         1. DEFINITIONS. As used in this Agreement, the following terms shall

Holders.

         "QUALIFIED PUBLIC OFFERING" shall mean a firm commitment underwritten
public offering pursuant to an effective registration statement under the
Securities Act covering the Company's Common Stock.

         The terms "REGISTER", "REGISTERED", and "REGISTRATION" refer to a
registration effected by preparing and filing a registration statement on Form
S-1, S-2, S-3, SB-1 or SB-2 in compliance with the Securities Act of 1933, as
amended ("REGISTRATION STATEMENT"), and the declaration or ordering of the
effectiveness of such Registration Statement.

         "REGISTRABLE SECURITIES" shall mean all Common Stock not previously
sold to the public and issued upon conversion of the Notes purchased by or
issued to the Holders, including Common Stock issued pursuant to stock splits,
stock dividends and similar distributions.


                                        1

         "REGISTRATION EXPENSES" shall mean all expenses incurred by the Company
in complying with this Agreement, including, without limitation, all federal and
state registration, qualification, and filing fees, printing expenses, fees and
disbursements of counsel for the Company and one special counsel for all Holders
(if different from counsel to the Company), fees and disbursements of
independent public accountants for the Company, fees and expenses (including
counsel fees) incurred in connection with complying with state securities or
"blue sky" laws, fees of the National Association of Securities Dealers, Inc.,
transfer taxes, fees of transfer agents and registrars, and the expense of any
special audits incident to or required by any such registration.

         "SECURITIES ACT" shall mean the Securities Act of 1933, as amended, or
any similar federal statute, and the rules and regulations of the Commission
thereunder, all as the same shall be in effect at the time.

         "SELLING EXPENSES" shall mean all underwriting discounts and selling
commissions applicable to the sale of Registrable Securities pursuant to this
Agreement.

         2. NOTICE OF PIGGYBACK REGISTRATION AND INCLUSION OF REGISTRABLE
SECURITIES. Subject to the terms of this Agreement, if after the closing of the
Company's initial Qualified Public Offering the Company decides to Register any
of its Common Stock (either for its own account or the account of a security
holder or holders exercising their respective demand registration rights) on a
form that would be suitable for a registration involving solely Registrable
Securities, the Company will: (i) promptly give each Holder written notice
thereof (which shall include a list of the jurisdictions in which the Company
intends to attempt to qualify such securities under the applicable Blue Sky or
other state securities laws) and (ii) include in such Registration (and any
related qualification under Blue Sky laws or other compliance), and in any
underwriting involved therein, all the Registrable Securities specified in a
written request delivered to the Company by any Holder within 20 days after
delivery of such written notice from the Company.

         3. UNDERWRITING IN PIGGYBACK REGISTRATION.

         (A) NOTICE OF UNDERWRITING IN PIGGYBACK REGISTRATION. If the
Registration of which the Company gives notice is for a Registered public
offering involving an underwriting, the Company shall so advise the Holders as a
part of the written notice given pursuant to Section 2. In such event, the right
of any Holder to Registration shall be conditioned upon such underwriting and
the inclusion of such Holder's Registrable Securities in such underwriting to
the extent provided in this Agreement. All Holders proposing to distribute their
securities through such underwriting shall (together with the Company and the
other holders distributing their securities through such underwriting) enter
into an underwriting agreement with the underwriter's representative for such
offering (the "Underwriter's Representative"). The Holders shall have no right
to participate in the selection of the underwriters for an offering pursuant to
this Agreement.

         (B) MARKETING LIMITATION IN PIGGYBACK REGISTRATION. If the
Underwriter's Representative advises the Holders seeking registration of
Registrable Securities pursuant to this Agreement in writing that market factors
(including, without limitation, the aggregate number of shares of Common Stock
requested to be Registered, the general condition of the market, and the status
of the persons proposing to sell securities pursuant to the Registration)
require a limitation of the number of shares to be underwritten, the number of
shares that may be included in the Registration and underwriting by selling
shareholders shall be allocated among all Holders requesting and legally
entitled to include such securities in such Registration, in proportion, as
nearly as practicable, to the respective amounts of Registrable Securities which
such Holders would otherwise be entitled to include in such Registration. No
Registrable Securities or other securities excluded from the underwriting by
reason of this Section 3(b) shall be included in the Registration Statement.


                                       2
<PAGE>

         4. WITHDRAWAL IN PIGGYBACK REGISTRATION. If any Holder disapproves of
the terms of any such underwriting, such person may elect to withdraw therefrom
by written notice to the Company and the Underwriter's Representative delivered
at least seven days prior to the effective date of the Registration Statement.
Any Registrable Securities or other securities excluded or withdrawn from such
underwriting shall be withdrawn from such Registration.

         5. EXPENSES OF REGISTRATION. All Registration Expenses incurred in
connection with Registrations pursuant to this Agreement, shall be borne by the
Company. All Registration Expenses incurred in connection with any other
Registration, qualification, or compliance, shall be apportioned among the
Holders and other holders of the securities so registered on the basis of the
number of shares so registered. All Selling Expenses shall be borne by the
holders of the securities Registered pro rata on the basis of the number of
shares Registered.

         6. TERMINATION OF REGISTRATION RIGHTS. The rights to cause the Company
to register securities granted under this Agreement and to receive notices
pursuant to Section 2 of this Agreement shall terminate, with respect to each
Holder, on the earlier of (i) the date five years after the closing date of the
first Qualified Public Offering of securities pursuant to a Registration
Statement to occur after the date of this Agreement, and (ii) with respect to
each Holder if such Holder is eligible to sell all of such Holder's Registrable
Securities under Rule 144 of the Securities Act within any three month period
without volume limitations, or under Rule 144(k) thereunder.

         7. REGISTRATION PROCEDURES AND OBLIGATIONS. Whenever required under
this Agreement to effect the registration of any Registrable Securities, the
Company shall, as expeditiously as reasonably possible:

         (a) Prepare and file with the Commission a Registration Statement with
respect to such Registrable Securities and use its reasonable efforts to cause
such Registration Statement to become effective, and, upon the request of the
Holders of a majority of the Registrable Securities registered thereunder, keep
such Registration Statement effective for up to 120 days.

         (b) Prepare and file as expeditiously as reasonably practicable and in
any event within ninety (90) days with the Commission such amendments and
supplements to such Registration Statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such Registration Statement.

         (c) Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the

<PAGE>

         (d) Use its reasonable efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business in any jurisdiction where it is not
so qualified or to file a general consent to service of process in any such
states or jurisdictions, and provided further that in the event any jurisdiction
in which the securities shall be qualified imposes a non-waivable requirement
that expenses incurred in connection with the qualification of the securities be
borne by selling shareholders, such expenses shall be payable pro rata by
selling shareholders.

         (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering. Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

         (f) Notify each Holder of Registrable Securities covered by such
Registration Statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

         (g) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant to such Registration Statement and a CUSIP number
for all such Registrable Securities, in each case not later than the effective
date of such registration.

         (h) Furnish, at the request of any Holder requesting registration of
Registrable Securities pursuant to this Agreement, on the date that such
Registrable Securities are delivered for sale in connection with a registration
pursuant to this Agreement, (i) an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters (with a copy provided to each
holder of Registrable Securities) in an underwritten public offering, and (ii) a
letter dated such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering, addressed
to the underwriters (with a copy provided to each holder of Registrable
Securities).

         (i) Use all reasonable efforts to list the Registrable Securities
covered by such registration statement on any securities exchange on which the
Common Stock of the Company is then listed, or such securities exchange as shall
be selected by the Company.

         (j) Notify each seller of Registrable Securities under such
registration statement of (i) the effectiveness of such registration statement,
(ii) the filing of any post-effective amendments to such registration statement,
or (iii) the filing of a supplement to such registration statement.

         (k) Make available for inspection upon reasonable notice during the
Company's regular business hours by each seller of Registrable Securities, any
underwriter participating in any distribution pursuant to such registration
statement, and any attorney, accountant or other agent retained by such seller
or underwriter, all material financial and other records, pertinent corporate
documents and properties of the Company, and cause the Company's officers,
directors and employees to supply all information reasonably requested by any
such seller, underwriter, attorney, accountant or agent in connection with such
registration statement.

         8. INFORMATION FURNISHED BY HOLDER.

         (a) It shall be a condition precedent of the Company's obligations
under this Agreement that each Holder of Registrable Securities included in any
Registration furnish to the Company such information regarding such Holder and
the distribution proposed by such Holder or Holders as the Company may
reasonably request in writing and as shall be required in connection with any
Registration.

         (b) Any Holder that makes an untrue statement or omission will
indemnify and hold harmless the Company, each of its officers, directors,
employees and agents, legal counsel, independent accountant, underwriter against
all Damages, claims, liability, judgments, attorneys fees, court costs or other
harm of any nature whatsoever arising out of or based upon any untrue statement
or omission contained in any such Registration Statement or any document
required for, or related to, a Registration. Company shall notify any Holder
against which it may seek indemnification of any such claim related to any
untrue statement or omission by any Holder. The indemnifying party shall have
the right to participate in and to assume the defense of such claim; provided,
that the indemnifying party must reasonably approve defense counsel selected by
the indemnifying, however, if either party reasonably determines that there may
be a conflict between the position of the Company and the Holders in conducting
the defense of such action, suit, or proceeding by reason of recognized claims
for indemnity, then counsel for such party shall be entitled to conduct the
defense to the extent reasonably determined by such counsel to be necessary to
protect the interest of such party. If damages are adjudged to be attributable
to more than one party, the amount paid or payable as damages shall be prorated
as is appropriate to reflect the relative fault of each party that contributed
to cause the damage. The obligations of the Company and Holders under this
Section shall survive the completion of any offering of Registrable Securities
in a registration statement under this Agreement or otherwise.


         9. GOVERNING LAW. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Nevada. Any suit for the enforcement
of this Agreement may be brought in the courts of Texas or any federal court
sitting in Texas and each party hereto consents to the non-exclusive
jurisdiction of each such court and to service of process in any such suit being
made upon the Company by mail at the address specified above. Each party hereto
hereby waives any objection that it may now or hereafter have to the venue of
any such suit or any such court or that such suit was brought in any
inconvenient court.

         10. COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         11. HEADINGS. The headings of the sections of this Agreement are for
convenience and shall not by themselves determine the interpretation of this
Agreement.
