NOTE 1 —	Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting of only normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the six months ended June 30, 2006, are not necessarily indicative of the results that may be expected for the year ending December 31, 2006. For further information, refer to the financial statements and footnotes thereto included in the Company’s audited financial statements for the year ended December 31, 2005, as included elsewhere in the Form 8-K/A.

The Company’s principal activities, to date, have been in the research and development of diagnostics and drug treatments for cardiovascular diseases. The accompanying financial statements have been prepared in accordance with Statement of Financial Accounting Standard (SFAS) No. 7, “Development Stage Enterprises.”

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. The Company is currently a development stage enterprise and the Company’s continued existence is dependent upon its ability to obtain additional debt and/or equity financing. The Company has yet to generate a positive cash flow from operations, and until commercially viable products are developed and FDA approvals obtained, the Company is totally dependent upon debt and equity funding to finance the Company’s operations.

These factors raise substantial doubt about the Company’s continued existence as a going concern. In the event that the Company is unable to obtain additional debt or equity financing, the Company may have to cease or severely curtail its operations. This would materially impact its ability to continue as a going concern. There is no assurance that, if and when FDA clearance is obtained, the Company’s products will achieve market acceptance, or that the Company will ever achieve a profitable level of operations. The accompanying financial statements do not include any adjustments that might be necessary should the Company be unable to continue as a going concern. See Notes 6 and 7 — Consulting Agreement and Subsequent Event.

NOTE 2 —

Nature of Business

HaptoGuard Inc. was organized on November 4, 2003 under the laws of the State of Delaware with operations commencing on July 19, 2004 (inception). The Company is a development stage pharmaceutical company and was formed to research, acquire and further develop a combination of diagnostic therapeutic products that can be used to treat cardiovascular complications in patients with diabetes.

On September 28, 2004, the Company entered into an exclusive License and Supply Agreement with Oxis International Inc. The agreement provides the Company with the ability to license patented technologies related to a family of compounds to develop drugs for the treatment of cardiovascular diseases. On July 12, 2004, the Company entered into an exclusive License and Research Agreement with BioRap Technologies, Inc. The agreement provides the Company with the ability to license patented technologies to develop diagnostic techniques for cardiovascular diseases associated with diabetes.

These purchased technologies currently have no alternative use and there can be no assurance that the Company will ever obtain FDA approval, or that the Company will have the necessary funds to continue its research efforts. Significant additional costs will be required to fund clinical trials and seek the Food and Drug Administration (“FDA”) approval in order to commercially market any products.

NOTES TO CONDENSED FINANCIAL STATEMENTS — (Continued)

(Unaudited)

In the six months ended June 30, 2006, Dr. Berkowitz and the Noah Berkowitz Family Trust returned 500 shares of common stock to the Company and 1,282 shares of common stock were issued for $692,820 and 14 shares valued at $7,566 were issued for services rendered.


NOTE 3 —	Summary of Selected Significant Accounting Policies

In December 2004, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), “Share-Based Payment” (“SFAS 123R”), which replaces “Accounting for Stock-Based Compensation,” (“SFAS 123”) and supersedes Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees.” SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values effective for the Company January 1, 2006. Under SFAS 123R, the pro forma disclosures previously permitted under SFAS 123 are no longer an alternative to financial statement recognition.

The Company accounts for employee stock-based compensation, awards issued to non-employee directors, and stock options issued to consultants and contractors in accordance with SFAS 123R and Emerging Issues Task Force Issue No. 96-18, “Accounting for Equity Instruments that are Issued to Other Than Employees for Acquiring or in Conjunction with Selling Goods or Services.”

The Company has adopted the new standard, SFAS 123R, effective January 1, 2006 and has selected the Black-Scholes method of valuation for share-based compensation. The Company has adopted the modified prospective transition method which requires that compensation cost be recorded, as earned, for all unvested stock options and restricted stock outstanding at the beginning of the first quarter of adoption of SFAS 123R, and that such costs be recognized over the remaining service period after the adoption date based on the options’ original estimate of fair value.

Prior to adoption of SFAS 123R, the Company applied the intrinsic-value method under APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations, under which no compensation cost (excluding those options granted below fair market value) had been recognized. SFAS 123 established accounting and disclosure requirements using a fair-value based method of accounting for stock-based employee compensation plans. As permitted by SFAS 123, the Company elected to continue to apply the intrinsic-value based method of accounting described above, and adopted only the disclosure requirements of SFAS 123, as amended.

The following table summarizes relevant information as to reported results under the Company’s intrinsic value method of accounting for stock awards, with supplemental information as if the fair value recognition provisions of FAS 123 had been applied for the six months ended June 30, 2005 as follows:

Net loss, as reported	$	(976,880	)
Less: Total stock-based employee and director compensation expense determined under fair value method		(6,830	)

Pro forma net loss	$	(983,710	)

In January 2006, the Company issued 1,296 shares of common stock. Of these shares, 1,282 were issued for gross proceeds of $692,820 and 14 shares were issued as payment for services rendered in 2005 valued at $7,566.

The Company has a long-term incentive plan, the 2005 Employee, Director and Consultant Stock Plan, (the “2005 Plan”). The 2005 Plan was approved, and it is administered, by the Company’s Board of Directors. The 2005 Plan provides for the issuance of incentive stock options (“ISO”), non-qualified options, and stock grants up to a maximum of 1,518 shares of common stock. The options have a term of ten years, except for options granted to owners of more than 10% of all classes of the Company’s common stock, which have a maximum term of five years. The options under the 2005 Plan shall vest pursuant to the terms of the individual option agreements.

For the year ended December 31, 2005, the Company recognized $129,534 of expense related to the issuance of the options. A summary of the activity under stock option plan is as follows:

NOTE 6 —	Consulting Agreement

On April 4, 2006, the Company signed a consulting agreement to provide consulting services to Alteon Inc. for the clinical development of alagebrium and advancement of other intellectual property assets of Alteon. The Company signed a definitive merger agreement to be acquired by Alteon Inc. on April 19, 2006.

NOTE 7 —

Subsequent Event

On July 18, 2006, the Company’s shareholders approved the merger with Alteon, Inc., and on July 21, 2006, the companies’ combined operations in a stock transaction valued at approximately $8.8 million at the signing of the merger agreement on April 19, 2006. HaptoGuard and Alteon have complementary product platforms in cardiovascular diseases, diabetes and other inflammatory diseases, including two Phase 2 clinical-stage compounds focused on cardiovascular diseases in diabetic patients.

As part of the merger, a portion of existing shares of Alteon preferred stock held by Genentech, Inc. were converted into Alteon common stock. Genentech transferred a portion of the Alteon preferred stock that they held to HaptoGuard and canceled its remaining preferred stock position in Alteon. Genentech acquired the right of first negotiation for HaptoGuard’s cardiovascular compound, ALT-2074 (formerly BXT-51072), and future royalties on Alteon’s alagebrium.

The merger of the two companies was structured as an acquisition by Alteon. Under the terms of the merger agreement, HaptoGuard shareholders received a total of 37.4 million shares of Alteon common stock (from Alteon and Genentech, equal to approximately 31 percent of the shares of Alteon company stock outstanding after completion of the merger).

Key components of the transactions among HaptoGuard, Alteon and stockholder Genentech are as follows:

·	Alteon acquired all outstanding equity of HaptoGuard. In exchange, HaptoGuard shareholders received from Alteon approximately 22.5 million shares of Alteon common stock.
·	Genentech converted a portion of its existing Alteon preferred stock to Alteon common stock. A portion of Alteon preferred stock held by Genentech, which as of April 19, 2006 equaled approximately $3.5 million in Alteon common stock, was transferred to HaptoGuard shareholders.
·	The remaining Alteon preferred stock held by Genentech was cancelled.
·	Genentech will receive milestone payments and royalties on net sales of alagebrium, if any, and will receive a right of first negotiation on ALT-2074, HaptoGuard’s lead compound.

F-9

Following the merger, the new Alteon management team is as follows:

·	Noah Berkowitz, M.D., Ph.D. - President and Chief Executive Officer;
·	Malcolm MacNab, M.D., Ph.D. - Vice President, Clinical Development; and
·	Howard B. Haimes, Ph.D. - Executive Director, Preclinical Sciences.

Additionally, the Board of Directors of the combined company is composed of seven members as follows:

·	Kenneth I. Moch, Chairman - Director of Alteon since December 1998
·	Noah Berkowitz, M.D., Ph.D. - Director of HaptoGuard since November 2003
·	Marilyn G. Breslow - Director of Alteon since June 1988

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders

HaptoGuard Inc.

We have audited the accompanying balance sheets of HaptoGuard Inc. (a development stage company) (the “Company”) as of December 31, 2005 and 2004, and the related statements of operations, changes in stockholders’ equity (deficiency) and cash flows for the year ended December 31, 2005, for the period from July 19, 2004 (inception) to December 31, 2004 and for the period from July 19, 2004 (inception) to December 31, 2005. 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 auditing standards generally accepted in the United States of America. We also conducted our audit as of and for the year ended December 31, 2005, for the period July 19, 2004 (inception) to December 31, 2004, and for the period from July 19, 2004 (inception) to December 31, 2005 in accordance with the auditing standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, 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 HaptoGuard Inc. as of December 31, 2005 and 2004, and the results of its operations, and its cash flows for the year ended December 31, 2005, for the period from July 19, 2004 (inception) to December 31, 2004, and for the period from July 19, 2004 (inception) to December 31, 2005 in conformity with accounting principles generally accepted in the United States of America. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the financial statements, the Company has incurred a deficit accumulated during the development stage of $2,425,528 and cash flows used in operating activities of $1,906,913 during the development stage. These factors raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans regarding those matters are also described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

HAPTOGUARD INC.

NOTES TO FINANCIAL STATEMENTS (Audited)

NOTE 1 — Nature of Business

In January 2006, the Company issued shares of common stock, and is in negotiations to be acquired by another company as discussed in Note 8.

NOTE 2 — Basis of Presentation

NOTE 3 — Summary of Significant Accounting Policies

Cash and Cash Equivalents

The Company considers all highly liquid short-term investments with original maturities of three months or less to be cash equivalents. Cash and cash equivalents consist of cash and money market instruments on deposit with a financial institution. At times, such cash balances may be in excess of federally insured limits.

F-16

HAPTOGUARD INC.

(A Development Stage Company)

NOTES TO FINANCIAL STATEMENTS — (Continued)

Property and Equipment

Property and equipment are stated at cost. Maintenance and repairs are charged to expense as incurred; costs of major additions and betterments are capitalized. When property and equipment is sold or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in income.

Depreciation Expense

Depreciation is provided for using the straight-line method over the estimated useful lives of the related assets.

Research and Development Expenses

In accordance with Statement of Financial Accounting Standard (SFAS) No. 2, “Research and Development Expenses”, such costs are expensed as incurred. Research and development expenses consist of outside services for research and development activities associated with product development. During 2004, the Company entered into two license arrangements (Note 1) to purchase the exclusive patent rights to certain technology for developing diagnosis and treatment of cardiovascular diseases. The Company, upon entering into these agreements, paid $500,000 for the use of these rights. The terms of the licenses extend through the expiration dates of the various underlying patents, with certain exceptions and diligence milestones, as defined in the respective agreements. The patents contain expiration dates which extend through March 2023. In November 2005, the Company was notified by Oxis International Inc. that it risked forfeiting its rights to the licensed technology as a result of the Company not initiating a clinical trial by the date set forth in the Licensing Agreement.

In December 2005, the Company paid Oxis International Inc. $100,000 as stipulated in the Licensing Agreement to extend the deadline of its diligence milestones by six months.

In accordance with SFAS No. 2, the cost to purchase these research and development rights are required to be charged as an expense since there is currently no alternative future use for this technology and, therefore, no separate economic value.

Reclassifications

Certain amounts in the financial statements for the prior period have been reclassified to be in conformity with the current year presentation. The reclassifications had no effect on the previously reported net loss.

Income Taxes

The Company accounts for income taxes under Statement of Financial Accounting Standard (SFAS) No. 109, “Accounting for Income Taxes”. SFAS No. 109 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statements and tax basis of assets and liabilities, and for the expected future tax benefit to be derived primarily from tax loss carry forwards. As of December 31, 2005, the Company has approximately $2,400,000 of federal net operating losses available to offset future taxable income, which, if not utilized, will begin to expire in 2024. The Company has recorded a full valuation allowance against its deferred tax assets since management believes that based upon current available objective evidence it is more likely than not that the deferred tax asset will not be realized The Company’s effective tax rate differs from the federal statutory rate as a result of the change in the valuation allowance:

F-17

HAPTOGUARD INC.

(A Development Stage Company)

NOTES TO FINANCIAL STATEMENTS — (Continued)

	The change in the valuation allowance for deferred tax assets are summarized as follows:

			Period from
			July 19, 2004
	Year Ended		(Inception) to
	December 31,		December 31,
	2005		2004

Beginning balance	$	308,000	$	—
Change in allowance		662,000		308,000
Ending balance	$	970,000	$	308,000

As of December 31, 2005 and 2004, the Company has net operating loss carryforwards of $2,400,000 and $700,000, respectively, available to offset future taxable income. These carryforwards will expire at various dates through 2025. Internal Revenue Code Section 382 rules limit the utilization of net operating losses upon a change of control of a company. The Company has not performed an evaluation whether a change of control has taken place and as such, utilization of its net operating losses may be subject to substantial limitation in future periods.

No provision for income taxes has been recorded in the financial statements as a result of such operating losses as for the year ended December 31, 2005 and the period from July 19, 2004 (inception) to December 31, 2004.

Management Estimates

The preparation of financial statements are in conformity with accounting principles generally accepted in the United States and requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Fair Value of Financial Instruments

The recorded amounts of cash and cash equivalents, accounts payable, accrued expenses and deposits for common stock purchases as presented in the financial statements approximate fair value because of the short-term nature of these instruments.

Stock-Based Compensation

As permitted by FASB Statement No. 123, “Accounting for Stock-Based Compensation” (“FAS 123”), which establishes a fair value based method of accounting for equity-based compensation plans, the Company has elected to follow Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”), for recognizing equity-based compensation expense for financial statement purposes. Under APB 25, no compensation expense is recognized at the time of option grant if the exercise price of the employee stock option is fixed and equal or exceeds the fair value of the underlying common stock on the date of grant and the number of shares to be issued pursuant to the exercise of such options are known and fixed at the grant date.

The Company accounts for equity instruments issued to non-employees in accordance with the provisions of FAS 123 and the Emerging Issues Task Force in Issue No. 96-18, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or In Conjunction with Selling, Goods or Services which require that such equity instruments are recorded at their fair value on the measurement date, which is typically the date the services are performed.

HAPTOGUARD INC.

NOTES TO FINANCIAL STATEMENTS — (Continued)

In December 2002, the FASB issued Statement No. 148, Accounting for Stock-Based Compensation-Transaction and Disclosure (“FAS 148”). This standard amends the disclosure requirements of FAS 123 for fiscal years ending after December 15, 2002 to require prominent disclosure in both annual and interim financial statements about the method used and the impact on reported results. The Company follows the disclosure-only provisions of FAS 123 which requires disclosure of the pro forma effects on net income (loss) as if the fair value method of accounting prescribed by FAS 123 had been adopted, as well as certain other information.

Option valuation models require the input of highly subjective assumptions including the expected life of the option. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options.

Recently Issued Accounting Standards

In January 2003, Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 46, “Consolidation of Variable Interest Entities” (“FIN 46”). This interpretation of Accounting Research Bulletin No. 51, “Consolidated Financial Statements”, provides guidance for identifying a controlling interest in a variable interest entity (“VIE”) established by means other than voting interest. FIN 46 also required consolidation of a VIE by an enterprise that holds such controlling interest. In December 2003, the FASB completed its deliberations regarding the proposed modifications to FIN No., 46 and issued Interpretation Number 46R, “Consolidation of Variable Interest Entities — an Interpretation of ARB 51” (“FIN No. 46R”). The decisions reached included a deferral of the effective date and provisions for additional scope exceptions for certain types of variable interests. Application of FIN No. 46R is required in financial statements of public entities that have interests in VIEs, or potential VIEs, commonly referred to as special-purpose entities for periods ending after December 15, 2003. Application by public small business issuers’ entities is required in all interim and annual financial statements for periods ending after December 15, 2004. The adoption of this pronouncement did not have a material effect on the Company’s financial statements.

HAPTOGUARD INC.

(A Development Stage Company)

NOTES TO FINANCIAL STATEMENTS — (Continued)

In December 2004, the FASB issued Statement of Financial Accounting Standard (“SFAS”) No. 123R, “Share Based Payment”. This statement is a revision of SFAS Statement No. 123, “Accounting for Stock-Based Compensation” and supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees”, and its related implementation guidance. SFAS 123R addresses all forms of share based payment (“SBP”) awards including shares issued under employee stock purchase plans, stock options, restricted stock and stock appreciation rights. Under SFAS 123R, SBP awards result in a cost that will be measured at fair value on the awards’ grant date, based on the estimated number of awards that are expected to vest.

This statement is effective for public entities that file as small business issuers — as of the beginning of the first interim or annual reporting period that begins after December 15, 2005. The adoption of this pronouncement is not expected to have a material effect on the Company’s financial statements.

In December 2004, the FASB issued Statement of Financial Accounting Standard (“SFAS”) No. 153, “Exchanges of Nonmonetary Assets”. This Statement amends Opinion 29 to eliminate the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. A nonmonetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange. The provisions of this Statement are effective for nonmonetary asset exchanges occurring in fiscal periods beginning after June 15, 2005. Earlier application is permitted for nonmonetary asset exchanges occurring in fiscal periods beginning after December 16, 2004. The provisions of this Statement should be applied prospectively. The adoption of this pronouncement is not expected to have a material effect on the Company’s financial statements.

Emerging Issue Task Force (EITF) Issue 04-8, “The Effect of Contingently Convertible Instruments on Diluted Earnings per Share.” The EITF reached a consensus that contingently convertible instruments, such as contingently convertible debt, contingently convertible preferred stock, and other such securities, should be included in diluted earnings per share (if dilutive) regardless of whether the market price trigger has been met. The consensus is effective for reporting periods ending after December 15, 2004. The adoption of this pronouncement did not have a material effect on the Company’s financial statements.

In June 2005, the FASB issued SFAS No. 154, “Accounting Changes and Errors Corrections, a replacement of APB Opinion No. 20 and SFAS No. 3.” This statement applies to all voluntary changes in accounting principle, and changes the requirements for accounting for and reporting of a change in accounting principle. SFAS No. 154 requires retrospective application to prior periods’ financial statements of a voluntary change in accounting principle unless it is impractical. APB opinion No. 20 previously required that most voluntary changes in accounting principle to be recognized by including in net income of the period of the change the cumulative effect of changing to the new accounting principle. SFAS No. 154 improves the financial reporting because its requirements enhance the consistency of the financial reporting between periods. The adoption of this pronouncement did not have a material effect on the Company’s financial statements.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

(1) Description of Transaction and Basis of Presentation

On April 19, 2006, Alteon entered into a definitive merger agreement with HaptoGuard, Inc., Genentech, Inc. and Alteon Merger Sub, Inc., a wholly-owned subsidiary of Alteon. Under the terms of the merger agreement provides that upon the terms and subject to the conditions set forth in the merger agreement, the Merger Sub merged with and into HaptoGuard, and HaptoGuard became the surviving corporation and a wholly-owned subsidiary of Alteon.

At the effective time of the merger, (a) pursuant to the terms of Alteon’s certificate of incorporation and the merger agreement, Genentech converted a portion of Alteon’s preferred stock that it holds into shares of Alteon’s common stock, such that the number of such shares of common stock issued were, when added to the shares of common stock already owned by Genentech, equal to 19.99% of Alteon’s outstanding common stock as calculated after the conversion of the preferred stock; (b) Genentech transferred to HaptoGuard a portion of Alteon preferred stock held by it, in such an amount that converted to a number of shares of Alteon common stock, in accordance with the terms of Alteon’s certificate of incorporation and the terms of the merger agreement equal in value to $3,500,000 (the price per share of Alteon common stock based on the volume-weighted average price of the per share selling prices on the American Stock Exchange for the twenty (20) trading days immediately preceding the signing of the merger agreement); (c) Genentech transferred to Alteon all of the remaining shares of Alteon preferred stock held by Genentech which were not either converted or transferred, and such shares of preferred stock ceased to be outstanding, were canceled and retired without payment of any consideration therefor other than pursuant to the terms of the merger agreement and ceased to exist; (d) every share of HaptoGuard common stock issued and outstanding immediately prior to the effective time of the merger (other than the dissenting shares) were converted into the right to receive a number of shares of Alteon common stock equal to the quotient of (i) the sum of (x) a number of shares of Alteon common stock issued by Alteon to HaptoGuard stockholders at the effective time with a value of $5.3 million, plus (y) the number of shares of Alteon common stock issued pursuant to section (b) above at the effective time, the market value of (x) and (y) to be equal to $8,800,000, divided by (ii) the sum of (x) the number of outstanding shares of HaptoGuard common stock at the effective time, and (y) the number of Share Equivalents (as defined below) (the “Exchange Ratio”); and (e) each share of HaptoGuard common stock held in the treasury of HaptoGuard and each share of HaptoGuard common stock owned by Alteon or by any direct or indirect wholly-owned subsidiary of HaptoGuard or Alteon immediately prior to the effective time did, by virtue of the merger and without any action on the part of the holder thereof, cease to be outstanding, were canceled and retired without payment of any consideration therefor other than pursuant to the terms of the merger agreement and ceased to exist. Alteon assumed each outstanding vested or unvested option to purchase HaptoGuard common stock, which are exercisable following the merger for the number of shares of HaptoGuard common stock that were purchasable under such option immediately prior to the effective time of the merger multiplied by the Exchange Ratio (rounded down to the nearest whole number of shares of common stock) and the per share exercise price for the shares of HaptoGuard common stock issuable upon exercise of such assumed option is equal to the quotient determined by dividing the exercise price per share of HaptoGuard common stock at which such option was exercisable immediately prior to the effective time of the merger by the Exchange Ratio (and rounding the resulting exercise price up to the nearest whole cent). All outstanding warrants to purchase HaptoGuard common stock were exchanged for the right to receive a number of shares of Alteon common stock (“Share Equivalents”) at the effective time of the merger which had a market value equal to the difference between (i) the market value of the product of the number of shares of HaptoGuard common stock that were purchasable under such warrants immediately prior to the Effective Time multiplied by the Exchange Ratio (rounded down to the nearest whole number of shares of Alteon common stock) and (ii) the total exercise price of such warrant.

The merger will be accounted for as a purchase by Alteon under accounting principles generally accepted in the United States of America. Under the purchase method of accounting, the net liabilities of HaptoGuard will be recorded as of the acquisition date, at their respective fair values, and combined with those of Alteon. The reported financial condition and results of operations of Alteon will reflect these values, but will not be restated retroactively to reflect the historical financial position or results of operations of HaptoGuard.

As required by FASB Interpretation No. 4, “Applicability of FASB Statement No. 2 to Business Combinations Accounted for by the Purchase Method”, the Company will record a charge upon the closing of the transaction of approximately $11,377,000 for the estimated portion of the purchase price allocated to acquired IPRD (in-process research and development).

A valuation using the guidance in SFAS NO. 141, “Business Combinations” and the AICPA Practice Aid “Assets Acquired in a Business Combination to Be Used in Research and Development Activities: A Focus on Software, Electronic Devices and Pharmaceutical Industries” was performed to determine the fair value of research and development projects of HaptoGuard which were in-process but not yet completed.

(2) To eliminate the stockholders’ deficiency accounts of HaptoGuard.

(3) To reflect the issuance of 37,399,065 shares of common stock to HaptoGuard shareholders, including 22,524,437 shares from Alteon and 14,874,628 shares from the conversion of Genentech’s preferred stock ownership in Alteon. The number of shares was calculated by dividing the preliminary purchase price of $8,800,000 by the 20-day volume weighted average market price of the stock or $0.2353.

The components of the preliminary purchase price, which we anticipate will be charged to IPRD, are summarized as follows (000’s):


Common stock issued	$	8,800
Fair value of HaptoGuard vested options		235
Estimated transaction costs		1,757
		10,792
Net liabilities assumed		585
Total purchase price	$	11,377

(4) To reflect estimated transaction fees incurred in connection with the merger.

(5) To reflect the fair value of vested HaptoGuard stock options exchanged for Alteon options.

(6) To eliminate fees paid by Alteon to HaptoGuard.

(7) To reflect the partial conversion and cancellation of all outstanding preferred stock to Genentech in exchange for 13,492,349 shares of common stock and certain rights and royalties as noted in the definitive merger agreement.

(8) To eliminate advance to HaptoGuard.

(9) To reflect required payments of severance and insurance costs incurred as a direct result of the merger.
