INCIDENTAL
REGISTRATION RIGHTS





3.1           Right to
Include ("Piggy-Back") Registrable Securities.   Provided
that the Registrable Securities are not then registered, if at any time after
the Closing Date and prior to the date all Registrable Securities may be sold by
the Investor pursuant to Rule 144 under the 1933 Act, the Company proposes to
register any of its securities under the 1933 Act (other than by a registration
which would not permit registration of Registrable Securities for sale to the
public on Form S-8, or any successor form thereto, on Form S-4, or any successor
form thereto and other than pursuant toArticle 2) on an
underwritten basis (either best-efforts or firm-commitment), the Company will
each such time give prompt written notice to the Investor of its intention to
register its securities and the Investor's rights under this Section3.1.  Upon the written request of the Investor made
within fifteen (15) days after the receipt of any such notice from the Company
(which request will specify the Registrable Securities intended to be disposed
of by the Investor and the intended method of disposition thereof), the Company
will, subject to the terms of this Agreement, use its commercially reasonable
best efforts to include such Registrable Securities in the registration
statement which covers the securities which the Company proposes to
register.  The right provided the Investor pursuant to this Section3.1will be exercisable at the Investor's sole
discretion.

3.2           Withdrawal
or Delay of Registration.  If at any time after written notice
of its intention to register any securities and prior to the effective date of
the registration statement filed in connection with such registration the
Company determines for any reason either not to register or to delay
registration of such securities, the Company will give written notice of such
determination to the Investor.  In the case of a determination not to
register, the Company will be relieved of the obligation to register any
Registrable Securities in connection with such registration under Section3.1(but
not from its obligation to pay the Registration Expenses in connection
therewith), without prejudice, however, to the Investor's rights to registration
under Section2.1and
Section
2.2.  In the case of a determination to delay registering, the
Company will be permitted to delay registering any Registrable Securities, for
the same period as the delay in registering such other
securities.




3.3           Expenses.  The
Company will pay all Registration Expenses in connection with each registration
of Registrable Securities requested pursuant to Section3.1and
the Investor will pay its pro rata portion of the discounts or commissions
payable to any underwriter.




3.4           Priority
in Incidental Registrations.  If the managing underwriter of
the underwritten offering contemplated by Section3.1informs
the Company and the Investor in writing that the managing underwriter believes
that the number of securities requested to be included in such registration
exceeds the number which can be sold in such offering, then the Company will
include in such registration, up to the number of securities which the Company
is advised by the managing underwriter can be sold in such offering, (i) first,
securities proposed by the Company to be sold for its own account; and (ii)
second, a pro rata portion of the securities for which registration was
requested by the Investor and of all other registrable securities of the Company
of other selling security holders requested to be included in such
registration.

statement and the prospectus used in connection therewith as may be
necessary;

to the Investor such number of conformed copies of such registration statement
and of each such amendment and supplement thereto (in each case including all
exhibits), such number of copies of the prospectus contained in such
registration statement (including each preliminary prospectus and any summary
prospectus) and any other prospectus filed under Rule 424 under the 1933 Act, in

the Investor and underwriter may reasonably request in order to facilitate the
public sale or other disposition of the Registrable Securities owned by the
Investor;

(d)           use
its commercially reasonable best efforts to register or qualify all Registrable
Securities and other securities covered by such registration statement under
such other U.S. federal or state securities laws or U.S. state blue sky laws as
the Investor may reasonably request, to keep such registrations or
qualifications in effect for so long as such registration statement remains in
effect, and take any other action which may be reasonably necessary to enable
the Investor to consummate the disposition of the securities owned by the
Investor in such jurisdictions;





(e)           notify
the Investor promptly after the Company has knowledge that:





(i)           the

filed, and, with respect to the registration statement or any post-effective
amendment thereto, when the same has become effective;

SEC has issued any stop order suspending the effectiveness of the registration
statement or the initiation of any proceedings by any Person for that purpose;

qualification of any Registrable Securities for sale under the securities or
blue sky laws of any jurisdiction or the initiation or threat of any proceeding

event as a result of which, the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state any material facts required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstances
then existing, and, at the request of the Investor promptly prepare and furnish
to the Investor a reasonable number of copies of a supplement to or an amendment
of such prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such securities, such prospectus will not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing;





(g)           use
its commercially reasonable best efforts to obtain the withdrawal of any order
suspending the effectiveness of the registration statement at the earliest
possible moment;

requests in writing (at the expense of the Investor) in order to expedite or
facilitate the disposition of such Registrable Securities; and

its commercially reasonable best efforts to list all Registrable Securities

Securities until the Investor's receipt of the copies of the supplemented or
amended prospectus contemplated by Section4.1(f)and,
if so directed by the Company, will deliver to the Company (at the Company's
expense) all copies, other than permanent file copies, of the prospectus
relating to such Registrable Securities in the Investor's possession at the time
of receipt of such notice.

INDEMNIFICATION





6.1           Indemnification by the
Company.  In the event of any registration of any Registrable
Securities under the 1933 Act, the Company will, and hereby does agree to
indemnify and hold harmless the Investor, each individual or entity who
participates as an underwriter in the offering or sale of such securities and
each other person, if any, who controls the Investor or any such underwriter
within the meaning of the 1933 Act, against any losses, claims, damages, or
liabilities ("Losses") to which the
Investor or underwriter or controlling person may become subject under the 1933
Act or otherwise, insofar as such Losses (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the registration statement or prospectus, as amended or supplemented, or (ii)
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances in which they are made, not misleading.  The Company
will reimburse the Investor and each such underwriter and controlling person for
any legal or any other expenses reasonably incurred by them in connection with
investigating or defending against any such Loss, provided that the Company will
not be liable in any such case to the extent that any such Loss (or action or
proceeding in respect thereof) or expense arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement, prospectus, amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by the Investor or underwriter.  Further, the Company will not
be liable to any underwriter in the offering or sale of Registrable Securities
or to any other person, if any, who controls such underwriter within the meaning
of the 1933 Act, to the extent that any such Loss (or action or proceeding in
respect thereof) or expense arises out of such underwriter or controlling
person's failure to send or give a copy of the final prospectus, as the same may
be then supplemented or amended, within the time required by the 1933 Act to the
person or entity asserting the existence of an untrue statement or alleged
untrue statement or omission or alleged omission at or prior to the written
confirmation of the sale of Registrable Securities to such person or entity, if
such statement or omission was corrected in such final prospectus or an
amendment or supplement thereto.  Such indemnity will remain in full
force and effect regardless of any investigation made by or on behalf of the
Investor or any such underwriter or controlling person and will survive the
transfer of such securities by the Investor .

6.2           Indemnification
by the Investor.  The Company may require, as a condition to
including any Registrable Securities in any registration statement filed
pursuant to this Agreement, that the Investor provide an undertaking
satisfactory to the Company that the Investor will indemnify and hold harmless
(in the same manner and to the same extent as set forth in Section6.1) the
Company, each director of the Company, each officer of the Company and each
other person, if any, who controls the Company within the meaning of the 1933
Act, with respect to any statement or alleged statement in or omission or
alleged omission from such registration statement or prospectus, or any
amendment or supplement thereto, if such statement or omission or alleged
statement or omission was made in reliance upon and in conformity with written
information furnished to the Company through an instrument duly executed by the
Investor specifically stating that it is for use in the preparation of such
registration statement, prospectus, amendment or supplement.  Any such
indemnity will remain in full force and effect, regardless of any investigation
made by or on behalf of the Company or any such director, officer or controlling
person and will survive the transfer of such securities by the
Investor.  The liability of the Investor under this Section6.1will
be limited to the net proceeds from the offering received by the
Investor.





6.3           Notices
of Claims, Etc.  Promptly after receipt by an indemnified party
of notice of the commencement of any action or proceeding involving a claim
referred to in Section6.1or
Section6.2, such
indemnified party will give written notice to the indemnifying party of the
commencement of such action.  The failure of any indemnified party to
give notice as provided herein will not relieve the indemnifying party of its
obligations under Section6.1or
Section6.2, except to
the extent that the indemnifying party is actually prejudiced by such failure to
give notice.  In case any such action is brought against an
indemnified party, unless in such indemnified party's reasonable judgment a
conflict of interest between such indemnified and indemnifying parties may exist
in respect of such claim, the indemnifying party will be entitled to participate
in and to assume the defense thereof, jointly with any other indemnifying party
similarly notified, to the extent that the indemnifying party may wish, with
counsel reasonably satisfactory to such indemnified party.  After
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party will not be liable to such
indemnified party for any legal or other expenses subsequently incurred by the
indemnified party in connection with the defense thereof.  No
indemnifying party will, without the consent of the indemnified party, consent
to entry of any judgment or enter into any settlement of any such action which
does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability, or a
covenant not to sue, in respect to such claim or litigation.  No
indemnified party will consent to entry of any judgment or enter into any
settlement of any such action the defense of which has been assumed by an
indemnifying party without the consent of such indemnifying
party.

6.4           Other
Indemnification.  Indemnification similar to that specified in
Section6.1and
Section6.2(with
appropriate modifications) will be given by the Company and the Investor (but
only if and to the extent required pursuant to the terms herein) with respect to
any required registration or other qualification of securities under any Federal
or state law or regulation of any governmental authority other than the 1933
Act.




6.5           Indemnification
Payments.  The indemnification required by Sections6.1and6.2will
be made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or expense, loss,
damage or liability is incurred.




6.6           Contribution.  If
recovery is not available under the foregoing indemnification provisions, for
any reason other than as specified therein, the parties entitled to
indemnification by the terms thereof will be entitled to contribution to
liabilities and expenses as more fully set forth in an underwriting agreement to
be executed in connection with such registration.  In determining the
amount of such contribution to which the respective parties are entitled, there
will be considered the parties' relative knowledge and access to information
concerning the matter with respect to which the claim was asserted, the
opportunity to correct and prevent any statement or omission, and any other
equitable considerations appropriate under the circumstances.  No
person or entity guilty of fraudulent misrepresentation will be entitled to
contribution from any person or entity that was not guilty of such fraudulent
misrepresentation.

8.3           Assignment.  This
Agreement will be binding upon and inure to the benefit of the parties hereto,
their heirs, personal representatives, successors, and assigns.  Each
holder of Registrable Securities agrees, by accepting any portion of the
Registrable Securities after the date hereof, to the provisions of this
Agreement.





8.4           Headings.  The
descriptive headings of the several sections of this Agreement are inserted for
reference only and will not be used to construe or interpret this
Agreement.





8.5           Governing Law;
Jurisdiction.  This Agreement will be deemed a contract made
under the laws of the State of Oregon and, together with the rights and
obligations of the parties hereunder, will be construed under and governed by
the laws of such State, without giving effect to principles of conflicts of
law.  The parties hereto irrevocably submit to the jurisdiction of any
state or federal court sitting in Multnomah County, Oregon, in any action or
proceeding brought to enforce or otherwise arising out of or relating to this
Agreement, and hereby waive any objection to venue in any such court and any
claim that such forum is an inconvenient forum.

8.6           Waiver of Jury Trial;
Attorney Fees.  Each party irrevocably waives any right it may
have, and agrees not to request, a jury trial for the adjudication of any
dispute hereunder or in connection herewith or arising out of this Agreement or
any transaction contemplated hereby.  In the event suit or action is
brought by any party under this Agreement to enforce any of its terms, or in any
appeal therefrom, it is agreed that the prevailing party will be entitled to
reasonable attorneys fees to be fixed by the arbitrator, trial court, and/or
appellate court.





8.7           Entire

parties with respect to the subject matter of this Agreement and supersedes all
prior agreements and understandings, whether written or oral, between the
parties with respect to such subject matter.





8.8           Severability.  Each
provision of this Agreement will be treated as a separate and independent
clause, and the unenforceability of any one clause will in no way impair the
enforceability of any of the other clauses.  Moreover, if one or more
of the provisions contained in this Agreement will, for any reason, be held to
be excessively broad as to scope, activity, or subject so as to be unenforceable
at law, such provision or provisions will be construed by the appropriate
judicial body by limiting and reducing it or them, so as to be enforceable to
the maximum extent compatible with the applicable law as it will then
appear.





8.9           Failure or Indulgence Not
Waiver; Remedies Cumulative.  No failure or delay on the part
of any party hereto in the exercise of any right hereunder will impair such
right or be construed to be a waiver of, or acquiescence in, any breach of any
representation, warranty, covenant or agreement herein, nor will any single or
partial exercise of any such right preclude other or further exercise thereof or
of any other right.  All rights and remedies existing under this
Agreement are cumulative to, and not exclusive of, any rights or remedies
otherwise available.





8.10           Time is of the
Essence.  Time is of the essence for each and every provision
of this Agreement.





8.11           Injunctive
Relief.  The parties agree that a breach or violation of this
Agreement will result in immediate and irreparable harm to the non-breaching
parties in an amount that will be impossible to ascertain at the time of the
breach or violation, and that the award of monetary damages will not be adequate
relief to the non-breaching parties.  The non-breaching party will be
entitled to seek equitable or injunctive relief, in addition to other remedies
to which it may be entitled at law or equity.  In any action for
equitable relief, the parties agree to waive any requirement for the posting of
a bond or security.





8.12           Counterparts.  This Agreement may be
executed in one or more counterparts, each of which when executed will be deemed
to be an original, but all of which taken together will constitute one and the
same agreement.  A facsimile transmission of this signed Agreement
will be legal and binding on all parties hereto.




IN WITNESS WHEREOF, the Company and the
Investor have executed this Agreement as of the day and year first above
