(DTD) is the nation’s most experienced provider of near-surface horizontal systems for environmental remediation and water resource development. DTD specializes in environmental applications of guided boring technology, including the installation of remediation wells and venting systems, as well as groundwater resource development. DTD also has a developing reputation for successfully completing complicated river crossings, infiltration wells, and pipeline installations. DTD is managed and staffed by environmental professionals, including registered professional geologists, engineers, and construction managers. We are committed to maintaining our position as the leader in horizontal remediation systems through skilled project management, attention to detail, and continued training. Moreover, we are committed to continual innovation to increase the sustainability of environmental and water resource development projects. DTD operates from offices on the Atlantic and Pacific Coasts, with a satellite operation in Texas – facilitating our ability to service clients across the country. Directed Technologies Drilling, Inc. traces its roots to one of the pioneering firms in the industry, FlowMole Environmental Services Corporation. As a joint-venture between UTILX, a trenchless technology contracting company, and UNOCAL, a major oil production and retailing corporation, FlowMole Environmental Services was responsible for many of the technical achievements now routinely used in horizontal directional drilling for environmental applications. The FlowMole staff was responsible for the installation of nearly half of the horizontal environmental wells installed in the early 1990’s. The senior FlowMole team now leads DTD. Every DTD project is managed by an experienced project manager to ensure that each remediation system is installed safely and as designed. Horizontal well applications combine a variety of individual components into a complex system. The ultimate performance of each system depends on the proper design, selection, installation, and operation of all of these components. Our goal is total quality performance. We are continually working to improve our equipment, methods of installation, and the materials we install to ensure that every system delivers the required performance. Our experience in the field enables us to conceive, design, and apply innovative approaches in equipment specification, installation techniques, and materials. As a result of this innovation, DTD and our employees either hold or have applied for patents for a variety of HDD-related inventions. PAGE 2 REMEDIATION CONTRACTING SERVICES DTD uses horizontal and directional drilling technology to install environmental remediation wells, water resources wells, and associated infrastructure (conveyance lines, control systems, etc.) For larger non-environmental projects, we employ our midi-class HDD equipment to complete difficult stream or river crossings, and similar pipeline or utilities conduit installations. Environmental Applications DRILLING EQUIPMENT, MATERIALS & SPECIFICATIONS DTD maintains our equipment inventory in a high state of readiness, with regular maintenance, cleaning, and painting. Our standard is to maintain a high-quality image on your project site with clean equipment and a professional crew. DTD owns and operates a fleet of drill rigs manufactured by Vermeer, CMS, and American Augers, and modified for our specific use. These rigs range in size from small rigs suitable for back-lot operation in residential areas, to large rigs suitable for extended and difficult well installations. With our equipment inventory, we can select the appropriate drill rig to install remediation systems ranging from a few tens of feet of small diameter PVC pipe, to systems 2000 feet in length with large diameter steel casing. DTD’s current equipment inventory includes: Rig Thrust/Pullback Torque Vermeer 10x15 10,000 lbs 1500 ft-lbs Vermeer 24x40 (2) 24,000 lbs 4000 ft-lbs CMS 6015 60,000 lbs 15,000 ft-lbs CMS 100 100,000 lbs 30,000 ft-lbs American Augers D210 210,000 lbs 25,000 ft-lbs Horizontal directional drill rigs used by DTD advance a boring through the soil using a combination of thrust (equivalent to “downpressure” on a vertical rig) and cutting at the face of the drill head, using small high pressure jets of drilling fluid or mechanical cutting heads. The fluid jets cut the soil and then very quickly lose their cutting power. As a result, excessive soil erosion and overcutting do not occur using either Soil Vapor Extraction Soil Venting Bioaugmentation Chemical Injection Groundwater Extraction Air Sparging Ozone Injection Oxygenation Soil Sampling Potable Water Wells Shallow Radial Wells Conveyance Lines Treated Water Infiltration Dual Phase Extraction Passive sampling Figure 1 DTD American Augers D210 PAGE 3 cutting method. This process has been proven for boring under roads, in sandy areas, coral, and other difficult drilling conditions unsuitable for conventional utility water-boring techniques. By physically cutting a hole and removing excess spoils, the transmissivity and permeability of the borehole are not compromised. This is a frequent problem with drilling methods that simply displace and compact spoils into the borehole walls. We have worked with manufacturers to improve rig performance in environmental work, and to improve the specialized drilling, reaming, and navigation tools we use in the field. For example, working closely with engineers from Straightline, DTD has developed expertise in the use of steerable downhole hammers, extending our drilling capabilities to advance borings in material types ranging from soft sand to hard, fractured bedrock. DTD field crews typically range from three to eight people, managed by an experienced supervisor, who also acts as the site Health and Safety officer. All of our field employees have completed OSHA HAZWOPER 40 hour training, and are current with refresher training prior to field operations. Our field managers have additional HAZWOPER management training, and can operate field monitoring instruments, if needed, to assure health and safety of field operations. All field managers are experienced environmental scientists or geologists, and most are registered professionals in one or more states. Support Equipment Mud Systems To support our drill rigs, DTD owns mud mixing and recycling systems that are matched to drill rig capacities, as well as pumps, hoses and piping, and ancillary support equipment. We also own self-contained, totally enclosed trailers for equipment and tool transport. These trailers improve site security and prevent equipment theft and vandalism, as well as providing a discreet appearance at Figure 2 DTD Vermeer 24x40 rigs Figure 3 - DTD Small Mud Recycler PAGE 4 sensitive environmental remediation sites. Drilling Tools DTD works closely with manufacturers and custom machinists to fabricate specialized tools for installing remediation systems. One of DTD’s significant contributions to the field is a set of tooling and a method (patent pending) that enables us to install single-ended, or “blind,” wells through the drill string, but detaching and abandoning the drill bit downhole. This method provides a high level of assurance that the well screen and casing can be installed even in difficult, collapsing bore conditions. Some additional examples of custom tools designed and fabricated to our specifications include pilot drills for hard coral formations and soft sand, borehole reamers, forward reaming assemblies, and pipe-pulling assemblies. DTD has developed considerable expertise in soil sampling through directional bores. To advance this technology, we have modified commercially available samplers and have developed new designs to facilitate the collection of undisturbed samples for chemical analysis and geotechnical testing. Several of these prototype samples are currently under development and will be submitted for patent approval. In addition to these tools, DTD engineers and geologists have also invented and patented specialized well casing and well construction methods, adapted to specific horizontal well applications. The patented EnviroFlex well casing is one such product, comprising a well screen with an integrated filter material to prevent silt or sand infiltration into a well in fine-grained formations. DTD holds the patent to this product and is the sole provider of the material. Tracking and Steering Systems The drill head tracking and steering systems used by DTD are designed and built by several manufacturers, and have been selected on the basis of their applicability to our typical drilling scenarios and conditions. Tracking and steering of the drill head are related functions based on detecting and interpreting a signal transmitted from the drill head during installation of the pilot hole. DTD uses navigation systems that can operate at depths up to approximately 80 feet, depending on site conditions. We have walkover and remote systems available, and can typically maintain an accuracy of approximately two inches down to a depth of approximately 12 feet. Below 12 feet, we often maintain an accuracy of two percent. For deeper bores, we frequently work with industry leaders like Sharewell and SlimDril, who provide navigation and steering services using external coil systems and gyroscopic steering tools. These systems provide highly-precise, real-time navigation and steering capabilities, with the ability to detect minute steering deviations and make corrections on-the-fly. Drilling Fluids Drilling fluids are used to cut the soil, cool the drill bit, increase borehole integrity, and transport soil cuttings out of the borehole. Spent drilling fluids from Figure 4 - Walkover locating system PAGE 5 environmental remediation installations constitute potentially hazardous wastes and must be handled in strict accordance with applicable laws and regulations. DTD has worked closely with drilling fluid manufacturers such as Baroid and CETCO to assist in the development of drilling muds that are optimized for use in the environmental remediation industry and work well for horizontal well applications. Our experience with the use of these biodegradable polymer muds is unsurpassed within the HDD environmental industry. Our use of mud recyclers, where appropriate, reduces costs for clients through re-use of drilling fluids during well drilling operations, and through waste reduction, reducing the volume of contaminated fluids that must be disposed. With the advent of steerable downhole air hammers, DTD has also developed capabilities to accurately drill relatively complex bore configurations in solid rock or difficult cobble conditions using only compressed air as the drilling fluid. This capability is particularly useful in drilling fluvial deposits adjacent to or beneath rivers, where the potential for migration of conventional drilling fluids into the river exists. Well Design and Materials Selection Well screen selection is nearly always a compromise, balancing the desire to optimize flow rate with the need to control sedimentation within the well. Horizontal remediation well designers must juggle these same variables, but must also consider the difficulties of construction to a greater extent than they would in a vertical well. With more than 400 wells installed, under a variety of subsurface conditions and many different installation environments, DTD has gained significant experience in determining well configurations that can be practically constructed and will continue to operate effectively. We frequently work with clients to optimize their designs, and can assist with the design and layout of remediation systems, including well configurations, slot sizing and spacing, etc. We have also developed unique well designs for challenging site conditions, and we hold and have applied for patents on innovative well screen materials and well construction methods. GENERAL SPECIFICATIONS FOR HORIZONTAL REMEDIATION WELLS ? Depth: 3-400 feet below ground surface ? Diameter: 2-24 inches ? Length: Up to 4,000 feet (Note: the above specifications are co-dependent and will tend to limit one another as the maximum of each range is approached. Other factors can also greatly influence the achievable borehole configuration.) ? Accuracy: Horizontal wells can be placed with an accuracy of approximately 2 inches to a depth of 12 feet and approximately 2% at depths greater than 12 feet, depending on conditions. ? Soil types: Drilling is possible in most soils. We have installed wells and conduits in solid bedrock and beneath large rivers. Large cobbles and unconsolidated materials require larger drill rigs, and may utilize directional air hammers or downhole mud motors to advance the bore. PAGE 6 ? Approach length to desired screen depth: Approximately 3-5 feet horizontal for every foot of depth to the screened interval is required for all horizontal wells; a staging area may also be needed for some types of well materials. ? Drilling fluid: DTD is experienced in the use of various biodegradable polymers or gum-based fluids, including various additives to meet specific site conditions. Typical drilling fluid additives include guar gum and xanthan based products. Because they are difficult to clear from the well, and can severely reduce the permeability of soils surrounding the well, high-solids fluids such as bentonite are typically used only for conveyance lines. In some drilling conditions, a steerable downhole air hammer is an option. ? Drilling spoils: Drilling activities will typically produce spent fluids equal to approximately one or two times the volume of the borehole (e.g., 1-4 gallons per foot for a 6 inch borehole), although the actual volume of spoils will depend on the type of soil and site drilling conditions. At most sites, dilution of contaminants in the cuttings by drilling mud downgrades the spoils from a hazardous waste, which permits disposal as a solid waste in most municipal landfills. ? Site requirements: A source of water is required to mix drilling fluids; a fire hydrant is typically used. The drilling systems are otherwise self-sufficient. We need a disposal location for unused, uncontaminated drilling fluids. ? Well development: A variety of enzyme and other drilling fluid thinning agents can be used to clear the well of drilling fluids and thereby reduce skin damage to the surrounding formation. DTD has developed several specialized delivery and purging systems to aid in the proper development of horizontal wells.

CORPORATE EXPERIENCE Directed Technologies Drilling, Inc. is the nation’s leading team for near-surface environmental horizontal well design and installation. Since our inception, our team has installed over 400 wells throughout the country. The specific experience gained by DTD in the design and installation of horizontal extraction wells for environmental remediation is unparalleled by any other drilling or construction organization. Projects listed below are representative of the types of project that DTD has successfully completed. _____________________________________________________________________ Shaw Environmental Naval Base Pt. Loma, San Diego, CA LNAPL Recovery Wells February 2011 Mark Unruh Installed four horizontal LNAPL recovery wells at a 40 acre tank farm at the Pt. Loma Naval Base. These are likely the longest environmental wells installed to date, with lengths up to 1,810 feet. The wells, installed beneath existing 5M gallon tanks and tank construction projects, were up to 100 feet deep, and most had compound curvatures (a combination of horizontal and vertical curves) to achieve the proper horizontal alignment and vertical profile. A gyroscope steering tool was used for navigation and steering on the project, eliminating any requirement for surface access above the bore path while drilling, and assuring accurate placement of the well. The well casings were six-inch diameter stainless steel. DTD was selected for this project after they had successfully installed a 900 foot well at the site in 2007. That well was in continuous operation since its installation; DTD redeveloped and rehabilitated the well while on site for the drilling operations. _____________________________________________________________________ PAGE 9 _____________________________________________________________________ Earth Tech / AECOM Edwards Air Force Base Injection Well 2007 and 2010/2011 Karl Eggers – (562) 951-2000 DTD designed and installed multiple DNAPL treatment wells, at depths ranging up to 50 feet, and lengths exceeding 1000 feet. For this project, DTD employed a new, proprietary (patent pending) technology that enables the placement of the well casing through the drill rods, ensuring that the well screen is properly placed even in soil or rock materials that are prone to collapse or caving in an open bore. The wells were installed in lake (playa) sediments, that were locally cemented tightly by calcium carbonate (caliche) deposits. _____________________________________________________________________ Environmental Partners, Inc. Pasco Landfill Directional Soil Sampling March-May 2011 Adam Morine – (425) 889-4747 DTD collected more than three dozen undisturbed soil samples in bores more than 600 feet long beneath a capped, decommissioned landfill. More than a half mile of drilling was completed to obtain the full suite of samples. Passive interference from buried, mixed waste required the use of a custom-built, high-powered subsurface locating sonde in order to obtain a usable signal for navigation and steering. The project also required the redesign of soil samplers in the field to assure adequate sample recovery. _____________________________________________________________________ Environmental Technology Initiatives Prague, Czech Republic, 1997 Buenas Aires, Argentina PRC Environmental/U.S. EPA Mark Evans (703) 287-8811 Prague DTD was selected as one of fifteen firms from a nation-wide search to demonstrate an innovative remediation technology at a refinery site outside of Prague in the Czech Republic. Over 150 firms competed for the opportunity to demonstrate their technologies. The objective of the project was to install a horizontal soil vapor extraction well in an area of known contamination. DTD teamed with a group of U.S. and Czech manufacturers to demonstrate the drilling technology, vapor extraction technology, and a sampling technology. The well was installed as planned at the site, despite changed conditions in the soil and severe logistical difficulties. The well exceeded our anticipated contaminant load for PAGE 10 the vapor extraction system and demonstrated to the Czech engineers the feasibility of using horizontal wells for soil remediation. Buenos Aires DTD was again selected to demonstrate horizontal remediation systems to engineering firms in South America. DTD teamed with Vermeer Underground to present a full range of drilling technologies to over 300 engineers and planners as part of this EPA sponsored demonstration.
