            4.1 Representations and Warranties of the Company. The Company

            qualified to do business and is in good standing in all states where
            such qualification is necessary, except for those jurisdictions in

            material adverse effect on the Company's financial condition,
            results of operations or business.

                  (b) Authority. The execution and delivery by the Company of

                  (c) Binding Effect. This Agreement, the Note and the Warrants

            Company's (i) Annual Report on Form 10-KSB for the fiscal year ended

                  (f) Securities Matters. Subject to the accuracy of the
            representations of the Purchaser set forth in Section 3.2 hereof,
            the offer, sale and issuance of the Securities as contemplated by
            this Agreement are exempt from the registration requirements of the
            Securities Act of 1933 as amended (the "Securities Act"). The
            Company has complied and will comply with all applicable state "blue
            sky" or securities laws in connection with the offer, sale and
            issuance of the Securities as contemplated by this Agreement.

            4.2 Representations and Warranties of the Purchaser. The Purchaser
      represents and warrants that as of the date of the execution of this
      Agreement:

                  (a) Authorization. This Agreement constitutes a valid and
            legally binding obligation of the Purchaser.

                  (b) Investment Representations. (i) The Purchaser has received
            and reviewed the SEC Documents and the Purchaser or the Purchaser's
            designated representatives have concluded a satisfactory due
            diligence investigation of the Company and have had an opportunity
            to review the documents provided by the Company and to have all of
            their questions related thereto satisfactorily answered.

                        (ii) The Purchaser understands the fundamental risks of
                  the Securities; has determined that he/she/it can reasonably
                  benefit from the investment based upon net worth, income,
                  overall investment objectives and portfolio structure; that
                  the Purchaser's overall commitment to investments which are
                  not readily marketable is not disproportionate to the
                  Purchaser's net worth, and that the Securities will not cause
                  such overall commitment to become excessive; and, that the
                  Purchaser is able to bear the economic risk of the Securities,
                  including the loss of the entire value of its investment.
                  Additionally, the Purchaser understands that that there are
                  restrictions on the Purchaser's right to liquidate the
                  Securities.


                                       3

                        (iii) The Purchaser has reviewed the Risk Factors
                  sections included in the SEC Documents, and understands the
                  Risk Factors describing the fact that the Company (a) has
                  substantial liabilities, (b) may not be able to obtain
                  sufficient funds to grow its business and the subsequent
                  financing may be on terms adverse to the Securities and (c) is
                  currently not profitable.

                        (iv) The Purchaser (or its members and/or officers) has
                  previously invested in unregistered securities and has
                  sufficient financial and investing expertise to evaluate and
                  understand the risks of the Securities.

                        (v) The Purchaser has received from the Company, and is
                  relying on, no representations or projections (except as set
                  forth in this Agreement or the SEC Documents) with respect to
                  the Company's business and prospects.

                        (vi) The Purchaser is an "accredited investor" within
                  the meaning of Regulation D under the Securities Act.

                        (vii) The Purchaser is acquiring the Securities for
                  investment purposes only without intent to distribute the
                  same, and acknowledges that the Securities have not been
                  registered under the Securities Act and applicable state
                  securities laws, and accordingly, constitutes "restricted
                  securities" for purposes of the Securities Act and such state
                  securities laws.

                        (viii) The Purchaser acknowledges that it will not be
                  able to transfer the Securities except upon compliance with
                  the registration requirements of the Securities Act and
                  applicable state securities laws or exemptions therefrom.

                        (ix) The certificates and/or instruments evidencing the
                  Securities will contain a legend to the foregoing effect.

      5. REGISTRATION RIGHTS. The initial holder of the Note and Warrants (and
certain assignees thereof) shall have registration rights as follows:

            (a) Participation in Registered Offerings. If the Company proposes
      or is required to register any of its shares or other equity securities
      for public sale for cash under the Securities Act (other than on Forms S-4
      or S-8 or similar registration forms), it will at each such time or times
      give written notice to the Purchaser of its intention to do so. Upon the
      written request of the Purchaser given within twenty (20) days after
      receipt of any such notice, the Company shall use its best efforts to
      cause to be included in such registration any Conversion Shares or
      Registrable Securities (together, "Registrable Securities") held by the
      Purchaser requested to be registered; provided, that if the managing
      underwriter advises that less than all of the shares requested to be
      registered should be offered for sale so as not materially and adversely
      to affect the price or salability of such offering being registered by the


                                       4
<PAGE>

      Company, the Purchaser (but not the Company to the extent it desires to
      include shares for its own account) shall reduce the number of its
      Registrable Securities to be included in the registration statement as
      required by the underwriter to the extent requisite of all prospective
      sellers of the securities proposed to be registered (other than the
      Company) on a pro rata basis according to the amounts of securities
      proposed to be registered by all prospective sellers to permit the sale or
      other disposition (in accordance with the intended method of disposition
      thereof as aforesaid) by the prospective seller or sellers of the
      securities so registered. The registration requested pursuant to this
      Section 5(a) is referred to herein as the "Piggyback Registration".

            (b) Obligations of Purchaser. It shall be a condition precedent to
      the obligation of the Company to register any Registrable Securities
      pursuant to this Section 5 that the Purchaser shall furnish to the Company
      such information regarding the Registrable Securities held and the
      intended method of disposition thereof and other information concerning
      the Purchaser as the Company shall reasonably request and as shall be
      required in connection with the registration statement to be filed by the
      Company. If after a registration statement becomes effective the Company
      advises the Purchaser that the Company considers it appropriate to amend
      or supplement the applicable registration statement, the Purchaser shall
      suspend further sales of the Registrable Securities until the Company
      advises the Purchaser that such registration statement has been amended or
      supplemented.

            (c) Registration Proceedings. Whenever the Company is required by
      the provisions of this Section 5 to effect the registration of the
      Registrable Securities under the Securities Act, the Company shall:

                  (i) Prepare and promptly file with the SEC a registration
            statement with respect to such securities and use its best efforts
            to cause such registration statement to become effective within 90
            days of filing and remain effective;

                  (ii) Prepare and file with the SEC such amendments to such
            registration statement and supplements to the prospectus contained
            therein as may be necessary to keep such registration statement
            effective;

                  (iii) Furnish to the Purchaser 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;

                  (iv) Use its 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 the Purchaser
            may reasonably request within twenty (20) 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
<PAGE>

                  (v) Notify the Purchaser, 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;

                  (vi) Notify the Purchaser promptly of any request by the SEC
            for the amending or supplementing of such registration statement or
            prospectus or for additional information; and

                  (vii) Prepare and promptly file with the SEC and promptly
            notify the Purchaser 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 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 light of the circumstances in which they were made, not
            misleading. Notwithstanding any provision herein to the contrary,
            the Company shall not be required to amend, supplement, or update a
            prospectus contained in any registration statement if to do so would
            result in an unduly burdensome expense to the Company.

            (d) Expenses. With respect to the inclusion of the Registrable
      Securities in a registration statement pursuant to this Section 5, all
      registration expenses, fees, costs and expenses of and incidental to such
      registration, shall be borne by the Company; provided, however, that
      Purchaser shall bear its own professional fees and pro rata share of the
      underwriting discounts and commissions. The fees, costs and expenses of
      registration to be borne by the Company shall include, without limitation,
      all registration, filing, and printing expenses, fees and disbursements of
      counsel and accountants for the Company, fees and disbursements of counsel
      for the underwriter or underwriters of such securities (if the Company
      and/or selling security holders are required to bear such fees and
      disbursements), and all legal fees and disbursements and other expenses of
      complying with state securities or Blue Sky laws of any jurisdiction in
      which the securities to be offered are to be registered or qualified.

            (e) Indemnification of the Purchaser. Subject to the conditions set
      forth below, in connection with any registration of the Registrable
      Securities pursuant to this Section 5, the Company agrees to indemnify and
      hold harmless the Purchaser, any underwriter for the offering and each of
      their officers and directors and agents and each other person, if any, who
      controls Purchaser or their underwriter (each, a "Purchaser Indemnified
      Party"), within the meaning of Section 15 of the Securities Act, as
      follows:


                                       6
<PAGE>

                  (i) Against any and all loss, claim, damage and expense
            whatsoever arising out of or based upon (including, but not limited
            to, any and all expense whatsoever reasonably incurred in
            investigating, preparing or defending any litigation, commenced or
            threatened, or any claim whatsoever based upon) any untrue or
            alleged untrue statement of a material fact contained in any
            preliminary prospectus (if used prior to the effective date of the
            registration statement), the registration statement or the
            prospectus (as from time to time amended and supplemented), or in
            any application or other document executed by the Company or based
            upon written information furnished by the Company filed in any
            jurisdiction in order to qualify the Company's securities under the
            securities laws thereof, or the omission or alleged omission
            therefrom of a material fact required to be stated therein or
            necessary to make the statements therein not misleading, or any
            other violation of applicable federal or state statutory or
            regulatory requirements or limitations relating to action or
            inaction by the Company in the course of preparing, filing, or
            implementing such registered offering; provided, however, that the
            indemnity agreement contained in this section shall not apply to any
            loss, claim, damage, liability or action arising out of or based
            upon any untrue or alleged untrue statement or omission made in
            reliance upon and in conformity with any information furnished in
            writing to the Company by or on behalf of the Purchaser expressly
            for use in connection therewith or arising out of any action or
            inaction of the Purchaser;

                  (ii) Subject to the proviso contained in Subsection (i) above,
            against any and all loss, liability, claim, damage and expense
            whatsoever to the extent of the aggregate amount paid in settlement
            of any litigation, commenced or threatened, or of any claim
            whatsoever based upon any untrue statement or omission (including,
            but not limited to, any and all expense whatsoever reasonably
            incurred in investigating, preparing or defending against any such
            litigation or claim) if such settlement is effected with the written
            consent of the Company; and

                  (iii) In no case shall the Company be liable under this
            indemnity agreement with respect to any claim made against any
            Purchaser Indemnified Party unless the Company shall be notified, by
            letter or by facsimile confirmed by letter, of any action commenced
            against such Purchaser Indemnified Party, promptly after such person
            shall have been served with the summons or other legal process
            giving information as to the nature and basis of the claim. The
            failure to so notify the Company, if prejudicial in any material
            respect to the Company's ability to defend such claim, shall relieve
            the Company from its liability to the indemnified person under this
            Section 5(e), but only to the extent that the Company was
            prejudiced. The failure to so notify the Company shall not relieve
            the Company from any liability which it may have otherwise than on
            account of this indemnity agreement. The Company shall be entitled
            to participate at its own expense in the defense of any suit brought
            to enforce any such claim, but if the Company elects to assume the
            defense, such defense shall be conducted by counsel chosen by it,


                                       7
<PAGE>

            provided such counsel is reasonably satisfactory to the Purchaser
            Indemnified Party in any suit so brought. In the event the Company
            elects to assume the defense of any such suit and retain such
            counsel, the Purchaser Indemnified Party in the suit shall, after
            the date they are notified of such election, bear the fees and
            expenses of any counsel thereafter retained by them, as well as any
            other expenses thereafter incurred by them in connection with the
            defense thereof; provided, however, that if the Purchaser
            Indemnified Party reasonably believes that there may be available to
            it any defense or counterclaim different than those available to the
            Company or that representation of the Purchaser Indemnified Party by
            counsel for the Company presents a conflict of interest for such
            counsel, then the Purchaser Indemnified Party shall be entitled to
            defend such suit with counsel of its own choosing and the Company
            shall bear the fees, expenses and other costs of such separate
            counsel.

            (f) Indemnification of the Company. The Purchaser agrees to
      indemnify and hold harmless the Company, each underwriter for the
      offering, and each of their officers and directors and agents and each
      other person, if any, who controls the Company and the underwriter within
      the meaning of Section 15 of the Securities Act and any other stockholder
      selling securities against any and all such losses, liabilities, claims,
      damages and expenses as are indemnified against by the Company under
      Section 5(f) (i), (ii) and (iii) above; provided, however, that such
      indemnification by Purchaser hereunder shall be limited to any losses,
      liabilities, claims, damages, or expenses to the extent caused by any
      untrue statement of a material fact or omission of a material fact
      (required to be stated therein or necessary to make statements therein not
      misleading), if any made (or in settlement of any litigation effected with
      the written consent of such Purchasers, alleged to have been made) in any
      preliminary prospectus, the registration statement or prospectus or any
      amendment or supplement thereof or in any application or other document in
      reliance upon, and in conformity with, written information furnished in
      respect of such Purchaser by or on behalf of such Purchaser expressly for
      use in any preliminary prospectus, the registration statement or
      prospectus or any amendment or supplement thereof or in any such
      application or other document or arising out of any action or inaction of
      such Purchaser in implementing such registered offering. In case any
      action shall be brought against the Company, or any other person so
      indemnified, in respect of which indemnity may be sought against any
      Purchaser, such Purchaser shall have the rights and duties given to the
      Company, and each other person so indemnified shall have the rights and
      duties given to Purchaser, by the provisions of Section 5(f). The person
      indemnified agrees to notify the Purchaser promptly after the assertion of
      any claim against the person indemnified in connection with the sale of
      securities.


                                       8
<PAGE>

            (g) Contribution. If the indemnification provided for in Sections
      5(e) and 5(f) above are unavailable or insufficient to hold harmless an
      indemnified party in respect of any losses, claims, damages or liabilities
      (or actions in respect thereof) referred to therein, then each
      indemnifying party shall contribute to the amount paid or payable by such
      indemnified party as a result of such losses, claims, damages or
      liabilities (or actions in respect thereof) in such proportion as is
      appropriate to reflect the relative fault of the indemnified party, on one
      hand, and such indemnifying party, on the other hand, in connection with
      the statements or omissions which resulted in such losses, claims,
      damages, or liabilities (or actions in respect thereof). The relative
      fault shall be determined by reference to, among other things, whether the
      untrue or alleged untrue statement of a material fact or the omission or
      alleged omission to state a material fact relates to information supplied
      by the indemnified party, on one hand, or such indemnifying party, on the
      other hand, and the parties' relative intent, knowledge, access to
      information and opportunity to correct or prevent such statement or
      omission. No person who has committed fraudulent misrepresentation (within
      the meaning of the Securities Act) shall be entitled to contribution from
      any person who was not guilty of such fraudulent misrepresentation. The
      amount paid or payable by an indemnified party as a result of the losses,
      claims, damages or liabilities (or actions in respect thereof) referred to
      above in this Section shall be deemed to include any legal or other
      expenses reasonably incurred by such indemnified party in connection with
      investigating or defending any such action or claim.

            (h) Assignment of Registration Rights. The right to have the Company
      register Registrable Securities pursuant to this Warrant shall be
      automatically assignable to any transferee of all or any portion of the
      Registrable Securities if: (a) the Purchaser agrees in writing with the
      transferee or assignee to assign such rights, and a copy of such agreement
      is furnished to the Company within a reasonable time after such
      assignment, (b) the Company is, within a reasonable time after such
      transfer or assignment, furnished with written notice of (i) the name and
      address of such transferee or assignee, and (ii) the securities with
      respect to which such registration rights are being transferred or
      assigned, (c) following such transfer or assignment, the further
      disposition of such securities by the transferee or assignee is restricted
      under the 1933 Act and applicable state securities laws and, (d) at or
      before the time the Company receives the written notice contemplated by
      clause (b) of this sentence, the transferee or assignee agrees in writing
      with the Company to be bound by all of the provisions contained herein
      (the foregoing a "Permitted Transferee").

      6. MISCELLANEOUS.

            6.1 Confidentiality.

                  (a) The Purchaser agrees to keep confidential any and all
            non-public information delivered or made available to the Purchaser
            by the Company except for disclosures, as necessary, made by the
            Purchaser to the Purchaser's officers, directors, employees, agents,
            counsel and accountants each of whom shall be notified by the
            Purchaser of this confidentiality covenant and for whom the
            Purchaser shall be liable in the event of any breach of this
            covenant by any such individual or individuals; provided, however,
            that nothing herein shall prevent the Purchaser from disclosing such
            information (a) upon the order of any court or administrative
            agency, (b) upon the request or demand of any regulatory agency or
            authority having jurisdiction over the Purchaser, (c) which has been
            publicly disclosed or (d) to any of its members provided that any
            such members agree in writing (with a copy provided to the Company)


                                       9
<PAGE>

            to be bound by confidentiality provisions in form and substance
            substantially as are contained herein. In the event of a mandatory
            disclosure as described in clause (a) and/or (b) of the preceding
            sentence, the Purchaser shall promptly notify the Company in writing
            of any applicable order, request or demand for such information,
            cooperate with the Company if and to the extent that the Company
            elects to seek an appropriate protective order or other relief from
            such order, request, or demand, and disclose only the minimal amount
            of information ultimately required to be disclosed. The Purchaser
            shall not use for its own benefit, nor permit any other person to
            use for such person's benefit, any of the Company's non-public
            information including, without limitation, in connection with the
            purchase and/or sale of the Company's securities.

                  (b) The Company shall in no event disclose non-public
            information to the Purchaser, advisors to or representatives of the
            Purchaser unless prior to disclosure of such information the Company
            marks such information as "Non-Public Information - Confidential"
            and provides the Purchaser, such advisors and representatives with
            the opportunity to accept or refuse to accept such non-public
            information for review. The Company may, as a condition to
            disclosing any non-public information hereunder, require the
            Purchaser's advisors and representatives to enter into a
            confidentiality agreement in form reasonably satisfactory to the
            Company and the Purchaser.

                  (c) Nothing herein shall require the Company to disclose
            non-public information to the Purchaser or its advisors or
            representatives, and the Company represents that it does not
            disseminate non-public information to any Purchasers who purchase
            stock in the Company in a public offering, to money managers or to
            securities analysts.

            6.2 Legends. To the extent applicable, each note, certificate or
      other document evidencing the Securities to be purchased and sold pursuant
      to this Agreement shall be endorsed with the legends set forth below, and
      the Purchaser on behalf of itself and each holder of the Securities
      covenants that, except to the extent such restrictions are waived by the
      Company, it shall not transfer the Securities without complying with the
      restrictions on transfer described in the legends endorsed on such
      Securities:

                  (a) The following legend under the Securities Act:

                  "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                  UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED,
                  AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, OR
                  HYPOTHECATED ABSENT AN EFFECTIVE REGISTRATION THEREOF UNDER
                  SUCH ACT OR COMPLIANCE WITH RULE 144 PROMULGATED UNDER SUCH
                  ACT, OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL,
                  IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE COMPANY
                  AND ITS COUNSEL AND FROM ATTORNEYS REASONABLY ACCEPTABLE TO
                  THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT
                  REQUIRED."

<PAGE>

                  (b) If required by the authorities of any state in connection
            with the issuance or sale of the Securities, the legend required by
            such state authority.

                  (c) The legend set forth above shall be removed from the
            Securities and the Company shall within two (2) business days issue
            a certificate without such legend to the holder of the Securities
            upon which it is stamped, if, unless otherwise required by state
            securities laws, (i) in connection with a sale transaction, provided
            the Securities are registered under the Securities Act or (ii) in
            connection with a sale transaction, after such holder provides the
            Company with an opinion of counsel, which opinion shall be in form,
            substance and scope customary for opinions of counsel in comparable
            transactions, to the effect that a public sale, assignment or
            transfer of the Securities may be made without registration under
            the Securities Act. The legend set forth above shall be removed from
            the Securities and the Company shall issue replacement Securities
            without such legend to the holder of the Securities immediately upon
            the registration of the Securities under the Securities Act.

            6.3 Fees and Expenses.

                  (a) The Company shall pay a structuring/finder's fee in an
            amount equal to 15 points, or $18,750 for a total investment of
            $125,000. The Company agrees that such fee may be deducted from the
            gross amount of the Loan Amount at Closing.

                  (b) The Company shall reimburse Purchaser for its reasonable
            legal fees and expenses in connection with the purchase of the
            Securities. The Company shall be responsible for all of its fees and
            expenses in connection with this transaction.

            6.4 Assignability; Successors. The provisions of this Agreement
      shall inure to the benefit of and be binding upon the permitted successors
      and assigns of the parties hereto.

            6.5 Survival. All agreements, covenants, representations and
      warranties made by the Company or by the Purchaser herein shall survive
      the execution and delivery of this Agreement.

            6.6 GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED ACCORDING TO
      THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO THE PRINCIPLES
      THEREOF RELATING TO CONFLICTS OF LAWS.

            6.7 Counterparts: Headings. This Agreement may be executed in
      several counterparts, each of which shall be deemed an original, but such
      counterparts shall together constitute but one and the same agreement. The
      descriptive headings in this Agreement are inserted for convenience of
      reference only and shall not affect the construction of this Agreement.

            6.8 Legal Representation.

                  (a) Each party hereto represents and warrants that it has
            carefully read this Agreement and knows the contents hereof and that
            it has signed this Agreement freely and voluntarily and that each
            party has obtained independent counsel in reviewing this document
            and further acknowledges that the law firm of Gallagher, Briody &
            Butler has memorialized the within Agreement and has provided legal
            advice solely to the Company with respect to this Agreement.

                  (b) The Purchaser was provided the opportunity to retain
            individual counsel, and has retained or waived the right to retain
            individual counsel to review this Agreement.

            6.9 Entire Agreement, Amendments. This Agreement and the Exhibits
      contain the entire understanding of the parties with respect to the
      subject matter hereof, and supersede all other representations and
      understandings, oral or written, with respect to the subject matter

      Any such amendment, modification, alteration, waiver or consent shall be
      effective only in the specific instance and for the specific purpose for
      which given.

            6.11 Severability. Whenever possible, each provision of this
      Agreement shall be interpreted in such manner as to be effective and valid
      under applicable law, but if any provision of this Agreement shall be
      prohibited by or invalid under applicable law, such provision shall be
      ineffective to the extent of such prohibition or invalidity, without
      invalidating the remainder of such provision or the remaining provisions
      of this Agreement.

            6.12 Maximum Interest. It is expressly stipulated and agreed to be
      the intent of the Company and the Purchaser at all times to comply with
      the applicable law governing the maximum rate of interest payable on or in
      connection with all indebtedness and transactions hereunder (or applicable
      United States federal law to the extent that it permits Purchaser to
      contract for, charge, take, reserve or receive a greater amount of
      interest). If the applicable law is ever judicially interpreted so as to
      render usurious any amount of money or other consideration called for
      hereunder, or contracted for, charged, taken, reserved or received with
      respect to any loan or advance hereunder, or if acceleration of the
      maturity of the Note results in the Company's having paid any interest in
      excess of that permitted by law, then it is the Company's and the
      Purchaser's express intent that all excess cash amounts theretofore
      collected by Purchaser be credited on the principal balance of the Note
      (or if the Note has been or would thereby be paid in full, refunded to the
      Company), and the provisions of this Agreement immediately be deemed
      reformed and the amounts thereafter collectible hereunder reduced, without
      the necessity of the execution of any new document, so as to comply with
      the applicable law, but so as to permit the recovery of the fullest amount
      otherwise called for hereunder. The right to accelerate maturity of the
      Note does not include the right to accelerate any interest which has not
      otherwise accrued on the date of such acceleration, and the Purchaser does
      not intend to collect any unearned interest in the event of acceleration.

      hereunder or now or hereafter existing at law, in, equity, by statute or
      otherwise.

      4. CHANGES; PARTIES. This Note can only be changed by an agreement in

successors and assigns.

      5. WAIVER OF PRESENTMENT. The Company hereby waives presentment, demand,
notice, protest and all other demands and notices in connection with the
delivery, acceptance, performance, default or enforcement of this Note.

      6. MAXIMUM RATE OF INTEREST. It is expressly stipulated and agreed to be
the intent of the Company and Holder at all times to comply with the applicable
law governing the maximum rate of interest payable on or in connection with all
indebtedness and transactions hereunder (or applicable United States federal law
to the extent that it permits Holder to contract for, charge, take, reserve or
receive a greater amount of interest). If the applicable law is ever judicially
interpreted so as to render usurious any amount of money or other consideration
called for hereunder, or contracted for, charged, taken, reserved or received
with respect to any loan or advance hereunder, or if acceleration of the
maturity of this Note or the indebtedness hereunder or if any prepayment by the


                                       2
<PAGE>

Company results in the Company's having paid any interest in excess of that
permitted by law, then it is the Company's and Holder's express intent that all
excess cash amounts theretofore collected by Holder be credited on the principal
balance of this Note (or if this Note has been or would thereby be paid in full,
refunded to the Company), and the provisions of this Note immediately be deemed
reformed and the amounts thereafter collectible hereunder reduced, without the
necessity of the execution of any new document, so as to comply with the
applicable law, but so as to permit the recovery of the fullest amount otherwise
called for hereunder. The right to accelerate maturity of this Note does not
include the right to accelerate any interest which has not otherwise accrued on
the date of such acceleration, and Holder does not intend to collect any
unearned interest in the event of acceleration.

      7. NO IMPLIED WAIVER. No failure or delay on the part of Holder in
exercising any right, power or privilege under this Note and no course of
dealing between the Company and Holder shall operate as a waiver thereof. No
single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise of any right, power or privilege Holder
would otherwise have. No notice to, or demand on, the Company in any case shall
entitle the Company to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the right of Holder to any other or
further action in any circumstances without notice or demand.

      8. GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED ACCORDING TO THE LAWS
OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO THE PRINCIPLES THEREOF
RELATING TO CONFLICTS OF LAWS.
