Executive's target performance bonus under the Performance Bonus Plan. For
calendar year 2002, the Executive shall be eligible for a target bonus of 55.26%
of Base Salary for the period ending December 31, 2002, if the Executive and the
Employer have achieved certain defined and documented annual goals. If the
Executive and the Employer overachieve these goals, the bonus may be as high as

current Base Salary for each six (6) month period if the Executive and the
Employer have achieved certain defined and documented annual goals. If the
Executive and the Employer overachieve these goals, this reward may be set as a
higher percentage of Base Salary for each such six (6) month period. The Board

its sole discretion.

        C. During the term of this Agreement, the Employer shall:

           (1) include the Executive in any life insurance, disability
        insurance, medical, dental or health insurance, savings, pension and
        retirement plans, employee stock option and stock purchase plans, and
        other benefit plans or programs (including, if applicable, any excess
        benefit or supplemental executive retirement plans) maintained by the
        Employer for the benefit of its executives;

           (2) include the Executive in such perquisites as the Employer may
        establish from time to time that are commensurate with his position and
        at least comparable to those received by other executives of the
        Employer; and

           (3) provide the Executive with such amount of paid time off per annum
        as is provided under the Employer's standard employment policies.

     7. Expenses. The Employer shall reimburse the Executive for all reasonable
and approved business expenses, provided the Executive submits paid receipts or
other documentation acceptable to the Employer and as required by the Internal
Revenue Service to qualify as ordinary and necessary business expenses under the
Internal Revenue Code of 1986, as amended (the "Code").

     8. Termination. The Executive's services shall terminate upon the first to
occur of the following events:

        A. At the end of the term of this Agreement, including any Renewal
Terms, as set forth in Paragraph 5 of this Agreement.

        B. Upon the Executive's date of death or the date the Executive is given
written notice that he has been determined to be disabled by the Employer. For
purposes of this Agreement, the Executive shall be deemed to be disabled if the
Executive meets the requirements for long term disability under the Employer's
long-term disability plan or program in effect on

Page 3                                         MetaSolv Confidential Information

<PAGE>

the date of the notice; alternatively, if the Employer does not have such a
long-term disability plan or program in effect, then the Executive shall be
deemed to be disabled if the Executive, as a result of illness or incapacity,
shall be unable to perform substantially his required duties for a period of
four (4) consecutive months or for any aggregate period of six (6) months in any
twelve (12) month period. A termination of the Executive's employment by the
Employer for disability shall be communicated to the Executive by written notice
and shall be effective on the tenth (10th) business day after receipt of such
notice by the Executive, unless the Executive returns to full-time performance
of his duties before such tenth (10th) business day.

        C. On the date the Employer provides the Executive with written notice
that he is being terminated for "Cause." For purposes of this Agreement, and as
determined by the Employer in its sole discretion, the Executive shall be deemed
terminated for Cause if the Employer terminates the Executive after the
Executive:

           (1) shall have been convicted of any felony including, but not
        limited to, a felony involving fraud, theft, misappropriation,
        dishonesty, or embezzlement;

           (2) shall have committed intentional acts of misconduct that
        materially impair the goodwill or business of the Employer or cause
        material damage to its property, goodwill, or business; or

           (3) shall have refused to, or willfully failed to, perform his
        material duties hereunder; provided, however, that no termination under
        this subparagraph (3) shall be effective unless the Executive does not
        cure such refusal or failure to the Employer's reasonable satisfaction
        as soon as practicable after the Employer gives the Executive written
        notice identifying such refusal or failure (and, in any event, within
        thirty (30) days after receipt of such written notice).

No act or failure to act on the part of the Executive shall be considered
"willful" unless it is done, or omitted to be done, by the Executive in bad
faith or without reasonable belief that his action or omission was in the best
interests of the Employer. A termination of the Executive's employment for Cause
shall be effected in accordance with the following procedures. The Board shall
give the Executive written notice ("Notice of Termination for Cause") of its
intention to terminate the Executive's employment for Cause, setting forth in
reasonable detail the specific conduct of the Executive that it considers to
constitute Cause and the specific provision(s) of this Agreement on which it
relies, and stating the date, time and place of the Board Meeting for Cause. The
"Board Meeting for Cause" means a meeting of the Board at which the Executive's
termination for Cause will be considered, that takes place not less than ten
(10) and not more than twenty (20) business days after the Executive receives
the Notice of Termination for Cause. The Executive shall be given an
opportunity, together with counsel, to be heard at the Board Meeting for Cause.
The Executive's termination for Cause shall be effective when and if a
resolution is duly adopted at the Board Meeting for Cause by a two-thirds
majority vote of the entire membership of the Board, excluding the Executive
from the count of such membership, stating that in the good faith opinion of the
Board, the Executive is guilty of the conduct described in the Notice of
Termination for Cause, and that such conduct constitutes Cause under this
Agreement.

        D. On the date the Employer terminates the Executive's employment for
any reason, other than a reason otherwise set forth in this Paragraph 8,
provided that the Employer shall give the Executive thirty (30) days written
notice prior to such date of its intention to terminate such employment.

        E. On the date the Executive terminates his employment for "Good
Reason." For purpose of this Agreement, Good Reason means:

           (1) a change in the Executive's status, title, position or
        responsibilities (including reporting responsibilities) materially
        inconsistent with Paragraph 3 of this Agreement; or the assignment to
        the Executive of any duties or responsibilities materially inconsistent
        with Paragraph 3 of this Agreement.

           (2) the Employer's requiring the Executive to be based at any place
        outside a 60-mile radius of the location of the Employer's corporate
        headquarters as of the date of this Agreement, except for reasonably
        required travel;

           (3) following a Change in Control (as defined in this Paragraph 8E),
        the failure by the Employer to (a) continue in effect (without reduction
        in benefit levels and/or reward opportunities) any material compensation
        or employee benefit plan in which the Executive was participating at any
        time within ninety (90) days preceding the date of a Change in Control
        or at any time thereafter, unless such plan is replaced with a plan that
        provides substantially equivalent compensation or benefits to the
        Executive or (b) provide the Executive with compensation and benefits,
        in the aggregate, at least equal (in terms of benefit levels and/or
        reward opportunities) to those provided for under each other employee
        benefit plan, program and practice in which the Executive was
        participating at any time within ninety (90) days preceding the date of
        a Change in Control or at any time thereafter;

           (4) any material breach by the Employer of any provision of this
        Agreement; or

           (5) following a Change in Control (as defined in this Paragraph 8E),
        the failure of the Employer to obtain an agreement, satisfactory to the
        Executive, from any Successors and Assigns (as defined herein) to assume
        and agree to perform this Agreement.

Any event or condition described in this Paragraph 8E that occurs prior to a
Change in Control, but which the Executive reasonably demonstrates (1) was at
the request of a third party, or (2) otherwise arose in connection with, or in
anticipation of, a Change in Control that actually occurs, shall constitute Good
Reason for purposes of this Agreement notwithstanding that it occurred prior to
the Change in Control.

For purposes of this Agreement, a "Change in Control" means the first to occur
of (a) the completion of the acquisition by any entity, person, or group of
beneficial ownership, as that term is defined in Rule 13d-3 under the Securities
Exchange Act of 1934, of more than 50% of the

Page 5                                         MetaSolv Confidential Information

<PAGE>

outstanding capital stock of the Employer entitled to vote for the election of
directors ("Voting Stock"); (b) the completion by any entity, person or group
(other than the Employer or an affiliate of the Employer) of a tender offer or
an exchange offer for more than 50% of the outstanding Voting Stock of the
Employer; (c) the effective time of (1) a merger or consolidation of the
Employer with one or more corporations as a result of which the holders of the
outstanding Voting Stock of the Employer immediately prior to such merger or
consolidation hold less than 50% of the Voting Stock of the surviving or
resulting corporation, or (2) a transfer of substantially all of the property or
assets of the Employer other than to an entity of which the Employer owns at
least 80% of the Voting Stock; and (d) the election to the Board, without the
recommendation or approval of the incumbent Board, of the lesser of (1) three
directors, or (2) directors constituting a majority of the number of directors
of the Employer then in office.

For purposes of this Agreement, "Successors and Assigns" shall mean a
corporation or other entity acquiring all or substantially all of the stock,
assets and/or business of the Employer whether by operation of law or otherwise.

A termination by the Executive for Good Reason shall be effected in accordance
with the following procedures. The Executive shall give the Board written notice
("Notice of Termination for Good Reason") of his termination of employment for
Good Reason, setting forth in reasonable detail the specific conduct of the
Employer that the Executive considers to constitute Good Reason and the specific
provision(s) of this Agreement on which the Executive relies. The Executive's
termination shall be effective immediately upon delivery of the Notice of
Termination for Good Reason; however, the Executive shall not receive the
payment set forth in Paragraph 9C until expiration of the cure period provided
below. During the fifteen days immediately following the delivery of the Notice
of Termination for Good Reason the Employer shall have the opportunity to cure
the Good Reason for termination specified in the Executive's Notice of
Termination for Good Reason. In the event that the Employer cures the Good
Reason for termination in all material respects prior to the expiration of the
fifteen-day cure period and notifies the Executive in writing of such cure, the
Executive's termination of this Agreement shall be null and void, this Agreement
shall be revived as if it were never terminated, the Executive will not receive
the payment set forth in Paragraph 9C, and the Executive shall be required to
resume employment retroactive to the termination date and fulfill his
obligations under this Agreement. Upon receipt of the Employer's written notice
that the termination for Good Reason has been cured, the Executive shall deliver
to the Employer written confirmation of his resumption of employment within five
days of receiving Employer's written notice of cure. A failure do deliver such
written notice shall be deemed a breach of this Agreement. In the event the
Board disagrees that Good Reason exists for the Executive to terminate, the
Board shall so notify the Executive within fifteen days of receipt of the Notice
of Termination for Good Reason. In the event that the Employer does not (i) cure
the Good Reason for termination in the manner provided above or (ii) notify the
Executive that the Board disagrees that Good Reason exits for termination, the
Executive shall be entitled to receive the payment set forth in Paragraph 9C.

        F. Upon the expiration of 120 days after the Executive gives the
Employer written notice of his or her termination of employment with the
Employer on grounds other than for Good Reason.

     9. Compensation Upon Termination.

        A. If the Executive's services are terminated pursuant to Paragraph 8A,
8B, 8C, or 8F, the Executive shall be entitled to his salary through his final
date of active employment plus any accrued but unused current paid time off for
which the Executive is eligible. The Executive shall also be entitled to any
benefits mandated under the Consolidated Omnibus Budget Reconciliation Act of
1985 (COBRA) or required under the terms of any death, insurance, or retirement
plan, program, or agreement provided by the Employer and to which the Executive
is a party or in which the Executive is a participant, including, but not
limited to, any short-term or long-term disability plan or program, if
applicable.

        B. Except as otherwise provided in Paragraph 9A, 9C or this Paragraph
9B, if the Executive's services are terminated pursuant to Paragraph 8D or 8E,
the Executive shall be entitled to his salary through his final date of active
employment, plus any accrued but unused current paid time off for which the
Executive is eligible. The Executive also shall be entitled to a single sum
payment payable within thirty (30) days after the Executive's termination date
and equal to one (1) times his Base Salary, plus one (1) times his annual target
performance bonus as determined pursuant to the Employer's Performance Bonus
Plan, provided (a) he signs an agreement acceptable to the Employer that (i)
waives any rights the Executive may otherwise have against the Employer, (ii)
releases the Employer from actions, suits, claims, proceedings and demands
related to the period of employment and/or the termination of employment, and
(iii) contains certain other obligations which shall be set forth at the time of
the termination (including, but not limited to, a reaffirmation of the
Executive's obligations under Paragraph 10 of this Agreement), and (b) the
Employer shall be permitted to offset from the severance pay hereunder any
salary paid to the Executive during the thirty (30) day or one (1) year written
notice period, whichever is applicable, if the Executive performs no substantial
services during such thirty (30) day or one (1) year written notice period. In
addition, all options to purchase common stock of the Employer granted to the
Executive pursuant to the Employer's Long-Term Incentive Plan shall immediately
become Vested Shares as defined in any Stock Option Agreement(s) between the
Employer and the Executive, and the Executive shall have one (1) year following
the date of termination to exercise any unexercised options held by him as of
such date. The Employer shall also pay for up to six (6) months of outplacement
services for the Executive (or, if earlier, until the Executive obtains
full-time employment), to be provided by an outplacement service provider
selected by the Employer. Additionally, the Executive shall be entitled to any
benefits mandated under COBRA or required under the terms of any death,
insurance, or retirement plan, program, or agreement provided by the Employer
and to which the Executive is a party or in which the Executive is a
participant. If the Executive elects COBRA continuation coverage for himself
and/or his dependents, the Employer shall pay for such coverage for so long as
the Executive is eligible for COBRA continuation coverage; provided however,
that nothing herein shall be construed to extend the period of time mandated by
statute over which such COBRA continuation may otherwise be provided to the
Executive and/or his dependents.

        C. If the Executive's services are terminated pursuant to Paragraph 8D
or 8E at any time during the twenty-four (24) month period following a Change in
Control, the

Page 7                                         MetaSolv Confidential Information

<PAGE>

Executive shall be entitled to his salary through his final date of active
employment, plus any accrued but unused current paid time off for which the
Executive is eligible. In lieu of any entitlements under Paragraph 9B, the
Executive shall be entitled to a single sum payment payable within thirty (30)
days after the Executive's termination date and equal to two (2) times his Base
Salary, plus two (2) times his annual target performance bonus as determined
pursuant to the Employer's Performance Bonus Plan, provided (a) he signs an
agreement acceptable to the Employer that (i) waives any rights the Executive
may otherwise have against the Employer, (ii) releases the Employer from
actions, suits, claims, proceedings and demands related to the period of
employment and/or the termination of employment, and (iii) contains certain
other obligations which shall be set forth at the time of the termination
(including, but not limited to, a reaffirmation of the Executive's obligations
under Paragraph 10 of this Agreement), and (b) the Employer shall be permitted
to offset from the severance pay hereunder any salary paid to the Executive
during the thirty (30) day or one (1) year written notice period, whichever is
applicable, if the Executive performs no substantial services during such thirty
(30) day or one (1) year written notice period. In addition, all options to
purchase common stock of the Employer granted to the Executive pursuant to the
Employer's Long-Term Incentive Plan shall immediately become Vested Shares as
defined in any Stock Option Agreement(s) between the Employer and the Executive,
and the Executive shall have one (1) year following the date of termination to
exercise any unexercised options held by him as of such date. The Employer shall
also pay for up to six (6) months of outplacement services for the Executive
(or, if earlier, until the Executive obtains full-time employment), to be
provided by an outplacement service provider selected by the Employer.
Additionally, the Executive shall be entitled to any benefits mandated under
COBRA or required under the terms of any death, insurance, or retirement plan,
program, or agreement provided by the Employer and to which the Executive is a
party or in which the Executive is a participant. If the Executive elects COBRA
continuation coverage for himself and/or his dependents, the Employer shall pay
for such coverage for so long as the Executive is eligible for COBRA
continuation coverage; provided however, that nothing herein shall be construed
to extend the period of time mandated by statute over which such COBRA
continuation may otherwise be provided to the Executive and/or his dependents.

        D. If a "change in control" shall occur (as defined in Section
280G(b)(2)(a)(i) of the Code), and a determination is made by legislation,
regulation, ruling directed to the Executive or the Employer, or court decision,
that the aggregate amount of any payment made to the Executive hereunder, or
pursuant to any plan, program, or policy of the Employer in connection with, on
account of, or as a result of, such change in control constitutes "excess
parachute payments" under the Code that are subject to the excise tax provisions
of Section 4999 of the Code, or any successor sections thereof, the Executive
shall be entitled to receive from the Employer, in addition to any other amounts
payable hereunder, an additional payment (a "Gross-Up Payment") in an amount
such that after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes, other than interest and penalties
imposed by reason of the Executive's failure to file timely a tax return or pay
taxes shown due on his return), including, without limitation, any income taxes
(and any interest and penalties imposed thereon) and any excise tax imposed upon
the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment
equal to the excise tax imposed; provided, however, if the aggregate amount of
payments to the Executive, without regard to the Gross-Up

Page 8                                         MetaSolv Confidential Information

<PAGE>

Payment, does not exceed one hundred ten percent (110%) of the maximum amount
that the Executive could receive without regard to the payments being subject to
the excise tax provisions of Section 4999 of the Code (the "Tax Limit"), then
(i) no Gross-Up Payment shall be made hereunder, and (ii) the payments shall be
reduced to the Tax Limit. All determinations required to be made under this
Paragraph 9, including whether and when a Gross-Up Payment is required and the
amount of such Gross-Up Payment and the assumptions to be utilized in arriving
at such determination, shall be made by a certified public accounting firm
designated by the Employer and reasonably acceptable to the Executive which is
one of the five largest accounting firms in the United States (the "Accounting
Firm"), which shall provide detailed supporting calculations both to the
Employer and the Executive within fifteen (15) business days of the receipt of
notice from the Executive that there has been an excess parachute payment, or
such earlier time as is requested by the Employer. All fees and expenses of the
Accounting Firm shall be borne solely by the Employer. Any Gross-Up Payment, as
determined pursuant to this Paragraph 9 shall be paid by the Employer to the
Executive within five (5) days of the receipt of the Accounting Firm's
determination. As a result of the uncertainty in the application of Section 4999
of the Code at the time of the initial determination by the Accounting Firm
hereunder, it is possible that Gross-Up Payments which will not have been made
by the Employer should have been made ("Underpayment") consistent with the
calculations required to be made hereunder. In the event that the Employer
exhausts its remedies hereunder and the Executive thereafter is required to make
a payment of any excise tax, the Accounting Firm shall determine the amount of
the Underpayment that has occurred and any such Underpayment shall be promptly
paid by the Employer to or for the benefit of the Executive. The Executive shall
notify the Employer in writing of any claim by the Internal Revenue Service
that, if successful, would require the payment by the Employer of the Gross-Up
Payment. Such notification shall be given as soon as practicable but no later
than ten (10) business days after the Executive is informed in writing of such
claim and shall apprise the Employer of the nature of such claim and the date on
which such claim is requested to be paid. The Executive shall not pay such claim
prior to the expiration of the thirty (30) day period following the date on
which he gives such notice to the Employer (or such shorter period ending on the
date that any payment of taxes with respect to such claim is due). If the
Employer notifies the Executive in writing prior to the expiration of such
period that it desires to contest such claim, the Executive shall:

           (1) give the Employer any information reasonably requested by the
        Employer relating to such claim;

           (2) take such action in connection with contesting such claim as the
        Employer shall reasonably request in writing from time to time,
        including, without limitation, accepting legal representation with
        respect to such claim by an attorney reasonably selected by the
        Employer;

           (3) cooperate with the Employer in good faith in order effectively to
        contest such claim; and

           (4) permit the Employer to participate in any proceedings relating to
        such claim;

Page 9                                         MetaSolv Confidential Information

<PAGE>

provided, however, that the Employer shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Executive harmless, on an
after-tax basis, for any excise tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses. Without limitation on the foregoing provision of
this Paragraph 9D, the Employer shall control all proceedings taken in
connection with such contest and, at its sole option, may pursue or forego any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct the Executive to pay the tax claimed and sue for a refund or contest the
claim in any permissible manner, and the Executive agrees to prosecute such
contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Employer shall
determine. Notwithstanding anything herein to the contrary, if, after the
receipt by the Executive of an amount advanced by the Employer pursuant to this
Paragraph 9D, the Executive becomes entitled to receive any refund with respect
to such claim, the Executive shall (subject to the Employer's substantial
compliance with the requirements of this Paragraph 9D) promptly pay to the
Employer the amount of such refund plus interest at an annual rate equal to the
Applicable Federal Rate provided for in Section 1274(d) of the Code from the
date the Gross-Up Payment was paid to the Executive until the date of the
repayment to the Employer.

     10. Protective Covenants. The Executive acknowledges and agrees that solely
by virtue of his employment by, and relationship with, the Employer, he has
acquired and will acquire "Confidential Information," as hereinafter defined, as
well as special knowledge of the Employer's relationships with its customers,
and that, but for his association with the Employer, the Executive would not or
will not have had access to said Confidential Information or knowledge of said
relationships. The Executive further acknowledges and agrees (i) that the
Employer has long term, near-permanent relationships with its customers, and
that those relationships were developed at great expense and difficulty to the
Employer over several years of close and continuing involvement; (ii) that the
Employer's relationships and goodwill with its customers are and will continue
to be valuable, special and unique assets of the Employer; and (iii) that the
Employer has the following protectable interests that are critical to its
competitive advantage in the industry and would be of demonstrable value in the
hands of a competitor: pricing models, formulas, software applications and
designs and other technologies and devices utilized in the management of
communications. In return for the consideration described in this Agreement, and
other good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, and as a condition precedent to the Employer entering into
this Agreement, and as an inducement to the Employer to do so, the Executive
hereby represents, warrants, and covenants as follows:

         A. The Executive has executed and delivered this Agreement as his free
and voluntary act, after having determined that the provisions contained herein
are of a material benefit to him, and that the duties and obligations imposed on
him hereunder are fair and reasonable and will not prevent him from earning a
comparable livelihood following the termination of his employment with the
Employer.

<PAGE>

         B. The Executive has read and fully understands the terms and
conditions set forth herein, has had time to reflect on and consider the
benefits and consequences of entering into this Agreement, and has had the
opportunity to review the terms hereof with an attorney or other representative,
if he so chooses.

         C. The execution and delivery of this Agreement by the Executive does
not conflict with, or result in a breach of or constitute a default under, any
agreement or contract, whether oral or written, to which the Executive is a
party or by which the Executive may be bound. In addition, the Executive has
informed the Employer of, and provided the Employer with copies of, any
non-competition, confidentiality, work-for-hire or similar agreements to which
the Executive is subject or may be bound.

         D. The Executive agrees that, if Executive ceases to be employed by
Employer for any reason, including without limitation the non-renewal of this
Agreement by the Company, the Executive will not, for a period of two years ,
except on behalf of the Employer, anywhere in the United States of America or in
any other place or venue where the Employer or any affiliate, subsidiary, or
division thereof now conducts or operates, or may conduct or operate, its
business prior to the date of the termination of Executive's employment:

            (1) directly or indirectly, contact, solicit or direct any person,
          firm, corporation, association or other entity to contact or solicit,
          any of the Employer's customers or prospective customers (as
          hereinafter defined) for the purpose of providing any products and/or
          services that are the same as or similar to the products and services
          provided by the Employer to its customers during the term hereof;

            (2) solicit or accept if offered to him, with or without
          solicitation, on his own behalf or on behalf of any other person, the
          services of any person who is a then current employee of the Employer
          (or was an employee of the Employer during the year preceding such
          solicitation), nor solicit any of the Employer's then current
          employees (or an individual who was employed by or engaged by the
          Employer during the year preceding such solicitation) to terminate
          employment or an engagement with the Employer, nor agree to hire any
          then current employee (or an individual who was an employee of the
          Employer during the year preceding such hire) of the Employer into
          employment with himself or any company, individual or other entity; or

            (3) directly or indirectly, whether as an investor (excluding
          investments representing less than one percent (1%) of the common
          stock of a public company), lender, owner, stockholder, officer,
          director, consultant, employee, agent, salesperson or in any other
          capacity, whether part-time or full-time, become associated with any
          business involved in the design, manufacture, marketing, or servicing
          of products then constituting ten percent (10%) or more of the annual
          revenues of the Employer; or

Page 11                                        MetaSolv Confidential Information

<PAGE>

            (4) act as a consultant, advisor, officer, manager, agent, director,
          partner, independent contractor, owner, or employee for or on behalf
          of any of the Employer's customers or prospective customers (as
          hereinafter defined), with respect to or in any way with regard to any
          aspect of the Employer's business and/or any other business activities
          in which the Employer engages during the term hereof.

          E. The Executive acknowledges and agrees that the scope described
above is necessary and reasonable in order to protect the Employer in the
conduct of its business and that, if the Executive becomes employed by another
employer, he shall be required to disclose the existence of this Paragraph 10 to
such employer and the Executive hereby consents to and the Employer is hereby
given permission to disclose the existence of this Paragraph 10 to such
employer.

          F. For purposes of this Paragraph 10, "customer" shall be defined as
any person, firm, corporation, association, or entity that purchased any type of
product and/or service from the Employer or is or was doing business with the
Employer or the Executive within the twelve (12) month period immediately
preceding termination of the Executive's employment. For purposes of this
Paragraph 10, "prospective customer" shall be defined as any person, firm,
corporation, association, or entity (i) contacted or solicited by the Executive
(whether directly or indirectly) or (ii) to the Executive's knowledge, contacted
or solicited by any other employee or representative of the Employer, or (iii)
who contacted the Executive (whether directly or indirectly) or (iv) to the
Executive's knowledge, who contacted the Employer within the twelve (12) month
period immediately preceding termination of the Executive's employment for the
purpose of having such persons, firms, corporations, associations, or entities
become a customer of the Employer.

          G. The Executive agrees that both during his employment and thereafter
the Executive will not, for any reason whatsoever, use for himself or disclose
to any person not employed by the Employer any "Confidential Information" of the
Employer acquired by the Executive during his relationship with the Employer,
both prior to and during the term of this Agreement. The Executive further
agrees to use Confidential Information solely for the purpose of performing
duties with the Employer and further agrees not to use Confidential Information
for his own private use or commercial purposes or in any way detrimental to the
Employer. The Executive agrees that Confidential Information includes but is not
limited to: (1) any financial, engineering, business, planning, operations,
services, potential services, products, potential products, technical
information and/or know-how, organization charts, formulas, business plans,
production, purchasing, marketing, pricing, sales, profit, personnel, customer,
broker, supplier, or other lists or information of the Employer; (2) any papers,
data, records, processes, methods, techniques, systems, models, samples,
devices, equipment, compilations, invoices, customer lists, or documents of the
Employer; (3) any confidential information or trade secrets of any third party
provided to the Employer in confidence or subject to other use or disclosure
restrictions or limitations; and (4) any other information, written, oral, or
electronic, whether existing now or at

Page 12                                        MetaSolv Confidential Information

<PAGE>

some time in the future, whether pertaining to current or future developments,
and whether previously accessed during the Executive's tenure with the Employer
or to be accessed during his future employment with the Employer, which pertains
to the Employer's affairs or interests or with whom or how the Employer does
business. The Employer acknowledges and agrees that Confidential Information
does not include (x) information properly in the public domain, or (y)
information in the Executive's possession prior to the date of his original
employment with the Employer, except to the extent that such information is or
has become a trade secret of the Employer or is or otherwise has become the
property of the Employer.

          H. In the event that the Executive intends to communicate information
to any individual(s), entity or entities (other than the Employer), to permit
access by any individual(s), entity or entities (other than the Employer), or to
use information for the Executive's own account or for the account of any
individual(s), entity or entities (other than the Employer) and such information
would be Confidential Information hereunder but for the exceptions set out at
(x) and (y) of Paragraph 10G of this Agreement, the Executive shall notify the
Employer of such intent in writing, including a description of such information,
no less than fifteen (15) days prior to such communication, access or use.

          I. During and after the term of employment hereunder, the Executive
will not remove from the Employer's premises any documents, records, files,
notebooks, correspondence, reports, video or audio recordings, computer
printouts, computer programs, computer software, price lists, microfilm,
drawings or other similar documents containing Confidential Information,
including copies thereof, whether prepared by him or others, except as his duty
shall require, and in such cases, will promptly return such items to the
Employer. Upon termination of his employment with the Employer, all such items
including summaries or copies thereof, then in the Executive's possession, shall
be returned to the Employer immediately.

          J. The Executive recognizes and agrees that all ideas, inventions,
patents, copyrights, copyright designs, trade secrets, trademarks, processes,
discoveries, enhancements, software, source code, catalogues, prints, business
applications, plans, writings, and other developments or improvements and all
other intellectual property and proprietary rights and any derivative work based
thereon (the "Inventions") made, conceived, or completed by the Executive, alone
or with others, during the term of his employment, whether or not during working
hours, that are within the scope of the Employer's business operations or that
relate to any of the Employer's work or projects (including any and all
inventions based wholly or in part upon ideas conceived during the Executive's
employment with the Employer), are the sole and exclusive property of the
Employer. The Executive further agrees that (1) he will promptly disclose all
Inventions to the Employer and hereby assigns to the Employer all present and
future rights he has or may have in those Inventions, including without
limitation those relating to patent, copyright, trademark or trade secrets; and
(2) all of the Inventions eligible under the copyright laws are "work made for
hire." At the request of the Employer, the Executive will do all things deemed
by the Employer to be reasonably necessary to perfect title to the Inventions in
the Employer and to assist in obtaining for the Employer such patents,
copyrights or other protection as may be provided under law and desired by the
Employer, including but not limited to executing and signing any and all
relevant applications, assignments or other instruments.

Page 13                                        MetaSolv Confidential Information

<PAGE>

Notwithstanding the foregoing, the Employer hereby notifies the Executive that
the provisions of this Paragraph 10 shall not apply to any Inventions for which
no equipment, supplies, facility or trade secret information of the Employer was
used and which were developed entirely on the Executive's own time, unless (1)
the Invention relates (i) to the business of the Employer, or (ii) to actual or
demonstrably anticipated research or development of the Employer, or (2) the
Invention results from any work performed by the Executive for the Employer.

          K. The Executive acknowledges and agrees that all customer lists,
supplier lists, and customer and supplier information, including, without
limitation, addresses and telephone numbers, are and shall remain the exclusive
property of the Employer, regardless of whether such information was developed,
purchased, acquired, or otherwise obtained by the Employer or the Executive. The
Executive also agrees to furnish to the Employer on demand at any time during
the term of this Agreement, and upon the termination of this Agreement, any
other records, notes, computer printouts, computer programs, computer software,
price lists, microfilm, or any other documents related to the Employer's
business, including originals and copies thereof. The Executive recognizes and
agrees that he has no expectation of privacy with respect to the Employer's
telecommunications, networking or information processing systems (including,
without limitation, stored computer files, email messages and voice messages)
and that the Executive's activity and any files or messages on or using any of
those systems may be monitored at any time without notice.

          L. The Executive acknowledges that he may become aware of "material"
nonpublic information relating to customers whose stock is publicly traded. The
Executive acknowledges that he is prohibited by law as well as by Employer
policy from trading in the shares of such customers while in possession of such
information or directly or indirectly disclosing such information to any other
persons so that they may trade in these shares. For purposes of this Paragraph
10L, "material" information may include any information, positive or negative,
which might be of significance to an investor in determining whether to
purchase, sell or hold the stock of publicly traded customers. Information may
be significant for this purpose even if it would not alone determine the
investor's decision. Examples include a potential business acquisition, internal
financial information that departs in any way from what the market would expect,
the acquisition or loss of a major contract, or an important financing
transaction.

          M. The Employer does not wish to incorporate any unlicensed or
unauthorized material into its products or services or those of its affiliates.
Therefore, the Executive agrees that he will not knowingly disclose to the
Employer, use in the Employer's business, or cause the Employer to use, any
information or material which is confidential or proprietary to any third party
including, but not limited to, any former employer, competitor or client, unless
the Employer has a right to receive and use such information. The Executive will
not incorporate into his work any material which is subject to the copyrights of
any third party unless the Employer has a written agreement with such third
party or otherwise has the right to receive and use such information.

          N. It is agreed that any breach or anticipated or threatened breach of
any of the Executive's covenants contained in this Paragraph 10 will result in
irreparable harm and continuing damages to the Employer and its business and
that the Employer's remedy at law for

Page 14                                        MetaSolv Confidential Information

<PAGE>

any such breach or anticipated or threatened breach will be inadequate and,
accordingly, in addition to any and all other remedies that may be available to
the Employer at law or in equity in such event, any court of competent
jurisdiction may issue a decree of specific performance or issue a temporary and
permanent injunction, without the necessity of the Employer posting bond or
furnishing other security and without proving special damages or irreparable
injury, enjoining and restricting the breach, or threatened breach, of any such
covenant, including, but not limited to, any injunction restraining the
Executive from disclosing, in whole or part, any Confidential Information. The
Executive acknowledges the truthfulness of all factual statements in this
Agreement and agrees that he is estopped from and will not make any factual
statement in any proceeding that is contrary to this Agreement or any part
thereof. The Executive further agrees to pay all of the Employer's costs and
expenses, including reasonable attorneys' and accountants' fees, incurred in
enforcing such covenants.

         O. For a period of two years following the termination of his
employment with Employer, Executive agrees that he shall not defame or disparage
the Employer's business, products or services, or its officers

     11. Liquidated Damages for Executive's Breach; Liability Limitations.

         A. Liquidated Damages. The parties acknowledge that Executive is
uniquely qualified for his employment hereunder, that Employer would be severely
disadvantaged in the event Executive left the employ of Employer prior to the
expiration of the term hereof or if the non-solicitation provisions of Paragraph
10D(2) are breached, and that Employer's damages caused by any such breach by
Executive are real and certain, but unliquidated and difficult to calculate.
Accordingly, in the event either (1) that the Executive should terminate his or
her employment with the Employer, in a manner other than as provided for under
Paragraph 8E or 8F above, or (2) that the Employer should terminate Employee's
services under Paragraph 8C above, or (3) violate the non-solicitation
provisions of Paragraph 10D(2), then both Executive and the Employer agree that
Employee shall pay to Employer on demand an amount equal to the sum of 6 months'
Base Salary, plus the amount of any Bonus Amounts paid to the Executive during
the previous six months prior to such termination, as liquidated damages
attributable specifically to the premature termination of Executive's employment
and not as a penalty.

         B. Liability Limitations. Except for damages arising from Executive's
breach of the provisions of Paragraph 10 of this Agreement (other than the
non-solicitation provisions of Paragraph 10D(2)), and except for damages arising
from Executive's breach of this Agreement that is committed knowingly,
willfully, or with gross negligence, it is agreed that: (1) Executive shall not
be liable for any indirect, exemplary, incidental or consequential damages
arising from or otherwise relating to Executive's performance or failure to
perform under this Agreement; and (2) Executive's liability to MetaSolv arising
from or otherwise relating to Executive's performance or failure to perform
under this Agreement is limited to an amount not greater than the sum of 12
months' Base Salary, plus the amount of any Bonus Amounts paid to the Executive
during the previous 12 months prior to such breach.

     12. Notices. Any and all notices required in connection with this Agreement
shall be deemed adequately given only if in writing and (a) personally
delivered, or sent by first class,

Page 15                                        MetaSolv Confidential Information

<PAGE>

registered or certified mail, postage prepaid, return receipt requested, or by
recognized overnight courier, (b) sent by facsimile, provided a hard copy is
mailed on that date to the party for whom such notices are intended, or (c) sent
by other means at least as fast and reliable as first class mail. A written
notice shall be deemed to have been given to the recipient party on the earlier
of (a) the date it shall be delivered to the address required by this Agreement;
(b) the date delivery shall have been refused at the address required by this
Agreement; (c) with respect to notices sent by mail or overnight courier, the
date as of which the Postal Service or overnight courier, as the case may be,
shall have indicated such notice to be undeliverable at the address required by
this Agreement; or (d) with respect to a facsimile, the date on which the
facsimile is sent and receipt of which is confirmed. Any and all notices
referred to in this Agreement, or which either party desires to give to the
other, shall be addressed to his residence in the case of the Executive, or to
its principal office in the case of the Employer.

     13. Waiver of Breach. A waiver by the Employer of a breach of any provision
of this Agreement by the Executive shall not operate or be construed as a waiver
or estoppel of any subsequent breach by the Executive. No waiver shall be valid
unless in writing and signed by an authorized officer of the Employer.

     14. Successors; Binding Agreement.

         A. This Agreement shall be binding upon and shall inure to the benefit
of the Employer and its Successors and Assigns, and the Employer shall require
any Successors and Assigns to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Employer would be
required to perform it if no such succession or assignment had taken place.

         B. Neither this Agreement nor any right or interest hereunder shall be
assignable or transferable by the Executive or his beneficiaries or legal
representatives, except by will or by the laws of descent and distribution, and
this Agreement shall inure to the benefit of and be enforceable by the
Executive's legal representatives.

     15. Entire Agreement. This Agreement and the Stock Option Agreements
referenced herein set forth the entire and final agreement and understanding of
the parties and contains all of the agreements made between the parties with
respect to the subject matter hereof. This Agreement supersedes any and all
other agreements, either oral or in writing, between the parties hereto, with
respect to the subject matter hereof. No change or modification of this
Agreement shall be valid unless in writing and signed by the Employer and the
Executive.

     16. Severability. If any provision of this Agreement shall be found invalid
or unenforceable for any reason, in whole or in part, then such provision shall
be deemed modified, restricted, or reformulated to the extent and in the manner
necessary to render the same valid and enforceable, or shall be deemed excised
from this Agreement, as the case may require, and this Agreement shall be
construed and enforced to the maximum extent permitted by law, as if such
provision had been originally incorporated herein as so modified, restricted, or
reformulated or as if such provision had not been originally incorporated
herein, as the case may be. The parties further agree to seek a lawful
substitute for any provision found to be unlawful; provided, that, if

Page 16                                        MetaSolv Confidential Information

<PAGE>

the parties are unable to agree upon a lawful substitute, the parties desire and
request that a court or other authority called upon to decide the enforceability
of this Agreement modify those restrictions in this Agreement that, once
modified, will result in an agreement that is enforceable to the maximum extent
permitted by the law in existence at the time of the requested enforcement.

     17. Headings. The headings in this Agreement are inserted for convenience
only and are not to be considered a construction of the provisions hereof.

     18. Execution of Agreement. This Agreement may be executed in several
counterparts, each of which shall be considered an original, but which when
taken together, shall constitute one agreement.

     19. Recitals. The recitals to this Agreement are incorporated herein as an
integral part hereof and shall be considered as substantive and not precatory
language.

     20. Arbitration. Any controversy, claim or dispute between the parties
relating to the Executive's employment or termination of employment, whether or
not the controversy, claim or dispute arises under this Agreement (other than
any controversy or claim arising under Paragraph 10), shall be resolved by
arbitration in accordance with the National Rules for the Resolution of
Employment Disputes ("Rules") of the American Arbitration Association through a
single arbitrator selected in accordance with the Rules. The decision of the
arbitrator shall be rendered within thirty (30) days of the close of the
arbitration hearing and shall include written findings of fact and conclusions
of law reflecting the appropriate substantive law. Judgment upon the award
rendered by the arbitrator may be entered in any court having jurisdiction
thereof in the State of Texas. In reaching his or her decision, the arbitrator
shall have no authority (a) to authorize or require the parties to engage in
discovery (provided, however, that the arbitrator may schedule the time by which
the parties must exchange copies of the exhibits that, and the names of the
witnesses whom, the parties intend to present at the hearing), (b) to interpret
or enforce Paragraph 10 of the Agreement (for which Paragraph 21 shall provide
the exclusive venue), (c) to change or modify any provision of this Agreement,
(d) to base any part of his or her decision on the common law principle of
constructive termination, or (e) to award punitive damages or any other damages
not measured by the prevailing party's actual damages and may not make any
ruling, finding or award that does not conform to this Agreement. Each party
shall bear all of his or its own legal fees, costs and expenses of arbitration
and one-half (1/2) of the costs of the arbitrator.

     21. Governing Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Texas, without reference to its
conflict of law provisions. Furthermore, as to Paragraph 10, the Executive
agrees and consents to submit to personal jurisdiction in the State of Texas in
any state or federal court of competent subject matter jurisdiction situated in
Collin County, Texas. The Executive further agrees that the sole and exclusive
venue for any suit arising out of, or seeking to enforce, the terms of Paragraph
10 of this Agreement shall be in a state or federal court of competent subject
matter jurisdiction situated in Collin County, Texas. In addition, the Executive
waives any right to challenge in another court any judgment entered by such
Collin County, Texas court

or to assert that any action instituted by the Employer in any such court is in
the improper venue or should be transferred to a more convenient forum.

     IN WITNESS WHEREOF, the parties have set their signatures on the date first
written above.
