08/987 PRESENTATION OVERVIEW BACKGROUND ARIAL EMISSION MANAGEMENT ACHIEVEMENTS Air Quality Program Emission Reduction Process Solvent Recovery Process (Adsorption, Desorption, Purification)

11/998 Imation Camarillo’s Air Quality Program Relies upon Advanced Solvent Recovery Technologies... Impact Reduction at Source Solvent Recovery Unit (SRU) requires 50% less energy than traditional systems, thereby reducing the demand for electricity & natural gas Reclaim - Reuse - Recycle SRU recovers over 99% of all air-borne solvents for reuse in the manufacturing process, thereby reducing air emissions Use of Best Available Technology Specifically designed Rekusorb system ( 1993) Fourier Transform InfraRed Spectrometry Continuous Emissions Monitoring System (FTIR CEMS) (1996) AIR QUALITY PROGRAM

08/9813 OVERVIEW BACKGROUND ARIAL EMISSION MANAGEMENT ACHIEVEMENTS Ventura County Clean Air Fund Public Recognition Proposed Project XL Site

11/9914 Considerable Emission Reductions Resulted in the Ventura County Clean Air Fund... VENTURA COUNTY CLEAN AIR FUND Its history and purpose in a nutshell: In 1989 and 1990, the Camarillo facility cut its emissions from 350 tons per year (tpy) to <200 tpy. (Note: 21 tpy in 1993) These voluntary emission reductions were ‘banked’ as ‘Emission Reduction Credits’ (ERC). In 1991, Camarillo facility sold 78 of its banked ERCs for $1.5 million dollar to neighbouring Proctor & Gamble. The money was used to establish the Ventura County Clean Air Fund, which supports air quality programs and community environmental projects throughout Ventura county.

11/9915 …and Various Environmental Awards PUBLIC RECOGNITION Between July 1996 and 1998 alone, Imation Camarillo’s environmental efforts have been recognized with numerous awards: Waste Watch Award , 1997 & 1996 Gold Award for Continued Excellence in Waste Reduction Programs Waste Reduction Award Program Award Cal. EPA, Integrated Waste Management Board Public Service Recognition Plaque Rio Del Valle Middle School Recognition in Environmental Leadership California Regional Water Quality Control Board Imation Camarillo Environmental Awards Gold Award for Continued Excellence in Waste Reduction Programs

11/9916 Technological Advances Opened Possibilities for “eXellence and Leadership” Project PROPOSED PROJECT XL SITE Project XL : Inaugurated in March 1995 by EPA and Presidency Encourages environmental stewardship and innovation Pilot projects are granted regulatory streamlining as incentive Imation’s Project XL Covenant (1996) Individual and total Hazardous Air Pollution (HAP) cap Plant-wide applicability limit for criteria air pollutants State-of-the-art FTIR CEMS installment for monitoring Streamlined environmental management and reporting procedures (ISO like EMS)
