                         ISSUANCE OF DETACHABLE WARRANTS

        SECTION 301. Warrants Issued. In consideration for Lender making the
loan as provided hereunder, and in consideration for the risks which Lender may
incur as a result of making said loan, and for other material consideration, the
Company shall, simultaneous with the execution of this Agreement, issue and
deliver to Lender a certificate evidencing detachable warrants, which shall
grant to the holders of said warrants the right to purchase from the Company
250,000 shares of the Company's Common Stock, with the right of exercise of
purchase of Common Stock to be exercised by the holder of the warrants at any
time after the issuance date and prior to 5:00 p.m. (PST) on December 14, 2004.
The warrant certificate shall represent 250,000 shares and be issued in favor of
CalWest. Each warrant is issued under the terms of the detachable warrant
certificate and shall grant to the holder the right to purchase form the Company
one (1) fully paid and non-assessable share for each warrant at an Exercise
Price of ten dollars ($10.00), subject to any adjustment based upon the
provisions of Section 303 of this Agreement (the "Exercise Price"). The Holder
of the Warrant certificate may exercise a warrant, in whole or in part, pursuant
to the terms specified in the holder's certificate and, at the holder's
election, the holder may assign all or a portion of the warrants to one or more
third party assignees.

        SECTION 302. Form of Warrant and Notice of Exercise. The form of the
warrant shall be substantially in the form of Exhibit "C" attached hereto, with
the Exercise Notice attached to said warrant to be utilized by the holder to
exercise the rights of purchase of shares under the warrant. The holders of a
warrant shall, at any time during the term of said warrant, have the right to
exercise said warrant by acquiring one (1) share of Common Stock of the Company
for each warrant so held.

        SECTION 303. Anti-Dilution Rights. The Company will not, by an voluntary
action, avoid or seek to avoid performance of any of the terms of the detachable
warrant, as is set forth in Section 301 hereinabove, but will at all times, in
good faith, carry out the provisions and intent of Section 301 and the warrants
issued under such Section and take all actions as may be necessary or
appropriate to protect against the impairment of any rights of Lender, or any
holder of the warrant to exercise rights thereunder and to purchase Common
Stock. In the event, at any time prior to the full exercise by any holder of the
warrant of all rights to purchase Common Stock, the Company shall sell or
otherwise transfer any Common Stock or adjust in any manner its capital
structure, the Company undertakes and agrees to make adjustments as may be
necessary to protect the holder of the warrant to purchase a number of shares of
Common Stock for a price per share equal to the price per share originally
contemplated under the terms of the Warrant and to adhere to and comply with all
provisions set forth in the warrant concerning anti-dilution rights extended to
the holder of the warrant.

        SECTION 304. Manner of Exercise of Warrants. The warrants, as
represented by the certificate as issued under the provisions of Section 301 of
this Agreement, shall be exercisable, at

                                      -10-
<PAGE>   12

the election of the holder of the warrant, either in their entirety or, from
time to time, for a part only the number of warrants specified in the
certificate issued to the holder of the warrant and in the Exercise Notice with
respect to the exercise thereof. If not all of the warrants evidenced by a
certificate are exercised at any time prior to the expiration of the warrant, a
new certificate or certificates (as the case may be) shall be promptly issued
for the balance of the warrants not so exercised, by the Company. All
certificates surrendered upon exercise of the warrants shall be cancelled by the
Company. Upon surrender of any certificate and payment of the exercise price,
the Company shall promptly issue and cause to be delivered to, or upon the
written order of, the holder of the warrant and, in such case, the name or names
as the holder of the warrant may designate, a certificate or other documents
representing the share or shares issuable upon the exercise of the warrants
evidenced by said certificate. The certificate representing the shares shall be
deemed to have been issued and any person so designated therein shall be deemed
to become a holder of record of such shares as of the date of the surrender of
any certificate and the payment of the exercise price by the holder of the
warrant.

        SECTION 305. Notice to Lender Prior to Certain Corporate Actions. In
case:

           (a) the Company shall authorize the granting to the holders of its
Common Stock generally of rights, Warrants or options to subscribe for or
purchase any shares of stock of any class or of any other rights; or

           (b) there shall be any reorganization of the Common Stock (other than
a change in the par value of the Common Stock), or any permissible consolidation
or merger to which the Company is a party, or any permissible conveyance,
transfer, sale or lease of the Company's properties and assets as, or
substantially as, an entity; or

           (c) there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then the Company shall cause to be given to Lender, in the manner provided in
Section 110 hereof, and with respect to the events described in subsections (a),
(b) and (c) of this Section 305, as promptly as possible, but in any even at
least twenty (20) days prior to the applicable date hereinafter specified, a
notice stating (i) the date on which the Company expects to file a Registration
Statement covering the Common Stock, or (ii) the date on which such
reorganization, reclassification, consolidation, merger, conveyance, transfer,
sale, lease, dissolution, liquidation, or winding up is expected to become
effective or occur, and, if applicable, the date as of which it is excepted that
holders of Common Stock or record shall be entitled to exchange their shares of
Common Stock for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, conveyance, transfer,
sale, lease, dissolution, liquidation, or winding up.

        SECTION 306. Reservation of Shares of Common Stock. The Company
covenants that it will at all times reserve and keep available, free from
preemptive rights, out of the aggregate of its authorized but unissued shares of
Common Stock, for the purpose of effecting issuance of

                                      -11-
<PAGE>   13

shares upon exercise of warrants, the full number of shares of Common Stock
deliverable upon exercise of a warrant.

        SECTION 307. Taxes Upon Exercise. The Company will pay any and all
documentary stamp or similar issue of transfer taxes payable in respect of the
issue or delivery of shares of Common Stock upon exercise of the warrants
pursuant thereto.

        SECTION 308. Covenants as to Common Stock. The Company covenants that
all shares of Common Stock which may be delivered upon exercise of the Warrants
will, upon delivery, be duly and validly issued and fully paid and
non-assessable, free of all liens and charges and not subject to any preemptive
rights.

        SECTION 309. Piggyback Registration Rights. If the Company shall
determine to register any of its securities, either for its own account or for
the account of a security holder or holders, other than a registration relating
solely to employee benefit plans, or a registration on any registration form
that does not permit secondary sales, the Company will promptly give to Lender
written notice thereof and use its best efforts to include in such registration
(and any related qualification under applicable Blue Sky laws or other
compliance), and any underwriting involved therein, Common Stock specified in a
written request made by Lender within twenty (20) days after the written notice
of the Company provided for above is given. Such written request may specify all
or a part of the Lender Common Stock. If the registration of which the Company
gives notice is for a registered public offering involving an underwriting, the
Company shall so advise as a part of the written notice given as required above.
In such event the right of Lender to registration shall be conditioned upon
Lender participation in such underwriting and the inclusion of its Common Stock
in the underwriting. Lender shall enter with the Company into an underwriting
agreement in customary form with the representative of the underwriter or
underwriters selected by the Company. Notwithstanding the above, if the
representative of the underwriters advises the Company in writing that marketing
factors require a limitation of the number of shares to be underwritten, the
representative may exclude Lender Common Stock from, or limit the number of
shares of Lender Common stock to be included in the registration and
underwriting. The number of shares of securities that are entitled to be
included in the registration and underwriting shall be allocated first to the
Company for securities being sold for its own account, then to Lender to the
extent of securities they have elected to sell for their own accounts, and
thereafter to all other owners of Common Stock with the right to participate in
such registration and underwriting pro rata in proportion to the percentage of
all outstanding Common Stock owned by each such person immediately prior to
commencement of such registration and underwriting. If any person does not agree
to the terms of any such underwriting, he shall be excluded therefrom by written
notice from the Company or the underwriter. Any Common Stock or other securities
excluded or withdrawn from such underwriting shall be withdrawn from such
registration. If shares are so withdrawn from the registration or if the number
of shares of Common Stock to be included in such registration is increased
during the period of such registration, the Company shall offer first to Lender
and then, if additional shares may be sold in the registration to all other
persons who have retained the right to include securities in the registration,
the right to include additional securities in the registration in an aggregate
amount equal to the number of shares so withdrawn, with such shares to be
allocated

                                      -12-
<PAGE>   14

among the persons requesting additional inclusion pro rata in proportion to the
percentage that each person's Common Stock represents of the total amount of
Common Stock owned by all such persons prior to commencement of such
registration and underwriting.

provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith by
appropriate proceedings.

        SECTION 404. DIVIDENDS/COMPENSATION. It shall not (a) declare, pay or
make any dividend or distribution (in cash, property or obligations) on any
shares of any class of its capital stock (now or hereafter outstanding) of the
Company or on any warrants, options or other rights with respect to any shares
of any class of capital stock (now or hereafter outstanding) of the Company, or

fund or other retirement of any shares of any class of capital stock (now or

prior written approval of the Company's Board of Directors and the
Administrative Agent, which approval will not be unreasonably withheld. No
non-cash compensation shall be paid to any employees of the Company without the
prior written approval of the Company's Board of Directors and the
Administrative Agent, which approval will not be unreasonably withheld.

        SECTION 602. ACCELERATION OF MATURITY, RESCISSION AND ANNULMENT; OTHER
REMEDIES.

           (a) LENDER'S REMEDIES.

               (i) Upon the occurrence of an Event of Default under any event
described in Section 501(a) (other than an Event of Default described in
Sections 501(a)(4) and 501(a)(5) hereof), then in every such case Lender may
declare the principal amounts of the Note to be due and payable immediately, by
a notice in writing to the Company and upon any such declaration such principal
amount shall become immediately due and payable. The Company specifically
acknowledges and agrees that the occurrence of any Event of Default under any
event described in Section 501(a) hereof will automatically cause the Note to be
in default, and all Events of Default under the Note must be cured before any
one Event of Default shall be deemed cured.

               (ii) At any time after such a declaration of acceleration with
respect to the Note has been made and before a judgment or decree for payment of
the money due has been obtained by Lender as hereinafter in this Article
provided, Lender may, by written notice to the Company, rescind and annul such
declaration and its consequences if, (1) the Company has paid to Lender a sum
sufficient to pay (A) all overdue interest on the Note, (B) the principal on the
Note which has become due otherwise than by such declaration of acceleration and
interest thereon at the Note Rate, (C) to the extent that payment of such
interest is lawful, interest upon overdue interest at the Note Rate, and (D) all
sums paid or advanced by Lender hereunder and the actual compensation, expenses,
disbursements and advances of Lender, its agents and counsel; and (2) all Events
of Default with respect to the Note, other than the nonpayment of the principal
of the Note which has become due solely by such declaration of acceleration,
have been cured or waived by Lender. No such rescission

                                      -21-
<PAGE>   23

shall affect any subsequent default or impair any right consequent thereon. In
the case of any Event of Default described in Section 501(a)(4) or 501(a)(5),
all unpaid principal of and accrued interest on the Note shall be due and
payable immediately without any declaration or other act on the part of Lender.

               (iii) Obligations of this Note are secured by the Security
Agreement dated August 1, 1996.

           (b) THE COMPANY'S REMEDIES. Upon the occurrence of an Event of
Default as described in Section 501(b) hereof, then the option amount referred
to in Section 901 hereof shall be limited to a number equal in value to the
amount already funded.

        SECTION 603. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT.

           (a) The Company covenants that if default is made in the payment of
any principal and/or interest on the Note when such principal and/or interest
becomes due and payable, whether at a time specified in the Note, at maturity of
the Note or in connection with any redemption or otherwise, the Company will,
upon demand of Lender, pay to it the whole amount then due and payable on the
Note for principal and interest and, to the extent that payment of such interest
shall be legally enforceable, interest on any overdue principal and-on any
overdue interest, at the Note Rate, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
Lender, its agents and counsel, it being understood that as to the Lenders, any
payments will be applied on a pro rata basis among the Lenders based on each
Lender's respective Note amount. If the Company fails to pay such amounts
forthwith upon such demand, Lender may prosecute a proceeding to judgment or
final decree and may enforce the same against the Company or any other obligor
on the Note and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or of any other
obligor on the Note, wherever situated, it being understood that any monies
collected shall be applied on a pro rata basis among the Lenders based on each
Lender's respective Note. In addition, Lender may give notice to customers of
the Company that all payments under contracts listed on Schedule 401 shall,
until further notice, be paid directly to Lender, and the Company consents to
each such notice.

           (b) If an Event of Default with respect to the Note occurs, Lender
may in its discretion proceed to protect and enforce its rights by such
appropriate judicial proceedings as it shall deem most effectual to protect and
enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Agreement or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy.

        SECTION 604. LENDER MAY FILE PROOFS OF CLAIM. In case of the pendency of
any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or of any other obligor on the Note or the property of the Company
or of such other obligor or their creditors, Lender (irrespective of whether the
principal of the Note shall then be due and payable as therein expressed or by

                                      -22-
<PAGE>   24

declaration or otherwise and irrespective of whether it shall have made any
demand on the Company for the payment of overdue principal or interest) shall be
entitled and empowered, by intervention in such proceeding or otherwise,

           (a) to file and prove a claim for the whole amount of principal and
interest owing and unpaid in respect of the Note and to file such other papers
and documents as may be necessary or advisable in order to have the claims of
Lender (including any claim to the right to own Common Stock or for the
reasonable compensation, expenses, disbursements and advances of Lender, its
agents and counsel) allowed in such judicial proceeding, and

           (b) to collect and receive any monies or other property payable or
deliverable on any such claims.

        SECTION 605. APPLICATION OF MONEY COLLECTED. Any money collected by
Lender pursuant to this Article V shall be applied in the following order, at
the date or dates fixed by Lender and, in case of the distribution of such money
on account of principal or interest, upon presentation of the Note and the
notation thereon of the payment if only partially said and upon surrender
thereof if fully paid:

           First: To the costs and expenses of Lender in collecting sums due it
hereunder;

           Second: To the payment of the amounts then due and unpaid first for
interest on and then for principal of all outstanding Notes, applied on a pro
rata basis among the Lenders based on each Lender's respective Note; and

           Third: To the payment of the remainder, if any, to the Company or any
other Person lawfully entitled thereto.

        SECTION 606. RIGHTS AND REMEDIES CUMULATIVE. No right or remedy herein
conferred upon or reserved to Lender is intended to be exclusive of any other
right or remedy, and every right and remedy shall, to the extent permitted by
law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

        SECTION 607. DELAY OR OMISSION NOT WAIVER. No delay or omission of
Lender to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default. Every right and remedy given by this Article V or by law may be
exercised from time to time, and as often as may be deemed expedient by Lender.

        SECTION 608. WAIVER OF STAY OR EXTENSION LAWS. The Company covenants (to
the extent that it may lawfully do so) that it will not at any time insist upon,
or plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay or extension law wherever enacted,

                                      -23-
<PAGE>   25

now or at any time hereafter in force, which may affect the covenants or the
performance of this Agreement; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to Lender, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE VII

                               REPORTS BY COMPANY

        SECTION 701. ANNUAL STATEMENT. The Company will deliver to Lender,
within 30 days after the end of each fiscal year of the Company, an Officer's
Certificate stating that to the best of such officer's knowledge, the Company
has fulfilled all its obligations under this Agreement throughout such year, or,
if there has been a default in the fulfillment of any such obligation and such
default is continuing, specifying each such default of which such officer has
knowledge, and the nature and status thereof.

        SECTION 702. REPORTS BY COMPANY. The Company shall file with Lender,
such information, documents and other reports, and such summaries thereof, as
Lender shall request, immediately upon request, but without request the Company
shall deliver to Lender audited financial statements of the Company prepared by
independent certified public accountants ("Accountants") within ninety (90) days
of the end of each Company fiscal year.

        SECTION 703. QUARTERLY FINANCIAL REPORTS. Throughout the term of this
Agreement and for so long as any amount remains unpaid under the Note, the
Company shall furnish Lender with copies of its quarterly financial reports no
later than forty-five (45) days following the end of the subject fiscal quarter.

                                  ARTICLE VIII

           CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER, SALE OR LEASE

        SECTION 801. COMPANY MAY CONSOLIDATE. ETC., ON CERTAIN TERMS. The
Company shall not consolidate with or merge into any other corporation or
convey, transfer, sell or lease its properties and assets as, or substantially
as, an entirety to any Person, issue any capital stock (including Common Stock)
of the Company unless (a) prior to such transaction Lender has released in
writing its Right of First Refusal as required by Section 702 hereof, and (b)
upon any such consolidation, merger, sale, conveyance or exchange of or by the
Company, (i) the Company is the continuing corporation and the Company's Common
Stock outstanding immediately prior to the merger is not exchanged for
securities, cash or other property of another corporation, (ii) there is an
exchange of the Note for other securities in connection with such transaction,
or (iii) the due and punctual payment of the principal of and interest on, the
Note, according to their tenor, and the due and punctual performance and
observance of all of the covenants and conditions of the Agreement

                                      -24-
<PAGE>   26

to be performed by the Company, are expressly assumed by a note supplemental to
the Note by the corporation formed by such consolidation, or whose securities,
cash or other property will immediately after the merger be owned, by virtue of
the merger, by the holders of Common Stock of the Company immediately prior to
the merger, or by the corporation that shall have acquired such property or
securities. Furthermore, the Company shall not consolidate with or merge into
any other corporation or convey, transfer, sell or lease its properties and
assets as, or substantially as, an entirety to any Person, or enter into any
statutory exchange of securities with another corporation, unless the Right of
First Refusal has been released and unless immediately after giving effect to
such transaction no Event of Default shall have occurred and be continuing, and
the Company shall have delivered to Lender an Officer's Certificate stating that
such transaction and such supplemental agreement comply with this Agreement.

        SECTION 802. RIGHT OF FIRST REFUSAL OF LENDERS. For so long as any
amounts due under the Note shall be outstanding, Lender shall have and retain
the first option to purchase any and all assets of the Company and any and all
capital stock (including Common Stock) of the Company, upon the same terms and
subject to the same conditions as may be offered to the Company by a third party
for such assets or capital stock; provided, however, that any non-cash
consideration offered for any such assets or capital stock shall be given its
then current market value in cash and Lender shall have the opportunity to pay
the amount of such cash in lieu of any non-cash consideration offered by a
prospective owner of any assets or capital stock on a pro rata basis as to the
Lender's exercise of that right. Immediately upon receipt of any offer to
purchase any assets or capital stock, or upon determining that the Company
desires to sell any assets or capital stock, the Company shall immediately
notify Lender of the assets and/or capital stock proposed to be bought and sold,
and of the terms of such proposed purchase and sale. Within twenty (20) days of
being so notified, Lenders shall notify either the Company and/or the owner of
the capital stock in question that they (or any one of them) will exercise the
right of first refusal granted herein ("Right of First Refusal"), or, in the
alternative, that they (or any one of them) thereby release such Right of First
Refusal and consents to the sale of the assets or capital stock on the terms
described. Any change in such terms shall give each Lender the right to once
again exercise or release its Right of First Refusal within an additional time
period identical to that specified above.

                                   ARTICLE IX

                        REDEMPTION OF NOTE BY THE COMPANY

        SECTION 901. RIGHT TO REDEEM. The Company may, at its option, redeem all
or, from time to time, any part of the Note, on any date prior to maturity, in
the manner specified in this Article VIII, at the original principal amount
thereof, plus accrued and unpaid interest, if any, to the date fixed for
redemption, but no such redemption shall in any way impair the right of Lender
to convert the Note into shares of Common Stock as specified in this Agreement
or in the Right of First Refusal granted hereunder.

        SECTION 902. NOTICE OF REDEMPTION.

                                      -25-
<PAGE>   27

           (a) In case the Company shall desire to exercise its right to redeem
all or any part of the Note pursuant to Section 801 hereof, it shall fix a date
for redemption (a "Redemption Date"), shall notify Lenders in writing of such
date, and shall mail or cause to be mailed a notice of such redemption (a
"Notice of Redemption") at least ten (10) and not more than thirty (30) days
prior to the date fixed for redemption to Lenders at their principal executive
offices. Such mailing shall be by first class mail. The Company agrees to
exercise said right of redemption on an equitable and pro rata basis among the
Lenders.

           (b) The Notice of Redemption shall specify the principal amount of
the Note to be redeemed, the Redemption Date for the Note, and the Redemption
Price at which the Note is to be redeemed, and shall state that payment of the
Redemption Price of the Note or portions thereof to be redeemed will be made on
surrender of the Note to be redeemed, that interest accrued to such Redemption
Date will be paid as specified in such notice, and that from and after such date
interest thereon will cease to accrue. In the event of full redemption of the
Note, such Notice of Redemption shall also state that the right to convert the
Note or portion thereof into Common Stock will expire at the close of business
on December 14, 2004.

           (c) On or prior to each Redemption Date specified in each Notice of
Redemption given as provided in this Section 802, the Company will pay to Lender
an amount of money sufficient to redeem on such Redemption Date the Note or
portion thereof so called for redemption at the appropriate Redemption Price,
together with accrued interest to the Redemption Date.

           (d) If the Note called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid, bear interest
from the date fixed for redemption at the Note Rate and the Note shall remain
convertible into Common Stock until December 14, 2004, or until all amounts due
under the Note have been repaid in full.

                                    ARTICLE X

              RIGHT TO CONVERT NOTE AND/OR RIGHT TO PURCHASE STOCK

        SECTION 1001. RIGHTS GRANTED. Subject to and upon compliance with the
provisions of this Article IX, and specifically Section 902 hereof, Lender shall
have the right, at its option, at any time or from time to time on or prior to
the close of business on December 14, 2004, to convert the principal amount of
the Note up to a value of $5,265,408 into, an aggregate of 526,541 shares of
Common Stock at a price of $10.00 per share (the "Conversion Price").

        SECTION 1002. ANTI-DILUTION RIGHTS OF LENDER. The Company will not, by
any voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of the conversion privilege set forth in Section 901 hereof,
but will at all times in good faith carry out the provisions and intent of
Section 901 and take all such action as may be necessary or appropriate to
protect against impairment of the rights of Lender to convert the Note into, or
to purchase, Common Stock. In the event that, at any time prior to full exercise
by Lender of its right to purchase such Common

                                      -26-
<PAGE>   28

Stock, the Company shall sell or otherwise transfer any Common Stock, the
Company undertakes and agrees to make any adjustments that may be necessary to
permit Lender to purchase an equal number of shares of the Common Stock for a
per share price equal to the per share price paid by such other purchaser or
transferee, including, if necessary, refunding to Lender any sums necessary to
cause Lender to receive the benefit of this Section 902, such benefit to survive
the repayment of the Note and to be applicable with respect to issuances of
Common Stock until December 14, 1999.

                                      -27-
<PAGE>   29

        SECTION 1003. MANNER OF EXERCISE OF CONVERSION PRIVILEGE. In order to
exercise the conversion privilege, Lender shall surrender the Note, duly
endorsed or assigned to the Company or in blank, at the office of the Company,
together with the Conversion Notice duly executed, that Lender elects to convert
the Note or the portion thereof specified in said Conversion Notice or,
alternatively, that Lender will purchase such Common Stock. Such Conversion
Notice shall also state the name or names, together with the address or
addresses in which the certificate or certificates for shares of Common Stock
which shall be issuable in such conversion or purchase shall be issued as
promptly as practicable after the surrender of the Note and the receipt of such
Conversion Notice, the Company shall issue and deliver to Lender, or on Lender's
written order, a certificate or certificates for the number of full shares of
Common Stock issuable upon the conversion of the Note or portion thereof in
accordance with the provisions of this Article IX. In case the Note shall be
surrendered for partial conversion, the Company shall execute and deliver to or
upon the order of Lender, at the expense of the Company, a new note or notes in
authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Note. Each conversion shall be deemed to
have been effected immediately prior to the close of business on the date on
which the Note shall have been surrendered and such Conversion Notice received
by the Company as aforesaid, and the Person or Persons in whose name or names
any certificate or certificates for shares of Common Stock shall be issuable
upon such conversion or purchase shall be deemed to have become the holder or
holders of record of the shares represented thereby at such time on such date.

        SECTION 1004. NOTICE TO LENDER PRIOR TO CERTAIN CORPORATE ACTIONS. In
case:

           (a) the Company shall authorize the granting to the holders of its
Common Stock generally of rights, warrants or options to subscribe for or
purchase any shares of stock of any class or of any other rights; or

           (b) there shall be any reorganization or reclassification of the
Common Stock (other than a change in the par value of the Common Stock), or any
permissible consolidation or merger to which the Company is a party, or any
permissible conveyance, transfer, sale or lease of the Company's properties and
assets as, or substantially as, an entity; or

           (c) there shall be a voluntary or in-voluntary dissolution,
liquidation or winding-up of the Company;

then the Company shall cause to be given to Lender, in the manner provided in
Section 110 hereof, and with respect to the events described in subsections (a),
(b) and (c) of this Section 904, as promptly as possible, but in any event at
least twenty (20) days prior to the applicable date hereinafter specified, a
notice stating (i) the date on which the Company expects to file a Registration
Statement covering the Common Stock, or (ii) the date on which such
reorganization, reclassification, consolidation, merger, conveyance, transfer,
sale, lease, dissolution, liquidation, or winding-up is expected to become
effective or occur, and, if applicable, the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities or other property deliverable upon such
reorganization, reclassification,

                                      -28-
<PAGE>   30

consolidation, merger, conveyance, transfer, sale, lease, dissolution,
liquidation, or winding-up, subject to compliance with the Right of First
Refusal required by Section 702 hereof.

        SECTION 1005. RESERVATION OF SHARES OF COMMON STOCK. The Company
covenants that it will at all times reserve and keep available, free from
preemptive rights, out of the aggregate of its authorized but unissued shares of
Common Stock, for the purpose of effecting conversion of the Note, the full
number of shares of Common Stock deliverable upon the conversion of the Note.

        SECTION 1006. TAXES UPON CONVERSION. The Company will pay any and all
documentary stamp or similar issue or transfer taxes payable in respect of the
issue or delivery of shares of Common Stock on conversion of the Note pursuant
hereto.

        SECTION 1007. COVENANTS AS TO COMMON STOCK. The Company covenants that
all shares of Common Stock which may be delivered upon conversion of the Note
will, upon delivery, be duly and validly issued and fully paid and
non-assessable, free of all liens and charges and not subject to any preemptive
rights.

        SECTION 1008. PIGGYBACK REGISTRATION RIGHTS. If the Company shall
determine to register any of its securities, either for its own account or for
the account of a security holder or holders, other than a registration relating
solely to employee benefit plans, or a registration on any registration form
that does not permit secondary sales, the Company will promptly give to Lender
written notice thereof and use its best efforts to include in such registration
(and any related qualification under applicable Blue Sky laws or other
compliance), and any underwriting involved therein, Common Stock specified in a
written request made by Lender within twenty (20) days after the written notice
of the Company provided for above is given. Such written request may specify all
or a part of Lender's Common Stock. If the registration of which the Company
gives notice is for a registered public offering involving an underwriting, the
company shall so advise as a part of the written notice given as required above.
In such event the right of Lender to registration shall be conditioned upon
Lender's participation in such underwriting and the inclusion of its Common
Stock in the underwriting. Lender shall enter with the Company into an
underwriting agreement in customary form with the representative of the
underwriter or underwriters selected by the Company. Notwithstanding the above,
if the representative of the underwriters advises the Company in writing that
marketing factors require a limitation of the number of shares to be
underwritten, the representative may exclude Lender's Common Stock from, or
limit the number of shares of Lender's Common Stock to be included in, the
registration and underwriting. The number of shares of securities that are
entitled to be included in the registration and underwriting shall be allocated
first to the Company for securities being sold for its own account, then to

        MICRO GENERAL CORPORATION, a corporation duly organized and existing

have been disbursed by Lender and which at that time remains unpaid, together
with simple interest thereon from the date hereof at the rate of ten percent

        This Note may be prepaid in whole or in part at any time with the prior

the right to convert the then-outstanding principal balance hereof into the
subject shares of Common Stock throughout the five (5) year term of this Note at

set forth on the face hereof, and is limited to the aggregate principal amount
of $5,265,408 issued under and pursuant to that certain Convertible Note

the "Agreement"), duly executed and delivered by the Company and Lender, to
which Agreement reference is hereby made for a further description of the
rights, limitation of rights, obligations, and duties thereunder of the Company
and Lender. In case an Event of Default shall have occurred under this Note or
under the Agreement (as the term "Event of Default" is defined in said
Agreement), the principal balance hereof and all accrued but unpaid interest
thereon may be declared, and upon such declaration shall become, due and
payable, in the manner, with the effect and subject to the conditions provided
in the Agreement.

        Reference is hereby made to the further provisions of the Agreement,
including, without limitation, provisions giving the Lender of this Note the
right to convert this Note into Common Stock on the terms and subject to the
limitations more fully specified in the Agreement. Such further provisions shall
for all purposes have the same effect as though fully set forth at this place.
Capitalized terms used in this Note and not otherwise defined still have the
meanings assigned to such terms in the Agreement.

        IN WITNESS WHEREOF, the Company has caused this instrument to be signed
