                          COMMON STOCK PURCHASE WARRANT

Warrant No. G-1                                                    Shares: 3,750

         THIS CERTIFIES that, subject to the terms and conditions herein set
forth, David G. Mell, or its registered assigns (the "Holder") is entitled to
purchase from Redline Performance Products, Inc., a Minnesota corporation (the
"Company"), at any time or from time to time prior to the time and date set
forth above, three thousand seven hundred fifty (3,750) fully paid and
non-assessable shares of common stock of the Company (such class of stock being
referred to as the "Common Stock" and such shares of Common Stock which may be
acquired upon exercise of this Warrant being referred to as the "Shares").

         This Warrant is subject to the following terms and conditions:

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

2.       Adjustment of Warrant Price and Number of Shares. The number and kind
         of securities issuable upon the exercise of this Warrant shall be
         subject to adjustment from time to time upon the happening of certain
         events as follows:

         a.       Adjustment for Stock Dividends, Splits and Consolidations. In
                  case the Company shall at any time subdivide the outstanding
                  Common Stock into a greater number of shares or declare a
                  dividend payable in Common Stock, the Warrant Price in effect
                  immediately prior to such subdivision shall be proportionately
                  reduced, and

<PAGE>

                  conversely, in case the outstanding Common Stock shall be
                  combined into a smaller number of shares, the Warrant exercise
                  price in effect immediately prior to such combination shall be
                  proportionately increased.

         b.       Adjustment for Reorganizations or Consolidations. 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 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 Warrant and had received upon
                  exercise of this Warrant the Shares prior to such
                  reorganization, reclassification, consolidation, merger or
                  sale, less the amount of the aggregate Warrant Price.

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

4.       No Stockholder Rights. This Warrant shall not entitle its Holder to any
         of the rights of a stockholder of the Company prior to exercise of this
         Warrant.

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

6.       Exercise of Warrant. This Warrant may be exercised by the registered
         Holder, in whole or in part, by the surrender of this Warrant at the
         principal office of the Company, together with the form of exercise
         hereof duly executed, accompanied by payment in full of the amount of
         the aggregate 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 Warrant shall be issued by the Company
         to the registered Holder for the number of Shares of Common Stock with
         respect to which this Warrant shall not have been exercised. Upon each
         exercise of this Warrant the Holder shall exercise this Warrant and
         purchase the lesser of 500 Shares and the balance of Shares available
         for issuance under the Warrant. A 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 Warrant, written notice of exercise, and
         payment for the number of Shares being acquired

                                       2.
<PAGE>

         upon exercise of this Warrant. The person entitled to receive the
         Shares issuable upon such exercise shall be treated for all purposes as
         the Holder of such Shares of record as of the close of business on such
         date. As promptly as practicable on or after such date, the Company
         shall issue and deliver to the person or persons entitled to receive
         the same a certificate or certificates for the number of full Shares of
         Common Stock issuable upon such exercise, together with cash in lieu of
         any fraction of a Share, as provided above.

7.       Compliance with Securities Laws and Other Transfer Restrictions. The
         Holder of this Warrant, by acceptance hereof, agrees, represents and
         warrants that this Warrant and the 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 Warrant or any Shares, and that the Holder will not offer, sell
         or otherwise dispose of all or any part of this Warrant or any Shares
         except under circumstances which will not result in a violation of the
         Securities Act of 1933, as amended (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 Warrant is to be so transferred or to whom Shares are to be issued
         or so transferred, on 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 Warrant, the Holder hereof
         shall, if requested by the Company, confirm in writing its investment
         purpose and acceptance of the restrictions on transfer of the Shares.

8.       Restriction on Transfer After a Public Offering. The Holder understands
         that the Company at a future date may file a registration or offering
         statement (the "Registration Statement") with the Securities and
         Exchange Commission to facilitate a public offering of its securities.
         The Holder 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 undersigned will not, without the prior
         written consent of the Company and such underwriter, during the "Lockup
         Period" as defined herein: (a) sell, transfer or otherwise dispose of,
         or agree to sell, transfer or otherwise dispose of any of the Shares
         beneficially owned by the undersigned during the Lockup Period; (b)
         sell, transfer or otherwise dispose of, or agree to sell, transfer or
         otherwise dispose of any options, rights or warrants to purchase any
         Shares beneficially owned by the undersigned during the Lockup Period;
         or (c) sell or grant, or agree to sell or grant, options, rights or
         warrants with respect to any of the Shares. 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.

9.       Stop Transfer Order and Restrictive Legend. The Holder agrees that the
         Company may place a stop transfer order with its registrar and transfer
         agent (if any) covering all Shares. The Holder agrees that the Company
         may place one or more restrictive legends on any certificates
         evidencing the Shares containing substantially the following language:

                                       3.
<PAGE>
                  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, or
                  transferred in the absence of either an effective registration
                  under the Securities Act of 1933, as amended, and under the
                  applicable state securities laws, or an opinion of counsel for
                  the Company that such transaction is exempt from registration
                  under 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.

10.      Subdivision of Warrant. At the request of the Holder of this Warrant in
         connection with a transfer or exercise of a portion of the Warrant,
         upon surrender of such Warrant for such purpose to the Company, the
         Company at its expense (except for any transfer tax payable) will issue
         and exchange therefor warrants of like tenor and date representing in
         the aggregate the right to purchase such number of Shares of such
         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 Paragraph shall be subject to and
         conditioned upon the compliance of any such subdivision with applicable
         state securities laws and with the Act.

11.      Postponement of Exercise. Notwithstanding anything herein to the
         contrary, the Company shall have the right to delay any exercise for a
         period of up to one hundred eighty (180) days for the purpose of: (a)
         ensuring the availability of an exemption under applicable securities
         laws for the issuance of the Shares to the Holder in light of the
         transactions by the Company in its securities; and/or (b) facilitating
         a distribution of the Company's securities. In either case, if the
         Company elects to delay any such exercise, the Company shall inform the
         Holder, in writing, of such delay and the terms of such delay. Any such
         delay shall not lead to any change in the Warrant Price or the terms of
         the Warrant and shall not extend the term of any Warrant unless such
         delay would extend past the expiration date of such Warrant. In such
         case, the expiration date shall be extended to thirty (30) days after
         the end of such delay.

12.      Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the
         Company of evidence reasonably satisfactory to it of the loss, theft,
         destruction or mutilation of this 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
         Warrant, if mutilated, the Company will make and deliver a new Warrant
         of like tenor and dates as of such cancellation, in lieu of this
         Warrant.

13.      No Limitation on Corporate Action. No provisions of the 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.

                                       4.

14.      Miscellaneous. This Warrant shall be governed by the laws of the State
         of Minnesota without reference to such state's conflict of laws
         provisions. The headings in this Warrant are for purposes of
         convenience and reference only, and shall not be deemed to constitute a

                                  EXERCISE FORM

                       REDLINE PERFORMANCE PRODUCTS, INC.

          (To be executed only upon exercise or conversion of Warrant)

         The undersigned registered owner of this Warrant (the "Investor")
irrevocably exercises or converts this Warrant for and purchases
_____________________________ of the number of Shares of Common Stock (the
"Shares") of __________________ purchasable with this Warrant, and herewith
makes payment therefore (if an exercise), all at the price and on the terms and
conditions specified in this Warrant.

As a condition to the exercise of this Warrant, the Investor represents and
warrants to Company as follows:

15. Investment Intent.

a. Investor has been advised that (i) the sale of the Shares to Investor has not
been registered under the Securities Act of 1933 (the "Act") on the grounds,
among others, that it will be exempt from registration under Section 4(2) of the
Act as a transaction not involving a public offering; (ii) reliance upon such
exemption or exemptions is predicated in part on Investor's representation that
Investor is acquiring such Shares for investment for Investor's own account with
no present intention of dividing Investor's participation with others or
reselling or otherwise distributing the same, and the Investor alone shall have
the full legal and equitable right, title and interest in the Shares; and (iii)
Investor's representations, including the foregoing, are essential to the
reliance of the Company upon exemptions from registration or qualification of
this transaction or the Shares under applicable state securities laws.

b. Investor understands that the effect and intent of Investor's representations
in subparagraph (a) above to be that Investor does not presently contemplate the
disposal of all or any part of the Shares, and that at such time as Investor
determines to dispose of all or any part of the Shares, Investor understands
that Investor must first notify the Company, and that the Company may require an
opinion of its attorney, of Investor's attorney, or both, that such disposition
will not negate Investor's intent as expressed herein, and that, in view of the
exemption claimed, such disposition will be permissible.

c. Investor understands that the subsequent transfer of the Shares will be
restricted, and that the effect of the restrictions on the transfer of the
Shares include the facts, among others, that (i) Investor will not have
liquidity with respect to the Shares for an indefinite period of time, and (ii)
Investor will be unable to sell, encumber or otherwise transfer the Shares
unless there is an effective registration statement covering such disposition
under the Act, and effective registrations and qualifications under applicable
state law, or exemptions from such registrations or qualifications under the Act
and state law are applicable.

d. Investor recognizes that an investment in the Shares involves a high degree
of risk and that the purchase of the Shares is a long-term investment. Investor
has a financial net worth or anticipated income such that a sale of such Shares
need not be made in the foreseeable future to

                                       2.
<PAGE>

satisfy any financial obligation of which Investor is or contemplates Investor
will become subject.

e. Investor understands that exemptions from the registration and qualification
requirements, as referred to in subparagraph (c) above, may not be available to
Investor, and the Company will have no obligation to assist Investor in
registering or qualifying a disposition of the Shares or in obtaining or
establishing an exemption from such registration or qualification requirements.

f. Investor understands that any certificate representing the Shares will bear
legends stating in effect that the issuance or sale of the Shares has not been
registered under the Act or any applicable state securities laws and the
Investor may not sell the Shares or other securities within 180 days of an
initial public offering by the Company, and such legends may refer to the
restrictions on transfers and sales contained in this Agreement. In addition,
any certificates representing the Shares issued to an Investor who is a resident
of a particular state may bear a legend containing language required by the laws
of such State. Investor further understands that a stop-transfer restriction may
be placed in the books and records of the Company with respect to the Shares.

g. Investor's purchase of the Shares is not the result of any general
solicitation or general advertising, including, but not limited to: (i) any
advertisement, article, notice or other communication published in any
newspaper, magazine or similar media or broadcast over television or radio; and
(ii) any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising.

16. State of Residence. Investor represents and warrants to the Company that
Investor is a bona fide resident of, and is domiciled in, the State of
_____________________.

17. Accredited Investor Status.

a. Investor understands that Investor is an "accredited investor" only if:

                  (1)      Investor's individual income from all sources for
                           each of the two most recent calendar years was in
                           excess of $200,000 and Investor reasonably expects
                           Investor's individual income from all sources
                           anticipated for the current calendar year to be in
                           excess of $200,000; or

                  (2)      Investor's joint income with Investor's spouse from
                           all sources for each of the two most recent calendar
                           years was in excess of $300,000 and Investor
                           reasonably expects Investor's joint income with
                           Investor's spouse from all sources anticipated for
                           the current calendar year to be in excess of
                           $300,000; or

                  (3)      Investor's individual net worth, or Investor's joint
                           net worth with Investor's spouse, at fair market
                           value (including home, furnishings and personal
                           automobiles) is greater than $1,000,000; or

                  (4)      Investor otherwise meets the definition of an
                           "accredited investor."

                                       3.
<PAGE>

b. Based on the foregoing information, Investor represents and warrants to the
Company that Investor:

                  (1)      IS an accredited investor (check here):           [ ]

                  (2)      IS NOT an accredited investor (check here):       [ ]

18. Knowledge and Experience. Investor represents and warrants to the Company as
follows:

a. Investor (i) believes Investor has such knowledge and experience in financial
and business matters that Investor is capable of evaluating the merits and risks
of the prospective investment in the Shares or (ii) if Investor does not so
believe, or if Investor has been instructed by the Company to designate a
purchaser representative to supplement Investor's knowledge and experience for

representative, together with the undersigned, have such knowledge and
experience in financial and business matters that they are capable of evaluating
the merits and risks of the prospective investment in the Shares.

b. In addition to designating a purchaser representative to the extent required
by the Company, if any, Investor has obtained, to the extent Investor deems
necessary, personal and professional advice with respect to the risks inherent
in the investment in the Shares in light of Investor's financial condition and
investment needs.

access to full and complete information regarding the Company and has utilized

either attended or been given reasonable opportunity to attend a meeting with
representatives of the Company for the purpose of asking questions of, and
receiving answers from, such representatives concerning the Company and the
Shares and to obtain any additional information, to the extent reasonably
available.

                       REDLINE PERFORMANCE PRODUCTS, INC.

                          COMMON STOCK PURCHASE WARRANT

Warrant No. G-9                                                    Shares: 2,917

         THIS CERTIFIES that, subject to the terms and conditions herein set
forth, David G. Mell, or its registered assigns (the "Holder") is entitled to
purchase from Redline Performance Products, Inc., a Minnesota corporation (the
"Company"), at any time or from time to time prior to the time and date set
forth above, two thousand nine hundred seventeen (2,917) fully paid and
non-assessable shares of common stock of the Company (such class of stock being
referred to as the "Common Stock" and such shares of Common Stock which may be
acquired upon exercise of this Warrant being referred to as the "Shares").

         This Warrant is subject to the following terms and conditions:

1.       Purchase Price. Subject to adjustment as hereinafter provided, the
         purchase price of one Share shall be Three and 75/100 Dollars ($3.75).
         The purchase price of one Share is referred to herein as the "Warrant
         Price."

2.       Adjustment of Warrant Price and Number of Shares. The number and kind
         of securities issuable upon the exercise of this Warrant shall be
         subject to adjustment from time to time upon the happening of certain
         events as follows:

         a.       Adjustment for Stock Dividends, Splits and Consolidations. In
                  case the Company shall at any time subdivide the outstanding
                  Common Stock into a greater number of shares or declare a
                  dividend payable in Common Stock, the Warrant Price in effect
                  immediately prior to such subdivision shall be proportionately
                  reduced, and conversely, in case the outstanding Common Stock
                  shall be combined into a

<PAGE>

                  smaller number of shares, the Warrant exercise price in effect
                  immediately prior to such combination shall be proportionately
                  increased.

         b.       Adjustment for Reorganizations or Consolidations. 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 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 Warrant and had received upon
                  exercise of this Warrant the Shares prior to such
                  reorganization, reclassification, consolidation, merger or
                  sale, less the amount of the aggregate Warrant Price.

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

4.       No Stockholder Rights. This Warrant shall not entitle its Holder to any
         of the rights of a stockholder of the Company prior to exercise of this
         Warrant.

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

6.       Exercise of Warrant. This Warrant may be exercised by the registered
         Holder, in whole or in part, by the surrender of this Warrant at the
         principal office of the Company, together with the form of exercise
         hereof duly executed, accompanied by payment in full of the amount of
         the aggregate 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 Warrant shall be issued by the Company
         to the registered Holder for the number of Shares of Common Stock with
         respect to which this Warrant shall not have been exercised. Upon each
         exercise of this Warrant the Holder shall exercise this Warrant and
         purchase the lesser of 500 Shares and the balance of Shares available
         for issuance under the Warrant. A 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 Warrant, written notice of exercise, and
         payment for the number of Shares being acquired upon exercise of this
         Warrant. The person entitled to receive the Shares issuable upon

                                       2.
<PAGE>

         such exercise shall be treated for all purposes as the Holder of such
         Shares of record as of the close of business on such date. As promptly
         as practicable on or after such date, the Company shall issue and
         deliver to the person or persons entitled to receive the same a
         certificate or certificates for the number of full Shares of Common
         Stock issuable upon such exercise, together with cash in lieu of any
         fraction of a Share, as provided above.

7.       Compliance with Securities Laws and Other Transfer Restrictions. The
         Holder of this Warrant, by acceptance hereof, agrees, represents and
         warrants that this Warrant and the 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 Warrant or any Shares, and that the Holder will not offer, sell
         or otherwise dispose of all or any part of this Warrant or any Shares
         except under circumstances which will not result in a violation of the
         Securities Act of 1933, as amended (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 Warrant is to be so transferred or to whom Shares are to be issued
         or so transferred, on 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 Warrant, the Holder hereof
         shall, if requested by the Company, confirm in writing its investment
         purpose and acceptance of the restrictions on transfer of the Shares.

8.       Restriction on Transfer After a Public Offering. The Holder understands
         that the Company at a future date may file a registration or offering
         statement (the "Registration Statement") with the Securities and
         Exchange Commission to facilitate a public offering of its securities.
         The Holder 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 undersigned will not, without the prior
         written consent of the Company and such underwriter, during the "Lockup
         Period" as defined herein: (a) sell, transfer or otherwise dispose of,
         or agree to sell, transfer or otherwise dispose of any of the Shares
         beneficially owned by the undersigned during the Lockup Period; (b)
         sell, transfer or otherwise dispose of, or agree to sell, transfer or
         otherwise dispose of any options, rights or warrants to purchase any
         Shares beneficially owned by the undersigned during the Lockup Period;
         or (c) sell or grant, or agree to sell or grant, options, rights or
         warrants with respect to any of the Shares. 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.

9.       Stop Transfer Order and Restrictive Legend. The Holder agrees that the
         Company may place a stop transfer order with its registrar and transfer
         agent (if any) covering all Shares. The Holder agrees that the Company
         may place one or more restrictive legends on any certificates
         evidencing the Shares containing substantially the following language:

                                       3.
<PAGE>
                  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, or
                  transferred in the absence of either an effective registration
                  under the Securities Act of 1933, as amended, and under the
                  applicable state securities laws, or an opinion of counsel for
                  the Company that such transaction is exempt from registration
                  under 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.

10.      Subdivision of Warrant. At the request of the Holder of this Warrant in
         connection with a transfer or exercise of a portion of the Warrant,
         upon surrender of such Warrant for such purpose to the Company, the
         Company at its expense (except for any transfer tax payable) will issue
         and exchange therefor warrants of like tenor and date representing in
         the aggregate the right to purchase such number of Shares of such
         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 Paragraph shall be subject to and
         conditioned upon the compliance of any such subdivision with applicable
         state securities laws and with the Act.

11.      Postponement of Exercise. Notwithstanding anything herein to the
         contrary, the Company shall have the right to delay any exercise for a
         period of up to one hundred eighty (180) days for the purpose of: (a)
         ensuring the availability of an exemption under applicable securities
         laws for the issuance of the Shares to the Holder in light of the
         transactions by the Company in its securities; and/or (b) facilitating
         a distribution of the Company's securities. In either case, if the
         Company elects to delay any such exercise, the Company shall inform the
         Holder, in writing, of such delay and the terms of such delay. Any such
         delay shall not lead to any change in the Warrant Price or the terms of
         the Warrant and shall not extend the term of any Warrant unless such
         delay would extend past the expiration date of such Warrant. In such
         case, the expiration date shall be extended to thirty (30) days after
         the end of such delay.

12.      Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the
         Company of evidence reasonably satisfactory to it of the loss, theft,
         destruction or mutilation of this 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
         Warrant, if mutilated, the Company will make and deliver a new Warrant
         of like tenor and dates as of such cancellation, in lieu of this
         Warrant.

13.      No Limitation on Corporate Action. No provisions of the 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.

                                       4.

14.      Miscellaneous. This Warrant shall be governed by the laws of the State
         of Minnesota without reference to such state's conflict of laws
         provisions. The headings in this Warrant are for purposes of
         convenience and reference only, and shall not be deemed to constitute a

                                  EXERCISE FORM

                       REDLINE PERFORMANCE PRODUCTS, INC.

          (To be executed only upon exercise or conversion of Warrant)

         The undersigned registered owner of this Warrant (the "Investor")
irrevocably exercises or converts this Warrant for and purchases
_____________________________ of the number of Shares of Common Stock (the
"Shares") of __________________ purchasable with this Warrant, and herewith
makes payment therefore (if an exercise), all at the price and on the terms and
conditions specified in this Warrant.

As a condition to the exercise of this Warrant, the Investor represents and
warrants to Company as follows:

1. Investment Intent.

a. Investor has been advised that (i) the sale of the Shares to Investor has not
been registered under the Securities Act of 1933 (the "Act") on the grounds,
among others, that it will be exempt from registration under Section 4(2) of the
Act as a transaction not involving a public offering; (ii) reliance upon such
exemption or exemptions is predicated in part on Investor's representation that
Investor is acquiring such Shares for investment for Investor's own account with
no present intention of dividing Investor's participation with others or
reselling or otherwise distributing the same, and the Investor alone shall have
the full legal and equitable right, title and interest in the Shares; and (iii)
Investor's representations, including the foregoing, are essential to the
reliance of the Company upon exemptions from registration or qualification of
this transaction or the Shares under applicable state securities laws.

b. Investor understands that the effect and intent of Investor's representations
in subparagraph (a) above to be that Investor does not presently contemplate the
disposal of all or any part of the Shares, and that at such time as Investor
determines to dispose of all or any part of the Shares, Investor understands
that Investor must first notify the Company, and that the Company may require an
opinion of its attorney, of Investor's attorney, or both, that such disposition
will not negate Investor's intent as expressed herein, and that, in view of the
exemption claimed, such disposition will be permissible.

c. Investor understands that the subsequent transfer of the Shares will be
restricted, and that the effect of the restrictions on the transfer of the
Shares include the facts, among others, that (i) Investor will not have
liquidity with respect to the Shares for an indefinite period of time, and (ii)
Investor will be unable to sell, encumber or otherwise transfer the Shares
unless there is an effective registration statement covering such disposition
under the Act, and effective registrations and qualifications under applicable
state law, or exemptions from such registrations or qualifications under the Act
and state law are applicable.

d. Investor recognizes that an investment in the Shares involves a high degree
of risk and that the purchase of the Shares is a long-term investment. Investor
has a financial net worth or

<PAGE>

anticipated income such that a sale of such Shares need not be made in the
foreseeable future to satisfy any financial obligation of which Investor is or
contemplates Investor will become subject.

e. Investor understands that exemptions from the registration and qualification
requirements, as referred to in subparagraph (c) above, may not be available to
Investor, and the Company will have no obligation to assist Investor in
registering or qualifying a disposition of the Shares or in obtaining or
establishing an exemption from such registration or qualification requirements.

f. Investor understands that any certificate representing the Shares will bear
legends stating in effect that the issuance or sale of the Shares has not been
registered under the Act or any applicable state securities laws and the
Investor may not sell the Shares or other securities within 180 days of an
initial public offering by the Company, and such legends may refer to the
restrictions on transfers and sales contained in this Agreement. In addition,
any certificates representing the Shares issued to an Investor who is a resident
of a particular state may bear a legend containing language required by the laws
of such State. Investor further understands that a stop-transfer restriction may
be placed in the books and records of the Company with respect to the Shares.

g. Investor's purchase of the Shares is not the result of any general
solicitation or general advertising, including, but not limited to: (i) any
advertisement, article, notice or other communication published in any
newspaper, magazine or similar media or broadcast over television or radio; and
(ii) any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising.

2. State of Residence. Investor represents and warrants to the Company that
Investor is a bona fide resident of, and is domiciled in, the State of
_____________________.

3. Accredited Investor Status.

a. Investor understands that Investor is an "accredited investor" only if:

                  (1)      Investor's individual income from all sources for
                           each of the two most recent calendar years was in
                           excess of $200,000 and Investor reasonably expects
                           Investor's individual income from all sources
                           anticipated for the current calendar year to be in
                           excess of $200,000; or

                  (2)      Investor's joint income with Investor's spouse from
                           all sources for each of the two most recent calendar
                           years was in excess of $300,000 and Investor
                           reasonably expects Investor's joint income with
                           Investor's spouse from all sources anticipated for
                           the current calendar year to be in excess of
                           $300,000; or

<PAGE>

                  (4)      Investor otherwise meets the definition of an
                           "accredited investor."

                       REDLINE PERFORMANCE PRODUCTS, INC.

                          COMMON STOCK PURCHASE WARRANT

Warrant No. G-13                                                   Shares: 2,084

         THIS CERTIFIES that, subject to the terms and conditions herein set
forth, David G. Mell, or its registered assigns (the "Holder") is entitled to
purchase from Redline Performance Products, Inc., a Minnesota corporation (the
"Company"), at any time or from time to time prior to the time and date set
forth above, two thousand eighty-four (2,084) fully paid and non-assessable
shares of common stock of the Company (such class of stock being referred to as
the "Common Stock" and such shares of Common Stock which may be acquired upon
exercise of this Warrant being referred to as the "Shares").

         This Warrant is subject to the following terms and conditions:

1.       Purchase Price. Subject to adjustment as hereinafter provided, the
         purchase price of one Share shall be Three and 75/100 Dollars ($3.75).
         The purchase price of one Share is referred to herein as the "Warrant
         Price."

2.       Adjustment of Warrant Price and Number of Shares. The number and kind
         of securities issuable upon the exercise of this Warrant shall be
         subject to adjustment from time to time upon the happening of certain
         events as follows:

         a.       Adjustment for Stock Dividends, Splits and Consolidations. In
                  case the Company shall at any time subdivide the outstanding
                  Common Stock into a greater number of shares or declare a
                  dividend payable in Common Stock, the Warrant Price in effect
                  immediately prior to such subdivision shall be proportionately
                  reduced, and conversely, in case the outstanding Common Stock
                  shall be combined into a

<PAGE>

                  smaller number of shares, the Warrant exercise price in effect
                  immediately prior to such combination shall be proportionately
                  increased.

         b.       Adjustment for Reorganizations or Consolidations. 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 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 Warrant and had received upon
                  exercise of this Warrant the Shares prior to such
                  reorganization, reclassification, consolidation, merger or
                  sale, less the amount of the aggregate Warrant Price.

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

4.       No Stockholder Rights. This Warrant shall not entitle its Holder to any
         of the rights of a stockholder of the Company prior to exercise of this
         Warrant.

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

6.       Exercise of Warrant. This Warrant may be exercised by the registered
         Holder, in whole or in part, by the surrender of this Warrant at the
         principal office of the Company, together with the form of exercise
         hereof duly executed, accompanied by payment in full of the amount of
         the aggregate 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 Warrant shall be issued by the Company
         to the registered Holder for the number of Shares of Common Stock with
         respect to which this Warrant shall not have been exercised. Upon each
         exercise of this Warrant the Holder shall exercise this Warrant and
         purchase the lesser of 500 Shares and the balance of Shares available
         for issuance under the Warrant. A 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

                                       2.
<PAGE>

         Warrant, written notice of exercise, and payment for the number of
         Shares being acquired upon exercise of this Warrant. The person
         entitled to receive the Shares issuable upon such exercise shall be
         treated for all purposes as the Holder of such Shares of record as of
         the close of business on such date. As promptly as practicable on or
         after such date, the Company shall issue and deliver to the person or
         persons entitled to receive the same a certificate or certificates for
         the number of full Shares of Common Stock issuable upon such exercise,
         together with cash in lieu of any fraction of a Share, as provided
         above.

7.       Compliance with Securities Laws and Other Transfer Restrictions. The
         Holder of this Warrant, by acceptance hereof, agrees, represents and
         warrants that this Warrant and the 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 Warrant or any Shares, and that the Holder will not offer, sell
         or otherwise dispose of all or any part of this Warrant or any Shares
         except under circumstances which will not result in a violation of the
         Securities Act of 1933, as amended (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 Warrant is to be so transferred or to whom Shares are to be issued
         or so transferred, on 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 Warrant, the Holder hereof
         shall, if requested by the Company, confirm in writing its investment
         purpose and acceptance of the restrictions on transfer of the Shares.

8.       Restriction on Transfer After a Public Offering. The Holder understands
         that the Company at a future date may file a registration or offering
         statement (the "Registration Statement") with the Securities and
         Exchange Commission to facilitate a public offering of its securities.
         The Holder 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 undersigned will not, without the prior
         written consent of the Company and such underwriter, during the "Lockup
         Period" as defined herein: (a) sell, transfer or otherwise dispose of,
         or agree to sell, transfer or otherwise dispose of any of the Shares
         beneficially owned by the undersigned during the Lockup Period; (b)
         sell, transfer or otherwise dispose of, or agree to sell, transfer or
         otherwise dispose of any options, rights or warrants to purchase any
         Shares beneficially owned by the undersigned during the Lockup Period;
         or (c) sell or grant, or agree to sell or grant, options, rights or
         warrants with respect to any of the Shares. 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.

                                       3.
<PAGE>
9.       Stop Transfer Order and Restrictive Legend. The Holder agrees that the
         Company may place a stop transfer order with its registrar and transfer
         agent (if any) covering all Shares. The Holder agrees that the Company
         may place one or more restrictive legends on any certificates
         evidencing the 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, or
                  transferred in the absence of either an effective registration
                  under the Securities Act of 1933, as amended, and under the
                  applicable state securities laws, or an opinion of counsel for
                  the Company that such transaction is exempt from registration
                  under 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.

10.      Subdivision of Warrant. At the request of the Holder of this Warrant in
         connection with a transfer or exercise of a portion of the Warrant,
         upon surrender of such Warrant for such purpose to the Company, the
         Company at its expense (except for any transfer tax payable) will issue
         and exchange therefor warrants of like tenor and date representing in
         the aggregate the right to purchase such number of Shares of such
         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 Paragraph shall be subject to and
         conditioned upon the compliance of any such subdivision with applicable
         state securities laws and with the Act.

11.      Postponement of Exercise. Notwithstanding anything herein to the
         contrary, the Company shall have the right to delay any exercise for a
         period of up to one hundred eighty (180) days for the purpose of: (a)
         ensuring the availability of an exemption under applicable securities
         laws for the issuance of the Shares to the Holder in light of the
         transactions by the Company in its securities; and/or (b) facilitating
         a distribution of the Company's securities. In either case, if the
         Company elects to delay any such exercise, the Company shall inform the
         Holder, in writing, of such delay and the terms of such delay. Any such
         delay shall not lead to any change in the Warrant Price or the terms of
         the Warrant and shall not extend the term of any Warrant unless such
         delay would extend past the expiration date of such Warrant. In such
         case, the expiration date shall be extended to thirty (30) days after
         the end of such delay.

12.      Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the
         Company of evidence reasonably satisfactory to it of the loss, theft,
         destruction or mutilation of this 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
         Warrant, if mutilated, the Company will make and deliver a new Warrant
         of like tenor and dates as of such cancellation, in lieu of this
         Warrant.

                                       4.
<PAGE>

13.      No Limitation on Corporate Action. No provisions of the 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.

14.      Miscellaneous. This Warrant shall be governed by the laws of the State
         of Minnesota without reference to such state's conflict of laws
         provisions. The headings in this Warrant are for purposes of
         convenience and reference only, and shall not be deemed to constitute a
         part hereof. Neither this 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
         Warrant shall be by certified mail, return receipt requested, or by

                                  EXERCISE FORM

                       REDLINE PERFORMANCE PRODUCTS, INC.

          (To be executed only upon exercise or conversion of Warrant)

         The undersigned registered owner of this Warrant (the "Investor")
irrevocably exercises or converts this Warrant for and purchases
_____________________________ of the number of Shares of Common Stock (the
"Shares") of __________________ purchasable with this Warrant, and herewith
makes payment therefore (if an exercise), all at the price and on the terms and
conditions specified in this Warrant.

As a condition to the exercise of this Warrant, the Investor represents and
warrants to Company as follows:

1. Investment Intent.

a. Investor has been advised that (i) the sale of the Shares to Investor has not
been registered under the Securities Act of 1933 (the "Act") on the grounds,
among others, that it will be exempt from registration under Section 4(2) of the
Act as a transaction not involving a public offering; (ii) reliance upon such
exemption or exemptions is predicated in part on Investor's representation that
Investor is acquiring such Shares for investment for Investor's own account with
no present intention of dividing Investor's participation with others or
reselling or otherwise distributing the same, and the Investor alone shall have
the full legal and equitable right, title and interest in the Shares; and (iii)
Investor's representations, including the foregoing, are essential to the
reliance of the Company upon exemptions from registration or qualification of
this transaction or the Shares under applicable state securities laws.

b. Investor understands that the effect and intent of Investor's representations
in subparagraph (a) above to be that Investor does not presently contemplate the
disposal of all or any part of the Shares, and that at such time as Investor
determines to dispose of all or any part of the Shares, Investor understands
that Investor must first notify the Company, and that the Company may require an
opinion of its attorney, of Investor's attorney, or both, that such disposition
will not negate Investor's intent as expressed herein, and that, in view of the
exemption claimed, such disposition will be permissible.

c. Investor understands that the subsequent transfer of the Shares will be
restricted, and that the effect of the restrictions on the transfer of the
Shares include the facts, among others, that (i) Investor will not have
liquidity with respect to the Shares for an indefinite period of time, and (ii)
Investor will be unable to sell, encumber or otherwise transfer the Shares
unless there is an effective registration statement covering such disposition
under the Act, and effective registrations and qualifications under applicable
state law, or exemptions from such registrations or qualifications under the Act
and state law are applicable.

d. Investor recognizes that an investment in the Shares involves a high degree
of risk and that the purchase of the Shares is a long-term investment. Investor
has a financial net worth or

                                       7.
<PAGE>

anticipated income such that a sale of such Shares need not be made in the
foreseeable future to satisfy any financial obligation of which Investor is or
contemplates Investor will become subject.

e. Investor understands that exemptions from the registration and qualification
requirements, as referred to in subparagraph (c) above, may not be available to
Investor, and the Company will have no obligation to assist Investor in
registering or qualifying a disposition of the Shares or in obtaining or
establishing an exemption from such registration or qualification requirements.

f. Investor understands that any certificate representing the Shares will bear
legends stating in effect that the issuance or sale of the Shares has not been
registered under the Act or any applicable state securities laws and the
Investor may not sell the Shares or other securities within 180 days of an
initial public offering by the Company, and such legends may refer to the
restrictions on transfers and sales contained in this Agreement. In addition,
any certificates representing the Shares issued to an Investor who is a resident
of a particular state may bear a legend containing language required by the laws
of such State. Investor further understands that a stop-transfer restriction may
be placed in the books and records of the Company with respect to the Shares.

g. Investor's purchase of the Shares is not the result of any general
solicitation or general advertising, including, but not limited to: (i) any
advertisement, article, notice or other communication published in any
newspaper, magazine or similar media or broadcast over television or radio; and
(ii) any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising.

2. State of Residence. Investor represents and warrants to the Company that
Investor is a bona fide resident of, and is domiciled in, the State of
_____________________.

3. Accredited Investor Status.

a. Investor understands that Investor is an "accredited investor" only if:

                  (1)      Investor's individual income from all sources for
                           each of the two most recent calendar years was in

                       REDLINE PERFORMANCE PRODUCTS, INC.

                          COMMON STOCK PURCHASE WARRANT

Warrant No. G-13                                                   Shares: 2,084

         THIS CERTIFIES that, subject to the terms and conditions herein set
forth, David G. Mell, or its registered assigns (the "Holder") is entitled to
purchase from Redline Performance Products, Inc., a Minnesota corporation (the
"Company"), at any time or from time to time prior to the time and date set
forth above, two thousand eighty-four (2,084) fully paid and non-assessable
shares of common stock of the Company (such class of stock being referred to as
the "Common Stock" and such shares of Common Stock which may be acquired upon
exercise of this Warrant being referred to as the "Shares").

         This Warrant is subject to the following terms and conditions:

1.       Purchase Price. Subject to adjustment as hereinafter provided, the
         purchase price of one Share shall be Three and 75/100 Dollars ($3.75).
         The purchase price of one Share is referred to herein as the "Warrant
         Price."

2.       Adjustment of Warrant Price and Number of Shares. The number and kind
         of securities issuable upon the exercise of this Warrant shall be
         subject to adjustment from time to time upon the happening of certain
         events as follows:

         a.       Adjustment for Stock Dividends, Splits and Consolidations. In
                  case the Company shall at any time subdivide the outstanding
                  Common Stock into a greater number of shares or declare a
                  dividend payable in Common Stock, the Warrant Price in effect
                  immediately prior to such subdivision shall be proportionately
                  reduced, and conversely, in case the outstanding Common Stock
                  shall be combined into a

<PAGE>

                  smaller number of shares, the Warrant exercise price in effect
                  immediately prior to such combination shall be proportionately
                  increased.

         b.       Adjustment for Reorganizations or Consolidations. 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 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 Warrant and had received upon
                  exercise of this Warrant the Shares prior to such
                  reorganization, reclassification, consolidation, merger or
                  sale, less the amount of the aggregate Warrant Price.

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

4.       No Stockholder Rights. This Warrant shall not entitle its Holder to any
         of the rights of a stockholder of the Company prior to exercise of this
         Warrant.

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

6.       Exercise of Warrant. This Warrant may be exercised by the registered
         Holder, in whole or in part, by the surrender of this Warrant at the
         principal office of the Company, together with the form of exercise
         hereof duly executed, accompanied by payment in full of the amount of
         the aggregate 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 Warrant shall be issued by the Company
         to the registered Holder for the number of Shares of Common Stock with
         respect to which this Warrant shall not have been exercised. Upon each
         exercise of this Warrant the Holder shall exercise this Warrant and
         purchase the lesser of 500 Shares and the balance of Shares available
         for issuance under the Warrant. A 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

                                       2.
<PAGE>

         Warrant, written notice of exercise, and payment for the number of
         Shares being acquired upon exercise of this Warrant. The person
         entitled to receive the Shares issuable upon such exercise shall be
         treated for all purposes as the Holder of such Shares of record as of
         the close of business on such date. As promptly as practicable on or
         after such date, the Company shall issue and deliver to the person or
         persons entitled to receive the same a certificate or certificates for
         the number of full Shares of Common Stock issuable upon such exercise,
         together with cash in lieu of any fraction of a Share, as provided
         above.

7.       Compliance with Securities Laws and Other Transfer Restrictions. The
         Holder of this Warrant, by acceptance hereof, agrees, represents and
         warrants that this Warrant and the 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 Warrant or any Shares, and that the Holder will not offer, sell
         or otherwise dispose of all or any part of this Warrant or any Shares
         except under circumstances which will not result in a violation of the
         Securities Act of 1933, as amended (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 Warrant is to be so transferred or to whom Shares are to be issued
         or so transferred, on 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 Warrant, the Holder hereof
         shall, if requested by the Company, confirm in writing its investment
         purpose and acceptance of the restrictions on transfer of the Shares.

8.       Restriction on Transfer After a Public Offering. The Holder understands
         that the Company at a future date may file a registration or offering
         statement (the "Registration Statement") with the Securities and
         Exchange Commission to facilitate a public offering of its securities.
         The Holder 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 undersigned will not, without the prior
         written consent of the Company and such underwriter, during the "Lockup
         Period" as defined herein: (a) sell, transfer or otherwise dispose of,
         or agree to sell, transfer or otherwise dispose of any of the Shares
         beneficially owned by the undersigned during the Lockup Period; (b)
         sell, transfer or otherwise dispose of, or agree to sell, transfer or
         otherwise dispose of any options, rights or warrants to purchase any
         Shares beneficially owned by the undersigned during the Lockup Period;
         or (c) sell or grant, or agree to sell or grant, options, rights or
         warrants with respect to any of the Shares. 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.

                                       3.
<PAGE>
9.       Stop Transfer Order and Restrictive Legend. The Holder agrees that the
         Company may place a stop transfer order with its registrar and transfer
         agent (if any) covering all Shares. The Holder agrees that the Company
         may place one or more restrictive legends on any certificates
         evidencing the 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, or
                  transferred in the absence of either an effective registration
                  under the Securities Act of 1933, as amended, and under the
                  applicable state securities laws, or an opinion of counsel for
                  the Company that such transaction is exempt from registration
                  under 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.

10.      Subdivision of Warrant. At the request of the Holder of this Warrant in
         connection with a transfer or exercise of a portion of the Warrant,
         upon surrender of such Warrant for such purpose to the Company, the
         Company at its expense (except for any transfer tax payable) will issue
         and exchange therefor warrants of like tenor and date representing in
         the aggregate the right to purchase such number of Shares of such
         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 Paragraph shall be subject to and
         conditioned upon the compliance of any such subdivision with applicable
         state securities laws and with the Act.

11.      Postponement of Exercise. Notwithstanding anything herein to the
         contrary, the Company shall have the right to delay any exercise for a
         period of up to one hundred eighty (180) days for the purpose of: (a)
         ensuring the availability of an exemption under applicable securities
         laws for the issuance of the Shares to the Holder in light of the
         transactions by the Company in its securities; and/or (b) facilitating
         a distribution of the Company's securities. In either case, if the
         Company elects to delay any such exercise, the Company shall inform the
         Holder, in writing, of such delay and the terms of such delay. Any such
         delay shall not lead to any change in the Warrant Price or the terms of
         the Warrant and shall not extend the term of any Warrant unless such
         delay would extend past the expiration date of such Warrant. In such
         case, the expiration date shall be extended to thirty (30) days after
         the end of such delay.

12.      Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the
         Company of evidence reasonably satisfactory to it of the loss, theft,
         destruction or mutilation of this 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
         Warrant, if mutilated, the Company will make and deliver a new Warrant
         of like tenor and dates as of such cancellation, in lieu of this
         Warrant.

                                       4.
<PAGE>

13.      No Limitation on Corporate Action. No provisions of the 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.

14.      Miscellaneous. This Warrant shall be governed by the laws of the State
         of Minnesota without reference to such state's conflict of laws
         provisions. The headings in this Warrant are for purposes of
         convenience and reference only, and shall not be deemed to constitute a
         part hereof. Neither this 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
         Warrant shall be by certified mail, return receipt requested, or by

                                  EXERCISE FORM

                       REDLINE PERFORMANCE PRODUCTS, INC.

          (To be executed only upon exercise or conversion of Warrant)

         The undersigned registered owner of this Warrant (the "Investor")
irrevocably exercises or converts this Warrant for and purchases
_____________________________ of the number of Shares of Common Stock (the
"Shares") of __________________ purchasable with this Warrant, and herewith
makes payment therefore (if an exercise), all at the price and on the terms and
conditions specified in this Warrant.

As a condition to the exercise of this Warrant, the Investor represents and
warrants to Company as follows:

1. Investment Intent.

a. Investor has been advised that (i) the sale of the Shares to Investor has not
been registered under the Securities Act of 1933 (the "Act") on the grounds,
among others, that it will be exempt from registration under Section 4(2) of the
Act as a transaction not involving a public offering; (ii) reliance upon such
exemption or exemptions is predicated in part on Investor's representation that
Investor is acquiring such Shares for investment for Investor's own account with
no present intention of dividing Investor's participation with others or
reselling or otherwise distributing the same, and the Investor alone shall have
the full legal and equitable right, title and interest in the Shares; and (iii)
Investor's representations, including the foregoing, are essential to the
reliance of the Company upon exemptions from registration or qualification of
this transaction or the Shares under applicable state securities laws.

b. Investor understands that the effect and intent of Investor's representations
in subparagraph (a) above to be that Investor does not presently contemplate the
disposal of all or any part of the Shares, and that at such time as Investor
determines to dispose of all or any part of the Shares, Investor understands
that Investor must first notify the Company, and that the Company may require an
opinion of its attorney, of Investor's attorney, or both, that such disposition
will not negate Investor's intent as expressed herein, and that, in view of the
exemption claimed, such disposition will be permissible.

c. Investor understands that the subsequent transfer of the Shares will be
restricted, and that the effect of the restrictions on the transfer of the
Shares include the facts, among others, that (i) Investor will not have
liquidity with respect to the Shares for an indefinite period of time, and (ii)
Investor will be unable to sell, encumber or otherwise transfer the Shares
unless there is an effective registration statement covering such disposition
under the Act, and effective registrations and qualifications under applicable
state law, or exemptions from such registrations or qualifications under the Act
and state law are applicable.

d. Investor recognizes that an investment in the Shares involves a high degree
of risk and that the purchase of the Shares is a long-term investment. Investor
has a financial net worth or

                                       7.
<PAGE>

anticipated income such that a sale of such Shares need not be made in the
foreseeable future to satisfy any financial obligation of which Investor is or

initial public offering by the Company, and such legends may refer to the
restrictions on transfers and sales contained in this Agreement. In addition,
any certificates representing the Shares issued to an Investor who is a resident
of a particular state may bear a legend containing language required by the laws
of such State. Investor further understands that a stop-transfer restriction may
be placed in the books and records of the Company with respect to the Shares.

g. Investor's purchase of the Shares is not the result of any general
solicitation or general advertising, including, but not limited to: (i) any

                       REDLINE PERFORMANCE PRODUCTS, INC.

                          COMMON STOCK PURCHASE WARRANT

Warrant No. G-17                                                     Shares: 667

         THIS CERTIFIES that, subject to the terms and conditions herein set
forth, David G. Mell, or its registered assigns (the "Holder") is entitled to
purchase from Redline Performance Products, Inc., a Minnesota corporation (the
"Company"), at any time or from time to time prior to the time and date set
forth above, six hundred sixty-seven (667) fully paid and non-assessable shares
of common stock of the Company (such class of stock being referred to as the
"Common Stock" and such shares of Common Stock which may be acquired upon
exercise of this Warrant being referred to as the "Shares").

         This Warrant is subject to the following terms and conditions:

1.       Purchase Price. Subject to adjustment as hereinafter provided, the
         purchase price of one Share shall be Three and 75/100 Dollars ($3.75).
         The purchase price of one Share is referred to herein as the "Warrant
         Price."

2.       Adjustment of Warrant Price and Number of Shares. The number and kind
         of securities issuable upon the exercise of this Warrant shall be
         subject to adjustment from time to time upon the happening of certain
         events as follows:

         a.       Adjustment for Stock Dividends, Splits and Consolidations. In
                  case the Company shall at any time subdivide the outstanding
                  Common Stock into a greater number of shares or declare a
                  dividend payable in Common Stock, the Warrant Price in effect
                  immediately prior to such subdivision shall be proportionately
                  reduced, and conversely, in case the outstanding Common Stock
                  shall be combined into a

<PAGE>

                  smaller number of shares, the Warrant exercise price in effect
                  immediately prior to such combination shall be proportionately
                  increased.

         b.       Adjustment for Reorganizations or Consolidations. 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 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 Warrant and had received upon
                  exercise of this Warrant the Shares prior to such
                  reorganization, reclassification, consolidation, merger or
                  sale, less the amount of the aggregate Warrant Price.

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

4.       No Stockholder Rights. This Warrant shall not entitle its Holder to any
         of the rights of a stockholder of the Company prior to exercise of this
         Warrant.

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

6.       Exercise of Warrant. This Warrant may be exercised by the registered
         Holder, in whole or in part, by the surrender of this Warrant at the
         principal office of the Company, together with the form of exercise
         hereof duly executed, accompanied by payment in full of the amount of
         the aggregate 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 Warrant shall be issued by the Company
         to the registered Holder for the number of Shares of Common Stock with
         respect to which this Warrant shall not have been exercised. Upon each
         exercise of this Warrant the Holder shall exercise this Warrant and
         purchase the lesser of 500 Shares and the balance of Shares available
         for issuance under the Warrant. A 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

                                       2.
<PAGE>

         Warrant, written notice of exercise, and payment for the number of
         Shares being acquired upon exercise of this Warrant. The person
         entitled to receive the Shares issuable upon such exercise shall be
         treated for all purposes as the Holder of such Shares of record as of
         the close of business on such date. As promptly as practicable on or
         after such date, the Company shall issue and deliver to the person or
         persons entitled to receive the same a certificate or certificates for
         the number of full Shares of Common Stock issuable upon such exercise,
         together with cash in lieu of any fraction of a Share, as provided
         above.

7.       Compliance with Securities Laws and Other Transfer Restrictions. The
         Holder of this Warrant, by acceptance hereof, agrees, represents and
         warrants that this Warrant and the 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 Warrant or any Shares, and that the Holder will not offer, sell
         or otherwise dispose of all or any part of this Warrant or any Shares
         except under circumstances which will not result in a violation of the
         Securities Act of 1933, as amended (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 Warrant is to be so transferred or to whom Shares are to be issued
         or so transferred, on 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 Warrant, the Holder hereof
         shall, if requested by the Company, confirm in writing its investment
         purpose and acceptance of the restrictions on transfer of the Shares.

8.       Restriction on Transfer After a Public Offering. The Holder understands
         that the Company at a future date may file a registration or offering
         statement (the "Registration Statement") with the Securities and
         Exchange Commission to facilitate a public offering of its securities.
         The Holder 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 undersigned will not, without the prior
         written consent of the Company and such underwriter, during the "Lockup
         Period" as defined herein: (a) sell, transfer or otherwise dispose of,
         or agree to sell, transfer or otherwise dispose of any of the Shares
         beneficially owned by the undersigned during the Lockup Period; (b)
         sell, transfer or otherwise dispose of, or agree to sell, transfer or
         otherwise dispose of any options, rights or warrants to purchase any
         Shares beneficially owned by the undersigned during the Lockup Period;
         or (c) sell or grant, or agree to sell or grant, options, rights or
         warrants with respect to any of the Shares. 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.

                                       3.
<PAGE>
9.       Stop Transfer Order and Restrictive Legend. The Holder agrees that the
         Company may place a stop transfer order with its registrar and transfer
         agent (if any) covering all Shares. The Holder agrees that the Company
         may place one or more restrictive legends on any certificates
         evidencing the 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, or
                  transferred in the absence of either an effective registration
                  under the Securities Act of 1933, as amended, and under the
                  applicable state securities laws, or an opinion of counsel for
                  the Company that such transaction is exempt from registration
                  under 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.

10.      Subdivision of Warrant. At the request of the Holder of this Warrant in
         connection with a transfer or exercise of a portion of the Warrant,
         upon surrender of such Warrant for such purpose to the Company, the
         Company at its expense (except for any transfer tax payable) will issue
         and exchange therefor warrants of like tenor and date representing in
         the aggregate the right to purchase such number of Shares of such
         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 Paragraph shall be subject to and
         conditioned upon the compliance of any such subdivision with applicable
         state securities laws and with the Act.

11.      Postponement of Exercise. Notwithstanding anything herein to the
         contrary, the Company shall have the right to delay any exercise for a
         period of up to one hundred eighty (180) days for the purpose of: (a)
         ensuring the availability of an exemption under applicable securities
         laws for the issuance of the Shares to the Holder in light of the
         transactions by the Company in its securities; and/or (b) facilitating
         a distribution of the Company's securities. In either case, if the
         Company elects to delay any such exercise, the Company shall inform the
         Holder, in writing, of such delay and the terms of such delay. Any such
         delay shall not lead to any change in the Warrant Price or the terms of
         the Warrant and shall not extend the term of any Warrant unless such
         delay would extend past the expiration date of such Warrant. In such
         case, the expiration date shall be extended to thirty (30) days after
         the end of such delay.

12.      Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the
         Company of evidence reasonably satisfactory to it of the loss, theft,
         destruction or mutilation of this 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
         Warrant, if mutilated, the Company will make and deliver a new Warrant
         of like tenor and dates as of such cancellation, in lieu of this
         Warrant.

                                       4.
<PAGE>

13.      No Limitation on Corporate Action. No provisions of the 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.

14.      Miscellaneous. This Warrant shall be governed by the laws of the State
         of Minnesota without reference to such state's conflict of laws
         provisions. The headings in this Warrant are for purposes of
         convenience and reference only, and shall not be deemed to constitute a
         part hereof. Neither this 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
         Warrant shall be by certified mail, return receipt requested, or by

         writing by the last Holder of this Warrant who shall have furnished an
         address to the Company in writing.

                       REDLINE PERFORMANCE PRODUCTS, INC.

          (To be executed only upon exercise or conversion of Warrant)

         The undersigned registered owner of this Warrant (the "Investor")
irrevocably exercises or converts this Warrant for and purchases
_____________________________ of the number of Shares of Common Stock (the
"Shares") of __________________ purchasable with this Warrant, and herewith
makes payment therefore (if an exercise), all at the price and on the terms and
conditions specified in this Warrant.

As a condition to the exercise of this Warrant, the Investor represents and
warrants to Company as follows:

1. Investment Intent.

a. Investor has been advised that (i) the sale of the Shares to Investor has not
been registered under the Securities Act of 1933 (the "Act") on the grounds,
among others, that it will be exempt from registration under Section 4(2) of the
Act as a transaction not involving a public offering; (ii) reliance upon such
exemption or exemptions is predicated in part on Investor's representation that
Investor is acquiring such Shares for investment for Investor's own account with
no present intention of dividing Investor's participation with others or
reselling or otherwise distributing the same, and the Investor alone shall have
the full legal and equitable right, title and interest in the Shares; and (iii)
Investor's representations, including the foregoing, are essential to the
reliance of the Company upon exemptions from registration or qualification of
this transaction or the Shares under applicable state securities laws.

b. Investor understands that the effect and intent of Investor's representations
in subparagraph (a) above to be that Investor does not presently contemplate the
disposal of all or any part of the Shares, and that at such time as Investor
determines to dispose of all or any part of the Shares, Investor understands
that Investor must first notify the Company, and that the Company may require an
opinion of its attorney, of Investor's attorney, or both, that such disposition
will not negate Investor's intent as expressed herein, and that, in view of the
exemption claimed, such disposition will be permissible.

c. Investor understands that the subsequent transfer of the Shares will be
restricted, and that the effect of the restrictions on the transfer of the
Shares include the facts, among others, that (i) Investor will not have
liquidity with respect to the Shares for an indefinite period of time, and (ii)
Investor will be unable to sell, encumber or otherwise transfer the Shares
unless there is an effective registration statement covering such disposition
under the Act, and effective registrations and qualifications under applicable
state law, or exemptions from such registrations or qualifications under the Act
and state law are applicable.

d. Investor recognizes that an investment in the Shares involves a high degree
of risk and that the purchase of the Shares is a long-term investment. Investor
has a financial net worth or

                                       7.

anticipated income such that a sale of such Shares need not be made in the
foreseeable future to satisfy any financial obligation of which Investor is or
contemplates Investor will become subject.

e. Investor understands that exemptions from the registration and qualification
requirements, as referred to in subparagraph (c) above, may not be available to
Investor, and the Company will have no obligation to assist Investor in
registering or qualifying a disposition of the Shares or in obtaining or
establishing an exemption from such registration or qualification requirements.

f. Investor understands that any certificate representing the Shares will bear
legends stating in effect that the issuance or sale of the Shares has not been
registered under the Act or any applicable state securities laws and the
Investor may not sell the Shares or other securities within 180 days of an
initial public offering by the Company, and such legends may refer to the
restrictions on transfers and sales contained in this Agreement. In addition,
any certificates representing the Shares issued to an Investor who is a resident
of a particular state may bear a legend containing language required by the laws
of such State. Investor further understands that a stop-transfer restriction may
be placed in the books and records of the Company with respect to the Shares.

g. Investor's purchase of the Shares is not the result of any general
solicitation or general advertising, including, but not limited to: (i) any
advertisement, article, notice or other communication published in any
newspaper, magazine or similar media or broadcast over television or radio; and
(ii) any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising.

                           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.

12.      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.

13.      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:
         (a) obtaining a "no action" letter from the Commission and applicable
         state securities commissions; (b) 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 (c) registration.

14.      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: (a) 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; (b) 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 (c) 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) 18 months 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.

15.      Restrictive Legend. The Investor agrees that the Company may place one
         or more restrictive legends on any certificates evidencing the
         Securities, including the Warrant Shares and the Founders' 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,

                                       8
<PAGE>

         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 18 months 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.

16.      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.

17.      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.

18.      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.

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

         written explanation or contact the Company to provide additional
         information before the Investor's subscription can be considered.)

         FOR VALUE RECEIVED, the undersigned, Redline Performance Products,
Inc., organized and existing under the laws of the State of Minnesota, whose
mailing address is 2510 Commerce 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, a corporation of the State of Minnesota,
having a mailing address of Union Bank & Trust, Attn: Trust Department, 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 Fifty Thousand and 00/100 Dollars
($50,000.00), together with accrued interest thereon, at the rate of eight
percent (8%) per annum, compounded monthly, at or before 5:00 p.m. Vista,
California time on the earlier of (i) the date ninety (90) days from the date of
this note (the "INTERIM NOTE") or (ii) the date on which the Borrower closes on
the sale of the minimum number of units ($1,250,000) in the Borrower's bridge
financing being conducted in accordance with the terms of the Confidential
Private Placement Memorandum dated August 1, 2002 (each a "MATURITY DATE"). This
Interim Note and the Lender are entitled to all the benefits provided for in the
Interim Loan and Investment Agreement, pursuant to which this indebtedness was
incurred and is to be repaid. The provisions of the Interim Loan and Investment
Agreement are incorporated herein by reference with the same force and effect as
if fully set forth herein.

                  1. Payment. All outstanding principal and accrued interest on
         this Interim Note shall be due and payable on the Maturity Date. All
         payments under this Section shall be made by check mailed by the
         Borrower to the address of the Lender set forth

<PAGE>

         above. 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. If the Borrower fails to pay all amounts outstanding
         under this Interim Note on the Maturity Date, the rate of interest
         under this Interim Note shall be increased to twelve percent (12%) per
         annum and shall accrue from the Maturity Date of this Interim Note
         until payment in full of all amounts due under this Interim Note.

                  2. Subordination; Security. 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; and (ii) 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) 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 Borrower 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. Borrower's repayment of
         all amounts outstanding under this Interim Note shall be secured as
         provided in that certain Security Agreement by and among Borrower and
         Lender.

                  3. Compliance with Securities Laws and Other Transfer
         Restrictions.

a.       The Lender, by acceptance hereof, agrees, represents and warrants that
         this Interim Note is being acquired for investment, that the Lender has
         no present intention to resell or otherwise dispose of all or any part
         of this Interim Note, and that the Lender 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 Securities
         Act of 1933 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. Upon transfer of this Interim Note, the
         transferee shall, if requested by the Borrower, confirm in writing
         transferee's investment purpose and acceptance of the restrictions on
         transfer of the Interim Note, as well as any representations and
         agreements requested by the Borrower in order to permit the transfer of
         the Interim Note to be made pursuant to exemptions from registration
         under federal and applicable state securities laws.

                                       2
<PAGE>

b.       If the Borrower conducts an initial public offering of its Common
         Stock, the Lender 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 underwriter imposes such
         transfer restrictions on the Borrower's officers and directors;
         provided, that in no event shall the restricted period applicable to a
         Lender exceed eighteen (18) months after effectiveness of the
         Borrower's registration statement filed under the Act with the
         Securities and Exchange Commission with respect to such initial public
         offering.

c.       In the event the Lender desires to transfer this Interim Note, the
         Lender 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 Lender shall be
         entitled to transfer this Interim Note in accordance with the notice
         delivered by the Lender 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 Lender, and the
         Lender 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 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 Lender, donee,
         assignee or transferee of the Interim Note.

                  4. No Rights as Shareholder. No right to vote or receive
         dividends or any other rights as a shareholder of the Borrower shall
         exist based on this Interim Note.

                  5. 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 waives diligence, presentment, demand for payment,
         notice of dishonor, notice of non-payment, protest, notice of protest,
         and any and all other demands

                                       3
<PAGE>

         in connection with the delivery, acceptance, performance, default or
         enforcement of 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.

e.       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.

f.       This Interim Note has been issued pursuant to and is subject to the
         terms and provisions of that certain Interim 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 Loan and
         Investment Agreement are inconsistent, the terms of this Interim Note
         shall control.

g.       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 Lender 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.

                          COMMON STOCK PURCHASE WARRANT

Interim Warrant No. IW-1                                          Shares: 5,000

         THIS CERTIFIES that, subject to the terms and conditions herein set
forth, INDUSTRICORP & CO., INC. FBO TWIN CITIES CARPENTERS PENSION FUND or its
registered assigns (the "HOLDER") is entitled to purchase from REDLINE
PERFORMANCE PRODUCTS, INC., a Minnesota corporation (the "COMPANY"), at any time
or from time to time prior to the time and date set forth above, Five Thousand
(5,000) fully paid and non-assessable shares of common stock of the Company (the
"COMMON STOCK"). Such shares of Common Stock which may be acquired upon exercise
of this Interim Warrant are referred to as the "SHARES").

         This Interim Warrant (the "INTERIM WARRANT") is subject to the
following terms and conditions:

1.       Purchase Price. Subject to adjustment as hereinafter provided, the
         purchase price of one Share shall be Three and 75/100 Dollars ($3.75).
         The purchase price of one Share is referred to herein as the "INTERIM
         WARRANT PRICE."

2.       Adjustment of Interim Warrant Price and Number of Shares. The number
         and kind of securities issuable upon the exercise of this Interim
         Warrant shall be subject to adjustment from time to time upon the
         happening of certain events as follows:

<PAGE>

         a.       Adjustment for Stock Dividends, Splits and Consolidations. In
                  case the Company shall at any time subdivide the 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
                  proportionately reduced, and conversely, in case the
                  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.

         b.       Adjustment for Reorganizations or Consolidations. 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 Shares
                  prior to such reorganization, reclassification, consolidation,
                  merger or sale, less the amount of the Interim Warrant Price.

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

4.       No Stockholder Rights. This Interim Warrant shall not entitle its
         Holder to any of the rights of a stockholder 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 Common Stock a sufficient number of shares of
         Common Stock to provide for the issuance of Shares upon the exercise of
         this Interim Warrant. The Company further covenants that all 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 form of exercise hereof duly executed, accompanied by payment in
         full of the amount of the Interim Warrant Price in: (a) cash; (b)
         cashier's check; or (c) bank draft. Upon partial exercise hereof, a new
         Interim Warrant or Interim 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 Shares of Common Stock

                                       2
<PAGE>

         with respect to which this Interim Warrant shall not have been
         exercised. Upon each exercise of this Interim Warrant the Holder shall
         exercise this Interim Warrant and purchase the lesser of 100 Shares and
         the balance of Shares available for issuance 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, written notice of exercise, and payment for the
         number of Shares being acquired upon exercise of this Interim Warrant.
         The person entitled to receive the Shares issuable upon such exercise
         shall be treated for all purposes as the Holder of such Shares of
         record as of the close of business on such date. As promptly as
         practicable on or after such date, the Company shall issue and deliver
         to the person or persons entitled to receive the same a certificate or
         certificates for the number of full Shares of Common Stock issuable
         upon such exercise, together with cash in lieu of any fraction of a
         Share, as provided above.

7.       Additional Right to Convert Interim Warrant.

         a.       The holder of this Interim Warrant shall have the right to
                  require the Company to convert this Interim Warrant (the
                  "CONVERSION RIGHT") at any time prior to its expiration into
                  shares of Common Stock as provided for in this Section 7. Upon
                  exercise of the Conversion Right, the Company shall deliver to
                  the holder (without payment by the holder of any Interim
                  Warrant Price) the number of shares of Common Stock ("N")
                  determined based on the formula set forth below.

                  N  =  A - B
                        -----
                          C

                  For purposes of the Conversion Right, "A" is the aggregate
                  Fair Market Value for the Shares immediately prior to the
                  exercise of the Conversion Right, "B" is the aggregate
                  Exercise Price for the Shares in effect immediately prior to
                  the exercise of the Conversion Right, and "C" is the Fair
                  Market Value of one share of Common Stock immediately prior to
                  the exercise of the Conversion Right.

         b.       The Conversion Right may be exercised by the Holder, at any
                  time or from time to time, prior to its expiration, on any
                  business day by delivering a written notice in the form
                  attached hereto (the "CONVERSION NOTICE") to the Company at
                  the offices of the Company exercising the Conversion Right and
                  specifying (i) the total number of Shares the Holder will
                  purchase pursuant to such conversion and (ii) the name,
                  address and tax identification number of the entity or
                  individual in whose name the Shares are to be issued.

         c.       Upon exercise of the Conversion Right, (i) the Holder will
                  surrender the Interim Warrant, (ii) the Company will deliver
                  to the Holder a certificate or certificates for the number of
                  Shares issuable upon such conversion, together with cash, in
                  lieu of any fraction of a share, and (iii) the Company will
                  deliver to the Holder a new Interim Warrant representing the
                  number of shares, if any, with respect to which the Interim
                  Warrant shall not have been exercised.

         d.       "FAIR MARKET VALUE" means, with respect to the Company's
                  Common Stock, as of any date: (i) if the Common Stock is
                  listed or admitted to unlisted trading privileges on any
                  national securities exchange or is not so listed or admitted
                  but transactions in the Common Stock are reported on the
                  Nasdaq National Market, the reported closing price of the
                  Common Stock on such exchange or by the Nasdaq National Market
                  as of such date (or, if no shares were traded on such day, as
                  of the next preceding day on which there was such a trade); or
                  (ii) if the Common Stock is not so listed or admitted to
                  unlisted trading privileges or reported on the Nasdaq National
                  Market, and bid and asked prices therefor in the
                  over-the-counter market are reported by the Nasdaq system or
                  National Quotation Bureau, Inc. (or any comparable reporting
                  system), the mean of the closing bid and asked prices as of
                  such date, as so reported by the Nasdaq system, or, if not so
                  reported thereon, as reported by National Quotation Bureau,
                  Inc. (or such comparable reporting service); or (iii) if the
                  Common Stock is not so listed or admitted to unlisted trading
                  privileges, or reported on the Nasdaq National Market, and
                  such bid and asked prices are not so reported by the Nasdaq
                  system or National Quotation Bureau, Inc. (or any comparable
                  reporting service), such price as the Company's Board of
                  Directors determines in good faith in the exercise of its
                  reasonable discretion.

8.       Compliance with Securities Laws and Other Transfer Restrictions. The
         Holder of this Interim Warrant, by acceptance hereof, agrees,
         represents and Interim Warrants that this Interim Warrant and the
         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
         Shares, and that the Holder will not offer, sell or otherwise dispose
         of all or any part of this Interim Warrant or any Shares except under
         circumstances which will not result in a violation of the Securities
         Act of 1933, as amended (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 Shares are to be issued or
         so transferred, on 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
         its investment purpose and acceptance of the restrictions on transfer
         of the 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 at its expense (except for any
         transfer tax payable) will issue and exchange therefor Interim Warrants
         of like tenor and date representing in the aggregate the right to
         purchase such number of Shares of such 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 Paragraph shall be subject to and conditioned upon the compliance
         of any such subdivision with applicable state securities laws and with
         the Act.

                                       4

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
         Organization, 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.      Registration Rights. If, after the date one (1) year after the
         completion of the Company's initial public offering of common stock,
         the Company proposes to register under the Securities Act of 1933
         (except by a claim of exemption or registration statement on a form
         that does not permit the inclusion of shares by its security holders),
         other than (i) a registration relating solely to employee benefit plans
         or (ii) a registration relating solely to a Rule 145 Transaction, the
         Company will give written notice to all registered holders of Interim
         Warrants, and all registered holders of Shares, of its intention to do
         so and, on the written request of any such registered holders given
         within twenty (20) days after receipt of any such notice, the Company
         will use its best efforts to cause all such Shares, the registered
         holders of which shall have requested the registration or qualification
         thereof, to be included in such notification or registration statement
         proposed to be filed by the Company; provided, however, that nothing
         herein shall prevent the Company from, at any time, abandoning or
         delaying any such registration initiated by it. If any such
         registration shall be underwritten in whole or in part, the Company may
         require that the shares requested for inclusion pursuant to this
         Section 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 of
         the shares 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 stock offered by the
         Company, the number of shares otherwise to be included pursuant to this
         Section in the underwritten public offering may be reduced; provided,
         however, that any such required reduction shall be made among all
         persons other than the Company. Those shares which are thus excluded
         from the underwritten public offering shall be withheld from the market
         for a period, not to exceed 90 days, which the managing underwriter
         reasonably determines is necessary in order to effect the underwritten
         public offering. All expenses of such offering, except the fees of
         special counsel to such holders and brokers' commissions or
         underwriting discounts payable by such holders, shall be borne by the
         Company.

         a.       If and whenever the Company is required by the provisions of
                  Section 12 hereof to effect the registration of Shares under
                  the Securities Act, the Company will:

                                       5
<PAGE>

                  (1)      Prepare and file with the Securities and Exchange
                           Commission (the "COMMISSION") a registration
                           statement with respect to such securities, and use
                           its reasonable best efforts to cause such
                           registration statement to become and remain effective
                           for such period as may be reasonably necessary to
                           effect the sale of such securities;

                  (2)      prepare and file with the Commission such amendments
                           to such registration statement and supplements to the
                           prospectus contained therein as may be necessary to
                           keep such registration statement effective for such
                           period as may be reasonably necessary to effect the
                           sale of such securities;

                  (3)      furnish to the security holders participating in such
                           registration and to the underwriters of the
                           securities being registered such reasonable number of
                           copies of the registration statement, preliminary
                           prospectus, final prospectus and such other documents
                           as such underwriters may reasonably request in order
                           to facilitate the public offering of such securities;

                  (4)      use its reasonable best efforts to register or
                           qualify the securities covered by such registration
                           statement under such state securities or blue sky
                           laws of such jurisdictions as such participating
                           holders may reasonably request in writing within 30
                           days following the original filing of such
                           registration statement, except that the Company shall
                           not for any purpose be required to execute a general
                           consent to service of process or to qualify to do
                           business as a foreign corporation in any jurisdiction
                           wherein it is not so qualified;

                  (5)      notify the security holders participating in such
                           registration, promptly after it shall receive notice
                           thereof, of the time when such registration statement
                           has become effective or a supplement to any
                           prospectus forming a part of such registration
                           statement has been filed;

                  (6)      notify such holders promptly of any request by the
                           Commission for the amending or supplementing of such
                           registration statement or prospectus or for
                           additional information;

                  (7)      prepare and file with the Commission, promptly upon
                           the request of any such holders, any amendments or
                           supplements to such registration statement or
                           prospectus which, in the opinion of counsel for such
                           holders (and concurred in by counsel for the
                           Company), is required under the Securities Act or the

                  (8)      prepare and promptly file with the Commission and
                           promptly notify such holders of the filing of such
                           amendment or supplement to such registration
                           statement or prospectus as may be necessary to
                           correct any statements or omissions if, at the time
                           when a prospectus relating to such securities is
                           required to be delivered under the Securities Act,
                           any event shall have occurred as the result of which
                           any such prospectus or any other

                                       6
<PAGE>

                           prospectus as then in effect would include an untrue
                           statement of a material fact or omit to state any
                           material fact necessary to make the statements
                           therein, in the light of the circumstances in which
                           they were made, not misleading;

                           notice or obtain knowledge thereof, of the issuance
                           of any stop order by the Commission suspending the
                           effectiveness of such registration statement or the
                           initiation or threatening of any proceeding for that
                           purpose and promptly use its best efforts to prevent
                           the issuance of any stop order or to obtain its
                           withdrawal if such stop order should be issued;

                  (10)     not file any amendment or supplement to such
                           registration statement or prospectus to which a
                           majority in interest of such holders shall have
                           reasonably objected on the grounds that such
                           amendment or supplement does not comply in all
                           material respects with the requirements of the
                           Securities Act or the rules and regulations
                           thereunder, after having been furnished with a copy
                           thereof at least five business days prior to the
                           filing thereof, unless in the opinion of counsel for
                           the Company the filing of such amendment or
                           supplement is reasonably necessary to protect the
                           Company from any liabilities under any applicable
                           federal or state law and such filing will not violate
                           applicable law; and

                  (11)     at the request of any such holder, furnish on the
                           effective date of the registration statement and, if
                           such registration includes an underwritten public
                           offering, at the closing provided for in the

                           may reasonably request; and (ii) letters, dated such
                           respective dates, from the independent certified

                           (without limiting the generality of the foregoing)

         c.       The Company hereby indemnifies the holder of this Interim
                  Warrant and of any Shares, its officers and directors, and any
                  person who controls such Interim Warrant holder or such holder
                  of Shares within the meaning of Section 15 of the Securities
                  Act of 1933, against all losses, claims, damages and
                  liabilities caused by any untrue statement of a material fact
                  contained in any registration statement, prospectus,
                  notification or offering circular (and as amended or
                  supplemented if the Company shall have furnished any
                  amendments or supplements thereto) or any preliminary
                  prospectus or caused by any omission to state therein a
                  material fact required to be stated therein or necessary to
                  make the statements therein not misleading except insofar as
                  such losses, claims, damages or liabilities are caused by any
                  untrue statement or omission contained in information
                  furnished in writing to the Company by such Interim Warrant
                  holder or such holder of common stock expressly for use
                  therein, and each such holder by its acceptance hereof
                  severally agrees that it will indemnify and hold harmless the
                  Company and each of its officers who signs such registration
                  statement and each of its directors and each person, if any,
                  who controls the Company within the meaning of Section 15 of
                  the Securities Act of 1933 with respect to losses, claims,
                  damages or liabilities which are caused by any untrue
                  statement or omission contained in information furnished in
                  writing to the Company by such holder expressly for use
                  therein.

13.      Restriction on Transfer After a Public Offering. The Holder 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 Holder 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 undersigned will not, without the prior written consent of the
         Company and such underwriter, during the "Lockup Period" as defined
         herein: (a) sell, transfer or otherwise dispose of, or agree to sell,
         transfer or otherwise dispose of the Interim Warrant or any Shares
         beneficially owned by the undersigned during the Lockup Period; (b)
         sell, transfer or otherwise dispose of, or agree to sell, transfer or
         otherwise dispose of any options, rights or warrants to purchase the
         Interim Warrant or any Shares beneficially owned by the undersigned
         during the Lockup Period; or (c) sell or grant, or agree to sell or
         grant, options, rights or warrants with respect to the Interim Warrant
         or any of the Shares. 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) 18 months 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.

14.      Stop Transfer Order and Restrictive Legend. The Holder agrees that the
         Company may place a stop transfer order with its registrar and transfer
         agent (if any) covering all Shares. The Holder agrees that the Company
         may place one or more restrictive legends on any certificates
         evidencing the 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

                                       8
<PAGE>

                  securities law, and are subject to a subscription and
                  investment representation agreement. They may not be sold,
                  offered for sale, or transferred in the absence of either an
                  effective registration under the Securities Act of 1933, as
                  amended, and under the applicable state securities laws, or an
                  opinion of counsel for the Company that such transaction is
                  exempt from registration under 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 18 months following an initial public
                  offering of securities of the Company.

15.      Redemption Provision; Automatic Cancellation of Interim Warrant. If
         there is an effective registration statement covering the resale of the
         Shares and if the last sale price of the Company's common stock as
         reported by the principal securities exchange on which the common stock
         is listed or admitted to trading has averaged at least $5.00 per share
         for the 20 consecutive trading days ending at least five days prior to
         the date on which notice is given, the Company shall automatically have
         the right to redeem the Interim Warrant, by paying $0.01 per Share for
         the Interim Warrant, and shall deliver written notice to the Holder
         ("REDEMPTION NOTICE") of the Company's intention to redeem the Interim
         Warrant. The Holder shall have thirty (30) days from the date of the
         Redemption Notice ("REDEMPTION PERIOD") during which the Holder may
         exercise the Interim Warrant. If the Interim Warrant is not exercised
         during the Redemption Period, the Holder shall deliver the Interim
         Warrant to the Company for cancellation. Cancellation of the Interim
         Warrant shall be effective on the Company's books and records
         notwithstanding the Holder's failure to deliver the Interim Warrant to
         the Company for cancellation. The rights of the Company hereunder shall
         continue notwithstanding the Company's failure to complete any
         redemption for which a Redemption Notice has been provided.

16.      Postponement of Exercise. Notwithstanding anything herein to the
         contrary, the Company shall have the right to delay any exercise for a
         period of up to one hundred eighty (180) days for the purpose of: (a)
         ensuring the availability of an exemption under applicable securities
         laws for the issuance of the Shares to the Holder in light of the
         transactions by the Company in its securities; and/or (b) facilitating
         a distribution of the Company's securities. In either case, if the
         Company elects to delay any such exercise, the Company shall inform the
         Holder, in writing, of such delay and the terms of such delay. Any such
         delay shall not lead to any change in the Interim Warrant Price or the
         terms of the Interim Warrant and shall not extend the term of any
         Interim Warrant unless such delay would extend past the expiration date
         of such Interim Warrant. In such case, the expiration date shall be
         extended to thirty (30) days after the end of such delay.

17.      Miscellaneous. This Interim Warrant shall be governed by the laws of
         the State of Minnesota without regard to such state's conflict 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

                                       9

         certified mail, return receipt requested, or by overnight delivery
         service to the address furnished to the Company in writing by the last

         the Company in writing.

         interest therein, without Secured Party's prior written consent.

         b. The risk of injury to or loss of the Collateral shall rest solely
         upon Debtor, and such loss, injury or destruction shall not release
         Debtor from any of the Obligations.

         4. Events Of Default. Any of the following events shall be an Event of
Default:

         a. Debtor's failure to pay all amounts outstanding under the Interim
         Notes on or before the Maturity Date (as defined in the Interim Notes).

         b. Debtor's failure to pay all amounts outstanding as Bank Debt on or
         before the Maturity Date (as defined in the agreements documenting the
         Bank Debt).

         c. Debtor fails to observe or perform any covenant, condition, or
         agreement to be observed or performed pursuant to the terms hereof
         which materially and adversely affects any Lender.

         5. Appointment of Agent. Upon an Event of Default, each of the Lenders
hereby designates and appoints the Agent, and each of the Lenders hereby
irrevocably authorizes the Agent to take such action on their behalf under the
provisions of this Agreement and to exercise such powers as are set forth herein
or therein, together with such other powers as are incidental thereto. The Agent
agrees to act as such on the express terms and conditions contained in this
Agreement. Notwithstanding the use of the defined term "Agent," it is expressly
understood and agreed that the Agent shall not have any fiduciary
responsibilities to any Lender by reason of this Agreement and that the Agent is
merely acting as the representative of the Lenders with only those duties as are
expressly set forth in this Agreement. In its capacity as the Lenders'
contractual representative, the Agent: (i) does not assume any fiduciary duties
to any of the Lenders; and (ii) is acting as an independent contractor, the
rights and duties of which are limited to those expressly set forth in this
Agreement. Each of the Lenders agrees to assert no claim against the Agent on
any agency theory or any other theory of liability for breach of fiduciary duty,
all of which claims each Lender waives.

         6. Specific Remedies. Upon the occurrence of any Event of Default,
Agent shall have, in addition to, other rights given by law or in this
Agreement, the Interim Notes and the documentation governing the Bank Debt, all
of the rights and remedies with respect to the Collateral of a secured party
under the Code.

         7. Powers and Duties. The Agent shall have and may exercise such powers
under this Agreement as are specifically delegated to the Agent by the terms
hereof, together with such powers as are reasonably incidental thereto. The
Agent shall have no implied duties to the Lenders, or any obligation to the
Lenders to take any action hereunder, except any action specifically required by
this Agreement or by the written agreement of the remainder of the Lenders. The
Agent shall not take any action which is in conflict with any provisions of
applicable law or of this Agreement or any instructions signed by the remainder
of the Lenders and agreed to by the Agent.

         8. Authorization to execute Documents. Upon notice from the remaining
Lenders, the Agent shall be authorized to and shall execute and deliver such
documents or agreements and shall deliver to the Debtor or shall accept delivery
from the Debtor of such documents or agreements as are reasonably necessary to
carry out the terms of this Agreement after an Event of Default.

         9. Direction. The Agent shall take only such action with respect to the
Collateral directed in writing by the remaining Lenders and agreed to by the
Agent. Notwithstanding the foregoing, the Agent shall not be obligated to take
any such action: (i) which is in conflict with any provisions of applicable law
or of this Agreement; or (ii) with respect to which the Agent, in its opinion,
shall not have been provided adequate security and indemnity against the costs,
expenses and liabilities that may be incurred by it as a result of compliance
with such direction. Under no circumstances shall the Agent be liable for
following the written direction of the remainder of the Lenders.

         10. The Collateral Account. Upon an Event of Default, the Agent shall
establish and maintain at its principal office an interest-bearing account that
shall be entitled the "Redline Collateral Account." All moneys received by the
Agent with respect to Collateral after an Event of Default shall be deposited in
the Account and thereafter shall be held, applied and/or disbursed by the Agent
in accordance with Section 11 hereof. In no event shall moneys other than
proceeds of Collateral (and interest thereon) be deposited in the Collateral
Account. The Collateral Account at all times shall be subject to the exclusive
dominion and control of the Agent.

         11. Application of Moneys. All moneys held by the Agent in the
Collateral Account shall be distributed by the Agent at such times as are agreed
to by the remaining Lenders and the Agent as follows:

                  FIRST: To the Agent in an amount equal to the reasonable
                  expenses of the Agent in performing its duties hereunder and
                  that are unpaid as of such date, and to any Lender that has
                  theretofore advanced or paid any such expenses in

                                      C-6
<PAGE>

                  an amount equal to the amount thereof so advanced or paid by
                  such Lender prior to such date;

                  SECOND: To the Lenders and the Agent in an amount equal to the
                  total amount of the Obligations owed to each Lender and the
                  Agent. In the event the moneys are not equal to or more than
                  the amount of the Obligations owed to each Lender and the
                  Agent, then to the Lenders and the Agent in an amount equal to
                  the Agent's and each remaining Lender's Pro-Rata Share; and

                  THIRD: Any surplus remaining after payment in full in cash of
                  all the Agent's expenses and all of the Obligations shall be
                  paid to the Debtor, or to whomever may be lawfully entitled to
                  receive the same, or as a court of competent jurisdiction may
                  direct

Notwithstanding the foregoing, except for any surplus under clause THIRD above,
the Agent shall not be required (unless agreed to by the remaining Lenders and
the Agent) to make a distribution if the balance in the Collateral Account
available for distribution is less than $1,000. The Agent shall not be
responsible for any Lender's application (or order of application) of payments
received by such Lender from the Agent hereunder to the Obligations owing to
such Lender.

         12. Information from Lenders. Each of the Lenders hereby agrees,
promptly upon request by the Agent, to provide to the Agent in writing such
information regarding the Obligations held by such Lender as may be reasonably
required by the Agent at any time to determine such Lender's Pro Rata Share or
to calculate distributions to such Lender from the Collateral Account. Each
Lender shall notify the Agent in writing promptly following the repayment in
full or termination of all Obligations owing to such Lender.

         13. Limitation on Agent's Duties in Respect of Collateral. Other than
the Agent's duties set forth in this Agreement as to the custody of Collateral
and the proceeds thereof received by the Agent hereunder and thereunder and the
accounting to the Debtor and the Lenders therefore, the Agent shall have no duty
to the Debtor or the remaining Lenders with respect to any Collateral in its
possession or control or in the possession or control of its agent or nominee,
any income thereon, or the preservation of rights against prior parties or any
other rights pertaining thereto.

         14. Agent's Reimbursement and Indemnification. The Lenders agree to
reimburse and indemnify the Agent ratably in proportion to their respective Pro
Rata Shares as of the date of any demand by the Agent with respect thereto: (i)
for any reasonable expenses incurred by the Agent, on behalf of the remaining
Lenders, in connection with the preservation or protection of the Collateral or
the validity, perfection or priority of the enforcement of this Agreement
against the Debtor; and (ii) for any liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever which may be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of this Agreement.

<PAGE>

         15. Rights as a Lender. Notwithstanding that the Agent is acting as the
Agent hereunder, the Agent in its individual capacity shall have the same rights
and powers hereunder as any Lender and may exercise the same as though it were
not the Agent.

         16. Successor Agent. The Agent may resign at any time by giving not
less than thirty days' prior written notice thereof to the remaining Lenders and
the Debtor and the Agent may be removed at any time with or without cause by
written notice received by the Agent from the remaining Lenders. Upon any such
resignation or removal, the remaining Lenders shall have the right to appoint,
on behalf of the Lenders, a successor Agent. If no successor Agent shall have
been so appointed by the Lenders and shall have accepted such appointment within
thirty days after the retiring Agent's giving notice of resignation, then the
retiring Agent may appoint, on behalf of the Lenders, a successor Agent. Upon
the acceptance of any appointment as the Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. After any
retiring Agent's resignation hereunder as Agent, the provisions of this
Agreement shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as the Agent hereunder.

         17. Choice of Law and Venue. The validity of this Agreement, its
construction, interpretation, and enforcement, and the rights of the parties
hereto with respect to all matters arising hereunder or related hereto shall be
determined under, governed by, and construed in accordance with the laws of the
state of Minnesota, without giving effect to its conflict of laws principles.
The parties agree that all actions or proceedings arising in connection with
this agreement shall be tried and litigated only in the state and federal courts
located in Hennepin County, Minnesota.

         18. General Provisions.

         a. Effectiveness. With respect to each Lender, this Agreement shall be
         binding and deemed effective when executed by such Lender.

         b. Successors and Assigns. This Agreement shall bind and inure to the
         benefit of the respective successors and assigns of each of the
         parties; provided, however, that neither Debtor nor any of the Lenders
         may assign this Agreement or any rights or duties hereunder without the
         other party's prior written consent and any prohibited assignment shall
         be absolutely void.

         c. Section Headings. Headings and numbers have been set forth herein
         for convenience only. Unless the contrary is compelled by the context,
         everything contained in each Section applies equally to this entire
         Agreement.

         d. Severability of Provisions. Each provision of this Agreement shall
         be severable from every other provision of this Agreement for the
         purpose of determining the legal enforceability of any specific
         provision.

                                      C-8
<PAGE>

         e. Amendments in Writing. A writing signed by each Lender and Debtor
         can only amend this Agreement.

         f. Counterparts; Facsimile Execution. This Agreement may be executed in
         any number of counterparts and by different parties on separate
         counterparts, each of which, when executed and delivered, shall be
         deemed to be an original, and all of which, when taken together, shall
         constitute but one and the same Agreement. Delivery of an executed
         counterpart of this Agreement by facsimile shall be equally as
         effective as delivery of a manually executed counterpart of this
         Agreement. Any party delivering an executed counterpart of this
         Agreement by facsimile also shall deliver a manually executed
         counterpart of this Agreement but the failure to deliver a manually
         executed counterpart shall not affect the validity, enforceability, and
         binding effect of this Agreement.

         g. Notices. All notices, demands, and requests that either party is
         required or elects to give to the other shall be in writing and shall
         be delivered personally or sent by registered or certified mail, first
         class postage prepaid, to the business address of the Lenders, as
         indicated in the Debtor's records, or to the principal office of the
         Debtor, whichever is applicable.

         h. Termination. This Agreement shall terminate as to a Lender after
         payment and performance of all Obligations owed to such Lender. At such
         time such Lender shall execute documents necessary to terminate its
         security interest granted hereunder. At such time, as the payment and
         performance of all Obligations of the final Lender have been satisfied,
         such Lender shall execute and deliver to Debtor a termination of all
         remaining security interests granted by Debtor hereunder.

         i. Integration. This Agreement reflects the entire understanding of the
         parties with respect to the transactions contemplated hereby and shall
         not be contradicted or qualified by any other agreement, oral or
         written, before the date hereof. In the event of a conflict between the
         terms of this Agreement and any other agreement or document, the terms
         of this Agreement shall control.
