                        BIOJECT MEDICAL TECHNOLOGIES INC.


     Pursuant to ORS 60.431,  the undersigned  corporation  adopts the following
Articles of Amendment to its Articles of Incorporation:

     FIRST:  The name of the  corporation is Bioject Medical  Technologies  Inc.
(the "Corporation").

     SECOND: The Articles of Incorporation are hereby amended as follows:

     Article X is hereby deleted in its entirety and replaced with a new Article
X to read as follows:


                                    ARTICLE X

                                    Directors

Section 1. Number of Directors.

     The Board of  Directors  shall  consist  of not less than six nor more than
eleven,  the exact  number to be set herein.  Until  increased  or  decreased as
provided  herein,  the Board of Directors  shall consist of eight  members.  The
Board of Directors is  authorized  to increase or decrease the size of the Board
of Directors  (within the range specified  above) at any time by the affirmative
vote of  two-thirds  of the  directors  then in office.  Without  the  unanimous
consent of the directors then in office,  no more than two additional  directors
shall be added to the Board of  Directors in any  12-month  period.  Without the
unanimous  approval of the directors then in office, no person who is affiliated
as an owner, director,  officer, employee or consultant of a company or business
deemed by the Board of Directors to be competitive  with that of the Corporation
shall be eligible to serve on the Board of Directors of the Corporation.

Section 2. Classified Board.

     The Board shall be divided into three classes: Class I Directors,  Class II
Directors, and Class III Directors. Each such class of directors shall be nearly
equal in number of directors as possible.  Each director  shall serve for a term
ending at the third annual shareholders' meeting following the annual meeting at
which such director was elected;  provided,  however,  that the directors  first
elected as Class I Directors shall serve for a term ending at the annual meeting
to be held in the year following the first election of directors by classes, the
directors  first elected as Class II Directors  shall serve for a term ending at
the annual meeting to be held in the second year following the first election of
directors  by classes and the  directors  first  elected as Class III  directors
shall serve for a term ending at the annual meeting to be held in the third year
following  the first  election  of  directors  by classes.  Notwithstanding  the
foregoing,  each director shall serve until his or her successor shall have been
elected and qualified or until his or her earlier death, resignation or removal.

     At each annual election,  the directors chosen to succeed those whose terms
then expire shall be identified as being of the same class as the directors they
succeed,  unless, by reason of any intervening  changes in the authorized number
of directors,  the Board shall  designate one or more  directorships  whose term
then expire as  directorships  of another  class in order more nearly to achieve
equality in the number of directors  among the  classes.  When the Board fills a
vacancy  resulting  from the death,  resignation  or removal of a director,  the
director  chosen to fill that vacancy shall be of the same class as the director
he or she succeeds,  unless, by reason of any previous changes in the authorized
number of  directors,  the Board shall  designate the vacant  directorship  as a
directorship  of another  class in order more nearly to achieve  equality in the
number of directors among the classes.  The terms of any director elected by the
Board to fill a vacancy  will expire at the next  shareholders  meeting at which
directors are elected, despite the class such director has been elected to fill.





     Notwithstanding the rule that the three classes shall be as nearly equal in
number of  directors as possible,  upon any change in the  authorized  number of
directors,  each  director then  continuing  to serve as such will  nevertheless
continue  as a director  of the class of which he or she is a member,  until the
expiration of his or her current term or his or her earlier  death,  resignation
or removal.

     Newly created  directorships  resulting  from any increase in the number of
directors  and any  vacancies  on the Board of Directors  resulting  from death,
resignation, removal or other cause shall be filled by the affirmative vote of a
majority  of the  remaining  directors  then in office,  even though less than a
quorum  of the Board of  Directors.  No  decrease  in the  number  of  directors
constituting  the Board of  Directors  shall  shorten the term of any  incumbent
director.

Section 3. Initial Directors as Classified.

     The directors of the Corporation  first elected to classes are eight (8) in
number and their names and class are:

Richard J. Plestina     2
David H. de Weese       1
Michael T. Sember       3
- -------------            

Section 4. Removal of Directors

     Directors  may be removed only for cause.  For purposes of this  Amendment,
"cause"  shall mean that the  director  has:  (i)  committed  an act of fraud or
embezzlement  against the  Corporation;  (ii) been  convicted  of, or plead nolo
contendere to a crime  involving  moral  turpitude;  (iii) failed to perform the
director's  duties as a director  and such failure  constitutes  a breach of the
director's duty of loyalty to the  Corporation or provides an improper  personal
benefit to the director.





     A new Article XII is hereby added and reads as follows:

                                   ARTICLE XII

                     SHAREHOLDER APPROVAL OF CERTAIN EVENTS

     Notwithstanding any provision of Articles of Incorporation,  as amended, or
Bylaws of the Corporation,  as amended,  and  notwithstanding the fact that some
lesser  percentage  may be allowed by law,  any  amendment,  change or repeal of
Articles X or XII, or any other amendment of the Articles of  Incorporation,  as
amended, which would have the effect of modifying or permitting circumvention of
the  provisions of Articles X or XII,  shall  require the following  shareholder
votes: (i) the affirmative votes of 75 percent of all outstanding  shares of the
Corporation  entitled to vote on the matter,  voting together as a single class;
and (ii) if any shares of the  Corporation are entitled to vote on the matter as
a separate  group,  the  affirmative  vote of 75 percent of such shares,  voting
separately.
