1. The Chemical Engineer of the Future in the Oil and Petrochemical Industry Michael J. Dolan May 7, 2004 Michael J. Dolan May 7, 2004 This presentation includes forward-looking statements. Actual future conditions (including economic conditions, energy demand, and energy supply) could differ materially due to changes in technology, the development of new supply sources, political events, demographic changes, and other factors discussed herein (and in Item 1 of ExxonMobil’s latest report on Form 10-K).

2. The Outlook for Energy Energy is critical to economic growth, especially in developing markets Oil and gas will remain the primary sources of energy through 2020 Energy companies face significant challenges to meet world demand Groundbreaking research required to develop portfolio of energy options Energy is critical to economic growth, especially in developing markets Oil and gas will remain the primary sources of energy through 2020 Energy companies face significant challenges to meet world demand Groundbreaking research required to develop portfolio of energy options

6. The Indispensable Chemical Engineers Fuels and petrochemicals will continue to be large employers of ChE’s Industries are mature with moderate growth but technical challenges are important and significant Enhanced technology will demand broader skills from entry level ChE’s and a need for continuous learning throughout career Fuels and petrochemicals will continue to be large employers of ChE’s Industries are mature with moderate growth but technical challenges are important and significant Enhanced technology will demand broader skills from entry level ChE’s and a need for continuous learning throughout career

7. Manufacturing Plant of Today Plants and equipment are more reliable and predictable – Less trouble shooting and fire fighting – More planning and optimization Computers control all aspects of the manufacturing environment and make routine or repetitive operating decisions that once required engineering assistance – Examples include: online economic optimization, equipment advisories (expert systems), “Safe Park” shutdowns Technicians have been upskilled and perform many of the tasks that chemical engineers performed twenty years ago – Improved training and support as well as expert systems and online optimization Plants and equipment are more reliable and predictable – Less trouble shooting and fire fighting – More planning and optimization Computers control all aspects of the manufacturing environment and make routine or repetitive operating decisions that once required engineering assistance – Examples include: online economic optimization, equipment advisories (expert systems), “Safe Park” shutdowns Technicians have been upskilled and perform many of the tasks that chemical engineers performed twenty years ago – Improved training and support as well as expert systems and online optimization

8. Manufacturing Plant of Tomorrow Competitor in truly global market Ever increasing size, scale, automation will require engineering solutions in all aspects – Materials, equipment, catalyst, process control and optimization Meeting the world’s needs will require technology to squeeze more from every barrel – Cleaner fuels; more functional chemicals Control and optimization of physical properties (temperature, pressure, volume flow) will give way to molecular management Competitor in truly global market Ever increasing size, scale, automation will require engineering solutions in all aspects – Materials, equipment, catalyst, process control and optimization Meeting the world’s needs will require technology to squeeze more from every barrel – Cleaner fuels; more functional chemicals Control and optimization of physical properties (temperature, pressure, volume flow) will give way to molecular management

9. Impact on Chemical Engineers Entry level no longer just design and monitoring – Monitoring, operational advice, optimization largely by technicians – Engineers will design new tools, engineer new technology and become the “player/coach” on the operating floor – More than ever, engineers will bridge the technical and business worlds to optimize financial performance in real time in a global market Chemical Engineers must “up skill” in the traditional core areas – Traditional basics more critical than ever – Design, modeling, reaction engineering, advanced control engineering – Acquire skills traditionally provided in graduate programs Must add other skills from non-traditional areas – Computing, computer control and optimization – Modeling at the molecular level – Economics and business – Leadership Entry level no longer just design and monitoring – Monitoring, operational advice, optimization largely by technicians – Engineers will design new tools, engineer new technology and become the “player/coach” on the operating floor – More than ever, engineers will bridge the technical and business worlds to optimize financial performance in real time in a global market Chemical Engineers must “up skill” in the traditional core areas – Traditional basics more critical than ever – Design, modeling, reaction engineering, advanced control engineering – Acquire skills traditionally provided in graduate programs Must add other skills from non-traditional areas – Computing, computer control and optimization – Modeling at the molecular level – Economics and business – Leadership

10. A Word on Globalization Chemical Engineers in the future will be part of a global workforce providing technical support and solutions in real time on a global basis – Industries and companies that can get this right will be the most successful – Ideas and technology advances will be deployed globally in near real time – Geographic mobility is a must Engineers will be located in plants and regionally, but will be linked by a single collaboration and knowledge management network – Work will be done by virtual teams – “Customers” for service will be global Chemical Engineers with foreign language skills and global experiences via internships or IQP/MQP will have an advantage in this global environment Chemical Engineers in the future will be part of a global workforce providing technical support and solutions in real time on a global basis – Industries and companies that can get this right will be the most successful – Ideas and technology advances will be deployed globally in near real time – Geographic mobility is a must Engineers will be located in plants and regionally, but will be linked by a single collaboration and knowledge management network – Work will be done by virtual teams – “Customers” for service will be global Chemical Engineers with foreign language skills and global experiences via internships or IQP/MQP will have an advantage in this global environment

11. Recruiting Model is Changing The need to improve efficiency is significantly changing the campus recruiting model A smaller number of target schools that have provided greatest recruiting success are now visited Summer Internships are more and more used to select and identify undergraduates for employment offers – Conversion of summer interns to regulars hires is a win-win for all – Retention and assimilation are much improved – Sophomores are now targeted for multi-year internships The need to improve efficiency is significantly changing the campus recruiting model A smaller number of target schools that have provided greatest recruiting success are now visited Summer Internships are more and more used to select and identify undergraduates for employment offers – Conversion of summer interns to regulars hires is a win-win for all – Retention and assimilation are much improved – Sophomores are now targeted for multi-year internships
