          determine which portions of the Leased Premises shall be classified as
          office or factory space, warehouse space and/or open space. The
          classification made by the LESSOR shall be binding and conclusive on
          the LESSEE.

     Section 2. TERM OF THE LEASE: RENEWAL AND PRETERMINATION

     2.01 This Contract of Lease shall be for a period of ten (10) years

between the LESSOR or its successor-in-interest and the LESSEE and shall be

of the Leased Premises at the time of renewal of the lease. In

     3.04 In the case of non-payment by the LESSEE of the monthly rental as and
when due, the LESSEE shall pay to the LESSOR or its successor-in-interest a
penalty at the rate of three percent (3%) per month on the unpaid amount. The
penalty charged shall accrue from the date of non-payment to, but not including,
the date when the defaulted amount is paid in full. The payment of the penalty
shall be without prejudice to the exercise by the LESSOR or its
successor-in-interest of its right under Section 12 hereof.

     Section 4. CARE AND USE OF LEASED PREMISES

     4.01 The LESSEE shall take care of the Leased Premises with the diligence
of a good father of a family. The LESSEE shall be responsible, at its own
expense, for keeping the Leased Premises in good condition so that upon the

Premises in good order and in the same condition as they were actually found at
the beginning of the lease.

the LESSEE.

highly inflammable or explosive materials nor install therein any apparatus,
machinery or equipment which may expose the Leased Premises to fire or increase
the fire hazard thereof or change the insurance rates applicable thereto; nor
shall the LESSEE introduce, keep or store in the Leased Premises any other
article which the LESSOR or its successor-in-interest may reasonably prohibit.
The LESSEE shall not carry on or permit upon the Leased Premises any trade or
occupation or suffer to be done any other thing which may expose the Leased
Premises to fire hazard or render any increase or extra premium payable for
insurance of the building against fire, earthquake and the like, or which may
make void or voidable the whole or part of any policy of such insurance.

     4.03 The LESSEE shall use the point along Marinar Drive for ingress to and
egress from the Leased Premises. The LESSOR or its successor-in-interest,
however, agrees to allow ingress to and egress from the Leased Premises through
other locations in emergency situations as advised by the LESSEE.

     The LESSEE shall allow the LESSOR or its representatives or assigns ingress
and egress along the existing passageway which will now form part of the

by the LESSEE or its duly authorized representative by reason of its violation
or non-observance of or non-compliance with any of the laws, ordinances and
governmental rules and regulations.

     Section 7. INSPECTION OF LEASED PREMISES

          The LESSOR or its duly authorized representatives, at any time during
business hours, shall have the right to enter the Leased Premises for the
purpose of inspecting the condition thereof.

     8.01 During the effectivity of this Contract, the LESSEE shall fully and
promptly pay all expenses for water, electricity, telephone, or garbage disposal
and other public utility services used and/or consumed by the LESSEE in the
Leased Premises.

     8.02 The LESSOR warrants that during the term of the Lease, the LESSEE
shall have access for a fee to the water supply from the LESSOR's water pump
located within the DMC II Compound, the location of which is more particularly
identified in Annex "A" hereto.

     Section 9. IMPROVEMENTS : ALTERATIONS

     9.01 The LESSEE may make any alteration, addition or improvements on the
Leased Premises; Provided that such alternation, addition or improvements shall
not diminish the value of the Leased Premises nor adversely affect the

on the Leased Premises shall be subject to the prior written consent of the
LESSOR or its successor-in-interest, which consent must be given by the LESSOR
or its successor-in-interest within forty five (45) days from the date of
receipt of the LESSEE's request. If the LESSOR or its successor-in-interest
fails to communicate its decision on the LESSEE's request within said period,
the LESSOR or its successor-in-interest shall be deemed to have approved the
LESSEE's request. Such alterations, additions or improvements on the Leased
Premises shall become the property of the LESSOR or its successor-in-interest
upon termination of the lease; Provided, however, that movables, machineries,
equipment and accessories installed on the Leased Premises shall remain
properties of the LESSEE and shall, upon expiration of the lease, be removed by
the LESSEE from the Leased Premises; Provided that should the removal cause
damage or injury to the Leased Premises, the LESSEE shall at its own expense
promptly repair and restore the Leased Premises to a condition as good as or
better than that which existed prior to such damage or injury. Without in any
way affecting the LESSEE's obligation to repair the damage or injury, the LESSEE
shall deposit with the LESSOR or its successor-in-interest on or before the date
of removal of the movables and the

          LESSOR or its successor-in-interest sends written notice to the LESSEE
          with respect thereto,

(then and in any such event), the LESSOR or its successor-in-interest may, by

return and surrender the Leased Premises to the LESSOR or its authorized
representatives free from any liens or encumbrances, in as good a condition as

other than such additions or improvements which pertain to the LESSOR or its
successor-in-interest in accordance with the provisions of Section 9 hereof.

     Section 13. ARBITRATION

     All disputes, questions or differences (except determination of rental fee
during the Renewal Period and/or failure of the LESSEE to pay rentals to the
LESSOR or its successor-in-interest) which may at any time arise between the

parties and from which there will be no appeal, subject to the provisions on
vacating, modifying or correcting an award under the Philippine Arbitration Law
(Republic Act No. 878). Except for failure of the LESSEE to pay rental or the
occurrence of other events of default, neither party shall be deemed to be in
default or breach under this Contract if a bonafide dispute with respect to the
existence of a default or breach has arisen between the parties and such dispute
has been submitted by either party to arbitration.

     Section 14. NON-WAIVER

     The failure of the LESSOR or its successor-in-interest to insist upon a
strict performance of any of the terms, conditions and covenants hereof shall
not be deemed a relinquishment or waiver of any rights or remedy that a LESSOR
or its successor-in-interest may have; nor shall it be construed as a waiver of
any subsequent breach or default of the terms, conditions and covenants hereof,
which terms and conditions and covenants shall continue to be in full force and
effect. No waiver by the LESSOR or its successor-in-interest of any of its
rights under this Contract shall be deemed to have been made unless expressed in
writing and signed by the LESSOR or its successor-in-interest.
