PROMISE TO PAY. microHelix, Inc. ("Borrower") promises to pay to WEST COAST BANK
("Lender"), or order, in lawful money of the United States of America, the
principal amount of Seven Hundred Fifty Thousand & 00/100 Dollars ($750,000.00),
together with interest on the unpaid principal balance from December 21, 2001,
until paid in full.

PAYMENT. Subject to any payment changes resulting from changes in the index,
Borrower will pay this loan in 36 payments of $22,878.52 each payment.
Borrower's first payment is due January 30, 2002, and all subsequent payments
are due on the same day of each month after that. Borrower's final payment will
be due on December 30, 2004, and will be for all principal and all accrued
interest not yet paid. Payments include principal and interest. Unless otherwise
agreed or required by applicable law, payments will be applied first to accrued
unpaid interest, then to principal, and any remaining amount to any unpaid
collection costs and late charges. The annual interest rate for this Note is
computed on a 365/360 basis; that is, by applying the ratio of the annual
interest rate over a year of 360 days, multiplied by the outstanding principal
balance, multiplied by the actual number of days the principal balance is
outstanding. Borrower will pay Lender at Lender's address shown above or at such
other place as Lender may designate in writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an independent index which is the Prime rate as
published in the "Money Rates" section of the West Coast Edition of the Wall
Street Journal. (When a range of rates has been published, the higher of the
rates will be used) (the "Index"). The Index is not necessarily the lowest rate
charged by Lender on its loans. If the Index becomes unavailable during the term
of this loan, Lender may designate a substitute index after notice to Borrower.
Lender will tell Borrower the current Index rate upon Borrower's request. The
interest rate change will not occur more often than each day. Borrower
understands that Lender may make loans based on other rates as well. The Index
currently is 4.750% per annum. The Interest rate to be applied to the unpaid
principal balance of this Note will be at a rate of 1.250 percentage points over
the Index, resulting in an initial rate of 6.000% per annum. NOTICE: Under no
circumstances will the interest rate on this Note be more than the maximum rate
allowed by applicable law. Whenever increases occur in the interest rate,
Lender, at its option, may do one or more of the following: (A) increase
Borrower's payments to ensure Borrower's loan will pay off by its original final
maturity date, (B) increase Borrower's payments to cover accruing interest, (C)
increase the number of Borrower's payments, and (D) continue Borrower's payments
at the same amount and increase Borrower's final payment.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance charges
are earned fully as of the date of the loan and will not be subject to refund
upon early payment (whether voluntary or as a result of default), except as
otherwise required by law. Except for the foregoing, Borrower may pay without
penalty all or a portion of the amount owed earlier than it is due. Early
payments will not, unless agreed to by Lender in writing, relieve Borrower of
Borrower's obligation to continue to make payments under the payment schedule.
Rather, early payments will reduce the principal balance due and may result in
Borrower's making fewer payments. Borrower agrees not to send Lender payments
marked "paid in full", "without recourse", or similar language. If Borrower
sends such a payment, Lender may accept it without losing any of Lender's rights
under this Note, and Borrower will remain obligated to pay any further amount
owed to Lender. All written communications concerning disputed amounts,
including any check or other payment instrument that indicates that the payment
constitutes "payment in full" of the amount owed or that is tendered with other
conditions or limitations or as full satisfaction of a disputed amount must be
mailed or delivered to: WEST COAST BANK, WEST COAST CREDIT CENTER, P.O. BOX
8000, WILSONVILLE, OR 97070.

LATE CHARGE. If a payment Is 11 days or more late, Borrower will be charged
6.000% of the unpaid portion of the regularly scheduled payment or $25.00,
whichever is greater.

INTEREST AFTER DEFAULT. Upon default, including failure to pay upon final
maturity, Lender, of its option, may, if permitted under applicable law,
increase the variable interest rate on this Note to 7.250 percentage points over
the Index. The interest rate will not exceed the maximum rate permitted by
applicable law.

DEFAULT. Each of the following shall constitute an event of default ("Event of
Default") under this Note:

      Payment Default. Borrower fails to make any payment when due under this
      Note.

      Other Defaults. Borrower falls to comply with or to perform any other
      term, obligation, covenant or condition contained in this Note or in any

      obligation, covenant or condition contained in any other agreement between
      Lender and Borrower.

      includes a garnishment of any of Borrower's accounts, including deposit
      accounts, with Lender. However, this Event of Default shall not apply if
      there is a good faith dispute by Borrower as to the validity or
      reasonableness of the claim which is the basis of the creditor or
      forfeiture proceeding and if Borrower gives Lender written notice of the
      creditor or forfeiture proceeding and deposits with Lender monies or a
      surety bond for the creditor or forfeiture proceeding, in an amount
      determined by Lender, In its sole discretion, as being an adequate reserve

      or liability under, any guaranty of the indebtedness evidenced by this
      Note. In the event of a death, Lender, at its option, may, but shall not

      proceeding under any bankruptcy or insolvency laws by or against Borrower.

      Defective Collateralization. This Agreement or any of the Related
      Documents ceases to be in full force and effect (Including failure of any

      governmental agency against any collateral securing the Loan, This
      Includes a garnishment of any of Borrower's accounts, Including deposit
      accounts, with Lender. However, this Event of Default shall not apply if

      creditor or forfeiture proceeding and deposits with Lender monies or a

      respect to any Guarantor of any of the indebtedness or any Guarantor dies
      or becomes Incompetent, or revokes or disputes the validity of, or
      liability under, any Guaranty of the indebtedness. In the event of a
      death, Lender, at its option, may, but shall not be required to, permit
      the Guarantor's estate to assume unconditionally the obligations arising
      under the guaranty in a manner satisfactory to Lender, and, in doing so,
      cure any Event of Default.

      Adverse Change. A material adverse change occurs in Borrower's financial
      condition, or Lender believes the prospect of payment or performance of
      the Loan is impaired.

      demanding cure of such default. (1) cure the default within fifteen (15)
      days; or (2) it the cure requires more than fifteen (15) days, immediately
      initiate steps which Lender dooms in Lender's sole discretion to be

      reasonable and necessary steps sufficient to produce compliance as soon as
      reasonably practical,

kind to Borrower, except that in the case of an Event of Default of the type
described in the "Insolvency" subsection above, such acceleration shall be
automatic and not optional. In addition, Lender shall have all the rights and
remedies provided in the Related Documents or available at law, in equity, or
otherwise. Except as may be prohibited by applicable law, all of Lender's rights
and remedies shall be cumulative and may be exercised singularly or
concurrently. Election by Lender to pursue any remedy shall not exclude pursuit
of any other remedy, and an election to make expenditures or to take action to
perform an obligation of Borrower or of any Grantor shall not affect Lender's
right to declare a default and to exercise its rights and remedies.

      regardless of any investigation made by Lender, all such representations,
      warranties and covenants will survive the making of the Loan and delivery
      to Lender of the Related Documents, shall be continuing in nature, and
      shall remain in full force and effect until such time as Borrower's
      indebtedness shall be paid in full, or until this Agreement shall be
