aerodyn’s employees to get an idea of the damage. The aim is to discern design defects that may become known as early as possible and remedy the same. If such an information is not given or if the same is culpably delayed, any liability on the
part of aerodyn shall be excluded. 

 Art. 10 Restrictions on Liability for aerodyn 

 

	10.1	aerodyn shall not be liable for any damage suffered by third parties, for example the customers of the Licensee, because of the use of the transferred Contractual
Know-how or the delivered documents and papers, for whatever reason. 

  

	10.2	The Licensee shall indemnify aerodyn against all claims asserted by third parties against aerodyn due to warranty obligations of the Licensee with regard to its
customers or due to statutory liability or product liability. 

 Art. 11 Procedure in the Event of Conflicts of Industrial
Property Rights 
  

	11.1	aerodyn is not aware of any third-party rights with regard to the subject-matter of the Agreement in the Contractual Territory impeding the manufacture or distribution
of the aeroBlade 1.5 which could justify the attack of a third party on the know-how to be transferred. 

  

	11.2	aerodyn assures there is third party right in the Contractual Territory (e.g. patents, utility models) to the subject-matter of the Agreement which have been published
up to 6 month before signature of the contract or which will be published during the duration of the contract. 

  

	11.3	The Articles 11.4 to 11.6 will apply for attacks on the Contractual Know-how from a third party for reasons others then defined in Article 11.1 to 11.2 above.

  

	11.4	Should it come to the knowledge of one of the parties to the Agreement that there is danger of an attack on the Contractual Know-how from a third party or that claims
in this respect are asserted by a third party, the parties shall inform each other thereof and ward off such attacks jointly. aerodyn shall bear all the costs, if the attack happens. 

 

 Page 14 of page 21 

	11.5	In order to defend third-party claims, aerodyn shall be entitled to redesign the aeroBlade 1.5 in such a way that an infringement of industrial property rights does not
exist any more. 11.6 If a conflict of industrial property rights is inevitable and cannot be cleared up, aerodyn shall bear all the liability. 

Art. 12 Remuneration, Royalties 
  

	12.1	The Licensee shall pay the Basic License Fee for two blade lengths of EURO 325,000.00 in accordance with the Payment Schedule in Annex 9. 

 

	12.2	The Basic License Fee for each further blade length of the aeroBlade 1.5 shall be EURO 80,000.00 and shall be paid immediately after receipt of the design documents for
this blade length. 

  

	12.3	In case the Licensee will establish a Joint-Venture or similar partnership, the Licensee shall pay a reduced Basic License Fee to aerodyn. The Licensee shall pay the
same percentage of the Basic License Fee as defined in Article 12.1 and Article 12.3 to aerodyn as the share of the partners are in the Joint-Venture or similar partnership. If, for example, the Licensee holds 60% of the Joint-Venture or
partnership, the Licensee shall pay 40% of the Basic Licence Fee to aerodyn. 

  

	12.4	Furthermore, the Licensee shall pay to aerodyn a Support Fee for the services defined in Art. 2.3 and Annex 3. The Support Fee during the first three years for the
first production facility is fixed at 50,000 EUR for each period of 12 month independently of the number of moulds used and includes three visits of three working days each year. If the customer requests support for additional production facilities
or wants to extend the support beyond the period of 3 years, the Support Fee will be charged per rotor blade mould used in the amount specified below; in this connection, aerodyn assumes that the Licensee will manufacture so many rotor blades that
several rotor blade moulds will be necessary: 

 . 50,000 EUR for each period of 12 months for the first rotor
blade mould in return for the support for series production, and accordingly 
 . 30,000 EUR for each period of 12 months for the
second rotor blade mould, and 
 . 15,000 EUR for each period of 12 months for each further rotor blade mould. 

 

	12.5	The support fee according to Art. 12.4 may be demanded by aerodyn as soon as the first rotor blade is removed from a rotor blade mould. The Licensee undertakes to
notify aerodyn of such point in time without aerodyn being required to ask. The support period for the first rotor blade mould shall begin after a successful Blade Test of the prototype blade. The fees becoming due thereafter for the following 12
months will be charged by aerodyn at the beginning of each 12-month period after notification by the Licensee. 

  

 Page 15 of page 21 

	12.6	The Support Fee for the moulds at each additional production facility is settled in the same way as for the first production facility, that is 50.000 EURO for each
period of 12 months for the first rotor blade mould, 30.000 EURO for each period of 12 month for the second rotor blade mould and 15.000 EURO for each period of 12 month for every additional rotor blade mould in this additional production facility.

  

	12.7	Remunerations for additional services by aerodyn as defined in Article 5.6 will be charged on the basis of aerodyn’s hourly rates according to the time required if
the parties to the Agreement have entered into an additional agreement in this respect beforehand. In 2007 aerodyn’s hourly rates amount to 111 EUR/h and will increase annually by 4% as from January 2008. 

 

	12.8	The Support Fee according to Article 12.4 and 12.6 will increase annually by 4% as from the first time to terminate the contract as defined in Article 17.2.

 Art. 13 Invoicing Procedure 
  

	13.1	aerodyn’s claims for remuneration will become due 30 days after invoicing and sending of the invoice by aerodyn, payable by transfer to the bank account specified
by aerodyn. 

  

	13.2	Invoicing shall be effected on the basis of an invoice according to the specimen enclosed herewith as Annex 5. 

 

	13.3	A right of retention or the right to a set-off shall be excluded. If the Licensee does not pay the agreed remunerations by the agreed date, interest of 8.5% shall be
paid on the respective amount due as from that point in time. 

 Art. 14 Taxes 

 

	14.1	All public levies (taxes, charges, customs duties) imposed in connection with the conclusion of this Agreement or the execution thereof shall be borne by aerodyne in so
far as such levies are imposed to aerodyne either in the Federal Republic of Germany or People’s Republic of China, and the Licensee shall pay all such levies as far as they are imposed to the Licensee. 

 

	14.2	The parties to the Agreement will support each other in the implementation of this rule and give such information as is required in order to be able to make the
necessary statements with regard to authorities. However, they shall not have the right to try to find out confidential company data or inspect the books of the other party.

 Calculated Power Curve

 The power data refers to wind speeds at hub height. The characteristic line of mechanical power has been calculated
assuming stationary flow conditions for an air density of 1.225
kg/m3 at standard atmosphere and dry rotor blades with
aerodynamically smooth profiles. 
 Further, blade pitch angles according to the values shown in the table are assumed. It is pointed out
however that the optimum pitch angle can deviate slightly due to calculation uncertainties and unavoidable manufacturing tolerances. 

Depending on the surface contamination of the blade and the turbulence intensity of the wind the power data can vary by about - 5 % due to physical
reasons. 
 The electrical power data refers to the delivery at the transformer clamps under consideration of own consumption and electrical
transmission losses within the system. Further the listed assumed transmission efficiencies of mechanical components have been taken into account in the calculation of electrical power data. The own consumption of the system (pitch drives, coolers,
tans, pumps, etc.) has been included in the electrical efficiencies. 
 All electrical and mechanical efficiencies are based on an estimate. If
other efficiency factors are used the electrical power data and hence the energy yield will change accordingly. 
 When comparing this data with
a measured power curve according to a generally accepted standard the possible real power deviation resulting from a fault analysis of the measurement and evaluation system has to be considered. Only measurements without rain are to be used and the
mean yaw angle deviation as well as the blade pitch angles are to be recorded.

 Annex 3: 

Scope of work for series production support 

1 Series Production Support 
 General
comments: 
 One aerodyn engineer will regularly visit the production facility of the Customer during the Support Period which is defined in
the contract. During the visits the aerodyn engineer will examine the quality control system and the production process of the aerodyn rotor blades. The purpose of the visit is explicitly not the training of the production staff of the Licensee. The
visits will take place every 4 month during the Support period. The duration of the visits depends on the number of negative moulds used at the production facility as defined in the following: 

 

	 	•	 	 2 working days for one negative blade mould 

  

	 	•	 	 3 working days for two negative blade moulds 

  

	 	•	 	 4 working days for more then two negative blade moulds

 Annex 8: 

Required tools and equipment 

The following lists the major tooling and equipment requirements of a blade manufacturing facility. These tools and equipment represent a minimum
standard, necessary to ensure the final quality of the project and the health and safety requirements of the workers. This list is by no means complete. Numerous additional smaller tools are required and should be considered to successfully produce
a blade – those listed are capital intensive resources. 
 In all cases, tools and facilities should be chosen/developed to meet local
environmental health and safety regulations and ensure the interests of workers are maintained. 
 The list is separated in tools and equipment
which are designed and specified by aerodyn in detail and those for which aerodyn does not give a detailed specification. 
  

	1	Tools and equipment designed and specified by aerodyn 

  

	1.1	Moulds 

 For the manufacture the following
moulds will be required: 
  

	 	-	Blade shell moulds (suction side + pressure side) 

  

	 	-	Spar cap moulds 

  

	 	-	Shear web moulds 

  

	 	-	Bonding flange moulds (LE + TE) 

 All moulds
must be vacuum tight and manufactured to exacting dimension. For these moulds, it is in general required that a positive mould (plug) be manufactured beforehand. 
  

	1.2	Hydraulic turning mechanism 

 In order to
close the mould, a hydraulic turning mechanism is envisaged. This shall be specified in detail as part of the licence package. 
  

	1.3	Heating system (to be specified later) – including temperature monitoring 

All primary and auxiliary moulds must be equipped with an appropriate heating system in order to ensure the cure quality of the component. These systems
shall be specified by aerodyn. Additionally, appropriate temperature monitoring systems must be installed to track the cure at multiple locations on the blade. 
  

 Page 1 of 4 

	2	Tools and equipment without detailed specification by aerodyn 

  

	2.1	Vacuum system 

 All primary (blade shells)
and auxiliary moulds must be appropriately equipped with vacuum systems—which should include pumps, vacuum ports, vacuum monitors etc. 
  

	2.2	Resin mixing machines 

 In order to ensure
a consistent quality of the resin and the final product, resin mixing machines are required with an appropriate capacity. Advice will be given in the selection of such machines. 

 

	2.3	Bonding paste mixing machines 

 In order
to ensure a consistent quality of the bonding paste and the final product, bonding paste mixing machines are required with an appropriate capacity. Advice will be given in the selection of such machines. 

 

	2.4	Positioning tools 

 Additional tools will
be required for the positioning of, in particular, the shear webs. 
  

	2.5	Transportation systems 

 Crane System:

 In order to safely and effectively handle the blade it is necessary for the facility to be equipped with cranes. These must include a
“soft start” feature to ensure that no damage occurs during handling. It is recommended that 2x1 OT cranes are available. 

Prefabricated component transportation systems: 

Consideration should be given to effective transportation of, for example, spar caps. Ideal possibilities include vacuum suction supports mounted on the
crane to ensure minimal damage. 
 Fork lifts: 

Fork lifts should be available to transport the raw materials, etc. These must be gas or electric to avoid the emission of particles which will effect
the lamination process. 
 Additional transportation: 

Consideration should be given to the effective transportation of the finished blades.

	2.6	Drilling/Cutting machine 

 A drilling
machine is required for drilling the blade bolt holes (both tension bolts and cross bolts). This is in general combined with the tool for cutting the blade at the flange interface between blade and pitch bearing. Machine most be capable of matching
exacting tolerances and as such, it is a significant investment. 
  

	2.7	Painting hall 

 A painting hall is
required to ensure a consistent quality and durability in the painting process. These hall is also required to ensure appropriate ventilation during the spray process which involves the release of a high concentration of toxic volatiles and also
heating to 60° to cure the paint unless lower curing temperatures are specified by the supplier of the surface coating. The outlet and handling of the gasses through the ventilation system should be managed in a manner in accordance with workers
and environmental, health and safety requirements. 
 In addition to the hall, airless painting systems are also required to ensure a high
quality of finish. 
  

	2.8	Appropriate production facility 

 It is
required that the licensee has access to an appropriate production facility. An appropriate production facility should have sufficient floor space to provide for: 
  

	 	-	Glass + resin storage 

  

	 	-	Blade moulds including required tooling 

  

	 	-	Blade finishing hall 

  

	 	-	Blade drilling station 

  

	 	-	Glass cutting room 

  

	 	-	External storage of finished blades 

 In
addition, it is critical that the following issues are taken into account: 
  

	 	-	Appropriate ventilation for the blade finishing/sanding area 

  

	 	-	Appropriate room for storage of resin and glass (both used and unused) with sufficient air ventilation and fire containment. 

 

	 	-	Temperature controlled production facility (15°-25°) to ensure close control of resin infusion parameters. This can be restricted simply to the infusion hall,
the maximum temperature for series production can be increased to 30° if special processing requirements are observed. 

  

	 	-	Humidity control according to the resin suppliers specification 

  

 Page 3 of 4 

	2.9	Blade testing mounting frame 

 The
licensee must have access to an appropriate test mounting frame and instrumentation (data loggers, strain gauges, displacement gauges etc) to test the blade. This may or may not be the property of the licensee. 

 

	2.10	Additional 

 A number of extra smaller
tools and equipment will be required throughout the production process. It should be taken into account that additional resources will be required.
