CERTIFICATE OF DESIGNATIONS

SERIES B CONVERTIBLE PREFERRED STOCK

NORTHWEST BIOTHERAPEUTICS, INC.

Northwest Biotherapeutics, Inc. (the “Company”), a corporation formed and existing under the Delaware General Corporation Law (the “DGCL”), does hereby determine and certify that, pursuant to Section 151 of the DGCL and authority conferred upon its Board of Directors (the “Board of Directors”) by the Company’s Certificate of Incorporation (as amended, the “Certificate of Incorporation”), pursuant to Section 141(f) of the DGCL, the Board of Directors hereby adopt the following resolutions by unanimous written consent in lieu of a meeting:

WHEREAS, the Certificate of Incorporation authorizes 40,000,000 shares of preferred stock, par value $0.001 per share (the “Preferred Stock”); and

WHEREAS, the Certificate of Incorporation authorizes the Board of Directors to provide, by resolution from time to time and by filing a certificate of designations pursuant to the DGCL, for the issuance of the shares of Preferred Stock in one or more series;

NOW, THEREFORE, BE IT RESOLVED, that the Board of Directors hereby approves and adopts the designations set forth below (this “Certificate of Designations”) and a series of Preferred Stock with the following powers, designations, preferences and rights and the following qualifications, limitations and restrictions is hereby authorized and established:

ARTICLE 1

DESIGNATION

Section 1.1 There is hereby created out of the authorized and unissued shares of Preferred Stock of the Company a series of preferred stock designated “Series B Convertible Preferred Stock” (the “Series B Preferred Stock”), consisting of 15,000,000 shares, par value $0.001 per share (each, a “Series B Preferred Share”). Each Series B Preferred Share shall rank equally in all respects and shall be subject to the following provisions of this Certificate of Designations. Series B Preferred Shares which have been converted, redeemed, repurchased or otherwise acquired by the Company shall be retired and, following the filing of any certificate required by the DGCL, will have the status of authorized and unissued shares of the Company’s Preferred Stock, without designation as to series, until such shares are once more designated by the Board of Directors as part of a particular series of preferred stock.

- 2 -

ARTICLE 2

RANK AND PREFERENCE

Section 2.1 The Series B Preferred Stock shall, with respect to rights upon an acquisition of the Company, sale of all or substantially all assets of the Company, other business combination or liquidation, dissolution or winding up of the affairs of the Company (collectively, a “Liquidation Event”) rank senior and prior to the common stock, par value $0.001 per share, of the Company (the “Common Stock”). In the event of a Liquidation Event, each Holder shall, with respect to each Series B Preferred Share owned by such Holder, be entitled to receive, out of funds of the Company legally available therefor, before any payment or distribution of any assets of the Company shall be made or set apart for holders of the Common Stock, an amount per Series B Preferred Share equal to, at the election of the relevant such Holder, either (a) $2.30 per Series B Preferred Share or (b) the amount such Holder would have received had such Holder, immediately prior to such Liquidation Event, converted such Series B Preferred Share into shares of Common Stock as set forth herein.

ARTICLE 3

VOTING RIGHTS AND TRANSFERABILITY

Section 3.1 On any matter presented to the stockholders of the Company for their action at any meeting of stockholders of the Company (or by written consent of stockholders in lieu of a meeting), each Holder shall be entitled to cast the number of votes equal to 10 votes per Series B Preferred Share held by such Holder. Notwithstanding the foregoing, Holders of Series B Preferred Stock shall not be entitled to vote shares of such stock on any matter for which the holders of Common Stock are then entitled to vote as a separate class pursuant to Section 242(b)(2) of the DGCL (including any amendment to the Certificate of Incorporation to increase or decrease the authorized number of shares of Common Stock unless the class vote on such matter has been eliminated pursuant to the Certificate of Incorporation). Except as otherwise required by law or other provisions of the Certificate of Incorporation or this Certificate of Designations, Holders shall vote together with the holders of Common Stock as a single class (together with any other capital stock entitled to vote thereon) and shall be entitled to notice of any stockholders’ meeting in accordance with the bylaws of the Company as in effect from time to time.

Section 3.2 On or before the Voting Period End Date (as defined below), the Series B Preferred Stock shall not be directly or indirectly assignable or transferable by any Holder thereof, and no Holder of Series B Preferred Stock shall at any time, directly or indirectly, sell, assign, transfer or otherwise dispose of any shares of Series B Preferred Stock or any economic or voting interests or rights associated therewith, except as specifically authorized by the Board of Directors in its sole discretion. Any purported transfer or assignment in violation of the foregoing shall be void ab initio and given no effect. “Voting Period End Date” means the earlier of (i) the date on which the holders of the Company’s common stock approve, at a shareholder meeting of the Company, an increase in the maximum number of shares authorized for issuance, or (ii) June 1, 2018.

ARTICLE 4

CONVERSION

Section 4.1. Shares of Common Stock To Be Delivered Upon Conversion. Each Series B Preferred Share shall be convertible into ten (10) shares of Common Stock as provided in this Article 4.

- 3 -

Section 4.2 Optional Conversion. From and after the date on which the Company has sufficient shares of Common Stock authorized and available for issuance to satisfy its obligations to deliver Common Stock upon conversion of some or all of the Series B Preferred Stock, but in any event not later than six (6) months after issuance of such Series B Preferred Stock (such date, the “Convertibility Date”), each Holder shall be entitled, subject to such availability of Common Stock, to convert some or all of their Series B Preferred Stock, at any time and from time to time into a number of duly authorized, validly issued, fully paid and non-assessable shares of Common Stock as set forth in this Article 4. Upon such conversion, the Series B Preferred Shares so converted shall no longer be deemed to be outstanding, and all rights of the Holder with respect to such Series B Preferred Shares shall immediately terminate, except the right to receive the shares of Common Stock and any other amounts payable pursuant to this Certificate of Designations.

Section 4.3. Mandatory Conversion. From and after the Convertibility Date, the Company shall have the right, at any time and from time to time, in its sole discretion, to cause some or all of such Series B Preferred Shares to be automatically converted (without any further action by the Holder(s) and whether or not the Series B Preferred Shares (in the case of uncertificated shares) or the certificates representing the Series B Preferred Shares are surrendered), into a number of duly authorized, validly issued, fully paid and non-assessable shares of Common Stock as set forth in this Article 4. The Company shall exercise this right by delivering at least three (3) days’ prior written notice thereof to the applicable Holder of Series B Preferred Shares. From and after such conversions (the dates and times of such conversion, the applicable “Mandatory Conversion Date”), the Series B Preferred Shares so converted shall no longer be deemed to be outstanding, and all rights of the Holder with respect to such Series B Preferred Shares shall immediately terminate, except the right to receive the shares of Common Stock and any other amounts payable pursuant to this Certificate of Designations.

Section 4.4. Beneficial Ownership Limitation. Subject to Section 6.5, the Company shall not effect any conversion of the Series B Preferred Stock, and a Holder shall not have the right to convert any portion of the Series B Preferred Stock, to the extent that, after giving effect to an attempted conversion set forth on an applicable notice of conversion, such Holder (together with such Holder’s Affiliates, and any other Person whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act and the applicable regulations of the Commission, including any “group” of which the Holder is a member) would beneficially own a number of shares of Common Stock in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Affiliates shall include the number of shares of Common Stock issuable upon conversion of the Series B Preferred Stock subject to the applicable notice of conversion with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (A) conversion of the remaining, unconverted Series B Preferred Stock beneficially owned by such Holder or any of its Affiliates, and (B) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company (including any warrants) beneficially owned by such Holder or any of its Affiliates that are subject to a limitation on conversion or exercise similar to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this Section 4.4, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the applicable regulations of the Commission. In addition, for purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and the applicable regulations of the Commission. For purposes of this Section 4.4, in determining the number of outstanding shares of Common Stock, absent actual knowledge of such Holder to the contrary, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (A) the Company’s most recent periodic or annual filing with the Commission, as the case may be, (B) a more recent public announcement by the Company that is filed with the Commission, or (C) a more recent notice by the Company or the Company’s transfer agent to the Holder setting forth the number of shares of Common Stock then outstanding. Upon the written request of a Holder, the Company shall, within three Trading Days thereof, confirm in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to any actual conversion or exercise of securities of the Company, including shares of Series B Preferred Stock, by such Holder or its Affiliates since the date as of which such number of outstanding shares of Common Stock was last publicly reported or confirmed to the Holder. The initial “Beneficial Ownership Limitation” shall be 9.9% (after giving effect to the issuance of shares of Common Stock pursuant to such notice of conversion (to the extent permitted pursuant to this Section 4.4.)) The Company shall be entitled to rely on representations made to it by the Holder in any notice of conversion regarding its Beneficial Ownership Limitation.

- 4 -

Section 4.5. Mechanics of Conversion. In order to convert Series B Preferred Shares pursuant to Section 4.2, the converting Holder must surrender the applicable Series B Preferred Shares (in the case of uncertificated shares) or the certificates representing such Series B Preferred Shares at the office of the Company’s transfer agent for the Series B Preferred Stock (or at the principal office of the Company, if the Company serves as its own transfer agent), together with (i) written notice that such Holder elects to convert all or part of such Series B Preferred Shares as specified in such notice and (ii) a written instrument or instructions of transfer or other documents and endorsements reasonably acceptable to the transfer agent or the Company, as applicable. The date the transfer agent or the Company, as applicable, receives such Series B Preferred Shares or certificates, together with such notice and any other documents and amounts required to be paid by the Holder pursuant to this Section 4.5, will be the date of conversion.

Section 4.6. Transfer Taxes. Issuances of shares of Common Stock upon conversion of the Series B Preferred Shares shall be made without charge to the Holder for any issuance or transfer tax or other incidental expense in respect of the issuance thereof; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance or delivery of shares of Common Stock in a name other than that of the converting Holder, and no such issuance or delivery need be made unless and until the Person requesting such issuance or delivery has paid to the Company the amount of any such tax or has established, to the reasonable satisfaction of the Company, that such tax has been, or will timely be, paid.

Section 4.7. Adjustments for Subsequent Events. From and after the date of this Certificate of Designations, adjustments shall be made from time to time (but not less than the par value of the Common Stock) as follows:

(a) Stock Splits, Subdivisions, Reclassifications or Combinations. If the Company shall (i) subdivide (including by stock dividend) or reclassify the outstanding shares of Common Stock into a greater number of shares, or (ii) combine or reclassify the outstanding Common Stock into a smaller number of shares, the number of shares of Common Stock issuable upon conversion of the Series B Preferred Stock and the number of votes held by each Series B Preferred Share held by the Holders will be correspondingly adjusted.

- 5 -

(b) Other Distributions. If the Company fixes a record date for the making of a dividend or distribution to all holders of shares of its Common Stock (i) of cash, (ii) of shares of any class of the Company or of any Person, other than shares of the Company’s Common Stock, or (iii) of evidences of indebtedness of the Company or any subsidiary, (iv) of assets or (v) of rights or warrants in respect of any of the foregoing, in each such case the Series B Preferred Stock shall be entitled to receive such dividend of distribution on an as-converted basis.

(c) Successive Adjustments. Successive adjustments in respect of the Series B Preferred Shares shall be made pursuant to this Section 4.7, without duplication, whenever any event specified in Section 4.7(a) hereof shall occur.

(d) Rounding of Calculations; Minimum Adjustments. All calculations of any share adjustment amount under this Section 4.7 shall be made to the nearest one-thousandth (1/1,000th). No adjustment is required if the amount of such adjustment would be less than 0.01 of a share; provided, however, that any adjustments which by reason of this Section 4.7(d) are not required to be made will be carried forward and given effect in any subsequent adjustment.

(d) “Exercise Period” shall mean the period commencing on the Exercisability Date and ending two (2) years after the Exercisability Date.

(e) “Exercise Price” of this Warrant shall be Twenty-Two Cents ($0.22) per share.

2. Exercise of Warrant.

2.1 Vesting and Exercise. This Warrant will be fully vested upon issuance, but will not be exercisable prior to the Exercisability Date. Subject to the preceding limitation on exercise and the conditions set forth in this Warrant, the rights represented by this Warrant may be exercised in whole or in part at any time or times prior to the expiration of 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):

(a) An executed Notice of Exercise in the form attached hereto;

(b) Payment of the Exercise Price by wire transfer of immediately available funds, subject to Paragraph 2.2 below; and

Upon the exercise of the rights represented by this Warrant, a certificate or certificates for the Exercise Shares so purchased, registered in the name of the Holder or Holder’s designee(s), shall be issued and delivered to the Holder within a reasonable time after the rights represented by this Warrant shall have been so exercised (but in no event less than three (3) Trading Days following the date of exercise). In the event that this Warrant is being exercised for less than all of the then-current number of Exercise Shares purchasable hereunder, the Company shall, concurrently with the issuance by the Company of the number of Exercise Shares for which this Warrant is then being exercised, issue a new Warrant exercisable for the remaining number of Exercise Shares purchasable hereunder.

The person in whose name any certificate or certificates for 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 and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, 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.

2.2 Net (Cashless) Exercise. If and only if, and to the extent that, there is no effective registration statement registering the issuance Common Stock of the Company upon exercise of this Warrant at the time this Warrant is exercised, and if the fair market value of one Exercise Share is greater than the Exercise Price (at the date of calculation as set forth below), then in lieu of exercising this Warrant by payment of cash, the Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Notice of Exercise in which event the Company shall issue to the Holder a number of Exercise Shares computed using the following formula:

Y (A - B)

X =__________

Where X =

the number of Exercise Shares to be issued to the Holder

Y =

the number of Exercise Shares purchasable under the Warrant or, if only a portion of the Warrant is being exercised, that portion of the Warrant being canceled (at the date of such calculation)

A =

the average of the VWAP of the Common Stock for the ten consecutive Trading Days ending on the Trading Day immediately prior to the date of exercise of the Warrants

B =

Exercise Price (as adjusted to the date of such calculation)

“Trading Day” means a day on which (i) trading in Common Stock generally occurs on the principal U.S. national or regional securities exchange on which the Common Stock is then listed or, if the Common Stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which the Common Stock is then traded, which may be OTCQB or OTCQX (a “Trading Market”) and (ii) a last reported sale price for our common stock is available on such securities exchange or market. If the Common Stock is not so listed or traded, “Trading Day” means a “Business Day.”

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:00 p.m. (New York City time)), (b) if such volume weighted average price is unavailable from Bloomberg L.P. or its successor, the closing sales price of the Common Stock on the Trading Market, or (c) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

2.3 Securities for Which Warrant is Exercisable. Subject to the limitations on exercise and the conditions set forth in this Warrant, this Warrant shall be exercisable, in whole or in part, and from time to time, for Common Stock of the Company.

3. Covenants of the Company.

3.1 Covenants as to Exercise Shares. The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and non-assessable, and free from all taxes, liens and charges with respect to the issuance thereof.

3.2 No Impairment. The Holder’s rights, preferences and privileges granted under and/or in connection with this Warrant may not be amended, modified or waived without the Holder’s prior written consent.

4. Representations of Holder.

4.1 Acquisition of Securities for Personal Account. The Holder represents and warrants that the securities it is acquiring on the date hereof are being acquired solely for its account for investment and not with a view to or for sale or distribution of such securities, or any part thereof, except in compliance with applicable federal and state securities laws. The Holder also represents and warrants that all of the legal and beneficial interests in the securities which the Holder is acquiring are being acquired for, and will be held for, its account only.

4.2 Accredited Investor Status. The Holder is an “accredited investor” as defined in Regulation D promulgated under the Act.

5. Adjustment of Exercise Price and Exercise Shares.

5.1 Changes in Securities. In the event of changes in the Common Stock by reason of stock dividends, splits, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like, the aggregate number of Exercise Shares then available under the Warrant and the Exercise Price thereof shall be correspondingly adjusted to give the Holder of the Warrant, on exercise for the same aggregate Exercise Price, the same shares as the Holder would have owned had the Warrant been exercised prior to the event and had the Holder continued to hold such shares until after the event requiring adjustment. The form of this Warrant need not be changed because of any adjustment in the number of Exercise Shares subject to this Warrant. Notwithstanding anything in this Warrant to the contrary, no adjustment will be made to the Exercise Price of this Warrant, such that the Exercise Price would be less than the then current par value of outstanding shares of Common Stock.

6. 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) to be issued upon exercise of this Warrant shall 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 one Exercise Share by such fraction.

7. Transfer of Warrant.

a) Transferability. On or before the Voting Period End Date (as defined below), the Class D-1 Warrants shall not be directly or indirectly assignable or transferable by the Holder, and the Holder shall not at any time, directly or indirectly, sell, assign, transfer or otherwise dispose of, loan or pledge any Class D-1 Warrants or any economic or voting interests or rights associated therewith, except as specifically authorized by the Board of Directors in its sole discretion. Any purported transfer or assignment in violation of the foregoing shall be void ab initio and given no effect. After the Voting Period End Date, this Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. “Voting Period End Date” means the 80th day after the conclusion of the Company’s 2017 annual meeting of stockholders. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Business Days of the date on which the Holder delivers an assignment form to the Company assigning this Warrant full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Exercise Shares without having a new Warrant issued.

b) New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 7(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the date of the original issuance of the Warrant and shall be identical with this Warrant except as to the number of Exercise Shares issuable pursuant thereto.

c) Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

8. Lost, stolen, mutilated or destroyed warrant. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnification by the Holder or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a replacement Warrant of the same denomination and tenor as the Warrant so lost, stolen, mutilated or destroyed. Upon the issuance of any such replacement Warrant, the original Warrant shall become null and void without the necessity of any further action on the part of the Company.

9. Amendment. Any term of this Warrant may be amended or waived only with the advance written consent of the Company and the Holder.

10. Notices, Etc. All notices required or permitted hereunder shall be in writing and shall be effective upon delivery to the recipient. All communications shall be sent to the Company and to the Holder at the addresses listed on the signature page hereof or at such other address as the Company or Holder may designate by written notice to the other parties hereto.

11. Governing Law. This Warrant and all rights, obligations and liabilities hereunder shall be governed by and construed under the laws of the State of Delaware without giving effect to conflicts of laws principles.
