power and authority to own and use its properties and assets and to carry on its
business as currently conducted. Neither the Company nor any Subsidiary is in

incorporation, bylaws or other organizational or charter documents. Each of the
Company and the Subsidiaries is duly qualified to conduct business and is in
good standing as a foreign corporation or other entity in each jurisdiction in
which the nature of the business conducted or property owned by it makes such
qualification necessary, except where the failure to be so qualified or in good

effect on the legality, validity or enforceability of any Transaction Document,
(ii) a material adverse effect on the business or financial condition of the
Company and the Subsidiaries, taken as a whole, or (iii) a material adverse
effect on the Company's ability to perform in any material respect on a timely
basis its obligations under any Transaction Document (any of (i), (ii) or (iii),
a "Material Adverse Effect").

     (c) AUTHORIZATION; ENFORCEABILITY. The Company has the requisite corporate
power and authority to enter into and to consummate the transactions
contemplated by each of the Transaction Documents and otherwise to carry out its
obligations thereunder. The execution and delivery of each of the Transaction
Documents by the Company and the consummation by it of the transactions
contemplated thereby have been duly authorized by all necessary action on the
part of the Company and no further action is required by the Company in
connection therewith. Each Transaction Document has been (or upon delivery will
have been) duly executed by the Company and, when delivered in accordance with
the terms hereof, will constitute the valid and binding obligation of the
Company enforceable against the Company in accordance with its terms, subject to
laws of general application relating to bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting creditors' rights generally and rules
of law governing specific performance, injunctive relief, or other equitable
remedies.

     (d) NO CONFLICTS. The execution, delivery and performance of the
Transaction Documents by the Company and the consummation by the Company of the
transactions contemplated thereby do not and will not (i) conflict with or
violate any provision of the Company's or any Subsidiary's certificate or
articles of incorporation, bylaws or other organizational or charter documents,
or (ii) conflict with, or constitute a default (or an event that with notice or
lapse of time or both would become a default) under, or give to others any
rights of termination, amendment, acceleration or cancellation (with or without
notice, lapse of time or both) of, any agreement, credit facility, debt or other
instrument (evidencing a Company or Subsidiary debt or otherwise) or other
understanding to which the Company or any Subsidiary is a party or by which any
property or asset of the Company or any Subsidiary is bound or affected, or
(iii) result in a violation of any law, rule, regulation, order, judgment,
injunction, decree or other restriction of any court or governmental authority
to which the Company or a Subsidiary is subject (including federal and state
securities laws and regulations), or by which any property or asset of the
Company or a Subsidiary is bound or affected, except, in the cases of clause
(ii), where such conflict, default or violation would not have or result in a
Material Adverse Effect.

     (e) FILINGS, CONSENTS AND APPROVALS. The Company is not required to obtain
any consent, waiver, authorization or order of, give any notice to, or make any
filing or registration


                                        8



with, any court or other federal, state, local or other governmental authority
or other Person in connection with the execution, delivery and performance by
the Company of the Transaction Documents, other than (a) the filing with the
Commission of the Registration Statement, the application(s) to each Trading
Market for the listing of the Conversion Shares and Warrant Shares for trading
thereon in the time and manner required thereby, Form D and applicable Blue Sky
filings and (b) such as have already been obtained or such exemptive filings as
are required to be made under applicable securities laws.

     (f) ISSUANCE OF THE SECURITIES. The Securities are duly authorized and,
when issued and paid for in accordance with the Transaction Documents, will be
duly and validly issued, fully paid and nonassessable, free and clear of all
Liens, other than any Liens created by or imposed on the holders thereof through
no action of the Company. The Company has reserved from its duly authorized
capital stock the maximum number of shares of Common Stock issuable upon
conversion of the Notes and exercise of the Warrants.

     (g) CAPITALIZATION.

          (i) The authorized and outstanding capitalization of the Company is
set forth on Schedule 3.1(g) hereto. 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. No securities issued by the
Company from March 1, 2002 to the date hereof were issued in violation of any
statutory or common law preemptive rights. There are no dividends which have
accrued or been declared but are unpaid on the capital stock of the Company. All
taxes required to be paid by the Company in connection with the issuance and any
transfers of the Company's capital stock have been paid. The holders of the
Company's Common Stock have certain rights under the company's Rights Agreement
dated as of October 31, 2001 by and between the Company and American Stock
Transfer as Rights Agent. All outstanding securities of the Company have been

contemplated by the Transaction Documents. Except as a result of the purchase
and sale of the Securities and except for employee and director stock options
under the Company's equity compensation plans and as set forth on Schedule
3.1(h)(ii) hereto, there are no outstanding options, warrants, rights to
subscribe to, calls or commitments of any character whatsoever relating to, or
securities, rights or obligations convertible into or exchangeable for, or
giving any Person any right to subscribe for or acquire, any shares of Common
Stock, or contracts, commitments, understandings or arrangements by which the
Company or any Subsidiary is or may become bound to issue additional shares of
Common Stock, or securities or rights convertible or exchangeable into shares of
Common Stock. The issue and sale of the Securities will not obligate the Company
to issue 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.

3.1(i), since June 30, 2006, the Company has conducted its business only in the
ordinary course, consistent with past practice, and since such date there has

reasonably be expected to result in a Material Adverse Effect on the Company or
any of its Subsidiaries;

          (ii) any amendments or changes in the charter documents of the Company

               (A) incurrence, assumption or guarantee by the Company or its
Subsidiaries of any debt for borrowed money other than (i) equipment leases made
in the ordinary course of business, consistent with past practice and (ii) any

                                       12



the terms of all the Governmental Authorizations. The Company and its
Subsidiaries have not engaged in any activity that, to their knowledge, would
cause revocation or suspension of any such Governmental Authorizations. Neither
the execution, delivery nor performance of this Agreement shall adversely affect
the status of any of the Governmental Authorizations.

          (ii) Without limiting the generality of the representations and
warranties made in sub-paragraph (i) above, the Company represents and warrants

     (n) TITLE TO ASSETS. The Company and the Subsidiaries do not own any real
property, and have good and marketable title to all personal property owned by
them that is material to the business of the Company and the Subsidiaries, taken
as a whole, in each case free and clear of all Liens other than those pursuant
to the Security Agreement and except those, if any, reflected in the Company's
financial statements or incurred in the ordinary course of business consistent
with past practice or which would not cause a Material Adverse Effect. Any real
property and facilities held under lease by the Company and the Subsidiaries are
held by them under valid, subsisting and enforceable leases (subject to laws of
general application relating to bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting creditors' rights generally and rules
of law governing specific performance, injunctive relief, or other equitable
remedies) with which the Company and the Subsidiaries are in material
compliance.

     (o) INTELLECTUAL PROPERTY.

          (i) The Company or a Subsidiary thereof has the right to use or is the
sole and exclusive owner of all right, title and interest in and to all material
foreign and domestic patents, patent rights, trademarks, service marks, trade
names, brands and copyrights (whether or not registered and, if applicable,
including pending applications for registration) owned, used or controlled by
the Company and its Subsidiaries (collectively, the "Rights") and in and to each
material invention, software, trade secret, technology, product, composition,
formula and method of process used by the Company or its Subsidiaries (the
Rights and such other items, the "Intellectual Property"), and, to the Company's
knowledge, has the right to use the same, free and clear of any claim or
conflict with the rights of others (subject to the provisions of any applicable
license agreement) except as would not cause a Material Adverse Effect;

          (ii) other than as set forth in the SEC Reports and except as in the
ordinary course of business, no royalties or fees (license or otherwise) are
payable by the Company or its Subsidiaries to any Person by reason of the
ownership or use of any of the Intellectual Property;

          (iii) there have been no written claims made against the Company or
its Subsidiaries asserting the invalidity, abuse, misuse, or unenforceability of
any of the Intellectual Property, and, to the best of the Company's knowledge,
there are no reasonable grounds for any such claims which would cause a Material
Adverse Effect;

          (iv) neither the Company nor its Subsidiaries have made any claim of
any violation or infringement by others of its rights in the Intellectual
Property, and to the best of the Company's knowledge, no reasonable grounds for
such claims exist; and

          (v) neither the Company nor its Subsidiaries have received written
notice that it is in conflict with or infringing upon the asserted rights of
others in connection with the Intellectual Property which would cause a Material
Adverse Effect.

     (p) 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 in the businesses in which the Company and
the Subsidiaries are engaged. All of the insurance policies of the Company and
its Subsidiaries are in full force and effect and are valid and enforceable in
accordance with their terms, and the Company and its Subsidiaries have complied
with all material terms and conditions thereof. Neither the Company nor any
Subsidiary has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business without a significant increase in cost.

     (q) TRANSACTIONS WITH AFFILIATES AND EMPLOYEES. Except as provided in the
SEC Reports, 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 with the Company or any Subsidiary (other than for
services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any 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,

fees for services rendered, (b) reimbursement for expenses incurred on behalf of
the Company and (c) for other employee benefits, including stock option
agreements and other stock awards under any equity compensation plan of the
Company.

     (r) INTERNAL ACCOUNTING CONTROLS. The Company and each of the Subsidiaries
maintains a system of internal accounting controls sufficient in the judgment of
the Company's management 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 GAAP and to maintain asset accountability, (iii)
access to assets is permitted only in accordance with management's general or
specific authorization, and (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. The Company has established disclosure
controls and procedures (as defined in Exchange Act Rules 13a-15(e) and
15d-15(e)) for the Company and designed such disclosure controls and procedures
to ensure that the Company is able to collect the information that it is
required to disclose in the reports it files with the Commission and to process,
summarize and disclose this information in the time periods specified in the
Commission's rules. The Company's certifying officers have evaluated the
effectiveness of the Company's controls and procedures as of June 30, 2006. The
Company presented in its Form 10-Q for the quarter ended June 30, 2006, the
conclusions of the certifying officers about the effectiveness of the disclosure
controls and procedures based on their evaluations as of June 30, 2006. Since
June 30, 2006, there have been no significant changes in the Company's internal
control over financial reporting (as such term is defined in Exchange Act Rule
13a-15) or, to the Company's knowledge, in other factors that could
significantly affect the Company's internal controls.

     (s) CERTAIN FEES. Except for fees payable to SCO Securities LLC, no
brokerage or finder's fees or commissions are or will be payable by the Company
to any broker, financial advisor or consultant, finder, placement agent,
investment banker, bank or other Person with respect to the transactions
contemplated by this Agreement. The Purchasers shall have no obligation with
respect to any fees or with respect to any claims made by or on behalf of other
Persons for fees of a type contemplated in this Section that may be due in
connection with the transactions contemplated by this Agreement.

     (t) PRIVATE PLACEMENT; INTEGRATED OFFERING. Assuming the accuracy of the
Purchasers representations and warranties set forth in Section 3.2, no
registration under the Securities Act is required for the offer and sale of the
Securities by the Company to the Purchasers as contemplated hereby. The issuance
and sale of the Securities hereunder does not contravene the rules and
regulations of the Trading Market. Neither the Company, nor any of its
Affiliates, nor any Person acting on its or their behalf has, directly or
indirectly, made any offers or sales of any security or solicited any offers to
buy any security, under circumstances that would cause this offering of the
Securities to be integrated with prior offerings by the Company for purposes of
the Securities Act and would as a result require registration under the
Securities Act or trigger any applicable shareholder approval provisions,
including, without limitation, under the rules and regulations of any exchange
or automated quotation system on which any of the securities of the Company are
listed or designated.


                                       15



     (u) CHARTER, BYLAWS AND CORPORATE RECORDS. The minute books of the Company
and its Subsidiaries contain in all material respects complete and accurate
records of all meetings and other corporate actions of the board of directors,
committees of the board of directors, incorporators and stockholders of the
Company and its Subsidiaries from the date of incorporation of each such entity
to the date hereof. All material corporate decisions and actions have been
validly made or taken. All corporate books, including without limitation the
share transfer register, comply in all material respects with applicable laws
and regulations and have been regularly updated.

     (v) REGISTRATION RIGHTS. Except as set forth in Schedule 3.1(v), no Person
has any right to cause the Company to effect the registration under the
Securities Act of any securities of the Company.

     (w) LISTING AND MAINTENANCE REQUIREMENTS. Except as set forth on Schedule
3(w), the Company has not, in the 12 months preceding the date hereof, received
notice from any Trading Market on which the Common Stock is or has been listed
or quoted to the effect that the Company is not in compliance with the listing
or maintenance requirements of such Trading Market. The Company is, and has no
reason to believe that it will not in the foreseeable future continue to be, in
compliance with all such listing and maintenance requirements.

     (x) TAXES. All tax returns and tax reports required to be filed with
respect to the income, operations, business or assets of the Company and its
Subsidiaries have been timely filed (or appropriate extensions have been
obtained) with the appropriate governmental agencies in all jurisdictions in
which such returns and reports are required to be filed, and all of the
foregoing as filed are, in all material respects, correct and complete and, in
all material respects, reflect accurately all liability for taxes of the Company
and its Subsidiaries for the periods to which such returns relate, and all
amounts shown as owing thereon have been paid. All income, profits, franchise,
sales, use, value added, occupancy, property, excise, payroll, withholding,
FICA, FUTA and other taxes (including interest and penalties), if any,
collectible or payable by the Company and its Subsidiaries or relating to or
chargeable against any of its material assets, revenues or income or relating to
any employee, independent contractor, creditor, stockholder or other third party
through the Closing Date, were fully collected and paid by such date if due by
such date or provided for by adequate reserves in the financial statements
contained in the SEC Reports as of and for the periods ended June 30, 2006
(other than taxes accruing after such date) and all similar items due through
the Closing Date will have been fully paid by that date or provided for by
adequate reserves, whether or not any such taxes were reported or reflected in
any tax returns or filings. No taxation authority has sought to audit the
records of the Company or any of its Subsidiaries for the purpose of verifying
or disputing any tax returns, reports or related information and disclosures
provided to such taxation authority, or for the Company's or any of its
Subsidiaries' alleged failure to provide any such tax returns, reports or
related information and disclosure. No material claims or deficiencies have been
asserted against or inquiries raised with the Company or any of its Subsidiaries
with respect to any taxes or other governmental charges or levies which have not
been paid or otherwise satisfied, including claims that, or inquiries whether,
the Company or any of its Subsidiaries has not filed a tax return that it was
required to file, and, to the best of the Company's knowledge, there exists no
reasonable basis for the making of any such claims or inquiries. Neither the
Company nor any of its Subsidiaries has waived any restrictions on assessment or
collection of taxes or consented to the extension of any statute of limitations
relating to taxation.


                                       16



     (y) ENVIRONMENTAL MATTERS. None of the premises or any properties owned,
occupied or leased by the Company or its Subsidiaries (the "Premises") has been
used by the Company or the Subsidiaries or, to the Company's knowledge, by any
other Person, to manufacture, treat, store, or dispose of any substance that has
been designated to be a "hazardous substance" under applicable Environmental
Laws (hereinafter defined) ("Hazardous Substances") in violation of any
applicable Environmental Laws. To its knowledge, the Company has not disposed
of, discharged, emitted or released any Hazardous Substances which would
require, under applicable Environmental Laws, remediation, investigation or
similar response activity. No Hazardous Substances are present as a result of
the actions of the Company or, to the Company's knowledge, any other Person, in,
on or under the Premises which would give rise to any liability or clean-up
obligations of the Company under applicable Environmental Laws. The Company and,
to the Company's knowledge, any other Person for whose conduct it may be
responsible pursuant to an agreement or by operation of law, are in compliance
with all laws, regulations and other federal, state or local governmental
requirements, and all applicable judgments, orders, writs, notices, decrees,
permits, licenses, approvals, consents or injunctions in effect on the date of
this Agreement relating to the generation, management, handling, transportation,
treatment, disposal, storage, delivery, discharge, release or emission of any
Hazardous Substance (the "Environmental Laws"). Neither the Company nor, to the
Company's knowledge, any other Person for whose conduct it may be responsible
pursuant to an agreement or by operation of law has received any written
complaint, notice, order, or citation of any actual, threatened or alleged
noncompliance with any of the Environmental Laws, and there is no proceeding,
suit or investigation pending or, to the Company's knowledge, threatened against
the Company or, to the Company's knowledge, any such Person with respect to any
violation or alleged violation of the Environmental Laws, and, to the knowledge
of the Company, there is no basis for the institution of any such proceeding,
suit or investigation.

     (z) DISCLOSURE. The Company confirms that neither the Company nor any other
Person acting on its behalf and at the direction of the Company, has provided
any of the Purchasers or their agents or counsel with any information that in
the Company's reasonable judgment, at the time such information was furnished,
constitutes material, non-public information. The Company understands and
confirms that the Purchasers will rely on the foregoing representations and
covenants in effecting transactions in securities of the Company. All disclosure
provided to the Purchasers regarding the Company, its business and the
transactions contemplated hereby, including the Disclosure Schedules to this
Agreement, furnished by or on behalf of the Company are true and correct in all
material respects and do not contain any untrue statement of a material fact or
omit to state any material fact necessary in order to make the statements made
therein, in light of the circumstances under which they were made, not
misleading.

     (aa) NO ADDITIONAL REPRESENTATIONS. Each Purchaser acknowledges and agrees
that the Company does not make and has not made any representations or
warranties with respect to the transactions contemplated hereby other than those
specifically set forth in this Section 3.1 or in any Transaction Document.

     (bb) POISON PILL. The Company and its Board of Directors have taken all
necessary action, if any, in order to render inapplicable any control share
acquisition, business combination, poison pill (including any distribution under
a rights agreement) or other similar anti-takeover provision under the Company's
Certificate of Incorporation (or similar charter


                                       17



documents) or the laws of its state of incorporation that is or could become
applicable to the Purchasers as a result of the Purchasers and the Company
fulfilling their obligations or exercising their rights under this Agreement and
the Transaction Documents, including without limitation the Company's issuance
of the Securities and the Purchasers' ownership of the Securities.

the representations herein, such Purchaser does not agree to hold any of the
Securities for any minimum or other specific term and reserves the right to
dispose of the Securities at any time in accordance with or pursuant to a

     (f) RELIANCE ON EXEMPTIONS. Such Purchaser understands that the Notes and
Warrants are being offered and sold to it in reliance on specific exemptions
from the registration requirements of United States federal and state securities
laws and that the Company is relying in part upon the truth and accuracy of, and
such Purchaser's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of such Purchaser set forth herein in order
to determine the availability of such exemptions and the eligibility of such
Purchaser to acquire the Common Stock and Warrants.

furnished with all publicly available materials (or such materials have been
made available to such Purchaser) relating to the business, finances and

Such Purchaser understands that its investment in the Notes and Warrants
involves a high degree of risk.

     (h) NO GOVERNMENTAL REVIEW. Such Purchaser understands that no United

has so evaluated the merits and risks of such investment. Such Purchaser is able
to bear the economic risk of an investment in the Notes and Warrants and, at the
present time, is able to afford a complete loss of such investment.

     The Company acknowledges and agrees that each Purchaser does not make or
has not made any representations or warranties with respect to the transactions
contemplated hereby other than those specifically set forth in this Section 3.2.

     (a) The Securities may only be disposed of in compliance with state and
federal securities laws. In connection with any transfer of Securities other
than pursuant to an effective


                                       19



registration statement, to the Company, to an Affiliate of a Purchaser (who is
an accredited investor and executes a customary representation letter) or in
connection with a pledge as contemplated in Section 4.1(b), the Company may
require the transferor thereof to provide to the Company an opinion of counsel
selected by the transferor and reasonably satisfactory to the Company (it being
understood that Wiggin and Dana LLP is reasonably satisfactory), the form and
substance of which opinion shall be reasonably satisfactory to the Company, to
the effect that such transfer does not require registration of such transferred
Securities under the Securities Act, provided, however, that in the case of a
transfer pursuant to Rule 144, no opinion shall be required if the transferor
provides the Company with a customary seller's representation letter, and if
such sale is not pursuant to subsection (k) of Rule 144, a customary broker's
representation letter and a Form 144. Any such transferee that agrees in writing
to be bound by the terms of this Agreement and the Investor Rights Agreement
shall have the rights of a Purchaser under this Agreement and the Investor
Rights Agreement. Except as required by federal securities laws and the
securities law of any state or other jurisdiction within the United States, the
Securities may be transferred, in whole or in part, by any of the Purchasers at
any time. The Company shall reissue certificates evidencing the Securities upon
surrender of certificates evidencing the Securities being transferred in
accordance with this Section 4.1(a).

     (b) The Purchasers agree to the imprinting, so long as is required by this
Section 4.1(b), of a legend on any of the Securities in substantially the
following form:

     THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE
COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN
EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
"SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT
TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO
AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO
THE TRANSFEROR TO SUCH EFFECT, SUCH COUNSEL AND THE SUBSTANCE OF SUCH OPINION
SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. UNLESS PROHIBITED BY APPLICABLE
LAW, RULE OR REGULATION, THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A
BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A
FINANCIAL INSTITUTION THAT IS AN "ACCREDITED INVESTOR" AS DEFINED IN RULE 501(a)
UNDER THE SECURITIES ACT.

     The Company acknowledges and agrees that, unless prohibited by applicable
law, rule or regulation, a Purchaser may from time to time pledge pursuant to a
bona fide margin agreement with a registered broker-dealer or grant a security
interest in some or all of the Securities to a financial institution that is an
"accredited investor" as defined in Rule 501(a) under the Securities Act and, if
required under the terms of such arrangement, such Purchaser may transfer
pledged or secured Securities to the pledgees or secured parties. Such a pledge
or transfer would not be subject to approval of the Company and no legal opinion
of legal counsel of the pledgee, secured party or pledgor shall be required in
connection therewith; provided, however, that such Purchaser shall provide the
Company with such documentation as is reasonably requested by the Company to
ensure that the pledge is pursuant to a bona fide margin


                                       20



agreement with a registered broker-dealer or a security interest in some or all
of the Securities to a financial institution that is an "accredited investor" as
defined in Rule 501(a) under the Securities Act. The Company will execute and
deliver such documentation as a pledgee or secured party of Securities may
reasonably request in connection with a pledge or transfer of the Securities,
including the preparation and filing of any required prospectus supplement under
Rule 424(b)(3) under the Securities Act or other applicable provision of the
Securities Act to appropriately amend the list of selling stockholders
thereunder.

     (c) Certificates evidencing the Conversion Shares and Warrant Shares shall
not contain any legend (including the legend set forth in Section 4.1(b)), (i)
following any sale of such Conversion Shares or Warrant Shares pursuant to Rule
144, or (ii) if such Conversion Shares or Warrant Shares are eligible for sale
under Rule 144(k) (and the holder of such Conversion 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 (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 Conversion 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 hereunder and shall also cause its
counsel to issue a "blanket" legal opinion to the Company's transfer agent
promptly after the Effective Date, if required by the Company's transfer agent,
to allow sales pursuant to an effective Registration Statement. The Company
agrees that at such time as such legend is no longer required under this Section
4.1(c), it will, no later than three Trading Days following the delivery by a
Purchaser to the Company or the Company's transfer agent of a certificate
representing Conversion Shares or Warrant Shares, as the case may be, issued
with a restrictive legend, deliver or cause to be delivered to such Purchaser a
certificate representing such Securities that is free from all restrictive and
other legends; provided that the holder of such Conversion 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.

     (d) Each Purchaser, severally and not jointly, agrees that the removal of
the restrictive legend from certificates representing Securities as set forth in
this Section 4.1 is predicated upon the Company's reliance on, and the
Purchaser's agreement that, and each Purchaser hereby agrees that, the Purchaser
will not sell any Securities except pursuant to either the registration
requirements of the Securities Act, including any applicable prospectus delivery
requirements, or an exemption therefrom.

     4.2 FURNISHING OF INFORMATION.

     As long as any Purchaser owns Securities, 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 after the date
hereof pursuant to the Exchange Act. Upon the request of any such holder of
Securities, the Company shall deliver to such holder a written certification of
a duly authorized officer as to whether it has complied with the preceding


                                       21



sentence. As long as any Purchaser owns Securities, if the Company is not
required to file reports pursuant to the Exchange Act, it will prepare and
furnish to the Purchasers and make publicly available in accordance with Rule
144(c), such information as is required for the Purchasers to sell the
Securities under Rule 144. The Company further covenants that it will take such
further action as any holder of Securities may reasonably request, all to the
extent required from time to time to enable such Person to sell such Securities
without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144.

     4.3 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
Securities in a manner that would require the registration under the Securities
Act of the sale of the Securities to the Purchasers or that would be integrated
with the offer or sale of the Securities for purposes of the rules and
regulations of any Trading Market.

     4.4 PUBLICITY.

     The Company shall, within two Business Days following the Closing Date,
file a Current Report on Form 8-K, disclosing the transactions contemplated
hereby and make such other filings and notices in the manner and time required
by the Commission. The Company and SCO Securities LLC shall consult with each
other in issuing any press releases with respect to the transactions
contemplated hereby, and neither the Company nor any Purchaser nor SCO
Securities LLC shall issue any such press release or otherwise make any such
public statement without the prior consent of the Company, with respect to any
press release of any Purchaser or SCO Securities LLC, or without the prior
consent of SCO Securities LLC, with respect to any press release of the Company,
except if such disclosure is required by applicable law, rule or regulation, in
which case the disclosing party shall promptly provide the other party with
prior notice of such public statement or communication.

     4.5 USE OF PROCEEDS.

     The Company covenants and agrees that the proceeds from the sale of the
Notes and Warrants shall be used by the Company for working capital and general
corporate purposes; under no circumstances shall any portion of the proceeds be
applied to:

          (i)   accelerated repayment of debt existing on the date hereof (other
                than payment of trade payables in the ordinary course of the
                Company's business and consistent with prior practices);

          (ii)  the payment of dividends or other distributions on any capital
                stock of the Company;

          (iii) the purchase of debt or equity securities of any Person for
                cash, including the Company and its Subsidiaries, 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;

          (iv)  any expenditure not directly related to the business of the
                Company; or


                                       22



          (v)   the redemption of any Company equity or equity-equivalent
                securities.

     4.6 RESERVATION OF COMMON STOCK.

     As of the date hereof, the Company has reserved and the Company shall
continue to reserve and keep available at all times, free of preemptive rights,
a sufficient number of shares of Common Stock for the purpose of enabling the
Company to issue the maximum number of Conversion Shares issuable upon
conversion of the Notes and Warrant Shares issuable upon exercise of the
Warrants.

     4.7 LISTING OF COMMON STOCK.

     The Company hereby agrees that, from time to time, if the Company applies
to have the Common Stock traded on any Trading Market, it will include in such
application the Conversion Shares and the Warrant Shares, and will take such
other action as is necessary to cause the Conversion Shares and Warrant Shares
to be listed on such Trading Market as promptly as possible.

     4.8 BUSINESS OPERATIONS. Until the earlier of: (i) the third year
anniversary of the Closing Date and (ii) the date that the Purchasers own less
than 50% of the Notes originally issued pursuant to this Agreement or Conversion
Shares issuable upon conversion thereof, the Company shall comply with the
following covenants:

     (a) INSURANCE. The Company and its Subsidiaries shall maintain insurance
policies such that the representations contained in the first sentence of
Section 3.1(p) hereof continue to be true and correct and shall, from time to
time upon the written request of the Purchasers, promptly furnish or cause to be
furnished to the Purchasers evidence, in form and substance reasonably
satisfactory to the Purchasers, of the maintenance of all insurance maintained
by it.

     (b) CORPORATE EXISTENCE; LICENSES. The Company shall preserve and maintain
and cause its Subsidiaries to preserve and maintain their corporate existence
and good standing in the jurisdiction of their incorporation and the rights,
privileges and franchises of the Company and its Subsidiaries (except, in each
case, in the event of a merger or consolidation in which the Company or its
Subsidiaries, as applicable, is not the surviving entity) in each case where the
failure to so preserve or maintain could have a Material Adverse Effect on the
financial condition, business or operations of the Company and its Subsidiaries
taken as a whole. The Company shall, and shall cause its Subsidiaries to,
maintain at all times all material licenses or permits necessary to the conduct
of its business and as required by any governmental agency or instrumentality
thereof, including without limitation all Food and Drug Administration
clearances and approvals.

     (c) TAXES AND CLAIMS. The Company and its Subsidiaries shall duly pay and
discharge (a) all taxes, assessments and governmental charges upon or against
the Company or its properties or assets prior to the date on which penalties
attach thereto, unless and to the extent that such taxes are being diligently
contested in good faith and by appropriate proceedings, and appropriate reserves
therefor have been established, and (b) all lawful claims, whether for labor,
materials, supplies, services or anything else which might or could, if unpaid,
become a lien or charge upon the properties or assets of the Company or its
Subsidiaries, unless and to the extent


                                       23



only that the same are being contested in good faith and by appropriate
proceedings and appropriate reserves therefor have been established.

     (d) AFFILIATE TRANSACTIONS. Except for transactions approved by the
Company's Audit Committee or a majority of the disinterested members of the
board of directors of the Company, neither the Company nor any of its
Subsidiaries shall enter into any transaction with any (i) director, officer,
employee or holder of more than 5% of the outstanding capital stock of any class
or series of capital stock of the Company or any of its Subsidiaries, (ii)
member of the immediate family of any such person, or (iii) corporation,
partnership, trust or other entity in which any such person, or member of the
immediate family of any such person, is a director, officer, trustee, partner or

     (a) SECURITIES ACT. The Company shall timely prepare and file with the
Securities and Exchange Commission the form of notice of the sale of securities
pursuant to the requirements of Regulation D regarding the sale of the Common
Stock and Warrants under this Agreement.

     (b) STATE SECURITIES LAW COMPLIANCE -- SALE. The Company shall timely

Shares and Warrant Shares under a registration statement pursuant to the
Investor Rights Agreement or (ii) the Common Stock becomes a "covered security"

updated listing containing (i) the names of the officers and directors of the
Company, (ii) a balance sheet of the Company as of a date that is at no time
older than eighteen months and (iii) a profit and loss statement of the Company

agreement) or other similar anti-takeover provision under the Company's
Certificate of Incorporation (or similar charter documents) or the laws of its
state of incorporation that is or could become applicable to the Purchasers as a
result of the Purchasers and the Company fulfilling their obligations or
exercising their rights under this Agreement and the Transaction Documents,
including without limitation the Company's issuance of the Securities and the
Purchasers' ownership of the Securities.


                                       24



     4.11 DIRECTOR DESIGNEES. For as long as the Notes issued pursuant to this

                    INDEMNIFICATION, TERMINATION AND DAMAGES

     5.1 SURVIVAL OF REPRESENTATIONS.

     Except as otherwise provided herein, the representations and warranties of
the Company and the Purchasers contained in or made pursuant to this Agreement
shall survive the execution and delivery of this Agreement and the Closing Date
and shall continue in full force and effect for a period of one (1) year from
the Closing Date. The Company's and the Purchasers' warranties and
representations shall in no way be affected or diminished in any way by any
investigation of (or failure to investigate) the subject matter thereof made by
or on behalf of the Company or the Purchasers.

     5.2 INDEMNIFICATION.

     (a) The Company agrees to indemnify and hold harmless the Purchasers, their
Affiliates, each of their officers, directors, employees and agents and their
respective successors and assigns, from and against any losses, damages, or
expenses which are caused by or arise out of (i) any breach or default in the
performance by the Company of any covenant or agreement made by the Company in
this Agreement or in any of the Transaction Documents; (ii) any breach of
warranty or representation made by the Company in this Agreement or in any of
the Transaction Documents; and/or (iii) any and all third party actions, suits,
proceedings, claims, demands, judgments, costs and expenses (including
reasonable legal fees and expenses) incident to any of the foregoing.

     (b) The Purchasers, severally and not jointly, agree to indemnify and hold
harmless the Company, its Affiliates, each of their officers, directors,
employees and agents and their respective successors and assigns, from and
against any losses, damages, or expenses which are caused by or arise out of (A)
any breach or default in the performance by the Purchasers of any covenant or
agreement made by the Purchasers in this Agreement or in any of the Transaction
Documents; (B) any breach of warranty or representation made by the Purchasers
in this Agreement or in any of the Transaction Documents; and (C) any and all
third party actions, suits, proceedings, claims, demands, judgments, costs and
expenses (including reasonable legal fees and expenses) incident to any of the
foregoing; provided, however, that a Purchaser's liability under this Section
5.2(b) shall not exceed the Purchase Price paid by such Purchaser hereunder.

     5.3 INDEMNITY PROCEDURE.

     A party or parties hereto agreeing to be responsible for or to indemnify
against any matter pursuant to this Agreement is referred to herein as the
"Indemnifying Party" and the other


                                       25



party or parties claiming indemnity is referred to as the "Indemnified Party".
An Indemnified Party under this Agreement shall, with respect to claims asserted
against such party by any third party, give written notice to the Indemnifying
Party of any liability which might give rise to a claim for indemnity under this
Agreement within sixty (60) Business Days of the receipt of any written claim
from any such third party, but not later than twenty (20) days prior to the date
any answer or responsive pleading is due, and with respect to other matters for
which the Indemnified Party may seek indemnification, give prompt written notice
to the Indemnifying Party of any liability which might give rise to a claim for
indemnity; provided, however, that any failure to give such notice will not
waive any rights of the Indemnified Party except to the extent the rights of the
Indemnifying Party are materially prejudiced.

     The Indemnifying Party shall have the right, at its election, to take over
the defense or settlement of such claim by giving written notice to the
Indemnified Party at least fifteen (15) days prior to the time when an answer or
other responsive pleading or notice with respect thereto is required. If the
Indemnifying Party makes such election, it may conduct the defense of such claim
through counsel of its choosing (subject to the Indemnified Party's approval of
such counsel, which approval shall not be unreasonably withheld or delayed),
shall be solely responsible for the expenses of such defense and shall be bound
by the results of its defense or settlement of the claim. The Indemnifying Party
shall not settle any such claim without prior notice to and consultation with
the Indemnified Party, and no such settlement involving any equitable relief or
which might have an adverse effect on the Indemnified Party may be agreed to
without the written consent of the Indemnified Party (which consent shall not be
unreasonably withheld or delayed). So long as the Indemnifying Party is
diligently contesting any such claim in good faith, the Indemnified Party may
pay or settle such claim only at its own expense and the Indemnifying Party will
not be responsible for the fees of separate legal counsel to the Indemnified
Party, unless the named parties to any proceeding include both parties or
representation of both parties by the same counsel would be inappropriate in the
reasonable opinion of counsel to the Indemnified Party, due to conflicts of
interest or otherwise. If the Indemnifying Party does not make such election, or
having made such election does not, in the reasonable opinion of the Indemnified
Party proceed diligently to defend such claim, then the Indemnified Party may
(after written notice to the Indemnifying Party), at the expense of the
Indemnifying Party, elect to take over the defense of and proceed to handle such
claim in its discretion and the Indemnifying Party shall be bound by any defense
or settlement that the Indemnified Party may make in good faith with respect to
such claim. In connection therewith, the Indemnifying Party will fully cooperate
with the Indemnified Party should the Indemnified Party elect to take over the
defense of any such claim. The parties agree to cooperate in defending such
third party claims and the Indemnified Party shall provide such cooperation and
such access to its books, records and properties (subject to the execution of
appropriate non-disclosure agreements) as the Indemnifying Party shall
reasonably request with respect to any matter for which indemnification is
sought hereunder; and the parties hereto agree to cooperate with each other in
order to ensure the proper and adequate defense thereof.

     With regard to claims of third parties for which indemnification is payable
hereunder, such indemnification shall be paid by the Indemnifying Party upon the
earlier to occur of: (i) the entry of a judgment against the Indemnified Party
and the expiration of any applicable appeal period, or if earlier, five (5) days
prior to the date that the judgment creditor has the right to execute the
judgment; (ii) the entry of an unappealable judgment or final appellate decision
against the Indemnified Party; or (iii) a settlement of the claim.
Notwithstanding the foregoing,


                                       26



the reasonable expenses of counsel to the Indemnified Party shall be reimbursed
on a current basis by the Indemnifying Party. With regard to other claims for
which indemnification is payable hereunder, such indemnification shall be paid
promptly by the Indemnifying Party upon demand by the Indemnified Party.

                                   ARTICLE VI

                                  MISCELLANEOUS

instrument signed, in the case of an amendment, by the Company and each
Purchaser or, in the case of a waiver, by the party against whom enforcement of
any such waiver is sought. No waiver of any default with respect to any
provision, condition or requirement of this Agreement shall be deemed to be a
continuing waiver in the future or a waiver of any subsequent default or a
waiver of any other provision, condition or requirement hereof, nor shall any
delay or omission of either party to exercise any right hereunder in any manner
impair the exercise of any such right.

     6.9 JURISDICTION; VENUE; SERVICE OF PROCESS.

     This Agreement shall be subject to the exclusive jurisdiction of the
Federal District Court, Southern District of New York and if such court does not
have proper jurisdiction, the State Courts of New York County, New York. The
parties to this Agreement agree that any breach of any term or condition of this
Agreement shall be deemed to be a breach occurring in the State of New York by
virtue of a failure to perform an act required to be performed in the State of
New York and irrevocably and expressly agree to submit to the jurisdiction of
the Federal District Court, Southern District of New York and if such court does
not have proper jurisdiction, the State Courts of New York County, New York for

arising out of or relating to this Agreement, or any judgment entered by any
court in respect hereof brought in New York County, New York, and further
irrevocably waive any claim that any suit, action or proceeding brought in

brought in an inconvenient forum. Each of the parties hereto consents to process
being served in any such suit, action or proceeding, by mailing a copy thereof
to such party at the address in effect for notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of
process and notice thereof. Nothing in this Section 6.9 shall affect or limit
any right to serve process in any other manner permitted by law.

     6.10 EXECUTION.

     This Agreement may be executed in two or more counterparts, all of which
when taken together shall be considered one and the same agreement and shall
become effective when counterparts have been signed by each party and delivered
to the other party, it being understood that both parties need not sign the same
counterpart. In the event that any signature is delivered by facsimile
transmission, such signature shall create a valid and binding obligation of the
party executing (or on whose behalf such signature is executed) with the same
force and effect as if such facsimile signature page were an original thereof.

     6.11 SEVERABILITY.

     If any provision of this Agreement is held to be invalid or unenforceable
in any respect, the validity and enforceability of the remaining terms and
provisions of this Agreement shall not in any way be affected or impaired
thereby and the parties will attempt to agree upon a valid and enforceable
provision that is a reasonable substitute therefor, and upon so agreeing, shall
incorporate such substitute provision in this Agreement.

     6.12 REPLACEMENT OF SECURITIES.

     If any certificate or instrument evidencing any of the Securities is
mutilated, lost, stolen or destroyed, the Company shall issue or cause to be
issued in exchange and substitution for and upon cancellation thereof, or in
lieu of and substitution therefor, a new certificate or instrument, but only
upon receipt of evidence reasonably satisfactory to the Company of such loss,
theft or


                                       29



destruction and customary and reasonable indemnity (but no bond shall be
required), if requested by the Company.

     6.13 REMEDIES.

     In addition to being entitled to exercise all rights provided herein or
granted by law, including recovery of damages, each of the Purchasers and the
Company will be entitled to specific performance under the Transaction
Documents. The parties agree that monetary damages may not be adequate
compensation for any loss incurred by reason of any breach of obligations
described in the foregoing sentence and hereby agrees to waive in any action for
specific performance of any such obligation the defense that a remedy at law
would be adequate.

     6.14 PAYMENT SET ASIDE.

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

     6.15 INDEPENDENT NATURE OF PURCHASERS' OBLIGATIONS AND RIGHTS.

     The obligations of each Purchaser under any Transaction Document are
several and not joint with the obligations of any other Purchaser, and no
Purchaser shall be responsible in any way for the performance of the obligations
of any other Purchaser under any Transaction Document. Nothing contained herein
or in any Transaction Document, and no action taken by any Purchaser pursuant
thereto, shall be deemed to constitute the Purchasers as a partnership, an
association, a joint venture or any other kind of entity, or create a
presumption that the Purchasers are in any way acting in concert or as a group
with respect to such obligations or the transactions contemplated by the
Transaction Document. Each Purchaser 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 Purchaser to be joined as an additional party in any
proceeding for such purpose. Each Purchaser has been represented by its own
separate legal counsel in their review and negotiation of the Transaction
Documents. For reasons of administrative convenience only, Purchasers and their
respective counsel have chosen to communicate with the Company through Wiggin
and Dana LLP, but such counsel does not represent any of the Purchasers in this
transaction other than SCO Securities LLC. The Company has elected to provide
all Purchasers 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
Purchasers.

     6.16 WAIVER OF TRIAL BY JURY.

     THE PARTIES HERETO IRREVOCABLY WAIVE TRIAL BY JURY IN ANY SUIT, ACTION OR
PROCEEDING RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

     6.17 FURTHER ASSURANCES.

     Each party agrees to cooperate fully with the other parties and to execute
such further instruments, documents and agreements and to give such further
written assurances as may be reasonably requested by any other party to better
evidence and reflect the transactions described herein and contemplated hereby
and to carry into effect the intents and purposes of this Agreement, and further
agrees to take promptly, or cause to be taken, all actions, and to do promptly,
or cause to be done, all things necessary, proper or advisable under applicable
law to consummate and make effective the transactions contemplated hereby, to
obtain all necessary waivers, consents and approvals, to effect all necessary
registrations and filings, and to remove any injunctions or other impediments or
delays, legal or otherwise, in order to consummate and make effective the
transactions contemplated by this Agreement for the purpose of securing to the
parties hereto the benefits contemplated by this Agreement.

                    7.5% SECURED CONVERTIBLE PROMISSORY NOTE

U.S. $____________                                                 DALLAS, TEXAS
NO.: PN-2006-__                                                OCTOBER ___, 2006

          FOR VALUE RECEIVED, the undersigned, Access Pharmaceuticals, Inc., a
Delaware corporation (the "Company"), hereby promises to pay to the order of
_________ or any future holder of this promissory note (the "Payee"), at the
principal office of the Payee set forth herein, or at such other place as the
holder may designate in writing to the Company, the principal sum of
_____________ Dollars (U.S. $__________) (the "Principal Amount"), or such other
amount as may be outstanding hereunder, together with all accrued but unpaid
interest, in such coin or currency of the United States of America as at the
time shall be legal tender for the payment of public and private debts and in
immediately available funds, as provided in this promissory note (the "Note").

     This Note is one of a duly authorized issue of 7.5% Secured Convertible
Promissory Notes of the Company, in aggregate principal amount of up to Five
Hundred Thousand Dollars ($500,000) (the "Promissory Notes") issued pursuant to
the Convertible Note and Warrant Purchase Agreement of even date herewith (the
"Purchase Agreement"). The Promissory Notes rank equally and ratably without
priority over one another. No payment, including any prepayment, shall be made
hereunder unless payment, including any prepayment, is offered with respect to
the other Promissory Notes in an amount which bears the same ratio to the then
unpaid principal amount of such Promissory Notes as the payment made hereon
bears to the then unpaid principal amount under this Note.

          1. Principal and Interest Payments.

               (a) The Company shall repay in full the entire principal balance
then outstanding under this Note plus all accrued and unpaid interest on the
first to occur (the



"Maturity Date") of: (i) March 31, 2007; (ii) such time as there occurs a Sale
Transaction (as defined below) unless the resulting successor or acquiring
entity in such Sale Transaction (if not the Company) and, if an entity different
from the successor or acquiring entity, the entity whose capital stock or assets
the holders of the Common Stock are entitled to receive as a result of such Sale
Transaction, (A) assumes by written instrument all of the obligations of the
Promissory Notes and the Transaction Documents (as defined in the Purchase
Agreement) as more fully set forth in Section 1(d) below and (B) the entity
whose securities into which this Note shall become convertible in such
transaction is a publicly traded corporation whose common stock is listed for
trading on the New York Stock Exchange, the American Stock Exchange, the Nasdaq
National Market, the Nasdaq Capital Market, the OTC Bulletin Board or Pink
Sheets or (iii) the acceleration of the obligations as contemplated by this
Note.

     "Sale Transaction" shall mean any transaction or series of related
transactions, other than the conversion of convertible securities of the Company
outstanding as of the date hereof or the exercise of options or warrants of the
Company, in each case, outstanding as of the date hereof, which result in the
(i) acquisition by an individual or legal entity or group (as set forth in
Section 13(d) of the Exchange Act) of more than one-half of the voting rights or
equity interests in the Company; or (ii) sale, conveyance, or other disposition
of all or substantially all of the assets, property or business of the Company
or the merger into or consolidation with any other corporation (other than a
wholly owned subsidiary corporation) or effectuation of any transaction or
series of related transactions where holders of the Company's voting securities
prior to such transaction or series of transactions fail to continue to hold at
least 50% of the voting power of the Company (or, if other than the Company, the
successor or acquiring entity) immediately following such transaction.

               (b) Interest on the outstanding principal balance of this Note
shall accrue at a rate of seven and one-half percent (7.5%) per annum,
compounded quarterly. Interest on the outstanding principal balance of the Note
shall be computed on the basis of the actual number of days elapsed and a year
of three hundred and sixty (360) days and shall be payable on the Maturity Date,
upon earlier prepayment of this Note or in the form of shares of common stock,
par value $0.01 per share, of the Company (the "Common Stock") upon conversion
of this note as set forth in Section 8 below. Furthermore, upon the occurrence
of an Event of Default, then to the extent permitted by law, the Company will
pay interest to the Payee, payable on demand, on the outstanding principal
balance of the Note from the date of the Event of Default until payment in full
at the rate of twelve percent (12%) per annum.

               (c) The Company may not prepay the outstanding principal amount
of this Note or the interest thereon prior to the Maturity Date (a "Prepayment")
without the written consent of the Payee, unless the Company shall provide at
least sixty (60) days, but not more than ninety (90) days, prior written notice
of the date on which the Company intends to make such Prepayment (a "Prepayment
Notice"). Nothing in this Section 1(c) shall limit the right of the Payee to
convert this Note into Common Stock at any time after receipt of the Prepayment
Notice and prior to the time at which such Prepayment is made. Notwithstanding
the limitations in Section 8(g), the Payee may deliver a Conversion Notice with
respect to all of the outstanding Principal Amount and interest accrued thereon,
in which case, to the extent that Section 8(g)


                                       2



limits the conversion of this Note, this Note shall not be subject to Prepayment
and shall be converted as set forth in Section 8(c)(v).

               (d) If the Promissory Notes and Transaction Documents are to be
assumed as described in Section 1(a)(ii)(A), the applicable assuming corporation
shall expressly assume the due and punctual observance and performance of each
and every covenant and condition contained in the Promissory Notes and the
Transaction Documents to be performed and observed by the Company and all the
obligations and liabilities thereunder, subject to such modifications as may be
deemed appropriate (as determined by resolution of the Board of Directors of the
Company) in order to provide for adjustments of shares of the Common Stock into
which the Promissory Notes are convertible which shall be as nearly equivalent
as practicable to the adjustments provided for in Section 8. The provisions of
Section 1(a) and this Section 1(d) shall similarly apply to successive Sale
Transactions.

          2. Non-Business Days. Whenever any payment to be made shall be due on
a Saturday, Sunday or a public holiday under the laws of the State of Texas,
such payment may be due on the next succeeding business day and such next
succeeding day shall be included in the calculation of the amount of accrued
interest payable on such date.

          3. Security. This Note is secured pursuant to the terms of a Security
Agreement dated as of February 16, 2006, between the Company and the holders of
the Secured Convertible Promissory Notes issued by the Company on February 16,
2006 (the "February Notes") as amended pursuant to a Security Agreement
Amendment between the Company, the holders of the February Notes and the holders
of the Promissory Notes, of even date herewith (such Security Agreement, as so
amended, the "Security Agreement") by a security interest in the Collateral (as
such term is defined in the Security Agreement). The Note is subject to the
provisions of the Security Agreement.

          4. Subordination of Future Debt; Payment of Common Stock Dividends.
Any debt incurred after the date hereof to any creditor shall be subordinated to
the indebtedness evidenced by this Note. The Company shall not declare or pay
any dividend or distribution with respect to any common stock of the Company
other than a pro rata dividend payable solely in shares of Common Stock.

          5. Representations and Warranties of the Company. The Company
represents and warrants to the Payee as follows:

creditors' rights generally, and the Company has full power and authority to
execute and deliver this Note and to perform its obligations hereunder.

               (c) The execution, delivery and performance of this Note will not
(i) conflict with or result in a breach of or a default under any of the terms

declaration or filing with any governmental authority on the part of the Company
is required in connection with the valid execution and delivery of this Note.

such payment shall become due and payable hereunder; or

between the Company and the Payee relating to indebtedness of the Company to the
Payee or any of its affiliates for borrowed money and such default shall have
continued for a period of five (5) days after Company's receipt of written
notice of such default (unless such default is on account of failure to give a
required notice, in which event such 5 day cure period shall commence with the
date of such default); or

               (d) the holder of any indebtedness of the Company or any of its
subsidiaries shall accelerate any payment of any amount or amounts of principal

amount of which Indebtedness of all such persons is in excess of $100,000,
whether such Indebtedness now exists or shall hereafter be created, and such
accelerated payment entitles the holder thereof to immediate payment of such


                                        4



Indebtedness which is due and owing and such indebtedness has not been

(60) consecutive days following entry of the judgment or order in excess of
$100,000 or the judgment or order which causes the aggregate amount described
above to exceed $100,000 during which a stay of enforcement of such judgment or
order, by reason of a pending appeal or otherwise, shall not be in effect; or

               (f) the Company shall (i) apply for or consent to the appointment
of, or the taking of possession by, a receiver, custodian, trustee or liquidator
of itself or of all or a substantial part of its property or assets, (ii) make a

court of competent jurisdiction, seeking (i) the liquidation, reorganization,
moratorium, dissolution, winding up, or composition or readjustment of its
debts, (ii) the appointment of a trustee, receiver, custodian, liquidator or the
like of it or of all or any substantial part of its assets or (iii) similar

Bankruptcy Code or under the comparable laws of any jurisdiction (foreign or

               (h) the suspension from listing or the failure of the Company's

American Stock Exchange, New York Stock Exchange, Nasdaq National Market or
Nasdaq Capital Market for a period of five (5) consecutive trading days;


                                       5



               (i) the declaration or payment by the Company of any dividend or
distribution with respect to its common stock other than a pro rata dividend
payable solely in shares of Common Stock; or

               (j) the failure by the Company to comply with the requirements of
Section 4.11 of the Purchase Agreement.

          7. Remedies Upon An Event of Default. If an Event of Default shall
have occurred and shall be continuing, the Payee of this Note may at any time at
its option, (a) declare the entire unpaid principal balance of this Note,
together with all interest accrued hereon, due and payable, and thereupon, the
same shall be accelerated and so due and payable; provided, however, that upon
the occurrence of an Event of Default described in (i) Sections 6(f) and (g),
without presentment, demand, protest, or notice, all of which are hereby
expressly unconditionally and irrevocably waived by the Company, the outstanding
principal balance and accrued interest hereunder shall be automatically due and
payable, and (ii) Sections 6(a) through (e) and Sections 6(h) through (j), the
Payee may exercise or otherwise enforce any one or more of the Payee's rights,
powers, privileges, remedies and interests under this Note or applicable law. No
course of delay on the part of the Payee shall operate as a waiver thereof or
otherwise prejudice the right of the Payee. No remedy conferred hereby shall be
exclusive of any other remedy referred to herein or now or hereafter available
at law, in equity, by statute or otherwise.

          8. Conversion.

          (a) Optional Conversion. Subject to the limitations set forth in
Sections 8(g) hereof, the holder of this Note shall have the right at any time,
at such holder's option, to convert all or any lesser portion of the Principal
Amount plus accrued and unpaid interest thereon into such number of fully paid
and non-assessable shares of Common Stock as is determined by dividing (i) the
portion of the Principal Amount to be converted plus accrued and unpaid interest
thereon by (ii) the Conversion Rate (as defined below) then in effect for this
Note. The initial conversion rate shall be $1.10, such rate to be subject to
adjustment in accordance with the provisions of this Section 8. Such conversion
rate in effect from time to time, as adjusted pursuant to this Section 8, is
referred to herein as a "Conversion Rate." All of the remaining provisions of
this Section 8 shall apply separately to each Conversion Rate in effect from
time to time with respect to this Note.

          (b) Mandatory Conversion. If a Conversion Triggering Event (as defined
below) shall occur and within 5 business days following such occurrence, the
Company shall deliver a written notice to the holders of the Promissory Notes
(the "Notice") that the Company intends to convert all of the outstanding
Promissory Notes into Common Stock, then, subject to the limitations set forth
in Section 8(g) hereof, as of the date that is sixty-five days following the
date that such Notice is given (the "Mandatory Conversion Date"), this Note
shall be converted into such number of fully paid and non-assessable shares of
Common Stock as is determined by dividing (i) the Principal Amount plus accrued
and unpaid interest thereon by (ii) the Conversion Rate then in effect (the
"Mandatory Conversion"). Nothing in this Section 8(b) shall be construed so as
to limit the right of a holder of this Note to convert pursuant to Section 8(a)
at any time. If the Maturity Date occurs after the Notice is duly delivered to
the Payee, but prior to


                                       6



the Mandatory Conversion Date or the earlier conversion in full of this Note,
then the Company shall not be obligated to repay in cash the Principal Amount,
together with all accrued and unpaid interest thereon, and this Note shall
remain outstanding, as more fully described in Section 8(c)(v), until such time
as it is fully converted.

          "Conversion Triggering Event" shall mean, such time as:

               (i) The Registration Statement (as defined below) covering all of
     the shares of Common Stock into which this Note is convertible is effective
     and sales may be made pursuant thereto (or all of the shares of Common
     Stock into which this Note is convertible may be sold without restriction
     pursuant to Rule 144(k) promulgated by the Securities and Exchange
     Commission under the Securities Act of 1933, as amended (the "Securities
     Act"));

               (ii) The Daily Market Price of the Common Stock is at least $7.50
     (subject to adjustment for stock splits, reverse splits, stock dividends
     and the like) for any period of 20 consecutive trading days; and

               (iii) The Company has a sufficient number of authorized and
     unissued shares of Common Stock reserved for issuance upon the conversion
     of the Promissory Notes to convert all of the Promissory Notes in full.

     "Registration Statement" shall have the meaning established in the Investor
Rights Agreement dated on or about the date hereof, by and among the Company and
the other parties signatory thereto.

          (c) Mechanics of Conversion.

          (i) Such right of conversion shall be exercised by the Payee by
delivering to the Company a conversion notice in the form attached hereto as
Exhibit A (the "Conversion Notice"), appropriately completed and duly signed,
and by surrender not later than two (2) business days thereafter of this Note.
The Conversion Notice shall also contain a statement of the name or names (with
addresses and tax identification or social security numbers) in which the
certificate or certificates for Common Stock shall be issued, if other than the
name in which this Note is registered. Promptly after the receipt of the
Conversion Notice, the Company shall issue and deliver, or cause to be
delivered, to the Payee or such Payee's nominee, a certificate or certificates
for the number of shares of Common Stock issuable upon such conversion. Such
conversion shall be deemed to have been effected as of the close of business on
the date of receipt by the Company of the Conversion Notice (the "Conversion
Date"), and the person or persons entitled to receive the shares of Common Stock
issuable upon conversion shall be treated for all purposes as the holder or
holders of record of such shares of Common Stock as of the close of business on
the Conversion Date. If the Payee has not converted the entire amount of the
Note pursuant to the Conversion Notice, then the Company shall execute and
deliver to the Payee a new Note instrument identical in terms to this Note, but
with a principal amount reflecting the unconverted portion of this Note. The new
Note instrument shall be delivered subject to the same timing terms as the
certificates for the Common Stock.


                                       7



          (ii) The Company shall effect such issuance of Common Stock within
three (3) trading days following the Conversion Date and shall transmit the
certificates by messenger or reputable overnight delivery service to reach the
address designated by such holder within three (3) trading days after the
receipt by the Company of such Conversion Notice. Provided that the holder
complies with all of the provisions of this Note relating to the conversion
hereof, if certificates evidencing the Common Stock are not received by the
holder (through no fault or negligence of the holder) within five (5) Business
Days following the Conversion Date, then the holder will be entitled to revoke
and withdraw its Conversion Notice, in whole or in part, at any time prior to
its receipt of those certificates. If the conversion has not been rescinded in
accordance with this paragraph and the Company fails to deliver to the holder
such certificate or certificates pursuant to this Section 8 in accordance
herewith, prior to the seventh (7th) Business Day after the Conversion Date
(assuming timely surrender of the Note and compliance with the other provisions
of this Note that relate to the conversion hereof), the Company shall pay to
such Payee, in cash, on a per diem basis, an amount equal to 0.2% of the
principal amount and all interest accrued thereon of the Note until such
delivery takes place and interest shall continue to accrue as provided in
Section 2 as if no Conversion Notice had been delivered.

          (iii) The Company's obligation to issue Common Stock upon conversion
of this Note shall be absolute, is independent of any covenant of any Payee, and
shall not be subject to: (i) any offset or defense; or (ii) any claims against
the holders of the Promissory Notes whether pursuant to this Note, the
Certificate of Incorporation of the Company, the Purchase Agreement, the
Investor Rights Agreement (as defined in the Purchase Agreement), the Warrants
(as defined in the Purchase Agreement) or otherwise.

          (iv) Subject to the provisions of Section 8(g), in the event that a
Conversion Triggering Event has occurred and the Company has given the Notice as
required by Section 8(b), this Note shall be converted in full on the Mandatory
Conversion Date as if the holder hereof had delivered a Conversion Notice with
respect to this Note on such date. Promptly thereafter, the holder of this Note
shall deliver this Note to the Company or its duly authorized transfer agent,
and upon receipt thereof, the Company shall issue or cause its transfer agent to
issue certificates evidencing the Common Stock into which this Note has been
converted.

          (v) Beneficial Ownership Cap. To the extent that (A) all of the
outstanding principal and interest due on this Note is not automatically
converted in full upon the occurrence of a Mandatory Conversion on account of
the application of Section 8(g), (B) a Notice has been duly delivered to the
Payee and the Maturity Date has occurred prior to the Mandatory Conversion Date
specified in such Notice or (C) the Payee elects to convert all of the
outstanding principal and interest due on this Note following a Prepayment
Notice and prior to Prepayment, but all of such amounts are not converted in
full on account of the application of Section 8(g) (each of the events referred
to in clauses (A), (B) and (C), a "Limited Conversion"), this Note shall remain
outstanding with respect to the amounts of unpaid principal and unpaid interest
remaining and such amounts remaining shall be deemed converted automatically
under this Section 8 at the first moment thereafter either when the Mandatory
Conversion Date occurs in the case of a Limited Conversion pursuant to clause
(B) above (except that such conversion shall remain subject to Section 8(g), and
if Section 8(g) applies, such conversion shall become a clause (A) Limited
Conversion following the Mandatory Conversion Date), or, in all other cases,


                                       8



when Section 8(g) would not prevent such conversion. Notwithstanding the
preceding sentence, upon the occurrence of the Limited Conversion, the rights of
the Payee pursuant to Sections 1, 2, 3, 4, 5, 6 and 7, including, without
limitation, the right to be repaid principal and interest in cash, shall be
terminated immediately and all other rights and obligations (including, without
limitation, the rights hereunder to adjustments to the Conversion Rate) shall
remain in full force and effect (the "Remaining Rights"); provided that, upon
the occurrence of a Sale Transaction, the resulting successor or acquiring
entity in such Sale Transaction (if not the Company) and, if an entity different
from the successor or acquiring entity, the entity whose capital stock or assets
the holders of the Common Stock are entitled to receive as a result of such Sale
Transaction, shall assume by written instrument all of the Remaining Rights (but
not the rights that have been terminated as provided above) under the Promissory
Notes and all of the rights and obligations of the Company under Transaction
Documents.

          (d) Fractional Shares. The Company shall not be required to issue a
fractional share of Common Stock upon conversion of this Note. As to any
fraction of a share which the holder of this Note would otherwise be entitled to
acquire upon such conversion, the Company shall pay an amount in cash equal to
the Current Market Price (as defined below) per share of Common Stock on the
date of conversion, multiplied by such fraction.

     "Current Market Price" means, in respect of any share of Common Stock on
any date herein specified:

               (1) if there shall not then be a public market for the Common
          Stock, the higher of (a) the book value per share of Common Stock at
          such date, and (b) the fair market value per share of Common Stock as
          determined in good faith by the Board, or

               (2) if there shall then be a public market for the Common Stock,
          the average of the daily market prices for the 20 consecutive trading
          days immediately before such date. The daily market price for each
          such trading day shall be (i) the closing bid price on such day on the
          principal stock exchange (including Nasdaq) on which such Common Stock
          is then listed or admitted to trading, or quoted, as applicable, (ii)
          if no sale takes place on such day on any such exchange, the last
          reported closing bid price on such day as officially quoted on any
          such exchange (including Nasdaq), (iii) if the Common Stock is not
          then listed or admitted to trading on any stock exchange, the last
          reported closing bid price on such day in the over-the-counter market,
          as furnished by the National Association of Securities Dealers
          Automatic Quotation System or the Pink Sheets LLC, (iv) if neither
          such corporation at the time is engaged in the business of reporting
          such prices, as furnished by any similar firm then engaged in such
          business, or (v) if there is no such firm, as furnished by any member
          of the National Association of Securities Dealers, Inc. (the "NASD")
          selected mutually by holders of a majority in interest of the
          Promissory Notes and the Company or, if they cannot agree upon such
          selection, as selected by two such members of the NASD, one of which
          shall be selected by holders of a majority in interest of the


                                       9



          Promissory Notes and one of which shall be selected by the Company (as
          applicable, the "Daily Market Price").

          (e) Stock Dividends, Subdivisions and Combinations. If at any time
while the this Note is outstanding, the Company shall:

               (i) cause the holders of its Common Stock to be entitled to
     receive a dividend payable in, or other distribution of, additional shares
     of Common Stock,

               (ii) subdivide its outstanding shares of Common Stock into a
     larger number of shares of Common Stock, or

               (iii) combine its outstanding shares of Common Stock into a
     smaller number of shares of Common Stock,

then in each such case the Conversion Rate shall be multiplied by a fraction of
which the numerator shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding immediately before such event and of which
the denominator shall be the number of shares of Common Stock outstanding
immediately after such event. Any adjustment made pursuant to clause (i) of this
Section 8(e) shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution,
and any adjustment pursuant to clauses (ii) or (iii) of this Section 8(e) shall
become effective immediately after the effective date of such subdivision or
combination. If any event requiring an adjustment under this paragraph occurs
during the period that a Conversion Rate is calculated hereunder, then the
calculation of such Conversion Rate shall be adjusted appropriately to reflect
such event.

          (f) Certain Other Distributions. If at any time while this Note is
outstanding the Company shall take a record of the holders of its Common Stock
for the purpose of entitling them to receive any dividend or other distribution
of:

               (i) cash,

               (ii) any evidences of its indebtedness, any shares of stock of
     any class or any other securities or property or assets of any nature
     whatsoever (other than cash or additional shares of Common Stock as
     provided in Section 8(e) hereof), or

               (iii) any warrants or other rights to subscribe for or purchase
     any evidences of its indebtedness, any shares of stock of any class or any
     other securities or property or assets of any nature whatsoever (in each
     case set forth in subparagraphs 8(f)(i), 8(f)(ii) and 8(f)(iii) hereof, the
     "Distributed Property"),

then upon any conversion of this Note that occurs after such record date, the
holder of this Note shall be entitled to receive, in addition to the Conversion
Shares, the Distributed Property that such holder would have been entitled to
receive in respect of such number of Conversion Shares had the holder been the
record holder of such Conversion Shares as of such record date. Such
distribution shall be made whenever any such conversion is made. In the event
that the


                                       10



Distributed Property consists of property other than cash, then the fair value
of such Distributed Property shall be as determined in good faith by the Board
and set forth in reasonable detail in a written valuation report (the "Valuation
Report") prepared by the Board. The Company shall give written notice of such
determination and a copy of the Valuation Report to the holder of this Note, and
if the holder objects to such determination within twenty (20) business days
following the date such notice is given, the Company shall submit such valuation
to an investment banking firm of recognized national standing selected by the
holder of this Note and acceptable to the Company in its reasonable discretion,
whose opinion shall be binding upon the Company and the holder of this Note. A
reclassification of the Common Stock (other than a change in par value, or from
par value to no par value or from no par value to par value) into shares of
Common Stock and shares of any other class of stock shall be deemed a
distribution by the Company to the holders of its Common Stock of such shares of
such other class of stock within the meaning of this Section 8(f) and, if the
outstanding shares of Common Stock shall be changed into a larger or smaller
number of shares of Common Stock as a part of such reclassification, such change
shall be deemed a subdivision or combination, as the case may be, of the
outstanding shares of Common Stock within the meaning of Section 8(e).

          (g) Blocking Provision.

               (i) Except as provided otherwise in this Section 8(g)(i), the
     number of Conversion Shares that may be acquired by any holder shall be
     limited to the extent necessary to insure that, following such conversion,
     the number of shares of Common Stock then beneficially owned by such holder
     and its Affiliates and any other persons or entities whose beneficial
     ownership of Common Stock would be aggregated with the holder's for
     purposes of Section 13(d) of the Exchange Act (including shares held by any
     "group" of which the holder is a member, but excluding shares beneficially
     owned by virtue of the ownership of securities or rights to acquire
     securities that have limitations on the right to convert, exercise or
     purchase similar to the limitation set forth herein) does not exceed 4.99%
     of the total number of shares of Common Stock of the Company then issued
     and outstanding (the "Beneficial Ownership Cap"). For purposes hereof,
     "group" has the meaning set forth in Section 13(d) of the Exchange Act and
     applicable regulations of the Securities and Exchange Commission, and the
     percentage held by the holder shall be determined in a manner consistent
     with the provisions of Section 13(d) of the Exchange Act. As used herein,
     the term "Affiliate" means any person or entity that, directly or
     indirectly through one or more intermediaries, controls or is controlled by
     or is under common control with a person or entity, as such terms are used
     in and construed under Rule 144 under the Securities Act. With respect to
     the holder of this Note, any investment fund or managed account that is
     managed on a discretionary basis by the same investment manager as such
     holder will be deemed to be an Affiliate of such holder. Each delivery of a
     Conversion Notice by the holder of this Note will constitute a
     representation by such holder that it has evaluated the limitation set
     forth in this paragraph and determined, subject to the accuracy of
     information filed under the Securities Act and the Exchange Act of 1934, as
     amended (the "Exchange Act") by the Company with respect to the outstanding
     Common Stock of the Company, that the issuance of the full number of shares
     of Common Stock requested in such Conversion Notice is permitted under this
     paragraph. This paragraph shall be construed and administered in such
     manner as shall be


                                       11



     consistent with the intent of the first sentence of this paragraph. Any
     provision hereof which would require a result that is not consistent with
     such intent shall be deemed severed herefrom and of no force or effect with
     respect to the conversion contemplated by a particular Conversion Notice.

               (ii) In the event the Company is prohibited from issuing shares
     of Common Stock as a result of any restrictions or prohibitions under
     applicable law or the rules or regulations of any stock exchange,
     interdealer quotation system or other self-regulatory organization, the
     Company shall as soon as possible seek the approval of its stockholders and
     take such other action to authorize the issuance of the full number of
     shares of Common Stock issuable upon the full conversion of the Promissory
     Notes.

               (iii) Notwithstanding the foregoing provisions of Section 8(g),
     any holder of Promissory Notes shall have the right prior to the time of
     the Closing (as defined in the Purchase Agreement) upon written notice to
     the Company, or after the time of the Closing upon (x) 61 days prior
     written notice to the Company or (y) upon a Sale Transaction, to choose not
     to be governed by the Beneficial Ownership Cap provided herein.

          (h) Common Stock Reserved. The Company shall at all times reserve and
keep available out of its authorized but unissued Common Stock, solely for
issuance upon the conversion of the Promissory Notes, such number of shares of
Common Stock as shall from time to time be issuable upon the conversion of all
the Promissory Notes at the time outstanding (without regard to any ownership
limitations provided in Section 8(g)).

          9. Other Provisions Applicable to Adjustments. The following
provisions shall be applicable to the making of adjustments of the number of
shares of Common Stock into which this Note is convertible and the current
Conversion Rate provided for in Section 8:

     (a) When Adjustments to Be Made. The adjustments required by Section 8
shall be made whenever and as often as any specified event requiring an
adjustment shall occur, except that any adjustment to the Conversion Rate that
would otherwise be required may be postponed (except in the case of a
subdivision or combination of shares of the Common Stock, as provided for in
Section 8(e)) up to, but not beyond the Conversion Date if such adjustment
either by itself or with other adjustments not previously made adds or subtracts
less than 1% of the shares of Common Stock into which this Note is convertible
immediately prior to the making of such adjustment. Any adjustment representing
a change of less than such minimum amount (except as aforesaid) which is
postponed shall be carried forward and made as soon as such adjustment, together
with other adjustments required by Section 8 and not previously made, would
result in a minimum adjustment or on the Conversion Date. For the purpose of any
adjustment, any specified event shall be deemed to have occurred at the close of
business on the date of its occurrence.

          (b) Fractional Interests. In computing adjustments under Section 8,
fractional interests in Common Stock shall be taken into account to the nearest
1/100th of a share.


                                       12



          (c) When Adjustment Not Required. If the Company undertakes a
transaction contemplated under Section 8(f) and as a result takes a record of
the holders of its Common Stock for the purpose of entitling them to receive a
dividend or distribution or subscription or purchase rights or other benefits
contemplated under Section 8(f) and shall, thereafter and before the
distribution to stockholders thereof, legally abandon its plan to pay or deliver
such dividend, distribution, subscription or purchase rights or other benefits
contemplated under Section 8(f), then thereafter no adjustment shall be required
by reason of the taking of such record and any such adjustment previously made
in respect thereof shall be rescinded and annulled.

          (d) Escrow of Stock. If after any property becomes distributable
pursuant to Section 8 by reason of the taking of any record of the holders of
Common Stock, but prior to the occurrence of the event for which such record is
taken, a holder of this Note converts the Note during such period or such holder
is unable to convert pursuant to Section 8(g), the holder of this Note shall
continue to be entitled to receive any shares of Common Stock issuable upon
conversion under Section 8 by reason of such adjustment (as if this Note were
not yet converted) and such shares or other property shall be held in escrow for
the holder of this Note by the Company to be issued to holder of this Note upon
and to the extent that the event actually takes place. Notwithstanding any other
provision to the contrary herein, if the event for which such record was taken
fails to occur or is rescinded, then such escrowed shares shall be canceled by
the Company and escrowed property returned to the Company.

          10. Replacement. Upon receipt of a duly executed, notarized and
unsecured written statement from the Payee with respect to the loss, theft or
destruction of this Note (or any replacement hereof), and, if requested by the
Company, an indemnity bond customary in the industry, or, in the case of a
mutilation of this Note, upon surrender and cancellation of such Note, the
Company shall issue a new Note, of like tenor and amount, in lieu of such lost,
stolen, destroyed or mutilated Note.

          11. Parties in Interest, Transferability. This Note shall be binding
upon the Company and its successors and permitted assigns and the terms hereof
shall inure to the benefit of the Payee and its successors and assigns. This
Note may be transferred or sold, subject to the provisions of Section 19 of this
Note, or pledged, hypothecated or otherwise granted as security by the Payee.

          12. Amendments. This Note may not be modified or amended in any manner
except in writing executed by the Company and the Payee.

          13. Notices. Any notice, demand, request, waiver or other
communication required or permitted to be given hereunder shall be in writing
and shall be effective (a) upon hand delivery by telecopy or facsimile at the
address or number designated below (if delivered on a business day during normal
business hours where such notice is to be received), or the first business day
following such delivery (if delivered other than on a business day during normal
business hours where such notice is to be received) or (b) on the second
business day following the date of mailing by express courier service, fully
prepaid, addressed to such address, or upon actual receipt of such mailing,
whichever shall first occur. The Company will give written notice to the Payee
at least twenty (20) days prior to the date on which dissolution, liquidation or


                                       13



winding-up will take place and in no event shall such notice be provided to the

provided herein, be subject to any other obligation of the Company (or the
performance thereof). The Company acknowledges that a breach by it of its
obligations hereunder will cause irreparable and material harm to the Payee and
that the remedy at law for any such breach may be inadequate. Therefore the
Company agrees that, in the event of any such breach or threatened breach, the
Payee shall be entitled, in addition to all other available rights and remedies,
at law or in equity, to such equitable relief, including but not limited to an
injunction restraining any such breach or threatened breach, without the
necessity of showing economic loss and without any bond or other security being
required.

          17. Failure or Indulgence Not Waiver. No failure or delay on the part
of the Payee in the exercise of any power, right or privilege hereunder shall

such power, right or privilege preclude other or further exercise thereof or of
any other right, power or privilege.

          18. Enforcement Expenses. The Company agrees to pay all costs and
expenses of enforcement of this Note, including, without limitation, reasonable
attorneys' fees and expenses.

shall not offer, sell or otherwise dispose of this Note other than in compliance
with the laws of the United States of America and as guided by the rules of the

Warrant as Exhibit A, duly executed by the Holder or its agent or attorney. Upon
receipt thereof, the Company shall, as promptly as practicable, and in any event
within three Business Days thereafter, execute or cause to be executed and

certificate or certificates representing Warrant Stock, deliver to the Holder a

Price, shall be fully paid and nonassessable and not subject to any preemptive

fractional share of Common Stock upon exercise of any Warrant. As to any

which are exercised in the same transaction, would otherwise be entitled to
purchase upon such exercise, the Company shall pay an amount in cash equal to
the Current Market Price per share of Common Stock on the date of exercise
multiplied by such fraction.

     2.3. Continued Validity. A Holder of shares of Common Stock issued upon the
exercise of this Warrant, in whole or in part (other than a Holder who acquires
such shares after the same have been publicly sold pursuant to a Registration
Statement under the Securities Act or sold pursuant to Rule 144 thereunder),
shall continue to be entitled with respect to such shares to all rights to which
it would have been entitled as the Holder under Sections 10 and 13 of this
Warrant.

     2.4. Restrictions on Exercise Amount.

     (i) Unless a Holder delivers to the Company irrevocable written notice
prior to the date of issuance hereof or sixty-one days prior to the effective
date of such notice that this Section 2.4(i) shall not apply to such Holder, the
Holder may not acquire a number of shares of Warrant Stock to the extent that,
upon such exercise, the number of shares of Common Stock then beneficially owned
by such holder and its Affiliates and any other persons or entities whose
beneficial ownership of Common Stock would be aggregated with the Holder's for
purposes of Section 13(d) of the Exchange Act (including shares held by any
"group" of which the holder is a member, but excluding shares beneficially owned
by virtue of the ownership of securities or rights to acquire securities that
have limitations on the right to convert, exercise or purchase similar to the
limitation set forth herein) exceeds 4.99% of the total number of shares of
Common Stock of the Company then issued and outstanding. For purposes hereof,
"group" has the meaning set forth in Section 13(d) of the Exchange Act and
applicable regulations of the Commission, and the percentage held by the holder
shall be determined in a manner consistent with the provisions of Section 13(d)
of the Exchange Act. Each delivery of a notice of exercise by a Holder will
constitute a representation by such Holder that it has evaluated the limitation
set forth in this paragraph and determined, based on the most recent public
filings by the Company with the Commission, that the issuance of the full number
of shares of Warrant Stock requested in such notice of exercise is permitted
under this paragraph.

     (ii) In the event the Company is prohibited from issuing shares of Warrant
Stock as a result of any restrictions or prohibitions under applicable law or
the rules or regulations of any


                                       5



stock exchange, interdealer quotation system or other self-regulatory
organization, the Company shall as soon as possible seek the approval of its
stockholders and take such other action to authorize the issuance of the full
number of shares of Common Stock issuable upon exercise of this Warrant.

     3. Transfer, Division and Combination.

     3.1. Transfer. The Warrants and the Warrant Stock shall be freely
transferable, subject to compliance with this Section 3.1 and all applicable
laws, including, but not limited to the Securities Act. If, at the time of the
surrender of this Warrant in connection with any transfer of this Warrant or the
resale of the Warrant Stock, this Warrant or the Warrant Stock, as applicable,
shall not be registered under the Securities Act, the Company may require, as a
condition of allowing such transfer (i) that the Holder or transferee of this
Warrant or the Warrant Stock as the case may be, furnish to the Company a
written opinion of counsel that is reasonably acceptable to the Company to the
effect that such transfer may be made without registration under the Securities
Act, (ii) that the Holder or transferee execute and deliver to the Company an
investment representation letter in form and substance acceptable to the Company
and substantially in the form attached as Exhibit C hereto and (iii) that the
transferee be an "accredited investor" as defined in Rule 501(a) promulgated
under the Securities Act. Transfer of this Warrant and all rights hereunder, in
whole or in part, in accordance with the foregoing provisions, shall be
registered on the books of the Company to be maintained for such purpose, upon
surrender of this Warrant at the principal office of the Company referred to in
Section 2.1 or the office or agency designated by the Company pursuant to
Section 12, together with a written assignment of this Warrant substantially in
the form of Exhibit B hereto duly executed by the Holder or its agent or
attorney and funds sufficient to pay any transfer taxes payable upon the making
of such transfer. Upon such surrender and, if required, such payment, the
Company shall execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees and in the denomination specified in such instrument of
assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be cancelled.
Following a transfer that complies with the requirements of this Section 3.1,
the Warrant may be exercised by a new Holder for the purchase of shares of
Common Stock regardless of whether the Company issued or registered a new
Warrant on the books of the Company.

     3.2. Restrictive Legends. Each certificate for Warrant Stock initially
issued upon the exercise of this Warrant, and each certificate for Warrant Stock
issued to any subsequent transferee of any such certificate, unless, in each
case, such Warrant Stock is eligible for resale without registration pursuant to
Rule 144(k) under the Exchange Act, shall bear the following legend:

"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 UNLESS, IN THE OPINION OF
COUNSEL REASONABLY SATISFACTORY TO THE COMPANY, SUCH REGISTRATION IS NOT
REQUIRED."


                                       6



          In addition, the legend set forth above shall be removed and the
Company shall issue a certificate without such legend to the holder of any
Warrant Stock upon which it is stamped, if, unless otherwise required by
applicable state securities laws, such Warrant Stock is registered for sale
under an effective registration statement filed under the Securities Act.

     3.3. Division and Combination; Expenses; Books. This Warrant may be divided
or combined with other Warrants upon presentation hereof at the aforesaid office
or agency of the Company, together with a written notice specifying the names
and denominations in which new Warrants are to be issued, signed by the Holder
or its agent or attorney. Subject to compliance with Section 3.1 as to any
transfer which may be involved in such division or combination, the Company
shall execute and deliver a new Warrant or Warrants in exchange for the Warrant
or Warrants to be divided or combined in accordance with such notice. The
Company shall prepare, issue and deliver at its own expense the new Warrant or
Warrants under this Section 3. The Company agrees to maintain, at its aforesaid
office or agency, books for the registration and the registration of transfer of
the Warrants.

     4. Adjustments. The number of shares of Common Stock for which this Warrant
is exercisable, and the price at which such shares may be purchased upon
exercise of this Warrant, shall be subject to adjustment from time to time as
set forth in this Section 4. The Company shall give the Holder notice of any
event described below which requires an adjustment pursuant to this Section 4 in
accordance with Sections 5.1 and 5.2.

     4.1. Stock Dividends, Subdivisions and Combinations. If at any time while
this Warrant is outstanding the Company shall:

          (i) declare a dividend or make a distribution on its outstanding
shares of Common Stock in shares of Common Stock,

          (ii) subdivide its outstanding shares of Common Stock into a larger
number of shares of Common Stock, or

          (iii) combine its outstanding shares of Common Stock into a smaller
number of shares of Common Stock, then:

     (1) the number of shares of Common Stock acquirable upon exercise of this
Warrant immediately after the occurrence of any such event shall be adjusted to
equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock that would have been acquirable under this
Warrant immediately prior to the record date for such dividend or distribution
or the effective date of such subdivision or combination would own or be
entitled to receive after such record date or the effective date of such
subdivision or combination, as applicable, and

     (2) the Current Warrant Price shall be adjusted to equal:

          (A) the Current Warrant Price in effect at the time of the record date
     for such dividend or distribution or of the effective date of such
     subdivision or combination, multiplied by the number of shares of Common
     Stock into which this Warrant is exercisable immediately prior to the
     adjustment, divided by


                                       7



          (B) the number of shares of Common Stock into which this Warrant is
     exercisable immediately after such adjustment.

     Any adjustment made pursuant to clause (i) of this paragraph shall become
effective immediately after the record date for the determination of
stockholders entitled to receive such dividend or distribution, and any
adjustment pursuant to clauses (ii) or (iii) of this paragraph shall become
effective immediately after the effective date of such subdivision or
combination.

     4.2. Other Provisions Applicable to Adjustments. The following provisions
shall be applicable to the making of adjustments of the number of shares of
Common Stock into which this Warrant is exercisable and the Current Warrant
Price provided for in Section 4:

          (a) When Adjustments to Be Made. The adjustments required by Section 4
shall be made whenever and as often as any specified event requiring an
adjustment shall occur, except that any that would otherwise be required may be
postponed (except in the case of a subdivision or combination of shares of the
Common Stock, as provided for in Section 4.1) up to, but not beyond the date of
exercise if such adjustment either by itself or with other adjustments not
previously made adds or subtracts less than 1% of the shares of Common Stock
into which this Warrant is exercisable immediately prior to the making of such
adjustment. Any adjustment representing a change of less than such minimum
amount (except as aforesaid) which is postponed shall be carried forward and
made as soon as such adjustment, together with other adjustments required by
this Section 4 and not previously made, would result in a minimum adjustment or
on the date of exercise. For the purpose of any adjustment, any specified event
shall be deemed to have occurred at the close of business on the date of its
occurrence.

          (b) Fractional Interests. In computing adjustments under this Section
4, fractional interests in Common Stock shall be taken into account to the
nearest 1/100th of a share.

          (c) When Adjustment Not Required. If the Company undertakes a
transaction contemplated under this Section 4 and as a result takes a record of
the holders of its Common Stock for the purpose of entitling them to receive a
dividend or distribution or subscription or purchase rights or other benefits
contemplated under this Section 4 and shall, thereafter and before the
distribution to stockholders thereof, legally abandon its plan to pay or deliver
such dividend, distribution, subscription or purchase rights or other benefits
contemplated under this Section 4, then thereafter no adjustment shall be
required by reason of the taking of such record and any such adjustment
previously made in respect thereof shall be rescinded and annulled.

          (d) Escrow of Stock. If after any property becomes distributable
pursuant to Section 4 by reason of the taking of any record of the holders of
Common Stock, but prior to the occurrence of the event for which such record is
taken, a holder of this Warrant exercises the Warrant during such time, then
such holder shall continue to be entitled to receive any shares of Common Stock
issuable upon exercise hereunder by reason of such adjustment and such shares or
other property shall be held in escrow for the holder of this Warrant by the
Company to be issued to holder of this Warrant upon and to the extent that the
event actually takes place. Notwithstanding any other provision to the contrary
herein, if the event for which such record was taken fails to occur or is
rescinded, then such escrowed shares shall be canceled by the Company and
escrowed property returned to the Company.


                                       8



     4.3. Reorganization, Reclassification, Merger, Consolidation or Disposition
of Assets.

          (a) If there shall occur a Change of Control and, pursuant to the
terms of such Change of Control, shares of common stock of the successor or
acquiring corporation, or any cash, shares of stock or other securities or
property of any nature whatsoever (including warrants or other subscription or
purchase rights) in addition to or in lieu of common stock of the successor or
acquiring corporation ("Other Property"), are to be received by or distributed
to the holders of Common Stock of the Company, then the Holder of this Warrant
shall have the right thereafter to receive, upon the exercise of the Warrant,
the number of shares of common stock of the successor or acquiring corporation
or of the Company, if it is the surviving corporation, and the Other Property
receivable upon or as a result of such Change of Control by a holder of the
number of shares of Common Stock into which this Warrant is exercisable
immediately prior to such event. The Company shall not effect any Change of
Control without the prior written consent of the holders of a majority in
interest of the Warrants (as defined in the Purchase Agreement) (in addition to
any other consent or voting rights with respect to such Change of Control that
such holders may have pursuant to this Warrant or applicable law) unless the
resulting successor or acquiring entity (if not the Company) and, if an entity
different from the successor or acquiring entity, the entity whose capital stock
or assets the holders of the Common Stock are entitled to receive as a result of
such Change of Control, assumes by written instrument all of the obligations of
this Warrant and the Transaction Documents (as defined in the Purchase
Agreement).

          (b) In case of any such Change of Control described in Section 4.3(a)
above, the resulting, successor or acquiring entity (if not the Company) and, if
an entity different from the successor or acquiring entity, the entity whose
capital stock or assets the holders of the Common Stock are entitled to receive
as a result of such Change of Control, shall assume by written instrument all of
the obligations of this Warrant and the Transaction Documents (as defined in the
Purchase Agreement), subject to such modifications as may be deemed appropriate
(as determined by resolution of the Board of Directors of the Company) in order
to provide for adjustments of shares of the Common Stock into which this Warrant
is exercisable which shall be as nearly equivalent as practicable to the
adjustments provided for in Section 4. For purposes of Section 4, common stock
of the successor or acquiring corporation shall include stock of such
corporation of any class which is not preferred as to dividends or assets on
liquidation over any other class of stock of such corporation and which is not
subject to redemption and shall also include any evidences of indebtedness,
shares of stock or other securities which are convertible into or exchangeable
for any such stock, either immediately or upon the arrival of a specified date
or the happening of a specified event and any warrants or other rights to
subscribe for or purchase any such stock. The foregoing provisions of this
Section 4 shall similarly apply to successive Change of Control transactions.

     4.4. Other Action Affecting Common Stock. In case at any time or from time
to time the Company shall take any action in respect of its Common Stock, other
than the payment of dividends permitted by Section 4 or any other action
described in Section 4, then, unless such action will not have a materially
adverse effect upon the rights of the holder of this Warrant, the number of
shares of Common Stock or other stock into which this Warrant is exercisable
and/or the purchase price thereof shall be adjusted in such manner as may be
equitable in the circumstances.


                                       9



     4.5. Certain Limitations. Notwithstanding anything herein to the contrary,
the Company agrees not to enter into any transaction which, by reason of any
adjustment hereunder, would cause the Current Warrant Price to be less than the
par value per share of Common Stock.

     4.6. Stock Transfer Taxes. The issue of stock certificates upon exercise of
this Warrant shall be made without charge to the holder for any tax in respect
of such issue. The Company shall not, however, be required to pay any tax which
may be payable in respect of any transfer involved in the issue and delivery of
shares in any name other than that of the holder of this Warrant, and the
Company shall not be required to issue or deliver any such stock certificate
unless and until the person or persons requesting the issue thereof shall have
paid to the Company the amount of such tax or shall have established to the
satisfaction of the Company that such tax has been paid.

     5. Notices to Warrant Holders.

     5.1. Certificate as to Adjustments. Upon the occurrence of each adjustment
or readjustment of the Current Warrant Price, the Company, at its expense, shall
promptly compute such adjustment or readjustment in accordance with the terms
hereof and prepare and furnish to the Holder of this Warrant a certificate
setting forth such adjustment or readjustment and showing in detail the facts
upon which such adjustment or readjustment is based. The Company shall, upon the
written request at any time of the Holder of this Warrant, furnish or cause to
be furnished to such Holder a like certificate setting forth (i) such
adjustments and readjustments, (ii) the Current Warrant Price at the time in
effect and (iii) the number of shares of Common Stock and the amount, if any, or
other property which at the time would be received upon the exercise of Warrants
owned by such Holder.

     5.2. Notice of Corporate Action. If at any time:

          (a) the Company shall take a record of the holders of its Common Stock
for the purpose of entitling them to receive a dividend (other than a cash
dividend payable out of earnings or earned surplus legally available for the
payment of dividends under the laws of the jurisdiction of incorporation of the
Company) or other distribution, or any right to subscribe for or purchase any
evidences of its indebtedness, any shares of stock of any class or any other
securities or property, or to receive any other right, or

          (b) there shall be any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company or any
consolidation or merger of the Company with, or any sale, transfer or other
disposition of all or substantially all the property, assets or business of the
Company to, another corporation, or

          (c) there shall be a voluntary or involuntary dissolution, liquidation
or winding up of the Company; or

          (d) the Company shall cause the holders of its Common Stock to be
entitled to receive (i) any dividend or other distribution of cash, (ii) any
evidences of its indebtedness, or (iii) any shares of stock of any class or any
other securities or property or assets of any nature whatsoever (other than cash
or additional shares of Common Stock as provided in Section 4.1 hereof and the
rights under the Company's Rights Agreement, dated as of October 31, 2001, by


                                       10



and between the Company and American Stock Transfer & Trust Company as Rights
Agent (the "Rights Agreement")); or (iv) any warrants or other rights to
subscribe for or purchase any evidences of its indebtedness, any shares of stock
of any class or any other securities or property or assets of any nature
whatsoever;

then, in any one or more of such cases, the Company shall give to the Holder (i)
at least 15 days' prior written notice of the date on which a record date shall
be selected for such dividend, distribution or right or for determining rights
to vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up, and (ii) in the case of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up, at least 15 days' prior written notice of the date when the same shall take
place. Such notice in accordance with the foregoing clause also shall specify
(i) the date on which any such record is to be taken for the purpose of such
dividend, distribution or right, the date on which the holders of Common Stock
shall be entitled to any such dividend, distribution or right, and the amount
and character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their shares of Common Stock for securities or other
property deliverable upon such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up. Each such written notice shall be sufficiently given if addressed to the
Holder at the last address of the Holder appearing on the books of the Company
and delivered in accordance with Section 15.2. Notwithstanding the forgoing
provisions of this Section 5.2, the Company shall give to the Holder at least
seven (7) Business Days prior written notice of the occurrence of any
Distribution Date (as defined in the Rights Agreement).

     5.3. No Rights as Stockholder. This Warrant does not entitle the Holder to
any voting or other rights as a stockholder of the Company prior to exercise and
payment for the Warrant Price in accordance with the terms hereof.

     6. No Impairment. The Company shall not by any action, including, without
limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of the Holder against impairment. Without limiting the generality of the
foregoing, the Company will (a) not increase the par value of any shares of
Common Stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise immediately prior to such increase in par
value, (b) take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant, and (c) use its best efforts to
obtain all such authorizations, exemptions or consents from any public
regulatory body having jurisdiction thereof as may be necessary to enable the
Company to perform its obligations under this Warrant. Upon the request of the
Holder, the Company will at any time during the period this Warrant is
outstanding acknowledge in writing, in form satisfactory to the Holder, the
continuing validity of this Warrant and the obligations of the Company
hereunder.


                                       11



     7. Reservation and Authorization of Common Stock; Registration With
Approval of Any Governmental Authority. From and after the Closing Date, the
Company shall at all times reserve and keep available for issue upon the
exercise of Warrants such number of its authorized but unissued shares of Common
Stock as will be sufficient to permit the exercise in full of all outstanding
Warrants (without regard to any ownership limitations provided in Section
2.4(i)). All shares of Common Stock which shall be so issuable, when issued upon
exercise of any Warrant and payment therefor in accordance with the terms of
such Warrant, shall be duly and validly issued and fully paid and nonassessable,
and not subject to preemptive rights. Before taking any action which would cause
an adjustment reducing the Current Warrant Price below the then par value, if
any, of the shares of Common Stock issuable upon exercise of the Warrants, the
Company shall take any corporate action which may be necessary in order that the
Company may validly and legally issue fully paid and non-assessable shares of
such Common Stock at such adjusted Current Warrant Price. Before taking any
action which would result in an adjustment in the number of shares of Common
Stock for which this Warrant is exercisable or in the Current Warrant Price, the
Company shall obtain all such authorizations or exemptions thereof, or consents
thereto, as may be necessary from any public regulatory body or bodies having
jurisdiction thereof. If any shares of Common Stock required to be reserved for
issuance upon exercise of Warrants require registration or qualification with
any governmental authority under any federal or state law before such shares may
be so issued (other than as a result of a prior or contemplated distribution by
the Holder of this Warrant), the Company will in good faith and as expeditiously
as possible and at its expense endeavor to cause such shares to be duly
registered.

     8. Taking of Record; Stock and Warrant Transfer Books. In the case of all
dividends or other distributions by the Company to the holders of its Common
Stock with respect to which any provision of Section 4 refers to the taking of a
record of such holders, the Company will in each such case take such a record
and will take such record as of the close of business on a Business Day. The
Company will not at any time, except upon dissolution, liquidation or winding up
of the Company, close its stock transfer books or Warrant transfer books so as
to result in preventing or delaying the exercise or transfer of any Warrant.

     9. Registration Rights. The resale of the Warrant Stock shall be registered
in accordance with the terms and conditions contained in that certain Investor
Rights Agreement dated of even date hereof, among the Holder, the Company and
the other parties named therein (the "Investor Rights Agreement"). The Holder
acknowledges that pursuant to the Investor Rights Agreement, the Company has the
right to request that the Holder furnish information regarding such Holder and
the distribution of the Warrant Stock as is required by law or the Commission to
be disclosed in the Registration Statement (as such term is defined in the
Investor Rights Agreement), and the Company may exclude from such registration
the shares of Warrant Stock acquirable hereunder if Holder fails to furnish such
information within a reasonable time prior to the filing of each Registration
Statement, supplemented prospectus included therein and/or amended Registration
Statement.

     10. Supplying Information. Upon any default by the Company of its
obligations hereunder or under the Investor Rights Agreement, the Company shall
cooperate with the Holder in supplying such information as may be reasonably
necessary for such Holder to complete and file any information reporting forms
presently or hereafter required by the Commission as a


                                       12



condition to the availability of an exemption from the Securities Act for the
sale of any Warrant or Restricted Common Stock.

     11. Loss or Mutilation. Upon receipt by the Company from the Holder of
evidence reasonably satisfactory to it of the ownership of and the loss, theft,
destruction or mutilation of this Warrant and indemnity or security reasonably
satisfactory to it and reimbursement to the Company of all reasonable expenses
incidental thereto and in case of mutilation upon surrender and cancellation
hereof, the Company will execute and deliver in lieu hereof a new Warrant of
like tenor to the Holder; provided, however, that in the case of mutilation, no
indemnity shall be required if this Warrant in identifiable form is surrendered
to the Company for cancellation.

     12. Office of the Company. As long as any of the Warrants remain
outstanding, the Company shall maintain an office or agency (which may be the
principal executive offices of the Company) where the Warrants may be presented
for exercise, registration of transfer, division or combination as provided in
this Warrant.

     13. Financial and Business Information.

     13.1. Quarterly Information. The Company will deliver to the Holder, as
soon as available and in any event within 45 days after the end of each of the
first three quarters of each fiscal year of the Company, one copy of an
unaudited consolidated balance sheet of the Company and its subsidiaries as at
the end of such quarter, and the related unaudited consolidated statements of
income, retained earnings and cash flow of the Company and its subsidiaries for
such quarter and, in the case of the second and third quarters, for the portion
of the fiscal year ending with such quarter, setting forth in each case in
comparative form the figures for the corresponding periods in the previous
fiscal year. Such financial statements shall be prepared by the Company in
accordance with GAAP (except as may be indicated thereon or in the notes
thereto) and accompanied by the certification of the Company's chief executive
officer or chief financial officer that such financial statements present fairly
the consolidated financial position, results of operations and cash flow of the
Company and its subsidiaries as at the end of such quarter and for such
year-to-date period, as the case may be; provided, however, that the Company
shall have no obligation to deliver such quarterly information under this
Section 13.1 to the extent it is publicly available; and provided further, that
if such information contains material non-public information, the Company shall
so notify the Holder prior to delivery thereof and the Holder shall have the
right to refuse delivery of such information.

     13.2. Annual Information. The Company will deliver to the Holder as soon as
available and in any event within 90 days after the end of each fiscal year of
the Company, one copy of an audited consolidated balance sheet of the Company
and its subsidiaries as at the end of such year, and audited consolidated
statements of income, retained earnings and cash flow of the Company and its
subsidiaries for such year; setting forth in each case in comparative form the
figures for the corresponding periods in the previous fiscal year; all prepared
in accordance with GAAP, and which audited financial statements shall be
accompanied by an opinion thereon of the independent certified public
accountants regularly retained by the Company, or any other firm of independent
certified public accountants of recognized national standing selected by the
Company; provided, however, that the Company shall have no obligation to deliver
such annual information under this Section 13.2 to the extent it is publicly
available; and provided further,


                                       13



that if such information contains material non-public information, the Company
shall so notify the Holder prior to delivery thereof and the Holder shall have
the right to refuse delivery of such information.

     13.3. Filings. The Company will file on or before the required date all
regular or periodic reports (pursuant to the Exchange Act) with the Commission
and will deliver to Holder promptly upon their becoming available one copy of
each report, notice or proxy statement sent by the Company to its stockholders
generally.

     14. Limitation of Liability. No provision hereof, in the absence of
affirmative action by the Holder to purchase shares of Common Stock, and no
enumeration herein of the rights or privileges of the Holder hereof, shall give
rise to any liability of the Holder for the purchase price of any Common Stock,
whether such liability is asserted by the Company or by creditors of the
Company.

     15. Miscellaneous.

     15.1. Nonwaiver and Expenses. No course of dealing or any delay or failure
to exercise any right hereunder on the part of the Holder shall operate as a
waiver of such right or otherwise prejudice the Holder's rights, powers or
remedies. If the Company fails to make, when due, any payments provided for
hereunder, or fails to comply with any other material provision of this Warrant,
the Company shall pay to the Holder such amounts as shall be sufficient to cover
any third party costs and expenses including, but not limited to, reasonable
attorneys' fees, including those of appellate proceedings, incurred by the
Holder in collecting any amounts due pursuant hereto or in otherwise enforcing
any of its rights, powers or remedies hereunder.

     15.2. Notice Generally. All notices, requests, demands or other
communications provided for herein shall be in writing and shall be given in the
manner and to the addresses set forth in the Purchase Agreement.

     15.3. Successors and Assigns. Subject to compliance with the provisions of
Section 3.1, this Warrant and the rights evidenced hereby shall inure to the

     3. Registration Procedures.

     In connection with the Company's registration obligations hereunder, the

Company on another form appropriate for such registration in accordance
herewith) (which shall include a Plan of Distribution substantially in the form
of Exhibit A attached hereto), and cause the Registration Statement to become
effective and remain effective as provided herein; provided, however, that not
less than three (3) Business Days prior to the filing of the Registration
Statement or any related Prospectus or any amendment or supplement thereto, the
Company shall (i) furnish to the Special Counsel, copies of all such documents
proposed to be filed, which documents (other than those incorporated by
reference) will be subject to the review of such Special Counsel, and (ii) at
the request of any Holder cause its officers and directors, counsel and
independent certified public accountants to respond to such inquiries as shall
be necessary, in the reasonable opinion of counsel to such Holders, to conduct a
reasonable investigation within the meaning of the Securities Act. The Company
shall not file the Registration Statement or any such Prospectus or any
amendments or supplements thereto to which the Holders of a majority of the
Registrable Securities or the Special Counsel shall reasonably object within
three (3) Business Days after their receipt


                                       4



thereof. In the event of any such objection, the Holders shall provide the
Company with any requested revisions to such prospectus or supplement within two
(2) Business Days after such objection.

     (b) (i) Prepare and file with the Commission such amendments, including
post-effective amendments, to the Registration Statement as may be necessary to
keep the Registration Statement continuously effective as to the applicable
Registrable Securities for the Effectiveness Period and to the extent any
Registrable Securities are not included in such Registration Statement for
reasons other than the failure of the Holder to comply with Section 3(m) hereof,
shall prepare and file with the Commission such amendments to the Registration
Statement or such additional Registration Statements in order to register for
resale under the Securities Act all Registrable Securities; (ii) cause the
related Prospectus to be amended or supplemented by any required Prospectus
supplement, and as so supplemented or amended to be filed pursuant to Rule 424
(or any similar provisions then in force) promulgated under the Securities Act;
(iii) respond as promptly as reasonably practicable, and in no event later than
ten (10) Business Days to any comments received from the Commission with respect
to the Registration Statement or any amendment thereto and as promptly as
reasonably practicable provide the Holders true and complete copies of all
correspondence from and to the Commission relating to the Registration
Statement, but not, without the prior written consent of the Holders, any
comments that would result in the disclosure to the Holders of material and
non-public information concerning the Company; and (iv) comply in all material
respects with the provisions of the Securities Act and the Exchange Act with
respect to the disposition of all Registrable Securities covered by the
Registration Statement during the applicable period in accordance with the
intended methods of disposition by the Holders thereof set forth in the
Registration Statement as so amended or in such Prospectus as so supplemented.

     (c) Notify Holders of Registrable Securities to be sold and the Special
Counsel as promptly as reasonably practicable (A) when a Prospectus or any
Prospectus supplement or post-effective amendment to the Registration Statement
is proposed to be filed (but in no event in the case of this subparagraph (A),
less than three (3) Business Days prior to date of such filing); (B) when the
Commission notifies the Company whether there will be a "review" of such
Registration Statement and whenever the Commission comments in writing on such
Registration Statement; and (C) with respect to the Registration Statement or
any post-effective amendment, when the same has become effective, and after the
effectiveness thereof: (i) of any request by the Commission or any other Federal
or state governmental authority for amendments or supplements to the
Registration Statement or Prospectus or for additional information; (ii) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement covering any or all of the Registrable Securities or the
initiation of any Proceedings for that purpose; (iii) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (iv) if the financial statements included in the Registration
Statement become ineligible for inclusion therein or of the occurrence of any
event that makes any statement made in the Registration Statement or Prospectus
or any document incorporated or deemed to be incorporated therein by reference
untrue in any material respect or that requires any revisions to the
Registration


                                       5



Statement, Prospectus or other documents so that, in the case of the
Registration Statement or the Prospectus, as the case may be, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.
Without limitation to any remedies to which the Holders may be entitled under
this Agreement, if any of the events described in Section 3(c)(C)(i),
3(c)(C)(ii), 3(c)(C)(iii) or 3(c)(C)(iv) occur, the Company shall use its
reasonable best efforts to respond to and correct the event.

     (d) Use its reasonable best efforts to avoid the issuance of, or, if
issued, use reasonable best efforts to obtain the withdrawal of, (i) any order
suspending the effectiveness of the Registration Statement or (ii) any
suspension of the qualification (or exemption from qualification) of any of the
Registrable Securities for sale in any jurisdiction, at the earliest practicable
time.

     (e) If requested by any Holder of Registrable Securities, (i) promptly
incorporate in a Prospectus supplement or post-effective amendment to the
Registration Statement such information as the Company reasonably agrees should
be included therein and (ii) make all required filings of such Prospectus
supplement or such post-effective amendment as soon as reasonably practicable
after the Company has received notification of the matters to be incorporated in
such Prospectus supplement or post-effective amendment.

     (f) Furnish to each Holder and the Special Counsel, without charge, at
least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, and all exhibits to the
extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

     (g) Promptly deliver to each Holder and the Special Counsel, without
charge, as many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

     (h) Prior to any public offering of Registrable Securities, use its
reasonable best efforts to register or qualify or cooperate with the selling
Holders and the Special Counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions within the United States as any Holder requests in
writing, to keep each such registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all other
acts or things necessary or advisable to enable the disposition in such
jurisdictions of the Registrable Securities covered by a Registration Statement;
provided, however, that the Company shall not be required to qualify generally
to do business in any jurisdiction where it is not then so qualified or to take
any action that would subject it to general service of process in any
jurisdiction where it is


                                       6



not then so subject or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

     (i) Cooperate with the Holders to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold pursuant
to a Registration Statement, which certificates shall be free, to the extent
permitted by applicable law and the Purchase Agreement, of all restrictive
legends, and to enable such Registrable Securities to be in such denominations
and registered in such names as any Holder may request at least two (2) Business
Days prior to any sale of Registrable Securities. In connection therewith, the
Company shall promptly after the effectiveness of the Registration Statement
cause an opinion of counsel to be delivered to and maintained with its transfer
agent, together with any other authorizations, certificates and directions
required by the transfer agent, which authorize and direct the transfer agent to
issue such Registrable Securities without legend upon sale by the Holder of such
shares of Registrable Securities under the Registration Statement.

     (j) Following the occurrence of any event contemplated by Section
3(c)(C)(iv), as promptly as possible, prepare a supplement or amendment,
including a post-effective amendment, to the Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to
be incorporated therein by reference, and file any other required document so
that, as thereafter delivered, neither the Registration Statement nor such
Prospectus will contain an untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

     (k) Cause all Registrable Securities relating to such Registration
Statement to be listed on any United States securities exchange, quotation
system, market or over-the-counter bulletin board on which similar securities
issued by the Company are then listed.

     (l) Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders earnings statements satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than 45 days after the end of any 3-month
period (or 90 days after the end of any 12-month period if such period is a
fiscal year) commencing on the first day of the first fiscal quarter of the
Company after the effective date of the Registration Statement, which statement
shall conform to the requirements of Rule 158.

     (m) Request each selling Holder to furnish to the Company information
regarding such Holder and the distribution of such Registrable Securities as is
required by law or the Commission to be disclosed in the Registration Statement,
and the Company may exclude from such registration the Registrable Securities of
any such Holder who fails to furnish such information within a reasonable time
prior to the filing of each Registration Statement, supplemented Prospectus
and/or amended Registration Statement.

     If the Registration Statement refers to any Holder by name or otherwise as
the holder of any securities of the Company, then such Holder shall have the
right to require (if such reference to such Holder by name or otherwise is not
required by the Securities Act or any


                                       7



similar federal statute then in force) the deletion of the reference to such
Holder in any amendment or supplement to the Registration Statement filed or
prepared subsequent to the time that such reference ceases to be required.

     Each Holder agrees by its acquisition of such Registrable Securities that,
upon receipt of a notice from the Company of the occurrence of any event of the
kind described in Section 3(c)(C)(i), 3(c)(C)(ii), 3(c)(C)(iii), 3(c)(C)(iv), or
3(n), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(j), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

     (n) If (i) there is material non-public information regarding the Company
which the Company's Board of Directors (the "Board") reasonably determines not
to be in the Company's best interest to disclose and which the Company is not
otherwise required to disclose, or (ii) there is a significant business
opportunity (including, but not limited to, the acquisition or disposition of
assets (other than in the ordinary course of business) or any merger,
consolidation, tender offer or other similar transaction) available to the
Company which the Board reasonably determines not to be in the Company's best
interest to disclose and which the Company would be required to disclose under
the Registration Statement, then the Company may (i) postpone or suspend filing
or effectiveness of a registration statement or (ii) notify the Holders that the
Registration Statement may not be used in connection with any sales of the
Company's securities, in each case, for a period not to exceed 30 consecutive
days, provided that the Company may not postpone or suspend its obligation under
this Section 3(n) for more than 60 days in the aggregate during any 12 month
period (each, a "Blackout Period").

     4. Registration Expenses.

     All fees and expenses incident to the performance of or compliance with
this Agreement by the Company shall be borne by the Company whether or not the
Registration Statement is filed or becomes effective and whether or not any
Registrable Securities are sold pursuant to the Registration Statement. The fees
and expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses (A) with respect to filings required to be made with each
securities exchange, quotation system, market or over-the-counter bulletin board
on which Registrable Securities are required hereunder to be listed, (B) with
respect to filings required to be made with the Commission, and (C) in
compliance with state securities or Blue Sky laws (including, without
limitation, reasonable and documented fees and disbursements of Special Counsel
in connection with Blue Sky qualifications of the Registrable Securities and
determination of the eligibility of the Registrable Securities for investment
under the laws of such jurisdictions as the Holders of a majority of Registrable
Securities may designate)), (ii) printing expenses (including, without
limitation, expenses of printing certificates for Registrable Securities and of
printing or photocopying prospectuses),


                                       8



(iii) messenger, telephone and delivery expenses, (iv) Securities Act liability
insurance, if the Company so desires such insurance, (v) fees and expenses of
all other Persons retained by the Company in connection with the consummation of
the transactions contemplated by this Agreement, including, without limitation,
the Company's independent public accountants (including, in the case of an
underwritten offering, the expenses of any comfort letters or costs associated
with the delivery by independent public accountants of a comfort letter or
comfort letters) and legal counsel, and (vi) reasonable and documented fees and
expenses of the Special Counsel in connection with any Registration Statement
hereunder. In addition, the Company shall be responsible for all of its internal
expenses incurred in connection with the consummation of the transactions
contemplated by this Agreement (including, without limitation, all salaries and
expenses of its officers and employees performing legal or accounting duties),
the expense of any annual audit, the fees and expenses incurred in connection
with the listing of the Registrable Securities on any securities exchange as
required hereunder.

     5. Indemnification.

     (a) Indemnification by the Company. The Company shall, notwithstanding any
termination of this Agreement, indemnify and hold harmless each Holder, the
officers, directors, agents, brokers (including brokers who offer and sell
Registrable Securities as principal as a result of a pledge or any failure to
perform under a margin call of Common Stock), investment advisors and employees
of each of them, each Person who controls any such Holder (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the
officers, directors, agents and employees of each such controlling Person, to
the fullest extent permitted by applicable law, from and against any and all
losses, claims, damages, liabilities, costs (including, without limitation,
costs of preparation and reasonable attorneys' fees) and expenses (collectively,
"Losses"), as incurred, arising out of or relating to any untrue or alleged
untrue statement of a material fact contained or incorporated by reference in
the Registration Statement, any Prospectus or any form of prospectus or in any
amendment or supplement thereto or in any preliminary prospectus, or arising out
of or relating to any omission or alleged omission of a material fact required
to be stated therein or necessary to make the statements therein (in the case of
any Prospectus or form of prospectus or amendment or supplement thereto, in the
light of the circumstances under which they were made) not misleading, except to
the extent, but only to the extent, that (i) such untrue statements or omissions
are based solely upon information regarding such Holder furnished in writing to
the Company by such Holder expressly for use therein, which information was
reasonably relied on by the Company for use therein or to the extent that such
information relates to (x) such Holder and was reviewed and expressly approved
in writing by such Holder expressly for use in the Registration Statement, such
Prospectus or such form of prospectus or in any amendment or supplement thereto
or (y) such Holder's proposed method of distribution of Registrable Securities
as set forth in Exhibit A (or as such Holder otherwise informs the Company in
writing); or (ii) in the case of an occurrence of an event of the type described
in Section 3(c)(C)(ii), 3(c)(C)(iii), 3(c)(C)(iv) or 3(n), the use by a Holder
of an outdated or defective Prospectus after the delivery to the Holder of
written notice from the Company that the Prospectus is outdated or defective and
prior to the receipt by such Holder of the Advice contemplated in Section 3(m);
provided, however, that the indemnity agreement contained in this Section 5(a)
shall not apply to amounts paid in


                                       9



settlement of any Losses if such settlement is effected without the prior
written consent of the Company, which consent shall not be unreasonably
withheld. The Company shall notify the Holders promptly of the institution,
threat or assertion of any Proceeding of which the Company is aware in
connection with the transactions contemplated by this Agreement. Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on behalf of an Indemnified Party (as defined in Section 5(c) to this Agreement)
and shall survive the transfer of the Registrable Securities by the Holders.

     (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents and employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses, as
incurred, arising solely out of or based solely upon any untrue statement of a
material fact contained in the Registration Statement, any Prospectus, or any
form of prospectus, or in any amendment or supplement thereto, or arising solely
out of or based solely upon any omission of a material fact required to be
stated therein or necessary to make the statements therein (in the case of any
Prospectus or form of prospectus or supplement thereto, in the light of the
circumstances under which they were made) not misleading, to the extent, but
only to the extent, that (i) such untrue statement or omission is contained in
or omitted from any information so furnished in writing by such Holder to the
Company specifically for inclusion in the Registration Statement or such
Prospectus and that such information was reasonably relied upon by the Company
for use in the Registration Statement, such Prospectus, or in any amendment or
supplement thereto, or to the extent that such information relates to (x) such
Holder and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus, or such form
of prospectus or in any amendment or supplement thereto or (y) such Holder's
proposed method of distribution of Registrable Securities as set forth in
Exhibit A (or as such Holder otherwise informs the Company in writing), (ii) in
the case of an occurrence of an event of the type described in Section
3(c)(C)(ii), 3(c)(C)(iii), 3(c)(C)(iv) or 3(n), the use by a Holder of an
outdated or defective Prospectus after the delivery to the Holder of written
notice from the Company that the Prospectus is outdated or defective and prior
to the receipt by such Holder of the Advice contemplated in Section 3(m) or
(iii) such Holder's failure to comply with the Prospectus delivery requirements
of the Securities Act through no fault of the Company; provided, however, that
the indemnity agreement contained in this Section 5(b) shall not apply to
amounts paid in settlement of any Losses if such settlement is effected without
the prior written consent of the Holder, which consent shall not be unreasonably
withheld. Notwithstanding anything to the contrary contained herein, the Holder
shall be liable under this Section 5(b) for only that amount as does not exceed
the net proceeds to such Holder as a result of the sale of Registrable
Securities pursuant to such Registration Statement.

     (c) Conduct of Indemnification Proceedings. If any Proceeding shall be
brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall have the right to assume the defense thereof, including
the employment of counsel reasonably satisfactory to


                                       10



the Indemnified Party and the payment of all reasonable fees and expenses
incurred in connection with defense thereof; provided, that the failure of any
Indemnified Party to give such notice shall not relieve the Indemnifying Party
of its obligations or liabilities pursuant to this Agreement, except (and only)
to the extent that it shall be finally determined by a court of competent
jurisdiction (which determination is not subject to appeal or further review)
that such failure shall have proximately and materially adversely prejudiced the
Indemnifying Party.

     An Indemnified Party shall have the right to employ separate counsel in any
such Proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or
Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised in writing by counsel that a conflict of interest is
likely to exist if the same counsel were to represent such Indemnified Party and
the Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the reasonable
expense of the Indemnifying Party). The Indemnifying Party shall not be liable
for any settlement of any such Proceeding effected without its written consent,
which consent shall not be unreasonably withheld. No Indemnifying Party shall,
without the prior written consent of the Indemnified Party, effect any
settlement of any pending Proceeding in respect of which any Indemnified Party
is a party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability on claims that are the subject matter of
such Proceeding and does not impose any monetary or other obligation or
restriction on the Indemnified Party.

     All reasonable fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within ten (10) Business Days of written notice thereof to the
Indemnifying Party, which notice shall be delivered no more frequently than on a
monthly basis (regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided, that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder).

     (d) Contribution. If a claim for indemnification under Section 5(a) or 5(b)
is unavailable to an Indemnified Party because of a failure or refusal of a
governmental authority to enforce such indemnification in accordance with its
terms (by reason of public policy or otherwise), then each 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


                                       11



the Indemnifying Party and Indemnified Party in connection with the actions,
statements or omissions that resulted in such Losses as well as any other
relevant equitable considerations. The relative fault 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 of a material fact, has been
taken or 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, statement or
omission. The amount paid or payable by a party as a result of any Losses shall
be deemed to include, subject to the limitations set forth in Section 5(c), any
reasonable attorneys' or other reasonable fees or expenses incurred by such
party in connection with any Proceeding to the extent such party would have been
indemnified for such fees or expenses if the indemnification provided for in
this Section was available to such party in accordance with its terms.
Notwithstanding anything to the contrary contained herein, the Holder shall be
required to contribute under this Section 5(d) for only that amount as does not
exceed the net proceeds to such Holder as a result of the sale of Registrable
Securities pursuant to such Registration Statement.

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

     The indemnity and contribution agreements contained in this Section are in
addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties. The indemnity and contribution agreements herein are in
addition to and not in diminution or limitation of any indemnification
provisions under the Purchase Agreement.

     6. Rule 144.

     As long as any Holder owns Notes, Conversion Shares, Warrants or Warrant
Shares, 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 after the date hereof pursuant to Section 13(a) or 15(d) of
the Exchange Act. As long as any Holder owns Notes, Conversion Shares, Warrants
or Warrant Shares, if the Company is not required to file reports pursuant to
Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the
Holders and make publicly available in accordance with Rule 144(c) promulgated
under the Securities Act annual and quarterly financial statements, together
with a discussion and analysis of such financial statements in form and
substance substantially similar to those that would otherwise be required to be
included in reports required by Section 13(a) or 15(d) of the Exchange Act, as
well as any other information required thereby, in the time period that such
filings would have been required to have been made under the Exchange Act. The
Company further covenants that it will take such further action as any Holder
may reasonably request, all to the extent required from time to time to enable
such Person to sell Notes, Conversion Shares, Warrants and Warrant Shares
without registration under the Securities Act within the limitation of the
exemptions provided by


                                       12



Rule 144 promulgated under the Securities Act, including compliance with the
provisions of the Purchase Agreement relating to the transfer of the Notes,
Conversion Shares, Warrants and Warrant Shares. Upon the request of any Holder,
the Company shall deliver to such Holder a written certification of a duly
authorized officer as to whether it has complied with such requirements.

     7. Miscellaneous.

     (a) Remedies. In the event of a breach by the Company or by a Holder, of
any of their obligations under this Agreement, each Holder or the Company, as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not provide adequate compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

     (b) No Inconsistent Agreements. Except as otherwise disclosed in the
Purchase Agreement, neither the Company nor any of its subsidiaries is a party
to an agreement currently in effect, nor shall the Company or any of its
subsidiaries, on or after the date of this Agreement, enter into any agreement
with respect to its securities that is inconsistent with the rights granted to
the Holders in this Agreement or otherwise conflicts with the provisions hereof.
Without limiting the generality of the foregoing, other than with respect to the
rights of the holders of the Company's currently outstanding convertible notes
and the common stock underlying such convertible notes and shares of common
stock issued under the Standby Equity Distribution Agreement with Cornell
Capital and its affiliates and shares of common stock issued to Cornell Capital
and its affiliates in connection with such transaction, without the written
consent of the Holders of a majority of the then outstanding Registrable
Securities, the Company shall not grant to any Person the right to request the
Company to register any securities of the Company under the Securities Act
unless the rights so granted are subject in all respects to the rights of the
Holders set forth herein, and are not otherwise in conflict with the provisions
of this Agreement.

     (c) Notice of Effectiveness. Within two (2) Business Days after the
Registration Statement which includes the Registrable Securities is ordered
effective by the Commission, the Company shall deliver, and shall cause legal
counsel for the Company to deliver, to the transfer agent for such Registrable
Securities (with copies to the Holders whose Registrable Securities are included
in such Registration Statement) confirmation that the Registration Statement has
been declared effective by the Commission in the form attached hereto as Exhibit
B.

     (d) Piggy-Back Registrations. If at any time when there is not an effective
Registration Statement covering all of the Registrable Securities, the Company
shall determine to prepare and file with the Commission a registration statement
relating to an offering for its own account or the account of others under the
Securities Act of any of its equity securities, other than on Form S-4 or Form
S-8 (each as promulgated under the


                                       13



Securities Act) or their then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee
benefit plans and other than with respect to the rights of the holders of the
Company's currently outstanding warrants and convertible notes and the common
stock underlying such warrants and convertible notes and the Company's currently
effective registration statement on Form S-1 relating to its Standby Equity
Distribution Agreement with Cornell Capital, as it may be amended from time to
time, the Company shall send to each Holder of Registrable Securities written
notice of such determination and, if within seven (7) Business Days after
receipt of such notice, any such Holder shall so request in writing (which
request shall specify the Registrable Securities intended to be disposed of by
the Holder), the Company will cause the registration under the Securities Act of
all Registrable Securities which the Company has been so requested to register
by the Holder, to the extent required to permit the disposition of the
Registrable Securities so to be registered, provided that if at any time after
giving written notice of its intention to register any securities and prior to
the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register or to
delay registration of such securities, the Company may, at its election, give
written notice of such determination to such Holder and, thereupon, (i) in the
case of a determination not to register, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration (but
not from its obligation to pay expenses in accordance with Section 4 hereof),
and (ii) in the case of a determination to delay registering, shall be permitted
to delay registering any Registrable Securities being registered pursuant to
this Section 7(d) for the same period as the delay in registering such other
securities. The Company shall include in such registration statement all or any
part of such Registrable Securities such Holder requests to be registered. In
the case of an underwritten public offering, if the managing underwriter(s) or
underwriter(s) should reasonably object to the inclusion of the Registrable
Securities in such registration statement, then if the Company after
consultation with the managing underwriter should reasonably determine that the
inclusion of such Registrable Securities, would materially adversely affect the
offering contemplated in such registration statement, and based on such
determination recommends inclusion in such registration statement of fewer or
none of the Registrable Securities of the Holders, then (x) the number of
Registrable Securities of the Holders included in such registration statement
shall be reduced pro-rata among such Holders (based upon the number of
Registrable Securities requested to be included in the registration), if the
Company after consultation with the underwriter(s) recommends the inclusion of
fewer Registrable Securities, or (y) none of the Registrable Securities of the
Holders shall be included in such registration statement, if the Company after
consultation with the underwriter(s) recommends the inclusion of none of such
Registrable Securities; provided, however, that if securities are being offered
for the account of other persons or entities as well as the Company, such
reduction shall not represent a greater fraction of the number of Registrable
Securities intended to be offered by the Holders than the fraction of similar
reductions imposed on such other persons or entities (other than the Company).

     (e) Failure to File Registration Statement and Other Events. The Company
and the Holders agree that the Holders will suffer damages if the Registration
Statement is not filed on or prior to the Filing Date and maintained in the
manner contemplated herein during the Effectiveness Period. The Company and the
Holders further agree that it would not be


                                       14



feasible to ascertain the extent of such damages with precision. Accordingly, if
(i) the Registration Statement is not filed on or prior to the Filing Date, or
(ii) the Company fails to file with the Commission a request for acceleration in
accordance with Rule 461 promulgated under the Securities Act within five (5)
Business Days of the date that the Company is notified (orally or in writing,
whichever is earlier) by the Commission that a Registration Statement will not
be "reviewed," or not subject to further review, or (iii) the Registration
Statement is filed with and declared effective by the Commission but thereafter
ceases to be effective as to all Registrable Securities at any time prior to the
expiration of the Effectiveness Period, without being succeeded immediately by a
subsequent Registration Statement filed with the Commission, except as otherwise
permitted by this Agreement, including pursuant to Section 3(n), or (iv) trading
in the Common Stock shall be suspended or if the Common Stock is delisted from
each securities exchange, quotation system, market or over-the-counter bulletin
board on which Registrable Securities are required hereunder to be listed (each
an "Exchange"), without immediately being listed on any other Exchange, for any
reason for more than five (5) Business Days, other than pursuant to Section
3(n), or (v) the Company refuses or fails to effect any conversion of the Notes
into Conversion Shares or any exercise of Warrants into Warrant Shares in
accordance with the terms of the Notes and Warrants for any reason without the
consent of the particular Holder (any such failure or breach being referred to
as an "Event"), the Company shall pay in cash as liquidated damages for such
failure and not as a penalty to each Holder an amount equal to two percent (2%)
of such Holder's Subscription Amount for the initial thirty (30) day period
until the applicable Event has been cured, which shall be pro rated for such
periods less than thirty (30) days and two percent (2%) of such Holder's
Subscription Amount for each subsequent thirty (30) day period until the
applicable Event has been cured which shall be pro rated for such periods less
than thirty days (the "Periodic Amount"). Payments to be made pursuant to this
Section 7(e) shall be due and payable immediately upon demand in immediately
available cash funds. The parties agree that the Periodic Amount represents a
reasonable estimate on the part of the parties, as of the date of this
Agreement, of the amount of damages that may be incurred by the Holders if the
Registration Statement is not filed on or prior to the Filing Date and
maintained in the manner contemplated herein during the Effectiveness Period or
if any other Event as described herein has occurred. Notwithstanding the
foregoing, the Company shall remain obligated to cure the breach or correct the
condition that caused the Event, and the Holder shall have the right to take any
action necessary or desirable to enforce such obligation. Each Holder of
Registrable Securities acknowledges that, notwithstanding any provision of this
Agreement, no damages shall be payable in connection with the Company's
imposition of a Blackout Period in accordance with Section 3(n) of this
Agreement.

     (f) Specific Enforcement, Consent to Jurisdiction.

          (i) The Company and the Holders acknowledge and agree that irreparable
     damage would occur in the event that any of the provisions of this
     Agreement were not performed in accordance with their specific terms or
     were otherwise breached. It is accordingly agreed that the parties shall be
     entitled to an injunction or injunctions to prevent or cure breaches of the
     provisions of this Agreement and to enforce specifically the terms and
     provisions hereof, this being in addition to any other remedy to which any
     of them may be entitled by law or equity.


                                       15



          (ii) Each of the Company and the Holders (i) hereby irrevocably
     submits to the exclusive jurisdiction of the state and federal courts
     located in New York City, New York for the purposes of any suit, action or
     proceeding arising out of or relating to this Agreement and (ii) hereby
     waives, and agrees not to assert in any such suit, action or proceeding,
     any claim that it is not personally subject to the jurisdiction of such
     court, that the suit, action or proceeding is brought in an inconvenient
     forum or that the venue of the suit, action or proceeding is improper. Each
     of the Company and the Holders consents to process being served in any such
     suit, action or proceeding by mailing a copy thereof to such party at the
     address in effect for notices to it under this Agreement and agrees that
     such service shall constitute good and sufficient service of process and
     notice thereof. Nothing in this Section 7(f) shall affect or limit any
     right to serve process in any other manner permitted by law.

     (g) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given,
unless the same shall be in writing and signed by the Company and the Holders of
at least a majority of the Registrable Securities. Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect
to a matter that relates exclusively to the rights of Holders and that does not
directly or indirectly affect the rights of other Holders may be given by
Holders of the Registrable Securities to which such waiver or consent relates;
provided, however, that the provisions of this sentence may not be amended,
modified, or supplemented except in accordance with the provisions of the
immediately preceding sentence.

     (h) Notices. Any and all notices or other communications or deliveries
required or permitted to be provided hereunder shall be in writing and shall be
deemed given and effective on the earlier of (i) the date of transmission, if
such notice or communication is delivered via facsimile at the facsimile
telephone number specified for notice prior to 5:00 p.m., New York City time, on
a Business Day, (ii) the next Business Day after the date of transmission, if
such notice or communication is delivered via facsimile at the facsimile number
specified in this Section on a day that is not a Business Day or later than 5:00
p.m., New York City time, on any date and earlier than 11:59 p.m., New York City
time, on such date, (iii) the Business Day following the date of mailing, if
sent by nationally recognized overnight courier service such as Federal Express
or (iv) actual receipt by the party to whom such notice is required to be given.
The addresses for such communications shall be with respect to each Holder at
its address set forth under its name on Schedule 1 attached hereto, or with
respect to the Company, addressed to:

          Access Pharmaceuticals, Inc.
          2600 Stemmons Freeway, Suite 176

party may most recently have designated in writing to the other parties hereto
by such notice. Copies of notices to the Company shall be sent to:

                                       17



signature is delivered by electronic means or facsimile transmission, such
signature shall create a valid binding obligation of the party executing (or on
whose behalf such signature is executed) the same with the same force and effect
as if such facsimile signature were the original thereof.

     (l) Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York, without regard to principles
of conflicts of law thereof.

     (m) Cumulative Remedies. The remedies provided herein are cumulative and
not exclusive of any remedies provided by law.

     (n) Severability. If any term, provision, covenant or restriction of this

void or unenforceable in any respect, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their reasonable efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and
declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.

     (o) Headings. The headings herein are for convenience only, do not
constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof.

     (p) Obligations of Purchasers. The Company acknowledges that the
obligations of each Purchaser under this Agreement, are several and not joint
with the obligations of any other Purchaser, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser under this Agreement. The decision of each Purchaser to enter into to
this Agreement has been made by such Purchaser independently of any other
Purchaser. The Company further acknowledges that nothing contained in this
Agreement, and no action taken by any Purchaser pursuant hereto, shall be deemed
to constitute the Purchasers as a partnership, an association, a joint venture
or any other kind of entity, or create a presumption that the Purchasers are in
any way acting in concert or as a group with respect to such obligations or the
transactions contemplated hereby. Each Purchaser shall be entitled to
independently protect and enforce its rights, including without limitation, the
rights arising out of this Agreement, and it shall not be necessary for any
other Purchaser to be joined as an additional party in any proceeding for such
purpose.

     Each Purchaser was introduced to the Company by SCO Securities LLC which
has acted solely as agent for the Company and not for any Purchaser (other than
itself). Each Purchaser has been represented by its own separate legal counsel
in their review and negotiation of this Agreement and with respect to the
transactions contemplated hereby. For reasons of administrative convenience
only, this Agreement has been prepared by Special Counsel (counsel for SCO
Securities LLC) and the Special Counsel will perform certain


                                       18



duties under this Agreement. Such counsel does not represent all of the
Purchasers but only SCO Securities LLC. The Company has elected to provide all
Purchasers with the same terms and Agreement for the convenience of the Company
and not because it was required or requested to do so by the Purchasers. The
Company acknowledges that such procedure with respect to this Agreement in no
way creates a presumption that the Purchasers are in any way acting in concert
or as a group with respect to this Agreement or the transactions contemplated
hereby or thereby.

                              PLAN OF DISTRIBUTION

     We are registering the shares of common stock on behalf of the selling
security holders. Sales of shares may be made by selling security holders,
including their respective donees, transferees, pledgees or other
successors-in-interest directly to purchasers or to or through underwriters,
broker-dealers or through agents. Sales may be made from time to time on the
________________, any other exchange or market upon which our shares may trade
in the future, in the over-the-counter market or otherwise, at market prices
prevailing at the time of sale, at prices related to market prices, or at
negotiated or fixed prices. The shares may be sold by one or more of, or a
combination of, the following:

o    a block trade in which the broker-dealer so engaged will attempt to sell
     the shares as agent but may position and resell a portion of the block as
     principal to facilitate the transaction (including crosses in which the
     same broker acts as agent for both sides of the transaction);

o    purchases by a broker-dealer as principal and resale by such broker-dealer,
     including resales for its account, pursuant to this prospectus;

o    ordinary brokerage transactions and transactions in which the broker
     solicits purchases;

o    through options, swaps or derivatives;

o    in privately negotiated transactions;

o    in making short sales or in transactions to cover short sales; and

o    put or call option transactions relating to the shares.

     The selling security holders may effect these transactions by selling
shares directly to purchasers or to or through broker-dealers, which may act as
agents or principals. These broker-dealers may receive compensation in the form
of discounts, concessions or commissions from the selling security holders
and/or the purchasers of shares for whom such broker-dealers may act as agents
or to whom they sell as principals, or both (which compensation as to a
particular broker-dealer might be in excess of customary commissions). The
selling security holders have advised us that they have not entered into any
agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of their securities.

     The selling security holders may enter into hedging transactions with
broker-dealers or other financial institutions. In connection with those
transactions, the broker-dealers or other financial institutions may engage in
short sales of the shares or of securities convertible into or exchangeable for
the shares in the course of hedging positions they assume with the selling
security holders. The selling security holders may also enter into options or
other


                                       24



transactions with broker-dealers or other financial institutions which require
the delivery of shares offered by this prospectus to those broker-dealers or
other financial institutions. The broker-dealer or other financial institution
may then resell the shares pursuant to this prospectus (as amended or
supplemented, if required by applicable law, to reflect those transactions).

     The selling security holders and any broker-dealers that act in connection
with the sale of shares may be deemed to be "underwriters" within the meaning of
Section 2(11) of the Securities Act of 1933, and any commissions received by
broker-dealers or any profit on the resale of the shares sold by them while
acting as principals may be deemed to be underwriting discounts or commissions
under the Securities Act. The selling security holders may agree to indemnify
any agent, dealer or broker-dealer that participates in transactions involving
sales of the shares against liabilities, including liabilities arising under the
Securities Act. We have agreed to indemnify each of the selling security holders
and each selling security holder has agreed, severally and not jointly, to
indemnify us against some liabilities in connection with the offering of the
shares, including liabilities arising under the Securities Act.

     The selling security holders will be subject to the prospectus delivery
requirements of the Securities Act. We have informed the selling security
holders that the anti-manipulative provisions of Regulation M promulgated under
the Securities Exchange Act of 1934 may apply to their sales in the market.

     Selling security holders also may resell all or a portion of the shares in
open market transactions in reliance upon Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of Rule 144.

     Upon being notified by a selling security holder that a material
arrangement has been entered into with a broker-dealer for the sale of shares
through a block trade, special offering, exchange distribution or secondary
distribution or a purchase by a broker or dealer, we will file a supplement to
this prospectus, if required pursuant to Rule 424(b) under the Securities Act,
disclosing:

o    the name of each such selling security holder and of the participating
     broker-dealer(s);

o    the number of shares involved;

o    the initial price at which the shares were sold;

o    the commissions paid or discounts or concessions allowed to the
     broker-dealer(s), where applicable;

o    that such broker-dealer(s) did not conduct any investigation to verify the
     information set out or incorporated by reference in this prospectus; and

o    other facts material to the transactions.


                                       25



     In addition, if required under applicable law or the rules or regulations
of the Commission, we will file a supplement to this prospectus when a selling
security holder notifies us that a donee or pledgee intends to sell more than
500 shares of common stock.

     We are paying all expenses and fees customarily paid by the issuer in
connection with the registration of the shares. The selling security holders
will bear all brokerage or underwriting discounts or commissions paid to
broker-dealers in connection with the sale of the shares.

            FORM OF NOTICE OF EFFECTIVENESS OF REGISTRATION STATEMENT

[Name and Address of Transfer Agent]

Re: Access Pharmaceuticals, Inc.

Dear [______]:

     We are counsel to Access Pharmaceuticals, Inc., a Delaware corporation (the
"Company"), and have represented the Company in connection with that certain
Convertible Note and Warrant Purchase Agreement (the "Purchase Agreement") dated
as of __________________, 2006 by and among the Company and the buyers named
therein (collectively, the "Holders") pursuant to which the Company issued to
the Holders its secured convertible promissory notes (the "Notes") convertible
into shares of its Common Stock, par value $0.01 per share (the "Common Stock"),
and warrants to purchase shares of the Common Stock (the "Warrants"). Pursuant
to the Purchase Agreement, the Company has also entered into an Investor Rights
Agreement with the Holders (the "Investor Rights Agreement") pursuant to which
the Company agreed, among other things, to register the shares of Common Stock
issuable upon conversion of the Notes, in payment of interest on the Notes and
upon exercise of the Warrants, under the Securities Act of 1933, as amended (the
"1933 Act"). In connection with the Company's obligations under the Investor
Rights Agreement, on ____________ ___, 2006, the Company filed a Registration
Statement on Form S-__ (File No. 333-_____________) (the "Registration
Statement") with the Securities and Exchange Commission (the "SEC") relating to
the Registrable Securities which names each of the Holders as a selling
securityholder thereunder.

     In connection with the foregoing, we advise you that a member of the SEC's
staff has advised us by telephone that the SEC has entered an order declaring
the Registration Statement effective under the 1933 Act at [ENTER TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

Very truly yours,
