             Purchaser in writing Progress Reports to the Purchaser on the
             progress of the Supply of the Part of the System ("Progress
             Report") on a weekly basis, as of the first Business day of the
             then current week of the Programme. Notwithstanding the foregoing,
             the Supplier shall submit the Progress Report with respect to the
             particular Milestone on the date of the completion of the then
             current particular Milestone as such date of completion of the
             Milestone being stipulated in the respective Programme ("Milestone
             Progress Report").

             The Progress Report shall contain a detailed description and
             exhibit of the current state of Supply performed, in comparison
             with the Programme. The Progress report shall be in accordance with
             the Programme. Furthermore it shall provide for the description of

             activity and assistance from the Purchaser and estimate of the time
             delay caused by reported problems/troubles, if any.

             In addition and notwithstanding the foregoing Section the Supplier
             shall in the Milestone Progress Report also report either on (i)
             full completion and finalisation of any and all of the supplies and
             work performances of the then current Milestone as stipulated in
             and in compliance with the respective Programme, or (ii) the
             partial completion and finalisation of any and all of the supplies
             and works performances of then current Milestone as stipulated in
             and in compliance with the respective Programme, or (iii) a failure
             of the completion and finalisation of the then current Milestone.

16.2         The Purchaser shall be entitled to a contractual penalty (which
             shall have the same meaning as "liquidated damages") and any of the
             remedies and/or claims as set out herein, if (i) the Supplier fails
             to complete the Ready for acceptance ("RFA") Milestone, as referred
             to herein within the time limits stipulated for its completion and
             finalisation pursuant to the respective Programme, and the failure
             is attributable and due to the reasons on the Supplier's side
             or (ii) there occurs any other kind of material delay in the
             fulfilment of any of the Supplier's undertakings provided for
             in this Contract,

16.3.        The Supplier shall promptly notify the Purchaser, by the Progress
             Report and/or Milestone Progress Report or by any other means, in
             writing, of the occurrence of the delay, its likely duration and
             its cause(s). If the Supplier neglects to provide this
             notification, the Supplier shall have no right to refer to
             circumstances excluding his liability.

16.4.        The amount of contractual penalty applicable to the failure as
             referred to in Section 16.2 shall be 2,500 EUR per commenced day of
             delay. The contractual penalty shall be computed for each day of
             delay which is the period between the date of Ready for acceptance
             Milestone as stipulated by the applicable Programme and the actual
             date of completion of the Ready for acceptance Milestone.

16.5.        The cumulative amount of all of the claimed and paid contractual
             penalty shall in no case exceed 1,000,000.00 EUR.

16.6.        The Purchaser shall have the right to claim damages in excess of
             the amount of the contractual penalty, however only to the extent
             of the limitation of liability as referred to hereinafter. The
             Purchaser shall be entitled to claim contractual penalty even where
             it has not suffered any damage and regardless whether damage was
             caused or not.

16.7.        If the Supplier fails to (i) complete any Milestone, or (ii)
             Complete any of the Part of the System within and in compliance
             with the Programme, the Purchaser is entitled, by the prior notice,
             including without limitation to withdraw from the Contract, or to
             require the finalisation of the completion as referred to herein
             within an extended additional time, according to the nature of the
             non performance. If the non performance is not fundamental, the
             notice requiring completion shall fix an additional time for
             completion which shall be reasonable.

             In determining whether a failure as referred to hereinabove or to
             perform any of the obligations amounts to a fundamental
             non-performance regard shall be held, in particular, to whether

             (i)     the Supplier while non-performing, knew, or could have
                     reasonably predicted at the time of conclusion of this
                     Contract, taking into account the purpose of the Contract,
                     that the Purchaser would not be interested in performance
                     of the obligation in the event of such non performance,

             (ii)    the non-performance substantially deprives the Purchaser of
                     what it was entitled to expect under the Contract,

             (iii)   the non-performance is intentional or reckless, and/or is
                     attributable or due to the negligent performance of the
                     Supplier's undertakings under this Contract

             (iv)    the non-performance gives the Purchaser reason to believe
                     that it cannot rely on the Supplier's future
                     performance.

             If the Supplier fails to complete within such additional time, and
             this is not due to a cause for which the Purchaser or some other
             person employed by him is responsible, the Purchaser may by further
             notice to the Supplier either:

             (a)  require the Supplier to complete, or

             (b)  immediately withdraw from the Contract.

             The Purchaser shall give credit for the value of any part of the
             Supply which shall not be repatriated to the Supplier. Decision on
             what part of the Supply shall remain in the possession of the
             Purchaser shall remain fully in the discretion of the Purchaser.

             other contractual arrangements in connection with the
             implementation of the variation. As soon as possible but not later
             than 5 Business days after having received such Variation Request,
             the Supplier shall submit to the Purchaser:

             (a)  the Supplier's proposals for a description of variation in the
                  Supply of the System to be performed and a Programme for its
                  execution, and

             (b)  the Supplier's proposals for any necessary modifications to
                  the Programme according to Section 11 or to any of the
                  Supplier's obligations under the Contract, and

             refuse the conditions for such Variation Order submitted by the
             Supplier. If the parties agree to vary the Supply of the System or
             any Part thereof, the Purchaser shall issue a Variation Order
             clearly identifying agreed conditions.

             The Supplier shall not refuse to implement any variations based
             upon the Variation Request without material justifiable reason. In

             justifiable reason for refusing to implement a Variation Request,
             if he has a justified reason for believing that the implementation
             of the variation would jeopardise the successful passing the
             Acceptance Tests or PPS Acceptance Tests, as applicable or if the
             resources required to implement the variation are not at the
             Supplier's free disposal or could not be obtained without incurring
             unreasonable expenses, or if it would adversely affect the
             Supplier's intellectual property. The Purchaser may refuse any
             Variation Request presented by the Supplier without giving any
             reason.

20.3.        If the Parties fail to come to an agreement regarding the
             consequences of this Variation for the Total Price, the Purchaser
             shall, provided that the procedure under Section 35.7.3.  is met,
             pay a price, which is increased or reduced, taking into account
             the difference in the scope of the necessary activities and
             reasonable expenses related to the changed execution of the Supply
             of the System.  The price should be reasonable and in compliance
             with the current Price Table as specified in Annex 13, if
             applicable and shall be quoted DDP Bratislava (INCOTERMS 2000).

26.2.        The Party shall not be liable for and shall not indemnify the other
             Party when such breach was caused by any obstacle which arose

                  immediately upon discovery of any unauthorised use or
                  disclosure of Confidential Information, or any other breach
                  of this Agreement by the Receiving Party, and will co-operate
                  with the Disclosing Party in every reasonable way to help the
                  Disclosing Party regain possession of the Confidential
                  Information and prevent its further unauthorised use.

             (b)  The Receiving Party shall return all originals, copies,
                  reproductions and summaries of Confidential Information
                  (prepared by or on behalf of the Disclosing Party) at the
                  Disclosing Party's request or after the termination of the
                  Contract. All documents, memoranda, notes and other writings

                  therefore, each shall be entitled, in addition to all other
                  available remedies, and without waiver of available defences,

                  by a court of competent jurisdiction, to prevent a breach of
                  this Contract and to secure its enforcement.

37.4.        By disclosing information to the Receiving Party, the Disclosing
             Party does not grant any express or implied right or license to

             commercial information, including specifications, drawings,
             sketches, models, samples, data, computer programs, software,

             513/1991 Coll. as amended).

37.6.        None of the provisions of this Confidentiality Treatment Section
             shall apply to any of entity belonging to the T-Mobile
             International Group.
