     (b) Exercise.

          (i) A Warrant Holder may exercise the Warrants, in whole or in part,

                                       3
<PAGE>

     to purchase the Underlying Shares in such amounts as may be elected upon
     surrender of the Warrant Certificate(s), together with duly executed
     Subscription Form(s), to the Company at its corporate office, together with
     the full Underlying Share Purchase Price for each Underlying Share to be
     purchased, in lawful money of the United States, or by certified check or
     bank draft payable in United States dollars to the order of the Company and
     upon compliance with and subject to the conditions set forth herein and in
     the Warrant Certificate(s).

          (ii) Upon receipt of such Warrant Certificate(s), together with the
     duly executed Subscription Form(s), and accompanied by payment of the
     Underlying Share Purchase Price for the number of Underlying Shares for
     which such Warrants are then being exercised, the Company shall, subject to
     Section 6(b) hereof, cause to be issued and delivered promptly, but in no
     event later than the third Business Day after the date on which the Company
     receives the Warrant Certificate(s), the Subscription Form(s) and the
     Underlying Share Purchase-Price, to the Warrant Holder certificates for
     such shares of Common Stock in such denominations as are requested by the
     Warrant Holder in the Subscription Form(s).

          (iii) In case a Warrant Holder shall exercise Warrants with respect to
     less than all of the Underlying Shares, the Company will execute new
     Warrant Certificate(s),substantially in the form attached hereto as Exhibit
     A, which shall be exercisable for the balance of the Underlying Shares that
     may be purchased upon exercise of the unexercised portion of the Warrants
     and shall deliver such new Warrant Certificate(s) to the Warrant Holder.
     Warrant Certificates shall be executed on behalf of the Company by the
     Company's Chairman of the Board, President or any Vice President and by its
     Treasurer, an Assistant Treasurer, its Secretary or an Assistant Secretary.

          (iv) Warrants shall be deemed to have been exercised immediately prior
     to the close of business on the Exercise Date, and the person entitled to
     receive the Underlying Shares and any Warrant Certificate(s) representing
     the unexercised portion of the Warrants deliverable upon such exercise
     shall be treated for all purposes as the holder of such Underlying Shares
     and unexercised Warrants, respectively, upon such exercise as of the close
     of business on the Exercise Date.

          (v) The Company covenants and agrees that it will pay when due and
     payable any and all taxes that may be payable in respect of the issue of
     the Warrants or the issue of any Underlying Shares. The Company shall not,
     however, be required to pay any tax that may be payable in respect of any
     transfer by the Warrant Holder of the Warrants or any Underlying Shares to
     any person or entity at the time of surrender. Until the payment of the tax
     referred to in the previous sentence and the presentation to the Company by
     the Warrant Holder of reasonable proof of such payment, the Company shall
     not be required to issue Underlying Shares or new Warrant Certificates
     representing unexercised Warrants to any transferee.

     (c) Cashless Exercise. In lieu of payment of the Underlying Share Purchase
Price, a Warrant Holder may exercise the Warrants, in whole or in part, by
presentation and surrender of Warrant Certificate(s) to the Company, together
with a duly executed Cashless Exercise Form (or a reasonable facsimile thereof)
(a "Cashless Exercise"). Acceptance by the Company of such

                                       4
<PAGE>

presentation and surrender shall be deemed a waiver of the Warrant Holder's
obligation to pay all or any portion of the Underlying Share Purchase Price in
cash, as the case may be. In the event of a Cashless Exercise, the Warrant
Holder shall exchange Warrants for that number of shares of Common Stock
determined by multiplying the number of shares of Common Stock for which the
Warrants are being exercised by a fraction, the numerator of which shall be the
difference between the then current market price per share of the Common Stock
and the Underlying Share Purchase Price, and the denominator of which shall be
the then current market price per share of Common Stock. For purposes of any
computation under this Section 2(c) or elsewhere in this Agreement, the then
current market price per share of Common Stock at any date shall be deemed to be
the average for the ten (10) consecutive Business Days immediately prior to the
date the Warrant Certificate(s) and Cashless Exercise Form is received by the
Company, or the date of any payment of cash for fractional shares pursuant to
Section 6(b) hereof, of the daily closing prices of the Common Stock on the
principal national securities exchange on which the Common Stock is admitted to
trading or listed or as reported by the NASDAQ National Market System, or if not
listed or admitted to trading on any such exchange or the NASDAQ National Market
System, the last reported sales prices as included for quotation on NASDAQ, or
if not included for quotation on NASDAQ, the average of the highest reported bid
and lowest reported asked prices in another over-the-counter market or if not
then publicly traded, the fair market price of the Common Stock as determined by
the Board of Directors of the Company.

     SECTION 3. Covenants.

     (a) Issuance and Sale of Underlying Shares. The Company covenants that it
will at all times reserve and keep available, free from preemptive rights, out
of its authorized Common Stock, solely for the purpose of issuance upon exercise
of the Warrants, such number of shares of Common Stock as shall equal the
aggregate number of the Underlying Shares. The Company covenants that all shares
of Common Stock that shall be issuable upon exercise of the Warrants shall, at
the time of delivery, and, subject to Section 2(c) hereof, upon receipt by the
Company of the Underlying Share Purchase Price, be duly and validly issued,
fully paid, nonassessable and free from all taxes, liens and charges with
respect to the issue thereof (other than those which the Company shall promptly
pay or discharge).

     The Transfer Agent for the Common Stock will be irrevocably authorized and
directed at all times to reserve such number of authorized shares of Common
Stock as shall be required for such purpose. The Company will keep a copy of
this Agreement on file with the Transfer Agent. The Company will supply such
Transfer Agent with duly executed certificates for such purposes and will
provide or otherwise make available any cash which may be payable as provided in
Section 6(b) hereof. The Company will furnish such Transfer Agent with a copy of
all notices of adjustments and certificates related thereto transmitted to the
Warrant Holder pursuant to Section 4(c) hereof.

     (b) SEC Reports. So long as the Warrants remain outstanding, the Company
shall cause copies of all of the information, documents, and other reports (or
copies of such portions of any of the foregoing as the SEC may by rules and
regulations prescribe) which the Company is required to file with the SEC
pursuant to Section 13 or 15(d) of the Exchange Act ("SEC

                                       5
<PAGE>

Reports") to be mailed to the Warrant Holder at his, her or its address
appearing in the register of warrant holders maintained by the Company, in each
case, within 15 days of filing with the SEC. If the Company is not subject to
the requirements of Section 13 or 15(d) of the Exchange Act, the Company shall
nevertheless continue to cause SEC Reports comparable to those which it would be
required to file pursuant to Section 13 or 15(d) of the Exchange Act if it were
subject to the requirements of either such section, to be so filed with the SEC
(but only if the SEC permits such filings) and mailed to the Warrant Holder, in
each case, within the same time periods as would have applied (including under
the preceding sentence) had the Company been subject to the requirements of
Section 13 or 15(d) of the Exchange Act.

     (c) Restrictive Legend. Each Warrant Certificate and certificate evidencing
shares of Common Stock issued to the Warrant Holder following the exercise of
Warrants shall bear the following restrictive legend until such time as the
transfer of such security is not restricted under the federal securities laws:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"),
          OR ANY STATE SECURITIES LAWS, AND MAY NOT BE OFFERED, SOLD, ASSIGNED,
          TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF EXCEPT
          PURSUANT TO (I) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT,
          (II) TO THE EXTENT APPLICABLE, RULE 144 UNDER THE ACT (OR ANY SIMILAR
          RULE UNDER SUCH ACT RELATING TO THE DISPOSITION OF SECURITIES), OR
          (III) AN OPINION OF COUNSEL, IF SUCH OPINION SHALL BE REASONABLY
          SATISFACTORY TO COUNSEL TO THE ISSUER, THAT AN EXEMPTION FROM
          REGISTRATION UNDER SUCH ACT IS AVAILABLE.

     SECTION 4. Adjustment of Underlying Share Purchase Price and Number of
Underlying Shares. The number of Underlying Shares purchasable upon the exercise
of the Warrants and the payment of the Underlying Share Purchase Price shall be
subject to adjustment from time to time as follows:

     (a) Dividends; Reclassifications, etc. In the event that the Company shall,
at any time prior to the earlier to occur of (i) the complete exercise of all
Warrants, and (ii) the Underlying Share Expiration Date: (A) declare or pay to
the holders of the Common Stock a dividend payable in any kind of shares of
capital stock of the Company; (B) change or divide or otherwise reclassify its
Common Stock into the same or a different number of shares with or without par
value, or in shares of any class or classes; (C) transfer its property as an
entirety or substantially as an entirety to any other company or entity; or (D)
make any distribution of its assets to holders of its Common Stock as a
liquidation or partial liquidation dividend or by way of return of capital;
then, upon the subsequent exercise of Warrants, the Warrant Holder shall
receive, in addition to or in substitution for the shares of Common Stock to
which he, she or it would

                                       6
<PAGE>

otherwise be entitled upon such exercise, such additional shares of stock or
scrip of the Company, or such reclassified shares of stock of the Company, or
such shares of the securities or property of the Company resulting from
transfer, or such assets of the Company, which he, she or it would have been
entitled to receive had he, she or it exercised the Warrants prior to the
happening of any of the foregoing events.

     (b) Reorganization of the Company. If the Company is a party to a merger or
other transaction which reclassifies or changes its outstanding Common Stock,
upon consummation of such transaction, the Warrants shall automatically become
exercisable into the kind and amount of securities, cash or other assets which
the Warrant Holder would have owned immediately alter such transaction if the
Warrant Holder had exercised the Warrants at the Underlying Share Purchase Price
in effect immediately before the effective date of the transaction. Concurrently
with the consummation of such transaction, the person obligated to issue
securities or deliver cash or other assets upon exercise of the Warrants shall
execute and deliver to the Warrant Holder new Warrants so providing and further
providing for adjustments which shall be as nearly equivalent as may be
practical to the adjustments provided in this Section 4(b). The successor
company also shall mail to the Warrant Holder a notice describing the new
Warrants.

     If securities deliverable upon exercise of Warrants, as provided above, are
themselves convertible into the securities of an affiliate of a corporation
formed, surviving or otherwise affected by the merger or other transaction, that
issuer shall join in the new Warrants which shall so provide. If this section
applies, Section 4(a) does not apply.

     (c) Sale of Common Stock Below the Underlying Share Purchase Price. (i) If,
after the date hereof, the Company shall (except as hereinafter provided) issue
any shares of Common Stock for a consideration less than the Underlying Share
Purchase Price then in effect, then the Underlying Share Purchase Price upon
each such issuance shall be adjusted to that price (calculated to the nearest
one cent) determined by multiplying the Underlying Share Purchase Price in
effect immediately prior to such event by a fraction:

          (A) the numerator of which shall be the number of shares of Common
     Stock outstanding immediately prior to the issuance of such additional
     shares of Common Stock plus the number of shares of Common Stock which the
     aggregate consideration for the total number of such additional shares of
     Common Stock so issued would purchase at the then effective Underlying
     Share Purchase Price, and

          (B) the denominator of which shall be the number of shares of Common
     Stock outstanding immediately prior to the issuance of such additional
     shares of Common Stock plus the number of such additional shares of Common
     Stock so issued.

     (ii) In addition to the adjustment to the Underlying Share Purchase Price
described in subsection (i) above, in the event the Company shall (except as
hereinafter provided) issue any shares of Common Stock for a consideration less
than the Underlying Share Purchase Price then in effect, then the number of
Underlying Shares purchasable upon the exercise of a Warrant shall be increased
to a number determined by multiplying the number of Underlying

                                       7
<PAGE>

Shares so purchasable immediately prior to the date of such issuance or sale by
a fraction, the numerator of which shall be the Underlying Share Purchase Price
in effect immediately prior to the adjustment required by subsection (i) above
and the denominator of which shall be the Underlying Share Purchase Price in
effect immediately after such adjustment.

     (iii) Anything in this Section 4(c) to the contrary notwithstanding, no
adjustment in the Underlying Share Purchase Price or the number of shares of
Common Stock purchasable upon the exercise of a Warrant shall be made in
connection with:

          (A) the grant, issuance or exercise of any Common Stock pursuant to
     the Company's qualified or non-qualified employee stock option plans or any
     other bona fide employee benefit plan or incentive arrangement, adopted or
     approved by the Company's Board of Directors or approved by the Company's
     shareholders, as they may be amended from time to time, or under any other
     bona fide employee benefit plan hereafter adopted by the Company's Board of
     Directors;

          (B) the grant, issuance or exercise of any Common Stock in connection
     with the hire or retention of any officer, director or key employee of the
     Company, provided such grant is approved by the Company's Board of
     Directors;

          (C) the issuance of any shares of Common Stock pursuant to the grant
     or exercise of convertible securities outstanding as of the date hereof; or

          (D) shares issued, subdivided or combined in transactions described in
     Section 4(a) if and to the extent that the number of shares of Common Stock
     received upon exercise of Warrants shall have been previously adjusted
     pursuant to Section 4(a) as a result of such issuance, subdivision or
     combination of such securities.

     (iv) For purposes of this Section 4(c), the following provisions shall also
be applied:

          (A) In the event of the issuance or sale of additional shares of
     Common Stock for cash, the consideration received by the Company therefor
     shall be deemed to be the amount of cash received by the Company for such
     shares, before deducting therefrom any commissions, compensation or other
     expenses paid or incurred by the Company for any underwriting of, or
     otherwise in connection with, the issuance or sale of such shares.

          (B) In the event of the issuance of shares of Common Stock for a
     consideration in whole or in part, other than cash, the consideration other
     than cash shall be deemed to be the current market price thereof as
     reasonably determined in good faith by the Board of Directors of the
     Company (irrespective of accounting treatment thereof); provided, however,
     that if such consideration consists of the cancellation of debt issued by
     the Company, the consideration shall be deemed to be the amount the Company
     received upon issuance of such debt (gross proceeds) plus accrued interest
     and, in the case of original issue discount or zero coupon indebtedness,
     accrued value to the date of such cancellation.

                                       8
<PAGE>

          (C) In the event of the issuance of additional shares of Common Stock
     upon the conversion or exchange of any obligations, the amount of the
     consideration received by the Company for such Common Stock shall be deemed
     to be the consideration received by the Company for such obligations or
     shares so converted or exchanged, before deducting from such consideration
     so received by the Company any expenses or commissions or compensation
     incurred or paid by the Company for any underwriting of, or otherwise in
     connection with, the issuance or sale of such obligations or shares, plus
     any consideration received by the Company in connection with such
     conversion or exchange. If obligations or shares of the same class or
     series of a class as the obligations or shares so converted or exchanged
     have been originally issued for different amounts of consideration, then
     the amount of consideration received by the Company upon the original
     issuance of each of the obligations or shares so converted or exchanged
     shall be deemed to be the average amount of the consideration received by
     the Company upon the original issuance of all such obligations or shares.

     (v) Anything in this Section 4(c) to the contrary notwithstanding, no
adjustment in the Underlying Share Purchase Price shall be required unless such
adjustment would require an increase or decrease of at least $0.15 in such
Underlying Share Purchase Price; provided, however, that any adjustments which
by reason of this subsection 4(c)(v) are not required to be made shall be
carried forward and taken into account in making subsequent adjustments.

     (d) Notice to Holder. If, at any time while Warrants remain outstanding,
the Company shall pay any dividend payable in cash or in Common Stock, shall
offer to the holders of its Common Stock for subscription or purchase by them
any shares of stock of any class or any other rights, shall enter into an
agreement to merge or consolidate with another corporation, shall propose any
capital reorganization or reclassification of the capital stock of the Company,
including any subdivision or combination of its outstanding shares of Common
Stock, or there shall be contemplated a voluntary or involuntary dissolution,
liquidation or winding up of the Company, the Company shall cause notice thereof
to be mailed to the registered Warrant Holder at his, her or its address
appearing on the registration books of the Company, at least 30 days prior to
the record date as of which holders of Common Stock shall participate in such
dividend, distribution or subscription or other rights or at least 30 days prior
to the effective date of the merger, consolidation, reorganization,
reclassification or dissolution.

     SECTION 5. Registration Rights.

     (a) Inclusion in Registration of Common Stock Issuable Upon Conversion of
Notes. The Warrant Holder shall have the right to include the Warrants and
Underlying Shares in the registration statement to be filed by the Company in
connection with the registration of the shares of Common Stock issuable upon
conversion of the Company's 8% Convertible Subordinated Promissory Notes due
December 31, 2004 (the "Registration Statement"). The Company shall provide
written notice to the Warrant Holder at least 5 Business Days prior to filing
the Registration Statement. If the Warrant Holder intends to include any
Registrable Securities in the Registration Statement, the Warrant Holder must
notify, in writing, the Company of its

                                       9
<PAGE>

intention to do so at least 2 Business Days prior to the date the Registration
Statement is to be filed with the SEC. The Company shall maintain the
effectiveness of the Registration Statement until such time as is the earlier of
(i) the date on which all Registrable Securities being registered thereunder
have been disposed of in accordance with the intended methods of disposition by
the seller or sellers thereof set forth in the Registration Statement, or (ii)
the date that is 2 years from the date the Warrants are issued hereunder.

     (b) Obligations of the Company. In connection with the registration of the
Registrable Securities as contemplated by Section 5(a), the Company shall:

          (i) prepare the Registration Statement and file it with the SEC, and
     thereafter use its reasonable best efforts to cause the Registration
     Statement to become effective, which Registration Statement (including any
     amendments or supplements thereto and prospectuses contained therein) shall
     not contain any untrue statement of a material fact or omit to state a
     material fact required to be stated therein, or necessary to make the
     statements therein, in light of the circumstances in which they were made,
     not misleading;

          (ii) prepare and file with the SEC such amendments (including
     post-effective amendments) and supplements to the Registration Statement
     and the prospectus used in connection with the registration statement as
     may be necessary to keep the Registration Statement effective and to comply
     with the provisions of the Securities Act with respect to the disposition
     of all Registrable Securities covered by the Registration Statement until
     such time as is the earlier of (A) the date on which all of such
     Registrable Securities have been disposed of in accordance with the
     intended methods of disposition by the seller or sellers thereof set forth
     in the Registration Statement, or (B) the date that is 2 years from the
     date the Warrants are issued hereunder;

          (iii) furnish to the Warrant Holder such number of copies of a
     prospectus, including a preliminary prospectus and all amendments and
     supplements thereto, and such other documents, as the Warrant Holder may
     reasonably request in order to facilitate the disposition of the
     Registrable Securities owned by the Warrant Holder;

          (iv) use reasonable efforts to (A) register and qualify the
     Registrable Securities covered by the Registration Statement under such
     other securities or Blue Sky laws of such jurisdictions reasonably
     requested by the Warrant Holder, (B) prepare and file in those
     jurisdictions all required amendments (including post-effective amendments)
     and supplements, (C) take such other actions as may be necessary to
     maintain such registrations and qualifications in effect at all times the
     Registration Statement is in effect, and (D) take all other actions
     necessary or advisable to enable the disposition of such securities in all
     such jurisdictions; provided, however, that the Company shall not be

     business in any jurisdiction where it would not otherwise be required to
     qualify but for this Section 5(b);

     underwriter of' such offering, in

                                       10
<PAGE>

     usual and customary form, including, without limitation, customary
     indemnification and contribution obligations, and (B) in the case of any
     non-underwritten offering, provide to broker-dealers participating in any
     distribution of Registrable Securities reasonable indemnification
     substantially similar to that provided by Section 5(e) hereof.

          (vi) promptly notify the Warrant Holder of the happening of any event
     of which the Company has knowledge, as a result of which the prospectus
     included in the 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,
     in light of the circumstances then existing, not misleading, and use its
     best efforts to prepare promptly a supplement or amendment to the
     Registration Statement to correct such untrue statement or omission, and
     deliver a number of copies of such supplement or amendment to the Warrant
     Holder as he, she or it may reasonably request;

          (vii) promptly notify the Warrant Holder (or, in the event of an

     withdrawal of any order suspending the effectiveness of the Registration
     Statement at the earliest possible time;

          (viii) permit counsel to the Warrant Holder to review the Registration

          (ix) make generally available to its security holders as soon as
     practical, but not later than 90 days alter the close of the period covered

     Rule 158 under the Securities Act) covering a twelve month period beginning
     not later than the first day of the Company's fiscal quarter next following
     the effective date of the Registration Statement;

          (x) at the request of the Warrant Holder, furnish on the date that
     Registrable Securities are delivered to an underwriter for sale in
     connection with the Registration Statement (A) a letter, dated such date,
     from the Company's independent certified public accountants, in form and
     substance as is customarily given by independent certified public
     accountants to underwriters in an underwritten public offering, addressed
     to the underwriters, and (B) an opinion, dated such date, from counsel
     representing the Company for purposes of such Registration Statement, in
     form and substance as is customarily given to underwriters in an
     underwritten public offering, addressed to the underwriters;

          (xi) make available for inspection by the Warrant Holder, any
     underwriter participating in any disposition pursuant to the Registration

     Warrant Holder or underwriter (collectively, the "Inspectors"), all
     pertinent financial and other records, pertinent corporate documents and
     properties of the Company, as shall be reasonably necessary to enable each
     Inspector to exercise

                                       11
<PAGE>

     its due diligence responsibility in connection with the preparation of the
     Registration Statement, and cause the Company's officers, directors and
     employees to supply all information reasonably requested by any such
     Inspector in connection with the Registration Statement;

          (xii) use its best efforts either to (A) cause all the Registrable
     Securities, except for the Warrants, covered by the Registration Statement
     to be listed on a national securities exchange and on each additional
     national securities exchange on which similar securities issued by the
     Company are then listed, if any, if the listing of such Registrable
     Securities is then permitted under the rules of such exchange or (B) secure
     designation of all the Registrable Securities, except the Warrants, covered
     by the Registration Statement as a NASDAQ "National Market Security" and
     the quotation of the Registrable Securities on the NASDAQ National Market;

          (xiii) provide a transfer agent and registrar, which may be a single
     entity, for the Registrable Securities not later than the effective date of
     the Registration Statement;

          (xiv) cooperate with the Warrant Holder and the managing underwriter
     or underwriters, if any, to facilitate the timely preparation and delivery
     of certificates (not bearing any restrictive legends) representing
     Registrable Securities to be sold pursuant to the Registration Statement
     and enable such certificates to be in such denominations or amounts, as the
     case may be, and registered in such names as the managing underwriter or
     underwriters, if any, or the Warrant Holder may reasonably request; and

          (xv) take all other reasonable actions necessary to expedite and
     facilitate disposition of Registrable Securities by the Warrant Holder
     pursuant to the Registration Statement.

     (c) Obligations of the Warrant Holder.

          (i) It shall be a condition precedent to the obligations of the
     Company to take any action pursuant to this Warrant with respect to the
     Warrant Holder that the Warrant Holder shall furnish to the Company such
     information regarding the Warrant Holder, the Registrable Securities held
     by the Warrant Holder and the intended method of disposition of such
     securities as shall be reasonably required to effect the registration of
     the Registrable Securities and shall execute such documents and agreements
     in connection with such registration as the Company may reasonably request.
     At least 5 Business Days prior to the first anticipated filing date of the
     Registration Statement, the Company shall notify the Warrant Holder of the
     information the Company requires from he, she or it (the "Requested
     Information") if he, she or it elects to have any of its Registrable
     Securities included in the Registration Statement. If within 3 Business
     Days of the filing date the Company has not received the Requested
     Information from the Warrant Holder, then the Company may file the
     Registration Statement without including Registrable Securities of the
     Warrant Holder.

          (ii) The Warrant Holder, by its, his or her acceptance of the
     Registrable Securities, agrees to cooperate with the Company in connection
     with the preparation and filing

                                       12
<PAGE>

     of any Registration Statement hereunder.

          (iii) In the event of an underwritten offering, the Warrant Holder
     agrees to enter into and perform its obligations under an underwriting
     agreement, in usual and customary form, including without limitation
     customary indemnification and contribution obligations, with the managing
     underwriter of such offering and to take such other actions as are
     reasonably required in order to expedite or facilitate the disposition of
     the Registrable Securities, unless the Warrant Holder has decided not to
     participate.

          (iv) The Warrant Holder agrees that, upon receipt of any notice from
     the Company of the happening of any event of the kind described in Section
     5(b)(vi), the Warrant Holder will immediately discontinue disposition of
     Registrable Securities pursuant to the Registration Statement covering such
     Registrable Securities until its, his or her receipt of the copies of the
     supplemented or amended prospectus contemplated by Section 5(b)(vi) and, if
     so directed by the Company, the Warrant Holder shall deliver to the Company
     (at the expense of the Company) or destroy (and deliver to the Company a
     certificate of such destruction) all copies, other than permanent file
     copies then in its, his or her possession, of the prospectus covering such
     Registrable Securities current at the time of receipt of such notice.

     (d) Expenses of Registration. In connection with any and all registrations
pursuant to Section 5, all expenses other than underwriting discounts and
commissions incurred in connection with registration, filings or qualifications,
including, without limitation, all registration, listing, filing and
qualification fees, printing and accounting fees and costs, the fees and
disbursements of counsel for the Company and the reasonable fees and
disbursements for one firm of counsel for the Warrant Holder shall be borne by
the Company.

     (e) Indemnification. In the event any Registrable Securities are included
in a Registration Statement under this Warrant:

          (i) To the extent permitted by law, the Company will indemnify and
     hold harmless the Warrant Holder (in such capacity) and its members,
     managers, directors, officers and/or agents, any underwriter (as defined in
     the Securities Act) for the Warrant Holder, and each person, if any, who
     controls any such underwriter within the meaning of Section 15 of the
     Securities Act (collectively, an "indemnified Party"), against any losses,
     claims, damages, expenses, liabilities (joint or several) (collectively,
     "Claims") to which any of them may become subject under the Securities Act,
     the Exchange Act or otherwise, insofar as such Claims (or actions or
     proceedings, whether commenced or threatened, in respect thereof) arise out
     of or are based upon any of the following statements, omissions or
     violations (collectively, a "Violation"); (A) any untrue statement or
     alleged untrue statement of a material fact contained in the Registration
     Statement or any post-effective amendment thereof, or 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, or (B)
     any untrue statement or alleged untrue statement of a material fact
     contained in any preliminary prospectus if used prior to the effective date
     of such Registration Statement, or contained in the final prospectus (as
     amended or supplemented if the Company files any amendment thereof or
     supplement thereto with the SEC), or the omission or

                                       13
<PAGE>

     alleged omission to state therein a material fact required to be stated
     therein, or necessary in order to make the statements therein, in light of
     the circumstances under which they were made, not misleading. Subject to
     the restrictions set forth in Section 5(e)(iv) with respect to the number
     of legal counsel, the Company shall promptly reimburse the Warrant Holder,
     and each such other person entitled to indemnification under this Section
     5(e)(i), as such expenses are incurred and are due and payable, for any
     legal fees or other reasonable expenses incurred by them in connection with
     investigating or defending any such Claim, whether or not such Claim,
     investigation or proceeding is brought or initiated by the Company or a
     third party. Notwithstanding anything to the contrary contained herein, the
     indemnification agreement contained in this Section 5(e)(i) shall not (A)
     apply to a Claim arising out of or based upon a Violation which occurs in
     reliance upon and in conformity with information furnished in writing to
     the Company by the Warrant Holder expressly for use in connection with the
     preparation of the Registration Statement, any prospectus or any such
     amendment thereof or supplement thereto or any failure of the Warrant
     Holder to deliver a prospectus as required by the Securities Act; or (B)
     apply to amounts paid in settlement of any Claim if such settlement is
     effected without the prior written consent of the Company, which consent
     shall not be unreasonably withheld. Such indemnity shall remain in full
     force and effect regardless of any investigation made by or on behalf of
     the Warrant Holder and shall survive the transfer of the Registrable
     Securities by the Warrant Holder as provided herein.

          (ii) In connection with any Registration Statement in which the
     Warrant Holder is participating in such capacity, the Warrant Holder agrees
     to indemnify and hold harmless, to the same extent and in the same manner
     set forth in Section 5(e)(i), the Company, each of its directors, each of
     its officers who sign the Registration Statement, each person, if any, who
     controls the Company within the meaning of the Securities Act, any
     underwriter and any other stockholder selling securities pursuant to the
     Registration Statement or any of its directors or officers or any person
     who controls such stockholder or underwriter (collectively, also an
     "Indemnified Party"), against any Claim to which any of them may become
     subject, under the Securities Act, the Exchange Act or otherwise, insofar
     as such Claim arises out of or is based upon any Violation, in each case to
     the extent (and only to the extent) that such Violation occurs in reliance
     upon and in conformity with written information famished to the Company by
     the Warrant Holder expressly for use in connection with such Registration
     Statement; and the Warrant Holder shall promptly reimburse an Indemnified
     Party, as such expenses are incurred and are due and payable, for any legal
     fees or other reasonable expenses incurred by the Indemnified Party in
     connection with investigating or defending any such Claim, whether or not
     such claim, investigation or proceeding is brought or initiated by the
     Indemnified Party or a third party; provided, however, that the indemnity
     agreement contained in this Section 5(e)(ii) shall not apply to amounts
     paid in settlement of any Claim if such settlement is effected without the
     prior written consent of the Warrant Holder, which consent shall not be
     unreasonably withheld; provided, further, that the Warrant Holder shall be
     liable under this Section 5(e)(ii) for only that amount of a Claim as does
     not exceed the net proceeds to it as a result of the sale of Registrable
     Securities pursuant to such Registration Statement.

          (iii) The Company shall be entitled to receive indemnification from
     underwriters, selling brokers, dealer managers, and similar securities
     industry professionals

                                       14
<PAGE>

     participating in the distribution to the same extent as provided above,
     with respect to information about such persons so furnished in writing by
     such persons expressly for inclusion in the Registration Statement.

          (iv) Promptly after receipt by an Indemnified Party under this Section
     5(e) of notice of the commencement of any action (including any
     governmental action), such Indemnified Party shall, if a Claim in respect
     thereof is to be made against any indemnifying party under this Section
     5(e), deliver to an indemnifying party a written notice of the commencement
     thereof, and the indemnifying party shall have the right to participate in,
     and, to the extent the indemnifying party so desires, jointly with any
     other indemnifying party similarly given notice, to assume control of the
     defense thereof with counsel satisfactory to the Indemnified Party;
     provided, however, that an Indemnified Party shall have the right to retain
     its, his or her own counsel, with the fees and expenses to be paid by the
     indemnifying party, if, in the reasonable opinion of counsel for such
     party, representation of such party by the counsel retained by the
     indemnifying party would be inappropriate due to actual or potential
     differing interests between such party and any other party represented by
     such counsel in such proceeding. The Company shall pay for only one legal
     counsel for the Warrant Holder and any Indemnified Party related thereto;
     such legal counsel shall be selected by the Warrant Holder or such other
     Indemnified Party subject to the Company's approval which shall not be
     unreasonably withheld. The failure to deliver written notice to the
     indemnifying party within a reasonable time of the commencement of any such
     action shall not relieve such indemnifying party of any liability to
     another under this Section 5(e), except to the extent that such failure to
     notify results in the forfeiture by the indemnifying party of substantive
     rights or defenses. The indemnification required by this Section 5(e) shall
     be made by periodic payments of the amount thereof during the course of the
     investigation or defense, as such expense, loss, damage or liability is
     incurred and is due and payable.

          (f) Contribution. To the extent any indemnification by an indemnifying
     party is prohibited or limited by law, the indemnifying party agrees to
     make the maximum contribution with respect to any amounts for which, he,
     she or it would otherwise be liable under Section 5(e) to the fullest
     extent permitted by law; provided, however, that (i) no contribution shall
     be made under circumstances where the maker would not have been liable for
     indemnification under Section 5(e), (ii) no seller of Registrable
     Securities guilty of fraudulent misrepresentation (within the meaning used
     in the Securities Act shall be entitled to contribution from any seller of
     Registrable Securities who was not guilty of such fraudulent
     misrepresentation, and (iii) contribution by any seller of Registrable
     Securities shall be limited in amount to the net amount of proceeds
     received by such seller from the sale of such Registrable Securities.

          (g) Reports Under Exchange Act. With a view to making available to the
     Warrant Holder the benefits of Rule 144 promulgated under the Securities
     Act or any other similar rule or regulation of the SEC that may at any time
     permit the security holders to sell securities of the Company to the public
     without registration ("Rule 144"), the Company shall at all times:

               (i) make and keep public information available, as those terms
          are understood and defined in Rule 144;

                                       15
<PAGE>

               (ii) file with the SEC in a timely manner all reports and other
          documents required of the Company under the Securities Act and the
          Exchange Act; and

               (iii) furnish to the Warrant Holder while a holder hereof,
          promptly upon request, (A) a written statement by the Company that it
          has complied with the reporting requirements of Rule 144, the
          Securities Act and the Exchange Act, (B) a copy of the most recent
          annual or quarterly report of the Company and such other reports and
          documents so filed with the SEC by the Company, and (C) such other
          information as may be reasonably requested to permit the Warrant
          Holder to sell such securities without registration.

     (h)

     SECTION 6. Other Provisions Relating to Rights of the Warrant Holder.

     (a) Warrant Holder not a Stockholder. The Warrant Holder, as such, shall
not be entitled to vote or receive dividends or be deemed holders of Common
Stock for any purpose whatsoever, nor shall anything contained in this Agreement
be construed to confer upon the Warrant Holder, as such, any of the rights of a
stockholder of the Company including, but not limited to, the right to vote for
the election of directors or on any other matter, give or withhold consent to
any action by the Company (whether upon any recapitalization, issue of stock,
reclassification of stock, consolidation, merger, conveyance or otherwise),
receive notice of meetings or other action affecting stockholders (except for
notices provided for in this Agreement), receive dividends or subscription
fights, or otherwise until Warrants shall have been exercised to purchase
Underlying Shares, at which time the person or persons in whose name or names
the certificate or certificates for the shares of Common Stock are registered
shall be deemed the holder or holders of record of such shares of Common Stock
for all purposes.

     (b) Fractional Shares. Anything contained herein to the contrary
notwithstanding, the Company shall not be required to issue any fractional
shares of Common Stock in connection with the exercise of the Warrants. In any
case where the Warrant Holder would, except for the provisions of this Section
6(b), be entitled under the terms of this Agreement to receive a fraction of a
share of Common Stock upon the exercise of the Warrants, the Company shall, upon
the exercise of the Warrants and receipt of the Underlying Share Purchase Price,
issue the largest number of whole shares of Common Stock purchasable upon
exercise of the Warrants. The Warrant Holder expressly waives his, her or its
right to receive a certificate of any fraction of a share of Common Stock upon
the exercise hereof. However, with respect to any fraction of a share of Common
Stock called for upon any exercise hereof, the Company shall pay to the Warrant
Holder an amount in cash equal to such fraction multiplied by the current market
price per share of Common Stock determined pursuant to Section 2(c) hereof.

     (c) Absolute Owner. Prior to due presentment for registration of transfer
of the Warrant Certificates, the Company may deem and treat the Warrant Holder
as the absolute owner of the Warrants for the purpose of any exercise thereof
and for all other purposes and the Company shall not be affected by any notice
to the contrary.

                                       16
<PAGE>

     SECTION 7. Division, Split-Up, Combination, Exchange and Transfer of
Warrants.

     (a) Request. The Warrants may be divided, split up, combined or exchanged
for other Warrants of like tenor to purchase a like aggregate number of
Underlying Shares. If the Warrant Holder desires to divide, split up, combine or
exchange the Warrants, he, she or it shall make such request in writing
delivered to the Company at its office in West Melbourne, Florida, or as
otherwise directed by the Company in writing, and shall surrender such Warrant
Certificates to be so divided, split up, combined or exchanged at said office.
Upon any such surrender for a division, split-up, combination or exchange, the
Company shall execute and deliver to the person or persons entitled thereto a
new Warrant Certificate(s) as so requested. The Company may require the Warrant
Holder to pay a sum sufficient to cover any tax, governmental or other charge
that may be imposed in connection with any division, split-up, combination or
exchange of the Warrants.

     (b) Initial Issuance to JMS. The Company shall issue the right to purchase
166,153 Underlying Shares to JMS, as represented by a Warrant Certificate issued
to JMS in the form attached hereto as Exhibit A or, subject to compliance with
the Act, to such officers, managers or employees of JMS as JMS may direct.

     (c) Assignment; Replacement of Warrant Certificates. The Warrants may be
sold, transferred, assigned or hypothecated by JMS at any time, in whole or in
part, subject to compliance with federal and state securities laws; provided,
however, that if the Warrants are not registered prior to any transfer,
assignment or hypothecation, JMS shall provide an opinion of counsel, which
opinion shall be reasonably satisfactory to counsel to the Company, that the
transfer, assignment or hypothecation qualifies for an exemption from
registration under the Act. Any division or assignment permitted of the Warrants
shall be made by surrender by the Warrant Holder of the Warrant Certificates to
the Company at its principal office with the Assignment Form attached as Exhibit
C hereto duly executed, together with funds sufficient to pay any transfer tax.
In such event, the Company shall, without charge, execute and deliver a new
Warrant Certificate in the name of the assignee named in such instrument of
assignment and the o surrendered Warrant Certificate(s) shall promptly be
canceled. Upon receipt by the Company of evidence satisfactory to it of the
loss, theft, destruction or mutilation of the Warrant Certificate(s) and (in the
case of loss, theft or destruction) of reasonably satisfactory indemnification,
and (in the case of mutilation) upon surrender and cancellation of such Warrant
Certificate(s), the Company will execute and deliver a new Warrant(s)
Certificate of like tenor and date and any such lost, stolen or destroyed
Warrant Certificate(s) shall thereupon become void.

     SECTION 8. Other Matters.

     (a) Taxes and Charges. The Company will from time to time promptly pay,
subject to the provisions of paragraph (v) of Section 2(b), all taxes and
charges that may be imposed upon the Company in respect of the issuance or
delivery, but not the transfer, of the Warrants or the Underlying Shares.
