                               LICENSING AGREEMENT

         This LICENSING AGREEMENT is dated January 21, 2000 and made effective
as of October 1, 1999, between World Wide Technology, Inc., a Missouri
corporation ("WWT"), and telcobuy.com LLC, a Delaware limited liability company
("TCB", each of WWT and TCB being a "PARTY" and together the "PARTIES").

                                    RECITALS

A.       TCB has been a division of WWT and is now a separate, majority-owned
         subsidiary of WWT. TCB provides an Internet source of material and
         information to telecommunications companies through the use of software
         and related technology licensed to or developed by WWT, and combined by
         WWT into the Global Portal Platform.

B.       Because  WWT's  ownership of TCB may be reduced,  the Parties  wish to
         state  formally the terms on which the Global Portal Platform will
         continue to be provided to TCB.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein, and other good and valuable consideration, the
receipt and adequacy of which is hereby acknowledged, the Parties agree as

or its successors, or (iii) 10 days after the closing of the sale or other

beneficial ownership of 100% of the combined voting power all of the equity
interests in TCB immediately prior to such sale or transfer do not, immediately
thereafter, own more than 50% of the combined voting power of all equity

                             ARTICLE 5. ENHANCEMENTS

5.1.     INCORPORATION OF ENHANCEMENTS. So long as the Global Portal Platform
         used by TCB is resident on the hardware maintained at the facilities of
         WWT, WWT shall have the right to incorporate any and all Enhancements
         to the Global Portal Platform made by WWT as part of the Global Portal
         Platform, without the payment of additional amounts to or by TCB,
         whether or not such Enhancements were made as the result of Consulting
         Services provided by WWT to TCB under the Management Services
         Agreement. Such Enhancements shall be subject to the provisions of this
         Agreement, including without limitation the confidentiality provisions
         and the provisions regarding the sole and exclusive ownership thereof
         by WWT.

5.2.     WWT RIGHT TO LICENSE ENHANCEMENTS. In the event that TCB requests that
         WWT make Enhancements to the Global Portal Platform, WWT and TCB shall
         mutually agree upon the terms upon which WWT shall perform such
         services, and TCB shall have the right to incorporate such Enhancements
         in the Global Portal Platform and to license or sub-license such
         Enhancements to third parties, consistent with the terms of this
         Agreement.

                      ARTICLE 6. TRANSFER TO TCB FACILITIES

6.1.     INSTALLATION AT TCB FACILITIES. The Global Portal Platform shall
         initially be resident and operated on hardware installed and maintained
         at the facilities of WWT. On not less than 90 days advance written
         Notice to WWT, TCB may elect to install a copy of the Global Portal
         Platform to hardware installed and maintained at the facilities of TCB.

6.2.     DELIVERY OF SOURCE CODE. At the time of such installation of the Global
         Portal Platform at the facilities of TCB, WWT shall provide TCB with a
         copy of the source code for the portions of the Global Portal Platform
         for which WWT has the legal right to do so (the "WWT SOURCE CODE"). The
         use of the WWT Source Code by TCB shall be subject to the limitations
         set forth in Article 7 of this Agreement. WWT and TCB shall jointly

                                       2

<PAGE>   3

         select an escrow agent (the "ESCROW AGENT") and shall enter into a
         source code escrow agreement with such Escrow Agent on terms mutually
         agreeable to the parties thereto (the "ESCROW AGREEMENT"). WWT shall
         place one copy of the WWT Source Code in escrow with the Escrow Agent,
         to be held by such Escrow Agent pursuant to the terms of the Escrow
         Agreement. The Escrow Agreement shall provide, among other things, for
         release of the WWT Source Code to TCB upon the written Notice from TCB
         that WWT has failed to provide TCB with a copy of the WWT Source Code
         as required under this Agreement, or upon the occurrence of any of the
         Events of Default by WWT described in paragraphs (a), (b), (c) or (d)
         of Section 13 of this Agreement. WWT shall update the WWT Source Code
         held by the Escrow Agent from time to time as required to keep a
         current copy of the WWT Source Code on deposit with the Escrow Agent.
         The costs and expenses of establishing and maintaining the WWT Source
         Code escrow and of updating the WWT Source Code deposit shall be shared
         equally by WWT and TCB.

6.3.     PROPRIETARY NOTICES. TCB shall not remove or alter any trademark,
         copyright, or other proprietary notice contained on or in the Global
         Portal Platform. WWT's copyright notice and other proprietary legends
         and labels affixed on the Global Portal Platform as delivered by WWT
         must also be affixed on and in all copies. The inclusion of a copyright
         notice on any software product or documentation shall not cause, or be
         construed to cause, it to be a published work.

6.4.     TRAINING AND MAINTENANCE. Upon WWT's receipt of written Notice from TCB
         under Section 6.1, WWT agrees to negotiate with TCB in good faith to
         reach agreement on the terms and conditions under which WWT will
         provide: (a) such training as may be reasonably required for TCB to
         operate and maintain the Global Portal Platform at its own facilities,
         and (b) future maintenance and support of the Global Portal Platform
         resident at the facilities of TCB.

6.5.     THIRD-PARTY LICENSES. TCB acknowledges and agrees that at the time of
         such installation of the Global Portal Platform at the facilities of
         TCB, TCB may be required to obtain its own licenses to third-party
         software products incorporated or integrated with or used in connection
         with the Global Portal Platform or provided by WWT as part of the
         Global Portal Platform, and that the procurement of such licenses shall
         be the sole responsibility and expense of TCB.

                     ARTICLE 7. INTELLECTUAL PROPERTY RIGHTS

7.1.     OWNERSHIP BY WWT. All of the Global Portal Platform and the media on
         which it may be delivered to TCB remain the sole and exclusive property
         and trade secret of WWT, except to the extent that the Global Portal
         Platform may contain or be derived from portions of materials provided
         by third party suppliers under license to WWT. Notwithstanding anything
         in this Agreement to the contrary, the parties acknowledge and agree
         that, except for such rights as are expressly granted to TCB hereunder
         and such rights of third parties described above, WWT has and shall
         have all right, title and interest, including all copyrights and
         property rights, in and to the Global Portal Platform, and all

                                       3
<PAGE>   4
         Enhancements thereto, whether developed by or on behalf of WWT or TCB,
         and all Intellectual Property Rights related thereto and all economic
         benefits resulting therefrom. Nothing in this Agreement, nor any other
         act or omission of WWT, shall be construed as a grant, transfer,
         conveyance, assignment or concession by WWT, or the consent by WWT to
         any such grant, transfer, conveyance, assignment or concession, to TCB
         of any copyright, property right, ownership or other proprietary right
         in the Global Portal Platform, any Enhancements thereto developed by or
         on behalf of WWT or TCB, the Intellectual Property Rights related
         thereto, or the economic benefits resulting therefrom.

7.2.     DERIVATIVE WORKS. Following the delivery of the source code to TCB
         pursuant to Section 6.2 hereof, TCB may create derivative works of the
         Global Portal Platform and will own all right, title and interest in
         and to such derivative works and the intellectual property rights
         thereto, and may use such derivative works to the same extent that TCB
         is entitled to use the Global Portal Platform.

                        ARTICLE 8. RESTRICTIVE COVENANTS

8.1.     COVENANT BY WWT. For so long as TCB has the right to use the Global
         Portal Platform under this Agreement, WWT agrees that it shall not,
         directly or indirectly, use, or authorize or allow others to use, the
         Global Portal Platform to provide products or services by any vendor or
         to any customer if such vendor or customer either (a) derives more than
         25% of its revenue from the provision of telecommunications products or
         services, or (b) generates annual gross revenue from the provision of
         telecommunications products or services in excess of $100,000,000 for
         the immediately preceeding calendar year.

8.2.     THIRD-PARTY OPPORTUNITIES.

         (a)      TCB shall have the right, at any time and from time to time,
                  to pursue opportunities to license the Global Portal Platform
                  to any third party in any field of use (a "THIRD-PARTY
                  OPPORTUNITY"). In the event that TCB is unable to conclude a
                  definitive agreement within a reasonable time with respect to
                  the Third-Party Opportunity, then TCB shall Notify WWT in
                  writing, describing in reasonable detail such Third-Party
                  Opportunity. Thereafter, WWT shall have the right to seek to
                  obtain a definitive agreement with respect to the Third-Party
                  Opportunity.

         (b)      In the event that WWT becomes aware of any Third-Party
                  Opportunity, WWT shall Notify TCB in writing of such
                  Third-Party Opportunity, describing in reasonable detail such
                  Third-Party Opportunity. WWT shall not pursue such Third-Party
                  Opportunity unless TCB does not conclude a definitive
                  agreement with respect to such Third-Party Opportunity within
                  a reasonable time after having received Notice thereof from
                  WWT.

                               ARTICLE 9. WARRANTY

9.1.     WARRANTY OF PERFORMANCE. Provided that TCB supplies the hardware and
         ancillary software required and approved by WWT and obtains from WWT
         maintenance and support of the Global Portal Platform resident at the
         facilities of TCB, WWT warrants that, for the Warranty Period, the
         Global Portal Platform will be free from material reproducible
         programming errors and defects in workmanship and materials, and will
         substantially conform to WWT's user documentation, when maintained and
         operated in accordance with WWT's instructions. If material
         reproducible programming errors are discovered during the Warranty
         Period, WWT shall promptly remedy them at no additional expense to TCB.
         This warranty to TCB shall be null and void if TCB is in default under
         this Agreement or if the nonconformance is due to: (a) hardware
         failures due to defects, power problems, environmental problems or any
         cause other than the Global Portal Platform itself; (b) modification of
         the Global Portal Platform by any party other than WWT; or (c) misuse,
         errors or negligence of TCB, its employees or agents in operating the
         Global Portal Platform.

9.2.     REIMBURSEMENT OF WWT EXPENSES. If WWT reasonably determines that the
         Global Portal Platform for which TCB's requested warranty service is
         not eligible for warranty service, TCB shall pay or reimburse WWT for
         all reasonable costs of investigating and responding to such request at
         WWT's then prevailing time and materials rates.

9.3.     LIMITATIONS. THE WARRANTIES OF WWT CONTAINED IN THIS AGREEMENT ARE
         EXCLUSIVE. THEY ARE IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR
         IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTY OF
         MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE OR
         NON-INFRINGEMENT, OR ARISING BY STATUTE OR OTHERWISE IN LAW OR FROM A
         COURSE OF DEALING OR USAGE OF TRADE. WWT'S SOLE OBLIGATION AND TCB'S
         EXCLUSIVE REMEDY FOR ANY WARRANTY FAILURE IS THE CORRECTION OR
         REPLACEMENT, AT WWT'S OPTION, OF THE NONCONFORMING PORTION OF THE
         GLOBAL PORTAL PLATFORM. NOTWITHSTANDING ANY OTHER PROVISION OF THIS
         AGREEMENT, AND IRRESPECTIVE OF ANY FAULT OR NEGLIGENCE, WWT SHALL NOT
         BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR
         PUNITIVE DAMAGES (INCLUDING WITHOUT LIMITATION DAMAGES FOR HARM TO
         BUSINESS, LOST REVENUES, LOST SALES, LOST SAVINGS, LOST PROFITS
         (ANTICIPATED OR ACTUAL), LOSS OF USE, DOWNTIME AND CLAIMS OF THIRD
         PARTIES), REGARDLESS OF THE FORM OF ACTION, WHETHER IN CONTRACT,
         WARRANTY, STRICT LIABILITY OR TORT (INCLUDING WITHOUT LIMITATION
         NEGLIGENCE OF ANY KIND, WHETHER ACTIVE OR PASSIVE), OR ANY OTHER LEGAL
         OR EQUITABLE THEORY, ALL WHETHER OR NOT WWT HAS BEEN APPRISED OR
         NOTIFIED THAT ANY SUCH DAMAGES OR LOSSES ARE POSSIBLE OR LIKELY, AND
         WHETHER OR NOT ANY PERMITTED REMEDY HAS FAILED ITS ESSENTIAL PURPOSE.

         following information which is "Confidential Information" whether
         acquired by it under or in connection with this Agreement or obtained
         in connection with the relationship of WWT and TCB or its predecessors
         regarding the Global Portal Platform before the Effective Date:

         (a)      information relating to the other Party's business, financial
                  condition or performance, or operations that the other Party
                  treats as confidential or proprietary;

         (b)      the terms and performance of, any breach under, or any Dispute
                  regarding this Agreement;

         (c)      the Parties' conduct, decisions, documents, and negotiations
                  as part of, and the status of, any Dispute resolution
                  proceedings under the Dispute Resolution Procedure;

         (d)      any information, business plan, concept, idea, know-how,
                  process, technique, program, design, formula, algorithm or
                  work-in-process, any engineering, manufacturing, marketing,
                  technical, financial, data, or sales information, or any
                  information regarding suppliers, customers, employees,
                  investors, or business operations, and any other information
                  or materials, whether in written, or graphic, or any other
                  form or that is disclosed orally, or electronically, or
                  otherwise which is learned or disclosed in the course of
                  discussions, studies, or other work undertaken between the
                  parties; and

         (e)      any other information, whether in a tangible medium or oral
                  and whether proprietary to the other Party or not, that is
                  marked or clearly identified by the other Party as
                  confidential or proprietary.

         (f)      Without limiting the generality of the foregoing, Confidential
                  Information shall include all information and materials
                  disclosed orally or in any other form, regarding WWT's
                  software products or software product development, including,
                  but not limited to, the configuration techniques, data
                  classification techniques, user interface, applications
                  programming interfaces, data modeling and management
                  techniques, data structures, and other information of or
                  relating to WWT's software products or derived from testing or
                  other use thereof.

         Neither Party may use any of the other Party's Confidential Information
         other than as required to perform its obligations or exercise its
         rights and remedies, including as part of the resolution of any
         Dispute, under this Agreement.

10.2.    EXCLUDED INFORMATION. A Party has no obligation under this Article 10
         regarding any information, including information that would otherwise
         by Confidential Information, to the extent that the information:

         (a)      is or becomes publicly available or available in the industry
                  other than as a result of any breach of this Agreement or any
                  other duty of that Party;

         (b)      is or becomes available to that Party from a source that, to
                  that Party's knowledge, is lawfully in possession of that
                  information and is not subject to a duty of confidentiality,
                  whether to the other Party or another Person, violated by that
                  disclosure; or

         (c)      is independently developed by employees of the receiving Party
                  who did not have access to the disclosing Party's Confidential
                  Information.

10.3.    STANDARD OF CARE. Each Party shall use the same degree of care in
         maintaining the confidentiality and restricting the use of the other
         Party's Confidential Information as that Party uses with respect to its
         own proprietary or confidential information, and in no event less than
         reasonable care.

10.4.    PERMITTED DISCLOSURES. A Party may disclose Confidential Information to
         its officers, directors, agents, or employees as necessary to give
         effect to this Agreement. Each Party shall inform each of these Persons
         to whom any Confidential Information is communicated of the obligations
         regarding that information under this Article 10 and impose on that
         Person the obligation to comply with this Article 10 regarding the
         Confidential Information. Each Party shall be responsible for any
         breach of that Party's obligations under this Article 10 by its
         officers, directors, agents, or employees.

10.5.    REQUIRED DISCLOSURES. Each Party may disclose Confidential Information
         in response to a request for disclosure by a court or another
         Governmental Authority, including a subpoena, court order, or
         audit-related request by a taxing authority, if that Party:

         (a)      promptly Notifies the other Party of the terms and the
                  circumstances of that request;

         (b)      consults with the other Party, and cooperates with the other
                  Party's reasonable requests, to resist or narrow that request;

         (c)      furnishes only information that, according to written advice
                  (which need not be a legal opinion) of its legal counsel, that
                  Party is legally compelled to disclose; and

         (d)      uses its Reasonable Efforts to obtain an order or other
                  reliable assurance that confidential treatment will be
                  accorded the information disclosed.

                                       7
<PAGE>   8
         A Party need not comply with these conditions to disclosure, however,
         to the extent that the request or order of the Governmental Authority
         in effect prohibits that compliance. A Party may also disclose
         Confidential Information without complying with these conditions to the
         extent that the Party is otherwise legally obligated to do so (for
         example, to comply with applicable securities laws), as confirmed by
         advice of competent and knowledgeable counsel. Further, a Party may
         also disclose Confidential Information, without complying with these
         conditions, in connection with a tax audit if the disclosure is to
         representatives of a taxing authority, or in connection with a tax
         contest if that Party uses its Reasonable Efforts to assure that
         confidential treatment will be accorded the information disclosed.

10.6.    TITLE TO INFORMATION. The Confidential Information of a Party disclosed
         by it to the other Party under this Agreement shall remain the property
         of the disclosing Party; nothing in this Agreement grants or conveys to
         the other Party any ownership or other proprietary rights in any of
         that Confidential Information.


10.7.    SURVIVAL; RETURN. The obligations under this Article 10 shall continue
         on and after Expiration or the termination of this Agreement. Upon
         request of the disclosing Party upon or after Expiration or the
         termination of this Agreement, the other Party shall return or, if
         requested by the disclosing Party, destroy the Confidential Information
         of the disclosing Party that it holds. The requested return or
         destruction shall include removal or deletion of Confidential
         Information from all data bases and magnetic media of the other Party.

                        ARTICLE 11. PARTIES' RELATIONSHIP

11.1.    INDEPENDENT. The Parties are independent; each has sole authority and
         control of the manner of, and is responsible for, its performance of
         this Agreement. This Agreement does not create or evidence a
         partnership or joint venture between the Parties. Neither Party may
         create or incur any liability or obligation for or on behalf of the
         other Party, except as described in this Agreement. This Agreement does
         not restrict WWT from providing or rendering any services or products,
         including services or products like the Global Portal Platform, to any
         other Person; nothing in this Agreement, however, gives WWT the right
         to provide or render any services or product in violation of any other
         agreement entered into by the Parties.

11.2.    EMPLOYEES. Except as described in Section 14.4(b) or Section 14.4(c)
         or, for the purposes of this Agreement:

         (a)      each Party is solely responsible for its own employees or
                  agents, including the actions or omissions and the
                  compensation of those employees and agents, and

         (b)      neither Party has any authority with respect to any of the
                  other Party's employees or agents.

                                       8
<PAGE>   9

11.3.    AUTHORITY AND ENFORCEABILITY.  Each Party warrants to the other Party
         that:

         (a)      it has the requisite corporate authority to enter into and
                  perform this Agreement;

         (b)      its execution, delivery, and performance of this Agreement
                  have been duly authorized by all requisite corporate action on
                  its behalf;

         (c)      this Agreement is enforceable against it; and

         (d)      it has obtained all consents or approvals of Governmental
                  Authorities and other Persons that are conditions to its
                  entering this Agreement.

11.4.    THIRD-PARTY LICENSES AND CONSENTS. Each Party shall be responsible for
         obtaining and maintaining any licenses, permits, consents, or approvals
         of Governmental Authorities and other Persons necessary or appropriate
         for it to perform its obligations under this Agreement.

11.5.    FURTHER ASSURANCES. Each Party shall take such actions, upon request of
         the other Party and in addition to the actions specified in this
         Agreement, as may be necessary or reasonably appropriate to implement
         or give effect to this Agreement.

                      ARTICLE 12. PARTIES' REPRESENTATIVES

12.1.    REPRESENTATIVES' AUTHORITY. Each Party has authorized its
         Representative to conduct discussions and negotiations, make and
         communicate decisions, frame and pose questions or issues, and resolve
         Disputes on behalf of that Party relating to this Agreement. Though one
         Party's employees or agents other than its Representative may also take
         actions of the kinds described in the preceding sentence with the other
         Party's employees or agents other than its Representative, matters that
         require more formal discussions or negotiations between Parties shall
         be addressed through and by the Representatives. Each Party and its
         Representative are entitled to rely on the actions and decisions of the
         other Party's Representative relating to this Agreement.

12.2.    DESIGNATION. WWT designates its Vice President and General Manager as
         WWT's Representative, and TCB designates its Chief Technology Officer
         as TCB's Representative, upon and after the Effective Date until
         changed by the designating Party. A Party may change its Representative
         by Notice to the other Party. A Party may rely on and deal with the
         Person who is designated as the other Party's Representative until any
         Notice of change is given by the other Party.

                          ARTICLE 13. EVENTS OF DEFAULT

13.1.    EVENTS OF DEFAULT. The following shall constitute "EVENTS OF DEFAULT"
         by a Party under this Agreement:

                                       9
<PAGE>   10
         (a)      such Party makes a general assignment of all or substantially
                  all of its assets for the benefit of its creditors;

         (b)      such Party applies for, consents to, or acquiesces in the
                  appointment of a receiver, trustee, custodian, or liquidator
                  for its business or all or substantially all of its assets;

         (c)      such Party files, or consents to or acquiesces in, a petition
                  seeking relief or reorganization under any bankruptcy or
                  insolvency laws; or

         (d)      a petition seeking relief or reorganization under any
                  bankruptcy or insolvency laws is filed against such Party and
                  is not dismissed within 90 days after it was filed;

         (e)      such Party's material breach of this Agreement which continues
                  uncured or uncorrected for 30 days after such Party's receives
                  Notice of such breach from the other Party, but if the
                  breaching Party (A) reasonably requires longer than 30 days to
                  cure or correct, and (B) Notifies the non-breaching Party of
                  the circumstances, then the cure period shall be extended for
                  the reasonable time so required, so long as during that time
                  the breaching Party diligently acts to effect that cure or
                  correction. Unless otherwise agreed in writing by the Parties,
                  no cure period extension shall exceed 90 days; and

         (f)      failure by TCB to pay any amount due to WWT under this
                  Agreement by the tenth Business Day after Notice of such
                  nonpayment has been given to TCB by WWT.

13.2.    CONSEQUENCES OF AN EVENT OF DEFAULT.

         (a)      Notwithstanding the occurrence of an Event of Default
                  hereunder or other breach by TCB of any legal duty or
                  obligation imposed by any contract (including this Agreement),
                  by the law of torts (including simple or gross negligence,
                  strict liability or willful misconduct), or by federal or
                  state laws, rules, regulations, orders, standards or
                  ordinances, WWT shall have no right to revoke or terminate,
                  through injunctive relief or otherwise, the license granted to
                  TCB under Article 3, it being understood and agreed that each
                  such breach shall be compensable, if at all, by a remedy at
                  law.

         (b)      Upon the occurrence of an Event of Default by WWT, TCB may
                  elect to terminate this Agreement, upon Notice to WWT
                  specifying the Termination Date.

13.3.    CONSEQUENCES OF TERMINATION BY TCB. Upon termination of this Agreement
         by TCB under Section 13.2(b), then during the Transition Period WWT
         shall comply, at WWT's expense, with TCB's reasonable requests for
         assistance in TCB's obtaining another solution having functionality
         substantially equivalent to the functionality of the Global


                                       10
<PAGE>   11

         Portal Platform in effect immediately preceding the Termination Date.
         Articles 8 and 17 shall apply in this situation as though this
         Agreement had not been terminated. If the records or other information
         provided by WWT are Confidential Information, Article 10 shall also
         apply as though this Agreement had not been terminated.

13.4.    SURVIVAL OF RIGHTS AND OBLIGATIONS. No rights or obligations of either
         Party that expressly or by implication are to remain in effect in order
         to give effect to this Agreement shall be impaired by the termination
         of this Agreement, and those rights and obligations shall remain in
         effect.

                       ARTICLE 14. LIABILITY AND REMEDIES

14.1.    WARRANTIES. Each Party's warranties in this Agreement are made solely
         to and for the benefit of the other Party. No Person other than a Party
         may make a claim based on the other Party's warranties under this
         Agreement.

14.2.    DEFICIENCIES. TCB shall promptly Notify WWT of any Deficiency in the
         Global Portal Platform. To the extent WWT agrees, or it is otherwise
         determined by the Dispute Resolution procedure, that any material
         portion of the Global Portal Platform was or is Nonconforming, WWT
         shall use its Reasonable Efforts promptly to cure or correct the
         Deficiency to the extent it may then be cured or corrected.

14.3.    ACTUAL DAMAGES. Neither Party shall be liable under or relating in any
         manner to this Agreement for any losses or damages other than Damages,
         even if a Party has been advised of the possibility of losses or
         damages of that kind and regardless of the form of the Proceedings or
         the theory of liability, whether based on contract, warranty, tort
         (including negligence and strict liability), infringement, or
         misappropriation.

14.4.    INDEMNITIES FOR CERTAIN BREACHES AND OTHER MATTERS. The following shall
         apply to any breach of, and certain other Damages relating to, this
         Agreement, other than a nonpayment by TCB of any amount relating to an
         invoice:

         (a)      each Party shall indemnify the other Party against all Damages
                  of the Indemnified Party, or any of its Indemnified Agents,
                  resulting from or relating to:

                  (i)      any breach of this Agreement, including breach of any
                           warranty in this Agreement, by the Indemnifying
                           Party;

                  (ii)     any Proceedings relating to a breach of this
                           Agreement by the Indemnifying Party; and

                  (iii)    the actions or omissions of the Indemnifying Party's
                           employees or agents under or in connection with this
                           Agreement.

         (b)      TCB shall also indemnify WWT against all Damages of WWT or any
                  of its Indemnified Agents resulting from or relating to any
                  sales, use, or similar taxes

                                       11
<PAGE>   12
                  (however described) applicable to TCB's use of the Global
                  Portal Platform, in whole or in part, that are assessed or
                  levied against or paid by WWT.

         (d)      The indemnification obligations in Sections 14.4(a) and
                  14.4(b) shall be extinguished to the extent that the Damages
                  of the other Party, or any of its Indemnified Agents for whom
                  or which the other Party is seeking indemnification, were
                  caused by the gross negligence (including recklessness) or
                  willful misconduct of the Person for whom or which
                  indemnification is sought. THE ORDINARY NEGLIGENCE OF A PERSON
                  OR THE JOINT OR CONCURRENT ORDINARY NEGLIGENCE OF PERSONS
                  SHALL NOT PRECLUDE THAT PERSON OR ANY OF THOSE PERSONS FROM
                  RECEIVING THE BENEFITS OF INDEMNIFICATION UNDER THIS
                  AGREEMENT.

         (e)      If an Indemnification Claim is not based on a Third-Party
                  Claim, the Indemnified Party shall give an Indemnification
                  Claim Notice promptly after the event constituting the basis
                  for the Indemnification Claim; its failure to do so, however,
                  shall relieve the Indemnifying Party of its indemnification
                  obligations only to the extent the Indemnifying Party is
                  actually prejudiced by that failure. If the Indemnified Party
                  gives an Indemnification Claim Notice regarding an
                  Indemnification Claim not based on a Third-Party Claim, the
                  Indemnifying Party shall Notify the Indemnified Party within
                  the Indemnification Response Period whether the Indemnifying
                  Party disputes all or any portion of the Indemnification
                  Claim. If the Indemnifying Party does not give that dispute
                  Notice or agrees to accept liability for all or a portion of
                  the Indemnification Claim, the Indemnification Claim, or the
                  agreed portion of that Indemnification Claim, shall be the
                  Indemnifying Party's liability. Otherwise, the Indemnification
                  Claim shall be deemed a Dispute to be resolved by the Dispute
                  Resolution Procedure.

         (f)      If an Indemnification Claim is based on a Third-party Claim:

                  (i)      The Indemnified Party shall give an Indemnification
                           Claim Notice promptly after it receives the
                           Third-Party Claim.

                  (ii)     The Indemnifying Party shall be entitled to defend
                           the Third-Party Claim, with its chosen counsel and at
                           its own expense, if (A) the Third-Party Claim seeks
                           only monetary relief against the Indemnified Party,
                           and (B) the Indemnifying Party elects to assume, and
                           diligently conducts, that defense. The Indemnifying
                           Party's election to defend shall be given by Notice
                           to the Indemnified Party within the Indemnification
                           Response Period. If the Indemnifying Party conducts
                           the defense, the Indemnified Party may participate in
                           that defense with its own counsel and at its own
                           expense.

                                       12
<PAGE>   13

                  (iii)    If the Indemnifying Party does not elect to defend
                           the Third-Party Claim by Notice within the
                           Indemnification Response Period, or if the
                           Indemnifying Party does not diligently conduct the
                           defense, the Indemnified Party shall be entitled,
                           upon further Notice to the Indemnifying Party, to
                           defend the Third-Party Claim on behalf of, and for
                           the account and risk of, the Indemnifying Party (if
                           it is determined that the Indemnifying Party has an
                           indemnification obligation regarding that
                           Indemnification Claim). In this circumstance, the
                           Indemnifying Party may participate in the defense
                           with its own counsel and at its own expense.

                  (iv)     If there is a conflict of interest that makes it
                           inappropriate for the same counsel to represent the
                           Indemnifying Party and the Indemnified Party in
                           defending the Third-Party Claim, the Indemnifying
                           Party shall pay for separate counsel for the
                           Indemnified Party.

                  (v)      The Indemnifying Party defending a Third-Party Claim
                           may compromise, settle, or resolve that Third-Party
                           Claim without the Indemnified Party's consent if the
                           compromise, settlement, or resolution involves only
                           the payment of money by the Indemnifying Party
                           (whether on its own behalf or behalf of the
                           Indemnified Party) and the third-party claimant
                           provides the Indemnified Party a release from all
                           liability regarding the Third-Party Claim. Otherwise,
                           the Indemnifying Party may not compromise, settle, or
                           resolve the Third-Party Claim without the Indemnified
                           Party's Reasonable Consent.

                  (vi)     The Indemnifying Party and the Indemnified Party
                           shall cooperate with all reasonable requests of the
                           other in defending any Third-Party Claim.

14.5.    TIME FOR CLAIMS.  A Party may make an Indemnification Claim:

         (a)      not based on a Third-Party Claim, only within two years after
                  the breach or other event constituting the basis for that
                  Indemnification Claim occurred, even if not discovered until
                  after that second anniversary, or

         (b)      based on a Third-Party Claim, at any time.

14.6.    OFFSET. A Party entitled to any payment due from the other Party under
         this Agreement may offset all or any portion of the amount of that
         payment against any payment that is due from it to the other Party
         under this Agreement.

14.7.    EXCLUSIVE REMEDIES. Except for the warranty provisions of Article 9,
         the termination right stated in Article 13 and the relief described in
         Sections 15.4 and 17.2(b) and in the Dispute Resolution Procedure, the
         remedies described in this Article 14 are the exclusive rights and
         remedies of a Party regarding any breach of this Agreement or any other
         matter that may be the subject of an Indemnification Claim.


                                      13

<PAGE>   14

14.8.    EQUITABLE RELIEF. Subject to the limitation set forth in Section
         13.2(a), to the extent that monetary relief is not a sufficient remedy
         for any breach of this Agreement, or upon any breach or impending
         breach of Article 10, the non-breaching Party shall be entitled to
         injunctive relief as a remedy for that breach or impending breach by
         the other Party, in addition to any other remedies granted to the
         non-breaching Party in this Agreement. That injunctive relief shall be
         sought through arbitration in accordance with the Dispute Resolution
         Procedure, except as permitted by Section B.4(b) of the Dispute
         Resolution Appendix.

14.9.    WAIVER OF REMEDIES. No forbearance, delay, or indulgence by either
         Party in enforcing this Agreement, within the applicable time limits
         stated in this Agreement, shall prejudice the rights or remedies of
         that Party. No waiver of a Party's rights or remedies regarding a
         particular breach of this Agreement constitutes a waiver of those
         rights or remedies, or any other rights or remedies, regarding any
         other or any subsequent breach of this Agreement.

14.10.   SURVIVAL. The rights, remedies, and obligations under this Article 14
         shall continue on and after Expiration or the termination of this
         Agreement.

                            ARTICLE 15. FORCE MAJEURE

15.1.    NO BREACH OR LIABILITY. No delay or failure of a Party to perform any
         of its obligations, other than payment obligations, under this
         Agreement due to causes beyond its reasonable control shall constitute
         a breach of this Agreement or render that Party liable for that delay
         or failure. Causes beyond a Party's reasonable control include:

         (a)      events or circumstances that the Party, using its Reasonable
                  Efforts, is unable to prevent or overcome; and

         (b)      labor disputes, strikes, or other similar disturbances; acts
                  of God; utilities or communications failures; acts of the
                  public enemy; and riots, insurrections, sabotage, or
                  vandalism.

15.2.    NOTICE OF EXCUSABLE DELAY OR FAILURE. If a Party anticipates any
         excusable delay or failure under Section 15.1, it shall promptly Notify
         the other Party of the anticipated delay or failure, the anticipated
         effect of that delay or failure, and any actions that are being or are
         to be taken to alleviate or overcome the cause of the delay or failure.

15.3.    EFFORTS TO OVERCOME. If a Party is claiming an excusable delay or
         failure under Section 15.1, it shall use its Reasonable Efforts to
         alleviate or overcome the cause of the delay or failure as soon as
         practicable.

15.4.    EXTENDED DELAY OR FAILURE. If an excusable delay or failure continues
         for more than 10 consecutive days, the Party entitled to the benefit of
         the affected obligation may, at its own expense, perform itself or
         obtain from any other Person the obligation to which that Party is
         entitled (and that Party shall Notify the other Party of this
         election).

                     ARTICLE 16. DISPUTE RESOLUTION MATTERS

16.1.    GENERAL PROCEDURES. Except as otherwise stated in this Agreement, the
         Parties shall resolve all Disputes in accordance with the Dispute
         Resolution Procedure. Nevertheless, if any Person other than the
         Parties:

         (a)      has initiated a lawsuit or other Proceedings against or
                  involving either or both of the Parties in which a Dispute
                  will be resolved, or

         (b)      is a necessary participant in any Proceedings to resolve a
                  Dispute and cannot be joined by either or both of the Parties
                  in an arbitration of that Dispute under Section B.3 of the
                  Dispute Resolution Appendix,

         so that (in either case) the Dispute Resolution Procedure is or will be
         ineffective, then the Parties need not use or follow the Dispute
         Resolution Procedure to resolve that Dispute, though the submission to
         jurisdiction in Section B.5 of the Dispute Resolution Appendix shall
         apply if necessary.

16.2.    CONTINUED PERFORMANCE. The Parties shall continue performing their
         respective obligations under this Agreement while a Dispute is being
         resolved.

16.3.    PARTIES' AGREEMENT. Nothing in this Article 16 or the Dispute
         Resolution Procedure prevents the Parties from resolving any Dispute by
         mutual agreement at any time.

                         ARTICLE 17. EXPENSES AND TAXES

17.1.    EXPENSES. Each Party shall be solely responsible for its costs and
         expenses incurred in performing its obligations and exercising its
         rights and remedies under this Agreement, except as otherwise provided
         in this Agreement.

17.2.    TAXES. The Parties shall be responsible for tax payments or liabilities
         relating to this Agreement as follows:

         (a)      Each Party shall be responsible for its income and franchise
                  taxes and for all other taxes (however described) based on its
                  own income or earnings.

         (b)      TCB shall be responsible for all sales, use, and similar taxes
                  (however described) applicable to the use by TCB of the Global
                  Portal Platform, in whole or in part. This obligation includes
                  TCB's paying the sales taxes identified in WWT's invoices
                  submitted to TCB.

                  (i)      If TCB claims an exemption or exclusion from taxes of
                           this kind, it shall deliver to WWT a certificate or
                           letter stating TCB's good-faith belief that its use
                           of the Global Portal Platform is not, in whole or in
                           part, subject to those taxes. Whether or nor TCB
                           delivers that certificate or letter, however, it
                           shall indemnify WWT, in accordance with Section
                           14.4(c)(iv),

                                      15
<PAGE>   16
                           against any taxes of this kind assessed or levied
                           against, or paid by, WWT and any other related
                           Damages of WWT.

                  (ii)     If WWT receives an assessment from a taxing authority
                           covering taxes for which TCB is responsible under
                           this Section 17.2(b), WWT shall Notify TCB of the
                           assessment and, at TCB's request, timely contest the
                           assessment. If payment to the taxing authority is
                           required by law as a condition to protest, TCB shall
                           timely furnish WWT the required amount for that
                           payment.

                  (iii)    If TCB believes it has overpaid taxes to WWT for any
                           of its use of the Global Portal Platform(in whole or
                           in part), TCB may require WWT to file a claim for a
                           refund at TCB's expense. If permitted by law, WWT may
                           assign any right to a refund directly to TCB instead
                           of filing a refund claim. Any refund of taxes
                           (including any interest) received by WWT under this
                           Section 17.2(b)(iii) shall be promptly forwarded to
                           TCB.

                  (iv)     Before WWT is required to pursue any action requested
                           by TCB under this Section 17.2(b), WWT may at any
                           time require TCB to deliver a letter of advice from
                           outside counsel (selected by TCB) stating that TCB's
                           tax position is reasonable.

                  (v)      Except as stated in the next sentence, any Dispute
                           between the Parties regarding the application of any
                           taxes of this kind to any use of the Global Portal
                           Platform by TCB (in whole or in part) shall be
                           resolved by the Dispute Resolution Procedure. Any
                           Dispute as to the amount of tax (if any) owed to a
                           taxing authority, including a Dispute between a Party
                           and the taxing authority, need not be resolved by the
                           Dispute Resolution Procedure, but may be resolved by
                           any appropriate administrative or legal procedure
                           available to a Party or the Parties under this
                           Agreement apart from the Dispute Resolution
                           Procedure.

         (c)      Each Party shall be responsible for all real property,
                  personal property, and other taxes (however described) based
                  on its owned or leased property, whether real or personal.

         (d)      Each Party shall be responsible for all employment-related
                  taxes (however described) regarding its own employees.

         Each Party shall cooperate with any reasonable request of the other
         Party to take any reasonable action to avoid or minimize any duplicate
         taxes that might be imposed; the requesting Party shall bear in the
         expenses of the other Party's compliance.

B.  DISPUTE RESOLUTION PROCEDURE.

1. GENERAL PROCEDURE. Except as otherwise stated in the Agreement, the Parties
shall resolve all Disputes in accordance with this procedure:

         (a)      Each Party shall instruct its Representative to promptly
                  negotiate in good faith with the other Party's Representative
                  to resolve the Dispute.

         (b)      If the Representatives do not resolve the Dispute within ten
                  Business Days (or such longer period as the Representatives
                  may agree) after the date of referral of the Dispute to them,
                  the Dispute shall be referred (by either or both of the
                  Representatives) to the Initial Executive Review Committee for
                  resolution.

         (c)      If the Initial Executive Review Committee does not resolve the
                  Dispute within ten Business Days (or such longer period as
                  that Committee may agree) from the date of referral to it, the
                  Dispute shall be referred (by that Committee or any of its
                  members) to the Second Executive Review Committee for
                  resolution.

         (d)      If the Second Executive Review Committee does not resolve the
                  Dispute within ten Business Days (or such longer period as
                  that Committee may agree) after the date of referral to it,
                  either Party may submit the Dispute for resolution by the

                                       24

<PAGE>   25

                  Parties' Presidents, who may submit the Dispute to non-binding
                  mediation in accordance with Section B.2 of this Dispute
                  Resolution Appendix.

         (e)      If the Dispute is not resolved by the parties' Presidents (if
                  submitted to them) and is not submitted to or resolved by
                  mediation, then either Party may submit the Dispute to binding
                  arbitration in accordance with Section B.3 of this Dispute
                  Resolution Appendix.

         A referral under any of Sections B.1(a), B.1(b), and B.1(c) of this
         Dispute Resolution Appendix shall be made by written Notice to the
         Persons designated in the applicable Section or Sections. That Notice
         shall be in a form described in the Agreement or an electronic mail
         message and addressed to each Person at his office address or
         electronic mail address; each Notice shall be given and effective as
         described in the Agreement or, in the case of electronic mail, upon
         actual receipt. The date of referral is the last date that Notice is
         given to all of the Persons to whom the Dispute must have been
         referred.

2. MEDIATION. The mediation of an unresolved Dispute shall be conducted in this
manner:

         (a)      Either Party may submit the Dispute to mediation by giving
                  Notice of mediation to the other Party. The Parties shall
                  attempt to agree upon and appoint a sole mediator who has the
                  Qualifications promptly after that Notice is given.

         (b)      If the Parties are unable to agree upon a mediator within ten
                  days after the date the Dispute is submitted to mediation,
                  either Party may request the St. Louis office of the American
                  Arbitration Association to appoint a mediator who has the
                  Qualifications. The mediator so appointed shall be deemed to
                  have the Qualifications and to be accepted by the Parties.

         (c)      The mediation shall be conducted in the St. Louis metropolitan
                  area at a place and a time agreed by the Parties with the
                  mediator, or if the Parties cannot agree, as designated by the
                  mediator. The mediation shall be held within 20 days after the
                  mediator is appointed.

         (d)      If either Party has substantial need for information from the
                  other Party in order to prepare for the mediation, the Parties
                  shall attempt to agree on procedures for the formal exchange
                  of information; if the Parties cannot agree, the mediator's
                  determination shall be effective.

         (e)      Each Party shall be represented in the mediation by at least
                  its Representative or another natural Person with authority to
                  settle the Dispute on behalf of that Party and, if desired by
                  that Party, by counsel for that Party. The parties'
                  representatives in the mediation shall continue with the
                  mediation as long as the mediator requests.

                                       25
<PAGE>   26
         (f)      Unless otherwise agreed by the parties, each Party shall pay
                  one-half of the mediator's fees and expenses and shall bear
                  all of its own expenses in connection with the mediation.
                  Neither Party may employ or use the mediator as a witness,
                  consultant, expert, or counsel regarding the Dispute or any
                  related matters.

3. ARBITRATION. The arbitration of an unresolved Dispute shall be conducted in
this manner:

         (a)      Either Party may begin arbitration by filing a demand for
                  arbitration in accordance with the Arbitration Rules. The
                  Parties shall attempt to agree upon and appoint a panel of
                  three arbitrators promptly after that demand is filed. Each of
                  those arbitrators must have the Qualifications, and at least
                  one of those arbitrators must be included in the Complex
                  Dispute List (unless no list of that kind is then maintained).

         (b)      If the parties are unable to agree upon any or all of the
                  arbitrators within ten days after the demand for arbitration
                  was filed (and do not agree to an extension of that ten-day
                  period), either Party may request the St. Louis office of the
                  American Arbitration Association to appoint the arbitrator or
                  arbitrators, who have the Qualifications (and at least one of
                  whom must be included in the Complex Dispute List, unless no
                  list of that kind is then maintained), necessary to complete
                  the panel in accordance with the Arbitration Rules. Each
                  arbitrator so appointed shall be deemed to have the
                  Qualifications and to be accepted by the Parties as part of
                  the panel.

         (c)      The arbitration shall be conducted in the St. Louis
                  metropolitan area at a place and a time agreed by the Parties
                  with the panel, or if the Parties cannot agree, as designated
                  by the panel. The panel may, however, call and conduct
                  hearings and meetings at such other places as the Parties may
                  agree or as the panel may, on the motion of one Party,
                  determine to be necessary to obtain significant testimony or
                  evidence.

         (d)      The Parties shall attempt to agree upon the scope and nature
                  of any discovery for the arbitration. If the Parties do not
                  agree, the panel may authorize any and all forms of discovery,
                  including depositions, interrogatories, and document
                  production, upon a showing of particularized need that the
                  requested discovery is likely to lead to material evidence
                  needed to resolve the Dispute and is not excessive in scope,
                  timing, or cost.

         (e)      The arbitration shall be subject to the Federal Arbitration
                  Act and conducted in accordance with the Arbitration Rules to
                  the extent they do not conflict with this Section B.3 of this
                  Dispute Resolution Appendix. The Parties and the panel may,
                  however, agree to vary the provisions of this Section B.3 of
                  this Dispute Resolution Appendix or the matters otherwise
                  governed by the Arbitration Rules.

                                       26
<PAGE>   27
         (f)      The panel has no power to:

                  (i)      rule upon or grant any extension, renewal, or
                           continuance of the Agreement;

                  (ii)     award remedies or relief either expressly prohibited
                           by the Agreement or under circumstances not permitted
                           by the Agreement; or

                  (iii)    grant provisional or temporary injunctive relief
                           before rendering the final decision or award.

         (g)      Unless the Parties otherwise agree, all Disputes regarding or
                  related to the same topic or event that are subject to
                  arbitration at one time shall be consolidated in a single
                  arbitration proceeding.

         (h)      A Party or other Person involved in an arbitration under this
                  Section B.3 may join in that arbitration any Person other than
                  a Party if:

                  (i)      the Person to be joined agrees to resolve the
                           particular dispute or controversy in accordance with
                           this Section B.3 and the other provisions of this
                           Dispute Resolution Appendix applicable to
                           arbitration; and

                  (ii)     the panel determines, upon application of the Person
                           seeking joinder, that the joinder of that other
                           person will promote the efficiency, expedition, and
                           consistency of the result of the arbitration and will
                           not unfairly prejudice any other party to the
                           arbitration.

         (i)      The arbitration hearing shall be held within 30 days after the
                  appointment of the panel. Upon request of either Party, the
                  panel shall arrange for a transcribed record of the
                  arbitration hearing, to be made available to both Parties.

         (j)      The panel's final decision or award shall be made within 30
                  days after the hearing. That final decision or award shall be
                  made by unanimous or majority vote or consent of the
                  arbitrators constituting the panel, and shall be deemed issued
                  at the place of arbitration. The panel shall issue a reasoned
                  written final decision or award based on the Agreement and
                  Missouri law; the panel may not act according to equity and
                  conscience or as an amicable compounder or apply the law
                  merchant.

         (k)      The panel's final decision or award may include:

                  (i)      recovery of Damages to the extent permitted by the
                           Agreement; or

                                       27


<PAGE>   28



                  (ii)   injunctive relief in response to any actual or
                         threatened breach of the Agreement or any other actual
                         or threatened action or omission of a Party under or in
                         connection with the Agreement.

         (l)      The panel's final decision or award shall be final and binding
                  upon the Parties, and judgment upon that decision or award may
                  be entered in any court having jurisdiction over either or
                  both of the Parties or their respective assets. The Parties
                  specifically waive any right they may have to apply or appeal
                  to any court for relief from the preceding sentence or from
                  any decision of the panel made, or any question of law
                  arising, before the final decision or award. If any decision
                  by the panel is vacated for any reason, the Parties shall
                  submit that Dispute to a new arbitration in accordance with
                  this Section B.3.

         (m)      Each Party shall pay one-half of the arbitrators' fees and
                  expenses, and shall bear all of its own expenses in connection
                  with the arbitration. The panel has the authority, however, to
                  award recovery of all costs and fees (including attorneys'
                  fees, administrative fees and the panel's fees and expenses)
                  to the prevailing Party in the arbitration.

4. RECOURSE TO COURTS. Nothing in the Dispute Resolution Procedure limits the
right of either Party to apply to a court or other tribunal having jurisdiction
to:

         (a)      enforce the Dispute Resolution Procedure, including the
                  agreement to arbitrate in this Dispute Resolution Appendix;

         (b)      seek provisional or temporary injunctive relief, in response
                  to an actual or impending breach of Article 10 of the
                  Agreement or otherwise so as to avoid irreparable damage or
                  maintain the status quo, until a final arbitration decision or
                  award is rendered or the Dispute is otherwise resolved; or

         (c)      challenge or vacate any final arbitration decision or award
                  that does not comport with Section B.3 of this Dispute
                  Resolution Appendix.

5. SUBMISSION TO JURISDICTION. Each Party irrevocably submits to the
jurisdiction of the federal courts of the United States and the state courts of
Missouri located in St. Louis County, Missouri. Each Party waives any defense or
challenge to that jurisdiction based on lack of personal jurisdiction, improper
venue, or inconvenience of forum.

6. CONFIDENTIALITY. The proceedings of all negotiations, mediations, and
arbitrations as part of the Dispute Resolution Procedure shall be privately
conducted. The Parties shall keep confidential all conduct, negotiations,
documents, decisions, and awards in connection with those proceedings under the
Dispute Resolution Procedure.
