ITEM 5.    OTHER EVENTS.

(a)  PRIVATE PLACEMENT FINANCING. On November 24, 1999, Soligen Technologies,
Inc. (the "Company"), entered into a Series B Convertible Preferred Stock
Purchase Agreement (the "Stock Purchase Agreement") providing for the private
placement of 8,425,000 shares of a newly authorized series of preferred stock
("Series B Preferred"). A copy of the Stock Purchase Agreement is attached as an
exhibit to this report. The Company received gross proceeds of $1,685,000 from
the sale of 8,425,000 shares of Series B Preferred to thirty three (33) private
investors pursuant to the Stock Purchase Agreement. The purchasers of Series B
Preferred also received Common Stock purchase warrants exercisable for a
cumulative total of 3,622,750 shares of the Company's Common Stock at an
exercise price of $0.20 per share. These warrants are exercisable for a period
of one year, commencing November 24, 1999. A copy of the warrant is attached as
an exhibit to this report. The financing was completed in accordance with the
exemption provided by Rule 506 of Regulation D.

In connection with the financing, the Company paid a cash finder's fee in the
approximate amount of $100,000. In addition, the finders received warrants
exercisable for 498,750 shares of common stock at a price of $0.20 per share.
These warrants are exercisable for a period of one year, commencing November 24,
1999.

At a special stockholders meeting held on April 20, 1998, the Company's
stockholders approved an amendment to the Company's Articles of Incorporation
authorizing the issuance of up to 10,000,000 shares of preferred stock. This
amendment authorizes the Company's Board of Directors to issue preferred stock
in one or more series on terms approved by the Board of Directors without the
necessity of further action or approval by the stockholders. Pursuant to this
authority, the Company's Board of Directors has authorized the issuance of up to
8,425,000 shares of Series B Preferred Stock having rights and preferences as
set forth in a Statement of Rights and Preferences (the "Statement") filed with
the Secretary of State of Wyoming on November 23, 1999. A copy of the Statement
is attached as an exhibit to this report. The following is a summary of certain
terms of the Series B Preferred, and reference is made to the Statement for a
complete description of the rights and preferences of the Series B Preferred.

The Series B Preferred is not entitled to any fixed or guaranteed dividend. Upon
a liquidation of the Company, the Series B Preferred is entitled to receive a
distribution of $0.20 per share in preference to any distribution to holders of
common stock or junior preferred stock. The approval of the holders of at least
two-thirds of the outstanding shares of Series B Preferred is required for
certain significant corporate actions, including mergers and sales of
substantially all of the Company's assets.

Each share of Series B Preferred is initially convertible into one share of the
Company's Common Stock, subject to adjustment for recapitalizations, stock
splits and similar events. Subject to certain exceptions, the Series B
conversion ratio is subject to adjustment in the event the Company issues shares
of Common Stock for no consideration or for a consideration less than the fair
market value of the Common Stock as of the date of such issuance. The Series B
Preferred automatically converts into common stock in the event the average
trading price of the Company's common stock over 60 consecutive trading days is
greater than $1.00 per share and the cumulative trading volume during such 60
day period is at least 1,000,000 shares, if traded on a national securities
exchange, or 1,500,000 shares if traded on NASDAQ or over-the-counter. The
Series B Preferred also automatically converts into common stock in the event
the Company completes an underwritten public offering in which the Company
receives gross proceeds of


                                       2
<PAGE>


at least $10,000,000 and at a per share price of at least $1.00 per share
(subject to adjustment for stock splits, recapitalizations, etc.).

The holders of Series B Preferred may tender their shares for redemption at a
per share price equal to 150% of the liquidation preference in the event of a
Change of Control (as defined in the Statement). In addition, the Company may,
at its option, redeem the Series B Preferred at a per share price equal to 150%
of the liquidation preference in the event that, from and after November 24,
2000, the common stock trades above $0.75 per share for sixty (60) consecutive
trading days.

Purchasers of Series B Preferred are also parties to an Investor Rights
Agreement (a copy of which is attached as an exhibit to this Report), which
grants certain demand and "piggyback" registration rights. The holders of Series
B Preferred, voting as a separate class, are entitled to elect one member of the
Company's Board of Directors.

(b)  CONVERSION AGREEMENT. In conjunction with completion of the Series B
Preferred financing described in paragraph 5(a), the Company entered into a
Conversion Agreement with the holders of the Company's Series A Convertible
Preferred Stock ("Series A Preferred"). Pursuant to this Agreement, on November
24, 1999, all outstanding shares of Series A Preferred were converted into
2,023,874 shares of the Company's Common Stock in accordance with the Company's
Articles of Incorporation. In consideration of the agreement of holders of
Series A Preferred to make such conversion, the Company issued a cumulative
total of 404,697 additional shares of Common Stock to the holders of Series A
Preferred. These additional shares are entitled to the same registration rights
granted to the holders of Series B Preferred.

                             RIGHTS AND PREFERENCES OF
                                SERIES B CONVERTIBLE
                                  PREFERRED STOCK
                                         OF
                             SOLIGEN TECHNOLOGIES, INC.

       9 (c)  The Series B Convertible Preferred Stock ("Series B Preferred
Stock") shall consist of eight million four hundred twenty-five thousand
(8,425,000) shares having the following particular rights and preferences:


(i)    DIVIDENDS.  Holders of shares of Series B Preferred Stock shall not be
entitled to any fixed or guaranteed dividends, nor to any cumulative dividend
rights, but shall be entitled to receive out of the earnings and assets of the
Corporation only such dividends as may be lawfully declared on such dates or may
be determined in the discretion of the Board of Directors.  No dividend or other
distribution whatsoever shall be declared or paid on Common Shares or Preferred
Shares ranking junior to the rights of the Series B Preferred Stock unless a
dividend or other distribution shall be simultaneously paid on each outstanding
share of Series B Preferred Stock which is equal to or greater than the product
of (i) the dividend or distribution proposed to be declared or paid on each
share of Common Shares or such junior Preferred Shares (on an as-converted to
Common Shares basis) times (ii) the number of Common Shares into which each such
share of Series B Preferred Stock is then convertible under Subsection 9(c)(iii)
below.  In any event, no dividend or other distribution shall be paid at any
time on Series B Preferred Stock, on any other class or series of Preferred
Shares, or on Common Shares which would have the effect of reducing the net
assets of the Corporation below the aggregate preferential amount (determined in
accordance with Subsection 9(c)(ii) below) payable to holders of Series B
Preferred Stock upon liquidation or dissolution of the Corporation.

(ii)   LIQUIDATION.

       (a)    LIQUIDATION PREFERENCES.  Upon liquidation or dissolution of the
Corporation, whether voluntary or involuntary, each share of Series B Preferred
Stock shall entitle its holder to receive, out of the assets of the Corporation
available for distribution to shareholders, whether from capital, surplus or
earnings, and before any distribution of such assets to the holders of Common
Shares or Preferred Shares ranking junior to the rights of the Series B
Preferred Stock, a liquidation preference of twenty cents ($0.20) per share (as
adjusted for stock splits, dividends, consolidations, recapitalizations and
similar events), plus any unpaid dividends declared pursuant to Subsection
9(c)(i) above.  If the assets of the Corporation available for distribution to
shareholders are insufficient to satisfy in full the liquidation preferences for
Series B Preferred Stock and all the other classes or series of Preferred Shares
entitled to a stated liquidation preference, then the holders of Series A and
Series B Preferred Stock shall share ratably in such distribution in proportion
to their respective stated liquidation preferences, and within each such series,
each holder shall be entitled to receive the same distribution for each share of
such series.  After setting apart or paying in full the liquidation preferences
on Series A and Series B


                                       1
<PAGE>


Preferred Stock, further distribution of the remaining available assets shall
be made pro rata to the holders of any other classes or series of Preferred
Shares entitled to a stated preference on liquidation, and then pro rata to
the holders of Common Shares.

       (b)    DEEMED LIQUIDATIONS.  The sale of all or substantially all of the
Corporation's assets, or the acquisition of the Corporation by another entity by
means of merger, consolidation, share exchange, reorganization or otherwise,
pursuant to which shares of the Corporation's capital stock are converted into
cash, securities or other property of the acquiring entity or any of its
affiliates, shall be regarded as a liquidation within the meaning of this
Subsection 9(c)(ii); PROVIDED, HOWEVER, that each holder of Series B Preferred
Stock shall have the right to elect the benefits of the provisions of Subsection
9(c)(iii) or other applicable conversion provisions in lieu of receiving payment
of the liquidation preference in the event of the liquidation, dissolution or
winding up of the Corporation pursuant to this Subsection 9(c)(ii); PROVIDED,
FURTHER, that this provision shall not apply if the holders of the Corporation's
voting capital stock immediately prior to such merger, consolidation, share
exchange or reorganization beneficially own, directly or indirectly, more than
fifty percent (50%) of the combined voting power of the capital stock of the
corporation resulting from such merger, consolidation, share exchange or
reorganization.

       (c)    NONCASH DISTRIBUTION.  Whenever the distribution provided for in
this Subsection 9(c)(ii) shall be payable in property other than cash, the value
of such distribution shall be the fair market value of such property as
determined in good faith by the Corporation's Board of Directors.

(iii)  CONVERSION.

       (a)    AUTOMATIC CONVERSIONS.  At any time or times, part or all of any
holder's shares of Series B Preferred Stock may be converted into Common Shares
at the conversion price then in effect, in the manner specified below, and upon
delivery by the holder thereof of written notice of conversion, specifying the
number of such shares to be converted, to the Corporation at its principal
business offices (or at the office of any transfer agent for shares of Series B
Preferred Stock or Common Shares), accompanied by the certificate or
certificates for the shares to be converted, duly endorsed in blank or
accompanied by signed instruments appropriate for the transfer thereof.  In
addition, all of the outstanding shares of Series B Preferred Stock shall, at
the election of the Corporation's Board of Directors, be automatically converted
into Common Shares in the manner specified below upon the occurrence of either
of the following events (an "Automatic Conversion Event"):

              (1)    Immediately prior to such time as the Corporation shall
close a firm commitment underwritten public offering of Common Shares pursuant
to a registration statement filed pursuant to the Securities Act of 1933, as
amended, ("Securities Act") in which the Corporation receives gross proceeds of
at least ten million dollars ($10,000,000) and at a price equal to or greater
than one dollar ($1.00) per share (adjusted for stock splits, dividends,
consolidations, recapitalizations, and similar events); or

              (2)    At any such time as (a) the Common Shares shall have
traded above one dollar ($1.00) per share (as adjusted for stock splits,
dividends, consolidations, recapitalizations


                                       2
<PAGE>


and similar events) for sixty (60) consecutive trading days on a national
securities exchange or NASDAQ, or (b) the closing bid price for the Common
Shares quoted by an established quotation service for over-the-counter
securities shall be above one dollar ($1.00) per share (as adjusted for stock
splits, dividends, consolidations, recapitalizations and similar events) for
sixty (60) consecutive trading days; and the cumulative trading volume of the
Common Shares during such sixty (60) consecutive trading days is equal to or
greater than one million (1,000,000) Common Shares, if traded on a national
securities exchange, or one million five hundred thousand (1,500,000) Common
Shares, if traded on NASDAQ or traded over-the-counter.

       (b)    CONVERSION PROCEDURES.  The Common Shares (or other shares,
securities or property) into which the outstanding shares of Series B
Preferred Stock are convertible as computed in this Subsection 9(c)(iii)
shall, promptly after delivery to the Corporation of written notice of any
conversion election, or promptly after the occurrence of any Automatic
Conversion Event, and upon surrender to the Corporation of the certificates
representing the Series B Preferred Stock to be converted, duly endorsed in
blank or accompanied by signed instruments appropriate for transfer, be
issued and delivered as soon as practicable to the holders of Series B
Preferred Stock in due and proper form, and shall be fully paid and
nonassessable; as to any portion of the shares so surrendered which are not
subject to such conversion election, the Corporation shall promptly issue to
the holder thereof a certificate in due and proper form representing the
shares of Series B Preferred Stock which have not been so converted.
Conversion shall be deemed to have been made at the close of business on the
date that notice of such written election was given by the holder, or on the
date that the Corporation's Board of Directors elected to declare an
Automatic Conversion Event, irrespective of the date on which such surrender
or issuance may occur, and as of such election date each such holder shall be
deemed to have become the record holder of such respective number of Common
Shares (or other shares, securities or property), and the Series B Preferred
Stock so converted shall be deemed forthwith cancelled and shall not
thereafter be deemed authorized or subject to reissuance.  No adjustment
shall be made in the number of Common Shares issuable upon conversion to
reflect declared, but unpaid, dividends on Series B Preferred Stock, but such
dividends for which the payment date has passed shall be paid in cash as of
the date of conversion of the shares of Series B Preferred Stock as to which
they are owing. The Corporation shall not be required to issue any fraction
of Common Shares upon conversion of Series B Preferred Stock; if any fraction
of Common Shares would, except for the foregoing clause, be issuable to any
holder on the conversion of Series B Preferred Stock, the Corporation shall
pay to each holder of such converted Series B Preferred Stock an amount in
cash equal to the then current fair market value of such fractional interest.

       (c)    CONVERSION RATES.  The number of Common Shares issuable with
respect to any share of Series B Preferred Stock shall be determined by dividing
twenty cents ($0.20) by the conversion price then in effect at the time of
conversion for such series (the "Series B Conversion Price"), which shall
initially be twenty cents ($0.20).

       (d)    ADJUSTMENT OF SERIES B CONVERSION PRICE UPON ISSUANCE OF COMMON
SHARES OR CONVERTIBLE SECURITIES.  Except as provided in Subsection
9(c)(iii)(e), if, after the first date that a share of Series B Preferred Stock
is issued, the Corporation shall issue or sell, or, in accordance with
Subsections 9(c)(iii)(d)(1) through 9(c)(iii)(d)(5), is deemed to have issued or
sold, any Common Shares, or any stock or security convertible into or
exchangeable for Common Shares,


                                       3
<PAGE>


without consideration or for a consideration per share less than the
per-share "Fair Market Value" of the Common Shares as of the end of the day
immediately preceding such issuance or sale, or deemed issuance or sale in
accordance with Subsections 9(c)(iii)(d)(1) through 9(c)(iii)(d)(5), then,
forthwith upon each such issue or sale or deemed issuance or sale, the Series
B Conversion Price shall be reduced to the price determined by dividing (i)
an amount equal to the sum of (x) the number of Common Shares of the
Corporation outstanding immediately prior to such issue or sale (including
the number of Common Shares issuable pursuant to exercise of all outstanding
options and warrants and the conversion of all of the outstanding Preferred
Shares at the then existing conversion prices) multiplied by the then
existing Series B Conversion Price plus (y) the consideration, if any,
received by the Corporation upon such issue or sale, by (ii) the sum of the
number of Common Shares outstanding immediately after such issue or sale
(including the Common Shares issuable pursuant to conversion or exchange of
the securities or stock issued or sold in such issue or sale) plus the number
of Common Shares issuable pursuant to exercise of all outstanding options and
warrants and the conversion of all of the outstanding Preferred Shares at the
conversion prices existing before such issue or sale. "Fair Market Value"
shall mean (i) if the Common Shares are publicly traded, then (a) if the
Common Shares are then traded on a national securities exchange on the date
in question, the average of the high and low prices of the Common Shares on
the principal national securities exchange on which the Common Shares are
traded; (b) if the Common Shares are then traded on the NASDAQ National
Market System on the date in question, the last reported per-share sales
price of the Common Shares on the NASDAQ National Market System; or (c) if
the Common Shares are then traded on the over-the-counter market on the date
in question, the last reported per-share sales price; PROVIDED THAT if there
have been no sales reported in the most recent two trading days at the time
of determination, then the closing bid price (or average of bid prices) last
quoted by an established quotation service for over-the-counter securities,
or (ii) if the Common Shares are not publicly traded on the date in question,
then the per-share fair market value of the Common Shares as determined in
good faith by the Corporation's Board of Directors, after taking into
consideration all factors that it deems appropriate, including, without
limitation, recent sale and offer prices of the Common Shares in private
transactions negotiated at arm's length.

       For purposes of this Subsection 9(c)(iii)(d), the following Subsections
9(c)(iii)(d)(1) to 9(c)(iii)(d)(5) shall also be applicable:

              (1)    ISSUANCE OF RIGHTS OR OPTIONS.  In case at any time the
Corporation shall in any manner grant (whether directly or by assumption in a
merger or otherwise) any options, warrants or other rights to subscribe for or
to purchase Common Shares or any stock or security convertible into or
exchangeable for Common Shares (such options, warrants and rights being called
"Options" and such convertible or exchangeable stock or securities being called
"Convertible Securities") whether or not such Options or the right to convert or
exchange any such Convertible Securities are immediately exercisable, and the
price per share for which Common Shares is issuable upon the exercise of such
Options or upon the conversion or exchange of such Convertible Securities
(determined by dividing (i) the total amount, if any, received or receivable by
the Corporation as consideration for the granting of such Options, plus the
minimum aggregate amount of additional consideration payable to the Corporation
upon the exercise of all such Options, plus, in the case of such Options which
relate to Convertible Securities, the minimum aggregate amount of additional
consideration, if any, payable upon the issue or sale of such Convertible
Securities and upon the conversion or exchange thereof, by (ii)


                                       4
<PAGE>


the Common Shares issuable upon the exercise of such Options or upon the
conversion or exchange of all such Convertible Securities issuable upon the
exercise of such Options) shall be less than the per-share Fair Market Value
of the Common Shares as of the end of the day immediately preceding the
granting of such Options, then the total maximum number of Common Shares
issuable upon the exercise of such Options or upon conversion or exchange of
the total maximum amount of such Convertible Securities shall be deemed to
have been issued for such price per share as of the date of granting of such
Options.  Except as otherwise provided in Subsection 9(c)(iii)(d)(3), no
adjustment of the Series B Conversion Price shall be made upon the actual
issuance of the Common Shares or Convertible Securities upon exercise of such
Options or upon the actual issuance of such Common Shares upon conversion or
exchange of such Convertible Securities.

              (2)    ISSUANCE OF CONVERTIBLE SECURITIES.  In case the
Corporation shall in any manner issue (whether directly or by assumption in a
merger or otherwise) or sell any Convertible Securities, whether or not the
rights to exchange or convert any such Convertible Securities are immediately
exercisable, and the price per share for which the Common Shares are issuable
upon such conversion or exchange (determined by dividing (i) the total amount
received or receivable by the Corporation as consideration for the issuance or
sale of such Convertible Securities, plus the minimum aggregate amount of
additional consideration, if any, payable to the Corporation upon the conversion
or exchange thereof, by (ii) the total maximum number of Common Shares issuable
upon the conversion or exchange of all such Convertible Securities) shall be
less than the per-share Fair Market Value of the Common Shares as of the end of
the day immediately preceding such issuance or sale, then the Common Shares
issuable upon conversion or exchange of all such Convertible Securities shall be
deemed to have been issued for such price per share as of the date of the
issuance or sale of such Convertible Securities and thereafter shall be deemed
to be outstanding, PROVIDED that (a) except as otherwise provided in Subsection
9(c)(iii)(d)(3), no adjustment of the Series B Conversion Price shall be made
upon the actual issuance of such Common Shares upon conversion or exchange of
such Convertible Securities and (b) if any such issuance or sale of such
Convertible Securities is made upon exercise of any Options to purchase any such
Convertible Securities for which adjustments of the Series B Conversion Price
have been or are to be made pursuant to other provisions of this Subsection
9(c)(iii)(d), no further adjustment of the Conversion Price shall be made by
reason of such issuance or sale.

              (3)    CHANGE IN OPTION PRICE OR CONVERSION RATE.  Upon the
happening of any of the following events, namely, if the purchase price provided
for in any Option referred to in Subsection 9(c)(iii)(d)(1), or the rate at
which Convertible Securities referred to in Subsection 9(c)(iii)(d)(2) are
convertible into or exchangeable for Common Shares shall change at any time
(including, but not limited to, changes under or by reason of provisions
designed to protect against dilution), the Series B Conversion Price in effect
at the time of such event shall forthwith be readjusted to the Series B
Conversion Price which would have been in effect at such time had such Options
or Convertible Securities still outstanding provided for such changed purchase
price, additional consideration or conversion rate, as the case may be, at the
time initially granted, issued or sold; and on the expiration of any such Option
or termination of any such right to convert or exchange such Convertible
Securities, the Conversion Price then in effect hereunder shall forthwith be
increased to the Conversion Price which should have been in effect


                                       5
<PAGE>


at the time of such expiration or termination had such Option or Convertible
Securities, to the extent outstanding immediately prior to such expiration or
termination, never been issued.

              (4)    CONSIDERATION FOR SHARES.  In case any Common Shares,
Options or Convertible Securities shall be issued or sold for cash, the
consideration received therefor shall be deemed to be the amount received by
the Corporation therefor, without deduction therefrom of any expenses
incurred or any underwriting commissions or concessions paid or allowed by
the Corporation in connection therewith.  In case Common Shares, Options or
Convertible Securities shall be issued or sold for a consideration in whole
or in part other than cash, the amount of the consideration other than cash
received by the Corporation shall be deemed to be the fair market value of
such consideration as determined in good faith by the Board of Directors of
the Corporation, without deduction of any expenses incurred or any
underwriting commissions or concessions paid or allowed by the Corporation in
connection therewith.  In case any Options shall be issued in connection with
the issuance or sale of other securities of the Corporation, together
comprising one integral transaction in which no specific consideration is
allocated to such Options by the parties thereto, such Options shall be
deemed to have been issued for such consideration as determined in good faith
by the Board of Directors of the Corporation.

              (5)    RECORD DATE.  In case the Corporation shall take a
record of the holders of its Common Shares for the purpose of entitling them
(i) to receive a dividend or other distribution payable in Common Shares,
Options or Convertible Securities, or (ii) to subscribe for or purchase
Common Shares, Options or Convertible Securities, then such record date shall
be deemed to be the date of the issuance or sale of the Common Shares deemed
to have been issued or sold upon the declaration of such dividend or the
making of such other distribution or the date of the granting of such right
of subscription or purchase, as the case may be, and, in each such case, the
number of Common Shares into which shares of Series B Preferred Stock may be
converted shall be increased in proportion to the increase (through such
dividend or distribution) in the number of outstanding Common Shares, by
reducing the Series B Conversion Price in the same proportion.

       (e)    CERTAIN ISSUES OF COMMON SHARES EXCEPTED.  Anything herein to the
contrary notwithstanding, the Corporation shall not be required to make any
adjustment of the Series B Conversion Price pursuant to Subsection 9(c)(iii)(d)
in the case of the issuance of: (i) up to an aggregate of four million nine
hundred and ninety thousand (4,990,000) Common Shares (appropriately adjusted
for stock splits, dividends, consolidations, recapitalizations and similar
events), pursuant to the Corporation's 1993 Stock Option Plan, as amended; (ii)
up to an aggregate of five million six hundred eighty-six thousand, five hundred
(5,686,500) Common Shares (appropriately adjusted for stock splits, dividends,
consolidations, recapitalizations and similar events) pursuant to the exercise
of outstanding warrants; and (iii) such other securities as the holders of
sixty-six and two-thirds percent (66 2/3%) of the then outstanding shares of
Series B Preferred Stock shall agree in writing may be issued without causing an
adjustment in the Series B Conversion Price.

       (f)      SUBDIVISION OR COMBINATION OF COMMON SHARES.  In case the
Corporation shall at any time subdivide (by any stock split, stock dividend
or otherwise) its outstanding Common Shares into a greater number of shares,
without making a corresponding subdivision of the outstanding shares of
Series B Preferred Stock, then the Series B Conversion Price in effect


                                       6
<PAGE>


immediately prior to such subdivision shall be proportionately reduced.
Conversely, in case the outstanding Common Shares shall be combined into a
smaller number of shares without a corresponding adjustment to the number of
outstanding shares of Series B Preferred Stock, then the Series B Conversion
Price in effect immediately prior to such combination shall be
proportionately increased.

       (g)    OTHER DISTRIBUTIONS. If the Corporation shall declare a
distribution payable in securities of other persons (including, but not limited
to, spin-offs of a business whereby, for example, an asset of the Corporation is
contributed to a subsidiary which is spun-off to the Corporation's
shareholders), evidences of indebtedness issued by this Corporation or other
persons, assets (excluding cash dividends) or options or rights not referred to
in Subsection 9(c)(iii)(h), then, in each such case for the purpose of this
Subsection 9(c)(iii)(g), the holders of the Series B Preferred Stock shall be
entitled to a proportionate share of any such distribution as though they were
the holders of the number of Common Shares into which their shares of Series B
Preferred Stock are convertible as of the record date fixed for the
determination of the holders of Common Shares entitled to receive such
distribution.

       (h)    REORGANIZATION OR RECLASSIFICATION.  If any capital reorganization
or reclassification of the capital stock of the Corporation shall be effected in
such a way that holders of Common Shares shall be entitled to receive stock,
securities or assets with respect to or in exchange for Common Shares, then, as
a condition of such reorganization or reclassification, lawful and adequate
provisions shall be made whereby each holder of a share or shares of Series B
Preferred Stock shall thereupon have the right to receive, upon the basis and
upon the terms and conditions specified herein and in lieu of the Common Shares
immediately theretofore receivable upon the conversion of such shares of Series
B Preferred Stock, such shares of stock, securities or assets as may be issued
or payable with respect to or in exchange for a number of outstanding shares of
such Series B Preferred Stock equal to the number of Common Shares immediately
theretofore receivable upon such conversion had such reorganization or
reclassification not taken place, and in any such case appropriate provisions
shall be made  with respect to the rights and interests of such holder to the
end that the provisions hereof shall thereafter be applicable, as nearly as may
be, in relation to any shares of stock, securities or assets thereafter
deliverable upon the exercise of such conversion rights.

       (i)    NOTICE OF ADJUSTMENT.  Upon any adjustment of the Series B
Conversion Price, then, and in each such case, the Corporation shall give
written notice thereof as soon as practicable thereafter, by first class,
registered or certified mail, postage prepaid, return receipt requested, or by
telecopier (to be promptly followed by notice sent by registered or certified
mail, return receipt requested, as set forth above), addressed to each holder of
shares of Series B Preferred Stock, as the case may be, at the address of such
holder as shown on the books of the Corporation, which notice shall state the
conversion rate resulting from such adjustment and the manner in which such
calculation was made.

       (j)    SHARES TO BE RESERVED.  The Corporation will at all times reserve
and keep available out of its authorized, but unissued, Common Shares, solely
for the purpose of issuance upon the conversion of Series B Preferred Stock as
herein provided, such number of Common Shares as shall then be issuable upon the
conversion of all outstanding shares of Series B Preferred Stock.  The
Corporation covenants that all Common Shares which shall be so issued


                                       7
<PAGE>


shall be duly and validly issued, fully paid, nonassessable and free from all
taxes, liens and charges with respect to the issue thereof.  The Corporation
will take such action as may be necessary to assure that all Common Shares
may be so issued without violation of any applicable law or regulation, or of
any requirement of any securities exchange upon which the Common Shares may
be listed.

       (k)    ISSUE TAX.  The issuance of certificates for Common Shares upon
conversion of Series B Preferred Stock shall be made without charge to the
holders thereof for any issuance tax in respect thereof, provided that the
Corporation shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of any certificate in a
name other than that of the holder (or its affiliate) of the Series B Preferred
Stock.

(iv)   VOTING.

       (a)    SHAREHOLDER VOTING.  Holders of the outstanding Series B Preferred
Stock shall be entitled to cast, on all matters submitted to a vote of all of
the shareholders of the Corporation (including in the election of directors,
except as set forth in Subsections 9(b)(iv) and 9(b)(v)) and on which
shareholders are entitled to vote under the provisions of the Wyoming Business
Corporation Act, that number of votes equal to the number of Common Shares into
which such outstanding Series B Preferred Stock is then convertible under
Subsection 9(c)(iii) at the record date for the determination of shareholders
entitled to vote on such matter, and with respect to such vote, shall be
entitled, notwithstanding any provision hereof, to notice of any stockholders'
meeting in accordance with the Bylaws of this Corporation.  Fractional votes
shall not, however, be permitted and any fractional voting rights resulting from
the aforementioned formula (after aggregating all shares into which shares of
Series B Preferred Stock held by each holder could be converted) shall be
rounded to the nearest whole number (with one-half rounded upward to one).  In
addition to their right to elect the Series B Director, as provided below, and
except as set forth in Subsections 9(b)(iv) and 9(b)(v), holders of Series B
Preferred Stock shall vote together with the holders of Series A Preferred Stock
and Common Shares on all such matters except as otherwise provided herein.

       (b)    SERIES B DIRECTOR.

              (1)    Upon the issuance of Series B Preferred Stock, the
Corporation shall name to its Board of Directors a director identified to it by
Larry Gordon, the Series B Preferred Stock representative; provided that such
director is reasonably acceptable to the Corporation.  Thereafter, and for so
long as more than fifty percent (50%) of all shares of Series B Preferred Stock
issued by the Corporation shall be outstanding, the holders of the Series B
Preferred Stock, voting as a separate voting group, shall be entitled to elect
one (1) director to the Corporation's Board of Directors ("Series B Director")
at the annual meeting of the Corporation's shareholders and otherwise if there
is a vacancy of the directorship held by the Series B Director.  If the
aforementioned minimum outstanding shares requirement has been met, then at any
meeting held for the purpose of electing directors, the presence in person or by
proxy of the holders of a majority of the outstanding shares of Series B
Preferred Stock shall constitute a quorum of such shares for the election of the
director to be elected.

              (2)    Except as otherwise provided by law, the Series B Director
shall be


                                       8
<PAGE>


elected by a majority of the votes cast by the Series B Preferred Stock at a
meeting of shareholders at which a quorum is present.  Provided that the
minimum outstanding shares requirement in Subsection 9(c)(iv)(b)(1) is met,
any vacancy in any directorship elected by the holders of Series B Preferred
Stock shall be filled only by the vote or written consent of the holders of a
majority of the then outstanding shares of Series B Preferred Stock.  Any
director who shall have been elected by the holders of Series B Preferred
Stock may be removed from office, whether with or without cause, only by the
vote or written consent of the holders of a majority of the then outstanding
shares of Series B Preferred Stock.

       (c)    NONCOMPLIANCE.  If the Corporation fails to comply with
Subsections 9(c)(iv)(b), then, in addition to any other legal remedies available
to the holders of the Series B Preferred Stock, the number of directors that the
holders of the then outstanding shares of Series B Preferred Stock shall be
entitled to elect under Subsection 9(c)(iv)(b) shall be increased to a total of
three (3) directors, effective immediately upon such noncompliance and for as
long as such noncompliance exists.

(v)    RESTRICTIONS.  For so long as more than fifty percent (50%) of all shares
of Series B Preferred Stock issued by the Corporation shall be outstanding,
except where the vote or written consent of the holders of a greater number of
shares of the Corporation is required by law or by the Articles of
Incorporation, and in addition to any other vote required by law or the Articles
of Incorporation, the Corporation will not take any of the following actions
without the approval of the holders of at least sixty-six and two-thirds percent
(66 2/3%) of the then outstanding shares of Series B Preferred Stock, given in
writing or by vote at a meeting, consenting or voting (as the case may be) as a
separate voting group:

       (a)    Engage in any transaction resulting in a "Change of Control
("Change in Control" shall mean and occur when (i) any "person" as such term is
defined in Section 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), other than a trustee or other fiduciary holding
securities under an employee benefit plan of the Corporation, is or becomes a
beneficial owner (within the meaning of rule 13d-3 promulgated under the
Exchange Act), directly or indirectly, of securities of the Corporation,
representing fifty-one percent (51%) or more of the combined voting power of the
Corporation's then outstanding securities; or (ii) the shareholders of the
Corporation approve a reorganization, merger or consolidation of the Corporation
with any other corporation or entity, other than a reorganization, merger or
consolidation which would result in the voting securities of the Corporation
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) at least fifty-one percent (51%) of the combined voting power
of the voting securities of the Corporation or such surviving entity outstanding
immediately after such reorganization, merger or consolidation; or (iii) the
shareholders of the Corporation approve a plan of complete liquidation,
dissolution or winding up of the Corporation or an agreement for the sale or
disposition by the Corporation of all or substantially all of its assets);

       (b)    Pay or declare any dividends or make any distribution with respect
to any holder of Common or Preferred Shares junior to the Series B Preferred
Stock ;


                                       9
<PAGE>


       (c)    Redeem or otherwise repurchase any shares of Common or Preferred
Shares junior to the Series B Preferred Stock; or

       (d)    Enter into any transactions with any of its affiliates, unless
each such transaction is on terms at least as favorable as those available to
the Corporation from disinterested third parties and such transaction is
approved by the Board of Directors, including the Series B Director (provided
that the Series B Director is not an interested party in such transaction); or

       (e)    Unless approved by the Board of Directors and the Series B
Director, (i) increase the number of Common Shares available under the
Corporation's 1993 Stock Option Plan, as amended, by more than an aggregate of
three million (3,000,000) Common Shares (appropriately adjusted for stock
splits, dividends, consolidations, recapitalizations and similar events); (ii)
issue or grant more than an aggregate of five million six hundred eighty-five
thousand, five hundred (5,685,500) Common Shares (appropriately adjusted for
stock splits, dividends, consolidations, recapitalizations and similar events)
pursuant to the exercise of outstanding warrants; and (iii) issue or grant other
rights to purchase Common Shares, pursuant to an employment compensation plan.

(vi)   SINKING FUND.  There shall be no sinking fund provision for the payment
of dividends, liquidation preferences, or redemption of the shares of Series B
Preferred Stock.

(vii)  REDEMPTION OF SERIES B PREFERRED STOCK.

       (a)    MANDATORY REDEMPTION.  If a Change of Control (as defined in
Subsection 9(c)(v)(a)) has occurred, the Corporation shall offer to redeem
all of the outstanding shares of Series B Preferred Stock for cash, at a
price per share equal to one hundred and fifty percent (150%) of the
liquidation preference for Series B Preferred Stock under Subsection
9(c)(ii)(a), plus any declared, but unpaid, dividends under Subsection
9(c)(i), by providing each holder of Series B Preferred Stock with written
notice of such redemption ("Redemption Offer Notice") within thirty (30) days
of such Change of Control. If any holder of Series B Preferred Stock does not
elect in writing within twenty (20) days of the date of the Redemption Offer
Notice ("Election Period") to have all of such holder's shares of Series B
Preferred Stock redeemed, then, with respect to the holder's unredeemed
shares of Series B Preferred Stock, such holder's mandatory redemption rights
hereunder shall terminate as to such Change of Control event.  If any of the
holders of the outstanding shares of Series B Preferred Stock elects
redemption before the expiration of the Election Period, then the Corporation
shall notify such holder of the redemption within ten (10) days following the
end of the Election Period ("Mandatory Redemption Notice").  Within ten (10)
days of the receipt of the Mandatory Redemption Notice, such holder shall
surrender to the Corporation the certificate(s) representing such shares of
Series B Preferred Stock to be redeemed duly endorsed for transfer to this
Corporation, and upon receipt of such certificates, the Corporation shall pay
the redemption price for such shares to the order of the person whose name
appears on such certificate(s) as the owner thereof, and each surrendered
certificate shall be cancelled.  As to any portion of the shares of Series B
Preferred Stock so surrendered which are not subject to such holder's
redemption election, the Corporation shall promptly issue to the person whose
name appears on such certificate(s) a certificate in due and proper form
representing the shares of Series B Preferred Stock which have not been
redeemed.  When the redemption price is paid, all rights in respect of the


                                       10
<PAGE>


redeemed shares of Series B Preferred Stock shall cease and terminate, and
such shares shall no longer be deemed to be outstanding, whether or not the
certificates representing such shares have been received by the Corporation.

       (b)    OPTIONAL REDEMPTION.  If from and after one year of the date the
first share of Series B Preferred Stock is sold and issued by the Corporation,
the Common Shares shall have traded above seventy-five cents ($0.75) per share
(as adjusted for stock splits, dividends, consolidations, recapitalizations and
similar events) for sixty (60) consecutive days on a national securities
exchange or NASDAQ, or the closing bid price quoted by an established quotation
service for over-the-counter securities shall be above seventy-five cents
($0.75) for sixty (60) consecutive days, then the Corporation shall have the
right, but not the obligation, to redeem all of the outstanding shares of Series
B Preferred Stock for cash, at a price per share equal to one hundred and fifty
percent (150%) of the liquidation preference for Series B Preferred Stock under
Subsection 9(c)(ii)(a), plus any declared, but unpaid, dividends under
Subsection 9(c)(i), by providing each holder of Series B Preferred Stock with
written notice of such redemption not less than thirty (30) days prior to the
scheduled date of redemption ("Optional Redemption Notice").  In the event of
such redemption, and prior to the scheduled date of redemption, holders of
Series B Preferred Stock shall surrender to the Corporation the certificate(s)
representing such shares of Series B Preferred Stock to be redeemed duly
endorsed for transfer to this Corporation, and upon receipt of such
certificates, the Corporation shall pay the redemption price for such shares to
the order of the person whose name appears on such certificate(s) as the owner
thereof, and each surrendered certificate shall be cancelled.  When the
redemption price is paid, all rights in respect of redeemed shares of Series B
Preferred Stock shall cease and terminate, and such shares shall no longer be
deemed to be outstanding, whether or not the certificates representing such
shares have been received by the Corporation.  Nothing herein contained in this
Subsection 9(c)(vii)(b) shall prohibit any holder of Series B Preferred Stock
from electing the benefits of the provisions of Subsection 9(c)(iii) or other
applicable conversion provisions prior to the scheduled date of redemption.

       (c)    NONCOMPLIANCE/CONVERSION PRICE ADJUSTMENT.  If (i) any of the
holders of Series B Preferred Stock elects redemption under Subsection
9(c)(vii)(a) and complies with the provisions therein; and (ii) the Corporation
fails to redeem any of such holder's shares of Series B Preferred Stock as
required therein, then the Series B Conversion Price for those unredeemed shares
of Series B Preferred Stock shall be reduced by one percent (1%) on the seventh
(7th) day following such noncompliance and by an additional one percent (1%)
every seven (7) days thereafter until the redemption has been made.

(viii) NONCOMPLIANCE WITH REGISTRATION RIGHTS/CONVERSION PRICE ADJUSTMENT.  If
all of the conditions set forth in Section 5.1 of that certain Investor Rights
Agreement between the Corporation and the holders of Series B Preferred Stock
have been met and the Corporation fails to comply with the registration rights
provisions set forth in such Section 5.1, then the Series B Conversion Price for
those shares of Series B Preferred Stock which the Corporation has failed to
register shall be reduced by one percent (1%) on the seventh (7th) day following
such noncompliance and by an additional one percent (1%) every seven (7) days
thereafter until the registration of such shares has been made.

"PURCHASERS" and individually as a "PURCHASER".

                                      RECITALS

     WHEREAS, the Purchasers desire to purchase, and the Company agrees to sell,
shares of the Company's Series B Preferred Stock (the "SERIES B PREFERRED") and
warrants to purchase shares of Common Stock of the Company (the "Warrants")
pursuant to the terms and conditions of this Agreement.

     WHEREAS, in connection with the foregoing transactions, certain of the
parties hereto shall enter into the Investor Rights Agreement, attached hereto
as EXHIBIT D (the "RIGHTS AGREEMENT"), providing for certain registration
rights.

     NOW, THEREFORE, in consideration of the mutual promises contained herein
and made pursuant hereto, and good and available consideration, receipt of which
is hereby acknowledged, the parties hereto do hereby agree as follows:

1.   AUTHORIZATION AND SALE OF SHARES AND WARRANTS

     1.1. AUTHORIZATION OF THE SHARES AND WARRANTS.  The Company has, or before
the Closing (as defined in SECTION 2.1 below) will have, authorized (i) the sale
and issuance of up to 8,425,000 shares of its Series B Preferred (the "SHARES");
(ii) the issuance of such shares of Common Stock to be issued upon conversion of
the Shares (the "CONVERSION SHARES"); (iii) the issuance of Warrants to purchase
3,622,750 shares of Common Stock of the Company and the underlying shares of
Common Stock to the Purchasers; and (iv) the issuance of 498,750 Warrants and

Shares shall have the rights, restrictions, privileges and preferences as set
forth in the Company's Articles of Amendment attached hereto as EXHIBIT B (the
"ARTICLES OF AMENDMENT").

     1.2  SALE OF THE SHARES.  Subject to the terms and conditions hereof and in
reliance upon the representations, warranties and agreements contained herein,
the Company will issue and sell to each Purchaser, severally and not jointly,
and each Purchaser will purchase from the Company, severally and not jointly, at
the applicable Closing, the number of Shares set forth

opposite the Purchaser's name on the Schedule of Purchasers, at a purchase
price of NINETEEN CENTS ($0.19) per Share.

     1.3  ISSUANCE OF WARRANTS. The Company agrees to issue, at the Closing, to
each Purchaser 43 Warrants to purchase one share of Common Stock of the Company
for each 100 Shares purchased by the Purchaser.  This price per Warrant shall be

the Closing the Company shall also issue an aggregate of 498,750 Warrants to

security independently.

2.   CLOSING DATE; DELIVERY

     2.1  CLOSING DATE.  The closing of the purchase and sale of the Shares
hereunder (the "CLOSING") shall be held at the offices of the Company or their

place as shall be mutually agreed upon by the Company and the Purchasers.

amount of the purchase price of the Shares to be purchased by a Purchaser, the
Company shall deliver to such Purchaser a certificate, registered in the
Purchaser's name as set forth on the Schedule of Purchasers, representing the
number of Shares that the Purchaser is purchasing from the Company and Warrants
as required pursuant to this Agreement.

3.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     As used herein, the term: "to the best knowledge of the Company" (or words
to that effect) shall mean such knowledge and belief as may be acquired after
reasonable inquiry of the directors, officers, and employees of the Company.
Except as set forth in EXHIBIT C attached hereto (the "SCHEDULE OF EXCEPTIONS"),
the Company hereby represents and warrants to each Purchaser as follows:

     3.1  ORGANIZATION AND STANDING; ARTICLES AND BYLAWS.  The Company is a

to carry on its business as presently conducted and as proposed to be conducted.
The Company is duly qualified to do business as a foreign corporation in each
jurisdiction in which the conduct of its business requires such qualification,
except where the failure to so qualify would not have a material adverse effect
on the Company's business as presently conducted and as currently proposed to be
conducted.  The Company has made available to the Purchasers copies of its
Secretary's Certificate, which includes true, correct and complete copies of its
Articles of Continuance and Bylaws, as presently in effect.

Agreement and the Articles of Amendment and the Warrants.

     3.3  SUBSIDIARIES.  Other than the entities listed on paragraph 3.3 of the

               capital stock will consist of (a) 90,000,000 shares of common
               stock (the "COMMON STOCK"), of which 35,459,423 shares will be
               issued and outstanding, and (b) 10,000,000 shares of preferred
               stock, of which 0 shares of Series A Preferred Stock are
               outstanding and 8,425,000 shares have been designated as "Series
               B Preferred Stock", none of which will be issued or outstanding
               immediately prior to the Closing. The Series B Preferred is
               referred to herein as "PREFERRED STOCK" or the "SERIES B
               PREFERRED STOCK".  Of the authorized, but unissued, Common Stock,
               0 shares are reserved for issuance upon the conversion of the
               Series A Preferred Stock, 5,686,500 are reserved for issuance
               upon exercise of outstanding warrants, and 4,990,000 shares are

               (the "Plan").

     The issued and outstanding shares of Common Stock of the Company are duly
and validly issued, fully paid and nonassessable, and such shares, and all

               Warrants (and the Common Stock issuable upon conversion or
               exercise thereof) constitutes or will constitute an event, under
               any capital stock or convertible security or any anti-dilution or
               similar provision of any


                                      3

<PAGE>

               agreement or instrument to which the Company is a party or by
               which it is bound or affected, which shall either increase the
               number of shares or units of capital stock issuable upon
               conversion of any securities or upon exercise of any warrant or
               right to subscribe to or purchase any stock or similar security,
               or decrease the consideration per share or unit of capital stock
               to be received by the Company upon such conversion or exercise.

     3.5  AUTHORIZATION.  All corporate action on the part of the Company, its
directors, officers and shareholders necessary for the authorization, execution,
delivery and performance by the Company of this Agreement, the Rights Agreement,
and the Articles of Amendment, the Warrants and the consummation of the
transactions contemplated herein and therein, and for the authorization,
issuance, sale and delivery of the Shares and the Conversion Shares and shares
of Common Stock to be issued upon exercise of the Warrants has been taken or
will be taken prior to the Closing.  This Agreement and the Rights Agreement and

laws of general application affecting enforcement of creditors' rights
generally, including rules of law governing specific performance, injunctive
relief or other equitable remedies; and the effect of public policy on the
indemnification provisions set forth in the Rights Agreement.  Except as set
forth in the Schedule of Exceptions, the Shares are not subject to any
preemptive rights or rights of first refusal.  The Shares, when issued in
compliance with the provisions of this Agreement, will be validly issued, fully
paid and nonassessable and issued in compliance with all applicable federal and
state securities laws (based in part upon the representation of the Purchasers
contained herein), will be free of any liens or encumbrances, and will be free
of restrictions on transfer other than under this Agreement, the Rights
Agreement and state and/or federal securities laws.  The Conversion Shares and

contracts and commitments incurred in the ordinary course of business and not
required under generally accepted accounting principles to be reflected in

aggregate, are not material to the financial condition or operating results
of the Company.  Except as disclosed in the Financial Statements, the Company

                ordinary course of business, none of which individually or in

                or payment of any obligation by the Company, except in the
                ordinary course of business and that is not material to the
                assets, properties, financial condition, operating results or
                business of the Company (as such business is presently conducted
                and as it is proposed to be conducted);

          v.    any material adverse change or amendment to a material contract
                or arrangement by which the Company or any of its assets or
                properties is bound or subject;

                due or payable;

          xi.   any loans or guarantees made by the Company to or for the
                benefit of its shareholders, employees, officers or directors,
                or any members of their immediate families, other than travel
                advances and other advances made in the ordinary course of its
                business;

          xii.  any declaration, setting aside or payment or other distribution

former employees or their obligations under any agreements with prior employers.
The Company is not a party or subject to the provisions of any order, writ,
injunction, judgment or decree of any court or governmental agency or
instrumentality.  There is no action, suit, proceeding, or investigation by the
Company currently pending or that the Company intends to initiate.

     3.9  CONSENTS.  Except as set forth in the Schedule of Exceptions, no

reasonable terms, any additional rights necessary or required for its business
as presently proposed to be conducted without, except in the case of patents and

of any other person or entity.  To the best knowledge of the Company, none of
its employees is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
the use of his or her best efforts to promote the interests of the Company or
that would conflict with the Company's business as proposed to be conducted.
Neither the execution nor delivery of this Agreement, the Articles of Amendment
or the Rights Agreement or the Warrants nor the carrying on of the Company's
business by the employees of the Company nor the conduct of the Company's
business as proposed, will, to the best of the Company's knowledge, conflict
with or result in a breach of the terms, conditions or provisions of, or
constitute a default under, any contract, covenant or instrument under which any
of such employees is now obligated.  The Company does not believe nor does it
have any reason to believe it is or will be necessary to utilize any inventions
of any of its employees (or people they currently intend to hire) made prior to
the employment of any such person by the Company.  Since its organization, the
Company has


                                      7

taken reasonable security measures to protect the secrecy, confidentiality

known by competitors.

     3.12 OFFERING.  Subject to the truth and accuracy of each Purchaser's
representations set forth in this Agreement, the offer, sale and issuance of the
Shares and Warrants as contemplated by this Agreement are exempt from the
registration requirements of the Act, and from the qualification requirements of
the California Corporate Securities Law of 1968, as amended, and of such other
states as may have jurisdiction over these transactions.

     3.13 COMPLIANCE WITH OTHER INSTRUMENTS.  The Company is not in any
violation or default of any term of the Articles of Amendment pertaining to its

Incorporation, or its Bylaws, any material term of any material agreement to
which the Company is a party, including its existing debt instruments, or any
judgment, decree, order, statute, rule or regulation to which the Company is
subject, that alone or in the aggregate would have a material adverse effect on
the condition, financial or otherwise, or operations of the Company.  Except as
set forth in the Schedule of Exceptions, the issuance of the Shares does not
require the vote, approval or consent of the Company's shareholders or of the
Series A Preferred shareholders or of any other party.  The execution, delivery
and performance of this Agreement, the Rights Agreement and the Articles of
Amendment, and Warrants and the consummation of the transactions contemplated
hereby and thereby have not resulted and will not result in any violation or be
in conflict with or constitute, with or without the passage of time and giving
of notice, either a default under any such provision, instrument, judgment,
order, writ, decree or contract or an event that results in the creation of any
lien, charge or encumbrance upon any assets of the Company or the suspension,
revocation, impairment, forfeiture, or nonrenewal of any material permit,
license, authorization, or approval applicable to the Company, its business or
operations or any of its assets or properties.  The Company has avoided every
condition, and has not performed any act, the occurrence of which would result
in the Company's loss of any rights granted under any license, distribution or
other agreement.

     3.14 EMPLOYEES.  To the best of the Company's knowledge, no employee of the
Company is in violation of any term of any employment contract, patent
disclosure agreement, non-competition agreement, or any restrictive covenant to
a former employer relating to the right of any such employee to be employed by
the Company because of the nature of the business conducted or presently
proposed to be conducted by the Company.

     3.15 CONFIDENTIAL INFORMATION AND INVENTION ASSIGNMENT AGREEMENTS. The
Company has entered into a confidentiality agreement in a form previously
provided to the Purchasers' legal counsel with each officer, director, and key
employee of the Company.  All persons having access to the Company's Proprietary
Information have executed and are bound by confidentiality agreements.  The
Company, after reasonable investigation, is not aware that any of its employees,
officers or consultants are in violation thereof, and the Company will use its
best efforts to prevent any such violation.

4.   REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

     Each Purchaser hereby represents and warrants, severally and not jointly,
to the Company as follows:

     4.1  NO REGISTRATION.  Purchaser understands that the Shares, Conversion
Shares, Warrants and the underlying shares of Common Stock have not been
registered under the Act (as defined in SECTION 3.4 above) and are being offered
and sold pursuant to an exemption from registration contained in the Act based
in part upon the representations of each Purchaser below or otherwise made
hereunder.

     4.2  INVESTMENT EXPERIENCE.  Purchaser or its professional advisor has
substantial experience in evaluating and investing in private placement
transactions of securities in companies similar to the Company, and is capable
of evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests.  Purchaser is an Accredited Investor as
set forth in the Subscription Agreement.  Purchaser represents that it has not
been organized for the purpose of acquiring the Shares, Common Shares, Warrants,
or underlying shares of Common Stock, unless the beneficial owners are
accredited investors.

     4.3  ACCESS TO INFORMATION.  Purchaser has had full opportunity to ask
questions and receive answers concerning the terms and conditions of the
offering of the Shares and the Warrants and has had full access to the Company's
officers and such other information concerning the Company as it has requested,
and has read the Disclosure Documents and understands the risk factors set forth
therein.

     4.4  INVESTMENT.  Purchaser is acquiring the Shares to be issued and sold
hereunder (and the Conversion Shares, Warrants and underlying shares of Common
Stock) for investment in its own account (or a trust account if Purchaser is a
trustee), and not as a nominee or agent (except in the case of a Custodian for a
minor), and not with a view to or for sale in connection with the distribution
thereof.  Purchaser understands that it must bear the economic risk of this
investment indefinitely unless the Shares or the Conversion Shares or the shares
of Common Stock underlying the Warrants are registered pursuant to the Act, or
an exemption from such registration is available.  Purchaser further understands
that there is no assurance that any exemption from the Act will be available or,
if available, that such exemption will allow Purchaser to dispose of or
otherwise transfer any or all of the Shares, the Conversion Shares or


                                      12

<PAGE>

the shares of Common Stock underlying the Warrants under the circumstances in
the amounts or at the times Purchaser might propose.

     4.5  AUTHORIZATION.  Purchaser has the full power, right and authority to
execute and deliver this Agreement and the Rights Agreement, and to perform its
obligations hereunder and thereunder.  This Agreement and the Rights Agreement,
when executed by Purchaser, will constitute valid and legally binding
obligations of Purchaser, enforceable in accordance with their terms, subject to
laws of general application relating to bankruptcy, insolvency, and the relief
of debtors, and rules of law governing specific performance, injunctive relief
and other equitable remedies.  No consent, approval, authorization, order,
filing, registration or qualification of or with any court, governmental
authority or third person is required to be obtained by Purchaser in connection
with the execution and delivery of this Agreement and the Rights Agreement or
the performance of Purchaser's obligations hereunder.  The execution, delivery
and performance of this Agreement and the Rights Agreement and the consummation
of the transactions contemplated herein and therein (including ownership of the
Shares, the Conversion Shares, the Warrants and the shares of Common  Stock
underlying the Warrants) by the Purchaser do not violate any provision of, or
constitute, with or without the passage of time or the giving of notice, a
material breach of or default under, any term, condition or provision of any
agreement, indenture or other instrument to which the Purchaser is a party, or
by which it or its properties or assets are bound, or of any order, judgment or
decree against or binding upon the Purchaser.

     4.6  TAX ADVISORS.  Purchaser has reviewed with its own tax advisors the
federal, state and local tax consequences of this investment, where applicable,
and the transactions contemplated by this Agreement.  Purchaser is relying
solely on such advisors and not on any statements or representations of the
Company or any of its agents and understands that Purchaser (and not the
Company) shall be responsible for Purchaser's own tax liability that may arise
as a result of this investment or the transactions contemplated by this
Agreement.

     4.7  PURCHASER'S COUNSEL.  Purchaser acknowledges that it has had the
opportunity to review this Agreement, the exhibits and the schedules attached
hereto and the transactions contemplated by this Agreement with its own legal
counsel.

     4.8  RESALE UNDER RULE 144.  Purchaser acknowledges that it is aware of
Rule 144 promulgated under the Act, which permits limited public resales of
securities acquired in a nonpublic offering, subject to the satisfaction of
certain conditions.  Purchaser understands that under Rule 144, except as
otherwise provided by section (k) of that Rule, the conditions include, among
other things: the availability of certain current public information about the
issuer, the resale occurring not less than one year after the party has
purchased and paid for the securities to be sold, and limitations on the amount
of securities to be sold and the manner of sale.  Purchaser acknowledges that,
in the event all of the requirements of Rule 144 are not met, registration under
the Act, compliance with the SEC's Regulation A or an exemption from
registration will be required for any disposition of the Shares and the Common
Stock issued on conversion thereof or the Warrants and shares underlying the
Warrants.  Purchaser understands that, although Rule 144 is not exclusive, the
SEC has expressed its opinion that persons proposing


                                      13

<PAGE>

to sell restricted securities received in a private offering other than in a
registered offering or pursuant to Rule 144 will have a substantial burden of
proof in establishing that an exemption from registration is available for
such offers or sales and that such persons do so at their own risk.

     4.9  RESIDENCY.  The residency of Purchaser (or, in the case of a
partnership or corporation, such entity's principal place of business) is
correctly set forth on EXHIBIT A.

     4.10 LEGEND.  It is understood that the certificates evidencing the Shares,

     8.1  GOVERNING LAW.  This Agreement will be interpreted and governed by the
laws of the State of California, except that the Articles of Amendment shall
comply with Wyoming law.

     8.2  VENUE; JURISDICTION.  With respect to any disputes arising out of or
related to this Agreement, the parties consent to the non-exclusive personal
jurisdiction of, and venue in, the state courts of Los Angeles County,
California (or in the event of exclusive federal jurisdiction, the courts of the

     8.3  SUCCESSORS AND ASSIGNS.  The provisions hereof shall inure to the
benefit of, and be binding upon, the successors, assigns, heirs, executors and
administrators of the parties hereto.

     8.4  MODIFICATIONS.  No amendment or modification of this Agreement will be

percent (51%) or more of the Shares sold under this Agreement.  Notwithstanding
the foregoing, in no event shall (i) the obligation of a Purchaser to purchase

     8.5  NOTICES.  All notices and other communications required or permitted
hereunder shall be in writing and shall be mailed by first-class mail, postage
prepaid, or delivered either by hand or by messenger, addressed (a) if to a
Purchaser, as indicated on the Schedule of Purchasers, or at such other address
as Purchaser shall have furnished to the Company in writing, or (b) if to any
other holder of any Shares or any Common Stock issued upon conversion of Shares,
or exercise of Warrants, at such address as such holder shall have furnished the
Company in writing or, until any such holder so furnishes an address to the
Company, then to and at the address of the last holder thereof who has so
furnished an address to the Company, or (c) if to the Company, at its address
set forth at the end of this Agreement or at such other address as the Company
shall have furnished to the Purchasers and each such other holder in writing.

     8.6  DELAYS OR OMISSIONS.  No delay or omission to exercise any right,
power or remedy accruing to any holder of any Shares upon any breach or default
of the Company under this Agreement shall impair any such right, power or remedy
of such holder, nor shall it be construed to be a waiver of any such breach or
default or an acquiescence therein, or of or in any similar breach or default
thereafter occurring; nor shall any waiver of any single breach or default be
deemed a waiver of any other breach or default theretofore or thereafter
occurring.  Any waiver, permit, consent or approval of any kind or character on
the part of any holder of any breach or default under this Agreement, or any
waiver on the part of any holder of any provisions or conditions of this
Agreement, must be made in writing and shall be effective only to the extent
specifically set forth in such writing.  All remedies, either under this
Agreement or by law or otherwise afforded to any holder, shall be cumulative and
not alternative.

     8.7  RIGHTS; SEPARABILITY; SEVERABILITY.  Unless otherwise expressly
provided herein, the rights of Purchasers hereunder are several rights, not
rights jointly held with any of the other Purchasers.  In case any provision of
the Agreement shall be invalid, illegal or unenforceable by a court of competent
jurisdiction, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby, and the parties
agree to negotiate, in good faith, a legal and enforceable substitute provision
which most nearly effects the parties' intent in entering into this Agreement.
As a remedy at law will be inadequate, the Purchasers shall be entitled to
injunctive relief to enforce this Agreement and the ancillary agreements
executed pursuant hereto and the provisions of the Articles of Amendment.

     8.8  TITLES AND SUBTITLES.  The titles of the paragraphs and subparagraphs

Purchaser for any losses incurred by such Purchaser in connection with its
investment in the Company.

     8.15 LIKE TREATMENT OF HOLDERS.  Neither the Company nor any of its
affiliates shall, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee, payment for the redemptions or
exchange of the Shares, or otherwise, to any holder of Shares for or as an
inducement to, or in connection with solicitation of, any consent, waiver or
amendment of any terms or provisions of the Shares or this Agreement, the Rights
Agreement, unless such consideration is paid to all holders of the Shares bound
by such consent, waiver or amendment, whether or not such holders so consent,
waive or agree to amend and whether or not such holders tender their Shares for
redemption or exchange.

Corporation Act ("Act"), the Board of Directors of Soligen Technologies, Inc. a
Wyoming corporation by continuation, hereby adopts these Articles of Amendment
on behalf of the Corporation, effective without shareholder action.  The
Corporation's Articles of Continuance were filed with the Wyoming Secretary of
State on April 13, 1993 ("Articles of Continuance").

     A.   The name of the corporation is Soligen Technologies, Inc. (the
"Corporation").

     B.   Effective as of the date of filing of these Articles of Amendment with
the Wyoming Secretary of State, the Articles of Continuance are hereby amended
by adding a new Section 9(c) as indicated on EXHIBIT A, attached hereto and
incorporated herein by this reference.

     C.   The foregoing amendment was duly adopted by the Board of Directors of

     IN WITNESS WHEREOF, the undersigned has executed these Articles of
Amendment of the Corporation this 23rd day of November, 1999.

                             RIGHTS AND PREFERENCES OF
                                SERIES B CONVERTIBLE
                                 PREFERRED STOCK OF
                             SOLIGEN TECHNOLOGIES, INC.


       9 (c)  The Series B Convertible Preferred Stock ("Series B Preferred
Stock") shall consist of eight million four hundred twenty-five thousand
(8,425,000) shares having the following particular rights and preferences:

(i)    DIVIDENDS.  Holders of shares of Series B Preferred Stock shall not be
entitled to any fixed or guaranteed dividends, nor to any cumulative dividend
rights, but shall be entitled to receive out of the earnings and assets of the
Corporation only such dividends as may be lawfully declared on such dates or may
be determined in the discretion of the Board of Directors.  No dividend or other
distribution whatsoever shall be declared or paid on Common Shares or Preferred
Shares ranking junior to the rights of the Series B Preferred Stock unless a
dividend or other distribution shall be simultaneously paid on each outstanding
share of Series B Preferred Stock which is equal to or greater than the product
of (i) the dividend or distribution proposed to be declared or paid on each
share of Common Shares or such junior Preferred Shares (on an as-converted to
Common Shares basis) times (ii) the number of Common Shares into which each such
share of Series B Preferred Stock is then convertible under Subsection 9(c)(iii)
below.  In any event, no dividend or other distribution shall be paid at any
time on Series B Preferred Stock, on any other class or series of Preferred
Shares, or on Common Shares which would have the effect of reducing the net
assets of the Corporation below the aggregate preferential amount (determined in
accordance with Subsection 9(c)(ii) below) payable to holders of Series B
Preferred Stock upon liquidation or dissolution of the Corporation.

(ii)   LIQUIDATION.

       (a)    LIQUIDATION PREFERENCES.  Upon liquidation or dissolution of the
Corporation, whether voluntary or involuntary, each share of Series B Preferred
Stock shall entitle its holder to receive, out of the assets of the Corporation
available for distribution to shareholders, whether from capital, surplus or
earnings, and before any distribution of such assets to the holders of Common
Shares or Preferred Shares ranking junior to the rights of the Series B
Preferred Stock, a liquidation preference of twenty cents ($0.20) per share (as
adjusted for stock splits, dividends, consolidations, recapitalizations and
similar events), plus any unpaid dividends declared pursuant to Subsection
9(c)(i) above.  If the assets of the Corporation available for distribution to
shareholders are insufficient to satisfy in full the liquidation preferences for
Series B Preferred Stock and all the other classes or series of Preferred Shares
entitled to a stated liquidation preference, then the holders of Series A and
Series B Preferred Stock shall share ratably in such distribution in proportion
to their respective stated liquidation preferences, and within each such series,
each holder shall be entitled to receive the same distribution for each share of
such series.


                                      27

<PAGE>

After setting apart or paying in full the liquidation preferences on Series A
and Series B Preferred Stock, further distribution of the remaining available
assets shall be made pro rata to the holders of any other classes or series
of Preferred Shares entitled to a stated preference on liquidation, and then
pro rata to the holders of Common Shares.

       (b)    DEEMED LIQUIDATIONS.  The sale of all or substantially all of the
Corporation's assets, or the acquisition of the Corporation by another entity by
means of merger, consolidation, share exchange, reorganization or otherwise,
pursuant to which shares of the Corporation's capital stock are converted into
cash, securities or other property of the acquiring entity or any of its
affiliates, shall be regarded as a liquidation within the meaning of this
Subsection 9(c)(ii); PROVIDED, HOWEVER, that each holder of Series B Preferred
Stock shall have the right to elect the benefits of the provisions of Subsection
9(c)(iii) or other applicable conversion provisions in lieu of receiving payment
of the liquidation preference in the event of the liquidation, dissolution or
winding up of the Corporation pursuant to this Subsection 9(c)(ii); PROVIDED,
FURTHER, that this provision shall not apply if the holders of the Corporation's
voting capital stock immediately prior to such merger, consolidation, share
exchange or reorganization beneficially own, directly or indirectly, more than
fifty percent (50%) of the combined voting power of the capital stock of the
corporation resulting from such merger, consolidation, share exchange or
reorganization.

       (c)    NONCASH DISTRIBUTION.  Whenever the distribution provided for in
this Subsection 9(c)(ii) shall be payable in property other than cash, the value
of such distribution shall be the fair market value of such property as
determined in good faith by the Corporation's Board of Directors.

(iii)  CONVERSION.

       (a)    AUTOMATIC CONVERSIONS.  At any time or times, part or all of any
holder's shares of Series B Preferred Stock may be converted into Common Shares
at the conversion price then in effect, in the manner specified below, and upon
delivery by the holder thereof of written notice of conversion, specifying the
number of such shares to be converted, to the Corporation at its principal
business offices (or at the office of any transfer agent for shares of Series B
Preferred Stock or Common Shares), accompanied by the certificate or
certificates for the shares to be converted, duly endorsed in blank or
accompanied by signed instruments appropriate for the transfer thereof.  In
addition, all of the outstanding shares of Series B Preferred Stock shall, at
the election of the Corporation's Board of Directors, be automatically converted
into Common Shares in the manner specified below upon the occurrence of either
of the following events (an "Automatic Conversion Event"):

              (1)    Immediately prior to such time as the Corporation shall
close a firm commitment underwritten public offering of Common Shares pursuant
to a registration statement filed pursuant to the Securities Act of 1933, as
amended, ("Securities Act") in which the Corporation receives gross proceeds of
at least ten million dollars ($10,000,000) and at a price equal to or greater
than one dollar ($1.00) per share (adjusted for stock splits, dividends,
consolidations, recapitalizations, and similar events); or


                                      28

<PAGE>

              (2)    At any such time as (a) the Common Shares shall have
traded above one dollar ($1.00) per share (as adjusted for stock splits,
dividends, consolidations, recapitalizations and similar events) for sixty
(60) consecutive trading days on a national securities exchange or NASDAQ, or
(b) the closing bid price for the Common Shares quoted by an established
quotation service for over-the-counter securities shall be above one dollar
($1.00) per share (as adjusted for stock splits, dividends, consolidations,
recapitalizations and similar events) for sixty (60) consecutive trading
days; and the cumulative trading volume of the Common Shares during such
sixty (60) consecutive trading days is equal to or greater than one million
(1,000,000) Common Shares, if traded on a national securities exchange, or
one million five hundred thousand (1,500,000) Common Shares, if traded on
NASDAQ or traded over-the-counter.

       (b)    CONVERSION PROCEDURES.  The Common Shares (or other shares,
securities or property) into which the outstanding shares of Series B
Preferred Stock are convertible as computed in this Subsection 9(c)(iii)
shall, promptly after delivery to the Corporation of written notice of any
conversion election, or promptly after the occurrence of any Automatic
Conversion Event, and upon surrender to the Corporation of the certificates
representing the Series B Preferred Stock to be converted, duly endorsed in
blank or accompanied by signed instruments appropriate for transfer, be
issued and delivered as soon as practicable to the holders of Series B
Preferred Stock in due and proper form, and shall be fully paid and
nonassessable; as to any portion of the shares so surrendered which are not
subject to such conversion election, the Corporation shall promptly issue to
the holder thereof a certificate in due and proper form representing the
shares of Series B Preferred Stock which have not been so converted.
Conversion shall be deemed to have been made at the close of business on the
date that notice of such written election was given by the holder, or on the
date that the Corporation's Board of Directors elected to declare an
Automatic Conversion Event, irrespective of the date on which such surrender
or issuance may occur, and as of such election date each such holder shall be
deemed to have become the record holder of such respective number of Common
Shares (or other shares, securities or property), and the Series B Preferred
Stock so converted shall be deemed forthwith cancelled and shall not
thereafter be deemed authorized or subject to reissuance.  No adjustment
shall be made in the number of Common Shares issuable upon conversion to
reflect declared, but unpaid, dividends on Series B Preferred Stock, but such
dividends for which the payment date has passed shall be paid in cash as of
the date of conversion of the shares of Series B Preferred Stock as to which
they are owing. The Corporation shall not be required to issue any fraction
of Common Shares upon conversion of Series B Preferred Stock; if any fraction
of Common Shares would, except for the foregoing clause, be issuable to any
holder on the conversion of Series B Preferred Stock, the Corporation shall
pay to each holder of such converted Series B Preferred Stock an amount in
cash equal to the then current fair market value of such fractional interest.

       (c)    CONVERSION RATES.  The number of Common Shares issuable with
respect to any share of Series B Preferred Stock shall be determined by dividing
twenty cents ($0.20) by the conversion price then in effect at the time of
conversion for such series (the "Series B Conversion Price"), which shall
initially be twenty cents ($0.20).


                                      29

<PAGE>

       (d)    ADJUSTMENT OF SERIES B CONVERSION PRICE UPON ISSUANCE OF COMMON
SHARES OR CONVERTIBLE SECURITIES.  Except as provided in Subsection
9(c)(iii)(e), if, after the first date that a share of Series B Preferred Stock
is issued, the Corporation shall issue or sell, or, in accordance with
Subsections 9(c)(iii)(d)(1) through 9(c)(iii)(d)(5), is deemed to have issued or
sold, any Common Shares, or any stock or security convertible into or
exchangeable for Common Shares, without consideration or for a consideration per
share less than the per-share "Fair Market Value" of the Common Shares as of the
end of the day immediately preceding such issuance or sale, or deemed issuance
or sale in accordance with Subsections 9(c)(iii)(d)(1) through 9(c)(iii)(d)(5),
then, forthwith upon each such issue or sale or deemed issuance or sale, the
Series B Conversion Price shall be reduced to the price determined by dividing
(i) an amount equal to the sum of (x) the number of Common Shares of the
Corporation outstanding immediately prior to such issue or sale (including the
number of Common Shares issuable pursuant to exercise of all outstanding options
and warrants and the conversion of all of the outstanding Preferred Shares at
the then existing conversion prices) multiplied by the then existing Series B
Conversion Price plus (y) the consideration, if any, received by the Corporation
upon such issue or sale, by (ii) the sum of the number of Common Shares
outstanding immediately after such issue or sale (including the Common Shares
issuable pursuant to conversion or exchange of the securities or stock issued or
sold in such issue or sale) plus the number of Common Shares issuable pursuant
to exercise of all outstanding options and warrants and the conversion of all of
the outstanding Preferred Shares at the conversion prices existing before such
issue or sale. "Fair Market Value" shall mean (i) if the Common Shares are
publicly traded, then (a) if the Common Shares are then traded on a national
securities exchange on the date in question, the average of the high and low
prices of the Common Shares on the principal national securities exchange on
which the Common Shares are traded; (b) if the Common Shares are then traded on
the NASDAQ National Market System on the date in question, the last reported
per-share sales price of the Common Shares on the NASDAQ National Market System;
or (c) if the Common Shares are then traded on the over-the-counter market on
the date in question, the last reported per-share sales price; PROVIDED THAT if
there have been no sales reported in the most recent two trading days at the
time of determination, then the closing bid price (or average of bid prices)
last quoted by an established quotation service for over-the-counter securities,
or (II) if the Common Shares are not publicly traded on the date in question,
then the per-share fair market value of the Common Shares as determined in good
faith by the Corporation's Board of Directors, after taking into consideration
all factors that it deems appropriate, including, without limitation, recent
sale and offer prices of the Common Shares in private transactions negotiated at
arm's length.

       For purposes of this Subsection 9(c)(iii)(d), the following Subsections
9(c)(iii)(d)(1) to 9(c)(iii)(d)(5) shall also be applicable:

              (1)    ISSUANCE OF RIGHTS OR OPTIONS.  In case at any time the
Corporation shall in any manner grant (whether directly or by assumption in a
merger or otherwise) any options, warrants or other rights to subscribe for or
to purchase Common Shares or any stock or security convertible into or
exchangeable for Common Shares (such options, warrants and rights being called
"Options" and such convertible or exchangeable stock or securities being called
"Convertible Securities") whether or not such Options or the right to convert or
exchange any


                                      30
<PAGE>

such Convertible Securities are immediately exercisable, and the
price per share for which Common Shares is issuable upon the exercise of such
Options or upon the conversion or exchange of such Convertible Securities
(determined by dividing (i) the total amount, if any, received or receivable by
the Corporation as consideration for the granting of such Options, plus the
minimum aggregate amount of additional consideration payable to the Corporation
upon the exercise of all such Options, plus, in the case of such Options which
relate to Convertible Securities, the minimum aggregate amount of additional
consideration, if any, payable upon the issue or sale of such Convertible
Securities and upon the conversion or exchange thereof, by (ii) the Common
Shares issuable upon the exercise of such Options or upon the conversion or
exchange of all such Convertible Securities issuable upon the exercise of such
Options) shall be less than the per-share Fair Market Value of the Common Shares
as of the end of the day immediately preceding the granting of such Options,
then the total maximum number of Common Shares issuable upon the exercise of
such Options or upon conversion or exchange of the total maximum amount of such
Convertible Securities shall be deemed to have been issued for such price per
share as of the date of granting of such Options.  Except as otherwise provided
in Subsection 9(c)(iii)(d)(3), no adjustment of the Series B Conversion Price
shall be made upon the actual issuance of the Common Shares or Convertible
Securities upon exercise of such Options or upon the actual issuance of such
Common Shares upon conversion or exchange of such Convertible Securities.

              (2)    ISSUANCE OF CONVERTIBLE SECURITIES.  In case the
Corporation shall in any manner issue (whether directly or by assumption in a
merger or otherwise) or sell any Convertible Securities, whether or not the
rights to exchange or convert any such Convertible Securities are immediately
exercisable, and the price per share for which the Common Shares are issuable
upon such conversion or exchange (determined by dividing (i) the total amount
received or receivable by the Corporation as consideration for the issuance or
sale of such Convertible Securities, plus the minimum aggregate amount of
additional consideration, if any, payable to the Corporation upon the conversion
or exchange thereof, by (ii) the total maximum number of Common Shares issuable
upon the conversion or exchange of all such Convertible Securities) shall be
less than the per-share Fair Market Value of the Common Shares as of the end of
the day immediately preceding such issuance or sale, then the Common Shares
issuable upon conversion or exchange of all such Convertible Securities shall be
deemed to have been issued for such price per share as of the date of the
issuance or sale of such Convertible Securities and thereafter shall be deemed
to be outstanding, PROVIDED that (a) except as otherwise provided in Subsection
9(c)(iii)(d)(3), no adjustment of the Series B Conversion Price shall be made
upon the actual issuance of such Common Shares upon conversion or exchange of
such Convertible Securities and (b) if any such issuance or sale of such
Convertible Securities is made upon exercise of any Options to purchase any such
Convertible Securities for which adjustments of the Series B Conversion Price
have been or are to be made pursuant to other provisions of this Subsection
9(c)(iii)(d), no further adjustment of the Conversion Price shall be made by
reason of such issuance or sale.

              (3)    CHANGE IN OPTION PRICE OR CONVERSION RATE.  Upon the
happening of any of the following events, namely, if the purchase price provided
for in any Option referred to in Subsection 9(c)(iii)(d)(1), or the rate at
which Convertible Securities referred to in Subsection


                                      31

<PAGE>

9(c)(iii)(d)(2) are convertible into or exchangeable for Common Shares shall
change at any time (including, but not limited to, changes under or by reason
of provisions designed to protect against dilution), the Series B Conversion
Price in effect at the time of such event shall forthwith be readjusted to
the Series B Conversion Price which would have been in effect at such time
had such Options or Convertible Securities still outstanding provided for
such changed purchase price, additional consideration or conversion rate, as
the case may be, at the time initially granted, issued or sold; and on the
expiration of any such Option or termination of any such right to convert or
exchange such Convertible Securities, the Conversion Price then in effect
hereunder shall forthwith be increased to the Conversion Price which should
have been in effect at the time of such expiration or termination had such
Option or Convertible Securities, to the extent outstanding immediately prior
to such expiration or termination, never been issued.

              (4)    CONSIDERATION FOR SHARES.  In case any Common Shares,
Options or Convertible Securities shall be issued or sold for cash, the
consideration received therefor shall be deemed to be the amount received by the
Corporation therefor, without deduction therefrom of any expenses incurred or
any underwriting commissions or concessions paid or allowed by the Corporation
in connection therewith.  In case Common Shares, Options or Convertible
Securities shall be issued or sold for a consideration in whole or in part other
than cash, the amount of the consideration other than cash received by the
Corporation shall be deemed to be the fair market value of such consideration as
determined in good faith by the Board of Directors of the Corporation, without
deduction of any expenses incurred or any underwriting commissions or
concessions paid or allowed by the Corporation in connection therewith.  In case
any Options shall be issued in connection with the issuance or sale of other
securities of the Corporation, together comprising one integral transaction in
which no specific consideration is allocated to such Options by the parties
thereto, such Options shall be deemed to have been issued for such consideration
as determined in good faith by the Board of Directors of the Corporation.

              (5)    RECORD DATE.  In case the Corporation shall take a record
of the holders of its Common Shares for the purpose of entitling them (i) to
receive a dividend or other distribution payable in Common Shares, Options or
Convertible Securities, or (ii) to subscribe for or purchase Common Shares,
Options or Convertible Securities, then such record date shall be deemed to be
the date of the issuance or sale of the Common Shares deemed to have been issued
or sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be, and, in each such case, the number of Common
Shares into which shares of Series B Preferred Stock may be converted shall be
increased in proportion to the increase (through such dividend or distribution)
in the number of outstanding Common Shares, by reducing the Series B Conversion
Price in the same proportion.

       (e)    CERTAIN ISSUES OF COMMON SHARES EXCEPTED.  Anything herein to the
contrary notwithstanding, the Corporation shall not be required to make any
adjustment of the Series B Conversion Price pursuant to Subsection 9(c)(iii)(d)
in the case of the issuance of: (i) up to an aggregate of four million nine
hundred and ninety thousand (4,990,000) Common Shares (appropriately adjusted
for stock splits, dividends, consolidations, recapitalizations and similar
events), pursuant to the Corporation's 1993 Stock Option Plan, as amended; (ii)
up to an


                                      32

<PAGE>

aggregate of five million six hundred eighty-six thousand, five hundred
(5,686,500) Common Shares (appropriately adjusted for stock splits, dividends,
consolidations, recapitalizations and similar events) pursuant to the exercise
of outstanding warrants; and (iii) such other securities as the holders of
sixty-six and two-thirds percent (66 2/3%) of the then outstanding shares of
Series B Preferred Stock shall agree in writing may be issued without causing an
adjustment in the Series B Conversion Price.

       (f)    SUBDIVISION OR COMBINATION OF COMMON SHARES.  In case the
Corporation shall at any time subdivide (by any stock split, stock dividend or
otherwise) its outstanding Common Shares into a greater number of shares,
without making a corresponding subdivision of the outstanding shares of Series B
Preferred Stock, then the Series B Conversion Price in effect immediately prior
to such subdivision shall be proportionately reduced.  Conversely, in case the
outstanding Common Shares shall be combined into a smaller number of shares
without a corresponding adjustment to the number of outstanding shares of Series
B Preferred Stock, then the Series B Conversion Price in effect immediately
prior to such combination shall be proportionately increased.

       (g)    OTHER DISTRIBUTIONS. If the Corporation shall declare a
distribution payable in securities of other persons (including, but not limited
to, spin-offs of a business whereby, for example, an asset of the Corporation is
contributed to a subsidiary which is spun-off to the Corporation's
shareholders), evidences of indebtedness issued by this Corporation or other
persons, assets (excluding cash dividends) or options or rights not referred to
in Subsection 9(c)(iii)(h), then, in each such case for the purpose of this
Subsection 9(c)(iii)(g), the holders of the Series B Preferred Stock shall be
entitled to a proportionate share of any such distribution as though they were
the holders of the number of Common Shares into which their shares of Series B
Preferred Stock are convertible as of the record date fixed for the
determination of the holders of Common Shares entitled to receive such
distribution.

       (h)    REORGANIZATION OR RECLASSIFICATION.  If any capital reorganization
or reclassification of the capital stock of the Corporation shall be effected in
such a way that holders of Common Shares shall be entitled to receive stock,
securities or assets with respect to or in exchange for Common Shares, then, as
a condition of such reorganization or reclassification, lawful and adequate
provisions shall be made whereby each holder of a share or shares of Series B
Preferred Stock shall thereupon have the right to receive, upon the basis and
upon the terms and conditions specified herein and in lieu of the Common Shares
immediately theretofore receivable upon the conversion of such shares of Series
B Preferred Stock, such shares of stock, securities or assets as may be issued
or payable with respect to or in exchange for a number of outstanding shares of
such Series B Preferred Stock equal to the number of Common Shares immediately
theretofore receivable upon such conversion had such reorganization or
reclassification not taken place, and in any such case appropriate provisions
shall be made  with respect to the rights and interests of such holder to the
end that the provisions hereof shall thereafter be applicable, as nearly as may
be, in relation to any shares of stock, securities or assets thereafter
deliverable upon the exercise of such conversion rights.


                                      33

<PAGE>

       (i)    NOTICE OF ADJUSTMENT.  Upon any adjustment of the Series B
Conversion Price, then, and in each such case, the Corporation shall give
written notice thereof as soon as practicable thereafter, by first class,
registered or certified mail, postage prepaid, return receipt requested, or by
telecopier (to be promptly followed by notice sent by registered or certified
mail, return receipt requested, as set forth above), addressed to each holder of
shares of Series B Preferred Stock, as the case may be, at the address of such
holder as shown on the books of the Corporation, which notice shall state the
conversion rate resulting from such adjustment and the manner in which such
calculation was made.

       (j)    SHARES TO BE RESERVED.  The Corporation will at all times reserve
and keep available out of its authorized, but unissued, Common Shares, solely
for the purpose of issuance upon the conversion of Series B Preferred Stock as
herein provided, such number of Common Shares as shall then be issuable upon the
conversion of all outstanding shares of Series B Preferred Stock.  The
Corporation covenants that all Common Shares which shall be so issued shall be
duly and validly issued, fully paid, nonassessable and free from all taxes,
liens and charges with respect to the issue thereof.  The Corporation will take
such action as may be necessary to assure that all Common Shares may be so
issued without violation of any applicable law or regulation, or of any
requirement of any securities exchange upon which the Common Shares may be
listed.

       (k)    ISSUE TAX.  The issuance of certificates for Common Shares upon
conversion of Series B Preferred Stock shall be made without charge to the
holders thereof for any issuance tax in respect thereof, provided that the
Corporation shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of any certificate in a
name other than that of the holder (or its affiliate) of the Series B Preferred
Stock.

(iv)   VOTING.

       (a)    SHAREHOLDER VOTING.  Holders of the outstanding Series B Preferred
Stock shall be entitled to cast, on all matters submitted to a vote of all of
the shareholders of the Corporation (including in the election of directors,
except as set forth in Subsections 9(b)(iv) and 9(b)(v)) and on which
shareholders are entitled to vote under the provisions of the Wyoming Business
Corporation Act, that number of votes equal to the number of Common Shares into
which such outstanding Series B Preferred Stock is then convertible under
Subsection 9(c)(iii) at the record date for the determination of shareholders
entitled to vote on such matter, and with respect to such vote, shall be
entitled, notwithstanding any provision hereof, to notice of any stockholders'
meeting in accordance with the Bylaws of this Corporation.  Fractional votes
shall not, however, be permitted and any fractional voting rights resulting from
the aforementioned formula (after aggregating all shares into which shares of
Series B Preferred Stock held by each holder could be converted) shall be
rounded to the nearest whole number (with one-half rounded upward to one).  In
addition to their right to elect the Series B Director, as provided below, and
except as set forth in Subsections 9(b)(iv) and 9(b)(v), holders of Series B
Preferred Stock shall vote together with the holders of Series A Preferred Stock
and Common Shares on all such matters except as otherwise provided herein.


                                      34

<PAGE>

       (b)    SERIES B DIRECTOR.

              (1)    Upon the issuance of Series B Preferred Stock, the
Corporation shall name to its Board of Directors a director identified to it by
Larry Gordon, the Series B Preferred Stock representative; provided that such
director is reasonably acceptable to the Corporation.  Thereafter, and for so
long as more than fifty percent (50%) of all shares of Series B Preferred Stock
issued by the Corporation shall be outstanding, the holders of the Series B
Preferred Stock, voting as a separate voting group, shall be entitled to elect
one (1) director to the Corporation's Board of Directors ("Series B Director")
at the annual meeting of the Corporation's shareholders and otherwise if there
is a vacancy of the directorship held by the Series B Director.  If the
aforementioned minimum outstanding shares requirement has been met, then at any
meeting held for the purpose of electing directors, the presence in person or by
proxy of the holders of a majority of the outstanding shares of Series B
Preferred Stock shall constitute a quorum of such shares for the election of the
director to be elected.

              (2)    Except as otherwise provided by law, the Series B Director
shall be elected by a majority of the votes cast by the Series B Preferred Stock
at a meeting of shareholders at which a quorum is present.  Provided that the
minimum outstanding shares requirement in Subsection 9(c)(iv)(b)(1) is met, any
vacancy in any directorship elected by the holders of Series B Preferred Stock
shall be filled only by the vote or written consent of the holders of a majority
of the then outstanding shares of Series B Preferred Stock.  Any director who
shall have been elected by the holders of Series B Preferred Stock may be
removed from office, whether with or without cause, only by the vote or written
consent of the holders of a majority of the then outstanding shares of Series B
Preferred Stock.

       (c)    NONCOMPLIANCE.  If the Corporation fails to comply with
Subsections 9(c)(iv)(b), then, in addition to any other legal remedies available
to the holders of the Series B Preferred Stock, the number of directors that the
holders of the then outstanding shares of Series B Preferred Stock shall be
entitled to elect under Subsection 9(c)(iv)(b) shall be increased to a total of
three (3) directors, effective immediately upon such noncompliance and for as
long as such noncompliance exists.

(v)    RESTRICTIONS.  For so long as more than fifty percent (50%) of all shares
of Series B Preferred Stock issued by the Corporation shall be outstanding,
except where the vote or written consent of the holders of a greater number of
shares of the Corporation is required by law or by the Articles of
Incorporation, and in addition to any other vote required by law or the Articles
of Incorporation, the Corporation will not take any of the following actions
without the approval of the holders of at least sixty-six and two-thirds percent
(66 2/3%) of the then outstanding shares of Series B Preferred Stock, given in
writing or by vote at a meeting, consenting or voting (as the case may be) as a
separate voting group:

       (a)    Engage in any transaction resulting in a "Change of Control
("Change in Control" shall mean and occur when (i) any "person" as such term is
defined in Section 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), other than a trustee or other fiduciary holding
securities under an employee benefit plan of the Corporation, is


                                      35

<PAGE>

or becomes a beneficial owner (within the meaning of rule 13d-3 promulgated
under the Exchange Act), directly or indirectly, of securities of the
Corporation, representing fifty-one percent (51%) or more of the combined
voting power of the Corporation's then outstanding securities; or (ii) the
shareholders of the Corporation approve a reorganization, merger or
consolidation of the Corporation with any other corporation or entity, other
than a reorganization, merger or consolidation which would result in the
voting securities of the Corporation outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) at least fifty-one
percent (51%) of the combined voting power of the voting securities of the
Corporation or such surviving entity outstanding immediately after such
reorganization, merger or consolidation; or (iii) the shareholders of the
Corporation approve a plan of complete liquidation, dissolution or winding up
of the Corporation or an agreement for the sale or disposition by the
Corporation of all or substantially all of its assets);

       (b)    Pay or declare any dividends or make any distribution with respect
to any holder of Common or Preferred Shares junior to the Series B Preferred
Stock;

       (c)    Redeem or otherwise repurchase any shares of Common or Preferred
Shares junior to the Series B Preferred Stock; or

       (d)    Enter into any transactions with any of its affiliates, unless
each such transaction is on terms at least as favorable as those available to
the Corporation from disinterested third parties and such transaction is
approved by the Board of Directors, including the Series B Director (provided
that the Series B Director is not an interested party in such transaction); or

       (e)    Unless approved by the Board of Directors and the Series B
Director, (i) increase the number of Common Shares available under the
Corporation's 1993 Stock Option Plan, as amended, by more than an aggregate of
three million (3,000,000) Common Shares (appropriately adjusted for stock
splits, dividends, consolidations, recapitalizations and similar events); (ii)
issue or grant more than an aggregate of five million six hundred eighty-five
thousand, five hundred (5,685,500) Common Shares (appropriately adjusted for
stock splits, dividends, consolidations, recapitalizations and similar events)
pursuant to the exercise of outstanding warrants; and (iii) issue or grant other
rights to purchase Common Shares, pursuant to an employment compensation plan.

(vi)   SINKING FUND.  There shall be no sinking fund provision for the payment
of dividends, liquidation preferences, or redemption of the shares of Series B
Preferred Stock.

(vii)  REDEMPTION OF SERIES B PREFERRED STOCK.

       (a)    MANDATORY REDEMPTION.  If a Change of Control (as defined in
Subsection 9(c)(v)(a)) has occurred, the Corporation shall offer to redeem all
of the outstanding shares of Series B Preferred Stock for cash, at a price per
share equal to one hundred and fifty percent (150%) of the liquidation
preference for Series B Preferred Stock under Subsection 9(c)(ii)(a), plus any
declared, but unpaid, dividends under Subsection 9(c)(i), by providing each
holder of Series B Preferred Stock with written notice of such redemption
("Redemption Offer Notice")


                                      36

<PAGE>

within thirty (30) days of such Change of Control. If any holder of Series B
Preferred Stock does not elect in writing within twenty (20) days of the date
of the Redemption Offer Notice ("Election Period") to have all of such
holder's shares of Series B Preferred Stock redeemed, then, with respect to
the holder's unredeemed shares of Series B Preferred Stock, such holder's
mandatory redemption rights hereunder shall terminate as to such Change of
Control event.  If any of the holders of the outstanding shares of Series B
Preferred Stock elects redemption before the expiration of the Election
Period, then the Corporation shall notify such holder of the redemption
within ten (10) days following the end of the Election Period ("Mandatory
Redemption Notice").  Within ten (10) days of the receipt of the Mandatory
Redemption Notice, such holder shall surrender to the Corporation the
certificate(s) representing such shares of Series B Preferred Stock to be
redeemed duly endorsed for transfer to this Corporation, and upon receipt of
such certificates, the Corporation shall pay the redemption price for such
shares to the order of the person whose name appears on such certificate(s)
as the owner thereof, and each surrendered certificate shall be cancelled.
As to any portion of the shares of Series B Preferred Stock so surrendered
which are not subject to such holder's redemption election, the Corporation
shall promptly issue to the person whose name appears on such certificate(s)
a certificate in due and proper form representing the shares of Series B
Preferred Stock which have not been redeemed.  When the redemption price is
paid, all rights in respect of the redeemed shares of Series B Preferred
Stock shall cease and terminate, and such shares shall no longer be deemed to
be outstanding, whether or not the certificates representing such shares have
been received by the Corporation.

       (b)    OPTIONAL REDEMPTION.  If from and after one year of the date the
first share of Series B Preferred Stock is sold and issued by the Corporation,
the Common Shares shall have traded above seventy-five cents ($0.75) per share
(as adjusted for stock splits, dividends, consolidations, recapitalizations and
similar events) for sixty (60) consecutive days on a national securities
exchange or NASDAQ, or the closing bid price quoted by an established quotation
service for over-the-counter securities shall be above seventy-five cents
($0.75) for sixty (60) consecutive days, then the Corporation shall have the
right, but not the obligation, to redeem all of the outstanding shares of Series
B Preferred Stock for cash, at a price per share equal to one hundred and fifty
percent (150%) of the liquidation preference for Series B Preferred Stock under

Subsection 9(c)(i), by providing each holder of Series B Preferred Stock with
written notice of such redemption not less than thirty (30) days prior to the

such redemption, and prior to the scheduled date of redemption, holders of

representing such shares of Series B Preferred Stock to be redeemed duly
endorsed for transfer to this Corporation, and upon receipt of such
certificates, the Corporation shall pay the redemption price for such shares to

thereof, and each surrendered certificate shall be cancelled.  When the
redemption price is paid, all rights in respect of redeemed shares of Series B
Preferred Stock shall cease and terminate, and such shares shall no longer be
deemed to be outstanding, whether or not the certificates representing such
shares have been received by the Corporation.  Nothing herein contained in this
Subsection 9(c)(vii)(b) shall prohibit any holder of Series B Preferred Stock
from electing the benefits of the provisions

the scheduled date of redemption.

       (c)    NONCOMPLIANCE/CONVERSION PRICE ADJUSTMENT.  If (i) any of the
holders of Series B Preferred Stock elects redemption under Subsection
9(c)(vii)(a) and complies with the provisions therein; and (ii) the Corporation
fails to redeem any of such holder's shares of Series B Preferred Stock as
required therein, then the Series B Conversion Price for those unredeemed shares
of Series B Preferred Stock shall be reduced by one percent (1%) on the seventh
(7th) day following such noncompliance and by an additional one percent (1%)
every seven (7) days thereafter until the redemption has been made.

(viii) NONCOMPLIANCE WITH REGISTRATION RIGHTS/CONVERSION PRICE ADJUSTMENT.  If
all of the conditions set forth in Section 5.1 of that certain Investor Rights
Agreement between the Corporation and the holders of Series B Preferred Stock
have been met and the Corporation fails to comply with the registration rights
provisions set forth in such Section 5.1, then the Series B Conversion Price for
those shares of Series B Preferred Stock which the Corporation has failed to
register shall be reduced by one percent (1%) on the seventh (7th) day following
such noncompliance and by an additional one percent (1%) every seven (7) days
thereafter until the registration of such shares has been made.

with Rule 144), unless there is in effect a registration statement under the
Securities Act covering the proposed transfer, the holder thereof shall give
written notice to the Company of such holder's intention to effect such
transfer, sale, assignment or pledge.  Each such notice shall describe the
manner and circumstances of the proposed transfer, sale, assignment or pledge in
sufficient detail, and shall be accompanied, at such holder's expense by either
(i) written opinion of legal counsel who shall be, and whose legal opinion shall

without registration under the Securities Act, or (ii) a "no action" letter from
the Commission to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by the holder to the
Company.  It is agreed that the Company will not request an opinion of counsel

provided shall bear, except if such transfer is made pursuant to Rule 144, the
appropriate restrictive legend set forth in SECTION 3 above, except that such
certificate shall not bear such restrictive legend if in the opinion of counsel
for such holder (if required above) and the Company such legend is not required
in order to establish compliance with any provision of the Securities Act.

                                          to use its best efforts to register,

                                          under this SECTION 5.1 shall be
                                          deferred for a period not to exceed
                                          ninety (90) days from the date of
                                          receipt of written request from the
                                          Initiating Holders, provided that the
                                          Company may not exercise this deferral
                                          right more than once per twelve (12)
                                          month period.  Subject to the
                                          foregoing clauses, the Company shall
                                          file a registration statement covering
                                          the Registrable Securities so
                                          requested to be registered as soon as
                                          practicable after receipt of the
                                          request or requests of the Initiating
                                          Holders;

                     (ii)   UNDERWRITING.  If the Initiating Holders intend to
                            distribute the Registrable Securities covered by
                            their request by means of an underwriting, they
                            shall so advise the Company as a part of their
                            request made pursuant to SECTION 5.1(i), and the
                            Company shall include such information in the
                            written notice given pursuant to SECTION 5.1(i).
                            The managing underwriter will be selected by a
                            majority in interest of the Initiating Holders,
                            provided that such managing underwriter is
                            reasonably acceptable to the Company.  In such
                            event, the right of any Holder to include his or her
                            Registrable Securities in such registration shall be
                            conditioned upon such Holder's participation in such
                            underwriting and the inclusion of such Holder's
                            Registrable Securities in the underwriting (unless
                            otherwise mutually agreed by a majority in interest
                            of the Initiating Holders and such Holder) to the
                            extent provided herein.

              The Company shall (together with all Holders proposing to
distribute their securities through such underwriting) enter into an
underwriting agreement in customary form with the managing underwriter.
Notwithstanding any other provision of this SECTION 5.1, if the managing
underwriter advises the Initiating Holders in writing that marketing factors
require a limitation of the number of shares to be underwritten, then the
Company shall so advise all Holders of Registrable Securities, and the number of
shares of Registrable Securities that may be included in the registration and
underwriting shall be allocated among all Holders in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities held by such
Holders at the time of filing the registration statement.  Neither the Company
nor any other holders of Company securities may participate in the proposed
offering if any Holders have been cut back pursuant to this SECTION 5.1(ii).  No
Registrable Securities excluded from the underwriting by reason of the
underwriter's marketing limitation shall be included in such registration.  To
facilitate the allocation of shares in accordance with the above provisions, the
Company or the underwriters may round the number of shares allocated to any
Holder to the nearest 100 shares.

              If any Holder of Registrable Securities disapproves of the terms
of the underwriting, such person may elect to withdraw therefrom by written
notice to the Company, the managing underwriter and the Initiating Holders.  The
Registrable Securities and/or other


                                      46

<PAGE>

securities so withdrawn shall also be withdrawn from registration, and such
Registrable Securities shall continue to be subject to the terms of this
Agreement including SECTION 6 hereof.

              5.2    COMPANY REGISTRATION.

                     (a)    NOTICE OF REGISTRATION.  If at any time, or from
time to time, the Company shall determine to register any of its equity
securities, either for its own account or the account of a security holder or
holders, other than (i) a registration relating solely to employee benefit
plans, (ii) a registration relating solely to a Rule 145 transaction, the
Company will:

                            (1)    promptly give to each Holder written notice
                                   thereof; and

                            (2)    include in such registration (and any related
                                   qualification under blue sky laws or other
                                   compliance), and in any underwriting involved
                                   therein, all the Registrable Securities
                                   specified in a written request or requests,
                                   made within twenty (20) days after receipt of
                                   such written notice from the Company, by any
                                   Holder.

                     (b)    UNDERWRITING.  If the registration of which the
Company gives notice is for a registered public offering involving an
underwriting, the Company shall so advise the Holders as a part of the written
notice given pursuant to SECTION 5.2(a)(i).  In such event the right of any
Holder to registration pursuant to this SECTION 5.2 shall be conditioned upon
such Holder's participation in such underwriting, and the inclusion of
Registrable Securities in the underwriting shall be limited to the extent
provided herein.

              All Holders proposing to distribute their securities through such
underwriting shall (together with the Company and the other holders distributing
their securities through such underwriting) enter into an underwriting agreement
in customary form with the managing underwriter selected for such underwriting
by the Company.  Notwithstanding any other provision of this SECTION 5.2, if the
managing underwriter determines that marketing factors require a limitation of
the number of shares to be underwritten, the managing underwriter may exclude
some or all of the Registrable Securities, or securities of other holders of
registration rights other than persons exercising demand registration rights,
from such registration.  The Company shall advise all Holders, and other holders
distributing their securities through such underwriting of any limits imposed on
their participation in the underwriting as provided in this SECTION 5.2(b).  The
number of shares of Registrable Securities, or securities of other holders of
registration rights other than persons exercising demand registration rights,
that may be included in the registration and underwriting in accordance with
this SECTION 5.2(b) shall be allocated among all the Holders and such other
holders of securities not exercising demand registration rights pro rata.

              If any Holder or other holder disapproves of the terms of any such
underwriting, he or she may elect to withdraw therefrom by written notice to the
Company and the managing underwriter.  Any securities excluded or withdrawn


                                      47

<PAGE>

from such underwriting shall be withdrawn from such registration, and shall
continue to be subject to the terms of this Agreement, including SECTION 6
hereof. Furthermore,

                            (i)    No shareholder of the Company shall be
                                   granted any rights superior to those granted
                                   to the Preferred Stockholders pursuant to
                                   this SECTION 5.2 without the prior consent of
                                   more than Fifty-One Percent (51%) of (i) the
                                   then outstanding shares of Preferred Stock
                                   plus (ii) if some or all of the Preferred has
                                   been converted into Common Stock, the
                                   Conversion Stock issued pursuant to such
                                   conversion and Shares underlying the
                                   Warrants.

                            (ii)   RIGHT TO TERMINATE REGISTRATION.  The Company
                                   shall have the right to terminate or withdraw
                                   any registration initiated by it under this
                                   SECTION 5.2 prior to the effectiveness of
                                   such registration whether or not any Holder
                                   has elected to include securities in such
                                   registration.

              5.3    REGISTRATION ON FORM S-3.

                     (a)    If any Holder or Holders of at least Five Percent
(5%) of the then outstanding Registrable Securities request that the Company
file a registration statement on Form S-3 (or any successor form to Form S-3)
for a public offering of all or some of the shares of the Registrable Securities
held by such Holder or Holders and the reasonably anticipated aggregate price to
the public of which, net of underwriting discounts and commissions, would exceed
FIVE HUNDRED THOUSAND DOLLARS ($500,000), and the Company is a registrant
entitled to use Form S-3 to register the Registrable Securities for such an
offering, the Company shall use its best efforts to cause such Registrable
Securities to be registered for the offering on such form and to cause such
Registrable Securities to be qualified in such jurisdictions as such Holder or
Holders may reasonably request.  The Company shall inform other Holders of the
proposed registration and offer them the opportunity to participate.  In the
event the registration is proposed to be part of a firm commitment underwritten
public offering, the substantive provisions of SECTION 5.1(ii) shall be
applicable to each such registration initiated under this SECTION 5.3.  The
Company may include other shares of Common Stock in any of the registrations
provided for in this SECTION 5.3, provided that such inclusion will not
interfere with the marketing (including the price to the public) of the
Registrable Securities to be registered by the Holders.

                     (b)    Notwithstanding the foregoing, the Company shall not
be obligated to take any action pursuant to this SECTION 5.3 if any of the
conditions in Section 5.1(a), (b) or (d) exist or to Blue-Sky in a jurisdiction
where in the good faith judgment of the Board of Directors, it would be
unreasonably burdensome to qualify.

              5.4    EXPENSES OF REGISTRATION.  Registration Expenses incurred
in connection with (i) up to one requested registrations pursuant to SECTION
5.1, (ii) all company registrations


                                      48

<PAGE>

pursuant to SECTION 5.2, and (iii) all Form S-3 registrations pursuant to
SECTION 5.3 shall be borne by the Company. Selling Expenses shall be borne by
the selling shareholders incurring such expenses.

              5.5    REGISTRATION PROCEDURES.  In the case of each registration,
qualification or compliance effected by the Company pursuant to this Agreement,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof.  At its expense, the Company will:

                     (a)    Prepare and file with the Commission a registration
statement with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for at least ninety (90)
days or until the distribution described in the registration statement has been
completed, whichever first occurs; PROVIDED, HOWEVER, that (i) such 90-day
period shall be extended for a period of time equal to the period the Holder
refrains from selling any securities included in such registration at the
request of an underwriter of Common Stock (or other securities) of the Company;
and (ii) in the case of any registration of Registrable Securities on Form S-3
which are intended to be offered on a continuous or delayed basis, such 90-day
period shall be extended up to a maximum total period of one year, if necessary,
to keep the registration statement effective until all such Registrable
Securities are sold, provided that Rule 415, or any successor rule under the
Securities Act, permits an offering on a continuous or delayed basis, and
provided further that applicable rules under the Securities Act governing the
obligation to file a post-effective amendment permit, in lieu of filing a
post-effective amendment which (I) includes any prospectus required by Section
10(a)(3) of the Act or (II) reflects facts or events representing a material or
fundamental change in the information set forth in the registration statement,
the incorporation by reference of information required to be included in (I) and
(II) above to be contained in periodic reports filed pursuant to Section 13 or
15 (d) of the Securities Exchange Act of 1934 (the "1934 ACT") in the
registration statement.

                     (b)    Prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the Act with respect to the disposition of all securities
covered by such registration statement.

                     (c)    Furnish to the Holders participating in such
registration and to the underwriters of the securities being registered such
reasonable number of copies of the registration statement, preliminary
prospectus, final prospectus and such other documents (including amendments or
supplements thereto) as such Holders or underwriters may reasonably request in
order to facilitate the public offering of such securities.

                     (d)    Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders; provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general


                                      49
<PAGE>

consent to service of process in any such states or jurisdiction, unless the
Company is already subject to service in such jurisdiction.  Furthermore,

                            (i)    In the event of any underwritten public
                                   offering, enter into and perform its
                                   obligations under an underwriting agreement,
                                   in usual and customary form, with the
                                   managing underwriter of such offering.  Each
                                   Holder participating in such underwriting
                                   shall also enter into and perform its
                                   obligations under such an agreement.

                            (ii)   Notify each Holder of Registrable Securities
                                   covered by such registration statement at any
                                   time when a prospectus relating thereto is
                                   required to be delivered under the Act of the
                                   happening of any event as a result of which
                                   the prospectus included in such registration
                                   statement, as then in effect, includes an
                                   untrue statement of a material fact or omits
                                   to state a material fact required to be
                                   stated therein or necessary to make the
                                   statements therein not misleading in the
                                   light of the circumstances then existing and
                                   as promptly as practicable amend or
                                   supplement the prospectus to correct such
                                   misstatement or omission.

                            (iii)  Cause all such Registrable Securities
                                   registered pursuant hereunder to be listed on
                                   each securities exchange on which similar
                                   securities issued by the Company are then
                                   listed.

                            (iv)   Provide a transfer agent and registrar for
                                   all Registrable Securities registered
                                   pursuant hereunder and a CUSIP number for all
                                   such Registrable Securities, in each case not
                                   later than the effective date of such
                                   registration.

                            (v)    Furnish, at the request of any Holder
                                   requesting registration of Registrable
                                   Securities pursuant to this SECTION 5.5, on
                                   the date that such Registrable Securities are
                                   delivered to the underwriters for sale in
                                   connection with a registration pursuant to
                                   this SECTION 5.5, if such securities are
                                   being sold through underwriters, (i) an
                                   opinion, dated such date, of the counsel
                                   representing the Company for the purposes of
                                   such registration, in form and substance as
                                   is customarily given to underwriters in an
                                   underwritten public offering, addressed to
                                   the underwriters, and (ii) a letter dated
                                   such date, from the independent certified

                                   offering, addressed to the underwriters.

                            (vi)   In the event of any underwritten public
                                   offering, cooperate with the Holders
                                   requesting registration pursuant to this

                                   the offering and their counsel in any due
                                   diligence investigation reasonably requested
                                   by the Holders or the underwriters in
                                   connection therewith, and participate, to the
                                   extent reasonably requested by the managing
                                   underwriter for the offering or the Holders,
                                   in efforts to sell the Registrable Securities
                                   under the offering (including without
                                   limitation, participating in "roadshow"
                                   meetings with prospective investors) that
                                   would be customary for underwritten primary
                                   offerings of a comparable amount of equity
                                   securities by the Company.

              5.6    INDEMNIFICATION.

                     (a)    The Company will indemnify each Holder, each of such
Holder's officers, directors, members, partners, legal counsel and agent, and
each person controlling such Holder within the meaning of Section 15 of the
Securities Act, with respect to which registration, qualification or compliance
has been effected pursuant to this Agreement, and each underwriter, if any, and
each person who controls any underwriter within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages or liabilities (or
actions in respect thereof), including any of the foregoing incurred in
settlement of any litigation, commenced or threatened, arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any registration statement, prospectus, offering circular or other
document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance, or based on 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 or any violation by the
Company of the Securities Act of 1933, the Securities Exchange Act of 1934,
state securities law or any rule or regulation promulgated under such laws
applicable to the Company in connection with any such registration,
qualification or compliance, and the Company will reimburse each such Holder,
each of such Holder's officers and directors, and members, partners, legal
counsel, agents and each person controlling such Holder, each such underwriter
and each person who controls any such underwriter, for any legal and any other
expenses reasonably incurred, as such expenses are incurred, in connection with
investigating, preparing or defending of any such claim, loss, damage, liability
or action, provided that the Company will not be liable in any such case to the
extent that any such claim, loss, damage, liability or expense arises out of or
is based on any untrue statement or omission or alleged utrue statement or
omission, made in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder,
controlling person or underwriter and stated to be specifically for use therein.


                                      51

<PAGE>

                     (b)    Each Holder severally, and not jointly will, if
Registrable Securities held by such Holder are included in the securities as to
which such registration, qualification or compliance is being effected,
indemnify the Company, each of its directors and officers, each underwriter, if
any, of the Company's securities covered by such a registration statement, each
person who controls the Company or such underwriter within the meaning of
Section 15 of the Securities Act, and each other such Holder, each of such
Holder's officers and directors and each person controlling such Holder within
the meaning of Section 15 of the Securities Act, against all claims, losses,
damages and liabilities (or actions in respect thereof) arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any such registration statement, prospectus, offering circular or
other document, or 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, and will reimburse the Company, such Holders, such
directors, officers, persons, underwriters or control persons for any legal or
any other expenses reasonably incurred, as such expenses are incurred, in
connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder and
stated to be specifically for use therein.  Not withstanding the foregoing, the
liability of each Holder under this SUBSECTION 5.6(B) shall be limited in an
amount equal to the net proceeds received from the sale of the shares sold by
such Holder.

                     (c)    Each party entitled to indemnification under this
SECTION 5.6 (the "INDEMNIFIED PARTY") shall give notice to the party required to
provide indemnification (the "INDEMNIFYING PARTY") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Agreement unless the failure to
give such notice is materially prejudicial to an Indemnifying Party's ability to
defend such action and provided further, that the Indemnifying Party shall not
assume the defense for matters as to which there is a conflict of interest or
separate and different defenses.  No Indemnifying Party, in the defense of any
such claim or litigation, shall, except with the consent of each Indemnified
Party, consent to entry of any judgment or enter into any settlement which does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party of a release from all liability in respect
to such claim or litigation or which includes an admission of fault on behalf of
the Indemnified Party.

                     (d)    If the indemnification provided for in this SECTION
5.6 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage, or expense
referred to therein, then the Indemnifying Party, in lieu of


                                      52

<PAGE>

indemnifying such Indemnified Party hereunder, shall to the extent permitted
by applicable law contribute to the amount paid or payable by such
Indemnified Party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party on the one hand and of the Indemnified Party on the
other in connection with the statements or omissions that resulted in such
loss, liability, claim, damage, or expense as well as any other relevant
equitable considerations.  The relative fault of the indemnifying party and
of the Indemnified Party shall be determined by a court of law by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission to state a material fact relates to the
information supplied by the Indemnifying Party or by the Indemnified Party
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.
Notwithstanding the foregoing, the amount to be contributed by any Holder
under this SECTION 5.6(D) shall be limited to an amount equal to the net
proceeds received from the sale of the shares sold by such Holder.

                     (e)    Notwithstanding the foregoing, to the extent that
the provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

                     (f)    The obligations of the Company and the Holders under
this SECTION 5.6 shall survive completion of any offering of Registrable
Securities in a registration statement and the termination of this Agreement.
No Indemnifying Party shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to each Indemnified Party of a release from all liability in respect to such
claim or litigation; provided, that no Indemnified Party shall consent to entry
of any judgment or enter into any settlement without the consent of Indemnifying
Party.  No person guilty of fraudulent misrepresentations (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who is not guilty of such fraudulent misrepresentation.

              5.7    INFORMATION BY HOLDER.  The Holder or Holders of
Registrable Securities included in any registration shall furnish to the Company
such information regarding such Holder or Holders, the Registrable Securities
held by them and the distribution proposed by such Holder or Holders as the
Company may request in writing and as shall be required in connection with any
registration, qualification or compliance referred to in this Agreement.

              5.8    RULE 144 REPORTING.  With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the Restricted Securities to the public without
registration, the Company agrees to use all reasonable efforts to:

                     (a)    Make and keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act, at all
times after the effective date


                                      53

<PAGE>

that the Company becomes subject to the reporting requirements of the
Securities Act or the 1934 Act;

                     (b)    File with the Commission in a timely manner all
reports and other documents required of the Company under the Securities Act and
the 1934 Act (at any time after it has become subject to such reporting
requirements); and

                     (c)    So long as the Holder owns any Restricted Securities
to furnish to the Holder forthwith upon request a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144
(at any time after ninety (90) days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the 1934 Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents of the Company and other information in the possession of or
reasonably obtainable by the Company as the Holder may reasonably request in
availing itself of any rule or regulation of the Commission allowing the Holder
to sell any such securities without registration.

              5.9    TRANSFER OF REGISTRATION RIGHTS.  The rights to cause the
Company to register securities granted to the Holders under SECTIONS 5.1, 5.2
and 5.3 may be assigned to a transferee or assignee in connection with (a) any
transfer or assignment of Fifty Thousand (50,000) (as adjusted for stock splits,
stock dividends, recapitalizations and the like) or more shares of Registrable
Securities by the Holder to one or more persons in a single transaction or
series of related transactions, provided that (i) the Company is given notice
thereof and the transferee covenants to be bound by the provisions of this
Agreement and (ii) such transfer may otherwise be affected in accordance with
applicable securities laws or (b) any transfer or assignment of Registrable
Securities by the Holder to partners, members or affiliates of such Holder.

              5.10   SUBSEQUENT REGISTRATION RIGHTS.  From and after the date of
this Agreement, the Company shall not grant any registration rights to
subsequent purchasers of the Company's equity securities that are, in the good
faith judgment of the Company's Board of Directors, superior to the registration
rights granted to the Preferred Stockholders hereunder without the prior written
consent of the holders of at least Fifty One Percent (51%) of the Registrable
Securities.

              6.     AMENDMENT.  Any provision of this Agreement may be amended
or the observance thereof may be waived (either generally or in a particular
instance and either retroactively or prospectively), only with the written
consent of the Company and the holders of not less than a majority of the
Registrable Securities then outstanding. Any amendment or waiver effected in
accordance with this SECTION 6 shall be binding upon each Preferred Stockholder
and each Holder of Registrable Securities at the time outstanding (including
securities into which such securities are convertible), each future holder of
all such securities, and the Company.


                                      54

              7.     GOVERNING LAW.  This Agreement and the legal relations
between the parties arising hereunder shall be governed by and interpreted in
accordance with the laws of the State of California, without respect to rules
concerning the conflict of laws which would otherwise require application of the
substantive law of another jurisdiction.  The parties hereto agree to submit to
the jurisdiction of the federal and state courts of the State of California
matters with respect to the breach or interpretation of this Agreement or the
enforcement of any and all rights, duties, liabilities, obligations, powers, and
other relations between the parties arising under this Agreement.

expressly provided herein, the provisions hereof shall inure to the benefit of,
and be binding upon the successors, assigns, heirs, executors and administrators
of the parties hereto.

              9.     NOTICES.  All notices and other communications required or
permitted hereunder shall be in writing and shall be deemed effectively given

deposit with the United States mail, by registered or certified mail, postage
prepaid, addressed (a) if to a Preferred Stockholder, at such Preferred
Stockholder's address as set forth on the Schedule of Preferred Stockholders
attached hereto, or at such other address as such Preferred Stockholder shall
have furnished to the Company in writing in accordance with this SECTION 9, (b)
if to any other holder of Conversion Stock or Warrant Holder, at such address as
such holder shall have furnished the Company in writing in accordance with this
SECTION 9 or to the address set forth in the Series B Purchase Agreement, or,
until any such holder so furnishes an address to the Company, then to and at the
address of the last holder thereof who has so furnished an address to the
Company, or (c) if to the Company, at its principal office.

              10.    COUNTERPARTS.  This Agreement may be executed in any number

SECTION 2.    DURATION AND EXERCISE OF WARRANT

              2.1    EXERCISE PERIOD

              Subject to the provisions hereof, this Warrant may be exercised at
any time and from time to time during the period commencing on the Initial
Exercise Date and ending on the  Expiration Date.  After the Expiration Date,
this Warrant shall become void and all rights to purchase Warrant Shares
hereunder shall thereupon cease.

              2.2    METHOD OF EXERCISE AND PAYMENT

              (a)    METHOD OF EXERCISE.  Subject to Section 2.1 hereof and
compliance with all applicable Federal and state securities laws, the purchase
right represented by this Warrant may be exercised, in whole or in part, by the
Warrant Holder by (i) surrender of this Warrant and delivery of an exercise form
specifying the number of shares to be purchased, duly executed, at the principal
office of the Company and (ii) payment to the Company of an amount equal to the
product of the then applicable Exercise Price multiplied by the number of
Warrant Shares then being purchased.  At the election of the Warrant holder, the
purchase price may be paid by surrender of this Warrant for the full number of
shares for which this Warrant is then exercisable less that number of shares
having a fair market value equal to the aggregate exercise price.  For purposes
of this Section, fair market value shall be determined as follows: if the Common
Shares are then traded on the over-the-counter market on the date in question,
the last reported per-share sales price; provided that if there have been no
sales reported in the most recent two trading days at the time of determination,
then the closing bid price (or average of bid prices) last quoted on such date
by an established quotation service for over-the-counter securities.

              (b)    METHOD OF PAYMENT.  Payment shall be made either by check
drawn on a United States bank and for United States funds made payable to the
Company, or by wire transfer of United States funds for the account of the
Company, or by the cashless exercise provided above.

              (c)    DELIVERY OF CERTIFICATE.  In the event of any exercise of
the purchase right represented by this Warrant, certificates for the Warrant
Shares so purchased shall be delivered to the Warrant Holder within thirty (30)
days of delivery of the Exercise Form and, unless this Warrant has been fully
exercised or has expired, a new warrant representing the portion of the Warrant
Shares with respect to which this Warrant shall not then have been exercised
shall also be issued to the Warrant Holder within such thirty (30) day period.

              2.3    SECURITIES ACT COMPLIANCE/RESTRICTIONS UPON TRANSFER

                     Reference is made to Sections 2, 3 and 4 of the Investor
Rights Agreement which by this reference are incorporated herein.

                                       67

<PAGE>

SECTION 3.    VALIDITY AND RESERVATION OF WARRANT SHARES

              The Company represents and warrants that all Warrant Shares issued
upon exercise of this Warrant will be validly issued, fully paid, nonassessable
and not subject to preemptive or similar rights.  The Company agrees that, as
long as this Warrant may be exercised, the Company will have authorized and
reserved for issuance upon exercise of this Warrant a sufficient number of
shares of Common Stock to provide for exercise in full of this Warrant.

SECTION 4.    FRACTIONAL SHARES

              No fractional Warrant Shares shall be issued upon the exercise of
this Warrant, and the number of Warrant shares to be issued shall be rounded to
the nearest whole number.

SECTION 5.    LIMITED RIGHTS OF WARRANT HOLDER

              The Warrant Holder shall not, solely by virtue of being the
Warrant Holder of this Warrant, have any of the rights of a stockholder of the
Company, either at law or equity, until this Warrant shall have been exercised.

SECTION 6.    LOSS OF WARRANT

              Upon receipt by the Company of satisfactory evidence of the loss,
theft, destruction or mutilation of this Warrant and either (in the case of
loss, theft or destruction) reasonable indemnification and a bond satisfactory
to the Company if requested by the Company or (in the case of mutilation) the
surrender of this Warrant for cancellation, the Company will execute and deliver
to the Warrant Holder, without charge, a new warrant of like denomination.

SECTION 7.    CERTAIN ADJUSTMENTS OF EXERCISE PRICE

              7.1    ADJUSTMENT OF EXERCISE PRICE

              The number, class and Exercise Price of securities for which this
Warrant may be exercised are subject to adjustment from time to time upon the
happening of certain events as hereinafter provided:

              (a)    RECAPITALIZATION.  If the outstanding shares of the
Company's Common Stock are divided into a greater number of shares or the
Company issues a stock dividend on its outstanding Common Stock, the number of
shares of Common Stock purchasable upon the exercise of this Warrant shall be
proportionately increased and the Exercise Price shall be proportionately
reduced and, conversely, if the outstanding shares of Common Stock are combined
into a smaller number of shares of Common Stock, the number of shares of Common
Stock purchasable upon the exercise of this Warrant shall be proportionately
reduced and the Exercise Price shall be proportionately increased.  The
increases and reductions provided for in

                                       68

<PAGE>

this Section 7.1.(a) shall be made with the intent and, as nearly as
practicable, the effect that neither the percentage of the total equity of
the Company obtainable on exercise of this Warrant nor the price payable for
such percentage shall be affected by any event described in this Section 7.1
(a).

              (b)    MERGER OR REORGANIZATION, ETC.  In the event of any
change in the Common Stock through merger, consolidation, reclassification,
reorganization (such as, but not limited to, spin-offs of a business whereby,
for example, a Company asset is contributed to a subsidiary which is then
spun-off to the Company's shareholders), partial or complete liquidation or
other change in the capital structure of the Company (not including the
issuance of additional shares of capital stock other than by stock dividend
or stock split), then, as a condition of such change in the capital structure
of the Company, appropriate and adequate provision shall be made so that the
Warrant Holder of this Warrant will have the right thereafter to receive upon
the exercise of this Warrant the kind and amount of shares of stock or other
securities or property to which it would have been entitled if immediately
prior to such merger, consolidation, reclassification, reorganization,
recapitalization or other change in the capital structure, it had held the
number of shares of Common Stock then obtainable upon the exercise of this
Warrant.  In any such case appropriate adjustment shall be made in the
application of the provisions set forth herein with respect to the rights and
interest thereafter of the Warrant Holder, to the end that the provisions set
forth herein shall thereafter be applicable, as nearly as reasonably may be,
in relation to any shares of stock or other property thereafter deliverable
upon the exercise of this Warrant.

              (c)    Reference is made to Section 9 (c) (iii) (d) of the
Amendment to Articles.  It is agreed that if pursuant to said section of the
Amendment to Articles, the Series B Conversion ratio is required to be
adjusted, this Warrant shall likewise be adjusted on a proportional and
similar basis as the Series B Preferred Stock is adjusted.

              7.2    NOTICE OF ADJUSTMENT

              Whenever an event occurs requiring any adjustment to be made
pursuant to Section 7.1(a), 7.1(b) or (c), the Company shall promptly file
with its Secretary or an Assistant Secretary at its principal office and with
its stock transfer agent, if any, a certificate of its chief executive
officer specifying such adjustment, setting forth in reasonable detail the
acts requiring such adjustment, and stating such other facts as shall be
necessary to show the manner and figures used to compute such adjustment.
Such chief executive officer's certificate shall be made available at all
reasonable times for inspection by the Warrant Holder.  Promptly (but in no
event more than 30 days) after each such adjustment, the Company shall give a
copy of such certificate by certified mail to the Warrant Holder.

                                       69

SECTION 8.    SUBDIVISION OF WARRANT

              At the request of the Warrant Holder in connection with a
transfer of a portion of this Warrant upon surrender of this Warrant for such

SECTION 10.   REPRESENTATIONS AND WARRANTIES

              10.1   BY WARRANT HOLDER

              The Warrant Holder represents and warrants to the Company as
follows:

              (a)    This Warrant and the Warrant Shares issuable upon
exercise thereof are being acquired for the Warrant Holder's own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Securities
Act.  Upon exercise of this Warrant, the Warrant Holder shall, if so
requested by the Company, confirm in writing, in a form satisfactory to the
Company, that the securities issuable upon exercise of this Warrant are being
acquired for investment and not with a view toward distribution or resale.

              (b)    The Warrant Holder understands that the Warrant and the
Warrant Shares have not been registered under the Securities Act by reason of
their issuance in a transaction exempt from the registration and prospectus
delivery requirements of the Act pursuant to Section 4(2) or Section 4(6)
thereof, and that they must be held by the Warrant Holder indefinitely, and
that the Warrant Holder must therefore bear the economic risk of such
investment indefinitely, unless a subsequent disposition thereof is
registered under the Securities Act or is exempted from such registration.

              (c)    The Warrant Holder has such knowledge and experience in
financial and business matters that the Warrant Holder is capable of
evaluating the merits and risks of the purchase of this Warrant and the
Warrant Shares purchasable pursuant to the terms of this Warrant and of
protecting the Warrant Holder's interests in connection therewith.  The
Warrant Holder is an accredited investor, as such term is defined in Rule 501
of Regulation D promulgated pursuant to the 1984 Act.

                                       70

purchase of the Warrant Shares pursuant to the terms of this Warrant.

Act covering the proposed transfer, the holder thereof shall give written notice
to the Company of such holder's intention to effect such transfer, sale,
assignment or pledge.  Each such notice shall describe the manner and
circumstances of the proposed transfer, sale, assignment or pledge in sufficient
detail, and shall be accompanied, at such holder's expense by either (i) written
opinion of legal counsel who shall be, and whose legal opinion shall be,
reasonably satisfactory to the Company addressed to the Company, to the effect
that the proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act, or (ii) a "no action" letter from the
Commission to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by the holder to the
Company.  It is agreed that the Company will not request an opinion of counsel
for the holder for transactions made in reliance on Rule 144 under the
Securities Act except in unusual circumstances, the existence of which shall be
promptly determined in good faith by the Board of Directors of the Company.
Each certificate evidencing the Restricted Securities transferred as above
provided shall bear, except if such transfer is made pursuant to Rule 144, the
appropriate restrictive legend set forth in SECTION 3 above, except that such
certificate shall not bear such restrictive legend if in the opinion of counsel
for such holder (if required above) and the Company such legend is not required
in order to establish compliance with any provision of the Securities Act.

          5.   REGISTRATION.

          5.1  REQUESTED REGISTRATION.

               (i)  REQUEST FOR REGISTRATION.  If the Company shall receive from

                         its reasonable best efforts to promptly effect such

                         without limitation, appropriate qualification under
                         applicable blue sky or other state securities laws and
                         appropriate compliance with applicable regulations
                         issued under the Securities Act and any other
                         governmental requirements or regulations) as may be so
                         requested and as would permit or facilitate the sale
                         and distribution of all or such portion of such
                         Registrable Securities as are specified in such
                         request, together with all or such portion of the
                         Registrable Securities of any Holder or Holders joining
                         in such request as are specified in a written request
                         received by the Company within fifteen (15) days after
                         receipt of such written notice from the Company;

PROVIDED, HOWEVER, that the Company shall not be obligated to take any action to
effect any such registration, qualification or compliance pursuant to this
SECTION 5.1:

                         (a)  In any particular jurisdiction in which the
                              Company would be required to execute a general
                              consent to service of process in effecting such
                              registration, qualification or compliance unless
                              the Company is already subject to service in such
                              jurisdiction and except as may be required by the
                              Securities Act;

                         (b)  Prior to nine months from the date hereof;

                         (c)  After the Company has effected one such
                              registration pursuant to this SUBPARAGRAPH 5.1,
                              and such registration has been declared or ordered
                              effective and has remained effective until the
                              earlier to occur of ninety (90) days or the sale
                              of all of the securities offered pursuant to such
                              registration;

                         (d)  If the Company shall furnish to such Initiating
                              Holders a certificate signed by the Chief
                              Executive Officer of the Company stating that in
                              the good faith judgment of the Board of Directors,
                              it would be seriously detrimental to the Company
                              or its stockholders for a registration statement
                              to be filed in the near future, then the Company's
                              obligation to use its best efforts to register,
                              qualify or comply

                              under this SECTION 5.1 shall be deferred for a
                              period not to exceed ninety (90) days from the
                              date of receipt of written request from the
                              Initiating Holders, provided that the Company
                              may not exercise this deferral right more than
                              once per twelve (12) month period.  Subject to
                              the foregoing clauses, the Company shall file a
                              registration statement covering the Registrable
                              Securities so requested to be registered as
                              soon as practicable after receipt of the
                              request or requests of the Initiating Holders;

               (ii) UNDERWRITING.  If the Initiating Holders intend to
                    distribute the Registrable Securities covered by their
                    request by means of an underwriting, they shall so advise
                    the Company as a part of their request made pursuant to
                    SECTION 5.1(i), and the Company shall include such
                    information in the written notice given pursuant to SECTION
                    5.1(i).  The managing underwriter will be selected by a
                    majority in interest of the Initiating Holders, provided
                    that such managing underwriter is reasonably acceptable to
                    the Company.  In such event, the right of any Holder to
                    include his or her Registrable Securities in such
                    registration shall be conditioned upon such Holder's
                    participation in such underwriting and the inclusion of such
                    Holder's Registrable Securities in the underwriting (unless
                    otherwise mutually agreed by a majority in interest of the
                    Initiating Holders and such Holder) to the extent provided
                    herein.

          The Company shall (together with all Holders proposing to distribute
their securities through such underwriting) enter into an underwriting agreement
in customary form with the managing underwriter.  Notwithstanding any other
provision of this SECTION 5.1, if the managing underwriter advises the
Initiating Holders in writing that marketing factors require a limitation of the
number of shares to be underwritten, then the Company shall so advise all
Holders of Registrable Securities, and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
allocated among all Holders in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities held by such Holders at the time of
filing the registration statement.  Neither the Company nor any other holders of
Company securities may participate in the proposed offering if any Holders have
been cut back pursuant to this SECTION 5.1(ii).  No Registrable Securities
excluded from the underwriting by reason of the underwriter's marketing
limitation shall be included in such registration.  To facilitate the allocation
of shares in accordance with the above provisions, the Company or the
underwriters may round the number of shares allocated to any Holder to the
nearest 100 shares.

          If any Holder of Registrable Securities disapproves of the terms of
the underwriting, such person may elect to withdraw therefrom by written notice
to the Company, the managing underwriter and the Initiating Holders.  The
Registrable Securities and/or other

securities so withdrawn shall also be withdrawn from registration, and such
Registrable Securities shall continue to be subject to the terms of this
Agreement including SECTION 6 hereof.

          5.2  COMPANY REGISTRATION.

               (a)  NOTICE OF REGISTRATION.  If at any time, or from time to
time, the Company shall determine to register any of its equity securities,
either for its own account or the account of a security holder or holders, other
than (i) a registration relating solely to employee benefit plans, (ii) a
registration relating solely to a Rule 145 transaction, the Company will:

                    (1)  promptly give to each Holder written notice thereof;
                         and

                    (2)  include in such registration (and any related
                         qualification under blue sky laws or other compliance),
                         and in any underwriting involved therein, all the
                         Registrable Securities specified in a written request
                         or requests, made within twenty (20) days after receipt
                         of such written notice from the Company, by any Holder.

               (b)  UNDERWRITING.  If the registration of which the Company
gives notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to SECTION 5.2(a)(i).  In such event the right of any Holder to
registration pursuant to this SECTION 5.2 shall be conditioned upon such
Holder's participation in such underwriting, and the inclusion of Registrable
Securities in the underwriting shall be limited to the extent provided herein.

          All Holders proposing to distribute their securities through such
underwriting shall (together with the Company and the other holders distributing
their securities through such underwriting) enter into an underwriting agreement
in customary form with the managing underwriter selected for such underwriting
by the Company.  Notwithstanding any other provision of this SECTION 5.2, if the
managing underwriter determines that marketing factors require a limitation of
the number of shares to be underwritten, the managing underwriter may exclude
some or all of the Registrable Securities, or securities of other holders of
registration rights other than persons exercising demand registration rights,
from such registration.  The Company shall advise all Holders, and other holders
distributing their securities through such underwriting of any limits imposed on
their participation in the underwriting as provided in this SECTION 5.2(b).  The
number of shares of Registrable Securities, or securities of other holders of
registration rights other than persons exercising demand registration rights,
that may be included in the registration and underwriting in accordance with
this SECTION 5.2(b) shall be allocated among all the Holders and such other
holders of securities not exercising demand registration rights pro rata.

          If any Holder or other holder disapproves of the terms of any such
underwriting, he or she may elect to withdraw therefrom by written notice to the
Company and the managing underwriter.  Any securities excluded or withdrawn from
such underwriting shall be withdrawn


                                       7
<PAGE>


from such registration, and shall continue to be subject to the terms of this
Agreement, including SECTION 6 hereof. Furthermore,

                    (i)  No shareholder of the Company shall be granted any
                         rights superior to those granted to the Preferred
                         Stockholders pursuant to this SECTION 5.2 without the
                         prior consent of more than Fifty-One Percent (51%) of
                         (i) the then outstanding shares of Preferred Stock plus
                         (ii) if some or all of the Preferred has been converted
                         into Common Stock, the Conversion Stock issued pursuant
                         to such conversion and Shares underlying the Warrants.

                    (ii) RIGHT TO TERMINATE REGISTRATION.  The Company shall
                         have the right to terminate or withdraw any
                         registration initiated by it under this SECTION 5.2
                         prior to the effectiveness of such registration whether
                         or not any Holder has elected to include securities in
                         such registration.

          5.3  REGISTRATION ON FORM S-3.

               (a)  If any Holder or Holders of at least Five Percent (5%) of
the then outstanding Registrable Securities request that the Company file a
registration statement on Form S-3 (or any successor form to Form S-3) for a
public offering of all or some of the shares of the Registrable Securities held
by such Holder or Holders and the reasonably anticipated aggregate price to the
public of which, net of underwriting discounts and commissions, would exceed
FIVE HUNDRED THOUSAND DOLLARS ($500,000), and the Company is a registrant
entitled to use Form S-3 to register the Registrable Securities for such an
offering, the Company shall use its best efforts to cause such Registrable
Securities to be registered for the offering on such form and to cause such
Registrable Securities to be qualified in such jurisdictions as such Holder or
Holders may reasonably request.  The Company shall inform other Holders of the
proposed registration and offer them the opportunity to participate.  In the
event the registration is proposed to be part of a firm commitment underwritten
public offering, the substantive provisions of SECTION 5.1(ii) shall be
applicable to each such registration initiated under this SECTION 5.3.  The
Company may include other shares of Common Stock in any of the registrations
provided for in this SECTION 5.3, provided that such inclusion will not
interfere with the marketing (including the price to the public) of the
Registrable Securities to be registered by the Holders.

               (b)  Notwithstanding the foregoing, the Company shall not be
obligated to take any action pursuant to this SECTION 5.3 if any of the
conditions in Section 5.1(a), (b) or (d) exist or to Blue-Sky in a jurisdiction
where in the good faith judgment of the Board of Directors, it would be
unreasonably burdensome to qualify.

          5.4  EXPENSES OF REGISTRATION.  Registration Expenses incurred in
connection with (i) up to one requested registrations pursuant to SECTION 5.1,
(ii) all company registrations


                                       8


<PAGE>


pursuant to SECTION 5.2, and (iii) all Form S-3 registrations pursuant to
SECTION 5.3 shall be borne by the Company.  Selling Expenses shall be borne
by the selling shareholders incurring such expenses.

          5.5  REGISTRATION PROCEDURES.  In the case of each registration,
qualification or compliance effected by the Company pursuant to this Agreement,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof.  At its expense, the Company will:

               (a)  Prepare and file with the Commission a registration
statement with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for at least ninety (90)
days or until the distribution described in the registration statement has been
completed, whichever first occurs; PROVIDED, HOWEVER, that (i) such 90-day
period shall be extended for a period of time equal to the period the Holder
refrains from selling any securities included in such registration at the
request of an underwriter of Common Stock (or other securities) of the Company;
and (ii) in the case of any registration of Registrable Securities on Form S-3
which are intended to be offered on a continuous or delayed basis, such 90-day
period shall be extended up to a maximum total period of one year, if necessary,
to keep the registration statement effective until all such Registrable
Securities are sold, provided that Rule 415, or any successor rule under the
Securities Act, permits an offering on a continuous or delayed basis, and
provided further that applicable rules under the Securities Act governing the
obligation to file a post-effective amendment permit, in lieu of filing a
post-effective amendment which (I) includes any prospectus required by Section
10(a)(3) of the Act or (II) reflects facts or events representing a material or
fundamental change in the information set forth in the registration statement,
the incorporation by reference of information required to be included in (I) and
(II) above to be contained in periodic reports filed pursuant to Section 13 or
15 (d) of the Securities Exchange Act of 1934 (the "1934 ACT") in the
registration statement.

               (b)  Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Act with respect to the disposition of all securities covered
by such registration statement.

               (c)  Furnish to the Holders participating in such registration
and to the underwriters of the securities being registered such reasonable
number of copies of the registration statement, preliminary prospectus, final
prospectus and such other documents (including amendments or supplements
thereto) as such Holders or underwriters may reasonably request in order to
facilitate the public offering of such securities.

               (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders;
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general


                                       9
<PAGE>


consent to service of process in any such states or jurisdiction, unless the
Company is already subject to service in such jurisdiction.  Furthermore,

                    (i)    In the event of any underwritten public offering,
                           enter into and perform its obligations under an
                           underwriting agreement, in usual and customary form,
                           with the managing underwriter of such offering.  Each
                           Holder participating in such underwriting shall also
                           enter into and perform its obligations under such an
                           agreement.

                    (ii)   Notify each Holder of Registrable Securities covered
                           by such registration statement at any time when a
                           prospectus relating thereto is required to be
                           delivered under the Act of the happening of any event
                           as a result of which the prospectus included in such
                           registration statement, as then in effect, includes
                           an untrue statement of a material fact or omits to
                           state a material fact required to be stated therein
                           or necessary to make the statements therein not
                           misleading in the light of the circumstances then
                           existing and as promptly as practicable amend or
                           supplement the prospectus to correct such
                           misstatement or omission.

                    (iii)  Cause all such Registrable Securities registered
                           pursuant hereunder to be listed on each securities
                           exchange on which similar securities issued by the
                           Company are then listed.

                    (iv)   Provide a transfer agent and registrar for all
                           Registrable Securities registered pursuant hereunder
                           and a CUSIP number for all such Registrable
                           Securities, in each case not later than the effective
                           date of such registration.

                    (v)    Furnish, at the request of any Holder requesting
                           registration of Registrable Securities pursuant to
                           this SECTION 5.5, on the date that such Registrable
                           Securities are delivered to the underwriters for sale
                           in connection with a registration pursuant to this
                           SECTION 5.5, if such securities are being sold
                           through underwriters, (i) an opinion, dated such
                           date, of the counsel representing the Company for the
                           purposes of such registration, in form and substance
                           as is customarily given to underwriters in an
                           underwritten public offering, addressed to the
                           underwriters, and (ii) a letter dated such date, from
                           the independent certified public accountants of the
                           Company, in form and substance as is customarily
                           given by independent certified public accountants to


                                       10
<PAGE>


                           underwriters in an underwritten public offering,
                           addressed to the underwriters.

                    (vi)   In the event of any underwritten public offering,
                           cooperate with the Holders requesting registration
                           pursuant to this Section, the underwriters
                           participating in the offering and their counsel in
                           any due diligence investigation reasonably requested
                           by the Holders or the underwriters in connection
                           therewith, and participate, to the extent reasonably
                           requested by the managing underwriter for the
                           offering or the Holders, in efforts to sell the
                           Registrable Securities under the offering (including
                           without limitation, participating in "roadshow"
                           meetings with prospective investors) that would be
                           customary for underwritten primary offerings of a
                           comparable amount of equity securities by the
                           Company.

          5.6  INDEMNIFICATION.

               (a)  The Company will indemnify each Holder, each of such
Holder's officers, directors, members, partners, legal counsel and agent, and
each person controlling such Holder within the meaning of Section 15 of the
Securities Act, with respect to which registration, qualification or compliance
has been effected pursuant to this Agreement, and each underwriter, if any, and
each person who controls any underwriter within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages or liabilities (or
actions in respect thereof), including any of the foregoing incurred in
settlement of any litigation, commenced or threatened, arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any registration statement, prospectus, offering circular or other
document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance, or based on 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 or any violation by the
Company of the Securities Act of 1933, the Securities Exchange Act of 1934,
state securities law or any rule or regulation promulgated under such laws
applicable to the Company in connection with any such registration,
qualification or compliance, and the Company will reimburse each such Holder,
each of such Holder's officers and directors, and members, partners, legal
counsel, agents and each person controlling such Holder, each such underwriter
and each person who controls any such underwriter, for any legal and any other
expenses reasonably incurred, as such expenses are incurred, in connection with
investigating, preparing or defending of any such claim, loss, damage, liability
or action, provided that the Company will not be liable in any such case to the
extent that any such claim, loss, damage, liability or expense arises out of or
is based on any untrue statement or omission or alleged utrue statement or
omission, made in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder,
controlling person or underwriter and stated to be specifically for use therein.


                                       11
<PAGE>


               (b)  Each Holder severally, and not jointly will, if Registrable
Securities held by such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify the
Company, each of its directors and officers, each underwriter, if any, of the
Company's securities covered by such a registration statement, each person who
controls the Company or such underwriter within the meaning of Section 15 of the
Securities Act, and each other such Holder, each of such Holder's officers and
directors and each person controlling such Holder within the meaning of Section
15 of the Securities Act, against all claims, losses, damages and liabilities
(or actions in respect thereof) arising out of or based on any untrue statement
(or alleged untrue statement) of a material fact contained in any such
registration statement, prospectus, offering circular or other document, or 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, and
will reimburse the Company, such Holders, such directors, officers, persons,
underwriters or control persons for any legal or any other expenses reasonably
incurred, as such expenses are incurred, in connection with investigating or
defending any such claim, loss, damage, liability or action, in each case to the
extent, but only to the extent, that such untrue statement (or alleged untrue
statement) or omission (or alleged omission) is made in such registration
statement, prospectus, offering circular or other document in reliance upon and
in conformity with written information furnished to the Company by an instrument
duly executed by such Holder and stated to be specifically for use therein.  Not
withstanding the foregoing, the liability of each Holder under this
SUBSECTION 5.6(b) shall be limited in an amount equal to the net proceeds
received from the sale of the shares sold by such Holder.

               (c)  Each party entitled to indemnification under this SECTION
5.6 (the "INDEMNIFIED PARTY") shall give notice to the party required to provide
indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Agreement unless the failure to give such notice is
materially prejudicial to an Indemnifying Party's ability to defend such action
and provided further, that the Indemnifying Party shall not assume the defense
for matters as to which there is a conflict of interest or separate and
different defenses.  No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation or which includes an admission of fault on behalf of the Indemnified
Party.

               (d)  If the indemnification provided for in this SECTION 5.6 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or expense referred to
therein, then the Indemnifying Party, in lieu of


                                       12
<PAGE>


indemnifying such Indemnified Party hereunder, shall to the extent permitted
by applicable law contribute to the amount paid or payable by such
Indemnified Party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party on the one hand and of the Indemnified Party on the
other in connection with the statements or omissions that resulted in such
loss, liability, claim, damage, or expense as well as any other relevant
equitable considerations.  The relative fault of the indemnifying party and
of the Indemnified Party shall be determined by a court of law by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission to state a material fact relates to the
information supplied by the Indemnifying Party or by the Indemnified Party
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.
Notwithstanding the foregoing, the amount to be contributed by any Holder
under this SECTION 5.6(d) shall be limited to an amount equal to the net
proceeds received from the sale of the shares sold by such Holder.

               (e)  Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

               (f)  The obligations of the Company and the Holders under this
SECTION 5.6 shall survive completion of any offering of Registrable Securities
in a registration statement and the termination of this Agreement.  No
Indemnifying Party shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to each Indemnified Party of a release from all liability in respect to such
claim or litigation; provided, that no Indemnified Party shall consent to entry
of any judgment or enter into any settlement without the consent of Indemnifying
Party.  No person guilty of fraudulent misrepresentations (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who is not guilty of such fraudulent misrepresentation.

          5.7  INFORMATION BY HOLDER.  The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders, the Registrable Securities held by
them and the distribution proposed by such Holder or Holders as the Company may
request in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Agreement.

          5.8  RULE 144 REPORTING.  With a view to making available the benefits
of certain rules and regulations of the Commission which may at any time permit
the sale of the Restricted Securities to the public without registration, the
Company agrees to use all reasonable efforts to:

               (a)  Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the effective date


                                       13
<PAGE>


that the Company becomes subject to the reporting requirements of the
Securities Act or the 1934 Act;

               (b)  File with the Commission in a timely manner all reports and
other documents required of the Company under the Securities Act and the 1934
Act (at any time after it has become subject to such reporting requirements);
and

               (c)  So long as the Holder owns any Restricted Securities to
furnish to the Holder forthwith upon request a written statement by the Company
as to its compliance with the reporting requirements of said Rule 144 (at any
time after ninety (90) days after the effective date of the first registration
statement filed by the Company for an offering of its securities to the general
public), and of the Securities Act and the 1934 Act (at any time after it has
become subject to such reporting requirements), a copy of the most recent annual
or quarterly report of the Company, and such other reports and documents of the
Company and other information in the possession of or reasonably obtainable by
the Company as the Holder may reasonably request in availing itself of any rule
or regulation of the Commission allowing the Holder to sell any such securities
without registration.

          5.9  TRANSFER OF REGISTRATION RIGHTS.  The rights to cause the Company
to register securities granted to the Holders under SECTIONS 5.1, 5.2 and 5.3
may be assigned to a transferee or assignee in connection with (a) any transfer
or assignment of Fifty Thousand (50,000) (as adjusted for stock splits, stock
dividends, recapitalizations and the like) or more shares of Registrable
Securities by the Holder to one or more persons in a single transaction or
series of related transactions, provided that (i) the Company is given notice
thereof and the transferee covenants to be bound by the provisions of this
Agreement and (ii) such transfer may otherwise be affected in accordance with
applicable securities laws or (b) any transfer or assignment of Registrable
Securities by the Holder to partners, members or affiliates of such Holder.

          5.10 SUBSEQUENT REGISTRATION RIGHTS.  From and after the date of this
Agreement, the Company shall not grant any registration rights to subsequent
purchasers of the Company's equity securities that are, in the good faith

Securities.

observance thereof may be waived (either generally or in a particular instance
and either retroactively or prospectively), only with the written consent of the
Company and the holders of not less than a majority of the Registrable
Securities then outstanding. Any amendment or waiver effected in accordance with
this SECTION 6 shall be binding upon each Preferred Stockholder and each Holder
of Registrable Securities at the time outstanding (including securities into
which such securities are convertible), each future holder of all such
securities, and the Company.

                              CONVERSION AGREEMENT

         THIS AGREEMENT is entered into effective November ____, 1999, by and
among SOLIGEN TECHNOLOGIES, INC., a Wyoming corporation (the "Company"), the
undersigned holders ("Holders") of the Company's Series A Convertible Preferred
Stock ("Series A Preferred").

                                    RECITALS

         WHEREAS, the Company proposes to complete a Series B Convertible
Preferred Stock ("Series B Stock") and common stock warrant financing (the
"Series B Financing"); and

         WHEREAS, certain of the Holders and other parties advised by ICM Asset
Management, Inc. (collectively, the "Holder Parties") propose to invest a
cumulative total of Two Hundred Fifty Thousand Dollars ($250,000) in the Series
B Financing; and

         WHEREAS, in accordance with the terms of this Agreement, the Holders
are willing to, among other things, convert all outstanding shares of the
Company's Series A Preferred into the Company's Common Stock ("Common Stock")
concurrent to the completion of the Series B Financing; and

         WHEREAS, notwithstanding the Holder Parties' investment in the Series B
Financing, the Holders also desire (a) to waive their right to require the
Company's compliance with the right of first refusal provisions set forth in
Section 2 of that certain Investor Rights Agreement, dated April 24, 1998, as
amended by and among the Holders and the Company ("Investor Rights Agreement")
in connection with the Series B Financing, and (b) to amend certain provisions
of the Investor Rights Agreement;

         NOW, THEREFORE, in consideration of the mutual promises and covenants
hereinafter set forth, all parties hereto agree as follows:

                                    AGREEMENT

1.       CONVERSION.

         In accordance with Subsection 9(b)(iii) of the Company's Articles of
Continuance, as amended, each Holder hereby gives notice of conversion of all of
the shares of the Company's Series A Preferred now held by such Holder. The
number of shares of Common Stock to be issued upon conversion ("Conversion
Shares") is as set forth on SCHEDULE 1 attached hereto and incorporated herein
by this reference. Such conversion shall be made effective concurrent with, and
contingent upon, the completion of the Series B Financing. If the Series B
Financing is not


<PAGE>


completed on or before December 15, 1999, then this conversion notice and
request shall be deemed withdrawn and of no further force or effect.

2.       ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK.

         In consideration of the agreement of the Holders to convert as set
forth in Section 1 above, the Company shall issue to each Holder, in addition to
the shares issuable upon conversion of Series A Preferred, that number of
additional shares of Common Stock set forth on SCHEDULE 1 attached hereto and
included herein by this reference ("Additional Shares"). The date of issuance of
the Additional Shares shall be the date on which the Series A Preferred are
converted in accordance with this Agreement. The Additional Shares will be
included in that certain Investor Rights Agreement dated November 24, 1999, by
and between the Company and purchasers of Series B Stock in the Series B
Financing.

3.       REPRESENTATIONS AND WARRANTIES OF HOLDERS. Each Holder represents and
warrants to the Company as follows:

         3.1      The Additional Shares will be acquired by the Holder for
investment for the Holder's own account and not with a view to the distribution
of any part thereof, and the Holder has no present intention of selling,
granting any participation in, or otherwise distributing the same in a manner
contrary to the applicable federal and state securities laws.

         3.2      Each Holder is an investor in securities of companies in the
development stage and qualifies as an "accredited investor" as defined in Rule
501 of Regulation D promulgated by the Securities and Exchange Commission
("SEC"). Each Holder is able to fend for itself in the transactions contemplated
by this Agreement and has such knowledge and experience in financial or business
matters that it is capable of evaluating the merits and risks of its investment
in the Additional Shares. Each Holder understands that the Additional Shares
have not been registered under the applicable securities laws, or under the
securities laws of any jurisdiction, by reason of reliance upon certain
exemptions, and that the reliance of the Company on such exemptions is
predicated upon the accuracy of the Holders' representations and warranties in
this SECTION 3.

         3.3      Each Holder understands that the Additional Shares are
characterized as "restricted securities" inasmuch as they are being acquired
from the Company in a transaction not involving a public offering, and that
under applicable laws and regulations, such securities may be transferred or
resold without registration only in certain limited circumstances and in
accordance with the terms and conditions set forth in the legend described in
SECTION 4. In this connection, each Holder represents that it is familiar with
SEC Rule 144, as presently in effect, and understands the resale limitations
imposed thereby and by the applicable securities laws.

         3.4      For purposes of the application of state securities laws, each
Holder represents that it is a resident of the State of Washington.

4.       LEGENDS.

         The certificates evidencing the Additional Shares shall bear the
following legend:

SECTION 2.  DURATION AND EXERCISE OF WARRANT

                  2.1      EXERCISE PERIOD

                  Subject to the provisions hereof, this Warrant may be
exercised at any time and from time to time during the period commencing on the
Initial Exercise Date and ending on the Expiration Date. After the Expiration
Date, this Warrant shall become void and all rights to purchase Warrant Shares

                  2.2      METHOD OF EXERCISE AND PAYMENT

                  (a)      METHOD OF EXERCISE. Subject to Section 2.1 hereof and
compliance with all applicable Federal and state securities laws, the purchase
right represented by this Warrant may be exercised, in whole or in part, by the
Warrant Holder by (i) surrender of this Warrant and delivery of an exercise form
specifying the number of shares to be purchased, duly executed, at the principal
office of the Company and (ii) payment to the Company of an amount equal to the
product of the then applicable Exercise Price multiplied by the number of
Warrant Shares then being purchased. At the election of the Warrant holder, the
purchase price may be paid by surrender of this Warrant for the full number of
shares for which this Warrant is then exercisable less that number of shares
having a fair market value equal to the aggregate exercise price. For purposes
of this Section, fair market value shall be determined as follows: if the Common
Shares are then traded on the over-the-counter market on the date in question,
the last reported per-share sales price; provided that if there have been no
sales reported in the most recent two trading days at the time of determination,

SECTION 3.        VALIDITY AND RESERVATION OF WARRANT SHARES

                  The Company represents and warrants that all Warrant Shares
issued upon exercise of this Warrant will be validly issued, fully paid,
nonassessable and not subject to preemptive or similar rights. The Company
agrees that, as long as this Warrant may be exercised, the Company will have
authorized and reserved for issuance upon exercise of this Warrant a sufficient
number of shares of Common Stock to provide for exercise in full of this
Warrant.

SECTION 4.        FRACTIONAL SHARES

                  No fractional Warrant Shares shall be issued upon the exercise
of this Warrant, and the number of Warrant shares to be issued shall be rounded
to the nearest whole number.

SECTION 5.        LIMITED RIGHTS OF WARRANT HOLDER

                  The Warrant Holder shall not, solely by virtue of being the
Warrant Holder of this Warrant, have any of the rights of a stockholder of the
Company, either at law or equity, until this Warrant shall have been exercised.

SECTION 6.        LOSS OF WARRANT

                  Upon receipt by the Company of satisfactory evidence of the
loss, theft, destruction or mutilation of this Warrant and either (in the case
of loss, theft or destruction) reasonable indemnification and a bond
satisfactory to the Company if requested by the Company or (in the case of
mutilation) the surrender of this Warrant for cancellation, the Company will
execute and deliver to the Warrant Holder, without charge, a new warrant of like
denomination.

SECTION 7.        CERTAIN ADJUSTMENTS OF EXERCISE PRICE

                  7.1      ADJUSTMENT OF EXERCISE PRICE

                  The number, class and Exercise Price of securities for which
this Warrant may be exercised are subject to adjustment from time to time upon
the happening of certain events as hereinafter provided:

                  (a)      RECAPITALIZATION. If the outstanding shares of the
Company's Common Stock are divided into a greater number of shares or the
Company issues a stock dividend on its outstanding Common Stock, the number of
shares of Common Stock purchasable upon the exercise of this Warrant shall be
proportionately increased and the Exercise Price shall be proportionately
reduced and, conversely, if the outstanding shares of Common Stock are combined
into a smaller number of shares of Common Stock, the number of shares of Common
Stock purchasable upon the exercise of this Warrant shall be proportionately
reduced and the Exercise Price shall be proportionately increased. The increases
and reductions provided for in this Section 7.1.(a) shall be made with the
intent and, as nearly as practicable, the effect that

                                       4

<PAGE>

neither the percentage of the total equity of the Company obtainable on
exercise of this Warrant nor the price payable for such percentage shall be
affected by any event described in this Section 7.1 (a).

                  (b)      MERGER OR REORGANIZATION, ETC. In the event of any
change in the Common Stock through merger, consolidation, reclassification,
reorganization (such as, but not limited to, spin-offs of a business whereby,
for example, a Company asset is contributed to a subsidiary which is then
spun-off to the Company's shareholders), partial or complete liquidation or
other change in the capital structure of the Company (not including the issuance
of additional shares of capital stock other than by stock dividend or stock
split), then, as a condition of such change in the capital structure of the
Company, appropriate and adequate provision shall be made so that the Warrant
Holder of this Warrant will have the right thereafter to receive upon the
exercise of this Warrant the kind and amount of shares of stock or other
securities or property to which it would have been entitled if immediately prior
to such merger, consolidation, reclassification, reorganization,
recapitalization or other change in the capital structure, it had held the
number of shares of Common Stock then obtainable upon the exercise of this
Warrant. In any such case appropriate adjustment shall be made in the
application of the provisions set forth herein with respect to the rights and
interest thereafter of the Warrant Holder, to the end that the provisions set
forth herein shall thereafter be applicable, as nearly as reasonably may be, in
relation to any shares of stock or other property thereafter deliverable upon
the exercise of this Warrant.

                  (c)      Reference is made to Section 9 (c) (iii) (d) of the
Amendment to Articles. It is agreed that if pursuant to said section of the
Amendment to Articles, the Series B Conversion ratio is required to be adjusted,
this Warrant shall likewise be adjusted on a proportional and similar basis as
the Series B Preferred Stock is adjusted.

                  7.2      NOTICE OF ADJUSTMENT

                  Whenever an event occurs requiring any adjustment to be made
pursuant to Section 7.1(a), 7.1(b) or (c), the Company shall promptly file with
its Secretary or an Assistant Secretary at its principal office and with its
stock transfer agent, if any, a certificate of its chief executive officer
specifying such adjustment, setting forth in reasonable detail the acts
requiring such adjustment, and stating such other facts as shall be necessary to
show the manner and figures used to compute such adjustment. Such chief
executive officer's certificate shall be made available at all reasonable times
for inspection by the Warrant Holder. Promptly (but in no event more than 30
days) after each such adjustment, the Company shall give a copy of such
certificate by certified mail to the Warrant Holder.

                                       5

SECTION 8.        SUBDIVISION OF WARRANT

                  At the request of the Warrant Holder in connection with a
transfer of a portion of this Warrant upon surrender of this Warrant for such
purpose to the Company at its principal office, the Company at its expense
(except for any transfer tax payable) will issue and exchange therefor new
Warrants of like tenor and date representing in the aggregate the amount of the
Warrant Shares.

SECTION 9.        REGISTRATION RIGHTS

                  The Initial Warrant Holder shall have all the registration
rights provided in that certain Investor Rights Agreement entered into
concurrently herewith pursuant to the Series B Stock and Warrant Purchase
Agreement, including the right to transfer such rights to a subsequent Holder
subject to the terms and conditions set forth in the Investor Rights Agreement..

SECTION 10.       REPRESENTATIONS AND WARRANTIES

                  10.1     BY WARRANT HOLDER

                  The Warrant Holder represents and warrants to the Company as
follows:

                  (a)      This Warrant and the Warrant Shares issuable upon
exercise thereof are being acquired for the Warrant Holder's own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Securities
Act. Upon exercise of this Warrant, the Warrant Holder shall, if so requested by
the Company, confirm in writing, in a form satisfactory to the Company, that the
securities issuable upon exercise of this Warrant are being acquired for
investment and not with a view toward distribution or resale.

                  (b)      The Warrant Holder understands that the Warrant and
the Warrant Shares have not been registered under the Securities Act by reason
of their issuance in a transaction exempt from the registration and prospectus
delivery requirements of the Act pursuant to Section 4(2) or Section 4(6)
thereof, and that they must be held by the Warrant Holder indefinitely, and that
the Warrant Holder must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Securities Act or is exempted from such registration.

                  (c)      The Warrant Holder has such knowledge and experience
in financial and business matters that the Warrant Holder is capable of
evaluating the merits and risks of the purchase of this Warrant and the Warrant
Shares purchasable pursuant to the terms of this Warrant and of protecting the
Warrant Holder's interests in connection therewith. The Warrant Holder is an
accredited investor, as such term is defined in Rule 501 of Regulation D
promulgated pursuant to the 1984 Act.

                                       6

<PAGE>

                  (d)      The Warrant Holder is able to bear the economic risk
of the purchase of the Warrant Shares pursuant to the terms of this Warrant.
