                           CHANGE OF CONTROL AGREEMENT

      This Agreement (the "Agreement") is made and entered into as of March 22,
2004 (the "Effective Date"), between MTI Technology Corporation, a corporation
organized under the laws of the State of Delaware (the "Company"), and Todd
Williams (the "Employee").

                                    RECITALS

Director of 404 Compliance.

      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 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 Employee in the event of a threat or occurrence of a Change in Control
and to ensure the Employee's continued dedication and efforts in such event
without undue concern for the Employee's personal, financial and employment
security; and

      D.    In order to induce the Employee to remain employed 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 Employee to provide
the Employee with certain benefits in the event that the Employee's employment
is terminated as a result of, or in connection with, a Change in Control.

      3.    Termination Of Employment.

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

Employee's death or (3) by the Employee other than for Good Reason, the Company
shall pay to the Employee the Accrued Compensation and, if such termination is

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

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

                        (ii)  the Company shall pay the Employee as severance
      pay and in lieu of any further compensation for periods subsequent to the

<PAGE>

                        (iii) for a number of months equal to twelve (12) (the
      "Continuation Period"), the Company shall, at its expense, continue on
      behalf of the Employee and the Employee's dependents and beneficiaries the
      life insurance, disability, medical, dental and hospitalization benefits
      provided (A) to the Employee 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 employees 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 Employee and the Employee'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 Employee 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 Employee hereunder as long as the aggregate coverages and benefits of
      the combined benefit plans are no less favorable to the Employee 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
      Employee or the Employee's dependents or beneficiaries may be entitled
      under any of the Company's Employee benefit plans, programs or practices
      following the Employee'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 Employee's Termination Date (or earlier, if
required by applicable law).

                  (d)   The Employee 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 Employee 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 Employee may be entitled under any Company severance or termination plan,
program, practice or arrangement.

                  (b)   The Employee's entitlement to any other compensation or
benefits shall be determined in accordance with the Company's employee 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 Employee's employment shall be
communicated by Notice of Termination to the Employee. For purposes of this
Agreement, no such purported termination shall be effective without such Notice
of Termination.

                                       6

      5.    Excise Tax Limitation.

            (a)   Notwithstanding anything contained in this Agreement, in the
event that any payment, benefit or distribution (within the meaning of Section
280G(b)(2) of the Internal Revenue Code of 1986, as amended (the "Code")), to
the Employee or for the Employee's benefit paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise in connection
with, or arising out of, the Employee's employment with the Company or a Change
in Control (a "Payment" or "Payments") would be subject to the excise tax
imposed by Section 4999 of the Code (the "Excise Tax"), the Payments shall be
reduced (but not below zero) if and to the extent necessary so that no Payment
to be made or benefit to be provided to the Employee shall be subject to the
Excise Tax (such reduced Payments being hereinafter referred to as the "Limited
Payment Amount"). Unless the Employee shall have given prior written notice
specifying a different order to the Company to effectuate the Limited Payment
Amount, the Company shall reduce or eliminate the Payments by first reducing or
eliminating cash payments and then by reducing those payments or benefits which
are not payable in cash, in each case in reverse order beginning with payments
or benefits which are to be paid the farthest in time from the Determination (as
hereinafter defined). Any notice given by the Employee pursuant to the preceding
sentence shall take precedence over the provisions of any other plan,
arrangement or agreement governing the Employee's rights and entitlements to any
benefits or compensation.

            (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 Employee within twenty
(20) days of the Termination Date if applicable, or such other time as requested
by the Company or by the Employee (provided the Employee 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
Employee with respect to a Payment or Payments, it shall furnish the Employee
with an opinion reasonably acceptable to the Employee 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 Employee, the Employee 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
Employee subject to the application of Section 6(c) below.

            (c)   As a result of the uncertainty in the application of Sections
4999 and 280G of the Code, it is possible that the Payments to be made to, or
provided for the benefit of, the Employee either will be greater (an "Excess
Payment") or less (an "Underpayment") than the amounts provided for by the
limitations contained in Section 6(a). If it is established pursuant to a final
determination of a court or an Internal Revenue Service (the "IRS") proceeding
which has been finally and conclusively resolved that an Excess Payment has been
made, such Excess Payment shall be deemed for all purposes to be a loan to the
Employee made on the date the Employee received the Excess Payment and the
Employee shall repay the Excess Payment to the

                                       7
<PAGE>

Company on demand (but not less than ten (10) days after written notice is
received by the Employee) together with interest on the Excess Payment at the
"Applicable Federal Rate" (as defined in Section 1274(d) of the Code) from the
date of the Employee's receipt of such Excess Payment until the date of such
repayment. In the event that it is determined by (i) the Accounting Firm, the
Company (which shall include the position taken by the Company, or together with
its consolidated group, on its federal income tax return) or the IRS, (ii)
pursuant to a determination by a court, or (iii) upon the resolution to the
Employee's satisfaction of the Dispute that an Underpayment has occurred, the
Company shall pay an amount equal to the Underpayment to the Employee within ten
(10) days of such determination or resolution, together with interest on such
amount at the Applicable Federal Rate from the date such amount would have been
paid to the Employee until the date of payment.

      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 Employee or the Employee'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 Employee's legal personal representative.

      7.    Confidential Information. Employee 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 business associates
(collectively, as defined more extensively in Exhibit "A," "Proprietary
Information"). Employee acknowledges that he executed a Proprietary Information
Agreement on June 16,1998, to protect Proprietary Information and that he shall
continue to be bound by the Proprietary Information Agreement. A copy of the
Proprietary Information Agreement is attached to this Agreement 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)
if given by facsimile, when such facsimile is transmitted to the telefacsimile
number specified in this Section and confirmation is received; or (c) if given
by certified or registered mail, three days after the mailing thereof. Notices
shall be delivered as follows: '

      9.    Non-Exclusivity Of Rights. Nothing in this Agreement shall prevent
or limit the Employee'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 Employee may qualify, nor shall anything herein limit or reduce such
rights as the Employee may have under any other agreements with the Company

program, except as explicitly modified by this Agreement.

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

to make payments provided for in this Agreement and otherwise to perform its
obligations hereunder shall be reduced by any amounts owed by Employee to the
Company including, without limitation, any set-off, counterclaim, recoupment,
defense or other right which the Company may have against Employee or others.

waived or discharged, unless such waiver, modification or discharge is agreed to

                            INDEMNIFICATION AGREEMENT

      This INDEMNIFICATION AGREEMENT (the "Agreement") is made and entered into
as of_______, 2001 (the "Effective Date") by and between MTI Technology
Corporation, a Delaware corporation (the "Company"), and Ralph Yarro (the
"Indemnitee").

      WHEREAS, it is essential to the Company to retain and attract as directors
the most capable persons available;

      WHEREAS, Indemnitee is a director of the Company;

      WHEREAS, both the Company and Indemnitee recognize the increased risk of
litigation and other claims being asserted against directors of public companies
in today's environment; and

      WHEREAS, the Company's Bylaws (the "Bylaws") require the Company to
indemnify and advance expenses to its officers to the fullest extent permitted
by law, and the Indemnitee has agreed to serve as a director of the Company in
part in reliance on the Bylaws;

      WHEREAS, in recognition of Indemnitee's need for (i) substantial
protection against personal liability based on Indemnitee's reliance on the
Bylaws, (ii) specific contractual assurance that the protection promised by the
Bylaws will be available to Indemnitee, regardless of, among other things, any
amendment to or revocation of the Bylaws or any change in the composition of the
Company's Board of Directors or acquisition transaction relating to the Company,
and (iii) an inducement to provide effective services to the Company as a
director thereof, the Company wishes to provide for the indemnification of
Indemnitee and to advance expenses to Indemnitee to the fullest extent permitted
by law and as set forth in this Agreement, and, to the extent insurance is
maintained, to provide for the continued coverage of Indemnitee under the
Company's directors' and officers' liability insurance policies.

      NOW, THEREFORE, in consideration of the premises contained herein and of
Indemnitee continuing to serve the Company directly or, at its request, with
another enterprise, and intending to be legally bound hereby, the parties hereto
agree as follows:

      2.    AGREEMENT TO INDEMNIFY.

            (a)   In the event Indemnitee was, is or becomes a party to or
witness or other participant in, or is threatened to be made a party to or
witness or other participant in, a Proceeding by reason of (or arising in part
out of) an Indemnifiable Event, the Company shall indemnify Indemnitee to the
fullest extent permitted by law, as soon as practicable but in any event no
later than thirty (30) days after written demand is presented to the Company,
against any and all Expenses, judgments, fines, penalties and amounts paid in
settlement (including all interest, assessments and other charges paid or
payable in connection with or in respect of such Expenses, judgments, fines,
penalties or amounts paid in settlement) of such Proceeding and any federal,
state, local or foreign taxes imposed on the Indemnitee as a result of the
actual or deemed receipt of any payments under this Agreement, including the
creation of the Trust pursuant to Section 4 hereof. Notwithstanding anything in
this Agreement to the contrary and except as provided in Section 5, Indemnitee
shall not be entitled to indemnification pursuant to this Agreement in
connection with any Proceeding initiated by Indemnitee against the Company or

Ralph Yarro Indemnification

                                       3
<PAGE>

any director or officer of the Company unless the Company has joined in or
consented to the initiation of such Proceeding. If so requested by Indemnitee,
the Company shall advance, within ten (10) business days of such request, any
and all Expenses to Indemnitee (an "Expense Advance"); provided, however, that
such Expenses shall be advanced only upon delivery to the Company of an
undertaking by or on behalf of the Indemnitee to repay such amount if it is
ultimately determined that Indemnitee is not entitled to be indemnified by the
Company.

            (b)   Notwithstanding the foregoing, (i) the obligations of the
Company under Section 2(a) shall be subject to the condition that the Reviewing
Party shall not have determined (in a written opinion, in any case in which the
special, independent counsel referred to in Section 3 hereof is involved) that
Indemnitee would not be permitted to be indemnified under applicable law, and
(ii) the obligation of the Company to make an Expense Advance pursuant to
Section 2(a) shall be subject to the condition that, if, when and to the extent
that the Reviewing Party determines that Indemnitee would not be permitted to be
so indemnified under applicable law, the Company shall be entitled to be
reimbursed by Indemnitee (who hereby agrees to reimburse the Company) for all
such amounts theretofore paid; provided, however, that if Indemnitee has
commenced legal proceedings in a court of competent jurisdiction to secure a
determination that Indemnitee should be indemnified under applicable law, any
determination made by the Reviewing Party that Indemnitee would not be permitted
to be indemnified under applicable law shall not be binding and Indemnitee shall
not be required to reimburse the Company for any Expense Advance until a final
judicial determination is made with respect thereto (as to which all rights of
appeal therefrom have been exhausted or have lapsed). Indemnitee's obligation to
reimburse the Company for Expense Advances shall be unsecured and no interest
shall be charged thereon. If there has not been a Change in Control, the
Reviewing Party shall be selected by the Board of Directors, and if there has
been such a Change in Control, other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control, the Reviewing Party shall be the
special, independent counsel referred to in Section 3 hereof. If there has been
no determination by the Reviewing Party or if the Reviewing Party determines
that Indemnitee substantively would not be permitted to be indemnified in whole
or in part under applicable law, Indemnitee shall have the right to commence
litigation in any court in the States of California or Delaware having subject
matter jurisdiction thereof and in which venue is proper seeking an initial
determination by the court or challenging any such determination by the
Reviewing Party or any aspect thereof, and the Company hereby consents to
service of process and to appear in any such proceeding. Any determination by
the Reviewing Party otherwise shall be conclusive and binding on the Company and
Indemnitee.

      3.    CHANGE IN CONTROL. The Company agrees that if there is a Change in
Control of the Company, other than a Change in Control which has been approved
by a majority of the Company's Board of Directors who were directors immediately
prior to such Change in Control, then with respect to all matters thereafter
arising concerning the rights of Indemnitee to indemnity payments and Expense
Advances under this Agreement or any other agreement or under applicable law or
the Company's Certificate of Incorporation or Bylaws now or hereafter in effect
relating to indemnification for Indemnifiable Events, the Company shall seek
legal advice only from special, independent counsel selected by Indemnitee and
approved by the Company, which approval shall not be unreasonably withheld. Such
special, independent

Ralph Yarro Indemnification

                                       4
<PAGE>

counsel shall not have otherwise performed services for the Company or the
Indemnitee, other than in connection with such matters, within the last five (5)
years. Such independent counsel shall not include any person who, under the
applicable standards of professional conduct then prevailing, would have a
conflict of interest in representing either the Company or Indemnitee in an
action to determine Indemnitee's rights under this Agreement. Such counsel,
among other things, shall render its written opinion to the Company and
Indemnitee as to whether and to what extent the Indemnitee would be permitted to
be indemnified under applicable law. The Company agrees to pay the reasonable
fees of the special, independent counsel referred to above and to indemnify
fully such counsel against any and all expenses (including attorneys' fees),
claims, liabilities and damages arising out of or relating to this Agreement or
the engagement of special, independent counsel pursuant hereto.

      4.    ESTABLISHMENT OF TRUST. In the event of a Potential Change in
Control, the Company shall, upon written request by Indemnitee, create a trust
for the benefit of the Indemnitee (the "Trust") and from time to time upon
written request of Indemnitee shall fund such Trust in an amount sufficient to
satisfy any and all Expenses reasonably anticipated at the time of each such
request to be incurred in connection with investigating, preparing for and
defending any Proceeding relating to an Indemnifiable Event, and any and all
judgments, fines, penalties and settlement amounts of any and all Proceedings
relating to an Indemnifiable Event from time to time actually paid or claimed,
reasonably anticipated or proposed to be paid. The amount or amounts to be
deposited in the Trust pursuant to the foregoing funding obligation shall be
determined by the Reviewing Party, in any case in which the special, independent
counsel referred to above is involved. The terms of the Trust shall provide that
upon a Change in Control (i) the Trust shall not be revoked or the principal
thereof invaded, without the written consent of the Indemnitee, (ii) the trustee
shall advance, within ten (10) business days of a request by the Indemnitee,
upon Indemnitee's having made the undertaking required under Section 2(a)
hereof, any and all Expenses to the Indemnitee (and the Indemnitee hereby agrees
to reimburse the Trust under the circumstances under which the Indemnitee would
be required to reimburse the Company under Section 2(b) of this Agreement),
(iii) the Trust shall continue to be funded by the Company in accordance with
the funding obligation set forth above, (iv) the trustee shall promptly pay to
the Indemnitee all amounts for which the Indemnitee shall be entitled to
indemnification pursuant to this Agreement or otherwise, and (v) all unexpended
funds in such Trust shall revert to the Company upon a final determination by
the Reviewing Party or a court of competent jurisdiction, as the case may be,
that the Indemnitee has been fully indemnified under the terms of this
Agreement. The trustee shall be chosen by the Indemnitee. Nothing in this
Section 4 shall relieve the Company of any of its obligations under this
Agreement. All income earned on the assets held in the Trust shall be reported
as income by the Company for federal, state, local and foreign tax purposes.

      5.    INDEMNIFICATION FOR EXPENSES INCURRED IN ENFORCING THIS AGREEMENT.
The Company shall indemnify Indemnitee against any and all expenses (including
attorneys' fees), and, if requested by Indemnitee, shall, within ten (10)
business days of such request, advance such expenses to Indemnitee, which are
incurred by Indemnitee in connection with any claim asserted against or action
brought by Indemnitee for (i) indemnification or advance payment of Expenses by
the Company under this Agreement or any other agreement or relating to
indemnification for Indemnifiable Events and/or (ii) recovery under any
directors' and officers'

Ralph Yarro Indemnification

                                       5
<PAGE>

liability insurance policies maintained by the Company, regardless of whether
Indemnitee ultimately is determined to be entitled to such indemnification,
advance expense payment or insurance recovery, as the case may be. Expenses
shall be advanced, however, only upon delivery to the Company of an undertaking
by or on behalf of the Indemnitee to repay such amount if it is ultimately
determined that Indemnitee is not entitled to be indemnified by the Company.

      6.    PARTIAL INDEMNITY. If Indemnitee is entitled under any provision of
this Agreement to indemnification by the Company for some or a portion of the
Expenses, judgments, fines, penalties and amounts paid in settlement of a
Proceeding but not, however, for all of the total amount thereof, the Company
shall nevertheless indemnify Indemnitee for the portion thereof to which
Indemnitee is entitled. Moreover, notwithstanding any other provision of this
Agreement, to the extent that Indemnitee has been successful on the merits or
otherwise in defense of any or all Proceedings relating in whole or in part to
an Indemnifiable Event or in defense of any issue or matter therein, including
dismissal without prejudice, Indemnitee shall be indemnified against all
Expenses incurred in connection therewith.

      7.    DEFENSE TO INDEMNIFICATION, BURDEN OF PROOF AND PRESUMPTIONS. It
shall be a defense to any action brought by the Indemnitee against the Company
to enforce this Agreement (other than an action brought to enforce a claim for
expenses incurred in defending a Proceeding in advance of its final disposition
where the required undertaking has been tendered to the Company) that the
Indemnitee has not met the standards of conduct that make it permissible under
the Delaware General Corporation Law for the Company to indemnify the Indemnitee
for the amount claimed. In connection with any determination by the Reviewing
Party or otherwise as to whether the Indemnitee is entitled to be indemnified
hereunder, the burden of proving such right to indemnification shall be on the
Indemnitee. Neither the failure of the Company (including its Board of
Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such action by the Indemnitee that
indemnification of the claimant is proper under the circumstances because he has
met the applicable standard of conduct set forth in the Delaware General
Corporation Law, nor an actual determination by the Company (including its Board
of Directors, independent legal counsel, or its stockholders) that the
Indemnitee had not met such applicable standard of conduct, shall be a defense
to the action or create a presumption that the Indemnitee has not met the
applicable standard of conduct. For purposes of this Agreement, the termination
of any claim, action, suit or proceeding, by judgment, order, settlement
(whether with or without court approval) or conviction, or upon a plea of nolo
contendere, or its equivalent, shall not create a presumption that Indemnitee
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law.

      8.    NON-EXCLUSIVITY. The rights of the Indemnitee hereunder shall be in
addition to any other rights Indemnitee may have under the Company's Certificate
of Incorporation or Bylaws or the Delaware General Corporation Law or otherwise;
provided, however, that this Agreement shall supersede any prior indemnification
by agreement between the Company and the Indemnitee. To the extent that a change
in the Delaware General Corporation Law (whether by statute or judicial
decision) permits greater indemnification by agreement than would be afforded
currently under the Company's Certificate of Incorporation and Bylaws and this

Ralph Yarro Indemnification

                                       6
<PAGE>

Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by
this Agreement the greater benefits so afforded by such change.

      9.    LIABILITY INSURANCE. To the extent the Company maintains an
insurance policy or policies providing directors' and officers' liability
insurance, Indemnitee shall be covered by such policy or policies, in accordance
with its or their terms, to the maximum extent of the coverage available for any
Company director or officer.

      10.   PERIOD OF LIMITATIONS. No legal action shall be brought and no cause
of action shall be asserted by or on behalf of the Company or any affiliate of
the Company against Indemnitee, Indemnitee's spouse, heirs, executors or
personal or legal representatives after the expiration of two years from the
date of accrual of such cause of action, or such longer period as may be
required by state law under the circumstances, and any claim or cause of action
of the Company or its affiliate shall be extinguished and deemed released unless
asserted by the timely filing of a legal action within such period; provided,
however, that if any shorter period of limitations is otherwise applicable to
any such cause of action, such shorter period shall govern.

      11.   AMENDMENT OF THIS AGREEMENT. No supplement, modification or
amendment of this Agreement shall be binding unless executed in writing by both
of the parties hereto. No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provisions hereof
(whether or not similar), nor shall such waiver constitute a continuing waiver.
Except as specifically provided herein, no failure to exercise or any delay in
exercising any right or remedy hereunder shall constitute a waiver thereof.

      12.   SUBROGATION. In the event of payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all papers required and shall do
everything that may be necessary to secure such rights, including the execution
of such documents necessary to enable the Company effectively to bring suit to
enforce such rights.

      13.   NO DUPLICATION OF PAYMENTS. The Company shall not be liable under
this Agreement to make any payment in connection with any claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, Bylaw or otherwise) of the amounts otherwise
indemnifiable hereunder.

      14.   SETTLEMENT OF CLAIMS. The Company shall not be liable to indemnify
Indemnitee under this Agreement for any amounts paid in settlement of any action
or claim effected without the Company's written consent. The Company shall not
settle any action or claim in any manner which would impose any penalty or
limitation on Indemnitee without Indemnitee's written consent. Neither the
Company nor the Indemnitee will unreasonably withhold their consent to any
proposed settlement. The Company shall not be liable to indemnify the Indemnitee
under this Agreement with regard to any judicial award if the Company was not
given a reasonable and timely opportunity, at its expense, to participate in the
defense of such action.

      15.   BINDING EFFECT. This Agreement shall be binding upon and inure to
the benefit of and be enforceable by the parties hereto and their respective
successors, assigns, including any

Ralph Yarro Indemnification

                                       7
<PAGE>

direct or indirect successor by purchase, merger, consolidation or otherwise to
all or substantially all of the business and/or assets of the Company, spouses,
heirs, and personal and legal representatives. The Company shall require and
cause any successor (whether direct or indirect by purchase, merger,
consolidation or otherwise) to all, substantially all, or a substantial part, of
the business and/or assets of the Company, by written agreement in form and
substance satisfactory to the Indemnitee, expressly to assume and agree to
perform this Agreement in the same manner and to the same extent that the
Company would be required to perform if no such succession had taken place. This
Agreement shall continue in effect regardless of whether Indemnitee continues to
serve as a director or officer of the Company or of any other enterprise at the
Company's request.

      16.   SEVERABILITY. The provisions of this Agreement shall be severable in
the event that any of the provisions hereof (including any provision within a
single section, paragraph or sentence) is held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this agreement
(including, without limitation, each portion of this Agreement containing any
provision held to be invalid, void or otherwise unenforceable, that is not
itself invalid, void or unenforceable) shall be construed so as to give effect
