WARRANT

Warrant No.
Dated: December 24, 2007

REXAHN PHARMACEUTICALS, INC., a Delaware corporation (the “Company”), hereby certifies that, for value received, Kim Kyung Mi or its registered assigns (the “Holder”), is entitled to purchase from the Company up to a total of   shares of the common stock, US$0.0001 par value per share (the “Common Stock”), of the Company (each such share, a “Warrant Share” and all such shares, the “Warrant Shares”) at an exercise price equal to US$1.80 per share (as adjusted from time to time as provided in Section 9, the “Exercise Price”), at any time and from time to time from and after the date hereof and through and including the date that is three years from the date of issuance hereof (the “Expiration Date”, as adjusted pursuant to Section 4(a)), and subject to the following terms and conditions.  This warrant (this “Warrant”) is issued pursuant to that certain Securities Purchase Agreement, dated as of December 17, 2007, by and between the Company and _______________ (the “Purchase Agreement”).
 

 
1.           Definitions.  In addition to the terms defined elsewhere in this Warrant, capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement.  As used herein, the term “Closing Price” means, as of any date, the closing price of the Common Stock as reported on the primary Eligible Market for such date.

2.           Registration of Warrant.  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.

3.           Registration of Transfers.  The Company shall register the transfer of any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment attached hereto on Annex B duly completed and signed, to the Transfer Agent or to the Company at its address specified herein.  Upon any such registration or transfer, a new warrant to purchase Common Stock, in substantially the form of this Warrant (any such new warrant, a “New Warrant”), evidencing the portion of this Warrant so transferred shall be issued to the transferee and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder.  The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a holder of a Warrant.

4.           Exercise and Duration of Warrant.

a)           This Warrant shall be exercisable by the registered Holder at any time and from time to time on or after the date hereof to and including the Expiration Date.  At 18:30 (New York City time) on the Expiration Date, the portion of this Warrant not exercised prior thereto shall be and become void and of no value; provided that, if the average of the Closing Prices for the five Trading Days immediately prior to (but not including) the Expiration Date exceeds the Exercise Price on the Expiration Date, then this Warrant shall be deemed to have been exercised in full (to the extent not previously exercised) on a “cashless exercise” basis at 18:30 (New York City time) on the Expiration Date if a “cashless exercise” may occur at such time pursuant to Section 10 below.  Notwithstanding anything to the contrary herein, the Expiration Date shall be extended for each day following the Effective Date of the initial Registration Statement that such Registration Statement is not effective.

b)           A Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in the form attached hereto on Annex A (the “Exercise Notice”), appropriately completed and duly signed, including the certification contained therein to the effect that the Holder is not a U.S. Person, (ii) a written opinion of counsel to the effect that the Warrant and the securities delivered upon exercise thereof have been registered under the 1933 Act or are exempt from registration thereunder, and (iii) payment of the Exercise Price for the number of Warrant Shares as to which this Warrant is being exercised (which may take the form of a “cashless exercise” if so indicated in the Exercise Notice and if a “cashless exercise” may occur at such time pursuant to Section 10 below), and the date such items are delivered to the Company (as determined in accordance with the notice provisions hereof) is an “Exercise Date.”  The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder.  Execution and delivery of the Exercise Notice shall have the same effect as cancellation of the original Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant Shares.
 
2

 
c)           Notwithstanding any provision hereof to the contrary, this Warrant may not be exercised within the United States, and the Warrant Shares may not be delivered within the United States upon exercise, other than in offerings deemed to meet the definition of “offshore transaction” pursuant to Rule 902(h) under the 1933 Act, unless registered under the Securities Act or an exemption from such registration is available.

5.           Delivery of Warrant Shares.

a)           Upon exercise of this Warrant, the Company shall promptly (but in no event later than three Trading Days after the Exercise Date) issue or cause to be issued and cause to be delivered to or upon the written order of the Holder and in such name or names as the Holder may designate, a certificate for the Warrant Shares issuable upon such exercise, free of restrictive legends unless a registration statement covering the resale of the Warrant Shares and naming the Holder as a selling stockholder thereunder is not then effective and the Warrant Shares are not freely transferable without volume restrictions pursuant to Rule 144 under the 1933 Act.  The Holder, or any Person so designated by the Holder to receive Warrant Shares, shall be deemed to have become holder of record of such Warrant Shares as of the Exercise Date.  The Company shall, upon request of the Holder and provided a registration statement under the Securities Act providing for the resale of the Warrant Shares is then in effect, use its reasonable best efforts to deliver Warrant Shares hereunder electronically through the Depository Trust Corporation or another established clearing corporation performing similar functions.

b)           This Warrant is exercisable, either in its entirety or, from time to time, for a portion of the number of Warrant Shares.  Upon surrender of this Warrant following one or more partial exercises, the Company shall issue or cause to be issued, at its expense, a New Warrant evidencing the right to purchase the remaining number of Warrant Shares.

c)           The Company’s obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares.  Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock upon exercise of the Warrant  as required pursuant to the terms hereof.
 
3

 
6.           Charges, Taxes and Expenses.   Issuance and delivery of certificates for shares of Common Stock upon exercise of this Warrant shall be made without charge to the Holder for any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company; 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 registration of any certificates for Warrant Shares or a Warrant in a name other than that of the Holder or an Affiliate thereof.  The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

7.           Replacement of Warrant.  If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested.  Applicants for a New Warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Company may prescribe.

8.           Reservation of Warrant Shares.  The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, the number of Warrant Shares which are then issuable and deliverable upon the exercise of this entire Warrant, free from preemptive rights or any other contingent purchase rights of persons other than the Holder (taking into account the adjustments and restrictions of Section 9). The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable.  The Company will take all such action as may be necessary to assure that such shares of Common Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Common Stock may be listed.

9.           Certain Adjustments.  The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 9.

a)           Stock Dividends and Splits.  If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be adjusted to equal the product of (x) the existing Exercise Price multiplied by (y) 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 clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination.
 
4

 
b)           Pro Rata Distributions.  If the Company, at any time while this Warrant is outstanding, distributes to all of its holders of Common Stock (i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock covered by the preceding paragraph), (iii) rights or warrants to subscribe for or purchase any security, or (iv) any other asset (in each case, “Distributed Property”), then in each such case the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution shall be adjusted (effective on such record date) to equal the product of (x) the existing Exercise Price multiplied by (y) a fraction of which the denominator shall be the average of the Closing Prices for the 30 Trading Days immediately prior to (but not including) such record date and of which the numerator shall be such average less the then fair market value of the Distributed Property distributed in respect of one outstanding share of Common Stock, as reasonably determined by Company.

c)           Fundamental Transactions.  If at any time while this Warrant is outstanding, (i) the Company effects any merger or consolidation of the Company with or into another Person, (ii) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (iii) any tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property or (iv) the Company effects any reclassification 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 (other than as a result of a subdivision or combination of shares of Common Stock covered by Section 9(a) above) (in any such case, a “Fundamental Transaction”), then the Holder shall have the right thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant (the “Alternate Consideration”).  The aggregate Exercise Price for this Warrant will not be affected by any such Fundamental Transaction, but the Company shall apportion such aggregate Exercise 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 exercise of this Warrant following such Fundamental Transaction.  In the event of a Fundamental Transaction, the Company or the successor or purchasing Person, as the case may be, shall execute with the Holder a written agreement providing that:

(x)           this Warrant shall thereafter entitle the Holder to purchase the Alternate Consideration in accordance with this Section 9(c),
 
5

 
(y)           in the case of any such successor or purchasing Person, upon such consolidation, merger, statutory exchange, combination, sale or conveyance such successor or purchasing Person shall be jointly and severally liable with the Company for the performance of all of the Company’s obligations under this Warrant and the Purchase Agreement, and

(z)           if registration or qualification is required under the 1933 Act, the 1934 Act or applicable state law for the public resale by the Holder of shares of stock and other securities so issuable upon exercise of this Warrant, such registration or qualification shall be completed prior to such reclassification, change, consolidation, merger, statutory exchange, combination or sale.

If, in the case of any Fundamental Transaction, the Alternate Consideration includes shares of stock, other securities, other property or assets of a Person other than the Company or any such successor or purchasing Person, as the case may be, in such Fundamental Transaction, then such written agreement shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holder as the Board of Directors of the Company shall reasonably consider necessary by reason of the foregoing.  At the Holder’s request, any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new warrant consistent with the foregoing provisions and evidencing the Holder’s right to purchase the Alternate Consideration for the aggregate Exercise Price upon exercise thereof.  The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (c) and insuring that the Warrant (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.  If any Fundamental Transaction constitutes or results in a “Rule 13e-3 transaction” as defined in Rule 13e-3 under the 1934 Act with respect to the Company in which the consideration issued consists principally of cash or stock in a non-public company, then at the request of the Holder delivered before the 90th day after such Fundamental Transaction, the Company (or any such successor or surviving entity) will purchase the Warrant from the Holder for a purchase price, payable in cash within five Trading Days after such request (or, if later, on the effective date of the Fundamental Transaction), equal to the Black-Scholes value of the remaining unexercised portion of this Warrant on the date of such request.

d)           Subsequent Equity Sales.

i)           If, at any time while this Warrant is outstanding, the Company issues Additional Shares of Stock (as defined below) at an effective net price to the Company (the “Diluted Price”) that is less than the Exercise Price as adjusted hereunder to such date, then and in each such case the then-effective Exercise Price shall be reduced, as of the close of business on the date of such issue or sale, to equal the Diluted Price.

ii)           No adjustment shall be made under this Section 9(d) upon the issuance by the Company of warrants or options to purchase Common Stock or preferred stock, and any adjustment  in connection with such options or warrants shall be made at the time such options or warrants are exercised and the Company issues Common Stock or preferred stock, as applicable, to the holder thereof.
 
6

 
iii)           For purposes of this Section 9(d), “Additional Shares of Stock” shall mean all shares of Common Stock and/or preferred stock issued by the Company, other than: (1) shares of Common Stock issued upon conversion of any shares of preferred stock of the Company; (2) shares of Common Stock and/or preferred stock and/or warrants and/or options (and the Common Stock or preferred stock issued upon the exercise of such warrants and/or options), issued before or after the Closing Date to directors, officers, employees, consultants and other advisors of the Company and which are approved by at least a majority of the Board of Directors of the Company; and  (3) shares of Common Stock or preferred stock or other rights issued in connection with any stock dividends, combinations, splits, recapitalizations and the like.

e)           Number of Warrant Shares.  Simultaneously with any adjustment to the Exercise Price pursuant to paragraphs (a), (b) or (d) of this Section 9, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the increased or decreased number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment.

f)           Calculations.  All calculations under this Section 9 shall be made to the nearest cent or the nearest 1/100th of a share, as applicable.  The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

g)           Notice of Adjustments.  Upon the occurrence of each adjustment pursuant to this Section 9, the Company at its expense will promptly, but in any event no later than ten Trading Days after such occurrence compute such adjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based.  Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s Transfer Agent.

h)           Notice of Corporate Events.  If the Company (i) declares a dividend or any other distribution of cash, securities or other property in respect of its Common Stock, including without limitation any granting of rights or warrants to subscribe for or purchase any capital stock of the Company or any Subsidiary, (ii) authorizes or approves, enters into any agreement contemplating or solicits stockholder approval for any Fundamental Transaction or (iii) authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company, then the Company shall deliver to the Holder a notice describing the material terms and conditions of such transaction, at least 20 calendar days prior to the applicable record or effective date on which a Person would need to hold Common Stock in order to participate in or vote with respect to such transaction, and the Company will take all steps reasonably necessary in order to insure that the Holder is given the practical opportunity to exercise this Warrant prior to such time so as to participate in or vote with respect to such transaction; provided, however, that the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such notice.
 
7

 
10.           Payment of Exercise Price.  The Holder shall pay the Exercise Price in immediately available funds; provided, however, that if the Registration Statement did not become effective on or before the Required Effectiveness Date (as defined in the Registration Rights Agreement) and is not continuously effective through the Expiration Date, the Holder may satisfy its obligation to pay the Exercise Price through a “cashless exercise,” in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows:
 
 
X = Y [(A-B)/A]
   
where:              
 
   
 
X = the number of Warrant Shares to be issued to the Holder.
   
 
Y = the number of Warrant Shares with respect to which this Warrant is being exercised.
   
 
A = the arithmetic average of the Closing Prices for the 30 Trading Days immediately prior to (but not including) the Exercise Date.
   
 
B = the Exercise Price.
 
For purposes of Rule 144 promulgated under the 1933 Act, it is intended, understood and acknowledged that the Warrant Shares issued in a cashless exercise transaction shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued pursuant to the Purchase Agreement.

11.           Fractional Shares.  The Company shall not be required to issue or cause to be issued fractional Warrant Shares on the exercise of this Warrant.  If any fraction of a Warrant Share would, except for the provisions of this Section 11, be issuable upon exercise of this Warrant, the number of Warrant Shares to be issued will be rounded up to the nearest whole share.

12.           Notices.  Any and all notices or other communications or deliveries hereunder (including without limitation any Exercise Notice) shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section 12 prior to 18:30 (New York City time) on a Trading Day, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section 12 on a day that is not a Trading Day or later than 18:30 (New York City time) and earlier than 24:00 (New York City time) on any Trading Day, (iii) the Trading Day following the date of mailing, if sent by nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given.  The address for such notices or communications shall be as set forth in the Purchase Agreement.
 
8

 
13.           Warrant Agent.  The Company shall serve as warrant agent under this Warrant.  Upon 30 days’ notice to the Holder, the Company may appoint a new warrant agent.  Any corporation into which the Company or any new warrant agent may be merged or any corporation resulting from any consolidation to which the Company or any new warrant agent shall be a party or any corporation to which the Company or any new warrant agent transfers substantially all of its corporate trust or stockholders services business shall be a successor warrant agent under this Warrant without any further act.  Any such successor warrant agent shall promptly cause notice of its succession as warrant agent to be mailed (by first class mail, postage prepaid) to the Holder at the Holder’s last address as shown on the Warrant Register.

14.           Miscellaneous.

a)           Subject to the restrictions on transfer set forth on the first page hereof and provided that any transferee is an “accredited investor” as that term is defined in Rule 501(a)(3) of Regulation D under the Securities Act of 1933, as amended, and (i) agrees to all the terms herein and the terms in the Purchase Agreement, with respect to the Warrant and the Warrant Shares, that apply to the Purchasers, (ii) provides investment purposes representations with respect to this Warrant and the Warrant Shares comparable to Section 4 of the Purchase Agreement and (iii) at least 100,000 Warrant Shares (appropriately adjusted for any stock dividend, split or combination of Common Stock) may be acquired under the assigned Warrant, this Warrant may be assigned by the Holder.  This Warrant may not be assigned by the Company except to a successor in the event of a Fundamental Transaction.  This Warrant shall be binding on and inure to the benefit of the parties hereto and their respective successors and assigns.  Subject to the preceding sentence, nothing in this Warrant shall be construed to give to any Person other than the Company and the Holder any legal or equitable right, remedy or cause of action under this Warrant.  This Warrant may be amended only in writing signed by the Company and the Holder and their successors and assigns.

b)           The Company will not, by amendment of its governing documents or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder against impairment.  Without limiting the generality of the foregoing, the Company (i) will not increase the par value of any Warrant Shares above the amount payable therefor on such exercise, (ii) will take all such action as may be reasonably necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares on the exercise of this Warrant, and (iii) will not close its stockholder books or records in any manner which unreasonably interferes with the timely exercise of this Warrant.

c)           GOVERNING LAW; VENUE; WAIVER OF JURY TRIAL.  ALL QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY, ENFORCEMENT AND INTERPRETATION OF THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE REPUBLIC OF KOREA  WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES.  EACH PARTY HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE SEOUL CENTRAL DISTRICT COURT OF THE REPUBLIC OF KOREA, FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR WITH ANY TRANSACTION CONTEMPLATED HEREBY OR DISCUSSED HEREIN (INCLUDING WITH RESPECT TO THE ENFORCEMENT OF ANY OF THE TRANSACTION DOCUMENTS), AND HEREBY IRREVOCABLY WAIVES, AND AGREES NOT TO ASSERT IN ANY SUIT, ACTION OR PROCEEDING, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF ANY SUCH COURT, OR THAT SUCH SUIT, ACTION OR PROCEEDING IS IMPROPER.  EACH PARTY HEREBY IRREVOCABLY WAIVES PERSONAL SERVICE OF PROCESS AND CONSENTS TO PROCESS BEING SERVED IN ANY SUCH SUIT, ACTION OR PROCEEDING BY MAILING A COPY THEREOF VIA REGISTERED OR CERTIFIED MAIL OR OVERNIGHT DELIVERY (WITH EVIDENCE OF DELIVERY) TO SUCH PARTY AT THE ADDRESS IN EFFECT FOR NOTICES TO IT UNDER THIS WARRANT AND AGREES THAT SUCH SERVICE SHALL CONSTITUTE GOOD AND SUFFICIENT SERVICE OF PROCESS AND NOTICE THEREOF. NOTHING CONTAINED HEREIN SHALL BE DEEMED TO LIMIT IN ANY WAY ANY RIGHT TO SERVE PROCESS IN ANY MANNER PERMITTED BY LAW.  THE COMPANY AND THE HOLDER HEREBY WAIVE ALL RIGHTS TO A TRIAL BY JURY.

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

e)           In case any one or more of the provisions of this Warrant shall be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Warrant shall not in any way be affected or impaired thereby and the parties will attempt in good faith to agree upon a valid and enforceable provision which shall be a commercially reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Warrant.
