**AMENDED
      AND RESTATED**


**CHANGE-IN-CONTROL
      AGREEMENT**




THIS
      AGREEMENT dated as of December 18, 2007 (the “Agreement Date”) is made by and
      among Nicor Inc. (the “Company”), an Illinois corporation, and Richard L. Hawley
      (the “Executive”).




Executive
      and the Company have previously entered into a Change-in-Control Agreement
      dated
      December 8, 2003 (the “Prior Agreement”). The Company and Executive desire to
      amend and restate the Prior Agreement to conform to the requirements of Section
      409A of the Code.




**ARTICLE
      I**


**PURPOSES**




The
      Board
      has determined that it is in the best interests of the Company and its
      shareholders to assure that the Company and Nicor Gas will have the continued
      services of the Executive, despite the possibility or occurrence of a Change
      in
      Control of the Company. The Board believes it is imperative to reduce the
      distraction of the Executive that would result from the personal uncertainties
      caused by a pending or threatened Change in Control, to encourage the
      Executive’s full attention and dedication to the Company and Nicor Gas, and to
      provide the Executive with compensation and benefits arrangements upon a Change
      in Control which are competitive with those of similarly situated corporations.
      This Agreement is intended to accomplish these objectives.




**ARTICLE
      II**


**CERTAIN
      DEFINITIONS**




When
      used
      in this Agreement, the terms specified below shall have the following
      meanings:




**2.1.**  The
      “Agreement Term” shall begin on the Agreement Date and shall continue through
      December 31, 2008. As of December 31, 2008, and on each
      December 31 thereafter, the Agreement Term shall automatically be extended
      for one additional year unless, not later than the preceding June 30,
      either party shall have given notice that such party does not wish to extend
      the
      Agreement Term. If a Change in Control shall have occurred during the Agreement
      Term (as it may be extended from time to time), the Agreement Term shall
      continue for a period ending on the two-year anniversary of the date of the
      Change in Control, but if the Termination Date (as defined below) occurs during
      that two-year period, then the Agreement Term shall continue until the end
      of
      the Severance Period (as defined below). Unless the Termination Date occurs
      during the two-year period after a Change in Control so that the Agreement
      Term
      is extended to include the Severance Period, as provided in the immediately
      preceding sentence, the Agreement Term shall not extend beyond the two-year
      anniversary of the Change in Control.




**2.2.**  “Board”
      means the board of directors of the Company.




1


**2.3.**  “Change
      in Control” means the occurrence of a “change in the ownership,” a “change in
      the effective control” or a “change in the ownership of a substantial portion of
      the assets” of an entity, as determined in accordance with this Section. In
      determining whether an event shall be considered a “change in the ownership,” a
“change in the effective control” or a “change in the ownership of a substantial
      portion of the assets” of an entity, the following provisions shall
      apply:




**2.3.1**  A
“change
      in the ownership” of the Company shall occur on the date on which any one
      person, or more than one person acting as a group (within the meaning of Section
      13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (a
      “Person”)), acquires ownership of the equity securities of the Company that,
      together with the equity securities held by such Person, constitutes more than
      50% of the total fair market value or total voting power of the Company, as
      determined in accordance with Treas. Reg. §1.409A-3(i)(5)(v). If a Person is
      considered either to own more than 50% of the total fair market value or total
      voting power of the equity securities of the Company, or to have effective
      control of the Company within the meaning of Section 2.3.2, and such Person
      acquires additional equity securities of the Company, the acquisition of
      additional equity securities by such Person shall not be considered to cause
      a
“change in the ownership” of the Company.




**2.3.2**  A
“change
      in the effective control” of the Company shall occur on either of the following
      dates:




**2.3.2.1**  The
      date
      on which any Person, acquires (or has acquired during the 12-month period ending
      on the date of the most recent acquisition by such Person) ownership of stock
      of
      the Company possessing 30% or more of the total voting power of the Company’s
      equity securities, as determined in accordance with Treas. Reg.
§1.409A-3(i)(5)(vi). If a Person is considered to possess 30% or more of the
      total voting power of the Company’s equity securities, and such Person acquires
      additional stock of the Company, the acquisition of additional stock by such
      Person shall not be considered to cause a “change in the effective control” of
      the Company; or




**2.3.2.2**  The
      date
      on which a majority of the members of the Board is replaced during any 12-month
      period by directors whose appointment or election is not endorsed by a majority
      of the members of the Board before the date of the appointment or election,
      as
      determined in accordance with Treas. Reg. §1.409A-3(i)(5)(vi).




**2.3.3**  A
“change
      in the ownership of a substantial portion of the assets” of the Company shall
      occur on the date on which any one Person acquires (or has acquired during
      the
      12-month period ending on the date of the most recent acquisition by such
      Person) assets from the Company that have a total gross fair market value equal
      to or more than 40% of the total gross fair market value of all of the assets
      of
      the Company immediately before such acquisition or acquisitions, as determined
      in accordance with Treas. Reg. §1.409A-3(i)(5)(vii). A transfer of assets shall
      not be treated as a “change in the ownership of a substantial portion of the
      assets” when such transfer is made to an entity that is controlled by the
      holders of the Company’s equity securities, as determined in accordance with
      Treas. Reg. §1.409A-3(i)(5)(vii)(B).




2


**2.3.4**  Notwithstanding
      the foregoing, the following acquisitions shall not constitute a Change in
      Control: (i) an acquisition by the Company or entity controlled by the Company,
      or (ii) an acquisition by an employee benefit plan (or related trust) sponsored
      or maintained by the Company or any entity controlled by the Company.

      Inc. and shall include any Successor to Nicor Inc.; and (ii) the term
“Successor to Nicor Inc.” shall mean any corporation, partnership, joint venture

      merger, consolidation, or other restructuring that does not constitute a Change
      in Control.

      Date” means the first date during the Agreement Term on which a Change in

      Date” means the date on which all of the following are complete (i) the
      Termination Date, (ii) the execution of the release required pursuant to Section

      “Potential Change in Control” shall exist during any period in which the
      circumstances described in Sections 2.10.1, 2.10.2, or 2.10.3 exist
      (provided, however, that a Potential Change in Control shall cease to exist
      not
      later than the occurrence of a Change in Control):




**2.10.1**  The
      Company enters into an agreement, the consummation of which would result in
      the
      occurrence of a Change in Control, provided that a Potential Change in Control
      described in this Section 2.10.1 shall cease to exist upon the expiration
      or other termination of all such agreements.

      person (including the Company) publicly announces an intention to take or to

      Section 2.10.2 shall cease to exist upon the withdrawal of such intention,
      or upon a reasonable determination by the Board that there is no reasonable
      chance that such actions would be consummated.

      Company hereby agrees to cause the Company and/or Nicor Gas to continue the
      Executive’s employment during the Employment Period and, subject to
      Article IV of this Agreement, the Executive agrees to remain in the employ
      of the Company and Nicor Gas, as applicable, subject to the terms and conditions
      hereof. During the Employment Period, (i) the Executive’s position
      (including status, offices, titles and reporting requirements), authority,
      duties and responsibilities shall be at least commensurate in all material
      respects with the most significant of those held, exercised and assigned to
      the
      Executive at any time during the 90-day period immediately preceding the
      Effective Date, and (ii) the Executive’s services shall be performed at the
      location where the Executive was employed immediately preceding the Effective
      Date or any office or location less than 25 miles from such
      location.




**3.1.2**      
      During the Employment Period, and excluding any periods of vacation and sick
      leave to which the Executive is entitled, the Executive agrees to devote
      reasonable




4
 
 attention
        and time during normal business hours to the business and affairs of the
        Company
        and Nicor Gas, as applicable, and, to the extent necessary to discharge the
        responsibilities assigned to the Executive hereunder, to use the Executive’s
        reasonable best efforts to perform faithfully and efficiently such
        responsibilities. During the Employment Period it shall not be a violation
        of
        this Agreement for the Executive (i) to serve on corporate, civic or
        charitable boards or committees, (ii) to deliver lectures, fulfill speaking
        engagements or teach at educational institutions and (iii) to manage
        personal investments, to the extent that such other activities do not, in
        the
        reasonable judgment of the Chief Executive Officer of the Company (the “CEO”), inhibit or prohibit the
        performance of the Executive’s duties under this Agreement, or conflict in any
        material way with the business of the Company or any Subsidiary; provided,
        however, that the Executive shall not serve on the board of any business,
        or
        hold any other position with any business, without the consent of the
        CEO.




**3.2.** **Compensation** .




**3.2.1**  Base
      Salary .
      During
      the Employment Period, the Executive shall receive an annual base salary
      (“Annual Base Salary”), which shall be paid at an annual rate at least equal to
      twelve times the highest monthly base salary paid or payable, including any
      base
      salary which has been earned but deferred, to the Executive by the Company
      in
      respect of the twelve-month period immediately preceding the month in which
      the
      Effective Date occurs. During the Employment Period, the Annual Base Salary
      shall be reviewed no more than twelve months after the last salary increase
      awarded to the Executive prior to the Effective Date and, thereafter, at least
      annually, and shall be increased at any time and from time to time as shall
      be
      substantially consistent with increases in base salary awarded to other senior
      executives of the Company. Annual Base Salary shall not be reduced after any
      such increase unless such reduction is part of a policy, program or arrangement
      applicable to senior executives of the Company and of any successor entity,
      and
      the term Annual Base Salary as used in this Agreement shall refer to Annual
      Base
      Salary as so increased. Any increase in Annual Base Salary shall not limit
      or
      reduce any other obligation of the Company to the Executive under this
      Agreement.




**3.2.2**  Annual
      Incentive **.** In
      addition to Annual Base Salary, the Company shall pay or cause to be paid to
      the
      Executive an incentive award (the “Annual Incentive”) for each Performance
      Period or portion thereof which falls within the Employment Period. “Performance
      Period” means each period of time designated in accordance with any annual
      incentive award arrangement (“Incentive Plan”) which is based upon performance
      and approved by the Board or any committee of the Board, or in the absence
      of
      any Incentive Plan or any such designated period of time, Performance Period
      shall mean each calendar year. The Executive’s target and maximum Annual
      Incentive with respect to any Performance Period shall not be less than the
      target and maximum annual incentive award payable with respect to the Executive
      under the Company’s annual incentive program as in effect immediately preceding
      the Effective Date.




**3.2.3**  Incentive,
      Savings and Retirement Plans .
      During

      Nicor Inc. Stock Deferral Plan) (“Plans”) applicable generally to other senior
      executives of the Company, but in no event shall such Plans provide the
      Executive with incentive




5
 
 opportunities
        (measured with respect to long-term and special incentives, to the extent,
        if
        any, that such distinctions are applicable) or savings and retirement benefits
        which are less favorable, in the aggregate, than the greater of (i) those
        provided by the Company for the Executive under such Plans as in effect at
        any
        time during the 90-day period immediately preceding the Effective Date, or
        (ii) those provided generally at any time after the Effective Date to other
        senior executives of the Company.




**3.2.4**  Welfare
      Benefit Plans .
      During
      the Employment Period, the Executive and/or the Executive’s family, as the case
      may be, shall be eligible for participation in and shall receive all benefits
      under welfare benefit plans, practices, policies and programs (“Welfare Plans”)
      provided by the Company (including, without limitation, medical, prescription,
      dental, disability, salary continuance, employee life, group life, accidental
      death and travel accident insurance benefits), but in no event shall such
      Welfare Plans provide the Executive with benefits which are less favorable,
      in
      the aggregate, than the greater of (i) those provided by the Company for
      the Executive under such Welfare Plans as were in effect at any time during
      the
      90-day period immediately preceding the Effective Date, or (ii) those
      provided generally at any time after the Effective Date to other senior
      executives of the Company.




**3.2.5**  Other
      Employee Benefits .
      During
      the Employment Period, the Executive shall be entitled to other employee
      benefits and perquisites in accordance with the most favorable plans, practices,
      programs and policies of the Company, as in effect with respect to the Executive
      at any time during the 90-day period immediately preceding the Effective Date,
      or if more favorable, as in effect generally with respect to other senior
      executives of the Company.




**3.2.6**  Expenses .
      The
      Executive shall be entitled to receive prompt reimbursements for all reasonable
      expenses incurred by the Executive during the Employment Period in accordance
      with the policies, practices and procedures of the Company, as in effect with
      respect to the Executive at any time during the 90-day period immediately
      preceding the Effective Date, or if more favorable, as in effect generally
      with
      respect to other senior executives of the Company. All such expenses shall
      be
      reimbursed no later than the date six (6) months following the Termination
      Date.
      The amount of expenses reimbursed in one year shall not affect the amount
      eligible for reimbursement in any subsequent year.

      and Support Staff .
      During
      the Employment Period, the Executive shall be entitled to an office or offices
      of a size and with furnishings and other appointments, and to exclusive personal
      secretarial and other assistance, as in effect with respect to the Executive
      at
      any time during the 90-day period immediately preceding the Effective Date,
      or
      if more favorable, as provided generally with respect to other senior executives
      of the Company.




**3.2.8**  Paid
      Time Off .
      During
      the Employment Period, the Executive shall be entitled to paid time off in
      accordance with the plans, policies, programs and practices of the Company
      as in
      effect with respect to the Executive at any time during the 90-day period
      immediately preceding the Effective Date, or if more favorable, as provided
      generally with respect to other senior executives of the Company.




6


**3.2.9**  Subsidiaries .
      To the
      extent that immediately prior to the Effective Date, the Executive has been
      on
      the payroll of, and participated in the incentive or employee benefit plans
      of,
      a Subsidiary of the Company, the references to the Company contained in
      Sections 3.2.1 through 3.2.8 and the other sections of this Agreement
      referring to benefits to which the Executive may be entitled shall be read

      OF EMPLOYMENT**




**4.1.** **Disability** **.**




**4.1.1**  During
      the Agreement Term, the Company and Nicor Gas may terminate the Executive’s
      employment upon the Executive’s Permanent Disability (as defined in
      Section 4.1.2) by giving the Executive or his legal representative, as
      applicable, (1) written notice in accordance with Section 11.8 of the
      Company’s or Nicor Gas’, as applicable, intention to terminate the Executive’s
      employment pursuant to this section, and (2) a certification of the
      Executive’s Permanent Disability by a physician selected by the Company or Nicor
      Gas or its insurers and reasonably acceptable to the Executive or the
      Executive’s legal representative. The Executive’s employment shall terminate
      effective on the 30th day (the “Permanent Disability Effective Date”) after the
      Executive’s receipt of such notice unless, before the Permanent Disability
      Effective Date, the Executive shall have resumed the full-time performance
      of
      the Executive’s duties. During the period in which the Executive has a
      Disability, the Company or Nicor Gas, as applicable, may appoint a temporary
      replacement to assume the Executive’s responsibilities.




**4.1.2**  The
      Executive shall be considered to have a “Permanent Disability” during any period
      in which he has a Disability (as defined below); provided, however, that the
      Executive shall not be considered to have “Permanent Disability” until (i) for a
      period of 180 consecutive days, the Executive, as a result of a Disability,
      is
      incapable, after reasonable accommodation, of performing his duties under this
      Agreement on a full-time basis; (ii) such Disability is reasonably expected
      to
      continue for at least another 90 days; and (iii) at the Executive’s
      Termination Date, he is eligible for income replacement benefits under the
      Company’s or Nicor Gas’ long-term disability plan. The Executive shall be
      considered to have a “Disability” during any period in which he has a physical
      or mental disability which renders him incapable, after reasonable
      accommodation, of performing his duties under this Agreement.




**4.2.** **Death** .
      The
      Executive’s employment shall terminate automatically upon the Executive’s death
      during the Agreement Term.




**4.3.** **Cause** .
      The
      Company or Nicor Gas, as applicable, may terminate the Executive’s employment
      during the Employment Period for Cause. For purposes of this Agreement, “Cause”
means:




**4.3.1**  the
      Executive’s willful commission of acts or omissions which have, have had, or are
      likely to have a material adverse effect on the business, operations, financial
      condition or reputation of the Company or Nicor Gas;




7


**4.3.2**  the
      Executive’s conviction (including a plea of guilty or nolo contendere) of a
      felony or any crime of fraud, theft, dishonesty or moral turpitude;
      or




**4.3.3**  the
      Executive’s material violation of any statutory or common law duty of loyalty to
      the Company or Nicor Gas.




For
      purposes of this Agreement, no act, or failure to act, on the part of the
      Executive shall be considered “willful” unless it is done, or omitted to be
      done, by the Executive in bad faith or without reasonable belief that the
      Executive’s action or omission was in the best interests of the Company or Nicor
      Gas. Any act, or failure to act, pursuant to direction provided by the person
      to
      whom the Executive reports, or provided by a resolution duly adopted by the
      Board, or pursuant to advice of counsel for the Company or Nicor Gas, shall
      be
      conclusively presumed to be done, or omitted to be done, by the Executive in
      good faith and in the best interests of the Company or Nicor Gas.




**4.4.** **Good
      Reason** .
      During
      the Employment Period, the Executive’s employment may be terminated by the
      Executive for Good Reason. For purposes of this Agreement, “Good Reason” means:




**4.4.1**  a
      material diminution in the Executive’s base compensation;




**4.4.2**  a
      material diminution in the authority, duties or responsibilities of the
      Executive;




**4.4.3**  a
      material change, of not less than 25 miles, in the geographic location at which
      the Executive must provide services; or




**4.4.4**  any
      other
      action or inaction that constitutes a material breach by the Company of this
      Agreement;




provided,
      however, that the above conditions, as applicable, shall not constitute Good
      Reason: (i) unless the Executive gives the Company or Nicor Gas, as applicable,
      written notice of such condition and the Company or Nicor Gas, as applicable,
      fails to remedy the condition within 30 days of such notice; (ii) if the initial
      existence of the condition is more than 90 days before the Executive gives
      the
      Company or Nicor Gas such notice; or (iii) if the Executive has consented in
      writing to such condition in a document that makes specific reference to this
      Section 4.4.




**4.5.** **Without
      Cause During a Potential Change in Control** .
      If the
      Executive’s employment is terminated by the Company and Nicor Gas, as
      applicable, without Cause during a Potential Change in Control, and such date
      of
      termination occurs not more than 180 days prior to the occurrence of a
      Change in Control and the Executive establishes by reasonable evidence that
      such
      termination of employment was materially connected with and in anticipation
      of
      the Change in Control, then the Executive shall be entitled to receive the
      benefits that would have been provided under Section 5.1, determined as
      though:




8


**4.5.1**  the
      Executive were rehired by the Company and Nicor Gas, as applicable, immediately
      prior to the Change in Control at the salary rate equal to the Executive’s
      highest salary rate during the one-year period prior to the date of the Change
      in Control, and with other Company and Nicor Gas compensation and benefit
      arrangements comparable to those provided to comparable executives of the
      Company and Nicor Gas;




**4.5.2**  the
      Executive’s employment were terminated by the Company and Nicor Gas without
      Cause immediately after the Change in Control; and




**4.5.3**  this
      Agreement were in full force and effect at the time of the Change in Control,
      and at the time of the Executive’s deemed termination of
      employment.




**4.6.** **Right
      of Resignation and Termination** .
      This
      Agreement does not constitute a guarantee of continued employment at any time,
      but instead provides for certain rights and benefits for the Executive during
      his employment following the occurrence of a Change in Control, and in the
      event
      his employment with the Company and Nicor Gas, as applicable, terminates under
      the circumstances described herein. The Company and Nicor Gas, as applicable,
      may terminate the employment of the Executive at any time for any reason,
      without breach of this Agreement, subject to its obligations set forth in
      Article V and elsewhere in this Agreement. The Executive may resign from the
      Company and Nicor Gas, as applicable, for Good Reason, or for any other reason,
      without breach of this Agreement, subject to the Executive’s obligations set
      forth in this Agreement; provided that, in the event of a resignation without
      Good Reason, the Executive shall provide at least four weeks advance notice
      of
      such resignation to the Company and Nicor Gas, as applicable.




**ARTICLE
      V**


**OBLIGATIONS
      OF THE COMPANY UPON TERMINATION**




**5.1.** **If
      by the Executive for Good Reason or by the Company and Nicor Gas, as Applicable,
      Other Than for Cause or Permanent Disability** .
      If,
      during the Employment Period, the Company and Nicor Gas, as applicable, shall
      terminate the Executive’s employment other than for Cause or Permanent
      Disability, or if the Executive shall terminate employment for Good Reason,
      the
      Company’s and Nicor Gas’ obligations to the Executive shall be as set forth in
      this Section 5.1. As a precondition to fulfilling such obligations, the
      Company shall require the Executive to execute and deliver within 60 days
      following his Termination Date a release prepared by the Company and providing
      for the Executive’s release of any and all claims against the Company and its
      Subsidiaries (and those acting on behalf of them) that may have arisen on or
      before the date of the release, which release shall contain such other
      reasonable and customary terms as are specified by the Company. Notwithstanding
      any provisions to the contrary, no payments shall be made or other benefits
      arise pursuant to this Section 5.1 unless and until such binding release is
      effective. If such release is not delivered by the Executive within 60 days
      following the Executive’s Termination Date, all rights of the Executive with
      respect to this Agreement and any benefits hereunder shall be forfeited.




**5.1.1**  The
      Company shall, within five business days of the Payment Date, pay the Executive
      a cash payment equal to the sum of the following amounts:




9


**5.1.1.1**  to
      the
      extent not previously paid, the Annual Base Salary and any accrued paid time
      off
      through the Termination Date;




**5.1.1.2**  an
      amount
      equal to the product of (i) the Annual Incentive (as defined in
      Section 3.2.2) at target for any Performance Period in which the
      Termination Date occurs multiplied by (ii) a fraction, the numerator of
      which is the number of days the Executive was actually employed by the Company
      during such Performance Period, and the denominator of which is the number
      of days in the Performance Period; or, if greater, the amount of any Annual
      Incentive otherwise payable to the Executive with respect to a Performance
      Period in which the Termination Date occurs, which payment shall be in full
      settlement of Annual Incentive amounts due with respect to any such Performance
      Period;




**5.1.1.3**  an
      amount
      equal to the product of (A) three (3) multiplied by (B) the sum of
      (i) the Executive’s Annual Base Salary, and (ii) the Severance
      Incentive; and




**5.1.1.4**  an
      amount
      equal to the sum of (A) the balance of the Executive’s accounts forfeited under
      the Company’s Savings Investment Plan, or any successor plan, if applicable
      (“SIP”) and the Nicor Gas Supplementary Savings Plan (“SSIP”) as a result of
      termination of employment, and (B) the sum of (i) the aggregate maximum matching
      contributions which the Company would have made on behalf of the Executive
      to
      the SIP and the SSIP for the Severance Period, calculated as if the amount
      payable under subsection 5.1.1.3 of this Agreement had been earned equally
      over
      the Severance Period and the Executive had made the maximum allowable voluntary
      contributions to the SIP and SSIP, and (ii) the aggregate additional “retirement
      growth” contributions, if any, which the Company would have made on behalf of
      the Executive for the Severance Period to the SIP and SSIP if the amount payable
      under subsection 5.1.1.3 of this Agreement had been earned equally over the
      Severance Period. For purposes of calculating the amount that would be
      contributed to the SIP and SSIP for the Severance Period under this Section
      5.1.1.4(B), the limits contained in the plan documents and Internal Revenue
      Code
      Sections 415, 402(g) and 401(a)(17), for the year of termination shall
      apply.




**5.1.2**  For
      purposes of each of the Executive’s stock options granted under the Company’s
      Long Term Incentive Plan (the “LTIP”), any successor plan, or otherwise, that is
      or becomes exercisable on the Termination Date, the Executive’s Separation from
      Service shall be disregarded, and each such option shall continue to be
      exercisable as though the Executive’s employment had continued through the last
      day on which such option would be exercisable in the absence of such Separation
      from Service (such earlier date being referred to herein as the “Applicable
      Expiration Date”). This Section 5.1.2 shall be applicable notwithstanding
      any term of any plan, arrangement, or agreement providing for early expiration
      of the option because of the Executive’s Separation from Service, except for an
      amendment adopted in accordance with Section 11.7 of this Agreement and
      that by its specific terms amends this Agreement.




10


**5.1.3**  On
      the
      Termination Date (i) the Executive shall become fully vested in, and may
      thereupon and until the Applicable Expiration Date of such stock incentive
      awards exercise in whole or in part, any and all stock incentive awards granted
      to the Executive under the LTIP, any successor plan or otherwise which have
      not
      become exercisable as of the Termination Date; (ii) all performance units
      previously awarded to the Executive shall become vested, and a prorated
      calculation of the target value of all such units shall be done as of the
      Termination Date and full payment of such prorated target value shall be made
      by
      the Company within 30 days after the Termination Date; and (iii) the
      Executive shall become fully vested at the prorated target level in any other
      cash incentive awards granted for the performance period in which the
      Termination Date occurs under the LTIP, a successor plan or otherwise which
      have
      not, as of the Termination Date, become fully vested.




**5.1.4**  All
      forfeiture conditions that as of the Termination Date are applicable to any
      deferred stock unit, deferred dividends, restricted stock or restricted share
      units awarded to the Executive by the Company pursuant to the LTIP, a successor
      plan or otherwise shall lapse immediately (to the extent such awards are
      outstanding immediately prior to the Termination Date). Notwithstanding the
      foregoing, to the extent such awards are subject to performance criteria, a
      prorated calculation of the target value of such awards shall be performed
      and
      forfeiture conditions shall lapse only with respect to the portion of such
      awards attributable to such prorated value.




**5.1.5**  During
      the Severance Period (or until such later date as any Welfare Plan of the
      Company may specify), the Company shall continue to provide to the Executive
      and
      the Executive’s family welfare benefits (including, without limitation, medical,
      prescription, dental, disability, individual life and group life insurance
      benefits) which are at least as favorable as those provided under the most
      favorable Welfare Plans of the Company applicable (i) with respect to the
      Executive and his family during the 90-day period immediately preceding the
      Termination Date, or (ii) with respect to other senior executives and their
      families during the Severance Period. In determining benefits under such Welfare
      Plans, the Executive’s annual compensation attributable to base salary and
      incentives for any plan year or calendar year, as applicable, shall be deemed
      to
      be not less than the Executive’s Annual Base Salary and Target Annual Incentive.
      The cost of the welfare benefits provided under this Section 5.1.5 shall
      not exceed the cost of such benefits to the Executive immediately before the
      Termination Date or, if less, the Effective Date. All such benefit payments
      shall be made no later than December 31 of the year following the year in which
      the expense was incurred. The amount of benefits provided in one year shall
      not
      affect the amounts provided in any subsequent year. Such benefits shall not
      be
      subject to liquidation or exchange for another benefit. Notwithstanding the
      foregoing, if the Executive obtains comparable coverage under any Welfare Plans
      sponsored by another employer, then the amount of coverage required to be
      provided by the Company hereunder shall be reduced by the amount of coverage
      provided by such other employer’s Welfare Plans. The Executive’s rights under
      this Section shall be in addition to and not in lieu of any
      post-termination continuation coverage or conversion rights the Executive may
      have pursuant to applicable law, including, without limitation, continuation
      coverage required by Section  4980B of the Code. For purposes of
      determining eligibility for (but not the time of commencement of) retiree
      benefits under any Welfare Plans of the Company, the Executive shall be
      considered (i) to have remained employed until the last day of the
      Severance Period and to have retired on the last




11
 
 day
        of
        such period, and (ii) to have attained the age the Executive would have
        attained on the last day of the Severance Period.




**5.1.6**  If
      the
      Executive participates in the Company’s nonqualified supplemental executive
      retirement plan (“SERP”), the amount payable under subsection 5.1.1.3 of
      this Agreement shall be taken into account for purposes of determining the
      amount of benefits to which the Executive is entitled under the SERP; provided
      that such amount shall be taken into account as though it was earned equally
      over the Severance Period, and further provided that the Executive shall be
      deemed to have attained the age he or she would have attained as of the last
      day
      of the Severance Period, and completed the number of years of service he or
      she
      would have completed as of the last day of the Severance Period. The Severance
      Period shall be taken into account for purposes of determining the amount of
      and
      eligibility to begin to receive benefits under the SERP.




**5.1.7**  If
      the
      Executive participates in the Company’s nonqualified Supplemental Senior Officer
      Retirement Plan (“SSORP”), on the Termination Date (i) the Executive shall
      become fully vested in all contributions (and in any earnings applied to such
      contributions) made by the Company on behalf of the Executive under the SSORP
      or
      any successor plan, if applicable, and (ii) the Company shall immediately make
      an additional contribution to the SSORP of an amount equal to the product of
      (x)
      the Annual Deferral Percentage (as defined in the SSORP) used for the most
      recently completed SSORP Plan Year, times (y) the amount payable under
      subsection 5.1.1.3 of this Agreement.




**5.1.8**  During
      the Severance Period, the Company shall, at its sole expense, as incurred,
      pay
      on behalf of Executive all fees and costs charged by a nationally recognized
      outplacement firm selected by the Company (subject to approval by the Executive,
      which shall not be withheld unreasonably) to provide outplacement services.
      The
      amount of expenses incurred in one year shall not affect the amounts paid in
      any
      subsequent year.




**5.2.** **If
      by the Company and Nicor Gas for Cause** .
      If the
      Company and Nicor Gas, as applicable, terminates the Executive’s employment for
      Cause during the Employment Period, this Agreement shall terminate without
      further obligation by the Company and Nicor Gas, as applicable, to the
      Executive, other than the obligation immediately to pay the Executive in cash
      the Executive’s Annual Base Salary through the Termination Date, plus any
      accrued paid time off, in each case to the extent not previously
      paid.




**5.3.** **If
      by the Executive Other Than for Good Reason** .
      If the
      Executive terminates employment during the Employment Period other than for
      Good
      Reason (including, but not by way of limitation, voluntary retirement), and
      other than for Disability or death, this Agreement shall terminate without
      further obligation by the Executive or by the Company, other than the obligation
      of the Company immediately to pay the Executive in cash the Executive’s Annual
      Base Salary through the Termination Date, plus any accrued paid time off, in
      each case to the extent not previously paid.




**5.4.** **If
      by the Company and Nicor Gas, as applicable, for Permanent
      Disability** .
      If the
      Company or Nicor Gas, as applicable, terminates the Executive’s employment by
      reason of




12
 
 the
        Executive’s Permanent Disability during the Employment Period, this Agreement
        shall terminate without further obligation to the Executive, other
        than:




**5.4.1**  the
      Company’s obligation immediately to pay the Executive in cash all amounts
      specified in Sections 5.1.1.1, and 5.1.1.2, in each case, to the extent unpaid
      as of the Termination Date (such amounts collectively, the “Accrued
      Obligations”), and




**5.4.2**  the
      Executive’s right after the Permanent Disability Effective Date to receive
      disability and other benefits at least equal to the greater of (i) those
      provided under the most favorable disability Plans applicable to disabled senior
      executives of the Company in effect immediately before the Termination Date,
      or
      (ii) those provided under the most favorable disability Plans of the
      Company in effect at any time during the 90-day period immediately before the
      Effective Date.




**5.5.** **If
      upon Death** .
      If the
      Executive’s employment is terminated by reason of the Executive’s death during
      the Employment Period, this Agreement shall terminate without further obligation
      to the Executive’s legal representatives under this Agreement, other than the
      obligation immediately to pay the Executive’s estate or beneficiary in cash all
      Accrued Obligations. Notwithstanding anything in this Agreement to the contrary,
      the Executive’s family shall be entitled to receive benefits at least equal to
      the most favorable benefits provided under Plans of the Company to the surviving
      families of senior executives of the Company, but in no event shall such Plans
      provide benefits which in each case are less favorable, in the aggregate, than
      the most favorable of those provided by the Company to the Executive under
      such
      Plans in effect at any time during the 90-day period immediately before the
      Effective Date.




**ARTICLE
      VI**


**CERTAIN
      ADDITIONAL PAYMENTS BY THE COMPANY**




**6.1.** **Gross-up
      for Certain Taxes** .




**6.1.1**  If
      it is
      determined by the Company’s independent auditors that any benefit received or
      deemed received by the Executive from the Company pursuant to this Agreement
      or
      otherwise, whether or not in connection with a Change in Control (such monetary
      or other benefits collectively, the “Potential Parachute Payments”) is or will
      become subject to any excise tax under Section 4999 of the Code or any
      similar tax payable under any United States federal, state, local or other
      law
      (such excise tax and all such similar taxes collectively, “Excise Taxes”), then
      the Company shall, subject to Sections 6.6 and 6.7, within five business
      days after such determination, pay the Executive an amount (the “Gross-up
      Payment”) equal to the product of:




(a)  the
      amount of such Excise Taxes multiplied by




(b)  the
      Gross-up Multiple (as defined in Section 6.4). The Gross-up Payment is
      intended to compensate the Executive for all Excise Taxes payable by the
      Executive with respect to the Potential Parachute Payments and any federal,
      state, local or other income or other taxes or Excise Taxes payable by the
      Executive with respect to the Gross-up Payment.




13


**6.1.2**  The
      determination of the Company’s independent auditors described in
      Section 6.1.1, including the detailed calculations of the amounts of the
      Potential Parachute Payments, Excise Taxes and Gross-up Payment and the
      assumptions relating thereto, shall be set forth in a written certificate of
      such auditors (the “Company Certificate”) delivered to the Executive. The
      Executive or the Company may at any time request the preparation and delivery
      to
      the Executive of a Company Certificate. The Company shall cause the Company
      Certificate to be delivered to the Executive as soon as reasonably possible
      after such request.




**6.1.3**  All
      determinations by the Company’s auditors under this Section 6.1 shall be made
      using reasonable good faith interpretations of the Code, the regulations and
      other guidance issued thereunder.




**6.2.** **Determination
      by the Executive** .




**6.2.1**  If
      (i) the Company shall fail to deliver a Company Certificate to the
      Executive within 30 days after its receipt of his written request therefor,
      or (ii) at any time after the Executive’s receipt of a Company Certificate,
      the Executive disputes either (x) the amount of the Gross-up Payment set
      forth therein, or (y) the determination set forth therein to the effect
      that no Gross-up Payment is due (whether by reason of Section 6.7 or
      otherwise), then the Executive may elect to require the Company to pay a
      Gross-up Payment in the amount determined by the Executive as set forth in
      an
      Executive Counsel Opinion (as defined in Section 6.5). Any such demand by
      the Executive shall be made by delivery to the Company of a written notice
      which
      specifies the Gross-up Payment determined by the Executive (together with the
      detailed calculations of the amounts of Potential Parachute Payments, Excise
      Taxes and Gross-up Payment and the assumptions relating thereto) and an
      Executive Counsel Opinion regarding such Gross-up Payment (such written notice
      and opinion collectively, the “Executive’s Determination”). Within 30 days
      after delivery of an Executive’s Determination to the Company, the Company shall
      either (i) pay the Executive the Gross-up Payment set forth in Executive’s
      Determination (less the portion thereof, if any, previously paid to Executive
      by
      the Company) or (ii) deliver to the Executive a Company Certificate and a
      Company Counsel Opinion (as defined in Section 6.5), and pay the Executive
      the Gross-up Payment specified in such Company Certificate. If for any reason
      the Company fails to comply with the preceding sentence, the Gross-up Payment
      specified in the Executive’s Determination shall be controlling for all
      purposes.




**6.2.2**  If
      the
      Executive does not request a Company Certificate, and the Company does not
      deliver a Company Certificate to the Executive, then (i) the Company shall,
      for purposes of Section 6.7, be deemed to have determined that no Gross-up
      Payment is due, and (ii) the Executive shall not pay any Excise Taxes in
      respect of Potential Parachute Payments, except in accordance with
      Sections 6.6.1 or 6.6.4.




**6.3.** **Additional
      Gross-up Amounts** .
      If for
      any reason it is later determined (whether pursuant to the subsequently-enacted
      provisions of the Code, final regulations or published rulings of the IRS,
      a
      final judgment of a court of competent jurisdiction, a determination of the
      Company’s independent auditors set forth in a Company Certificate or, subject to
      the last two sentences of Section 6.2.1, an Executive’s Determination) that
      the amount of Excise Taxes




14
 
 payable
        by the Executive is greater than the amount determined by the Company or
        the
        Executive pursuant to Section 6.1 or 6.2, as applicable, then the Company
        shall, subject to Sections 6.6 and 6.7, pay the Executive an amount (which
        shall also be deemed a Gross-up Payment) equal to the product
        of:




(a)  the
      sum
      of (1) such additional Excise Taxes and (2) any interest, fines,
      penalties, expenses or other costs incurred by the Executive as a result of
      having taken a position in accordance with determination made pursuant to
      Section 6.1 or 6.2, as applicable,




multiplied
      by




(b)  the
      Gross-up Multiple.




**6.4.** **Gross-up
      Multiple** .
      The
      Gross-up Multiple shall equal a fraction, the numerator of which is
      one (1.0), and the denominator of which is one (1.0) minus the lesser
      of (i) the sum, expressed as a decimal fraction, of the effective marginal
      tax rates of all federal, state, local and other income and other taxes and
      any
      Excise Taxes applicable to the Gross-up Payment; or (ii) 0.80, it being
      intended that the Gross-up Multiple shall in no event exceed five (5.0).
      (If different rates of tax are applicable to various portions of a Gross-up
      Payment, the weighted average of such rates shall be used.)




**6.5.** **Opinion
      of Counsel** .
      “Executive Counsel Opinion” means an opinion of nationally-recognized executive
      compensation counsel to the effect (i) that the amount of the Gross-up
      Payment determined by the Executive pursuant to Section 6.2 is the amount
      that a court of competent jurisdiction, based on a final judgment not subject
      to
      further appeal, is most likely to decide to have been calculated in accordance
      with this Article and applicable law and (ii) if the Company has previously
      delivered a Company Certificate to the Executive, that there is no reasonable
      basis or no substantial authority for the calculation of the Gross-up Payment
      set forth in the Company Certificate. “Company Counsel Opinion” means an opinion
      of nationally-recognized executive compensation counsel to the effect that
      (i) the amount of the Gross-up Payment set forth in the Company Certificate
      is the amount that a court of competent jurisdiction, based on a final judgment
      not subject to further appeal, is most likely to decide to have been calculated
      in accordance with this Article and applicable law and (ii) for purposes of
      Section 6662 of the Code, the Executive has substantial authority to report
      on his federal income tax return the amount of Excise Taxes set forth in the
      Company Certificate.




**6.6.** **Amount
      Increased or Contested** .




**6.6.1**  The
      Executive shall notify the Company in writing (an “Executive’s Notice”) of any
      claim by the IRS or other taxing authority (an “IRS Claim”) that, if successful,
      would require the payment by the Executive of Excise Taxes in respect of
      Potential Parachute Payments in an amount in excess of the amount of such Excise
      Taxes determined in accordance with Section 6.1 or 6.2, as applicable. Such
      Executive’s Notice shall include the nature and amount of such IRS Claim, the
      date on which such IRS Claim is due to be paid (the “IRS Claim Deadline”), and a
      copy of all notices and other documents or correspondence received by
      the




15
 
 Executive
        in respect of such IRS Claim. The Executive shall give the Executive’s Notice as
        soon as practicable, but no later than the earlier of (i) 10 business
        days after the Executive first obtains actual knowledge of such IRS Claim
        or
        (ii) five business days before the IRS Claim Deadline; provided, however,
        that the Executive’s failure to give such notice shall affect the Company’s
        obligations under this Article only to the extent that the Company is actually
        prejudiced by such failure. If at least one business day before the IRS Claim
        Deadline the Company shall:




**6.6.1.1**  deliver
      to the Executive a Company Certificate to the effect that the IRS Claim has
      been
      reviewed by the Company’s independent auditors and, notwithstanding the IRS
      Claim, the amount of Excise Taxes, interest and penalties payable by the
      Executive is either zero or an amount less than the amount specified in the
      IRS
      Claim,




**6.6.1.2**  pay
      to
      the Executive an amount (which shall also be deemed a Gross-up Payment) equal
      to
      the positive difference between (x) the product of the amount of Excise
      Taxes, interest and penalties specified in the Company Certificate, if any,
      multiplied by the Gross-up Multiple, and (y) the portion of such product,
      if any, previously paid to the Executive by the Company, and




**6.6.1.3**  direct
      the Executive pursuant to Section 6.6.4 to contest the balance of the IRS
      Claim, then the Executive shall pay only the amount, if any, of Excise Taxes,
      interest and penalties specified in the Company Certificate. In no event shall
      the Executive pay an IRS Claim earlier than 30 days after having given an
      Executive’s Notice to the Company (or, if sooner, the IRS Claim
      Deadline).




**6.6.2**  At
      any
      time after the payment by the Executive of any amount of Excise Taxes or related
      interest or penalties in respect of Potential Parachute Payments (whether or
      not
      such amount was based upon a Company Certificate or an Executive’s
      Determination), the Company may in its discretion require the Executive to
      pursue a claim for a refund (“Refund Claim”) of all or any portion of such
      Excise Taxes, interest or penalties as the Company may specify by written notice
      to the Executive.




**6.6.3**  If
      the
      Company notifies the Executive in writing that the Company desires the Executive
      to contest an IRS Claim or to pursue a Refund Claim, the Executive
      shall:




**6.6.3.1**  give
      the
      Company all information that it reasonably requests in writing from time to
      time
      relating to such IRS Claim or Refund Claim, as applicable,




**6.6.3.2**  take
      such
      action in connection with such IRS Claim or Refund Claim (as applicable) as
      the
      Company reasonably requests in writing from time to time, including accepting
      legal representation with respect thereto by an attorney selected by the
      Company, subject to the approval of the Executive (which approval shall not
      be
      unreasonably withheld or delayed),




16


**6.6.3.3**  cooperate
      with the Company in good faith to contest such IRS Claim or pursue such Refund
      Claim, as applicable,




**6.6.3.4**  permit
      the Company to participate in any proceedings relating to such IRS Claim or
      Refund Claim, as applicable, and




**6.6.3.5**  contest
      such IRS Claim or prosecute such Refund Claim (as applicable) to a determination
      before any administrative tribunal, in a court of initial jurisdiction and
      in
      one or more appellate courts, as the Company may from time to time determine
      in
      its discretion.




The
      Company shall control all proceedings in connection with such IRS Claim or
      Refund Claim (as applicable) and in its discretion may cause the Executive
      to
      pursue or forego any and all administrative appeals, proceedings, hearings
      and
      conferences with the IRS or other taxing authority in respect of such IRS Claim
      or Refund Claim (as applicable); provided that (i) any extension of the
      statute of limitations relating to payment of taxes for the taxable year of
      the
      Executive relating to the IRS Claim is limited solely to such IRS Claim,
      (ii) the Company’s control of the IRS Claim or Refund Claim (as applicable)
      shall be limited to issues with respect to which a Gross-up Payment would be
      payable, and (iii) the Executive shall be entitled to settle or contest, as
      the case may be, any other issue raised by the IRS or other taxing
      authority.




**6.6.4**  The
      Company may at any time in its discretion direct the Executive to
      (i) contest the IRS Claim in any lawful manner or (ii) pay the amount
      specified in an IRS Claim and pursue a Refund Claim; provided, however, that
      if
      the Company directs the Executive to pay an IRS Claim and pursue a Refund Claim,
      the Company shall advance the amount of such payment to the Executive on an
      interest-free basis and shall indemnify the Executive, on an after-tax basis,
      for any income or other applicable taxes or Excise Tax, and any related interest
      or penalties imposed with respect to such advance.




**6.6.5**  The
      Company shall pay directly all legal, accounting and other costs and expenses
      (including additional interest and penalties) incurred by the Company or the
      Executive in connection with any IRS Claim or Refund Claim, as applicable,
      and
      shall indemnify the Executive, on an after-tax basis, for any income or other
      applicable taxes, Excise Tax and related interest and penalties imposed on
      the
      Executive as a result of such payment of costs and expenses.




**6.7.** **Refunds** **.** If,
      after the receipt by the Executive of any payment or advance of Excise Taxes
      advanced by the Company pursuant to Section 6.6, the Executive receives any
      refund with respect to such claim, the Executive shall (subject to the Company’s
      complying with the requirements of Section 6.6) promptly pay the Company
      the amount of such refund (together with any interest paid or credited thereon
      after taxes applicable thereto). If, after the receipt by the Executive of
      an
      amount advanced by the Company pursuant to Section 6.6, a determination is
      made that the Executive shall not be entitled to any refund with respect to
      such
      claim and the Company does not notify the Executive in writing of its intent
      to
      contest such determination within 30 days after the Company receives
      written notice of such determination, then such advance shall be forgiven and
      shall not be required to be repaid and the amount of such advance




17
 
 shall
        offset, to the extent thereof, the amount of Gross-up Payment required to
        be
        paid. Any contest of a denial of refund shall be controlled by
        Section 6.6.




**6.8.** **Payments** .
      All
      amounts payable to Executive under Section 6.1, 6.3 or 6.6 shall be paid as
      soon
      as practicable after a Change in Control or other event giving rise to any
      payment of the Excise Tax by the Executive, but no later than the December
      31 of
      the year next following the year in which the Executive, or the Company on
      behalf of the Executive, remits the Excise Tax.




**ARTICLE
      VII**


**EXPENSES
      AND INTEREST**




**7.1.** **Legal
      Fees and Other Expenses** .




**7.1.1**  During
      the Employment Period and for a period of ten (10) years following the
      Termination Date, if the Executive incurs legal fees or other expenses in an
      effort to secure, preserve, establish entitlement to, or obtain benefits under
      this Agreement (including, without limitation, the fees and other expenses
      of
      the Executive’s legal counsel in connection with the delivery of the Executive
      Counsel opinion referred to in Section 6.5), then the Company shall, regardless
      of the outcome of such effort, promptly reimburse the Executive on a current
      basis for such fees and expenses following the Executive’s written submission of
      a request for reimbursement together with evidence that such fees and expenses
      were incurred. All such expenses shall be reimbursed by December 31 of the
      year
      following the year in which the expense was incurred. The amount of expenses
      reimbursed in one year shall not affect the amount eligible for reimbursement
      in
      any subsequent year.




**7.1.2**  If
      the
      Executive does not prevail (after exhaustion of all available judicial remedies)
      in respect of a claim by the Executive or by the Company hereunder, and the
      Company establishes before a court of competent jurisdiction, by clear and
      convincing evidence, that the Executive had no reasonable basis for his claim
      hereunder, or for his response to the Company’s claim hereunder, and acted in
      bad faith, no further reimbursement for legal fees and expenses shall be due
      to
      the Executive in respect of such claim and the Executive shall refund any
      amounts previously reimbursed hereunder with respect to such claim.




**7.2.** **Interest** **.** Except
      for any required delay under Section 11.16, if the Company and Nicor Gas, as
      applicable, does not pay any amount due to the Executive under this Agreement
      within three days after such amount became due and owing, interest shall accrue
      on such amount from the date it became due and owing until the date of payment
      at an annual rate equal to 200 basis points above the base commercial lending
      rate published in The Wall Street Journal in effect from time to time during
      the
      period of such nonpayment.







**ARTICLE
      VIII**


**NO
      SET-OFF OR MITIGATION**




**8.1.** **No
      Set-off by Company** .
      The
      Executive’s right to receive when due the payments and other benefits provided
      for under this Agreement is absolute, unconditional and




18
 
 subject
        to no set-off, counterclaim or legal or equitable defense. Any claim which
        the
        Company may have against the Executive, whether for a breach of this Agreement
        or otherwise, shall be brought in a separate action or proceeding and not
        as
        part of any action or proceeding brought by the Executive to enforce any
        rights
        against the Company under this Agreement.




**8.2.** **No
      Mitigation** .
      The
      Executive shall not have any duty to mitigate the amounts payable by the Company
      and Nicor Gas, as applicable, under this Agreement by seeking new employment
      following termination. Except as specifically otherwise provided in this
      Agreement, all amounts payable pursuant to this Agreement shall be paid without
      reduction regardless of any amounts of salary, compensation or other amounts
      which may be paid or payable to the Executive as the result of the Executive’s
      employment by another employer.




**ARTICLE
      IX**


**NON-EXCLUSIVITY
      OF RIGHTS**




**9.1.** **Waiver
      of Other Severance Rights** .
      Except
      as may be otherwise specifically provided in an amendment of this
      Section 9.1 adopted in accordance with Section 11.7 of this Agreement,
      the Executive’s rights under Section 5.1 of this Agreement shall be in lieu
      of any benefits that may be otherwise payable to or on behalf of the Executive
      pursuant to the terms of any severance pay arrangement of the Company or any Subsidiary or any
      other, similar arrangement of the Company or any Subsidiary providing benefits
      upon involuntary termination of employment and shall also be in lieu of any
      benefits under the Nicor Inc. Executive/Key Employee Severance Benefits Program
      (notwithstanding any provision of that program to the contrary); provided,
      however, that this Section 9.1 shall not affect the Executive’s rights to
      receive any benefits with respect to a termination of employment that occurs
      outside of the Employment Period. To the extent Executive receives severance
      or
      similar payments and/or benefits under any other plan, program, agreement,
      policy, practice, or the like of Nicor Gas, the Company or any Subsidiary,
      or
      under the WARN Act or similar state law, the payments and benefits due to
      Executive under this Agreement will be correspondingly reduced on a
      dollar-for-dollar basis (or vice-versa).




**9.2.** **Other
      Rights** .
      Except
      as provided in Section 9.1, this Agreement shall not prevent or limit the
      Executive’s continuing or future participation in any benefit, bonus, incentive
      or other plans provided by the Company or any Subsidiary and for which the
      Executive may qualify, nor shall this Agreement limit or otherwise affect such
      rights as the Executive may have under any other agreements with the Company
      or
      any Subsidiary. Amounts which are vested benefits or which the Executive is
      otherwise entitled to receive under any plan of the Company or any Subsidiary
      and any other payment or benefit required by law at or after the Termination
      Date shall be payable in accordance with such Plan or applicable law except
      as
      expressly modified by this Agreement.




**ARTICLE
      X**


**CONFIDENTIALITY**




**10.1.** **Confidentiality** .
      The
      Executive acknowledges that it is the policy of the Company and its Subsidiaries
      to maintain as secret and confidential all valuable and unique




19
 
 information
        and techniques acquired, developed or used by the Company and its Subsidiaries
        relating to their business, operations, employees and customers, which gives
        the
        Company and its Subsidiaries a competitive advantage in the transmission,
        distribution, marketing, or sale of natural gas or in the energy services
        industry and other businesses in which the Company and its Subsidiaries are
        engaged (“Confidential Information”). The Executive recognizes that all such
        Confidential Information is the sole and exclusive property of the Company
        and
        its Subsidiaries, and that disclosure of Confidential Information would cause
        damage to the Company and its Subsidiaries. The Executive agrees that, except
        as
        required by the duties of his employment with the Company or its Subsidiaries
        and except in connection with enforcing the Executive’s rights under this
        Agreement or if compelled by a court or governmental agency, he will not,
        without the consent of the Company, disseminate or otherwise disclose any
        Confidential Information obtained during his employment with the Company
        or its
        Subsidiaries until such time as such information has been disclosed publicly
        by
        the Company or one of its Subsidiaries, or with its consent, or is otherwise
        a
        matter of public knowledge (unless the Executive has reason to know that
        such
        information became a matter of public knowledge through an unauthorized
        disclosure).




**10.2.** **Remedy** .
      The
      Executive and the Company specifically agree that, in the event that the
      Executive shall breach his obligations under this Article X, the Company
      and its Subsidiaries will suffer irreparable injury and shall be entitled to
      injunctive relief therefor, and shall not be precluded from pursuing any and
      all
      remedies it may have at law or in equity for breach of such obligations;
      provided, however, that such breach shall not in any manner or degree whatsoever
      limit, reduce or otherwise affect the obligations of the Company or Nicor Gas,
      as applicable, under this Agreement, and in no event shall an asserted breach
      of
      the Executive’s obligations under this Article X constitute a basis for
      deferring or withholding any amounts otherwise payable to the Executive under
      this Agreement.




**ARTICLE
      XI**


**MISCELLANEOUS**




**11.1.** **No
      Assignability** .
      This
      Agreement is personal to the Executive and without the prior written consent
      of
      the Company shall not be assignable by the Executive otherwise than by will
      or
      the laws of descent and distribution. This Agreement shall inure to the benefit
      of and be enforceable by the Executive’s legal representatives.




**11.2.** **Successors** .
      Before
      or upon the consummation of any Change in Control, the Company shall obtain
      from
      each individual, group or entity, if any, that becomes a successor of the
      Company by reason of the Change in Control, the unconditional written agreement
      of such individual, group or entity to assume this Agreement and to perform
      all
      of the obligations of the Company hereunder.




**11.3.** **Payments
      to Beneficiary** .
      If the
      Executive dies before receiving amounts to which the Executive is entitled
      under
      this Agreement, such amounts shall be paid in a lump sum to the beneficiary
      designated in writing by the Executive, or if none is so designated, to the
      Executive’s estate.




20


**11.4.** **Nonalienation
      of Benefits** .
      Benefits payable under this Agreement shall not be subject in any manner to
      anticipation, alienation, sale, transfer, assignment, pledge, encumbrance,
      charge, garnishment, execution or levy of any kind, either voluntary or
      involuntary, before actually being received by the Executive, and any such
      attempt to dispose of any right to benefits payable under this Agreement shall
      be void.




**11.5.** **Severability** **.** If any
      one or more articles, sections or other portions of this Agreement are declared
      by any court or governmental authority to be unlawful or invalid, such
      unlawfulness or invalidity shall not serve to invalidate any article, section
      or
      other portion not so declared to be unlawful or invalid. Any article, section
      or
      other portion so declared to be unlawful or invalid shall be construed so as
      to
      effectuate the terms of such article, section or other portion to the fullest
      extent possible while remaining lawful and valid.




**11.6.** **Arbitration** **.** Any and
      all disputes between the parties hereto arising out of this Agreement (other
      than disputes related to Article VI or to an alleged breach of the covenant
      contained in Article X) shall be settled by arbitration before an impartial
      arbitrator pursuant to the rules and regulations of the American Arbitration
      Association (AAA) pertaining to the arbitration of commercial disputes.
      Either party may invoke the right to arbitration. The arbitrator shall be
      selected by means of the parties striking alternatively from a panel of seven
      arbitrators supplied by the Chicago office of AAA. The Arbitrator shall have
      the
      authority to interpret and apply the provisions of this Agreement, consistent
      with Section 11.10 below. The decision of the arbitrator shall be final and
      binding upon the parties. Judgment may be entered on the award in any court
      of
      competent jurisdiction. The arbitrator’s fees and expenses shall be borne by the
      Company.




**11.7.** **Amendments** **.** This
      Agreement shall not be altered, amended or modified except by written instrument
      executed by the Company and the Executive.

**11.16.**  **Section
      409A Compliance** .




**11.16.1**  To
      the
      extent applicable, this Agreement shall be interpreted in accordance with
      Internal Revenue Code Section 409A and Department of Treasury regulations and
      other interpretive guidance issued thereunder. If the Company determines that
      any compensation or benefits payable under this Agreement do not comply with
      Code Section 409A and related Department of Treasury guidance, the Company
      and
      Executive agree to amend this Agreement or take such other actions as the
      Company deems necessary or appropriate to comply with the requirements of Code
      Section 409A while preserving the economic agreement of the
      parties.




**11.16.2** Notwithstanding
      any provision to the contrary in this Agreement, if Executive is deemed at
      the
      time of his separation from service to be a “specified employee” for purposes of
      Section 409A(a)(2)(B)(i) of the Code, to the extent delayed commencement of
      any
      portion of the benefits to which Executive is entitled under Section 5.1 or
      5.4
      of this Agreement




22
 
 is
        required in order to avoid a prohibited distribution under Section

        under Section 5.1 or 5.4 shall not be paid prior to the earlier of (a) the
        expiration of the six-month period measured from the date of Executive’s
        Separation from Service or (b) Executive’s death. Upon the expiration of the
        applicable Code Section 409A(a)(2)(B)(i) deferral period, all payments deferred
        pursuant to this Section 11.16 shall be paid in a lump sum and any remaining
        payments due under the Agreement shall be paid as otherwise provided herein.
        Notwithstanding anything herein to the contrary, to the maximum extent permitted
        by applicable law, amounts payable to Executive pursuant to Sections 5.1
        or 5.4
        herein shall be made in reliance upon Treas. Reg. Section 1.409A-1(b)(9)
        (Separation Pay Plans) or Treas. Reg. Section 1.409A-1(b)(4) (Short-Term
        Deferrals) and such amounts shall not be delayed pursuant to this Section
        11.16.2.




IN
      WITNESS WHEREOF, the Executive and the Company have executed this Agreement
      as
      of the date first above written.
