MEETING REPORT

Date: November 15-16, 2011 Place: Carib Hilton, San Juan, Puerto Rico Subject: Caterpillar Owners Group (COG) Meeting Attendees: See Appendix A

1. PURPOSE

The purpose of the meeting was to discuss technical issues pertaining to Caterpillar 3500 and 3600-series engines and diesel generators. Summaries of discussions that occurred are presented in the following sections. Appendix B contains a copy of the meeting agenda.

2. ADMINSTRATIVE DETAILS

The meeting was called to order at 8:25 a.m. on November 15th. Mr. William Wah (AEP), the current chairman of the COG, welcomed attendees. The attendees introduced themselves. Dr. Gary Thompson (MPR) updated attendees on the condition of Mr. Mark OConnell (MPR), the project manager of the COG, who could not attend the meeting for health reasons. A list of the meeting attendees is included as Appendix A.

Mr. Wah reviewed the agenda for the meeting. He also indicated that the minutes for the previous COG meeting in May 2011 had been drafted, but not issued. The approval of the minutes was deferred to allow members to review the draft and provide comments.

Mr. Wah reviewed the status of action items assigned during previous COG meetings. These actions, along with the person/organization assigned responsibility for completing them and their current status, are summarized in Appendix C.

Mr. Wah stated that he has continued to work on increasing membership in the COG. He stated that the Catawba Nuclear Power Plant was a potential new member, and that he would like to reach out to the plant and invite personnel to attend a future meeting. Mr. Wah asked the meeting attendees if it was OK for him to invite Catawba personnel to a meeting. The attendees were unanimously in favor of Mr. Wah doing so.

3. OPERATING EXPERIENCE

Members discussed failures that have occurred since the last COG meeting, including troubleshooting, cause determination and compensatory and corrective actions.

3.1 3608 FUEL INJECTOR FAILURES DUE TO CAVITATION

Mr. Matthew Sturr presented information regarding recent failures of fuel injectors on the Caterpillar 3608 Main Diesel Engines (MDEs) of 225 buoy tenders, including the USCGC ELM, USCGC HOLLYHOCK and other ships. A copy of Mr. Sturrs presentation is included in Appendix D.

Mr. Sturr reported that on one of the USCGC ELM MDEs, the Cylinder #2 injector failed in the compressed position. This resulted in excessive rocker arm to push rod clearance and caused damage to the push rod and rocker arm button. Mr. Chris Francis asked about the condition of the camshaft lobe for the affected fuel injection pump. Mr. Sturr responded that the cam survived; however, part of the rocker arm assembly was "mushroomed" by the push rod, and the pushrod and rocker arm assembly had to be replaced. Mr. Justin Providence asked how long the engine ran with the stuck injector. Mr. Tim Cotton responded that he was not sure and that he would have to ask. Mr. Providence added that the individual exhaust temperature probes should have picked up the stuck injector. Mr. Dale Jacobs responded that the injector could have been stuck for a few minutes before the ship realized there was a problem. He added that a similar problem also occurred on another USCG ship and the entire cylinder suffered damage.

The cause of the injector failures was first thought to be the result of water contamination in fuel tanks. The USCG investigated this cause, and considered cleaning fuel tanks as a potential solution. Mr. Sturr reported that the injector from the USCGC ELM was sent to Mr. Bob Hall (Caterpillar) for inspection. Mr. Hall determined that the injector failure was due to cavitation damage from insufficient fuel pressure and fuel aeration. During the meeting, Mr. Hall added that 3500-series engines are less sensitive to fuel pressure variations than 3600-series engines due to difference in injector design.

The USCG is working closely with Caterpillar to determine a solution for the problem. Specifically, Mr. Sturr asked Mr. Hall if Caterpillar wanted a platform to study the cavitation issue. Mr. Hall stated that Caterpillar would like to identify an engine where cavitation is a recurring problem, and then use that engine for testing. He added that they would like to make adjustments to the engine to make cavitation occur and stop, and take fuel pressure readings at various places during both. Mr. Hall presented a check sheet showing the locations where fuel pressure readings would be taken, and the recommended fuel pressures at each location. A copy of Mr. Halls presentation is included as Appendix E. Mr. Sturr stated that the USCGC ELM and/or HOLLYHOCK may be available for Caterpillar to use for fuel pressure testing. Mr. Hall requested that Mr. Sturr provide the injector failure rate for these two ships, as well as any available reports related to the failures. Messrs. Sturr, Hall and Mike Weiland (Caterpillar) discussed what gauges would be required to make the fuel pressure measurements on the USCG engines. Mr. Sturr asked for the part number for a gauge that could be used. Mr. Weiland replied that he would provide the part number. Finally, Mr. Sturr stated that the USCG would be interested in a booster pump option for the fuel system as a potential way of mitigating the injector failures. He added that Caterpillar might be able to learn something from Mustique since they have booster pumps (but on a C175 engine, not a 3600-series engine).

Mr. Michael Polonio stated that he is also interested in the cavitation issue, and that he planned to collect fuel pressure data for all of the 3600-series engines at Fortis TCI to send to Caterpillar.

Page 6 of 17

Mr. Hall asked Mr. Polonio if Fortis TCI was experiencing fuel injector seizures, to which Mr. Polonio answered "Yes."

Mr. Robert Gruszkowski (USCG) stated that the USCG is having more problems with remanufactured injectors than new injectors. Mr. Hall replied that remanufactured injectors use a new plunger and barrel set; however, this may have been a valid concern in the past because the remanufacturing procedure was not strictly followed. He also reminded attendees that all 3600-series injectors experience some level of cavitation.

3.2 3616 OVERHAUL

Mr. Francis presented information regarding the recent overhaul of one of the two Caterpillar 3616 engines at Bahamas Electricity Corporations (BEC) Marsh Harbour power plant on the Great Abaco Island. A copy of Mr. Francis presentation is included in Appendix F.

Mr. Francis stated that BEC has two Caterpillar 3616 generating units. The units were installed in 2001 and are rated at 4.4 MW each. Mr. Francis stated that the engines have had a number of problems recently, including (1) that they would not start (fuel coolers needed to be added), (2) their turbochargers needed to be remanufactured, (3) lube oil was found in the cooling system (due to faulty oil coolers), and (4) high lube oil consumption. He added that BEC is currently in the process of completing the second major overhaul of the engines.

Mr. Francis stated that BEC is currently concerned with high lube oil consumption on the MH#9 3616 engine. He stated that the unit had to be de-rated to 4.2 MW due to the oil consumption. Mr. Francis stated that no unusual wear of engine components that could lead to excessive oil consumption was found when the engine was disassembled for overhaul. He asked the group for possible reasons for the excessive lube oil consumption.

Mr. Hall stated that Caterpillar recommends cylinder heads with 30 valve seats in high ambient temperature applications (such as in the Caribbean) rather than heads with 20 valve seats.Mr. Polonio stated that Fortis TCI had problems with excessive lube oil consumption when using heads with 20 valve seats on their Caterpillar engines. He added that the plant is now using heads with 30 valve seats on the engines and the excessive lube oil consumption has stopped.Mr. Polonio stated that excessive lube oil consumption can occur if the oil mister is not properly adjusted and that it was very important for BEC to verify this. Mr. Osorio stated that he knows that BEC is using heads with 30 valve seats on the engine. Mr. Hall responded that the cause of the excessive lube oil consumption was probably not the type of cylinder head used.

Mr. Osorio stated that the MH#9 engine at BEC had an oil consumption of 0.724 gal/hr at 100% load, which is a normal value. Mr. Osorio provided information for estimating lube oil consumption, as well as the data for BECs lube oil consumption. These are provided in Appendix G. Mr. Providence stated that data from before and after the recent overhaul was needed to determine if there was, and continues to be, a lube oil consumption problem. Mr. Polonio stated that unless the level of wear is significant and visible, you cannot simply check the running surface of cylinder liners and make a conclusion about their contribution to excessive oil consumption.

Page 7 of 17

Mr. Francis stated that he wondered if the problem was related to the oil mister pump. Mr. Sturr stated that there is a procedure for properly calibrating the pump. Mr. Hall stated that the oil mister pump can be disconnected when using cylinder heads with 20 valve seats. He added that if this is done when using cylinder heads with 30 valve seats, then you need to check for valve recession. Mr. Polonio stated that if oil misters are adjusted and operating properly, then there is no need to disconnect them, regardless of which heads are being used. Mr. Hall responded that this was correct. Mr. Sturr stated that the USCG would like to disconnect the oil misters on the main engines of 225 buoy tenders. He added that he thought these engines would be good candidates for having the misters disconnected. Mr. Hall agreed.

Mr. Francis asked Mr. Hall if excessive oil consumption could occur for some other reason. Mr. Hall responded that he learned from his experience with engines on Turks & Caicos that valve guttering will occur when using cylinder heads with 20 valve seats in high ambient conditions. He added that engines will automatically come with 20 valve seat heads unless a customer specifically requests heads with 30 valve seats.

Mr. Francis asked what BEC should do if excessive lube oil consumption continues after the engine overhaul. Mr. Osorio stated that BEC first needed data to support that there really is high oil consumption. Mr. Hall stated that it is not recommended to operate engines at a constant, steady load when using cyclic heads. He added that if this is done, then inspections should be performed to confirm that valve recession is not occurring.

3.3 FUEL-RELATED ISSUES

Mr. Polonio presented information regarding Fortis TCIs experience with dirty fuel and the importance of fuel tank monitoring and maintenance. A copy of Mr. Polonios presentation is included in Appendix H.

Mr. Polonio stated that Fortis TCIs power plant is in Providenciales, which is the largest city in the Turks & Caicos Islands. For a long time, the plant used Caterpillar 3612 and 3616 generator sets for baseload power, supplemented by 3500-series trailer units. Recently the plant added an 8.7 MW Wrtsil generating unit.

Mr. Polonio stated that the power plant in Providenciales has experienced fuel-related problems for some time. The problems included a high rate of fuel filter blockages and need for replacement, and a high rate of injector failures. Prior to the addition of the Wrtsil unit, Fortis TCI blamed Caterpillar for the fuel problems. However, when the fuel problems also affected the new Wrtsil unit, the plant realized that Caterpillar was not the problem.

Mr. Polonio stated that the plant recently added a new 400,000 gal fuel tank, which provides fuel for approximately 10 days of continuous operation (~40,000 gal used per day). The old tank farm at the plant consisted of four 25,000 gal day tanks, which together only allowed for 2.5 days of continuous operation.

Page 8 of 17

Mr. Polonio stated that he asked plant personnel when was the last time the old tanks were cleaned. He added that no one could remember when they were last cleaned. Mr. Polonio stated that one of the tanks was isolated for cleaning and it was found to be full of sludge, etc. He added that since the volume of the day tanks was small (emptied every 2.5 days), the sludge in the tanks was constantly being stirred up and fed to the fuel filters.

Mr. Polonio stated that fuel had been consistently sampled from the tanks and sent out for analysis. However, the samples were taken from a convenient location that was not near the bottom of the tank. Mr. Polonio stated that the results for all fuel samples came back as good, which was not surprising because the samples were not representative of the tank contents. Mr. Polonio stated that he now uses a thief sampler to sample fuel from tanks. The thief sampler allows representative samples to be taken from anywhere in the volume of fuel.

Mr. Polonio stated that fuel sampled from the day tanks was much cleaner (lighter) after the tanks were cleaned. He added that he later noticed that the fuel sampled from the tanks began to get dirtier/darker again. Mr. Polonio stated that he suspected his fuel suppliers tanks were also dirty. To test this theory, he used the thief sampler to sample fuel from the suppliers tanks. These fuel samples were tested and were confirmed to be dirty.

Mr. Ed Guevara (USCG) noted that there must be a stability issue with the fuel. Mr. Polonio stated that the plant was trusting that the fuel going into and coming out of the tanks was OK. It now knows that proper fuel sampling and periodic tank cleaning is critical.

Mr. Cotton noted problems with the tank setup at Fortis TCI (shown in photos in the presentation in Appendix G), specifically that the tanks have a small volume and are above ground. As a result, they may be subject to temperature drops at night and condensation inside the tanks. Mr. Polonio stated that the Shell now deposits fuel into the 400,000 gal tank, and that there is a pipeline to the four 25,000 gal tanks, which are now used as day tanks. The fuel delivered by Shell originates in the Bahamas. Mr. Polonio stated that he has requested a profile of the supplier tanks.

Mr. Providence stated that Mustique has a 10,000 gal tank, which contains enough fuel for 4.5 days of operation. He added that when fuel deliveries are made, three representatives (one from each involved party) are present and three fuel samples are taken. Mr. Polonio stated that it is important to take control of the entire fuel delivery process.

Mr. Cotton stated that fuel stability and contamination is a big problem with marine fuel supplies on USCG ships. Mr. Vlez stated that he is aware of large fuel tanks in Puerto Rico that are simply refilled after the level drops to a set point. He added that sludge may have been at the bottom of these tanks for 10-15 years.

Mr. Guevara provided the group with information on fuel stability. He stated that it is important to perform a fuel stability test if storing fuel for a long period of time, as well as if paraffinic and naphlalenic fuels are mixed. He added that fuel stability guidance is provided in ISO 8217 DMA (Distillate Marine Grade A). Mr. Guevara accepted an action to upload ISO 8217 DMA information to the COG Projectview site.

Page 9 of 17

Mr. Sturr stated that the USCG is constantly having fuel issues. He added that the USCG now has a dedicated fuel expert who used to be with U.S. Navy.

Mr. Wah stated that D.C. Cook has 60,000 gal fuel tanks. The tanks are very clean because of checks that are imposed on the fuel supplier. Mr. Wah also stated that a reason that the fuel in AEPs tanks are very clean is that it turns fuel deliveries away. He added he realizes that plants on the Caribbean islands may not have this option. Mr. Wah showed to the group tables containing AEPs fuel specification requirements. A copy of these tables is included in Appendix I.

4. PARTS AND VENDOR ISSUES

Members discussed parts obsolescence, quality and availability issues, etc. This discussion included presentations by Caterpillar.

4.1 SERVICE LETTERS - CONTINUED PRODUCT IMPROVEMENTS (CPI)

Mr. Ren stated that service letters come from the CPI process. He added that he had prepared a list of service letters for the 2010-2011 time period. Mr. Wah asked if customers have access to service letter via sis.cat.com. Mr. Osorio replied that they do not. Mr. Ren stated that he would provide the list of service letters to the group.

4.2 CPI ISSUES FROM RECENT TC CONFERENCE

Mr. Ren provided feedback from a recent TC conference regarding how Caterpillar approaches and resolves CPI issues. He stated that each CPI issue includes a problem statement, a root cause investigation, and preparation of a Permanent Corrective Action (PCA). He added that CPI issues sometimes also include other things, for example, a field support plan.

Mr. Ren used the new factory torque setting for the fuel injector case-to-body (to eliminate overstressing and cracking in the threads of the body) as an example of a successful CPI process. Mr. Wah stated that the example helps illustrate that Caterpillar has a rigorous process for addressing and correcting problems. Mr. Ren responded that Caterpillar takes all failures seriously, and that customer satisfaction was the most important part of their business.

Mr. Ren stated that he would provide the new factory torque setting for the fuel injector case-to-body to the group.

4.3 UPDATE ON TIER 4 ENGINE COMPONENTS AND RETRO-FIT OPTIONS

Mr. Ren provided a brief update on engine components and retro-fit options related to new Tier 4 emissions standards. He stated that he had put together a list of website links containing information on various Caterpillar-related topics, and that one of the links covers emission reduction. A copy of the list generated by Mr. Ren is provided in Attachment J.

Page 10 of 17

4.4 CATERPILLAR ACQUISITION OF M OTOREN -WERKE M ANNHEIM

Mr. Ren provided information on Caterpillars recent acquisition of Motoren-Werke Mannheim (MWM). He stated that MWM produces gas engines, which is the main reason why Caterpillar wanted to acquire it. He added that Caterpillar would like MWM to maintain its identity and that at first Caterpillar and MWM will be run as two separate companies. Eventually, Caterpillar wants MWM to sell products through the Caterpillar dealer network; however, it does not want that addition to overwhelm the network. A copy of the Caterpillar press release regarding the acquisition is included in Appendix K.

4.5 SPECSIZER TOOL FOR GENERATING SETS

Mr. Ren provided information on Caterpillars SpecSizer software for determining the "best fit" generator set based on various input criteria. Files provided by Mr. Ren related to SpecSizer are included in Appendix L. Also, an interactive Microsoft Excel-based "Help" file has been uploaded to the COG ProjectView web site.

5. CONDITION MONITORING / PREVENTIVE MAINTENANCE

Members discussed reliability improvements, planned maintenance changes and asset management strategy updates, including parameters monitored, preventive maintenance frequency optimization and critical spare parts strategy.

5.1 USCG LUBE OIL ANALYSIS PROGRAM

Mr. Guevara presented information on the USCGs lube oil analysis program. A copy of Mr. Guevaras presentation is included in Appendix M.

Mr. Guevara stated that he would like to improve the USCGs lube oil analysis program. He stated that an effective program can detect engine problems early and reduce the extent and cost of failures. He added that the potential cost savings from an effective program are large.

Mr. Guevara reported that the USCG currently only performs on-shore testing of lube oil. Three different laboratories are used. There is no consistency in the results provided by the labs, and there is currently no central database for storing test results. Mr. Guevara stated that an effective program required the use of both ship-board testing using hand-held equipment and on-shore testing at a commercial laboratory (preferably ISO certified).

Mr. Cotton stated that in 20 years of oil analysis, the USCG has never caught a single-point catastrophic failure. Based on this, he stated he did not understand why the USCG was looking to spend $500,000 per year on oil analysis. Mr. Polonio stated that in his experience, oil analysis can be beneficial if it is done right. He stated that Fortis TCI has used oil analysis results to identify engine problems in an early stage of development. He added that lube oil samples need to be collected consistently and labeled well, and the analysis results analyzed in detail. Mr. Jacobs stated that implementing an effective lube oil analysis program on ships is difficult.Specifically, samples are taken once per week; however, three samples can go out for analysis at

Page 11 of 17

the same time because of how infrequently mail is sent out from the ship. Mr. Gruszkowski stated that the benefits of oil analysis are also negated by the high frequency of lube oil changes on the ships (every 500 hours).

Mr. Guevara stated that the above points illustrate the importance of having good on-board oil analysis capabilities. He added that lube oil analysis, even with the best program implementation and results, will not identify every catastrophic failure before it occurs.

5.2 CATERPILLAR SOS OIL ANALYSIS

Mr. Wah initiated a discussion about Caterpillars SOS oil analysis program. He stated that he wanted to have a lube oil sample analyzed in the program; however, this did not occur because a Caterpillar representative was not permitted to collect the sample due to plant security. Instead, the sample was collected by AEP personnel and sent to Herguth Laboratories for analysis.Mr. Wah showed Herguths analysis results to the group (the results are included in Appendix N).

Mr. Weiland stated that Caterpillar does not need to collect a sample for it to be analyzed by the SOS program. He added that AEP can collect the sample and send it to Caterpillar. Mr. Weiland also noted that wear metal parameters that are quantified in an SOS oil analysis are based on Caterpillars global experience and are proprietary. He also stated that some important wear metals are not listed in the Herguth reports.

Mr. Wah stated that he would pursue SOS analysis of lube oil from D.C. Cooks Caterpillar engine with his local dealer.

6. TRAINING

6.1 TRAINING BY CATERPILLAR AND /OR ITS DEALERS

In response to a request for an update to Action Item #13 from the December 2010 COG meeting, Mr. Vlez stated the RIMCO provides training within its territory as requested by utilities. Mr. Wah asked if he would have to contact his local dealer for training. Mr. Vlez responded "Yes." Mr. Polonio stated that some dealers are too small to offer training, and asked if training could be coordinated for multiple groups at the same time. e.g., a regional course. Mr. Vlez stated that RIMCO could handle 4-8 people for training in their facility. Training could also be held at a remote site, e.g., the recent 3600-series training that RIMCO held at DOMLEC for two people.

Mr. Polonio stated that Fortis TCI is interested in sending employees for training, and that he needed to know when training classes would be held. Mr. Vlez stated that Mr. Polonio should make a training request, and RIMCO will work with M&E Ltd. to arrange the training. Mr. Vlez added that if RIMCO has space available in upcoming training classes, he can pass on the number of available spaces to Mr. Osorio so he can announce the openings to utilities in the M&E Ltd. region. Mr. Vlez stated that 3600-series training would be held in April 2012. Mr. Wah stated that it would be nice to know when training spots are open.

Page 12 of 17

Mr. Ren asked Mr. Vlez how extensive is the training provided by RIMCO. He stated that he asked because Caterpillar does not want end users doing hardcore internal work on engines. Mr. Vlez responded that RIMCO does whatever training a utility asks for. He added that RIMCO has a core training program, but can also provide information and training for additional items, as requested. Mr. Ren stated that Caterpillar does not want customers performing work for which they do not have expertise or the proper tools. He added that this is especially critical if a product is still covered under warranty. Mr. Providence stated that all customers should be given the same information. He added that knowledge is power, and all customers should know what is OK and not OK to do. Mr. Sturr stated that for the USCG, only CAT-certified technicians should be working on engines since Caterpillar may not honor a warranty if a non-certified person performs the work. He added that when subcontracting out the work, it is often difficult getting certified personnel. The USCG usually chooses the cheapest option, which could end up being someone like "Mom & Pop Katerpillar."

Mr. Guevara stated that he expects there are different levels of certification. He asked Mr. Vlez if RIMCO provides training and issues different levels of certification. In response, Mr. Vlez showed an example of a training agenda prepared for a St. Maarten utility, which was conducted over a period of four days at RIMCO. He added that after this training was completed, the utility asked for a "second level" of training as a follow-up. He stated that the cost of the training was US$4500.

Mr. Francis asked about RIMCO providing training for BEC. Mr. Vlez stated that the BEC personnel could travel to RIMCO or that RIMCO could travel to the Bahamas. He added that for either option, BEC would need to coordinate the training through M&E Ltd. since they are BECs local dealer. Mr. Osorio stated that M&E Ltd. does not have all of the special tools required for 3600-series training (e.g., for a major overhaul) and typically will use a utilitys tools.

Mr. Wah stated that at AEP, a factory representative will come in and direct/supervise AEP personnel, who will perform the work on the engine. He added that for work on Cooper Bessemer engines, two factory representatives would be dispatched, one for the day shift and one for the night shift. Mr. Vlez stated that training styles and information would be different for each utility. Mr. Osorio stated that for recent overhauls at BEC, M&E Ltd used BEC personnel for some labor, cleaning, etc. He added that when performing overhauls, one lead technician is needed to perform work, as well as to supervise what other personnel are doing. He stated that M&E Ltd. does not have the facilities and resources to perform extended training; however, he can work with RIMCO to coordinate the training, if requested.

Mr. Francis asked about training for fuel injectors. Mr. Vlez stated that RIMCO does not provide training for injectors for liability reasons. Mr. Ren asked Mr. Vlez if RIMCO provides training for overhauls. Mr. Vlez responded "Yes."

Mr. Providence asked why there is a need for extensive training. He stated that engine design has not changed much, and utilities should already have a core of trained staff (engineers, mechanics, fitters) to perform most work. He added that training should only normally be

Page 13 of 17

required for new updates. If a utility has an engineer (or engineers) on staff with an extensive fundamental knowledge of engines and significant experience, then only the additional knowledge of specifics and what tools to use should be needed. He asked why training does not cover only the specifics. Mr. Ren stated that Caterpillar is a world-wide organization and does not have the resources to provide training to customers themselves. He added that because of a lack of resources, Caterpillar even finds it difficult to provide all of the necessary training to its own dealers.

Mr. Gruszkowski stated that the USCGs approach to training/maintenance is to provide specific training to support organic resources. He added that technicians needed to be qualified and current. He stated that for post-warranty issues, if specific information can be pushed to these organic resources, then this frees up resources for Caterpillar to work on bigger issues.Otherwise, the Caterpillar resources are always tied up with smaller, less important issues. For warranty issues, Caterpillar should be involved with everything, no matter how small.

Mr. Polonio stated that training is viewed as a win-win scenario at Fortis TCI. He stated that Caterpillar used to handle certification programs in Peoria. This was preferred since Caterpillar knows what level of training people need. He added that the problem now is that the training of the next generation of personnel is being performed by the older generation, who are no longer certified. He stated that a training program is needed, and the program should state what training is needed to be certified to a certain level. He added that there is a need to get employees up to a consistent level of training/knowledge.

Mr. Vlez stated that RIMCO likes to perform training for utility personnel; however, it needs to train its own personnel and there is not much time left to train others. He added that the needs of each utility are different, which is also a problem when trying to provide training. Mr. Osorio stated that M&E Ltd. cannot issue a "certification" with training due to liability issues. He added that if a certification is desired, then Caterpillar should provide the training. Mr. Ren stated that Caterpillar also will not issue a training certification due to liability issues. Mr. Polonio stated that he was not focused on certifications, but rather was focused on knowledge. He added that any training should include a testing aspect.

Mr. Guevara stated that general knowledge/training is needed before specific training is provided. He stated that many people go out on USCG ships without any general knowledge or training. He added that engineers, etc. need to know the basics first, or specifics will not help out much. Mr. Ren stated that the USCG needs to talk to dealers in the U.S. regarding training.Dealers in the Caribbean do not have enough resources to support the USCG, except maybe for the USCG assets in Puerto Rico. He added that for Caribbean utilities, only RIMCO (no offense to M&E Ltd.) is set up to provide the level of training needed.

Mr. Jacobs stated that training for the USCG can differ depending on what a specific dealer can and does provide. He stated that there needs to be a standard within Caterpillar, e.g., training for 3500-series engines includes the following ... . Mr. Ren stated that Caterpillar pushes responsibility for training to its dealers. To receive a standardized level of training, an organization should choose one dealer for all training. Mr. Jacobs stated that this can be difficult for the USCG since ships often cross regional dealer boundaries. Mr. Ren stated that training

Page 14 of 17

cannot be exactly the same at different dealers. Messrs. Jacobs and Providence stated that the core fundamentals of any training should be the same at different dealers, though. Mr. Ren stated that RIMCO has a training course structure set up. Each organization needs to go to its local dealer to discuss what their own training program contains.

Mr. Wah stated that personnel used to be able to go directly to Caterpillar for training. Mr. Ren responded that Caterpillar no longer has the resources to provide training. There are now too many products in numerous regions of the world, and as a result, Caterpillar has to rely heavily on its dealer network. Mr. Sturr stated that the USCG developed "CAT 101" in conjunction with Caterpillar, and that it is available on the COG Projectview site. Mr. Jacobs discussed additional issues regarding the Defense Products group of the USCG. He stated that some engines are restricted because they are defense-related, and dealers cannot look up information/parts for restricted engine serial numbers. Mr. Gruszkowski asked Mr. Ren if Caterpillar still maintains the training materials that it used in the 1970s and 1980s.

Mr. Francis stated that personnel no longer receive certification for training by Caterpillar. He asked the USCG members what they receive when they get training from dealers. Mr. Cotton responded that they receive a "certificate of analysis." Mr. Francis asked if Caterpillar recognizes this certificate. Mr. Ren responded "No" and asked Mr. Francis why having a training certification is necessary. He added that Caterpillar will not honor training certificates issued to a 2nd party (the dealer providing the training is the 1st party) due to liability concerns.Mr. Francis responded that certification may be important within an organization for promotions, raises, etc. Mr. Ren stated that training (or a training certificate) does not really mean anything. If an engine is under warranty, then Caterpillar should be performing the work. If the engine is out of warranty, then it is the customers engine to work on and repair or damage.

Mr. Ren stated that he has prepared a list of core training topics for Caterpillar dealers. To become "certified," it would take 3-5 years to complete all of the recommended courses on the list. He stated that there is not one single training class that you can take to become certified. Mr. Ren stated that Caterpillar not only does not have the resources to provide training to customers, it does not have resources to provide training to all of its dealers technicians. As a result, Caterpillar has to tell dealers that some of technicians are not authorized to go out to customers and provide service. Mr. Ren stated that not all people who have been trained to train are good teachers. He stated that Caterpillar has "trainer trainers" whose mission is to train the dealers trainers to be good teachers.

6.2 TOUR OF RIMCO CATERPILLAR

Members participated in a tour of the RIMCO Caterpillar facility on the morning of Wednesday, November 16, 2011. Members were able to see the wide range of products and services that RIMCO is able to offer Caterpillar clients in Puerto Rico and the surrounding Caribbean area.

7. COG BUDGET, PLANNED / PROPOSED TASKS AND GROUP STATUS

7.1 BUDGET STATUS

Dr. Thompson stated that as of the meeting, only two members had paid the COG dues for 2011.

Timely payment of dues by all members is key to the effectiveness and longevity of the owners group. Please work to have outstanding dues paid as soon as possible.

7.2 PLANNED / PROPOSED TASKS

Mr. Wah stated that it would be helpful for the group to review minimum training standards recommended by Caterpillar and used at each utility. Mr. Wah recommended that the group contract with MPR to perform the review. Dr. Thompson accepted an action for MPR to provide a proposal for the review by the next meeting.

7.3 STATUS OF COG

Mr. Wah stated that he thought the status of the group was good. He apologized for MPR and himself being behind schedule on preparing the minutes from the previous meeting and the agenda for the current meeting. He stated that he was pleased with the groups discussion and thought that it had good technical content.

8. CLOSING ITEMS

8.1 REVIEW OF ACTION ITEMS

Dr. Thompson reviewed the list of action items assigned during the meeting. The list of items is included in Appendix C.

8.2 COG EMAIL SIGNATURE

Mr. Wah requested that "www.cog.mpr.com" be added to the signature of COG-related emails.

8.3 DEADLINES FOR ISSUE OF M EETING AGENDA AND M INUTES

Mr. Wah requested that the COG and MPR set deadlines for the issuing of meeting minutes, solicitation of meeting topics for an upcoming meeting, and the issuing of a draft meeting agenda. The following deadlines were agreed to:

x Meeting minutes - Issued within 60 days after the meeting ends

Page 16 of 17

x Agenda topics - Email request sent out 45 days prior to start of next meeting; members/attendees to respond with topics during next 15 days

x Draft agenda - Emailed to members 30 days prior to start of next meeting

8.4 FREQUENCY OF M EETINGS

Mr. Wah asked members if meeting twice per year was too frequent. Most members replied that having two meetings per year was acceptable, and that the round table discussion should be more efficient and preferably limited to one day. Mr. Ren stated that he questioned the value of semi-annual meetings because many members did not submit questions or concerns for discussion at the meeting. He added that it would be valuable to have members prepare presentations describing operating experiences, best practices and other topics.

8.5 NEXT M EETING DATE AND LOCATION

The group agreed that the next meeting of the Caterpillar Owners Group will be held in Lafayette, Indiana. The target schedule for the meeting is May 15-16, 2012. Mr. Ren stated that it should be OK to schedule the meeting for this week. He added that a concern was scheduling the meeting around the Indianapolis 500 race, during which hotel vacancies are scarce. A tour of Caterpillars 3516 production facility may be conducted on the morning of Wednesday, May 16th.

8.6 ELECTION OF NEW COG CHAIRMAN

Mr. Wah asked for volunteers to be considered for election as the new COG chairman. Mr. Polonio also suggested, for continuity sake, that an assistant chairman be elected no later than one year prior to the current chairman stepping down and that the assistant chair automatically move in to the chairman role (i.e., a chair-in-waiting). Mr. Wah indicated that a charter revision would be required to define the role of the assistant chairman and the rules of succession. He stated that he would revise the charter and send out a draft for review and signatures.

The COG selected Messrs. Sturr and Providence as the new chairman and assistant chairman, respectively.

Particulate Contamination (1) [TRM TSR 8.8.2.1]

D2276-83 1 / 10 years < 10 mg/L 12

(1) TRS 8.8.2.1 reads: !Clean each fuel oil storage tank by: a. Draining fuel oil storage tank, removing the accumulated sediment, and cleaning the tank; OR b. Agitate the fuel oil in the storage tank while pumping the oil from the bottom of the tank through a 5-micron filter, and back to the opposite end of the tank. Three consecutive samples shall be taken and analyzed in accordance with ASTM D2276-83. If the contaminant level in any of the samples is greater than 10 mg per liter, the agitation, filtration, and sampling processes shall be repeated. If the contaminant level remains above 10 mg per liter after 3 iterations, the draining, and cleaning method described in TRS 8.8.2.1.a." Therefore the particulate contamination surveillance requirement every 10 years is performed only if option !b" is being performed.
