modifications to the Development Services, Milestone Schedule, Requirement
Specification, Business Regulations, Development Plan, and/or any other
activities hereunder (a "Change") may be necessary. In the event that either MCI
or UTS determines that a Change is necessary, the determining party shall issue
a written order specifying such Change (a "Change Order"). UTS and MCI shall
negotiate in good faith with respect to each Change Order (including without
limitation completion dates and additional or reduced costs resulting from such
Change Order), and, upon agreeing to the Change Order, amend this Agreement to
reflect such agreed upon Change Order.

                  3.2 If the Change Order is rejected by the receiving party,
both UTS and MCI shall negotiate in good faith for a period of no longer than
[***] immediately following the determining party's receipt of the written
rejection of the Change Order, with respect to the proposed Change Order
(including without limitation completion dates and additional or reduced costs
resulting from such Change Order). If the parties fail to reach agreement on the
Change Order, the disagreement shall be submitted to an executive panel
consisting of 2 senior executives of MCI, and 2 senior executives of UTS for
further negotiation, and, upon agreeing to the Change Order, UTS and MCI shall
amend this Agreement to reflect such agreed upon Change Order.

                  3.3 If the disagreement cannot be resolved by the executive
panel within [***] of the date of the written rejection of the proposed Change
Order, MCI determines whether the relevant Change Order ("Disputed Change
Order") should be made or not, and UTS shall provide the Development Services
according to such MCI's determination. UTS shall, as applicable, (a) notify MCI
in writing of any additional or reduced costs and revised completion dates for
the Development 


                                      -3-


Services and/or other issues it believes in good faith should reasonably be 
reflected in the Disputed Change Order; and (b) maintain itemized records of 
the times, labor, expense and other cots factors it spends relating to the 
Development Services performed under the Disputed Change Order. The parties 
shall continue good faith negotiation with respect to appropriate additional 
or reduced costs under the Disputed Change Order. If no agreement is reached 
between the parties hereto with respect to the Disputed Change Order within 
[***] after the date on which the Disputed Change Order is issued, the 
parties may resort to the dispute resolution mechanism set forth in Section 
17 herein.

         4.       TESTING AND ACCEPTANCE

                  4.1 UTS shall deliver to MCI an initial proposal of the
acceptance criteria of each of the Deliverables at least [***] prior to the

acceptance criteria within [***] of receipt of UTS' initial acceptance criteria
proposal. MCI may, upon negotiation in good faith with UTS, define acceptance
criteria ("Acceptance Criteria").

                  4.2 UTS shall deliver to MCI each of the Deliverables in
accordance with the Milestone Schedule and Development Plan, such that testing
and acceptance by MCI may be completed on a timely basis consistent with the
Milestone Schedule and Development Plan.

                  4.3 MCI shall test and evaluate each Deliverable delivered by
UTS in accordance with the applicable Acceptance Criteria, and issue to UTS a
notice of acceptance or rejection of such Deliverable within [***] after MCI's
receipt of such Deliverable.

                  4.4 If MCI determines that any Deliverable (or any portion
thereof) fails to satisfy the applicable Acceptance Criteria (a
"Non-Conformity"), MCI shall provide UTS with a written notice of such
Non-Conformity (a "Non-Conformity Notice"), identifying such Non-Conformity in
detail reasonably sufficient to enable UTS to duplicate or observe such
Non-Conformity.

                  4.5 Upon receiving a Non-Conformity Notice, UTS shall provide
to MCI a report describing the cause of such Non-Conformity and the correction
thereto within [***] after the date of receipt of the Non-Conformity Notice, and
shall correct the Non-Conformity and deliver the corrected Deliverable to MCI
within [***] after the date of receipt of the Non-Conformity Notice. Such notice
shall be acceptable in either written or e-mail form.

                  4.6 If, after receipt of a corrected Deliverable under Section
4.5, MCI determines that the Non-Conformity reported by MCI in the applicable
Non-Conformity Notice has not been corrected, or discovers other
Non-Conformities in such Deliverable, MCI may, at its option:

                           (a)      reject such corrected Deliverables, and 
repeat the procedure described in Sections 4.3, 4.4, 4.5 and 4.6 of this 
Agreement, in which case UTS will deliver a revised Deliverable to MCI for 
evaluation under Section 4.3 no later than [***]after the date of receipt of 
such rejection by UTS; or

                           (b)      correct such Non-Conformity itself or 
have its designee correct such Non-Conformity, charging to UTS or deducting 
from any payment due to the UTS an amount equal to the reasonable cost of 
correcting such Non-Conformity.

Affiliate shall provide the UTS notice of any such Claim promptly after MCI
and/or its Affiliate shall receive notice or obtain knowledge thereof, and
provide to UTS such reasonably available and disclosable information and
assistance as is reasonably requested by UTS in connection with such Claim. Upon
MCI's request, UTS agrees to inform MCI of the status of any such Claim, and to
consult with MCI before agreeing to any settlement of any such Claim. In no
event shall MCI agree to any settlement or compromise of a Claim involving any
remedy other than the payment of monetary damages without obtaining the prior
written approval of MCI. MCI shall have the right to assume or participate in
the defense of a Claim, at any time, at its own expense. If an injunction is
issued in such action or agreed in the settlement barring the use by MCI or any
Affiliate of any allegedly infringing Deliverable, or in MCI's opinion, any
Deliverable is likely to become the subject of a claim of infringement, MCI
shall at its option and expense either (i) procure for MCI and its Affiliates
the right to continue to use such Deliverable; and/or (ii) replace or modify
such
