PART I

Item 1. Business

CHAD Therapeutics, Inc., a California corporation (“CHAD” or the “Company”) was organized in August 1982 to develop, produce, and market respiratory care devices designed to improve the efficiency of oxygen delivery systems for both home and hospital treatment of patients who require supplemental oxygen. The Company introduced its first respiratory care device in the market in June of 1983 and has introduced additional respiratory care devices in subsequent years.

Pulmonary Disease and Oxygen Therapy

The Company was organized to pursue the development and marketing of devices that improve the efficiency of systems used to administer oxygen to patients requiring supplemental oxygen. These are primarily patients suffering from chronic obstructive pulmonary diseases.

Chronic obstructive pulmonary diseases (COPD) are progressive, debilitating conditions that affect millions of Americans, severely limiting their activities and shortening their lives. Such conditions, which include chronic bronchitis, emphysema, and severe asthma, decrease the capacity of the lungs to oxygenate the blood. To make up for this deficiency, it is common medical practice to administer supplemental oxygen (usually on a 24 hours per day basis) in an amount sufficient to increase blood oxygenation to near normal levels.

According to the National Heart, Lung and Blood Institute of the National Institutes of Health (NIH), COPD represents the fourth leading cause of death in the United States and is predicted to be the third largest cause of death by 2020.

The American Lung Association reported that in 2004 there were 11.4 million Americans suffering from COPD. This report also notes that in 2004 the annual cost to the nation for COPD in health care and indirect costs was estimated to be $37.2 billion.

Although precise data are not available, various individual and institutional sources and reports estimate that there are more than one (1) million home care patients receiving supplementary administration of oxygen. Medicare, which accounts for about 60% of home oxygen providers’ revenues, spent approximately $1.8 billion in 2002 for home oxygen, according to a report by the Centers for Medicare and Medicaid Services Office of Actuary. This represented a 13% increase over the previous year, according to the report.

Chronic obstructive pulmonary diseases are also prevalent in other countries, particularly in some European nations and the Far East, where the incidence is higher than in the United States. We believe the potential international market for home oxygen is expected to grow to 150% of the U.S. market over the next five to ten years.

The primary oxygen supply options for home patients are concentrators that concentrate oxygen from the ambient air (85-90%), and reservoirs containing liquid oxygen (10-15%). Cylinders containing compressed gaseous oxygen account for less than one percent (1%).

Standard oxygen delivery systems are characteristically inefficient, permitting over 67% of the oxygen supply delivered to the patient to be wasted, primarily because the oxygen is administered steadily to the patient, even while he is exhaling. Since the normal breathing cycle consists of an exhalation period that is approximately twice as long as the inhalation period, at least two-thirds (2/3) of

the oxygen from this continuous flow system is wasted. Furthermore, it is generally accepted that the oxygen breathed in during the first one-third (1/3) of the inhalation period provides most of the oxygenation benefit to the patient.

Currently Medicare provides a prospective flat-fee monthly payment for home oxygen services based solely on the patient’s prescribed oxygen requirement and disregards modality, the type of system in use. In accordance with the federal budget reconciliation bill approved by the Senate in February 2006, title to oxygen equipment transfers to the beneficiary after 36 months. Consequently, with the incentive to operate efficiently, inexpensive concentrators have grown in popularity because of their low cost and less frequent servicing requirements. At the same time, interest in oxygen conserving devices, which can extend the life of oxygen supplies and reduce service calls by providers, has heightened. There is also a separate fixed allowance from Medicare for patients who need to be mobile and therefore require portable oxygen systems.

In November 2003 Congress enacted the Medicare Improvement and Modernization Act, which had and will continue to impact reimbursement for home oxygen over the next several years. The new legislation will result in continued pressure on home care providers to reduce the cost of providing home oxygen services as it mandated that the monthly fee that home care providers receive will be subject to competitive bidding. This will first be implemented in ten (10) major markets on April 1, 2008. In January of 2007, Medicare implemented a new reimbursement category for transfilling systems, like the Company’s TOTAL O₂Delivery System, which may improve the marketability of these devices.

While these cost pressures have intensified, mobility has increased in importance as the treatment of pulmonary patients has moved away from hospitals and into home care. Also, the American Lung Association has advised that, to reduce and control symptoms, pulmonary patients should live a healthy lifestyle that includes exercise. Maintaining quality of life and compliance with prescribed exercise programs require that the patient be as mobile as possible, thereby increasing the demand for portable oxygen equipment.

CHAD’s Products

Since its inception, the Company has recognized the need for more efficient oxygen delivery systems and has pursued the development and marketing of devices that are designed to conserve oxygen. The benefits of such improvements include substantial cost savings for the home care provider, as well as increased mobility for ambulatory patients who require portable oxygen supplies. These devices extend the life of oxygen supplies and make possible more compact and longer lasting portable systems, thereby improving the quality of life for home oxygen patients.

OXYMIZER^® and OXYMIZER Pendant Oxygen Conserving Devices. In June 1983 the Company began marketing its first product, the OXYMIZER disposable oxygen conserving device, a unique, patented, disposable device developed to provide up to four-to-one (4:1) savings of oxygen as compared to continuous flow systems when used with any oxygen supply source.

The OXYMIZER device contains a collapsible reservoir that captures incoming oxygen delivered during expiration and prevents its waste. The oxygen captured in this reservoir is then inhaled by the patient during the first instant of his next inspiration. Thus the OXYMIZER device both conserves oxygen and provides the patient with an extra rich supply of oxygen at the beginning of the inhalation period when it can be most effectively utilized.

Extensive clinical testing and trials over the past 23 years have repeatedly demonstrated that patients using the OXYMIZER device are able to achieve equivalent blood oxygenation levels while using significantly less oxygen. There have been more than 32 clinical evaluations from institutions worldwide that have confirmed the efficacy and oxygen savings of the OXYMIZER devices.

The greater efficiency provided by these devices over standard oxygen delivery systems also permits home health care patients to achieve greater mobility by enabling them to use smaller portable cylinders or by obtaining two (2) to four (4) times the life from standard sized portable cylinders.

For home oxygen providers, the disposable OXYMIZER devices afford the cost advantages of oxygen conservation without capital investment in expensive equipment. In addition, the OXYMIZER devices can be utilized to achieve higher flow setting equivalencies for standard oxygen concentrators.

In hospitals, the OXYMIZER devices are used for maintenance of certain patients requiring higher flow levels of oxygen without having to resort to uncomfortable oxygen masks.

The Company is pursuing a marketing strategy that emphasizes the cost savings, efficiencies, and level of patient comfort associated with the use of the OXYMIZER devices. See “Marketing” and “Competition.”

The OXYMIZER Pendant device is similar to the OXYMIZER device except that its reservoir is located in a “pendant” that hangs over the patient’s chest rather than under the nose. The OXYMIZER Pendant has a more traditional appearance than the OXYMIZER. The Company began marketing the OXYMIZER Pendant in August 1984.

OXYMATIC^® Electronic Oxygen Conservers. The Company began marketing the OXYMATIC conserver in March 1986. This product is a small electronic device designed for use with portable oxygen systems. The OXYMATIC conserver electronically senses the optimal moment in the breathing cycle for delivery of oxygen and at that moment releases a very brief pulse of oxygen to the patient. The OXYMATIC conserver concentrates the administration of oxygen during the first one-third (1/3) of the inhalation phase, when oxygen is most efficiently utilized. There have been at least 12 controlled clinical trials and studies of patient groups using the OXYMATIC conserver, all of which have confirmed its efficacy and efficiency.

In July 2000 the Company introduced the first of the OXYMATIC 400 series of conservers. Additional models were added to this line in January and March of 2001. This new line of conservers was designed to capitalize on the proven reliability and efficiency of the Company’s previous models. In addition, features and options were added to create state-of-the-art conservers that would give home care providers a wide choice of products to service their patients’ individual needs and preferences. These new conservers include a built-in regulator and expanded flow rates that provide average savings of five-to-one (5:1) over continuous flow oxygen systems.

In November 2001 the Company introduced the SEQUOIA OXYMATIC line of conservers. These conservers utilize the same electronic features as the OXYMATIC 400 series conservers but do not contain a built-in regulator.

LOTUS Electronic Oxygen Conservers. The Company received clearance from the Food and Drug Administration (FDA) to market the LOTUS Electronic Oxygen Conserver in October 2004 and began shipment of the device in November 2005. The LOTUS weighs less than one (1) pound and is offered with or without a breath-sensing alarm. It also offers additional liter flow settings and an extended battery life of up to four (4) months of normal usage on two (2) AA-size batteries.

CYPRESS OXYPneumatic^® Conservers. In July 2002 the Company began marketing the CYPRESS pneumatic conserver, which allowed the Company to compete in the pneumatic segment of the conserver market for the first time. This device incorporates no electronic parts, thus eliminating the need for batteries. It is lightweight, small and allows the use of a standard, single-lumen cannula, unlike

many other pneumatic conservers that require special cannulas. The CYPRESS conserver provides flow rates from one (1) to six (6) liters per minute and oxygen savings greater than three-to-one (3:1) over continuous flow oxygen.

The OXYMATIC electronic and CYPRESS pneumatic conservers extend the length of time the contents of the cylinders will last over continuous flow oxygen systems. They provide ambulatory patients with greater mobility and less weight. The Company believes these systems offer a superior alternative to commonly used liquid oxygen systems for mobile patients and are more cost effective for home care providers to supply.

BONSAI Pneumatic Conservers. In April 2007 the Company announced the new BONSAI pneumatic conserver. The BONSAI conserver incorporates a number of new features, including lightweight design (less than 10 ounces), conserving ratios of up to six-to-one (6:1), eight (8) settings and an adjustable continuous flow feature. The Company received FDA Clearance to market this new device in May 2007 and anticipates commencing shipments in June or July 2007.

Sales of electronic and pneumatic conservers accounted for approximately 68%, 70%, and 73% of the Company’s sales in 2007, 2006, and 2005, respectively.

SAGE Oxygen Therapeutic Device. In May 2004 the Company received clearance from the FDA to market its new SAGE Oxygen Therapeutic Device. The SAGE device is the first in a planned family of oxygen therapeutic devices that use the Company’s proprietary technologies to sense a patient’s movements and automatically adjust the rate of oxygen delivery to reduce the risk of desaturation as activity increases. The SAGE device combines the industry’s first truly dynamic, patented delivery technology with the proven oxygen sensor technology in the Company’s OXYMATIC 400 series conserver. As a result, the device addresses the common problem of oxygen desaturation, which causes a patient to feel weak and out of breath when activity increases, yet it still maximizes patient ambulatory capability.

OXYCOIL^® Coiled Oxygen Tubing. In January 1986 the Company began marketing the OXYCOIL coiled oxygen tubing, a device which replaces the standard supply tubing for the OXYMIZER devices, the OXYMATIC conservers or conventional nasal cannulas. The OXYCOIL tubing is a convenience and a safety device that can be used with any oxygen system to help keep the supply tubing out of the patient’s way, thus minimizing the tripping and tangling problems associated with standard supply tubing.

TOTAL O₂^® Delivery System. In January 1998 the Company began marketing the TOTAL O₂Delivery System. This system provides stationary oxygen for patients at home, portable oxygen including an oxygen conserving device for ambulation, and a safe and efficient mechanism for filling portable oxygen cylinders. The TOTAL O₂Delivery System was designed to provide home care providers with a more cost effective means to provide home oxygen services while at the same time providing the patients with a higher quality of service. This can be accomplished as the home care provider will no longer be required to make regular monthly service calls to deliver full portable cylinders, and the patient will no longer be dependent on the provider for those deliveries to obtain full cylinders.

Initial sales of the TOTAL O₂ system were adversely affected by several factors, including the overall home oxygen market climate and home care providers’ reluctance to invest in the higher cost of the TOTAL O₂ system to achieve the lower monthly operating costs it affords. Recent changes in home oxygen reimbursement appear to be causing home care providers to examine their operating costs more carefully, which should have a positive impact on sales of the TOTAL O₂system. No assurances can currently be given regarding the level of success the Company may achieve with the TOTAL O₂ system. See Outlook: Issues & Risks — New Product in the Company’s Annual Report to Shareholders.

The technology for each of the devices described above has been licensed from the inventors thereof, with the exception of the CYPRESS OXYPneumatic and LOTUS conservers, which belongs to the Company. The Company has acquired exclusive licenses to manufacture and market the OXYMIZER devices, the OXYMATIC conservers, the SAGE device, the OXYCOIL tubing, and the TOTAL O₂ system. See “Licensing and Related Agreements.”

Sales of the TOTAL O₂ system accounted for approximately 9.4%, 10.7%, and 9.6% of the Company’s sales in 2007, 2006, and 2005, respectively.

Other Products. The Company also offers a variety of ancillary products that support the principal oxygen conserving products. These include oxygen cylinders of various sizes and compositions, regulators, cannulas and connecting tubing, and assorted carrying bags. In addition, with a field sales force of manufacturer’s representatives and direct sales representatives covering the entire United States (see “Marketing”), the Company will utilize this team as part of a strategy to market and sell additional products that are targeted for the Company’s current customer base, the home care provider.

Products Under Development

It is the Company’s objective to continuously improve and add to its oxygen conserving and related products. During the fiscal years ended March 31, 2004 and 2003, the Company entered into contracts with outside vendors to develop products in the home oxygen market and sleep disorder market. Development efforts continue on these products, some of which have begun pre-clinical testing. No assurance can be given that any products developed pursuant to these contracts will be successfully marketed or that the Company will ever derive significant revenues or earnings from the sale of such products.

Research and Development

For the year ended March 31, 2007, 2006 and 2005, the Company expended approximately $1,466,000, $1,574,000, and $1,473,000 respectively, on research and development and has expended approximately $12,132,000 since its inception in August of 1982. The Company operates in an industry that is subject to rapid technological change, and its ability to compete successfully depends upon, among other things, its ability to stay abreast or ahead of new technological developments. Accordingly, the Company expects to expend increasing amounts for the development or acquisition of new products or the improvement of existing products. In the next fiscal year the Company expects to spend approximately $1,754,000 on several projects. The Company conducts research and development internally and also utilizes the services of outside firms and consultants for its research and development activities.

Licensing and Related Agreements

The Company has entered into license agreements (the “Inventor’s License Agreements”) with Brian L. Tiep, M.D., Robert E. Phillips, and Ben A. Otsap, the inventors of the OXYMIZER device (the “Inventors”), with respect to that device and each of the additional oxygen conserving devices developed by them.

Pursuant to the Inventor’s License Agreements, the Inventors granted to the Company an exclusive license (with the right to grant sublicenses) to manufacture, use, and sell such devices. Through September 2003, the Inventor’s License Agreements provided that the Company pay royalties to the Inventors on the net proceeds of sales of the device covered by the agreement at the rate of six percent (6%) on amounts up to ten (10) million dollars and three percent (3%) on amounts of ten (10) million dollars or more. As of September 2003, no further royalty payments are due. The Company is obligated to prosecute and defend, at its own expense, any infringement suits related to manufacture or sale of each device covered by any such agreement. Each Inventor’s License Agreement continues until the expiration

of the last to expire of any patent covering the related device or, if no patent is issued, for 17 years.

The Company has also entered into a license agreement (the “Carleton License Agreement”) with the Life Support Division of Carleton (formerly Litton Life Support) for the TOTAL O₂ Delivery System. Pursuant to the Carleton License Agreement, the Licensors granted to the Company an exclusive license (with the right to grant sublicenses) to manufacture, use, and sell such device in the health care market. The Carleton License Agreement provides that the Company pay royalties to the Licensor on the net proceeds of sales of the device covered by the agreement at the rate of seven percent (7%) and requires minimum annual royalties of $100,000, $300,000, and $500,000 in 1999, 2000, and subsequent years, respectively. The Carleton License Agreement continues until the expiration of the last to expire of any patent covering the related device or until the Company ceases use of the licensed technology. The Licensors may terminate the Carleton License Agreement at an earlier date if the Company is in arrears for 30 days on any royalty payment or if the Company defaults in performing any other material obligation of the agreement and fails to cure such default within 30 days.

The Company has also entered into a license agreement (the “Phillips and Otsap License Agreement”) with Robert E. Phillips and Ben A. Otsap for the SAGE Oxygen Therapeutic Device. Pursuant to the Phillips and Otsap License Agreement, the Licensor grants to the Company an exclusive license (with the right to grant sublicenses) to manufacture, use, and sell such devices in the health care market. The Phillips and Otsap License Agreement provides that the Company pay royalties to the Licensor on the net proceeds of sales of the device covered by the agreement at the rate of three percent (3%) for unit sales up to 1,499 units, four percent (4%) for unit sales from 1,500 to 1,999 units per month, five percent (5%) for unit sales from 2,000 to 2,499 units per month and six percent (6%) for unit sales of 2,500 or more per month. The agreement also requires minimum annual royalties of $15,000 in the first year after FDA clearance is received to market the product and $30,000 per annum thereafter. The Phillips and Otsap License Agreement continues until the expiration of the last to expire of any patent covering the related devise or until the Company ceases use of the licensed technology. The Licensors may terminate the Phillips and Otsap License Agreement at an earlier date if the Company is in arrears for six (6) days on any royalty payment or if the Company defaults in performing any other material obligation of the agreement and fails to cure such default within 30 days.

Manufacturing and Sources of Supply

The Company tests and packages its products in its own facility and performs some manufacturing operations on certain products. Some manufacturing processes are conducted by other firms and the Company expects to continue using outside firms for certain manufacturing processes for the foreseeable future. All outside manufacturing is conducted under the supervision and control of the Company and with tooling provided by the Company.

Pursuant to a written agreement, the Company purchases finished units of the OXYMIZER devices from a supplier in Hong Kong. The Company believes that other injection molding facilities would be available in the event of a termination of this arrangement.

Production of the OXYMATIC 300 series, 2400, and 400 series conservers, the LOTUS, the CYPRESS and BONSAI pneumatic conservers, and the SAGE Oxygen Therapeutic Device are being handled internally with only a portion of the electronic assembly for electronic conservers being subcontracted outside the Company. The Company is currently subcontracting with two (2) electronic assembly facilities and believes that other facilities would be available in the event of an interruption of supply from the existing facilities.

Production of the TOTAL O₂ system is being handled internally with a number of subassemblies being subcontracted outside the Company. The Company believes that there are alternate sources of supply for these subassemblies, including internal manufacturing as production quantities increase.

The Company is not aware of any shortages of materials necessary for the manufacture of its products. The Company provides customers the right to return merchandise for credit and requires payment within a time frame consistent with industry standards. The Company provides warranties for certain of its products based on industry standards and accrues for the estimated expenses associated with those warranties based on the best information available, primarily historical claims experience.

The Company has received ISO 13485 certification for its manufacturing facility based on criterion developed by the International Organization for Standardization, a quality standards organization with headquarters in Geneva, Switzerland. The Company has also received authorization for the same facility under the European Union’s Medical Devices directive, to affix the “CE Mark” to the Company’s products marketed throughout the world. The primary component of the certification process was an audit of the facility’s quality systems conducted by an independent agency authorized to perform conformity assessments under ISO guidelines and the Medical Devices Directive.

Marketing

The Company’s products are designed to reduce the cost of health care while maintaining or enhancing the therapeutic benefits to the patient and improving the user’s quality of life. The Company’s marketing efforts have focused primarily on providing home oxygen suppliers with products that they can utilize to increase their revenues and provide a better quality of care at less cost.

Home care providers have reportedly increased their revenues by assembling small portable systems incorporating the Company’s OXYMATIC electronic conserver or CYPRESS pneumatic conserver as a vehicle to attract new and additional patients to their business. The Company believes these lightweight, long-lasting, portable systems have both high professional and patient acceptance that allows the supplier promoting these products to attract new and additional customers.

A large portion of home oxygen patients is covered by Medicare or other government programs. Since June 1989 home oxygen suppliers have been reimbursed on a fixed, monthly-fee basis by Medicare. The monthly reimbursement amount does not vary with either the type of oxygen delivery equipment provided or the amount of oxygen supplied. Since monthly, per-patient revenues are fixed, home oxygen suppliers can only increase their per-patient profitability by reducing costs. The Company’s oxygen conserving products and TOTAL O₂ Delivery System allow these suppliers to decrease their costs while providing their patients with improved therapeutic benefits and quality of life.

While the home respiratory care provider remains the primary focus of the Company’s marketing efforts, this focus has been augmented by a major effort to increase professional awareness. Promotional programs target respiratory care physicians, nurses, and therapists.

The Company markets its products directly to home oxygen suppliers throughout the U.S. The Company currently has a Senior Vice President of Sales & Marketing, two (2) Regional Vice Presidents of Sales, a manager of sales administration, an art and media manager, and four (4) in-house sales and customer service representatives who are in regular and frequent proactive telephone sales contact with customers and potential customers. In addition, the Company has a field sales force of direct sales representatives and independent manufacturer’s sales representatives to handle direct selling to customers. This field sales force is currently comprised of five (5) direct sales representatives and 15 manufacturer’s sales representatives with coverage throughout the United States. The Company also utilizes direct mail, trade show attendance, trade advertising, and a web site to promote the benefits of its products to home care providers. Additionally, the Company actively seeks to increase professional awareness of its products through professional advertising and participation in professional meetings.

Home oxygen therapy markets outside the United States are, in most cases, at a much earlier stage of development. In many countries, these patients are cared for in institutional settings. As the trend develops to move patients into home care, opportunities for the Company’s products should increase. Sales of conservers in Europe, Canada, and Japan have become an important part of the Company’s business. Based on industry market research projections, the Company expects the international market to increase to 150% of the U.S. potential over the next five (5) to ten (10) years.

The Company has entered into exclusive distributorship agreements in Germany, Japan, and several other countries. The Company also has non-exclusive distributors in many other countries.

Sales outside of the United States subject the Company to certain risks, including those involving political and economic factors, interruption of shipments of products, currency fluctuations and devaluations, and governmental restrictions and regulations.

Customers, Backlog and Orders

The Company presently has an active list of over 4,000 providers and hospital customers. Based upon information developed from various lists the Company believes that there are approximately 7,000 to 8,000 home oxygen providers and 3,000 general hospitals in the United States that are potential customers or customer sources for the Company. Of these 7,000 to 8,000 home care providers, approximately 48% are represented by three (3) major national chain accounts. One (1) national chain customer accounted for 41%, 36%, and 36% of net sales during 2007, 2006, and 2005, respectively, and one (1) other chain accounted for 11% of sales in 2005. One non-chain customer accounted for 11% of sales in 2006.

At March 31, 2007, the Company had no backlog of orders for any of its products. The Company presently endeavors to maintain sufficient inventory to ship all of its products immediately upon receipt of orders. The Company believes that maintaining such levels of inventory is necessary to meet the requirements of its customers.

Competition

Competition in the Company’s market has increasingly focused upon pricing, rather than product features. The Company is aware of several demand-valve, electronically controlled devices currently being marketed. Of these devices, those that have been the principal competitors of the OXYMATIC conserver in the past were targeted primarily to a specific segment of the market — liquid oxygen usage. Several companies, including Caire Inc. and Puritan Bennett, market small (3.4 to 5.5 pounds) portable liquid oxygen systems incorporating simple oxygen conserving devices that double the useful life of these systems. Some of these companies have substantially greater marketing and financial resources than the Company. However, these units are more expensive than systems utilizing the OXYMATIC conservers and still require the supplier to make frequent and costly oxygen deliveries. The Company does not know the levels of sales achieved by the companies marketing these systems.

Several of these competitors are now marketing conservers in direct competition with the Company’s OXYMATIC electronic and CYPRESS pneumatic conservers. Some of these conservers provide only two-to-one (2:1) to three-to-one (3:1) savings ratios compared to continuous flow. As a result, these units, while weighing about the same as the OXYMATIC conserver, provide only one-third (1/3) or one-half (1/2) as much ambulation time. In addition, the Company is aware of two (2) companies marketing oxygen conserving devices that claim similar oxygen savings ratios as the OXYMATIC conserver. The Company believes that some of these competitors have been able to offer their oxygen conservers as part of a bundle of products with perceived pricing advantages over the Company’s products. The Company does not know the level of sales achieved by these companies.

There are several other types of portable oxygen systems which compete with the Company’s OXYMATIC conservers but do not utilize oxygen conserving devices. Aluminum and steel oxygen cylinders with continuous flow regulators are utilized by some oxygen suppliers as portable systems. Although they do provide users with some portability, their size and bulk limit their use by patients who need or want to be truly ambulatory. The most commonly used of these cylinders is approximately three (3) feet high, weighs over 20 pounds, and provides an average patient with less than five (5) hours of oxygen. These systems are enjoying some level of success due to their lower unit-price advantage. The OXYMATIC electronic and CYPRESS pneumatic conservers allow the use of smaller, lighter cylinders and thus provide greater mobility.

Until the availability of portable systems utilizing the OXYMATIC conservers and the previously cited changes in Medicare oxygen reimbursement, liquid oxygen was the modality of choice for truly mobile users. Portable liquid oxygen systems that weigh 3.4 to 10 (ten) pounds, provide an average patient with six (6) to eight (8) hours of oxygen, compared to the smallest portable system which weighs 4.5 pounds and provides an average patient with 7.3 hours of oxygen. These systems are more costly than systems utilizing the OXYMATIC conservers and require frequent and expensive (often weekly) deliveries of bulk liquid oxygen to the patient’s home. In addition, the patient must remain within range of the base unit for refilling, unlike with the systems utilizing the OXYMATIC conservers with which a patient can take as many cylinders as needed to provide the amount of time necessary to be away from the base unit.

The Company is aware of one (1) combination oxygen concentrator and refilling station being marketed in competition with the TOTAL O₂ system. This system is larger and heavier and does not contain some of the integrated features found in the TOTAL O₂ system. In addition, another competitor has recently introduced a refilling station that also competes with the TOTAL O₂ system. These competitors have substantially greater financial and marketing resources than the Company and have used these resources to aggressively market their products. The Company does not know the level of sales achieved for these systems by the competition.

Patents and Trademarks

The Company regards the products that it develops or licenses and its manufacturing processes as proprietary and relies on a combination of patents, trademarks, trade secret laws, and confidentiality agreements to protect its rights in its products. U.S. patents have been issued covering the original OXYMATIC conserver, the Lotus conserver, the CYPRESS OXYPneumatic conserver, the TOTAL O₂ Delivery System, and the SAGE Oxygen Therapeutic Device. A number of foreign patent applications pertaining to the Company’s activities have also been issued.

The Company pursues a policy of obtaining patents for appropriate inventions related to products marketed or manufactured by the Company. The Company considers the patentability of products developed for it to be significant to the success of the Company. To the extent that the products to be marketed by the Company do not receive patent protection, competitors may be able to manufacture and market substantially similar products. Such competition could have an adverse impact upon the Company’s business.

There can be no assurance that patents, domestic or foreign, will be obtained with respect to the Company’s products, or that, if issued, they will provide substantial protection or be of commercial benefit to the Company. In addition, the patent laws of foreign countries may differ from those of the United States as to the patentability of the Company’s products and processes and, accordingly, the degree of protection afforded by foreign patents may be more or less than in the United States.

In the United States, although a patent has a statutory presumption of validity, the issuance of a patent is not conclusive as to such validity or as to the enforceable scope of its claims therein. The validity and enforceability of a patent can be attacked by litigation after its issuance by the U.S. Patent and Trademark Office. If the outcome of such litigation is adverse to the owner of the patent in that the patent is held to be invalid, other parties may then use the invention covered by the patent. Accordingly, there can be no assurance that patents with respect to the Company’s products, if issued, will afford protection against competitors with similar products, nor can there be any assurance that the patents will not be infringed upon or designed around by others.

Through patent searches, contacts in the industry, and representations and indemnities received from licensors and development partners, the Company seeks to ensure that its products do not infringe on the intellectual property rights claimed by others. However, interpretation of the scope and validity of existing patent rights may differ, and no assurance can be given that the Company products will in all cases not infringe on the rights of others. Moreover, any dispute regarding potential infringement may require substantial management and financial resources to defend.

The Company has obtained U.S. registration for the trademarks “OXYMIZER,” “OXYMATIC,” “LOTUS,” “OXYPneumatic,” “CHAD,” “OXYCOIL,” and “TOTAL O_2.” A series of foreign applications to register the trademark “OXYMIZER” in a number of countries of commercial interest to the Company have been filed.

Governmental Regulation

The commercialization of the conservers and trans-fill devices is subject to the Federal Food, Drug and Cosmetic Act (the “Food and Drug Act”) and to regulations issued thereunder. The Company anticipates that commercialization of other devices that it intends to market will also be subject to the Food and Drug Act. The Food and Drug Act is administered by the FDA, which has authority to regulate the marketing, manufacturing, labeling, packaging, and distribution of products subject to the Food and Drug Act. In addition, there are requirements under other federal laws and under state, local, and foreign statutes that may apply to the manufacture and marketing of the Company’s products. The Medical Device Amendments of 1976 to the Food and Drug Act (the “Amendments”) and the Safe Medical Device Act of 1990 significantly extended the authority of the FDA to regulate the commercialization of

medical devices. The Amendments established three (3) classifications of medical devices: Class I, Class II, and Class III. With respect to all three (3) classes, the general provisions of the Food and Drug Act prohibit adulteration and misbranding. A medical device may be adulterated if the device is or could be adversely affected by its methods of manufacture, storage, or packaging. A medical device may be misbranded if its labeling is false or misleading or if its labeling does not contain specific information required by law applicable to such type of device. In addition, failure to register a medical device covered under the Food and Drug Act will render it misbranded under the Food and Drug Act.

All manufacturers of medical devices must register with the FDA and list all medical devices produced by them. This listing must be updated annually. In addition, prior to commercial distribution of additional devices, the manufacturer must file with the FDA and receive approval prior to the commencement of such commercial distribution, a notice setting forth certain information about the device, including the classification into which the manufacturer believes it falls.

Class I devices are subject only to the general controls concerning adulteration, misbranding, good manufacturing practices, record keeping, and reporting requirements. Class II devices must, in addition, comply with performance standards as promulgated by the FDA.

The Company has registered with the Bureau of Medical Devices of the FDA as a Medical Device Establishment and with the Department of Health Services of the State of California as a Medical Device Manufacturer. In addition, the Company has developed procedures to comply with FDA standards concerning good manufacturing practices, record keeping, and reporting and is ISO 13485 certified.

The Company has been granted permission by the FDA to market the OXYMIZER and the OXYMIZER Pendant as Class I devices. Permission has been granted to market the OXYMATIC, the CYPRESS OXYPneumatic, the BONSAI pneumatic, the LOTUS Electronic Oxygen conserver, the OXYCOIL, the TOTAL O₂ Delivery System, and the SAGE Oxygen Therapeutic Device as Class II devices.

Employees

As of June 21, 2007, CHAD had 106 full-time employees and four (4) part-time employees with 63 of the Company’s employees engaged in manufacturing and the remaining engaged in marketing, sales, administration, and management. None of the Company’s employees is represented by unions, and the Company believes its employee relations are satisfactory.

Item 1A. Risk Factors.

Our future operating results are subject to a number of material risks and contingencies. Forward-looking statements in this report reflect the Company’s current views and expectations. However, such forward-looking statements are subject to the risks and uncertainties described herein which may cause future operating results to differ materially from currently anticipated results.

Our future results depend upon our ability to successfully introduce new products.

We operate in a market which is subject to continuing technological change. In order to stay abreast of new technological developments, we must continually improve our products. Moreover, there is significant price pressure on our primary product line, oxygen conservers. As a result, in order to mitigate the price pressure on our conservers, we must introduce innovative new products and we intend to expand our product offerings.

There are a number of significant risks involved with new product introductions. Problems encountered in the design and development of new products or in obtaining regulatory clearances to

market the products may impair our ability to introduce any new product in a timely manner. Competitors may leapfrog our development efforts, particularly if our development efforts are delayed.

The commercial success of any new products we do introduce will depend upon the health care community’s perception of such products’ capabilities, clinical efficacy and benefit to patients. In addition, prospective sales will be impacted by the degree of acceptance achieved among home care providers and patients requiring supplementary oxygen. Our prospective customers may be reluctant to try unproven products which we introduce. Our ability to successfully introduce new products in a new market sector such as the sleep disorder market will also be complicated by our lack of experience and our lack of an established reputation in this market. Thus, the success of any new products we may introduce is unpredictable and our future results may suffer if we are unable to successfully introduce new products.

Our operating results, profitability and operating margins have been adversely affected by price pressure on our principal products.

During the past several years, there has been significant price pressure on oxygen conservers and therapeutic devices. Thus, though our unit sales of conservers and therapeutic devices in fiscal 2007 showed a 10.1% decline, revenues from the sales of such products declined by 16.9%. This trend is magnified by the continuing consolidation of the home care industry as national chains typically negotiate for quantity discounts. We expect continuing price pressure on our principal products for the foreseeable future.

We are highly dependent upon a limited number of large customers, which may increase the volatility of our future operating results.

The home health care industry is undergoing significant consolidation. As a result, the market for our products is increasingly influenced by major national chains. Four major national chains accounted for 49% of our sales for the year ended March 31, 2007, up from 43% in the prior year. One customer accounted for 43%, 36% and 36% for the years ended March 31, 2007, 2006, and 2005, respectively. A second customer accounted for 11% of sales for the year ended March 31, 2005. One non-chain customer accounted for 11% of sales for the year ended March 31, 2006. Future sales may be increasingly dependent upon a limited number of customers which increase the risk that our financial performance may be adversely affected if one or more of these customers reduces their purchases of our products or terminates its relationship with us. During the past two years, a significant decline in orders from one national chain contributed to our decline in revenues.

We are dependent upon a single product line, which increases our vulnerability to adverse developments affecting the market for supplementary oxygen.

Although we market a range of products, all of our current products are designed for patients requiring supplemental oxygen. Unlike some of our competitors, we are not a diversified provider of home health care products. As a result, our future performance is dependent upon developments affecting this narrow segment of the health care market. Adverse regulatory or economic developments affecting the market for supplemental oxygen will have a significant impact on our performance.

Changes and prospective changes in the administration of health care may disrupt the market for our products, resulting in decreased profitability.

Approximately 80% of home health care patients are covered by Medicare and other government programs. Federal law has altered the payment rates available to providers of Medicare services. The Medicare Improvement and Modernization Act of 2003 has resulted in several years of reductions in reimbursement for home oxygen. In February 2006, reimbursement procedures were modified again, with a new requirement that ownership of home oxygen equipment be transferred to the patient after 36

months. New proposals related to reimbursement for home health care are routinely introduced in Congress.

As a result, we expect changes in reimbursement policies to continue to exert downward pressure on the average selling price of our products. Moreover, the uncertainty resulting from constant change in reimbursement policies has had a deleterious effect upon our market, causing many home care providers to delay or cut back their product purchase plans as they seek to evaluate the impact of the new policies.

We operate in a highly competitive environment which has contributed to our reduced operating margins.

Our success in the early 1990s drew a significant number of competitors into the home oxygen market. Some of these competitors have substantially greater marketing and financial resources compared with those of the Company. While we believe that our product features and reputation for quality will continue to be competitive advantages, we note that our market is increasingly dominated by price competition. Some of our competitors have successfully introduced lower priced products that do not provide oxygen conserving capabilities comparable to our products. We expect competition to remain keen, with continuing emphasis on price competition for oxygen conservers and therapeutic devices.

If we are unable to stay abreast of continuing technological change, our products may become obsolete, resulting in a decline in sales and profitability.

The home health care industry is characterized by rapid technological change. Our products may become obsolete if we do not stay abreast of such changes and introduce new and improved products. We have limited internal research and development capabilities. Historically, we have contracted with outside parties to develop new products. Some of our competitors have substantially greater funds and facilities to pursue development of new products and technologies. If we are unable to maintain our technological edge, our product sales will likely decline, as will our profitability.

Failure to protect our intellectual property rights could result in a loss of market share.

The success of our business is dependent to a significant extent upon our ability to develop, acquire and protect proprietary technologies related to the delivery of supplementary oxygen. We pursue a policy of protecting our intellectual property rights through a combination of patents, trademarks, license agreements, confidentiality agreements and protection of trade secrets. To the extent that our products do not receive patent protection, competitors may be able to market substantially similar products, thereby eroding our market share. Moreover, claims that our products infringe upon the intellectual property rights of any third party could impair our ability to sell certain products or could require us to pay a license fee, thereby increasing our costs.

Our profitability would be adversely affected if we incur uninsured losses due to product liability claims.

The nature of our business subjects us to potential legal actions asserting that we are liable for personal injury or property loss due to alleged defects in our products. Although we maintain product liability insurance in an amount which we believe to be customary for our size, there can be no assurance that the insurance will prove sufficient to cover the costs of defense and/or adverse judgments entered against the Company. To date, we have not experienced any significant losses due to product liability claims. However, given the use of our products by infirm patients, there is a continuing risk that such claims will be asserted against us.

Our dependence upon third party suppliers exposes us to the risk that our ability to deliver

products may be adversely affected if the suppliers fail to deliver quality components on a timely basis.

While we perform most of our manufacturing internally, some of our products depend upon components or processes provided by independent companies. We expect to continue to use outside firms for various processes for the foreseeable future. From time to time, we have experienced problems with the reliability of components produced by third party suppliers. We do not have any long-term supply contracts that are not readily terminable, and we believe there are alternative sources of supply with respect to all the components we acquire from third parties. Nonetheless, any reliability or quality problem encountered with a supplier could disrupt our manufacturing process, thereby delaying our ability to deliver timely product and potentially harming our reputation with our customers.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

The Company’s offices and manufacturing facilities are situated in premises located in Chatsworth, California, and consist of approximately 55,500 square feet, at a monthly rental fee of $36,000 pursuant to a lease expiring in June 2008. Management believes this facility should adequately handle the Company’s needs for the foreseeable future. The Company does not own any real property and does not anticipate acquiring any in the foreseeable future.

Item 3. Legal Proceedings.

The Company becomes involved in legal proceedings in the ordinary course of business. The Company maintains product liability insurance in an amount it deems customary in the industry for protection of the Company against potential product liability claims. Although the Company believes its product liability insurance is sufficient and no pending legal proceeding poses a material threat, no assurance can be given that pending or future proceedings will not have a material impact on the Company’s financial condition or results of operations.

Item 4. Submission of Matters to a Vote of Security Holders.

Section 16 Beneficial Ownership Reporting Compliance

Under the Federal securities laws, the Company’s directors, its executive officers and any persons holding more than ten (10) percent of the Company’s common stock are required to report their ownership of the Company’s common stock and any changes in that ownership to the Securities and Exchange Commission on Form 3, for an initial report of securities ownership, and on Forms 4 or 5, for reports of changes in security ownership. Such directors, executive officers and ten (10) percent shareholders are also required by Securities and Exchange Commission rules to furnish the Company with copies of all Section 16(a) forms they file. Specific due dates for these reports have been established and the Company is required to report in this Annual Report any failure to file by these dates during the most recent fiscal year or prior fiscal years. Based on the written representations of its directors and executive officers and its ten (10) percent shareholders and copies of the reports that they have furnished to the Company, the Company believes that the Company’s directors and executive officers and ten (10) percent shareholders timely filed all reports required under Section 16(a) in fiscal 2007.

Item 11. Executive Compensation.

Compensation Discussion and Analysis

The following Compensation Discussion and Analysis describes the material elements of compensation for our executive officers identified in the Summary Compensation Table (the “Named Executive Officers”). The Compensation Committee of our Board of Directors is responsible for determining all aspects of the compensation of our Chief Executive Officer (“CEO”). In addition, the Compensation Committee approves performance objectives for our other Named Executive Officers and makes recommendations to the Board regarding the base salary of such Named Executive Officers. The Compensation Committee approves all grants of equity awards to our Named Executive Officers. The Compensation Committee consults with the CEO and the Chairman on all matters of executive compensation. Generally, proposals on executive compensation originate with the CEO and Chairman and are presented to the Compensation Committee for their consideration. The CEO and the Chairman attend most Compensation Committee meetings; however, they are not present when the Compensation Committee considers their individual compensation.

Compensation Objectives

Our principal compensation objectives are to:

•		Attract and retain well-qualified executives

•		Create a performance-oriented environment

•		Strengthen the identification of executive officers with shareholder interests

•		Reward long-term commitment.

We are a small medical device manufacturer operating in a sector of the health care market which is challenged by continuing uncertainty regarding government reimbursement policies. Our industry has also been challenged by continuing price pressure on oxygen conservers and related products. As such, our prospects depend heavily upon the ability of our management team to devise and implement a strategy which enables us to remain competitive and cope with the current environment for home oxygen products. We pride ourselves on a history of introducing innovative products and we believe that we must continue to innovate and expand our product offerings in order to remain competitive. We are much smaller than some of our key competitors and we are unable to offer some of the prospects for advancement available at large, diversified companies. Most of our personnel are based in the Los Angeles metropolitan area which has a high cost of living.

In light of these factors, we believe that, in order to attract, motivate and retain qualified individuals, we must offer (i) base salaries which are not less than the median for comparable companies, (ii) significant opportunities for annual bonuses based on individual and company performance and (iii) an equity stake in our future. We focus on executives who are interested in working for a smaller company with significant growth potential. We also believe that, as a small company with extensive personal interaction among the executives, our compensation policies should foster team work and long term commitment to common goals. Therefore, our compensation policies are intended to reward long term commitment, while offering current compensation which is not materially below the levels of current compensation available for comparable positions at comparable companies.

Base Salary

Executive officer base salaries are based on job responsibilities and individual contributions, with reference to base salary levels at comparable companies. The Compensation Committee reviews the Report on Executive Compensation in the Medical Equipment and Supply Industry published by Top Five Data Services (the “Top Five Report”). The Top Five Report provides data on the executive compensation at 300 U.S. publicly traded companies in the medical equipment and supply industry. The Compensation Committee generally seeks to fix executive salaries at or near the mid-point for positions of comparable responsibility in companies of comparable size as reported in the Top Five Report. The Compensation Committee also considers information regarding competitive salaries and cost of living changes in Southern California.

In establishing base salaries for 2007, the Compensation Committee accepted the recommendation of the CEO that his salary, as well as that of the Chairman and one other Named Executive Officer, not be increased in view of the Company’s declining sales and net loss in the prior fiscal year. The Compensation Committee did approve (i) a 17% increase in the salary of our Senior Vice President for Sales and Marketing and (ii) a 5% increase in the salary of our Senior Vice President of Engineering and Product Development. These increases were implemented in connection with promotions granted to the two individuals and also reflected the heightened responsibilities imposed on each of these officers to complete the successful development and commercialization of innovative new products. In addition, the Compensation Committee took into account information about competitive salaries for comparable positions in Southern California.

Incentive Bonus Plan

We maintain an incentive bonus plan with fixed performance standards. The performance standards are approved annually by the Compensation Committee and are intended to reward the achievement of goals that are expected to enhance shareholder value. The performance standards are intended to combine both Company-wide objectives and individual goals, with more weight given to Company-wide objectives. Bonuses are payable yearly, based upon the extent to which the specified performance standards have been met. Achievement of 100% of the specified performance standards would entitle the Named Executive Officer to a cash bonus equal to 30% of his or her base salary. The performance standards consist of

•	Sales objective	30%

•	Pre-tax earnings objective	40%

•	Individual performance goals	30%.

The individual performance goals of the Chief Executive Officer are based upon specific targets for shareholder value, achievement of specialized sales and market goals, and product development. No incentive bonus was awarded to the Chief Executive Officer for fiscal 2007. The Senior Vice President, Engineering and Product Development received a bonus of $21,000 for achievement of individual performance goals related to design and development milestones for new products. In addition, the incentive bonus for the Senior Vice President, Sales and Marketing is calculated solely on the basis of achievement of specified, tiered sales goals. She received a bonus of $35,120 for fiscal 2007. No other Named Executive Officer received an incentive bonus in fiscal 2007.

Equity-Based Compensation

We view equity-based compensation as a mechanism for (i) aligning management interests with our shareholders, (ii) incentivizing behavior that is expected to increase shareholder value and (iii) rewarding long term commitment to the Company and its goals. We believe that all Named Executive Officers and other key employees should have a significant equity stake in the Company. Generally speaking, we do not view equity grants as a method of rewarding immediate past performance. However, the Compensation Committee will consider the Company’s recent overall performance in evaluating the extent to which equity grants should be approved. The Compensation Committee may utilize equity-based compensation to reward employees who demonstrate long term loyalty by remaining with the Company through difficult times. The Compensation Committee will also take into account the extent of a Named Executive Officer’s equity holdings in the Company, the exercise price and vesting dates of outstanding grants previously made to the Named Executive Officer and the period of time elapsed since the last equity award to the Named Executive Officer. The Compensation Committee does not utilize any fixed formula in determining the amount of equity-based compensation to award the Named Executive Officers.

Equity-based compensation is made pursuant to our 2004 Equity Incentive Plan (the “Plan”). The Plan authorizes the use of stock options, restricted stock and other equity instruments as incentive compensation for our employees. For many years, we relied primarily upon stock option grants as the equity component of our compensation programs. In more recent years, we have utilized restricted stock grants, in large part because of changes in the accounting for stock options.

All grants under the Plan must be approved by the Compensation Committee. Such approvals are obtained at meetings of the Compensation Committee. Generally speaking, such approvals are obtained at regularly scheduled meetings of the Compensation Committee, although the Compensation Committee may, on occasion, hold a special meeting to consider a proposed equity award. Equity grants are not timed to be made before the release of favorable news about the Company or after the release of unfavorable news about the Company. The exercise price for options granted under the Plan is the closing price of our stock on the American Stock Exchange on the date that the Compensation Committee meets to approve the grant, provided that, if the approval precedes an individual’s commencement of employment with the Company, then the exercise price is the closing price of our stock on the grantee’s start date. No other dates are used in determining the exercise price of stock options.

Stock options and restricted stock awards are subject to vesting requirements. Our practice has been to schedule vesting over a two to five year period, thereby incentivizing the grantees to remain with the Company. We may in the future make vesting subject to the achievement of specific milestones.

In fiscal 2007, none of our Named Executive Officers received any equity-based compensation. In deciding not to make any equity grants, the Compensation Committee took into account management’s recommendations to defer new equity grants, the Company’s operating performance and the amount of equity held by the Named Executive Officers. For example, Earl Yager, the CEO, owns shares and options aggregating approximately 2% of our fully diluted shares.

Compensation Committee Report

The Compensation Committee, comprised solely of independent directors, reviewed and discussed the above Compensation Discussion and Analysis with the Company’s management. Based on the review and discussion, the Compensation Committee recommended to the Company’s Board of Directors that the Compensation Discussion and Analysis be included in this Annual Report on Form 10-K.

Employment Agreement

Effective April 1, 1998, the Company and Thomas E. Jones entered into an employment agreement, which was amended on January 1, 2003, pursuant to which the Company employs Mr. Jones as Chairman of the Board of Directors (the “Employment Agreement”). The Employment Agreement, as amended, provides a base salary of $160,000 per year, which amount is subject to annual review by the Board of Directors. In addition, Mr. Jones is eligible to receive a bonus in an amount to be determined by the Board of Directors. Mr. Jones is entitled to participate in all stock option, severance and benefit plans adopted by the Company. The Employment Agreement does not have a specific term. The Employment Agreement may be terminated at any time by the Company, with or without cause, and may be terminated by Mr. Jones upon 90-days’ notice. If Mr. Jones resigns or is terminated for cause (as defined in the Employment Agreement), he is entitled to receive only his base salary and accrued vacation through the effective date of his resignation or termination. If Mr. Jones is terminated without cause, he is entitled to receive a severance benefit in accordance with the Company’s Severance and Change of Control Plan (the “Severance Plan”) or, if such Severance Plan is not applicable, a severance benefit equal to 200% of his salary and incentive bonus for the prior fiscal year. A description of the Severance Plan is set forth below.

Severance and Change of Control Plan

The Company has adopted a Severance and Change of Control Plan pursuant to which nine (9) of the Company’s officers have entered into Severance and Change of Control Agreements with the Company (the “Severance Agreements”). The Severance Agreements provide that the executive officer is entitled to a lump sum severance benefit equal to 200% of his aggregate compensation for the prior calendar year (the amounts vary for other officers) if the officer is terminated without cause (as defined in the Severance Agreements) and not offered a comparable position within 60 days or if the executive suffers a change in duties, in either case, within 24 months of a Change of Control or Ownership Change of the Company (as defined in the Severance Agreements). If any payment due a named executive officer pursuant to the Severance Agreements would be deemed an excess parachute payment under Section 280G of the Internal Revenue Code, then the Company may reduce such payment to the extent necessary to avoid all taxes and penalties under Section 280G. Separately, the Company provided for accelerated vesting of all outstanding options upon a Change of Control or Ownership Change of the Company.

A change in duties is defined in the Severance Agreements to include, among other things, an involuntary reduction in authority, any reduction in annual salary, a reduction of 10% or more in aggregate compensation or re-location to a site more than 50 miles from the executive’s principal place of employment.

A Change of Control or Ownership Change shall be deemed to have occurred if (i) as a result of a tender offer or sale of stock any person acquires 20% or more of the Company’s Common Stock, (ii) the Company merges into another corporation or, as a result of a merger, shareholders of the Company own less than 70% of the voting stock of the surviving entity, (iii) more than one third (1/3) of the Company’s directors are replaced during any 12-month period by directors who were not endorsed by a majority of the Board, (iv) the Company is dissolved or sells substantially all of its assets, or (v) any other event occurs which the Board of Directors deems to constitute an Ownership Change.

Compliance with Internal Revenue Code Section 162(m)

Section 162(m) of the Internal Revenue Code disallows a tax deduction to publicly held companies for compensation paid to certain of their executive officers, to the extent that compensation, whether payable in cash or stock, exceeds $1 million per covered officer in any fiscal year. The limitation applies only to compensation that is not considered to be performance-based. Non-performance-based compensation paid to the Company’s executive officers for the 2005 fiscal year did not exceed the $1 million limit per officer, there was no non-performance-based compensation paid to the Company’s executive officers for the 2006 fiscal year, and the Committee does not anticipate that any non-performance-based compensation payable in cash to the executive officers for the 2007 fiscal year will exceed that limit. Accordingly, the Committee has decided not to take any action at this time to limit or restructure the elements of cash compensation payable to the Company’s executive officers but will reconsider this decision should the individual cash compensation of any executive officer ever approach the $1 million level. The Company’s Stock Option Plan has been structured so that any compensation deemed paid by the Company in connection with the exercise of option grants made under that plan with an exercise price equal to the fair market value of the option shares on the grant date will qualify as performance-based compensation that will not be subject to the $1 million limitation on deductibility.

Item 12. Security Ownership of Certain Beneficial Owners and Management.

Item 14. Principal Accountant Fees and Services.

Accountant Fees and Services

During the fiscal years ended March 31, 2007 and 2006, KPMG LLP and Rose, Snyder & Jacobs provided various audit, audit-related and non-audit services to us as follows:


	Rose, Snyder and Jacobs				KPMG
Fee Category	Fiscal 2007 fees		Fiscal 2006 fees		Fiscal 2007 fees		Fiscal 2006 fees

Audit Fees ⁽¹⁾	$	14,400		-0-	$	166,100	$	154,000
Audit Related Fees ⁽²⁾		-0-		-0-		-0-		-0-
Tax Fees ⁽³⁾		-0-		-0-	$	26,905	$	21,500

Total Feels	$	14,400		-0-	$	193,005	$	175,500


(1)		Aggregate fees billed for professional services rendered for the audit of our 2007 and 2006 fiscal year annual financial statements and review of financial statements included in our quarterly reports on Form 10-Q or services that are normally provided in connection with statutory and regulatory filings or engagements for the 2007 and 2006 fiscal years.

(2)		Aggregate fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements which are not reported under “Audit Fees” above.

(3)		Aggregate fees billed for tax compliance and tax planning.

Our Audit Committee has considered whether provision of the above services other than audit services is compatible with maintaining the independent accountant’s independence and has determined that such services have not adversely affected Rose, Snyder, and Jacobs’ or KPMG LLP’s independence.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Accountants

The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by the independent accountants. These services may include audit services, audit-related services, tax services, and other services. Pre-approval is generally provided for up to one (1) year, and any pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. The independent accountants and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent accountants in accordance with this pre-approval and the fees for the services performed to date. The Audit Committee may also pre-approve particular services on a case-by-case basis.

Since the May 6, 2003, effective date of the Securities and Exchange Commission rules stating that an auditor is not independent of an audit client if the services it provides to the client are not appropriately approved, each new engagement of KPMG LLP was approved in advance by the Audit Committee, and none of those engagements made use of the de minimus exception to pre-approval contained in the SEC’s rules.

Audit Committee Report

The following is the report of the Audit Committee of the Board of Directors of the Company. The information contained in this report shall not be deemed to be “soliciting material” or to be “filed” with the Securities and Exchange Commission, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that the Company specifically incorporates it by reference in such filing.

On behalf of the Board of Directors, the Audit Committee monitors the Company’s financial reporting processes and internal controls, as well as the Company’s relationship with its independent accountants and the performance of such accountants. All of the members of the Audit Committee are independent directors, and the Chairman of the Audit Committee has been determined to have the expertise to serve as chairman by the Corporate Governance Committee. The Board of Directors has adopted a charter for the Audit Committee, which can be accessed under the Investor Relations section on CHAD’s website.

Management has the primary responsibility for preparation of the Company’s financial reports, the Company’s financial reporting systems, and its internal controls. The Audit Committee is not intended to supersede in any respect management’s responsibilities in this regard. Management has represented to the Audit Committee that the Company’s financial statements were prepared in accordance with generally accepted accounting principles, and the Audit Committee has reviewed and discussed such financial statements with management and with the Company’s independent accountants. The Audit Committee has also discussed with the independent accountants their evaluation of the Company’s financial reporting systems and internal controls, their plan of audit for fiscal 2007, the application of new accounting principles to the Company’s financial statements, and other matters required to be communicated to the Committee by the independent accountants pursuant to standards established by the American Institute of Certified Public Accountants. The Audit Committee has received from the independent accountants a letter addressing matters which might bear on the independence of the accountants as required by Independence Standards Board Standard No. 1. The Audit Committee has discussed independence issues with the accountants and has reviewed their fees and scope of services rendered to the Company. The Audit Committee has discussed the performance of the independent accountants with the Company’s management.

In reliance on the foregoing, the Audit Committee has recommended to the Board of Directors the inclusion of the audited financial statements in the Company’s Annual Report on Form 10-K for the year ended March 31, 2007.

Submitted by the Audit Committee of the Board of Directors,
