Our Business

General
 
The Company (Chembio Diagnostics, Inc. and its wholly-owned subsidiary Chembio Diagnostic Systems, Inc. are collectively referred to herein as the “Company”"Company") develops, manufactures, markets and licenses rapid point-of-care diagnostic tests (POCTs) that detect infectious diseases.  The Company’sCompany's main products presently commercially available are four rapid tests for the detection of HIV 1/2 antibodies, two rapid tests for the detection of syphilis, and a multiplex rapid test for the detection of canine leishmaniasis.  Three of the HIV and Syphilis antibodies.  The HIV 1/2 rapid tests employ in-licensed and proprietary lateral flow technologies (see “Our"Our Rapid Test Technologies”Technologies"), can be used with all blood matrices as samples, and are manufactured in a standard cassette format, a dipstick format, and a proprietary barrel format.  The tests employing the cassette and proprietary barrel formats were approved by the FDA in 2006 and are2006. The barrel format is exclusively distributed by Alere, Inc. (“Alere”)a distributor in the United States and by Chembio and its designated distributors outside the United States. The exclusive U.S. distribution agreement for the barrel product terminates in accordance with its terms on May 31, 2016.  Chembio and any newly designated distributors will distribute the product in the U.S. after May 31, 2016.  The Cassette format is distributed by Chembio and its designated distributors worldwide.  Our fourthlatest generation HIV 1/2 rapid HIVantibody detection test incorporates our patented Dual Path Platform® (DPP®), POCT technology, and this POCT platform does not require in-licensing.  The DPP® HIV test,1/2 Assay detects antibodies to HIV 1 & 2 in oral fluid samples as well as in all blood matrices.  We have sold this product in Brazil since 2009 where it was approved by ANVISA, through our agreement with the Oswaldo Cruz Foundation ("FIOCRUZ"), and we received United States FDA regulatory approval for this product onin December 19, 2012 and we anticipate launchingCLIA waiver in October 2014.  We launched it in the United States under Chembio’sChembio's brand in 2013.the fourth quarter of 2014.

Our new product pipeline, which currently includes a multiplex rapid teststest for Syphilis and Hepatitis-C,earlier detection of HIV by detecting P-24 antigen as well as antibodies, a test for Hepatitis-C, and a multiplex test that detects HIV and Syphilis specific antibodies (which we are already selling outside the U.S.), is based on this DPP® technology for which we were issued a United States patent in 2007 and for which additional patent protection has issued or is pending worldwide.in a number of other countries.  With the patented DPP® proprietaryand the lateral flow platform, we can participate in the estimated $8-10$8 billion point-of-care market segment of the estimated nearly $50 billion global in-vitro diagnostic market that has an overall growth rate of approximately 7%exceeding 3% per annum.  POCTs, by providing prompt and early diagnosis, can reduce patient stays, lower overall costs, improve therapeutic interventions and improve patient outcomes as a result of prompt and early diagnosis.  Theyoutcomes.  POCTs can also prevent needless hospital admissions, simplify testing procedures, avoid delays from central lab batching, and eliminate the need for return visits.
 
In the areas of infectious and sexually transmitted diseases (such as HIV and syphilis for example)syphilis), the utility of a rapid point–of-care (POC) test, particularly in identifying patients unaware of their disease status, has been well established.  Large and growing markets have been established for these kinds of tests, initially in high prevalence regions where they are indispensable for large scale prevention and treatment programs.  More recently introduced in the United States in 2004, rapid HIV tests now also present a significant segment of the U.S. market for HIV clinical testing, which is still dominated by laboratory tests.  We have focused our product development activity within areas where the availability of rapid, point-of-care screening, diagnostic, or confirmatory results can improve health outcomes.  More generally we believe there is and will continue to be a growing demand for diagnostic products that can provide accurate, actionable diagnostic information in a rapid, cost-effective manner at the point of care.
 
PRODUCTS
 
Lateral Flow Rapid HIV Tests
 
All three of our lateral flow rapid HIV antibody detection tests are qualitative “yes/no”"yes/no" tests for the detection of antibodies to HIV 1 & 2 with visually interpreted results (one line “negative”"negative"; two lines “positive”one line "positive") available within approximately 15 minutes.  The tests are simple to use, have a shelf life of 24 months, and do not require refrigeration. The tests differ principally only in the method of test procedure, convenience and cost.  One of our FDA-approved lateral flow HIV tests incorporates a proprietary plastic “barrel”"barrel" device that houses the lateral flow strip.  This barrel format enables collection of samples directly (for example directly(usually from a finger-stick whole blood sample) into the barrel’sbarrel's capillary tip.  A sealed unitized buffer vial, assembled onto the top of the barrel, is removed and seated into a stand; the seal is then pierced by the barrel’sbarrel's capillary tip, thereby initiating the upward flow of the resulting sample-buffer solution through a filter, up into the vertical device’sdevice's chamber and onto the lateral flow strip.  This results in a unique unitized and closed device system that can reduce the chance of exposure to potentially infectious samples.  We believe
In January 2015, the Company entered into an agreement with StatSure Diagnostic Systems, Inc. (SDS) to acquire SDS' interest in the barrel device format, also known as Chembio's SURE CHECK® HIV 1/2 Assay, effective June 1, 2016. Beginning June 1, 2016, Chembio will own full rights related to the SURE CHECK® HIV 1/2 Assay, including sales, marketing, distribution and trademark rights, subject to the terms of the existing marketing and distribution agreement with Alere, Inc., which grants Alere U.S. marketing and distribution rights through May 31, 2016. Prior to this newly-executed agreement between SDS and Chembio, SDS has owned a 50 percent interest in the rights to the SURE CHECK® HIV 1/2 Assay that this format maywould have continued after May 31, 2016, also subject to the existing marketing and distribution agreement with Alere. The new agreement with SDS also resolves all other matters between Chembio and SDS, including their respective sharing ratios, until June 1, 2016, concerning net revenues from sale of the SURE CHECK® product outside the U.S.

The Company's SURE CHECK® HIV 1/2 Assay is marketed exclusively in the U.S. as Clearview® Complete pursuant to an exclusive distribution agreement that terminates in accordance with its terms on May 31, 2016.  After May 31, 2016, it will be an ideal candidatemarketed in the U.S. as an over-the-counterSure Check® HIV test1/2 Assay. Outside the U.S., Chembio markets the SURE CHECK® HIV 1/2 Assay primarily through distributors. The SURE CHECK® HIV 1/2 Assay is Food & Drug Administration (FDA) approved, CLIA-waived, European CE-marked, and wehas been pre-qualified by the World Health Organization (WHO). Results are participatingobtained in certain studies that should help to better ascertain this.  15 minutes via a 2.5uL blood sample (i.e., fingerstick, serum, plasma, or venipuncture whole blood). The assay is stable at room temperature and provides 99.7% sensitivity and 99.9% specificity.
Our other FDA-approved lateral flow HIV test uses a more conventional rectangular plastic cassette format that houses the lateral flow strip.  In this case, a sample is transferred by use of a separately provided transfer device (“loop”("loop") into a sample well or port of the cassette that houses the lateral flow strip, which is positioned horizontally or flat.
 
Both of the above-described products are marketed exclusively in the United States by Alere as Clearview® Complete HIV 1/2 (the barrel format) and Clearview® HIV 1/2 STAT PAK® (the cassette format), and by Chembio in all other markets under the names Chembio Sure Check® HIV 1/2 and Chembio HIV 1/2 STAT PAK®.  Alere has non-exclusive rights to the barrel product outside the United States.
Our third lateral flow HIV test, the HIV 1/2 STAT PAK® Dipstick, is our most cost competitive and compact format.  It does not have any plastic housing so that 30 test strips can be packaged into a small vial that is ideal for transporting into remote settings.  The test procedure is similar to the cassette format; anformat except that a user-applied adhesive backing is provided as a more cost-effective and compact “housing”"surface" on which to run the test.

Regulatory Status of the lateral flow HIV tests:tests
The FDA approved our Pre-Market Applications (hereinafter “PMA”"PMA"; see “Governmental Regulations”"Governmental Regulations" and Glossary) in April 2006 for our SURE CHECKCHECK® HIV 1/2 (and also now Alere Clearview® Complete HIV 1/2) and for our HIV 1/2 STAT-PAK (now Alere’ Clearview® HIV 1/2 STAT-PAK in the United States only)STAT-PAK® products.  Waivers under the Clinical Laboratory Improvement Act (hereinafter “CLIA”"CLIA"; see Governmental Regulations) were granted by the FDA for thethese two FDA- approvedFDA-approved products in 2006 and 2007, respectively.  TheA CLIA waiver is required in order for health care providers to administer these tests in the settings where they are most suited and needed, such as public health testing clinics, hospital emergency rooms and physicians’physicians' offices.  The SURE CHECK® and HIV 1/2 STAT-PAK®  products received  CE Marks in July 2013 and March 2014, respectively, and the CE Marking for the DPP® HIV 1/2 Assay described below is expected in 2016. We have also updated our filing for CE Marking to reflect the new tradename of STAT-VIEW® HIV 1 / 2 Assay for sale in the EU market.  Our HIV 1/2 STAT-PAKSTAT-PAK® Dipstick, thoughalthough not FDA-approved, qualifies under FDA export regulations [See Government Regulation] to sell to customers outside the United States, subject to any required approval by the importing country.  CE Mark has not been pursued for this product.
 
All three of our lateral flow HIV tests have qualified for procurement under the President’sPresident's Emergency Plan for AIDS Relief (“PEPFAR”("PEPFAR").  The STAT PAK (both the cassette and dipstick versions)versions of the STAT-PAK® and the SURE CHECK® assays are also qualifiedpre-qualified by the World Health Organization (WHO) for procurements by the second largest global program, known as the Global Fund, as well as other related programs funded by agencies affiliated with the United Nations, such as UNICEF and UNITAIDS (see Glossary), through qualification with the WHO bulk procurement scheme.
 
DPP® HIV Test
1/2 Assay
 
As in the case of our lateral flow HIV tests, our DPP® HIV test1/2 Assay is also a qualitative “yes/no”"yes/no" test for the detection of antibodies to HIV 1& 2, delivers visual results within approximatelyas little as 15 minutes, is simple to use, has a shelf life of 2423 months, and does not require refrigeration.  Additionally thisThis product, which is our first FDA-approved product incorporating our patented DPP® technology, can be used with oral fluid samples, as well as with all blood matrices.  This product also incorporates our patent-pending oral fluid collection and storage system that enables samples to be fully extracted in buffer solution before application to the test device, and also enables the extracted sample to be stored and retested or potentially tested for multiple conditions.conditions in future product applications.  Clinical and laboratory studies which uniquely includeddemonstrated the ability of the test subjectsto accurately detect the presence of antibodies in individuals down to two years of age,age. Studies have also shown this product to have improved performance compared with all of the current FDA-approved CLIA-waived lateral flow rapid tests, even including our own lateral flow tests.  FDA-approved label claims include sensitivity/specificity on oral fluid and finger-stick whole blood of 98.9%/99.9% and 99.9%/100% respectively. Oral fluid sensitivity was 100% among HIV-positive patients not taking anti-retroviral medication.
 
Regulatory Status:  In April 2012 we completed a 3,000 patient clinical study with ourStatus of the DPP® HIV test in the United States which we had begun in 2010.  1/2 Assay
In June 2012 we submitted the third of three modules required for a modular PMA application to the FDA.  On December 19, 2012, we received FDA approval of our Pre-Marketing Approval.   DuringIn October of 2014 the first quarter of 2013, we plan to conduct the additional testing necessary in order to complete a CLIA waiver application for this product.  We anticipate that we will be able to complete this testing and complete this application in order to launch the product in the third or fourth quarter of 2013.FDA granted CLIA-waiver status.
 
The DPP® HIV 1/2 Assay product is qualified for procurement under the President’sPresident's Emergency Plan for AIDS Relief (“PEPFAR”("PEPFAR") for use with all sample matrices, and we are pursuing WHO qualification in order to enable procurement of this product by the Global Fund and United Nations agencies, including programs underwritten by them.  In October 2014, we completed a three-day on-site inspection by the WHO as follow-up to pre-qualification activities of our products with no major non-conformances noted during the audit.  The WHO laboratory evaluation for the blood matrix is complete, while oral fluid is in progress and expected to be complete in 2016.  In May 2015 we received approval for a CE Mark for the DPP® HIV 1/2 Assay for Oral Fluid, Serum, Plasma, Fingerstick Whole Blood and Venous Whole Blood.
 
In June 2010, ANVISA approved the DPP® HIV test1/2 Assay that is being marketed in Brazil through our collaboration with the Oswaldo Cruz Foundation, Brazil’sBrazil's leading public health institute.  Given the oral fluid feature,institute (see Oswaldo Cruz Foundation OEM DPP® Agreements).  Since this time, we believehave sold and marketed millions of DPP® HIV tests to Brazil through this product can be marketed as a premium-priced product that will address those market segments in the U.S. and globally that express a preference for a less invasive testing experience.partnership.

This product, pipeline current includes a multiplex Syphilis Screen & Confirm test, a rapid test for the detection of Hepatitis-C antibodies and antigens, and a multiplex testlaunched in 2013, allows for the detection of antibodies to both HIV and Syphilis.  As mentioned below (“Our Rapid Test Technologies”)Syphilis on a single test device within approximately 15 minutes.  In certain global/public health settings (see Target Markets), this product may provide a more convenient and cost-effective means of rapid detecting both markers in a single test procedure at the point of care as compared with performing separate rapid tests for each indication.  This product takes advantage of the multiplexing feature of DPP® which provides for a more robust reaction between the sample and biomarkers being tested for (HIV and Syphilis antibodies in this case), resulting in a greater ability by the user to visually interpret test results.  We launched this product in Mexico in the fourth quarter of 2013 as a unitized product, meaning that each test kit was separately packaged to include each of the other components necessary to run this test, as compared with other configurations where a test kit of 20 or 30 devices is accompanied by one bottle of running buffer.  The initial results of this launch have been very positive, and we also are considering developmentexperienced  good results in Mexico during 2014 from the program. Building on this initial success, we continue to pursue commercialization efforts for this product in a number of so-called “Fourth Generation” tests that are ableadditional international markets, where there is a great need to detect disease priorMother-to-Child-Transmission of HIV and Syphilis globally.  According to seroconversionthe CDC website, "approximately 370,000 babies are born with HIV, mostly in sub-Saharan Africa. Without treatment, more than half of these children will die before the age of 2. Through key interventions, such as routinely testing pregnant women for HIV, providing antiretroviral medications to antibodies.  This would allow earlierHIV-infected pregnant women and their exposed infants, and promoting safe infant feeding practices, mother-to-child transmission of HIV can be decreased from about 35% to less than 5%.  Another prominent cause of infant mortality is untreated maternal syphilis, which still accounts for more than 500,000 stillbirths and infant deaths annually despite the fact that these deaths could be prevented through routine detection and treatment of diseases at an acute stage.  We have completed initial feasibility studies with technologies that complement our DPP® technology and that will further enable even lower limits of analyte detection, which is a capability we believe is essential to have in order to develop new products and markets over the long term.syphilis during antenatal care".
 
Regulatory Status of the DPP® HIV-Syphilis Test
 
DPP® HIV-Syphilis – We have developed this product for international and U.S. marketing. For the international market, the product has been registered in Mexico, and successfully launched and sold in this region.
In February 2015, this product was granted approval from the Brazilian ANVISA. We have submitted this product both for evaluation by the CDC, acting on behalf of the United States Agency of International Development, and the WHO, which has accepted this product to be evaluated for pre-qualification in its global procurement scheme. In October 2014, WHO conducted a three-day audit of our facilities as follow up to pre-qualification activities for the DPP HIV-Syphilis Assay, including other products submitted for pre-qualification through WHO.  No major non-conformances were identified during this audit, and we continue to work with WHO to obtain pre-qualification approval status for this device.

Our strategy with respectWe are developing a U.S. version of the DPP® HIV-Syphilis Assay, designed to our DPP® technology has evolved asmeet the Company has evolved.  Initially, followingperformance requirements for the issuance of our DPP® patent"reverse" algorithm that is currently in clinical use for syphilis testing in the United StatesStates.  We have completed our pre-clinical studies for this product with encouraging results, and are in 2007,the final stages of clinical site selection for our U.S. clinical studies.  We plan to begin this clinical trial in the U.S. during first quarter of 2016, and expect that the trial will be completed in six to nine months from initiation.
DPP® TECHNOLOGY & DEVELOPMENT
Chembio is executing its strategy was necessarily limited to developing third-party-funded OEM researchleverage the DPP® intellectual property and development contracts and grants.  This strategy enabled us to conserve capital resources, while at the same time acquiring know-how and experience with the platform and developing third party references and implicit endorsements of the technology.  As our capabilities to develop and manufacture DPP® products expanded, and as our financial position has improved, so have our strategic options expanded and improved.  While we may continue the strategy of seeking OEMproduct development and manufacturing agreementsexperience to create new collaborations where Chembio serves as a way to participate in markets that we cannot and/or choose not to serve, we believe that we can also develop our own branded linean exclusive development and manufacturing partner.  Examples of products, and we plan to do this insuch collaboration include the public health area.  This brand will be launched with our DPP® HIV Screening Assay in the United States market in 2013, to be followed by our Syphilis test and potentially other related productsfollowing:
 
Following is a discussion of the DPP® products for which we have completed our development activity pursuant to OEM agreements with FIOCRUZ and Bio-Rad Laboratories, Inc.  The statuses of products that are still under development are described in Part II Item 7.
 
The Company entered into an agreement to develop a POC diagnostic test for dengue fever virus, the DPP®  Dengue Fever Assay, which would be able to detect IgG/IGM and NS1 antigens in October 2014.
A collaboration also announced in October 2014, with an international diagnostics company to develop a POC diagnostic test for the early detection and monitoring of a specific type of cancer. At that time, the cancer project represented the first application of the DPP® technology outside the infectious disease field.
The Company entered into a follow-on, milestone-based development agreement with a private contracting organization acting on behalf of the United States Centers for Disease Control and Prevention (CDC), for a multiplex POC influenza immunity test utilizing Chembio's patented Dual Path Platform (DPP® ) technology.
In January 2015, Chembio entered into an agreement with the Concussion Science Group (CSG) Division of Perseus Science Group LLC, to utilize Chembio's patented DPP® technology to develop a POC diagnostic test for traumatic brain injury (TBI), including sports-related concussion. Under terms of the agreement, CSG's patented biomarker will be combined with Chembio's proprietary DPP® platform to develop a semi-quantitative or quantitative point-of-care test to diagnose TBI. CSG agreed to pay Chembio milestone development payments during 2015.
In January 2015, Chembio was awarded a grant from The Bill & Melinda Gates Foundation to expedite the feasibility testing and development of a DPP® Malaria POC rapid diagnostic to accurately identify individuals infected with Plasmodium falciparum parasite. Chembio's DPP® technology was selected for this grant due to its exceptional sensitivity and potential to aid the foundation in its goal of eradicating malaria. To achieve this goal, diagnostics must be capable of detecting the malaria parasite in infected, but asymptomatic, people. Current POC rapid diagnostics tests lack sufficient sensitivity to identify all individuals with transmissible infections.
In October 2015, Chembio was awarded a grant from the Paul G. Allen Foundation to develop a POC test to identify multiple life-threatening febrile illnesses. Under the $2.1 million dollar grant, Chembio will use its patented DPP® technology to develop a DPP® Fever Panel Assay, a POC multiplex assay to simultaneously detect Malaria, Dengue, Ebola, Lassa and Marburg.  The multiplex assay that is planned to be designed to include a quality control test band and seven tests bands with specific antibodies to detect different pathogens, including multiple serotypes of the same pathogen: Malaria PAN-PLDH antigen (Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, Plasmodium ovale), Malaria Falciparum HRP2 antigen, Ebola Virus PAN (Zaire, Sudan, Bundibugyo Virus), Marburg Virus, Lassa Virus, Dengue Virus (Dengue 1, Dengue 2, Dengue 3, Dengue 4) and Chikungunya Virus. In many parts of the world, these diseases are commonly misdiagnosed, resulting in a delay of treatment or failure to properly treat the underlying infection.  Misdiagnosis may be due to the fact that these diseases have similar symptoms that are difficult to distinguish.  Currently available POC diagnostics lack the ability to test for multiple diseases simultaneously. Further, existing POC diagnostics may lack the sensitivity and specificity required to detect infected but asymptomatic patients - information that is critical for preventing the spread of disease.
Also in October 2015, Chembio signed an agreement with opTricon (Berlin, Germany), a leading developer of mobile analysis devices for rapid diagnostic tests.  Through this exclusive agreement, subject to certain terms, and covering the fields of sexually transmitted diseases, certain "fever" diseases, and a specific form of cancer, Chembio will launch the DPP® Micro Reader, a point-of-care instrument designed specifically to complement Chembio's patented DPP® technology as applied to those diseases. The DPP® Micro Reader will include an innovative image sensor to provide a quantitative interpretation of diagnostic results when combined with Chembio's proprietary DPP® immunoassay technology.  Using a state-of-the-art camera system, the DPP® Micro Reader is designed to provide definitive diagnostic results for low analyte concentrations, which may otherwise result in faint or ambiguous test results.  In addition, the DPP® Micro Reader will provide customers with various options to capture, record, transmit and store test results. With one-button operation, the palm-sized and battery-operated DPP® Micro Reader is simple, fast, portable and cost-effective.

PARTNERS INVOLVED IN MARKETING OUR PRODUCTS
Alere
 
On September 29, 2006, we executed marketing and license agreements with Alere.  The marketing agreements (one for each of(the Barrel Agreement and the two FDA-approved products)Cassette Agreement) provide Alere with a 10-year exclusive right (until SeptemberMay 31, 2016) to market our rapid HIV tests in the United States under Alere’s brand.Alere's brands.  The agreements also provide Chembio a non-exclusive license to certain Alere lateral flow patents that may be applicable to our lateral flow products, principally including our lateral flowfor manufacture of the HIV tests that we have continued to marketin the United States for sales outside the United States.States and even for sale in the United States should Alere enter the U.S. market with a competitive rapid HIV test product and in such case we choose to market our products directly as provided in the agreements in such event of a competitive rapid HIV test product.  Simultaneous with the execution of the agreements, we also settled litigation with StatSure Diagnostics, Inc. (SDS), that had been ongoing relating to the proprietary barrel device which is incorporated into one of our two FDA-approved rapid HIV tests (See Lateral Flow HIV Tests above). SDS, pursuant to the settlement, is a party to the 3-way Barrel Agreement.  As a result, until now, it is through the agreements with Alere that we have been participating in the growth of the rapid HIV test market in the United States.
 
In late July 2013, we received notice from Alere that it intends to commercialize its own rapid HIV test (see Competition), which test had just received FDA approval as a moderate complexity product (i.e. not CLIA-waived though this was granted in late 2014), in the United States.  Under the Barrel Agreement and the Cassette Agreement such product is considered to be a Permitted Competing Product (PCP).  Each of the two aforementioned agreements provides that, in the case of notice of a PCP, Chembio may make certain elections (jointly with SDS in the case of the Barrel Agreement), or elect to continue each agreement without taking any further action.   Under the Cassette Agreement, Chembio may, at any time, terminate such agreement, which termination would become effective 60 days after the date notice was made. Under the Barrel Agreement, Chembio and SDS may jointly issue a non-exclusivity notice, which notice shall be effective immediately.  In the event that Chembio makes this election with respect to the cassette product, or that both Chembio and SDS make this election with respect to the cassette product, then the electing party or parties could sell that respective product in the United States market under its own brand, and in such case, the lateral flow license that Chembio has from Alere for international sales would be expanded to include sales in the United States.  See Lateral Flow Technology and Reagent Licenses.   In April 2014, the Company gave notice to Alere of its intent to terminate the Cassette Agreement and 60 days later, the Company began  marketing in the United States under the Chembio brand of HIV 1/2 STAT-PAK® assay.  The barrel product continues to be marketed exclusively by Alere in the U.S only, although on May 31, 2016, the Barrel Agreement will expire pursuant to its terms, and Chembio will also market the barrel product in the U.S. under the brand of SureCheck® HIV 1/2 Assay.
We have developed our own sales and marketing departments for the sales of our products in the U.S.  We have appointed distributors internationally for our lateral flow HIV tests.  Our largest markets outside the U.S. for our lateral flow HIV rapid tests are certain countries in Africa, Asia, and Asia,South America, as well as Mexico.  Internationally, most of the demand for our products is based on governmental and non-governmental prevention and treatment efforts.  Given this, these programs can and do often result in large orders, but also can result in periods of relatively lower demand, based on the variations associated with this kind of demand.
 
Our DPP® HIV test was approved by ANVISA in June 2010.  This approval was granted to our Brazilian partner, the Oswaldo Cruz Foundation (“FIOCRUZ”), pursuant to one of five technology transfer, supply and license agreements that we entered into with this public health organization in 2008 and 2010.  See “OEM DPP® Products,” below.

OEM DPP® Products
 
Oswaldo Cruz Foundation OEM DPP® Agreements
 
During 2008-2010 we signed five separate agreements, each of which is titled and constitutes a "Technology Transfer Agreement", with the Oswaldo Cruz Foundation (FIOCRUZ) in Brazil relatingBrazil.  FIOCRUZ includes the Institute of Technology on Immunobiologicals/Bio- Manguinhos, which is the FIOCRUZ unit that produces vaccines and diagnostic kits.  FIOCRUZ and Bio-Manguinhos are referred to herein interchangeably.  Each of the five agreements relates to a different specific product or group of products based on our DPP® technology.   FIOCRUZ is the leading public health organization in Brazil, and it is affiliated with Brazil’sBrazil's Ministry of Health, which is its principal client.  It has extensive research, educational and manufacturing facilities for drugs and vaccines, as well as for diagnostic products.
Each of the agreements grants to FIOCRUZ the right, but not the obligation, to earn the right to request a technology transfer to be able to license and manufacture that product on its own.  FIOCRUZ is not required to earn this right, but if it desires to do so, then it needs to purchase a stated amount of the product as set forth in the respective agreement for that product.
 
During 2010 and 2011, all of the initial products contemplated under the five agreements were approved for marketing by the applicable regulatory agencies in Brazil.  As a result, during 2011, we shipped approximately $4.25 million of products to FIOCRUZ pursuant to the agreements, and we expect that number to substantially exceed $9 million for fiscal year 2012.  The agreements between the Company and FIOCRUZ are unique examples of technology transfer collaborations between a private sector rapid test manufacturer and a public health organization.  The five products under agreement withcategories for which FIOCRUZ arecan earn a separate right to request a technology transfer for that product only are: DPP® products for HIV screening, HIV confirmatory,Confirmatory, Leishmaniasis, Leptospirosis and Syphilis.  All of the agreements with FIOCRUZ contemplate aEach technology transfer, and license to FIOCRUZ for the manufacture of the subject products over stipulated periods of time.  These technology transfers, and the provision by Chembio of the information and training that is required for this to occur, are subject towill occur only if FIOCRUZ purchases from Chembio receiving orders from FIOCRUZ for a minimumthe amount of products for manufacture by Chembio, whichthat product that is approximately $23 millionspecified in the aggregate under the five agreements.respective agreement for that product.  The actual demandamount of purchases for these productseach product is totally at the discretion and option of FIOCRUZ and may be more or less than this amount.  The actualthe amount will depend on the actual demand for the products by the specific programs for each product funded by the Brazilian Ministry of Health as well as whether and when FIOCRUZ is ableneeded to implement the technology transfer steps including, for example, the readiness of new production facilities currently under construction that are scheduled to be completed in mid-2013; thereafter Chembio may receive royalty payments under some of the agreementsqualify for a defined period based on product sold by FIOCRUZtechnology transfer.
More specifically, the five agreements, although separate and independent of one another, are structurally similar according to the public health programsfollowing:
Each agreement states: "the object of this Agreement is for the Transfer of Technology from Chembio to Bio-Manguinhos, the license by Chembio to Bio-Manguinhos for the Chembio Patents applied or granted in Brazil or other Mercosur countries for the term of the patents and the transfer of all the technical information related to the DPP® technology and the process to obtain the product by the DPP® technology.  This Agreement contemplates the scientific and technological co-operation between Chembio and Bio-Manguinhos for such activities so that Bio-Manguinhos will be able to manufacture the Product in Brazil."
Each agreement provides that Chembio will supply free of charge to Bio-Manguinhos prototypes of the product to demonstrate performance characteristics that are necessary for evaluation by the Brazilian Ministry of Health and for registration with ANVISA.  ANVISA is the Agencia Nacional de Vigilancia Sanitaria, or the National Sanitary Vigilance Agency.  The number of prototypes ranges from 15,000 to 45,000 in the various agreements.
Each agreement provides that the prototypes will be utilized both for a performance study that follows a protocol prepared and approved by Bio-Manguinhos and the Brazilian Ministry of Health, and also will be used for studies in Brazil for the registration procedures at ANVISA.  Bio-Manguinhos will then apply to ANVISA to register the product.  Within 120 days of the registration of the product with ANVISA, Bio-Manguinhos will make an advance technology transfer payment to Chembio (the "Advance Payment"), in an amount specified in that particular agreement.   All five of the Advance Payments provided for in the agreements were made in 2010 and 2011.
At such time, if any, that the product for a particular agreement has been successfully registered with ANVISA, then Bio-Manguinhos has the right to qualify for the full technology transfer for that product by purchasing the amount of the product, and at the price, specified in the agreement.
68

Bio-Manguinhos is not required to purchase any amount of any product.   For each product, it only needs to purchase that product, in the amount specified in the agreement, only if it desires to be able to complete the technology transfer process in order to manufacture and sell that product on its own.  Chembio does not have recourse against Bio-Manguinhos if Bio-Manguinhos does not purchase the qualifying purchase amount of any product.  In that case, Chembio can only suspend further phases of the technology transfer, attempt to renegotiate the agreement, and/or retain any amounts previously paid by Bio-Manguinhos.  Chembio cannot force Bio-Manguinhos to purchase any amount of any product.
As a result of the terms of these agreements, Bio-Manguinhos has never been required to, and is not now required to, purchase any amount of any of the products.
As of December 31, 2015 Bio-Manguinhos had earned the status described below with respect to each of the five products:
1.
With respect to Chembio's DPP® HIV1/2 Screen test, Bio-Manguinhos had qualified to request the technology transfer.  It has requested, and has received, the technology transfer information.  Bio-Manguinhos purchased $880,175, $4,990,840 and $291,235 of this product in 2011, 2012 and 2013, respectively, all of which applied to the qualifying amount to obtain the right to the technology transfer (the "Qualifying Amount") for this product.  In 2013, 2014 and 2015, Bio-Manguinhos made $3,320,010, $4,799,250 and $5,410,350, respectively, of purchases in excess of the Qualifying Amount.
2.
With respect to Chembio's Canine Leishmania test, Bio-Manguinhos had qualified to request the technology transfer and did so request.  Submission of the technology transfer information is in process at this time.  Bio-Manguinhos purchased $2,000,817 and $99,183 of this product in 2011 and 2012 respectively, of this product in that applied to the Qualifying Amount.  In addition, Bio-Manguinhos made purchases in excess of the Qualifying Amount equal to $1,314,117, $1,736,700, $2,394,000 and $3,772,482 in 2012, 2013, 2014 and 2015, respectively.
3.
a.
With respect to the three variations of Chembio's DPP® Syphilis test, all of which are covered by a single agreement, Bio-Manguinhos had qualified to request the technology transfer with respect to Trep only, and intends to do so in the near future.  Bio-Manguinhos purchased $1,194,250, $165,750 of this product in 2011 and 2012, respectively that applied to the Qualifying Amount.  In addition, Bio-Manguinhos made purchases in excess of the Qualifying Amount equal to $2,817,750, $646,340, $4,617,891 and $833,631 in 2012, 2013, 2014 and 2015, respectively.
b.
With respect to the two variations of Chembio's Screen & Confirm Test, Bio-Manguinhos had not made any purchases in 2011, 2012, 2013, 2014 or 2015, and therefore had not qualified to request the technology transfer for either of them.  This agreement was terminated in December 2015.
c.
This syphilis agreement was terminated during the fourth quarter of 2015.

Bio-Rad Laboratories
4.
With respect to Chembio's DPP® Confirmatory test, Bio-Manguinhos had not qualified to request the technology transfer.  Bio-Manguinhos made purchases of $560,000, $819,000, $390,000, $390,000 and $156,000 of this product in 2011, 2012, 2013, 2014 and 2015 respectively, all of which applied to the Qualifying Amount.  In order to qualify for the technology transfer, Bio-Manguinhos would need to purchase an additional $39,000 of this product.
5.
With respect to Chembio's DPP® Leptospirosis test, Bio-Manguinhos had not qualified to request the technology transfer.  Bio-Manguinhos made purchases of $135,000 of this product in 2011, and it made -0- purchases in 2012, $45,000 in 2013 and it made -0- purchases in 2014 and -0- in 2015.  In order to qualify for the technology transfer, Bio-Manguinhos would need to purchase an additional $225,000 of this product.
As stated above, Bio-Manguinhos is not obligated to make any purchases.  After the specified level of sales for a particular product has been achieved, FIOCRUZ may request that the technology for that product be transferred to FIOCRUZ together with an exclusive license to produce and sell that product in a defined territory.  The license is to provide that Chembio will receive a royalty on all sales.  Chembio does not release the amount of this royalty because it could have an adverse effect on negotiations concerning royalties in potential transactions with other parties.
All the agreements expire five years after the date of the technology transfer.  If terminated earlier by default of FIOCRUZ, FIOCRUZ must stop all activity; if terminated earlier by default of Chembio, or if terminated by natural expiry, FIOCRUZ can continue to produce and commercialize the product without paying royalties.
Other OEM And License Agreements Related to DPP® Agreement- On April 6,Technology
In addition to our agreements with FIOCRUZ, we have entered into certain OEM and license agreements with other parties with respect to certain products that we have developed based on our DPP® technology.  In 2008 we entered into a milestone-basedproduct development and license agreement with Bio-Rad Laboratories, N.A., a division of Bio-Rad Laboratories Inc. (NYSE:BIO)(Bio-Rad), a leading in-vitro diagnostic andmultinational life science company.  The agreement with Bio-Rad wassciences company, for the developmentfirst ever POC test for the confirmation of a six-band multiplexHIV (reflex test used after initial screening test(s) are positive).  This product onutilizes our DPP®.  Based technology, capitalizing on achievingits multiplexing advantages, and is much simpler to perform than the prooflegacy confirmatory platform, known as western blot, which requires a substantial amount of concept for thistechnical training and hands-on time and which is more expensive to manufacture and distribute.  This product during 2008, in January 2009 we entered a limited exclusive license agreement withwas CE marked and was launched by Bio-Rad related to the field of use for this application, and we continued the development work during all of 2009 and until Bio-Rad confirmed that the product specifications were met in the second quarter of 2010.  2013 in Europe under their Geenius® brand; and an FDA PMA approval was received in 2014.
In June 2010, Bio-Rad exercised its option2013 we entered into collaboration with Labtest, a private company in Brazil, for the distribution of a number of products in Brazil that would be co-branded with Labtest and Chembio trademarks.  Under this agreement, upon request from Labtest, for which there is no requirement, Chembio will sell the appropriate DPP® components to haveLabtest for further manufacture and assembly in Brazil.
In February 2014, Chembio entered into a technology transfer the manufacturing of this product to Bio-Rad subject to a royalty payment payable to Chembio pursuant to aand license agreement with Bio-Rad basedRVR Diagnostics SDN BHD ("RVR"), a privately-held company in Malaysia. The agreement supports Chembio's strategy of establishing a market presence in Asia, in collaboration with RVR as a licensee, distributor, and contract manufacturer, depending on Bio-Rad’s net sales of the licensed product, which process was completedcircumstances. The agreements grant exclusive distribution rights to RVR in October 2010.certain countries in the region and enable RVR to manufacture Chembio's DPP® HIV 1/2 Assay and DPP® HIV-Syphilis Assay, and potentially other products developed by Chembio, believes that Bio-Rad is proceeding withsuch as Dengue, incorporating its patented DPP® technology as indicated in the regulatory approvals of this product, with CE Mark likely by the end of 2012 or early 2013, although there can be no assurance of this.  We further believe that Bio-Rad has begun discussions with the FDA with respect to this product, its proposed performance claims and the intended clinical protocol to support its regulatory submission.
During 2008 to 2010, Chembio earned approximately $460,000 for product development work rendered to Bio-Rad under this agreement, plus an additional $490,000 in license and other fees related to the manufacturing transfer.DPP® Technology & Development section above.
 
Our Rapid Test Technologies
 
All of our commercially available current products employ either in-licensed lateral flow technology or our own patented Dual Path Platform®Platform (DPP®) technology and are visually read.  We can also use handheld and desktop readers with our DPP® products to objectively measure, quantify, record and report DPP® test results.  Certain of the products we have and/or are developing incorporate some of these readers, and we are developing other products that may be used with or will require use of a reader.
technology. Both lateral flow technology and DPP® allow the development of accurate, low cost, easy-to-perform, single-use diagnostic tests for rapid, visual detection of specific antigen-antibody complexes on a test strip.  These formats provide a test that is simple (requires neither electricity nor expensive equipment for test execution or reading, nor skilled personnel for test interpretation), rapid (turnaround time approximately 15 minutes), safe (minimizes handling of potentially infected specimens), non-invasive (requires 5-20 micro liters of whole blood easily obtained with a finger prick, or alternatively, serum or plasma,)plasma), stable (24 months at room temperature storage in the case of our HIV tests), and highly reproducible.

We believe that products developed using DPP® technology can provide superior diagnostic performance as compared with products that use lateral flow technology.  The reason for this is that one of the major differences between the two platforms is that in DPP® samples are allowed to incubate with the target analyte in the test zone before introduction of the labeling reagent/conjugate, whereas in lateral flow, samples are combined with the labeling reagent to form a complex before coming in contact with the target analyte.  We believe that this complex can compromise test performance.  Also, because of the usage in DPP® of a separately connected sample strip, the control and delivery of sample material is substantially improved.  This feature is critical in the development of multiplex tests, as well as tests that involve viscous sample material (such as oral fluid) that can be impeded when forced to combine with labeling reagents before migration on the test strip to the test zone area.
 
Multiplexing is significantly improved as a result of the design of DPP® and this provides a significant advantage.  TheFor example, the HIV confirmatory test we developed for Bio-Rad that is described above employs six different markers.markers related to various epitopes of the HIV antigen.  We have a contractnumber of other products in development, programincluding those being developed in sponsored development programs that involved the use of eight bands.  Our intellectual property also extends toinvolve the use of multiple (e.g. eight) test membranes that through a common sample strip utilize a single sample.  Employing this featurebands. Although all of these products could be visually read, we can develop so-called “Fourth Generation” testsalso use handheld and desktop readers with our DPP® products to objectively measure, quantify, record and report DPP® test results.  Certain of the products we have and/or are developing incorporate some of these readers, and we are developing other products that may be used with or will require use of a reader.  Also, platforms can incorporate labeling reagents that cannot be visually read except by employing a reader, such as fluorescence, though no products are able to detect antigens prior to seroconversion to antibodies, as well as antibodies.  This would allow earlier detection of diseases at an acute stage, which improves outcomes.currently utilizing such reagents.
  We have completed initial feasibility studies withare pursuing additional capabilities and technologies that uniquelywill complement our DPP® technologycurrent product portfolio and business strategy.  This activity includes pursing development, license or acquisition of diagnostic technologies that will assistcomplement our existing platforms, proprietary biomarkers that can result in these efforts by enabling even lower limitsnew product applications of analyte detection.  This is a capability which we believe is essential to have in order to developour existing platforms, and new products and markets over the long term.platforms that would complement our commercial strategy.

Target Markets
 
Rapid HIV Tests
 
A large percentage of individuals that are HIV positive worldwide are unaware of their status.  Part of the reason for this is that even those that do get tested in public health settings will often not return or call back for their test results ifwhen samples have to be sent out to a laboratory which can take at leastup to several days to process.  However, theThe increased availability, greater efficacy and reduced costs for anti-retroviral treatments (ARVs) for HIV has increased the demand for testing, as the stigma associated with the disease is lessened, and the ability to resume normal activities is substantially improved, providing a positive message to those potentially infected.  The impact that rapid HIV testing has had on prevention efforts has in turn increased the demand for testing, particularly by public health programs worldwide, which have also become more effective in reducing the number of annual new infections in many, but by no means all, high prevalence regions.
 
ThereDespite less attention to HIV by the media as compared with prior years, there are still approximately 53,00050,000 new diagnoses of HIV infection in the United States each year, according to the CDC.  In time, most of these infections progress to AIDS.  The CDC estimates that approximately 1.1 million individuals in the U.S. are living with HIV, with an estimated 250,000 Americans,1 of 8 of these U.S. individuals, or more than 20%almost 13%, unaware that they are infected.  It is transmissions from these 250,000 infected people that are reported to account for 54%the majority of all new infections per year.  Part of the reason for this is that even those individuals that do get tested in public health settings will often not return or call back for their test results fromif their blood samples that  have to be sent out to and tested in a laboratory and thatthen reported back,  a process which can take at leastup to several days to process.complete.  Making more people aware of their HIV status at the point-of-care will reducereduces the number of HIV transmissions.
 
Rapid HIV testing in the United States has now developed into an estimated 77.5 million test market.  This is from zero in 2003 when Orasure Technologies, Inc. received the first FDA approval for a rapid HIV test.  We believe that the US professional HIV rapid test market (not including the OTC market) has the potential to increase to 15-18 million tests over the next several years, which would represent 40-50% of all HIV tests done today in the United States for clinical purposes.  Assumingat an average price to the manufacturers of $8.00 per test,$10, or a total potential U.S.of $75 million. Public health programs, currently funded by grants distributed to states by the CDC, account for an estimated 45% of the market, with hospitals (40%) and doctor's offices (15%) comprising the other estimated market segments.  Chembio's rapid HIV tests represent approximately a 20% share of nearly $120-$150 million is implied.this market.  OraSure Technologies, Inc., which was the first FDA-approved rapid HIV test, maintains approximately 50% of this market.  Trinity Biotech has an estimated 15% market share and Alere, Biolytical Laboratories, Medmira and Bio-Rad share the remaining 10%.

In 2006, the outlook for HIV testing was given a big boost with the release by the CDC of new guidelinesrecommendations for HIV testing. These new CDC recommendations were/are that an HIV test should be given as a routine test like any other for all patients between 13 and 64 years of age, regardless of risk, with an opt-out screening option and focused testing procedural (pre- and post-test counseling) guidelines.  AdoptionThough not mandatory, gradual adoption in whole or in part of the 2006 CDC recommendations by a number of states continues to have an increasing impact.  Most recently,Finally, in 2013, the United States Preventive Services Task Force (“USPSTF”("USPSTF") fully embraced these CDC routine HIV testing recommendations of the CDC’s after years of still endorsing the older CDC recommendation of a risk-based approach.recommendations.  This USPSTF policy will mandaterecommendation, which was given an A grade under their recommendation grading system based on the benefits of this practice and the nearly 600,000 AIDS-related deaths in the United States,  requires  insurance coverage under the Affordable Care Act (the “ACA”"ACA") and weas a preventive screening test without any co-payment required. We expect this to result in an increase in HIV testing in the United States in the coming years.  Currentlyyears, which we believe will include point-of-care HIV testing utilizing the Company's products.  Although as stated above, currently most public health testing in the United States is funded by grants allocated to high prevalence areas by the CDC, but we believe this will shift to an insurance-funded model under the ACA in the years to come.come, increasing the amount of testing done in doctor's offices and community health centers.
 
In the international market, PEPFAR, thewe sell our products directly and through distributors to large United Statesscreening programs overseen by ministries of health and NGOs, most but not all of which are funded internationalby large bi-lateral and multi-lateral AIDS relief programs, the largest of which is the U.S. President's Emergency Plan for AIDS Relief (PEPFAR).  Established by President George Bush as a 5-year $15 billion program focused on fifteen countries,in 2003, PEPFAR was reauthorized in 2008 and again in 2013.  In 2012 PEPFAR directly supported HIV testing and counseling for upmore than 11 million pregnant women, and testing and counseling for more than 49 million people overall. The U.S. is also the first and largest donor to $48 billion for FY2009-2013 (up from $15 billion in 2004-2008).  PEPFAR and the Global Fund areto Fight AIDS, Tuberculosis and Malaria. To date, the largest ofU.S. has provided more than $7 billion to the global initiatives that have helped to make prevention, care and life-saving treatments available to those that need them.  For example, PEPFAR has the goal that by 2013 three million infected individuals will be provided treatment and 12 million new cases will be averted.  To achieve these goals, more and more people are likely to get tested.  As more effective treatments become available at lower costs, there is a clearer reason to be tested.Fund.
 
The U.S.In December 2013 President Obama signed into law the PEPFAR Stewardship and international economics crisisOversight Act, which is the most recent reauthorization of PEPFAR. However, unlike the last few years has impacted2008 PEPFAR authorization, which authorized approximately $45 billion, the growth in fundingnew law doesn't authorize a specific dollar amount for funding.  Nevertheless it is widely anticipated that PEPFAR will continue to enjoy strong funding; the FY14 budget had $6 billion for global HIV/AIDS assistance, including $4 billion for PEPFAR.
Chembio, with its four U.S.-manufactured rapid HIV tests, all of these large programs, though private donations have supplemented the governmental and non-governmental programs.  Still, accountability, alleged corruption, and the eligibility of lower quality and lower cost products make these markets challenging.  Regardless of these occurrences, we believe that Chembio has remained, andwhich are FDA-approved, is increasingly recognized as a reputable and dependable supplier of high quality products that are available at reasonably competitive prices.  As a result, certain of our products have been selected in the testing protocols in countries (national algorithms) that are large beneficiaries of PEPFAR and the Global Fund. As mentioned above, these programs can and do often result in large orders, but also can result in periods of relatively lower demand, based on the variations associated with this kind of demand.  Also, even though the United States taxpayer is funding the largest share of global AIDS relief, U.S. companies do not receive any preference for these procurements, and therefore must compete with foreign suppliers that manufacture competitive products with lower costs, including those related to quality, regulatory, intellectual property, and costs of manufacturing.
 
Oral fluid testing is an established alternative to blood testing for diagnostic tests, including HIV tests.  It is also often patient preferred, providing a more comfortable, less invasive test.  In certain public health clinics, staffs choose not to handle blood specimens; thus, oral sample collection provides a viable alternative.  The most well-established market for oral fluid HIV testing is the United States.  Given the premium price required for an oral fluid test as compared with blood tests, the higher volume programs will not specify an oral fluid test.  However, segments of these programs may want to have an oral fluid testing option, and certain programs that have greater resources may also choose to incorporate oral fluid testing into the testing protocol.

There is also now an over-the-counter market for HIV self-testing and we are well positioned to participate in this market, should we believe the investment is justified.  So far one company, OrasureUnited States.  OraSure Technologies Inc., received FDA approval for an over-the-counter (self-testing) version of its previously professional-market-approved (test performed on an individual by a health care professional) HIV test.  The FDA approval was granted in July 2012, the product was launchedand OraSure has been investing heavily in October, and we believe that the results during the first several months of 2013 will be instructive as to how rapidly this market can develop.
Based on the fact that FDA has required any over-the-counter HIV test to have first been approved for the professional market, we believe that Chembio is the only other company that can participate in this market opportunity if it chooses to.  Although there is a third company, Trinity Biotech, that meets that condition, they have stated that they do not intend to pursuedeveloping this market. Therefore Chembio is carefully monitoring developments in this market, which may be significant during 2013.  Currently we could initiate the over-the-counter approval process with eitherInitial results after over two years of our two blood tests.  And we have nearly completed a preliminary self-study for one of those products as the final component to our submitting an Investigational Device Exemption (“IDE”) application to the FDA during the first quarter of 2013.  Provided we submit this application and it is granted, that would enable us to begin clinical trials by the time we gather better information as to how the Orasure product is doing in the market.  And now that we have received approval of our pre-marketing application for our DPP® oral fluid HIV test, we could additionally, or alternatively, pursue over-the-counter approval for that product once we receive the CLIA waiver grant for that product.  We believe that wemarketing are well advised to wait before commencing these clinical trials because (1) thebelow expectations.  The costs for such over-the-counter approval, including primarily the associated clinical trials, are estimated to be at least $5 million and they may take two to three years to complete; (2) Orasure’s first six monthscomplete, not to mention the cost of distribution.  OraSure's initial results will be known relatively soon; and (3)are not convincing of a large market, although this possibility remains.  If it appears that there is an attractive market, we believe we are very well positioned versus any other competitors.to participate in this market.

Rapid Syphilis TestsHIV-Syphilis Test
 
Recent data indicate that approximately 70,000-100,000 new casesThere are significant risks relating to transmission of syphilisSyphilis from a pregnant mother to child, just as there are occurring annually in the U.S. Syphilis can be treated with antibiotics, but untreated it can cause pelvic inflammatory disease, infertility, ectopic pregnancy and can infect newborns.  Treatment cannot be provided without a confirmed diagnosisfor transmission of an active case of syphilis.  Current testing algorithms in the United States require two different tests (called non-treponemal and treponemal markers), each requiring trained personnel in laboratory settings and several days to receive back results, in order to confirm an active, previously untreated case.  The screening test still employed in the United States is known as RPR; it utilizes an old technology that has a high degree of false positive results.
Development of the POC market for syphilis testing is expected to be comparable to the development of the POC market for HIV testing, asHIV.  Therefore we believe there is a significant public health valueopportunity to being ableimprove prevention efforts in pregnant mother to provide results at the point-of-care.  Therechild transmission testing programs (PMTCT) that are several ways to assess the market opportunitycurrently not doing any or nearly enough testing for this unique rapid test, although we believe the U.S. rapid test market opportunity may exceed 8 million tests, which is approximately 20% of the total number of syphilis tests performed ineven though they are testing for HIV.  In the United States, we believe there is also a significant need for clinical use today.  Unlikethis product in some of the highest HIV testing, where a positive result first requires a confirmatory test,prevalence populations, such as among men that have sex with men (MSM), as data show high degrees of HIV and then further tests to measure viral load before expensive treatment decisions are made, an individual with a confirmed active caseSyphilis co-infection in this segment of syphilis can be prescribed antibiotics immediately.the population.

Marketing Strategy
 
Our marketing strategy is to:
 
·  
Support,
Market our DPP® HIV 1/2 Assay, HIV 1/2 STAT-PAK® Assay and future DPP® based new products in the US through our internal sales and marketing organization and selected channel partners (e.g., McKesson/PSS, Fisher Healthcare, Henry Schein, etc.).  Chembio, following the June 2014 termination of the STAT-PAK® agreement with Alere, does not have to share any portion of the net sales proceeds for STAT-PAK® with Alere.  This decision resulted in incurring expenditures related to hiring sales representatives, establishing agreements and associated discounts with distributors, incurring advertising and marketing expenditures, warehousing, customer service and technical support. If Alere's new competitive product is indeed successful, our ability to retain a significant share of the market that has been established for our products may be enhanced by our having control of the marketing of our products, rather than relying on Alere to sell both our products while it is also selling its own competing product. We are leveraging the same sales force for U.S. Sales of DPP® HIV 1/2 Assay.
We will support, review and assess the marketing and distribution efforts of our rapid HIV tests by Alere.  Alere, which is a leading marketer of point-of-care diagnostic products, has significantly expanded its distribution footprint sincebarrel test in the U.S.
Outside the U.S., we signed our agreement with them, and although we believe that this will enhance opportunities for Alere to market our rapid HIV tests, the product line is a very small one for them, notwithstanding the strong growth they have enjoyed with respect to our products.products primarily through commercial collaborators and distribution partners.
·  
Leverage our DPP® intellectual property and regulated product development and manufacturing experience to continue creating new collaborations where Chembio can be the exclusive development and manufacturing partner supporting leading marketing organizations.
·  
Establish strong distribution relationships for our Chembio-branded products in the U.S and abroad, and establish a direct sales and marketing organization that is focused in the public health market segment, and that utilizes distributors for other market segments, primarily the acute care market which, together with public health, are the main market segments for rapid HIV tests in the United States.  We believe that creation of a Chembio public health brand and marketing organization is fundamental to long-termthe creation of shareholder value.value over the long-term.
We have increased our commercial activities and efforts in Africa, Europe and Asia for our HIV tests and product pipeline.  We believe these efforts will enable us to be more closely engaged with opportunities to engage with customers and partners and to participate in the national testing algorithms that are established and revised from time to time by countries that are beneficiaries of PEPFAR, Global Fund and/or other bilateral or multilateral donor funding.  In Europe, where there are a larger percentage of HIV positive people unaware of their status than in the United States, we believe that there is an emerging public health outreach opportunity, and there are relatively few strong competitors that are CE-marked.  Most recently we have established new sales and marketing positions in the Company to support our efforts to increase brand awareness globally and to lead our direct sales effort in the U.S. market.

Competition
 
The diagnostics industry is a multi-billion dollar international industry and is intensely competitive.  Many of our competitors are substantially larger and have greater financial, research, manufacturing and marketing resources.
Industry competition in general is based on the following:
 
·  
Scientific and technological capability;
Proprietary know-how;
·  
Proprietary know-how;
·  The ability to develop and market products and processes;
·  
The ability to obtain FDA or other required regulatory approvals;
·  
The ability to manufacture products that meet applicable FDA requirements, (i.e. FDA’sFDA's Quality System Regulations) (see Governmental Regulation section);
·  
The ability to manufacture products cost-effectively;
·  
Access to adequate capital;
·  
The ability to attract and retain qualified personnel; and
·  
The availability of patent protection.
We believe our scientific and technological capabilities and our proprietary know-how relating to our in-licensed lateral flow technology rapid tests and to our proprietary know-how related to our patented dual path platform®DPP® technology, particularly for the development and manufacture of tests for the detection of antibodies to infectious diseases such as HIV, are very strong.
 
10

Our ability to develop and market other products is in large measure dependent on our having additional resources and/or collaborative relationships.  Some of our product development efforts have been funded on a project or milestone basis.  We believe that our proprietary know-how in lateral flow technology and in our Dual Path Platform® (DPP®)DPP® technology has been instrumental in our obtaining the collaborations we have and that we continue to pursue.  We believe that the patent protection that we have with our Dual Path Platform® (DPP®)DPP® technology enhances our ability to develop more profitable collaborative relationships and to license out the technology.  However there are a number of competitive technologies used and/or seeking to be used in point-of-care settings.  These technologies may be based on immunoassay principles such as the Company’sCompany's products or other technologies, such as molecular-based technologies.
 
We launched our FDA-approved DPP® HIV 1/2 Assay, which test also can be used with either oral fluid or blood samples, in the U.S. market under a Chembio brand in the fourth quarter of 2014.  OraSure Technologies manufactures the only other rapid, oral fluid HIV test that is FDA-approved, and OraSure has enjoyed this position for approximately 10 years.  OraSure has lost a significant share of this market as certain customers have been indifferent to using blood or oral fluid samples, because the blood tests, including those made/marketed by Chembio and marketed by Alere, are priced lower and/or are as or more accurate than the performance of OraSure's product on blood samples.  OraSure has primarily retained those customers for whom the oral fluid sample feature is a strong preference, and this is an estimated $35 million business for OraSure.  Although we believe we can capture a meaningful portion of this OraSure market share, we also anticipate that OraSure will defend this business aggressively.
In 2006 Alere acquired a division from Abbott Diagnostic located in Japan that manufactured and marketed a rapid HIV test product line called Determine®.  The Determine® format was developed for the developing world and remote settings and, central to the needs of that market, the format is essentially a test strip that is integrated  into a thin foil wrapper that, when opened, the underside of the wrapper serves as the test surface for applying the blood sample and performing the test.  This design reduces costs and shipping weights and volumes and is an advantage for the developing world markets it has served.  Some of the disadvantages of the platform are the amount of blood sample that is needed (50 microliters versus 2.5, 5 and 10 for our lateral flow barrel, lateral flow cassette, and DPP® products respectively),  the open nature of the test surface, and the absence of a true control that differentiates biological from other kinds of samples.
The so-called "3rd generation" version of this product has been marketed for many years and is the leading rapid HIV test that is used in a large majority of the national algorithms of countries funded by PEPFAR and the Global Fund, as well as many other countries in the world.  That product is not FDA-approved though it is CE-marked. The newest Determine® HIV version, which was developed and manufactured at Alere's subsidiary in Israel, Orgenics, is the so-called "4th Generation" version Determine® test. According to its claims, this product detects HIV antibodies and P24 HIV antigens. Since the P24 antigen is known to occur in HIV-positive individuals' blood samples before antibodies do, based on its performance claims, the 4th generation Determine® test is  therefore able to detect HIV infection earlier than tests that solely rely on antibody detection. Chembio's tests, as well as all of the other currently FDA-approved rapid HIV tests, only detect antibodies.  There are however laboratory tests that are FDA-approved that are "4th generation" tests, but they are of course neither rapid nor point-of-care.
The initial "4th generation" Alere Determine® rapid test product that was also CE-marked and that Alere launched internationally some years ago has not been successfully commercialized to the best of our knowledge and at  least certain published studies were not favorable for this product.  However the 4th generation product that is now FDA-approved was apparently modified as compared to the initial international version of it, and it may perform more satisfactorily.  Alere received FDA approval of this modified product in August 2013 and CLIA-waiver for it in the fourth quarter of 2014.  There is support by a number of key opinion leaders for the public health value of such 4th generation tests, and it represents a significant competitive threat to Chembio as well as to each of the other rapid HIV test manufacturers (OraSure and Trinity primarily).
During 2011 Biolytical, Inc. of Vancouver, Canada received FDA approval and in 2012 received CLIA waiver of a flow-through rapid HIV test called "INSTI".  The technology used in the INSTI test, flow-through, is older than lateral flow, and it requires handling of multiple components (3 vials of solution) to perform the test in multiple steps.  However, these steps can be accomplished in less than ten minutes, and the actual test results occur in only one minute after those steps are completed.  Therefore sample-to-result time is shorter than any of the competitive products.  There are settings where that reduced total test time, despite the multiple steps required, may be a distinct advantage, and we believe Biolytical has made some progress in penetrating certain public health markets.
Although we have no specific knowledge of any other competitors' products that are a competitive threat to our products, or that will render our products obsolete, if we fail to maintain and enhance our competitive position or fail to introduce new products and product features, our customers may decide to use the products developed by our competitors, which could result in a loss of revenues and cash flow.
Research and Development
 
During 20112015 and 2010, $4.92014, we spent $6.40 million and $4.1$4.80 million, ($2.6 million, net of Qualified Therapeutic Discovery Project (“QTDP”) grants), respectively, were spent on research and development (including regulatory activities).  These expenses were in part underwritten by funding from R&D and milestones revenues of $1.8$2.30 million in 20112015 and $2.8$1.70 million in 2010.2014.  All of our new product development activities involve employment of our Dual Path Platform® (DPP®)DPP® technology.  These activities include completing development of certain products and making significant progress toward the development of additional products.
 
Employees
 
At September 30, 2012,December 31, 2015, we employed 172approximately 155 people.  We have entered into employment contracts with our Chief Executive Officer and President, Lawrence Siebert,John J. Sperzel, our Chief Operating Officer, Sharon Klugewicz, and our Senior Vice President of ResearchChief Science and Development,Technology Officer, Javan Esfandiari.  Due to the specific knowledge and experience of these executives regarding the industry, technology and market, the loss of the services of eitherany one of them would likely have a material adverse effect on the Company.   The contract with Ms. Klugewicz, has a term of two years ending May 2017.  The contract with Mr. SiebertEsfandiari has a term of three years ending March 2019.  We have obtained a key man insurance policy for Mr. Esfandiari.  The contract with Mr. Sperzel provides that Mr. SiebertSperzel will serve as the Chief Executive Officer and President of the Company through May 11, 2013.  The contract with Mr. Esfandiari has a term of three years ending March 2013.  We have obtained a key man insurance policy for Mr. Esfandiari.2017.

Governmental Regulation
 
The manufacturing and marketing of the Company’sCompany's existing and proposed diagnostic products are regulated by the United States Food and Drug Administration (“FDA”("FDA"), United States Department of Agriculture (“USDA”("USDA"), certain state and local agencies, and/or comparable regulatory bodies in other countries.  These regulations govern almost all aspects of development, production and marketing, including product testing, authorizations to market, labeling, promotion, manufacturing and record keeping.  The Company’sCompany's FDA and USDA regulated products require some form of action by each agency before they can be marketed in the United States, and, after approval or clearance, the Company must continue to comply with other FDA requirements applicable to marketed products, e.g. Quality Systems (for medical devices).  Failure to comply with the FDA’sFDA's requirements can lead to significant penalties, both before and after approval or clearance.
 
There are two review procedures by which medical devices can receive FDA clearance or approval.  Some products may qualify for clearance under Section 510(k) of the Federal Food, Drug and Cosmetic Act, in which the manufacturer provides a pre-market notification that it intends to begin marketing the product, and shows that the product is substantially equivalent to another legally marketed product (i.e., that it has the same intended use and is as safe and effective as a legally marketed device and does not raise different questions of safety and effectiveness).  In some cases, the submission must include data from human clinical studies.  Marketing may commence when the FDA issues a clearance letter finding such substantial equivalence.  FDA clearance of our DPP® Syphilis Screen & Confirm test will be by means of a 510(k) submission.
 
If the medical device does not qualify for the 510(k) procedure (either because it is not substantially equivalent to a legally marketed device or because it is required by statute and the FDA’sFDA's implementing regulations have an approved application), the FDA must approve a Pre-Marketing Application (“PMA”("PMA") before marketing can begin.  PMA’sPMA's must demonstrate, among other matters, that the medical device provides a reasonable assurance of safety and effectiveness.  A PMA application is typically a complex submission, including the results of non-clinical and clinical studies.  Preparing a PMA application is a much more expensive, detailed and time-consuming process as compared with a 510(K) pre-market notification.  The Company has approved PMAs for the two rapid HIV tests now marketed in the U.S.: both our HIV 1/2 STAT-PAK® and also our test that currently is marketed in the U.S. by Alere Medical as Clearview® Complete HIV 1-21/2 and Clearview® HIV 1-21/2 STAT PAK®.
 
11

FDA approval of our DPP® HIV screening assay for use with oral fluid or blood samples also was achieved by means of a PMA application.  The Clinical Laboratory Improvement Act of 1988 (“CLIA”("CLIA") prohibits laboratories from performing in-vitro tests for the purpose of providing information for the diagnosis, prevention or treatment of any disease or impairment of, or the assessment of, the health of human beings unless there is in effect for such laboratories a certificate issued by the United States Department of Health and Human Services (via the FDA) applicable to the category of examination or procedure performed.  Although a certificate is not required for the Company, it considers the applicability of the requirements of CLIA in the design and development of its products.  The statutory definition of “laboratory”"laboratory" is very broad, and many of our customers are considered labs.  A CLIA waiver will remove certain quality control and other requirements that must be met for certain customers to use the Company’sCompany's products and this is critical to the marketability of a product into the point-of-care diagnostics market.  The Company has received a CLIA waiver for each of the two lateral flow rapid HIV tests now marketed by Alere Medical as Clearview® Complete HIV 1/2 and Clearview® HIV 1/2 STAT PAK®.in the U.S.  The CLIA waiver was granted by the FDA for HIV 1/2 STAT-PAKSTAT-PAK® on November 20, 2006 and for the Clearview® Complete HIV 1/2 on October 22, 2007.  In 2008 the FDA revised its CLIA waiver requirements so that an additional prospective trial need be conducted in order to demonstrate clinical utility by showing that the device is capable of identifying new infections.  Given the low prevalenceinfections when used by untrained users.  Our DPP® HIV 1/2 test received CLIA waiver in October of HIV, the FDA will require 30 new HIV cases to be identified, supplemented by additional data and this is the study the Company will perform during 2013.2014.
 
In addition, the FDA regulates the export of medical devices that have not been approved for marketing in the United States.  The Federal Food, Drug and Cosmetic Act contains general requirements for any medical device that may not be sold in the United States and is intended for export.  Specifically, a medical device intended for export is not deemed to be adulterated or misbranded if the product: (1) complies with the specifications of the foreign purchaser; (2) is not in conflict with the laws of the country to which it is intended for export; (3) is prominently labeled on the outside of the shipping package that it is intended for export; and (4) is not sold or offered for sale in the United States.  However, the Federal Food, Drug and Cosmetic Act does permit the export of devices to any country in the world, if the device complies with the laws of the importing country and has valid marketing authorization in one of several “listed”"listed" countries under the theory that these listed countries have sophisticated mechanisms for the review of medical devices for safety and effectiveness.
 
15

The Company is also subject to regulations in foreign countries governing products, human clinical trials and marketing, and may need to obtain approval or evaluations by international public health agencies, such as the World Health Organization, in order to sell diagnostic products in certain countries.  Approval processes vary from country to country, and the length of time required for approval or to obtain other clearances may in some cases be longer than that required for United States governmental approvals.  On the other hand, the fact that our HIV diagnostic tests are of value in the AIDS epidemic may lead to some government process being expedited.  The extent of potentially adverse governmental regulation affecting Chembio that might arise from future legislative or administrative action cannot be predicted.
 
One or more of the Company’s rapid HIV tests are also approved or pending approval for marketing in several foreign jurisdictions, including but not limited to Brazil, Mexico, and a number of other nations in the developing world.
Environmental Laws
 
To date, we have not encountered any costs relating to compliance with any environmental laws.
 
Intellectual Property
 
Intellectual Property Strategy
 
Our intellectual property strategy is to:  (1) build our own intellectual property portfolio around our Dual Path Platform®DPP® technology; (2) pursue licenses, trade secrets and know-how within the area of rapid point-of-care testing, and (3) develop and acquire proprietary positions to reagents and new hardware platforms for the development and manufacture of rapid diagnostic tests.
 
12

The Company has obtained patent coverage on the DPP® technology, including threefour U.S. patents, and patents in China, Malaysia, Eurasia, Mexico, Singapore, Japan, Australia, Indonesia, Korea and the U.K.  Additional patent applications on the DPP® product linetechnology are pending in the U.S., as well as in many foreign countries such as Australia, Brazil, Canada, the European Union, India, Indonesia, Israel,  Korea, and South Africa.  Patents have also been filed on extensions to the DPP® product line concept, such as 4th generation assays.  The four U.S. patents are as follows:

The Company has also filed for patents and obtained some patents in the U.S. for other inventions, such as its multiple host species veterinary TB test, and patent applications for the other inventions are in various stages from being recently filed and not yet examined, to already examined and allowed but not yet issued.  The Company selectively and strategically foreign files its patent applications based on a number of economic and strategic factors related to the invention.
 
Trademarks
 
The Company has filed and obtained trademarks for its products, including DPP®, SURE CHECK®, and STAT-PAK®. and also for the SampleTainer® used in certain DPP® products.  The DPP® trademark is also registered under the European convention (ECT).  The Company recently filed a trademark for STAT-VIEW®, to market the barrel product in Europe.

Trade Secrets and Know-How
 
We believe that we have developed a substantial body of trade secrets and know-how relating to the development and manufacture of lateral flow and DPP® based-based diagnostic tests, including but not limited to the sourcing and optimization of materials for such tests, and how to maximize sensitivity, speed-to-result, specificity, stability and reproducibility.  The Company possesses proprietary know-how to develop tests for multiple conditions using colored latex.  Our buffer formulations enable extremely long shelf lives of our rapid HIV and other tests and we believe that this provides us with an important competitive advantage.
 
Lateral Flow Technology and Reagent Licenses
 
As part of ourthe agreements executed in 2006 with Alere for the marketing of our HIV tests, we were granted non-exclusive licenses to certain lateral flow technologypatents for certain products manufactured and marketed by Chembio including but not limited to our lateral flow HIV tests.  This license allows us to produce, market and sell assays using lateral flow technologies specifically including our STAT-PAK®, SURE CHECK®, DIPSTICK®, and veterinary product lines.  Under this license agreement, prior to February 3, 2015, we paid royalties to Alere ranging from 5% to 8½%, depending upon the country in which the products are sold.  Even though the relevant patent has expired in most other jurisdictions, or were never issued in markets where we have sold these products, our manufacture of the products in the United States has required that we pay royalties under this license, which has been a substantial expense.  In 2015 our lateral flow royalty expense to Alere was $30,000, and since 2007 we have incurred a total of $2.87 million in lateral flow royalty expenses.  As of February 3, 2015 this royalty expense was no longer payable as the applicable patent expired at that time.
Although we believe our DPP® is outside of the scope of all lateral flow patents of which we are aware, we consult with patent counsel, and seek licenses and/or redesigns of products that we believe to be in the best interests of the Company and our stockholders.  Because of the costs and other negative consequences of time-consuming patent litigation, we often attempt to obtain a license on reasonable terms.  Nevertheless there is no assurance that the Alere lateral flow patents we have licensed will not be challenged or that other patents containing claims relevant to the Company’sCompany's lateral flow or DPP® products will not be granted to third parties and that licenses to such patents, will be available on reasonable terms, if any.  In the past Alere has aggressively enforced its lateral flow intellectual property, although some of the main patents will expire within the next couple of yearshave expired and we are not aware of any patent enforcement litigation that is ongoing with respect to the Alere lateral flow intellectual property.
 
Regardless, the DPP® technology provides us with our own intellectual property.  We believe it provides us with a freedom to operate, and that it also enables tests to be developed with improved sensitivity as compared with comparable tests on lateral flow platforms.  The Company has signed and anticipates signing new development projects based upon the DPP® technology that will provide new manufacturing and marketing opportunities.  We have filed other patentspatent applications that we believe will strengthen the DPP® intellectual property and have also filed for patent protection for certain other point-of-care technologies or applications thereof.
 
The peptides used in our rapid HIV tests were patented by Adaltis Inc. and were licensed to us under a 10-year non-exclusive license agreement dated August 30, 2002.  However, in connection with Adaltis’Adaltis' bankruptcy, during the third quarter of 2009 we bought out all of our remaining obligations under that agreement.  We also have licensed the antigens used in other tests including our Syphilis, Tuberculosis, Leptospirosis, Leishmaniasis and Chagas tests, and we may enter other license agreements.  In prior years we concluded license agreements related to intellectual property rights owned by the United States associated with HIV- 1, and during the first quarter of 2008 we entered into a sub-license agreement for HIV-2 with Bio-Rad Laboratories N.A., the exclusive licensee of the Pasteur Institute’sInstitute's HIV-2 intellectual property estate.

RISK FACTORS
 
You should carefully consider each of the following risk factors and all of the other information provided in this prospectus.  The risks described below are those we currently believe may materially affect us.  An investment in our Company involves a high degree of risk, and should be considered only by persons who can afford the loss of their entire investment.
 
Risks related to our industry, business and strategy
 
IfBecause we aremay not be able to obtain or maintain the necessary regulatory approvals for our laboratories, our manufacturing facilities or some of our products, we may not be able to generate revenues in the amounts we expect, or in the amounts necessary to sustain, continue or grow our business.  Our existing products as well as our manufacturing facility must meet quality standards and are subject to inspection by a number of domestic regulatory and other governmental and non-governmental agencies.
 
All of our proposed and existing products are subject to regulation in the U.S. by the U.S. Food and Drug Administration, the U.S. Department of Agriculture and/or other domestic and international governmental, public health agencies, regulatory bodies or non-governmental organizations.  In particular, we are subject to strict governmental controls on the development, manufacture, labeling, distribution and marketing of our products.  The process of obtaining required approvals or clearances varies according to the nature of, and uses for, a specific product.  These processes can involve lengthy and detailed laboratory testing, human or animal clinical trials, sampling activities, and other costly, time-consuming procedures.  The submission of an application to a regulatory authority does not guarantee that the authority will grant an approval or clearance for that product.  Each authority may impose its own requirements and can delay or refuse to grant approval or clearance, even though a product has been approved in another country.
 
The time taken to obtain approval or clearance varies depending on the nature of the application and may result in the passage of a significant period of time from the date of submission of the application.  Delays in the approval or clearance processes increase the risk that we will not succeed in introducing or selling the subject products, and we may determine to devote our resources to different products.
 
Changes in government regulations could increase our costs and could require us to undergo additional trials or procedures, or could make it impractical or impossible for us to market our products for certain uses, in certain markets, or at all.
 
Changes in government regulations may adversely affect our financial condition and results of operations because we may have to incur additional expenses if we are required to change or implement new testing, manufacturing and control procedures.  If we are required to devote resources to develop such new procedures, we may not have sufficient resources to devote to research and development, marketing, or other activities that are critical to our business.
 
We can manufacture and sell our products only if we comply with regulations and quality standards established by government agencies such as the FDA and the USDA as well as by non-governmental organizations such as the ISO and WHO.  We have implemented a quality system that is intended to comply with applicable regulations.  Although FDA approval is not required for the export of our products, there are export regulations promulgated by the FDA that specifically relate to the export of our products.products that require compliance with FDA quality system regulation ("QSRs") and that also require meeting certain documentary requirements regarding the approval of the product in export markets.  Although we believe that we meet the regulatory standards required for the export of our products, these regulations could change in a manner that could adversely impact our ability to export our products.
 
Our products may not be able to compete with new diagnostic products or existing products developed by well-established competitors, which would negatively affect our business.
 
The diagnostic industry is focused on the testing of biological specimens in a laboratory or at the point-of-care and is highly competitive and rapidly changing.  OurSome of our principal competitors oftenmay have considerably greater financial, technical and marketing resources than we do.  Several companies produce diagnostic tests that compete directly with our testing product line, including but not limited to, OrasureOraSure Technologies, Alere Medical and Trinity Biotech.  Furthermore these and/or other companies have or may have products incorporating molecular and/or other advanced technologies that over time could directly compete with our testing product line. As new products incorporating new technologies enter the market, our products may become obsolete or a competitor’scompetitor's products may be more effective or more effectively marketed and sold than ours.sold.

We have granted Alere exclusive rights to marketThere are competing products that could significantly reduce our SURE CHECK® HIV 1/2 in the United States and non-exclusive rights in the restU.S. sales of the world and exclusive rights to market our HIV 1/2 STAT PAK® in the U.S. only.  Alere has no rapid HIV teststests.
In 2006 Alere, Inc. acquired a division from Abbott Diagnostic located in Japan that are approved for marketing in the U.S.manufactured and Alere is obligated to inform us of any such products within certain time frames.  We believe that Alere is committed to successfully marketing our products in the U.S. Alere may however choose to develop or acquire competing products for marketing in the U.S.  and such an action could have at least a temporary material adverse effect on the marketing of these products until such time as alternative marketing arrangements could be implemented.  In particular Alere manufactures and marketsmarketed a rapid HIV test product line called Determine®.  The Determine® format was developed for the developing world and remote settings and, central to the needs of that with its 3rd generationmarket. The format is essentially a test strip that is integrated into a thin foil wrapper. When opened, the underside of the wrapper serves as the test surface for applying the blood sample and performing the test.  This design reduces costs and shipping weights and volumes and provides an advantage for the developing world markets it serves.  Some of the disadvantages of the platform are the amount of blood sample that is needed (50 microliters versus 2.5, 5 and 10 for our lateral flow barrel, lateral flow cassette, and DPP® products respectively),  the open nature of the test surface, and the absence of a true control that differentiates biological from other kinds of samples.
The so-called "3rd generation" version of this product has been marketed for many years and is the leading productrapid HIV test that is used in a large majority of the developingnational algorithms of countries funded by PEPFAR and the Global Fund, as well as many other countries in the world.  That product is not FDA-approved though it is CE marked. The Determinenewest Determine® HIV test product line,version, which was until 2006 a division of Abbott Diagnosticsdeveloped and manufactured by Alere's subsidiary in Japan that was then sold to Alere, has had at least a few versions, the newest of whichIsrael, Orgenics, is the so called “4th Generation” Determine test which, accordingso-called "4th Generation" version Determine® test. According to its claims, this product detects HIV antibodies and P24 HIV antigen.  The claim of such a 4thantigens. Because the P24 antigen is known to occur in HIV-positive individuals' blood samples before antibodies do, the 4th generation productDetermine® test is that it detectsdesigned to detect HIV infection earlier than tests that solely rely on antibody detection, which required immune response before detection can occur.detection. Chembio's tests, as well as all of the other currently FDA-approved rapid HIV tests, only detect antibodies.  There are however laboratory tests that are FDA-approved that are "4th generation" tests, but they are of course neither rapid nor point-of-care.
The  initial "4th generation" Alere Determine® rapid test product that was also CE marked and that Alere launched internationally some years ago has made statementsnot been successfully commercialized to the best of our knowledge and at  least certain published studies were not favorable for this product.  However the 4th generation product that is now FDA-approved was apparently modified as compared to the initial international version, and it is or will be seekingmay perform more satisfactorily.  Alere received FDA approval of this modified product which, ifin August 2013 and CLIA waiver for it in December 2014. Alere is also aggressively pursuing development of the market for this product.  Moreover there is support by a number of key opinion leaders for the public health value of such 4th generation tests, and this product represents a significant competitive threat to Chembio as well as to each of the other rapid HIV test manufacturers (OraSure and Trinity primarily).
During 2011, Biolytical, Inc. of Vancouver, Canada received FDA approval and in 2012 received CLIA waiver of a flow-through rapid HIV test called "INSTI".  The flow-through technology used in the INSTI test is granted, could potentiallyolder than lateral flow, and requires handling of multiple components (3 vials of solution) to perform the test in multiple steps.  However, these steps can be accomplished in less than ten minutes, and the actual test results occur in only one minute after those steps are completed.  Therefore sample-to-result time is shorter than any of the competitive products.  The product also has good performance claims.  There are settings where that reduced total test time, despite the multiple steps required, may be a competitive product to the Chembiodistinct advantage, and we believe Biolytical has made some progress in penetrating certain public health markets.
Therefore, even though our lateral flow products that Alere markets as Clearview® Complete (barrel) and Clearview HIV ½ STAT PAK® (cassette).  Under our agreements, Alere is in fact expressly permitted to “exploit” suchcurrently enjoy a productsubstantial market share in the United States without breachingU.S. rapid HIV test market, and we have an additional rapid HIV test, the agreement, thoughDPP® HIV 1/2 Assay, there are defined consequencesa number of risks and uncertainties concerning current and anticipated developments in such case:  for the cassette product, Chembio may either terminate Alere or make the agreement with Alere non-exclusive, and for the barrel product, Chembio and StatSure Diagnostics (the other party to the Alere 3-way agreement pertaining to the barrel product) can jointly agree to either continue the agreement with Alere or to also make the barrel agreement non-exclusive.  As part of any decision by Chembio to market either product, Alere would expand the lateral flow license granted to allow Chembio to market the product under Chembio brands.
this market.  Although we have no specific knowledge of any other competitor’snew product that is a significant competitive threat to our products, or that will render our products obsolete, if we fail to maintain and enhance our competitive position or fail to introduce new products and product features, our customers may decide to use products developed by our competitors, which could result in a loss of revenues and cash flow.
We have developed an oral fluid rapid HIV test as well as other applications utilizing our Dual Path Platform® technology, which we believe will enhance our competitive position in HIV rapid testing and other fields.  During 2011 we made significant progress toward the commercialization of this product.  However we still have technical, manufacturing, regulatory and marketing challenges to meet before we will know whether we can successfully commercialize products incorporating this technology.  There can be no assurance that we will overcome these challenges.
We plan to introduce our DPP® oral fluid HIV test, which test also can be used with blood samples, in the U.S. market under a Chembio brand once it is FDA approved, currently anticipated in 2013, but for which there can be no assurance.  Under our 2006 Agreement with Alere, Alere has a right of first negotiation for the right to market any new rapid HIV antibody detection test that we develop.  In accordance with this provision in our agreement, we presented this product to Alere in 2007, and in 2007 Alere waived its right of first negotiation under the agreement.  While such waiver does not prevent Alere from reconsidering the marketing of this product, we have no reason to believe that they will.  Also, although we believe that the primary market opportunity for the DPP® HIV product is for those customers that have a clear preference for an oral fluid HIV test, the product is also likely to compete to some extent with our FDA-approved rapid HIV tests being marketed by Alere.  Therefore this could have a material and adverse effect on our business with Alere.
 
More generally, the point-of-care diagnostics industry is undergoing rapid technological changes, with frequent introductions of new technology-driven products and services.  As new technologies become introduced into the point-of-care diagnostic testing market, we may be required to commit considerable additional efforts, time and resources to enhance our current product portfolio or develop new products.  We may not have the available time and resources to accomplish this, and many of our competitors have substantially greater financial and other resources to invest in technological improvements.  We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers, which would materially harm our operating results.

Although we own our DPP® patent, we own no issued patents covering lateral flow technology, and the field of lateral flow technology is complexstill a competitive platform to DPP®, and characterized by a substantial amount of litigation, so the risk of potential patent challenges is ongoing for us in spite of our DPP® patent.  Moreover, we believe that certain lateral flow patents are going to expire intechnology has a lower cost of manufacture than DPP® products. Although the next couple of years which may materially impact the competitive landscape.
Although we have been granted non-exclusive licenses to the lateral flow patents owned by Alere, there is no assurance that its lateral flow patents will not be challenged or that licenses from other parties may not be required, if available at all.  In addition, certain of the Alere patents will expire in the next couple of years which expiration could open the market to certain competitors.  In the event that it is determined that a license is required and it is not possible to negotiate a license agreement under a necessary patent, we may be able to modify our HIV rapid test products and other products such that a license would not be necessary.  However, there is no assurance that we would be able to do so, and even if accomplished, this alternative could delay or limit our ability to sell these products in the U.S. and other markets, which would adversely affect our results of operations, cash flows and business.
On March 13, 2007, our Dual Path Platform® Immunoassay Device patent application was issued as United States patent no. 7,189,522.  Additional protection for this intellectual property is pending in a number of other countries.  ThisDPP® platform has shown improved sensitivity as compared with conventional lateral flow platforms in a number of studies.  studies, several factors go into the development and performance attributes of products.  Therefore the ability of our products to successfully compete will depend on several other factors, including but not limited to our having a patented rapid test platform technology that differentiates DPP® from lateral flow as well as from other diagnostic platform technologies.
We believe that this new platformour DPP® is outside of the scope of currently issued patents in the field of lateral flow technology, thereby offering the possibility of a greater freedom to operate.  However there can be no assurance that our patents or our products incorporating the patent claims will not be challenged at some time in the future.
Our use of third-party suppliers, some of which may constitute our sole supply source, for certain important product components presents a risk that could have negative consequences for other business.
A number of our components and critical raw materials are provided by third-party suppliers, some of which may be sole-source suppliers, which impacts our ability to manufacture or sell product if our suppliers cannot or will not deliver those materials in a timely fashion, or at all, due to an interruption in their supply, quality or technical issues, or any other reason. If this occurs, we could incur substantial expense and time to be able to reestablish the appropriate quality, cost, regulatory and market-acceptance circumstances needed for commercial success.  Even with the needed expense and time, we may not be able to reestablish any or all of these factors.  The absence of any one or more of these factors could prevent us from being able to commercially produce and market the affected product or products.
 
New developments in health treatments or new non-diagnostic products may reduce or eliminate the demand for our products.
 
The development and commercialization of products outside of the diagnostics industry could adversely affect sales of our products.  For example, the development of a safe and effective vaccine to HIV or treatments for other diseases or conditions that our products are designed to detect, could reduce or eventually eliminate the demand for our HIV or other diagnostic products and result in a loss of revenues.
 
We may not have sufficient resources to effectively introduce and market our products, which could materially harm our operating results.
 
Introducing and achieving market acceptance for our rapid HIV tests and other new products will require substantial marketing efforts and will require us and/or our contract partners, sales agents, and/or distributors to make significant expenditures of time and money. In some instances we will be significantly or totally reliant on the marketing efforts and expenditures of our contract partners, sales agents, and/or distributors.  If they do not have or commit the expertise and resources to effectively market the products that we manufacture, our operating results will be materially harmed.
 
The success of our business depends on, in addition to the market success of our products, our ability to raise additional capital through the sale of debt or equity or through borrowing.  Ifborrowing, and we aremay not be able to raise capital or borrow funds on attractive terms and/or in amounts necessary to continue our business, our business may not be able to develop, manufacture, obtain regulatory approval or sell our products in the manner and according to the timetable that is desirable for the Company.at all.
 
Our revenues and gross margins have increased significantly in recent periods, and we have beenWe were profitable for threefive consecutive years.years through 2013.  Nevertheless, prior to 2009 we sustained significant operating losses since 2004.  At December 31, 2011,2004, and we had a stockholders’ equityincurred an operating loss for 2014 and 2015.     We  estimate that our resources are sufficient to fund our needs through the end of $12.5 million2016 and a working capital surplus of $6.1 million.  The Company’sbeyond.   Nevertheless we have already made, and may continue to make, significant financial commitments to invest in our sales and marketing organization, regulatory approvals, research and development including new technologies, and production capacity, including expanded facilities.
Our liquidity and cash requirements will depend on several factors. These factors include (1) the level of revenues; (2) the extent to which, if any, that revenue level improves operating cash flows; (3) the Company’sour investments in research and development, facilities, marketing, regulatory approvals, and other investments itwe may determine to make; and (4) the Company’sour investment in capital equipment and the extent to which it improves cash flow through operating efficiencies. There are no assurances that the Companywe will remain profitable or generate positive cash flow in 2013for 2016 or, in the alternative, be successful in raising sufficient capital to fund itsour needs through 2013 and thereafter.after 2016.

Continued revenues from Alere fromOur U.S. market sales are difficult to predict in 2016 given (i) our early June 2014 termination of the agreement with a third party for exclusive distribution of our cassette product in the U.S; and (ii) the impending May 31, 2016 termination of the agreement with a third party for exclusive distribution of our barrel product in the U.S.  rapid HIV test market and increased sales to developing world markets are critical for usAs a result of these terminations, we expect to continue to maintainexperience higher average revenue per unit, and increasea lower volume of U.S. sales, of the cassette and barrel products.  Higher revenue per unit is anticipated because we previously sold these products to the exclusive U.S. distributor at a significantly lower price than the price at which the distributor resold these products to customers (including re-sellers and distributors) in the United States.  However at this point with respect to the barrel product, this can occur only after any inventory that the exclusive U.S. distributor has accumulated is consumed, which may take several months. In addition, in marketing these products directly, we are incurring substantial costs associated with developing our profitability while funding our new product regulatory approvalsales and commercialization programs.  If we fail to meet any of these objectives, our lower cash flow, profitabilitymarketing organization and research and development will have a material negative effect on our business and on our ability to meet our operating expenses and other costs, amounts necessary to maintain and increase our profitability and/or to fund our planned research, development, regulatory, selling, general and administrative expenses in 2012.channel distribution partners.
 
We intendbelieve that underlying demand for HIV rapid testing in the United States remains strong, and that the restoration of some of the funding cutbacks from sequestration and the implementation of the Affordable Care Act and of the United States Preventive Services Task Force recommendations will have a positive impact on the development of the market.  Further, our products are well established and relied upon by a large installed base of customers over many years of use in the U.S. global market, and we believe this is a strong advantage. We also believe that our DPP® HIV 1/2 Assay for which CLIA waiver was obtained in October 2014, for use with oral fluid or bloods samples will be able to attemptserve new customers that were previously unavailable to us with our lateral flow blood tests.  However, development of new customers with this product is costly and time-consuming.
We are attempting to increase international sales of our products, despiteand we have invested in additional resources in connection with this effort; but as we have experienced, the factnature of international business is such that our current contracts in Brazil provide forit can be volatile from period to period, depending on ordering patterns of donor-funded programs.
Furthermore, a decline in revenue over the next few years.  A number of factors can slow or prevent international sales increases or cause sales decreases, or substantially increase the cost of internationalachieving sales including:assuming they are achieved. These factors include:
 
·  economic conditions and the absence of or reduction in available funding sources;
regulatory requirements and customs regulations;
·  cultural and political differences;
·  foreign exchange rates, currency fluctuations and tariffs;
·  dependence on and difficulties in managing international distributors or representatives;
·  the creditworthiness of foreign entities;
·  difficulties in foreign accounts receivable collection;
·  competition;competition
·  pricing; and
·  economic conditions and the absence of available funding sources.any inability we may have in maintaining or increasing revenues.

If we are unable to maintain or increase our revenues from domestic and/or international sales,customers, our operating results will be materially harmed.
 
21

Although we have an ethics and anti-corruption policy in place, and have no knowledge or reason to know of any practices by our employees, agents or distributors that could be construed as in violation of such policies, our business includes sales of products to countries where there is or may be widespread corruption.  If these policies were violated, our business and our Company could be materially and negatively affected.
 
Chembio has a policy in place prohibiting its employees, distributors and agents from engaging in corrupt business practices, including activities prohibited by the United States Foreign Corrupt Practices Act (FCPA)(the "FCPA"). Nevertheless, because we work through independent sales agents and distributors (and do not have any employees or subsidiaries) outside the United States, we do not have control over the day-to-day activities of such independent agents and distributors. In addition, in the donor- fundeddonor-funded markets in Africa where we sell our products, there is significant oversight from PEPFAR, the Global Fund, and advisory committees comprised of technical experts concerning the development and establishment of national testing protocols.  This is a process that includes an overall assessment of a product which includes extensive product performance evaluations including five active collaborations and manufacturer’smanufacturer's quality systems, as well as price and delivery.  In Brazil, where we have had a total of six product collaborations with FIOCRUZ, thosethe programs thatthrough which our products are or may be deployed in are all funded by the Brazilian Ministry of Health. Although FIOCRUZ is affiliated with the Brazilian Ministry of Health, itand is its sole customer, FIOCRUZ is not itsthe exclusive supplier.supplier for the Ministry of Health. However, because each of our previous collaborations with FIOCRUZ incorporates a technology transfer aspect, we believe we have a competitive advantage versus other suppliers to the Brazilian Ministry of Health, assuming other aspects of our product offering through FIOCRUZ are otherwise competitive in comparison. We have no knowledge or reason to know of any activities by our employees, distributors or sales agents of any actions which could be in violation of the FCPA, although there can be no assurance of this.
 
If our patents and licenses, together withWe rely on trade secret laws and agreements with our key employees and other third parties are not adhered to or otherwise are not adequate to protect our proprietary rights, thenand we cannot be sure that these laws or agreements adequately protect our business will be increasingly damaged by competitors.rights.
 
We believe that factors such as the technological and creative skills of our personnel, strategic relationships, new product developments, frequent product enhancements and name recognition are essential to our success.  All of our management and technological personnel are bound by non-disclosure agreements.  If personnel leave our employment, in some cases we would be required to protect our intellectual property rights pursuant to common law theories which may be less protective than provisions of employment, non-competition or non-disclosure agreements.
 
17

We seek to protect our proprietary products under trade secret and copyright laws, enter into license agreements for various materials and methods employed in our products, and enter into strategic relationships for distribution of the products.  These strategies afford only limited protection.  We currently have some foreign patents issued, and we are seeking additional patent protection in several other foreign jurisdictions for our DPP® technology.  We have licenses to reagents (antigens and peptides) used in several of our products and products under development.  Despite our efforts to protect our proprietary assets, and respect the intellectual property rights of others, we participate in several markets where intellectual property rights protections are of little or no value.  This can place our products and our company at a competitive disadvantage.
 
Despite the efforts we make to protect our confidential information, such as entering into confidentiality agreements in connection with new business opportunities, unauthorized parties may attempt to copy aspects of our products or to obtain information that we regard as proprietary.  We may be required to expend substantial resources in asserting or protecting our intellectual property rights, or in defending suits related to intellectual property rights.  Disputes regarding intellectual property rights could substantially delay product development or commercialization activities because some of our available funds would be diverted away from our business activities.  Disputes regarding intellectual property rights might include state, federal or foreign court litigation as well as patent interference, patent reexamination, patent reissue, or trademark opposition proceedings in the U.S. Patent and Trademark Office.
 
To facilitate development and commercialization of a proprietary technology base, we may need to obtain additional licenses to patents or other proprietary rights from other parties.  Obtaining and maintaining these licenses, which may not be available, may require the payment of up-front fees and royalties.  In addition, if we are unable to obtain these types of licenses, our product development and commercialization efforts may be delayed or precluded.
 
Failure to retain

Our continued growth depends on retaining our current key employees and to attractattracting additional qualified personnel, could adversely affect our abilityand we may not be able to create, develop, manufacture, sell and/or market our products.do so.
 
Our success will depend to a large extent upon the skills and experience of our executive officers, management and sales, marketing, operations and scientific staff.  We may not be able to attract or retain qualified employees in the future due to the intense competition for qualified personnel among medical products businesses, geographic considerations, our ability to offer competitive compensation, relocation packages, benefits, and/or other reasons.
 
If we are not able to attract and retain the necessary personnel to accomplish our business objectives, we may experience constraints that will adversely affect our ability to effectively manufacture, sell and market our products to meet the demands of our strategic partners in a timely fashion, or to support internal research and development programs for new or advanced products.programs.  Although we believe we will be successful in attracting and retaining qualified personnel, competition for experienced scientists and other personnel from numerous companies and academic and other research institutions may limit our ability to do so on acceptable terms.
 
We have entered into employment contracts with our Chief Executive Officer, and President, Lawrence Siebert,John Sperzel, our Chief Operating Officer, Sharon Klugewicz, and our Senior Vice President of Research and Development,Chief Scientist & Technology Officer , Javan Esfandiari.  Due to the specific knowledge and experience of these executives regarding the industry, technology and market, the loss of the services of eitherany one of them would likelycould have a material adverse effect on the Company.  The contract with Mr. Siebert provides that Mr. Siebert will serve as the Chief Executive Officer and PresidentSperzel has a term of the Company throughthree years ending March 2017. The contract with Ms. Klugewicz has a term of two years ending May 11, 2013.2017.  The contract with Mr. Esfandiari has a term of three years ending March 2013.  We have2019.  The Company has obtained a key man insurance policy foron Mr. Esfandiari.  The contract with Mr. Sperzel provides that Mr. Sperzel will serve as the Chief Executive Officer and as a Director of the Company through March 13, 2017.

We may not be ablebelieve our success depends in part on the continued funding of and our ability to participate in large testing programs in the U.S. and worldwide,worldwide.  Funding of these and failureor similar programs may be reduced, discontinued and/or we may not be able to do so may inhibit our future growth and success.participate for other reasons.
 
We believe it to be in our best interests to meaningfully participate in large testing programs.  Moreover many of these programs are funded by governments and other donors, and there can be no assurance that funding will not be reduced or completely discontinued.  Participation in these programs also requires alignment and engagement with the many other participants in these programs, including the World Health Organization, U.S. Center for Disease Control, U.S. Agency for International Development, foreign governments and their agencies, non-governmental organizations, and HIV service organizations.  If we are unsuccessful in our efforts to participate in these programs, our operating results could be materially harmed.
 
In December 2013 President Obama signed into law the PEPFAR Stewardship and Oversight Act, which is the most recent reauthorization of PEPFAR. However, unlike the 2008 PEPFAR authorization, which authorized approximately $45 billion in funding, the new law does not authorize a specific dollar amount for funding.  Nevertheless it is widely anticipated that PEPFAR will continue to enjoy strong funding; the FY14 budget has $6 billion for global HIV/AIDS assistance, including $4 billion for PEPFAR.
To the extent that we are unable to collect our outstanding accounts receivable, our operating results could be materially harmed.
There may be circumstances and timing that require us to accept payment terms, including delayed payment terms, from distributors or customers, which, if not satisfied, could cause financial losses.
We generally accept payment terms which require us to ship product before the contract price has been paid fully, and there also are circumstances pursuant to which we may accept further delayed payment terms pursuant to which we may continue to deliver product.  To the extent that these circumstances result in significant accounts receivables and those accounts receivables are not paid on a timely basis, or are not paid at all, especially if concentrated in one or two customers, we could suffer financial losses.

From the inception of Chembio Diagnostic Systems, Inc. in 1985 through the period ended December 31, 2008, we incurred net losseslosses.  We were then profitable each year from 2009 through 2013.  In 2014 and 2015, we have only become profitable during the last three years.  While we anticipate growth in our product revenues in 2012 as compared with 2011, there can be no assurance of this.  Moreover in 2012 we expect to makemade substantial expenditures for sales and marketing, regulatory submissions, product development, production and warehouse capacity, and other purposes, which may impact profitability.and we incurred a net operating loss.  Our ability to continuere-achieve profitability in the future will primarily depend on our ability to increase sales of our products based on having made the aforementioned expenditures to reduce production and other costs, and to successfully introduce new products and enhanced versions of our existing products into the marketplace.  If we are unable to increase our revenues at a rate that is sufficient to achieve profitability, or adequately control and reduce our operating costs, our operating results would be materially harmed.
 
To the extent that we are unable to obtain sufficient product liability insurance or that we incur product liability exposure that is not covered by our product liability insurance, our operating results could be materially harmed.
 
We may be held liable if any of our products, or any product which is made with the use or incorporation of any of the technologies belonging to us, causes injury of any type or is found otherwise unsuitable during product testing, manufacturing, marketing, sale or usage.use.  We have obtained product liability insurance even though we have never received a product liability claim, and have generally not seen product liability claims for screening tests that are accompanied by appropriate disclaimers.  Nevertheless, in the event there is a claim, this insurance may not fully cover our potential liabilities.  In addition, as we attempt to bring new products to market, we may need to increase our product liability coverage which wouldcould be a significant additional expense that we may not be able to afford.  If we are unable to obtain sufficient insurance coverage at an acceptable cost to protect us, we may be forced to abandon efforts to commercialize our products or those of our strategic partners, which would reduce our revenues.

Our authorized capital stock consists of 10,000,000 shares of our preferred stock, par value $0.01 per share.  Under our Articles of Incorporation, as amended, we may issue shares of preferred stock in one or more series, as may be determined by our Board of Directors or a duly authorized committee.  Our Board of Directors or a committee thereof also may establish, from time to time, the number of shares to be included in each series and may fix the designation, powers, preferences and rights of the shares of each such series and any qualifications, limitations or restrictions thereof, and may increase or decrease the number of shares of any series without any further vote or action by the stockholders.  Any preferred stock we may issue will rank senior to our common stock with respect to the payment of dividends or amounts paid upon liquidation, dissolution or winding up of our Company, or both.  In addition, any shares of our preferred stock may have class or series voting rights.
 
We have adopted a Shareholder Rights Agreement, which under certain circumstances would significantly impair the ability of third parties to acquire control of us without prior approval of our Board of Directors thereby discouraging unsolicited takeover proposals.  The preferred stock issued under the Shareholder Rights Agreement would cause substantial dilution to a person or group that attempts to acquire us on terms not approved in advance by our Board of Directors. No shares of preferred stock are currently outstanding.  Each series of preferred stock will be issued under a Certificate of Designation, which will be filed with the SEC as an exhibit to a document incorporated by reference in this prospectus concurrently with the offering of such preferred stock.  It is also subject to our Articles of Incorporation, as amended, which is incorporated by reference as an exhibit to this registration statement.

the distinctive serial designation of such series and the number of shares to constitute such series;
 
the voting rights, if any;
 
the dividend rate;
 
whether dividends are cumulative and, if so, the date from which dividends cumulate;
 
the payment date for dividends;
 
redemption rights, the applicable redemption prices and such other conditions of redemption;
 
amounts payable to holders on our liquidation, dissolution or winding up;
 
the amount of the sinking fund, if any;
 
whether the shares will be convertible or exchangeable into equity, and, if so, the prices and terms of conversion and such other terms and conditions of such conversion or exchange; and
 
any other voting powers, designations, preferences, limitations, restrictions, and relative rights rights..
 
The preferred stock will be, when issued, fully paid and non-assessable.  Holders of preferred stock will not have any preemptive or subscription rights to acquire more stock of the Company.
 
The transfer agent, registrar, dividend disbursing agent and redemption agent for shares of each series of preferred stock will be named in the prospectus supplement relating to such series.
 
The rights of holders of the preferred stock offered may be adversely affected by the rights of holders of any shares of preferred stock that may be issued in the future.  The Board of Directors may cause shares of preferred stock to be issued in public or private transactions for any proper corporate purpose.  Examples of proper corporate purposes include issuances to obtain additional financing in connection with acquisitions or otherwise, and issuances to our officers, directors and employees and our subsidiaries pursuant to benefit plans or otherwise.

Liquidation Preference

PLAN OF DISTRIBUTION
 
We may sell the securities described in this prospectus to or through one or more agents, underwriters, dealers or directly to purchasers on a continuous or delayed basis.
 
The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed from time to time, at market prices prevailing at the times of sale, at prices related to such prevailing market prices or at negotiated prices.
 
Each time that we use this prospectus to sell our securities, we will also provide a prospectus supplement.  For each series of securities, the applicable prospectus supplement will set forth the terms of the offering including:
 
the public offering price;
 
the name or names of any underwriters, dealers or agents;
 
the purchase price of the securities;
30

 
the proceeds from the sale of the securities to us;
 
any underwriting discounts, agency fees, or other compensation payable to underwriters or agents;
 
any discounts or concessions allowed or reallowed or repaid to dealers; and
 
the securities exchanges on which the securities will be listed, if any.
 
If we use underwriters in the sale of securities, the securities will be acquired by the underwriters for their own account.  The underwriters may then resell the securities in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale or thereafter.  The securities may be either offered to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters.  The obligations of the underwriters to purchase the securities will be subject to certain conditions.  The underwriters will be obligated to purchase all the securities offered if they purchase any securities.  The public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.
 
If we use dealers in the sale of securities, we will sell securities to such dealers as principals.  The dealers may then resell the securities to the public at varying prices to be determined by such dealers at the time of resale.  We may solicit offers to purchase the securities directly, and we may sell the securities directly to institutional or other investors, who may be deemed underwriters within the meaning of the Securities Act with respect to any resales of those securities.  The terms of these sales will be described in the applicable prospectus supplement.  If we use agents in the sale of securities, unless otherwise indicated in the prospectus supplement, they will use their reasonable best efforts to solicit purchases for the period of their appointment.  Unless otherwise indicated in a prospectus supplement, if we sell directly, no underwriters, dealers or agents would be involved.  We will not make an offer of securities in any jurisdiction that does not permit such an offer.
 
26

We may grant underwriters who participate in the distribution of securities an option to purchase additional securities to cover overallotments, if any, in connection with the distribution.  Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with SEC orders, rules and regulations and applicable law.  To the extent permitted by applicable law and SEC orders, rules and regulations, an overallotment involves sales in excess of the offering size, which create a short position.  Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.  To the extent permitted by applicable law and SEC orders, rules and regulations, short covering transactions involve purchases of the common stock in the open market after the distribution is completed to cover short positions.  Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the common stock originally sold by the dealer is purchased in a covering transaction to cover short positions.  Those activities may cause the price of the common stock to be higher than it would otherwise be.  If commenced, the underwriters may discontinue any of the activities at any time.
 
Any underwriters who are qualified market makers on the NASDAQ trading market may engage in passive market making transactions in the common stock on the NASDAQ trading market in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the common stock.  Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers.  In general a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’smaker's bid, however, the passive market maker’smaker's bid must then be lowered when certain purchase limits are exceeded.
 
Underwriters, dealers and agents that participate in any distribution of securities may be deemed to be underwriters as defined in the Securities Act.  Any discounts, commissions or profit they receive when they resell the securities may be treated as underwriting discounts and commissions under the Securities Act of 1933.  Only underwriters named in the prospectus supplement are underwriters of the securities offered in the prospectus supplement.  We may have agreements with underwriters, dealers and agents to indemnify them against certain civil liabilities, including certain liabilities under the Securities Act, or to contribute with respect to payments that they may be required to make.
 
31

We may authorize underwriters, dealers or agents to solicit offers from certain institutions whereby the institution contractually agrees to purchase the securities from us on a future date at a specific price.  This type of contract may be made only with institutions that we specifically approve.  Such institutions could include banks, insurance companies, pension funds, investment companies and educational and charitable institutions.  The underwriters, dealers or agents will not be responsible for the validity or performance of these contracts.
 
Each series of securities will be a new issue of securities and will have no established trading market, other than our common stock, which is listed on the NASDAQ trading market.  Unless otherwise specified in the applicable prospectus supplement, the securities will not be listed on any exchange.  It has not presently been established whether the underwriters, if any, of the securities will make a market in the securities.  If the underwriters make a market in the securities, such market making may be discontinued at any time without notice.  No assurance can be given as to the liquidity of the trading market for the securities.
 
Agents, dealers and underwriters may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the agents, dealers or underwriters may be required to make in respect thereof.  Agents, dealers or underwriters may be customers of, engage in transactions with, or perform services for us and our subsidiaries in the ordinary course of business.

Item 15. Indemnification of Directors and Officers.
 
Nevada law permits a Nevada corporation, such as the Registrant, to indemnify its directors and officers in certain circumstances.  Specifically, Section 78.7502 of the NRS provides as follows:

Indemnification of directors and officers.
 
(1) A corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative, except an action by or in the right of the corporation, by reason of the fact that he is or was a director or officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director or officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses including attorneys’attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he: (a) is not liable pursuant to NRS 78.138 or (b) acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful.  The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere, or its equivalent, does not, of itself, create a presumption that the person is liable pursuant to NRS 78.138 or did not act in good faith and in a manner which he reasonable believed to be in or not opposed to the bests interests of the corporation, or that, with respect to any criminal action or proceedings, he had reasonable cause to believe that his conduct was unlawful.

(2) A corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he is or was a director or officer, employee or agent of the corporation, or is or was serving at the request of the corporation, or is or was serving at the request of the corporation as a director or officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses including amounts paid in settlement and attorneys’attorneys' fees actually and reasonably incurred by him in connection with the defense or settlement of the action or suit if he (a) is not liable pursuant to NRS 78.138 or (b) acted in good faith and in a manner which he reasonably believed to be in or not, opposed to the best interests of the corporation.  Indemnification may not be made for any claim, issue or matter as to which such a person shall have been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable for negligence or misconduct in the performance of his duty to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which such action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

35

(3) To the extent that a director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (1) or (2) of this section, or in the defense of any claim, issue or matter therein, the corporation shall indemnify him against expenses, including attorneys’attorneys' fees, actually and reasonably incurred by him in connection therewith.

The Registrant’sRegistrant's bylaws provide that it will indemnify any of its directors or officers against expenses (including attorneys’attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, relating to service for or at the request of the Registrant.  The Registrant will not indemnify a director or officer if in relation to matters such director or officer is adjudged in the action, suit or proceeding to be liable for negligence or misconduct in the performance of their duties.

The Registrant’sRegistrant's articles of incorporation also provide that no director will be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except that the director’sdirector's liability will not be eliminated or limited: (A) for acts or omissions involving intentional misconduct, fraud or a knowing violation of the law; or (B) for the payment of any distribution in violation of Nevada law.

Item 17. Undertakings
 
The undersigned Registrant hereby undertakes:
 
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

3136

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement.  Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation"Calculation of Registration Fee”Fee" table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(A) Each prospectus filed by a Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus.  As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

32

(5) That, for the purpose of determining liability of a Registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, each undersigned Registrant undertakes that in a primary offering of securities of an undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of an undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

37

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of an undersigned Registrant or used or referred to by an undersigned Registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about an undersigned Registrant or its securities provided by or on behalf of an undersigned Registrant; and

(iv) Any other communication that is an offer in the offering made by an undersigned Registrant to the purchaser.

(6) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’sRegistrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’splan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of each Registrant pursuant to the foregoing provisions, or otherwise, each Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by a Registrant of expenses incurred or paid by a director, officer or controlling person of a Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, that Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
