1. 1 GUIDELINES TO DEVELOP A CASE STUDY

2. 2 CASE STUDIES OBJECTIVE This stage is one of the most important ones inside the process of negotiation and penetration in one Mine or Mining Group. It is also the most effective way of differentiating ourselves from the competitors by means of our NCH Lubrication – Partners based on Trust. A case study documents real savings and it measures the energy consumption, the temperature of operation, the line pressure, the system wear-out in the selected equipment before and after a system purge takes place, as well as the correct monitoring when adding high performance lubricants. These case studies should totally involve the 4 key points of Top Down Selling: 1. Reduction of dead times 2. Reduction of part replacement 3. Reduction of lubricant consumption 4. Increase in productivity and productiveness of equipment However; to be successful at this step, the following guidelines on getting information must be followed word for word: reading of indicators, correct application and follow-up of tests at the right time; otherwise, the case studies will not have any impact.

3. 3 Case Study Step 1 – Getting Information Selection of equipment or machinery for the Case Study After a successful presentation addressed to the corporate sector with the CEO or superintendent or area chiefs, you must certainly have several case studies: 1. Define together with the decision maker (CEO or superintendent) which will be the most important and outstanding case studies that you must carry out. Preferably, to perform better monitoring, just commit yourself to no more than 3 case studies at the same time in the same mine. 2. Clearly identify on field the equipment, pieces or machinery where you will apply the case study and obtain the correct and complete information (follow all recommendations given in annex 1) 3. After you have this information, you can make a professional quotation for your first case studies (see annex 2)

4. 4 CASE STUDY Getting Upfront Information Objective: 1.Get 100% of the information stated in the chart. 2. Note down the names of everybody involved in the process. 3. Always carry your temperature gun and digital ammeter to verify the information. Do not falsify data as they would alter the case. 4.Verify the re-lubrication times and the exact quantities as well as the current products full name 5. The costs are indispensable for a good case study ANNEX 1 – The real form is annexed in Excel and it is ready to be printed. You should complete it 100%

5. 5 Case Study Step 2 – Quote or Purchase Order Quotation and/or Getting a Purchase Order to run Case Study As you already have the upfront information, that will help us quote in a professional way and get the purchase order, our benefits should be highlighted. 1. The first section of the quotation must include the clients data, when the information was obtained and the background, that is: equipment or component, what do they currently use?, What problems were identified?, the amount of initial load, re-lubrication times, amount of product in re-lubrication. 2. The second section of the quotation must include the re-lubrication amounts and times concerning our lubricant (s). In case we use Bearing Purge or System Purge or Diesel Shield, specify the exact amount needed for pre-treatments. 3. The third section must include attachments with the qualities of each product to be used in the Case Study. 4. The quotation should highlight that NCH will be responsible for all expenses incurred in running the case study and that they will only be in charge of the product. Specify in complete containers in accordance with our packs and the total value of the Case Study. 5. Always attach the pre-authorized MSDS of each product.

7. 7 Case Study Step 3 – Implementation On-Field Implementation of Case Study As you already have your purchase orders, you must be ready to perform the Case Study in the Mine. You should have the following material and information ready : 1. Request products in the agreed amounts from NCH warehouse. 2. Make an appointment in order to fix the date when you will visit them to run the Case Study (do not leave weeks or you will lose impact) 3. If possible and if it is not a big quantity, you can bring the products to the mine because the faster, the better. 4. Remember to bring several printed sheets of the form called Data for Case Study. One for each equipment (annex 3) 5. Bring your temperature gun, digital ammeter, the agreed products, printed safety sheets, your safety equipment as needed for the application, clean grease guns ( 1 for grease and for bearing p.)

8. 8 Case Study Step 3 – Implementation On-field Implementation of Case Study 6. Do not forget any material aforementioned, remember that we are advisors and as such, we need to have everything sorted out and ready in advance. One failure will make us look like another salesperson in the eyes of the client. 7. Apply the product and always remember to take notes before, during and after the application process (follow the recommendations on how to use each product) 8. The forms will contain all the information that you need to gather, do not include other data, do not give information on separate sheets. Never take notes without your forms. 9. These forms must be signed by the personnel in charge of the test on behalf of the mine. This will give more credibility to the information. 10. You will find one form for each type of application (grease, oils or sprays)

9. 9 Case Study Step 3 – Filling in the Form Main Data The Form has several items that you must fill in for each equipment that you will deal with in the Case Study Always remember to request signatures from the person in charge of the test in the mine, and your signature in order to formalize the authenticity of the data.
