© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 21 iPEC Benefits You Can Sell

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 22 Benefits For the Owner  Money, in many cases the iPEC can be one of the last things delivered to the project. This allows the owner to: ▼ Keep his money till the end thereby earning interest – no progress payments on equipment that sits in the basement un-used (better cash flow). ▼ No issues of extended warranties ▼ Lower Cost – Life cycle analysis  More space for earning income. GLA – Gross Leasable Area or just increased building space for multiple uses  Possible savings on taxes. ▼ Unlike a field built penthouse, the ETL listed iPEC does not get taxed as real estate or part of the building, which is depreciated over a 50 year life. iPEC is equipment and depreciated over a 10 year period improving cash flow.  Packaged Equipment Design Concept built in parallel w/ construction schedule has potential to reduce overall construction schedule – saving dollars.

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 23 Benefits For the Owner  Many Ancillary Costs are functions of the square footage of the building: parking lot as an example. The iPEC is a piece of equipment and not considered in the total sq.ft. of the building. ▼ As Equipment the code may not require it to have life safety’s: fire sprinkling, etc. ▼ Extreme case – max building height – field built unit included in total building height. iPEC unit considered equipment not included in building height.  More roof usage over a field built ▼ IBC required a field built to occupy 33% max of the roof plate. ▼ The ETL listed iPEC can occupy 100% of the roof plate.

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 24 Benefits For the Owner  Value ▼ Quality – Factory built in a controlled environment by experienced craftsmen building similar equipment everyday. ▼ Energy Efficient Product – Improved Building Cash Flow yields a more valuable building – greater bowering power ▼ Tenant Comfort – tenants leave buildings because they are not satisfied with the HVAC system. Give the control of temperature, humidity and noise (quiet) and they will stay. ▼ Reliable Systems – Mammoth has a 25+ year track record of building iPEC systems that work and stay online. ▼ Maintainable Systems – Mammoth designs enough space between components to make maintenance easy – and therefore it will get done. Most of the buildings HVAC components are in one location again making maintenance easy. ▼ Longevity- iPEC Systems are designed for 30+ year life expectancy

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 25 Benefits For the Architect  They have a unique concept with features to sell the owner ▼ More usable space ▼ Packaged Equipment Design Concept has potential to reduce overall construction schedule – saving dollars. ▼ Possible tax savings ▼ Exterior Curtain Wall options equal to Field Built ● Brick, Glass, Special Metal, etc.  Suitable for Fast Track projects ▼ Pre Engineered Designs ▼ Reliable prove Designs  Use the iPEC in lieu of a screen wall ▼ Screen Walls are very expensive – need to handle wind load therefore they are secured to the super structure ▼ Saves the project money  More interior room usage means more interior design and fit out

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 26 Benefits For the GC or CM  Time ▼ Project schedules are met meaning savings to them ▼ Less time on finding space for equipment location ▼ Packaged Equipment Design Concept has potential to reduce overall construction schedule – saving dollars.  Fewer and less talented construction managers required  Not relying on the low bid contractor (Higher Quality System)  Less chance of back-charges due to incomplete drawings  Less risk (general terms and conditions) ▼ With the iPEC they may be able to save on things like ● Supervision ● Insurance ● Cleanup ● Strikes ● Trade Co-Ordination (several trades needing to work in the same area of the building)

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 27 Benefits For the Mechanical Engineer  Time and Money ▼ Mechanical Engineer delegates Mammoth to design the Mechanical Equipment Room. Allowing the engineer to spend his time on other issues. ▼ Mechanical Engineer’s fees are not increasing – allowing Mammoth to work on the Equipment Room layout details will increase their efficiency and increase their $/Hr. Their fees will include things typically not seen in their scope ● Electrical ● Plumbing and piping ● Controls ▼ Less field time as the work is not dependent on the low bid contractor ▼ Packaged Equipment Design Concept has potential to reduce overall construction schedule – saving dollars.  They have something to sell the architect ▼ Features not availed in a standard unit or even a field built  They have more control of the entire mechanical system

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 28 Benefits For the Mechanical Engineer  Suitable for Fast Track projects ▼ Pre Engineered Designs ▼ Reliable prove Designs

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 29 Benefits For the Mechanical Contractor  Greatest Financial Risk – Error in the estimation of labor ▼ iPEC has a Fixed cost = no risk  Time and Money ▼ They are working on other areas of the building while Mammoth is building the iPEC ▼ The iPEC Equipment Mark up $ will include monies typically earned by other trades ● Electrical ● Plumbing and piping ● Controls ▼ iPEC are pre-commissioned at the factory ● Yields faster field commissioning –Yields faster CO – certificate of occupancy »Yields faster payment ▼ Less field time allowing them to secure other business for increased profit

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 30 Benefits For the Sales Representative  Money ▼ Reduced Competition – higher probability of a sale ▼ iPEC is a system ● with Multiple components – larger $ sale  Self Actualization ▼ Realization of one’s professional potential ● Selling a iPEC is satisfying beyond the dollars earned –Involvement on multiple levels – design, construction, etc.

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 31 Responsibilities For the Sales Representative  Understand iPEC details in order to articulate them to: ▼ consulting engineers – creates confidence in the engineer of your abilities ▼ the bidding contractors – discuss contractor labor requirements: example Mammoth provides spool piping pieces that cross sections. Spool pieces come with one end grooved for Victaulic couplings, contractors field responsibilities are to cut and groove the other end – rep needs to tell contractor estimated time – 2 men 20 hrs. ( other issues– set/rig and seal units, number of unit splits, unit is single point electrical but there are electrical splits – Molex connectors and terminal strips for high voltage, unit has no pipe insulation, duct and water and drain connections, cut out temp bracing, flange connections, how many tech screws and caulk, etc ● Benefits – gain contractors confidence in you and the equipment ● Contractor will not over estimate the installation of the iPEC which could put the whole project in jeopardy ▼ You may have to hire a local construction estimator and go over scope ● Ask for 3d piping diagrams – evacuation of the system ▼ Before sale try to get CM or Owner to buy (some experienced reps sell turnkey)

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 32 Responsibilities For the Sales Representative  Understand iPEC details in order to articulate them to: ▼ After sell – scope review ● Conduct meeting between Arch., GC,CM,ME,and MC on who is responsible for what relative to released submittals- sign in sheet, keep meeting notes, distribute notes ▼ Reduce Back Charges – everyone clear on their responsibilities ▼ Offer factory visit.- carry money in the order for this ● Carry a camera, for video of trip ● Make sure everything lines up before it gets to the job site ▼ Price in Rigging Supervision – always use a spreader bar! And use all pick points! ▼ Price in Installation Supervision ▼ Inspect and take photos – loose parts inventory at the riggers yard ▼ Commissioning Unit – Commissioning Agents make it clear w/ support get proper documents/support – control points, trip safety's, etc. ▼ Warranties – inspection services, etc

© 2004 Venmar CES Inc.© 2006 CES Group - Confidential 33 Responsibilities For the Sales Representative  How to Sell iPEC ▼ Look at total load – building diversity (office, solar, people), one large unit may take advantage of building diversity and meet requirements with less capacity reduced tons when compared with multiple smaller units. (Maybe Larger Supply Duct which could be a negative) ● Fewer Picks, EEAP spread sheet, size, # and wt of pieces, # of trucks, ▼ No detail on Bid documents (black box) ▼ Budget Bid
