the Board of Directors participates in the consideration of director nominees. The Board of Directors consists of six members all of whom are “independent” as defined under applicable rules of the Securities and Exchange Commission (the “SEC”) and Nasdaq rules, except for Mr. Talarico who also serves as the Company’s Chief Executive Officer and President.

The Board of Directors identifies nominees for director by seeking suggestions as to potential candidates from the current directors. The Chairman of the Board presents any candidate suggested by a director or a stockholder for formal consideration and evaluation by the Board. The Board of Directors evaluates each nominee on a case-by-case basis and takes into account all factors it considers appropriate, including the independence, experience and judgment of the nominee. The Board of Directors believes the members of the Board should have the following attributes: business judgment, management experience, accounting and financial acumen, industry and technology knowledge, leadership ability, strategic vision and willingness to devote sufficient time to attend meetings and participate effectively on the Board of Directors.

The Board of Directors will consider stockholders’ recommendations for nominees for election to the Board of Directors. Generally such nominations must be submitted in writing to the Secretary of the Company at the Company’s principal offices located 381 Mansfield Avenue, Suite 400, Pittsburgh, Pennsylvania 15220-2751 at least 90 days before the anniversary date of the immediately preceding annual meeting. For the 2006 Annual Meeting of the Stockholders, this means that a stockholder would have to submit his or her recommendation for nominees by March 17, 2006. The notice must provide information as required by the Company’s Bylaws, including but not limited to, a brief biographical sketch of the nominee, evidence of the nominee’s willingness to serve if elected, and evidence of the nominating person’s ownership of common stock of the Company. A copy of the Company’s Bylaw requirements will be provided upon request in writing to the Secretary at the principal offices of the Company. The deadline for submitting stockholder recommendations for nominees does not affect the deadline for submitting stockholder proposals for inclusion in the proxy statement, nor does it apply to questions a stockholder may wish to ask at the meeting.

To date, the Company has not engaged any professional consultants or search firm to assist in the process of identifying and evaluating potential nominees for the position of director of the Company. Accordingly, no fees have been paid to any consultants or search firms in the past year.

The Company does not have a formal policy by which stockholders may communicate directly with directors. The Audit Committee of the Board of Directors has considered, but has taken no action with respect to, the adoption of a formal “whistleblower” policy to establish procedures for the receipt, retention and treatment of complaints regarding accounting, internal accounting controls, or auditing matters and the confidential, anonymous submission by employees of concerns regarding questionable accounting or auditing matters. If the Audit Committee adopts such a policy in the future, the Board of Directors expects that all stockholders of the Company will be able to use the same procedures set forth in such a policy to communicate directly with the directors serving on the Audit Committee.

Until such time as the Board of Directors adopts a formal policy, any stockholder who wishes to send communications to the Board of Directors should deliver communications clearly identified as such to the attention of the Secretary of the Company at the principal executive offices of the Company located 381 Mansfield Avenue, Suite 400, Pittsburgh, Pennsylvania 15220-2751. Currently, the Secretary does not screen this correspondence to determine which communications will be relayed to the Board members, but a majority of the independent directors may change this policy if they believe a change is necessary due to the nature and/or volume of the correspondence.

It is the Company’s expectation that all members of the Board of Directors attend the Annual Meeting of Stockholders. All members of the Company’s Board of Directors were present at the Company’s 2004 Annual Meeting of Stockholders.

The Audit Committee is currently composed of two non-employee directors, James S. Kelly (Chairman) and Brian K. Blair. The Board of Directors has determined that each of Messrs. Kelly and Blair is “independent” as set forth in Nasdaq Marketplace Rule 4200(a)(15) and applicable rules of the SEC. In addition, the Board of Directors has determined that Mr. Kelly is an “audit committee financial expert,” as defined by SEC and Nasdaq rules. Because Mr. Kelly owned 22.4% of the outstanding common stock of the Company at the time of the Board’s independence determination, he did not fall within the safe harbor position set forth under Rule 10A-3(e)(1)(ii)(A) promulgated by the SEC under the Exchange Act. This safe harbor position provides that a person holding 10% or less of a class of voting equity securities of an issuer will not be deemed to be an affiliate of such issuer but does not create a presumption that a person exceeding such ownership percentage is an affiliate. Under SEC rules, an audit committee member who is an affiliate of the issuer (other than through service as a director) cannot be deemed to be independent.

The Audit Committee of the Board of Directors assists the Board in fulfilling its responsibility for oversight of the quality and integrity of the accounting, auditing and financial reporting practices of the Company. In discharging its oversight responsibility as to the audit process, the Audit Committee obtained from the independent auditors a formal written statement describing all relationships between the auditors and the Company that might bear on the auditors’ independence consistent with Independence Standards Board Standard No. 1, “Independence Discussions with Audit Committees.” The Audit Committee discussed with Malin, Bergquist & Company, LLP, the Company’s auditors for the fiscal year ended December 31, 2004, any relationships that may impact their objectivity and independence and satisfied itself as to the auditors’ independence. The Audit Committee also discussed with management and the independent auditors the quality and adequacy of the Company’s internal controls. The Audit Committee reviewed with the independent auditors their audit plans, audit scope and identification of audit risks. The Audit Committee also pre-approved all audit, audit-related and permitted non-audit services provided by Malin, Bergquist & Company, LLP to the Company and the related fees for such services, and concluded that such services are compatible with the auditors’ independence. Such non-audit services were limited to tax compliance services during 2004.

The Audit Committee discussed and reviewed with the independent auditors all communications required by generally accepted auditing standards, including those described in Statement on Auditing Standards No. 61, as amended, “Communications with Audit Committees,” and discussed and reviewed the results of the independent auditors’ examination of the financial statements.

The Audit Committee reviewed and discussed the audited financial statements of the Company as of and for the fiscal year ended December 31, 2004 with management and the independent auditors. Management has primary responsibility for the preparation of the Company’s financial statements, and the independent auditors are responsible for expressing an opinion on the conformity of the Company’s audited financial statements with generally accepted accounting principles.

Based on the above-mentioned review and discussions with management and the independent auditors, the Audit Committee recommended to the Board of Directors that the Company’s audited financial statements be included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2004, for filing with the SEC. The Audit Committee has also selected Malin, Bergquist & Company, LLP as the independent auditors for the Company and its subsidiaries for the fiscal year ending December 31, 2005. The Board of Directors has concurred in that selection and has presented the matter to the stockholders of the Company for ratification.

Information concerning Mr. Talarico, the Company’s Chairman, Chief Executive Officer and President, is included above in the biographic summaries of the nominees for director. Information with regard to the remaining executive officer of the Company who is not also a director follows:

Dean C. Praskach, age 47, has held the positions of Chief Financial Officer of the Company since May 1999, Secretary of the Company since March 1998 and Treasurer and Vice President-Finance of the Company since July 1997. Mr. Praskach is the Company’s principal financial and accounting officer. Mr. Praskach also served the Company as Director of Financial Planning from November 1996 to July 1997. Mr. Praskach has held the positions of Vice President-Finance and Treasurer of all of the Company’s subsidiaries since July 1997 or upon acquisition, if later, and was named Secretary of all of the Company’s subsidiaries in March 1998 or upon acquisition, if later. Mr. Praskach has served as a director of Allin Holdings, Inc., a subsidiary of the Company, since 1997. Mr. Praskach served both the Company and THG in a consulting capacity from February 1995 until joining the Company. From September 1989 through July 1994, he was employed at First Westinghouse Capital Corporation in various positions, where he was involved in equity and mezzanine financing of leveraged acquisitions.

The following table sets forth information concerning 2002, 2003 and 2004 compensation of the Chief Executive Officer and President and the other executive officer of the Company (collectively the “Named Executives”).

In February 2002, the Company entered into an amendment to an employment agreement with Mr. Talarico, which was effective as of January 1, 2001 and was subsequently amended in February 2004 such that the term of the agreement was extended through December 31, 2006. The employment agreement was further amended in December 2004. The annual salary as set forth in the employment agreement is $175,000, subject to permitted annual merit increases.

During the term of the employment agreement, Mr. Talarico is eligible to earn annual bonuses awarded at the discretion of the Compensation Committee and approved by the Board of Directors. The payment of any such annual bonus will be contingent upon the achievement of certain corporate and/or personal performance goals as determined by the Compensation Committee. The performance goals are approved by the Board of Directors and

are designed to enhance stockholder value. To be eligible for a bonus for a particular year, Mr. Talarico must be employed by the Company on the last day of the calendar year for which the bonus is earned unless cessation of employment is due to death, disability (as defined in the agreement) or a change in control of the Company, or unless Mr. Talarico attained the performance goals for that year prior to year end. In the event of death or disability, a pro-rated portion of any bonus due will be awarded based on the performance of the Company annualized as of the date of cessation of employment. In December 2004, the Company and Mr. Talarico entered into an amendment to the employment agreement which deleted a provision of the agreement which would have entitled Mr. Talarico to a bonus in the event of a change in control of the Company, as defined in the employment agreement. The Board of Directors awarded a discretionary bonus of $20,000 to Mr. Talarico in respect of 2004 based on Company accomplishments in 2004. The bonus awarded for 2004 was paid in March 2005.

The employment agreement contains restrictive covenants prohibiting Mr. Talarico from competing with the Company or soliciting the Company’s employees or customers for another business during the term of the agreement and for a period of two years after termination or the end of the employment term.

The employment agreement provides that Mr. Talarico will be eligible to participate in the Company’s various stock plans. The employment agreement with Mr. Talarico does not, however, specify any minimum number of options to be awarded during the term of the agreement. Options granted to Mr. Talarico prior to February 13, 2001 vested on May 15, 2001. No options were awarded to Mr. Talarico in 2004 or subsequently.

The employment agreement provides that should Mr. Talarico’s employment by the Company be terminated without cause or in conjunction with or within one year after the occurrence of a change in control of the Company, Mr. Talarico will receive semi-monthly severance payments equal to the semi-monthly base salary payment which he was receiving immediately prior to such termination until the first anniversary of the date of termination. A change in control is defined in the employment agreement as a sale of all or substantially all of the Company’s assets, a merger in which the Company is not the surviving corporation or when a person or group, other than the stockholders of the Company as of January 1, 2001, owns or controls 40% or more of the outstanding common stock. In the event of termination of employment, whether voluntary or involuntary, in conjunction with or within one year after the occurrence of a change in control of the Company, Mr. Talarico will also have the right to convert each of his 260,000 vested options to purchase the Company’s stock granted prior to February 13, 2001 into the right to receive cash in an amount equal to the difference between the fair market value of the stock on the date the right is exercised and the exercise price of the option from which the right was converted. The rights may be exercised at any time prior to the final expiration date of Mr. Talarico’s options, notwithstanding the expiration of the options based on Mr. Talarico’s termination prior to such expiration date. In addition, Mr. Talarico’s options granted prior to February 13, 2001 will automatically convert into such rights immediately prior to the day such options would otherwise terminate based on termination of Mr. Talarico’s employment without cause or in connection with a change of control of the Company.

In June 2000, the Company entered into an employment agreement with Mr. Praskach, which was subsequently amended in February 2001 and December 2004. The term of the employment agreement commenced June 23, 2000 and pursuant to the terms of the 2004 amendment, will continue through June 23, 2010. Mr. Praskach’s current annual salary is $145,000. The employment agreement permits annual merit increases to salary. Mr. Praskach is also eligible to receive a discretionary bonus for any annual period subject to approval by the Board of Directors. A discretionary bonus of $10,000 in respect of 2004 was awarded to Mr. Praskach and was paid in March 2005.

The employment agreement contains restrictive covenants prohibiting Mr. Praskach from competing with the Company or soliciting the Company’s employees or customers for another business during the term of the agreement and for a period of eighteen months after termination or the end of the employment term.

Mr. Praskach is eligible to receive stock options as may be awarded from time to time and under terms similar to options awarded to other employees under the Company’s stock plans. The employment agreement

with Mr. Praskach does not, however, specify any minimum number of options to be awarded during the term of the agreement. No options were awarded to Mr. Praskach in 2004 or subsequently. Options granted to date to Mr. Praskach will vest, except as noted below, at a rate of 20% of each award on each of the first five anniversary dates of any award. Pursuant to the February 2001 amendment to the employment agreement, options to acquire shares of common stock granted to Mr. Praskach under the Company’s stock plans prior to February 13, 2001 will, if not already vested, vest on the date of a change of control of the Company, defined as a sale of all or substantially all of the Company’s assets, a merger in which the Company is not the surviving corporation or when a person or group, other than the stockholders of the Company as of January 1, 2001, owns or controls 40% or more of the outstanding common stock.

The employment agreement also provides that Mr. Praskach will be entitled to receive for up to one year following termination of employment by the Company without cause, semi-monthly severance payments equal to the semi-monthly base salary payment which he was receiving immediately prior to such termination until the earlier of the first anniversary of the termination or the date on which Mr. Praskach obtains other full-time employment. In the event of termination of employment, whether voluntary or involuntary, in conjunction with or within one year after the occurrence of a change of control of the Company, Mr. Praskach will also have the right to convert each of his vested options to purchase the Company’s stock granted prior to February 13, 2001 into the right to receive cash in an amount equal to the difference between the fair market value of the stock on the date the right is exercised and the exercise price of the option from which the right was converted. The rights may be exercised at any time prior to the final expiration date of Mr. Praskach’s options, notwithstanding the expiration of the options based on Mr. Praskach’s termination prior to such expiration date. In addition, Mr. Praskach’s options granted prior to February 13, 2001 will automatically convert into such rights immediately prior to the day such options would otherwise terminate based on termination of Mr. Praskach’s employment in connection with a change of control of the Company. The December 2004 amendment to the employment agreement deleted a provision of the agreement which would have entitled Mr. Praskach to a bonus in the event of a change of control of the Company.

The Company is currently reviewing the employment agreements with Messrs. Talarico and Praskach to determine whether amendments may be required to ensure compliance with new federal legislation under The American Jobs Creation Act, which was enacted in October 2004. This legislation includes major changes in the federal tax laws applicable to nonqualified deferred compensation plans that may impact several of the Company’s executive compensation plans. The Internal Revenue Service is expected to issue regulatory guidance on this legislation shortly.

In October 1996, the Board of Directors adopted the 1996 Stock Plan, and in April 1997, the Board of Directors adopted the 1997 Stock Plan, which was approved by the Company’s stockholders in May 1997. The Board of Directors subsequently approved reissuance of forfeited or expired option grants and restricted shares under the 1996 and 1997 Plans. In September 1998, the Board of Directors adopted the 1998 Stock Plan, which was approved by the Company’s stockholders in December 1998. The Board of Directors subsequently approved reissuance of forfeited or expired option grants and restricted shares under the 1998 Stock Plan, if any. In February 2000, the Board of Directors adopted the 2000 Stock Plan, which was approved by the Company’s stockholders in May 2000. The Board of Directors subsequently approved reissuance of forfeited or expired option grants and restricted shares under the 2000 Stock Plan, if any. All of the Plans provide for awards of stock options, stock appreciation rights, restricted shares and restricted units to officers and other employees of the Company and its subsidiaries and to consultants and advisors (including non-employee directors) of the Company and its subsidiaries. The Plans are administered by the Board of Directors which has broad discretion to determine the individuals entitled to participate in the Plans and to prescribe conditions for eligibility such as the completion of a period of employment with the Company following an award. The Compensation Committee is responsible for making recommendations to the Board of Directors concerning executive compensation, including the award of stock options.

The number of shares originally designated for award under the Company’s 1996, 1997, 1998 and 2000 Stock Plans are 266,000, 300,000, 375,000 and 295,000, respectively. As of December 31, 2004, 18,501 shares of the Company’s common stock, which were originally issued as restricted shares under the 1996 Stock Plan, and 195,722, 237,406, 362,800 and 191,000 options to purchase common shares under the 1996, 1997, 1998 and 2000 Stock Plans, respectively, were outstanding. In December 2004, the Company reserved a total of 39,444 and 11,112 shares under the 1996 and 1997 Stock Plans, respectively, for future contingent grants of stock options to certain employees associated with the management of Allin Consulting of Pennsylvania, Inc.’s operations, if certain financial objectives are realized from Allin Consulting of Pennsylvania, Inc.’s 2005 operations. As of December 31, 2004, 12,333, 51,482, 12,200 and 104,000 shares remained available for future grants under the 1996, 1997, 1998 and 2000 Stock Plans, respectively.

During 2004, there were no grants of stock options or stock appreciation rights to the Named Executives.

The following table and its notes provide information concerning stock options and related stock appreciation rights held by the Named Executives at December 31, 2004. No options or related stock appreciation rights were exercised in 2004.

(2) Messrs. Talarico and Praskach were granted certain stock appreciation rights related to the options included in the table in footnote (1) above. The stock appreciation rights will only become effective upon conversion of the options. There is uncertainty as to whether the events that could result in conversion of the Named Executives’ options into stock appreciation rights, as described under Employment Agreements above, will occur at all or when they may occur. Accordingly, none of the stock appreciation rights were exercisable as of December 31, 2004. Due to these factors, no present values can be determined for stock appreciation rights separate from those estimated for the associated options. Since the exercise prices of the stock appreciation rights are identical to the exercise prices of the associated options, none of the stock appreciation rights were in-the-money at December 31, 2004.

Report of the Compensation Committee of the Board of Directors on Executive Compensation

The Compensation Committee is responsible for making recommendations to the Board of Directors concerning executive compensation, including base salaries, bonuses and awards of stock options and other forms of incentive compensation. Anthony L. Bucci and William C. Kavan are currently members of the Compensation Committee. The Compensation Committee met and conferred with the other non-employee directors four times during 2004.

The Company’s compensation policies are intended to attract and retain people necessary to grow the business on a long-term basis, to encourage the creation and appreciation of stockholder value by providing incentives to employees to act as stockholders accountable for their own actions and the overall success of the Company, to link compensation levels to business results and to maintain an appropriate balance between base salary and short-and long-term compensation.

In determining the compensation of the Company’s Chief Executive Officer and President and its other executive officer, factors taken into account include the Company’s performance under business conditions prevailing in the Company’s lines of business, contributions made by, or expected to be made by, the specific executive officer, the business area for which such person is responsible and the compensation for other executives having similar background and experience.

The basic elements of each executive officer’s 2004 compensation were salary and incentive compensation in the form of a cash bonus. The Compensation Committee may award discretionary annual bonus payments, which the Compensation Committee believes should be tied to both short-and long-term performance of the Company as well as financial performance for stockholders. The Compensation Committee believes that the current level of salary compensation for the Company’s executive officers is fair compared to companies of a similar size with publicly-traded stock that are in similar markets. The Compensation Committee recommended and oversaw the payment of cash bonuses to the senior executives of the Company based on the Company’s 2004 operating performance. Factors taken into consideration included operating results in the face of a reduced number of ship builds by its Interactive Media clients, the creation and growth of the Company’s Business Process Practice Area and the completion of acquisitions to expand this unit with the use of a limited amount of the Company’s liquid and capital resources.

It remains the Committee’s intention to continue to utilize forms of compensation for the Company’s executive officers that favor long-term incentives so that such executives may benefit from any increase in the total enterprise value of the organization.

Mr. Talarico became Chief Executive Officer of the Company at the time of its formation in July 1996 and was appointed President of the Company in May 2002. Mr. Talarico and the Company entered into an amendment to his employment agreement in February 2004, which was made effective as of January 1, 2004, under which the terms of the expiring agreement were extended until December 31, 2006. Under the terms of the employment agreement as amended, Mr. Talarico is entitled to a base salary of $175,000 during 2005 and is entitled to receive annual merit increases. Mr. Talarico’s base salary was $175,000 during the full year 2004. Mr. Talarico received a cash bonus payment of $20,000 in March 2005, which was recorded by the Company during 2004. Mr. Talarico and the Company entered into a further amendment to his employment agreement in December of 2004, under which Mr. Talarico voluntarily relinquished the right to a bonus in the amount of $225,000 to be paid upon a change of control of the Company, as defined in his employment agreement.

All employees of the Company and its subsidiaries, in addition to the Company’s executive officers, are eligible to participate in the Company’s 1996 Stock Plan, 1997 Stock Plan, 1998 Stock Plan and 2000 Stock Plan. As of March 31, 2005, 27 employees of the Company and its subsidiaries were participants under these plans.

At the commencement of each year of service, each non-employee director is entitled to receive an option to acquire 5,000 shares of common stock at an exercise price equal to the closing price of the common stock on the date of the grant. The option grant will vest on the first anniversary of the date of the grant if the individual is serving as a director on that date. On February 5, 2004, Mr. Blair received a grant to acquire 5,000 shares of common stock at the exercise price of $0.44 per share. On August 19, 2004, Messrs. Bucci and Kelly each received a grant to acquire 5,000 shares of common stock at the exercise price of $0.155 per share. On November 8, 2004, Mr. Kavan received a grant to acquire 5,000 shares of common stock at the exercise price of $0.26 per share. On November 12, 2004, Mr. Vickers received a grant to acquire 5,000 shares of common stock at the exercise price of $0.26 per share. On February 24, 2005, Mr. Blair received a grant to acquire 5,000 shares of common stock at the exercise price of $0.245 per share.

Non-employee directors of the Company receive $2,500 for each Board of Directors meeting attended and $500 for each separate committee meeting attended on a date on which no full board meeting is held. Directors of the Company who are also employees do not receive additional compensation for attendance at Board and committee meetings. All directors are reimbursed for out-of-pocket expenses in connection with attendance at Board and committee meetings.

The Compensation Committee consists of two non-employee directors, William C. Kavan and Anthony L. Bucci.

Throughout 2004, the Company had an outstanding note payable, with interest fixed at 7% per annum, in the principal amount of $1,000,000 related to the Company’s 1996 acquisition of Allin Corporation of California (“Allin Consulting-California”). Various interests in the note are held by beneficial holders of greater than five percent of the Company’s common stock, directors and executive officers and entities related to these parties. (1) Henry Posner, Jr. a beneficial holder of greater than five percent of the Company’s common stock, (2) Rosetta Capital Partners LP (“Rosetta”), an entity in which Thomas D. Wright, another beneficial holder of greater than five percent of the Company’s common stock, has an ownership interest, (3) Churchill Group LLC (“Churchill”), an entity in which Mr. Kavan, a non-employee director and beneficial holder of greater than five percent of the Company’s common stock and a member of the Compensation Committee, has an ownership interest, (4) Mr. Talarico, a director, executive officer and beneficial holder of greater than five percent of the Company’s common stock and (5) Mr. Praskach, an executive officer of the Company, respectively, own $675,000, $250,000, $41,667, $16,667 and $16,667 portions of the note payable. Interest expense related to this note was approximately $74,000 for the year ended December 31, 2004. On March 14, 2002, Mr. Posner purchased the note and all of the Company’s outstanding Series F Convertible Redeemable Preferred Stock (“Series F Preferred Stock”), and related accrued interest and dividends, from Les D. Kent, the former sole shareholder of Allin Consulting-California, who was then a beneficial holder of greater than five percent of the Company’s common stock. On April 15, 2002, Mr. Posner sold portions of the purchased note and Series F Preferred Stock to the parties related to the Company as described above. Mr. Posner, Rosetta, Churchill, Mr. Talarico and Mr. Praskach own 675, 250, 41.67, 16.67 and 16.67 shares, respectively, of the Company’s Series F Preferred Stock. See “Security Ownership of Certain Beneficial Owners and Managements”

On December 29, 2000, Messrs. Kavan, Talarico, Posner, Wright, and Praskach purchased 10, 10, 113, 10 and 2 shares, respectively, of the Company’s Series G Preferred Stock at a purchase price of $10,000 per share. In conjunction with the purchase of the shares of Series G Preferred Stock, Messrs. Kavan, Talarico, Posner, Wright and Praskach also received warrants to purchase 57,142, 57,142, 645,710, 57,142 and 11,428 shares, respectively, of the Company’s common stock at $1.75 per common share. The warrants to purchase shares of the Company’s common stock expire on December 29, 2005. If the Company does issue any shares of common stock upon conversion of the Series G Preferred Stock or upon exercise of the warrants, the holders of such shares, including Messrs. Kavan, Talarico, Posner, Wright and Praskach, will have certain rights to require the Company to register the shares for resale under the Securities Act of 1933, as amended. See “Security Ownership of Certain Beneficial Owners and Management.” The holders’ demand registration rights expire on December 29, 2005 and their piggy-back registration rights expire on December 29, 2007.

The following table presents certain information as of March 15, 2005 as to the beneficial ownership of the common stock and Series G Preferred Stock of the Company by each person or entity who is known to the Company to beneficially own more than five percent of the outstanding common stock and/or Series G Preferred Stock. Except as indicated, the persons named have sole voting and investment power with respect to all shares shown as being beneficially owned by them. The percentages in the table are rounded to the nearest tenth of a percent.

The following table presents certain information as of March 15, 2005 as to the beneficial ownership of the common stock and Series G Preferred Stock of the Company by (i) each director and Named Executive and (ii) all directors and executive officers as a group. Each Named Executive and certain directors also beneficially own shares of one or more series of non-voting preferred stock of the Company. Information as to such ownership is given in the notes to the table. Except as indicated, the persons named have sole voting and investment power with respect to all shares indicated as being beneficially owned by them. All percentages are rounded to the nearest tenth of a percent.

The Company rents office space for its Pittsburgh operations on a month-to-month basis from Executive Office Associates (“EOA”). Henry Posner, Jr., a beneficial holder of greater than five percent of the Company’s common stock, and two of Mr. Posner’s sons and his spouse each own an indirect equity interest in EOA. The present arrangement has been in effect since a five-year lease for the office space expired January 31, 2002. At the conclusion of the lease, management believed the Company’s Pittsburgh-based operations could effectively utilize a smaller space due to staff reductions in 2001. The Company’s landlord agreed to permit the Company to continue to occupy its present space until such time as the landlord identifies an alternate tenant for the Company’s space. At that time, the Company will likely move to other space within the same building commensurate with its needs, or if such space is not available, space in another building. Aggregate rental payments under the current arrangement were approximately $136,000 for the year ended December 31, 2004. Management believes rental payments under the current arrangement are on terms as favorable to the Company as could have been obtained from an unrelated party and reflect real estate market conditions as of early 2002, when the current arrangement was made. Management believes the new arrangement benefits both parties. The Company has benefited from a rent reduction as compared to rental payments under the long-term lease, while deferring the cost and inconvenience of moving. EOA has deferred the costs associated with buildout of new space for the Company.

During the fiscal year ended December 31, 2004, Allin Network Products, Inc. (“Allin Network”), a subsidiary of the Company, provided technology infrastructure consulting services to Hawthorne. Richard W. Talarico, a director, executive officer and beneficial owner of greater than five percent of the Company’s common stock, is an officer of Hawthorne. Mr. Posner, two of Mr. Posner’s sons, and Thomas D. Wright, a beneficial holder of greater than five percent of the Company’s common stock, are shareholders of Hawthorne. Fees charged Hawthorne for the consulting services were approximately $32,000 for the fiscal year ended December 31, 2004. Allin Network also sold approximately $16,000 of computer hardware and networking equipment to Hawthorne during the fiscal year ended December 31, 2004. The Company believes its consulting fees and product charges are on terms substantially similar to those offered to unrelated parties.

During the fiscal year ended December 31, 2004, Allin Network provided technology infrastructure consulting services and Allin Consulting of Pennsylvania, Inc. provided business process consulting services to Business Records Management, Inc. (“BRM”). Mr. Wright is a shareholder of BRM. Fees charged BRM for the consulting services were approximately $13,000 by Allin Network and $2,000 by Allin Consulting of Pennsylvania, Inc., respectively, for the fiscal year ended December 31, 2004. Allin Consulting of Pennsylvania, Inc. also sold approximately $13,000 of computer software to BRM during the fiscal year ended December 31, 2004. The Company believes its consulting fees and product charges are on terms substantially similar to those offered to unrelated parties.

On April 5, 2005, the Company’s Board of Directors declared the advisability of and approved, subject to the approval of the Company’s stockholders, amending the Company’s Certificate of Incorporation to permit the holders of a majority of the outstanding shares of each series of the Company’s preferred stock to waive the rights and preferences with respect to such series of preferred stock and, in connection therewith, restating the Company’s Certificate of Incorporation. This amendment relates to the Series C, D, F and G Preferred Stock, which are currently the only outstanding series of preferred stock of the Company.

The Company’s Board of Directors believes that it is in the Company’s best interest to approve the amendment and restatement of the Company’s Certificate of Incorporation.

Amendment to Section 4.2(a) of Article IV of the Certificate of Incorporation That Requires Stockholder Approval

The Company’s Certificate of Incorporation presently authorizes the Company to issue 20,000,000 shares of common stock and 100,000 shares of preferred stock, of which 25,000, 2,750, 1,000 and 150 shares have been designated as Series C, D, F and G Preferred Stock, respectively, all of which shares have been issued and are outstanding.

The proposed amendment to permit the holders of a majority of the shares of the Series C, D, F and G Preferred Stock to waive their respective rights and preferences thereunder will require an amendment to Section 4.2(a) of Article IV of the Company’s Certificate of Incorporation. The amendment to Section 4.2(a) of Article IV is the only amendment to the Company’s Certificate of Incorporation being put forth in this proxy statement that requires stockholder approval. The holders of a majority of the outstanding shares of each of the Series C, D, F and G Preferred Stock, each voting as a separate class, have consented in writing to the proposed amendment to, and restatement of, the Company’s Certificate of Incorporation. If approved by the Company’s stockholders at the annual meeting, the amendment of the Company’s Certificate of Incorporation will become effective upon the filing with the Secretary of State of the State of Delaware of the proposed Amended and Restated Certificate of Incorporation. The Company intends to make this filing promptly after approval by its stockholders. If the Company’s stockholders approve the proposed amendment, Section 4.2(a) of Article IV of the Company’s Certificate of Incorporation will be amended to read as follows:

(i) 25,000 shares are designated as Series C Redeemable Preferred Stock and have such terms as described in the Certificate of Voting Powers, Designations, Preferences and Relative Participating, Optional or Other Rights, and the Qualifications, Limitations or Restrictions Thereof, of the Series C Redeemable Preferred Stock filed with the Secretary of State of the State of Delaware on May 25, 1999, which is attached hereto as Exhibit A and is incorporated herein by reference, and as provided in Section 4.2(a)(v) below;

(ii) 2,750 shares are designated as Series D Convertible Redeemable Preferred Stock and have such terms as described in the Certificate of Voting Powers, Designations, Preferences and Relative Participating, Optional or Other Rights, and the Qualifications, Limitations or Restrictions Thereof, of the Series D Convertible Redeemable Preferred Stock filed with the Secretary of State of the State of Delaware on May 25, 1999, which is attached hereto as Exhibit B and is incorporated herein by reference, and as provided in Section 4.2(a)(v) below;

(iii) 1,000 shares are designated as Series F Convertible Redeemable Preferred Stock and have such terms as described in the Certificate of Voting Powers, Designations, Preferences and Relative Participating, Optional or Other Rights, and the Qualifications, Limitations or Restrictions Thereof, of the Series F Convertible Redeemable Preferred Stock filed with the Secretary of State of the State of Delaware on May 28, 1999, which is attached hereto as Exhibit C and is incorporated herein by reference, and as provided in Section 4.2(a)(v) below;

(iv) 150 shares are designated as Series G Convertible Redeemable Preferred Stock and have such terms as described in the Certificate of Voting Powers, Designations, Preferences and Relative Participating, Optional or Other Rights, and the Qualifications, Limitations or Restrictions Thereof, of the Series G

Convertible Redeemable Preferred Stock filed with the Secretary of State of the State of Delaware on December 28, 2000, which is attached hereto as Exhibit D and is incorporated herein by reference, and as provided in Section 4.2(a)(v) below;

(v) Any of the rights or preferences of the holders of the Series C Redeemable Preferred Stock, the Series D Convertible Redeemable Preferred Stock, the Series F Convertible Redeemable Preferred Stock or the Series G Convertible Redeemable Preferred Stock set forth or incorporated by reference herein may be waived by the affirmative vote of the holders of a majority of the shares of the Series C Redeemable Preferred Stock, the Series D Convertible Redeemable Preferred Stock, the Series F Convertible Redeemable Preferred Stock or the Series G Convertible Redeemable Preferred Stock, as applicable.

The remaining shares of Preferred Stock of the Company may be issued from time to time in one or more classes or series thereof, the shares of each class or series thereof to have such voting powers, full or limited, or no voting powers, and such designations, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, as are stated and expressed herein or in the resolution or resolutions providing for the issuance of such class or series, adopted by the Board of Directors as hereinafter provided. All shares of the same class and series of Preferred Stock will be identical, but shares of different classes or series of Preferred Stock need not be identical or rank equally except as provided by law or herein.

Reasons and Effect of the Amendment to Section 4.2(a) of Article IV of the Certificate of Incorporation

Through the proposed amendment to Section 4.2(a) of the Article IV of the Company’s Certificate of Incorporation, the Company is seeking to streamline the process by which the holders of a majority of the shares of the Series C, D, F and G Preferred Stock may waive the applicability of certain of their existing rights and preferences from time to time. The Company believes that the proposed amendment will provide the Company with the flexibility to seek the waiver of certain of the Company’s obligations to the preferred stockholders without also seeking the approval of the holders of common stock and amending and restating the Company’s Certificate of Incorporation.

For instance, the Company could utilize the streamlined waiver process described in the proposed amendment to institute a share buy-back program to repurchase outstanding shares of its common stock or to pay cash dividends on the common stock. Currently, before the Company can repurchase any shares of its common stock or pay cash dividends on such shares, the Company must obtain the consent of a majority of the holders of the Series C Preferred Stock to waive their right to have the Company pay, or set aside a sum sufficient for the payment of, all accrued but unpaid dividends on the Series C Preferred Stock and must seek the approval of the holders of common stock voting together as a class with the holders of the Series G Preferred Stock to amend and restate the Company’s Certificate of Incorporation to reflect such a waiver by the holders of the Series C Preferred Stock. The consent of the holders of Series C Preferred Stock is necessary because there are currently accrued but unpaid dividends with respect to the Series C Preferred Stock.

The Company also could use the streamlined waiver process to obtain the waiver of preferred stockholders for the redemption of one or more series of the Company’s outstanding preferred stock in the event that the Company fails to make all required payments of dividends on any of its senior series of preferred stock. The Company is required to obtain the consent of holders of one or more series of preferred stock for a redemption of Company securities only if the Company is seeking to redeem shares of a junior series of preferred stock, and the Company has failed to pay, or set aside a sum sufficient for the payment of, all accrued but unpaid dividends, if any, on any outstanding senior series of preferred stock. At the present time, with the consent of its lender and subject to compliance with Delaware law, the Company may redeem shares of any of the Series C, D and F Preferred Stock, and after December 29, 2005, shares of the Series G Preferred Stock, without obtaining the consent of the preferred stockholders or the common stockholders because the Company is not in arrears with respect to the payment of dividends on the Series D, F and G Preferred Stock, which are the Company’s three senior series of preferred stock.

The Company has no present plans, arrangements or understandings with respect to any transaction that would require such a waiver by the holders of any series of the Company’s preferred stock, including the redemption of a particular series of preferred stock, share buy-back program or the payment of dividends on any class of the Company’s stock. It is also the Company’s present intent to remain current in its payment of dividends on the Series D, F and G Preferred Stock.

If the stockholders approve the proposal to amend Section 4.2(a) of Article IV of the Company’s Certificate of Incorporation, the Company would have increased flexibility to seek the waiver of the following rights and preferences of the holders of the various series of the Company’s outstanding preferred stock:

unless all dividends on such series of preferred stock for the designated dividend payment date immediately prior to or concurrent with the payment with respect to any such dividend, distribution, redemption, purchase or acquisition as to such Junior Securities has been paid, or declared and a sum sufficient for the payment thereof set aside by the Company separate and apart from its other funds;

If the stockholders do not approve the proposal to amend Section 4.2(a) of Article IV of the Company’s Certificate of Incorporation, the Company may be unable to engage in certain courses of action, including a share buy-back program or the payment of cash dividends on the common stock, or may find it necessary in the future to convene a special meeting or otherwise obtain the vote of stockholders in the event the Company wishes to seek the approval of the holders of a particular series of the outstanding preferred stock to temporarily or permanently suspend or modify certain rights or preferences of the holders of such series of the Company’s outstanding preferred stock.

The proposed amendment to the Company’s Certificate of Incorporation will have no material adverse effect upon the rights of the holders of the Series C, D, F and G Preferred Stock because the consent of the holders of a majority of the outstanding shares of each such series of preferred stock is currently required before the Company’s Certificate of Incorporation or the certificate of designation relating to such series of preferred stock may be changed or the Board of Directors may take any action, so as to affect adversely the rights and preferences of the holders of such series of preferred stock. The holders of a majority of the outstanding shares of each of the Series C, D, F and G Preferred Stock, each voting as a separate class, have consented in writing to the proposed amendment and restatement of the Company’s Certificate of Incorporation. There are no agreements or understandings, oral or written, between the Company and any of the holders of the Company’s outstanding preferred stock with respect to such holders’ prior consent to the proposed amendment and restatement. Nor are there any agreements or understandings, oral or written, between the Company and the preferred stockholders relating to any future transaction that the Company may undertake or future waivers that the Company may seek in the event that the proposed amendment is approved by stockholders.

The proposed amendment to the Company’s Certificate of Incorporation will have no material adverse or dilutive effect upon the rights of any holders of common stock. The proposed amendment will not provide the Company with any new or additional means of authorizing or issuing preferred or common stock. Nor will it provide the Company with any new or additional means to augment the existing rights and privileges of the preferred stockholders or to further subordinate the interests of common stockholders.

In connection with the amendment of Section 4.2(a) of Article IV, the Company will restate its Certificate of Incorporation to incorporate the previously filed certificates of designation relating to the Series C, D, F and G Preferred Stock because such restatement is required by certain rules and regulations promulgated by the SEC.

Elimination of Other Series of Authorized Preferred Stock and Technical Amendments to Certificate of Incorporation That Do Not Require Stockholder Approval

In connection with the proposed amendment and restatement of the Company’s Certificate of Incorporation, the Company intends to take certain other actions in relation to the Certificate of Incorporation.

Regardless of whether the stockholders approve the amendment to, and restatement of, the Company’s Certificate of Incorporation, the Board of Directors has approved, and the Company intends to file, a Certificate of Elimination to eliminate from the Company’s Certificate of Incorporation all references to the Company’s Series A Convertible Redeemable Preferred Stock (“Series A Preferred Stock”), Series B Convertible Redeemable Preferred Stock (“Series B Preferred Stock”) and Series E Convertible Redeemable Preferred Stock

(“Series E Preferred Stock”). Presently, there are 25,000, 2,750 and 1,926 shares of Preferred Stock designated as Series A, B and E Preferred Stock, respectively, but there are no outstanding shares of the Series A, B or E Preferred Stock. The Board of Directors has further determined that the Company will not issue any such shares in the future. Pursuant to Section 245 of the General Corporation Law of the State of Delaware, stockholder approval for the filing of the Certificate of Elimination is not required.

Upon the elimination of the Series A, B and E Preferred Stock, the Company will treat the shares of Preferred Stock previously designated as Series A, B and E Series of Preferred Stock as authorized but unissued preferred stock that may be issued from time to time in one or more series with such designations, preferences, powers and relative participating, optional or other special rights and qualifications, limitations or restrictions thereof, as shall be stated in the resolutions adopted by the Board of Directors providing for the designation and creation of such series of preferred stock. The effect of the filing of the Certificate of Elimination will be to increase the number of shares of authorized, but unissued blank check preferred stock from 41,424 to 71,100.

The Company’s Certificate of Incorporation presently refers to the incorporator of the Company (Article V) and the stock split that occurred in October 1996 (Section 4.1 of Article IV). In addition, the address of the Company’s registered agent as set forth in Article II is no longer correct. The omission of the references to the incorporator in Article V and the stock split in Section 4.1 of Article IV and the correction of the registered agent’s address are not matters that require stockholder approval.

The Audit Committee of the Board of Directors has selected Malin, Bergquist & Company, LLP (“Malin, Bergquist”) as the independent public accountants to examine the financial statements of the Company and its subsidiaries for the year ending December 31, 2005. The Board of Directors has concurred in the Audit Committee’s selection and is presenting the matter to the stockholders of the Company for ratification at the annual meeting of the stockholders. Malin, Bergquist has provided such services for the Company since its engagement on May 29, 2003. Hill, Barth & King LLC (“Hill, Barth & King”) provided such services for the fiscal year ended December, 31 2002, and Arthur Andersen LLP provided such services for prior fiscal years.

A representative of Malin, Bergquist is expected to be present at the annual meeting for the purpose of making a statement, should such person so desire, and to respond to appropriate questions. A representative of Hill, Barth & King is not expected to be present in person or available by telephone at the annual meeting.

Although ratification is not required, the Board of Directors is submitting the appointment of Malin, Bergquist to the Company’s stockholders for ratification as a matter of good corporate practice. Even if the appointment is ratified, the Audit Committee in its discretion may select a different registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

Also, if the stockholders should not ratify the appointment of Malin, Bergquist, the Audit Committee of the Board of Directors will investigate the reasons for rejection by the stockholders and will reconsider the appointment.

On April 2, 2003, Hill, Barth & King notified the Company that it would not be able to serve as the Company’s independent auditors for the fiscal year ending December 31, 2003 because it probably would not register with the Public Company Accounting Oversight Board. Such registration is required for accountants serving as independent auditors for publicly owned companies. Hill, Barth & King, however, indicated that it would continue to, and did, provide review services for the first quarter of 2003. On May 29, 2003, the Company dismissed Hill, Barth & King as its independent auditors after the Company’s Audit Committee approved the appointment of new independent auditors, Malin, Bergquist.

The report of Hill, Barth & King on the Company’s financial statements for the fiscal year ended December 31, 2002 did not contain an adverse opinion or a disclaimer of opinion, nor was such report qualified or modified as to uncertainty, audit scope or accounting principles.

The policy of the Company’s Audit Committee is to pre-approve audit, audit-related, tax and other permissible services to be performed by the Company’s principal accountant. The need for pre-approval of any services to be performed by the principal accountant is considered in setting the agendas for Audit Committee meetings, and review and approval of proposed fees is undertaken at the Audit Committee meetings as needed. If the principal accountant proposes time-based fees for any services, the Audit Committee will set a not-to-exceed limitation for fees, with subsequent pre-approval required for any additional fees. In cases where pre-approval of services is necessary prior to the next scheduled Audit Committee meeting, approval will be determined by communication with Audit Committee members and documented through written consents in lieu of meetings.

The Audit Committee’s pre-approval policy was implemented as of May 6, 2003, as required by applicable regulations. All engagements of the independent accountant to perform audit and non-audit services since that date have been approved by the Audit Committee in accordance with the pre-approval policy. The policy has not been waived in any instance.
