Item 4. Purpose of Transaction

On January 28, 2005, CCM sent the Nominating and Corporate Governance Committee of the Issuer's Board of Directors a letter. In the letter CCM stated that Evan Marwell, a Managing Director and Senior Securities Analyst of CCM, is interested in joining the Issuer's Board of Directors. A copy of the January 28, 2005, letter is attached to this Schedule as Exhibit B.

On March 29, 2005, counsel for the Issuer sent counsel for CCM a letter stating the Nominating and Governance Committee of the Issuer's Board of Directors had determined not to enlarge the Issuer's Board of Directors to add Mr. Marwell, and that the Committee would again consider Mr. Marwell's request before the Issuer's 2005 annual meeting of stockholders.

On April 1, 2005, CCM sent the Issuer's Corporate Secretary a letter demanding the right, pursuant to Section 220 of the Delaware General Corporation Law, to inspect certain records and documents of the Issuer and to make copies or extracts therefrom. The letter states that the purpose of the demand is to permit CCM to communicate with other stockholders of the Issuer on matters relating to their interests as stockholders, including, but not limited to, and subject to compliance with applicable law, the composition of the Issuer's Board of Directors, the terms of the Issuer's certificate of incorporation and bylaws, and the enhancement of stockholder value. A copy of the April 1, 2005, letter is attached to this Schedule as Exhibit C.

On April 7, 2005, counsel for the Issuer sent CCM a letter stating that the brokerage account statement excerpts attached to CCM's April 1, 2005 letter did not sufficiently identify CCM as the owner of the relevant brokerage accounts.

On April 13, 2005, CCM sent the Issuer's Corporate Secretary a letter demanding the right demanded in its April 1, 2005 letter and attaching additional documentary evidence of CCM's ownership of Common Stock of the Issuer. A copy of the April 13, 2005, letter is attached to this Schedule as Exhibit D.

On May 20, 2005, CCM sent the Issuer's Corporate Secretary a letter giving notice of CCM's proposal to nominate Evan Marwell and Anthony Swei for election as directors of the Issuer at the 2005 annual meeting of the Issuer's stockholders on June 23, 2005, in opposition to the slate of director nominees submitted for election by the Issuer's incumbent board of directors. The letter also stated that CCM intends to solicit proxies from the Issuer's stockholders in support of its proposal using CCM's own proxy statement and other soliciting materials. A copy of the May 20, 2005, letter is attached to this Schedule as Exhibit E.

The Filers acquired the Stock for investment purposes, and such purchases were made in the Filers' ordinary course of business. In pursuing such investment purposes, the Filers may further purchase, hold, vote, trade, dispose or otherwise deal in the Stock at times, and in such manner, as they deem advisable to benefit from changes in market prices of such Stock, changes in the Issuer's operations, business strategy or prospects, or from sale or merger of the Issuer. To evaluate such alternatives, the Filers routinely will monitor the Issuer's operations, prospects, business development, management, competitive and strategic matters, capital structure, and prevailing market conditions, as well as alternative investment opportunities, liquidity requirements of the Filers and other investment considerations. Consistent with their investment research methods and evaluation criteria, the Filers may discuss such matters with management or directors of the Issuer, other shareholders, industry analysts, existing or potential strategic partners or competitors, investment and financing professionals, sources of credit and other investors. Such factors and discussions may materially affect, and result in, the Filers' modifying their ownership of the Stock, exchanging information with the Issuer pursuant to appropriate confidentiality or similar agreements, proposing changes in the Issuer's operations, governance or capitalization, or in proposing one or more of the other actions described in paragraphs (a) through (j) of Item 4 of Schedule 13D. The Filers reserve the right to formulate other plans and/or make other proposals, and take such actions with respect to their investment in the Issuer, including any or all of the actions set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D, or acquire additional Stock or dispose of all the Stock beneficially owned by them, in public market or privately negotiated transactions. The Filers may at any time reconsider and change their plans or proposals relating to the foregoing.

The beneficial ownership of the Stock by each Filer at the date hereof is reflected on that Filer's cover page.

The Filers effected the following transactions in the Stock in open market transactions on the dates indicated, and such transactions are the only transactions in the Stock by the Filers since 60 days before date on cover page: N/A

Item 6. Contracts, Arrangement, Understandings or Relationships with Respect to Securities of the Issuer

CCM is an investment adviser with discretionary authority over client accounts. Some of CCM's client accounts are limited partnerships for which CCM serves as the general partner pursuant to agreements providing to CCM the authority, among other things, to invest the funds of such partnership in the Stock, to vote and dispose of Stock. Other clients are investment accounts subject to investment advisory agreements providing CCM the authority to invest the assets of the account in the Stock, to vote and dispose of the Stock.
