         A. Executive is currently serving as an officer of the Company.

         B. The Board of Directors of the Company (the "Board") recognizes 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 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 remain in the employ of 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.

            least equal (in terms of benefit levels and/or reward opportunities)
            to those provided for under each other Executive 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;

                     (v) the insolvency or the filing (by any party, including
            the Company) of a petition for bankruptcy of the Company, which
            petition is not dismissed within sixty (60) days;

                     (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 to
            assume and agree to perform this Agreement, as contemplated in
            Section 6 hereof.

                 (b) The Executive's right to terminate the Executive's

            2.9. Notice Of Termination. For purposes of this Agreement,
following a Change in Control, "Notice of Termination" shall mean a written
notice of termination of the Executive's employment from the Company, which

<PAGE>   6

and, if such termination is other than by the Company for Cause, the Company
shall also pay the Executive a Pro Rata Bonus.

                 (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

                     (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.

                 (c) The amounts provided for in Sections 3.1(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).



                                       6
<PAGE>   7

            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. 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. Exercise 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 28OG(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
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



                                       7

<PAGE>   8
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. The Company and Executive acknowledge that
Executive, in performing the terms and conditions of Executive's employment, has
and will continue to directly or indirectly gain access to information about
Company and its operations, including, but not limited to, its modes and methods
of conducting its business and producing and marketing its products, its
employee, customer, vendor and referral source lists, its trade secrets, its
copyrighted and non-copyrighted or non-protected computer software programs, its
techniques of operation, its financial structure, and its weakness, if any. 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

              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

         1. 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.

         2. 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.

         3. 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.


         1. 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.

         1. 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.

         2. 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.

         3. 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.

         4. 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.

         12. 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

         13. 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 July 15, 1998.

                     California Labor Code Section 2870(a)



         Any provision in an employment agreement which provides that an
employee shall assign, or offer to assign, any of his or her rights in an
Invention to his or her employer shall not apply to an invention that the
employee developed entirely on his or her own time without using the employer's
