REGISTRATION RIGHTS AGREEMENT

      THIS REGISTRATION RIGHTS AGREEMENT (the "AGREEMENT") is made and entered
into as April 8, 2005 by and between microHelix, Inc., a corporation organized
and existing under the laws of the State of Oregon (the "Company"), and each
Investor who is a party to the Agreement (each of whom individually is referred
to herein as an "INVESTOR" and collectively are referred to as the "INVESTORS").

                              PRELIMINARY STATEMENT

      WHEREAS, pursuant to the Series B Preferred Stock Purchase Agreement dated
as of April 8, 2005, by and among the Company and the Investors (the "PREFERRED
STOCK PURCHASE AGREEMENT"), each Investor will purchase Series B Preferred
Stock, no par value (the "SERIES B PREFERRED"), which, upon conversion entitles
the Investor to receive Shares (as defined in Section 1.3);

      WHEREAS, the ability of the Investors to sell their Shares is subject to
certain restrictions under the Securities Act of 1933, as amended (the "1933
ACT"); and

      WHEREAS, the Company has agreed to provide the Investors with a mechanism
that will permit the Investors to sell their Shares in the future;

      NOW, THEREFORE, in consideration of the mutual covenants and agreements,
and subject to the terms and conditions contained herein, the parties hereby
agree as follows:

                                   ARTICLE 1
                                   DEFINITIONS

securities convertible into Registrable Securities.

      1.3 "SHARES" means, collectively, the shares of Common Stock of the
Company issued or issuable upon conversion of the Series B Preferred.

      1.4 "REGISTRABLE SECURITIES" means and includes the Shares. Shares will
cease to be Registrable Securities when (a) they have been effectively
registered under the 1933 Act and disposed of in accordance with the
registration statement covering them, (b) they are or may be freely traded
within any three-month period without registration pursuant to Rule 144 under
the 1933 Act (or any similar provisions that are then in effect), or (c) they

restrictive legend have been issued by Company, and Company does not have "stop
transfer" instructions against them.

<PAGE>

      1.5 "REGISTRATION EXPENSES" means all expenses incurred by the Company in
complying with its obligations under this Agreement, excluding all underwriting
discounts and selling commissions applicable to Registrable Shares.

                                   ARTICLE 2
                           DEMAND REGISTRATION RIGHTS

      2.1 DEMAND REGISTRATION. At any time after the Closing Date and prior to
the date all Registrable Securities may be sold by all of the Holders pursuant
to Rule 144 under the 1933 Act, the Holders of at least twenty five percent
(25%) of the Registrable Securities initially issuable on the Closing Date may
request, once and only once, in writing the registration under the 1933 Act of
all or part of the Registrable Securities then outstanding. Within twenty (20)
days after receipt of any such request, the Company will give written notice of
such request to all other Holders. The Company will include in such registration
all Registrable Securities held by all the Holders who wish to participate in
such demand registration and provide the Company with written requests for
inclusion therein within fifteen (15) days after receipt of the Company's
notice.

      2.2 REGISTRATION STATEMENT FORM. Registrations under Section 2.1 will be
on the appropriate registration form of the Securities and Exchange Commission
("SEC") as will permit the disposition of such Registrable Securities in
accordance with the intended method or methods of disposition specified in the
registration statement.

      2.3 EXPENSES. The Company will pay all Registration Expenses in connection
with any registration required under Section 2.1, and each Holder participating
in such registration will pay its pro rata portion of the discounts or
commissions payable to any underwriter.

                                   ARTICLE 3
                         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 all
of the Holders 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 to Section 2) on an underwritten
basis (either best-efforts or firm-commitment), the Company will each such time
give prompt written notice to all Holders of Registrable Securities of its
intention to register its securities and of such Holders' rights under this
Section 3.1. Upon the written request of any such Holders 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 such
Holders 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 Holders of the Registrable Securities pursuant to this Section 3.1
will be exercisable at their sole discretion.

                                       2

      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 each Holder of Registrable Securities. 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
Section 3.1 (but not from its obligation to pay the Registration Expenses in
connection therewith), without prejudice, however, to the rights of any Holders
of Registrable Securities entitled to request that such registration be effected
as a registration under Section 2.1. 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. No registration effected under Section 3.1 will relieve the Company
of its obligation to effect any registration demanded under Section 2.1.

      3.3 EXPENSES. The Company will pay all Registration Expenses in connection
with each registration of Registrable Securities requested pursuant to this
Section 3.1 and each Holder participating in such registration 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 Section 3.1 informs the Company and
Holders of the Registrable Securities in writing that it 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; (ii) second, a pro rata
portion of the Registrable Securities for which registration was requested by
each participating Holder, and (iii) third, a pro rata portion of securities of
other selling security holders requested to be included in such registration.

                                   ARTICLE 4
                             REGISTRATION PROCEDURES

      4.1 REGISTRATION PROCEDURES. If and whenever the Company is required to
effect the registration of any Registrable Securities under the 1933 Act as
provided in Section 2.1 and, as applicable, Section 3.1, the Company will, as
expeditiously as possible:

            (a) prepare and file with the SEC the registration statement, or
amendments thereto, to effect such registration (including such audited
financial statements as may be required by the 1933 Act or the rules and
regulations promulgated thereunder) and thereafter use its commercially
reasonable best efforts to cause such registration statement to be declared
effective by the SEC as soon as practicable;

            (b) prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection therewith as
may be necessary;

                                       3
<PAGE>

            (c) furnish to each Holder of Registrable Securities covered by such
registration statement 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 conformity with the requirements of the 1933 Act, and such other
documents, as such Holder and underwriter may reasonably request in order to
facilitate the public sale or other disposition of the Registrable Securities
owned by such Holder;

            (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 any U.S. Holder of Registrable Securities 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 such Holder to consummate the
disposition of the securities owned by such Holder in such jurisdictions;

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

                  (i) the registration statement, the prospectus or any
            prospectus supplement related thereto or post-effective amendment to
            the registration statement has been filed, and, with respect to the
            registration statement or any post-effective amendment thereto, when
            the same has become effective;

                  (ii) the 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; or

                  (iii) the Company has received any notification with respect
            to the suspension of the 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 for such purpose;

            (f) notify each Holder of Registrable Securities covered by such
registration statement, at any time when a prospectus relating thereto is
required to be delivered under the 1933 Act, upon discovery that, or upon the
happening of any 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 any such Holder promptly
prepare and furnish to such Holder 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;

                                       4
<PAGE>

            (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;

            (h) enter into such agreements and take such other actions as a
Holder reasonably requests in writing (at the expense of the requesting or
benefiting Holders) in order to expedite or facilitate the disposition of such
Registrable Securities; and

            (i) use its commercially reasonable best efforts to list all
Registrable Securities covered by such registration statement on any securities
exchange on which any of the Registrable Securities are then listed.

The Company may require each Holder of Registrable Securities as to which any
registration is being effected to furnish the Company with information regarding
such Holder and the distribution of such securities.

      4.2 AMENDED PROSPECTUS. Each Holder of Registrable Securities agrees that,
upon receipt of any notice from the Company of the occurrence of any event of
the kind described in Section 4.1(f), such Holder will forthwith discontinue
such Holder's disposition of Registrable Securities pursuant to the registration
statement relating to such Registrable Securities until such Holder's receipt of
the copies of the supplemented or amended prospectus contemplated by Section
4.1(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 Holder's possession at the
time of receipt of such notice.

                                   ARTICLE 5
                             UNDERWRITTEN OFFERINGS

      No Holder may participate in any underwritten offering under Section 3.1
unless such Holder (i) agrees to sell its Registrable Securities on the basis
provided in any underwriting arrangements approved, subject to the terms and
conditions hereof, by the Holders of a majority of Registrable Securities to be
included in such underwritten offering, and (ii) completes and executes all
questionnaires, indemnities, underwriting agreements and other documents (other
than powers of attorney) required under the terms of such underwriting
arrangements. Notwithstanding the foregoing, no underwriting agreement (or other
agreement in connection with such offering) will require any Holder to make a
representation or warranty to or agreement with the Company or the underwriters
other than, in a writing furnished by such Holder expressly for use in the
related registration statement, regarding such Holder, such Holder's Registrable
Securities, such Holder's intended method of distribution, and any other
representation, warranty or agreement otherwise required by law.

                                    ARTICLE 6
                                 INDEMNIFICATION

      6.1 INDEMNIFICATION BY THE COMPANY. In the event of any registration of
any securities of the Company under the 1933 Act, the Company will, and hereby
does agree to indemnify and hold harmless the Holder of any Registrable
Securities covered by such registration statement, 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 such Holder or any such underwriter
within the meaning of the 1933 Act, against any losses, claims, damages, or
liabilities ("LOSSES") to which such Holder 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 such Holder 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 such Holder
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 such Holder or any such underwriter or
controlling person and will survive the transfer of such securities by such
Holder.

      6.2 INDEMNIFICATION BY THE HOLDER. The Company may require, as a condition
to including any Registrable Securities in any registration statement filed
pursuant to this Agreement, that the Company have received an undertaking
satisfactory to it from the Holder of such Registrable Securities, to indemnify
and hold harmless (in the same manner and to the same extent as set forth in
Section 6.1) 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 such
Holder 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 such Holder. The liability of a
Holder under this Section 6.1 will be limited to the net proceeds from the
offering received by such Holder.

                                       6
<PAGE>

      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 Section 6.1 or Section 6.1, 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 Section 6.1 or Section
6.1, 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
Section 6.1 and Section 6.1 (with appropriate modifications) will be given by
the Company and each Holder of Registrable Securities (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 Sections 6.1
and 6.1 will 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.

                                    RULE 144

      The Company will use commercially reasonable best efforts to timely file
the reports required to be filed by it under the 1933 Act, the Securities
Exchange Act of 1934, and the rules and regulations adopted by the SEC
thereunder (or, if the Company is not required to file such reports, will, upon
the request of any Holder make information publicly available) to the extent
required from time to time to enable such Holder to sell Registrable Securities
without registration under the 1933 Act within the limitation of the exemptions
provided by (a) Rule 144 under the 1933 Act, as such Rule may be amended from
time to time, or (b) any similar rule or regulation hereafter adopted by the
SEC. Upon the written request of any Holder, the Company will deliver to such
Holder a written statement as to whether it has complied with the requirements
of this Article 7.

                                   ARTICLE 8

      8.1 AMENDMENTS AND WAIVERS. This Agreement may be amended and the Company
may take any action herein prohibited, or omit to perform any act herein
required to be performed by it, only if the Company will have obtained the
approval of such amendment, action or omission to act, by the vote or consent,
either in writing or at a meeting, of Holders of at least two-thirds (2/3) of
the Registrable Securities issued and issuable at such time. Each Holder of any
Registrable Securities at the time or thereafter outstanding will be bound by
any consent authorized by this Section 8.1, whether or not such Registrable
Securities will have been marked to indicate such consent.

      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

      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 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.

                               WARRANT TO PURCHASE

                             SHARES OF COMMON STOCK

                              Expires April 8, 2015

                                                                Portland, Oregon
                                              Original Issue Date: April 8, 2005

      IN CONSIDERATION OF $1,000.00, the representations and covenants set forth
herein, and other good and valuable  consideration  received, and subject to the
provisions hereinafter set forth,  microHelix,  Inc., an Oregon corporation (the
"Company"), hereby certifies that  ____________________________or its registered
assigns (the "Warrant Holder") is entitled to subscribe for and purchase, during
the period specified in this Warrant,  up to [xxx,xxx] shares ("Warrant Shares")
(subject to adjustment as hereinafter provided) of the duly authorized,  validly
issued,  fully  paid  and  non-assessable  Common  Stock of the  Company,  at an
exercise  price per share  equal to $0.25 per share  (subject to  adjustment  as
hereinafter provided, the "Exercise Price") subject,  however, to the provisions
and upon the terms and conditions  hereinafter set forth.  The right to purchase
Warrant Shares will expire at 12:01 a.m., Pacific Time, on April 8, 2015.

<PAGE>

      1.  Registration  of Warrant.  The Company will register this Warrant upon
records  to be  maintained  by  the  Company  for  that  purpose  (the  "Warrant
Register"),  in the name of the record  Warrant Holder hereof from time to time.
The Company may deem and treat the registered  Warrant Holder of this Warrant as
the  absolute  owner  hereof  for the  purpose  of any  exercise  hereof  or any
distribution to the Warrant Holder, and for all other purposes,  and the Company
will not be affected by notice to the contrary.

      2.  Representations  and Covenants of the Warrant Holder. This Warrant has
been entered into by the Company in reliance upon the following  representations
and covenants of the Warrant Holder:

            (a) The Warrant Holder by accepting this Warrant represents that the
Warrant  Holder is acquiring  this Warrant for its own account or the account of
an affiliate  for  investment  purposes and not with the view to any offering or
distribution  and that the Warrant Holder will not sell or otherwise  dispose of
this  Warrant  or the  underlying  Warrant  Shares in  violation  of  applicable
securities laws.

            (b)  The  Warrant   Holder   acknowledges   that  the   certificates
representing any Warrant Shares will bear a legend indicating that they have not
been registered under the United States  Securities Act of 1933, as amended (the
"1933 Act"),  and may not be sold by the Warrant  Holder  except  pursuant to an
effective  registration  statement or pursuant to an exemption from registration
requirements of the 1933 Act and in accordance with federal and state securities
laws.

            (c) In no event will the Warrant Holder make a disposition of any of
its rights to acquire  Common Stock or Common Stock  issuable  upon  exercise of
such rights  unless and until (i) it has  notified  the Company of the  proposed
disposition,  and (ii) if requested by the Company, it has furnished the Company
with an opinion of counsel  satisfactory  to the  Company and its counsel to the
effect that (A)  appropriate  action  necessary for compliance with the 1933 Act
has been taken,  or (B) an exemption from the  registration  requirements of the
1933 Act is available.  Notwithstanding  the foregoing,  the restrictions on the
transferability of any security will terminate when such security is effectively
registered  under the 1933 Act and sold by the holder thereof in accordance with
such registration,  or such security is sold without  registration in compliance
with Rule 144 under the 1933 Act.  Whenever the restrictions  imposed under this
section terminate,  the Warrant Holder or holder of a share of Common Stock then
outstanding as to which such  restrictions  have  terminated will be entitled to
receive  from the  Company one or more new  certificates  for the Warrant or for
such shares of Common Stock not bearing any restrictive legend.

            (d) The  Warrant  Holder  is an  "accredited  investor"  within  the
meaning of Rule 501(a) of Regulation D promulgated under the 1933 Act.

            (e)  The  Warrant  Holder  has  such  knowledge  and  experience  in
financial  and business  matters as to be capable of  evaluating  the merits and
risks of its  investment,  and has the ability to bear the economic risks of its
investment.

                                       2
<PAGE>

            (f) The Warrant Holder understands that if a registration  statement
covering  the this  Warrant or the Common Stock if not in effect when it desires
to sell this  Warrant  or the  Common  Stock,  it may be  required  to hold such
securities for an indefinite  period.  The Warrant Holder also  understands that
any sale of its rights to purchase  Common  Stock or Common Stock which might be
made by it in  reliance  upon  Rule 144  under  the 1933 Act may be made only in
accordance with the terms and conditions of that Rule.

      3.  Validity of Warrant and Issue of Shares.  The Company  represents  and
warrants  that this  Warrant has been duly  authorized  and  validly  issued and
warrants  and  agrees  that all of  Common  Stock  that may be  issued  upon the
exercise of the rights  represented by this Warrant will,  when issued upon such
exercise,  be duly authorized,  validly issued, fully paid and nonassessable and
free from all taxes,  liens and charges with respect to the issue  thereof.  The
Company  further  warrants  and agrees that during the period  within  which the
rights  represented  by this Warrant may be  exercised,  the Company will at all
times have  authorized  and  reserved  a  sufficient  number of Common  Stock to
provide for the exercise of the rights represented by this Warrant.

      4.  Registration  of Transfers of Warrant.  Subject to compliance with the
legend set forth on the face of this Warrant and Section 2(c),  the Company will
register  the  transfer  of any  portion of this  Warrant in the  Warrant in the
Warrant  Register,  upon  surrender of this Warrant with the Form of  Assignment
attached  hereto  duly  completed  and  signed,  to the  Company.  Upon any such
registration   or  transfer,   a  new  warrant  to  purchase  Common  Stock,  in
substantially the form of this Warrant (any such new warrant,  a "New Warrant"),
evidencing  the  portion of this  Warrant so  transferred  will be issued to the
transferee and a New Warrant  evidencing  the remaining  portion of this Warrant
not so transferred,  if any, will be issued to the transferring  Warrant Holder.
The acceptance of the New Warrant by the  transferee  thereof will be deemed the
acceptance of such  transferee of all of the rights and obligations of a Warrant
Holder of a Warrant.

      5. Exercise of Warrants.

            (a) Upon  surrender  of this  Warrant  with the Form of  Election to
Purchase  attached  hereto duly  completed  and signed to the Company,  and upon
payment and delivery of the Exercise  Price per Warrant Share  multiplied by the
number of Warrant Shares that the Warrant Holder intends to purchase  hereunder,
in lawful  money of the United  States of America,  in cash or by  certified  or
official bank check or checks,  to the Company,  all as specified by the Warrant
Holder in the Form of Election to Purchase,  the Company will promptly  issue or
cause to be issued and cause to be delivered to or upon the written order of the
Warrant  Holder and in such name or names as the  Warrant  Holder may  designate
(subject to the  restrictions  on  transfer  described  Section  2(c) and in the
legend set forth on the face of this  Warrant),  a  certificate  for the Warrant
Shares issuable upon such exercise,  with such restrictive legend as required by
the 1933 Act. Any person so designated by the Holder to receive  Warrant  Shares
will be deemed to have become the holder of record of such Warrant  Shares as of
the Date of Exercise of this Warrant.

            (b) A "Date of  Exercise"  means the date on which the Company  will
have  received (i) this Warrant (or any New Warrant,  as  applicable),  with the
Form of Election to Purchase  attached  hereto (or attached to such New Warrant)
appropriately  completed and duly signed, and (ii) payment of the Exercise Price
for  the  number  of  Warrant  Shares  indicated  by the  Warrant  Holder  to be
purchased.

                                       3
<PAGE>

            (c) If less than all of the Warrant  Shares  which may be  purchased
under this Warrant are exercised at any time, the Company will issue or cause to
be issued a New Warrant evidencing the right to purchase the remaining number of
Warrant Shares.

            (d) After  April 8,  2006 the  holder of this  Warrant  may,  at its
election,  exercise  this Warrant in whole or in part and, in lieu of making the
cash payment otherwise contemplated to be made to the Company upon such exercise
in payment of the aggregate  Exercise Price,  elect instead to receive upon such
exercise the "Net Number" of shares of Common Stock determined  according to the
following formula (a "Cashless Exercise"):

                          Net Number = (A x (B - C))/B

                  (ii) For purposes of the foregoing formula:

                  A = the total number shares with respect to which this Warrant
                  is then being exercised.

                  B = the  average  Market  Price  (as  defined  below)  over  a
                  twenty-one  (21) day period  ending three  trading days before
                  the effective date of the Exercise Notice.

                  C = the Warrant  Exercise  Price then in effect at the time of
                  such exercise.

"Market  Price"  means,  with respect to Warrant  Shares,  if (i) the shares are
listed or admitted for listing on any national  securities  exchange or included
in The Nasdaq National Market or the Nasdaq SmallCap  Market,  the last reported
sales price as reported on such  exchange or market;  (ii) if the shares are not
so listed or admitted for trading,  the average of the last reported closing bid
and asked  quotation for the shares as reported on the National  Association  of
Securities Dealers Automated Quotation System ("NASDAQ") or a similar service if
NASDAQ is not  reporting  such  information;  or (iii) if the  shares are not so
listed or  admitted  for trading or quoted by NASDAQ or a similar  service,  the
average of the last reported bid and asked quotation for the shares as quoted by
a market  maker in the shares (or if there is more than one market  maker,  then
the average of the lowest bid and highest  asked  quotation).  In the absence of
any available  public  quotations for the shares,  the Board of Directors of the
Company will determine in good faith the fair market value of the shares,  which
determination  will be set forth in a certificate signed by the Secretary of the
Company.

      6. Adjustment of Exercise Price and Number of Shares. The character of the
shares of stock or other  securities  at the time issuable upon exercise of this
Warrant,  the number of Warrant  Shares,  and the Exercise  Price are subject to
adjustment upon the occurrence of the following events, and all such adjustments
will be cumulative:

            (a) The  Exercise  Price of this Warrant and the number of shares of
Common Stock or other  securities  at the time  issuable  upon  exercise of this
Warrant  will be  appropriately  adjusted to reflect any stock  dividend,  stock
split,  combination  of  shares,  reclassification,  recapitalization  or  other
similar event affecting the number of outstanding shares of stock or securities.

                                       4
<PAGE>

            (b) In case of any  consolidation  or merger of the Company  with or
into  any  other   corporation,   entity  or  person,  or  any  other  corporate
reorganization,  in which the Company  will not be the  continuing  or surviving
entity of such  consolidation,  merger or  reorganization  (any such transaction
being hereinafter  referred to as a  "Reorganization"),  then, in each case, the
holder of this  Warrant,  on  exercise  at any time  after the  consummation  or
effective date of such  Reorganization  (the "Effective Date"), will receive, in
lieu of the shares of stock or other  securities  at any time  issuable upon the
exercise of the Warrant  issuable on such exercise prior to the Effective  Date,
the stock and other  securities  and  property  (including  cash) to which  such
holder  would have been  entitled  upon the  Effective  Date if such  holder had
exercised  this  Warrant  immediately  prior  thereto  (all  subject  to further
adjustment as provided in this Warrant).

            (c) In case of any adjustment or  readjustment  in the price or kind
of  securities  issuable on the  exercise  of this  Warrant,  the  Company  will
promptly  give written  notice  thereof to the holder of this  Warrant,  setting
forth such adjustment or readjustment and showing in reasonable detail the facts
upon which such adjustment or readjustment is based.

      7. Fractional  Shares.  The Company will not be required to issue or cause
to be issued  fractional  Warrant  Shares on the exercise of this  Warrant.  The
number of full  Warrant  Shares that will be issuable  upon the exercise of this
Warrant will be computed on the basis of the aggregate number of Warrants Shares
purchasable  on  exercise of this  Warrant so  presented.  If any  fraction of a
Warrant Share would, except for the provisions of this Section 7, be issuable on
the exercise of this Warrant, the Company will, at its option, (i) pay an amount
in cash equal to the Exercise  Price  multiplied  by such fraction or (ii) round
the number of Warrant Shares issuable, up to the next whole number.

      8.  Sale  or  Merger  of the  Company.  In the  event  of a sale of all or
substantially all of the assets of the Company or the merger or consolidation of
the Company in a transaction  in which the Company is not the surviving  entity,
Warrant Holder will have the right to exercise the warrants  concurrent with the
sale.

      9. Notice of Intent to Sell or Merge the  Company.  The Company  will give
Warrant Holder 30 days notice before the event of a sale of all or substantially
all of the assets of the Company or the merger or  consolidation  of the Company
in a transaction in which the Company is not the surviving entity.

      10. Right To Include ("Piggy-Back") Registration Rights.

                  (a) Provided that the Warrant  Shares are not then  registered
if, at any time  prior to the date all  Warrant  Shares  may be sold by  Warrant
Holder pursuant to Rule 144 under the 1933 Act, the Company proposes to register
shares of its  Common  Stock  under the 1933 Act (other  than by a  registration
which would not permit  registration  of such securities for sale to the public,
on Form S-8, or any  successor  form  thereto,  or on Form S-4, or any successor
form thereto) on an underwritten basis (either best-efforts or firm-commitment),
the Company will each such time give prompt written notice to the Warrant Holder
of its  intention to register its  securities.  Upon the written  request of the
Warrant  Holder  made  within  fifteen  (15) days after the  receipt of any such
notice from the Company (which request will specify the number of Warrant Shares
intended to be disposed of by such  Warrant  Holder and the  intended  method of
disposition  thereof),  the Company will,  subject to the terms of this Warrant,
use its  commercially  reasonable best efforts to include such Warrant Shares in
the  registration  statement  which  covers  the  securities  which the  Company
proposes to register.

                                       5
<PAGE>

            (b) 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 Warrant  Holder.  In the
case of a  determination  not to  register,  the Company will be relieved of the
obligation to register any Warrant Shares in connection with such registration.

            (c) The Company  will pay all  registration  expenses in  connection
with each  registration  of Warrant Shares  requested  pursuant to this Section,
except the Warrant  Holder  will pay its pro rata  portion of the  discounts  or
commissions payable to any underwriter.

            (d)  If  the  managing  underwriter  of  the  underwritten  offering
contemplated  by this Section  informs the Company and Warrant Holder in writing
that it 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 Warrant  Shares
which the  Company is advised by the  managing  underwriter  can be sold in such
offering,   after  taking  into  account  Company's  obligations  to  its  other
securities holders with registration rights.

      11.  Notices.  All notices and other  communications  hereunder will be in
writing and will be deemed to have been given (i) on the date they are delivered
if  delivered  in person;  (ii) on the date  initially  received if delivered by
facsimile  transmission  followed by registered or certified mail  confirmation;

      12. Miscellaneous.

            (a) This  Warrant  constitutes  the  entire  agreement  between  the
Company  and Warrant  Holder with  respect to the  subject  matter  hereof,  and
supersedes all prior agreements between the parties with respect to such subject
matter.  This Warrant will be binding on and inure to the benefit of the parties
hereto and their respective  successors and permitted assigns.  This Warrant may
be amended only in a writing signed by the Company and the Warrant Holder.

            (b) Nothing in this  Warrant will be construed to give to any person
or  corporation  other  than the  Company  and the  Warrant  Holder any legal or
equitable right, remedy or cause of action under this Warrant; this Warrant will
be for the sole and exclusive benefit of the Company and the Warrant Holder.

            (c) This  Warrant  will be governed  by,  construed  and enforced in
accordance  with the internal laws of the State of Oregon  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  Warrant,  and hereby waive any objection to venue in any such
court and any claim that such forum is an inconvenient forum.

            (d) Each party hereby  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  Warrant or any
transaction  contemplated  hereby. In the event suit or action is brought by any
party  under  this  Warrant  to  enforce  any of  its  terms,  or in any  appeal
therefrom, it is agreed that the prevailing party or parties will be entitled to
reasonable  attorneys fees to be fixed by the  arbitrator,  trial court,  and/or
appellate court.

            (e) The parties  agree that a breach or  violation  of this  Warrant
will result in immediate and irreparable harm to the  non-breaching  party 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  party.  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.

            (f) The headings herein are for convenience  only, do not constitute
a part of this  Warrant  and will not be deemed  to limit or  affect  any of the
provisions hereof.

            (g) In case any one or more of the  provisions  of this Warrant will
be invalid or unenforceable in any respect,  the validity and  enforceability of
the  remaining  terms  and  provisions  of this  Warrant  will not in any way be
affected or impaired thereby and the parties will attempt in good faith to agree
upon a valid and enforceable  provision which will be a commercially  reasonably
substitute  therefore,  and upon so agreeing,  will  incorporate such substitute
provision in this Warrant.

                                       7
<PAGE>

            (h) The Warrant  Holder will not, by virtue  hereof,  be entitled to
any voting or other rights of a  shareholder  of the  Company,  either at law or
equity,  and the rights of the Warrant Holder are limited to those  expressed in
this Warrant.

            (i) This Warrant 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 Warrant will be legal and binding on all parties hereto.

         IN  WITNESS  WHEREOF,  each party has  caused  this  Warrant to be duly
executed by its authorized officer effective as of the Original Issue Date.
