REFOCUS GROUP, INC.    
    
    WARRANT TO PURCHASE COMMON STOCK    
    

VOID AFTER 5:30 P.M., EASTERN STANDARD

TIME, ON THE EXPIRATION DATE  

        THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "ACT"), AND MAY NOT BE OFFERED, SOLD, PLEDGED, HYPOTHECATED, DONATED OR OTHERWISE TRANSFERRED WITHOUT COMPLIANCE WITH THE REGISTRATION OR QUALIFICATION PROVISIONS OF APPLICABLE FEDERAL,
STATE AND FOREIGN SECURITIES LAWS OR APPLICABLE EXEMPTIONS THEREFROM.

        FOR
VALUE RECEIVED, Refocus Group, Inc., a Delaware corporation (the "Company"), hereby agrees to sell upon the terms and on the conditions hereinafter set forth, but no later
than 5:30 p.m., Eastern Standard Time, on the Expiration Date (as hereinafter defined) to NBCN CLEARING INC. I/T/F Kingsdale Capital
Markets Inc. or registered assigns (the "Holder"), under the terms as hereinafter set forth, one hundred seventy thousand
(170,000) fully paid and non-assessable shares of Company common stock, par value $0.0001 per share (the "Warrant Stock"), at a purchase price per share of Two and
No/100 Dollars ($2.00) (the "Warrant Price"), pursuant to this warrant (this "Warrant"). The number of shares of Warrant Stock to be so issued and the Warrant Price are subject to adjustment in
certain events as hereinafter set forth. The term "Common Stock" shall mean, when used herein, unless the context otherwise requires, the stock and other securities and property at the time receivable
upon the exercise of this Warrant. 

        This
Warrant is being issued to Holder for services rendered by Kingsdale Capital Markets Inc. to the Company.. This Warrant shall be interpreted in a manner consistent with the
warrants issued to the purchasers of Company securities pursuant to that certain Confidential Private Placement Memorandum, dated October 21, 2003, as supplemented, modified and amended from
time to time (the "Memorandum"). Capitalized terms used and not otherwise defined herein shall have the respective meanings attributed thereto in Section 10. 

        1.    Exercise of Warrant.    

        (a)   The
Holder may exercise this Warrant according to its terms by surrendering this Warrant to the Company at the address set forth in Section 11, the subscription
form attached hereto having then been duly executed by the Holder, accompanied by cash, certified check or bank draft in payment of the purchase price, in lawful money of the United States of America,
for the number of shares of the Warrant Stock specified in the subscription form, or as otherwise provided in this Warrant prior to 5:30 p.m., Eastern Standard Time, on December 23, 2006
(the "Expiration Date"). 

        (b)   This
Warrant may be exercised in whole or in part so long as any exercise in part hereof would not involve the issuance of fractional shares of Warrant Stock. If
exercised in part, the Company shall deliver to the Holder a new Warrant, identical in form, in the name of the Holder, evidencing the right to purchase the number of shares of Warrant Stock as to
which this Warrant has not been exercised, which new Warrant shall be signed by the Chief Executive Officer, President, Secretary or the Assistant Secretary of the Company. The term "Warrant" as used
herein shall include any subsequent Warrant issued as provided herein. 

        (c)   No
fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. The Company shall pay cash in lieu of fractions with
respect to the 

 

Warrants
based upon the fair market value of such fractional shares of Common Stock (which shall be the closing price of such shares on the exchange or market on which the Common Stock is then traded
or quoted) at the time of exercise of this Warrant. 

        (d)   In
the event of any exercise of the rights represented by this Warrant, a certificate or certificates for the Warrant Stock so purchased, registered in the name of the
Holder, shall be delivered to the Holder within a reasonable time after such rights shall have been so exercised. The person or entity in whose name any certificate for the Warrant Stock is issued
upon exercise of the rights represented by this Warrant shall for all purposes be deemed to have become the holder of record of such shares immediately prior to the close of business on the date on
which the Warrant was surrendered and payment of the Warrant Price and any applicable taxes was made, irrespective of the date of delivery of such certificate, except that, if the date of such
surrender 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 such shares at the opening of business on the next
succeeding date on which the stock transfer books are open. Except as provided in Section 4 hereof, the Company shall pay any and all documentary stamp or similar issue or transfer taxes
payable in respect of the issue or delivery of shares of Common Stock on exercise of this Warrant. 

        2.    Disposition of Warrant Stock and Warrant.    

        (a)   The
Holder hereby acknowledges that this Warrant and any Warrant Stock purchased pursuant hereto are not being registered (i) under the Act on the ground that the
issuance of this Warrant is exempt from registration under Section 4(2) of the Act as not involving any public offering and (ii) under any applicable state securities law because the
issuance of this Warrant does not involve any public offering; and that the Company's reliance on the Section 4(2) exemption of the Act and under applicable state securities laws is predicated
in part on the representations hereby made to the Company by the Holder that it is acquiring this Warrant and will acquire the Warrant Stock for investment for its own account, with no present
intention of dividing its participation with others or reselling or otherwise distributing the same, subject, nevertheless, to any requirement of law that the disposition of its property shall at all
times be within its control. 

        The
Holder hereby agrees that it will not sell or transfer all or any part of this Warrant and/or Warrant Stock unless and until it shall have first given notice to the Company
describing such sale or transfer and furnished to the Company either (i) an opinion, reasonably satisfactory to counsel for the Company, of counsel (skilled in securities matters, selected by
the Holder and reasonably satisfactory to the Company) to the effect that the proposed sale or transfer may be made without registration under the Act and without registration or qualification under
any state law, or (ii) an interpretative letter from the U.S. Securities and Exchange Commission to the effect that no enforcement action will be recommended if the proposed sale or transfer is
made without registration under the Act. 

        (b)   If,
at the time of issuance of the shares issuable upon exercise of this Warrant, no registration statement is in effect with respect to such shares under applicable
provisions of the Act, the Company may at its election require that the Holder provide the Company with written reconfirmation of the Holder's investment intent and that any stock certificate
delivered to the Holder of a surrendered Warrant shall bear legends reading substantially as follows: 

        "THE
SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR REGISTERED OR QUALIFIED UNDER THE SECURITIES LAWS OF ANY
STATE, AND HAVE BEEN TAKEN FOR INVESTMENT PURPOSES ONLY AND NOT WITH A VIEW TO THE DISTRIBUTION THEREOF, AND NEITHER SUCH SHARES NOR ANY INTEREST THEREIN MAY BE SOLD, TRANSFERRED, ASSIGNED OR 

2

 

PLEDGED,
EXCEPT IF REGISTERED UNDER THE ACT AND APPLICABLE STATE BLUE SKY OR SECURITIES LAWS OR ANY EXEMPTIONS FROM SUCH REGISTRATION UNDER THE ACT OR REGISTRATION OR QUALIFICATION UNDER APPLICABLE
STATE BLUE SKY OR SECURITIES LAWS ARE APPLICABLE." 

In
addition, so long as the foregoing legend may remain on any stock certificate delivered to the Holder, the Company may maintain appropriate "stop transfer" orders with respect to such certificates
and the shares represented thereby on its books and records and with those to whom it may delegate registrar and transfer functions. 

        3.    Reservation of Shares.    The Company hereby agrees that at all times there shall be reserved for issuance upon
the exercise of this Warrant such number of shares of its Common Stock as shall be required for issuance upon exercise of this Warrant. The Company further agrees that all shares that may be issued
upon the exercise of the rights represented by this Warrant will be duly authorized and will, upon issuance and against payment of the exercise price, be validly issued, fully paid and
non-assessable, free from all taxes, liens, charges and preemptive rights with respect to the issuance thereof, other than taxes, if any, in respect of any transfer occurring
contemporaneously with such issuance and other than transfer restrictions imposed by federal and state securities laws. 

        4.    Exchange, Transfer, Assignment or Loss of Warrant.    This Warrant is exchangeable, without expense, at the
option of the Holder, upon presentation and surrender hereof to the Company or at the office of its stock transfer agent, if any, for other Warrants of different denominations, entitling the Holder or
Holders thereof to purchase in the aggregate the same number of shares of Common Stock purchasable hereunder. Upon surrender of this Warrant to the Company or at the office of its stock transfer
agent, if any, with the Assignment Form annexed hereto duly executed and funds sufficient to pay any transfer tax, the Company shall, without charge, execute and deliver a new Warrant in the name of
the assignee named in such instrument of assignment and this Warrant shall promptly be canceled. This Warrant may be divided or combined with other Warrants that carry the same rights upon
presentation hereof at the office of the Company or at the office of its stock transfer agent, if
any, together with a written notice specifying the names and denominations in which new Warrants are to be issued and signed by the Holder hereof. 

        5.    Capital Adjustments.    This Warrant is subject to the following further provisions: 

        (a)    Recapitalization, Reclassification and Succession.    If any recapitalization of the Company or
reclassification of its Common Stock or any merger or consolidation of the Company into or with a corporation or other business entity, or the sale or transfer of all or substantially all of the
Company's assets or of any successor corporation's assets to any other corporation or business entity (any such corporation or other business entity being included within the meaning of the term
"successor corporation") shall be effected, at any time while this Warrant remains outstanding and unexpired, then, as a condition of such recapitalization, reclassification, merger, consolidation,
sale or transfer, lawful and adequate provision shall be made whereby the Holder of this Warrant thereafter shall have the right to receive upon the exercise hereof as provided in Section 1 and
in lieu of the shares of Common Stock immediately theretofore issuable upon the exercise of this Warrant, such shares of capital stock, securities or other property as may be issued or payable with
respect to or in exchange for a number of outstanding shares of Common Stock equal to the number of shares of Common Stock immediately theretofore issuable upon the exercise of this Warrant
immediately prior to such recapitalization, reclassification, merger, consolidation, sale or transfer, and in each such case, the terms of this Warrant shall be applicable to the shares of stock or
other securities or property receivable upon the exercise of this Warrant after such consummation. 

3

 

        (b)    Subdivision or Combination of Shares.    If the Company at any time while this Warrant remains outstanding and
unexpired shall subdivide or combine its Common Stock, the number of shares of Warrant Stock purchasable upon exercise of this Warrant and the Warrant Price shall be proportionately adjusted. 

        (c)    Stock Dividends and Distributions.    If the Company at any time while this Warrant is outstanding and
unexpired shall issue or pay the holders of its Common Stock a stock dividend, then (i) the Warrant Price shall be adjusted in accordance with Section 5(d) and (ii) the number of
shares of Warrant Stock purchasable upon exercise of this Warrant shall be adjusted to the number of shares of Common Stock that Holder would have owned immediately following such action had this
Warrant been exercised immediately prior thereto. 

        If
the Company shall at any time after the date of issuance of this Warrant distribute to all holders of its Common Stock any shares of capital stock of the Company (other than Common
Stock) or evidences of its indebtedness or assets (excluding cash dividends or distributions paid from retained earnings or current year's or prior year's earnings of the Company) or rights or
warrants to subscribe for or purchase any of its securities (excluding those referred to in the immediately preceding paragraph) (any of the foregoing being hereinafter in this paragraph called the
"Securities"), then in
each such case, the Company shall reserve shares or other units of such securities for distribution to the Holder upon exercise of this Warrant so that, in addition to the shares of the Common Stock
to which such Holder is entitled, such Holder will receive upon such exercise the amount and kind of such Securities that such Holder would have received if the Holder had, immediately prior to the
record date for the distribution of the Securities, exercised this Warrant. 

        (d)    Warrant Price Adjustment.    Whenever the number of shares of Warrant Stock purchasable upon exercise of this
Warrant is adjusted, as herein provided, the Warrant Price payable upon the exercise of this Warrant shall be adjusted to that price determined by multiplying the Warrant Price immediately prior to
such adjustment by a fraction (i) the numerator of which shall be the number of shares of Warrant Stock purchasable upon exercise of this Warrant immediately prior to such adjustment, and
(ii) the denominator of which shall be the number of shares of Warrant Stock purchasable upon exercise of this Warrant immediately thereafter. 

        (e)    Certain Shares Excluded.    The number of shares of Common Stock outstanding at any given time for purposes of
the adjustments set forth in this Section 5 shall exclude any shares then directly or indirectly held in the treasury of the Company. 

        (f)    Deferral and Cumulation of De Minimis Adjustments.    The Company shall not be required to make any adjustment
pursuant to this Section 5 if the amount of such adjustment would be less than one percent (1%) of the Warrant Price in effect immediately before the event that would otherwise have given rise
to such adjustment. In such case, however, any adjustment that would otherwise have been required to be made shall be made at the time of and together with the next subsequent adjustment which,
together with any adjustment or adjustments so carried forward, shall amount to not less than one percent (1%) of the Warrant Price in effect immediately before the event giving rise to such next
subsequent adjustment. 

        (g)    Duration of Adjustment.    Following each computation or readjustment as provided in this Section 5, the
new adjusted Warrant Price and number of shares of Warrant Stock purchasable upon exercise of this Warrant shall remain in effect until a further computation or readjustment thereof is required. 

4

 

        6.    Notice to Holders.    

        (a)    Notice of Record Date.    In case: 

          (i)  the
Company shall take a record of the holders of its Common Stock (or other stock or securities at the time receivable upon the exercise of this Warrant) for the
purpose of entitling them to receive any dividend (other than a cash dividend payable out of earned surplus of the Company) or other distribution, or any right to subscribe for or purchase any shares
of stock of any class or any other securities, or to receive any other right; 

         (ii)  of
any capital reorganization of the Company, any reclassification of the capital stock of the Company, any consolidation with or merger of the Company into another
corporation, or any conveyance of all or substantially all of the assets of the Company to another corporation; or 

        (iii)  of
any voluntary dissolution, liquidation or winding-up of the Company; 

then,
and in each such case, the Company will mail or cause to be mailed to the Holder hereof at the time outstanding a notice specifying, as the case may be, (i) the date on which a record is
to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, or (ii) the date on which such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or winding-up is to take place, and the time, if any, is to be fixed, as of which the holders of record of
Common Stock (or such stock or securities at the time receivable upon the exercise of this Warrant) shall be entitled to exchange their shares of Common Stock (or such other stock or securities) for
securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, conveyance, dissolution or winding-up. Such notice shall be mailed at least
fifteen (15) days prior to the record date therein specified, or if no record date shall have been specified therein, at least thirty (30) days prior to such specified date. 

        (b)    Certificate of Adjustment.    Whenever any adjustment shall be made pursuant to Section 5 hereof, the
Company shall promptly make a certificate signed by its Chairman and Chief Executive Officer, its President or a Vice President and by its Treasurer or Assistant Treasurer or its Secretary or
Assistant Secretary, setting forth in reasonable detail the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated and the Warrant Price and
number of shares of Warrant Stock purchasable upon exercise of this Warrant after giving effect to such adjustment, and shall promptly cause copies of such certificates to be mailed (by first class
mail, postage prepaid) to the Holder of this Warrant. 

        7.    Loss, Theft, Destruction or Mutilation.    Upon receipt by the Company of evidence satisfactory to it, in the
exercise of its reasonable discretion, of the ownership and the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, of indemnity reasonably
satisfactory to the Company and, in the case of mutilation, upon surrender and cancellation thereof, the Company will execute and deliver in lieu thereof, without expense to the Holder, a new Warrant
of like tenor dated the date hereof. 

        8.    Warrant Holder Not a Stockholder.    The Holder of this Warrant, as such, shall not be entitled by reason of
this Warrant to any rights whatsoever as a stockholder of the Company. 

        9.    Registration Rights.    This Warrant and the shares of Common Stock issuable upon exercise of this Warrant will
be accorded the registration rights under the Act set forth the Engagement Letter (as defined below).

[REFOCUS
GROUP LETTERHEAD] 

December 4,
2003 

Verus
Support Services Inc.

18 East 50th Street, 10th Floor

New York, NY 10022 

Gentlemen:

        Reference
is made to that certain letter agreement, dated March 6, 2003, relating to the Verus Contingent Subscription (the "Contingent Subscription Agreement"), from Verus
Support Services Inc. ("Verus") to Refocus Group, Inc. ("Refocus"), and those certain related letter agreements, dated June 11, 2003 and August 28, 2003. Defined terms used
without definition in this letter will have the meanings set forth for such terms in the Contingent Subscription Agreement. In addition, Verus and Refocus are parties to that certain letter agreement,
dated March 6, 2003, relating to the Advisory Engagement (the "Advisory Agreement") pursuant to which Verus agreed to be appointed as a non-exclusive advisor for and on behalf of
Refocus (as successor to Presby Corp). 

        As
set forth in the Contingent Subscription Agreement, Verus agreed to provide the Verus Contingent Subscription in order to ensure that Refocus will receive at least $1.0 million
in gross proceeds in the Post-Closing Private Placement by the end of the six-month period following the date of the Contingent Subscription Agreement, which would be
September 6, 2003. In the letter agreement dated August 28, 2003, the parties amended the terms of the Contingent Subscription Agreement to extend the date on which Verus would be
required to make the Verus Contingent Subscription from September 6, 2003, to the earlier of (i) December 6, 2003, or (ii) the date upon which Refocus shall secure at least
$1.0 million in additional financing from other sources. The parties now desire to further amend the terms of the Contingent Subscription Agreement to extend the date on which Verus would be
required to make the Verus Contingent Subscription from December 6, 2003, to the earlier of (i) January 6, 2004, or (ii) the date upon which Refocus shall secure at least
$1.0 million in additional financing from other sources (such aggregate extended time period being the "Deferral Period"). 

        In
the case of clause (ii) immediately above, if the additional financing shall be on terms at least as favorable as the initial private placement that Refocus completed on
March 6, 2003, then, as set forth in the Contingent Subscription Agreement, Verus shall be released from its obligation to make the Verus Contingent Subscription. If, however, the terms of the
additional financing shall not be on terms at least as favorable as those of the March 6, 2003 private placement, then the parties agree to negotiate in good faith to determine the type and
amount of the Verus Contingent Subscription. Verus shall make such revised Verus Contingent Subscription within ten (10) days after the closing date of the additional financing. In addition, in
the event of a merger, acquisition, asset or stock purchase, or other business combination resulting in a change of control of Refocus, Verus shall be released from its obligation to make the Verus
Contingent Subscription. For purposes of this letter, a "change in control" shall be deemed to occur if any "person" or "group" (within the meaning of Section 13(d) and 14(d)(2) of the
Securities Exchange Act of 1934) becomes the ultimate "beneficial owner" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934) of more than a majority of the total
voting power of common stock of Refocus. Nothing in this letter agreement shall be deemed to be a release of Verus' obligation to make the Verus Contingent Subscription, except as stated herein or as
otherwise agreed to in writing. 

        Pending
the performance by Verus of the Verus Contingent Subscription, or the satisfaction of such obligation as a result of a closing of the Post-Closing Private Placement,
and as compensation for the further deferral of the Verus Contingent Subscription obligation, the parties hereby agree that the monthly fee otherwise due under the Advisory Agreement for the month of
December 2003 shall be waived. The Advisory Agreement and all other terms and conditions of such agreement shall remain valid and effective for all other purposes during the Deferral Period.
Such monthly fee payment obligation shall commence again beginning the earlier of (i) January 6, 2004, or (ii) the first full 

calendar
month following the month in which Verus makes the Verus Contingent Subscription or such obligation is otherwise satisfied. 

        This
letter agreement is entered into by the parties hereto without prejudice to either party's rights to assert any claim, right or remedy in respect of the validity of the original
Contingent Subscription Agreement. 

        Please
confirm your agreement to the foregoing by signing and returning to us an executed copy of this letter. 

	 	 	 	 	Very truly yours,
