EXHIBIT 10.1

THIS CONVERTIBLE PROMISSORY NOTE AND THE SECURITIES TO BE DELIVERED IN CONNECTION HEREWITH AND UPON CONVERSION HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER ANY STATE SECURITIES LAW. NO SALE, ASSIGNMENT, PLEDGE OR OTHER TRANSFER OF EITHER THIS CONVERTIBLE PROMISSORY NOTE OR ANY SUCH SECURITIES MAY BE MADE EXCEPT PURSUANT TO THE PROVISIONS OF THE ACT AND APPLICABLE STATE SECURITIES LAWS OR UNLESS AN OPINION OF COUNSEL, SATISFACTORY TO MAKER, IS OBTAINED STATING THAT SUCH SALE, ASSIGNMENT, PLEDGE OR TRANSFER IS IN COMPLIANCE WITH AN AVAILABLE EXEMPTION UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS.

THIS CONVERTIBLE PROMISSORY NOTE HAS BEEN EXECUTED AND DELIVERED OUTSIDE OF THE STATE OF FLORIDA AND NO FLORIDA DOCUMENTARY STAMP TAXES ARE DUE.

CONVERTIBLE PROMISSORY NOTE

FOR VALUE RECEIVED, CYTODYN INC., a Colorado corporation (“Maker”), hereby promises to pay to Jordan Naydenov (“Holder”) the principal amount of One Million Dollars ($1,000,000.00), together with interest thereon at a fixed simple interest rate of five percent (5%) per annum.

Principal outstanding under this Convertible Promissory Note (this “Promissory Note”) shall be due and payable in cash in a single payment on October 15, 2015 (the “Due Date”). Interest shall be payable in cash semiannually in arrears beginning on April 15, 2013, and continuing on each of October 15, 2013, April 15, 2014, October 15, 2014, April 15, 2015, and October 15, 2015, except to the extent that this Promissory Note has been previously converted into shares of Maker’s common stock (the “Shares”) as set forth below.

In connection with this Promissory Note, Holder is entitled to, at no additional cost to Holder, a warrant to purchase 1,333,333 Shares (the “Warrants,” and together with the Shares, collectively, the “Securities”) at an exercise price of $2.00 per Share (the “Exercise Price”), in substantially the form attached hereto as Exhibit A. The Warrants are exercisable at the option of the Holder at any time after October 16, 2012 (the “Effective Date”), but not later than two (2) years after the Effective Date.

All or any portion of principal and any related accrued but unpaid interest hereunder may be converted (each, a “Conversion”) at any time by Holder into a number of Shares determined by dividing the converted principal amount and related accrued but unpaid interest by the conversion price of $0.75 per Share, with the resulting number of Shares to be issued, rounded down to the nearest whole Share, being referred to as the “Conversion Share Number.”

No Conversion hereunder shall be effective unless written notice of the Conversion is given by Holder at least five (5) days prior to such Conversion, in substantially the form attached hereto as Exhibit B. Notwithstanding the foregoing, no Conversion hereunder shall be permitted after a date that is later than 30 days prior to the Due Date.

The Maker shall not issue any fractional Shares upon Conversion by Holder of any principal and related accrued but unpaid interest hereunder or upon the exercise of the Warrants. With respect to any fraction of a Share resulting from such Conversion or exercise, the Maker shall issue to Holder a number of Shares rounded down to the nearest whole Share.

Default in the payment of the principal of or interest on this Promissory Note when the same becomes due and payable shall constitute an event of default hereunder.

Upon the occurrence of an event of default, or at any time thereafter during the continuance of any such event, the Holder may, with or without notice to the Maker, declare this Promissory Note to be forthwith due and payable, whereupon this Promissory Note and the indebtedness evidenced hereby shall forthwith be due and payable, both as to principal and interest, without presentment, demand, protest, or other notice of any kind, all of which are hereby expressly waived, anything contained herein or in any other instrument executed in connection with or securing this Note to the contrary notwithstanding. If the Due Date of this Promissory Note is accelerated as provided above, the Holder may convert the principal portion of this Promissory Note into Shares at any time prior to the payment of such principal amount.

If the Maker sells all or substantially all of its assets to a third party, merges, or consolidates with another entity, or engages in any other transaction with a third party requiring approval of the shareholders of the Maker, Maker shall give prompt notice to the Holder, and Holder may immediately convert the principal amount of this Promissory Note into Shares at any time prior to the consummation of such transaction.

If this Promissory Note or any interest hereon becomes due and payable on Saturday, Sunday or other day on which commercial banks are authorized or permitted to close under the laws of the State of Oregon, the maturity of this Promissory Note or such installment shall be extended to the next succeeding business day.

Maker may elect to prepay, on or before the Due Date, but not earlier than one (1) year following the effective date of this Promissory Note, all or any portion of the outstanding principal balance under this Promissory Note, together with accrued but unpaid interest, by wire transfer or other cash equivalent acceptable to Maker; provided, however, for any such prepayment, Maker must first give Holder at least ten (10) days prior notice of such prepayment and, during such time, Holder may elect in writing to effect a Conversion of all or a portion of such principal balance, together with any accrued but unpaid interest so desired to be prepaid by Maker, into Shares as provided herein.

If the payment of principal or any payment of interest or both is more than five (5) days late, the Maker agrees to pay the Holder a late charge equal to three percent (3%) of the payment (the “Late Fee”). The provisions of this Promissory Note establishing a Late Fee shall not be deemed to extend the time for any payment due or to constitute a “grace period” giving the Maker a right to cure such default.

-2-

This Promissory Note and the Securities to be issued in connection herewith and upon Conversion hereof may not be offered, sold or otherwise disposed of except under circumstances which will not result in a violation of the Securities Act of 1933, as amended (the “Securities Act”). Upon Conversion of this Promissory Note, the Holder hereof will be required to confirm in writing, by executing the form attached as Schedule 1 to Exhibit B hereto, that the Shares so purchased are being acquired for investment and not with a view toward distribution or resale. This Promissory Note and all Shares issued upon Conversion hereof or upon the exercise of the Warrants (unless registered under the Securities Act) shall be stamped or imprinted with a legend in substantially the following form:

“THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES ACT OF ANY STATE. THE SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD, TRANSFERRED FOR VALUE, PLEDGED, HYPOTHECATED, OR OTHERWISE ENCUMBERED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION OF THEM UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES ACT OF ANY STATE OR AN APPLICABLE EXEMPTON FROM REGISTRATION UNDER SUCH ACT OR ACTS.”

With respect to any offer, sale or other disposition of this Promissory Note or any Securities to be issued in connection herewith or upon Conversion hereof prior to registration of such Promissory Note or Securities, the Holder hereof and each subsequent Holder of this Promissory Note will be required to give written notice to the Maker prior thereto, describing briefly the manner thereof, together with a written opinion of such Holder’s counsel reasonably acceptable to the Maker’s counsel, if such opinion is reasonably requested by the Maker, to the effect that such offer, sale or other disposition may be effected without registration or qualification (under the Securities Act as then in effect or any federal or state law then in effect) of this Promissory Note or such Securities and indicating whether or not under the Securities Act this Promissory Note or certificates for such Securities to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure compliance with applicable law. Promptly upon receiving such written notice and reasonably satisfactory opinion, if so requested, the Maker, as promptly as practicable, shall notify such Holder that such Holder may sell or otherwise dispose of this Promissory Note or such Securities, all in accordance with the terms of the notice delivered to the Maker. If a determination has been made pursuant to this paragraph that the opinion of counsel for the Holder is not reasonably satisfactory to the Maker, the Maker shall so notify the Holder promptly after such determination has been made and neither this Promissory Note nor any Securities shall be sold or otherwise disposed of until such disagreement has been resolved. The foregoing notwithstanding, this Promissory Note or such Securities may as to such federal laws, be offered, sold or otherwise disposed of in accordance with Rule 144 under the Securities Act, provided that the Maker shall have been furnished with such information as the Maker may

-3-

reasonably request to provide a reasonable assurance that the provisions of Rule 144 have been satisfied. This Promissory Note and each certificate representing the Securities thus transferred (except a transfer pursuant to Rule 144) shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with such laws, unless in the aforesaid opinion of counsel for the Holder, reasonably acceptable to the Maker, such legend is not required in order to ensure compliance with such laws. The Maker may issue stop transfer instructions to its transfer agent or, if acting as its own transfer agent, the Maker may stop transfer on its corporate books, in connection with such restrictions.

Any provision of this Promissory Note that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

This Promissory Note is not transferable or assignable by the Maker without the consent of the Holder. This Promissory Note is not transferable or assignable by the Holder without the consent of the Maker. If this Promissory Note is collected by law or through an attorney at law, or under advice therefrom, the Maker agrees to pay all costs of collection, including reasonable attorneys’ fees. Reasonable attorneys’ fees are defined to include, but not be limited to, all fees incurred in all matters of collection and enforcement, trial proceedings and appeals, as well as appearances in and connected with any bankruptcy proceedings or creditors’ reorganization or similar proceedings and any post judgment collection efforts.

Any failure to exercise any right, remedy or recourse hereunder shall not be deemed to be a waiver or release of the same, such waiver or release to be effected only through a written document executed by the Holder and then only to the extent specifically recited therein. A waiver or release with reference to any one event shall not be construed as continuing, as a bar to, or as a waiver or release of any subsequent right, remedy or recourse as to a subsequent event.

In no event shall the amount of interest due or payments in the nature of interest payable hereunder exceed the maximum rate of interest allowed by applicable law, as amended from time to time, and in the event any such payment is paid by the Maker or received by the Holder, then such excess sum shall be credited as a payment of principal, unless the Maker shall notify the Holder, in writing, that the Maker elects to have such excess sum returned to the Maker forthwith.

The Maker hereby waives all and every exemption secured to it by the laws and constitution of the State of Oregon, and of any other state. The Maker hereby waives demand, presentment, protest, notice of nonpayment or dishonor, and any other notice required by law and agrees that its obligation hereunder shall not be affected by any renewal or extension of the time of payment hereof, or by any indulgences.

-4-

This Promissory Note shall be governed by and construed in accordance with the laws of the State of Oregon applicable to debts and obligations incurred and to be paid solely in such jurisdiction. This Promissory Note may not be modified or amended and no provision hereof may be waived except by a written instrument executed by the parties to be bound thereby.

Warrant to Purchase

Shares of

Common Stock

As Herein Described

October 16, 2012

WARRANT TO PURCHASE COMMON STOCK OF

CYTODYN INC.

This is to certify that, for value received, Jordan Naydenov, or a proper assignee (the “Holder”), is entitled to purchase up to 1,333,333 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             , from the Company. This Warrant shall be exercisable at Two Dollars ($2.00) 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

October 15, 2014 (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 Oregon 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.

(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 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 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.
