Q:             If my broker holds my shares in “street name,” will my broker vote my shares for me?

A:              If your shares are held in a brokerage account, you will receive a full meeting package including a voting instruction form to vote your shares. Your brokerage firm may permit you to vote by the Internet or by telephone. Brokerage firms have the authority under New York Stock Exchange rules to vote their client’s unvoted shares on certain routine matters. If you do not vote, your brokerage firm may choose to vote for you on the election of five directors and ratification of the selection of Deloitte & Touche LLP as the independent registered public accounting firm for Integrys Energy Group and its subsidiaries for 2007 or they may leave your shares unvoted on these proposals. Approval of the executive compensation plans is not considered routine and can only be voted by your broker with your specific instructions. Therefore, we urge you to respond to your brokerage firm so that your vote will be cast.

Q.             If my shares are held in “street name” (by a bank or broker), can I vote my shares at the annual meeting?

A:              If your shares are held in street name you may vote your shares at the annual meeting ONLY if you bring a Legal Proxy to the annual meeting. The Legal Proxy would be provided by your bank or broker. You must request this Legal Proxy from your bank or broker; they will not automatically supply one to you.

Q:             What if I receive more than one proxy card?

A:              If you receive more than one proxy card this means your shares are in more than one account. Please vote all the shares that you own.

American Stock Transfer & Trust, Wells Fargo Bank and The Northern Trust Company will keep how you vote your shares confidential.

Shares held in the Peoples Energy Capital Accumulation Plan or the Peoples Energy Thrift Plan will be voted at the discretion of the trustee, The Northern Trust Company, and not by plan participants.

ELECTION OF DIRECTORS

Our board of directors is currently made up of 16 directors. The directors are divided into three classes. Each year one class of directors is elected to a three-year term. At the time of the closing of the merger of Peoples Energy Corporation into a subsidiary of Integrys Energy Group, the size of the Board of Directors was increased from 9 members to 16 members with the addition of 7 former directors of Peoples Energy. At that time the board appointed the 16 directors into 3 classes. As provided by the By-laws of Integrys Energy Group, the first class of 5 directors is standing for election at this year’s annual meeting. The tables below reflect information as of March 22, 2007.

Individuals nominated for election are:

Class A — Term Expiring in 2007

6

The board of directors has no reason to believe that any of these nominees will be unable or unwilling to serve as a director if elected. If any nominee is unable or unwilling to serve, the shares represented by proxies solicited by the board will be voted for the election of another person the board may recommend.

The board of directors recommends a vote “FOR” the election to the board of each of the foregoing nominees. Proxies solicited by the board of directors will be voted “FOR” the above nominees unless the shareholder has specified otherwise.

Current directors not standing for election this year are:

Class B — Term Expiring in 2008

7

Class C — Term Expiring in 2009

8

*     For former directors of Peoples Energy Corporation the years of service reflected in the tables include their years of service as directors of Peoples Energy Corporation. Each of them began to serve as a director of Integrys Energy Group in February 2007.

On February 8, 2007, the board of directors reviewed the business and other relationships of all directors of Integrys Energy Group. The board affirmatively determined that all non-management directors are independent as defined in the New York Stock Exchange listing standards, meet the independence standards adopted by the board of directors (set forth below) and have no other material relationships with Integrys Energy Group. In addition, Diana S. Ferguson, Michael E. Lavin, James L. Kemerling, Albert J. Budney, Jr., Ellen Carnahan and William F. Protz, Jr. meet additional independence standards for audit committee members. All directors are independent directors with the exception of Larry L. Weyers, President and Chief Executive Officer of Intergrys Energy Group, Inc.

Categorical Independence Standards for Directors

A director who at all times during the previous three years has met all of the following categorical standards and has no other material relationships with Integrys Energy Group shall be deemed to be independent:

1.               Integrys Energy Group has not employed the director, and has not employed (except in a non-executive officer capacity) any of his or her immediate family members. Employment as an interim Chairman or Chief Executive Officer shall not disqualify a director from being considered independent following that employment.

2.               Neither the director, nor any of his or her immediate family members, has received more than $100,000 per year in direct compensation from Integrys Energy Group, other than director and committee fees, and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service). Compensation received by a director for former service as an interim Chairman or Chief Executive Officer need not be considered in determining independence under this test. Compensation received by an immediate family member for service as a non-executive employee of Integrys Energy Group need not be considered in determining independence under this test.

3.               The director has not been employed by, or affiliated with Integrys Energy Group’s present or former internal or external auditor, nor have any of his or her immediate family members been so employed or affiliated (except in a non-professional capacity).

9

4.               Neither the director, nor any of his or her immediate family members, has been part of an “interlocking directorate” in which any of Integrys Energy Group’s present executives serve on the compensation (or equivalent) committee of another company that employs the director or any of his or her immediate family members in an executive officer capacity.

5.               Neither the director, nor any of his or her immediate family members (except in a non-executive officer capacity), has been employed by a company that makes payments to, or receives payments from, Integrys Energy Group for property or services in an amount which, in any single fiscal year, exceeds the greater of $1 million or 2 percent of such other company’s consolidated gross revenues.

6.               Neither the director, nor any of his or her immediate family members, has been an employee, officer or director of a foundation, university or other non-profit organization to which Integrys Energy Group gives directly, or indirectly through the provision of services, more than $1 million per annum or 2 percent of the total annual donations received (whichever is greater).

In addition to satisfying the criteria set forth above, directors who are members of Integrys Energy Group’s Audit Committee will not be considered independent for purposes of membership on the Audit Committee unless they satisfy the following additional criteria:

1.               A director who is a member of the Audit Committee may not, other than in his or her capacity as a member of the Audit Committee, the Board, or any other Board committee, accept directly or indirectly any consulting, advisory, or other compensatory fee from Integrys Energy Group or any subsidiary thereof, provided that, unless the rules of the New York Stock Exchange provide otherwise, compensatory fees do not include the receipt of fixed amounts of compensation under a retirement plan (including deferred compensation) for prior service with Integrys Energy Group (provided that such compensation is not contingent in any way on continued service).

2.               A director, who is a member of the Audit Committee may not, other than in his or her capacity as a member of the Audit Committee, the Board, or any other Board committee, be an affiliated person of Integrys Energy Group.

3.               If an Audit Committee member simultaneously serves on the audit committees of more than two other public companies, then the Board must determine that such simultaneous service would not impair the ability of such member to effectively serve on Integrys Energy Group’s Audit Committee. Integrys Energy Group shall disclose this determination in its proxy statement.

APPROVAL OF PROPOSED
INTEGRYS ENERGY GROUP 2007
OMNIBUS INCENTIVE COMPENSATION PLAN

The board of directors of Integrys Energy Group will adopt the Integrys Energy Group 2007 Omnibus Incentive Compensation Plan (the “2007 Incentive Compensation Plan”), subject to approval by the holders of common stock at the Integrys Energy Group 2007 Annual Meeting of Shareholders.

The board seeks shareholder approval of the Integrys Energy Group 2007 Omnibus Incentive Compensation Plan, which authorizes 3.5 million shares of Common Stock for use in future grants made under the plan. If the 2007 Incentive Compensation Plan is approved, no further grants will be made under the Integrys Energy Group 2005 Omnibus Incentive Compensation Plan (the “2005 Incentive Compensation Plan”), although the 2005 Incentive Compensation Plan will continue to operate in accordance with its terms with respect to grants previously made.

The board also seeks approval of the plan to satisfy requirements of tax law necessary to preserve Integrys Energy Group’s ability to claim tax deductions for compensation to executive officers that may exceed $1 million as a result of awards provided by this plan that otherwise satisfy the requirements of Internal Revenue Code Section 162(m). Internal Revenue Code Section 162(m) limits the tax deduction for compensation in excess of $1 million in a given year paid to the Chief Executive Officer, Chief Financial Officer and the three additional most highly compensated executive officers. “Performance based” compensation meeting certain requirements is not counted against the $1 million limit and remains fully deductible for tax purposes. Shareholder approval of the general business criteria of this plan and the maximum amounts that may be awarded under the plan, even without shareholder approval of specific targeted levels of performance, will qualify otherwise compliant incentive awards under this plan as performance based compensation and is expected to allow full tax deductibility of the performance-based awards for the next five years.

Plan Description

The 2007 Incentive Compensation Plan provides both short-term (annual) and long-term incentive awards for eligible employees. Annual incentive awards are paid in cash and take the form of annual performance rights. Long-term incentive awards are stock-based, and may take the form of performance stock rights (“Performance Shares”), stock options (“Options”), stock appreciation rights (“SARs”), or other stock-based awards, such as restricted stock (“Other Stock Awards”). Performance Shares, Options, SARs, and Other Stock Awards are sometimes collectively referred to as “Plan Awards.” Final Awards are defined as awards ultimately issued pursuant to an annual performance right or a performance stock right. As noted above, the board seeks shareholder approval of the 2007 Incentive Compensation Plan, which authorizes the issuance of 3.5 million shares of Common Stock for use in future grants. Of the 3.5 million total shares of Common Stock, no more than 1.5 million will be used for grants of Performance Shares and Other Stock Awards.

Material Terms of the 2007 Omnibus Incentive Compensation Plan

The following summary description of the 2007 Incentive Compensation Plan is subject in all respects to the full text of the 2007 Incentive Compensation Plan. A copy of the 2007 Incentive Compensation Plan will be furnished without charge to any person entitled to receive a copy of the Integrys Energy Group Form 10-K upon written request to Integrys Energy Group Inc., Attention: Peter H. Kauffman, Secretary and Chief Governance Officer, 130 East Randolph Drive, Chicago, Illinois 60601.

11

Purpose:

The 2007 Incentive Compensation Plan is designed to:

·       Attract and retain executives and other key employees of outstanding training, experience and ability;

·       Motivate key employees by means of performance-related incentives to achieve performance goals; and

·       Enable key employees to participate in the growth and financial success of Integrys Energy Group.

Stock Subject to the Plan:

The total number of shares of Integrys Energy Group Common Stock available for awards under the 2007 Incentive Compensation Plan will be 3.5 million shares subject to adjustment for stock splits, stock dividends and certain other transactions or events affecting Integrys Energy Group Common Stock. During any calendar year in which any part of the 2007 Incentive Compensation Plan is in effect, a maximum of 1.0 million shares of Integrys Energy Group’s Common Stock may be subject to Options or SARs that may be granted to an individual, who on the last day of a taxable year, is the chief executive officer, chief financial officer or any of the three additional highest compensated officers of Integrys Energy Group and its subsidiaries (each a “Covered Executive”) and a maximum of 250,000 shares of Integrys Energy Group Common Stock may be granted as Final Awards in any calendar year pursuant to Performance Stock Rights (as described below) or other performance-based awards to any Covered Executive. In each case the maximum number is subject to adjustment for stock splits, stock dividends and certain other transactions and events.

Administrator:

The Compensation Committee of the Integrys Energy Group board of directors or any other committee which the board may appoint, which in either case consists of not less than two members of the board each of whom meets the “outside” director requirements of Section 162(m) of the Internal Revenue Code (the “Code”), the New York Stock Exchange independence requirements, and the “non-employee director” requirements of Rule 16b-3(b)(3) under the Securities Exchange Act of 1934 (the “Exchange Act”) (either referred to as the “Committee”) will administer the 2007 Incentive Compensation Plan. The 2007 Incentive Compensation Plan authorizes the Committee to establish rules and regulations as it may deem appropriate for the proper administration of the 2007 Incentive Compensation Plan, and to make determinations under and interpretations of the 2007 Incentive Compensation Plan and to take other steps in connection with the 2007 Incentive Compensation Plan and Plan Awards as it may deem necessary or advisable, in each case in its sole discretion. The board may also exercise any authority granted to the Committee except to the extent that the grant or exercise of authority by the board would cause any award that is intended to be a qualified performance-based award to cease to qualify for exemption under Section 162(m) of the Code. The Committee may delegate any or all of its powers and duties under the 2007 Incentive Compensation Plan, including its authority to make awards under the 2007 Incentive Compensation Plan or to grant waivers of 2007 Incentive Compensation Plan conditions, to one or more other persons or committees as it shall appoint provided the Committee may not delegate its authority to:

·       Act on matters affecting any participant who is subject to the reporting requirements of Section 16(m) of the Exchange Act, or the liability provisions of Section 16(b) of the Exchange Act; or

·       Amend or modify the 2007 Incentive Compensation Plan.

12

Annual Performance Rights and Final Awards:

The Committee may from time to time grant or authorize the granting of Annual Performance Rights under the 2007 Incentive Compensation Plan to such officers or other employees of Integrys Energy Group or any of its subsidiaries, or of any joint venture in which Integrys Energy Group or any of its subsidiaries has a substantial equity interest (each, an “Employee”) as the Committee may select. An Annual Performance Right is the right to receive up to the amount described in a participant’s award agreement, taking into account the Target Award and the Performance Formula, upon the attainment of one or more specified Performance Goals, subject to the terms and conditions of the award agreement and the 2007 Incentive Compensation Plan. The Target Award is the amount of compensation or the number of shares of Integrys Energy Group Common Stock to be earned by a participant if all the Performance Goals are achieved at the specified level. With respect to an Annual Performance Right that is intended to constitute performance based compensation for purposes of Internal Revenue Code Section 162(m), the Performance Goals for a participant who is a Covered Executive will be a performance measure that is based upon one or more of the following business criteria which the Committee establishes with respect to Integrys Energy Group and/or any of its subsidiaries or a division, business unit or component of Integrys Energy Group or a subsidiary: asset change, asset turnover, capital employed in the business, capital spending, cash flow, cost structure improvements, complexity reductions, customer loyalty, customer value, diversity, earnings growth, earnings per share, economic value-added, environmental health, safety, occupational health reportable incidents, workers compensation costs, increase in customer base, market efficiency, energy price weighted availability of generation facilities, market share, net cash balance, net income, net income margin, net operating cash flow, operating profit margin, operations and maintenance reduction, electric and/or gas utility rate levels, productivity, response time, profits before tax, quality/customer satisfaction, return on assets, return on capital, return on equity, return on net operating assets, return on sales, revenue growth, sales margin, sales volume, system reliability, total shareholder return, variable margin and working capital. In any other case, the Performance Goals may be based on one or more of the business criteria described above or any other criteria based on individual, business unit, subsidiaries, group or Company performance selected by the Committee. A Performance Formula is applied to the Performance Goals in determining the percentage of the Target Award earned by the participant with respect to a Plan Award.

A Final Award of $5 million is the maximum amount that may be granted to a Covered Executive with respect to one or more Annual Performance Rights during any calendar year during any part of which the 2007 Incentive Compensation Plan is in effect.

Prior to the grant of any Annual Performance Right, the Committee will determine the terms of the Annual Performance Right including:

·       The Target Award,

·       One or more Performance Goals to measure performance,

·       The Performance Formula to apply against the Performance Goals in determining the amount of compensation earned under the Performance Right as a percentage of the Target Award, and

·       The Performance Period (the period for which performance with respect to one or more Performance Goals is to be measured).

The Committee may establish a minimum threshold objective for any Performance Goal, which if not met, would result in no Final Award being made to any Participant with respect to the Performance Goal. During and after the Performance Period but prior to determination of the Final Award, the Committee may adjust the Performance Goals, Performance Formula and Target Award and

13

otherwise modify the terms of an Annual Performance Right but if the Committee acts, more than 90 days after the beginning of the Performance Period, to adjust or modify the terms of an Annual Performance Right granted to a participant who is a Covered Executive for purposes of Internal Revenue Code Section 162(m), the Annual Performance Right will not constitute performance-based compensation for purposes of Internal Revenue Code Section 162(m). Each Annual Performance Right will be evidenced by an award agreement in a form determined by the Committee.

As soon as practicable, following the completion of the Performance Period relating to any Annual Performance Right, the Committee will determine the extent to which the participant achieved the Performance Goals and the amount of compensation to be awarded as a Final Award. The Committee may in its sole discretion reduce the amount of any Final Award or increase the amount of any Final Award awarded to any participant, but if the Committee acts to increase the amount of the Final Award awarded to a participant who is a Covered Executive for purposes of Internal Revenue Code Section 162(m), the Final Award will not constitute performance-based compensation for purposes on Internal Revenue Code Section 162(m). Any determination shall take into account:

·       The extent to which the Performance Goals were, in the Committee’s sole opinion, achieved;

·       Individual performance by the participant during the performance period; and

·       Such other factors as the Committee may deem relevant, including changes in circumstances or unforeseen events.

The Final Award will be payable to the participant in cash unless the participant elects to defer its payment pursuant to the Integrys Energy Group Deferred Compensation Plan.

Performance Stock Rights and Final Awards:

The Committee may from time to time grant or authorize the granting of Performance Stock Rights to such Employees as the Committee may select and for such number of shares of Integrys Energy Group common stock as it may designate subject to the limitations specified in the 2007 Incentive Compensation Plan. A Performance Stock Right is the right to receive, without payment to Integrys Energy Group, up to the number of shares of Integrys Energy Group common stock described in the participant’s award agreement, taking into account the Target Award and the Performance Formula upon the attainment of one or more Performance Goals, subject to the terms of the award agreement and the 2007 Incentive Compensation Plan.

Prior to the grant of any Performance Stock Right, the Committee will determine the terms of the Performance Stock Right, including the Target Award, Performance Goal, Performance Formula and Performance Period. The Committee at any time prior to granting the Final Award will also determine the period of time, if any, during which the disposition of shares of Integrys Energy Group common stock issuable under the Performance Stock Rights will be restricted. The Committee may also determine that any participant will be entitled to receive Dividend Equivalents, i.e., payment of the same amount of cash or other credit in the same amount as he or she would have received as cash dividends during the Performance Period if the participant had owned the number of shares of Integrys Energy Group common stock equal to the Target Award. Dividend Equivalents may be paid in cash on dividend payment dates or at the time of the Final Award or in shares of Integrys Energy Group common stock, all as the Committee may determine in accordance with the applicable tax rules. Final Awards are made in the manner previously described with respect to Annual Performance Rights but are payable in shares of Integrys Energy Group common stock unless the participant elects to defer payment pursuant to the Integrys Energy Group Corporation Deferred Compensation Plan.

14

Options:

The Committee may from time to time authorize the granting of Options to officers and other employees as the Committee may select. Each Option will be a nonqualified stock option unless the Committee at the time of grant designates the Option as an “incentive stock option”(“ISO”) as such term is defined in Section 422 of the Internal Revenue Code.

Option Price:

The Committee will determine the per share option price which will be not less than the closing market price of Integrys Energy Group common stock on the date of the grant of the Option.

Option Period:

The Committee will determine the term of each Option. The term of an Option, however, may not exceed a period of ten (10) years from the date of its grant.

Exercise of Option:

Unless the Committee shall provide otherwise, the participant may make any payment for shares of Integrys Energy Group common stock purchased upon exercise of an Option granted under the 2007 Incentive Compensation Plan in cash, by delivery of shares of Integrys Energy Group common stock which have been beneficially owned by the participant for at least six months or by a combination of cash and stock, at the election of the participant. The Committee may also permit payment through a cashless exercise executed through a broker.

ISO’s Option Period Maximum Value:

Options, which are ISOs, may be exercised no later than three months after termination of employment by reason of death, early or normal retirement or total and permanent disability. The aggregate fair market value of the stock for which an ISO is exercisable for the first time by a participant during any calendar year under the 2007 Incentive Compensation Plan or any other plan of Integrys Energy Group or any subsidiary may not exceed $100,000. To the extent the fair market value of the shares of Integrys Energy Group common stock attributable to ISOs first exercisable in any calendar year exceeds $100,000, the excess portion of the ISO will be treated as a nonqualified option.

SARs:

Integrys Energy Group may grant SARs in tandem with Options or separate from any Option granted under the 2007 Incentive Compensation Plan. SARs entitle the participant to receive an amount equal to the excess of the closing market price of one share of Integrys Energy Group’s common stock on the date of exercise over the per share grant or option price multiplied by the number of shares in respect of which the participant exercises the SARs. If the Committee grants SARs independent of an Option, the grant price of the SARs will be not less than the closing market price of a share of Integrys Energy Group’s common stock on the date of grant multiplied by the number of shares subject to the SARs. Upon exercise of SARs, Integrys Energy Group generally will pay the participant in Integrys Energy Group common stock, although the 2007 Incentive Compensation Plan permits Integrys Energy Group to pay the participant in cash, Integrys Energy Group common stock or a combination of stock and cash.

In the case of a SAR issued in tandem with an Option, the total number of shares of Integrys Energy Group’s common stock that a participant may receive upon exercise of a SAR for stock may not exceed the total number of shares subject to the related Option or portion of Option. The total

15

amounts of cash that a participant may receive upon exercise of a SAR for cash (where an exercise for cash is permitted) may not exceed the closing market price on the date of exercise of the total number of shares subject to the related Option or portion of Option.

With respect to Options issued in tandem with SARs, the right of a participant to exercise the SAR will be cancelled if and to the extent the participant exercises the related Option, and the right of a participant to exercise an Option will be cancelled if and to the extent the participant exercises the related SAR.

Stock and Other Stock-Based Awards:

The Committee may from time-to-time grant to officers and other Employees as the Committee may select other stock-based awards which may include awards of restricted stock, “stock units,” phantom stock and options containing terms differing from options otherwise granted pursuant to the 2007 Incentive Compensation Plan. The Committee has authority to determine all terms and conditions of the other stock-based awards including whether the awards will be payable in cash, stock or otherwise.

Cash Awards to Employees of Foreign Subsidiaries, Branches or Joint Ventures:

The Committee may provide for special terms, including cash payments and other substitutes for the previously described awards under the 2007 Incentive Compensation Plan for participants who are foreign nationals or who are employed outside the United States of America to accommodate differences in local law, tax policy or custom.

Conditions to Payment of 2007 Incentive Compensation Plan Awards:

If a 2007 Incentive Compensation Plan participant’s employment terminates for any reason other than death, while any award to the participant under the Plan is outstanding and the participant has not received the compensation or stock covered by the award or the full benefit of the award, the participant will receive the remaining stock, compensation or benefit only if the participant continues to make himself or herself available upon request at reasonable times and on a reasonable basis to consult with, supply information to, and otherwise cooperate with Integrys Energy Group or any of its subsidiaries with respect to any matter previously handled by him or her or under his or her supervision and the participant refrains from engaging in any activity that is directly or indirectly in competition with any activity of Integrys Energy Group or any of its subsidiaries. The Committee may waive any forfeiture of 2007 Incentive Compensation Plan awards if it determines that there has not been and will not be any substantial adverse effect on Integrys Energy Group or any of its subsidiaries.

All rights of a participant under any award granted under the 2007 Incentive Compensation Plan will cease as of the date the Committee determines that the participant at any time acted in a manner inimical to Integrys Energy Group or any of its subsidiaries.

The Committee will make appropriate arrangements for deposit of any taxes and other required federal, state or local withholdings prior to distribution of cash, stock or other stock-based awards to any participant.

16

Transferability of Awards, Options and SARs:

No Annual Performance Right or Performance Stock Right, or until the expiration of any restriction period, no shares of Integrys Energy Group’s common stock covered by any Final Award may be transferred, pledged, assigned or otherwise disposed of by a participant except as permitted by the 2007 Incentive Compensation Plan, without the consent of the Committee, other than by will or the laws of descent and distribution. The Committee may permit the use of stock included in any Final Award as partial or full payment upon exercise of any stock option granted by Integrys Energy Group prior to the expiration of any restriction period relating to the Final Award.

Unless the Committee determines otherwise under the 2007 Incentive Compensation Plan, no Option or SAR or other stock-based award granted under the 2007 Incentive Compensation Plan may be transferred by a participant other than by will or the laws of descent and distribution, and during the lifetime of a participant any Option or SAR or other stock-based award granted under the 2007 Incentive Compensation Plan to a participant shall be exercisable only by the participant or his or her guardian or legal representative.

In no event may an Award, Option, SAR or other stock-based award be transferable for value or consideration.

A participant may file with Integrys Energy Group a written designation of a beneficiary or beneficiaries under the 2007 Incentive Compensation Plan subject to any limitations the Committee may from time to time prescribe.

Change in Control:

Unless the Committee determines otherwise at the time of grant, upon the occurrence of a Change in Control:

·       Any awards of Options or SARs outstanding under the 2007 Incentive Compensation Plan that are not vested will become fully vested;

·       Any other awards outstanding under the 2007 Incentive Compensation Plan that are not vested will become fully vested if vesting is based solely upon length of employment or in any other case will become fully vested at the Target Level (or if greater, the then projected Final Award) prorated for the portion of the Performance Period then elapsed, any restrictions or other conditions applicable to outstanding 2007 Incentive Compensation Plan awards will then lapse, and any of those awards will immediately be paid to the participant.

Except as otherwise required to comply with Internal Revenue Code Section 409A, Change of Control means the occurrence of any one of the following:

·       Any person (other than an employee benefit plan of Integrys Energy Group or of any subsidiary of Integrys Energy Group and fiduciaries and certain other parties related to any of these plans) becomes the beneficial owner of securities of Integrys Energy Group representing at least 30% of the combined voting power of Integrys Energy Group’s then outstanding securities;

·       One-half or more of the members of Integrys Energy Group’s board of directors ceases to be a “Continuing Director,” i.e., an individual who was a member of the board on the day following the effective date of the 2007 Incentive Compensation Plan, a successor to a Continuing Director who is recommended to succeed a Continuing Director by a majority of the Continuing Directors then on Integrys Energy Group’s board of directors or additional directors elected by a majority of the Continuing Directors;

·       Completion of any merger, consolidation or reorganization of Integrys Energy Group with any other corporation as a result of which less than 50% of the outstanding voting securities of the

17

surviving or resulting entity are owned by the former shareholders of Integrys Energy Group other than a shareholder who is an affiliate or associate of any party to such consolidation or merger;

·       Completion of any merger of Integrys Energy Group or share exchange involving Integrys Energy Group in which Integrys Energy Group is not the continuing or surviving corporation other than a merger of Integrys Energy Group in which each of the holders of Integrys Energy Group common stock immediately prior to the merger have the same proportional ownership of common stock of the surviving corporation immediately after the merger;

·       Completion of any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all or substantially all of the assets of Integrys Energy Group to a person other than a wholly owned subsidiary of Integrys Energy Group; or

·       Approval by the shareholders of Integrys Energy Group of any plan or proposal for the liquidation or dissolution of Integrys Energy Group.

Amendment and Termination:

The board of directors of Integrys Energy Group may, from time to time, amend or modify the 2007 Incentive Compensation Plan or any outstanding award under the 2007 Incentive Compensation Plan as necessary or desirable to implement Plan Awards or may terminate the 2007 Incentive Compensation Plan or any provision of the 2007 Incentive Compensation Plan. No such action of the board, however, without the approval of the shareholders of Integrys Energy Group, may:

·       Increase the total number of shares of Integrys Energy Group common stock with respect to which awards may be granted under the 2007 Incentive Compensation Plan or increase certain individual limits specified in the 2007 Incentive Compensation Plan;

·       Extend the terms of the 2007 Incentive Compensation Plan beyond May 16, 2017,

·       Permit any person while a member of the Compensation Committee or any other committee of the board administering the Plan to be eligible to receive or hold an award under the 2007 Incentive Compensation Plan; or

·       Permit Integrys Energy Group to “reprice” an outstanding Option or SAR to provide for a grant price that is less than the closing market price of a share of common stock on the date on which the Option or SAR was originally granted, cancel an Option or SAR and replace the cancelled Option or SAR with an Option or SAR having an exercise price or base price less than that of the cancelled Option or SAR, or make a cash payment in exchange for an Option or SAR if the closing market price of Integrys Energy Group common stock on the date of the proposed cash payment is less than the Option exercise price or SAR base price.

Accounting Treatment of Options

In accordance with Statement of Financial Accounting Standards (“SFAS”) No. 123R, Integrys Energy Group will recognize expense in connection with stock options and other share-based payments under the 2007 Incentive Compensation Plan.

Federal Income Tax Consequences

The federal income tax consequences described in this section are based on laws and regulations in effect on the date of this proxy statement and future changes in those laws and regulations may affect the tax consequences described below. No discussion of state income tax treatment has been included.

18

Nonqualified Stock Options:

Options granted under the 2007 Incentive Compensation Plan which do not qualify as ISOs will, in general, be subject to the following federal income tax treatment:

·       The grant of a nonqualified option does not give rise to any income tax consequences to either Integrys Energy Group or the participant.

·       The exercise of a nonqualified option generally results in ordinary taxable income to the participant in the amount equal to the excess of the fair market value of the shares at the time of exercise over the option price. A deduction from taxable income is allowed to Integrys Energy Group in an amount equal to the amount of ordinary income recognized by the participant.

·       Upon a subsequent taxable disposition of shares, a participant recognizes short-term or long-term capital gain (or loss) depending on the holding period, equal to the difference between the amount received and the tax basis of the shares, usually the fair market value at the time of exercise, net of any transaction costs.

Incentive Stock Options:

Options granted under the Plan which constitute ISOs will, in general, be subject to the following federal income tax treatment:

·       The grant of an ISO does not give rise to any income tax consequences to either Integrys Energy Group or the participant.

·       No deduction is allowed to Integrys Energy Group on a participant’s exercise of an ISO.

·       A participant’s exercise of an ISO does not result in ordinary income to the participant for regular tax purposes, but may result in the imposition of or an increase in alternative minimum tax. If shares acquired upon exercise of an ISO are not disposed of within the same taxable year of the ISO exercise, the excess of the fair market value of the shares at the time the ISO is exercised over the option price is included in the participant’s computation of alternative minimum taxable income in the year of exercise.

·       If shares acquired upon the exercise of an ISO are disposed of within two years of the date of the option grant, or within one year of the date of the option exercise, the participant recognizes ordinary taxable income at the time of the disposition to the extent that the fair market value of the shares at the time of exercise exceeds the option price, but not in an amount greater than the excess, if any, of the amount realized on the disposition over the option price. The participant recognizes capital gain (long-term or short-term depending upon the holding period) at the time of such a disposition to the extent that the amount of proceeds from the sale exceeds the fair market value at the time of the exercise of the ISO. The participant recognizes capital loss (long-term or short-term depending upon the holding period) at the time of such a disposition to the extent that the fair market value at the time of the exercise of the ISO exceeds the amount of proceeds from the sale. Integrys Energy Group is entitled to a deduction in the taxable year in which the disposition is made in an amount equal to the amount of ordinary income recognized by the participant.

·       If shares acquired upon the exercise of an ISO are disposed of after the later of two years from the date of the option grant or one year from the date of the option exercise in a taxable transaction, the participant recognizes long-term capital gain or loss at the time of the disposition in an amount equal to the difference between the amount realized by the participant on the disposition and the participant’s basis in the shares. Integrys Energy Group will not be entitled to any income tax deduction with respect to the ISO.

19

Stock Appreciation Rights:

Any SAR granted under the 2007 Incentive Compensation Plan, will in general, be subject to the following federal income tax treatment:

·       The grant of a SAR does not give rise to any income tax consequences to either Integrys Energy Group or the participant.

·       Upon the exercise of a SAR, the participant recognizes ordinary income equal to the amount of any cash plus the fair market value of any shares of common stock received. Integrys Energy Group is generally allowed a deduction in an amount equal to the income recognized by the participant.

Annual Performance Rights and Performance Stock Rights:

Any Annual Performance Right or Performance Stock Right granted under the 2007 Incentive Compensation Plan will, in general, be subject to the following federal income tax treatment:

·       The grant of an Annual Performance Right or Performance Stock Right does not give rise to any tax consequences to either Integrys Energy Group or the participant.

·       Upon payment of cash pursuant to an Annual Performance Right, the participant recognizes ordinary income equal to the amount of the payment and Integrys Energy Group is generally allowed a deduction in an equal amount.

·       Upon the issuance of Integrys Energy Group’s common stock pursuant to a Performance Stock Right, generally the participant recognizes ordinary income equal to the fair market value of the shares received, or if received subject to certain restrictions, the fair market value of the shares when no longer restricted. The participant recognizes ordinary income on the receipt of Dividend Equivalents.

·       A deduction from taxable income is allowed to Integrys Energy Group in an amount equal to the amount of ordinary income recognized by the participant with respect to the Performance Stock Right.

Internal Revenue Code Sections 162(m) and 280G:

Section 162(m) of the Internal Revenue Code limits Integrys Energy Group income tax deduction for compensation paid in any taxable year to certain executive officers to $1 million per individual. Amounts in excess of $1 million are not deductible unless one of several exceptions apply. The Committee intends to grant awards under the 2007 Incentive Compensation Plan that are designed, in most cases and with the specific exception of Other Stock Rights (such as restricted stock) that are subject to time-based vesting, to qualify for one such exception, the performance-based compensation exception. Grants of Options and SARs as well as Annual Performance Rights and Performance Stock Rights can be structured so as to qualify for this exception. Integrys Energy Group does not anticipate that Section 162(m) will have a material impact on its ability to deduct compensation payable under the 2007 Incentive Compensation Plan, but the Committee specifically reserves the right to make awards that are not intended to comply with Section 162(m). Section 280G of the Internal Revenue Code limits Integrys Energy Group income tax deduction in the event there is a change in control of Integrys Energy Group. Accordingly, all or some of the amount which would otherwise be deductible may not be deductible with respect to those Annual Performance Rights, Performance Stock Rights, Options and SARs that become immediately exercisable or payable in the event of a change in control of Integrys Energy Group.

20

Other Disclosures

Market Price of Common Stock:

The closing price of a share of Integrys Energy Group common stock on the New York Stock Exchange on March 23, 2007 was $55.70.

New Plan Benefits:

The number and amount of awards under the 2007 Incentive Compensation Plan has yet to be determined. The Committee pursuant to the terms of the 2007 Incentive Compensation Plan will determine the number and nature of the 2007 Incentive Compensation Plan awards. In 2006, 188 employees received grants under the 2005 Omnibus Incentive Compensation Plan. See “Grants of Plan-Based Awards” for information relating to the performance shares, restricted stock and stock options rights granted to Integrys Energy Group’s Chief Executive Officer, Chief Financial Officer and its three most highly compensated executive officers.

Required Vote:

The affirmative vote of a majority of the votes cast on the proposal by the holders of Integrys Energy Group common stock is required for approval and ratification of the Plan, provided that a majority of the outstanding shares of Integrys Energy Group common stock are voted on the proposal. Any shares not voted (whether by abstention, broker nonvote or otherwise) may prevent the proviso from being satisfied, but if the proviso is satisfied, will have no impact on the vote.

The board recommends that you vote “FOR” the approval of the Integrys Energy Group 2007 Omnibus Incentive Compensation Plan. Proxies solicited by the board of directors will be voted “FOR” approval and ratification of the proposed 2007 Omnibus Incentive Compensation Plan unless the shareholder has specified otherwise.

21

APPROVAL OF PROPOSED AMENDMENT TO INCREASE COMMON STOCK
AVAILABLE UNDER THE INTEGRYS ENERGY GROUP
DEFERRED COMPENSATION PLAN

Integrys Energy Group maintains the Integrys Energy Group Deferred Compensation Plan (the “Deferred Compensation Plan”). The board of directors of Integrys Energy Group will adopt an amendment to the Deferred Compensation Plan to increase the number of shares of Common Stock available for issuance under the Deferred Compensation Plan, subject to approval by the holders of Common Stock at the Integrys Energy Group 2007 Annual Meeting of Shareholders.

The following summary description of the Deferred Compensation Plan is subject in all respects to the full text of the Deferred Compensation Plan. A copy of the Deferred Compensation Plan will be furnished without charge to any person entitled to receive a copy of Integrys Energy Group’s Form 10-K upon written request to Integrys Energy Group, Attention: Peter H. Kauffman, Secretary and Chief Governance Officer, 130 East Randolph Drive, Chicago, Illinois 60601.

The Deferred Compensation Plan permits key employees of Integrys Energy Group and its subsidiaries and affiliates to defer a portion of their base compensation, as well as annual bonus awards and long-term performance awards under the Integrys Energy Group 2005 Omnibus Incentive Compensation Plan (the “2005 Incentive Compensation Plan”) and the Integrys Energy Group 2007 Omnibus Incentive Compensation Plan (the “2007 Incentive Compensation Plan”) and in most cases, to allocate the amount deferred among the hypothetical investment accounts available under the Deferred Compensation Plan. The accounts are bookkeeping accounts, which serve solely as a device for determining the amount of benefits accumulated by a participant and do not create or imply an obligation on the part of Integrys Energy Group to fund such benefits. In addition, the Deferred Compensation Plan includes both mandatory and voluntary components for the directors of Integrys Energy Group.

22

23

Hypothetical investment accounts are established as devices for determining the amount of benefits accumulated by a participating employee or director under the Deferred Compensation Plan and prior deferred compensation programs, including the following accounts:

Reserve Account A has been credited with the reserve account balance accumulated by a participating employee or director as of December 31, 1995, under a prior deferred compensation program of Wisconsin Public Service Corporation. Except for attributed earnings, no further contributions or credits of any kind will be made to this account. Balances of participating employees or directors in Reserve Account A are credited with an interest equivalent for each month at a rate equal to the greater of (i) 0.5% or (ii) 1/12th of the consolidated return on equity of Integrys Energy Group and all of its consolidated subsidiaries (“ROE”) for the 12 month period ended on the preceding September 30 for the months of January through March and October through December and for the 12 month period ended on the preceding March 31 for the months of April through September. Alternative (ii) will not apply following termination of employment to a participating employee who terminates employment with a participating employer prior to age 55 and prior to a change of control as defined below, unless the Committee determines otherwise.

Reserve Account B is credited with that portion of deferrals of base compensation and annual bonus awards which a participating employee or director elects to allocate to this account. Participant balances in Reserve Account B will be credited with an interest equivalent for each month at a rate equal to the greater of (i) 0.5% or (ii) 70% of 1/12th of the ROE for the 12 month period ended on the preceding September 30 for the months of January through March and October through December and for the 12 month period ended on the preceding March 31 for the months of April through September. Alternative (ii) will not apply following termination of employment to a participating employee who terminates employment with a participating employer prior to age 55 and prior to a change of control as defined below, unless the Committee determines otherwise.

The Committee may revise the interest equivalent rate for Reserve Accounts A and B or the manner in which such rate is calculated, but may not reduce the rate below 6% per annum.

Incentive Stock Unit Account is a “buy only” account limited to that portion of deferrals of annual bonus awards which the participating employee elects to allocate to this account, deferrals of performance share awards under the 2005 Incentive Compensation Plan or the 2007 Incentive

24

Compensation Plan, Matching Contribution Credits, and/or Other Employer Credits. A participating employee is not permitted to reallocate amounts that are credited to the Incentive Stock Unit Account to any of the other hypothetical investment accounts.

Base Stock Unit Account is credited with that portion of a deferral of base compensation which a participating employee elects to allocate to this account.

Deferrals to the Incentive Stock Unit Account and the Base Stock Unit Account, dividends credited on stock units and any Matching Contribution Credits, will be converted for record keeping purposes, into whole and fractional stock units with fractional units calculated to four decimal places based on the closing price of Integrys Energy Group common stock as reported in the New York Stock Exchange Composite Transactions in The Wall Street Journal on the date the deferrals are credited to a participant’s account. Participating employees electing to allocate deferrals to, or otherwise receiving credits under, the two stock accounts will have no rights of a shareholder resulting from the stock units in their accounts. Integrys Energy Group may, however, elect to have shares of Company common stock purchased by the Trust in an amount equal to a portion of the stock units in the stock accounts. Although participants under the Deferred Compensation Plan will have no proprietary interest in shares purchased by the Trust and will remain general unsecured creditors of Integrys Energy Group with respect to amounts deferred under the Deferred Compensation Plan, shares held by the Trust for purposes of exercising voting rights are allocated proportionately to the share units in the respective stock accounts of participating employees and voted in accordance with the instructions of such participants.

Director Deferred Stock Unit Account is a “buy only” account limited to the portion of a director’s fees that is automatically converted into Integrys Energy Group Stock Units. A director is not permitted to reallocate amounts credited to the Director Deferred Stock Unit Account to any of the other hypothetical investment options.

The Committee has established certain other hypothetical investment accounts. Such accounts generally mirror investment options available to the participating employee under Wisconsin Public Service Corporation’s 401(k) savings plan.

Elections to defer base compensation or director fees generally must be made prior to the beginning of the calendar year in which the deferred amount would otherwise be paid. Elections to defer annual bonus awards must be made each year on or before June 30 (or such earlier date as may be established by the Committee). Elections to defer long-term performance incentive awards must be made at least six months prior to the end of the performance period (or such earlier date as may be established by the Committee). The Committee may establish additional requirements with respect to the form and timing of deferral elections.

In accordance with Committee rules, participating employees and directors may elect to reallocate how deferred amounts are deemed to be invested. The right to reallocate the deemed investment of deferred amounts does not apply to amounts deferred by certain participants prior to July 1, 2001, and does not apply with respect to any amounts credited to the Incentive Stock Unit Account or the Director Deferred Stock Unit Account.

All reallocation elections by a participant who is subject to Section 16 of the Exchange Act of 1934 (“Exchange Act”), however, are subject to review by the Committee prior to implementation. In addition, the following transactions are prohibited: elections to reallocate the deemed investments into Integrys Energy Group Stock Units within six months of an election to reallocate deemed investments out of Integrys Energy Group Stock Units and elections to reallocate the deemed investments out of Integrys Energy Group Stock Units within six months of an election to reallocate deemed investments into Integrys Energy Group Stock Units. These prohibited transactions are void. The Committee may

25

restrict additional transactions, or impose other rules and procedures, to the extent deemed desirable by the Committee in order to comply with the Exchange Act.

It is not possible to predict what benefits will be received under the Deferred Compensation Plan, as amended. For information on 2006 deferrals and earnings in this plan for the named executive officers see the tables regarding Nonqualified Deferred Compensation later in this proxy. In 2006 total dollars deferred and income earned in this plan were $3,603,362 and $765,283, respectively. The total number of stock units deferred into the plan in 2006 was 87,051.

Distributions from Deferred Compensation Plan accounts are made in 1 to 15 annual installments, as elected by the participating employee or director and commence within 60 days following the end of the calendar year in which occurs the 6-month anniversary of the participating employee’s retirement or termination of employment or the director’s termination of service, unless the employee or director has selected a later commencement date. A participating employee or director may modify a distribution election but such revision will take effect only if certain conditions are satisfied. With respect to amounts deferred prior to January 1, 2005, the revised distribution election will take effect only if the participant remains employed by Integrys Energy Group or a subsidiary or affiliate of Integrys Energy Group for 12 consecutive months following the revised election. With respect to amounts deferred after December 31, 2004, a revised distribution election is permitted only if the participant is deferring distribution commencement for at least five years. For purposes of determining distribution amounts, share units in the Stock Accounts will be valued on the basis of the closing price as reported in The Wall Street Journal as New York Stock Exchange Composite Transactions on January 21 (or if not a trading day the next preceding trading day) of each year.

Distributions attributable to a participant’s stock accounts will be made in whole shares of common stock of Integrys Energy Group. Distributions attributable to Reserve Account A and Reserve Account B and other hypothetical investment accounts will be made in cash. Unless a participant otherwise elects, income tax on each distribution will be withheld from the cash portion of the distribution and Integrys Energy Group common stock will be used to satisfy withholding obligations only to the extent that the cash portion of the distribution is insufficient.

The amended Deferred Compensation Plan provides that, subject to adjustment as described below, the total number of authorized but previously unissued shares of common stock of Integrys Energy Group which may be distributed to participants pursuant to the Deferred Compensation Plan is 1,450,000, which number is not reduced by or as a result of (i) any cash distributions pursuant to the Deferred Compensation Plan or (ii) the distribution to participants pursuant to the Deferred Compensation Plan of shares of common stock of Integrys Energy Group that relate to an award of shares originally made (and charged against the pool of available shares) under the 2005 Incentive Compensation Plan or the 2007 Incentive Compensation Plan. Of the 1,450,000 total shares, 750,000 represent shares already approved by shareholders and 700,000 represent additional shares to be available upon the approval of shareholders at Integrys Energy Group’s 2007 annual meeting. In the event of any merger, reorganization, consolidation, recapitalization, separation, liquidation, stock dividend, split-up, share combination or other change in the corporate structure of Integrys Energy Group affecting its common stock, adjustment will be made in the number and class of shares which may be distributed pursuant to the Deferred Compensation Plan as may be determined to be appropriate and equitable by the Committee in its sole discretion.

RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committee selected Deloitte & Touche LLP, independent registered public accounting firm, to audit the consolidated financial statements of Integrys Energy Group and its subsidiaries for the year ending December 31, 2007, as well as its internal control over financial reporting as of December 31, 2007 and requests that the shareholders ratify such selection. If shareholders do not ratify the selection of Deloitte & Touche LLP, the audit committee will reconsider the selection.

Audit services provided by Deloitte & Touche in 2006 included the audit of the consolidated financial statements of Integrys Energy Group and its subsidiaries; reviews of interim condensed consolidated financial statements; audit of management’s assessment that Integrys Energy Group maintained effective internal control over financial reporting and Integrys Energy Group’s internal control over financial reporting as of December 31, 2006 and consultations on matters related to accounting and financial reporting.

Deloitte & Touche also provided certain audit related and nonaudit services to Integrys Energy Group and its subsidiaries during 2006, which were reviewed by the audit committee and are more fully described later in this proxy statement.

Representatives of Deloitte & Touche are expected to attend the annual meeting where they will be available to respond to questions and, if they desire, to make a statement.

Assuming a quorum is present at the annual meeting, to ratify the Audit Committee’s selection of Deloitte & Touche as the independent registered public accounting firm for 2007, the number of votes cast in favor of ratification must exceed the number of votes cast in opposition to it. Abstentions and broker non-votes will be counted as present in determining whether there is a quorum; however, they will not constitute a vote “for” or “against” ratification, and will be disregarded in the calculation of “votes cast.” A “broker non-vote” occurs when a broker submits a proxy card with respect to shares that the broker holds on behalf of another person, but declines to vote on a particular matter, either because the broker elects not to exercise its discretionary authority to vote on the matter or does not have authority to vote on the matter.

The board of directors recommends a vote “FOR” the ratification of the selection of Deloitte & Touche LLP as the independent registered public accounting firm for Integrys Energy Group and its subsidiaries for 2007. Proxies solicited by the board of directors will be voted “FOR” ratification of the selection of Deloitte & Touche LLP as the independent registered public accounting firm for Integrys Energy Group and its subsidiaries for 2007.

BOARD COMMITTEES

Committee Membership

The following table lists the board committees, their members as of December 31, 2006, and the number of board and board committee meetings in 2006.

In 2006, all directors attended a minimum of 75 percent of the aggregate number of (1) all board meetings and (2) their assigned committee meetings. Under Integrys Energy Group’s Corporate Governance Guidelines all directors are expected to attend the annual meeting of shareholders. All directors (with the exception of Richard A.

The board of directors selected Robert C. Gallagher, to serve as lead director, for a one-year term, effective January 1, 2007. Upon the close of the merger with Peoples Energy, James R. Boris, an independent director, was appointed Non-Executive Chairman and Robert C. Gallagher resigned as lead director. As the independent Non-Executive Chairman, Mr. Boris will preside at all executive sessions of the non-management directors.

Any shareholder or interested party wishing to communicate with the chairman may contact Mr. Boris by sending a written communication, addressed to the chairman, in care of Integrys Energy Group’s Secretary and Chief Governance Officer, Integrys Energy Group, Inc., 130 East Randolph Drive, Chicago, Illinois 60601.

Audit Committee

At December 31, 2006, the audit committee consisted of four independent directors of Integrys Energy Group: James L. Kemerling - Chairperson, Albert J. Budney, Jr., Ellen Carnahan and William F. Protz, Jr. On February 21, 2007, upon the closing of the merger with Peoples Energy, the Audit Committee was reappointed by the Board with James L. Kemerling, Ellen Carnahan, William F. Protz, Jr., Michael E. Lavin - Chairperson and Diana S. Ferguson as the members of the Audit Committee. The Integrys Energy Group board of directors has determined that all five members meet audit committee financial expert requirements as defined by the Securities and Exchange

30

Commission (“SEC”). Diana S. Ferguson currently serves on the Audit Committee of Franklin Electric Co., Inc. and Michael E. Lavin currently serves on the Audit Committees of Tellabs, Inc and SPSS Inc. None of the remaining members of the Integrys Energy Group audit committee are members of any other public company’s audit committee.

Integrys Energy Group’s securities are listed on the New York Stock Exchange and are governed by its listing standards. All members of the audit committee meet the independence standards of Section 303.01(B)(2) and (3) of the listing standards of the New York Stock Exchange and Section 10A-3 under the Securities Exchange Act of 1934. In compliance with NYSE listing standards, in 2006 the audit committee received an annual report of the independent auditors regarding the internal control over financial reporting of Integrys Energy Group.

The audit committee is directly responsible for the selection, compensation and oversight of Deloitte & Touche LLP as its independent registered public accounting firm. Deloitte & Touche reports directly to the audit committee. The committee is responsible to oversee the resolution of any disagreements between Deloitte & Touche and management.

A written charter defining the responsibilities of the audit committee has been adopted.

The information contained in this proxy statement with respect to the audit committee charter shall not to be deemed to be “soliciting material” or deemed to be filed with the SEC, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent specifically requested by Integrys Energy Group or incorporated by reference in documents otherwise filed.

Principal Fees and Services Paid to Independent Registered Public Accounting Firm

The following is a summary of the fees billed to Integrys Energy Group by Deloitte & Touche LLP for professional services performed for 2006 and 2005:

a)                Audit Fees. Consists of aggregate fees billed to Integrys Energy Group and its subsidiaries by Deloitte & Touche LLP for professional services rendered for the audits of the annual consolidated financial statements, reviews of the interim condensed consolidated financial statements included in quarterly reports and audits of the effectiveness of, and management’s assessment of the effectiveness of, internal control over financial reporting, of Integrys Energy Group and its subsidiaries. Audit fees also include services that are normally provided by Deloitte & Touche in connection with statutory and regulatory filings or engagements, including comfort letters, consents and other services related to SEC matters, and consultations arising during the course of the audits and reviews concerning financial accounting and reporting standards.

b)               Audit Related Fees. Consists of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of the consolidated financial statements or internal control over financial reporting and are not reported under “Audit Fees.” These services include employee benefit plan audits, accounting consultations in connection with potential

31

transactions, due diligence projects, and consultations concerning financial accounting and reporting standards.

c)                All Other Fees. Consists of other fees billed to Integrys Energy Group and its subsidiaries by Deloitte & Touche LLP for products and services other than the services reported above. All Other Fees are for software licensing and training provided in 2006 and 2005. The nature of the software license fees, which include support, learning services, and training have been deemed to be permissible non-attest services.

In considering the nature of the services provided by the independent registered public accounting firm, the audit committee determined that such services are compatible with the provision of independent audit services. The audit committee discussed these services with the independent registered public accounting firm and Integrys Energy Group’s management and determined that they are permitted under the rules and regulations concerning auditor independence promulgated by the SEC to implement the Sarbanes-Oxley Act of 2002, as well as those of the American Institute of Certified Public Accountants.

The audit committee has approved in advance 100% of the services described in the table above under “Audit Fees,” “Audit-Related Fees” and “All Other Fees” in accordance with its pre-approval policy.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm

Consistent with SEC policies regarding auditor independence, the audit committee has responsibility for appointing, setting compensation and overseeing the work of the independent registered public accounting firm. In recognition of this responsibility, the audit committee has established a policy regarding the pre-approval of all audit and permissible non-audit services provided by the independent registered public accounting firm.

The audit committee will annually pre-approve a list of select services and a maximum fee per engagement for these services that would not require management to obtain specific approval from the committee on an individual basis. Other services (not on the pre-approved list or individual engagements for services on the pre-approved list that exceed the dollar limit) would require additional approval of the audit committee. If pre-approval is necessary between audit committee meetings, the audit committee Chairperson or his designated alternate may provide approval. The audit committee may specifically delegate its pre-approval authority to the Chairperson and any audit committee member designated as an alternate. Approvals provided by any member to whom authority is delegated must be presented to the full audit committee at its next scheduled meeting. Integrys Energy Group’s external auditors are absolutely prohibited from performing certain non-audit services, including:

·       Bookkeeping or other services related to the accounting records or financial statements;

·       Financial information systems design and implementation;

·       Appraisal or valuation services, fairness opinions, or contribution-in-kind reports;

·       Actuarial services;

·       Internal audit outsourcing services;

·       Management functions or human resources;

·       Broker-dealer, investment advisor or investment banking services;

·       Legal and expert services unrelated to the audit; and

·       Other services the Public Company Accounting Oversight Board chooses to prohibit.

On February 21, 2007, upon the closing of the merger with Peoples Energy, the Financial Committee was reappointed by the Board with Robert C. Gallagher - Chairperson, James L. Kemerling, and Keith E. Bailey appointed as members of the Financial Committee. The committee acts in an advisory and consulting capacity to management regarding capitalization, dividend and investment policies and other financial matters.

Governance Committee

On December 31, 2006, the governance committee consisted of three independent directors; Albert J. Budney, Jr. - Chairperson, Robert C. Gallagher and Kathryn M. Hasselblad-Pascale.

Budney, Jr - Chairperson, Kathryn Hasselblad-Pascale and Pastora San Juan Cafferty appointed by the Board as members of the Governance Committee. Each individual met the independence requirements as defined in the New York Stock Exchange listing standards.

The committee provides oversight on the broad range of issues surrounding composition, operation and compensation of the board of directors, identifying and recommending individuals qualified to become board members and recommending corporate governance guidelines for Integrys Energy Group to the board of directors. The governance committee will consider individuals recommended by shareholders for nomination as a director. Recommendations for consideration by the governance committee should be sent to the Secretary and Chief Governance Officer, Integrys Energy Group, Inc., 130 East Randolph Drive, Chicago, Illinois 60601, together with appropriate biographical information concerning each proposed nominee. As provided in the Integrys Energy Group By-laws, any proposed nominees and appropriate biographical information must be submitted to the Secretary and Chief Governance Officer between January 26, 2008 and February 20, 2008, for consideration at the 2008 annual meeting. For more detailed information regarding the process to submit an individual for consideration as a director nominee and the qualifications necessary to become a director of Integrys Energy Group, shareholders should review our By-laws, corporate governance guidelines and the governance committee charter.

In identifying potential nominees and determining which nominees to recommend to the board of directors, the governance committee may retain the services of a professional search firm or other third party advisor. In connection with each vacancy, the committee will develop a specific set of ideal

33

characteristics for the vacant director position. The committee will look at nominees it identifies and any nominees identified by shareholders on an equal basis using these characteristics and the general criteria identified below.

The governance committee selects nominees on the basis of knowledge, experience, skills, expertise, diversity, personal and professional integrity, business judgment, time availability in light of other commitments, absence of conflicts of interest and such other relevant factors that the committee considers appropriate in the context of the needs of the board of directors at that time. At a minimum, each director nominee must have displayed the highest personal and professional ethics, integrity, values and sound business judgment. When considering nominees, the committee seeks to ensure that the board of directors as a whole possesses, and individual members possess at least one of the following competencies: (1) accounting and finance, (2) business judgment, (3) management, (4) industry knowledge, (5) leadership and (6) strategy/vision. In addition, the governance committee assures that at least one director have the requisite experience and expertise to be designated as an “audit committee financial expert.” The committee looks at each nominee on a case-by-case basis regardless of who recommended the nominee. In screening director nominees, the committee will review potential conflicts of interest, including interlocking directorships and substantial business, civic and social relationships with other members of the board of directors that could impair the prospective nominee’s ability to act independently.
