                      BRIDGE LOAN AND INVESTMENT AGREEMENT

         This Bridge Loan and Investment Agreement (the "AGREEMENT"), submitted
as of the date set forth on the Signature Page, is between Redline Performance
Products, Inc., a Minnesota corporation (the "COMPANY"), and the undersigned
investor (the "INVESTOR").

                                    RECITALS

         The Company needs capital to fund its operations. The Investor desires
to lend funds to the Company on the terms and conditions set forth in this
Agreement. Investors may lend up to a minimum of $300,000 and a maximum of
$700,000 in principal amount to the Company on terms and conditions equivalent
to those set forth in this Agreement. The Company may sell an additional
$300,000 in principal amount of promissory notes to meet additional demand. The
Company has engaged Dougherty & Company LLC (the "AGENT") as its exclusive agent
in connection with the sale of promissory notes and warrants (the "BRIDGE
PLACEMENT"), and the sale of up to $5,000,000 in shares of the Company's Series
A Preferred Stock (the "SERIES A FINANCING"), including shares of Series A
Preferred Stock issuable upon conversion of the promissory notes.

                                    AGREEMENT

         In consideration of the foregoing, the mutual promises set forth
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

1.)      Investment. The Investor hereby purchases: (i) a 10% Unsecured
Convertible Subordinated Promissory Note (the "BRIDGE NOTE"), in substantially
the form of EXHIBIT A attached to and incorporated into this Agreement, which is
convertible into shares of the Company's Series A Preferred Stock (the
"CONVERSION SHARES"), in the principal dollar amount set forth on the Signature
Page and (ii) a warrant (the "BRIDGE WARRANT") in substantially the form of
EXHIBIT B attached to and incorporated into this Agreement, to purchase one
share of the Company's $0.01 par value per share common stock (the "COMMON
STOCK") for every $2.00 in principal amount of the Bridge Note (the "WARRANT
SHARES") and hereby tenders the Investor's check payable to "Redline Performance
Products, Inc." in the aggregate dollar amount set forth on the Signature Page.

         The information contained in this Agreement is only a summary of the
terms and provisions of the Bridge Notes and the Bridge Warrants, and is
qualified by more detailed information included in the form of Bridge Note and
the form of Bridge Warrant. If the terms of this Agreement conflict with the
terms of the Bridge Note or the Bridge Warrant, the terms of the Bridge Note and
the Bridge Warrant shall control. By execution of this Agreement, the Investor
acknowledges that the Company is relying upon the accuracy and completeness of
the representations contained in this Agreement in complying with its
obligations under applicable securities laws. The Bridge Note, the Bridge
Warrant, the Conversion Shares and the Warrant Shares are collectively referred
to in this Agreement as the "SECURITIES."

2.)      Loan/Promissory Note. The Investor agrees, on the terms and subject to
the conditions hereinafter set forth, to purchase a Bridge Note in the principal
amount set forth on the Signature Page. The Company agrees to issue in the name
of the Investor, a Bridge Note in substantially the form attached hereto as
Exhibit A.

3.)      Payment of Principal and Interest. All outstanding principal and
accrued interest on the Bridge Notes shall be due and payable by the Company on
the earlier of: (i) the date six (6) months from the date of original

                                       1.

<PAGE>

issuance of the Bridge Note and (ii) the date on which the Company completes the
sale of shares of Series A Preferred Stock which generates gross proceeds of at
least Two Million Dollars ($2,000,000). Each of the foregoing dates is referred
to in this Agreement as a "MATURITY DATE" or "MATURITY". The Bridge Note shall
accrue interest at the rate of ten percent (10%) per annum.

4.)      Extension of Maturity Date. If the Company is unable to repay the
Bridge Note principal and interest on or before the Maturity Date, the Company
may, at its sole discretion, extend the Maturity Date for a period of up to
ninety (90) days (the "EXTENSION PERIOD"). If the Company elects to extend the
Maturity Date, the Company will issue an additional Bridge Warrant (the
"ADDITIONAL BRIDGE WARRANT") to the holder of the Bridge Note on each of the
15th, 45th and 75th day of the Extension Period if the Bridge Loan principal and
interest has not been paid as of each such date. The number of shares of Common
Stock subject to each Additional Bridge Warrant shall be equal to 25% of the
number of shares of Common Stock subject to the original Bridge Warrant issued
to the Investor. During the Extension Period, the Bridge Note shall accrue
interest at the rate of fifteen percent (15%) per annum.

5.)      Subordination. The payment of principal and interest under the Bridge
Note is not secured by any collateral and is subordinated to the payment by the
Company of "SENIOR INDEBTEDNESS" as defined in the Bridge Note. Payment of
principal or interest may not be made on the Bridge Note if the Company is in
default, or if the making of any payment would result in a default, with respect
to the payment of amounts of any Senior Indebtedness.

6.)      Conversion. All of the principal, but not the interest, payable
pursuant to each Bridge Note shall automatically convert into the Conversion
Shares at such time as the Company generates gross proceeds of at least
$2,000,000 (the "MINIMUM AMOUNT") from the sale of shares of the Company's
Series A Preferred Stock in the Series A Financing. The principal amount of
Bridge Notes converted into Conversion Shares will not be included in gross
proceeds to determine sale of the Minimum Amount. The price of each Conversion
Share shall be equal to the lower of: (i) $1.00 or (ii) 80% of the price per
share of the Company's Series A Preferred Stock sold in the Series A Financing.
Upon conversion of the Bridge Note the Company will pay to the holder all
accrued interest thereon.

7.)      Default. The Company shall be in default under this Agreement and under
the Bridge Note upon the happening after the date of this Agreement of any
nonpayment, when due, of any amount payable to the holder under the Bridge Note.
In the event of a default: (a) the holders of Bridge Notes shall have the right,
at their option and not subject to demand or notice, to declare all or any part
of the Bridge Notes immediately due and payable, and (b) the holders of Bridge
Notes may exercise, in addition to the rights and remedies granted in this
Agreement, all of the rights and remedies of a holder under the Bridge Note and
under applicable law.

8.)      Bridge Warrant. In conjunction with the purchase of a Bridge Note by
the Investor, the Company will issue to the Investor a Bridge Warrant in
substantially the form attached to this Agreement as Exhibit B. The Bridge
Warrant will entitle the Investor to purchase one share of Common Stock for
every $2.00 in principal amount of the Bridge Note. The Bridge Warrant will have
an exercise price of $1.00 per share, will be exercisable one hundred eighty
(180) days after issuance and will expire five (5) years from the date of
issuance.

9.)      Reservation of Shares of Common Stock. The Company shall, during the
time that the Bridge Note, the Conversion Shares or the Bridge Warrant remain
outstanding, reserve and keep available from its authorized but unissued shares
of Common Stock, a sufficient number of shares to issue the shares of Common
Stock issuable upon conversion of the Conversion Shares and the Warrant Shares.

         necessary to the authorization, issuance, and delivery of the
         Securities will be taken prior to issuance of the Securities.

         (c)      The Bridge Notes and Bridge Warrants, when issued and
         delivered to the Investor, will constitute valid and binding
         obligations of the Company in accordance with their terms, except as

         insolvency, moratorium or similar laws affecting the rights of creditor
         generally and by judicial limitations on the right of specific
         performance. The Warrant Shares have been reserved for issuance and,

         validly issued and outstanding, fully paid, nonassessable.

12.)     Representations and Warranties of Investor. The Investor hereby

         reviewed the Company's Confidential Bridge Placement Memorandum dated
         May 1, 2000, and has obtained all information about the Company as the
         Investor believes relevant to the decision to purchase the Securities.
         The Investor has also had the opportunity to ask questions of, and to
         receive answers from, the Company or an agent or a representative of
         the Company concerning the terms and conditions of the investment and
         the business and affairs of the Company and to obtain any additional
         information necessary to verify such information, and the Investor has
         received such information concerning the Company as the Investor
         considers necessary or advisable in order to form a decision concerning
         an investment in the Company.

         The Investor understands that any business plan or similar document
         which the Investor may have been shown or of which the Investor may
         have been furnished a copy, is not a prospectus or comprehensive
         placement memorandum, offering circular, offering statement, or similar
         document. Any such document was not prepared, and the Investor
         understands that any such document was not prepared, with the purpose
         of providing full and accurate disclosure to investors. The Investor
         understands that any such document has been furnished to the Investor
         only as part of an overall furnishing of information about the Company
         and that the Investor has viewed the information set forth therein with
         a critical frame of mind and, to the extent that information contained
         in any such document was deemed by the Investor to be important
         information in making an investment decision, the Investor has
         discussed such information with the officers and other personnel of the
         Company in order to form a better judgment regarding the accuracy and
         adequacy of such information. The Investor agrees that no statement in
         any document, even if framed as a factual statement, will, of itself,
         constitute a factual representation by the Company in light of the
         various purposes for which any such document may have been created.

         understands that this transaction has not been reviewed or approved by
         the United States Securities and Exchange Commission (the "COMMISSION")
         or by any state securities or other authority and, because of the small
         number of persons solicited to invest in the Securities and the private
         nature of the placement, that all documents, records, and books
         pertaining to this investment have been made available to the Investor
         and the Investor's representatives, such as attorneys, accountants
         and/or purchaser representatives.

         undertaking, need or indebtedness.

         prospective investment in the Securities. The Investor has obtained, to
         the extent the Investor deems necessary, personal and professional
         advice with respect to the risks inherent in the investment in the
         Securities in light of the Investor's financial condition and
         investment needs. The Investor has been given access to full and
         complete information regarding the Company and has utilized such access

         person, trust, or organization.

         (j)      Subscription. The Investor understands that the payment made
         to the Company may immediately become funds of and may be used by the
         Company once accepted. The Company is free to reject any subscription
         in whole or in part. The Investor understands that if the Company
         determines to reject this subscription, any funds returned to the
         Investor will be without deduction therefrom or interest thereon.

                           INVESTOR MUST INITIAL HERE If the Investor is an
                           entity, the individual(s) signing on behalf of the
                           Investor and the Investor, jointly and severally,
                           agree and certify that this Agreement has been duly
                           authorized by all necessary action on the part of the
                           Investor, has been duly executed by an authorized
                           representative of the Investor, and is a legal,
                           valid, and binding obligation of the Investor
                           enforceable in accordance with its terms.

14.)     Investment Purpose in Acquiring the Securities. The Investor and the
Company acknowledge that the Securities have not been registered under the Act
or applicable state securities laws and that the Securities will be issued to
the Investor in reliance on exemptions from the registration requirements of the
Act and applicable state securities laws and in reliance on the Investor's and
the Company's representations and agreements contained herein. The Investor is
acquiring the Securities for the account of the Investor for investment purposes
only and not with a view to their resale or distribution. The Investor has no
present intention to divide his, her or its participation with others or to
resell or otherwise dispose of all or any part of the Securities. In making
these representations, the Investor understands that, in the view of the
Commission, exemption of the Securities from the registration requirements of
the Act would not be available if, notwithstanding the representations of the
Investor, the Investor has in mind merely acquiring the Securities for resale
upon the occurrence or non-occurrence of some predetermined event.

15.)     Compliance with Securities Act. The Investor agrees that if the
Securities or any part thereof are sold or distributed in the future, the
Investor shall sell or distribute them pursuant to the requirements of the Act
and applicable state securities laws. The Investor agrees that the Investor will
not transfer any part of the Securities without: (i) obtaining a "no action"
letter from the Commission and applicable state securities commissions; (ii)
obtaining an opinion of counsel satisfactory in form and substance to the
Company to the effect that such transfer is exempt from the registration
requirements under the Act and applicable state securities laws; or (iii)
registration.

                                       7.

16.)     Restriction on Transfer After a Public Offering. The Investor
understands that the Company at a future date may file a registration or
offering statement (the "REGISTRATION STATEMENT") with the Commission to
facilitate a public offering of its securities. The Investor agrees, for the
benefit of the Company, that should such an initial public offering be made and
should the managing underwriter of such offering require, the Investor will not,
without the prior written consent of the Company and such underwriter, during
the "Lockup Period" as defined herein: (i) sell, transfer or otherwise dispose
of, or agree to sell, transfer or otherwise dispose of any of the Securities
beneficially owned by the Investor during the Lockup Period; (ii) sell, transfer
or otherwise dispose of, or agree to sell, transfer or otherwise dispose of any
options, rights or warrants to purchase any of the Securities beneficially owned
by the Investor during the Lockup Period; or (iii) sell or grant, or agree to
sell or grant, options, rights or warrants with respect to any of the
Securities. The foregoing does not prohibit gifts to donees or transfers by will
or the laws of descent to heirs or beneficiaries provided that such donees,
heirs and beneficiaries shall be bound by the restrictions set forth herein. The
term "LOCKUP PERIOD" shall mean the lesser of (x) 180 days and (y) the period
during which Company officers and directors are restricted by the managing
underwriter from effecting any sales or transfers of the Company's common stock.
The Lockup Period shall commence on the effective date of the Registration
Statement.

17.)     Restrictive Legend. The Investor agrees that the Company may place one
or more restrictive legends on any certificates evidencing the Securities,
including the Conversion Shares, containing substantially the following
language:

         The securities represented by this certificate have not been registered
         under the Securities Act of 1933, as amended, have not been registered
         under any state securities law, and are subject to a subscription and
         investment representation agreement. They may not be sold, offered for
         sale, transferred, assigned, pledged or otherwise distributed for value
         unless there is an effective registration under the Securities Act of
         1933, as amended, and under the applicable state securities laws, or
         the Company receives an opinion of counsel acceptable to the Company
         stating that such transaction is exempt from registration and
         prospectus delivery requirements of the Securities Act of 1933, as
         amended, and under the applicable state securities laws.

         Sale or other transfer of these securities is further restricted for up
         to 180 days following an initial public offering of securities of the
         Company by the terms of a Subscription Agreement, a copy of which is
         available for inspection at the offices of the Company.

18.)     Stop Transfer Order. The Investor agrees that the Company may place a
stop transfer order with its registrar and transfer agent (if any) covering all
Securities.

19.)     Knowledge of Restrictions upon Transfer of the Securities. The Investor
understands that the Securities are not freely transferable and may in fact be
prohibited from sale for an extended period of time and that, as a consequence
thereof, the Investor must bear the economic risk of an investment in the
Securities for an indefinite period of time and may have extremely limited
opportunities to dispose of the Securities. The Investor realizes that there
will likely be no market for the Securities, and that there are significant
restrictions on the transferability thereof.

20.)     Lack of Availability of Rule 144 Under the Act. The Investor
understands and acknowledges that the Company has no obligation to undertake or
complete a public offering of its securities, that even if a public offering is
undertaken and successfully completed, the Securities subscribed for hereby will
remain subject to the restrictions on transferability described herein, and that
even if a public offering is undertaken and completed, the Investor may never be
able to sell its Securities pursuant to Rule 144 under the Act.

                                       8.

<PAGE>

         The Investor further understands and acknowledges that the Company
currently does not file periodic reports with the Commission pursuant to the
requirements of Sections 13 or 15(d) of the Securities Exchange Act of 1934, and
may not be obligated to file such reports at any time in the future. The
Investor also understands that the Company has not agreed to supply such other
information as would be required to enable routine sales of the Securities to be
made under the provisions of certain rules respecting "restricted securities,"
including Rule 144 promulgated under the Act by the Commission. Thus, the
Investor has been informed that the Company is not obligated to make publicly
available or to provide the Investor with the information required by Rule 144.

21.)     Relationship to Brokerage Firms. (Please answer the following questions
by initialing the appropriate response):

         (a)      ___ YES X NO: Are you a director, officer, partner, branch
         manager, registered representative, employee, shareholder of, or

         partner, branch manager, registered representative, employee,
         shareholder of, or similarly related to or employed by a brokerage
         firm?

         (If you answered YES to any of the foregoing questions, please attach a
         written explanation or contact the Company to provide additional
         information before the Investor's subscription can be considered.)

22.)     Delivery of Bridge Note and Bridge Warrant. Upon acceptance of this
Agreement by the Company, the Bridge Note and the Bridge Warrant will be
registered in the name of the Investor and will be delivered via certified mail
or overnight delivery to the address of the Investor set forth on the Signature
Page.

23.)     Binding Effect. Neither this Agreement nor any interest herein shall be
assignable by the Investor without the prior written consent of the Company. The
provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto, and their respective heirs, legal representatives,
successors and assigns.

24.)     Representations to Survive Delivery. The representations, warranties
and agreements of the Company and of the Investor contained in this Agreement
will remain operative and in full force and effect and will survive the receipt
of funds by the Company, and the issuance to the Investor of the Bridge Notes
and Bridge Warrants.

                                       9.

25.)     Indemnification. The Investor agrees to indemnify the Company, and each
current and future officer, director, employee, agent and shareholder of the
Company, against and to hold them harmless from any damage, loss, liability,
claim or expense including, without limitation, reasonable attorneys' fees
resulting from or arising out of the inaccuracy or alleged inaccuracy of any of
the representations, warranties or statements of the Investor contained in this
Agreement, including without limitation any violation or alleged violation of
the registration requirements of the Act or applicable state law in connection
with any subsequent sale of the Securities or any portion thereof by Investor.

26.)     Additional Information. The Investor shall supply such additional
information and documentation relating to Investor and any persons who have any
rights or interest in Investor as may be requested by the Company in order to
ensure compliance by the Company with applicable laws. If at any time prior to
the Company's execution of this Agreement, an adverse change occurs with respect
to the Investor such that the information, representations and warranties of the
Investor set forth in this Agreement are no longer accurate, the Investor shall
immediately notify the Company of the inaccuracy in writing and shall deliver
the updated, accurate information to the Company.

27.)     Miscellaneous Provisions.

         (a)      Arbitration. Any dispute regarding this Agreement or the
         Investor's investment in the Company (including without limitation
         claims pursuant to federal or state securities laws), including any
         claim which is made against any placement agent or broker-dealer
         involved in the offer or sale of the Securities, shall be resolved by
         arbitration which shall be the sole forum for resolution of any such
         disputes. Unless otherwise agreed by the parties, any such proceedings
         shall be brought in Minneapolis, Minnesota U.S.A. pursuant to the Rules
         and Code of Arbitration of the American Arbitration Association, except
         that if a bona fide claim is made against the Company, and a placement

Note No.: AB-12                                                Vista, California

         FOR VALUE RECEIVED, the undersigned, Redline Performance Products,
Inc., organized and existing under the laws of the State of Minnesota, whose
mailing address is 2520 Fortune Way, Vista, California 92083, and its successors
and assigns (the "BORROWER"), for value received, hereby unconditionally
promises to pay to the order of Industricorp & Co., Inc. FBO Twin City
Carpenters Pension Plan, a Minnesota-based pension plan, having a mailing
address of 312 Central Avenue, Minneapolis, MN 55414, attention Securities
Department, and their successors and assigns (the "LENDER"), at such place as
may be designated from time to time by the Lender, the principal sum of Two
Hundred Thousand and 00/100 Dollars ($200,000.00), together with accrued
interest thereon, at the rate of ten percent (10%) per annum, at or before 5:00
p.m. Vista, California time on January 21, 2001 ("MATURITY DATE"). This
promissory note (the "BRIDGE NOTE") is being issued in connection with a
placement of Bridge Notes and warrants to purchase shares of the Borrower's
common stock (the "BRIDGE WARRANT") being conducted by the Company to raise up
to $700,000 (plus up to an additional $300,000 to meet additional demand)
pursuant to the terms of a Bridge Loan and Investment Agreement. This Bridge
Note and the Holder hereof are entitled to all the benefits provided for in the
Bridge Loan and Investment Agreement, or which are referred to therein, pursuant
to which this indebtedness was incurred and is to be repaid. The provisions of
the Bridge Loan and Investment Agreement are incorporated herein by reference
with the same force and effect as if fully set forth herein.

<PAGE>

         1.)      Payment. All outstanding principal and accrued interest on the
Bridge Note shall be due and payable on the earlier of: (i) the date six (6)
months from the date of original issuance of the Bridge Note and (ii) the date
on which the Borrower generates gross proceeds of at least $2,000,000 (the
"MINIMUM AMOUNT") from the sale of shares of the Borrower's Series A Preferred
Stock in the a proposed placement of Series A Preferred Stock intended to raise
the Minimum Amount and up to $5,000,000 (the "SERIES A FINANCING"), unless all
principal and accrued interest hereunder shall have been paid or all principal
shall have been converted in accordance with the terms of this Bridge Note. Each
of the foregoing dates is referred to in this Bridge Note as the "MATURITY DATE"
or "MATURITY". All payments under this Section shall be made by check mailed by
the Borrower to the address of the Lender set forth above. Interest on the
unpaid principal balance of this Bridge Note shall be calculated on the basis of
a 360-day year comprised of twelve 30-day months. If the Borrower is unable to
repay the Bridge Note principal and interest on or before the Maturity Date, the
Company may, in its sole discretion, extend the Maturity Date for a period of up
to ninety (90) days (the "EXTENSION PERIOD"). If the Borrower elects to extend
the Maturity Date, the Company shall issue an additional Bridge Warrant (the
"ADDITIONAL BRIDGE WARRANT") to the holder of the Bridge Note on each of the
15th, 45th and 75th day of the Extension Period if the Bridge Loan principal and
interest has not been paid as of such dates. The number of shares of Common
Stock subject to each Additional Bridge Warrant shall be equal to 25% of the
number of shares of Common Stock subject to the original Bridge Warrant issued
to the Investor. During the Extension Period, the Bridge Note shall accrue
interest at the rate of fifteen percent (15%) per annum.

         2.)      Subordination. The term "SENIOR INDEBTEDNESS" shall mean all
principal of (and premium of, if any) and unpaid interest on all indebtedness of
the Borrower, and with respect to which the Borrower is a guarantor (but
excluding indebtedness guaranteed solely for the benefit of officers, directors,
employees or consultants of the Borrower), and except as provided to the
contrary herein, regardless of whether incurred on, before or after the date of
this Bridge Note: (i) for money borrowed from any bank, insurance company, or
other lending institution regularly engaged in the business of lending money,
whether or not secured; (ii) for amounts owed to TMAG Industries, Inc. as of the
date of this Bridge Note and (iii) in connection with any deferral, renewal or
extension of any indebtedness described in (i) or (ii) above or any debentures,
notes, or other evidence of the Borrower's indebtedness issued in exchange for
indebtedness described in (i) or (ii) above. The Borrower covenants and agrees
and the Lender, by acceptance hereof, covenants, expressly for the benefit of
the present and future holders of Senior Indebtedness, that the payment of the
principal and the interest on this Bridge Note is expressly subordinated in
right of payment to the payment in full of all principal and interest of Senior
Indebtedness of the Borrower. Notwithstanding the foregoing, payment of
principal or interest may be made hereunder unless the Company is in default, or
if the making of any payment hereunder would result in a default, with respect
to the payment of amounts of any Senior Indebtedness.

         3.)      Conversion. All of the principal, but not the interest,
payable pursuant to the Bridge Note shall automatically convert into shares of
the Borrower's Series A Preferred Stock upon the sale of shares of the
Borrower's Series A Preferred Stock in the Minimum Amount. Upon conversion of
the Bridge Note the Borrower will pay to the holder all accrued interest

                                       2.

<PAGE>

thereon. Upon conversion the Lender shall surrender this Bridge Note at the
principal office of the Borrower. The conversion shall be deemed to have been
made at the close of business on the Conversion Date. No fractional shares will
be issued in connection with any conversion of this Bridge Note. In lieu of any
fractional share which would otherwise be issuable, the Borrower shall pay cash.
The price of each share of Series A Preferred Stock shall be equal to the lower
of: (i) $1.00 and (ii) 80% of the price per share of the Company's Series A
Preferred Stock sold in the Series A Financing which generates gross proceeds of
not less than the Minimum Amount. The conversion price shall be appropriately
adjusted in the event of any stock split, recapitalization or similar
transaction.

         4.)      Compliance with Securities Laws and Other Transfer
Restrictions.

         (a)      The holder of this Bridge Note, by acceptance hereof, agrees,
         represents and warrants that this Bridge Note and the Conversion Shares
         which may be issued upon exercise hereof are being acquired for
         investment, that the holder has no present intention to resell or
         otherwise dispose of all or any part of this Bridge Note or any
         Conversion Shares, and that the holder will not offer, sell or
         otherwise dispose of all or any part of this Bridge Note or any
         Conversion Shares except under circumstances which will not result in a
         violation of the Act or applicable state securities laws. The Borrower
         may condition any transfer, sale, pledge, assignment or other
         disposition on the receipt, from the party to whom this Bridge Note is
         to be so transferred or to whom Conversion Shares are to be issued or
         so transferred, of any representations and agreements requested by the
         Borrower in order to permit such issuance or transfer to be made
         pursuant to exemptions from registration under federal and applicable
         state securities laws. Upon conversion of this Bridge Note, the holder
         hereof shall, if requested by the Borrower, confirm in writing holder's
         investment purpose and acceptance of the restrictions on transfer of
         the Conversion Shares, as well as any representations and agreements
         requested by the Borrower in order to permit the issuance of Conversion
         Shares to be made pursuant to exemptions from registration under
         federal and applicable state securities laws.

         (b)      If the Borrower conducts an Initial Public Offering of its
         Common Stock, the holder of the Bridge Note or any Conversion Shares
         shall not, without the prior written consent of the Borrower and the
         managing underwriter in such offering: (i) sell, transfer or otherwise
         dispose of, or agree to sell, transfer or otherwise dispose of the
         Bridge Note or Conversion Shares; (ii) sell, transfer or otherwise
         dispose of, or agree to sell, transfer or otherwise dispose of any
         right to purchase the Bridge Note or Conversion Shares; or (iii) sell
         or grant, or agree to sell or grant, options, rights or warrants with
         respect to the Bridge Note or Conversion Shares. Such restrictions
         shall be effective for a period of time equal to the period during
         which the managing underwriter imposes such transfer restrictions on
         the Borrower's officers and directors; provided, that in no event shall
         the restricted period applicable to a holder of this Bridge Note exceed
         one hundred twenty (180) days after effectiveness of the Borrower's
         registration statement filed under the Act with the Securities and
         Exchange Commission with respect to such offering.

                                       3.

<PAGE>

         (c)      In the event the holder of this Bridge Note desires to
         transfer this Bridge Note, the holder shall provide the Borrower with a
         Form of Assignment, in the form attached hereto describing the manner
         of such transfer, and an opinion of counsel (reasonably acceptable to
         the Borrower) that the proposed transfer may be effected without
         registration or qualification under applicable securities laws,
         whereupon such holder shall be entitled to transfer this Bridge Note in
         accordance with the notice delivered by such holder to the Borrower.
         If, in the opinion of the counsel referred to in this Subsection, the
         proposed transfer or disposition described in the written notice given
         may not be effected without registration or qualification of this
         Bridge Note, the Borrower shall give written notice thereof to the
         holder hereof, and such holder will limit its activities in respect to
         such proposed transfer or disposition as, in the opinion of such
         counsel, are permitted by law.

         (d)      The Borrower may place one or more restrictive legends on the
         Bridge Note or any certificates representing the Conversion Shares
         which set forth the restrictions contained herein, and may further
         place a "stop transfer" restriction in the Borrower's books and records
         with respect to the Bridge Note and any Conversion Shares. The
         restrictions set forth in this Bridge Note shall be binding upon any
         holder, donee, assignee or transferee of the Bridge Note or the
         Conversion Shares.

         5.)      Rights as Shareholder. Until one or more stock certificates
representing the of Conversion Shares issuable upon conversion of this Bridge
Note are issued (as evidenced by the appropriate entry on the books of the
Borrower or of a duly authorized transfer agent of the Borrower), no right to
vote or receive dividends or any other rights as a shareholder of the Borrower
shall exist, notwithstanding conversion of the Bridge Note. No such stock
certificates will be issued until the Bridge Note and all other documents and
information requested by the Company are delivered to the Company.

         6.)      Negative Covenant.

         (a)      The Company shall not transfer, sell, convey or otherwise
         encumber in any manner (other than to grant a license for marketing
         purposes to use one or more of the tradenames for which the Company has
         filed applications for trademark protection) the Technology Assets
         without the prior written consent of the holders of two-thirds of the
         principal dollar amount of the outstanding Bridge Notes, which dollar
         amount shall exclude any accrued interest on such outstanding Bridge
         Notes. Such consent shall not be unreasonably withheld. The negative
         covenant described in this Subsection 6(a) is referred to herein as the
         "NEGATIVE COVENANT." The intended effect of the Negative Covenant is to
         limit the Company's ability to transfer or encumber the Technology
         Assets. The Negative Covenant does not, and is not intended to, grant

         (c)      At such time as the Company determines that a transfer, sale,
         conveyance or other encumbrance of the Technology Assets is necessary
         or appropriate, the Company shall give each holder of record of
         outstanding Bridge Notes written notice ("NOTICE") of the Company's
         intention to undertake such a transfer, sale, conveyance or other
         encumbrance. The Notice shall include a general description of the
         terms of the proposed transaction and a consent form which the holder
         of the Bridge Note may use to indicate such holder's consent to the
         proposed transaction. If the holders of two-thirds of the principal
         dollar amount of outstanding Bridge Notes (excluding accrued interest
         thereon) do not consent to the proposed transaction within 30 days of
         delivery of the Notice, the Company shall not undertake the proposed
         transaction described in the Notice. Delivery of the Notice shall be to
         the most recent address included in the Company's records of holders of

         (d)      The Negative Covenant shall terminate with respect to each
         outstanding Bridge Note upon the earlier of: (i) the payment of the
         principal amount and accrued interest on such outstanding Bridge Note;
         (ii) the conversion of such outstanding Bridge Note into shares of the
         Company's capital stock; and (iii) the written agreement of the holders
         of all of the outstanding Bridge Notes.

         7.)      Miscellaneous Provisions.

         (a)      No amendment hereunder shall be effective unless in writing
         signed by the Borrower and the Lender and no waiver hereunder shall be
         effective unless in writing, signed by the party to be charged. Neither
         the failure on the part of the Lender in exercising any right or
         remedy, nor any single or partial exercise of any other right or
         remedy, shall operate as a waiver. The acceptance by the Lender of any
         payment hereunder which is less than payment in full of all amounts due
         and payable at the time of such payment shall not constitute a waiver
         of the right to exercise any of the options hereunder at that time or
         at any subsequent time.

         (b)      The Borrower hereby: (i) waives diligence, presentment, demand
         for payment, notice of dishonor, notice of non-payment, protest, notice
         of protest, and any and all other demands in connection with the
         delivery, acceptance, performance, default or enforcement of this
         Bridge Note, and (ii) except as provided in Section 1 of this Bridge
         Note, agrees that the Lender has, subject to the prior written request
         or approval of the Borrower, the right (but not the obligation) to
         grant any extension of time for payment of any indebtedness evidenced
         by this Bridge Note.

                                       5.

<PAGE>

         (c)      The terms and provisions hereof shall inure to the benefit of,
         and be binding upon, the respective successors and assigns of the
         Borrower and Lender. This Bridge Note shall be governed by and
         construed and enforced in accordance with the laws of the State of
         Minnesota without giving effect to such state's choice of law
         principles.

         (d)      No recourse for the payment of the principal of or any
         interest on this Bridge Note, or for any claim based hereon or
         otherwise in respect hereof, and no recourse under or upon any
         obligation, covenant or agreement of the Borrower in any Bridge Note,
         or because of the creation of any indebtedness represented thereby,
         shall be had against any incorporator, shareholder, officer or director
         as such, past, present or future, of the Borrower or of any successor
         corporation either directly or through the Borrower or any successor
         corporation, whether by virtue of any constitution, statute or rule of
         law or by the enforcement of any assessment or penalty or otherwise,
         all such liability being, by the acceptance hereof and as part of the
         consideration for the issue hereof, expressly waived and released.

         (e)      The Borrower covenants that during the period this Bridge Note
         is convertible, the Borrower will reserve from its authorized and
         unissued shares of common stock a sufficient number of shares to
         provide for the issuance of Conversion Shares upon the conversion of
         this Bridge Note, and shares of common stock upon conversion of the
         Conversion Shares. The Borrower further covenants that all Conversion
         Shares that may be issued upon the conversion of this Bridge Note will,
         upon payment and issuance, be duly authorized and issued, fully paid
         and nonassessable shares of the Borrower's common stock.

         (f)      Upon receipt by the Borrower of evidence reasonably
         satisfactory to it of the loss, theft, destruction or mutilation of
         this Bridge Note, and in case of loss, theft or destruction, of
         indemnity or security reasonably satisfactory to it, and upon
         reimbursement to the Borrower of all reasonable expenses incidental
         thereto, and upon surrender and cancellation of this Bridge Note, if
         mutilated, the Borrower will make and deliver a new Bridge Note of like
         tenor and dates as of such cancellation, in lieu of this Bridge Note.

         (g)      This Bridge Note has been issued pursuant to and is subject to
         the terms and provisions of that certain Bridge Loan and Investment
         Agreement of even date herewith between the Borrower and the Lender,
         the terms and provisions of which are incorporated herein by reference
         with the same force and effect as if fully set forth herein. To the
         extent the terms of the Bridge Note and the Bridge Loan and Investment
         Agreement are inconsistent, the terms of this Bridge Note shall
         control.

         (h)      All notices and other communications shall be by certified
         mail, return receipt requested, or by overnight delivery service to the
         address furnished to the Borrower in writing by the last holder of this
         Bridge Note who shall have furnished an address to the Borrower in
         writing. Delivery shall be deemed to have occurred on the date three

         delivery of such notice to a reputable overnight delivery service.

executed by its authorized representative, who certifies that he has all
necessary authority on behalf of the Borrower to execute this Bridge Note and
bind the Borrower to the terms hereof.

Void After 5:00 p.m. Vista, California time on July 21, 2005

                               WARRANT TO PURCHASE
                             SHARES OF COMMON STOCK
                                       OF
                       REDLINE PERFORMANCE PRODUCTS, INC.

Warrant No. AB-12                                                Shares: 100,000

         THIS CERTIFIES that, subject to the terms and conditions herein set
forth, Industricorp & Co., Inc. FBO Twin City Carpenters Pension Plan or
registered assigns, is entitled to purchase from REDLINE PERFORMANCE PRODUCTS,
INC., a Minnesota corporation (the "COMPANY"), at any time after one hundred
eighty (180) days from the date of original issuance of this warrant (the
"BRIDGE WARRANT") and prior to the time and date set forth above, One Hundred
Thousand (100,000) fully paid and nonassessable shares of $0.01 par value per
share common stock of the Company (such class of shares being referred to as the
"COMMON STOCK," and such shares of Common Stock which may be acquired upon
exercise of this Bridge Warrant being referred to as the "WARRANT SHARES"). This
Bridge Warrant is being issued in connection with a placement (the "BRIDGE
PLACEMENT") of promissory notes ("BRIDGE NOTES") and Bridge Warrants being
conducted by the Company to raise up $700,000 (plus up to an additional $300,000
to meet additional demand) and pursuant to the terms of a Bridge Loan and
Investment Agreement. This Bridge Warrant and the Holder hereof are entitled to
all the benefits provided for in the Bridge Loan and Investment Agreement, or
which are referred to therein to which this indebtedness was incurred and is to
be repaid. The provisions of the Bridge Loan and Investment Agreement are
incorporated herein by reference with the same force and effect as if fully set
forth herein.

         This Bridge Warrant is subject to the following terms and conditions:

<PAGE>

         1.)      Purchase Price. Subject to adjustment as hereinafter provided,
the purchase price of each Warrant Share shall be One and 00/100 Dollars
($1.00). The purchase price of one Warrant Share is referred to herein as the
"BRIDGE WARRANT PRICE."

         2.)      Adjustment of Bridge Warrant Price and Number of Warrant
Shares. The provisions in this Bridge Warrant relating to the Bridge Warrant
Price and the number of Warrant Shares to be issued upon exercise of this Bridge
Warrant shall be subject to adjustment from time to time as hereinafter
provided.

         (a)      Upon each adjustment of the Bridge Warrant Price, the Holder
         of this Bridge Warrant shall thereafter be entitled to purchase, at the
         Bridge Warrant Price resulting from such adjustment, the number of
         shares of Common Stock obtained by multiplying the Bridge Warrant Price
         in effect immediately prior to such adjustment by the number of shares
         of Common Stock purchasable hereto immediately prior to such adjustment
         and dividing the product thereof by the Bridge Warrant Price resulting
         from such adjustment.

         (b)      In case the Company shall at any time subdivide its
         outstanding Common Stock into a greater number of shares or declare a
         dividend payable in Common Stock, the Bridge Warrant Price in effect
         immediately prior to such subdivision shall be proportionately reduced
         and the number of shares of Common Stock purchasable pursuant to this
         Bridge Warrant shall be proportionately increased, and conversely, in
         case the Company's outstanding Common Stock shall be combined into a
         smaller number of shares, the Bridge Warrant Price in effect
         immediately prior to such combination shall be proportionately
         increased and the number of shares of Common Stock purchasable upon the
         exercise of this Bridge Warrant shall be proportionately reduced.

         (c)      If any capital reorganization or reclassification of the
         capital stock of the Company, or consolidation or merger of the Company
         with another corporation, or the sale of all or substantially all of
         its assets to another corporation shall be effected in such a way that
         holders of Common Stock shall be entitled to receive stock, securities
         or assets ("SUBSTITUTED PROPERTY") with respect to or in exchange for
         such Common Stock, then, as a condition of such reorganization,
         reclassification, consolidation, merger or sale, the Holder shall have
         the right to purchase and receive upon the basis and upon the terms and
         conditions specified in this Bridge Warrant, and in lieu of the Common
         Stock of the Company immediately theretofore purchasable and receivable
         upon the exercise of the rights represented hereby, such Substituted
         Property as would have been issued or delivered to the Holder if it had
         exercised this Bridge Warrant and had received upon exercise of this
         Bridge Warrant the Common Stock prior to such reorganization,
         reclassification, consolidation, merger, or sale. The Company shall not
         effect any such consolidation, merger, or sale, unless prior to the
         consummation thereof the successor corporation (if other than the
         Company) resulting from such consolidation or merger or the corporation
         purchasing such assets shall assume the obligation to deliver to the
         Holder such Substituted Property as, in accordance with the foregoing
         provisions, the Holder may be entitled to purchase.

                                       2.

<PAGE>

         (d)      If the Company takes any other action, or if any other event
         occurs which does not come within the scope of the provisions of
         Sections 2(b) or 2(c), but which should, in the Company's reasonable
         judgment, result in an adjustment in the Bridge Warrant Price and/or
         the number of shares subject to the Bridge Warrant in order to fairly
         protect the purchase rights of the Holder, an appropriate adjustment in
         such purchase rights shall be made by the Company.

         (e)      Upon any adjustment of the Bridge Warrant Price or the number
         of shares issuable upon of this Bridge Warrant, the Company shall give
         written notice thereof, by first-class mail, postage prepaid, addressed
         to the Holder at the address of the Holder as shown on the books of the
         Company, which notice shall state the Bridge Warrant Price resulting
         from such adjustment and the increase or decrease, if any, in the
         number of shares purchasable at such price upon the exercise of this
         Bridge Warrant, setting forth in reasonable detail the method of
         calculation and the facts upon which such calculation is based.

         3.)      No Fractional Shares. No fractional shares will be issued in
connection with any exercise of this Bridge Warrant. In lieu of any fractional
share which would otherwise be issuable, the Company shall pay cash equal to the
product of such fraction multiplied by the fair market value, as determined by
the Company's officers, of one share of Common Stock on the date of exercise.

         4.)      No Shareholder Rights. This Bridge Warrant shall not entitle
its holder to vote, receive dividends or exercise any of the rights of a
shareholder of the Company prior to exercise of this Bridge Warrant.

         5.)      Covenants of the Company. The Company covenants that during
the period this Bridge Warrant is exercisable, the Company will reserve from its
authorized and unissued shares of Common Stock a sufficient number of shares of
Common Stock to provide for the issuance of Warrant Shares upon the exercise of
this Bridge Warrant. The Company further covenants that all Warrant Shares that
may be issued upon the exercise of this Bridge Warrant will, upon payment and
issuance, be duly authorized and issued, fully paid and nonassessable shares of
Common Stock.

         6.)      Exercise of Bridge Warrant. This Bridge Warrant may be
exercised by the registered holder, in whole or in part, by the surrender of
this Bridge Warrant at the principal office of the Company, together with the
Exercise Form attached hereto duly executed, accompanied by payment in full of
the amount of the aggregate Bridge Warrant Price in cash, cashier's check or
bank draft. Upon partial exercise hereof, a new warrant or warrants containing
the same date and provisions as this Bridge Warrant shall be issued by the
Company to the registered holder for the number of Warrant Shares with respect
to which this Bridge Warrant shall not have been exercised. For each partial
exercise the holder shall purchase a minimum of five thousand (5,000) Warrant
Shares, or, if the number of Warrant Shares available for exercise under the
Bridge Warrant is less than such minimum number, the balance of the Warrant
Shares available for exercise under the Bridge Warrant. A Bridge Warrant shall
be deemed to have been

                                       3.

<PAGE>

exercised immediately prior to the close of business on the date the Company is
in receipt of this Bridge Warrant, a completed Exercise Form, all documents the
Company may reasonably request from the holder for the purpose of complying with
applicable securities and other laws, and payment for the number of Warrant
Shares being acquired upon exercise of this Bridge Warrant. The holder entitled
to receive the Warrant Shares issuable upon such exercise shall be treated for
all purposes as the holder of record of such Warrant Shares as of the close of
business on such date. After such date, the Company shall issue and deliver to
the holder or holders entitled to receive the same, a certificate or
certificates for the number of full Warrant Shares issuable upon such exercise,
together with cash in lieu of any fraction of a share, as provided above.

         7.)      Registration of Warrant Shares. The rights of the holder of
this Bridge Warrant to include Warrant Shares in a registered offering of
securities conducted by the Company are set forth in this Section 7. Upon any
closing of the Series A Placement, as such placement is described in the Bridge
Loan and Investment Agreement, the registration rights set forth in this Section
7 shall be superseded and replaced by the registration rights provided to
purchasers of shares of Series A Preferred Stock in the Series A Placement;
provided, however, that the registration rights provided to holders of Bridge
Warrants shall be on terms which are pari pasu to the registration rights
provided to purchasers of shares of Series A Preferred Stock.

         (a)      Holders of Registrable Securities, as defined below, shall
         have the demand registration rights described in this Subsection 7(a).

                  (1)      On one occasion only, after the closing of an initial
                           public offering of the Company's Common Stock
                           securities ("INITIAL PUBLIC OFFERING"), in which
                           offering the Company files a registration statement
                           under the Securities Act of 1933 (the "ACT"), upon
                           request by the holders of Registrable Securities who
                           collectively hold or have the right to purchase at
                           least 50% of the Registrable Securities, the Company
                           will promptly take all necessary steps, to register
                           or qualify the sale of Registrable Securities under
                           the Act and such state laws as such holders may
                           reasonably request; provided that (i) such request
                           must be made on or within six (6) years from the date
                           of this Warrant; (ii) the Company is only obligated
                           to register Registrable Securities if the Company is
                           eligible to use registration Form S-3, or a successor
                           form; and (iii) the Registrable Securities included
                           in any such registration has a dollar value of not
                           less than $2,000,000 as of the close of business on
                           the date on which such request was made.

                  (2)      Notwithstanding anything herein to the contrary, the
                           Company may delay filing a registration statement
                           pursuant to Subsection 7(a), and may withhold efforts
                           to cause the registration statement to become
                           effective, for a period of time not exceeding ninety
                           (90) days, if the Company determines in good faith
                           that such registration might adversely affect the
                           Company.

<PAGE>

                  (3)      The Company shall keep effective and maintain any
                           registration, qualification, notification or approval
                           specified in this Subsection 7(a) for such period as
                           may be necessary for the holders of the Registrable
                           Securities to dispose thereof, not to exceed ninety
                           (90) days.

         (b)      Holders of Registrable Securities shall have the incidental
         registration rights described in this Subsection 7(b).

                  (1)      If, at any time beginning on the date six (6) months
                           after the closing of an Initial Public Offering the
                           Company proposes to register the sale of any of its
                           shares of Common Stock under the Act on any
                           registration form which permits resales of securities
                           by security holders of the Company, the Company will
                           give written notice to all registered holders of
                           Registrable Securities, of its intention to do so. On
                           the written request of the registered holders of a
                           majority of the Registrable Securities received by
                           the Company within twenty (20) days after delivery by
                           the Company of any notice, the Company will act to
                           cause all such Registrable Securities, the holders of
                           which shall have requested the registration or
                           qualification thereof, to be included in such
                           registration statement proposed to be filed by the
                           Company.

                  (2)      If any such registration under Subsection 7(b) shall
                           be underwritten in whole or in part, the Company may
                           require that the Registrable Securities requested for
                           inclusion pursuant to Subsection 7(b) be included in
                           the underwriting on the same terms and conditions as
                           the securities otherwise being sold through the
                           underwriters. In the event that, in the good faith
                           judgment of the managing underwriter of such public
                           offering, the inclusion of all or any of the
                           Registrable Securities originally covered by a
                           request for registration would reduce the number of
                           shares to be offered by the Company or interfere with
                           the successful marketing of the shares of Common
                           Stock offered in the underwritten offering, the
                           number of Registrable Securities requested to be
                           included pursuant to this Section 7(b) in the
                           underwritten public offering may be reduced at the
                           discretion of such underwriter. Registrable
                           Securities which are not included in the underwritten
                           public offering shall be withheld from the market for
                           a period, not to exceed ninety (90) days, which the
                           managing underwriter reasonably determines is
                           necessary in order to effect the underwritten public
                           offering.

                  (3)      The Company shall keep effective and maintain any
                           registration, qualification, notification or approval
                           specified in this Subsection 7(b) only for such
                           period as the Company shall be obligated to maintain
                           effectiveness of the underlying registration
                           statement.

                                       5.

<PAGE>

         (c)      For purposes of Section 7, "REGISTRABLE SECURITIES" shall
         collectively mean all Warrant Shares issued or issuable upon exercise
         of Bridge Warrants sold in the Bridge Placement and all shares of the
         Company's Common Stock issued or issuable upon conversion of the
         Company's shares of Series A Preferred Stock; provided, however, that
         Registrable Securities shall not include any of the foregoing shares if
         such shares (i) have been resold in any private or public sale or (ii)
         may be resold pursuant to Rule 144(k) as provided in Subsection 7(h).

         (d)      Any costs and expenses related to any registration pursuant to
         this Section 7 shall be borne by the Company; provided, that the
         persons for whose account the Registrable Securities covered by such
         registration are sold shall bear underwriting commissions applicable to
         their Registrable, fees of their legal counsel and other fees and
         expenses customarily paid by selling shareholders in connection with
         registration rights. If the holders of Registrable Securities are the
         only persons whose shares are included in the registration pursuant to
         Subsection 7(a), such holders shall bear the expense of inclusion of
         audited financial statements in the registration statement which are
         not dated as of the Company's normal fiscal year or are not otherwise
         prepared by the Company for its own business purposes.

         (e)      From time to time the Company shall amend or supplement, at
         the Company's expense, the prospectus used in connection therewith to
         the extent necessary in order to comply with applicable law. If, after
         the registration statement becomes effective, the Company advises the
         holders of registered Registrable Securities that the Company considers
         it appropriate for the registration statement or any prospectus related
         thereto to be amended, the holders of such Registrable Securities shall
         immediately suspend any further sales of their registered Registrable
         Securities until the Company advises them that the registration
         statement or prospectus has been amended.

         (f)      The holder shall furnish in writing to the Company all
         information as may be reasonably requested by the Company or required
         under applicable securities law in connection with any registration of
         Registrable Securities including, but not limited to, the proposed
         method of sale or other disposition of the registered Registrable
         Securities and any compensation payable in connection therewith. The
         holder and the Company shall comply with the provisions of applicable
         securities law in connection with the registration of Registrable
         Securities and the disposition thereof.

         (g)      In connection with any registration statement in which the
         holder's Registrable Securities are included, (i) the holder will
         indemnify the Company, its directors and officers and each person who
         controls the Company, against any losses, claims, damages, liabilities
         and expenses resulting from any untrue or alleged untrue statement of
         material fact contained in the registration statement, prospectus or
         preliminary prospectus or any amendment thereof or supplement thereto
         or any omission or alleged omission of a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading, but only to the extent that such untrue statement or
         omission is contained in or should be contained in any information
         furnished in writing by the holder, and (ii) the

                                       6.

<PAGE>

         Company will indemnify the holder, its directors and officers and each
         person who controls the holder, against losses, which shall be limited
         to the actual amount of the loss incurred on the date of the event
         which invokes the right of indemnification, resulting from any untrue
         or alleged untrue statement of material fact contained in the
         registration statement, prospectus or preliminary prospectus or any
         amendment thereof or supplement thereto or any omission or alleged
         omission of a material fact required to be stated therein or necessary
         to make the statements therein not misleading, except insofar as such
         losses are caused by any untrue statement or omission contained in
         information furnished in writing to the Company by such holder.

         (h)      The Company's obligation to include Registrable Securities in
         a registration under this Section 7 shall terminate on the earlier of:
         (i) the close of business on the date six (6) years from the date of
         original issuance of the Bridge Warrant, and (ii) the date on which, in
         the opinion of legal counsel to the Company, the particular Registrable
         Securities which the holder may request be included in such
         registration statement may be transferred or reissued without
         restriction, in compliance with the provisions of Rule 144(k) under the
         Act, or any successor provision.

         8.)      Compliance with Securities Laws and Other Transfer
Restrictions.

         (a)      The holder of this Bridge Warrant, by acceptance hereof,
         agrees, represents and warrants that this Bridge Warrant and the
         Warrant Shares which may be issued upon exercise hereof are being
         acquired for investment, that the holder has no present intention to
         resell or otherwise dispose of all or any part of this Bridge Warrant
         or any Warrant Shares, and that the holder will not offer, sell or
         otherwise dispose of all or any part of this Bridge Warrant or any
         Warrant Shares except under circumstances which will not result in a
         violation of the Act or applicable state securities laws. The Company
         may condition any transfer, sale, pledge, assignment or other
         disposition on the receipt from the party to whom this Bridge Warrant
         is to be so transferred or to whom Warrant Shares are to be issued or
         so transferred, of any representations and agreements requested by the
         Company in order to permit such issuance or transfer to be made
         pursuant to exemptions from registration under federal and applicable
         state securities laws. Upon exercise of this Bridge Warrant, the holder
         hereof shall, if requested by the Company, confirm in writing holder's
         investment purpose and acceptance of the restrictions on transfer of
         the Warrant Shares, as well as any representations and agreements
         requested by the Company in order to permit the issuance of Warrant
         Shares to be made pursuant to exemptions from registration under
         federal and applicable state securities laws.

         (b)      If the Company conducts an Initial Public Offering of its
         Common Stock or undertakes to file a registration statement pursuant to
         Subsection 7(a), the holder of the Bridge Warrant or any Warrant Shares
         shall not, without the prior written consent of the Company and the
         managing underwriter in such offering: (i) sell, transfer or otherwise
         dispose of, or agree to sell, transfer or otherwise dispose of the
         Bridge Warrant or any of the Warrant Shares; (ii) sell, transfer or
         otherwise dispose of, or agree to sell, transfer or otherwise dispose
         of the Bridge Warrant or any right to purchase any of the Warrant

                                       7.

<PAGE>

         Shares; or (iii) sell or grant, or agree to sell or grant, options,
         rights or warrants with respect to the Bridge Warrant or any of the
         Warrant Shares. Such restrictions shall be effective for a period of
         time equal to the period during which the managing underwriter imposes
         such transfer restrictions on the Company's officers and directors;
         provided, that in no event shall the restricted period applicable to a
         holder of this Bridge Warrant exceed one hundred eighty (180) days
         after effectiveness of the Company's registration statement filed under
         the Act with the Securities and Exchange Commission with respect to
         such offering.

         (c)      In the event the holder of this Bridge Warrant desires to
         transfer this Bridge Warrant, the holder shall provide the Company with
         a Form of Assignment, in the form attached hereto describing the manner
         of such transfer, and an opinion of counsel (reasonably acceptable to
         the Company) that the proposed transfer may be effected without
         registration or qualification under applicable securities laws,
         whereupon such holder shall be entitled to transfer this Bridge Warrant
         in accordance with the notice delivered by such holder to the Company.
         If, in the opinion of the counsel referred to in this Section, the
         proposed transfer or disposition described in the written notice given
         may not be effected without registration or qualification of this
         Bridge Warrant, the Company shall give written notice thereof to the
         holder hereof, and such holder will limit its activities in respect to
         such proposed transfer or disposition as, in the opinion of such
         counsel, are permitted by law. The Company may place one or more
         restrictive legends on the Bridge Warrant or any certificates
         representing the Warrant Shares which set forth the restrictions
         contained herein, and may further place a "stop transfer" restriction
         in the Company's books and records with respect to the Bridge Warrant
         and any Warrant Shares. The restrictions set forth in this Bridge
         Warrant shall be binding upon any holder, donee, assignee or transferee
         of the Bridge Warrant or the Warrant Shares.

         9.)      Subdivision of Bridge Warrant. At the request of the holder of
this Bridge Warrant in connection with a transfer or exercise of a portion of
the Bridge Warrant, upon surrender of such Bridge Warrant for such purpose to
the Company, the Company will issue and exchange therefor warrants of like tenor
and date representing in the aggregate the right to purchase such number of
shares of Common Stock as shall be designated by such holder at the time of such
surrender; provided, however, that the Company's obligations to subdivide
securities under this Section shall be subject to and conditioned upon the
compliance of any such subdivision with applicable securities laws.

         10.)     Loss, Theft, Destruction or Mutilation of Bridge Warrant. Upon
receipt by the Company of evidence reasonably satisfactory to it of the loss,
theft, destruction or mutilation of this Bridge Warrant, and in case of loss,
theft or destruction, of indemnity or security reasonably satisfactory to it,
and upon reimbursement to the Company of all reasonable expenses incidental
thereto, and upon surrender and cancellation of this Bridge Warrant, if
mutilated, the Company will make and deliver a new Bridge Warrant of like tenor
and dates as of such cancellation, in lieu of this Bridge Warrant.

                                       8.

<PAGE>

         11.)     No Limitation on Corporate Action. No provisions of the Bridge
Warrant and no right or option granted or conferred hereunder shall in any way
limit, affect, or abridge the exercise by the Company of any of its corporate
rights or powers to recapitalize, amend its Articles of Incorporation,
reorganize or merge with or into another corporation, or to transfer all or any
part of its property or assets, or the exercise of any other of its corporate
rights and powers.

         12.)     Miscellaneous. This Bridge Warrant shall be governed by the
laws of the state of Minnesota without reference to such state's choice of laws
provisions. The headings in this Bridge Warrant are for purposes of convenience
and reference only, and shall not be deemed to constitute a part hereof. Neither
this Bridge Warrant nor any term hereof may be changed, waived, discharged or
terminated orally but only by an instrument in writing signed by the Company and
the registered holder hereof. All notices and other communications from the
Company to the holder of this Bridge Warrant shall be by certified mail, return
receipt requested, or by overnight delivery service to the address furnished to
the Company in writing by the last holder of this Bridge Warrant who shall have
furnished an address to the Company in writing. Delivery shall be deemed to have
occurred on the date three (3) days after depositing the notice in the U.S. mail
or one (1) day after delivery of such notice to a reputable overnight delivery
service.

                  INTERIM BRIDGE LOAN AND INVESTMENT AGREEMENT

         This Interim Bridge Loan and Investment Agreement (the "AGREEMENT"),
submitted as of the date set forth on the Signature Page, is between Redline
Performance Products, Inc., a Minnesota corporation (the "COMPANY"), and the
undersigned investor (the "INVESTOR").

                                    RECITALS

         The Company is currently attempting to raise capital by selling shares
of its Series A Preferred Stock pursuant to a Confidential Private Placement
Memorandum dated August 1, 2000 (the "MEMORANDUM"). The Company needs interim
capital to fund its operations. The Investor desires to lend funds to the
Company on the terms and conditions set forth in this Agreement. Investors may
lend up to a maximum of $300,000 in principal amount to the Company on terms and
conditions equivalent to those set forth in this Agreement (the "INTERIM LOAN").
The Company has engaged Dougherty & Company LLC (the "AGENT") as its exclusive
agent in connection with the sale of promissory notes and warrants (the "BRIDGE
PLACEMENT"), which was previously completed, and the sale of up to $5,000,000 in
shares of the Company's Series A Preferred Stock (the "SERIES A FINANCING"),
including shares of Series A Preferred Stock issuable upon conversion of the
promissory notes, which is currently in process.

                                    AGREEMENT

         In consideration of the foregoing, the mutual promises set forth
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

1.       Investment. The Investor hereby purchases: (i) an Unsecured
         Subordinated Promissory Note (the "INTERIM NOTE"), in substantially the
         form of EXHIBIT A attached to and incorporated into this Agreement, in
         the principal dollar amount set forth on the Signature Page and (ii) a
         warrant (the "INTERIM WARRANT") in substantially the form of EXHIBIT B
         attached to and incorporated into this Agreement, to purchase one share
         of the Company's $0.01 par value per share common stock (the "COMMON
         STOCK") for every $2.50 in principal amount of the Interim Note (the
         "WARRANT SHARES") and hereby tenders the Investor's check payable to
         "Redline Performance Products, Inc." in the aggregate dollar amount set
         forth on the Signature Page.

         The information contained in this Agreement is only a summary of the
terms and provisions of the Interim Notes and the Interim Warrants, and is
qualified by more detailed information included in the form of Interim Note and
the form of Interim Warrant. If the terms of this Agreement conflict with the
terms of the Interim Note or the Interim Warrant, the terms of the Interim Note
and the Interim Warrant shall control. By execution of this Agreement, the
Investor acknowledges that the Company is relying upon the accuracy and
completeness of the representations contained in this Agreement in complying
with its obligations under applicable securities laws. The Interim Note, the
Interim Warrant and the Warrant Shares are collectively referred to in this
Agreement as the "SECURITIES."

         substantially the form attached hereto as Exhibit A.

<PAGE>

3.       Payment of Principal and Interest. All outstanding principal, and all
         interest accrued on the Interim Notes during the Extension Period, as
         defined below, shall be due and payable by the Company on the earlier
         of: (i) December 31, 2000 and (ii) the date on which the Company
         completes the sale of shares of Series A Preferred Stock which
         generates gross proceeds of at least Two Million Dollars ($2,000,000),
         subject to extension as provided in Section 4. Each of the foregoing
         dates is referred to in this Agreement as a "MATURITY DATE" or
         "MATURITY". The Interim Note shall not accrue interest unless and until
         the Company extends the Maturity Date as provided in Section 4.

4.       Extension of Maturity Date. If the Company is unable to repay the
         Interim Note principal amount on or before the Maturity Date, the
         Company may, at its sole discretion, extend the Maturity Date for a
         period of up to ninety (90) days (the "EXTENSION PERIOD"). If the
         Company elects to extend the Maturity Date, the Company will issue an
         additional Interim Warrant (the "ADDITIONAL INTERIM WARRANT") to the
         holder of the Interim Note on each of the 15th, 45th and 75th day of
         the Extension Period if the principal amount of the Interim Note and
         interest thereon has not been paid as of each such date. The number of
         shares of Common Stock subject to each Additional Interim Warrant shall
         be equal to 25% of the number of shares of Common Stock subject to the
         original Interim Warrant issued to the Investor. During the Extension
         Period, the Interim Note shall accrue interest at the rate of fifteen
         percent (15%) per annum on any unpaid principal amount.

5.       Subordination. The payment of principal and interest under the Interim
         Note is not secured by any collateral and is subordinated to the
         payment by the Company of "SENIOR INDEBTEDNESS" as defined in the
         Interim Note. Payment of principal or interest may not be made on the
         Interim Note if the Company is in default, or if the making of any
         payment would result in a default, with respect to the payment of
         amounts of any Senior Indebtedness.

6.       Default. The Company shall be in default under this Agreement and under
         the Interim Note upon the happening after the date of this Agreement of
         any nonpayment, when due, of any amount payable to the holder under the
         Interim Note. In the event of a default: (a) the holders of Interim
         Notes shall have the right, at their option and not subject to demand
         or notice, to declare all or any part of the Interim Notes immediately
         due and payable, and (b) the holders of Interim Notes may exercise, in
         addition to the rights and remedies granted in this Agreement, all of
         the rights and remedies of a holder under the Interim Note and under
         applicable law.

7.       Interim Warrant. In conjunction with the purchase of a Interim Note by
         the Investor, the Company will issue to the Investor a Interim Warrant
         in substantially the form attached to this Agreement as Exhibit B. The
         Interim Warrant will entitle the Investor to purchase one share of
         Common Stock for every $2.50 in principal amount of the Interim Note.
         The Interim Warrant will have an exercise price of $1.25 per share,
         will be exercisable one hundred eighty (180) days after issuance and
         will expire five (5) years from the date of issuance.

8.       Reservation of Shares of Common Stock. The Company shall, during the
         time that the Interim Warrant remains outstanding, reserve and keep
         available from its authorized but unissued shares of Common Stock, a
         sufficient number of shares to issue the Warrant Shares.

9.       Transfer Restrictions. The Securities shall be subject to certain
         restrictions on transfer as identified in this Agreement, the Interim
         Note and the Interim Warrant.

IF YOU HAVE NOT INITIALED ANY OF THE FOREGOING, YOU ARE NOT AN ACCREDITED
INVESTOR AND CANNOT PURCHASE ANY SECURITIES.

         IF YOU HAVE INITIALED ANY OF THE FOREGOING, PLEASE PROCEED.

                RMF PR (iii) Entities. A REPRESENTATIVE OF AN ENTITY INVESTOR
                       MUST INITIAL HERE If the Investor is an entity, the
                       individual(s) signing on behalf of the Investor and the
                       Investor, jointly and severally, agree and certify that
                       this Agreement has been duly authorized by all necessary
                       action on the part of the Investor, has been duly
                       executed by an authorized representative of the Investor,
                       and is a legal, valid, and binding obligation of the
                       Investor enforceable in accordance with its terms.

13.      Investment Purpose in Acquiring the Securities. The Investor and the
         Company acknowledge that the Securities have not been registered under
         the Act or applicable state securities laws and that the Securities
         will be issued to the Investor in reliance on exemptions from the
         registration requirements of the Act and applicable state securities
         laws and in reliance on the Investor's and the Company's
         representations and agreements contained herein. The Investor is
         acquiring the Securities for the account of the Investor for investment
         purposes only and not with a view to their resale or distribution. The
         Investor has no present intention to divide his, her or its
         participation with others or to resell or otherwise dispose of all or
         any part of the Securities. In making these representations, the
         Investor understands that, in the view of the Commission, exemption of
         the Securities from the registration requirements of the Act would not
         be available if, notwithstanding the representations of the Investor,
         the Investor has in mind merely acquiring the Securities for resale
         upon the occurrence or non-occurrence of some predetermined event.

14.      Compliance with Securities Act. The Investor agrees that if the
         Securities or any part thereof are sold or distributed in the future,
         the Investor shall sell or distribute them pursuant to the requirements
         of the Act and applicable state securities laws. The Investor agrees
         that the Investor will not transfer any part of the Securities without:
         (i) obtaining a "no action" letter from the Commission and applicable
         state securities commissions; (ii) obtaining an opinion of counsel
         satisfactory in form and substance to the Company to the effect that
         such transfer is exempt from the registration requirements under the
         Act and applicable state securities laws; or (iii) registration.

15.      Restriction on Transfer After a Public Offering. The Investor
         understands that the Company at a future date may file a registration
         or offering statement (the "REGISTRATION STATEMENT") with the
         Commission to facilitate a public offering of its securities. The
         Investor agrees, for the benefit of the Company, that should such an
         initial public offering be made and should the managing underwriter of
         such offering require, the Investor will not, without the prior written
         consent of the Company and such underwriter, during the "Lockup Period"
         as defined herein: (i) sell, transfer or otherwise dispose of, or agree
         to sell, transfer or otherwise dispose of any of the Securities
         beneficially owned by the Investor during the Lockup Period; (ii) sell,
         transfer or otherwise dispose of, or agree to sell, transfer or
         otherwise dispose of any options, rights or warrants to purchase any of
         the Securities beneficially owned by the Investor during the Lockup
         Period; or (iii) sell or grant, or agree to sell or grant, options,
         rights or warrants with respect to any of the Securities. The foregoing
         does not prohibit gifts to donees or transfers by will or the laws of
         descent to heirs or beneficiaries provided that such donees, heirs and
         beneficiaries shall be bound by the restrictions set forth herein. The
         term "LOCKUP PERIOD" shall mean the lesser of (x) 180 days and (y) the
         period during which Company officers and directors are restricted by
         the managing

                                       7.

<PAGE>

         underwriter from effecting any sales or transfers of the Company's
         common stock. The Lockup Period shall commence on the effective date of
         the Registration Statement.

16.      Restrictive Legend. The Investor agrees that the Company may place one
         or more restrictive legends on any certificates evidencing the
         Securities, including the Conversion Shares, containing substantially
         the following language:

         The securities represented by this certificate have not been registered
         under the Securities Act of 1933, as amended, have not been registered
         under any state securities law, and are subject to a subscription and
         investment representation agreement. They may not be sold, offered for
         sale, transferred, assigned, pledged or otherwise distributed for value
         unless there is an effective registration under the Securities Act of
         1933, as amended, and under the applicable state securities laws, or
         the Company receives an opinion of counsel acceptable to the Company
         stating that such transaction is exempt from registration and
         prospectus delivery requirements of the Securities Act of 1933, as
         amended, and under the applicable state securities laws.

         Sale or other transfer of these securities is further restricted for up
         to 180 days following an initial public offering of securities of the
         Company by the terms of a Subscription Agreement, a copy of which is
         available for inspection at the offices of the Company.

17.      Stop Transfer Order. The Investor agrees that the Company may place a
         stop transfer order with its registrar and transfer agent (if any)
         covering all Securities.

18.      Knowledge of Restrictions upon Transfer of the Securities. The Investor
         understands that the Securities are not freely transferable and may in
         fact be prohibited from sale for an extended period of time and that,
         as a consequence thereof, the Investor must bear the economic risk of
         an investment in the Securities for an indefinite period of time and
         may have extremely limited opportunities to dispose of the Securities.
         The Investor realizes that there will likely be no market for the
         Securities, and that there are significant restrictions on the
         transferability thereof.

19.      Lack of Availability of Rule 144 Under the Act. The Investor
         understands and acknowledges that the Company has no obligation to
         undertake or complete a public offering of its securities, that even if
         a public offering is undertaken and successfully completed, the
         Securities subscribed for hereby will remain subject to the
         restrictions on transferability described herein, and that even if a
         public offering is undertaken and completed, the Investor may never be
         able to sell its Securities pursuant to Rule 144 under the Act.

         The Investor further understands and acknowledges that the Company
currently does not file periodic reports with the Commission pursuant to the
requirements of Sections 13 or 15(d) of the Securities Exchange Act of 1934, and
may not be obligated to file such reports at any time in the future. The
Investor also understands that the Company has not agreed to supply such other
information as would be required to enable routine sales of the Securities to be
made under the provisions of certain rules respecting "restricted securities,"
including Rule 144 promulgated under the Act by the Commission. Thus, the
Investor has been informed that the Company is not obligated to make publicly
available or to provide the Investor with the information required by Rule 144.

         by initialing the appropriate response):

$100,000.00                                                     November 1, 2000

         FOR VALUE RECEIVED, the undersigned, Redline Performance Products,
Inc., organized and existing under the laws of the State of Minnesota, whose
mailing address is 2520 Fortune Way, Vista, California 92083, and its successors
and assigns (the "BORROWER"), for value received, hereby unconditionally
promises to pay to the order of Industricorp & Co., Inc. FBO Twin City
Carpenters Pension Fund - Acct #156000091, having a mailing address of c/o Union
Bank & Trust, Trust Dept - Suite 508, 312 Central Avenue SE, Minneapolis,
Minnesota 55414, and its successors and assigns (the "LENDER"), at such place as
may be designated from time to time by the Lender, the principal sum of One
Hundred Thousand and 00/100 Dollars ($100,000.00), at or before 5:00 p.m. Vista,
California time on December 31, 2000, or earlier as provided herein ("MATURITY
DATE"). This promissory note (the "INTERIM NOTE") is being issued in connection
with a placement of Interim Notes and warrants to purchase shares of the
Borrower's common stock (the "INTERIM WARRANT") being conducted by the Company
to raise up to $300,000 pursuant to the terms of an Interim Bridge Loan and
Investment Agreement. This Interim Note and the Holder hereof are entitled to
all the benefits provided for in the Interim Bridge Loan and Investment
Agreement, or which are referred to therein, pursuant to which this indebtedness
was incurred and is to be repaid. The provisions of the Interim Bridge Loan and
Investment Agreement are incorporated herein by reference with the same force
and effect as if fully set forth herein.

1.       Payment. Subject to extension as provided in this Section 1, all
         outstanding principal, and any interest accrued on the Interim Note
         during the Extension Period, as defined herein, shall be due and
         payable on the earlier of: (i) December 31, 2000 and (ii) the date on
         which the Borrower generates gross proceeds of at least $2,000,000 (the
         "MINIMUM AMOUNT") from the sale of shares of the Borrower's Series A
         Preferred Stock in the a proposed placement of Series A Preferred Stock
         intended to raise the Minimum Amount and up to $5,000,000 (the "SERIES
         A FINANCING"), unless all principal hereunder shall have been paid.
         Each of the foregoing dates is referred to in this Interim Note as the
         "MATURITY DATE" or "MATURITY". All payments under this Section shall be
         made by check mailed by the Borrower to the address of the Lender set
         forth above. If the Borrower is unable to repay the Interim Note
         principal on or

<PAGE>

         before the Maturity Date, the Company may, in its sole discretion,
         extend the Maturity Date for a period of up to ninety (90) days (the
         "EXTENSION PERIOD"). If the Borrower elects to extend the Maturity
         Date, the Company shall issue an additional Interim Warrant (the
         "ADDITIONAL INTERIM WARRANT") to the holder of the Interim Note on each
         of the 15th, 45th and 75th day of the Extension Period if the Interim
         Loan principal and interest has not been paid as of such dates. The
         number of shares of Common Stock subject to each Additional Interim
         Warrant shall be equal to 25% of the number of shares of Common Stock
         subject to the original Interim Warrant issued to the Investor. During
         the Extension Period, the Interim Note shall accrue interest at the
         rate of fifteen percent (15%) per annum. During the Extension Period
         interest on the unpaid principal balance of this Interim Note shall be
         calculated on the basis of a 360-day year comprised of twelve 30-day
         months.

2.       Subordination. The term "SENIOR INDEBTEDNESS" shall mean all principal
         of (and premium of, if any) and unpaid interest on all indebtedness of
         the Borrower, and with respect to which the Borrower is a guarantor
         (but excluding indebtedness guaranteed solely for the benefit of
         officers, directors, employees or consultants of the Borrower), and
         except as provided to the contrary herein, regardless of whether
         incurred on, before or after the date of this Interim Note: (i) for
         money borrowed from any bank, insurance company, or other lending
         institution regularly engaged in the business of lending money, whether
         or not secured; (ii) for amounts owed to TMAG Industries, Inc. as of
         the date of this Interim Note and (iii) in connection with any
         deferral, renewal or extension of any indebtedness described in (i) or
         (ii) above or any debentures, notes, or other evidence of the
         Borrower's indebtedness issued in exchange for indebtedness described
         in (i) or (ii) above. The Borrower covenants and agrees and the Lender,
         by acceptance hereof, covenants, expressly for the benefit of the
         present and future holders of Senior Indebtedness, that the payment of
         the principal and the interest on this Interim Note is expressly
         subordinated in right of payment to the payment in full of all
         principal and interest of Senior Indebtedness of the Borrower.
         Notwithstanding the foregoing, payment of principal or interest may be
         made hereunder unless the Company is in default, or if the making of
         any payment hereunder would result in a default, with respect to the
         payment of amounts of any Senior Indebtedness.

3.       Compliance with Securities Laws and Other Transfer Restrictions.

         a.      The holder of this Interim Note, by acceptance hereof, agrees,
                 represents and warrants that this Interim Note are being
                 acquired for investment, that the holder has no present
                 intention to resell or otherwise dispose of all or any part of
                 this Interim Note, and that the holder will not offer, sell or
                 otherwise dispose of all or any part of this Interim Note
                 except under circumstances which will not result in a violation
                 of the Act or applicable state securities laws. The Borrower
                 may condition any transfer, sale, pledge, assignment or other
                 disposition on the receipt, from the party to whom this Interim
                 Note is to be so transferred, of any representations and
                 agreements requested by the Borrower in order to permit such
                 issuance or transfer to be made pursuant to exemptions from
                 registration under federal and applicable state securities
                 laws.

         b.      If the Borrower conducts an Initial Public Offering of its
                 Common Stock, the holder of the Interim Note shall not, without
                 the prior written consent of the Borrower and the managing
                 underwriter in such offering: (i) sell, transfer or otherwise
                 dispose of, or agree to sell, transfer or otherwise dispose of
                 the Interim Note; (ii) sell, transfer or otherwise dispose of,
                 or agree to sell, transfer or otherwise dispose of any right to
                 purchase the Interim Note; or (iii) sell or grant, or agree to
                 sell or grant, options, rights or warrants with respect to the
                 Interim Note. Such restrictions shall be effective for a period
                 of time equal to the period during which the managing

                                       2.

<PAGE>

                 underwriter imposes such transfer restrictions on the
                 Borrower's officers and directors; provided, that in no event
                 shall the restricted period applicable to a holder of this
                 Interim Note exceed one hundred twenty (180) days after
                 effectiveness of the Borrower's registration statement filed
                 under the Act with the Securities and Exchange Commission with
                 respect to such offering.

         c.      In the event the holder of this Interim Note desires to
                 transfer this Interim Note, the holder shall provide the
                 Borrower with a Form of Assignment, in the form attached hereto
                 describing the manner of such transfer, and an opinion of
                 counsel (reasonably acceptable to the Borrower) that the
                 proposed transfer may be effected without registration or
                 qualification under applicable securities laws, whereupon such
                 holder shall be entitled to transfer this Interim Note in
                 accordance with the notice delivered by such holder to the
                 Borrower. If, in the opinion of the counsel referred to in this
                 Subsection, the proposed transfer or disposition described in
                 the written notice given may not be effected without
                 registration or qualification of this Interim Note, the
                 Borrower shall give written notice thereof to the holder
                 hereof, and such holder will limit its activities in respect to
                 such proposed transfer or disposition as, in the opinion of
                 such counsel, are permitted by law.

         d.      The Borrower may place one or more restrictive legends on the
                 Interim Note which set forth the restrictions contained herein,
                 and may further place a "stop transfer" restriction in the
                 Borrower's books and records with respect to the Interim Note.
                 The restrictions set forth in this Interim Note shall be
                 binding upon any holder, donee, assignee or transferee of the
                 Interim Note.

4.       Rights as Shareholder. The Holder of this Interim Note shall have no
         rights as a shareholder of the Borrower.

5.       Negative Covenant.

         (a)     The Company shall not transfer, sell, convey or otherwise
         encumber in any manner (other than to grant a license for
         marketing purposes to use one or more of the tradenames for which the
         Company has filed applications for trademark protection) the
         Technology Assets without the prior written consent of the holders of
         two-thirds of the principal dollar amount of the outstanding Interim
         Notes, which dollar amount shall exclude any accrued interest on such
         outstanding Interim Notes.  Such consent shall not be unreasonably
         withheld. The negative covenant described in this Subsection 5(a) is
         referred to herein as the "NEGATIVE COVENANT." The intended effect of
         the Negative Covenant is to limit the Company's ability to transfer
         or encumber the Technology Assets. The Negative Covenant does not,
         and is not intended to, grant holders of Interim Notes a security or
         any other interest in the Technology Assets.

         (b)     "TECHNOLOGY ASSETS" shall mean: (i) Patent Application entitled
         "Snowmobile Suspension," Patent Serial No. 09/502,280; (ii) Patent
         Application entitled "Snowmobile," Patent Serial No. 09/268,264; (iii)
         "Redline Snowmobiles" Trademark Application, U.S. Serial No. 75-438,530
         - Filed February 23, 1998; (iv) "Rebellion" Trademark Application, U.S.
         Serial No. 75-807,788 - Filed September 24, 1999; (v) "954 Revolution"
         Trademark Application, U.S. Serial No. 75-808,530 - Filed September 24,
         1999; (vi) "Revolt" Trademark Application, U.S. Serial No. 75-807,847 -
         Filed September 24, 1999; and (vii) any resultant patent or registered
         trademark from (i) through (vi) above.

         (c)     At such time as the Company determines that a transfer, sale,
         conveyance or other encumbrance of the Technology Assets is necessary
         or appropriate, the Company shall give each holder of record of

                                       3.

<PAGE>

         outstanding Interim Notes written notice ("NOTICE") of the Company's
         intention to undertake such a transfer, sale, conveyance or other
         encumbrance. The Notice shall include a general description of the
         terms of the proposed transaction and a consent form which the holder
         of the Interim Note may use to indicate such holder's consent to the
         proposed transaction. If the holders of two-thirds of the principal
         dollar amount of outstanding Interim Notes (excluding accrued interest
         thereon) do not consent to the proposed transaction within 30 days of
         delivery of the Notice, the Company shall not undertake the proposed
         transaction described in the Notice. Delivery of the Notice shall be to
         the most recent address included in the Company's records of holders of
         Interim Notes.

         (d) The Negative Covenant shall terminate with respect to each
         outstanding Interim Note upon the earlier of: (i) the payment of the
         principal amount and accrued interest on such outstanding Interim Note;
         (ii) the conversion of such outstanding Interim Note into shares of the
         Company's capital stock; and (iii) the written agreement of the holders
         of all of the outstanding Interim Notes.

6.       Miscellaneous Provisions.

         a.      No amendment hereunder shall be effective unless in writing
                 signed by the Borrower and the Lender and no waiver hereunder
                 shall be effective unless in writing, signed by the party to be
                 charged. Neither the failure on the part of the Lender in
                 exercising any right or remedy, nor any single or partial
                 exercise of any other right or remedy, shall operate as a
                 waiver. The acceptance by the Lender of any payment hereunder
                 which is less than payment in full of all amounts due and
                 payable at the time of such payment shall not constitute a
                 waiver of the right to exercise any of the options hereunder at
                 that time or at any subsequent time.

         b.      The Borrower hereby: (i) waives diligence, presentment, demand
                 for payment, notice of dishonor, notice of non-payment,
                 protest, notice of protest, and any and all other demands in
                 connection with the delivery, acceptance, performance, default
                 or enforcement of this Interim Note, and (ii) except as
                 provided in Section 1 of this Interim Note, agrees that the
                 Lender has, subject to the prior written request or approval of
                 the Borrower, the right (but not the obligation) to grant any
                 extension of time for payment of any indebtedness evidenced by
                 this Interim Note.

         c.      The terms and provisions hereof shall inure to the benefit of,
                 and be binding upon, the respective successors and assigns of
                 the Borrower and Lender. This Interim Note shall be governed by
                 and construed and enforced in accordance with the laws of the
                 State of Minnesota without giving effect to such state's choice
                 of law principles.

         d.      No recourse for the payment of the principal of or any interest
                 on this Interim Note, or for any claim based hereon or
                 otherwise in respect hereof, and no recourse under or upon any
                 obligation, covenant or agreement of the Borrower in any
                 Interim Note, or because of the creation of any indebtedness
                 represented thereby, shall be had against any incorporator,
                 shareholder, officer or director as such, past, present or
                 future, of the Borrower or of any successor corporation either
                 directly or through the Borrower or any successor corporation,
                 whether by virtue of any constitution, statute or rule of law
                 or by the enforcement of any assessment or penalty or
                 otherwise, all such liability being, by the acceptance hereof
                 and as part of the consideration for the issue hereof,
                 expressly waived and released.

                                       4.

         e.      The Borrower covenants that during the period this Interim Note
                 is convertible, the Borrower will reserve from its authorized
                 and unissued shares of common stock a sufficient number of
                 shares to provide for the issuance of Conversion Shares upon
                 the conversion of this Interim Note, and shares of common stock
                 upon conversion of the Conversion Shares. The Borrower further
                 covenants that all Conversion Shares that may be issued upon
                 the conversion of this Interim Note will, upon payment and
                 issuance, be duly authorized and issued, fully paid and
                 nonassessable shares of the Borrower's common stock.

         f.      Upon receipt by the Borrower of evidence reasonably
                 satisfactory to it of the loss, theft, destruction or
                 mutilation of this Interim Note, and in case of loss, theft or
                 destruction, of indemnity or security reasonably satisfactory
                 to it, and upon reimbursement to the Borrower of all reasonable
                 expenses incidental thereto, and upon surrender and
                 cancellation of this Interim Note, if mutilated, the Borrower
                 will make and deliver a new Interim Note of like tenor and
                 dates as of such cancellation, in lieu of this Interim Note.

         g.      This Interim Note has been issued pursuant to and is subject to
                 the terms and provisions of that certain Interim Bridge Loan
                 and Investment Agreement of even date herewith between the
                 Borrower and the Lender, the terms and provisions of which are
                 incorporated herein by reference with the same force and effect
                 as if fully set forth herein. To the extent the terms of the
                 Interim Note and the Interim Bridge Loan and Investment
                 Agreement are inconsistent, the terms of this Interim Note
                 shall control.

         h.      All notices and other communications shall be by certified
                 mail, return receipt requested, or by overnight delivery
                 service to the address furnished to the Borrower in writing by
                 the last holder of this Interim Note who shall have furnished
                 an address to the Borrower in writing. Delivery shall be deemed
                 to have occurred on the date three (3) days after depositing
                 the notice in the U.S. mail or one (1) day after delivery of
                 such notice to a reputable overnight delivery service.

         IN WITNESS WHEREOF, the Borrower has caused this Interim Note to be
executed by its authorized representative, who certifies that he has all
necessary authority on behalf of the Borrower to execute this Interim Note and
bind the Borrower to the terms hereof.

                               WARRANT TO PURCHASE
                             SHARES OF COMMON STOCK
                                       OF
                       REDLINE PERFORMANCE PRODUCTS, INC.

Warrant No. I-1                                                  Shares: 40,000

         THIS CERTIFIES that, subject to the terms and conditions herein set
forth, Industricorp & Co., Inc. FBO Twin City Carpenters Pension Fund - Acct
#156000091 or registered assigns, is entitled to purchase from REDLINE
PERFORMANCE PRODUCTS, INC., a Minnesota corporation (the "COMPANY"), at any time
after one hundred eighty (180) days from the date of original issuance of this
warrant (the "INTERIM WARRANT") and prior to the time and date set forth above,
forty thousand (40,000) fully paid and nonassessable shares of $0.01 par value
per share common stock of the Company (such class of shares being referred to as
the "COMMON STOCK," and such shares of Common Stock which may be acquired upon
exercise of this Interim Warrant being referred to as the "WARRANT SHARES").
This Interim Warrant is being issued in connection with a placement (the
"Interim PLACEMENT") of promissory notes ("INTERIM NOTES") and Interim Warrants
being conducted by the Company to raise up $300,000 and pursuant to the terms of
a Interim Bridge Loan and Investment Agreement. This Interim Warrant and the
Holder hereof are entitled to all the benefits provided for in the Interim
Bridge Loan and Investment Agreement, or which are referred to therein to which
this indebtedness was incurred and is to be repaid. The provisions of the
Interim Bridge Loan and Investment Agreement are incorporated herein by
reference with the same force and effect as if fully set forth herein.

         This Interim Warrant is subject to the following terms and conditions:

1.       Purchase Price. Subject to adjustment as hereinafter provided, the
         purchase price of each Warrant Share shall be One and 25/100 Dollars
         ($1.25). The purchase price of one Warrant Share is referred to herein
         as the "INTERIM WARRANT PRICE."

2.       Adjustment of Interim Warrant Price and Number of Warrant Shares. The
         provisions in this Interim Warrant relating to the Interim Warrant
         Price and the number of Warrant Shares to be issued upon exercise of
         this Interim Warrant shall be subject to adjustment from time to time
         as hereinafter provided.

<PAGE>

         a.      Upon each adjustment of the Interim Warrant Price, the Holder
                 of this Interim Warrant shall thereafter be entitled to
                 purchase, at the Interim Warrant Price resulting from such
                 adjustment, the number of shares of Common Stock obtained by
                 multiplying the Interim Warrant Price in effect immediately
                 prior to such adjustment by the number of shares of Common
                 Stock purchasable hereto immediately prior to such adjustment
                 and dividing the product thereof by the Interim Warrant Price
                 resulting from such adjustment.

         b.      In case the Company shall at any time subdivide its outstanding
                 Common Stock into a greater number of shares or declare a
                 dividend payable in Common Stock, the Interim Warrant Price in
                 effect immediately prior to such subdivision shall be
                 proportionately reduced and the number of shares of Common
                 Stock purchasable pursuant to this Interim Warrant shall be
                 proportionately increased, and conversely, in case the
                 Company's outstanding Common Stock shall be combined into a
                 smaller number of shares, the Interim Warrant Price in effect
                 immediately prior to such combination shall be proportionately
                 increased and the number of shares of Common Stock purchasable
                 upon the exercise of this Interim Warrant shall be
                 proportionately reduced.

         c.      If any capital reorganization or reclassification of the
                 capital stock of the Company, or consolidation or merger of the
                 Company with another corporation, or the sale of all or
                 substantially all of its assets to another corporation shall be
                 effected in such a way that holders of Common Stock shall be
                 entitled to receive stock, securities or assets ("SUBSTITUTED
                 PROPERTY") with respect to or in exchange for such Common
                 Stock, then, as a condition of such reorganization,
                 reclassification, consolidation, merger or sale, the Holder
                 shall have the right to purchase and receive upon the basis and
                 upon the terms and conditions specified in this Interim
                 Warrant, and in lieu of the Common Stock of the Company
                 immediately theretofore purchasable and receivable upon the
                 exercise of the rights represented hereby, such Substituted
                 Property as would have been issued or delivered to the Holder
                 if it had exercised this Interim Warrant and had received upon
                 exercise of this Interim Warrant the Common Stock prior to such
                 reorganization, reclassification, consolidation, merger, or
                 sale. The Company shall not effect any such consolidation,
                 merger, or sale, unless prior to the consummation thereof the
                 successor corporation (if other than the Company) resulting
                 from such consolidation or merger or the corporation purchasing
                 such assets shall assume the obligation to deliver to the
                 Holder such Substituted Property as, in accordance with the
                 foregoing provisions, the Holder may be entitled to purchase.

         d.      If the Company takes any other action, or if any other event
                 occurs which does not come within the scope of the provisions
                 of Sections 2(b) or 2(c), but which should, in the Company's
                 reasonable judgment, result in an adjustment in the Interim
                 Warrant Price and/or the number of shares subject to the
                 Interim Warrant in order to fairly protect the purchase rights
                 of the Holder, an appropriate adjustment in such purchase
                 rights shall be made by the Company.

         e.      Upon any adjustment of the Interim Warrant Price or the number
                 of shares issuable upon of this Interim Warrant, the Company
                 shall give written notice thereof, by first-class mail,
                 postage prepaid, addressed to the Holder at the address of the
                 Holder as shown on the books of the Company, which notice
                 shall state the Interim Warrant Price resulting from such
                 adjustment and the increase or decrease, if any, in the number
                 of shares purchasable at such price upon the exercise of this
                 Interim Warrant, setting forth in reasonable detail the method
                 of calculation and the facts upon which such calculation is
                 based.

                                       2.

3.       No Fractional Shares. No fractional shares will be issued in connection
         with any exercise of this Interim Warrant. In lieu of any fractional
         share which would otherwise be issuable, the Company shall pay cash
         equal to the product of such fraction multiplied by the fair market
         value, as determined by the Company's officers, of one share of Common
         Stock on the date of exercise.

4.       No Shareholder Rights. This Interim Warrant shall not entitle its
         holder to vote, receive dividends or exercise any of the rights of a
         shareholder of the Company prior to exercise of this Interim Warrant.

5.       Covenants of the Company. The Company covenants that during the period
         this Interim Warrant is exercisable, the Company will reserve from its
         authorized and unissued shares of Common Stock a sufficient number of
         shares of Common Stock to provide for the issuance of Warrant Shares
         upon the exercise of this Interim Warrant. The Company further
         covenants that all Warrant Shares that may be issued upon the exercise
         of this Interim Warrant will, upon payment and issuance, be duly
         authorized and issued, fully paid and nonassessable shares of Common
         Stock.

6.       Exercise of Interim Warrant. This Interim Warrant may be exercised by
         the registered holder, in whole or in part, by the surrender of this
         Interim Warrant at the principal office of the Company, together with
         the Exercise Form attached hereto duly executed, accompanied by payment
         in full of the amount of the aggregate Interim Warrant Price in cash,
         cashier's check or bank draft. Upon partial exercise hereof, a new
         warrant or warrants containing the same date and provisions as this
         Interim Warrant shall be issued by the Company to the registered holder
         for the number of Warrant Shares with respect to which this Interim
         Warrant shall not have been exercised. For each partial exercise the
         holder shall purchase a minimum of five thousand (5,000) Warrant
         Shares, or, if the number of Warrant Shares available for exercise
         under the Interim Warrant is less than such minimum number, the balance
         of the Warrant Shares available for exercise under the Interim Warrant.
         A Interim Warrant shall be deemed to have been exercised immediately
         prior to the close of business on the date the Company is in receipt of
         this Interim Warrant, a completed Exercise Form, all documents the
         Company may reasonably request from the holder for the purpose of
         complying with applicable securities and other laws, and payment for
         the number of Warrant Shares being acquired upon exercise of this
         Interim Warrant. The holder entitled to receive the Warrant Shares
         issuable upon such exercise shall be treated for all purposes as the
         holder of record of such Warrant Shares as of the close of business on
         such date. After such date, the Company shall issue and deliver to the
         holder or holders entitled to receive the same, a certificate or
         certificates for the number of full Warrant Shares issuable upon such
         exercise, together with cash in lieu of any fraction of a share, as
         provided above.

7.       Registration of Warrant Shares. The rights of the holder of this
         Interim Warrant to include Warrant Shares in a registered offering of
         securities conducted by the Company are set forth in this Section 7.
         Upon any closing of the Series A Placement, as such placement is
         described in the Interim Bridge Loan and Investment Agreement, the
         registration rights set forth in this Section 7 shall be superseded and
         replaced by the registration rights provided to purchasers of shares of
         Series A Preferred Stock in the Series A Placement; provided, however,
         that the registration rights provided to holders of Interim Warrants
         shall be on terms which are pari pasu to the registration rights
         provided to purchasers of shares of Series A Preferred Stock.

         a.      Holders of Registrable Securities, as defined below, shall have
                 the demand registration rights described in this Subsection
                 7(a).

                                       3.

                 (1)       On one occasion only, after the closing of an initial
                           public offering of the Company's Common Stock
                           securities ("INITIAL PUBLIC OFFERING"), in which
                           offering the Company files a registration statement
                           under the Securities Act of 1933 (the "ACT"), upon
                           request by the holders of Registrable Securities who
                           collectively hold or have the right to purchase at
                           least 50% of the Registrable Securities, the Company
                           will promptly take all necessary steps, to register
                           or qualify the sale of Registrable Securities under
                           the Act and such state laws as such holders may
                           reasonably request; provided that (i) such request
                           must be made on or within six (6) years from the date
                           of this Warrant; (ii) the Company is only obligated
                           to register Registrable Securities if the Company is
                           eligible to use registration Form S-3, or a successor
                           form; and (iii) the Registrable Securities included
                           in any such registration has a dollar value of not
                           less than $2,000,000 as of the close of business on
                           the date on which such request was made.

                 (2)       Notwithstanding anything herein to the contrary, the
                           Company may delay filing a registration statement
                           pursuant to Subsection 7(a), and may withhold efforts
                           to cause the registration statement to become
                           effective, for a period of time not exceeding ninety
                           (90) days, if the Company determines in good faith
                           that such registration might adversely affect the
                           Company.

                 (3)       The Company shall keep effective and maintain any
                           registration, qualification, notification or approval
                           specified in this Subsection 7(a) for such period as
                           may be necessary for the holders of the Registrable
                           Securities to dispose thereof, not to exceed ninety
                           (90) days.

         b.      Holders of Registrable Securities shall have the incidental
                 registration rights described in this Subsection 7(b).

                 (1)       If, at any time beginning on the date six (6) months
                           after the closing of an Initial Public Offering the
                           Company proposes to register the sale of any of its
                           shares of Common Stock under the Act on any
                           registration form which permits resales of securities
                           by security holders of the Company, the Company will
                           give written notice to all registered holders of
                           Registrable Securities, of its intention to do so. On
                           the written request of the registered holders of a
                           majority of the Registrable Securities received by
                           the Company within twenty (20) days after delivery by
                           the Company of any notice, the Company will act to
                           cause all such Registrable Securities, the holders of
                           which shall have requested the registration or
                           qualification thereof, to be included in such
                           registration statement proposed to be filed by the
                           Company.

                 (2)       If any such registration under Subsection 7(b) shall
                           be underwritten in whole or in part, the Company may
                           require that the Registrable Securities requested for
                           inclusion pursuant to Subsection 7(b) be included in
                           the underwriting on the same terms and conditions as
                           the securities otherwise being sold through the
                           underwriters. In the event that, in the good faith
                           judgment of the managing underwriter of such public
                           offering, the inclusion of all or any of the
                           Registrable Securities originally covered by a
                           request for registration would reduce the number of
                           shares to be offered by the Company or interfere with
                           the successful marketing of the shares of Common
                           Stock offered in the underwritten offering, the
                           number of Registrable Securities requested to be
                           included pursuant to this Section

                                       4.

<PAGE>

                           7(b) in the underwritten public offering may be
                           reduced at the discretion of such underwriter.
                           Registrable Securities which are not included in the
                           underwritten public offering shall be withheld from
                           the market for a period, not to exceed ninety (90)
                           days, which the managing underwriter reasonably
                           determines is necessary in order to effect the
                           underwritten public offering.

                 (3)       The Company shall keep effective and maintain any
                           registration, qualification, notification or approval
                           specified in this Subsection 7(b) only for such
                           period as the Company shall be obligated to maintain
                           effectiveness of the underlying registration
                           statement.

         c.      For purposes of Section 7, "REGISTRABLE SECURITIES" shall
                 collectively mean all Warrant Shares issued or issuable upon
                 exercise of Interim Warrants sold in the Interim Placement and
                 all shares of the Company's Common Stock issued or issuable
                 upon conversion of the Company's shares of Series A Preferred
                 Stock; provided, however, that Registrable Securities shall not
                 include any of the foregoing shares if such shares (i) have
                 been resold in any private or public sale or (ii) may be resold
                 pursuant to Rule 144(k) as provided in Subsection 7(h).

         d.      Any costs and expenses related to any registration pursuant to
                 this Section 7 shall be borne by the Company; provided, that
                 the persons for whose account the Registrable Securities
                 covered by such registration are sold shall bear underwriting
                 commissions applicable to their Registrable, fees of their
                 legal counsel and other fees and expenses customarily paid by
                 selling shareholders in connection with registration rights. If
                 the holders of Registrable Securities are the only persons
                 whose shares are included in the registration pursuant to
                 Subsection 7(a), such holders shall bear the expense of
                 inclusion of audited financial statements in the registration
                 statement which are not dated as of the Company's normal fiscal
                 year or are not otherwise prepared by the Company for its own
                 business purposes.

         e.      From time to time the Company shall amend or supplement, at the
                 Company's expense, the prospectus used in connection therewith
                 to the extent necessary in order to comply with applicable law.
                 If, after the registration statement becomes effective, the
                 Company advises the holders of registered Registrable
                 Securities that the Company considers it appropriate for the
                 registration statement or any prospectus related thereto to be
                 amended, the holders of such Registrable Securities shall
                 immediately suspend any further sales of their registered
                 Registrable Securities until the Company advises them that the
                 registration statement or prospectus has been amended.

         f.      The holder shall furnish in writing to the Company all
                 information as may be reasonably requested by the Company or
                 required under applicable securities law in connection with any
                 registration of Registrable Securities including, but not
                 limited to, the proposed method of sale or other disposition of
                 the registered Registrable Securities and any compensation
                 payable in connection therewith. The holder and the Company
                 shall comply with the provisions of applicable securities law
                 in connection with the registration of Registrable Securities
                 and the disposition thereof.

         g.      In connection with any registration statement in which the
                 holder's Registrable Securities are included, (i) the holder
                 will indemnify the Company, its directors and officers and each
                 person

                                       5.

                 who controls the Company, against any losses, claims, damages,
                 liabilities and expenses resulting from any untrue or alleged
                 untrue statement of material fact contained in the registration
                 statement, prospectus or preliminary prospectus or any
                 amendment thereof or supplement thereto or any omission or
                 alleged omission of a material fact required to be stated
                 therein or necessary to make the statements therein not
                 misleading, but only to the extent that such untrue statement
                 or omission is contained in or should be contained in any
                 information furnished in writing by the holder, and (ii) the
                 Company will indemnify the holder, its directors and officers
                 and each person who controls the holder, against losses, which
                 shall be limited to the actual amount of the loss incurred on
                 the date of the event which invokes the right of
                 indemnification, resulting from any untrue or alleged untrue
                 statement of material fact contained in the registration
                 statement, prospectus or preliminary prospectus or any
                 amendment thereof or supplement thereto or any omission or
                 alleged omission of a material fact required to be stated
                 therein or necessary to make the statements therein not
                 misleading, except insofar as such losses are caused by any
                 untrue statement or omission contained in information furnished
                 in writing to the Company by such holder.

         h.      The Company's obligation to include Registrable Securities in a
                 registration under this Section 7 shall terminate on the
                 earlier of: (i) the close of business on the date six (6) years
                 from the date of original issuance of the Interim Warrant, and
                 (ii) the date on which, in the opinion of legal counsel to the
                 Company, the particular Registrable Securities which the holder
                 may request be included in such registration statement may be
                 transferred or reissued without restriction, in compliance with
                 the provisions of Rule 144(k) under the Act, or any successor
                 provision.

8.       Compliance with Securities Laws and Other Transfer Restrictions.

         a.      The holder of this Interim Warrant, by acceptance hereof,
                 agrees, represents and warrants that this Interim Warrant and
                 the Warrant Shares which may be issued upon exercise hereof are
                 being acquired for investment, that the holder has no present
                 intention to resell or otherwise dispose of all or any part of
                 this Interim Warrant or any Warrant Shares, and that the holder
                 will not offer, sell or otherwise dispose of all or any part of
                 this Interim Warrant or any Warrant Shares except under
                 circumstances which will not result in a violation of the Act
                 or applicable state securities laws. The Company may condition
                 any transfer, sale, pledge, assignment or other disposition on
                 the receipt from the party to whom this Interim Warrant is to
                 be so transferred or to whom Warrant Shares are to be issued or
                 so transferred, of any representations and agreements requested
                 by the Company in order to permit such issuance or transfer to
                 be made pursuant to exemptions from registration under federal
                 and applicable state securities laws. Upon exercise of this
                 Interim Warrant, the holder hereof shall, if requested by the
                 Company, confirm in writing holder's investment purpose and
                 acceptance of the restrictions on transfer of the Warrant
                 Shares, as well as any representations and agreements requested
                 by the Company in order to permit the issuance of Warrant
                 Shares to be made pursuant to exemptions from registration
                 under federal and applicable state securities laws.

         b.      If the Company conducts an Initial Public Offering of its
                 Common Stock or undertakes to file a registration statement
                 pursuant to Subsection 7(a), the holder of the Interim Warrant
                 or any Warrant Shares shall not, without the prior written
                 consent of the Company and the managing underwriter in such
                 offering: (i) sell, transfer or otherwise dispose of, or agree
                 to sell, transfer or otherwise dispose of the Interim Warrant
                 or any of the Warrant Shares; (ii) sell, transfer or

                                       6.

<PAGE>

                 otherwise dispose of, or agree to sell, transfer or otherwise
                 dispose of the Interim Warrant or any right to purchase any of
                 the Warrant Shares; or (iii) sell or grant, or agree to sell or
                 grant, options, rights or warrants with respect to the Interim
                 Warrant or any of the Warrant Shares. Such restrictions shall
                 be effective for a period of time equal to the period during
                 which the managing underwriter imposes such transfer
                 restrictions on the Company's officers and directors; provided,
                 that in no event shall the restricted period applicable to a
                 holder of this Interim Warrant exceed one hundred eighty (180)
                 days after effectiveness of the Company's registration
                 statement filed under the Act with the Securities and Exchange
                 Commission with respect to such offering.

         c.      In the event the holder of this Interim Warrant desires to
                 transfer this Interim Warrant, the holder shall provide the
                 Company with a Form of Assignment, in the form attached hereto
                 describing the manner of such transfer, and an opinion of
                 counsel (reasonably acceptable to the Company) that the
                 proposed transfer may be effected without registration or
                 qualification under applicable securities laws, whereupon such
                 holder shall be entitled to transfer this Interim Warrant in
                 accordance with the notice delivered by such holder to the
                 Company. If, in the opinion of the counsel referred to in this
                 Section, the proposed transfer or disposition described in the
                 written notice given may not be effected without registration
                 or qualification of this Interim Warrant, the Company shall
                 give written notice thereof to the holder hereof, and such
                 holder will limit its activities in respect to such proposed
                 transfer or disposition as, in the opinion of such counsel, are
                 permitted by law. The Company may place one or more restrictive
                 legends on the Interim Warrant or any certificates representing
                 the Warrant Shares which set forth the restrictions contained
                 herein, and may further place a "stop transfer" restriction in
                 the Company's books and records with respect to the Interim
                 Warrant and any Warrant Shares. The restrictions set forth in
                 this Interim Warrant shall be binding upon any holder, donee,
                 assignee or transferee of the Interim Warrant or the Warrant
                 Shares.

9.       Subdivision of Interim Warrant. At the request of the holder of this
         Interim Warrant in connection with a transfer or exercise of a portion
         of the Interim Warrant, upon surrender of such Interim Warrant for such
         purpose to the Company, the Company will issue and exchange therefor
         warrants of like tenor and date representing in the aggregate the right
         to purchase such number of shares of Common Stock as shall be
         designated by such holder at the time of such surrender; provided,
         however, that the Company's obligations to subdivide securities under
         this Section shall be subject to and conditioned upon the compliance of
         any such subdivision with applicable securities laws.

10.      Loss, Theft, Destruction or Mutilation of Interim Warrant. Upon receipt
         by the Company of evidence reasonably satisfactory to it of the loss,
         theft, destruction or mutilation of this Interim Warrant, and in case
         of loss, theft or destruction, of indemnity or security reasonably
         satisfactory to it, and upon reimbursement to the Company of all
         reasonable expenses incidental thereto, and upon surrender and
         cancellation of this Interim Warrant, if mutilated, the Company will
         make and deliver a new Interim Warrant of like tenor and dates as of
         such cancellation, in lieu of this Interim Warrant.

11.      No Limitation on Corporate Action. No provisions of the Interim Warrant
         and no right or option granted or conferred hereunder shall in any way
         limit, affect, or abridge the exercise by the Company of any of its
         corporate rights or powers to recapitalize, amend its Articles of
         Incorporation, reorganize or merge with or into another corporation, or
         to transfer all or any part of its property or assets, or the exercise
         of any other of its corporate rights and powers.

                                       7.

12.      Miscellaneous. This Interim Warrant shall be governed by the laws of
         the state of Minnesota without reference to such state's choice of laws
         provisions. The headings in this Interim Warrant are for purposes of
         convenience and reference only, and shall not be deemed to constitute a
         part hereof. Neither this Interim Warrant nor any term hereof may be
         changed, waived, discharged or terminated orally but only by an
         instrument in writing signed by the Company and the registered holder
         hereof. All notices and other communications from the Company to the
         holder of this Interim Warrant shall be by certified mail, return
         receipt requested, or by overnight delivery service to the address
         furnished to the Company in writing by the last holder of this Interim
         Warrant who shall have furnished an address to the Company in writing.
