         Section 7.2 Conditions Precedent to the Right of the Company to Deliver
a Put Notice and the Obligation of the Investors to Purchase Put Shares. The
right of the Company to deliver a Put Notice and the obligation of the Investors
hereunder to acquire and pay for the Put Shares incident to a Closing is subject
to the satisfaction, on (i) the date of delivery of such Put Notice and (ii) the
applicable Closing Date (each a "Condition Satisfaction Date"), of each of the
following conditions:

      (a) Registration of the Common Stock with the SEC. The Company shall have
filed with the SEC a Registration Statement with respect to the resale of at
least that amount of Registrable Securities contained in the Put Notice in
accordance with the terms of the Registration Rights Agreement. As set forth in
the Registration Rights Agreement, the Registration Statement shall have
previously become effective and shall remain effective on each Condition
Satisfaction Date and (i) neither the Company nor the Investors shall have
received notice that the SEC has issued or intends to issue a stop order with
respect to the Registration Statement or that the SEC otherwise has suspended or
withdrawn the effectiveness of the Registration Statement, either temporarily or
permanently, or intends or has threatened to do so (unless the SEC's concerns
have been addressed and the Investors are reasonably satisfied that the SEC no
longer is considering or intends to take such action), and (ii) no other
suspension of the use or withdrawal of the effectiveness of the Registration
Statement or related prospectus shall exist. The Registration Statement must
have been declared effective by the SEC prior to the first and each subsequent
Put Date.

      (b) Authority. The Company shall have obtained all permits and
qualifications required by any state for the offer and sale of the Put Shares,
or shall have the availability of exemptions therefrom. The sale and issuance of
the Put Shares shall be legally permitted by all laws and regulations to which
the Company is subject.

      (c) Accuracy of the Company's Representations and Warranties. The
representations and warranties of the Company shall be true and correct in all
material respects as of each Condition Satisfaction Date as though made at each
such time (except for representations and warranties specifically made as of a
particular date) with respect to all periods, and as to all events and
circumstances occurring or existing to and including each Condition Satisfaction
Date, except for any conditions which have temporarily caused any
representations or warranties herein to be incorrect and which have been
corrected with no continuing impairment to the Company or the Investors.

      (d) Performance by the Company. The Company shall have performed,
satisfied and complied in all material respects with all covenants, agreements
and conditions required by this Agreement, the Registration Rights Agreement and
the Warrant to be performed, satisfied or complied with by the Company at or
prior to each Condition Satisfaction Date.

                                       17
<PAGE>

      (e) No Injunction. No statute, rule, regulation, executive order, decree,
ruling or injunction shall have been enacted, entered, promulgated or endorsed
by any court or governmental authority of competent jurisdiction that prohibits
or directly and adversely affects any of the transactions contemplated by this
Agreement, and no proceeding shall have been commenced that may have the effect
of prohibiting or adversely affecting any of the transactions contemplated by
this Agreement.

      (f) Adverse Changes. Since the Subscription Date, no event that had or is
reasonably likely to have a Material Adverse Effect has occurred.

      (g) No Suspension of Trading In or Delisting of Common Stock. The trading
of the Common Stock (including, without limitation, the Put Shares) is not
suspended by the SEC or the Principal Market, and the Common Stock (including,
without limitation, the Put Shares) shall have been approved for listing or
quotation on and shall not have been delisted from the Principal Market. The
issuance of shares of Common Stock with respect to the applicable Closing, if
any, shall not violate the shareholder approval requirements of the Principal
Market. The Company shall not have received any notice threatening the listing
of the Common Stock on the Principal Market.

      (h) 4.99% Percent Limitation. On each Closing Date, the number of Put
Shares then to be purchased by each Investor will not exceed the number of such
shares which, when aggregated with all other shares of Common Stock then owned
by such Investor beneficially or deemed beneficially owned by such Investor,
would result in any Investor owning more than 4.99% of all of such Common Stock
as would be outstanding on such Closing Date, as determined in accordance with
Rule 13d-3 of the Exchange Act and the regulations promulgated thereunder. For
purposes of this Section 7.2(j), in the event that the amount of Common Stock
outstanding as determined in accordance with Rule 13d-3 of the Exchange Act and
the regulations promulgated thereunder is greater on a Closing Date than on the
date upon which the Put Notice associated with such Closing Date is given, the
amount of Common Stock outstanding on such Closing Date shall govern for
purposes of determining whether any Investor, when aggregating all purchases of
Common Stock made pursuant to this Agreement and, if any, Warrant Shares, would
own more than 4.99% of the Common Stock following such Closing. Then, in such
event, the Company would reduce that number of Put Shares so issuable so that it
would not exceed the aforementioned 4.99% limitation. Such Investor shall notify
the Company as soon as possible, but in any event within three (3) business days
of receiving a Put Notice, if such Investor believes Investor's purchase of the
Put Shares specified in the Put Notice would result in any Investor exceeding
the 4.99% limitation described above.

                                       18
<PAGE>

      (i) Minimum Bid Price. The Bid Price equals or exceeds the Floor Price
during the applicable Valuation Period (as adjusted for stock splits, stock
dividends, reverse stock splits, and similar events).

      (j) Minimum Average Trading Volume. The average trading volume for the
Common Stock over the previous thirty (30) Trading Days exceeds 25,000 shares
per Trading Day.

      (k) No Knowledge. The Company has no knowledge of any event more likely
than not to have the effect of causing such Registration Statement to be
suspended or otherwise ineffective (which event is more likely than not to occur
within the fifteen Trading Days following the Trading Day on which such Notice
is deemed delivered).

      (l) Trading Cushion. The Trading Cushion shall have elapsed since the next
preceding Put Date.

      (m)Escrow Agreement. The parties hereto shall have entered into a
mutually acceptable escrow agreement for the Purchase Prices due hereunder.

      (n) Other. On each Condition Satisfaction Date, the Investors shall have
received and been reasonably satisfied with such other certificates and
documents as shall have been reasonably requested by any Investor in order for
such Investor to confirm the Company's satisfaction of the conditions set forth
in this Section 7.2, including, without limitation, a certificate in
substantially the form and substance of Exhibit C hereto, executed in either
case by an executive officer of the Company and to the effect that all the
conditions to such Closing shall have been satisfied as at the date of each such
certificate.

                                   ARTICLE VII
         Due Diligence Review; Non-Disclosure of Non-Public Information

         Section 8.1 Due Diligence Review. The Company shall make available for
inspection and review by the Investors, advisors to and representatives of the
Investors (who may or may not be affiliated with the Investors and who are
reasonably acceptable to the Company), any underwriter participating in any
disposition of the Registrable Securities on behalf of the Investors pursuant to
the Registration Statement, any such registration statement or amendment or
supplement thereto or any blue sky, NASD or other filing, all financial and
other records, all SEC Documents and other filings with the SEC, and all other
corporate documents and properties of the Company as may be reasonably necessary
for the purpose of such review, and cause the Company's officers, directors and
employees to supply all such information reasonably requested by the Investors
or any such representative, advisor or underwriter in connection with such
Registration Statement (including, without limitation, in response to all
questions and other inquiries reasonably made or submitted by any of them),
prior to and from time to time after the filing and effectiveness of the
Registration Statement for the sole purpose of enabling the Investors and such
representatives, advisors and underwriters and their respective accountants and
attorneys to conduct initial and ongoing due diligence with respect to the
Company and the accuracy of the Registration Statement.

         Section 8.2  Non-Disclosure of Non-Public Information

         (a) The Company shall not disclose non-public information to the
Investors, advisors to or representatives of the Investors (including, without
limitation, in connection with the giving of the Adjustment Period Notice
pursuant to Section 2.4) unless prior to disclosure of such information the
Company identifies such information as being non-public information and provides
the Investors, such advisors and representatives with the opportunity to accept
or refuse to accept such non-public information for review. The Company may, as
a condition to disclosing any non-public information hereunder, require the
Investor's advisors and representatives to enter into a confidentiality
agreement in form reasonably satisfactory to the Company and the Investors.

         (b) Nothing herein shall require the Company to disclose non-public
information to the Investors or their advisors or representatives, and the
Company represents that it does not disseminate non-public information to any
investors who purchase stock in the Company in a public offering, to money
managers or to securities analysts, provided, however, that notwithstanding
anything herein to the contrary, the Company will, as hereinabove provided,
immediately notify the advisors and representatives of the Investors and, if
any, underwriters, of any event or the existence of any circumstance (without
any obligation to disclose the specific event or circumstance) of which it
becomes aware, constituting non-public information (whether or not requested of
the Company specifically or generally during the course of due diligence by such
persons or entities), which, if not disclosed in the prospectus included in the
Registration Statement would cause such prospectus to include a material
misstatement or to omit a material fact required to be stated therein in order
to make the statements, therein, in light of the circumstances in which they
were made, not misleading. Nothing contained in this Section 8.2 shall be
construed to mean that such persons or entities other than the Investors
(without the written consent of the Investors prior to disclosure of such
information) may not obtain non-public information in the course of conducting
due diligence in accordance with the terms of this Agreement and nothing herein
shall prevent any such persons or entities from notifying the Company of their
opinion that based on such due diligence by such persons or entities, that the
Registration Statement contains an untrue statement of a material fact or omits
a material fact required to be stated in the Registration Statement or necessary
to make the statements contained therein, in light of the circumstances in which
they were made, not misleading.


                                   ARTICLE IX
                           Choice of Law/Jurisdiction

                  Section 9.1 Choice of Law; Venue; Jurisdiction. This Agreement
will be construed and enforced in accordance with and governed by the laws of
the State of Florida, except for matters arising under the Act, without
reference to principles of conflicts of law. The party who initiates legal
action shall choose the jurisdiction of the federal courts in connection with
any dispute arising under this Agreement and hereby waives, to the maximum
extent permitted by law, any objection, including any objection based on forum
non conveniens, to the bringing of any such proceeding in such jurisdictions.
Each party waives its right to a trial by jury. Each party hereby agrees that if
another party to this Agreement obtains a judgment against it in such a
proceeding, the party which obtained such judgment may enforce same by summary
judgment in the courts of any country having jurisdiction over the party against
whom such judgment was obtained, and each party hereby waives any defenses
available to it under local law and agrees to the enforcement of such a
judgment. Each party to this Agreement irrevocably consents to the service of
process in any such proceeding by the mailing of copies thereof by registered or
certified mail, postage prepaid, to such party at its address set forth herein.
Nothing herein shall affect the right of any party to serve process in any other
manner permitted by law.


                                    ARTICLE X
                             Assignment; Termination

         Section 10.1 Assignment. Neither this Agreement nor any rights of the
Investors or the Company hereunder may be assigned by either party to any other
person. Notwithstanding the foregoing, (a) the provisions of this Agreement
shall inure to the benefit of, and be enforceable by, any transferee of any of
the Common Stock purchased or acquired by the Investors hereunder with respect
to the Common Stock held by such person, and (b) upon the prior written consent
of the Company, which consent shall not unreasonably be withheld, the Investors
interest in this Agreement may be assigned at any time, in whole or in part, to
any other person or entity (including any affiliate of the Investors) who agrees
to make the representations and warranties contained in Article III and who
agrees to be bound by the covenants of Article V.

                                           REGISTRATION RIGHTS AGREEMENT


                  THIS REGISTRATION RIGHTS AGREEMENT, dated the __ day of
October, 1998, between the entities listed on Schedule A attached hereto
(referred to as a "Purchaser" or "Purchasers"), SETTONDOWN CAPITAL INTERNATIONAL
LTD. (the "Placement Agent" together with the Purchasers is also hereinafter
referred to as the "Holder") located at Charlotte House, Charlotte Street, P.O.
Box N. 9204, Nassau, Bahamas, a corporation organized under the laws of Bahamas,
GOLDSTEIN, GOLDSTEIN & REIS, LLP ("GGR" and together with the Purchasers and the
Placement Agent also referred to as a "Holder") and IMAGING DIAGNOSTIC SYSTEMS,
INC., a corporation incorporated under the laws of the state of Florida, and
having its principle place of business at 6531 NW 18th Court, Plantation,
Florida 33313, (the "Company").

                  WHEREAS, simultaneously with the execution and delivery of
this Agreement, the Purchasers are purchasing from the Company, pursuant to a
Private Equity Line of Credit Agreement dated the date hereof (the "Equity Line
Agreement"), (i) an aggregate of up to Fifteen Million ($15,000,000) Dollars
principal amount of shares of Common Stock, (ii) a Warrant A to purchase twenty
five thousand (25,000) shares of the Company's Common Stock, and (iii) a Warrant
B to purchase twenty five thousand (25,000) shares of the Company's Common
Stock. All capitalized terms not hereinafter defined shall have that meaning
assigned to them in the Equity Line Agreement; and

                  WHEREAS, the Company has agreed to pay to the Placement Agent
for services rendered, 6% of the gross proceeds of each Put, payable in the form
of Common Stock that will be registered at the same time as the Put Shares. In
addition, the Placement Agent shall receive, on a pro rata basis as the Equity
Line of Credit is drawn upon, (a) a Warrant A to purchase up to fifty thousand
(50,000)) shares of Common Stock upon the same terms as the Warrant A issued to
the Purchasers pursuant to the Equity Line Of Credit Agreement (whose Warrant
Shares will be registered at the same time as the Put Shares), and (b) eighty
thousand (80,000) shares of Common Stock which be registered at the same time as
the Put Shares; and

                  WHEREAS, the Company has agreed to pay to GGR for services
rendered, fifty thousand (50,000) shares of Common Stock ("GGR Shares") to be
registered at the same time as the Put Shares; and

                  WHEREAS, the Company desires to grant to the Holders the
registration rights set forth herein with respect to the Put Shares, the Common
Stock and Warrant Shares to be issued to the Placement Agent, and the shares of
Common Stock underlying Warrants (hereinafter referred to as the "Stock" or
"Securities" of the Company).

                  NOW, THEREFORE, the parties hereto mutually agree as follows:

                  Section 1. Registrable Securities. As used herein the term
"Registrable Security" means the Securities; provided, however, that with
respect to any particular Registrable Security, such security shall cease to be
a Registrable Security when, as of the date of determination, (i) it has been
effectively registered under the Securities Act of 1933, as amended (the "1933
Act") and disposed of pursuant thereto, (ii) registration under the 1933 Act is
no longer required for the immediate public distribution of such security as a
result of the provisions of Rule 144 promulgated under the 1933 Act, or (iii) it
has ceased to be outstanding. The term "Registrable Securities" means any and/or
all of the securities falling within the foregoing definition of a "Registrable
Security." In the event of any merger, reorganization, consolidation,
recapitalization or other change in corporate structure affecting the Common
Stock, such adjustment shall be made in the definition of "Registrable Security"
as is appropriate in order to prevent any dilution or enlargement of the rights
granted pursuant to this Section 1.

           Section 2. Restrictions on Transfer. The Holders acknowledge and
understand that prior to the registration of the Securities as provided herein,
the Securities are "restricted securities" as defined in Rule 144 promulgated
under the Act. The Holders understand that no disposition or transfer of the

                                       1
<PAGE>

Securities may be made by Holders in the absence of (i) an opinion of counsel to
the Holders that such transfer may be made without registration under the 1933
Act or (ii) such registration.

           Section 3.  Registration Rights.

                (a) The Company agrees that it will prepare and file and cause
to become effective with the Securities and Exchange Commission ("Commission")
an amendment (the "Amendment") to the Form S-2 registration statement (which was
filed by the Company on _____) at the sole expense of the Company (except as
provided in Section 3(c) hereof), registering the GGR Shares and the shares of
Common Stock underlying the Warrants issued to the Purchasers on the
Subscription Date, in respect of GGR and the Purchasers. The Company also agrees
that, prior to each Put Closing it will prepare and file and cause to become
effective with the Commission , a registration statement (on Form S-2, or other
appropriate registration statement) under the 1933 Act (the "Registration
Statement"), at the sole expense of the Company (except as provided in Section
3(c) hereof), registering that amount of Common Stock, and the Common Stock
underlying the Warrants, associated with that Put Closing, in respect of all
holders of Registrable Securities, so as to permit a public offering and sale of
the Registrable Securities associated with the Put Closings, under the Act.

                (b) The Company will maintain the Registration Statement or
post-effective amendment filed under this Section 3 hereof current under the
1933 Act until the earlier of (i) the date that all of the Registrable
Securities have been sold pursuant to the Registration Statement, (ii) the date
the holders thereof receive an opinion of counsel that the Registrable
Securities may be sold under the provisions of Rule 144 or (iii) five and one
half years after the date the applicable Registration Statement is filed. The
Company will maintain the Amendment or post-effective amendment filed under this
Section 3 hereof current under the 1933 Act until the earlier of (i) the date
that all of the GGR Shares and the shares of Common Stock underlying the
Warrants issued to the Purchasers on the Subscription Date have been sold by
such people pursuant to the Amendment, (ii) the date the holders thereof receive
an opinion of counsel that the GGR Shares and the shares of Common Stock
underlying the Warrants issued to the Purchasers on the Subscription Date may be
sold under the provisions of Rule 144 or (iii) five and one half years after the
Subscription Date.

                (c) All fees, disbursements and out-of-pocket expenses and costs
incurred by the Company in connection with the preparation and filing of the
Amendment and the Registration Statement under subparagraph 3(a) and in
complying with applicable securities and Blue Sky laws (including, without
limitation, all attorneys' fees) shall be borne by the Company. The Holders
shall bear the cost of underwriting discounts and commissions, if any,
applicable to the Registrable Securities being registered and the fees and
expenses of its counsel. The Company shall qualify any of the securities for
sale in such states as such Holder reasonably designates and shall furnish
indemnification in the manner provided in Section 6 hereof. However, the Company
shall not be required to qualify in any state which will require an escrow or
other restriction relating to the Company and/or the sellers. The Company at its
expense will supply the Holders with copies of the Registration Statement and
the prospectus or offering circular included therein and other related documents
in such quantities as may be reasonably requested by the Holders.

                (d) The Company shall not be required by this Section 3 to
include a Holder's Registrable Securities or GGR Shares and the shares of Common
Stock underlying the Warrants issued to the Purchasers on the Subscription Date
in any Amendment or Registration Statement which is to be filed if, in the
opinion of counsel for both the Holders and the Company (or, should they not
agree, in the opinion of another counsel experienced in securities law matters
acceptable to counsel for the Holders and the Company) the proposed offering or
other transfer as to which such registration is requested is exempt from
applicable federal and state securities laws and would result in all purchasers
or transferees obtaining securities which are not "restricted securities", as
defined in Rule 144 under the 1933 Act.

                                       2
<PAGE>

                (e) No provision contained herein shall preclude the Company
from selling securities pursuant to any Registration Statement in which it is
required to include Registrable Securities pursuant to this Section 3.

                (f) The Company agrees that it will declare the Amendment and/or
the Registration Statement effective within five business days after being
notified by the Commission that it may do so.

                (e) In the event the Amendment to be filed by the Company
pursuant to Section 3(a) above is not filed with the Commission within fifteen
(15) days from the Subscription Date and/or the Amendment is not declared
effective by the Commission within forty five (45) days from the Subscription
Date, then the Company will pay GGR and the Purchasers (pro rated on a daily
basis), as liquidated damages for such failure and not as a penalty, two (2%)
percent of the purchase price of the then outstanding Securities for every
thirty (30) day period until the Amendment has been filed and/or declared
effective. Such payment of the liquidated damages shall be made to the GGR and
the Purchasers in cash, immediately upon demand, provided, however, that the
payment of such liquidated damages shall not relieve the Company from its
obligations to register the Securities pursuant to this Section.

                  If the Company does not remit the damages as set forth above,
the Company will pay the reasonable costs of collection, including attorneys
fees, in addition to the liquidated damages. The registration of the Securities
pursuant to this provision shall not affect or limit other rights or remedies of
GGR and the Purchasers as set forth in this Agreement.


           Section 4. Cooperation with Company. The Holders will cooperate with
the Company in all respects in connection with this Agreement, including timely
supplying all information reasonably requested by the Company and executing and
returning all documents reasonably requested in connection with the registration
and sale of the Registrable Securities, the GGR Shares and the shares of Common
Stock underlying the Warrants issued to the Purchasers on the Subscription Date.

           Section 5. Registration Procedures. If and whenever the Company is
required by any of the provisions of this Agreement to effect the registration
of any of the Registrable Securities or the GGR Shares and the shares of Common
Stock underlying the Warrants issued to the Purchasers on the Subscription Date
under the Act, the Company shall (except as otherwise provided in this
Agreement), as expeditiously as possible:

                (a) prepare and file with the Commission such amendments and
supplements to the Amendment and/or Registration Statement and the prospectus
used in connection therewith as may be necessary to keep such registration
statement effective and to comply with the provisions of the Act with respect to
the sale or other disposition of all securities covered by such registration
statement whenever the holder of such securities shall desire to sell or
otherwise dispose of the same (including prospectus supplements with respect to
the sales of securities from time to time in connection with a registration
statement pursuant to Rule 415 promulgated under the Act);

                (b) furnish to each Holder such numbers of copies of a summary
prospectus or other prospectus, including a preliminary prospectus or any
amendment or supplement to any prospectus, in conformity with the requirements
of the Act, and such other documents, as such Holder may reasonably request in
order to facilitate the public sale or other disposition of the securities owned
by such Holder;

                (c) use its best effort to register and qualify the securities
covered by the Amendment and Registration Statement under such other securities
or blue sky laws of such jurisdictions as the Holders shall reasonably request,
and do any and all other acts and things which may be necessary or advisable to
enable each Holder to consummate the public sale or other disposition in such
jurisdiction of the securities owned by such Holder, except that the Company
shall not for any such purpose be required to qualify to do business as a
foreign corporation in any jurisdiction wherein it is not so qualified or to
file therein any general consent to service of process;

                                       3
<PAGE>

                (d) list such securities on the NASDAQ Small Cap Stock Market or
other national securities exchange on which any securities of the Company are
then listed, if the listing of such securities is then permitted under the rules
of such exchange or NASDAQ;

                (e) enter into and perform its obligations under an underwriting
agreement, if the offering is an underwritten offering, in usual and customary
form, with the managing underwriter or underwriters of such underwritten
offering;

                (f) notify each holder of Registrable Securities covered by the
Registration Statement and GGR and the holder of the shares of Common Stock
underlying the Warrants issued to the Purchasers on the Subscription Date, at
any time when a prospectus relating thereto covered by the Amendment or the
Registration Statement is required to be delivered under the Act, of the
happening of any event of which it has knowledge as a result of which the
prospectus included in the Amendment or Registration Statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

           Section 6. Information by Holder. Each holder of Registrable
Securities, GGR Shares and the shares of Common Stock underlying the Warrants
issued to the Purchasers on the Subscription Date, included in any registration
shall furnish to the Company such information regarding such holder and the
distribution proposed by such holder as the Company may request in writing and
as shall be required in connection with any registration, qualification or
compliance referred to in this Section 6.

           Section 7. Assignment. The rights granted the Holders under this
Agreement shall not be assigned without the written consent of the Company,
which consent shall not be unreasonably withheld. This Agreement is binding upon
and inures to the benefit of the parties hereto and their respective heirs,
successors and permitted assigns.

           Section 8. Termination of Registration Rights. The rights granted
pursuant to this Agreement shall terminate as to each Holder (and permitted
transferee under Section 7 above) upon the occurrence of any of the following:

                (a) all such Holder's securities subject to this Agreement
have been registered;

                (b) all of such Holder's securities subject to this Agreement
may be sold without such registration pursuant to Rule 144 promulgated by the
SEC pursuant to the Securities Act;

                (c) all of such Holder's securities subject to this Agreement
can be sold pursuant to Rule 144(k); or

                (d) five and one half years from the issuance of the
Registrable Securities, GGR Shares, and the shares of Common Stock underlying
the Warrants issued to the Purchasers on the Subscription Date.

           Section 9.  Indemnification.

                (a) In the event of the filing of any Registration Statement
with respect to Registrable Securities, or any Amendment with respect to the GGR
Shares and the shares of Common Stock underlying the Warrants issued to the
Purchasers on the Subscription Date pursuant to Section 3 hereof, the Company
agrees to indemnify and hold harmless the Holders and each officer, director of
the Holders, and each person, if any, who controls the Holders within the
meaning of the Securities Act ("Distributing Holders") against any losses,
claims, damages or liabilities, joint or several (which shall, for all purposes
of this Agreement, include, but not be limited to, all costs of defense and
investigation and all attorneys' fees), to which the Distributing Holders may
become subject, under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or

                                       4
<PAGE>

are based upon any untrue statement or alleged untrue statement of any material
fact contained in any such Registration Statement, or any related preliminary
prospectus, final prospectus, offering circular, notification or amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; provided, however, that
the Company will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
such Registration Statement, preliminary prospectus, final prospectus, offering
circular, notification or amendment or supplement thereto in reliance upon, and
in conformity with, written information furnished to the Company by the
Distributing Holders, specifically for use in the preparation thereof. This
indemnity agreement will be in addition to any liability which the Company may
otherwise have.

                (b) Each Distributing Holder agrees that it will indemnify and
hold harmless the Company, and each officer, director of the Company or person,
if any, who controls the Company within the meaning of the Securities Act,
against any losses, claims, damages or liabilities (which shall, for all
purposes of this Agreement, include, but not be limited to, all costs of defense
and investigation and all attorneys' fees) to which the Company or any such
officer, director or controlling person may become subject under the Securities
Act or otherwise, insofar as such losses claims, damages or liabilities (or
actions in respect thereof; arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in a Registration
Statement requested by such Distributing Holder, or any related preliminary
prospectus, final prospectus, offering circular, notification or amendment or
supplement thereto, or arise out of or are based upon the omission or the
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, but in each case
only to the extent that such untrue statement or alleged untrue statement or
omission or alleged omission was made in such Registration Statement,
preliminary prospectus, final prospectus, offering circular, notification or
amendment or supplement thereto in reliance upon, and in conformity with,
written information furnished to the Company by such Distributing Holder,
specifically for use in the preparation thereof and, provided further, that the
indemnity agreement contained in this Section 9(b) shall not inure to the
benefit of the Company with respect to any person asserting such loss, claim,
damage or liability who purchased the Registrable Securities which are the
subject thereof if the Company failed to send or give (in violation of the
Securities Act or the rules and regulations promulgated thereunder) a copy of
the prospectus contained in such Registration Statement to such person at or
prior to the written confirmation to such person of the sale of such Registrable
Securities, where the Company was obligated to do so under the Securities Act or
the rules and regulations promulgated thereunder. This indemnity agreement will
be in addition to any liability which the Distributing Holders may otherwise
have.

                (c) Promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section, notify the indemnifying party of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve the
indemnifying party from any liability which it may have to any indemnified party
otherwise than as to the particular item as to which indemnification is then
being sought solely pursuant to this Section. In case any such action is brought
against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate in,
and, to the extent that it may wish, jointly with any other indemnifying party
similarly notified, assume the defense thereof, subject to the provisions herein
stated and after notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof, the indemnifying party will not
be liable to such indemnified party under this Section for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation, unless the
indemnifying party shall not pursue the action to its final conclusion. The
indemnified party shall have the right to employ separate counsel in any such
action and to participate in the defense thereof, but the fees and expenses of
such counsel shall not be at the expense of the indemnifying party if the
indemnifying party has assumed the defense of the action with counsel reasonably
satisfactory to the indemnified party; provided that if the indemnified party is
the Distributing Holder, the fees and expenses of such counsel shall be at the
expense of the indemnifying party if (i) the employment of such counsel has been
specifically authorized in writing by the indemnifying party, or (ii) the named
parties to any such action (including any impleaded parties) include both the
Distributing Holder and the indemnifying party and the Distributing Holder shall
have been advised by such counsel that there may be one or more legal defenses

                                       5
<PAGE>

available to the indemnifying party different from or in conflict with any legal
defenses which may be available to the Distributing Holder (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the Distributing Holder, it being understood, however, that the
indemnifying party shall, in connection with any one such action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable only for the reasonable
fees and expenses of one separate firm of attorneys for the Distributing Holder,
which firm shall be designated in writing by the Distributing Holder). No
settlement of any action against an indemnified party shall be made without the
prior written consent of the indemnified party, which consent shall not be
unreasonably withheld.

           Section 10. Contribution. In order to provide for just and equitable
contribution under the Securities Act in any case in which (i) the Distributing
Holder makes a claim for indemnification pursuant to Section 9 hereof but is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 9 hereof provide
for indemnification in such case, or (ii) contribution under the Securities Act
may be required on the part of any Distributing Holder, then the Company and the
applicable Distributing Holder shall contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (which shall, for all
purposes of this Agreement, include, but not be limited to, all costs of defense
and investigation and all attorneys' fees), in either such case (after
contribution from others) on the basis of relative fault as well as any other
relevant equitable considerations. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or the applicable
Distributing Holder, on the other hand, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Distributing Holder agree that it
would not be just and equitable if contribution pursuant to this Section were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in this
Section. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages or liabilities (or actions in respect thereof) referred
to above in this Section shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

           Section 11. Notices. Any notice pursuant to this Agreement by the
Company or by the Holders shall be in writing and shall be deemed to have been
duly given if delivered by (i) hand, (ii) by facsimile and followed by mail
delivery or (iii) if mailed by certified mail, return receipt requested, postage
prepaid, addressed as follows:

                (a) If to the Holders, to its, his or her address set forth on
the signature page of this Agreement, with a copy to the person designated in
the Agreement.

                (b) If to the Company, at the address set forth herein, or to
such other address as any such party may designate by notice to the other party.
Notices shall be deemed given at the time they are delivered personally or five
(5) days after they are mailed in the manner set forth above. If notice is
delivered by facsimile to the Company and followed by mail, delivery shall be
deemed given two (2) days after such facsimile is sent.

"Exercise Price") under this Warrant shall be equal to $1.00. The Exercise Price
and the number of shares for which the Warrant is exercisable shall be subject
to adjustment as provided herein. This Warrant is being issued in connection
with the Private Equity Line of Credit Agreement dated as of October , 1998, in
the aggregate amount of Fifteen Million ($15,000,000) Dollars (the "Agreement")
between the Company and Investor and is subject to its terms. In the event of
any conflict between the terms of this Warrant and the Agreement, the Agreement
shall control.

           1. Title of Warrant. Prior to the expiration hereof and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
holder hereof in person or by duly authorized attorney, upon surrender of this
Warrant together with the Assignment Form annexed hereto properly endorsed.

           2. Authorization of Shares. The Company covenants that all shares of
Common Stock which may be issued upon the exercise of rights represented by this
Warrant will, upon exercise of the rights represented by this Warrant, be duly
authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges in respect of the issue thereof (other than taxes in
respect of any transfer occurring contemporaneously with such issue).

           3. Exercise of Warrant. Exercise of the purchase rights represented
by this Warrant may be made at any time or times, in whole or in part, after the
Exercise Commencement Date and before the close of business on the Termination
Date, or such earlier date on which this Warrant may terminate as provided in

annexed hereto duly executed, at the office of the Company (or such other office
or agency of the Company as it may designate by notice in writing to the

the Company) and upon payment of the Exercise Price of the shares thereby
purchased; whereupon the holder of this Warrant shall be entitled to receive a

for shares purchased hereunder shall be delivered to the holder hereof within
five business days after the date on which this Warrant shall have been

representing fractional shares shall be issued upon the exercise of this
Warrant.

           5. Charges, Taxes and Expenses. Issuance of certificates for shares
of Common Stock upon the exercise of this Warrant shall be made without charge

in respect of the issuance of such certificate, all of which taxes and expenses
shall be paid by the Company, and such certificates shall be issued in the name
of the holder of this Warrant or in such name or names as may be directed by the
holder of this Warrant; provided, however, that in the event certificates for
shares of Common Stock are to be issued in a name other than the name of the
holder of this Warrant, this Warrant when surrendered for exercise shall be
accompanied by the Assignment Form attached hereto duly executed by the holder
hereof; and provided further, that upon any transfer involved in the issuance or
delivery of any certificates for shares of Common Stock, the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

           6. Closing of Books. The Company will at no time close its
shareholder books or records in any manner which interferes with the timely
exercise of this Warrant.

           7. No Rights as Shareholder until Exercise. This Warrant does not
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company prior to the exercise thereof. If, however, at the time of the
surrender of this Warrant and purchase the holder hereof shall be entitled to
exercise this Warrant, the shares so purchased shall be and be deemed to be
issued to such holder as the record owner of such shares as of the close of
business on the date on which this Warrant shall have been exercised.

           8. Assignment and Transfer of Warrant. This Warrant may be assigned
by the surrender of this Warrant and the Assignment Form annexed hereto duly
executed at the office of the Company (or such other office or agency of the
Company as it may designate by notice in writing to the registered holder hereof
at the address of such holder appearing on the books of the Company); provided,
however, that this Warrant may not be resold or otherwise transferred except (i)
in a transaction registered under the Securities Act, or (ii) in a transaction
pursuant to an exemption, if available, from such registration

           9. Loss, Theft, Destruction or Mutilation of Warrant. The Company
represents and warrants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of any Warrant
or stock certificate, and in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, and upon reimbursement to the Company of
all reasonable expenses incidental thereto, and upon surrender and cancellation
of such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of this Warrant or stock certificate.

           10. Saturdays, Sundays, Holidays, etc. If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a legal
holiday.

           11.  Effect of Certain Events.

           (a) If at any time the Company proposes (i) to sell or otherwise
convey all or substantially all of its assets or (ii) to effect a transaction
(by merger or otherwise) in which more than 50% of the voting power of the
Company is disposed of (collectively, a "Sale or Merger Transaction"), in which
the consideration to be received by the Company or its shareholders consists
solely of cash, the Company shall give the holder of this Warrant thirty (30)
days' notice of the proposed effective date of the transaction specifying that
the Warrant shall terminate if the Warrant has not been exercised by the
effective date of the transaction.

           (b) In case the Company shall at any time effect a Sale or Merger
Transaction in which the consideration to be received by the Company or its
shareholders consists in part of consideration other than cash, the holder of
this Warrant shall have the right thereafter to purchase, by exercise of this
Warrant and payment of the aggregate Exercise Price in effect immediately prior

                                       2
<PAGE>

to such action, the kind and amount of shares and other securities and property
which it would have owned or have been entitled to receive after the happening
of such transaction had this Warrant been exercised immediately prior thereto.

           (c) Registration. The Company agrees to register the shares of Common
Stock underlying this Warrant pursuant to the terms of the Agreement and the
Registration Rights Agreement dated October _____, 1998. In addition to the
foregoing, the Holder of this Warrant shall have the right to include all of the
shares of Common Stock underlying this Warrant (the "Registrable Securities") as
part of any registration of securities filed by the Company (other than in
connection with a transaction contemplated by Rule 145(a) promulgated under the
Act or pursuant to Form S-8) and must be notified in writing of such filing.
Holder shall have five (5) business days to notify the Company in writing as to
whether the Company is to include Holder or not include Holder as part of the
registration; provided, however, that if any registration pursuant to this
Section shall be underwritten, in whole or in part, the Company may require that
the Registrable Securities requested for inclusion pursuant to this Section be
included in the underwriting on the same terms and conditions as the securities
otherwise being sold through the underwriters. If in the good faith judgment of
the underwriter evidenced in writing of such offering only a limited number of
Registrable Securities should be included in such offering, or no such shares
should be included, the Holder, and all other selling stockholders, shall be
limited to registering such proportion of their respective shares as shall equal
the proportion that the number of shares of selling stockholders permitted to be
registered by the underwriter in such offering bears to the total number of all
shares then held by all selling stockholders desiring to participate in such
offering. Those Registrable Securities which are excluded from an underwritten
offering pursuant to the foregoing provisions of this Section (and all other
Registrable Securities held by the selling stockholders) shall be withheld from
the market by the Holders thereof for a period, not to exceed one hundred eighty
(180) days, which the underwriter may reasonably determine is necessary in order
to effect such underwritten offering.

           12. Adjustments of Exercise Price and Number of Warrant Shares. The
number and kind of securities purchasable upon the exercise of this Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
happening of any of the following.

           In case the Company shall (i) declare or pay a dividend in shares of
Common Stock or make a distribution in shares of Common Stock to holders of its
outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock,
(iii) combine its outstanding shares of Common Stock into a smaller number of
shares of Common Stock or (iv) issue any shares of its capital stock in a
reclassification of the Common Stock, the number of Warrant Shares purchasable
upon exercise of this Warrant immediately prior thereto shall be adjusted so
that the holder of this Warrant shall be entitled to receive the kind and number
of Warrant Shares or other securities of the Company which he would have owned
or have been entitled to receive had such Warrant been exercised in advance
thereof. An adjustment made pursuant to this paragraph shall become effective
immediately after the effective date of such event retroactive to the record
date, if any, for such event.

           13. Voluntary Adjustment by the Company. The Company may at its
warrant, at any time during the term of this Warrant, reduce the then current
Exchange Price to any amount and for any period of time deemed appropriate by
the Board of Directors of the Company.

           14. Notice of Adjustment. Whenever the number of Warrant shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested,
to the holder of this Warrant notice of such adjustment or adjustments setting
forth the number of Warrant Shares (and other securities or property)
purchasable upon the exercise of this Warrant and the Exercise Price of such
Warrant Shares after such adjustment, setting forth a brief statement of the
facts requiring such adjustment and setting forth computation by which such
adjustment was made. Such notice, in absence of manifest error, shall be
conclusive evidence of the correctness of such adjustment.

           15. Authorized Shares. The Company covenants that during the period
the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares to provide for the issuance of Common

                                       3
<PAGE>

Stock upon the exercise of any purchase rights under this Warrant. The Company
further covenants that its issuance of this Warrant shall constitute full
authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for shares of the
Company's Common Stock upon the exercise of the purchase rights under this
Warrant. The Company will take all such reasonable action as may be necessary to
assure that such shares of Common Stock may be issued as provided herein without
violation of any applicable law or regulation, or of any requirements of the OTC
Bulletin Board or any domestic securities exchange upon which the Common Stock
may be listed.

           16. Call. The Company has the right to "call" any portion of this
Warrant for exercise, for any portion of this Warrant which has not been then
exercised, by sending written notice to the holder, upon the satisfaction of the
following conditions: (i) closing bid price of the Common Stock (as reported by
Bloomberg, L.P.) is at least $1.50 per share for twenty (20) consecutive trading
days, and (ii) the registration statement filed by the Company covering the
shares of Common Stock underlying this Warrant has been declared effective by
the Securities and Exchange Commission, and must remain in effect at the time of
the call by the Company.

           17.  Miscellaneous.

           (a) Issue Date; Jurisdiction. The provisions of this Warrant shall be
construed and shall be given effect in all respects as if it had been issued and
delivered by the Company on the date hereof. This Warrant shall be binding upon
any successors or assigns of the Company. This Warrant shall constitute a
contract under the laws of Florida and for all purposes shall be construed in
accordance with and governed by the laws of said state without regard to its
conflict of law, principles or rules. The party who initiates legal action shall
choose the jurisdiction of the federal courts in connection with any dispute
arising under this Warrant and hereby waives, to the maximum permitted by law,
any objection, including any objection based on forum non conveniens, to the
bringing of any such proceeding in such jurisdictions. Each party waives its
right to a trial by jury.

           (b) Restrictions. The holder hereof acknowledges that the Common
Stock acquired upon the exercise of this Warrant, if not registered, may have
restrictions upon its resale imposed by state and federal securities laws.

           (c) Modification and Waiver. This Warrant and any provisions hereof
may be changed, waived, discharged or terminated only by an instrument in
writing signed by the party against which enforcement of the same is sought.

           (d) Notices. Any notice, request or other document required or
permitted to be given or delivered to the holders hereof of the Company shall be
delivered or shall be sent by certified or registered mail, postage prepaid, to
each such holder at its address as shown on the books of the Company or to the
Company at the address set forth in the Agreement.

business on the date on which this Warrant shall have been exercised.

           8. Assignment and Transfer of Warrant. This Warrant may be assigned
by the surrender of this Warrant and the Assignment Form annexed hereto duly
executed at the office of the Company (or such other office or agency of the
Company as it may designate by notice in writing to the registered holder hereof
at the address of such holder appearing on the books of the Company); provided,
however, that this Warrant may not be resold or otherwise transferred except (i)
in a transaction registered under the Securities Act, or (ii) in a transaction
pursuant to an exemption, if available, from such registration

           9. Loss, Theft, Destruction or Mutilation of Warrant. The Company
represents and warrants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of any Warrant
or stock certificate, and in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, and upon reimbursement to the Company of
all reasonable expenses incidental thereto, and upon surrender and cancellation
of such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of this Warrant or stock certificate.

           10. Saturdays, Sundays, Holidays, etc. If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a legal
holiday.

           11.  Effect of Certain Events.

           (a) If at any time the Company proposes (i) to sell or otherwise
convey all or substantially all of its assets or (ii) to effect a transaction
(by merger or otherwise) in which more than 50% of the voting power of the
Company is disposed of (collectively, a "Sale or Merger Transaction"), in which
the consideration to be received by the Company or its shareholders consists
solely of cash, the Company shall give the holder of this Warrant thirty (30)
days' notice of the proposed effective date of the transaction specifying that
the Warrant shall terminate if the Warrant has not been exercised by the
effective date of the transaction.

           (b) In case the Company shall at any time effect a Sale or Merger
Transaction in which the consideration to be received by the Company or its
shareholders consists in part of consideration other than cash, the holder of
this Warrant shall have the right thereafter to purchase, by exercise of this
Warrant and payment of the aggregate Exercise Price in effect immediately prior
to such action, the kind and amount of shares and other securities and property
which it would have owned or have been entitled to receive after the happening
of such transaction had this Warrant been exercised immediately prior thereto.

           (c) Registration. The Company agrees to register the shares of Common
Stock underlying this Warrant pursuant to the terms of the Agreement and the
Registration Rights Agreement dated October ____, 1998. In addition to the
foregoing, the Holder of this Warrant shall have the right to include all of the
shares of Common Stock underlying this Warrant (the "Registrable Securities") as
part of any registration of securities filed by the Company (other than in

                                       3
<PAGE>

connection with a transaction contemplated by Rule 145(a) promulgated under the
Act or pursuant to Form S-8) and must be notified in writing of such filing.
Holder shall have five (5) business days to notify the Company in writing as to
whether the Company is to include Holder or not include Holder as part of the
registration; provided, however, that if any registration pursuant to this
Section shall be underwritten, in whole or in part, the Company may require that
the Registrable Securities requested for inclusion pursuant to this Section be
included in the underwriting on the same terms and conditions as the securities
otherwise being sold through the underwriters. If in the good faith judgment of
the underwriter evidenced in writing of such offering only a limited number of
Registrable Securities should be included in such offering, or no such shares
should be included, the Holder, and all other selling stockholders, shall be
limited to registering such proportion of their respective shares as shall equal
the proportion that the number of shares of selling stockholders permitted to be
registered by the underwriter in such offering bears to the total number of all
shares then held by all selling stockholders desiring to participate in such
offering. Those Registrable Securities which are excluded from an underwritten
offering pursuant to the foregoing provisions of this Section (and all other
Registrable Securities held by the selling stockholders) shall be withheld from
the market by the Holders thereof for a period, not to exceed one hundred eighty
(180) days, which the underwriter may reasonably determine is necessary in order
to effect such underwritten offering.

           12. Adjustments of Exercise Price and Number of Warrant Shares. The
number and kind of securities purchasable upon the exercise of this Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
happening of any of the following.

           In case the Company shall (i) declare or pay a dividend in shares of
Common Stock or make a distribution in shares of Common Stock to holders of its
outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock,
(iii) combine its outstanding shares of Common Stock into a smaller number of
shares of Common Stock or (iv) issue any shares of its capital stock in a
reclassification of the Common Stock, the number of Warrant Shares purchasable
upon exercise of this Warrant immediately prior thereto shall be adjusted so
that the holder of this Warrant shall be entitled to receive the kind and number
of Warrant Shares or other securities of the Company which he would have owned
or have been entitled to receive had such Warrant been exercised in advance
thereof. An adjustment made pursuant to this paragraph shall become effective
immediately after the effective date of such event retroactive to the record
date, if any, for such event.


                                       4
<PAGE>


           13. Voluntary Adjustment by the Company. The Company may at its
warrant, at any time during the term of this Warrant, reduce the then current
Exchange Price to any amount and for any period of time deemed appropriate by
the Board of Directors of the Company.

           14. Notice of Adjustment. Whenever the number of Warrant shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested,
to the holder of this Warrant notice of such adjustment or adjustments setting
forth the number of Warrant Shares (and other securities or property)
purchasable upon the exercise of this Warrant and the Exercise Price of such
Warrant Shares after such adjustment, setting forth a brief statement of the
facts requiring such adjustment and setting forth computation by which such
adjustment was made. Such notice, in absence of manifest error, shall be
conclusive evidence of the correctness of such adjustment.

           15. Authorized Shares. The Company covenants that during the period
the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares to provide for the issuance of Common
Stock upon the exercise of any purchase rights under this Warrant. The Company
further covenants that its issuance of this Warrant shall constitute full
authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for shares of the
Company's Common Stock upon the exercise of the purchase rights under this
Warrant. The Company will take all such reasonable action as may be necessary to
assure that such shares of Common Stock may be issued as provided herein without
violation of any applicable law or regulation, or of any requirements of the OTC
Bulletin Board or any domestic securities exchange upon which the Common Stock
may be listed.

           16. Call. The Company has the right to "call" any portion of this
Warrant for exercise, for any portion of this Warrant which has not been then
exercised, by sending written notice to the holder, upon the satisfaction of the
following conditions: (i) closing bid price of the Common Stock (as reported by
Bloomberg, L.P.) is at least $2.25 per share for twenty (20) consecutive trading
days, and (ii) the registration statement filed by the Company covering the
shares of Common Stock underlying this Warrant has been declared effective by
the Securities and Exchange Commission, and must remain in effect at the time of
the call by the Company.

           17.  Miscellaneous.

           (a) Issue Date; Jurisdiction. The provisions of this Warrant shall be
construed and shall be given effect in all respects as if it had been issued and
delivered by the Company on the date hereof. This Warrant shall be binding upon
any successors or assigns of the Company. This Warrant shall constitute a
contract under the laws of Florida and for all purposes shall be construed in
accordance with and governed by the laws of said state without regard to its
conflict of law, principles or rules. The party who initiates legal action shall
choose the jurisdiction of the federal courts in connection with any dispute
arising under this Warrant and hereby waives, to the maximum permitted by law,
any objection, including any objection based on forum non conveniens, to the
bringing of any such proceeding in such jurisdictions. Each party waives its
right to a trial by jury.

           (b) Restrictions. The holder hereof acknowledges that the Common
Stock acquired upon the exercise of this Warrant, if not registered, may have
restrictions upon its resale imposed by state and federal securities laws.

           (c) Modification and Waiver. This Warrant and any provisions hereof
may be changed, waived, discharged or terminated only by an instrument in
writing signed by the party against which enforcement of the same is sought.

           (d) Notices. Any notice, request or other document required or
permitted to be given or delivered to the holders hereof of the Company shall be
delivered or shall be sent by certified or registered mail, postage prepaid, to
each such holder at its address as shown on the books of the Company or to the
Company at the address set forth in the Agreement.

                  3.4 This Agreement is the final expression of, and contains
the entire Agreement between, the parties with respect to the subject matter

Agreement may not be modified, changed, supplemented or terminated, nor may any

may enforce same by summary judgment in the courts of any country having
jurisdiction over the party against whom such judgment was obtained, and each
party hereby waives any defenses available to it under local law and agrees to
the enforcement of such a judgment. Each party to this Agreement irrevocably

                  3.8 This Agreement may be altered or amended only with the
written consent of all of the parties hereto. Should the Company, the Placement
Agent, or any Investor, attempt to change this Agreement in a manner which, in
the Escrow Agent's discretion, shall be undesirable, the Escrow Agent may resign
as Escrow Agent by notifying the Company and the Investors in writing. In the
case of the Escrow Agent's resignation or removal pursuant to the foregoing, its
only duty, until receipt of notice from the Company and the Investors or its
agent that a successor escrow agent shall have been appointed, shall be to hold
and preserve the funds. Upon receipt by the Escrow Agent of said notice from the
Company and the Investors of the appointment of a successor escrow agent, the
name of a successor escrow account and a direction to transfer the funds, the
Escrow Agent shall promptly thereafter transfer all of the funds held in escrow
to said successor escrow agent. Immediately after said transfer, the Escrow
Agent shall furnish the Company, the Placement Agent, and the Investors with
proof of such transfer. The Escrow Agent is authorized to disregard any notices,
requests, instructions or demands received by it from the Company, the Placement
Agent, or the Investors after notice of resignation or removal shall have been
given, unless the same shall be the aforementioned notice from the Company and
the Investors to transfer the funds to a successor escrow agent or to return
same to the respective parties.

                  3.9 The Escrow Agent shall be reimbursed by the Company and
the Investors for any reasonable expenses incurred in the event there is a
conflict between the parties and the Escrow Agent shall deem it necessary to
retain counsel.

                  3.10 The Escrow Agent shall not be liable for any action taken
or omitted by it in good faith in accordance with the advice of the Escrow
Agent's counsel; and in no event shall the Escrow Agent be liable or responsible
except for the Escrow Agent's own gross negligence or willful misconduct.

                           (iii) the Escrow Agent shall have no responsibility

                           or to file any financing statement under the Uniform

[Name and address of Transfer Agent]




Dear Sirs:

         Reference is made to the Private Equity Line of Credit Agreement and
all Exhibits and Attachments thereto (the "Agreement") dated as of October ___
1998, between entities listed on Schedule A (the "Investors") and Imaging
Diagnostic Systems, Inc. (the "Company"). Pursuant to the Agreement, subject to
the terms and conditions set forth in the Agreement the Investors have agreed to
purchase from the Company and the Company has agreed to sell to the Investors
from time to time during the term of the Agreement, and the Company has agreed
to issue to Settondown Capital International, Ltd. ("Settondown"), and
Goldstein, Goldstein & Reis, LLP ("GGR"), shares of common stock of the Company,
(the "Common Stock") and (ii) the Company has agreed to issue to the Investors
and the Settondown warrants to purchase Common Stock (the "Warrants"). As a
condition to the effectiveness of the Agreement, the Company has agreed to issue
to you, as the transfer agent for the Common Stock (the "Transfer Agent"), these
instructions relating to the Common Stock to be issued to the Investors,
Settondown and GGR (or their permitted assigns) pursuant to the Agreement or
upon exercise of the Warrants. All terms used herein and not otherwise defined
shall have the meaning set forth in the Agreement.

1.    ISSUANCE  OF COMMON STOCK WITHOUT THE LEGEND

         Pursuant to the Agreement, the Company is required to prepare and file
with the Commission, and maintain the effectiveness of, a registration statement
or registration statements registering the resale of the Common Stock to be
acquired by the Investors, Settondown and GGR, (i) under the Agreement and (ii)
upon exercise of the Warrants. The Company will advise the Transfer Agent in
writing of the effectiveness of any such registration statement promptly upon
its being declared effective. The Transfer Agent shall be entitled to rely on
such advice and shall assume that the effectiveness of such registration
statement remains in effect unless the Transfer Agent is otherwise advised in
writing by the Company and shall not be required to independently confirm the
continued effectiveness of such registration statement. In the circumstances set
forth in the following two paragraphs, the Transfer Agent shall deliver to the
Investors, Settondown and/or GGR, certificates representing Common Stock not
bearing the Legend without requiring further advice or instruction or additional
documentation from the Company or its counsel or the Investors, Settondown,
and/or GGR, or its their counsel or any other party (other than as described in
such paragraphs).

      At any time after the effective date of the applicable registration
statement (provided that the Company has not informed the Transfer Agent in
writing that such registration statement is not effective) upon any surrender of
one or more certificates evidencing Common Stock which bear the Legend, to the
extent accompanied by a notice requesting the issuance of new certificates free
of the Legend to replace those surrendered, the Transfer Agent shall deliver to
the Investors, Settondown and/or GGR, the certificates representing the Common
Stock not bearing the Legend, in such names and denominations as the Investors
shall request.

                                       1
<PAGE>

      In the event the Company files a Form S-3 registration statement and such
registration statement is declared effective by the Securities and Exchange
Commission in connection with any such event, the Investors, Settondown and/or
GGR, (or their permitted assigns) shall confirm in writing to the Transfer Agent
that (i) the Investors, Settondown and/or GGR, has sold, pledged or otherwise
transferred or agreed to sell, pledge or otherwise transfer such Common Stock in
a bona fide transaction to a third party that is not an affiliate of the
Company; and (ii) the Investors, Settondown and/or GGR, confirms to the transfer
agent that the Investors, Settondown and/or GGR, has complied with the
prospectus delivery requirement.

      In the event the Company files a registration statement other than on Form
S-3, which is subsequently declared effective by the Securities and Exchange
Commission, the Investors, Settondown and/or GGR, need not confirm the above in
writing to the Transfer Agent.

      In the event a registration statement is not filed by the Company, or for
any reason the registration statement which is filed by the Company is not
declared effective by the Securities and Exchange Commission the Investors,
Settondown and/or GGR, or their permitted assigns, or either of their brokers
confirms to the Transfer Agent that (i) the Investors, Settondown and/or GGR,
has held the shares of Common Stock for at least one year, (ii) counting the
shares surrendered as being sold upon the date the unlegended Certificates would
be delivered to the Investors, Settondown and/or GGR, (or the Trading Day
immediately following if such date is not a Trading Day), the Investors,
Settondown and/or GGR, will not have sold more than the greater of (a) one
percent (1%) of the total number of outstanding shares of Common Stock or (b)
the average weekly trading volume of the Common Stock for the preceding four
weeks during the three months ending upon such delivery date (or the Trading Day
immediately following if such date is not a Trading Day), and (iii) the
Investors, Settondown and/or GGR, has complied with the manner of sale and
notice requirements of Rule 144 under the Securities Act.

         Any advice, notice, or instructions to the Transfer Agent required or
permitted to be given hereunder may be transmitted via facsimile to the Transfer
Agent's facsimile number of (973) 239-2361.

2.    MECHANICS OF DELIVERY OF CERTIFICATES REPRESENTING COMMON STOCK

         In connection with any Closing pursuant to which the Investors,
Settondown and/or GGR, acquires Common Stock under the Agreement, the Transfer
Agent shall deliver to the Transfer Agent as defined in the Agreement
certificates representing Common Stock (with or without the Legend, as
appropriate) immediately.

3.    FEES OF TRANSFER AGENT; INDEMNIFICATION

         The Company agrees to pay the Transfer Agent for all fees incurred in
connection with these Irrevocable Instructions. The Company agrees to indemnify
the Transfer Agent and its officers, employees and agents, against any losses,
claims, damages or liabilities, joint or several, to which it or they become
subject based upon the performance by the Transfer Agent of its duties in
accordance with the Irrevocable Instructions.

4.    THIRD PARTY BENEFICIARY

         The Company and the Transfer Agent acknowledge and agree that the
Investors, Settondown and/or GGR, is an express third party beneficiary of these
Irrevocable Instructions and shall be entitled to rely upon, and enforce, the
provisions thereof.
