hereinafter referred to as the “Company”, has granted to the individual (the “Participant”) named
in the Notice of Grant of Restricted Stock Units (the “Notice”) to which this Restricted Stock Unit
Agreement (the “Agreement”) relates, an award (the “Award”) of Restricted Stock Units upon the
terms and conditions set forth in the Notice and this Agreement. The Award has been granted
pursuant to and shall in all respects be subject to the terms and conditions of the Cohu, Inc. 2005
Equity Incentive Plan (the “Plan”), as amended to the Date of Grant. By signing the Notice, the
Participant: (a) represents that the Participant has read and is familiar with the terms and
conditions of the Notice, the Plan and this Agreement, (b) accepts the Award subject to all of the
terms and conditions of the Notice, the Plan and this Agreement, (c) agrees to accept as binding,
conclusive and final all decisions or interpretations of the Board of Directors of the Company,
hereinafter referred to as the “Board”, upon any questions arising under the Notice, the Plan or
this Agreement, and (d) acknowledges receipt of a copy of the Notice, the Plan and this Agreement
in either paper form or through electronic means.

1. Definitions and Construction.

1.1 Definitions. Unless otherwise defined herein, capitalized terms shall have the meanings
assigned to such terms in the Notice or the Plan.

1.2 Construction. Captions and titles contained herein are for convenience only and shall not
affect the meaning or interpretation of any provision of this Agreement. Except when otherwise
indicated by the context, the singular shall include the plural and the plural shall include the
singular. Use of the term “or” is not intended to be exclusive, unless the context clearly
requires otherwise.

2. Administration.

All questions of interpretation concerning this Agreement shall be determined by the Board.
All determinations by the Board shall be final and binding upon all persons having an interest in
the Award. Any officer of the Company shall have the authority to act on behalf of the Company
with respect to any matter, right, obligation, or election which is the responsibility of or which
is allocated to the Company herein, provided the officer has apparent authority with respect to
such matter, right, obligation, or election.

3. Settlement of the Award.

3.1 No Additional Payment Required. The Participant shall not be required to make any
additional monetary payment (other than applicable tax withholding, if any) upon settlement of the
Award. Payment of the aggregate purchase price of the shares of Stock for which the Award is being
settled shall be made in the form of past services rendered by the Participant to the Company or
for its benefit which the Board, by resolution, determines to have a value not less than the
aggregate purchase price of such shares of Stock.

3.2 Issuance of Shares of Stock. Subject to the provisions of Section 3.5 below,
the Company shall issue to the Participant, on a date (the “Settlement Date”) within thirty (30)
days following the earlier of (a) the Settlement Date (as defined in the Notice) or (b) the date of
termination of the Participant’s Service, a number of whole shares of Stock equal to the vested
Number of Restricted Stock Units (as defined in the Notice), rounded down to the nearest whole
number. Such shares of Stock shall not be subject to any restriction on transfer other than any
such restriction as may be required pursuant to Section 3.5. On the Settlement Date, the Company
shall pay to the Participant cash in lieu of any fractional share of Stock represented by a
fractional Restricted Stock Unit subject to this Award in an amount equal to the Fair Market Value
on the Settlement Date of such fractional share of Stock.

 3.3 Tax Withholding. To meet the obligations of the
Company with respect to any and all income tax, (including federal, state and local taxes), social
insurance contributions, payroll tax, payment on account or other tax-related withholding
(“Tax-Related Items”) under any applicable domestic or foreign, federal, state or local statute,
ordinance, rule, or regulation in connection with any aspect of the Restricted Stock Units,
including the grant of the Restricted Stock Units, the vesting of the Restricted Stock Units, the
conversion of the Restricted Stock Units into shares or the receipt of an equivalent cash payment,
the subsequent sale of any shares acquired at vesting and the receipt of any dividends, the
Committee shall require that the Company withhold a number of whole shares of Company Stock
otherwise deliverable having a Fair Market Value sufficient to satisfy the statutory minimum (or
such higher amount as is allowable without adverse accounting consequences) of the Participant’s
estimated total obligation for Tax-Related Items associated with any aspect of the Restricted Stock
Units. The Company may also in lieu of or in addition to the foregoing, at its sole discretion,
(i) require the Participant to deposit with the Company an amount of cash sufficient to meet his or
her obligation for Tax-Related Items , (ii) withhold the required amounts from the Participant’s
pay during the pay periods next following the date on which any such applicable tax liability
otherwise arises, and/or (iii) sell or arrange for the sale of shares to be issued on the vesting
of the Restricted Stock Units to satisfy the Participant’s and the Company’s obligation for
Tax-Related Items. If the Participant’s and/or the Company’s obligation for Tax-Related Items is
satisfied as described in (iii) of this section, the Company will endeavor to sell only the number
of shares required to satisfy the Participant’s and the Company’s obligation for Tax-Related Items;
however, the Participant agrees that the Company may sell more shares than necessary to cover the
Tax-Related Items. The Company shall not deliver any of the shares of Company Stock until and
unless the Participant has made the deposit required herein or proper provision for required
withholding has been made. The Participant hereby consents to any action reasonably taken by the
Company to meet his or her obligation for Tax-Related Items

3.4 Certificate Registration. The certificate for the shares as to which the Award
is settled shall be registered in the name of the Participant, or, if applicable, in the names of
the heirs of the Participant.

3.5 Restrictions on Grant of the Award and Issuance of Shares. The grant of the Award and
issuance of shares of Stock upon settlement of the Award shall be subject to compliance with all
applicable requirements of federal, state or foreign law with respect to such securities. No
shares of Stock may be issued hereunder if the issuance of such shares would constitute a violation
of any applicable federal, state or foreign securities laws or other law or regulations or the
requirements of any stock exchange or market system upon which the Stock may then be listed. The
inability of the Company to obtain from any regulatory body having jurisdiction the authority, if
any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any
shares subject to the Award shall relieve the Company of any liability in respect of the failure to
issue or sell such shares as to which such requisite authority shall not have been obtained. As a
condition to the settlement of the Award, the Company may require the Participant to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with any applicable law
or regulation and to make any representation or warranty with respect thereto as may be requested
by the Company.

3.6 Fractional Shares. The Company shall not be required to issue fractional shares upon the
settlement of the Award.

3.7 Deferral. Subject to the Committee’s determination that this right of deferral or any
term thereof complies with applicable laws or regulations in effect from time to time, Participant
may make an election to defer the issuance of the shares issuable in accordance with the terms and
conditions set forth in a Restricted Stock Unit deferral election form approved by the Committee.
In the event of the Committee’s determination otherwise, the Committee may, in its discretion, deny
Participant this right of deferral altogether, modify the terms of the deferral and/or add such
requirements as it deems necessary or advisable to comply with applicable law and regulations. If
the Participant elects to defer the issuance of vested Restricted Stock Units in accordance with
this paragraph, payment of the deferred vested Restricted Stock Units (and any dividends payable in
accordance with paragraph 9) will be made in accordance with the terms of the deferral election.

3.8 Dividend Equivalents for Deferred Restricted Stock Units. If the Participant elects
to defer the issuance of vested Restricted Stock Units (the “Deferred Restricted Stock Units”) in
accordance with Section 3.7, the Participant will be entitled to receive dividends or distributions
paid on the shares of Stock underlying vested Deferred Restricted Stock Units in accordance with
this Section 3.8. Any such dividends or distributions automatically will be credited as Deferred
Restricted Stock Unit (the “Dividend Restricted Stock Units”).

a. Cash Dividends. If the Company declares and pays any cash dividends or cash distributions
on the share of Stock during a calendar year, then with respect to the Deferred Restricted Stock
Units that have vested as of the date the cash dividend or distribution was paid and that remain
unissued on the last Nasdaq Global Select Market trading day of that year (the “Applicable Date”),
such Deferred Restricted Stock Units will be increased on the Applicable Date by a number of
Dividend Restricted Stock Units equal to the quotient obtained by dividing the cash dividend or
distribution paid on the shares of Stock underlying such vested Deferred Restricted Stock Units by
the Fair Market Value (as defined in the Plan) of a share of Stock on the Applicable Date, rounded
down to the nearest whole share. Specifically, the number of Dividend Restricted Stock Units for
each cash dividend or distribution during a calendar year will be determined in accordance with the
following formula, rounded down to the nearest whole Share of Stock: X = (A x B)/C, where X = the
Dividend Restricted Stock Units that will become vested Deferred Restricted Stock Units on the
Applicable Date by reason of the cash dividend or distribution paid during the year, A = the number
of unissued shares of stock that were vested as of the cash dividend or distribution date and
remain subject to the vested Deferred Restricted Stock Units as of the Applicable Date, B = the per
share of Stock amount of the applicable cash dividend or distribution, and C = the Fair Market
Value of a share of Stock on the Applicable Date.

b. Stock Dividends. If the Company declares and pays any stock dividends or stock distribution
on shares of Stock during a calendar year, then the number of unissued shares of Stock, if any,
that remain subject to Participant’s vested Deferred Restricted Stock Units automatically will be
adjusted in accordance with Section 7.

c. Any Dividend Restricted Stock Units resulting from the application of this Section 3.8 will
be subject to the same terms and conditions (including, without limitation, the applicable deferral
election and forfeiture provisions) as the unissued Deferred Restricted Stock Units to which they
relate.

4. Nontransferability of the Award.

Prior to the Settlement Date, neither this Award nor any Restricted Stock Unit subject to this
Award shall be subject in any manner to anticipation, alienation, sale, transfer, assignment,
pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s
beneficiary, except by will or by the laws of descent and distribution.

5. Effect of Termination of Service.

If the Participant’s Service (as defined below) is terminated by the Participant or by the
Company for any reason, including Participant’s death or disability before all Restricted Stock
Units have vested, the unvested Restricted Stock Units shall be forfeited by the Participant. As of
the 31st (or 91st if reemployment is guaranteed by statute or contract) day of a leave of absence,
vesting of the Restricted Stock Units will be suspended and vesting credit will no longer accrue,
unless otherwise determined by the Committee or required by contract or statute. If the Participant
returns to Service immediately after the end of an approved leave of absence, vesting credit shall
continue to accrue from that date of continued Service. For purposes of this Agreement, “Service”
shall mean the performance of services for the Company in the capacity of an Employee, Officer,
Consultant, or Director.

6. Change in Control. 

In the event of a Change in Control, the surviving, continuing, successor, or purchasing
corporation or other business entity or parent thereof, as the case may be (the “Acquiror”), may,
without the consent of the Participant, either assume the Company’s rights and obligations under
the Award or substitute for the Award a substantially equivalent award with respect to the
Acquiror’s stock. If the Award is neither assumed or substituted for by the Acquiror in connection
with the Change in Control, then the Award shall become 100% vested and settled in accordance with
Section 3 immediately prior to the effective date of the Change in Control. Furthermore,
notwithstanding the foregoing, if the corporation the stock of which is subject to the Award
immediately prior to an Ownership Change Event described in Section 13.1(a)(i) of the Plan
constituting a Change in Control is the surviving or continuing corporation and immediately after
such Ownership Change Event less than fifty percent (50%) of the total combined voting power of its
voting stock is held by another corporation or by other corporations that are members of an
affiliated group within the meaning of Section 1504(a) of the Code without regard to the provisions
of Section 1504(b) of the Code, the Award shall not terminate unless the Board otherwise provides
in its discretion.

7. Adjustments for Changes in Capital Structure.

Subject to any required action by the stockholders of the Company, in the event of any change
in the Stock effected without receipt of consideration by the Company, whether through merger,
consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend,
stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of
shares, or similar change in the capital structure of the Company, or in the event of payment of a
dividend or distribution to the stockholders of the Company in a form other than Stock (excepting
normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock,
appropriate and proportionate adjustments shall be made in the number and class of shares subject
to the Award, in order to prevent dilution or enlargement of the Participant’s rights under the
Award. For purposes of the foregoing, conversion of any convertible securities of the Company
shall not be treated as “effected without receipt of consideration by the Company.” Any fractional
share resulting from an adjustment pursuant to this Section 7 shall be rounded down to the nearest
whole number. Such adjustments shall be determined by the Board, and its determination shall be
final, binding and conclusive.

8. Rights as a Stockholder, Director, Employee or Consultant.

The Participant shall have no rights as a stockholder with respect to any shares which may be
issued in settlement of this Award until the date of the issuance of a certificate for such shares
(as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company). Except as provided in Section 3.8, no adjustment shall be made for
dividends, distributions or other rights for which the record date is prior to the date such
certificate is issued. If the Participant is an Employee, the Participant understands and
acknowledges that, except as otherwise provided in a separate, written employment agreement between
the Company and the Participant, the Participant’s employment is “at will” and is for no specified
term. Nothing in this Agreement shall confer upon the Participant any right to continue in the
Service of the Company or interfere in any way with any right of the Company to terminate the
Participant’s Service as a Director, an Employee or a Consultant, as the case may be, at any time.

9. Legends.

The Company may at any time place legends referencing any applicable federal, state or foreign
securities law restrictions on all certificates representing shares of stock issued pursuant to
this Agreement. The Participant shall, at the request of the Company, promptly present to the
Company any and all certificates representing shares acquired pursuant to this Award in the
possession of the Participant in order to carry out the provisions of this Section.

10. Miscellaneous Provisions.

10.1 Further Instruments. The parties hereto agree to execute such further instruments and to
take such further action as may reasonably be necessary to carry out the intent of this Agreement.

10.2 Binding Effect. Subject to the restrictions on transfer set forth herein, this Agreement
shall inure to the benefit of and be binding upon the parties hereto and their respective heirs,
executors, administrators, successors and assigns.

10.3 Termination or Amendment. The Board may terminate or amend the Plan or the Award at any
time; provided, however, that except as provided in Section 6 in connection with a Change in
Control, no such termination or amendment may adversely affect the Award without the consent of the
Participant unless such termination or amendment is necessary to comply with any applicable law or
government regulation. No amendment or addition to this Agreement shall be effective unless in
writing.

10.4 Notices. Any notice required or permitted hereunder shall be given in writing and shall
be deemed effectively given (except to the extent that this Agreement provides for effectiveness
only upon actual receipt of such notice) upon personal delivery, upon deposit in the United States
Post Office, by registered or certified mail, or with an overnight courier service with postage and
fees prepaid, addressed to the other party at the address shown below that party’s signature or at
such other address as such party may designate in writing from time to time to the other party.

10.5 Integrated Agreement. The Notice and this Agreement constitute the entire understanding
and agreement of the Participant and the Company with respect to the subject matter contained
herein or therein and supersede any prior agreements, understandings, restrictions,
representations, or warranties among the Participant and the Company with respect to such subject
matter other than those as set forth or provided for herein or therein. To the extent contemplated
herein or therein, the provisions of the Notice and the Agreement shall survive any settlement of
the Award and shall remain in full force and effect.

10.6 Applicable Law. This Agreement shall be governed by the laws of the State of California
as such laws are applied to agreements between California residents entered into and to be
performed entirely within the State of California.

10.7 Counterparts. The Notice may be executed in counterparts, each of which shall be deemed
an original, but all of which together shall constitute one and the same instrument.

10.8 Electronic Delivery. The Company may, in its sole discretion, decide to deliver any
documents related to the Restricted Stock Units granted under the Plan and participation in the
Plan or future Restricted Stock Units that may be granted under the Plan by electronic means or to
request the Participant’s consent to participate in the Plan by electronic means. The Participant
hereby consents to receive such documents by electronic delivery and, if requested, to agree to
participate in the Plan through an on-line or electronic system established and maintained by the
Company or another third party designated by the Company.

	FROM:

I hereby elect to defer the settlement date of my Restricted Stock Units that I would

Company’s 2005 Equity Incentive Plan (the “Plan”) and this election. I understand that my election
is irrevocable. The terms of my election are as follows:

1. Plan Year to which Election applies. My election applies to the following Plan Year (the
“Election Period”):

[      ] Initial Plan Year:      , 2006 through December 31, 2006.

This election will terminate at the end of each Plan Year (unless voluntarily extended by me
prior to the beginning of a new Plan Year) or effective as of the day on which I either terminate
Service or the Plan terminates. This election and any future elections may also be terminated,
amended, or otherwise revised, at the Company’s discretion should it determine that the Restricted
Stock Unit program should be so terminated, amended or otherwise revised.

2. Restricted Stock Units Deferred. I elect to defer settlement of the following portion of
my Restricted Stock Units Award made to me during the Election Period (must be at a minimum of at
least 10% and may increase in 5% increments thereafter):

     %

3. Restricted Stock Units Deferral Elections. I hereby make the following elections with
respect to the settlement of my vested Restricted Stock Units that will be payable in a single lump
sum as provided in my Restricted Stock Unit Agreement (“Agreement”). I understand that if I fail to
make an election, or if the election is terminated, that I will be deemed to have elected
settlement of my Restricted Stock Units when such units vest as provided in the Restricted Stock
Units Notice of Grant.

Settlement Date:

Subject to the terms of the Plan and my Agreement, I will receive shares of Stock in
settlement of my Award (to the extent vested) within 30 days of the earlier of (i) any
Settlement Date I have elected below, (ii) the date of my termination of Service or (iii) the
date of any Change of Control, as defined in the Plan, if such an Award is not assumed or
substituted for a similar award.

I understand that:

A Settlement Date may be no earlier than January 1 of the second calendar year following the
Election Period (e.g. if the Election Period ends on December 31, 2006, the Settlement Date
may be no earlier than January 1, 2008).

That I may (but am not required) to elect a Settlement Date, however, if I don’t select a
Settlement Date, but have completed this form and elected to defer settlement of the Award
beyond the date such award would have become vested, that I will have made an irrevocable
election to defer settlement of the Award until my termination of Service.

I elect a Settlement Date for 100% of my Award on      . (please select a date no
earlier than January 1 of the second calendar year following the Election Period, however,
remember that the Award becomes vested on the date provided in the Notice of Grant and unless
you select a later Settlement Date, would be settled on the vesting date)

	 	 	 	 	 	 	 
	 
	 	 
	 	 
	 	[      ] I do not elect a Settlement Date (and I understand

this means that the Settlement Date will be the date I

terminated Service).

Change of Settlement Date:

I understand that I may make, with the consent of the Company, a subsequent election to
further defer settlement of this Award, and that such an election must be made at least one
(1) year prior to my originally selected Settlement Date and I further understand that my
newly elected Settlement Date must be at least five (5) years after the date of the originally
selected Settlement Date. I further understand that the ability to make such a subsequent
deferral election may not be available to me in the future if the Company changes its
administration policies to reflect any changes to the applicable law governing deferred
compensation.

4. Filing of Election. This Restricted Stock Unit Election must be filed with the Chief
Financial Officer of the Company no later than:

	 	For elections to defer receipt of Restricted Stock Units

during each subsequent Plan Year: the day prior to the

first day of such Plan Year.

5. Irrevocability of Election. This Restricted Stock Unit Election will become
irrevocable as of the commencement of the Election Period.

6. Award is Unfunded. I understand that the Company has not formally funded my Award and
that I am considered a general unsecured creditor of the Company with respect to my rights under
the Award.

7. Subject to Plan. This Restricted Stock Unit Election is in all respects subject to the
terms and conditions of the Plan. Should any inconsistency exist between this Restricted Stock Unit
Election, the Plan, the Restricted Stock Unit Agreement, and/or any applicable law, then the
provisions of either the applicable law or the Plan will control, with the Plan subordinated to the
applicable law.

(q) “Loan Agreement” has the meaning in the second introductory paragraph of this Note.

(r) “Successor Entity” has the meaning given in Section 10 hereof.

Capitalized term not otherwise defined shall have the meaning set forth in the Loan Agreement.

2. Interest. Unless converted into Common Stock of Company as set forth in Section 8
below, or unless prepaid or converted as set forth in Section 3 below, accrued interest on this
Note shall be payable on the Maturity Date.

3. Prepayment. During the Conversion Period, Company may, at any time and from time
to time, prepay all or any portion of the principal due under this Note, together with accrued
interest, without penalty. Company shall effect such prepayment by providing Holder twenty (20)
days written notice prior to the date of such prepayment (such notice, a “Prepayment Notice”)
indicating the amount of principal and accrued interest Company desires to prepay (the “Prepayment
Amount”). Notwithstanding the foregoing, Holder shall have 10 days following receipt of such
Prepayment Notice to notify Company in writing of its election to convert the Prepayment Amount
into shares of Common Stock, in which case such Prepayment Amount shall be converted into shares of
Common Stock in accordance with the conversion procedures set forth in Section 8(e) hereof
(provided that, with respect to conversions effected pursuant to this Section 3, any references to
the Conversion Amount in Section 8(e) shall refer to the Prepayment Amount). Should Holder elect
to convert the Prepayment Amount into shares of Common Stock, the number of shares of Common Stock
into which such Prepayment Amount will be converted shall be determined by dividing the Prepayment
Amount by the then applicable Conversion Price.

4. Security Interest. As security for the payment and performance of the Obligations
under this Note and the other Notes, Company hereby grants to the holder of this Note and of the
other Notes a first lien security interest in all of Company’s right, title and interest in, to and
under all of its personal property, wherever located and whether now existing or owned or hereafter
acquired or arising, including all accounts, chattel paper, commercial tort claims, deposit
accounts, documents, equipment (including all fixtures), general intangibles, intellectual property
(including all patents and patent applications, all copyrights and applications for copyright, all
state (including common law), federal and foreign trademarks, service marks and trade names, and
applications for registration of such trademarks, service marks and trade names, and all trade
secrets), instruments, inventory, investment property, letter-of-credit rights, money and all
products, proceeds and supporting obligations of any and all of the foregoing (collectively, the
“Collateral”). Notwithstanding the foregoing, the security interest granted herein shall not
extend to any property, rights or licenses to the extent the granting of a security interest
therein would be contrary to applicable law.

5. Representations and Warranties of Holder. Holder represents and warrants to Company
as follows:

(a) Binding Obligation. Holder has full legal capacity, power and authority to execute
and deliver this Note and to perform his obligations hereunder. This Note is a valid and binding
obligation of Holder, enforceable in accordance with its terms, except as limited by bankruptcy,
insolvency or other laws of general application relating to or affecting the enforcement of
creditors’ rights generally and general principles of equity.

(b) Securities Law Compliance. Holder has been advised that this Note has not been
registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state
securities laws and, therefore, cannot be resold unless they are registered under the Securities
Act and applicable state securities laws or unless an exemption from such registration requirements
is available. Holder is aware that Company is under no obligation to effect any such registration
with respect to this Note, or the Common Stock issuable or issued pursuant to the conversion of
this Note, or to file for or comply with any exemption from registration. Holder has not been
formed solely for the purpose of making this investment and is purchasing this Note for its own
account for investment, not as a nominee or agent, and not with a view to, or for resale in
connection with, the distribution thereof. Holder has such knowledge and experience in financial
and business matters that Holder is capable of evaluating the merits and risks of such investment,
is able to incur a complete loss of such investment and is able to bear the economic risk of such
investment for an indefinite period of time.

(c) Accredited Investor. Holder is an “accredited investor” within the meaning of SEC
Rule 501 of Regulation D of the Securities Act, as presently in effect.

(d) Restricted Securities. Holder understands that this Note is a “restricted
security” under the federal securities laws inasmuch as it is being acquired from Company in a
transaction not involving a public offering and that under such laws and applicable regulations
such Note may be resold without registration under the Securities Act only in certain limited
circumstances. In the absence of an effective registration statement covering the Note or an
available exemption from registration under the Securities Act, the Note must be held indefinitely.
Holder represents that it is familiar with SEC Rule 144, and understands the resale limitations
imposed thereby and by the Securities Act.

(e) Access to Information. Holder acknowledges that Company has given Holder access
to the corporate records and accounts of Company and to all information in its possession relating
to Company, has made its officers and representatives available for interview by Holder, and has
furnished Holder with all documents and other information required for Holder to make an informed
decision with respect to the purchase of this Note.

6. Events of Default. The occurrence of any of the following shall constitute an
“Event of Default” under this Note:

(a) Failure to Pay. Company shall fail to pay (i) when due any principal or interest
payment on the due date hereunder or (ii) any other payment required under the terms of this Note
on the date due, and (in either case) such payment shall not have been made within twenty (20) days
of Company’s receipt of Holder’s written notice to Company of such failure to pay;

(b) Failure to Perform. Company fails to perform any obligation under this Note and
does not cure that failure within twenty (20) days of Company’s receipt of Holder’s written notice
to Company of such failure to perform; or

(c) Voluntary Bankruptcy or Insolvency Proceedings. Company shall (i) apply for or
consent to the appointment of a receiver, trustee, liquidator or custodian of itself or of all or a
substantial part of its property, (ii) be unable, or admit in writing its inability, to pay its
debts generally as they mature, (iii) make a general assignment for the benefit of its or any of
its creditors, (iv) be dissolved or liquidated, (v) become insolvent (as such term may be defined
or interpreted under any applicable statute), (vi) commence a voluntary case or other proceeding
seeking liquidation, reorganization or other relief with respect to itself or its debts under any
bankruptcy, insolvency or other similar law now or hereafter in effect or consent to any such
relief or to the appointment of or taking possession of its property by any official in an
involuntary case or other proceeding commenced against it, or (vii) take any action for the purpose
of effecting any of the foregoing; or

(d) Involuntary Bankruptcy or Insolvency Proceedings. Proceedings for the appointment
of a receiver, trustee, liquidator or custodian of Company or of all or a substantial part of the
property thereof, or an involuntary case or other proceedings seeking liquidation, reorganization
or other relief with respect to Company or the debts thereof under any bankruptcy, insolvency or
other similar law now or hereafter in effect shall be commenced and an order for relief entered or
such proceeding shall not be dismissed or discharged within thirty (30) days of commencement.

7. Rights of Holder upon Default. Upon the occurrence or existence of any Event of
Default (other than an Event of Default referred to in Sections 6(c) and 6(d)) and at any time
thereafter during the continuance of such Event of Default, the Majority Holders may, by written
notice to Company, declare all outstanding Obligations payable by Company under the Notes to be
immediately due and payable without presentment, demand, protest or any other notice of any kind,
all of which are hereby expressly waived. Upon the occurrence or existence of any Event of Default
described in Sections 6(c) and 6(d), immediately and without notice, all outstanding Obligations
payable by Company under the Notes shall automatically become immediately due and payable, without
presentment, demand, protest or any other notice of any kind, all of which are hereby expressly
waived. In addition to the foregoing remedies, upon the occurrence or existence of any Event of
Default, Holder may exercise any other right power or remedy permitted to him by law, either by
suit in equity or by action at law, or both.

8. Conversion.

(a) Conversion. Holder shall have the right to convert, at any time during the
Conversion Period, all or any portion of the principal amount, together with any unpaid and accrued
interest, then outstanding under this Note into fully paid and non-assessable shares of Common
Stock at a conversion price per share equal to the Conversion Price (as defined below). The number
of shares of Common Stock into which such principal and interest then outstanding under this Note
will be converted shall be determined by dividing the amount of principal, together with all unpaid
and accrued interest, then outstanding under this Note to be converted (the “Conversion Amount”) by
the Conversion Price.

(b) Conversion Price. Subject to Section 8(c), the “Conversion Price” shall be equal
to 80% of the Average Trading Price as reported by the principal trading exchange on which the
Company’s Common Stock is traded for the twenty (20) trading days preceding the date of the Note.

(c) Adjustments to Conversion Price. The Conversion Price shall be subject to
proportional adjustments for stock splits, stock dividends, combinations, consolidations,
reclassifications and the like.

(d) Conversion Procedure. Before Holder shall be entitled to convert the Conversion
Amount then outstanding under this Note into shares of Common Stock, Holder shall surrender this
Note at the office of this Company, and shall give written notice (a form of which is attached to
this Note, the “Conversion Notice”) to Company at its principal corporate office, of the election
to convert the same and shall state therein the total Conversion Amount. Company shall not be
obligated to issue certificates evidencing the shares of Common Stock issuable upon such conversion
unless (i) Holder executes and delivers to Company the Conversion Notice for the converted shares
and (ii) this Note is delivered to Company. Company shall, as soon as practicable after such
delivery, issue and deliver certificates (bearing such legends as are required by applicable state
and federal securities laws in the opinion of counsel to Company and required by this Note and the
Loan Agreement), representing the number of fully paid and non-assessable shares of the Common
Stock into which the Conversion Amount will be converted in accordance with the provisions herein,
and a new promissory note having like tenor as this Note for the principal amount and interest then
outstanding under this Note that are not being so converted. Any conversion pursuant to this
Section 8 shall be deemed to have been made immediately prior to the close of business on the date
of Company’s receipt of the Conversion Notice, so that the rights of Holder under this Note to the
extent of the Conversion Amount shall cease at such time and Holder shall be treated for all
purposes as having become the record holder of such shares of Common Stock at such time.

(e) Fractional Shares; Effect of Conversion. No fractional shares shall be issued
upon conversion of this Note. In lieu of Company issuing any fractional shares to Holder upon the
conversion of this Note, Company shall pay to Holder an amount equal to the product obtained by
multiplying the Conversion Price by the fraction of a share not issued pursuant to the previous
sentence. Upon conversion of this Note in full and the payment of the amounts specified in this
Section 9(f), Company shall be forever released from all its obligations and liabilities under this
Note.

(f) Reservation of Stock Issuable Upon Conversion. Company shall at all times reserve
and keep available out of its authorized but unissued shares of Common Stock solely for the purpose
of effecting the conversion of this Note such number of its shares of Common Stock as shall from
time to time be sufficient to effect the conversion of this Note.

9. Reserved

10. Effect of Sale Transaction. Upon the occurrence of any Sale Transaction, the
Successor Entity (as defined below) shall succeed to, and be substituted for the Company (so that
from and after the date of such Sale Transaction, the provisions of this Note referring to the
“Company” shall refer instead to the Successor Entity), and may exercise every right and power of
the Company and shall assume all of the obligations of the Company under this Note with the same
effect as if such Successor Entity had been named as the Company herein. Upon consummation of the
Sale Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be
issued upon conversion of this Note at any time after the consummation of the Sale Transaction, in
lieu of the shares of the Common Stock purchasable upon the conversion of the Notes prior to such
Sale Transaction, such shares of common stock (or other securities, cash, assets or other property)
of the Successor Entity. The provisions of this Section shall apply similarly and equally to
successive Sale Transactions and shall be applied without regard to any limitations on the
conversion of this Note. As used in this Section 10, “Successor Entity” means the Person, which
may be the Company, formed by, resulting from or surviving any Sale Transaction, or the parent
entity of such Person, as applicable.

11. Successors and Assigns. Subject to the restrictions on transfer described in
Sections 12 and 13 below, the rights and obligations of Company and Holder of this Note shall be
binding upon and benefit the successors, assigns, heirs, administrators and transferees of the
parties.

12. Waiver and Amendment. Any term of this Note may be amended or waived only with
the written consent of Company and the Majority Holders; provided, however, that any such amendment
or modification which by its terms would not apply equally to all holders of the Notes shall not be
applicable to any holder whose rights under the Notes would be adversely affected by such amendment
or modification in a different manner than other holders thereof without such adversely affected
holder’s written consent.

13. Transfer of this Note or Securities Issuable on Conversion Hereof. With respect
to any offer, sale or other disposition of this Note or securities into which such Note may be
converted, Holder will give written notice to Company prior thereto, describing briefly the manner
thereof, together with a written opinion of Holder’s counsel, or other evidence if reasonably
satisfactory to Company, to the effect that such offer, sale or other distribution may be effected
without registration or qualification (under any federal or state law then in effect). Upon
receiving such written notice and reasonably satisfactory opinion, if so requested, or other
evidence, Company, as promptly as practicable, shall notify Holder that Holder may sell or
otherwise dispose of this Note or such securities, all in accordance with the terms of the notice
delivered to Company. If a determination has been made pursuant to this Section 12 that the
opinion of counsel for Holder, or other evidence, is not reasonably satisfactory to Company,
Company shall so notify Holder promptly after such determination has been made. Each Note thus
transferred and each certificate representing the securities thus transferred shall bear a legend
as to the applicable restrictions on transferability in order to ensure compliance with the
Securities Act, unless in the opinion of counsel for Company such legend is not required in order
to ensure compliance with the Securities Act. Company may issue stop transfer instructions to its
transfer agent in connection with such restrictions. Subject to the foregoing, transfers of this
Note shall be registered upon registration books maintained for such purpose by or on behalf of
Company. Prior to presentation of this Note for registration of transfer, Company shall treat the
registered Holder hereof as the owner and Holder of this Note for the purpose of receiving all
payments of principal and interest hereon and for all other purposes whatsoever, whether or not
this Note shall be overdue and Company shall not be affected by notice to the contrary.

14. Notices. Any notices, consents, waivers or other communications required or
permitted to be given under the terms of this Agreement must be in writing and will be deemed to
have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by
facsimile (provided confirmation of transmission is mechanically or electronically generated and
kept on file by the sending party); or (iii) one business day after deposit with an overnight
courier service, in each case properly addressed to the party to receive the same. The addresses
and facsimile numbers for such communications shall be to the respective addresses or facsimile
numbers of the parties as set forth in the Loan Agreement, or at such other address or facsimile
number as such parties shall have furnished in writing.

15. Usury. In the event any interest is paid on this Note which is deemed to be in
excess of the then legal maximum rate, then that portion of the interest payment representing an
amount in excess of the then legal maximum rate shall be deemed a payment of principal and applied
against the principal of this Note.

16. Waivers. Company hereby waives notice of default, presentment or demand for
payment, protest or notice of nonpayment or dishonor and all other notices or demands relative to
this instrument.

17. Governing Law and Forum. This Note and all actions arising out of or in
connection with this Note shall be governed by and construed in accordance with the laws of the
State of Colorado, United States of America, without regard to the conflicts of law provisions of
the State of Colorado, or of any other state. All disputes or controversies relating to or arising
from this Note shall be adjudicated in the state and federal courts located in the state of
Colorado. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION
WITH RESPECT TO THIS NOTE AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS
WAIVER. The Convention on Contracts for the International Sale of Goods shall not apply to this
Note.
