VALUE PARTNERS, LTD. 2200 Ross Avenue Suite 4660 West Dallas, Texas 75201 (214) 999-1900 June , 1998 Dear Fellow Preferred Stockholder: Value Partners, Ltd., ("Value Partners") is the beneficial owner of 714,317, or 19.87%, of the issued and outstanding shares of the 12% Cumulative Exchangeable Redeemable Preferred Stock, $.01 par value per share (the "Preferred Stock") of Telos Corporation (the "Company"). Value Partners is soliciting your support to elect two Class D directors to the Board of Directors of the Company that are independent of, and have not been selected by, management of the Company. The Company has not declared or paid dividends on the Preferred Stock since 1991. The Company's Articles of Amendment and Restatement of its Articles of Incorporation ("Articles") provide that if dividends are in arrears and unpaid for three full semi-annual periods, then the number of directors constituting the Company's Board of Directors shall, without further action, be increased by two directors (designated as "Class D" directors) and the holders of the Preferred Stock (the "Preferred Stockholders") shall have the exclusive right to elect such directors. Notwithstanding the requirements of the Articles, the Company has failed to call, or permit the Preferred Stockholders to call, a special meeting to elect the two Class D directors. Value Partners, through the registered holder of its shares, Cede & Co. ("Cede"), made demand upon the Company to hold such meeting, was sued by the Company in a declaratory judgment proceeding and counter-claimed to enforce the rights of the Preferred Stockholders to obtain a Special Meeting of the Preferred Stockholders (the "Special Meeting") to elect the Class D directors. On April 22, 1998, the U.S. District Court for the Eastern District of Virginia (the "Court"), decided that the Company was required to hold the Special Meeting for the election of the Class D directors and prohibited the Company from interfering with the meeting or the election. As a result of the Court's decision, the Special Meeting of the Preferred Stockholders to elect the two Class D directors will be held at the law offices of McGuire, Woods, Battle & Boothe, LLP, at the Army Navy Building, 1627 I ("Eye") Street, N.W., Washington, D.C. 20006, on Friday, July 31, 1998, at 10:00 a.m. Value Partners has taken a stand for the Preferred Stockholders by obtaining a decision protecting the rights of all Preferred Stockholders. Value Partners is soliciting your vote in order to elect two nominees, Mr. Julio E. Heurtematte, Jr. and Mr. Malcolm M.B.

Letter to Preferred Stockholders Page 2 Sterrett (the "Nominees"), as the two Class D directors on the Company's Board of Directors. In December 1996, Value Partners became concerned that the Company was failing to live up to its obligations to the Preferred Stockholders, as set forth in the Articles. Value Partners believes that the placement of these two Nominees on the Board of Directors will provide to the holders of the Preferred Stock an ability to participate in the actions of the Board and the executive officers of the Company ("Management") and to, at least, have a voice in the affairs and governance of the Company. If elected, the Nominees would seek to -- - ensure that the Company takes all appropriate steps to enable it to comply with its contractual obligations to the holders of the Preferred Stock; - provide quality leadership and consistent focus; - conduct a thorough review of the Company's strategic objectives and current operations; and - ensure that Management is actively working to promote the best interests of the Company's shareholders, both Common and Preferred. These Nominees will provide something that Telos Corporation has needed for a long time -- independent, outside directors who are not involved in the management of the Company and who will work to hold Management more accountable to the preferred owners of the Company, its Preferred Stockholders. We need your help to implement necessary representation of the Preferred Stockholders on Telos Corporation's Board in order to enhance its corporate governance. If you agree with us that the Preferred Stockholders have the right to ensure that there is independent oversight of the Company's Board now, then we urge you to vote FOR the Nominees on the enclosed WHITE proxy card. It is very important that you be represented at the Special Meeting regardless of the number of shares you own or whether you are able to attend the meeting in person. We urge you to mark, sign and date your WHITE proxy card today and return it in the envelope provided, even if you plan to attend the Special Meeting. Please vote the Value Partners WHITE proxy card today. In the event that you receive proxy cards sent to you by Mr. Litsinger, Mr. Calhoun or Dr. Greenblatt (each a "Challenger"), please do not sign or return them. Value Partners believes that its Nominees

Letter to Preferred Stockholders Page 3 have the unique ability to best represent the Preferred Stockholders, as set forth in detail in the attached Proxy Statement. If you voted a Challenger's proxy card, you have every right to change your vote simply by signing, dating and mailing the enclosed WHITE proxy card. This will automatically cancel your earlier vote since only the latest dated proxy card will count at the Special Meeting. We need your support to enable us to provide effective leadership and oversight on behalf of all the Company's Preferred Stockholders. Sincerely, VALUE PARTNERS, LTD.

1998 SPECIAL MEETING OF HOLDERS OF THE 12% CUMULATIVE EXCHANGEABLE REDEEMABLE PREFERRED STOCK OF TELOS CORPORATION 19886 Ashburn Road Ashburn, Virginia 20147 To Be Held on July 31, 1998 ----------------------------- PROXY STATEMENT of VALUE PARTNERS, LTD. ----------------------------- INTRODUCTION This Proxy Statement and the accompanying WHITE proxy card are being furnished in connection with the solicitation of proxies by Value Partners, Ltd., a Texas limited partnership ("Value Partners"), to be used at the 1998 Special Meeting of holders of the 12% Cumulative Exchangeable Redeemable Preferred Stock (the "Preferred Stock") of Telos Corporation, a Maryland corporation ("Telos" or the "Company"), to be held at the Army Navy Building, 1627 I ("Eye") Street, N.W., Washington, D.C. 20006 in the law offices of McGuire, Woods, Battle & Boothe, LLP, on Friday, July 31, 1998 at 10:00 a.m. and at any adjournments or postponements thereof (the "Special Meeting"). This Proxy Statement and the accompanying WHITE proxy card are first being mailed to holders of the Preferred Stock on or about ___________________, 1998. Value Partners owns 19.87% of Telos' outstanding Preferred Stock and is the single largest holder of the Company's Preferred Stock. This Special Meeting is occurring as a result of the Orders of the U.S. District Court for the Eastern District of Virginia (the "Court"), which were issued as a result of Value Partners' efforts. For a description of the Court's Orders dated April 22, 1998 and May 4, 1998 and its Memorandum Opinion dated April 22, 1998, see "Why You Should Vote for Value Partners' Nominees," below. Value Partners is a Texas limited partnership, of which Ewing & Partners is the general partner. Timothy G. Ewing is a general partner and the Managing Partner of Ewing & Partners. The business of Value Partners primarily consists of long-term investment in capital stocks, warrants, bonds, notes, debentures and other securities, although Value Partners will engage in the trading of securities as market conditions warrant. Value Partners has been a holder of the Company's Preferred Stock since June 30, 1994.

Proxy Statement Page 2 Value Partners is soliciting your proxy in support of the election of Mr. Julio E. Heurtematte, Jr. and Mr. Malcolm M.B. Sterrett (the "Nominees") as the Class D directors of Telos. The Class D directors are the two directors who may be elected to the Telos Board of Directors exclusively by the holders of the Preferred Stock at any time the Company has failed, for any reason, to pay dividends on the Preferred Stock for three consecutive semi-annual periods. No dividends have been paid on the Preferred Stock since 1991. Value Partners believes that two outside Class D directors are needed on the Telos Board to provide an independent voice on the current Board of Directors and a review of the actions taken by the executive officers of the Company ("Management"). On November 24, 1997, April 2, 1997 and April 27 and 28, 1998, Value Partners, a member of the Committee, filed with the Securities and Exchange Commission (the "Commission") amendments to its Schedule 13D setting forth its intent to seek Class D representation on the Board of Directors at the Special Meeting to be held on July 31, 1998 pursuant to the Court's orders. Management of Telos has, for years, blocked all initiatives by the Preferred Stockholders to elect their two independent Class D directors. Value Partners believes that the Board of Directors of Telos needs independent directors, who are persons other than current Management, in order to provide effective leadership on behalf of the Company's Preferred Stockholders. WHY YOU SHOULD VOTE FOR VALUE PARTNERS' NOMINEES The Company's Articles of Amendment and Restatement of the Articles of Incorporation (the "Articles") require that if the Company has failed, for any reason, to pay annual dividends of $1.20 per share on the Preferred Stock for three consecutive semi-annual periods, then the number of directors constituting the Board of Directors shall increase by two directors, without further action, and the holders of the Preferred Stock shall have the exclusive right, voting separately as a class, to elect the directors of the Company to fill such newly created "Class D" directorships. As stated in the Company's Annual Report on Form 10-K for the year ended December 31, 1997, and in the Company's Quarterly Report on Form 10-Q for the three months ended March 31, 1998, the Company has not declared or paid dividends on the Preferred Stock since 1991. Accordingly, the plain language of the Articles gives the Preferred Stockholders the right to elect two Class D directors.

Proxy Statement Page 3 Other holders of the Preferred Stock have sought to have the Company recognize this basic right of representation. However, the Company has consistently failed to comply with these requests for Board representation and has used Company funds to fight such requests, even when legal action has been taken by stockholders against the Company to enforce these rights granted to the stockholders by the Company's Articles. Although the Preferred Stockholders have a clear right to elect two Class D directors, Management has used nonsensical and convoluted legal arguments to prevent the election of the Class D directors. Rather than assist the holders of the Preferred Stock in obtaining their proper representation on the Board, Management has consistently denied the Preferred Stockholders their right to Board representation. Management's attitude and actions have failed to recognize that the holders of the Preferred Stock are preferential owners of the equity of the Company who have certain contractual rights under the Company's Articles, including representation on the Board of Directors if dividends are not paid for the requisite period. In December, 1996, Value Partners, the beneficial owner of 19.87% of the Preferred Stock, came to the conclusion that Management's actions were contrary to the Articles and applicable law and that representation for the Preferred Stockholders was necessary and appropriate. In that regard, on December 23, 1996, Value Partners mailed a registered letter (the "December 23 Letter") to the Company which: (i) requested that the Company call a special meeting of the holders of the Preferred Stock to be held on January 31, 1997 to elect the two Class D directors; (ii) if the special meeting was not called as requested by January 23, 1997, Value Partners, as a beneficial holder of more than 10% of the Preferred Stock, called for a special meeting of the holders of the Preferred Stock to be held on Friday, February 28, 1997 at 2:00 p.m. at the offices of Value Partners' special counsel located in Washington, D.C., and requested, among other things, that the Company provide to holders of record of the Preferred Stock 30 days written notice of the special meeting; and (iii) nominated two persons, Mr. Julio E. Heurtematte, Jr. and Mr. Malcolm M.B. Sterrett, to run as candidates for the Class D director positions. By its December 23 Letter, Value Partners also requested that the Company provide it with access to the stock books of the Company relating to the holders of the Preferred Stock, so Value Partners could communicate with other Preferred Stockholders. On January 7, 1997, the General Counsel of the Company, a Mr. William Brownley ("Mr. Brownley"), contacted Value Partner's special counsel regarding the December 23 Letter. Mr. Brownley claimed that the January 31 date did not provide for sufficient time

Proxy Statement Page 4 to hold a special meeting as required under the Company's bylaws and, in any event, that Value Partners had no right to call a special meeting. By letter dated January 10, 1997, Mr. Brownley stated that: (i) the Company would not call a special meeting of the holders of the Preferred Stock; (ii) Value Partners did not make a proper request for a list of holders of the Preferred Stock; and (iii) the Company would not provide Value Partners with a list of such holders. After an additional written request by Value Partners' special counsel on January 17, 1997, the Company continued to refuse to provide a stockholder list to Value Partners. Notwithstanding the fact that the Company had recognized Value Partners as a major stockholder by virtue of its prior Schedule 13D filings, had engaged in discussions with Value Partners' general partner regarding the Company's Board of Directors, had treated Value Partners as if it were the record holder of the shares beneficially owned by Value Partners and never questioned Value Partners' ownership or ability to exercise its rights as a holder of the Preferred Stock, on January 23, 1997, Mr. Brownley transmitted to Value Partners' special counsel a letter stating that the Company "finds that Value Partners does not appear to be a shareholder of Telos Corporation's public preferred stock. Therefore, Telos does not have the obligation nor, indeed, the right, to respond to any of Value Partners' demands, requests or deadlines." On February 3, 1997, Value Partners' special counsel, on behalf of Value Partners, delivered by registered mail to the Company two letters. The first letter was a demand by Cede which is the official "record" holder of the shares of Preferred Stock beneficially owned by Value Partners. (To avoid confusion, unless otherwise indicated, Cede, as the record holder for Value Partners shall be referred to herein as "Value Partners".) That first letter confirmed and renewed Value Partners' prior demands in its December 23 Letter. Value Partners demanded that: (i) the Company call and hold a special meeting of the holders of the Preferred Stock on March 31, 1997, or, if not called by the Company, in accordance with the terms of the Articles, Value Partners designated itself to call such a meeting and called the special meeting to be held on April 4, 1997 at 2:00 p.m. at the offices of Value Partners' special counsel; (ii) Value Partners' nominees be put on the ballot for election as Class D directors; and (iii) the Company provide to Value Partners a stockholder list pursuant to the Maryland General Corporation Law and the Company's Articles. The second letter, from Value Partners, made a demand upon the Company, pursuant to Rule 14a-7 promulgated under Securities Exchange Act of 1934, for a list of the holders of the Preferred Stock. The Company did not respond to the requests by Cede or Value Partners.

Proxy Statement Page 5 However, on February 26, 1997, the Company filed suit against Cede in the Circuit Court for Loudoun County, Virginia, seeking a declaratory judgment as to: (i) whether the Company was required to enlarge its Board of Directors by two directorships; (ii) whether the holders of the Preferred Stock were entitled to elect two Class D directors; and (iii) whether the Company was obligated to call a special meeting, or alternatively, whether Cede was entitled to call such a meeting. On March 28, 1997, Cede removed the action commenced by the Company to the United States District Court for the Eastern District of Virginia, Alexandria Division. That same day, Cede filed its Answer and Counterclaims (the "Counterclaim") in that litigation. The Counterclaim of Cede demanded, among other things, that the Court: (i) direct the Company to provide Cede with a stockholder list; (ii) declare that (A) the Company's Board of Directors has been increased by two Class D directors, and (B) the holders of the Preferred Stock have the exclusive right under the Company's Articles to elect two Class D directors to fill such directorships either (X) at a special meeting (and Cede is entitled to call that meeting), or (Y) at the Company's annual meeting, if the special meeting would be held during the period within 90 days immediately preceding the date fixed for the Company's annual meeting of stockholders; and (iii) enjoin the Company from interfering with the election of the two Class D directors by the holders of the Preferred Stock either at a special meeting or at the Company's annual meeting. Value Partners agreed to indemnify Cede for the costs of this litigation. Value Partners' litigation counsel represented Cede in this action. On April 22, 1998, the Court granted Cede's motion for summary judgment and ordered the parties to meet and confer regarding an appropriate form of final order by May 1, 1998 (i) enjoining the Company from interfering with the right of Value Partners (through Cede) to elect two Class D directors to the Company's Board of Directors and (ii) compelling the Company to comply with Maryland law and to provide to Value Partners (through Cede) a list of the Company's Preferred Stockholders. In its Memorandum Opinion, the Court determined that there was no dispute that: (i) the holders of the Preferred Stock were entitled to receive cumulative semi-annual 12% dividends on the Preferred Stock, and (ii) if the dividends "payable" on the Preferred Stock are unpaid for three consecutive semi-annual periods, then the holders of the Preferred Stock have the right to elect two Class D directors to the Company's Board of Directors. The issue presented in the case was that the Company claimed that the Preferred Stockholders had no right to elect the two Class D directors because the dividends were not "payable" because they were not "legally available for payment" due to various impediments, such as the restrictive covenants in the Company's loan agreements.

Proxy Statement Page 6 The Court determined that the intrinsic evidence, including the (i) plain meaning of the Articles, (ii) the terms and structure of other charter provisions, and (iii) the purpose of the provisions in the Articles, all point conclusively to the conclusion that "payable" means due or owed and that the right to elect the Class D directors was intended by the drafters of the Articles to be triggered by the non-payment of the dividends for three consecutive semi-annual periods "for whatever reason." In its analysis, the Court found the Company's legal arguments to be "nonsense" and that "injunctive relief is warranted to compel Telos to meet its statutory obligations to [Value Partners] to provide a verified stockholder list." The judge's opinion further found that an injunction preventing Telos from interfering with the election was appropriate since Value Partners (through Cede) had: "convincingly demonstrated that (i) it has succeeded on the merits of its claim, (ii) there is no adequate remedy at law, (iii) the balance of the equities favors [Value Partners], and (iv) the public interest is served by the issuance of the injunction." On May 4, 1998, the Court entered an Order which set forth the terms and conditions of the Special Meeting and which stated that: (i) Telos represented to the Court that it would follow and abide by the Court's Order of April 22, 1998; (ii) the dividends payable on the Preferred Stock have been in arrears and unpaid for more than three consecutive full semi-annual periods and the Preferred Stockholders are entitled to elect two Class D directors to the Telos Board; (iii) Cede was entitled to a stockholders list on or before May 8, 1998 (which list has been so delivered); (iv) Cede was awarded final judgment on its Counterclaim; (v) Telos shall take all necessary actions to hold a special meeting of its Preferred Stockholders on or before July 31, 1998 to allow the Preferred Stockholders to elect two Class D directors in accordance with the Telos Articles and Bylaws; and (vi) Telos must send the requisite notice of the Special Meeting to the Preferred Stockholders on or before May 11, 1998. THE COMMITMENT OF THE NOMINEES The Nominees are committed to providing independent, outside representation on the Telos Board on behalf of the Preferred Stockholders and to the commencement of the payment of the accrued dividends on the Preferred Stock, as soon as possible. If elected, the Nominees would seek to -- - provide quality leadership and consistent focus;

Proxy Statement Page 7 - conduct a thorough review of the Company's strategic objectives and current operations; - ensure that the Company take all appropriate steps to enable it to comply with its contractual obligations to the holders of the Preferred Stock; and - ensure that Management is actively working to promote the best interests of the Company's shareholders, both Common and Preferred. Value Partners believes that the Company is at a crossroads. It needs, but currently lacks, the type of leadership and guidance that can only be provided by completely independent members of the Board of Directors. A vote for the Nominees is a vote for directors who are independent of Management and who are committed to providing the proper leadership and oversight which the Company needs. If, like us, you believe that the Board of Directors of Telos needs to have directors who are independent of Management in order to represent the interests of the Preferred Stockholders, Value Partners urges you to mark, sign, date and return the enclosed WHITE proxy card to vote FOR the election of each of the Nominees as soon as possible! ELECTION OF DIRECTORS General The Company's Restated Bylaws provide that the number of directors shall be not less than three (3) nor more than fifteen (15). There are currently four (4) members of the Board of Directors. The Company's Articles provide that if dividends on the Preferred Stock are in arrears and unpaid for three full semi-annual periods, then the number of directors constituting the Company's Board of Directors, without further action, shall be increased by two (Class D) directors and the holders of the Preferred Stock shall have the exclusive right to elect such directors. The Company is subject to a Court order prohibiting it from interfering with the election of the Class D directors. The Class D directors shall serve until the next Annual Meeting of stockholders of the Company and until their successors are elected and qualified. The Class D director positions will terminate and no Class D

Proxy Statement Page 8 directors will be permitted to be elected to the Board of Directors and the number of directors constituting the Board of Directors shall be reduced, without further action, by two at such time as all dividends accumulated on the Preferred Stock shall have been paid in full, subject to reverting in the event of each and every subsequent failure of the Company to pay dividends for three consecutive full semi-annual periods. Compensation of Directors During the fiscal year ended December 31, 1997, employee directors were paid a fee of $2,000 for each Board meeting attended. Outside directors Mr. Norman P. Byers and Dr. Stephen D. Bryen were paid an annual fee of $25,000, and further compensated at a rate of $750 for each meeting in excess of four meetings a year. Chairman of the Board, Dr. Fred Charles Ikle, is paid $25,000 quarterly for his service on the Board. In addition, Mr. Byers receives $5,000 per annum for his service as Proxy Chairman. The compensation paid to the outside directors is paid pursuant to a proxy agreement between the Company, the Defense Security Service and certain of the Company shareholders. During the fiscal year ended December 31, 1997, no directors of the Company were awarded options. The Nominees Value Partners orally requested, through its special counsel in Washington, D.C., that the Nominees serve as the Class D directors. Value Partners is not compensating the Nominees for such service or for agreeing to become nominees. Neither Mr. Heurtematte nor Mr. Sterrett is related by blood, marriage or adoption to any member of the Board of Directors or to any of the executive officers named in the Company's Form 10-K for the year ended December 31, 1997. Value Partners recommends that Preferred Stockholders of Telos elect the Nominees as the Class D Directors of Telos at the Special Meeting. If both Nominees are elected, the Nominees would constitute one-third of the entire Board of Directors of Telos. The Nominees and their business qualifications are listed below. Julio E. Heurtematte, Jr. Mr. Heurtematte, 62, has been a private consultant since 1989, specializing in international projects, trade and investments.

In addition, Ewing Asset Management, L.L.C., a Texas limited liability company, holds a 1% general partnership interest in Ewing & Partners. Mr. Ewing is the Manager and 100% owner of EAM. As such, Mr. Ewing has the authority to cause such entities to acquire, hold, trade and vote the Preferred Stock. None of such entities were formed solely to acquire, hold or sell the Preferred Stock. Each of such entities holds securities issued by one or more companies other than the Company. The limited partners in Value Partners are sophisticated, "accredited" investors and are passive investors who do not, directly or indirectly, participate in the management of these entities. Value Partners is a private investment fund. The voting power over the Preferred Stock is not subject to any contingencies beyond the standard provisions for entities of this nature (i.e., limited partnerships) which govern the replacement of a general partner. None of the limited partners are "participants" in this solicitation. The principal place of business for Ewing & Partners, EAM and Mr. Ewing is the same as for Value Partners; it is 2200 Ross Avenue, Suite 4660, Dallas, Texas 75201. The following table sets forth information with respect to purchases of the Preferred Stock of the Company by Value Partners in the two years preceding the date of this Proxy Statement.

Proxy Statement Page 16 VOTING Preferred Stockholders are urged to mark, sign and date the enclosed WHITE proxy card and return it today in the enclosed postage-paid envelope in time to be voted at the Special Meeting. The record date for determining stockholders entitled to notice of and to vote at the Special Meeting is June 26, 1998 (the "Voting Record Date"). Stockholders of record at the close of business on the Voting Record Date will be entitled to one vote at the Special Meeting for each share of Telos Preferred Stock held on the Voting Record Date and for as many individuals as there are directors to be elected. As of May 15, 1998, based on the Company's Form 10-Q for the quarter ended March 31, 1998, there were 3,595,586 shares of Preferred Stock issued and outstanding. Only holders of record of the Preferred Stock as of the close of business on the Voting Record Date will be entitled to vote. If you were a Preferred Stockholder of record on the Voting Record Date, you may vote your shares at the Special Meeting even if you have since sold your shares. Accordingly, please vote the shares held by you on the Voting Record Date, or grant a proxy to vote such shares, on the WHITE proxy card, even if you sold your shares after the Voting Record Date. If any of your shares are held in the name of a brokerage firm, bank, bank nominee or other institution on the Voting Record Date, only it can vote such shares and only upon receipt of your specific instructions. Accordingly, please contact the person responsible for your account and instruct that person to execute on your behalf the WHITE proxy card. The WHITE proxy solicited hereby, if properly signed and returned to Value Partners and not revoked prior to its use, will be voted in accordance with the instructions contained therein. If no contrary instructions are given, each proxy received will be voted FOR the Nominees for director described herein and, upon the transaction of such other business as may properly come before the meeting, in accordance with the best judgment of the persons appointed as proxies. Any stockholder giving a proxy has the power to revoke it at any time before it is exercised by (i) submitting a duly executed proxy bearing a later date; or (ii) appearing at the Special Meeting and giving the Secretary notice of his or her intention to vote in person. Proxies solicited hereby may be exercised only at the Special Meeting and any adjournment thereof and will not be used for any other meeting. Each share of Preferred Stock is entitled to one vote at the Special Meeting on all matters properly presented at the meeting and may be voted for as many individuals as there are directors to be elected. Directors are elected by a plurality of the votes cast with

Proxy Statement Page 17 a quorum present. A quorum consists of stockholders representing, either in person or by proxy, a majority of the outstanding Preferred Stock entitled to vote at the meeting. Abstentions are considered in determining the presence of a quorum but will not affect the plurality vote required for the election of directors. If the election of the Class D directors is contested, under rules applicable to broker-dealers, the proposal for the election of the Nominees would be considered a "non- discretionary" item upon which broker-dealers may not vote on behalf of their clients unless such clients have furnished voting instructions. As a result, there may be broker non-votes at the Special Meeting. However, broker non-votes will have no effect on the election of directors by a plurality vote. If there is no contest, the proposal for the election of the Nominees would be considered a "discretionary" item upon which broker-dealers may vote on behalf of their clients where the clients have not submitted voting instructions. In that case, there would be no broker non-votes at the Special Meeting. VALUE PARTNERS STRONGLY RECOMMENDS A VOTE FOR THE ELECTION OF THE NOMINEES. OTHER MATTERS Each proxy solicited hereby also confers discretionary authority on the proxies named on the WHITE proxy card to vote the proxy with respect to the election of any person as a director if a Nominee is unable to serve or for good cause will not serve, matters incident to the conduct of the meeting, and upon such other matters as may properly come before the Special Meeting. Value Partners is not aware of any business that may properly come before the Special Meeting other than the matters described above in this Proxy Statement. However, if any other matters should properly come before the meeting, it is intended that the proxies solicited hereby will be voted with respect to those other matters in accordance with the judgment of the persons voting the proxies. Value Partners or the Nominees may solicit proxies by mail, advertisement, telephone, facsimile, telegraph and personal solicitation. Value Partners or its regular employees or the Nominees may solicit proxies personally or by telephone without additional compensation. Value Partners or the Nominees will reimburse banks, brokerage firms and other custodians, nominees and fiduciaries for reasonable expenses incurred by them in sending proxy solicitation materials to the beneficial owners of the Common Stock. Value Partners has retained D.F. King & Co., Inc., 77 Water Street, New York, New York 10005, a professional proxy solicitation firm, to assist in the solicitation of proxies and

Proxy Statement Page 18 for related services. Value Partners will pay D.F. King & Co., Inc. a fee of $4,000 plus $3.00 per telephone call and has agreed to reimburse it for its reasonable out-of-pocket expenses. Value Partners has agreed to indemnify D.F. King & Co., Inc. and its controlling persons, officers, directors, employees and agents from and against any and all losses, claims, damages, liabilities and expenses relating to its engagement, including liabilities and expenses under the federal securities laws, but excluding matters relating to the indemnified person's negligence, bad faith or willful misconduct. Approximately 30 persons will be used by D.F. King & Co., Inc. in its solicitation efforts. Value Partners will initially bear the cost of soliciting proxies in connection with the Special Meeting. The cost of such solicitation, which includes the fees of Value Partners' attorneys, solicitors, advertising, printing and mailing and other costs incidental to the solicitation, including litigation fees and expenses, cannot be stated with precision at this time. However, Value Partners estimates that the total expenditures relating to this proxy solicitation will be approximately $165,000, of which approximately $142,000 has been incurred as of March 31, 1998, which fees and expenses began to accrue on or about May, 1996. Of the total estimate, approximately $100,000 relates to fees and expenses incurred in connection with litigation necessitated by the refusal of the Management to abide by the clear requirements of the Company's Articles and hold a special meeting to elect the Class D directors. If the Nominees are elected to the Board of Directors, Value Partners presently intends to seek reimbursement from the Company for the costs incurred by the Committee, but does not presently intend to submit the question of such reimbursement to a vote of the stockholders. Value Partners assumes no responsibility for the accuracy or completeness of any information contained herein which is based on, or incorporated by reference to, the Company's Form 10-K for the year ended December 31, 1997 or the Form 10-Q for the quarter ended March 31, 1998, or its other public filings.
