knowledge of any executive officer of the Company (hereafter referred to as the  Companys
Knowledge ), currently threatened against the Company or any of its subsidiaries that questions the
validity of the Agreements or the right of the Company to enter into them, or to consummate the
transactions contemplated hereby or thereby, or that might result, either individually or in the
aggregate, in any Material Adverse Effect, or any change in the current equity ownership of the
Company, nor is the Company aware that there is any basis for the foregoing. Neither the Company
nor any of its subsidiaries is a party or subject to the provisions of any order, writ, injunction,
judgment or decree of any court or government agency or instrumentality. There is no action, suit,
proceeding or investigation by the Company or any of its subsidiaries currently pending or which
the Company or any of its subsidiaries intends to initiate.

trademarks, service marks, tradenames, copyrights, trade secrets, licenses, technology, information
and proprietary rights and processes necessary for its business as now conducted and, as presently
proposed to be conducted, without any conflict with, or known infringement of, the rights of
others. The Schedule of Exceptions contains a complete list of patents and pending patent
applications of the Company as well as trademarks, registered copyrights, and domain names owned by
the Company. The Company has not received any communications alleging that the Company has
violated or, by conducting its business as proposed, would violate any of the patents, trademarks,
service marks, tradenames, copyrights, trade secrets or other proprietary rights or processes of
any other person or entity. The Company is not aware that any of its 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 such employees best efforts to promote the interests of the Company or
that would conflict with the Companys business as presently conducted or proposed to be conducted.
Neither the execution or 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 best of 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 such employee 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.
 2.9 Proprietary Information of Third Parties. No third party has claimed by written notice to the
Company or, to the Companys Knowledge, has reason to claim that any person employed by, consulting
for or affiliated with the Company has (a) violated or may be violating, in connection with such
persons employment or affiliation with the Company, any of the terms or conditions of his or her
employment, noncompetition or nondisclosure agreement with such third party, (b) disclosed or may
be disclosing or utilized or may be utilizing, in connection with such persons employment or
affiliation with the Company, any trade secret or proprietary information or documentation of such
third party or (c) interfered or may be interfering, in connection with such persons employment or
affiliation with the Company, in the employment relationship between such third party and any of
its present or former employees. No third party has requested by written notice information from
the Company which suggests that such a claim might be contemplated. To the Companys Knowledge, no
person employed by, consulting for or affiliated with the Company has employed or proposes to
employ any trade secret or any information or documentation proprietary to any former employer, and
no person employed by, consulting for or affiliated with the Company has, to the Companys
Knowledge, violated any confidential relationship which such person may have had with any third
party, in connection with the development, manufacture or sale of any product or proposed product
of the Company or the development or sale of any service or proposed service of the Company, and
the Company has no reason to believe there will be any such employment or violation. To the
Companys Knowledge (without inquiry outside the ordinary course of business), neither the
execution or delivery of this Agreement nor the carrying on of the business of the Company by any
officer, director or key employee of the Company will 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 such person is obligated.
 2.10 Leasehold Interests. Each agreement to which the Company is a party under which it is a
lessee of any property, real or personal, is a valid and subsisting agreement, duly authorized and
entered into, without any default of the Company thereunder and, to the Companys Knowledge,
without any default thereunder




---



##### 



of any other party thereto, other than defaults that are not reasonably expected to have,
individually or in the aggregate, a Material Adverse Effect. No event has occurred and is
continuing which, with due notice or lapse of time or both, would constitute a default or event of
default by the Company or, to the Companys Knowledge, by any other party thereto under any such
lease or agreement, other than defaults that are not reasonably expected to have, individually or
in the aggregate, a Material Adverse Effect.
 2.11 Compliance with Other Instruments.
 (a) The Company is not in violation or default of any provisions of its Articles or
Bylaws or of any note, indenture, mortgage, lease (including equipment leases), agreement,
contract, purchase order or other instrument, document or agreement to which it is a party or by
which it is bound or, with respect to any injunction or decree of any court or any federal,
state, municipal or other governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, that specifically names the Company. To the best of the
Companys Knowledge, there exists no condition, event or act which after notice, lapse of time,
or both, would constitute a default by the Company under any of the foregoing. The execution,
delivery and performance of this Agreement and the consummation of the transactions contemplated
hereby do not and will not result in any such violation or be in conflict with or constitute,
with or without the passage of time or the giving of notice or both, either a default under, or
result in the creation of any lien, security interest, charge or encumbrance upon any of the
properties or assets of the Company under its Articles or Bylaws or under any note, indenture,
mortgage, lease (including equipment leases), agreement, contract, purchase order or other
instrument, document or agreement to which the Company is a party.
 (b) The Company has avoided every condition, and has not performed any act, the
occurrence of which would result in the Companys loss of any right granted under any license,
distribution agreement or other agreement.

Company and any of its officers, directors, affiliates, holders of any outstanding shares of any
class of the Companys capital stock, or any affiliate thereof other than those provided to
Purchaser.
 (b) Except for agreements explicitly contemplated by this Agreement, there are no
agreements, understandings, instruments, contracts or proposed transactions to which the Company
or any of its subsidiaries is a party or by which it is bound that involve (i) obligations
(contingent or otherwise) of, or payments to, the Company or any of its subsidiaries in excess
of, $25,000, (ii) the license of any patent, copyright, trade secret or other proprietary right
to or from the Company or any of its subsidiaries, (iii) the grant of rights to manufacture,

in any respect. The Company, and to the Companys Knowledge, each other party thereto has in
all material respects performed their respective obligations, and the Company has received no
notice of default by it and is not in default (with due notice or lapse of time or both) in any
material respect under any agreement, instrument, commitment, plan or arrangement to which the
Company is a party or by which it or its property may be bound, other than such nonperformance
or default that is not reasonably expected to have, individually or in the aggregate, a Material
Adverse Effect. The Company has no present expectation or intention of not fully performing all
the Companys obligations under each such agreement, instrument, commitment, plan or
arrangement, and to the Companys Knowledge there is no anticipated breach by any other party
thereto, other than such nonperformance or breach that is not reasonably expected to have,

dividends, or authorized or made any distribution upon or with respect to any class or series of
its capital stock, (ii) incurred any indebtedness for money borrowed or incurred any other

Purchasers have requested for deciding whether to acquire the Stock. No representation or warranty
of the Company contained in this Agreement (including the schedule of exceptions) and the exhibits
attached hereto or any certificate furnished or to be furnished to Purchasers at the Closing (when
read together) contains any untrue statement of a material fact or omits to state a material fact
necessary in order to make the statements contained herein or therein not misleading in light of
the circumstances under which they were made; provided that the foregoing does not limit any
knowledge or other qualifiers explicitly stated in such representations or warranties.
 2.14 No Conflict of Interest. The Company is not indebted, directly or indirectly, to any of its
stockholders, officers or directors or to their respective spouses or children, in any amount
whatsoever other than in connection with expenses or advances of expenses incurred in the ordinary
course of business or relocation expenses of employees. None of the Companys stockholders,
officers or directors, or any members of their immediate families, are, directly or indirectly,
indebted to the Company (other than in connection with purchases of the Companys stock) or, to the
Companys Knowledge, have any direct or indirect ownership interest in any firm or corporation with
which the Company is affiliated or with which the Company has a business relationship, or any firm
or corporation which competes with the Company except that officers, directors and/or stockholders
of the Company may own stock in (but not exceeding two percent of the outstanding capital stock of)
any publicly traded companies that may compete with the Company. To the Companys Knowledge, none
of the Companys officers or directors or any members of their immediate families are, directly or

capital shares of the Company.
 2.16 Title to Property and Assets. The Company owns its property and assets free and clear of all
mortgages, pledges, security interests, charges, claims, restrictions, liens, loans and
encumbrances, except such encumbrances and liens which arise in the ordinary course of business and
do not materially impair the Companys ownership or use of such property or assets and which do not
materially detract from the value of the property. With respect to the property and assets it
leases, the Company is in compliance with such leases and holds a valid leasehold interest free of
any liens, claims or encumbrances.

material respects. The Company has paid all taxes and other assessments due. Neither the Company
nor any of its present or former stockholders has ever filed an election pursuant to Section 1362
of the Internal Revenue Code of 1986, as amended (the  Code ), that the Company be taxed as an S
corporation. The Company has never had any tax deficiency proposed or assessed against it and has
not executed any waiver of any statute of limitations on the assessment or collection of any tax or
governmental charge. None of the Companys federal income tax returns and none of its state income
or franchise tax or sales or use tax returns has ever been audited by governmental authorities.
The Company has not incurred any taxes, assessments or governmental charges other than in the

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 the
Company. There is no strike or other labor dispute involving the Company pending, or to the
Companys Knowledge, threatened, which could have a Material Adverse Effect, nor is the Company
aware of any labor organization activity involving its employees. To the Companys Knowledge, no
officer or key employee of the Company, and no group of key employees of the Company, intends to
terminate their employment with the Company, 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
the Company is terminable at the will of the Company. The Company has complied in all material
respects with all applicable state and federal equal employment opportunity laws and with other

employment contract, deferred compensation agreement, bonus plan, incentive plan, profit sharing
plan, severance agreement, retirement agreement, or other employee compensation agreement, other
than those disclosed on the Schedule of Exceptions.
 2.20 Confidential Information and Invention Assignment Agreements. To the best of its knowledge,
the Company believes that each current and former employee, consultant, director and officer of the
Company has executed an agreement with the Company regarding confidentiality and proprietary
information. The Company is not aware that any of its current or former employees or consultants
is in violation thereof, and the Company will use its best efforts to prevent any such violation.
 2.21 Compliance with Law; Permits. The Company is not in violation of any applicable statute,
rule, regulation, order or restriction of any domestic or foreign government or any instrumentality
or agency thereof in respect of the conduct of its business or the ownership of its properties
which violation would constitute a Material Adverse Effect. The Company and each of its
subsidiaries has all franchises, permits, licenses and any similar authority necessary for the
conduct of its business, the lack of which could have a Material Adverse Effect. The Company is
not in default in any material respect under any of such franchises, permits, licenses or other
similar authority.

Purchasers. The copy of the minute books of the Company made available to Purchasers contain

representations set forth in Section 3 of this Agreement, the offer, sale and issuance of the Stock
and the Warrants as contemplated by this Agreement are, and will be as of the Closing, exempt from
the registration requirements of the Securities Act, and neither the Company nor any authorized
agent acting on its behalf will take any action hereafter that would cause the loss of such

broker, dealer or otherwise in connection with the offering or sale of the Stock, the Warrants or
any security of the Company similar to the Stock has: (a) offered the Stock or any such similar
security for sale to, or solicited any offer to buy the Stock or any such similar security from, or
otherwise approached or negotiated with respect thereto with, any person or persons, or (b) has
taken or will take any other action (including, without limitation, any offer, issuance or sale of
any security of the Company under circumstances which might require the integration of such
security with Stock under the Securities Act or the rules and regulations of the Securities and
Exchange Commission thereunder); in either case so as to subject the offering, issuance or sale of

maintained by, at the expense of or for the benefit of the Company. The Company maintains in full
force and effect such types and amounts of insurance issued by insurers of recognized
responsibility insuring it with respect to its respective business and properties, in such amounts
and against such losses as is customary for businesses similar to those of the Company. Each of
the insurance policies listed on Section 2.25 of the Schedule of Exceptions is in full force and
effect. The Company has not received any notice of cancellation, termination, or material increase
in premium with respect to any insurance policy listed on Section 2.25 of the Schedule of
Exceptions, and to the Companys Knowledge it will be able to renew each such policy as and when it
expires or to obtain similar coverage from similar insurers as may be necessary to continue its
business, without a significant increase in cost, except where any inability to so renew a policy
or obtain similar coverage will not have a Material Adverse Effect.

statement of cash flows, including notes thereto) as at and for the year ended December 31, 2006,

distributing the same. By executing this Agreement, the Purchaser further represents that the

qualification requirements is available. The Purchaser acknowledges that the Company has no
obligation to register or qualify the Securities for resale except as set forth in the Investor
Rights Agreement. The Purchaser 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 Purchasers control, and which the Company is
under no obligation and may not be able to satisfy.

of the following legends:

SECURITIES ACT OF 1933, AS AMENDED AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO,
