                                                                   EXHIBIT 10.13

                           (a) Subject to and upon the terms and conditions of
this Agreement, Bank shall make a Term Loan available to Borrower.

                           (b) When Borrower desires to obtain the Credit
Extension, Borrower will notify Bank by facsimile transmission or telephone no
later than 3:00 p.m. Pacific time, on the Business Day that the Credit
Extension is to be made. The notification shall be promptly confirmed by a
Payment/Advance Form in substantially the form of EXHIBIT B hereto. Bank is
authorized to make the Credit Extension under this Agreement, based upon
instructions received from a Responsible Officer or a designee of a
Responsible Officer. Bank shall be entitled to rely on any telephonic notice
given by a person who Bank reasonably believes to be a Responsible Officer or
a designee thereof, and Borrower shall indemnify and hold Bank harmless for
any damages or loss suffered by Bank as a result of such reliance. Bank will
credit the amount of the Credit Extension made under this SECTION 2.1 to
Borrower's deposit account.

                           (c) The Term Loan shall terminate on the Term
Maturity Date, at which time all Obligations under this SECTION 2.1 and other
amounts due under this Agreement (except as otherwise expressly specified
herein) shall be immediately due and payable.

         2.2      INTEREST RATES, PAYMENTS, AND CALCULATIONS.

                           (a) INTEREST RATE. Except as set forth in SECTION
2.2(B), Credit Extensions shall bear interest, on the average daily balance
thereof, at a per annum rate equal to twelve percent (12%).

                           (b) DEFAULT RATE. All Obligations shall bear
interest, from and after the occurrence of an Event of Default, at the
"Default Interest Rate." The Default Interest Rate shall be, at Bank's option,
(i) the Maximum Lawful Rate, if such Maximum Lawful Rate is established by
applicable law: or (ii) the interest rate applicable immediately prior to the
occurrence of the Event of Default plus five (5) percentage points, if no
Maximum Lawful Rate is established by applicable law: or (iii) eighteen
percent (18%) per annum: or (iv) such lesser rate of interest as Bank's, its
sole discretion may choose to charge: but never more than the Maximum Lawful
Rate or at a rate that would cause the total interest contracted for, charged
or received by Bank to exceed the Maximum Lawful Amount.

                           (c) PAYMENTS. Interest hereunder shall be due and
payable on each Payment Date. Any interest not paid when due shall be
compounded by becoming a part of the Obligations, and such interest shall
thereafter accrue interest at the rate then applicable hereunder.

                           (d) COMPUTATION.

                               (i) SPREADING OF INTEREST. Because of the
possibility of irregular periodic balances of principal, the fluctuating
nature of the interest rate, or premature payment, the total interest that
will accrue under this Agreement cannot be determined in advance. Bank does
not intend to contract for charge or receive more than the Maximum Lawful Rate
or Maximum Lawful Amount permitted by applicable state or federal law, and to
prevent such an occurrence Bank and Borrower agree that all amounts of
interest, whenever contracted for, charged or received by Bank, with respect
to the loan of money evidenced by the Loan

                                       7

<PAGE>

                                                                   EXHIBIT 10.13

Documents, shall be spread, prorated or allocated over the full period of time
the Obligations are unpaid, including the period of any renewal or extension
thereof. If the maturity of the Obligations is accelerated for any reason
whether as a lawsuit or an Event of Default or otherwise prior to the full
stated term, the total amount of interest contracted for, charged or received
to the time of such demand shall be spread, prorated or allocated along with
any interest thereafter accruing over the full period of time that the
Obligations thereafter remain unpaid for the purpose of determining if such
interest exceeds the Maximum Lawful Amount.

                               (ii) EXCESS INTEREST. At maturity (whether by
acceleration or otherwise) or on earlier final payment of the Obligations,
Bank shall compute the total amount of interest that has been contracted for,
charged or received by Bank or payable by Borrower hereunder and compare such
amount to the Maximum Lawful Amount that could have been contracted for,
charged or received by Bank. If such computation reflects that the total
amount of interest that has been contracted for, charged or received by Bank
or payable by Borrower exceeds the Maximum Lawful Amount, then Bank shall
apply such excess to the reduction of the principal balance and not to the
payment of interest: or if such excess interest exceeds the unpaid principal
balance, such excess shall be refunded to Borrower. This provision concerning
the crediting or refund of excess interest shall control and take precedence
over all other agreements between Borrower and Bank so that under no
circumstances shall the total interest contracted for, charged or received by
Bank exceed the Maximum Lawful Amount.

                               (iii) DAILY COMPUTATION OF INTEREST. To the
extent permitted by applicable law, Bank at its option may either (i)
calculate the per diem interest rate or amount based on the actual number of
days in the year (365 or 366, as the case may be), and charge that per diem
interest rate or amount each day, or (ii) calculate the per diem interest rate
or amount as if each year has only 360 days, and charge that per diem interest
rate or amount each day for the actual number of days of the year (365 or 366
as the case may be). If the Loan Documents call for monthly payments, Bank at
its option may determine the payment amount based on the assumption that each
year has only 360 days and each month has 30 days. In no event shall Bank
compute the interest in a manner that would cause Bank to contract for, charge
or receive interest that would exceed the Maximum Lawful Rate or the Maximum
Lawful Amount.

         2.3 CREDITING PAYMENTS. Prior to the occurrence of an Event of
Default, Bank shall credit a wire transfer of funds, check or other item of
payment to such deposit account or Obligation as Borrower specifies. After the
occurrence of an Event of Default, the receipt by Bank of any wire transfer of
funds, check, or other item of payment, whether directed to Borrower's deposit
account with Bank or to the Obligations or otherwise, shall be immediately
applied to conditionally reduce Obligations, but shall not be considered a
payment in respect of the Obligations unless such payment is of immediately
available federal funds or unless and until such check or other item of
payment is honored when presented for payment. Notwithstanding anything to the
contrary contained herein, any wire transfer or payment received by Bank after
12:00 noon Pacific time shall be deemed to have been received by Bank as of
the opening of business on the immediately following Business Day. Whenever
any payment to Bank under the Loan Documents would otherwise be due (except by
reason of acceleration) on a date that is not a Business Day, such payment
shall instead be due on the next Business Day, and additional fees or
interest, as the case may be, shall accrue and be payable for the period of
such extension.

         2.4 FEES. Borrower shall pay to Bank the following:

                   (a) FACILITY FEE. A Facility Fee equal to Thirty Thousand

customary fees and out-of-pocket expenses for Bank's audits of Borrower's
Accounts, and for each appraisal of Collateral and financial analysis and
examination of Borrower performed from time to time by Bank or its agents;

                   (c) BANK EXPENSES. Upon demand from Bank, including,
without limitation, upon the date hereof, all Bank Expenses incurred through
the date hereof, including reasonable attorneys' fees and expenses, and, after
the date hereof, all Bank Expenses, including reasonable attorneys' fees and
expenses, as and when they become due.

         2.5 ADDITIONAL COSTS. In case any law, after the date hereof, any
regulation, treaty or official directive or the interpretation or application
thereof by any court or any governmental authority charged with the
administration thereof or the compliance with any guideline or request of any
central bank or other governmental authority (whether or not having the force
of law):

                   (a) subjects Bank to any tax with respect to payments of
principal or interest or any other amounts payable hereunder by Borrower or
otherwise with respect to the transactions contemplated hereby (except for
taxes on the overall net income of Bank imposed by the United States of
America or any political subdivision thereof);

                   (b) imposes, modifies or deems applicable any deposit
insurance, reserve, special deposit or similar requirement against assets held
by, or deposits in or for the account of, or loans by, Bank: or

                   (c) imposes upon Bank any other condition with respect to
its performance under this Agreement, and the result of any of the foregoing
is to increase the cost to Bank, reduce the income receivable by Bank or
impose any expense upon Bank with respect to the Obligations, Bank shall
notify Borrower thereof within one hundred eighty (180) days of Bank incurring
any such reduced income or increased cost or expense. Borrower agrees to pay
to Bank the amount of such increase in cost, reduction in income or additional
expense as and when such cost, reduction or expense is incurred or determined,
upon presentation by Bank of a statement of the amount and setting forth
Bank's calculation thereof, all in reasonable detail, which statement shall be
deemed true and correct absent manifest error.

         2.6 TERM. Except as otherwise set forth herein, this Agreement shall
become effective on the Closing Date and, subject to SECTION 12.7, shall
continue in full force and effect for a term ending on the Term Maturity Date.
Notwithstanding the foregoing, Bank shall have the right to terminate its
obligation to make Credit Extensions under this Agreement immediately and
without notice upon the occurrence and during the continuance of an Event of
Default.

continuing security interest in all presently existing and hereafter acquired
or arising Collateral and all proceeds thereof, in order to secure prompt
payment of any and all Obligations and in order to secure prompt performance
by Borrower of each of its covenants and duties under the Loan Documents.
Except as set forth in the Schedule, such security interest constitutes a
valid, first priority security interest in the presently existing Collateral,
and will constitute a valid, first priority security interest in Collateral
acquired after the date hereof. Borrower acknowledges that following the
occurrence and during the continuance of an Event of Default hereunder Bank
may place a "hold" on any deposit account pledged as Collateral to secure the
Obligations. Notwithstanding termination of this Agreement, Bank's Lien on the
Collateral shall remain in effect for so long as any Obligations are
outstanding.

         4.2 DELIVERY OF ADDITIONAL DOCUMENTATION REQUIRED. Borrower shall
from time to time execute and deliver to Bank, at the request of Bank, all
Negotiable Collateral, all financing statements and other documents that Bank
may reasonably request, in form satisfactory to Bank to perfect and continue
perfected Bank's security interest in the Collateral and in order to fully
consummate all of the transactions contemplated under the Loan Documents.

         4.3 RIGHT TO INSPECT. Bank (through any of its officers, employees,
or agents) shall have the right, upon reasonable prior notice, from time to
time during Borrower's usual business hours, to inspect Borrower's Books and
to make copies thereof and to check, test, and appraise the Collateral in
order to verify Borrower's financial condition or the amount, condition of, or
any other matter relating to, the Collateral.

5.       REPRESENTATIONS AND WARRANTIES

         Borrower represents and warrants as follows:

         5.1 DUE ORGANIZATION AND QUALIFICATION. Borrower and each Subsidiary
is a corporation duly existing and in good standing under the laws of its
state of incorporation and qualified and licensed to do business in, and is in
good standing in Texas, and in any other state in which the conduct of its
business or its ownership of property requires that it be so qualified where
the failure to so qualify would result in a Material Adverse Effect.

         5.2 DUE AUTHORIZATION: NO CONFLICT. The execution, delivery, and
performance of the Loan Documents are within Borrower's powers, have been duly
authorized and are not in conflict with nor constitute a breach of any
provision contained in Borrower's Articles of Incorporation or Bylaws, nor
will they constitute an event of default under any material

                                     11

<PAGE>

                                                                   EXHIBIT 10.13

agreement to which Borrower is a party or by which Borrower is bound. Borrower
is not in default under any agreement to which it is a party or by which it is
bound, which default could have a Material Adverse Effect.

         5.3 NO PRIOR ENCUMBRANCES. Borrower has good and indefeasible title
to the Collateral free and clear of Liens, except for Permitted Liens.

         5.4 MERCHANTABLE INVENTORY. All Inventory is in all material respects
of good and marketable quality, free from all material defects.

         5.5 INTELLECTUAL PROPERTY. Borrower is the owner of the Patents,
Trademarks, Copyrights and Mask Works subject to licenses granted by Borrower
to its customers in the ordinary course of business. To Borrower's knowledge,
each of the Patents is valid and enforceable, and no part of the Intellectual
Property Collateral has been judged invalid or unenforceable, in whole or in
part, and no claim has been made that any part of the Intellectual Property
Collateral violates the rights of any third party. Except for and upon the
filing with the United States Patent and Trademark Office with respect to the
Patents and Trademarks and the Register of Copyrights with respect to the
Copyrights and Mask Works necessary to perfect the security interests created
hereunder, and except as has been already made or obtained, no authorization,
approval or other action by, and no notice to or filing with, any United
States governmental authority or United States regulatory body is required
either (i) for the grant by Borrower of the security interest granted hereby
or for the execution, delivery or performance of Loan Documents by Borrower in
the United States or (ii) for the perfection in the United States or the
exercise by Bank of its rights and remedies hereunder.

         5.6 NAME: LOCATION OF CHIEF EXECUTIVE OFFICE. Except as disclosed in
the Schedule, Borrower has not done business and will not without at least
thirty (30) days prior written notice to Bank do business under any name other
than that specified on the signature page hereof. The chief executive office
of Borrower is located at the address indicated in SECTION 10 hereof.

         5.7 LITIGATION. Except as set forth in the Schedule, there are no
actions or proceedings pending, or, to Borrower's knowledge, threatened by or
against Borrower or any Subsidiary before any court or administrative agency
in which an adverse decision could have a Material Adverse Effect on
Borrower's interest or Bank's security interest in the Collateral.

         5.8 NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS. All
consolidated financial statements related to Borrower and any Subsidiary that
have been delivered by Borrower to Bank fairly present in all material
respects Borrower's consolidated financial condition as of the date thereof
and Borrower's consolidated results of operations for the period then ended.
There has not been a material adverse change in the consolidated financial
condition of Borrower since the date of the most recent of such financial
statements submitted to Bank on or about the Closing Date.

         5.9 SOLVENCY. The fair saleable value of Borrower's assets (including
goodwill minus disposition costs) exceeds the fair value of its liabilities;
the Borrower is not left with

                                     12

<PAGE>

                                                                   EXHIBIT 10.13

unreasonably small capital after the transactions contemplated by this
Agreement; and Borrower is able to pay its debts (including trade debts) as
they mature.

         5.10 REGULATORY COMPLIANCE. Borrower and each Subsidiary has met the
minimum funding requirements of ERISA with respect to any employee benefit
plans subject to ERISA. No event has occurred resulting from Borrower's
failure to comply with ERISA that is reasonably likely to result in Borrower's
incurring any liability that could have a Material Adverse Effect. Borrower is
not an "investment company" or a company "controlled" by an "investment
company" within the meaning of the Investment Company Act of 1940. Borrower is
not engaged principally, or as one of its important activities, in the
business of extending credit for the purpose of purchasing or carrying margin
stock (within the meaning of Regulations G, T and U of the Board of Governors
of the Federal Reserve System). Borrower has complied with all the provisions
of the Federal Fair Labor Standards Act. Borrower has not violated any
statutes, laws, ordinances or rules applicable to it, violation of which could
have a Material Adverse Effect.

Collateral insured against loss or damage by fire, theft, explosion,
sprinklers, and all other hazards and risks, and in-such amounts, as
ordinarily insured against by other owners in similar businesses conducted in
the locations where Borrower's business is conducted on the date hereof.
Borrower shall also maintain insurance relating to Borrower's ownership and
use of the Collateral in amounts and of a type that are customary, to
businesses similar to Borrower's.

                           (b) All such policies of insurance shall be in such
form, with such companies, and in such amounts as are reasonably satisfactory
to Bank. All such policies of property insurance shall contain a lender's loss
payable endorsement, in a form satisfactory to Bank, showing Bank as an

give at least fifteen (15) days notice to Bank before canceling its policy for
any reason. At Bank's request, Borrower shall deliver to Bank certified copies

                           (b) Borrower shall execute and deliver such

obligation, to take, at Borrower's sole expense, any actions that Borrower is
required under this SECTION 6.7 to take but which Borrower fails to take,

after the date hereof, Borrower shall deliver to Bank a Subordination of Lien
from each Person who leases real property to Borrower in form and substance
acceptable to Bank. Borrower acknowledges and agrees that no Credit Extensions
will be made if such subordinations are not delivered by the date set forth
above.

7.       NEGATIVE COVENANTS

         Borrower covenants and agrees that, so long as any Credit Extension

Norris or Graham Glass ceases to be an employee or director of Borrower and

provided in the Stock Purchase Agreement and (ii) the Put (as defined in that
certain Warrant Subscription Agreement ("Subscription Agreement") between
Bank, Borrower, and Borrower's shareholders of even date herewith) from Bank
and as provided in the Subscription Agreement. Borrower will not, without the
prior written consent of Bank, supplement, amend, modify or waive in any way
any provision of the Stock Purchase Agreement. Borrower agrees and
acknowledges that the foregoing right of Borrower to purchase the Put Shares
is not a waiver of any Event of Default which might be created by such

other payments set forth in the first sentence of this SECTION 7.6 and as
otherwise set forth in SECTION 7.8 below.

         7.7 INVESTMENTS. Directly or indirectly acquire or own, or make any

Agreement, directly or indirectly enter into or permit to exist any material
transaction with any Affiliate of Borrower except for transactions that are in
the ordinary course of Borrower's business, upon fair and reasonable terms
that are no less favorable to Borrower than would be obtained in an arm's
length transaction with a nonaffiliated Person. Borrower agrees and
acknowledges that right of Borrower to purchase the Put Shares pursuant to and
in accordance with SECTION 7.6 above is not a waiver of any Event of Default
which might be created by such purchase, other than the general prohibition on
any material transaction with an Affiliate of Borrower set forth in the first
sentence of this SECTION 7.8 and as otherwise set forth in SECTION 7.6 above.

         7.9 INTELLECTUAL PROPERTY AGREEMENTS. Permit the inclusion in any

hereof and such other locations of which Borrower gives Bank prior written
notice and as to which Borrower signs and files a financing statement where
needed to perfect Bank's security interest.

         7.12 COMPLIANCE. Become an "investment company" or a company
controlled by an "investment company," within the meaning of the Investment
Company Act of 1940, or become principally engaged in, or undertake as one of
its important activities, the business of extending credit for the purpose of

of the foregoing.

         7.13 ABANDONMENT OF INTELLECTUAL PROPERTY. If an Event of Default

Mask Works to be abandoned, forfeited or dedicated to the public without the

calendar days of when due, any of the Obligations.

         8.2  COVENANT DEFAULT.

                           (a) If Borrower fails to perform any obligation
under SECTIONS 6.3, or 6.7 or violates any of the covenants contained in
Article 7 of this Agreement, or

                           (b) If Borrower fails or neglects to perform, keep,
or observe any other material term, provision, condition, covenant, or
agreement contained in this Agreement, in any of the Loan Documents, or in any
other present or future agreement between Borrower and Bank and as to any
default under such other term, provision, condition, covenant or agreement
that can be cured, has failed to cure such default within ten (10) days after
the occurrence thereof;

provided, however, that if the default cannot by its nature be cured within
the ten (10) day period or cannot after diligent attempts by Borrower be cured
within such ten (10) day period, and such default is likely to be cured within
a reasonable time, then Borrower shall have an additional reasonable period
(which shall not in any case exceed thirty (30) days) to attempt to cure such
default, and within such reasonable time period the failure to have cured such
default shall not be deemed an Event of Default (provided that no Credit
Extensions will be required to be made during such cure period).

         8.3 MATERIAL ADVERSE CHANGE. If there (i) occurs a material adverse
change in the business, operations, or condition (financial or otherwise) of

or priority of Bank's security interests in the Collateral;

         8.4 ATTACHMENT. If any material portion of Borrower's assets is
attached, seized, subjected to a writ or distress warrant, or is levied upon,
or comes into the possession of any trustee, receiver or person acting in a
similar capacity and such attachment, seizure, writ or distress warrant or
levy has not been removed, discharged or rescinded within thirty (30) days, or
if Borrower is enjoined, restrained, or in any way prevented by court order
from continuing to conduct all or any material part of its business affairs,
or if a judgment or other claim becomes a lien or encumbrance upon any
material portion of Borrower's assets, or if a notice of lien, levy, or
assessment is filed of record with respect to any of Borrower's assets by the
United States Government, or any department, agency, or instrumentality
thereof, or by any state, county, municipal, or governmental agency, and the
same is not paid within thirty (30) days after Borrower receives notice
thereof, provided that none of the foregoing shall constitute an Event of
Default where such action or event is stayed or an adequate bond has been
posted pending a good faith contest by Borrower (provided that no Credit
Extensions will be required to be made during such cure period).

         8.5 INSOLVENCY. If Borrower becomes insolvent, or if an Insolvency
Proceeding is commenced by Borrower, or if an Insolvency Proceeding is
commenced against Borrower and is not dismissed or stayed within forty-five
(45) days (provided that no Credit Extensions will be made prior to the
dismissal of such Insolvency Proceeding).

         8.6 OTHER AGREEMENTS. If there is a default in any agreement to which
Borrower is a party with a third party or parties resulting in the exercise of
a right by such third party or parties to accelerate the maturity of any
Indebtedness in an amount in excess of One Hundred Thousand and No/100 Dollars
($100,000.00) or that could have a Material Adverse Effect;

         8.7 SUBORDINATED DEBT. If Borrower makes any payment on account of

         8.9  JUDGMENTS. If a judgment or judgments for the payment of money in
an amount, individually or in the aggregate, of at least One Hundred Thousand
and No/100 Dollars ($100,000.00) shall be rendered against Borrower and shall
remain unsatisfied and unstayed for a period of ten (10) days (provided that no
Credit Extensions will be made prior to the satisfaction or stay of such
judgment); or

         8.10 MISREPRESENTATIONS. If any material misrepresentation or material
misstatement exists now or hereafter in any warranty or representation set forth

of which are authorized by Borrower:

                     (a) Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due
and payable (provided that upon the occurrence of an Event of Default
described in SECTION 8.5 all Obligations shall become immediately due and
payable without any action by Bank);

                     (b) Cease advancing money or extending credit to or for

                     (c) Settle or adjust disputes and claims directly with
account debtors for amounts, upon terms and in whatever order that Bank
reasonably considers advisable;

                     (d) Without notice to or demand upon Borrower, make such
payments and do such acts as Bank considers necessary or reasonable to
protect its security interest in the Collateral. Borrower agrees to assemble
the Collateral if Bank so requires, and to make the Collateral available to
Bank as Bank may designate. Borrower authorizes Bank to enter the premises
where the Collateral is located, to take and maintain possession of the
Collateral, or any part of it, and to pay, purchase, contest, or compromise
any encumbrance, charge, or lien which in Bank's determination appears to be
prior or superior to its security interest and to pay all expenses incurred
in connection therewith. With respect to any of Borrower's premises, Borrower
hereby grants Bank a license to enter such premises and to occupy the same,
without charge in order to exercise any of Bank's rights or remedies provided
herein, at law, in equity, or otherwise;

                     (e) Without notice to Borrower, set off and apply to the
Obligations any and all (i) balances and deposits of Borrower held by Bank,

Borrower held by Bank;

                     (f) Skip, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner
provided for herein) the Collateral. Bank is hereby granted a non-exclusive,
royalty-free license or other right, solely pursuant to the provisions of
this SECTION 9.1, to use, without charge, Borrower's labels, patents,
copyrights,

mask works, rights of use of any name, trade secrets, trade names,
trademarks, service marks, and advertising matter, or any property of a
similar nature, as it pertains to the Collateral, in completing production
of, advertising for sale, and selling any Collateral and, in connection with
Bank's exercise of its rights under this SECTION 9.1, Borrower's rights under
all licenses and all franchise agreements shall inure to Bank's benefit;

                     (g) Sell the Collateral at either a public or private
sale, or both, by way of one or more contracts or transactions, for cash or
on terms, in such manner and at such places (including Borrower's premises)
as Bank determines is commercially reasonable, and apply the proceeds thereof
to the Obligations in whatever manner or order it deems appropriate;

                     (h) Bank may credit bid and purchase at any public sale,
or at any private sale as permitted by law; and

                     (i) Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

                     (j) Bank shall have a non-exclusive, royalty-free
license to use the Intellectual Property Collateral to the extent reasonably
necessary, to permit Bank to exercise its rights and remedies upon the
occurrence of an Event of Default.

         9.2  POWER OF ATTORNEY. Effective only upon the occurrence and during
the continuance of an Event of Default, Borrower hereby irrevocably appoints
Bank (and any of Bank's designated officers, or employees) as Borrower's true
and lawful attorney to: (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (e) settle and adjust disputes
and claims respecting the Accounts directly with account debtors, for amounts
and upon terms which Bank determines to be reasonable; (f) modify, in its sole
discretion, any intellectual property security agreement entered into between
Borrower and Bank without first obtaining Borrower's approval of or signature to
such modification by amending Exhibit A, Exhibit B, Exhibit C and Exhibit D,
thereof, as appropriate, to include reference to any right, title or interest in
any Copyrights, Patents, Trademarks, Mask Works acquired by Borrower after the
execution hereof or to delete any reference to any right, title or interest in
any Copyrights, Patents, Trademarks, or Mask Works in which Borrower no longer
has or claims any right, title or interest; (g) file, in its sole discretion,
one or more financing or continuation statements and amendments thereto,
relative to any of the Collateral without the signature of Borrower where
permitted by law; and (h) transfer the Intellectual Property Collateral into the
name of Bank or a third party to the extent permitted under the Code provided
Bank may exercise such power of attorney to sign the name of Borrower on any of
the documents described in SECTION 4.2 regardless of whether an Event of Default
has occurred. The appointment of Bank as Borrower's attorney in fact, and each
and every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide Credit Extensions hereunder is terminated.

         9.3  ACCOUNTS COLLECTION. Upon the occurrence and during the
continuance of an Event of Default, Bank may notify any Person owing funds to
Borrower of Bank's security interest in such funds and verify the amount of
such Account. Borrower shall collect all amounts owing to Borrower for Bank,
receive in trust all payments as Bank's trustee, and if requested or required
by Bank, immediately deliver such payments to Bank in their original form as
received from the account debtor, with proper endorsements for deposit.

         9.4  BANK EXPENSES. If Borrower fails to pay any amounts or furnish
any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the
following: (a) make payment of the same or any part thereof; (b) set up such
reserves under the Term Loan as Bank deems necessary to protect Bank from the
exposure created by such failure; or (c) obtain and maintain insurance
policies of the type discussed in SECTION 6.6 of this Agreement, and take any
action with respect to such policies as Bank deems prudent. Any amounts so
paid or deposited by Bank shall constitute Bank Expenses, shall be
immediately due and payable, and shall bear interest at the then applicable
rate hereinabove provided, and shall be secured by the Collateral. Any
payments made by Bank shall not constitute an agreement by Bank to make
similar payments in the future or a waiver by Bank of any Event of Default
under this Agreement.

         9.5  BANK'S LIABILITY FOR COLLATERAL. So long as Bank complies with
reasonable banking practices, Bank shall not in any way or manner be liable
or responsible for: (a) the safekeeping of the Collateral; (b) any loss or
damage thereto occurring or arising in any manner or fashion from any cause;
(c) any diminution in the value thereof; or (d) any act or default of any
carrier, warehouseman, bailee, forwarding agency, or other person whomsoever.
All risk of loss, damage or destruction of the Collateral shall be borne by
Borrower.

         9.6  REMEDIES CUMULATIVE. Bank's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies, not expressly set forth
herein, and as provided under the Code, by law, or in equity. No exercise by
Bank of one right or remedy shall be deemed an election, and no waiver by
Bank of any Event of Default on Borrower's part shall be deemed a continuing
waiver. No delay by Bank shall constitute a waiver, election, or acquiescence
by it. No waiver by Bank shall be effective unless made in a written document
signed on behalf of Bank and then shall be effective only in the specific
instance and for the specific purpose for which it was given.

         9.7  DEMAND: PROTEST. Borrower waives demand, protest, notice of
protest, notice of default or dishonor, notice of payment and nonpayment,
notice of any default, notice of intent to accelerate, notice of
acceleration, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be
liable.

                                 EMPLOYMENT AGREEMENT

       This Employment Agreement ("AGREEMENT") is entered into as of December
30, 1998 by and between ObjectSpace, Inc., a Delaware corporation
("EMPLOYER"), and David Norris ("EXECUTIVE").

                                     WITNESSETH:

       WHEREAS, Employer is in the business of designing, developing,
implementing and selling custom computer programming services, computer
consulting, application development, system documentation, and other products
and services to a varied clientele at diverse locations;

       WHEREAS, Employer has expended and is continuing to expend considerable
time, money and effort locating and establishing long-term relationships with
customers and prospective customers and establishing and maintaining contacts
and business relationships with them, and the loss of the benefits and
potential benefits of these efforts would constitute a substantial and
irreparable injury to Employer;

       WHEREAS, Employer has expended and is continuing to expend considerable
time and money recruiting, training, making instruction available to and
compensating its employees, representatives and contractors, and the loss of
their services or potential services would constitute a substantial and
irreparable injury to Employer;

       WHEREAS, Employer desires to continue employing Executive;

       WHEREAS, Employer will provide updated confidential and proprietary
information and trade secrets to Executive after execution of this Agreement;

       WHEREAS, Executive acknowledges that the remuneration, receipt of
updated confidential and proprietary information and trade secrets after
execution of this Agreement, are adequate consideration for entry into this
Agreement, and he understands that he need not continue employment with
Employer and that he has freely chosen to enter into this Agreement;

       WHEREAS, Executive acknowledges that Employer's business involves
customers throughout North America;

       NOW, THEREFORE, in consideration of the mutual covenants and
acknowledgments contained herein, the parties agree as follows:

       1.     EMPLOYMENT AND TERM THEREOF.  Employer agrees to continue
employing Executive, and Executive agrees to continue employment, as Chief
Executive Officer.  Executive will have the duties normally associated with

                                                                   EXHIBIT 10.14

       The term of this Agreement shall commence on the date hereof and shall
terminate upon the fifth anniversary hereof, unless earlier terminated by the
termination of Executive's employment under Section 2 below; PROVIDED, that
the provisions of Sections 5, 6, 7, 8, 10, 11, 13 and 14 of this Agreement,
shall survive the termination of this Agreement for any reason.

       2.     TERMINATION OF EMPLOYMENT.  Either Employer or Executive may
terminate Executive's employment at any time, with or without Cause (defined
below) or Good Reason (defined below), (i) on eight weeks' prior written
notice by Executive to Employer if such termination is without Good Reason,
(ii) on eight weeks' prior written notice by Employer to Executive if such
termination is without Cause, or (iii) immediately upon written notice in the
case of a termination for Cause or Good Reason.  In the event that employment
is terminated by Executive for Good Reason or by Employer without Cause,
Employer will pay Executive severance pay of one year's salary at the salary
rate then in effect payable in 24 equal semi-monthly installments (the
"SEVERANCE PAYMENTS"); PROVIDED, that Executive, other than the Severance
Payments, shall not be entitled to any further benefits from the Employer;
PROVIDED, FURTHER that Executive agrees that if he fails to abide by the
provisions of Section 8, that Executive waives his rights to any and all
remaining Severance Payments, that Employer may suspend all remaining
Severance Payments, and that all other covenants, promises, duties,
obligations, releases or privileges owed to or received by Employer within
this Agreement shall remain in full force and effect and continue to inure to
the benefit of Employer.  In the event that the employment is terminated by
Executive without Good Reason or by Employer for Cause, Employer shall have no
further obligation to provide any benefits or make any payments (including
Severance Payments) to Executive except to the extent required by law.

       For purposes of this Agreement, "CAUSE" shall mean:

              (i)    any act or acts of dishonesty on the part of Executive
                     resulting in or intended to result, directly or
                     indirectly, in substantial gain or substantial personal
                     enrichment at the expense of Employer;

              (ii)   fraud, misappropriation, embezzlement, or willful and
                     material damage by Executive of or to any material
                     property of Employer or its business;

              (iii)  a good faith determination by a majority of the Board of
                     Directors of Employer that Executive has exhibited a
                     pattern or practice of willful disregard of his duties as
                     an employee of Employer;

              (iv)   the conviction of Executive of a felony;

              (v)    a material violation of this Agreement;

              (vi)   the death of Executive; or

              (vii)  the Disability (defined below) of Executive.

       As used in this Agreement, the term "GOOD REASON" shall mean the
occurrence of any of the following: (A) Employer fails to make any payment
required to be made to or for the benefit of the Executive pursuant to Section
3 of this Agreement within 10 days after written notice from Executive that
such payment is due; or (B) Employer materially breaches any of its
obligations or duties under this Agreement (other than the obligation or duty
to make payments specified in the preceding clause (A) above) which breach is

reduction in duties or title, and continues for 10 calendar days after written
notice thereof is given to Employer by the Executive.

       As used in this Agreement, the term "DISABILITY" shall mean the
circumstance that shall exist if: (i) Executive is deemed disabled pursuant to
the definition of disability under any Employer-sponsored disability insurance

notwithstanding reasonable accommodations made by Employer, the Executive
shall have been unable, unwilling or shall have failed to perform Executive's
duties under this Agreement, as determined in good faith by Employer, for a
period of 180 consecutive days, or if, in any 12-month period, the Executive
shall have been unable or unwilling or shall have failed to perform
Executive's duties for a period of 270 days, irrespective of whether or not
such days are consecutive.

       3.     COMPENSATION AND BENEFITS.   For all services by the Executive
under this Agreement, Employer shall pay the Executive a base salary at the
rate of $175,000 per year, payable on the 15th and the last day of each month,
subject to increase by the Board of Directors.

       During the Term of this Agreement, Executive shall be entitled to
participate in or receive benefits under any plan or arrangement made
generally available by Employer to its employees, subject to and on a basis
consistent with the terms, conditions and overall administration of such plans
and arrangements.  Any such plan or arrangement shall be revocable and subject
to termination or amendment at any time.

       4.     BEST EFFORTS.  Executive agrees that he will faithfully and
industriously perform all the duties required of him as Chief Executive
Officer to the reasonable satisfaction of the Board of Directors of Employer
and that he will devote his full business time to the business of Employer and
that the amount of such time will be consistent with Employer's reasonable
practice.

       5.     INVENTIONS.  Executive agrees to disclose promptly, completely
and in writing to Employer any invention, discovery, process, design, diagram,
method, apparatus or improvement, whether patentable or not, whether
implemented or not, which Executive develops or discovers individually or with
others during the performance of Executive's duties for Employer or using or
influenced by Employer's time, data, facilities or materials (all hereinafter
called "INVENTIONS"). Executive's obligations under this Section apply
regardless of whether an idea for an Invention occurs to Executive on the job,
at home, or elsewhere.  Executive further agrees that all Inventions are
Employer's exclusive property, whether or not patent applications are filed on
them.

                                     -3-

       Executive will assist Employer at any time during or after Executive's
employment, at Employer's expense, in the preparation, execution, and delivery
of any disclosures, patent applications or papers required to obtain patents
for Inventions, and in connection with any other proceedings that may be
necessary to enforce Employer's rights in Inventions against others or to vest
title to them in Employer.  If such assistance takes place after Executive's
employment is terminated, Employer will pay Executive at a reasonable rate.

       6.     REPRESENTATIONS:  Executive agrees not to use ObjectSpace's name
in sponsorship or for gain, except pursuant to the performance of Executive's
duties for Employer, without prior written approval of the Board of Directors
of Employer.

       7.     COPYRIGHTS.  Executive agrees that Employer will be the
copyright proprietor in all copyrightable works created or developed by
Executive individually or with others pursuant to Executive's employment with
Employer.

       Executive further agrees, if so requested and at no further expense to
Employer, to execute in writing any acknowledgments or assignments of
copyright ownership of works within this Agreement as may be necessary for the
preservation of the worldwide proprietorship in Employer of such copyrights.

       8.     PROTECTIONS OF EMPLOYER'S INTERESTS.

              (a)    NON-COMPETE.  During the period that the Executive is
       employed by the Employer and for a period of one year following the
       termination of employment for any reason, the Executive agrees that the
       Executive will not (i) own or have any interest in, or act as a manager,
       officer, director, executive, consultant, agent or representative of, or
       assist in any way or in any capacity, any person, firm, association,
       partnership, corporation, limited liability company or other entity that
       (a) manufactures, distributes or sells products in competition with the
       Employer's Products, as hereinafter defined, anywhere within North
       America or (b) solicit business in competition with the Employer from
       (y) any customers of the Employer who transacted business with the
       Employer during the one year period prior to such termination with whom
       the Executive or his direct reports had contact or (z) any potential
       customers of the Employer with whom the Executive or his direct reports
       had contact during the one year period prior to such termination.  As
       used herein, the term "PRODUCTS" means the same or similar products or
       services as the Employer currently provides, including, but not limited
       to a line of "middleware" products known as "Voyager" and
       object-oriented consulting and training services.  The Executive
       acknowledges and agrees that the Employer sells its Products throughout
       North America and, therefore, the geographic scope of the restriction
       contained herein is both reasonable and necessary under the
       circumstances.  Notwithstanding anything in this Section 8(a) to the
       contrary, in the event employment is terminated by Employer without
       Cause or by Executive for Good Reason, Executive shall be entitled to
       provide training and consulting services to any Persons other than the
       customers and potential customers identified in clauses (b)(y) and
       (b)(z) of this Section 8(a).

                                                                   EXHIBIT 10.14

              (b)    NON-SOLICITATION.  During Executive's employment with
       Employer and for two years thereafter, Executive will not directly or
       indirectly, whether for himself or any other person or entity, employ,
       hire, solicit or try to entice away any person who (1) was an employee
       or independent contractor of Employer during Executive's employment by
       Employer, or (2) was employed by any customer of Employer and with whom
       Executive had direct contact during Executive's employment with
       Employer.

              (c)    BUSINESS OPPORTUNITY.  Executive agrees that given the
       relationship between the parties, the restrictions in Sections 8(a) and
       8(b) contain reasonable restrictions of time, geographical area, and
       scope of activity and that these restrictions do not impose any greater
       restraint than is necessary to protect the goodwill and other legitimate
       business interests of Employer, including but not limited to the
       personal goodwill developed by Executive with Employer's clients or
       customers and the protection of Employer's trade secrets, proprietary
       information and know-how.  Executive further agrees that the
       restrictions in Sections 8(a) and 8(b) will not prevent him from
       obtaining gainful employment or cause him undue hardship.

              (d)    CONFIDENTIALITY.  Executive acknowledges that Employer's
       trade secrets, proprietary information and know-how are valuable,
       special and unique assets of Employer's business, access to and
       knowledge of which are essential to the performance of Executive's
       duties hereunder. Executive agrees to keep confidential, except as the
       Board of Directors of Employer may otherwise consent in writing, and
       not to disclose, or make any use of except for the benefit of the
       Employer, at any time either during or after his employment, any trade
       secrets, proprietary information or know-how of the Employer, including
       but not limited to that which relates to the Employer or the Employer's
       research, services, development, processes, designs, formulas, test
       data, purchasing, accounting, customer lists, business plans, marketing
       plans and strategies, pricing strategies, internal operating
       procedures, written materials provided to third parties by agreement,
       implementation techniques of Employer programs, or other subject matter
       pertaining to any business of the Employer or any of its clients,
       customers, consultants, licensees, or affiliates that Executive may
       produce, obtain or otherwise acquire during his employment, except as
       provided herein. Executive further agrees not to deliver or allow to be
       delivered trade secrets, proprietary information or know-how to third
       parties without the consent of an authorized representative of the
       Board of Directors of Employer.  Executive further agrees that he will
       not use or disclose to Employer confidential information belonging to
       his former employers.

              (e)    DISCLOSURE.  Executive will make the terms and conditions
       of this Agreement known to any business, entity or person engaged in
       activities competitive with Employer's business with which he becomes
       associated.  Employer will have the right to make the terms of this
       confidentiality agreement known to third persons.

              (f)    EMPLOYER DOCUMENTS.  At the time of Executive's
       termination or upon demand by the Board of Directors of Employer
       (whichever is sooner), Executive will promptly turn over to Employer
       all files, documents, business records, lists of customers and
       potential customers, promotional materials, internal operating reports,
       names and addresses of executives and potential executives, customer
       strategy information,

                                                                   EXHIBIT 10.14

       employment and payroll records, marketing information, manuals, billing
       reports, pricing information and strategies, management methods and
       systems, contracts with customers, subcontractors and others,
       correspondence, resumes of existing and potential executives, customer
       bids and proposals, books and records, and any other records,
       documents, writings of any kind whatsoever, and all assets of any kind
       whatsoever that belong to Employer.  Further, Executive will not copy
       or record in any manner whatsoever the information contained in the
       foregoing materials, and Executive will turn over to Employer any
       copies or recordings of any kind whatsoever containing information
       derived directly or indirectly from such materials.

              (g)    ENFORCEMENT. The parties agree that if there is a breach
       or threatened breach by Executive of any of the provisions of this
       Section 8, Employer will be entitled to injunctive relief restraining
       Executive, as any breach or threatened breach would cause irreparable
       injury to Employer for which there would be no adequate remedy at law.
       Nothing herein prohibits Employer from pursuing other remedies
       available for any breach or threatened breach, including the recovery
       of damages from Executive. Should any provision of this Section 8 be
       held unreasonably broad in its restrictions as to time, geographical
       area, or scope of activity, the provision will be limited as necessary
       to render it reasonable.

              (h)    CONSTRUCTION.  The covenants of Executive contained in
       this Section 8 will be construed as an agreement independent of any
       other provision of this Agreement, and the existence of any claim or
       cause of action of Executive against Employer, whether predicated on
       this Agreement or otherwise, will not constitute a defense to the
       enforcement by Employer of said covenants.

       9.     COMMUNICATIONS:  All communications to Employer pursuant to this
Agreement must be in writing and addressed to:

              ObjectSpace, Inc.

short sale of, loan, pledge, exercise any option for the purchase of or
otherwise dispose of any securities of Employer (other than those included in

underwriter reasonably requests not to exceed 180 days) from the effective

to cause Employer to register any securities for the Executive's own account
for such period as Employer continues to delay such demand registration
pursuant to Section 2(d) of the Investor Rights Agreement.

       12.    LOAN.  Employer shall loan to Executive $150,000 upon the
closing of the transactions set forth in that certain Purchase Agreement to be

       13.    ARBITRATION.

              (a)    INTRODUCTION.  Executive recognizes that differences may
       arise between the Employer and Executive during or following Executive's
       employment with the Employer, and that those differences may or may not
       be related to Executive's employment with the Employer.  Executive
       understands and agrees that the Employer is engaged in transactions
       involving interstate commerce and that Executive's employment with
       Employer involves such commerce.  Executive understands and agrees that
       by agreeing to arbitration hereunder, the Executive anticipates gaining
       the benefits of speedy, impartial dispute resolution of any Claim (as
       defined below).

                                     -7-

                                                                   EXHIBIT 10.14

              (b)    AGREEMENT TO ARBITRATE.  In the event there is any dispute,
       claim, or controversy, whether or not arising out of Executive's
       employment, its termination, or this Agreement and regardless of the kind
       or type of dispute, claim or controversy (excluding claims for workers'
       compensation, unemployment compensation benefits and claims by the
       Employer for injunctive and/or other equitable relief) that the Employer
       may have against Executive or that Executive may have against the
       Employer or against its directors, officers, stockholders, employees,
       affiliates, representatives, or agents in their capacity as such or
       otherwise (all such disputes, claims or controversies being collectively
       referred to as "CLAIMS"), the Executive and the Employer agree to submit
       all such Claims to final and binding arbitration pursuant to the
       provisions of the Federal Arbitration Act, upon a request submitted in
       writing to the Board of Directors of Employer within two years of the
       date when the aggrieved party has knowledge of the event giving rise to
       the claim, or within two years of the termination of employment,
       whichever occurs first.  Except as provided in Sections 13(c) and 13(d)
       hereof, arbitration shall be the sole and exclusive remedy for all Claims
       covered by this Agreement, and any failure to request arbitration timely
       shall constitute a waiver of all rights to raise any Claims in any forum,
       even if there is a federal or state statute of limitations that would
       have given more time to pursue the Claim.  The limitations period set
       forth in this paragraph shall not be subject to tolling, equitable or
       otherwise.

              (c)    CLAIMS COVERED.  The Claims covered by this Agreement
       include, but are not limited to, claims for wages or other compensation
       due; claims for breach of any contract or covenant (express or implied);
       tort claims (including, but not limited to, assault, battery, defamation,
       slander, retaliation for filing a workers' compensation claim,
       retaliation for reporting a criminal act, negligent
       hiring/training/supervision/retention, emotional distress (whether
       negligently, gross negligently, or intentionally inflicted), invasion of
       privacy); claims for discrimination or retaliation (including, but not
       limited to, race, sex, sexual harassment, sexual orientation, religion,
       national origin, age, pregnancy, leave of absence, marital status, or
       medical condition, handicap or disability); claims for benefits (except
       where an employee benefit or retirement plan specifies that its claims
       procedure shall culminate in an arbitration procedure different from this
       one); and claims for violation of any federal, state, or other
       governmental law, statute, regulation, or ordinance, except claims
       excluded in Section 13(d).  Executive understands that this Section 13
       covers Claims not only against the Employer, but all other potential
       defendants, including but not limited to co-employees, managers,
       supervisors, directors, officers, stockholders, joint employers,
       representatives, agents, and parent, subsidiary, affiliated and successor
       companies.  Further, Executive understands that Executive is not waiving
       Executive's right to pursue a charge at any time with the National Labor
       Relations Board or any other federal, state or city agency.

              (d)    CLAIMS NOT COVERED.  Claims Executive may have for workers'
       compensation benefits or unemployment compensation benefits are not
       covered by this Section 13.  Further, Claims by the Employer for
       injunctive and/or other equitable relief are also not covered, including
       but not limited to claims for unfair competition (including, but not
       limited to, violations of Sections 8) and/or the use and/or unauthorized
       disclosure of trade secrets or confidential information, as to which

                                                                   EXHIBIT 10.14

       Executive understands and agrees that the Employer may seek and obtain
       relief from a court of competent jurisdiction.

              (e)    PROCEDURE.  All Claims will be resolved by a single
       arbitrator in Dallas, Texas in accordance with the National Rules for the
       Resolution of Employment Disputes of the American Arbitration Association
       (the "AAA"), as amended, modified or revised.  The arbitrator shall apply
       federal and/or Texas substantive law, as appropriate to the particular
       claims presented.  Judgment upon the award rendered by the arbitrator may
       be entered in any court having jurisdiction.  To the extent this
       Section 13 and the rules of the AAA conflict, this Section shall prevail.

              (f)    THE ARBITRATOR'S AUTHORITY.  The arbitrator shall only have
       those powers authorized by statute or enumerated below:

              (i)    Rule on motions regarding the pleadings and discovery;

              (ii)   Issue protective orders on the motion of any party or third
                     party witness.  Such protective orders may include, but are
                     not limited to, sealing the record of the arbitration, in
                     whole or in part (including discovery proceedings and
                     motions, transcripts and the decision and award), to
                     protect the privacy or other constitutional or statutory
                     rights of parties and/or witnesses;

              (iii)  Determine only the Claim submitted to the arbitrator.  The
                     Claim shall be identified in any request for arbitration,
                     any counterclaim(s), and the answer(s) thereto.  Any Claim
                     not identified in those pleadings is outside the scope of
                     the arbitrator's jurisdiction and any award invoking such
                     Claims is subject to a motion to vacate; PROVIDED, HOWEVER,
                     that the arbitrator shall have exclusive authority to
                     resolve any Claim relating to the validity, interpretation,
                     application, and enforcement of this Section 13; and

              (iv)   The arbitrator shall only be authorized to exercise powers
                     specifically enumerated by this Agreement and to decide the
                     Claim in accordance with governing principles of law and
                     equity.  The arbitrator shall not have any authority to
                     modify the powers granted to the arbitrator by the terms of
                     this Agreement.  The arbitrator also shall not have the
                     authority to modify a party's responsibility for fees and
                     costs as set forth below, except as required by law.

              (g)    COSTS OF ARBITRATION.  If a party chooses to be represented
       by an attorney (or other representative) during the arbitration, that
       party shall be responsible for its own attorneys' fees, except as
       provided by law.  Each party shall be responsible for one-half the cost
       of the court reporters' fees, the AAA's filing fee, the arbitrator's fee,
       the cost of the arbitrator's transcript of the hearing and any costs
       associated with the facilities for the arbitration (E.G., the hearing
       room).  Each party shall be responsible for all costs associated with
       discovery which that party initiates (E.G., depositions), except

                                       -9-

       that a party or third party witness being deposed shall be responsible
       for the cost of a copy of the transcript if he chooses to order a copy.

       14.    GENERAL PROVISIONS

              (a)    ENTIRE AGREEMENT.  This Agreement supersedes, replaces and
       merges any and all prior and contemporaneous understandings,
       representations, agreements and discussions relating to the same or
       similar subject matter as that of this Agreement and constitutes the
       entire agreement between Executive and Employer about the subject matter
       of this Agreement.

              (b)    NO CONFLICT.  Executive represents and warrants that he is
       not under any legal or contractual obligation that would conflict with
       the obligations and duties he is undertaking herein, and that his
       execution of this Agreement will not breach any agreement to which he is
       a party.

              (c)    SEVERABILITY.  If any provision of this Agreement is held
       unenforceable under present or future laws, the provision will be
       severable, and this Agreement will be construed and enforced as if the
       unenforceable provision never comprised a part of it.  Furthermore, in
       lieu of the unenforceable provision, there will be added automatically a
       provision as similar in its terms to the unenforceable provision as may
       be enforceable.
