         TRADE SECRETS AND PROPRIETARY INFORMATION. The Executive agrees and
understands that due to the Executive's position with the Company, the Executive
will be exposed to, and has received and will receive, confidential and
proprietary information of the Company or relating to the Company's business or
affairs collectively, the "Trade Secrets"), including but not limited to
technical information, product information and formulae, processes, business and
marketing plans, strategies, customer information, other information concerning
the Company's services or products, promotions, development, financing,
expansion plans, business policies and practices and other forms of information
considered by the Company to be proprietary and confidential and in the nature
of trade secrets. Trade Secrets shall not include any such information which (A)
was known to the Executive prior to his employment by the Company or (B) was or
becomes generally available to the public other than as a result of a disclosure
by the Executive in violation of the provisions of this Section. Except to the
extent that the proper performance of the Executive's duties, services and
responsibilities hereunder may require disclosure, the Executive agrees that
during the Employment Term and at all times thereafter the Executive will keep
such Trade Secrets confidential and will not disclose such information, either
directly or indirectly, to any third person or entity without the prior written
consent of the Company. This confidentiality covenant has no temporal,
geographical or territorial restriction. On the Termination Date unless the
Executive remains as an employee of the Company thereafter (in which case, on
the date which the Executive is no longer an employee of the Company), the
Executive will promptly supply to the Company all property, keys, notes,
memoranda, writings, lists, files, reports, customer lists, correspondence,
tapes, disks, cards, surveys, maps, logs, machines, technical data, formulae or
any other tangible product or document which has been produced by, received by
or otherwise submitted to and retained by the Executive in the course of his
employment with the Company. Any material breach of the terms of this Paragraph
shall be considered Cause.

                                       3
<PAGE>

         PROHIBITED AND COMPETITIVE ACTIVITIES. The Executive and the Company
recognize that due to the nature of the Executive's engagement hereunder and the
relationship of the Executive to the Company, the Executive has had and will
have access to, has had and will acquire, and has assisted and may continue to
assist in, developing confidential and proprietary information relating to the
business and operations of the Company and its affiliates, including, without
limitation, Trade Secrets. The Executive acknowledges that such information has
been and will be of central importance to the business of the Company and its
affiliates and that disclosure of it to, or its use by, others (including,
without limitation, the Executive (other than with respect to the Company's
business and affairs)) could cause substantial loss to the Company.

         The Executive and the Company also recognize that an important part of
the Executive's duties will be to develop good will for the Company and its
affiliates through the Executive's personal contact with Clients (as defined
below), employees, and others having business relationships with the Company,
and that there is a danger that this good will, a proprietary asset of the
Company, may follow the Executive if and when the Executive's relationship with
the Company is terminated. The Executive accordingly agrees as follows:

         (i) Prohibited Activities. The Executive agrees that the Executive will
not at any time during the Employment Term: (A) (other than in the course of the
Executive's employment) disclose or furnish to any other person or, directly or
indirectly, use for the Executive's own account or the account of any other
person, any Trade Secrets, no matter from where or in what manner he may have
acquired such Trade Secrets, and the Executive shall retain all such Trade
Secrets in trust for the benefit of the Company, its affiliates and the
successors and assigns of any of them, (B) directly or through one or more
intermediaries, solicit for employment or recommend to any subsequent employer
of the Executive the solicitation for employment of, any person who, at the time
of such solicitation, is employed by the Company or any affiliate, (C) directly
or indirectly, whether for the Executive's own account or for the account of any
other person, solicit, divert, or endeavor to entice away from the Company or
any entity controlled by the Company, or otherwise engage in any activity
intended to terminate, disrupt, or interfere with, the Company's or any of its
affiliates' relationships with, Clients, or otherwise adversely affect the
Company's or any of its affiliates' relationships with Clients or other business
relationships of the Company or any affiliate thereof, or (D) publish or make
any statement critical of the Company or any shareholder or affiliate of the
Company or in any way adversely affect or otherwise malign the business or
reputation of any of the foregoing persons (any activity described in clause
(A), (B), (C) or (D) of this Section being referred to as a Prohibited
Activity"); provided, however, that if in the written opinion of Counsel, the
Executive is legally compelled to disclose Trade Secrets to any tribunal or else
stand liable for contempt or suffer other similar censure or penalty, then the
disclosure to such tribunal of only those Trade Secrets which such counsel
advises in writing are legally required to be disclosed shall not constitute a
Prohibited Activity provided that the Executive shall give the Company as much
advance notice of such disclosure as is reasonably practicable. As used herein,
the term "Clients" shall mean those persons who, at any time during the
Executive's course of employment with the Company (including, without
limitation, prior to the date of this Agreement) are or were clients or
customers of the Company or any affiliate thereof or any predecessor of any of
the foregoing.

                                       4
<PAGE>

         (ii) Non-Competition. By and in consideration of the Company's entering
into this Agreement, the Executive agrees that the Executive will not, during
the Employment Term and for a period of eighteen months thereafter, engage in
any Competitive Activity. The term "Competitive Activity" means engaging in any
of the following activities: (A) serving as a director of any Competitor (as
defined below), (B) directly or indirectly through one or more intermediaries,
either (X) controlling any Competitor or (Y) owning any equity or debt interests
in any Competitor (other than equity or debt interests which are publicly traded
and, at the time of any acquisition thereof by the Executive, do not in the
aggregate exceed 5% of the particular class of interests of such Competitor then
outstanding) (it being understood that, if interests in any Competitor are owned
by an investment vehicle or other entity in which the Executive owns an equity
interest, a portion of the interests in such Competitor owned by such entity
shall be attributed to the Executive, such portion determined by applying the
percentage of the equity interest in such entity owned by the Executive to the
interests in such Competitor owned by such entity), (C) employment by (including
serving as an officer, director or partner of), providing consulting services to
(including, without limitation, as an independent contractor), or managing or
operating the business or affairs of, any Competitor or (D) participating in the
ownership, management, operation or control of or being connected in any manner
with any Competitor. The term "Competitor" as used herein (i) during the
Employment Term, means any person (other than the Company or any of their
respective affiliates) that competes, either directly or indirectly with any of
the business conducted by the Company or any affiliate.

         REMEDIES. The Executive agrees that any breach of the terms of this
Section would result in irreparable injury and damage to the Company for which
the Company would have no adequate remedy at law. The Executive therefore agrees
that in the event of said breach or any threat of breach, the Company shall be
entitled to an immediate injunction and restraining order to prevent such breach
and/or threatened breach and/or continued breach by the Executive and/or any and
all persons and/or entities acting for and/or with the Executive, without having
to prove damages. The terms of this Paragraph shall not prevent the Company from
pursuing any other available remedies to which the Company may be entitled at
law or in equity for any breach or threatened breach hereof, including but not
limited to the recovery of damages from the Executive. The provisions of this
Section 6 shall survive any termination of this Agreement. The existence of any
claim or cause of action by the Executive against the Company, whether
predicated on this Agreement or otherwise, shall not constitute a defense to the
enforcement by the Company of the covenants and agreements of this Section.

         PROPRIETARY INFORMATION AND INVENTIONS. The Executive agrees that any
and all inventions, discoveries, improvements, processes, formulae, business
application software, patents, copyrights and trademarks made, developed,
discovered or acquired by him prior to and during the Employment Term, solely or
jointly with others or otherwise, which relate to the business of the Company,
and all knowledge possessed by the Executive relating thereto collectively, the
"Inventions"), shall be fully and promptly disclosed to the Board of Directors
and to such person or persons as the Board of Directors shall direct and the
Executive irrevocably assigns to the Company all of the Executive's right, title
and interest in and to all Inventions of the Company and all such Inventions
shall be the sole and absolute property of the Company and the Company shall be

                                       5
<PAGE>

the sole and absolute owner thereof. The Executive agrees that he will at all
times keep all Inventions secret from everyone except the Company and such
persons as the Board of Directors may from time to time direct. The Executive
shall, as requested by the Company at any time and from time to time, whether
prior to or after the expiration of the Employment Term, execute and deliver to
the Company any instruments deemed necessary by the Company to effect disclosure
and assignment of the Inventions to the Company or its designees and any patent
applications (United States or foreign) and renewals with respect thereto,
including any other instruments deemed necessary by the Company for the
prosecution of patent applications, the acquisition of letters patent and/or the
acquisition of patents or copyrights in any and all countries and to vest title
thereto in the Company or its nominee.

6. Representations and Warranties of the Executive. The Executive represents and
warrants to the Company that:

         (i) The Executive's employment by the Company as contemplated will not
conflict with, and will not be constrained by, any prior or current employment,

the Executive's rights or obligations under this Agreement without the prior
written consent of the Company.

or discharge by either party hereto at any time or any waiver or discharge of
any breach by the other party hereto of, or compliance with, any condition or
provision of this agreement to be performed by such other party, shall be deemed

         3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby
represents and warrants to each Purchaser, as of the date hereof and except as
set forth on the disclosure schedule furnished by the Company to each Purchaser
(the "DISCLOSURE SCHEDULE") attached hereto as Schedule 2, as follows:

                  3.1 INCORPORATION. Each of the Company and the Subsidiaries
(as defined in Section 3.18 below) is a corporation or other entity duly
organized, validly existing and in good standing under the laws of the State of
Delaware (or such other applicable jurisdiction of incorporation or formation as
is indicated on Schedule 3.18), and is in good standing as a foreign corporation
or other entity in each jurisdiction in which the nature of the business
conducted or the character of the property owned by it makes such qualification
necessary, except where the failure to be so qualified or in good standing, as
the case may be, would not result in a Material Adverse Effect. Each of the
Company and the Subsidiaries has all requisite corporate power and authority to
carry on its business as now conducted and to carry out the transactions
contemplated hereby. Neither the Company nor any of the Subsidiaries is in
violation of any of the provisions of its Certificate of Incorporation (or other
charter document) or By-laws.

                  3.2 CAPITALIZATION. The authorized capital stock of the
Company consists of (i) 100,000,000 shares of Common Stock, of which 34,562,901
shares were outstanding as of the date hereof, and (ii) 5,000,000 shares of
preferred stock, of which no shares are outstanding as of the date hereof. All
shares of the Company's issued and outstanding capital stock have been duly
authorized, are validly issued and outstanding, and are fully paid and
nonassessable. Except as set forth in Schedule 3.2 to the Disclosure Schedule,
there are no existing options, warrants, calls, preemptive (or similar) rights,
subscriptions or other rights, agreements, arrangements or commitments of any
character obligating the Company to issue, transfer or sell, or cause to be
issued, transferred or sold, any shares of the capital stock of the Company or
other equity interests in the Company or any securities convertible into or
exchangeable for such shares of capital stock or other equity interests,
including the Shares, the Warrants and the Warrant Shares, and there are no
outstanding contractual obligations of the Company to repurchase, redeem or
otherwise acquire any shares of its capital stock or other equity interests. The
issue and sale of the Shares, the Warrants and the Warrant Shares will not
obligate the Company to issue or sell, pursuant to any pre-emptive right or
otherwise, shares of Common Stock or other securities to any Person (other than
the Purchasers) and will not result in a right of any holder of Company
securities to adjust the exercise, conversion, exchange or reset price under
such securities.

                  3.3 REGISTRATION RIGHTS. Except as set forth on Schedule 3.3
to the Disclosure Schedule, the Company has not granted or agreed to grant to
any Person any right (including "piggy-back" and demand registration rights) to
have any capital stock or other securities of the Company registered with the
SEC or any other government authority.

                  3.4 AUTHORIZATION. All corporate action on the part of the
Company, its officers and directors necessary for the authorization, execution,
delivery and performance of this Agreement and the Transaction Documents and the
consummation of the transactions contemplated herein and therein has been taken.
When executed and delivered by the Company, each of this Agreement and the
Transaction Documents shall constitute a legal, valid and binding obligation of

                                       4
<PAGE>

the Company, enforceable against the Company in accordance with its terms,
except as such may be limited by bankruptcy, insolvency, reorganization or other
laws affecting creditors' rights generally and by general equitable principles.
The Company has all requisite corporate power and authority to enter into this
Agreement and the Transaction Documents and to carry out and perform its
obligations under their respective terms.

                  3.5 VALID ISSUANCE OF THE SHARES. The Shares, the Warrants and
the Warrant Shares have been duly authorized, and the Shares and the Warrant
Shares, upon issuance pursuant to the terms hereof and the terms of the
Warrants, respectively, will be validly issued, fully paid and nonassessable and
not subject to any encumbrances, preemptive rights or any other similar
contractual rights of the stockholders of the Company or any other Person. The
Company has reserved from its duly authorized capital stock the number of shares
of Common Stock issuable upon execution of this Agreement and upon exercise in
full of the Warrants (assuming the Warrants vest in full).

                  3.6 FINANCIAL STATEMENTS. The Company has furnished to the
Purchasers, and attached as Schedule 3.6 to the Disclosure Schedule, true and

party or by which they or any of their properties or assets are bound, except in

ordinance or restriction applicable to the Company, the Subsidiaries or any of
their properties or assets, or any judgment, writ, injunction or decree of any

Disclosure Schedule, there have been no written claims made against the Company
or any of the Subsidiaries asserting the invalidity, abuse, misuse, or

Section 401(a) of the Code is so qualified and has received a favorable
determination letter as to its qualification (or if maintained pursuant to a

opinion letter as to its qualification), and to the Company's knowledge nothing
has occurred, whether by action or failure to act, that could reasonably be
expected to cause the loss of such qualification; and (iii) no Company Plan

requirements of Section 302 or ERISA or Section 412 of the Code or Title IV of
ERISA, and neither the Company, the Subsidiaries, nor any member of their
Controlled Group has any liability or obligation in respect of, any such
multiemployer plan or plan. With respect to any Company Plan and to the
Company's knowledge, (i) no actions, suits or claims (other than routine claims
for benefits in the ordinary course) are pending or threatened, and (ii) no
administrative investigation, audit or other administrative proceeding by the
Department of Labor, the Pension Benefit Guaranty Corporation, the Internal

possess all certificates, approvals, authorizations and permits issued by the
appropriate federal, state, local or foreign regulatory authorities necessary to

                  3.25 INSURANCE. The Company and the Subsidiaries are insured
by insurers of recognized financial responsibility against such losses and risks
and in such amounts as are prudent and customary for the business in which the
Company and the Subsidiaries are engaged. The Company has no reason to believe
that it will not be able to renew existing insurance coverage for itself and the
Subsidiaries as and when such coverage expires or to obtain similar coverage
from similar insurers as may be necessary or appropriate to continue business.

                  3.26 SOLVENCY. Based on the consolidated financial condition
of the Company and the Subsidiaries as of the date hereof, (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 and 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, 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 debts
when such amounts are required to be paid. The Company has no present intention
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).

                  3.27 INTERNAL ACCOUNTING CONTROLS. Except as disclosed in the

transactions are recorded as necessary to permit preparation of financial
statements in conformity with United States generally accepted accounting
principles and to maintain asset accountability, (iii) access to assets is
permitted only in accordance with management's general or specific
authorizations, (iv) the recorded accountability for assets is compared with the
existing assets at reasonable intervals and appropriate action is taken with
respect to any differences, and (v) the Company is otherwise in compliance with
the Securities Act, the Exchange Act and all other rules and regulations
promulgated by the SEC and applicable to the Company, including such rules and
regulations to implement the Sarbanes-Oxley Act of 2002, as amended.

                  3.28 DISCLOSURE. Neither the Company nor, to the Company's
knowledge, any other Person acting on its behalf and at the direction of the
Company, has provided to any Purchaser or its agents or counsel any information
that in the Company's reasonable judgment, at the time such information was
furnished, constitutes material, non-public information, except such information
as may have been disclosed to certain Board members, who are affiliated with
certain Purchasers, in their capacity as directors of the Company. The Company
understands and confirms that each Purchaser will rely on the representations

Company after the Closing. All disclosure provided to the Purchasers 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
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. No event or circumstance has occurred or information
exists with respect to the Company or the Subsidiaries or its or their business,
properties, prospects, operations or financial conditions, which, under
applicable law, rule or regulation, requires public disclosure or announcement
by the Company but which has not been so publicly announced or disclosed. The
Company acknowledges and agrees that no Purchaser makes or has made any
representations or warranties with respect to the transactions contemplated
hereby other than those specifically set forth in Section 4.

                  3.29 DEBT OBLIGATIONS. No amounts are due and owing under that

         4. REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS. Each Purchaser
represents and warrants, severally (as to itself) and not jointly, to the
Company as follows:

                  4.1 AUTHORIZATION. All action on the part of such Purchaser
and, if applicable, its officers, directors, managers, members, shareholders
and/or partners necessary for the authorization, execution, delivery and
performance of this Agreement and the Registration Rights Agreement, and the
consummation of the transactions contemplated herein and therein, has been
taken. When executed and delivered, each of this Agreement and the Registration
Rights Agreement will constitute the legal, valid and binding obligation of such
Purchaser, enforceable against such Purchaser in accordance with its terms,
except as such may be limited by bankruptcy, insolvency, reorganization or other
laws affecting creditors' rights generally and by general equitable principles.
Such Purchaser has all requisite corporate power and authority to enter into
each of this Agreement and the Registration Rights Agreement, and to carry out
and perform its obligations under the terms of hereof and thereof.

                  4.2 PURCHASE ENTIRELY FOR OWN ACCOUNT. Such Purchaser is
acquiring the Shares, the Warrants and the Warrant Shares for its own account
for investment and not for resale or with a view to distribution thereof in
violation of the Securities Act.

                  4.3 INVESTOR STATUS; ETC. Such Purchaser certifies and
represents to the Company that it is an "accredited investor" as defined in Rule
501 of Regulation D promulgated under the Securities Act and was not organized
for the purpose of acquiring any of the Shares, the Warrants or the Warrant
Shares. Such Purchaser's financial condition is such that it is able to bear the
risk of holding the Shares for an indefinite period of time and the risk of loss
of its entire investment. Such Purchaser has sufficient knowledge and experience
in investing in companies similar to the Company so as to be able to evaluate
the risks and merits of its investment in the Company.

                  4.4 SECURITIES NOT REGISTERED. Such Purchaser understands that
the Shares, the Warrant and the Warrant Shares have not been registered under
the Securities Act, by reason of their issuance by the Company in a transaction
exempt from the registration requirements of the Securities Act, and that the
Shares, the Warrants and the Warrant Shares must continue to be held by such
Purchaser unless a subsequent disposition thereof is registered under the
Securities Act or is exempt from such registration. Such Purchaser understands

                                       13
<PAGE>

that the exemptions from registration afforded by Rule 144 (the provisions of
which are known to it) promulgated under the Securities Act depend on the
satisfaction of various conditions, and that, if applicable, Rule 144 may afford
the basis for sales only in limited amounts.

                  4.5 NO CONFLICT. The execution and delivery of this Agreement
and the Registration Rights Agreement by such Purchaser, and the consummation of
the transactions contemplated hereby and thereby, will not conflict with or
result in any violation of or default by such Purchaser (with or without notice
or lapse of time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or to a loss of a material
benefit under (i) any provision of the organizational documents of such
Purchaser or (ii) any agreement or instrument, permit, franchise, license,
judgment, order, statute, law, ordinance, rule or regulations, applicable to
such Purchaser.

                  4.6 BROKERS. Such Purchaser has not retained, utilized or been
represented by any broker or finder in connection with the transactions
contemplated by this Agreement.

                  4.7 CONSENTS. All consents, approvals, orders and
authorizations required on the part of such Purchaser in connection with the
execution, delivery or performance of this Agreement and the consummation of the
transactions contemplated herein have been obtained and are effective as of the
date hereof.

                  4.8 DISCLOSURE OF INFORMATION. Such Purchaser believes it has
received all the information it considers necessary or appropriate for deciding
whether to purchase the Shares, the Warrants and the Warrant Shares. Such
Purchaser 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 Shares, the Warrants and the Warrant Shares and the business,
properties, prospects and financial condition of the Company.

         5. CONDITIONS PRECEDENT.

                  5.1. CONDITIONS TO THE OBLIGATION OF THE PURCHASERS TO

         6. CERTAIN COVENANTS AND AGREEMENTS.

                  6.1. TRANSFER OF SECURITIES. Each Purchaser agrees severally
(as to itself only) and not jointly that it shall not sell, assign, pledge,
transfer or otherwise dispose of or encumber any of the Shares, the Warrants or
the Warrant Shares, except (i) pursuant to an effective registration statement
under the Securities Act, (ii) to an Affiliate (so long as such Affiliate agrees
to be bound by the terms and provisions of this Agreement as if, and to the
fullest extent as, such Purchaser), or (iii) pursuant to an available exemption
from registration under the Securities Act (including sales permitted pursuant
to Rule 144) and applicable state securities laws and, if requested by the
Company, upon delivery by such Purchaser of either an opinion of counsel of such
Purchaser reasonably satisfactory to the Company to the effect that the proposed
transfer is exempt from or does not require registration under the Securities
Act and applicable state securities laws or a representation letter of such
Purchaser reasonably satisfactory to the Company setting forth a factual basis
for concluding that such proposed transfer is exempt from or does not require
registration under the Securities Act and applicable state securities laws. Any
transfer or purported transfer of the Shares in violation of this Section 6.1
shall be void. The Company shall not register any transfer of the Shares in
violation of this Section 6.1. The Company may, and may instruct any transfer
agent for the Company, to place such stop transfer orders as may be required on
the transfer books of the Company in order to ensure compliance with the
provisions of this Section 6.1.

                  6.2. LEGENDS.

                           (a) To the extent applicable, each certificate or
other document evidencing the Shares and the Warrant Shares shall be endorsed
with the legend set forth below, and each Purchaser covenants that, except to
the extent such restrictions are waived by the Company, it shall not transfer
the shares represented by any such certificate without complying with the
restrictions on transfer described in this Agreement and the legends endorsed on
such certificate:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED OR
         SOLD IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID
         ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT
         SUBJECT TO, REGISTRATION UNDER SAID ACT."

                           (b) The legend set forth in Section 6.2(a) shall be
removed from the certificates evidencing the Shares and the Warrant Shares, (i)
following any sale of such Shares or Warrant Shares pursuant to Rule 144 or any
effective registration statement, or (ii) if such Shares or Warrant Shares are
eligible for sale under Rule 144(k) (and the holder of such Shares or Warrant
Shares has submitted a written request for removal of the legend indicating that
the holder has complied with the applicable provisions of Rule 144 or such

                                       17
<PAGE>

judicial interpretation or pronouncement), or (iii) if such legend is not
required under applicable requirements of the Securities Act (including judicial
interpretations and pronouncements issued by the Staff of the Commission) (and
the holder of such Shares or Warrant Shares has submitted a written request for
removal of the legend indicating that such legend is not required under
applicable requirements of the Securities Act (including such judicial
interpretations and pronouncements). The Company shall cause its counsel to
issue a legal opinion to the Company's transfer agent promptly upon the
occurrence of any of the events in clauses (i), (ii) or (iii) above to effect
the removal of the legend on certificates evidencing the Shares or the Warrant
Shares and shall also cause its counsel to issue a "blanket" legal opinion to
the Company's transfer agent promptly after the effective date of any
registration statement covering the resale of the Shares or any Warrant Shares,
if required by the Company's transfer agent, to allow sales without restriction
pursuant to an effective registration statement. The Company agrees that at such
time as such legend is no longer required under this Section 6.2(b), it will, no
later than three (3) business days following the delivery by a Purchaser to the
Company or the Company's transfer agent of a certificate representing the Shares
or Warrant Shares issued with a restrictive legend, deliver or cause to be
delivered to such Purchaser a certificate representing such Shares or Warrant
Shares that is free from all restrictive and other legends; provided that in the
case of removal of the legend for reasons set forth in clause (ii) above, the
holder of such Shares or Warrant Shares has submitted a written request for
removal of the legend indicating that the holder has complied with the
applicable provisions of Rule 144. The Company may not make any notation on its
records or give instructions to any transfer agent of the Company that enlarge
the restrictions on transfer set forth in this Section.

                  6.3 PUBLICITY. Except to the extent required by applicable
laws, rules, regulations or stock exchange requirements, neither (i) the
Company, the Subsidiaries or any of their Affiliates nor (ii) any Purchaser or
any of its Affiliates shall, without the written consent of the other, make any
public announcement or issue any press release with respect to the transactions
contemplated by this Agreement. In no event will either (i) the Company, the
Subsidiaries or any of their Affiliates or (ii) any Purchaser or any of its
Affiliates make any public announcement or issue any press release with respect
to the transactions contemplated by this Agreement without consulting with the
other party, to the extent feasible, as to the content of such public
announcement or press release.

                  6.4 MATERIAL, NONPUBLIC INFORMATION. Except as required by
law, the Company and its directors, officers, employees and agents shall not
provide any Purchaser with any material non-public information regarding the
Company or any of the Subsidiaries at any time after the Closing, except such
information as may be required to be disclosed to certain Board members, who are
affiliated with certain Purchasers, in their capacity as directors of the
Company. In the event of a breach of the foregoing covenant following the
Effective Date, or in the event that Company is legally required to make certain
disclosures to any Purchaser (and does so) following the Effective Date, then in
addition to any other remedy provided for herein, in the Transaction Documents
or in equity or at law, each Purchaser to whom information has been disclosed
(whether as a result of breach or as required by law) may request, in writing,
that the Company promptly (but in no event more than five (5) business days
after the date of such writing) publicly disclose, by press release, SEC filing,

                                       18
<PAGE>

or otherwise, an appropriate summary of the information that, in such
Purchaser's reasonable judgment, constitutes the then material non-public
information. After such five (5) business-day period, the Purchaser(s) who was
or were in receipt of such material non-public information shall be
automatically authorized to make all of the information, or any portion thereof,
available to the public generally, without incurring any liability to the
Company for such disclosure.

                  6.5 FILING OF INFORMATION. The Company covenants to timely
file (or obtain extensions in respect thereof and file within the applicable
grace period) all reports required to be filed by the Company pursuant to all
applicable securities laws, including the Exchange Act. At any time if the
Company is not required to file reports pursuant to such laws, it will prepare
and furnish to the Purchasers and make publicly available in accordance with
paragraph (c) of Rule 144 such information as is required for the Purchasers to
sell the Shares and the Warrant Shares under Rule 144. The Company further
covenants that it will take such further action as any holder of Shares or
Warrant Shares may reasonably request to satisfy the provisions of Rule 144
applicable to the issuer of securities relating to transactions for the sale of
securities pursuant to Rule 144.

                  6.6 ADDITIONAL ISSUANCE. In addition to the sale of the Shares
and the issuance of the Warrants contemplated herein, the Company may issue up
to $50,000,000 of shares of Common Stock at a purchase price per Share not less
than the Share Price to its existing stockholders (other than the Purchasers,
who waive their rights to participate in such rights offering as set forth in
Section 6.11 hereof) pursuant to a follow-on rights offering (the "RIGHTS
OFFERING"). Other than the Rights Offering, the Company shall not issue any
capital stock or other securities in connection with the raising of additional
financing or capital until all of the Shares have been registered for resale
pursuant to an effective registration statement and otherwise in accordance with
the terms set forth in the Registration Rights Agreement; provided; however,
that the foregoing shall not prohibit the Company from issuing shares of Common
Stock or securities convertible into or exercisable for Common Stock: (i) upon
conversion of the Warrants or other securities issuable upon conversion of
securities outstanding on the date hereof, (ii) to employees, consultants,
officers or directors of the Company pursuant to stock option, stock purchase or
stock bonus plans or agreements or other stock incentive plans or arrangements
approved by the Board, which are in existence as of the date hereof, (iii)
pursuant to the acquisition of another business entity or business segment of
any such entity by the Company by merger, purchase of substantially all the
assets or other reorganization or corporate partnering agreement if such
issuance is approved by the Board, (iv) in connection with any stock split,
stock dividend or recapitalization of the Company, and (v) in connection with
lease lines, bank loans, corporate partnering or other similar transactions,
provided such issuances described in this clause (v) are not primarily for the
purpose of equity financing and are approved by the Board.

                  6.7 USE OF PROCEEDS. The Company covenants and agrees that all
of the proceeds from the sale of the Shares shall be used by the Company to
effect the MSV Transaction, pay the Company's fees and expenses incurred in
connection with this offering, pay the Company's fees and expenses incurred by
the Company in connection with the MSV Transaction and pay the Broker Fee to
Tejas.

<PAGE>

                  6.8 INTEGRATION. The Company shall not sell, offer for sale or
solicit offers to buy or otherwise negotiate in respect of any security (as
defined in Section 2 of the Securities Act) that would be integrated with the
offer or sale of the Shares in a manner that would require the registration
under the Securities Act of the sale of the Shares or the issuance of the
Warrants or the Warrant Shares to the Purchasers.

                  6.9 PRE-EMPTIVE RIGHT. Each Purchaser shall have the right to
purchase a pro rata share of New Securities (as defined in this Section 6.9)
that the Company may, from time to time, propose to sell and issue. Each
Purchaser's pro rata share, for purposes of this right, is the ratio of the
number of shares of Fully Diluted Common Stock owned by such holder immediately
prior to the issuance of New Securities to the total number of shares of Fully
Diluted Common Stock outstanding immediately prior to the issuance of New
Securities. Each Purchaser shall also have the right of over-allotment to
purchase additional New Securities set forth in paragraph (b) of this Section
6.9. This pre-emptive right shall be subject to the following provisions:

                           (a) "NEW SECURITIES" shall mean any capital stock
(including Common Stock) of the Company whether now authorized or not, and any
rights, options or warrants to purchase such capital stock, and securities of
any type whatsoever that are, or may become, convertible into or exchangeable
for capital stock; provided that the term "New Securities" does not include
securities issued: (i) upon conversion of the Warrants or other securities
issuable upon conversion of securities outstanding on the date hereof, (ii) to
employees, consultants, officers or directors of the Company pursuant to stock
option, stock purchase or stock bonus plans or agreements or other stock
incentive plans or arrangements approved by the Board, which are in existence as
of the date hereof, (iii) pursuant to the acquisition of another business entity
or business segment of any such entity by the Company by merger, purchase of
substantially all the assets or other reorganization or corporate partnering
agreement if such issuance is approved by the Board, (iv) in connection with any
stock split, stock dividend or recapitalization of the Company, (v) in
connection with lease lines, bank loans, corporate partnering or other similar
transactions, provided such issuances described in this clause (v) are not
primarily for the purpose of equity financing and are approved by the Board,
(vi) to directors of the Company as compensation for their service as directors
pursuant to a restricted stock plan to be implemented and approved by the
stockholders of the Company; provided that such issuance of restricted stock
shall not exceed 100,000 shares per year; and (vii) pursuant to the Rights
Offering.

                           (b) In the event the Company proposes to undertake an
issuance of New Securities, it shall give each Purchaser certified written
notice of its intention, describing the type of New Securities, their price and
the general terms upon which the Company proposes to issue the same. Each
Purchaser shall have thirty (30) days after any such notice is mailed or
delivered to agree to purchase all or any portion of such Purchaser's pro rata
share of such New Securities for the price and upon the terms specified in the
notice by giving written notice to the Company and stating therein the quantity
of New Securities to be purchased. Each Purchaser shall have the right of
over-allotment such that if any Purchaser fails to exercise its right under this
Section 6.9 to purchase its full pro rata share of New Securities, the other
Purchasers may purchase the portion of such Purchaser's remaining portion on a
pro rata share within ten (10) days from the date such non-purchasing Purchaser

                           (c) In the event the Purchasers fail to exercise the
pre-emptive right within such thirty (30) day period and after the expiration of
the ten (10) day period for the exercise of the over-allotment provisions of
this Section 6.9, the Company shall have ninety (90) days thereafter to sell the
New Securities respecting which the Purchasers' pre-emptive right set forth in
this Section 6.9 was not exercised, at a price and upon terms no more favorable
to the purchasers thereof or to the Company than specified in the Company's
notice to the Purchasers pursuant to Section 6.9(b) above. In the event the
Company has not sold the New Securities respecting which the Purchasers'
preemptive right set forth in the Section 6.9 was not exercised within such
ninety (90) day period, the Company shall not thereafter issue or sell any New
Securities, without first again offering such securities to the Purchasers in
the manner provided in Section 6.9(b) above.

                  6.10 WAIVER OF PRE-EMPTIVE RIGHTS IN PRIOR AGREEMENTS. To the
extent any Purchaser has a pre-emptive right pursuant to Section 6.9 of the
Common Stock Purchase Agreement dated April 7, 2004 by and among the Company and
the Purchasers listed on Schedule 1 thereto and/or Section 6.9 of the Securities
Purchase Agreement dated July 1, 2004 by and among the Company and the
Purchasers listed on Schedule 1 thereto to purchase the Company's securities on
the terms set forth in such agreements, each such Purchaser hereby waives such
right with respect to the issuance of (a) the Shares, (b) the Warrants, (c) the
Warrant Shares or (d) Common Stock in the Rights Offering.

                  6.11 WAIVER OF PARTICIPATION IN RIGHTS OFFERING. Each
Purchaser hereby waives as to itself and its Affiliates the right to participate
in the Rights Offering.

                  6.12 RESERVATION OF COMMON STOCK FOR ISSUANCE; LISTING OF
SHARES. The Company agrees to reserve from its duly authorized capital stock the
total number of shares of Common Stock issuable upon execution of this Agreement
and upon the exercise in full of the Warrants. The Company agrees that at any
time, if and when its shares of Common Stock are listed on NASDAQ, that it will
use reasonable efforts to promptly list and qualify the Shares and the Warrant
Shares for trading on NASDAQ.

                  6.13 REQUIRED APPROVALS. As promptly as practicable after the
date of this Agreement, the Company shall make, or cause to be made, all filings
with any governmental or administrative agency or any other Person necessary to
consummate the transactions contemplated hereby.

         7. INDEMNIFICATION.

                  7.1 BY THE COMPANY. The Company agrees to indemnify, defend
and hold harmless each Purchaser and its Affiliates and their respective
officers, directors, agents, employees, subsidiaries, partners, members and
controlling persons (collectively, the "PURCHASER INDEMNITEES") to the fullest
extent permitted by law from and against any and all claims, losses,
liabilities, damages, deficiencies, judgments, assessments, fines, settlements,
costs or expenses (including interest, penalties and reasonable fees,

                                       21
<PAGE>

disbursements and other charges of counsel) (collectively, "LOSSES") based upon,
arising out of or otherwise in respect of any breach by the Company of any
representation, warranty, covenant or agreement of the Company contained in this
Agreement or in the Transaction Documents, or for any Losses claimed by Tejas or
any other broker or placement agent.

                  7.2 CLAIMS. All claims for indemnification by a Purchaser
Indemnitee pursuant to this Section 7 shall be made as follows:

                           (a) If a Purchaser Indemnitee has incurred or
suffered Losses for which it is entitled to indemnification under this Section
7, then such Purchaser Indemnitee shall give prompt written notice of such claim
(a "CLAIM NOTICE") to the Company. Each Claim Notice shall state the amount of
claimed Losses (the "CLAIMED AMOUNT"), if known, and the basis for such claim.

                           (b) Within 30 days after delivery of a Claim Notice,
the Company (the "INDEMNIFYING PARTY") shall provide to each Purchaser
Indemnitee (the "INDEMNIFIED PARTY"), a written response (the "RESPONSE NOTICE")
in which the Indemnifying Party shall: (i) agree that all of the Claimed Amount
is owed to the Indemnified Party, (ii) agree that part, but not all, of the
Claimed Amount (the "AGREED AMOUNT") is owed to the Indemnified Party, or (iii)
contest that any of the Claimed Amount is owed to the Indemnified Party. The
Indemnifying Party may contest the payment of all or a portion of the Claimed
Amount only based upon a good faith belief that all or such portion of the
Claimed Amount does not constitute Losses for which the Indemnified Party is
entitled to indemnification under this Section 7. If no Response Notice is
delivered by the Indemnifying Party within such 30-day period, then the
Indemnifying Party shall be deemed to have agreed that all of the Claimed Amount
is owed to the Indemnified Party.

                           (c) If the Indemnifying Party in the Response Notice
agrees (or is deemed to have agreed) that all of the Claimed Amount is owed to
the Indemnified Party, then the Indemnifying Party shall owe to the Indemnified
Party an amount equal to the Claimed Amount to be paid in the manner set forth
in this Section 8. If the Indemnifying Party in the Response Notice agrees that
part, but not all, of the Claimed Amount is owed to the Indemnified Party, then
the Indemnifying Party shall owe to the Indemnified Party an amount equal to the
agreed amount set forth in such Response Notice to be paid in the manner set
forth in this Section 8. The parties agree that the foregoing shall not be
deemed to provide that the Indemnifying Party is entitled to make a binding
determination regarding any disputed amounts owed to an Indemnified Party,
unless such Indemnified Party accepts and agrees to such determination, and both
the Indemnified Party and Indemnifying Party shall retain all rights and
remedies available to such party hereunder.

                           (d) No delay on the part of the Indemnified Party in
notifying the Indemnifying Party shall relieve the Indemnifying Party of any
liability or obligation hereunder except to the extent of any actual prejudice
caused by or arising out of such delay.

                  7.3. PAYMENT OF CLAIMS. An Indemnifying Party shall make
payment of any portion of any Claimed Amount that such Indemnifying Party has
agreed in a Response Notice that it owes to an Indemnified Party, or that such
Indemnifying Party is deemed to have agreed it owes to such Indemnifying Party,
said payment to be made within thirty (30) days after such Response Notice is
delivered by such Indemnifying Party or should have been delivered by such
Indemnifying Party, as the case may be.

                  7.4. LIMITATIONS.

                           (a) TIME FOR CLAIMS. No Indemnifying Party will be
liable for any Losses hereunder arising out of a breach of representation or
warranty unless a written claim for indemnification is given by the Indemnified
Party to the Indemnifying Party on or prior to the third anniversary of the date
on which the registration statement covering the resale of the Shares initially
became effective.

                           (b) MAXIMUM AMOUNT. Notwithstanding anything
contained herein to the contrary, no Indemnifying Party will be liable for any
Losses to any Purchaser Indemnitee hereunder in excess of the portion of the
aggregate purchase price hereunder actually paid by the related Purchaser.

                  7.5 APPLICABILITY; EXCLUSIVITY. Notwithstanding any term to
the contrary in this Section 7, the indemnification and contribution provisions
of the Registration Rights Agreement shall govern any claim made with respect to
registration statements filed pursuant thereto or sales made thereunder. The
parties hereby acknowledge and agree that in addition to remedies of the parties
hereto in respect of any and all claims relating to any breach or purported
breach of any representation, warranty, covenant or agreement that is contained
in this Agreement pursuant to the indemnification provisions of this Section 8,
all parties shall always retain the right to pursue and obtain injunctive relief
in addition to any other rights or remedies hereunder.

         8. MISCELLANEOUS PROVISIONS.

                  8.1 RIGHTS CUMULATIVE. Each and all of the various rights,
powers and remedies of the parties shall be considered to be cumulative with and
in addition to any other rights, powers and remedies which such parties may have
at law or in equity in the event of the breach of any of the terms of this
Agreement. The exercise or partial exercise of any right, power or remedy shall
neither constitute the exclusive election thereof nor the waiver of any other
right, power or remedy available to such party.

                  8.2 PRONOUNS. All pronouns or any variation thereof shall be
deemed to refer to the masculine, feminine or neuter, singular or plural, as the
