 - 7 - 








 
executed joinder substantially in the form attached hereto as Exhibit C (the “Joinder”) whereby such transferee agrees in writing to be bound by the terms of this
Agreement, in which case such transferee shall be deemed to be a Supporting Noteholder for all purposes herein from and after the date on which such joinder is executed. Notwithstanding the foregoing, any transferee that specifies in the

L.P. nor any fund managed by such entity shall be permitted to become a Supporting Noteholder under this Agreement. Any Transfer of any Prepetition Noteholder Claim that does not comply with this Section 7(b) shall be deemed void ab
initio.

non-public controlled affiliate of the foregoing to purchase or take assignment of any additional Prepetition Noteholder Claims; provided, however, that, in the event a Supporting Noteholder or any non-public controlled affiliate of
the foregoing purchases or takes assignment of any such additional Prepetition Noteholder Claims after the date hereof, such additional Prepetition Noteholder Claims shall immediately upon such acquisition become subject to the terms of this
Agreement without any further action being required (or, in the case of a purchase by a non-public controlled affiliate of a Supporting Noteholder (other than an affiliate acting solely in its capacity as a Qualified Marketmaker) such Supporting
Noteholder, as applicable, shall cause its non-public controlled affiliate to become subject to the terms of this Agreement in connection with such purchased claims). For purposes of this Section 7(c), a “non-public controlled
affiliate” of a Supporting Noteholder shall not include any such entity that is subject to an investment restriction that, as determined in good faith by its investment manager, limits its ability to hold illiquid equity securities that would
be inconsistent with consummation of a Stand-Alone Plan (as defined in the Plan Term Sheet).

Party hereto shall have any continuing liability or obligation to any other Party hereunder and the provisions of this Agreement shall have no further force or effect, except for the provisions in Sections 12, 13 and 15 through
23, each of which shall survive termination of this Agreement; provided that no such termination shall relieve any Supporting Noteholder from liability for its breach or non-performance of its obligations hereunder prior to the date of
such termination and the rights of any Party as it relates to such breach or non-performance by any Supporting Noteholder shall be preserved in the event of the occurrence of such breach or non-performance.

 11. Fiduciary Duties. Notwithstanding anything to the contrary herein, nothing in this
Agreement shall require the Debtors or any directors or officers of the Debtors (in such person’s capacity as a director or officer of the Debtors) to take any action, or to refrain from taking any action, to the extent such action or
forbearance is inconsistent with its or their fiduciary obligations under applicable law, as determined after consultation with outside legal counsel. 

12. No Third-Party Beneficiaries. This Agreement shall be solely for the benefit of the Parties hereto, and no other Person shall be a
third-party beneficiary hereof. 
 13. Entire Agreement. As of the date this Agreement becomes effective, this Agreement (and any
confidentiality agreements entered into in connection herewith or described in Section 6(a) hereof) constitutes the entire agreement among the Parties hereto with respect to the subject matter hereof and supersedes all other prior
agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. 
 14. Amendment or
Waiver. 
 (a) This Agreement may not be modified, altered, amended, waived, or supplemented except by an agreement in writing signed by
each of the Debtors and the Requisite Supporting Noteholders. Notwithstanding the foregoing, this Section 14(a) may not be modified, altered, or amended except in writing signed by each of the Debtors and the Supporting Noteholders. 

(b) Each of the Parties agrees to negotiate in good faith all amendments and modifications to this Agreement as reasonably necessary and
appropriate to consummate the Restructuring. Such agreement shall not be deemed to prejudice or limit in any way any Party’s rights under Section 10 of this Agreement. 

(c) No waiver of any of the provisions of this Agreement shall be deemed or constitute a waiver of any other provision of this Agreement,
whether or not similar, nor shall any waiver be deemed a continuing waiver. 
 15. Governing Law. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York, including all matters of construction, validity, and performance without giving effect to the conflicts of laws provisions thereof except New York General Obligations Law
Section 5-1401. Each Party hereby irrevocably submits to the jurisdiction of any state court or federal court located in New York County, New York in respect of any suit, action, or proceeding arising out of or relating to this Agreement, and
irrevocably accepts for itself and in respect of its property, generally and unconditionally, jurisdiction of the aforesaid courts. Each Party irrevocably waives, to the fullest extent it may effectively do so under applicable law, any objection
that it may now or hereafter have to the laying of venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action, or proceeding brought in any such court has been brought in an inconvenient forum.
Nothing herein shall affect the right of any Party to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against any other party in any other jurisdiction. Notwithstanding the foregoing consent
to New York jurisdiction, if the Bankruptcy Cases are commenced, each Party agrees that the Bankruptcy Court shall have exclusive jurisdiction of all matters arising out of or in connection with this Agreement. 

  
 - 14 - 








 16. Counterparts. This Agreement may be executed in any number of counterparts and by
different Parties in separate counterparts and by facsimile or other electronic means, with the same effect as if all Parties had signed the same document. All such counterparts shall be deemed an original, shall be construed together, and shall
constitute one and the same instrument. 
 17. Assignment; Severability. Without limiting the obligations of each Supporting
Noteholder pursuant to Section 7(b) hereof, this Agreement is intended to bind and inure to the benefit of the Parties and their respective successors, assigns, heirs, executors, administrators and representatives. Any term or provision
of this Agreement that is invalid or unenforceable in any jurisdiction, shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions
of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to
be only as broad as is enforceable. 
 18. Specific Performance. It is understood and agreed by the Parties that money damages would
not be a sufficient remedy for any breach of this Agreement by any Party and each non-breaching Party shall be entitled to specific performance and injunctive or other equitable relief as a remedy of any such breach, without the necessity of proving
the inadequacy of monetary damages as a remedy, including an order of the Bankruptcy Court requiring any Party to comply promptly with any of its obligations hereunder. 

19. Representation by Counsel. Each Party acknowledges that it has had the opportunity to be represented by counsel in connection with
this Agreement and the transactions contemplated by this Agreement. Accordingly, any rule of law or any legal decision that would provide any Party with a defense to the enforcement of the terms of this Agreement against such Party based upon lack
of legal counsel, shall have no application and is expressly waived. 
 20. Settlement Discussions. This Agreement is part of a
proposed settlement of matters that could otherwise be the subject of litigation among the Parties hereto. Nothing herein shall be deemed an admission of any kind. Pursuant to Federal Rule of Evidence 408, any applicable state rules of evidence and
any other applicable law, foreign or domestic, this Agreement and all negotiations relating thereto shall not be admissible into evidence in any proceeding other than to prove the existence of this Agreement or in a proceeding to enforce the terms
of this Agreement. 
 21. Confidentiality. Unless legally obligated by law, regulation, subpoena, civil investigative demand, the
rules of any regulatory authority or stock exchange or other compulsory process (including in connection with any governmental or third party approval of the Restructuring or in connection with any litigation concerning the Restructuring), each of
the Parties agrees and acknowledges that, prior to the Petition Date, it will not disclose to any Person the content or any term or provision of this Agreement, other than (a) to the representatives of each such Party who are subject to an
equivalent duty of confidentiality (or, in the case of a 

  
 - 15 - 








 
Supporting Noteholder, to another Supporting Noteholder), in each case, in connection with the transactions contemplated hereby or (b) in the case of a Supporting Noteholder, as permitted by
any existing confidentiality agreement between such Supporting Noteholder and the Company, the provisions of which shall control in all cases with respect to the obligations under this Section 21 prior to the Petition Date.
Notwithstanding the foregoing, a Supporting Noteholder may disclose the content or any term or provision of this Agreement, without any notice to the other Parties, to a regulatory or self-regulatory authority with jurisdiction over its operations
generally in the course of such authority’s routine examination or request. From and after the commencement of the Bankruptcy Cases on the Petition Date, the Parties acknowledge and agree that this Agreement and its contents shall be publicly
disclosed by the Debtors, whether in filings by the Debtors with the Bankruptcy Court regarding this Agreement or by the Debtors under applicable law or stock exchange rule. 

22. Fees. The Debtors shall reimburse or pay in cash, on a monthly basis, all reasonable documented costs and expenses of the
Supporting Noteholders, including, without limitation, the fees, costs and expenses of (i) Brown Rudnick LLP and Fox Rothschild LLP incurred prior to termination of this Agreement in accordance with Section 10 hereof, and
(ii) Jefferies LLC, which fees, costs and expenses shall be payable pursuant to the terms set forth in the relevant engagement letter with the Company and, for the avoidance of doubt, to the extent that Jeffries is entitled to a fee tail in
accordance with such engagement letter, such fee tail will have the same priority as if the Jeffries’ engagement letter has been assumed by the Debtors. The Debtors’ reimbursement of the legal fees of the Supporting Noteholders shall be
limited to the reasonable fees, costs and expenses of one counsel and one local counsel; provided, however that the Supporting Noteholders reserve the right to retain additional counsel and/or a consultant in the event that a
Stand-Alone Plan (as defined in the Term Sheet) is implemented, which retention, if any, shall be negotiated in good faith with the Debtors. The Debtors shall pay such reasonable documented costs and expenses of the Supporting Noteholders within
fifteen (15) calendar days after receipt by the Debtors of a reasonably detailed invoice, which invoice may be redacted to protect privileged and/or material non-public information. In the event that there is an objection to the payment of
certain professional fees and/or expenses of the Supporting Noteholders, the Debtors shall remain obligated to pay those amounts not subject to an objection within such time period. Unless otherwise ordered by the Bankruptcy Court, no recipient of
such payment shall be required to file with respect thereto any interim or final fee application with the Bankruptcy Court. 
 23.
Consideration. The Parties acknowledge that, other than the agreements, covenants, representations, and warranties set forth herein and to be included in the Plan Documents, no consideration shall be due or paid to any Supporting Noteholder
in exchange for its obligations under this Agreement.

investment agreement (as the case may be) at the Auction (as defined below) (or, in the event that an Auction is not conducted because only one Qualified Bid is received by the Bid Deadline, upon entry into such asset purchase agreement or
investment agreement (as the case may be) in accordance with the Bidding Procedures, the Debtors shall prosecute confirmation of the applicable plan scenario (i.e., 363 Sale or Plan Sale).

attorneys and other advisors to each of the foregoing.
	 	 
	Conditions to Effectiveness	  	The Plan shall contain such conditions to effectiveness of the applicable Plan alternatives customary in plans of reorganization or plans of
liquidation, as the case may be, of such type.
	 	 
	Milestones	  	Milestones related to the Plan and the Competitive Process shall be as set forth in Section 10 of the Plan Support Agreement and the
Bidding Procedures, respectively.

Noteholders, including as to status as a private company, board selection, rights under a shareholders agreement and trading restrictions.
	 	 
	Minority Holder Protections	  	If warranted under the circumstances, the constituent documents of the Reorganized Company shall contain appropriate minority investor
protections, which shall be negotiated in good faith by and among the Debtors, the Supporting Noteholders and the Creditors’ Committee.
	 	 
	Private Company Status	  	It is the intention of the parties that the Reorganized Company be a private, non-SEC reporting company.
	 	 
	Management Incentive Plan	  	In a Stand-Alone Plan, any Management Incentive Plan will be acceptable in all respects to the Supporting Noteholders, and the

 EXHIBIT 2 

BIDDING PROCEDURES 
 (to be
attached) 







 BIDDING PROCEDURES1 

By the Motion, Dendreon Corporation and its direct and indirect subsidiaries that are debtors and debtors in possession in the jointly
administered chapter 11 cases pending in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”) under Case No. 14-12515 (together the “Debtors”),2 sought approval of, among other things, the procedures through which they will, with the consultation of the Committee and the other Consultation Parties (each term as defined herein) determine the
highest or otherwise best offer for the sale of substantially all of their non-cash assets (the “Acquired Assets”). 
 On
December 17, 2014 the Bankruptcy Court entered an order (the “Bidding Procedures Order”), which, among other things, authorized the Debtors to determine the highest or otherwise best offer for the Acquired Assets through the
process and procedures set forth below (the “Bidding Procedures”). The Bidding Procedures provide that the Debtors may also consider bids in the form of a recapitalization transaction effectuated through a chapter 11 plan of
reorganization, subject to the requirements set forth herein (a “Chapter 11 Plan Bid”). In addition, the Debtors may designate a stalking horse bidder (the “Stalking Horse Bidder”) in accordance with the procedures
set forth below. 
 To the extent the Bidding Procedures require the Debtors to consult with the Committee or other Consultation Parties in
connection with making a determination or taking an action, the Debtors shall do so in a regular and timely manner prior to making such determination or taking such action. 

Acquired Assets to Be Sold 

The Debtors are offering for sale all of the Acquired Assets. Except in the case of a Chapter 11 Plan Bid and except as otherwise provided in
the Acquisition Agreement or a Modified Acquisition Agreement (both as defined below) submitted by a Successful Bidder (as defined below) (including any exhibits or schedules thereto) all of the Debtors’ right, title and interest in and to the
Acquired Assets subject thereto shall be sold free and clear of any pledges, liens, security interests, encumbrances, claims, charges, options and interests thereon (collectively, the “Interests”) to the maximum extent permitted by
section 363 of the Bankruptcy Code, with such Interests to attach to the net proceeds of the sale of the Acquired Assets with the same validity and priority as such Interests applied against the Acquired Assets. More detail regarding the Acquired
Assets will be posted in the electronic data room. 
  

	1 	Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to them in the motion for approval of, among other things, the Bidding Procedures (the “Motion”).



	2 	The Debtors and the last four digits of their respective taxpayer identification numbers are as follows: Dendreon Corporation (3193), Dendreon Holdings, LLC (8047), Dendreon Distribution, LLC (8598) and Dendreon
Manufacturing, LLC (7123). The address of the Debtors’ corporate headquarters is 1301 2nd Avenue, Seattle, Washington 98101. 








 Bidding Process 

The Debtors and their advisors shall, subject to the other provisions of these Bidding Procedures, including the consultation obligations set
forth herein and the Bidding Procedures Order, (i) determine whether any person is a Qualified Bidder (as defined below), (ii) coordinate the efforts of Qualified Bidders in conducting their due diligence investigations, (iii) receive
offers from Qualified Bidders, (iv) negotiate any offers made to purchase the Acquired Assets, and (v) determine if any Qualified Bidder should be selected as a Stalking Horse Bidder. 

Key Dates For Potential Competing Bidders 

The Bidding Procedures provide interested parties with the opportunity to qualify for and participate in an auction to be conducted by the
Debtors (the “Auction”) and to submit competing bids for the Acquired Assets. The Debtors shall assist Qualified Bidders in conducting their respective due diligence investigations and shall accept Bids (as defined below) until
January 27, 2015 at 5:00 p.m. (prevailing Eastern Time) (the “Bid Deadline”). 
 The key dates for the sale
process are as follows: 
  

			
	December 29, 2014	 	Stalking Horse Deadline
	 	 
	January 27, 2015 at 5:00 P.M. EST	 	Bid Deadline - Due Date for Bids and Deposits
	 	 
	February 3, 2015 at 10:00 A.M. EST	 	Auction
	 	 
	January 27, 2015 at 10:00 A.M. EST	 	Objection Deadline in Connection with Sale of Acquired Assets to a Successful
Bidder3
	 	 
	February 5, 2015 at 9:30 A.M. EST	 	Sale Hearing

 The Debtors will be deemed to have accepted a 363 Bid only when the 363 Bid has been approved by the
Bankruptcy Court at the Sale Hearing. In the event that the Successful Bid is a Chapter 11 Plan Bid, the Sale Hearing will not occur and the Debtors will prosecute confirmation of a plan of reorganization consistent with such Chapter 11 Plan Bid.

 In the event of a material change in circumstances regarding the sale process, the Debtors shall consult with the Consultation Parties
regarding whether to extend any of the deadlines set forth in these Bidding Procedures or otherwise change the procedures in any material respect. 

 

	3 	This objection deadline applies to all objections to the Sale Motion and the Sale of the Acquired Assets to a Successful Bidder, with the exception of objections related to adequate assurance performance by the
Successful Bidder or any changes to the Acquisition Agreement.

 Procedures for the Designation of a Stalking Horse Bidder 

The Debtors, in consultation with the Consultation Parties, may select a Stalking Horse Bidder for the Acquired Assets for the purposes of
establishing a minimum acceptable bid with which to begin the Auction (the “Stalking Horse Bid”) and provide such Stalking Horse Bidder with the Bid Protections; provided that no insider or affiliate of the Debtors shall be
entitled to any Bid Protections; and provided further that (a) the Debtors have provided five business days’ notice to the Committee, the Supporting Noteholders, the United States Trustee and those parties who have filed the
appropriate notice pursuant to Bankruptcy Rule 2002 requesting notice of all pleadings filed in the Chapter 11 Cases (the “Stalking Horse Notice Parties”), with no further notice being required, of such Stalking Horse Bid and
provision of Bid Protections (the “Stalking Horse Objection Period”), and (b) the Court has entered an order approving the Bid Protections following expiration of the Stalking Horse Objection Period (x) upon certification
of counsel if no objection from any of the Stalking Notice Parties has been received within the Stalking Horse Objection Period or (y) after an emergency hearing if an objection from any of the Stalking Horse Notice Parties has been received
within the Stalking Horse Objection Period. The Debtors shall have until December 29, 2014 (the “Stalking Horse Deadline”) to select a Qualified Bid of a Qualified Bidder to be a Stalking Horse Bid. The Debtors shall
finalize a purchase agreement with a Stalking Horse Bidder (the “Stalking Horse Agreement”) by no later than the Stalking Horse Deadline. Within one (1) day following the Stalking Horse Deadline the Debtors shall file with
the Bankruptcy Court a notice (the “Stalking Horse Notice”) of such Stalking Horse Bid and a copy of the Stalking Horse Agreement. The Debtors shall serve such Stalking Horse Notice on (i) all entities known to have
expressed an interest in a transaction with respect to the Acquired Assets during the past twelve (12) months, (ii) all entities known to have asserted any lien, claim, interest or encumbrance in or upon any of the Acquired Assets,
(iii) counsel to each of the Supporting Noteholders, (iv) counsel to the Committee, and (v) counsel to any other official committee appointed in the Chapter 11 Cases. 

Due Diligence 
 Access to
Diligence Materials. 
 To participate in the bidding process and to receive access to due diligence (the
“Diligence Materials”), a party must submit to the Debtors (i) an executed confidentiality agreement substantially in the form attached hereto as Exhibit A or such other form reasonably satisfactory to the Debtors,
in consultation with the Consultation Parties and (ii) reasonable evidence demonstrating the party’s financial capability to consummate a sale transaction for the Acquired Assets or a recapitalization transaction pursuant to a chapter 11
plan of reorganization (any such transaction, a “Transaction”) as reasonably determined by the Debtors, in consultation with the Consultation Parties. A party who qualifies for access to Diligence Materials pursuant to the prior
sentence shall be a “Qualified Bidder.” 
 The Debtors will afford any Qualified Bidder the time and opportunity to conduct
reasonable due diligence, as determined by the Debtors, in consultation with the Consultation Parties, including reasonable access to management, access to the electronic data room and other information that a Qualified Bidder may reasonably
request; provided, however, that the Debtors shall not be obligated to furnish any due diligence information after the Bid Deadline to any 

  
 3 








 
party that has not submitted a Qualified Bid (as defined below). The Debtors reserve the right to withhold any Diligence Materials that the Debtors determine, in consultation with the
Consultation Parties, are business-sensitive or otherwise not appropriate for disclosure to a Qualified Bidder who is a competitor of the Debtors or is affiliated with any competitor of the Debtors. Neither the Debtors nor their representatives
shall be obligated to furnish information of any kind whatsoever to any person that is not determined to be a Qualified Bidder. 
 All due
diligence requests must be directed to Lazard Frères & Co. LLC, 30 Rockefeller Plaza, New York, NY 10020, to the attention of Sven Pfeiffer (sven.pfeiffer@lazard.com; Phone: 212-632-6583; Fax: 212-332-8365). 

Due Diligence from Qualified Bidders. 

Each Qualified Bidder shall comply with all reasonable requests for additional information and due diligence access by the Debtors or their
advisors regarding the ability of such Qualified Bidder, as applicable, to consummate its contemplated transaction. Failure by a Qualified Bidder to comply with requests for additional information and due diligence access may be a basis for the
Debtors, in consultation with the Consultation Parties, to determine that such bidder is no longer a Qualified Bidder. Failure by a Qualified Bidder to comply with requests for additional information and due diligence access may be a basis for the
Debtors, in consultation with the Consultation Parties, to determine that a bid made by such Qualified Bidder is not a Qualified Bid. 

Auction Qualification Process 

To be eligible to participate in the Auction, each offer, solicitation or proposal (each, a “Bid”), must be reasonably
determined by the Debtors, in consultation with the Consultation Parties, to satisfy each of the following conditions: 
  

	 	(a)	Good Faith Deposit: Each Bid must be accompanied by a deposit in the amount of ten percent (10%) of the purchase price contained in the Modified Acquisition Agreement (defined below), before any reductions
for assumed liabilities, or, in the case of a Chapter 11 Plan Bid, ten percent (10%) of the amount of the capital investment contemplated by such bid, before any reductions for assumed liabilities, to an interest-bearing escrow account to be
identified and established by the Debtors (the “Good Faith Deposit”). 

  

	 	(b)	Same or Better Terms: Each Bid must be on terms that the Debtors, in their business judgment and after consulting with the Consultation Parties, determine are the same or better than the terms of either
(i) the Acquisition Agreement, or (ii) in the event the Debtors enter into a Stalking Horse Agreement, the Stalking Horse Agreement. 

  

	 	(c)	 Executed Agreement: Each Bid must be based on the proposed acquisition agreement, which will be prepared by the Debtors in consultation with
the Consultation Parties, and will be filed with the Bankruptcy Court no later than the day after the Stalking Horse Deadline (the “Acquisition Agreement”) and must include executed transaction documents, signed by an authorized
representative of 



  
 4 









	 	
such Qualified Bidder, pursuant to which the Qualified Bidder proposes to effectuate a Transaction (a “Modified Acquisition Agreement”).4 Each Bid must also include a copy of the Acquisition Agreement marked against the Modified Acquisition Agreement to show all changes requested by the Qualified Bidder (including the inclusion of the
purchase price). Each Modified Acquisition Agreement must provide (1) a commitment to close within two business days after all closing conditions are met and (2) a representation that the Qualified Bidder will (a) make all necessary
filings under the Hart Scott Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and (b) submit all necessary filings under the HSR Act within ten (10) days following the effective date of the Modified
Acquisition Agreement. 

 In the event the Debtors enter into a Stalking Horse Agreement each Bid must include a copy of the
Modified Acquisition Agreement marked against the Stalking Horse Agreement. 
  

	 	(d)	Minimum Bid: A Bid (including a Chapter 11 Plan Bid) for all or substantially all of the Debtors’ non-cash assets must propose a minimum purchase price, including any assumption of liabilities and any
earnout or similar provisions, that in the Debtors’ reasonable business judgment, after consulting with the Consultation Parties, has a value greater than $275,000,0005. 


In the event that the Debtors, in consultation with the Consultation Parties, enter into a Stalking Horse Agreement, a Bid for all or
substantially all of the Debtors’ assets (or in the case of a Chapter 11 Plan Bid for the equity of reorganized Dendreon) must propose a minimum purchase price, including any assumption of liabilities and any earnout or similar provisions, that
in the Debtors’ reasonable business judgment, after consulting with the Consultation Parties, has a value greater than (i) the purchase price set forth in any Stalking Horse Purchase Agreement, (ii) the Break-Up Fee (as defined in the
Sale Motion), if any (iii) the Expense Reimbursement Amount (as defined in the Sale Motion), if any, (iv) the Assumed Liabilities (as defined in the Stalking Horse Agreement), as applicable, and (v) the Overbid Amount6, as applicable the sum of which shall be the “Stalking Horse Auction Minimum Bid Amount”. 

 

	4 	If the Bid is a Chapter 11 Plan Bid and the Debtors have not filed a form of investment agreement with the Bankruptcy Court within at least ten (10) business days prior to the Bid Deadline, any Qualified Bidder
submitting a Chapter 11 Plan Bid shall submit a Modified Acquisition Agreement marked as appropriate. If a form of investment agreement has been filed, any Qualified Bidder submitting a Chapter 11 Plan Bid shall submit a modified investment
agreement (a “Modified Investment Agreement”). All requirements of these Bid Procedures that apply to a Modified Acquisition Agreement shall apply to a Modified Investment Agreement. 


	5 	To the extent a Supporting Noteholder submits a Bid, such Bid must be a cash Bid. 


	6 	The “Overbid Amount” shall be $1 million. 


  
 5 









	 	(e)	Designation of Assigned Contracts and Leases: A Bid must identify any and all executory contracts and unexpired leases of the Debtors that the Qualified Bidder wishes to be assumed and, with respect to any Bid
that is not a Chapter 11 Plan Bid, assigned to the Qualified Bidder at closing, pursuant to a Transaction. A Bid must specify whether the Debtors or the Qualified Bidder will be responsible for any cure costs associated with such assumption, and
include a good faith estimate of such cure costs (which estimate may be provided by the Debtors). 

  

	 	(f)	Designation of Assumed Liabilities: A Bid must identify all liabilities which the Qualified Bidder proposes to assume. 

  

	 	(g)	Corporate Authority: A Bid must include written evidence reasonably acceptable to the Debtors, after consulting with the Consultation Parties, demonstrating appropriate corporate authorization to consummate the
proposed Transaction; provided that, if the Qualified Bidder is an entity specially formed for the purpose of effectuating the Transaction, then the Qualified Bidder must furnish written evidence reasonably acceptable to the Debtors, after
consulting with the Consultation Parties, of the approval of the Transaction by the equity holder(s) of such Qualified Bidder. 

  

	 	(h)	Disclosure of Identity of Qualified Bidder: A Bid must fully disclose the identity of each entity that will be bidding for or purchasing the Acquired Assets or otherwise participating in connection with such Bid,
and the complete terms of any such participation, including any agreements, arrangements or understandings concerning a collaborative or joint bid or any other combination concerning the proposed Bid. 


 

	 	(i)	Proof of Financial Ability to Perform: A Bid must include written evidence that the Debtors may reasonably conclude, in consultation with their advisors and the Consultation Parties, demonstrates that the
Qualified Bidder has the necessary financial ability to close the Transaction and provide adequate assurance of future performance under all contracts to be assumed and assigned in such Transaction. Such information must include,
inter alia, the following: 

  

	 	(1)	contact names and numbers for verification of financing sources; 

  

	 	(2)	 written evidence of the Qualified Bidder’s internal resources and proof of any debt funding commitments from a recognized banking institution
and, if applicable, equity commitments in an aggregate amount equal to the cash portion of such Bid or the posting of an irrevocable letter of credit 



  
 6 









	 	
from a recognized banking institution issued in favor of the Debtors in the amount of the cash portion of such Bid, in each case, as are needed to close the Transaction; 


 

	 	(3)	the Qualified Bidder’s current financial statements (audited if they exist) or other similar financial information reasonably acceptable to the Debtors; 


 

	 	(4)	a description of the Qualified Bidder’s pro forma capital structure (and, in the case of a Chapter 11 Plan Bid, the Debtors’ pro forma capital structure); and 


 

	 	(5)	any such other form of financial disclosure or credit-quality support information or enhancement reasonably acceptable to the Debtors, in consultation with the Consultation Parties, demonstrating that such Qualified
Bidder has the ability to close the Transaction. 

  

	 	(j)	Regulatory and Third Party Approvals: A Bid must set forth each regulatory and third-party approval required for the Qualified Bidder to consummate the Transaction, and the time period within which the Qualified
Bidder expects to receive such regulatory and third-party approvals, and the Debtors, in consultation with the Consultation Parties, may consider the timing of such approvals, and any actions the Qualified Bidder will take to ensure receipt of such
approval(s) as promptly as possible, when considering the other Bid Assessment Criteria (defined below). 

  

	 	(k)	Contact Information and Affiliates: A Bid must provide the identity and contact information for the Qualified Bidder and full disclosure of any parent companies of the Qualified Bidder. 


 

	 	(l)	Contingencies: A Bid may not be conditioned on obtaining financing or any internal approval, or on the outcome or review of due diligence. 


 

	 	(m)	Irrevocable: A Bid must be irrevocable until the Good Faith Deposit associated with such Bid must be returned in accordance with the terms hereof (or, if the Successful Bid is a Chapter 11 Plan Bid, until
confirmation of such plan of reorganization), provided that if such Bid is accepted as the Successful Bid or the Backup Bid (as defined below), such Bid shall continue to remain irrevocable, subject to the terms and conditions of the Bidding
Procedures. 

  

	 	(n)	Compliance with Diligence Requests. The Qualified Bidder submitting a Bid must have complied with reasonable requests for additional information and due diligence access from the Debtors (as described above) to
the reasonable satisfaction of the Debtors, in consultation with the Consultation Parties. 

  

	 	(o)	Confidentiality Agreement. To the extent not already executed, a Bid must include an executed confidentiality agreement substantially in the form attached hereto as Exhibit A or otherwise in form and
substance reasonably satisfactory to the Debtors, after consulting with the Consultation Parties. 


  
 7 









	 	(p)	Termination Fees. Except with respect to any Stalking Horse Bidder, a Bid must not entitle the Qualified Bidder to any break-up fee, termination fee or similar type of payment or reimbursement and, by submitting
a Bid, the Qualified Bidder waives the right to pursue a substantial contribution claim under 11 U.S.C. § 503 related in any way to the submission of its Bid or participation in any Auction (as defined below). 


A Bid received from a Qualified Bidder that meets the above requirements for the applicable assets, as determined by the Debtors in their sole
discretion after consulting with the Consultation Parties, shall constitute a “Qualified Bid” for such assets; provided that if the Debtors receive a Bid prior to the Bid Deadline that is not a Qualified Bid the Debtors may,
in consultation with the Consultation Parties, provide the Qualified Bidder with the opportunity to remedy any deficiencies prior to the Auction; provided, further, that, for the avoidance of doubt, if any Qualified Bidder fails to
comply with reasonable requests for additional information and due diligence access from the Debtors to the satisfaction of the Debtors, in consultation with the Consultation Parties, the Debtors may, after consulting with the Consultation Parties,
disqualify any Qualified Bidder and Qualified Bid in the Debtor’s discretion, and such Qualified Bidder shall not be entitled to attend or participate in the Auction. 

Bid Deadline 
 The
following parties must receive a Bid in writing, on or before January 27, 2015 at 5:00 p.m. (prevailing Eastern Time) or such earlier date as may be agreed to by each of the Debtors, after consulting with the Consultation Parties (the
“Bid Deadline”): (1) the Debtors, 200 Crossing Boulevard, Bridgewater, NJ 08807, Attn: Robert Crotty (rcrotty@dendreon.com); (2) counsel for the Debtors, Skadden, Arps, Slate, Meagher & Flom LLP, Four Times
Square, New York, NY 10036, Attn: Ken Ziman (ken.ziman@skadden.com), 155 N. Wacker Drive, Chicago, IL, 60606, Attn: Felicia Perlman (felicia.perlman@skadden.com), and 500 Boylston Street, Boston, MA 02116, Attn: Graham Robinson
(graham.robinson@skadden.com); (3) financial advisor to the Debtors, Lazard Frères & Co. LLC, 30 Rockefeller Plaza, New York, NY 10020, Attn: Sven Pfeiffer (sven.pfeiffer@lazard.com) and Brandon Aebersold
(brandon.aebersold@lazard.com); and (4) proposed counsel to the Committee, Sullivan & Cromwell LLP, 125 Broad Street, New York, NY 10004-2498, Attention: Michael H. Torkin (torkinm@sullcrom.com) and Krishna Veeraraghavan
(Veeraraghavank@sullcrom.com) and Young Conaway Stargatt & Taylor, LLP, Rodney Square, 1000 N. King Street, Wilmington, Delaware 19801, Attention: Pauline K. Morgan (pmorgan@ycst.com). The Debtors shall provide a copy of each
Bid received to counsel to any Supporting Noteholder that (i) does not submit a Qualified Bid, and (ii) has confirmed in writing that it will not be providing financing to, or otherwise directly or indirectly participating in a bid
submitted by, any Qualified Bidder who has submitted a Qualified Bid. 
 Auction 

If two or more Qualified Bids are received by the Bid Deadline, or in the event the Debtors, after consulting with the Consultation Parties,
enter into a Stalking Horse Agreement and one Qualified Bid other than that submitted by the Stalking Horse Bidder is received by the 

  
 8 








 
Bid Deadline, the Debtors will conduct an auction (the “Auction”) to determine the highest or otherwise best Qualified Bid. This determination shall take into account any factors
the Debtors, in consultation with the Consultation Parties, reasonably deem relevant to the value of the Qualified Bid to the estates and may include, but are not limited to, the following: (a) the amount and nature of the consideration,
including any assumed liabilities; (b) the number, type and nature of any changes to the Acquisition Agreement requested by each Qualified Bidder; (c) the extent to which such modifications or provisions are likely to delay closing of the
sale of the Debtors’ assets and the cost to the Debtors of such modifications or delay; (d) the total consideration to be received by the Debtors; (e) the likelihood of the Qualified Bidder’s ability to close a transaction and
the timing thereof; (f) the net benefit to the Debtors’ estates, taking into account, if applicable, any Stalking Horse Bidder’s right to any Break Up Fee or Expense Reimbursement Amount, and (f) any other qualitative or
quantitative factor the Debtors, in consultation with the Consultation Parties, deem reasonably appropriate under the circumstances (collectively, the “Bid Assessment Criteria”). 

If two or more Qualified Bids are not received by the Bid Deadline, or in the event the Debtors, after consulting with the Consultation
Parties, enter into a Stalking Horse Agreement, if one Qualified Bid other than that submitted by the Stalking Horse Bidder is not received by the Bid Deadline, the Debtors may, after consulting with the Consultation Parties, determine not to
conduct the Auction. If the Debtors have not entered into a Stalking Horse Agreement and only one Qualified Bid is received by the Bid Deadline, the Debtors may, after consulting with the Consultation Parties, select the Modified Acquisition
Agreement of such Qualified Bidder to be the Successful Bid and such Qualified Bidder shall be the Successful Bidder. In the event the Debtors, after consulting with the Consultation Parties, enter into a Stalking Horse Agreement, if a Qualified Bid
other than that submitted by the Stalking Horse Bidder is not received by the Bid Deadline, the Stalking Horse Agreement shall become the Successful Bid and the Stalking Horse Qualified Bidder shall be the Successful Bidder. In the event that the
Debtors have not entered into a Stalking Horse Agreement and no Qualified Bids are received by the Bid Deadline, the Debtors shall pursue a restructuring with the Supporting Noteholders, as outlined in the Plan Support Agreement and the Plan Term
Sheet attached thereto. 
 Procedures for Auction 

The Auction, if necessary, shall take place on or before February 3, 2015 at 10:00 a.m. (prevailing Eastern Time) at the offices of
counsel for the Debtors, Skadden, Arps, Slate, Meagher & Flom LLP, Four Times Square, New York, NY 10036, or such other place and time as the Debtors shall notify all Qualified Bidders that have submitted Qualified Bids (including the
Stalking Horse Bidder, if any), the Supporting Noteholders and their counsel, the Committee and its counsel, and any other official committee appointed in the Debtors’ chapter 11 cases and its counsel. The Auction shall be conducted according
to the following procedures: 
 Participation. 

Any creditor shall be permitted to attend the Auction. Only such Qualified Bidders (including the Stalking Horse Bidder, if any), or such other

 The Debtors Shall Conduct the Auction. 

The Debtors and their professionals shall direct and preside over the Auction and the Auction shall be transcribed. Other than as expressly set
forth herein, the Debtors, in consultation with the Consultation Parties, may conduct the Auction in the manner they reasonably determine will result in the highest or otherwise best Qualified Bid. The Debtors shall use their best efforts to provide
each participant in the Auction with a copy of the Modified Acquisition Agreement associated with the highest or otherwise best Qualified Bid received before the Bid Deadline (such highest or otherwise best Qualified Bid the “Auction
Baseline Bid”). In addition, at the start of the Auction, the Debtors shall describe the terms of the Auction Baseline Bid. Each Qualified Bidder (including the Stalking Horse Bidder, if any) participating in the Auction must confirm that
it (a) has not engaged in any collusion with respect to the bidding or sale of any of the assets described herein, (b) has reviewed, understands and accepts the Bidding Procedures and (c) has consented to the core jurisdiction of the
Bankruptcy Court (as described more fully below). 
 Terms of Overbids. 

An “Overbid” is any bid made at the Auction subsequent to the Debtors’ announcement of the respective
Auction Baseline Bid. Any Overbid for purposes of this Auction must comply with the following conditions: 
  

	 	(a)	Minimum Overbid Increments: Any Overbid after and above the respective Auction Baseline Bid shall be made in increments valued at not less than $250,000. In order to maximize value, the Debtors reserve the right,
in consultation with the Consultation Parties, to announce reductions or increases in the minimum incremental bids (or in valuing such bids) at any time during the Auction. Additional consideration in excess of the amount set forth in the respective
Auction Baseline Bid may include cash and/or noncash consideration, provided, however, that the value for such non-cash consideration shall be determined by the Debtors, in consultation with the Consultation Parties, in their
reasonable business judgment. 

  

	 	(b)	 Remaining Terms Are the Same as for Qualified Bids: Except as modified herein or by the Debtors at the Auction, in consultation with the
Consultation Parties, an Overbid at the Auction must comply with the conditions for a Qualified Bid set forth above, provided, however, that (i) the Bid Deadline shall not apply, (ii) no additional Good Faith Deposit shall be
required beyond the Good Faith Deposit previously submitted by a Qualified Bidder, provided that the Successful Bidder shall be required to make a representation at the end of the Auction that it will




  
 10 









	 	
provide any additional deposit necessary so that its Good Faith Deposit is equal to the amount of ten percent (10%) of the purchase price, or ten percent 10% of the capital investment,
contained in the Successful Bid, and (iii) each Overbid may be based on the Auction Baseline Bid, or any other form Modified Acquisition Agreement submitted prior to the Auction. Any Overbid must include, in addition to the amount and the form
of consideration of the Overbid, a description of all changes (if any) requested by the Qualified Bidder to the Acquisition Agreement or a previously submitted Modified Acquisition Agreement, in connection therewith (including any changes to the
designated assigned contracts and leases and assumed liabilities). Any Overbid must remain open and binding on the Qualified Bidder. 


At the Debtors’ discretion, to the extent not previously provided (which shall be determined by the Debtors in consultation with the
Consultation Parties), a Qualified Bidder submitting an Overbid at the Auction must submit, as part of its Overbid, written evidence (in the form of financial disclosure or credit-quality support information or enhancement reasonably acceptable to
the Debtors, in consultation with the Consultation Parties) reasonably demonstrating such Qualified Bidder’s ability to close the Transaction proposed by such Overbid. 

Announcement and Consideration of Overbids. 
  

	 	(a)	Announcement of Overbids: The Debtors shall announce at the Auction the material terms of each Overbid, the total amount of consideration offered in each such Overbid, and the basis for calculating such total
consideration and such other terms as the Debtors, in consultation with the Consultation Parties, reasonably determine will facilitate the Auction. 

  

	 	(b)	Consideration of Overbids: Subject to the deadlines set forth herein, the Debtors reserve the right, in consultation with the Consultation Parties, in their reasonable business judgment, to make one or more
continuances of the Auction to, among other things: facilitate discussions between the Debtors and individual Qualified Bidders; allow individual Qualified Bidders to consider how they wish to proceed; or give Qualified Bidders the opportunity to
provide the Debtors with such additional evidence as the Debtors in their reasonable business judgment (after consulting with the Consultation Parties) may require, that the Qualified Bidder has sufficient internal resources, or has received
sufficient non-contingent debt and/or equity funding commitments, to consummate the proposed Transaction at the prevailing Overbid amount. 


Backup Bidder. 
 Notwithstanding
anything in the Bidding Procedures to the contrary, if an Auction is conducted, the Qualified Bidder with the next highest or otherwise best Bid at the Auction, as determined by the Debtors, in the exercise of their business judgment and after
consulting with the Consultation Parties, will be designated as the backup bidder (the “Backup Bidder”). The Backup Bidder shall be required to keep its initial Bid (or if the Backup Bidder submitted one or


  
 11 








 
more Overbids at the Auction, the Backup Bidder’s final Overbid) (the “Backup Bid”) open and irrevocable until the earlier of (i) 5:00 p.m. (prevailing Eastern Time) on
the date that is sixty (60) days after the date of entry of the Sale Order, or, if the Successful Bid is a Chapter 11 Plan Bid, until the effective date of such plan of reorganization (the “Outside Backup Date”), or
(ii) the closing of the transaction with the Successful Bidder. 
 Following the Sale Hearing, if the Successful Bidder fails to
consummate an approved transaction, the Backup Bidder will be deemed to have the new prevailing bid, and the Debtors will be authorized, but not required, without further order of the Bankruptcy Court, to consummate the transaction with the Backup
Bidder. In such case of a breach or failure to perform on the part of the Successful Bidder (including any Backup Bidder designated as a Successful Bidder), the defaulting Successful Bidder’s deposit shall be forfeited to the Debtors. The
Debtors, on their behalf and on behalf of each of their respective estates, specifically reserve the right to seek all available damages, including specific performance, from any defaulting Successful Bidder (including any Backup Bidder designated
as a Successful Bidder) in accordance with the terms of the Bidding Procedures. 
 Additional Procedures. 

The Debtors, after consulting with the Consultation Parties, may announce at the Auction additional procedural rules that are reasonable under
the circumstances for conducting the Auction, so long as such rules are not inconsistent in any material respect with the Bidding Procedures. 

Consent to Jurisdiction and Authority as Condition to Bidding. 

All Qualified Bidders (including the Stalking Horse Bidder, if any) shall be deemed to have (1) consented to the core jurisdiction of the
Bankruptcy Court to enter an order or orders, which shall be binding in all respects, in any way related to the Bidding Procedures, the Auction, or the construction and enforcement of any Modified Acquisition Agreement or any other document relating
to any Transaction, (2) waived any right to a jury trial in connection with any disputes relating to the Bidding Procedures, the Auction, or the construction and enforcement of any Modified Acquisition Agreement or any other document relating
to any Transaction and (3) consented to the entry of a final order or judgment in any way related to the Bidding Procedures, the Auction, or the construction and enforcement of any Modified Acquisition Agreement or any other document relating
to any Transaction if it is determined that the Bankruptcy Court would lack Article III jurisdiction to enter such a final order or judgment absent the consent of the parties. 

Sale Is As Is/Where Is. 
 Except as
otherwise provided in the Modified Acquisition Agreement or the Sale Order, the Acquired Assets or any other assets of the Debtors sold pursuant to the Bidding Procedures, shall be conveyed at the closing of a transaction with a Successful Bidder in
their then-present condition, “AS IS, WITH ALL FAULTS, AND WITHOUT ANY WARRANTY WHATSOEVER, EXPRESS OR IMPLIED.” 

  
 12 








 Closing the Auction. 

The Auction shall continue until there is one Qualified Bid for the Acquired Assets or a Chapter 11 Plan Bid that the Debtors determine in
their reasonable business judgment, after consulting with the Consultation Parties, is the highest or otherwise best Qualified Bid at the Auction. Thereafter, the Debtors shall select such Qualified Bid, in consultation with the Consultation
Parties, as the overall highest or otherwise best Qualified Bid (such Bid, the “Successful Bid,” and the Qualified Bidder submitting such Successful Bid, the “Successful Bidder”). In making this decision, the
Debtors shall consider, in consultation with the Consultation Parties, the Bid Assessment Criteria. 
 The Auction shall close when the
Successful Bidder submits fully executed sale and transaction documents memorializing the terms of the Successful Bid. 
 Promptly following
the Debtors’ selection, after consulting with the Consultation Parties, of the Successful Bid and the conclusion of the Auction, the Debtors shall announce the Successful Bid and Successful Bidder and shall file with the Bankruptcy Court notice
of the Successful Bid and Successful Bidder. 
 Unless otherwise required pursuant to the Debtors’ fiduciary duties, the Debtors shall
not consider any Bids submitted after the conclusion of the Auction. 
 Return of Good Faith Deposits 

The Good Faith Deposits of all Qualified Bidders shall be held in one or more interest-bearing escrow accounts by the Debtors, but shall not
become property of the Debtors’ estates absent further order of the Bankruptcy Court. The Good Faith Deposit of any Qualified Bidder that is neither the Successful Bidder nor the Backup Bidder shall be returned to such Qualified Bidder not
later than five (5) business days after the Sale Hearing. The Good Faith Deposit of the Backup Bidder, if any, shall be returned to the Backup Bidder on the date that is the earlier of 72 hours after (a) the closing of the transaction with
the Successful Bidder and (b) the Outside Backup Date. Upon the return of the Good Faith Deposits, their respective owners shall receive any and all interest that will have accrued thereon. If the Successful Bidder timely closes the winning
transaction, its Good Faith Deposit shall be credited towards the purchase price. 
 The Consultation Parties 

The Debtors shall consult with the Supporting Noteholders, the Official Committee of Unsecured Creditors appointed by the Bankruptcy Court on
November 19, 2014 (the “Committee”), and any other official committee appointed in the Debtors’ chapter 11 cases, and each of their respective advisors (collectively, the “Consultation Parties” and each, a
“Consultation Party”) as explicitly provided for in the Bidding Procedures; provided, however, that the Debtors shall not be required to consult with any Consultation Party (and its advisors) that is a Qualified Bidder
unless such Qualified Bidder does not submit a bid by the Bid Deadline, at which time, such Supporting Noteholder shall become a Consultation Party; provided, further that if any individual Supporting Noteholder becomes a Qualified
Bidder, the consultation rights of any Supporting Noteholder that has not become a Qualified Bidder shall not be affected. 

  
 13 








 Reservation of Rights of the Debtors 

Except as otherwise provided in the Acquisition Agreement, the Bidding Procedures or the Bidding Procedures Order, the Debtors further reserve
the right as they may reasonably determine to be in the best interest of their estates, in consultation with the Consultation Parties to: (a) determine which bidders are Qualified Bidders; (b) determine which Bids are Qualified Bids;
(c) determine whether to enter into a Stalking Horse Agreement; (d) determine which Qualified Bid is the highest or otherwise best proposal and which is the next highest or otherwise best proposal; (e) reject any Bid that is
(1) inadequate or insufficient, (2) not in conformity with the requirements of the Bidding Procedures or the requirements of the Bankruptcy Code or (3) contrary to the best interests of the Debtors and their estates; (f) waive
terms and conditions set forth herein with respect to all potential bidders; (g) impose additional terms and conditions with respect to all potential bidders; (h) extend the deadlines set forth herein; (i) continue or cancel the
Auction and/or Sale Hearing in open court without further notice; and (j) modify the Bidding Procedures and implement additional procedural rules that the Debtors determine, in their business judgment, after consulting with the Consultation
Parties, will better promote the goals of the bidding process and discharge the Debtors’ fiduciary duties and are not inconsistent with any Bankruptcy Court order.
