                                   APPENDIX F

                REJECTED MATERIALS ADMINISTRATION (RMA) PROCEDURE

INTRODUCTION

1.    This procedure outlined the handling of Wafers that the Solland Solar
      regards not being in conformity with the Specifications as given in
      Appendix A. The Procedure is valid for all Wafers produced by Supplier's
      manufacturing or subcontractor facility in Xinyu City, Jiangxi Province,
      P.R. China

2.    Handling of non-conformances

      If the Solland Solar is of the opinion that the whole or part of the
      Shipment contains Wafers or other items which are not in conformity with
      the agreed Specifications (including packing and labeling), following
      steps shall be taken:

      -     The Solland Solar shall notify the Supplier by fax or by e-mail that
            there is an upcoming claim related to a non-conformance.

      -     Supplier shall upon such notification provide a RMA number to be
            used as identification when Wafers are returned from the Solland
            Solar to the Supplier.

      -     As soon as the RMA Wafers and the RMA report (which describes the
            non conformity) are received by Supplier, it will be checked for by
            the Supplier.

The outcome of this inspection may fall into several categories, including but
not limited to:

(a)   The Wafers that meet the agreed Specification will be returned to the
      Solland Solar.

(b)   Wafers that do not meet the Specification shall be replaced by the
      Supplier and the replacement of the Wafers shall be forwarded as part of
      the next shipment.

(c)   Should there after above inspection still be Wafers where the Supplier and
      Solland Solar cannot agree on classification, handling and possible
      compensation, such cases shall be subject of further discussion in
      dedicated meetings.

                                   APPENDIX F

                REJECTED MATERIALS ADMINISTRATION (RMA) PROCEDURE

INTRODUCTION

1. This procedure outlined the handling of Wafers that the Solland Solar regards
   not being in conformity with the Specifications as given in Appendix A. The
   Procedure is valid for all Wafers produced by Supplier's manufacturing or
   subcontractor facility in Xinyu City, Jiangxi Province, P.R. China.

2. Handling of non-conformances

   If the Solland Solar is of the opinion that the whole or part of the Shipment
   contains Wafers or other items which are not in conformity with the agreed
   Specifications (including packing and labeling), following steps shall be
   taken:

   - The Solland Solar shall notify the Supplier by fax or by e-mail that there
     is an upcoming claim related to a non-conformance.
   - Supplier shall upon such notification provide a RMA number to be used as
     identification when Wafers are returned from the Solland Solar to the
     Supplier.
   - As soon as the RMA Wafers and the RMA report (which describes the non
     conformity) are received by Supplier, it will be checked for by the
     Supplier.

The outcome of this inspection may fall into several categories, including but
not limited to:

a) The Wafers that meet the agreed Specification will be returned to the Solland
   Solar.
b) Wafers that do not meet the Specifications shall be replaced by the Supplier
   and the replacement of the Wafers shall be forwarded as part of the next
   shipment.
c) Should there after above inspection still be Wafers where the Supplier and
   Solland Solar cannot agree on classification, handing and possible
   compensation, such cases shall be subject of further discussion in dedicated
   meetings.

                                      APPENDIX D

                             QUANTITIES AND DELIVERY SCHEDULE

The following specific terms and conditions apply to the quantities of Wafers
to be supplied to Solland Solar by LDK under this Agreement:

For the purpose of interpreting this Appendix and all documents relating
thereto, the following definitions are used. Words incorporating the singular
will also include the plural and vice versa, where the context so requires.

'MAXIMUM ANNUAL QUANTITY': means the maximum number of Wafers as specified
below that Supplier can be obliged to supply to Solland Solar in any given year.

'MINIMUM ANNUAL QUANTITIES': means the minimum number of Wafers as specified
below to be purchased by Solland Solar in any given year.

'AGREED ANNUAL QUANTITIES': means the agreed number of Wafers to be purchased by
Solland and to be supplied by LDK in a specific calendar year under this
Agreement, being a number of Wafers within the range from the Minimum Annual
Quantities to the Maximum Annual Quantities, which number is determined and
communicated by Solland Solar ultimately before November 1st in the foregoing
year.


1. MAXIMUM ANNUAL QUANTITIES
The Maximum Annual Quantities in a given calendar year starting in 2008 are
calculated as follows:
33 1/3% (thirty three one third per cent) of the actual total solar cells'
production volume of Solland Solar in such given calendar year.

Solland Solar's yearly solar cells' production capacity (end of the year
situation) is currently expected to develop as follows:
2007: 110 MWp*
2008: 210 MWp*
2009: 310 MWp*
2010: 460 MWp*
(* volumes calculated on basis of 20 MWp = 5,460,000 Pcs in 2007)

Solland Solar's yearly solar cells' production volume is currently expected to
develop as follows:
2008: 150 MWp*
2009: 275 MWp*
2010: 400 MWp*
(* volumes calculated on basis of 20 MWp = 5,460,000 Pcs in 2007)

2. MINIMUM ANNUAL QUANTITIES

The Minimum Annual Quantities in a given calendar year starting in 2008 are
calculated as follows:
25% (twenty five per cent) of the actual total solar cells' production volume
of Solland Solar in such given calendar year.

For the year 2008 up to 2010 the following Annual Quantities apply:
