Overview

We are a global healthcare leader for developing

and producing stabilized hypochlorous acid, or HOCl, products for a wide range of applications, including wound care, eye care, oral care,

dermatological conditions, podiatry, animal health care and non-toxic disinfectants. Our products are clinically proven to reduce itch,

pain, scarring, and irritation safely and without damaging healthy tissue. In-vitro and clinical studies of HOCl show it to safely manage

skin abrasions, lacerations, minor irritations, cuts, and intact skin. We sell our products either directly or via partners in 55 countries

worldwide.

Business Update

Over the past year, we have continued our focus

on growing our revenues while maintaining costs. Our human care revenues have grown as a result of adding new customers and distributors,

and through organic growth from existing customers and distributors. We have also focused on introducing new products into multiple markets

around the world and increasing our regulatory reach by seeking new approvals and clearances.

Some of our recent business updates include:

We continue to invest in research and development,

both in the U.S. and internationally, for our core performance-stabilized hypochlorous acid, or HOCl, technology. We have an active pipeline

of products and we continue to seek new regulatory clearances to expand potential markets we can sell our products into.

Business Channels

Our core market differentiation is based on being

the leading developer and producer of stabilized hypochlorous acid, or HOCl, solutions. We have been in business for over 20 years, and

in that time, we have developed significant scientific knowledge of how best to develop and manufacture HOCl products backed by decades

of studies and data collection. HOCl is known to be among the safest and most-effective ways to relieve itch, inflammation and burns while

stimulating natural healing through increased oxygenation and eliminating persistent microorganisms and biofilms.

We sell our products into many markets both in

the U.S. and internationally. In international markets, we ship a variety of products to 55 countries. Our core strategy is to work with

partners both in the United States and around the world to market and distribute our products. In some cases, we market and sell our own

products.

Dermatology

We have developed unique, differentiated, prescription-strength

and safe dermatologic products that support paths to healing among various key dermatologic conditions. Our products are primarily targeted

at the treatment of redness and irritation, the management of scars and symptoms of eczema/atopic dermatitis. We are strategically focused

on introducing innovative new products that are supported by human clinical data with applications that address specific dermatological

procedures currently in demand. In addition, we look for markets where we can provide effective product line extensions and pricing to

new product families.

In the United States, we partner with EMC Pharma,

LLC to sell our prescription dermatology products. Pursuant to our March 2021 agreement with EMC Pharma, we manufacture products for EMC

Pharma and EMC Pharma has the right to market, sell and distribute them to patients and customers for an initial term of five years, subject

to meeting minimum purchase and other requirements.

In September

2021, we launched a new over-the-counter product, Regenacyn® Advanced Scar Gel, which is clinically proven to improve the overall

appearance of scars while reducing pain, itch and redness. On the same day, we launched Regenacyn® Plus, a prescription-strength scar

gel which is available as an office dispense product through physician offices.

In October

2022, we launched two new over-the-counter dermatology products in the United States, Reliefacyn® Advanced Itch-Burn-Rash-Pain Relief

Hydrogel for the alleviation of red bumps, rashes, shallow skin fissures, peeling, and symptoms of eczema/atopic dermatitis, and Rejuvacyn®

Advanced Skin Repair Cooling Mist for management of minor skin irritations following cosmetic procedures as well as daily skin health

and hydration.

In June 2022, the Natural Products Association

certified Rejuvacyn Advanced as a Natural Personal Care Product. Reliefacyn Advanced received the National Eczema Association Seal of

AcceptanceTM in 2023.

In January 2023, we launched a line of office

dispense products exclusively for skin care professionals, including two new prescription strength dermatology products, Reliefacyn® Plus

Advanced Itch-Burn-Rash-Pain Relief Hydrogel and Rejuvacyn® Plus Skin

Repair Cooling Mist. These products, along with Regenacyn® Plus Scar Gel, are

marketed and sold directly to dermatology practices and medical spas.

In January

2024, we launched LumacynTM Clarifying Mist, a direct-to-consumer skin care product in the United States. Lumacyn is an all-natural

daily toner to soothe skin, reduce redness and irritation, and manage blemishes by reducing infection.

Our consumer products are available

through Amazon.com, our online store and third-party distributors.

We sell dermatology products in Europe and Asia

through distributors. In these international markets, we have a network of partners, ranging from country specific distributors to large

pharmaceutical companies to full-service sales and marketing companies. We work with our international partners to create products they

can market in their home country. Some products we develop and manufacture are custom label while others use branding we have already

developed. We have created or co-developed a wide range of products for international markets using our core HOCl technology.

First Aid and Wound Care

Our HOCl-based wound care products are intended

for the treatment of acute and chronic wounds as well as first- and second-degree burns, and as an intraoperative irrigation treatment.

They work by first removing foreign material and debris from the skin surface and moistening the skin, thereby improving wound healing.

Secondly, our HOCl products assist in the wound healing process by removing microorganisms. HOCl is an important constituent of our innate

immune system, formed and released by the macrophages during phagocytosis. Highly organized cell structures such as human tissue can tolerate

the action of our wound care solution while single-celled microorganisms cannot, making our products advantageous to other wound-irrigation

and antiseptic solutions. Due to its unique chemistry, our wound treatment solution is also much more stable than similar products on

the market and therefore maintains much higher levels of hypochlorous acid over its shelf life.

In the United States, we sell our wound care products

directly to hospitals, physicians, nurses, and other healthcare practitioners and indirectly through non-exclusive distribution arrangements.

In Europe, the Middle East and Asia, we sell our wound care products through a diverse network of distributors.

To respond to market demand for our HOCl technology-based

products, we launched our first direct to consumer over-the-counter product in the United States in February 2021. Microcyn® OTC Wound

and Skin Cleanser is formulated for home use without prescription to help manage and cleanse wounds, minor cuts, and burns, including

sunburns and other skin irritations. Microcyn OTC is available without prescription through Amazon.com, our online store and third-party

distributors.

In March 2021, we received approval to market

and use our HOCl products as biocides under Article 95 of the European Biocidal Products Regulation in France, Germany and Portugal. The

approval applies to our products MucoClynsTM for human hygiene to be marketed and commercialized by us, MicrocynAH® for animal

heath marketed and commercialized through our partner, Petagon Limited, and MicroSafe for disinfectant use to be marketed and commercialized

through our partner, MicroSafe Group DMCC.

In June 2022, the Natural Products Association

certified Microcyn OTC as a Natural Personal Care Product in the United States.

In June 2023, we announced a new application of

our HOCl technology for intraoperative pulse lavage irrigation treatment, which can replace commonly used IV bags in a variety of surgical

procedures. The intraoperative pulse lavage container is designed to be used in combination with a pulse lavage irrigation device, or

flush gun, for abdominal, laparoscopic, orthopedic, and periprosthetic procedures. It is in trial use by hospitals in Europe and launched

in the U.S. in November 2023.

On April 9, 2024, we announced expansion of our

Microcyn® Negative Pressure Wound Therapy Solution products line, now available in 250mL, 450mL and 990mL sizes to meet the diverse

needs of healthcare professionals and patients.

Eye Care

Our prescription product

AcuicynTM is an antimicrobial prescription solution for the treatment of blepharitis and the daily hygiene of eyelids and lashes

and helps manage red, itchy, crusty and inflamed eyes. It is strong enough to kill the bacteria that causes discomfort, fast enough to

provide near instant relief, and gentle enough to use as often as needed. In the United States, our partner EMC Pharma sells Acuicyn through

its distribution network.

In international markets

we rely on distribution partners to sell our eye products. In May 2020, we entered into an expanded license and distribution agreement

with our existing partner, Brill International S.L. for our Microdacyn60® Eye Care HOCl-based product. Under the license and distribution

agreement, Brill has the right to market and distribute our eye care product under the private label OcudoxTM in Italy, Germany,

Spain, Portugal, France, and the United Kingdom for a period of 10 years, subject to meeting annual minimum sales quantities. In return,

Brill paid us a one-time fee, and the agreed upon supply prices. In parts of Asia, Dyamed Biotech markets our eye product under the private

label Ocucyn.

In September 2021, we

launched Ocucyn® Eyelid & Eyelash Cleanser, which is sold directly to consumers on Amazon.com, through our online store, and through

third party distributors. Ocucyn® Eyelid & Eyelash Cleanser, designed for everyday use, is a safe, gentle, and effective solution

for good eyelid and eyelash hygiene.

Oral, Dental and Nasal Care

We sell

a variety of oral, dental, and nasal products around the world.

In international markets, our product Microdacyn60®

Oral Care treats mouth and throat infections and thrush. Microdacyn60 assists in reducing inflammation and pain, provides soothing cough

relief and does not contain any harmful chemicals. It does not stain teeth, is non-irritating, non-sensitizing, has no contraindications

and is ready for use with no mixing or dilution.

Our international nasal care product SinudoxTM

based on our HOCl technology is an electrolyzed solution intended for nasal irrigation. Sinudox clears and cleans stuffy, runny noses

and blocked or inflamed sinuses by ancillary ingredients that may have a local antimicrobial effect. Sinudox is currently sold through

Amazon in Europe. In other parts of the world, we partner with distributors to sell Sinudox.

Podiatry

Our HOCl-based wound care products are also indicated

for the treatment of diabetic foot ulcers. In the United States, we sell our wound care products directly to podiatrists as well as hospitals,

nurses, and other healthcare practitioners and indirectly through non-exclusive distribution arrangements. In Europe, we sell our wound

care products for podiatric use through a diverse network of distributors.

On April 11, 2023, we launched PodiacynTM

Advanced Everyday Foot Care direct to consumers for over-the-counter use in the United States, intended for management of foot odors,

infections, and irritations, as well as daily foot health and hygiene. Podiacyn is available through Amazon.com, our online store and

third-party distributors.

Animal Health Care

MicrocynAH® is an HOCl-based topical product

that cleans, debrides and treats a wide spectrum of animal wounds and infections. It is intended for the safe and rapid treatment of a

variety of animal afflictions including cuts, burns, lacerations, rashes, hot spots, rain rot, post-surgical sites, pink eye symptoms

and wounds to the outer ear.

For our animal health products sold in the U.S.

and Canada, we partner with Compana Pet Brands. Compana distributes non-prescription products to national pet-store retail chains and

farm animal specialty stores, such as PetSmart, Tractor Supply, Cabela’s, PetExpress, Bass Pro Shops, and Menards. In August 2022,

we announced the launch of a MicrocynVS® line of products exclusively for veterinarians for the management of wound, skin,

ear and eye afflictions in all animal species.

For the

Asian and European markets, in May 2019 we partnered with Petagon an international importer and distributor of quality pet food and products

for an initial term of five years. We supply Petagon with all MicrocynAH products sold by Petagon. In August 2020, Petagon received a

license from the People’s Republic of China for the import of veterinary drug products manufactured by us. This is the highest classification

Petagon and Sonoma can receive for animal health products in China.

Surface Disinfectants

Our HOCl technology has been formulated as a disinfectant

and sanitizer solution for our partner MicroSafe and is sold in numerous countries. It is designed to be used to spray in aerosol format

in areas and environments likely to serve as a breeding ground for the spread of infectious disease, which could result in epidemics or

pandemics. The medical-grade surface disinfectant solution is used in hospitals worldwide to protect doctors and patients. In May 2020,

Nanocyn® Disinfectant & Sanitizer received approval to be entered into the Australian Register of Therapeutic Goods, or ARTG for

use against the coronavirus SARS-CoV-2, or COVID-19, and was also authorized in Canada for use against COVID-19. Nanocyn has also met

the stringent environmental health and social/ethical criteria of Good Environmental Choice Australia, or GECA, becoming one of the very

few eco-certified, all-natural disinfectant solutions in Australia.

Through our partner MicroSafe, we sell hard surface

disinfectant products into Europe, the Middle East and Australia.

In July 2021, we granted MicroSafe the non-exclusive

right to sell and distribute Nanocyn in the United States provided that MicroSafe secure U.S. EPA approval. In April of 2022, MicroSafe

secured the EPA approval for Nanocyn® Disinfectant & Sanitizer, meaning that it can now be sold in the United States as a surface

disinfectant, and it was subsequently added to the EPA’s list N for use against COVID-19. In June 2022, the EPA added Nanocyn to

List Q as a disinfectant for Emerging Viral Pathogens, including Ebola virus, Mpox, and SARS-CoV-2, and in March 2023 the EPA added Nanocyn

to Lists G and H, for use against Methicillin Resistant Staphylococcus Aureus (MRSA), Salmonella, Norovirus, Poliovirus, and as a fungicide.

Nanocyn also received the Green Seal® Certification after surpassing a series of rigorous standards that measure environmental

health, sustainability and product performance. Nanocyn is currently sold by MicroSafe in Europe, the Middle East and Australia.

Employees

As of June 17, 2024, we employed a total of 9

full-time employees in the United States, and one full-time employee in the Netherlands. Additionally, we had 162 employees in Mexico.

We are not a party to any collective bargaining agreements. We believe relations with employees are very good.

When fumigated, Nanocyn has demonstrated the ability

to kill a wide range of airborne pathogens and significantly reduce the spread of infectious disease.

Research and Development

Research and development expenses consist primarily

of expenses for clinical studies, personnel, regulatory services and supplies. For the years ended March 31, 2024 and 2023, research and

development expense amounted to $1,871,000 and $207,000, respectively. A small percentage of these expenses were borne by our customers.

We manufacture all of our products at our facility

in Zapopan, Mexico. We have developed a manufacturing process and conduct quality assurance testing on each production batch in accordance

with current U.S., Mexican and international Current Good Manufacturing Practices. Our facility is required to meet and maintain regulatory

standards applicable to the manufacture of pharmaceutical and medical device products and is certified and complies with U.S. Current

Good Manufacturing Practices, Quality Systems Regulations for medical devices, and International Organization for Standardization, or

ISO, guidelines. Our facility has been approved by the Ministry of Health and is also ISO 13485 certified.

Our machines are tested regularly, which is part

of a validation protocol mandated by U.S., Mexican and international Current Good Manufacturing Practices, Quality Systems Regulation,

and ISO requirements. This validation is designed to ensure that the final product is consistently manufactured in accordance with product

specifications at all manufacturing sites. Certain materials and components used in manufacturing are proprietary to Sonoma. All other

raw materials and supplies utilized in the manufacturing process of our products are available from various third-party suppliers in quantities

adequate to meet our needs.

We believe we own sufficient factory space and

equipment to produce an adequate amount of product to meet anticipated future requirements for at least the next two years. With expansion

into new geographic markets, we may establish additional manufacturing facilities to better serve those new markets.

Regulatory Approvals and Clearances

To date, in the United States we have obtained

21 U.S. Food and Drug Administration, or FDA, clearances permitting the sale of products as medical devices for Section 510(k) of the

Federal Food, Drug and Cosmetic Act.

Outside the United States, we sell products for

dermatological and advanced tissue care with a European Conformity marking, Conformité Européenne, or CE. On April 9, 2020,

we received an updated CE certificate covering 39 products in 54 countries with various approvals in Brazil, China, Southeast Asia, South

Korea, India, Australia, New Zealand, and the Middle East.

The following table summarizes

our current material regulatory approvals and clearances by brand.

Brand Approval Type Summary Indication

HOCl-based Products:

Significant Customers

We rely on certain key customers for a significant

portion of revenues. At March 31, 2024, customer B represented 13% of our net accounts receivable balance and customer D represented 17%

of our net accounts receivable balance. At March 31, 2023, customer B represented 22% of our net accounts receivable balance and customer

D represented 21% of our net accounts receivable balance. For the year ended March 31, 2024, customer A represented 17%, customer B represented

15% and customer C represented 14% of net revenues. For the year ended March 31, 2023, customer A represented 11%, customer B represented

16% and customer C represented 18% of net revenues.

Intellectual Property

Our success depends in part on an ability to obtain

and maintain proprietary protection for product technology and know-how, to operate without infringing proprietary rights of others, and

to prevent others from infringing on our proprietary rights. We seek to protect a proprietary position by, among other methods, filing,

when possible, U.S. and foreign patent applications relating to our technology, inventions and improvements that are important to the

business. We have patented certain aspects of our HOCl technology in the United States and worldwide. We also rely on trade secrets, know-how,

continuing technological innovation, and in-licensing opportunities to develop and maintain a proprietary position.

Although we work diligently to protect proprietary

technology, there are no assurances that any patent will be issued from currently pending patent applications or from future patent applications.

The scope of any patent protection may not exclude competitors or provide competitive advantages, and any patent may not be held valid

if subsequently challenged, and others may claim rights in or ownership of patents and proprietary rights. Furthermore, others may develop

products similar to ours and may duplicate any of the products or design around patents.

We have also filed for trademark protection for

marks used with products in each of the following regions: United States, Europe, Canada, certain countries in Central and South America,

including Mexico and Brazil, certain countries in the Middle East and certain countries in Asia, including Japan, China, Hong Kong, the

Republic of Korea, India and Australia. In addition to patents and trademarks, we rely on trade secret and other intellectual property

laws, nondisclosure agreements and other measures to protect intellectual property rights. We believe that in order to have a competitive

advantage, we must develop and maintain the proprietary aspects of technologies. Employees, consultants and advisors are required to execute

confidentiality agreements in connection with their employment, consulting or advisory relationships. Employees, consultants and advisors

with whom we expect to work with are also required to disclose and assign to us all inventions made in the course of a working relationship

with them, while using intellectual property or which relate to our business. Despite any measures taken to protect our intellectual property,

unauthorized parties may attempt to copy aspects of the products or to wrongfully obtain or use information that is regarded as proprietary.

Competition

We compete globally across six main channels:

dermatology, eye, nasal and oral care, wound and acute care, podiatry, animal health care and surface disinfectants with our HOCl technology.

Dermatology

Our dermatology products are at the forefront

of HOCl-based solutions, a safe and highly effective active ingredient designed to relieve itching and burning and act as a highly effective

antimicrobial agent. We believe no other solutions on the market provide the same patient benefits at the levels of safety and cost. Our

HOCl-based solutions face significant competition in the United States from prescription products including corticosteroids, topical steroids

and topical antibiotics. Our opportunity as an adjunct to these steroids is based on the insight that many doctors and patients limit

steroid and antibiotic use due to potential side effects. These side effects include bacterial resistance, stinging, burning and inflammation

for topical antibiotics and stretch marks, easy bruising, tearing of the skin and, to a lesser extent, enlarged blood vessels for topical

steroids. Our HOCl-based products are safe, non-toxic and have shown few side effects in clinical studies.

Wound and Acute Care Markets

Similar to our dermatology products, our HOCl-based

wound and acute care solutions provide improved efficacy at lower costs than traditional acute care products. Our HOCl-based solutions

compete with topical anti-infectives and antibiotics, as well as some advanced wound technologies, such as skin substitutes, growth factors

and delayed release silver-based dressings. Our opportunity in this space relative to antibiotics is based on the insight that competing

antibiotic solutions may have resistance-building properties.

Factors Affecting Competitive Position

While some other companies are able to produce

small molecule, HOCl-based formulations, based on our research, their products may become unstable after a relatively short period of

time or have large ranges of effectiveness. We believe our HOCl-based solutions are among the most stable therapeutics available.

Some of our competitors in the dermatology, wound

care, eye, nasal and oral care, podiatry, animal health care and surface disinfectant markets enjoy several competitive advantages. These

include:

· greater name recognition;

· established distribution networks;

Government Regulation

Government authorities in the United States, at

the federal, state and local levels, and foreign countries extensively regulate, among other things, the research, development, testing,

manufacture, labeling, promotion, advertising, distribution, sampling, marketing, and import and export of pharmaceutical products, biologics

and medical devices. All of our products in development will require regulatory approval or clearance by government agencies prior to

commercialization. In particular, human therapeutic products are subject to rigorous pre-clinical and clinical trials and other approval

procedures of the FDA and similar regulatory authorities in foreign countries. Various federal, state, local and foreign statutes and

regulations also govern testing, manufacturing, safety, labeling, storage, distribution and record-keeping related to such products and

their marketing. The process of obtaining these approvals and clearances, and the subsequent process of maintaining substantial compliance

with appropriate federal, state, local, and foreign statutes and regulations, require the expenditure of substantial time and financial

resources. In addition, statutes, rules, regulations and policies may change and new legislation or regulations may be issued that could

delay such approvals.

Medical Device Regulation

To date, we have received 21 510(k) clearances

for use of products as medical devices in tissue care management, such as cleaning, debridement, lubricating, moistening and dressing,

including for acute and chronic wounds, and in dermatology applications. Any future product candidates or new applications classified

as medical devices will require clearance by the FDA.

Medical devices are subject to FDA clearance and

extensive regulation under the Federal Food Drug and Cosmetic Act. Under the Federal Food Drug and Cosmetic Act, medical devices are classified

into one of three classes: Class I, Class II or Class III. The classification of a device into one of these three classes generally depends

on the degree of risk associated with the medical device and the extent of control needed to ensure safety and effectiveness. Devices

may also be designated unclassified. Unclassified devices are legally marketed pre-amendment devices for which a classification regulation

has yet to be finalized and for which a pre-market approval is not required.

Class I devices are devices for which safety and

effectiveness can be assured by adherence to a set of general controls. These general controls include compliance with the applicable

portions of the FDA’s Quality System Regulation, which sets forth good manufacturing practice requirements; facility registration,

device listing and product reporting of adverse medical events; truthful and non-misleading labeling; and promotion of the device only

for its cleared or approved intended uses. Class II devices are also subject to these general controls, and any other special controls

as deemed necessary by the FDA to ensure the safety and effectiveness of the device. Review and clearance by the FDA for these devices

is typically accomplished through the 510(k) pre-market notification procedure. When 510(k) clearance is sought, a sponsor must submit

a pre-market notification demonstrating that the proposed device is substantially equivalent to a legally marketed device. If the FDA

agrees that the proposed device is substantially equivalent to the predicate device, then 510(k) clearance to market will be granted.

After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would

constitute a major change in its intended use, requires a new 510(k) clearance or could require a pre-market approval.

Clinical trials are almost always required to

support a pre-market approval application and are sometimes required for a 510(k) pre-market notification. These trials generally require

submission of an application for an investigational device exemption. An investigational device exemption must be supported by pre-clinical

data, such as animal and laboratory testing results, which show that the device is safe to test in humans and that the study protocols

are scientifically sound. The FDA must approve an investigational device exemption, in advance, for a specified number of patients, unless

the product is deemed a non-significant risk device and is eligible for more abbreviated investigational device exemption requirements.

Both before and after a medical device is commercially

distributed, manufacturers and marketers of the device have ongoing responsibilities under FDA regulations. The FDA reviews design and

manufacturing practices, labeling and record keeping, and manufacturers’ required reports of adverse experiences and other information

to identify potential problems with marketed medical devices. Device manufacturers are subject to periodic and unannounced inspection

by the FDA for compliance with the Quality System Regulation, which sets forth the Current Good Manufacturing Practice requirements that

govern the methods used in, and the facilities and controls used for the design, manufacture, packaging, servicing, labeling, storage,

installation and distribution of all finished medical devices intended for human use.

On November 30, 2023, the FDA issued a proposed

rule to classify certain wound dressings and liquid wound washes containing antimicrobials with a low level of antimicrobial resistance

concern, including hypochlorous acid, into Class II medical devices. If finalized as proposed, we would be required to submit new 510(k)

applications for our products and to demonstrate compliance with special controls that require specific information relating to performance

testing and technical specifications, specific labeling requirements, and other requirements to mitigate the risks to health and demonstrate

a reasonable assurance of safety and effectiveness. Our existing devices could serve as predicates for the new devices. The FDA is proposing

that manufacturers will need to demonstrate compliance with applicable special controls within six months after the effective date of

the rule, when finalized.

FDA regulations prohibit the advertising and promotion

of a medical device for any use outside the scope of a 510(k) clearance or pre-market approval or for unsupported safety or effectiveness

claims. Although the FDA does not regulate physicians’ practice of medicine, the FDA does regulate manufacturer communications with

respect to off-label use.

If the FDA finds that a manufacturer has failed

to comply with FDA laws and regulations or that a medical device is ineffective or poses an unreasonable health risk, it can institute

or seek a wide variety of enforcement actions and remedies, ranging from a public warning letter to more severe actions such as:

· imposing fines, injunctions and civil penalties

· requiring a recall or seizure of products

· refusing requests for 510(k) clearance or pre-market approval of new products

· withdrawing 510(k) clearance or pre-market approvals already granted

· criminal prosecution

The FDA also has the authority to require a company

to repair, replace, or refund the cost of any medical device.

The FDA also administers certain controls over

the export of medical devices from the United States, as international sales of medical devices that have not received FDA clearance are

subject to FDA export requirements. Additionally, each foreign country subjects such medical devices to its own regulatory requirements.

In the European Union, there is a single regulatory approval process and approval is represented by the presence of a CE marking.

Other Regulation in the United States

The Physician Payments Sunshine Act

The Physician Payments Sunshine Act signed into

law in 2010 as part of the Affordable Care Act requires manufacturers of medical devices, drugs, biologicals, and medical supplies to

track and report certain payments made to and transfers of value provided to physicians and teaching hospitals as well as to report certain

ownership and investment interests held by physicians and their immediate family members. These manufacturers must report annually to

the Center for Medicare & Medicaid Services any direct or indirect payments and transfers of value of $10 or more, or annual aggregate

of $100 or more, made to physicians or to a third party at the request of or on behalf of a physician, including dentists. Payment includes:

consulting fees, compensation for services other than consulting, honoraria, gifts, entertainment, food, travel (including the specified

destinations), education, research, charitable contribution, royalty or license, current or prospective ownership or investment interest,

direct compensation for serving as faculty or as a speaker for a medical education program, grants, any other nature of the payment, or

other transfer of value. Manufacturers face monetary penalties for non-compliance. Certain payments related to research must be reported

separately. Product samples intended for patient use need not be reported.

Health Care Coverage and Reimbursement by Third-Party

Payors

Commercial success in marketing and selling products

depends, in part, on the availability of adequate coverage and reimbursement from third-party health care payors, such as government and

private health insurers and managed care organizations. Third-party payors are increasingly challenging the pricing of medical products

and services. Government and private sector initiatives to limit the growth of health care costs, including price regulation, competitive

pricing, and managed-care arrangements, are continuing in many countries where we do business, including the United States. These changes

are causing the marketplace to be more cost-conscious and focused on the delivery of more cost-effective medical products. Government

programs, including Medicare and Medicaid, private health care insurance companies, and managed-care plans control costs by limiting coverage

and the amount of reimbursement for particular procedures or treatments. This has created an increasing level of price sensitivity among

customers for our products. Some third-party payors also require that a favorable coverage determination be made for new or innovative

medical devices or therapies before they will provide reimbursement of those medical devices or therapies. Even though a new medical product

may have been cleared or approved for commercial distribution, we may find limited demand for the product until adequate coverage and

reimbursement have been obtained from governmental and other third-party payors.

Fraud and Abuse Laws

In the United States, we are subject to various

federal and state laws pertaining to healthcare fraud and abuse, which, among other things, prohibit the offer or acceptance of remuneration

intended to induce or in exchange for the purchase of products or services reimbursed under a federal healthcare program and the submission

of false or fraudulent claims with the government. These laws include the federal Anti-Kickback Statute, the False Claims Act and comparable

state laws. These laws regulate the activities of entities involved in the healthcare industry, such as Sonoma, by limiting the kinds

of financial arrangements such entities may have with healthcare providers who use or recommend the use of medical products, including,

for example, sales and marketing programs, advisory boards and research and educational grants. In addition, in order to ensure that healthcare

entities comply with healthcare laws, the Office of Inspector General of the U.S. Department of Health and Human Services recommends

that healthcare entities institute effective compliance programs. To assist in the development of effective compliance programs, the Office

of Inspector General has issued model Compliance Program Guidance, materials for a variety of healthcare entities which, among other things,

identify practices to avoid that may implicate the federal Anti-Kickback Statute and other relevant laws and describes elements of an

effective compliance program. While compliance with the Compliance Program Guidance materials is voluntary, a California law requires

pharmaceutical and devices manufacturers to initiate compliance programs that incorporate the Compliance Program Guidance and the July

2002 Pharmaceuticals Research and Manufacturers of America Code on Interactions with Healthcare Professionals.

Due to the scope and breadth of the provisions

of some of these laws, it is possible that some of our practices might be challenged by the government under one or more of these laws

in the future. Violations of these laws, which are discussed more fully below, can lead to civil and criminal penalties, damages, imprisonment,

fines, exclusion from participation in Medicare, Medicaid and other federal health care programs, and the curtailment or restructuring

of operations. Any such violations could have a material adverse effect on our business, financial condition, results of operations or

cash flows.

Anti-Kickback Laws

Our operations are subject to federal and state

anti-kickback laws. The federal Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, receiving, offering or

providing remuneration directly or indirectly to induce either the referral of an individual for a good or service reimbursed under a

federal healthcare program, or the furnishing, recommending, or arranging of a good or service, for which payment may be made under a

federal healthcare program, such as Medicare or Medicaid. The definition of “remuneration” has been broadly interpreted to

include anything of value, including such items as gifts, discounts, the furnishing of supplies or equipment, waiver of co-payments, and

providing anything at less than its fair market value. Because the Anti-Kickback Statute makes illegal a wide variety of common, even

beneficial, business arrangements, the Office of Inspector General was tasked with issuing regulations, commonly known as “safe

harbors,” that describe arrangements where the risk of illegal remuneration is minimal. As long as all of the requirements of a

particular safe harbor are strictly met, the entity engaging in that activity will not be prosecuted under the federal Anti-Kickback Statute.

The failure of a transaction or arrangement to fit precisely within one or more safe harbors does not necessarily mean that it is illegal

or that prosecution will be pursued. However, business arrangements that do not fully satisfy an applicable safe harbor may result in

increased scrutiny by government enforcement authorities, such as the Office of Inspector General. Our agreements to pay compensation

to our advisory board members and physicians who provide other services for us may be subject to challenge to the extent they do not fall

within relevant safe harbors under state and federal anti-kickback laws. In addition, many states have adopted laws similar to the federal

Anti-Kickback Statute, which apply to the referral of patients for health care services reimbursed by Medicaid, and some have adopted

such laws with respect to private insurance. Violations of the Anti-Kickback Statute are subject to significant fines and penalties and

may lead to a company being excluded from participating in federal health care programs.

False Claims Laws

The federal False Claims Act prohibits knowingly

filing a false claim, knowingly causing the filing of a false claim, or knowingly using false statements to obtain payment from the federal

government. Certain violations of the Anti-Kickback Statute constitute per se violations of the False Claims Act. Under the False Claims

Act, such suits are known as “qui tam” actions. Individuals may file suit on behalf of the government and share in any amounts

received by the government pursuant to a settlement. In addition, certain states have enacted laws modeled after the federal False Claims

Act under the Deficit Reduction Act of 2005, where the federal government created financial incentives for states to enact false claims

laws consistent with the federal False Claims Act. As more states enact such laws, we expect the number of qui tam lawsuits to increase.

Qui tam actions have increased significantly in recent years, causing greater numbers of healthcare companies to have to defend false

claims actions, pay fines or be excluded from Medicare, Medicaid or other federal or state government healthcare programs as a result

of investigations arising out of such actions.

HIPAA

Two federal crimes were created under the Health

Insurance Portability and Accountability Act of 1996, or HIPAA: healthcare fraud and false statements relating to healthcare matters.

The healthcare fraud statute prohibits knowingly and willfully executing a scheme to defraud any healthcare benefit program, including

private payors. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or

making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits,

items or services.

Health Information Privacy and Security

Individually identifiable health information is

subject to an array of federal and state regulation. Federal rules promulgated pursuant to HIPAA regulate the use and disclosure of health

information by “covered entities.” Covered entities include individual and institutional health care providers from which

we may receive individually identifiable health information. These regulations govern, among other things, the use and disclosure of health

information for research purposes, and require the covered entity to obtain the written authorization of the individual before using or

disclosing health information for research. Failure of the covered entity to obtain such authorization could subject the covered entity

to civil and criminal penalties. We may experience delays and complex negotiations in dealing with each entity’s differing interpretation

of the regulations and what is required for compliance. Also, where our customers or contractors are covered entities, including hospitals,

universities, physicians or clinics, we may be required by the HIPAA regulations to enter into “business associate” agreements

that subject the company to certain privacy and security requirements. In addition, many states have laws that apply to the use and disclosure

of health information, and these laws could also affect the manner in which we conduct research and other aspects of business. Such state

laws are not preempted by the federal privacy law when such laws afford greater privacy protection to the individual than the federal

law. While activities to assure compliance with health information privacy laws are a routine business practice, we are unable to predict

the extent to which resources may be diverted in the event of an investigation or enforcement action with respect to such laws.

Foreign Regulation

Whether or not we obtain FDA approval for a product,

approval of a product by the applicable regulatory authorities of foreign countries must be obtained before clinical trials or marketing
