          WHEREAS, On-Point Technology Systems, Inc., a Nevada corporation (the
     "Company") maintains the On-Point Technology Systems, Inc. 1994 Stock
     Option Plan (the "Plan") for the benefit of certain of its employees; and

          WHEREAS, prior to October 13, 2000, the Plan, as amended, permitted
     the issuance of options for 1,500,000 shares; and

     approved by the shareholders at a meeting held on December 8, 2000; and

          WHEREAS, between the date of the Proxy Statement and the date of the
     shareholders meeting, the Board of Directors of the Company approved a

     approval was being sought from 3,000,000 shares to 1,000,000 shares.

     NOW, THEREFORE, the premises considered, the Plan, as amended, is further
amended as follows:

                                   CONVERSION

          (a) RIGHT OF CONVERSION.

               (i) At any time after the Initial Conversion Date, as hereinafter
defined, the Holder shall have the right, in whole at any time and in part from
time to time, prior to payment of the principal of this Note, to convert all or
any part of the principal amount of this Note outstanding from time to time and,
subject to the provisions of Paragraph 3(f) of this Note, any accrued but unpaid
interest thereon into shares of the Company's common stock, par value $.01 per
share ("Common Stock"), at the conversion price hereinafter defined (the
"Conversion Price"); provided, that the right of conversion shall terminate at
5:00 P.M. San Diego, California time on the business day prior to the Maturity
Date of this Note; and provided, further, that if this Note shall be called for
prepayment as provided in Paragraph 6(a) of this Note, the right of conversion
shall terminate at 5:00 P.M., San Diego, California time on the business day
prior to the Prepayment Date, as defined in said Paragraph 6(a).

               (ii) In order to exercise the conversion right, the holder of
this Note shall surrender this Note at the office of the Company together with
written instructions specifying the portion of the principal amount of and,
subject to the provisions of Paragraph 3(f) of this Note, accrued interest on
this Note which the holder elects to convert and the registration and delivery
of certificates for shares of Common Stock issuable upon such conversion. The
shares of Common Stock issuable upon conversion of principal and interest on
this Note are referred to as the "Conversion Shares." The number of Conversion
Shares to be issued upon any whole or partial conversion of this Note shall be
determined by dividing the amount of principal and interest being converted by
the Conversion Price in effect on the date of such conversion, which shall be
the date this Note is delivered to the Company for conversion. The Holder shall
thereupon be deemed to be the holder of the number of shares of Common Stock so
issued, and the principal amount of the Note and interest thereon, to the extent
so converted, shall be deemed to have been paid in full. If this Note shall have
been converted in part, the Holder shall be entitled to a new Note representing
the unpaid principal balance of this Note remaining after deducting the
principal amount of the Note converted. Within five (5) days of any partial or
full conversion of this Note, the Company will instruct its transfer agent to
promptly issue the Conversion Shares to the Holder.

               (iii) The Initial Conversion Date shall mean the first date
following the date of this Note on which the certificate of incorporation of the
Company is amended to increase the number of authorized shares of Common Stock
if such amendment is filed prior to the Maturity Date of this Note.

          (b) CONVERSION PRICE.

               (i) The Conversion Price shall mean six dollars ($6.00) per
share; subject to adjustment as hereinafter provided in this Article 3.

               (ii) Notwithstanding the provisions of Paragraph 3(b)(i) of this
Note, in the event that the Company shall have failed to receive gross proceeds
of five million dollars ($5,000,000) from a Qualified Offering, as hereinafter
defined, during the Applicable Period, the Conversion Price shall be equal to
the lesser of (A) one and 50/100 dollars ($1.50) per share (subject to
adjustment in the manner provided in Paragraph 3(c) and (d) of this Note), or
(B) the lowest price (or, if convertible securities are sold, the lowest
conversion price) at which common stock is sold or the lowest conversion price
of convertible securities issued during such period (other than stock options
granted pursuant to a

                                     - 4 -
<PAGE>

stock option plan approved by the shareholders of the Company or the shares of
Common Stock issued upon conversion or exercise of convertible securities which
were outstanding on December 1, 2000). The Conversion Price determined pursuant
to this Paragraph 3(b)(ii) shall be subject to adjustment as hereinafter
provided in this Article 3. The Company shall be deemed to receive the proceeds
of a Qualified Offering by the last day of the Applicable Period if on such date
(x) the purchasers of securities pursuant to the Qualified Offering shall have
executed binding agreements to purchase the securities, (y) the Company shall
have complied with all of its obligations required to be performed by it prior
to payment of the purchase price of the securities, and (z) the purchasers are
in the process of making payment for the securities purchased in the Qualified
Offering.

               (iii) The Applicable Period shall mean the period commencing
December 1, 2000 and ending January 31, 2001; provided, however, that if, in
order to raise such five million dollars ($5,000,000), it is necessary for the
Company either to obtain shareholder approval or to obtain approval of the
Commission pursuant to the Securities Act or the Nasdaq Stock Market, then the
Company shall be entitled to a reasonable extension of last day of the
Applicable Period in order to obtain the approval of the shareholders, the
Commission or the Nasdaq Stock Market, as the case may be, as long as the
Company is in the process of obtaining such approvals on January 31, 2001 and is
on such date and thereafter actively seeking to obtain such approval.

               (iv) A Qualified Offering shall mean public or private sale by
the Company of its debt or equity securities at a price of not less than six
dollars ($6.00) per share, or, if convertible securities are issued, at a
conversion price of not less than six dollars ($6.00) per share, in one or more
offerings during the Applicable Period. The prices set forth in this Paragraph
3(b)(iv) shall be subject to adjustment in the manner provided in Paragraph 3(c)
and (d) of this Note.

               (v) Convertible securities shall mean convertible debt or equity
securities or notes, debentures or other evidences of indebtedness or warrants,
options or rights or any other securities upon the conversion or exercise of
which or pursuant to the terms of which shares of Common Stock or other
convertible securities may be issued. The conversion price with respect to any
convertible security shall be the price designated in the convertible security
as the conversion price, the exercise price, the purchase price or the other
applicable price at which common stock are issuable. If convertible securities
are issuable upon conversion of other convertible securities, the conversion
price shall mean the price determined by dividing (x) the sum of (A) the price
paid for the convertible security plus (B) any additional payment to be made on
exercise of the convertible security, by (y) the total number of shares of
Common Stock issued or issuable after all convertible securities, including
convertible securities issuable upon conversion of convertible securities, are
fully converted.

          (c) ADJUSTMENT IN CONVERSION PRICE. If the Company shall, subsequent
to December 1, 2000, (A) pay a dividend or make a distribution on its shares of
Common Stock in shares of Common Stock, (B) subdivide or reclassify its
outstanding Common Stock into a greater number of shares or otherwise effect a
stock split, or (C) combine or reclassify its outstanding Common Stock into a
smaller number of shares or otherwise effect a reverse split, the Conversion
Price in effect at the time of the record date for such dividend or distribution
or of the effective date of such subdivision or other combination or
reclassification shall be proportionately adjusted upward or downward, as the
case may be in accordance with generally accepted accounting principles. Such
adjustment shall be made successively whenever any event listed in this
Paragraph 3(c) shall occur.

          (d) RECLASSIFICATION, REORGANIZATION OR MERGER. In case of any
reclassification, capital reorganization or other change of outstanding shares
of Common Stock of the Company, or in case of any consolidation or merger of the
Company with or into another corporation (other than a merger with

                                     - 5 -
<PAGE>

a subsidiary in which merger the Company is the continuing corporation and which
does not result in any reclassification, capital reorganization or other change
of outstanding shares of Common Stock or the class issuable upon conversion of
this Note) or in case of any sale, lease or conveyance to another corporation of
the property of the Company as an entirety, the Company shall, as a condition
precedent to such transaction, cause effective provisions to be made so that the
Holder shall have the right thereafter by converting this Note, to purchase the
kind and amount of shares of stock and other securities and property receivable
upon such reclassification, capital reorganization and other change,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Common Stock which might have been purchased upon conversion of this Note
immediately prior to such reclassification, change, consolidation, merger, sale
or conveyance. Any such provision shall include provision for adjustments which
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Note. The foregoing provisions of this Paragraph 3(d) shall
similarly apply to successive reclassifications, capital reorganizations and
changes of shares of Common Stock and to successive consolidations, mergers,
sales or conveyances. In the event that in connection with any such capital
reorganization or reclassification, consolidation, merger, sale or conveyance,
additional shares of Common Stock shall be issued in exchange, conversion,
substitution or payment, in whole in part, for a security of the Company other
than Common Stock, such transaction shall be treated as a reclassification or
reorganization pursuant to this Paragraph 3(d).

          (e) FRACTIONAL SHARES. No fractional shares or script representing
fractional shares shall be issued upon the conversion of any Notes. If, upon any
full or partial conversion of this Note, the holder would, except for the
provisions of this Paragraph 3(e), be entitled to receive a fractional share of
Common Stock, then the Company shall at its election, either (i) round up the
number of shares of Common Stock issuable upon such conversion to the next
higher integral number of shares or (ii) pay the Holder, at the time the shares
of Common Stock are issued on such conversion, an amount equal to such
fractional share multiplied by the then current value per share of Common Stock,
determined as follows:

               (i) If the Common Stock is listed on a national securities
exchange or admitted to unlisted trading privileges on such exchange or listed
for trading on the Nasdaq Stock Market or other automated quotation system which
provides information as to the last sale price, the current value shall be the
average of the reported last sale prices of one share of Common Stock on such
exchange or system on the last trading day prior to the date of conversion, or
if, on such date, no such sale is made on such day, the average of the closing
bid and asked prices for such date on such exchange or system shall be used; or

               (ii) If the Common Stock is not so listed or admitted to unlisted
trading privileges, the current value shall be the mean the average of the
reported last bid and asked prices of one share of Common Stock as reported by
The Nasdaq Stock Market, the National Quotation Bureau, Inc. or other similar
reporting service, on the trading day prior to the date of conversion; or

               (iii) If the Common Stock is not so listed or admitted to
unlisted trading privileges and bid and asked prices are not so reported, the
current value of one share of Common Stock shall be an amount, not less than
book value, determined in such reasonable manner as may be prescribed by the
board of directors of the Company.

          (f) CONCERNING THE CONVERSION OF INTEREST. Notwithstanding any
contrary provisions of this Article 3, the holder of this Note shall not be
entitled to convert accrued interest on this Note if, in the reasonable opinion
of the Company, the issuance of the shares of Common Stock upon such conversion
of interest would result in the issuance upon conversion of principal and
interest would result

                                     - 6 -
<PAGE>

in the issuance of more than eight hundred forty thousand (840,000) shares of
Common Stock in the aggregate. To the extent that interest is not converted,
either pursuant to this Paragraph 3(f) or because the holder of this Note did
not elect to convert such interest into Common Stock, the Company shall pay
accrued interest on the portion of this Note that is being converted at the time
of such conversion.

                                   ARTICLE 4.
                                  SUBORDINATION

          (a) AGREEMENT OF SUBORDINATION. The Company, for itself, its
successors and assigns, covenants and agrees, and the Holder by his or her
acceptance of this Note likewise covenants and agrees, that the payment of the
principal of and interest on this Note is hereby expressly subordinated, to the
extent and in the manner hereinafter set forth, to the prior payment in full of
all Senior Indebtedness, as hereinafter defined. The provisions of this Article
4 shall constitute a continuing offer to all persons who, in reliance upon such
provision, become holders of, or continue to hold, Senior Indebtedness, and such
provisions are made for the benefit of the holders of Senior Indebtedness, and
such holders are hereby made obligees hereunder the same as if their names were
written herein as such, and they and/or each of them may proceed to enforce such
provisions.

          (b) COMPANY NOT TO MAKE PAYMENTS WITH RESPECT TO NOTE IN CERTAIN
CIRCUMSTANCES.

               (i) Upon the maturity of any Senior Indebtedness by lapse of
time, acceleration or otherwise, all principal thereof and premium, if any, and
interest thereon shall first be paid in full, or such payment duly provided for
in cash or in a manner satisfactory to the holder or holders of such Senior
Indebtedness, before any payment is made by the Company (A) on account of the
principal of or interest on this Note or (B) to acquire this Note.

               (ii) Upon the happening of an event of default with respect to
any Senior Indebtedness, as such event of default is defined therein or in the
instrument under which it is outstanding, permitting the holders to accelerate
the maturity thereof, then, unless and until such event of default shall have
been cured or waived or shall have ceased to exist, no payment shall be made by
the Company (A) on account of the principal of or interest on this Note or (B)
to acquire this Note.

               (iii) Subject to Paragraphs 4(b)(i) and (ii), as long as any
Senior Indebtedness shall be outstanding, (A) the Company shall not make any
payment of principal on this Note except upon the Maturity Date or as provided
in Article 1 of this Note, and (B) the Company may pay interest on this Note as
long as the payment of such principal or interest will not result in an event of
default under the terms of the instruments pursuant to which the Senior
Indebtedness is issued.

               (iv) In the event that, notwithstanding the provision of this
Paragraph 4(b), the Company shall make any payment to the Holder on account of
the principal of or interest on this Note after the happening of a default in
payment of the principal of or premium, if any, or interest on Senior
Indebtedness or after receipt by the Company of written notice of an event of
default with respect to any Senior Indebtedness, then unless and until such
default or event of default shall have been cured or waived or shall have ceased
to exist, such payment shall be held by the Holder in trust for the benefit of,
and shall be paid forthwith over and delivered to, the holders of Senior
Indebtedness (pro rata as to each of such holders on the basis of the respective
amounts of Senior Indebtedness held by them) or their representative or the
trustee under the indenture or other agreement (if any) pursuant to which any
instruments evidencing any Senior Indebtedness may have been issued, as their
respective interests may appear, for application to the payment of all Senior
Indebtedness remaining unpaid to the extent

                                     - 7 -
<PAGE>

necessary to pay all Senior Indebtedness in full in accordance with the terms of
such Senior Indebtedness, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

          (c) NOTES SUBORDINATED TO PRIOR PAYMENT OF ALL SENIOR INDEBTEDNESS ON
DISSOLUTION, LIQUIDATION OR REORGANIZATION OF COMPANY. Upon Any Distribution of
Assets of the Company upon any dissolution, winding up, liquidation or
reorganization of the Company (whether in bankruptcy, insolvency or receivership
proceedings or upon an assignment for the benefit of creditors or otherwise):

               (i) The holders of all Senior Indebtedness shall first be
entitled to receive payment in full of the principal thereof, premium, if any,
and interest due thereon before the Holder is entitled to receive any payment on
account of the principal of or interest on this Note (other than securities of
the Company or any other entity provided for by a plan of reorganization or
readjustment which stock and securities are subordinated to the payment of all
Senior Indebtedness and securities received in lieu thereof which may at the
time be outstanding); and

               (ii) Any payment or distribution of assets of the Company of any
kind or character whether in cash, property or securities (other than securities
that are subordinated to the payment of all Senior Indebtedness and securities
received in lieu thereof which may at the time be outstanding), to which the
holder of this Note would be entitled except for the provisions of this Article
4, shall be paid by the liquidating trustee or agent or other person making such
payment of distribution, whether a trustee in bankruptcy, a receiver or
liquidating trustee or other trustee or agent, directly to the holders of Senior
Indebtedness or their representative or representatives, or to the trustee or
trustees under any indenture under which any instruments evidencing any of such
Senior Indebtedness may have been issued, to the extent necessary to make
payment in full of all Senior Indebtedness remaining unpaid, after giving effect
to any concurrent payment or distribution or provision therefor to the holders
of such Senior Indebtedness.

               (iii) In the event that, notwithstanding the foregoing provision
of this Paragraph 4(c), any payment or distribution of assets of the Company of
any kind or character, whether in cash, property or securities (other than
shares representing equity of the Company as reorganized or readjusted, or
securities of the Company or any other entity provided for by a plan of
reorganization or readjustment which stock and securities are subordinated to
the payment of all Senior Indebtedness and securities received in lieu thereof
which may at the time be outstanding), shall be received by the Holder on
account of principal of or interest on this Note before all Senior Indebtedness
is paid in full, or effective provision made for its payment or distribution,
such payment or distribution shall be received and held in trust for and shall
be paid over to the holders of the Senior Indebtedness remaining unpaid or
unprovided for or their representative or representatives, or to the trustee or
trustees under any indenture under which any instruments evidencing any of such
Senior Indebtedness may have been issued, for application to the payment of such
Senior Indebtedness until all such Senior Indebtedness shall have been paid in
full, after giving effect to any concurrent payment or distribution or provision
therefor to the holders of such Senior Indebtedness.

          (d) HOLDER TO BE SUBROGATED TO RIGHT OF HOLDERS OF SENIOR
INDEBTEDNESS. Subject to the payment in full of all Senior Indebtedness, the
Holder shall be subrogated, pro rata, to the rights of the holders of Senior
Indebtedness to receive payments or distributions of assets of the Company
applicable to the Senior Indebtedness until all amounts owing on the Notes shall
be paid in full, and, for the purpose of such subrogation, no payments or
distributions to the holders of the Senior Indebtedness by or on behalf of the
Company or by or on behalf of the holder of this Notes by virtue of this Article
4 which otherwise would have been made to the holder of this Notes shall, as
between the Company and

                                     - 8 -
<PAGE>

the holder of this Note, be deemed to be payment by the Company to or on account
of the Senior Indebtedness, it being understood that the provisions of this
Article 4 are, and are intended solely, for the purpose of defining the relative
rights of the holders of the Notes, on the one hand, and the holders of the
Senior Indebtedness, on the other hand.

          (e) OBLIGATION OF THE COMPANY UNCONDITIONAL. Nothing contained in this
Article 4 or elsewhere in this Note is intended to or shall impair as between
the Company and the Holder, the obligation of the Company, which is absolute and
unconditional, to pay to the holder of this Note the principal of and interest
on this Note as and when the same shall become due and payable in accordance
with its terms, or is intended to or shall affect the relative rights of the
holder of this Note and creditors of the Company other than the holders of the
Senior Indebtedness, nor shall anything herein or therein prevent the holder of
this Note of this Note from exercising all remedies otherwise permitted by
applicable law upon default under this Note, subject to the rights, if any,
under this Article 4 of the holders of Senior Indebtedness in respect of cash,
property or securities of the Company received upon the exercise of any such
remedy; provided, however, that the Holder shall not exercise any remedies if
the exercise of such remedies would result in an event of default under the
terms of the Senior Indebtedness. Upon any distribution of assets of the Company
referred to in this Article 4, the Holder shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which any
dissolution, winding up, liquidation or reorganization proceedings are pending,
or a certificate of the liquidating trustee or agent or other person making any
distribution to the holder of this Note for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article 4. In no event shall any provision of
this Article 4 be interpreted as limiting or abrogating the right of the Holder
to convert principal and interest thereon pursuant to Article 3 of this Note.

          (f) SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR OMISSIONS OF THE
COMPANY OR HOLDERS OF SENIOR INDEBTEDNESS. No right of any present or future
holders of any Senior Indebtedness to enforce subordination as herein provided
shall at any time in any way be prejudiced or impaired by any act or failure to
act on the part of the Company or by any act or failure to act, in good faith,
by any such holder, or by any noncompliance by the Company with the terms,
provisions and covenants of this Note, regardless of any knowledge thereof which
any such holder may have or be otherwise charged with.

          (g) DEFINITION OF SENIOR INDEBTEDNESS. The term "Senior Indebtedness"
is defined to mean the principal of and premium, if any, and interest on and any
obligations of the Company with respect to the Company's indebtedness to Coast
Business Credit (a division of Southern Pacific Bank).

          (h) ADDITIONAL AGREEMENT. The Holder, by its acceptance of this Note,
agrees to execute any formal instruments of subordination which may be
reasonably requested by any holder of Senior Indebtedness.

                                   ARTICLE 5.
                        CERTAIN COVENANTS OF THE COMPANY

          (a) PIGGYBACK REGISTRATION RIGHTS.

               (i) In the event that, at any time during the year period
commencing on the date of this Note and ending December 31, 2003, the Company
registers its securities pursuant to the Securities Act in connection with a
public offering of its securities (other than a registration statement on Form
S-4 or S-8 or subsequent similar forms), whether for its own account or for the
account of selling

                                     - 9 -
<PAGE>

securityholders, the Company shall advise the Holder by written notice at least
two (2) weeks prior to the filing of any registration statement under the
Securities Act covering securities of the Company and will, upon the request of
the Holder, include in any such registration statement such information as may
be required to permit a public offering of the Holder's Registrable Shares, as
hereinafter defined; provided, however, that the Company shall not be required
to include such Registrable Shares in a registration statement relating to an
offering by the Company of securities for its own account if the managing
underwriter shall have advised the Company in writing that the inclusion of such
Registrable Shares will have a material adverse effect upon the ability of the
Company to sell securities for its own account, and provided further that the
holders are not treated less favorably than others having piggyback registration
rights. The Company shall keep such registration statement current and effective
for a period of twelve months from the effective date of such registration
statement or until such earlier date as all of the registered Registrable Shares
shall have been sold. In connection with a registration statement relating to an
underwritten offering of securities for the account of the Company, if requested
by the managing underwriter as a condition to the inclusion of the Registrable
Shares in the registration statement, the Holders shall agree not to sell or
otherwise distribute the Registrable Shares pursuant to the registration
statement for such period, not to exceed six months (the "lock-up period") as
the managing underwriter shall request, in which event the Company will keep the
registration statement effective for twelve months after the expiration of the
lock-up period. Notwithstanding the foregoing, if the registration statement is
on a Form S-3 or similar short-form registration statement, the Company shall
keep the registration statement current and effective until all of the
Registrable Shares shall have been sold.

               (ii) Notwithstanding the provisions of Paragraphs 5(a)(i) of this
Note, the Company's obligations to keep a registration statement current and
effective shall be suspended for an Excusable Reason, as hereinafter defined. If
an Excusable Reason shall occur, the Company shall give the holders prompt
notice thereof, and the holders shall refrain from thereafter making sales
pursuant to the registration statement until the cessation of the Excusable
Reason. An "Excusable Reason" shall mean the occurrence of negotiations with
respect to a material agreement prior to the either the announcement of the
execution of the agreement or the termination of the negotiations with respect
to such proposed agreement and other similar material corporate events to which
the Company is a party or expects to be a party if, in the reasonable judgment
of the Company, disclosure of the negotiations or other event would be required
to be included in a registration statement filed pursuant to the Securities Act
or filed with the Commission in a filing which would be incorporated by
reference in such a registration statement and such disclosure would be adverse
to the best interests of the Company; provided that the Company is continuing to
treat such negotiations as confidential and provided, further, that the period
during which the Company is precluded from filing the registration statement (or
suspended the use of an effective registration statement) as a result thereof
has not exceeded 60 days and provided, further, that the Company shall not be
permitted to suspend the use of an effective registration statement for an
Excusable Reason more than twice in any twelve-month period. In the event that
the use of a registration statement is suspended for an Excusable Reason, the
period during which the registration statement shall be kept current and
effective shall be extended for the number of days that the use of the
registration statement is suspended for an Excusable Reason; provided, that the
Company shall not be required to keep the registration statement current and
effective subsequent to the December 31, 2005. The Company shall advise the
holders in writing of the occurrence and termination of an Excusable Reason. The
Company shall not be in violation of this Paragraph 5(a)(ii) if such delays
exceed those provided for in this Paragraph 5(a)(ii) and are caused by action or
inaction by the Commission, the National Association of Securities Dealers,
Inc., NASD Regulation, Inc., any stock exchange or market or any state
securities commission or any holder.

                                     - 10 -
<PAGE>

               (iii) As used in this Paragraph 5(a), the Registrable Shares
shall mean the Conversion Shares which have not been sold either pursuant to a
registration statement or pursuant to Rule 144 of the Commission pursuant to the
Securities Act or any similar rule. Notwithstanding the foregoing, Registrable
Shares shall not include Conversion Shares held by the Holder if the Holder
holder may sell, pursuant to Rule 144 or any subsequent similar rule, all of the
Shares which the Holder proposes to sell without restriction on quantity or
method of sale.

               (iv) The following provision shall also be applicable:

                    (A) The Company shall bear the entire cost and expense of
any registration of securities initiated by it under this Paragraph 5(a). The
Holder shall, however, bear any transfer taxes or underwriting discounts or
commissions applicable to the Registrable Shares sold by the Holder pursuant
thereto and any personal expenses and legal or accounting expenses incurred by
the Holder in connection with the registration statement.

                    (B) The Company shall indemnify and hold harmless the Holder
and each underwriter, within the meaning of the Securities Act, who may purchase
from or sell for the Holder any Registrable Shares from and against any and all
losses, claims, damages and liabilities (including fees and expenses of counsel,
which counsel shall, if, in the reasonable opinion of counsel for the Company,
the representation by such counsel of both the Company and the indemnified
parties constitutes a conflict of interest under applicable Code of Professional
Responsibility, be separate from counsel for the Company, provided, that the
Company shall not be required to pay the fees of more than one firm representing
the Holders and all other parties who are entitled to indemnification as a
result of the same or similar allegations, which counsel shall be selected by
the holders of a majority of the shares held by all of such indemnified parties)
caused by any untrue statement or alleged untrue statement of a material fact
contained in the registration statement or any post-effective amendment thereto
or any registration statement under the Securities Act or any prospectus
included therein required to be filed or furnished by reason of this Paragraph
5(a) or any application or other filing under any state securities law caused by
any omission or alleged omissions to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading to
which such holder or any such underwriter or any of them may become subject
under the Securities Act, the Securities Exchange Act of 1934, as amended, or
other federal or state statutory law or regulation, at common law or otherwise,
except insofar as such losses, claims, damages or liabilities are caused by any
such untrue statement or alleged untrue statement or omission or alleged
omission based upon information furnished to the Company by any the Holder or
such underwriter expressly for use therein, which indemnification shall include
each person, if any, who controls any such underwriter within the meaning of the
Securities Act; provided, however, that the Holder and any such underwriter
shall at the same time indemnify the Company, its directors, each officer
signing the related registration statement, and each underwriter, if any,
engaged by the Company in connection with the registration statement, and each
person, if any, who controls the Company or any underwriter engaged by the
Company within the meaning of the Securities Act and each other holder whose
shares of Common Stock are included in the registration statement, in the manner
set forth in this Paragraph 5(a)(iv)(B), from and against any and all losses,
claims, damages and liabilities caused by any untrue statement or alleged untrue
statement of a material fact contained in any registration statement or any
prospectus required to be filed or furnished by reason of this Paragraph 5(a) or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, insofar as such losses, claims, damages or liabilities are caused by
any untrue statement or alleged untrue statement or omission based upon
information furnished to the Company by any such holder or underwriter expressly
for use therein.

<PAGE>

                    (C) Within five (5) days after receipt by an indemnified
party under Paragraph 5(a)(iv)(B) of this Note of notice of the commencement of
any action, such indemnified party shall, if a claim in respect thereof is to be
made against an indemnifying party under such subsection, notify the
indemnifying party in writing of the commencement thereof. The failure so to
notify the indemnifying party shall not relieve the indemnifying party from any
liability under said Paragraph 5(a)(iv)(B) as to the particular item for which
indemnification is then being sought, unless such indemnifying party was
materially prejudiced from such failure to give timely notice, and will not
relieve the indemnifying party from any liability that it may have to any
indemnified party otherwise than under said Paragraph 5(a)(iv)(B). If 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 therein and, to the extent that it may elect by written notice
delivered to the indemnified party promptly after receiving the aforesaid notice
from such indemnified party, to assume the defense thereof; provided, that if
the defendants in any such action include both the indemnified party and the
indemnifying party and either (i) the indemnifying party or parties agree, or
(ii) representation of both the indemnifying party or parties and the
indemnified party or parties by the same counsel is, in the opinion of counsel
for the indemnifying party, inappropriate under applicable standards of
professional conduct because of actual or potential conflicting interests
between them, then the indemnified party or parties shall have the right to
select separate counsel to assume such legal defense and to otherwise
participate in the defense of such action. The indemnifying party will not be
liable to such indemnified party under this Paragraph 5(a)(iv)(C) for any legal
or other expenses subsequently incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
counsel in connection with the assumption of legal defenses in accordance with
the proviso to the immediately preceding sentence (it being understood, however,
that the indemnifying party shall not be liable for the expenses of more than
one separate counsel reasonably acceptable to the indemnified parties (whether
pursuant to this Note or any other indemnification agreement if the
indemnification results from the same or substantially similar claims) in each
jurisdiction), such counsel to be selected as provided in Paragraph 5(a)(iv)(B)
of this Note; (ii) the indemnifying party shall not have employed counsel to
represent the indemnified party within a reasonable time after notice of
commencement of the action, or (iii) the indemnifying party has authorized the
employment of counsel for the indemnified party at the expense of the
indemnifying party. In no event shall an indemnifying party be liable under
Paragraphs 5(a)(iv)(B) and (C) of this Note for any settlement effected without
its written consent, which consent shall not be unreasonably withheld, of any
claim or action against an indemnified party.

                    (D) Neither the giving of any notice by any holder nor the
making of any request for prospectuses shall impose upon the Holder making such
request any obligation to sell any Registrable Shares.

                    (E) In connection with any registration statement filed
pursuant to this Paragraph 5(a), the Company shall supply prospectuses and
qualify the Registrable Shares for sale in such states as the Company is
otherwise registering or qualifying its securities and in such other states, not
to exceed ten, as the Holder may reasonably designates, provided, that the
Company shall not be required to qualify or register the Warrant Shares in any
jurisdiction where such qualification or registration would require the Company
to submit generally to the jurisdiction of such state.

                    (F) As a condition to the inclusion of the Holder's
Registrable Shares, the Holder shall:

                         (I) furnish the information and indemnification as set
forth in Paragraph 5(a)(iv)(B) of this Agreement;

                                     - 12 -
<PAGE>

                         (II) not sell any Shares pursuant to the registration
statement except in the manner set forth in the registration statement;

                         (III) comply with the prospectus delivery requirements
and the provisions of Regulation M of the Commission pursuant to the Securities
Act; and

                         (IV) agree not to sell or otherwise transfer any
Registrable Shares pursuant to a registration statement upon receipt of advice
from the Company that the registration statement is no longer current until the
Holder is advised that the Registrable Shares may be sold pursuant to the
registration statement.

          (b) PAYMENT OF INTEREST ON PRIOR NOTE. The Company acknowledges that
this Note was issued in payment and replacement of notes (the "Prior Note")
payable to Galt Asset Management, LLC in the aggregate principal amount of nine
hundred fifty thousand dollars ($950,000). As of the date of this Note, the
Company had not paid the accrued interest on the Prior Note. The Company shall
pay all accrued interest on the Prior Note on such date as the Company shall
have received gross proceeds of at least one million dollars ($1,000,000) in
cash from the sale of its debt or equity securities in one or more transactions,
which transactions need not be related transactions. Interest on the Prior Note
accrued at the rate of ten percent (10%) per annum through September 30, 2000
