including July 1, 2006, not to exceed at any time the aggregate principal amount
of Four Million  Dollars  ($4,000,000.00)  ("Line of  Credit"),  the proceeds of
which  shall  be  used  to  finance  Borrower's  working  capital  requirements.
Borrower's  obligation  to repay  advances  under  the Line of  Credit  shall be
evidenced by a promissory note dated as of July 1, 2005 ("Line of Credit Note"),

affiliate to issue standby  letters of credit for the account of Borrower (each,
a "Letter  of Credit"  and  collectively,  "Letters  of  Credit").  The form and

borrowings thereunder.  Each Letter of Credit shall be subject to the additional
terms and conditions of the Letter of Credit  agreements,  applications  and any
related documents required by Bank in connection with the issuance thereof. Each
drawing paid under a Letter of Credit shall be deemed an advance  under the Line
of  Credit  and shall be repaid by  Borrower  in  accordance  with the terms and
conditions of this Agreement applicable to such advances; provided however, that
if advances under the Line of Credit are not available,  for any reason,  at the
time any drawing is paid,  then Borrower shall  immediately pay to Bank the full
amount drawn,  together with interest thereon from the date such drawing is paid
to the date such  amount is fully  repaid by  Borrower,  at the rate of interest
applicable to advances under the Line of Credit.  In such event Borrower  agrees
that Bank, in its sole discretion,  may debit any account maintained by Borrower
with Bank for the amount of any such drawing.

     (c) Borrowing and Repayment. Borrower may from time to time during the term
of the  Line of  Credit  borrow,  partially  or  wholly  repay  its  outstanding
borrowings,  and  reborrow,  subject

the Line of Credit  shall not at any time  exceed the maximum  principal  amount
available thereunder, as set forth above.

     SECTION 1.2. INTEREST/FEES.

     (a) Interest. The outstanding principal balance of the Line of Credit shall

is  fully  repaid  by  Borrower,  at the  rate of  interest  set  forth  in each
promissory  note  or  other  instrument  or  document   executed  in  connection
therewith. (b) Computation and Payment.  Interest shall be computed on the basis

upon the payment or  negotiation  of each drawing under any Letter of Credit and
fees upon the  occurrence  of any other  activity  with respect to any Letter of
Credit (including without limitation, the transfer, amendment or cancellation of
any Letter of Credit)  determined  in accordance  with Bank's  standard fees and
charges then in effect for such activity.

     SECTION 1.3.  COLLECTION OF PAYMENTS.  Borrower  authorizes Bank to collect

otherwise  affect any other or further  exercise  thereof or the exercise of any
other right,  power or remedy.  Any waiver,  permit,  consent or approval of any
kind by Bank of any breach of or default under any of the Loan Documents must be
in writing and shall be effective only to the extent set forth in such writing.

     SECTION 7.7.  TIME.  Time is of the essence of each and every  provision of
this Agreement and each other of the Loan Documents.

     SECTION 7.8. SEVERABILITY OF PROVISIONS. If any provision of this Agreement

invalidating the remainder of such provision or any remaining provisions of this
Agreement.

     SECTION 7.9. COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which when executed and delivered shall be deemed to be an
original, and all of which when taken together shall constitute one and the same
Agreement.

     SECTION  7.10.GOVERNING  LAW.  This  Agreement  shall  be  governed  by and
construed in accordance with the laws of the State of Oregon.

     SECTION 7.11.ARBITRATION.

     (a)  Arbitration.  The parties hereto agree,  upon demand by any party,  to
submit to binding arbitration all claims,  disputes and controversies between or
among them (and their respective employees, officers, directors,  attorneys, and
other agents), whether in tort, contract or otherwise arising out of or relating
to in any way (i) the loan and related Loan  Documents  which are the subject of
this   Agreement   and   its    negotiation,    execution,    collateralization,
administration,  repayment, modification,  extension,  substitution,  formation,
inducement, enforcement, default or termination; or (ii) requests for additional
credit.

     (b)  Governing  Rules.  Any  arbitration  proceeding  will (i) proceed in a
location in Oregon  selected by the American  Arbitration  Association  ("AAA");
(ii) be governed by the Federal  Arbitration  Act (Title 9 of the United  States
Code),  notwithstanding  any  conflicting  choice of law provision in any of the
documents between the parties;  and (iii) be conducted by the AAA, or such other
administrator  as the parties shall mutually agree upon, in accordance  with the
AAA's commercial dispute resolution procedures, unless the claim or counterclaim
is at least  $1,000,000.00  exclusive of claimed interest,  arbitration fees and
costs in which case the  arbitration  shall be conducted in accordance  with the
AAA's optional procedures for large, complex commercial disputes (the commercial
dispute  resolution  procedures or the optional  procedures  for large,  complex
commercial disputes to be referred to, as applicable,  as the "Rules"). If there
is any  inconsistency  between  the terms  hereof and the  Rules,  the terms and

                                       10


procedures  set forth  herein shall  control.  Any party who fails or refuses to
submit to arbitration following a demand by any other party shall bear all costs
and  expenses  incurred by such other  party in  compelling  arbitration  of any
dispute.  Nothing  contained  herein shall be deemed to be a waiver by any party
that is a bank of the  protections  afforded to it under 12 U.S.C.  ss.91 or any
similar applicable state law.

     (c) No Waiver of  Provisional  Remedies,  Self-Help  and  Foreclosure.  The
arbitration  requirement  does not limit the right of any party to (i) foreclose
against real or personal property  collateral;  (ii) exercise self-help remedies
relating to collateral or proceeds of collateral such as setoff or repossession;
or (iii) obtain provisional or ancillary  remedies such as replevin,  injunctive
relief,  attachment or the appointment of a receiver, before during or after the
pendency of any  arbitration  proceeding.  This  exclusion does not constitute a
waiver  of the  right or  obligation  of any  party to  submit  any  dispute  to
arbitration or reference hereunder, including those arising from the exercise of
the actions detailed in sections (i), (ii) and (iii) of this paragraph.

     (d) Arbitrator  Qualifications  and Powers.  Any arbitration  proceeding in
which the amount in  controversy is  $5,000,000.00  or less will be decided by a
single arbitrator  selected  according to the Rules, and who shall not render an
award of  greater  than  $5,000,000.00.  Any  dispute  in which  the  amount  in
controversy  exceeds  $5,000,000.00 shall be decided by majority vote of a panel
of three arbitrators; provided however, that all three arbitrators must actively
participate in all hearings and deliberations.  The arbitrator will be a neutral
attorney licensed in the State of Oregon or a neutral retired judge of the state
or  federal  judiciary  of  Oregon,  in either  case with a minimum of ten years
experience  in the  substantive  law  applicable  to the  subject  matter of the
dispute to be arbitrated.  The arbitrator will determine whether or not an issue
is  arbitratable  and  will  give  effect  to  the  statutes  of  limitation  in
determining any claim. In any arbitration  proceeding the arbitrator will decide
(by  documents  only or  with a  hearing  at the  arbitrator's  discretion)  any
pre-hearing motions which are similar to motions to dismiss for failure to state
a claim or motions for summary  adjudication.  The arbitrator  shall resolve all
disputes  in  accordance  with the  substantive  law of Oregon and may grant any
remedy or relief  that a court of such  state  could  order or grant  within the
scope hereof and such  ancillary  relief as is necessary to make  effective  any
award.  The arbitrator  shall also have the power to award recovery of all costs
and fees, to impose  sanctions  and to take such other action as the  arbitrator
deems  necessary to the same extent a judge could  pursuant to the Federal Rules
of Civil Procedure, the Oregon Rules of Civil Procedure or other applicable law.
Judgment upon the award  rendered by the  arbitrator may be entered in any court
having  jurisdiction.  The institution and maintenance of an action for judicial
relief or pursuit of a provisional  or ancillary  remedy shall not  constitute a
waiver  of the right of any  party,  including  the  plaintiff,  to  submit  the
controversy  or claim to arbitration if any other party contests such action for
judicial relief.

     (e) Discovery. In any arbitration proceeding discovery will be permitted in
accordance with the Rules.  All discovery shall be expressly  limited to matters
directly relevant to the dispute being arbitrated and must be completed no later
than 20 days  before the  hearing  date and within 180 days of the filing of the
dispute with the AAA. Any requests for an extension of the discovery periods, or
any discovery disputes, will be subject to final determination by the arbitrator
upon a showing  that the  request for  discovery  is  essential  for the party's
presentation  and  that  no  alternative  means  for  obtaining  information  is
available.

     (f) Class  Proceedings  and  Consolidations.  The resolution of any dispute
arising  pursuant  to the  terms  of this  Agreement  shall be  determined  by a
separate arbitration

                                       11


proceeding  and such dispute shall not be  consolidated  with other  disputes or
included in any class proceeding.

     (g) Payment Of Arbitration  Costs And Fees. The arbitrator  shall award all
costs and expenses of the arbitration proceeding.

     (h)  Miscellaneous.  To  the  maximum  extent  practicable,  the  AAA,  the
arbitrators  and the parties  shall take all action  required  to  conclude  any
arbitration  proceeding  within 180 days of the filing of the  dispute  with the
AAA. No arbitrator or other party to an arbitration  proceeding may disclose the
existence,  content or results thereof, except for disclosures of information by
a party required in the ordinary  course of its business or by applicable law or
regulation. If more than one agreement for arbitration by or between the parties
potentially  applies to a  dispute,  the  arbitration  provision  most  directly
related  to the Loan  Documents  or the  subject  matter  of the  dispute  shall
control.  This  arbitration  provision shall survive  termination,  amendment or
expiration of any of the Loan Documents or any relationship between the parties.

     UNDER OREGON LAW, MOST  AGREEMENTS,  PROMISES AND COMMITMENTS  MADE BY BANK
CONCERNING LOANS AND OTHER CREDIT EXTENSIONS WHICH ARE NOT FOR PERSONAL,  FAMILY
OR HOUSEHOLD  PURPOSES OR SECURED SOLELY BY THE BORROWER'S  RESIDENCE MUST BE IN
WRITING, EXPRESS CONSIDERATION AND BE SIGNED BY BANK TO BE ENFORCEABLE.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed
as of the day and year first written above.
