As of January 11, 2001, Inhale has received valid acceptances (the "Offer Acceptances") from the holders of 1,946,939 shares in the aggregate, representing approximately 95%, of the existing issued ordinary share capital of Bradford. Inhale acquired the issued share capital of Bradford for approximately 3.75 million in newly issued shares of Inhale common stock and approximately $20.0 million in cash. For each share of Bradford common stock Inhale will issue 1.8354 new shares of Inhale common stock and pay approximately $9.80 in cash.

F-30 Report of Independent Auditors The Board of Directors and Shareholders Bradford Particle Design plc We have audited the accompanying balance sheets of Bradford Particle Design plc as of May 31, 2000 and 1999, and the related profit and loss account, cash flow statement, statement of total recognized gains and losses and movements in shareholders' funds for each of the years in the two-year period ended May 31, 2000. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these combined financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United Kingdom that are substantially equivalent to auditing standards generally accepted in the 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. 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 the Company as of May 31, 2000 and 1999, and the results of their operations and their cash flows for each of the years in the two-year period ended May 31, 2000, in conformity with generally accepted accounting principles in the United Kingdom. Accounting principles generally accepted in the United Kingdom vary in certain significant respects from accounting principles generally accepted in the United States. A description of the significant differences between the two accounting standards, including presentation differences, that are applicable to the Company are summarized in Note 21 to the financial statements. /s/ Ernst & Young LLP Palo Alto, California January 5, 2001 F-1 Bradford Particle Design plc (formerly Bradford Particle Design Limited) Profit and Loss Account YEARS ENDED MAY 31 -------------------------------- NOTE 2000 1999 ---------------------------------------------- (pound) (pound) Turnover 2 615,420 1,305,780 Other operating income 3 36,673 96,614 Raw materials and consumables (137,131) (94,126) Staff costs: Wages and salaries (748,829) (434,056) Social security costs (68,861) (38,424) Other pension costs (99,805) (60,476) Depreciation (168,606) (165,506) Other operating charges (639,143) (520,621) -------------------------------- Operating (loss) profit 4 (1,210,282) 89,185 Interest receivable and similar income 7 4,358 5,670 Interest payable and similar charges 7 (13,209) -- -------------------------------- (Loss) profit on ordinary activities before taxation (1,219,133) 94,855 Tax on (loss) profit on ordinary activities 8 88,979 (22,984) -------------------------------- Retained (loss) profit for the financial year 15 (1,130,154) 71,871 ================================ There were no recognized gains or losses other than the (loss) profit for the year.

The carrying value of tangible fixed assets are reviewed for impairment in periods if events or changes in circumstances indicate the carrying amount may not be recoverable.

F-16 Bradford Particle Design plc (formerly Bradford Particle Design Limited) Notes to Financial Statements (continued) 21. UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES The financial statements of the Company have been prepared in accordance with United Kingdom generally accepted accounting principles (UK GAAP) which differ in certain significant respects from United States generally accepted accounting principles (US GAAP). A description of the significant differences between UK GAAP and US GAAP, including presentation differences, that are applicable to the Company is set out below: REVENUE RECOGNITION UK GAAP requires that revenue be recognized based on an assessment of the substance of a transaction and whether the transaction has given rise to new assets or liabilities for the reporting entity or has changed the entity's existing assets or liabilities. Where a transaction incorporates one or more options, guarantees or conditional provisions, their commercial effect should be assessed in the context of all the aspects and implications of the transaction, including assessment of the inherent risks and the likelihood of those risks having a commercial effect in practice, in order to determine what assets and liabilities arise from the transaction. Furthermore, in order to recognize assets/liabilities arising from a transaction there must be sufficient evidence of the existence of these items and their monetary amount must be measurable with sufficient reliability. US GAAP, as interpreted by the U.S. Securities and Exchange Commission ("SEC") under Staff Accounting Bulletin ("SAB") No. 101, has specific revenue recognition criteria that apply to nonrefundable upfront license fees and certain guaranteed payments associated with multiyear collaborations. In particular, when the Company has continuing involvement with the customer, up-front, nonrefundable fees and certain other payments are earned over the period of the continued involvement. This period of continuing involvement represents the culmination of the earnings process. Prior to the SEC's issuance of Staff Accounting Bulletin 101, UK GAAP revenue recognition practices for up-front, nonrefundable technology fees were similar to US GAAP. SAB 101 is effective for companies no later than the fourth fiscal quarter of fiscal years beginning after December 15, 1999, and therefore, no adjustments were required for the period under audit in order to reconcile to US GAAP. F-17 Bradford Particle Design plc (formerly Bradford Particle Design Limited) Notes to Financial Statements (continued) 21. UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES (CONTINUED) CASH FLOWS The Cash Flow Statement is prepared in accordance with Financial Reporting Standard No. 1 (revised) `Cash Flow Statements' ("FRS 1"). Its objectives and principles are similar to those set out in SFAS 95. The principal difference between the standards relates to classification. Under FRS 1, the Company presents its cash flows for: (a) operating activities; (b) exceptional non-operating items; (c) dividends from associated undertakings; (d) returns on investments and servicing of finance; (e) taxation; (f) capital expenditure and financial investment; (g) acquisition and disposals; (h) equity dividend paid; and (i) financing. SFAS 95 requires only three categories of cash flow activity:(a) operating; (b) investing; and (c) financing. Cash flows from exceptional non-operating items, returns on investments and servicing of finance, and taxation shown under FRS 1 would be included as operating activities under SFAS 95. Changes in overdrafts are included within cash equivalents under FRS 1 and would be considered a financing activity under SFAS 95. Under US GAAP, capital expenditure and financial investment and acquisitions and disposals are reported within investing activities. DEFERRED TAXATION UK GAAP requires that no provision for deferred taxation should be recorded if there is reasonable evidence that such taxation will not be payable in the foreseeable future. Deferred tax assets are only recognized when they are expected to be recoverable without replacement by equivalent deferred tax assets. US GAAP requires full provision of deferred taxation liabilities and permits deferred tax assets to be recognized if their realization is considered to be more likely than not. There are no differences in respect of the amounts of deferred taxation recorded in the financial statements because the Company has net deferred tax assets and considers that it is more likely than not that they will not be recovered. STATEMENT OF COMPREHENSIVE INCOME Under UK GAAP, the Company presents a statement of Profit and Loss Account, which is equivalent to a Statement of Comprehensive Income under US GAAP. F-18 Bradford Particle Design plc (formerly Bradford Particle Design Limited) Notes to Financial Statements (continued) 21. UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES (CONTINUED) PROSPECTIVE ACCOUNTING CHANGES In June 1998, the FASB issued Statement of Financial Accounting Standards, ("SFAS") No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. SFAS No. 133 establishes accounting and reporting standards for derivative financial instruments and hedging activities related to those instruments, as well as other hedging activities. Because the Company does not currently hold any derivative instruments and does not engage in hedging activities, SFAS No. 133 would not create significant differences between its financial position, results of operations or cash flows prepared on UK GAAP and US GAAP bases. SFAS No. 133 is effective for fiscal years beginning after June 15, 2000. In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin ("SAB") 101, REVENUE RECOGNITION IN FINANCIAL STATEMENTS, which provides guidance related to revenue recognition based on interpretations and practices followed by the SEC. SAB 101 was effective the first fiscal quarter of fiscal years beginning after December 15, 1999 and requires companies to report any changes in revenue recognition as cumulative change in accounting principle at the time of implementation in accordance with Accounting Principles Board Opinion 20, "ACCOUNTING CHANGES." In March 2000, the SEC issued SAB 101A, "AMENDMENT: REVENUE RECOGNITION IN FINANCIAL STATEMENTS," and in June 2000, the SEC issued SAB 101B, "SECOND AMENDMENT: REVENUE RECOGNITION IN FINANCIAL STATEMENTS," which delay the implementation. SAB 101, as modified, is effective for companies no later than the fourth fiscal quarter of fiscal years beginning after December 15, 1999. Upon adoption of the SAB interpretation, management expects the cumulative effect on shareholders' funds would be a net decrease of approximately (pound)690,000 as of May 31, 2000. F-19 Bradford Particle Design plc (formerly Bradford Particle Design Limited) Notes to Financial Statements (continued) 21. UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES (CONTINUED) PROSPECTIVE ACCOUNTING CHANGES (CONTINUED) In March 2000, the FASB issued Interpretation No. 44, ("FIN 44"), ACCOUNTING FOR CERTAIN TRANSACTIONS INVOLVING STOCK COMPENSATION - AN INTERPRETATION OF APB 25. This Interpretation clarifies (a) the definition of employee for purposes of applying Opinion 25, (b) the criteria for determining whether a plan qualifies as a non compensatory plan, (c) the accounting consequence of various modifications to the terms of a previously fixed stock option or award, and (d) the accounting for an exchange of stock compensation awards in a business combination. This Interpretation is effective July 1, 2000, but certain conclusions in this Interpretation cover specific events that occur after either December 15, 1998, or January 12, 2000. To the extent that this Interpretation covers events occurring during the period after December 15, 1998, or January 12, 2000, but before the effective date of July 1, 2000, the effects of applying this Interpretation are recognized on a prospective basis from July 1, 2000. The Company currently issues stock to employees at the deemed fair market value and does not give stock options to nonemployees. As such, the Company expects that FIN 44 would not create significant differences between its financial position, results of operations or cash flows prepared on UK GAAP and US GAAP bases. The Company does not believe that the effect of the adoption of FRS 16 "Current Taxation" for UK GAAP purposes in the year ending May 31, 2001 will be material.

ACCOUNTING POLICIES The profit and loss account and balance sheet for the half-year periods ended November 30, 2000 and 1999 have been prepared on a basis consistent with the accounting policies disclosed in the audited financial statements of Bradford Particle Design plc for the two years ended May 31, 2000. 2. UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES The financial statements have been prepared in accordance with United Kingdom generally accepted accounting principles (UK GAAP) which differ in certain significant respects from generally accepted accounting principles in the United States of America (US GAAP). A description of the significant differences between UK GAAP and US GAAP, including presentation differences, that are applicable to the Company, is set out in the financial statements for the two years ended May 31, 2000. 3. STATUS OF UNAUDITED FINANCIAL STATEMENTS FOR THE SIX-MONTH PERIOD ENDED NOVEMBER 30, 2000 The financial information included in these half-year unaudited financial statements does not comprise statutory financial statements within the meaning of Section 240 of the United Kingdom Companies act 1985. 4. PROSPECTIVE ACCOUNTING CHANGES A description of the prospective US GAAP accounting changes is set out in the financial statements for the two years ended May 31, 2000. Upon adoption of the SAB 101 revenue recognition interpretations, the six-month period ended November 30, 2000, total revenue would decrease approximately (pound)2,235,000 and the cumulative effect on shareholders' funds would be a net decrease of approximately (pound)2,925,000. All other prospective accounting pronouncements described in the May 31, 2000 audited financial statements would not have a significant effect on the results of operations or the financial position of the Company. F-24 INHALE THERAPEUTIC SYSTEMS, INC. UNAUDITED PRO FORMA CONDENSED COMBINED FINANICAL INFORMATION The following unaudited pro forma condensed combined financial statements give effect to the acquisition by Inhale Therapeutic Systems, Inc. ("Inhale") of the entire issued share capital of Bradford Particle Design plc ("Bradford"). The unaudited pro forma condensed combined financial information including the accompanying notes, have been derived from the historical financial statements of Inhale, are based on and qualified in their entirety by reference to, and should be read in conjunction with, the reported audited consolidated financial statements and the accompanying notes of Inhale and Bradford. The unaudited pro forma condensed combined balance sheet as of September 30, 2000, has been prepared assuming the acquisition had been consummated as of that date. The unaudited pro forma condensed combined statements of operations are provided for the year ended December 31, 1999 and the nine months ended September 30, 2000, including the amortization of goodwill and other intangible assets, giving effect to the acquisition as though it had occurred as of January 1, 1999. The acquisition of Bradford has been accounted for using the purchase method of accounting and, accordingly, the purchase price has been allocated to the assets purchased and the liabilities assumed based on fair values at the date of acquisition. The allocation of the aggregate purchase price for the acquisition, together with the liabilities assumed pursuant thereto, to the net assets acquired has been based on management's preliminary estimate. Adjustments to asset values and liabilities in the final allocation may differ from these estimates, which could impact future earnings. Inhale Therapeutic Systems, Inc.'s historical condensed financial information included in these pro forma financial statements is derived from its September 30, 2000 unaudited consolidated financial statements included in its Form 10-Q for the same period, and from its December 31, 1999 audited consolidated financial statements included in its most recent Form 10-K/A. Bradford's financial information included in these pro forma financial statements is derived from its nine months ended August 31, 2000 unaudited financial statements, and from its twelve months ended November 30, 1999 unaudited financial statements. Bradford's financial statements included in the pro forma information as of all dates and for all periods presented have been adjusted, where appropriate, to present Bradford's financial position and results of operations in accordance with generally accepted accounting principles in the United States. These adjustments are more fully described in Bradford's November 30, 2000 unaudited financial statements, and in its May 31, 2000 audited financial statements, which are included as exhibits to this filing. F-25 The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and is not necessarily indicative of the operating results or financial positions that would have occurred if the transaction had been consummated at the dates indicated, nor is it necessarily indicative of future operating results or financial position of the combined companies and should not be construed as respresentative of these amounts for any future dates or periods.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION On December 21, 2000, Inhale Therapeutic Systems, Inc. ("Inhale") announced an offer to purchase all of the outstanding shares of Bradford Particle Design plc ("Bradford") an unquoted British company for cash and stock valued at approximately $200 million in a purchase business combination (the "Agreement"). On January 8, 2000, Inhale received irrevocable undertakings from 95% of Bradford's shareholders to accept the offer. Pursuant to the Agreement, Inhale issued 3,752,406 shares of its common stock and $20.0 million in cash in exchange for 100% of the outstanding shares of Bradford's common stock, including outstanding stock options. At closing, all outstanding stock options of Bradford were fully vested. Inhale's total cost to acquire Bradford is estimated to be $187.2 million based on an average price of $42 per share of Inhale's common stock. The stock price used for the pro forma presentation is based on an average price from receipt of unconditional acceptances of the offer. The actual book value used to record the transaction may differ from these preliminary estimates. Bradford's financial statements included in the pro forma financial information as of all dates and for all periods presented have been adjusted, where appropriate, to present Bradford's financial position and results of operations in accordance with generally accepted accounting principles in the United States. Included in these adjustments is the assumed conversion of the functional currency from UK Pound Sterling to U.S. dollars. The assumed conversion rates used at August 31, 2000, for the twelve-month period ended November 30, 1999 and for the nine-month period ended August 31, 2000 were $1.4550, $1.5927, and $1.4550 per (pound)1.00, respectively. The cost to acquire Bradford has been allocated to the assets acquired and liabilities assumed according to their respective fair values, with the excess purchase price being allocated to goodwill. The allocation of the aggregate purchase price is based on management's preliminary estimate. A formal valuation analysis for purposes of allocating the fair value of purchased assets and liabilities has not been completed. As such, adjustments to asset values and liabilities in the final allocation may differ significantly from these estimates, which could impact future earnings. F-30 INHALE THERAPEUTIC SYSTEMS, INC.

Inhale will amortize the value assigned to customer relationships on a straight-line basis over an average estimated life of 5 years. The acquired trademark is recognized for the intrinsic value of Bradford's name and products in the market place. Inhale will amortize the value assigned on a straight-line basis over an average estimated life of 5 years. Goodwill, which represents the excess of the purchased price of an investment in an acquired business over the fair value of the underlying net identifiable asset, will be amortized on a straight-line basis over its estimated remaining useful life.
