1.       BASIS OF PRESENTATION
         ---------------------

                  The accompanying financial statements are unaudited, but
         reflect all adjustments which, in the opinion of management, are
         necessary for a fair presentation of financial position and the results
         of operations for the interim periods presented. All such adjustments
         are of normal and recurring nature. The results of operations for any
         interim period are not necessarily indicative of the results attainable
         for a full fiscal year.

2.       INCOME (LOSS) PER SHARE
         -----------------------

                  Per share information is computed based on the weighted
         average number of shares outstanding during the period with net income
         (loss) reduced by cumulative preferred stock dividends.

3.       HOLDINGS
         --------

4.       INTERIM FINANCIAL STATEMENT DISCLOSURES
         ---------------------------------------

                  Certain information and footnote disclosures normally included
         in financial statements presented in accordance with generally accepted
         accounting principles have been condensed or omitted from the
         accompanying unaudited interim financial statements. Reference is made
         to the Company's audited financial statements for the year ended
         December 31, 1997 included in the Company's Annual Report on Form
         10-KSB/A filed with the Securities and Exchange Commission on April 30,
         1998.

5.       RESTATEMENT
         -----------

                  The financial statements for the quarter ended March 31, 1997
         have been restated to reflect the retroactive adoption of SFAS No. 128,
         "Earnings per Share" and for the effect of a change in accounting
         previously reported in the Company's Form 10-KSB/A for the year ended
         December 31, 1997.

6.       ADOPTION OF ACCOUNTING STANDARD
         -------------------------------

                  During the quarter ended March 31, 1998, the Company adopted
         SFAS No. 130, "Reporting Comprehensive Income". Statement No. 130
         requires the reporting of comprehensive income in addition to net
         income from operations. Comprehensive income is a more inclusive
         financial reporting methodology that includes disclosures of certain
         financial information that historically has not been recognized in the
         calculation of net income. The Company has included a Statement of
         Comprehensive Income in the accompanying financial statements.
