                           ASSET PURCHASE AGREEMENT

          THIS ASSET PURCHASE AGREEMENT (this "Agreement"), dated as of August
6, 1999, is entered into by and among HDA Parts System, Inc., an Alabama
corporation ("HDA"), and Certified Power, Inc., a Minnesota corporation
("Certified Power"). HDA and Certified Power are referred to herein as each a
"Party" and collectively, the "Parties."

                                   RECITALS

          WHEREAS, Certified Power owns certain Assets (as defined in Annex A)
that are used or held for use in the "Business," as defined hereinafter. The
term "Business" means the portion of the business of Certified Power based in
Toledo, Ohio, consisting solely of that portion of the business of Certified
Power that distributes and remanufactures the product lines identified on the
attachment to Annex A as included in the Assets to the domestic Class 7 and
Class 8 heavy duty truck market from such location based in Toledo, Ohio, but
excluding the fluid power business of Certified Power; and

          WHEREAS, HDA desires to acquire the Assets, other than the Excluded
Assets (as defined in Annex A);

                                   AGREEMENT

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements set forth herein, the Parties hereby agree as follows:

                                  ARTICLE I.
                               PURCHASE AND SALE

          1.1. Estimated Purchase Price. Upon the terms and subject to the
               ------------------------
conditions set forth herein, HDA will purchase from Certified Power the Assets
for an aggregate purchase price (the "Estimated Purchase Price") of $6,415,000
in cash payable by wire transfer of immediately available funds to Certified
Power.

          1.2. Post-Closing Purchase Price Adjustment.
               --------------------------------------

          (a)  Closing Balance Sheet. Certified Power will prepare at its
               ---------------------
expense a balance sheet of the Business dated the Closing Date (the "Closing
Balance Sheet"), prepared from its books and records and prepared in accordance
with generally accepted accounting principles ("GAAP"). Certified Power will
also prepare a calculation, as of the Closing Date based on the Closing Balance
Sheet, of Net Book Value ("Closing Net Book Value"), which calculation will be
prepared in accordance with GAAP and on a basis consistent with the Net Book
Value calculation reflected on Schedule 1.2 hereto. Certified Power will deliver
such Closing Balance Sheet and such calculation to HDA within 30 days after the
Closing. For the purpose of Certified Power's preparation of the Closing Balance
Sheet and the calculation of Closing Net Book Value, HDA shall afford Certified
Power and Certified Power's agents and representatives reasonable access to all
books, records and


work papers of the Business necessary for Certified Power's preparation of the
Closing Balance Sheet and the calculation of Closing Net Book Value.

          (b)  Closing Balance Sheet Notice.
               ----------------------------

               (i)   Within 15 days of the receipt of the Closing Balance Sheet
     and the calculation of Closing Net Book Value, HDA will deliver to
     Certified Power a written notice certifying that either (A) it agrees with
     such Closing Balance Sheet and calculation or (B) it disagrees with such
     Closing Balance Sheet and calculation, in which case HDA will also provide
     therewith a reasonably detailed written report stating the basis for
     disagreement with such Closing Balance Sheet and such calculation (the
     "Closing Balance Sheet Notice").

               (ii)  If the Closing Balance Sheet Notice is not timely given as
     described in Section 1.2(b)(i), the Closing Balance Sheet and the
     calculation of Closing Net Book Value shall be final, binding and
     conclusive upon the Parties. If the Closing Balance Sheet Notice is
     properly given and Certified Power disagrees with such Closing Balance
     Sheet Notice, and if the disagreement is not resolved by mutual agreement
     between the Parties within 30 days following delivery of the Closing
     Balance Sheet Notice, such dispute will be resolved by a "Big 5" accounting
     firm ("BFAF"), other than PricewaterhouseCoopers LLP, selected by mutual
     agreement of HDA and Certified Power. The costs of resolving such a dispute
     shall be borne equally by HDA and Certified Power.

               (iii) Upon appointment of a BFAF, such BFAF in consultation with
     the Parties shall establish a schedule for resolution of the dispute that
     is reasonably calculated to result in a resolution as expeditiously as
     practicable, and in any event, no later than six months after the Closing
     Date. In resolving such dispute, the BFAF shall revise the Closing Balance
     Sheet and the calculation of Closing Net Book Value only with respect to
     the issues raised in the Closing Balance Sheet Notice and only to the
     extent necessary to make it conform to the practices, procedures and
     methods described in Section 1.2(a) above. The decision of the BFAF shall
     be final and binding on the Parties in the absence of manifest error.

          (c)  Post-Closing Adjustment. Within two business days after a final
               -----------------------
resolution by the BFAF of such disagreements as may arise out of the review of
the Closing Balance Sheet in accordance with Section 1.2(b) above, and an
appropriate adjustment to the Closing Balance Sheet and the calculation of
Closing Net Book Value to reflect such resolution, or, if Section 1.2(b)(i)(A)
or the first sentence of Section 1.2(b)(ii) applies, two business days after
delivery of, or expiration of the period for delivering, the Closing Balance
Sheet Notice (as applicable), the Estimated Purchase Price will be adjusted (as
so adjusted, the "Purchase Price"). If Closing Net Book Value is less than
$2,170,000, the difference and interest thereon will be due and payable to HDA
by Certified Power; however, to the extent Closing Net Book Value is more than
$2,270,000, the excess and interest thereon will be due and payable to Certified
Power by HDA. Any amounts payable pursuant to this paragraph shall bear interest
from the Closing Date through the date of payment at an annual rate equal to one
month LIBOR as reported in The Wall Street Journal on the Closing Date.

          1.3. Transfer of Assets. Upon the terms and subject to the conditions
               ------------------
set forth herein, at the Closing, Certified Power will sell to HDA, and HDA will
purchase from Certified

                                       2


Power, the Assets, free and clear of all encumbrances other than Permitted
Encumbrances (as defined in Section 3.4).

          1.4. Assumption of Liabilities. Upon the terms and subject to the
               -------------------------
conditions contained herein, at the Closing, HDA shall assume and shall
thereafter pay, perform and discharge as and when due the liabilities and
obligations of the Business arising out of accounts payable of the Business
outstanding as of the Closing Date and calculated in a manner consistent with
Schedule 1.2 hereto, and only those liabilities and obligations, together with
all liabilities and obligations arising out of the operation of the Business and
the ownership of the Assets after the Closing Date (the "Assumed Liabilities").

          1.5. Excluded Liabilities. Notwithstanding any other provision of
               --------------------
this Agreement, except for the Assumed Liabilities, HDA shall not assume, or
otherwise be responsible for, Certified Power's other liabilities or
obligations, whether actual or contingent, matured or unmatured, liquidated or
unliquidated, known or unknown, or related or unrelated to the Business or the
Assets, whether arising out of occurrences prior to or at the Closing Date (such
other liabilities and obligations, collectively, the "Excluded Liabilities"),
which Excluded Liabilities include, without limitation:

          (a)  All liabilities and obligations of Certified Power arising out of
or related to any of the Excluded Assets;

          (b)  All liabilities and obligations of Certified Power in respect of
any costs arising out of or related to the sale and transfer of the Assets,
including without limitation, all broker's or finder's fees and expenses and all
fees and expenses of any attorneys and accountants of Certified Power;

          (c)  All liabilities and obligations of Certified Power in respect of
any Tax (as defined in Section 3.8) relating to the Business or the Assets
attributable to any period ending on or before the Closing Date;

          (d)  All liabilities and obligations to or in respect of any employees
or former employees, agents or independent contractors of, or other persons
providing services to, the Business that shall have been asserted on or prior to
the Closing Date or are based on acts or omissions that occurred on or prior to
the Closing Date, including, without limitation, (i) any employment, incentive
or severance agreement, whether or not written, between Certified Power and any
person, (ii) all liabilities under any Employee Benefit Plan (as defined in
Section 3.15(a)) at any time maintained, contributed to or required to be
contributed to by or with respect to Certified Power or under which Certified
Power may incur liability, or any contributions, benefits or liabilities
therefor, or any liability with respect to Certified Power's withdrawal or
partial withdrawal from or termination of any Employee Benefit Plan and (iii)
all claims of an unfair labor practice, or any claim under any state
unemployment compensation or worker's compensation law or regulation or under
any federal or state employment discrimination law or regulation;

          (e)  All liabilities and obligations of Certified Power relating to
any claim, suit, litigation, proceeding or investigation pending on the date
hereof, or instituted hereafter, that is based in whole or in part on events or
conditions occurring or existing in connection with, arising out of,

                                       3


resulting from or relating to, directly or indirectly, the operation of the
Business prior to the Closing Date, or the ownership, possession, use or sale of
the Assets prior to the Closing Date;

          (f)  All liabilities and obligations of the Business arising out of or
related to any indebtedness for borrowed money owing to Certified Power or any
of its affiliates;

          (g)  All claims, liabilities or obligations (including, without
limitation, fines, penalties, punitive damages, legal fees and expenses and all
other damages and losses), irrespective of the actual or alleged basis therefor,
that is based in whole or in part on events or conditions occurring or existing
prior to the Closing in connection with, arising out of, resulting from or
relating to, directly or indirectly, (i) any applicable laws regulating or
establishing quality criteria or standards for air, water, land, noise or
industrial safety and health, providing for remediation of environmental
conditions or otherwise relating to the environment, whether existing as of the
date hereof or subsequently amended, enacted or promulgated, (ii) employee
health and safety or (iii) compliance with any laws or regulations relating to
any of the foregoing;

          (h)  All liabilities and obligations arising from or relating to any
injury to or death of any person or damage to or destruction of any property,
whether based on negligence, breach of warranty, strict liability, enterprise
liability or any other legal or equitable theory arising, in whole or in part,
from defects in products sold or services performed by or on behalf of the
Business or any other person or entity on or prior to the Closing Date (except
for liabilities and obligations arising from any such portion of a claim (i)
based upon breach of manufacturer's warranty or (ii) arising in connection with
a defect in a product that was not manufactured, remanufactured or otherwise
enhanced by the Business), or arising from any other cause, irrespective of the
act and/or alleged basis therefor, that is based in whole or in part on events
or conditions occurring or existing on or prior to the Closing Date, including
without limitation any liabilities arising (on a date of occurrence basis or
otherwise) relating to the use or misuse of equipment or to traffic accidents;
and

          (i)  Without limitation by the specific enumeration of the foregoing,
any liabilities not expressly assumed by, or subject to indemnification
obligations of, HDA.

          1.6. Allocation of Purchase Price. The sum of (a) the Purchase Price
               ----------------------------
(as adjusted pursuant to Section 1.2 hereof) plus (b) the Assumed Liabilities
(collectively, the "Allocable Amount") represents the amount agreed upon by the
Parties to be the aggregate consideration paid for the Assets, and shall be
allocated among the Assets in accordance with a schedule (the "Allocation
Schedule") to be agreed after the Closing Date by HDA and Certified Power. The
allocations contained in that Allocation Schedule will, in general, be based and
allocated in the following manner: (x) accounts payable will be based upon book
value; (y) accounts receivable, fixed assets and inventory will be based upon
net book value; and (z) the balance of the Purchase Price will be allocated to
goodwill. Certified Power shall prepare and deliver the Allocation Schedule to
HDA for its review and approval within 45 days after the period for making any
adjustment to the Purchase Price expires (as provided in Section 1.2 hereof),
and HDA shall deliver to Certified Power any proposed adjustment thereto within
30 days of its receipt of the Allocation Schedule. If HDA does not deliver to
Certified Power proposed adjustments to the Allocation Schedule within such
time, it shall be deemed to agree with the Allocation Schedule as prepared by
Certified Power. In the event of any disagreement, HDA and Certified Power shall
negotiate in good faith for a resolution of the allocation. If the disagreement
is not resolved by mutual agreement between the Parties within 30 days following
delivery by HDA of such proposal adjustments to the

                                       4


Allocation Schedule, such dispute will be resolved by a BFAF, other than
PricewaterhouseCoopers LLP, selected by mutual agreement of HDA and Certified
Power. The costs of resolving such a dispute shall be borne equally by HDA and
Certified Power. Upon appointment of a BFAF, such BFAF shall establish a
schedule for resolution of the dispute that is reasonably calculated to result
in a resolution as expeditiously as practicable, and in any event, no later than
six months after the Closing Date. In resolving such dispute, the BFAF shall
revise the Allocation Schedule only with respect to the issues raised in HDA's
notice to Certified Power proposing adjustments to the Allocation Schedule. The
decision of the BFAF shall be final and binding on the Parties in the absence of
manifest error. The Allocation Schedule shall comply with the requirements of
Section 1060 of the Internal Revenue Code of 1986, as amended (the "Code"), and
the regulations promulgated thereunder. HDA and Certified Power shall (i) report
for all Tax purposes the purchase of the Assets in a manner consistent with the
Allocation Schedule and in a manner consistent with all applicable rules and
regulations; (ii) timely file a Form 8594 in accordance with the requirements of
Section 1060 of the Code and this Section 1.6; (iii) not assert, in connection
with any Tax Return, Tax audit or similar proceedings, any allocation of the
Allocable Amount that differs from that agreed to herein; and (iv) notify the
other in the event any taxing authority is taking or proposing to take a
position inconsistent with such allocation.

corporation duly organized, validly existing and in good standing under the laws
of the State of Minnesota and has all requisite corporate power and authority to

               -------------
defined in Section 6.4) have been duly authorized, executed and delivered by
Certified Power, and this Agreement and the Ancillary Agreements are the legal,
valid and binding obligations of Certified Power, enforceable against it in
accordance with their terms.

          3.3. No Conflict or Violation. Neither the execution and delivery of
               ------------------------
this Agreement or the Ancillary Agreements nor the consummation of the
transactions contemplated hereby or thereby will (a) violate, conflict with or
result in or constitute a default under or result in the termination or the
acceleration of, or the creation in any party of any right (whether or not with
notice or lapse of time or both) to declare a default, accelerate, terminate,
modify or cancel any indenture, contract, lease, sublease, loan agreement, note

transfer contemplated hereby will vest indefeasible and exclusive title to the
Assets in HDA, free and clear of all encumbrances of any kind other than
Permitted Encumbrances.  The Assets and the Excluded Assets constitute all of

          3.12. Proprietary Rights.
                ------------------

          (a)   Schedule 3.12 lists the material patents, trademarks (whether
registered or unregistered), service marks, trade names, service names, brand
names, logos and copyrights (collectively, the "Proprietary Rights") used in the
Business.  Schedule 3.12 also sets forth:  (i) for each such patent, the number,
normal expiration date and subject matter for each country in which such patent
has been issued, or, if applicable, the application number, date of filing and
subject matter for each country, (ii) for each such trademark, the application
serial number or registration number, the class of goods covered and the
expiration date for each country in which a trademark has been registered and
(iii) for each such copyright, the number and date of filing for each country in
which a copyright has been filed.  The Proprietary Rights listed in Schedule
3.12 are all those used by Certified Power in connection with the Business or
the Assets.  True and correct copies of all such patents (including all pending
applications) owned, controlled, created or used by or on behalf of the Business
or in which Certified Power has any interest whatsoever have been provided to
HDA or its representatives.

          (b)   Certified Power does not have any obligation to compensate any
person for the use of any such Proprietary Rights.  Certified Power has not
granted to any person any license, option or other rights to use in any manner
any of Proprietary Rights, whether requiring the payment of royalties or not.

          (c)   Certified Power owns or has a valid right to use each of the
Proprietary Rights, and the Proprietary Rights will not cease to be valid rights
by reason of the execution, delivery and performance of this Agreement, the
Ancillary Agreements or the consummation of the transactions contemplated hereby
and thereby. All of the pending patent applications have been duly filed.
Certified Power has not received any notice of invalidity or infringement of any
rights of others with respect to such trademarks. Certified Power has taken all
reasonable and prudent steps

                                       11


to protect the Proprietary Rights from infringement by any other person. To the
best of Certified Power's knowledge, no other person (i) has the right to use
any trademarks of the Business that are included in the Assets on the goods on
which they are now being used either in identical form or in such near
resemblance thereto as to be likely, when applied to the goods of any such
person, to cause confusion with such trademarks or to cause a mistake or to
deceive, (ii) has notified Certified Power that it is claiming any ownership of
or right to use such Proprietary Rights, or (iii) to the best knowledge of
Certified Power, is infringing upon any such Proprietary Rights in anyway. To
the best of Certified Power's knowledge, Certified Power's use of any
Proprietary Rights does not conflict with, infringe upon or otherwise violate
the valid rights of any third party in or to such Proprietary Rights, and no
Action has been instituted against or notices received by Certified Power that
are presently outstanding, alleging that Certified Power's use of the
Proprietary Rights infringes upon or otherwise violates any rights of a third
party in or to such Proprietary Rights. There are not, and, to the best of
Certified Power's knowledge, after the Closing there will not be, any material
restrictions on Certified Power's right to sell products manufactured in
connection with the operation of the Business.

          3.13. Labor Matters.  Certified Power is not a party to any labor
                -------------
agreement with respect to the employees of the Business with any labor
organization, union, group or association, and there are no employee unions (or
any other similar labor or employee organizations) under local statutes, custom
or practice.  Certified Power has not experienced any attempt within the past
five years by organized labor or its representatives to make it conform to
demands of organized labor relating to the employees of the Business enter into
a binding agreement with organized labor that would cover the employees of the
Business.  There is no labor strike or labor disturbance pending or, to the best
knowledge of Certified Power, threatened against the Business, nor is any
grievance currently being asserted, and the Business has not experienced a work
stoppage or other labor difficulty in the past five years, and is not and has
not engaged in any unfair labor practice.  Without limiting the foregoing, the
Business is in compliance with the Immigration Reform and Control Act of 1986
and maintains a current Form I-9 as required by such Act, in the personnel file
of each employee of the Business hired after November 9, 1986.

          3.14. Consents.  No consent, approval, authorization, order, filing,
                --------
registration or qualification of or with any court, governmental authority or
third person is required to be made or obtained by Certified Power in connection
with the execution and delivery of this Agreement, the Ancillary Agreements or
the consummation by Certified Power of the transactions contemplated herein and
therein.

shall use its reasonable efforts to provide to HDA the benefits of any such
Assigned Agreement, shall enforce, at HDA's request and for HDA's account, any
rights of Certified Power under such Assigned Agreement (including the right to
elect, renew, extend or terminate) and shall promptly pay to HDA when received
all monies received by Certified Power under such Assigned Agreement.  To the
extent HDA is provided the benefit of any such Assigned Agreement, HDA shall
perform or discharge, on behalf of Certified Power, Certified Power's
obligations and liabilities under each such Assigned Agreement in accordance
with the provisions thereof.  This Section 8.1 shall not be construed to require
HDA to assume any additional liability hereunder or to perform under or assume
any obligations with respect to the Assigned Agreements in excess of those
currently required by such Assigned Agreements.  Certified Power shall use its
reasonable efforts to ensure that all contracts entered into by Certified Power
after the date hereof that relate to the Business or the Assets are assignable
to HDA without the consent of the other party thereto.

          8.2. Trade Names.  Certified Power shall, and shall cause its
               -----------
affiliates to, as soon as reasonably practicable following the Closing Date,
cease to use any trade names, trademarks, services marks, logos, designs or
similar rights and interests included in the Assets, including the

                                       21


name "The Toledo Clutch and Brake Service, Inc." or any abbreviation or
variation thereof (the "Acquired Name"), in the operation of their business,
including on any plant, building or equipment or any stationery, business form,
packaging, container, sign or other property (real or personal) included in the
Excluded Assets.

          8.3. Indemnification by Certified Power.  Subject to the provisions of
               ----------------------------------
this Article VIII, Certified Power agrees to indemnify, defend and hold HDA and
its affiliates, stockholders, subsidiaries, officers, directors, employees,
agents, successors and assigns, (such indemnified persons are collectively
hereinafter referred to as "HDA Indemnified Persons"), harmless from and against
any and all loss, liability, damage or deficiency (including interest,
penalties, judgments, costs of preparation and investigation, and reasonable
attorneys' fees) (collectively, "Losses") that any HDA Indemnified Person may
suffer, sustain, incur or become subject to arising out of or due to: (a) the
Excluded Liabilities or the Excluded Assets; (b) the nonfulfillment of any
covenant, undertaking, agreement or other obligation of Certified Power under
this Agreement, any Schedule hereto or any Ancillary Agreement, not otherwise
waived by HDA; (c) any inaccuracy of any representation of Certified Power in
this Agreement, any Schedule hereto or any Ancillary Agreement; or (d) the
breach of any warranty of Certified Power in this Agreement, any Schedule hereto
or any Ancillary Agreement.  "Losses" as used in this Article VIII is not
limited to matters asserted by third parties, but includes Losses incurred or
sustained in the absence of third party claims.  Payment is not a condition
precedent to recovery of indemnification for Losses.  Certified Power shall not
be liable for indemnification with respect to any matter to the extent such
matter results in a purchase price adjustment pursuant to Section 1.2 above to
the extent of such purchase price adjustment, regardless of whether or not such
matter constitutes a breach of any representation or warranty of Certified Power
as stated in this Agreement.

          8.4. Indemnification by HDA.  Subject to the provisions of this
               ----------------------
Article VIII, HDA agrees to indemnify, defend and hold Certified Power and its
affiliates, stockholders, subsidiaries, officers, directors, employees, agents,
successors and assigns (such persons are hereinafter collectively referred to as
"Certified Power Indemnified Persons"), harmless from and against any and all
Losses that Certified Power Indemnified Persons may suffer, sustain, incur or
become subject to arising out of or due to: (a) the Assumed Liabilities or the
Assets; (b) the nonfulfillment of any covenant, undertaking, agreement or other
obligation of HDA under this Agreement, any Schedule hereto or any Ancillary
Agreement, not otherwise waived by Certified Power; (c) any inaccuracy of any
representation of HDA in this Agreement, in any Schedule hereto or any Ancillary
Agreement; or (d) the breach of any warranty of HDA in this Agreement or any
Schedule hereto.  Payment is not a condition precedent to recovery of
indemnification for Losses.

          8.5. Survival of Representations, Warranties and Covenants.  The
               -----------------------------------------------------
several representations, warranties and covenants of the Parties contained in
this Agreement or in any document delivered pursuant hereto and the Parties'
right to indemnity in accordance with this Article VIII shall survive the
Closing Date and shall remain in full force and effect for one year thereafter,
at which time all such claims shall terminate except such claims as the parties
may have to the amounts held by the Escrow Agent pursuant to the terms of the
Escrow Agreement; provided, however, that the representations and warranties set
                  --------  -------
forth in Section 3.8 relating to tax matters, Section 3.15 relating to employee
benefits matters and Section 3.16 relating to environmental matters shall
survive for the length of the applicable statute of limitations.

                                       22


          8.6. Threshold; Deductible; Maximum.  No HDA Indemnified Person or
               ------------------------------
Certified Power Indemnified Person shall be entitled to any recovery in
accordance with this Article VIII unless and until the amount of such Losses
suffered, sustained or incurred by such party, or to which such party becomes
subject, by reason of such inaccuracy, breach or nonfulfillment exceeds $50,000
and then only to the extent of such excess.  The maximum aggregate amount to be
paid under this Article VIII by Certified Power or HDA shall not exceed the
Purchase Price.

          8.7. Sole and Exclusive Remedy.  The indemnification obligations of
               -------------------------
Certified Power and HDA under this Article VIII shall constitute the sole and
exclusive remedies of Certified Power or HDA, respectively, for the recovery of
money damages with respect to any and all claims sounding in contract arising
out of or in connection with this Agreement, except for any claims for fraud,
willful misconduct or intentional misrepresentation.  The terms of this Section
8.7 shall not be construed as limiting in any way whatsoever any remedy other
than for the recovery of money damages to which Certified Power or HDA may be
entitled.

          8.8. Notice and Opportunity to Defend.  If a claim for Losses (a
               --------------------------------
"Claim") is to be made by a party seeking indemnification hereunder, such party
seeking indemnification (the "Indemnitee") shall notify the party obligated to
provide indemnification (the "Indemnitor") promptly.  If such event involves (a)
any claim or (b) the commencement of any action or proceeding by a third person,
the Indemnitee shall give the Indemnitor written notice of such claim or the
commencement of such action or proceeding.  Delay or failure to so notify the
Indemnitor shall only relieve the Indemnitor of its obligations to the extent,
if at all, that it is prejudiced by reasons of such delay or failure.  The
Indemnitor shall have a period of 30 days within which to respond thereto.  If
the Indemnitor accepts responsibility or does not respond within such 30-day
period, then the Indemnitor shall be obligated to compromise or defend, at its
own expense and by counsel chosen by the Indemnitor, such matter, and the
Indemnitor shall provide the Indemnitee with such assurances as may be
reasonably required by the Indemnitee to assure that the Indemnitor will assume
and be responsible for the entire liability at issue, subject to the limitations
set forth in Sections 8.5 and 8.6 hereof.  If the Indemnitor fails to assume the
defense of such matter within said 30-day period, the Indemnitee against which
such matter has been asserted will (upon delivering notice to such effect to the
Indemnitor) have the right to undertake, at the Indemnitor's cost and expense,
the defense, compromise or settlement of such matter on behalf of the
Indemnitee.  The Indemnitee agrees to cooperate fully with the Indemnitor and
its counsel in the defense against any such asserted liability.  In any event,
the Indemnitee shall have the right to participate at its own expense in the
defense of such asserted liability.  Any compromise of such asserted liability
by the Indemnitor shall require the prior written consent of the Indemnitee,
which consent will not be unreasonably withheld and in the event the Indemnitee
defends any such asserted liability, then any compromise of such asserted
liability by the Indemnitee shall require the prior written consent of the
Indemnitor, which consent shall not be unreasonably withheld.

          8.9. Indemnification Payments.  At the Closing, HDA will deliver by
               ------------------------
wire transfer of immediately available funds $350,000 (Three Hundred Fifty
Thousand Dollars) of the Estimated Purchase Price to the Escrow Agent to be held
by the Escrow Agent for one year pursuant to the terms of the Escrow Agreement
and to serve as partial security for the indemnification obligations of
Certified Power under this Agreement.  Any indemnification obligations of
Certified Power under this Article VIII shall be first satisfied by amounts held
by the Escrow Agent pursuant to the terms of the Escrow Agreement.
