Exhibit (a)(1)(I)
This announcement is neither an offer to purchase nor a solicitation of an offer to sell Shares (as defined below). The Offer (as defined below) is made solely pursuant to the Offer to Purchase, dated August 20, 2010, and the related Letter of Transmittal, and any amendments or supplements to such Offer to Purchase or Letter of Transmittal. Purchaser (as defined below) is not aware of any state where the making of the Offer is prohibited by any administrative or judicial action pursuant to any valid state statute. If Purchaser becomes aware of any valid state statute prohibiting the making of the Offer or the acceptance of the Shares pursuant thereto, Purchaser will make a good faith effort to comply with that state statute or seek to have such statute declared inapplicable to the Offer. If, after a good faith effort, Purchaser cannot do so, Purchaser will not make the Offer to nor will tenders be accepted from or on behalf of, the holders of Shares in that state. Except as set forth above, the Offer is being made to all holders of Shares. In any jurisdiction where the securities, “blue sky” or other laws require the Offer to be made by a licensed broker or dealer, the Offer will be deemed to be made on behalf of Purchaser by one or more registered brokers or dealers that are licensed under the laws of such jurisdiction.

contained in the Penwest Articles of Incorporation and the Washington Business Corporation Act (the “WBCA”) applicable to a “significant business transaction” (as defined in Chapter 23B.19 of the WBCA) will not apply to the execution, delivery or performance of the Merger Agreement or the Shareholder Tender Agreements (as defined in the Offer to Purchase), or to the consummation of the transactions contemplated by the Merger Agreement, including the Merger. The Continuing Directors of Penwest (as such term is defined in the Penwest Articles of Incorporation), voting separately as a subclass of the board of directors of Penwest, have unanimously adopted and approved the Merger Agreement and the Merger.
The purpose of the Offer is for Endo and its affiliates, through Purchaser, to acquire control of, and the entire equity interest in, Penwest. Following the consummation of the Offer, subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Purchaser intends to effect the Merger. No dissenters’ rights are available to holders of Shares in connection with the Offer, however, holders of Shares may be entitled to demand appraisal in connection with the Merger.
Subject to the provisions of the Merger Agreement and the applicable rules and regulations of the Securities and Exchange Commission (the “Commission”), Purchaser expressly reserves the right to waive any conditions to the Offer (provided, that the Minimum Tender Condition described above and certain other provisions may be waived only with the prior written consent of Penwest), or modify the terms of the Offer. Subject to the provisions of the Merger Agreement and the applicable rules and regulations of the Commission, Purchaser reserves the right, and under certain circumstances Purchaser may be required, to extend the Offer, as described in Section 1 of the Offer to Purchase. Pursuant to Rule 14d-11 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Purchaser may elect to provide a subsequent offering period of between three and 20 business days upon expiration of the Offer.
Any extension, waiver or amendment of the Offer, or delay in acceptance for payment or payment, or termination of the Offer will be followed, as promptly as practicable, by public announcement thereof, such announcement in the case of an extension to be issued no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.
For purposes of the Offer, Purchaser will be deemed to have accepted for payment, and thereby purchased, Shares validly tendered, and not properly withdrawn, prior to the Expiration Date if and when Purchaser gives oral or written notice to the Depositary of Purchaser’s acceptance for payment of such Shares pursuant to the Offer. Upon the terms and subject to the conditions of the Offer, payment for Shares accepted for payment pursuant to the Offer will be made by cash deposit of the purchase price therefor with the Depositary, which will act as agent for the tendering shareholders for the purpose of receiving payments from Purchaser and transmitting such payments to the tendering shareholders.Under no circumstances will interest be paid on the purchase price for Shares, regardless of any extension of the Offer or any delay in making payment for Shares.
In all cases (other than by conditional option or warrant exercise, for which shareholders must follow the Instructions set forth in the Instructions for Conditional Exercise for Tender of Option Shares and Warrant Shares and the Conditional Election Form), payment for Shares tendered and accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of (a) certificates for such Shares or timely confirmation of the book-entry transfer of such Shares into the Depositary’s account at The Depository Trust Company (“DTC”) pursuant to the procedures set forth in Section 3 of the Offer to Purchase, (b) a Letter of Transmittal, properly completed and duly executed, with any required signature guarantees (or, in the case of a book-entry transfer, an Agent’s Message (as defined in Section 3 of the Offer to Purchase) in lieu of the Letter of Transmittal), and (c) any other documents required by the Letter of Transmittal.
Shares tendered pursuant to the Offer (other than any Options Shares or Warrant Shares, for which a shareholder must follow the Instructions set forth in the Instructions for Conditional Exercise for Tender of Option Shares and Warrant Shares and the Conditional Election Form to withdraw Option Shares and Warrant Shares) may be withdrawn at any time prior to the Expiration Date. Thereafter, tenders of Shares are irrevocable.

For a withdrawal of Shares to be effective, a written notice of withdrawal must be timely received by the Depositary at its address set forth on the back cover of the Offer to Purchase. Any such notice of withdrawal must specify the name of the person having tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the record holder of the Shares to be withdrawn, if different from that of the person who tendered such Shares. The signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution (as defined in Section 3 of the Offer to Purchase), unless such Shares have been tendered for the account of any Eligible Institution. If Shares have been tendered pursuant to the procedures for book-entry transfer as set forth in Section 3 of the Offer to Purchase, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Shares and must otherwise comply with DTC’s procedures. If certificates for Shares to be withdrawn have been delivered or otherwise identified to the Depositary, the name of the registered holder and the serial numbers shown on such certificates must also be furnished to the Depositary as aforesaid prior to the physical release of such certificates.
All questions as to the form and validity (including time of receipt) of any notice of withdrawal will be determined by Purchaser, in its sole discretion, which determination shall be final and binding. No withdrawal of Shares shall be deemed to have been properly made until all defects and irregularities have been cured or waived. None of Endo, Purchaser or any of their respective affiliates or assigns, the Depositary, the Information Agent (listed below), or any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give such notification. Withdrawals of tenders of Shares may not be rescinded, and any Shares properly withdrawn will be deemed not to have been validly tendered for purposes of the Offer. However, withdrawn Shares may be retendered by following one of the procedures for tendering Shares described in Section 3 of the Offer to Purchase at any time prior to the Expiration Date.
The information required to be disclosed by paragraph (d)(1) of Rule 14d-6 under the Exchange Act is contained in the Offer to Purchase and is incorporated herein by reference.
