SUMMARY TERM SHEET
 
This summary term sheet is a brief description of the offer being made by FBC Acquisition Corp. (“Purchaser”), a wholly owned subsidiary of Biogen Idec Inc. (“Biogen Idec”), to purchase all of the outstanding shares of common stock, par value $0.01 per share, of Facet Biotech Corporation (the “Company”), including the associated preferred stock purchase rights issued or to be issued under the Rights Agreement, dated as of September 7, 2009, between the Company and Mellon Investor Services LLC, as Rights Agent (the “Rights” and, together with the common stock, the “Shares”), at a price of $14.50 per Share, net to the seller in cash, without interest (and less any applicable withholding taxes), upon the terms and subject to the conditions set forth in this offer to purchase and in the related letter of transmittal (which together, as amended, supplemented or otherwise modified from time to time, constitute the “Offer”). The following are some of the questions you, as a stockholder of the Company, may have, as well as answers to those questions. You should carefully read this offer to purchase and the related letter of transmittal in their entirety, because the information in this summary term sheet is not complete and additional important information is contained in the remainder of this offer to purchase and the related letter of transmittal. You may direct questions or requests for assistance to the Information Agent at its address and telephone numbers as set forth on the back cover of this offer to purchase.
 
Who is offering to buy my securities?
 
FBC Acquisition Corp., a wholly owned subsidiary of Biogen Idec Inc., is offering to purchase all of the outstanding Shares. FBC Acquisition Corp. is a Delaware corporation which Biogen Idec formed solely for the purpose of making this tender offer.
 
What are the classes and amounts of securities sought in the Offer?
 
We are seeking to purchase all of the outstanding shares of common stock, par value $0.01 per share, of the Company, along with the associated preferred stock purchase rights. On the date of this offer to purchase, Biogen Idec is the beneficial owner of 100 shares of Company common stock. The Company disclosed in its Quarterly Report on Form 10-Q for the quarter ended June 30, 2009 (the “Company Q2 2009 Report”) that, as of July 31, 2009, there were 24,559,791 shares of Company common stock outstanding. In addition, the Company disclosed in the Company Q2 2009 Report that, as of June 30, 2009, stock options covering approximately 1,863,000 shares of Company common stock were outstanding.
 
Why are you making the Offer?
 
We are making the Offer because we want to acquire control of, and ultimately the entire equity interest in, the Company. If the Offer is consummated, Biogen Idec intends, as soon as practicable after consummation of the Offer, to have Purchaser consummate a merger with the Company (the “Proposed Merger”) pursuant to which each then outstanding share of Company common stock (other than those held by Biogen Idec, held in the treasury of the Company, held by subsidiaries of the Company, if any, and held by Company stockholders who have not tendered their Shares in the Offer and who properly exercise appraisal rights) would be converted into the right to receive an amount in cash per share of Company common stock equal to the highest price per Share paid by us pursuant to the Offer, without interest (and less any applicable withholding taxes). Upon consummation of the Proposed Merger, the Company would be a wholly owned subsidiary of Biogen Idec.
 
How much are you offering to pay for my Shares and what is the form of payment? Will I have to pay any fees or commissions?
 
We are offering to pay $14.50 per Share, net to you in cash, without interest (and less any applicable withholding taxes). If you tender your Shares to us in the Offer, you will not have to pay brokerage fees, commissions or similar expenses. If you own your Shares through a broker or other nominee, and your broker tenders your Shares on your behalf, your broker or nominee may charge you a fee for doing so. You should consult your broker or nominee to determine whether any charges will apply.

Table of Contents

What are the most significant conditions to the Offer?
 
The most significant conditions to the Offer are the following, any or all of which may be waived by us, to the extent legally permissible, in our sole discretion:
 
  •  the “Minimum Condition”: the Company’s stockholders having validly tendered and not properly withdrawn prior to the expiration of the Offer that number of Shares representing, together with the Shares owned by Biogen Idec, at least a majority of the total voting power of all of the outstanding shares of the Company entitled to vote generally in the election of directors or with respect to a merger, calculated on a fully diluted basis after consummation of the Offer;
 
  •  the “Section 203 Condition”: Biogen Idec being satisfied that the restrictions on business combinations with interested stockholders set forth in Section 203 of the Delaware General Corporation Law are inapplicable to the Offer and the Proposed Merger or any other business combination involving Biogen Idec or any of its subsidiaries (including Purchaser) and the Company;
 
  •  the “Regulatory Condition”: all waiting periods under applicable antitrust laws, including the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), having expired or been terminated;
 
  •  the “Rights Condition”: the board of directors of the Company (the “Company Board”) redeeming the Rights, or Biogen Idec being satisfied that the Rights have been invalidated or are otherwise inapplicable to the Offer and the Proposed Merger; and
 
  •  the “Impairment Condition”: the Company not having entered into or effectuated any agreement or transaction with any person or entity having the effect of impairing the Purchaser’s or Biogen Idec’s ability to acquire the Company or otherwise diminishing the expected value to Biogen Idec of the acquisition of the Company other than, except as to terms not disclosed in the Company’s Current Report on Form 8-K filed with the SEC on August 31, 2009, the Collaboration and License Agreement and related Stock Purchase Agreement between the Company and Trubion Pharmaceuticals, Inc. (“Trubion”) disclosed in such Current Report.
 
In addition to the foregoing conditions, the Offer includes a number of other conditions, including the absence of certain events and conditions described in Section 15 of this offer to purchase. For a complete list of the conditions to the Offer, see “The Offer — Conditions to the Offer.”
 
The Company Board has the ability to satisfy certain of the principal conditions to the Offer, including the Section 203 Condition, the Rights Condition and the Impairment Condition. Biogen Idec and Purchaser believe that, to the extent possible, the Company Board should take all necessary actions to facilitate consummation of the Offer and hereby request that they do so. Although we believe that, under the circumstances of the Offer, the Company Board should do so, there can be no assurance that the Company Board will act to satisfy the conditions to the Offer. If the Company Board does not act to satisfy the conditions and facilitate the Offer, we will not be able to consummate the Offer.
 
How do you plan to finance the purchase of Shares in the Offer and the Proposed Merger?
 
In order to finance the purchase of all of the Shares pursuant to our Offer and the Proposed Merger and pay fees and expenses related to the transactions, Biogen Idec plans to use its available cash. We estimate that the total amount of funds required to acquire the outstanding shares pursuant to the Offer and Proposed Merger and to pay related fees and expenses will be approximately $375 million. See “The Offer — Source and Amount of Funds.”
 
Have you held discussions with the Company?
 
We have tried repeatedly to discuss with the Company the potential acquisition of the Company by Biogen Idec. We made a proposal to acquire all of the outstanding Shares in a negotiated transaction, but the Company has indicated that it has no interest in discussing a potential transaction on the terms we proposed. See “The Offer — Background of the Offer; Other Transactions with the Company.”

Table of Contents

What are the associated preferred stock purchase rights?
 
The Rights were created pursuant to the Rights Agreement (the “Rights Agreement”), dated as of September 7, 2009, between the Company and Mellon Investor Services LLC, as Rights Agent. The Company announced on September 9, 2009, that the Company Board had declared a dividend of one Right for each outstanding share of Company common stock as of September 21, 2009 to stockholders of record on that date. Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of new Series A Preferred Stock, par value $0.01 per share, of the Company at a price of $50.
 
The Rights are not exercisable until a “distribution” of such Rights occurs. Absent action by the Company Board, the announcement or commencement of the Offer would result in a distribution of the Rights 10 business days following such announcement or commencement, with no further action from any party. Until a distribution occurs, the Rights will be evidenced by the shares of Company common stock with which they are associated and will be transferred with and only with such shares.
 
We believe that if the Rights Condition is satisfied, the Rights Agreement will not be an impediment to consummating either the Offer or the Proposed Merger. However, unless and until the Rights Condition is satisfied, the existence of the Rights has the practical effect of precluding Biogen Idec and Purchaser from consummating the Offer, regardless of the extent to which the Company’s stockholders wish to sell their Shares pursuant to the Offer. Unless a distribution of the Rights occurs, a tender of shares of Company common stock will include a tender of the associated Rights. If a distribution does occur, you will need to tender one Right with each share of Company common stock tendered. We will not pay any additional consideration for the tender of a Right. See “The Offer — Procedure for Tendering Shares,” “— Certain Information Concerning the Company — Preferred Stock Purchase Rights” and ‘‘— Conditions to the Offer.”
 
How long do I have to decide whether to tender in the Offer?
 
You have until 12:00 midnight, New York City time, on October 19, 2009, to tender your Shares in the Offer, unless the Offer is extended by Purchaser. If you cannot deliver everything required to make a valid tender to Computershare Trust Company, N.A., the depositary for the Offer (the “Depositary”), prior to such time, you may be able to use a guaranteed delivery procedure to tender your Shares in the Offer, which is described in “The Offer — Procedure for Tendering Shares.”
 
Can the Offer be extended and under what circumstances?
 
We may, in our sole discretion, extend the Offer at any time or from time to time. We may extend the Offer, for example, if any of the conditions specified in “The Offer — Conditions to the Offer” are not satisfied prior to the scheduled expiration date of the Offer.
 
We may also elect to provide a “subsequent offering period” for the Offer. A subsequent offering period, if we include one, will be an additional period of time beginning after we have purchased Shares tendered during the Offer, during which stockholders may tender their Shares and receive payment for Shares validly tendered. We do not currently intend to include a subsequent offering period, although we reserve the right to do so. See “The Offer — Terms of the Offer; Expiration Date.”
 
How will I be notified if the Offer is extended?
 
If we decide to extend the Offer or provide for a subsequent offering period, we will inform the Depositary of that fact and will make a public announcement of the extension, not later than 9:00 a.m., New York City time, on the business day after the day on which the Offer was scheduled to expire.
 
How do I tender my Shares?
 
To tender Shares, you must either (i) deliver the Shares (via book entry transfer as described under “The Offer — Procedure for Tendering Shares”) or (ii) if your Shares are held in a book-entry/direct registration system account maintained with the Company’s transfer agent (a “DRS Account”) complete, sign and deliver the letter of transmittal, in each case to the Depositary not later than the time that the Offer expires. If your Shares are held in

Table of Contents

street name by your broker, dealer, commercial bank, trust company or other nominee, such nominee can tender your Shares through The Depository Trust Company. If you cannot deliver everything required to make a valid tender to the Depositary prior to the expiration of the Offer, you may have a limited amount of additional time by having a broker, a bank or other fiduciary which is a member of the Securities Transfer Agents Medallion Program or other eligible institution guarantee that the missing items will be received by the Depositary within three business days after the expiration of the Offer. However, the Depositary must receive the missing items within that three business day period. See “The Offer — Procedure for Tendering Shares.”
 
Until what time can I withdraw tendered Shares?
 
You can withdraw tendered Shares at any time until the Offer has expired and, if we have not accepted your Shares for payment by the date that is 60 days from the date of the original Offer, you can withdraw them at any time after such date until we accept Shares for payment. If we decide to provide a subsequent offering period, we will accept Shares tendered during that period immediately and, thus, you will not be able to withdraw Shares tendered during any subsequent offering period. See “The Offer — Withdrawal Rights.”
 
How do I withdraw tendered Shares?
 
To withdraw Shares, you must deliver a written notice of withdrawal with the required information to the Depositary while you have the right to withdraw the Shares. See “The Offer — Withdrawal Rights.”
 
When and how will I be paid for my tendered Shares?
 
Subject to the terms and conditions of the Offer, we will pay for all validly tendered and not properly withdrawn Shares promptly after the expiration of the Offer, subject to the satisfaction or waiver of the conditions to the Offer, as set forth in “The Offer — Conditions to the Offer.” We will pay for your validly tendered and not properly withdrawn Shares by depositing the purchase price with the Depositary, which will act as your agent for the purpose of receiving payments from us and transmitting such payments to you. In all cases, payment for tendered Shares will be made only after timely receipt by the Depositary of a confirmation of a book-entry transfer of such Shares and an “Agent’s Message” or, in the case of shares held in a DRS Account, a properly completed and duly executed letter of transmittal, and any other required documents for such Shares or such tender.
 
If I decide not to tender, how will the Offer affect my Shares?
 
As indicated above, if the Offer is consummated, Biogen Idec intends, as soon as practicable after consummation of the Offer, to have Purchaser consummate a merger with the Company. If the Proposed Merger with Purchaser takes place, stockholders not tendering in the Offer (other than those stockholders who properly seek appraisal of their Shares) will receive the same amount of cash per Share that they would have received had they tendered their Shares in the Offer. Therefore, if the Proposed Merger with Purchaser takes place, the only difference to you between tendering your Shares and not tendering your Shares is that you will be paid earlier if you tender your Shares. Under no circumstances will Biogen Idec or Purchaser pay any interest on the purchase price for Shares by reason of any extension of the Offer or delay of stockholders in tendering their Shares.
 
Upon consummation of the Proposed Merger, the Company would be a wholly owned subsidiary of Biogen Idec. However, until the Proposed Merger with Purchaser takes place after the Offer is consummated, the number of stockholders and Shares that are still in the hands of the public may be so small that there will no longer be an active public trading market, or, possibly, any public trading market, for the Shares, which may affect prices at which Shares trade. Also, as described below, depending upon the number of Company stockholders following consummation of the Offer, the Company may cease making filings with the SEC or otherwise cease being subject to the SEC rules relating to publicly held companies.
 
Do I have statutory dissenters’ (or appraisal) rights in the Offer?
 
Appraisal rights are not available in the Offer. After the Offer, if the Proposed Merger takes place, appraisal rights will be available to holders of shares of Company common stock who do not vote in favor of the Proposed Merger and who properly seek appraisal rights for their shares in accordance with Section 262 of the General

Table of Contents

Corporation Law of the State of Delaware. The value you would receive if you perfect appraisal rights could be more or less than, or the same as, the price per Share to be paid in the Offer and Proposed Merger. See “The Offer — Certain Legal Matters; Regulatory Approvals.”
 
What is the market value of my common shares as of a recent date?
 
On September 3, 2009, the last full trading day before we publicly announced our proposal to acquire all of the outstanding shares of common stock of the Company for $14.50 per share in cash, the closing price of a share of common stock of the Company on Nasdaq was $8.82. The offer price of $14.50 per Share represents a premium of approximately 64% over the Company’s closing stock price on that date. On September 18, 2009, the last full trading day before we commenced the Offer, the closing price of a share of common stock of the Company on Nasdaq was $16.55. We advise you to obtain a current market quotation for your Shares before deciding whether to tender.
 
What are the material U.S. federal income tax consequences of receiving cash in exchange for Shares pursuant to the Offer or the Proposed Merger?
 
The receipt of cash in exchange for Shares pursuant to the Offer or the Proposed Merger will be a taxable transaction for U.S. federal income tax purposes. In general, you will recognize gain or loss for U.S. federal income tax purposes equal to the difference, if any, between the amount of cash received and your adjusted tax basis in the Shares sold. You should consult your tax advisor regarding the particular tax consequences of the Offer and the Proposed Merger to you, including the tax consequences under state, local, foreign and other tax laws.

To: The Holders of Common Stock of Facet Biotech Corporation
 
INTRODUCTION
 
FBC Acquisition Corp., a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of Biogen Idec Inc., a Delaware corporation (“Biogen Idec”), hereby offers to purchase all of the outstanding shares of common stock, par value $0.01 per share, of Facet Biotech Corporation (the “Company”), including the associated preferred stock purchase rights issued or to be issued under the Rights Agreement, dated as of September 7, 2009, between the Company and Mellon Investor Services LLC, as Rights Agent (the “Rights” and, together with the Company common stock, the “Shares”), at a price of $14.50 per Share, net to the seller in cash, without interest (and less any applicable withholding taxes), upon the terms and subject to the conditions set forth in this offer to purchase and in the related letter of transmittal (which together, as amended, supplemented or otherwise modified from time to time, constitute the “Offer”).
 
Stockholders will be required to tender one Right for each Share tendered in order to effect a valid tender of Shares in accordance with the procedure set forth in “The Offer — Procedure for Tendering Shares.” Unless the Rights have been distributed, a tender of Company common stock will also constitute a tender of the associated Rights.
 
If you tender your Shares to us in the Offer, you will not be obligated to pay brokerage fees, commissions or, except as set forth in Instruction 5 of the letter of transmittal, transfer taxes on the sale of your Shares pursuant to the Offer. If you own your Shares through a broker or other nominee, and your broker tenders Shares on your behalf, your broker or nominee may charge you a fee for doing so. You should consult your broker or nominee to determine whether any such charges will apply. We will pay all charges and expenses of Computershare Trust Company, N.A. (the “Depositary”) and Innisfree M&A Incorporated (the “Information Agent”) incurred in connection with the Offer. See “The Offer — Fees and Expenses.”
 
The purpose of the Offer and the Proposed Merger (as defined below) is to enable Biogen Idec to acquire control of, and the entire equity interest in, the Company. Biogen Idec currently intends, as soon as practicable following consummation of the Offer, to seek to have Purchaser consummate a merger with and into the Company (the “Proposed Merger”), with the Company continuing as the surviving corporation and a wholly owned subsidiary of Biogen Idec. Pursuant to the Proposed Merger, at the effective time of the Proposed Merger (the “Effective Time”), each Share then outstanding that is not owned by Biogen Idec, Purchaser or other subsidiaries of Biogen Idec (other than Shares owned by the Company) or held by a Company stockholder who has not tendered their Shares in the Offer and who properly exercises appraisal rights would be converted, pursuant to the terms of the Proposed Merger, into the right to receive an amount in cash equal to the per Share price paid pursuant to the Offer, without interest (and less any applicable withholding taxes).
 
Biogen Idec is seeking to negotiate with the Company with respect to the acquisition of the Company by Biogen Idec. Biogen Idec and Purchaser reserve the right, subject to applicable laws and regulations, in their sole discretion, at any time and from time to time to (i) amend the Offer (including amending the number of Shares to be purchased and/or amending the purchase price) upon entering into a merger agreement with the Company or (ii) negotiate a merger agreement with the Company that does not involve a tender offer for Shares and pursuant to which merger agreement Purchaser would terminate the Offer and the Shares would, upon consummation of the merger contemplated by such merger agreement, be converted into the consideration negotiated by Biogen Idec, Purchaser and the Company.
 
The Offer is conditioned upon, among other things, (1) there being validly tendered and not properly withdrawn prior to the expiration of the Offer a total number of Shares representing, together with the Shares owned by Biogen Idec, at least a majority of the total voting power of all of the outstanding shares of the Company entitled to vote generally in the election of directors or with respect to a merger, calculated on a fully diluted basis after consummation of the Offer (the “Minimum Condition”), (2) Biogen Idec being satisfied that the restrictions on business combinations with interested stockholders set forth in Section 203 of the Delaware General Corporation Law are inapplicable to the Offer and the Proposed Merger or any other business combination involving Biogen Idec or any of its subsidiaries (including Purchaser) and the Company (the “Section 203 Condition”), (3) all waiting periods under applicable antitrust laws, including the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, having expired or been terminated

Table of Contents

(the “Regulatory Condition”), (4) the Company’s board of directors redeeming the preferred stock purchase rights, or Biogen Idec being satisfied that such rights have been invalidated or are otherwise inapplicable to the Offer and the Proposed Merger (the “Rights Condition”) and (5) the Company not having entered into or effectuated any agreement or transaction with any person or entity having the effect of impairing Purchaser’s or Biogen Idec’s ability to acquire the Company or otherwise diminishing the expected value to Biogen Idec of the acquisition of the Company other than, except as to terms not disclosed in the Company’s Current Report on Form 8-K filed with the SEC on August 31, 2009, the Collaboration and License Agreement and related Stock Purchase Agreement between the Company and Trubion Pharmaceuticals, Inc. disclosed in such Current Report (the “Impairment Condition”).
 
In the event that the Offer is terminated or not consummated, or after the expiration of the Offer and pending consummation of the Proposed Merger, in accordance with applicable law and any merger agreement that it may enter into with the Company, Biogen Idec may explore any and all options which may be available. In this regard, and after expiration or termination of the Offer, Biogen Idec may seek to acquire additional Shares through open market purchases, block trades, privately negotiated transactions, a tender offer or exchange offer or otherwise, upon such terms and at such prices as Biogen Idec may determine, which may be more or less than the price offered or paid per Share pursuant to the Offer and could be for cash or other consideration.
 
THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT INFORMATION, AND YOU SHOULD CAREFULLY READ BOTH IN THEIR ENTIRETY BEFORE YOU MAKE A DECISION WITH RESPECT TO THE OFFER.
 
THIS OFFER DOES NOT CONSTITUTE A SOLICITATION OF PROXIES FOR ANY MEETING OF STOCKHOLDERS OF THE COMPANY.
 
THE OFFER
 
1.   Terms of the Offer; Expiration Date.
 
On the terms and subject to the conditions set forth in this Offer (including, if the Offer is extended or amended, the terms and conditions of such extension or amendment), we will accept for payment and pay for all Shares that are validly tendered and not properly withdrawn prior to the Expiration Date.
 
Expiration Date” means 12:00 midnight, New York City time, on October 19, 2009, unless we extend the period of time for which the Offer is open, in which event, “Expiration Date” means the latest time and date on which the Offer, as so extended, shall expire.
 
The Offer is conditioned upon, among other things, the satisfaction of (1) the Minimum Condition, (2) the Section 203 Condition, (3) the Regulatory Condition, (4) the Rights Condition and (5) the Impairment Condition. The Offer is also subject to other conditions as described in “The Offer — Conditions to the Offer.” If any of the conditions are not satisfied immediately prior to any scheduled expiration date, we may: (i) terminate the Offer and return all tendered Shares; (ii) extend the Offer and, subject to certain conditions and to your withdrawal rights as set forth in “The Offer — Withdrawal Rights,” retain all Shares until the Expiration Date as so extended; or (iii) waive the unsatisfied conditions and, subject to any requirement to extend the period of time during which the Offer must remain open, purchase all Shares validly tendered prior to the Expiration Date and not properly withdrawn or delay acceptance for payment or payment for Shares, subject to applicable law, until satisfaction or waiver of the conditions to the Offer. For a description of our right to extend, amend, delay or terminate the Offer, see “The Offer — Extension of Tender Period; Termination; Amendment” and “The Offer — Conditions to the Offer.”
 
On the date of this offer to purchase, Biogen Idec owns beneficially 100 shares of common stock of the Company. The Company disclosed in the Company Q2 2009 Report that, as of July 31, 2009, there were 24,559,791 shares of Company common stock outstanding. In addition, the Company disclosed in the Company Q2 2009 Report that, as of June 30, 2009, stock options covering approximately 1,863,000 shares of Company common stock were outstanding. For purposes of calculating satisfaction of the Minimum Condition, “fully diluted basis” assumes that all outstanding stock options are fully exercisable. The actual minimum number of Shares required to satisfy the Minimum Condition will depend on the facts as they exist on the date of purchase.

We may, subject to certain conditions, elect to provide a subsequent offering period of between three business days and 20 business days in length after the expiration of the Offer on the Expiration Date and acceptance for payment of the Shares tendered in the Offer (a “Subsequent Offering Period”). A Subsequent Offering Period would be an additional period of time, after completion of the first purchase of Shares in the Offer, during which stockholders would be able to tender Shares not tendered in the Offer. During a Subsequent Offering Period, tendering stockholders would not have withdrawal rights and we would promptly purchase and pay for any Shares tendered at the same price as paid in the Offer. We may provide a Subsequent Offering Period so long as, among other things:
 
(1) the initial 20-business day period of the Offer has expired;
 
(2) we offer the same form and amount of consideration for Shares in the Subsequent Offering Period as in the initial Offer;
 
(3) we immediately accept and promptly pay for all Shares tendered during the Offer and prior to its expiration;
 
(4) we announce the results of the Offer, including the approximate number and percentage of Shares deposited in the Offer, no later than 9:00 a.m., New York City time, on the next business day after the Expiration Date and immediately begin the Subsequent Offering Period; and
 
(5) we immediately accept and promptly pay for Shares as they are tendered during the Subsequent Offering Period.
 
A Subsequent Offering Period, if one is included, is not an extension of the Offer, which would already have been completed. We do not currently intend to include a Subsequent Offering Period with the Offer, although we reserve the right to do so in our sole discretion.
 
Under Rule 14d-7 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), no withdrawal rights apply to Shares tendered during a Subsequent Offering Period and no withdrawal rights apply during the Subsequent Offering Period with respect to Shares tendered in the Offer and accepted for payment.
 
This offer to purchase, the letter of transmittal and all other relevant materials will be mailed to record holders of Shares and will be furnished to brokers, dealers, banks, trust companies and similar persons whose names, or the names of whose nominees, appear on the Company’s stockholders lists, or, if applicable, who are listed as participants in a clearing agency’s security position listing for subsequent transmittal to beneficial owners of Shares.
 
2.   Extension of Tender Period; Termination; Amendment.
 
We reserve the right, subject to applicable laws and regulations, in our sole discretion, at any time and from time to time, (i) to extend the period of time during which the Offer is open, and thereby delay the acceptance of, and the payment for, the Shares and (ii) to amend the Offer in any other respect, by giving notice of such extension or amendment to the Depositary. We also have the right to extend the Offer for any period required by any rule, regulation, interpretation or position of the SEC or the SEC Staff applicable to the Offer or any period required by applicable law. We expressly reserve the right to waive (to the extent legally permissible) any of the conditions to the Offer, to make any change in the terms of our conditions to the Offer (including the addition of new conditions) and to provide a Subsequent Offering Period for the Offer in accordance with the Exchange Act Rule 14d-11.
 
If we make a material change in the terms of the Offer, or if we waive a material condition to the Offer, we will extend the Offer and disseminate additional tender offer materials to the extent required by Rules 14d-4(d)(1), 14d-6(c) and 14e-1 under the Exchange Act. The minimum period during which the Offer must remain open following material changes in the terms of the Offer, other than a change in price, a change in the percentage of securities sought or a change in any dealer’s soliciting fee, will depend upon the facts and circumstances, including the materiality of the changes. In contrast, a minimum 10-business day period from the date of such change is generally required to allow for adequate dissemination of new information to stockholders in connection with a change in price or, subject to certain limitations, a change in the percentage of securities sought or a change in any

Table of Contents

dealer’s soliciting fee. For purposes of the Offer, a “business day” means any day other than a Saturday, Sunday or a federal holiday, and consists of the time period from 12:01 a.m. through 12:00 midnight, New York City time.
 
If we decide, in our sole discretion, to increase (or decrease) the consideration offered in the Offer to holders of Shares and if, at the time that notice of the increase (or decrease) is first published, sent or given to holders of Shares, the Offer is scheduled to expire at any time earlier than the expiration of a period ending on the tenth business day from, and including, the date that such notice is first so published, sent or given, then the Offer will be extended until at least the expiration of 10 business days from the date the notice of the increase (or decrease) is first published, sent or given to holders of Shares.
 
If, on or before the Expiration Date, we increase the consideration being paid for Shares accepted for payment pursuant to the Offer, such increased consideration will be paid to all stockholders whose Shares are purchased in the Offer, whether or not such Shares were tendered before the announcement of the increase in consideration.
 
Any extension, delay, termination, waiver or amendment will be followed as promptly as practicable by a public announcement, in the case of an extension of the Offer, to be made no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date, in accordance with the public announcement requirements of Exchange Act Rule 14e-1(d). Subject to applicable law (including Exchange Act Rules 14d-4(d) and 14d-6(c), which require that material changes in the information published, sent or given to any stockholders in connection with the Offer be promptly disseminated to stockholders in a manner reasonably designed to inform them of such changes), and without limiting the manner in which we may choose to make any public announcement, we currently intend to make announcements regarding the Offer by issuing a press release.
 
If we extend the time during which the Offer is open, or if we are delayed in our acceptance for payment of or payment for Shares pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer, the Depositary may retain tendered Shares on our behalf and those Shares may not be withdrawn except to the extent tendering stockholders are entitled to withdrawal rights as described in this offer to purchase under “The Offer — Withdrawal Rights.” However, our ability to delay the payment for Shares that we have accepted for payment is limited by Exchange Act Rule 14e-1(c), which requires that a bidder pay the consideration offered or return the securities deposited by or on behalf of stockholders promptly after the termination or withdrawal of the bidder’s offer.
 
3.   Acceptance for Payment and Payment.
 
Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any such extension or amendment), we will accept for payment and pay for all Shares that are validly tendered on or prior to the Expiration Date and not properly withdrawn pursuant to the Offer as soon as we are permitted to do so under applicable law, subject to the satisfaction or waiver of the conditions set forth in “The Offer — Conditions to the Offer.” In addition, we reserve the right, subject to compliance with Exchange Act Rule 14e-1(c), to delay the acceptance for payment or payment for Shares pending receipt of any regulatory or governmental approvals in respect of the Offer as described in this offer to purchase under “The Offer — Certain Legal Matters; Regulatory Approvals.” For a description of our right to terminate the Offer and not accept for payment or pay for Shares or to delay acceptance for payment of, or payment for, Shares, see “The Offer — Extension of Tender Period; Termination; Amendment.”
 
For purposes of the Offer, we will be deemed to have accepted for payment tendered Shares when, as and if we give notice of our acceptance to the Depositary. We will pay for Shares accepted for payment pursuant to the Offer by depositing the purchase price with the Depositary. The Depositary will act as your agent for the purpose of receiving payments from us and transmitting such payments to you. In all cases, payment for Shares accepted for payment pursuant to the Offer will be made only after (i) timely receipt by the Depositary of a confirmation of a book-entry transfer of such Shares into the Depositary’s account at the Book-Entry Transfer Facility (as defined in “The Offer — Procedure for Tendering Shares”) and an Agent’s Message (as defined in “The Offer — Procedure for Tendering Shares”) or (ii) if your Shares are held in a DRS Account, timely receipt by the Depositary of a properly completed and duly executed letter of transmittal and any other documents required by the letter of transmittal. Accordingly, payment may be made to tendering stockholders at different times if delivery of the Shares

and other required documents occurs at different times. For a description of the procedure for tendering Shares pursuant to the Offer, see “The Offer — Procedure for Tendering Shares.”
 
Under no circumstances will we pay interest on the consideration paid for Shares pursuant to the Offer, regardless of any delay in making such payment. If we increase the consideration to be paid for Shares pursuant to the Offer, we will pay such increased consideration for all Shares purchased pursuant to the Offer.
 
We reserve the right to transfer or assign, in whole or, from time to time, in part, to one or more of our affiliates the right to purchase Shares tendered pursuant to the Offer, but any such transfer or assignment will not relieve us of our obligations under the Offer or prejudice your rights to receive payment for Shares validly tendered and accepted for payment.
 
If any tendered Shares are not purchased pursuant to the Offer for any reason, such Shares will be returned by crediting an account maintained at the Book-Entry Transfer Facility (as defined below) or, if applicable, your DRS Account, without expense to you, as promptly as practicable following the expiration or termination of the Offer.
 
4.   Procedure for Tendering Shares.
 
Valid Tender of Shares.  To validly tender Shares pursuant to the Offer, either (i) the Depositary must receive at one of its addresses set forth on the back cover of this offer to purchase either, (A) delivery of such Shares pursuant to the procedures for book-entry transfer described below (and a confirmation of such delivery by an Agent’s Message (as defined below)) or (B) if your Shares are held in a DRS Account, a properly completed and duly executed letter of transmittal and any other documents required by the letter of transmittal, in each case by the Expiration Date, or (ii) you must comply with the guaranteed delivery procedure described below.
 
The delivery of Shares and the method of delivery of all required documents, including delivery through the Book-Entry Transfer Facility (as defined below), is at the option and risk of the tendering stockholder, and the delivery will be deemed made only when actually received by the Depositary, including, if applicable, an Agent’s Message (as defined below). If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.
 
Book-Entry Delivery.  The Depositary will establish an account with respect to the Shares at The Depository Trust Company (the “Book-Entry Transfer Facility”) for purposes of the Offer, and any financial institution that is a participant in the system of the Book-Entry Transfer Facility may make delivery of Shares by (i) causing the Book-Entry Transfer Facility to transfer such Shares into the Depositary’s account in accordance with the procedures of the Book-Entry Transfer Facility and deliver an Agent’s Message (as defined below) to the Depositary by the Expiration Date, or (ii) complying with the guaranteed delivery procedure described below. “Agent’s Message” means a message, transmitted by the Book-Entry Transfer Facility to, and received by, the Depositary and forming a part of a book-entry confirmation which provides that the Book-Entry Transfer Facility has received an express acknowledgment from the participant in the Book-Entry Transfer Facility tendering the Shares that such participant has received, and agrees to be bound by, the terms of the letter of transmittal and that Purchaser may enforce such agreement against such participant.
 
Direct Registration Account.  If you hold your Shares in a book-entry/direct registration account maintained by the Company’s transfer agent (a “DRS Account”) (and not through a financial institution that is a participant in the system of the Book-Entry Transfer Facility) in order to validly tender your Shares you must deliver the letter of transmittal, properly completed and duly executed, together with any required signature guarantees and any other required documents to the Depositary at one of its addresses set forth on the back cover of this offer to purchase by the Expiration Date, or you must comply with the guaranteed delivery procedure described below.
 
Signature Guarantees.  Except as otherwise provided below, all signatures on a letter of transmittal must be guaranteed by a financial institution (including most banks, savings and loan associations and brokerage houses) that is a member of a recognized Medallion Program approved by The Securities Transfer Association, Inc. (each an “Eligible Institution”). Signatures on a letter of transmittal need not be guaranteed (i) if the letter of transmittal is signed by the registered holder of the Shares tendered therewith or (ii) if such Shares are tendered for the account of an Eligible Institution. See Instructions 1 and 4 of the letter of transmittal for more information.

Table of Contents

Guaranteed Delivery.  If you wish to tender Shares pursuant to the Offer and cannot complete the procedure for delivery by book-entry transfer on a timely basis, or, in the case of Shares held in a DRS Account, cannot deliver all required documents to the Depositary by the Expiration Date, you may nevertheless tender such Shares if all of the following conditions are met:
 
(i) such tender is made by or through an Eligible Institution;
 
(ii) a properly completed and duly executed Notice of Guaranteed Delivery in the form provided by Purchaser is received by the Depositary (as provided below) by the Expiration Date; and
 
(iii) either (A) a confirmation of a book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility, together with an Agent’s Message, or (B) in the case of Shares held in a DRS Account, a properly completed and duly executed letter of transmittal with any required signature guarantee and any other documents required by the letter of transmittal, are received by the Depositary, in each case within three business days after the date of execution of the notice of guaranteed delivery.
 
The notice of guaranteed delivery may be mailed to the Depositary and must include a guarantee by an Eligible Institution in the form set forth in such notice.
 
The delivery of Shares and the method of delivery of all required documents, including through the Book-Entry Transfer Facility, is at your option and risk, and the delivery will be deemed made only when actually received by the Depositary. If any documents are sent by mail, we recommend registered mail with return receipt requested, properly insured. The procedures for guaranteed delivery above may not be used during any Subsequent Offering Period.
 
Backup Withholding.  Under U.S. federal income tax law, you may, under certain circumstances, be subject to information reporting and backup withholding at the applicable rate (currently, 28%) with respect to the amount of any payments made pursuant to the Offer. To avoid backup withholding, you must provide the Depositary with (i) your correct taxpayer identification number (“TIN”) and otherwise comply with the applicable requirements of the backup withholding rules or (ii) if applicable, an adequate basis for exemption. All stockholders surrendering Shares pursuant to the Offer that are U.S. persons should complete and sign the Form W-9 included with the letter of transmittal to provide the information and certifications necessary to avoid backup withholding, or otherwise establish a basis for exemption. Certain stockholders (including, among others, all corporations and certain foreign persons) are not subject to backup withholding. In order for a foreign stockholder to qualify as an exempt recipient, such stockholder should complete and sign an appropriate Form W-8 (a copy of which may be obtained from the Depositary) attesting to such person’s exempt status.
 
Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from payments made to a stockholder may be refunded or credited against the stockholder’s U.S. federal income tax liability, if any, provided that the required information is furnished to the Internal Revenue Service in a timely manner.
 
Grant of Proxy.  By delivering an Agent’s Message or executing a letter of transmittal as set forth above, you irrevocably appoint designees of Purchaser as your proxies in the manner set forth in the letter of transmittal to the full extent of your rights with respect to the Shares tendered and accepted for payment by us (and any and all other Shares or other securities issued or issuable in respect of such Shares on or after the date of this offer to purchase). All such proxies are irrevocable and coupled with an interest in the tendered Shares. Such appointment is effective only upon our acceptance for payment of such Shares. Upon such acceptance for payment, all prior proxies and consents granted by you with respect to such Shares and other securities will, without further action, be revoked, and no subsequent proxies may be given nor subsequent written consents executed (and, if previously given or executed, will cease to be effective). Our designees will be empowered to exercise all your voting and other rights as they, in their sole discretion, may deem proper at any annual, special or adjourned meeting of the Company’s stockholders, by written consent or otherwise. We reserve the right to require that, in order for Shares to be validly tendered, immediately upon our acceptance for payment of such Shares, we are able to exercise full voting rights with respect to such Shares and other securities (including voting at any meeting of stockholders then scheduled or, if applicable, acting by written consent without a meeting).


11


Table of Contents

The foregoing proxies are effective only upon acceptance for payment of Shares pursuant to the Offer. The Offer does not constitute a solicitation of proxies for any meeting of the Company’s stockholders, which, if sought, would be solicited only pursuant to separate proxy solicitation materials complying with the Exchange Act.
 
The tender of Shares pursuant to any one of the procedures described above will constitute your acceptance of the Offer, as well as your representation and warranty that (i) you own the Shares being tendered and (ii) you have the full power and authority to tender, sell, assign and transfer the Shares tendered, as specified in the letter of transmittal. Our acceptance for payment of Shares tendered by you pursuant to the Offer will constitute a binding agreement between us with respect to such Shares, upon the terms and subject to the conditions of the Offer.
 
Validity.  We will determine, in our sole discretion, all questions as to the form of documents and the validity, eligibility (including time of receipt) and acceptance for payment of any tender of Shares, and our determination shall be final and binding. We reserve the absolute right to reject any or all tenders of Shares that we determine not to be in proper form or the acceptance for payment of or payment for which may, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any defect or irregularity in any tender of Shares. Our interpretation of the terms and conditions of the Offer will be final and binding. None of Biogen Idec, Purchaser, the Depositary, the Information Agent or any other person will be under any duty to give notification of any defect or irregularity in tenders or waiver of any such defect or irregularity or incur any liability for failure to give any such notification.
 
5.   Withdrawal Rights.
 
You may withdraw tenders of Shares made pursuant to the Offer at any time prior to the Expiration Date. Thereafter, such tenders are irrevocable, except that if we have not accepted your Shares for payment by the date that is 60 days from the date of the original Offer, they may be withdrawn at any time after such date until such Shares are accepted for payment as provided in this offer to purchase. If we are delayed in accepting for payment or paying for Shares pursuant to the Offer for any reason or are unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer, the Depositary may, on our behalf, retain all Shares tendered, and such Shares may not be withdrawn except as otherwise provided in this section. Any such delay will be by an extension of the Offer to the extent required by law.
 
To withdraw tendered Shares, a written notice of withdrawal with respect to the Shares must be timely received by the Depositary at one of its addresses set forth on the back cover of this offer to purchase, and the notice of withdrawal must specify the name of the person(s) who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the registered holder of Shares, if different from that of the person(s) who tendered such Shares. If the Shares to be withdrawn have been delivered to the Depositary, a signed notice of withdrawal with (except in the case of Shares tendered by an Eligible Institution) signatures guaranteed by an Eligible Institution must be submitted prior to the release of such Shares. In addition, such notice must specify (i) in the case of Shares tendered by book-entry transfer, the name and number of the account at the Book-Entry Transfer Facility to be credited with the withdrawn Shares or, (ii) in the case of Shares held in a DRS Account, the name and number of the DRS Account.
 
Withdrawals may not be rescinded, and Shares withdrawn will thereafter be deemed not validly tendered for purposes of the Offer. However, withdrawn Shares may be re-tendered by again following one of the procedures described in “The Offer — Procedure for Tendering Shares” at any time prior to the Expiration Date.
 
We will determine, in our sole discretion, all questions as to the form and validity (including time of receipt) of any notice of withdrawal, and our determination shall be final and binding. None of Biogen Idec, Purchaser, the Depositary, the Information Agent or any other person will be under any duty to give notification of any defect or irregularity in any notice of withdrawal or waiver of any such defect or irregularity or incur any liability for failure to give any such notification.
 
If Purchaser provides a Subsequent Offering Period following the Offer, no withdrawal rights will apply to Shares tendered during that Subsequent Offering Period or to Shares tendered in the Offer and accepted for payment.

6.   Material U.S. Federal Income Tax Consequences.
 
The following is a general discussion of the material U.S. federal income tax consequences of the Offer and the Proposed Merger to holders of Shares. As used herein, “holder” means a beneficial owner of Shares that is (i) an individual citizen or resident of the United States, (ii) a corporation (including any entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any State or the District of Columbia, (iii) a trust if it is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust, or has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person, or (iv) an estate the income of which is subject to U.S. federal income tax regardless of its source. This summary is based on the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable current and proposed U.S. Treasury Regulations promulgated thereunder, judicial authority and administrative rulings and practice, all of which are subject to change, possibly on a retroactive basis. Any such change could affect the accuracy of the statements and conclusions set forth herein.
 
This discussion assumes that a holder holds Shares as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all aspects of U.S. federal income tax that may be relevant to a holder in light of its particular circumstances, or that may apply to a holder that is subject to special treatment under the U.S. federal income tax laws (including, for example, insurance companies, dealers in securities or foreign currencies, traders in securities who elect the mark-to-market method of accounting, stockholders liable for the alternative minimum tax, persons that have a functional currency other than the U.S. dollar, tax-exempt organizations, financial institutions, mutual funds, non-U.S. persons, stockholders who hold Shares as part of a hedge, straddle, constructive sale or conversion transaction, stockholders who acquired Shares through the exercise of employee stock options or other compensation arrangements, or persons that are partners in an entity or arrangement treated as a partnership for U.S. federal income tax purposes that holds Shares). This discussion does not address the tax consequences of the Proposed Merger to holders of Shares who validly exercise dissenters’ rights with respect to their Shares. In addition, the discussion does not address any tax considerations under state, local or non-U.S. laws or U.S. federal laws other than those pertaining to U.S. federal income tax.
 
The receipt of cash pursuant to the Offer or the Proposed Merger by holders of Shares will be a taxable transaction for U.S. federal income tax purposes. In general, a holder of Shares will recognize gain or loss equal to the difference, if any, between (i) the amount of cash received in exchange for such Shares and (ii) the holder’s adjusted tax basis in such Shares. If a holder acquired different blocks of Shares at different times or different prices, the holder must calculate its gain or loss and determine its adjusted tax basis and holding period separately with respect to each block of Shares. If the holding period in the Shares surrendered in the Offer or the Proposed Merger, as applicable, is greater than one year, the gain or loss will be long-term capital gain or loss. Capital losses are subject to limitations on deductibility for both corporate and non-corporate holders.
 
See Section 4 of this offer to purchase with respect to the application of U.S. federal income tax backup withholding to payments made pursuant to the Offer.
 
Holders of Shares should consult their own tax advisor to determine the particular tax consequences to them, including the application and effect of any state, local or non-U.S. income and other tax laws, of the receipt of cash in exchange for Shares pursuant to the Offer or the Proposed Merger.

8.   Certain Information Concerning the Company.
 
General.  The following information is based solely on publicly available documents filed by the Company with the SEC. The Company was organized as a Delaware corporation in July 2008 by PDL as a wholly owned subsidiary of PDL. PDL organized the Company in preparation for the spin-off of the Company, which was effected on December 18, 2008 (the “Company Spin-off”). In connection with the Company Spin-off, PDL contributed to the Company PDL’s Biotechnology Business and PDL distributed to its stockholders all of the outstanding shares of Company common stock. Following the Company Spin-off, the Company became an independent, publicly traded company owning and operating what previously had been PDL’s Biotechnology Business. The Company operates in one segment and its facilities are located primarily in the United States.
 
As of the date of the Company Q2 2009 Report, the Company had several investigational compounds in various stages of development for the treatment of cancer and immunologic diseases, three of which the Company was developing with collaboration partners; two with Biogen Idec and one with Bristol-Myers Squibb Company (“BMS”). The table below lists the antibodies for which the Company was, as of that date, pursuing development activities either on its own or in collaboration with other companies. These product candidates are at early stages of development, and none of the Company’s product candidates have been approved by the United States Food and Drug Administration or commercialized in the indication in which the Company’s trials are focused. (Not all clinical trials for each product candidate are listed below).

Daclizumab.  Daclizumab is a humanized monoclonal antibody that binds to the alpha chain (CD25) of the interleukin-2 (IL-2) receptor on activated T cells, which are white blood cells that play a role in inflammatory and immune-mediated processes in the body. Daclizumab has been approved for acute transplant rejection and commercialized by Hoffmann La-Roche (Roche) under the trademark Zenapax.
 
Volociximab (M200).  Volociximab is a chimeric monoclonal antibody that inhibits the functional activity of α5ß1 integrin, a protein found on activated endothelial cells. Blocking the activity of α5ß1 integrin has been found to prevent angiogenesis, which is the formation of new blood vessels that feed tumors and allow them to grow and metastasize.
 
Elotuzumab (HuLuc63).  Elotuzumab is a humanized monoclonal antibody that binds to CS1, a cell surface glycoprotein that is highly expressed on myeloma cells but minimally expressed on normal human cells.
 
PDL192.  PDL192 is a humanized monoclonal antibody that binds to the TWEAK (tumor necrosis factor-like weak inducer of apoptosis) receptor (TweakR), also known as Fn14 or TNFRSF12A, a cell surface glycoprotein with homology to the family of tumor necrosis factor (TNF) receptors.
 
PDL241.  PDL241 is a novel humanized monoclonal antibody that the Company believes may have potential in immunologic diseases.
 
Trubion Collaboration.  On August 27, 2009, the Company entered into a Collaboration and License Agreement with Trubion (the “Trubion Collaboration”), for the global development and commercialization of protein therapeutics directed at the CD37 antigen, including TRU-016, a CD37-directed small modular immunopharmaceutical, which is in phase 1 clinical trials for chronic lymphocytic leukemia (CLL). The collaboration agreement provides for an upfront cash payment to Trubion of $20 million, and Trubion could receive additional payments from the Company of up to $176.5 million in development, regulatory and sales milestones for each product under the collaboration agreement, the significant majority of which are for achievement of later-stage development, regulatory and sales-based milestones. The Company and Trubion would each fund 50% of the worldwide development and commercialization costs of protein products included in the collaboration and would equally share profits on worldwide sales of products for which they share the development and commercialization costs. The Company and Trubion also entered into a related Stock Purchase Agreement pursuant to which, on September 1, 2009, the Company purchased from Trubion an approximate 11% interest in Trubion for a purchase price of $10 million.
 
Preferred Stock Purchase Rights.  The following description of the Rights is based solely upon publicly available documents filed by the Company with the SEC. This description does not purport to be complete and is qualified in its entirety by reference to the Rights Agreement between the Company and Mellon Investor Services LLC, as Rights Agent, dated as of September 7, 2009 (the “Rights Agreement”), which is filed as Exhibit 4.1 to the Company’s Current Report on Form 8-K filed with the SEC on September 9, 2009, and any subsequent amendments thereto.
 
The Company entered into the Rights Agreement on September 7, 2009 pursuant to which the Company Board declared a dividend of one Right for each outstanding share of Company common stock, to be made as of September 21, 2009 (the “Record Date”). Each Right entitles the registered holder to purchase from the Company, initially, one one-thousandth of a share of preferred stock, at a price of $50, subject to adjustment. The Rights will expire upon the earlier of September 6, 2010 or the redemption or exchange of the Rights by the Company.
 
The Rights become exercisable upon the earlier to occur of the close of business on: (i) the 10th day following (x) the first date of public announcement by the Company or by a person or group of affiliated or associated persons that the person or group of affiliated or associated persons has become the beneficial owner, without approval of the Company Board, of securities of the Company representing 15% or more of the outstanding shares of Company common stock (an “Acquiring Person”), subject to certain exceptions as set forth in the Rights Agreement, or (y) such earlier date as a majority of the Company Board shall become aware of such acquisition of shares of Company common stock (the earlier of (x) or (y), the “Stock Acquisition Date”) (or, if the 10th day after the Stock Acquisition Date occurs before the Record Date, the close of business on the Record Date) or (ii) the 10th business day (or such later date as may be determined by action of the Company Board prior to such time as any person becomes an Acquiring Person) after the date of commencement by any person (other than certain exempt persons)


15


Table of Contents

of, or the first public announcement of the intent of any person (other than certain exempt persons) to commence, a tender or exchange offer upon the successful consummation of which any person would be an Acquiring Person (irrespective of whether any shares are actually purchased pursuant to any such offer) (including any such date which is after the date of the Rights Agreement and prior to the issuance of the Rights; the earlier of such dates being called the “Distribution Date”). Until the Distribution Date, the Rights will be evidenced by the shares of Company common stock with which they are associated and will be transferred with and only with such shares.
 
Absent action by the Company Board, the announcement or commencement of the Offer would result in a distribution of the Rights 10 business days following such announcement or commencement, with no further action from any party.
 
The Rights have a “flip-in” provision that is triggered when a person becomes an Acquiring Person (a “Flip-In Event”). Upon the first occurrence of a Flip-In Event, each Right entitles its holder to purchase a number of shares of Company common stock having a then current market value equal to the exercise price of the Right divided by one-half of the average of the daily closing prices per share of Company common stock for the 30 consecutive trading days prior to the date of the Flip-In Event. Rights owned by any person who becomes an Acquiring Person will become null and void.
 
The Rights also have a “flip-over” provision which specifies that if, following the first occurrence of a Flip-In Event, directly or indirectly, (x) the Company consolidates or merges with and into any other person and the Company is not the surviving or continuing person of such consolidation or merger, or (y) any person consolidates with, or merges with and into the Company and the Company is the continuing or surviving person of such consolidation or merger and, in connection with such consolidation or merger, all or part of the outstanding shares of Company common stock shall be changed into or exchanged for stock or other securities of any other person or of the Company or cash or any other property, or (z) the Company or one or more of its subsidiaries sells, mortgages or otherwise transfers to any other person, in one transaction, or a series of related transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its subsidiaries (taken as a whole), then, on the first occurrence of any such event, proper provision shall be made so that each holder of a Right (other than an Acquiring Person, or affiliates or associates thereof) will thereafter have the right to receive, upon exercise of the Right, that number of shares of common stock of the acquiring company having a market value at the time of such transaction equal to the exercise price of the Right divided by one-half of the average of the daily closing prices per share of common stock of the acquiring company for the 30 consecutive trading days prior to such event.
 
At any time until the occurrence of a Flip-In Event, the Company Board may redeem the Rights in whole, but not in part, for $0.001 per Right. At any time after the occurrence of a Flip-In Event and prior to the earlier of a Flip-Over Event or such time as any person becomes the beneficial owner of more than 50% of the Company common stock outstanding, the Company Board may exchange the Rights, in whole or in part, for shares of Company common stock at an exchange ratio of one share of Company common stock or one one-thousandth of a share of Preferred stock (or of a share of a class or series of preferred stock of the Company having equivalent rights, preferences and privileges) per Right.
 
We believe that if the Rights Condition is satisfied, the Rights Agreement will not be an impediment to consummating either the Offer or the Proposed Merger. However, unless and until the Rights Condition is satisfied, the existence of the Rights has the practical effect of precluding Biogen Idec and Purchaser from consummating the Offer, regardless of the extent to which the Company’s stockholders wish to sell their Shares pursuant to the Offer. Prior to the Distribution Date, a tender of shares of Company common stock will include a tender of the associated Rights. Following the Distribution Date, if any, you will need to tender one Right with each share of Company common stock tendered. We will not pay any additional consideration for the tender of a Right.

Except for the foregoing and except as set forth below or elsewhere in this offer to purchase (including “The Offer — Background of the Offer; Other Transactions with the Company” and “The Offer — Certain Information Concerning the Company”) or Schedule I to this offer to purchase: (i) none of Biogen Idec, Purchaser or, to Biogen Idec’s and Purchaser’s knowledge, the persons listed in Schedule I hereto or any associate or majority-owned subsidiary of Biogen Idec, Purchaser or of any of the persons so listed, beneficially owns or has a right to acquire any Shares or any other equity securities of the Company; (ii) none of Biogen Idec, Purchaser or, to Biogen Idec’s and Purchaser’s knowledge, the persons or entities referred to in clause (i) above has effected any transaction in the Shares or any other equity securities of the Company during the past 60 days; (iii) none of Biogen Idec, Purchaser or, to Biogen Idec’s and Purchaser’s knowledge, the persons listed in Schedule I to this offer to purchase, has any contract, arrangement, understanding or relationship with any other person with respect to any securities of the Company (including, but not limited to, any contract, arrangement, understanding or relationship concerning the

Collaborative Agreement with the Company and Related Matters.  In August 2005, Biogen Idec, through its wholly owned subsidiary Biogen Idec MA Inc. (“BIMA”), entered into a collaborative agreement with PDL for the joint development, manufacture and commercialization of three Phase 2 antibody products. Since the spin-off of the Company from PDL in December 2008, this agreement has resided with the Company. The collaborative agreement provides for Biogen Idec and the Company to share in the development and commercialization of daclizumab in multiple sclerosis and indications other than transplant and respiratory diseases, and the development and commercialization of M200, or volociximab, and HuZAF, or fontolizumab, in all indications. Joint development of fontolizumab by the Company and Biogen Idec was discontinued during 2006. The agreement further provides that both companies will share equally the costs of all development activities and all operating profits from each collaboration product within the U.S. and Europe. In 2005, Biogen Idec paid PDL a non-refundable upfront licensing fee of $40.0 million for these product candidates. The terms of the collaborative agreement require Biogen Idec to make certain development and commercialization milestone payments upon the achievement of certain program objectives totaling up to $660.0 million over the life of the agreement, of which $560.0 million relates to development, and $100.0 million relates to the commercialization of collaboration products. On August 3, 2009, the Company publicly announced the Company’s and our joint decision to continue planning for the phase 3 trial of daclizumab high-yield process in multiple sclerosis and plan to request a Special Protocol Assessment with the U.S. Food and Drug Administration (the “FDA”) prior to the initiation of this phase 3 study. From time to time during the course of the collaboration, Biogen Idec and the Company have discussed revisions to the collaborative agreement and may do so in the future.
 
In addition to the collaborative agreement, in August 2005, Biogen Idec purchased approximately $100.0 million of common stock from PDL, which Biogen Idec subsequently sold in its entirety in 2007.
 
In January 2008, BIMA and PDL entered into an exclusive worldwide licensing agreement involving M200 for the treatment of age-related macular degeneration with Ophthotech Corporation, a privately held biopharmaceutical company focused on developing ophthalmic therapies. Since the spin-off of the Company from PDL, this agreement has resided with the Company.
 
Other Transactions.  Faheem Hasnain, the Company’s Chief Executive Officer, and Ted Llana, the Company’s Senior Vice President, Commercial and Corporate Development, were formerly members of management of Biogen Idec. Each of them received a lump sum payment from Biogen Idec in 2008 in connection with the termination of his employment, determined with reference to his base salary as well as certain bonus amounts. Upon termination of their employment, all unvested equity awards held by Mr. Hasnain or Mr. Llana reverted to Biogen Idec and vested awards continued to be exercisable in accordance with the terms of the applicable stock plan. During the term of employment with Biogen Idec, Mr. Hasnain and Mr. Llana received salary, bonus and other employment benefits commensurate with similarly situated employees of Biogen Idec.
 
Available Information.  Biogen Idec is subject to the informational requirements of the Exchange Act and in accordance therewith files periodic reports, proxy statements and other information with the SEC relating to its business, financial condition and other matters. Biogen Idec is required to disclose in such proxy statements certain information, as of particular dates, concerning its directors and officers, their remuneration, stock options granted to them, the principal holders of its securities and any material interests of such persons in transactions with Biogen Idec.

10.   Source and Amount of Funds.
 
Purchaser estimates that the total amount of funds required to acquire the outstanding Shares pursuant to the Offer and Proposed Merger and to pay related fees and expenses will be approximately $375 million. In order to fund the purchase of all of the Shares pursuant to our Offer and the Proposed Merger and pay fees and expenses related to the transactions, Biogen Idec plans to use its available cash.
 
11.   Background of the Offer; Other Transactions with the Company.
 
During the course of early and mid-2009, the board of directors of Biogen Idec (the “Biogen Idec Board”) continued its efforts to utilize Biogen Idec’s significant cash position to enhance shareholder value through potential acquisitions and other strategic initiatives. In mid-August 2009, the Transaction Committee of the Biogen Idec Board, which had been formed to assist the board by providing oversight of Biogen Idec’s corporate development, business development and new ventures transaction activities, discussed with members of Biogen Idec management and advisors the existing collaborative efforts between Biogen Idec and the Company on the drugs daclizumab and volociximab (see “The Offer — Certain Information Concerning Purchaser and Biogen Idec — Collaborative Agreement with the Company and Related Matters”) and concurred with management’s recommendation to propose to the Company various alternatives to further the efficient development of these products, including combining the two companies.
 
Early the following week, James Mullen, the Chief Executive Officer of Biogen Idec, contacted Faheem Hasnain, the Chief Executive Officer of the Company, to discuss, among other potential alternatives, the possibility of combining the two companies. Later that week following a meeting of the Biogen Idec Board at which the matter was considered, Mr. Mullen again contacted Mr. Hasnain and conveyed Biogen Idec’s interest in acquiring the Company for $15.00 per Share in cash. Biogen Idec set forth its proposal in a letter delivered to the Company Board the next day. The text of that letter follows:
 
August 21, 2009
 
Facet Biotech Corporation
Board of Directors
c/o Faheem Hasnain, President and Chief Executive Officer
1500 Seaport Boulevard
Redwood City, CA 94063
 
Dear Faheem:
 
This confirms that Biogen Idec Inc. is proposing to acquire all of the outstanding shares of Facet Biotech Corporation for $15.00 per share in cash. Our all-cash offer represents a premium of approximately 53% over the closing price of Facet Biotech’s common stock on August 17, the day we initially discussed our interest in a transaction; a premium of approximately 61% over the one-month average closing price; and a premium of 78% over the average closing price since January 1, 2009.
 
As communicated in yesterday’s phone call, Biogen Idec believes this transaction makes compelling business sense for both of our companies and is in the best interests of our respective shareholders. The price Biogen Idec is offering represents an extremely attractive opportunity for Facet Biotech’s shareholders to realize today the future value of your company. In addition, we believe this transaction will enable the important multiple sclerosis and solid tumor clinical programs which we have been working on in collaboration for nearly four years to have the best chance of reaching the market and improving patients’ lives.
 
Biogen Idec has engaged Leerink Swann LLC as financial advisor and Wachtell, Lipton, Rosen & Katz as legal counsel to assist us in completing this transaction. Our offer would not be subject to approval by the shareholders of Biogen Idec and is not subject to any financing contingency. We do not foresee any regulatory or other impediment to closing. Any definitive transaction documentation will be subject to the approval of our Board of Directors and would contain conditions completely customary for a transaction of this nature. We and our advisors are prepared to meet with you and your advisors to answer any questions you may have about our offer and to commit all necessary resources to complete a transaction expeditiously.

Table of Contents

Our offer assumes, and it is very important to Biogen Idec, that Facet Biotech does not undertake any material commercial or strategic transactions between now and the consummation of this transaction.
 
We would appreciate hearing from you as soon as possible and in any event by 05:00 pm EDT on August 28, 2009. Our strong desire is to conclude a negotiated transaction with you and the Facet Biotech Board of Directors.
 
As is customary, this letter does not constitute a binding commitment. I look forward to hearing from you as soon as possible. If you do not reach me, feel free to call Michael Lytton.
 
Sincerely,

The Company responded to Biogen Idec’s proposal in a letter it delivered to Biogen Idec on August 25, 2009. The text of the Company’s letter follows:
 
August 25, 2009
 
Mr. James C. Mullen
Biogen Idec, Inc.
14 Cambridge Center
Cambridge, MA 02142
 
Dear Jim:
 
We are in receipt of your letter dated August 21, 2009. The Facet Biotech board of directors, with the assistance of its financial and legal advisors, has carefully considered your expression of interest to acquire our Company and has determined that is not in our stockholders’ best interest to pursue such a transaction on the terms you have offered. Our board and management remain firmly committed to increasing the value of the Company to our stockholders. We believe our development programs, our collaborations and our technology capabilities continue to represent substantial potential value for our stockholders.
 
As you well know, net of cash, your offer places negligible value on, among other things: daclizumab, on which our companies have been partnered for four years, and which we recently decided jointly with you to advance into phase 3; our pipeline, which includes multiple products in clinical trials; our protein engineering technologies; and our scientific capabilities.
 
Like any responsible board, we are receptive to opportunities to further enhance stockholder value.
 
Sincerely,
 
/s/ Faheem Hasnain

Table of Contents

On September 4, 2009, after further contacts by representatives of Biogen Idec seeking to engage the Company in exploring a negotiated transaction, Biogen Idec delivered a letter to the Company Board containing a revised proposal to acquire all of the outstanding Shares for $14.50 per Share in cash and publicly announced that it had made the proposal. The full text of the September 4, 2009 letter to the Company Board follows:
 
September 4, 2009
 
Facet Biotech Corporation
Board of Directors
c/o Faheem Hasnain, President and Chief Executive Officer
1500 Seaport Boulevard
Redwood City, CA 94063
 
Dear Faheem:
 
We are deeply disappointed Facet chose to announce a collaboration with Trubion on the day you and I were scheduled to discuss Biogen Idec’s all-cash proposal to acquire Facet, which you rejected on August 25.
 
Moreover, the timing of the Trubion collaboration follows a sequence of events that suggest you have no interest in having a bona fide discussion with us about a combination of our two companies. As we have stated, we believe such a combination makes compelling business sense for both of our companies and is in the best interests of our respective shareholders.
 
  •  On August 17, you and I spoke and I proposed various alternatives to working together including combining our two companies. On that call, we agreed to speak again later that week.
 
  •  On August 20, you and I spoke and I conveyed Biogen Idec’s interest in acquiring Facet for $15 per share in cash.
 
  •  On August 21, I sent a letter to you and Facet’s Board of Directors stating Biogen Idec’s proposal to purchase Facet for $15 per share in cash. Our letter included the statement that “our offer assumes, and it is very important to Biogen Idec, that Facet does not undertake any material commercial or strategic transactions between now and the consummation of this transaction,” which reiterated what I communicated to you on our August 17 phone call. The Trubion collaboration is an example of such a transaction.
 
  •  On August 25, you sent us a response rejecting our proposal and suggested we speak on August 28. Notwithstanding that agreement to speak, Facet announced the collaboration with Trubion prior to our call.
 
Accordingly, we have decided to disclose publicly our interest in pursuing a business combination with Facet. We believe your collaboration with Trubion reduces Facet’s value, as apparently do Facet’s investors, as evidenced by the 22% reduction in Facet’s stock price since announcing the Trubion collaboration. As a result, we are lowering the price we are offering to acquire Facet.
 
We are proposing to acquire Facet for $14.50 per share in cash, which represents a premium of approximately 64% over the closing price of Facet’s common stock on September 3, 2009.
 
The price Biogen Idec is proposing represents an extremely attractive opportunity for Facet’s shareholders to realize today the future value of your company. In addition, we believe this transaction will enable the important multiple sclerosis and solid tumor clinical programs that we have been working on in collaboration for nearly four years to have the best chance of reaching the market and improving patients’ lives.
 
Biogen Idec has engaged Leerink Swann LLC as financial advisor and Wachtell, Lipton, Rosen & Katz as legal counsel to assist us in completing this transaction. Our offer would not be subject to approval by the shareholders of Biogen Idec and is not subject to any financing contingency. We do not foresee any regulatory or other impediment to closing. Any definitive transaction documentation will be subject to the approval of our Board of Directors and would contain conditions completely customary for a transaction of this nature.
 
We and our advisors are prepared to meet with you and your advisors to answer any questions you may have about our offer. We would like to complete a transaction expeditiously and we are prepared to commit all necessary resources to achieve this goal.

The Company responded to Biogen Idec’s proposal by letter dated September 8, 2009. The text of that letter follows:
 
September 8, 2009
 
Mr. James C. Mullen
Biogen Idec Inc.
14 Cambridge Center
Cambridge, MA 02142
 
Dear Jim:
 
We are in receipt of your letter dated September 4, 2009.
 
Facet Biotech’s board of directors, with assistance from its financial and legal advisors, has reviewed your revised proposal to acquire our company for $14.50 per share. After careful consideration, we have determined that it is not in our stockholders’ best interests to pursue a transaction under the terms you have proposed, and we therefore reject your proposal.
 
As we stated in our response to your proposal of $15 per share on August 21, we believe your proposal does not reflect Facet Biotech’s existing value or our long-term ability to create value for our stockholders. We reject your revised proposal because, among other reasons, we believe that:
 
  •  The proposal values Facet Biotech at approximately the value of its cash, marketable securities and restricted cash ($371.1 million as of June 30, 2009, or approximately $15.11 per share based on shares outstanding as of July 31, 2009) and thus places no value on the operating and other assets of the company.
 
  •  Daclizumab represents substantial value for the company and our stockholders. This is based on the daclizumab data seen to date over multiple clinical trials, the insights that both Facet Biotech and Biogen Idec have on the development program, as well as the significant market opportunity in multiple sclerosis. This belief is reinforced by the recent decision by Facet Biotech and Biogen Idec to advance the program into a phase 3 trial. Biogen Idec’s enthusiasm for the daclizumab program is evident from the sizeable investment being made to fund its part of the collaboration to move into phase 3, including a $30 million milestone payment due to Facet Biotech from Biogen Idec upon the enrollment of the first patient in the trial, which is expected in the first half of 2010.
 
  •  The proposal does not reflect the value of Facet Biotech’s pipeline of four additional programs in clinical development and one in preclinical development, the company’s protein engineering technologies or our scientific capabilities. In addition to the $30 million milestone payment related to daclizumab, Facet Biotech has the potential to earn from Bristol-Myers Squibb Company an additional $30 million in milestone payments by the first half of 2010 related to two of these other programs.
 
  •  The proposal does not reflect the value of the strategic fit with Biogen Idec or the substantial synergies that Biogen Idec, or any number of potential acquirers, could attain from an acquisition of Facet Biotech.
 
Additionally, despite your suggestions otherwise, we do not believe our collaboration with Trubion is in any way adverse to the valuation of, or your interest in, our company. I believe you are aware that I attempted to contact you on Tuesday, August 25 prior to the signing of the Trubion collaboration but was told by your office that you were not available because of your travel schedule until Friday the 28th. As I discussed with you on the 28th, we had been working on the Trubion transaction for some time, and our announcement did not reflect any attempt to impede a transaction with Biogen Idec. We entered into the Trubion collaboration only

after concluding that it was a positive for our stockholders and was likely to be a positive synergistic opportunity for Biogen Idec as well.
 
Our board of directors and management team continue to take our fiduciary responsibilities to our stockholders extremely seriously. We remain committed to building value for all our stockholders and remain open to opportunities at any time that will help us achieve that.
 
Sincerely,
 
/s/ Faheem Hasnain
President and Chief Executive Officer
Facet Biotech Corporation
 
On September 8, Mr. Mullen spoke to Mr. Hasnain. Mr. Mullen indicated he understood that Mr. Hasnain believes there is additional value in Facet Biotech and expressed a willingness for Biogen Idec to enter into a confidentiality agreement with Facet Biotech so that Facet Biotech could provide information demonstrating that value. Mr. Hasnain indicated Facet Biotech was unwilling to do so based on the terms of Biogen Idec’s proposal.
 
On September 21, 2009, Purchaser commenced the Offer and Biogen Idec delivered the following letter to the Company Board:
 
September 21, 2009
 
Facet Biotech Corporation
Board of Directors
c/o Faheem Hasnain, President and Chief Executive Officer
1500 Seaport Boulevard
Redwood City, CA 94063
 
Dear Faheem:
 
Biogen Idec is today commencing a tender offer to acquire all of the outstanding shares of Facet Biotech Corporation for $14.50 per share in cash. As you know, we have repeatedly expressed our interest in discussing with Facet Biotech’s Board of Directors and management team the potential acquisition of Facet Biotech by Biogen Idec in a negotiated transaction, but have been told that Facet Biotech has no interest in discussing a potential transaction on the terms we proposed. In light of the rejection of the proposal by Facet Biotech’s Board of Directors on September 8, 2009, we are presenting our $14.50 per share, all-cash offer directly to Facet Biotech’s stockholders.
 
In commencing this tender offer, we would like to address for the record certain of the assertions you made through the September 8, 2009 letter and press release rejecting our offer, as well as in subsequent communications to the investment community.
 
First, Facet Biotech has stated inaccurately that Biogen Idec’s $14.50 per share proposal “represents only the cash on [Facet Biotech’s] balance sheet and fails to attribute any value to daclizumab, or to the rest of [Facet Biotech’s] R&D pipeline and platform.” Specifically, Facet Biotech asserts that its cash balance as of June 30, 2009 represents a per share cash value of approximately $15.11. In fact, Facet Biotech’s available cash is considerably below our offer price of $14.50 per share when the following factors are accounted for:
 
  •  In public statements, Facet Biotech has estimated that it will use approximately $80 million in cash in 2009 and indicated that about $32 million had already been spent through June 30, 2009. This implies that the monthly cash usage is about $8 million for the rest of 2009. Each month that passes is another month in which Facet Biotech’s cash balance decreases.
 
  •  Facet Biotech also recently spent $30 million in cash as part of its Trubion collaboration, in addition to committing to funding future development costs and milestone payments, which it has since confirmed are not included in its estimated $80 million per year cash expenditure rate. This new collaboration obligation represents a significant cash burden to Facet Biotech.

  •  Facet Biotech also has significant lease and other obligations. As you recently disclosed, Facet Biotech has total lease obligations on an undiscounted basis of approximately $208 million. Facet Biotech’s most recent Quarterly Report discloses additional obligations totaling over $12 million related to manufacturing, post-retirement benefits, and other obligations.
 
  •  Facet Biotech has referred to its cash per share using shares outstanding as of July 31, 2009, but this overstates the amount because it does not reflect the shares underlying outstanding options.
 
When these factors are included in the per share cash analysis, the available cash is significantly below the reported June 30, 2009 balance.
 
Second, Facet Biotech claims that Biogen Idec’s proposal does not reflect the value of daclizumab, additional programs in its pipeline, its technology platform, related milestone payments, and synergies. However, the fact that Facet Biotech’s net cash per share is considerably below our offer price means that Biogen Idec’s proposal does ascribe meaningful value for these operating assets. Further, Biogen Idec’s $14.50 offer represents a 64% premium over the $8.82 per share closing price of Facet Biotech on September 3, 2009.
 
Third, Facet Biotech suggests that “the significance of the [interim futility analysis regarding daclizumab] has not been fully appreciated by the investment community.” In fact, Facet Biotech’s stock price increased approximately 13% on the day following the announcement regarding the interim futility analysis and 27% from that day to the day prior to the announcement of the Trubion collaboration, evidencing a significant appreciation for the futility analysis findings in the market.
 
Fourth, Facet Biotech suggests that it only entered into the Trubion collaboration “after concluding that it was a positive for [Facet’s] stockholders and was likely to be a positive synergistic opportunity for Biogen Idec as well.” We believe that our view that the Trubion collaboration is value destructive has been corroborated by the fact that Facet Biotech’s stock price dropped 22% in the five trading days following the announcement of the Trubion collaboration and prior to Biogen Idec’s proposal.
 
Finally, Facet Biotech has disclosed that it expects its cash balance to be completely depleted by the end of 2012, despite the fact that the company will have significant remaining obligations and the need to continue funding its clinical programs, including importantly, the clinical programs in which it is partnered with Biogen Idec.
 
Biogen Idec’s proposal represents an extremely attractive opportunity for Facet Biotech’s shareholders to receive today the future value of the company. We continue to urge you to engage in discussions with us so that we may reach a definitive merger agreement.
 
Sincerely,
 
/s/ James C. Mullen
President and Chief Executive Officer
 
12.   Purpose and Structure of the Offer; Plans for the Company.
 
Purpose of the Offer.  The purpose of the Offer and the Proposed Merger is for Biogen Idec to acquire control of, and the entire equity interest in, the Company. The Offer is the first step in the acquisition of the Company. The purpose of the Proposed Merger is to acquire all of the outstanding Shares not tendered and purchased pursuant to the Offer. If the Offer is successful, we intend to consummate the Proposed Merger as promptly as practicable.
 
Biogen Idec previously made a proposal to the Company to acquire all the outstanding Shares for $14.50 per Share in cash, which followed an earlier proposal to acquire all of the outstanding shares for $15.00 per Share in cash. See “The Offer — Background of the Offer; Other Transactions with the Company.” The Company Board rejected each of those proposals and refused to meet with Biogen Idec to discuss a business combination of the two companies. Biogen Idec, through Purchaser, is making this Offer directly to the Company’s stockholders. However, there are substantial conditions to consummation of the Offer, among them the Minimum Condition, the Section 203 Condition, the Regulatory Condition, the Rights Condition and the Impairment Condition. If the Company Board


24


Table of Contents

opposes the Offer, certain provisions of the Delaware General Corporation Law and of the Company’s Rights Agreement would affect Purchaser’s ability to obtain control of the Company and to effect the Proposed Merger. In addition, there can be no assurance that the conditions to consummation of the Offer will be satisfied. Therefore, there can be no assurance that Purchaser will be able to consummate the Offer or, if the Offer is consummated, that Purchaser will be able to effectuate the Proposed Merger, nor can there be any guarantee as to the timing of the Proposed Merger if it is consummated. See below and the section entitled “The Offer — Conditions to the Offer” for more information.
 
Company Board and Stockholder Approval.  The timing and details of the consummation of the Offer and the Proposed Merger depend on a variety of factors and legal requirements, the number of Shares (if any) acquired by Purchaser pursuant to the Offer, and importantly, actions of the Company Board. In general (other than with respect to short-form mergers described below), under the Delaware General Corporation Law, the approval of both the stockholders and the board of directors of a corporation is required to effect a merger of that corporation with or into another corporation. Unless Purchaser acquires more than 90% of the then outstanding Shares through the Offer or otherwise, the Proposed Merger can be effected only with the approval of the Company Board and the affirmative vote of the holders of at least a majority of the outstanding shares. If the Minimum Condition, the Section 203 Condition, the Rights Condition and the other conditions to the Offer discussed in the Introduction and section entitled “The Offer — Conditions to the Offer” are satisfied, Purchaser will own Shares representing at least a majority of the outstanding Shares after consummation of the Offer, and will have the voting power necessary to assure approval of the Proposed Merger by the Company’s stockholders in the event that a majority of the members of the Company Board have determined to submit the Proposed Merger for stockholder approval. Although Purchaser will seek to have the Company consummate the Proposed Merger as soon as practicable after consummation of the Offer, because the Proposed Merger must be approved by the Company Board, the Proposed Merger could be delayed for a substantial period of time if the Company Board refuses to approve the Proposed Merger, including through the next annual meeting of stockholders of the Company at which all of the Company’s directors would stand for reelection. In this event, Biogen Idec anticipates it could be necessary to solicit proxies for the election of some number of its own nominees to the Company Board at the 2010 annual meeting of Company stockholders, in order to enhance its ability to effect the Proposed Merger. However, irrespective of the outcome of any such proxy solicitation, there can be no assurance that a majority of the members of the Company Board would approve the Proposed Merger.
 
Short-Form Merger.  Under Section 253 of the Delaware General Corporation Law, if a corporation owns at least 90% of the outstanding shares of each class of a subsidiary corporation, the corporation holding such stock may merge such subsidiary into itself or itself into such subsidiary, without any action or vote on the part of the board of directors or stockholders of such other corporation (a “short-form merger”). If Purchaser acquires, pursuant to the Offer or otherwise, at least 90% of the outstanding Shares (where the conditions in “The Offer — Conditions to the Offer,” including the Section 203 Condition and the Rights Condition, have been satisfied), Purchaser will be able to effect the Proposed Merger without a vote of the Company’s stockholders. Undertaking a short-form merger generally will permit stockholders receiving consideration pursuant to the Merger to receive such consideration more promptly than in a merger in which a stockholder vote is required (assuming all other conditions have already been met).
 
The satisfaction of several of the principal conditions to the Offer is within the control of the Company Board, including the Section 203 Condition, the Rights Condition and the Impairment Condition. Biogen Idec and Purchaser believe that, to the extent possible, the Company Board should take all necessary actions to facilitate consummation of the Offer and hereby request that they do so. Unless the Company Board acts to facilitate consummation of the Offer, Purchaser will not be able to consummate the Offer. Biogen Idec and Purchaser currently intend to pursue the Proposed Merger following consummation of the Offer. We reserve the right, however, not to pursue the Proposed Merger at all, to amend the terms of the Proposed Merger, or to pursue an alternative second-step business combination transaction involving the Company in which the Shares not owned by Biogen Idec or its affiliates would be converted into securities or other consideration, or exchanged for cash.
 
Plans for the Company.  In connection with this Offer, Biogen Idec has reviewed and will continue to review various possible business strategies that it might consider in the event that Purchaser acquires control of the Company, whether pursuant to the Offer, the Proposed Merger or otherwise. Following review of additional

Table of Contents

information regarding the Company, such strategies may involve, among other things, changes in the Company’s business, operations, corporate structure, capitalization and management.
 
13.   Effect of the Offer on the Market for the Common Stock; Registration under the Exchange Act.
 
Reduced Liquidity; Possible Delisting.  The purchase of Shares pursuant to the Offer will reduce the number of holders of the Shares and the number of Shares that might otherwise trade publicly and could adversely affect the liquidity and market value of the remaining Shares held by the public. The Shares are listed and principally traded on the Nasdaq Market. Depending on the number of Shares acquired pursuant to the Offer, following consummation of the Offer, the Shares may no longer meet the requirements of Nasdaq for continued listing on the Nasdaq Market. According to Nasdaq’s published guidelines, Nasdaq would consider delisting the Shares if, among other things, (1) the total number of holders of Shares falls below 400; (2) the Shares fail to maintain a minimum bid price of $1.00 per Share; and (3) neither of the following continued listing requirements is met: (a) the number of publicly held Shares (exclusive of Shares held by officers, directors and 10% or greater stockholders) is at least 750,000, the market value of the publicly held Shares totals at least $5 million, there are at least two registered and active market makers in the Shares and the Company’s stockholders’ equity remains at least $10 million or (b) the number of publicly held Shares is at least 1,100,000, the market value of the publicly held Shares totals at least $15 million, there are at least four registered and active market makers in the Shares and either the market value of the Company’s listed Shares remains at least $50 million or the Company’s total assets and total revenue are at least $50 million each for the most recently completed fiscal year or two of the three most recently completed fiscal years.
 
If Nasdaq were to delist the Shares, the market for the Shares could be adversely affected. It is possible that the Shares would be traded on other securities exchanges or in the over-the-counter market and that price quotations would be reported by such exchanges, or by other sources. The extent of the public market for the Shares and the availability of such quotations would, however, depend upon the number of holders and/or the aggregate market value of the Shares remaining at such time, the interest in maintaining a market in the Shares on the part of securities firms, the possible termination of registration of the Shares under the Exchange Act, as described below, and other factors.
 
Status as “Margin Securities.” The Shares are presently “margin securities” under the regulations of the Federal Reserve Board, which has the effect, among other things, of allowing brokers to extend credit on the collateral of the Shares. Depending on the factors similar to those described above with respect to listing and market quotations, following consummation of the Offer, the Shares may no longer constitute “margin securities” for the purposes of the Federal Reserve Board’s margin regulations, in which event the Shares would be ineligible as collateral for margin loans made by brokers.
 
Registration under the Exchange Act.  The Shares are currently registered under the Exchange Act. The Company can terminate that registration upon application to the SEC if the outstanding Shares are not listed on a national securities exchange and if there are fewer than 300 holders of record of the Shares. Termination of registration of the Shares under the Exchange Act would reduce the information that the Company must furnish to its stockholders and to the SEC and would make certain provisions of the Exchange Act, such as the short-swing profit recovery provisions of Section 16(b) and the requirement of furnishing a proxy statement in connection with stockholders’ meetings pursuant to Section 14(a) and the related requirement of furnishing an annual report to stockholders, no longer applicable with respect to the Shares. If registration of the Shares under the Exchange Act were to be terminated, the Shares would no longer be eligible for Nasdaq listing or for continued inclusion on the Federal Reserve Board’s list of “margin securities.”
 
14.   Dividends and Distributions.
 
If, on or after the date of this offer to purchase, the Company should split, combine or otherwise change the Shares or its capitalization, acquire or otherwise cause a reduction in the number of outstanding Shares, or issue or sell any additional Shares (other than Shares issued pursuant to and in accordance with the terms in effect on the date of this offer to purchase of employee stock options outstanding prior to such date), shares of any other class or series of capital stock, other voting securities or any securities convertible into, or options, rights or warrants, conditional

Table of Contents

or otherwise, to acquire, any of the foregoing, then, without prejudice to our rights under “The Offer — Conditions to the Offer,” we may, in our sole discretion, make such adjustments in the purchase price and other terms of the Offer as we deem appropriate, including the number or type of securities to be purchased.
 
If, on or after the date of this offer to purchase, the Company should declare or pay any dividend on the Shares or make any distribution with respect to the Shares (including the issuance of additional Shares or other securities or rights to purchase any securities) that is payable or distributable to stockholders of record on a date prior to the transfer to the name of Purchaser or its nominee or transferee on the Company’s stock transfer records of the Shares purchased pursuant to the Offer, then, without prejudice to our rights under the Section entitled “The Offer — Conditions to the Offer,” (i) the purchase price per Share payable by us pursuant to the Offer will be reduced to the extent of any such cash dividend or distribution and (ii) the whole of any such non-cash dividend or distribution to be received by the tendering stockholders will (a) be received and held by the tendering stockholders for our account and will be required to be promptly remitted and transferred by each tendering stockholder to the Depositary for our account, accompanied by appropriate documentation of transfer or (b) at our direction, be exercised for our benefit, in which case the proceeds of such exercise will promptly be remitted to us. Pending such remittance and subject to applicable law, we will be entitled to all rights and privileges as owner of any such non-cash dividend or distribution, issuance or proceeds thereof and may withhold the entire purchase price or deduct from the purchase price the amount or value thereof, as determined by us in our sole discretion.
 
15.   Conditions to the Offer.
 
Notwithstanding any other provision of the Offer, and in addition to (and not in limitation of) our rights to extend and amend the Offer at any time, we are not required to accept for payment or, subject to any applicable rules and regulations of the SEC (including those relating to Purchaser’s obligation to pay for or return Shares promptly after termination or withdrawal of the Offer), pay for, and may delay the acceptance for payment of and accordingly the payment for, any tendered Shares, and we may terminate the Offer, if (1) on or prior to the Expiration Date, any one or more of the Minimum Condition, the Section 203 Condition, the Regulatory Condition, the Rights Condition or the Impairment Condition have not been satisfied or (2) at any time on or after the date of this offer to purchase and prior to the Expiration Date, any of the following events or conditions shall occur or exist:

of the outstanding Shares, in each case other than ownership by any person or group to the extent that such ownership has been disclosed prior to the date of commencement of the Offer in a Schedule 13D or Schedule 13G on file with the SEC, and no such person (other than Biogen Idec, Purchaser, any of their affiliates, or any group of which any of them is a member) or group that had so filed such a Schedule with the SEC shall have increased or publicly proposed to increase its beneficial ownership in the Company by more than 1% of the outstanding Shares, or shall have been granted any right, option or warrant, conditional or otherwise, to acquire beneficial ownership of an additional 1% or more of the outstanding Shares, or shall have filed a Notification and Report Form under the HSR Act or made a public announcement reflecting an intent to acquire the Company or any of its subsidiaries or material assets of the Company;

which, in any such case, and regardless of the circumstances (including any action or inaction by Biogen Idec or Purchaser or any of their affiliates) giving rise to any such condition, makes it inadvisable to proceed with the Offer or with such acceptance of Shares for payment.
 
The foregoing conditions are for the sole benefit of Biogen Idec and Purchaser and may be asserted by Biogen Idec or Purchaser regardless of the circumstances giving rise to any such condition, in their sole discretion, or, subject to the Offer remaining open for any minimum period following waiver of a material condition as required by SEC rules and regulations, may be waived by Biogen Idec or Purchaser in whole or in part at any time and from time to time in their sole discretion. To the extent permitted by the rules and regulations of the SEC, the failure by Biogen Idec or Purchaser at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right; the waiver of any such right with respect to particular facts and other circumstances shall not be deemed a waiver


30


Table of Contents

with respect to any other facts and circumstances; and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time.
 
16.   Certain Legal Matters; Regulatory Approvals.
 
General.  We are not aware of any governmental license or regulatory permit that appears to be material to the Company’s business that might be adversely affected by our acquisition of Shares pursuant to the Offer or, except as set forth below, of any approval or other action by any government or governmental administrative or regulatory authority or agency, domestic or foreign, that would be required for our acquisition or ownership of Shares pursuant to the Offer. Should any such approval or other action be required, we currently contemplate that such approval or other action will be sought. There can be no assurance that any such approval or other action, if needed, would be obtained (with or without substantial conditions) or that if such approvals were not obtained or such other actions were not taken, adverse consequences might not result to the Company’s business or certain parts of the Company’s, Biogen Idec’s, Purchaser’s or any of their respective subsidiaries’ businesses might not have to be disposed of or held separate, any of which could cause us to elect to terminate the Offer without the purchase of Shares thereunder. Our obligation under the Offer to accept for payment and pay for Shares is subject to certain conditions. See “The Offer — Conditions to the Offer.”
 
State Takeover Laws.  The Company is incorporated under the laws of the State of Delaware. In general, Section 203 of the Delaware General Corporation Law prevents an “Interested Stockholder” (including a person who owns or has the right to acquire 15% or more of a corporation’s outstanding voting stock) from engaging in a “Business Combination” (which term includes mergers and certain other actions) with a Delaware corporation for a period of three years following the date such person became an interested stockholder unless, among other things, the transaction which resulted in the stockholder becoming an interested stockholder is approved by the board of directors of such corporation prior to such date.
 
A number of states have adopted laws and regulations that purport to apply to attempts to acquire corporations that are incorporated in such states, or whose business operations have substantial economic effects in such states, or which have substantial assets, security holders, employees, principal executive offices or principal places of business in such states. In 1982, in Edgar v. MITE Corp., the Supreme Court of the United States (the “Supreme Court”) invalidated on constitutional grounds the Illinois Business Takeover statute, which, as a matter of state securities law, made certain corporate acquisitions more difficult. However, in 1987, in CTS Corp. v. Dynamics Corp. of America, the Supreme Court held that the State of Indiana may, as a matter of corporate law and, in particular, with respect to those aspects of corporate law concerning corporate governance, constitutionally disqualify a potential acquiror from voting on the affairs of a target corporation without the prior approval of the remaining stockholders. The state law before the Supreme Court was by its terms applicable only to corporations that had a substantial number of stockholders in the state and were incorporated there.
 
We do not believe that the anti-takeover laws and regulations of any state other than the State of Delaware will by their terms apply to the Offer. We reserve the right to challenge the applicability or validity of any state law purportedly applicable to the Offer and nothing in this offer to purchase or any action taken in connection with the Offer is intended as a waiver of such right. If it is asserted that any state anti-takeover statute is applicable to the Offer and an appropriate court does not determine that it is inapplicable or invalid as applied to the Offer, we might be required to file certain information with, or to receive approvals from, the relevant state authorities, and we might be unable to accept for payment or pay for Shares tendered pursuant to the Offer or may be delayed in consummating the Offer. In any such case, we may not be obligated to accept for payment, or pay for, any Shares tendered pursuant to the Offer.
 
Antitrust.  The Offer and Proposed Merger will require the approval or clearance of certain antitrust agencies. Except as set forth in this Section, Biogen Idec does not have access to the information required to determine whether any material approval or other action by any governmental or administrative agency under applicable antitrust laws is required for the acquisition of Shares in the Offer and the Proposed Merger. Biogen Idec will make any required antitrust filings. Biogen Idec has determined that a filing under the HSR Act will be required.
 
Under the HSR Act, and the rules that have been promulgated thereunder by the Federal Trade Commission (the “FTC”), certain acquisition transactions may not be consummated unless certain information has been


31


Table of Contents

furnished to the Antitrust Division of the Department of Justice (the “Antitrust Division”) and the FTC and certain waiting period requirements have been satisfied. The purchase of Shares pursuant to the Offer is subject to such requirements.
 
Pursuant to the requirements of the HSR Act, Biogen Idec intends to file a Notification and Report Form with respect to the Offer and the Proposed Merger with the Antitrust Division and the FTC. The applicable waiting period will expire at 11:59 p.m., New York City time, 15 calendar days after Biogen Idec’s HSR filing, unless the waiting period ends on a weekend or federal holiday, in which case the waiting period will expire the next business day. However, prior to such time, the Antitrust Division or the FTC may extend the waiting period by requesting additional information or documentary material relevant to the Offer from us. If such a request is made, the waiting period will be extended until 11:59 p.m., New York City time, on the tenth day after our substantial compliance with such request. Thereafter, such waiting period can be extended only by court order or as agreed to by Biogen Idec. A request will be made pursuant to the HSR Act for early termination of the waiting period applicable to the Offer. There can be no assurance, however, that the HSR Act waiting period will be terminated early.
 
Shares will not be accepted for payment or paid for pursuant to the Offer until the expiration or earlier termination of the applicable waiting period under the HSR Act. See “The Offer — Conditions to the Offer.” Subject to certain circumstances described in “The Offer — Extension of Tender Period; Termination; Amendment,” any extension of the waiting period will not give rise to any withdrawal rights not otherwise provided for by applicable law. See “The Offer — Withdrawal Rights.” If our acquisition of Shares is delayed pursuant to a request by the Antitrust Division or the FTC for additional information or documentary material pursuant to the HSR Act, the Offer may be extended.
 
The Antitrust Division and the FTC frequently scrutinize the legality under the antitrust laws of transactions such as our acquisition of Shares pursuant to the Offer. At any time before or after consummation of any such transactions, the Antitrust Division or the FTC could take such action under the antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the purchase of Shares pursuant to the Offer or seeking divestiture of the Shares so acquired or divestiture of Biogen Idec’s or the Company’s material assets. Private parties (including individual states) may also bring legal actions under the antitrust laws. Based on an examination of the publicly available information relating to the businesses in which the Company is engaged, we do not believe that the consummation of the Offer will result in a violation of any applicable antitrust laws. However, there can be no assurance that a challenge to the Offer on antitrust grounds will not be made, or if such a challenge is made, what the result will be. See “The Offer — Conditions to the Offer” for certain conditions to the Offer, including conditions with respect to litigation and certain governmental actions.
 
Appraisal Rights.  You do not have appraisal rights as a result of the Offer. However, if the Proposed Merger is consummated, stockholders of the Company who continue to own Shares after the Offer and who have neither voted in favor of the merger nor consented thereto in writing, who timely submit a demand for appraisal in accordance with the requirements of Section 262 of the Delaware General Corporation Law and who otherwise comply with the applicable statutory procedures under the Delaware General Corporation Law will be entitled to receive a judicial determination of the fair value of their Shares (exclusive of any element of value arising from the accomplishment or expectation of such merger) and to receive payment of such fair value in cash, together with interest compounded quarterly and accruing at 5% over the Federal discount rate (unless a court determines otherwise) (all such Shares collectively, the “Dissenting Shares”). Any such judicial determination of the fair value of the Dissenting Shares could be based upon considerations other than or in addition to the price paid in the Offer and the market value of the Shares. Stockholders should recognize that the value so determined could be higher or lower than, or the same as, the price per Share paid pursuant to the Offer or the consideration paid in such a merger. Moreover, we may argue in an appraisal proceeding that, for purposes of such a proceeding, the fair value of the Dissenting Shares is less than the price paid in the Offer.
 
If any holder of Shares who demands appraisal under Section 262 of the Delaware General Corporation Law fails to perfect, or effectively withdraws or loses his rights to appraisal as provided in the Delaware General Corporation Law, the Shares of such stockholder will be converted into the right to receive the price per Share paid in the Offer. Failure to follow the steps required by Section 262 of the Delaware General Corporation Law for perfecting appraisal rights may result in the loss of such rights.

The foregoing discussion is not a complete statement of the Delaware General Corporation Law and is qualified in its entirety by reference to the Delaware General Corporation Law.
 
Going Private Transactions.  The SEC has adopted Rule 13e-3 under the Exchange Act which is applicable to certain “going private” transactions and which may under certain circumstances be applicable to the Proposed Merger or another business combination following the purchase of Shares pursuant to the Offer in which Purchaser seeks to acquire the remaining Shares not held by it. Purchaser believes, however, that Rule 13e-3 will not be applicable to the Proposed Merger because it is anticipated that the Proposed Merger would be effected within one year following consummation of the Offer and in the Proposed Merger stockholders would receive the same price per Share as paid in the Offer. If Rule 13e-3 were to be applicable to the Proposed Merger, it would require, among other things, that certain financial information concerning the Company, and certain information relating to the fairness of the proposed transaction and the consideration offered to minority stockholders in such a transaction, be filed with the SEC and disclosed to minority stockholders prior to consummation of the transaction. The purchase of a substantial number of Shares pursuant to the Offer may result in the Company being able to terminate its Exchange Act registration, although Purchaser has no current intention to do so prior to the Effective Time. See “The Offer — Effect of the Offer on the Market for the Common Stock; Registration under the Exchange Act.” If such registration were to be terminated, Rule 13e-3 would be inapplicable to any such future Proposed Merger or such alternative transaction.
 
17.   Fees and Expenses.
 
We have retained Innisfree M&A Incorporated as Information Agent in connection with the Offer. The Information Agent may contact holders of Shares by mail, telephone and personal interview and may request brokers, dealers and other nominee stockholders to forward material relating to the Offer to beneficial owners of Shares. We will pay the Information Agent reasonable and customary compensation for these services in addition to reimbursing the Information Agent for its reasonable out-of-pocket expenses. We have agreed to indemnify the Information Agent against certain liabilities and expenses in connection with the Offer, including certain liabilities under the U.S. federal securities laws.
 
We have retained Computershare Trust Company, N.A. as the Depositary. The Depositary has not been retained to make solicitations or recommendations in its role as Depositary. We will pay the Depositary reasonable and customary compensation for its services in connection with the Offer, will reimburse the Depositary for its reasonable out-of-pocket expenses and will indemnify the Depositary against certain liabilities and expenses, including certain liabilities under the U.S. federal securities laws.
 
Except as set forth above, we will not pay any fees or commissions to any broker, dealer or other person for soliciting tenders of Shares pursuant to the Offer. We will reimburse brokers, dealers, commercial banks and trust companies and other nominees, upon request, for customary clerical and mailing expenses incurred by them in forwarding offering materials to their customers.
 
18.   Miscellaneous.
 
The Offer is not being made to, nor will tenders be accepted from or on behalf of, holders of Shares in any jurisdiction in which the making of the Offer or acceptance thereof would not be in compliance with the laws of such jurisdiction. However, we may, in our discretion, take such action as we may deem necessary to make the Offer in any such jurisdiction and extend the Offer to holders of Shares in such jurisdiction.
 
No person has been authorized to give any information or make any representation on behalf of Purchaser or Biogen Idec not contained in this offer to purchase or in the related letter of transmittal and, if given or made, such information or representation must not be relied upon as having been authorized.

Ladies and Gentlemen:
 
The undersigned hereby tenders to FBC Acquisition Corp., a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of Biogen Idec Inc., a Delaware corporation (“Biogen Idec”), the above-described Shares of the Company, pursuant to Purchaser’s offer to purchase all of the outstanding Shares at $14.50 per Share, net to the seller in cash, without interest (and less any applicable withholding taxes), upon the terms and subject to the conditions set forth in the Offer to Purchase, receipt of which is hereby acknowledged, and in this Letter of Transmittal (which together, as each may be amended, supplemented or otherwise modified from time to time, constitute the ‘‘Offer”). We understand that Purchaser reserves the right to transfer or assign, in whole or from time to time in part, to one or more of its affiliates the right to purchase Shares tendered pursuant to the Offer, but any such transfer or assignment will not relieve Purchaser of its obligations under the Offer or prejudice the undersigned’s rights to receive payment for Shares validly tendered and accepted for payment.
 
Upon the terms and subject to the conditions of the Offer and effective upon acceptance for payment of and payment for the Shares, the undersigned hereby sells, assigns and transfers to, or upon the order of, Purchaser all right, title and interest in and to all of the Shares that are specified in, and being tendered by, this Letter of Transmittal (and any and all dividends, distributions, rights, other Shares or other securities issued or issuable in respect thereof on or after the date hereof (collectively, a “Distribution”)) and appoints the Depositary the true and lawful agent and attorney-in-fact of the undersigned with respect to such Shares (and any Distribution), with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to (i) transfer ownership of such Shares (and any Distribution), together with all accompanying evidences of transfer and authenticity, to or upon the order of Purchaser, (ii) take such further steps as may be necessary or advisable to facilitate a transfer of such Shares, (iii) present such Shares (and any Distribution) for transfer on the books of the Company and (iv) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares (and any Distribution), all in accordance with the terms of the Offer.
 
The undersigned hereby irrevocably appoints designees of Purchaser as the attorneys and proxies of the undersigned, each with full power of substitution, to exercise all voting and other rights of the undersigned in such manner as each such attorney and proxy or his substitute shall in his sole discretion deem proper, with respect to all of the Shares tendered hereby which have been accepted for payment by Purchaser prior to the time of any vote or other action (and any Distribution), at any meeting of stockholders of the Company (whether annual or special and whether or not an adjourned meeting), by written consent or otherwise. This proxy is irrevocable and is granted in consideration of, and is effective upon, the acceptance for payment of such Shares by Purchaser in accordance with the terms of the Offer. Such acceptance for payment shall revoke any other proxy or written consent granted by the undersigned at any time with respect to such Shares (and any Distribution), and no subsequent proxies will be given or written consents will be executed by the undersigned (and if given or executed, will not be deemed to be effective).
 
The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Shares tendered hereby (and any Distribution) and that when the same are accepted for payment by Purchaser, Purchaser will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claims. The undersigned will, upon request, execute and deliver any additional documents deemed by the Depositary or Purchaser to be necessary or desirable to complete the sale, assignment and transfer of the Shares tendered hereby (and any Distribution).
 
All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned, and any obligation of the undersigned hereunder shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned. Except as stated in the Offer, this tender is irrevocable.
 
The undersigned understands that tenders of Shares pursuant to the procedures described in “The Offer — Procedure for Tendering Shares” of the Offer to Purchase and in the instructions hereto will constitute an agreement between the undersigned and Purchaser upon the terms and subject to the conditions of the Offer.

Signatures on this Letter of Transmittal need not be guaranteed (i) if this Letter of Transmittal is signed by the registered holder(s) of the Shares (which term, for purposes of this document, shall mean any participant in the Book-Entry/Direct Registration System whose name appears on a security position listing as the owner of the Shares) tendered herewith or (ii) if such Shares are tendered for the account of an Eligible Institution. See Instruction 4.
 
2. Delivery of Letter of Transmittal and Shares.  This Letter of Transmittal is to be used with all tenders of Shares held in a DRS Account. A properly completed and duly executed Letter of Transmittal and any other documents required by this Letter of Transmittal must be received by the Depositary at one of its addresses set forth on the front page of this Letter of Transmittal by the Expiration Date (as defined in the Offer to Purchase). Stockholders who cannot deliver all required documents to the Depositary by the Expiration Date may tender their Shares pursuant to the guaranteed delivery procedure described in Section 4 of the Offer to Purchase. Pursuant to such procedure: (i) such tender must be made by or through an Eligible Institution; (ii) a properly completed and duly executed Notice of Guaranteed Delivery, substantially in the form provided by Purchaser, must be received by the Depositary prior to the Expiration Date; and (iii) a properly completed and duly executed Letter of Transmittal, and any other documents required by this Letter of Transmittal, must be received by the Depositary within three business days of the date of execution of such Notice of Guaranteed Delivery, as provided in “The Offer — Procedure for Tendering Shares” of the Offer to Purchase.
 
Stockholders utilizing the procedures for book-entry transfer as set forth in the Offer to Purchase will be deemed to have agreed to the terms set forth in this letter of transmittal upon delivery of an Agent’s Message as defined in the Offer to Purchase.
 
THE DELIVERY OF SHARES AND THE METHOD OF DELIVERY OF ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING STOCKHOLDER.
 
NO ALTERNATIVE, CONDITIONAL OR CONTINGENT TENDERS WILL BE ACCEPTED, AND NO FRACTIONAL SHARES WILL BE PURCHASED. BY EXECUTING THIS LETTER OF TRANSMITTAL, THE TENDERING STOCKHOLDER WAIVES ANY RIGHT TO RECEIVE ANY NOTICE OF THE ACCEPTANCE FOR PAYMENT OF THE SHARES.
 
3. Inadequate Space.  If the space provided herein is inadequate, the number of Shares tendered and any other relevant information should be listed on a separate signed schedule and attached hereto.
 
4. Signatures on Letter of Transmittal; Endorsements.  If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, the signature(s) must correspond with the name(s) as written on the security position listing.
 
If any of the Shares tendered hereby are held of record by two or more persons, all such persons must sign this Letter of Transmittal.
 
If a number of Shares registered in different names are tendered, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of Shares.
 
If this Letter of Transmittal is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or other person acting in a fiduciary or representative capacity, such person should so indicate when signing, and proper evidence satisfactory to Purchaser of the authority of such person so to act must be submitted.
 
5. Stock Transfer Taxes.  Except as otherwise provided in this instruction 5, Purchaser will pay any stock transfer taxes with respect to the sale and transfer of any Shares to it or its order pursuant to the Offer. If, however, a transfer tax is imposed for any reason other than the sale or transfer of Shares to Purchaser pursuant to the Offer, then the amount of any stock transfer taxes (whether imposed on the registered holder(s), such other person or otherwise) will be deducted from the purchase price unless satisfactory evidence of the payment of such taxes, or exemption therefrom, is submitted herewith.
 
6. Form W-9 and Backup Withholding.  Under U.S. federal income tax law, the Depositary may be required to withhold and pay over to the Internal Revenue Service (“IRS”) a portion of payments made to tendering stockholders or other payees pursuant to the Offer. In order to avoid such backup withholding, each tendering stockholder and other payee must provide the Depositary with its correct taxpayer identification number (“TIN”) and certify that it is not subject to such backup withholding


5


 

by completing the enclosed Form W-9 or establish another basis for exemption from backup withholding. In general, for an individual, the TIN is the Social Security Number of such individual. If the Depositary is not provided with the correct TIN, the stockholder or other payee may be subject to a penalty imposed by the IRS, and any reportable payments to such person may be subject to backup withholding at the applicable rate (currently 28%). Reportable payments will be subject to information reporting, even if the Depositary is provided with a TIN. For further information concerning backup withholding and instructions for completing the Form W-9 (including how to obtain a TIN if you do not have one and how to complete the Form W-9 if Shares are held in more than one name), please consult the instructions accompanying the enclosed Form W-9.
 
Certain persons (including, among others, corporations and certain foreign persons) are not subject to these backup withholding and reporting requirements. Exempt persons should indicate their exempt status on the Form W-9. A foreign person may qualify as an exempt recipient by submitting to the Depositary a properly completed IRS Form W-8BEN, Form W-8ECI or Form W-8IMY, as applicable (instead of Form W-9), signed under penalties of perjury, attesting to such stockholder’s exempt status. Stockholders are urged to consult their own tax advisors to determine whether they are exempt from these backup withholding and reporting requirements.
 
If backup withholding applies, the Depositary is required to withhold 28% of any payments made to a tendering stockholder or other payee. Backup withholding is not an additional U.S. federal income tax and any amounts withheld under the backup withholding rules may be refunded or credited against the stockholder’s U.S. federal income tax liability, if any, provided that the stockholder furnishes the required information to the IRS in a timely manner.
 
7. Waiver of Conditions.  The conditions of the Offer may be waived, in whole or in part, by Purchaser, to the extent legally permissible, in its sole discretion, at any time and from time to time, in the case of any Shares tendered.
 
8. Requests for Assistance or Additional Copies.  Questions or requests for assistance may be directed to the Information Agent at its address and telephone numbers set forth below. Additional copies of the Offer to Purchase, the Letter of Transmittal and the Notice of Guaranteed Delivery may be obtained from the Information Agent at its address and telephone numbers set forth below. Holders of Shares may also contact their broker, dealer, commercial bank or trust company or other nominee for assistance concerning the Offer.
 
IMPORTANT:  THIS LETTER OF TRANSMITTAL TOGETHER WITH ANY SIGNATURE GUARANTEES AND ANY OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION DATE OR THE TENDERING STOCKHOLDER MUST COMPLY WITH THE PROCEDURES FOR GUARANTEED DELIVERY.

Certification instructions.

General Instructions
Section references are to the Internal Revenue Code unless otherwise noted.
Purpose of Form
A person who is required to file an information return with the IRS must obtain your correct taxpayer identification number (TIN) to report, for example, income paid to you, real estate transactions, mortgage interest you paid, acquisition or abandonment of secured property, cancellation of debt, or contributions you made to an IRA.
     Use Form W-9 only if you are a U.S. person (including a resident alien), to provide your correct TIN to the person requesting it (the requester) and, when applicable, to:
     1. Certify that the TIN you are giving is correct (or you are waiting for a number to be issued),
     2. Certify that you are not subject to backup withholding, or
     3. Claim exemption from backup withholding if you are a U.S. exempt payee. If applicable, you are also certifying that as a U.S. person, your allocable share of any partnership income from a U.S. trade or business is not subject to the withholding tax on foreign partners’ share of effectively connected income.
Note. If a requester gives you a form other than Form W-9 to request your TIN, you must use the requester’s form if it is substantially similar to this Form W-9.
Definition of a U.S. person. For federal tax purposes, you are considered a U.S. person if you are:
   An individual who is a U.S. citizen or U.S. resident alien,
   A partnership, corporation, company, or association created or organized in the United States or under the laws of the United States,
   An estate (other than a foreign estate), or
   A domestic trust (as defined in Regulations section 301.7701-7).
Special rules for partnerships. Partnerships that conduct a trade or business in the United States are generally required to pay a withholding tax on any foreign partners’ share of income from such business. Further, in certain cases where a Form W-9 has not been received, a partnership is required to presume that a partner is a foreign person, and pay the withholding tax. Therefore, if you are a U.S. person that is a partner in a partnership conducting a trade or business in the United States, provide Form W-9 to the partnership to establish your U.S. status and avoid withholding on your share of partnership income.
     The person who gives Form W-9 to the partnership for purposes of establishing its U.S. status and avoiding withholding on its allocable share of net income from the partnership conducting a trade or business in the United States is in the following cases:
   The U.S. owner of a disregarded entity and not the entity,

 
 
    Cat. No. 10231X   Form W-9 (Rev. 10-2007)

 


 

Form W-9 (Rev. 10-2007)   Page 2

 
   The U.S. grantor or other owner of a grantor trust and not the trust, and
   The U.S. trust (other than a grantor trust) and not the beneficiaries of the trust.
Foreign person. If you are a foreign person, do not use Form W-9. Instead, use the appropriate Form W-8 (see Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities).
Nonresident alien who becomes a resident alien. Generally, only a nonresident alien individual may use the terms of a tax treaty to reduce or eliminate U.S. tax on certain types of income. However, most tax treaties contain a provision known as a “saving clause.” Exceptions specified in the saving clause may permit an exemption from tax to continue for certain types of income even after the payee has otherwise become a U.S. resident alien for tax purposes.
     If you are a U.S. resident alien who is relying on an exception contained in the saving clause of a tax treaty to claim an exemption from U.S. tax on certain types of income, you must attach a statement to Form W-9 that specifies the following five items:
     1. The treaty country. Generally, this must be the same treaty under which you claimed exemption from tax as a nonresident alien.
     2. The treaty article addressing the income.
     3. The article number (or location) in the tax treaty that contains the saving clause and its exceptions.
     4. The type and amount of income that qualifies for the exemption from tax.
     5. Sufficient facts to justify the exemption from tax under the terms of the treaty article.
     Example. Article 20 of the U.S.-China income tax treaty allows an exemption from tax for scholarship income received by a Chinese student temporarily present in the United States. Under U.S. law, this student will become a resident alien for tax purposes if his or her stay in the United States exceeds 5 calendar years. However, paragraph 2 of the first Protocol to the U.S.-China treaty (dated April 30, 1984) allows the provisions of Article 20 to continue to apply even after the Chinese student becomes a resident alien of the United States. A Chinese student who qualifies for this exception (under paragraph 2 of the first protocol) and is relying on this exception to claim an exemption from tax on his or her scholarship or fellowship income would attach to Form W-9 a statement that includes the information described above to support that exemption.
     If you are a nonresident alien or a foreign entity not subject to backup withholding, give the requester the appropriate completed Form W-8.
What is backup withholding? Persons making certain payments to you must under certain conditions withhold and pay to the IRS 28% of such payments. This is called “backup withholding.” Payments that may be subject to backup withholding include interest, tax-exempt interest, dividends, broker and barter exchange transactions, rents, royalties, nonemployee pay, and certain payments from fishing boat operators. Real estate transactions are not subject to backup withholding.
     You will not be subject to backup withholding on payments you receive if you give the requester your correct TIN, make the proper certifications, and report all your taxable interest and dividends on your tax return.
Payments you receive will be subject to backup
withholding if:
     1. You do not furnish your TIN to the requester,
     2. You do not certify your TIN when required (see the Part II instructions on page 3 for details),
     3. The IRS tells the requester that you furnished an incorrect TIN,
     4. The IRS tells you that you are subject to backup withholding because you did not report all your interest and dividends on your tax return (for reportable interest and dividends only), or
     5. You do not certify to the requester that you are not subject to backup withholding under 4 above (for reportable interest and dividend accounts opened after 1983 only).
     Certain payees and payments are exempt from backup withholding. See the instructions below and the separate Instructions for the Requester of Form W-9.
     Also see Special rules for partnerships on page 1.
Penalties
Failure to furnish TIN. If you fail to furnish your correct TIN to a requester, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.
Civil penalty for false information with respect to
withholding.
If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a $500 penalty.
Criminal penalty for falsifying information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.
Misuse of TINs. If the requester discloses or uses TINs in violation of federal law, the requester may be subject to civil and criminal penalties.
Specific Instructions

Form W-9 (Rev. 10-2007)   Page 3

 
Generally, individuals (including sole proprietors) are not exempt from backup withholding. Corporations are exempt from backup withholding for certain payments, such as interest and dividends.
Note. If you are exempt from backup withholding, you should still complete this form to avoid possible erroneous backup withholding.
     The following payees are exempt from backup withholding:
     1. An organization exempt from tax under section 501(a), any IRA, or a custodial account under section 403(b)(7) if the account satisfies the requirements of section 401(f)(2),
     2. The United States or any of its agencies or instrumentalities,
     3. A state, the District of Columbia, a possession of the United States, or any of their political subdivisions or instrumentalities,
     4. A foreign government or any of its political subdivisions, agencies, or instrumentalities, or

2However, the following payments made to a corporation (including gross proceeds paid to an attorney under section 6045(f), even if the attorney is a corporation) and reportable on Form 1099-MISC are not exempt from backup withholding: medical and health care payments, attorneys’ fees, and payments for services paid by a federal executive agency.
Part I. Taxpayer Identification
Number (TIN)
Enter your TIN in the appropriate box. If you are a resident alien and you do not have and are not eligible to get an SSN, your TIN is your IRS individual taxpayer identification number (ITIN). Enter it in the social security number box. If you do not have an ITIN, see How to get a TIN below.
     If you are a sole proprietor and you have an EIN, you may enter either your SSN or EIN. However, the IRS prefers that you use your SSN.
     If you are a single-member LLC that is disregarded as an entity separate from its owner (see Limited liability company (LLC) on page 2), enter the owner’s SSN (or EIN, if the owner has one). Do not enter the disregarded entity’s EIN. If the LLC is classified as a corporation or partnership, enter the entity’s EIN.
Note. See the chart on page 4 for further clarification of name and TIN combinations.
How to get a TIN. If you do not have a TIN, apply for one immediately. To apply for an SSN, get Form SS-5, Application for a Social Security Card, from your local Social Security Administration office or get this form online at www.ssa.gov. You may also get this form by calling 1-800-772-1213. Use Form W-7, Application for IRS Individual Taxpayer Identification Number, to apply for an ITIN, or Form SS-4, Application for Employer Identification Number, to apply for an EIN. You can apply for an EIN online by accessing the IRS website at www.irs.gov/businesses and clicking on Employer Identification Number (EIN) under Starting a Business. You can get Forms W-7 and SS-4 from the IRS by visiting www.irs.gov or by calling 1-800-TAX-FORM (1-800-829-3676).
     If you are asked to complete Form W-9 but do not have a TIN, write “Applied For” in the space for the TIN, sign and date the form, and give it to the requester. For interest and dividend payments, and certain payments made with respect to readily tradable instruments, generally you will have 60 days to get a TIN and give it to the requester before you are subject to backup withholding on payments. The 60-day rule does not apply to other types of payments. You will be subject to backup withholding on all such payments until you provide your TIN to the requester.
Note. Entering “Applied For” means that you have already applied for a TIN or that you intend to apply for one soon.
Caution: A disregarded domestic entity that has a foreign owner must use the appropriate Form W-8.
Part II. Certification
To establish to the withholding agent that you are a U.S. person, or resident alien, sign Form W-9. You may be requested to sign by the withholding agent even if items 1, 4, and 5 below indicate otherwise.
     For a joint account, only the person whose TIN is shown in Part I should sign (when required). Exempt payees, see Exempt Payee on page 2.
Signature requirements. Complete the certification as indicated in 1 through 5 below.
     1. Interest, dividend, and barter exchange accounts opened before 1984 and broker accounts considered active during 1983. You must give your correct TIN, but you do not have to sign the certification.
     2. Interest, dividend, broker, and barter exchange accounts opened after 1983 and broker accounts considered inactive during 1983. You must sign the certification or backup withholding will apply. If you are subject to backup withholding and you are merely providing your correct TIN to the requester, you must cross out item 2 in the certification before signing the form.


 


 

Form W-9 (Rev. 10-2007)   Page 4

 
     3. Real estate transactions. You must sign the certification. You may cross out item 2 of the certification.
     4. Other payments.

Secure Your Tax Records from Identity Theft
Identity theft occurs when someone uses your personal information such as your name, social security number (SSN), or other identifying information, without your permission, to commit fraud or other crimes. An identity thief may use your SSN to get a job or may file a tax return using your SSN to receive a refund.
     To reduce your risk:
  Protect your SSN,
  Ensure your employer is protecting your SSN, and
  Be careful when choosing a tax preparer.
     Call the IRS at 1-800-829-1040 if you think your identity has been used inappropriately for tax purposes.
     Victims of identity theft who are experiencing economic harm or a system problem, or are seeking help in resolving tax problems that have not been resolved through normal channels, may be eligible for Taxpayer Advocate Service (TAS) assistance. You can reach TAS by calling the TAS toll-free case intake line at 1-877-777-4778 or TTY/TDD 1-800-829-4059.
Protect yourself from suspicious emails or phishing schemes. Phishing is the creation and use of email and websites designed to mimic legitimate business emails and websites. The most common act is sending an email to a user falsely claiming to be an established legitimate enterprise in an attempt to scam the user into surrendering private information that will be used for identity theft.
     The IRS does not initiate contacts with taxpayers via emails. Also, the IRS does not request personal detailed information through email or ask taxpayers for the PIN numbers, passwords, or similar secret access information for their credit card, bank, or other financial accounts.

Notice of Offer to Purchase for Cash
All Outstanding Shares of Common Stock (including the Associated
Preferred Stock Purchase Rights)
of
Facet Biotech Corporation
at
$14.50 Net Per Share
by
FBC Acquisition Corp.
a wholly owned subsidiary of
Biogen Idec Inc.
FBC Acquisition Corp. (“Purchaser”), a Delaware corporation and a wholly owned subsidiary of Biogen Idec Inc., a Delaware corporation (“Biogen Idec”), is offering to purchase all of the outstanding shares of common stock, par value $0.01 per share, of Facet Biotech Corporation, a Delaware corporation (the “Company”), including the associated preferred stock purchase rights issued or to be issued under the Rights Agreement, dated as of September 7, 2009, between the Company and Mellon Investor Services LLC, as Rights Agent (the “Rights” and, together with the common stock, the “Shares”), at a price of $14.50 per Share, net to the seller in cash, without interest (and less any applicable withholding taxes), upon the terms and subject to the conditions set forth in the Offer to Purchase dated September 21, 2009 (the “Offer to Purchase”), and in the related Letter of Transmittal (which together, as amended, supplemented or otherwise modified from time to time, constitute the “Offer”).
THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY TIME, ON OCTOBER 19, 2009, UNLESS THE OFFER IS EXTENDED.
The Offer is conditioned upon, among other things, (1) there being validly tendered and not properly withdrawn prior to the expiration of the Offer a total number of Shares representing, together with the Shares owned by Biogen Idec, at least a majority of the total voting power of all of the outstanding shares of the Company entitled to vote generally in the election of directors or with respect to a merger, calculated on a fully diluted basis, (2) Biogen Idec being satisfied that the restrictions on business combinations with interested stockholders set forth in Section 203 of the Delaware General Corporation Law are inapplicable to the Offer and the Proposed Merger (as defined below) or any other business combination involving Biogen Idec or any of its subsidiaries (including Purchaser) and the Company, (3) all waiting periods under applicable antitrust laws, including the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, having expired or been terminated, (4) the Company’s board of directors redeeming the Rights, or Biogen Idec being satisfied that the Rights have been invalidated or are otherwise inapplicable to the Offer and the Proposed Merger and (5) the Company not having entered into or effectuated any agreement or transaction with any person or entity having the effect of impairing Purchaser’s or Biogen Idec’s ability to acquire the Company or otherwise diminishing the expected value to Biogen Idec of the acquisition of the Company other than, except as to terms not disclosed in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on August 31, 2009, the collaboration and license agreement and related stock purchase agreement between the Company and Trubion Pharmaceuticals, Inc. disclosed in such current report. The Offer is also subject to the satisfaction of certain other conditions set forth in Section 15 of the Offer to Purchase.
The purpose of the Offer and the Proposed Merger is for Biogen Idec to acquire control of, and the entire equity interest in, the Company. The Offer is the first step in the acquisition of the Company. Biogen Idec currently intends, as soon as practicable following the consummation of the Offer, to seek to have Purchaser consummate a merger with the Company (the “Proposed Merger”). Pursuant to the Proposed Merger, each then outstanding share of common stock (other than those held by Biogen Idec, held in the treasury of the

 


 

Company, held by subsidiaries of the Company, if any, and held by Company stockholders who have not tendered their Shares in the Offer and who properly exercise appraisal rights) would be converted, pursuant to the terms of the Proposed Merger, into the right to receive an amount in cash per share of common stock equal to the highest price per Share paid by Purchaser pursuant to the Offer, without interest (and less any applicable withholding taxes). Upon consummation of the Proposed Merger, the Company would be a wholly owned subsidiary of Biogen Idec.
Biogen Idec is seeking to negotiate with the Company with respect to the acquisition of the Company by Biogen Idec. Biogen Idec and Purchaser reserve the right to (i) amend the Offer (including amending the number of Shares to be purchased and/or amending the purchase price) upon entering into a merger agreement with the Company or (ii) negotiate a merger agreement with the Company that does not involve a tender offer, pursuant to which merger agreement Purchaser would terminate the Offer and the Shares would, upon consummation of the merger contemplated by such merger agreement, be converted into cash or other consideration negotiated by Biogen Idec, Purchaser and the Company.
For purposes of the Offer, Purchaser shall be deemed to have accepted for payment tendered Shares when, as and if Purchaser gives notice of its acceptance to Computershare Trust Company, N.A., the Depositary for the Offer (the “Depositary”). Purchaser will pay for Shares accepted for payment pursuant to the Offer by depositing the purchase price with the Depositary. The Depositary will act as agent for all tendering stockholders for the purpose of receiving payments from Purchaser and transmitting such payments to tendering stockholders whose Shares have been accepted for payment. Under no circumstances will interest be paid on the consideration paid for Shares pursuant to the Offer, regardless of any delay in making such payment. If Purchaser increases the consideration to be paid for Shares in the Offer, Purchaser will pay such increased consideration for all Shares purchased pursuant to the Offer. In all cases, payment for Shares accepted for payment pursuant to the Offer will be made only after (i) timely receipt by the Depositary of confirmation of a book-entry transfer of such Shares into the Depositary’s account at the book-entry transfer facility and an Agent’s Message (as defined in the Offer to Purchase) or (ii) if Shares are held in a direct registration system account (a “DRS Account”) with the Company’s transfer agent, timely receipt by the Depositary of a properly completed and duly executed Letter of Transmittal and any other documents required by the Letter of Transmittal. Accordingly, payment may be made to tendering stockholders at different times if delivery of the Shares and other required documents occurs at different times.
“Expiration Date” means 12:00 midnight, New York City time, on October 19, 2009, unless Purchaser extends the period of time for which the Offer is open, in which event, the Expiration Date means the latest time and date on which the Offer, as so extended, shall expire. Purchaser reserves the right, subject to applicable laws and regulations, in its sole discretion, at any time and from time to time, (i) to extend the period of time during which the Offer is open, and thereby delay the acceptance of, and the payment for, the Shares and (ii) to amend the Offer in any other respect, by giving notice of such extension or amendment to the Depositary. Any extension or amendment of the Offer will be followed as promptly as practicable by a public announcement, in the case of an extension, to be made no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.
Purchaser does not currently intend to include a subsequent offering period with the Offer, although it reserves the right to do so in its sole discretion. Under Rule 14d-7 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), no withdrawal rights apply to Shares tendered during a subsequent offering period and no withdrawal rights apply during the subsequent offering period with respect to Shares tendered in the Offer and accepted for payment. Purchaser will offer the same form and amount of consideration for Shares in a subsequent offering period, if it includes one, as in the Offer.
Tendering stockholders may withdraw tenders of Shares made pursuant to the Offer at any time prior to the Expiration Date. Thereafter, such tenders are irrevocable, except that if Purchaser has not accepted tendered Shares for payment by the date that is 60 days from the date of the original Offer, they may be withdrawn at any time after such date until such Shares have been accepted for payment as provided in the Offer to Purchase.
To withdraw tendered Shares, a written notice of withdrawal with respect to the Shares must be timely received by the Depositary at one of its addresses set forth on the back cover of the Offer to Purchase, and the notice of withdrawal must specify the name of the person(s) who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the registered holder of Shares, if different from that of the person(s) who tendered such Shares. If the Shares to be withdrawn have been delivered to the Depositary, a signed notice of withdrawal with (except in the case of Shares tendered by a financial institution that is a member of a recognized Medallion Program approved by The Securities Transfer Association, Inc. (each, an “Eligible Institution”)) signatures guaranteed by an Eligible Institution must be submitted prior to the release of such Shares. In addition, such notice must specify (i) in the case of Shares tendered by book-entry transfer, the name and number of the account at the book-entry transfer facility to be credited with the withdrawn Shares or (ii) in the case of Shares held in a DRS Account, the name and number of the DRS Account. Withdrawals may not be rescinded, and Shares withdrawn will thereafter be deemed not validly tendered for purposes of the Offer. However, withdrawn Shares may be re-tendered by again following one of the procedures described in the Offer to Purchase at any time prior to the Expiration Date. Purchaser will determine, in its sole discretion, all questions as to the form and validity (including time of receipt) of any notice of withdrawal, and its determination shall be final and binding.
The receipt of cash pursuant to the Offer or the Proposed Merger by holders of Shares will be a taxable transaction for U.S. federal income tax purposes. Holders of Shares should consult their own tax advisor regarding the particular tax consequences of the Offer and the Proposed Merger to them, including the tax consequences under state, local, foreign and other tax laws.
The information required to be disclosed by Rule 14d-6(d)(1) of the General Rules and Regulations under the Exchange Act is contained in the Offer to Purchase and is incorporated herein by reference.
A request is being made to the Company pursuant to Rule 14d-5 of the General Rules and Regulations under the Exchange Act for use of the Company’s stockholder lists and security position listings for the purpose of disseminating the Offer to stockholders. The Offer to Purchase, the Letter of Transmittal and all other relevant materials will be mailed to record holders of Shares and will be furnished to brokers, dealers, banks, trust companies and similar persons whose names, or the names of whose nominees, appear on the Company’s stockholders lists, or, if applicable, who are listed as participants in a clearing agency’s security position listing, for subsequent transmittal to beneficial owners of Shares.
The Offer to Purchase and the related Letter of Transmittal contain important information which should be read carefully before any decision is made with respect to the Offer.

BIOGEN IDEC COMMENCES TENDER OFFER FOR FACET BIOTECH
— Offers to Acquire All Outstanding Shares of Facet for $14.50 Per Share in Cash —
Cambridge, MA, September 21, 2009 — Biogen Idec Inc. (NASDAQ:BIIB) announced today that FBC Acquisition Corp., its wholly owned subsidiary, has commenced a tender offer to acquire all of the outstanding shares of Facet Biotech Corporation (NASDAQ:FACT) for $14.50 per share in cash, in furtherance of its previously announced acquisition proposal. The tender offer is scheduled to expire at 12:00 midnight, ET, on October 19, 2009, unless extended or terminated.
The tender offer follows a written proposal made by Biogen Idec to Facet Biotech’s Board of Directors on September 4, 2009 to acquire all of the outstanding shares of Facet Biotech in a negotiated transaction. Biogen Idec’s all-cash offer represented a premium of approximately 64% over the $8.82 per share closing price of Facet Biotech’s common stock on September 3, 2009, the last trading day before Biogen Idec publicly announced its acquisition proposal. In light of the rejection of the proposal by Facet Biotech’s Board of Directors on September 8, 2009 and its refusal to discuss a business combination of the two companies on the terms proposed, Biogen Idec has decided to present its offer directly to Facet Biotech’s stockholders.
“We believe this proposed transaction makes compelling business sense for both Facet Biotech and Biogen Idec and is in the best interests of our respective stockholders,” said Biogen Idec’s President and Chief Executive Officer James C. Mullen. “Our $14.50 per share, all-cash offer ascribes meaningful and appropriate value to Facet Biotech and represents an extremely attractive opportunity for Facet Biotech’s shareholders to realize today the future value of their company. In addition, we believe the transaction would enable the important multiple sclerosis and solid tumor clinical programs that the companies have been working on in collaboration for nearly four years to have the best chance of reaching the market and improving patients’ lives.”
In commencing the tender offer, Biogen Idec today also sent a letter to the Board of Directors of Facet Biotech addressing several statements in Facet Biotech’s letter and press release of September 8, 2009 in which it rejected Biogen Idec’s $14.50 per share, all-cash offer. Among other things, Biogen Idec’s letter explains that, on the basis of Facet Biotech’s own disclosures, Facet Biotech’s available cash is considerably below the Biogen Idec offer price when the following factors are included in the analysis: Facet Biotech’s cash burn rate of $8 million per month for the remainder of 2009; the $30 million in cash spent as part of the Trubion collaboration, as well as future development costs and milestone payments under the terms of

 


 

that agreement; Facet Biotech’s total lease obligations of approximately $208 million on an undiscounted basis, as well as additional obligations of nearly $19 million; and, inclusion of shares underlying Facet Biotech’s outstanding options. Biogen Idec’s letter also points out, contrary to Facet Biotech’s assertions, that because Facet Biotech’s net cash per share is considerably below Biogen Idec’s offer price, the offer ascribes meaningful value to daclizumab, which Biogen Idec is jointly developing for the treatment of relapsing multiple sclerosis, additional programs in its pipeline, its technology platform, related milestone payments, and synergies. The letter sent today to Facet Biotech’s Board of Directors follows below:
September 21, 2009
Facet Biotech Corporation
Board of Directors
c/o Faheem Hasnain, President and Chief Executive Officer
1500 Seaport Boulevard
Redwood City, CA 94063
Dear Faheem:
Biogen Idec is today commencing a tender offer to acquire all of the outstanding shares of Facet Biotech Corporation for $14.50 per share in cash. As you know, we have repeatedly expressed our interest in discussing with Facet Biotech’s Board of Directors and management team the potential acquisition of Facet Biotech by Biogen Idec in a negotiated transaction, but have been told that Facet Biotech has no interest in discussing a potential transaction on the terms we proposed. In light of the rejection of the proposal by Facet Biotech’s Board of Directors on September 8, 2009, we are presenting our $14.50 per share, all-cash offer directly to Facet Biotech’s stockholders.
In commencing this tender offer, we would like to address for the record certain of the assertions you made through the September 8, 2009 letter and press release rejecting our offer, as well as in subsequent communications to the investment community.
First, Facet Biotech has stated inaccurately that Biogen Idec’s $14.50 per share proposal “represents only the cash on [Facet Biotech’s] balance sheet and fails to attribute any value to daclizumab, or to the rest of [Facet Biotech’s] R&D pipeline and platform.” Specifically, Facet Biotech asserts that its cash balance as of June 30, 2009 represents a per share cash value of approximately $15.11. In fact, Facet Biotech’s available cash is considerably below our offer price of $14.50 per share when the following factors are accounted for:
    In public statements, Facet Biotech has estimated that it will use approximately $80 million in cash in 2009 and indicated that about $32 million had already been spent through June 30, 2009. This implies that the monthly cash usage is about $8 million for the rest of 2009. Each month that passes is another month in which Facet Biotech’s cash balance decreases.

 


 

    Facet Biotech also recently spent $30 million in cash as part of its Trubion collaboration, in addition to committing to funding future development costs and milestone payments, which it has since confirmed are not included in its estimated $80 million per year cash expenditure rate. This new collaboration obligation represents a significant cash burden to Facet Biotech.
    Facet Biotech also has significant lease and other obligations. As you recently disclosed, Facet Biotech has total lease obligations on an undiscounted basis of approximately $208 million. Facet Biotech’s most recent Quarterly Report discloses additional obligations totaling over $12 million related to manufacturing, post retirement benefits, and other obligations.
    Facet Biotech has referred to its cash per share using shares outstanding as of July 31, 2009, but this overstates the amount because it does not reflect the shares underlying outstanding options.
When these factors are included in the per share cash analysis, the available cash is significantly below the reported June 30, 2009 balance.
Second, Facet Biotech claims that Biogen Idec’s proposal does not reflect the value of daclizumab, additional programs in its pipeline, its technology platform, related milestone payments, and synergies. However, the fact that Facet Biotech’s net cash per share is considerably below our offer price means that Biogen Idec’s proposal does ascribe meaningful value for these operating assets. Further, Biogen Idec’s $14.50 offer represents a 64% premium over the $8.82 per share closing price of Facet Biotech on September 3, 2009.
Third, Facet Biotech suggests that “the significance of the [interim futility analysis regarding daclizumab] has not been fully appreciated by the investment community.” In fact, Facet Biotech’s stock price increased approximately 13% on the day following the announcement regarding the interim futility analysis and 27% from that day to the day prior to the announcement of the Trubion collaboration, evidencing a significant appreciation for the futility analysis findings in the market.
Fourth, Facet Biotech suggests that it only entered into the Trubion collaboration “after concluding that it was a positive for [Facet’s] stockholders and was likely to be a positive synergistic opportunity for Biogen Idec as well.” We believe that our view that the Trubion collaboration is value destructive has been corroborated by the fact that Facet Biotech’s stock price dropped 22% in the five trading days following the announcement of the Trubion collaboration and prior to Biogen Idec’s proposal.
Finally, Facet Biotech has disclosed that it expects its cash balance to be completely depleted by the end of 2012, despite the fact that the company will have significant remaining obligations and the need to continue funding its clinical programs, including importantly, the clinical programs in which it is partnered with Biogen Idec.

 


 

Biogen Idec’s proposal represents an extremely attractive opportunity for Facet Biotech’s shareholders to receive today the future value of the company. We continue to urge you to engage in discussions with us so that we may reach a definitive merger agreement.
Sincerely,
/s/ James C. Mullen
President and Chief Executive Officer
Biogen Idec’s tender offer is not subject to any financing condition or approval by Biogen Idec stockholders.
