Exhibit 4.3  


 
  WARRANT AGREEMENT    
  


        WARRANT AGREEMENT (this "Agreement"), dated as of February 14, 2002, by and between The Immune Response Corporation, a Delaware corporation (the
"Company"), and Oshkim Limited Partnership, a Delaware limited partnership (the "Warrant Holder").

        WHEREAS,
the parties have entered into that certain Note Purchase Agreement, dated as of November 9, 2001, by and between the Company and the Kevin Kimberlin
Partnership, L.P., as amended by Amendment No. 1 dated as of February 14, 2002 by and between the Company, Kevin Kimberlin Partners, L.P. and the Warrant Holder (the "Note
Purchase Agreement"); and 


        WHEREAS,
pursuant to the Note Purchase Agreement, the Warrant Holder has agreed to loan to the Company Two Million ($2,000,000) Dollars (the "Loan Amount"), subject to the issuance by
the Company of a convertible secured promissory note (the "Additional Note"), and the Company has agreed to issue to the Warrant Holder warrants (the "Warrants") to purchase 1,716,001 shares of the
Company's common stock, par value $.0025 per share (the "Common Stock"), which equals the Loan Amount divided by one hundred twelve and a half (112.5%) percent of the Exercise Price (as defined in
Section 1 hereof), subject to the terms set forth herein. 



        NOW,
THEREFORE, in consideration of the foregoing and the mutual covenants and promises contained herein, and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties agree as follows: 


1. Warrants.  


        The Company hereby grants to the Warrant Holder, subject to the terms set forth herein, the right to purchase from the Company at any time and from time to time
after the date hereof until 5:00 p.m., New York City local time, on February 14, 2012 (the "Expiration Date"), up to 1,716,001 fully paid and non-assessable shares of Common
Stock, subject to adjustment pursuant to Section 3 hereof (the "Shares"), which number of Shares equals the Loan Amount divided by one hundred twelve and a half (112.5%) percent of the Exercise
Price. Notwithstanding the foregoing, this Warrant shall only be exercisable to the extent that shares issuable on exercise of this Warrant, when aggregated with shares issuable on conversion of the
Initial Note, Initial Warrant and Additional Note, would not exceed 19.99% of the Company's outstanding shares on November 9, 2001 in order to be in compliance with NASD
Rule 4350(i)(1)(D). For purposes of this Agreement, the "Exercise Price" shall initially be $1.036, which is equal to the average of the closing bid prices of the Common Stock for the five
(5) consecutive trading days immediately preceding the date hereof, subject to the adjustments pursuant to Section 3 hereof. 


2. Exercise of Warrants.  


        2.1 Exercise.    The Warrants may be exercised by the Warrant Holder, in whole or in part, by delivering the Notice of Exercise
purchase form, attached as Exhibit A hereto, duly executed by the Warrant Holder to the Company at its principal office, or at such other office
as the Company may designate, accompanied by payment, in cash or by wire transfer or check payable to the order of the Company, of the amount obtained by multiplying the number of Shares designated in
the Notice of Exercise by the Exercise Price (the "Purchase Price"). The Purchase Price may also be paid, in whole or in part, by delivery of such purchase form and of shares of Common Stock owned by
the Warrant Holder having a Fair Market Value (as defined in Section 2.3 hereof) on the last trading day ending the day immediately preceding the Exercise Date (as defined below) equal to the
portion of the Purchase Price being paid in such shares. In addition, the Warrants may be exercised, pursuant to a cashless exercise except as set forth in Section 3.3(4) below, by providing
irrevocable instructions to the Company, through delivery of the aforesaid purchase form with an appropriate reference to this 





 




Section 2.1 to issue the number of shares of the Common Stock equal to the product of (a) the number of shares as to which the Warrants are being exercised multiplied by (b) a
fraction, the numerator of which is the Fair Market Value of a share of the Common Stock on the last business day preceding the Exercise Date less the Exercise Price therefor and the denominator of
which is such Fair Market Value.
For purposes hereof, "Exercise Date" shall mean the date on which all deliveries required to be made to the Company upon exercise of Warrants pursuant to this Section 2.1 shall have been made. 


        2.2 Issuance of Certificates.    As soon as practicable after the exercise of the Warrants (in whole or in part) in accordance
with Section 2.1 hereof, the Company, at its expense, shall cause to be issued in the name of and delivered to the Warrant Holder (i) a certificate or certificates for the number of
fully paid and non-assessable Shares to which the Warrant Holder shall be entitled upon such exercise and (if applicable) (ii) a new warrant agreement of like tenor to purchase all
of the Shares that may be purchased pursuant to the portion, if any, of the Warrants not exercised by the Warrant Holder. The Warrant Holder shall for all purposes be deemed to have become the holder
of record of such Shares on the date on which the Notice of Exercise and payment of the Purchase Price in accordance with Section 2.1 hereof were delivered and made, respectively, irrespective
of the date of delivery of such certificate or certificates, except that if the date of such delivery, notice and payment is a date when the stock transfer books of the Company are closed, such person
shall be deemed to have become the holder of record of such Shares at the close of business on the next succeeding date on which the stock transfer books are open. 


        2.3 Fair Market Value.    The "Fair Market Value" of a share of Common Stock on any day means: (a) if the principal
market for the Common Stock is The Nasdaq National Market or any other national securities exchange, the last sales price of the Common Stock on such day as reported by such exchange or market, or on
a consolidated tape reflecting transactions on such exchange or market, or (b) if the principal market for the Common Stock is not a national securities exchange or The Nasdaq National Market
and the Common Stock is quoted on the National Association of Securities Dealers Automated Quotations System, the mean between the closing bid and the closing asked prices for the Common Stock on such
day as quoted on such System, or (c) if the Common Stock is not quoted on the National Association of Securities Dealers Automated Quotations System, the mean between the highest bid and lowest
asked prices for the Common Stock on such day as reported by Pink Sheets LLC; provided, however, that if none of (a), (b) or (c) above is
applicable, or if no trades have been made or no quotes are available for such day, the Fair Market Value of the Common Stock shall be reasonably determined, in good faith, by the Board of Directors
of the Company (the "Board of Directors"). 


3. Adjustments.  


        3.1 Stock Splits, Stock Dividends and Combinations.    If the Company at any time subdivides the outstanding shares of the
Common Stock or issues a stock dividend (in Common Stock) on the outstanding shares of the Common Stock, the Exercise Price in effect immediately prior to such subdivision or the issuance of such
stock dividend shall be proportionately decreased, and the number of Shares subject hereto shall be proportionately increased, and if the Company at any time combines (by reverse stock split or
otherwise) the outstanding shares of Common Stock, the Exercise Price in effect immediately prior to such combination shall be proportionately increased, and the number of
Shares subject hereto shall be proportionately decreased, effective at the close of business on the date of such subdivision, stock dividend or combination, as the case may be. 


        3.2 Merger or Consolidation.    In the case of any consolidation of the Company with, or merger of the Company with or into
another entity (other than a consolidation or merger which does not result in any reclassification or change of the outstanding capital stock of the Company), the entity formed by 


2





 




such consolidation or merger shall execute and deliver to the Warrant Holder a supplemental warrant agreement providing that the Warrant Holder of the Warrants then outstanding or to be outstanding
shall have the right thereafter (until the expiration of such Warrants) to receive, upon exercise of such Warrants, the kind and amount of shares of capital stock and other securities and property
receivable upon such consolidation or merger by a holder of the number of Shares for which such Warrants might have been exercised immediately prior to such consolidation or merger. Such supplemental
warrant agreement shall provide for adjustments which shall be identical to the adjustments provided in Section 3.1 hereof and to the provisions of Section 10 hereof. This
Section 3.2 shall similarly apply to successive consolidations or mergers. 


        3.3
The Exercise Price shall also be subject to adjustment, to the extent such adjustment will be in compliance with NASD Rule 4350(i), as follows: 



        (1)  Special Definitions. For purposes of this Section 3.3, the following definitions shall apply: 



        (A)  "Options"
shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire Common Stock or Convertible Securities. 


        (B)  "Original
Issue Date" shall mean the date of this Agreement. 


        (C)  "Convertible
Securities" shall mean any evidence of indebtedness, shares of capital stock (other than Common Stock) or other securities convertible into or exchangeable
for Common Stock. 


        (D)  "Additional
Shares of Common Stock" shall mean all shares of Common Stock issued by the Company on or after the Original Issue Date, other than shares of Common Stock
issued at any time: 



        (i)    upon
exercise of the Warrants (including any additional warrants issued to Buyer in accordance with the terms and provisions of the Note Purchase Agreement); 


        (ii)  pursuant
to the exercise of options, warrants or other Common Stock purchase rights issued (or to be issued) to employees, officers or directors of, or consultants or
advisors to, or any strategic ally of, the Company pursuant to any stock purchase or stock option plan or other arrangement approved by the Board of Directors; 


        (iii)  pursuant
to the exercise of options, warrants or Convertible Securities outstanding as of the Original Issue Date; or 



        (iv)  in
connection with the acquisition of all or part of another entity by stock acquisition, merger, consolidation or other reorganization, or by the purchase of all or
part of the assets of such other entity (including securities issued to persons formerly employed by such other entity and subsequently hired by the Company and to any brokers or finders in connection
therewith) where the Company or its stockholders own more than fifty (50%) percent of the voting power of the acquired, surviving, combined or successor company. 





        (2)  Issuance of Options and Convertible Securities. Subject to Section 3.3(1)(D) hereof, in the event the Company at
any time or from time to time after the Original Issue Date shall issue any Options or Convertible Securities, then the number of shares of Common Stock actually issued upon the exercise of such
Options or, in the case of Convertible Securities, the actual conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock. 


        (3)  Adjustment of Exercise Price Upon Issuance of Additional Shares of Common Stock. In the event the Company, after the
Original Issue Date, shall issue Additional Shares of Common Stock without consideration or for a consideration per share less than the then-applicable Exercise Price, then and in such
event, such Exercise Price shall be reduced, concurrently with such issue, to a 



3





 





price (calculated to the nearest cent) determined by multiplying the then-applicable Exercise Price by a fraction, (i) the numerator of which shall be the number of shares of
Common Stock issued and outstanding (on a fully-diluted basis) immediately prior to such issuance plus the quotient obtained by dividing (x) the aggregate consideration received by the Company
for the total number of Additional Shares of Common Stock so issued by (y) the Conversion Price, and (ii) the denominator of which shall be the number of shares of Common Stock issued
and outstanding (on a fully-diluted basis) immediately prior to such issuance plus the number of Additional Shares of Common Stock so issued. Upon each such adjustment of the
then-applicable Exercise Price pursuant to the provisions of this Section 3.3(3), the number of Warrant Shares purchasable upon the exercise of each Warrant shall be adjusted to the
nearest full amount by multiplying a number equal to the Exercise Price in effect immediately prior to such adjustment by the number of Warrant Shares purchasable upon the exercise of each Warrant
immediately prior to such adjustment and dividing the product so obtained by the adjusted Exercise Price. 


        (4)  Adjustment of Exercise Price Upon Adverse Market Conditions. Notwithstanding anything to the contrary contained herein,
if at any time after the Original Issue Date, the average of the closing bid prices of the Common Stock for any ten (10) consecutive trading days (the "Ten-Day Average") shall be
less than the product obtained by multiplying (x) seventy-five (75%) percent times (y) the Exercise Price otherwise then in effect (the "Adverse Market Price"), then such
Ten-Day Average may, subject to the terms of this Section 3.3(4), become and constitute the adjusted Exercise Price (the "Adjusted Exercise Price"), and the Warrants may be
exercised, in whole or in part, by the Warrant Holder at the Adjusted Exercise Price. To exercise all or any portion of the Warrants at the Adjusted Exercise Price, the Warrant Holder shall
(i) deliver written notice (the "Adverse Market Price Notice") of such intent to the Company during such time as the Ten-Day Average shall remain equal to or below the Adverse
Market Price and (ii) provide payment by cash or wire transfer of immediately available funds in respect of such Warrants to be exercised to the Company within five (5) trading days
after delivery of the Adverse Market Price Notice. The Ten-Day Average based on the ten (10) consecutive trading days ending on the date that the Adverse Market Price Notice shall
have been delivered by the Warrant Holder shall be the Adjusted Exercise Price, unless (A) the Warrant Holder shall not deliver the applicable payment by cash or wire transfer within the five
(5) trading days following delivery of the Adverse Market Price Notice or (B) the Warrant Holder shall have provided a new Adverse Market Price Notice during such five (5) trading
days period, in which case the Adjusted Exercise Price shall be adjusted based on the Ten-Day Average preceding such new Adverse Market Price Notice. The provisions of this
Section 3.3(4) shall continue until all of the Warrants shall have been exercised. The number of Warrant Shares shall not be adjusted as a result of any adjustment of the
then-applicable Exercise Price pursuant to the provisions of this Section 3.3(4). 


        (5)  Determination of Consideration. For purposes of this Section 3, the consideration received by the Company for the
issue of any Additional Shares of Common Stock shall be computed as follows: 



        (A)  Cash and Property. Such consideration shall: 



        (i)    insofar
as it consists of cash, be computed at the net amount of cash received by the Company excluding expenses, discounts and commissions payable by the Company in
connection with such issuance or sale and amounts paid or payable for accrued interest. 


        (ii)  insofar
as it consists of property other than cash, be computed at the fair value thereof at the time of such issue, as reasonably determined in good faith by the Board
of Directors net of expenses as set forth in clause (i) above; and 



        (iii)  in
the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Company for consideration that covers both 





4





 







cash and property other than cash, the proportion of such consideration so received, computed as provided in clauses (i) and (ii) above, shall be as reasonably determined in good faith
by the Board of Directors. 




        (B)  Options and Convertible Securities. The consideration per share received by the Company for Additional Shares of Common
Stock issued pursuant to Section 3.3(2), relating to Options and Convertible Securities, shall be determined by dividing: 



        (i)    the
total amount, if any, received by the Company as consideration for the issuance of such Options or Convertible Securities, plus the aggregate amount of additional
consideration paid to the Company upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of
such Options for Convertible Securities and the conversion or exchange of such Convertible Securities (subject to any adjustments in the exercise price thereof), by 


        (ii)  the
number of shares of Common Stock issued upon the exercise of such Options or the conversion or exchange of such Convertible Securities or, in the case of Options
for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities. 





        (6)  Carryover. Notwithstanding the provisions of Subsections 3.3(1) through 3.3(5), any adjustments to the Exercise Price
which would have been made but for the absence of any required shareholder approval of the issuance of the Notes and Warrants for purposes of NASD Rule 4350(i), shall be carried forward and,
immediately upon receipt of the required shareholder approval of the issuance of the Notes and Warrants for purposes of NASD Rule 4350(i), shall be made at such time. 




        3.4 Certificate as to Adjustments.    Upon the occurrence of each adjustment or readjustment of the Exercise Price pursuant to
this Section 3, the Company, at its expense, shall promptly compute such adjustment or readjustment of the Exercise Price in accordance with the terms hereof and furnish to each Holder of
Warrants a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based, including a statement of (i) the
consideration received or deemed to be received by the Company for any Additional Shares of Common Stock issued or deemed to have been issued, (ii) the Exercise Price in effect immediately
prior to such adjustment or readjustment, (iii) the number of Additional Shares of Common Stock issued or deemed to have been issued and (iv) the number of shares of Common Stock and the
amount, if any, of other securities or property that at the time would be received upon the exercise of the Warrants. The Company shall, upon the written request at any time of any Holder of Warrants,
furnish or cause to be furnished to such Holder a like certificate setting forth (x) all adjustments and readjustments of the Exercise Price since the Original Issue Date and (y) the
Exercise Price then in effect. 


        3.5 Assurances With Respect to Exercise Rights.    The Company shall not, by amendment of its Certificate of Incorporation or
By-laws 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 to be observed or performed hereunder by the Company, but shall at all times, in good faith, assist in the carrying out of all the provisions of this
Agreement and in taking of all such actions as may be necessary or appropriate in order to protect the exercise rights of the Warrant Holder against impairment or dilution. 


4. Transfers.  


        4.1 Unregistered Securities.    The Warrant Holder hereby acknowledges and agrees that the Warrants and the Shares have not been
registered under the Securities Act of 1933, as amended (the 


5





 


"Securities Act"), and are "restricted securities" under the Securities Act inasmuch as they are being acquired in a transaction not involving a public offering, and the Warrant Holder agrees not to
sell, pledge, distribute, offer for sale, transfer or otherwise dispose of the Warrants or any Shares issued upon exercise of the Warrants in the absence of (a) an effective registration
statement under the Act as to the Warrants or such Shares and registration and/or qualification of the Warrants or such Shares under any applicable Federal or state securities law then in effect or
(b) an opinion of counsel, reasonably satisfactory to the Company, that such registration and qualification are not required. 



        4.2 Transferability.    Subject to the provisions of Section 4.1 hereof, the rights under this Agreement are freely
transferable, in whole or in part, by the Warrant Holder, and such transferee shall have the same rights hereunder as the Warrant Holder. 


        4.3 Warrant Register.    The Company will maintain a register containing the names and addresses of the Warrant Holders of the
Warrants. Until any transfer of Warrants in accordance with this Agreement is reflected in the warrant register, the Company may treat the Warrant Holder as the absolute owner hereof for all purposes.
Any Warrant Holder may change such Warrant Holder's address as shown on the warrant register by written notice to the Company requesting such change. 


5. No Fractional Shares.  


        Any adjustment in the number of Shares purchasable hereunder shall be rounded to the nearest whole share. 


6. Investment Representations.  


        The Warrant Holder agrees and acknowledges that it is acquiring the Warrants and will be acquiring the Shares for its own account and not with a view to any
resale or distribution other than in accordance with Federal and state securities laws. The Warrant Holder is an "accredited investor" within the meaning of Rule 501(a) of Regulation D
promulgated under the Securities Act. 


7. Covenants as to the Shares.  


        The Company covenants and agrees that, subject to Section 6.2(c) of the Note Purchase Agreement, the shares of Common Stock issuable upon exercise of the
Warrants, will, upon issuance in accordance with the terms hereof, be duly and validly issued and outstanding, fully paid and nonassessable, with no personal liability attaching to the ownership
thereof, and free from all taxes, liens and charges with respect to the issuance thereof imposed by or through the Company; provided, however, 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 certificates in respect of such shares in a name other than
that of the Warrant Holder and the Company shall not be required to issue or deliver such certificates unless or until the person(s) requesting the issuance thereof shall have paid to the Company the
amount of such tax or it shall be established to the satisfaction of the Company that such tax has been paid. The Company further covenants and agrees that the Company will at all times have
authorized and reserved, free from preemptive rights imposed by or through the Company, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented under this
Agreement. 


8. Legend.  


        Any certificate evidencing the Shares issuable upon exercise hereof will bear a legend indicating that such securities have not been registered under the
Securities Act or under any state securities laws and may not be sold or offered for sale in the absence of an effective registration statement as to the securities under the Securities Act and any
applicable state securities law or an opinion of counsel reasonably satisfactory to the Company that such registration is not required. 


6





 



9. Rights Applicable to the Warrant Shares.  


        The parties hereby acknowledge and agree that the Shares, when issued in accordance with the terms hereof, shall be entitled to all of the same rights and
privileges provided to the Company's capital stock issued upon conversion of the Additional Note, as set forth in the Note Purchase Agreement. 



10. Dividends and Other Distributions.  


        In the event that the Company shall, at any time prior to the exercise of all Warrants, declare a dividend (other than a dividend consisting solely of shares of
Common Stock) or otherwise distribute to its stockholders any assets, properties, rights, evidence of indebtedness, securities (other than shares of Common Stock), whether issued by the Company or by
another, or any other thing of value, the Warrant Holder shall thereafter be entitled, in addition to the shares of Common Stock or other securities and property receivable upon the exercise thereof,
to receive, upon the exercise of such Warrants, the same property, assets, rights, evidences of indebtedness, securities or any other thing of value that the Warrant Holder would have been entitled to
receive at the time of such dividend or distribution as if the Warrants had been exercised immediately prior to such dividend or distribution. At the time of any such dividend or distribution, the
Company shall make (and maintain) appropriate reserves to ensure the timely performance of the provisions of this Section 10. 


11. Miscellaneous.  


        11.1 Waivers and Amendments.    This Agreement or any provisions hereof may be changed, waived, discharged or terminated only by
a statement in writing signed by the Company and by the Warrant Holder. 


        11.2 Governing Law.    This Agreement shall be governed by and construed and enforced in accordance with the internal laws of
the State of New York. 


        11.3 Notices.    All notices and other communications hereunder shall be in writing and shall be deemed to have been given when
delivered by hand or by facsimile transmission, when telexed, or upon receipt when mailed by registered or certified mail (return receipt requested), postage prepaid, to the parties at the following

provision of this Agreement, in the absence of affirmative action by the Warrant Holder to purchase the Shares, and no mere enumeration herein of the rights or privileges of the Warrant Holder, shall
give rise to any liability of such Holder for the Exercise Price or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

EXHIBIT A NOTICE OF EXERCISE
