outstanding options, licenses, agreements, claims, encumbrances or shared ownership of
interests of any kind relating to anything referred to above in this Section 2.10, nor are
any of the Company Parties bound by or a party to any options, licenses, agreements or
warranties of any kind with respect to the patents, trademarks, service marks, trade names,
domain names, copyrights, trade secrets, licenses, information, proprietary rights and/or
processes of any other person or entity, except, in either case, for standard, generally
commercially available, “off-the-shelf” third party products that are not and will not to
any extent be part of any product, service or intellectual property offering of the Company.
Except as set forth on the Schedule of Exceptions, none of the Company Parties has received
any communications in writing alleging that a Company Party has violated, or by conducting
its business as proposed, would violate any of the patents, trademarks, service marks, trade
names, copyrights or
trade secrets or other proprietary rights of any other person or entity, and the
Company is not aware of any potential basis for such an allegation or of any reason to
believe that such an allegation may be forthcoming. The Company is not aware that any of
its or either of the Subsidiaries’ employees is obligated under any contract (including
licenses, covenants or commitments of any nature) or other agreement, or subject to any
judgment, decree or order of any court or administrative agency, that would interfere with
the use of his or her best efforts to promote the interests of the Company and its
Subsidiaries or that would conflict with the Company’s and the Subsidiaries’ business as now
conducted and as proposed to be conducted. Neither the execution nor delivery of this
Agreement, nor the carrying on of the Company’s business by the employees of the Company,
nor the conduct of the Company’s business as proposed, will, to the Company’s knowledge,
conflict with or result in a breach of the terms, conditions or provisions of, or constitute
a default under, any contract, covenant or instrument under which any of such employees is
now obligated. The Company does not believe it is or will be necessary to use any
inventions of any of its employees (or persons it currently intends to hire) made prior to
their employment by the Company. The

8

 

Company is not subject to any “open source” or
“copyleft” obligations, or otherwise required (now or in the future) to make any public
disclosure or general availability of source code either used or developed by, the Company.

     2.11 Compliance with Other Instruments; No Conflicts. None of the Company Parties is in violation of any provision of its respective
articles of incorporation or bylaws or comparable governing documents, or in any material
respect in violation or default of any instrument, judgment, order, writ, decree or contract
to which it is a party or by which it is bound, or of any provision of any federal, state or
local statute, rule or regulation applicable to any of the Company Parties. The execution,
delivery and performance of this Agreement and the Ancillary Agreements, and the
consummation of the transactions contemplated hereby and thereby will not result in any such
violation or default or be in conflict with or constitute, with or without the passage of
time and giving of notice, either a default under any such provision, instrument, judgment,
order, writ, decree or contract or an event that results in the creation of any lien, charge
or encumbrance upon any assets of any of the Company Parties or the suspension, revocation,
impairment, forfeiture, or nonrenewal of any material permit, license, authorization, or
approval applicable to any of the Company Parties, their business or operations or any of
their assets or properties.

     2.12 Certain Contracts and Arrangements. Except as set forth in this Agreement, the Ancillary Agreements or as set forth in
the Schedule of Exceptions, none of the Company Parties is a party or subject to or bound
by:

     (a) any contract, agreement or understanding entered into in the ordinary
course of business involving a potential commitment, obligation or payment by or to
such Company Party in excess of $200,000;

     (b) any (i) contract, agreement or understanding (other than contracts,
agreements or understandings entered into in the ordinary course of business) or
(ii) instrument, judgment, order, writ or decree; in each case involving a potential
commitment, obligation or payment by or to such Company Party in excess of $100,000;

     (c) any material license of any patent, copyright, trade secret or other
proprietary right to or from such Company Party (other than the license to such
Company Party of standard, generally commercially available, “off-the-shelf” third
party products that are not and will not to any extent be part of any product,
service or intellectual property offering of any of the Company Parties);

     (d) provisions materially restricting the development, manufacture or
distribution of such Company Parties’ products or services;

     (e) indemnification by such Company Party with respect to infringements of
proprietary rights;

     (f) any indenture, mortgage, promissory note, loan agreement, or guaranty;

9

 

     (g) any employment contracts, noncompetition agreements, severance agreements
or other agreements with present or former officers, directors, employees or
shareholders of such Company Party or persons related to or affiliated with such
persons;

     (h) any stock redemption or purchase agreements or other agreements affecting
or relating to the capital stock of such Company Party;

     (i) any benefit plan relating to the employees of such Company Party, including
pension, profit sharing, other deferred compensation plan or arrangement, bonus,
retirement, health insurance, severance or stock option plans;

     (j) any joint venture or partnership agreement;

     (k) any manufacturer, development or supply agreement involving a potential
commitment, obligation or payment by or to such Company Party in excess of $100,000;
or

     (l) any acquisition, merger or similar agreement.

     All contracts, agreements, leases and instruments set forth on the Schedule of Exceptions are
valid and are in full force and effect and constitute legal, valid and binding obligations of the
Company and, to the knowledge of the Company, of the other parties, and are enforceable in
accordance with their respective terms.

     2.13 Related-Party Transactions. No employee, officer, director or shareholder of any of the Company Parties owning
two percent (2%) or more of the total outstanding equity of any of the Company Parties (a
“Related Party”) or member of such Related Party’s immediate family, or any
corporation, partnership or other entity in which such Related Party is an officer, director
or partner, or in which such Related Party has significant ownership interests or otherwise
controls, is indebted to any of the Company Parties, nor is any of the Company Parties
indebted (or committed to make loans or extend or guarantee credit) to any of them, other
than (a) for payment of salary for services previously rendered in the ordinary course of
business, (b) as reimbursement for reasonable expenses incurred on behalf of such Company
Party in the ordinary course of business, (c) for other standard employee benefits made
generally available to all employees (not including stock option agreements outstanding
under any stock option plan approved by the Board of Directors of the Company), or (d) such
other employee benefits as may be provided for in any written employment agreement or other
written instrument. To the Company’s knowledge, none of such persons has any direct or
indirect ownership interest in any firm or corporation with which any of the Company Parties
is affiliated or with which any of the Company Parties has a business relationship, or any
firm or corporation that competes with any of the Company Parties, except that employees,
officers, directors or shareholders of each of the Company Parties and members of such
Related Party’s immediate families may own stock in publicly traded companies that may
compete with the Company Parties. No Related Party or member of their immediate family is
directly or indirectly interested in any material contract with

10

 

any of the Company Parties.
The terms of any transaction with a Related Party (including, without limitation,
transactions between the Company and each of the Subsidiaries) are on arms’ length for any
purpose, as reasonably determined based on professional advice, and have been approved by
the Company or the Subsidiary, as the case may be, in accordance with applicable laws, rules
and regulations. No terms of such transactions would reasonably be expected to result in a
Material Adverse Effect.

     2.14 Permits. Each of the Company Parties has all franchises, permits, licenses, and any similar
authority necessary for the conduct of its business as now conducted and as proposed to be
conducted, the lack of which could have a Material Adverse Effect. None of the Company
Parties is in default in any material respect under any of such franchises, permits,
licenses, or other similar authority.

     2.15 Safety Laws. None of the Company Parties is in violation of any applicable statute, law or
regulation relating to the occupational health and safety, which violation would have a
Material Adverse Effect and no material expenditures are or, to the Company’s knowledge,
will be required in order to comply with any such existing statute, law or regulation.

     2.16 Environmental Matters.

     (a) The Company Parties have complied with all applicable Environmental Laws
(as defined below), except for violations of Environmental Laws that, individually
or in the aggregate, have not had and would not reasonably be expected to have a
Material Adverse Effect. There is no pending or, to best of the Company’s
knowledge, threatened civil or criminal litigation, written notice of violation,
formal administrative proceeding, or investigation, inquiry or information request
by any federal, state or local court, arbitrational tribunal, administrative agency
or commission or other governmental or regulatory authority or agency (each a
“Governmental Entity”) that would be reasonably expected to have a Material
Adverse Effect, and no expenditures that would be reasonably expected to have a
Material Adverse Effect are, or to the Company’s knowledge will be, required to
comply with any existing statute, law or regulation relating to any Environmental
Law involving the Company Parties. For purposes of this Agreement, “Environmental
Law” shall mean any federal, state or local law, statute, rule or regulation or the
common law relating to the environment or occupational health and safety, including
any statute, regulation, administrative decision or order pertaining to
(i) treatment, storage, disposal, generation and transportation of industrial, toxic
or hazardous materials or substances or solid or hazardous waste; (ii) air, water
and noise pollution; (iii) groundwater and soil contamination; (iv) the release or
threatened release into the environment of industrial, toxic or hazardous materials
or substances, or solid or hazardous waste, including emissions, discharges,
injections, spills, escapes or dumping of pollutants, contaminants or chemicals;
(v) the protection of wild life, marine life and wetlands, including all endangered
and threatened species; (vi) storage tanks, vessels, containers, abandoned or
discarded barrels and other closed receptacles; (vii) health and safety of employees
and other persons; and

11

 

(viii) manufacturing, processing, using, distributing,
treating, storing, disposing, transporting or handling of materials regulated under
any law as pollutants, contaminants, toxic or hazardous materials or substances or
oil or petroleum products or solid or hazardous waste. As used above, the terms
“release” and “environment” shall have the meaning set forth in the federal
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended (“CERCLA”).

     (b) There are no past or present Environmental Claims, actions, activities,
circumstances, conditions, events or incidents, including the release, emission,
discharge, presence or disposal of any Materials of Environmental Concern (as
defined below), that would reasonably be expected to have a Material Adverse Effect.
For purposes of this Agreement, (i) “Materials of Environmental Concern”
shall mean chemicals; pollutants; contaminants; wastes; toxic or hazardous
substances, materials and wastes; petroleum and petroleum products; asbestos and
asbestos-containing materials; polychlorinated biphenyls; lead and lead-based paints
and materials; and radon; and (ii) “Environmental Claim” shall mean any
claim, action, cause of action, investigation or notice (written or oral) by any
person or entity alleging actual or potential liability for investigatory, cleanup
or governmental response costs, or natural resources or property damages, or
personal injuries, attorney’s fees or penalties arising from or relating
to (A) the presence, or release into the environment, of any Materials of
Environmental Concern, now or in the past, (B) circumstances forming the basis of
any violation, or alleged violation, of any Environmental Law, or (C) the liability
of any Company Party for any violation, or alleged violation, of any Environmental
Law by any person or entity (whether contractual, by operation of law or otherwise).

     (c) Except in accordance with applicable Environmental Law, and so as not to
give rise to an Environmental Claim that would reasonably be expected to have a
Material Adverse Effect, (i) Materials of Environmental Concern have not been
generated, used, treated or stored on, transported to or from, or released on, at or
from, any past or present facilities, properties or operations of any of the Company
Parties and (ii) Materials of Environmental Concern have not been disposed of on any
past or present facilities, properties or operations of any of the Company Parties.

     (d) Except as set forth in the Schedule of Exceptions, none of the Company
Parties is a party to or bound by any court order, administrative order, consent
order or other agreement between any such Company Party and any Governmental Entity
entered into in connection with any legal obligation or liability arising under any
Environmental Law that would reasonably be expected to have a Material Adverse
Effect.

     (e) Set forth in the Schedule of Exceptions is a list of all documents known to
the Company (whether in hard copy or electronic form) that contain any environmental
reports, investigations and audits relating to premises currently or

12

 

previously
owned or operated by the Company Parties (whether conducted by or on behalf of such
Company Parties or a third party, and whether done at the initiative of such Company
Parties or directed by a Governmental Entity or other third party) which were issued
or conducted during the past five years and which any of the Company Parties has
possession of or access to. A complete and accurate copy of each such document has
been provided to or made available to the Purchasers.

     2.17 Manufacturing, Marketing and Development Rights. The Company has not granted rights to manufacture, produce, assemble, license,
market, or sell its products to any other person and is not bound by any agreement that
affects the Company’s exclusive right to develop, manufacture, assemble, distribute, market
or sell its products.

     2.18 Registration Rights. Except as provided in the Investors’ Rights Agreement, the Company has not granted
or agreed to grant any registration rights, including piggyback rights, to any person or
entity.

     2.19 Corporate Documents. The Articles of Incorporation and bylaws of the Company are in the form previously
provided to counsel for each Investor.

     2.20 Title to Property and Assets. Each of the Company Parties owns its property and assets free and clear of all
mortgages, liens, loans and encumbrances, except such encumbrances and liens that arise in
the ordinary course of business and do not materially impair such Company Parties’ ownership
or use of such property or assets. With respect to the property and assets it leases, each
of the Company Parties is in compliance with such leases and holds a valid leasehold
interest free of any liens, claims or encumbrances.

     2.21 Financial Statements. The Company has delivered to each Investor (a) its audited consolidated financial
statements (balance sheet and income and cash flow statements, including notes thereto) at
March 31, 2007 and 2006 and for the fiscal years then ended, and (b) interim, unaudited
financial statements as of May 31, 2007 (the “Financial Statements”). The Financial
Statements have been prepared in accordance with United States generally accepted accounting
principles (“GAAP”) applied on a consistent basis throughout the periods indicated.
The Financial Statements fairly present the financial condition and operating results of the
Company and the Subsidiaries on a consolidated basis as of the dates, and for the periods,
indicated therein. Except as set forth in the Financial Statements, the Company has no
material liabilities, contingent or otherwise, other than (i) liabilities incurred in the
ordinary course of business subsequent to March 31, 2007 and (ii) obligations under
contracts and commitments incurred in the ordinary course of business and not required under
GAAP to be reflected in the Financial Statements, and which, individually or in the
aggregate, are not material to the financial condition or operating results of the Company.
The Company maintains a standard system of accounting established and administered in
accordance with GAAP.

     2.22 Changes. Since March 31, 2007, there has not been:

13

 

     (a) any change in the assets, liabilities, financial condition or operating
results of the Company from that reflected in the Financial Statements, except
changes in the ordinary course of business that have not had a Material Adverse
Effect;

     (b) any damage, destruction or loss, whether or not covered by insurance, of
any material asset of the Company Parties;

     (c) any waiver by any of the Company Parties of a valuable right or of a
material debt owed to it;

     (d) any satisfaction or discharge of any lien, claim or encumbrance or payment
of any obligation by any of the Company Parties, except in the ordinary course of
business and that has not had a Material Adverse Effect;

     (e) any material change or amendment to a material contract;

     (f) any material change in any compensation arrangement or agreement with any
employee, officer or director;

     (g) any sale, assignment or transfer of any patents, trademarks, copyrights,
trade secrets or other intangible assets;

     (h) any resignation or termination of employment of any key officer of the
Company; and the Company, to its knowledge, does not know of the impending
resignation or termination of employment of any such officer or key employee of the
Company;

     (i) receipt of notice that there has been a loss of, or material order
cancellation by, any major customer of the Company;

     (j) any mortgage, pledge, transfer of a security interest in, or lien, created

assets, except liens for taxes not yet due or payable and liens that arise in the
ordinary course of business and do not materially impair such Company Parties’
ownership or use of such property or assets;

     (k) any loans or guarantees made by any of the Company Parties to or for the
benefit of its employees, officers or directors, or any members of their immediate
families, other than travel advances and other advances made in the ordinary course
of its business;

     (l) any declaration, setting aside or payment or other distribution in respect
of any of the Company’s capital stock, or any direct or indirect redemption,
purchase or other acquisition of any of such stock by the Company, except to the
extent specifically contemplated by this Agreement;

14

 

     (m) to the Company’s knowledge, any other event or condition of any character
that would be reasonably likely to have a Material Adverse Effect; or

     (n) any agreement or commitment by any of the Company Parties to do any of the
things described in this Section 2.22.

     2.23 Employee Benefit Plans. None of the Company Parties has any Employee Benefit Plan as defined in the Employee
Retirement Income Security Act of 1974.

     2.24 Tax. None of the Company Parties is currently liable for any tax (whether income tax,
capital gains tax, or otherwise), and any taxes which were due in the past (if at all) have
been timely paid by the Company. Each of the Company Parties has accurately prepared and
timely effected and filed all necessary filings (including income and payroll tax returns
and filings that it is required to file) and reports (the “Tax Reports”) with the
appropriate tax authorities and has paid or made adequate provision for the payment of all
amounts due pursuant to the Tax Reports as well as other taxes, assessments and governmental
charges which have become due or payable. The Tax Reports are true and complete in all
material respects and accurately reflect all liability for taxes for the periods covered
thereby. None of the Company Parties’ tax returns have been audited by any taxing authority
and none of the Company Parties has been advised that any of such Tax Reports have been or
are being so audited. Each of the Company Parties has withheld or collected for each
payment made to each of its employees, the amount of all taxes (including, but not limited
to, federal income taxes, Federal Insurance Contribution Act taxes and Federal Unemployment
Tax Act taxes) required to be withheld or collected therefrom and has timely paid the same
to the proper tax receiving officers or authorized depositories. None of the Company
Parties has notice that any tax return or report is under examination by any governmental
entity.

     2.25 Insurance. Each of the Company Parties has adequate insurance, with financially sound and
reputable insurers, with respect to its properties, business and operations that are of a
character customarily insured by entities engaged in the same or a similar business
similarly situated, against loss or damage of the kinds customarily insured against by such
entities, which insurance is of such types as are customarily carried under similar
circumstances by such other entities.

     2.26 Minute Books. The minute books of each of the Company Parties provided to the Investors contain a
complete summary of all meetings of directors and shareholders since January 1, 2005 and
reflect all transactions referred to in such minutes accurately in all material respects.

     2.27 Labor Agreements and Actions. None of the Company Parties is bound by or subject to (and none of its assets or
properties is bound by or subject to) any written or oral, express or implied, contract,
commitment or arrangement with any labor union, and no labor union has requested or, to the
Company’s knowledge, has sought to represent any of the employees, representatives or agents
of any of the Company Parties. There is no strike or other labor dispute involving any of
the Company Parties pending, or to the Company’s knowledge, threatened, that could have a
Material Adverse Effect,

15

 

nor is the Company aware of any labor organization activity
involving the employees of any of the Company Parties. The Company is not aware that any
officer or key employee, or that any group of key employees, intends to terminate their
employment with any of the Company Parties, nor
does the Company have a present intention to terminate the employment of any of the
foregoing. The employment of each officer and employee of each of the Company Parties is
terminable at the will of such Company Party. To the Company’s knowledge, each of the
Company Parties has complied in all material respects with all applicable federal, state and
provincial equal employment opportunity and other laws related to employment. None of the
Company Parties is subject to, and none of their employees benefit from, any collective
bargaining agreement by way of any applicable employment laws and regulations and extension
orders. All employees of the Company whose employment responsibility requires access to
confidential or proprietary information of the Company have executed and delivered Propriety
Information and Intellectual Property Agreements in the form of Exhibit D
(“Proprietary Information Agreements”) and all of such agreements are in full force
and effect. None of the employees of the Company is represented by any labor union, and
there is no labor strike or other labor trouble pending with respect to the Company
(including, without limitation any organizational drive) or, to the best of the Company’s
knowledge, threatened.

     2.28 Significant Customers and Suppliers. Section 2.28 of the Schedule of Exceptions sets forth a list of (a) each customer
that accounted for more than one percent (1%) of the consolidated revenues of the Company
during the last full fiscal year or the interim period through May 31, 2007 and the amount
of revenues accounted for by such customer during each such period and (b) each supplier
that is the sole supplier of any significant product to the Company or a Subsidiary. No
such customer or supplier has indicated within the past year that it will stop, or decrease
the rate of, buying products or supplying products, as applicable, to the Company or any
Subsidiary. No unfilled customer order or commitment obligating the Company or any
Subsidiary to process, manufacture or deliver products or perform services will result in a
loss to the Company or any Subsidiary upon completion of performance. No purchase order or
commitment of the Company or any Subsidiary is in excess of normal requirements, nor are
prices provided therein in excess of current market prices for the products or services to
be provided thereunder.

     2.29 Inventory. All inventory of the Company and the Subsidiaries, whether or not reflected on the
Financial Statements, consists of a quality and quantity usable and saleable in the ordinary
course of business, except for obsolete items and items of below-standard quality, all of
which have been written-off or written-down to net realizable value on the Financial
Statements. All inventories not written-off have been priced at cost on a first-in, first
out basis. The quantities of each type of inventory, whether raw materials, work-in-process
or finished goods, are not excessive in the present circumstances of the Company and the
Subsidiaries.

     2.30 Accounts Receivable. All accounts receivable of the Company and the Subsidiaries reflected on the
Financial Statements are valid receivables subject to no setoffs or counterclaims and are
current and collectible (within ninety (90) days after the

16

 

date on which it first
became due and payable), net of the applicable reserve for bad debts on the Financial
Statements. All accounts receivable reflected in the financial or accounting records of the
Company that have arisen since March 31, 2007 are valid receivables subject to no setoffs or
counterclaims and are collectible (within ninety (90) days after the date on which it first
became due and payable), net of a reserve for bad debts in an amount proportionate to the
reserve shown on the Financial Statements.

     2.31 Product Warranty. No product manufactured, sold, leased, licensed or delivered by the Company or any
Subsidiary is subject to any guaranty, warranty, right of return, right of credit or other
indemnity other than (a) the applicable standard terms and conditions of sale or lease of
the Company or the appropriate Subsidiary, which are set forth in Section 2.31 of the
Schedule of Exceptions and (b) manufacturers’ warranties for which neither the Company nor
any Subsidiary has any liability. Section 2.31 of the Schedule of Exceptions sets forth the
aggregate expenses incurred by the Company and the Subsidiaries in fulfilling their
obligations under their guaranty, warranty, right of return and indemnity provisions during
each of the fiscal years and the interim period covered by the Financial Statements; and the
Company does not know of any reason why such expenses should significantly increase as a
percentage of sales in the future.

     2.32 Indebtedness. The Company has no Indebtedness other than the Notes and Senior Indebtedness. The
Company has provided to the Investors true and complete copies of all documents related to
any indebtedness of the Company.

     2.33 Margin Regulations. No part of the proceeds from the sale of the Notes will be used, directly or
indirectly, for the purpose of buying or carrying any margin stock within the meaning of
Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for
the purpose of buying or carrying or trading in any securities under such circumstances as
to involve the Company in a violation of Regulation X of said Board (12 CFR 224) or to
involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220).

     2.34 Investment Company. The Company is not subject to regulation under the Investment Company Act of 1940,
as amended.

     2.35 Disclosure. The Company has provided each Investor with all information that such Investor has
requested for deciding whether to purchase the Note. This Agreement, including all Exhibits
and Schedules hereto, and together with the written plans,
projections, and estimates provided to the Investors in connection with the
transactions contemplated by this Agreement (the “Additional Materials”), when read
together, do not contain any untrue statement of a material fact or omit a material fact
necessary in order to make the statements contained herein or therein, in the light of the
circumstances under which they were made, not misleading. The Company knows of no
information or fact which has or would have a Material Adverse Effect, which has not been
disclosed in the Schedule of Exceptions. Each projection furnished in the Additional
Materials was prepared in good faith based on reasonable assumptions and reflects the
Company’s best estimate of future results based on information available as of the date of
such Additional Materials.

     3. Representations and Warranties of the Investors. Each Investor, severally and not jointly, hereby represents and warrants that:

     3.1 Authorization. Such Investor has requisite corporate or partnership power and authority to enter
into this Agreement and the Ancillary Agreements, and each such agreement constitutes its
valid and legally binding obligation, enforceable in accordance with its terms except (a) as
limited by applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of
general application affecting enforcement of creditors’ rights generally, (b) as limited by
laws relating to the availability of specific performance, injunctive relief, or other
equitable remedies, and (c) to the extent the indemnification provisions contained in the
Investors’ Rights Agreement may be limited by applicable federal, state or provincial
securities laws.

     3.2 Purchase Entirely for Own Account. This Agreement is made with such Investor in reliance upon Investor’s representation
to the Company, which by such Investor’s execution of this Agreement such Investor hereby
confirms, that the Securities will be acquired for investment for Investor’s own account,
not as a nominee or agent, and not with a view to the distribution of any part thereof, and
that such Investor has no present intention of selling, granting any participation in, or
otherwise distributing the same. By executing this Agreement, such Investor further
represents that such Investor does not have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participations to such person or to
any third person, with respect to any of the Securities.

     3.3 Disclosure of Information. Such Investor further represents that it has had an opportunity to ask questions and
receive answers from the Company regarding the terms and conditions of the offering of the
Securities and the business, properties, prospects and financial condition of the Company.
The foregoing, however, does not limit or modify the representations and warranties of the
Company in Section 2 of this Agreement or the right of the Investor to rely thereon.

     3.4 Investment Experience. Such Investor is an investor in securities of companies in the development stage and
acknowledges that it is able to fend for itself, can bear the economic risk of its
investment, and has such knowledge and experience in financial or business matters that it
is capable of evaluating the merits and risks of the investment in the Securities. If other
than an individual, Investor also represents it has not been organized for the purpose of
acquiring the Securities.

     3.5 Accredited Investor. The Investor is an “accredited investor” within the meaning of Securities and
Exchange Commission (“SEC”) Rule 501 of Regulation D, as presently in effect and
understands the meaning of that term.

     3.6 Restricted Securities. Each Investor understands that the Securities have not been, and shall not be
(except to the extent provided in the Investors’ Rights Agreement), registered under the
Securities Act, by reason of a specific exemption from the registration provisions of the
Securities Act which depends upon, among other things, the bona fide nature of the
investment intent and the accuracy of the Investor’s

18

 

representations as expressed herein.
Each Investor understands that the Securities are “restricted securities” under applicable
U.S. federal and state securities laws and that, pursuant to these laws, the Investor must
hold the Securities indefinitely unless they are registered with the SEC and qualified by
state authorities, or an exemption from such registration and qualification requirements is
available. Each Investor acknowledges that the Company has no obligation to register or
qualify the Securities for resale except as set forth in the Investors’ Rights Agreement.
Each Investor further acknowledges that if an exemption from registration or qualification
is available, it may be conditioned on various requirements including, but not limited to,
the time and manner of sale, the holding period for the Securities, and on requirements
relating to the Company which are outside of the Investor’s control, and which the Company
is under no obligation (except to the extent provided in the Investors’ Rights Agreement)
and may not be able to satisfy.

     3.7 Further Limitations on Disposition. Without in any way limiting the representations set forth above, such Investor
further agrees not to make any disposition of all or any portion of the Securities to any
person or entity other than to an affiliate of such Investor unless and until:

     (a) There is then in effect a Registration Statement under the Act covering
such proposed disposition and such disposition is made in accordance with such
Registration Statement; or

     (b) Such Investor shall have (i) notified the Company of the proposed
disposition and (ii) if reasonably requested by the Company, such Investor shall
have furnished the Company with an opinion of counsel, that such disposition will
not require registration of such shares under the Act. It is agreed that the

reimburse each Indemnified Person for all reasonable expenses (including, but not limited
to, reasonable fees and disbursements of counsel) incurred by such Indemnified Person in
connection with investigating, preparing, responding to or defending any investigative,
administrative, judicial or regulatory action or proceeding in any jurisdiction related to
or arising out of such activities, services, transactions or role, whether or not in
connection with pending or threatened litigation to which any Indemnified Person is a party,
in each case as such expenses are incurred or paid; provided, that the foregoing
indemnification shall not, as to any Indemnified Person, apply to any such Liabilities or
expenses to the extent that they are finally judicially determined to have resulted
primarily from such Indemnified Person’s gross negligence or willful misconduct.

     6.10 Expenses. Each party shall pay its own costs and expenses incurred with respect to the
negotiation, execution, delivery and performance of this Agreement; provided, that the
Company shall, at the Closing, (a) reimburse the reasonable and actual out-of-pocket

with the transactions contemplated hereby, up to a total amount of $15,000.

     6.11 Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this
Agreement may be waived (either generally or in a

24

 

particular instance and either
retroactively or prospectively), only with the written consent of the Company and Investors
purchasing or holding at least a majority of the total indebtedness represented by the Notes
to be purchased or purchased hereunder. Any amendment or waiver effected in accordance with
this section shall be binding upon each holder of any securities purchased under this
Agreement at the time outstanding (including securities into which such securities are

the foregoing, no investment amount initially set forth on Schedule A may be changed without
the consent of such Investor.

     6.12 Severability. If one or more provisions of this Agreement are held to be unenforceable under
applicable law, such provision shall be excluded from this Agreement and the balance of the
Agreement shall be interpreted as if such provision were so excluded and shall be
enforceable in accordance with its terms.

     6.13 Entire Agreement. This Agreement and the documents referred to herein constitute the entire agreement
among the parties and no party shall be liable or bound to any other party in any manner by
any warranties, representations, or covenants except as specifically set forth herein or
therein.

     6.14 Delays or Omissions. No delay or omission to exercise any right, power, or remedy accruing to any party
upon any breach or default under this Agreement, shall be deemed a waiver of any other
breach or default theretofore or thereafter occurring. Any waiver, permit, consent, or
approval of any kind or character on the part of any party of any breach or default under
this Agreement, or any waiver on the part of any party of any provisions or conditions of
this Agreement, must be in writing and shall be effective only to the extent specifically
set forth in such writing. All remedies, either under this Agreement or by law or otherwise
afforded to any of the parties, shall be cumulative and not alternative.

     6.15 Public Announcements. Except for statements made or press releases (a) required to be issued pursuant to
the Securities Act of 1933 or the Securities Exchange Act of 1934, (b) required to be issued
pursuant to any listing agreement with or the rules and regulations of any national
securities exchange or automated quotation system on which the Company’s capital stock is
listed or quoted, or (c) otherwise required by law, no party shall issue any press release
or otherwise make any public statements with respect to this Agreement or the transactions
contemplated hereby without the prior written consent of the other parties. If the Company
is required to make any disclosure under applicable law that refers to GE or any of its
affiliates, the Company will provide prior written notice of such disclosure (together with
the proposed text of such disclosure) to GE, and the disclosure made by the Company will
reflect any comments provided to the Company by GE.

be deemed an original, but all of which together shall constitute one and the same
instrument. Facsimile signatures shall be binding as original.

     4. Subordination. The indebtedness evidenced by this Note is hereby expressly subordinated,
to the extent and in the manner hereinafter set forth, in right of payment to the prior payment in
full of all the Company’s Senior Indebtedness, as hereinafter defined.

     4.1 Senior Indebtedness. As used in this Note, the term “Senior Indebtedness” shall
mean the principal of and unpaid accrued interest on: (i) all existing indebtedness of the Company
to banks, commercial finance lenders, insurance companies or other financial institutions
regularly engaged in the business of lending money, which is for money borrowed by the Company
(whether or not secured); (ii) all indebtedness of the Company to banks, commercial finance
lenders, insurance companies, or other financial institutions regularly engaged in the business of
lending money, which may arise under any line of credit of the Company existing on the Original
Issue Date (whether or not secured); (iii) indebtedness pursuant to a capital lease with Wells
Fargo Equipment Finance, Inc. (or an affiliate) consistent with that certain lease proposal dated
July 25, 2007, a copy of which has been provided to Holder, and (iv) any such indebtedness or any
debentures, notes or other evidence of indebtedness issued in exchange for or to refinance such
Senior Indebtedness, or any indebtedness arising from the satisfaction of such Senior Indebtedness
by a guarantor.

     4.2 Default on Senior Indebtedness. If there should occur any receivership, insolvency,
assignment for the benefit of creditors, bankruptcy, reorganization or arrangements with creditors
(whether or not pursuant to bankruptcy or other insolvency laws), sale of all or substantially all
of the assets, dissolution, liquidation or any other marshalling of the assets and liabilities of
the Company then (i) no amount shall be paid by the Company in respect of the principal of or
interest on this Note at the time outstanding, unless and until the principal of and interest on
the Senior Indebtedness

5

 

then outstanding shall be satisfied, and (ii) no claim or proof of claim
shall be filed with the Company by or on behalf of the Holder of this Note that shall assert any
right to receive any payments in respect of the principal of and interest on this Note, except
subject to the satisfaction of the principal of and interest on all of the Senior Indebtedness
then outstanding. If there occurs an event of default that has been declared in writing with
respect to any Senior Indebtedness permitting the holder of such Senior Indebtedness to accelerate
the maturity thereof, then, unless and until such event of default shall have been cured or waived
or shall have ceased to exist, or all Senior Indebtedness shall have been satisfied, no payment
shall be made in respect of the principal of or interest on this Note.

     4.3 Effect of Subordination. Subject to the rights, if any, of the holders of Senior
Indebtedness under this Section 4 to receive cash, securities or other properties otherwise
payable or deliverable to the Holder of this Note, nothing contained in this Section 4 shall
impair, as between the Company and the Holder, the obligation of the Company, subject to the terms
and conditions hereof, to pay to the Holder the principal hereof and interest hereon as and when
the same become due and payable, or shall prevent the Holder of this Note, upon default hereunder,
from exercising all rights, powers and remedies otherwise provided herein or by applicable law.

     4.4 Undertaking. By its acceptance of this Note, the Holder agrees to execute and deliver
such documents as may be reasonably requested from time to time by the Company or the lender of any
Senior Indebtedness in order to implement the foregoing provisions of this Section 4, at the
expense of the Company.

     5. Prepayment. The Company shall not be permitted to prepay any outstanding principal under
this Note or interest thereon without Holder’s prior written consent.

     6. Conversion.

     6.1 Automatic Conversion. The principal and accrued interest outstanding under this Note
shall be converted, immediately, automatically and without election on the part of the Holder
hereof, upon the closing of a QIPO or a QExit into shares of the Company’s Common Stock at a
conversion price equal to $4.49 per share (the “Base Conversion Price”). For each quarter
in which interest accretes to the principal balance of this Note in accordance with Section
2.1(i)(A), the aggregate Base Conversion Price will increase by .975% of the original Base
Conversion Price (on a quarterly basis) in order to ensure that this Note shall at all times be convertible into an aggregate of
___shares of Common Stock (subject to anti-dilution adjustment as provided herein) (as
adjusted, the “Conversion Price”). In connection with a conversion effectuated pursuant to
this Section 6.1, the number of shares of Common Stock into which this Note may be converted shall
be determined by dividing the aggregate outstanding principal (including, for the avoidance of
doubt, any interest which has accreted to the principal balance as provided in Section 2.1(i)(A)
but excluding any cash payments of interest paid to Holder as provided in Section 2.1) through the
date of the conversion of the Note by the Conversion Price.

6

 

     6.2 Optional Conversion into Common Stock. At any time, all but not less than all of the
principal amount then outstanding under this Note (including, for the avoidance of doubt, any
interest which has accreted to the principal balance as provided in Section 2.1(i)(A) but excluding
any cash payments of interest paid to Holder as provided in Section 2.1) may, at the election of
the Holder, be converted into Common Stock of the Company, with such conversion to be effected at
the Conversion Price. The Holder shall exercise this optional conversion right, if at all, by
giving notice thereof to the Company at least ten (10) days prior to the date of conversion.

     6.3 Notice Regarding QIPO or QExit. At least ten (10) business days prior to the anticipated
closing of a QIPO or transaction which would constitute a QExit, written notice shall be delivered
to the Holder at the address last shown on the records of the Company for the Holder or given by
the Holder to the Company for the purpose of notice or, if no such address appears or is given, at
the place where the principal executive office of the Company is located, (1) notifying the Holder
of the QIPO or QExit, (2) specifying (A) in the case of a QExit, the terms and conditions thereof,
(B) the then outstanding principal amount of the Note, (C) the then outstanding amount of accreted
interest as provided for in Section 2.1(i)(A), and (D) the date on which such transaction will
close (which in no event shall be less than ten (10) business days following delivery of said
notice), and, (3) if the Note is subject to automatic conversion pursuant to Section 6.1, calling
upon such Holder to surrender the Note to the Company in the manner and at the place designated in
such notice.

     6.4 Mechanics and Effect of Conversion. No fractional shares of Common Stock shall be issued
upon conversion of this Note. In lieu of the Company issuing any fractional shares to the Holder
upon the conversion of this Note, the Company shall pay to the Holder the amount outstanding that
is not so converted, such payment to be in made by Company check in an amount equal to the
fractional share multiplied by the Conversion Price. At its expense, the Company shall, as soon as
practicable following conversion of this Note and surrender of this Note to the Company, issue and
deliver to the Holder at its principal office a certificate or certificates for the number of
shares of Common Stock to which the Holder shall be entitled upon such conversion (bearing such
legends as are required by any applicable purchase documents and applicable state and federal
securities laws in the opinion of counsel to the Company), together with any other securities and
property to which the Holder is entitled upon such conversion under the terms of this Note,
including a check payable to the Holder for any cash amounts payable as described above. Upon conversion of this Note, the Company shall be forever released from
all its obligations and liabilities under this Note, except that the Company shall be obligated to
pay the Holder, within ten (10) days after the date of such conversion, the cash equivalent of any
fractional shares that otherwise would have been issued upon such conversion, and no more.

     6.5 Reservation of Stock Issuable Upon Conversion. The Company covenants and agrees that the
Company shall reserve a sufficient number of shares of Common Stock to comply with the conversion
provisions contained herein with respect to an amount equal to the principal outstanding under this
Note and the accrued interest thereon.

7

 

     7. Adjustments to Conversion Price for Diluting Issues.

     7.1 Special Definitions. For purposes of this Section 7, the following definitions shall
apply:

     (i) “Option” shall mean rights, options or warrants to subscribe for, purchase
or otherwise acquire Common Stock or Convertible Securities.

     (ii) “Convertible Securities” shall mean any evidences of indebtedness, shares
or other securities directly or indirectly convertible into or exchangeable for Common
Stock, but excluding Options.

     (iii) “Additional Shares of Common Stock” shall mean all shares of Common
Stock issued (or, pursuant to Section 7.3 below, deemed to be issued) by the Company after
the Original Issue Date, other than the following (“Exempted Securities”):

      (1) shares of Common Stock issued or deemed issued as a dividend or
distribution on, or upon conversion of, the shares of Series B Preferred Stock or
Series C Preferred Stock outstanding on the Original Issue Date, or the Notes;

      (2) shares of Common Stock issued upon exercise or conversion of any Options
or Convertible Securities outstanding on the Original Issue Date;

      (3) shares of Common Stock issued or issuable by reason of a dividend, stock
split, split-up or other distribution on shares of Common Stock that is covered by
Section 7.7(i) or (ii);

      (4) up to an aggregate total of 100,000 shares of Common Stock or warrants to
purchase Common Stock issued pursuant to any strategic partnership, in each case
approved by a majority of the Independent Directors; or

      (5) shares of Common Stock issued or issuable pursuant to Options authorized
under existing stock option plans in effect as of the Original Issue Date, provided
that any new grants under such existing stock option plans must be approved by the
Independent Directors.

     7.2 No Adjustment of Conversion Price. No adjustment in the Conversion Price shall be made as
the result the issuance of Additional Shares of Common Stock if: (i) the consideration per share
(determined pursuant to Section 7.5) for such Additional Share of Common Stock issued or deemed to
be issued by the Company is equal to or greater than the Conversion Price in effect immediately
prior to the issuance or deemed issuance of such Additional Shares of Common Stock, or (ii) prior
to such issuance or deemed issuance, the Company receives written notice from the holders of Notes
constituting a majority of the total indebtedness represented by the Notes, voting as a

8

 

single class and on an as-converted to Common Stock basis, agreeing that no such adjustment shall be made
as the result of the issuance or deemed issuance of such Additional Shares of Common Stock.

     7.3 Issue of Securities Deemed Issue of Additional Shares of Common Stock.

     (i) If the Company at any time or from time to time after the Original Issue Date
shall issue any Options or Convertible Securities (excluding Options or Convertible
Securities which, upon exercise, conversion or exchange thereof, would entitle the holder
thereof to receive Exempted Securities) or shall fix a record date for the determination of
holders of any class of securities entitled to receive any such Options or Convertible
Securities, then the maximum number of shares of Common Stock (as set forth in the
instrument relating thereto without regard to any provision contained therein for a
subsequent adjustment of such number) issuable upon the exercise of such Options or, in the
case of Convertible Securities and Options therefor, the conversion or exchange of such
Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as
of the time of such issue or, in case such a record date shall have been fixed, as of the
close of business on such record date.

     (ii) If the terms of any Option or Convertible Security, the issuance of which
resulted in an adjustment to the Conversion Price, as the case may be, pursuant to the
terms of Section 7.4 below, are revised (either automatically pursuant to the provisions
contained therein or as a result of an amendment to such terms) to provide for either (A)
any increase or decrease in the number of shares of Common Stock issuable upon the
exercise, conversion or exchange of any such Option or Convertible Security or (B) any
increase or decrease in the consideration payable to the Company upon such exercise,
conversion or exchange, then, effective upon such increase or decrease becoming effective,
the Conversion Price computed upon the original issue of such Option or Convertible
Security (or upon the occurrence of a record date with respect thereto) shall be readjusted
to such Conversion Price as would have obtained had such revised terms been in effect upon
the original date of issuance of such Option or Convertible Security. Notwithstanding the foregoing, no adjustment pursuant
to this clause (ii) shall have the effect of increasing the Conversion Price to an amount
which exceeds the lower of (1) the Conversion Price on the original adjustment date, or (2)
the Conversion Price that would have resulted from any issuances of Additional Shares of
Common Stock between the original adjustment date and such readjustment date.

     (iii) If the terms of any Option or Convertible Security (excluding Options or
Convertible Securities which, upon exercise, conversion or exchange thereof, would entitle
the holder thereof to receive Exempted Securities), the issuance of which did not result in
an adjustment to the Conversion Price pursuant to the terms of Section 7.4 below (either
because the consideration per share (determined pursuant to Section 7.5 hereof) of the
Additional Shares of Common Stock subject thereto was equal to or greater than the
Conversion Price then in

9

 

effect, or because such Option or Convertible Security was issued
before the Original Issue Date), are revised after the Original Issue Date (either
automatically pursuant to the provisions contained therein or as a result of an amendment
to such terms) to provide for either (1) any increase or decrease in the number of shares
of Common Stock issuable upon the exercise, conversion or exchange of any such Option or
Convertible Security or (2) any increase or decrease in the consideration payable to the
Company upon such exercise, conversion or exchange, then such Option or Convertible
Security, as so amended, and the Additional Shares of Common Stock subject thereto
(determined in the manner provided in Section 7.3(i) above) shall be deemed to have been
issued effective upon such increase or decrease becoming effective.

     (iv) Upon the expiration or termination of any unexercised Option or unconverted or
unexchanged Convertible Security which resulted (either upon its original issuance or upon
a revision of its terms) in an adjustment to the Conversion Price pursuant to the terms of
Section 7.4 below, the Conversion Price shall be readjusted to such Conversion Price as
would have obtained had such Option or Convertible Security never been issued.

     (v) No adjustment in the Conversion Price shall be made upon the issue of shares of
Common Stock or Convertible Securities upon the exercise of Options or the issue of shares
of Common Stock upon the conversion or exchange of Convertible Securities.

     7.4 Adjustment of Conversion Price Upon Issuance of Additional Shares of Common Stock. In the
event the Company shall at any time after the Original Issue Date issue Additional Shares of Common
Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Section 7.3),
without consideration or for a consideration per share less than the Conversion Price in effect
immediately prior to such issue, then the Conversion Price shall be reduced, concurrently with such
issue, to a price (calculated to the nearest one-hundredth of a cent) determined by multiplying the Conversion Price by a fraction, (a) the numerator of which shall be (i) the
number of shares of Common Stock outstanding immediately prior to such issue plus (ii) the number
of shares of Common Stock which the aggregate consideration received or to be received by the
Company for the total number of Additional Shares of Common Stock so issued would purchase at the
Conversion Price and (b) the denominator of which shall be (i) the number of shares of Common Stock
outstanding immediately prior to such issue plus (ii) the number of such Additional Shares of
Common Stock so issued; provided that, for the purpose of this Section 7.4, all shares of Common
Stock issuable upon exercise of Options outstanding immediately prior to such issue or upon
conversion of Convertible Securities (including the Series C Preferred Stock and the shares into
which this Note may be converted) outstanding immediately prior to such issue shall be deemed to be
outstanding.

     7.5 Determination of Consideration. For purposes of this Section 7, the consideration
received by the Company for the issue of any Additional Shares of Common Stock shall be computed as
follows:

10

 

     (i) Cash and Property. Such consideration shall:

     (1) insofar as it consists of cash, be computed at the aggregate amount of
cash received by the Company, excluding amounts paid or payable for accrued
interest;

     (2) insofar as it consists of property other than cash, be computed at the
fair market value thereof at the time of such issue, as determined in good faith by
the Board of Directors of the Company; and

     (3) in the event Additional Shares of Common Stock are issued together with
other shares or securities or other assets of the Company for consideration which
covers both, be the proportion of such consideration so received, computed as
provided in clauses (1) and (2) above, as determined in good faith by the Board of
Directors of the Company.

     (ii) Options and Convertible Securities. The consideration per share received
by the Company for Additional Shares of Common Stock deemed to have been issued pursuant to
Section 7.3, relating to Options and Convertible Securities, shall be determined by
dividing the total amount, if any, received or receivable by the Company as consideration
for the issue of such Options or Convertible Securities, plus the minimum aggregate amount
of additional consideration (as set forth in the instruments relating thereto, without
regard to any provision contained therein for a subsequent adjustment of such
consideration) payable to the Company upon the exercise of such Options or the conversion
or exchange of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the conversion or
exchange of such Convertible Securities, by the maximum number of shares of Common Stock (as set forth
in the instruments relating thereto, without regard to any provision contained therein for
a subsequent adjustment of such number) issuable upon the exercise of such Options or the
conversion or exchange of such Convertible Securities.

     7.6 Multiple Closing Dates. In the event the Company shall issue on more than one date
Additional Shares of Common Stock that are comprised of shares of the same series or class of
Preferred Stock and that would result in an adjustment to Conversion Price pursuant to the terms of
Section 7.4 above, and such issuance dates occur within a period of no more than forty-five (45)
days from the first such issuance to the final such issuance, then, upon the final such issuance,
the Conversion Price shall be readjusted to give effect to all such issuances as if they occurred
on the date of the final such issuance (and without giving effect to any adjustments as a result of
such prior issuances within such period).

     7.7 Adjustments.

     (i) Adjustment for Stock Splits and Combinations. If the Company shall at any
time or from time to time after the Original Issue Date effect a

11

 

subdivision of the outstanding Common Stock, the Conversion Price in effect immediately before that
subdivision or combination shall be proportionately decreased. If the Company shall at any
time or from time to time after the Original Issue Date combine the outstanding shares of
Common Stock, the Conversion Price in effect immediately before the combination or
subdivision shall be proportionately increased. Any adjustment under this paragraph shall
become effective at the close of business on the date the subdivision or combination
becomes effective.

     (ii) Adjustment for Certain Dividends and Distributions. In the event the
Company at any time, or from time to time after the Original Issue Date shall make or
issue, or fix a record date for the determination of holders of Common Stock entitled to
receive, a dividend or other distribution payable in additional shares of Common Stock,
then and in each such event the Conversion Price in effect immediately before such event
shall be decreased as of the time of such issuance or, in the event such a record date
shall have been fixed, as of the close of business on such record date, by multiplying the
Conversion Price, as the case may be, then in effect by a fraction:

     (1) the numerator of which shall be the total number of shares of Common Stock
issued and outstanding immediately prior to the time of such issuance or the close
of business on such record date, and

     (2) the denominator of which shall be the total number of shares of Common
Stock issued and outstanding immediately prior to the time of such issuance or the
close of business on such record date plus the number of shares of Common Stock
issuable in payment of such dividend or distribution; provided, however, that if such record date
shall have been fixed and such dividend is not fully paid or if such distribution
is not fully made on the date fixed therefor, the Conversion Price shall be
recomputed accordingly as of the close of business on such record date and
thereafter the Conversion Price shall be adjusted pursuant to this paragraph as of
the time of actual payment of such dividends or distributions; and provided
further, however, that no such adjustment shall be made if the
holders of the Note simultaneously receive a dividend or other distribution of
            shares of Common Stock in a number equal to the number of shares of Common Stock as
they would have received if the outstanding balance of this Note had been converted
into Common Stock on the date of such event.

     (iii) Adjustments for Other Dividends and Distributions. In the event the
Company at any time or from time to time after the Original Issue Date shall make or issue,
or fix a record date for the determination of holders of Common Stock entitled to receive,
a dividend or other distribution payable in securities of the Company (other than shares of
Common Stock) or in cash or other property, then and in each such event the holders of the
Note shall receive, simultaneously with the distribution to the holders of Common Stock, a
dividend or other distribution of such securities, cash or other property in an amount
equal to the

12

 

amount of such securities, cash or other property as they would have received
if the outstanding balance of the Note had been converted into Common Stock on the date of
such event.

     7.8 Certificate as to Adjustments. Upon the occurrence of each adjustment or
readjustment of the Conversion Price pursuant to Section 7.7, the Company at its expense shall, as
promptly as reasonably practicable but in any event not later than thirty (30) days thereafter,
compute such adjustment or readjustment in accordance with the terms hereof and furnish to each

parties.

     10. Waiver and Amendment. Any provision of this Note may be amended, waived or modified upon
the written consent of the Company and the holders of a majority in interest of the Notes;
provided, however, that the approval of all holders of any portion of the Notes will be required to
change the amount or time of any prepayment or payment of principal of the Notes, reduce the rate
or change the time of payment or method of computation of interest or premium of the Notes and
provided, further, the consent of an affected Holder shall be required to modify or otherwise

15

 

     11. Transfer of this Note. This Note or any Common Stock into which this Note is convertible
(collectively, the “Securities”) may not be transferred except as provided herein. At any
time beginning two years after the issuance of the Note, Holder will have the right to transfer the
Securities as long as (i) the transfer is not in violation of any law, (ii) the Securities are not
transferred to a competitor of the Company (if a majority of the Independent Directors determines
in good faith that the proposed transferee is a competitor of the Company and that such proposed
transfer would not be in the best interests of the Company, such consent to transfer not to be
unreasonably withheld), (iii) the transfer is after a right of first offer to the Company (if the
Company would have a right of first refusal with respect to such transfer under Section 3 of the

Documents. Without limiting the foregoing, this Note may not be transferred in violation of any
restrictive legend set forth hereon at any time. Notwithstanding the foregoing, Holder may, at any
time upon written notice to the Company, transfer any or all of the Securities to an affiliate
without being subject to the foregoing restrictions. All such restrictions on Holder’s right of
transfer shall terminate following an initial public offering or other registration of Company
shares or a Change of Control. Each new note issued upon transfer of this Note 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 the Company such legend is not required in
order to ensure compliance with the Act. The 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 the Company. Prior to
presentation of this Note for registration of transfer, the 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 the Company shall not be affected by notice to the contrary.

     12. Assignment by the Company. Neither this Note nor any of the rights, interests or
obligations hereunder may be assigned in whole or in part by the Company without the prior written
consent of the Holder.

     13. Treatment of Note. To the extent permitted by generally accepted accounting principles,
the Company will treat, account and report the Note as debt and not equity for accounting purposes
and with respect to any returns filed with federal, state or local tax authorities.

     14. Notices. Any notice, request or other communication required or permitted hereunder shall
be in writing and shall be deemed to have been duly given if personally delivered, if faxed with
confirmation of receipt, or if mailed by registered or certified mail or reputable overnight
courier, postage prepaid, at the respective addresses of the parties as set forth herein and in the
case of the Holder to the attention of ___and in the case of the Company to the
attention of the Chief Executive Officer. Any party hereto may by notice so given change its
address for future notice hereunder. Notice shall conclusively be deemed to have been given when
personally

16

 

delivered, faxed, or when deposited in the mail in the manner set forth above and shall
be deemed to have been received when delivered.

     15. Confidentiality. The Holder agrees that such Holder will keep confidential and will not
disclose, divulge or use for any purpose, other than to monitor its investment in the Company, any
confidential information obtained from the Company pursuant to the terms of this Note, unless such
confidential information (i) is known or becomes known to the public in general (other than as a
result of a breach of this Section 15 by the Holder), (ii) is or has been independently developed
or conceived by the Holder without use of the Company’s confidential information or (iii) is or has
been made known or disclosed to the Holder by a third party without a breach of any obligation of
confidentiality such third party may have to the Company; provided, however, that the Holder may
disclose confidential information (1) to its attorneys, accountants, consultants, and other
professionals to the extent necessary to obtain their services in connection with monitoring its
investment in the Company, or (2) as may otherwise be required by law or by the rules and
regulations of any exchange or automated quotation system on which the Company’s capital stock is
listed or quoted, provided that the Holder takes reasonable steps to minimize the extent of any
such required disclosure.

     16. Disclosure. The Company shall have the right to disclose the Holder’s investment in the
Company to future prospective investors and/or strategic partners contemplating an investment in the Company, provided, that such recipient is subject to a
non-disclosure agreement; provided, that the Company will provide prior written notice of such
disclosure (together with the proposed text of such disclosure) to the Holder, and the disclosure
made by the Company will reflect any comments provided to the Company by the Holder.
Notwithstanding the foregoing, but subject to the requirement above to provide prior written notice
of such disclosure as provided above, this Section 16 shall not prohibit any disclosure required by
law or by the rules and regulations of any exchange or automated quotation system on which the
Company’s capital stock is listed or quoted.

     17. Governing Law. This Agreement shall be governed by and construed in accordance with the
laws of the State of New York, excluding that body of law relating to conflict of laws.

Company issued as (or issuable upon the conversion or exercise of any warrant, right or other

or in replacement of, the shares referenced in (i) and (ii) above, excluding in all cases, however,
any Registrable Securities sold by a person in a transaction in which his rights under this Section
1 are not assigned.

          (j) The number of shares of “Registrable Securities” outstanding shall be determined by the

          (l) The term “Rule 144” shall mean Rule 144 under the Act.

2

 

receivers in bankruptcy
proceedings or general assignees for the benefit of creditors, whether voluntary, involuntarily or
by operation of law, directly or indirectly, of any of the Registrable Securities.

     1.2 Request for Registration.

          (a) Subject to the conditions of this Section 1.2, if the Company shall receive at any time
beginning six (6) months after the effective date of the first underwritten public offering by the
Company pursuant to a registration statement filed with the SEC under the Act, a written request
from the Holders (for purposes of this Section 1.2, the “Initiating Holders”) that the Company file
a registration statement under the Act covering the registration of Registrable Securities with an
anticipated aggregate offering price of at least five million dollars ($5,000,000), then the
Company shall, within twenty (20) days of the receipt thereof, give written notice of such request
to all Holders, and subject to the limitations of this Section 1.2, use all commercially reasonable
efforts to effect, as soon as practicable, the registration under the Act of all Registrable
Securities that the Holders request to be registered in a written request received by the Company
within twenty (20) days of the mailing of the Company’s notice pursuant to this Section 1.2(a).

          (b) If the Initiating Holders intend to distribute the Registrable Securities covered by their
request by means of an underwriting, they shall so advise the Company as a part of their request
made pursuant to this Section 1.2 and the Company shall include such information in the written
notice referred to in Section 1.2(a). In such event the right of any Holder to include its
Registrable Securities in such registration shall be conditioned upon such Holder’s participation
in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting
(unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such
Holder) to the extent provided herein. All Holders proposing to distribute their securities
through such underwriting shall enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting by the Company (which underwriter or
underwriters shall be reasonably acceptable to a majority in interest of the Initiating Holders).
Notwithstanding any other provision of this Section 1.2, if the underwriter advises the Company
that marketing factors require a limitation on the number of securities underwritten (including
Registrable Securities), then the Company shall so advise all Holders of Registrable Securities
that would otherwise be underwritten pursuant hereto, and the number of shares that may be included
in the underwriting shall be allocated (i) first, to Requesting Holders of Registrable Securities
who hold (or held) Series C Preferred Stock or the Notes, as the case may be, and which made the
request for registration under this Section 1.2, pro rata according to the number of shares of
Series C Preferred Stock or Common Stock issued or issuable upon conversion of the Notes held by
each such Holder; (ii) second, to Holders of Registrable Securities who hold (or held) shares of
the series of Series C Preferred Stock or Common Stock issued or issuable upon conversion of the
Notes which did not make the request for registration under this Section 1.2, pro rata according to
the number of shares of such equity
securities held by such Holder; (iii) third, to the remaining Holders of Registrable
Securities pro rata based on the number of Registrable Securities held by all such Holders; and
(iv) fourth, to the Company. In no event shall any Registrable Securities be excluded from such
underwriting

3

 

unless all other securities are first excluded. Any Registrable Securities excluded
or withdrawn from such underwriting shall be withdrawn from the registration.

          (c) Notwithstanding the foregoing, the Company shall not be required to effect a registration
pursuant to this Section 1.2:

               (i) in any particular jurisdiction in which the Company would be required to execute a general
consent to service of process in effecting such registration, unless the Company is already subject
to service in such jurisdiction and except as may be required under the Act;

               (ii) after the Company has effected pursuant to this Section 1.2 (A) two (2) registrations
requested by the Holders of the Series C Preferred Stock or the Common Stock issued upon the
conversion thereof, and (B) two (2) registrations requested by GE Capital Equity Investments, Inc.
(“GE”), and such registrations have been declared or ordered effective;

               (iii) during the period starting with the date sixty (60) days prior to the Company’s good
faith estimate of the date of the filing of and ending on a date one hundred eighty (180) days
following the effective date of a Company initiated registration subject to Section 1.3 below,
provided that the Company is actively employing in good faith all commercially reasonable efforts
to cause such registration statement to become effective;

               (iv) if the Initiating Holders propose to dispose of Registrable Securities that may be
registered on Form S-3 pursuant to Section 1.4 hereof; or

               (v) if the Company furnishes to Holders requesting a registration statement pursuant to this
Section 1.2 a certificate signed by the Company’s Chief Executive Officer or Chairman of the Board
stating that in the good faith judgment of the Board of Directors of the Company (the “Board”), it
would be seriously detrimental to the Company and its shareholders for such registration statement
to be effected at such time, in which event the Company shall have the right to defer such filing
for a period of not more than one hundred twenty (120) days after receipt of the request of the
Initiating Holders, provided that such right shall be exercised by the Company not more than once
in any twelve (12) month period and provided further that the Company shall not register any
securities for the account of itself or any other shareholder during such one hundred twenty (120)
day period (other than a registration relating solely to the sale of securities of participants in
a Company stock plan, a registration relating to a corporate reorganization or transaction under
Rule 145 of the Act, a registration on any form that does not include substantially the same
information as would be required to be included in a registration statement covering the sale of
the Registrable Securities, or a registration in which the only Common Stock being registered is
Common Stock issuable upon conversion of debt securities that are also being registered).

     1.3 Company Registration.

4

 

          (a) If, at any time beginning six (6) months after the effective date of this Agreement (such
six (6) month period being referred to as the “Restricted Period”), the Company proposes to
register (including for this purpose a registration effected by the Company for shareholders other
than the Holders) any of its stock or other securities under the Act in connection with the public
offering of such securities (other than a registration relating solely to the sale of securities of
participants in a Company stock plan, a registration relating to a corporate reorganization or
transaction under Rule 145 of the Act, a registration on any form that does not include
substantially the same information as would be required to be included in a registration statement
covering the sale of the Registrable Securities, or a registration in which the only Common Stock
being registered is Common Stock issuable upon conversion of debt securities that are also being
registered), the Company shall, at such time, promptly give each Holder written notice of such
registration. Upon the written request of each Holder given within twenty (20) days after mailing
of such notice by the Company in accordance with Section 4.5, the Company shall, subject to the
provisions of Section 1.3(c), use all commercially reasonable efforts to cause to be registered
under the Act all of the Registrable Securities that each such Holder requests to be registered.
Notwithstanding the prohibition on exercising registration rights during the Restricted Period set
forth in the first sentence of this Section 1.3(a), (i) CapVest Venture Fund, LP and Technology
Transformation Venture Fund, LP may exercise such registration rights for up to one hundred twelve
thousand one hundred nine (112,109) shares of their Registrable Securities; (ii) Clean Technology
Fund II, LP may exercise such registration rights for up to one million nine thousand ninety one
(1,009,091) shares of its Registrable Securities (the shares referenced in (i) and (ii) being
referred to as the “Series C Threshold Amount”); and (iii) in the event that in any
registration within the Restricted Period any senior management employee of the Company or director
of the Company who is an employee of the Company and who is listed on Exhibit A, as long as
such person is employed by the Company (the “Senior Management Employees” and “Director Employees”)
registers more than fifteen percent (15%), on a fully diluted basis, of the number of shares held
by such Senior Management Employee or Director Employee (such figure being referred to herein as
the “Threshold Senior Management Registrable Securities”), then all of the Investors shall be
entitled to exercise such registration rights for all or any portion of their Registrable
Securities.

          (b) Right to Terminate Registration. The Company shall have the right to terminate or
withdraw any registration initiated by it under this Section 1.3 prior to the effectiveness of such
registration whether or not any Holder has elected to include securities in such registration. The
expenses of such withdrawn registration shall be borne by the Company in accordance with Section
1.7 hereof.

          (c) Underwriting Requirements. In connection with any offering involving an
underwriting of shares of the Company’s capital stock, the Company shall not be required under this
Section 1.3 to include any of the Holders’ securities in such underwriting unless they accept the
terms of the underwriting as agreed upon between the Company and the underwriters selected by the
Company (or by other persons entitled to select the underwriters) and enter into an underwriting
agreement in customary form with such underwriters, and then only in such quantity as the
underwriters determine in their sole discretion will not jeopardize the
success of the offering by the Company. If the total amount of securities, including
Registrable Securities, requested by shareholders to be included in such offering exceeds the
amount of

5

 

securities sold other than by the Company that the underwriters determine in their sole
discretion is compatible with the success of the offering, then the Company shall be required to
include in the offering only that number of such securities, including Registrable Securities, that
the underwriters determine in their sole discretion will not jeopardize the success of the
offering. In no event shall any Registrable Securities be excluded from such offering unless all
other shareholders’ securities have been first excluded. In the event that the underwriters
determine that less than all of the Registrable Securities requested to be registered after the
expiration of Restricted Period can be included in such offering, then the Registrable Securities
that are included in such offering shall be allocated (i) first, to Holders of Registrable
Securities who hold (or held) Notes or Series C Preferred Stock, pro rata according to the number
of Registrable Securities held by each such Holder; and (ii) second, to the remaining Holders of
Registrable Securities pro rata based on the number of Registrable Securities held by all such
Holders. In the event that the underwriters determine that less than all of the Registrable
Securities requested to be registered before the expiration of the Restricted Period can be
included in such offering, then the Registrable Securities that are included in such offering shall
be allocated (i) first, to Holders of Registrable Securities who hold (or held) Series C Preferred
Stock, pro rata according to the number of Registrable Securities held by each such Holder, up to
the Series C Threshold Amount; and (ii) second, after the Senior Management Employees and Director
Employees have each registered up to their Threshold Senior Management Registrable Securities, to
all Holders of Registrable Securities, pro rata according to the number of Registrable Securities
held by each such Holder of Registrable Securities held by all such Holders. Notwithstanding the
foregoing, in no event shall (i) the amount of securities of the selling Holders included in the
offering be reduced below thirty percent (30%) of the total amount of securities included in such
offering, unless such offering is the Company’s first firm commitment underwritten public offering
of its Common Stock under the Act (the “Initial Offering”), in which case the selling Holders may
be excluded if the underwriters make the determination described above and no other shareholder’s
securities are included in such offering. For purposes of the preceding sentence and for purposes
of Section 1.2(b) concerning apportionment, for any selling shareholder that is a Holder of
Registrable Securities and that is a venture capital fund, partnership or corporation, the
affiliated venture capital funds, partners, retired partners and shareholders of such Holder, or
the estates and family members of any such partners and retired partners and any trusts for the
benefit of any of the foregoing persons shall be deemed to be a single “selling Holder,” and any
pro rata reduction with respect to such “selling Holder” shall be based upon the aggregate amount
of Registrable Securities owned by all such related entities and individuals.

     1.4 Form S-3 Registration. In case the Company shall receive from the Holders of twenty-five
percent (25%) or more of the Registrable Securities then outstanding (for purposes of this Section
1.4, the “Initiating Holders”) a written request or requests that the Company effect a registration
on Form S-3 and any related qualification or compliance with respect to all or a part of the
Registrable Securities owned by such Holder or Holders, the Company shall:

          (a) promptly give written notice of the proposed registration, and any related qualification
or compliance, to all other Holders; and

6

 

          (b) use all commercially reasonable efforts to effect, as soon as practicable, such
registration and all such qualifications and compliances as may be so requested and as would permit
or facilitate the sale and distribution of all or such portion of such Holders’ Registrable
Securities as are specified in such request, together with all or such portion of the Registrable
Securities of any other Holders joining in such request as are specified in a written request given
within fifteen (15) days after receipt of such written notice from the Company, provided, however,
that the Company shall not be obligated to effect any such registration, qualification or
compliance, pursuant to this Section 1.4:

               (i) if Form S-3 is not available for such offering by the Holders;

               (ii) if the Company furnishes to Holders requesting a registration statement pursuant to this
Section 1.4 a certificate signed by the Company’s Chief Executive Officer or Chairman of the Board
stating that in the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such registration statement to be
effected at such time, in which event the Company shall have the right to defer such filing for a
period of not more than one hundred twenty (120) days after receipt of the request of the
Initiating Holders, provided that such right shall be exercised by the Company not more than once
in any twelve (12)-month period and provided further that the Company shall not register any
securities for the account of itself or any other shareholder during such one hundred twenty (120)
day period (other than a registration relating solely to the sale of securities of participants in
a Company stock plan, a registration relating to a corporate reorganization or transaction under
Rule 145 of the Act, a registration on any form that does not include substantially the same
information as would be required to be included in a registration statement covering the sale of
the Registrable Securities, or a registration in which the only Common Stock being registered is
Common Stock issuable upon conversion of debt securities other than the Note that are also being
registered); or

               (iii) in any particular jurisdiction in which the Company would be required to qualify to do
business or to execute a general consent to service of process in effecting such registration,
qualification or compliance.

          (c) If the Initiating Holders intend to distribute the Registrable Securities covered by their
request by means of an underwriting, they shall so advise the Company as a part of their request
made pursuant to this Section 1.4 and the Company shall include such information in the written
notice referred to in Section 1.4(a). The provisions of Section 1.2(b) shall be applicable to such
request (with the substitution of Section 1.4 for references to Section 1.2).

          (d) Subject to the foregoing, the Company shall file a registration statement covering the
Registrable Securities and other securities so requested to be registered as soon as practicable
after receipt of the request or requests of the Initiating Holders. Registrations
effected pursuant to this Section 1.4 shall not be counted as requests for registration
effected pursuant to Section 1.2 and thus not subject to the limitations found in Section
1.2(c)(ii).

7

 

     1.5 Obligations of the Company. Whenever required under this Section 1 to effect the registration
of any Registrable Securities, the Company shall, as expeditiously as reasonably possible:

          (a) prepare and file with the SEC a registration statement with respect to such Registrable
Securities and use all commercially reasonable efforts to cause such registration statement to
become effective, and, upon the request of the Holders of a majority of the Registrable Securities
registered thereunder, keep such registration statement effective for a period of up to one hundred
twenty (120) days or, if earlier, until the distribution contemplated in the Registration Statement
has been completed; provided, however, that such 120 day period shall be extended for a period of
time equal to the period of time that the Holders refrain from selling any securities included in
such registration upon the request of the Company or the underwriters;

          (b) prepare and file with the SEC such amendments and supplements to such registration
statement and the prospectus used in connection with such registration statement as may be
necessary to comply with the provisions of the Act with respect to the disposition of all
securities covered by such registration statement;

          (c) furnish to the Holders such number of copies of a prospectus, including a preliminary
prospectus, in conformity with the requirements of the Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable Securities owned by them;

          (d) use all commercially reasonable efforts to register and qualify the securities covered by
such registration statement under such other securities or Blue Sky laws of such jurisdictions as
shall be reasonably requested by the Holders, provided that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to file a general
consent to service of process in any such states or jurisdictions;

          (e) in the event of any underwritten public offering, enter into and perform its obligations
under an underwriting agreement, in usual and customary form, with the managing underwriter of such
offering; and furnish, at the request of any Holder requesting registration of Registrable
Securities pursuant to this Section 1, on the date that such Registrable Securities are delivered
to the underwriters for sale in connection with a registration pursuant to this Section 1, if such
securities are being sold through underwriters, (i) an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, in form and substance as is
customarily given to underwriters in an underwritten public offering, addressed to the underwriters
and (ii) a letter dated such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified accountants to
underwriters in an underwritten public offering, addressed to the underwriters;

          (f) notify each Holder of Registrable Securities covered by such registration statement at any
time when a prospectus relating thereto is required to be delivered under the Act of the happening
of any event as a result of which the prospectus included in such

8

 

registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing, and the Company shall promptly either amend such
prospectus or file a supplement, in compliance with state and federal securities laws, to correct
such untrue statement of material fact or omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light of the
circumstances then existing;

          (g) cause all such Registrable Securities registered pursuant to this Section 1 to be listed
on a national exchange or trading system and on each securities exchange and trading system on
which similar securities issued by the Company are then listed;

          (h) provide a transfer agent and registrar for all Registrable Securities registered pursuant
hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the
effective date of such registration;

          (i) notify each Holder promptly after the Company receives notice thereof, of the time when
such registration statement has become effective or a supplement of such registration has been
filed;

          (j) advise each Holder promptly after the Company shall receive notice or obtain knowledge
thereof, of the issuance of any stop order by the SEC suspending the effectiveness of such
registration statement or the threatening of any proceeding for such purpose and promptly use all
commercially reasonable efforts to prevent the issuance of any stop order should such be issued;
and

          (k) make generally available to its security holders, and to deliver to the Holders an
earnings statement of the Company (that will satisfy the provisions of Section 11(a) of the Act)
covering a period of twelve (12) months beginning after the effective date of the registration
statement (as defined in Rule 158(c) under the Act) as soon as is reasonably practicable after the
termination of such twelve (12) month period and upon the request of a Holder.

     1.6 Information from Holder. It shall be a condition precedent to the obligations of the Company
to take any action pursuant to this Section 1 with respect to the Registrable Securities of any
selling Holder that such Holder shall furnish to the Company such information regarding itself, the
Registrable Securities held by it, and the intended method of disposition of such securities as
shall be reasonably required to effect the registration of such Holder’s Registrable Securities.

     1.7 Expenses of Registration. All expenses other than underwriting discounts and commissions (which shall be borne by the
selling Holders pro rata based on the number of Registrable Securities included in the
registration) incurred in connection with registrations, filings or qualifications pursuant to
Sections 1.2, 1.3 and 1.4, including (without limitation) all registration, filing and
qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the
Company and the reasonable fees and disbursements of one counsel for the

9

 

selling Holders shall be
borne by the Company. In the event the Holders of the Series C Preferred Stock elect to retain
separate counsel to represent them in connection with registrations, filings or qualifications
pursuant to Sections 1.2, 1.3 and 1.4, all expenses other than underwriting discounts and
commissions (which shall be borne by the selling Holders of the Series C Preferred Stock pro rata
based on the number of Registrable Securities included in the registration) incurred in connection
with such registrations, filings or qualifications, including (without limitation) all
registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements
of counsel for the Company and the reasonable fees and disbursements of one counsel for all such
selling Holders, shall be borne by the Company in an amount not to exceed $50,000 per offering.
Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any
registration proceeding begun pursuant to Section 1.2 or Section 1.4 if the registration request is
subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to
be registered (in which case all participating Holders shall bear such expenses pro rata based upon
the number of Registrable Securities that were to be included in the withdrawn registration),
unless, in the case of a registration requested under Section 1.2, the Holders of a majority of the
Registrable Securities agree to forfeit their right to one demand registration pursuant to Section
1.2; provided, however, that if at the time of such withdrawal, the Holders have learned of a
material adverse change in the condition, business or prospects of the Company from that known to
the Holders at the time of their request and have withdrawn the request with reasonable promptness
following disclosure by the Company of such material adverse change, then the Holders shall not be
required to pay any of such expenses and shall retain their rights pursuant to Sections 1.2 and
1.4.

     1.8 Delay of Registration. No Holder shall have any right to obtain or seek an injunction
restraining or otherwise delaying any such registration as the result of any controversy that might
arise with respect to the interpretation or implementation of this Section 1.

     1.9 Indemnification. In the event any Registrable Securities are included in a registration
statement under this Section 1:

          (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder,
the partners, officers, directors, partners, members and shareholders of each Holder, legal counsel
and accountants for each Holder, any underwriter (as defined in the Act) for such Holder and each
person, if any, who controls such Holder or underwriter within the meaning of the Act or the 1934
Act, against any losses, claims, damages or liabilities (joint or several) to which they may become
subject under the Act, the 1934 Act, any other federal or
state securities laws or any rule or regulation promulgated thereunder, insofar as such
losses, claims, damages, or liabilities (or actions, proceedings or settlements in respect thereof)
arise out of or are based upon any of the following statements, omissions or violations
(collectively a “Violation”): (i) any untrue statement or alleged untrue statement of a material
fact contained in such registration statement, including any preliminary prospectus or final
prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged
omission to state in such registration statement a material fact required to be stated therein, or
necessary to make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any other federal or state securities laws or
any rule or regulation promulgated thereunder, and the Company will reimburse each such Holder,
underwriter,

10

 

controlling person or other aforementioned person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any such loss, claim,
damage, liability or action, proceeding or settlement as such expenses are incurred; provided,
however, that the indemnity agreement contained in this Section 1.9(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action, proceeding or settlement
if such settlement is effected without the consent of the Company (which consent shall not be
unreasonably withheld or delayed), nor shall the Company be liable in any such case for any such
loss, claim, damage, liability or action, proceeding or settlement to the extent that it arises out
of or is based upon a Violation that occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by any such Holder,
underwriter, controlling person or other aforementioned person; provided further, however, that the
foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the
benefit of any Holder or underwriter or other aforementioned person, or any person controlling such
Holder or underwriter, from whom the person asserting any such losses, claims, damages or
liabilities purchased shares in the offering, if a copy of the most current prospectus was not sent
or given by or on behalf of such Holder or underwriter or other aforementioned person to such
person, if required by law to have been so delivered, at or prior to the written confirmation of
the sale of the shares to such person, and if the prospectus (as so amended or supplemented) would
have cured the defect giving rise to such loss, claim, damage or liability and provided that the
Company had made available such prospectus for delivery by such Holder or underwriter.

          (b) To the extent permitted by law, each selling Holder will indemnify and hold harmless the
Company, each of its directors, each of its officers who has signed the registration statement,
each person, if any, who controls the Company within the meaning of the Act, legal counsel and
accountants for the Company, any underwriter, any other Holder selling securities in such
registration statement and any controlling person of any such underwriter or other Holder, against
any losses, claims, damages or liabilities (joint or several) to which any of the foregoing persons
may become subject, under the Act, the 1934 Act, any other federal or state securities laws or any
rule or regulation promulgated thereunder, insofar as such losses, claims, damages or liabilities
(or actions, proceedings or settlements in respect thereto) arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by such Holder expressly for use
in connection with such registration; and each such Holder will reimburse any person intended to be
indemnified pursuant to this Section 1.9(b) for any legal or
other expenses reasonably incurred by such person in connection with investigating or
defending any such loss, claim, damage, liability or action, proceeding or settlement as such
expenses are incurred; provided, however, that the indemnity agreement contained in this Section
1.9(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or
action, proceeding or settlement if such settlement is effected without the consent of the Holder
(which consent shall not be unreasonably withheld), and provided that in no event shall any
indemnity under this Section 1.9(b) exceed the net proceeds from the offering received by such
Holder, except in the case of fraud or willful misconduct by such Holder.

          (c) Promptly after receipt by an indemnified party under this Section 1.9 of notice of the
commencement of any action, proceeding or settlement (including any

11

 

governmental action), such
indemnified party will, if a claim in respect thereof is to be made against any indemnifying party
under this Section 1.9, deliver to the indemnifying party a written notice of the commencement
thereof and the indemnifying party shall have the right to participate in and, to the extent the
indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to
assume the defense thereof with counsel mutually satisfactory to the parties; provided, however,
that an indemnified party (together with all other indemnified parties that may be represented
without conflict by one counsel) shall have the right to retain one separate counsel, with the fees
and expenses to be paid by the indemnifying party, if representation of such indemnified party by
the counsel retained by the indemnifying party would be inappropriate due to actual or potential
differing interests between such indemnified party and any other party represented by such counsel
in such proceeding. The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action, if prejudicial to its ability to defend
such action, shall relieve such indemnifying party of liability to the indemnified party under this
Section 1.9 to the extent of such prejudice, but the omission to so deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.9.

          (d) The foregoing indemnity agreements of the Company and the selling Holders are subject to
the condition that, insofar as they relate to any loss, liability, claim, damage or expense
referred to herein arising from any untrue statement or alleged untrue statement of a material fact
contained in, or omission or alleged omission of a material fact from, a preliminary prospectus (or
necessary to make the statements therein not misleading) that has been corrected in the form of
prospectus included in the registration statement at the time it becomes effective, or any
amendment or supplement thereto filed with the SEC pursuant to Rule 424(b) under the Securities Act
(the “Final Prospectus”), such indemnity agreement shall not inure to the benefit of any Person if
a copy of the Final Prospectus was furnished to the indemnified party and such indemnified party
failed to deliver, at or before the confirmation of the sale of the shares registered in such
offering, a copy of the Final Prospectus to the Person asserting the loss, liability, claim, or
damage in any case in which such delivery was required by the Securities Act.

          (e) If the indemnification provided for in this Section 1.9 is held by a court of competent
jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim,
damage or expense referred to herein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute, subject to the limitations
described in Sections 1.9(a) and 1.9(b), to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage or expense in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one hand and the
indemnified party on the other hand in connection with the statements or omissions that resulted in
such loss, liability, claim, damage or expense, as well as any other relevant equitable
considerations; provided, however, that no contribution by any Holder, when combined with any
amounts paid by such Holder pursuant to Section 1.9(b), shall exceed the net proceeds from the
offering received by such Holder, except in the case of willful misconduct or fraud by such Holder.
The relative fault of the indemnifying party and the indemnified party shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to information furnished
expressly for use in

12

 

connection with such registration by the indemnifying party or by the
indemnified party and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission; provided, however, that, in any such
case, no Person guilty of fraudulent misrepresentation (within the meaning of section 11(f) of the
Securities Act) will be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

          (f) Notwithstanding the foregoing, to the extent that the provisions on indemnification and
contribution contained in the underwriting agreement entered into in connection with the
underwritten public offering are in conflict with the foregoing provisions, the provisions in the
underwriting agreement shall control; provided that should the underwriting agreement not address
an aspect of indemnification and contribution contained in this Section 1.9, that shall not
constitute a conflict for purposes of this Section 1.9(f).

          (g) The obligations of the Company and Holders under this Section 1.9 shall survive the
completion of any offering of Registrable Securities in a registration statement under this Section
1 and otherwise.

     1.10 Reports Under the 1934 Act. With a view to making available to the Holders the benefits of
Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell
securities of the Company to the public without registration or pursuant to a registration on Form
S-3, the Company agrees to:

          (a) make and keep public information available, as those terms are understood and defined in
Rule 144, at all times after the effective date of the Qualifying Public Offering;

          (b) file with the SEC in a timely manner all reports and other documents required of the
Company under the Act and the 1934 Act; and

          (c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith
upon request (i) a written statement by the Company that it has complied with the reporting
requirements of Rule 144 (at any time after ninety (90) days after the effective
date of the first registration statement filed by the Company), the Act and the 1934 Act (at
any time after it has become subject to such reporting requirements), or that it qualifies as a
registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies);
(ii) a copy of the most recent annual or quarterly report of the Company and such other reports and
documents so filed by the Company; and (iii) such other information as may be reasonably requested
to avail any Holder of any rule or regulation of the SEC that permits the selling of any such
securities without registration or pursuant to such form.

     1.11 Assignment of Registration Rights. The rights to cause the Company to register Registrable
Securities pursuant to this Section 1 may be assigned (but only with all related obligations) by a
Holder to a transferee or assignee of such securities that (i) is a subsidiary, parent or other
corporate affiliate of a Holder, or a partner, limited partner, retired partner or shareholder of a
Holder; (ii) is a Holder’s family member or trust for the benefit of an

13

 

individual Holder; or (iii)
after such assignment or transfer, holds at least two hundred fifty thousand (250,000) shares of
Registrable Securities (subject to appropriate adjustment for stock splits, stock dividends,
combinations or the like), provided: (A) the Company is, within a reasonable time after such
transfer, furnished with written notice of the name and address of such transferee or assignee and
the securities with respect to which such registration rights are being assigned; (B) such
transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of
this Agreement, including, without limitation, the provisions of Section 1.13 below; and (C) such
assignment shall be effective only if immediately following such transfer the further disposition
of such securities by the transferee or assignee is restricted under the Act.

     1.12 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the
Company shall not, without the prior written consent of the Holders of at least a majority of the
Registrable Securities and the Holders of at least a majority of the shares of Common Stock
issuable upon conversion of the Notes, enter into any agreement with any holder or prospective
holder of any securities of the Company that would allow such holder or prospective holder (a) to
include any of such securities in any registration filed under Section 1.2, Section 1.3 or Section
1.4 hereof, unless under the terms of such agreement, such holder or prospective holder may include
such securities in any such registration only to the extent that the inclusion of such securities
will not reduce the amount of the Registrable Securities of the Holders that are included, or (b)
to demand registration of their securities.

     1.13 “Market Stand Off” Agreement.

          (a) Each holder of equity securities of the Company that is a party to this Agreement (a
“Company Stockholder”) hereby agrees that it will not, without the prior written consent of the
managing underwriter, during the period commencing on the date of the final prospectus relating to
the Initial Offering and ending on the date specified by the Company
and the managing underwriter (such period not to exceed (a) one hundred eighty (l80) days (or
such longer period as the underwriters or the Company shall require in order to facilitate
compliance with NASD Rule 2711)) with respect to the Company’s Initial Offering and (b) ninety (90)
days with respect to a Company underwritten offering other than the Initial Offering, (i) lend,
offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or
dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into
or exercisable or exchangeable for Common Stock held immediately prior to the effectiveness of the
Registration Statement for such offering, or (ii) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of ownership of the
Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled
by delivery of Common Stock or other securities, in cash or otherwise. The foregoing provisions of
this Section 1.13 shall not apply to the sale of any shares to an underwriter pursuant to an
underwriting agreement. In addition, the provisions of this Section 1.13 shall only be applicable
to the Company Stockholders if (X) all officers and directors of the Company serving in such
positions as of the date hereof and any additional persons serving in any such positions on the
date of the applicable offering enter into similar agreements, (Y) the Company obtains a similar
covenant from the holders in interest of two percent (2%) or more of the outstanding securities of

14

 

the Company, and (Z) the Company uses all reasonable efforts to obtain a similar covenant from the
holders in interest of one percent (1%) or more of the outstanding securities of the Company. The
underwriters in connection with the Company’s Initial Offering are intended third-party
beneficiaries of this Section 1.13 and shall have the right, power and authority to enforce the
provisions hereof as though they were a party hereto. Each Company Stockholder further agrees to
execute such agreements as may be reasonably requested by the underwriters in the Company’s Initial
Offering that are consistent with this Section 1.13 or that are necessary to give further effect
thereto. Any discretionary waiver or termination of the restrictions of any or all of such
agreements or this Section 1.13 by the Company or the underwriters shall apply to all holders of
capital stock of the Company subject to such agreements pro rata based on the number of shares
subject to such agreements.

     In order to enforce the foregoing covenant, the Company may impose stop transfer instructions
with respect to the Registrable Securities of each Company Stockholder (and the shares or
securities of every other person subject to the foregoing restriction) until the end of such
period.

          (b) Each Company Stockholder agrees that a legend reading substantially as follows shall be
placed on all certificates representing all Registrable Securities of each Company Stockholder (and
the shares or securities of every other person subject to the restriction contained in this Section
1.13):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP
PERIOD OF UP TO 180 DAYS AFTER THE EFFECTIVE DATE OF THE ISSUER’S
REGISTRATION STATEMENT FILED UNDER THE ACT, AS AMENDED, AS SET FORTH IN AN
AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL HOLDER OF THESE SECURITIES, A
COPY OF WHICH
MAY BE OBTAINED AT THE ISSUER’S PRINCIPAL OFFICE. SUCH LOCK-UP PERIOD IS
BINDING ON TRANSFEREES OF THESE SHARES.

     1.14 Termination of Registration Rights. No Holder shall be entitled to exercise any right
provided for in this Section 1 (i) after five (5) years following the consummation of the
Qualifying Public Offering; (ii) as to any Holder, such earlier time after the Qualifying Public
Offering at which such Holder can sell all shares held by it in compliance with Rule 144(k); or
(iii) when the Company shall sell, convey, or dispose of all or substantially all of the Company’s
property or business or merge with or into or consolidate with any other corporation (other than a
wholly-owned subsidiary corporation) or effect any other transaction or series of related
transactions in which more than fifty percent (50%) of the voting power of the Company is disposed
of, in each case in a transaction in which the Holders receive, or at such later time at which the
Holders receive, cash, cash equivalents or Marketable Securities (as defined below) in
consideration for the Registrable Securities held by them; provided that this Section 1.14 shall
not cause the Holders’ registration rights to terminate following a merger effected solely for the
purpose of changing the domicile of the Company. For purposes of this Agreement, the term
“Marketable Securities” means securities that are listed on a national

15

 

securities exchange or
listed on the NASDAQ National Market System and either (i) freely tradeable by the Holders under
applicable securities laws on such exchange or system, or (ii) with respect to which the Holder has
received registration rights materially similar to those provided under Section 1 of this
Agreement.

     2. Covenants of the Company.

     2.1 Information Rights. For so long as an Investor (together with its respective affiliates)
continues to own at least ten percent (10%) of the Registrable Securities purchased pursuant to (i)
the Series C Purchase Agreement, or (ii) the Note Purchase Agreement, the Company shall deliver to
each Investor:

          (a) as soon as practicable, but in any event within one hundred twenty (120) days after the
end of each fiscal year of the Company, an income statement for such fiscal year, a balance sheet
of the Company and statement of shareholders’ equity as of the end of such year, and a statement of
cash flows for such year, such year end financial reports to be in reasonable detail, prepared in
accordance with generally accepted accounting principles (“GAAP”), and audited and certified by
independent public accountants of nationally recognized standing selected by the Company;

          (b) as soon as practicable, but in any event within forty-five (45) days after the end of each
of the first three (3) quarters of each fiscal year of the Company, an unaudited income statement,
statement of cash flows for such fiscal quarter and an unaudited balance sheet as of the end of
such fiscal quarter;

          (c) within forty-five (45) days of the end of each month an unaudited income statement,
statement of cash flows and balance sheet for and as of the end of such month, in reasonable
detail;

          (d) as soon as practicable, but in any event no later than the fifteenth (15th) of March of
each fiscal year, a budget and business plan for the next fiscal year, prepared on a monthly basis,
and, as soon as prepared, any other budgets or revised budgets prepared by the Company;

          (e) with respect to the financial statements called for in Sections 2.1(b) and 2.1(c), an
instrument executed by the Chief Financial Officer or President of the Company certifying that such
financials were prepared in accordance with GAAP consistently applied with prior practice for
earlier periods (with the exception of footnotes that may be required by GAAP) and fairly present
the financial condition of the Company and its results of operation for the period specified,
subject to year-end audit adjustment;

          (f) notices of default with respect to any obligation of the Company or its affiliates; and

          (g) such other information relating to the financial condition, business or corporate affairs
of the Company as the Investor may from time to time request, provided, however, that the Company
shall not be obligated under this Section 2.1(g) or any other

16

 

subsection of Section 2.1 to provide
information that it deems in good faith to be a trade secret or similar confidential information.

     2.2 Inspection. The Company shall permit each Investor, at such Investor’s expense, to visit and
inspect the Company’s properties, to examine its books of account and records and to discuss the
Company’s affairs, finances and accounts with its officers, all at such times during normal
business hours as may be requested by the Investor with reasonable advance notice; provided,
however, that the Company shall not be obligated pursuant to this Section 2.2 to provide access to
any information that it reasonably considers to be a trade secret or similar confidential
information.

     2.3 Termination of Information and Inspection Covenants. The covenants set forth in Sections 2.1
and 2.2 shall terminate and be of no further force or effect upon the earlier to occur of (i) the
consummation of a QIPO, (ii) when the Company first becomes subject to the periodic reporting
requirements of Sections 12(g) or 15(d) of the 1934 Act, or (iii) the consummation of a Deemed
Liquidation Event, as that term is defined in the Articles. Further, such covenants will terminate
and be of no further force or effect with respect to any Holder of a Note if such Holder does not
continue to hold an interest in the Note purchased by such Holder equal to at least thirty-three
percent (33%) of the balance of such Note (or the Common Stock into which such Note may have been
converted).

     2.4 Right of First Refusal. Subject to the terms and conditions specified in this Section 2.4, the Company hereby
grants to each Investor a right of first refusal to purchase all or any portion of its pro rata
portion of future sales by the Company of its Shares (as hereinafter defined). An Investor shall
include any general partners and affiliates of an Investor. Investors shall be entitled to
apportion the right of first refusal hereby granted it among itself and its partners and affiliates
in such proportions as it deems appropriate.

     Each time the Company proposes to offer any shares of, or securities convertible into or
exchangeable or exercisable for any shares of, its capital stock or debt instruments that are
issued along with warrants to purchase any of the foregoing (collectively, “Shares”), the Company
shall first make an offering to each Investor to purchase all or a portion of its pro rata portion
of such Shares in accordance with the following provisions:

          (a) The Company shall deliver a notice in accordance with Section 4.5 to the Investors stating
(i) its bona fide intention to offer such Shares, (ii) the number of such Shares to be offered, and
(iii) the price and terms upon which it proposes to offer such Shares.

          (b) By written notification received by the Company within twenty (20) calendar days after the
giving of Notice, each Investor may elect to purchase, at the price and on the terms specified in
the Notice, up to that portion of such Shares that equals the proportion that the number of shares
of Common Stock that are Registrable Securities issued and held by such Investor (assuming full
conversion and exercise of all convertible and exercisable securities then outstanding) bears to
the total number of shares of Common Stock of the Company then outstanding (assuming full
conversion and exercise of all convertible and exercisable securities then outstanding). The
Company shall promptly, in writing, inform each

17

 

Investor that elects to purchase all the shares
available to it (a “Fully-Exercising Investor”) of any other Investor’s failure to do likewise.
During the ten (10) day period commencing after such information is given, each Investor that is a
Fully-Exercising Investor may elect to purchase that portion of the Shares for which the Investors
were entitled to subscribe, but which were not subscribed for by the Investors, that is equal to
the proportion that the number of shares of Registrable Securities issued and held by such
Fully-Exercising Investor bears to the number of shares of Registrable Securities issued and held
by all Investors that are Fully-Exercising Investors.

          (c) If all Shares that Investors are entitled to obtain pursuant to Section 2.4(b) are not
elected to be obtained as provided in Section 2.4(b) hereof, the Company may, during the ninety
(90) day period following the expiration of the period provided in Section 2.4(b) hereof, offer the
remaining unsubscribed portion of such Shares to any person or persons at a price not less than
that, and upon terms no more favorable to the offeree than those, specified in the Notice. If the
Company does not enter into an agreement for the sale of the Shares within such period, or if such
agreement is not consummated within seventy-five (75) days of the execution thereof, the right
provided hereunder shall be deemed to be revived and such Shares shall not be offered unless first
reoffered to the Investors in accordance herewith.

          (d) The right of first refusal in this Section 2.4 shall not be applicable to (i) up to two
hundred seventeen thousand two hundred sixty eight (217,268) shares of
Common Stock (or options therefor) (subject to adjustment for stock splits, stock dividends,
recapitalizations and similar changes affecting the capital stock of the Company) to employees,
directors, consultants and other service providers of this corporation for the primary purpose of
soliciting or retaining their services pursuant to plans or agreements approved by a majority of
the Independent Directors; (ii) the issuance of securities pursuant to a Qualifying Public
Offering; (iii) the issuance of securities pursuant to the conversion or exercise of existing
convertible or exercisable securities or securities, the issuance of which would not be subject to
the right of first refusal set forth in Section 2.4 of this Agreement; (iv) the issuance of up to
an aggregate of one hundred thousand (100,000) shares of Common Stock (or securities convertible
into Common Stock) in connection with a bona fide business acquisition of or by the Company,
whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise; (v) the
issuance and sale of the Notes pursuant to the Note Purchase Agreement, as such agreement may be
amended; (vi) up to fifty thousand (50,000) shares of equity securities per year (subject to
adjustment for stock splits, stock dividends, recapitalizations and similar changes affecting the
capital stock of the Company) issued to vendors, consultants or advisors or in connection with
acquisitions, which grant, agreement or other arrangement has been approved by a majority of the
Independent Directors; (vii) shares of Common Stock or warrants to purchase Common Stock issued
pursuant to any strategic partnership, in each case approved by a majority of the Independent
Directors; and (viii) any securities issued in connection with any stock split, stock dividend or
recapitalization by the Company that affects all outstanding capital stock of the Company. In
addition to the foregoing, the right of first refusal in this Section 2.4 shall not be applicable
with respect to any Investor in any subsequent offering of Shares if (i) at the time of such
offering, the Investor is not an “accredited investor,” as that term is then defined in Rule 501(a)
of the Act, and (ii) such offering of Shares is otherwise being offered only to accredited
investors.

18

 

          (e) The rights provided in this Section 2.4 may not be assigned or transferred by any
Investor; provided, however, that (i) an Investor may assign or transfer such rights to any other
entity which controls, is controlled by or is under common control with the Investor or any entity
that is managed by the same joint management company of the Investor or any entity that is the
general partner or limited partner of the Investors, and (ii) an Investor that is a venture capital
fund may assign or transfer such rights to an affiliated venture capital fund.

     2.5 Proprietary Information and Inventions Agreements. The Company has caused each of the persons
listed on Schedule 2.5 attached hereto to execute and deliver a Proprietary Information and
Intellectual Property Agreement (a “Proprietary Information Agreement”) in form and substance
reasonably satisfactory to the Investors. Company shall use commercially reasonable efforts to
cause all officers, key management employees and employees involved in research and development
activities who are not listed on Schedule 2.5 attached hereto to execute and deliver a Proprietary
Information Agreement within thirty (30) days of the date of this Agreement, and shall require all
future officers, key management employees and employees involved in research and development
activities to execute and deliver a Proprietary Information Agreement.

     2.6 Lock-Up of Future Securityholders. The Company shall ensure that all future holders of the Company’s Series C Preferred Stock
and Notes are subject to a Market Stand-Off substantially similar to that set forth in Section 1.13
hereof.

     2.7 D&O Insurance. The Company has as of the date hereof, obtained from financially sound and
reputable insurer(s) and maintains director and officer liability insurance in the amount of at
least two million dollars ($2,000,000) per occurrence.

     2.8 Board of Directors. The Board shall consist of not less than six (6) and not more than nine
(9) members, at least a majority of whom shall be Independent Directors. Hiring and dismissal of
officers shall be under the purview of the Board, and the Board shall have exclusive authority over
all equity incentive grants and senior management compensation decisions; provided, however, that
without the prior written consent of the parties holding a majority of the Series C Preferred Stock
and the consent of parties holding a majority of shares of Common Stock issued or issuable upon
conversion of the Notes, which consent shall not be unreasonably withheld, the Board will not
materially increase the salary, bonuses, benefits or other compensation of the Company’s
management. For the avoidance of doubt, references to the Board in the previous sentence shall
include the Compensation Committee of the Board (the “Compensation Committee”), to the extent
appropriate and consistent with the charter of the Compensation Committee. The Board shall review
and approve the Company’s operating plan and budget annually as well as any material deviations
from or amendments to such plans and budgets.

     2.9 Board Observer.

          (a) The Investors holding a majority of the Registrable Securities issued or issuable upon
conversion of the Series C Preferred Stock shall be entitled to nominate one (1) Board observer
(the “Board Observer”) with full rights to observe and attend any and all

19

 

meetings and other
proceedings of the Company’s Board of Directors and to receive all notices and information provided
to the members of the Board. All out-of-pocket expenses of the Board Observer resulting from his
or her activities in such capacity shall be reimbursed by the Company. The right to appoint the
Board Observer pursuant to this Section 2.9(a) shall be transferable to any transferee of the
Investors holding shares of Series C Preferred Stock only to the extent that the transfer of such
rights has been consented to by a majority of the Board, which consent shall not be unreasonably
withheld.

          (b) The Investors holding a majority of the Registrable Securities issued or issuable upon
conversion of the Notes shall be entitled to nominate one (1) Board Observer with full rights to
observe and attend any and all meetings and other proceedings of the Company’s Board of Directors
and to receive all notices and information provided to the members of the Board. All out-of-pocket
expenses of the Board Observer resulting from his or
her activities in such capacity shall be reimbursed by the Company. The right to appoint the
Board Observer pursuant to this Section 2.9(b) shall be transferable to any transferee of the
Investors holding a Note only to the extent that the transfer of such rights has been consented to
by a majority of the Board, which consent shall not be unreasonably withheld. The Investors shall,
to the extent practicable, appoint a Board Observer designated by GE Energy Financial Services,
Inc.

     2.10 Related Party Transactions. The Company will not enter into any transaction with any
employee, officer, director or shareholder of the Company or any of its subsidiaries (a “Related
Party”) or member of such Related Party’s immediate family, or any corporation, partnership or
other entity in which such Related Party is an officer, director or partner, or in which such
Related Party has significant ownership interests or otherwise controls, is indebted to the Company
or any of its subsidiaries, other than on arms’-length basis as reasonably determined a majority of
the Independent Directors.

     2.11 Approval Rights. The approval of the Investors holding a majority of the shares of Common

proceeding;

          (b) amend, alter or repeal any provision of the Articles of Incorporation or Bylaws of the
Company other than in connection with a QIPO (as defined in the Notes) in a manner that adversely
affects the rights or preferences of the holders of the Notes or the holders of the shares of
Common Stock issued or issuable upon conversion of the Notes;

          (c) recapitalize, create or authorize the creation of any additional class or series of shares
of stock;

shares of Preferred Stock of the Company, Common Stock or shares of any additional class or series
of shares of stock;

20

 

          (e) purchase or redeem, or set aside any sums for the purchase or redemption of, or pay any
dividend or make any distribution on, any shares of stock ranking junior to the Notes, except for
repurchases of Series C Preferred Stock in accordance with Section 3.9.6 of the Articles;

          (f) authorize or issue any equity securities other than the following authorizations or
issuances:

               (i) Common Stock pursuant to the Company’s stock purchase and stock option plans approved by a
majority of the members of the Board of Directors who are not employees of the Company and were not
employees of the Company during the twenty-four month period prior to the date of such approval
(the “Independent Directors”);

               (ii) shares of Common Stock issued pursuant to the exercise of options, warrants or

21

 

     3. Transfers of Registrable Securities.

     3.1 Transfer Notice. If at any time an Investor desires to Transfer any Registrable Securities (a “Selling
Investor”), the Selling Investor shall promptly give the Company written notice thereof (the
“Transfer Notice”). The Transfer Notice shall include a description and the amount of the
Registrable Securities that the Selling Investor desires to Transfer (for the purposes of this
Section 3, the “Offered Shares”). In the event that the Transfer is being made pursuant to the
provisions of Section 3.3, the Transfer Notice shall state under which specific subsection the
Transfer is being made. If the Company so elects within ten (10) days following receipt of such
notice, the Company shall have the right, on an exclusive basis, for a period of forty-five (45)
days after receipt of such notice to negotiate with the Selling Investor with respect to a
definitive agreement for the sale and purchase of all (and not less than all) of the Offered
Shares. The Selling Investor and the Company shall negotiate in good faith the terms and
conditions of any such agreement.

     3.2 Non-Exercise of Rights. To the extent that the Company does not exercise its right to
negotiate with the Selling Investor or the Company and the Selling Investor do not reach an
agreement for the sale and purchase of the Offered Shares within the time periods specified in
Section 3.1, the Selling Investor shall have a period of ninety (90) days from the expiration of
such rights in which to sell the Offered Shares to a third-party transferee(s), on terms and
conditions no less favorable to the Selling Investor than the terms proposed by the Company
pursuant to Section 3.1 hereof (if applicable). The third-party transferee(s) shall acquire the
Offered Shares free and clear of subsequent rights of first offer under this Agreement. In the
event the Selling Investor does not sell the Offered Shares within the ninety (90) day period from
the expiration of these rights, the Company’s first offer rights shall continue to be applicable to
any subsequent disposition of the Offered Shares by the Selling Investor until such rights lapse in
accordance with the terms of this Agreement. Furthermore, the exercise or non-exercise of the
rights of the Company under Section 3.1 to offer to purchase Registrable Securities from the
Selling Investor shall not adversely affect its right to make subsequent purchases from the Selling
Investor of Registrable Securities.

     3.3 Limitations to Company Right of First Offer. Notwithstanding the provisions of Section 3.1 of
this Agreement, the first offer right of the Company shall not apply to (a) in the case of a
company, corporation or a partnership, to the Transfer of Equity Securities to any members,
shareholders, partners or corporate affiliates thereof (each, an “Indirect Shareholder” of the
Company) or to any entity controlled by, controlling or under common control with the transferor;
(b) to the Transfer of Equity Securities to any spouse or member of an Investor’s Immediate Family,
or to a custodian, trustee (including a trustee of a voting trust), executor, or other fiduciary
for the account of the Investor’s or Indirect Shareholder’s spouse or members of the Investor’s
immediate family, or to a trust for the Indirect Shareholder’s own self, or a charitable remainder
trust; (c) Transfers of Equity Securities by one or more individual Investors pursuant to which
after such Transfer, (i) if Common Stock issued or issuable upon conversion of the Notes is
proposed to be transferred by GE, GE will continue to collectively own at least one million
(1,000,000) shares (including shares held by transferees pursuant to clauses (a) and (b) above) of
such Common Stock (subject
to adjustment for stock splits, stock dividends, recapitalizations and similar changes
affecting the capital stock of the Company)

22

 

subsequent to such Transfer, (ii) if Series C Preferred
Stock (or Common Stock issued upon the conversion thereof) and/or Common Stock issued or issuable
upon conversion of the Notes is proposed to be transferred by Clean Technology Fund II, LP (“CTF”),
CTF will continue to collectively own at least three hundred twelve thousand five hundred (312,500)
shares (including shares held by transferees pursuant to clauses (a) and (b) above) of such Series
C Preferred Stock (or Common Stock issued upon the conversion thereof) and/or Common Stock (subject
to adjustment for stock splits, stock dividends, recapitalizations and similar changes affecting
the capital stock of the Company) subsequent to such Transfer; (iii) if Series C Preferred Stock
(or Common Stock issued upon the conversion thereof) and/or Common Stock issued or issuable upon
conversion of the Notes is proposed to be transferred by CapVest Venture Fund, LP (“CapVest”) or
Technology Transformation Venture Fund, LP (“TTVF”), CapVest and TTVF will continue to collectively
own at least twelve thousand five hundred (12,500) shares (including shares held by transferees
pursuant to clauses (a) and (b) above) of such Series C Preferred Stock (or Common Stock issued
upon the conversion thereof) and/or Common Stock (subject to adjustment for stock splits, stock
dividends, recapitalizations and similar changes affecting the capital stock of the Company)
subsequent to such Transfer; or (d) any sale of Registrable Securities to the public pursuant to a
registration statement filed with, and declared effective by, the SEC under the Act; provided,
however, that in the event of any transfer made pursuant to one of the exemptions provided by
clauses (a) or (b), the Investor shall inform the Company in writing of such Transfer prior to
effecting it and (ii) each such transferee or assignee, prior to the completion of the Transfer,
shall have executed documents assuming the obligations of the Investor under this Agreement with
respect to the transferred Registrable Securities. Except with respect to the Registrable
Securities transferred under clauses (c) and (d) above (which Registrable Securities shall no
longer be subject to the first offer rights of the Company), such transferred Registrable
Securities shall remain “Registrable Securities” hereunder, and such pledgee, transferee or donee
shall be treated as the “Investor” for purposes of this Agreement. For purposes of this Section
3.3, “Investor’s immediate family” shall include any spouse, father, mother, sibling or lineal
descendant of Holder, Holder’s spouse or an Indirect Shareholder.

     4. Miscellaneous.

Purchase Agreement”); and

     WHEREAS, under Section 10 of the Original Agreement, the Original Agreement may be amended by
the written consent of the Company and the holders of a majority of the Company’s Common Stock
(assuming full conversion of all shares of Preferred Stock owned by all of the Series C Investors
at the conversion rate effective on the date herewith);

     NOW, THEREFORE, in consideration of the foregoing premises and certain other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto
hereby agree as follows:

     For purposes of this Agreement, the following terms have the meanings specified below:

 

 

          (a) Common Stock. “Common Stock” means the Common Stock of the Company.

          (b) Delivery. “Delivery” has the meaning set forth in Section 6 below.

          (c) Equity Securities. “Equity Securities” means any securities now or hereafter

an Investor or Shareholder in accordance with the provisions of Section 2.3 or Section 3 of this
Agreement.

          (e) Independent Director. “Independent Director” has the same meaning as set forth in
the Company’s Amended and Restated Articles of Incorporation dated as of July 31, 2006.

          (f) Preferred Stock. “Preferred Stock” means the Preferred Stock of the Company.

          (g) QIPO. “QIPO” means the closing of the sale of shares of Common Stock at

proceedings or general assignees for the benefit of creditors, whether voluntary, involuntarily or
by operation of law, directly or indirectly, of any of the Equity Securities.

     2. Agreements Among the Parties.

     2.1 Investors’ Rights of First Offer.

          (a) If at any time a Shareholder desires to make a Transfer or series of related Transfers of
Equity Securities (and thereby become an “Offering Holder”), then unless such Transfer is excluded
under Section 2.3, the Offering Holder shall promptly give the Company and each Investor written
notice thereof (the “Offer Notice”). The Offer Notice shall include a description and the amount
of the Equity Securities that the Holder desires to Transfer (for the

2

 

purposes of this Section 2.1, the “Offered Shares”). If any Investors so elect within ten
(10) days following receipt of such notice (each, an “Electing Investor”), the Electing Investors
shall have the right, on an exclusive basis, for a period of forty-five (45) days after receipt of
such notice to negotiate with the Offering Holder with respect to a definitive agreement for the
sale and purchase of the Offered Shares. The Offering Holder and the Electing Investors shall
negotiate in good faith the terms and conditions of any such agreement.

          (b) Unless the Electing Investors agree otherwise, in the event that the Offering Holder and
the Electing Investors agree to final terms and conditions for the Transfer of the Offered Shares,
each Electing Investor shall be entitled to purchase all of its respective pro rata share of the
Offered Shares pursuant to such Transfer. Each Electing Investor’s pro rata share of the Offered
Shares shall be a fraction of the Offered Shares, the numerator of which shall be the number of
shares of Common Stock (including shares of Common Stock issuable upon conversion of Preferred
Stock or the Notes) owned by such Electing Investor and denominator of which shall be the total
number of shares of Common Stock (including shares of Common Stock issuable upon conversion of
Preferred Stock or the Notes) held by all Electing Investors.

          (c) In the event any Electing Investor elects not to purchase all of its pro rata share of the
Offered Shares available pursuant to its option under Section 2.1(b), each Electing Investor that
has elected to purchase all of its respective pro rata share of the Offered Shares (each, a “Fully
Participating Investor”) shall be entitled to purchase its respective pro rata share of all
unsubscribed shares (including any shares that are unsubscribed due to any other Fully
Participating Investor not exercising its option to purchase unsubscribed shares). For purposes of
this Section 2.1(c), the numerator shall be the same as that used in Section 2.1(b) above and the
denominator shall be the total number of shares of Common Stock (including shares of Common Stock
issuable upon conversion of Preferred Stock or the Notes) owned by all Fully Participating
Investors. Each Electing Investor shall be entitled to apportion Offered Shares to be purchased
among its partners and affiliates (including in the case of a venture capital fund other venture
capital funds affiliated with such fund), provided that such Electing Investor notifies the
Offering Holder of such allocation.

          (d) To the extent that none of the Investors exercise their right to negotiate with the
Offering Holder or the Electing Investors and the Offering Holder do not reach an agreement for the
sale and purchase of the Offered Shares within the time periods specified in Section 2.1(a), the
Offering Holder shall have a period of ninety (90) days from the expiration of such rights in which
to sell the Offered Shares to a third-party transferee(s), on terms and conditions no less
favorable to the Offering Holder than the terms proposed by any of the Electing Investors pursuant
to Section 2.1(a) hereof (if applicable). In the event the Offering Holder does not sell the
Offered Shares within the ninety (90) day period from the expiration of these rights, the
Investors’ first offer rights shall continue to be applicable to any subsequent disposition of the
Offered Shares by the Offering Holder until such rights lapse in accordance with the terms of this
Agreement. Furthermore, the exercise or non-exercise of the rights of the Investors under this
Section 2.1 to offer to purchase Equity Securities from the Offering Holder shall not adversely
affect their rights to make subsequent purchases from the Offering Holder of Equity Securities or
subsequently participate in sales of Equity Securities by a Selling Shareholder pursuant to Section
2.2 hereof. Any definitive agreement for the sale and purchase of the Offered Shares to a

3

 

third-party transferee(s) shall be subject to the Investors’ right of co-sale pursuant to
Section 2.2 hereof.

     2.2 Rights of Co-Sale.

          (a) In the event the Investors fail to exercise their rights under Section 2.1 or do not reach
an agreement for the purchase and sale of the Offered Shares within the time periods specified in
Section 2.1(a), and if at any time thereafter a Shareholder proposes to Transfer Equity Securities
(and thereby become a “Selling Holder”), the Selling Holder shall promptly give the Company and
each Investor written notice of the Selling Holder’s intention to make the Transfer (for purposes
of this Section 2.2, the “Transfer Notice”). The Transfer Notice shall include (i) a description
of the Equity Securities to be transferred (for purposes of this Section 2.2, the “Offered
Shares”), (ii) the name(s) and address(es) of the prospective transferee(s), (iii) the
consideration, and (iv) the material terms and conditions upon which the proposed Transfer is to be
made. The Transfer Notice shall certify that the Selling Holder has received a firm offer from the
prospective transferee(s) and in good faith believes a binding agreement for the Transfer is
obtainable on the terms set forth in the Transfer Notice. The Transfer Notice shall also include a
copy of any written proposal, term sheet or letter of intent or other agreement relating to the
proposed Transfer. In the event that the Transfer is being made pursuant to the provisions of
Section 2.3, the Transfer Notice shall state under which specific subsection the Transfer is being
made.

          (b) Each Investor that notifies the Company and the Selling Holder in writing within five (5)
days after Delivery of a Transfer Notice referred to in Section 2.2(a) that it wishes to exercise
its rights of co-sale (a “Co-selling Investor”) shall have the right to participate in such sale of
Equity Securities on the same terms and conditions as specified in the Transfer Notice. Such
Co-selling Investor’s notice to the Company and the Selling Holder shall indicate the maximum
number of shares of capital stock of the Company that the Co-selling Investor wishes to sell under
his, her or its right to participate. To the extent one or more of the Investors exercise such
right of participation in accordance with the terms and conditions set forth below, the number of
shares of Equity Securities that the Selling Holder may sell in the Transfer shall be
correspondingly reduced.

          (c) Each Co-selling Investor may sell all or any part of that number of shares of capital
stock of the Company equal to the product obtained by multiplying (i) the aggregate number of
shares of Equity Securities covered by the Transfer Notice by (ii) a fraction, the numerator of
which is the number of shares of Common Stock (including shares of Common Stock issuable upon
conversion of Preferred Stock or the Notes) owned by the Co-selling Investor on the date of the
Transfer Notice and the denominator of which is the total number of shares of Common Stock
(including shares of Common Stock issuable upon conversion of Preferred Stock or the Notes) owned
by the Selling Shareholder and all of the Co-selling Investors on the date of the Transfer Notice.

4

 

          (d) Each Co-selling Investor shall effect its participation in the sale by promptly delivering
to the Selling Holder for transfer to the prospective purchaser one or more certificates, properly
endorsed for transfer to the purchaser, which represent:

               (i) if the Offered Shares are shares of Series C Preferred Stock, the number of shares of
Series C Preferred Stock of the Company that such Co-selling Investor elects to sell, or that
number of shares of Common Stock equal to the as converted to Common Stock equivalent of that
number of Offered Shares that the Selling Holder (together with any other Co-selling Investors)
would be permitted to sell if the Co-selling Investor were not participating in the sale;

               (ii) if the Offered Shares are shares of Preferred Stock other than shares of Series C
Preferred Stock, that number of shares of Series C Preferred Stock or Common Stock equal to the as
converted to Common Stock equivalent of that number of Offered Shares that the Selling Holder
(together with any other Co-selling Investors) would be permitted to sell if the Co-selling
Investor were not participating in the sale;

               (iii) if the Offered Shares are shares of Common Stock, that number of shares of Common Stock,
or such number of Equity Securities that are at such time convertible into the number of shares of
Common Stock, that such Co-selling Investor elects to sell;

provided, however, that if the prospective third-party purchaser objects to the delivery of shares
of capital stock of the Company in lieu of Common Stock, or the Co-Selling Investor desires to
deliver Common Stock issuable upon the conversion of a Note, such Co-selling Investor shall convert
such shares of capital stock of the Company or such Note into Common Stock and deliver Common Stock
as provided in this Section 2.2. The Company agrees to make any such conversion concurrent with
the actual transfer of such shares to the purchaser and contingent on such transfer.

          (e) The stock certificate or certificates that the Co-selling Investor delivers to the Selling
Shareholder pursuant to Section 2.2(d) shall be transferred to the prospective purchaser in
consummation of the sale of the Equity Securities pursuant to the terms and conditions specified in
the Transfer Notice, and the prospective purchaser shall concurrently therewith remit to such
Co-selling Investor that portion of the sale proceeds to which such Co-selling Investor is entitled
by reason of its participation in such sale. To the extent that any prospective purchaser or
purchasers prohibits such assignment or otherwise refuses to purchase shares or other securities
from a Co-selling Investor exercising its rights of co-sale hereunder, the Selling Holder shall not
sell to such prospective purchaser or purchasers any Equity Securities unless and until,
simultaneously with such sale, the Selling Holder shall purchase such shares or other securities
from such Co-selling Investor for the same consideration and on the same terms and conditions as
the proposed transfer described in the Transfer Notice. In the event that a Co-selling Investor
elects to participate in a sale of Equity Securities pursuant to this Section 2.2, and
notwithstanding such election any Selling Holder fails to comply with such election, such Selling
Holder agrees to purchase the Equity Securities held by such Co-selling Investor in accordance with
this Agreement provided such Co-selling Investor has otherwise complied with the provisions of this
Section 2.2.

5

 

          (f) To the extent that the Investors have not exercised their right to participate in the sale
of the Offered Shares within the time periods specified in Section 2.2(b), the Selling Holder shall
have a period of ninety (90) days from the expiration of such rights in which to sell the Offered
Shares upon terms and conditions (including the purchase price) no more favorable than those
specified in the Transfer Notice, to the third-party transferee(s) identified in the Transfer
Notice. The third-party transferee(s) shall acquire the Offered Shares free and clear of
subsequent rights of first offer and co-sale under this Agreement. In the event the Selling Holder
does not consummate the sale or disposition of the Offered Shares within the ninety (90) day period
from the expiration of these rights, the Investors’ first offer and co-sale rights shall continue
to be applicable to any subsequent disposition of the Offered Shares by the Selling Holder until
such right lapses in accordance with the terms of this Agreement. Furthermore, the exercise or
non-exercise of the rights of the Investors under this Section 2.2 to participate in sales of
Equity Securities by the Selling Holder shall not adversely affect their rights to make subsequent
offers to purchase from the Selling Holder of Equity Securities or subsequently participate in
sales of Equity Securities by the Selling Shareholder.

     2.3 Limitations to Rights of First Offer and Co-Sale.

          (a) Notwithstanding the provisions of Section 2.1 and Section 2.2 of this Agreement, the first
offer and co-sale rights of the Investors shall not apply (i) in the case of a company, corporation
or a partnership, to the Transfer of Equity Securities to any members, shareholders or partners
thereof (each, an “Indirect Shareholder” of the Company) or to any entity controlled by,
controlling or under common control with the transferor; (ii) to the Transfer of Equity Securities
to any spouse or member of a Holder’s Immediate Family, or to a custodian, trustee (including a
trustee of a voting trust), executor, or other fiduciary for the account of the Holder’s or
Indirect Shareholder’s spouse or members of the Holder’s immediate family, or to a trust for the
Indirect Shareholder’s own self, or a charitable remainder trust; or (iii) to a QIPO; provided,
however, that in the event of any transfer made pursuant to one of the exemptions provided by
clauses (i) or (ii), (I) the Holder shall inform the Investors and the Company in writing of such
Transfer prior to effecting it, and (II) each such transferee or assignee, prior to the completion
of the Transfer, shall have executed documents assuming the obligations of the Holder under this
Agreement with respect to the transferred Equity Securities. Except with respect to the Equity
Securities transferred under clause (iii) above (which Equity Securities shall no longer be subject
to the first offer or co-sale rights of the of the Investors), such transferred Equity Securities
shall remain “Equity Securities” hereunder, and such pledgee, transferee or donee shall be treated
as the “Holder” for purposes of this Agreement. For purposes of this Section 2.3(a), “Holder’s
Immediate Family” shall include any spouse, father, mother, sibling or lineal descendant of Holder,
Holder’s spouse or an Indirect Shareholder.

          (b) Notwithstanding the provisions of Section 2.1 of this Agreement, the rights of first offer
of the Investors shall not apply to Transfers of Equity Securities of one or more individual
Shareholders until the aggregate amount of such sales after the date hereof shall equal $1,000,000;
provided, however, that the purchase of Equity Securities by the Company in connection with the
termination of a Shareholder’s employment with the Company shall not be a Transfer included in the
$1,000,000 threshold.

6

 

          (c) Notwithstanding the provisions of Section 2.2 of this Agreement, a majority in interest of
the Common Stock issuable upon the conversion of the Series C Preferred Stock and a majority in
interest of the Common Stock issuable upon the conversion of the Notes held by the Investors may
waive in writing the co-sale rights with respect to a given Transfer. Moreover, the co-sale rights
of the Investors shall not apply to (i) any Transfers of Equity Securities of one or more
individual Shareholders until the aggregate amount of such Transfers after the date hereof shall
equal $1,000,000, exclusive of any Transfers of Equity Securities within any fiscal year by
individual Shareholders of up to twenty percent (20%) of the Equity Securities (including for such
purpose any Equity Securities which are the subject of options or other rights to purchase) held by
such Shareholder on the date hereof until such $1,000,000 limitation is achieved; and (ii) the
purchase of Equity Securities by the Company in connection with the termination of a Shareholder’s
employment with the Company. Notwithstanding the foregoing, however, any proposed Transfer by Neal
R. Verfeurth that would result in him owning less than sixty percent (60%) of the number of shares
of the Company’s Common Stock that he owned on the date hereof (excluding unexercised options),
whether or not the $1,000,000 threshold has been achieved, shall be subject to the Investors’
rights of co-sale set forth in Section 2.2.

     2.4 Right of Stock Transfer. The parties hereto agree that no Holder shall Transfer
Equity Securities to any competitor of the Company. If at any time a Holder proposes to Transfer
Equity Securities, it shall notify the Company of the identity of such transferee no later than
ten (10) business days prior to entering into a definitive agreement with respect to such Transfer.
If a majority of the Independent Directors reasonably determines within such ten (10) business day
period that the proposed transferee is a competitor of the Company and that such Transfer would not
be in the best interest of the Company, the Board shall immediately notify the Holder of such
determination and the Holder shall be prohibited from transferring any Equity Securities to such
proposed transferee; provided, however, that the Board’s consent to Transfer by an Investor shall
not be unreasonably withheld.

     Any sale, assignment, transfer, pledge, hypothecation or other encumbrance or disposition of
Equity Securities not made in conformance with this Agreement or in violation of applicable law
shall be null and void, shall not be recorded on the books of the Company and shall not be
recognized by the Company.

     3. Assignments and Transfers; No Third-Party Beneficiaries. This Agreement and the
rights and obligations of the parties hereunder shall inure to the benefit of, and be binding upon,
their respective successors, assigns and legal representatives, but shall not otherwise be for the
benefit of any third party. The rights of the Investors hereunder are only assignable (a) to any
other Investor; (b) to a partner, member or affiliate of such Investor (including affiliated
venture capital funds of which such Investor is a partner or member); or (c) to an assignee or
transferee who acquires (i) all of the Equity Securities held by a particular Investor, (ii) at
least two hundred fifty thousand (250,000) shares of the Series C Preferred Stock (or shares of
Common Stock into which such Series C Preferred Stock has been converted) purchased pursuant to the
Series C Purchase Agreement (subject to adjustment for stock splits, stock dividends,
recapitalizations and similar changes affecting the capital stock of the Company) from such
Investor, or (iii) an interest in a Note convertible into at least two hundred fifty thousand
(250,000) shares of Common Stock into which the Notes may have been converted or a portion of a
Note convertible into at least two hundred fifty thousand (250,000) shares of Common Stock,
purchased pursuant to the Note

7

 

(subject to adjustment for stock splits, stock dividends, recapitalizations and similar
changes affecting the capital stock of the Company) from such Investor.

     4. Legend. Each existing or replacement certificate for shares now owned or hereafter
acquired by the Holders shall bear the following legend upon its face:

“THE SALE, PLEDGE, HYPOTHECATION, ASSIGNMENT OR TRANSFER OF THE
SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS
AND CONDITIONS OF A CERTAIN FIRST OFFER AND CO-SALE AGREEMENT BY AND
BETWEEN THE SHAREHOLDER, THE CORPORATION AND CERTAIN HOLDERS OF
STOCK OF THE CORPORATION. COPIES OF SUCH AGREEMENT MAY BE OBTAINED
UPON WRITTEN REQUEST TO THE SECRETARY OF THE CORPORATION.”

     5. Effect of Change in Company’s Capital Structure. If, from time to time, the
Company pays a stock dividend or effects a stock split or other change in the character or amount
of any of the outstanding stock of the Company, then in such event any and all new, substituted or
additional securities to which a Holder is entitled by reason of such Holder’s ownership of Equity
Securities shall be immediately subject to the rights and obligations set forth in this Agreement
with the same force and effect as the stock subject to such rights immediately before such event.

     6. Notices. All notices and other communications given or made pursuant hereto shall
be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be
notified; (ii) when sent by confirmed electronic mail or facsimile if sent during normal business
hours of the recipient; if not, then on the next business day; (iii) five (5) days after having
been sent by registered or certified mail, return receipt requested, postage prepaid; or (iv) one
(1) business day after deposit with a nationally recognized overnight courier, specifying next day
delivery, with written verification of receipt. The occurrence of the events set forth in
subsections (i) through (iv) above shall constitute “Delivery” of notice. All communications shall
be sent to the respective parties at the addresses set forth on the signature pages attached hereto
(or at such other addresses as shall be specified by notice given in accordance with this
Section 6).

     7. Further Instruments and Actions. 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. Each such party agrees to cooperate affirmatively with each other party, and to
the extent reasonably requested by any such party, to enforce rights and obligations pursuant
hereto.

     8. Term. This Agreement shall terminate and be of no further force or effect upon
(a) the consummation of the Company’s sale of its Common Stock or other securities pursuant to an
initial public offering under the Securities Act of 1933, or (b) the consummation of a Deemed
Liquidation Event, as such term is defined in the Company’s Amended and Restated Articles of
Incorporation. This Agreement shall terminate with respect to any Shareholder upon the termination
of such Shareholder as an officer or director of the Company.

8

 

     9. Amendments and Waivers. Any term of this Agreement may be amended and the
observance of any term of this Agreement may be waived (either generally or in a particular
instance and either retroactively or prospectively) only with the written consent of the Company
and the Investors holding at least a majority of the shares of Common Stock and a majority of the
shares of Common Stock issuable upon conversion of the Notes (assuming full conversion at the then
effective conversion rate of all shares of Preferred Stock or Notes owned by all of the Investors)
held by all Investors. Notwithstanding the foregoing, in the event that such amendment or waiver
adversely affects the obligations or rights of a Shareholder under this Agreement, such amendment
or waiver shall also require the written consent of such adversely affected Shareholder or, if

EMPLOYEE

PROPRIETARY INFORMATION

AND INTELLECTUAL PROPERTY AGREEMENT

	 	 	 
	 

(name of employee)

	 	 
	 
	 	 
	 

(address)

	 	 
	 
	 	 
	 

	 	 

          In consideration of my employment by Orion Energy Systems, Ltd. (the “Company”), the
compensation received by me from the Company from time to time, and the grant of an incentive stock
option made by the Company to me, the receipt and sufficiency of which is hereby acknowledged, the
Company and I agree as follows:

     1. I understand that the Company possesses and will possess Proprietary Information which is
important to its or its affiliates’ or clients’ business. For purposes of this Agreement,
“Proprietary Information” is all information, whether or not made verbally or in writing or other
tangible or intangible form, that was or will be developed, created, or discovered by or on behalf
of the Company or its affiliates or clients, or which became or will become known by, or was or is
conveyed to the Company or its affiliates or clients, which has value in the Company’s or its
affiliates’ or clients’ business, or is considered, deemed or treated as confidential by the
Company, its affiliates or clients or is otherwise not generally known. “Proprietary Information”
includes, but is not limited to, the proprietary integrated sales management system developed and
maintained by the Company providing various sales methodology, technology, financial and marketing
solutions including customer relationship management, financial management, product and service
information; information concerning the Company’s business, products, and affairs which may be or
has been developed or belongs to or is otherwise possessed by the Company; product and engineering
specifications; proprietary tooling information; performance analyses of the Company’s products;
inventions and ideas; research and development; current and planned manufacturing or distribution
methods and processes; customer lists; current and anticipated customer requirements; market
studies; business plans; financial information; and other business and strategic information; trade
secrets, ideas, methodologies, skills, knowledge, computer programs, computer codes, databases,
database criteria, user profiles, algorithms, modules, scripts, features and modes of operation,
designs, technology, ideas, know-how, processes, data, techniques, internal documentation,
improvements, inventions (whether patentable or not), works of authorship, technical, business,
financial, client, marketing, and product development plans, forecasts, the salaries and terms of
compensation of other employees, client and supplier lists, contacts at or knowledge of clients or
prospective clients of the Company or its affiliates, and other information concerning the
Company’s or its affiliates’ or clients’ actual or anticipated products or services, business,
research or development, or any information which is received in confidence by or for the Company
from any other person. Proprietary Information shall not include publicly available information
(in substantially the

Dec
2006

 

 

same form in which it is publicly available) unless such information is publicly available by
reason of unauthorized disclosure.

     2. I understand that my employment creates a relationship of confidence and trust between me
and the Company with respect to Proprietary Information. I agree to take all measures necessary to
safeguard and protect the Proprietary Information of the Company, its affiliates and clients. I
agree to keep in strict confidence, and not to directly or indirectly, at any time during or for up
to two years after my employment with the Company ends, disclose, furnish, disseminate, make
available, or, except solely in the course of performing my duties of employment with the Company,
during my employment, use any Proprietary Information. I understand and agree that the Proprietary
Information could be used or disseminated anywhere in the United States and Canada, and if so used
or disseminated without Company permission could seriously harm the Company. Accordingly, I agree
that the scope of this provision is as to the entire United States and Canada. I understand that
this Agreement relates to Proprietary Information and does not prohibit me from being employed with
any other employer, although such a prohibition may be contained in a separate noncompetition
agreement that I may enter into with the Company.

     3. During my employment at the Company, I may be exposed to trade secrets of the Company, its
affiliates or clients. Nothing in this Agreement diminishes or limits any protection granted by
law to trade secrets or relieves me of any duty not to disclose, use, or misappropriate any
information that is a trade secret for as long as such information remains a trade secret.

          4. I understand that the Company possesses or will possess “Company Materials” which are
important to its or its affiliates’ or clients’ business. For purposes of this Agreement, “Company
Materials” are documents, apparatus, equipment and any other property of the Company, or any
reproduction of such property or other media or tangible items that contain or embody Proprietary
Information or any other information or material concerning the business, operations or plans of
the Company or its affiliates or clients, whether such documents have been prepared by me or by
others. “Company Materials” include, but are not limited to, computers, computer software,
computer disks, tapes, printouts, source, HTML and other code, flowcharts, schematics, designs,
graphics, trademarks, service marks, logos, trade dress, domain names, drawings, photographs,
charts, graphs, notebooks, customer lists, sound recordings, other tangible or intangible
manifestation of content, and all other documents and materials whether printed, typewritten,
handwritten, electronic, or stored on computer disks, tapes, hard drives, or any other tangible
medium, as well as samples, prototypes, models, products and the like.

          a. All Proprietary Information, Company Materials, and all title, rights, interests, patents,
patent rights, copyrights, trademark and service mark rights and all goodwill associated therewith,
trade secret rights, and other intellectual property and rights anywhere in the world of any kind
(collectively “Rights”) in connection with such Proprietary Information and Company Materials shall
be the sole and exclusive property of the Company. I hereby assign to the Company any Rights I may
have or acquire in such Proprietary Information or Company Materials.

     b. I agree that during my employment by the Company, I will not deliver any Company Materials
to any person or entity except as I am required to do in connection with

Dec
2006

performing the duties of my employment. I further agree that, immediately upon the
termination of my employment by me or by the Company for any reason, or during my employment if so
requested by the Company, I will return all Company Materials, excepting only (i) my personal
copies of records relating to my compensation; and (ii) my copy of this Agreement. I shall also
provide any information, such as passwords or codes, necessary to allow the Company to fully
utilize its property.

          c. I will promptly disclose in writing to my immediate supervisor, with a copy to the
President or Chief Executive Officer of the Company, or to any persons designated by the Company,
all Company Developments. “Company Developments” shall include, without limitation, all
Developments made, conceived, reduced to practice, suggested or developed by me, either alone or
jointly with others, during the term of my employment and during the one year period thereafter,
whether or not during usual business hours and whether or not on the premises of the Company or its
affiliates that (i) result in any way from the performance of my duties or obligations for the
Company or its affiliates, (ii) relate in any way to the past, present or anticipated products,
services or business of the Company or its affiliates, or (iii) were made, conceived, reduced to
practice, suggested or developed in any way using or otherwise relying on any Company Materials,
Proprietary Information or Rights of the Company or any of its affiliates. “Developments” shall
include, without limitation, any work of authorship, discovery, improvement, invention, design,
graphic, trademark, service mark, trade dress, logo, domain name, source, HTML and other code,
trade secret, technology, algorithms, computer program, audio, video or other files or content,
idea, design, process, technique, know-how, data, and all other Company Materials, information,
work product and written disclosures thereof, whether or not patentable or copyrightable.

          d. I agree that all Company Developments shall be the sole and exclusive property of the
Company. Unless the Company decides otherwise, the Company shall be the sole and exclusive owner
of all Rights in connection therewith. All copyright-protected Company Developments are and at all
times shall remain “work made for hire”. I hereby assign to the Company any and all of my Rights
to any Company Developments, absolutely and forever, throughout the world and for the full term of
each and every such Right, including renewal or extension of any such term.

          e. I agree to perform, during and after my employment, all acts deemed necessary or desirable
by the Company to permit and assist it, at the Company’s expense, in evidencing, perfecting,
obtaining, maintaining, defending and enforcing Rights and/or any assignments required hereunder in
any and all countries and otherwise effectuating the purposes of this Agreement. Such acts may
include, but are not limited to, execution of documents and assistance or cooperation in legal
proceedings or efforts to register, apply for, or otherwise obtain, prosecute or maintain Rights
relating to Proprietary Information, Company Materials or Company Developments. I hereby
irrevocably designate and appoint the Company and its duly authorized officers and agents, as my
agents and attorneys-in-fact to act for and in my behalf and instead of me, to execute and file any
documents and to do all other lawfully permitted acts to further the above purposes with the same
legal force and effect as if executed by me.

          f. Any assignment of copyright hereunder includes all rights of paternity, integrity,
disclosure and withdrawal and any other rights that may be known as or referred to as

Dec

“moral rights” (collectively “Moral Rights”). To the extent such Moral Rights cannot be
assigned under applicable law and to the extent the following is allowed by the laws in the various
countries where Moral Rights exist, I hereby waive such Moral Rights and consent to any action of
the Company that would violate such Moral Rights in the absence of such consent. I will confirm
any such waivers and consents from time to time as requested by the Company.

          g. I have attached hereto a complete list of all existing Developments to which I claim
ownership as of the date of this Agreement and that I desire to specifically clarify are not
subject to this Agreement, and I acknowledge and agree that such list is complete. If no such list
is attached to this Agreement, I represent that I have no such Developments at the time of signing
this Agreement.

          h. I represent that my performance of all the terms of this Agreement will not breach any
agreement to keep in confidence proprietary information acquired by me in confidence or in trust
prior to my employment by the Company. I have not entered into, and I agree I will not enter into,
any agreement either written or oral in conflict herewith or in conflict with my employment with
the Company. I also understand that I am prohibited from using or disclosing, in the course of my
employment with the Company, any proprietary information, trade secrets, or tangible property of
any other person or company, including prior employers, without the express authority to do so.

          i. I represent that any and all Developments that I may create under this Agreement will be
original and shall not defame the Company, its other employees, officers, directors, consultants or
agents or any third party or constitute a violation of the rights of privacy of the Company’s other
employees or any rights of any third party.

     5. In addition to any other remedies provided by law, if I breach this Agreement, the Company
shall be entitled to injunctive relief against me. In the event that the Company is required to
hire an attorney to enforce this Agreement or to defend against any claim because I have not
performed or fulfilled any of my obligations under this Agreement, the Company shall be entitled to
recover reasonable attorneys’ fees and other expenses in enforcing the obligation or defending
against the claim.

     6. I agree that this Agreement is not an employment contract and that I have the right to
resign and the Company has the right to terminate my employment at any time, for any reason, with
or without cause, subject to the provisions of any written employment agreement between the Company
and me.

     7. I agree that this Agreement does not purport to set forth all of the terms and conditions
of my employment, and that as an employee of the Company I have obligations to the Company which
are not set forth in this Agreement.

     8. I agree that my obligations under paragraphs 1, 2, 3, 4 and 5 of this Agreement shall
continue in effect after termination of my employment, regardless of the reason or reasons for
termination, and whether such termination is voluntary or involuntary on my part, and that the
Company is entitled to communicate my obligations under this Agreement to any future employer or
potential employer of mine.

remain in full force and effect and enforceable in accordance with its terms. The exclusion of any
provision from this Agreement shall not affect any other provision of this Agreement.

and this Agreement shall be binding upon me, my heirs, executors, assigns, and administrators and
shall inure to the benefit of the Company, its subsidiaries, successors and assigns.

FORM OF FOLEY &
LARDNER OPINION

     1. The Company is a corporation duly incorporated, validly existing and in active status under
the laws of the State of Wisconsin and has the corporate power and authority to execute and deliver
the Transaction Documents and to consummate the transactions contemplated thereby.

     2. The Company has duly authorized, executed and delivered the Transaction Documents and each
of the Transaction Documents constitutes the valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and other laws of general applicability relating to
or affecting creditors’ rights and to general equity principles.

     3. The Company’s authorized capital stock, immediately prior to the Closing, consists of the
following: (a) 80,000,000 shares of Common Stock, of which 12,086,237 shares are issued and
outstanding; (b) 20,000,000 shares of Cumulative Preferred Stock, of which (i) 500,000 shares are
designated Series A Convertible 12% Cumulative Preferred Stock (the “Series A Preferred Stock”), of
which none are issued or outstanding, (ii) 4,000,000 shares are designated Series B Preferred Stock
(the “Series B Preferred Stock”), of which 2,989,830 are issued and outstanding, and (iii)
2,000,000 shares are designated Series C Preferred Stock, 1,818,182 of which are issued and
outstanding. Each outstanding share of Common Stock, Series B Preferred Stock and Series C
Preferred Stock has been validly issued and is fully paid and non-assessable except to the extent
provided in Section 180.0622 of the Wisconsin Statutes. To our knowledge, there are no outstanding
options, warrants, conversion privileges, preemptive rights or other rights presently outstanding
to purchase any of the authorized but unissued capital stock of the Company, other than (1) 217,268
shares of Common Stock reserved for issuance under the Equity Incentive Plan, (2) 794,390 shares of
Common Stock reserved for issuance upon the exercise of warrants, (3) 2,989,830 shares of Common
Stock reserved for issuance upon the conversion of the Series B Preferred Stock, (4) 1,818,182
shares of Common Stock reserved for issuance upon the conversion of the Series C Preferred Stock,
(5) 2,360,802 shares of Common Stock reserved for issuance pursuant to the Agreement (subject to
adjustment in accordance with the terms thereof), (6) the preemptive rights of the Investors under
the Amended and Restated Investors’ Rights Agreement, and (7) the preemptive rights of the
Investors under the Amended and Restated First Offer and Co-Sale Agreement.

     4. The Notes have been duly authorized and, upon issuance and delivery of the shares of Common
Stock reserved for issuance in accordance with the terms of the Notes, such shares of Common Stock
will be validly issued, fully paid and nonassessable.

     5. No consent, approval, authorization or other action by or filing with any governmental
agency or instrumentality of the State of Wisconsin, the State of New
York or the United States of
America is required on the part of the Company for the execution and delivery of the Transaction
Documents or the consummation of the transactions contemplated thereby in accordance with the terms
thereof, except those already obtained or made or those required under Federal and state securities
laws to be made after the Closing.

     6. The execution and delivery of the Transaction Documents by the Company and the consummation
by the Company of the transactions contemplated thereby in accordance with the terms thereof do not
(i) violate any Wisconsin, New York or Federal statute, law, rule or regulation known to us to
which the Company is subject, (ii) breach the provisions of the Restated Articles or the Bylaws of
the Company, (iii) to our knowledge, breach the provisions of, or constitute a default under, any
of the agreements or instruments listed on the Schedule of Exceptions to the Agreement, except
where consent to such execution and delivery and such consummation is required pursuant to the
terms of such agreements or instruments, which consents, to our knowledge, have been obtained, or
(iv) violate or contravene any order, writ, judgment, decree, determination or award that
specifically names the Company.

     7. Based in part upon and assuming the accuracy of the representations and warranties of the
Purchasers set forth in Section 3 of the Agreement, it is not necessary in
connection with the issuance and sale of the Notes pursuant to the Agreement to register the
Notes under the Securities Act.

      As Representatives of the Underwriters named in the Underwriting Agreement

c/o Thomas Weisel Partners LLC

      Two International Place, 26th Flr

      Boston, MA 02110

Dear Sirs:

          As an inducement to the Underwriters to execute the Underwriting Agreement, pursuant to which
an offering will be made that is intended to result in the establishment of a public market for the
common stock (the “Securities”) of Orion Energy Systems, Inc., and any successor (by merger or
otherwise) thereto, (the “Company”), the undersigned hereby agrees that during the period specified
below (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge or
otherwise dispose of, directly or indirectly, any shares of Securities or securities convertible
into or exchangeable or exercisable for any shares of Securities, enter into a transaction which
would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in
whole or in part, any of the economic consequences of ownership of the Securities, whether any such
aforementioned transaction is to be settled by delivery of the Securities or such other securities,
in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or
disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in
each case, the prior written consent of Thomas Weisel Partners LLC (“TWP”). In addition, the
undersigned agrees that, without the prior written consent of TWP, it will not, during the Lock-Up
Period, make any demand for or exercise any right with respect to, the registration of any
Securities or any security convertible into or exercisable or exchangeable for the Securities;
provided, however that it is understood and agreed that this agreement will not apply to the
request to register, the registration or sale of any Securities that the undersigned registers or
sells to the underwriters in the initial public offering of the Company’s common stock.

          Any Securities received upon exercise of options granted to the undersigned or warrants held by the
undersigned or upon an automatic conversion of preferred stock held by the undersigned will also be
subject to this Agreement. Any Securities acquired by the undersigned in the open market or in any
issuer directed share program established in connection with the offering of the Securities will
not be subject to this Agreement. A transfer of Securities to a

1

 

family member or trust may be made, provided the transferee agrees to be bound in writing by the
terms of this Agreement prior to such transfer, such transfer shall not involve a disposition for
value and no filing by any party (donor, donee, transferor or transferee) under the Securities
Exchange Act of 1934, as amended, shall be required or shall be voluntarily made in connection with
such transfer (other than a filing on a Form 5 made after the expiration of the Lock-Up Period).

     The initial Lock-Up Period will commence on the date on which the Company files an initial
registration statement on Form S-1 with the Securities and Exchange Commission in connection with
the offering of the Securities (the “Commencement Date”) and will continue and include the date 180
days after the public offering date set forth on the final prospectus used to sell the Securities
(the “Public Offering Date”) pursuant to the Underwriting Agreement, to which you are or expect to
become, directly or indirectly, parties. If (1) during the last 17 days of the initial Lock-Up
Period, the Company releases earnings results or material news or a material event relating to the
Company occurs or (2) prior to the expiration of the initial Lock-Up Period, the Company announces
that it will release earnings results during the 16-day period beginning on the last day of the
initial Lock-Up Period, then in each case the Lock-Up Period will be extended until the expiration
of the 18-day period beginning on the date of release of the earnings results or the occurrence of
the material news or material event, unless TWP waives, in writing, such extension.

     The undersigned acknowledges and agrees that written notice of any extension of the Lock-Up
Period will be delivered by TWP to the Company (in accordance with Section 11 of the Underwriting
Agreement) and that any such notice properly delivered will be deemed to have been given to, and
received by, the undersigned. The undersigned further agrees that, prior to engaging in any
transaction or taking any other action that is subject to the terms of this Lock-Up Agreement
during the period from the Commencement Date to and including the 34th day following the
expiration of the initial Lock-Up Period, it will give notice thereof to the Company and will not
consummate such transaction or take any such action unless it has received written confirmation
from the Company that the Lock-Up Period (as may have been extended pursuant to the previous
paragraph) has expired.

     In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby
authorized to decline to make any transfer of shares of Securities if such transfer would
constitute a violation or breach of this Agreement.

     This Agreement shall be binding on the undersigned and the successors, heirs, personal
representatives and assigns of the undersigned. This Agreement shall lapse and become null and void
if the Public Offering Date shall not have occurred on or before March 3l, 2008. This agreement
shall be governed by, and construed in accordance with, the laws of the State of New York.
