Shares of 
 Common Stock 

As Herein Described 

                    , 2015 

WARRANT TO PURCHASE COMMON STOCK OF 

CYTODYN INC. 
 This is to
certify that, for value received,                          or a proper assignee (the “Holder”), is entitled to purchase
up to                      shares (“Warrant Shares”) of common stock, no par value per share (the “Common Stock”), of CytoDyn
Inc., a Colorado corporation (the “Company”), subject to the provisions of this Warrant Number A-            , from the Company. This Warrant shall be exercisable at
seventy-five cents ($0.75) per share (the “Exercise Price”). This Warrant also is subject to the following terms and conditions: 

1. Exercise and Payment; Exchange. 

(a) This Warrant may be exercised in whole or in part at any time from and after the date hereof (the “Commencement Date”) through
5:00 p.m., Pacific time, on                     ,2020 (the “Expiration Date”), at which time this Warrant shall expire and become
void, but if such date is a day on which federal or state chartered banking institutions located in the State of Washington are authorized to close, then on the next succeeding day which shall not be such a day. Exercise shall be by presentation and
surrender to the Company, or at the office of any transfer agent designated by the Company (the “Transfer Agent”), of (i) this Warrant, (ii) the attached exercise form properly executed, and (iii) a certified or official
bank check for the 







 
Exercise Price for the number of Warrant Shares specified in the exercise form. If this Warrant is exercised in part only, the Transfer Agent shall, upon surrender of the Warrant, execute and
deliver a new Warrant evidencing the rights of the Holder to purchase the remaining number of Warrant Shares purchasable hereunder. Upon receipt by the Company of this Warrant in proper form for exercise, accompanied by payment as aforesaid, the
Holder shall be deemed to be the holder of record of the Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing such Warrant Shares shall not then
be actually delivered by the Holder. 
 (b) Conditions to Exercise or Exchange. The restrictions in Section 7 shall apply, to
the extent applicable by their terms, to any exercise or exchange of this Warrant permitted by this Section 1. 
 2. Reservation of
Shares. The Company shall, at all times until the expiration of this Warrant, reserve for issuance and delivery upon exercise of this Warrant the number of Warrant Shares which shall be required for issuance and delivery upon exercise of this
Warrant. 
 3. Fractional Interests. The Company shall not issue any fractional shares or scrip representing fractional shares upon
the exercise or exchange of this Warrant. With respect to any fraction of a share resulting from the exercise or exchange hereof, the Company shall pay to the Holder an amount in cash equal to such fraction multiplied by the current fair market
value per share of Common Stock, determined as follows: 
 (a) If the Common Stock is listed on a national securities exchange or admitted
to unlisted trading privileges on such an exchange, the current fair market value shall be the last reported sale price of the Common Stock on such exchange on the last business day prior to the date of exercise of this Warrant or if no such sale is
made on such day, the mean of the closing bid and asked prices for such day on such exchange; 
 (b) If the Common Stock is not so listed or
admitted to unlisted trading privileges or quoted on a national securities exchange, the current fair market value shall be the mean of the last bid and asked prices reported on the last business day prior to the date of the exercise of this Warrant
by the OTC Markets Group, Inc.; or 
 (c) If the Common Stock is not so listed or admitted to unlisted trading privileges and bid and asked
prices are not so reported, the current fair market value shall be an amount, not less than book value, determined in such reasonable manner as may be prescribed by the Company in good faith. 

4. No Rights as Shareholder. This Warrant shall not entitle the Holder to any rights as a shareholder of the Company, either at law or
in equity. The rights of the Holder are limited to those expressed in this Warrant and are not enforceable against the Company except to the extent set forth herein. 

5. Adjustments in Number and Exercise Price of Warrant Shares. 

5.1 The number of shares of Common Stock for which this Warrant may be exercised and the Exercise Price therefor shall be subject to
adjustment as follows: 
 (a) If the Company is recapitalized through the subdivision or combination of its outstanding shares of Common
Stock into a larger or smaller number of shares, the number of shares of Common Stock for which this Warrant may be exercised shall be increased or reduced, as of the record date for such recapitalization, in the same proportion as the increase or
decrease in the outstanding shares of Common Stock, and the Exercise Price shall be adjusted so that the aggregate amount payable for the purchase of all of the Warrant Shares issuable hereunder immediately after the record date for such
recapitalization shall equal the aggregate amount so payable immediately before such record date. 

  
 2 








 (b) If the Company declares a dividend on Common Stock payable in Common Stock or securities
convertible into Common Stock, the number of shares of Common Stock for which this Warrant may be exercised shall be increased as of the record date for determining which holders of Common Stock shall be entitled to receive such dividend, in
proportion to the increase in the number of outstanding shares (and shares of Common Stock issuable upon conversion of all such securities convertible into Common Stock) of Common Stock as a result of such dividend, and the Exercise Price shall be
adjusted so that the aggregate amount payable for the purchase of all the Warrant Shares issuable hereunder immediately after the record date for such dividend shall equal the aggregate amount so payable immediately before such record date. 

(c) If the Company distributes to holders of its Common Stock, other than as part of its dissolution or liquidation or the winding up of its
affairs, any shares of its Common Stock, any evidence of indebtedness or any of its assets (other than cash, Common Stock or securities convertible into Common Stock), the Company shall give written notice to the Holder of any such distribution at
least fifteen (15) days prior to the proposed record date in order to permit the Holder to exercise this Warrant on or before the record date. There shall be no adjustment in the number of shares of Common Stock for which this Warrant may be
exercised, or in the Exercise Price, by virtue of any such distribution. 
 (d) If the Company offers rights or warrants to the holders of
Common Stock which entitle them to subscribe to or purchase additional Common Stock or securities convertible into Common Stock, the Company shall give written notice of any such proposed offering to the Holder at least fifteen (15) days prior
to the proposed record date in order to permit the Holder to exercise this Warrant on or before such record date. There shall be no adjustment in the number of shares of Common Stock for which this Warrant may be exercised, or in the Exercise Price,
by virtue of any such distribution. 
 (e) If the event, as a result of which an adjustment is made under paragraph (a) or
(b) above, does not occur, then any adjustments in the Exercise Price or number of shares issuable that were made in accordance with such paragraph (a) or (b) shall be adjusted to the Exercise Price and number of shares as were in
effect immediately prior to the record date for such event. 
 5.2 In the event of any reorganization or reclassification of the outstanding
shares of Common Stock (other than a change in par value or from no par value to par value, or from par value to no par value, or as a result of a subdivision or combination) or in the event of any consolidation or merger of the Company with another
entity after which the Company is not 

  
 3 








 
the surviving entity, at any time prior to the expiration of this Warrant, upon subsequent exercise of this Warrant the Holder shall have the right to receive the same kind and number of shares
of common stock and other securities, cash or other property as would have been distributed to the Holder upon such reorganization, reclassification, consolidation or merger had the Holder exercised this Warrant immediately prior to such
reorganization, reclassification, consolidation or merger, appropriately adjusted for any subsequent event described in this Section 5. The Holder shall pay upon such exercise the Exercise Price that otherwise would have been payable pursuant
to the terms of this Warrant. If any such reorganization, reclassification, consolidation or merger results in a cash distribution in excess of the then applicable Exercise Price, the holder may, at the Holder’s option, exercise this Warrant
without making payment of the Exercise Price, and in such case the Company shall, upon distribution to the Holder, consider the Exercise Price to have been paid in full, and in making settlement to the Holder, shall deduct an amount equal to the
Exercise Price from the amount payable to the Holder. In the event of any such reorganization, merger or consolidation, the corporation formed by such consolidation or merger or the corporation which shall have acquired the assets of the Company
shall execute and deliver a supplement hereto to the foregoing effect, which supplement shall also provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Warrant. 

5.3 If the Company shall, at any time before the expiration of this Warrant, dissolve, liquidate or wind up its affairs, the Holder shall have
the right to receive upon exercise of this Warrant, in lieu of the shares of Common Stock of the Company that the Holder otherwise would have been entitled to receive, the same kind and amount of assets as would have been issued, distributed or paid
to the Holder upon any such dissolution, liquidation or winding up with respect to such Common Stock receivable upon exercise of this Warrant on the date for determining those entitled to receive any such distribution. If any such dissolution,
liquidation or winding up results in any cash distribution in excess of the Exercise Price provided by this Warrant, the Holder may, at the Holder’s option, exercise this Warrant without making payment of the Exercise Price and, in such case,
the Company shall, upon distribution to the Holder, consider the Exercise Price to have been paid in full and, in making settlement to the Holder, shall deduct an amount equal to the Exercise Price from the amount payable to the Holder. 

6. Notices to Holder. So long as this Warrant shall be outstanding (a) if the Company shall pay any dividends or make any
distribution upon the Common Stock otherwise than in cash or (b) if the Company shall offer generally to the holders of Common Stock the right to subscribe to or purchase any shares of any class of Common Stock or securities convertible into
Common Stock or any similar rights or (c) if there shall be any capital reorganization of the Company in which the Company is not the surviving entity, recapitalization of the capital stock of the Company, consolidation or merger of the Company
with or into another corporation, sale, lease or other transfer of all or substantially all of the property and assets of the Company, or voluntary or involuntary dissolution, liquidation or winding up of the Company, then in such event, the Company
shall cause to be mailed to the Holder, at least thirty (30) days prior to the relevant date described below (or such shorter period as is reasonably possible if thirty (30) days is not reasonably possible), a notice containing a
description of the proposed action and stating the date or expected date on which a record of the Company’s shareholders is to be taken for the purpose of any such dividend, distribution of 

  
 4 








 
rights, or such reclassification, reorganization, consolidation, merger, conveyance, lease or transfer, dissolution, liquidation or winding up is to take place and the date or expected date, if
any is to be fixed, as of which the holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such event. 

7. Transfer, Exercise, Exchange, Assignment or Loss of Warrant, Warrant Shares or Other Securities. 

7.1 This Warrant may be transferred, exercised, exchanged or assigned (“transferred”), in whole or in part, subject to the following
restrictions. This Warrant and the Warrant Shares or any other securities (“Other Securities”) received upon exercise of this Warrant shall be subject to restrictions on transferability until registered under the Securities Act of 1933, as
amended (the “Securities Act”), unless an exemption from registration is available. Until this Warrant and the Warrant Shares or Other Securities are so registered, this Warrant and any certificate for Warrant Shares or Other Securities
issued or issuable upon exercise of this Warrant shall contain a legend on the face thereof, in form and substance satisfactory to counsel for the Company, stating that this Warrant the Warrant Shares or Other Securities may not be sold, transferred
or otherwise disposed of unless, in the opinion of counsel satisfactory to the Company, which may be counsel to the Company, that this Warrant, the Warrant Shares or Other Securities may be transferred without such registration. This Warrant and the
Warrant Shares or Other Securities may also be subject to restrictions on transferability under applicable state securities or blue sky laws. Until this Warrant and the Warrant Shares or Other Securities are registered under the Securities Act, the
Holder shall reimburse the Company for its expenses, including attorneys’ fees, incurred in connection with any transfer or assignment, in whole or in part, of this Warrant or any Warrant Shares or Other Securities. 

7.2 Until this Warrant, the Warrant Shares or other Securities are registered under the Securities Act, the Company may require, as a
condition of transfer of this Warrant, the Warrant Shares, or Other Securities, that the transferee (who may be the Holder in the case of an exercise or exchange) represent that the securities being transferred are being acquired for investment
purposes and for the transferee’s own account and not with a view to or for sale in connection with any distribution of the security. 

7.3 Any transfer permitted hereunder shall be made by surrender of this Warrant to the Company or to the Transfer Agent at its offices with a
duly executed request to transfer the Warrant, which shall provide adequate information to effect such transfer and shall be accompanied by funds sufficient to pay any transfer taxes applicable. Upon satisfaction of all transfer conditions, the
Company or Transfer Agent shall, without charge, execute and deliver a new Warrant in the name of the transferee named in such transfer request, and this Warrant promptly shall be cancelled. 

7.4 Upon receipt by the Company of evidence satisfactory to it of loss, theft, destruction or mutilation of this Warrant and, in the case of
loss, theft or destruction, of reasonable satisfactory indemnification, or, in the case of mutilation, upon surrender of this Warrant, the Company will execute and deliver, or instruct the Transfer Agent to execute and deliver, a new Warrant of like
tenor and date, any such lost, stolen or destroyed Warrant thereupon shall become void.
