Company Counsel does not represent any of the Purchasers and only represents the Company.

It is expressly understood and agreed that each provision contained in this Agreement and in each other Transaction Document is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and among the Purchasers.

In addition, each and every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement.

5.17          WAIVER OF JURY TRIAL . IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.

Section 4 .           Conversion .

a)        Voluntary Conversion . At any time after the Original Issue Date until this Note is no longer outstanding, the unpaid principal and then accrued and unpaid interest on this Note shall be convertible, in whole or in part, into shares of Common Stock at the option of the Holder, at any time and from time to time; provided, however, that the amount of this Note that is converted shall be no less than $25,000 and the balance on this Note following a conversion shall not be less than $25,000. The Holder shall effect conversions by delivering to the Company a Notice of Conversion, the form of which is attached hereto as Annex A (each, a “ Notice of Conversion ”), specifying therein the amount of this Note to be converted and the date on which such conversion shall be effected (such date, the “ Conversion Date ”). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is deemed delivered hereunder. No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion form be required. To effect conversions hereunder, the Holder shall not be required to physically surrender this Note to the Company unless the entire principal amount of this Note, plus all accrued and unpaid interest thereon, has been so converted in which case the Holder shall surrender this Note as promptly as is reasonably practicable after such conversion without delaying the Company’s obligation to deliver the shares on the Share Delivery Date. Conversions hereunder shall have the effect of first reducing the outstanding principal amount of this Note in an amount equal to the applicable conversion and thereafter reducing any accrued and unpaid interest. The Holder and the Company shall maintain records showing the amount(s) converted and the date of such conversion(s). The Company may deliver an objection to any Notice of Conversion within one (1) Business Day of delivery of such Notice of Conversion. In the event of any dispute or discrepancy, the records of the Company shall be controlling and determinative in the absence of manifest error. The Holder, and any assignee by acceptance of this Note, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and unconverted principal amount of this Note may be less than the amount stated on the face hereof.

b)        Conversion Price . The conversion price in effect on any Conversion Date shall be equal to twenty cents ($0.20), subject to adjustment as provided for herein (the “ Conversion Price ”).

c)        Mechanics of Conversion .

i.             Conversion Shares Issuable Upon Conversion . The number of Conversion Shares issuable upon a conversion hereunder shall be determined by the quotient obtained by dividing (x) the amount of this Note to be converted by (y) the Conversion Price.

ii.          Delivery of Conversion Shares Upon Conversion . Not later than five (5) Trading Days after each Conversion Date (the “ Share Delivery Date ”), the Company shall deliver, or cause to be delivered, to the Holder the Conversion Shares which, on or after the six month anniversary of the Original Issue Date shall be free of restrictive legends and trading restrictions (other than those which may then be required by the Purchase Agreement) representing the number of Conversion Shares being acquired upon the conversion of this Note.

iii.          Reservation of Shares Issuable Upon Conversion . The Company covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of this Note, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holder (and the other holders of the Notes), not less than such aggregate number of shares of the Common Stock as shall (subject to the terms and conditions set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section 5) upon the conversion of the then outstanding principal amount and accrued and unpaid interest of this Note. The Company covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable.

iv.          Fractional Shares . No fractional shares or scrip representing fractional shares shall be issued upon the conversion of this Note. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such conversion, the Company shall at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Conversion Price or round up to the next whole share.

v.            Transfer Taxes and Expenses . The issuance of Conversion Shares on conversion of this Note shall be made without charge to the Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such Conversion Shares, provided that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such Conversion Shares upon conversion in a name other than that of the Holder of this Note so converted and the Company shall not be required to issue or deliver such Conversion Shares unless or until the Person or Persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice of Conversion and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Conversion Shares.

d)        Mandatory Conversion . This Note (including all outstanding principal and accrued and unpaid interest hereon), shall automatically convert into shares of Common Stock, as provided for herein, on the Mandatory Conversion Date. The Company shall promptly notify the Holders, in writing, of the occurrence of the Mandatory Conversion Date. The provisions of Section 3(c) shall apply to such conversion. On and after the Mandatory Conversion Date, this Note shall be deemed fully paid and the Holder shall be deemed to be the record owner of the number of shares to Common Stock into which this Note has been converted.

Section 5 .           Certain Adjustments .

a)        Stock Dividends and Stock Splits . If the Company, at any time while this Note is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any Common Stock Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon conversion of, or payment of interest on, the Notes), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the Company, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event, and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

b)        Subsequent Equity Sales . If, at any time while this Note is outstanding, the Company sells or grants any option to purchase or sells or grants any right to reprice, or otherwise disposes of or issues, any Common Stock or Common Stock Equivalents entitling any Person to acquire shares of Common Stock at an effective price per share that is lower than the then Conversion Price (such lower price, the “ Base Conversion Price ” and such issuances, collectively, a “ Dilutive Issuance ”) (if the holder of the Common Stock or Common Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share that is lower than the Conversion Price, such issuance shall be deemed to have occurred for less than the Conversion Price on such date of the Dilutive Issuance), then the Conversion Price shall be reduced to equal the Base Conversion Price. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued. Notwithstanding the foregoing, no adjustment will be made under this Section 5(b) in respect of an Exempt Issuance. The Company shall notify the Holder in writing, no later than the Trading Day following the issuance of any Common Stock or Common Stock Equivalents subject to this Section 5(b), indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice, the “ Dilutive Issuance Notice ”). For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 5(b), upon the occurrence of any Dilutive Issuance, the Holder is entitled to receive a number of Conversion Shares based upon the Base Conversion Price on or after the date of such Dilutive Issuance, regardless of whether the Holder accurately refers to the Base Conversion Price in the Notice of Conversion. Notwithstanding anything to the contrary that may be contained herein, the provisions of this Section 5(b) shall be of no further force and effect with respect to any Dilutive Issuance that occurs subsequent to an Equity Raise Event, if any.

c)        Fundamental Transaction . If, at any time while this Note is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “ Fundamental Transaction ”), then, upon any subsequent conversion of this Note, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “ Alternate Consideration ”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Note is convertible immediately prior to such Fundamental Transaction. For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one (1) share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Note following such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “ Successor Entity ”) to assume in writing all of the obligations of the Company under this Note and the other Transaction Documents (as defined in the Purchase Agreement) in accordance with the provisions of this Section 5(d) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the holder of this Note, deliver to the Holder in exchange for this Note a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Note which is convertible for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon conversion of this Note (without regard to any limitations on the conversion of this Note) prior to such Fundamental Transaction, and with a conversion price which applies the conversion price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such conversion price being for the purpose of protecting the economic value of this Note immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Note and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein.

d)        Calculations . All calculations under this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be.

e)        Notice to the Holder .

ii.          Notice to Allow Conversion by Holder . If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered to the Holder at its last address as it shall appear upon the Note Register, at least twenty (20) calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice.

Section 6 .           Redemption; Prepayment .

a)        Optional Redemption at Election of the Holder . Within five (5) Business Days following the consummation of an Equity Raise Event, the Company shall deliver a notice to the Holder stating that an Equity Raise Event has occurred (the “ ER Notice ”). Within ten (10) Business Days of receipt of the ER Notice, the Holder may deliver to the Company the written notice (a “ Redemption Notice ”) of its irrevocable election to have all (but not less than all) of the then outstanding principal and accrued and unpaid interest of this Note redeemed (a “ Redemption ”) for cash on the fifth (5 ^th ) Business Day following the date of the Redemption Notice (such date, the “ Redemption Date ”).

b)        Redemption Procedure . The payment of cash pursuant to a Redemption shall be payable on the Redemption Date upon delivery of this Note to the Company for cancelation.

c)        Optional Prepayment . Notwithstanding anything to the contrary contained herein, so long as no Event of Default shall have occurred and be continuing, then at any time after the Company Prepayment Date, the Company shall have the right, exercisable on not less than twenty (20) days prior written notice to the Holders of all then outstanding Notes, to prepay all of the outstanding Notes in accordance with this Section 6(c). Any notice of prepayment hereunder (an “ Optional Prepayment Notice ”) shall be delivered to the Holders of such Notes at their registered addresses appearing on the books and records of the Company and shall state that the Company is exercising its right to prepay all of the Notes on the date that is the twenty-first day following the giving of the Optional Prepayment Notice (the “ Optional Prepayment Date ”).

The failure of the Company or the Holder to insist upon strict adherence to any term of this Note on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Note on any other occasion. Any waiver by the Company or the Holder must be in writing.

f)          Severability . If any provision of this Note is invalid, illegal or unenforceable, the balance of this Note shall remain in effect, and if any provision is inapplicable to any Person or circumstance, it shall nevertheless remain applicable to all other Persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates the applicable law governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum rate of interest permitted under applicable law. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or interest on this Note as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Note, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Holder, but will suffer and permit the execution of every such as though no such law has been enacted.

g)        Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief .  The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note and any of the other Transaction Documents at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Note.  The Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any such breach or any such threatened breach, without the necessity of showing economic loss and without any bond or other security being required. The Company shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the terms and conditions of this Note.

h)        Next Business Day . Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.

i)          Headings . The headings contained herein are for convenience only, do not constitute a part of this Note and shall not be deemed to limit or affect any of the provisions hereof.

Re: Agreement to Exchange Outstanding Debt

Gentlemen:

This will confirm the agreement we have reached with respect to the outstanding debt due and owing from Protalex, Inc. (“Protalex”) to Niobe Ventures, LLC (“Niobe”) as evidenced by promissory notes issued by Protalex to Niobe (the “Notes”).

As we have advised you, Protalex is contemplating a private placement of a minimum of $1 million and a maximum of $2 million of Senior Convertible 10% Notes, due on the fifth anniversary date of issuance (the “Private Placement”). Simultaneous with the initial closing of the Private Placement, the Company and Niobe hereby unconditionally agree to exchange the full principal amount of the Notes for shares of Protalex common stock, par value $.00001 per share (“Common Stock”), at the price per share of $1.20. Upon such exchange, the outstanding indebtedness represented by the Notes and all of the rights, duties and obligations of all parties to the credit facility agreements relating to the Notes, the Notes and the related security agreements shall immediately terminate, other than Niobe’s right to the payment in cash of accrued and unpaid interest under the Notes which will be evidenced by a new note with a due date after the maturity date of the notes issued in the Private Placement.

Niobe agrees and acknowledges that the shares of Common Stock to be issued to Niobe upon conversion of the Notes as contemplated by this letter agreement (the “Shares”) will be “restricted securities” and that the Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any applicable state securities law and that it is acquiring the Shares as principal for its own account and not with a view to or for distributing or reselling such Shares or any part thereof in violation of the Securities Act or any applicable state securities law, has no present intention of distributing any of such Shares in violation of the Securities Act or any applicable state securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Shares in violation of the Securities Act or any applicable state securities law (this representation and warranty not limiting such Purchaser’s right to sell the Shares otherwise in compliance with applicable federal and state securities laws).

Upon issuance of the Shares as contemplated by this letter agreement, the Shares shall be duly authorized, full paid and nonassessable shares of Common Stock.

In furtherance of the transactions contemplated by this letter agreement, each of Protalex and Niobe, at any time or from time to time after the date hereof, agree to cooperate with each other, and at the request of the other party, to execute and deliver any further instruments or documents and to take all such further action as the other party may reasonably request in order to evidence or effectuate the consummation of the transactions contemplated hereby and to otherwise carry out the intent of the parties hereto.

In the event that the Private Placement is not consummated on or before March 31, 2018, then this letter agreement and the rights and obligations hereunder shall be null and void, ab initio.
