                  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),
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 on the assets, liabilities (contingent or
otherwise), business, affairs, operations, prospects or condition (financial or
otherwise) of the Company ("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

nonassessable. Except as set forth in Schedule 3.2 to the Disclosure Schedule,

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

Transaction Documents shall constitute a legal, valid and binding obligation of
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 the exercise
in full of the Warrants (assuming such Warrants vest in full).

1986, as amended (the "Code"), and other applicable laws, rules and regulations;
(ii) each Company Plan which is intended to be qualified within the meaning of
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
prototype form of instrument the sponsor thereof has received a favorable
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
provides retiree health or life insurance benefits (whether or not insured), and
neither the Company nor the Subsidiaries have any obligations to provide any
such retiree benefits other than as required pursuant to Section 4980B of the
Code or other applicable law.

                  (c) No Company Plan is a "multiemployer plan" as defined in
Section 4001(a)(3) of ERISA) or a plan subject to the minimum funding
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
Revenue Service or other governmental agencies are pending, threatened or in
progress.

                  3.21 Private Placement. Neither the Company nor any person
acting on the Company's behalf has sold or offered to sell or solicited any
offer to buy the Shares, the Warrants or the Warrant Shares by means of any form
of general solicitation or advertising. Neither the Company nor any of its
Affiliates nor any person acting on the Company's behalf has, directly or
indirectly, at any time within the past six (6) months, made any offer or sale
of any security or solicitation of any offer to buy any security under
circumstances that would (i) eliminate the availability of the exemption from
registration under Regulation D under the Securities Act in connection with the
sale or issuance of the Shares, the Warrants and the Warrant Shares as
contemplated hereby or (ii) cause the offering or issuance of the Shares, the


                                       10


Warrants or the Warrant Shares pursuant to this Agreement or any of the
Transaction Documents to be integrated with prior offerings by the Company for
purposes of any applicable law, regulation or stockholder approval provisions.
None of the Company or any of the Subsidiaries is, or is an Affiliate of, an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended. None of the Company or any of the Subsidiaries is a United States
real property holding corporation within the meaning of the Foreign Investment
in Real Property Tax Act of 1980. No consent, license, permit, waiver approval
or authorization of, or designation, declaration, registration or filing with,
the SEC or any state securities regulatory authority is required in connection
with the offer, sale, issuance or delivery of the Shares, the Warrants or the
Warrant Shares other than the possible filing of Form D with the SEC.

                  3.22 Material Changes. Except as set forth on Schedule 3.22 to
the Disclosure Schedule, since the date of the Balance Sheet, the Company has
conducted its business only in the ordinary course, consistent with past
practice, and since such date there has not occurred: (i) any event, occurrence
or development that has had, or that could reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect on the Company or
any of the Subsidiaries; (ii) any amendments or changes in the charter documents
or by-laws of the Company or the Subsidiaries; (iii) any: (A) incurrence,
assumption or guarantee by the Company or the Subsidiaries of any debt for
borrowed money other than (1) equipment leases made in the ordinary course of
business, consistent with past practice and (2) any such incurrence, assumption
or guarantee with respect to an amount of $25,000 or less that has been
disclosed in the SEC Documents; (B) issuance or sale of any securities
convertible into or exchangeable for securities of the Company other than to
directors, employees and consultants pursuant to existing equity compensation or
stock purchase plans of the Company; (C) issuance or sale of options or other
rights to acquire from the Company or the Subsidiaries, directly or indirectly,
securities of the Company or any securities convertible into or exchangeable for
any such securities, other than options issued to directors, employees and
consultants in the ordinary course of business, consistent with past practice;
(D) issuance or sale of any stock, bond or other corporate security other than
to directors, employees and consultants pursuant to existing equity compensation
or stock purchase plans of the Company; (E) declaration or making of any payment
or distribution to stockholders or purchase or redemption of any share of its
capital stock or other security other than to or from directors, officers and
employees of the Company or the Subsidiaries as compensation for or in
connection with services rendered to the Company or the Subsidiaries (as
applicable) or for reimbursement of expenses incurred on behalf of the Company
or the Subsidiaries (as applicable); (F) sale, assignment or transfer of any of
its intangible assets except in the ordinary course of business, consistent with
past practice, or cancellation of any debt or claim except in the ordinary

                                       11


assumption by the Company or any of the Subsidiaries of any lien on any asset or
any making of any loan, advance or capital contribution to or investment in any
Person, in an aggregate amount which exceeds $25,000 outstanding at any time;
(v) any entry into, amendment of, relinquishment, termination or non-renewal by
the Company or the Subsidiaries of any material contract, license, lease,
transaction, commitment or other right or obligation, other than in the ordinary
course of business, consistent with past practice; or (vi) any transfer or grant
of a right with respect to the Intellectual Property Rights owned or licensed by
the Company or the Subsidiaries, except as among the Company and the
Subsidiaries.

                  3.23 Regulatory Permits. The Company and the Subsidiaries
possess all certificates, approvals, authorizations and permits issued by the
appropriate federal, state, local or foreign regulatory authorities necessary to
conduct their businesses as described in the SEC Documents, except where the
failure to possess such permits does not, and could not have, individually or in
the aggregate, a Material Adverse Effect (the "Material Permits"), and the
Company has not received any written notice of proceedings relating to the
revocation or modification of any Material Permits except as described in the
SEC Documents.

                  3.24 Transactions with Affiliates and Employees. Except as set
forth in the SEC Documents or on Schedule 3.24 to the Disclosure Schedule, none
of the officers or directors of the Company and, to the knowledge of the
Company, none of the employees of the Company, is presently a party to any
transaction or agreement with the Company (other than for services as employees,
officers and directors) exceeding $60,000, 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 officer, director or such employee or, to the knowledge
of the Company, any entity in which any officer, director, or any such employee
has a substantial interest or is an officer, director, trustee or partner.

                  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


                                       12


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
SEC Filings, the Company maintains 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 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 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 (other than Tudor and its Affiliates), in their capacity as
directors of the Company. The Company understands and confirms that each
Purchaser will rely on the representations and covenants contained herein in
effecting the transactions contemplated by this Agreement and the Transaction
Documents, and in the securities of the 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.

         4. Representations and Warranties of the Purchasers. Each Purchaser
represents and warrants, severally and not jointly, to the Company as follows:

                                       13


                  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.
Each 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. Each Purchaser is
acquiring the Shares, Warrants and 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. Each 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. Each 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. Each 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. Each Purchaser understands that
the Shares, the Warrants 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. Each Purchaser understands
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 each 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.

                                       14


                  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 Securities. 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, Warrants and
Warrant Shares and the business, properties, prospects and financial condition
of the Company.

         6. Certain Covenants and Agreements.

                  6.1. Transfer of Securities. Each Purchaser 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


                                       17


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
judicial interpretation or pronouncement), or (iii) if such legend is not


                                       18


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 the holder has complied with the
applicable provisions of Rule 144). 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 (provided that there is an
effective registration statement covering the resale of the Shares or the
Warrant Shares, as the case may be), 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 (other than Tudor and its Affiliates), 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, 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,

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.

                                       19


                  6.5 Filing of Information. The Company shall use best efforts
to, and shall, promptly after the date hereof and in any event on or prior to
June 30, 2004, make current in all respects all filings and reports required by
applicable securities laws, including the preparation and filing of all periodic
reports under the Exchange Act, the filing of audited financial statements for
fiscal year 2003, and the filing of any statements required by or pursuant to
the Securities Act. The Company covenants to timely file (or obtain extensions
in respect thereof and file within the applicable grace period) all reports
(other than the periodic reports with respect to fiscal year 2003 and the first
quarter of 2004) 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. 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 as of 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) with respect to warrants
to purchase Common Stock issued to Tejas and as described in Section 2.4 hereof,
and (vi) in connection with lease lines, bank loans, corporate partnering or
other similar transactions, provided such issuances described in this clause
(vi) 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 the
proceeds from the sale of the Shares shall be used by the Company for working
capital and general corporate purposes or any other purpose approved by the
Company's board of director, including, without limitation, growth initiatives,
capital expenditures and potential acquisitions; under no circumstances shall
any portion of the proceeds be applied to: (i) the payment of dividends or other


                                       20


distributions on any capital stock or other securities of the Company; (ii) the
purchase of debt or equity securities of any Person for cash, including the
Company, except in connection with investment of excess cash in high quality
(A1/P1 or better) money market instruments having maturities of one year or
less; (iii) any expenditure not directly related to the business of the Company;
or (iv) the call, repurchase or redemption of any Company equity or
equity-equivalent securities.

                  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 as of 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, and (vii) 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.

                  (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


                                       21


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 fails to exercise its
right hereunder to purchase its full pro rata share of New Securities.

                  (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 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.

         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,
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:

                                       22


                  (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 7. 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 7.

                  (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


                                       23


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 hereunder
in excess of $23,187,505.

                  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 7,
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
identity of the person, persons, entity or entities may require.

                  8.3      Notices.

                  (a) Any notices, reports or other correspondence (hereinafter
collectively referred to as "correspondence") required or permitted to be given
hereunder shall be sent by postage prepaid first class mail, overnight courier
or telecopy, or delivered by hand to the party to whom such correspondence is
required or permitted to be given hereunder. The date of giving any notice shall
be the date of its actual receipt.
