       The accompanying proxy is solicited by the Board of Directors (the “Board of Directors”) of Nanophase Technologies Corporation, a Delaware corporation (the “Company”), for use at the Annual Meeting of Stockholders (the “Annual Meeting”) to be held at 9:30 a.m., Chicago time, Monday, July 24, 2006, at Nanophase Technologies Corporation, 1319 Marquette Drive, Romeoville, Illinois, and any adjournments thereof. This Proxy Statement and accompanying form of proxy are first being mailed to stockholders on or about June 19, 2006.
      Record Date and Outstanding Shares — The Board of Directors has fixed the close of business on May 30, 2006, as the record date (the “Record Date”) for the determination of stockholders entitled to notice of, and to vote at, the Annual Meeting or any adjournments thereof. As of the Record Date, the Company had outstanding 18,004,464 shares of Common Stock, par value $.01 per share (the “Common Stock”). Each outstanding share of Common Stock is entitled to one vote on all matters to come before the Annual Meeting.
      Voting of Proxies — Joseph E. Cross and Jess Jankowski, the persons named as proxies on the proxy card accompanying this Proxy Statement, were selected by the Board of Directors to serve in such capacity. Messrs. Cross and Jankowski are executive officers of the Company and Mr. Cross is also a director of the Company. The shares represented by each executed and returned proxy will be voted in accordance with the directions indicated thereon, or, if no direction is indicated, such proxy will be voted in accordance with the recommendations of the Board of Directors contained in this Proxy Statement. Each stockholder giving a proxy has the power to revoke it at any time before the shares it represents are voted. Revocation of a proxy is effective upon receipt by the Secretary of the Company of either (1) an instrument revoking the proxy or (2) a duly executed proxy bearing a later date. Additionally, a stockholder may change or revoke a previously executed proxy by voting in person at the Annual Meeting (attendance at the Annual Meeting will not, by itself, revoke a proxy).
      Required Vote — The vote of a plurality of the shares of Common Stock voted in person or by proxy is required to elect the nominees for Class III director. The affirmative vote of a majority of the outstanding shares of Common Stock is required to approve the amendment to the Company’s Certificate of Incorporation increasing the Company’s authorized Common Stock. The affirmative vote of a majority of the shares of Common Stock represented in person or by proxy is required to approve the amendment to the Company’s 2004 Equity Compensation Plan. Stockholders will not be allowed to cumulate their votes in the election of directors.
      Quorum; Abstentions and Broker Non-Votes — The required quorum for transaction of business at the Annual Meeting will be a majority of the shares of Common Stock issued and outstanding as of the Record Date. Votes cast by proxy or in person at the Annual Meeting will be tabulated by the election inspectors appointed for the meeting and will determine whether or not a quorum is present. Abstentions and broker non-votes will be included in determining the presence of a quorum. Abstentions and broker non-votes will have no effect on the vote for directors. With respect to approving the amendment to the Company’s Certificate of Incorporation, abstentions and broker non-votes will be considered present and entitled to vote and will have the same effect as votes “Against” such proposal. With respect to approving the amendment to the Company’s 2004 Equity Compensation Plan, abstentions will be considered present and entitled to vote and will have the same effect as votes “Against” such proposal, while broker non-votes will not be considered present and entitled to vote and will have no effect on such proposal.

      Director Compensation — Upon first being elected to the Board of Directors, each director of the Company who is not an employee or consultant of the Company (an “Outside Director”) is granted stock options to purchase 10,000 shares of common stock at the fair market value of the common stock, as determined by a committee appointed by the Board of Directors, as of the date of issuance of such stock options. This initial option grant to an Outside Director vests over five years. Prior to 2004, on or after the date of each annual meeting of the stockholders of the Company, each Outside Director who was re-elected or continued to serve as an Outside Director because his or her term had not expired was granted stock options to purchase 2,000 shares of common stock provided that such grant was not made to an Outside Director who was first elected to the Board of Directors within three months prior to such annual meeting. The options granted annually to Outside Directors vest in three equal annual installments beginning on the first anniversary of the date of grant. All options granted to Outside Directors expire ten years from the date of grant.
      Prior to 2004, the Company also paid Outside Directors a combination of restricted common stock and cash so that the total value of the compensation equaled approximately $25,000 per year. In 2005 and 2004, the Company paid $6,250 quarterly, which amounted to an annual total of $25,000 per Outside Director, in cash compensation for services performed in their capacity as directors.

      In 2005, the Company adopted, and the Shareholders’ approved, the Nanophase Technologies Corporation 2005 Non-Employee Director Restricted Stock Plan (the “Director Restricted Stock Plan”) which reserves 150,000 shares of the Company’s common stock to be issued to Outside Directors in the form of restricted shares. In 2005, no awards were made under the Director Restricted Stock Plan. In 2005, the Company also adopted the Nanophase Technologies Corporation Non-Employee Director Deferred Compensation Plan (the “Director Deferred Compensation Plan”) which permits an Outside Director to defer the receipt of director fees until separation from service or the Company undergoes a change in control. The Company amended the Director Restricted Stock Plan in 2005 to permit an Outside Director to defer receipt of restricted stock granted under it. The deferred restricted shares are accounted for under the Director Deferred Compensation Plan and issued upon separation from service or the Company’s change in control. Under the Director Deferred Compensation Plan, the deferred fees that would have been paid in cash are deemed invested in 5 year U.S. Treasury Bonds during the deferral period. The accumulated hypothetical earnings are paid following the Outside Director’s separation from service or the Company’s change in control. The deferred fees that would have been paid as restricted shares are deemed invested in common stock of the Company during the deferral period. The Director Deferred Compensation Plan is an unfunded, nonqualified deferred compensation arrangement. In 2005, no amounts were deferred under the Director Deferred Compensation Plan.
      Meetings of the Board and Committees — During the year ended December 31, 2005, the Board of Directors held thirteen formal meetings. No director missed more than one board and committee meeting held during 2005 (for all committees on which a particular director served).
      Committees of the Board of Directors — The Board of Directors has established an Audit and Finance Committee, Compensation and Governance Committee and a Nominating Committee each comprised entirely of independent directors who are not officers or employees of the Company. The members of the Audit and Finance Committee are Mr. McClung (Chairman), Mr. Pearlman and Mr. Perkins. The members of the Compensation and Governance Committee are Mr. Pearlman (Chairman), Mr. Henderson and Mr. Perkins. The members of the Nominating Committee are Mr. Henderson (Chairman), Mr. McClung, Mr. Pearlman, Mr. Perkins and Dr. Siegel.
      The Audit and Finance Committee generally has responsibility for retaining the Company’s independent public auditors, reviewing the plan and scope of the accountants’ annual audit, reviewing the Company’s internal control functions and financial management policies and reporting to the Board of Directors regarding all of the foregoing. The Audit and Finance Committee held seven formal meetings in 2005. The Board of Directors has determined that Mr. Pearlman and Mr. Perkins, both of whom serve on the Audit and Finance Committee, are “audit committee financial experts” as described in applicable SEC rules. Each member of the Audit and Finance Committee is independent, as defined in Rule 4200(a) (15) of the National Association of Securities Dealers’ listing standards and applicable SEC rules.
      The Compensation and Governance Committee generally has responsibility for recommending to the Board of Directors guidelines and standards relating to the determination of executive and key employee compensation, reviewing the Company’s executive compensation and general corporate governance policies and reporting to the Board of Directors regarding the foregoing. The Compensation and Governance Committee also has responsibility for administering the 2004 Equity Compensation Plan, determining the number of options, if any, to be granted to the Company’s employees and consultants pursuant to the 2004 Equity Compensation Plan and reporting to the Board of Directors regarding the foregoing. The Compensation and Governance Committee held five formal meetings in 2005.
      The Nominating Committee generally has responsibility for nominating candidates to serve on the Board of Directors. All members of the Nominating Committee are independent. The Nominating Committee was formed in 2004 and held one formal meeting in 2005.
      Communications with the Board of Directors — Any stockholder desiring to communicate with the Board of Directors or one or more of its directors may send a letter addressed to the Board of Directors or the applicable directors in care of the Corporate Secretary at Nanophase Technologies Corporation, 1319 Marquette Drive, Romeoville, Illinois 60446.

Communications will be forwarded to the proper recipient unless they (a) concern individual grievances or other interests that could not reasonably be construed to be of concern to the stockholders or other constituencies of the Company, (b) advocate the Company’s engaging in illegal activities, (c) contain offensive, scurrilous or abusive content, or (d) have no rational relevance to the business or operations of the Company.
      Directors’ Attendance at Annual Meetings — When a director is unable to attend an Annual Meeting of Stockholders in person, but is able to attend by electronic conferencing, the Company will arrange for the director to participate by means such that the director can hear and be heard by those present at the meeting.

REPORT OF THE COMPENSATION AND GOVERNANCE COMMITTEE
OF THE BOARD OF DIRECTORS
      The current Compensation and Governance Committee members are Jerry K. Pearlman (Chairman), James A. Henderson and Donald S. Perkins. The Compensation and Governance Committee generally has responsibility for recommending to the Board of Directors guidelines and standards relating to the determination of executive and key employee compensation, reviewing the Company’s executive compensation and general corporate governance policies and reporting to the Board of Directors regarding the foregoing. The Compensation and Governance Committee also has responsibility for administering the 2004 Equity Compensation Plan, determining the number of options, if any, to be granted to the Company’s employees and consultants pursuant to the 2004 Equity Compensation Plan and reporting to the Board of Directors regarding the foregoing. The Compensation and Governance Committee held five formal meetings in 2005.
Base Salaries
      In determining the base salaries of the executive officers in 2005, the Compensation and Governance Committee considered the performance of each executive, the nature of the executive’s responsibilities, the salary levels of executives at comparable high technology companies, including other publicly-held advanced materials and advanced technologies companies and the Company’s general compensation practices.
Cash Bonuses
      Discretionary cash bonuses for executive officers are directly tied to achievement of specified goals of the Company and are a function of the criteria which the Compensation and Governance Committee believes appropriately take into account the specific areas of responsibility of the particular officer.
Equity Compensation
      Periodically, the Compensation and Governance Committee may grant equity compensation, in the form of stock options, restricted share rights, and performance share rights, to executive officers in order to provide a long-term incentive which is directly tied to the performance of the Company’s stock. These grants provide an incentive to maximize stockholder value by providing the Company’s employees an equity interest which further aligns their interests with those of the stockholders. The exercise price of these grants is the fair market of the underlying Common Stock on the date of grant. In general, the options vest in equal annual installments over a three-year period beginning one year after the date of grant, in certain instances the Board of Directors (or the Compensation and Governance Committee) can adjust the vesting period for performance-based options. Restricted share rights typically “cliff vest,” all at one time, at a date several years subsequent to their grant date. Performance restricted share rights vest upon the achievement of milestones as defined by the Compensation and Governance Committee. Vesting periods are used to retain key employees and to emphasize the long-term aspect of contribution and performance. In making such grants to executives in 2005, the Compensation and Governance Committee considered a number of factors, including the performance of such persons, the Company’s performance, achievement of specific delineated goals, the responsibilities and the relative position of such persons within the Company, the compensation of executives in comparable high technology companies and the number of stock options each such person currently possesses.
Chief Executive Officer Compensation
      Joseph Cross has served as the Company’s President since November 1998 and its Chief Executive Officer since December 1998. Under his employment agreement with the Company dated November 9, 1999,

Table of Contents

Mr. Cross was paid a base salary of $320,000 in 2005 and received options to purchase 15,000 shares of common stock which vest over a three-year period and 2,500 shares of restricted and performance share rights respectively. The restricted share rights vest in lump sum or “cliff vest” on September 27, 2008, provided that the grantee has not terminated service prior to the vesting date. The performance share rights also vest in lump sum or “cliff vest” upon achievement of certain performance goals or milestones on or before January 30, 2009, provided that the grantee has not terminated service prior to the vesting date. In determining the level of salary payments and option grants to Mr. Cross, the Compensation and Governance Committee considered qualitative factors such as Mr. Cross’s strong leadership role in coordinating the Company’s development of partnering relationships with key customers, the Company’s transition to a producer and supplier of commercial quantities of nanomaterials, the expansion of the Company’s intellectual property assets, and the development of new strategic initiatives.
Compliance with Section 162(m)
      The Compensation and Governance Committee currently intends for all compensation paid to the Named Officers to be tax deductible to the Company pursuant to Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162(m)”). Section 162(m) provides that compensation paid to the Named Officers in excess of $1,000,000 cannot be deducted by the Company for Federal income tax purposes unless, in general, (1) such compensation is performance-based, established by a committee of outside directors and objective, and (2) the plan or agreement providing for such performance-based compensation has been approved in advance by stockholders. The Compensation and Governance Committee believes that the requirements of Section 162(m) are uncertain at this time and may arbitrarily impact the Company. In the future, the Compensation and Governance Committee may determine to adopt a compensation program that does not satisfy the conditions of Section 162(m) if in its judgment, after considering the additional costs of not satisfying Section 162(m), such program is appropriate.

Compensation and Governance Committee Interlocks and Insider Participation
      Pursuant to a consulting agreement effective as of October 29, 1998, and prior to his appointment as Chairman of the Board of Directors, Donald S. Perkins, who is Chairman of the Compensation and Governance Committee, was engaged by the Company to provide additional services in connection with the Company’s organizational restructuring and refocusing. In consideration for such services, Mr. Perkins was granted options to purchase 25,000 shares of Common Stock at an exercise price of $3.50 per share, of which 20,000 options remain vested but unexercised.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
      In addition to items listed elsewhere in this Proxy Statement, on September 5, 2003, in anticipation of the September 8, 2003 private placement to Grace Brothers Ltd., the Company amended its existing Stockholder Rights Agreement to revise the beneficial ownership threshold at which a person or group of persons becomes an “acquiring person” and triggers certain provisions under the Stockholder Rights Agreement. As revised, a person or group would become an “acquiring person” if that person or group becomes the beneficial owner of 35% or more of the outstanding shares of the Company’s stock. Prior to such amendment, the beneficial ownership threshold was 25%. On September 8, 2003, the Company issued 453,001 shares of its common stock to Grace Brothers Ltd. at a purchase price of $4.415 per share together with a warrant to purchase a like number of shares of common stock during the next twelve months also at a price of $4.415 per share. The share price for the common stock was determined based on the fifteen-day market closing average for the Company’s stock ending September 5, 2003. On September 2, 2004 the warrants were exercised to acquire 453,001 newly issued shares of common stock. Grace Brothers, Ltd. beneficially owns approximately 19.9% of the Company’s outstanding common stock. Ms. R. Janet Whitmore is a sister of Bradford Whitmore who serves as the general partner of Grace Brothers, Ltd.
      On March 23, 2004, the Company entered into a joint development agreement with Altana Chemie, AG (“Altana”) in order to explore new product applications in fields that are mutually beneficial to both companies. Pursuant to the agreement, the Company and Altana have granted each other, subject to limited exceptions, exclusive rights for the development and purchase of nanomaterials for use in paints, coatings, inks, polymers and plastics, varnishes, and similar applications. In connection with this agreement the Company sold, in a private placement to Altana, 1,256,281 shares of common stock at $7.96 per share and received gross proceeds of $10 million. Altana beneficially owns approximately 7% of the Company’s outstanding common stock.
      On October 27, 2005, the Company received a fully-signed Promissory Note executed by BYK-Chemie USA (“BYK”), a customer of the Company, in favor of the Company in an original principal amount of $1,597,420. The proceeds of the Promissory Note are to be used to buy, install and commission certain equipment which is then to be used for fulfillment of orders by BYK and other uses. The outstanding principal balance of the Promissory Note is payable in three equal installments on January 30, 2009, April 30, 2009 and December 31, 2009. Interest accrues and is payable on a quarterly basis one year after the equipment referenced above is installed at the rate of 100 basis points over the average daily London Inter-Bank Offered Rate for the preceding quarter.
PROPOSAL 2
AMENDMENT TO CERTIFICATE OF INCORPORATION
TO INCREASE AUTHORIZED SHARES OF COMMON STOCK
      The Board of Directors has approved and recommends that the shareholders adopt an amendment to the Company’s Certificate of Incorporation to increase the total authorized shares of common stock of the Company from 25,000,000 to 30,000,000. The Company is currently authorized to issue 24,088 shares of preferred stock and the proposed amendment will not affect this authorization. The form of the proposed amendment is included as Exhibit A of this Proxy Statement.
      If the amendment is adopted, it will become effective upon the filing of a Certificate of Amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware.
      Purpose of the Proposed Amendment — Presently, the Board of Directors has no immediate or specific plans to issue the additional authorized shares of common stock. The Board desires, instead, to have the shares available to provide the Company with flexibility in responding to potential business opportunities in the future. The additional shares may be used for various purposes at the direction of the Board of Directors, when such issuance is deemed to be in the best interests of the Company. These purposes may include: establishing strategic relationships with other companies, expanding business or product lines through the acquisition of other businesses or products, and other corporate purposes.

Table of Contents

      The additional shares of common stock to be authorized by adoption of the amendment would have rights identical to the currently outstanding shares of common stock. Adoption of the proposed amendment and issuance of the common stock would not directly affect the rights of the holders of currently outstanding common stock, but effects incidental to the increase are possible. The issuance may decrease the proportionate holdings of existing stockholders and could have the effect of diluting voting power per share.
      Required Vote — To be approved, Proposal 2 must receive “For” votes from a majority of the shares outstanding on the record date. As a result, abstentions and broker non-votes will have the same effect as a vote “Against” such proposal.
PROPOSAL 3
AMENDMENT TO THE 2004
EQUITY COMPENSATION PLAN
      The Compensation and Governance Committee has approved and recommends that the shareholders adopt an amendment to the Company’s 2004 Equity Compensation Plan (the “Plan”). The proposed amendment to the Plan would (a) increase the number of shares available for grants under the Plan to 1,200,000, (b) increase the yearly cap on grants available under the Plan from 200,000 to 300,000 shares (subject to existing exceptions contained in the Plan), and (c) decrease the cap on grants to any individual in any year from 15% of any class to 10% of any class. The amendment would not change any other aspects of the Plan.
      To effect the amendment to the Plan, the first clause of the second sentence of Section 1.3(a)(i) would be amended to read as follows: “Subject to adjustments provided in Section 1.3(b) below, the aggregate number of Shares available for Grants under the Plan shall be 1,200,000 Shares.” Section 1.3(a)(ii)(A) of the Plan will also be amended to read: “Subject to adjustments as provided in Section 1.3(b) below, the maximum aggregate number of Shares that shall be subject to Grants made under this Plan during any calendar year shall be 300,000.” Finally, the first sentence of Section 1.3(a)(ii)(B) of the Plan would be amended to read: “No Grantee shall receive more than ten (10) percent of the aggregate number of any class of Grants made during any calendar year.”
      Purpose of the Amendment — The Company’s Board believes that the proposed amendment will strengthen the Company’s continued capacity to attract and retain the services of key employees who will contribute to the Company’s long-term growth and financial success. The Board recognizes that there is significant competition among high-technology businesses for talented employees and that these employees play an important role in maintaining the Company’s technology leadership position in nanomaterials and advanced nanoengineered products. The Board believes that the equity compensation available under the Plan, and the enhanced flexibility provided by the amendment, is vital to our ability to secure and build the Company’s talented human resources and thereby remain competitive and a technology leader in our industry.
      Vote Required — The NASD Marketplace Rules require shareholder approval when an equity compensation plan is materially amended. As a Result, Proposal 3 must receive “For” votes from a majority of the shares represented in person or by proxy to become effective. If you abstain from voting, it will have the same effect as an “Against” vote. Broker non-votes will not be considered present and entitled to vote, and will not have any effect for purposes of determining whether Proposal 3 has been approved.
MISCELLANEOUS AND OTHER MATTERS
      Solicitation — The cost of this proxy solicitation will be borne by the Company. The Company may request banks, brokers, fiduciaries, custodians, nominees and certain other record holders to send proxies, proxy statements and other materials to their principals at the Company’s expense. Such banks, brokers, fiduciaries, custodians, nominees and other record holders will be reimbursed by the Company for their reasonable out-of-pocket expenses of solicitation. The Company does not anticipate that costs and expenses

incurred in connection with this proxy solicitation will exceed an amount normally expended for a proxy solicitation for an election of directors in the absence of a contest.
      Proposals of Stockholders — Proposals of stockholders (1) intended to be considered at the Company’s 2007 Annual Meeting of Stockholders (the “2007 Annual Meeting”) and (2) to be considered for inclusion in the Company’s proxy statement and proxy for the 2006 Annual Meeting, must be received by the Secretary of the Company on or before January 3, 2007. If a stockholder submits a proposal to be considered at the 2007 Annual Meeting other than in accordance with Rule 14a-8 under the Securities Exchange Act of 1934, as amended, and does not provide notice of such proposal to the Company by March  19, 2007, the holders of any proxy solicited by the Company’s Board of Directors for use at such meeting will have discretionary authority to vote with respect to any proposal as to which timely notice is not given.
      Independent Certified Public Accountants — The Board of Directors, upon the recommendation of the Audit and Finance Committee, has appointed McGladrey and Pullen, LLP, independent certified public accountants, as auditors of the Company’s financial statements for the year ended December 31, 2006. McGladrey and Pullen, LLP has been engaged as auditors for the Company beginning in November 2001. In addition to audit services, McGladrey & Pullen, LLP also provided certain non-audit services to Nanophase Technologies Corporation in relation to the 2004 fiscal year. The Audit and Finance Committee has considered whether the provision of these additional services is compatible with maintaining the independence of McGladrey & Pullen, LLP. The following fees were incurred by Nanophase Technologies Corporation for the services of McGladrey & Pullen, LLP in relation to the 2004 fiscal year.
      Audit Fees. The aggregate amount billed by our principal accountant, McGladrey & Pullen, LLP, for audit services performed during the fiscal years ended December 31, 2005 and 2004 was $238,000 and $339,140, respectively. Audit services include the auditing of financial statements, quarterly reviews, statutory audits and the preparation of consents and review of registration statements.
      Audit Related Fees. McGladrey & Pullen, LLP did not perform audit related services during the fiscal years ended December 31, 2005 and 2004. Audit related services would include employee benefit plan audits, due diligence assistance, internal control review assistance and audit or attestation services not required by statute or regulation.
      Tax Fees. Total fees billed by RSM McGladrey, Inc. (an affiliate of McGladrey & Pullen, LLP) for tax related services for the fiscal years ended December 31, 2005 and 2004 were $7,575 and $6,500, respectively. These services include tax related research and general tax services in connection with transactions and legislation.
      All Other Fees. Other than those fees described above, there were no other fees billed for services performed by McGladrey & Pullen, LLP during the fiscal years ended December 31, 2005 and 2004.
      All of the fees described above were approved by Nanophase’s Audit and Finance Committee.
      Audit and Finance Committee Pre-Approval Policies and Procedures. Nanophase’s Audit and Finance Committee pre-approves the audit and non-audit services performed by McGladrey & Pullen, LLP, our principal accountants, and RSM McGladrey, Inc. (an affiliate of McGladrey & Pullen, LLP) in order to assure that the provision of such services does not impair McGladrey & Pullen, LLP’s independence. Unless a type of service to be provided by McGladrey & Pullen, LLP and RSM McGladrey, Inc. (an affiliate of McGladrey & Pullen, LLP) has received general pre-approval, it will require specific pre-approval by the Audit and Finance Committee. In addition, any proposed services exceeding pre-approval cost levels will require specific pre-approval by the Audit and Finance Committee. The term of any pre-approval is 12 months from the date of pre-approval, unless the Audit and Finance Committee specifically provides for a different period. The Audit and Finance Committee will periodically revise the list of pre-approved services, based on subsequent determinations, and has delegated pre-approval authority to the Chairman and Vice Chairman of the Audit and Finance Committee. In the event the Chairman or Vice Chairman exercises such delegated authority, they shall report such pre-approval decisions to the Audit and Finance Committee at its next scheduled meeting. The Audit and Finance Committee does not delegate its responsibilities to pre-approve services performed by the independent auditor to management.

      Other Business — The Board of Directors is not aware of any other matters to be presented at the Annual Meeting other than those mentioned in this Proxy Statement and the Company’s Notice of Annual Meeting of Stockholders enclosed herewith. If any other matters are properly brought before the Annual Meeting, however, it is intended that the persons named in the proxies will vote such proxies as the Board of Directors directs.
      Section 16(a) Beneficial Ownership Reporting Compliance — Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requires the Company’s officers (as defined under Section 16), directors and persons who beneficially own greater than 10% of a registered class of the Company’s equity securities to file reports of ownership and changes in ownership with the Securities and Exchange Commission. Based solely on a review of the forms it has received and on written representations from certain reporting persons that no such forms were required for them, the Company believes that during 2005 all Section 16 filing requirements applicable to its officers, directors and 10% beneficial owners were complied with by such persons.
      Additional Information — The Company will furnish without charge a copy of its Annual Report on Form 10-K for its year ended December 31, 2005, as filed with the Commission, upon the written request of any person who is a stockholder as of the Record Date, and will provide copies of the exhibits to such Form 10-K upon payment of a reasonable fee which shall not exceed the Company’s reasonable expenses in connection therewith.
