Liens, other than Permitted Liens.

                      (ii) None of the Intellectual Property is subject to any

        sublicenses and other agreements relating to off-the-shelf software
        which is commercially available on a retail basis and used solely on the
        computers of the Company or its Subsidiaries (collectively, the "IP
        Agreements"). The Company and each of its Subsidiaries is not, nor to
        the Knowledge of the Company is any other party thereto, in breach of or
        default thereunder in any respect, nor is there any event which with
        notice or lapse of time or both would constitute a default thereunder.

        effect, and will continue to be so on identical terms immediately
        following the Initial Closing and the Subsequent Closing, as the case

        creditors' rights generally and by general principles of equity relating
        to enforceability (regardless of whether considered in a proceeding at
        law or in equity).

                      (iv) None of the Intellectual Property currently sold or
        licensed by the Company or any of its Subsidiaries to any Person or used

licensed to such Person or used by the Company or any of its Subsidiaries. To
the Knowledge of the Company, no Person is infringing upon or otherwise
violating the Intellectual Property rights of the Company or any of its
Subsidiaries.

its Subsidiaries to use any Intellectual Property owned by any director,
officer, employee or consultant of the Company or any of its Subsidiaries (or
persons the Company or any of its Subsidiaries presently intends to hire). To
the Company's Knowledge, at no time during the conception or reduction to
practice of any of the Intellectual Property of the Company or any of its
Subsidiaries was any developer, inventor or other contributor to such
Intellectual Property operating under any grants from any Governmental Authority
or subject to any employment agreement, invention assignment, nondisclosure

Intellectual Property.

effective to perform the functions for which they were established. The
Company's auditors and the Audit Committee of the Board of Directors have been
advised of: (i) any significant deficiencies and material weaknesses



                                       24

in the design or operation of internal controls over financial reporting which
are reasonably likely to adversely affect the Company's ability to record,
process, summarize, and report financial information; and (ii) any fraud,
whether or not material, that involves management or other employees who have a
significant role in the Company's internal controls over financial reporting.
Since the date of the most recent evaluation of such disclosure controls and
procedures, there have been no changes in internal controls over financial
reporting that have materially affected, or are reasonably likely to materially
affect, the Company's internal control over financial reporting. The principal
executive officer and the principal financial officers of the Company have made
all certifications required by the Sarbanes-Oxley Act and any related rules and
regulations promulgated by the Commission thereunder, and the statements
contained in any such certification are complete and correct. The Company is in
compliance in all material respects with all provisions of the Sarbanes-Oxley
Act that are effective and applicable to the Company, except for the
requirements of the Sarbanes-Oxley Act which are not yet required to be complied
with by the Company. The Company has established procedures to implement timely
additional rules and regulations applicable to the Company that may be
promulgated by the Commission pursuant to the Sarbanes-Oxley Act.

                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF THE LENDERS

               Each of the Lenders hereby represents and warrants, severally and
not jointly, to the Company as follows:

               4.1 Existence and Power. Such Lender (a) is a limited
partnership, corporation, partnership or limited liability company duly
organized and validly existing under the laws of the jurisdiction of its
formation and (b) has the requisite partnership, corporate or limited liability
company, as the case may be, power and authority to execute, deliver and perform
its obligations under this Agreement and each of the other Transaction Documents
to which it is a party.

               4.2 Authorization; No Contravention. The execution, delivery and
performance by such Lender of this Agreement and each of the other Transaction
Documents to which it is a party and the transactions contemplated hereby and
thereby, (a) have been duly authorized by all necessary partnership, corporate
or limited liability company, as the case may be, action, (b) do not contravene
the terms of such Lender's organizational documents, or any amendment thereof,
(c) do not violate, conflict with or result in any breach or contravention of,
or the creation of any Lien under, any Contractual Obligation of such Lender or
any Requirement of Law applicable to such Lender, and (d) do not violate any
Orders of any Governmental Authority against, or binding upon, such Lender.

               4.3 Governmental Authorization; Third Party Consents. Except for
the Stockholder Approval, no approval, consent, compliance, exemption,
authorization or other action by, or notice to, or filing with, any Governmental
Authority or any other Person, and no lapse of a waiting period under any
Requirement of Law, is necessary or


                                       25

required in connection with the execution, delivery or performance by, or
enforcement against, such Lender of this Agreement and each of the other
Transaction Documents to which it is a party or the transactions contemplated
hereby and thereby.

               4.4 Binding Effect. This Agreement and each of the other
Transaction Documents to which such Lender is a party, have been duly executed
and delivered by such Lender, and this Agreement and each of the other
Transaction Documents to which such Lender is a party, constitute the legal,
valid and binding obligations of such Lender, enforceable against it in
accordance with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer,
moratorium or similar laws affecting the enforcement of creditors' rights
generally or by equitable principles relating to enforceability (regardless of
whether considered in a proceeding at law or in equity).

               4.5 Purchase for Own Account. The Notes and the Issuable Shares
or Common Shares to be acquired by such Lender, respectively, are being or will
be acquired for its own account and with no intention of distributing or
reselling such Notes, Issuable Shares or Common Shares or any part thereof in
any transaction that would be in violation of the securities laws of the United
States of America, any state of the United States or any foreign jurisdiction,
without prejudice, however, to the rights of such Lender at all times to sell or
otherwise dispose of all or any part of such Notes, Issuable Shares or Common
Shares under an effective registration statement under the Securities Act, or
under an exemption from such registration available under the Securities Act,
and subject, nevertheless, to the disposition of such Lender's property being at
all times within its control. If such Lender should in the future decide to
dispose of any of such Notes, Issuable Shares or Common Shares, such Lender
understands and agrees that it may do so only in compliance with the Securities
Act and applicable state and foreign securities laws, as then in effect. Such
Lender agrees to the imprinting for so long as required by law, of a legend on
certificates representing all of its Notes, Issuable Shares or Common Shares and
shares of Common Stock issuable upon conversion of its Issuable Shares to the
following effect:

               THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
               REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
               "ACT"), OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES
               OR ANY FOREIGN JURISDICTION. THE SECURITIES MAY NOT BE
               TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
               STATEMENT UNDER SUCH ACT AND APPLICABLE STATE AND FOREIGN
               SECURITIES LAWS OR PURSUANT TO AN APPLICABLE EXEMPTION FROM THE
               REGISTRATION REQUIREMENTS OF SUCH ACT AND SUCH LAWS.



                                       26

               4.6 Restricted Securities. Such Lender understands that the
Notes, the Issuable Shares and the Common Shares will not be registered at the
time of their issuance under the Securities Act for the reason that the sale
provided for in this Agreement is exempt pursuant to Section 4(2) of the
Securities Act and that the reliance of the Company on such exemption is
predicated in part on such Lender's representations set forth herein.

               4.7 Accredited Investor. Such Lender is an "Accredited Investor"
within the meaning of Rule 501 of Regulation D under the Securities Act, as
presently in effect.

               4.8 Experience. Such Lender, either alone or together with its
representatives, has such knowledge, sophistication and experience in business
and financial matters so as to be capable of evaluating the merits and risks of
the prospective investment in its Notes, Issuable Shares or Common Shares (the
"Securities"), and has so evaluated the merits and risks of such investment.
Such Lender is able to bear the economic risk of an investment in the Securities
and, at the present time, is able to afford a complete loss of such investment.

               4.9 Access to Information. Such Lender has reviewed the SEC
Reports and has been afforded: (a) the opportunity to ask such questions as it
has deemed necessary of, and to receive answers from, representatives of the
Company concerning the terms and conditions of the offering of the Securities
and the merits and risks of investing in the Securities; (b) access to publicly
available information about the Company and the Subsidiaries and the Condition
of the Company sufficient to enable it to evaluate its investment; and (c) the
opportunity to obtain such additional publicly available information that the
Company possesses or can acquire without unreasonable effort or expense that is
necessary to make an informed investment decision with respect to the
investment. Neither such inquiries nor any other investigation conducted by or
on behalf of such Lender or its representatives or counsel shall modify, amend
or affect such Lender's right to rely on the truth, accuracy and completeness of
the SEC Reports and the Company's representations and warranties contained in
the Transaction Documents.

               4.10 General Solicitation. Such Lender is not purchasing the
Securities as a result of any advertisement, article, notice or other
communication regarding the Securities published in any newspaper, magazine or
similar media or broadcast over television or radio or presented at any seminar
or any other general solicitation or general advertisement.

               4.11 Reliance. Such Lender understands and acknowledges that: (a)
the Securities are being offered and sold to it without registration under the
Securities Act in a private placement that is exempt from the registration
provisions of the Securities Act and (b) the availability of such exemption
depends in part on, and the Company will rely upon the accuracy and truthfulness
of, the foregoing representations and such Lender hereby consents to such
reliance.



                                       27

               4.12 Qualified Institutional Buyer. Such Lender is a "qualified
institutional buyer" as defined in Rule 144A(a)(1) of the Securities Act, as
presently in effect.

               4.13 Affiliate Status. Such Lender is not an Affiliate of any
director, officer or substantial shareholder of the Company for purposes of Rule
4350(i)(1)(A) of the NASD, Inc. Marketplace Rules. In addition, except as
disclosed on Schedule 4.14, each Lender represents that it is not an Affiliate
of the other Lenders or the January 2004 Investors and that Lenders have not
entered into an agreement, arrangement or understanding with each other or any
other holder of the Company's securities for the purpose of holding, acquiring,
voting or disposing of any securities of the Company. Except as disclosed on
Schedule 4.14, the obligations of each Lender under any Transaction Document are
several and not joint with the obligations of any other Lender, and no Lender
shall be responsible in any way for the performance of the obligations of any
other Lender under any Transaction Document. Except as disclosed on Schedule
4.14, the decision of each Lender to purchase Securities pursuant to this
Agreement has been made by such Lender independently of any other Lender and
independently of any information, materials, statements or opinions as to the
business, affairs, operations, assets, properties, liabilities, results of
operations, condition (financial or otherwise) or prospects of the Company or of
any Subsidiary which may have been made or given by any other Lender or by any
agent or employee of any other Lender, and no Lender or any of its agents or
employees shall have any liability to any other Lender (or any other person)
relating to or arising from any such information, materials, statements or
opinions. Except as disclosed on Schedule 4.14, nothing contained herein or in
any Transaction Document, and no action taken by any Lender pursuant thereto,
shall be deemed to constitute the Lenders as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the
Lenders are in any way acting in concert or as a group with respect to such
obligations or the transactions contemplated by the Transaction Document. Except
as disclosed on Schedule 4.14, each Lender acknowledges that no other Lender has
acted as agent for such Lender in connection with making its investment
hereunder and that no other Lender will be acting as agent of such Lender in
connection with monitoring its investment hereunder. Except as disclosed on
Schedule 4.14, each Lender shall be entitled to independently protect and
enforce its rights, including without limitation the rights arising out of this
Agreement or out of the other Transaction Documents, and it shall not be
necessary for any other Lender to be joined as an additional party in any
proceeding for such purpose. The Lenders acknowledge that the Company has
elected to provide all Lenders with the same terms and Transaction Documents for
the convenience of the Company and not because it was required or requested to
do so by the Lenders.

               4.14 Capital Stock Ownership. Schedule 4.14 sets forth a complete
list of the capital stock, Common Stock Equivalents or other securities of the
Company (and any options, warrants, conversion privileges, subscription purchase
rights or other rights presently outstanding to purchase or otherwise acquire
any of the foregoing) beneficially owned (as defined in Rule 13d-3 under the
Exchange Act) by each Lender and its respective Affiliates as of the date
hereof.

                                   ARTICLE VII

                                 INDEMNIFICATION

               7.1 Indemnification. Except as otherwise provided in this Article
VII, the Company (the "Indemnifying Party") agrees to indemnify, defend and hold
harmless each of the Lenders and their Affiliates and their respective officers,
directors, agents, employees, subsidiaries, partners, members and controlling
persons (each, an "Indemnified Party") to the fullest extent permitted by law
from and against any and all losses, Claims, or written threats thereof
(including, without limitation, any Claim by a third party), damages, expenses
(including reasonable fees, disbursements and other charges of counsel incurred
by the Indemnified Party in any action between the Indemnifying Party and the
Indemnified Party or between the Indemnified Party and any third party or
otherwise) or other liabilities (collectively, "Losses") resulting from or
arising out of any breach of any representation or warranty, covenant or
agreement by the Company in this Agreement, the Amended and Restated
Registration Rights Agreement, the Notes or the Security Agreement. The amount
of any payment to any Indemnified Party herewith in respect of any Loss shall be
of sufficient amount to make such Indemnified Party whole for any diminution in
value of the Issuable Shares or Common Shares, as applicable, directly caused by
such breach. In connection with the obligation of the Indemnifying Party to
indemnify for expenses as set forth above, the Indemnifying Party shall, upon
presentation of appropriate invoices containing reasonable detail, reimburse
each Indemnified Party for all such expenses (including reasonable fees,
disbursements and other charges of counsel incurred by the Indemnified Party in
any action between the Indemnifying Party and the Indemnified Party or between
the Indemnified Party and any third party) as they are incurred by such
Indemnified Party; provided, however, that if an Indemnified Party is reimbursed
under this Article VII for any expenses, such reimbursement of expenses shall be
refunded to the extent it is finally judicially determined that the Losses in
question resulted primarily from the willful misconduct or gross negligence of
such Indemnified Party.

               7.2 Notification. Each Indemnified Party under this Article VII
shall, promptly after the receipt of notice of the commencement of any Claim
against such Indemnified Party in respect of which indemnity may be sought from
the Indemnifying Party under this Article VII, notify the Indemnifying Party in
writing of the commencement thereof. The omission of any Indemnified Party to so
notify the Indemnifying Party of any such action shall not relieve the
Indemnifying Party from any liability which it may have to such Indemnified
Party (a) other than pursuant to this Article VII or (b) under this Article VII
unless, and only to the extent that, such omission results in the Indemnifying
Party's forfeiture of substantive rights or defenses. In case any such Claim
shall be brought against any Indemnified Party, and it shall notify the
Indemnifying Party of the commencement thereof, the Indemnifying Party shall be
entitled to assume the defense thereof at its own expense, with counsel
satisfactory to such Indemnified Party in its reasonable judgment; provided,
however, that any Indemnified Party may, at its own expense, retain separate
counsel to participate in such defense at its own expense. Notwithstanding the
foregoing, in any Claim in which both the Indemnifying Party, on the one hand,
and an Indemnified Party, on the other hand,



                                       31

are, or are reasonably likely to become, a party, such Indemnified Party shall
have the right to employ separate counsel and to control its own defense of such
Claim if, in the reasonable opinion of counsel to such Indemnified Party, either
(x) one or more defenses are available to the Indemnified Party that are not
available to the Indemnifying Party or (y) a conflict or potential conflict
exists between the Indemnifying Party, on the one hand, and such Indemnified
Party, on the other hand, that would make such separate representation
advisable; provided, however, that the Indemnifying Party (i) shall not be
liable for the fees and expenses of more than one counsel to all Indemnified
Parties and (ii) shall reimburse the Indemnified Parties for all of such fees
and expenses of such counsel incurred in any action between the Indemnifying
Party and the Indemnified Parties or between the Indemnified Parties and any
third party, as such expenses are incurred; provided, however, that if an
Indemnified Party is reimbursed under this Article VII for any expenses, such
reimbursement of expenses shall be refunded to the extent it is finally
judicially determined that the Losses in question resulted primarily from the
willful misconduct or gross negligence of such Indemnified Party. The
Indemnifying Party agrees that it will not, without the prior written consent of
the Indemnified Party, settle, compromise or consent to the entry of any
judgment in any pending or threatened Claim relating to the matters contemplated
hereby (if any Indemnified Party is a party thereto or has been actually
threatened to be made a party thereto) unless such settlement, compromise or
consent includes an unconditional release of each Indemnified Party from all
liability arising or that may arise out of such Claim. The Indemnifying Party
shall not be liable for any settlement of any Claim effected against an
Indemnified Party without the Indemnifying Party's written consent, which
consent shall not be unreasonably withheld. The rights accorded to an
Indemnified Party hereunder shall be in addition to any rights that any
Indemnified Party may have at common law, by separate agreement or otherwise;
provided, however, that notwithstanding the foregoing or anything to the
contrary contained in this Agreement, nothing in this Article VII shall restrict
or limit any rights that any Indemnified Party may have to seek equitable
relief.

               7.3 Contribution. If the indemnification provided for in this
Article VII from the Indemnifying Party is unavailable to an Indemnified Party
hereunder in respect of any Losses referred to herein, then the Indemnifying
Party, in lieu of indemnifying such Indemnified Party, shall contribute to the
amount paid or payable by such Indemnified Party as a result of such Losses in
such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party and Indemnified Party in connection with the actions which
resulted in such Losses, as well as any other relevant equitable considerations.
The relative faults of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action. The amount paid or payable by a party as a
result of the Losses referred to above shall be deemed to include, subject to
the limitations set forth in Section 7.1 and Section 7.2, any reasonable legal
or other fees, charges or expenses reasonably incurred by such party in
connection with any investigation or proceeding.



                                       32

                                  ARTICLE VIII

                                    COVENANTS

               The Company hereby covenants and agrees with the Lenders as
follows:

               8.1 Financial Statements and Other Information. If any time the
Company is not subject to the periodic disclosure obligations of the Exchange
Act, the Company shall deliver to each Lender, in form and substance
satisfactory to such Lender:

               (a) as soon as available, but not later than ninety (90) days
after the end of each fiscal year of the Company, a copy of the audited
consolidated balance sheet of the Company and its Subsidiaries as of the end of
such fiscal year and the related statements of operations and cash flows for
such fiscal year, setting forth in each case in comparative form the figures for
the previous year, all in reasonable detail and accompanied by a management
summary and analysis of the operations of the Company for such fiscal year and
by the opinion of a nationally recognized independent certified public
accounting firm which report shall state without qualification that such
financial statements present fairly the financial condition as of such date and
results of operations and cash flows for the periods indicated in conformity
with GAAP applied on a consistent basis;

               (b) as soon as available, but in any event not later than
forty-five (45) days after the end of each of the first three fiscal quarters of
each fiscal year, the unaudited consolidated balance sheet of the Company and
its Subsidiaries, and the related statements of operations and cash flows for
such quarter and for the period commencing on the first day of the fiscal year
and ending on the last day of such quarter, all certified by an appropriate
officer of the Company as presenting fairly the consolidated financial condition
as of such date and results of operations and cash flows for the periods
indicated in conformity with GAAP applied on a consistent basis, subject to
normal year-end adjustments and the absence of footnotes required by GAAP; and

               (c) as soon as available, but in any event not later than ten
(10) days after the end of each month of each fiscal year, the unaudited
consolidated balance sheet of the Company and its Subsidiaries, and the related
statements of operations and cash flows for such month and for the period
commencing on the first day of the fiscal year and ending on the last day of
such month, all certified by an appropriate officer of the Company as presenting
fairly the consolidated financial condition as of such date and results of
operations and cash flows for the periods indicated in conformity with GAAP
applied on a consistent basis, subject to normal year-end adjustments and the
absence of footnotes required by GAAP.

               8.2 FIRPTA Certificate. If requested by any of the Lenders, as
promptly as practicable, but not later than five (5) days after the end of each
fiscal year of the Company, the Company shall deliver to such Lender, in form
and substance satisfactory to such Lender, a certificate signed by the Chief
Executive Officer of the



                                       33

Company in customary form certifying that the Company is not a "foreign person"
within the meaning of Section 1445 of the Code.

               8.3 Reservation of Common Stock. The Company shall at all times
reserve and keep available out of its authorized shares of Common Stock, solely
for the purpose of issue or delivery upon conversion of the Issuable Shares, as
provided in the Series E Certificate of Determination, or upon conversion of the
Notes, as provided for in the Notes, the maximum number of shares of Common
Stock that may be issuable or deliverable upon such conversion or exercise. Such
shares of Common Stock are duly authorized and, when issued or delivered in
accordance with the Series E Certificate of Determination, or in accordance with
the Notes, as the case may be, shall be validly issued, fully paid and
non-assessable. The Company shall issue such shares of Common Stock, in
accordance with the terms of the Series E Certificate of Determination or the
terms of the Notes, as the case may be, and otherwise comply with the terms
hereof and thereof.

               8.4 Stockholder Approval. The Company will use all reasonable
commercial efforts to cause the proxy statement filed with the Commission on
December 24, 2003 to be distributed to the Company's stockholders in connection
with the solicitation of votes in favor of the matters set forth in Section 3.24
that require Stockholder Approval, including any amendments or supplements
thereto (the "Proxy Statement") to be cleared by the Commission as promptly as
practicable. The Company agrees to provide the Lenders and their respective
counsel with any written comments the Company or its counsel may receive from
the Commission with respect to the Proxy Statement promptly after the receipt of
such comments. The Company will use all reasonable commercial efforts to cause
the Proxy Statement (a) not to contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they are made, not misleading and (b) to comply as to form in all material
respects with the applicable provisions of the Exchange Act and the rules and
regulations thereunder. Following clearance by the Commission of the Proxy
Statement, the Company shall promptly distribute the Proxy Statement to its
stockholders and call and arrange for a special meeting of stockholders and take
such other actions as are required or necessary in order to obtain the
Stockholder Approval as promptly as practicable. The Company will use all
reasonable commercial efforts to hold the special meeting and obtain a vote of
the stockholders on or prior to August 15, 2004. The Board of Directors shall
recommend that the Company's stockholders vote in favor of the Stockholder
Approval.

               8.5 Financial Covenants. The Company hereby covenants and agrees
that on and after the Initial Closing and until all of the obligations under the
Notes, including, without limitation, the repayment or conversion of the
principal amount and all accrued interest outstanding thereunder, have been
satisfied in full, the Company shall at all times comply with the financial and
other covenants set forth on Schedule 8.5.

               8.6 Purchases and Sales. In the event any Lender has become aware
of or becomes aware of any material non-public information about the Company
(which the



                                       34

parties hereby agree will include (but not be limited to) any information
labeled by the Company to be material non-public information) ("Material
Non-Public Information"), such Lender shall not purchase or sell any shares of
the Company's capital stock (or securities exercisable or convertible for shares
of the Company's capital stock) until the earlier of (a) such time as the
information is no longer material as a matter of law (which the parties agree
shall be a period of at least three months after becoming aware of such material
non-public information), and (b) the time at which such information has been
disseminated publicly by the Company, and in any event not in violation of the
federal securities laws. Except as set forth in this Agreement, the Company
covenants and agrees that neither it nor any other Person acting on its behalf
will provide any Lender or its agents or counsel with any information that the
Company believes constitutes Material Non-Public Information, unless prior
thereto such Lender shall have executed a written agreement regarding the
confidentiality and use of such information. The Company understands and
confirms that each Lender shall be relying on the foregoing representations in
effecting transactions in securities of the Company.

               8.7 Proxy Matters. Notwithstanding anything herein to the
contrary, but subject to the provisions of Section 9.1 of this Agreement, if the
Registration Statement (as defined in the November Convertible Note Agreement)
has not been declared effective by the Commission on or prior to May 15, 2004,
subject to approval by the Board of Directors, the Company will promptly take
all such actions as may be necessary to withdraw the Registration Statement, and
the Company shall continue to have an obligation under Section 8.4 of this
Agreement to seek Stockholder Approval. If the Company withdraws the
Registration Statement pursuant to this Section 8.7 and receives Stockholder
Approval, the Company may, subject to approval by the Board of Directors, file a
subsequent registration statement with the Commission and provide the Company's
shareholders the opportunity to participate in a subsequent rights offering.

                                   ARTICLE IX

                                   TERMINATION

               9.1 Termination. The Lenders' obligation to consummate the
Conversion under this Agreement including, but not limited to, Sections 2.4(e),
2.4(f) and 2.4(g) and Article VI of this Agreement, shall terminate in the event
that the Company is unable to obtain Stockholder Approval pursuant to Section
8.4 on the first attempt, but in any event on August 15, 2004, if Stockholder
Approval is not obtained by such date. None of the Company or the Lenders shall
have any liability arising out of such termination.

                                    ARTICLE X

                                  MISCELLANEOUS

               10.1 Survival of Representations and Warranties. All of the
representations and warranties made herein shall survive the execution and
delivery of this Agreement until the date that is ninety (90) days after the
receipt by the Lenders of


                                       35

audited financial statements of the Company for the fiscal year ending December
31, 2004 (or, if such fiscal year changes and no such audited consolidated
financial statements are available, then the successor fiscal year), except for
(a) Sections 3.1, 3.2, 3.4, 3.7, 3.13 and 3.23, which representations and
warranties shall survive until the third anniversary of the Initial Closing
Date, and (b) Section 3.11, which shall survive until the later to occur of (i)
the lapse of the statute of limitations with respect to the assessment of any
Tax to which such representation and warranty relates (including any extensions
or waivers thereof) and (ii) sixty (60) days after the final administrative or
judicial determination of the Taxes to which such representation and warranty
relates, and no claim with respect to Section 3.11 may be asserted thereafter
with the exception of claims arising out of any fact, circumstance, action or
proceeding to which the party asserting such claim shall have given notice to
the other parties to this Agreement prior to the termination of such period of
reasonable belief that a tax liability will subsequently arise therefrom.

in exercising any right, power or remedy hereunder shall operate as a waiver

remedy preclude any other or further exercise thereof or the exercise of any
other right, power or remedy. The remedies provided for herein are cumulative
and are not exclusive of any remedies that may be available to the Company or
the Lenders at law, in equity or otherwise.

               (b) Any amendment, supplement or modification of or to any
provision of this Agreement, any waiver of any provision of this Agreement, and
any consent to any departure by the Company or the Lenders from the terms of any

in writing and signed by the Company and the Lenders, and (ii) only in the
specific instance and for the specific purpose for which made or given. Except
where notice is specifically required by this Agreement, no notice to or demand
on the Company in any case shall entitle the Company to any other or further

               10.5 Counterparts. This Agreement may be executed in any number
of counterparts and by the parties hereto in separate counterparts, each of

               10.7 Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of California, without regard
to the principles of conflicts of law thereof.

               10.8 Severability. If any one or more of the provisions contained
herein, or the application thereof in any circumstance, is held invalid, illegal
or unenforceable in any respect for any reason, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions hereof shall not



                                       38

be in any way impaired, unless the provisions held invalid, illegal or
unenforceable shall substantially impair the benefits of the remaining
provisions hereof.

               10.9 Rules of Construction. Unless the context otherwise
requires, references to sections or subsections refer to sections or subsections

Lenders shall not exceed $20,000.

               10.12 Publicity; Confidentiality. Except as may be required by
applicable Requirements of Law, none of the parties hereto shall issue a
publicity release or public announcement or otherwise make any disclosure
concerning this Agreement, the transactions contemplated hereby, the Lenders or
the business, technology and financial affairs of the Company, without prior
approval by the other parties hereto; provided, however, that nothing in this
Agreement shall restrict any of the Lenders from disclosing information (a) that
is already publicly available, (b) that was known to such Lender on a
non-confidential basis prior to its disclosure by the Company, (c) that may be
required or appropriate in response to any summons or subpoena or in connection
with any litigation, provided that such Lender will use reasonable efforts to
notify the Company in advance of such disclosure so as to permit the Company to
seek a protective order or otherwise contest such disclosure, and such Lender
will use reasonable efforts to cooperate, at the expense of the Company, with
the Company in pursuing any such protective order, (d) to the extent that such
Lender reasonably believes it appropriate in order to comply with any
Requirement of Law, (e) to such Lender's or the Company's officers, directors,
shareholders, advisors, employees, members, partners, controlling persons,
auditors or counsel or (f) to Persons from whom releases, consents or approvals
are required, or to whom notice is required to be provided, pursuant to the
transactions contemplated by the Transaction Documents. If any announcement is
required by any Requirement of Law to be made by any party hereto, prior to
making such announcement such party will deliver a draft of such announcement to
the other parties and shall give the other parties reasonable opportunity to
comment thereon. Each of the Lenders acknowledge that if such Lender becomes
aware of Material Non-Public Information, such Lender's ability to trade in the
Company's securities and to participate, to the extent otherwise eligible, in
the Rights Offering would be restricted.



                                       39

               10.13 Further Assurances. Each of the parties shall execute such
documents and perform such further acts (including, without limitation,
obtaining any consents, exemptions, authorizations or other actions by, or
giving any notices to, or making any filings with, any Governmental Authority or
any other Person) as may be reasonably required or desirable to carry out or to
perform the provisions of this Agreement.

               10.14 Waiver. The Company hereby waives the provisions set forth
in Section 8.6 of the January Convertible Note Agreement with respect to the
purchase by certain of the January 2004 Investors of Notes (and any shares of
capital stock of the Company issuable upon their conversion) pursuant to this
Agreement.
