PROXY STATEMENT

ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON FEBRUARY 9, 2008

GENERAL INFORMATION

This Proxy Statement is furnished in connection with the solicitation of proxies by and on behalf of the Board of Directors of Keithley Instruments, Inc. (the “Company”) for use at the Annual Meeting of Shareholders of the Company to be held on February 9, 2008, and any adjournment or postponement thereof. The time, place and purposes of the Annual Meeting are stated in the Notice of Annual Meeting of Shareholders which accompanies this Proxy Statement.

The solicitation of proxies is made by and on behalf of the Board of Directors. The expense of soliciting proxies, including the cost of preparing, assembling and mailing the proxy materials, will be borne by the Company. In addition to solicitation of proxies by mail, solicitation may be made personally and by telephone, and the Company may pay persons holding shares for others their expenses for sending proxy materials to their principals. No solicitation will be made other than by Directors, officers and employees of the Company.

The presence of a shareholder at the Annual Meeting will not operate to revoke the shareholder’s proxy. Any shareholder giving a proxy pursuant to this solicitation may revoke it by giving notice to the Company in writing or in open meeting. All properly executed proxies received by the Board of Directors of the Company pursuant to this solicitation will be voted at the Annual Meeting, in accordance with the directions contained in such proxies. If no directions are given, properly executed proxies will be voted FOR the election of the nominees named in this Proxy Statement and FOR the proposals set forth in the Notice, with discretionary authority to vote on all other matters that may properly come before the Annual Meeting or any adjournment or postponement thereof.

The close of business on December 11, 2007 has been fixed as the record date for the determination of shareholders entitled to notice of and to vote at the Annual Meeting. This Proxy Statement and the accompanying President’s letter, notice and proxy, together with the Company’s annual report to shareholders for the fiscal year ended September 30, 2007, are first being sent to shareholders on or about December 28, 2007.

VOTING RIGHTS

As of the close of business on December 11, 2007, there were outstanding 13,859,921 Common Shares, without par value, of the Company (“Common Shares”) and 2,150,502 Class B Common Shares, without par value, of the Company (“Class B Common Shares”). The holders of outstanding Common Shares on that date will be entitled to one vote for each share held, and the holders of outstanding Class B Common Shares on that date will be entitled to ten votes for each share held. Proxies received by the Company but marked as abstentions or broker non-votes will not count in favor of, or against, election of a nominee for Director; however, abstentions and broker non-votes will have the effect of a vote against approval of the proposals relating to the Code of Regulations.

The Ohio Revised Code, as it applies to the Company, provides that if notice in writing is given by any shareholder to the President, a Vice President or the Secretary of the Company not less than 48 hours before the time fixed for holding the meeting that such shareholder desires the voting to elect Directors to be cumulative, and if an announcement of the giving of such notice is made upon the convening of the meeting by the Chairman or the Secretary or by or on behalf of the shareholder giving such notice, then each shareholder shall have cumulative voting rights in the election of Directors, enabling such shareholder to give one nominee for Director as many votes as is equal to the number of Directors to be elected multiplied by the number of shares in respect of which such shareholder is voting, or to distribute votes on the same principle among two or more nominees, as such shareholder sees fit. If cumulative voting is in effect, the persons named in the proxy will vote shares represented thereby so as to elect as many of the ten nominees named herein as possible.

PROPOSAL ONE: ELECTION OF DIRECTORS

At the Annual Meeting, or any adjournment or postponement thereof, Common Shares and Class B Common Shares represented by proxies, unless otherwise specified, will be voted for the election as Directors of the ten persons named below who have been nominated by the Board of Directors following the recommendation of the Board’s Nominating and Corporate Governance Committee.

Each of the Directors to be elected at the meeting is to serve until the next Annual Meeting and until his or her successor shall have been duly elected and qualified. Pursuant to the Company’s Amended Articles of Incorporation, one-fourth (calculated to the nearest whole number) of the number of authorized Directors, which equals three Directors, is entitled to be elected by the Common Shares voting separately as a class. Messrs. Bachman, Jackman and Reddy have been nominated as the Directors to be so elected by the holders of the Common Shares of the Company. The remaining seven nominees are to be elected by the holders of the Common Shares and the Class B Common Shares voting together. The three nominees receiving the greatest number of votes of the Common Shares voting separately as a class, and the seven other nominees receiving the greatest number of votes of the Common Shares and the Class B Common Shares voting together without regard to class, will be elected as Directors.

Each of the nominees is presently a member of the Board of Directors and each has indicated his or her willingness to serve as a Director, if elected. If any nominee at the time of election is unable or unwilling to serve or is otherwise unavailable for election (which contingency is not now contemplated or foreseen), it is intended that the shares represented by proxies will be voted for the election of any substitute nominee that may be named by the Board of Directors.

The Compensation and Human Resources Committee (the “Compensation Committee”) responsibilities are to review and approve the goals and objectives relevant to the compensation of the Company’s Chief Executive Officer, other executive officers and other employees who report to the Company’s Chief Executive Officer, and to amend these goals and objectives if the Compensation Committee deems it appropriate.

Over the past year, the consultant has, at the direction of the Compensation Committee, provided information and advice on a range of subjects as described under the caption “Executive Compensation and Related Information — Compensation Discussion and Analysis.”

The Chief Executive Officer, Chief Operating Officer and Vice President, Human Resources, attend Compensation Committee meeting by invitation to provide input with respect to compensation and performance assessments of executive officers. Consistent with the equity award grant policy adopted by the Board of Directors, the Compensation Committee delegates to the Chief Executive Officer authority to grant a limited number of equity awards as further described under “Executive Compensation and Related Information — Compensation Discussion and Analysis — Equity Award Granting Practices.”

The Strategy Committee is responsible for ensuring that management has in place strategies and action plans as well as useful planning and control systems to enable the Company to meet its objectives.

The Nominating and Corporate Governance Committee is responsible for assisting the Board of Directors in identifying individuals qualified to become Board members; to recommend board committee structure, membership and operations; to develop and recommend to the Board a set of effective corporate governance policies and procedures; and to lead the Board in its annual review of the Board’s performance.

The charter of the Nominating and Corporate Governance Committee provides that the Committee shall make recommendations to the Board regarding director nominations, including director candidates recommended by shareholders. If a shareholders wishes to recommend a candidate, they should send their recommendation, with a description of the candidate’s qualifications, to: Chairman, Nominating and Corporate Governance Committee, c/o Marcia Miller, Keithley Instruments, Inc., 28775 Aurora Road, Cleveland, Ohio 44139. The Committee has not established specific minimum qualifications a candidate must have in order to be recommended by the Committee. However, in determining qualifications for new directors, the Committee will periodically establish and review Board succession plans, establish the experience and attributes needed to fulfill its responsibilities and work with

9

the Chief Executive Officer to identify management’s needs for advice and counsel. A director candidate pool will be established from recommendations from shareholders and the Board of Directors. Additionally, the Nominating and Governance Committee may retain a board search consultant to identify and recruit potential directors.

DIRECTOR COMPENSATION

In 2005, the Compensation Committee undertook a reassessment of the Board’s director compensation practices in recognition of the increased expectations and responsibilities faced by directors of public companies following adoption of the Sarbanes-Oxley Act, new regulatory and stock exchange requirements and director compensation trends at comparable high-technology public companies. In determining director compensation, the Compensation Committee reviewed data of 21 peer companies as well as other broad-based industry survey data. Based on their research and advice of the consultants retained by and reporting to the Compensation Committee, the Compensation Committee recommended, and the Board of Directors approved, a revised director compensation program, which began to take effect in fiscal year 2006.

For fiscal year 2007, Directors who are not employees of the Company received an annual fee of $20,000 paid in four installments. Directors received an additional $1,000 for each board meeting attended and each committee meeting attended, except for Audit Committee meetings for which each Director received $1,500 for his or her attendance. The Audit Committee Chairman received an additional annual fee of $10,000 paid in four installments, while the Compensation and Human Resources Committee Chairman, the Strategy Committee Chairman, and the Nominating and Corporate Governance Committee Chairmen each received an additional annual fee of $5,000 paid in four installments. Additionally, in August 2006, the Board of Directors appointed a Special Committee of the Board to investigate the Company’s stock option practices. In February 2007, the Board of Directors approved fees to be paid to committee members of $1,500 per meeting for all past and future meetings, and a one-time retainer fee of $10,000 to be paid to the Chair of the Special Committee.

Directors may defer their fees under the Keithley Instruments, Inc. 1996 Outside Directors Deferred Stock Plan. Under the terms of that Plan, the fees are invested in Common Shares, the total number of which are included in Security Ownership of Management table found on page 3, and will be paid out in cash or Common Shares on a specified date or upon retirement from the Board of Directors per the election of the recipient. In addition, Directors may defer fees under the Keithley Instruments, Inc. Deferred Compensation Plan. Under this Plan, the amounts deferred earn interest based on a prime rate formula specified in the Plan.

Along with shifting employee compensation from a focus on stock options to full-value shares, the equity compensation of the Board has also been modified. Each non-employee Director will receive a restricted stock award worth $75,000, rounded to whole shares, upon his or her initial appointment to the Board. The shares will vest over a 3-year period. Additionally, each non-employee Director receives an annual Common Share grant equal to approximately $58,000 issued in four installments. The shares are issued pursuant to the Keithley Instruments Inc. 2002 Stock Incentive Plan. Effective October 1, 2005, the Board of Directors established a policy requiring Directors to own $100,000 of Common Shares in the Company (including shares held in the deferred compensation plan). It is expected that the Company’s Directors achieve this ownership level within four years of the establishment of the policy, or in the case of new Directors, within four year’s of their election. With the exception of one director elected less than four years ago, all of the directors have met this policy.

The following table summarizes the compensation received by each Director during fiscal year 2007:

(4)	Mr. White has deferred his fees in the Keithley Instruments, Inc. Deferred Compensation Plan.

The Company reimburses Directors for their reasonable expenses associated with attending Board meetings and provides them with liability insurance coverage for their activities as Directors.

Under the Company’s Articles of Incorporation and Code of Regulations, the Directors are entitled to indemnification from Keithley to the fullest extent permitted by Ohio corporate law. The Company has entered into indemnification agreements with each of the Directors. The agreements to not increase or decrease the scope of the indemnification provided by set forth processes and procedures for indemnification claims.

Beginning in fiscal year 2008, non-employee Directors’ fees will be paid solely on a retainer-based structure versus a combination of retainer and meeting attendance fees. While the structure has changed, it is anticipated that there will be no material increase to the total compensation that an individual Director shall receive. This change was implemented so that fees would not limit Board of Director involvement in important corporate matters.

CODE OF ETHICS

The Company has a Code of Ethics that applies to all employees, executive officers and Directors of the Company, including the Company’s principal executive officer, principal financial officer and principal accounting officer. The Code of Ethics includes provisions covering compliance with laws and regulations, insider trading practices, conflicts of interest, confidentiality, protection and proper use of Company assets, accounting and recordkeeping, fair competition and fair dealing, business gifts and entertainment, payments to government personnel, and the reporting of illegal or unethical behavior. The Code of Ethics is posted on the Company’s website and is available in print to any shareholder submitting a request to the Company c/o Marcia Miller, Keithley Instruments, Inc., 28775 Aurora Road, Cleveland, Ohio 44139. Any waiver of any provision of the code granted to an executive officer or Director may only be made by the Board of Directors or a Committee of the Board authorized to do so and will be promptly disclosed on the Company’s website at www.keithley.com.

EXECUTIVE COMPENSATION AND RELATED INFORMATION

Compensation Discussion and Analysis

The following describes the material elements of the Company’s compensation objectives and policies and the application of these objectives and policies to the Company’s executive officers, particularly the individuals named in the Summary Compensation Table on page 20. The rules regarding disclosure of executive compensation in proxy statements were modified significantly in 2006. This is our first proxy statement to which the new rules apply. Accordingly, the information in this proxy statement is not directly comparable to the information disclosed in prior years.

Executive Compensation Governance

The Compensation and Human Resources Committee (the “Committee”) of the Board of Directors is responsible for reviewing and approving executive management compensation and for evaluating the Chief Executive Officer’s performance. These responsibilities and other governance matters concerning the Committee are described under the caption “Corporate Governance.”

The Committee receives assistance and advice from its executive compensation consultants, Radford Survey + Consulting (“Radford”), a human resources consulting firm. Radford reports directly to the Chairperson of the Committee, although its representatives also provide advice and discuss executive compensation issues directly with management. In the past year, Radford has, at the direction of the Committee, provided information and advice on a range of subjects, including peer group definition, market data, compensation levels for officers and the Board of Directors, equity grants (both amount and grant terms) and stock ownership guidelines. The Committee has available to it relevant data and information regarding all elements of compensation as it makes its decisions regarding each element of compensation for the named executive officers.

Executive Compensation Philosophy

The goal of Keithley’s compensation program is to attract highly qualified individuals, and to retain and motivate them to achieve superior financial results for the Company in both the short-term and long-term. The compensation program is designed to reward the achievement of sales growth, quality of earnings and appreciation of the Company’s share price. The Committee believes that our compensation program and specific compensation decisions regarding our executive officers must meet two standards. First, our compensation program must be competitive with companies that are our direct competitors in test and measurement as well as a broader group of electronics companies with whom we compete for employees. Second, our compensation program and decisions must be designed to lead to the creation of shareholder value through future share appreciation. In addition, compensation decisions regarding specific individuals are impacted by individual job performance, Company performance, and significant changes in the competitive landscape for individuals possessing the skills we require.

Our executive compensation program has four main components: base salary, annual cash bonus, long-term incentive awards in the form of stock compensation, and health and welfare benefits which are discussed in more detail below. All four components are targeted at median levels for the executive’s position based on a survey of peer group companies and two-broadly-based compensation surveys as described more fully below. The Committee targets our executives’ compensation at the market median because it believes the median ensures that our compensation program is sufficiently competitive to attract and retain talented executives and maintain external pay equity. However, the Company’s incentive award programs are designed to pay above the median for above target performance and below the median for performance that is low relative to peers.

The Committee allocates total compensation between currently paid cash compensation and long-term compensation. The allocation between currently paid cash compensation and long-term compensation for Mr. Keithley, our Chief Executive Officer, and for Ms. Rae, our Chief Operating Officer, is targeted at approximately a 50/50 split. The allocation for other executive officers is targeted between 60/40 and 70/30. These allocations are based on market competitiveness and the Committee’s assessment of the impact that it believes each executive officer has on execution of the Company’s long-term strategy.

12

Executive Compensation Methodologies

The Committee assembles, with the assistance of Radford, competitive market information about executive compensation from an annual review of companies included in a peer group, other competitive market compensation information, executive compensation trends, our business needs, and our financial performance compared to peers. The Committee reviews this competitive information together with performance assessments of our executives and recommendations provided by the CEO and COO (with the exception of Mr. Keithley for which no recommendation is made and Ms. Rae whose recommendation is made solely by the CEO). Generally, the Committee sets executive officers’ salary to fall within a range of +/- 20% of the median of surveyed companies, target bonus (as a percentage of salary) at approximately median, long-term compensation award value is targeted at median, but actual target awards are constrained by corporate burn rate as well, so that based on the Company’s valuation relative to peers, periodically long-term compensation target awards are below median. If the Company has exceptional performance, it is possible that actual total compensation could exceed the median for total compensation for the surveyed companies in a given year. For fiscal 2007, based on Company performance, total compensation for all of the named executive officers was at or below the market median.

In determining what it believes to be market median for executive positions, the Committee obtains information from Radford regarding competitive market compensation data available from the proxy statements of peer group companies selected by the Committee and from two broad-based electronics industry surveys. The peer group for 2007 consists of 21 publicly traded corporations that are headquartered in the United States with whom we compete for employees with similar skills. The Committee reviews the peer group each year to ensure that it continues to be comprised of companies appropriate for purposes of comparison. As compensation was set in the Fall of 2006, the following companies comprised this peer group:

•   ADE Corporation	•   Aeroflex, Inc.
•   Analogic Corporation	•   Brooks Automation, Inc.
•   Cascade Microtech, Inc.	•   Credence Systems Corporation
•   Electro Scientific Industries, Inc.	•   Electroglas, Inc.
•   EXFO Electro Optical Engineering, Inc	•   Kulicke & Soffa Industries
•   LeCroy Corporation	•   LTX Corporation
•   National Instruments Corporation	•   Newport Corporation
•   Photon Dynamics, Inc.	•   Rudolph Technologies, Inc.
•   Therma-Wave, Inc.	•   Tollgrade Communications, Inc.
•   Varian Semiconductor Equipment	•   Veeco Instruments, Inc.
•   X-Rite, Inc.

In addition, Radford supplemented the peer group data with data from two broad-based surveys covering companies in the electronics industry with revenue generally between $50 and $250 million to calculate a median consisting of a blended average of the two broad-based surveys and data from the peer group. The Committee uses the blended average to minimize the impact of any outlaying data points and because, in certain circumstances, the companies in the peer group do not have proxy data for similarly situated executive positions that can be used for comparison to one or more of our executives.

Our management works with Radford to make specific recommendations to the Committee with regard to compensation based upon the market data and management’s assessment of the performance of each individual executive officer (other than the CEO). For the CEO, the Committee conducts the performance assessment. Compensation amounts realized from past years and prior year equity awards are generally not considered in the current year’s determination of each individual’s compensation package. The impacts of tax or accounting treatments for particular forms of compensation also are generally not considered, except to the extent they reflect industry norms.

All salary changes for executive officers are made effective each January 1. Base pay levels and long-term incentive awards are generally determined and approved near the end of the calendar year at a regularly scheduled Committee meeting. The date is determined well in advance and generally occurs at the same time each year (in November) in connection with regularly scheduled Board and Committee meetings. For fiscal year 2007, annual bonus targets were set at the regularly scheduled August 2006 Committee meeting and payout amounts for the annual cash bonus were determined in October 2007 after the fiscal year-end financial results were available. Beginning with fiscal year 2008, preliminary annual bonus targets were reviewed at the regularly scheduled Committee meeting held in August 2007, and final annual bonus targets were reviewed and approved at a regularly scheduled telephonic September meeting. To date,

13

the Committee has not been required to make any final payout determinations with respect to long-term incentive awards because no applicable performance period has been completed.

Elements of Executive Compensation

The Company’s executive compensation program provides the Named Executive Officers with the elements of compensation described below.

Base Salary

Executive officers’ base salaries are benchmarked against the market median of the proxy data and the surveys discussed above. In general, for those executive officers who are not new to their positions and who are performing well, their salaries are targeted to the market median. All executive officers’ salaries are within a range of plus or minus twenty percent of the market median based on individual experience and performance. With the exception of Mr. Keithley and Mr. Plush, all named executive officers received salary increases during fiscal year 2007 ranging from 3.8% to 4.4% based upon individual performances and to ensure the Company’s compensation remained competitive with market movements for individuals with similar skills and experience in similar industries. Because of the costs and management time incurred by the Company in connection with the stock options investigation in 2006, the Committee determined not to increase the base salary of Mr. Keithley or Mr. Plush for fiscal year 2007.

The following table sets forth the base salary and the percentage increase for each named executive officer for fiscal 2007.

			%Increase Over
Named Executive Officer	Annual Base Salary		2006 Base Salary
Joseph P. Keithley	$	425,184		0	%
Mark J. Plush	$	255,589		0	%
Linda C. Rae	$	275,015		3.8	%
John A. Pesec	$	239,000		3.9	%
Mark A. Hoersten	$	214,000		4.4	%
Larry L. Pendergrass	$	214,000		4.4	%

Annual Bonus Program

The Committee determines target bonus awards, which are expressed as a percentage of base salary, for each executive officer based on the blended average market median discussed above determined by Radford for similar positions. For each executive, the Committee establishes a performance threshold and target and a level at which the executive’s maximum bonus is earned. Awards under the plan are paid based upon actual performance against the pre-established performance objectives for the year approved by the Compensation Committee. No bonus is earned at or below threshold performance. If Company performance is above threshold, payouts are based on a linear progression up to a maximum of three times the target bonus amount established for each executive.

The target bonus amounts are determined by the Committee, but are generally based upon the CEO’s recommendations (other than with respect to his own bonus). For 2007, the Committee established pre-tax ROA and Sales Growth as the two quantitative performance measures for the Annual Bonus Plan, except for Mr. Pesec for whom Order Growth was substituted for Sales Growth in order to maximize his focus on obtaining new orders. Each measure was given equal weighting:

							Individual
Metric	Threshold			Target			Maximum Attained at(1)
ROA		23	%		34	%		~40-45	%
Sales Growth		1	%		10	%		~22	%

(1) The Annual Bonus Plan does not cap the performance measures but rather limits an individual’s payout at three times the target bonus award. The number provided in this column approximates the level at which maximum payout would be capped and, for ROA, is a range because of the interplay between the two measures.

14

•  ROA (defined as Earnings Before Taxes (EBT) excluding non-cash compensation and annual bonus expense and net interest income/expense ¸ average assets employed (accounts receivable + inventories + net property plant and equipment at the end of each month of the fiscal year divided by 12)).

•  Individual Performance Factors: The Committee may adjust the payouts by +/- 50% based on an evaluation of the quality of the performance for both the Company and the individual as recommended by the CEO, with the exception of the CEO whose adjustment, if any, is made solely by the Committee.

The Committee evaluates the performance factors and targets for the Annual Bonus Plan each year. The Committee does not necessarily establish the performance targets based on management’s operating plan, but rather on performance levels that the Committee believes promotes Company growth without sacrificing quality of earnings.

The payments under the Annual Bonus Plan are calculated at the end of each fiscal year and are paid annually in cash unless the employee has made an election to defer. Because the Company’s performance in 2007 was below the thresholds established for the year, no named executive officer received a payout under the Annual Bonus Plan.

The following table shows the Annual Bonus Plan target both as a percentage of salary and as a dollar amount for each named executive officer for 2007; as noted above no payouts were received by any named executive officer in 2007.

	Annual Bonus Plan
Named Executive	Target as a Percentage			Annual Bonus Plan		Annual Bonus Payout
Officer	of Salary			Target ($)		2007 ($)
Joseph P. Keithley		70	%	$	297,628	$	0
Mark J. Plush		45	%	$	115,016	$	0
Linda C. Rae		55	%	$	145,790	$	0
John A. Pesec		45	%	$	103,492	$	0
Mark A. Hoersten		40	%	$	82,018	$	0
Larry L. Pendergrass		40	%	$	81,980	$	0

Long Term Compensation Program

The purpose of the Company’s long-term incentive compensation plan is provide a substantial equity incentive for our executive officers to manage the business for the long-term, complementing the annual bonus that rewards performance in a particular year, and to reward them for the performance of the Company and its common shares over multi-year periods. The Committee awards long-term compensation in the form of annual non-qualified stock option grants, and beginning in fiscal year 2006, performance award units (“PAUs”). The Committee has not established any long-term incentive programs that are settled in cash because the Committee believes that stock settled programs offer better alignment between the interests of our executive officers and our shareholders. The Committee as a general practice does not award restricted stock or restricted stock units to executive officers because they may provide substantial value even if our share price declines. However, the Company uses restricted stock award units selectively for non-officer employees, primarily for retention purposes.

Radford establishes a median dollar value for competitive long-term pay for each executive officer position based on the blended average market median described above. The Committee awards a mix of non-qualified stock options and performance share units with targeted value at or near the market median for each position.

15

The following table shows the median total dollar amount of the long-term compensation as determined by Radford for each executive officer, the actual number of stock options and performance units awarded to each named executive officer in 2007, and the total dollar value of long-term awards granted for fiscal 2007. As noted previously, Mr. Keithley and Mr. Plush did not receive stock options or performance units for fiscal year 2007:

	Median Target

Named Executive	Determined by		Options Awarded in		Performance Units		Incentives Awarded
Officer	Radford		2007		Awarded in 2007		in 2007*
Joseph P. Keithley	$	829,500		0		0	$	0
Mark J. Plush	$	263,800		0		0	$	0
Linda C. Rae	$	362,800		25,000		12,600	$	352,400
John A. Pesec	$	152,300		10,000		7,700	$	178,200
Mark A. Hoersten	$	152,300		8,800		6,750	$	156,452
Larry L. Pendergrass	$	183,400		9,600		7,300	$	169,784

*  For this purpose, performance award units are valued at the share price at the time of the grant, and stock options are valued at the time of the grant, based on a formula provided by Radford and applied by Keithley that represents about half of the stock price at the date of grant, and is not the value the Company uses to expense the stock options under Statement of Financial Accounting Standards No. 123(R) Stock-based Compensation (SFAS 123(R)). This valuation method involves fewer assumptions and is believed by the Committee to be more appropriate for establishing levels of compensation. For additional detail about our equity awards and the accounting for them, see the “Grants of Plan-Based Awards for Fiscal Year 2007” and the “Outstanding Equity Awards at September 30, 2007” tables on pages 21 and 22.

The long-term incentive awards shown in the foregoing table were granted in January of 2007. The Committee awards a mix of options and performance units that reflects the executives’ ability to impact the Company’s execution of its long-term plans. Mr. Keithley and Ms. Rae generally receive a 50-50 split between options and performance units and the other executive officers generally receive a 40-60 split of options and performance units.

Performance units are expressed as a number of shares and are earned over a three-year period, with payout dependent upon:

•  the Company’s three-year sales growth in comparison to sales growth of a pre-defined group of peer companies* over the same period, which for 2007 included:

Aeroflex Inc.	Agilent Technologies, Inc.
Anritsu Corp.	Chroma ATE, Inc.
Lecroy Corp.	National Instruments Corp.
Tektronix, Inc.	Yokogawa Electric Corp.
Advantest Corp.	Credence Systems Corp.
Eagle Test Systems, Inc.	LTX Corp.
Nanometrics, Inc.	Photon Dynamics, Inc.
Rudolph Technologies, inc.	Teradyne, Inc.
Therma-Wave, Inc.	Verigy Ltd.
EXFO Electro Optical Engineering, Inc.	JDS Uniphase Corp.
Tollgrade Communications, Inc.

*  These companies are public companies of all sizes, both domestic and international, included in the peer group because they are either direct competitors in the traditional test and measurement field or in the related automated testing equipment/semiconductor test or communications test fields. The related fields are included in the group to ensure the group is large enough to be significant. Some of the companies used in this group are not used in the peer group used for compensation purposes, either because their revenue size is significantly larger than the Company or because they are internationally based and no compensation proxy data is available. This group is reviewed annually and adjusted to reflect changes in the market including merger and acquisitions.

•  In the case of Mr. Keithley, Ms. Rae and Mr. Plush, performance is measured by the Company’s Return On Invested Capital (ROIC) and for all other participants pre-tax ROA over the three-year performance period. ROIC is defined as net earnings adjusted to exclude net interest income/expense divided by average total shareholders equity less cash and short-term investments. ROIC is used for Mr. Keithley, Ms. Rae and Mr. Plush as they have more ability to impact the Company’s tax planning and capital structure than the other

16

executive officers. The final amount earned pursuant to a performance unit granted in fiscal year 2007 may range from a maximum of twice the initial award, as specified in the agreement, to a minimum of no units depending upon the level of attainment of performance thresholds. The awards granted in fiscal year 2007 to executive officers, if earned, will vest on September 30, 2009. The current expected payout of these awards is at the target level. The following is a matrix that shows the percentage of target that will be paid based on various levels of sales growth compared to the peer companies and levels of ROA or ROIC:

	Sales Growth Compared to Peers

The Committee has established performance metrics of sales growth and ROA/ROIC because the Committee believes these measures are the drivers of the Company’s growth while maintaining high quality earnings.

Equity Award Granting Practices

The Committee’s practice has been to grant long-term incentive awards (options, performance shares and restricted shares) at its November meeting held during the Company’s first fiscal quarter. The Board of Directors adopted a formal policy regarding the granting of equity awards in December 2006, which provides for the following:

•  All options will be made in accordance with the 2002 Stock Incentive Plan.

•  All awards will be granted by the Committee except for stock options, performance shares and restricted shares to be granted by the Chief Executive Officer pursuant to specifically delegated authority, which may not exceed a certain number of shares per fiscal year as established by the Committee. In 2007, the Committee allocated 15,000 shares for this delegated authority. The Chief Executive Officer’s delegated authority does not include any grants to executive officers, which is retained solely by the Committee.

•  All annual grants shall be made at a Committee meeting held in conjunction with the first regularly scheduled Board meeting of the fiscal year, which will generally be scheduled to occur shortly after the announcement of fiscal year-end earnings.

•  Annual grants will have a grant date of the approval date and will have an exercise price of the NYSE closing price on the date of approval or the next trading day after the date of approval if the approval date is not a trading date.

•  Any off-cycle award (awards to new hires or in connection with a promotion or other special recognition) made by either the Committee or the Chief Executive Officer will have a grant date as of February 1, May 1 or August 1 and an exercise price equal to the closing price of the NYSE closing price on the grant date. If the trading window pursuant to the Company’s Insider Trading Policy is closed on such day, the grant date is made effective as of the first day the window is open for trading.

17

In addition, all long-term equity incentive awards are subject to forfeiture, set off and recoupment for any claim that the Company have against an Optionee. These claims include:

(i) direct or indirect disclosure of trade secret or confidential information;

(ii) use of confidential information within the three (3) years preceding Optionee’s termination from employment with the Company;

(iii) any material violation by Optionee of the terms of any written agreement between the Optionee and the Company;

(iv) Any action taken in direct or indirect competition with the Company; or

(v) Any attempt to induce any Company employee or any consultant of the Company to terminate his or her employment or other contractual relationship with the Company.

These rights of forfeiture, set off and recoupment extend to any gain, profit and income Optionee has realized from the exercise of options granted in 2007 or later, net of amounts withheld by the Company in connection with said exercise(s).

Health and Welfare

The Committee has provided named executive officers with the same health and welfare benefits it provides all its other US-based employees; including medical, dental and vision coverage, life and disability insurance, a defined benefit pension plan, a defined contribution plan and an employee stock purchase plan. The named executive officers also have the option to participate in the Company’s Deferred Compensation Plan. In addition, the Company provides each employee with term life insurance with death benefits equal to two times base salary, although executive officers, at their option, may receive whole life insurance rather than term life insurance.

Other Compensation Plans and Perquisites

Retirement Plans

The Company provides opportunities for all employees to save for retirement in three benefit plans: a voluntary defined contribution plan (401(k)), a company funded defined benefit pension plan, an employee stock purchase plan. A deferred compensation plan is also made available to named executive officers and certain other management who meet certain minimum salary requirements as set forth in the Plan. These plans are designed to provide competitive retirement benefits.

401(k)

The Company maintains a defined contribution retirement plan for all its eligible employees in the United States under Section 401(k) of the Internal Revenue Code (the “401(k)”) Plan.

The 401(k) Plan offers the named executive officers and all other employees the opportunity to defer income. In addition, the Company makes a mandatory matching contribution to each employee equal to 25% of up to 6% compensation deferred by the employee, and an additional discretionary match up to 6% of compensation deferred. The rules of the Internal Revenue Code limit the compensation that may be used in applying any deferral election or matching contribution. In 2007, that limit was $225,000 the (“IRS Cap”). In addition, the 401(k) Plan limits contributions to 25% of an employee’s base pay or the IRS Cap, whichever is less. The Company does not provide a tax-deferred non-qualified plan which would allow employees in excess of the IRS Cap to defer and receive a match on that portion of their compensation that does not qualify for the 401(k) Plan.

Defined Benefit Pension Plan

The Company’s United States pension plan provides retirement benefits to eligible participants who terminate employment at or after age 65, or who terminate employment before age 65 with at least five years of service. Benefits commence after termination of employment, but generally not before age 55. Retirement benefits are computed on the basis of pension credits for each year of the employee’s service. Generally, an employee’s pension credits will be equal to the sum of (i) 0.9% of the employee’s high five-year average annual compensation, not in

18

excess of the employee’s Social Security “covered compensation” (as defined by Section 401(I)(5)(E) of the Internal Revenue Code) as of September 30, 1999, plus 1.5% of such average annual compensation in excess of “covered compensation,” with such sum multiplied by the employee’s years of credited service (up to 30 years) through September 30, 1999; plus (ii) 1.2% of the employee’s annual compensation for each plan year beginning on or after October 1, 1999. The employee’s annual retirement benefit, when paid as a life annuity commencing at age 65, will equal the total of the pension credits he or she has earned. The Company does not maintain any Supplemental Retirement plans in which any named executive officer participates.

Employee Stock Purchase Plan

The Company provides an Employee Stock Purchase Plan to all eligible employees, including named executive officers. The plan provides that an employee may defer up to $25,000 per calendar year into the plan. The plan purchases shares with monies deferred once a year giving each plan participant a 5% discount on the share price. The share price is determined by the closing share price on the last day of the plan year which is June 30.

Deferred Compensation Plan

The Deferred Compensation Plan provides Executive Officers and other key employees the opportunity to defer receipt of cash compensation. The Company does not contribute to this plan. Participants may elect to defer all or part of their cash compensation (base salary and annual bonus) for a specified period of years or until retirement. Participants can select from a variety of investment funds from which the earnings on their deferred cash compensation account will be determined. Participants in the Deferred Compensation Plan are considered unsecured creditors of the Company.

Perquisites

The Company provides executive officers with a Company car, a cell phone, whole life insurance equal to two times their annual salary, access to financial planning services, and access to a health club membership. In addition, to assist the Company in conducting business meetings and/or entertainment, the Company pays the cost of certain club dues for some officers. Although these officers may derive some personal benefit for their use, club memberships are used extensively for business purposes and all personal expenses are born entirely by the executive.

Change in Control and Other Severance Arrangements

Upon a change in control as defined in the Keithley Instruments, Inc. 2002 Stock Incentive Plan, all stock options and any outstanding stock appreciation rights granted under the Plan shall become immediately exercisable in full and all restricted stock grants, including performance units, become immediately vested and any applicable restrictions lapse. Performance units vest at target levels. The Company does not have a formal severance policy, and the Committee must review and approve the severance of any officer. With the exception of Mr. Plush, no executive officer has a separate agreement providing change in control benefits, other than with respect to their equity awards.

Company Stock Ownership Guidelines

While the Company encourages its executive officers to own Common Shares, it does not have a formal policy requiring specified levels of share ownership. The Committee believes that its current compensation structure has properly aligned the named executive officers with shareholder interest and, therefore, a formal policy is not necessary.

(1)

This amount includes $55,304 deferred under the Supplemental Deferred Compensation Plan. This amount is also reported in the “Executive Contributions in Last Fiscal Year” column of the Nonqualified Deferred Compensation Table for the Fiscal Year 2007 table on page 24.

(2)

Represents the dollar amount of equity compensation cost recognized for financial reporting purposes with respect to fiscal year 2007, computed in accordance with SFAS 123(R). See Note H of Notes to Consolidated Financial Statements included in “Part II — Item 8 — Financial Statements and Supplemental Data” of the Company’s Annual Report on Form 10-K for fiscal year 2007 for a description of the assumptions used in that computation. The actual value realized to the Named Executive Officers with respect to stock awards will depend on the market value of Keithley Stock on the date that final PAU grants are determined and when such stock granted thereunder is sold, and with respect to option awards, will depend on the difference between the market value of Keithley Common Stock on the date the option is exercised and the exercise price.

(3)	Represents amounts earned under the Annual Incentive Plan. The Company did not achieve the threshold targets specified in the Plan, therefore, no amounts were earned in fiscal year 2007.
(4)	Amounts consist of the change in the annual actuarial present value of the pension benefits for each Named Executive Officer, as also reported in the Pension Benefits at September 30, 2007 table on page 23. For 2006, the discount rate used to determine the present value of the pension benefit was 6.625% as opposed to 6.375% in 2007. None of the Named Executive Officers received above-market or preferential earnings on deferred compensation.

(1)	The targets for the Annual Incentive Plan were granted on August 10, 2006, but because the Company did not achieve the thresholds for either target for the Annual Incentive Plan, no annual incentive payouts were made for fiscal year 2007.
(2)	Represents stock options with an exercise price equal to the fair market value of Keithley Common Shares on the date of grant. The options vest and become exercisable fifty percent (50%) on the second anniversary of the date of grant and then twenty five percent (25%) on each anniversary thereafter. All unvested options terminate upon the termination of employment for any reason. There are additional forfeiture and recoupment mechanisms for conduct that is detrimental to the Company. See forfeiture discussion on page 18. In any event, options expire 10 years from the date of grant unless otherwise expired as described above.
(3)	These amounts are determined by using FAS 123(R) valuations times the number of options granted and the target number of PAU’s granted. For options, the FAS 123(R) per share valuation was $5.443 and for PAU’s it was $14.00 per share.

(1)	The Company generally does not enter into employment agreements with its executive officers. Upon termination from employment, the Keithley Instruments, Inc. Employees’ Pension Plan may provide certain benefits to participants, including executive officers, depending on the reason for termination. In addition, the Annual Incentive Plan and Performance Award Agreements provide the Committee discretion to award terminated employees a pro-rata share of an award depending on the circumstances of their termination.
(2)	All Equity Awards have accelerated vesting of the awards upon a change of control. The sums shown represent the sum of (a) the in-the-money value of the unvested stock options and (b) the value of PAU’s awarded at target levels. All values were computed as of the end of fiscal year 2007 and based on the closing price of Keithley Common Stock on the last trading day of fiscal year 2007 ($10.60).
(3)	While the Company generally does not enter into employment agreements with its executive officers it did, however, during a transition in management in 1994 enter into an employment agreement with Mr. Plush. The amount shown represents amounts that the Company would owe Mr. Plush if he were terminated without cause as defined in the Employment Agreement by and between the Company and Mr. Plush dated April 7, 1994 ($303,696 represents a true up of benefits due under the Pension Plan which would be paid over time and $383,384 represents severance that would be paid in the same manner as payroll and $10,000 represents the amount for outplacement services.) The Agreement provides for the following:

•  In the case of change of control provides for the Employment Agreement to extend for the rest of its term but in no event less than eighteen (18) months.

24

In addition, the Employment Agreement provides for the following severance in case of termination without cause:

•  At least six (6) months of severance or one (1) month of service for each year of service not to exceed eighteen (18) months, whichever is greater (paid as salary continuation);

•  Full participation in the Annual Incentive Plan provided the termination is after June 30th

•  Full participation in any performance award if the performance measuring period is within six (6) months following his termination

•  Thirty (30) days to exercise all vested options; provided such thirty (30) days does not extend the term of said options

•  Supplemental Retirement Benefit to true up his pension benefit

•  All fringe benefits that he was receiving immediately prior to his termination for the period of his severance

•  Outplacement services not to exceed $10,000

Audit Committee Report

The Audit Committee has reviewed and discussed with Keithley’s management and PricewaterhouseCoopers LLP the audited consolidated financial statements of Keithley contained in the Annual Report on Form 10-K for the 2007 fiscal year. The Audit Committee has also discussed with PricewaterhouseCoopers LLP the matters required to be discussed pursuant to SAS No. 61, as amended by Statement on Auditing Standards No. 90, (Codification of Statements on Auditing Standards, AU Section 380), which includes, among other items, matters related to the conduct of the audit of Keithley’s financial statements.

The Audit Committee has received and reviewed the written disclosures and the letter from PricewaterhouseCoopers LLP required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), and has discussed with PricewaterhouseCoopers LLP its independence from Keithley.

In addition, the Audit Committee, in consultation with management, the independent registered public accounting firm and the internal auditors, has reviewed management’s report on internal control over financial reporting as of September 30, 2007 and the independent registered public accounting firm’s attestation report (which are required pursuant to Section 404 of the Sarbanes-Oxley Act of 2002), and has considered the effectiveness of the Company’s internal control over financial reporting.

Based on these reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in Keithley’s Annual Report on Form 10-K for its 2007 fiscal year for filing with the Securities and Exchange Commission.

PROPOSAL TWO:
APPROVAL OF AMENDMENTS TO THE CODE OF REGULATIONS

The Board of Directors unanimously approved and recommends that the Corporation’s shareholders approve the amendments to the Corporation’s Code of Regulations described below. The proposed amendments are separated into four subproposals to allow shareholders to focus and vote on each significant change. Each subproposal will be voted on separately, and the adoption or rejection of one subproposal will not affect the adoption or rejection of another subproposal. The proposed amendments are incorporated in the Code of Regulations, a copy

26

of which is attached as Appendix A and marked to show the proposed amendments. These amendments include the following:

(a)   Modernization and Clarification Amendments

The last time the Corporation amended its Code of Regulations was February 9, 1985. Since that time, there have been numerous changes in Ohio law, federal securities law and New York Stock Exchange (“NYSE”) regulations that have increased flexibility for corporations in communicating with and conducting meetings of directors and shareholders, among other corporate governance matters. Many of the changes that have been made to these laws and regulations and that are proposed for future adoption relate to significant advances made in the area of electronic communications that permit notices, voting, proxy authorization and meeting attendance to occur electronically.

Under the existing Code of Regulations, the Corporation is unable to take advantage of many of these changes and will be unable to take advantage of subsequent changes relating to corporate governance practices currently being proposed for promulgation by the SEC and NYSE. Furthermore, there are several sections of the Code of Regulations that need to be amended to correct typographical errors or revised to reflect the current practices of the Corporation that have evolved since 1985. None of the proposed changes in this subproposal (a) diminish or negatively impact the existing substantive rights of shareholders.

Accordingly, the amended Code of Regulations would provide for the following changes to modernize and clarify the existing Code of Regulations:

•  The existing Code of Regulations requires the Corporation to issue a written notice to shareholders of record, by personal delivery or mail, setting forth the time, place and purposes of each shareholder meeting and does not allow for notice to be given by more modern means of communication, such as e-mail or fax.  The proposed amendments to the Code of Regulations would allow notice of shareholder meetings to be given by personal delivery, mail, overnight delivery service or other means of communication authorized by the shareholder to whom notice is given (which means could include e-mail or fax). This change is intended to reflect changes in technology and Section 1701.41(A) of the Ohio Revised Code, which allows for notice of shareholder meetings to be delivered in this manner. See Article II, Section (d)(1) of the amended Code of Regulations.

•  The existing Code of Regulations requires the Corporation to issue notice of the time and place of any meeting of the Board of Directors by personal delivery, telephone, mail, telegram or cablegram and does not allow for notice to be given by more modern means of communication, such as e-mail or fax.  The proposed amendments to the Code of Regulations would allow notice of director meetings to be given by personal delivery or by mail, telegram, cablegram, overnight delivery service, telephone, electronic mail or any other means of communication authorized by the director. This change is intended to reflect changes in technology and Section 1701.61(C) of the Ohio Revised Code, which allows for notice of director meetings to be delivered in this manner. See Article III, Section 4(d) of the amended Code of Regulations.

•  The existing Code of Regulations requires a proxy to be appointed in writing.  The proposed amendments to the Code of Regulations would permit shareholders to appoint a proxy using a modern form of verifiable information, such as e-mail, over the internet or by telephone. Shareholders will still have the right, if they so choose, to appoint a proxy in writing. This change is intended to reflect changes in technology and Section 1701.48(A) of the Ohio Revised Code, which allows for a proxy to be appointed by a writing or appointed by a verifiable communication authorized by the shareholder. See Article II, Section (j) of the amended Code of Regulations.

•  The existing Code of Regulations has a section prescribing the order of business at a meeting of the shareholders that must be followed unless waived or otherwise determined by a shareholder vote.  The proposed amendments to the Code of Regulations provide for the adoption by the Board of Directors of rules and regulations regarding the conduct of meetings and that the chairperson of a shareholder meeting will determine the order of business at such meeting. This change is intended to provide the Corporation with greater flexibility in setting meeting procedures and accommodating circumstances such as the use of

27

electronic communications by giving the Board and chairperson discretion with respect to such matters. See Article II, Section (h) of the amended Code of Regulations.

•  The existing Code of Regulations provides that a director resignation will take effect upon receipt by any incumbent corporate officer other than an officer who is also the resigning director.  The proposed amendments to the Code of Regulations provide that a director resignation will take effect upon being received by the President or the Secretary of the Corporation, unless some other time is specified in the resignation notice. This change reflects the current practices of the Corporation and is intended to ensure that any disclosure obligations or corporate governance matters triggered by such resignation are addressed in a timely and appropriate manner. For example, director resignations may trigger disclosures under federal securities laws and new Board or committee appointments may be needed to maintain compliance with SEC and NYSE requirements. The proposed amendment would allow resignation notices to be received by an appropriate officer of the Corporation to address such matters and to ensure compliance with timing requirements triggered by the effectiveness of such resignation. See Article III, Section 3(b) of the amended Code of Regulations.

•  The existing Code of Regulations requires regular meetings of the Board of Directors to be held immediately following the adjournment of the annual meeting of shareholders or a special meeting of shareholders at which directors are elected.  The proposed amendments to the Code of Regulations provide that regular meetings of the Board will be held at such times and places as may be fixed by the Board. This change reflects the current practices of the Corporation and is intended to allow the Board greater flexibility in scheduling meetings. See Article III, Section 4(a) of the amended Code of Regulations.

•  The existing Code of Regulations provides that the Board of Directors may appoint certain of its members to act as a committee or committees, but requires any such committees to have at least three members.  The proposed amendments to the Code of Regulations provide that a committee of the Board may consist of one or more directors. This change is intended to provide the Board with additional flexibility to authorize action by a subset of its members and reflect changes in Section 1701.63(A) of the Ohio Revised Code, which now only requires committees to consist of one or more directors. See Article III, Section 6(a) of the amended Code of Regulations.

•  The existing Code of Regulations includes certain procedural requirements in order for a director to invite a person who is not a director to attend a Board meeting. The procedural requirements include providing written notice at least twenty-four hours in advance stating the reason and obtaining a vote of approval by a majority of the directors in attendance as the first order of business.  This provision would be deleted as part of the proposed amendments to the Code of Regulations. The removal of this requirement is intended to reflect the current practices of the Corporation and increase the flexibility of the Board in regard to inviting people who are not directors to Board meetings. See the deletion appearing in Article III, Section 9 of the amended Code of Regulations.

•  The existing Code of Regulations requires that the person or persons serving as the President and the Chairman of the Board be directors.  The proposed amendments to the Code of Regulations would eliminate the requirement that the Corporation’s President be a member of the Board to provide flexibility with respect to succession planning for both Board membership and the office of President and ensuring compliance with NYSE and SEC director independence requirements. See Article IV, Section 1 of the amended Code of Regulations.

•  The existing Code of Regulations has two separate sections regarding the compensation of directors and officers. One section provides that the Board of Directors may allow compensation and reimbursement of expenses to directors for attendance at meetings, for serving on a committee or for any special services. The other provision provides that the Chairman of the Board or the President of the Corporation, unless otherwise determined by a majority of the Board, shall determine the compensation to be paid to all officers and other employees.  The proposed amendments to the Code of Regulations consolidate the two compensation sections into one, which provides that the directors, by a majority vote, will have the authority to establish reasonable compensation for services to the Corporation by directors and officers, or to delegate such authority to (a) one or more officers or directors or (b) a committee of the Board. This change is intended to reflect the current practices of the Corporation and SEC and NYSE rules regarding

28

compensation matters, by providing that compensation will be fixed by the Board or delegated to the compensation or other committee of the Board or the Corporation’s officers as appropriate. See Article IV, Section 4 and the deletion in Article III, Section 8 of the amended Code of Regulations.

•  The existing Code of Regulations contains several typographical errors and parenthetical references to sections of the Ohio Revised Code.  The proposed amendments to the Code of Regulations remove the parenthetical references in various sections and correct the typographical errors. The removal of the references will prevent the Code of Regulations from becoming inaccurate due to subsequent changes in the Ohio Revised Code.

(b)   Notice of Shareholder Business and Director Nominations

•  The existing Code of Regulations does not expressly provide any time limitations or procedural requirements regarding a shareholder’s ability to bring business before an annual meeting of shareholders.  The proposed amendments to the Code of Regulations would incorporate the existing requirements regarding the submission of shareholder proposals set forth in Rule 14a-8 under the Securities Exchange Act of 1934 (the “Exchange Act”) by expressly setting forth the time period in which a shareholder must provide notice to the Corporation and the procedure to be followed in order to submit a proposal for consideration at a meeting. Adoption of this amendment would not materially impair a shareholder’s ability to bring business before a meeting because the amendment is no more restrictive than the current requirements under Rule 14a-8. Under the amended Code of Regulations, a shareholder would be required to submit notice of a proposal to the Corporation’s principal executive offices no later than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual meeting (unless the date of the meeting is changed by more than 30 days from the anniversary date). The proposed amendments to the Code also specify the information that is required to be set forth in any such notice. See Article II, Section (l) of the amended Code of Regulations.

•  The existing Code of Regulations does not expressly provide any time limitations or procedural requirements regarding a shareholder’s ability to nominate directors for election to the Board at any meeting of shareholders called for the election of directors.  The proposed amendments to the Code of Regulations would specifically incorporate the existing requirements regarding the submission of shareholder proposals set forth in Rule 14a-8 under the Exchange Act by expressly setting forth the time period in which a shareholder must provide notice to the Corporation and the procedure to be followed in order to nominate a director for election at a meeting. Under the amended Code of Regulations, a shareholder would be required to submit notice of a nomination to the Corporation’s principal place of business no later than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual meeting (unless the date of the meeting is changed by more than 30 days from the anniversary date), or in the case of a special meeting at which directors are to be elected, within certain time periods following the notice or public disclosure of the special meeting. Adoption of this amendment would not materially impair a shareholder’s ability to nominate a director before a meeting because the amendment is no more restrictive than the current requirements under Rule 14a-8. The proposed amendments to the Code of Regulations also specify the information that is required to be set forth in any such notice. See Article III, Section (d) of the amended Code of Regulations.

(c)   Authority of the Board to Fix the Number of Directors and Amend the Code of Regulations

•  The existing Code of Regulations provides that only shareholders may fix or change the number of directors and that if less than the current number of directors are elected at a shareholder meeting, the number will then be reduced to the number of directors elected unless the number is otherwise fixed at such meeting.  The proposed amendments to the Code of Regulations will also allow the Board of Directors to fix or change the number of directors and will eliminate the provision setting the number at the number of directors actually elected where another number is not specifically fixed at the meeting providing for such election. These changes are consistent with Section 1701.56(A)(2) of the Ohio Revised Code, which provides that a Corporation’s articles or regulations may authorize directors to change the number of directors, and are intended to provide greater flexibility to the Board in managing its size and membership in accordance with SEC and NYSE independence and committee requirements and corporate governance considerations.

29

Adoption of the amendment would not materially impair the shareholders’ ability to fix or change the number of directors, since the shareholders will have this right in addition to the Board under the amended Code of Regulations. See Article II, Section 2(b).

•  The existing Code of Regulations provides that only shareholders may amend the Code of Regulations.  The proposed amendments to the Code of Regulations allow the Board of Directors to amend the Code unless a provision of the Ohio Revised Code reserves such authority to the shareholders. Accordingly, the Board would be able to make ministerial and other changes to the Code of Regulations without the time and expense of seeking shareholder approval. This change is intended to reflect changes in Section 1701.11 of the Ohio Revised Code that now permit directors to make certain amendments to a corporation’s code of regulations without shareholder approval so long as such amendments do not divest or limit the shareholders’ power to adopt, amend or repeal the regulations of the corporation. The amendment to the Ohio Revised Code aligns Ohio with many other jurisdictions, such as Delaware, that also permit similar flexibility. Under the Ohio Revised Code and the proposed amendments to the Code of Regulations (as described in the following paragraph), the Board will be required to promptly provide notice of such amendments to the shareholders. The amended Code would not affect the shareholders’ ability to amend the Code of Regulations. See Article XII of the amended Code of Regulations.

•  The existing Code of Regulations provides that if an amendment to the Code of Regulations is adopted by written consent without a meeting of the shareholders, the Secretary must mail a copy of the amendment to each shareholder who is entitled to vote on, but did not participate in the adoption of, such amendment.  The proposed amendments to the Code of Regulations permit notice of any amendment to also be sent by more modern means of communication, such as e-mail, if authorized by the shareholder to whom a copy is sent or by including a copy of the amendment in a report filed with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act within 20 days after the adoption of the amendment. The amendment to the Code of Regulations is intended to reflect changes in Section 1701.11 of the Ohio Revised Code, which now permit the use of electronic means or SEC filings to provide notice of an amendment to the shareholders. See Article XII of the amended Code of Regulations.

(d)   NYSE Direct Registration Requirements

•  The existing Code of Regulations does not prohibit, but also does not contain express terms providing for the use of uncertificated shares.  The proposed amendments to the Code of Regulations would expressly permit the Corporation to issue uncertificated shares and contain provisions relating to the registration and transfer of such shares. These amendments are intended to reflect new NYSE rules requiring listed companies to cause their shares to be eligible for inclusion in a direct registration system (“DRS”) by January 1, 2008. To be eligible for inclusion in a DRS, the Corporation must provide that its shares may be evidenced by records in the DRS without physical (paper) certificates evidencing those shares. The existing Code of Regulations allows the Corporation to comply with this requirement, since uncertificated shares are permitted under the Ohio Revised Code; however, the amended Code of Regulations would contain express provisions regarding the issuance of uncertificated shares in accordance with the requirements set forth in the Ohio Revised Code in addition to the provisions governing certificated shares. Except as may otherwise be required by law [and subject to the terms of any applicable employee benefit plan], the rights and obligation of holders of uncertificated shares and holders of physical shares for a particular class and series of shares would be identical.

Under the NYSE requirements, the Corporation is not required to issue uncertificated shares. It is only required to be eligible to do so. Whether or not the Corporation elects to issue uncertificated shares, the proposed amendments would not affect shareholders who choose to hold their shares in the Corporation through a brokerage or other account in “street” name. If the Corporation begins to participate in DRS, under the current NYSE rules, such shareholders will have the option of continuing to hold their shares in the Corporation through a brokerage or other account in “street” name or holding the shares in their own name through the DRS. See Article VII of the amended Code of Regulations.

30

A majority of votes represented by the outstanding Common Shares and the Class B Common Shares voting together is required to approve the amendments to the Code of Regulations. Abstentions and broker non-votes will have the same effect as votes against the proposals.

The Board of Directors recommends a vote for the approval of the amendments to the Code of Regulations.

OTHER MATTERS

The Board of Directors of the Company is not aware of any matter to come before the meeting other than the election of Directors. However, if other matters shall properly come before the meeting, it is the intention of the persons named in the proxies to vote in accordance with their best judgment on such matters.

Any shareholder proposal intended to be presented at the Annual Meeting of Shareholders to be held in 2009 in compliance with Rule 14a-8 promulgated under the Exchange Act must be received by the Company at its principal executive offices not later than September 6, 2008, for inclusion in the Board of Directors’ proxy statement and form of proxy relating to that meeting. The Company will not be required to include in its proxy statement and form of proxy a shareholder proposal that is received after that date or which otherwise fails to meet the requirements for shareholder proposals established by regulations of the Securities and Exchange Commission. In addition, if a shareholder intends to present a proposal at the Company’s 2009 Annual Meeting without the inclusion of the proposal in the Company’s proxy materials, the appointed proxies may exercise their discretionary voting authority for any proposal received after November 20, 2008, without any discussion of the proposal in the Company’s proxy statement.

Shareholders and other interested parties may send written communications to the Board by mailing them to the Board of Directors, c/o Joseph P. Keithley, Chairman, Keithley Instruments, Inc., 28775 Aurora Road, Cleveland, Ohio 44139. All communications will be forwarded to the Directors.

Upon the receipt of a written request from any shareholder entitled to vote at the forthcoming Annual Meeting, the Company will mail, at no charge to the shareholder, a copy of the Company’s Annual Report on Form 10-K, including the financial statements and schedules required to be filed with the Securities and Exchange Commission pursuant to Rule 13a-1 under the Securities Exchange Act of 1934, as amended, for the Company’s most recent fiscal year. Requests from beneficial owners of the Company’s voting securities must set forth a good faith representation that as of the record date for the Annual Meeting, the person making the request was the beneficial owner of securities entitled to vote at such Annual Meeting. Written requests for such report should be directed to:

Mark J. Plush

Vice President and Chief Financial Officer

Keithley Instruments, Inc.

28775 Aurora Road

Cleveland, Ohio 44139

You are urged to sign and return your proxy promptly in order to make certain your shares will be voted at the Annual Meeting. For your convenience, a return envelope is enclosed requiring no additional postage if mailed in the United States.

For business to be properly brought before an annual meeting by a Shareholder (other than the nomination of a person for election as a Director, which is governed by paragraph (d) of Article III, Section 2 of this Code of Regulations), the Shareholder must have given timely notice thereof in writing to the Secretary of the Corporation.

To be timely, a Shareholder’s notice must be delivered to or mailed and received at the principal executive offices of the Corporation no later than ninety (90) days nor more than one hundred twenty (120) days prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is changed by more than thirty (30) days from such anniversary date, notice by the Shareholder to be timely must be delivered to or mailed and received at the principal executive offices of the Corporation no later than ninety (90) days nor more than one hundred twenty (120) days prior to such annual meeting and no later than the close of business on the tenth (10th) day following the earlier of (i) the date on which notice of the date of the

A-3

meeting was mailed and (ii) the date on which public disclosure of the meeting date was made.
