                              SEVERANCE AGREEMENT

       This Agreement (the "Agreement") is made and entered into as of July 10,
2000, between MTI Technology Corporation, a corporation organized under the laws
of the State of Delaware (the "Company"), and Paul W. Emery, II (the
"Executive").

                                    RECITALS

       A. Executive is being hired to serve as an officer of the Company.

       B. The Board of Directors of the Company (the "Board") recognizes that
the possibility of a Change in Control (as hereinafter defined) exists and that
the threat or the occurrence of a Change in Control can result in significant
distractions to its key management personnel because of the uncertainties
inherent in such a situation;

       C. The Board has determined that it is essential and in the best interest
of the Company and its stockholders to obtain and retain the services of the
Executive in the event of a threat or occurrence of a Change in Control and to
ensure the Executive's continued dedication and efforts in such event without
undue concern for the Executive's personal, financial and employment security;
and

       D. In order to induce the Executive to accept employment with the
Company, particularly in the event of a threat or the occurrence of a Change in
Control, the Company desires to enter into this Agreement with the Executive to
provide the Executive with certain benefits in the event that the Executive's
employment is terminated as a result of, or in connection with, a Change in
Control.

omission was in the best interest of the Company.

       in Control;

       effect (without reduction in benefit level and/or reward opportunities)
       any material compensation or Executive benefit plan in which the
       Executive was participating at any time within ninety (90) days preceding

                            (vii) any purported termination of the Executive's
       employment for Cause by the Company which does not comply with the terms
       of Section 2.4; or

                            (viii) the failure of the Company to obtain an
       agreement, satisfactory to the Executive, from any Successors and Assigns

       3. Termination Of Employment.

              3.1. If, during the term of this Agreement, the Executive's
employment with the Company shall be terminated within twelve (12) months
following a Change in Control, the Executive shall be entitled to the following
compensation and benefits:

                     (a) If the Executive's employment with the Company shall be
terminated (1) by the Company for Cause or Disability, (2) by reason of the
Executive's death or (3) by the Executive other than for Good Reason, the
Company shall pay to the Executive the Accrued Compensation and, if such
termination is other than by the Company for Cause, the Company shall also pay

                     (b) If the Executive's employment with the Company shall be
terminated for any reason other than as specified in Section 3.1(a), the
Executive shall be entitled to the following:

                            (i) the Company shall pay the Executive all Accrued
       Compensation and a Pro Rata Bonus;

                            (ii) the Company shall pay the Executive as
       severance pay and in lieu of any further compensation for periods
       subsequent to the Termination Date, in a single payment, an amount in
       cash equal to the sum of (A) the Base Amount and (B) the Bonus Amount;
       and

                            (iii) for a number of months equal to twelve (12)
       (the "Continuation Period"), the Company shall, at its expense, continue
       on behalf of the Executive and the Executive's dependents and
       beneficiaries the life insurance, disability, medical, dental and
       hospitalization benefits provided (A) to the Executive at any time during
       the 90-day period prior to the Change in Control or at any time
       thereafter or (B) to other similarly situated executives who continue in
       the employ of the Company during the Continuation Period. The coverage
       and benefits (including deductibles and costs) provided in this Section
       3.1(b)(iii) during the Continuation Period shall be no less favorable to
       the Executive and the Executive's dependents and beneficiaries, than the
       most favorable of such coverages and benefits during any of the periods
       referred to in clauses (A) and (B) above. The Company's obligation
       hereunder with respect to the foregoing benefits shall be limited to the
       extent that the Executive obtains any such benefits pursuant to a
       subsequent employer's benefit plans, in which case the Company may reduce
       the coverage of any benefits it is required to provide the Executive
       hereunder as long as the aggregate coverages and benefits of the combined
       benefit plans are no less favorable to the Executive than the coverages
       and benefits required to be provided hereunder. This subsection (iii)
       shall not be interpreted so as to limit any benefits to which the
       Executive or the Executive's dependents or beneficiaries may be entitled
       under any of the Company's Executive benefit plans, programs or practices
       following the Executive's termination of employment, including without
       limitation, retiree medical and life insurance benefits.


                                       6
<PAGE>   7

                     (c) The amounts provided for in Sections 3.l (a) and
3.1(b)(i) and (ii) shall be paid in a single lump sum cash payment within
forty-five (45) days after the Executive's Termination Date (or earlier, if
required by applicable law).

                     (d) The Executive shall not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other employment
or otherwise, and no such payment shall be offset or reduced by the amount of
any compensation or benefits provided to the Executive in any subsequent
employment except as provided in Section 3.1(b)(iii).

              3.2. (a) The severance pay and benefits provided for in this
Section 3 shall be in lieu of any other severance or termination pay to which
the Executive may be entitled under any Company severance or termination plan,
program, practice or arrangement.

                     (b) The Executive's entitlement to any other compensation
or benefits shall be determined in accordance with the Company's Executive
benefit plans and other applicable programs, policies and practices then in
effect.

       4. Notice Of Termination. Within one (1) year following a Change in
Control, any purported termination of the Executive's employment shall be
communicated by Notice of Termination to the Executive. For purposes of this
Agreement, no such purported termination shall be effective without such Notice
of Termination.

       5. Excise Tax Limitation.

              (a) Notwithstanding anything in this Agreement to the contrary, if
any portion of any payments to Executive by the Company under this Agreement and
any other present or future plan of the Company or other present or future
agreement between Executive and the Company would not be deductible by the
Company (collectively, "Payments") for federal income tax purposes by reason of
application of Section 162(m) of the Internal Revenue Code (the "Code"), then
payment of that portion to Executive shall be deferred until the earliest date
upon which payment thereof can be made to Executive without being non-deductible
pursuant to Section 162(m) of the Code. In the event of such deferral, the
Company shall pay interest to Executive on the deferred amount at 120% of the
applicable federal rate provided for in Section 1274(d)(1) of the Code. In
addition, notwithstanding any provision of this Agreement to the contrary, the
aggregate present value of the payments and benefits (excluding those payments
and benefits not treated as parachute payments under Code Section 280G(b)) to be
made or provided to the Executive by the Company (whether pursuant to this
Agreement or otherwise) shall not exceed three times the Executive's annualized
includible compensation for the base period, as defined in Code Section 280G(d)
of the Code, minus one dollar ($1.00) (the "Limited Payment Amount"), and any
excess payments or benefits shall be forfeited; provided, however, that the
forfeiture provision of this sentence shall apply only if such forfeiture
provision results in larger aggregate after-tax payments and benefits to the
Executive than if the forfeiture provision did not apply. The intent of this
portion of this subsection 5(a) is to prevent any payment or benefit to the
Executive from being subject to the excise tax imposed by Code Section 4999 and


                                       7
<PAGE>   8

to prevent any item of expense or deduction of the Company from being disallowed
as a result of the application of Code Section 280G, but only if the after-tax
payments and benefits payable or provided to the Executive are greater after
application of the forfeiture provision than if the forfeiture provision did not
apply. The interpretation of this subsection 5(a), its application to any
occurrence or event, the determination of whether any payment or benefit would
not be treated as a parachute payment, the determination of the aggregate
present value of all payments and benefits to be made or provided to the
Executive, the determination of the value of the payments and benefits payable
or to be provided to the Executive after reduction for all applicable taxes, and
what specific payments or benefits otherwise available to the Executive shall be
limited or eliminated by operation of this subsection 5(a) shall be reasonably
made by the Company and shall be binding on all persons.

              (b) An initial determination as to whether the Payments shall be
reduced to the Limited Payment Amount and the amount of such Limited Payment
Amount shall be made, at the Company's expense, by the accounting firm that is
the Company's independent accounting firm as of the date of the Change in
Control (the "Accounting Firm"). The Accounting Firm shall provide its
determination (the "Determination"), together with detailed supporting
calculations and documentation, to the Company and the Executive within twenty
(20) days of the Termination Date if applicable, or such other time as requested
by the Company or by the Executive (provided the Executive reasonably believes
that any of the Payments may be subject to the Excise Tax), and if the
Accounting Firm determines that there is substantial authority (within the
meaning of Section 6662 of the Code) that no Excise Tax is payable by the
Executive with respect to a Payment or Payments, it shall furnish the Executive
with an opinion reasonably acceptable to the Executive that no Excise Tax will
be imposed with respect to any such Payment or Payments. Within ten (10) days of
the delivery of the Determination to the Executive, the Executive shall have the
right to dispute the Determination (the "Dispute"). If there is no Dispute, the
Determination shall be binding, final and conclusive upon the Company and the
Executive.

       6. Successors: Binding Agreement.

              (a) This Agreement shall be binding upon and shall inure to the
benefit of the Company, its Successors and Assigns and the Company 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 Company 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 the Executive's
beneficiaries or legal representatives, except by will or by the laws of descent
and distribution. This Agreement shall inure to the benefit of and be
enforceable by the Executive's legal personal representative.

       7. Confidential Information. Executive understands and acknowledges that
his work as an employee of the Company involves access to and creation of
confidential, proprietary, and trade secret information of the Company and its
affiliates, consultants, customers, clients, and


                                       8

business associates (collectively, as defined more extensively in Exhibit "A,"
"Proprietary Information"). As part of this Agreement, Executive agrees to
execute, and be bound by, the Company's "Employee/Consultant Proprietary
Information Agreement," a copy of which is attached hereto as Exhibit "A."

       8. Notice. All notices, requests, demands, and other communications
hereunder shall be in writing, and shall be delivered in person, by facsimile,
or by certified or registered mail with return receipt requested. Each such
notice, request, demand, or other communication shall be effective (a) if
delivered by hand, when delivered at the address specified in this Section; (b)

limit the Executive's continuing or future participation in any benefit, bonus,
incentive or other plan or program provided by the Company (except for any
severance or termination policies, plans, programs or practices) and for which
the Executive may qualify, nor shall anything herein limit or reduce such rights

       10. No Implied Employment Rights. Executive acknowledges and agrees that
nothing in this Agreement shall be construed to imply that his employment is
guaranteed for any period of time. Executive understands that his employment is
"at will," which means that either the Company or the Executive can terminate
the employment relationship at any time, with or without advance notice, for any
reason or no reason, with or without cause. Executive understands that the only
way that his "at will" employment relationship can be altered is by a written
agreement signed by the Executive and the President of the Company.

provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any circumstances, including, without
limitation, any set-off, counterclaim, recoupment, defense or other right which
the Company may have against an Executive or others.

       12. Miscellaneous. No provision of this Agreement may be modified, waived
or discharged, unless such waiver, modification or discharge is agreed to in
writing and signed by the Executive and the Company. No waiver by either party
hereto at any time of any breach by the other party hereto, or compliance with,
any condition or provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions or conditions at
the same or at any prior or subsequent time. No agreement or representation,
oral or otherwise, express or implied, with respect to the subject matter hereof
have been made by either party which are not expressly set forth in this
Agreement.

       13. Governing Law. This Agreement has been negotiated and executed in the
State of California and is to be performed in Orange County, California. This
Agreement shall be governed by and interpreted in accordance with the laws of
the State of California, including all matters of construction, validity,
performance, and enforcement, without giving effect to principles of conflict of
laws. Any dispute, action, litigation, or other proceeding concerning this
Agreement shall be instituted, maintained, heard, and decided in Orange County,
California.

       14. Severability. The provisions of this Agreement shall be deemed
severable and the invalidity or unenforceability of any provision shall not
affect the validity or enforceability of the other provisions hereof.

       15. Entire Agreement. This Agreement constitutes the entire agreement
between the parties hereto and supersedes all prior agreements, if any,
understandings and arrangements, oral or written, between the parties hereto
with respect to the subject matter hereof.

       16. Remedies. All rights, remedies, undertakings, obligations, options,
covenants, conditions, and agreements contained in this Agreement shall be
cumulative and no one of them shall be exclusive of any other.

       17. Interpretation. The language in all parts of this Agreement shall be
in all cases construed simply according to its fair meaning and not strictly for
or against any party. Whenever the context requires, all words used in the
singular will be construed to have been used in the plural, and vice versa. The
descriptive headings of the sections and subsections of this Agreement are
inserted for convenience only and shall not control or affect the interpretation
or construction of any of the provisions herein.

       18. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument.

cooperate in good faith with the other and to execute and deliver such further
instruments and perform such other acts as may be reasonably necessary or
appropriate to consummate and carry into effect the transactions contemplated
under this Agreement.

been given the opportunity to consult with counsel of his own choice concerning
this Agreement, and (b) that he has read and understands the Agreement, is fully
aware of its legal effect, and has entered into it freely based upon his own

              EMPLOYEE/CONSULTANT PROPRIETARY INFORMATION AGREEMENT

       In consideration of my present and future employment by MTI Technology
Corporation (together with its subsidiaries, the "Company"), I agree to the
following:

       1. Proprietary Information.

              (a) I understand and acknowledge that my work as an employee of
the Company has involved and will continue to involve access to and creation of
confidential, proprietary, and trade secret information of the Company and its
affiliates, consultants, customers, clients, and business associates
(collectively, as defined more extensively below, "Proprietary Information"). I
further understand and acknowledge that the Company and its clients have
developed, compiled, and otherwise obtained this Proprietary Information often
at great expense, and that such information has great value to their respective
businesses. I agree to hold in strict confidence and in trust for the sole
benefit of the Company and its clients all Proprietary Information. I further
agree that I shall treat all Proprietary Information as private, privileged, and
confidential, and that I shall not use, disclose, or release any Proprietary
Information in any way to any person, firm, or institution at any time, even
after termination of my employment, except to the extent necessary to carry out
my responsibilities as an Executive of the Company. I further understand and
agree that the publication of Proprietary Information through literature or
speeches must be approved in advance in writing by a duly authorized officer of
the Company.

              (b) I understand and acknowledge that, for purposes of this
Agreement, "Proprietary Information" means all confidential, proprietary, or
trade secret information and ideas in whatever form, tangible or intangible,
whether disclosed to or learned or developed by me, prior or subsequent to the
date hereof, pertaining in any manner to the business of the Company or to the
Company's affiliates, consultants, clients, or business associates, unless: (i)
the information is or becomes publicly known through lawful means; (ii) the
information was rightfully in my possession or part of my general knowledge
prior to my employment by the Company; or (iii) the information is disclosed to
me without confidential or proprietary restriction by a third party who
rightfully possesses the information (without confidential or proprietary
restriction) and did not learn of it, directly or indirectly, from the Company.

              (c) Without limiting the generality of the foregoing, I understand
and acknowledge that "Proprietary Information" includes all: (i) inventions,
computer codes, computer programs, formulas, schematics, techniques, algorithms,
employee suggestions, development tools and processes, computer printouts,
design drawings and manuals, and improvements or modification to any of the
foregoing; (ii) information about costs, profits, markets, and sales; (iii)
plans for future development and new product concepts; and (iv) all documents,
books, papers, drawings, models, sketches, and other data of any kind and
description, including electronic data recorded or retrieved by any means, that
have been or will be given to me by the Company (or any present or future
affiliates, consultants, customers, clients, and business associates of the
Company), as well as written or verbal instructions or comments.


                                      A-2
<PAGE>   15

       2. Use Of Proprietary Information.

       I agree that I will maintain at my work station or in other places under
my control only such Proprietary Information that I have a current "need to
know," and that I will return to the appropriate person or location, or
otherwise dispose of, Proprietary Information once my need to know no longer
exists. I agree that I will not make copies of information unless I have a
legitimate need for such copies in connection with my work.

       3. Third-Party Information.

       I recognize that the Company has received and in the future will receive
from third parties their confidential or proprietary information subject to a
duty on the Company's part to maintain the confidentiality of such information
and to use it only for certain limited purposes. I agree that I owe the Company
and such third parties, during the term of my employment and thereafter, a duty
to hold all such confidential or proprietary information in the strictest
confidence and not to disclose it to any person, firm, or corporation (except as
necessary in carrying out my work for the Company consistent with the Company's
agreement with such third party) or to use it for the benefit of anyone other
than for the Company or such third party (consistent with the Company's
agreement with such third party) without the express written authorization of a
duly authorized officer of the Company.

       4. Inventions.

              (a) Subject to Section 9 below, I hereby assign to the Company,
without additional consideration, all right, title and interest (throughout the
United States and in all foreign countries) in all ideas, processes, inventions,
technology, writings, computer programs, designs, formulas, discoveries,
patents, copyrights, trademarks, service marks, original works of authorship,
any claims or rights, and any improvements or modifications to the foregoing
(collectively, "Inventions"), whether or not subject to patent or copyright
protection, relating to any activities of the Company that have been or will be
conceived, developed, or reduced to practice by me alone or with others (i)
during the term of my employment, whether or not conceived or developed during
regular business hours, and whether or not conceived before, on, or after the
date hereof or (ii) if based on Proprietary Information, after termination of my
employment. Such Inventions shall be the sole property of the Company and, to
the maximum extent permitted by applicable law, shall be deemed works made for
hire.

              (b) I will, whether during or after my employment by the Company,
execute such written instruments and do other such acts as may be necessary in
the opinion of the Company to obtain a patent, register a copyright, or
otherwise enforce the Company's rights in such Inventions (and I hereby
irrevocably appoint the Company and any of its officers as my attorney in fact
to undertake such acts in my name).

              (c) I understand that the assignment by me to the Company does not
apply to Inventions that qualify fully under Section 2870(a) of the California
Labor Code, which is set forth on Schedule "A." I understand that nothing in
this Agreement is intended to expand the scope of protection provided by
Sections 2870 through 2872 of the California Labor Code. Except as disclosed in
Schedule "B", there are no ideas, inventions, technology, computer


                                      A-3
<PAGE>   16

programs, processes, trademarks, service marks, original works of authorship,
designs, formulas, discoveries, patents, copyrights, any claims or rights, and
any improvements or modifications to the foregoing that I wish to exclude from
the operation of this Agreement.

              (d) To the best of my knowledge, there is no existing contract in
conflict with this Agreement or any other contract in existence between me and
any other person or entity to assign ideas, inventions, technology, computer
programs, processes, trademarks, service marks, original works of authorship,
designs, formulas, discoveries, patents, copyrights, any claims or rights, and
any improvements or modifications to the foregoing.

       5. Termination of Employment.

              (a) I hereby acknowledge and agree that nothing in this Agreement
shall be construed to imply that the term of my employment is of any definite
duration. I further acknowledge and agree that I am employed on an "at-will"
basis, which means that I may quit at any time with or without cause, and the
Company may terminate my employment at any time with or without cause.

              (b) I acknowledge that, because of my responsibilities at the
Company, I have helped and will continue to help to develop and have been and
will be exposed to the Company's research and development, products, business
strategies, information on customers and clients, and other valuable Proprietary
Information, and that use or disclosure of such Proprietary Information in
breach of this Agreement would be extremely difficult to detect or prove. I also
acknowledge that the Company's relationships with its employees, affiliates,
consultants, customers, clients, business associates, and other persons are
valuable business assets. To forestall any use or disclosure of Proprietary
Information in breach of this Agreement, I agree that for the term of this
Agreement and for a period of one (1) year after termination of my employment
with the Company, I shall not, for myself or any third party, directly or
indirectly:

                     (i) divert or attempt to divert from the Company any
       business of any kind in which it is engaged, including, without
       limitation, the solicitation of or interference with any of its suppliers
       or customer; or

                     (ii) employ, solicit for employment, or recommend for
       employment any person employed by the Company.

       Furthermore, I agree that during the period of my employment with the
Company I shall not engage in any business activity that is or may be
competitive with the Company. I understand that none of my activities will be
prohibited under this section if I can prove that the action was taken without
the use in any way of Proprietary Information.

              (c) I acknowledge that, because of the difficulty of establishing
when any invention is first conceived or developed by me, or whether it results
from access to Proprietary information or the Company's equipment, facilities,
and data, I agree that any ideas, inventions, technology, computer programs,
processes, trademarks, service marks, original works of authorship, designs,
formulas, discoveries, patents, copyrights, any claims or rights, and any
improvements or modifications to the foregoing shall be presumed to be an
Invention if


                                      A-4
<PAGE>   17

conceived, developed, used, sold, exploited, or reduced to practice by me or
with my aid within one (1) year after my termination of employment with the
Company. I can rebut the above presumption if I prove that the invention, idea,
process, etc., is not an Invention as defined in paragraph 4(a).

              (d) I hereby acknowledge and agree that all personal property
including, without limitation, all books, manuals, records, models, drawings,
reports, notes, contracts, lists, files, computer software, computer tapes or
disks, blueprints, and other documents or materials (or copies thereof),
Proprietary Information, and equipment furnished to or prepared by me in the
course of or incident to my employment, belong to the Company and shall be
promptly returned to the Company once my employment with the Company is
terminated, for any reason. I will not retain any written or other tangible
information pertaining to any Invention. In the event of the termination of my
employment, I agree to sign and deliver the Termination Certificate attached as
Schedule "C" to this Agreement.

              (e) I understand that my obligations contained in this Agreement
will survive the termination of my employment with the Company, and that I will
continue to make all disclosures required of me by Paragraph 6.

       6. Disclosure.

       I agree to maintain adequate and current written records on the
development of all Inventions and to disclose promptly to the Company all
Inventions and relevant records, which records will remain the sole property of
the Company. I further agree that all information and records pertaining to any
Inventions conceived, developed, or reduced to practice by me (alone or with
others) during my period of employment or during the one-year period following
termination of my employment, shall be promptly disclosed to the Company (any
such disclosures made after the termination of my employment shall be received
by the Company in confidence for the purpose of determining if they have been
based on any Proprietary Information). The Company shall examine such
information to determine if in fact such information are Inventions subject to
this Agreement.

       7. Former or Conflicting Agreements.

       During my employment with the Company, I will not disclose to the
Company, or use, or induce the Company to use, any confidential, proprietary, or
trade secret information of others. I represent and warrant that I have returned
all property and confidential, proprietary and trade secret information
belonging to all prior employers, if any. I further represent and warrant that
my performance of the terms of this Agreement will not breach any agreement to
keep in confidence confidential proprietary and trade secret information
acquired by me in confidence or in trust prior to my employment by the Company.
I have not entered into, and I agree I will not enter into, any oral or written
agreement in conflict herewith.

       8. Information on Company Premises.

       I acknowledge that all information generated, received, or maintained by
or for me on the premises or equipment of the Company (including, without
limitation, computer systems and


                                      A-5
<PAGE>   18

electronic-mail or voicemail systems) is the property of the Company, and I
hereby waive any property or privacy rights that I may have with respect to such
information.

       9. Reserved Inventions.

       To avoid future confusion, I have listed on Schedule "B" a description of
all Inventions, if any, developed or conceived by me in which I claim any
ownership or other right. I understand that, by not listing an Invention, I am
acknowledging that the Invention was not developed or conceived before
commencement of my employment.

       10. Choice of Law.

       The validity, interpretation, enforceability, and performance of this
Agreement shall be governed by and construed in accordance with the laws of the
State of California without giving effect to its conflict of law rules. Any
dispute, action, litigation, or other proceeding concerning this Agreement shall
be instituted, maintained, heard, and decided in Orange County, California.

       11. Remedies.

       I recognize that nothing in this Agreement is intended to limit any
remedy of the Company under the California Uniform Trade Secrets Act and that I
could face possible criminal and civil actions, resulting in imprisonment and
substantial monetary liability, if I misappropriate the Company's or its
clients' trade secrets. In addition, I recognize that my violation of this
Agreement could cause the Company irreparable harm and significant injury, the
amount of which may be extremely difficult to estimate, thus, making any remedy
at law or in damages inadequate. Therefore, I agree that, in the event of a
breach or threatened breach that involves Proprietary Information of the Company
or its clients, the Company shall have the right to apply to any court of
competent jurisdiction for an order restraining any breach or threatened breach
of this Agreement and for any other relief the Company deems appropriate. This
right shall be in addition to any other remedy available to the Company in law
or equity.

       12. Successors and Assigns.

              (a) I understand and agree that the Company may assign to another
       person or entity any of its rights under this Agreement.

              (b) I further understand and agree that this Agreement shall be
       binding upon me and my heirs, executors, administrators, and successors,
       and shall inure to the benefit of the Company's successors and assigns.

       13. Severability.

       If any provision of this Agreement is determined to be invalid, illegal
or unenforceable, the validity or enforceability of the other provisions shall
not be affected.


                                      A-6
<PAGE>   19

       14. Entire Agreement.

       The terms of this Agreement are the final expression of my agreement with
respect to the subject matter hereof and may not be contradicted by evidence of
any prior or contemporaneous agreement. This Agreement shall constitute the
complete and exclusive statement of its terms and no extrinsic evidence
whatsoever may be introduced in any judicial, administrative, or other legal
proceeding involving this Agreement. No modification or amendment of this
Agreement shall be binding unless executed in writing by me and a duly
authorized officer of the Company.

I HAVE READ THIS AGREEMENT CAREFULLY AND UNDERSTAND ITS TERMS. I HAVE COMPLETELY
NOTED ON SCHEDULE "B" TO THIS AGREEMENT ANY PROPRIETARY INFORMATION, IDEAS,
PROCESSES, CREATIONS, TECHNOLOGY, INVENTIONS, PATENTS, COPYRIGHTS, OR
TRADEMARKS, WRITINGS, PROGRAMS, DESIGNS, FORMULAS, DISCOVERIES, OR IMPROVEMENTS,
RIGHTS, OR CLAIMS RELATING TO THE FOREGOING, THAT I DESIRE TO EXCLUDE FROM THIS
AGREEMENT.

       This Agreement is made and entered into as of September 2, 2000.
