Item 1. Business

The Merger Agreement

On February 11, 2019, the Company, Edwards Lifesciences Holding, Inc., a Delaware corporation and a wholly-owned subsidiary of Edwards Lifesciences Corporation ("Edwards" or the "Acquiror") and Crown Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of the Acquiror ("Merger Sub"), entered into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which, subject to the satisfaction or waiver of the conditions set forth therein, Merger Sub will merge with and into the Company (the "Merger"), with the Company continuing as the surviving company and a wholly-owned subsidiary of the Acquiror. The Board of Directors of the Company has unanimously approved the Merger Agreement, the Merger, and the other transactions contemplated thereby.

On the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the "Effective Time") and as a result of the Merger, each share of Company common stock issued and outstanding immediately prior to the Effective Time (other than shares of Company common stock owned by the Company as treasury stock or owned directly by the Acquiror or any of its subsidiaries (including Merger Sub) or shares of Company common stock the holders of which have properly perfected their appraisal rights under Delaware law) will be converted into the right to receive $2.45 per share in cash (the "Merger Consideration") without interest or dividends thereon.

The Merger Agreement also provides that, as a condition to the Acquiror's obligation to effect the Merger, each holder of Company Series A Convertible Preferred Stock and Series A Exchangeable Preferred Stock outstanding, immediately prior to the Effective Time, shall consent to the conversion of such stock into Company common stock. Subject to such conversion, at the Effective Time, the holders of such preferred stock will be entitled to receive the Merger Consideration as holders of the Company's common stock.

- 4 -

The parties' obligations to consummate the Merger, which is expected to close during the second quarter of 2019, are subject to stockholder approval and certain additional customary closing conditions, including, among other things, (i) the accuracy of the other party's representations and warranties contained in the Merger Agreement (subject to certain materiality or material adverse effect qualifiers, as described in the Merger Agreement) and the other party's compliance with its covenants and agreements contained in the Merger Agreement in all material respects; (ii) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the receipt of other required antitrust approvals; and (iii) no law having been enacted after the date of the Merger Agreement that prohibits the Merger and no order having been issued after the date of the Merger Agreement preventing the consummation of the Merger. The obligations of the Acquiror and Merger Sub to consummate the Merger are further subject to the following conditions: (i) no pending proceeding brought by a governmental entity in a U.S. federal district court seeking to restrain, prohibit, challenge, or otherwise materially limit the parties' or their subsidiaries' ability to consummate the Merger or the other transactions contemplated by the Merger Agreement; and (ii) the absence of any effect, change, development, event, circumstance, occurrence, condition, fact, or state of facts that has had or would reasonably be expected to have a "company material adverse effect" (as defined in the Merger Agreement) with respect to the Company and its subsidiaries, taken as a whole. The closing of the Merger is not subject to a financing condition.

The Merger Agreement contains certain termination rights for the Company and the Acquiror, including the right of the Company to terminate the Merger Agreement to accept a "company superior proposal" (as defined the Merger Agreement) after complying with certain requirements. In addition, either party may terminate the Merger Agreement if the Merger is not consummated on or before November 8, 2019. The Merger Agreement further provides that the Company may be required to pay the Acquiror a termination fee of $3.5 million under certain specified circumstances, including if the Acquiror terminates the Merger Agreement due to a change in the recommendation by the Company's Board of Directors for the Merger or due to the Company's material breach of its non-solicitation obligations set forth in the Merger Agreement. The Merger Agreement also provides that in case it is terminated by either the Acquiror or the Company following a failure to obtain the required vote of the Company's stockholders to adopt the Merger Agreement, the Company shall reimburse the Acquiror up to $1.0 million of certain of its transaction expenses, which payment, if any, will reduce on a dollar-for-dollar basis any termination fee otherwise owed to the Acquiror.

The foregoing description of the Merger Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, which is attached as Exhibit 2.1 to the Company's Current Report on Form 8-K filed with the SEC on February 12, 2019. Additional information about the Merger and the Merger Agreement is set forth in the Company's definitive proxy statement filed with the SEC on March 13, 2019.

Our Business

We are a medical technology company that develops, manufactures, and markets non-invasive cerebral and tissue oximeters used in patient monitoring that are consistent with our Vision:

"That no patient is harmed by undetected tissue hypoxia."

Our principal products are the FORE-SIGHT® and FORE-SIGHT ELITE® brand tissue oximeters and sensors. With a simple non-invasive adhesive sensor applied to the skin, these products alert clinicians to the oxygenation levels of a patient's brain or other body tissue under the sensor during medical procedures to avoid harm caused by insufficient oxygen, otherwise known as hypoxia. The FORE-SIGHT product line represented nearly all of our 2018 sales from continuing operations. We also sell a small volume of service repairs for legacy products.

We believe our FORE-SIGHT tissue oximetry products are best-in-class and place CASMED in a unique position both to gain accounts from competitors and expand the clinical application for monitoring tissue oxygenation. Standard non-invasive parameters, such as pulse oximetry and blood pressure, provide only surrogate markers of tissue oxygen delivery. The indirect or systemic nature of these parameters forces clinicians to infer the adequacy of oxygenation in vital organs, including the brain, during medical procedures. However, data convincingly show that clinician inferences of cerebral oxygenation during medical procedures often do not correlate with actual tissue oxygenation levels. Therefore, potentially dangerously low levels of cerebral oxygenation often go unrecognized, correlating to high levels of patient harm. However, direct monitoring of cerebral and tissue oxygenation with FORE-SIGHT oximeters provides a unique and powerful tool that empowers clinicians to recognize and treat potentially dangerous tissue hypoxia to avoid adverse clinical outcomes.

- 5 -

We believe the FORE-SIGHT tissue oximeter provides clinicians the most accurate and reliable readings and is well-positioned to compete in an expanding market.

Our products are typically sold to hospitals. Clinician users include anesthesiologists, perfusionists, and surgeons in an operating room, and intensivists and nurses in intensive care units.

Strategy Execution

CASMED has completed significant product line divestitures in recent years and has successfully executed its multi-year strategic goal of solely focusing on the market opportunity for FORE-SIGHT oximetry. With the divestiture of its last two non-FORE-SIGHT legacy product lines completed in 2017, the Company's transformation from a low-margin, commodity, capital medical equipment business into a high-growth, high-margin business is complete, with disposable sensor sales representing 88% of 2018 sales from continuing operations.

Our 2018 achievements include the following:

·	Worldwide FORE-SIGHT sales rebounded in 2018, increasing 18% over 2017.

·	Worldwide sensor revenue growth accelerated to greater than 20% in the third and fourth quarters, with full-year growth of 18%.

·	We shipped a net of 363 FORE-SIGHT ELITE monitors worldwide in 2018, including 203 net monitors in the U.S., raising the U.S. adjusted installed base to 1,458 FORE-SIGHT ELITE monitors, an increase of 17% over the adjusted installed base at December 31, 2017.

·	The five-year FORE-SIGHT sales compound average growth rate was 19% at the end of 2018 for overall sales and 20% for U.S. sales.

·	We completed a multi-year effort to redesign our FORE-SIGHT ELITE disposable sensors for manufactur-ability, realizing substantial cost reductions beginning in the second quarter of 2018.

·	We received FDA 510(k) clearance for our FORE-SIGHT OEM Oximetry Module. The OEM module permits the use of FORE-SIGHT oximetry without a standalone FORE-SIGHT monitor. The design allows tissue oximetry values to be displayed on a third-party monitor with minimal user-interface modifications.

Description of Products and Services

The Company reports two categories of sales within one reportable business unit:

·	Tissue Oximetry Monitoring – includes sales of the Company's FORE-SIGHT tissue oximeter monitors, sensors, and accessories.

·	Service and Other – includes sales of service parts and repairs and other miscellaneous sales.

Tissue Oximetry Monitoring

CASMED's FORE-SIGHT tissue oximeter technology provides clinicians with a simple, non-invasive, quantitative measurement of oxygenation of cerebral tissue typically during surgery or critical care situations. The percentage saturation of cerebral hemoglobin with oxygen is obtained by placing a sensor on the skin on both the right and the left side of the patient's forehead. The FORE-SIGHT ELITE sensors emit five different wavelengths of infrared light that harmlessly penetrate into the cerebral tissue and are partially reflected back to photo-detectors in the same sensor. An exclusive algorithm then determines the percentage of hemoglobin that is saturated with oxygen in the blood of the brain tissue underlying each sensor. Through these proprietary and patented processes, FORE-SIGHT provides clinicians with an accurate, absolute numerical measure of tissue oxygenation.

In addition to cerebral monitoring, FORE-SIGHT can also be used to monitor the oxygenation of other tissues such as muscle tissues of adults and the abdominal tissues in newborns even weighing less than four kilograms.

- 6 -

By non-invasively and continuously measuring absolute cerebral and tissue oxygen levels, our FORE-SIGHT tissue oximeter enables clinicians to identify and quickly react to dangerously low brain oxygen levels and empowers them to provide better care.

We believe that FORE-SIGHT incorporates a combination of features that permit obtained oxygenation values to be more accurate and, therefore, more actionable by clinicians in critical care environments. Special design features include the following:

·	CASMED's FORE-SIGHT ELITE sensors emit five wavelengths of light, permitting an increased level of signal acquisition, thus providing sufficient data to solve for other optical variables in the tissue sample, such as melanin in the skin, which would otherwise confound a tissue oximetry reading.

·	CASMED's FORE-SIGHT sensors for adults are designed with a preferred geometry, maximizing the distance between the light source and the farthest photo-detector, thereby providing a light pathway that penetrates deeper into the tissue, giving a greater tissue sample for interrogation.

·	CASMED'S FORE-SIGHT sensors also are maximized for children and come in different configurations with each being tailored precisely to the size of the patient to maximize accuracy and ease of use, all with the preservation of skin integrity in mind.

·	CASMED's FORE-SIGHT patented and proprietary algorithm utilizes a combination of methods including a unique on-patient calibration to sort out optical signals created by non-critical background tissue that otherwise can confound measurement of oxygenated hemoglobin levels.

CASMED's FORE-SIGHT algorithms are specifically designed for different body locations given that we believe clinicians' expected levels of accuracy cannot be met with the same algorithm for such materially different physiologies as, for example, that of an adult forehead and that of a newborn's flank.

We believe our FORE-SIGHT oximeter helps clinicians solve a serious deficit in the care of many critical care patients. Unrecognized and dangerous desaturation events occur with much greater frequency than previously known and can only be properly identified with the direct measurement that tissue oximeters provide. Given this evidence, we believe our best-in-class FORE-SIGHT technology continues to gain clinical adoption in new and existing accounts and is well-positioned in the market for future growth.

During 2018, a net total of 363 monitors were shipped worldwide. As of December 31, 2018, the adjusted installed base of U.S. monitors was 1,458 monitors, up 17% from the adjusted installed base at December 31, 2017. The adjusted installed base includes only FORE-SIGHT ELITE monitors and excludes first-generation devices which are no longer in use by U.S. customers. The quantity of "net units shipped" that we report each fiscal quarter adds to this cumulative total and reflects the number of monitors shipped to customers less returns. The cumulative total reported installed base is not affected by exchanges or monitor upgrades.

The Need for Tissue Oxygenation Monitoring

Oxygen is necessary to keep cells viable. The brain has a very high metabolic rate, consuming approximately 20% of the body's oxygen at rest. The brain, of course, through cognitive function and memory, defines who we are. It is also the organ that is least resistant to oxygen deprivation. Lack of sufficient oxygenation in the brain can cause neurologic injury such as cognitive impairment, stroke, paralysis, coma, and/or hypoxic encephalopathy. These injuries can result in severe morbidity or even death. Dangerous deficits in brain hemoglobin saturation (reflecting decreased brain oxygen levels) are termed "desaturation events" because the hemoglobin of the blood is no longer sufficiently "saturated" with oxygen molecules. Desaturations can be caused by many factors. The brain responds to insufficient levels of oxygen by increasing ventilation, cardiac output, and blood pressure in order to increase oxygen delivery. It also vasodilates to increase brain blood flow. These biologic processes of optimizing oxygen delivery vs. demand can be compromised by illness, surgical intervention, trauma, and anesthesia; and neonates and children have immature auto-regulation capabilities.

- 7 -

Most conventional monitoring is ultimately employed to assure an adequate balance between oxygen supply and demand. Standard parameters, such as pulse oximetry, heart rate and blood pressure determinations, capnometry, and cardiac output assessment, each provide only indirect predictions of cerebral oxygenation. From that information, a clinician can only infer that a patient's brain inadequately oxygenated. Data from cerebral oximetry convincingly shows that the estimations clinicians make about cerebral oxygenation based solely on these indirect measures are frequently wrong and that threatening cerebral desaturation events occur without recognition. Thus, in many acute care settings, such as surgery, intensive care, and other critical care environments, patients are exposed to potentially damaging cerebral hypoxia that might be prevented if recognized.

Data in support of this clinical proposition is substantial. FORE-SIGHT and FORE-SIGHT ELITE have been well validated with FDA-compliant methods. FORE-SIGHT also has proven to have high levels of accuracy even when compared to competitive technologies. The incidence rate of cerebral desaturation events (CDE's) is very high and is prevalent in many common surgeries as indicated in the sampling of studies cited in the following table.

The harm associated with these cerebral desaturations is well documented. Low levels of cerebral oxygen saturation correlate to poorer outcomes such as: post-operative nausea; cognitive impairment including memory loss; longer lengths of stay; stroke; and even death. Yet, very simple interventions are available to clinicians to successfully reverse these low levels of oxygen. Standard interventions include eliminating mechanical blockage, increasing inspired oxygen levels, increasing blood flow or blood pressures, or transfusing units of blood.

This solid and growing body of clinical evidence substantiates the premise that measuring cerebral oximetry offers valuable insight to clinicians during the management of critical care patients which could permit them to increase safety, improve clinical outcomes, and reduce costs.

The Market for Tissue Oximetry

Cerebral desaturation events occur with much greater frequency than previously believed. The large and growing body of published literature in support of cerebral oximetry provides a solid academic and data-driven support for

- 8 -

the expanded use of the product in a variety of critical care settings including: heart surgery; lung surgery; major vascular surgery; neurosurgery; surgeries that provide a risk of large blood loss, such as orthopedic hip and spine; surgeries on elderly patients or those with compromised vascular systems or other co-morbidities; surgeries with non-supine patient positioning, such as orthopedic "beach chair" shoulder surgery and bariatric surgery; trauma care; cardiac arrest; and intensive care patient management in adult, pediatric, and neonatal wards, among others. Therefore, in the U.S. alone, cerebral monitoring could prove valuable for millions of patients each year.

While we believe the eventual addressable market for tissue oximetry exceeds $800 million, we estimate current total worldwide annual sales of tissue oximetry to be approximately $125 million. Given the broad potential applicability of this parameter and the small current rate of market penetration, we also believe that market rates of growth can accelerate, particularly as the use of oximetry moves toward becoming a standard of care.

The literature in support of tissue oximetry, in general, and FORE-SIGHT oximetry, in particular, will play an increasingly important role in the expansion of the tissue oximetry market as clinicians continue to be educated regarding the potential benefits of this parameter. Consequently, a significant part of our longer-term strategy is to continue to encourage and support research related to the need for cerebral oximetry and its efficacy in improving care. FORE-SIGHT has already been referenced in hundreds of papers, abstracts, and posters, and the literature in support of the product grows every year.

Government Regulation

Medical products of the type currently being marketed and under development by the Company are subject to regulation under the Food, Drug and Cosmetic Act (the "FD&C Act") and numerous acts and amendments such as the Quality System Regulations ("QSR").

In addition, depending upon product type, the Company must also comply with those regulations governing the Conduct of Human Investigations, Pre‑Market Notification Regulations, and other requirements, as promulgated by the FDA. The FDA is authorized to inspect a device, its labeling and advertising, and the facilities in which it is manufactured, in order to ensure that the device is not manufactured or labeled in a manner which could cause it to be in violation of the FD&C Act.

The FDA has adopted regulations which classify medical devices based upon the degree of regulation believed necessary to assure safety and efficacy. A device is classified as a Class I, II, or III device. Class I devices are subject only to general controls. Class II devices, in addition to general controls, are or will be subject to "performance standards." Most devices are also subject to the 510(k) pre‑market notification provision. In addition, some Class III devices require FDA pre‑market studies before they may be marketed commercially because their safety and effectiveness cannot be assured by the general controls and performance standards of Class I or II devices.

The Company's products are Class II devices, and most require FDA clearance under Section 510(k) of the FD&C Act.

The last factory inspection of the Company by the FDA occurred during April 2016. The inspection resulted in an FDA-483 Inspection Observation Report which listed various non-conformities. The Company provided a written response to those observations. The FDA, satisfied with the Company's response and the related actions taken, closed the inspection on June 2, 2016.

International Regulatory Compliance

CASMED maintains certification to ISO 13485:2016 by the Notified Body, BSI Inc., for its manufacturing facility. These certifications and compliance with the Medical Device Directive allow CASMED to use the "CE" mark on its products. The CE mark is required for medical devices to gain access to the European Union ("EU") common market and other non-EU markets as well. The FDA, recognizing the value of this universally-accepted quality system, has patterned its Quality System Regulations after ISO 9001 and ISO 13485. CASMED believes it maintains full compliance with ISO 13485:2016 and the EU's Medical Device Directive, as evaluated by annual assessment.

Manufacturing and Quality Assurance

The Company assembles, tests, packages, or ships its products from its facility in Branford, Connecticut. The various finished goods or components for the products, which include plastic moldings, wire, printed circuit boards, sub-assemblies, and many other parts, are obtained from outside vendors, some of which are outside of the United States. The Company has not experienced any sustained interruption in production or the supply of components and does not anticipate any difficulties in obtaining the components necessary to manufacture its products.

Quality assurance procedures are performed by the Company at its Branford, Connecticut, facility and at its suppliers' facilities to standards set forth in the FDA's "Quality System Regulations". These procedures include the initial qualification of the supplier, inspection of components, and testing of finished goods.

Customers

Our five largest customers accounted for approximately 16% and 14% of sales from continuing operations in 2018 and 2017, respectively. Each of these customers accounted for less than 10% of sales from continuing operations.

Backlog

The Company's backlog generally includes orders for products shippable on a current basis. The majority of the Company orders are shipped within several days of customer purchase order acceptance. Total backlog, therefore, is not a meaningful indicator of the Company's future sales.

Item 1A. Risk Factors

Our business faces many risks. If any of the events or circumstances described in the following risk factors actually occur, our business, financial condition, or results of operations could suffer, and the trading price of our common stock could decline. The risks described below may not be the only risks we face. Additional risks that we do not yet know of or that we currently believe are immaterial may also impair our business operations. You should consider the following risks, as well as the other information included or incorporated by reference in this Form 10-K, before deciding to invest in our common stock.

Our merger with Edwards could be delayed or fail to close, which could adversely affect our financial condition and could negatively impact our stock price.

On February 11, 2019, we entered into a Merger Agreement pursuant to which we agreed to be merged into a wholly-owned subsidiary of Edwards. We will incur significant transaction costs relating to the Merger, including legal, financial advisory, and other expenses. In general, these expenses are payable by us whether or not the Merger is completed. If the Merger is not completed under specific circumstances provided in the Merger Agreement, we may be required to pay Edwards a termination fee of $3.5 million or reimburse Edwards for certain expenses up to $1 million. The payment of such transaction costs or termination fees and expense would have an adverse effect on our financial condition, results of operations, and cash flows. In addition, we could be subject to litigation in the event the Merger is not consummated, which could subject us to significant liability for damages and result in the incurrence of substantial legal fees. The current price of our stock may reflect an assumption that the pending Merger will occur, and failure to complete the Merger could result in a decline in our stock price.

In addition, the Merger presents the following additional risks and uncertainties for the Company:

●

the occurrence of any event, change, or other circumstances that could give rise to the termination of the Merger Agreement;

●

the outcome of any legal proceeding that has been or may be instituted against CASMED and others relating to the Merger Agreement;

●

the inability to complete the Merger due to the failure to obtain stockholder approval, the failure to obtain regulatory approvals, or the failure to satisfy other conditions to consummation of the Merger;

●

the failure of the Merger to close for any other reason;

●

risks that the proposed transactions disrupt current business plans and operations and the potential difficulties in attracting and retaining senior management or employees as a result of the Merger;

●

business uncertainty and contractual restrictions during the pendency of the Merger;

●

the fact that, under the terms of the Merger Agreement, we are unable to solicit certain other acquisition proposals during the pendency of the Merger;

●

the diversion of management's attention from ongoing business concerns;

●

the effect of the announcement of the Merger on our customer and supplier relationships, operating results, and business generally; and

●

the timing of the completion of the Merger and the impact of the merger on our indebtedness, capital resources, cash requirements, profitability, management resources, and liquidity.

- 12 -

We have a recent history of net losses and are subject to risks regarding future liquidity.

We have experienced operating losses during our last ten fiscal years. The loss from continuing operations was approximately $5,961,000 for the 2018 calendar year, and the accumulated deficit was approximately $49,388,000 as of December 31, 2018. We do not anticipate a return to operating profits in the near-term, and there can be no assurance that we will be able to improve our results of operations in the near-term or at all.

As of December 31, 2018, the Company had cash-on-hand and amounts available under its Loan Agreement totaling $5,272,000. As such, our ordinary short-term capital needs are expected to be met from cash-on-hand and borrowings available from the revolving line-of-credit under our Loan Agreement, which was unused as of December 31, 2018. Management also believes its cash balances and available borrowings are sufficient to support operations through March 31, 2020. Management further believes that, given the Company's current and expected rate of cash consumption over the next 12 months together with the principal repayments required under its Loan Agreement, it should, nonetheless, if the merger transaction with Edwards is not completed, take action to improve its liquidity until such time that the Company can generate positive cash flow from operations. Management estimates it will not achieve positive cash flow until late 2020. Such actions to enhance liquidity may include seeking further changes in its debt instruments (including waivers, modifications, and/or replacement of current agreements), reducing otherwise planned expenditures and operating expenses, or raising additional funds through the issuance of equity securities.

Cash flows may be impacted by a number of factors, including changing market conditions; market acceptance of the FORE-SIGHT system; and U.S. government regulations, including the continued imposition of substantial tariffs, and other trade barriers imposed by foreign governments on our exports, and the loss of one or more key customers. There can be no assurance that we will be successful in modifying or refinancing our debt instruments or raising additional capital if the need arises. The failure to raise any necessary additional capital on acceptable terms, or at all, would have a material adverse effect on our business and results of operations.

We are a small company in a highly competitive industry.

Competition from other medical device companies, diversified healthcare companies, and research and academic institutions is intense and expected to increase. Many companies engaged in the medical device sector have substantially greater financial and other resources, as well as greater development capabilities, and substantially greater experience in testing products, obtaining regulatory approvals, and manufacturing, marketing, and distributing medical devices than we do.

Other companies may succeed in developing and commercializing products earlier than we do. In addition to competing with universities and other research institutions in the development of products, technologies, and processes, the Company may compete with other companies in acquiring rights to products or technologies from universities. Also, the medical device market is experiencing increasing customer concentration, due to the emergence of large purchasing groups and hospital systems. We cannot assure you that we will develop products that are more effective or achieve greater market acceptance than competitive products or that our competitors will not succeed in developing products and technologies that are more effective than those being developed by us or that would render our products and technologies less competitive or obsolete. Moreover, there can be no assurance that we will be able to successfully sell to large purchasing groups, which are increasingly looking to suppliers that can provide a broader range of products than we currently offer.

Our business is almost entirely dependent on our FORE-SIGHT tissue oximetry products.

Sales of our FORE-SIGHT tissue oximetry products represented nearly all of our net sales from continuing operations for both 2018 and 2017. Our business strategy in recent years has been to transform CASMED from a low-margin commodity capital medical equipment business into a high-growth, high-margin medical disposables business. A key aspect of this strategy has been to focus on the growth of our FORE-SIGHT tissue oximetry products, while exiting or de-emphasizing our other various lines of business. However, this strategy results in additional concentration risks. In the absence of significant other lines of business, we are subject to a greater degree on the success of our FORE-SIGHT tissue oximetry products. Any adverse business or other events relating to our FORE-SIGHT tissue oximetry products, including the inability to obtain sufficient levels of product from our overseas or U.S. based suppliers due to manufacturing disruptions, transportation delays, new or substantial customs or tariffs on the manufacture of foreign goods, or other risks as described elsewhere in this Item 1A, will result in a proportionately greater potential negative impact on our business and financial condition.

- 13 -

Our business is impacted by customer concentration.

The Company's five largest customers accounted for approximately 16% and 14% of sales from continuing operations in 2018 and 2017, respectively. The loss of significant customers, especially in the aggregate, could have a material adverse effect on our financial position and results of operations.

Our operations depend on a small number of key suppliers.

A significant percentage of our product components are purchased from a few suppliers located outside of the United States. Our suppliers may encounter problems during manufacturing due to a variety of reasons, including failure to follow specific protocols and procedures, failure to comply with applicable regulations, equipment malfunctions, labor shortages, or environmental factors. In addition, we purchase both raw materials used in our products and finished goods from various suppliers and may have to rely on a single-source supplier for certain components of our products where there are no alternatives available. Although we anticipate that we have adequate sources of supply and/or inventory of these components to handle our production needs for the foreseeable future, if we are unable to secure on a timely basis sufficient quantities of the products we use for manufacture or for sale, if we encounter delays or contractual or other difficulties in our relationships with these suppliers, or if we cannot find suppliers at an acceptable cost, then the manufacture or sale of our products may be disrupted, which could have a material adverse effect on our business.

We are devoting substantial resources to the development and marketing of our tissue oximetry products.

We expect to devote a significant amount of resources to continue the development and marketing of our FORE-SIGHT tissue oximetry products. We believe that substantial additional resources are required to further penetrate the markets for these products. Such investments include further research and development, involving significant expenditures for clinical studies, equipment for placements at customer sites, further expansion of our selling organization, marketing expenditures, and general working capital requirements. Due to our limited financial resources, there can be no assurance that we will be successful in these endeavors.

The sale of our products may result in significant product liability exposure.

As a manufacturer of medical equipment and products, we face product liability claims. We maintain product liability insurance in an aggregate amount of $5 million. We cannot assure you that this insurance coverage will be adequate to cover any product liability claims that occur in the future or that product liability insurance will continue to be available at reasonable prices. Any product liability judgments or settlements in excess of insurance coverage could have a material adverse effect on our business and results of operations.

Our business could be adversely affected if we cannot protect our proprietary technology or if we infringe on the proprietary technology of others.

Our proprietary technology aids our ability to compete effectively with other companies in certain markets in which we compete. Although we have been awarded or have filed applications for numerous patents, these patents may not fully protect our technology or competitive position. Further, our competitors may apply for and obtain patents that will restrict our ability to make and sell our products.

Our competitors may intentionally infringe our patents. Third-parties may also assert infringement claims against us. Litigation may be necessary to enforce patents issued to us, to protect our trade secrets or know-how, to defend ourselves against claimed infringement of the rights of others, or to determine the scope and validity of the proprietary rights of others. The defense and prosecution of patent suits are both costly and time-consuming, even if the outcome is favorable to us. Such proceedings can be extremely expensive, and their outcome very unpredictable.

An adverse outcome in the defense of a patent suit could cause us to lose proprietary rights, subject us to significant liabilities to third-parties, or require us to license rights from third-parties or to cease selling our products. Any of these events could have a material adverse effect on our business, operating results, and financial condition. We also rely on unpatented proprietary technology that others may independently develop or otherwise obtain access to.

Our inability to maintain the proprietary nature of our technologies could negatively affect our sales and earnings.

- 14 -

Cost-containment efforts of our customers, purchasing groups, third-party payors, and governmental organizations could adversely affect our sales and profitability.

Many existing and potential customers for our products within the United States have become members of group purchase organizations (GPOs) and integrated delivery networks (IDNs) in an effort to reduce costs. GPOs and IDNs negotiate pricing arrangements with healthcare product manufacturers and distributors and offer the negotiated prices to affiliated hospitals and other members. GPOs and IDNs typically award contracts on a category-by-category basis through a competitive bidding process. In addition, competitors often approach GPO's and IDN's with attractive discounts for the purchase of bundles of products offered by those competitors that may also include tissue oximetry. Bids are generally solicited from multiple manufacturers with the intention of driving down pricing. Due to the highly competitive nature of the GPO and IDN contracting processes, we may not be able to obtain or maintain contract positions with major GPOs and IDNs and we may lose customers as they enter into contracts with our competitors. Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.

The members of such groups may choose to purchase from our competitors due to the price or quality offered by such competitors, or due to additional or "bundled" products that can be offered by our competitors to these same IDN's and GPO's. Any of these actions could result in a decline in our sales and profitability.

Distributors of our products outside of the United States and hospital purchasers also negotiate terms of sale aggressively to increase their profitability. Reductions in our average selling prices or failure to negotiate arrangements having advantageous pricing and other terms of sale could adversely affect our business, results of operations, financial condition, and cash flows.

Outside of the United States, we have also experienced pricing pressure from centralized governmental healthcare authorities and increased efforts by such authorities to lower healthcare costs. We frequently are required to engage in competitive bidding for the sale of our products to governmental purchasing agents. Our failure to offer acceptable prices to these customers could adversely affect our sales and profitability in these markets.

Defects or failures associated with our products could lead to recalls or safety alerts and negative publicity.

Manufacturing flaws, component failures, design defects, off-label uses, or inadequate disclosure of product-related information could result in an unsafe condition or the injury or death of a patient. These problems could lead to a recall of, or issuance of a safety alert relating to, our products and result in significant costs and negative publicity. Due to the strong name recognition of our brands, an adverse event involving one of our products could result in reduced market acceptance and demand for all products within that brand and could harm our reputation and our ability to market our products in the future. In some circumstances, adverse events arising from or associated with the design, manufacture, or marketing of our products could result in the suspension or delay of regulatory reviews of our applications for new product approvals. We also may undertake a voluntary recall of products or temporarily shut down production lines based on performance relative to our own internal safety and quality monitoring and testing data. Any of the foregoing problems could disrupt our business and have a material effect on our business, results of operations, financial condition, and cash flows.

We depend on international distributors for a substantial portion of our sales. Failure to establish and maintain relationships with distributors could materially and adversely affect our business, financial condition, and results of operations.

We depend on international distributors for a substantial percentage of our sales. Certain of our distribution agreements may contain terms that are not favorable to us, and as our existing distribution agreements expire, we may be unable to renew with our desired distributors on favorable terms or at all. Furthermore, competition for distributors is intense. We compete for distributors internationally with other leading medical equipment and device companies that may have higher visibility, greater name recognition and financial resources, and a broader product selection than we do. Our competitors also often enter into long-term distribution agreements that effectively prevent their distributors from selling our products. At times, we may also become engaged in contract disputes or other negotiations with distributors. Consequently, establishing relationships with new distributors, maintaining relationships with existing distributors, and replacing distributors may be difficult and time-consuming. Any disruption of our distribution network, including our failure to renew distribution agreements at favorable terms or our failure to successfully negotiate contract disputes, could negatively affect our ability to effectively sell our products and could materially and adversely affect our business, financial condition, and results of operations.

- 15 -

If we are unable to effectively structure and manage our distribution network, actions taken by our distributors could harm our corporate image and cause us to fail to meet our sales goals.

We have limited ability to manage the activities of our independent international distributors. Our distributors could take one or more of the following actions, some of which we have previously experienced and any of which could have a material adverse effect on our business, prospects, and brand:

sell products that compete with products that they have contracted to sell for us;

sell our products outside of our pricing guidelines, distorting the market price of our products;

sell our products outside their designated territory or to non-authorized end-users, possibly in violation of the exclusive distribution rights of other distributors;

directly or indirectly distribute products lacking necessary certifications into markets in violation of applicable in-country laws;

fail to adequately promote our products; and/or

fail to provide proper training, repair, and service to our end-users.

Failure to adequately manage our distribution network, or non-compliance by distributors with our distribution agreements or applicable law, could harm our corporate image among end-users of our products and disrupt our sales, resulting in a failure to meet our sales goals.

Our direct sales operations are costly, and the related ongoing operational costs could have a material adverse effect on our business.

We maintain direct sales operations in the United States and rely on direct sales for nearly all of our sales from the United States. Maintaining a direct sales force is costly. In the United States, we typically provide our direct operations personnel with payroll and other benefits that we do not provide independent distributors or manufacturer representatives. Many of these benefits are fixed costs that do not depend on sales generation. Maintaining these direct operations is costly, and if we are unable to generate sales as planned, such ongoing operational costs could have a material adverse effect on our business.

We are subject to significant government regulation.

Our business is subject to varying degrees of governmental regulation in the countries in which we operate. In the United States, our products are subject to regulation as medical devices by the FDA and by other federal and state agencies. These regulations pertain to the manufacturing, labeling, development, and testing of our devices, as well as to the maintenance of required records. An FDA regulation also requires prompt reporting by all medical device manufacturers of an event or malfunction involving a medical device where the device caused or contributed to death or serious injury or is likely to do so.

Federal law provides for several routes by which the FDA reviews medical devices before the product enters the marketplace. Medical products of the type currently being marketed and under development by us are subject to regulation under the FD&C Act and numerous acts and amendments such as the Quality System Regulations which replaced the regulations formerly called Good Manufacturing Practices. In addition, depending upon product type, we must also comply with those regulations governing the Conduct of Human Investigations, Pre-Market Regulations, and other requirements, as promulgated by the FDA. The FDA is authorized to inspect a device, its labeling and advertising, and the facilities in which it is manufactured in order to ensure that the device is not manufactured or labeled in a manner which could cause it to be injurious to health.

The FDA has adopted regulations which classify medical devices based upon the degree of regulation believed necessary to assure safety and efficacy. A device is classified as a Class I, II, or III device. Class I devices are subject only to general controls. Class II devices, in addition to general controls, are or will be subject to "performance standards". Most devices are also subject to the 510(k) pre-market notification provision. In addition, some Class III devices require FDA pre-market approval before they may be marketed commercially because their safety and effectiveness cannot be assured by the general controls and performance standards of Class I or II devices. Our products are primarily Class II devices, and several of them have required FDA notification under Section 510(k) of the FD&C Act.

- 16 -

Satisfaction of clearance or approval requirements may take up to several years or more and may vary substantially based upon the type, complexity, and novelty of the product. The effect of government regulation may be to delay marketing of new products for a considerable or indefinite period of time, to impose costly procedures upon our activities, and to furnish a competitive advantage to larger companies that compete with us. We cannot assure you that FDA or other regulatory clearance or approval for any products we develop will be granted on a timely basis, if at all, or, once granted, that clearances or approvals will not be withdrawn or other regulatory action taken which might limit our ability to market our proposed products. Any delay in obtaining, failure to obtain, or revocation of these clearances or approvals would adversely affect the manufacturing and marketing of our products and the ability to generate additional product sales. The FDA also has the authority to, among other things, deny marketing approval until all regulatory protocols are deemed acceptable, halt the shipment of defective products, and seize defective products sold to customers. Adverse action or publicity from the FDA, if any, could have a negative impact upon our results from operations.

Our business is impacted by tariffs.

Effective July 2018, the U.S. government imposed additional duties of 25% on certain imports from China under Section 301 of the Trade Act of 1974. All of our FORE-SIGHT ELITE sensor products provided by our contract manufacturer and certain of our monitor product components are subject to the tariffs. While management has considered strategies to mitigate any negative financial impact if the tariffs persist, we cannot be certain that we will be successful in our efforts to reduce or eliminate any additional costs imposed by the new tariffs or whether a financial impact will be of a short-term or long-term nature. Our gross margins were negatively affected by $355,000 of tariff costs, or 1.6% of sales during 2018. Tariff costs for the fourth quarter of 2018 were $253,000, or 4.4% of sales and at current levels of sales may exceed $1.0 million for 2019 if tariffs are levied for a full year. Other non-sensor components also have or may increase as vendors of component parts pass on tariff costs to end-users.

In response to the U.S. government tariffs on imports, the government of China imposed tariffs on certain U.S. products entering China, including products shipped to our China distributor. These tariff costs may also impact exports to China of FORE-SIGHT finished goods.

Federal regulatory reforms may adversely affect our ability to successfully market our products and impact our financial condition.

Efforts to reform the U.S. healthcare industry have resulted in legislation such as the Patient Protection and Affordable Care Act ("Affordable Care Act") and other measures which will effect changes in healthcare delivery and coverage and public and private reimbursements for services performed. Federal initiatives may also affect state programs. Legislative changes may affect hospital market expenditures for medical devices, the type and volume of procedures performed, and the demand for new and innovative products. These changes could be significant and may adversely affect the demand for our products, our results of operations, cash flows, and our overall financial condition.

Outside of the U.S., healthcare delivery and reimbursement systems vary by country. Efforts to control rising healthcare costs, changes in government-sponsored programs and participation, and various other economic factors may impact our ability to successfully market our products outside of the U.S.

Our products may become rapidly obsolete.

The markets in which we compete involve rapidly developing technology. Others may develop products that might cause products being developed, distributed, or licensed by us to become obsolete, uneconomical, or result in products superior to our products.

- 17 -

Our international business is subject to currency, regulatory, and related risks.

Our international sales subject us to currency and related risks. We expect that international sales will continue to constitute a significant portion of our business. Although we sell our products in United States dollars and have only limited currency risks, an increase in the value of the United States dollar, relative to foreign currencies in our international markets, could make our products less price competitive in these markets. Our international sales accounted for 16% and 14% of our total net sales from continuing operations for the 2018 and 2017 fiscal years, respectively.

Substantial levels of products and components purchased by us are sourced from outside the U.S. Changes in importation laws, regulations, duties or taxes by the U.S. or by other countries could have a material adverse impact on the costs and/or availability of our products.

Our business practices in countries other than the United States are governed by U.S. laws, including the Foreign Corrupt Practices Act, as well as local laws and regulatory schemes. While we believe we maintain a robust compliance program requiring adherence by our employees and distribution partners to all U.S. and foreign laws and regulatory schemes, there can be no assurances that our foreign distribution partners comply; therefore, failure could cause us to suffer the loss of the ability to sell in those jurisdictions or other liability.

An acquisition of the Company may be hindered.

Subject to the limitations set forth in the Merger Agreement with Edwards, our Board of Directors is authorized to issue from time to time, without stockholder authorization, shares of preferred stock, in one or more designated series or classes. We are also subject to a Delaware statute regulating business combinations. These provisions could discourage, hinder, or preclude an unsolicited acquisition of the Company and could make it less likely that stockholders receive a premium for their shares as a result of any takeover attempt.

We have outstanding shares of preferred stock with rights and preferences superior to those of our common stock.

The issued and outstanding shares of Series A Convertible Preferred Stock and Series A Exchangeable Preferred Stock grant the holders of such preferred stock voting, accretion, dividend, and liquidation rights that are superior to those held by the holders of our common stock.

Ownership of our shares is concentrated in the hands of a few investors which could limit the ability of our other stockholders to influence the direction of the company.

As calculated by SEC rules of beneficial ownership, Thomas, McNerney & Partners and their affiliates, and Acuta Capital Partners, LLC, each beneficially owned 31.3% and 18.0%, respectively, of our common stock as of the dates of their most recent public filings with the SEC and other available data. Accordingly, although they are not affiliated with one another, they collectively may have the ability to significantly influence or determine the election of all of our directors or the outcome of most corporate actions requiring stockholder approval. They may exercise this ability in a manner that advances their best interests and not necessarily those of our other stockholders.

Sales of a substantial number of shares of our common stock in the public market, originally issued through the conversion of preferred stock, exercise of options or warrants, or additional financing transactions, could adversely affect the market price of our common stock and would have a dilutive effect upon our stockholders.

Historically, our common stock has been thinly traded. This low trading volume may have had a significant effect on the market price of our common stock, which may not be indicative of the market price in a more liquid market. As of December 31, 2018, options and warrants for the purchase of 3,711,032 shares of our common stock were outstanding, and 10,635,019 shares of common stock were issuable upon conversion of our outstanding Series A Convertible Preferred Stock and Series A Exchangeable Preferred Stock.

We depend highly on certain key management personnel.

We believe that our future success will depend to a significant extent on the efforts and abilities of our senior management, in particular, Thomas Patton, our President and Chief Executive Officer; Dr. Paul Benni, our Chief Scientific Officer; Dr. John Gamelin, our Vice President of Research and Development; and Jeffery Baird, our Chief Financial Officer. The loss of the services of these executives could have a material adverse effect on our business and results of operations.

- 18 -

We do not expect to pay cash dividends.

We have not paid cash dividends on our common stock since inception, and at this time, we do not anticipate that we will pay cash dividends on our common stock in the foreseeable future. Furthermore, we are currently precluded from issuing dividends on our common stock pursuant to the Merger Agreement with Edwards and unless we receive the consent of holders of a majority of our outstanding Series A Convertible Preferred Stock and Series A Exchangeable Preferred Stock.

Furthermore, our agreement with our secured lender prohibits the payment of cash dividends to both common and preferred stockholders. As of December 31, 2018, $10,407,061 in dividend accretion had accumulated on the Series A Convertible Preferred Stock and the Series A Exchangeable Preferred Stock.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

The Company is leasing its headquarters and manufacturing facility in Branford, Connecticut (the "Property"), which is comprised of approximately 24,000 square feet of office and manufacturing space. The lease had an initial term of ten years, expired on September 6, 2017, and contained an option for two additional five-year periods. In January 2017, the Company executed a five-year extension on the lease effective February 1, 2017, through January 31, 2022. Annual base rent was $274,000 for the first year of the lease and is subject to annual increases of 2% for the remaining term of the lease. Under the lease, the Company is responsible for the costs of utilities, insurance, taxes, and maintenance expenses. Further, the Company is required to maintain at least $600,000 in cash and cash equivalents (increasing at 3% per annum) and net current assets of not less than $3,600,000.

The Company had leased approximately 5,000 square feet of office space adjacent to its corporate facility until such lease expired on May 31, 2018. The Company consolidated its resources into one corporate facility, following completion of approximately $118,000 of needed leasehold improvements to its main facility.

The Company believes that the corporate facility meets its current and expected operating needs and is adequately insured.

Item 3. Legal Proceedings

The manufacture and sale of our products exposes us to product liability claims and product recalls, including those which may arise from misuse or malfunction of, or design flaws in, our products or use of our products with components or systems not manufactured or sold by us. Product liability claims or product recalls, regardless of their ultimate outcome, could require us to spend significant time and money in litigation or to pay significant damages. We are currently a defendant in a product liability action related to our former sleep apnea product line. We believe that our insurance is sufficient to cover any damages and costs that are likely, with respect to these matters. There can be no assurance, however, that this will be the case with respect to these matters or any future matters.

In addition, we are or may become, in the normal course of our business operations, a party to other legal proceedings in addition to those described in the paragraph above. None of these other proceedings would be expected to have a material adverse impact on our results of operations, financial condition, or cash flows.

Merger-Related Litigation

On or about March 7, 11, 14 and 21, 2019, four putative class action complaints challenging the Merger were filed in the United States District Court for the District of Delaware, captioned Adam Franchi v. CAS Medical Systems, Inc., et al., Shiva Stein v. CAS Medical Systems, Inc., et al., Thomas Torreano v. CAS Medical Systems, Inc. et al. and Joseph Rish Jr. v. CAS Medical Systems, Inc. et al., respectively, and on or about March 11, 2019 an additional putative class action complaint challenging the merger was filed in the Superior Court for the State of Connecticut, Judicial District of New Haven at New Haven, captioned Charles New v. CAS Medical Systems, Inc., et al. The complaints were filed on behalf of the public shareholders of CASMED and name as defendants CASMED and the members of its board of directors. The complaints generally allege violations of federal securities laws with respect to purported disclosure deficiencies in the preliminary proxy statement for the merger that CASMED filed with the SEC on March 1, 2019. The complaint in the Stein action also alleges that CASMED's directors agreed to sell CASMED for inadequate consideration, the complaint in the New action also alleges that CASMED's directors agreed to sell CASMED for an unfair price as a result of an unfair sale process and the complaint in Torreano also alleges that the Merger contains preclusive deal protection provisions. The Torreano complaint also alleges claims against Edwards Lifesciences Holding, Inc. Crown Merger Sub, Inc. and Edwards Lifesciences Corporation. The complaints seek a variety of relief, including an injunction preventing the consummation of the Merger, rescission of the Merger if it is consummated or rescissory damages, attorneys' fees and expenses. The defendants have not yet responded to the complaints, but believe that the claims asserted against them are without merit.

Item 4. Mine Safety Disclosures

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

The common stock of the Company trades on the Nasdaq Capital Market, under the symbol "CASM".

The following table sets forth the approximate number of beneficial owners of common stock of the Company on December 31, 2018.

Title of Class		Number of Stockholders

Year Ended December 31, 2018 Compared to Year Ended December 31, 2017

Management Summary

Our 2018 achievements include the following:

·	Worldwide FORE-SIGHT sales rebounded in 2018, increasing 18% over 2017.

·	Worldwide sensor revenue growth accelerated to greater than 20% in the third and fourth quarters, with full-year growth of 18%.

·	We shipped a net of 363 FORE-SIGHT ELITE monitors worldwide in 2018, including 203 net monitors in the U.S., raising the U.S. adjusted installed base to 1,458 FORE-SIGHT ELITE monitors, an increase of 17% over the adjusted installed base at December 31, 2017.

·	The five-year FORE-SIGHT sales compound average growth rate was 19% at the end of 2018 for overall sales and 20% for U.S. sales.

·	We completed a multi-year effort to redesign our FORE-SIGHT ELITE disposable sensors for manufactur-ability, realizing substantial cost reductions beginning in the second quarter of 2018.

·	We received FDA 510(k) clearance for our FORE-SIGHT OEM Oximetry Module. The OEM module permits the use of FORE-SIGHT oximetry without a standalone FORE-SIGHT monitor. The design allows tissue oximetry values to be displayed on a third-party monitor with minimal user-interface modifications.

Results of Operations

The Company incurred a loss from continuing operations before income taxes for 2018 of $5,961,000, which represents an improvement of $1,510,000, or 20%, from the $7,471,000 of losses from continuing operations before income taxes reported for 2017. Increased revenues, higher gross profit margins, and controlled spending accounted for the improvement in operating results. There was no income from discontinued operations for 2018 compared to $3,388,000, net of income taxes, for 2017. Income tax expense of $1,745,000 for 2017 was offset by income tax benefits recorded against continuing operations. The Company does not expect to pay income taxes for 2018, and none were paid for 2017.

The Company incurred a net loss applicable to common stockholders of $7,664,000 for 2018, or ($0.28) per basic and diluted common share, compared to a net loss applicable to common stockholders of $3,926,000, or ($0.14) per basic and diluted common share, for 2017.

Worldwide sales of oximetry monitors and accessories for 2018 increased $318,000, or 18%, to $2,045,000 from 2017 sales of $1,727,000. A total of 358 net FORE-SIGHT ELITE monitors were shipped worldwide of which 203 ELITE monitors were shipped to U.S. customers. The U.S. adjusted FORE-SIGHT ELITE installed base of 1,458 monitors as of December 31, 2018, increased 17% over December 31, 2017.

- 23 -

Gross profit as a percentage of net sales from continuing operations was 58.0% for 2018 and 54.7% for 2017. The improvement was primarily related to the production and sales of lower cost disposable sensors which were partially offset by increased U.S. tariff charges effective July 2018. The tariff costs negatively impacted our gross profit by $355,000, or 1.6% of sales, for 2018. Slightly lower average selling prices also affected our 2018 gross profit margins.

Research and development ("R&D") expenses were $3,182,000 and $3,234,000, respectively for 2018 and 2017. The decrease of $52,000, or 2%, in 2018 was due to lower R&D project expenses. R&D expenses were approximately 15% of sales from continuing operations in 2018, down from 17% in 2017.

Selling, general, and administrative ("S,G&A") expenses increased $598,000, or 4%, to $14,016,000 for 2018 from $13,418,000 for 2017. The increases in spending resulted primarily from additional investments in our international sales effort and from certain G&A expenses including legal, consulting, and incentives.

Interest expense for 2018 was $1,470,000, an increase of $393,000 over 2017, reflecting increased debt levels, higher interest rates, and amortization of deferred finance charges.

There was no income tax benefit in the aggregate recorded for either 2018 or 2017. The Company does not expect to record taxable income during its 2018 fiscal year. Income tax benefits that have been recorded during 2018 have been offset by a deferred income tax asset valuation allowance.

Management established the valuation allowance as of December 31, 2009, as a result of then recent cumulative pre-tax losses and its estimates of future taxable income. Management has continued to perform the required analysis regarding the realization of our deferred income tax assets, concluding that a full valuation allowance is warranted. As of December 31, 2018, the deferred income tax asset valuation allowance balance was $13,016,000.

Financial Condition, Liquidity, and Capital Resources

The Company's continuing operations used $2,598,000 of cash for 2018, compared to $4,675,000 used in continuing operations during 2017, largely due to favorable changes in working capital items, such as accounts payable and accrued expense.

Net cash used in investing activities of continuing operations was $863,000 for 2018, compared to net cash provided of $3,863,000 for 2017. Cash provided by investing activities for 2017 included $4,527,000 pertaining to the sale of the Company's non-invasive blood pressure product line. The Company incurred $783,000 of capital expenditures during 2018, compared to $596,000 for 2017. For both periods, the expenditures were primarily related to placements of FORE-SIGHT oximeter monitors at customer locations. The 2018 expenditures included approximately $118,000 of leasehold improvements incurred to provide additional office space. The Company also expended $80,000 and $67,000 during 2018 and 2017, respectively, primarily related to patent registrations.

Net cash provided by financing activities of continuing operations was $1,115,000 for 2018, compared to cash used of $215,000 for 2017. During 2018, the Company entered into a bank agreement with a new lender, as described below, and repaid the outstanding balance under its previous loans together with associated payoff fees.

On May 8, 2018, the Company consummated a Loan and Security Agreement (the "Loan Agreement") with East West Bank (the "Bank"). Pursuant to the Loan Agreement, the Bank has provided a 48-month term loan (the "Term Loan") in the amount of $10,000,000 and a revolving loan (the "Revolver") in the maximum of $2,000,000, each of which expires May 8, 2022. The obligations under the Loan Agreement are secured by a lien on substantially all of the non-intellectual property assets of the Company. As of December 31, 2018, there was no outstanding balance under the Revolver. Available borrowings under the Revolver were $2,000,000 as of that date.

The Term Loan bears interest at a floating rate equal to the Bank's prime rate (not less than 4.75%) plus 3.65% (9.15% as of December 31, 2018). Under the Term Loan, 30 equal payments of $333,333 are scheduled to commence on December 1, 2019, following an 18-month period during which the Company shall make interest-only payments. The interest-only period may be extended to 21 months or 24 months under certain circumstances.

- 24 -

Revolver advances will bear interest at a floating rate equal to the Bank's prime rate (not less than 4.75%) plus 2.40% (7.90% as of December 31, 2018). Maximum borrowings under the Revolver are based upon the Company's eligible accounts receivable, as defined in the Loan Agreement, and subject to other terms and conditions.

The Company has the right to prepay the loan under the Loan Agreement in full at any time; however, if the Term Loan is prepaid prior to the first or second anniversaries of the Loan Agreement or prior to maturity, a fee of 3%, 2%, or 1%, respectively, of the Term Loan amount is due. Amounts prepaid under the Term Loan may not be re-borrowed. Upon repayment of the Term Loan at any time, the Bank is entitled to an additional fee equal to 4% of the Term Loan amount.

The Loan Agreement contains customary affirmative covenants, including covenants regarding the payment of taxes and other obligations, maintenance of insurance, reporting requirements, and compliance with applicable laws and regulations. Further, the Loan Agreement contains customary negative covenants limiting the ability of the Company and its subsidiaries, among other things, to grant liens on the pledged collateral or the Company's intellectual property, incur additional indebtedness, make certain investments and acquisitions, and dispose of assets outside the ordinary course of business. The Loan Agreement also contains financial covenants requiring the Company to achieve certain sales results and to maintain a continuing level of cash plus available borrowing capacity based on a formula. Management believes the Company was in compliance with all covenants under the Loan Agreement as of December 31, 2018.

Upon an event of default, the Bank may declare all outstanding principal and accrued but unpaid interest under the Loan Agreement immediately due and payable and may exercise the other rights and remedies provided under the Loan Agreement. The events of default under the Loan Agreement include payment defaults, breaches of covenants or representations and warranties, a material adverse change, certain adverse regulatory events, specified change of control events, and bankruptcy events.

In connection with the Loan Agreement, on May 8, 2018, the Company issued a warrant (the "Warrant") to the Bank, which provides for the right to purchase an aggregate of 218,914 shares of the Company's common stock for a five-year period, expiring on May 8, 2023, at an exercise price of $1.142 per share.

The number of shares issuable pursuant to the Warrant and the exercise price thereof are subject to adjustment only in the event of stock splits, subdivisions, reclassifications, exchanges, combinations, and similar transactions. The Warrant also contains a cashless exercise provision.

The shares associated with the Warrant were fully vested at the time of issuance. The value of the Warrant was estimated on the date of grant to be $0.57 per share using the Black-Scholes option pricing model, assuming a weighted-average expected stock price volatility of 54.8%, an expected warrant life of five years, an average risk-free interest rate of 2.76%, and a 0.0% average dividend yield. The value of the Warrant of $124,248, as calculated above, has been recorded as a debt discount and is being recognized as interest expense over the 48-month term of the Loan Agreement.

The Company incurred debt issuance costs and discounts of $895,000 associated with the Loan Agreement, including $120,000 of commitment fees together with legal and brokerage costs paid at the closing, $400,000 of final payment fees to be accrued, and $124,248 of non-cash expenses pertaining to the Warrant. The debt issuance costs and discounts will be amortized through May 8, 2022, the maturity date of the Loan Agreement. As a result of the debt issuance costs, the effective rate of the Term Loan was 11.23% at May 8, 2018 (11.96% at December 31, 2018). In addition, unamortized debt issuance costs of $264,539 together with a prepayment fee of $69,333, each pertaining to the Company's prior loan agreement, were recorded as interest expense during the second quarter of 2018 corresponding with the termination of that agreement. Finally, the accrued final payment fee of $320,000 owed to the former lenders, was repaid concurrently with the execution of the new Agreement.

The Company financed its directors' and officers' insurance premiums during 2018 under a note payable in the amount of $100,841. The note payable requires ten payments of $10,335, including interest, and is scheduled to be repaid in full by September 2019.

- 25 -

As of December 31, 2018, the Company had cash-on-hand and amounts available under its Loan Agreement totaling $5,272,000. As such, our ordinary short-term capital needs are expected to be met from cash-on-hand and borrowings available from the revolving line-of-credit under our Loan Agreement which was unused as of December 31, 2018. In addition, the Company is anticipating an earn-out payment from the sale of its non-invasive blood pressure technology in July 2017. In accordance with that agreement, the Company is entitled to a payment in August 2019 not to exceed $2,000,000, following a 24-month period ending June 30, 2019. The Company has not recorded any amounts potentially due from the earn-out payment but believes that the Company will earn all, or nearly all, of the entire amount. Management believes its cash balances and available borrowings are sufficient to support operations through March 31, 2020. Management further believes that given the Company's current and expected rate of cash consumption over the next 12 months, together with the principal repayments required under its Loan Agreement, it should, nonetheless, if the merger transaction with Edwards is not completed, take action to improve its liquidity until such time that the Company can generate positive cash flow from operations. Management estimates it can achieve positive cash flow in late 2020. Such actions to enhance liquidity may include seeking further changes in its debt instruments (including waivers, modifications, and/or replacement of current agreements), reducing otherwise planned expenditures and operating expenses, or raising additional funds through the issuance of equity securities.

Cash flows may be impacted by a number of factors, including changing market conditions, market acceptance of the FORE-SIGHT system, the loss of one or more key customers, and other factors, including those detailed in Item 1A of this report, entitled Risk Factors. There can be no assurance that the Company will be successful in modifying or refinancing our debt instruments or raising additional capital if the need arises. The failure to raise any necessary additional capital on acceptable terms, or at all, could have a material adverse effect on the Company's business and results of operations.

The Company's 2019 business plans call for operating expenditures to be slightly above 2018 levels. Capital expenditures for 2019 are expected to approximate 2018 levels. Capital expenditures include the Company's placement of FORE-SIGHT monitors in customer accounts, whereby the Company retains title to the monitor in exchange for customer purchases of disposable sensors.

The Company's results of operations were not significantly affected by inflation during 2018.

Off-Balance Sheet Arrangements

The Company has no off-balance sheet arrangements other than operating leases for office and warehouse space.

Critical Accounting Policies

The Company's financial statements have been prepared in accordance with generally accepted accounting principles in the United States. In preparing the financial statements, the Company is required to make estimated judgments. Such judgments are based upon historical experience and certain assumptions that are believed to be reasonable in the particular circumstances. Those judgments affect both balance sheet and income statement accounts and disclosures. The Company evaluates its assumptions on an ongoing basis by comparing actual results with its estimates. Actual results may differ from the original estimates. The following accounting policies are those that the Company believes to be most critical to the preparation of its financial statements.

Inventory Valuation – The Company's inventories are stated at the lower of cost or market. The Company provides allowances on inventories for any material that has become obsolete or may become unsalable based on estimates of future demand and the sale price in the market. Judgments with respect to salability and usage of inventories, estimated market value, and recoverability upon sale are complex and subjective. Such assumptions are reviewed periodically, and adjustments are made, as necessary, to reflect changed conditions. There were no significant inventory write-offs for any period presented.

Deferred Income Tax Assets – The Company has recorded deferred income tax assets for the estimated benefit of future tax deductions on inventories, property and equipment, and other accruals, as well as net operating loss carryforwards and tax credits. Based on recent cumulative pre-tax losses and the Company's estimates of future taxable income, management has established a deferred tax asset valuation allowance.

Stock-based Compensation – The Company records the fair value of stock-based compensation awards as expenses in its consolidated statements of operations. In order to determine the fair value of stock options on the date of grant, we apply the Black-Scholes option-pricing model. Inherent in this model are assumptions related to expected dividend yield, risk-free interest rate, expected stock-price volatility, expected term, and forfeiture rate. Restricted stock awards are generally based upon the closing price of the common stock on the date of the grant. Amortization of stock-based awards takes place over the vesting period associated with the award.

- 26 -

Sales and Accounts Receivable Recognition – Effective January 1, 2018, the Company adopted Accounting Standards Update ("ASU") 2016-10, Topic 606, Revenue from Contracts with Customers. The Company used the Modified Retrospective method, under which prior-year results are not restated. The standard, including the cumulative effect of its adoption, did not have a material impact on the Company's financial statements.

The core principle of the guidance in Topic 606 is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which an entity is expected to be entitled in exchange for those goods and services. The amendments in ASU 2016-10 clarify the identification of performance obligations and the licensing implementation guidance. In adopting ASU 2016-10, the Company reviewed the five steps considered fundamental to determining when to recognize revenue. Those five steps are as follows: (1) Identify the contract(s) with a customer; (2) Identify the performance obligations in the contract; (3) Determine the transaction price; (4) Allocate the transaction price to the performance obligations in the contract; and (5) Recognize revenue when (or as) the entity satisfied a performance obligation.

Terms of sale for most domestic sales are FOB origin and for most international sales are EX-Works, reflecting that ownership and risk-of-loss are assumed by the buyer at the shipping point. In addition, the Company has certain agreements with its customers to ship FOB destination, reflecting that ownership and risk-of-loss are assumed by the buyer upon receipt. While the Company accepts returns of products from its customers from time to time for various reasons, including defective goods, order entry, shipping or other errors, the Company's business practices do not include providing a right-of-return at the time of sale. Historically, such returns have not been significant. Payment terms range from prepayment to net 90 days, depending upon certain factors, including customer credit worthiness, geographic location and customer type (i.e., end-user, distributor, government, or private entity) and also includes irrevocable letters of credit for certain international shipments. Price discounts that may be taken by customers under contractual arrangements for payment of invoices within specified periods are recorded as reductions to net sales. Further, the Company accrues expected payment discounts based upon specific customer accounts receivable balances. The Company does not incur post-shipment obligations with the exception of product warranties which are generally fulfilled from the Company's corporate facilities and which costs are not material relative to the sale of the product. Accounts receivable are charged to the allowance for doubtful accounts when deemed uncollectible.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

The Company holds no derivative securities for trading purposes and is not subject in any material respect to currency or other commodity risk.

Report of Independent Registered Public Accounting Firm

The Stockholders and Board of Directors

CAS Medical Systems, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of CAS Medical Systems, Inc. and Subsidiary (the "Company") as of December 31, 2018 and 2017, and the related consolidated statements of operations, changes in stockholders' equity (deficiency), and cash flows for the years then ended, and the related notes (collectively referred to as the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. Federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

CAS Medical Systems, Inc.

Notes to Consolidated Financial Statements

(1)	THE COMPANY

CAS Medical Systems, Inc. ("CASMED" or the "Company") is a medical technology company that develops, manufactures, and distributes non-invasive patient monitoring products that are vital to patient care and are consistent with our vision that no patient is harmed by undetected tissue hypoxia. The Company's products include the FORE-SIGHT® series of absolute tissue oximeters and sensors, including the FORE-SIGHT ELITE® oximeter. We also perform service repairs that are separately reported as Service/Other. CASMED markets its products worldwide through its sales force, distributors, and manufacturers' representatives. The Company's main facility and manufacturing operations are located in the United States.

(2)	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of estimates

The preparation of financial statements, in conformity with accounting principles generally accepted in the United States of America, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and expenses during the reporting period. Estimates that are particularly sensitive to change in the near-term are inventory valuation allowances, deferred income tax asset valuation allowances, allowance for doubtful accounts, and warranty accrual. Actual results could differ from those estimates.

Principles of consolidation

The consolidated financial statements include the accounts of CASMED and one inactive subsidiary.

Cash and cash equivalents

The Company considers all highly-liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Inventories

Inventories are stated at the lower of cost, determined by the first-in-first-out method, or market.

Property and equipment

Property and equipment, including leasehold improvements, are stated at cost. Depreciation is computed using the straight-line method based on the estimated useful lives of the assets, which range from two to five years for machinery and equipment. Leasehold improvements are amortized over the life of the improvement or the lease term, whichever is shorter. Maintenance and repairs are charged to expense when incurred.

The Company owns certain FORE-SIGHT tissue oximetry monitors primarily located at customer sites within the United States. Such equipment is typically held under a no-cost program whereby customers purchase disposable sensors for use with the Company's equipment. The Company retains title to the monitors shipped to its customers under this program. The monitors are depreciated to cost-of-sales on a straight-line basis over five years.

Depreciation expense on property and equipment was $1,013,000 in 2018 and $987,000 in 2017.

F-7

Intangible and other assets

The Company reviews its intangible and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. During 2018 and 2017, the Company charged-off $21,340 and $17,276, respectively, of capitalized costs related to certain abandoned patents and trademarks. The Company believes that the carrying amounts of its long-lived assets are fully recoverable.

Intangible and other assets at December 31, 2018 and 2017 consist of:

	2018			2017

Patents and other assets	$	782,566		$	738,805
Patents pending		301,564			297,746
		1,084,130			1,036,551
Accumulated amortization		(262,589	)		(234,160	)
Total	$	821,541		$	802,391

Intangible and other assets are stated at cost. Patents are amortized on a straight-line basis over 20 years.

Expected amortization expense of intangible assets as of December 31, 2018, over the next five calendar years follows:

2019	$	38,000
2020	$	38,000
2021	$	37,000
2022	$	37,000
2023	$	36,000

Sales and accounts receivable recognition

Terms of sale for most domestic sales are FOB origin and for most international sales are EX-Works, reflecting that ownership and risk-of-loss are assumed by the buyer at the shipping point. In addition, the Company has certain agreements with its customers to ship FOB destination, reflecting that ownership and risk-of-loss are assumed by the buyer upon receipt. While the Company accepts returns of products from its customers from time to time for various reasons, including defective goods, order entry, shipping, or other errors, the Company's business practices do not include providing a right-of-return at the time of sale. Historically, such returns have not been significant. Payment terms range from prepayment to net 90 days, depending upon certain factors, including customer credit worthiness, geographic location, and customer type (i.e., end-user, distributor, government, or private entity) and also includes irrevocable letters of credit for certain international shipments. Price discounts that may be taken by customers under contractual arrangements for payment of invoices within specified periods are recorded as reductions to net sales. Further, the Company accrues expected payment discounts based upon specific customer accounts receivable balances. The Company does not incur post-shipment obligations with the exception of product warranties, which are generally fulfilled from the Company's corporate facility and which costs are not material, relative to the sale of the product. Accounts receivable are charged to the allowance for doubtful accounts when deemed uncollectible.

In the normal course of business, the Company grants credit to its customers and does not require collateral. Credit losses are provided for in the period the related sales are recognized, based upon experience and an evaluation of the likelihood of collection. Credit losses have been within management's expectations.

The Company's five largest customers accounted for approximately 16% and 14% of sales from continuing operations in 2018 and 2017, respectively. Sales to each of these customers accounted for less than 10% of sales from continuing operations.

F-8

Income taxes

On December 22, 2017, the U.S. government enacted comprehensive tax reform legislation in the form of the Tax Cuts and Jobs Act of 2017 (the "Tax Act"). The Tax Act established new tax laws that affected 2017 and beyond. One of the principal new tax laws effective January 1, 2018, was the reduction on the U.S. Federal corporate income tax rate from 35% to 21%.

The Company recognizes deferred income tax assets and liabilities for future tax consequences resulting from differences between the book and tax bases of existing assets and liabilities as well as for loss carryforwards. A valuation allowance is provided for that portion of deferred income tax assets which may not be realized.

The Company accrues for uncertain tax positions in accordance with accounting standards which prescribe a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.

The Company files U.S. Federal and multiple State income tax returns. The Company's U.S. Federal and State income tax returns prior to 2015 are closed for audit. There have been no interest and penalties related to uncertain tax positions for any periods reported herein.

Warranty costs

The Company generally warrants products against defects and failures for up to two years and records the estimated cost of such warranties at the time the sale is recorded. Estimated warranty costs are based upon actual past experiences of product returns and the related estimated cost of labor and material to make the necessary repairs.

A summary of the changes in the Company's warranty accrual at December 31, 2018 and 2017 follows:

	2018			2017

Beginning balance	$	65,000		$	100,000
Provision		14,752			27,616
Warranty costs incurred		(29,752	)		(62,616	)
Ending balance	$	50,000		$	65,000

Research and development costs

The Company expenses all research and development costs as incurred. Research and development ("R&D") includes, among other expenses, direct costs for salaries, employee benefits, professional services, clinical studies, materials, and facility-related expenses.

Advertising costs

Non-direct response advertising costs are expensed as incurred and include product promotion, samples, meetings and conventions, and print media. Advertising expense related to continuing operations was $710,000 and $696,000 in 2018 and 2017, respectively.

Loss per common share applicable to common stockholders

Basic loss per share is calculated by dividing net loss applicable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted loss per share reflects the potential dilution that could occur if common stock equivalents, such as unvested restricted common shares, outstanding warrants and options, or convertible preferred stock were exercised or converted into common stock. For all periods reported, the Company incurred net losses from continuing operations. Therefore, for each period reported, diluted loss per share is equal to basic loss per share because the effect of including such common stock equivalents or other securities would have been anti-dilutive.

F-9

At December 31, 2018, stock options and warrants to purchase 3,238,250 and 472,782 shares of common stock, respectively, were excluded from the diluted earnings per share calculation as they would have been anti-dilutive. On an as-converted basis, 10,635,019 shares of common stock pertaining to the private placement of 150,000 shares of Series A convertible and exchangeable preferred stock issued on June 8, 2011, were also excluded as they would have been anti-dilutive.

(3)	DISCONTINUED OPERATIONS

On July 25, 2017, the Company entered into an agreement pursuant to which it sold assets related to its NIBP technology product line in exchange for $4,500,000 in cash at closing and an additional payment for the purchase of inventory following a short transition services period, which concluded during September 2017. The final inventory purchased by the buyer was $86,000. In accordance with that agreement, the Company is also entitled to an additional payment in August 2019 not to exceed $2,000,000, following a 24-month period ending June 30, 2019.

On March 28, 2016, the Company consummated an agreement under which it sold certain assets related to its neonatal intensive care disposable product line for $3,350,000, including $3,035,000 in cash at closing after deductions of $100,000 for funds held in escrow for 12 months following the closing and $215,000 for inventory to be purchased following a transition services agreement which was effectively concluded at December 31, 2016. The inventory to be purchased from the Company was $167,000 as of that date. During March 2017, the funds in escrow were paid to the Company while payments on the inventory were scheduled to be made through year-end 2017, according to a promissory note executed between the Company and the seller. The Company reserved the amounts due under the note during the first quarter of 2017. As of December 31, 2018, the Company had not received any further payments under the note.

There were no assets or liabilities associated with the discontinued operations in the consolidated balance sheet as of December 31, 2018. As of December 31, 2017, there were $35,000 of accrued expenses.

The following table represents the results of the discontinued operations for years ended December 31:

(6)	FINANCING ARRANGEMENTS

Private Placement of Preferred Stock

As of December 31, 2018, 95,500 shares of Series A Convertible Preferred Stock and 54,500 shares of Series A Exchangeable Preferred Stock, issued on June 8, 2011, in connection with a 2011 private placement (collectively, the "Preferred Stock"), are outstanding. The Company received an aggregate cash purchase price of $15,000,000, representing a per-share purchase price of $100 for the Series A Convertible Preferred Stock and $100 for the Series A Exchangeable Preferred Stock. The Company received net proceeds, after transaction costs and expenses, of $13,825,000.

The Preferred Stock has a par value of $0.001 per share and is convertible into common stock of the Company at a price of $2.389 per share. The Company can force conversion of all of the outstanding Preferred Stock if the closing price of its common stock meets certain share price, trading volume requirements, and other conditions. The stated value ($100 per share) of the Preferred Stock accretes at an annual rate of 7% compounded quarterly. While such accretion may be paid in cash at the Company's option, the Company's current loan agreement prohibits the payment of cash dividends. As of December 31, 2018, dividend accretion of $10,407,061 had accumulated on the Preferred Stock. The Preferred Stock is entitled to a liquidation preference equal to the greater of 100% of the total accreted value for each share of Preferred Stock, outstanding on the date of a liquidation, plus all accrued and unpaid dividends, or the amount a holder would have been entitled to had the holder converted the shares of Preferred Stock into common stock immediately prior to the liquidation. Accordingly, based upon the liquidation value of the Preferred Stock at December 31, 2018, there were 10,635,019 shares of common stock issuable upon conversion of the Preferred Stock. The Preferred Stock votes together with the common stock as if converted on the original date of issuance. Holders of Preferred Stock are entitled to purchase their pro rata share of additional stock issuances in certain future financings.

The Company can force conversion of all, and not less than all, of the outstanding Preferred Stock into Company common stock as long as the closing price of its common stock is at least 250% of the Conversion Price, or $5.9725 per common share, for at least 20 of the 30 consecutive trading days immediately prior to the conversion and the average daily trading volume is greater than 50,000 shares per day over the 30 consecutive trading days immediately prior to such conversion. The Company's ability to cause a conversion is subject to certain other conditions as provided pursuant to the terms of the Preferred Stock described above.

(8)	SHARE-BASED PAYMENT PLANS

On June 20, 2018, the Company's stockholders approved the CAS Medical Systems, Inc. 2018 Equity Incentive Plan (the "Plan"). The maximum number of shares of common stock that may be granted under the Plan is 2,500,000. Awards that may be granted under the Plan include options, restricted stock and restricted stock units, and other stock-based awards. The purposes of the Plan are to make available to our key employees and directors certain compensatory arrangements related to growth in value of our stock so as to generate an increased incentive to contribute to the Company's financial success and prosperity; to enhance the Company's ability to attract and retain exceptionally qualified individuals, whose efforts can affect the Company's financial growth and profitability; and to align, in general, the interests of employees and directors with the interests of our stockholders. As of December 31, 2018, there remained a total of 2,120,988 shares available for issuance pursuant to our equity incentive plans, including 44,812 shares remaining under the 2011 Equity Incentive Plan.

The Plan is administered by the Compensation Committee of the Board of Directors, which in turn determines the employees, officers, and directors to receive awards and the terms and conditions of these awards.

Weighted-average grant-date fair value of options granted during the year				$	0.79						$	0.72

During 2018, the Company granted non-qualified stock options to employees to purchase 87,500 shares of common stock at a weighted-average exercise price of $1.42. The stock options were granted at exercise prices based upon the Nasdaq official closing price on the date of each grant. The fair values of the options were estimated on the grant dates using the Black-Scholes option pricing model. Similar to other option pricing models, the Black-Scholes model requires the input of highly subjective assumptions which may materially affect the estimated fair value of the Company's stock options. The fair value of the stock options granted was $0.79 and assumed a weighted-average expected stock volatility of 56.3%, a weighted-average expected option term of 6.25 years, an average risk-free interest rate of 2.6%, and a 0.0% dividend yield. The risk-free interest rate approximated U.S. Treasury yields in effect at the time of the grant. The expected life of the stock options was determined using historical data adjusted for the estimated exercise dates of unexercised options. Volatility was determined using both current and historical implied volatilities of the underlying stock which are obtained from public data sources.

During 2018, stock options to purchase 53,824 shares of common stock were exercised, and options to purchase 368,676 shares were cancelled.

Additional information about stock options outstanding and exercisable at December 31, 2018, follows:

Restricted Stock

During 2018, members of the management team were granted 332,500 shares of restricted common stock, which primarily vest 25% per year on each anniversary of the grant date, and 90,000 restricted common shares were granted to outside members of the Board of Directors, which vest 50% per year on each anniversary of the grant date.

As of December 31, 2018, there were 1,202,562 restricted shares issued to employees, a consultant, and outside members of the Board of Directors, which remained issued and non-vested.

A summary of the restricted shares outstanding and changes for the years follow:

	2018			2017

Outstanding at beginning of year		1,107,250			418,500
Granted		422,500			798,250
Cancelled		—			(10,000	)
Vested		(327,188	)		(99,500	)
Outstanding at end of year		1,202,562			1,107,250

The fair value of the restricted common share grants has been calculated based upon the market value of the common stock on the date of issuance. Restricted stock granted to employees typically vests over a period of not less than three years, while restricted stock granted to members of the Board of Directors typically vests over a period of not more than two years from date of grant.

Stock compensation expense of $450,000 and $374,000 related to restricted shares was recorded for 2018 and 2017, respectively. The unamortized stock compensation expense associated with the restricted shares at December 31, 2018, was $1,233,000 and will be recognized through 2022.

Total stock compensation expense was $759,504 and $844,339 for 2018 and 2017, respectively.

Warrants

Warrants to purchase 472,782 shares of common stock at a weighted-average exercise price of $1.39 per share were outstanding at December 31, 2018. The warrants have an exercise price range of $0.38 to $1.98 per share. A total of 75,000 shares issued to former members of the board of directors have no expiration date. The balance of the outstanding warrants have been granted to the Company's current and former bank lenders and have expiration dates ranging from five to ten years from date of grant.

In connection with the Loan Agreement executed on May 8, 2018, the Company issued a warrant to the Lender, which provides for the right to purchase an aggregate of 218,194 shares of the Company's common stock for a five-year period, expiring on May 8, 2023, at an exercise price of $1.142 per share.

Stock Purchase Plan

The Company maintains an employee stock purchase plan. The CAS Medical Systems, Inc. Employee Stock Purchase Plan (the "Stock Purchase Plan") was approved by stockholders on June 10, 2009, and accordingly, 150,000 shares of common stock were reserved for issuance under the Stock Purchase Plan. The initial offering period began on July 1, 2009. As of December 31, 2018, there were 105,148 shares issued under the Stock Purchase Plan, and certain amounts had been withheld from employees' compensation to purchase an additional 8,778 shares which were issued during January 2019. The Stock Purchase Plan offers the Company's employees an opportunity to participate in a payroll-deduction-based program designed to incentivize them to contribute to the Company's success.

(9)	BENEFIT PLANS

The Company maintains a 401(k) benefit plan for its employees, which generally allows participants to make contributions via salary deductions up to allowable Internal Revenue Service limits on a tax-deferred basis. Such deductions may be matched in part by discretionary contributions by the Company. The matching contributions for 2018 and 2017 were $110,738 and $109,151, respectively.

(10)	INCOME TAXES

There are no current and deferred Federal and state income tax benefits for the years ended December 31, 2018 and 2017.

On December 22, 2017, the U.S. government enacted comprehensive tax reform legislation in the form of the Tax Cuts and Jobs Act of 2017 (the "Tax Act"). The Tax Act establishes new tax laws that affect 2017 and beyond. One of the principal new tax laws effective January 1, 2018, is the reduction of the U.S. Federal corporate income tax rate from 35% to 21%. As a result of the reduction in the Federal income tax rate, the Company revalued its net deferred tax assets as of December 31, 2017.

A reconciliation of U.S. Federal income taxes computed at the statutory rate to income taxes shown in the statement of operations for the years ended December 31, 2018 and 2017 follows:

	2018			2017

Income tax benefit at the statutory rate	$	(1,250,231	)	$	(2,540,040	)
State income taxes, net of Federal effect		(128,169	)		(33,130	)

Net deferred income tax assets and liabilities	$	—		$	—

The Company has performed the required analysis of both positive and negative evidence regarding the realization of its deferred income tax assets, including our past results of operations, recent cumulative losses, and our forecast for future taxable income. The assessment required the use of assumptions about future sales and pre-tax income, making allowance for uncertainties surrounding the rate of adoption of its products in the marketplace, competitive influences, and the investments required to increase market share in certain markets for its products. As of December 31, 2018, we have concluded that it is more likely than not that such deferred income tax assets will not be realized and, accordingly, have established a deferred income tax asset valuation allowance in the amount of $13,016,173.

F-16

The Company's Federal net operating loss carryforward of $42,089,000 is scheduled to expire beginning in 2031. State net operating loss carryforwards of $11,729,000 are scheduled to expire between 2028 and 2038. The amount of the net operating loss carryforwards that may be utilized annually to offset future taxable income and tax liabilities may be limited as a result of certain ownership changes pursuant to Section 382 of the Internal Revenue Code as well as limitations imposed by the Tax Act. The Company has not completed a study to determine if there have been one or more ownership changes due to the costs associated with such study.

The Company does not believe that there are unrecognized income tax benefits for December 31, 2018 or 2017, and expects no significant changes in 2019.

(11)	COMMITMENTS AND CONTINGENCIES

Product Litigation

The manufacture and sale of our products expose us to product liability claims and product recalls, including those which may arise from misuse or malfunction of, or design flaws in, our products or use of our products with components or systems not manufactured or sold by us. We are currently a defendant in a product liability action related to our former sleep apnea product line. Product liability claims, regardless of their ultimate outcome, could require us to spend significant time and money in litigation or to pay significant damages.

We believe that our product liability insurance is sufficient to cover any damages and costs that may be incurred, with respect to this matter.

Merger-Related Litigation

Operating Leases

The Company currently leases one corporate facility and certain equipment under non-cancellable operating leases. Rent expense under these leases was $353,000 in 2018 and $393,000 in 2017. Future annual minimum rental payments as of December 31, 2018, to the expiration of the leases follow:

2019	$	294,000
2020		291,000
2021		297,000
2022		25,000

Total	$	907,000

(12)	RECENT ACCOUNTING PRONOUNCEMENTS

In February 2016, the FASB issued ASU 2016-02, Leases - Topic 842. The amendment improves transparency and comparability among companies by recognizing lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. The new standard is effective for consolidated financial statements issued for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued.

The Company will apply the new guidance at the effective date of January 1, 2019. Management will also make an accounting policy election to not recognize on its balance sheet right-of-use assets and liabilities arising from short-term leases which are generally characterized as those leases less than one-year in length from commencement date. Management estimates that the adoption of the guidance will result in the recognition of additional right-of-use assets and lease liabilities for operating leases of approximately $863,000 as of January 1, 2019. The Company does not believe the guidance will have a material impact on its statements of operations.

F-17

In April 2016, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2016-10, Topic 606, Revenue from Contracts with Customers. ASU 2016-10 amends the revenue recognition standard it had issued in May 2014 (ASU 2014-09). The core principle of the guidance in Topic 606 is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which an entity is expected to be entitled in exchange for those goods and services. The amendments in ASU 2016-10 clarify the identification of performance obligations and the licensing implementation guidance. In adopting ASU 2016-10, the Company reviewed the five steps considered fundamental to determining when to recognize revenue. Those five steps are as follows: (1) Identify the contract(s) with a customer; (2) Identify the performance obligations in the contract; (3) Determine the transaction price; (4) Allocate the transaction price to the performance obligations in the contract; and (5) Recognize revenue when (or as) the entity satisfied a performance obligation.

The Company adopted the new revenue standard effective January 1, 2018, using the Modified Retrospective method, under which prior-year results are not restated; however, supplemental information regarding the impact of the new standard must be provided, if material. The standard, including the cumulative effect of its adoption, did not have a material impact on the Company's financial statements.

(13)	SUBSEQUENT EVENT

The Merger Agreement

On February 11, 2019, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which the Company would become a wholly-owned subsidiary of Edwards Lifesciences Corporation (the "Merger"). The Board of Directors of the Company has unanimously approved the Merger Agreement, the Merger, and the other transactions contemplated thereby.

As a result of the Merger, and at the effective time (the "Effective Time") each share of Company common stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive $2.45 per share in cash (the "Merger Consideration").

The Merger Agreement also provides that each holder of Company Series A Convertible Preferred Stock and Series A Exchangeable Preferred Stock shall provide a consent to convert such preferred stock, outstanding immediately prior to the Effective Time, into the right to receive the Merger Consideration as holders of the Company's common stock.

The Merger is subject to stockholder approval and certain additional customary closing conditions, including, among other things, the expiration of a required waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

The Merger Agreement contains certain termination rights for each party, including the right of the Company to terminate the Merger Agreement to accept a company superior proposal after complying with certain requirements. In addition, either party may terminate the Merger Agreement if the Merger is not consummated on or before November 8, 2019. The Merger Agreement further provides that the Company may be required to pay Edwards Lifesciences Holding, Inc. ("Edwards") a termination fee of $3.5 million under certain circumstances, including if Edwards terminates the Merger Agreement due to a change in the recommendation by the Company's Board of Directors for the Merger or due to the Company's material breach of its non-solicitation obligations set forth in the Merger Agreement. The Merger Agreement also provides that in case it is terminated by either Edwards or the Company following a failure to obtain the required vote of the Company's stockholders to adopt the Merger Agreement, the Company shall reimburse Edwards up to $1.0 million of certain of its transaction expenses, which would reduce on a dollar-for-dollar basis any termination fee otherwise owed to Edwards.

The Merger is expected to close during the second quarter of 2019 and is not subject to a financing condition.

Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company's Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based on the definition of "disclosure controls and procedures" in Rule 13a-15(e) of the Exchange Act. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Code of Ethics

Our Board of Directors has approved a Code of Ethics, in accordance with the rules of the Securities and Exchange Commission and Nasdaq, which governs the conduct of each of our directors and senior executive officers, including our principal executive officer, principal financial officer, principal accounting officer, and controller. Our Code of Ethics is maintained on our website at www.casmed.com. Any amendments to or waivers of the Code of Ethics that apply to our principal executive officer, principal financial officer, or principal accounting officer and that relates to any element of the definition of the term "code of ethics", as the term is defined by the Securities and Exchange Commission, will be posted on our website at www.casmed.com.

Nomination of Directors

The Nominating and Governance Committee assists the Board of Directors in identifying, screening, and reviewing individuals qualified to serve as directors in accordance with criteria approved by the Board and shall recommend to the Board candidates for nomination for election at the annual meeting of stockholders or to fill Board vacancies. The Nominating and Governance Committee develops and recommends to the Board and oversees implementation of our policies and procedures for the receipt of stockholder suggestions, regarding Board composition and recommendations of candidates for nomination by the Board. The full Board has adopted specifications applicable to members of the Board, and nominees for the Board must meet these specifications. The specifications provide that a candidate for director should:

●	Have a reputation for industry, integrity, honesty, candor, fairness, and discretion;

●	Be knowledgeable in his or her chosen field of endeavor, which field should have such relevance to our businesses as would contribute to the company's success;

●	Be knowledgeable, or willing and able to become so quickly, in the critical aspects of our businesses and operations; and

●	Be experienced and skillful in serving as a competent overseer of, and trusted advisor to, senior management of a publicly-held corporation.

In addition, nominees for the Board of Directors should contribute to the mix of skills, core competencies, and qualifications of the Board through expertise in one or more of the following areas: accounting and finance, the healthcare industry, international business, mergers and acquisitions, leadership, business and management, strategic planning, government relations, investor relations, executive leadership development, and executive compensation.

The Board of Directors also seeks nominees who will contribute to the Board's diversity. While the Board of Directors does not maintain a formulaic policy or approach with respect to diversity, it continually seeks a wide range of perspectives and experiences among its members.

The Board also considers nominees recommended by stockholders. Any recommendation must be in writing addressed to our Secretary and must include a detailed description of the business experience and other qualifications of the recommended nominee, as well as the signed consent of the nominee to serve if nominated and elected, so that the candidate may be properly considered. All stockholder recommendations are reviewed in the same manner as other potential candidates for board membership.

Board Information and Committees

The Board met eight times in 2018. Each director serving on the Board during 2018 attended at least 75% of the total number of Board meetings and meetings held by the Board committees on which he or she served during 2018. The Board has determined that each of our non-employee directors currently serving on the Board or who served on the Board during 2018 is independent based upon the criteria provided by Nasdaq rules. Members of the Board serve on one or more of the committees described below, except for directors who are also employees of CASMED.

Pursuant to the terms of the June 2011 Investment Agreement among the Company, Thomas, McNerney & Partners, L.P., and certain affiliates of Thomas, McNerney & Partners, L.P., two of the members of our seven-member Board of Directors tendered their resignations, and the purchasers nominated James E. Thomas and Kathleen A. Tune (the "Purchaser Designees") to serve as members of our Board of Directors as of the closing. Pursuant to the Investment Agreement, the purchasers' right to nominate the Purchaser Designees shall at no time be in excess of the level considered proportionate for purposes of the Nasdaq listing rules or other applicable listing rules. Mr. Thomas and Ms. Tune are currently serving as the Purchaser Designees.

- 33 -

Since June 2011, the Board of Directors has operated without a formal chairman. In April 2012, Mr. Thomas was appointed as our lead director, although all directors have input into the preparation of the meeting agenda and topics of board discussion and oversight. The Board of Directors believes that this is an appropriate structure for the overall governance of the Board.

The Board of Directors has general risk oversight responsibilities. The Board believes that its structure enables it to effectively oversee risk management.

The Board has standing Audit, Compensation, and Nominating and Governance Committees. Further information regarding these committees is provided below.

The Audit Committee, which met five times in 2018, monitors our financial reporting standards and practices and our internal financial controls to ensure compliance with the policies and objectives established by the Board of Directors. The committee directly retains and recommends for stockholder approval an independent accounting firm to conduct the annual audit and discusses with our independent accountants the scope of their examinations, with particular attention to areas where either the committee or the independent accountants believe special emphasis should be directed. The committee reviews the quarterly and annual financial statements and the annual independent accountants' report, invites the accountants' recommendations on internal controls and on other matters, and reviews the evaluation given and corrective action taken by management. It reviews the independence of the accountants and pre-approves audit and permissible non-audit services. It has primary oversight responsibility for our Compliance Program. Members of the committee are Paul Molloy, Kathleen Tune, and Kenneth Weisshaar. Mr. Weisshaar chairs the committee. Each member of the committee is independent as defined in Rule 10A-3 of the Securities and Exchange Commission and the listing standards of Nasdaq. The Board of Directors has determined that each of Paul Molloy, Kathleen Tune, and Kenneth Weisshaar qualifies as an "audit committee financial expert", as that term is defined in Regulation S-K of the Securities and Exchange Commission.

The Compensation Committee, which met four times in 2018, oversees our executive and director compensation programs and policies and annually reviews all components of compensation to ensure that our objectives are appropriately achieved. These functions are not delegated to our officers or to third-party professionals, although the committee may from time to time retain third-party consultants to provide advice regarding compensation issues. No such consultants were retained during 2018. The committee also considers input from our executive officers, although final decisions regarding executive compensation are made by the committee. The committee is also responsible for certain administrative aspects of our compensation plans and stock plans and approves or recommends changes in these plans. It also approves performance targets and grants under our incentive plans and our stock plan for our executive officers. The committee also reviews officers' potential for growth and, with the chief executive officer, will be responsible for succession planning. The members are Gregory Rainey, James Thomas, and Alan Milinazzo. Mr. Thomas is chairman of the committee. All members serving on the Compensation Committee during 2018 were independent, based upon the criteria provided by Nasdaq rules.

The Nominating and Governance Committee, which met once in 2018, reviews, on a periodic basis, the overall effectiveness and/or appropriateness of our corporate governance and recommends improvements when necessary; assists the Board in identifying, screening, and reviewing individuals qualified to serve as directors in accordance with criteria approved by the Board and shall recommend to the board candidates for nomination for election at the annual meeting of stockholders or to fill board vacancies; develops and recommends to the Board and oversees implementation of our policies and procedures for the receipt of stockholder suggestions regarding board composition and recommendations of candidates for nomination by the Board; and assists the Board in disclosing information relating to functions of the committee as may be required in accordance with the Federal securities laws. Members of the committee are Gregory Rainey, James Thomas, and Kenneth Weisshaar. Mr. Rainey is the chairman of the committee. All members serving on the committee during 2018 were independent, based upon the criteria provided by Nasdaq rules.

Each committee is governed by a written charter. Copies of each committee charter are available on our website at www.casmed.com.

Item 11. Executive Compensation

Compensation Discussion and Analysis

Our Compensation Committee, which is comprised of three independent non-employee directors, has formulated a compensation philosophy that is designed to enable us to attract, retain, and reward capable employees who can contribute to the success of the Company, principally through a combination of (1) base salaries, (2) annual incentive opportunities, and (3) longer-term incentive opportunities for senior management. We believe that implementation of a system of compensation that emphasizes performance-based compensation provides a strong alignment to stockholders' interests. Five key principles serve as the guiding framework for compensation decisions for all executive officers of CASMED:

· To attract and retain the most highly qualified management and employee team;

· To pay competitively, compared to similar companies in our industry;

· To encourage superior employee performance by aligning rewards with stockholder interests;

· To motivate senior executives to achieve CASMED's annual and long-term business goals by providing equity-based incentive opportunities; and

· To strive for fairness in administration by emphasizing performance-related contributions as the basis for pay decisions.

To implement these policies, we have designed the framework for a four-part executive compensation program consisting of base salary, annual incentives, long-term incentive opportunities for senior management, and other employment benefits.

Base Salary. We will seek to maintain levels of compensation that are competitive with similar companies in our industry. Base salary represents the fixed component of the executive compensation program. CASMED's philosophy regarding base salaries is to maintain salaries for the aggregate officer group at or near the competitive industry average. Periodic increases in base salary will relate to individual contributions evaluated against established objectives, length of service, and the industry's annual competitive pay practice movement. We believe that base salary for 2018 for our Chief Executive Officer and for the other executive officers was generally at the competitive industry average.

Annual Incentive Program. During February 2018, the Compensation Committee approved the 2018 management annual incentive program which includes various targets, including sales, adjusted cash flow from operations, and personal goals. Total bonus payments of approximately $730,000 (exclusive of tax obligations) would be payable to the management team, including the named executive officers, upon achieving 100% of the targets, payable in either cash or vested common stock. The program provides for reduced payouts at certain achievement levels below 100% as well as increased payouts for performance above target up to a capitated level. The actual payment to management for 2018 approximates $735,000, which is to be paid during 2019.

Certain of our executive officers, including Messrs. Patton, Baird, Gamelin, and Benni, are also eligible to receive supplemental lump-sum cash transaction bonus payments upon closing of a change of control transaction. In order to be eligible for the transaction bonus, each executive generally must remain employed through the proposed merger. The amounts to which each executive officer will be eligible are as follows: Mr. Patton ($325,000); Mr. Baird ($240,000); Mr. Gamelin ($220,000); and Mr. Benni ($75,000).

During February 2019, the Compensation Committee approved the 2019 management annual incentive program, which is based upon achieving certain revenue targets. Total cash bonus payments of approximately $690,000 (exclusive of tax obligations) would be payable to the management team including the named executive officers upon achieving 100% of the target. The program provides for reduced payouts at certain achievement levels below 100% as well as increased payouts for performance above target up to a capitated level.

- 35 -

The Compensation Committee also assesses whether to pay discretionary bonuses to our employees, including senior executives, either in cash or stock, based upon performance. Payment of the performance bonuses is at the sole discretion of the Compensation Committee and is not based on specific metrics, although the Compensation Committee bases its decisions on numerous factors, including overall corporate and personal performance. No additional discretionary cash bonus payments were made to the named executive officers for 2017 or 2018.

Long-Term Incentives. We believe that long-term incentives should provide senior executives with an opportunity to increase their ownership and potentially gain financially from CASMED stock price increases. By this approach, the best interests of stockholders and senior executives will be closely aligned. Therefore, senior executives are eligible to receive restricted stock and stock options (which give them the right to purchase shares of common stock at a specified price in the future). These grants will vest based upon the passage of time, the achievement of performance metrics, or both. We believe that the use of restricted stock and stock options as the basis for long-term incentive compensation meets our defined compensation strategy and business needs by achieving increased value for stockholders and retaining key employees.

Other Benefits. Our philosophy is to provide competitive health and welfare benefits to executives and employees but to maintain a conservative posture relative to executive benefits. We do provide life insurance and supplemental disability insurance to certain of our senior executive officers.

Executive Contracts and Severance and Change of Control Arrangements

Thomas M. Patton. On August 27, 2010, we entered into an employment agreement with Thomas M. Patton, our President and Chief Executive Officer. Under the terms of the agreement, Mr. Patton is employed on an "at will" basis, will receive an annual base salary of $358,225, and will be eligible for an annual bonus in the form of cash or CASMED common stock, as determined at the sole discretion of the Compensation Committee of the Board. Accordingly, Mr. Patton will be eligible for a performance-based bonus for 2019 equal to 50% of his annual salary if certain targets are achieved.

As an inducement to cause Mr. Patton to accept employment with the Company, Mr. Patton was granted a ten-year, non-qualified stock option to purchase 350,000 shares of our common stock at an exercise price of $2.10 per share, the closing price of our common stock on Nasdaq upon the effective date of the agreement. Such stock options vested in equal monthly installments over a period of four years from date of grant. As a further inducement to consummate Mr. Patton's employment, Mr. Patton was granted 250,000 shares of restricted common stock of CASMED on the same date. Such restricted shares vested over a period of four years from date of grant.

Director Compensation

Director Fees. During 2018, we paid our non-employee directors an annual retainer of $30,000, payable in quarterly installments. We also paid an additional annual retainer of $5,000 to the Audit Committee chairman, payable in quarterly installments. During 2018, we incurred total fees of $155,000 to the non-employee directors as a group for their participation as Board and committee members. Fees of $30,000 payable to Mr. Thomas as a member of the Board of Directors were accrued, at his direction, to Thomas, McNerney & Partners II, LLC.

Our non-employee directors are eligible to receive options, restricted stock, and other equity-linked grants under our 2011 and 2018 equity incentive plans.

(a)

Based upon information set forth in a Form 4 filed with the SEC on February 13, 2015, by Thomas McNerney & Partners II, L.P. ("TMP II LP"); TMP Nominee II, LLC ("TMPN"); TMP Associates II, L.P. ("TMPA"); and Thomas, McNerney & Partners II, LLC ("TMP II LLC"). Also based upon information set forth in a Schedule 13D/A Amendment No. 3 filed with the SEC on February 13, 2019, by TMP II LP, TMPN, TMPA, TMP II LLC, and Mr. James Thomas, and other data available to CASMED. TMP II LP, TMPN, and TMPA hold, respectively, 94,182; 984; and 334 shares of Series A Convertible Preferred Stock (which represent in the aggregate 100% of the outstanding Series A Convertible Preferred Stock) and 53,748; 561; and 191 shares of Series A Exchangeable Preferred Stock (which represent in the aggregate 100% of the outstanding Series A Exchangeable Preferred Stock). The shares in the table above, with respect to common stock, include "common stock equivalent" rights on shares of Series A Convertible Preferred Stock and Series A Exchangeable Preferred Stock. Each share of Series A Convertible Preferred Stock and Series A Exchangeable Preferred Stock has "common stock equivalent" rights as of February 11, 2019, equal to approximately 71.5 shares of common stock, which is determined by dividing the stated value of $100 per share of Series A Convertible Preferred Stock and Series A Exchangeable Preferred Stock plus accretion by an effective conversion price of $2.389 per share. Of the 10,721,871 common stock equivalent rights in the table above (i) 10,573,909 are deemed owned directly by TMP II LP, (ii) 110,436 are owned directly by TMPN, and (iii) 37,526 are directly owned by TMPA. Data reflects accretion of dividends as of February 11, 2019. TMP II LLC, the general partner of TMP II LP and TMPA, has shared voting and dispositive power over the shares held by TMP II LP and TMPA. In addition, TMPN has entered into an agreement with TMP II LLC that directs TMPN to vote and dispose of securities in the same manner as directed by TMP II LLC with respect to the shares held by TMP II LP and TMPA. Mr. Thomas is the manager of TMPN and has voting and dispositive power over such securities, provided that they are obligated to exercise such power in the same manner as TMP II LLC votes and disposes of the securities of CASMED over which TMP II LLC exercises voting and dispositive power. Mr. Thomas is the manager of TMP II LLC. The persons and entities named in this footnote are referred to individually herein as a "Reporting Person" and collectively as the "Reporting Persons." Amounts in the table above also include 63,454 shares of common stock and options to purchase 65,000 shares of common stock held by Mr. Thomas and 20,954 shares of common stock and options to purchase 65,000 shares of common stock held by Ms. Kathleen A. Tune, directors of CASMED, which shares and options are held in their respective names but are being held for the benefit of TMP II LP. Each Reporting Person disclaims beneficial ownership of the above-referenced shares other than to the extent of their pecuniary interest therein.

All Other Fees

CohnReznick LLP did not provide services in addition to those described above during the years ended December 31, 2018 and 2017.

Audit Committee Pre-Approval Policy

The Audit Committee operates under a written charter. Under this charter, the Audit Committee is responsible for selecting, approving, compensating, and overseeing the independence, qualifications, and performance of the independent accountants. Further, the Audit Committee has adopted a pre-approval policy pursuant to which certain permissible non-audit services may be provided by the independent accountants. Pre-approval is generally provided for up to one year and may be detailed as to the particular service or category of services and may be subject to a specific budget. The Audit Committee may also pre-approve particular services on a case-by-case basis. In assessing requests for services from the independent accountants by management, the Audit Committee considers whether such services are consistent with the auditor's independence, whether the independent accountants are likely to provide the most effective and efficient service based upon their familiarity with the company, and whether the service could enhance our ability to manage or control risk or improve audit quality.

Notwithstanding the pre-approval policy, all of the audit-related, tax, and other services provided by CohnReznick LLP in calendar year 2018 were approved in advance by the Audit Committee.
