These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of XOMA Corporation as of December 31, 1997 and 1996, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 1997 in conformity with generally accepted accounting principles.

XOMA CORPORATION NOTES TO FINANCIAL STATEMENTS 1. OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Business XOMA Corporation ("XOMA" or the "Company") is a biopharmaceutical company developing products to treat infections, infectious complications of traumatic injury and surgery, and immunologic and inflammatory disorders. The Company's products are presently in various stages of development and all are subject to regulatory approval before the Company can commercially introduce any products. There can be no assurance that any of the products under development by the Company will be developed successfully, obtain the requisite regulatory approval or be successfully manufactured or marketed. The Company's cash position and resulting investment income are sufficient to finance the Company's currently anticipated needs for operating expenses, working capital, equipment and current research projects for in excess of one year. The Company continues to evaluate strategic alliances, potential partnerships, and financing arrangements which would further strengthen its competitive position and provide additional funding. The Company cannot predict whether or when any such alliance(s), partnership(s) or financing(s) will be consummated or whether additional funding will be available when required. Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. Net Loss Per Common Share Net loss per common share is based on the weighted average number of common shares outstanding in accordance with Financial Accounting Standard No. 128. -10- Reconciliation of the numerator and the denominator of basic and diluted net loss per share was derived as follows (in thousands, except per share amounts): Amount per Year ended December 31 Loss Shares share - - ---------------------- ---- ------ ---------- 1997 Net loss $(15,765) Preferred stock dividends (1,566) -------- Basic and diluted loss available to common shareholders $(17,331) 39,679 $(0.44) ======== 1996 Net loss $(29,110) Preferred stock dividends (180) Basic and diluted loss available to common shareholders $(29,290) 32,493 $(0.90) ======== 1995 Net loss $(22,472) Preferred stock dividends (586) -------- Basic and diluted loss available to common shareholders $(23,058) 23,671 $(0.97) ======== The following potentially dilutive outstanding securities were not considered in the computation of basic and diluted loss per share because they would be antidilutive for each of the years ended December 31: Amount (in thousands): 1997 1996 1995 - - --------------------- ---- ---- ---- Weighted average options for shares of common stock 3,627 3,162 2,992 Weighted average warrants for shares of common stock 295 29 983 Common shares issuable to satisfy obligations 344 -- -- Shares of convertible preferred stock 1,167 -- 7,807 Convertible notes, debentures, and related interest $24,773 $13,813 $6,500 Subsequent to December 31, 1997 the Company issued 344,168 shares of common stock in settlement of a securities class action lawsuit(see Note 6). Cash and Cash Equivalents For the purpose of the statements of cash flows, the Company considers all highly liquid debt instruments with maturities of three months or less at the time the Company acquires them to be cash equivalents, -11- except when such debt instruments are part of a portfolio of investments managed by an independent, outside investment manager, in which case these instruments are classified as short-term investments. Supplemental Cash Flow Information Cash paid for interest was $0.1 million, $0.2 million, and $0.1 million during the years ended December 31, 1997, 1996, and 1995, respectively. In addition, during the years ended December 31, 1997, 1996 and 1995, the Company had the following non-cash financing and investing activities (in thousands): 1997 1996 1995 ---- ---- ---- Stock contribution to the 401(k) and management $ 319 $ 395 $ 434 incentive plans (Notes 4 and 9) Stock issuance cost paid with common or preferred stock -- -- 8 (Note 4) Unrealized loss(gain) on investments (42) (45) 125 Conversion of debentures to common stock -- 5,861 -- Interest paid in common stock -- 59 -- Conversion of preferred stock to common stock 830 28,807 12,607 Dividends paid in common stock 15 180 781 Property and Equipment Property and equipment, including equipment under capital leases, are stated at cost. Equipment depreciation is calculated using the straight-line method over the estimated useful lives of the assets (five to seven years). Leasehold improvements, buildings, and building improvements are amortized and depreciated using the straight-line method over the shorter of the lease terms or the useful lives (one to seven years). Property and equipment consist of the following (in thousands): December 31 1997 1996 ---- ---- Equipment $15,545 $14,500 Leasehold and building improvements 14,836 14,483 Construction-in-progress 97 208 ------ ------- 30,478 29,191 Less accumulated depreciation and amortization 25,914 24,093 ------- ------- Property and equipment, net $ 4,564 $ 5,098 ======= ======= Assets held for sale $ 4,442 $ 4,442 ======= ======= Long-lived Assets In accordance with FASB Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of," the Company records impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. -12- In 1994, the Company discontinued development of its CD5 Plus(TM) product and began to evaluate the related production facility for alternative uses, including a possible sale of the facility. During 1995, the Company determined that the events and circumstances indicated that the value of the facility had become impaired. As a result, it recorded a charge of $2.4 million in "Other income and expense," reflecting the difference between the then current carrying value of the facility and its estimated realizable value. At that time, the estimated realizable value was determined based on the sales price that management had estimated it could receive from a potential buyer of the facility. The Company does not currently believe that the carrying amount is in excess of net realizable value, as it continues to reflect the estimated price that could be received from a buyer. While the facility has not been sold, it continues to be available for sale and there is no indication the current carrying value is inappropriate. If the Company sells the facility, the amount the Company will ultimately realize could differ materially from the carrying amount. The Company is also considering adapting the facility to expand production of its NEUPREX(R) product. This adaptation, if pursued, is estimated to cost significantly less than a new facility. The Company's current estimate of net cash flows from NEUPREX(R) that would be manufactured in the facility exceeds the current carrying value of the facility plus anticipated costs to renovate it for NEUPREX(R) production. If the Company pursues this alternative, the actual net cash flows that the Company will ultimately realize as well as the estimated costs to renovate the facility could differ materially from the estimated amounts. Accrued Liabilities Accrued liabilities consist of the following (in thousands): December 31 1997 1996 ---- ---- Accrued legal costs $ 198 $ 661 Accrued dividends 810 586 Accrued payroll costs 1,986 1,573 Provision for litigation settlement 2,028 2,500 Clinical trial costs 1,203 521 Other 187 303 ------ ------ $6,412 $6,144 ====== ====== Activities through December 31, 1997 affecting the provision for litigation settlement established in 1996 are as follows (in millions): Original amount $2.5 Charges against the accrual 0.2 Adjustment to the accrual 0.3 In December 1997, the Company elected to settle the claim through the issuance of 344,168 shares of common stock which resulted in a $0.3 million reduction in the accrual. The liability was eliminated in January 1998 upon issuance of the shares. Revenue Recognition Revenue related to collaborative agreements is recognized when earned under the terms of the agreement and when performance obligations have been met and related payments are receivable and non-refundable. Non-refundable licenses and milestone fees are recognized as revenue when the payments are receivable and the Company has no future obligations to perform. In both cases, receivable amounts are rec- -13- ognized when collection is assured. The excess of total research and development expense over revenues recognized under collaborative agreements amounted to $29.9 million, $26.4 million, and $22.1 million for the years 1997, 1996, and 1995, respectively. Reclassifications Certain reclassifications have been made to conform the prior years to the 1997 presentation. -14- New Accounting Standards In June 1997, the Financial Accounting Standards Board issued a final statement on reporting comprehensive income. The adoption of the standard as required on January 1, 1998 will not have a material impact on the Company's financial statements. 2. CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS On December 31, 1997 and 1996, cash and cash equivalents consisted mostly of money market mutual funds. The Company follows a policy of investing only in marketable debt securities and holding them to maturity; however, since the Company has from time to time sold certain securities to meet cash requirements or improve investment diversification, the Company's short-term investments have been categorized as available-for-sale. The aggregate fair values, amortized cost, gross unrealized holding gain, and gross unrealized holding loss of the major types of debt securities at December 31, 1997 were as follows (in millions): Gross Unrealized Holding ------------------------ Fair Amortized Value Cost Gain Loss ----- ---- ---- ---- U.S. Treasury Securities $9.5 $9.5 $ -- $ -- Corporate Bonds and Other 8.4 8.4 -- -- The contractual maturities of the Company's debt securities as of December 31, 1997 were as follows (in millions): Less than 1 year $11.4 From 1 to 2 years 4.0 More than 2 years 2.5 During the year ended December 31, 1997, gross realized losses on available-for-sale securities were negligible and the net change in the unrealized gain or loss was negligible. Gross realized gains were negligible. Gains and losses are determined on a specific identification basis. As of December 31, 1997, short-term investments included $0.1 million in certificates of deposit which guaranteed a standby letter of credit. 3. RESEARCH AND DEVELOPMENT AGREEMENTS In April 1996, the Company entered into a collaborative agreement with Genentech, Inc. ("Genentech") to jointly develop hull24 (anti-CD11a), for treatment of psoriasis and for organ transplant rejection. In connection therewith, Genentech purchased 1.5 million shares of common stock for approximately $9 million and has agreed to fund the Company's development costs for hull24 until the completion of Phase II clinical trials through a series of convertible subordinated notes. During 1996, Genentech made loans totaling $13.5 million ($5.0 and $8.5 million, respectively, for funding 1996 and 1997 clinical trials and development costs) to XOMA under this arrangement. An additional loan of $10.0 million was made in December 1997 to fund 1998 costs. Under the terms of the agreement, the Company will scale up and develop hull24 and bring it through Phase II clinical trials. After completion of Phase II trials, Genentech will determine the product's future development strategy. -15- In May 1996, the Company announced the granting of an exclusive license to Genentech, including a sublicense to IDEC Pharmaceuticals Corporation, to intellectual property covering the therapeutic use of chimeric IgG1 antibodies specific to the CD20 antigen on the surface of human B-cells. The Company received an initial cash payment of $3.0 million and the right to receive royalties on the sale of products employing the anti-CD20 technology that are sold in the United States and in other countries where the Company held relevant patents. In December 1997, the Company assigned the related patents and royalty rights to Pharmaceutical Partners, LLC for $17.0 million and recognized this amount as license fee revenue. In June 1994, the Company assigned its exclusive worldwide rights in T cell receptor ("TCR") peptide technology to Connetics. The Company received a promissory note in the amount of $1.4 million and warrants to purchase 450,000 shares of Connetics. stock, and will receive milestone payments and royalties on product sales. In 1995, the Company received an additional note in the amount of $0.8 million pursuant to the terms of the original assignment. The notes were paid in full in February 1996 and the warrants cancelled. In 1995, XOMA and Pfizer modified the funding arrangement of the then current E5(R) clinical trial and of certain patent litigation costs. As a result, the Company recorded a $4.3 million gain in Other income. In June 1997, the Company announced that Pfizer had ended its agreements with the Company relating to monoclonal antibody-based products for the treatment of gram-negative sepsis, which resulted in the elimination of the contingent $22.4 million liability to Pfizer. XOMA has granted licenses to a number of biotechnology and pharmaceutical companies for use of patented and proprietary technologies relating to a bacterial expression system used to manufacture recombinant pharmaceutical products. Licensees include: Affymax Research Institute, Cantab Pharmaceuticals Research Ltd, Eli Lilly and Company, Enzon, Inc., the Hoechst Group, ICOS Corporation, Pasteur Merieux Serums & Vaccins, and The Pharmacia & Upjohn Group. 4. CAPITAL STOCK Common Stock In April 1996, Genentech purchased 1.5 million shares of common stock for approximately $5.90 per share in connection with the collaborative agreement to develop jointly Genentech's anti-CD11a monoclonal antibody product, hull24.

Management Incentive Compensation Plan The Board of Directors of the Company established a Management Incentive Compensation Plan effective July 1, 1993 (as amended, the "Incentive Plan"), in which management employees (other than the Chief Executive Officer), as well as certain additional discretionary participants chosen by the Chief Executive Officer, are eligible to participate. Awards under the Incentive Plan vest over a three-year period with 50% of each award payable on a date to be determined, expected to be in the first quarter of the following fiscal year, and 25% payable on each of the next two annual distribution dates, so long as the participant continues to participate in the Incentive Plan. The amounts charged to expense under the Incentive Plan were $0.8 million, $0.7 million and $0.6 million for the plan years 1997, 1996 and 1995 respectively. Stockholder Rights Plan In October 1993, the Company's Board of Directors unanimously adopted a Stockholder Rights Plan (the "Rights Plan"). Under the Rights Plan, Preferred Stock Purchase Rights ("Rights") were distributed as a dividend at the rate of one Right for each share of the Company's Common Stock held of record as of the close of business on November 12, 1993. Each Right entitles the registered holder of Common Stock to buy a fraction of a share of the new series of Preferred Stock (the "Series A Preferred Stock") at an exercise price of $30.00, subject to adjustment. The Rights will be exercisable, and will detach from the Common Stock, only if a person or group acquires 20 percent or more of the Common Stock, announces a tender or exchange offer that if consummated will result in a person or group beneficially owning 20 percent or more of the Common Stock, or if the Board of Directors declares a person or group owning 10 percent or more of the outstanding shares of Common Stock to be an Adverse Person (as defined in the Rights Plan). Once exercisable, each Right will entitle the holder (other than the acquiring person) to purchase units of Series A Preferred Stock (or, in certain circumstances, common stock of the acquiring person) with a value of twice the Rights exercise price. The Company will generally be entitled to redeem the Rights at $.001 per Right at any time until the close of business on the tenth day after the Rights become exercisable. The Rights will expire at the close of business on December 31, 2002. 5. STOCK OPTIONS AND WARRANTS At December 31, 1997, the Company had three stock-based compensation plans, which are described below. The aggregate number of shares of Common Stock that may be issued under these plans is 5,300,000 shares. -18- Stock Option Plan Under the Company's amended 1981 Stock Option Plan (the "Option Plan"), qualified and non-qualified options of the Company's Common Stock may be granted to certain employees and other individuals as determined by the Board of Directors at not less than the fair market value of the stock at the date of grant. Options granted under the Option Plan may be exercised when vested and expire five years and two months to ten years from the date of grant or three months from the date of termination of employment. Options granted generally vest over five years. The Option Plan will terminate on November 15, 2001. As of December 31, 1997, options covering 3,132,386 shares of Common Stock were outstanding under the Option Plan. Restricted Stock Plan The Company also has a Restricted Stock Plan (the "Restricted Plan") which provides for the issuance of options or the direct sale of Common Stock to certain employees and other individuals as determined by the Board of Directors at not less than 85% of fair market value of the Common Stock on the grant date. Each option issued under the Restricted Plan will be a non-statutory option under the federal tax laws and will have a term not in excess of ten years from the grant date. Options granted generally vest over five years. The Restricted Plan will terminate on December 15, 2003. The Company has granted options with exercise prices at 85% of fair market value on the date of grant. Up to 1,200,000 shares are authorized for issuance under the Restricted Plan. As of December 31, 1997, options covering 537,479 shares of Common Stock were outstanding under the Restricted Plan. The Company amortizes deferred compensation, which is the difference between the issuance price or exercise price and the fair market value of the shares as determined by the Board of Directors at the date of sale or grant over the period benefited. Directors Stock Option Plan In 1992, the stockholders approved a Directors Stock Option Plan (the "Directors Plan") which provides for the issuance of options to purchase shares of Common Stock to non-employee directors of the Company at 100% of the fair market value of the stock on the date of the grant. Up to 150,000 shares are authorized for issuance during the term of the Directors Plan. Options vest on the date of grant and have a term of up to ten years. As of December 31, 1997, options for 50,000 shares of Common Stock were outstanding under the Directors Plan. The Company applies APB Opinion 25 and related interpretations in accounting for its plans. Accordingly, the financial statements reflect amortization of compensation resulting from options granted at exercise prices which were below market price at the grant date. Had compensation cost for the Company's stock-based compensation plans been based on the fair value at the grant dates for awards under these plans consistent with the provisions of FASB Statement 123, the Company's net loss and loss per share would have been increased to the pro forma amounts indicated below for the years ended December 31 (in thousands except per share amounts): 1997 1996 1995 ---- ---- ---- Net loss As reported $(15,765) $(29,110) $(22,472) Pro forma $(17,639) $(30,213) $(23,953) Net loss per share As reported $ (0.44) $ (0.90) $ (0.97) Pro forma $ (0.48) $ (0.94) $ (1.04) -19- The fair value of each option grant under these plans is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used for grants during the years indicated below: 1997 1996 1995 ---- ---- ---- Dividend yield 0% 0% 0% Expected volatility 71% 73% 73% Risk-free interest rate 6.3% 5.2% 7.6% Expected life 7 years 7 years 6 years A summary of the status of the Company's stock option plans as of December 31, 1997, 1996, and 1995, and changes during years ending on those dates is presented below: 1997 1996 1995 ---- ---- ---- OPTIONS: Shares Price* Shares** Price* Shares Price* ------ ------ -------- ------ ------ ------ Outstanding at beginning of year 3,196,150 $ 4.50 2,847,017 $ 4.50 3,000,692 $ 10.33 Granted (1) 1,750 5.36 2,500 4.84 34,000 2.29 (2) 671,000 6.68 499,750 4.97 2,204,605 2.53 (3) -- -- 145,333 5.00 1,250 2.94 Exercised (52,422) 2.72 (67,132) 2.68 (5,315) 2.40 Forfeited, Expired or Canceled (96,613) 4.33 (231,318) 6.40 (2,388,215) 9.97 ------ ------- --------- Outstanding at end of year 3,719,865 4.92 3,196,150 4.50 2,847,017 4.50 ========= ========= ========= Exercisable at end of year 2,317,321 1,816,185 1,310,938 ========= ========= ========= Weighted average fair value of options granted (1) 3.89 2.71 1.92 (2) 4.78 3.09 1.51 (3) -- 1.59 0.99 * Weighted-average exercise price ** Includes cancellation and granting of 1,820,385 new options (1) Option price less than market price on date of grant (2) Option price equal to market price on date of grant (3) Option price greater than market price on date of grant The Company adjusts for forfeitures as they occur. -20- The following table summarizes information about stock options outstanding at December 31, 1997: Options Outstanding Options Exercisable ------------------- ------------------- Range of Number Number -------- ------ ------ Exercise Prices Outstanding Life* Price** Exercisable Price** --------------- ----------- ----- ------- ----------- ------- $ 1.70 - 2.38 329,646 7.1 $ 2.36 184,472 $ 2.36 2.55 - 3.81 1,561,058 7.0 2.57 1,193,839 2.57 4.06 - 5.94 620,413 6.6 4.79 281,273 4.80 6.06 - 7.50 976,083 5.9 7.09 472,739 7.38 7.56 -13.25 75,700 7.9 8.92 28,033 10.98 16.36 - 22.75 154,965 2.8 18.68 154,965 18.68 26.50 - 26.50 2,000 3.3 26.50 2,000 26.50 -------------- - ---------- --- - ------ - ---------- ------ $ 1.70 - 26.50 3,719,865 6.5 $ 4.92 2,317,321 $ 5.01 * Weighted-average Remaining Contractual Life ** Weighted-average Exercise Price Warrants Warrants to purchase 486,000 shares of Common Stock were issued in conjunction with the issuance of the Series G Preferred in August 1997, all of which expire in August 2000, at an exercise price of $10.00 per share.

The Company issued warrants valued at $0.8 million in Paid-in capital to purchase 109,739 shares of Common Stock in conjunction with the issuance of the Series F Preferred, one-half of which expire on March 24, 1998 and the remainder expiring on September 24, 1999, at an exercise price of $7.29 per share. Warrants to purchase 1,810,980 shares of Common Stock issued in conjunction with the issuance of the Series B Preferred Stock in December 1993 expired on December 19, 1995.

COMMITMENTS AND CONTINGENCIES Clinical Trial Due to the termination of E5(R)development in mid-1997, the contingent $22.4 million in future reduced royalties from Pfizer has been eliminated. Collaborative Agreements and Royalties As of December 31, 1997, the Company has commitments under research agreements with universities and other research institutions that require the Company to fund research in the amount of $0.1 million through August 1998. Research and development expenses include research agreement expenses of approximately $0.2 million, $0.3 million, and $0.4 million for the years ended December 31, 1997, 1996 and 1995, -21- respectively. The Company is also obligated to pay royalties, ranging generally from 1.5% to 5% of the selling price of the licensed component and up to 25% of sublicense fee income, to various universities and other research institutions based on future sales or licensing of products that incorporate certain products and technologies developed by those institutions. Leases As of December 31, 1997, the Company leased administrative, research facilities, certain laboratory and office equipment under operating and capital leases expiring on various dates through 2008. Future minimum lease commitments are as follows (in thousands): Capital Leases Operating Leases -------------- ---------------- 1998 $ 753 $ 2,427 1999 -- 2,413 2000 -- 2,439 2001 -- 2,239 2002 -- 2,239 Thereafter -- 12,378 ----- ------- Net minimum lease payments 753 $24,135 ======= Less--Amount representing interest expense 46 ----- Present value of net minimum lease payments 707 Less--Current maturities 707 ----- Long-term capital lease obligations $ -- ===== Total rental expense was approximately $2.0 million, $2.0 million, and $2.3 million for the years ended December 31, 1997, 1996, and 1995, respectively. Legal Proceedings In the securities class action lawsuit Warshaw, et al. v. XOMA Corporation, et al., the defendants and plaintiffs reached an agreement on March 14, 1997 to settle all claims for $3.75 million in cash and $2.25 million in Common Stock. By order entered September 8, 1997, the United States District Court for the Northern District of California approved the settlement. All of the cash portion of the settlement has been paid by insurance into a settlement fund administered by an escrow agent. The claims administration process was deemed complete as of December 16, 1997, and on January 7, 1998, XOMA directed its stock transfer agent to issue and distribute to authorized claimants 344,168 shares of Common Stock in accordance with the terms of the court-approved settlement agreement. Liability Insurance The testing and marketing of medical and food additive products entails an inherent risk of allegations of product liability. XOMA believes that its product liability insurance levels are adequate for its clinical trial activity. XOMA will seek to obtain additional insurance, if needed, if and when the Company's products are commercialized; however, there can be no assurance that adequate insurance coverage will be available or be available at acceptable costs or that a product liability claim would not materially adversely affect the business or financial condition of the Company. The Company insures and indemnifies its directors and officers against actions brought against them as a result of their management of the Company's operations. There can be no assurance that adequate direct- -22- ors and officers insurance coverage will be available or be available at acceptable costs or that a claim against the directors and officers would not materially adversely affect the business or financial condition of the Company. 7. INCOME TAXES The significant components of net deferred tax assets and liabilities as of December 31, are as follows (in millions): 1997 1996 ---- ---- Property and equipment $ 2.3 $ 2.3 Purchased technology 5.0 5.7 Capitalized R&D expense 62.8 50.8 Accrued liabilities and other 2.3 1.4 Net operating loss carryforwards 61.7 66.8 R&D and other credit carryforwards 14.1 13.0 Valuation allowance (148.2) (140.0) ------- ------- Total deferred tax asset $ -- $ -- ======== ======== The net change in the valuation allowance was a $8.2 million and a $13.1 million increase for the years ended December 31, 1997 and 1996, respectively. XOMA's accumulated federal and state tax net operating losses ("NOLs") and credits as of December 31, 1997 are as follows: Amounts Expiration (in millions) Dates ------------- ----- Federal NOLs $ 186.4 2001-2013 Credits 10.3 1998-2013 State NOLs 26.5 1998-2003 Credits 3.8 2005-2013 For the year ended December 31, 1997 the Company had taxable income of $12.5 million and $11.1 million for Federal income tax and State tax, respectively. Except for the impact of Federal alternative minimum tax, which was not material, these taxable income amounts were offset by NOL and tax credit carryforwards. These amounts are subject to audit by federal and state tax authorities and could change. Certain future changes in the ownership of significant shareholders could limit utilization of the Company's tax NOLs and credits. 8. RELATED PARTY TRANSACTIONS In 1993, the Company granted a short-term, secured loan to an officer, director and stockholder of the Company. 9. DEFERRED SAVINGS PLAN Under section 401(k) of the Internal Revenue Code of 1986, the Board of Directors adopted, effective June 1, 1987, a tax-qualified deferred compensation plan for employees of the Company.

The Company may, at its sole discretion, make contributions each plan year, in cash or in shares of the Company's Common Stock in amounts which match up to 50% of the salary deferred by the participants. The expense of these contributions was $233,000, $243,000, and $326,000, for the years ended December 31, 1997, 1996 and 1995, respectively. -24- INDEX TO EXHIBITS Exhibit Number 23.1 Consent of Independent Public Accountants. -25-
