Savings Plan We have audited the accompanying statements of net assets available for benefits of the Penwest Pharmaceuticals Co. Savings Plan as of December 31, 2002 and 2001, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan'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. 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 net assets available for benefits of the Plan at December 31, 2002 and 2001, and the changes in its net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2002, is presented for purposes of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole. /s/ Ernst & Young LLP Stamford, Connecticut June 23, 2003 1 Penwest Pharmaceuticals Co.

Savings Plan Notes to Financial Statements 1. DESCRIPTION OF THE PLAN The following description of the Penwest Pharmaceuticals Co. (the "Company" or the "Employer") Savings Plan (the "Plan") provides only general information. Participants should refer to the Summary Plan Description for a more complete description of the Plan's provisions. Copies are available from the Plan's Administrative Committee. Effective January 1, 2002, the Plan changed its service providers from Frank Russell Trust Company to CIGNA Retirement & Investment Services. In anticipation of the transfer of the Plan's assets to the new service provider, all equity investments of the Plan, except for the Penwest Pharmaceuticals Co. common stock were liquidated as of December 31, 2001. Therefore, at December 31, 2001, Plan investments consisted of Penwest Pharmaceuticals Co. common stock, short term investments and participant loans. The open trade receivables of $2,245,205 at December 31, 2001, presented in the Statements of Net Assets Available for Benefits, represents the proceeds from the liquidated investments which did not settle until January 2002. GENERAL The Plan is a defined contribution plan covering all U.S. employees of the Company, including part-time employees. An employee is eligible to participate in the Plan after attaining age 18 and completing three months of service, as defined in the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"), as amended. CONTRIBUTIONS Participants may contribute from 1% up to 12% of pre-tax compensation as defined in the Plan agreement. The Company may make quarterly employer matching contributions as defined in the Plan agreement, in an amount equal to a percentage of each participant's pre-tax contributions to the Plan up to 6% of earnings. Additional amounts may be contributed at the discretion of the Company's Board of Directors to be allocated to the accounts of the participants who are employed on the last day of the Plan Year. PARTICIPANT ACCOUNTS Individual accounts are maintained for all Plan participants. These accounts reflect participants' contributions and related Company matching and discretionary contributions, if any, to the Plan and allocations of earnings or losses on the Plan's investments. Allocations are based on participant account balances. As of the end of each Plan year, forfeitures of nonvested amounts are first used to restore any forfeitures for returning employees who previously worked for the Company within a five year period, and any remaining amounts are used to reduce subsequent employer contributions. 4 Penwest Pharmaceuticals Co. Savings Plan Notes to Financial Statements (continued) 1. DESCRIPTION OF THE PLAN (CONTINUED) VESTING Participants are immediately vested in their contributions, as well as any earnings thereon. Vesting in the Employer contribution portion of their accounts, as well as any earnings thereon is based on years of credited service and vest in accordance with the following schedule: CREDITED SERVICE % VESTED - ------------------ -------- Less than one year 0% One year 25% Two years 50% Three years 75% Four years or more 100% In the event of disability, attainment of age 65, or death of a participant, the related Employer contributions and earnings thereon become fully vested. INVESTMENT OPTIONS All of the Plan's investment programs are fully participant directed. Upon enrollment in the Plan, a participant may direct Employer and participant contributions among any of the Plan's current investment options. The Penford Corporation stock fund included account balances transferred from the Penford Plan in connection with the Company's former parent, Penford Corporation's distribution to its shareholders of all of the shares of the Company's common stock effective September 1, 1998. The Plan did not permit additional investments to be made by participants into the Penford Corporation stock fund. In November 2001, in anticipation of the change of the Plan's service providers (see Note 1), the Plan's Administrative Committee made the decision to liquidate the Penford Corporation stock fund. All remaining shares of Penford Corporation common stock held by the Plan were sold in December 2001. PAYMENT OF BENEFITS Upon termination, permanent disability, or death, 100% of the value of the participant's vested account may be paid to the participant or the participant's beneficiary in a lump sum payment. PARTICIPANT LOANS Participants may, in the event of financial hardship as defined in the Plan, borrow from their fund accounts a minimum of $1,000 up to a maximum of $50,000 or 50% of their vested account balance, whichever is less. Loans bear interest at a rate determined by the Plan's Administrative Committee. 5 Penwest Pharmaceuticals Co. Savings Plan Notes to Financial Statements (continued) 1. DESCRIPTION OF THE PLAN (CONTINUED) PARTICIPANT LOANS (CONTINUED) Interest rates on outstanding loans as of December 31, 2002 and 2001 range from 5.0% to 9.5%. Loan terms generally range from 1 to 5 years but may be increased if the loan is used for the purchase of a primary residence. The loans are secured by the balance in the participant's account. EXPENSES In 2001, prior to the change in service provider (Note 1), the Plan paid investment management, transaction-related and recordkeeping expenses, and the Company paid all other expenses of the Plan. Effective January 1, 2002, the investment management expenses are charged to the Plan's underlying investment funds and the Plan paid transaction and account-based expenses. The Company paid all other expenses of the Plan, including administration, recordkeeping and trust service charges. PLAN TERMINATION Although the Company has not expressed any intent to do so, it has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts. 2. SUMMARY OF ACCOUNTING POLICIES INVESTMENT VALUATION The Plan's investments are stated at fair value. Mutual funds are valued at quoted market prices which represent the net asset values of shares held by the Plan at year-end. Penwest Pharmaceuticals Co. common stock is valued at the last reported sales price on the last business day of the year. The participant loans are valued at their outstanding principal balances, which approximate fair value. Purchases and sales of investments are recorded on the trade dates. Interest income is recorded on the accrual basis. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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. 6 Penwest Pharmaceuticals Co. Savings Plan Notes to Financial Statements (continued) 3.

INCOME TAX STATUS The Plan has received a determination letter from the Internal Revenue Service dated November 27, 2001, stating that the Plan is qualified under Section 401(a) of the Internal Revenue code (the "Code") and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The plan administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan is qualified and the related trust is tax exempt. 5. SUBSEQUENT EVENTS On February 27, 2003, in connection with the Company's sale of substantially all of the assets used in its excipient business, the employees of the excipient business were terminated from the Company's employment and were no longer active participants, as defined in the Plan. This constituted a partial plan termination and therefore, all such employees of the excipient business with unvested Company match funds became immediately and fully vested on such date. In addition, these former employees were required to, by a specified date, elect one of several options for their existing account balances (unless their account balance was less than $5,000, in which case a full cash distribution was paid out). Options included a rollover distribution into an IRA or another eligible retirement account, taking a lump sum distribution or electing to remain a participant in the Plan in a deferred status. Through June 22, 2003, approximately $2.0 million in such termination distributions were paid out of the Plan. 8 Penwest Pharmaceuticals Co.
