                         VERTICAL HEALTH SOLUTIONS, INC.

                     KASHNER DAVIDSON SECURITIES CORPORATION

                                  UNDERWRITER'S

                                WARRANT AGREEMENT

                UNDERWRITER'S WARRANT AGREEMENT dated as of _________, 2002 by
and between VERTICAL HEALTH SOLUTIONS, INC. (the "Company") and KASHNER DAVIDSON
SECURITIES CORPORATION ("Underwriter" or "Kashner")

                              W I T N E S S E T H:
                              -------------------

         WHEREAS, the Company proposes to issue to the Underwriter 135,000
warrants (each an "Underwriter's Warrant") each to purchase a share of the
Company's common stock, par value $.001 per share (the "Common Stock").

         WHEREAS, the Underwriter has agreed, pursuant to the underwriting
agreement (the "Underwriting Agreement") dated ______, 2002, by and between the
Underwriter and the Company, to act as the Underwriter in connection with the
Company's proposed public offering (the "Public Offering") of 1,350,000 shares
of Common Stock (the "Offering Securities"); and

         WHEREAS, the Underwriter's Warrants to be issued pursuant to this
Agreement will be issued on the Closing Date (as such term is defined in the
Underwriting Agreement) by the Company to the Underwriter in consideration for,
and as part of, the Underwriter's compensation in connection with the
Underwriter acting as the Underwriter pursuant to the Underwriting Agreement;

         NOW, THEREFORE, in consideration of the premises, the payment by the
Underwriter to the Company of Ten Dollars ($10.00), the agreements herein set
forth and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto agree as follows:

         1. Grant. The Holder (as defined in Section 3 below) is hereby granted
            -----
the right to purchase, at any time from _________, 2003 until 5:00 p.m., New
York time, _______, 2007, up to 135,000 shares of Common Stock, at an initial
purchase price (subject to adjustment as provided in Section 8 hereof) of $9.90
per share of Common Stock (165% of the per share public offering price), subject
to the terms and conditions of this Agreement. The securities issuable, upon
exercise of the Underwriter's Warrant are sometimes referred to herein as the
"Underwriter's Securities."

         2. Warrant Certificates. The warrant certificate (the "Underwriter's
            --------------------
Warrant Certificate") to be delivered pursuant to this Agreement shall be in the
form set forth in Exhibit A attached hereto and made a part hereof, with such
appropriate insertions, omissions, substitutions, and other variations as
required or permitted by this Agreement.

<PAGE>

         3. Exercise of Underwriter's Warrant.
            ---------------------------------

            (a) The Underwriter's Warrant is exercisable during the term set
forth in Section 1 hereof payable by certified or cashier's check or money order
in lawful money of the United States. Upon surrender of Underwriters' Warrant
Certificate with the annexed Form of Election to Purchase duly executed,
together with payment of the Purchase Price (as hereinafter defined) for the
Underwriter's Securities (and such other amounts, if any, arising pursuant to
Section 4 hereof) at the Company's principal office currently located at 6925
112/th/ Circle North Suite 102, Largo, Florida 33773 the registered holder of a
Underwriter's Warrant Certificate ("Holder" or "Holders") shall be entitled to
receive a certificate or certificates for the Underwriter's Securities so
purchased. The purchase rights represented by each Underwriter's Warrant
Certificate are exercisable at the option of the Holder or Holders thereof, in
whole or in part as to Underwriter's Securities. The Underwriter's Warrant may
be exercised to purchase all or any part of the Underwriter's Securities
represented thereby. In the case of the purchase of less than all the
Underwriters' Securities purchasable on the exercise of the Underwriters'
Warrant represented by a Underwriters' Warrant Certificate, the Company shall
cancel the Underwriters' Warrant Certificate represented thereby upon the
surrender thereof and shall execute and deliver a new Underwriters' Warrant
Certificate of like tenor for the balance of the Underwriters' Securities
purchasable thereunder.

            (b) In lieu of the payment of cash upon exercise of the
Underwriters' Warrant as provided in Section 3(a), the Holder may exercise the
Underwriters' Warrant by surrendering the Underwriters' Warrant Certificate at
the principal office of the Company, accompanied by a notice stating (i) the
Holder's intent to effect such exercise by an exchange, (ii) Common Stock to be
issued upon the exchange, (iii) whether Underwriters' Warrants are to be
surrendered in connection with the exchange, and (iv) the date on which the
Holder requests that such exchange is to occur. The Purchase Price for the
Underwriters' Securities to be acquired in the exchange shall be paid by the
surrender as indicated in the notice, of Underwriters' Warrants, having a
"Value", as defined below, equal to the Purchase Price. "Value" as to each
Underwriters' Warrant shall mean the difference between the "Market Price", as
hereinafter defined, of a share of Common Stock and the then Purchase Price for
a share of Common Stock.

            By way of example of the application of the formula, assume that the
Market Price of the Common Stock is $8.00, the Purchase Price of the
Underwriters' Warrant is $6.00. On such assumptions, the Value of a
Underwriters' Warrant is $2.00 ($8.00-$6.00) and therefore for each three
Underwriters' Warrants surrendered, the Holder could acquire one share of Common
Stock in the exchange. Notwithstanding the example, the Holder shall not be
limited to exchanging Underwriters' Warrants for Common Stock.

         The Warrant Exchange shall take place on the date specified in the
notice or if the date the notice is received by the Company is later than the
date specified in the notice, on the date the notice is received by the Company.

         4. Issuance of Certificates. Upon the exercise of the Underwriters'
            ------------------------
Warrant and payment of the Purchase Price therefor, the issuance of certificates
representing the Underwriters'

                                       2

<PAGE>

Securities or other securities, properties or rights underlying such
Underwriters' Warrant, shall be made forthwith (and in any event within five (5)
business days thereafter) without further charge to the Holder thereof, and such
certificates shall (subject to the provisions of Sections 5 and 7 hereof) be
issued in the name of, or in such names as may be directed by, the Holder
thereof; 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 issuance and
delivery of any such certificates in a name other than that of the Holder, and
the Company shall not be required to issue or deliver such certificates 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 Underwriters'
Warrant Certificates and the certificates representing the Underwriters'
Securities or other securities, property or rights (if such property or rights
are represented by certificates) shall be executed on behalf of the Company by
the manual or facsimile signature of the then present Chairman or Vice Chairman
of the Board of Directors or President or Vice President of the Company,
attested to by the manual or facsimile signature of the then present Secretary
or Assistant Secretary or Treasurer or Assistant Treasurer of the Company. The
Underwriters' Warrant Certificates shall be dated the date of issuance thereof
by the Company upon initial issuance, transfer or exchange.

         5. Restriction On Transfer of Underwriters' Warrant. The Holder of
            ------------------------------------------------
an Underwriters' Warrant Certificate (and its Permitted Transferee, as defined
below), by its acceptance thereof, covenants and agrees that the Underwriters'
Warrant may be sold, transferred, assigned, hypothecated or otherwise disposed
of, in whole or in part, until _______, 2003 (one year following the effective
date of the Public Offering), only to officers and partners of the Underwriters,
or any Public Offering selling group member and their respective officers and
partners, ("Permitted Transferees"). Thereafter the Underwriters' Warrant may be
transferred, assigned, hypothecated or otherwise disposed of in compliance with
applicable law.

         6. Purchase Price.
            --------------

            (a) Initial and Adjusted Purchase Price. Except as otherwise
                -----------------------------------
provided in Section 8 hereof, the initial purchase price of the Underwriters'
Securities shall be $9.90 per share of Common Stock (165% of the per share
public offering price). The adjusted purchase price shall be the price which
shall result from time to time from any and all adjustments of the initial
purchase price in accordance with the provisions of Section 8 hereof.

                (b) Purchase Price. The term "Purchase Price" herein shall mean
                    --------------
the initial purchase price or the adjusted purchase price, depending upon the
context.

         7. Registration Rights.
            -------------------

            (a) Registration Under the Securities Act of 1933 as amended
                --------------------------------------------------------
("Act"). The Underwriters' Warrant may have not been registered under the Act.
-------
The Underwriters' Warrant Certificates may bear the following legend:

                                       3

<PAGE>

             "The securities represented by this certificate have not been
registered under the Securities Act of 1933 (the "Act"), and may not be offered
for sale or sold except pursuant to (i) an effective registration statement
under the Act, or (ii) an opinion of counsel, if such opinion and counsel shall
be reasonably satisfactory to counsel to the issuer, that an exemption from
registration under the Act is available".

                 (b) Demand Registration. (1) At any time commencing on the
                     -------------------
first anniversary of and expiring on the fifth anniversary of the effective date
of the Company's Registration Statement relating to the Public Offering (the
"Effective Date"), the Holders of a Majority (as hereinafter defined) in
interest of the Underwriters' Warrant, or the Majority in interest of the
Underwriters' Securities (assuming the exercise of all of the Underwriters'
Warrant) shall have the right, exercisable by written notice to the Company, to
have the Company prepare and file with the U.S. Securities and Exchange
Commission (the "Commission"), on one (1) occasion, a registration statement on
Form SB-2, S-1 or other appropriate form, and such other documents, including a
prospectus, as may be necessary in the opinion of both counsel for the Company
and counsel for the Holders, in order to comply with the provisions of the Act,
so as to permit a public offering and sale, of the Underwriters' Securities by
such Holders and any other Holders of the Underwriters' Warrant and/or the
Underwriters' Securities who notify the Company within fifteen (15) business
days after receipt of the notice described in Section 7(b)(2). The Holders of
the Underwriters' Warrant may demand registration prior to exercising the
Underwriters' Warrant, and may pay such exercise price from the proceeds of such
public offering.

         (2) The Company covenants and agrees to give written notice of any
registration request under this Section 7(b) by any Holders to all other
registered Holders of the Underwriters' Warrant and the Underwriters' Securities
within ten (10) calendar days from the date of the receipt of any such
registration request.

         (3) For purposes of this Agreement, the term "Majority" in reference to
the Holders of the Underwriters' Warrant or Underwriters' Securities, shall mean
in excess of fifty percent (50%) of the then outstanding Underwriters' Warrant
or Underwriters' Securities that (i) are not held by the Company, an affiliate,
officer, creditor, employee or agent thereof or any of their respective
affiliates, members of their family, persons acting as nominees or in
conjunction therewith, or (ii) have not been resold to the public pursuant to a
registration statement filed with the Commission under the Act.

             (c) Piggyback Registration. (1) If, at any time within the period
                 ----------------------
commencing on the first anniversary and expiring on the sixth anniversary of the
Effective Date, the Company should file a registration statement with the
Commission under the Act (other than in connection with a merger or other
business combination transaction or pursuant to Form S-8), it will give written
notice at least twenty (20) calendar days prior to the filing of each such
registration statement to the Underwriter and to all other Holders of the
Underwriters' Warrant and/or the Underwriters' Securities of its intention to do
so. If an Underwriter or other Holders of the Underwriters' Warrant and/or the
Underwriters' Securities notify the Company within fifteen (15) calendar days
after receipt of any such notice of its or their desire to include any
Underwriters' Securities in such proposed

                                       4

<PAGE>

registration statement, the Company shall afford the Underwriter and such
Holders of the Underwriters' Warrant and/or Underwriters' Securities the
opportunity to have any such Underwriters' Securities registered under such
registration statement. Notwithstanding the provisions of this Section 7(c)(1)
and the provisions of Section 7(d), the Company shall have the right at any time
after it shall have given written notice pursuant to this Section 7(c)(1)
(irrespective of whether a written request for inclusion of any such securities
shall have been made) to elect not to file any such proposed registration
statement, or to withdraw the same after the filing but prior to the effective
date thereof.

            (2) If the managing underwriter of an offering to which the above
piggyback rights apply, in good faith and for valid business reasons, objects to
such rights, such objection shall preclude such inclusion.

            (d) Covenants of the Company With Respect to Registration. In
                -----------------------------------------------------
connection with any registrations under Sections 7(b) and 7(c) hereof, the
Company covenants and agrees as follows:

                (1) The Company shall use its best efforts to file a
registration statement within thirty (30) calendar days of receipt of any demand
therefor pursuant to Section 7(b); provided, however, that the Company shall not
be required to produce audited or unaudited financial statements for any period
prior to the date such financial statements are required to be filed in a report
on Form 10-KSB or Form 10-QSB, as the case may be. The Company shall use its
best efforts to have any registration statement declared effective at the
earliest possible time, and shall furnish each Holder desiring to sell
Underwriters' Securities such number of prospectuses as shall reasonably be
requested.

                (2) The Company shall pay all costs (excluding fees and expenses
of Holders' counsel and any underwriting discounts or selling fees, expenses or
commissions), fees and expenses in connection with any registration statement
filed pursuant to Sections 7(b) and 7(c) hereof including, without limitation,
the Company's legal and accounting fees, printing expenses, blue sky fees and
expenses.

                (3) The Company will use its best efforts to qualify or register
the Underwriters' Securities included in a registration statement for offering
and sale under the securities or blue sky laws of such states as reasonably are
requested by the Holders, provided that the Company shall not be obligated to
execute or file any general consent to service of process or to qualify as a
foreign corporation to do business under the laws of any such jurisdiction.

                (4) The Company shall indemnify the Holders of the Underwriters'
Securities to be sold pursuant to any registration statement and each person, if
any, who controls such Holders within the meaning of Section 15 of the Act or
Section 20(a) of the Securities Exchange Act of 1934 (the "Exchange Act"),
against all loss, claim, damage, expense or liability (including all expenses
reasonably incurred in investigating, preparing or defending against any claim
whatsoever) to which any of them may become subject under the Act, the Exchange
Act or

                                       5

<PAGE>

otherwise, arising from such registration statement, but only to the same extent
and with the same effect as the provisions pursuant to which the Company has
agreed to indemnify the Underwriter contained in Section 8 of the Underwriting
Agreement.

            (5)  The Holders of the Underwriters' Securities to be sold pursuant
to a registration statement, and their successors and assigns, shall indemnify
the Company, its officers and directors and each person, if any, who controls
the Company within the meaning of Section 15 of the Act or Section 20(a) of the
Exchange Act, against all loss, claim, damage or expense or liability to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished by or on behalf of such Holders, or their successors
or assigns, for specific inclusion in such registration statement to the same
extent and with the same effect as the provisions contained in Section 8 of the
Underwriting Agreement pursuant to which the Underwriter has agreed to indemnify
the Company.

            (6)  Nothing contained in this Agreement shall be construed as
requiring the Holders to exercise their Underwriters' Warrant prior to the
initial filing of any registration statement or the effectiveness thereof,
provided that such Holders have made arrangements reasonably satisfactory to the
Company to pay the exercise price from the proceeds of such offering.

            (7)  The Company shall furnish to each Underwriter for the offering,
if any, such documents as such Underwriter may reasonably require.

            (8)  The Company shall as soon as practicable after the effective
date of the registration statement, and in any event within 15 months
thereafter, make "generally available to its security holders" (within the
meaning of Rule 158 under the Act) an earnings statement (which need not be
audited) complying with Section 11(a) of the Act and covering a period of at
least 12 consecutive months beginning after the effective date of the
registration statement.

            (9)  The Company shall deliver promptly to each Holder participating
in the offering requesting the correspondence described below and any managing
Underwriter copies of all correspondence between the Commission and the Company,
its counsel or auditors with respect to the registration statement and permit
each Holder and Underwriter to do such investigation, upon reasonable advance
notice, with respect to information contained in or omitted from the
registration statement as it deems reasonably necessary to comply with
applicable securities laws or rules of the National Association of Securities
Dealers, Inc. ("NASD"). Such investigation shall include access to books,
records and properties and opportunities to discuss the business of the Company
with its officers and independent auditors, all to such reasonable extent and at
such reasonable times and as often as any such Holder shall reasonably request.

            (10) The Company shall enter into an underwriting agreement with the
managing underwriter selected for such underwriting by Holders holding a
Majority of the Underwriters' Securities requested to be included in such
underwriting, provided, however that such managing underwriter shall be
reasonably acceptable to the Company, except that in connection with

                                       6

<PAGE>

an offering for which the Holders have piggyback rights, the Company shall have
the sole right to select the managing underwriter or underwriters. Such
underwriting agreement shall be satisfactory in form and substance to the
Company, a Majority of such Holders (in respect of a registration under Section
7(b) only) and such managing underwriter, and shall contain such
representations, warranties and covenants by the Company and such other terms as
are customarily contained in agreements of that type. The Holders shall be
parties to any underwriting agreement relating to an underwritten sale of their
Underwriters' Securities. Such Holders shall not be required to make any
representations or warranties to or agreements with the Company or the
underwriters except as they may relate to such Holders and their intended
methods of distribution.

         8. Adjustments to Purchase Price and Number of Securities.
            ------------------------------------------------------

            (a) Computation of Adjusted Purchase Price. Except as hereinafter
                --------------------------------------
provided, in case the Company shall at any time after the date hereof issue or
sell any shares of Common Stock (other than the issuances referred to in Section
8(g) hereof), including shares held in the Company's treasury, for a
consideration per share less than the "Market Price" (as defined in Section
8(a)(6) hereof) per share of Common Stock on the date immediately prior to the
issuance or sale of such shares, or without consideration, then forthwith upon
any such issuance or sale, the Purchase Price of the Common Stock shall (until
another such issuance or sale) be reduced to the price (calculated to the
nearest full cent) determined by dividing (1) the product of (a) the Purchase
Price in effect immediately before such issuance or sale and (b) the sum of (i)
the total number of shares of Common Stock outstanding immediately prior to such
issuance or sale, and (ii) the number of shares determined by dividing (A) the
aggregate consideration, if any, received by the Company upon such sale or
issuance, by (B) the Market Price, and by (2) the total number of shares of
Common Stock outstanding immediately after such issuance or sale provided,
however, that in no event shall the Purchase Price be adjusted pursuant to this
computation to an amount in excess of the Purchase Price in effect immediately
prior to such computation, except in the case of a combination of outstanding
shares of Common Stock, as provided by Section 8(c) hereof.

         For the purposes of this Section 8, the term "Purchase Price" shall
mean the Purchase Price of the Common Stock forming a part of the Underwriters'
Securities set forth in Section 6 hereof, as adjusted from time to time pursuant
to the provisions of this Section 8.

         For the purposes of any computation to be made in accordance with this
Section 8(a), the following provisions shall be applicable:

    (1)  In case of the issuance or sale of shares of Common Stock (or of
other securities deemed hereunder to involve the issuance or sale of shares of
Common Stock) for a consideration part or all of which shall be cash, the amount
of the cash consideration therefor shall be deemed to be the amount of cash
received by the Company for such shares (or, if shares of Common Stock are
offered by the Company for subscription, the subscription price, or, if such
securities shall be sold to Underwriters or dealers for public offering without
a subscription offering, the initial public offering price) before deducting
therefrom any compensation paid or discount allowed in the sale,

                                       7

<PAGE>

underwriting or purchase thereof by Underwriters or dealers or others performing
similar services, or any expenses incurred in connection therewith.

         (2) In case of the issuance or sale (otherwise than as a dividend or
other distribution on any stock of the Company, and otherwise than on the
exercise of options, rights or warrants or the conversion or exchange of
convertible or exchangeable securities) of shares of Common Stock (or of other
securities deemed hereunder to involve the issuance or sale of shares of Common
Stock) for a consideration part or all of which shall be other than cash, the
amount of the consideration therefor other than cash shall be deemed to be the
value of such consideration as determined in good faith by the Board of
Directors of the Company.

         (3) Shares of Common Stock issuable by way of dividend or other
distribution on any stock of the Company shall be deemed to have been issued
immediately after the opening of business on the day following the record date
for the determination of stockholders entitled to receive such dividend or other
distribution and shall be deemed to have been issued without consideration.

         (4) The reclassification of securities of the Company other than shares
of Common Stock into securities including shares of Common Stock shall be deemed
to involve the issuance of such shares of Common Stock for a consideration other
than cash immediately prior to the close of business on the date fixed for the
determination of security holders entitled to receive such shares, and the value
of the consideration allocable to such shares of Common Stock shall be
determined as provided in Section 8(a)(2).

         (5) The number of shares of Common Stock at any one time outstanding
shall include the aggregate number of shares of Common Stock issued or issuable
(subject to readjustment upon the actual issuance thereof) upon the exercise of
options, rights or warrants and upon the conversion or exchange of convertible
or exchangeable securities.

         (6) As used herein in the phrase "Market Price" at any date shall be
deemed to be the last reported sale price, or, in the case no such reported sale
takes place on such day, the average of the last reported sales prices for the
last three (3) trading days, in either case as officially reported by the
principal securities exchange on which the Common Stock is listed or admitted to
trading, or, if the Common Stock is not listed or admitted to trading on any
national securities exchange, the average closing bid price as furnished by the
NASD through the NASD Automated Quotation System ("NASDAQ") or similar
organization if NASDAQ is no longer reporting such information, or if the Common
Stock is not quoted on NASDAQ, as determined in good faith by resolution of the
Board of Directors of the Company, based on the best information available to
it.

                (b) Options, Rights, Warrant and Convertible and Exchangeable
                    ---------------------------------------------------------
Securities. Except in the case of the Company issuing rights to subscribe for
----------
shares of Common Stock distributed to all the stockholders of the Company and
Holders of Underwriters' Warrant pursuant to Section 8(i) hereof, if the Company
shall at any time after the date hereof issue options, rights or warrants to
purchase shares of Common Stock, or issue any securities convertible into or
exchangeable for shares of Common Stock (other than the issuances referred to in
Section 8(g) hereof), (i) for a consideration per share less than the Market
Price (including the issuance thereof

                                       8

<PAGE>

without consideration such as by way of dividend or other distribution), or (ii)
without consideration, the Purchase Price in effect immediately prior to the
issuance of such options, rights or warrants, or such convertible or
exchangeable securities, as the case may be, shall be reduced to a price
determined by making a computation in accordance with the provisions of Section
8(a) hereof, provided that:

                        (1) The aggregate maximum number of shares of Common
Stock issuable or that may become issuable under such options, rights or
warrants (assuming exercise in full even if not then currently exercisable or
currently exercisable in full) shall be deemed to be issued and outstanding at
the time such options, rights or warrants were issued, and for a consideration
equal to the minimum purchase price per share provided for in such options,
rights or warrants at the time of issuance, plus the consideration (determined
in the same manner as consideration received on the issue or sale of shares in
accordance with the terms of the Underwriters' Warrant), if any, received by the
Company for such options, rights or warrants; provided, however, that upon the
expiration or other termination of such options, rights or warrants, if any
thereof shall not have been exercised, the number of shares of Common Stock
deemed to be issued and outstanding pursuant to this Section 8(b)(1) (and for
the purposes of Section 8(a)(5) hereof) shall be reduced by such number of
shares as to which options, warrants and/or rights shall have expired or
terminated unexercised, and such number of shares shall no longer be deemed to
be issued and outstanding, and the Purchase Price then in effect shall forthwith
be readjusted and thereafter be the price which it would have been had
adjustment been made on the basis of the issuance only of shares actually issued
or issuable upon the exercise of those options, rights or warrants as to which
the exercise rights shall not be expired or terminated unexercised.

                        (2) The aggregate maximum number of shares of Common
Stock issuable upon conversion or exchange of any convertible or exchangeable
securities (assuming conversion or exchange in full even if not then currently
convertible or exchangeable in full) shall be deemed to be issued and
outstanding at the time of issuance of such securities, and for a consideration
equal to the consideration (determined in the same manner as consideration
received on the issue or sale of shares of Common Stock in accordance with the
terms of the Underwriters' Warrant) received by the Company for such securities,
plus the minimum consideration, if any, receivable by the Company upon the
conversion or exchange thereof; provided, however, that upon the expiration or
other termination of the right to convert or exchange such convertible or
exchangeable securities (whether by reason or redemption or otherwise), the
number of shares deemed to be issued and outstanding pursuant to this Section
8(b)(2) (and for the purpose of Section 8(a)(5) hereof) shall be reduced by such
number of shares as to which the conversion or exchange rights shall have
expired or terminated unexercised, and such number of shares shall no longer be
deemed to be issued and outstanding and the Purchase Price then in effect shall
forthwith be readjusted and thereafter be the price which it would have been had
adjustment been made on the basis of the issuance only of the shares actually
issued or issuable upon the conversion or exchange of those convertible or
exchangeable securities as to which the conversion or exchange rights shall not
have expired or terminated unexercised.

                        (3) If any change shall occur in the price per share
provided for in

                                       9

<PAGE>

any of the options, rights or warrants referred to in Section 8(b)(1), or in the
price per share at which the securities referred to in Section 8(b)(2) are
convertible or exchangeable, and if a change in the Purchase Price has not
occurred by reason of the event giving rise to the change in the price per share
of such other options, rights, warrants, or convertible or exchangeable
securities, such options, rights or warrants or conversion or exchange rights,
as the case may be, to the extent not theretofore exercised, the shall be deemed
to have expired or terminated on the date when such price change became
effective in respect of shares not theretofore issued pursuant to the exercise
or conversion or exchange thereof, and the Company shall be deemed to have
issued upon such date new options, rights or warrants or convertible or
exchangeable securities at the new price in respect of the number of shares
issuable upon the exercise of such options, rights or warrants or the conversion
or exchange of such convertible or exchangeable securities.

            (c) Subdivision and Combination. In case the Company shall at any
                ---------------------------
time issue any shares of Common Stock in connection with a stock dividend in
shares of Common Stock or subdivide or combine the outstanding shares of Common
Stock, the Purchase Price shall forthwith be proportionately decreased in the
case of a stock dividend or a subdivision or increased in the case of
combination.

            (d) Adjustment in Number of Securities. Upon each adjustment of the
                ----------------------------------
Purchase Price pursuant to the provisions of this Section 8, the number of
Underwriters' Securities issuable upon the exercise of the Underwriters' Warrant
shall be adjusted to the nearest whole share by multiplying a number equal to
the Purchase Price in effect immediately prior to such adjustment by the number
of Underwriters' Securities issuable upon exercise of the Underwriters' Warrant
immediately prior to such adjustment and dividing the product so obtained by the
adjusted Purchase Price.

            (e) Definition of Common Stock. For the purpose of this Agreement,
                --------------------------
the term "Common Stock" shall mean the class of stock designated as Common Stock
in the Certificate of Incorporation, of the Company as it may be amended as of
the date hereof.

            (f) Reclassification, Merger or Consolidation. The Company will not
                -----------------------------------------
merge, reorganize or take any other action which would terminate the
Underwriters' Warrant without first making adequate provision for the
Underwriters' Warrant. In case of any reclassification or change of the
outstanding shares of Common Stock issuable upon exercise of the outstanding
warrants (other than a change in par value to no par value, or from nor par
value to par value, or as a result of a subdivision or combination), or in case
of any consolidation of the Company with, or merger of the Company with, or
merger of the Company into, another corporation (other than a consolidation or
merger in which the Company is the continuing corporation and which does not
result in any reclassification or change of the outstanding Common Stock except
a change as a result of a subdivision or combination of such shares or a change
in par value, as aforesaid), or in the case of a sale or conveyance to another
corporation or other entity of the property of the Company as an entirety or
substantially as an entirety, the Holders of each Underwriters' Warrant then
outstanding or to be outstanding shall have the right thereafter (until the
expiration of such Underwriters' Warrant) to purchase, upon exercise of such
Underwriters' Warrant, the kind and number of shares of stock

                                       10

<PAGE>

and other securities and property receivable upon such reclassification, change,
consolidation, merger, sale or conveyance as if the Holders were the owner of
the shares of Common Stock underlying the Underwriters' Warrant immediately
prior to any such events at a price equal to the product of (x) the number of
shares issuable upon exercise of the Underwriters' Warrant and (y) the Purchase
Price in effect immediately prior to the record date for such reclassification,
change, consolidation, merger, sale or conveyance, as if such Holders had
exercised the Underwriters' Warrant. In the event of a consolidation, merger,
sale or conveyance of property, the corporation formed by such consolidation or
merger, or acquiring such property, shall execute and deliver to the Holders a
supplemental Underwriters' warrant agreement to such effect. Such supplemental
Underwriters' warrant agreement shall provide for adjustments which shall be
identical to the adjustment provided for in this Section 8. The provisions of
this Section 8(f) shall similarly apply to successive consolidations or mergers.

            (g) No Adjustment of Purchase Price in Certain Cases. No adjustment
                ------------------------------------------------
of the Purchase Price shall be made:

                (1)  Upon the issuance or sale of (i) the Underwriters'
Warrant or the securities underlying the Underwriters' Warrant, (ii) the
securities sold pursuant to the Public Offering (including those sold upon
exercise of the Underwriters' over-allotment option), or (iii) the shares
issuable pursuant to the options, warrants, rights, stock purchase agreements or
convertible or exchangeable securities outstanding or in effect on the date
hereof as described in the prospectus relating to the Public Offering.

                (2)  If the amount of said adjustments shall aggregate
less than two ($.02) cents for one (1) share of Common Stock; provided, however,
that in such case any adjustment that would otherwise be required then to be
made shall be carried forward and shall be made at the time of and together with
the next subsequent adjustment which, together with any adjustment so carried
forward, shall aggregate at least two ($.02) cents for one (1) share of Common
Stock. In addition, Registered Holders shall not be entitled to cash dividends
paid by the Company prior to the exercise of any warrant or warrants held by
them.

            9.  Exchange and Replacement of Warrant Certificates. Each
Underwriters' Warrant Certificate is exchangeable without expense, upon the
surrender thereof by the registered Holders at the principal executive office of
the Company, for a new Underwriters' Warrant Certificate of like tenor and date
representing in the aggregate the right to purchase the same number of
Underwriters' Securities in such denominations as shall be designated by the
Holders thereof at the time of such surrender.

            10. Loss, Theft etc. of Certificates Upon receipt by the Company of
evidence reasonably satisfactory to it of the loss, theft, destruction or
mutilation of any Underwriters' Warrant Certificate, and, in case of loss, theft
or destruction, of indemnity or security reasonably satisfactory to it, and
reimbursement to the Company of all reasonable expenses incidental thereto, and
upon surrender and cancellation of the Underwriters' Warrant Certificates, if
mutilated, the Company will make and deliver a new Underwriters' Warrant
Certificate of like tenor, in lieu thereof.

                                       11

<PAGE>

            11. Elimination of Fractional Interests. The Company shall not be
                -----------------------------------
required to issue certificates representing fractions of shares of Common Stock
upon the exercise of the Underwriters' Warrant, nor shall it be required to
issue scrip or pay cash in lieu of fractional interests; provided, however, that
if a Holder exercises all Underwriters' Warrant held of record by such Holder
the fractional interests shall be eliminated by rounding any fraction to the
nearest whole number of shares of Common Stock or other securities, properties
or rights.

            12. Reservation and Listing of Securities. The Company shall at all
                -------------------------------------
times reserve and keep available out of its authorized shares of Common Stock,
solely for the purpose of issuance upon the exercise of the Underwriters'
Warrant, such number of shares of Common Stock or other securities and
properties or rights as shall be issuable upon the exercise thereof. The Company
covenants and agrees that, upon exercise of Underwriters' Warrant and payment of
the Purchase Price therefor, all the shares of Common Stock issuable upon such
exercise shall be duly and validly issued, fully paid, non-assessable and not
subject to the preemptive rights of any stockholder. As long as the
Underwriters' Warrant shall be outstanding, the Company shall use its best
efforts to cause the Common Stock to be listed (subject to official notice of
issuance) on all securities exchanges on which the Common Stock issued to the
public in connection herewith may then be listed or quoted.

            13. Notices to Underwriters' Warrant Holders. Nothing contained in
                ----------------------------------------
this Agreement shall be construed as conferring upon the Holders the right to
vote or to consent or to receive notice as a stockholder in respect of any
meetings of stockholders for the election of directors or any other matter, or
as having any rights whatsoever as a stockholder of the Company. If, however, at
any time prior to the expiration of the Underwriters' Warrant and their
exercise, any of the following events shall occur:

                (a) the Company shall take a record of the holders of its shares
of Common Stock for the purpose of entitling them to receive a dividend or
distribution payable otherwise than in cash, or a cash dividend or distribution
payable otherwise than out of current or retained earnings, as indicated by the
accounting treatment of such dividend or distribution on the books of the
Company; or

                (b) the Company shall offer to all the holders of its Common
Stock any additional shares of capital stock of the Company or securities
convertible into or exchangeable for shares of capital stock of the Company, or
any option, right or warrant to subscribe therefor; or

                (c) a dissolution, liquidation or winding up of the Company
(other than in connection with a consolidation or merger) or a sale of all or
substantially all of its property, assets and business as an entirety shall be
proposed; then, in any one or more of said events, the Company shall give
written notice of such event at least fifteen (15) calendar days prior to the
date fixed as a record date or the date of closing the transfer books for the
determination of the stockholders entitled to such dividend, distribution,
convertible or exchangeable securities or subscription rights, or entitled to
vote on such proposed dissolution, liquidation, winding up or sale. Such notice
shall

                                       12

<PAGE>

specify such record date or the date of closing the transfer books, as the case
may be. Failure to give such notice or any defect therein shall not affect the
validity of any action taken in connection with the declaration or payment of
any such dividend, or the issuance of any convertible or exchangeable
securities, or subscription rights, options or warrants, or any proposed
dissolution, liquidation, winding up or sale.

            14. Notices. All notices, requests, consents and other
                -------
communications hereunder shall be in writing and shall be deemed to have been
duly made when delivered, or five days after being mailed by registered or
certified mail, return receipt requested:

If to the registered Holders of the Underwriters' Warrant, to the address of
such Holders as shown on the books of the Company; or

                (a) If to the Company to 6925 112/th/ Circle North Suite 102,
Largo, Florida 33773 or to such other address as the Company may designate by
notice to the Holders.

            15. Supplements and Amendments. The Company and the Underwriter may
                --------------------------
from time to time supplement or amend this Agreement without the approval of any
Holders of Underwriters' Warrant Certificates (other than the Underwriters) in
order to cure any ambiguity, to correct or supplement any provision contained
herein which may be defective or inconsistent with any provisions herein, or to
make any other provision in regard to matters or questions arising hereunder
which the Company and the Underwriters may deem necessary or desirable and which
the Company and the Underwriters deem shall not adversely affect the interests
of the Holders of Underwriters' Warrant Certificates.

            16. Successors. All the covenants and provisions of this Agreement
                ----------
shall be binding upon and inure to the benefit of the Company, the Underwriter,
the Holders and their respective successors and assigns hereunder.

            17. Termination. This Agreement shall terminate at the close of
                -----------
business on _______, 2007. Notwithstanding the foregoing, the indemnification
provisions of Section 7 shall survive such termination until the close of
business on the expiration of any applicable statue of limitations.

            18. Governing Law; Submission to Jurisdiction. This Agreement and
                -----------------------------------------
each Underwriters' Warrant Certificate issued hereunder shall be deemed to be a
contract made under the laws of the State of New York and for all purposes shall
be construed in accordance with the laws of said state without giving effect to
the rules of said state governing the conflicts of laws.

            19. Entire Agreement; Modification. This Agreement (including the
                -------------------------------
Underwriting Agreement, to the extent portions thereof are referred to herein)
contains the entire understanding between the parties hereto with respect to the
subject matter hereof and thereof. This Agreement may not be modified or amended
except by a writing duly signed by the Company and the Holders of a Majority in
Interest of the Underwriters' Securities (for this purpose, treating all then
outstanding Underwriters' Warrants as if they had been exercised).

                                       13

<PAGE>
            20. Severability. If any provision of this Agreement shall be held
                ------------
to be invalid or unenforceable, such invalidity or unenforceability shall not
affect any other provision of this Agreement.

            21. Captions. The caption headings of the Sections of this Agreement
                --------

                --------------------------
construed to give to any person or corporation other than the Company and the
Underwriter and any other registered Holders of the Underwriters' Warrant
Certificates or Underwriters' Securities any legal or equitable right, remedy or
claim under this Agreement; and this Agreement shall be for the sole and
exclusive benefit of the Company and the Underwriter and any other Holders of
the Underwriters' Warrant Certificates or Underwriters' Securities.

            23. Counterparts. This Agreement may be executed in any number of
                ------------
counterparts and each of such counterparts shall for all purposes be deemed to
be an original, and such counterparts shall together constitute but one and the
same instrument.

            24. Binding Effect. This Agreement shall be binding upon and inure
                --------------
to the benefit of the Company, the Underwriters and their respective successors

                  5:00 P.M., NEW YORK TIME ON __________, 2007


                                             Warrant covering 135,000 shares of
                                             Common Stock

No. UW-1

         This Warrant Certificate certifies that Kashner Davidson Securities
Corp. or registered assigns, is the registered holder of this Warrant to
purchase initially, at any time from _________, 2003, until 5:00 p.m., New York

Stock, $.001 par value (the "Common Stock") of Vertical Health Solutions, Inc.
("Company") exercisable to purchase one share of Common Stock at a purchase
price of $9.90 per share (165% of the per share public offering price) (the
"Purchase Price"), upon the surrender of this Warrant Certificate and payment of
the applicable Purchase Price at an office or agency of the Company, but subject
to the conditions set forth herein and in the Underwriters' Warrant Agreement,
dated as of ________, 2002, by and between the Company and Kashner Davidson
Securities Corp. (the "Warrant Agreement"). Payment of the Purchase Price shall
be made by certified or cashier's check or money order payable to the order of
the Company or through a cashless exercise by surrending the Warrant Certificate
pursuant to the Underwriter Agreement.

         No Warrant may be exercised after 5:00 p.m., New York time, on the
Expiration Date, at which time all Warrant evidenced hereby, unless exercised
prior thereto, shall thereafter be void.

         The Warrant evidenced by this Warrant Certificate is part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement between
the Company and the Underwriter, which Warrant Agreement is hereby incorporated
by reference in and made a part of this instrument

                                       17

<PAGE>

and is hereby referred to for a description of the rights, limitation of rights,
obligations, duties and immunities thereunder of the Company and the holders
(the words "holders" or "holder" meaning the registered holders or registered
holder) of the Warrant.

         The Warrant Agreement provides that upon the occurrence of certain
events the Purchase Price and the type and/or number of the Company's securities
issuable upon the exercise of this Warrant, may, subject to certain conditions,
be adjusted. In such event, the Company will, at the request of the holder,
issue a new Warrant Certificate evidencing the adjustment in the Purchase Price
and the number and/or type of securities issuable upon the exercise of the
Warrant; provided, however, that the failure of the Company to issue such new
Warrant Certificates shall not in any way change, alter, or otherwise impair,
the rights of the holder as set forth in the Warrant Agreement.

         Upon due presentment for registration of transfer of this Warrant
Certificate at an office or agency of the Company, a new Warrant Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number
of Warrant shall be issued to the transferee(s) in exchange as provided herein,
without any charge except for any tax or other governmental charge imposed in
connection with such transfer.

         Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such number of unexercised Warrants.

         The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

         All terms used in this Warrant Certificate which are defined in the
Warrant Agreement shall have the meanings assigned to them in the Warrant
Agreement.

         IN WITNESS WHEREOF, the undersigned has executed this certificate this
