Item 5.  OTHER EVENTS

Equity Line Financing of up to $35 Million in Common Stock

On March 14, 2000, U.S. Microbics, Inc. (the "Company") entered into an
Investment Agreement (the "Investment Agreement") to sell up to $35,000,000 of
the Company's common stock to Swartz Private Equity, LLC ("Swartz"). As part of
the consideration for the Investment Agreement, the Company issued warrants to
Swartz to purchase an aggregate of 250,000 shares of Common Stock at an exercise
price of $ 2.00 per share. In addition, the Company will pay financial advisory
and finders' fees of $ 25,000 in connection with this equity line financing
arrangement.

The Company will not receive any proceeds related to this equity line financing
arrangement, until the SEC declares effective a registration statement covering
the shares to be issued and sold to Swartz.

Under the terms of the Investment Agreement:

     o    The Company periodically may choose to sell shares of its common stock
          ("Shares") to Swartz. If the Company elects to sell Shares to Swartz,
          then the purchase price for such Shares will be the lesser of (i)
          ninety-two percent (92%) of the lowest closing bid price (the "Market
          Price") for the Company's common stock during the thirty days
          following the date that the Shares are delivered to Swartz, or (ii)
          the Market Price minus $.10 per share.

     o    If the Company elects not to put Shares to Swartz, then it may be
          obligated to pay fees to Swartz of up to $100,000 every six months.

     o    If the Investment Agreement is terminated by the Company or by Swartz
          for certain enumerated reasons, including breach of the Investment
          Agreement by the Company, then the Company may be obligated to pay
          fees to Swartz of up to $200,000.

     o    Each time that the Company elects to sell Shares to Swartz, the
          Company is obligated to issue and deliver to Swartz a warrant to
          purchase a number of shares equal in value to fifteen percent (15%) of
          the Market Price of such Shares. The warrant is exercisable at one
          hundred ten percent (110%) of the Market Price for such Shares.

     o    The Company initially must register with the SEC 20,000,000 Shares in
          connection with this equity line. The Company will be obligated to pay
          a fee of $250 per day, for each day after April 28, 2000, until the
          Company files a registration statement covering such shares (the
          "Registration Statement") In addition, if the Company does not respond
          to any comments made by the SEC regarding the Registration Statement
          within 30 days of the date that it receives such comments, then the
          Company will be obligated to pay a fee to Swartz of $250 per day until
          the Company responds to such comments.

          2.3 Puts of Common Shares to the Investor.
              --------------------------------------

               2.3.1 Procedure to Exercise a Put. Subject to the Individual Put
Limit, the Maximum Offering Amount and the Cap Amount (if applicable), and the
other conditions and limitations set forth in this Agreement, at any time

<PAGE>

beginning on the date on which the Registration Statement is declared effective
by the SEC (the "Effective Date"), the Company may, in its sole and absolute
discretion, elect to exercise one or more Puts according to the following
procedure, provided that each subsequent Put Date after the first Put Date shall
be no sooner than five (5) Business Days following the preceding Pricing Period
End Date:

               (a) Delivery of Advance Put Notice. At least ten (10) Business
Days but not more than twenty (20) Business Days prior to any intended Put Date
(unless otherwise agreed in writing by the Investor), the Company shall deliver
advance written notice (the "Advance Put Notice," the form of which is attached
hereto as Exhibit E, the date of such Advance Put Notice being the "Advance Put
Notice Date") to Investor stating the Put Date for which the Company shall,
subject to the limitations and restrictions contained herein, exercise a Put and
stating the number of shares of Common Stock (subject to the Individual Put
Limit and the Maximum Put Dollar Amount) which the Company intends to sell to
the Investor for the Put (the "Intended Put Share Amount").

     The Company may, at its option, also designate in any Advance Put Notice
(i) a maximum dollar amount of Common Stock, not to exceed $2,000,000, which it
shall sell to Investor during the Put (the "Company Designated Maximum Put
Dollar Amount") and/or (ii) a minimum purchase price per Put Share at which the
Investor may purchase Shares pursuant to such Put Notice (a "Company Designated
Minimum Put Share Price"). The Company Designated Minimum Put Share Price, if
applicable, shall be no greater than 85% of the Closing Bid Price of the
Company's Common Stock on the Advance Put Notice Date. The Company may decrease
(but not increase) the Company Designated Minimum Put Share Price for a Put at
any time by giving the Investor written notice of such decrease not later than
12:00 Noon, New York City time, on the Business Day immediately preceding the
Business Day that such decrease is to take effect. A decrease in the Company
Designated Minimum Put Share Price shall have no retroactive effect on the
determination of Trigger Prices and Excluded Days for days preceding the
Business Day that such decrease takes effect.

     Notwithstanding the above, if, at the time of delivery of an Advance Put
Notice, more than two (2) Calendar Months have passed since the date of the
previous Put Closing, such Advance Put Notice shall provide at least twenty (20)
Business Days notice of the intended Put Date, unless waived in writing by the
Investor. In order to effect delivery of the Advance Put Notice, the Company
shall (i) send the Advance Put Notice by facsimile on such date so that such
notice is received by the Investor by 6:00 p.m., New York, NY time, and (ii)
surrender such notice on such date to a courier for overnight delivery to the
Investor (or two (2) day delivery in the case of an Investor residing outside of
the U.S.). Upon receipt by the Investor of a facsimile copy of the Advance Put
Notice, the Investor shall, within two (2) Business Days, send, via facsimile, a
confirmation of receipt (the "Advance Put Notice Confirmation," the form of
which is attached hereto as Exhibit F) of the Advance Put Notice to the Company
specifying that the Advance Put Notice has been received and affirming the
intended Put Date and the Intended Put Share Amount.

               (b) Put Share Amount. The "Put Share Amount" is the number of
shares of Common Stock that the Investor shall be obligated to purchase in a
given Put, and shall equal the lesser of (i) the Intended Put Share Amount, and
(ii) the Individual Put Limit. The "Individual Put Limit" shall equal the lesser
of (i) 15% of the sum of the aggregate daily reported Trading Volumes in the
outstanding Common Stock on the Company's Principal Market, excluding any block
trades of 20,000 or more shares of Common Stock, for all Evaluation Days (as
defined below) in the Pricing Period, (ii) the number of Put Shares which, when
multiplied by their respective Put Share Prices, equals the Maximum Put Dollar
Amount, and (iii) the 9.9% Limitation, but in no event shall the Individual Put
Limit exceed 15% of the sum of the aggregate daily reported Trading Volumes in
the outstanding Common Stock on the Company's Principal Market, excluding any
block trades of 20,000 or more shares of Common Stock, for the twenty (20)
Business Days immediately preceding the Put Date (this limitation, together with
the limitation in (i) immediately above, are collectively referred to herein as
the "Volume Limitations"). The Company agrees not to trade Common Stock or
arrange for Common Stock to be traded for the purpose of artificially increasing
the Volume Limitations.

     For purposes of this Agreement:

          "Trigger Price" for any Pricing Period shall mean the greater of (i)
the Company Designated Minimum Put Share Price, plus $.10, or (ii) the Company
Designated Minimum Put Share Price divided by .92.

<PAGE>


          An "Excluded Day" shall mean each Business Day during a Pricing Period
where the lowest intra-day trading price of the Common Stock is less than the
Trigger Price.

          An "Evaluation Day" shall mean each Business Day during a Pricing
Period that is not an Excluded Day.

               (c) Put Share Price. The purchase price for the Put Shares (the
"Put Share Price") shall equal the lesser of (i) the Market Price for such Put,
minus $.10, or (ii) 92% of the Market Price for such Put, but shall in no event
be less than the Company Designated Minimum Put Share Price for such Put, if
applicable.

               (d) Delivery of Put Notice. After delivery of an Advance Put
Notice, on the Put Date specified in the Advance Put Notice the Company shall
deliver written notice (the "Put Notice," the form of which is attached hereto
as Exhibit G) to Investor stating (i) the Put Date, (ii) the Intended Put Share
Amount as specified in the Advance Put Notice (such exercise a "Put"), (iii) the
Company Designated Maximum Put Dollar Amount (if applicable), and (iv) the
Company Designated Minimum Put Share Price (if applicable). In order to effect
delivery of the Put Notice, the Company shall (i) send the Put Notice by
facsimile on the Put Date so that such notice is received by the Investor by
6:00 p.m., New York, NY time, and (ii) surrender such notice on the Put Date to
a courier for overnight delivery to the Investor (or two (2) day delivery in the
case of an Investor residing outside of the U.S.). Upon receipt by the Investor
of a facsimile copy of the Put Notice, the Investor shall, within two (2)
Business Days, send, via facsimile, a confirmation of receipt (the "Put Notice
Confirmation," the form of which is attached hereto as Exhibit H) of the Put
Notice to Company specifying that the Put Notice has been received and affirming
the Put Date and the Intended Put Share Amount.

               (e) Delivery of Required Put Documents. On or before the Put Date
for such Put, the Company shall deliver the Required Put Documents (as defined
in Section 2.3.5 below) to the Investor (or to an agent of Investor, if Investor
so directs). Unless otherwise specified by the Investor, the Put Shares shall be
transmitted electronically pursuant to such electronic delivery system as the
Investor shall request; otherwise delivery shall be by physical certificates. If
the Company has not delivered all of the Required Put Documents to the Investor
on or before the Put Date, the Put shall be automatically cancelled, unless the
Investor agrees to delay the Put Date by up to three (3) Business Days, in which
case the Pricing Period begins on the Business Day following such new Put Date.
If the Company has not delivered all of the Required Put Documents to the
Investor on or before the Put Date (or new Put Date, if applicable), and the
Investor has not agreed in writing to delay the Put Date, the Put is
automatically canceled (an "Impermissible Put Cancellation") and, unless the Put
was otherwise canceled in accordance with the terms of Section 2.3.11, the
Company shall pay the Investor $5,000 for its reasonable due diligence expenses
incurred in preparation for the canceled Put and the Company may deliver an
Advance Put Notice for the subsequent Put no sooner than ten (10) Business Days
after the date that such Put was canceled, unless otherwise agreed by the
Investor.

               (f) Limitation on Investor's Obligation to Purchase Shares.
Notwithstanding anything to the contrary in this Agreement, in no event shall
the Investor be required to purchase, and an Intended Put Share Amount may not
include, an amount of Put Shares, which when added to the number of Put Shares
acquired by the Investor pursuant to this Agreement during the 31 days preceding
the Put Date with respect to which this determination of the permitted Intended
Put Share Amount is being made, would exceed 9.99% of the number of shares of
Common Stock outstanding (on a fully diluted basis, to the extent that inclusion
of unissued shares is mandated by Section 13(d) of the Exchange Act) on the Put
Date for such Pricing Period, as determined in accordance with Section 13(d) of
the Exchange Act (the "Section 13(d) Outstanding Share Amount"). Each Put Notice
shall include a representation of the Company as to the Section 13(d)
Outstanding Share Amount on the related Put Date. In the event that the Section
13(d) Outstanding Share Amount is different on any date during a Pricing Period
than on the Put Date associated with such Pricing Period, then the number of
shares of Common Stock outstanding on such date during such Pricing Period shall
govern for purposes of determining whether the Investor, when aggregating all
purchases of Shares made pursuant to this Agreement in the 31 calendar days
preceding such date, would have acquired more than 9.99% of the Section 13(d)
Outstanding Share Amount. The limitation set forth in this Section 2.3.1(f) is
referred to as the "9.9% Limitation."

          2.3.2 Termination of Right to Put. The Company's right to require the
Investor to purchase any subsequent Put Shares shall terminate permanently
(each, an "Automatic Termination") upon the occurrence of any of the following:

<PAGE>


               (a) the Company shall not exercise a Put or any Put thereafter
if, at any time, either the Company or any director or executive officer of the
Company has engaged in a transaction or conduct related to the Company that has
resulted in (i) an SEC enforcement action, or (ii) a civil judgment or criminal
conviction for fraud or misrepresentation, or for any other offense that, if
prosecuted criminally, would constitute a felony under applicable law;

               (b) the Company shall not exercise a Put or any Put thereafter,
on any date after a cumulative time period or series of time periods, including
both Ineffective Periods and Delisting Events, that lasts for an aggregate of
four (4) months;

               (c) the Company shall not exercise a Put or any Put thereafter if
at any time the Company has filed for and/or is subject to any bankruptcy,
insolvency, reorganization or liquidation proceedings or other proceedings for
relief under any bankruptcy law or any law for the relief of debtors instituted
by or against the Company or any subsidiary of the Company;

               (d) the Company shall not exercise a Put after the sooner of (i)
the date that is three (3) years after the Effective Date, or (ii) the Put
Closing Date on which the aggregate of the Put Dollar Amounts for all Puts equal
the Maximum Offering Amount;

               (e) the Company shall not exercise a Put after the Company has
breached any covenant in Section 2.6, Section 6, or Section 9 hereof, provided
that, if such breach is curable, then no Automatic Termination shall occur if
the Company has cured such breach within thirty (30) days of the first date on
which the Company becomes aware of such breach, provided further that, the
Company shall not be entitled to initiate any Puts prior to such cure;

               (f) if no Registration Statement has been declared effective by
the date that is one (1) year after the date of this Agreement, the Automatic
Termination shall occur on the date that is one (1) year after the date of this
Agreement; and

               (g) the Company shall not exercise a Put after any statement by
the SEC that the issuance of Put Shares to the Investor would constitute a
violation of Section 5 of the Act.


          2.3.3 Put Limitations. The Company's right to exercise a Put shall be
limited as follows:

               (a) notwithstanding the amount of any Put, the Investor shall not
be obligated to purchase any additional Put Shares once the aggregate Put Dollar
Amount paid by Investor equals the Maximum Offering Amount;

               (b) the Investor shall not be obligated to acquire and pay for
the Put Shares with respect to any Put for which the Company has announced a
subdivision or combination, including a reverse split, of its Common Stock or
has subdivided or combined its Common Stock during the Extended Put Period;

               (c) the Investor shall not be obligated to acquire and pay for
the Put Shares with respect to any Put for which the Company has paid a dividend
of its Common Stock or has made any other distribution of its Common Stock
during the Extended Put Period;

<PAGE>


               (d) the Investor shall not be obligated to acquire and pay for

evidences of indebtedness to the holders of its Common Stock;

               (e) the Investor shall not be obligated to acquire and pay for

               (b) the Company shall have satisfied any and all obligations

is required by the rules of such market.

          2.3.5 Documents Required to be Delivered on the Put Date as Conditions
to Closing of any Put. The Closing of any Put and Investor's obligations
hereunder shall additionally be conditioned upon the delivery to the Investor of
each of the following (the "Required Put Documents") on or before the applicable
Put Date:

               (a) a number of Unlegended Share Certificates (or freely
tradeable electronically delivered shares, as appropriate) equal to the Intended

          2.3.6 Accountant's Letter and Registration Opinion.

               (a) The Company shall have caused to be delivered to the
Investor, (i) whenever required by Section 2.3.6(b) or by Section 2.5.3, and
(ii) on the date that is three (3) Business Days prior to each Put Date (the
"Registration Opinion Deadline"), an opinion of the Company's independent
counsel, in substantially the form of Exhibit R (the "Registration Opinion"),
addressed to the Investor stating, inter alia, that no facts ("Material Facts")
have come to such counsel's attention that have caused it to believe that the
Registration Statement is subject to an Ineffective Period or to believe that
the Registration Statement, any Supplemental Registration Statement (as each may
be amended, if applicable), and any related prospectuses, contain an untrue
statement of material fact or omits a material fact required to make the
statements contained therein, in light of the circumstances under which they
were made, not misleading. If a Registration Opinion cannot be delivered by the
Company's independent counsel to the Investor on the Registration Opinion
Deadline due to the existence of Material Facts or an Ineffective Period, the
Company shall promptly notify the Investor and as promptly as possible amend
each of the Registration Statement and any Supplemental Registration Statements,
as applicable, and any related prospectus or cause such Ineffective Period to
terminate, as the case may be, and deliver such Registration Opinion and updated
prospectus as soon as possible thereafter. If at any time after a Put Notice
shall have been delivered to Investor but before the related Pricing Period End
Date, the Company acquires knowledge of such Material Facts or any Ineffective
Period occurs, the Company shall promptly notify the Investor and shall deliver
a Put Cancellation Notice to the Investor pursuant to Section 2.3.11 by
facsimile and overnight courier by the end of that Business Day.

               (b) (i) the Company shall engage its independent auditors to
perform the procedures in accordance with the provisions of Statement on
Auditing Standards No. 71, as amended, as agreed to by the parties hereto, and
reports thereon (the "Bring Down Cold Comfort Letters") as shall have been
reasonably requested by the Investor with respect to certain financial
information contained in the Registration Statement and shall have delivered to
the Investor such a report addressed to the Investor, on the date that is three
(3) Business Days prior to each Put Date.

                    (ii) in the event that the Investor shall have requested
delivery of an Agreed Upon Procedures Report pursuant to Section 2.5.3, the
Company shall engage its independent auditors to perform certain agreed upon
procedures and report thereon as shall have been reasonably requested by the
Investor with respect to certain financial information of the Company and the
Company shall deliver to the Investor a copy of such report addressed to the
Investor. In the event that the Agreed Upon Procedures Report cannot be
delivered by the Company's independent auditors, the Company shall, if
necessary, promptly revise the Registration Statement and the Company shall not
deliver a Put Notice until such report is delivered.

          2.3.7 Investor's Obligation and Right to Purchase Shares. Subject to
the conditions set forth in this Agreement, following the Investor's receipt of
a validly delivered Put Notice, the Investor shall be required to purchase (each
a "Purchase") from the Company a number of Put Shares equal to the Put Share
Amount, in the manner described below.

          2.3.8 Mechanics of Put Closing. Each of the Company and the Investor
shall deliver all documents, instruments and writings required to be delivered
by either of them pursuant to this Agreement at or prior to each Closing.
Subject to such delivery and the satisfaction of the conditions set forth in
Sections 2.3.4 and 2.3.5, the closing of the purchase by the Investor of Put
Shares shall occur by 5:00 PM, New York City Time, on the date which is five (5)
Business Days following the applicable Pricing Period End Date (or such other
time or later date as is mutually agreed to by the Company and the Investor)
(the "Payment Due Date") at the offices of Investor. On each or before each
Payment Due Date, the Investor shall deliver to the Company, in the manner

<PAGE>

specified in Section 8 below, the Put Dollar Amount to be paid for such Put
Shares, determined as aforesaid. The closing (each a "Put Closing") for each Put
shall occur on the date that both (i) the Company has delivered to the Investor
all Required Put Documents, and (ii) the Investor has delivered to the Company
such Put Dollar Amount and any Late Payment Amount, if applicable (each a "Put
Closing Date").

     If the Investor does not deliver to the Company the Put Dollar Amount for
such Put Closing on or before the Payment Due Date, then the Investor shall pay
to the Company, in addition to the Put Dollar Amount, an amount (the "Late
Payment Amount") at a rate of X% per month, accruing daily, multiplied by such
Put Dollar Amount, where "X" equals one percent (1%) for the first month
following the date in question, and increases by an additional one percent (1%)
for each month that passes after the date in question, up to a maximum of five
percent (5%) per month; provided, however, that in no event shall the amount of
interest that shall become due and payable hereunder exceed the maximum amount
permissible under applicable law.

          2.3.9 Limitation on Short Sales. The Investor and its Affiliates shall
not engage in short sales of the Company's Common Stock; provided, however, that
the Investor may enter into any short exempt sale or any short sale or other
hedging or similar arrangement it deems appropriate with respect to Put Shares
after it receives a Put Notice with respect to such Put Shares so long as such
sales or arrangements do not involve more than the number of such Put Shares
specified in the Put Notice.

          2.3.10 Cap Amount. If the Company becomes listed on the Nasdaq Small
Cap Market or the Nasdaq National Market, then, unless the Company has obtained
Stockholder 20% Approval as set forth in Section 6.11 or unless otherwise
permitted by Nasdaq, in no event shall the Aggregate Issued Shares exceed the
maximum number of shares of Common Stock (the "Cap Amount") that the Company
can, without stockholder approval, so issue pursuant to Nasdaq Rule
4460(i)(1)(d)(ii) (or any other applicable Nasdaq Rules or any successor rule)
(the "Nasdaq 20% Rule").

          2.3.11 Put Cancellation.

               (a) Mechanics of Put Cancellation. If at any time during a
Pricing Period the Company discovers the existence of Material Facts or any
Ineffective Period or Delisting Event occurs, the Company shall cancel the Put
(a "Put Cancellation"), by delivering written notice to the Investor (the "Put
Cancellation Notice"), attached as Exhibit Q, by facsimile and overnight
courier. The "Put Cancellation Date" shall be the date that the Put Cancellation
Notice is first received by the Investor, if such notice is received by the
Investor by 6:00 p.m., New York, NY time, and shall be the following date, if
such notice is received by the Investor after 6:00 p.m., New York, NY time.

               (b) Effect of Put Cancellation. Anytime a Put Cancellation Notice
is delivered to Investor after the Put Date, the Put, shall remain effective
with respect to a number of Put Shares (the "Truncated Put Share Amount") equal

               (c) Put Cancellation Notice Confirmation. Upon receipt by the

Cancellation Notice to the Company specifying that the Put Cancellation Notice
has been received and affirming the Put Cancellation Date.

               (d) Truncated Pricing Period. If a Put Cancellation Notice has
been delivered to the Investor after the Put Date, the Pricing Period for such

"Company Termination") its right to initiate future Puts by providing written
notice ("Termination Notice") to the Investor, by facsimile and overnight
courier, at any time other than during an Extended Put Period, provided that

obligations under this Agreement, the Registration Rights Agreement or the
Warrants. Notwithstanding the above, any cancellation occurring during an
Extended Put Period is governed by Section 2.3.11.

<PAGE>

          2.3.13 Return of Excess Common Shares. In the event that the number of

shall be exercisable at a price (the "Commitment Warrant Exercise Price") which
shall initially equal the lowest Closing Bid Price for the five (5) Business
Days immediately preceding January 10, 2000 ("Initial Exercise Price"), or, if

preceding the date of execution by the Company of this Investment Agreement, and
shall have reset provisions. Each Commitment Warrant shall have a term beginning
on the date of issuance and ending on date that is five (5) years thereafter.
The Warrant Shares shall be registered for resale pursuant to the Registration
Rights Agreement. The Investment Commitment Opinion of Counsel shall cover the
issuance of the Commitment Warrant and the issuance of the common stock upon
exercise of the Commitment Warrant.

     Notwithstanding any Termination or Automatic Termination of this Agreement,
the Investor shall retain full ownership of the Commitment Warrant as partial
consideration for its commitment hereunder.

               2.4.2 Purchase Warrants. Within five (5) Business Days of the end
of each Pricing Period, the Company shall issue and deliver to the Investor a
warrant ("Purchase Warrant"), in the form attached hereto as Exhibit D, or such
other form as agreed upon by the parties, to purchase a number of shares of
Common Stock equal to 15% of the Put Share Amount for that Put. Each Purchase
Warrant shall be exercisable at a price (the "Purchase Warrant Exercise Price")
which shall initially equal 110% of the Market Price for the applicable Put, and
shall have semi-annual reset provisions. Each Purchase Warrant shall be
immediately exercisable at the Purchase Warrant Exercise Price, and shall have a
term beginning on the date of issuance and ending on the date that is five (5)
years thereafter. The Warrant Shares shall be registered for resale pursuant to
the Registration Rights Agreement.

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

          2.5.1 Treatment of Nonpublic Information. The Company shall not
disclose nonpublic information to the Investor or to its advisors or
representatives unless prior to disclosure of such information the Company
identifies such information as being nonpublic information and provides the
Investor and such advisors and representatives with the opportunity to accept or
refuse to accept such nonpublic information for review. The Company may, as a

<PAGE>

condition to disclosing any nonpublic information hereunder, require the
Investor and its advisors and representatives to enter into a confidentiality
agreement (including an agreement with such advisors and representatives
prohibiting them from trading in Common Stock during such period of time as they
are in possession of nonpublic information) in form reasonably satisfactory to
the Company and the Investor.

     Nothing herein shall require the Company to disclose nonpublic information
to the Investor or its advisors or representatives, and the Company represents
that it does not disseminate nonpublic information to any investors who purchase
stock in the Company in a public offering, to money managers or to securities
analysts, provided, however, that notwithstanding anything herein to the
contrary, the Company will, as hereinabove provided, immediately notify the
advisors and representatives of the Investor and, if any, underwriters, of any
event or the existence of any circumstance (without any obligation to disclose
the specific event or circumstance) of which it becomes aware, constituting
nonpublic information (whether or not requested of the Company specifically or
generally during the course of due diligence by and such persons or entities),
which, if not disclosed in the Prospectus included in the Registration
Statement, would cause such Prospectus to include a material misstatement or to
omit a material fact required to be stated therein in order to make the
statements therein, in light of the circumstances in which they were made, not
misleading. Nothing contained in this Section 2.5.1 shall be construed to mean
that such persons or entities other than the Investor (without the written
consent of the Investor prior to disclosure of such information) may not obtain
nonpublic information in the course of conducting due diligence in accordance
with the terms of this Agreement; provided, however, that in no event shall the
Investor's advisors or representatives disclose to the Investor the nature of
the specific event or circumstances constituting any nonpublic information
discovered by such advisors or representatives in the course of their due
diligence without the written consent of the Investor prior to disclosure of
such information.

               2.5.2 Disclosure of Misstatements and Omissions. The Investor's
advisors or representatives shall make complete disclosure to the Investor's
counsel of all events or circumstances constituting nonpublic information
discovered by such advisors or representatives in the course of their due
diligence upon which such advisors or representatives form the opinion that the
Registration Statement contains an untrue statement of a material fact or omits
a material fact required to be stated in the Registration Statement or necessary
to make the statements contained therein, in the light of the circumstances in
which they were made, not misleading. Upon receipt of such disclosure, the
Investor's counsel shall consult with the Company's independent counsel in order
to address the concern raised as to the existence of a material misstatement or
omission and to discuss appropriate disclosure with respect thereto; provided,
however, that such consultation shall not constitute the advice of the Company's
independent counsel to the Investor as to the accuracy of the Registration
Statement and related Prospectus.

               2.5.3 Procedure if Material Facts are Reasonably Believed to be
Untrue or are Omitted. In the event after such consultation the Investor or the
Investor's counsel reasonably believes that the Registration Statement contains
an untrue statement or a material fact or omits a material fact required to be
stated in the Registration Statement or necessary to make the statements
contained therein, in light of the circumstances in which they were made, not
misleading,

                    (a) the Company shall file with the SEC an amendment to the
Registration Statement responsive to such alleged untrue statement or omission
and provide the Investor, as promptly as practicable, with copies of the
Registration Statement and related Prospectus, as so amended, or

                    (b) if the Company disputes the existence of any such
material misstatement or omission, (i) the Company's independent counsel shall
provide the Investor's counsel with a Registration Opinion and (ii) in the event
the dispute relates to the adequacy of financial disclosure and the Investor
shall reasonably request, the Company's independent auditors shall provide to
the Company a letter ("Agreed Upon Procedures Report") outlining the performance
of such "agreed upon procedures" as shall be reasonably requested by the
Investor and the Company shall provide the Investor with a copy of such letter.

          2.6 Commitment Payments.
              -------------------

               2.6.1 Non-Usage Fees and Termination Fee. On the last Business
Day of each six (6) Calendar Month period following the Effective Date (each
such period a "Commitment Evaluation Period"), if the Company has not Put the
lesser of (i) $1,000,000 in aggregate Put Dollar Amount or (ii) the Put Dollar
Amount for the Volume Limitation during that Commitment Evaluation Period, then
the Company, in consideration of Investor's commitment costs, including, but not

<PAGE>

limited to, due diligence expenses, shall pay to the Investor an amount (the
"Semi-Annual Non-Usage Fee ") equal to the difference of (i) $100,000, minus
(ii) 10% of the aggregate Put Dollar Amount of the Put Shares put to Investor
during that Commitment Evaluation Period. In the event that the Company delivers
a Termination Notice to the Investor or an Automatic Termination occurs, the
Company shall pay to the Investor (the "Termination Fee") the greater of (i) the
Semi-Annual Non-Usage Fee for the applicable Commitment Evaluation Period, or
(ii) the difference of (x) $200,000, minus (y) 10% of the aggregate Put Dollar
Amount of the Put Shares put to Investor during all Puts to date, and the
Company shall not be required to pay the Semi-Annual Non-Usage Fee thereafter.

     Notwithstanding anything in this Agreement to the contrary, the Investor
shall not be entitled to receive the Termination Fee contemplated by this
Section 2.6.1 as a result of any Automatic Termination pursuant to Sections
2.3.2 (d), (f) or (g) above, assuming that, in the case of an Automatic
Termination pursuant to Section 2.3.2 (f) above, both of the following have
occurred: (i) the Company has filed the Registration Statement by the Filing
Deadline (as defined in the Registration Rights Agreement), and (ii) the Company
has used its reasonable best efforts to have the Registration Statement declared
effective and has responded to any comments from the Securities and Exchange
Commission within 30 days of receipt thereof.

     Each Semi Annual Non-Usage Fee or Termination Fee is payable, in cash,
within five (5) Business Days of the date it accrued. No additional Non-Usage
Fees shall accrue after (i) a Company Termination, (ii) an Automatic
Termination, or (iii) a termination of this Agreement under the terms of Section
6.13, provided that any Non-Usage Fees which have accrued prior to the
occurrence of (i), (ii), or (iii) above shall be payable within five (5)
business days of such occurrence. The Company shall not be required to deliver
any payments to Investor under this subsection until Investor has paid all Put
Dollar Amounts that are then due. If the Investor, at any time, is more than
five (5) Business Days late in paying any Put Dollar Amounts that are then due,
the Investor shall not be entitled to the benefits of this Section 2.6.1 until
fifteen (15) Business Days after the date that the Investor pays all Put Dollar
Amounts that are then due.

               2.6.2 Suspension Without Accruing Non-Usage Fees. Notwithstanding
the above, beginning on the Effective Date, the Company shall be entitled to
suspend this Offering (each a "Suspension") for up to six (6) periods not to
exceed an aggregate of nine (9) Calendar Months for the purpose of effecting one
or more secondary underwritten offerings or for the purpose of Ineffective
Periods, by giving written notice to the Investor stating the beginning date and
the duration of such Suspension. During the term of such Suspension, the Company
may not deliver any Advance Put Notices or effect any Puts.

     The Non-Usage Fees for any Commitment Evaluation Period(s) which occur
during a Suspension will be reduced by 1/6 for each full Calendar Month (or pro
rata for each partial Calendar Month) of the Suspension.

investment pursuant to this Agreement and that Investor is an "Accredited
Investor" by virtue of the fact that Investor meets the investor qualification

               3.3.1 No General Solicitation. The Investment Agreement was not

applicable regulations such securities may not be transferred or resold without
registration under the Act or pursuant to an exemption therefrom. In this
connection, Investor represents that Investor is familiar with Rule 144 under

thereby and by the Act.

<PAGE>


               3.3.3 Disposition. Without in any way limiting the

transferred to or assigned to any broker, dealer or depositary. Investor further
agrees not to sell, transfer, assign, or pledge the Securities (except for any
bona fide pledge arrangement to the extent that such pledge does not require
registration under the Act or unless an exemption from such registration is
available and provided further that if such pledge is realized upon, any
transfer to the pledgee shall comply with the requirements set forth herein), or
to otherwise dispose of all or any portion of the Securities unless and until:

the Act and any applicable state securities laws covering such proposed
disposition and such disposition is made in accordance with such registration
statement and in compliance with applicable prospectus delivery requirements; or

proposed disposition and shall have furnished the Company with a statement of
the circumstances surrounding the proposed disposition to the extent relevant
for determination of the availability of an exemption from registration, and
(ii) if reasonably requested by the Company, Investor shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of the Securities under the Act
or state securities laws. It is agreed that the Company will not require the
Investor to provide opinions of counsel for transactions made pursuant to Rule
144 provided that Investor and Investor's broker, if necessary, provide the
Company with the necessary representations for counsel to the Company to issue
an opinion with respect to such transaction.

          The Investor is entering into this Agreement for its own account and
the Investor has no present arrangement (whether or not legally binding) at any
time to sell the Common Stock to or through any person or entity; provided,
however, that by making the representations herein, the Investor does not agree
to hold the Common Stock for any minimum or other specific term and reserves the

Company has obtained all consents and approvals required for it to execute,
deliver and perform each agreement referenced in the previous sentence.

          5.4 Valid Issuance of Common Stock. The Common Stock and the Warrants,
when issued, sold and delivered in accordance with the terms hereof, for the
consideration expressed herein, will be validly issued, fully paid and
nonassessable and, based in part upon the representations of Investor in this
Agreement, will be issued in compliance with all applicable U.S. federal and
state securities laws. The Warrant Shares, when issued in accordance with the
terms of the Warrants, shall be duly and validly issued and outstanding, fully

form as agreed upon by the parties.

          6.8 Removal of Legend. If the certificates representing any Securities
are issued with a restrictive Legend in accordance with the terms of this
Agreement, the Legend shall be removed and the Company shall issue a certificate
without such Legend to the holder of any Security upon which it is stamped, and
a certificate for a security shall be originally issued without the Legend, if
(a) the sale of such Security is registered under the Act, or (b) such holder
provides the Company with an opinion of counsel, in form, substance and scope

<PAGE>

cost of which shall be borne by the Investor), to the effect that a public sale
or transfer of such Security may be made without registration under the Act, or
(c) such holder provides the Company with reasonable assurances that such
Security can be sold pursuant to Rule 144. Each Investor agrees to sell all
Securities, including those represented by a certificate(s) from which the
Legend has been removed, or which were originally issued without the Legend,
pursuant to an effective registration statement and to deliver a prospectus in
connection with such sale or in compliance with an exemption from the
registration requirements of the Act.

          6.9 Listing. Subject to the remainder of this Section 6.9, the Company
shall ensure that its shares of Common Stock (including all Warrant Shares and
Put Shares) are listed and available for trading on the O.T.C. Bulletin Board.
Thereafter, the Company shall (i) use its best efforts to continue the listing
and trading of its Common Stock on the O.T.C. Bulletin Board or to become
eligible for and listed and available for trading on the Nasdaq Small Cap
Market, the Nasdaq National Market, or the New York Stock Exchange ("NYSE"); and

instruct the Transfer Agent of the Common Stock, by delivering instructions in
the form of Exhibit T hereto, to issue certificates, registered in the name of
each Investor or its nominee, for the Put Shares and Warrant Shares in such
amounts as specified from time to time by the Company upon any exercise by the
Company of a Put and/or exercise of the Warrants by the holder thereof. Such
certificates shall not bear a Legend unless issuance with a Legend is permitted
by the terms of this Agreement and Legend removal is not permitted by Section
6.8 hereof and the Company shall cause the Transfer Agent to issue such
certificates without a Legend. Nothing in this Section shall affect in any way
Investor's obligations and agreement set forth in Sections 3.3.2 or 3.3.3 hereof
to resell the Securities pursuant to an effective registration statement and to
deliver a prospectus in connection with such sale or in compliance with an
exemption from the registration requirements of applicable securities laws. If
(a) an Investor provides the Company with an opinion of counsel, which opinion
of counsel shall be in form, substance and scope customary for opinions of
counsel in comparable transactions, to the effect that the Securities to be sold
or transferred may be sold or transferred pursuant to an exemption from
registration or (b) an Investor transfers Securities, pursuant to Rule 144, to a
transferee which is an Accredited Investor, the Company shall permit the
transfer, and, in the case of Put Shares and Warrant Shares, promptly instruct
its transfer agent to issue one or more certificates in such name and in such
denomination as specified by such Investor. The Company acknowledges that a
breach by it of its obligations hereunder will cause irreparable harm to an
Investor by vitiating the intent and purpose of the transaction contemplated
hereby. Accordingly, the Company acknowledges that the remedy at law for a
breach of its obligations under this Section 6.10 will be inadequate and agrees,
in the event of a breach or threatened breach by the Company of the provisions
of this Section 6.10, that an Investor shall be entitled, in addition to all
other available remedies, to an injunction restraining any breach and requiring
immediate issuance and transfer, without the necessity of showing economic loss
and without any bond or other security being required.

          6.11 Stockholder 20% Approval. Prior to the closing of any Put that
would cause the Aggregate Issued Shares to exceed the Cap Amount, if required by
the rules of NASDAQ because the Company's Common Stock is listed on NASDAQ, the
Company shall obtain approval of its stockholders to authorize (i) the issuance
of the full number of shares of Common Stock which would be issuable pursuant to
this Agreement but for the Cap Amount and eliminate any prohibitions under
applicable law or the rules or regulations of any stock exchange, interdealer
quotation system or other self-regulatory organization with jurisdiction over
the Company or any of its securities with respect to the Company's ability to
issue shares of Common Stock in excess of the Cap Amount (such approvals being
the "Stockholder 20% Approval").

          6.12 Press Release. The Company agrees that the Investor shall have
the right to review and comment upon any press release issued by the Company in
connection with the Offering which approval shall not be unreasonably withheld
by Investor.

          6.13 Change in Law or Policy. In the event of a change in law, or
policy of the SEC, as evidenced by a No-Action letter or other written
statements of the SEC or the NASD which causes the Investor to be unable to
perform its obligations hereunder, this Agreement shall be automatically
terminated and no Termination Fee shall be due, provided that notwithstanding
any termination under this section 6.13, the Investor shall retain full
ownership of the Commitment Warrant as partial consideration for its commitment
hereunder.

the action for which indemnification hereunder is sought), and including
reasonable attorne s fees and disbursements (the "Indemnified Liabilities"),
incurred by any Indemnitee, in an action by a party other than the Company, as a
result of, or arising out of, or relating to (a) any misrepresentation or breach
of any representation or warranty made by the Company in the Transaction
Documents or any other certificate, instrument or documents contemplated hereby
or thereby, (b) any breach of any covenant, agreement or obligation of the
Company contained in the Transaction Documents or any other certificate,
instrument or document contemplated hereby or thereby, (c) any cause of action,
suit or claim, derivative or otherwise, by any stockholder of the Company based
on a breach or alleged breach by the Company or any of its officers or directors
of their fiduciary or other obligations to the stockholders of the Company, or
(d) claims made by third parties against any of the Indemnitees based on a
violation of Section 5 of the Securities Act caused by the integration of the
private sale of common stock to the Investor and the public offering pursuant to
the Registration Statement.

     To the extent that the foregoing undertaking by the Company may be
unenforceable for any reason, the Company shall make the maximum contribution to
the payment and satisfaction of each of the Indemnified Liabilities which it
would be required to make if such foregoing undertaking was enforceable which is
permissible under applicable law.

     Promptly after receipt by an Indemnified Party of notice of the
commencement of any action pursuant to which indemnification may be sought, such
Indemnified Party will, if a claim in respect thereof is to be made against the
other party (hereinafter "Indemnitor") under this Section 9, deliver to the
Indemnitor a written notice of the commencement thereof and the Indemnitor shall
have the right to participate in and to assume the defense thereof with counsel
reasonably selected by the Indemnitor, provided, however, that an Indemnified
Party shall have the right to retain its own counsel, with the reasonably
incurred fees and expenses of such counsel to be paid by the Indemnitor, if
representation of such Indemnified Party by the counsel retained by the
Indemnitor would be inappropriate due to actual or potential conflicts of
interest between such Indemnified Party and any other party represented by such

counsel in such proceeding. The failure to deliver written notice to the
Indemnitor within a reasonable time of the commencement of any such action, if
prejudicial to the Indemnitor's ability to defend such action, shall relieve the
Indemnitor of any liability to the Indemnified Party under this Section 9, but
the omission to so deliver written notice to the Indemnitor will not relieve it
of any liability that it may have to any Indemnified Party other than under this
Section 9 to the extent it is prejudicial.

Warrant to Purchase
250,000 shares
- --------------

                        Warrant to Purchase Common Stock
                                       of
                              U.S. MICROBICS, INC.

     THIS CERTIFIES that Swartz Private Equity, LLC, or any subsequent holder
hereof pursuant to Section 8 hereof ("Holder"), has the right to purchase from,
U.S. Microbics, Inc., a Colorado corporation (the "Company"), up to 250,000
fully paid and nonassessable shares of the Company's common stock, $.0001 par
value per share ("Common Stock"), subject to adjustment as provided herein, at a
price equal to the Exercise Price as defined in Section 3 below, at any time
beginning on the Date of Issuance (defined below) and ending at 5:00 p.m., New
York, New York time the date that is five (5) years after the Date of Issuance
(the "Exercise Period").

     Holder agrees with the Company that this Warrant to purchase shares of
Common Stock of the Company (this "Warrant") is issued and all rights hereunder
shall be held subject to all of the conditions, limitations and provisions set
forth herein.

     1. Date of Issuance and Term.
        --------------------------

     This Warrant shall be deemed to be issued on January 27, 2000 ("Date of
Issuance"). The term of this Warrant is five (5) years from the Date of
Issuance.

     This Warrant is exercisable into shares of Common Stock (the "Warrant
Shares") as follows: (i) one hundred thousand (100,000) of the Warrant Shares
after the ten (10) business day document review period (the "Review Period")
referenced in the Equity Line Letter of Agreement dated on or about January 10,
2000, between Holder and the Company (the "Letter of Agreement") has ended; (ii)
an additional seventy-five thousand (75,000) of the Warrant Shares upon the
execution of all Closing Documents (as defined in the Letter of Agreement); and
(iii) the remaining seventy-five thousand (75,000) Warrant Shares upon the
sooner of (a) the date that is 6 months from the date of the Letter of Agreement
or (b) the date of effectiveness of the Company's registration statement (the
"Registration Statement") to be filed pursuant to the Closing Documents.

     Anything in this Warrant to the contrary notwithstanding, if the Company
delivers written notice to Holder prior to the expiration of the Review Period
that the Closing Documents are unacceptable and the Company wishes to terminate
the transaction, then Holder shall return this Warrant to the Company and all of
Holder's rights under this Warrant shall be null and void and of no effect.

     2. Exercise.
        --------

     (a) Manner of Exercise. Subject to the provisions of Section 1, during the
Exercise Period, this Warrant may be exercised as to all or any lesser number of
Warrant Shares upon surrender of this Warrant, with the Exercise Form for

<PAGE>

Warrant attached hereto as Exhibit A (the "Exercise Form") duly completed and
executed, together with the full Exercise Price (as defined below) for each
share of Common Stock as to which this Warrant is exercised, at the office of
the Company, Attention: Robert C. Brehm, CEO, 5922-B Farnsworth Court, Carlsbad,
CA 92008, Telephone (760) 918-1860, ext.102, Facsimile (760) 918-1855, or at
such other office or agency as the Company may designate in writing, by
overnight mail, with an advance copy of the Exercise Form sent to the Company
and its Transfer Agent by facsimile (such surrender and payment of the Exercise
Price hereinafter called the "Exercise of this Warrant").

     (b) Date of Exercise. The "Date of Exercise" of this Warrant shall be
defined as the date that the advance copy of the completed and executed Exercise
Form is sent by facsimile to the Company, provided that the original Warrant and
Exercise Form are received by the Company as soon as practicable thereafter.
Alternatively, the Date of Exercise shall be defined as the date the original
Exercise Form is received by the Company, if Holder has not sent advance notice
by facsimile.

     (c) Cancellation of Warrant. This Warrant shall be canceled upon the
exercise of this Warrant, and, as soon as practicable after the Date of
Exercise, Holder shall be entitled to receive Common Stock for the number of
shares purchased upon such exercise of this Warrant, and if this Warrant is not
exercised in full, then Holder shall be entitled to receive a new Warrant
(containing terms identical to this Warrant) representing any unexercised
portion of the Warrant Shares.

     (d) Holder of Record. Each person in whose name any Warrant Shares are
issued shall, for all purposes, be deemed to be the Holder of record of such
shares on the Date of exercise of this Warrant, irrespective of the date of
delivery of the Warrant Shares purchased upon the exercise of this Warrant.
Nothing in this Warrant shall be construed as conferring upon Holder any rights
as a shareholder of the Company.


     3. Payment of Warrant Exercise Price.
        ---------------------------------

     The Exercise Price per share ("Exercise Price") shall initially equal (the
"Initial Exercise Price") the lowest Closing Bid Price for the five (5) trading
days immediately preceding January 10, 2000. If the lowest Closing Bid Price of
the Company's Common Stock for the five (5) trading days immediately preceding
the date, if any, that the Company and Swartz Private Equity, LLC enter into an
Investment Agreement ("Investment Agreement") pursuant to the Letter of
Agreement (the "Closing Market Price") is less than the Initial Exercise Price,
the Exercise Price shall be reset to equal the Closing Market Price, or, if the
Date of Exercise is more than six (6) months after the Date of Issuance, the
Exercise Price shall be reset to equal the lesser of (i) the Exercise Price then
in effect, or (ii) the "Lowest Reset Price," as that term is defined below. The
Company shall calculate a "Reset Price" on each six-month anniversary date of
the Date of Issuance, up through the date that is three (3) years from the Date
of Issuance, which shall equal one hundred percent (100%) of the average Closing
Bid Price of the Company's Common Stock for the five (5) trading days ending on
such six-month anniversary date of the Date of Issuance. The "Lowest Reset
Price" shall equal the lowest Reset Price determined on any six-month
anniversary date of the Date of Issuance preceding the Date of Exercise, taking
into account, as appropriate, any adjustments made pursuant to Section 5 hereof.

     Payment of the Exercise Price may be made by either of the following, or a
combination thereof, at the election of Holder:

     (i) "Cash Exercise:" cash, bank or cashiers check or wire transfer; or

     (ii) "Cashless Exercise:" The Holder, at its option, may exercise this
Warrant in a cashless exercise transaction under this subsection (ii) if and
only if, on the Date of Exercise, there is not then in effect a current
registration statement that covers the resale of the Warrant Shares to be issued
upon exercise of this Warrant. In order to effect a cashless exercise, the
Holder shall surrender this Warrant at the principal office of the Company
together with notice of cashless election, in which event the Company shall
issue Holder a number of shares of Common Stock computed using the following
formula:

<PAGE>


                                  X = Y (A-B)/A

where: X = the number of shares of Common Stock to be issued to Holder.

       Y = the number of shares of Common Stock for which this Warrant is being
           exercised.

               A = the Market Price of one (1) share of Common Stock (for
               purposes of this Section 3(ii), the "Market Price" shall be
               defined as the average closing price of the Common Stock for the
               five (5) trading days prior to the Date of Exercise of this
               Warrant (the "Average Closing Price"), as reported by the
               Over-The-Counter Bulletin Board ("OTC Bulletin Board"), National
               Association of Securities Dealers Automated Quotation System
               ("Nasdaq") SmallCap Market, or if the Common Stock is not traded
               on the Nasdaq SmallCap Market, the Average Closing Price in any
               other over-the-counter market; provided, however, that if the
               Common Stock is listed on a stock exchange, the Market Price
               shall be the Average Closing Price on such exchange for the five
               (5) trading days prior to the Date of Exercise of this Warrant.
               If the Common Stock is/was not traded during the five (5) trading
               days prior to the Date of Exercise, then the closing price for
               the last publicly traded day shall be deemed to be the closing
               price for any and all (if applicable) days during such five (5)
               trading day period.

               B = the Exercise Price.

     For purposes hereof, the term "Closing Bid Price" shall mean the closing
bid price on the Nasdaq SmallCap Market, the National Market System ("NMS"), the
New York Stock Exchange, or the OTC Bulletin Board, or if no longer traded on
the Nasdaq SmallCap Market, the NMS, the New York Stock Exchange, or the OTC
Bulletin Board, the "Closing Bid Price" shall equal the closing price on the
principal national securities exchange or the over-the-counter system on which
the Common Stock is so traded and, if not available, the mean of the high and
low prices on the principal national securities exchange on which the Common
Stock is so traded.

     For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is
intended, understood and acknowledged that the Warrant Shares issuable upon
exercise of this Warrant in a cashless exercise transaction shall be deemed to
have been acquired at the time this Warrant was issued. Moreover, it is
intended, understood and acknowledged that the holding period for Warrant Shares
issuable upon exercise of this Warrant in a cashless exercise transaction shall
be deemed to have commenced on the date this Warrant was issued.

     4. Transfer and Registration.
        -------------------------

     (a) Transfer Rights. Subject to the provisions of Section 8 of this
Warrant, this Warrant may be transferred on the books of the Company, in whole
or in part, in person or by attorney, upon surrender of this Warrant properly
completed and endorsed. This Warrant shall be canceled upon such surrender and,
as soon as practicable thereafter, the person to whom such transfer is made
shall be entitled to receive a new warrant or warrants as to the portion of the
Warrant Shares transferred, and Holder shall be entitled to receive a new
warrant as to the portion hereof retained.

     (b) Registrable Securities. In addition to any other registration rights of
the Holder, if the Warrant Shares issuable upon exercise of this Warrant is not
registered for resale at the time the Company proposes to register (including
for this purpose a registration effected by the Company for shareholders other
than Holder) any of its Common Stock under the Securities Act (other than a
registration relating solely for the sale of securities to participants in the
Company's stock plan or a registration on Form S-4 promulgated under the
Securities Act or any successor or similar form registering stock issuable upon
a reclassification, upon a business combination involving an exchange of
securities or upon an exchange offer for securities of the issuer or another
entity) (a "Piggyback Registration Statement"), the Company shall cause to be
included in such Piggyback Registration Statement ("Piggyback Registration") all
of the Warrant Shares issuable upon the exercise of this Warrant ("Registrable
Securities") to the extent such inclusion does not violate the registration
rights of any other shareholder of the Company granted prior to the date hereof.
Nothing herein shall prevent the Company from withdrawing or abandoning the
Piggyback Registration Statement prior to its effectiveness.

<PAGE>


     (c) Limitation on Obligations to Register under a Piggyback Registration.
In the case of a Piggyback Registration pursuant to an underwritten public
offering by the Company, if the managing underwriter determines and advises in
writing that the inclusion in the registration statement of all Registrable
Securities proposed to be included would interfere with the successful marketing
of the securities proposed to be registered by the Company, then the number of
such Registrable Securities to be included in the Piggyback Registration
Statement, to the extent such Registrable Securities may be included in such
Piggyback Registration Statement, shall be allocated among all Holders who had
requested Piggyback Registration pursuant to the terms hereof, in the proportion
that the number of Registrable Securities which each such Holder seeks to
register bears to the total number of Registrable Securities sought to be
included by all Holders. If required by the managing underwriter of such an
underwritten public offering, the Holders shall enter into a reasonable
agreement limiting the number of Registrable Securities to be included in such
Piggyback Registration Statement and the terms, if any, regarding the future
sale of such Registrable Securities.




<PAGE>

     5. Anti-Dilution Adjustments.
        -------------------------

     (a) Stock Dividend. If the Company shall at any time declare a dividend
payable in shares of Common Stock, then Holder, upon exercise of this Warrant
after the record date for the determination of holders of Common Stock entitled
to receive such dividend, shall be entitled to receive upon exercise of this
Warrant, in addition to the number of Warrant Shares as to which this Warrant is
exercised, such additional shares of Common Stock as such Holder would have
received had this Warrant been exercised immediately prior to such record date
and the Exercise Price will be proportionately adjusted.

     (b) Recapitalization or Reclassification.

          (i) Stock Split. If the Company shall at any time effect a
recapitalization, reclassification or other similar transaction of such
character that the Warrant Shares shall be changed into or become exchangeable
for a larger number of shares (a "Stock Split"), then upon the effective date
thereof, the number of shares of Common Stock which Holder shall be entitled to
purchase upon exercise of this Warrant shall be increased in direct proportion
to the increase in the number of shares of Common Stock by reason of such
recapitalization, reclassification or similar transaction, and the Exercise
Price shall be proportionally decreased.

          (ii) Reverse Stock Split. If the Company shall at any time effect a
recapitalization, reclassification or other similar transaction of such
character that the Warrant Shares shall be changed into or become exchangeable
for a smaller number of shares (a "Reverse Stock Split"), then upon the
effective date thereof, the number of shares of Common Stock which Holder shall
be entitled to purchase upon exercise of this Warrant shall be proportionately
decreased and the Exercise Price shall be proportionally increased. The Company
shall give Holder the same notice it provides to holders of Common Stock of any
transaction described in this Section 5(b).

     (c) Distributions. If the Company shall at any time distribute for no
consideration to holders of Common Stock cash, evidences of indebtedness or
other securities or assets (other than cash dividends or distributions payable
out of earned surplus or net profits for the current or preceding years) then,
in any such case, Holder shall be entitled to receive, upon exercise of this
Warrant, with respect to each of the Warrant Shares issuable upon such exercise,
the amount of cash or evidences of indebtedness or other securities or assets
which Holder would have been entitled to receive with respect to each such share
of Common Stock as a result of the happening of such event had this Warrant been
exercised immediately prior to the record date or other date fixing shareholders
to be affected by such event (the "Determination Date") or, in lieu thereof, if
the Board of Directors of the Company should so determine at the time of such
distribution, a reduced Exercise Price determined by multiplying the Exercise
Price on the Determination Date by a fraction, the numerator of which is the
result of such Exercise Price reduced by the value of such distribution
applicable to one share of Common Stock (such value to be determined by the
Board of Directors of the Company in its discretion) and the denominator of
which is such Exercise Price.

     (d) Notice of Consolidation or Merger. In the event of a merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event, as a result of which shares of Common Stock shall be changed into
the same or a different number of shares of the same or another class or classes
of stock or securities or other assets of the Company or another entity or there
is a sale of all or substantially all the Company's assets (a "Corporate
Change"), then this Warrant shall be exercisable into such class and type of
securities or other assets as Holder would have received had Holder exercised
this Warrant immediately prior to such Corporate Change; provided, however, that
Company may not affect any Corporate Change unless it first shall have given
thirty (30) days notice to Holder hereof of any Corporate Change.

     (e) Exercise Price Adjusted. As used in this Warrant, the term "Exercise
Price" shall mean the purchase price per share specified in Section 3 of this
Warrant, until the occurrence of an event stated in subsection (a), (b) or (c)
of this Section 5, and thereafter shall mean said price as adjusted from time to
time in accordance with the provisions of said subsection. No such adjustment
under this Section 5 shall be made unless such adjustment would change the
Exercise Price at the time by $.01 or more; provided, however, that all
adjustments not so made shall be deferred and made when the aggregate thereof
would change the Exercise Price at the time by $.01 or more.

<PAGE>



     (f) Adjustments: Additional Shares, Securities or Assets. In the event that
at any time, as a result of an adjustment made pursuant to this Section 5,
Holder shall, upon exercise of this Warrant, become entitled to receive shares
and/or other securities or assets (other than Common Stock) then, wherever
appropriate, all references herein to shares of Common Stock shall be deemed to
refer to and include such shares and/or other securities or assets; and
thereafter the number of such shares and/or other securities or assets shall be
subject to adjustment from time to time in a manner and upon terms as nearly
equivalent as practicable to the provisions of this Section 5.

     6. Fractional Interests.
        ---------------------

     No fractional shares or scrip representing fractional shares shall be
issuable upon the exercise of this Warrant, but on exercise of this Warrant,
Holder may purchase only a whole number of Warrant Shares. If, on exercise of
this Warrant, Holder would be entitled to a fractional share of Common Stock or
a right to acquire a fractional share of Common Stock, such fractional share
shall be disregarded and the number of Warrant Shares issuable upon exercise
shall be the next higher number of shares.

      7. Reservation of Shares.
         ---------------------

     The Company shall at all times reserve for issuance such number of
authorized and unissued shares of Common Stock (or other securities substituted
therefor as herein above provided) as shall be sufficient for the exercise of
this Warrant and payment of the Exercise Price. The Company covenants and agrees
that upon the exercise of this Warrant, all of the Warrant Shares issuable upon
such exercise shall be duly and validly issued, fully paid, nonassessable and
not subject to preemptive rights, rights of first refusal or similar rights of
any person or entity.

     8. Restrictions on Transfer.
        ------------------------

     (a) Registration or Exemption Required. This Warrant has been issued in a
transaction exempt from the registration requirements of the Securities Act by
virtue of Regulation D promulgated thereunder and exempt from state registration
under applicable state laws. This Warrant and the Warrant Shares issuable upon
the exercise of this Warrant may not be pledged, transferred, sold or assigned
except pursuant to an effective registration statement or unless the Company has
received an opinion from the Company's counsel to the effect that such
registration is not required, or the Holder has furnished to the Company an
opinion of the Holder's counsel, which counsel shall be reasonably satisfactory
to the Company, to the effect that such registration is not required; the
transfer complies with any applicable state securities laws; and, if no
registration covering the resale of the Warrant Shares is effective at the time
the Warrant Shares are issued, the Holder consents to a legend being placed on
certificates for the Warrant Shares stating that the securities have not been
registered under the Securities Act and referring to such restrictions on
transferability and sale.

     (b) Assignment. If Holder can provide the Company with reasonably
satisfactory evidence that the conditions of subsection (a) above regarding
registration or exemption have been satisfied, Holder may sell, transfer,
assign, pledge or otherwise dispose of this Warrant, in whole or in part. Holder
shall deliver a written notice to Company, substantially in the form of the
Assignment attached hereto as Exhibit B, indicating the person or persons to
whom this Warrant shall be assigned and the respective number of Warrant Shares
to be assigned to each assignee. The Company shall effect the assignment within
ten (10) days, and shall deliver to the assignee(s) designated by Holder a
Warrant or Warrants of like tenor and terms for the appropriate number of
Warrant Shares.

     9. Benefits of this Warrant.
        ------------------------

     Nothing in this Warrant shall be construed to confer upon any person other
than the Company and Holder any legal or equitable right, remedy or claim under
this Warrant and this Warrant shall be for the sole and exclusive benefit of the
Company and Holder.

<PAGE>


     10. Applicable Law.
         --------------

     This Warrant is issued under and shall for all purposes be governed by and
construed in accordance with the laws of the state of Colorado, without giving
effect to conflict of law provisions thereof.

     11. Loss of Warrant.
         ---------------

     Upon receipt by the Company of evidence of the loss, theft, destruction or
mutilation of this Warrant, and (in the case of loss, theft or destruction) of
indemnity or security reasonably satisfactory to the Company, and upon surrender
and cancellation of this Warrant, if mutilated, the Company shall execute and
deliver a new Warrant of like tenor and date.

     12. Notice or Demands.
         -----------------

Notices or demands pursuant to this Warrant to be given or made by Holder to or
on the Company shall be sufficiently given or made if sent by certified or
registered mail, return receipt requested, postage prepaid, and addressed, until
another address is designated in writing by the Company, to the address set
forth in Section 2(a) above. Notices or demands pursuant to this Warrant to be
given or made by the Company to or on Holder shall be sufficiently given or made
if sent by certified or registered mail, return receipt requested, postage
prepaid, and addressed, to the address of Holder set forth in the Company's
records, until another address is designated in writing by Holder.

     IN WITNESS WHEREOF, the undersigned has executed this Warrant as of the
27th day of January, 2000.

shares of the Common Stock of the Company together with any capital stock issued
in replacement of, in exchange for or otherwise in respect of such Common Stock,
that are: (i) issuable or issued to the Subscriber pursuant to the Investment
Agreement, and (ii) issuable or issued upon exercise of the Warrants; provided,
however, that notwithstanding the above, the following shall not be considered
Registrable Securities:

               (a) any Common Stock which would otherwise be deemed to be
Registrable Securities, if and to the extent that those shares of Common Stock
may be resold in a public transaction without volume limitations or other
material restrictions without registration under the Securities Act, including
without limitation, pursuant to Rule 144 under the Securities Act; and

               (b) any shares of Common Stock which have been sold in a private
transaction in which the transferor's rights under this Agreement are not
assigned.

          2.2 Filing of Initial Registration Statement. The Company shall, by
the Filing Deadline, file a registration statement ("Registration Statement") on
Form SB-2 (or other suitable form, at the Company's discretion, but subject to
the reasonable approval of Subscriber), covering the resale of a number of

<PAGE>

shares of Common Stock as Registrable Securities equal to at least Twenty
Million (20,000,000) shares of Common Stock and shall cover, to the extent
allowed by applicable law, such indeterminate number of additional shares of
Common Stock that may be issued or become issuable as Registrable Securities by
the Company pursuant to Rule 416 of the Securities Act. In the event that the
Company has not filed the Registration Statement by the Filing Deadline, then
the Company shall pay to Subscriber an amount equal to $250, in cash, for each
Business Day after the Filing Deadline until such Registration Statement is
filed, payable within ten (10) Business Days following the end of each calendar
month in which such payments accrue.

          2.3 [Intentionally Left Blank].

          2.4 Registration Effective Date. The Company shall use its best
efforts to have the Registration Statement declared effective by the SEC (the
date of such effectiveness is referred to herein as the "Effective Date") by the
Due Date.

          2.5 [Intentionally Left Blank].

          2.6 [Intentionally Left Blank].

          2.7 Shelf Registration. The Registration Statement shall be prepared
as a "shelf" registration statement under Rule 415, and shall be maintained
effective until all Registrable Securities are resold pursuant to the
Registration Statement.


          2.8 Supplemental Registration Statement. Anytime the Registration
Statement does not cover a sufficient number of shares of Common Stock to cover
all outstanding Registrable Securities, the Company shall promptly prepare and
file with the SEC such Supplemental Registration Statement and the prospectus
used in connection with such registration statement as may be necessary to
comply with the provisions of the Securities Act with respect to the disposition
of all such Registrable Securities and shall use its best efforts to cause such
Supplemental Registration Statement to be declared effective as soon as
possible.

     3. Obligations of the Company. Whenever required under this Agreement to
effect the registration of any Registrable Securities, the Company shall, as
expeditiously and reasonably possible:

          (a) Prepare and file with the Securities and Exchange Commission
("SEC") a Registration Statement with respect to such Registrable Securities and
use its best efforts to cause such Registration Statement to become effective
and to remain effective until all Registrable Securities are resold pursuant to
such Registration Statement, notwithstanding any Termination or Automatic
Termination (as each is defined in the Investment Agreement) of the Investment
Agreement.

          (b) Prepare and file with the SEC such amendments and supplements to
such Registration Statement and the prospectus used in connection with such
Registration Statement ("Amended Registration Statement") or prepare and file
any additional registration statement ("Additional Registration Statement,"
together with the Amended Registration Statement, "Supplemental Registration
Statements") as may be necessary to comply with the provisions of the Securities
Act with respect to the disposition of all securities covered by such
Supplemental Registration Statements or such prior registration statement and to
cover the resale of all Registrable Securities.

          (c) Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them.

          (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 the jurisdictions in which the Holders are located, of such other

<PAGE>

jurisdictions as shall be reasonably requested by the Holders of the Registrable
Securities covered by such Registration Statement and of all other jurisdictions
where legally required, 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 consent to service of process in any such states or
jurisdictions.

          (e) [Intentionally Omitted].

          (f) As promptly as practicable after becoming aware of such event,
notify each Holder of Registrable Securities of the happening of any event of
which the Company has knowledge, as a result of which the prospectus included in
the Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, use its best efforts promptly to prepare a
supplement or amendment to the Registration Statement to correct such untrue
statement or omission, and deliver a number of copies of such supplement or
amendment to each Holder as such Holder may reasonably request.

          (g) Provide Holders with notice of the date that a Registration
Statement or any Supplemental Registration Statement registering the resale of
the Registrable Securities is declared effective by the SEC, and the date or
dates when the Registration Statement is no longer effective.

          (h) Provide Holders and their representatives the opportunity and a
reasonable amount of time, based upon reasonable notice delivered by the
Company, to conduct a reasonable due diligence inquiry of Company's pertinent
financial and other records and make available its officers and directors for
questions regarding such information as it relates to information contained in
the Registration Statement.

          (i) Provide Holders and their representatives the opportunity to
review the Registration Statement and all amendments or supplements thereto
prior to their filing with the SEC by giving the Holder at least ten (10)
business days advance written prior to such filing.

          (j) Provide each Holder with prompt notice of the issuance by the SEC
or any state securities commission or agency of any stop order suspending the
effectiveness of the Registration Statement or the initiation of any proceeding
for such purpose. The Company shall use its best efforts to prevent the issuance
of any stop order and, if any is issued, to obtain the removal thereof at the
earliest possible date.

          (k) Use its best efforts to list the Registrable Securities covered by
the Registration Statement with all securities exchanges or markets on which the
Common Stock is then listed and prepare and file any required filing with the
NASD, American Stock Exchange, NYSE and any other exchange or market on which
the Common Stock is listed.

     4. Piggyback Registration. If anytime prior to the date that the
Registration Statement is declared effective or during any Ineffective Period
(as defined in the Investment Agreement) the Company proposes to register
(including for this purpose a registration effected by the Company for
shareholders other than the Holders) any of its Common Stock under the
Securities Act in connection with the public offering of such securities solely
for cash (other than a registration relating solely for the sale of securities
to participants in a Company stock plan or a registration on Form S-4
promulgated under the Securities Act or any successor or similar form
registering stock issuable upon a reclassification, upon a business combination
involving an exchange of securities or upon an exchange offer for securities of
the issuer or another entity), the Company shall, at such time, promptly give
each Holder written notice of such registration (a "Piggyback Registration
Statement"). Upon the written request of each Holder given by fax within ten
(10) days after mailing of such notice by the Company, the Company shall cause
to be included in such registration statement under the Securities Act all of
the Registrable Securities that each such Holder has requested to be registered
("Piggyback Registration") to the extent such inclusion does not violate the
registration rights of any other security holder of the company granted prior to
the date hereof; provided, however, that nothing herein shall prevent the
Company from withdrawing or abandoning such registration statement prior to its
effectiveness.

     5. Limitation on Obligations to Register under a Piggyback Registration. In
the case of a Piggyback Registration pursuant to an underwritten public offering
by the Company, if the managing underwriter determines and advises in writing
that the inclusion in the related Piggyback Registration Statement of all
Registrable Securities proposed to be included would interfere with the
successful marketing of the securities proposed to be registered by the Company,

<PAGE>

then the number of such Registrable Securities to be included in such Piggyback
Registration Statement, to the extent any such Registrable Securities may be
included in such Piggyback Registration Statement, shall be allocated among all
Holders who had requested Piggyback Registration pursuant to the terms hereof,
in the proportion that the number of Registrable Securities which each such
Holder seeks to register bears to the total number of Registrable Securities
sought to be included by all Holders. If required by the managing underwriter of
such an underwritten public offering, the Holders shall enter into an agreement
limiting the number of Registrable Securities to be included in such Piggyback
Registration Statement and the terms, if any, regarding the future sale of such
Registrable Securities.

     6. Dispute as to Registrable Securities. In the event the Company believes
that shares sought to be registered under Section 2 or Section 4 by Holders do
not constitute "Registrable Securities" by virtue of Section 2.1 of this
Agreement, and the status of those shares as Registrable Securities is disputed,
the Company shall provide, at its expense, an Opinion of Counsel, reasonably
acceptable to the Holders of the Securities at issue (and satisfactory to the
Company's transfer agent to permit the sale and transfer), that those securities
may be sold immediately, without volume limitation or other material
restrictions, without registration under the Securities Act, by virtue of Rule
144 or similar provisions.

     7. Furnish Information. At the Company's request, each Holder shall furnish
to the Company such information regarding Holder, the Registrable Securities
held by it, and the intended method of disposition of such securities to the
extent required to effect the registration of its Registrable Securities or to
determine that registration is not required pursuant to Rule 144 or other
applicable provision of the Securities Act. The Company shall include all
information provided by such Holder pursuant hereto in the Registration
Statement, substantially in the form supplied, except to the extent such
information is not permitted by law.

     8. Expenses. All expenses, other than commissions and fees and expenses of
counsel to the selling Holders, incurred in connection with registrations,
filings or qualifications pursuant hereto, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees, fees
and disbursements of counsel for the Company, shall be borne by the Company.

     9. Indemnification. In the event any Registrable Securities are included in
a Registration Statement under this Agreement:

          (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, the officers, directors, partners, legal counsel, and
accountants of each Holder, any underwriter (as defined in the Securities Act,
or as deemed by the Securities Exchange Commission, or as indicated in a
registration statement) for such Holder and each person, if any, who controls
such Holder or underwriter within the meaning of Section 15 of the Securities
Act or the Exchange Act, against any losses, claims, damages, or liabilities
(joint or several) to which they may become subject under the Securities Act,
the Exchange Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements or omissions: (i) any untrue
statement or alleged untrue statement of a material fact contained in such
registration statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, or (ii) the omission
or alleged omission to state therein a material fact required to be stated
therein, or necessary to make the statements therein not misleading, and the
Company will reimburse each such Holder, officer or director, underwriter or
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 9(a) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability, or action if such settlement is effected
without the consent of the Company (which consent shall not be unreasonably
withheld), nor shall the Company be liable in any such case for any such loss,
claim, damage, liability, or action to the extent that it arises out of or is
based upon a violation which occurs in reliance upon and in conformity with

<PAGE>

written information furnished expressly for use in connection with such
registration by any such Holder, officer, director, underwriter or controlling
person; provided however, that the above shall not relieve the Company from any
other liabilities which it might otherwise have.

          (b) Each Holder of any securities included in such registration being
effected shall indemnify and hold harmless the Company, its directors and
officers, each underwriter and each other person, if any, who controls (within
the meaning of the Securities Act) the Company or such other indemnified party,
against any liability, joint or several, to which any such indemnified party may
become subject under the Securities Act or any other statute or at common law,
insofar as such liability (or actions in respect thereof) arises out of or is
based upon (i) any untrue statement or alleged untrue statement of any material
fact contained, on the effective date thereof, in any registration statement
under which securities were registered under the Securities Act at the request
of such Holder, any preliminary prospectus or final prospectus contained
therein, or any amendment or supplement thereto, or (ii) any omission or alleged
omission by such Holder to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in such registration
statement, preliminary or final prospectus, amendment or supplement thereto in
reliance upon and in conformity with information furnished in writing to the
Company by such Holder specifically for use therein. Such Holder shall reimburse
any indemnified party for any legal fees incurred in investigating or defending
any such liability; provided, however, that such Holder's obligations hereunder
shall be limited to an amount equal to the proceeds to such Holder of the
securities sold in any such registration; and provided further, that no Holder
shall be required to indemnify any party against any liability arising from any
untrue or misleading statement or omission contained in any preliminary
prospectus if such deficiency is corrected in the final prospectus or for any
liability which arises out of the failure of such party to deliver a prospectus
as required by the Securities Act.

          (c) Promptly after receipt by an indemnified party under this Section
9 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 9, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume, the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonably incurred fees and
expenses of one such counsel to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential conflicting
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if materially prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 9, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 9.

          (d) In the event that the indemnity provided in paragraphs (a) and/or
(b) of this Section 9 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and each Holder agree to
contribute to the aggregate claims, losses, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Holders may be subject in such proportion as is appropriate to reflect the
relative fault of the Company and the Holders in connection with the statements
or omissions which resulted in such Losses. Relative fault shall be determined
by reference to whether any alleged untrue statement or omission relates to
information provided by the Company or by the Holders. The Company and the
Holders agree that it would not be just and equitable if contribution were
determined by pro rata allocation or any other method of allocation that does
not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section 9,
each person who controls a Holder of Registrable Securities within the meaning
of either the Securities Act or the Exchange Act and each director, officer,
partner, employee and agent of a Holder shall have the same rights to
contribution as such holder, and each person who controls the Company within the
meaning of either the Securities Act or the Exchange Act and each director and
officer of the Company shall have the same rights to contribution as the
Company, subject in each case to the applicable terms and conditions of this
paragraph (d).

<PAGE>


          (e) The obligations of the Company and Holders under this Section 9
shall survive the resale, if any, of the Common Stock, the completion of any
offering of Registrable Securities in a Registration Statement under this
Agreement, and otherwise.

     10. Reports Under Exchange Act. With a view to making available to the
Holders the benefits of Rule 144 promulgated under the Securities Act and any
other rule or regulation of the SEC that may at any time permit a Holder to sell
securities of the Company to the public without registration, the Company agrees
to:

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

          (b) use its best efforts to file with the SEC in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act.

     11. Amendment of Registration Rights. Any provision of this Agreement may
be amended and 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 written consent of each Holder affected
thereby. Any amendment or waiver effected in accordance with this paragraph
shall be binding upon each Holder, each future Holder, and the Company.

     12. Notices. All notices required or permitted under this Agreement shall
be made in writing signed by the party making the same, shall specify the
section under this Agreement pursuant to which it is given, and shall be
addressed if to (i) the Company at: U.S. Microbics, Inc.; Attn: Robert C. Brehm;
5922-B Fransworth Court; Carlsbad, CA 92008; Telephone: (760) 918-1860,
Facsimile: (760) 918-1855; Email: [email protected] (or at such other location
as directed by the Company in writing) and (ii) the Holders at their respective
last address as the party as shown on the records of the Company. Any notice,
except as otherwise provided in this Agreement, shall be made by fax and shall
be deemed given at the time of transmission of the fax.

     13. Termination. This Agreement shall terminate on the date all Registrable
Securities cease to exist (as that term is defined in Section 2.1 hereof); but
without prejudice to (i) the parties' rights and obligations arising from
breaches of this Agreement occurring prior to such termination (ii) other
indemnification obligations under this Agreement.

     14. Assignment. No assignment, transfer or delegation, whether by operation
of law or otherwise, of any rights or obligations under this Agreement by the
Company or any Holder, respectively, shall be made without the prior written
consent of the majority in interest of the Holders or the Company, respectively;
provided that the rights of a Holder may be transferred to a subsequent holder
of the Holder's Registrable Securities (provided such transferee shall provide
to the Company, together with or prior to such transferee's request to have such
Registrable Securities included in a Registration, a writing executed by such
transferee agreeing to be bound as a Holder by the terms of this Agreement), and
the Company hereby agrees to file an amended registration statement including
such transferee or a selling security holder thereunder; and provided further
that the Company may transfer its rights and obligations under this Agreement to
a purchaser of all or a substantial portion of its business if the obligations
of the Company under this Agreement are assumed in connection with such
transfer, either by merger or other operation of law (which may include without
limitation a transaction whereby the Registrable Securities are converted into
securities of the successor in interest) or by specific assumption executed by
the transferee.

     15. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Colorado applicable to agreements made
in and wholly to be performed in that jurisdiction, except for matters arising
under the Securities Act or the Exchange Act, which matters shall be construed
and interpreted in accordance with such laws. Any dispute arising out of or
relating to this Agreement or the breach, termination or validity hereof shall
be finally settled by the federal or state courts located in San Diego County,
California.

     16. Execution in Counterparts Permitted. This Agreement may be executed in
any number of counterparts, each of which shall be enforceable against the
parties actually executing such counterparts, and all of which together shall
constitute one (1) instrument.

     17. Specific Performance. The Holder shall be entitled to the remedy of
specific performance in the event of the Company's breach of this Agreement, the
parties agreeing that a remedy at law would be inadequate.

<PAGE>


     18. Indemnity. Each party shall indemnify each other party against any and
all claims, damages (including reasonable attorney's fees), and expenses arising
out of the first party's breach of any of the terms of this Agreement.

     19. Entire Agreement; Written Amendments Required. This Agreement,
including the Exhibits attached hereto, the Investment Agreement, the Common
Stock certificates, and the other documents delivered pursuant hereto constitute
the full and entire understanding and agreement between the parties with regard
to the subjects hereof and thereof, and no party shall be liable or bound to any
other party in any manner by any warranties, representations or covenants except
as specifically set forth herein or therein. Except as expressly provided
herein, neither this Agreement nor any term hereof may be amended, waived,
discharged or terminated other than by a written instrument signed by the party
against whom enforcement of any such amendment, waiver, discharge or termination
is sought.


     IN WITNESS WHEREOF, the undersigned have executed this Agreement as of this
14th day of March, 2000.
