         2.1      Confidentiality Obligations. During the Confidentiality
Period, the Receiving Party shall (i) protect the Confidential Information of
the Disclosing Party by using the same degree of care, but no less than a
reasonable degree of care, to prevent the unauthorized use, dissemination, or
publication of the Confidential Information as Receiving Party uses to protect
its own confidential information of a like nature, and (ii) not disclose such
Confidential Information to any Third Party, except as expressly permitted under
this Agreement, in the Transaction Agreements or in any other agreements entered
into between the parties in writing, without prior written consent of the
Disclosing Party.

         2.2      Disclosure To Representatives; Sublicensees. Notwithstanding
the provisions of Section 2.1, the Receiving Party may disclose the Confidential
Information to its Subsidiaries and Affiliated Companies, and its and their
directors, officers, employees, partners, affiliates, agents, financing sources,
rating agencies, advisors and representatives ("Representatives"), to the extent
such Representatives need to know such Confidential Information, and may
disclose to its sublicensees permitted under a Transaction Agreement portions of
Confidential Information as reasonably necessary in the exercise of the
Receiving Party's sublicense rights under such Transaction Agreement; provided,
however, that the Receiving Party shall inform each such Representative or
sublicensee of the confidential nature of the Confidential Information, shall
require such Representative or sublicensee to be bound to the terms of this
Agreement to the same extent as if such Representative or sublicensee was a
party hereto, and that the Receiving Party shall be responsible for any breach
of this Agreement by its Representatives and sublicensees.

         2.3      Compelled Disclosure. Notwithstanding anything to the contrary

compelled or otherwise legally obligated to disclose Confidential Information
(or portions thereof) (i) pursuant to subpoena or other court process; (ii) at
the express direction of any other authorized government agency with
jurisdiction over Receiving Party, or (iii) as otherwise required by law. If
Receiving Party becomes so compelled or obligated to disclose any of the
Confidential Information, Receiving Party will provide the Disclosing Party with
prompt written notice so that the Disclosing Party may seek a protective order
or other appropriate remedy. If such protective order or other remedy is not
obtained, Receiving


                                       3
   5


Party will furnish only that portion of the Confidential Information which, in
the opinion of Receiving Party's legal counsel, is legally required, and
Receiving Party will reasonably cooperate, at the Disclosing Party's expense and
request, with the Disclosing Party's counsel to enable the Disclosing Party to
obtain a protective order or other reliable assurance that confidential
treatment will be accorded the Confidential Information.

         2.4      No Restriction On Disclosing Party. Nothing in this Agreement
shall restrict the Disclosing Party from using, disclosing, or disseminating its
own Confidential Information in any way.

PROVIDED ON AN "AS IS, WHERE IS" BASIS AND THAT NEITHER PARTY NOR ANY OF ITS
SUBSIDIARIES OR AFFILIATED COMPANIES HAS MADE OR WILL MAKE ANY WARRANTY
WHATSOEVER, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY
IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE,

related to this Agreement shall be resolved in accordance with the dispute
resolutions procedures set forth in Section 5.7 of the Master Separation
Agreement.

         4.2      Proceedings. Notwithstanding the provisions of Section 4.1,
the parties hereto each acknowledge that any violation of this Agreement in
respect of any Confidential Information will cause the Disclosing Party and its
affiliates immediate and irreparable harm that monetary damages cannot
adequately remedy, and parties agree that, upon any actual or impending
violation of this Agreement, the Disclosing Party or any one or more


                                       4

injunctive relief and specific performance (and the Receiving Party shall not
plead in defense thereto that there would be an adequate remedy at law), without
bond or proof of damages, and in addition to any other remedies that the
Disclosing Party may have under applicable law. In the event of litigation
relating to this Agreement, if a court of competent jurisdiction determines that
Receiving Party or any of its Representatives has breached this Agreement,
Receiving Party shall be liable and pay to the Disclosing Party the reasonable
legal fees and costs incurred with such litigation, including any appeal
therefrom.

Information.

         6.2      Entire Agreement. This Agreement, the Master Separation
Agreement and the other Ancillary Agreements constitute the entire agreement
between the parties with respect to the subject matter hereof and shall
supersede all prior written and oral and all contemporaneous oral agreements and

foregoing, the parties agree that any agreements entered into between them on or
after the Separation Date for the protection of specific Confidential
Information shall supersede the terms of this Agreement with respect to such
Confidential Information.

         6.3      Governing Law. This Agreement shall be governed by and
construed and enforced in accordance with the laws of the State of Georgia as to
all matters regardless

of the laws that might otherwise govern under principles of conflicts of laws

in whole or in part, whether by operation of law or otherwise, assign or

or


                                       6
   8


transferees hereunder) may assign or transfer this Agreement as a whole
without consent to a Person that succeeds to all or substantially all of the
business or assets of such party. Without limiting the foregoing, this Agreement
will be binding upon and inure to the benefit of the parties and their permitted
successors and assigns.

         6.7      Severability. If any term or other provision of this Agreement
is determined by a nonappealable decision of a court, administrative agency or
binding arbitrator by any court or in any binding arbitration to be invalid,
illegal or incapable of being enforced by any rule of law or public policy, all
other conditions and provisions of this Agreement shall nevertheless remain in
full force and effect so long as the economic or legal substance of the
transactions contemplated hereby is not affected in any manner materially
adverse to either party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner to
the end that the transactions contemplated hereby are fulfilled to the fullest
extent possible.

         6.8      Failure Or Indulgence Not Waiver; Remedies Cumulative. No
failure or delay on the part of either party hereto in the exercise of any right
hereunder shall impair such right or be construed to be a waiver of, or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor shall any single or partial exercise of any such right preclude other or
further exercise thereof or of any other right. All rights and remedies existing
under this Agreement are cumulative to, and not exclusive of, any rights or
remedies otherwise available.

         6.9      Amendment. No change or amendment will be made to this
Agreement except by an instrument in writing signed on behalf of each of the
parties to such agreement.

         6.10     Counterparts. This Agreement may be executed in two or more
counterparts, all of which, taken together, shall be considered to be one and
the same instrument.
