    The
quantity of the modules processed under this contract is subject to a +/-30%
change.

    

    2.
Quality requirements:

    

    2.1
Physical parameters of cells offered by Party A: See Annex 1—Party A's product
specification.

    2.2 Party
B shall conduct production according to the workmanship and quality standard
required by Party A, and ensure that the qualification of the modules delivered
by it will comply with the TUV certification standard, and their quality is not
lower than the quality of the same type of products.

    2.3 In
case of any changes in raw material and workmanship, Party B shall notify Party
A in advance and obtain Party A's confirmation. The aforesaid changes shall not
cause any degradation of performance of the modules.

    2.4 Party
B shall promise to provide quality assurance for the modules processed under
this contract. See Annex 2—Limited quality guarantee of modules.

    2.4.1 The
tolerance range of the power of any single module shall be within ±3%; the
average power of the whole batch of modules shall not be less than 170W; in case
that the power of any module fails to reach the agreed standard for reason not
attributable to Party B's workmanship or auxiliary material, Party A shall
assume the responsibility by itself.

    2.4.2
Party B shall provide quality assurance with respect to the raw materials
(except for the cells) and workmanship within five years from the date of Party
A's acceptance. If there is any quality problem occurring to the modules during
this period, Party B shall unconditionally repair or replace the modules and
bear the corresponding losses.

    2.4.3
Party B promises that the minimum peak value of modules shall not be lower than
90% of the nominal value within 10 years, and not lower than 80% within 25
years. If the attenuated power of modules during this period exceeds this
standard, Party B shall unconditionally repair or replace the modules and bear
the corresponding losses. Any losses relating to quality problems attributable
to cells shall be born by Party A.

    2.5 Party
B shall cover the expenses incurred in the process of repair and replacement of
modules.

    2.6
Junction box: MC4; the length of conductor shall not be less than 900mm, and the
frame thickness is 50mm.

    2.7 The
brand is CEEG. Each module shall have a serial number and a label marked with
the brand name and specific parameters of modules, etc. Chinese characters shall
not be included in any label.

    2.8 Each
module shall be labeled to indicate that the cells are manufactured by China
Sunergy. Party A shall provide such labels to Party B and has the right to
cancel this label.

    2.9 Loss
of cells: for purpose of performing this contract, Party A shall bear 1% of the
losses of cells in the transportation and packaging process, and Party B shall
bear the losses of excess part incurred in the normal production. In case that
Party B uses more than 3,054,240 cells to manufacture the 42,000 modules
hereunder, and such excess use of cells is not attributable to the quality of
cells, Party B shall purchase the excess number of cells from Party A at its own
cost. If any modules manufactured hereunder do not meet the delivery standard
due to raw materials or workmanship reason of Party B, Party B shall be
responsible to handle such modules and bear the losses incurred by Party A due
such delayed delivery.

    

    3.
Delivery:

    3.1 Place
of delivery: Party B's factory.

    3.2 Time
of delivery: Party A shall deliver the cells to Party B in batches in advance,
and the modules must be delivered within the time stipulated in Annex 3—Delivery
requirements for modules. Party A shall assume the responsibility of any delayed
delivery due to Party A's delayed delivery of cells. In case of adjustment of
the time of delivery, it must be determined by both parties through negotiation
in the form of e-mail notification.

    3.3 In
case of delayed delivery, Party B shall bear the liquidated damages of 0.1% of
the processing charge for the modules delayed, but the total amount of
liquidated damages shall not exceed 5% of the contract amount.

    

    4.
Packaging:

    Party B
shall provide the external packaging of modules and pack such modules in pallets
depending on the module types. All the external packaging shall meet the
requirement of long-distance sea transportation. The cartons shall be marked
with product name, specification, serial number, gross weight, net weight, size
and shipping mark, etc., and the contents shall be clearly visible (no Chinese
characters). If there is a special requirement in any order, Party B shall
package according to the requirement of Party A's Production
Order.

    6.
Payment:

    After the
execution of this contract, Party B shall deliver the products on time. Party B
shall send the VAT invoice to Party A within five days after Party A or Party
A's designated company finishes the acceptance and confirms the products, and
then Party A shall pay the processing fee to Party B within 15 days after
receiving such invoice. If Party A delays to make a payment, it shall bear the
liquidated damages of 0.1% of the delayed amount per day, and the total amount
of liquidated damages shall not exceed 5% of the contract amount.
