- -----------------------------------------------------------

                           KEITHLEY INSTRUMENTS, INC.
                   1996 OUTSIDE DIRECTORS DEFERRED STOCK PLAN


                  Keithley Instruments, Inc. (the "Company") hereby establishes
the Keithley Instruments, Inc. 1996 Outside Directors Deferred Stock Plan,
effective as of February 10, 1996 (the "Plan").

                  The Plan is established for the purposes of deferring outside
directors' fees and paying those fees in the form of no par value Common Shares
of Keithley Instruments, Inc. ("Shares").

                  The Plan is intended not to be subject to the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), is intended to be
an unfunded plan of deferred compensation for purposes of the Internal Revenue
Code of 1986, as amended (the "Code"), and is intended not to satisfy any
qualification requirements of Section 401 of the Code.

                                    ARTICLE 1

                                ----------------

1.1      Method of Deferral.
         -------------------

         Each outside director may elect to defer receipt of all or a portion
         (but not less than 50%) of the director's fees payable to such director
         in respect of a given calendar year, by signing a deferral agreement
         and delivering it to the Committee on or before the July 31st next
         preceding the calendar year for which such director's fees are earned
         and otherwise become payable. For Plan purposes, the term "director's
         fees" shall include all meetings fees (including committee and special
         meetings fees), but shall not include any paid or reimbursed expenses.
         In each Deferral Agreement, the director (the "Participant") will
         irrevocably elect (i) the percentage of his or her director's fees to
         be deferred, (ii) whether the amount deferred shall take the form of
         Shares or cash; and (iii) subject to Section 2.1 hereof, the date or
         dates on which the deferred cash or Shares shall be distributed.

                                    ARTICLE 2
                                    ---------
                                  DISTRIBUTIONS
                                  -------------

2.1      Date of Distribution.
         ---------------------

         The balance of the Deferral Account of a Participant shall be
         distributed to the Participant or, in the event of the death of the
         Participant, the person designated by the Participant as beneficiary
         (the "Beneficiary") within thirty (30) days following (a) the later of
         (i) the date the Participant terminates his or her service on the Board
         of Directors of the Company; or (ii) the date elected by the
         Participant in the Deferral Agreement (which shall not be less than
         five (5) years following the year in which such fees are earned); or
         (b) if earlier than the date specified in part (a) hereof, the date
         such Participant dies.

2.2      Method of Distribution.
         -----------------------

         Each distribution of the balance of a Deferral Account shall be paid in
         a single sum or Share certificate or, if elected by the Participant in
         the Deferral Agreement, in installments.

2.3      Amount of Distribution.
         -----------------------

         The amount of any single sum payment or distribution shall be equal to
         the balance of the Deferral Account or, in the case of a distribution
         of Shares, the number of whole Shares credited to such Account (any
         fractional interest to be paid in cash). The amount of each installment
         payment shall be equal to the balance of the Deferral Account
         multiplied by a fraction, the numerator of which is one and the
         denominator of which is the number of installments remaining.
         Installment distributions to be made in the form of Shares shall be
         rounded to the nearest whole Share.

                                    ARTICLE 3

                                    --------

3.1      Establishment of Deferral Account.
         ----------------------------------

         The Committee shall establish a Deferral Account in the name of each
         Participant. Such Account shall be established as of the first date
         that such director's fees otherwise would have been paid to such
         Participant. Each Deferral Account shall be credited with the deferred
         portion of such director's fees.

3.2      Investment of Account.
         ----------------------

         All credits to a Deferral Account of a Participant shall be deemed to
         be invested in Shares or an interest-bearing account, as such
         Participant shall elect. The number of Shares credited to a
         Participant's Deferral Account by virtue of such Participant's election
         to invest in Shares shall determined by reference to that number of
         whole Shares actually purchased in the open market by the Agent
         determined in accordance with Article 5 hereof, based on the funds
         provided to the agent as a result of such Participant's election;
         provided that such deemed investment in Shares shall be credited based
         on such Agent's purchase activities without discriminating in favor of
         or against any individual Participant; and provided further, that a
         Participant shall at all times have only a contractual right to receive
         cash and/or Shares in the future, and shall not acquire any beneficial
         ownership interest in, or have any control over, any Shares actually
         acquired or held by such Agent. Any amount of Deferral otherwise
         elected by a Participant to be invested in Shares and not credited as
         whole Shares shall be credited with interest in accordance with Section
         4.2 hereof, until capable of being used to purchase whole Shares.

3.3      Nature of Accounts.
         -------------------

         All credits to a Deferral Account of a Participant shall be recorded as
         an obligation of the Company on its books and records. However, no
         Participant or Beneficiary shall have any proprietary rights of any
         nature with respect to any Account of any Participant or with respect
         to any funds, securities or other property owned by the Company or any
         third party beneficially for the Company. All payments and
         distributions made or due under the Plan shall be made from the
         Company's general funds, or from funds or other sources in which the
         Company has a beneficial interest. In no event shall any Participant or
         Beneficiary have any claim or right to any payment or any distribution
         of property hereunder that is superior to any claims or rights of any
         general unsecured creditor of the Company.

                                    ARTICLE 4

                                ----------------

4.1      Investment Elections.
         ---------------------

         Each Participant shall make an investment election in the manner
         prescribed by the Committee, directing the manner in which his/her
         Deferrals shall be deemed to be invested. Each investment election must
         be made at the time the applicable Deferral Agreement is signed and may
         not be revoked or changed. Each Participant may make a separate
         investment election for each of his/her Deferral Accounts. Each
         investment election shall specify that Deferrals shall be deemed to
         either be invested in Shares or deposited in an account bearing
         interest at the prime rate. For this purpose, "prime rate" means the
         stated annual interest rate established by Society National Bank or its
         direct successor ("Society") from time to time as its prime or base
         rate, whether or not publicly announced and without regard to whether
         such rate is Society's most borrower-favorable or best interest rate.
         Subject to any minimum or maximum rate limitations specified by
         applicable law, the prime rate will automatically and immediately
         change from time to time effective as of the effective date of each
         such change in the prime rate.



4.2      Nature of Investment Funds.
         ---------------------------

         Notwithstanding any contrary provision in the Plan, or in any trust or
         agency relationship established by the Company or the Committee (or to
         which the Company or the Committee is or are parties), or in any
         Deferral Agreement, each Deferral Account is a mere unsecured promise
         by the Company to make payments in the future and no Participant shall
         have any right or interest in any particular funds, securities or
         property of the Company, or any trust or escrow.

                                    THE AGENT
                                    ---------

5.1      Appointment, Replacement of Agent.
         ----------------------------------

         The Committee shall select and appoint an agent with limited authority
         to act on its behalf and for and on behalf of the Plan, with respect to
         the purchase, holding and accumulation of Shares (the "Agent"). The
         Agent shall serve at the pleasure of the Committee and may resign, or
         be removed by the Committee, upon the giving of thirty (30) days prior
         written notice (which may be waived by mutual written consent of the
         Committee and the then-incumbent Agent). The Company shall promptly
         transfer to and deposit with the Agent cash in an amount equal to the
         deferrals made by participating directors under the Plan. A party shall
         not be precluded from serving as Agent merely because such party (or an
         affiliate thereof) otherwise represents or provides services for the
         Company, or is (or at any time functions as) a "market maker" in the
         Shares of the Company; provided, that all Shares acquired by the Agent
         in connection with the Plan shall be acquired strictly in accordance
         with Section 5.2 hereof, and shall in no event be acquired by the Agent
         from Shares then held by the Agent for its own account.

5.2      Rights, Duties and Responsibilities of Agent.
         ---------------------------------------------

         The Agent shall have the following rights, duties and responsibilities,
         in addition to any other duties and responsibilities specified by the
         Committee in any written agency agreement to which the Agent is a
         party:

         (a)      Acting at its discretion with respect to timing, price and
                  broker or dealer, the Agent shall acquire by purchase Shares
                  in the open market, using any amounts actually received from
                  the Company in respect of deferrals made under the Plan or in
                  respect of any Shares held by the Agent, but in no event
                  buying or trading "on margin" or buying Shares from its own
                  account;

         (b)      Promptly voting or otherwise exercising all rights capable of
                  being exercised by record-holders of Shares;

         (c)      Surrendering, delivering, tendering or transferring Shares, as
                  and when directed by the Committee, to such persons or parties
                  as the Committee may in writing designate; and

         (d)      Maintaining an appropriate record of all transactions
                  involving Shares, or any amounts directly or indirectly
                  received from the Company;

         provided, that the Agent shall not discriminate or differentiate as
         between individual participants with respect to the timing and purchase
         of Shares.

5.3      Status of Shares, Other Property.
         ---------------------------------

         Any Shares or other property held by the Agent, including any earnings,
         income or accretions on such Shares or other property, shall be held by
         the Agent and used exclusively for the uses and purposes of the
         Participants (and their Beneficiaries) and the general creditors of the
         Company; however, Participants and their Beneficiaries shall have no
         preferred claim on, or any beneficial ownership interest in, any Shares
         or other property directly or indirectly received, acquired or held by
         the Agent. Any rights created under the Plan and any related agency
         agreement shall be mere unsecured contractual rights of Participants
         and their Beneficiaries against the Company. Any assets held by or on
         behalf of the Agent will be subject to the claims of the Company's
         general creditors, as determined under all relevant federal and state
         law. The Company shall pay directly, or reimburse the Agent for, any
         and all taxes and related expenses due in respect of any income or
         gains on assets held or acquired by the Agent.

                  as may be desirable to assist in administering the Plan, and
                  provide for the payment and appropriate indemnification by the
                  Company of such parties;

         (g)      to exercise the other powers that are expressly granted to it

                  that are impliedly necessary for it to carry out any of its

         The existence of the Plan shall not create, evidence or change any
         contract for continuing service, or any continuing right to hold
         office, of any Participant. The right of the Company, or its
         shareholders, to take any action with respect to a director, including

         pledge, encumbrances (as security or otherwise), attachment,
         garnishment, levy, execution, or other legal or equitable process by
         creditors of the Participant or Beneficiary, and no Participant or
         Beneficiary shall have the power at any time or in any manner to
         anticipate, transfer, assign (either at law or in equity), alienate, or
         subject to attachment, garnishment, levy, execution or other legal or
         equitable process, or in any way encumber, such Participant's or
         Beneficiary's rights or interests under the Plan, and any attempt to do
         so shall be void; provided, however, that the Company shall have the
         unrestricted right to set off against or recover out of any payments or
         property due a Participant or Beneficiary at the time such payments or
         property would have otherwise been payable hereunder, any amounts owed
         the Company by such Participant or Beneficiary.

         -----------------------

         Any payment to any Participant or Beneficiary in accordance with the
         terms of the Plan shall, to the extent thereof, be in full satisfaction
         of all claims hereunder, whether they be against the Company, the
         Committee, or the Agent, any of whom may require the Participant or
         Beneficiary (or legal representative), as a condition precedent to such
         payment, to execute a release and receipt therefor.

7.7      No Liability.
         -------------

         Participation in the Plan is entirely at the risk of each Participant.
         Neither the Company, the Committee, the Agent, nor any other person
         associated with the Plan shall have any liability for any loss or
         diminution in the value of Deferral Accounts, or for any failure of the
         Plan to effectively defer recognition of income or to achieve any
         Participant's desired tax treatment or financial results.

7.8      Shares Subject to the Plan.
         ---------------------------

         The maximum dollar amount of Shares that may be acquired by the Plan
         during any calendar year shall not exceed the aggregate directors' fees
         eligible to be deferred hereunder by all those persons then eligible to
         become Participants hereunder. Any Shares acquired by the Plan may
         consist, in whole or part, of authorized and unissued shares or
         treasury shares, or Shares purchased in the open market by or on behalf
         of the Agent from cash or property then held thereby. If there is a
         merger, reorganization, consolidation, recapitalization, share
         dividend, share split, combination of shares or other change in
         corporate structure of the Company affecting the Shares, such
         substitution or adjustment shall be made in the aggregate number of
         Shares held for distribution under the Plan as may be approved by the
         Committee in its sole discretion; provided that the number of Shares to
         be issued and distributed under the Plan shall always be a whole
         number. Any fractional Shares shall be eliminated and the value of such
         fractional Shares shall be deemed to have been transferred to the
         interest-bearing account as of the effective date of such substitution
         or adjustment.

7.9      Conditions to Effectiveness of Plan.
         ------------------------------------

         Notwithstanding anything in this Plan, any Deferral Agreement or any
         agency agreement to the contrary, the effectiveness of the Plan, any
         Deferral Agreements, and any agency agreement shall be conditioned on
         the Plan being approved by the Company's shareholders

         Plan, all Deferral Agreements, and any agency agreement, shall be
         considered void ab initio and all fees and other amounts previously
         deferred pursuant to those Deferral Agreements shall be paid forthwith
         to the appropriate Participants, as if the relevant Deferral Agreements
         had never existed.

be executed by its duly authorized officers as of this 11th day of December,

                               DEFERRAL AGREEMENT

         THIS DEFERRAL AGREEMENT is entered into pursuant to the provisions of
Keithley Instruments, Inc. 1996 Outside Directors Deferred Compensation Plan
("Plan"). All capitalized terms in this Agreement shall have the meanings
ascribed to them in the Plan.

1.       DEFERRAL ELECTION. I hereby elect to defer receipt of the following
         portion of my directors' fees (including all meetings fees, but not
         paid or reimbursed expenses) earned in respect of the period commencing
         January 1, _____ (enter any desired percentage not less than 50%):

         ___  I elect to defer ______% of my director's fees.

2.       Deferral Period. (The Plan gives you the option of electing a Deferral
         Period, the balance of your Deferral Account established pursuant to
         this Agreement will be distributed to you within 30 days after the end
         of the Deferral Period (minimum, 5 years), or, if later, the date of
         cessation of service as a director of Keithley Instruments, Inc. (the
         "Company") (unless you die, in which case distribution will be made to
         your Beneficiary shortly following your date of death). If you do not
         elect a Deferral Period, your Account will be distributed within 30
         days of the date of your cessation of service as a director of the
         Company, subject only to the special rule noted above in cases where
         death occurs prior to distribution.)

         Please check one of the following:

         ___  I elect a Deferral Period ending on ___________ (Must be a date at
              least 5 years after the close of the calendar year in which the
              director's fees are earned)

                                       OR

         ___  I do NOT wish to elect a Deferral Period.

3.       METHOD OF DISTRIBUTION. I hereby elect distribution of the balance of
         the Deferral Account established pursuant to this Agreement: (check
         one)

         ___  in a single sum payment

                                       OR

         in _______ annual installments

4.       INVESTMENT ELECTION. I direct that the amount I have deferred pursuant
         to Section 1 of this Agreement shall be deemed to be invested as
         follows, in the percentages indicated: (must be increments of 1%)

         Shares (in whole Shares)                               ______%
         Cash with interest (prime rate,
                           as specified in Plan)                ______%

         I understand that this investment election cannot be changed. I also
         understand that this investment election is merely a device used to
         determine the amount payable to me under the Plan and does not provide
         me with any actual rights or interests in any particular funds,
         securities or property of the Company, or any property or assets held
         by any agent of the Company or the Committee, or in any Shares of
         Keithley Instruments, Inc. I also understand that my right to receive
         distributions under the Plan makes me a general unsecured creditor of
         the Company with no greater priority than any other general unsecured
         creditor of the Company.

5.       BENEFICIARY: In the event of my death, I designate the following
         individual or entity as beneficiary to receive the balance of my
         Deferral Account:

                         _________________
                         _________________
                         _________________


6.       MISCELLANEOUS. I understand that all elections made in this Agreement
         are irrevocable and that this Agreement is subject to the terms,
         conditions and limitations of the Plan, as in effect from time to time,
         in all respects. I agree to accept as final and binding all decisions
         and interpretations of the Committee relating to the Plan and this
         Agreement.
