3. Column Plan ■ How it works ■ Why sell it? ■ What can go wrong Teledyne Isco Confidential 3

4. How the Column Plan Works ■ When Rf is connected to a network when internet connection ■ Rf sends daily column usage data to website – www.mycombiflash.comwww.mycombiflash.com ■ When a box of columns is used – a replacement order is generated ■ Software looks at daily usage versus estimated ship time and might generate an order for additional boxes ■ Software also looks at daily usage for other column sizes on plan for short term shortages and attempts to consolidate shipments Teledyne Isco Confidential 4

5. How Column Plan Works -2 ■ When Rf is not on a network ■ Rf records column usage - once box is used a code is generated and displayed on screen ■ User either copies down the code or copies the code to a thumb drive ■ Code is entered on the www.mycombiflash.com websitewww.mycombiflash.com ■ Replacement order is generated and a replacement box is shipped Teledyne Isco Confidential 5

6. How to Get Started ■ The column plan all starts with a quote ■ At the time of quote the plan worksheet needs to be included with the request ■ The column sizes the plan covers ■ Contact Name ■ Lab address where columns are to be shipped (Not central receiving) ■ No more information is needed when the order is placed ■ When instrument is ready to be installed we need two days notice ■ During those two days, we review worksheet ■ Discuss any changes the user might want ■ Go over what is needed at install Teledyne Isco Confidential 6

7. How to Get Started - 2 ■ On day of install ■ First order of business is to call with MAC address and Serial Number ■ Account is then added to database and is ready for testing ■ Test connection ■ Plan must be in database ■ If any errors – review and correct while onsite Teledyne Isco Confidential 7

10. Why Sell a Column Plan ■ Fixes the customer costs for the year – Tisco assumes the financial risk ■ One time sale ■ University may not have to pay an internal markup on consumables ■ Decreases the opportunity for competitors to compete ■ Customer has consistent stock on hands without having to carry excessive inventory ■ Columns supplied on actual usage – no odd sizes needed ■ Customer does not have to choose column sizes and mix quantities at time of order ■ Customer does not have to place additional PO every time they need additional columns ■ Columns automatically shipped before stock is depleted ■ Column mix can be changed when needs change ■ Should result in lower discount percentages for Tisco Teledyne Isco Confidential 10
