SELLER GOODS manufacturerPURCHASER customer who places the order for GOODS KODA POWER a.s.

THE SELLER guarantees the PURCHASER that the GOODS delivered will meet the belowstated parameters:

1 GUARANTEES

1.1 PERFORMANCE RELIABILITY GUARANTEE

The performance reliability is defined by the following formula:

100T

TTK

=

p

fp

D %

where: fT overall duration of forced outages of the delivered equipment within a guarantee period in

hours

pT total number of planned operation hours of the delivered equipment within a guarantee period

The total number of the planned operation hours Tpis equal to the sum of total number of factualoperation hours Toand overall duration of forced outages Tfwithin a guarantee period:

fop TTT += h

The total number of the planned operation hours will always be less or equal to duration of aguarantee period in hours.

The reliability of the delivered equipment will be higher or equal to 99.5 %.

The performance reliability guarantee applies to operation of the delivered equipment within aguarantee period.

The evaluation of the performance reliability will be processed each time when functionality lossof the delivered equipment causes its forced outage.

1.2.1 GUARANTEE CONDITIONS OF PERFORMANCE RELIABILITY

DEFINITION OF FORCED OUTAGE

Beginning of the outage: moment of functionality loss of the delivered equipment caused by its failure

End of the outage: moment of required functionality recovery of the delivered equipment

FOLLOWING OUTAGES WILL NOT BE CONSIDERED AS RELEVANT

outage of the delivered equipment caused by external influences or Force majeure outage of the delivered equipment caused by incorrect attendance (infringement of

operating instructions) extension of repair time of the delivered equipment due to external influences, Act of

Providence or repair of components not included in SELLERS scope, but preventingfrom its required functionality recovery

time of repair of the delivered equipment performed within a reserve shutdown period ofa turboset or its outage caused by a failure of equipment out of SELLERS scope.However, if a request to starting-up the turboset is made and the repair has not beenfinished yet, the time from the request to repair completion and subsequent requiredfunctionality recovery of the delivered equipment will be taken into account.

time of repair that takes place within a scheduled outage of a turboset

PURCHASEROBLIGATIONS operate the delivered equipment in accordance with operating instructions PURCHASER is obliged to file available records about equipment operation within a

guarantee period SELLERS authorized personnel will be granted access to the delivered equipment and

will have at disposal available operation records and information PURCHASER will inform the SELLER about failures of the delivered equipment If a repair is performed by the PURCHASER, the repair will start in the shortest possible

time since failure announcement. The repair will only be performed by personnel withcorresponding qualifications.

2 GUARANTEE TEST CONDITIONSThe stated guaranteed values are meant without tolerance limits. For the evaluation of theguaranteed values that are to be proved by the guarantee measurements, only tolerance givenby measurement uncertainty will be applied.

The operation during the guarantee measurement shall be adjusted in accordance with theReference heat balance diagram and conditions according to the guarantee measurementproject.

If the conditions differ from the defined ones, the resultant values measured will be correctedaccording to correction curves.The resultant values can also be corrected according to other operating conditions that possiblyoccurred and that differ from the calculated ones provided it is discussed and approved by bothcontracting parties.

The guarantee measurement will be performed in accordance with the standard for steamturbine measurement IEC 953-2 . According to this standard, the measurement tolerance willbe determined as well.

For evaluation, water and water steam tables for industrial purposes IAPWS-IF 97 will be used.

The guarantee measurements will start by drawing up an initial report about measurementconditions and methods and its evaluation and will conclude by drawing up a final report aboutthe tests performed.
