                               LOANS AND INTEREST

         2.1 Loans. From and including the date of this Agreement and prior to
the Credit Termination Date, Lender may from time to time, in its sole
discretion and upon the terms and conditions set forth in this Agreement, make a
Loan or Loans, in an aggregate amount not to exceed $3,0000,000 (including the
outstanding principal of the Initial Loans), to Boundless. Each Loan made on or
after the Effective Date will be evidenced by a notation on Schedule I to the
Note, which shall state the date and amount of such Loan.

         2.2 Evidence of Indebtedness; Security. The Loans made by Lender to
Boundless hereunder shall be evidenced by a promissory note (a "Note") in the
form set forth in Exhibit A. As requests are made from time to time by Boundless
for an additional Loan, and such request is granted by Lender, then Schedule I
to the Note shall be amended by Lender and Boundless to

                                       3
<PAGE>

reflect the date and amount of such Loan, and a copy thereof delivered to
Boundless. The Note shall be secured by a Security Agreement, in the form of
Exhibit B attached hereto, and shall be guaranteed by each Subsidiary, pursuant
to a Guaranty, in the form of Exhibit C attached hereto.

         2.3 Interest Rate. Interest on the Loans shall be computed, at the rate
of ten percent (10%) per annum, for the actual number of days elapsed and on the
basis of a year consisting of 360 days, unless the maximum legal interest rate
would thereby be exceeded, in which event, to the extent necessary to avoid
exceeding such maximum rate, interest shall be computed on the basis of the
actual number of days elapsed in the applicable calendar year in which it
accrued. Interest shall be payable for the day a Loan is made but not for the
day of any payment on the amount paid if payment is received prior to noon
(local time) at the place of payment. If any payment of principal of or interest
on a Loan shall become due on a day which is not a Business Day, such payment
shall be made on the next succeeding Business Day and, in the case of a
principal payment, such extension of time shall be included in computing
interest in connection with such payment.

         2.4 Maximum Lawful Rate. This Agreement, the Loans and the other Loan
Documents are hereby limited by this Section 2.4. In no event, whether by reason
of acceleration of the maturity of the amounts due hereunder or otherwise, shall
interest and fees contracted for, charged, received, paid or agreed to be paid
to Lender exceed the maximum amount permissible under such applicable law. If,
from any circumstance whatsoever, interest and fees would otherwise be payable
to Lender in excess of the maximum amount permissible under applicable law, the
interest and fees shall be reduced to the maximum amount permitted under
applicable law. If from any circumstance, Lender shall have received anything of
value deemed interest by applicable law in excess of the maximum lawful amount,
an amount equal to any excess of interest shall be applied to the reduction of
the principal amount of the Loans in such manner as may be determined by Lender,
and not to the payment of fees or interest, or if such excessive interest
exceeds the unpaid balance of principal amount of the Loans, such excess shall
be refunded to Boundless.

         2.5 Prior Loans. The Promissory Notes dated June 3, 2003, and July 1,
2003, as amended, evidencing all prior loans by Lender to Boundless (the "Prior
Loans"), shall be amended, restated and combined into one note to be dated as of
the Effective Date and shall be deemed to be a Loan under this Agreement (the
"New Note") and all principal and accrued but unpaid interest on the Prior
Loans, shall constitute the principal of such New Note. Upon execution and
delivery by Boundless of the New Note, the Prior Loans shall be marked
"Paid-in-Full."

                                  ARTICLE III
                              REPAYMENT OF THE NOTE

         3.1 Repayment of the Loans. Boundless covenants and agrees that upon
issuance of the New Note, it will repay to Lender, accrued and unpaid interest
on the Prior Loans. Boundless further covenants and agrees to repay to Lender
the unpaid principal balance of the Loans in full, together with all accrued and
unpaid interest, fees and other amounts due hereunder, on the Credit Termination
Date. Boundless may prepay the Loans, in whole or in

                                       4
<PAGE>

part, upon thirty (30) days prior written notice to Lender. All payments of the
Obligations hereunder, shall be secured by the Security Agreement.

         3.2 Home Office Payment. Boundless will pay all Obligations becoming
due to Lender in immediately available funds (by check or wire transfer to the
account(s) designated in writing by Lender) at the address in Section 8.9, or by
such other method or at such other address as Lender shall have from time to
time specified to Boundless in writing for such purpose, without the
presentation or surrender of the Note or the making of any notation thereon.

         3.3 Taxes.

               (a) All payments by Boundless to or for the account of Lender
hereunder or under the Note shall be made free and clear of and without
deduction for any and all Taxes. If Boundless shall be required by law to deduct
any Taxes from or in respect of any sum payable hereunder to Lender, (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 3.3) Lender receives an amount equal to the sum it would have
received had no such deductions been made, (ii) Boundless shall make such
deductions, (iii) Boundless shall pay the full amount deducted to the relevant
authority in accordance with applicable law and (iv) Boundless shall furnish to
Lender the original copy of a receipt evidencing payment thereof within 30 days
after such payment is made.

               (b) In addition, Boundless hereby agrees to pay any present or
future stamp or documentary taxes and any other excise or property taxes,
charges or similar levies which arise from any payment made hereunder or under
any Note or from the execution or delivery of, or otherwise with respect to,
this Agreement or any Note ("Other Taxes").

               (c) Boundless hereby agrees to indemnify Lender for the full
amount of Taxes or Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed on amounts payable under this Section 3.3) paid by Lender
and any liability (including penalties, interest and expenses) arising therefrom
or with respect thereto. Payments due under this indemnification shall be made
within 30 days of the date Lender makes demand therefore.

               (d) Lender, if entitled to an exemption from or reduction of
withholding tax with respect to payments under this Agreement or any Note
pursuant to the law of any relevant jurisdiction or any treaty, shall deliver to
Boundless, at the time or times prescribed by applicable law, such properly
completed and executed documentation prescribed by applicable law as will permit
such payments to be made without withholding or at a reduced rate.

         3.4 Certain Waivers. Boundless unconditionally waives (a) any rights to
presentment, demand, protest or (except as expressly required hereby) notice of
any kind, and (b) any rights of recession, setoff, deduction, counterclaim or
defense to payment under the Note or otherwise that Boundless may have or claim
against Lender.

                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES

         Boundless represents and warrants to Lender that:

         4.2 Authorization and Validity. Boundless has the power and authority
and legal right to execute and deliver the Loan Documents and to perform its

award binding on Boundless or any of its Subsidiaries or (b) Boundless' or any
Subsidiary's articles or certificate of incorporation, partnership agreement,
certificate of partnership, articles or certificate of organization, by-laws, or
operating or other management agreement, as the case may be, or (c) the
provisions of any indenture, instrument or agreement to which Boundless or any
of its Subsidiaries is a party or is subject, or by which it, or its Property,
is bound, or conflict with or constitute a default thereunder, or result in, or
require, the creation or imposition of any Lien in, of or on the Property of
Boundless or a Subsidiary pursuant to the terms of any such indenture,
instrument or agreement. No order, consent, adjudication, approval, license,
authorization, or validation of, or filing, recording or registration with, or
exemption by, or other action in respect of any governmental or public body or
authority, or any subdivision thereof, which has not been obtained by Boundless
or any of its Subsidiaries, is required to be obtained by Boundless or any of
its Subsidiaries in connection with the execution and delivery of the Loan

enforceability of any of the Loan Documents.

         6.10 The occurrence of any "default", as defined in any Loan Document

                                  ARTICLE VII
                                    DEFAULTS

         The occurrence of any one or more of the following events shall
constitute a Default:

         7.1 Acceleration. If any Default described in Section 6.5 or 6.6 occurs
with respect to Boundless, the obligations of Lender to make Loans hereunder
shall automatically terminate and the Obligations shall immediately become due
and payable without any election or action on the part of Lender. If any other
Default occurs, Lender may terminate or suspend the obligations of Lender to
make Loans hereunder, or declare the Obligations to be due and payable, or both,
whereupon the Obligations shall become immediately due and payable, without
presentment, demand, protest or notice of any kind, all of which Boundless
hereby expressly waives.

         7.2 Amendments. Subject to the provisions of this Article VII, Lender
and Boundless may enter into agreements supplemental hereto for the purpose of
adding or modifying any provisions to the Loan Documents or changing in any
manner the rights of Lender or Boundless

                                       8
<PAGE>

hereunder or waiving any Default hereunder; provided, however, that no such
supplemental agreement shall have any affect with respect to the terms and
conditions of any Note assigned to a third party by Lender, without such
assignee's written consent.

         7.3 Preservation of Rights. No delay or omission of Lender to exercise
any right under the Loan Documents shall impair such right or be construed to be
a waiver of any Default or an acquiescence therein, and the making of a Loan
notwithstanding the existence of a Default or the inability of Boundless to
satisfy the conditions precedent to such Loan shall not constitute any waiver or
acquiescence. Any single or partial exercise of any such right shall not
preclude other or further exercise thereof or the exercise of any other right,
and no waiver, amendment or other variation of the terms, conditions or
provisions of the Loan Documents whatsoever shall be valid unless in writing
signed by Lender required pursuant to Section 7.3, and then only to the extent
in such writing specifically set forth. All remedies contained in the Loan
Documents or by law afforded shall be cumulative and all shall be available to
Lender until the Obligations have been paid in full.

indemnification. The obligations of Boundless under this Section 7.6 shall
survive the termination of this Agreement.

         8.7 Severability of Provisions. Any provision in any Loan Document that
is held to be inoperative, unenforceable, or invalid in any jurisdiction shall,
as to that jurisdiction, be inoperative, unenforceable, or invalid without
affecting the remaining provisions in that jurisdiction or the operation,
enforceability, or validity of that provision in any other jurisdiction, and to
this end the provisions of all Loan Documents are declared to be severable.

         8.8 Nonliability of Lender. The relationship between Boundless on the
one hand and Lender on the other hand shall be solely that of borrower and
lender. Lender shall no have any fiduciary responsibilities to Boundless. Lender
does not undertake any responsibility to Boundless to review or inform Boundless
of any matter in connection with any phase of Boundless's business or
operations. Boundless agrees that Lender shall not have liability to Boundless
(whether sounding in tort, contract or otherwise) for losses suffered by
Boundless in connection with, arising out of, or in any way related to, the
transactions contemplated and the relationship established by the Loan
Documents, or any act, omission or event occurring in connection therewith,
unless it is determined in a final non-appealable judgment by a court of
competent jurisdiction that such losses resulted from the gross negligence or
willful misconduct of the party from which recovery is sought. Lender shall not
have any liability with respect to, and Boundless hereby waives, releases and
agrees not to sue for, any special, indirect or consequential damages suffered
by Boundless in connection with, arising out of, or in any way related to the
Loan Documents or the transactions contemplated thereby.

hereto may execute this Agreement by signing any such counterpart.
