**Richard Hetherington, B.S, CEO and Shareholder**

Richard Hetherington, the founder of TRI, possesses a B.S. Degree in Education, with a major in Biology and a minor in Chemistry. He began his career as a public school teacher and taught General Science at the middle school level in the Washington, D.C. Public School System. He left the teaching profession to pursue a career in the business world, gaining extensive experience in the design and development of technology based academic products when he joined IBM's Education Division in 1970. Over the past 25 years, Mr. Hetherington has personally conceptualized, designed, developed and marketed a number of successful technology-based products for the educational field. For example, in 1980, he conceptualized and developed an on-line, integrated administrative system for the Montgomery County, Maryland Public School System. In 1985, his firm developed one of the first intelligent courseware authoring systems using voice recognition and artificial intelligence within its instructional methodology.

In 1993, Mr. Hetherington's company negotiated a Cooperative Research and Development Agreement (CRADA) with the Department of Defense's foreign language laboratory. The contractual effort concerned the development of an automated method to teach survival language skills to government employees who were assigned overseas. During this period, his company developed immersion courses in Spanish, French, Russian and Arabic to enable students to achieve a "survival" level of competency in as little as 50 hours of independent study. This claim was verified by George Mason University's Language department, who concluded that students who worked independently in EXITO, his firm's Spanish language program for a 50-hour period, showed a level of proficiency equal to an entire year in a traditional college language course. Over a two year period, Mr. Hetherington successfully sold this product to more than 300 school systems nationwide. In 1995, he sold the rights to this product to Broderbund Software.

In 1997, Mr. Hetherington created Educational Options, Inc., a firm involved in the creation of a web based instructional system for credit recovery. Over the past 13 years, this product has been installed in more than 1,700 schools across the nation and used by hundreds of thousands of students to obtain high school credits. 98% of these clients have continued to renew their yearly license, some for as long as 13 years. This product was sold to others in a multi-million dollar buyout that enabled Mr. Hetherington to concentrate his efforts in creating STATIS and PASS, Teacher Resources Inc.'s new classroom based instructional support system.

### The STATIS© Classroom Module

STATIS© is a hybrid based instructional system that provides technology based support to both teacher led instruction and independent study. Within the classroom, teachers can use our STATIS© INSTRUCTIONAL SUPPORT SYSTEM to deliver its pre-written instructional, assessment, and remedial content designed to one group of students, while two other groups are studying independently, on-line within either remedial or accelerated instructional content.. Through this use of automation, the clerical aspects of a teacher’s instructional program are reduced by as much as 75%, thus allowing them to concentrate their efforts on the delivery of instruction and ensuring that students have mastered the content and are prepared for end-of-year tests.

STATIS© contains more than 1,500 pre-written lesson plans and 1,500 corresponding independent study lessons for Mathematics, Language Arts, Science, and Social Studies subjects for grades 6 through 9 that are aligned to the Common Core standards and the Virginia SOL. Because each of the 1,500 lessons plans contains a set of formative assessment test questions, a formative assessment test is instantly available for student use after the instruction is delivered by the teacher. The automation of this instructional and assessment process completely eliminates the need for paper, pencils, answer sheets, and scanning devices. Students answer test questions using our proprietary, low cost tablets and receive instant feedback of their results. Students who fail this formative assessment test will receive a targeted remedial lesson that can be studied in school or at home for remedial purposes.

The results for each student on these formative assessment are automatically recorded in the student grade book and graphically shown in colors on the teacher’s instructional calendar that STATIS© has created for them automatically. This calendar will enable supervisory personnel to “see-at-a-glance” how each teacher and student are performing because student results are collectively shown for every instructional session delivered by each teacher.

#### AUTOMATED GRADING, DIAGNOSTICS, REMEDIATION, AND REPORTING

Teachers will never have to create a lesson plan, create, grade, and diagnose student results, as all of this is automatically provided by STATIS©. At the end of each unit of instruction, (a unit mat contain as many as 4 lessons), STATIS will automatically provide teachers with a list of all formative test questions for which students had problems answering. After holding a remedial seminar to discuss these question, STATIS© automatically creates and delivers a SUMMATIVE assessment test that includes these missed questions.

#### INSTANT FEEDBACK OF STUDENT RESULTS

Students use the STATIS© hand held tablets to answer these questions. Their use will further eliminate the need for paper, pencils, bubble charts, and scanning devices in every classroom and provide real-time feedback to both teachers and students.

#### PLANNING - CREATE REVIEW TEST AND RECEIVE REMEDIAL HELP

It is important to know that throughout the instructional process, students are given multiple opportunities to demonstrate mastery of the content and to return to any place in the curriculum to obtain remedial help. Students and their parents can even revisit past years to determine if there were any areas in the curriculum where help was needed but not mastered. By simply clicking on the lesson they wish to revisit, students can instantly receive remedial help. Help is just a few clicks away.

Teachers work hard every day, and STATIS© simplifies the process greatly by managing the instructional lessons, remedial instruction, and diagnostic tests, as well as the grading. Teachers use the STATIS report module to easily determine the academic status of each student in their classes with greater certainty and less effort. Teachers can easily validate their own instructional activities and review with their students the precise areas where help is needed.

### K12 COURSEWARE

The following Mathematics, Language Arts, Science, and Social Study subjects have been placed within STATIS, Teacher Resource Inc.’s on-line, self-study based delivery system. This library of on-line instructional content contains a year-long set of teacher lesson plans, assessment tests, and remedial instruction.

The above content provides on-line instruction for grade levels 1-12 for all of the above subjects. Each of these subjects contains a teacher lesson plan, diagnostic assessment test questions, and remedial instruction. We also stress that the use of our mathematics curriculum does not require textbooks as each lesson contain a comprehensive on-line video based instructional lesson. STATIS will constantly monitor a student’s progress through the content and will not allow them to move forward until mastery has been demonstrated

Our delivery platform, the STATIS instructional support system currently contains a total of 33 subjects for use in grades 6-12.

These subjects can be quickly and easily combined by teachers to create new integrated subjects, such as an integrated Math and Language Arts program for students with special needs. When new subjects are required, our experience is that we can create an entirely new subject from scratch at a cost of approximately $7,000 for a complete subject consisting of approximately 50 to sixty lessons that are complete with automated diagnostic assessment. All of the above on-line courses will align to the Common Core standards adopted by your state. These subjects are:
