LOAN AGREEMENT and
PROMISSORY NOTE

US $1 million		August 19, 2008

SECTION 1. GENERAL.

Toucan Partners, LLC, a Delaware limited liability company (“Toucan Partners” or the “Holder”) hereby grants to Northwest Biotherapeutics, Inc., a Delaware corporation (the “Maker” or the “Company”), an unsecured bridge term loan facility of One Million Dollars (US$1.0 million) (the “Principal Amount”) subject to the terms of this Loan Agreement and Promissory Note (this “Note”). The funding at closing of this Note will be US$1.0 million, and the repayment on the Maturity Date will be US$1,060,000.00 (the “Repayment Amount”). The Repayment Amount minus the Principal Amount shall constitute original issue discount (“OID”). At the Maturity Date, up to US$60,000 of the Repayment Amount may, at the election of the Holder in its sole discretion, be paid in common stock of the Company on the terms set forth in this Note (including, without limitation, the pricing set forth in Section 11 hereof). Toucan Partners shall forthwith following execution of this Note advance the Principal Amount to the Company at the account notified to Toucan Partners by the Company.

Following receipt of the Principal Amount and for value received, the Company hereby promises to pay the Repayment Amount to the order of the Toucan Partners or its assigns, in accordance with this Note, on February 19, 2009, or such earlier date as may be applicable under Sections 3 and 4 hereof (the “Maturity Date”).

SECTION 2. PRE-PAYMENT.

This Note may be pre-paid in whole or in part prior to the Maturity Date, at the election of the Maker. Any such pre-payment shall have no effect upon the Repayment Amount.

SECTION 3. DEFAULT PAYMENT.

Upon the occurrence of an Event of Default (as defined in Section 4 hereof) after notice as provided in Section 17.1 hereof (“Event of Default”), default payments shall become due and payable on any unpaid Repayment Amount that remains outstanding after the applicable Maturity Date (the “Default Principal”). The default payments shall be assessed on a monthly basis at the beginning of each month or partial month in which any Default Principal remains outstanding. Such default payments shall be a fixed amount relating to such month or partial month, and shall not be pro rated if the Default Principal is repaid by the Maker during such month. The amount of such default payments shall be equal to the lowest of (i) 0.25% percent of the Default Principal per month or partial month that such Default Principal remains outstanding, representing an annualized rate of Default Payments of three percent (3%) per annum, or (ii) the maximum rate permitted under applicable rules and regulations of the United States Small Business Administration (the “SBA”), or (iii) the maximum rate allowed by law (the “Default Payments”). Such Default Payments shall commence upon the occurrence of an Event of Default and continue until such Event of Default is fully cured or waived. The Default Payments shall be paid in common stock of the Company, at a price per share as provided in Section 11 hereof.

SECTION 4. DEFAULTS.

4.1 Definitions. Each occurrence of any of the following events shall constitute an “Event of Default”:

(b) if any representation or warranty of Maker made herein shall have been false or misleading in any material respect, or shall have contained any material omission, as of the date hereof;

(c) if a material default occurs in the due observance or performance on the part of Maker of any covenant or agreement to be observed or performed pursuant to the terms of this Note and such default remains uncured for ten (10) business days after written notice thereof from Holder;

(e) if there shall be filed against Maker an involuntary petition seeking reorganization of Maker or the appointment of a receiver, trustee, custodian or liquidator of Maker or a substantial part of its assets, or an involuntary petition under any bankruptcy, reorganization or insolvency law of any jurisdiction, whether now or hereafter in effect (any of the foregoing petitions being hereinafter referred to as an “Involuntary Petition”) and such Involuntary Petition shall not have been dismissed within ninety (90) days after it was filed;

4.2 Remedies on Default.

(a) Upon each and every such Event of Default and at any time thereafter during the continuance of such Event of Default: (i) any and all indebtedness and related amounts (including, without limitation, Default Payments) due from Maker to Holder under this Note or otherwise shall immediately become due and payable; and (ii) Holder may exercise all the rights of a creditor under applicable law.

(b) In case any one or more Events of Default shall occur and be continuing, and acceleration of this Note or any other indebtedness or obligation of Maker to Holder shall have occurred, Holder may, inter alia, proceed to protect and enforce its rights by an action at law, suit in equity and/or other appropriate proceeding, whether for the specific performance of any agreement contained in this Note, or for an injunction against a violation of any of the terms hereof or thereof or in furtherance of the exercise of any power granted hereby or thereby or by law. No right conferred upon Holder by this Note shall be exclusive of any other right referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise.

SECTION 5. DEFENSES.

5.1 No Offsets. The obligations of Maker under this Note shall not be subject to reduction, limitation, impairment, termination, defense, set-off, counterclaim or recoupment for any reason.

9.2 Actions of Holder not a Waiver.

Final judgment in any such suit, action, or proceeding brought in any such court shall be conclusive and binding upon Maker and may be enforced in any court in which Maker is subject to jurisdiction by a suit upon such judgment, provided that service of process is effected upon Maker as provided in this Note or as otherwise permitted by applicable law.

Maker hereby consents to process being served in any suit, action, or proceeding instituted in connection with this Note by delivery of a copy thereof by certified mail, postage prepaid, return receipt requested, to Maker, and/or by delivery of a copy thereof to a registered agent of Maker. Refusal to accept delivery, and/or avoidance of delivery, shall be deemed to constitute delivery. Maker irrevocably agrees that service in accordance with this Section 9.5 shall be deemed in every respect effective service of process upon Maker in any such suit, action or proceeding, and shall, to the fullest extent permitted by law, be taken and held to be valid personal service upon Maker. Nothing in this Section 9.5 shall affect the right of Holder to serve process in any manner otherwise permitted by law or limit the right of Holder otherwise to bring proceedings against Maker in the courts of any jurisdiction or jurisdictions.

SECTION 14. PIGGYBACK REGISTRATION RIGHTS.

14.1 Piggyback Registrations. The Company shall notify the Holder in writing at least fifteen (15) business days prior to the filing of any registration statement under the Securities Act for purposes of a public offering of securities of the Company (other than registration statements relating to employee benefit plans or with respect to corporate reorganizations or other transactions under Rule 145 of the Securities Act), and shall afford the Holder an opportunity to include in such registration statement all or part of the shares of common stock issued pursuant to Section 11 hereof and held at such time by Holder (the “Registrable Securities”).

(a) In addition to all rights and remedies available to Holder at law or in equity, Maker shall, to the fullest extent permitted by law, indemnify Holder and each subsequent holder of this Note, and their respective affiliates, stockholders, limited partners, general partners, officers, directors, managers, employees, agents, representatives, successors and assigns (collectively, the “Indemnified Persons”) and pay on behalf of or reimburse such party for any losses, damages, or expenses, including, without limitation, reasonable attorneys’ fees and all amounts paid in investigation, defense or settlement of any of the foregoing which any Indemnified Person may suffer, sustain or become subject to as a result of or in connection with any material misrepresentation in, or material omission from, any of the representations and warranties, or any material breach of any covenant or agreement on the part of Maker under this Note; provided, however, that notwithstanding the foregoing or any other agreement to the contrary, in no event shall Maker be liable for indirect or consequential losses or damages of any kind, and in no event shall Maker be liable for any losses or damages resulting from the Holder’s or any other Indemnified Person’s gross negligence, willful misconduct, lack of good faith, or breach of such person’s duty of loyalty to the Maker (if any). Notwithstanding any other provision of this Agreement, the Maker shall not be obligated pursuant to the terms of this Agreement to indemnify Holder or another Indemnified Person for acts, omissions or transactions from which such Indemnified Person may not be indemnified under applicable law.

(b) Within five (5) business days after receipt of notice of commencement of any action or the assertion of any claim by a third party, Holder shall give Maker written notice thereof together with a copy of such claim, process or other legal pleading of such claim. Maker shall have the right to assist in the defense thereof by representation of its own choosing, at its own expense. Maker shall not be liable under this Agreement to make any payment to Holder or another Indemnified Person in connection with the indemnification provisions set forth in sub-paragraph (a) of this Section 15.1 to the extent Holder or such other Indemnified Person has otherwise actually received payment (under any insurance policy or otherwise) of the amounts otherwise indemnifiable hereunder. Both the Maker and Holder acknowledge that in certain instances, federal law or applicable public policy may prohibit the Maker from indemnifying Holder or other Indemnified Persons under this Agreement or otherwise. Holder understands and acknowledges that the Maker has undertaken or may be required in the future to undertake with the Securities and Exchange Commission to submit the question of indemnification to a court in certain circumstances for a determination of the Maker’s right under public policy to indemnify Holder or other Indemnified Persons.

15.2 Survival. All indemnification rights hereunder shall survive the execution and delivery of this Note and the consummation of the transactions contemplated hereunder, for a period of two (2) years, regardless of any investigation, inquiry or examination made for or on behalf of, or any knowledge of Holder and/or any of the Indemnified Persons, or the acceptance by Holder of any certificate or opinion.
