                  (vii) the Company or any material Subsidiary of the Company

                           vi. the Company or any Subsidiary of the Company

                  term leasing or factoring arrangement of the Company in an

                  sell or dispose of all or in excess of 40% of its assets in
                  one or more transactions (whether or not such sale would
                  constitute a Change of Control Transaction) or shall redeem or
                  repurchase more than a de minimis number of its outstanding

                  other equity securities of departing officers and directors of
                  the Company; provided such repurchases shall not exceed
                  $100,000, in the aggregate, for all officers and directors
                  during the term of this Debenture).

                                        8


                  b) Remedies Upon Event of Default. If any Event of Default
         occurs, the full principal amount of this Debenture, together with
         interest and other amounts owing in respect thereof, to the date of
         acceleration shall become, at the Holder's election, immediately due
         and payable in cash. The aggregate amount payable upon an Event of
         Default shall be equal to the Mandatory Default Amount. Commencing 5
         days after the occurrence of any Event of Default that results in the
         eventual acceleration of this Debenture, the interest rate on this
         Debenture shall accrue at the rate of 18% per annum, or such lower
         maximum amount of interest permitted to be charged under applicable
         law. Upon the payment in full of the Mandatory Default Amount on this
         entire Debenture the Holder shall promptly surrender this Debenture.
         The Holder need not provide and the Company hereby waives any
         presentment, demand, protest or other notice of any kind, and the
         Holder may immediately and without expiration of any grace period
         enforce any and all of its rights and remedies hereunder and all other
         remedies available to it under applicable law. Such declaration may be
         rescinded and annulled by Holder at any time prior to payment hereunder
         and the Holder shall have all rights as a Debenture holder until such
         time, if any, as the full payment under this Section shall have been
         received by it. No such rescission or annulment shall affect any
         subsequent Event of Default or impair any right consequent thereon.

         Section 7. Miscellaneous.

                  a) Notices. Any and all notices or other communications or
         deliveries to be provided by the Holder hereunder, including, without
         limitation, any Notice of Conversion, shall be in writing and delivered
         personally, by facsimile, sent by a nationally recognized overnight
         courier service, addressed to the Company, at the address set forth
         above, facsimile number (360) 253-4830, ATTN: CHIEF EXECUTIVE OFFICER,
         or such other address or facsimile number as the Company may specify
         for such purposes by notice to the Holder delivered in accordance with
         this Section. Any and all notices or other communications or deliveries
         to be provided by the Company hereunder shall be in writing and
         delivered personally, by facsimile, sent by a nationally recognized
         overnight courier service addressed to each Holder at the facsimile
         telephone number or address of such Holder appearing on the books of
         the Company, or if no such facsimile telephone number or address
         appears, at the principal place of business of the Holder. Any notice
         or other communication or deliveries hereunder shall be deemed given
         and effective on the earliest of (i) the date of transmission, if such
         notice or communication is delivered via facsimile at the facsimile
         telephone number specified in this Section prior to 5:30 p.m. (New York
         City time), (ii) the date after the date of transmission, if such
         notice or communication is delivered via facsimile at the facsimile
         telephone number specified in this Section later than 5:30 p.m. (New
         York City time) on any date and earlier than 11:59 p.m. (New York City

         mailing, if sent by nationally recognized overnight courier service, or
         (iv) upon actual receipt by the party to whom such notice is required
         to be given.

                  b) Absolute Obligation. Except as expressly provided herein,
         no provision of this Debenture shall alter or impair the obligation of
         the Company, which is absolute and

                                        9


         unconditional, to pay the principal of, interest and liquidated damages
         (if any) on, this Debenture at the time, place, and rate, and in the
         coin or currency, herein prescribed. This Debenture is a direct debt
         obligation of the Company. This Debenture ranks pari passu with all
         other Debentures now or hereafter issued under the terms set forth
         herein.

                  c) Security Interest. This Debenture is a direct debt
         obligation of the Company and pursuant to the Security Agreement shall
         be secured by a perfected security interest in all of the assets of the
         Company for the benefit of the holders of the Series A Debentures and
         the Series B Debentures.

                  d) Lost or Mutilated Debenture. If this Debenture shall be
         mutilated, lost, stolen or destroyed, the Company shall execute and
         deliver, in exchange and substitution for and upon cancellation of a
         mutilated Debenture, or in lieu of or in substitution for a lost,
         stolen or destroyed Debenture, a new Debenture for the principal amount
         of this Debenture so mutilated, lost, stolen or destroyed but only upon
         receipt of evidence of such loss, theft or destruction of such
         Debenture, and of the ownership hereof, and indemnity, if requested,
         all reasonably satisfactory to the Company.

                  e) Governing Law. All questions concerning the construction,
         validity, enforcement and interpretation of this Debenture shall be
         governed by and construed and enforced in accordance with the internal
         laws of the State of New York, without regard to the principles of
         conflicts of law thereof. Each party agrees that all legal proceedings
         concerning the interpretations, enforcement and defense of the
         transactions contemplated by any of the Transaction Documents (whether
         brought against a party hereto or its respective affiliates, directors,
         officers, shareholders, employees or agents) shall be commenced in the
         state and federal courts sitting in the City of New York, Borough of
         Manhattan (the "New York Courts"). Each party hereto hereby irrevocably
         submits to the exclusive jurisdiction of the New York Courts for the
         adjudication of any dispute hereunder or in connection herewith or with
         any transaction contemplated hereby or discussed herein (including with
         respect to the enforcement of any of the Transaction Documents), and
         hereby irrevocably waives, and agrees not to assert in any suit, action
         or proceeding, any claim that it is not personally subject to the
         jurisdiction of any such court, or such New York Courts are improper or
         inconvenient venue for such proceeding. Each party hereby irrevocably
         waives personal service of process and consents to process being served
         in any such suit, action or proceeding by mailing a copy thereof via
         registered or certified mail or overnight delivery (with evidence of
         delivery) to such party at the address in effect for notices to it
         under this Debenture and agrees that such service shall constitute good
         and sufficient service of process and notice thereof. Nothing contained
         herein shall be deemed to limit in any way any right to serve process
         in any manner permitted by law. Each party hereto hereby irrevocably
         waives, to the fullest extent permitted by applicable law, any and all
         right to trial by jury in any legal proceeding arising out of or
         relating to this Debenture or the transactions contemplated hereby. If
         either party shall commence an action or proceeding to enforce any
         provisions of this Debenture, then the prevailing party in such action
         or proceeding shall be

                                       10


         reimbursed by the other party for its attorneys' fees and other costs
         and expenses incurred with the investigation, preparation and
         prosecution of such action or proceeding.

                  f) Waiver. Any waiver by the Company or the Holder of a breach
         of any provision of this Debenture shall not operate as or be construed
         to be a waiver of any other breach of such provision or of any breach
         of any other provision of this Debenture. The failure of the Company or
         the Holder to insist upon strict adherence to any term of this
         Debenture on one or more occasions shall not be considered a waiver or
         deprive that party of the right thereafter to insist upon strict
         adherence to that term or any other term of this Debenture. Any waiver
         must be in writing.

                  g) Severability. If any provision of this Debenture is
         invalid, illegal or unenforceable, the balance of this Debenture shall
         remain in effect, and if any provision is inapplicable to any person or
         circumstance, it shall nevertheless remain applicable to all other
         persons and circumstances. If it shall be found that any interest or
         other amount deemed interest due hereunder violates applicable laws
         governing usury, the applicable rate of interest due hereunder shall
         automatically be lowered to equal the maximum permitted rate of
         interest. The Company covenants (to the extent that it may lawfully do
         so) that it shall not at any time insist upon, plead, or in any manner
         whatsoever claim or take the benefit or advantage of, any stay,
         extension or usury law or other law which would prohibit or forgive the
         Company from paying all or any portion of the principal of or interest
         on this Debenture as contemplated herein, wherever enacted, now or at
         any time hereafter in force, or which may affect the covenants or the
         performance of this indenture, and the Company (to the extent it may
         lawfully do so) hereby expressly waives all benefits or advantage of
         any such law, and covenants that it will not, by resort to any such
         law, hinder, delay or impeded the execution of any power herein granted
         to the Holder, but will suffer and permit the execution of every such
         as though no such law has been enacted.

                  h) Next Business Day. Whenever any payment or other obligation
         hereunder shall be due on a day other than a Business Day, such payment
         shall be made on the next succeeding Business Day.

                  i) Headings. The headings contained herein are for convenience
         only, do not constitute a part of this Debenture and shall not be
         deemed to limit or affect any of the provisions hereof.

                  j) Assumption. Any successor to the Company or surviving
         entity in a Fundamental Transaction shall (i) assume in writing all of
         the obligations of the Company under this Debenture and the other
         Transaction Documents pursuant to written agreements in form and
         substance satisfactory to the Holder (such approval not to be
         unreasonably withheld or delayed) prior to such Fundamental Transaction
         and (ii) to issue to the Holder a new debenture of such successor
         entity evidenced by a written instrument substantially similar in form
         and substance to this Debenture, including, without limitation, having
         a principal amount and interest rate equal to the principal

                                       11


         amounts and the interest rates of the Debentures held by the Holder and
         having similar ranking to this Debenture, and satisfactory to the
         Holder (any such approval not to be unreasonably withheld or delayed).
         The provisions of this Section shall apply similarly and equally to
         successive Fundamental Transactions and shall be applied without regard
         to any limitations of this Debenture.
