Dear Kathy:

This letter memorializes the agreement between you and Nicor, Inc., ("Nicor")
concerning your retirement. We wish to thank you for your service with the
company, and wish you the best in the years to come.

1.  Retirement Date And Last Day Of Employment. Your retirement will become
    effective on August 1, 2004. Until August 1, 2004, Nicor will continue to
    pay your current salary, less applicable taxes and payroll deductions, in
    accordance with regular payroll procedures, and you will continue to be
    eligible for employee benefits in accordance with applicable benefit plans,
    policies and practices. Thereafter, you will no longer (a) have any duties
    to perform for Nicor; (b) represent to third parties that you are authorized
    to act on Nicor's behalf; (c) have the authority to act on Nicor's behalf
    (and thus you will be without authority to bind or create liability on
    behalf of Nicor); and (d) have the authority to incur any expenses or
    obligations on behalf of Nicor.

2.  Consideration. If (i) no later than August 20, 2004, you sign, date and
    return a copy of this letter agreement and attachment A (which is
    incorporated and made part of this agreement) and (ii) you have not revoked
    attachment A, then you will receive the following benefits, which are over
    and above that to which you otherwise are entitled and are in exchange for
    your signing, not revoking and fully complying with this agreement: Under
    benefit plans or programs where age and/or service is relevant (including,
    but not limited to, Nicor's retirement plan, supplemental retirement
    benefits, and retiree healthcare), you will be credited with three
    additional years of age and three additional years of service for purposes
    of both benefit eligibility and benefit amount. For purposes of the
    Long-Term Incentive Program, Bonus Plan, Salary Deferral Plan, Savings
    Investment Plan, Supplemental Savings Investment Plan, Retiree Life
    Insurance Plan and Stock Deferral Plan, you will receive payments thereunder
    in accordance with the provisions applicable to retiring participants,
    except that exercisable option grants that you elect not to exercise on or
    before October 31, 2004 shall thereupon be converted to stock appreciation
    rights that will expire at the same time as the original option expiration
    date. In all other respect, the terms of the plans remain in effect and
    will control; providing, however, entitlement to benefits and/or payments
    to you or your beneficiaries under such plans shall begin on August 1, 2004.

<PAGE>

3.  Return Of Nicor Property And Information. As used in this section, the term
    "company information" means confidential, proprietary and/or any other
    information that belongs or relates to Nicor, including, without limitation,
    information received from third parties, and all other marketing, customer,
    potential customer, research and development, technical, business or
    financial information. Except as otherwise agreed to by you and Nicor, you
    agree that no later than August 1, 2004, you will return to Nicor all
    company information and related documents, reports, files (including all
    data stored in computer memory and/or other storage media), memoranda and
    records. You further certify that you have returned to Nicor all credit
    cards; portable computers and related equipment; card-key passes; door and
    file keys; computer access codes; software and all other physical property
    that you received, prepared or helped prepare in connection with your
    employment by Nicor. You also agree that you will not retain any copies,
    duplicates, reproductions or excerpts of the above items. You also agree to
    keep all company information confidential and thus will not disclose any
    company information to anyone unless you are compelled to do so by court
    order, provided that you furnish written notice to Nicor's General Counsel
    before disclosing the information.

4.  Non-Disparagement. You agree that you shall not -- directly or indirectly,
    individually or in concert with others -- interfere with, attempt to
    interfere with, take any actions or make any communications calculated or
    likely to have the effect of undermining, disparaging or otherwise
    reflecting negatively upon Nicor, its officers, directors, shareholders,
    employees, agents, operations, reputation, goodwill, services, safety
    record, business practices and/or customers. You also agree that, except as
    required by the express terms of a lawful subpoena or court order, you will
    never aid in any contemplated, threatened or actual litigation of any kind
    against Nicor. This agreement does not preclude you from providing truthful
    statements if called to testify under oath in any legal proceeding or to
    provide truthful information in any legal or administrative inquiry.

5.  Confidentiality Of Trade Secrets And Other Confidential Information. As used
    in this section, "trade secrets-confidential information" means, without
    limitation: customer lists of Nicor, Inc. and all related entities and
    affiliates, including but not limited to Nicor Gas, Nicor Energy, LLC, Nicor
    Solutions, Nicor Services, Nicor Enerchange, LLC, and EN Engineering
    (collectively, "Nicor" for purposes of this section); pricing of products
    and/or services; performance-based strategies; trading activities;
    marketing, technical and/or business information related to Nicor's
    marketing and/or business plans; analyses, techniques or strategies
    concerning actual or potential acquisitions and/or new ventures; development
    and/or introduction plans for products and/or services; unannounced products
    and/or services; operation costs; research and development processes; data
    relating to research, design, implementation and/or marketing of Nicor's
    products and/or services; the requirements and specifications of Nicor's
    agents, vendors, suppliers, trading partners, transporters, contractors
    and/or potential customers; financial information; business plans; marketing
    plans and strategies; quotations or proposals given to agents and/or
    customers and/or received from suppliers; methods for developing and
    maintaining business relationships with past, present or potential partners
    and/or customers; procedure manuals; employee training and review manuals;
    confidential personnel data; and all other information from which Nicor
    derives economic value and which is not generally available to the public.
    Excluded from the definition of "trade secrets - confidential information"
    is information that is generally known to the public.

                                       2

<PAGE>

    You agree that, during your employment, you have had special access to trade
    secrets-confidential information that constitutes a valuable and unique
    asset to Nicor. You agree that the energy industry is highly competitive,
    that Nicor has invested significant time and resources in developing trade
    secrets-confidential information, and that Nicor would suffer a significant
    economic loss if its trade secrets-confidential information were disclosed
    to Nicor's competitors and/or the general public. You also agree that Nicor
    does business throughout the Midwestern United States and that it has
    national interests in protecting its trade secrets-confidential information
    and safeguarding its customer and partner relationships.

    In light of the foregoing, upon your retirement from employment, you agree
    that you shall hold all trade secrets-confidential information in confidence
    and that you shall not make available or disclose in any way -- directly or
    indirectly -- trade secrets-confidential information to any person
    (including current or former Nicor employees), organization, newspaper or
    other media organization, employer, firm, partnership, association,
    corporation or business entity or use trade secrets-confidential information
    to your benefit or the benefit of another, except: (a) with the prior
    written consent of Nicor's General Counsel or (b) as compelled to do so by
    court order, provided that you give written notice to Nicor's General
    Counsel before disclosing the information. You acknowledge that the
    provisions of this section are reasonable and not unduly restrictive of your
    individual rights and you warrant that as of the date you sign this
    agreement you have not breached any of the provisions of this section. You
    also agree that, to the extent that they apply to your possession of trade
    secrets-confidential information, upon your retirement from employment you
    will continue to comply with all Nicor policy orders regarding or related to
    confidentiality and use of company assets.

    Finally, you agree that Nicor and all of its related entities (including its
    joint ventures) are this section's intended beneficiaries and that Nicor and
    all of its related entities are entitled to enforce this section as if they
    were signatories to it.

6.  Change In Control Agreement. This agreement entirely supersedes your Change
    in Control Agreement (executed by you on June 2, 2000), and irrevocably
    cancels all rights you have or may have to any change in control benefits or
    rights of any kind. You and Nicor further agree that the occurrence of any
    change in control to Nicor after August 1, 2004 will not create, perpetuate
    or increase any benefits or rights to which you otherwise are entitled.

7.  Cooperation. You agree that, after August 1, 2004, you will make yourself
    available to Nicor to provide reasonable cooperation, assistance,
    information and counsel with respect to areas and matters in which you were
    involved during your employment, including Nicor business matters and any
    threatened or actual litigation concerning Nicor. You acknowledge that this
    cooperation provision includes your attendance at matters that require you
    to travel.  Nicor agrees to promptly reimburse you for the actual expenses
    (including reasonable travel expenses) you incur as a result of complying
    with this provision, provided that you submit proper supporting
    documentation as reasonably required by Nicor.

                                       3

<PAGE>

    As part of this agreement, Nicor will provide you with reasonable access to
    financial and other records that you believe may be necessary to your
    defense of any pending or threatened legal proceedings relating to your
    employment at Nicor.

8.  Non-Admission And Tax Liability. You agree that this agreement does not
    constitute and shall not be construed, interpreted, or treated in any
    respect as an admission of any liability or wrongdoing by Nicor. You further
    agree that this agreement shall not be admissible in any proceeding without
    Nicor's written consent, except for a proceeding instituted by you or Nicor
    alleging a breach of this agreement, any proceeding in which a defense is
    asserted based on any provisions of this agreement, or as otherwise required
    by law.  You also agree that, if any taxing body determines that amounts
    should have been withheld from the payments provided for by section 2, you
    acknowledge and assume all responsibility for the payment of all such taxes
    and agree to indemnify and hold Nicor harmless for the payment of any such
    taxes and the failure to withhold.

9.  Indemnification. Nothing herein shall alter your rights to indemnification
    as set forth in, and Nicor's obligation as set forth in, Article Ten of the
    NICOR Inc. Articles of Incorporation Relating to Indemnification of
    Directors, Officers and Employees, a copy of which is attached and in effect
    on August 1, 2004.

10. Choice Of Law, Interpretation And Severability. You and Nicor agree that
    this agreement shall be governed by Illinois law. You and Nicor agree that
    this agreement shall not be construed against any party on account of
    authorship and, if a court finds any part of this agreement to be illegal or
    invalid, the illegal or invalid portion of the agreement shall be severed
    and the rest of the agreement will be enforceable.

11. Remedies. You agree that the exact amount of actual or potential damages to
    Nicor resulting from any breach of this agreement is inherently difficult to
    determine with precision and that any breach will result in immediate and
    irreparable harm to Nicor's business and goodwill, for which Nicor will have
    no adequate remedy at law. You agree that if you breach any of the
    provisions of this agreement, Nicor shall be entitled to seek injunctive
    relief, its actual attorneys' fees and costs associated with such action,
    and all such further relief as a court of competent jurisdiction may deem
    just and proper.

12. Heirs, Successors and Assigns. This agreement shall bind and benefit you and
    your heirs, estate, executors and administrators, and shall bind and benefit
    Nicor and its successors and assigns.

13. General Matters. You also agree that:

    - You have not suffered any on-the-job injury for which you have not already
      filed a claim and, except as set forth herein, you have been paid for all
      hours worked.

    - You are entering into this agreement knowingly and voluntarily and with
      full knowledge of its significance, and you have not been coerced,
      threatened, or intimidated into signing this agreement.

                                       4

<PAGE>

    - Nicor may assign this agreement, which will inure to the benefit of Nicor
      and its successors and assigns and any person or entity acquiring (whether
      by merger, consolidation, purchase of assets or otherwise) all or
      substantially all of Nicor's assets and/or business.

This agreement may be executed in two or more facsimiled counterparts, each of
which shall be equivalent to an original, but which collectively shall
constitute one agreement.

This agreement (including attachments A and B) sets forth the entire agreement
between you and Nicor regarding the end of your employment and supersedes any
written or oral understanding, promise or agreement that is not referred to and
incorporated in this agreement. This agreement may be changed only by a writing
signed by you and Nicor.

If you agree to all of the foregoing, please indicate your agreement by signing
and returning this letter to me. Please do not hesitate to contact me if you
would like further clarification regarding any aspect of this agreement or its
implementation. So there is no misunderstanding, this agreement will be deemed
to be withdrawn if for any reason I do not receive a signed copy of this
proposed agreement from you on or before August 20, 2004, unless otherwise
agreed in writing by Nicor.

Sincerely,

/s/ Claudia J. Colalillo

agreement; (d) you are hereby advised in writing to consult with an attorney
