Notes, each Existing Bondholder hereby converts the Notes. Attached hereto as Schedule II are executed conversion notices completed in accordance with the requirements of the Relevant Indentures. The Company and each Existing Bondholder agrees that
the number of shares of the Company’s common stock, no par value (the “Common Stock”) that each Existing Bondholder will receive in connection with such conversion is set forth on Schedule I hereto opposite such Existing
Bondholder’s name under the column “Conversion Shares”. The conversion thereof shall have the effects specified in the Relevant Indenture governing the applicable Notes, including, (i) the receipt by the Existing
Bondholders of Conversion Shares that do not bear a Restricted Securities Legend (as such term is defined in the Relevant Indenture), and (ii) in exchange for the Conversion Shares, a release by the Existing Bondholders of all claims arising
out of or related to the Notes, including, but not limited to, all accrued and unpaid interest. 
  
 1.2 Private Placement Additional Shares. In consideration of and for such conversion, the Company agrees to issue both
Existing Bondholder an additional number of shares of Common Stock set forth opposite such Existing Bondholder’s name under the column “Restricted Shares” on Schedule I hereto (such shares being referred to herein as the
“Restricted Shares”). Each Existing Bondholder acknowledges that the Restricted Shares may not be transferred, sold or otherwise disposed of (collectively a “Transfer”) unless registered under the Securities Act of

Bondholder acknowledges and agrees that the Restricted Shares will bear customary legends and restrictions on transfer to such effect. 
  
 1.3 Registration Rights. Concurrently with the
execution and delivery hereof, the Company and the Existing Bondholders have entered into a Registration Rights Agreement in substantially the form of Exhibit B hereto.

under any federal securities laws, rules or regulations that may govern what constitutes a beneficial owner for purposes of determining reporting obligations and/or a person’s or entity’s constituting an affiliate of the Company) of more
than 9.5% of the outstanding shares of Common Stock of the Company on a fully-diluted basis immediately following the issuance of such Restricted Shares (such number of shares of Common Stock otherwise due to the Existing Bondholder’s above and
beyond such 9.5% level as so determined being the “Exercise Shares”). In such event, the Company shall issue warrants (the “Warrants”) to such Existing Bondholder(s) exercisable for an exercise price of zero (0.00)
substantially in the form of Exhibit A hereto. 
  
 1.5 Shares. The Conversion Shares and the Restricted Shares are sometimes collectively referred to herein as the “Shares.”

November __, 2005 or at such other time on the same date or such other date as the Existing Bondholders and the Company shall agree in writing (such time and date, the “Closing Date”). No party hereto shall have an obligation to
close the transaction contemplated hereunder, and this Agreement shall be rescinded without any liability or obligation on the part of any party, if the note offering contemplated by the October 27, 2005 offering circular previously delivered
to the Existing Bondholders has not closed by November 5, 2005.

FORM OF WARRANT 






 FORM OF WARRANT 
  
 CELL THERAPEUTICS, INC. 
  
 WARRANT TO PURCHASE COMMON STOCK 
  

			
	No. [    ]	 	[    ], 2005

  
 THIS CERTIFIES THAT,
[insert Existing Bondholder], a [insert jurisdiction of organization] limited partnership with its principal office located at [insert address] (the “Holder”), is entitled to subscribe for and purchase at the Exercise Price
(defined below) from Cell Therapeutics, Inc., a Washington corporation with its principal office located at 501 Elliott Avenue West, Suite 400, Seattle, Washington 98119, or its successors and assigns (the “Company”), up to [insert
number of shares as determined pursuant to Conversion and Placement Agreement] shares of the Common Stock of the Company (the “Common Stock”), subject to adjustment as provided herein. This Warrant is issued pursuant to the terms of
the Conversion and Placement Agreement, dated October 31, 2005, by and among the Company and the original Holder of this Warrant (the “CAP Agreement”). 
  
 1. Definitions. As used herein, the following terms shall have the following respective meanings: 
  
 1.1 “Business Day” means any day other than
Saturday, Sunday or other day on which commercial banks in The City of New York are authorized or required by law to remain closed. 
  
 1.2 “Exercise Period” shall mean the period commencing the date hereof and ending October 31, 2010, unless sooner
terminated as provided below. 
  
 1.3
“Exercise Price” shall mean zero ($0.00) per share. 
  
 1.4 “Exercise Shares” shall mean the shares of the Company’s Common Stock issued upon exercise of this Warrant, subject to adjustment pursuant to the terms herein, including but not limited to
adjustment pursuant to Section 5 below. 
  
 2. Exercise of
Warrant. 
  
 2.1 Method of Exercise. The
rights represented by this Warrant may be exercised in whole or in part at any time during the Exercise Period, by delivery of the following to the Company at its address set forth above (or at such other address as it may designate by notice in
writing to the Holder) and in accordance with the notice provisions of Section 11: 
  
 (i) An executed Notice of Exercise in the form attached hereto; and 
  
 (ii) This Warrant. 
  

Upon the exercise of the rights represented by this Warrant, shares of Common Stock shall be issued for the Exercise Shares so purchased, and shall be
registered in the name of the 

  

 A-1 







 
Holder or persons affiliated with the Holder, if the Holder so designates, on or before the third Business Day (the “Share Delivery Date”)
following the date on which after the rights represented by this Warrant shall have been so exercised and shall be issued in certificate form and delivered to the Holder, if so requested. 
  
 The person in whose name any Exercise Shares are to be issued upon exercise of this Warrant shall be deemed to have become
the holder of record of such shares on the date on which this Warrant was surrendered, irrespective of the date of issuance of the shares of Common Stock, except that, if the date of such surrender and payment is a date when the stock transfer books
of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open. 
  
 In lieu of delivering physical certificates representing the Exercise Shares
issuable upon conversion of this Warrant, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”) program, upon request of the Holder, the
Company shall use its best efforts to cause its transfer agent to electronically transmit the Exercise Shares issuable upon exercise to the Holder, by crediting the account of the Holder’s prime broker with DTC through its Deposit Withdrawal
Agent Commission (“DWAC”) system. The time periods for delivery described above shall apply to the electronic transmittals through the DWAC system. The Company agrees to coordinate with DTC to accomplish this objective and to use
reasonable efforts to maintain its participation in the DTC FAST program. 
  
 2.2 Partial Exercise. If this Warrant is exercised in part only, the Company shall, upon surrender of this Warrant, execute and deliver, within ten (10) Business Days of the date of exercise, a new
Warrant evidencing the rights of the Holder, or such other person as shall be designated in the Notice of Exercise, to purchase the balance of the Exercise Shares purchasable hereunder. In no event shall this Warrant be exercised for a fractional
Exercise Share, and the Company shall not distribute a Warrant exercisable for a fractional Exercise Share. Fractional Exercise Shares shall be treated as provided in Section 6 hereof. 
  
 2.3 Restriction on Exercise. In no event shall this Warrant be
exercised in whole or in part to the extent that as a result of such exercise, the Holder would thereby become the beneficial owner (as such term is defined in Rule 13d-3 of the rules and regulations promulgated under the Securities Exchange
Act of 1934, as amended, or any other applicable provision under any federal securities laws, rules or regulations that may govern what constitutes a beneficial owner for purposes of determining reporting obligations and/or a person’s or
entity’s constituting an affiliate of the Company) of more than 9.5% of the outstanding shares of Common Stock of the Company on a fully-diluted basis immediately following exercise of this Warrant. 
  
 3. Covenants of the Company. 
  
 3.1 Covenants as to Exercise Shares. The
Company covenants and agrees that all Exercise Shares that are issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free 

  

 A-2 







 
from all taxes, charges and liens with respect to the issuance thereof, and the Company further agrees to pay all taxes and charges and remove all liens that
may exist upon issuance in violation hereof. The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized and reserved, free from preemptive rights, such number of shares of Common Stock as
would be required to be issued upon the exercise of all of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but unissued shares of Common Stock shall not be sufficient to permit exercise of
this Warrant, the Company will immediately take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock (or other securities as provided herein) to such number of
shares as shall be sufficient for such purposes. 
  
 3.2 No Impairment. Except and to the extent as waived or consented to by the Holder in writing or otherwise in accordance with Section 11 hereof, the Company will not, by amendment of its Articles of Incorporation (as
such may be amended from time to time), or through any means, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying
out of all the provisions of this Warrant and in the taking of all such action as may be necessary or appropriate in order to protect the exercise rights of the Holder against impairment. Provided that the Holder shall have compiled with all the
material terms and conditions of this Warrant, the Company’s obligations to issue and deliver Exercise Shares in accordance with the terms hereof are absolute and unconditional. 
  
 3.3 Representation of Holder. The Holder acknowledges that the Warrant and the Exercise Shares
are restricted securities within the meaning of the CAP Agreement. 
  
 4. Adjustment of Number, Class and Kind of Shares Issuable. 
  
 4.1 Adjustments of Number of Warrant Shares. The number and kind of securities purchasable upon the exercise of this Warrant shall be subject to adjustment from time to time upon the happening of any of
the following. In case the Company shall (i) pay a dividend in shares of Common Stock or make a distribution in shares of Common Stock to holders of its outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock into a
greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, or (iv) issue any shares of its capital stock in a reclassification of the Common Stock, then the number of
Exercise Shares purchasable upon exercise of this Warrant immediately prior thereto shall be adjusted so that the Holder shall be entitled to receive the kind and number of Exercise Shares or other securities of the Company which it would have owned
or have been entitled to receive had such Warrant been exercised in advance thereof. Upon each such adjustment of the kind and number of Exercise Shares or other securities of the Company which are purchasable hereunder, the Holder shall thereafter
be entitled to purchase the number of Exercise Shares or other securities resulting from such adjustment at the Exercise Price. An adjustment made pursuant to this paragraph shall become effective immediately after the effective date of such event
retroactive to the record date, if any, for such event. 
  
 4.2 Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets. In case the Company shall reorganize its capital, reclassify its capital 

  

 A-3 







 
stock, consolidate or merge with or into another corporation (where the Company is not the surviving corporation or where there is a change in or
distribution with respect to the Common Stock of the Company), or sell, transfer or otherwise dispose of all or substantially all its property, assets or business to another corporation and, pursuant to the terms of such reorganization,
reclassification, merger, consolidation or disposition of assets, shares of common stock of the successor or acquiring corporation, or any cash, shares of stock or other securities or property of any nature whatsoever (including warrants or other
subscription or purchase rights) in addition to or in lieu of common stock of the successor or acquiring corporation (“Other Property”), are to be received by or distributed to the holders of Common Stock of the Company, then the Holder
shall have the right but not the obligation thereafter to receive, at the option of the Holder upon exercise of this Warrant, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving
corporation, and Other Property receivable upon or as a result of such reorganization, reclassification, merger, consolidation or disposition of assets by a Holder of the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such event. In case of and as a precondition to the consummation of any such reorganization, reclassification, merger, consolidation or disposition of assets, the successor or acquiring corporation (if other than the Company)
shall expressly assume the due and punctual observance and performance of each and every covenant and condition of this Warrant to be performed and observed by the Company and all the obligations and liabilities hereunder, subject to such
modifications as may be deemed appropriate (as determined in good faith by resolution of the Board of Directors of the Company) in order to provide for adjustments of Exercise Shares for which this Warrant is exercisable which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 4.2. For purposes of this Section 4.2, “common stock of the successor or acquiring corporation” shall include stock of such corporation of any class which
is not preferred as to dividends or assets over any other class of stock of such corporation and which is not subject to redemption and shall also include any evidences of indebtedness, shares of stock or other securities which are convertible into
or exchangeable for any such stock, either immediately or upon the arrival of a specified date or the happening of a specified event and any warrants or other rights to subscribe for or purchase any such stock. The foregoing provisions of this
Section 4.2 shall similarly apply to successive reorganizations, reclassifications, mergers, consolidations, spin-offs, or dispositions of assets. 
  
 4.3 Notice of Adjustment. Whenever the number of Exercise Shares or number or kind of securities or other property
purchasable upon the exercise of this Warrant is adjusted, as herein provided, the Company shall give notice thereof to the Holder, which notice shall state the number of Exercise Shares (and other securities or property) purchasable upon the
exercise of this Warrant after such adjustment, setting forth a brief statement of the facts requiring such adjustment and setting forth the computation by which such adjustment was made. 
  
 5. Fractional Shares. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any
adjustment pursuant hereto. All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after
aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from
multiplying the then current fair market value of an Exercise Share by such fraction. 
  

 A-4 







 6. Certain Events. In the event of, at any time during the Exercise Period, any capital
reorganization, or any reclassification of the capital stock of the Company (other than a change in par value or from par value to no par value or no par value to par value or as a result of a stock dividend or subdivision, split-up or combination
of shares), or the consolidation or merger of the Company with or into another corporation (other than a merger solely to effect a reincorporation of the Company into another state), or the sale or other disposition of all or substantially all of
the properties and assets of the Company and its subsidiaries, taken as a whole, in its entirety to any other person, other than sales or other dispositions that do not require stockholder approval (each, an “Event”), the Company shall
provide to the Holder ten days’ advance written notice of such Event; provided, however, that in no event shall the Company or its representatives be required to provide the Holder with any material non-public information. This Warrant will be
binding upon the successors and assigns of the Company upon an Event. 
  
 7. No Shareholder Rights. This Warrant in and of itself shall not entitle the Holder to any voting rights or other rights as a shareholder of the Company. 
  
 8. Lost, Stolen, Mutilated or Destroyed Warrant. Upon receipt by the issuer of evidence satisfactory to it of the
loss, theft, destruction or mutilation of this Warrant (which shall, in the case of a mutilated Warrant, include the surrender thereof) and reasonably satisfactory indemnification, issue a new Warrant of like denomination and tenor as the Warrant so
lost, stolen, mutilated or destroyed. 
  
 9. Notices, etc.
All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed email, telex or facsimile if sent during normal
business hours of the recipient, if not, then on the next business day, (c) five days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one business day after deposit with a
nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the Company at the address listed on the signature page and to the Holders at the addresses on the
Company records, or at such other address as the Company or Holder may designate by ten days’ advance written notice to the other party hereto. In the event of an exercise of the warrant pursuant to Section 2.1 above, the Holder shall

 A-5 







 
New York without regard to the principles of conflict of laws. Each party to this Warrant consents to the exclusive jurisdiction of the state and federal
courts sitting in New York County, New York in connection with any suit, action or proceeding arising out of or relating to this Warrant, and hereby waives, to the maximum extent permitted by law, any objection, including any objection based on
forum non conveniens, to the bringing of any such proceeding in either of such jurisdictions. Each party to this Warrant irrevocably consents to the service of process in any such proceeding by the mailing of copies thereof by registered or
certified mail, postage prepaid, to such party at its address in accordance with the notice provisions of this section. Nothing herein shall affect the right of any party to serve process in any other manner permitted by law. Each party to this
Warrant waives its right to a trial by jury. 
  
 12.
Modification and Waiver. This Warrant and any provisions hereof may be changed, waived, discharged or terminated only with the written consent of the Company and the Holder hereof. Any amendment effected in accordance with this paragraph
shall be binding upon the Holder, each future Holder of this Warrant and the Company. No waivers of, or exceptions to, any term, condition or provision of this Warrant, in any one or more instances, shall be deemed to be, or construed as, a further
or continuing waiver or such term, condition or provision. 
  
 13.
Descriptive Headings. The descriptive headings of the several paragraphs of this Warrant are inserted for convenience only and do not constitute a part of this Warrant. The language in this Warrant shall be construed as to its fair meaning
without regard to which party drafted this Warrant.

Severability. The invalidity or unenforceability of any provision of this Warrant in any jurisdiction shall not affect the validity or enforceability of such provision in any other jurisdiction, or affect any other provision of this Warrant,

 3. Registration Procedures. 
  
 In connection with
the Shelf Registration Statement, the following provisions shall apply: 
  
 3.1 (i) not less than 30 calendar days prior to the time the Company in good faith intends to have the initial Shelf Registration Statement declared effective, the Company shall distribute the Notice and Questionnaire
to the Holders of Registrable Securities. The Company shall take action to name as a selling securityholder in the initial Shelf Registration Statement at the Effective Time each Holder that completes, executes and delivers a Notice and
Questionnaire to the Company (a “Notice Holder”) prior to or on the 20th calendar day after such Holder’s receipt thereof so that such Holder is permitted to deliver the Prospectus forming a part thereof to purchasers of
such Holder’s Registrable Securities in accordance with applicable law. The Company shall not be required to take any action to name any Holder as a selling securityholder in the initial Shelf Registration Statement at the time of its
effectiveness or to enable any Holder to use the Prospectus forming a part thereof for resales of Registrable Securities unless such Holder has returned a completed and signed Notice and Questionnaire to the Company in a timely manner. 

 
 (ii) After the Effective Time of the initial Shelf
Registration Statement, the Company shall, upon the request of any Holder of Registrable Securities that is not then a Notice Holder, promptly send a Notice and Questionnaire to such Holder. After the Effective Time of the initial Shelf Registration
Statement, the Company shall (A) as promptly as practicable, after the date a completed and signed Notice and Questionnaire is delivered to the Company, and in any event within five Business Days or, if the Company is required to file with


  

 B-4 







 
the Commission a new Shelf Registration, 30 calendar days, after such date, prepare and file with the Commission (1) a supplement to the Prospectus or,
if required by applicable law, a post-effective amendment to the Shelf Registration Statement or an additional Shelf Registration Statement, and (2) any other document required by applicable law, so that the Holder delivering such Notice and
Questionnaire is named as a selling securityholder in a Shelf Registration Statement and is permitted to deliver the Prospectus to purchasers of such Holder’s Registrable Securities in accordance with applicable law, and (B) use its
reasonable best efforts to cause any post-effective amendment or such additional Shelf Registration Statement to become effective under the Securities Act as promptly as is practicable; but in any event by the date that is (i) 10 Business Days
after the date of such post-effective amendment, or (ii) 45 calendar days after the date such additional Shelf Registration Statement is required to be filed; provided, however, that if a Notice and Questionnaire is delivered to the Company
during a Suspension Period, the Company shall not be obligated to take the actions set forth in this clause (ii) until the termination of such Suspension Period. 
  
 3.2 The Company shall furnish to each Notice Holder and their counsel no fewer than one Business Day prior
to the initial filing of the Shelf Registration Statement a copy of such Shelf Registration Statement, and shall furnish to the Holders and counsel to the Holders no fewer than one Business Day prior to the filing of any amendment to the Shelf
Registration Statement, and shall furnish to counsel to the Holders concurrently with the filing of supplements to the Prospectus, a copy of such amendment or supplement, as the case may be in each case in order to allow the Holders to review and
comment upon the Shelf Registration Statement and all amendments or supplements thereto, and shall use its reasonable efforts to reflect in each such document when so filed with the Commission such comments as the Holders and their respective
counsel reasonably may propose; provided, however, that the Company shall not file the Shelf Registration Statement or any amendment or supplement thereto in a form to which counsel to the Holders reasonably object and will not request
acceleration of the Shelf Registration Statement or any amendment or supplement thereto without prior notice to such counsel; provided further, however, that the Company may assume that the Existing Holders accept the Shelf Registration
Statement as provided to them pursuant to this Section 3.2 if the Existing Holders do not notify the Company of any objection within one Business Day of their receipt of such Shelf Registration Statement; provided further,
however, that any delay in the filing of the Shelf Registration Statement caused by this review by the Holders and their respective counsel or the withholding of consent to file shall extend the date of the application of the Registration
Penalty by the number of days equal to the sum of (i) the number of Business Days beyond one Business Day that are used by the Existing Holders for such review and (ii) the corresponding number of Business Days as determined by clause (i),
but in no event less than one Business Day, so as to allow the Company to address such objections to the satisfaction of counsel to the Holders and counsel to the Company. 
  
 3.3 The Company shall promptly take such action as may be necessary so that (i) each of the Shelf
Registration Statements and any amendment or supplement thereto and the Prospectus forming a part thereof and any amendment or supplement thereto (and each report or other document incorporated therein by reference in each case) complies in all
material respects with the Securities Act and the Exchange Act and the respective rules and regulations thereunder, as in effect at any relevant time, (ii) each of the Shelf Registration Statements and any amendment or supplement thereto does
not, when it becomes effective, contain an untrue 

  

 B-5 







 
statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and
(iii) each Prospectus forming a part of any Shelf Registration Statement, and any amendment or supplement to such Prospectus, in the form delivered to purchasers of the Registrable Securities during the Effectiveness Period, does not include an
untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading. 
  
 3.4 The Company shall promptly advise each Notice Holder, and shall confirm such advice in writing if so requested by any such Notice
Holder: 
  
 (i) when the initial Shelf
Registration Statement has been filed with the Commission and when the initial Shelf Registration Statement has become effective; 
  
 (ii) when any supplement to the Prospectus, Shelf Registration Statement or post-effective amendment to a Shelf Registration has been
filed with the Commission and, with respect to a Shelf Registration Statement or any post-effective amendment, when the same has been declared effective by the Commission; 
  
 (iii) of any request by the Commission for amendments or supplements to any Shelf Registration Statement or
the Prospectus included therein or for additional information; 
  
 (iv) of the issuance by the Commission of any stop order suspending the effectiveness of any Shelf Registration Statement or the initiation of any proceedings for such purpose; 
  
 (v) of the receipt by the Company of any notification with
respect to the suspension of the qualification of the securities included in any Shelf Registration Statement for sale in any jurisdiction or the initiation of any proceeding for such purpose; and 
  
 (vi) of the happening of any event or the existence of any
state of facts that requires the making of any changes in any Shelf Registration Statement or the Prospectus included therein so that, as of such date, such Shelf Registration Statement and Prospectus do not contain an untrue statement of a material
fact and do not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (which advice shall be accompanied by an instruction to such Holders to suspend the use of the Prospectus until
the requisite changes have been made, which notice need not specify the nature of the event giving rise to such suspension). 
  
 3.5 The Company shall use its reasonable best efforts to prevent the issuance, and if issued to obtain the withdrawal at the earliest
possible time, of any order suspending the effectiveness of any Shelf Registration Statement. 
  
 3.6 The Company shall, as promptly as reasonably practicable, furnish to each Notice Holder, upon their request and without charge, at
least one conformed copy of the Shelf Registration Statement and any amendment or supplement thereto, including financial statements but excluding schedules, all documents incorporated or deemed to be incorporated therein by reference and all
exhibits (unless requested in writing to the Company by such Notice Holder). 
  

 B-6 







 3.7 The Company shall, during the Effectiveness Period, deliver to each Notice Holder,
without charge, as many copies of each Prospectus in which the Notice Holder is listed as a selling securityholder included in the applicable Shelf Registration Statement and any amendment or supplement thereto as such Notice Holder may reasonably
request; and the Company consents (except during a Suspension Period or during the continuance of any event described in Section 3.7(iii)-(vi) above, limited, in the case of Section 3.7(v), to the jurisdiction in question thereunder)
to the use of the Prospectus and any amendment or supplement thereto by each of the Notice Holders in connection with the offering and sale of the Registrable Securities covered by the Prospectus and any amendment or supplement thereto during the
Effectiveness Period. 
  
 3.8 Prior to any
offering of Registrable Securities pursuant to a Shelf Registration Statement, the Company shall (i) register or qualify or cooperate with the Notice Holders and their respective counsel in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or “blue sky” laws of such jurisdictions within the United States as any Notice Holder may reasonably request in
writing, (ii) keep such registrations or qualifications or exemptions therefrom in effect and comply with such laws so as to permit the continuance of offers and sales in such jurisdictions for so long as may be necessary to enable any Notice
Holder or underwriter, if any, to complete its distribution of Registrable Securities pursuant to such Shelf Registration Statement, and (iii) take any and all other actions necessary or advisable to enable the disposition in such jurisdictions
of such Registrable Securities; provided, however, that in no event shall the Company be obligated to (A) qualify as a foreign corporation or as a dealer in securities in any jurisdiction where it would not otherwise be required to so qualify
but for this Section 3.8, or (B) subject itself to general or unlimited service of process or to taxation in any such jurisdiction if it is not otherwise so subject. 
  
 3.9 Unless any Registrable Securities shall be in book-entry only form, the Company shall cooperate with the
Notice Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold pursuant to any Shelf Registration Statement, which certificates, if so required by any securities market or exchange
upon which any Registrable Securities are quoted or listed, shall be penned, lithographed or engraved, or produced by any combination of such methods, on steel engraved borders, and which certificates shall be free of any restrictive legends and in
such permitted denominations and registered in such names as Notice Holders may request in connection with the sale of Registrable Securities pursuant to such Shelf Registration Statement. 
  
 3.10 Upon the occurrence of any event or the existence of
any fact contemplated by paragraph 3(d)(vi) above, subject to Section 2.3 hereof, the Company shall promptly, but in any event within 10 Business Days following such occurrence or existence, prepare and file (and have declared effective) a
post-effective amendment to any Shelf Registration Statement or an amendment or supplement to the related Prospectus included therein or file any other document with the Commission so that, as thereafter delivered to purchasers of the Registrable
Securities, the Prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading. If the Company notifies the Notice Holders of the occurrence of any event
or the existence of any fact contemplated by paragraph 3(d)(vi) above, the Notice Holder shall suspend 

  

 B-7 







 
the use of the Prospectus and keep the notification provided pursuant to paragraph 3(d)(vi) above confidential until (i) such Electing Holder has
received copies of the supplemented or amended Prospectus contemplated by the preceding sentence or (ii) such Electing Holder is advised in writing by the Company that the use of the Prospectus may be resumed and has received copies of any
additional or supplemental filings that are incorporated by reference in the Prospectus. Notwithstanding the foregoing, but subject to Section 7 hereof, the Company shall not be required to amend or supplement the Shelf Registration Statement,
any related Prospectus or any document incorporated by reference for a period not to exceed an aggregate of 60 calendar days in any 12-month calendar period if the Company is in possession of material non-public information the disclosure of which
would have a material adverse effect on the business, operations, prospects, condition (financial or otherwise) of the Company and its subsidiaries, taken as a whole. 
  
 3.11 Not later than the Effective Time of a Shelf Registration Statement, the Company shall provide a CUSIP
number for the debt securities to be sold pursuant to a Shelf Registration Statement. 
  
 3.12 The Company shall comply with the Securities Act and the Exchange Act and the respective rules and regulations thereunder, as in
effect at any relevant time, and make generally available to its securityholders earnings statements (which need not be audited) satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule
promulgated under the Securities Act) no later than 90 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year), or such shorter period as required by the Securities Act and the
Exchange Act and the respective rules and regulations thereunder, as in effect at any relevant time. 
  
 3.13 The Company shall make reasonably available for inspection by one or more representatives of the Notice Holders, designated in
writing by a Majority of Holders whose Registrable Securities are included in a Shelf Registration Statement, any underwriter participating in any disposition pursuant to any Shelf Registration Statement, and any attorney, accountant or other agent
retained by such Notice Holders or any such underwriter (i) all relevant financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries, and (ii) cause the Company’s officers, directors
and employees to make available for inspection all information reasonably requested by such Notice Holders or any such underwriter, attorney, accountant or agent in connection with such Shelf Registration Statement, in each case, as is customary for
similar due diligence examinations; provided, however, that such persons shall, at the Company’s request, first agree in writing with the Company that any information that is reasonably and in good faith designated by the Company
in writing as confidential at the time of delivery or inspection, as the case may be, of such information shall be kept confidential by such persons and shall be used solely for the purposes of exercising rights under this Agreement, unless such
disclosure is made in connection with a court proceeding or required by law, or such records, information or documents become available to the public generally or through a third party without an accompanying obligation of confidentiality or the
content of such disclosure was already known and independently developed by the relevant Notice Holder; and provided further that, if the foregoing inspection and information gathering would otherwise disrupt the Company’s conduct of its
business, such inspection and information gathering shall, to the greatest extent possible, be coordinated on behalf of the Notice Holders 

  

 B-8 







 
and the other parties entitled thereto by one counsel designated by and on behalf of the Notice Holders and other parties. 
  
 3.14 The Company will use its reasonable best efforts to

customary form (if the distribution of Registrable Securities is to be made pursuant to an underwritten public offering) and such other customary agreements as may be necessary, desirable or appropriate, and taking all such other necessary actions
in connection therewith. 
  
 4. Registration Expenses.

 5. Indemnification and Contribution. 
  
 5.1 Indemnification by the Company. The Company shall
indemnify and hold harmless each Holder, each person, if any, who controls any such Holder, and the respective officers, directors, partners, employees, representatives and agents of any such Holder, or any controlling person, from and against any
loss, claim, damage, liability, cost or expense whatsoever as incurred (including, but not limited to, attorneys’ fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or
threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as any
such loss, claim, damage, liability, cost or expense (or action in respect thereof) arises out of, or is based upon, any untrue statement of a material fact contained in the Shelf Registration Statement or any amendment thereto or supplement thereof
or any related preliminary prospectus or the Prospectus or any amendment thereto or supplement thereof, or arises out of, or is based upon, the omission or alleged omission to state therein any material fact required to be stated therein or
necessary to make the statements therein not misleading; provided, however, that the Company shall not be liable to any such indemnified party in any such case to the extent that any such loss, claim, damage, liability, cost or expense
arises out of, or is based upon, any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of such
indemnified party specifically for use therein; and provided further, however, that the Company shall not be liable to any such indemnified party in any such case to the extent that such loss, claim, damage, liability, cost or expense
arises from an offer or sale by a Notice Holder of Registrable Securities during a Suspension Period, if such indemnified party is a Notice Holder that received from the Company a notice of the commencement of such Suspension Period prior to the
making of such offer or sale. The foregoing indemnity agreement is in addition to any liability that the Company may otherwise have to any indemnified party, and the Company hereby confirms that it will indemnify the indemnified party with respect
to any breach by the Company of its indemnity obligations hereunder, including in respect of the cost of enforcing this Section 5.1. The Company shall not be liable under this Section 5.1 for any settlement of any action effected without
its written consent, which shall not be unreasonably withheld; provided, however, that with respect to actions pursuant to clauses (i), (ii) and (iii) of Section 5.3, no such consent shall be required. 
  
 5.2 Indemnification by the Notice Holders. Each
Notice Holder, severally and not jointly, shall indemnify and hold harmless the Company, each other Holder, each person, if any, who controls the Company, or another Holder within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act and the respective officers, directors, partners, employees, representatives and agents of the Company, any other Holder or any controlling person, from and against any loss, claim, damage, liability, cost or
expense whatsoever as incurred (including, but not limited to, attorneys’ fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and
any and all amounts paid in settlement of any claim or 

  

 B-10 







 
litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as any such
loss, claim, damage, liability, cost or expense (or action in respect thereof) arises out of, or is based upon, any untrue statement of a material fact contained in the Shelf Registration Statement or any amendment thereto or any related preliminary
prospectus or the Prospectus or any amendment thereto or supplement thereof, or arises out of, or is based upon, the omission or alleged omission to state therein any material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission made therein was made in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such Notice Holder specifically for use therein. In no event shall the liability of any selling Notice Holder hereunder be greater in amount than the dollar amount of the proceeds received by such Notice
Holder upon the sale of the Registrable Securities pursuant to the Shelf Registration Statement giving rise to such indemnification obligation. The foregoing indemnity agreement is in addition to any liability that any Notice Holder may otherwise
have to the Company, the Initial Purchaser and any such other person, including in respect of the cost of enforcing this Section 5.2. 
  
 5.3 Notices of Claims, Etc. Promptly after receipt by an indemnified party under this Section 5 of notice of any claim or the
commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 5, notify the indemnifying party in writing of the claim or the commencement of that action;
provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under this Section 5. If any such claim or action shall be brought against an indemnified party, and it shall notify
the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel satisfactory
to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 5
for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel
to represent jointly the indemnified party and its respective officers, directors, partners, employees, representatives, agents and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be
sought by the indemnified party against the indemnifying party under this Section 5 if (i) employment of such counsel has been authorized in writing by the indemnifying party, or (ii) such indemnifying party shall not have employed
counsel satisfactory to the indemnified party to have charge of the defense of such proceeding within 30 days of the receipt of notice thereof, or (iii) such indemnified party shall have reasonably concluded that the representation of such
indemnified party and those officers, directors, partners, employees, representatives, agents and controlling persons by the same counsel representing the indemnifying party would be inappropriate under applicable standards of professional conduct
due to actual or potential differing interests between them or where there may be one or more defenses available to them that are different from, additional to or in conflict with those available to the indemnifying party, and in any such event
((i), (ii) or (iii)) the fees and expenses of such separate counsel shall be paid by the indemnifying party as incurred. It is understood that the indemnifying party shall not be liable for the fees and 

  

 B-11 







 
expenses of more than one separate firm (in addition to local counsel in each jurisdiction) for all indemnified parties in connection with any proceeding or
related proceedings. No indemnifying party shall, without the prior written consent of the indemnified parties, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened claim,
investigation, action, suit or proceeding in respect of which indemnity or contribution may be or could have been sought hereunder (whether or not the indemnified party or parties are actual or potential parties thereto) unless (A) such
settlement, compromise or judgment (1) includes an unconditional release of such indemnified party from all liability arising out of such claim, investigation, action, suit or proceeding, and (2) does not include a statement as to or an
admission of fault, culpability or failure to act by or on behalf of any indemnified party, and (B) the indemnifying party confirms in writing its indemnification obligations hereunder with respect to such settlement, compromise or judgment.

  
 5.4 Contribution. If the
indemnification provided for in this Section 5 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of the losses, claims, damages, costs, expenses or liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the
relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the registration of the Registrable Securities pursuant to the Shelf Registration, or (ii) if the allocation provided by
the foregoing clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on
the one hand and the indemnified party on the other in connection with the statements or omissions that resulted in such losses, claims, damages, costs, expenses or liabilities (or actions in respect thereof) as well as any other relevant equitable
considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or such Holder or such other indemnified party, as the case may be, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such
statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 5.4 shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this Section 5.4. The Company and the Holders agree that it would not be just and equitable if contribution pursuant to
this Section 5.4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to herein. Notwithstanding any other provision of this Section 5.4, no Holder
of the Registrable Securities shall be required to contribute any amount in excess of the amount by which the gross proceeds received by such Holder from the sale of its Registrable Securities pursuant to the Shelf Registration Statement exceeds the
amount of damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 5.4, each officer, director, partner, employee, representative or agent of an
indemnified party, and each person, if any, who 

  

 B-12 







 
controls such indemnified party within the meaning of the Securities Act or the Exchange Act, shall have the same rights to contribution as such indemnified
party and each officer, director, partner, employee, representative and agent of the Company, and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, shall have the same rights to contribution
as the Company. The Holders’ respective obligations to contribute pursuant to this Section 5.4 are several in proportion to the respective amount of Registrable Securities they have sold pursuant to a Shelf Registration Statement and not
joint. The remedies provided for in this Section 5.4 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. 
  
 5.5 Survival. The indemnity and contribution
provisions contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchaser, any underwriter, any
Holder, any officer, director, partner, employee, representative or agent of the Initial Purchaser, any underwriter, or any Holder, or any person controlling the Initial Purchaser, any underwriter or any Holder, or by or on behalf of the Company,
its officers, directors, partners, employees, representatives or agents or any person controlling the Company, and (iii) any sale of Registrable Securities pursuant to a Shelf Registration Statement. 
  
 6. Holder’s Obligations. 
  
 Each Holder agrees, by acquisition of the Registrable Securities, that no
Holder of Registrable Securities shall be entitled to sell any of such Registrable Securities pursuant to a Shelf Registration Statement or to receive a Prospectus relating thereto, unless such Holder has furnished the Company with a Notice and
Questionnaire as required pursuant to Section 3.1 hereof (including the information required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. Each Notice Holder agrees to promptly furnish to
the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Notice Holder not misleading and any other information regarding such Notice Holder and the distribution of such
Registrable Securities as may be required to be disclosed in the Shelf Registration Statement under applicable law, pursuant to comments from the Commission or as the Company may from time to time reasonably request. Any sale of any Registrable
Securities by any Notice Holder shall constitute a representation and warranty by such Notice Holder that the information relating to such Notice Holder and its plan of distribution is as set forth in the Prospectus delivered by such Notice Holder
in connection with such disposition, that such Prospectus does not, as of the time of such sale, contain any untrue statement of a material fact relating to or provided by such Notice Holder or its plan of distribution and that such Prospectus does
not, as of the time of such sale, omit to state any material fact relating to or provided by such Notice Holder or its plan of distribution necessary in order to make the statements in such Prospectus, in the light of the circumstances under which
they were made, not misleading. 
  
 7. Additional Interest.

  
 7.1 Notwithstanding any postponement of the
effectiveness of the Shelf Registration Statement pursuant to Section 2.1 hereof, if on November 30, 2005 such Shelf Registration Statement has not been declared effective, provided that such failure is not solely 

  

 B-13 







 
due to the Holder of a Registrable Security to perform its obligations set forth in Section 3.1(ii) hereof (a “Registration Default”),
then the Company will make a one time payment to Linden Advisors L.P. equal to $405,191 and to Sunrise Partners Limited Partnership equal to $775,222 (together, the “Registration Penalty”). In addition, if such Shelf Registration
Statement has not been declared effective prior to the end of each calendar month following November 2005, the Company shall be required to pay an additional interest payment in cash to the Notice Holder (“Additional Interest”), on
the last business day of each such month in an amount equal to the product of 0.25% and the closing price of the Common Stock on October 31, 2005, per Registrable Security held by such Notice Holder on such date. 
  
 7.2 In the case of a Registration Default described in
Sections 7.1(i)-(ii) above, Additional Interest, if any, shall be payable only to Notice Holders. 
  
 7.3 Any amounts to be paid as a Registration Penalty or Additional Interest pursuant to Section 7.1 shall be paid by wire transfer of
immediately available funds or by federal funds check on the first interest payment date following the date on which such Additional Interest begins to accrue. 
  

7.4 Except as provided in Section 9.1 hereof, the Additional Interest as set forth in this Section 7 shall be the exclusive
cash remedy available to the Holders of Registrable Securities for such Registration Default. 
  
 8. Rule 144. 
  
 The
Company covenants to the Holders of the Registrable Securities that the Company shall use its best efforts to timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under
Section 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 of the Securities Act) and the rules and regulations adopted by the Commission thereunder, all to the extent required from time to time to enable such
Holder to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144 under the Securities Act, as such may be amended from time to time, or any similar or successor rule or
regulation hereafter adopted by the Commission. Upon the request of any Holder of Registrable Securities in connection with that Holder’s sale pursuant to Rule 144, the Company shall deliver to such Holder a written statement as to whether it
had complied with such requirements. 
  
 9. Miscellaneous.

  
 9.1 Specific Performance. The parties
hereto acknowledge that there would be no adequate remedy at law if the Company fails to perform any of its obligations hereunder and that the Initial Purchaser and the Holders from time to time may be irreparably harmed by any such failure, and
accordingly agree that the Initial Purchaser and such Holders, in addition to any other remedy to which they may be entitled at law or in equity and without limiting the remedies available to the Notice Holders under Section 7 hereof, shall be
entitled to compel specific performance of the obligations of the Company under this Agreement in accordance with the terms and conditions of this Agreement, in any court of the United States or any State thereof having jurisdiction. 
  

 
B-14 







 9.2 Amendments and Waivers. This Agreement, including this Section 9.2, may
be amended, and waivers or consents to departures from the provisions hereof may be given, only by a written instrument duly executed by the Company and a Majority of Holders. Each Holder of Registrable Securities outstanding at the time of any such
amendment, waiver or consent or thereafter shall be bound by any amendment, waiver or consent effected pursuant to this Section 9.2, whether or not any notice, writing or marking indicating such amendment, waiver or consent appears on the
Registrable Securities or is delivered to such Holder. 
  
 9.3 Notices. All notices and other communications provided for or permitted hereunder shall be made in writing, shall be delivered by hand delivery, by telecopier, by courier guaranteeing overnight delivery or by first-class mail,

 APPENDIX A 
  
 CELL THERAPEUTICS, INC. 
  
 FORM OF NOTICE OF REGISTRATION STATEMENT AND 
 SELLING SECURITYHOLDER ELECTION AND QUESTIONNAIRE 
  
 NOTICE 
  
 Cell Therapeutics, Inc. (the “Company”) has filed, or intends shortly to file, with the Securities and Exchange Commission (the
“Commission”) a registration statement on Form S-3 or such other Form as may be available (the “Shelf Registration Statement”) for the registration and resale under Rule 415 of the Securities Act of 1933, as amended (the
“Securities Act”), of the Restricted Shares in accordance with the terms of the Registration Rights Agreement, dated as of October 31, 2005 (the “Registration Rights Agreement”), by and among the Company, Linden Capital
Partners, L.P. and Sunrise Partners Limited Partnership. All capitalized terms not otherwise defined herein have the meanings ascribed thereto in the Registration Rights Agreement. 
  
 To sell or otherwise dispose of any Restricted Shares pursuant to the Shelf Registration Statement, a beneficial owner of
Restricted Shares generally will be required to be named as a Selling Securityholder in the related Prospectus, deliver a Prospectus to purchasers of Restricted Shares, be subject to certain civil liability provisions of the Securities Act and be
bound by those provisions of the Registration Rights Agreement applicable to such beneficial owner (including certain indemnification rights and obligations, as described below). To be included in the Shelf Registration Statement, this Notice and
Questionnaire must be completed, executed and delivered to the Company at the address set forth herein for receipt prior to or on the 3rd calendar day from the receipt hereof (the “Notice and Questionnaire Deadline”). Beneficial Owners
that do not complete and return this Notice and Questionnaire prior to the Notice and Questionnaire Deadline and deliver it to the Company as provided below will not be named as Selling Securityholders in the Shelf Registration Statement and,
therefore, will not be permitted to sell any Restricted Shares pursuant to the Shelf Registration Statement. 
  
 Certain legal consequences arise from being named as a Selling Securityholder in the Shelf Registration Statement and the related Prospectus. Accordingly,
holders and beneficial owners of Restricted Shares are advised to consult their own securities law counsel regarding the consequences of being named or not being named as a Selling Securityholder in the Shelf Registration Statement and the related
Prospectus.
