This Amendment No. 4 to Schedule 13D, filed on behalf of Robert A. Day, hereby amends the Schedule 13D Amendment No. 3 filed on February 24, 2003:


Item 2.	Identity and Background
This statement is being filed by Robert A. Day, an individual. Mr. Day is a director of the Issuer.
Mr. Day may be a person deemed to control Oakmont Corporation, a California corporation and an Investment Adviser registered under Section 203 of the Investment Advisers Act of 1940 (“Oakmont”), although he disclaims beneficial ownership of any securities owned by Oakmont. Oakmont engages in various aspects of the securities business, primarily as the investment advisor to various institutional and individual clients and as the managing general partner of various investment partnerships. Mr. Day and Oakmont are hereafter referred to as (“Day”).
Item 3.	Source and Amount of Funds or Other Consideration
Mr. Day paid an aggregate of $641,025 in personal funds to purchase 242,813 of the Issuer's common shares at a price per share of $2.64 on June 25, 2003 in a private, non-Issuer transaction.
Oakmont paid an aggregate of approximately $321,538 (including brokerage commissions) of client managed funds, to purchase 107,200 of the Issuer's common shares through the Nasdaq National Market on August 25, 2003 through September 2, 2003.
Item 4.	Purpose of Transaction
Day has purchased and holds the securities reported by it for investment for one or more accounts over which it has shared, sole, or both investment and/or voting power, for its own account or for both accounts.
Day may, from time to time, acquire additional securities of the Issuer in open market or privately negotiated transactions, depending on existing market conditions and other considerations that Day may deem relevant. Day intends to review the Issuer on a continuing basis and, depending upon the price and availability of the Issuer’s common shares, subsequent developments affecting the Issuer, the Issuer’s business and prospects, other investment and business opportunities available to Day, general stock market and economic conditions, tax consideration and other factors deemed relevant, may decide to increase or decrease the size of investment in the Issuer.
Other than as described above, Day does not have any present plans or proposals which relate to or would result in any transaction, change or event specified in clauses (a) through (j) of Item 4 of the Schedule 13D form.

Item 5.	Interest in Securities of the Issuer
(a) The aggregate number of securities to which this Schedule 13D relates is 7,113,816 shares of the Issuer’s common shares (the “Securities”), representing approximately 21.1% of the Issuer’s common shares. As of the date of this Schedule 13D, Day beneficially owns the Securities as follows:

Name	Shares of Common Stock	% of Class of Common Stock

Robert A. Day	4,891,316	14.5	%
Oakmont	2,222,500	6.6	%

Mr. Day may be deemed to have beneficial ownership of the Securities beneficially owned by Oakmont although he specifically disclaims such beneficial ownership. Also, on August 28, 2003, Mr. Day contributed 250,000 of the Securities to an irrevocable trust of which he is the trustee. Mr. Day retains sole voting and dispositive control over the Securities held in the trust during the trust’s term and is deemed to have indirect beneficial ownership of such Securities. Furthermore, 4,499 of the Securities that Mr. Day beneficially owns are held pursuant to options exercisable within the next 60 days, which options Mr. Day was granted under the Stock Option Plan for Outside Directors of the Company.

(b) Day has the sole power to vote or direct the vote and sole power to dispose or to direct the disposition of the Securities reported for it, either for its own benefit or for the benefit of its investment clients or its partners, as the case may be.

(c) Information with respect to all transactions in the Securities that were effected during the past sixty days or since the most recent Schedule 13D filing by Day is set forth on Schedule I annexed hereto and incorporated herein by reference.

(d) The investment advisory clients of Oakmont have the sole right to receive and, subject to the notice, withdrawal and/or termination provisions of such advisors, and partnership arrangements, the sole power to direct the receipt of dividends from, and the proceeds of sale of, any of the Securities beneficially owned by Day. No such client or partner has an interest by virtue of such relationship that relates to more than 5% of the Securities. Mr. Day does not have a pecuniary interest in any of the Securities reported herein as owned by Oakmont and disclaims any beneficial interest therein.

Signature

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
