                                WARRANT AGREEMENT



                                     between



                                microHELIX, INC.

                          MELLON INVESTOR SERVICES LLC



                          Dated as of ________ _, 2001



<PAGE>   2

      This Agreement, dated as of __________ _, 2001, is between microHelix,
Inc., an Oregon corporation (the "Company") and Mellon Investor Services LLC, a
____________ limited liability company, (the "Warrant Agent").

      The Company, at or about the time that it is entering into this Agreement,
proposes to issue and sell to public investors up to 1,725,000 Units ("Units").
Each Unit consists of one share of Common Stock of the Company ("Common Stock")
and one Warrant (collectively, the "Warrants"), each Warrant exercisable to
purchase one share of Common Stock for the Exercise Price (hereinafter defined)
upon the terms and conditions and subject to adjustment in certain
circumstances, all as set forth in this Agreement.

      The Company proposes to issue to its counsel an additional 15,625 units
and to the Representative of the Underwriters in the public offering of Units
referred to above warrants to purchase up to 150,000 additional Units.

      The Company wishes to retain the Warrant Agent to act on behalf of the
Company, and the Warrant Agent is willing so to act, in connection with the
issuance, transfer, exchange and replacement of the certificates evidencing the
Warrants to be issued under this Agreement (the "Warrant Certificates") and the
exercise of the Warrants;

      The Company and the Warrant Agent wish to enter into this Agreement to set
forth the terms and conditions of the Warrants and the rights of the holders
thereof ("Warrantholders") and to set forth the respective rights and
obligations of the Company and the Warrant Agent. Each Warrantholder is an
intended beneficiary of this Agreement with respect to the rights of
Warrantholders herein.

      NOW, THEREFORE, in consideration of the premises and the mutual agreements
herein set forth, the parties hereto agree as follows:

Section 1. Appointment of Warrant Agent

      The Company appoints the Warrant Agent to act as agent for the Company in
accordance with the instructions in this Agreement and the Warrant Agent accepts
such appointment.

Section 2. Date, Denomination and Execution of Warrant Certificates

      The Warrant Certificates (and the Form of Election to Purchase and the
Form of Assignment to be printed on the reverse thereof) shall be in registered
form only and shall be substantially of the tenor and purport recited in Exhibit
A hereto, and may have such letters, numbers or other marks of identification or
designation and such legends, summaries or endorsements printed, lithographed or
engraved thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any
law, or with any rule or regulation made pursuant thereto, or with any rule or
regulation of any stock exchange on which the Common Stock or the Warrants may
be listed or any automated quotation system, or to conform to usage. Each
Warrant Certificate shall entitle the registered holder thereof, subject to the
provisions of this Agreement and of the Warrant Certificate, to purchase, on or
before the close of business on __________ , 2006 (the "Expiration Date"), one
fully paid and non-assessable share of Common Stock for each Warrant evidenced
by such Warrant Certificate, for $___ , subject to adjustments as provided in
Sections 6 hereof, at any time on or before ____________ _, 2001 (the "Exercise
Price"). Each Warrant Certificate issued as a part of a Unit offered to the
public as described in the recitals, above, shall be dated _______ __, 2001;
each other Warrant Certificate shall be



                                       2
<PAGE>   3

dated the date on which the Warrant Agent receives valid issuance instructions
from the Company or a transferring holder of a Warrant Certificate or, if such
instructions specify another date, such other date.

      For purposes of this Agreement, the term "close of business" on any given
date shall mean 5:00 p.m., Pacific time, on such date; provided, however, that
if such date is not a business day, it shall mean 5:00 p.m., Pacific time, on
the next succeeding business day. For purposes of this Agreement, the term
"business day" shall mean any day other than a Saturday, Sunday, or a day on
which banking institutions in Portland, Oregon are authorized or obligated by
law to be closed.

      Each Warrant Certificate shall be executed on behalf of the Company by the
Chairman of the Board or its President or a Vice President, either manually or
by facsimile signature printed thereon, and have affixed thereto the Company's
seal or a facsimile thereof which shall be attested by the Secretary or an
Assistant Secretary of the Company, either manually or by facsimile signature.
Each Warrant Certificate shall be manually countersigned by the Warrant Agent
and shall not be valid for any purpose unless so countersigned. In case any
officer of the Company who shall have signed any Warrant Certificate shall cease
to be such officer of the Company before countersignature by the Warrant Agent
and issue and delivery thereof by the Company, such Warrant Certificate,
nevertheless, may be countersigned by the Warrant Agent, issued and delivered
with the same force and effect as though the person who signed such Warrant
Certificate had not ceased to be such officer of the Company.

Section 3. Subsequent Issue of Warrant Certificates

      Subsequent to their original issuance, no Warrant Certificates shall be
reissued except (i) Warrant Certificates issued upon transfer thereof in
accordance with Section 4 hereof, (ii) Warrant Certificates issued upon any
combination, split-up or exchange of Warrant Certificates pursuant to Section 4
hereof, (iii) Warrant Certificates issued in replacement of mutilated,
destroyed, lost or stolen Warrant Certificates pursuant to Section 5 hereof,
(iv) Warrant Certificates issued upon the partial exercise of Warrant
Certificates pursuant to Section 7 hereof, and (v) Warrant Certificates issued
to reflect any adjustment or change in the Exercise Price or the number or kind
of shares purchasable thereunder pursuant to Section 22 hereof. The Warrant
Agent is hereby irrevocably authorized to countersign and deliver, in accordance
with the provisions of said Sections 4, 5, 7 and 22, the new Warrant
Certificates required for purposes thereof, and the Company, whenever required
by the Warrant Agent, will supply the Warrant Agent with Warrant Certificates
duly executed on behalf of the Company for such purposes.

Section 4. Transfers and Exchanges of Warrant Certificates



                                       3
<PAGE>   4

      The Warrant Agent will keep or cause to be kept books for registration of
ownership and transfer of the Warrant Certificates issued hereunder. Such
registers shall show the names and addresses of the respective holders of the
Warrant Certificates and the number of Warrants evidenced by each such Warrant
Certificate.

      The Warrant Agent shall, from time to time, register the transfer of any
outstanding Warrants upon the books to be maintained by the Warrant Agent for
that purpose, upon surrender of the Warrant Certificate evidencing such
Warrants, with the Form of Assignment duly filled in and executed with such
signature guaranteed by a banking institution or NASD member and such supporting
documentation as the Warrant Agent or the Company may reasonably require, to the
Warrant Agent at its stock transfer office in __________, Oregon at any time on
or before the Expiration Date, and upon payment to the Warrant Agent for the
account of the Company of an amount equal to any applicable transfer tax.
Payment of the amount of such tax may be made in cash, or by certified or
official bank check, payable in lawful money of the United States of America to
the order of the Company.

      Upon receipt of a Warrant Certificate, with the Form of Assignment duly
filled in and executed, accompanied by payment of an amount equal to any
applicable transfer tax, the Warrant Agent shall promptly cancel the surrendered
Warrant Certificate and countersign and deliver to the transferee a new Warrant
Certificate for the number of full Warrants transferred to such transferee;
provided, however, that in case the registered holder of any Warrant Certificate
shall elect to transfer fewer than all of the Warrants evidenced by such Warrant
Certificate, the Warrant Agent in addition shall promptly countersign and
deliver to such registered holder a new Warrant Certificate or Certificates for
the number of full Warrants not so transferred.

      Any Warrant Certificate or Certificates may be exchanged at the option of
the holder thereof for another Warrant Certificate or Certificates of different
denominations, of like tenor and representing in the aggregate the same number
of Warrants, upon surrender of such Warrant Certificate or Certificates, with
the Form of Assignment duly filled in and executed, to the Warrant Agent, at any
time or from time to time after the close of business on the date hereof and
prior to the close of business on the Expiration Date. The Warrant Agent shall
promptly cancel the surrendered Warrant Certificate and deliver the new Warrant
Certificate pursuant to the provisions of this Section.

Section 5. Mutilated, Destroyed, Lost or Stolen Warrant Certificates

      Upon receipt by the Company and the Warrant Agent of evidence reasonably
satisfactory to them of the loss, theft, destruction or mutilation of any
Warrant Certificate, and in the case of loss, theft or destruction, of indemnity
or security reasonably satisfactory to them, and reimbursement to them of all
reasonable expenses incidental thereto, and, in the case of mutilation, upon
surrender and cancellation of the Warrant Certificate, the Warrant Agent shall
countersign and deliver a new Warrant Certificate of like tenor for the same
number of Warrants.

Section 6. Adjustments of Number and Kind of Shares Purchasable and Exercise
Price

      The number and kind of securities or other property purchasable upon
exercise of a Warrant shall be subject to adjustment from time to time upon the
occurrence, after the date hereof, of any of the following events:

   A. In case the Company shall (1) pay a dividend in, or make a distribution
of, shares of capital stock on its outstanding Common Stock, (2) subdivide its
outstanding shares of Common Stock into a greater number of such shares or (3)
combine its outstanding shares of Common Stock into a smaller number of such
shares, the total number of shares of Common Stock purchasable upon the exercise
of each Warrant outstanding immediately prior thereto shall be adjusted so that
the holder of any Warrant Certificate thereafter surrendered for exercise shall
be entitled to receive at the same aggregate Exercise Price the number of shares
of capital stock (of one or more classes) which such holder would have owned or
have been entitled to receive immediately following the happening of any of the
events described above had such Warrant been exercised in full immediately prior
to the record date with respect to such event. Any adjustment made pursuant to
this Subsection shall, in the case of a stock dividend or distribution, become
effective as of the record date therefor and, in the case of a subdivision or
combination, be



                                       4
<PAGE>   5

made as of the effective date thereof. If, as a result of an adjustment made
pursuant to this Subsection, the holder of any Warrant Certificate thereafter
surrendered for exercise shall become entitled to receive shares of two or more
classes of capital stock of the Company, the Board of Directors of the Company
(whose determination shall be conclusive and shall be evidenced by a Board
resolution filed with the Warrant Agent) shall determine the allocation of the
adjusted Exercise Price between or among shares of such classes of capital
stock.

   B. In the event of a capital reorganization or a reclassification of the
Common Stock (except as provided in Subsection A. above or Subsection E. below),
any Warrantholder, upon exercise of Warrants, shall be entitled to receive, in
substitution for the Common Stock to which he would have become entitled upon
exercise immediately prior to such reorganization or reclassification, the
shares (of any class or classes) or other securities or property of the Company
(or cash) that he would have been entitled to receive at the same aggregate
Exercise Price upon such reorganization or reclassification if such Warrants had
been exercised immediately prior to the record date with respect to such event;
and in any such case, appropriate provision (as determined by the Board of
Directors of the Company, whose determination shall be conclusive and shall be
evidenced by a certified Board resolution filed with the Warrant Agent) shall be
made for the application of this Section 6 with respect to the rights and
interests thereafter of the Warrantholders (including but not limited to the
allocation of the Exercise Price between or among shares of classes of capital
stock), to the end that this Section 6 (including the adjustments of the number
of shares of Common Stock or other securities purchasable and the Exercise Price
thereof) shall thereafter be reflected, as nearly as reasonably practicable, in
all subsequent exercises of the Warrants for any shares or securities or other
property (or cash) thereafter deliverable upon the exercise of the Warrants.

   C. Whenever the number of shares of Common Stock or other securities
purchasable upon exercise of a Warrant is adjusted as provided in this Section
6, the Company will promptly file with the Warrant Agent a certificate signed by
a Chairman or co-Chairman of the Board or the President or a Vice President of
the Company and by the Treasurer or an Assistant Treasurer or the Secretary or
an Assistant Secretary of the Company setting forth the number and kind of
securities or other property purchasable upon exercise of a Warrant, as so
adjusted, stating that such adjustments in the number or kind of shares or other
securities or property conform to the requirements of this Section 6, and
setting forth a brief statement of the facts accounting for such adjustments.
Promptly after receipt of such certificate, the Company, or the Warrant Agent at
the Company's request, will deliver, by first-class, postage prepaid mail, a
brief summary thereof (to be supplied by the Company) to the registered holders
of the outstanding Warrant Certificates; provided, however, that failure to file
or to give any notice required under this Subsection, or any defect therein,
shall not affect the legality or validity of any such adjustments under this
Section 6; and provided, further, that, where appropriate, such notice may be
given in advance and included as part of the notice required to be given
pursuant to Section 12 hereof.

   D. In case of any consolidation of the Company with, or merger of the Company
into, another corporation (other than a consolidation or merger which does not
result in any reclassification or change of the outstanding Common Stock), or in
case of any sale or conveyance to another corporation of the property of the
Company as an entirety or substantially as an entirety, the corporation formed
by such consolidation or merger or the corporation which shall have acquired
such assets, as the case may be, shall execute and deliver to the Warrant Agent
a supplemental warrant agreement providing that the holder of each Warrant then
outstanding shall have the right thereafter (until the expiration of such
Warrant) to receive, upon exercise of such Warrant, solely the kind and amount
of shares of stock and other securities and property (or cash) receivable upon
such consolidation, merger, sale or transfer by a holder of the number of shares
of Common Stock of the Company for which such Warrant might have been exercised
immediately prior to such consolidation, merger, sale or transfer. Such
supplemental warrant agreement shall provide for adjustments which shall be as
nearly equivalent as may be practicable to the adjustments provided in this
Section. The above provision of this Subsection shall similarly apply to
successive consolidations, mergers, sales or transfers.

      The Warrant Agent shall not be under any responsibility to determine the
correctness of any provision contained in any such supplemental warrant
agreement relating to either the kind or amount of shares of stock or securities
or property (or cash) purchasable by holders of Warrant Certificates upon the
exercise of their Warrants after any such consolidation, merger, sale or
transfer or of any adjustment to be made with respect thereto, but



                                       5
<PAGE>   6

subject to the provisions of Section 20 hereof, may accept as conclusive
evidence of the correctness of any such provisions, and shall be protected in
relying upon, a certificate of a firm of independent certified public
accountants (who may be the accountants regularly employed by the Company) with
respect thereto.

   E. Irrespective of any adjustments in the number or kind of shares issuable
upon exercise of Warrants, Warrant Certificates theretofore or thereafter issued
may continue to express the same price and number and kind of shares as are
stated in the similar Warrant Certificates initially issuable pursuant to this
Warrant Agreement.

   F. The Company may retain a firm of independent public accountants of
recognized standing, which may be the firm regularly retained by the Company,
selected by the Board of Directors of the Company or the Executive Committee of
said Board, and not disapproved by the Warrant Agent, to make any computation
required under this Section, and a certificate signed by such firm shall, in the
absence of fraud or gross negligence, be conclusive evidence of the correctness
of any computation made under this Section.

   G. For the purpose of this Section, the term "Common Stock" shall mean (i)
the Common Stock or (ii) any other class of stock resulting from successive
changes or reclassifications of such Common Stock consisting solely of changes
in par value, or from par value to no par value, or from no par value to par
value. In the event that at any time as a result of an adjustment made pursuant
to this Section, the holder of any Warrant thereafter surrendered for exercise
shall become entitled to receive any shares of capital stock of the Company
other than shares of Common Stock, thereafter the number of such other shares so
receivable upon exercise of any Warrant shall be subject to adjustment from time
to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Common Stock contained in this Section, and all
other provisions of this Agreement, with respect to the Common Stock, shall
apply on like terms to any such other shares.

   H. The Company may, from time to time and to the extent permitted by law,
reduce the exercise price of the Warrants by any amount for a period of not less
than 20 days. If the Company so reduces the exercise price of the Warrants, it
will give not less than 15 days' notice of such decrease, which notice may be in
the form of a press release, and shall take such other steps as may be required
under applicable law in connection with any offers or sales of securities at the
reduced price.

Section 7. Exercise and Redemption of Warrants

      Unless the Warrants have been redeemed as provided in this Section 7, the
registered holder of any Warrant Certificate may exercise the Warrants evidenced
thereby, in whole at any time or in part from time to time at or prior to the
close of business, on the Expiration Date, subject to the provisions of Section
9, at which time the Warrant Certificates shall be and become wholly void and of
no value. Warrants may be exercised by their holders or redeemed by the Company
as follows:

   A. Exercise of Warrants shall be accomplished upon surrender of the Warrant
Certificate evidencing such Warrants, with the Form of Election to Purchase on
the reverse side thereof duly filled in and executed, to the Warrant Agent at
its stock transfer office in _________, Oregon, together with payment to the
Company of the Exercise Price (as of the date of such surrender) of the Warrants
then being exercised and an amount equal to any applicable transfer tax and, if
requested by the Company, any other taxes or governmental charges which the
Company may be required by law to collect in respect of such exercise. Payment
of the Exercise Price and other amounts may be made by wire transfer of good
funds, or by certified or bank cashier's check, payable in lawful money of the
United States of America to the order of the Company. No adjustment shall be
made for any cash dividends, whether paid or declared, on any securities
issuable upon exercise of a Warrant.

   B. Upon receipt of a Warrant Certificate, with the Form of Election to
Purchase duly filled in and executed, accompanied by payment of the Exercise
Price of the Warrants being exercised (and of an amount equal to any applicable
taxes or government charges as aforesaid), the Warrant Agent shall promptly
request from the Transfer Agent with respect to the securities to be issued and
deliver to or upon the order of the registered holder of such Warrant
Certificate, in such name or names as such registered holder may designate, a
certificate or certificates for



                                       6
<PAGE>   7

the number of full shares of the securities to be purchased, together with cash
made available by the Company pursuant to Section 8 hereof in respect of any
fraction of a share of such securities otherwise issuable upon such exercise. If
the Warrant is then exercisable to purchase property other than securities, the
Warrant Agent shall take appropriate steps to cause such property to be
delivered to or upon the order of the registered holder of such Warrant
Certificate. In addition, if it is required by law and upon instruction by the
Company, the Warrant Agent will deliver to each Warrantholder a prospectus which
complies with the provisions of Section 9 of the Securities Act of 1933 and the
Company agrees to supply Warrant Agent with sufficient number of prospectuses to
effectuate that purpose.

   C. In case the registered holder of any Warrant Certificate shall exercise
fewer than all of the Warrants evidenced by such Warrant Certificate, the
Warrant Agent shall promptly countersign and deliver to the registered holder of
such Warrant Certificate, or to his duly authorized assigns, a new Warrant
Certificate or Certificates evidencing the number of Warrants that were not so
exercised.

   D. Each person in whose name any certificate for securities is issued upon
the exercise of Warrants shall for all purposes be deemed to have become the
holder of record of the securities represented thereby as of, and such
certificate shall be dated, the date upon which the Warrant Certificate was duly
surrendered in proper form and payment of the Exercise Price (and of any
applicable taxes or other governmental charges) was made; provided, however,
that if the date of such surrender and payment is a date on which the stock
transfer books of the Company are closed, such person shall be deemed to have
become the record holder of such shares as of, and the certificate for such
shares shall be dated, the next succeeding business day on which the stock
transfer books of the Company are open (whether before, on or after the
Expiration Date) and the Warrant Agent shall be under no duty to deliver the
certificate for such shares until such date. The Company covenants and agrees
that it shall not cause its stock transfer books to be closed for a period of
more than 20 consecutive business days except upon consolidation, merger, sale
of all or substantially all of its assets, dissolution or liquidation or as
otherwise provided by law.

   E. The Warrants outstanding at the time of a redemption may be redeemed at
the option of the Company, in whole or in part on a pro-rata basis, at any time
after the Company has reported earnings for any fiscal year equal to or greater
than $0.60 per share, at a price equal to $0.25 per Warrant (the "Redemption
Price"). On the redemption date the holders of record of redeemed Warrants shall
be entitled to payment of the Redemption Price upon surrender of such redeemed
Warrants to the Company at the principal office of the Warrant Agent in
___________, Oregon.

   F. Notice of redemption of Warrants shall be given at least 30 days prior to
the redemption date by mailing, by registered or certified mail, return receipt
requested, a copy of such notice to the Warrant Agent and to all of the holders
of record of Warrants at their respective addresses appearing on the books or
transfer records of the Company or such other address designated in writing by
the holder of record to the Warrant Agent not less than 40 days prior to the
redemption date.

   G. From and after the redemption date, all rights of the Warrantholders
(except the right to receive the Redemption Price) shall terminate, but only if
(a) no later than one day prior to the redemption date the Company shall have
irrevocably deposited with the Warrant Agent as paying agent a sufficient amount
to pay on the redemption date the Redemption Price for all Warrants called for
redemption and (b) the notice of redemption shall have stated the name and
address of the Warrant Agent and the intention of the Company to deposit such
amount with the Warrant Agent no later than one day prior to the redemption
date.

   H. The Warrant Agent shall pay to the holders of record of redeemed Warrants
all monies received by the Warrant Agent for the redemption of Warrants to which
the holders of record of such redeemed Warrants who shall have surrendered their
Warrants are entitled.

   I. Any amounts deposited with the Warrant Agent that are not required for
redemption of Warrants may be withdrawn by the Company. Any amounts deposited
with the Warrant Agent that shall be unclaimed after six months after the
redemption date may be withdrawn by the Company, and thereafter the holders of
the Warrants



                                       7
<PAGE>   8

called for redemption for which such funds were deposited shall look solely to
the Company for payment. The Company shall be entitled to the interest, if any,
on funds deposited with the Warrant Agent and the holders of redeemed Warrants
shall have no right to any such interest.

   J. If the Company fails to make a sufficient deposit with the Warrant Agent
as provided above, the holder of any Warrants called for redemption may at the
option of the holder (a) by notice to the Company declare the notice of
redemption a nullity as to such holder, or (b) maintain an action against the
Company for the Redemption Price. If the holder brings such an action, the
Company will pay reasonable attorneys' fees of the holder. If the holder fails
to bring an action against the Company for the Redemption Price within 60 days
after the redemption date, the holder shall be deemed to have elected to declare
the notice of redemption to be a nullity as to such holder and such notice shall
be without any force or effect as to such holder. Except as otherwise
specifically provided in this Paragraph J, a notice of redemption, once mailed
by the Company as provided in Paragraph F shall be irrevocable.

Section 8. Fractional Interests

      The Company shall not be required to issue any Warrant Certificate
evidencing a fraction of a Warrant or to issue fractions of shares of securities
on the exercise of the Warrants. If any fraction (calculated to the nearest
one-hundredth) of a Warrant or a share of securities would, except for the
provisions of this Section, be issuable on the exercise of any Warrant, the
Company shall, at its option, either purchase such fraction for an amount in
cash equal to the current value of such fraction computed on the basis of the
closing market price (as quoted on NASDAQ) on the trading day immediately
preceding the day upon which such Warrant Certificate was surrendered for
exercise in accordance with Section 7 hereof or issue the required fractional
Warrant or share. By accepting a Warrant Certificate, the holder thereof
expressly waives any right to receive a Warrant Certificate evidencing any
fraction of a Warrant or to receive any fractional share of securities upon
exercise of a Warrant, except as expressly provided in this Section 8.

Section 9. Reservation of Equity Securities

      The Company covenants that it will at all times reserve and keep
available, free from any pre-emptive rights, out of its authorized and unissued
equity securities, solely for the purpose of issue upon exercise of the
Warrants, such number of shares of equity securities of the Company as shall
then be issuable upon the exercise of all outstanding Warrants ("Equity
Securities"). The Company covenants that all Equity Securities which shall be so
issuable shall, upon such issue, be duly authorized, validly issued, fully paid
and non-assessable.

      The Company covenants that if any equity securities, required to be
reserved for the purpose of issue upon exercise of the Warrants hereunder,
require registration with or approval of any governmental authority under any
federal or state law before such shares may be issued upon exercise of Warrants,
the Company will use all commercially reasonable efforts to cause such
securities to be duly registered, or approved, as the case may be, and, to the
extent practicable, take all such action in anticipation of and prior to the
exercise of the Warrants, including, without limitation, filing any and all
post-effective amendments to the Company's Registration Statement on Form SB-2
(Registration No. 333_____) necessary to permit a public offering of the
securities underlying the Warrants at any and all times during the term of this
Agreement, provided, however, that in no event shall such securities be issued,
and the Company is authorized to refuse to honor the exercise of any Warrant, if
such exercise would result in the opinion of the Company's Board of Directors,
upon advice of counsel, in the violation of any law; and provided further that,
in the case of a Warrant exercisable solely for securities listed on a
securities exchange or for which there are at least two independent market
makers, in lieu of obtaining such registration or approval, the Company may
elect to redeem Warrants submitted to the Warrant Agent for exercise for a price
equal to the difference between the aggregate low asked price, or closing price,
as the case may be, of the securities for which such Warrant is exercisable on
the date of such submission and the Exercise Price of such Warrants; in the
event of such redemption, the Company will pay to the holder of such Warrants
the above-described redemption price in cash within 10 business days after
receipt of notice from the Warrant Agent that such Warrants have been submitted
for exercise.



                                       8

Section 10. Reduction of Conversion Price Below Par Value

      Before taking any action that would cause an adjustment pursuant to
Section 6 hereof reducing the portion of the Exercise Price required to purchase
one share of capital stock below the then par value (if any) of a share of such
capital stock, the Company will use its best efforts to take any corporate
action which, in the opinion of its counsel, may be necessary in order that the
Company may validly and legally issue fully paid and non-assessable shares of
such capital stock.

Section 11. Payment of Taxes

      The Company covenants and agrees that it will pay when due and payable any
and all federal and state documentary stamp and other original issue taxes which
may be payable in respect of the original issuance of the Warrant Certificates,
or any shares of Common Stock or other securities upon the exercise of Warrants.
The Company shall not, however, be required (i) to pay any tax which may be
payable in respect of any transfer involved in the transfer and delivery of
Warrant Certificates or the issuance or delivery of certificates for Common
Stock or other securities in a name other than that of the registered holder of
the Warrant Certificate surrendered for purchase or (ii) to issue or deliver any
certificate for shares of Common Stock or other securities upon the exercise of
any Warrant Certificate until any such tax shall have been paid, all such tax
being payable by the holder of such Warrant Certificate at the time of
surrender.

Section 12. Notice of Certain Corporate Action

      In case the Company after the date hereof shall propose (i) to offer to
the holders of Common Stock, generally, rights to subscribe to or purchase any
additional shares of any class of its capital stock, any evidences of its
indebtedness or assets, or any other rights or options or (ii) to effect any
reclassification of Common Stock (other than a reclassification involving merely
the subdivision or combination of outstanding shares of Common Stock) or any
capital reorganization, or any consolidation or merger to which the Company is a
party and for which approval of any stockholders of the Company is required, or
any sale, transfer or other disposition of its property and assets substantially
as an entirety, or the liquidation, voluntary or involuntary dissolution or
winding-up of the Company, then, in each such case, the Company shall file with
the Warrant Agent and the Company, or the Warrant Agent on its behalf, shall
mail (by first-class, postage prepaid mail) to all registered holders of the
Warrant Certificates notice of such proposed action, which notice shall specify
the date on which the books of the Company shall close or a record be taken for
such offer of rights or options, or the date on which such reclassification,
reorganization, consolidation, merger, sale, transfer, other disposition,
liquidation, voluntary or involuntary dissolution or winding-up shall take place
or commence, as the case may be, and which shall also specify any record date
for determination of holders of Common Stock entitled to vote thereon or
participate therein and shall set forth such facts with respect thereto as shall
be reasonably necessary to indicate any adjustments in the Exercise Price and
the number or kind of shares or other securities purchasable upon exercise of
Warrants which will be required as a result of such action. Such notice shall be
filed and mailed in the case of any action covered by clause (i) above, at least

be deemed the holder of Common Stock or any other securities of the Company
which may at any time be issuable on the exercise of the Warrants represented
thereby for any purpose whatever, nor shall anything contained herein or in any
Warrant Certificate be construed to confer upon any Warrantholder, as such, any
of the rights of a stockholder of the Company or any right to vote for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action (whether
upon any recapitalization, issuance of stock, reclassification of stock, change
of par value or change of stock to no par value, consolidation, merger,
conveyance or otherwise), or to receive notice of meetings or other actions
affecting stockholders (except as provided in Section 12 hereof), or to receive
dividend or subscription rights, or otherwise, until such Warrant Certificate
shall have been exercised in accordance with the provisions hereof and the
receipt of the Exercise Price and any other amounts payable upon such exercise
by the Warrant Agent.

Section 15. Right of Action

      All rights of action in respect to this Agreement are vested in the
respective registered holders of the Warrant Certificates; and any registered
holder of any Warrant Certificate, without the consent of the Warrant Agent or
of any other holder of a Warrant Certificate, may, in his own behalf for his own
benefit, enforce, and may institute and maintain any suit, action or proceeding
against the Company suitable to enforce, or otherwise in respect of, his right
to exercise the Warrants evidenced by such Warrant Certificate, for the purchase
of shares of the Common Stock in the manner provided in the Warrant Certificate
and in this Agreement.

Section 16. Agreement of Holders of Warrant Certificates

      Every holder of a Warrant Certificate by accepting the same consents and
agrees with the Company, the Warrant Agent and with every other holder of a
Warrant Certificate that:

   A. the Warrant Certificates are transferable on the registry books of the
Warrant Agent only upon the terms and conditions set forth in this Agreement;
and

   B. the Company and the Warrant Agent may deem and treat the person in whose
name the Warrant Certificate is registered as the absolute owner of the Warrant
(notwithstanding any notation of ownership or other writing thereon made by
anyone other than the Company or the Warrant Agent) for all purposes whatever
and neither the Company nor the Warrant Agent shall be affected by any notice to
the contrary.

Section 17. Cancellation of Warrant Certificates

      In the event that the Company shall purchase or otherwise acquire any
Warrant Certificate or Certificates after the issuance thereof, such Warrant
Certificate or Certificates shall thereupon be delivered to the Warrant Agent
and be canceled by it and retired. The Warrant Agent shall also cancel any
Warrant Certificate delivered to it for exercise, in whole or in part, or
delivered to it for transfer, split-up, combination or exchange. Warrant
Certificates so canceled shall be delivered by the Warrant Agent to the Company
from time to time, or disposed of in accordance with the instructions of the
Company.

Section 18. Concerning the Warrant Agent

      The Company agrees to pay to the Warrant Agent from time to time, on
demand of the Warrant Agent, reasonable compensation for all services rendered
by it hereunder and also its reasonable expenses, including counsel fees, and
other disbursements incurred in the administration and execution of this
Agreement and the exercise and performance of its duties hereunder. The Company
also agrees to indemnify the Warrant Agent for, and to hold it harmless against,
any loss, liability or expense, incurred without gross negligence, bad faith or
willful misconduct on the part of the Warrant Agent, arising out of or in
connection with the acceptance and administration of this Agreement.

Section 19. Merger or Consolidation or Change of Name of Warrant Agent

      Any corporation into which the Warrant Agent may be merged or with which
it may be consolidated, or any corporation resulting from any merger or
consolidation to which the Warrant Agent shall be a party, or any corporation
succeeding to the corporate trust business of the Warrant Agent, shall be the
successor to the Warrant Agent hereunder without the execution or filing of any
paper or any further act on the part of any of the parties hereto, provided that
such corporation would be eligible for appointment as a successor warrant agent
under the provisions of Section 21 hereof. In case at the time such successor to
the Warrant Agent shall succeed to the agency created by this Agreement, any of
the Warrant Certificates shall have been countersigned but not delivered, any
such successor to the Warrant Agent may adopt the countersignature of the
original Warrant Agent and deliver such Warrant Certificates so countersigned;
and in case at that time any of the Warrant Certificates shall not have been
countersigned, any successor to the Warrant Agent may countersign such Warrant
Certificates either in the name of the predecessor Warrant Agent or in the name
of the successor Warrant Agent; and in all such cases such Warrant Certificates
shall have the full force provided in the Warrant Certificates and in this
Agreement.

      In case at any time the name of the Warrant Agent shall be changed and at
such time any of the Warrant Certificates shall have been countersigned but not
delivered, the Warrant Agent may adopt the countersignature under its prior name
and deliver Warrant Certificates so countersigned; and in case at that time any
of the Warrant Certificates shall not have been countersigned, the Warrant Agent
may countersign such Warrant Certificates either in its prior name or in its
changed name; and in all such cases such Warrant Certificates shall have the
full force provided in the Warrant Certificates and in this Agreement.

Section 20. Duties of Warrant Agent

      The Warrant Agent undertakes the duties and obligations imposed by this
Agreement upon the following terms and conditions, by all of which the Company
and the holders of Warrant Certificates, by their acceptance thereof, shall be
bound:

   A. The Warrant Agent may consult with counsel satisfactory to it (who may be
counsel for the Company or the Warrant Agent's in-house counsel), and the
opinion of such counsel shall be full and complete authorization and protection
to the Warrant Agent as to any action taken, suffered or omitted by it in good
faith and in accordance with such opinion; provided, however, that the Warrant
Agent shall have exercised reasonable care in the selection of such counsel.
Fees and expenses of such counsel, to the extent reasonable, shall be paid by
the Company.

   B. Whenever in the performance of its duties under this Agreement, the
Warrant Agent shall deem it necessary or desirable that any fact or matter be
proved or established by the Company prior to taking or suffering any action
hereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by a Chairman or co-Chairman of the Board or
the President or a Vice President or the Secretary of the Company and delivered
to the Warrant Agent; and such certificate shall be full authorization to the
Warrant Agent for any action taken or suffered in good faith by it under the
provisions of this Agreement in reliance upon such certificate.



                                       11
<PAGE>   12

   C. The Warrant Agent shall be liable hereunder only for its own gross
negligence, bad faith or willful misconduct.

   D. The Warrant Agent shall not be liable for or by reason of any of the
statements of fact or recitals contained in this Agreement or in the Warrant
Certificates (except its countersignature on the Warrant Certificates and such
statements or recitals as describe the Warrant Agent or action taken or to be
taken by it) or be required to verify the same, but all such statements and
recitals are and shall be deemed to have been made by the Company only.

   E. The Warrant Agent shall not be under any responsibility in respect of the
validity of this Agreement or the execution and delivery hereof (except the due
execution hereof by the Warrant Agent) or in respect of the validity or
execution of any Warrant Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or
condition contained in this Agreement or in any Warrant Certificate; nor shall
it be responsible for the making of any change in the number of shares of Common
Stock for which a Warrant is exercisable required under the provisions of
Section 6 or responsible for the manner, method or amount of any such change or
the ascertaining of the existence of facts that would require any such
adjustment or change (except with respect to the exercise of Warrant
Certificates after actual notice of any adjustment of the Exercise Price); nor
shall it by any act hereunder be deemed to make any representation or warranty
as to the authorization or reservation of any shares of Common Stock to be
issued pursuant to this Agreement or any Warrant Certificate or as to whether
any shares of Common Stock will, when issued, be validly issued, fully paid and
non-assessable.

   F. The Warrant Agent shall be under no obligation to institute any action,
suit or legal proceeding or take any other action likely to involve expense
unless the Company or one or more registered holders of Warrant Certificates
shall furnish the Warrant Agent with reasonable security and indemnity for any
costs and expenses which may be incurred. All rights of action under this
Agreement or under any of the Warrants may be enforced by the Warrant Agent
without the possession of any of the Warrants or the production thereof at any
trial or other proceeding relative thereto, and any such action, suit or
proceeding instituted by the Warrant Agent shall be brought in its name as
Warrant Agent, and any recovery of judgment shall be for the ratable benefit of
the registered holders of the Warrant Certificates, as their respective rights
or interests may appear.

   G. The Warrant Agent and any stockholder, director, officer or employee of
the Warrant Agent may buy, sell or deal in any of the Warrants or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to or
otherwise act as fully and freely as though it were not Warrant Agent under this
Agreement. Nothing herein shall preclude the Warrant Agent from acting in any
other capacity for the Company or for any other legal entity.

   H. The Warrant Agent is hereby authorized and directed to accept instructions
with respect to the performance of its duties hereunder from a Chairman or
co-Chairman of the Board or President or a Vice President or the Secretary or
the Controller of the Company, and to apply to such officers for advice or
instructions in connection with the Warrant Agent's duties, and it shall not be
liable for any action taken or suffered or omitted by it in good faith in
accordance with instructions of any such officer.

   I. The Warrant Agent will not be responsible for any failure of the Company
to comply with any of the covenants contained in this Agreement or in the
Warrant Certificates to be complied with by the Company.

   J. The Warrant Agent may execute and exercise any of the rights or powers
hereby vested in it or perform any duty hereunder either itself or by or through
its attorneys, agents or employees and the Warrant Agent shall not be answerable
or accountable for any act, default, neglect or misconduct of any such
attorneys, agents or employees or for any loss to the Company resulting from
such neglect or misconduct; provided, however, that reasonable care shall have
been exercised in the selection and continued employment of such attorneys,
agents and employees.

   K. The Warrant Agent will not incur any liability or responsibility to the
Company or to any holder of any Warrant Certificate for any action taken, or any
failure to take action, in reliance on any notice, resolution, waiver,



                                       12
<PAGE>   13

consent, order, certificate, or other paper, document or instrument reasonably
believed by the Warrant Agent to be genuine and to have been signed, sent or
presented by the proper party or parties.

   L. The Warrant Agent will act hereunder solely as agent of the Company in a
ministerial capacity, and its duties will be determined solely by the provisions
hereof. The Warrant Agent will not be liable for anything which it may do or
refrain from doing in connection with this Agreement except for its own
negligence, bad faith or willful conduct.

Section 21. Change of Warrant Agent

      The Warrant Agent may resign and be discharged from its duties under this
Agreement upon 30 days' prior notice in writing mailed, by registered or
certified mail, to the Company. The Company may remove the Warrant Agent or any
successor warrant agent upon 30 days' prior notice in writing, mailed to the
Warrant Agent or successor warrant agent, as the case may be, by registered or
certified mail. If the Warrant Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Warrant Agent and shall, within 15 days following such appointment, give
notice thereof in writing to each registered holder of the Warrant Certificates.
If the Company shall fail to make such appointment within a period of 15 days
after giving notice of such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Warrant Agent,
then the Company agrees to perform the duties of the Warrant Agent hereunder
until a successor Warrant Agent is appointed. After appointment and execution of
a copy of this Agreement in effect at that time, the successor Warrant Agent
shall be vested with the same powers, rights, duties and responsibilities as if
it had been originally named as Warrant Agent without further act or deed; but
the former Warrant Agent shall deliver and transfer to the successor Warrant
Agent, within a reasonable time, any property at the time held by it hereunder,
and execute and deliver any further assurance, conveyance, act or deed necessary
for the purpose. Failure to give any notice provided for in this Section,
however, or any defect therein shall not affect the legality or validity of the
resignation or removal of the Warrant Agent or the appointment of the successor
warrant agent, as the case may be.

Section 22. Issuance of New Warrant Certificates

      Notwithstanding any of the provisions of this Agreement or the several
Warrant Certificates to the contrary, the Company may, at its option, issue new
Warrant Certificates in such form as may be approved by its Board of Directors
to reflect any adjustment or change in the Exercise Price or the number or kind
of shares purchasable under the several Warrant Certificates made in accordance
with the provisions of this Agreement.

Section 23. Notices

the Warrant Agent.

Section 24. Modification of Agreement

Warrantholders, by supplemental agreement or otherwise, concur with the Company
in making any changes or corrections in this Agreement that the Warrant Agent
shall have been advised by counsel (who may be counsel for the Company) are
necessary or desirable to cure any ambiguity or to correct any defective or

deemed to be a contract made under the laws of the State of Oregon and for all
purposes shall be construed in accordance with the laws of said State.

Section 27. Termination

Expiration Date, or such earlier date upon which all Warrants shall have been

Company as to all Warrants outstanding and all cash held by it as of the close
of business on the Expiration Date.

Section 28. Benefits of this Agreement

construed to give to any person or corporation other than the Company, the
Warrant Agent, and their respective successors and assigns hereunder and the
registered holders of the Warrant Certificates any legal or equitable right,
remedy or claim under this Agreement; but this Agreement shall be for the sole

Certificates.

THIS CERTIFIES THAT


or registered assigns, is the registered holder of the number of Warrants
("Warrants") set forth above. Each Warrant entitles the holder thereof to
purchase from microHelix, Inc., a corporation incorporated under the laws of the
State of Oregon ("Company"), subject to the terms and conditions set forth
hereinafter and in the Warrant Agreement hereinafter more fully described (the
"Warrant Agreement") referred to, at any time on or before the close of business
on __________ __, 2006 or, if such Warrant is redeemed as provided in the
Warrant Agreement, at any time prior to the effective time of such redemption
(the "Expiration Date"), one fully paid and non-assessable share of Common Stock
Stock of the Company ("Common Stock") upon presentation and surrender of this
Warrant Certificate, with the instructions for the registration and delivery of
Common Stock filled in, at the stock transfer office in __________, Oregon, of
__________________, Warrant Agent of the Company ("Warrant Agent") or of its
successor warrant agent or, if there be no successor warrant agent, at the
corporate offices of the Company, and upon payment of the Exercise Price (as
defined in the Warrant Agreement) and any applicable taxes paid either in cash,
or by certified or official bank check, payable in lawful money of the United
States of America to the order of the Company. Each Warrant initially entitles
the holder to purchase one share of Common Stock for $______ at any time on or
before ________ _, 2006. The number and kind of securities or other property for
which the Warrants are exercisable are subject to further adjustment in certain
events, such as mergers, splits, stock dividends, recapitalizations and the
like, to prevent dilution. The Company may redeem any or all outstanding and
unexercised Warrants at any time after the Company has reported earnings of not
less than $0.60 per share (adjusted as described above) for any fiscal year,
upon 30 days notice, at a price equal to $0.25 per Warrant. All Warrants not
theretofore exercised or redeemed will expire on __________ _, 2006.

      This Warrant Certificate is subject to all of the terms, provisions and
conditions of the Warrant Agreement, dated as of __________ __, 2001 ("Warrant
Agreement"), between the Company and the Warrant Agent, to all of which terms,
provisions and conditions the registered holder of this Warrant Certificate
consents by acceptance hereof. The Warrant Agreement is incorporated herein by
reference and made a part hereof and reference is made to the Warrant Agreement
for a full description of the rights, limitations of rights, obligations, duties
and immunities of the Warrant Agent, the Company and the holders of the Warrant
Certificates. Copies of the Warrant Agreement are available for inspection at
the stock transfer office of the Warrant Agent or may be obtained upon written
request addressed to the Company at 16125 SW 72nd Avenue, Portland, Oregon
97224, Attention: Chief Financial Officer.

      The Company shall not be required upon the exercise of the Warrants
evidenced by this Warrant Certificate to issue fractions of Warrants, Common
Stock or other securities, but shall make adjustment therefor in cash on the
basis of the current market value of any fractional interest as provided in the
Warrant Agreement.



                                       i
<PAGE>   17

      In certain cases, the sale of securities by the Company upon exercise of
Warrants would violate the securities laws of the United States, certain states
thereof or other jurisdictions. The Company has agreed to use all commercially
reasonable efforts to cause a registration statement to continue to be effective
during the term of the Warrants with respect to such sales under the Securities
Act of 1933, and to take such action under the laws of various states as may be
required to cause the sale of securities upon exercise to be lawful. However,
the Company will not be required to honor the exercise of Warrants if, in the
opinion of the Board of Directors, upon advice of counsel, the sale of
securities upon such exercise would be unlawful. In certain cases, the Company
may, but is not required to, purchase Warrants submitted for exercise for a cash
price equal to the difference between the market price of the securities
obtainable upon such exercise and the exercise price of such Warrants.

      This Warrant Certificate, with or without other Certificates, upon
surrender to the Warrant Agent, any successor warrant agent or, in the absence
of any successor warrant agent, at the corporate offices of the Company, may be
exchanged for another Warrant Certificate or Certificates evidencing in the
aggregate the same number of Warrants as the Warrant Certificate or Certificates
so surrendered. If the Warrants evidenced by this Warrant Certificate shall be
exercised in part, the holder hereof shall be entitled to receive upon surrender
hereof another Warrant Certificate or Certificates evidencing the number of
Warrants not so exercised.

      No holder of this Warrant Certificate, as such, shall be entitled to vote,
receive dividends or be deemed the holder of Common Stock or any other
securities of the Company which may at any time be issuable on the exercise
hereof for any purpose whatever, nor shall anything contained in the Warrant
Agreement or herein be construed to confer upon the holder of this Warrant
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof or give or withhold consent to any corporate
action (whether upon any matter submitted to stockholders at any meeting
thereof, or give or withhold consent to any merger, recapitalization, issuance
of stock, reclassification of stock, change of par value or change of stock to
no par value, consolidation, conveyance or otherwise) or to receive notice of
meetings or other actions affecting stockholders (except as provided in the
Warrant Agreement) or to receive dividends or subscription rights or otherwise
until the Warrants evidenced by this Warrant Certificate shall have been
exercised and the Common Stock purchasable upon the exercise thereof shall have
become deliverable as provided in the Warrant Agreement.

      If this Warrant Certificate shall be surrendered for exercise within any
period during which the transfer books for the Company's Common Stock or other
class of stock purchasable upon the exercise of the Warrants evidenced by this
Warrant Certificate are closed for any purpose, the Company shall not be
required to make delivery of certificates for shares purchasable upon such
transfer until the date of the reopening of said transfer books.

      Every holder of this Warrant Certificate by accepting the same consents
and agrees with the Company, the Warrant Agent, and with every other holder of a
Warrant Certificate that:

  (a) this Warrant Certificate is transferable on the registry books of the
Warrant Agent only upon the terms and conditions set forth in the Warrant
Agreement, and

  (b) the Company and the Warrant Agent may deem and treat the person in whose
name this Warrant Certificate is registered as the absolute owner hereof
(notwithstanding any notation of ownership or other writing thereon made by
anyone other than the Company or the Warrant Agent) for all purposes whatever
and neither the Company nor the Warrant Agent shall be affected by any notice to
the contrary.

      The Company shall not be required to issue or deliver any certificate for
shares of Common Stock or other securities upon the exercise of Warrants
evidenced by this Warrant Certificate until any tax which may be payable in
respect thereof by the holder of this Warrant Certificate pursuant to the
Warrant Agreement shall have been paid, such tax being payable by the holder of
this Warrant Certificate at the time of surrender.
