2.1  Subject to the terms and conditions of this Agreement and to the rights and
licenses previously granted to third parties by Genuity of the type described in
connection with the Genuity Permitted Activities described in Exhibit A, from
and after the Effective Date, TELUS and its Affiliates shall and thereby have
the exclusive right and licence during the Term to use the Marks in connection
with the provision of Telecommunications Services in Canada, provided that such
Telecommunications Services are based on or use the Technology or are in lines
of business in which Genuity is or has been engaged at the time of use by TELUS.
Genuity agrees not to renew or extend such rights or licences after the
Effective Date unless permitted under Section 16.2.

2.2  Genuity warrants and represents that such rights and licenses to the Marks
previously granted to third parties will not prevent TELUS from (i) exclusively
using the Marks to represent
<PAGE>

                                      -4-

itself as the exclusive provider of Telecommunications Services in Canada using
the Technology, or (ii) exclusively using the Marks in connection with services
which provide a substantial competitive advantage to TELUS or materially
differentiate TELUS from its competitors in providing Telecommunications
Services. In view of the exclusive license granted to TELUS hereunder, Genuity
shall not renew or extend such rights or licenses after the Effective Date
unless permitted under Section 16.2.

2.3  Irrespective of the license granted to TELUS with respect to the Marks in
Section 2.1, Genuity acknowledges that TELUS has the exclusive right and license
to certain of the Marks pursuant to the GTE Agreement.

2.4  Genuity shall have the right to control the quality of any
Telecommunications Services described in section 2.1 and that TELUS advertises
and renders using the Marks, as more specifically described in Exhibit B hereto.

2.5  Subject to the restrictions in section 2.1 as to the right to use the
Marks, TELUS will have access to Genuity's existing creative, marketing,
advertising and other promotional materials for use in promoting
Telecommunications Services in Canada.  TELUS will not pay for the development
of such promotional materials, but will be responsible for any costs for
Canadian rights for talent, music, usage of third party intellectual property
rights, etc. TELUS may not significantly alter such materials without Genuity's
approval, such approval not to be unreasonably delayed or withheld, and will not
alter such materials without any required third party approvals.

2.6  Genuity shall use, and shall cause its Affiliates to use, commercially
reasonable efforts when obtaining from third parties licenses of trademarks,
service marks or promotional materials ("Third Party Property Rights") for the
purpose of providing Telecommunication Services, to obtain the right to sub-
license such Third Party Property Rights to TELUS.  Where Genuity obtains the
right to sub-license Third Party Property Rights to its Affiliates, Genuity
shall use commercially reasonable efforts to obtain the same for TELUS.  If
additional compensation is payable by Genuity to obtain such Third Party
Property Rights for TELUS, TELUS, should it decide to deploy such Third Party
Property Rights, will be responsible for such additional compensation and
Genuity will use commercially reasonable efforts to assist TELUS to obtain
favourable pricing or Genuity Affiliate pricing, whichever is lower.

2.7  TELUS will be obligated to use the Marks where TELUS reasonably concludes
that such use will enhance TELUS shareholder value.

3.  Technology
    ----------


3.1  License of Technology
     ---------------------

     Subject to the terms and conditions of this Agreement and to the rights and
licenses previously granted to third parties by Genuity of the type contemplated
by the Genuity Permitted Activities described in Exhibit A, from and after the
Effective Date, TELUS and its Affiliates
<PAGE>

                                      -5-

shall have the exclusive right during the Term to use, copy and modify the
Technology to provide Telecommunications Services in Canada.

     Genuity warrants and represents that such rights and licenses to the
Technology previously granted to third parties will not prevent TELUS from: (i)
being the exclusive provider of Telecommunications Services in Canada using the
Technology, or (ii) exclusively providing services which provide a substantial
competitive advantage to TELUS or materially differentiate TELUS from its
competitors in providing Telecommunications Services.  In view of the exclusive
license granted to TELUS hereunder, Genuity shall not renew or extend such
rights or licenses after the Effective Date unless permitted under Section 16.2.

     Irrespective of the license granted to TELUS with respect to the Technology
in this Section 3.1, Genuity acknowledges that TELUS has the exclusive right and
license to use certain of the Technology (including associated source code,
Third Party Technology and Third Party Property Rights) pursuant to the GTE
Agreement.

3.2  Source Code
     -----------

     Subject to the terms and conditions hereof, from and after the Effective
Date, Genuity shall make available and license to TELUS the right to use and
modify the source code for software which forms a part of the Technology.
Genuity shall not be required to sub-license or make available third party
source code for software which forms a part of the Technology to TELUS, except
to the extent that Genuity is authorized to sublicense or make available such
third party source code without payment of any additional compensation to any
third parties.  Genuity shall inform TELUS that such third party source code is
used in the Technology, shall consult with TELUS respecting its need for access
to and the right to use and modify such source code, and if TELUS determines
that it requires such source code or a contingent right to such source code,
then Genuity shall use commercially reasonable efforts to obtain access to and
the right to use and modify such source code or a contingent right to such
source code, as the case may be, for TELUS, without additional compensation, and
failing that with the compensation to be paid to any third party for such right
to be paid by TELUS.

3.3  Third Party Technology
     ----------------------

(a)  Notwithstanding any other provision of this Agreement, Genuity shall not be
     required to sub-license rights from third parties to patents, copyrights,
     trade secrets, know-how and supporting documentation or the right to use
     the foregoing ("Third Party Technology") to TELUS if any additional
     compensation is required to be paid to any third party for such right,
     provided that Genuity shall use and shall cause its Affiliates to use
     commercially reasonable efforts to obtain the right to sub-license such
     Third Party Technology to TELUS without the payment of any additional
     compensation to any such third parties, and failing that, to obtain the
     right to sub-license such Third Party Technology to TELUS or assist TELUS
     in obtaining the right directly, with any additional compensation to be
     paid by TELUS.
<PAGE>

                                      -6-

     If there are Third Party Property Rights generally included with the
license of any Third Party Technology, Genuity shall be required, subject to the
terms and conditions set out above in Section 3.3(a), to obtain the right to
sub-license such Third Party Property Rights to TELUS.


     If Genuity obtains Third Party Technology on an exclusive basis, Genuity
shall use reasonable commercial efforts to obtain a sublicense for TELUS on an
exclusive basis, subject to the terms and conditions set out above in Section
3.3(a).  If Genuity obtains Third Party Technology on a non-exclusive basis,
Genuity shall use reasonable commercial efforts to obtain a sublicense for TELUS
on a non-exclusive basis, subject to the terms and conditions set out above in
Section 3.3(a).

     In each of the above instances where TELUS is responsible for payment of
compensation to a third party, Genuity will use commercially reasonable efforts
to assist TELUS to obtain favourable pricing or Genuity Affiliate pricing,
whichever is lower.

3.4  Non-Tangible Technology
     -----------------------

     To the extent that the Technology consists of know-how or other proprietary
information which is not available in tangible form, Genuity shall share such
know-how and other proprietary information with TELUS.  In furtherance of this,
Genuity and TELUS shall jointly develop guidelines for providing TELUS with
access to Technology that consists of know-how and other non-tangible
proprietary information (which shall include the placement of TELUS
representatives with Genuity at TELUS' expense), provided that such access shall
be provided in a manner that minimizes the disruption to Genuity's business, as
determined by Genuity acting reasonably, and provided further that Genuity and
TELUS shall jointly determine when TELUS shall be required to compensate Genuity
for such access.  In making such determination, the parties agree to balance (a)
the need of TELUS, as a payer for the Technology, to have reasonable access to
Genuity personnel to ensure a meaningful transfer and understanding of the
Technology and its capabilities without Genuity charging for every inquiry and
contact, against (b) the need of Genuity to ensure that such assistance does not
result in its subsidizing TELUS' operations or in substantial disruption of
Genuity's business.

4.  Functional Services
    -------------------

4.1  Genuity will make Functional Services available to TELUS during the Term
and the Extended Term, upon TELUS' reasonable request, so as to enable TELUS to
provide Telecommunications Services in Canada based on or using the Technology
or to provide Telecommunications Services in Canada in lines of business in
which Genuity has been or is engaged at the time of TELUS' request, provided
that such Functional Services can reasonably be provided by Genuity, given the
availability of Genuity's resources at the time of TELUS' request.

4.2  Genuity will provide such Functional Services exclusively to TELUS in
Canada, provided that Genuity may also provide such Functional Services:
<PAGE>

                                      -7-

(a)  to third parties in Canada only to the extent that such Functional Services
     are part of Genuity's Permitted Activities in Canada; and

(b)  to third parties who are not providers of Telecommunications Services.

5.  Consulting Services
    -------------------

5.1  Subject to Section 7.1(b), Genuity will provide TELUS with consulting
services ("Consulting Services") reasonably requested by TELUS, during the Term
and the Extended Term including technical, marketing, training, support and
similar assistance to enable TELUS to provide Telecommunications Services in
Canada and to Canadian customers, based on or using the Technology or to provide
Telecommunications Services in Canada in lines of business in which Genuity is
engaged at the time of TELUS' request, including adapting the Technology for use
in Canada ("Canadianization"), provided that such Consulting Services can
reasonably be provided by Genuity, given the availability of Genuity's resources
at the time of TELUS' request.

6.  Payments
    --------

6.1  The parties agree that, in consideration for the rights granted to TELUS
under this Agreement, during the Initial Term, TELUS shall make payments to
Verizon in accordance with the terms of the GTE Agreement.  Genuity acknowledges
that, in addition to other good and valuable consideration provided to it under
this Agreement, it will derive benefits from TELUS' payments to Verizon.  The
parties further agree that such payments shall constitute sufficient
consideration to bind the parties to their obligations set forth in this
Agreement.   For greater certainty, Genuity hereby agrees that any dispute
between Verizon and Genuity shall not in any way adversely impact TELUS under
this Agreement.

6.2  [INTENTIONALLY DELETED]

6.3  [INTENTIONALLY DELETED]

6.4  Overdue payments will be subject to interest at the prime rate posted by
TELUS' principal Canadian bank.

except for any Functional Services or Consulting Services and payments earned
during the Term prior to termination.

6.6  Functional Services and Consulting Services are to be paid for by TELUS
based on agreed rates, which shall be usage-based, taking into account Genuity's
economies of scale, applicable laws and regulations, and the recovery of
Genuity's fully-loaded costs including, by way of example, reasonable
incremental costs experienced by Genuity (such as out-of-pocket costs such as
insurance, shipping or taxes, other than income taxes) not otherwise included by
Genuity in such internal pricing.

     process in connection with the proposed use of Technology to provide
     Telecommunications Services in Canada, and such input shall be considered
     by Genuity.

(d)  Genuity shall provide to TELUS support services customarily provided by
     Genuity to its own Affiliates in accordance with the principles set forth
     in Section 3.4.

     TELUS agrees that it will not challenge or otherwise contest Genuity's

     Technology owned by TELUS referred to in Section 9(b).
<PAGE>

                                      -9-

(b)  Subject to the prior ownership rights of Genuity in the Technology, TELUS
     shall own TELUS-funded or TELUS-developed enhancements and modifications to
     the Technology arising from Canadianization of the same.  TELUS hereby
     grants a non-exclusive, perpetual, irrevocable and royalty free license for
     such enhancements and modifications: (i) to Genuity for the provision of
     Telecommunications Services outside of Canada and to perform Genuity
     Permitted Activities, and (ii) to permit Genuity to grant and sub-license
     such enhancements and modifications to third parties for the provision of
     Telecommunications Services outside of Canada, provided that, where Genuity
     sub-licenses such enhancements and modifications to third parties, they
     shall be on terms mutually agreed to between TELUS and Genuity, and TELUS
     shall be compensated by Genuity for the use of such enhancements and
     modifications by third parties.  Genuity will own all other enhancements
     and modifications to the Technology, but they shall be made available to
     TELUS as part of the Technology under this Agreement. Nothing contained
     herein shall require TELUS to license such enhancements or modifications to
     third parties, or Genuity to license the Technology to third parties.

(c)  Genuity will apply for, prosecute to registration and maintain
     registrations in Canada for all intellectual property rights in the Marks,
     to the extent such protection is reasonably and commercially available in
     Canada,  and Genuity will apply for, prosecute to issuance and maintain
     statutory protection in Canada for intellectual property rights in the
     Technology as Genuity reasonably determines to pursue.  To the extent that
     Genuity has not sought intellectual property protection in Canada for the
     Marks or for the Technology and TELUS desires to seek such protection,
     TELUS may request Genuity to seek such protection and, to the extent that
     such protection is legally available in Canada, Genuity agrees to seek such
     protection at TELUS' expense.  TELUS and Genuity agree to cooperate with
     respect to securing such intellectual property protection.

limitations imposed on TELUS hereunder, TELUS may sub-license the Marks and

joint venture or marketing or strategic alliance, in each instance for the
provision of Telecommunications Services in Canada, provided that:

(a)  such sub-licenses shall be in writing and shall provide for a term not to
     exceed the Term, and shall prohibit further sublicensing without Genuity's
     consent;

(b)  such sub-licenses shall contain terms for the benefit of TELUS and Genuity
     no less favourable to TELUS and Genuity than the terms of Sections 2.4, 11,
     12, 14, 16 and 28 hereof;
<PAGE>

                                      -10-

(c)  where TELUS wishes to sub-license to a third party that is a material
     Competitor of Genuity, TELUS shall have obtained Genuity's prior written
     consent to such sub-license, provided that Genuity shall have first
     consulted with TELUS and attempted to reconcile its interest with that of
     TELUS regarding such licensee prior to deciding whether to provide its
     consent; and

(d)  such sublicense shall not include any Third Party Technology or Third Party
     Property Rights unless permitted pursuant to the agreement with the third
     party.

10.2  Sub-Licensing in Ordinary Course of Business:

     In addition to the sub-licenses permitted pursuant to Section 10.1, TELUS
may (but subject to the terms and conditions of Section 10.1) sub-license in the
ordinary course of business, provided that such sub-license shall not include
any Third Party Technology or Third Party Property Rights unless permitted
pursuant to the agreement with the third party:

(a)  any of the Technology to its customers to the extent required to enable
     such customers to use the Telecommunications Services provided by TELUS in
     Canada; and

(b)  any of the Marks to its dealers, distributors or other marketing or sales
     agents for the purpose of enabling them on behalf of TELUS to provide
     Telecommunications Services that are based on or using the Technology or
     are in lines of business in which Genuity has been or is engaged at the
     time of TELUS' grant of sublicense in Canada.

11.  Indemnification for Infringement
     --------------------------------

(a)  Subject to the terms hereof, in the event that use under this Agreement of
     the Marks or the Technology in Canada (excluding Third Party Technology and
     Third Party Property Rights) during the duration of this Agreement is the
     subject of a claim by a third party against TELUS for misappropriation of a
     third party trade secret or infringement of a patent, copyright, or other
     intellectual property right, Genuity shall defend (and at its option,
     settle), any legal proceeding brought against TELUS resulting from such
     claim, and indemnify TELUS with respect to any settled claims and damages
     finally awarded against TELUS as a result of such claim.

(b)  In addition to Genuity's obligations in Section 11(a), in the event of any
     such claim or in the event of a potential claim that would be reasonably
     likely to result in a substantial indemnity obligation on the part of
     Genuity, Genuity shall either:

     (i)   secure for TELUS the right to continue using the applicable Marks or
           Technology;
<PAGE>

                                      -11-

     (ii)  modify such Technology to make it non-infringing without materially
           changing functionality or performance; or

     (iii) replace such Technology with non-infringing comparable Technology
           without materially changing functionality or performance;

     If the foregoing are not reasonably available after Genuity has exercised
     diligent efforts to procure the same, upon the issuance of an injunction,
     or a final judgement, terminating or prohibiting continued use of the Marks
     or Technology as contemplated by this Agreement, Genuity may terminate the
     license to TELUS for such infringing component of the Marks or Technology
     and pay to TELUS a reasonable amount therefor, taking into account all
     relevant factors, including past use, if any, by TELUS of the infringing
     Marks/Technology.

(c)  It is agreed that Genuity shall have no obligation pursuant to Section
     11(a) to the extent that such claim would not have arisen but for:

     (i)   the use by TELUS of other marks or technology with the Marks or
           Technology;

     (ii)  modifications made to the Marks or Technology other than by Genuity
           or its suppliers; or

     (iii) the unreasonable failure of TELUS to use a current release of the
           Technology available to TELUS from Genuity after a reasonable
           transition period, if such infringement would have been avoided by
           the use of the current release, provided that Genuity offers such
           release to TELUS and advises TELUS that such release avoids the
           infringement.

(d)  TELUS shall give Genuity written notice of any such claims promptly after
     TELUS receives notice thereof; provided that the failure to give such
     notice shall not affect the rights of TELUS, except to the extent that
     Genuity shall have suffered actual damage by reason of such failure or such
     failure prejudices Genuity's ability to settle or defend such claim.

(e)  TELUS shall cooperate with and furnish reasonable assistance to Genuity in
     defense of all such claims.  TELUS may, at its own expense, have its own
     counsel act reasonably in consultation with Genuity in any proceeding,
     compromise or settlement which is under the direction of Genuity.

(f)  Notwithstanding anything in this Section 11 to the contrary, Genuity shall
     not, without TELUS' prior written consent, settle or compromise any claim
     where there is any reasonable probability that such action may either: (i)
     result in monetary damages in excess of the remaining balance available
     under the maximum liability; or (ii) materially and adversely affect TELUS
     by reason of the issuance of injunctive relief or a settlement that has the
     effect thereof.
<PAGE>

                                      -12-

(g)  Genuity shall keep TELUS informed of the status of the defense of all such
     claims and furnish TELUS with all documents, instruments and information
     that TELUS shall reasonably request.

(h)  Notwithstanding anything in this Section 11 to the contrary, Genuity's
     maximum aggregate liability to TELUS pursuant to Section 11(a) shall be
     $15 Million during the Initial Term and a maximum of $7.5 Million during
     any five year renewal of the Term; it being understood that TELUS shall be
     responsible for damages against TELUS in respect of claims by a third party
     in excess of the foregoing maximums and TELUS shall assume control of the
     defense and settlement of such claims.

(i)  With respect to Third Party Technology and Third Party Property Rights,
     Genuity shall have no liability to TELUS for infringement and TELUS' sole
     rights and recourse shall be as set forth in the agreement with the third
     party (or in the instance of a sublicense by Genuity, as permitted in
     Genuity's agreement with the third party).

(j)  The foregoing sets forth Genuity's entire liability for intellectual
     property infringement related to this Agreement.

12.  Warranties
     ----------

     Each of Genuity and TELUS has the requisite corporate power and authority
to execute and deliver this Agreement and to perform its obligations hereunder.

     The execution and delivery by each of Genuity and TELUS of this Agreement
and the fulfilment of its obligations under this Agreement have been duly
authorized by all necessary corporate action.

     The execution and delivery of this Agreement by each of Genuity and TELUS
does not, and the fulfilment by Genuity and TELUS of its obligations under this
Agreement will not, conflict with or violate any provision of its certificate of
incorporation or bylaws or conflict with, violate or result in the breach of any
provision of any material contract other than any such conflict, violation or
breach that would not have a material adverse effect.

     The use of the Technology and Marks is not the subject of current
litigation and is not the subject of a written charge of infringement received
by Genuity as of the date hereof.

     For a period of 6 months commencing on the date that any element of
Technology is installed at TELUS, or such longer warranty period as is
customarily provided by Genuity without the payment of additional compensation
to Genuity on the sale of such element of Technology to any third party, Genuity
shall warrant that such element of Technology, when properly installed and/or
used as designed for use by Genuity, shall materially conform to the then
current applicable specifications therefor, provided that (i) TELUS shall have
exercised
<PAGE>

                                      -13-

commercially reasonable efforts to remedy the problem itself before requesting
the assistance of Genuity and (ii) in the event that it is determined that the
problem was caused by the improper installation and/or use of the relevant
Technology by TELUS, then Genuity shall have the right to charge TELUS for its
services under Section 5 (Consulting Services). Notwithstanding the foregoing,
Genuity is not required to provide any warranty in respect of Technology
developed by it and which is (i) insignificant, and (ii) not generally made
available for commercial use or offered for sale to any person including third
parties, Affiliates or Genuity's own business units or divisions.

     Genuity makes no other warranties, either express or implied, as to the
condition of the Technology, their merchantability, their fitness for any
particular purpose, their non-infringement of third party rights, that any
Technology is error-free or that operation of any technology will be secure or
uninterrupted.

13.  Term, Termination and Post-Termination Rights/Obligations
     ---------------------------------------------------------

(a)  Unless there is early termination pursuant to this Section 13 during the
     Term, there shall be an initial term (the "Initial Term") starting from the
     Effective Date and ending at midnight (PST) on January 31, 2009. The
     Initial Term and any renewed term thereafter (the "Term") shall be
     automatically renewed for five years at the end of such Term, unless a
     party gives written notice to the other party two years prior to the end of
     the Term that it wishes to renegotiate, provided that any such
     renegotiation shall not be based solely on those matters set out in Section
     6.  Any renegotiation shall be concluded at least one year prior to the end
     of the Term, and if such re-negotiation cannot be concluded successfully,
     either party may at anytime at least one year prior to the end of the Term
     provide written notice to the other party that there shall be no renewal at
     the end of that Term.  If no such notice is received, the Term shall be
     automatically renewed as stated above.

(b)  Following the end of any Term without any renewal, or the termination of
     this Agreement for any reason, as the case may be, there shall be a two-
     year period (the "Extended Term") during which TELUS and Genuity will co-
     operate with each other to facilitate an orderly transition from the use of
     the Technology, and/or to alternate service providers, but TELUS shall not
     be entitled to use the Marks during the Extended Term.

(c)  Following the end of the Term or earlier termination of this Agreement (and
     the Extended Term), except as set forth below, TELUS will continue to
     retain the right to use, on a perpetual, irrevocable and royalty-free but
     non-exclusive basis, the Technology, including source codes, used by TELUS
     prior to the end of the Term or termination (including the Technology
     resident in and used by Genuity to provide Functional Services to TELUS) to
     provide Telecommunications Services in Canada.
<PAGE>

                                      -14-

     Following the termination of this Agreement by Genuity under Sections (f),
     (h) or (i), TELUS shall have the right to use the Technology (including
     source codes and the Technology resident in and used by Genuity to provide
     Functional Services to TELUS), on a royalty-free but non-exclusive basis,
     during the Extended Term only.

     Following the termination of this Agreement by Genuity under Section (l),
     TELUS shall have the following rights:

     (i)  where TELUS is acquired by a party or parties who do not fall within
          subsection (ii) below, TELUS shall have the rights set forth in the
          first paragraph of this Section 13(c) with respect to the Technology;
          or

     (ii) where TELUS is acquired by a party who is a material Competitor of
          Genuity, or is acquired by parties any one of whom is a material
          Competitor of Genuity and such material Competitor controls the
          acquiror, TELUS shall have the rights set forth in the second
          paragraph of this Section 13(c) with respect to the Technology, except
          that the term for the Extended Term shall be three (3) years.

(d)  Throughout the Extended Term, Genuity will continue to provide (and TELUS
     shall pay the prices in effect at the end of the Term for) Functional
     Services and will also provide such Consulting Services as requested by
     TELUS to assist it in its efforts to migrate from the Technology used by
     TELUS at the end of the Term or upon termination of this Agreement.
     Further, Genuity will provide limited Consulting Services for up to four
     years from the end of the Term or termination of this Agreement required
     for disaster recovery so as to maintain TELUS operations as at the end of
     the Term or termination of this Agreement and for source code changes to
     conform to exogenous factors (e.g. regulatory changes, change in industry
     standards, etc.)

(e)  [INTENTIONALLY DELETED]

(f)  [INTENTIONALLY DELETED]

(g)  TELUS shall have the right to terminate this Agreement (i) if Genuity fails
     (without cause) to provide TELUS with the rights to use the Marks or the
     Technology as provided herein after providing Genuity with notice and an
     opportunity to cure in accordance with Section 13(h), (ii) upon the
     termination of the GTE Agreement for any reason whatsoever, provided that
     TELUS shall provide Genuity with at least six months' prior written notice
     of such termination, or (iii) upon Genuity becoming an Affiliate of Verizon
     as a result of Verizon's conversion of Genuity's Class B common stock into
     Class C common stock or upon Genuity becoming an Affiliate of Verizon in
     any other manner.
<PAGE>

                                      -15-

(h)  Either TELUS or Genuity shall have the right to terminate this Agreement if
     the other party is in material breach of Section 15 or 16, and Genuity
     shall have the right to terminate this Agreement if TELUS is in material
     breach of Section 10, or if the sublicensee is in material breach of its
     sublicense from TELUS and TELUS fails to use commercially reasonable
     efforts to cause such sublicensee to cure the breach or, failing that,
     TELUS fails to terminate the sublicense, unless in any of such cases such
     breach is cured within 90 days after such party has received written notice
     of such breach.  Notwithstanding the foregoing, if the nature of the breach
     is such that it cannot reasonably be cured within such period, the party in
     breach shall have such longer period to cure such breach as may be
     reasonably necessary, provided that the party in breach diligently pursues
     such cure.

(i)  Should TELUS become bankrupt, or file a petition in bankruptcy, or if the
     business of TELUS should be placed in the hands of a receiver, assignee or
     trustee for the benefit of creditors, whether by the voluntary act of TELUS
     or otherwise, all licenses and rights granted herein to TELUS shall
     terminate/cancel automatically, unless stated otherwise in this Agreement.
     TELUS shall include in each sublicense equivalent provisions to this
     Section 13(i).

(j)  No waiver of any breach of, or default under, this Agreement shall
     constitute a waiver of any other breach of, or default under, this
     Agreement, and no waiver shall be effective unless made in writing and
     signed by an authorized representative of the party waiving the breach or
     default.

(k)  Termination/cancellation of this Agreement or the licenses and rights
     granted herein shall not relieve either party from any obligations that
     matured prior to the effective date of such termination/cancellation.  The
     termination/cancellation rights of each party provided herein are in
     addition to all other rights and remedies available to such party.

(l)  Either TELUS or Genuity shall have the right to terminate this Agreement if
     any person or any two or more persons (excluding Verizon, Genuity and any
     of their Affiliates) acting jointly or in concert shall acquire beneficial
     ownership, directly or indirectly, of more than 50% of the voting capital
     stock, or acquire all or substantially all of the assets, of TELUS.

(m)  Nothing contained in this Agreement (including the Exhibits) shall,
     following the termination or expiry thereof, be interpreted in any way to
     prejudice, limit or in any way derogate from, any rights which TELUS has or
     may have pursuant to the GTE Agreement, including without limitation any
     rights to the Marks and Technology.

14.  Confidentiality
     ---------------

(a)  Subject to Section 14(c), TELUS shall not use (except to the extent
     expressly permitted hereunder) and shall take reasonable precautions to
     prevent the
<PAGE>

                                      -16-

     disclosure of the Technology and all non-public documentation and
     information of Genuity, whether in written, electronic or other tangible
     form (the "Genuity Information") obtained by TELUS in the course of
     exploiting its rights or performing its obligations under, or in connection
     with entering into, this Agreement.

(b)  Subject to Section 14(c), Genuity shall not use (except to the extent
     expressly permitted hereunder) and shall take reasonable precautions to
     prevent the disclosure of all non-public documentation and information of
     TELUS, whether in written, electronic or other tangible form (the "TELUS
     Information") obtained by Genuity in the course of exploiting its rights or
     performing its obligations under, or in connection with entering into, this
     Agreement.

(c)  If either party is requested to disclose the Genuity Information or the
     TELUS Information as a legal requirement or as part of a legal or
     regulatory process, the party may make such disclosure provided that it has
     given prompt notice (to the extent that it is able to do so) to the other
     party so that the other party can seek a protective order or other
     appropriate remedy prior to such disclosure.

15.  Joint Marketing
     ---------------

(a)  The parties agree that it is their intention that TELUS shall be the
     vehicle for Genuity's strategy for the provision of Telecommunications
     Services in Canada. Subject to existing obligations, the parties will use
     reasonable efforts to appear to their respective customers as a single
     network with common user interfaces, and to provide products and services
     that are seamless with each other.

(b)  Each party shall negotiate in good faith and make reasonable efforts to
     agree to purchase Telecommunications Services for itself and its customers
     in the Other Party's Home Territory from the other party to the fullest
     extent practicable except to the extent otherwise required by law and
     subject to existing contracts at the Effective Date, Capability and
     commercial reasonableness, or where a customer specifically requests to use
     another service provider. In the event of any such exceptions, provided
     that the purchasing party has given the provisioning party the first
     opportunity to provide the required services, the purchasing party may make
     alternate arrangements to provide the Telecommunications Service in the
     Other Party's Home Territory, for that customer in those locations where
     the other party is unable to provide the services as required.

     For clarification purposes:

     (i)   "Capability" means the ability of the provisioning party to meet the
           purchasing party's availability and coverage requirements,
           requirements for commercially reasonable pricing and service delivery
           and performance standards, provided that such requirements and
           standards are commercially reasonable in the circumstances, and are
           no more onerous
<PAGE>

                                      -17-

           than the requirements and standards generally used by the purchasing
           party in its home territory for the provisioning of such
           Telecommunications Services. Such requirements and standards shall be
           reciprocal and the purchasing party shall be required to fulfil the
           same requirements and perform at the same standards when selling its
           equivalent services to the provisioning party.

     (ii)  Where TELUS is the purchasing party, it shall be entitled to terms
           and pricing from Genuity that are no less favourable than those
           offered by Genuity to its most favoured customers, including Verizon,
           but specifically excluding America Online.

     (iii) A party may use subcontractors to provide in whole or in part the
           Telecommunications Services that the other party seeks to purchase,
           provided that the provisioning party shall ensure that any such
           subcontractors perform in accordance with the requirements and
           standards of the purchasing party.

     (iv)  Where a purchasing party is entitled, after compliance with Section
           15(b), to make alternate arrangements for the provision of the
           required Telecommunications Services to a specific customer in the
           Other Party's Home Territory, by reason of the provisioning party not
           having the capability to meet the standard/general technical service
           delivery and performance standards of the purchasing party for the
           required Telecommunications Services, and not by reason of pricing or
           the requirements of the specific customer, in addition to its rights
           under Section 15(b), the purchasing party shall then be entitled to
           make alternate arrangements to meet such standard/general service
           requirements, but only on terms (including without limitation, scope
           and type of service, geographical coverage, customer and market
           segments), for a duration and at pricing no more favourable than
           those offered to the provisioning party, and provided that, prior to
           making such alternate arrangements, the purchasing party has
           consulted with the other party to determine whether the specific
           customer or general service requirements can be met in a manner that
           benefits both parties. If the provisioning party provides to the
           purchasing party a time period after which the provisioning party
           reasonably expects to be able to meet the standard/general technical
           service delivery and performance standards of the purchasing party,
           the purchasing party shall make alternate arrangements that may be
           ended at such time and shall use reasonable commercial efforts to
           migrate the services to the provisioning party after such time.

     (v)   The parties acknowledge and agree that Genuity shall provide
           Telecommunications Services to TELUS under Section 15(b) without any
           adjustment for TELUS' rights to use and modify the Technology.
<PAGE>

                                      -18-

(c)  In any negotiations of Genuity for an [*MATERIAL OMITTED AND SEPARATELY
     FILED PURSUANT TO AN APPLICATION FOR CONFIDENTIAL TREATMENT] for [*MATERIAL
     OMITTED AND SEPARATELY FILED PURSUANT TO AN APPLICATION FOR CONFIDENTIAL
     TREATMENT] of Telecommunications Services which ought reasonably to include
     a [*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT TO AN APPLICATION FOR
     CONFIDENTIAL TREATMENT] for [*MATERIAL OMITTED AND SEPARATELY FILED
     PURSUANT TO AN APPLICATION FOR CONFIDENTIAL TREATMENT], Genuity shall use
     commercially reasonable efforts and negotiate in good faith to obtain for
     [*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT TO AN APPLICATION FOR
     CONFIDENTIAL TREATMENT] the opportunity to [*MATERIAL OMITTED AND
     SEPARATELY FILED PURSUANT TO AN APPLICATION FOR CONFIDENTIAL TREATMENT] in
     such [*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT TO AN APPLICATION FOR
     CONFIDENTIAL TREATMENT] as [*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT
     TO AN APPLICATION FOR CONFIDENTIAL TREATMENT] of Telecommunications
     Services [*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT TO AN APPLICATION
     FOR CONFIDENTIAL TREATMENT] on substantially the same terms offered to
     other[*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT TO AN APPLICATION FOR
     CONFIDENTIAL TREATMENT].

16.  Non-Compete
     -----------

     From and after the Effective Date and during the Term:

16.1 Exclusivity of Licences in Canada
     ---------------------------------

     Except as specifically permitted in this Section 16 (provided however that
none of the following limitations shall prevent Genuity from engaging in the
Genuity Permitted Activities to the extent not prohibited by Section 16.2(c)),
Genuity will not, during the Term, sell, license or make available any of the
Marks or Technology, in each instance for the provision of Telecommunications
Services in Canada to any person other than TELUS.

16.2  Genuity Non-Compete in Canada
      -----------------------------

     Genuity will not directly or indirectly compete with TELUS in the provision
of Telecommunications Services in Canada, except that:

(a)  Genuity may offer Telecommunications Services (including the use of any of
     its Marks and Technology) in Canada to a non-American business customer who
     requires Telecommunications Services in Canada, if and only to the extent
     that (i) such services are specifically requested by that business customer
     without solicitation by Genuity as to the Telecommunications Services in
     Canada; (ii) such services are to be provided by Genuity to that customer
     ancillary to other Genuity Telecommunications Services outside of Canada to
     that customer or its Affiliates; and (iii) Genuity is unsuccessful in
     providing the Telecommunications Services in question through TELUS in
     accordance with Section 15(b);
<PAGE>

                                      -19-

(b)  Genuity may offer Telecommunications Services (including the use of any of
     its Marks and Technology) in Canada to an American business customer who
     requires Telecommunications Services in Canada if Genuity is unsuccessful
     in providing TELUS' Telecommunications Services to that customer in
     accordance with Section 15(b); and

(c)  Genuity may carry on in Canada the activities described in paragraphs 1 to
     6 inclusive in Exhibit A (the "Genuity Permitted Activities") including
     licensing Marks and Technology, provided that such activities do not
     prevent TELUS from (i) being the exclusive provider of Telecommunications
     Services in Canada using the Technology, or (ii) exclusively providing
     services which provide a substantial competitive advantage to TELUS or
     materially differentiate TELUS from its Competitors in providing
     Telecommunications Services in Canada (and for greater certainty, the sale
     or license or offering by Genuity of customer support, back office or
     similar services offered generally by Genuity to providers of
     Telecommunications Services in the U.S. which are Genuity's Competitors
     shall be conclusive evidence that such activities do not create any such
     prejudice.)

16.3  TELUS Non-Compete
      -----------------

     TELUS will not directly or indirectly compete with Genuity in the provision
of Telecommunications Services:

(a)  in the U.S.; or

(b)  outside Canada and the U.S. using any of the Marks or Technology, except
     for insignificant competition arising from and incidental to the provision
     of Telecommunications Services in Canada by TELUS.

     Notwithstanding the foregoing, TELUS may:

     (i)   carry on in the U.S. the activities described in Exhibit C (the
           "TELUS Permitted Activities");

     (ii)  offer Telecommunications Services (including the use of any of the
           Technology) in the U.S. to a non-Canadian business customer who
           requires Telecommunications Services in the U.S., if and only to the
           extent that (i) such services are specifically requested by that
           business customer without solicitation by TELUS as to the
           Telecommunications Services in the U.S.; (ii) such services are to be
           provided by TELUS to that customer ancillary to other TELUS
           Telecommunications Services outside of the United States to that
           customer or its Affiliates; and (iii) subject to the waiver in
           Section 17, TELUS is unsuccessful in providing the Telecommunications
           Services in question through Genuity in accordance with
           Section 15(b); and
<PAGE>

                                      -20-

     (iii) subject to the waiver in Section 17, offer Telecommunications
           Services (including the use of any of the Technology) in the U.S. to
           a Canadian business customer who requires Telecommunications Services
           in the U.S. if TELUS is unsuccessful in providing Genuity's
           Telecommunications Services to that customer in accordance with
           Section 15(b).


16.4  Subsequent Acquisitions
      ------------------------

(a)  The foregoing provisions do not prohibit the acquisition by a party or any
     of its Affiliates of an interest in any person or entity that would cause
     such party to be in breach of Section 16 if (i) such breach is [*MATERIAL
     OMITTED AND SEPARATELY FILED PURSUANT TO AN APPLICATION FOR CONFIDENTIAL
     TREATMENT]by the other party or (ii) promptly after the consummation of
     such acquisition, such party or Affiliate provides the other party with
     a[*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT TO AN APPLICATION FOR
     CONFIDENTIAL TREATMENT] to [*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT
     TO AN APPLICATION FOR CONFIDENTIAL TREATMENT] to the other party the
     portion of the [*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT TO AN
     APPLICATION FOR CONFIDENTIAL TREATMENT] or [*MATERIAL OMITTED AND
     SEPARATELY FILED PURSUANT TO AN APPLICATION FOR CONFIDENTIAL TREATMENT]
     relating to the [*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT TO AN
     APPLICATION FOR CONFIDENTIAL TREATMENT] for the portion of the [*MATERIAL
     OMITTED AND SEPARATELY FILED PURSUANT TO AN APPLICATION FOR CONFIDENTIAL
     TREATMENT] by the [*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT TO AN
     APPLICATION FOR CONFIDENTIAL TREATMENT] or [*MATERIAL OMITTED AND

     fairly allocated to such [*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT

(b)  Subject in all instances to the [*MATERIAL OMITTED AND SEPARATELY FILED
     PURSUANT TO AN APPLICATION FOR CONFIDENTIAL TREATMENT] party's obligations
     under Section 15(b), if the[*MATERIAL OMITTED AND SEPARATELY FILED PURSUANT

(c)  Prior to making any acquisition, a prospective offering party shall consult
     with the prospective offered party so that such party may provide input on
     the value of the Competing Business, its customers and assets, future
     business plans regarding the Competing Business and the service
     requirements of the customers of the Competing Business.


(d)  If, during the Term, Genuity enters into any business combination which
     materially increases the size and scope of Genuity's (or its successors')
     business or the marks or technology available to Genuity in connection with
     Telecommunications Services, Genuity will use commercially reasonable
     efforts to cause the other parties to such combination to grant to TELUS
     licences to such parties' marks and technology as part of the Marks and
     Technology, to the extent that they are not otherwise included in the Marks
     and Technology, without additional payment by TELUS.

16.5  Passive Ownership
      -----------------

     The foregoing provisions do not prohibit the ownership by any party for
passive investment purposes of less than 10% of the capital stock of any entity
providing Telecommunications Services in the Other Party's Home Territory.

16.6  Specific Performance
      --------------------

     The parties acknowledge and agree that the foregoing restrictions are
reasonable and necessary to protect the legitimate business interests of the
parties and that any violation of such restrictions would result in irreparable
harm to the parties and that the remedy for breach of this Section 16 shall
include, in addition to damages and any other remedy available at law or in
equity, the right to seek an order that the defaulting party and its Affiliates
shall immediately cease the prohibited activity.

17.  Conditions Subsequent
     ---------------------

     The parties acknowledge and agree that this Agreement shall be effective
and binding on the parties as of the Effective Date, unless on or before
October 15, 2000:

     (a) the parties fail to conclude a definitive amendment to this Agreement
with respect to the following matters:

         (i)   resolution of TELUS' potentially conflicting obligations to
               Verizon and Genuity for the duration of this Agreement;

         (ii)  TELUS' right to cure any defaults in payment that may occur
               between Verizon and Genuity;

         (iii) assurance that TELUS is not limited in the recourse and remedies
               that would otherwise be available to it if not for the payment
               mechanism in Section 6 in the event of any default by Genuity
               under this Agreement or
<PAGE>

                                      -25-

               default by Verizon under the GTE Agreement and assurance that
               such default under one agreement will not adversely affect TELUS
               under the other agreement, and assurance that Genuity is not
               limited in the recourse and remedies that would otherwise be
               available to it if not for the payment mechanism in Section 6 in
               the event of any default by TELUS or Verizon under the GTE
               Agreement which adversely affects Genuity under this Agreement;

         (iv)  clarification of Genuity's right to re-negotiate the payment
               mechanism in this Agreement in the event that the Genuity-Verizon
               arrangement as to payment ends by reason of Verizon selling or
               being unable to exercise its conversion rights with respect to
               Genuity's common stock, or in the event that the GTE Agreement
               terminates prior to the termination or expiry of this Agreement;
               and

         (v)   agreement on an updated version of Genuity Existing Contracts in
               Exhibit A; or

     (b)  TELUS and Verizon fail to conclude a definitive amendment to or
          replacement of the GTE Agreement, where such failure is not waived by
          TELUS at its sole discretion; or


     (c)  TELUS and Verizon conclude a definitive amendment to or replacement of
          the GTE Agreement in a manner that results in a strategic relationship
          between TELUS and Verizon that fundamentally deviates from the
          relationship set forth in the GTE Agreement as it existed on the
          Effective Date.

     In the event that (1) the parties fail to conclude a definitive amendment
with respect to the matters described in subparagraph (a) above, or (2) TELUS
and Verizon fail to conclude a definitive amendment to or replacement of the GTE
Agreement and such failure is not waived by TELUS, or (3) TELUS and Verizon
conclude a definitive amendment to or replacement of the GTE Agreement that has
the effect described in subparagraph (c) above and such condition (c) is not
waived by each of TELUS and Genuity, in each case on or before October 15, 2000,
this Agreement shall terminate automatically, and the parties shall be fully
released from their obligations under this Agreement.

     Notwithstanding any other provision herein to the contrary, in order to
avoid any conflict between TELUS' obligations under this Agreement and its
obligations under the GTE Agreement, for the period from the Effective Date
until such time that the parties conclude a definitive amendment to this
Agreement as contemplated in this Section 17, Genuity releases TELUS from its
obligations pursuant to Sections 15(a) and 15(b) of this Agreement to use
Genuity as its preferred provider of Telecommunications Services in the United
States.

18.  Allocation and Withholding Tax
     ------------------------------

     The parties agree to allocate the purchase price referred to in Section 6
between the properties, services and benefits to be provided to the parties
under this Agreement in a
<PAGE>

                                      -26-

reasonable and tax efficient manner, taking into account the fair market value
of each of the properties, services and benefits to be provided under this
Agreement. The parties will use their best efforts to make such allocation as
soon as possible after completing this Agreement and, in any event, prior to the
Effective Date. The Parties agree that the allocation referred to in this
paragraph will be used for all reporting purposes.

     All payments to Genuity under this Agreement will be subject to any
applicable Canadian withholding taxes, and any such taxes withheld from a
payment and remitted by TELUS or its Affiliates to the Canadian tax authorities
will be considered to be a payment in that amount to Genuity under this
Agreement.  TELUS shall provide Genuity with proof of payment to the Canadian
taxation authorities and shall use its best efforts to satisfy the U.S. Internal
Revenue Service that such payment has been made.

19.  Management of Strategic Relationship
     ------------------------------------

19.1 Executive Council
     -----------------

     The parties agree to designate senior executives to serve as members of a
committee (the "Executive Council") to take actions necessary to fulfill the
parties' obligations under this Agreement and address requests for waivers and
amendments of the provisions of this Agreement.  Either party may change its
representatives on such Executive Council at any time in its sole discretion and
shall make reasonable efforts to inform the other party of such change.  The
Executive Council shall be co-chaired by one representative of each party.  The
Executive Council shall be authorized to take all actions necessary to further
the principles and to mutually agree on how to implement all matters
contemplated by this Agreement.

     The Executive Council shall establish an administrative office (the
"Alliance Management Office") to oversee and coordinate the implementation and
ongoing administration of this Agreement.  The parties shall each designate one
representative who shall manage and operate the Alliance Management Office, each
of whom will be a senior representative of his/her respective organization.
Either party may change its representative at any time in its sole discretion
and shall make reasonable efforts to inform the other party of such change.  The
mandate of the Alliance Management Office is to oversee and coordinate, subject
to the direction of the Executive Council, the implementation of this Agreement
including, without limitation, coordinating the activities of any working groups
designated by the Executive Council and monitoring and reporting upon the
success of implementation activities.  The Executive Council shall also
establish such joint working groups as it deems necessary and desirable to
promote the effective implementation of this Agreement.

19.2 Dispute Resolution
     ------------------

     Either party shall refer any dispute in respect of this Agreement to the
Executive Council for resolution.  The Executive Council shall meet as soon as
is reasonably possible after a dispute is referred to it, giving due regard to
the nature and impact of the issue under consideration, to attempt to resolve
such dispute.  If a dispute cannot be resolved by the Executive Council by
unanimous action and mutual agreement within 20 days after submission to the
Executive Council, or such other time period that is acceptable to the parties,
either party may refer the
<PAGE>

                                      -27-

dispute to arbitration in accordance with Section 19.3. Nothing in this Section
19.2 shall prevent a party from taking any action for injunctive relief
permitted by Section 16.6 which such party concludes, in the exercise of its
sole discretion, is necessary to preserve its rights or benefits, including
preserving the status quo, pending resolution of a dispute.

19.3  Arbitration
      -----------

     The arbitral proceedings shall be confidential, and any information
disclosed therein shall be treated by the parties as proprietary and
confidential information in accordance with the provisions of Section 14.  There
shall be three arbitrators to be selected as follows, one arbitrator shall be
selected by the petitioning party ("Petitioning Party"), one arbitrator shall be
selected by the party defending the arbitration ("Defending Party"), and the
third arbitrator shall be selected by the two arbitrators selected by the
Petitioning Party and the Defending Party, or, if such arbitrators cannot agree
within 30 days on the third arbitrator, such arbitrator will be selected by the
International Chamber of Commerce ("ICC") pursuant to ICC rules.  The
arbitration shall take place in Vancouver and shall be administered by the ICC.
In the event that the Defending Party within 30 days of any notification made to
the Defending Party of the demand for arbitration by the Petitioning Party
(containing the name, address and profession of the arbitrator selected, the
subject matter of the dispute and the relief sought) does not name its
arbitrator (providing the same information), such arbitrator shall be appointed
by the ICC at the request of the Petitioning Party.

20.  Legal and Other Compliance
     --------------------------

     This Agreement and the relationship of the parties is subject to compliance
with all applicable laws, including export control laws.


     TELUS shall obtain all regulatory consents, approvals or licenses necessary
to offer Telecommunications Services in Canada using any of the Marks or
Technology.

21.  Obligations of Covenantor
     -------------------------

     During the term of this Agreement, Covenantor guarantees the obligations of
Genuity  hereunder.  If, during the term of this Agreement, Genuity Solutions
Inc. ceases to be an Affiliate of the Covenantor, the Covenantor shall thereupon
automatically become the primary contracting party to this Agreement in place of
Genuity Solutions Inc.  For the purposes of clarification, any entity that is or
becomes an Affiliate of Genuity at any time during the term of this Agreement
shall be considered to be an Affiliate of Genuity for the purpose and duration
of this Agreement.



22.  Binding Agreement

agreement among the parties and, subject to Sections 13(m) and 17 hereof,

agreement between the parties with respect to the subject matter of this
Agreement and supersedes any prior or contemporaneous negotiations, proposals,
understandings or agreements between the parties with respect to the subject
matter hereof. No modification, amendment or alteration of this Agreement shall
be effective, unless set forth in a writing signed by the duly authorized
representatives of the parties.

     Each of the parties shall be responsible for its own fees and other
expenses incurred with respect to the negotiation of this Agreement, the
agreements contemplated hereby and the closing of this transaction.

23.  Public Announcements
     --------------------

     Each of the parties agrees not to make any public announcements concerning
the proposed transaction or the related negotiations without the prior approval
of the other party, except as may be required by law or applicable stock
exchange rules, in which case disclosure may only be made after making all
reasonable efforts to advise the other party of such disclosure and to obtain
their comments prior to making such disclosure.

     Neither TELUS nor Genuity shall assign or transfer directly or indirectly
(including to a Competitor of Genuity by merger or operation of law) any of its
rights and obligations, except with the prior written consent of the other
party; provided that nothing in this section shall prohibit:

(a)  either party from assigning or transferring this Agreement to an Affiliate;
     or

(b)  TELUS from granting a sub-license in accordance with Section 10.

27.  No Partnership
     --------------

     This Agreement is not intended, nor should anything herein be construed, to
create the relationship of partners, principal and agent, or employer and
employee among or between any parties.  No party shall have any authority to
represent or to bind any other party in any manner whatsoever, and each party
shall be solely responsible and liable for its own acts.

     If any one or more of the provisions contained in this Agreement shall be
invalid, illegal or unenforceable in any respect under any applicable law, the
validity, legality, and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired.

          TRADEMARK LICENSING AND OTHER PROVISIONS REGARDING SERVICES


1.  Genuity has the right to control the quality of any Telecommunications
    Services that TELUS advertises and renders in connection with the Marks as
    specifically described in this Section 1.

    (a)  TELUS agrees that it shall maintain standards of quality in the
         advertising and rendering of the Telecommunications Services under this
         Agreement consistent with those prevalent in the telecommunications
         industry in Canada. TELUS agrees that it shall not advertise or render
         under the Marks any Telecommunications Services that do not meet such
         quality standards.

    (b)  TELUS agrees that it will not utilize the Marks or any confusingly
         similar trademarks, service marks, trade names or domain names, except
         in connection with the Telecommunications Services and then only during
         the Term and as permitted hereunder.

    (c)  TELUS agrees to allow Genuity or Genuity's authorized representative at
         reasonable times upon reasonable notice to enter the premises of TELUS,
         or any premise under the control of TELUS, to inspect the services in
         connection with which the Marks are used by TELUS. Such an inspection
         shall be at Genuity's expense.

    (d)  TELUS agrees that the style and manner of use of the Marks in
         connection with the advertising and rendering of the Telecommunications
         Services shall be in the form, style and manner as may be reasonably
         approved by Genuity in writing from time to time.

    (e)  TELUS agrees to use with the Marks any and all legal notices evidencing
         ownership of and/or registration by Genuity of the Marks as may be
         reasonably required by Genuity.

    (f)  Without prejudice to TELUS' right of indemnity pursuant to Section 11,
         TELUS agrees that it will not challenge or otherwise contest the right
         of Genuity to register the Marks during the Term.

    (g)  TELUS agrees that nothing herein shall give TELUS any right to or
         interest in the Marks, except the right to use the same in accordance
         with the terms of this Agreement, and that all and any uses of the
         Marks by TELUS shall inure to the benefit of Genuity.
<PAGE>

    (h)  TELUS agrees that it will not hereafter seek registration of the Marks
         in its own name or in the name of an Affiliate.

    (i)  TELUS agrees to cooperate reasonably with Genuity, at Genuity's
         expense, in the procurement of any registration of the Marks which
         Genuity may choose to undertake at Genuity's sole discretion, including
         but not limited to supplying evidence of use of the Marks to Genuity.

    (j)  TELUS agrees to provide within a reasonable period of time written
         notice to Genuity of any conduct on the part of third parties which
         TELUS deems to be an infringement of the Marks or Technology in Canada
         or a challenge to the validity of any registration of an intellectual
         property right in same. Genuity shall have a period of sixty (60) days
         from the date of TELUS' notice in which to determine whether or not
         Genuity elects to bring an action for infringement of the Marks or
         Technology or the defence of any registration of same, and to advise
         TELUS in writing of Genuity's decision. In any action brought by
         Genuity, the action will be brought in the name of TELUS and Genuity.
         The failure of Genuity to advise TELUS of Genuity's decision shall be
         treated as a decision by Genuity not to take any action against such
         third parties.

     If Genuity elects not to take any action against such third parties, TELUS
has the right to bring an action for infringement of the Marks, or to take any
other action related to the Marks, against such third parties. In any action
brought by TELUS, the action will be brought in the name of TELUS and Genuity,
shall be at the sole cost and expense of TELUS, including all out-of-pocket
expenses of Genuity, and Genuity shall co-operate reasonably with TELUS in
respect of such action.

     If Genuity decides to take action against such third parties, Genuity will
pay all costs and expenses, including all attorney's fees.  If Genuity and TELUS
both decide to take such action, each of Genuity and TELUS will pay all of their
own respective costs and expenses, including attorney's fees.  If only TELUS
decides to take such action, TELUS will pay all of its cost and expenses,
including all attorney's fees.

     In all such actions:  (i) except where Genuity has decided not to take any
action, Genuity shall control the litigation, acting reasonably, in consultation
with TELUS; (ii) if Genuity has decided not to take any action, TELUS shall
control the litigation, acting reasonably in consultation with Genuity; and, in
any event (iii) no settlement shall be made by either party without the consent
of the other party, such consent not to be unreasonably withheld.

2.  Nothing contained in this Agreement shall be construed as conferring by
implication, estoppel or otherwise any license or other right under any
trademark except as expressly granted herein.
