Our Business

We make life better by delivering simple and sustainable solutions to big problems. We create and refine intellectual property that forms a foundation from which to build and create break-through products and technology for licensure to commercial partners. Our products harness the power of iodine – “Nature's Best Solution” – to eliminate contaminants that threaten our water, our health and our quality of life.

We invent, patent, prove and partner – to create best-of-class products and technology for commercialization as we build value for our shareholders and deliver benefits to our world.

Invent – Three Platform Technologies

We feature three patent protected platform technologies with diverse product opportunities across multiple industries – the AOS Filter, CupriDyne, and Isan. Each features the use of the all-natural iodine molecule. While they all use iodine, they are quite different in terms of the methods by which they exploit the use of iodine, the form and composition of iodine used, and therefore their function and value proposition can be quite different for each commercial application.

AOS Filter

The AOS Filter is our invention that combines iodine, water filter materials and electrolysis within a water filter device. Our filter generates extremely high oxidation potential in order to oxidize and break-down, or otherwise eliminate, soluble organic contaminants like acids, solvents, sulfurs, oil and gas by-products, and pharmaceutical by-products which are commonly found in all sorts of contaminated water. It also achieves extremely high rates of disinfection to eliminate infectious biological pathogens like salmonella, listeria and ecoli.

Extremely high oxidation potential is the key. The term ‘oxidation potential’ refers to the measure of the performance in which an oxidant is able to ‘break down’ a material through, in simple terms, the addition of oxygen and the transfer of electrons. Two commonly understood examples of oxidation are, as salt air rusts a shipyard anchor, or as fire is able to dismantle wood and turn it into ash. The key to our AOS Filter is its ability to generate extremely high oxidation potential in a continuous flow device that attacks contaminants in water that flow through the AOS Filter. The extremely high oxidation potential enables the AOS Filter to achieve performance results that researchers at the University of Alberta refer to as, ‘unprecendented’. Our AOS Filter embodies a break-through in science which led to BioLargo's co-founding of an ongoing research chair to solve the contaminated water issues associated with the Canadian Oil Sands at the University of Alberta Department of Engineering with the top five oil companies in Canada, the regional water district, and various environmental agencies of the Canadian government. Our work is continually expanding into a number of commercial applications with a key focus on food processing, agriculture and oil and gas. It is an award-winning invention that is supported with science and engineering financial support and grants from various federal and provincial agencies in Canada. The financial support is expanding along with the work to develop commercially available designs. We believe the AOS Filter has an important and substantial commercial opportunity in every segment of the water treatment industry.

CupriDyne®

Our CupriDyne formula is used to deliver iodine within products. It can be delivered in any physical form, and can be combined with other ingredients, like fragrances in our odor control products, and primitive surfactants in our stain and odor products. Additional ingredients can often be added without sacrificing its practical and safe antimicrobial functions. Our product designs include liquids, sprays, gels, powders, coatings and absorbents.

Safe and effective is the key. Each of our product designs delivers nature’s broadest spectrum and most potent disinfectant – iodine – safely and precisely to achieve effective broad-spectrum disinfection, unsurpassed odor and moisture control, and effective and gentle wound healing. Our primary ingredients, as well as reaction by-products, are “generally recognized as safe” (G.R.A.S) by the U.S. Food and Drug Administration as food additives in their basic forms. Its commercial product opportunities are diverse and we have an extensive menu of product designs in various stages of commercialization and licensure development, discussed in detail below in the “Commercial, Household and Personal Care Products” section. We specialize in delivering iodine, nature’s broadest spectrum and most potent disinfectant and essential nutrient, in safe, environmentally friendly, non-staining, non-toxic and effective product designs.

2

CupriDyne is unique. The iodine most of us are familiar with, sold in pharmacies and used by hospitals, has severe limitations – it is considered toxic, causes staining, and contains a limited dose of the active oxidizing ingredient. Our CupriDyne technology, on the other hand, directly addresses many of these shortcomings – it delivers iodine’s oxidizing ingredient (“free iodine”) with precision, ranging from very small doses up to very large doses with more than 20 times the power of traditional iodine. We can deliver iodine so that it is both non-toxic and non-staining, thus extending its usefulness well beyond historical product applications. Our formulations expand the functionality of our products well beyond simple disinfection.

Isan System

The Isan System is an automated iodine dosing system. It is the winner of a Top 50 Water Technology Award by the Artemis Project and a Dupont Innovation Award. Precise dosing combined with a straight-forward ‘set-it-and-forget-it’ automated computer controlled system is the key. The system features controlled measuring, flow control, dosing and iodine extraction/removal technology as well as an automatic tracking system that precisely delivers iodine in calibrated doses into a water steam or container of water. The Isan system has been proven to substantially reduce the incidence of fungal growth, spoilage, organisms and pathogens in water and on food. The system is able to operate at high flow rates.

First developed in Australia, the Isan system was initially registered with the APVMA (Australian Pesticides and Veterinary Medicines Authority) and FSANZ (Food Standards Australia and New Zealand) in Australia and New Zealand. The system has meaningful use and commercial value in any industry that can benefit from a precise use of iodine in water, like; agriculture, food production and processing, manufacturing, industrial water processes, irrigation supply.

Patent - an Expanding Intellectual Property Estate

During 2014 we were issued five patents. We have 13 patents issued and multiple pending. We believe these patents provide a foundation from which to continue building our patent portfolio and we have reasonable basis upon which to rely on our patent protections in the field of art in which we practice. We also rely on trade secrets and technical know-how to establish and maintain additional protection of our intellectual property. As our capital resources permit, we expect to expand our patent protection as we continue to refine our inventions as well as make new discoveries. See the detailed discussion below of our patent portfolio.

Prove - a Continual Process

We have invested time and money in a wide array of third party testing, side-by-side comparisons and third party verifications to support our most important technical claims. The basic attributes of iodine are well understood by science and industry. We have evidence and experience to substantiate the following bold claims:

o AOS Filter- when compared to the best of class competition we are

■ 100 times more effective

■ less than 1/20^th the cost

■ more than 10 times faster

o CupriDyne

Partner – a Smart Strategic Decision

We seek to develop commercial partnerships with other companies who will partner with us and pay us for a negotiated contractual right to use our intellectual property (patents, formulas, designs, claims, know-how, secrets), in order to expand their business for their own commercial purposes. In those instances, we seek a reasonable deposit, a minimum commitment to volume, some territorial rights, and a percentage of sales for a mutually agreeable term and territory. We believe this licensing model will prove successful and meaningful for our company.

We have chosen to focus on business opportunities that we believe have some combination of the following attributes: a compelling commercial advantage, our products out-perform competing products, market segments in which we have the talent and resources or opportunity to succeed in executing our business plans; and uses where we can identify a compelling cost savings or value offering to increase market share.

We choose to pursue a licensing strategy for its obvious and well-understood high margins, potential for explosive revenue potential and capital conserving features. While this business model can also be highly dependent upon macro-economic factors like the relative stability of the national and international economy as well as cyclical nature of business, politics and climate for innovation and competing technical advances, we believe this is the most appropriate strategy for our company. We have learned from difficult and real life experience. When our commercial licensing partners are under financial pressure from macro-economic and political circumstances, including reorganizations, recapitalization, or consolidation, they hold on to capital and are less likely to take any risk for new product offerings. Timing is critically important. Companies facing circumstances beyond their management’s control are less likely to embrace any risk of innovation. Therefore, our time delays have negatively impacted our company by causing us to invest more capital, do more work, and advance our technology with nominal cash flow to support our work. However, while these delays have occurred and they were difficult, we have been able to maintain our operations, advance our scientific assets, build on our proven claims, refine our designs and we have continued to build a portfolio of both products and technology that we believe will ultimately enjoy meaningful commercial success.

While we have waited out many of the uncertainties of the macro-economic marketplace, we have advanced our commercial purposes and made investments in various aspects of product design, marketing and distribution, but only at an early stage and small level. In those instances, we consider these efforts to be a prelude to an ultimate licensing strategy. This strategy has been slower than we prefer. However, it has created a substantial level of diversification and breadth of potential revenue streams that we believe can and will generate meaningful revenues as they find traction in the marketplace. As we improve our access to capital, strengthen our balance sheet and can begin to generate meaningful cash flow, we believe those commercial opportunities will generate revenue for years to come as our products find their way into the marketplace.

In many situations, our potential licensing partners would prefer that we advance products all the way through proof of claim, manufacturing, market acceptance, well-established distribution and commercial success. While this is obvious, can be intriguing, and the relative benefits that would accrue to our valuation are clear, the risks of failure are equally high and this strategy would require substantially more capital than we have been able to secure during what many believe has been one of the most economically uncertain times in modern history. Therefore, we have chosen to invest our time and resources where we find leverage to move forward, knowing that our technical claims are proven, they are patented and that each product design has a high probability of success to find a partner and generate meaningful returns on our invested capital as our targeted licensing partners seek to deploy capital assets and begin taking advantage of our offering for their own commercial advancements.

Although our technology has commercial applications within many industries, we are focusing our efforts in three areas: water treatment, the companion animal industry, as a segment of the commercial, household and personal care products (“CHAPP”), and “advanced wound care.”

Within these broad categories, we also narrow our product focus to exploit opportunities that we believe are of high-value to potential customers and that present commercially significant opportunities.

5

We have a number of examples of strategic alliance or partnering initiatives whereby we are advancing both our science, our patents, our proof of claims, or field trials and our commercial opportunities. There are a number of noteworthy examples:

The University of Alberta

We are engaged in a cooperative research relationship with the University of Alberta and its researchers in Edmonton, Canada. Our offices and our lab are located within the University of Alberta research center at Discovery Place. Our research team is led by Richard Smith, Ph.D., and our Chief Science Officer, Kenneth Reay Code. We recently added two additional Ph.D. researchers. We are also able to utilize the extensive resources of the University and its researchers on a contract for hire basis as needed. We work closely with the Department of Agricultural, Food and Nutritional Science at the University of Alberta and its Department of Engineering. We have been awarded a number of financial awards and grants to support our ongoing research and development as we refine the AOS Filter in preparation of commercial pilots and commercial designs. Generally the financial awards take on two common themes: first, science and engineering grants in which the University of Alberta is the primary recipient to support work on and around our technology; and second, grants to BioLargo Water, Inc. our Canadian Subsidiary to support ongoing science and engineering to advance our AOS Filter towards commercialization. In both cases, the financial awards support much of the research budget, but not all of the related costs. This cooperative research arrangement has three high value propositions for BioLargo: (i) a depth of resources and talent to accomplish highly skilled work, (ii) financial aid to support research and development costs, (iii) independent and credible validation of our technical claims.

Clarion Water

As announced on August 18, 2014, we entered into a manufacturing and distribution license agreement for its Isan® system with Clarion Water, a new operating division of InsulTech Manufacturing, LLC (www.insultech.com), the latter of which has over 20 years of commercial success around the globe representing hundreds of millions in sales of technical products to Fortune 100 companies.

Owned in equal parts by BioLargo, Inc. and Peter Holdings, Ltd., the Isan system leverages the power of iodine to provide the world’s most effective disinfection dosing systems. It has been referred to as one of the most important technical advancements in food safety in the past 20 years. It won a ‘top 50 water company award’ by the Artemis Project in 2010 and a DuPont Innovation Award for its excellence in science and innovation in 2004.

The Isan system delivers Iodine as a powerful, broad-spectrum biocide that is a logical replacement for chlorine in applications involving irrigation supply and post-harvest sanitation.  Through its automated and precise dosing system, the Isan system can help increase the quality and shelf life of fruits, vegetables, and other produce, is effective against a host of bacteria and fungi, and helps producers conform to increasingly stringent food safety regulations such as the Hazard Analysis and Critical Control Points (HACCP), which addresses food safety through the analysis and control of raw material hazards.

The Isan system has been validated through early stage commercialization and comprehensive testing conducted in Australia and New Zealand. Clarion intends to leverage this early work and focus initial commercialization efforts on the vast opportunities for the technology in improving plant quality and shelf life as well as explore additional opportunities for use in select industrial applications.

Tom Bercaw, President and Founder of Clarion Water has commented, “We are excited about the significant opportunities for the Isan technology around the world. We conducted extensive market research to validate the high global demand for water disinfection systems with the performance and features of the Isan system.  The system features a green, environmentally friendly design focused on solving many of the critical issues faced by agriculture, industry, municipalities and others with regard to safe, effective and responsible water treatment. In addition, the Isan system has been proven to enhance food safety and HACCP compliance, which has been an ever increasing concern in the US and abroad. We believe the Isan system is a good fit for our talents, experience and market presence.”

Per the terms of our license agreement, Clarion receives the exclusive global manufacturing and distribution rights to the Isan system and use of all historical data to support its commercial focus. Clarion will pay BioLargo a patent maintenance fee of $25,000 per year paid quarterly in arrears, and royalties on revenue equal to 10% paid quarterly in arrears. There are no minimum royalty payments for the first two years, but at year three (beginning July 1, 2016) the minimum royalties are $50,000 per quarter, at year four $75,000 per quarter, and at year five and onward $100,000 per quarter. The intellectual property subject to the license agreement includes all intellectual property related to the Isan System, including all patents, trademarks, proprietary knowledge, and other similar know-how or rights relating to or arising out of the Isan System or the patents related to the Isan System. The agreement contains other terms and conditions typically found in intellectual property license agreements.

BioLargo and Peter Holdings received a royalty advance of $100,000 upon execution of a letter of intent in February of 2014, which will be applied to royalties received during the first two years of the agreement. BioLargo retains certain marketing rights to help develop clients for Clarion.

In February of 2015, Clarion Water introduced the new and improved Isan System at the world's largest agricultural trade show, the World AG Expo, as part of its commercial launch into the U.S. market.

Since licensing the technology from BioLargo last August, Clarion has completed a comprehensive technical and engineering update to the Isan System, featuring a new automated touch screen user interface, enhanced security, enhanced control features for increased monitoring and sensing, and adding automated functionality providing users unmatched flexibility, reliability and control over this state-of-the-art disinfectant delivery system, and begun commercial trials.

Downeast Logistics

In late 2013, we entered into a cooperative selling and distribution agreement with Downeast Logistics, a certified “Service-Disabled Veteran-Owned Small Business” (SDVOSB), as our distribution partner to facilitate our first order to the US Government. Downeast has been instrumental in developing ongoing sales to the United States Military. We have six products with National Stocking Numbers, and we have recently secured a $150,000 “Indefinite Delivery Purchase Order” (IDPO) for its Specimen Transport Solidifier pouches by the U.S. Defense Logistics Agency (DLA). The purchase order allows the DLA to purchase the product at agreed-upon prices for the following 12 months. In exchange, the company is awarded the contract to be the exclusive supplier of the designated product under the IDPO. The DLA has the option to expand the maximum award up to $300,000 for the year.

Downeast Logistics has operated for more than thirteen years, and will continue to offer our products through multiple channels of the US Government. Its designation as a SDVOSB places Downeast Logistics within a group of highly sought after vendors to the US government. Odor-No-More has registered, and is in the process of registering, itself as well as its products with several procurement agencies of the US Government. 

Independent Sales Representatives

We have a number of independent representatives developing selling channels for our odor control products. We are in customer trials for our smoke-odor eliminating products. The response has been excellent and we have received the highest marks for performance that is superior to the competing products. We continue to support these selling efforts with samples, training, selling materials and competitive bulk pricing. While we cannot predict the timing or outcome of these efforts, we are confident in our products ability to outperform the competition.

Multinationals

We have entered into technical non-disclosure agreements with very large companies to evaluate our AOS Filter and discuss potential strategic alliances. The claims we have put forth are well received. The focus of discussions has moved from efficacy, which is accepted, to a business case discussion relative to capital and time to market and the potential return on investment. While these discussions are ongoing, we continue to advance our science and proven claims. We are highly encouraged that our AOS Filter has an important role in commerce.

7

Commercial, Household and Personal Care Products

CHAPP includes broad product categories and many opportunities for the application of our technology. It is defined by the ability to utilize similar, if not identical, consumption products in multiple market segments. Detergents, single use absorbents, wipes, products that provide odor or disinfection control, and stain removal all fall within this category. Packaging ranges from consumer sizes of a few ounces to bulk packaging for commercial or industrial use. We are currently marketing products in this category under four brands – Odor-No-More, Nature’s Best Solution, Deodorall, and NBS - direct to consumers, through retail stores, and most recently, to the U.S. Government. 

We are continuing our efforts to generate “private label” clients. We have fulfilled some small orders for various products that we produced under a third party’s private brand. We are meeting with new potential customers for private label opportunities. We also are in discussions with potential strategic alliance partners to provide large scale manufacturing and distribution should we secure orders for the private label business opportunities.

Additionally, we continue to seek relationships with established companies for potential technology licenses in which our technology would be incorporated into new products for existing brands, or established products. 

Our sales in the CHAPP product category to-date are nominal. Product development, sales, and marketing require significant financial resources that we currently do not have. As such, our progress in this area has been slower than we had hoped. We are actively marketing the technology for licensure to established companies in this industry segment, and are continuing to expand our proof of claims and product designs for various odor and moisture control applications.

Advanced Wound Care – Clyra Medical Technologies Subsidiary

In 2012 we formed a subsidiary Clyra Medical Technologies, Inc. (“Clyra”) to commercialize our technology in the medical products industry, with an initial focus on advanced wound care. Our advanced wound care products combine broad-spectrum antimicrobial capabilities with iodine’s natural and well-understood metabolic pathway to promote healing. We believe these benefits, along with reduced product costs as compared with other antimicrobials, give our products a competitive advantage in the marketplace.

Clyra is currently in the product development and testing phase for a wound gel and wound cleaner product, and, subject to sufficient financial resources, intends ultimately to apply for FDA 510(k) approval for these two products to be sold into the advanced wound care industry. This development work is primarily being conducted in conjunction with our research at the University of Alberta, and we believe is nearing completion. While no assurances can be made about the ultimate success any FDA applications once filed, given the forward looking nature of such events, Clyra has retained and engaged a team of experts in the area to guide it through the process. The product development process has been more time consuming than originally anticipated, and our limited financial resources have impacted our ability to complete the process. Given the timing of the FDA process, and the requirement for approval before product can be sold, we do not anticipate product sales until late 2015 or early 2016. In the interim, we will continue to seek licensing partners, secure additional and dedicated capital resources for Clyra, and refine our product roll out, marketing, and distribution plans. A U.S. patent was recently issued for these products under development.

Intellectual Property

We regard our intellectual property as critical to our ultimate success. Our goal is to obtain, maintain and enforce patent protection for our products and technologies in geographic areas of commercial interest, and to protect our trade secrets and proprietary information through laws and contractual arrangements.

Our Chief Science Officer, Mr. Kenneth R. Code, has been involved in the research and development of the BioLargo technology since 1997. He has participated in the Canadian Federal Scientific Research and Experimental Development program and he was instrumental in the discovery, preparation and filing of the first BioLargo technology patents. He has worked with manufacturers, distributors and suppliers in a wide variety of industries to gain a full appreciation of the potential applications and the methodologies applicable to our BioLargo technology for their manufacture and performance. He continues to research methods and applications to continue to expand the potential uses of our BioLargo technology as well as work to uncover new discoveries that may provide addition commercial applications to help solve real world problems in the field of disinfection.

In 2013 and 2014, we continued improving our technology and creating new uses of our technology through further research and development efforts. During that time, we filed two U.S. patent applications, each comprised of multiple individual claims, and received notice of allowance or were granted five patents by the USPTO. Our technology also includes know-how and trade secrets, which, together with our intellectual property, contribute to our expertise in product design, manufacturing, product claims, safety features and competitive positioning of products that feature our BioLargo technology.

During 2015 we plan to continue to advance our proof of claims, inventions and patent filings.

We incurred $742,247 in 2013 and $642,923 in 2014 in expense related to our research and development activities. Our research and development expenditures over the next 12 months could vary significantly and will depend upon our access to capital. Although we are actively pursuing such financing, no such commitment is yet in place. We would invest any such funds primarily on continued testing of our BioLargo technology in certain applications and the development of additional production methods for use of our BioLargo technology in certain applications.

Pending Patent Applications

U.S. Patent Application 12/220,484 (filed July 24, 2008), relating to the use of an article for application to a surface to provide antimicrobial and/or anti-odor activity. At least one of the reagents is coated with a water-soluble, water dispersible or water-penetrable covering that prevents ambient conditions of 50% relative humidity at 25ºC from causing more than 10% of the total reagents exposed to the ambient conditions from reacting in a twenty-four hour period.

In addition to these applications, we have filed patent applications in multiple foreign countries, including the European Union, pursuant to the PCT, and other provisional applications. Subject to adequate financing, we intend to continue to expand and enhance our suite of intellectual property through ongoing focus on product development, new intellectual property development and patent applications, and further third-party testing and validations for specific areas of focus for commercial exploitation. We currently anticipate that additional patent applications will be filed during the next 12 months with the USPTO and the PCT, although we are uncertain of the cost of such patent filings, which will depend upon the number of such applications prepared and filed. The expense associated with seeking patent rights in multiple foreign countries is expensive, and will require substantial ongoing capital resources. However we cannot give any assurance that adequate capital will be available. Without adequate capital resources, we will be forced to abandon patent applications and irrevocably lose rights to our technologies.

ITEM 1A. RISK FACTORS

The Company faces a number of significant risks associated with its current plan of operations. These include the following:

The effects of the recent global economic crisis has had an impact our business, operating results, and financial condition, and the rate of recovery is uncertain.

The recent global economic crisis has caused disruptions and extreme volatility in global financial markets and increased rates of default and bankruptcy, and has impacted levels of consumer spending. It has tightened the supply of investment capital. These macroeconomic developments and the unpredictable rate of recovery could continue to negatively affect our business, operating results, and financial condition in a number of ways.

Our limited operating history makes evaluation of our business difficult.

We have limited historical financial data upon which to base planned operating expenses or forecast accurately our future operating results. Further, our limited operating history will make it difficult for investors and securities analysts to evaluate our business and prospects. Our failure to address these risks and difficulties successfully could seriously harm us.

We have never generated any significant revenues, have a history of losses, and cannot assure you that we will ever become or remain profitable.

We have not yet generated any significant revenue from operations and, accordingly, we have incurred net losses every year since our inception. To date, we have dedicated most of our financial resources to research and development, general and administrative expenses and initial sales and marketing activities. We have funded the majority of our activities through the issuance of debt or equity securities. We anticipate net losses and negative cash flow to continue for the foreseeable future until such time as licensing or operating revenue is generated in sufficient amounts to offset operating losses. Our ability to achieve profitability is dependent upon our continuing research and development, product development, and sales and marketing efforts, and our ability to successfully license our technology. There can be no assurance that our revenues will be sufficient for us to become profitable or thereafter maintain profitability. We may also face unforeseen problems, difficulties, expenses or delays in implementing our business plan.

Our cash requirements are significant. The failure to raise additional capital will have a significant adverse effect on our financial condition and its operations.

Our cash requirements and expenses will continue to be significant. Our net cash used in continuing operations for the years ended December 31, 2013 and 2014 was $1,212,252 and $1,718,621, respectively. These negative cash flows are primarily related to operating losses and, to a lesser extent, fluctuations in working capital items. We continue to use cash in 2015 as it becomes available and we anticipate that we will require significant additional financing for working capital requirements for the foreseeable future to continue the development, marketing and licensure of our technology and products based on our technology. Although we have been successful in raising funds in the past, there can be no assurance that we will be able to successfully raise funds in the future, especially in light of current adverse conditions in the capital markets and the weak economy generally. The failure to raise additional capital will have a significant adverse effect on our financial condition, our operations, and our ability to market and sell our products. Our ability to continue as a going concern is dependent on our ability to raise capital.

12

From time to time, we issue stock, instead of cash, to pay some of our operating expenses. These issuances are dilutive to our existing stockholders.

We are party to agreements that provide for the payment of, or permit us to pay at our option, securities in consideration for services provided to us. All such issuances are dilutive to our stockholders because they increase the total number of shares of our common stock issued and outstanding, even though such arrangements assist us with managing our cash flow at a time of increasing operating expenses coupled with decreased and further decreasing liquidity.

Our stockholders face further potential dilution in any new financing.

Any additional equity that we raise would dilute the interest of the current stockholders and any persons who may become stockholders before such financing. Given the low price of our common stock, such dilution in any financing of a significant amount could be substantial.

Our stockholders face further potential adverse effects from the terms of any preferred stock which may be issued in the future.

In order to raise capital to meet expenses or to acquire a business, our Board of Directors may issue additional stock, including preferred stock. Any preferred stock which we may issue may have voting rights, liquidation preferences, redemption rights and other rights, preferences and privileges. The rights of the holders of our common stock will be subject to, and in many respect subordinate to, the rights of the holders of any such preferred stock. Furthermore, such preferred stock may have other rights, including economic rights, senior to our common stock that could have a material adverse effect on the value of our common stock. Preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, can also have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock, thereby delaying, deferring or preventing a change in control of the Company.

There are several specific business opportunities we are considering in further development of our business. None of these opportunities is yet the subject of a definitive agreement and most or all of these opportunities will require additional funding obligations on our part, for which funding is not currently in place.

In furtherance of our business plan, we are presently considering a number of opportunities to promote our business, to further develop and broaden, and to license, our technology with third parties. While discussions are underway with respect to such opportunities, there are no definitive agreements in place with respect to any of such opportunities at this time. There can be no assurance that any such opportunities being discussed will result in definitive agreements or, if definitive agreements are entered into, that they will be on terms that are favorable to us.

Moreover, should any of these opportunities result in definitive agreements being executed or consummated, we may be required to expend additional monies above and beyond our current operating budget to promote such endeavors. No such financing is in place at this time for such endeavors and we cannot assure you that any such financing will be available, or if it is available whether it will be on terms that are favorable to the company.

The cost of maintaining our public company reporting obligations is high.

We are obligated to maintain our periodic public filings and public reporting requirements, on a timely basis, under the Rules and Regulations of the SEC. In order to meet these obligations, we will need to continue to raise capital. If adequate funds are not available, we will be unable to comply with those requirements and could cease to be qualified to have our stock traded in the public market. As a public company, we incur significant legal, accounting and other expenses. In addition, the Sarbanes-Oxley Act of 2002, as well as related rules adopted by the SEC, has imposed substantial requirements on public companies, including certain corporate governance practices and requirements relating to internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act.

13

We expect to incur future losses and may not be able to achieve profitability.

Although we are generating limited revenue from the sale of our products, and we expect to generate revenue from new products we are introducing, and eventually from other license or supply agreements, we anticipate net losses and negative cash flow to continue for the foreseeable future until such time as our products are expanded in the marketplace and they gain broader acceptance by resellers and customers. Our current level of sales is not sufficient to support the financial needs of our business. We cannot predict when sales volumes will be sufficiently large to cover our operating expenses. We intend to expand our marketing efforts of our products as financial resources are available, and we intend to continue to expand our research and development efforts. Consequently, we will need to generate significant additional revenue or seek additional financings to fund our operations. This has put a proportionate corresponding demand on capital. Our ability to achieve profitability is dependent upon our efforts to deliver a viable product and our ability to successfully bring it to market, which we are currently pursuing. Although our management is optimistic that we will succeed in licensing our technology, we cannot be certain as to timing or whether we will generate sufficient revenue to be able to operate profitably. If we cannot achieve or sustain profitability, we may not be able to fund our expected cash needs or continue our operations. If we are not able to devote adequate resources to promote commercialization of our technology, our business plans will suffer and may fail.

Because we have limited resources to devote to sales, marketing and licensing efforts with respect to our technology, any delay in such efforts may jeopardize future research and development of technologies, and commercialization of our technology. Although our management believes that it can finance commercialization efforts through sales of our securities and possibly other capital sources, if we do not successfully bring our technology to market, our ability to generate revenues will be adversely affected.

If we are not able to manage our anticipated growth effectively, we may not become profitable.

We anticipate that expansion will continue to be required to address potential market opportunities for our technology and our products. Our existing infrastructure is limited, is not scalable, and will not support future growth, if any. There can be no assurance that we will have the financial resources to create new infrastructure, or that any such infrastructure will be sufficiently scalable to manage future growth, if any. There also can be no assurance that if we invest in additional infrastructure, we will be effective in expanding our operations or that our systems, procedures or controls will be adequate to support such expansion. In addition, we will need to provide additional sales and support services to our partners if we achieve our anticipated growth with respect to the sale of our technology for various applications. Failure to properly manage an increase in customer demands could result in a material adverse effect on customer satisfaction, our ability to meet our contractual obligations, and on our operating results.

Some of the products incorporating our technology will require regulatory approval.

The products in which our technology may be incorporated have both regulated and non-regulated applications. The regulatory approvals for certain applications may be difficult, impossible, time consuming and or expensive to obtain. While our management believes such approvals can be obtained for the applications contemplated, until those approvals from the FDA or the EPA or other regulatory bodies, if required, at the federal and state levels, as may be required are obtained, then we may not be able to generate commercial revenues. Certain specific regulated applications and its use therein require highly technical analysis, additional third party validation and will require regulatory approvals from organizations like the FDA. Certain applications may also be subject to additional state and local agency regulations, increasing the cost and time associated with commercial strategies. Additionally, most products incorporating our technology that may be sold in the European Union (“EU”) will require EU and possibly also individual country regulatory approval. All such approvals, including additional testing, are time-consuming, expensive and do not have assured outcomes of ultimate regulatory approval.

14

We need to outsource and rely on third parties for the manufacture of the chemicals, material components or delivery apparatus used in our technology and part of our future success will be dependent on the timeliness and effectiveness of the efforts of these third parties.

We do not have the required financial and human resources or capability to manufacture the chemicals that comprise our technology. Our business model calls for the outsourcing of the manufacture of these chemicals in order to reduce our capital and infrastructure costs as a means of potentially improving our financial position and the profitability of our business. Accordingly, we must enter into agreements with other companies that can assist us and provide certain capabilities, including sourcing and manufacturing, which we do not possess. We may not be successful in entering into such alliances on favorable terms or at all. Even if we do succeed in securing such agreements, we may not be able to maintain them. Furthermore, any delay in entering into agreements could delay the development and commercialization of our technology or reduce its competitiveness even if they reach the market. Any such delay related to such future agreements could adversely affect our business.

If any party to which we have outsourced certain functions fails to perform its obligations under agreements with us, the commercialization of our technology could be delayed or curtailed.

To the extent that we rely on other companies to manufacture the chemicals used in our technology, or sell or market products incorporating our technology, we will be dependent on the timeliness and effectiveness of their efforts. If any of these parties does not perform its obligations in a timely and effective manner, the commercialization of our technology could be delayed or curtailed because we may not have sufficient financial resources or capabilities to continue such efforts on our own.

We rely on a small number of key supply ingredients in order to manufacture our products

All of the supply ingredients used to manufacture our products are readily available from multiple suppliers. However, commodity prices for these ingredients can vary significantly and the margins that we are able to generate could decline if prices rise. If our manufacturing costs rise significantly, we may be forced to raise the prices for our products, which may reduce their acceptance in the marketplace.

If our technology or products incorporating our technology do not gain market acceptance, it is unlikely that we will become profitable.

The potential markets for products into which our technology can be incorporated are rapidly evolving, and we have many successful competitors. At this time, our technology is unproven in its commercial use, and the use of our technology by others is nominal. The commercial success of products incorporating our technology will depend upon the adoption of our technology by commercial and consumer end users in various fields.

15

Market acceptance may depend on many factors, including:

• the willingness and ability of consumers and industry partners to adopt new technologies;

• our ability to convince potential industry partners and consumers that our BioLargo technology is an attractive alternative to other technologies for disinfection, sanitization, remediation, reduction of disease transfer and as a protective and safety device against biohazardous materials;

• our ability to obtain the chemicals from third parties that are used in our BioLargo technology, in sufficient quantities with acceptable quality and at an acceptable cost; and

• our ability to license our BioLargo technology in a commercially effective manner.

If products incorporating our technology do not achieve a significant level of market acceptance, demand for our technology itself may not develop as expected and, in such event, it is unlikely that we will become profitable.

Any revenues that we may earn in the future are unpredictable, and our operating results are likely to fluctuate from quarter to quarter.

We believe that our future operating results will fluctuate due to a variety of factors, including:

• delays in product development by us or third parties;

• market acceptance of products incorporating our BioLargo technology;

• changes in the demand for, and pricing, of products incorporating our BioLargo technology;

• competition and pricing pressure from competitive products;

• manufacturing delays; and

• expenses related to, and the results of, proceedings relating to our intellectual property.

We expect our operating expenses will continue to fluctuate significantly in 2015 and beyond, as we continue our research and development, and increase our marketing and licensing activities. Although we expect to generate revenues from licensing our technology in the future, revenues may decline or not grow as anticipated and our operating results could be substantially harmed for a particular fiscal period. Moreover, our operating results in some quarters may not meet the expectations of stock market analysts and investors. In that case, our stock price most likely would decline.

We have no product distribution experience and we expect to rely on third parties who may not successfully sell our products.

We have no product distribution experience and currently rely and plan to rely primarily on product distribution arrangements with third parties. We also plan to license our technology to certain third parties for commercialization of certain applications. We expect to enter into additional distribution agreements and licensing agreements in the future, and we may not be able to enter into these additional agreements on terms that are favorable to us, if at all. In addition, we may have limited or no control over the distribution activities of these third parties. These third parties could sell competing products and may devote insufficient sales efforts to our products. As a result, our future revenues from sales of our products, if any, will depend on the success of the efforts of these third parties.

16

We may not be able to attract or retain qualified senior personnel.

We believe we are currently able to manage our current business with our existing management team. However, as we expand the scope of our operations, we will need to obtain the full-time services of additional senior management and other personnel. Competition for highly-skilled personnel is intense, and there can be no assurance that we will be able to attract or retain qualified senior personnel. Our failure to do so could have an adverse effect on our ability to implement our business plan. As we add full-time senior personnel, our overhead expenses for salaries and related items will increase from current levels and, depending upon the number of personnel we hire and their compensation packages, these increases could be substantial.

If we lose our key personnel or are unable to attract and retain additional personnel, we may be unable to achieve profitability.

Our future success is substantially dependent on the efforts of our senior management, particularly Dennis P. Calvert, our president and chief executive officer, and Kenneth Reay Code, our chief science officer. The loss of the services of either of these officers or other members of our senior management may significantly delay or prevent the achievement of product development and other business objectives. Because of the scientific nature of our business, we depend substantially on our ability to attract and retain qualified marketing, scientific and technical personnel. There is intense competition among specialized and technologically-oriented companies for qualified personnel in the areas of our activities. If we lose the services of, or do not successfully recruit key marketing, scientific and technical personnel, the growth of our business could be substantially impaired. At present, we do not maintain key man insurance for any of our senior management, although management is evaluating the potential of securing this type of insurance in the future as may be available.

Nondisclosure agreements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information.

In order to protect our proprietary technology and processes, we rely in part on nondisclosure agreements with our employees, potential licensing partners, potential manufacturing partners, testing facilities, universities, consultants, agents and other organizations to which we disclose our proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover trade secrets and proprietary information, and in such cases we could not assert any trade secret rights against such parties. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position. Since we rely on trade secrets and nondisclosure agreements, in addition to patents, to protect some of our intellectual property, there is a risk that third parties may obtain and improperly utilize our proprietary information to our competitive disadvantage. We may not be able to detect unauthorized use or take appropriate and timely steps to enforce our intellectual property rights.

We have been may become subject to product liability claims.

As a business which manufactures and markets products for use by consumers and institutions, we may become liable for any damage caused by our products, whether used in the manner intended or not. Any such claim of liability, whether meritorious or not, could be time-consuming and/or result in costly litigation. Although we maintain general liability insurance, our insurance may not cover potential claims of the types described above and may not be adequate to indemnify for all liabilities that may be imposed. Any imposition of liability that is not covered by insurance or is in excess of insurance coverage could harm our business and operating results, and you may lose some or all of any investment you have made, or may make, in our company.

17

Litigation or the actions of regulatory authorities may harm our business or otherwise distract our management.

Substantial, complex or extended litigation could cause us to incur major expenditures and distract our management. For example, lawsuits by employees, former employees, shareholders, partners, customers, or others, or actions taken by regulatory authorities, could be very costly and substantially disrupt our business.  Such lawsuits or actions could from time to time be filed against the Company and/or or our executive officers and directors.  Such lawsuits and actions are not uncommon, and we cannot assure you that we will always be able to resolve such disputes or actions on terms favorable to the Company.

If we suffer negative publicity concerning the safety or efficacy of our products, our sales may be harmed

If concerns should arise about the safety or efficacy of any of our products that are marketed, regardless of whether or not such concerns have a basis in generally accepted science or peer-reviewed scientific research, such concerns could adversely affect the market for those products. Similarly, negative publicity could result in an increased number of product liability claims, whether or not those claims are supported by applicable law.

The licensing of our technology or the manufacture, use or sale of products incorporating our technology may infringe on the patent rights of others, and we may be forced to litigate if an intellectual property dispute arises.

If we infringe or are alleged to have infringed another party’s patent rights, we may be required to seek a license, defend an infringement action or challenge the validity of the patents in court. Patent litigation is costly and time consuming. We may not have sufficient resources to bring these actions to a successful conclusion. In addition, if we do not obtain a license, do not successfully defend an infringement action or are unable to have infringed patents declared invalid, we may:

 •       incur substantial monetary damages;

 •       encounter significant delays in marketing our current and proposed product candidates;

 •       be unable to conduct or participate in the manufacture, use or sale of product candidates or methods of treatment requiring licenses;

 •       lose patent protection for our inventions and products; or

 •       find our patents are unenforceable, invalid, or have a reduced scope of protection.

Parties making such claims may be able to obtain injunctive relief that could effectively block the company’s ability to further develop or commercialize our current and proposed product candidates in the United States and abroad and could result in the award of substantial damages. Defense of any lawsuit or failure to obtain any such license could substantially harm the company. Litigation, regardless of outcome, could result in substantial cost to, and a diversion of efforts by, the Company.

Our patents are expensive to maintain, our patent applications are expensive to prosecute, and thus we are unable to file for patent protection in many countries.

Our ability to compete effectively will depend in part on our ability to develop and maintain proprietary aspects of our technology and either to operate without infringing the proprietary rights of others or to obtain rights to technology owned by third parties. Pending patent applications relating to our technology may not result in the issuance of any patents or any issued patents that will offer protection against competitors with similar technology. We must employ patent attorneys to prosecute our patent applications both in the United States and internationally. International patent protection requires the retention of patent counsel in multiple foreign countries and the payment of patent application fees in multiple foreign countries on or before filing deadlines set forth by the International Patent Cooperation Treaty (“PCT”). We therefore choose to file patent applications only in foreign countries where we believe the commercial opportunities require it, considering our available financial resources and the needs for our technology. This has resulted, and will continue to result, in the irrevocable loss of patent rights in all but a few foreign jurisdictions.

18

Patents we receive may be challenged, invalidated or circumvented in the future or the rights created by those patents may not provide a competitive advantage. We also rely on trade secrets, technical know-how and continuing invention to develop and maintain our competitive position. Others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets.

We are subject to risks related to future business outside of the United States.

Over time, we may develop business relationships outside of North America, and as those efforts are pursued, we will face risks related to those relationships such as:

• foreign currency fluctuations;

• unstable political, economic, financial and market conditions;

• import and export license requirements;

• trade restrictions;

• increases in tariffs and taxes;

• high levels of inflation;

• restrictions on repatriating foreign profits back to the United States;

• greater difficulty collecting accounts receivable and longer payment cycles;

• less favorable intellectual property laws;

• Regulatory requirements;

• unfamiliarity with foreign laws and regulations; and

• changes in labor conditions and difficulties in staffing and managing international operations.

The volatility of certain raw material costs may adversely affect operations and competitive price advantages for products that incorporate our technology.

Most of the chemicals and other key materials that we use in our business, such as minerals, fiber materials, and packaging materials, are neither generally scarce nor price sensitive, but prices for such chemicals and materials can be cyclical. Super Absorbent Polymer (SAP) beads, which are a petrochemical derivative, have been subject to periodic scarcity and price volatility from time to time during recent years, although prices are relatively stable at present. Should the volume of our sales increase dramatically, we may have difficulty obtaining SAP beads or other raw materials at a favorable price. Supply and demand factors, which are beyond our control, generally affect the price of our raw materials. We try to minimize the effect of price increases through production efficiency and the use of alternative suppliers. If we are unable to minimize the effects of increased raw material costs, our business, financial condition, results of operations and cash flows may be materially adversely affected.

Our common stock is thinly traded and largely illiquid.

Our stock is currently quoted on the OTC Markets (OTCQB). Being quoted on the OTCQB has made it more difficult to buy or sell our stock and from time to time has led to a significant decline in the frequency of trades and trading volume. Continued trading on the OTCQB will also likely adversely affect our ability to obtain financing in the future due to the decreased liquidity of the our shares and other restrictions that certain investors have for investing in OTCQB traded securities. While we intend to seek listing on the Nasdaq Stock Market (“Nasdaq”) or another stock exchange when the Company is eligible, there can be no assurance when or if our common stock will be listed on Nasdaq or another stock exchange.

19

The market price of our stock is subject to volatility.

Because our stock is thinly traded, its price can change dramatically over short periods, even in a single day. An investment in our stock is subject to such volatility and, consequently, is subject to significant risk. The market price of our common stock could fluctuate widely in response to many factors, including:

• developments with respect to patents or proprietary rights;

• announcements of technological innovations by us or our competitors;

• announcements of new products or new contracts by us or our competitors;

• actual or anticipated variations in our operating results due to the level of development expenses and other factors;

• changes in financial estimates by securities analysts and whether any future earnings of ours meet or exceed such estimates;

• conditions and trends in our industry;

• new accounting standards;

• general economic, political and market conditions and other factors; and

• the occurrence of any of the risks described in this Report.

You may have difficulty selling our shares because they are deemed “penny stocks”.

Because our common stock is not quoted on the Nasdaq National Market or Nasdaq Capital Market or listed on a national securities exchange, if the trading price of our common stock remains below $5.00 per share, which we expect for the foreseeable future, trading in our common stock will be subject to the requirements of certain rules promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which require additional disclosure by broker-dealers in connection with any trades involving a stock defined as a penny stock (generally, any non-Nasdaq equity security that has a market price of less than $5.00 per share, subject to certain exceptions). Such rules require the delivery, prior to any penny stock transaction, of a disclosure schedule explaining the penny stock market and the risks associated therewith and impose various sales practice requirements on broker-dealers who sell penny stocks to persons other than established customers and accredited investors (generally defined as an investor with a net worth in excess of $1,000,000 or annual income exceeding $200,000 individually or $300,000 together with a spouse). For these types of transactions, the broker-dealer must make a special suitability determination for the purchaser and have received the purchaser’s written consent to the transaction prior to the sale. The broker-dealer also must disclose the commissions payable to the broker-dealer, current bid and offer quotations for the penny stock and, if the broker-dealer is the sole market-maker, the broker-dealer must disclose this fact and the broker-dealer’s presumed control over the market. Such information must be provided to the customer orally or in writing before or with the written confirmation of trade sent to the customer. Monthly statements must be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stocks. The additional burdens imposed upon broker-dealers by such requirements could discourage broker-dealers from effecting transactions in our common stock, which could severely limit the market liquidity of the common stock and the ability of holders of the common stock to sell their shares.

Because our shares are deemed “penny stocks”, new rules make it more difficult to remove restrictive legends.

Rules put in place by the Financial Industry Regulatory Authority (FINRA) require broker-dealers to perform due diligence before depositing unrestricted common shares of penny stocks, and as such, some broker-dealers, including large national firms, are refusing to deposit unrestricted common shares of penny stocks. As such, it may be more difficult for purchases of shares in our private securities offerings to deposit the shares with broker-dealers and sell those shares on the open market.

The table below represents the quarterly high and low closing prices of our common stock for the last two fiscal years as reported by Yahoo Finance.

	2013				2014
	High		Low		High		Low
First Quarter	$	0.33	$	0.24	$	0.54	$	0.24
Second Quarter	$	0.39	$	0.25	$	1.09	$	0.36
Third Quarter	$	0.39	$	0.22	$	0.83	$	0.45
Fourth Quarter	$	0.27	$	0.15	$	0.53	$	0.31

The closing bid price for our common stock on March 30, 2015, was $0.[ ] per share. As of such date, there were approximately 660 registered owners of our common stock. We believe that the number of beneficial owners is substantially higher than this amount.

Dividends

We have never declared or paid a cash dividend to stockholders. We intend to retain any earnings which may be generated in the future to finance operations.

We have one equity compensation plan approved by our stockholders – the 2007 Equity Incentive Plan (the “2007 Plan”). The 2007 Plan was adopted by our Board of Directors on August 7, 2007 and approved by our stockholders at the 2007 Annual Meeting of Stockholders on September 6, 2007, and amended by our stockholders in 2011. Upon the adoption of the 2007 Plan, a prior plan approved in 2004 was frozen and no further grants will be made under that. It currently allows the issuance of a maximum aggregate 12,000,000 shares.

(2)

This includes various issuances to specific individuals either as a conversion of un-paid obligations or as part of their agreement for services. Each issuance is itself a plan and additional detail is available in Note [9] of our financial statements.

Sales of Unregistered Securities

The following is a report of the sales of unregistered securities not previously reported in a Quarterly Report on Form 10-Q or in a Current Report on

Form 8-K.

December Note Offering

In December 2014, we received $200,000 and issued convertible promissory notes with a maturity date in December 2015, which accrue interest at a rate of 12% per annum. Each noteholder, for no additional consideration, received a stock purchase warrant exercisable at $0.30 per share, which right terminates three years after the date of issuance. We issued warrants to purchase an aggregate 350,000 shares. Each noteholder may exchange the note for the securities offered in our current private securities offering.

Summer 2014 Private Securities Offering

Pursuant to a private offering of our common stock at a price of $0.40 per share (“Summer 2014 Offering”) that commenced on June 25, 2014 through

December 31, 2014, we sold 717,500 shares of our common stock to ten accredited investors, and received gross and net proceeds of $287,000 and $267,000, respectively. Fees related to this offering consisted of $20,000 cash payments and the issuance of 10,764 shares of our common stock at an exercise price of $0.40 per share.

Each purchaser of stock will receive, for no additional consideration, a stock purchase warrant which entitles the holder to purchase a number of additional shares of our common stock equal to the number of shares originally purchased. The warrant is exercisable at $0.75 per share, will expire on July 31, 2019, and is subject to a call provision in the event (i) the closing price of the Common Stock for each of twenty (20) consecutive business days, exceeds $1.50 per share (subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and the like after the date of issuance of this Warrant), (ii) the Restricted Stock is subject to resale pursuant to 17 C.F.R. 230.144 (“Rule 144”) or pursuant to any other exemption from registration under to the Securities Act of 1933, as amended and (iii) the Shares underlying the Warrant are registered with the SEC.

Payment of Vendor Fees

On December 26, 2014, we issued 21,721 shares of our common stock to a company providing ongoing services as payment for services totaling $10,725. The agreement required we issue common stock at a rate of $0.50 per share. The stock price on the grant date was $0.35 per share.

On October 31, 2014, we issued 18,750 shares of our common stock to a company providing ongoing services as payment for services totaling $7,500. The agreement required we issue common stock at a rate of $0.40 per share, the stock price on the grant date was $0.53 per share resulting in additional expense of $2,438.

Payment of Officer Salary and other obligations

On December 26, 2014, we issued and aggregate 327,444 shares of our common stock to our Chief Executive Officer, Chief Technology Officer and Vice President for accrued and unpaid obligations totaling $114,386. The common stock was issued at a rate of $0.35 per share; the stock price on the grant date was $0.35 per share.

All of these offerings and sales were made in reliance on the exemption from registration contained in Section 4(2) of the Securities Exchange Act and/or Regulation D promulgated thereunder as not involving a public offering of securities.

ITEM 6. SELECTED FINANCIAL DATA

Not applicable

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and the related notes to the consolidated financial statements included elsewhere in this report.

This discussion contains forward-looking statements that involve risks and uncertainties. Such statements, which include statements concerning future revenue sources and concentration, selling, general and administrative expenses, research and development expenses, capital resources, additional financings and additional losses, are subject to risks and uncertainties, including, but not limited to, those discussed above in Part I, Item 1 and elsewhere in this Annual Report, particularly in “Risk Factors,” that could cause actual results to differ materially from those projected. The forward-looking statements set forth in this Annual Report are as of December 31, 2014 unless expressly stated otherwise, and we undertake no duty to update this information.

Results of Operations—Comparison of the years ended December 31, 2014 and 2013

Revenue

We generated $111,547 in product revenues during the year ended December 31, 2014, compared with $67,946 during the year ended December 31, 2013. In addition, in the year ended December 31, 2013, we recorded $100,000 in license revenue from a customer deposit (related to a 2011 transaction with Central Garden & Pet). See Note 3 of our financial statements for additional information. Our 2014 product revenue consisted primarily of sales of our Odor-No-More branded products, primarily to the United States government (including the military). Our 2013 product revenue consisted primarily of sales of our Odor-No-More branded products and Deodorall branded products.

Cost of Goods Sold

Our cost of goods sold during 2014 was $55,999, or 50% of product revenues, as compared with $29,656 in 2013, or 44% of 2013 revenues. Our cost of goods sold includes costs of raw materials, contract manufacturing, and portions of salaries related to the product development and manufacturing. Because we have not achieved a large or consistent revenue base, the inclusion of the fixed costs related to the product development and manufacturing increases our cost of goods disproportionately, resulting in higher fluctuations. The difference in the percentage of product revenues in 2014 versus 2013 is due to such fluctuations.

24

Selling, General and Administrative Expense

Selling, General and Administrative expenses were $2,793,119 for the year ended December 31, 2014, compared to $2,004,777 for the year ended

December 31, 2013, an increase of $788,342. The increase is primarily related to the increase in fair value of stock option compensation in 2014 versus 2013, additional expense related to the establishment of a research center in Alberta, Canada and the retention of an investor relations firm in 2014. The largest components of the increase in selling, general and administrative expenses were:

a. Salaries and Payroll-related Expenses: These expenses were $675,415 for the year ended December 31, 2014, compared to $551,753 for the year ended December 31, 2013, an increase of $123,662. The increase is primarily attributable to fair value of the options issued to our Chief Financial Officer in 2014 compared to option issuances in 2013.

b. Consulting Expenses: These expenses were $632,830 for the year ended December 31, 2014, compared to $377,569 for the year ended December 31, 2013, an increase of $255,261. The increase is primarily attributable to fair value of the options issued in 2014 compared to option issuances in 2013.

c. Professional Fees: These expenses were $362,513 for the year ended December 31, 2014, compared to $373,322 for the year ended December 31, 2013, a decrease of $10,809. The use of and payment to professionals was consistent between 2014 and 2013.

d. Investor Relations: These expenses were $401,185 for the year ended December 31, 2014, compared to $15,793 for the year ended December 31, 2013, an increase of $385,392. The increase is due to the retention of an investor and public relations firm that began work in January 2014 as the Company has increased its public market profile.

Research and Development

Research and development expenses were $642,923 for the year ended December 31, 2014, compared to $742,247 for the year ended December 31, 2013, a decrease of $99,324. The decrease is due to a reduction in product development activities associated with the development of our advanced wound care products, offset by a continued development of our water treatment and oil and gas products.

Interest expense

Interest expense totaled $348,153 for the year ended December 31, 2014, compared to $281,591 for the year ended December 31, 2013, an increase of $66,562. The increase is primarily due to the conversion of notes payable into shares of our common stock in 2014.

Net Loss

Net loss for the year ended December 31, 2014 was $3,739,567, a loss of $0.05 per share, compared to a net loss for the year ended December 31, 2013 of $2,901,245, a loss of $0.04 per share. The increase in net loss per share for the year ended December 31, 2014 is primarily attributable to the increase in non-cash expenses recorded in Selling, General and Administrative expenses from the issuance of stock and stock options in exchange for services and accrued and unpaid payables and the retention of an investor relations firm, offset by the increase in number of shares outstanding.

Liquidity and Capital Resources

We have been, and anticipate that we will continue to be, limited in terms of our capital resources. Until we are successful in commercializing products or negotiating and securing payments for licensing rights from prospective licensing candidates, we expect to continue to have operating losses. Cash and cash equivalents totaled $154,460 at December 31, 2014. We had negative working capital of $422,347 as of December 31, 2014, compared with negative working capital of $605,961as of December 31, 2013. We had negative cash flow from operating activities of $1,718,621 for the year ended December 31, 2014, compared to a negative cash flow from operating activities of $1,212,252 for the year ended December 31, 2013. We used cash from financing activities to fund operations.  Our cash position is insufficient to meet our continuing anticipated expenses or fund anticipated operating expenses. Accordingly, we will be required to raise significant additional capital to sustain operations and further implement our business plan and we may be compelled to reduce or curtail certain activities to preserve cash. See Note 1 for a discussion of the presentation and preparation of the financial statements on a going concern basis.

25

Since we continue to be limited in terms of our capital resources, we are continuing to raise investment funds through private securities offerings. During the year ended December 31, 2014, we received gross proceeds of $1,810,644 from our financing activities. (See Note 5 and Note 11). We will be required to raise substantial additional capital to continue our current operations, as well as to meet our liabilities as they become due, if our efforts to commercialize our technology do not generate cash flow in the near future. There can be no assurance that we will be able to do so. If we are unable to do so, and our operations do not generate sufficient cash, we will be compelled to reduce or curtail certain activities to preserve cash, including without limitation, hiring additional personnel, additional scientific and third-party testing, costs associated with obtaining regulatory approvals and filing additional patent applications to protect our intellectual property. If we were forced to significantly curtail aspects of our operations, there would be a material adverse impact on our future outlook, as well as our current financial condition and results of operations.

It is also unlikely that we will be able to qualify for bank or other financial institutional debt financing until such time as our operations are considerably more advanced and we are able to demonstrate the financial strength to provide confidence for a lender.

Critical Accounting Policies

Our discussion and analysis of our results of operations and liquidity and capital resources are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, valuation of intangible assets and investments, and share-based payments. We base our estimates on anticipated results and trends and on various other assumptions that we believe are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results that differ from our estimates could have a significant adverse effect on our operating results and financial position. We believe that the following significant accounting policies and assumptions may involve a higher degree of judgment and complexity than others.

The methods, estimates and judgments the Company uses in applying these most critical accounting policies have a significant impact on the results of the Company reports in its financial statements.

Revenue Recognition

Revenues are recognized as risk and title to products transfers to the customer (which generally occurs at the time shipment is made), the sales price is fixed or determinable, and collectability is reasonably assured. We also may generate revenues from royalties and license fees from our intellectual property. Licensees typically pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. License fees are recognized over the estimated period of future benefit to the average licensee.

26

Valuation of Intangibles and Investments Acquired in a Non-Monetary Transaction

The Company has established a policy relative to the methodology to determine the value assigned to each intangible acquired with or licensed by the Company and/or services or products received for non-cash consideration of the Company’s common stock. The value is based on the market price of the Company’s common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received, as adjusted for applicable discounts.

Share-based Payments

It the Company’s policy to expense share-based payments as of the date of grant in accordance with Auditing Standards Codification Topic 718 “Share-Based Payment.” Application of this pronouncement requires significant judgment regarding the assumptions used in the selected option pricing model, including stock price volatility and employee exercise behavior. Most of these inputs are either highly dependent on the current economic environment at the date of grant or forward-looking expectations projected over the expected term of the award. As a result, the actual impact of adoption on future earnings could differ significantly from our current estimate.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We conducted an evaluation, under the supervision and with the participation of management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Annual Report.

Our procedures have been designed to ensure that the information relating to our company, including our consolidated subsidiaries, required to be disclosed in our SEC reports is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow for timely decisions regarding required disclosure. Based on this evaluation, our chief executive officer and chief financial officer concluded that as of the evaluation date our disclosure controls and procedures are effective.

It should be noted that the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

Under the supervision and with the participation of our management, including our Chief Executive Officer and the Chief Financial Officer, we have established internal control procedures in accordance with the guidelines established in the 2013 Framework —Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and through its evaluation of those internal control procedures, our management concluded that our internal controls over financial reporting are effective as of December 31, 2014.

This Annual Report does not include an attestation report of the Company’s independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to rules of the SEC that permit the company to provide only management’s report in this Annual Report.

Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls or our internal control over financial reporting, or any system we design or implement in the future, will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Changes in Internal Control

There have not been any changes in our internal control over financial reporting during the year ended December 31, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders

BioLargo, Inc.

We have audited the accompanying consolidated balance sheets of BioLargo, Inc. (the “Company”) as of December 31, 2013 and 2014, and the related consolidated statements of operations, stockholders’ equity (deficit), and cash flows for each of the years ended December 31, 2013 and 2014. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of BioLargo, Inc. as of December 31, 2013 and 2014, and the consolidated results of its operations and its cash flows for each of the years ended December 31, 2013 and 2014, in conformity with accounting principles generally accepted in the United States of America.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses, negative cash flows from operations and has limited capital resources, negative working capital, and a net stockholders’ deficit. These matters raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Business and Organization

Outlook

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of our business. As reflected in the accompanying financial statements for the year ended December 31, 2014, we had a net loss of $3,739,567, and, at December 31, 2014, we had negative working capital of $422,347, current assets of $230,591, an accumulated deficit of $79,019,719, and a net stockholders’ deficiency. The foregoing factors raise substantial doubt about our ability to continue as a going concern. Ultimately, our ability to continue as a going concern is dependent upon our ability to attract significant new sources of capital, attain a reasonable threshold of operating efficiencies and achieve profitable operations by licensing or otherwise commercializing products incorporating our BioLargo technology. The financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

We have been, and anticipate that we will continue to be, limited in terms of our capital resources. Our total cash and cash equivalents were $154,460 at December 31, 2014. We generated revenues of $111,547 in the year ended December 31, 2014, which amount was not sufficient to fund our operations. We generally have not had enough cash or sources of capital to pay our accounts payable and expenses as they arise, and have relied on the issuance of stock options and common stock, as well as extended payment terms with our vendors, to continue to operate. We will be required to raise substantial additional capital to expand our operations, including without limitation, hiring additional personnel, additional scientific and third-party testing, costs associated with obtaining regulatory approvals and filing additional patent applications to protect our intellectual property, and possible strategic acquisitions or alliances, as well as to meet our liabilities as they become due for the next 12 months.

As of December 31, 2014, we had $250,000 principal amount outstanding on our notes payable (see Note 5), and $494,938 of outstanding accounts payable. (See Note 10.)

During the year ended December 31, 2014, we received $1,335,644 net proceeds from our private securities offerings. (See Note 4.) We received $245,000 from the sale of stock in our subsidiary Clyra and we also received $200,000 net proceeds from convertible note obligations. (See Note 5.)

In the opinion of management, the accompanying balance sheets and related statements of operations, cash flows, and stockholders’ equity (deficit) include all adjustments, consisting only of normal recurring items, necessary for their fair presentation in conformity with accounting principles generally accepted in the United States of America.

Organization

We were initially organized under the laws of the State of Florida in 1989, and in 1991 merged into a Delaware corporation. We operate five subsidiaries: BioLargo Life Technologies, Inc., organized under the laws of the State of California in 2006, Odor-No-More, Inc., organized under the laws of the State of California in 2009, Clyra Medical Technologies, Inc., organized under the laws of the State of California in 2012, BioLargo Water, Inc., organized under the laws of the State of California in 2013 and BioLargo Water Canada, organized under the laws of Canada in 2014.

Business Overview 

We feature three patent protected platform technologies with diverse product opportunities across multiple industries – the AOS Filter, CupriDyne, and Isan. Each features the use of the all-natural iodine molecule. While they all use iodine, they are quite different in terms of the methods by which they exploit the use of iodine, the form and composition of iodine used, and therefore their function and value proposition can be quite different for each commercial application.

Note 2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated.

Cash and Cash Equivalents

We consider all highly liquid investments with original maturities of three months or less or money market funds from substantial financial institutions to be cash equivalents. We place substantially all of our cash and cash equivalents with one financial institution. As of December 31, 2014, our cash deposits were less than the Federal Deposit Insurance Corporation insurance limit of $250,000 per owner. From time to time during the year we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the institution, however, we do not anticipate non-performance.

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts was $3,818 at December 31, 2013 and December 31, 2014.

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. Inventories consisted of:

	December 31, 2013		December 31, 2014
Raw materials	$	26,080	$	18,816
Finished goods		3,750		6,698
	$	29,830	$	25,514

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Other Assets

Other Assets consists of payments made to purchase patents related to our efforts in commercializing the ISAN system.

For the years ended December 31, 2013 and 2014 we recorded amortization expense totaling $10,920.

Long-lived and definite lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the expected future undiscounted cash flows from the use of the asset and its eventual disposition is less than the carrying amount of the asset, then an impairment loss is recognized. The impairment loss is measured based on the fair value of the asset. Any resulting impairment is recorded as a reduction in the carrying value of the related asset in excess of fair value and a charge to operating results. For the years ended December 31, 2013 and 2014, management determined that there was no impairment of its long-lived assets.

Equipment

Equipment is carried at cost and depreciated using the straight-line method over the estimated useful lives of the assets which is three years to 7 years. As of December 31, 2013 and 2014, our equipment was fully depreciated.

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the years ended December 31, 2013 and 2014, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company’s net loss.

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, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, uncollectible accounts receivable, asset depreciation and amortization, and taxes, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-based Payments

All share-based payments to employees, including grants of employee stock options, are recognized in the consolidated financial statements based on their fair values.

For stock issued to consultants and other non-employees for services, we record the expense based on the fair market value of the securities as of the date of the stock issuance. The issuance of stock warrants or options to non-employees are valued at the time of issuance utilizing the Black Scholes calculation and the amount is charged to expense.

BIOLARGO, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

During the years ended December 31, 2013 and 2014 we recorded an aggregate $39,200 and $25,200 in selling, general and administrative expense related to options issued pursuant to the 2007 Plan.

During the years ended December 31, 2013 and 2014 we recorded an aggregate $892,309 and $846,588 in selling, general and administrative expense related to options issued outside of the 2007 Plan.

During the year ended December 31, 2014 we issued 664,411 shares of our common stock to our President, Chief Technology Officer and Secretary in lieu of accrued and unpaid compensation and unreimbursed expenses totaling $294,798.

During the year ended December 31, 2013 we issued 1,483,764 shares of our common stock to our President, Chief Technology Officer and Secretary in lieu of accrued and unpaid compensation and unreimbursed expenses totaling $419,224.

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

Revenue Recognition

Revenues are recognized as risk and title to products transfers to the customer (which generally occurs at the time shipment is made), the sales price is fixed or determinable, and collectability is reasonably assured. We also may generate revenues from royalties and license fees from our intellectual property. Licensees typically pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. License fees are recognized over the estimated period of future benefit to the average licensee.

Income Taxes

The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of asset and liabilities. Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred tax asset and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We account for uncertainties in income tax law under a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns as prescribed by generally accepted accounting principles (“GAAP”). Under GAAP, the tax effects of a position are recognized only if it is “more-likely-than-not” to be sustained by the taxing authority as of the reporting date. If the tax position is not considered “more-likely-than-not” to be sustained, then no benefits of the position are recognized.

Management believes the carrying amounts of the Company's financial instruments as of December 31, 2013 and 2014 approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, prepaid assets, accounts payable, convertible notes, and other assets and liabilities.

Recent Accounting Pronouncements

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-08 (ASU 2014-08), Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360). ASU 2014-08 amends the requirements for reporting discontinued operations and requires additional disclosures about discontinued operations. Under ASU 2014-08, only disposals representing a strategic shift in operations or that have a major effect on the Company’s operations and financial results should be presented as discontinued operations. ASU 2014-08 is effective for annual periods beginning after December 15, 2014. As the Company is engaged in research and development activities, the Company does not expect the adoption of this guidance to have any impact on the Company’s financial statement presentation or disclosures.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers. ASU 2014-09 will eliminate transaction- and industry-specific revenue recognition guidance under current U.S. GAAP and replace it with a principle based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize revenue based on the value of transferred goods or services as they occur in the contract. ASU 2014-09 also will require additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for reporting periods beginning after December 15, 2016, and early adoption is not permitted. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the impact the adoption of ASU 2014-09 on the Company’s financial statement presentation and disclosures.

In August 2014, the FASB issued Accounting Standards Update No. 2014-15 (ASU 2014-15), Presentation of Financial Statements – Going Concern (Subtopic 205-10).  ASU 2014-15 provides guidance as to management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related note disclosures.  In connection with preparing financial statements for each annual and interim reporting period, an entity’s management should evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued (or at the date that the financial statements are available to be issued when applicable). Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company is currently evaluating the impact the adoption of ASU 2014-15 on the Company’s financial statement presentation and disclosures.

Note 3. Customer Deposit

In 2012, we executed a joint venture agreement with Peter Holdings Ltd., the principal funding source of the development of the Isan System, whereby we jointly purchased the intellectual property associated with the Isan System, and agreed to share any royalties from the intellectual property on an equal 50/50 basis. In February 2014, we received a deposit of $100,000 from InsulTech Manufacturing, LLC, an Arizona limited liability company d/b/a Clarion Water (“Clarion Water”) towards a worldwide, exclusive license of the Isan System. On August 12, 2014, we entered into a license agreement with Clarion Water in which we granted an exclusive license to commercialize the Isan System. The license agreement provides that the $100,000 deposit is non-refundable, and is to be credited to future payments of royalties or sublicense fees due under the license agreement. The agreement further provides for a 10% royalty of licensee’s “net sales revenue”, and 40% of sublicensing fees. Licensee is required to make minimum payments beginning July 1, 2016, of $50,000 per quarter, and we are obligated to share any revenues under the agreement on an equal basis with Peter Holdings Pty. Ltd. The intellectual property subject to the license agreement includes all intellectual property related to the Isan System, including all patents, trademarks, proprietary knowledge, and other similar know-how or rights relating to or arising out of the Isan System or the patents related to the Isan System. The agreement contains other terms and conditions typically found in intellectual property license agreements.

On March 24, 2011, we entered into a contract in which Central Garden & Pet Company (“Central”) was granted the exclusive worldwide right and license to sell, market, offer for sale, distribute import, export, and otherwise exploit products that contain the BioLargo technologies in the “pet supplies industry” (which is defined in the agreement, and does not include products for equine or livestock). Pursuant to the Central contract, we received a $100,000 non-refundable deposit which would be credited against future orders, if any.  On February 11, 2013, we gave Central written notice of their failure to purchase the minimum required product from us to maintain exclusive rights to our technology in the “pet supplies industry” pursuant to the agreement. To maintain exclusive rights, within 60 days of our written notice Central must have either purchased the minimum amount of product or compensate us for lost profits as if they had done so. Central failed to purchase products from us prior to the expiration of the 60-day period, and failed to otherwise compensate us for lost profits. As such, as of April 12, 2013, Central lost its exclusive rights to our technology in the “pet supplies industry”, and we recorded as revenue the $100,000 deposit paid in 2011.

Note 5. Notes and Convertible Notes Payable

In December 2014, we received $200,000 and issued convertible promissory notes with a maturity date in December 2015, which accrue interest at a rate of 12% per annum.

We issued warrants to purchase an aggregate 350,000 shares. Each noteholder may exchange the note for the securities offered in our current private securities offering.

The fair value of the warrants and the intrinsic value of the beneficial conversion feature resulted in a $200,000 discount on the note payables, of which $8,000 was amortized as interest expense for the year ended December 31, 2014.

On November 19, 2013, we received $50,000 pursuant to a line of credit whereby we have pledged our inventory and accounts receivable as collateral. The maturity date of the line of credit is May 15, 2015, which accrues interest at a rate of 24%.

On December 28, 2012, the note holder agreed to extend the maturity date of the note by a period of one year to December 31, 2013.

Note 7. Warrants

We have certain warrants outstanding to purchase our common stock, at various prices, as described in the following table:

	Number of
	Shares			Price Range
Outstanding as of December 31, 2012		8,390,741		$0.125	-	1.00
Issued		3,503,328		$0.25	-	0.50
Exercised		—			--
Expired		(1,275,298	)	$0.50	-	1.00
Outstanding as of December 31, 2013		10,618,771		$0.125	-	1.00
Issued		5,185,001		$0.30	-	0.75
Exercised		(674,288	)	$0.30	-	0.50
Expired		(6,291,362	)	$0.50	-	1.00
Outstanding as of December 31, 2014		8,838,122		$0.125	-	1.00

To determine interest expense related to our outstanding warrants issued in conjunction with debt offerings, the fair value of each award grant is estimated on the date of grant using the Black-Scholes option-pricing model and the calculated value is amortized over the life of the warrant. The determination of expense of warrants issued for services or settlement also uses the option-pricing model. The principal assumptions we used in applying this model were as follows:

	2013			2014
Risk free interest rate	0.15 %	-	0.78%	0.09%	-	1.55%
Expected volatility	112%	-	262%	184%	-	349%
Expected dividend yield		--			--
Forfeiture rate		--			--
Expected life in years	1	-	3	1	-	5

The risk-free interest rate is based on U.S Treasury yields in effect at the time of grant. Expected volatilities are based on historical volatility of our common stock.

We recorded $247,412 and $8,000 of interest expense related to the amortization of the discount on convertible notes, for the extension of warrants set to expire, and for the fair value of warrants issued for services for the years ended December 31, 2013 and 2014, respectively.

We recognize compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model. The following methodology and assumptions were used to calculate share based compensation for each of the years ended December 31, 2013 and 2014:

	2013							2014
	Non Plan				2007 Plan			Non Plan				2007 Plan
Risk free interest rate	2.66	-	3.04	%		2.19	%	2.25	-	2.76	%		2.63	%
Expected volatility	928	-	951	%		928	%	837	-	935	%		927	%
Expected dividend yield		--				—			--				—
Forfeiture rate		--				—			--				—
Expected life in years		10				10			10				10

Expected price volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Expected volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility.

The risk-free interest rate used in the Black-Scholes calculation is based on the prevailing U.S Treasury yield as determined by the U.S. Federal Reserve. We have never paid any cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future. The expected life in years is presumed to be the mid-point between the vesting and the end of the contractual term.

Historically, we have not had significant forfeitures of unvested stock options granted to employees and Directors. A significant number of our stock option grants are fully vested at issuance or have short vesting provisions. Therefore, we have estimated the forfeiture rate of our outstanding stock options as zero.

Note 11. Provision for Income Taxes

Given our historical losses from operations, income taxes have been limited to the minimum franchise tax assessed by the State of California.

At December 31, 2014, we had federal and California tax net operating loss carry-forwards of approximately $42 million. Due to changes in our ownership through various common stock issuances during 2002 and 2007, the utilization of net operating loss carry-forwards may be subject to annual limitations and discounts under provisions of the Internal Revenue Code. Such limitations could result in the permanent loss of a significant portion of the net operating loss carry-forwards. Realization of our deferred tax assets, which relate to operating loss carry-forwards and timing differences, is dependent on future earnings. The timing and amount of future earnings are uncertain and therefore we have established a 100% valuation allowance.

At December 31, 2014, our U.S. Federal and California State income tax returns related to the years 2010-2013 remain open to examination by tax authorities. However, given our history of net operating losses, as discussed above, the statute of limitations could remain open to examine years prior to 2007 for the year(s) in which net operating losses were originally incurred if/when we reach profitability and begin to utilize our net operating losses to offset taxable income.

Note 12. Noncontrolling Interest

In May 2012, we formed a subsidiary for the purpose of marketing and selling medical products containing our technology, Clyra Medical Technology, Inc. (“Clyra”). Until December 17, 2012, this subsidiary was wholly-owned, with 7,500 shares issued to BioLargo, Inc. On December 17, 2012, Clyra signed executive employment agreements with three individuals, in which each was granted 500 shares of Clyra common stock, one-third of which vested immediately, and the remaining over time. The shares granted to the three executives are restricted from transfer until a sale of the company, whether by means of a sale of its stock or substantially all of its assets, or otherwise by agreement of Clyra, BioLargo and the executives.

The holdings of the executive officers and investors represent 20.7% of the issued and outstanding stock of the company.

For the year ended December 31, 2014, Clyra generated no revenues and Clyra’s operations resulted in a net loss of $182,093 on a consolidated basis.

Note 13. Subsequent Events

Management has evaluated subsequent events through the date of the filing of this Annual Report and management noted the following for disclosure.

Note Payables

In January 2015, we received $133,000 and issued convertible promissory notes with a maturity date in January 2016, which accrue interest at a rate of 12% per annum. Each noteholder, for no additional consideration, received a stock purchase warrant exercisable at $0.30 per share, which right terminates three years after the date of issuance. We issued warrants to purchase an aggregate 266,000 shares. Each noteholder may exchange the note for the securities offered in our current private securities offering.

2015 Unit Offering

On January 15, 2015, we commenced a private securities offering of “units”, each Unit consisting of a convertible promissory note and “Series A” stock purchase warrant. The price and availability of the Units are set forth in a “pricing supplement” issued from time-to-time, and priced up to a 30% discount to the market price of the Company’s common stock. The Offering is subject to an over-allotment of 20%, or an additional $1,000,000 in Units, for an aggregate total of $6,000,000, and shall be known as the Company’s 2015 “Unit Offering.” The Company has the right to register the common shares underlying the notes and warrants (“Shares”) with the Securities and Exchange Commission, and the obligation to register the Shares in the event gross proceeds of $3,000,000 are raised in the Offering.

Purchasers of the Units will receive a convertible promissory note bearing interest at the rate of 12% per annum on the amount invested. Any interest due will be paid quarterly in arrears in cash or shares of common stock. If paid by the issuance of common stock, interest is paid at a conversion price equal to the average closing price of the Company’s common stock over the 20 trading days prior to the interest payment due date. The principal amount of the note may be paid by the issuance of shares of common stock, or cash, upon maturity at the Company’s election. When paid in shares, the number of shares to be issued shall be calculated by dividing the principal amount invested by the Unit price, as it is established at the time of the original investment by the applicable Pricing Supplement. Notes may be converted at any time by the investor, at maturity by the Company, or by the Company prior to maturity, so long as all of the following conditions are met: (i) the Shares issued as payment are registered with the SEC, (ii) the Company’s common stock closes for ten consecutive trading days at or above three times the Unit price. Notes mature on June 1, 2018.

In addition to the convertible promissory note, each investor will receive a “Series A Warrant” allowing for the purchase of the number of common shares equal to the investment amount divided by the Unit price, (e.g., one warrant share for each share of common stock which the investor is eligible to receive through conversion of his original convertible note) and, the warrant will have an exercise price as set forth in the pricing supplement. Each Series A Warrant expires June 1, 2020. The Company may “call” the Series A Warrant, requiring the investor to exercise the warrant within 30 days or forever lose the rights to do so, only if the following conditions have been met: (i) the underlying Shares are registered with the SEC, and (ii) the Company’s common stock closes for 10 consecutive trading days at or above two times the exercise price.

As of March 30, 2015, we received $255,000 from seven investors pursuant to a Pricing Supplement at $0.25 per Unit. We issued Series A Warrants to purchase an aggregate 1,020,000 shares at an exercise price of $0.40 per share.

CLYRA MEDICAL TECHNOLOGIES, INC.

WARRANT TO PURCHASE COMMON STOCK

WARRANT NO. XXXX ISSUED: XXXX

THIS CERTIFIES THAT, for value received, XXXXX (the “Holder”), is entitled to subscribe for and purchase from CLYRA MEDICAL TECHNOLOGIES, INC., a corporation organized under the laws of the state of California (the “Company”), subject to Section 1(b) hereof, commencing at the time periods prescribed herein and ending at 5:00 p.m. California time on July 30, 2015, XXXX shares (the “Shares”) of common stock, par value, $0.00067, of the Company (the “Common Stock”). The exercise price for each Share subject to this Warrant (the “Warrant Price”) is equal to $1,833.33. The number of Shares and the Warrant Price are subject to adjustment from time to time as provided in Section 4 of this Warrant.

This Warrant is issued in connection with and as consideration for the initial Holder’s purchase of common stock in the Company’s private securities offering dated December 17, 2012.

1.             Method of Exercise; Payment; Issuance of New Warrant.

(a) The purchase right represented by this Warrant may be exercised by the Holder, in whole or in part, subject to the limitation set forth below, and from time to time, by (i) the surrender of this Warrant (with a notice of exercise in the form attached hereto as Exhibit A, duly executed) at the principal office of the Company and (ii) the payment to the Company, by check or wire transfer of funds to an account specified in writing by the Company, of an amount equal to the aggregate Warrant Price. The Shares so purchased, representing the aggregate number of shares specified in the executed Exhibit A, shall be delivered to the Holder within a reasonable time, not exceeding ten (10) business days, after this Warrant shall have been so exercised. Upon receipt by the Company of this Warrant at the office of the Company, in proper form for exercise and accompanied by the amount equal to the aggregate Warrant Price, the Holder shall be deemed to be the holder of record of the Shares issuable upon such exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing such Shares shall not then be actually delivered to the Holder.

(b) If this Warrant shall have been exercised only in part, the Company shall, at the time of delivery of such Shares, deliver to the Holder a new Warrant evidencing the right to purchase the remaining Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant, or, at the request of Holder, appropriate notation may be made on this Warrant which shall then be returned to Holder.

2.             Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all preemptive rights, taxes, liens and charges with respect to the issue thereof; provided, however, that the Company shall not be required to pay any transfer taxes with respect to the issue of shares in any name other than that of the registered holder hereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. The Company shall at all times take all such action and obtain all such permits or orders as may be necessary to enable the Company lawfully to issue such Common Stock as duly and validly issued, fully paid and nonassessable shares upon exercise in full of this Warrant.

- 1 -

3.             Fractional Shares. No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the Fair Market Value of such Shares.

4.             Adjustment. This Warrant shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a)     Adjustment for Stock Splits and Combinations. If the Company shall at any time or from time to time after the date hereof effect a subdivision of the outstanding Common Stock, the Warrant Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the date hereof combine the outstanding Common Stock, the Warrant Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

(b)     Adjustment for Certain Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Warrant Price shall be decreased as of the time of such issuance, by multiplying the Warrant Price by a fraction:

(x) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance; and

(y) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

(c)     Adjustment of Number of Shares. Upon each adjustment of the Warrant Price pursuant to either Section 4(a) or 4(b) of this Warrant, the number of shares of Common Stock purchasable upon exercise of this Warrant shall be adjusted to the number of shares of Common Stock, calculated to the nearest one hundredth of a share, obtained by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment upon the exercise of the Warrant by the Warrant Price in effect prior to such adjustment and dividing the product so obtained by the new Warrant Price.

(d)     Adjustment for Reclassification, Exchange and Substitution. If the Common Stock issuable upon the exercise of this Warrant are changed into the same or different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reorganization, merger, consolidation or sale of assets, provided for in Section 4© below), then and in any such event the Holder shall have the right thereafter to exercise this Warrant into the kind and amount of stock and other securities receivable upon such recapitalization, reclassification or other change, by holders of the number of shares of Common Stock for which this Warrant might have been exercised immediately prior to such recapitalization, reclassification or change.

(e)     Reorganization, Mergers, Consolidations or Sales of Assets. If at any time or from time to time there is a capital reorganization of the Common Stock (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reclassification or exchange of shares provided for in Section 4(d) above) or a merger or consolidation of the Company with or into another entity, or a sale of all or substantially all of the Company’s properties and assets to any other person or entity, then, as a part of such reorganization, merger, consolidation or sale, provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant the number of shares of stock or other securities, money or property of the Company, or of the successor entity resulting from such merger or consolidation or sale, to which a holder of Common Stock deliverable upon conversion would have been entitled on such capital reorganization, merger, consolidation, or sale. The Company shall not effect any reorganization, merger, consolidation or sale unless prior to the consummation thereof each entity or person (other than the Company) that may be required to deliver any cash, securities or other property upon the exercise of this Warrant shall assume, by written instrument delivered to the Holder, the obligation to deliver to the Holder such cash, securities or other property as in accordance with the foregoing provisions the Holder may be entitled to receive. The foregoing provisions of this Section 4© shall similarly apply to successive reorganizations, mergers, consolidations and sales.

(f)     No Impairment. The Company will not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of this Section and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the Holder against dilution or other impairment. Without limiting the generality of the foregoing, the Company will not issue any capital stock of any class which is preferred as to dividends or as to the distribution of assets upon the voluntary or involuntary dissolution, liquidation or winding up of the Company.

(g)     Notice of Adjustments.

5.             The Company’s Obligation to Make Payments.

(a)     Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution, whether payable in cash, securities or other property of the Company, with respect to any of its capital stock for which an adjustment is not made pursuant to Section 4 of this Warrant, then and in each such event, the Company shall concurrently make a cash payment to the Holder equal to the product of (i) the quotient obtained by dividing (x) the amount of cash plus the fair value of any property or securities distributed by (y) the number of shares of Common Stock outstanding on the record date for such dividend or distribution and (ii) the number of Shares on such record date.

(b)     Redemption of Capital Stock. In the event the Company at any time or from time to time after the date hereof shall repurchase or redeem any of its capital stock or any rights, including without limitation, options, warrants or other convertible or exchangeable securities, to acquire such capital stock, then and in each such event, the Company shall concurrently make a cash payment to the Holder equal to the product of (i) the quotient obtained by dividing (x) the aggregate amount of cash and the aggregate fair value of any property paid out by the Company in connection with any such repurchase or redemption by (y) the number of shares of Common Stock outstanding on a fully diluted basis immediately after such repurchase or redemption and (2) the number of Shares.

- 3 -

6.             Notice of Record Date. In the event:

(1) that the Company declares a dividend (or any other distribution) on any of its capital stock (including without limitation, its Common Stock);

(6) of any offer of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Warrant Price then in effect.

(A)         the record date of such dividend, distribution, repurchase, redemption, subdivision or combination, or, if a record is not to be taken, the date as to which the holders of Common Stock of record to be entitled to such dividend, distribution, repurchase, redemption, subdivision or combination are to be determined;

(B)         the date on which such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, dissolution or winding up; or

(C)         the date on which such offering of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Warrant Price is expected to become consummated.

BIOLARGO, INC.

WARRANT TO PURCHASE COMMON STOCK

WARRANT NO. XXXX ISSUED: XXXX

THIS CERTIFIES THAT, for value received, XXXX (the “Holder”), is entitled to subscribe for and purchase from BIOLARGO, INC., a corporation organized under the laws of the state of Delaware (the “Company”), subject to Section 1(b) hereof, commencing at the time periods prescribed herein and ending at 5:00 p.m. California time on July 30, 2015 (“Expiration Date”), XXXX shares (the “Shares”) of BioLargo, Inc. common stock, par value, $0.00067 (the “Common Stock”), for each common share of Clyra Medical Technologies, Inc. tendered to BioLargo, Inc. (the “Warrant Price”). The number of Shares and the Warrant Price are subject to adjustment from time to time as provided in Sections 4 and 5 of this Warrant.

This Warrant is issued in connection with and as consideration for the initial Holder’s investment of $XXXX (“Investment Amount”) in the Clyra Medical Technologies, Inc. private securities offering of dated February 1, 2014. In addition to this Warrant, the initial Holder received a warrant to purchase shares of Clyra common stock for $1,833.33 per share (the “Clyra Warrant”).

1.             Method of Exercise; Payment; Issuance of New Warrant.

(a) The purchase right represented by this Warrant may be exercised by the Holder, in whole or in part, subject to the limitation set forth below, and from time to time, by (i) the surrender of this Warrant (with a notice of exercise in the form attached hereto as Exhibit A, duly executed) at the principal office of the Company and (ii) the tender of the original stock certificate evidencing the Holder’s shares of Clyra Medical Technologies, Inc. (“Clyra”) common stock. The Shares so purchased, representing the aggregate number of shares specified in the executed Exhibit A, shall be delivered to the Holder within a reasonable time, not exceeding ten (10) business days, after this Warrant shall have been so exercised. Upon receipt by the Company of this Warrant at the office of the Company, in proper form for exercise and accompanied by the aggregate Warrant Price, the Holder shall be deemed to be the holder of record of the Shares issuable upon such exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing such Shares shall not then be actually delivered to the Holder.

(b) If this Warrant shall have been exercised only in part, the Company shall, at the time of delivery of such Shares, deliver to the Holder a new Warrant evidencing the right to purchase the remaining Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant, or, at the request of Holder, appropriate notation may be made on this Warrant which shall then be returned to Holder.

- 1 -

2.             Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all preemptive rights, taxes, liens and charges with respect to the issue thereof; provided, however, that the Company shall not be required to pay any transfer taxes with respect to the issue of shares in any name other than that of the registered holder hereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. The Company shall at all times take all such action and obtain all such permits or orders as may be necessary to enable the Company lawfully to issue such Common Stock as duly and validly issued, fully paid and nonassessable shares upon exercise in full of this Warrant.

3.             Fractional Shares. No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the Fair Market Value of such Shares.

4.             Adjustment. This Warrant shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a)     Adjustment for Stock Splits and Combinations. If the Company shall at any time or from time to time after the date hereof effect a subdivision of the outstanding Common Stock, the Warrant Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the date hereof combine the outstanding Common Stock, the Warrant Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

(b)     Adjustment of Number of Shares. Upon each adjustment of the Warrant Price pursuant to Section 4(a) of this Warrant, the number of shares of Common Stock purchasable upon exercise of this Warrant shall be adjusted to the number of shares of Common Stock, calculated to the nearest one hundredth of a share, obtained by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment upon the exercise of the Warrant by the Warrant Price in effect prior to such adjustment and dividing the product so obtained by the new Warrant Price.

(c)     Adjustment for Reclassification, Exchange and Substitution. If the Common Stock issuable upon the exercise of this Warrant are changed into the same or different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision or combination provided for in Section 4(a) above, or a reorganization, merger, consolidation or sale of assets, provided for in Section 4(d) below), then and in any such event the Holder shall have the right thereafter to exercise this Warrant into the kind and amount of stock and other securities receivable upon such recapitalization, reclassification or other change, by holders of the number of shares of Common Stock for which this Warrant might have been exercised immediately prior to such recapitalization, reclassification or change.

- 2 -

(d)     Reorganization, Mergers, Consolidations or Sales of Assets. If at any time or from time to time there is a capital reorganization of the Common Stock (other than a subdivision or combination provided for in Section 4(a) above, or a reclassification or exchange of shares provided for in Section 4(c) above) or a merger or consolidation of the Company with or into another entity, or a sale of all or substantially all of the Company’s properties and assets to any other person or entity, then, as a part of such reorganization, merger, consolidation or sale, provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant the number of shares of stock or other securities, money or property of the Company, or of the successor entity resulting from such merger or consolidation or sale, to which a holder of Common Stock deliverable upon conversion would have been entitled on such capital reorganization, merger, consolidation, or sale. The Company shall not effect any reorganization, merger, consolidation or sale unless prior to the consummation thereof each entity or person (other than the Company) that may be required to deliver any cash, securities or other property upon the exercise of this Warrant shall assume, by written instrument delivered to the Holder, the obligation to deliver to the Holder such cash, securities or other property as in accordance with the foregoing provisions the Holder may be entitled to receive. The foregoing provisions of this Section 4(d) shall similarly apply to successive reorganizations, mergers, consolidations and sales.

(e)     No Impairment. The Company will not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of this Section and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the Holder against dilution or other impairment. Without limiting the generality of the foregoing, the Company will not issue any capital stock of any class which is preferred as to dividends or as to the distribution of assets upon the voluntary or involuntary dissolution, liquidation or winding up of the Company.

(f)     Notice of Adjustments. Whenever this Warrant shall be adjusted pursuant to this Section 4, the Company shall make a certificate signed by an officer of the Company setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the new Warrant Price and the type or the number of Shares purchasable after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the Holder.

5.     Cash Call and Conditional Price Adjustment. At any time one year after the “issued” date of this Warrant, noted above, but prior to the Expiration Date of this Warrant, if the “BLGO Average Price” (the average closing price of BioLargo’s common stock on the prior twenty (20) business days) is less than 25 cents per share, the following provisions apply:

(a)     Option for BioLargo to purchase. BioLargo may deliver a written notice to the Holder advising of its intent to purchase some or all of Holder’s shares of Clyra common stock (a “Purchase Notice”). The purchase price of the Clyra shares shall be determined by adding fifteen percent (15%) to the sum of the (i) Investment Amount and (ii) the cash paid to Clyra pursuant to the Clyra Warrant. Upon receipt of the Purchase Notice, Holder shall deliver to BioLargo the original share certificate(s) representing the number of shares indicated in the Purchase Notice. Upon delivery of the Purchase Notice, the Holder’s right to exercise this Warrant expires. Payment of the purchase price shall be made within 10 business days of the delivery of the Purchase Notice.

(b)     Adjustment to Warrant Price. The Warrant Price shall be adjusted such that the number of Shares issued per one share of Clyra shall be calculated by dividing 1,000 by 70 percent of the BLGO Average Price. For example, should the BLGO Average Price be 20 cents per share, the formula would be 1000 / (.7 * .20) = 7,142.86, and one share of Clyra could be exchanged pursuant to the provisions of this Warrant for 7,142 shares of BioLargo common stock, rather than 4,000 shares as originally set forth herein.

- 3 -

6.             The Company’s Obligation to Make Payments.

(a)     Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution, whether payable in cash, securities or other property of the Company, with respect to any of its capital stock for which an adjustment is not made pursuant to Section 4 of this Warrant, then and in each such event, the Company shall concurrently make a cash payment to the Holder equal to the product of (i) the quotient obtained by dividing (x) the amount of cash plus the fair value of any property or securities distributed by (y) the number of shares of Common Stock outstanding on the record date for such dividend or distribution and (ii) the number of Shares on such record date.

(b)     Redemption of Capital Stock. In the event the Company at any time or from time to time after the date hereof shall repurchase or redeem any of its capital stock or any rights, including without limitation, options, warrants or other convertible or exchangeable securities, to acquire such capital stock, then and in each such event, the Company shall concurrently make a cash payment to the Holder equal to the product of (i) the quotient obtained by dividing (x) the aggregate amount of cash and the aggregate fair value of any property paid out by the Company in connection with any such repurchase or redemption by (y) the number of shares of Common Stock outstanding on a fully diluted basis immediately after such repurchase or redemption and (2) the number of Shares.

7.             Notice of Record Date. In the event:

(1) that the Company declares a dividend (or any other distribution) on any of its capital stock (including without limitation, its Common Stock);

(2) that the Company repurchases or redeems any of its capital stock (including without limitation, its Common Stock) or any rights to acquire such capital stock;

(3) that the Company subdivides or combines its outstanding shares of Common Stock;

(4) of any reclassification of the Common Stock, or of any consolidation, merger or share exchange of the Company into or with another entity, or of the sale of all or substantially all of the assets of the Company;

(5) of the involuntary or voluntary dissolution, liquidation or winding up of the Company; or

(6) of any offer of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Warrant Price then in effect.

then the Company shall notify the Holder at least 30 days prior to the date specified in (A), (B) or (C) below, in writing stating:

- 4 -

(A)         the record date of such dividend, distribution, repurchase, redemption, subdivision or combination, or, if a record is not to be taken, the date as to which the holders of Common Stock of record to be entitled to such dividend, distribution, repurchase, redemption, subdivision or combination are to be determined;

(B)         the date on which such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, dissolution or winding up; or

(C)         the date on which such offering of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Warrant Price is expected to become consummated.

8.             Compliance with Securities Act; Disposition of Warrant or Common Stock.

(a)     Compliance with Securities Act. The Holder, by acceptance hereof, agrees that this Warrant and the Shares to be issued upon exercise hereof are being acquired for investment and that such Holder will not offer, sell or otherwise dispose of this Warrant or any Common Stock to be issued upon exercise hereof except under circumstances which will not result in a violation of the Securities Act of 1933, as amended (the “Act”).

THIS WARRANT AND THE SECURITIES REPRESENTED BY THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES ACT OF ANY STATE AND MAY NOT BE SOLD OR TRANSFERRED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACTS COVERING THIS WARRANT AND THE SECURITIES REPRESENTED BY THIS WARRANT OR PURSUANT TO AN EXEMPTION FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACTS.

BIOLARGO, INC.

[FORM OF] WARRANT TO PURCHASE COMMON STOCK

WITH CALLABLE PROVISION

WARRANT NO. XXX ISSUED: XXXX

THIS CERTIFIES THAT, for value received,                   XXXX                 (the “Holder”), is entitled to subscribe for and purchase from BIOLARGO, INC., a corporation organized under the laws of the state of Delaware (the “Company”), subject to the provisions hereof, commencing at the time periods prescribed herein and ending at 5:00 p.m. California time on December 31, 2016, XXXXX shares (the “Shares”) of common stock, par value, $0.00067, of the Company (the “Common Stock”). The exercise price for each Share subject to this Warrant (the “Warrant Price”) is equal to $0.30. The number of Shares and the Warrant Price are subject to adjustment from time to time as provided in Section 5 of this Warrant.

This Warrant is issued in connection with and as consideration for the initial Holder’s purchase of common stock in the Company’s private securities offering dated July 18, 2013.

1.             Method of Exercise; Payment; Issuance of New Warrant.

(a) The purchase right represented by this Warrant may be exercised by the Holder, in whole or in part, subject to the limitation set forth below, and from time to time, by (i) the surrender of this Warrant (with a “notice of exercise” in the form attached hereto as Exhibit A, duly executed) at the principal office of the Company and (ii) the payment to the Company, by check or wire transfer of funds to an account specified in writing by the Company, of an amount equal to the aggregate Warrant Price. The Shares so purchased, representing the aggregate number of shares specified in the executed Exhibit A, shall be delivered to the Holder within a reasonable time, not exceeding ten (10) business days, after this Warrant shall have been so exercised. Upon receipt by the Company of this Warrant at the office of the Company, in proper form for exercise and accompanied by the amount equal to the aggregate Warrant Price, the Holder shall be deemed to be the holder of record of the Shares issuable upon such exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing such Shares shall not then be actually delivered to the Holder.

(b) If this Warrant shall have been exercised only in part, the Company shall, at the time of delivery of such Shares, deliver to the Holder a new Warrant evidencing the right to purchase the remaining Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant, or, at the request of Holder, appropriate notation may be made on this Warrant which shall then be returned to Holder.

- 1 -

2.             Callable Provision. If the closing price of the Common Stock for each of forty (40) consecutive business days (the “Measurement Period”), exceeds $0.60 per share (subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and the like after the date of issuance of this Warrant), then the Company may, within five (5) business days of the end of any such Measurement Period, call for cancellation of up to 100% of all or any portion of this Warrant for which a Notice of Exercise Form has not yet been delivered (such right, a “Call”).  To exercise this right, the Company must deliver to the registered Holder a written notice (a “Call Notice”), indicating therein the unexercised portion of this Warrant to which such notice applies. In the event a Notice of Exercise Form for any portion of this Warrant subject to such Call Notice shall not have been received by the Company within thirty (30) calendar days after the date of the Call Notice, then the Warrant shall be forfeited in its entirety without payment or consideration to the registered Holder and shall automatically terminate without any further action by either party.  

3.             Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all preemptive rights, taxes, liens and charges with respect to the issue thereof; provided, however, that the Company shall not be required to pay any transfer taxes with respect to the issue of shares in any name other than that of the registered holder hereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. The Company shall at all times take all such action and obtain all such permits or orders as may be necessary to enable the Company lawfully to issue such Common Stock as duly and validly issued, fully paid and nonassessable shares upon exercise in full of this Warrant.

4.             Fractional Shares. No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the Fair Market Value of such Shares.

5.             Adjustment. This Warrant shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a)     Adjustment for Stock Splits and Combinations. If the Company shall at any time or from time to time after the date hereof effect a subdivision of the outstanding Common Stock, the Warrant Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the date hereof combine the outstanding Common Stock, the Warrant Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

(b)     Adjustment for Certain Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Warrant Price shall be decreased as of the time of such issuance, by multiplying the Warrant Price by a fraction:

- 2 -

(x) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance; and

(y) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

(c)     Adjustment of Number of Shares. Upon each adjustment of the Warrant Price pursuant to either Section 4(a) or 4(b) of this Warrant, the number of shares of Common Stock purchasable upon exercise of this Warrant shall be adjusted to the number of shares of Common Stock, calculated to the nearest one hundredth of a share, obtained by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment upon the exercise of the Warrant by the Warrant Price in effect prior to such adjustment and dividing the product so obtained by the new Warrant Price.

(d)     Adjustment for Reclassification, Exchange and Substitution. If the Common Stock issuable upon the exercise of this Warrant are changed into the same or different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reorganization, merger, consolidation or sale of assets, provided for in Section 4(e) below), then and in any such event the Holder shall have the right thereafter to exercise this Warrant into the kind and amount of stock and other securities receivable upon such recapitalization, reclassification or other change, by holders of the number of shares of Common Stock for which this Warrant might have been exercised immediately prior to such recapitalization, reclassification or change.

(e)     Reorganization, Mergers, Consolidations or Sales of Assets. If at any time or from time to time there is a capital reorganization of the Common Stock (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reclassification or exchange of shares provided for in Section 4(d) above) or a merger or consolidation of the Company with or into another entity, or a sale of all or substantially all of the Company’s properties and assets to any other person or entity, then, as a part of such reorganization, merger, consolidation or sale, provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant the number of shares of stock or other securities, money or property of the Company, or of the successor entity resulting from such merger or consolidation or sale, to which a holder of Common Stock deliverable upon conversion would have been entitled on such capital reorganization, merger, consolidation, or sale. The Company shall not effect any reorganization, merger, consolidation or sale unless prior to the consummation thereof each entity or person (other than the Company) that may be required to deliver any cash, securities or other property upon the exercise of this Warrant shall assume, by written instrument delivered to the Holder, the obligation to deliver to the Holder such cash, securities or other property as in accordance with the foregoing provisions the Holder may be entitled to receive. The foregoing provisions of this Section 4(e) shall similarly apply to successive reorganizations, mergers, consolidations and sales.

(f)     No Impairment. The Company will not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of this Section and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the Holder against dilution or other impairment. Without limiting the generality of the foregoing, the Company will not issue any capital stock of any class which is preferred as to dividends or as to the distribution of assets upon the voluntary or involuntary dissolution, liquidation or winding up of the Company.

- 3 -

(g)     Notice of Adjustments. Whenever this Warrant shall be adjusted pursuant to this Section 4, the Company shall make a certificate signed by an officer of the Company setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the new Warrant Price and the type or the number of Shares purchasable after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the Holder.

6.             The Company’s Obligation to Make Payments.

(a)     Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution, whether payable in cash, securities or other property of the Company, with respect to any of its capital stock for which an adjustment is not made pursuant to Section 4 of this Warrant, then and in each such event, the Company shall concurrently make a cash payment to the Holder equal to the product of (i) the quotient obtained by dividing (x) the amount of cash plus the fair value of any property or securities distributed by (y) the number of shares of Common Stock outstanding on the record date for such dividend or distribution and (ii) the number of Shares on such record date.

(b)     Redemption of Capital Stock. In the event the Company at any time or from time to time after the date hereof shall repurchase or redeem any of its capital stock or any rights, including without limitation, options, warrants or other convertible or exchangeable securities, to acquire such capital stock, then and in each such event, the Company shall concurrently make a cash payment to the Holder equal to the product of (i) the quotient obtained by dividing (x) the aggregate amount of cash and the aggregate fair value of any property paid out by the Company in connection with any such repurchase or redemption by (y) the number of shares of Common Stock outstanding on a fully diluted basis immediately after such repurchase or redemption and (2) the number of Shares.

7.             Notice of Record Date. In the event:

(1) that the Company declares a dividend (or any other distribution) on any of its capital stock (including without limitation, its Common Stock);

(2) that the Company repurchases or redeems any of its capital stock (including without limitation, its Common Stock) or any rights to acquire such capital stock;

(3) that the Company subdivides or combines its outstanding shares of Common Stock;

(4) of any reclassification of the Common Stock, or of any consolidation, merger or share exchange of the Company into or with another entity, or of the sale of all or substantially all of the assets of the Company;

- 4 -

(5) of the involuntary or voluntary dissolution, liquidation or winding up of the Company; or

(6) of any offer of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Warrant Price then in effect.

then the Company shall notify the Holder at least 30 days prior to the date specified in (A), (B) or (C) below, in writing stating:

(A)         the record date of such dividend, distribution, repurchase, redemption, subdivision or combination, or, if a record is not to be taken, the date as to which the holders of Common Stock of record to be entitled to such dividend, distribution, repurchase, redemption, subdivision or combination are to be determined;

(B)         the date on which such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, dissolution or winding up; or

(C)         the date on which such offering of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Warrant Price is expected to become consummated.

8.             Compliance with Securities Act; Disposition of Warrant or Common Stock.

(a)     Compliance with Securities Act. The Holder, by acceptance hereof, agrees that this Warrant and the Shares to be issued upon exercise hereof are being acquired for investment and that such Holder will not offer, sell or otherwise dispose of this Warrant or any Common Stock to be issued upon exercise hereof except under circumstances which will not result in a violation of the Securities Act of 1933, as amended (the “Act”).

[FORM OF] WARRANT TO PURCHASE COMMON STOCK

WARRANT NO. XXX ISSUED: XXXX, 2013

THIS CERTIFIES THAT, for value received,                   XXXX                 (the “Holder”), is entitled to subscribe for and purchase from BIOLARGO, INC., a corporation organized under the laws of the state of Delaware (the “Company”), subject to Section 1(b) hereof, commencing at the time periods prescribed herein and ending at 5:00 p.m. California time on July 30, 2015, XXXX shares (the “Shares”) of common stock, par value, $0.00067, of the Company (the “Common Stock”). The exercise price for each Share subject to this Warrant (the “Warrant Price”) is equal to $0.55. The number of Shares and the Warrant Price are subject to adjustment from time to time as provided in Section 4 of this Warrant.

This Warrant is issued in connection with and as consideration for the initial Holder’s purchase of common stock in the Company’s private securities offering dated January 11, 2013.

1.             Method of Exercise; Payment; Issuance of New Warrant.

(a) The purchase right represented by this Warrant may be exercised by the Holder, in whole or in part, subject to the limitation set forth below, and from time to time, by (i) the surrender of this Warrant (with a notice of exercise in the form attached hereto as Exhibit A, duly executed) at the principal office of the Company and (ii) the payment to the Company, by check or wire transfer of funds to an account specified in writing by the Company, of an amount equal to the aggregate Warrant Price. The Shares so purchased, representing the aggregate number of shares specified in the executed Exhibit A, shall be delivered to the Holder within a reasonable time, not exceeding ten (10) business days, after this Warrant shall have been so exercised. Upon receipt by the Company of this Warrant at the office of the Company, in proper form for exercise and accompanied by the amount equal to the aggregate Warrant Price, the Holder shall be deemed to be the holder of record of the Shares issuable upon such exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing such Shares shall not then be actually delivered to the Holder.

(b) If this Warrant shall have been exercised only in part, the Company shall, at the time of delivery of such Shares, deliver to the Holder a new Warrant evidencing the right to purchase the remaining Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant, or, at the request of Holder, appropriate notation may be made on this Warrant which shall then be returned to Holder.

- 1 -

2.             Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all preemptive rights, taxes, liens and charges with respect to the issue thereof; provided, however, that the Company shall not be required to pay any transfer taxes with respect to the issue of shares in any name other than that of the registered holder hereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. The Company shall at all times take all such action and obtain all such permits or orders as may be necessary to enable the Company lawfully to issue such Common Stock as duly and validly issued, fully paid and nonassessable shares upon exercise in full of this Warrant.

3.             Fractional Shares. No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the Fair Market Value of such Shares.

4.             Adjustment. This Warrant shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a)     Adjustment for Stock Splits and Combinations. If the Company shall at any time or from time to time after the date hereof effect a subdivision of the outstanding Common Stock, the Warrant Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the date hereof combine the outstanding Common Stock, the Warrant Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

(b)     Adjustment for Certain Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Warrant Price shall be decreased as of the time of such issuance, by multiplying the Warrant Price by a fraction:

(x) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance; and

(y) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

(c)     Adjustment of Number of Shares. Upon each adjustment of the Warrant Price pursuant to either Section 4(a) or 4(b) of this Warrant, the number of shares of Common Stock purchasable upon exercise of this Warrant shall be adjusted to the number of shares of Common Stock, calculated to the nearest one hundredth of a share, obtained by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment upon the exercise of the Warrant by the Warrant Price in effect prior to such adjustment and dividing the product so obtained by the new Warrant Price.

- 2 -

(d)     Adjustment for Reclassification, Exchange and Substitution. If the Common Stock issuable upon the exercise of this Warrant are changed into the same or different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reorganization, merger, consolidation or sale of assets, provided for in Section 4(e) below), then and in any such event the Holder shall have the right thereafter to exercise this Warrant into the kind and amount of stock and other securities receivable upon such recapitalization, reclassification or other change, by holders of the number of shares of Common Stock for which this Warrant might have been exercised immediately prior to such recapitalization, reclassification or change.

(e)     Reorganization, Mergers, Consolidations or Sales of Assets. If at any time or from time to time there is a capital reorganization of the Common Stock (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reclassification or exchange of shares provided for in Section 4(d) above) or a merger or consolidation of the Company with or into another entity, or a sale of all or substantially all of the Company’s properties and assets to any other person or entity, then, as a part of such reorganization, merger, consolidation or sale, provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant the number of shares of stock or other securities, money or property of the Company, or of the successor entity resulting from such merger or consolidation or sale, to which a holder of Common Stock deliverable upon conversion would have been entitled on such capital reorganization, merger, consolidation, or sale. The Company shall not effect any reorganization, merger, consolidation or sale unless prior to the consummation thereof each entity or person (other than the Company) that may be required to deliver any cash, securities or other property upon the exercise of this Warrant shall assume, by written instrument delivered to the Holder, the obligation to deliver to the Holder such cash, securities or other property as in accordance with the foregoing provisions the Holder may be entitled to receive. The foregoing provisions of this Section 4(e) shall similarly apply to successive reorganizations, mergers, consolidations and sales.

(f)     No Impairment. The Company will not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of this Section and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the Holder against dilution or other impairment. Without limiting the generality of the foregoing, the Company will not issue any capital stock of any class which is preferred as to dividends or as to the distribution of assets upon the voluntary or involuntary dissolution, liquidation or winding up of the Company.

(g)     Notice of Adjustments. Whenever this Warrant shall be adjusted pursuant to this Section 4, the Company shall make a certificate signed by an officer of the Company setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the new Warrant Price and the type or the number of Shares purchasable after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the Holder.

STOCK OPTION AGREEMENT

This Non-Qualified Stock Option Agreement (this “Agreement”) is made and entered into as of _________ (the “Grant Date”) by and between BioLargo, Inc., a Delaware corporation (the “Company”), whose address is 3500 W. Garry Ave, Santa Ana, California 92704, and _________________, an individual (“Optionee”). Capitalized terms used herein without definition shall have the meanings given to them in Appendix “A” attached hereto and incorporated herein by this reference).

RECITALS

A. Optionee has provided valuable services to the Company for which the Company owes the Optionee money, and Optionee has agreed to accept this Option in payment of the outstanding amounts pursuant to the AP Conversion Agreement between the parties.

NOW, THEREFORE, in consideration of the mutual covenants, agreements, representations and warranties herein set forth and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows:

1. Grant of Stock Option. The Company hereby grants to Optionee a Non-Qualified Stock Option (the “Option”) to purchase, upon and subject to the terms and conditions of this Agreement, all or any part of ________ Thousand (______) shares of Stock at a per share exercise price of $0.______ (the “Per Share Exercise Price”).

2. Vesting. The Option shall vest in full immediately upon grant.

3. Manner of Exercise and Payment.

3.1     Optionee shall exercise the Option by giving (a) written notice of such exercise to the Company, specifying the number of shares of Stock with respect to which such Option is being exercised, together with (b) payment of the full purchase price for such shares, by wire transfer to a Company account designated by the Company or by unendorsed certified or cashier’s check, equal to the number of shares to be purchased multiplied by the Per Share Exercise Price.

3.2     Cashless Exercise. In lieu of exercising this Option by payment in cash or check, Optionee may elect to pay the Per Share Exercise Price by reducing the number of Shares issuable upon exercise of this Option in accordance with the following formula:

X =	Y(A-B)
	A

     Where:           X     =     the number of Shares to be issued to the Optionee.

Y     =     the number of Shares requested to be exercised under this Option.

A     =     the Fair Market Value of one (1) Share of Common Stock as of the date such Option is exercised.

B     =     the Per Share Exercise Price.

3.1. Effective Date of Exercise. The date upon which such written notice is given and payment of the full purchase price is received by the Company shall be the exercise date for the Option; in the event of a cashless exercise, the date upon which such written notice is given shall be the exercise date for the Option. From such exercise date, Optionee shall be entitled to the issuance of a stock certificate evidencing Optionee’s ownership of the shares of Stock acquired pursuant to such exercise (but subject to Section 8 hereof). Optionee shall not have any of the rights or privileges of a stockholder of the Company (including, without limitation, rights to distributions, voting rights, inspection rights, dissenter’s rights, rights to bring a derivative action, or other rights of a shareholder under applicable corporate law) in respect of any shares of Stock issuable upon exercise of such Option until and only to the extent such Option is exercised and certificates representing such shares shall have been issued and delivered.

1

3.2. No Fractional Shares. No installment of such Stock Option shall be exercisable except with respect to whole shares.

4. Termination.

4.1. In General. The Option granted under Section 1 hereof, to the extent unexercised, shall terminate at the close of business on the tenth (10th) anniversary of the Grant Date.

4.2. Change of Control. Notwithstanding the provisions Section 2 above, any portion of the Option which has not yet vested shall be immediately vested in the event of, and prior to, a Change of Control. If, in connection with the Change of Control, this Option is not assumed, or if a substitute Option is not issued, or if the assumed or substituted awards fail to contain similar terms and conditions as the Option prior to the Change of Control or fail to preserve, to the extent applicable, the benefit to be provided to the Optionee as of the date of the Change of Control, including but not limited to the right of the Optionee to receive shares upon exercise of the Option that are registered for sale to the public pursuant to an effective registration statement filed with the U.S. Securities and Exchange Commission, then each holder of an Option that is outstanding as of the date of the Change of Control shall have the right, exercisable by written notice to the Company (or its successor in the Change of Control transaction) within 30 days after the Change of Control (but not beyond the Option’s expiration date), to receive, in exchange for the surrender of the Option, an amount of cash equal to the excess of the greater of the Fair Market Value of the Shares determined on the Change of Control date or the Fair Market Value of the Shares on the date of surrender covered by the Option (to the extent vested and not yet exercised) that is so surrendered over the purchase or grant price of such Shares under the Award. If the Board (or the Committee) so determines prior to the Change of Control, any such Option that is not exercised or surrendered prior to the end of such 30-day period will be cancelled.

5. Non-Transferability. Neither Optionee nor any successor or assignee thereof shall have any power or right to transfer, assign, anticipate, hypothecate or otherwise encumber any part or all of the Option granted under Section 1 hereof, other than by will or by the laws of descent and distribution, and such Option shall be exercisable during Optionee’s lifetime only by Optionee; nor shall all or any part of such Option be subject to seizure by any creditor of any such person, by a proceeding at law or in equity, and no such benefit shall be transferable by operation of law in the event of the bankruptcy or insolvency of Optionee or any successor or assignee thereof. Any such attempted assignment or transfer shall be void and shall terminate this Agreement, and the Company shall thereupon have no further liability hereunder.

6. Compliance With Securities and Tax Laws. No shares of Stock shall be issued pursuant to the exercise of the Option except in compliance with all applicable federal and state securities and tax laws and regulations and in compliance with rules of stock exchanges on which the Stock may be listed. In furtherance of the foregoing and not in order to limit the generality of the foregoing in any way:

6.1. Representation. The Company, as a condition to the issuance of such shares, may require the person exercising Option to represent and warrant at the time of such exercise that any shares of Stock acquired upon exercise are being acquired only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required under any applicable law, regulation or rule of any governmental agency.

6.2. Notice of Sale. The person acquiring such shares shall give the Company notice of any sale or other disposition of any such shares not less than ten (10) days after such sale or other disposition.

6.3. Withholding. Optionee acknowledges and agrees that the Company, in order to fulfill its withholding obligations under any federal, state or local tax law upon exercise of the Stock Option, may (a) withhold such sums from other compensation due Optionee, (b) require Optionee to pay to the Company such amounts as a condition to the delivery of shares pursuant to such exercise, or (c) sell shares that would otherwise be delivered to Optionee upon exercise of the Option in order to raise cash in the necessary amount.

1.             Method of Exercise; Payment; Issuance of New Warrant.

(a) The purchase right represented by this Warrant may be exercised by the Holder, in whole or in part, subject to the limitation set forth below, and from time to time, by (i) the surrender of this Warrant (with a notice of exercise in the form attached hereto as Exhibit A, duly executed) at the principal office of the Company and (ii) the payment to the Company, by check or wire transfer of funds to an account specified in writing by the Company, of an amount equal to the aggregate Warrant Price. The Shares so purchased, representing the aggregate number of shares specified in the executed Exhibit A, shall be delivered to the Holder within a reasonable time, not exceeding ten (10) business days, after this Warrant shall have been so exercised. Upon receipt by the Company of this Warrant at the office of the Company, in proper form for exercise and accompanied by the amount equal to the aggregate Warrant Price, the Holder shall be deemed to be the holder of record of the Shares issuable upon such exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing such Shares shall not then be actually delivered to the Holder.

(b) If this Warrant shall have been exercised only in part, the Company shall, at the time of delivery of such Shares, deliver to the Holder a new Warrant evidencing the right to purchase the remaining Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant, or, at the request of Holder, appropriate notation may be made on this Warrant which shall then be returned to Holder.

2.             Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all preemptive rights, taxes, liens and charges with respect to the issue thereof; provided, however, that the Company shall not be required to pay any transfer taxes with respect to the issue of shares in any name other than that of the registered holder hereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. The Company shall at all times take all such action and obtain all such permits or orders as may be necessary to enable the Company lawfully to issue such Common Stock as duly and validly issued, fully paid and nonassessable shares upon exercise in full of this Warrant.

3.             Fractional Shares. No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the Fair Market Value of such Shares.

4.             Adjustment. This Warrant shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a)     Adjustment for Stock Splits and Combinations. If the Company shall at any time or from time to time after the date hereof effect a subdivision of the outstanding Common Stock, the Warrant Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the date hereof combine the outstanding Common Stock, the Warrant Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

(b)     Adjustment for Certain Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Warrant Price shall be decreased as of the time of such issuance, by multiplying the Warrant Price by a fraction:

(x) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance; and

(y) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

(c)     Adjustment of Number of Shares. Upon each adjustment of the Warrant Price pursuant to either Section 4(a) or 4(b) of this Warrant, the number of shares of Common Stock purchasable upon exercise of this Warrant shall be adjusted to the number of shares of Common Stock, calculated to the nearest one hundredth of a share, obtained by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment upon the exercise of the Warrant by the Warrant Price in effect prior to such adjustment and dividing the product so obtained by the new Warrant Price.

(d)     Adjustment for Reclassification, Exchange and Substitution. If the Common Stock issuable upon the exercise of this Warrant are changed into the same or different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reorganization, merger, consolidation or sale of assets, provided for in Section 4(e) below), then and in any such event the Holder shall have the right thereafter to exercise this Warrant into the kind and amount of stock and other securities receivable upon such recapitalization, reclassification or other change, by holders of the number of shares of Common Stock for which this Warrant might have been exercised immediately prior to such recapitalization, reclassification or change.

- 2 -

(e)     Reorganization, Mergers, Consolidations or Sales of Assets. If at any time or from time to time there is a capital reorganization of the Common Stock (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reclassification or exchange of shares provided for in Section 4(d) above) or a merger or consolidation of the Company with or into another entity, or a sale of all or substantially all of the Company’s properties and assets to any other person or entity, then, as a part of such reorganization, merger, consolidation or sale, provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant the number of shares of stock or other securities, money or property of the Company, or of the successor entity resulting from such merger or consolidation or sale, to which a holder of Common Stock deliverable upon conversion would have been entitled on such capital reorganization, merger, consolidation, or sale. The Company shall not effect any reorganization, merger, consolidation or sale unless prior to the consummation thereof each entity or person (other than the Company) that may be required to deliver any cash, securities or other property upon the exercise of this Warrant shall assume, by written instrument delivered to the Holder, the obligation to deliver to the Holder such cash, securities or other property as in accordance with the foregoing provisions the Holder may be entitled to receive. The foregoing provisions of this Section 4(e) shall similarly apply to successive reorganizations, mergers, consolidations and sales.

(f)     No Impairment. The Company will not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of this Section and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the Holder against dilution or other impairment. Without limiting the generality of the foregoing, the Company will not issue any capital stock of any class which is preferred as to dividends or as to the distribution of assets upon the voluntary or involuntary dissolution, liquidation or winding up of the Company.

(g)     Notice of Adjustments. Whenever this Warrant shall be adjusted pursuant to this Section 4, the Company shall make a certificate signed by an officer of the Company setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the new Warrant Price and the type or the number of Shares purchasable after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the Holder.

5.             The Company’s Obligation to Make Payments.

(a)     Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution, whether payable in cash, securities or other property of the Company, with respect to any of its capital stock for which an adjustment is not made pursuant to Section 4 of this Warrant, then and in each such event, the Company shall concurrently make a cash payment to the Holder equal to the product of (i) the quotient obtained by dividing (x) the amount of cash plus the fair value of any property or securities distributed by (y) the number of shares of Common Stock outstanding on the record date for such dividend or distribution and (ii) the number of Shares on such record date.

(b)     Redemption of Capital Stock. In the event the Company at any time or from time to time after the date hereof shall repurchase or redeem any of its capital stock or any rights, including without limitation, options, warrants or other convertible or exchangeable securities, to acquire such capital stock, then and in each such event, the Company shall concurrently make a cash payment to the Holder equal to the product of (i) the quotient obtained by dividing (x) the aggregate amount of cash and the aggregate fair value of any property paid out by the Company in connection with any such repurchase or redemption by (y) the number of shares of Common Stock outstanding on a fully diluted basis immediately after such repurchase or redemption and (2) the number of Shares.

- 3 -

6.             Notice of Record Date. In the event:

(1) that the Company declares a dividend (or any other distribution) on any of its capital stock (including without limitation, its Common Stock);

(2) that the Company repurchases or redeems any of its capital stock (including without limitation, its Common Stock) or any rights to acquire such capital stock;

(3) that the Company subdivides or combines its outstanding shares of Common Stock;

(4) of any reclassification of the Common Stock, or of any consolidation, merger or share exchange of the Company into or with another entity, or of the sale of all or substantially all of the assets of the Company;

(5) of the involuntary or voluntary dissolution, liquidation or winding up of the Company; or

(6) of any offer of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Warrant Price then in effect.

then the Company shall notify the Holder at least 30 days prior to the date specified in (A), (B) or (C) below, in writing stating:

(A)         the record date of such dividend, distribution, repurchase, redemption, subdivision or combination, or, if a record is not to be taken, the date as to which the holders of Common Stock of record to be entitled to such dividend, distribution, repurchase, redemption, subdivision or combination are to be determined;

(B)         the date on which such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, dissolution or winding up; or

(C)         the date on which such offering of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Warrant Price is expected to become consummated.

7.             Compliance with Securities Act; Disposition of Warrant or Common Stock.

(a)     Compliance with Securities Act. The Holder, by acceptance hereof, agrees that this Warrant and the Shares to be issued upon exercise hereof are being acquired for investment and that such Holder will not offer, sell or otherwise dispose of this Warrant or any Common Stock to be issued upon exercise hereof except under circumstances which will not result in a violation of the Securities Act of 1933, as amended (the “Act”).

8.             Rights as Shareholders. The Holder shall not, by virtue hereof, be entitled to any rights of a shareholder in the Company, either at law or equity, and the rights of the Holder are limited to those expressed in this Warrant and are not enforceable against the Company except to the extent set forth herein.

The exercise price per share of the Common Stock under this Warrant shall be subject to adjustment hereunder (the “Exercise Price”).

This Warrant is issued in connection with and as consideration for a loan from the initial Holder documented by a promissory note dated XXXXX in the face amount of $XXXX plus origination fee.

1.             Method of Exercise; Payment; Issuance of New Warrant.

(a)     Exercise of Warrant.  Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed facsimile copy of the Notice of Exercise Form annexed hereto; and, within three (3) Trading Days (for purposes herein, “Trading Day” means a day on which any of the following markets or exchanges on which the Common Stock is listed or quoted is open for trading on the date in question (“Trading Market”): the NYSE AMEX, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange or the OTC Markets (or any successors to any of the foregoing)), of the date said Notice of Exercise is delivered to the Company, the Company shall have received payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is delivered to the Company.  Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise Form within one Business Day of receipt of such notice.  In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of manifest error. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

(b)     Mechanics of Exercise.

- 1 -

(i)       Delivery of Certificates Upon Exercise.  Certificates for shares purchased hereunder shall be transmitted by the Transfer Agent (“Transfer Agent” means American Stock Transfer & Trust Company, the current transfer agent of the Company, with a mailing address of 6201-15th Avenue, Brooklyn, New York 11219 and a facsimile number of 718-236-2641, and any successor transfer agent of the Company) to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company through its Deposit Withdrawal Agent Commission (“DWAC”) system if the Company is then a participant in such system and there is an effective Registration Statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder, by the date that is three (3) Trading Days after the latest of (A) the delivery to the Company of the Notice of Exercise Form, (B) surrender of this Warrant (if required) and (C) payment of the aggregate Exercise Price as set forth above (such date, the “Warrant Share Delivery Date”). This Warrant shall be deemed to have been exercised on the first date on which all of the foregoing have been delivered to the Company. The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant to Section 1(c)(vi) prior to the issuance of such shares, having been paid.  If the Company fails for any reason to deliver to the Holder certificates evidencing the Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise), $5 per Trading Day (increasing to $10 per Trading Day on the fifth Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Warrant Share Delivery Date until such certificates are delivered or Holder rescinds such exercise. In the event that there is not an effective Registration Statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder, shares purchased hereunder shall be delivered to the Holder by credit the account of the Holder at the Company’s Transfer Agent by the date that is ten Trading Days after the latest of (A) the delivery to the Company of the Notice of Exercise Form, (B) surrender of this Warrant (if required) and (C) payment of the aggregate Exercise Price as set forth above (such date, the “Warrant Share Delivery Date”).

(ii)       Delivery of New Warrants Upon Exercise.  If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

(iii)      Rescission Rights.  If the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then, the Holder will have the right to rescind such exercise.

(iv)     No Fractional Shares or Scrip.  No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant.  As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

(v)      Charges, Taxes and Expenses.  Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event certificates for Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.

- 2 -

(vi)      Closing of Books.  The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

(vii)     “VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time), (b)  if the OTC Bulletin Board is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board, (c) if the Common Stock is not then listed or quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then reported in the “Pink Sheets” published by OTC Markets, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Company and reasonably acceptable to a majority in interest of the Securities then outstanding, the fees and expenses of which shall be paid by the Company.

2.             Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all preemptive rights, taxes, liens and charges with respect to the issue thereof; provided, however, that the Company shall not be required to pay any transfer taxes with respect to the issue of shares in any name other than that of the registered holder hereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. The Company shall at all times take all such action and obtain all such permits or orders as may be necessary to enable the Company lawfully to issue such Common Stock as duly and validly issued, fully paid and nonassessable shares upon exercise in full of this Warrant.

3.             Adjustment. This Warrant shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a)     Adjustment for Stock Splits and Combinations. If the Company shall at any time or from time to time after the date hereof effect a subdivision of the outstanding Common Stock, the Exercise Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the date hereof combine the outstanding Common Stock, the Exercise Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

(b)     Adjustment for Certain Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Exercise Price shall be decreased as of the time of such issuance, by multiplying the Exercise Price by a fraction:

(x) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance; and

(y) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

- 3 -

(c)     Adjustment of Number of Shares. Upon each adjustment of the Exercise Price pursuant to either Section 4(a) or 4(b) of this Warrant, the number of shares of Common Stock purchasable upon exercise of this Warrant shall be adjusted to the number of shares of Common Stock, calculated to the nearest one hundredth of a share, obtained by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment upon the exercise of the Warrant by the Exercise Price in effect prior to such adjustment and dividing the product so obtained by the new Exercise Price.

(d)     Adjustment for Reclassification, Exchange and Substitution. If the Common Stock issuable upon the exercise of this Warrant are changed into the same or different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reorganization, merger, consolidation or sale of assets, provided for in Section 4(e) below), then and in any such event the Holder shall have the right thereafter to exercise this Warrant into the kind and amount of stock and other securities receivable upon such recapitalization, reclassification or other change, by holders of the number of shares of Common Stock for which this Warrant might have been exercised immediately prior to such recapitalization, reclassification or change.

(e)     Reorganization, Mergers, Consolidations or Sales of Assets. If at any time or from time to time there is a capital reorganization of the Common Stock (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reclassification or exchange of shares provided for in Section 4(d) above) or a merger or consolidation of the Company with or into another entity, or a sale of all or substantially all of the Company’s properties and assets to any other person or entity, then, as a part of such reorganization, merger, consolidation or sale, provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant the number of shares of stock or other securities, money or property of the Company, or of the successor entity resulting from such merger or consolidation or sale, to which a holder of Common Stock deliverable upon conversion would have been entitled on such capital reorganization, merger, consolidation, or sale. The Company shall not effect any reorganization, merger, consolidation or sale unless prior to the consummation thereof each entity or person (other than the Company) that may be required to deliver any cash, securities or other property upon the exercise of this Warrant shall assume, by written instrument delivered to the Holder, the obligation to deliver to the Holder such cash, securities or other property as in accordance with the foregoing provisions the Holder may be entitled to receive. The foregoing provisions of this Section 4(e) shall similarly apply to successive reorganizations, mergers, consolidations and sales.

(f)     No Impairment. The Company will not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of this Section and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the Holder against dilution or other impairment. Without limiting the generality of the foregoing, the Company will not issue any capital stock of any class which is preferred as to dividends or as to the distribution of assets upon the voluntary or involuntary dissolution, liquidation or winding up of the Company.

(g)     Notice of Adjustments. Whenever this Warrant shall be adjusted pursuant to this Section 4, the Company shall make a certificate signed by an officer of the Company setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the new Exercise Price and the type or the number of Shares purchasable after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the Holder.

(3) that the Company subdivides or combines its outstanding shares of Common Stock;

(4) of any reclassification of the Common Stock, or of any consolidation, merger or share exchange of the Company into or with another entity, or of the sale of all or substantially all of the assets of the Company;

(B)         the date on which such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, dissolution or winding up; or

(C)         the date on which such offering of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Exercise Price is expected to become consummated.

5.             Transfer of Warrant.

(a)     Transferability. This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer.  Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled.  The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

- 5 -

(b)     New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 6(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date set forth on the first page of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

(c)     Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

(d)     Understandings or Arrangements. Such Holder is acquiring this Warrant as principal for its own account and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Warrant (this representation and warranty not limiting such Holder’s right to sell the Warrant pursuant to a Registration Statement or otherwise in compliance with applicable federal and state securities laws.) Such Holder is acquiring this Warrant hereunder in the ordinary course of its business.

6.             Miscellaneous.

(a)     No Rights as Stockholder Until Exercise.  This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 1(d)(i).

(b)     Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

(c)     Saturdays, Sundays, Holidays, etc.  If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a business day, then, such action may be taken or such right may be exercised on the next succeeding business day.

(d)     Authorized Shares.

(i)     The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

- 6 -

(ii)     Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment.  Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

(iii)     Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

(e)     Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the provisions of Delaware law.

(f)     Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions upon resale imposed by state and federal securities laws.

(g)     Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice Holder’s rights, powers or remedies.  Without limiting any other provision of this Warrant, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

(h)     Notices. Except as otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including electronic mail and facsimile) and delivered to the applicable party at its address specified opposite its signature below, or at such other address as shall be designated by such party in a written notice to the other. All such notices and communications shall, when mailed, telegraphed, telexed, telecopied or cabled or sent by overnight courier, be effective when deposited in the mails, delivered to the telegraph company, cable company or overnight courier, as the case may be, or sent by telex or telecopier.

(i)      Limitation of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

- 7 -

(j)      Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant.  The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

(k)     Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

(l)      Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holders holding Warrants at least equal to a majority of the Warrant Shares issuable upon exercise of all then outstanding Warrants.

(m)    Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

(n)     Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

IN WITNESS WHEREOF, the Company has caused this Warrant to be executed and delivered by its duly authorized officer on the day and year first above written.

Exhibit 4.21

CONVERTIBLE PROMISSORY NOTE

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR APPLICABLE STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT THERE IS AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

Amount: $	Santa Ana, California
Instrument #:	Issuance Date: _________

FOR VALUE RECEIVED, BIOLARGO, INC., a corporation organized under the laws of the state of Delaware (“Issuer”), promises to pay to the order of ___________________________ (hereafter, together with any subsequent holder hereof, called “Holder”), at its office, at “Holder’s Address” (as that term is defined below), or at such other place as Holder may direct, the “Amount” noted above (the “Loan Amount”), payable on June 1, 2018 (the “Maturity Date”). This convertible note is duly authorized issue of the Issuer, purchased by the initial Holder in the Issuer’s 2015 private securities offering pursuant to the subscription agreement (“Subscription Agreement”) submitted by the original Holder and accepted by the Issuer on the “Issuance Date” noted above (the “Issuance Date”), and designated as its “2015 Convertible Note” (referred to herein as the “Note”). This Note is issued as part of a “Unit”, comprised of this Note and a Series “A” Warrant, at a Unit Price of $______.

The Issuer agrees to pay interest on the unpaid principal amount of the Loan Amount from time to time outstanding hereunder at the following rates per year, compounded annually: (i) before the Maturity Date, whether by acceleration or otherwise, at the rate per annum equal to twelve percent (12%); (ii) after the Maturity Date, until paid, at a rate per annum equal to fifteen percent (15%).

Payments of both principal and interest are to be made in immediately available funds in lawful money of the United States of America, or in Common Stock of the Issuer, as set forth below.

     The Note is subject to the following additional provisions:

1.             Interest. Accrual of interest shall commence as of the Issuance Date. Interest will be paid quarterly on March 20th, June 20th, September 20th, and December 20th (the first quarter pro-rated based on the actual number of days elapsed in said quarter), on the date of the conversion of the Note (mandatory or voluntary, as set forth below), and also on the Maturity Date, such interest to be paid, at the Company’s option, in cash or in that number of shares of Common Stock of the Issuer (the “Common Stock”) at a price per share equal to the average closing price of the Company’s common stock for the 20 trading days preceding a given interest due date (“Interest Conversion Price”). Unless otherwise agreed in writing by both parties hereto, the interest so payable will be paid to the person in whose name this Note (or one or more predecessor Notes) is registered on the records of the Issuer regarding registration and transfers of the Note (the “Note Register”), provided, however, that the Issuer’s obligation to a transferee of this Note arises only if such transfer, sale or other disposition is made in accordance with the terms and conditions contained in this Note and the Subscription Agreement that the original Holder executed at the time of making an investment in the Issuer.

- 1 -

2.             Withholdings. The Issuer shall be entitled to withhold from all payments of principal and/or interest of this Note any amounts required to be withheld under the applicable provisions of the Internal Revenue Code of 1986, as amended, or other applicable laws at the time of such payments.

3.             Transfer. This Note has been issued subject to investment representations of the original Holder hereof and may be transferred or exchanged only in compliance with the Securities Act and applicable state securities laws and in compliance with the restrictions on transfer provided in the Subscription Agreement. Prior to the due presentment for such transfer of this Note, the Issuer and any agent of the Issuer may treat the person in whose name this Note is duly registered in the Note Register as the owner hereof for the purpose of receiving payment as herein provided and all other purposes, whether or not this Note is overdue, and neither the Issuer nor any such agent shall be affected by notice to the contrary. The transferee shall be bound, as the original Holder by the same representations and terms described herein and under the Subscription Agreement.

4.              Conversion by Holder. The Holder may, at its option, at any time convert the principal amount of this Note or any portion thereof, into such number of shares of fully paid and non-assessable Common Stock of the Issuer (“Conversion Shares”) as is obtained by dividing the Loan Amount by the Unit Price set forth in the Subscription Agreement (“Conversion Price”). The right to convert the Note may be exercised by the Holder by telecopying, emailing to ShareholderServices@BioLargo.com, mailing (via first class mail, postage prepaid) or personally delivering an executed and completed notice of conversion (the “Notice of Voluntary Conversion”) to the Issuer. The business day on which a Notice of Voluntary Conversion is delivered in accordance with the provisions hereof shall be deemed the “Voluntary Conversion Date”. The Holder must return to Issuer the original Note. The Issuer shall cause the issuance of the Conversion Shares to an account in Holder’s name at Issuer’s transfer agent, or, upon Holder’s request, issue and deliver a paper certificate representing the Conversion Shares, within ten business days after the later to occur of (i) the Voluntary Conversion Date or (ii) the business day on which the Issuer has received from the Holder the original Note being so converted. Accrued interest shall be due on the Voluntary Conversion Date and paid as set forth above in Paragraph 1.

5.             Conversion by Issuer – Prior to Maturity Date. If the following two conditions are met, the Issuer may, at its option, “call” the Note due and issue shares of its common stock in full payment thereof: (i) the “Conversion Shares” are subject to an effective registration statement filed with the Securities & Exchange Commission, and (ii) the Issuer’s common stock last trades for ten (10) consecutive business days at a value of at least three times the Unit Price. If such conditions are met, the Issuer may require the Holder to convert the principal amount of the Note or any portion thereof, into such number of Conversion Shares as is obtained by dividing the Loan Amount by the Unit Price. The obligation of the Holder to convert the Note may be exercised by the Company by telecopying, emailing, mailing (via first class mail, postage prepaid) or personally delivering an executed and completed notice of conversion (the “Notice of Mandatory Conversion”) to the Holder’s Address maintained in the Note Register. The Holder covenants and agrees to acknowledge a Notice of Mandatory Conversion in writing by completing, dating and signing such Notice of Mandatory Conversion and returning it to the Company by telecopier, electronic mail, first class mail (postage prepaid) or personal delivery (the “Holder Acknowledgment Date”) , along with the original Note. The business day on which a Notice of Mandatory Conversion is delivered in accordance with the provisions hereof shall be deemed the “Mandatory Conversion Date”. The Holder must return to Issuer the original Note. The Issuer will cause the issuance of Conversion Shares to an account in Holder’s name at Issuer’s transfer agent, or, upon Holder’s request, issue and deliver a paper certificate representing the Conversion shares, within ten Business Days after the later to occur of (i) the Holder Acknowledgment Date or (ii) the date that the Issuer has received from the Holder the original Note being so converted. Accrued interest shall be due on the Mandatory Conversion Date and paid as set forth above in Paragraph 1.

- 2 -

6.             Conversion by Issuer – at Maturity. At the Maturity Date, the Issuer may, at its option, require the Holder to convert the principal amount of the Note or any portion thereof, into such number of Conversion Shares as is obtained by dividing the Loan Amount by the Unit Price. The obligation of the Holder to convert the Note may be exercised by the Company by telecopying, emailing, mailing (via first class mail, postage prepaid) or personally delivering an executed and completed notice of conversion (the “Notice of Mandatory Conversion”) to the Holder’s Address maintained in the Note Register. The Holder covenants and agrees to acknowledge a Notice of Mandatory Conversion in writing by completing, dating and signing such Notice of Mandatory Conversion and returning it to the Company by telecopier, electronic mail, first class mail (postage prepaid) or personal delivery (the “Holder Acknowledgment Date”), along with the original Note. The business day on which a Notice of Mandatory Conversion is delivered in accordance with the provisions hereof shall be deemed the “Mandatory Conversion Date”. The Holder must return to Issuer the original Note. The Issuer will cause the issuance of Conversion Shares to an account in Holder’s name at Issuer’s transfer agent, or, upon Holder’s request, issue and deliver a paper certificate representing the Conversion shares, within ten Business Days after the later to occur of (i) the Holder Acknowledgment Date or (ii) the date that the Issuer has received from the Holder the original Note being so converted. Accrued interest shall be due on the Mandatory Conversion Date and paid as set forth above in Paragraph 1.

7.             Reduction of Principal upon Conversion. The principal amount of this Note, and any accrued interest thereon, shall be reduced as per that principal amount indicated on the Notice of Voluntary Conversion or Notice of Mandatory Conversion, as the case may be, upon the proper receipt by the Holder of such Conversion Shares due upon such Notice of Voluntary Conversion or Notice of Mandatory Conversion.

8.             Adjustment. The number of Conversion Shares shall be adjusted as follows. If the Issuer shall at any time subdivide its outstanding shares of Common Stock into a greater number of shares of Common Stock, the number of Conversion Shares in effect immediately prior to such subdivision shall be proportionately increased, and conversely, in case the outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the number of Conversion Shares in effect immediately prior to such subdivision shall be proportionately decreased.

9.             No provision of this Note shall alter or impair the obligation of the Issuer, which is absolute and unconditional, upon an Event of Default (as defined below), to pay the principal of, and interest on this Note at the place, time, and rate, and in the coin or currency herein prescribed.

10.           Events of Default. Each of the following occurrences is hereby defined as an “Event of Default”:

a.     Nonpayment. The Issuer shall fail to make any payment of principal, interest, or other amounts payable hereunder when and as due; or

b.     Dissolutions, etc. The Issuer or any subsidiary shall fail to comply with any provision concerning its existence or any prohibition against dissolution, liquidation, merger, consolidation or sale of assets; or

c.     Noncompliance with this Agreement. The Issuer shall fail to comply in any material respect with any provision hereof, which failure does not otherwise constitute an Event of Default, and such failure shall continue for ten (10) days after the occurrence of such failure; or

d.     Bankruptcy. Any bankruptcy, insolvency, reorganization, arrangement, readjustment, liquidation, dissolution, or similar proceeding, domestic or foreign, is instituted by or against the Issuer or any of its subsidiaries, or the Issuer or any of its subsidiaries shall take any step toward, or to authorize, such a proceeding; or

- 3 -

e.     Insolvency. The Issuer shall make a general assignment for the benefit of its creditors, shall enter into any composition or similar agreement, or shall suspend the transaction of all or a substantial portion of its usual business.

11.           Holder’s Election upon Default. If one or more “Events of Default” shall occur, then, or at any time thereafter, and in each and every such case, unless such Event of Default shall have been waived in writing by the Holder (which waiver shall not be deemed to be a waiver of any subsequent default) or cured as provided herein, at the option of the Holder, and in the Holder’s sole discretion, the Holder may elect to consider this Note (and all interest through such date) immediately due and payable. In order to so elect, the Holder must deliver written notice of the election and the amount due to the Issuer via certified mail, return receipt requested, at the Issuer’s address as set forth herein (or any other address provided to the Holder), and thereafter the Issuer shall have ten business days upon receipt to cure the Event of Default, pay the Note, or convert the amount due on the Note pursuant to the conversion formula set forth above. It is agreed that in the event of such action, such Holder shall be entitled to receive all reasonable fees, costs and expenses incurred, including without limitation such reasonable fees and expenses of attorneys. The parties acknowledge that a change in control of the Issuer shall not be deemed to be an Event of Default as set forth herein.

12.           Invalid or Unenforceable Provisions. In case any provision of this Note is held by a court of competent jurisdiction to be excessive in scope or otherwise invalid or unenforceable, such provision shall be adjusted rather than voided, if possible, so that it is enforceable to the maximum extent possible, and the validity and enforceability of the remaining provisions of this Note will not in any way be affected or impaired thereby.

13.           Voting Rights. This Note does not entitle the Holder hereof to any voting rights or other rights as a stockholder of the Issuer prior to the conversion into Common Stock thereof, except as provided by applicable law. If, however, at the time of the surrender of this Note and conversion the Holder hereof shall be entitled to convert this Note, the Conversion Shares so issued shall be and be deemed to be issued to such holder as the record owner of such shares as of the close of business on the Conversion Date.

IN WITNESS WHEREOF, the Issuer has caused this Note to be duly executed by an officer thereunto duly authorized.

THIS CERTIFIES THAT, for value received, ___________________________ (the “Holder”), is entitled upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the date issued set forth above (the “Exercise Date”) and on or prior to the close of business on June 1, 2020 (the “Termination Date”) but not thereafter, to subscribe for and purchase from BioLargo, Inc., a Delaware corporation (the “Company”), up to ________ shares (the “Warrant Shares”) of common stock, par value, $0.00067, of the Company (the “Common Stock”). The exercise price per share of the Common Stock under this Warrant shall be $_____ subject to adjustment hereunder (the “Exercise Price”).

This Warrant is issued in connection with and as consideration for the initial Holder’s investment in the Company’s private securities offering dated January 1, 2015, titled its 2015 “Unit Offering,” in which the initial Holder purchased a Unit consisting of a convertible promissory note in the principal amount of $_______ and this Series “A” Warrant certificate.

1.     Method of Exercise; Payment; Issuance of New Warrant.

(a)     Exercise of Warrant.  Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed facsimile copy of the Notice of Exercise Form annexed hereto; and, within three (3) Trading Days (for purposes herein, “Trading Day” means a day on which any of the following markets or exchanges on which the Common Stock is listed or quoted is open for trading on the date in question (“Trading Market”): the NYSE AMEX, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange or the OTC Markets (or any successors to any of the foregoing)), of the date said Notice of Exercise is delivered to the Company, the Company shall have received payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is delivered to the Company.  Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise Form within one Business Day of receipt of such notice.  In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of manifest error. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

(b)     Mechanics of Exercise.

(i)     Delivery of Certificates Upon Exercise.  Certificates for shares purchased hereunder shall be transmitted by the Transfer Agent (“Transfer Agent” means American Stock Transfer & Trust Company, the current transfer agent of the Company, with a mailing address of 6201-15th Avenue, Brooklyn, New York 11219 and a facsimile number of 718-236-2641, and any successor transfer agent of the Company) to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company through its Deposit Withdrawal Agent Commission (“DWAC”) system if the Company is then a participant in such system and there is an effective Registration Statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder, by the date that is three (3) Trading Days after the latest of (A) the delivery to the Company of the Notice of Exercise Form, (B) surrender of this Warrant (if required) and (C) payment of the aggregate Exercise Price as set forth above (such date, the “Warrant Share Delivery Date”). This Warrant shall be deemed to have been exercised on the first date on which all of the foregoing have been delivered to the Company. The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant to Section 1(c)(vi) prior to the issuance of such shares, having been paid.  If the Company fails for any reason to deliver to the Holder certificates evidencing the Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise), $5 per Trading Day (increasing to $10 per Trading Day on the fifth Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Warrant Share Delivery Date until such certificates are delivered or Holder rescinds such exercise. In the event that there is not an effective Registration Statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder, shares purchased hereunder shall be delivered to the Holder by credit the account of the Holder at the Company’s Transfer Agent by the date that is ten Trading Days after the latest of (A) the delivery to the Company of the Notice of Exercise Form, (B) surrender of this Warrant (if required) and (C) payment of the aggregate Exercise Price as set forth above (such date, the “Warrant Share Delivery Date”).

(ii)      Delivery of New Warrants Upon Exercise.  If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

(iii)      Rescission Rights.  If the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then, the Holder will have the right to rescind such exercise.

(iv)      Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Exercise.  In addition to any other rights available to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing the Warrant Shares pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder.  For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss.  Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

- 2 -

(v)     No Fractional Shares or Scrip.  No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant.  As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

(vi)     Charges, Taxes and Expenses.  Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event certificates for Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.

(vii)     Closing of Books.  The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

(viii)     “VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time), (b)  if the OTC Bulletin Board is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board, (c) if the Common Stock is not then listed or quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then reported in the “Pink Sheets” published by OTC Markets, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Company and reasonably acceptable to a majority in interest of the Securities then outstanding, the fees and expenses of which shall be paid by the Company.

- 3 -

2.         Call Provision. In the event that both of the following conditions are met (the “Call Conditions”), the Company may “call” this Warrant requiring the Holder purchase all or a portion of the Warrant Shares pursuant to the provisions of this Paragraph: (i) the closing price of the Common Stock for each of ten (10) consecutive business days, equals or exceeds two (2) times the Exercise Price (subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and the like after the date of issuance of this Warrant), and (ii) the Warrant Shares are subject to an effective registration statement (“Registration Statement”) filed with the Securities & Exchange Commission. If the Call Conditions are satisfied concurrently, the Company may, within thirty (30) calendar days of such day, call for cancellation of all or any portion of the remaining Warrant Shares for which a Notice of Exercise Form has not yet been delivered (such right, a “Call”). To exercise this right, the Company must deliver to the registered Holder a written notice (a “Call Notice”), indicating therein the unexercised portion of this Warrant to which such notice applies. In the event a Notice of Exercise Form for any portion of this Warrant subject to such Call Notice shall not have been received by the Company within thirty (30) calendar days after the date of the Call Notice, then such portion shall be forfeited in its entirety without payment or consideration to the registered Holder.  

3.         Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all preemptive rights, taxes, liens and charges with respect to the issue thereof; provided, however, that the Company shall not be required to pay any transfer taxes with respect to the issue of shares in any name other than that of the registered holder hereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. The Company shall at all times take all such action and obtain all such permits or orders as may be necessary to enable the Company lawfully to issue such Common Stock as duly and validly issued, fully paid and nonassessable shares upon exercise in full of this Warrant.

4.         Adjustment. This Warrant shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a)     Adjustment for Stock Splits and Combinations. If the Company shall at any time or from time to time after the date hereof effect a subdivision of the outstanding Common Stock, the Exercise Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the date hereof combine the outstanding Common Stock, the Exercise Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

(b)     Adjustment for Certain Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Exercise Price shall be decreased as of the time of such issuance, by multiplying the Exercise Price by a fraction:

(x) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance; and

(y) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

(c)     Adjustment of Number of Shares. Upon each adjustment of the Exercise Price pursuant to either Section 4(a) or 4(b) of this Warrant, the number of shares of Common Stock purchasable upon exercise of this Warrant shall be adjusted to the number of shares of Common Stock, calculated to the nearest one hundredth of a share, obtained by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment upon the exercise of the Warrant by the Exercise Price in effect prior to such adjustment and dividing the product so obtained by the new Exercise Price.

- 4 -

(d)     Adjustment for Reclassification, Exchange and Substitution. If the Common Stock issuable upon the exercise of this Warrant are changed into the same or different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reorganization, merger, consolidation or sale of assets, provided for in Section 4(e) below), then and in any such event the Holder shall have the right thereafter to exercise this Warrant into the kind and amount of stock and other securities receivable upon such recapitalization, reclassification or other change, by holders of the number of shares of Common Stock for which this Warrant might have been exercised immediately prior to such recapitalization, reclassification or change.

(e)     Reorganization, Mergers, Consolidations or Sales of Assets. If at any time or from time to time there is a capital reorganization of the Common Stock (other than a subdivision or combination provided for in Section 4(a) above, a dividend or distribution provided for in Section 4(b) above, or a reclassification or exchange of shares provided for in Section 4(d) above) or a merger or consolidation of the Company with or into another entity, or a sale of all or substantially all of the Company’s properties and assets to any other person or entity, then, as a part of such reorganization, merger, consolidation or sale, provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant the number of shares of stock or other securities, money or property of the Company, or of the successor entity resulting from such merger or consolidation or sale, to which a holder of Common Stock deliverable upon conversion would have been entitled on such capital reorganization, merger, consolidation, or sale. The Company shall not effect any reorganization, merger, consolidation or sale unless prior to the consummation thereof each entity or person (other than the Company) that may be required to deliver any cash, securities or other property upon the exercise of this Warrant shall assume, by written instrument delivered to the Holder, the obligation to deliver to the Holder such cash, securities or other property as in accordance with the foregoing provisions the Holder may be entitled to receive. The foregoing provisions of this Section 4(e) shall similarly apply to successive reorganizations, mergers, consolidations and sales.

(f)     No Impairment. The Company will not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of this Section and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the Holder against dilution or other impairment. Without limiting the generality of the foregoing, the Company will not issue any capital stock of any class which is preferred as to dividends or as to the distribution of assets upon the voluntary or involuntary dissolution, liquidation or winding up of the Company.

(g)     Notice of Adjustments. Whenever this Warrant shall be adjusted pursuant to this Section 4, the Company shall make a certificate signed by an officer of the Company setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the new Exercise Price and the type or the number of Shares purchasable after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the Holder.

5.     Notice of Record Date. In the event:

(1) that the Company declares a dividend (or any other distribution) on any of its capital stock (including without limitation, its Common Stock);

- 5 -

(2) that the Company repurchases or redeems any of its capital stock (including without limitation, its Common Stock) or any rights to acquire such capital stock;

(3) that the Company subdivides or combines its outstanding shares of Common Stock;

(4) of any reclassification of the Common Stock, or of any consolidation, merger or share exchange of the Company into or with another entity, or of the sale of all or substantially all of the assets of the Company;

(5) of the involuntary or voluntary dissolution, liquidation or winding up of the Company; or

(6) of any offer of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Exercise Price then in effect.

then the Company shall notify the Holder at least 30 days prior to the date specified in (A), (B) or (C) below, in writing stating:

(A)         the record date of such dividend, distribution, repurchase, redemption, subdivision or combination, or, if a record is not to be taken, the date as to which the holders of Common Stock of record to be entitled to such dividend, distribution, repurchase, redemption, subdivision or combination are to be determined;

(B)         the date on which such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, dissolution or winding up; or

(C)         the date on which such offering of its Common Stock or any rights to acquire such Common Stock for consideration paid per share of Common Stock less than the Exercise Price is expected to become consummated.

6.     Transfer of Warrant.

(a)     Transferability. This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer.  Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled.  The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

(b)     New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 6(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date set forth on the first page of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

- 6 -

(c)     Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

(d)     Understandings or Arrangements. Such Holder is acquiring this Warrant as principal for its own account and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Warrant (this representation and warranty not limiting such Holder’s right to sell the Warrant pursuant to the Registration Statement or otherwise in compliance with applicable federal and state securities laws.) Such Holder is acquiring this Warrant hereunder in the ordinary course of its business.

7.     Miscellaneous.

(a)     No Rights as Stockholder Until Exercise.  This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 1(d)(i).

(b)     Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

(c)     Saturdays, Sundays, Holidays, etc.  If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a business day, then, such action may be taken or such right may be exercised on the next succeeding business day.

(d)     Authorized Shares.

(i)       The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

- 7 -

(ii)      Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment.  Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

(iii)     Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

(e)     Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the provisions of Delaware law.

(f)     Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions upon resale imposed by state and federal securities laws.

(g)     Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice Holder’s rights, powers or remedies.  Without limiting any other provision of this Warrant, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

(h)     Notices. Except as otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including electronic mail and facsimile) and delivered to the applicable party at its address specified opposite its signature below, or at such other address as shall be designated by such party in a written notice to the other. All such notices and communications shall, when mailed, telegraphed, telexed, telecopied or cabled or sent by overnight courier, be effective when deposited in the mails, delivered to the telegraph company, cable company or overnight courier, as the case may be, or sent by telex or telecopier.

(i)      Limitation of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

(j)      Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant.  The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

- 8 -

(k)     Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

(l)      Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holders holding Warrants at least equal to a majority of the Warrant Shares issuable upon exercise of all then outstanding Warrants.

(m)    Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

(n)     Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

We consent to the incorporation by reference in the Registration Statement of BioLargo, Inc. on Form S-8 (File No. 333-153193) of our report dated March 31, 2015, appearing in the Annual Report on Form 10-K of BioLargo, Inc. for the year ended December 31, 2014.

Our report dated March 31, 2015 contains an explanatory paragraph that states the Company has suffered recurring losses, negative cash flows from operations and has limited capital resources and a net stockholders’ deficit. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

Note 2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated.

Cash and Cash Equivalents

We consider all highly liquid investments with original maturities of three months or less or money market funds from substantial financial institutions to be cash equivalents. We place substantially all of our cash and cash equivalents with one financial institution. As of December 31, 2014, our cash deposits were less than the Federal Deposit Insurance Corporation insurance limit of $250,000 per owner. From time to time during the year we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the institution, however, we do not anticipate non-performance.

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts was $3,818 at December 31, 2013 and December 31, 2014.

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. Inventories consisted of:

	December 31, 2013		December 31, 2014
Raw materials	$	26,080	$	18,816
Finished goods		3,750		6,698
	$	29,830	$	25,514

Other Assets

Other Assets consists of payments made to purchase patents related to our efforts in commercializing the ISAN system.

For the years ended December 31, 2013 and 2014 we recorded amortization expense totaling $10,920.

Long-lived and definite lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the expected future undiscounted cash flows from the use of the asset and its eventual disposition is less than the carrying amount of the asset, then an impairment loss is recognized. The impairment loss is measured based on the fair value of the asset. Any resulting impairment is recorded as a reduction in the carrying value of the related asset in excess of fair value and a charge to operating results. For the years ended December 31, 2013 and 2014, management determined that there was no impairment of its long-lived assets.

Equipment

Equipment is carried at cost and depreciated using the straight-line method over the estimated useful lives of the assets which is three years to 7 years. As of December 31, 2013 and 2014, our equipment was fully depreciated.

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the years ended December 31, 2013 and 2014, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company’s net loss.

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, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, uncollectible accounts receivable, asset depreciation and amortization, and taxes, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-based Payments

All share-based payments to employees, including grants of employee stock options, are recognized in the consolidated financial statements based on their fair values.

For stock issued to consultants and other non-employees for services, we record the expense based on the fair market value of the securities as of the date of the stock issuance. The issuance of stock warrants or options to non-employees are valued at the time of issuance utilizing the Black Scholes calculation and the amount is charged to expense.

During the years ended December 31, 2013 and 2014 we recorded an aggregate $39,200 and $25,200 in selling, general and administrative expense related to options issued pursuant to the 2007 Plan.

During the years ended December 31, 2013 and 2014 we recorded an aggregate $892,309 and $846,588 in selling, general and administrative expense related to options issued outside of the 2007 Plan.

During the year ended December 31, 2014 we issued 664,411 shares of our common stock to our President, Chief Technology Officer and Secretary in lieu of accrued and unpaid compensation and unreimbursed expenses totaling $294,798.

During the year ended December 31, 2013 we issued 1,483,764 shares of our common stock to our President, Chief Technology Officer and Secretary in lieu of accrued and unpaid compensation and unreimbursed expenses totaling $419,224.

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

Revenue Recognition

Revenues are recognized as risk and title to products transfers to the customer (which generally occurs at the time shipment is made), the sales price is fixed or determinable, and collectability is reasonably assured. We also may generate revenues from royalties and license fees from our intellectual property. Licensees typically pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. License fees are recognized over the estimated period of future benefit to the average licensee.

IncomeTaxes

The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of asset and liabilities. Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred tax asset and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We account for uncertainties in income tax law under a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns as prescribed by generally accepted accounting principles (“GAAP”). Under GAAP, the tax effects of a position are recognized only if it is “more-likely-than-not” to be sustained by the taxing authority as of the reporting date. If the tax position is not considered “more-likely-than-not” to be sustained, then no benefits of the position are recognized.

Fair Value of Financial Instruments

Management believes the carrying amounts of the Company's financial instruments as of December 31, 2013 and 2014 approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, prepaid assets, accounts payable, convertible notes, and other assets and liabilities.

Recent Accounting Pronouncements

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-08 (ASU 2014-08), Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360). ASU 2014-08 amends the requirements for reporting discontinued operations and requires additional disclosures about discontinued operations. Under ASU 2014-08, only disposals representing a strategic shift in operations or that have a major effect on the Company’s operations and financial results should be presented as discontinued operations. ASU 2014-08 is effective for annual periods beginning after December 15, 2014. As the Company is engaged in research and development activities, the Company does not expect the adoption of this guidance to have any impact on the Company’s financial statement presentation or disclosures.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers. ASU 2014-09 will eliminate transaction- and industry-specific revenue recognition guidance under current U.S. GAAP and replace it with a principle based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize revenue based on the value of transferred goods or services as they occur in the contract. ASU 2014-09 also will require additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for reporting periods beginning after December 15, 2016, and early adoption is not permitted. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the impact the adoption of ASU 2014-09 on the Company’s financial statement presentation and disclosures.

In August 2014, the FASB issued Accounting Standards Update No. 2014-15 (ASU 2014-15), Presentation of Financial Statements – Going Concern (Subtopic 205-10).  ASU 2014-15 provides guidance as to management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related note disclosures.  In connection with preparing financial statements for each annual and interim reporting period, an entity’s management should evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued (or at the date that the financial statements are available to be issued when applicable). Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company is currently evaluating the impact the adoption of ASU 2014-15 on the Company’s financial statement presentation and disclosures.

Note 1. Business and Organization

Outlook

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of our business. As reflected in the accompanying financial statements for the year ended December 31, 2014, we had a net loss of $3,739,567, and, at December 31, 2014, we had negative working capital of $422,347, current assets of $230,591, an accumulated deficit of $79,019,719, and a net stockholders’ deficiency. The foregoing factors raise substantial doubt about our ability to continue as a going concern. Ultimately, our ability to continue as a going concern is dependent upon our ability to attract significant new sources of capital, attain a reasonable threshold of operating efficiencies and achieve profitable operations by licensing or otherwise commercializing products incorporating our BioLargo technology. The financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

We have been, and anticipate that we will continue to be, limited in terms of our capital resources. Our total cash and cash equivalents were $154,460 at December 31, 2014. We generated revenues of $111,547 in the year ended December 31, 2014, which amount was not sufficient to fund our operations. We generally have not had enough cash or sources of capital to pay our accounts payable and expenses as they arise, and have relied on the issuance of stock options and common stock, as well as extended payment terms with our vendors, to continue to operate. We will be required to raise substantial additional capital to expand our operations, including without limitation, hiring additional personnel, additional scientific and third-party testing, costs associated with obtaining regulatory approvals and filing additional patent applications to protect our intellectual property, and possible strategic acquisitions or alliances, as well as to meet our liabilities as they become due for the next 12 months.

As of December 31, 2014, we had $250,000 principal amount outstanding on our notes payable (see Note 5), and $494,938 of outstanding accounts payable. (See Note 10.)

During the year ended December 31, 2014, we received $1,335,644 net proceeds from our private securities offerings. (See Note 4.) We received $245,000 from the sale of stock in our subsidiary Clyra and we also received $200,000 net proceeds from convertible note obligations. (See Note 5.)

In the opinion of management, the accompanying balance sheets and related statements of operations, cash flows, and stockholders’ equity (deficit) include all adjustments, consisting only of normal recurring items, necessary for their fair presentation in conformity with accounting principles generally accepted in the United States of America.

Organization

We were initially organized under the laws of the State of Florida in 1989, and in 1991 merged into a Delaware corporation. We operate five subsidiaries: BioLargo Life Technologies, Inc., organized under the laws of the State of California in 2006, Odor-No-More, Inc., organized under the laws of the State of California in 2009, Clyra Medical Technologies, Inc., organized under the laws of the State of California in 2012, BioLargo Water, Inc., organized under the laws of the State of California in 2013 and BioLargo Water Canada, organized under the laws of Canada in 2014.

Business Overview 

We feature three patent protected platform technologies with diverse product opportunities across multiple industries – the AOS Filter, CupriDyne, and Isan. Each features the use of the all-natural iodine molecule. While they all use iodine, they are quite different in terms of the methods by which they exploit the use of iodine, the form and composition of iodine used, and therefore their function and value proposition can be quite different for each commercial application.

Note 11. Provision for Income Taxes

Given our historical losses from operations, income taxes have been limited to the minimum franchise tax assessed by the State of California.

At December 31, 2014, we had federal and California tax net operating loss carry-forwards of approximately $42 million. Due to changes in our ownership through various common stock issuances during 2002 and 2007, the utilization of net operating loss carry-forwards may be subject to annual limitations and discounts under provisions of the Internal Revenue Code. Such limitations could result in the permanent loss of a significant portion of the net operating loss carry-forwards. Realization of our deferred tax assets, which relate to operating loss carry-forwards and timing differences, is dependent on future earnings. The timing and amount of future earnings are uncertain and therefore we have established a 100% valuation allowance.

At December 31, 2014, our U.S. Federal and California State income tax returns related to the years 2010-2013 remain open to examination by tax authorities. However, given our history of net operating losses, as discussed above, the statute of limitations could remain open to examine years prior to 2007 for the year(s) in which net operating losses were originally incurred if/when we reach profitability and begin to utilize our net operating losses to offset taxable income.

Note 5. Notes and Convertible Notes Payable

In December 2014, we received $200,000 and issued convertible promissory notes with a maturity date in December 2015, which accrue interest at a rate of 12% per annum. Each noteholder, for no additional consideration, received a stock purchase warrant exercisable at $0.30 per share, which right terminates three years after the date of issuance. We issued warrants to purchase an aggregate 350,000 shares. Each noteholder may exchange the note for the securities offered in our current private securities offering.

The fair value of the warrants and the intrinsic value of the beneficial conversion feature resulted in a $200,000 discount on the note payables, of which $8,000 was amortized as interest expense for the year ended December 31, 2014.

On November 19, 2013, we received $50,000 pursuant to a line of credit whereby we have pledged our inventory and accounts receivable as collateral. The maturity date of the line of credit is May 15, 2015, which accrues interest at a rate of 24%. We incurred an additional $4,000 in fees upon executing the line of credit, which was recorded as interest expense during the year ended December 31, 2013.

Our stock price on the date of issuance was $0.43 per share, resulting in an additional financing costs of $244,800 which was recorded as interest expense.

On June 8, 2010, we received $100,000 and issued a promissory note with an initial maturity date of December 3, 2010, which accrues interest at a rate of 10%. The noteholder, for no additional consideration, received a stock purchase warrant entitling the holder to purchase 50,000 shares of our common stock, exercisable at $0.50 per share until June 3, 2013. (See Note 7.) The maturity date of the note was extended to December 3, 2011, to December 3, 2012. On December 28, 2012, the note holder agreed to extend the maturity date of the note by a period of one year to December 31, 2013. As consideration for the extension, we issued the noteholder 60,000 shares of our common stock at $0.25 per share and recorded $15,000 in interest expense, and a warrant to purchase 50,000 shares of common stock at $0.50 cents per share, exercisable until June 3, 2014. The fair value of this warrant totaled $6,805 and was recorded as interest expense. (See Note 7.) On December 31, 2013, the note holder agreed to extend the maturity date of the note January 14, 2015. As consideration for the extension, we issued the noteholder 60,000 shares of our common stock at $0.25 per share and recorded $15,000 in interest expense, and a warrant to purchase 60,000 shares of common stock at $0.30 cents per share, exercisable until January 14, 2017.

Outstanding as of December 31, 2014		8,838,122		$0.125	-	1.00

To determine interest expense related to our outstanding warrants issued in conjunction with debt offerings, the fair value of each award grant is estimated on the date of grant using the Black-Scholes option-pricing model and the calculated value is amortized over the life of the warrant. The determination of expense of warrants issued for services or settlement also uses the option-pricing model. The principal assumptions we used in applying this model were as follows:

	2013			2014
Risk free interest rate	0.15 %	-	0.78%	0.09%	-	1.55%
Expected volatility	112%	-	262%	184%	-	349%
Expected dividend yield		--			--
Forfeiture rate		--			--
Expected life in years	1	-	3	1	-	5

The risk-free interest rate is based on U.S Treasury yields in effect at the time of grant. Expected volatilities are based on historical volatility of our common stock.

We recorded $247,412 and $8,000 of interest expense related to the amortization of the discount on convertible notes, for the extension of warrants set to expire, and for the fair value of warrants issued for services for the years ended December 31, 2013 and 2014, respectively.

Warrants Issued concurrently with Convertible Note Payables.

See Note 4 for a description of warrants to purchase an aggregate 350,000 shares of our common stock at $0.30 per share issued in December 2014.

Per the terms of the Summer 2014 offering and through the year ended December 31, 2014, we issued warrants to purchase 717,500 shares of our common stock. The warrant is exercisable at $0.75 per share, will expire on July 31, 2019, and is subject to a call provision in the event (i) the closing price of the Common Stock for each of twenty (20) consecutive business days, exceeds $1.50 per share (subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and the like after the date of issuance of this Warrant), (ii) the Restricted Stock is subject to resale pursuant to 17 C.F.R. 230.144 (“Rule 144”) or pursuant to any other exemption from registration under to the Securities Act of 1933, as amended and (iii) the Shares underlying the Warrant are registered with the SEC.

Note 9. Stock-Based Compensation and Other Employee Benefit Plans

2007 Equity Incentive Plan

On August 7, 2007, and as amended April 29, 2011, our Board of Directors adopted the BioLargo, Inc. 2007 Equity Incentive Plan (“2007 Plan”) as a means of providing our directors, key employees and consultants additional incentive to provide services. Both stock options and stock grants may be made under this plan. The Compensation Committee administers this plan. The plan allows grants of common shares or options to purchase common shares. As plan administrator, the Compensation Committee has sole discretion to set the price of the options. The Compensation Committee may at any time amend or terminate the plan.

On June 23, 2014, we issued an option purchase an aggregate 40,000 shares of our common stock to the independent members of our Board of Directors, pursuant to the terms of the 2007 Equity Plan which calls for an annual automatic issuance. Each board member received an option to purchase 10,000 shares of our common stock, the option vests after a period of one year from the date of grant, expires ten years from the date of issuance, and is exercisable at $0.63 per share, the price of our common stock on the grant date. The fair value of this option totaled $25,200 and was recorded as selling, general and administrative expense.

On June 17, 2013, we issued an option to purchase an aggregate 40,000 shares of our common stock to our members of our Board of Directors, pursuant to the terms of the 2007 Equity Plan which calls for an annual automatic issuance. Each board member received an option to purchase 10,000 shares of our common stock, the option vests after a period of one year from the date of grant, expires ten years from the date of issuance, and is exercisable at $0.28 per share, the price of our common stock on the grant date. The fair value of this option totaled $11,200 and was recorded as selling, general and administrative expense.

We recognize compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model. The following methodology and assumptions were used to calculate share based compensation for each of the years ended December 31, 2013 and 2014:

	2013							2014
	Non Plan				2007 Plan			Non Plan				2007 Plan
Risk free interest rate	2.66	-	3.04	%		2.19	%	2.25	-	2.76	%		2.63	%
Expected volatility	928	-	951	%		928	%	837	-	935	%		927	%
Expected dividend yield		--				—			--				—
Forfeiture rate		--				—			--				—
Expected life in years		10				10			10				10

Expected price volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Expected volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility.

The risk-free interest rate used in the Black-Scholes calculation is based on the prevailing U.S Treasury yield as determined by the U.S. Federal Reserve. We have never paid any cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future. The expected life in years is presumed to be the mid-point between the vesting and the end of the contractual term.

Historically, we have not had significant forfeitures of unvested stock options granted to employees and Directors. A significant number of our stock option grants are fully vested at issuance or have short vesting provisions. Therefore, we have estimated the forfeiture rate of our outstanding stock options as zero.

Accounting Policies, by Policy (Policies)

12 Months Ended

Dec. 31, 2014

Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

We consider all highly liquid investments with original maturities of three months or less or money market funds from substantial financial institutions to be cash equivalents. We place substantially all of our cash and cash equivalents with one financial institution. As of December 31, 2014, our cash deposits were less than the Federal Deposit Insurance Corporation insurance limit of $250,000 per owner. From time to time during the year we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the institution, however, we do not anticipate non-performance.

Receivables, Policy [Policy Text Block]

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts was $3,818 at December 31, 2013 and December 31, 2014.

Inventory, Policy [Policy Text Block]

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. Inventories consisted of:

	December 31, 2013		December 31, 2014
Raw materials	$	26,080	$	18,816
Finished goods		3,750		6,698
	$	29,830	$	25,514

Intangible Assets, Finite-Lived, Policy [Policy Text Block]

Other Assets

Other Assets consists of payments made to purchase patents related to our efforts in commercializing the ISAN system.

For the years ended December 31, 2013 and 2014 we recorded amortization expense totaling $10,920.

Long-lived and definite lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the expected future undiscounted cash flows from the use of the asset and its eventual disposition is less than the carrying amount of the asset, then an impairment loss is recognized. The impairment loss is measured based on the fair value of the asset. Any resulting impairment is recorded as a reduction in the carrying value of the related asset in excess of fair value and a charge to operating results. For the years ended December 31, 2013 and 2014, management determined that there was no impairment of its long-lived assets.

Property, Plant and Equipment, Policy [Policy Text Block]

Equipment

Equipment is carried at cost and depreciated using the straight-line method over the estimated useful lives of the assets which is three years to 7 years. As of December 31, 2013 and 2014, our equipment was fully depreciated.

Earnings Per Share, Policy [Policy Text Block]

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the years ended December 31, 2013 and 2014, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company’s net loss.

Use of Estimates, Policy [Policy Text Block]

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, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, uncollectible accounts receivable, asset depreciation and amortization, and taxes, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Share-based Payments

All share-based payments to employees, including grants of employee stock options, are recognized in the consolidated financial statements based on their fair values.

For stock issued to consultants and other non-employees for services, we record the expense based on the fair market value of the securities as of the date of the stock issuance. The issuance of stock warrants or options to non-employees are valued at the time of issuance utilizing the Black Scholes calculation and the amount is charged to expense.

During the years ended December 31, 2013 and 2014 we recorded an aggregate $39,200 and $25,200 in selling, general and administrative expense related to options issued pursuant to the 2007 Plan.

During the years ended December 31, 2013 and 2014 we recorded an aggregate $892,309 and $846,588 in selling, general and administrative expense related to options issued outside of the 2007 Plan.

During the year ended December 31, 2014 we issued 664,411 shares of our common stock to our President, Chief Technology Officer and Secretary in lieu of accrued and unpaid compensation and unreimbursed expenses totaling $294,798.

During the year ended December 31, 2013 we issued 1,483,764 shares of our common stock to our President, Chief Technology Officer and Secretary in lieu of accrued and unpaid compensation and unreimbursed expenses totaling $419,224.

Non-Cash Transactions [Policy Text Block]

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition

Revenues are recognized as risk and title to products transfers to the customer (which generally occurs at the time shipment is made), the sales price is fixed or determinable, and collectability is reasonably assured. We also may generate revenues from royalties and license fees from our intellectual property. Licensees typically pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. License fees are recognized over the estimated period of future benefit to the average licensee.

Income Tax, Policy [Policy Text Block]

IncomeTaxes

The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of asset and liabilities. Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred tax asset and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We account for uncertainties in income tax law under a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns as prescribed by generally accepted accounting principles (“GAAP”). Under GAAP, the tax effects of a position are recognized only if it is “more-likely-than-not” to be sustained by the taxing authority as of the reporting date. If the tax position is not considered “more-likely-than-not” to be sustained, then no benefits of the position are recognized.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of Financial Instruments

Management believes the carrying amounts of the Company's financial instruments as of December 31, 2013 and 2014 approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, prepaid assets, accounts payable, convertible notes, and other assets and liabilities.

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncements

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-08 (ASU 2014-08), Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360). ASU 2014-08 amends the requirements for reporting discontinued operations and requires additional disclosures about discontinued operations. Under ASU 2014-08, only disposals representing a strategic shift in operations or that have a major effect on the Company’s operations and financial results should be presented as discontinued operations. ASU 2014-08 is effective for annual periods beginning after December 15, 2014. As the Company is engaged in research and development activities, the Company does not expect the adoption of this guidance to have any impact on the Company’s financial statement presentation or disclosures.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers. ASU 2014-09 will eliminate transaction- and industry-specific revenue recognition guidance under current U.S. GAAP and replace it with a principle based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize revenue based on the value of transferred goods or services as they occur in the contract. ASU 2014-09 also will require additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for reporting periods beginning after December 15, 2016, and early adoption is not permitted. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the impact the adoption of ASU 2014-09 on the Company’s financial statement presentation and disclosures.

In August 2014, the FASB issued Accounting Standards Update No. 2014-15 (ASU 2014-15), Presentation of Financial Statements – Going Concern (Subtopic 205-10).  ASU 2014-15 provides guidance as to management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related note disclosures.  In connection with preparing financial statements for each annual and interim reporting period, an entity’s management should evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued (or at the date that the financial statements are available to be issued when applicable). Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company is currently evaluating the impact the adoption of ASU 2014-15 on the Company’s financial statement presentation and disclosures.

Deposit Liabilities Disclosures [Text Block]

Note 3. Customer Deposit

In 2012, we executed a joint venture agreement with Peter Holdings Ltd., the principal funding source of the development of the Isan System, whereby we jointly purchased the intellectual property associated with the Isan System, and agreed to share any royalties from the intellectual property on an equal 50/50 basis. In February 2014, we received a deposit of $100,000 from InsulTech Manufacturing, LLC, an Arizona limited liability company d/b/a Clarion Water (“Clarion Water”) towards a worldwide, exclusive license of the Isan System. On August 12, 2014, we entered into a license agreement with Clarion Water in which we granted an exclusive license to commercialize the Isan System. The license agreement provides that the $100,000 deposit is non-refundable, and is to be credited to future payments of royalties or sublicense fees due under the license agreement. The agreement further provides for a 10% royalty of licensee’s “net sales revenue”, and 40% of sublicensing fees. Licensee is required to make minimum payments beginning July 1, 2016, of $50,000 per quarter, and we are obligated to share any revenues under the agreement on an equal basis with Peter Holdings Pty. Ltd. The intellectual property subject to the license agreement includes all intellectual property related to the Isan System, including all patents, trademarks, proprietary knowledge, and other similar know-how or rights relating to or arising out of the Isan System or the patents related to the Isan System. The agreement contains other terms and conditions typically found in intellectual property license agreements.

On March 24, 2011, we entered into a contract in which Central Garden & Pet Company (“Central”) was granted the exclusive worldwide right and license to sell, market, offer for sale, distribute import, export, and otherwise exploit products that contain the BioLargo technologies in the “pet supplies industry” (which is defined in the agreement, and does not include products for equine or livestock). Pursuant to the Central contract, we received a $100,000 non-refundable deposit which would be credited against future orders, if any.  On February 11, 2013, we gave Central written notice of their failure to purchase the minimum required product from us to maintain exclusive rights to our technology in the “pet supplies industry” pursuant to the agreement. To maintain exclusive rights, within 60 days of our written notice Central must have either purchased the minimum amount of product or compensate us for lost profits as if they had done so. Central failed to purchase products from us prior to the expiration of the 60-day period, and failed to otherwise compensate us for lost profits. As such, as of April 12, 2013, Central lost its exclusive rights to our technology in the “pet supplies industry”, and we recorded as revenue the $100,000 deposit paid in 2011.

Subsequent Events [Abstract]

Subsequent Events [Text Block]

Note 13. Subsequent Events

Management has evaluated subsequent events through the date of the filing of this Annual Report and management noted the following for disclosure.

Note Payables

In January 2015, we received $133,000 and issued convertible promissory notes with a maturity date in January 2016, which accrue interest at a rate of 12% per annum. Each noteholder, for no additional consideration, received a stock purchase warrant exercisable at $0.30 per share, which right terminates three years after the date of issuance. We issued warrants to purchase an aggregate 266,000 shares. Each noteholder may exchange the note for the securities offered in our current private securities offering.

2015 Unit Offering

On January 15, 2015, we commenced a private securities offering of “units”, each Unit consisting of a convertible promissory note and “Series A” stock purchase warrant. The price and availability of the Units are set forth in a “pricing supplement” issued from time-to-time, and priced up to a 30% discount to the market price of the Company’s common stock. The Offering is subject to an over-allotment of 20%, or an additional $1,000,000 in Units, for an aggregate total of $6,000,000, and shall be known as the Company’s 2015 “Unit Offering.” The Company has the right to register the common shares underlying the notes and warrants (“Shares”) with the Securities and Exchange Commission, and the obligation to register the Shares in the event gross proceeds of $3,000,000 are raised in the Offering.

Purchasers of the Units will receive a convertible promissory note bearing interest at the rate of 12% per annum on the amount invested. Any interest due will be paid quarterly in arrears in cash or shares of common stock. If paid by the issuance of common stock, interest is paid at a conversion price equal to the average closing price of the Company’s common stock over the 20 trading days prior to the interest payment due date. The principal amount of the note may be paid by the issuance of shares of common stock, or cash, upon maturity at the Company’s election. When paid in shares, the number of shares to be issued shall be calculated by dividing the principal amount invested by the Unit price, as it is established at the time of the original investment by the applicable Pricing Supplement. Notes may be converted at any time by the investor, at maturity by the Company, or by the Company prior to maturity, so long as all of the following conditions are met: (i) the Shares issued as payment are registered with the SEC, (ii) the Company’s common stock closes for ten consecutive trading days at or above three times the Unit price. Notes mature on June 1, 2018.

In addition to the convertible promissory note, each investor will receive a “Series A Warrant” allowing for the purchase of the number of common shares equal to the investment amount divided by the Unit price, (e.g., one warrant share for each share of common stock which the investor is eligible to receive through conversion of his original convertible note) and, the warrant will have an exercise price as set forth in the pricing supplement. Each Series A Warrant expires June 1, 2020. The Company may “call” the Series A Warrant, requiring the investor to exercise the warrant within 30 days or forever lose the rights to do so, only if the following conditions have been met: (i) the underlying Shares are registered with the SEC, and (ii) the Company’s common stock closes for 10 consecutive trading days at or above two times the exercise price.

As of March 30, 2015, we received $255,000 from seven investors pursuant to a Pricing Supplement at $0.25 per Unit. We issued Series A Warrants to purchase an aggregate 1,020,000 shares at an exercise price of $0.40 per share.
