                                                                  [PIONEER LOGO]

                          CHANGE OF CONTROL AGREEMENT
                          ---------------------------

         THIS CHANGE OF CONTROL AGREEMENT by and between Pioneer-Standard
Electronics, Inc., an Ohio Corporation (the "Company"), and Thomas G. Pitera
(the "Employee"), is dated as of the 25th day of February, 2000.

                                  WITNESSETH:
                                  -----------

         WHEREAS, the Board of Directors of the Company (the "Board"), has
determined that it is in the best interests of the Company and its shareholders
to assure that the Company will have the continued dedication of the Employee,
notwithstanding the possibility, threat, or occurrence of a Change of Control
(as defined below) of the Company; and

         WHEREAS, the Board believes it is imperative to diminish the inevitable
distraction of the Employee by virtue of the personal uncertainties and risks
created by a pending or threatened Change of Control, to encourage the
Employee's full attention and dedication to the Company currently and in the
event of any threatened or pending Change of Control, and to provide the
Employee with compensation arrangements upon a Change of Control which provide
the Employee with individual financial security and which are competitive with
those of other corporations;

         NOW, THEREFORE, in consideration of the mutual covenants set forth
herein and other good and valuable consideration, the receipt and adequacy of
which is hereby acknowledged, the parties hereto agree as follows:

Section 1. EFFECTIVE DATE AND CHANGE OF CONTROL.

         1.1   (a)  EFFECTIVE DATE. This Agreement shall become effective only
upon the "Effective Date," which shall be the first date during the "Change of
Control Period" (as defined in Section 1.1(b)) on which a Change of Control (as
defined in Section 1.2) occurs. Until such time, the Employee shall have no
rights against the Company and the Company shall not have any obligations to the
Employee under or by virtue of this Agreement. Anything in this Agreement to the
contrary notwithstanding, if the Employee's employment with the Company is
terminated prior to the date on which a Change of Control occurs, and it is
reasonably demonstrated that such termination (1) was at the request of a third
party who has taken steps reasonably calculated to effect a Change of Control or
(2) otherwise arose in Connection with or anticipation of a Change of Control,
then for all purposes of this Agreement the "Effective Date" shall mean the date
immediately prior to the date of such termination.

         (b) The "Change of Control Period" is the period commencing on the date
hereof and ending on the first anniversary of such date; provided, however, that
commencing on the date one (1) year after the date hereof, and on each annual
anniversary of such date (such date and each annual anniversary thereof is
hereinafter referred to as the "Renewal Date"), the Change of Control Period
shall be automatically extended so as to terminate one (1) year from such
Renewal Date, unless the Company shall give written notice to the Employee at
least sixty (60) days prior to the Renewal Date that the Change of Control
Period shall not be so extended and that this Agreement shall terminate upon the
Renewal Date; provided, however, that such notice may not be given at any time
during the nine (9) month period following the Effective Date.

         1.2 CHANGE OF CONTROL. For the purpose of this Agreement, a "Change of
Control" shall mean:

                 (a) The acquisition by any person, entity or "group," within
the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
1934 (the "Exchange Act") (excluding, for this purpose, the Company or its
Subsidiaries, The Pioneer Stock Benefit Trust, or any employee benefit plan of
the Company or its Subsidiaries which acquires beneficial ownership of voting
securities of the Company), of beneficial ownership (within the meaning of Rule
13d-3 promulgated under the Exchange Act) of 20% or more of either the then
outstanding Common Shares or the combined voting power of the Company's then
outstanding voting securities entitled to vote generally in the election of
directors; or

                (b) Individuals who, as of the date hereof, constitute the Board
(as of the date hereof the "Incumbent Board") cease for any reason to constitute
at least a majority of the Board, provided that any person becoming a director
subsequent to the date hereof whose election, or nomination for election by the
Company's shareholders, was approved by a vote of at least a majority of the
directors then comprising the Incumbent Board (other than an election or
nomination of an individual whose initial assumption of office is in connection
with an actual or threatened election contest relating to the election of the
Directors of the Company, as such terms are used in Rule 14a-11 of Regulation
14A promulgated under the Exchange Act) shall be, for purposes of this
Agreement, considered as though such person were a member of the Incumbent
Board; or

                (c) Approval by the shareholders of the Company of a
reorganization, merger, consolidation, in each case, with respect to which
persons who were the shareholders of the Company immediately prior to such
reorganization, merger or consolidation do not, immediately thereafter, own more
than 80% of the combined voting power entitled to vote generally in the election
of directors of the reorganized, merged or consolidated company's then
outstanding voting securities, or a liquidation or dissolution of the Company or
of the sale of all or substantially all of the assets of the Company.

Section 2. TERMINATION OF EMPLOYMENT.

         2.1 TERMINATION BY THE COMPANY.

         (a) COMPANY'S RIGHT TO TERMINATE. Subject to (i) the Company's
obligations under Section 3.1 hereof subsequent to the Effective Date, or (ii)
under any written employment agreement between the Company and the Employee, the
Employee's employment with the Company may be terminated at any time without
Cause.

         (b) CAUSE. The Company may terminate the Employee's employment for
"Cause." For purposes of this Agreement, "Cause" means (i) an act or acts of
personal dishonesty taken by the Employee and intended to result in personal
enrichment of the Employee at the expense of the Company or (ii) the conviction
of the Employee of a felony.

         2.2 TERMINATION BY THE EMPLOYEE.

         The Employee's employment with the Company (i) shall automatically
terminate upon death and (ii) may be voluntarily terminated by the Employee at
any time for any reason, in the Employee's sole discretion.

         2.3 TRANSFERS. Transfer of the Employee among the Company and
affiliated entities at least 80% directly or indirectly owned by the Company
("Subsidiaries") shall not be deemed to be a termination of employment.

         2.4 NOTICE OF TERMINATION.

         Any termination by the Company or by the Employee shall be communicated
by Notice of Termination to the other party hereto given in accordance with
Section 8(d) of this Agreement. For purposes of this Agreement, a "Notice of
Termination" means a written notice which (i) indicates the specific termination
provision in this Agreement relied upon, (ii) in the case of a termination for
Cause, sets forth in reasonable detail the facts and circumstances claimed to
provide a basis for termination of the Employee's employment under the provision
so indicated, and (iii) if the date of termination is other than the date of
receipt of such notice, specifies the date of termination (which date shall be
not more than fifteen (15) days after the giving of such notice).

Section 3. OBLIGATIONS OF THE COMPANY UPON TERMINATION.

         3.1 WITHOUT CAUSE OR VOLUNTARY TERMINATION. If, at any time
prior to the date that is twelve (12) months subsequent to the Effective Date,
the Employee's employment with the Company shall be terminated either (i) by the
Company without Cause, or (ii) by the Employee voluntarily for any reason:

                 (a) the Company shall pay to the Employee within thirty (30)
days of the date of termination a lump sum amount equal to twenty-four (24)
times the greater of the Employee's (i) highest monthly base salary paid or
payable by the Company during the twelve (12) month period immediately preceding
the Effective Date, or (ii) the highest monthly salary paid or payable by the
Company at any time from the ninety (90) day period preceding the Effective Date
through the date of termination (the "Highest Base Salary"); and

                 (b) the Company shall pay to the Employee within thirty (30)
days of the date of termination a lump sum amount equal to the greater of (i)
four (4) times the highest aggregate amount of incentive compensation paid or
payable by the Company to the Employee during any six (6) consecutive months of
the twelve (12) month period immediately preceding the Effective Date under any
and all incentive compensation plan(s) of the Company in effect at such time; or
(ii) four (4) times the highest aggregate amount of incentive compensation paid
or payable by the Company to the Employee during any six (6) consecutive months
of the twelve (12) month period preceding the date of termination under any and
all incentive compensation plan(s) of the Company in effect at such time; and

                (c) the Company shall pay to the Employee within thirty (30)
days of the date of termination a lump sum amount equal to twenty-four (24)
times the monthly amount paid or payable to Employee by the Company as an auto
allowance as in effect immediately preceding the Effective Date; and

                (d) a cash payment equal to the amount of excise taxes (i.e.,
the "excise tax gross-up payment") which the Employee would be required to pay
pursuant to Section 4999 of the Internal Revenue Code of 1986, as amended
("Code"), as a result of any payments made by or on behalf of the Company or any
successor thereto resulting in an "excess parachute payment" within the meaning
of Section 280G(b) of the Code. In addition to the foregoing, the cash payment
due to the Employee under this section 3.1(d) shall be increased by the
aggregate of the amount of federal, state and local income and excise taxes for
which the Employee will be liable on account of the cash payment to be made
under this section 3.1(d), such that the Employee will receive the excise tax
gross-up payment net of all income and excise taxes imposed on the Employee on
account of the receipt of the excise tax gross-up payment. The computation of
this payment shall be determined, at the expense of the Company, by an
independent accounting, actuarial or consulting firm selected by the Company.
Payment of the cash amount set forth

<PAGE>   4

above shall be made at such time as the Company shall determine, in its sole
discretion, but in no event later than the date five (5) business days before
the due date, without regard to any extension, for filing the Employee's federal
income tax return for the calendar year which includes the date as of which the
aforementioned "excess parachute payments" are determined. Notwithstanding the
foregoing, there shall be no duplication of payments by the Company under this
section 3.1(d) in respect of excise taxes under Section 4999 of the Code to the
extent the Company is making cash payments in respect of such excise taxes for
any other arrangement with the Employee. In the event that the Employee is
ultimately assessed with excise taxes under Section 4999 of the Code as a result
of payments made by the Company or any successor thereto which exceed the amount
of excise taxes used in computing the Employee's payment under this section
3.1(d), the Company or its successor shall indemnify the Employee for such
additional excise taxes plus any additional taxes, income taxes, interest and
penalties resulting from the additional excise taxes and the indemnity
hereunder; and

                (e) for the twenty-four (24) month period following the date of
termination (the "Benefits Continuation Period"), the Company shall continue to
provide health insurance and retirement benefits to the Employee and/or the
Employee's family at least equal to those which would have been provided to them
if the Employee's employment had not been terminated, in accordance with the
most favorable plans, practices, programs or policies of the Company and its
Subsidiaries during the ninety (90) day period immediately preceding the
Effective Date or, if more favorable to the Employee, as in effect at any time
thereafter with respect to other key employees and their families, and for
purposes of eligibility for retirement benefits pursuant to such plans,
practices, programs and policies, the Employee shall be considered to have
remained employed until the end of the Benefits Continuation Period and to have
retired on the last day of such period. Notwithstanding the foregoing, the
Employee shall have no right to participate in any incentive compensation plan
of the Company subsequent to the date of termination; and

                 (f) if it would be illegal to provide the benefits under such
plans, practices, programs or policies referred to in Section 3.1(d) above due
to, among other things, nondiscrimination rules or tax qualification rules
applicable to such plans, practices, programs or policies, then the Company will
be deemed to be in compliance with this Agreement if it provides such Employee
with a comparable substitute therefor, provided the Employee and the Employee's
dependents are placed thereby in the same or a better economic position than if
the Company provided such benefits through its then existing plans, practices,
programs or policies.

         3.2 CAUSE. If the Employee's employment shall be terminated for Cause,
this Agreement shall terminate without further obligations of the Company to the
Employee hereunder.

         3.3 DEATH. If the Employee's employment is terminated by reason
of the Employee's death, this Agreement shall terminate without further
obligations of the Company to the Employee other than those obligations accrued
or earned and vested (if applicable) by the Employee as of the date of death.

Section 4. DISPUTES.

         It is the intent of the parties hereto that the following dispute
resolution procedure shall apply hereunder.

         (a) No payments or benefits need be paid hereunder except upon the
Notice of Termination provided for in Section 2.4 hereof or, if the Company does
not give such a Notice, upon a written application of the Employee or other
person claiming thereunder to the person specified in Section 8(d) hereof,
provided such claim may be made in general terms only specifying the basis for
the claim, and that it is made under this Agreement, without enumerating each
benefit claimed.

         (b) The Company must accept or reject the claim within thirty (30)
days.

<PAGE>   5

         (c) If the Company rejects the claim, it must do so in writing
specifying the reasons therefor.

         (d) If the claimant disagrees with the Company's decision, or if the
Company fails to respond within such thirty (30) day period, appeal shall be to
a court of Competent jurisdiction. Such appeal shall be on a fully de novo basis
and the decision of the Company denying benefits shall not be entitled to any
deference by such court.

Section 5. EXCLUSIVITY OF RIGHTS.

         It is expressly understood and acknowledged by Employee that the
Company's obligations under Section 3 of this Agreement shall be in lieu of any
obligation on the part of the Company for payment of severance, salary,
incentive compensation, auto allowance, health and retirement benefits
(collectively, the "Severance Benefits") under any other Company plan, policy or
agreement (including but not limited to, the Non-Competition Agreement between
Company and Employee, and the Company's severance policy) in the event of
termination of Employee's employment with the Company during the Change in
Control Period. Accordingly, the Employee acknowledges that he/she shall not be
entitled to Severance Benefits other than those set forth in Section 3, and
understands that his/her exclusive entitlement to Severance Benefits during the
Change in Control Period shall be as set forth in Section 3.

         Except as provided in the foregoing paragraph of Section 5 hereof, and
subject thereto: (1) Nothing in this Agreement shall prevent or limit the
Employee's continuing or future participation in any benefit, bonus, incentive
or other plans, programs, policies or practices provided by the Company or any
of its Subsidiaries and for which the Employee may qualify, nor shall anything
herein limit or otherwise affect such rights as the Employee may have under any
stock option agreements with the Company or any of its Subsidiaries; (2) Amounts
which are vested benefits under any plan, policy, practice or program of the
Company or any of its Subsidiaries at or subsequent to the date of termination
shall be payable in accordance with such plan, policy, practice or program; and
(3) Employee shall be entitled to participate in any other plan, practice,
program or policy of either the Company or any successor to the Company referred
to in Section 7 hereof under which the Employee is entitled to participate by
law or by reason of being vested under such plan, practice, program or policy.

Section 6. FULL SETTLEMENT.

         Except as provided in this Section 6, the Company's obligation to make
the payments provided for in this Agreement and otherwise to perform its
obligations hereunder shall not be affected by any set-off, counterclaim,
recoupment, defense or other claim, right or action which the Company may have
against the Employee. In no event shall the Employee be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Employee under any of the provisions of this Agreement, nor shall any
amounts actually paid to the Employee by any person for services rendered prior
or subsequent to the date of termination reduce the Company's payment
obligations under Section 3.1 hereof. The Company agrees to pay, to the full
extent permitted by law, all legal fees and expenses which the Employee may
reasonably incur as a result of any contest (regardless of the outcome thereof)
by the Company or others of the validity or enforceability of, or liability
under, any provision of this Agreement, plus in each case interest at the
applicable Federal rate provided for in Section 7872(f)(2) of the Code.

Section 7. SUCCESSORS.

         (a) This Agreement is personal to the Employee and without the prior
written consent of the Company shall not be assignable by the Employee. This
Agreement shall inure to the benefit of and be enforceable by the Employee's
legal representatives.

the business and/or assets of the Company to assume expressly and agree to

Company would be required to perform it if no such succession had taken place.

defined and any successor to its business and/or assets as aforesaid which
assumes this Agreement by operation of law, or otherwise.

                  "Notwithstanding anything to the contrary contained herein,
                  (x) Prime Rate Loans consisting of Bridge Loans shall not be
                  eligible for conversion to Eurodollar Rate Loans and (y)
                  Lender and Reference Bank shall not be required to purchase
                  United States Dollar deposits in the London interbank market
                  or other applicable Eurodollar Rate market to fund any
                  Eurodollar Rate Loans, but the provisions hereof shall be
                  deemed to apply as if Lender and Reference Bank had purchased
                  such deposits to fund the Eurodollar Rate Loans."
