     FOR VALUE RECEIVED, Portland Brewing Company, an Oregon corporation,

senior security interest in the same assets held by Bank of America.  In the
event of a default under the loan agreement with this bank, payment of the

authorized by the Company in an aggregate principal amount not to exceed
$400,000.

     REDEMPTION.  This note may be redeemed by the Company at any time, in 
whole or in part, without premium or penalty.  Partial prepayments shall be 
applied against the installments which mature last. This note shall be

merges with another company, or sells its capital stock in an underwritten 
public offering.

assigned without the prior written consent of the Company.

     DEFAULT.  The Company agrees that the unpaid principal balance of this 
note and accrued interest shall become immediately due and payable at the 
demand of the Holder in the event of:

     (a)  A default in any payment of principal or interest due should such
default continue for a period of thirty (30) days;

     (b)  A payment default or other material default which remains uncured for
thirty (30) days after the Company has notice thereof under the loan agreement
with Bank of America, or successor bank; or

     (c)   An election by any other holder of an Amortizing Subordinated Note
of the Company to accelerate the maturity of any such note because of a payment
default;  (d)  The appointment of a receiver for the Company, an assignment for
the benefit of creditors by the Company, or the filing of a petition for relief
under any bankruptcy or insolvency law by or against the Company.

     In such an event if the Company does not pay the remaining principal
balance and accrued interest in full within thirty days following demand
therefor by the Holder, this note shall then (from the date of the

have been cured and the installment payments have been reinstated to the 
satisfaction of the Holder.

this note, the Company agrees to pay such additional sum as reasonable 
attorney's fees as may be determined by the court upon any trial or appeal 
therefrom.

Subordinated Note, Due June 1, 2002 to be executed by its duly authorized
officer this 31st day of December, 1997.
