AVANT IMMUNOTHERAPEUTICS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MARCH 31, 2000 (1) NATURE OF BUSINESS AVANT Immunotherapeutics, Inc. ("AVANT") is a biopharmaceutical company engaged in the discovery, development and commercialization of products that harness the human immune response to prevent and treat disease. Our lead therapeutic program is focused on compounds that inhibit the inappropriate activity of the complement cascade, a vital part of the body's immune defense system. AVANT is also developing on its own a proprietary therapeutic vaccine for the management of atherosclerosis and Therapore(TM), a novel system for the delivery of immunotherapeutics for chronic viral infections and certain cancers. AVANT and its collaborators are developing vaccines using the proprietary adjuvants, Adjumer(R) and Micromer(R), for the prevention of respiratory syncytial virus (RSV), Lyme disease and several other vaccine targets. Through additional collaboration, we are also developing an oral human rotavirus vaccine and a cholera vaccine. The unaudited consolidated financial statements include the accounts of AVANT Immunotherapeutics, Inc. and its wholly owned subsidiary, Polmerix, Inc. All intercompany transactions have been eliminated. (2) INTERIM FINANCIAL STATEMENTS The accompanying unaudited consolidated financial statements for the three months ended March 31, 2000 and 1999 include the consolidated accounts of AVANT, and have been prepared in accordance with generally accepted accounting principles and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, the information contained herein reflects all adjustments, consisting solely of normal recurring adjustments, that are necessary to present fairly the financial positions at March 31, 2000 and December 31, 1999, the results of operations for the quarters ended March 31, 2000 and 1999, and the cash flows for the three months ended March 31, 2000 and 1999. The results of operations for the quarter ended March 31, 2000 are not necessarily indicative of results for any future interim period or for the full year. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted, although we believe that the disclosures included are adequate to make the information presented not misleading. The unaudited consolidated financial statements and the notes included herein should be read in conjunction with footnotes contained in AVANT's Annual Report on Form 10-K for the year ended December 31, 1999. Certain amounts in the 1999 results for the quarter ended March 31, 1999 have been reclassified to provide consistent presentation with the 2000 results for the quarter ended March 31, 2000. 6

The decision to license TP10 resulted in a $6 million payment by Novartis which was received by AVANT in January 2000. The payment included an equity investment of $2,307,700 for 1,439,496 shares of our common stock at $1.60 per share and a license fee of $3,692,300. We are amortizing the license fee over twenty-four quarters, the projected development period for the licensed field. (6) NET INCOME (LOSS) PER SHARE Consistent with SFAS 128, basic earnings (loss) per share amounts are based on the weighted average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share amounts are based on the weighted average number of shares of common stock and the potential common stock outstanding during the period. We have excluded all of the potential common stock shares from the calculation of diluted weighted average share amounts for the three-month periods ended March 31, 2000 and 1999 as its inclusion would have been anti-dilutive. 7

SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995: STATEMENTS CONTAINED IN THE FOLLOWING, ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, THAT ARE NOT HISTORICAL FACTS MAY BE FORWARD-LOOKING STATEMENTS THAT ARE SUBJECT TO A VARIETY OF RISKS AND UNCERTAINTIES. THERE ARE A NUMBER OF IMPORTANT FACTORS THAT COULD CAUSE THE ACTUAL RESULTS TO DIFFER MATERIALLY FROM THOSE EXPRESSED IN ANY FORWARD-LOOKING STATEMENTS MADE BY AVANT. THESE FACTORS INCLUDE, BUT ARE NOT LIMITED TO: (I) OUR ABILITY TO SUCCESSFULLY COMPLETE PRODUCT RESEARCH AND DEVELOPMENT, INCLUDING PRE-CLINICAL AND CLINICAL STUDIES, AND COMMERCIALIZATION; (II) OUR ABILITY TO OBTAIN SUBSTANTIAL ADDITIONAL FUNDING; (III) OUR ABILITY TO OBTAIN REQUIRED GOVERNMENTAL APPROVALS; (IV) OUR ABILITY TO ATTRACT MANUFACTURING, SALES, DISTRIBUTION AND MARKETING PARTNERS AND OTHER STRATEGIC ALLIANCES; AND (V) OUR ABILITY TO DEVELOP AND COMMERCIALIZE OUR PRODUCTS BEFORE OUR COMPETITORS. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW We are engaged in the discovery, development and commercialization of products that harness the human immune response to prevent and treat disease. Our products derive from a broad set of complementary technologies with the ability to inhibit the complement system, regulate T and B cell activity, and enable the creation and delivery of preventative and therapeutic vaccines. We are using these technologies to develop vaccines and immunotherapeutics that prevent or treat disease caused by infectious organisms, and drugs and treatment vaccines that modify undesirable activity by the body's own proteins or cells. ACQUISITION On August 21, 1998, we acquired Virus Research Institute, Inc. ("VRI"), a company engaged in the discovery and development of systems for the delivery of vaccines and immunotherapeutics, and novel vaccines for adults and children. AVANT issued 14,036,400 shares and warrants to purchase 1,811,200 shares of it's common stock in exchange for all of the outstanding common stock of VRI, on the basis of 1.55 shares and .20 of a warrant to purchase one share of AVANT's common stock for each share of VRI common stock. The acquisition has been accounted for as a purchase. Consequently, the purchase price was allocated to the acquired assets and assumed liabilities based upon their fair value at the date of acquisition. The excess of the purchase price over the tangible assets acquired was assigned to collaborative relationships, work force and goodwill and is being amortized on a straight line basis over 12 to 60 months. An allocation of $44,630,000 was made to in-process research and development ("IPR&D") which represented purchased in-process technology which had not yet reached technological feasibility and had no alternative future use. The amount was charged as an expense in our financial statements during the third quarter of 1998. NEW DEVELOPMENTS COMPLEMENT INHIBITORS: In 1997, we entered into an agreement with Novartis relating to the development of TP10 for use in xenotransplantation (animal organs into humans) and allotransplantation (human organs into humans). We granted Novartis a two-year option to license TP10 with exclusive worldwide marketing rights (except Japan) in the fields of xenotransplantation and allotransplantation. In July 1999, Novartis exercised its option to license TP10 for use in the field of transplantation. In December 1999, the Novartis agreement was amended to include marketing rights for Japan. The decision to license TP10 resulted in a $6 million equity investment and license payment by Novartis which was received by AVANT in January 2000. Under the agreement, we may receive additional milestone payments of up to $14 million upon attainment of certain development and regulatory goals. We will also be entitled to royalties on product sales under the agreement. We have elected to independently develop and commercialize TP10 for pediatric cardiac surgery. In September 1999, we initiated an open-label, Phase I/II trial of TP10 in infants undergoing cardiac surgery for congenital heart defects. The trial will evaluate the ability of TP10 to mitigate the injury to the heart and other organs that occurs when patients are placed on cardiopulmonary bypass circuits. Patient enrollment in this Phase I/II trial was completed in January 2000. In March 2000, we received orphan drug designation for TP10 in 8

infants undergoing cardiac surgery. We expect to initiate a pivotal Phase III trial in this indication around the end of 2000. AVANT additionally plans to refine the TP10 dosing regimen in additional infants prior to starting the Phase III study. We also plan to initiate Phase II trials for adult cardiac surgery during the second half of 2000, with an expectation to partnering that program when additional clinical data are available. ATHEROSCLEROSIS TREATMENT VACCINE: We are developing a therapeutic vaccine against endogenous cholesteryl ester transfer protein ("CETP") which may be useful in reducing risks associated with atherosclerosis. CETP is a key intermediary in the balance of HDL and LDL. We are developing a vaccine (CETi-1) to stimulate an immune response against CETP which we believe may improve the ratio of HDL to LDL cholesterol and reduce the progression of atherosclerosis. We have conducted preliminary studies of rabbits which have demonstrated the ability of CETi-1 vaccine to elevate HDL and reduce the development of blood vessel lesions. In June 1999, we initiated a double-blind placebo controlled, Phase I clinical trial of our CETi-1 vaccine in adult volunteers. The object of the study is to demonstrate the safety of single administrations of the vaccine at four different dosage strengths. Patient enrollment in this Phase I trial was completed in February 2000. We plan to initiate a Phase II study during the second half of 2000. As clinical data becomes available, we plan to seek a corporate partner to complete development and to commercialize the vaccine. ROTAVIRUS VACCINE: Rotavirus is a major cause of diarrhea and vomiting in infants and children. No vaccine against rotavirus is currently on the market. In 1997, we licensed our oral rotavirus vaccine to SmithKline Beecham plc ("SmithKline"). In 1999, after our Phase II study demonstrated 89% protection in a study involving 215 infants, SmithKline paid us an additional license fee and assumed full responsibility for funding and performing all remaining clinical development. SmithKline has initiated Phase I/II bridging studies in Europe using its newly manufactured rotavirus vaccine, called Rotarix(TM), and is now planning to start Phase III safety and efficacy studies in 2001 after review with health authorities. Assuming product development and commercialization continues satisfactorily, SmithKline will pay us additional milestones and a royalty based on sales. CHOLERA VACCINE: We are developing a single dose, oral cholera vaccine using a live, genetically attenuated cholera strain. Based on this technology, developed in academia, we have developed the vaccine through early Phase II trials. We then negotiated a collaboration agreement under which a Phase IIb trial will be performed and funded by the Walter Reed Army Institute of Research ("WRAIR") and the National Institutes of Health (the "NIH"). This trial, set to begin in 2000, will test the safety, immunogenecity and protective capacity of the vaccine against a challenge with live virulent cholera. We will then determine our commercialization strategy with respect to the cholera vaccine based on clinical data from the trial. RESULTS OF OPERATIONS Three Month Period Ended March 31, 2000 as Compared With the Three Month Period Ended March 31, 1999 ------------------------------------------------------- AVANT reported consolidated net loss of $2,123,400, or $.04 per share, for the first quarter ended March 31, 2000, compared with a net loss of $2,741,800, or $.06 per share, for the first quarter ended March 31, 1999. The weighted average common shares outstanding used to calculate net loss per common share was 49,799,100 in 2000 and 42,526,300 in 1999. OPERATING REVENUE: Total operating revenue decreased $184,100, or 54.5%, to $153,800 for the first quarter of 2000 compared to $337,900 for the first quarter of 1999. This decrease is due primarily to timing differences in revenue recognition of option and license payments from Novartis between quarterly periods. During the first quarter of 1999, AVANT recognized revenue from a Novartis option payment which was amortized over the option term. During the first quarter of 2000, AVANT received a license payment from Novartis which is being recognized over the projected development period of the licensed field. 9

OPERATING EXPENSE: Total operating expense decreased $713,700, or 21.8%, to $2,557,000 for the first quarter of 2000 compared to $3,270,700 for the first quarter of 1999. The decrease in total operating expense is primarily due to the receipt of legal settlement payments and the reduction of goodwill amortization by $272,500 in the first quarter of 2000 compared with the same period last year. Research and development expense increased $18,500, or 1.0%, to $1,817,300 for the first quarter of 2000 compared to $1,798,800 for the first quarter of 1999. The increase in research and development expense is due to a increase in laboratory supplies and services expenses. General and administrative expense increased $40,300, or 3.8%, to $1,102,400 for the first quarter of 2000 compared to $1,062,100 for the first quarter of 1999. The increase is primarily attributed to increased general and patent legal expenses combined with increased corporate development and investor relations costs. During the quarter, we received legal settlement payments totaling $500,000 from the resolution of disputes arising from contractual arrangements. NON-OPERATING INCOME, NET: Non-operating income increased $88,800, or 46.5%, to $279,800 for the first quarter of 2000 compared to $191,000 for the first quarter of 1999. The increase is primarily due to an increase in interest income as a result of higher interest rates and higher average cash balances during the first quarter of 2000 compared to the first quarter of 1999. LIQUIDITY AND CAPITAL REOURCES AVANT ended the first quarter of 2000 with cash and cash equivalents of $18,761,600 compared to cash and cash equivalents of $13,619,000 at December 31, 1999. Cash provided by operations was $1,196,900 in the first quarter of 2000 compared to $2,382,400 used in operations in the first quarter of 1999. In July 1999, Novartis exercised its option to license TP10 for use in the field of transplantation. The decision to license TP10 resulted in a $6 million payment by Novartis which was received by AVANT in January 2000. The payment included an equity investment of $2,307,700 and a license fee of $3,692,300. Also, during the first quarter of 2000, AVANT raised approximately $1,305,200 and $244,500 in additional equity investment through the exercise of stock options and warrants, respectively. AVANT believes that cash inflows from existing collaborations, interest income on invested funds and our current cash and cash equivalents will be sufficient to meet estimated working capital requirements and fund operations beyond December 31, 2000 and into the first half of 2001. The working capital requirements of AVANT are dependent on several factors including, but not limited to, the costs associated with research and development programs, preclinical and clinical studies and the scope of collaborative arrangements. During 2000, we expect to take steps to raise additional capital including, but not limited to, licensing of technology programs with existing or new collaborative partners, possible business combinations, or issuance of common stock via private placement and public offering. YEAR 2000 THE STATEMENTS IN THIS SECTION INCLUDE THE "YEAR 2000 READINESS DISCLOSURE" WITHIN THE MEANING OF THE YEAR 2000 INFORMATION AND READINESS DISCLOSURE ACT. THIS SECTION CONTAINS CERTAIN STATEMENTS THAT ARE FORWARD-LOOKING STATEMENTS WITHIN THE MEANING OF SECTION 27A OF THE SECURITIES ACT OF 1933, AS AMENDED, AND SECTION 21E OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. AVANT'S YEAR 2000 READINESS, AND THE EVENTUAL AFFECTS OF THE YEAR 2000 ON AVANT MAY BE MATERIALLY DIFFERENT THAN CURRENTLY PROJECTED. THIS MAY BE DUE TO, AMONG OTHER THINGS, THE INABILITY OF AVANT OR OF KEY THIRD PARTIES WITH WHOM WE HAVE A SIGNIFICANT BUSINESS RELATIONSHIP TO ACHIEVE OR MAINTAIN YEAR 2000 READINESS. The "Year 2000" issue affects computer systems that have date sensitive programs that may not properly recognize the year 2000. Systems that do not properly recognize such information could generate data or cause a system to fail, resulting in business interruption. Through the first four months of the year 2000, 10

AVANT's operations are fully functioning and have not experienced any significant issues associated with the Year 2000 problem discussed above. Costs associated with modifications made by AVANT to be Year 2000 compliant were immaterial. There can be no assurance, however, that a failure by another company's system to be Year 2000 compliant would not have a material adverse affect on our business, operating results and financial condition. 11
