                           (c) The failure by the Company to observe or perform
any of its obligations hereunder or in the Security Agreement for ten (10) days
after receipt by the Company of notice of such failure from the Secured Party;
and

                                       7
<PAGE>

                           (d) Any breach of, or default under, the Warrants.

                  5. Duty To Hold In Trust. Upon the occurrence of any Event of
Default and at any time thereafter, the Company shall, upon receipt by it of any
revenue, income or other sums subject to the Security Interest, whether payable
pursuant to the Notes or otherwise, or of any check, draft, note, trade
acceptance or other instrument evidencing an obligation to pay any such sum,
hold the same in trust for the Secured Party and shall forthwith endorse and
transfer any such sums or instruments, or both, to the Secured Party for
application to the satisfaction of the Obligations.

                  6. Rights and Remedies Upon Default. Upon occurrence of any
Event of Default and at any time thereafter, the Secured Party shall have the
right to exercise all of the remedies conferred hereunder and under the Notes,
and the Secured Party shall have all the rights and remedies of a secured party
under the UCC and/or any other applicable law (including the Uniform Commercial
Code of any jurisdiction in which any Intellectual Property is then located).
Without limitation, the Secured Party shall have the following rights and
powers:

                           (a) The Secured Party shall have the right to take
possession of the Intellectual Property and, for that purpose, enter, with the
aid and assistance of any person, any premises where the Intellectual Property,
or any part thereof, is or may be placed and remove the same, and the Company
shall assemble the Intellectual Property and make it available to the Secured
Party at places which the Secured Party shall reasonably select, whether at the
Company's premises or elsewhere, and make available to the Secured Party,
without rent, all of the Company's respective premises and facilities for the
purpose of the Secured Party taking possession of, removing or putting the
Intellectual Property in saleable or disposable form.

                           (b) The Secured Party shall have the right to operate
the business of the Company using the Intellectual Property and shall have the
right to assign, sell, lease or otherwise dispose of and deliver all or any part
of the Intellectual Property, at public or private sale or otherwise, either
with or without special conditions or stipulations, for cash or on credit or for
future delivery, in such parcel or parcels and at such time or times and at such
place or places, and upon such terms and conditions as the Secured Party may
deem commercially reasonable, all without (except as shall be required by
applicable statute and cannot be waived) advertisement or demand upon or notice
to the Company or right of redemption of the Company, which are hereby expressly
waived. Upon each such sale, lease, assignment or other transfer of Intellectual
Property, the Secured Party may, unless prohibited by applicable law which
cannot be waived, purchase all or any part of the Intellectual Property being
sold, free from and discharged of all trusts, claims, right of redemption and
equities of the Company, which are hereby waived and released.

                  7. Applications of Proceeds. The proceeds of any such sale,
lease or other disposition of the Intellectual Property hereunder shall be
applied first, to the expenses of retaking, holding, storing, processing and
preparing for sale, selling, and the like (including, without limitation, any
taxes, fees and other costs incurred in connection therewith) of the
Intellectual Property, to the reasonable attorneys' fees and expenses incurred
by the Secured Party in enforcing its rights hereunder and in connection with
collecting, storing and disposing of the Intellectual Property, and then to
satisfaction of the Obligations, and to the payment of any other amounts
required by applicable law, after which the Secured Party shall pay to the
Company any surplus proceeds. If, upon the sale, license or other disposition of
the Intellectual Property, the proceeds thereof are insufficient to pay all
amounts to which the Secured Party is legally entitled, the Company will be
liable for the deficiency, together with interest thereon, at the rate of 15%
per annum (the "Default Rate"), and the reasonable fees of any attorneys
employed by the Secured Party to collect such deficiency. To the extent
permitted by applicable law, the Company waives all claims, damages and demands
against the Secured Party arising out of the repossession, removal, retention or
sale of the Intellectual Property, unless due to the gross negligence or willful
misconduct of the Secured Party.

                                       8
<PAGE>

                  8. Costs and Expenses. The Company agrees to pay all
out-of-pocket fees, costs and expenses incurred in connection with any filing
required hereunder, including without limitation, any financing statements,
continuation statements, partial releases and/or termination statements related
thereto or any expenses of any searches reasonably required by the Secured
Party. The Company shall also pay all other claims and charges which in the
reasonable opinion of the Secured Party might prejudice, imperil or otherwise
affect the Intellectual Property or the Security Interest therein. The Company
will also, upon demand, pay to the Secured Party the amount of any and all
reasonable expenses, including the reasonable fees and expenses of its counsel
and of any experts and agents, which the Secured Party may incur in connection
with (i) the enforcement of this Agreement, (ii) the custody or preservation of,
or the sale of, collection from, or other realization upon, any of the
Intellectual Property, or (iii) the exercise or enforcement of any of the rights
of the Secured Party under the Notes. Until so paid, any fees payable hereunder
shall be added to the principal amount of the Notes and shall bear interest at
the Default Rate.

                  9. Responsibility for Intellectual Property. The Company
assumes all liabilities and responsibility in connection with all Intellectual
Property, and the obligations of the Company hereunder or under the Notes and
the Warrants shall in no way be affected or diminished by reason of the loss,
destruction, damage or theft of any of the Intellectual Property or its
unavailability for any reason.

                  10. Security Interest Absolute. All rights of the Secured
Party and all Obligations of the Company hereunder, shall be absolute and
unconditional, irrespective of: (a) any lack of validity or enforceability of
this Agreement, the Notes, the Warrants or any agreement entered into in
connection with the foregoing, or any portion hereof or thereof; (b) any change
in the time, manner or place of payment or performance of, or in any other term
of, all or any of the Obligations, or any other amendment or waiver of or any
consent to any departure from the Notes, the Warrants or any other agreement
entered into in connection with the foregoing; (c) any exchange, release or
nonperfection of any of the Intellectual Property, or any release or amendment
or waiver of or consent to departure from any other Intellectual Property for,
or any guaranty, or any other security, for all or any of the Obligations; (d)
any action by the Secured Party to obtain, adjust, settle and cancel in its sole
discretion any insurance claims or matters made or arising in connection with
the Intellectual Property; or (e) any other circumstance which might otherwise
constitute any legal or equitable defense available to the Company, or a
discharge of all or any part of the Security Interest granted hereby. Until the
Obligations shall have been paid and performed in full, the rights of the
Secured Party shall continue even if the Obligations are barred for any reason,
including, without limitation, the running of the statute of limitations or
bankruptcy. The Company expressly waives presentment, protest, notice of
protest, demand, notice of nonpayment and demand for performance. In the event
that at any time any transfer of any Intellectual Property or any payment
received by the Secured Party hereunder shall be deemed by final order of a
court of competent jurisdiction to have been a voidable preference or fraudulent
conveyance under the bankruptcy or insolvency laws of the United States, or
shall be deemed to be otherwise due to any party other than the Secured Party,
then, in any such event, the Company's obligations hereunder shall survive
cancellation of this Agreement, and shall not be discharged or satisfied by any
prior payment thereof and/or cancellation of this Agreement, but shall remain a
valid and binding obligation enforceable in accordance with the terms and
provisions hereof. The Company waives all right to require the Secured Party to
proceed against any other person or to apply any Intellectual Property which the
Secured Party may hold at any time, or to marshal assets, or to pursue any other
remedy. The Company waives any defense arising by reason of the application of
the statute of limitations to any obligation secured hereby.

                  11. Term of Agreement. This Agreement and the Security
Interest shall terminate on the date on which all payments under the Notes have
been made in full and all other Obligations have been paid or discharged. Upon
such termination, the Secured Party, at the request and at the expense of the
Company, will join in executing any termination statement with respect to any
financing statement executed and filed pursuant to this Agreement.

                  12. Power of Attorney; Further Assurances.

                           (a) The Company authorizes the Secured Party, and
does hereby make, constitute and appoint it, and its respective officers,
agents, successors or assigns with full power of substitution, as the Company's
true and lawful attorney-in-fact, with power, in its own name or in the name of
the Company, to, after the occurrence and during the continuance of an Event of
Default, (i) endorse any notes, checks, drafts, money orders, or other
instruments of payment (including payments payable under or in respect of any
policy of insurance) in respect of the Intellectual Property that may come into
possession of the Secured Party; (ii) to sign and endorse any UCC financing
statement or any invoice, freight or express bill, bill of lading, storage or
warehouse receipts, drafts against debtors, assignments, verifications and
notices in connection with accounts, and other documents relating to the
Intellectual Property; (iii) to pay or discharge taxes, liens, security
interests or other encumbrances at any time levied or placed on or threatened
against the Intellectual Property; (iv) to demand, collect, receipt for,
compromise, settle and sue for monies due in respect of the Intellectual
Property; and (v) generally, to do, at the option of the Secured Party, and at
the Company's expense, at any time, or from time to time, all acts and things
which the Secured Party deems necessary to protect, preserve and realize upon
the Intellectual Property and the Security Interest granted therein in order to
effect the intent of this Agreement, the Notes and the Warrants, all as fully
and effectually as the Company might or could do; and the Company hereby
ratifies all that said attorney shall lawfully do or cause to be done by virtue
hereof. This power of attorney is coupled with an interest and shall be
irrevocable for the term of this Agreement and thereafter as long as any of the
Obligations shall be outstanding.

                           (b) On a continuing basis, the Company will make,
execute, acknowledge, deliver, file and record, as the case may be, in the
proper filing and recording places in any jurisdiction, including, without
limitation, the jurisdictions indicated on Schedule C, attached hereto, all such
instruments, and take all such action as may reasonably be deemed necessary or
advisable, or as reasonably requested by the Secured Party, to perfect the
Security Interest granted hereunder and otherwise to carry out the intent and
purposes of this Agreement, or for assuring and confirming to the Secured Party
the grant or perfection of a security interest in all the Intellectual Property.

                           (c) The Company hereby irrevocably appoints the
Secured Party as the Company's attorney-in-fact, with full authority in the
place and stead of the Company and in the name of the Company, from time to time
in the Secured Party's discretion, to take any action and to execute any
instrument which the Secured Party may deem necessary or advisable to accomplish
the purposes of this Agreement, including the filing, in its sole discretion, of
one or more financing or continuation statements and amendments thereto,
relative to any of the Intellectual Property without the signature of the
Company where permitted by law.

                  14. Other Security. To the extent that the Obligations are now
or hereafter secured by property other than the Intellectual Property or by the
guarantee, endorsement or property of any other person, firm, corporation or
other entity, then the Secured Party shall have the right, in its sole
discretion, to pursue, relinquish, subordinate, modify or take any other action
with respect thereto, without in any way modifying or affecting any of the
Secured Party's rights and remedies hereunder.

                  15. Miscellaneous.

                           (a) No course of dealing between the Company and the
Secured Party, nor any failure to exercise, nor any delay in exercising, on the
part of the Secured Party, any right, power or privilege hereunder or under the
Notes shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or thereunder preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege.

                           (b) All of the rights and remedies of the Secured
Party with respect to the Intellectual Property, whether established hereby or
by the Notes or by any other agreements, instruments or documents or by law
shall be cumulative and may be exercised singly or concurrently.

                           (c) This Agreement and the Security Agreement
constitute the entire agreement of the parties with respect to the subject
matter hereof and is intended to supersede all prior negotiations,
understandings and agreements with respect thereto. Except as specifically set
forth in this Agreement, no provision of this Agreement may be modified or
amended except by a written agreement specifically referring to this Agreement
and signed by the parties hereto.

                           (d) In the event that any provision of this Agreement
is held to be invalid, prohibited or unenforceable in any jurisdiction for any
reason, unless such provision is narrowed by judicial construction, this
Agreement shall, as to such jurisdiction, be construed as if such invalid,
prohibited or unenforceable provision had been more narrowly drawn so as not to
be invalid, prohibited or unenforceable. If, notwithstanding the foregoing, any
provision of this Agreement is held to be invalid, prohibited or unenforceable
in any jurisdiction, such provision, as to such jurisdiction, shall be
ineffective to the extent of such invalidity, prohibition or unenforceability
without invalidating the remaining portion of such provision or the other
provisions of this Agreement and without affecting the validity or
enforceability of such provision or the other provisions of this Agreement in
any other jurisdiction.

                           (e) No waiver of any breach or default or any right
under this Agreement shall be considered valid unless in writing and signed by
the party giving such waiver, and no such waiver shall be deemed a waiver of any
subsequent breach or default or right, whether of the same or similar nature or
otherwise.

                           (f) This Agreement shall be binding upon and inure to
the benefit of each party hereto and its successors and assigns.

                           (g) Each party shall take such further action and
execute and deliver such further documents as may be necessary or appropriate in
order to carry out the provisions and purposes of this Agreement.

                           (h) This Agreement shall be construed in accordance
with the laws of the State of New York, except to the extent the validity,
perfection or enforcement of a security interest hereunder in respect of any
particular Intellectual Property which are governed by a jurisdiction other than
the State of New York in which case such law shall govern. Each of the parties
hereto irrevocably submit to the exclusive jurisdiction of any New York State or
United States Federal court sitting in Manhattan county over any action or
proceeding arising out of or relating to this Agreement, and the parties hereto
hereby irrevocably agree that all claims in respect of such action or proceeding
may be heard and determined in such New York State or Federal court. The parties
hereto agree that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. The parties hereto further waive any
objection to venue in the State of New York and any objection to an action or
proceeding in the State of New York on the basis of forum non conveniens.

                           (i) EACH PARTY HERETO HEREBY AGREES TO WAIVE ITS
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
ARISING OUT OF THIS AGREEMENT. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL
ENCOMPASSING OF ANY DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO
THE SUBJECT MATER OF THIS AGREEMENT, INCLUDING WITHOUT LIMITATION CONTRACT
CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS AND ALL OTHER COMMON LAW AND
STATUTORY CLAIMS. EACH PARTY HERETO ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL
INDUCEMENT FOR EACH PARTY TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH PARTY
HAS ALREADY RELIED ON THIS WAIVER IN ENTERING INTO THIS AGREEMENT AND THAT EACH
PARTY WILL CONTINUE TO RELY ON THIS WAIVER IN THEIR RELATED FUTURE DEALINGS.
EACH PARTY FURTHER WARRANTS AND REPRESENTS THAT IT HAS REVIEWED THIS WAIVER WITH
ITS LEGAL COUNSEL, AND THAT SUCH PARTY HAS KNOWINGLY AND VOLUNTARILY WAIVES ITS
RIGHTS TO A JURY TRIAL FOLLOWING SUCH CONSULTATION. THIS WAIVER IS IRREVOCABLE,
MEANING THAT, NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, IT MAY NOT BE
MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY
SUBSEQUENT AMENDMENTS, RENEWALS AND SUPPLEMENTS OR MODIFICATIONS TO THIS
AGREEMENT. IN THE EVENT OF A LITIGATION, THIS AGREEMENT MAY BE FILED AS A
WRITTEN CONSENT TO A TRIAL BY THE COURT.

                           (j) This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original
and, all of which taken together shall constitute one and the same Agreement. In
the event that any signature is delivered by 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.

                            DEBT CONVERSION AGREEMENT

      This Debt Conversion Agreement (the "Agreement"), dated as of November 22,
2005, is entered into by and between LEXICON UNITED INCORPORATED, a Delaware
corporation having an address at 4500 Steiner Ranch Blvd, Suite 1708, Austin,
Texas 78732 (the "Company") and Keyano Invest Inc. (the "Creditor").

BACKGROUND

      On August 12, 2004, the Company issued a convertible promissory note to
the Creditor in the amount of $1,000,000 with a simple interest rate of 5% per
annum and a maturity date of August 12, 2007 (the "Note"). Under the terms of
the Note, the principal and all accrued interest is convertible to the common
stock of the Company at a conversion price of $0.25. As a result of a
one-for-four reverse split of the Company's common stock that became effective
on June 28, 2005, the conversion price of the Note became effectively $1.00. To
date, a total of $1,063,750 in principal and accrued interest remains
outstanding under the Note. In order to induce the Creditor to convert the Note
immediately, the Company is reducing the conversion price of the Note from $1.00
to $0.20 in consideration for the cancellation of the Note and the release of
the Company from all of its obligations under the Note.

      Now, THEREFORE, in consideration of the mutual promises set forth herein,
the parties hereto hereby agree as follows:

      1. Issuance of the Shares. As soon as practicable after the date hereof,
the Company shall issue shares of the Company's common stock to the Creditor at
a rate of Twenty (USD $0.20) Cents per share, or Five shares of the Company's
common stock for every One (USD$1.00) dollar (the "Shares") in consideration of
the Creditor's releases of the Company's obligation to repay the Note and in
consideration of the release set forth in Section 2 hereof. The Creditor hereby
acknowledges that the Shares shall constitute restricted stock and will contain
the standard legend that refers to the transfer restrictions of the Securities
Act of 1933, as amended.

      2. Release. In consideration of the issuance of the Shares as specified in
Section 1 hereof and for such other good and valuable consideration, the
Creditor shall release and forever discharge the Company, its subsidiaries and
affiliates (collectively, the "Releasees") from the Releasees' obligation (the
"Obligation") to repay the Note, including the principal, accrued interest, fees
or any other amounts payable thereunder and the Creditor shall not bring or
pursue any judicial, quasi-judicial or administrative action against any of the
Releasees for any reason whatsoever arising out of or otherwise relating to the
Obligation. The Creditor hereby acknowledges and agrees that it has not already
filed or otherwise commenced any such action. All of rights and obligations of
the Creditor relating to the Obligation will be governed solely by this
Agreement.

      3. Miscellaneous. The parties hereto, without the need for any additional
consideration, agree to execute such other and further instruments, documents
and agreements and to perform such other acts as may be reasonably required to
effectuate the purposes of this Agreement. This Agreement constitutes the entire
understanding among the parties hereto with respect to the subject matter hereof
and may not be amended, modified or supplemented except by a written instrument
signed by all of the parties hereto. This Agreement shall be governed by and
construed according to the laws of the State of New York without regard to the
conflicts of law principles thereof. This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original and
enforceable against the parties actually executing such counterpart, and all of
which, when taken together, shall constitute one instrument. Facsimile execution
and delivery of this letter agreement is legal, valid and binding execution and
delivery for all purposes.
