for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) such
Buyer shall have delivered to the Company an opinion, in generally acceptable form, of counsel
selected by the Buyer and reasonably satisfactory to the Company, to the effect that such Notes to

can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated under the 1933
Act (or a successor rule thereto) (collectively, “Rule 144”); (ii) any sale of the Notes may
require compliance with some other exemption under the 1933 Act or the rules and regulations of the

bear any legend that is required by the “blue sky” laws of any state and a restrictive legend in
substantially the following form (and a stop-transfer order may be placed against transfer of such
stock certificates):

3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. 

The Company represents and warrants to each of the Buyers that:

(a) Organization and Qualification. The Company and its “Subsidiaries” (which for
purposes of this Agreement means any entity of which the Company, directly or indirectly, owns or
controls a majority of the shares of capital stock or holds or controls a majority of all equity or
similar interests then outstanding) are entities duly organized and validly existing in good
standing under the laws of the jurisdiction in which they are formed, and have the requisite power
and authority to own their properties and to carry on their business as now being conducted. Each
of the Company and its Subsidiaries is duly qualified as a foreign entity to do business and is in
good standing in every jurisdiction in which its ownership of property or the nature of the
business conducted by it makes such qualification necessary, except to the extent that the failure
to be so qualified or be in good standing would not reasonably be expected to have a Material
Adverse Effect. As used in this Agreement, “Material Adverse Effect” means any material adverse
effect on the business, properties, assets, operations, results of operations or condition
(financial or otherwise) of the Company and its Subsidiaries, taken as a whole, or on the
transactions contemplated hereby and the other Transaction Documents (as defined below) or by the
agreements and instruments to be entered into in connection herewith or therewith, or on the
authority or ability of the Company to perform its obligations under the Transaction Documents to
which it is a party. The Company has no Subsidiaries except as set forth on Schedule 3(a),
all of which Subsidiaries are wholly-owned by the Company, either directly or indirectly.

(b) Authorization; Enforcement; Validity. The Company has the requisite power and
authority to enter into and perform its obligations under this Agreement and the Notes (together,
the “Transaction Documents”). The execution and delivery of the Transaction Documents to which the
Company is a party and the consummation by the Company of the transactions contemplated hereby and
thereby have been duly authorized by the Company’s Board of Directors and no further filing,
consent or authorization is required by the Company, its Board of Directors or its stockholders.
This Agreement and the other Transaction Documents to which the Company is a party have been duly
executed and delivered by the Company, and constitute or, in the case of the Notes, will
constitute, the legal, valid and binding obligations of the Company, enforceable against the
Company in accordance with their respective terms, except as such enforceability may be limited by
general principles of equity or applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance, liquidation or similar laws relating to, or affecting generally, the
enforcement of applicable creditors’ rights and remedies.

(c) Offer of Notes. The offer by the Company of the Notes is exempt from registration
under the 1933 Act.

(d) No Conflicts. The execution, delivery and performance of the Transaction
Documents to which the Company is a party and the consummation by the Company of the transactions
contemplated hereby and thereby will not (i) result in a violation of any articles of
incorporation, certificate of formation, any certificate of designations or other constituent
documents of the Company or any of its Subsidiaries, any capital stock of the Company or any of its
Subsidiaries, or the bylaws of the Company or any of its Subsidiaries or (ii) conflict with, or
constitute a default (or an event which with notice or lapse of time or both would become a
default) under, or give to others any rights of termination, amendment, acceleration or
cancellation of, any agreement, indenture or instrument to which the Company or any of its
Subsidiaries is a party, or (iii) result in a violation of any law, rule, regulation, order,
judgment or decree (including federal and state securities laws and regulations) applicable to the
Company or any of its Subsidiaries or by which any property or asset of the Company or any of its
Subsidiaries is bound or affected.

(e) Consents. The Company is not required to obtain any consent, authorization or
order of, or make any filing or registration with, any court, governmental agency or any regulatory
or self-regulatory agency or any other Person in order for it to execute, deliver or perform any of
its obligations under or contemplated by the Transaction Documents to which it is a party, in each
case in accordance with the terms hereof or thereof, other than any filing required to be made by
the Company following the Closing with the SEC and related state securities law filings.

(f) Acknowledgment Regarding Buyer’s Purchase of Notes. The Company acknowledges and
agrees that each Buyer is acting solely in the capacity of an arm’s length purchaser with respect
to the Transaction Documents and the transactions contemplated hereby and thereby and that no Buyer
is (i) an officer or director of the Company, (ii) to the knowledge of the Company, an “affiliate”
of the Company (as defined in Rule 144) or (iii) to the knowledge of the Company, a “beneficial
owner” of more than 10% of the shares of Common Stock (as defined for purposes of Rule 13d-3 of the
Securities Exchange Act of 1934, as amended (the “1934 Act”)). The Company further acknowledges
that no Buyer is acting as a financial advisor or fiduciary of the Company (or in any similar
capacity) with respect to the Transaction Documents and the transactions contemplated hereby and
thereby, and any advice given by a Buyer or any of its representatives or agents in connection with
the Transaction Documents and the transactions contemplated hereby and thereby is merely incidental
to such Buyer’s purchase of the Notes. The Company further represents to each Buyer that the
decision of the Company to enter into the Transaction Documents has been based solely on the
independent evaluation by the Company and its representatives.

(g) No General Solicitation; Placement Agent’s Fees. None of the Company, any of its
affiliates, or any Person acting on its or their behalf, has engaged in any form of general
solicitation or general advertising (within the meaning of Regulation D of the 1933 Act) in
connection with the offer or sale of the Notes. The Company shall be responsible for the payment
of any placement agent’s fees, financial advisory fees, or brokers’ commissions (other than for
persons engaged by any Buyer or its investment advisor) relating to or arising out of the
transactions contemplated hereby. The Company shall pay, and hold each Buyer harmless against, any
liability, loss or expense (including, without limitation, attorney’s fees and out-of-pocket
expenses) arising in connection with any such claim. The Company acknowledges that it has engaged
the placement agent set forth on Schedule 3(g) in connection with the sale of the Notes.
The Company has not otherwise engaged any placement agent or other agent in connection with the
sale of the Notes.

(h) No Integrated Offering. None of the Company, its Subsidiaries, any of their
affiliates, or any Person (as defined in Section 3(o) hereof) acting on their behalf has, directly
or indirectly, made any offers or sales of any security or solicited any offers to buy any
security, under circumstances that would require registration of any of the Notes under the 1933
Act or cause this offering of the Notes to be integrated with prior offerings by the Company for
purposes of the 1933 Act.

(i) SEC Documents, Financial Statements.

(i) Since January 1, 2003, the Company has timely filed (within applicable extension periods)
all reports, schedules, forms, statements and other documents required to be filed by it with the
SEC pursuant to the reporting requirements of the 1934 Act (all of the foregoing filed prior to the
date hereof included therein and financial statements and financial statement schedules thereto and
documents incorporated by reference therein, the “SEC Documents”). For purposes of this Agreement,
“SEC Documents” includes the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ended
March 31, 2006, a draft of which has been provided to the Buyers on the date hereof and will be
filed with the SEC in substantially the form provided to the Buyers (the “Draft 10-Q”). The
Company has delivered to the Buyer true and complete copies of the SEC Documents, or such documents
are available on EDGAR. As of their respective dates, the SEC Documents complied in all material
respects with the requirements of the 1934 Act or the Securities Act, as the case may be, and the
rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none
of the SEC Documents, at the time they were filed with the SEC, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which they were made, not
misleading. None of the statements made in any such SEC Documents is, or has been, required to be
amended or updated under applicable law (except for such statements as have been amended or updated
in subsequent filings made prior to the date hereof).

(ii) As of their respective dates, the financial statements of the Company included in the SEC
Documents complied as to form in all material respects with applicable accounting requirements and
the published rules and regulations of the SEC applicable with respect thereto. Such financial
statements have been prepared in accordance with U.S. generally accepted accounting principles
(“GAAP”), consistently applied, during the periods involved (except as may be otherwise indicated
in such financial statements or the notes thereto or, in the case of unaudited interim statements,
to the extent they may not include footnotes or may be condensed or summary statements) and fairly
present in all material respects the consolidated financial position of the Company and its
consolidated Subsidiaries as of the dates thereof and the consolidated results of their operations
and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal,
immaterial year-end audit adjustments). Except as set forth in the financial statements of the
Company (and in the footnotes thereto) included in the Select SEC Documents (as defined below), the
Company has no liabilities, contingent or otherwise, other than (A) liabilities incurred in the
ordinary course of business subsequent to the date of such financial statements and (B) obligations
under contracts and commitments incurred in the ordinary course of business and not required under
GAAP to be reflected in such financial statements, which liabilities and obligations referred to in
clauses (A) and (B), individually or in the aggregate would not reasonably be expected to have a
Material Adverse Effect.

(iii) To the extent required by the rules and regulations of the SEC applicable thereto, the
Select SEC Documents contain a complete and accurate list of all material undischarged written or
oral contracts, agreements, leases or other instruments to which the Company or any Subsidiary is a
party or by which the Company or any Subsidiary is bound or to which any of the properties or
assets of the Company or any Subsidiary is subject (each, a “Material Contract”). Except as set
forth in the Select SEC Documents, neither the Company, nor any of its Subsidiaries is in breach or
violation of any Material Contract, which breach or violation would have a Material Adverse Effect.
For purposes of this Agreement, “Select SEC Documents” means the Company’s (A) Annual Report on
Form 10-K for the fiscal year ended December 31, 2005 (the “2005 Annual Report”), (B) Draft 10-Q
and (C) Current Reports on Form 8-K filed since December 31, 2005.

(j) Absence of Certain Changes. Except as set forth in the Select SEC Documents,
since December 31, 2005, there has been no material adverse change and no material adverse
development in the business, properties, operations, financial condition or results of operations
of the Company and its Subsidiaries, taken as a whole. The Company does not currently expect to
take any steps to seek protection pursuant to any bankruptcy or receivership law, nor does the
Company or any of its Subsidiaries have any knowledge or reason to believe that its creditors
intend to initiate involuntary bankruptcy proceedings with respect to the Company or any of its
Subsidiaries.

(k) Conduct of Business; Regulatory Permits. Neither the Company nor its Subsidiaries
is in violation of any term of or in default under its articles of incorporation, certificate of
formation, any certificate of designations or other constituent documents or its bylaws. Neither
the Company nor any of its Subsidiaries is in violation of any judgment, decree or order or any
statute, ordinance, rule or regulation applicable to the Company or its Subsidiaries, except for
possible violations which would not, individually or in the aggregate, have a Material Adverse
Effect. The Company and its Subsidiaries possess all certificates, authorizations and permits
issued by the appropriate regulatory authorities necessary to conduct their respective businesses,
except where the failure to possess such certificates, authorizations or permits would not have,
individually or in the aggregate, a Material Adverse Effect, and neither the Company nor any such
Subsidiary has received any notice of proceedings relating to the revocation or modification of any
such certificate, authorization or permit.

(l) Foreign Corrupt Practices. Neither the Company, nor any of its Subsidiaries, nor,
to the Company’s knowledge, any director, officer, agent or employee acting on behalf of the
Company or any of its Subsidiaries has, in the course of its actions for, or on behalf of, the
Company (i) used any corporate funds for any unlawful contribution, gift, entertainment or other
unlawful expenses relating to political activity; (ii) made any direct or indirect unlawful payment
to any foreign or domestic government official or employee from corporate funds; (iii) violated or
is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended; or

(m) Transactions With Affiliates. Except as set forth in Schedule 3(m)
hereto, none of the officers, directors or employees of the Company is presently a party to any
transaction with the Company or any of its Subsidiaries (other than for ordinary course services as
employees, officers or directors), including any contract, agreement or other arrangement providing
for the furnishing of services to or by, providing for rental of real or personal property to or
from, or otherwise requiring payments to or from any such officer, director or employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in which any such
officer, director, or employee has a substantial interest or is an officer, director, trustee or
partner.

(n) Equity Capitalization. As of May 1, 2006, the authorized capital stock of the
Company consists of (i) 100,000,000 shares of common stock, $.01 par value (the “Common Stock”),
54,740,296 of which are issued and outstanding and (ii) 10,000,000 shares of preferred stock, $.01
par value, none of which is issued and outstanding. All of such outstanding shares have been
validly issued and are fully paid and nonassessable. Except as disclosed in Schedule 3(n):
(i) none of the Company’s share capital is subject to preemptive rights or any other similar rights
or any liens or encumbrances suffered or permitted by the Company; (ii) there are no outstanding
debt securities, notes, credit agreements, credit facilities or other agreements, documents or
instruments evidencing Indebtedness (as defined in the Notes) of the Company or any of its
Subsidiaries or by which the Company or any of its Subsidiaries is or may become bound; (iii) there
are no financing statements securing obligations in any material amounts, either singly or in the
aggregate, filed in connection with the Company; and (iv) there are no outstanding securities or
instruments of the Company or any of its Subsidiaries which contain any redemption or similar
provisions, and there are no contracts, commitments, understandings or arrangements by which the
Company or any of its Subsidiaries is or may become bound to redeem a security of the Company or
any of its Subsidiaries. The Company has furnished to the Buyer true, correct and complete copies
of the Company’s Articles of Incorporation, as amended and as in effect on the date hereof (the
"Articles of Incorporation”), the Company’s Bylaws, as amended and as in effect on the date hereof
(the “Bylaws”), and all agreements of the Company relating to any Indebtedness (as defined in the
Notes) of the Company.

(o) Indebtedness and Other Contracts. Except as disclosed in Schedule 3(o),
neither the Company nor any of its Subsidiaries (i) has any outstanding Indebtedness, (ii) is in
violation of any term of or in default under any contract, agreement or instrument relating to any
Indebtedness, except where such violations and defaults would not result, individually or in the
aggregate, in a Material Adverse Effect, or (iii) is a party to any contract, agreement or
instrument relating to any Indebtedness, the performance of which, in the judgment of the Company’s
officers, has or is expected to have a Material Adverse Effect. For purposes of this Agreement,
"Person” means an individual, a limited liability company, a partnership, a joint venture, a
corporation, a trust, an unincorporated organization or a government or any department or agency
thereof.

(p) Absence of Litigation. Except as set forth in the SEC Documents, there is no
action, suit, proceeding, inquiry or investigation that is material, individually or in the
aggregate, before or by, any court, public board, government agency, self-regulatory organization
or body pending or, to the knowledge of the Company, threatened against or affecting the Company,
any of the Company’s Subsidiaries, any of the Company’s or the Company’s Subsidiaries’ assets, or
any of the Company’s or the Company’s Subsidiaries’ officers or directors.

(q) Insurance. The Company and each of its Subsidiaries are insured by insurers of
recognized financial responsibility against such losses and risks and in such amounts as management
of the Company believes to be prudent and customary in the businesses in which the Company and its
Subsidiaries are engaged. Except as set forth on Schedule 3(q), neither the Company nor
any such Subsidiary has been refused any insurance coverage sought or applied for and neither the
Company nor any such Subsidiary has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue its business at a cost that would not have a
Material Adverse Effect.

(r) Employee Relations.

(i) Neither the Company nor any of its Subsidiaries is a party to any collective bargaining
agreement or employs any member of a union. The Company and its Subsidiaries believe that their
relations with their employees are good. None of the Company’s executive officers (the “Executive
Officers”) has notified the Company that such officer intends to leave the Company or otherwise
terminate such officer’s employment with the Company. No Executive Officer, to the knowledge of
the Company, is, or is expected to be, in violation of any material term of any employment
contract, confidentiality, disclosure or proprietary information agreement, non-competition
agreement, or any other contract or agreement or any restrictive covenant, and the continued
employment of each Executive Officer does not subject the Company or any of its Subsidiaries to any
liability with respect to any of the foregoing matters.

(ii) The Company and its Subsidiaries are in compliance with all federal, state, local and
foreign laws and regulations respecting labor, employment and employment practices and benefits,
terms and conditions of employment and wages and hours, except where failure to be in compliance
would not, either individually or in the aggregate, reasonably be expected to result in a Material
Adverse Effect.

(s) Title. Except as set forth on Schedule 3(s), the Company and its
Subsidiaries have good and marketable title in fee simple to all real property and good and
marketable title to all personal property owned by them which is material to the business of the
Company and its Subsidiaries, in each case free and clear of all liens and encumbrances except for
the blanket lien securing the Senior Indebtedness and such as do not materially affect the value of
such property and do not interfere with the use made and proposed to be made of such property by
the Company and any of its Subsidiaries. Any real property and facilities held under lease by the
Company and any of its Subsidiaries are held by them under valid, subsisting and enforceable leases
with such exceptions as are not material and do not interfere with the use made and proposed to be
made of such property and buildings by the Company and its Subsidiaries.

(t) Intellectual Property Rights. The Company and its Subsidiaries own or possess
adequate rights or licenses to use all trademarks, service marks, and all applications and
registrations therefor, trade names, patents, patent rights, copyrights, original works of
authorship, inventions, licenses, approvals, governmental authorizations, trade secrets and other
intellectual property rights (“Intellectual Property Rights”) necessary to conduct their respective
businesses as now conducted. None of the Company’s Intellectual Property Rights have expired or
terminated, or are expected to expire or terminate, within three years from the date of this
Agreement. The Company does not have any knowledge of any infringement by the Company or its
Subsidiaries of Intellectual Property Rights of others. Except as set forth on Schedule
3(t), there is no claim, action or proceeding being made or brought, or to the knowledge of the
Company, being threatened, against the Company or its Subsidiaries regarding its Intellectual
Property Rights. The Company is unaware of any facts or circumstances which might give rise to any
of the foregoing infringements or claims, actions or proceedings. The Company and its Subsidiaries
have taken reasonable security measures to protect the secrecy, confidentiality and value of all of
their Intellectual Property Rights.

(u) Environmental Laws. The Company and its Subsidiaries (i) are in compliance with
any and all applicable Environmental Laws (as hereinafter defined), (ii) have received all permits,
licenses or other approvals required of them under applicable Environmental Laws to conduct their
respective businesses and (iii) are in compliance with all terms and conditions of any such permit,
license or approval where, in each of the foregoing clauses (i), (ii) and (iii), the failure to so
comply could be reasonably expected to have, individually or in the aggregate, a Material Adverse
Effect. The term “Environmental Laws” means all federal, state, local or foreign laws relating to
pollution or protection of human health or the environment (including, without limitation, ambient
air, surface water, groundwater, land surface or subsurface strata), including, without limitation,
laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants,
contaminants, or toxic or hazardous substances or wastes (collectively, “Hazardous Materials”) into
the environment, or otherwise relating to the manufacture, processing, distribution, use,
treatment, storage, disposal, transport or handling of Hazardous Materials, as well as all
authorizations, codes, decrees, demands or demand letters, injunctions, judgments, licenses,
notices or notice letters, orders, permits, plans or regulations issued, entered, promulgated or
approved thereunder.

(v) Subsidiary Rights. Except as set forth in Schedule 3(v), the Company or
one of its Subsidiaries has the unrestricted right to vote, and (subject to limitations imposed by
applicable law) to receive dividends and distributions on, all capital securities of its
Subsidiaries as owned by the Company or each Subsidiary.

(w) Tax Status. Except as set forth on Schedule 3(w), the Company and each of
its Subsidiaries (i) has made or filed all foreign, federal and state income and all other tax
returns, reports and declarations required by any jurisdiction to which it is subject, (ii) has
paid all taxes and other governmental assessments and charges that are material in amount, shown or
determined to be due on such returns, reports and declarations, except those being contested in
good faith and (iii) has set aside on its books provision reasonably adequate for the payment of
all taxes for periods subsequent to the periods to which such returns, reports or declarations
apply. There are no unpaid taxes in any material amount claimed to be due by the taxing authority
of any jurisdiction, and the officers of the Company know of no basis for any such claim. No liens
have been filed and no claims are being asserted by or against the Company or any of its
Subsidiaries with respect to any taxes (other than liens for taxes not yet due and payable).
Neither the Company nor it Subsidiaries has received notice of assessment or proposed assessment of
any taxes claimed to be owed by it or any other Person on its behalf. Except as disclosed on
Schedule 3(w), neither the Company nor any Subsidiary is a party to any tax sharing or tax
indemnity agreement or any other agreement of a similar nature that remains in effect. Each of the
Company and its Subsidiaries has complied in all material respects with all applicable legal
requirements relating to the payment and withholding of taxes and, within the time and in the
manner prescribed by law, has withheld from wages, fees and other payments and paid over to the
proper governmental or regulatory authorities all amounts required.

(x) Internal Accounting Controls. The Company and each of its Subsidiaries maintain a
system of internal accounting controls sufficient to provide reasonable assurance that (i)
transactions are executed in accordance with management’s general or specific authorizations, (ii)
transactions are recorded as necessary to permit preparation of financial statements in conformity
with U.S. GAAP and to maintain asset and liability accountability, (iii) access to assets or
incurrence of liabilities is permitted only in accordance with management’s general or specific
authorization and (iv) the recorded accountability for assets and liabilities is compared with the
existing assets and liabilities at reasonable intervals and appropriate action is taken with
respect to any difference. The Company has established disclosure controls and procedures (as
defined in 1934 Act Rules 13a-15 and 15d-15) for the Company and designed such disclosures controls
and procedures to ensure that material information relating to the Company, including its
Subsidiaries, is made known to the certifying officers by others within those entities,
particularly during the period in which the Company’s Annual Report on Form 10-K or Quarterly
Report on Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers have
evaluated the effectiveness of the Company’s controls and procedures as of a date within 90 days
prior to the filing date of the 2005 Annual Report and the Company’s most recently filed Quarterly
Report on Form 10-Q (each such date, an “Evaluation Date”). The Company presented in the 2005
Annual Report and its most recently filed Quarterly Report on Form 10-Q the conclusions of the
certifying officers about the effectiveness of the disclosure controls and procedures based on
their evaluations as of the respective Evaluation Date. Since the Evaluation Date for the 2005
Annual Report, there have been no significant changes in the Company’s “internal controls” (as such
term is defined in Item 307(b) of Regulation S-K under the 1934 Act) or, to the Company’s
knowledge, in other factors that could significantly affect the Company’s internal controls.

(y) Ranking of Notes. Except for the Senior Indebtedness (as defined in the Notes),
no Indebtedness of the Company or any of its Subsidiaries, at the Closing, will be senior to or
pari passu with the Notes by the Company in right of payment, whether with respect of payment or
redemptions, interest, damages or upon liquidation or dissolution or otherwise, excluding (i) the
obligations of the Company or its Subsidiaries under any lease of real or personal property by such
Person as lessee which is required under GAAP to be capitalized on such Person’s balance sheet and
(ii) Indebtedness permitted by clause (v) of the definition of “Permitted Lien” set forth in the
Notes.

(z) Solvency. Based on the financial condition of the Company as of the Closing Date,
(i) the fair saleable value of the Company’s assets exceeds the amount that will be required to be
paid on or in respect of the Company’s existing debts and other liabilities (including known
contingent liabilities) as they mature; (ii) the Company’s assets do not constitute unreasonably
small capital to carry on its business for the current fiscal year as now conducted and as proposed
to be conducted including its capital needs taking into account the particular capital requirements
of the business conducted by the Company, and projected capital requirements and capital
availability thereof; and (iii) the current cash flow of the Company, together with the proceeds
the Company would receive, were it to liquidate all of its assets, after taking into account all
anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its debt
when such amounts are required to be paid. The Company does not intend to incur debts beyond its
ability to pay such debts as they mature (taking into account the timing and amounts of cash to be
payable on or in respect of its debt).

(aa) Listing. The Common Stock is currently listed for trading on the Nasdaq Capital
Market. Except as set forth on Schedule 3(aa), the Company is not in violation of the
listing requirements of the Capital Market and the Company does not presently reasonably anticipate
that the Common Stock will be delisted by the Nasdaq Capital Market during the one-year period
immediately following the Closing. Except as set forth on Schedule 3(aa), the Company has
not received any notice regarding the possible delisting of the Common Stock from the Nasdaq
Capital Market.

(bb) Disclosure. All disclosure, oral or written, provided to the Buyers regarding
the Company, its business and the transactions contemplated hereby, including the Schedules to this
Agreement, furnished by or on behalf of the Company, taken as a whole, is true and correct and does
not contain any untrue statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in the light of the circumstances under which they were
made, not misleading.

4. COVENANTS.

(a) Best Efforts. Each party shall use its best efforts timely to satisfy each of the
conditions to be satisfied by it as provided in Sections 6 and 7 of this Agreement.

(b) Original Issue Discount. Each Buyer acknowledges that the Notes are being issued
with original issue discount as that term is used by Sections 1272, 1273 and 1275 of the Internal
Revenue Code of 1986, as amended and as set forth on the face of the Notes. Each Buyer hereby
agrees, to the extent required by law, to prepare all books, records, and filings as to the U.S.
tax treatment of the Notes in a manner consistent with the Company’s U.S. income tax information
reporting delivered to each Buyer with respect to the Notes.

(c) Form D and Blue Sky. The Company shall, on or before the Closing Date, take such
action as the Company shall reasonably determine is necessary in order to obtain an exemption for
or to qualify the Notes for sale to the Buyers at the Closing pursuant to this Agreement under
applicable United States federal securities laws and securities or “Blue Sky” laws of the states of
the United States (or to obtain an exemption from such qualification), and shall provide evidence
of any such action so taken to the Buyers on or prior to the Closing Date. Without limiting the
foregoing, the Company agrees to file a Form D with respect to the Notes as required under
Regulation D of the 1933 Act and to provide a copy thereof to each Buyer promptly after such
filing.

(d) Use of Proceeds. The Company shall use the proceeds from the sale of the Notes
for general working capital purposes subject to the following limitations: (i) the Company shall
not use any of the proceeds from the sale of the Notes to pay any settlement on account of
litigation pending against the Company or to satisfy any judgment entered against the Company and
(ii) the Company may not use any of the proceeds from the sale of the Notes to make payments on
account of the Senior Indebtedness (as defined in the Notes), excluding any payment or portion
thereof required to be paid in cash in accordance with the terms of the Senior Indebtedness;
provided, however, that if the Company consummates the reverse stock split (the
"Reverse Stock Split”) described in its Definitive Proxy Statement on Schedule 14A filed with the
SEC on April 12, 2006, in connection with the Company’s 2006 annual meeting of shareholders, the
Company may use up to $350,000 of the proceeds of the Notes to pay in cash the first amortization
payment due under the Senior Indebtedness after the Reverse Stock Split. Notwithstanding the
foregoing, the Company shall be permitted to use the proceeds from the sale of the Notes for
payments made pursuant to the Settlement Agreement and Release dated May 9, 2006, between
CombineNet, Inc. and the Company and for the payment described on Schedule 4(d).

(e) Sale of Assets. So long as the Notes are outstanding, the Company shall not, and
the Company shall not permit any of its Subsidiaries to, make or permit to be made any transfer of
any assets other than the sale of inventory in the ordinary course of business and the sale of
obsolete or unnecessary equipment without the express written consent of the Buyers

(f) Nature of Business. So long as the Notes are outstanding, the Company shall not,
and the Company shall not permit any of its Subsidiaries to, make any change in the principal
nature of its or their business.

(g) Reporting Status. The Company shall use its best efforts to timely file all
reports required to be filed with the SEC pursuant to the 1934 Act, and the Company shall not
terminate its status as an issuer required to file reports under the 1934 Act even if the 1934 Act
or the rules and regulations thereunder would otherwise permit such termination.

(h) Financial Information.

(i) The Company agrees to send the following to the registered holders of the Notes (each, a
"Holder”), so long as any Notes are outstanding, unless the following are filed with the SEC
through EDGAR and are available to the public through the EDGAR system, (i) within one Business Day
after the filing thereof with the SEC: (A) a copy of its Annual Reports on Form 10-K or 10-KSB; (B)
any interim reports or any consolidated balance sheets, income statements, stockholders’ equity
statements and/or cash flow statements for any period other than annual; (C) any Current Reports on
Form 8-K; and (D) any registration statements (other than on Form S-8) or amendments filed pursuant
to the 1933 Act and (ii) copies of any notices and other information made available or given to the
stockholders of the Company generally, contemporaneously with the making available or giving
thereof to the stockholders.

(ii) In the event that the Company is no longer required to file reports under the 1934 Act,
the Company agrees to send the following to the registered holders of the Notes, so long as any
Notes are outstanding:

(A) As soon as available and in any event within 120 days after the end of each fiscal year of
the Company, a balance sheet of the Company, as of the end of such fiscal year and the related
statements of income, prepared in accordance with generally accepted accounting principles; and

(B) As soon as practicable, but in any event within 60 days after the end of the first three
quarters of each fiscal year of the Company, an unaudited profit or loss statement of the Company,
schedule as to the sources and application of funds for such fiscal quarter and an unaudited
balance sheet of the Company.

(i) Fees. The Company, on the one hand, and the Buyers, on the other hand, shall each
bear their own legal fees and other expenses with respect to the transactions contemplated by this
Agreement, provided that the Company shall pay the reasonable legal fees of the Buyers not
to exceed $33,000 in the aggregate upon Closing; provided further, that in the
event that this Agreement is terminated prior to Closing, the Company shall pay the reasonable
legal fees of the Buyers not to exceed $15,000 in the aggregate.

(j) Pledge of Notes. The Company acknowledges and agrees that the Notes may be
pledged by a Holder in connection with a bona fide margin agreement or other loan or financing
arrangement that is secured by the Notes. The pledge of Notes shall not be deemed to be a
transfer, sale or assignment of the Notes hereunder, and no Holder effecting a pledge of Notes
shall be required to provide the Company with any notice thereof or otherwise make any delivery to
the Company pursuant to this Agreement or any other Transaction Document, including, without
limitation, Section 2(f) hereof; provided that an Holder and its pledgee shall be required
to comply with the provisions of Section 2(f) hereof in order to effect a sale, transfer or
assignment of Notes to such pledgee. The Company hereby agrees to execute and deliver such
documentation as a pledgee of the Notes may reasonably request in connection with a pledge of the
Notes to such pledgee by a Holder.

(k) Disclosure of Transactions and Other Material Information. On or before 8:30
a.m., New York Time, on the second Business Day following the Closing Date, the Company shall file
a Current Report on Form 8-K, in each case, describing the terms of the transactions contemplated
by the Transaction Documents in the form required by the 1934 Act and attaching the material
Transaction Documents as exhibits to such filing (including all attachments, the “8-K Filing”).
Subject to the foregoing, neither the Company, nor any Buyer shall issue any press releases or any
other public statements with respect to the transactions contemplated hereby; provided,
however, that the Company shall be entitled, without the prior approval of any Buyer, to
make any press release or other public disclosure with respect to such transactions (i) in
substantial conformity with the 8-K Filing and contemporaneously therewith and (ii) as is required
by applicable law and regulations (provided that in the case of clause (i) the Holders shall be
consulted by the Company in connection with and given an opportunity to review and comment on any
such press release or other public disclosure prior to its release). Notwithstanding the
foregoing, the Company shall not publicly disclose the name of any Buyer, or include the name of
any Buyer in any filing with the SEC or any regulatory agency or the Nasdaq Capital Market or other
stock exchange or automated quotation system upon which the Company’s shares of common stock are
traded, including, without limitation, any and all discounted issuance rules, if applicable,
without the prior written consent of such Buyer, except (i) for disclosure thereof in the 8-K
Filing or (ii) as required by law or regulations of the Nasdaq Capital Market or other stock
exchange or automatic quotation system upon which the Company’s common stock is then traded or any
order of any court or other governmental agency, in which case the Company shall provide such Buyer
with prior notice of such disclosure and the opportunity to review and comment on such disclosure.

(l) Incurrence of Indebtedness. So long as this Note is outstanding, the Company
shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly,
incur or guarantee, assume or suffer to exist any Indebtedness, other than (i) the Indebtedness
evidenced by the Notes and (ii) Permitted Indebtedness (as defined in the Notes).

(m) Existence of Liens. So long as this Note is outstanding, the Company shall not,
and the Company shall not permit any of its Subsidiaries to, directly or indirectly, allow or
suffer to exist any Liens (as defined in the Notes) other than Permitted Liens (as defined in the
Notes).

(n) Restricted Payments. The Company shall not, and the Company shall not permit any
of its Subsidiaries to, directly or indirectly, (i) redeem, defease, repurchase, repay or make any
payments in respect of, by the payment of cash or cash equivalents (in whole or in part, whether by
way of open market purchases, tender offers, private transactions or otherwise), all or any portion
of any Permitted Indebtedness (other than the Senior Indebtedness), whether by way of payment in
respect of principal of (or premium, if any) or interest on, such Permitted Indebtedness (as
defined in the Notes) if at the time such payment is due or is otherwise made or, after giving
effect to such payment, an event constituting, or that with the passage of time and without being
cured would constitute, an Event of Default has occurred and is continuing, (ii) declare or pay any
cash dividend or distribution on the Common Stock, (iii) redeem, repurchase or otherwise acquire or
retire for value any shares of Common Stock (iv) pay any settlement on account of litigation
pending against the Company or to satisfy any judgment entered against the Company or (v) make
payments on account of the Senior Indebtedness, excluding any payment or portion thereof required
to be paid in cash in accordance with the terms of the Senior Indebtedness; provided,
however, that if the Company consummates the Reverse Stock Split, the Company may use up to
$350,000 of the proceeds of the Notes to pay in cash the first amortization payment due under the
Senior Indebtedness after the Reverse Stock Split. Notwithstanding the foregoing, the Company
shall be permitted to use the proceeds from the sale of the Notes for payments made pursuant to the
Settlement Agreement and Release dated May 9, 2006, between CombineNet, Inc. and the Company and
for the payment described on Schedule 4(d) to the Note Purchase Agreement.

(o) Conduct of Business. The business of the Company and its Subsidiaries shall not
be conducted in violation of any law, ordinance or regulation of any governmental entity, except
where such violations would not result, either individually or in the aggregate, in a Material
Adverse Effect.

(p) Integration. None of the Company, its Subsidiaries, their affiliates and any
Person acting on their behalf will take any action or steps referred to in Section 3(h) that would
require registration of any of the Notes under the 1933 Act or cause the offering of the Notes to
be integrated with other offerings.

(q) Listing. So long as any Notes are outstanding, the Company shall use commercially
reasonable efforts to continue the listing and trading of its Common Stock on the Nasdaq Capital
Market or other stock exchange or automated quotation system on which the Common Stock is then
traded and shall comply in all respects with the reporting, filing and other obligations under the
bylaws or rules of the National Association of Securities Dealers, Inc. (the “NASD”), such
exchanges, or such electronic system, as applicable.

(r) Transactions with Affiliates. Until such time as the Notes shall have been repaid
in full, the Company shall not without the prior written consent of the Holders, enter into any
transaction, including without limitation, the purchase, sale or exchange of property or the
rendering of any service, with any affiliate, except in the ordinary course of and pursuant to the
reasonable requirements of the Company’s business and upon fair and reasonable terms no less
favorable to the Company than the Company would obtain in a comparable arm’s-length transaction
with a person who is not an affiliate of the Company.

(s) Insurance. Until such time as the Notes shall have been repaid in full, the
Company shall maintain in full force and effect the insurance policies that are in effect as of the
date of this Agreement or appropriate replacement policies. The Company shall not allow any lapse
in coverage under such policies without providing Buyers thirty (30) days prior written notice.

(t) Consent to Grant Subordinated Liens and Security Interests. The Company shall use
commercially reasonable efforts to obtain the consent of the required holders of the Senior
Indebtedness to permit the Company to grant subordinated Liens and security interests to the
Holders in all assets of the Company and its Subsidiaries.

5. REGISTER; TRANSFER OF NOTES.

(a) Register. The Company shall maintain at its principal executive offices (or such
other office or agency as it may designate by notice to each holder of Notes), a register for the
Notes, in which the Company shall record the name and address of the Person in whose name the Notes
have been issued (including the name and address of each transferee) and the principal amount of
Notes held by such Person. The Company shall keep the register open and available at all times
during business hours for inspection of any Holder or its legal representatives.

(b) Transfer of Notes. If a Buyer effects a sale, assignment or transfer of the Notes
in accordance with Section 2(f) hereof, the Company shall permit the transfer and shall promptly
issue one or more Notes to the applicable Buyer in such name and in such denominations as specified
by such Buyer to effect such sale, transfer or assignment. The Company acknowledges that a breach
by it of its obligations hereunder will cause irreparable harm to a Buyer. Accordingly, the
Company acknowledges that the remedy at law for a breach of its obligations under this Section 5(b)
will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the
provisions of this Section 5(b), that a Buyer shall be entitled, in addition to all other available
remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and
transfer, without the necessity of showing economic loss and without any bond or other security
being required.

6. CONDITIONS TO THE COMPANY’S OBLIGATION TO SELL.

The obligation of the Company hereunder to issue and sell the Notes to each Buyer at the

that speak as of a specific date), and such Buyer shall have performed, satisfied and complied in
all material respects with the covenants, agreements and conditions required by this Agreement to
be performed, satisfied or complied with by such Buyer at or prior to the Closing Date.

consent to the exclusive jurisdiction of the United States federal courts and the state courts
located in the County of Philadelphia, Commonwealth of Pennsylvania, in any suit or proceeding

respect of such suit or proceeding may be determined in such courts. The Company and the Buyers
irrevocably waive the defense of an inconvenient forum to the maintenance of such suit or
proceeding in such forum. The Company and the Buyers further agree that service of process upon
such party mailed by first class mail shall be deemed in every respect effective service of process
upon such party in any such suit or proceeding. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT
MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR
IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

(b) Counterparts. This Agreement may be executed in two or more identical
counterparts, all of which shall be considered one and the same agreement and shall become
effective when counterparts have been signed by each party and delivered to the other party;
provided that a facsimile signature shall be considered due execution and shall be binding upon the
signatory thereto with the same force and effect as if the signature were an original, not a
facsimile signature.

(c) Headings. The headings of this Agreement are for convenience of reference and
shall not form part of, or affect the interpretation of, this Agreement.

(d) Severability. If any provision of this Agreement shall be invalid or

written agreements between the Buyers, the Company, their affiliates and Persons acting on their

provisions of this Section 8(e) shall be binding on all Buyers and holders of Notes, as applicable.
No provision hereof may be waived other than by an instrument in writing signed by the party
against whom enforcement is sought. No such amendment shall be effective to the extent that it
applies to less than all of the holders of the applicable Notes then outstanding. No consideration
shall be offered or paid to any Person to amend or consent to a waiver or modification of any
provision of any of the Transaction Documents unless the same consideration also is offered to all

other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and
hold harmless each Buyer and each other holder of the Notes and all of their stockholders,
partners, members, officers, directors, employees and direct or indirect investors and any of the
foregoing Persons’ agents or other representatives (including, without limitation, those retained
in connection with the transactions contemplated by this Agreement) (collectively, the
"Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses,
costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective
of whether any such Indemnitee is a party to the action for which indemnification hereunder is
sought), and including reasonable attorneys’ fees and disbursements (the “Indemnified
Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any
representation or warranty made by the Company in the Transaction Documents having been incorrect
in any material respect when made, (b) any breach of any covenant, agreement or obligation of the
Company contained in any Transaction Documents or (c) any cause of action, suit or claim brought or
made against such Indemnitee by a third party (including for these purposes a derivative action
brought on behalf of the Company) and arising out of or resulting from (i) the execution, delivery,
performance or enforcement of any Transaction Documents, (ii) any transaction financed or to be
financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the
Notes, or (iii) the status of such Buyer or holder of the Notes as an investor in the Company
pursuant to the transactions contemplated by the Transaction Documents. To the extent that the
foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make
the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities
which is permissible under applicable law.

(l) No Strict Construction. The language used in this Agreement will be deemed to be
the language chosen by the parties to express their mutual intent, and no rules of strict
construction will be applied against any party.

(m) Remedies. Each Buyer and each holder of the Notes shall have all rights and
remedies set forth in the Transaction Documents and all rights and remedies which such holders have
been granted at any time under any other agreement or contract and all of the rights which such
holders have under any law. Any Person having any rights under any provision of this Agreement
shall be entitled to enforce such rights specifically (without posting a bond or other security),
to recover damages by reason of any breach of any provision of this Agreement and to exercise all
other rights granted by law. Furthermore, the Company recognizes that in the event that it fails
to perform, observe, or discharge any or all of its obligations under the Transaction Documents,
any remedy at law may prove to be inadequate relief to the Buyers. The Company therefore agrees
that the Buyers shall be entitled to seek temporary and permanent injunctive relief in any such
case without the necessity of proving actual damages and without posting a bond or other security.

(n) Payment Set Aside. To the extent that the Company makes a payment or payments to
the Buyers hereunder or pursuant to any of the other Transaction Documents or the Buyers enforce or
exercise their rights hereunder or thereunder, and such payment or payments or the proceeds of such
enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent
or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or
otherwise restored to the Company, a trustee, receiver or any other Person under any law
(including, without limitation, any bankruptcy law, foreign, state or federal law, common law or
equitable cause of action), then to the extent of any such restoration the obligation or part
thereof originally intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such enforcement or setoff had not occurred.

Whereas, the Company has entered into that certain Agreement and Plan of Merger (the
“Unify Merger Agreement”) by and between UCA Merger Sub, Inc. (“UCA”), a

subsidiary of the Company (the “Unify Acquisition”); and

Whereas, certain financings are contemplated in order to consummate the Infonow and Unify

Whereas, in order to facilitate the completion of the Infonow and Unify Acquisitions and
the related transactions (collectively, the “Transactions”), all of the outstanding Series
C Preferred Stock in the Company, par value $.00001, (the “Series C Stock”) is to be converted into
shares of the Company’s Common Stock, par value $.00001 per share (the “Common Stock”), and certain
outstanding warrants to acquire Common Stock issued to the holders of the Series C Stock are to be
exercised for shares of Common Stock;

Now, therefore, in consideration of the foregoing and other good and valuable
consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned hereby
consents and agrees as follows:

1. Conversion of Series C Stock. To the extent that the undersigned is a holder of
any shares of Series C Stock, the undersigned hereby represents, warrants, consents and agrees as
follows:

(a) The undersigned is the holder of shares of Series C Stock (the “C Shares”). The
undersigned, pursuant to the provisions set forth in Section 5 of the Certificate of Designations
regarding the Series C Stock (the “Certificate”), hereby irrevocably elects to convert, as
soon as practicable, the number of C Shares held by the undersigned into such number of fully paid
and non-assessable shares of Common Stock of the Company determined under Section 5 of the
Certificate, with the Applicable Conversion Price (as defined in the Certificate) being $1.00.

(b) In furtherance of the foregoing, the undersigned holder of C Stock consents and agrees
that the following amendment to the Certificate shall be filed, as necessary:

“Upon the first practicable date all outstanding shares of Series C Preferred Stock
shall automatically be converted into shares of Common Stock in accordance with the
provisions of Section 5, with the Applicable Conversion Price being $1.00.”

(c) Upon the conversion of the Series C Stock as contemplated above, the undersigned consents
to the termination of the Certificate.

2. Covenants Regarding Warrants. Regarding those Warrants (the “Warrants”)
issued to the undersigned pursuant to that certain Subscription Agreement, dated as of January 31,
2005 (the “Subscription Agreement”) between the undersigned and the Company, and
held by the undersigned, the undersigned the undersigned hereby consents and agrees Section
1(c)(iii) of the Warrant is amended to provided that the Fair Market Value is $2.50. Further, the
undersigned elects to exercise such Warrants under the cashless exercise provision, Section 1(c) of
the Warrant, hereby surrenders the right to purchase 50% of the Warrant Shares (as defined in the
Warrant) and hereby requests the issuance of 50% of the Warrant Shares. The certificate(s) for the
shares issuable upon such net issue election shall be issued in the name of the undersigned or as
otherwise indicated below.

3. Lost or Destroyed Original Certificates. In the event that the undersigned has not
attached the certificates representing the undersigned’s Series C Shares and Warrants, or,
alternatively, the Series C Convertible Note (the “Series C Note”) issued
under the Subscription Agreement between the undersigned and the Company (and which by its terms
automatically converted into C Shares and Warrants), then the undersigned represents (i) that such
original certificates representing the C Shares and Warrants or the Series C Note (the “Original
Certificates”), have been lost or destroyed, and (ii) that neither the Original Certificates nor
the securities represented thereby, nor any interest therein, in whole or in part, have been
assigned, pledged, or otherwise transferred, and that the undersigned remains the sole owner
thereof. Further, the undersigned agrees to deliver to the Company for cancellation said Original
Certificates should the same ever be recovered. The undersigned agrees to indemnify and hold the
Company harmless for misrepresentation and/or breach of this Section 3.

4. Common Stock Certificates. Please issue a certificate or certificates representing
said shares of Common Stock in the name of the undersigned or in such other name as is specified
below:

5. Investment Intent. The undersigned hereby represents and warrants that the
aforesaid shares of Common Stock to be received upon such conversion of C Stock and exercise of the
Warrants, are being acquired for the account of the undersigned for investment and not with a view
to, or for resale, in connection with the distribution thereof, and that the undersigned has no
present intention of distributing or reselling such shares.

6. Consent and Waiver. The actions contemplated hereby are hereby authorized,
approved and declared advisable and in the best interests of the Company and its stockholders, and
the undersigned hereby consents to all of the foregoing. The undersigned hereby waives any and all
failures or notice or other rights inconsistent with any of the foregoing.

7. Effect on Registration Statement. The undersigned acknowledges and agrees, that
pursuant to the Investors’ Agreement (the “Investors’ Agreement”) among the
Company, the undersigned and the other Investors (as defined therein), the prospectus (the
“Prospectus”) related to the Registration Statement on Form S-2 registering the Investor’s
Conversion Shares for resale (which was declared effective by the Securities and Exchange
Commission (the “SEC”) on Friday, July 22, 2005), the Company has suspended use of the
Prospectus in connection with an Allowed Delay (as defined in the Investors’ Agreement) and as
required by the applicable rules and regulations of the SEC due to previous acquisitions by the
Company. The undersigned acknowledges and agrees that the Prospectus may be suspended further upon
the completion of the Transactions, and potential future transactions, that the suspension(s) will
continue until the SEC approves requisite amendments to the Prospectus, and that no penalties will
be due as a result of such suspension(s). For the avoidance of doubt, the undersigned also
acknowledges and agrees that no prior penalties were due under the Investors Agreement or the
Series C Notes, since the Registration Statement was declared effective prior to the Effectiveness
Deadline (as defined in the Investors’ Agreement).

The consent of the undersigned to the conversion of the Series C Stock, the amendment to and
exercise of the Warrants, and the waivers, consents and agreements set forth herein, are
irrevocable.
