fails to achieve any Phase or Sub-phase on or before the respective Target Date
for such Phase, and the Works have not been completed in the following sixty
(60) calendar days, in case of Phase I, 30 days for Phase H and 15 days for
Subphases III- A and III- B, Lessee shall have the right to give Lessor a
written notice that it intends to complete the portion of Lessor's Work
necessary to achieve such delivery, and if Lessor fails to complete such portion
of Lessor's Work within thirty (30) calendar days after Lessor receives such
notice. Lessee shall have the right to perform such portion of Lessor's Work, at
Lessor's expense. If due to the nature of the works it is impossible for the
Lessor to finish them in thirty (30) days, it win have to begin all necessary
actions in order to finish them, and if it does, it will have an additional
reasonable term to finish to be approved by Lessee. If Lessor has not started
all actions required in order to do so within fifteen (15) days after Lessor
receives such notice, and, in any event, if the Lessor has not completed the
work after the additional reasonable term approved by Lessee, then the Lessee
will be allowed to complete the Lessor's Work, at Lessor's cost and expense.
Lessor will reimburse Lessee for the costs so incurred by Lessee within thirty
(30 days) after Lessee delivers to Lessor all invoices corresponding to such
costs, that have to be invoices with legal and tax effects in Costa Rica, unless
both parties agree that payment is made by means of deduction of the total
amount owed for such costs from the next monthly rent payment thereafter due
under this Lease and, if such rent payment is not enough, by deducting from the
following months, until the complete amount owed and its interests has been
credited to the Lessee. Lessee may only take over Lessor's Work, provided that
Lessee does not exercise its right to terminate the Lease. Once the Lessee has
taken over Lessor's Work, Lessor will no longer be responsible for further or
new delays not attributable to Lessor.

B.    Liquidated Damages.

1.If, for any reason other than Lessee Delays and Force Majeure Lessor fails to
achieve delivery of Phase One on or before the Target Date for delivery of Phase
One, then Lessor shall pay to Lessee liquidated damages equal in amount to the
product of: (i) the number of days between the date that Lessor achieves
delivery of Phase One and the Target Date for delivery of Phase One, multiplied
by (ii)[*******]. Provided, however, that such liquidated damages shall only be
paid by Lessor if the Lessee does not exercise its right to terminate the Lease.
In case Force Majeure delays Lessor's Work for more than six months. Lessee can
exercise its right to terminate the Lease.

Page 5 of 12

--------------------------------------------------------------------------------

Lessee hereby releases Lessor of any liability or payment of liquidated damages
for delays in the delivery of Phase I, provided Lessor delivers Phase III B on
the Target Date of Delivery of Phase IIIB. If Lessor fails to achieve the Final
Date of Delivery of Phase lll-B on or before the respective Target Date for such
Phase, Lessee will be entitled to liquidated damages as compensation in
accordance with Section 2.05 (B)(1).

achieve the Final Date of Delivery of Phase III- B on or before the respective
Target Date for such Phase, Lessor shall pay to Lessee liquidated damages equal
in amount to the product of: (i) the number of days between the Target Date for
such Phase and the actual date that Lessor achieves the Final Date of Delivery
of Phase III- B, multiplied by (ii)[*******], provided however, that such
liquidated damages shall only be paid by Lessor if the Lessee does not exercise
its right to terminate the Lease, and in no event shall Lessee be entitled to
collect more than [*******] for liquidated damages for any day of delay. As an
example, if Lessor compensated Lessee four weeks of delay after the Target Date
of Phase I or Phase III A, then if there is a delay of the same four weeks at
the Final Date of Delivery of Phase III B, then Lessor will not have to
compensate such delay, since it has already been compensated. Liquidated damages
for Phase II will have to be paid only and exclusively, if delay in delivery of
Phase II affects Final Date of Delivery of Phases HI A and HI B on Target Date
for such Final Date of Delivery. As allowed under Article 705 of Costa Rican
Civil Code, the Lessee irrevocably waives its rights to and guarantees and
acknowledges that it will not file any lawsuits or claims to recover additional
amounts from the Lessor originated in damages caused by a failure to deliver the
Premises in a timely manner for causes attributable to the Lessor, its
contractors, agents or employees, unless otherwise stated in this Agreement.
Additionally if, for any reason other than Lessee's Delays and Force Majeure
occurred after execution of this amendment. Lessor fails to achieve the Final
Date of Delivery of Phase lll-B on or before the respective Target Date for such
Phase, Lessee will be entitled to liquidated damages as compensation for the
delays existing as of the date of signature of this Lease Agreement,
attributable to Lessor in the delivery of Phase I and H in the Target Dates
originally established in Exhibit 7, subject to alt other rights and remedies
under the Agreement, and it shall have the right to use the Performance Bond to
charge them.

In case Force Majeure delays Lessor's Work for more than six months. Lessee can
exercise its right to terminate the Lease.

3.At Lessee's election. Lessee shall have the right to deduct any liquidated
damages due from Lessor to Lessee pursuant to this Section 2.05 from the amount
of Rent and other charges due from Lessee to Lessor hereunder.

C.    If Lessor fails to achieve any Phase or Sub-phase on the date (“Outside
Termination Date”) six (6) months after the Target Date for such Phase, Lessee
shall have the right to terminate this Lease by giving written notice to Lessor.
The Outside Termination Date shall be extended by any period of time that Lessor
is delayed in the performance of Lessor's Work by reasons of Force Majeure

Termination Date occur later than the date six (6) months after the Target Date
for such Phase. If Lessee exercises its termination right pursuant to this
Section 2.05C, he will be entitled to the sole compensation indicated as penal
sum pursuant to Section 3.03 (Lessor's Performance Bond}. Lessor hereby waives
all claims against Lessee due to Lessee's Delay which occurred prior to
execution of this Amendment.

D.    Lessor's Performance Bond. The parties confirm and agree that Lessor's
obligations under this Section 2.05 shall be secured by a Performance Bond

Notwithstanding the foregoing, all parties agree and acknowledge that all income
generated as product of the Lease, unless if Lessor is in default, will be
received only by the Lessor, since the Lessor is the direct beneficiary of such
revenues, and therefore, he shall comply with any tax obligation whether
material or formal. The parties also agree that the exclusive purpose of the
Trust Agreement (and its amendments) is to secure the loans set forth therein;
therefore it does not have any kind of lucrative activity, being that the duties
of the Trustee are limited to: (i) hold the trust ownership of the entrusted
assets, and (ii) transfer the entrusted assets, in accordance with the terms and
conditions established in the Trust Agreement. Also, the parties agree that as
long the Lessor keeps acting as the contractor of the overall land (within
which, the leased premises are located), he will assume and undertake all
obligations provided in the Lease Agreement and this amendment.
