	 	Warrant to Purchase

Shares of Class A Common Stock

     THIS CERTIFIES THAT, for value received,
______________, or its registered
assigns (the “Holder”), is entitled, subject to the provisions and upon the terms and conditions
set forth herein, to purchase from Kior, Inc., a Delaware corporation (the “Company”), Shares (as
defined below), in the amounts, at such times and at the price per share set forth in Section 1.
The term “Warrant” as used herein shall include this Warrant and any warrants delivered in
substitution or exchange therefor as provided herein. This Warrant is issued pursuant to the terms
of __________ by and between the Company and ______________.

     The following is a statement of the rights of the Holder and the conditions to which this
Warrant is subject, and to which Holder, by acceptance of this Warrant, agrees:

     1. Number and Price of Shares; Exercise Period.

          (a)
Definition of Shares. “Shares” shall mean the Company’s Class A Common Stock.

          (b) Number of Shares. Subject to any previous exercise of the Warrant, the Holder shall have
the right to purchase up to ________ Shares, prior to (or in connection with) the expiration of
this Warrant as provided in Section 8.

          (c) Exercise Price. The exercise price per Share shall be equal to $___ per Share, subject to
adjustment pursuant hereto (the “Exercise Price”).

          (d) Exercise Period. This Warrant shall be exercisable, in whole or in part, any time after
the issuance hereof and prior to (or in connection with) the expiration of this Warrant as set
forth in Section 8.

 

 

     2. Exercise of the Warrant.

          (a) Exercise. The purchase rights represented by this Warrant may be exercised at the election
of the Holder, in whole or in part, in accordance with Section 1, by:

               (i) the tender to the Company at its principal office (or such other office or agency as the
Company may designate) of a notice of exercise in the form of Exhibit A (the “Notice of Exercise”),
duly completed and executed by or on behalf of the Holder, together with the surrender of this
Warrant; and

               (ii) the payment to the Company of an amount equal to (x) the Exercise Price multiplied by (y)
the number of Shares being purchased, by (a) wire transfer or certified, cashier’s or other check
acceptable to the Company and payable to the order of the Company; (b) surrender and cancellation
of promissory notes or other instruments representing indebtedness of the Company to the Holder; or
(c) a combination of (a) and (b).

     (b) Net Issue Exercise. In lieu of exercising this Warrant pursuant to Section 2(a)(ii), if
the fair market value of one Share is greater than the Exercise Price (at the date of calculation
as set forth below), the Holder may elect to receive a number of Shares equal to the value of this
Warrant (or of any portion of this Warrant being canceled) by surrender of this Warrant at the
principal office of the Company (or such other office or agency as the Company may designate)
together with a properly completed and executed Notice of Exercise reflecting such election, in
which event the Company shall issue to the Holder that number of Shares computed using the
following formula:

	 	 	 	 	 	 

	X

	 	 = 
	 	Y (A — B)
 
A	 

     Where:

	 	X  	=  	The number of Shares to be issued to the Holder
	 
	 	Y  	=  	The number of Shares purchasable under this Warrant or, if only a
portion of the Warrant is being exercised, the portion of the
Warrant being canceled (at the date of such calculation)
	 
	 	A 	=  	The fair market value of one Share (at the date of such calculation)
	 
	 	B 	=  	The Exercise Price (as adjusted to the date of such calculation)

     For purposes of the calculation above, the fair market value of one Share shall be determined
by the Board of Directors of the Company, acting in good faith; provided, however, that:

               (i) where a public market exists for the Company’s Shares at the time of such exercise, the
fair market value per Share shall be the average of the closing bid and asked prices of the Shares
or the closing price quoted on the national securities exchange on which the Shares are listed as
published in the Wall Street Journal, as applicable, for the ten (10) trading day period
ending five (5) trading days prior to the date of determination of fair market value; and

-2-

 

               (ii) if the Warrant is exercised in connection with the Company’s initial public offering of
Shares, the fair market value per Share shall be the per share offering price to the public of the
Company’s initial public offering.

          (c) Stock Certificates. The rights under this Warrant shall be deemed to have been exercised
and the Shares issuable upon such exercise shall be deemed to have been issued immediately prior to
the close of business on the date this Warrant is exercised in accordance with its terms, and the
person entitled to receive the Shares issuable upon such exercise shall be treated for all purposes
as the holder of record of such Shares as of the close of business on such date. As promptly as
reasonably practicable on or after such date, and in any event within thirty (30) days thereafter,
the Company shall issue and deliver to the person or persons entitled to receive the same a
certificate or certificates for that number of shares issuable upon such exercise. In the event
that the rights under this Warrant are exercised in part and have not expired, the Company shall
execute and deliver a new Warrant reflecting the number of Shares that remain subject to this
Warrant.

          (d) No Fractional Shares or Scrip. No fractional shares or scrip representing fractional
shares shall be issued upon the exercise of the rights under this Warrant. In lieu of such
fractional share to which the Holder would otherwise be entitled, the Company shall make a cash
payment equal to the Exercise Price multiplied by such fraction.

          (e) Conditional Exercise. The Holder may exercise this Warrant conditioned upon (and effective
immediately prior to) consummation of any transaction that would cause the expiration of this
Warrant pursuant to Section 8 by so indicating in the notice of exercise.

          (f) Automatic Exercise. If the Holder of this Warrant has not elected to exercise this Warrant
prior to expiration of this Warrant pursuant to Section 8, then this Warrant shall automatically
(without any act on the part of the Holder) be exercised pursuant to Section 2(b) effective
immediately prior to the expiration of the Warrant to the extent such net issue exercise would
result in the issuance of Shares, unless Holder shall earlier provide written notice to the Company
that the Holder desires that this Warrant expire unexercised. If this Warrant is automatically
exercised, the Company shall notify the Holder of the automatic exercise as soon as reasonably
practicable, and the Holder shall surrender the Warrant to the Company in accordance with the terms
hereof.

          (g) Reservation of Stock. The Company agrees during the term the rights under this Warrant are
exercisable to reserve and keep available from its authorized and unissued shares of Class A Common
Stock solely for the purpose of effecting the exercise of this Warrant such number of shares as
shall from time to time be sufficient to effect the exercise of the rights under this Warrant; and
if at any time the number of authorized but unissued shares of Class A Common Stock shall not be
sufficient for purposes of the exercise of this Warrant in accordance with its terms and the
conversion of the Shares, without limitation of such other remedies as may be available to the
Holder, the Company will use all reasonable efforts to take such corporate action as may be
necessary to increase its authorized and unissued shares of its Class A Common Stock to a number of
shares as shall be sufficient for such purposes. The Company represents and warrants that all
shares that may be issued upon the exercise of this Warrant will, when issued in accordance with
the terms hereof, be validly issued, fully paid and nonassessable.

     3. Replacement of the Warrant. Subject to the receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss,
theft or
destruction, on delivery of an indemnity agreement reasonably satisfactory in form and
substance to the Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at the expense of the Holder shall execute and deliver, in lieu of this
Warrant, a new warrant of like tenor and amount.

-3-

 

     4. Transfer of the Warrant.

          (a) Warrant Register. The Company shall maintain a register (the “Warrant Register”)
containing the name and address of the Holder or Holders. Until this Warrant is transferred on the
Warrant Register in accordance herewith, the Company may treat the Holder as shown on the Warrant
Register as the absolute owner of this Warrant for all purposes, notwithstanding any notice to the
contrary. Any Holder of this Warrant (or of any portion of this Warrant) may change its address as
shown on the Warrant Register by written notice to the Company requesting a change.

          (b) Warrant Agent. The Company may appoint an agent for the purpose of maintaining the Warrant
Register referred to in Section 4(a), issuing the Shares or other securities then issuable upon the
exercise of the rights under this Warrant, exchanging this Warrant, replacing this Warrant or
conducting related activities.

          (c) Transferability of the Warrant. Subject to the provisions of this Warrant with respect to
compliance with the Securities Act of 1933, as amended (the “Securities Act”) and limitations on
assignments and transfers, including without limitation compliance with the restrictions on
transfer set forth in Section 5, title to this Warrant may be transferred by endorsement (by the
transferor and the transferee executing the assignment form attached as Exhibit B (the “Assignment
Form”)) and delivery in the same manner as a negotiable instrument transferable by endorsement and
delivery.

          (d) Exchange of the Warrant upon a Transfer. On surrender of this Warrant (and a properly
endorsed Assignment Form) for exchange, subject to the provisions of this Warrant with respect to
compliance with the Securities Act and limitations on assignments and transfers, the Company shall
issue to or on the order of the Holder a new warrant or warrants of like tenor, in the name of the
Holder or as the Holder (on payment by the Holder of any applicable transfer taxes) may direct, for
the number of shares issuable upon exercise hereof, and the Company shall register any such
transfer upon the Warrant Register. This Warrant (and the securities issuable upon exercise of the
rights under this Warrant) must be surrendered to the Company or its warrant or transfer agent, as
applicable, as a condition precedent to the sale, pledge, hypothecation or other transfer of any
interest in any of the securities represented hereby.

          (e) Taxes. In no event shall the Company be required to pay any tax which may be payable in
respect of any transfer involved in the issue and delivery of any certificate in a name other than
that of the Holder, and the Company shall not be required to issue or deliver any such certificate
unless and until the person or persons requesting the issue thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the Company that such tax
has been paid or is not payable.

     5. Restrictions on Transfer of the Warrant and Shares; Compliance with Securities Laws. By
acceptance of this Warrant, the Holder agrees to comply with the following:

          (a) Restrictions on Transfers. Any transfer of this Warrant or the Shares (the “Securities”)
must be in compliance with all applicable federal and state securities laws. The Holder agrees not
to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the
Securities, or any beneficial interest therein, unless and until the transferee thereof has agreed
in writing for the benefit
of the Company to take and hold such Securities subject to, and to be bound by, the terms and
conditions set forth in this Warrant to the same extent as if the transferee were the original
Holder hereunder.

          (b) Permitted Transfers. Permitted transfers include (i) a transfer not involving a change in
beneficial ownership, or (ii) transactions involving the distribution without consideration of
Securities by any Holder to an affiliate; provided, in each case, that the Holder shall give
written notice to the Company of

-4-

 

the Holder’s intention to effect such disposition and shall have
furnished the Company with a detailed description of the manner and circumstances of the proposed
disposition.

          (c) Investment Representation Statement. Unless the rights under this Warrant are exercised
pursuant to an effective registration statement under the Securities Act that includes the Shares
with respect to which the Warrant was exercised, it shall be a condition to any exercise of the
rights under this Warrant that the Holder shall have confirmed to the satisfaction of the Company
in writing, substantially in the form of Exhibit A-1, that the Shares so purchased are being
acquired solely for the Holder’s own account and not as a nominee for any other party, for
investment and not with a view toward distribution or resale and that the Holder shall have
confirmed such other matters related thereto as may be reasonably requested by the Company.

          (d) Securities Law Legend. The Securities shall (unless otherwise permitted by the provisions
of this Warrant) be stamped or imprinted with a legend substantially similar to the following (in
addition to any legend required by state securities laws):

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY
NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED
UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS IN ACCORDANCE WITH APPLICABLE
REGISTRATION REQUIREMENTS OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY
REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR
TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE
SECURITIES LAWS. THIS CERTIFICATE MUST BE SURRENDERED TO THE COMPANY OR ITS TRANSFER AGENT
AS A CONDITION PRECEDENT TO THE SALE, TRANSFER, PLEDGE OR HYPOTHECATION OF ANY INTEREST IN
ANY OF THE SECURITIES REPRESENTED HEREBY.

          (e) Instructions Regarding Transfer Restrictions. The Holder consents to the Company making a
notation on its records and giving instructions to any transfer agent in order to implement the
restrictions on transfer established in this Section 5.

          (f) Removal of Legend. The legend referring to federal and state securities laws identified in
Section 5(d) stamped on a certificate evidencing the Shares and the stock transfer instructions and
record notations with respect to such securities shall be removed and the Company shall issue a
certificate without such legend to the holder of such securities if (i) such securities are
registered under the Securities Act, or (ii) such holder provides the Company with an opinion of
counsel reasonably acceptable to the Company to the effect that a sale or transfer of such
securities may be made without registration or qualification.

     6. Adjustments. Subject to the expiration of this Warrant pursuant to Section 8, the number
and kind of shares purchasable hereunder and the Exercise Price therefor are subject to adjustment
from time to time, as follows:

          (a) Merger or Reorganization. If at any time there shall be any reorganization,
recapitalization, merger or consolidation (a “Reorganization”) involving the Company (other than as
otherwise provided for herein or as would cause the expiration of this Warrant under Section 8) in
which shares of the Company’s stock are converted into or exchanged for securities, cash or other
property, then, as a part of such Reorganization, lawful provision shall be made so that the Holder
shall thereafter be entitled to

-5-

 

receive upon exercise of this Warrant, the kind and amount of
securities, cash or other property of the successor corporation resulting from such Reorganization,
equivalent in value to that which a holder of the Shares deliverable upon exercise of this Warrant
would have been entitled in such Reorganization if the right to purchase the Shares hereunder had
been exercised immediately prior to such Reorganization. In any such case, appropriate adjustment
(as determined in good faith by the Board of Directors of the successor corporation) shall be made
in the application of the provisions of this Warrant with respect to the rights and interests of
the Holder after such Reorganization to the end that the provisions of this Warrant shall be
applicable after the event, as near as reasonably may be, in relation to any shares or other
securities deliverable after that event upon the exercise of this Warrant.

          (b) Reclassification of Shares. If the securities issuable upon exercise of this Warrant are
changed into the same or a different number of securities of any other class or classes by
reclassification, capital reorganization, conversion of all outstanding shares of the relevant
class or series (other than as would cause the expiration of this Warrant pursuant to Section 8) or
otherwise (other than as otherwise provided for herein) (a “Reclassification”), then, in any such
event, in lieu of the number of Shares which the Holder would otherwise have been entitled to
receive, the Holder shall have the right thereafter to exercise this Warrant for a number of shares
of such other class or classes of stock that a holder of the number of securities deliverable upon
exercise of this Warrant immediately before that change would have been entitled to receive in such
Reclassification, all subject to further adjustment as provided herein with respect to such other
shares.

          (c) Subdivisions and Combinations. In the event that the outstanding shares of the securities
issuable upon exercise of this Warrant are subdivided (by stock split, by payment of a stock
dividend or otherwise) into a greater number of shares of such securities, the number of Shares
issuable upon exercise of the rights under this Warrant immediately prior to such subdivision
shall, concurrently with the effectiveness of such subdivision, be proportionately increased, and
the Exercise Price shall be proportionately decreased, and in the event that the outstanding shares
of the securities issuable upon exercise of this Warrant are combined (by reclassification or
otherwise) into a lesser number of shares of such securities, the number of Shares issuable upon
exercise of the rights under this Warrant immediately prior to such combination shall, concurrently
with the effectiveness of such combination, be proportionately decreased, and the Exercise Price
shall be proportionately increased.

          (d) Redemption. In the event that all of the outstanding shares of the securities issuable
upon exercise of this Warrant are redeemed in accordance with the Company’s certificate of
incorporation, this Warrant shall thereafter be exercisable for a number of shares of the Company’s
Class A Common Stock equal to the number of shares of Class A Common Stock that would have been
received if this Warrant had been exercised in full immediately prior to such redemption.

          (e) Notice of Adjustments. Upon any adjustment in accordance with this Section 6, the Company
shall give notice thereof to the Holder, which notice shall state the event giving rise to the
adjustment, the Exercise Price as adjusted and the number of securities or other property
purchasable upon
the exercise of the rights under this Warrant, setting forth in reasonable detail the method
of calculation of each. The Company shall, upon the written request of any Holder, furnish or cause
to be furnished to such Holder a certificate setting forth (i) such adjustments, (ii) the Exercise
Price at the time in effect and (iii) the number of securities and the amount, if any, of other
property that at the time would be received upon exercise of this Warrant.

     7. Notification of Certain Events. Prior to the expiration of this Warrant pursuant to Section
8, in the event that the Company shall authorize:

          (a) the issuance of any dividend or other distribution on the capital stock of the Company
(other than (i) dividends or distributions otherwise provided for in Section 6, (ii) repurchases of
capital stock

-6-

 

issued to or held by employees, officers, directors or consultants of the Company or
its subsidiaries upon termination of their employment or services pursuant to agreements providing
for the right of said repurchase; (iii) repurchases of capital stock issued to or held by
employees, officers, directors or consultants of the Company or its subsidiaries pursuant to rights
of first refusal or first offer contained in agreements providing for such rights; or (iv)
repurchases of capital stock of the Company in connection with the settlement of disputes with any
stockholder), whether in cash, property, stock or other securities; or

          (b) the voluntary liquidation, dissolution or winding up of the Company.

the Company shall send to the Holder of this Warrant at least twenty (20) days prior written notice
of the date on which a record shall be taken for any such dividend or distribution specified in
clause (a) or the expected effective date of any such other event specified in clause (b), as
applicable. The notice provisions set forth in this section may be shortened or waived
prospectively or retrospectively by the consent of the Holder of this Warrant.

     8. Expiration of the Warrant. This Warrant shall expire and shall no longer be exercisable as
of the earlier of (i) 5:00 p.m., Pacific time, on __________, (ii) the Company’s initial public
offering, or (iii) a transaction or series of related transactions in which a person, or a group of
affiliated persons, acquires from stockholders of the Company shares representing more than fifty
percent (50%) of the outstanding voting power of the Company or acquires all or substantially all
of the assets of the Company.

     9. No Rights as a Stockholder. Nothing contained herein shall entitle the Holder to any rights
as a stockholder of the Company or to be deemed the holder of any securities that may at any time
be issuable on the exercise of the rights hereunder for any purpose nor shall anything contained
herein be construed to confer upon the Holder, as such, 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 to receive dividends or
subscription rights or any other rights of a stockholder of the Company until the rights under the
Warrant shall have been exercised and the Shares purchasable upon exercise of the rights hereunder
shall have become deliverable as provided herein.

     10. Representations and Warranties of the Holder. By acceptance of this Warrant, the Holder
represents and warrants to the Company as follows:

          (a) Purchase for Own Account. This Warrant and the securities to be acquired upon
exercise of this Warrant by the Holder will be acquired for investment for the Holder’s account,

purpose of acquiring this Warrant or the Shares.

          (b) Disclosure of Information. The Holder has received or has had full access to all the
information it considers necessary or appropriate to make an informed investment decision with
respect to the acquisition of this Warrant and its underlying securities. The Holder further has
had an opportunity to ask questions and receive answers from the Company regarding the terms and
conditions of the offering of this Warrant and its underlying securities and to obtain additional

unless subsequently registered under the Securities Act and qualified under applicable state
securities laws, or unless exemption from such registration and qualification are otherwise

INVESTMENT REPRESENTATION STATEMENT

	 	 	 

	INVESTOR:

	 	 
	 
	 	 
	COMPANY:

	 	KIOR, INC.
	 
	 	 
	SECURITIES:

	 	THE WARRANT ISSUED ON ____________ (THE “WARRANT”) AND THE
SECURITIES ISSUED OR ISSUABLE UPON EXERCISE THEREOF (INCLUDING
UPON SUBSEQUENT CONVERSION OF THOSE SECURITIES)
	 
	 	 
	DATE:

	 	__________________

     In connection with the purchase or acquisition of the above-listed Securities, the undersigned
Investor represents and warrants to, and agrees with, the Company as follows:

     1. No Registration. The Investor understands that the Securities have not been, and will not
be, registered under the Securities Act of 1933, as amended (the “Securities Act”), by reason of a
specific exemption from the registration provisions of the Securities Act, the availability of
which depends upon, among other things, the bona fide nature of the investment intent and the
accuracy of the Investor’s representations as expressed herein or otherwise made pursuant hereto.

     2. Investment Intent. The Investor is acquiring the Securities for investment for its own
account, not as a nominee or agent, and not with a view to, or for resale in connection with, any
distribution thereof. The Investor has no present intention of selling, granting any participation
in, or otherwise distributing the Securities, nor does it have any contract, undertaking, agreement
or arrangement for the same.

     3. Investment Experience. The Investor has substantial experience in evaluating and investing
in private placement transactions of securities in companies similar to the Company, and has such
knowledge and experience in financial or business matters so that it is capable of evaluating the
merits and risks of its investment in the Company and protecting its own interests.

     4. Speculative Nature of Investment. The Investor understands and acknowledges that its
investment in the Company is highly speculative and involves substantial risks. The Investor can
bear the economic risk of its investment and is able, without impairing its financial condition, to
hold the Securities for an indefinite period of time and to suffer a complete loss of its
investment.

     5. Access to Data. The Investor has had an opportunity to ask questions of officers of the
Company, which questions were answered to its satisfaction. The Investor understands that any such
discussions, as well as any information issued by the Company, were intended to describe certain
aspects of the Company’s business and prospects, but were not necessarily a thorough or exhaustive
description. The Investor acknowledges that any business plans prepared by the Company have been,
and continue to be, subject to change and that any projections included in such business plans or
otherwise are necessarily speculative in nature, and it can be expected that some or all of the
assumptions underlying the projections will not materialize or will vary significantly from actual
results.

A-1-1

 

     6. Accredited Investor. The Investor is an “accredited investor” within the meaning of
Regulation D, Rule 501(a), promulgated by the Securities and Exchange Commission and agrees to
submit to the Company such further assurances of such status as may be reasonably requested by the
Company.

     7. Residency. The residency of the Investor (or, in the case of a partnership or corporation,
such entity’s principal place of business) is correctly set forth on the signature page hereto.

     8. Restrictions on Resales. The Investor acknowledges that the Securities must be held
indefinitely unless subsequently registered under the Securities Act or an exemption from such
registration is available. The Investor is aware of the provisions of Rule 144 promulgated under
the Securities Act, which permit resale of shares purchased in a private placement subject to the
satisfaction of certain conditions, which may include, among other things, the availability of
certain current public information about the Company; the resale occurring not less than a
specified period after a party has purchased and paid for the security to be sold; the number of
shares being sold during any three-month period not exceeding specified limitations; the sale being
effected through a “broker’s transaction,” a transaction directly with a “market maker” or a
“riskless principal transaction” (as those terms are defined in the Securities Act or the
Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder);
and the filing of a Form 144 notice, if applicable. The Investor acknowledges and understands that
the Company may not be satisfying the current public information requirement of Rule 144 at the
time the Investor wishes to sell the Securities and that, in such event, the Investor may be
precluded from selling the Securities under Rule 144 even if the other applicable requirements of
Rule 144 have been satisfied. The Investor understands and acknowledges that, in the event the
applicable requirements of Rule 144 are not met, registration under the Securities Act or an
exemption from registration will be required for any disposition of the Securities. The Investor
understands that, although Rule 144 is not exclusive, the Securities and Exchange Commission has
expressed its opinion that persons proposing to sell restricted securities received in a private
offering other than in a registered offering or pursuant to Rule 144 will have a substantial burden
of proof in establishing that an exemption from registration is available for those offers or sales
and that those persons and the brokers who participate in the transactions do so at their own risk.

     9. No Public Market. The Holder understands and acknowledges that no public market now exists
for any of the securities issued by the Company and that the Company has made no assurances that a
public market will ever exist for the Company’s securities.

     10. Brokers and Finders. The Investor has not engaged any brokers, finders or agents in
connection with the Securities, and the Company has not incurred nor will incur, directly or
indirectly, as a result of any action taken by the Investor, any liability for brokerage or
finders’ fees or agents’ commissions or any similar charges in connection with the Securities.

     11. Legal Counsel. The Investor has had the opportunity to review the Warrant, the exhibits
and schedules attached thereto and the transactions contemplated by the Warrant with its own legal
counsel. The Investor is not relying on any statements or representations of the Company or its
agents for legal advice with respect to this investment or the transactions contemplated by the
Warrant.

     12. Tax Advisors. The Investor has reviewed with its own tax advisors the U.S. federal, state
and local and non-U.S. tax consequences of this investment and the transactions contemplated by the
Warrant. With respect to such matters, the Investor relies solely on such advisors and not on any
statements or representations of the Company or any of its agents, written or oral. The Investor
understands that it (and not the Company) shall be responsible for its own tax liability that may
arise as a result of this investment or the transactions contemplated by the Warrant.

Notwithstanding anything in the Loan Documents to the contrary, Lender’s obligation to make any
Advances or to lend the undisbursed portion of the Commitment shall terminate on the Commitment
Termination Date. Repaid principal of the Advances may not be re-borrowed.

2.2 The Advances. A Note setting forth the specific terms of repayment will evidence each Advance. No Advance will
be made for less than $100,000, unless less than $100,000 remains available under the Commitment
for borrowing. Absence of a Note evidencing any portion of the Loan shall not impair Borrower’s
obligation to repay it to Lender.

2.3 Terms of Payment, Repayment.

     (a) Repayment. Borrower shall repay the principal and pay interest on each Advance on the
terms set forth in the applicable Note. Amounts not paid when due hereunder or under the Note shall
bear interest at the Default Rate. If a court of competent jurisdiction determines that Lender has
received payments that, if interest, would exceed the maximum lawfully permitted, Lender will
instead apply such money to fees and expenses and then to early prepayment of principal (without
any Prepayment Fee (as defined in the Note).

     (b) ACH. All payments due to Lender must be, at Lender’s option, paid to Lender in cash or
through ACH. Borrower shall execute and deliver the ACH Authorization Form substantially in the
form of Exhibit G. If the ACH payment arrangement is terminated for any reason, Borrower shall make
all payments due to Lender at Lender’s address specified in Section 11.

3

 

     (c) Default Rate. While an Event of Default has occurred and is continuing, interest on the
Loan shall be increased to the Default Rate. Lender’s failure to charge or accrue interest at the
Default Rate during the existence of a Default shall not be deemed a waiver by Lender of its right
or claim thereto.

     (d) Date. Whenever any payment due under the Loan Documents is due on a day other than a
business day, such payment shall be made on the next succeeding business day, and such extension of
time shall be included in the computation of interest or fees, as the case may be.

2.4 Fees. Borrower shall pay to Lender the following:

     (a) Commitment Fee. The Commitment Fee, which has been previously paid by Borrower, and shall
be applied by Lender to Lender’s Expenses and other Obligations;

     (b) Late Fee. On demand, a late charge on any sums due hereunder that are not paid when due,
in an amount equal to 2% of the past due amount, payable on demand.

     (c) Lender’s Expenses. When requested, all Lender’s Expenses. Lender’s Expenses not paid when
due shall bear interest as principal at the Default Rate.

3. Conditions of Advances; Procedure For Requesting Advances

3.1 Conditions Precedent to any and all Advances. The obligation of Lender to make any Advances is subject to each and every of the following
conditions precedent in form and substance satisfactory to Lender in its sole discretion: (i) this
Agreement, a Note evidencing the Advance, the Wan-ant attached hereto as Exhibit C, and all other
UCC financing statements, and other documents required or as specified herein have been duly
authorized, executed and delivered; (ii) Lender’s receipt of all vendor invoices, bills of sale,
receipts, agreements, proof of payment, and other documents as Lender shall reasonably request to
evidence the ownership by Borrower of, the payment in full of the purchase price of, and the fair
market value of, Collateral; (iii) no Default or Event of Default has occurred and is continuing;
(iv) delivery of a Notice of Borrowing with respect to the proposed Advance; (v) Lender’s security
interests in the Collateral are valid and first priority, except for Permitted Liens; and (vi) all
such other items as Lender may reasonably deem necessary or appropriate have been delivered or
satisfied. The extension of an Advance prior to the receipt by Lender of any of the foregoing shall
not constitute a waiver by Lender of Borrower’s obligation to deliver such item.

3.2 Procedure for Making Advances. Borrower shall provide Lender an irrevocable Notice of Borrowing at least 15 business days prior
to the desired Funding Date for any Advance, including therewith all vendor invoices, bills of
sale, receipts, agreements, proof of payment, and other documents to evidence the ownership of such
equipment by Borrower for which Borrower is requesting an Advance hereunder provided such financed
equipment is delivered to Borrower within 120 days of the Funding Date for such equipment. Lender
shall only be required to make Advances hereunder based upon written requests which comply with the
terms and exhibits of this Loan Agreement (as the same may be amended from time to time), and which
are submitted and signed by a Responsible Officer. Borrower shall execute and deliver to Lender a
Note and such other documents and instruments as Lender may reasonably require for each Advance
made. With respect to the initial Advance hereunder, Lender agrees to finance equipment delivered
to Borrower since January 1, 2008, provided the Notice of Borrowing for such Advance is delivered
to Lender within 30 days from the date of this Agreement.

4. Creation of Security Interest

security interest in all present and future Collateral in order to secure prompt, full, faithful
and timely payment and performance of all Obligations.

computer files, and to make copies, and to test, inspect and appraise the Collateral, in order to
verify any matter relating to Borrower or the Collateral.

4.3 Authorization to File Financing Statements. Borrower irrevocably authorizes Lender at any time and from time to time to file in any
jurisdiction any financing statements and amendments that: (i) name Collateral as collateral
thereunder, regardless of whether any particular Collateral falls within the scope of the UCC; (ii)
contain any other information required

4

 

by the UCC for sufficiency or filing office acceptance,
including organization identification numbers; and (iii) contain such language as Lender reasonably
determines is helpful in protecting or preserving rights against third parties.

respects for the periods indicated.

5.8 Solvency. Borrower is solvent and able to pay its debts (including trade debts) as they come due.

in such certificates or statements not misleading.
