PART I

Item 1. Description of Business

Overview

We are a Delaware corporation founded in 1997 by health professionals, scientists and engineers affiliated with Columbia University to develop advanced End Stage Renal Disease, or ESRD, therapy technology and products that would address both patient treatment needs and the clinical and financial needs of the treatment provider. In the course of our extensive development, we have diversified into infection control in the form of our Dual Stage Ultrafilter water filtration products.

We currently have three products in various stages of development in the hemodiafiltration, or HDF, modality to deliver improved therapy to ESRD patients:

OLpur MDHDF filter series (which we sell in various countries in Europe and currently consists of our MD190 and MD220 diafilters); to our knowledge, the only filter designed expressly for HDF therapy and employing our proprietary Mid-Dilution Diafiltration technology;
OLpur H 2 H, our add-on module designed to allow the most common types of hemodialysis machines to be used for HDF therapy; and
OLpur NS2000 system, our stand-alone HDF machine and associated filter technology.

We have also developed our OLpur HD 190 high-flux dialyzer cartridge, which incorporates the same materials as our OLpur MD series but does not employ our proprietary Mid-Dilution Diafiltration technology. Our OLpur HD190 was designed for use with either hemodialysis or hemodiafiltration machines, and received its approval from the U.S. Food and Drug Administration, or the FDA, under Section 510(k) of the Food, Drug and Cosmetic Act, or the FDC Act, in June 2005.

OLpur and H 2 H are among our trademarks for which U.S. registrations are pending. H 2 H is a registered European Union trademark. We have assumed that the reader understands that these terms are source-indicating. Accordingly, such terms appear throughout the remainder of this Annual Report without trademark notices for convenience only and should not be construed as being used in a descriptive or generic sense.

We believe that products in our OLpur MDHDF filter series are more effective than any products currently available for ESRD therapy, because they are better at removing certain larger toxins (known in the industry as “middle molecules” because of their heavier molecular weight) from blood. The accumulation of middle molecules in the blood has been related to such conditions as malnutrition, impaired cardiac function, carpal tunnel syndrome, and degenerative bone disease in the ESRD patient. We also believe that OLpur H 2 H will, upon introduction, expand the use of HDF as a cost-effective and attractive alternative for ESRD therapy, and that, if approved in 2008, our OLpur H 2 H and MDHDF filters will be the first, and only, HDF therapy available in the United States at that time.

We believe that our products will reduce hospitalization, medication and care costs as well as improve patient health (including reduced drug requirements and improved blood pressure profiles), and therefore, quality of life, by removing a broad range of toxins through a more patient-friendly, better-tolerated process. In addition, independent studies in Europe have indicated that, when compared with dialysis as it is currently offered in the United States, HDF can reduce the patient’s mortality risk by up to 35%. We believe that the OLpur MDHDF filter series and the OLpur H 2 H will provide these benefits to ESRD patients at competitive costs and without the need for ESRD treatment providers to make significant capital expenditures in order to use our products. We also believe that the OLpur NS2000 system, if successfully developed, will be the most cost-effective stand-alone hemodiafiltration system available.

In January 2006, we introduced our new Dual Stage Ultrafilter (the “DSU”) water filtration system. Our DSU represents a new and complementary product line to our existing ESRD therapy business. The DSU incorporates our unique and proprietary dual stage filter architecture and is, to our knowledge, the only water filter that allows the user to sight-verify that the filter is properly performing its cleansing function. Our research and development work on the OLpur H 2 H and MD Mid-Dilution filter technologies for ESRD therapy provided the foundations for a proprietary multi-stage water filter that we believe is cost effective,

TABLE OF CONTENTS

extremely reliable, and long-lasting. We believe our DSU can offer a robust solution to a broad range of contaminated water and disease prevention issues. Hospitals are particularly stringent in their water quality requirements; transplant patients and other individuals whose immune systems are compromised can face a substantial infection risk in drinking or bathing with standard tap water that would generally not present a danger to individuals with normal immune function. The DSU is designed to remove a broad range of bacteria, viral agents and toxic substances, including salmonella, hepatitis, cholera, HIV, Ebola virus, ricin toxin, legionella, fungi and e-coli. During January 2006, we received our first purchase order for our DSU from a major hospital in New York City. The hospital conducted an evaluation of our DSUs by installing them in a sampling of the hospital’s patient showers. Upon completion of the first phase, the hospital ordered additional DSU units in December 2006 to continue its evaluation. We are currently in discussions with this and other hospitals regarding potential application of our products as a part of their infection control strategy. With over 5,000 registered hospitals in the United States alone (as reported by the American Hospital Association in Fast Facts of October 20, 2006), we believe the hospital shower and faucet market can offer us a valuable opportunity as a first step in water filtration.

The Defense Department budgets for fiscal 2007 and fiscal 2008 include an aggregate of $3 million in appropriations for the U.S. Marine Corps for development of our dual stage ultra reliable personal water filtration system. We are currently working with military laboratories to define the current project scope and objectives in connection with these appropriations. We have also introduced the DSU to various government agencies as a solution to providing potable water in certain emergency response situations. We have also begun investigating a range of commercial, industrial and retail opportunities for our DSU technology.

Going Concern

The financial statements included in this Annual Report on Form 10-KSB have been prepared assuming that we will continue as a going concern, however, there can be no assurance that we will be able to do so. Our recurring losses and difficulty in generating sufficient cash flow to meet our obligations and sustain our operations raise substantial doubt about our ability to continue as a going concern, and our consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

We have incurred losses in our operations in each quarter since inception. For the years ended December 31, 2007 and 2006, we have incurred a net loss of approximately $26.4 million and $8.0 million, respectively. In addition, we have not generated positive cash flow from operations for the twelve months ended December 31, 2007 and 2006. To become profitable, we must increase revenue substantially and achieve and maintain positive gross and operating margins. If we are not able to increase revenue and gross and operating margins sufficiently to achieve profitability, our results of operations and financial condition will be materially and adversely affected.

At December 31, 2007, we had approximately $3,449,000 in cash and cash equivalents and $4,700,000 in short-term investments. There can be no assurance that our short-term investments will provide the liquidity we expect. (See “Certain Risks and Uncertainties”). These operating plans primarily include the continued development and support of our business in the European market, continuation and completion of the US clinical trial for the H 2 H, organizational changes necessary to begin the commercialization of our water filtration business and the completion of current year milestones which are included in the Office of Naval Research appropriation.

There can be no assurance that our future cash flow will be sufficient to meet our obligations and commitments. If we are unable to generate sufficient cash flow from operations in the future to service our commitments we will be required to adopt alternatives, such as seeking to raise debt or equity capital, curtailing our planned activities or ceasing our operations. There can be no assurance that any such actions could be effected on a timely basis or on satisfactory terms or at all, or that these actions would enable us to continue to satisfy our capital requirements.

We continue to investigate additional funding opportunities, talking to various potential investors who could provide financing. However, there can be no assurance that we will be able to obtain further financing, do so on reasonable terms, do so on terms that will satisfy the continued listing standards of the American Stock Exchange (the “AMEX”) or do so on terms that would not substantially dilute your equity interests in

us. If we are unable to raise additional funds on a timely basis, or at all, we will not be able to continue our operations and we may be de-listed from the AMEX.

Current ESRD Therapy Options

Current renal replacement therapy technologies include (1) two types of dialysis, peritoneal dialysis and hemodialysis, (2) hemofiltration and (3) hemodiafiltration, a combination of hemodialysis and hemofiltration. Dialysis can be broadly defined as the process that involves movement of molecules across a semipermeable membrane. In hemodialysis, hemofiltration or hemodiafiltration, the blood is exposed to an artificial membrane outside of the body. During Peritoneal Dialysis (PD), the exchange of molecules occurs across the membrane lining of the patient’s peritoneal cavity. While there are variations in each approach, in general, the three major categories of renal replacement therapy in the marketplace today are defined as follows:

Peritoneal Dialysis , or PD, uses the patient’s peritoneum, the membrane lining covering the internal abdominal organs, as a filter by introducing injectable-grade dialysate solution into the peritoneal cavity through a surgically implanted catheter. After some period of time, the fluid is drained and replaced. PD is limited in use because the peritoneal cavity is subject to scarring with repeated episodes of inflammation of the peritoneal membrane, reducing the effectiveness of this treatment approach. With time, a PD patient’s kidney function continues to deteriorate and peritoneal toxin removal alone may become insufficient to provide adequate treatment. In such case the patient may switch to an extracorporeal renal replacement therapy such as hemodialysis or hemodiafiltration.
Hemodialysis uses an artificial kidney machine to remove certain toxins and fluid from the patient’s blood while controlling external blood flow and monitoring patient vital signs. Hemodialysis patients are connected to a dialysis machine via a vascular access device. The hemodialysis process occurs in a dialyzer cartridge with a semi-permeable membrane which divides the dialyzer into two chambers: while the blood is circulated through one chamber, a premixed solution known as dialysate circulates through the other chamber. Toxins and excess fluid from the blood cross the membrane into the dialysate solution through a process known as “diffusion.”
Hemodiafiltration, or HDF, in its basic form combines the principles of hemodialysis with hemofiltration. Hemofiltration is a cleansing process without dialysate solution where blood is passed through a semi-permeable membrane, which filters out solute particles. HDF uses dialysate solution with a negative pressure (similar to a vacuum effect) applied to the dialysate solution to draw additional toxins from the blood and across the membrane. This process is known as “convection.” HDF thus combines diffusion with convection, offering efficient removal of small solutes by diffusion, with improved removal of larger substances (i.e., middle molecules) by convection.

Hemodialysis is the most common form of extracorporeal renal replacement therapy and is generally used in the United States. Hemodialysis fails, in our opinion, to address satisfactorily the long-term health or overall quality of life of the ESRD patient. We believe that the HDF process, which is currently available in our Target European Market and Japan, offers improvement over other dialysis therapies because of better ESRD patient tolerance, superior blood purification of both small and middle molecules, and a substantially improved mortality risk profile.

Current Dialyzer Technology used with HDF Systems

In our view, treatment efficacy of current HDF systems is limited by current dialyzer technology. As a result of the negative pressure applied in HDF, fluid is drawn from the blood and across the dialyzer membrane along with the toxins removed from the blood. A portion of this fluid must be replaced with a man-made injectable grade fluid, known as “substitution fluid,” in order to maintain the blood’s proper fluid volume. With the current dialyzer technology, fluid is replaced in one of two ways: pre-dilution or post-dilution.

With pre-dilution, substitution fluid is added to the blood before the blood enters the dialyzer cartridge. In this process, the blood can be over-diluted, and therefore more fluid can be drawn across

3


TABLE OF CONTENTS

the membrane. This enhances removal of toxins by convection. However, because the blood is diluted before entering the device, it actually reduces the rate of removal by diffusion; the overall rate of removal, therefore, is reduced for small molecular weight toxins (such as urea) that rely primarily on diffusive transport.
With post-dilution, substitution fluid is added to blood after the blood has exited the dialyzer cartridge. This is the currently preferred method because the concentration gradient is maintained at a higher level, thus not impairing the rate of removal of small toxins by diffusion. The disadvantage of this method, however, is that there is a limit in the amount of plasma water that can be filtered from the blood before the blood becomes too viscous, or thick. This limit is approximately 20% to 25% of the blood flow rate. This limit restricts the amount of convection, and therefore limits the removal of middle and larger molecules.

The Nephros Mid-Dilution Diafiltration Process

Our OLpur MDHDF filter series uses a design and process we developed called Mid-Dilution Diafiltration, or MDF. MDF is a fluid management system that optimizes the removal of both small toxins and middle-molecules by offering the advantages of pre-dilution HDF and post-dilution HDF combined in a single dialyzer cartridge. The MDF process involves the use of two stages: in the first stage, blood is filtered against a dialysate solution, therefore providing post-dilution diafiltration; it is then overdiluted with sterile infusion fluid before entering a second stage, where it is filtered once again against a dialysate solution, therefore providing pre-dilution diafiltration. We believe that the MDF process provides improved toxin removal in HDF treatments, with a resulting improvement in patient health and concurrent reduction in healthcare costs.

Our ESRD Therapy Products

Our products currently available or in development with respect to ESRD Therapy include:

OLpur MDHDF Filter Series

OLpur MD190 and MD220 constitute our dialyzer cartridge series that incorporates the patented MDF process and is designed for use with existing HDF platforms currently prevalent in our Target European Market and Japan. Our MDHDF filter series incorporates a unique blood-flow architecture that enhances toxin removal with essentially no cost increase over existing devices currently used for HDF therapy.

Laboratory bench studies have been conducted on our OLpur MD190 by members of our research and development staff and by a third party. We completed our initial clinical studies to evaluate the efficacy of our OLpur MD190 as compared to conventional dialyzers in Montpellier, France in 2003. The results from this clinical study support our belief that OLpur MD190 is superior to post-dilution hemodiafiltration using a standard high-flux dialyzer with respect to §2-microglobulin clearance. In addition, clearances of urea, creatinine, and phosphate met the design specifications proposed for the OLpur MD190 device. Furthermore, adverse event data from the study suggest that hemodiafiltration with our OLpur MD190 device was well tolerated by the patients and safe.

We have initiated longer term clinical studies in the United Kingdom, France, Germany, Italy and Spain to further demonstrate the therapeutic benefits of our OLpur MDHDF filter series. A multi-center study was started in March 2005. This study encompassed seven centers in France, five centers in Germany and one center in Sweden. Also commencing in 2005 were studies in the United Kingdom and in Italy. A three-month study was conducted in Spain. All enrolled patients in the multi-center and Spain studies completed the investigational period with the Nephros OLpur MDHDF filter devices. Initial data is very positive, demonstrating improved low-molecular weight protein removal, improvements in appetite, an overall improved distribution of fluids and body composition, and optimal toxin removal and treatment tolerance for patients suffering from limited vascular access. Data was presented at the American Society of Nephrology meeting held in November 2006. A complete manuscript of the entire multi-center study will be submitted for publication in a reputable journal in 2008.

We contracted with TÜV Rheinland of North America, Inc., a worldwide testing and certification agency (also referred to as a notified body) that performs conformity assessments to European Union requirements for medical devices, to assist us in obtaining the Conformité Européene, or CE mark, a mark which demonstrates

4


TABLE OF CONTENTS

compliance with relevant European Union requirements. We received CE marking on the OLpur MD190 (which also covers other dialyzers in our MDHDF filter series), as well as certification of our overall quality system, on July 31, 2003. In the fourth quarter of 2006 we received CE marking on the DSU.

We initiated marketing of our OLpur MD190 in our Target European Market in March 2004, We have established a sales presence in countries throughout our Target European Market, mainly through distributors, and we have developed marketing material in the relevant local languages. We also attend trade shows where we promote our product to several thousand people from the industry. Our OLpur MD220 is a new product that we began selling in our Target European Market in 2006. The OLpur MD220 employs the same technology as our OLpur MD190, but contains a larger surface area of fiber. Because of its larger surface area, the OLpur MD220 may provide greater clearance of certain toxins than the OLpur MD190, and is suitable for patients of larger body mass.

We are currently offering the OLpur MD190 and OLpur MD220 at a price comparable to the existing “high performance” dialyzers sold in the relevant market. We are unable at this time to determine what the market prices will be in the future.

We submitted our original Investigational Device Exemption (“IDE”) application for our OLpur H 2 H hemodiafiltration module and OLpur MD220 filter to the FDA in May 2006. In March 2007, we received approval for our IDE application from the FDA to begin human clinical trials of our OLpur H 2 H hemodiafiltration module and OLpur MD220 hemodiafilter. Following IDE approval, we have obtained approvals from relevant Institutional Review Boards (IRBs) in order to proceed with our clinical trial and began enrolling patients into the study during the fourth quarter 2007. We completed enrollment of study patients in the first quarter of 2008 and anticipate completing the study test period using these ESRD products in the second quarter of 2008.

OLpur HD190

OLpur HD190 is our high-flux dialyzer cartridge, designed for use with either hemodialysis or hemodiafiltration machines. The OLpur HD190 incorporates the same materials as our OLpur MD190, but lacks our proprietary mid-dilution architecture.

OLpur H 2 H

OLpur H 2 H is our add-on module that converts the most common types of hemodialysis machines — that is, those with volumetric ultrafiltration control — into HDF-capable machines allowing them to use our OLpur MDHDF filter. We have completed our OLpur H 2 H design and laboratory bench testing, all of which were conducted by members of our research and development staff. Our design verification of the OLpur H 2 H was completed making the device ready for U.S. clinical trial. In the fourth quarter of 2007, we started treating ESRD patients with the OLpur H 2 H module as part of the U.S. clinical trial, whereby we expect to file 510(k) applications with respect to the OLpur MDHDF filter series and the OLpur H 2 H module in the third quarter of 2008 and hope to achieve U.S. regulatory approval and market introduction of both products during the first half of 2009. We plan to apply for CE marking of our OLpur H 2 H in the third quarter of 2008.

OLpur NS2000

OLpur NS2000 is our standalone HDF machine and associated filter technology, which is in the development stage. We are working with an established dialysis machine manufacturer in Italy to develop the OLpur NS2000 system. The OLpur NS2000 will use the basic platform provided by this manufacturer, but will incorporate our H 2 H technology including our proprietary substitution fluid systems.

We have also designed and developed proprietary substitution fluid filter cartridges for use with the OLpur NS2000, which have been subjected to pre-manufacturing testing. We will need to obtain the relevant regulatory clearances prior to any market introduction of our OLpur NS2000 in our Target European Market or the United States.

Our Water Filtration Product

In January 2006, we introduced our Dual Stage Ultrafilter, or DSU, water filtration system. The DSU incorporates our unique and proprietary dual stage filter architecture. Our research and development work on the OLpur H 2 H and MD filter technologies for ESRD therapy provided the foundations for a proprietary

5


TABLE OF CONTENTS

multi-stage water filter that we believe is cost effective, extremely reliable, and long-lasting. We believe our DSU can offer a robust solution to various contaminated water and infection control issues. The DSU is designed to remove a broad range of bacteria, viral agents and toxic substances, including salmonella, hepatitis, cholera, HIV, Ebola virus, ricin toxin, legionella, fungi and e-coli. We believe our DSU offers four distinct advantages over competitors in the water filtration marketplace:

(1) the DSU is, to our knowledge, the only water filter that provides the user with a simple sight verification that the filter is properly performing its cleansing function due to our unique dual-stage architecture;
(2) the DSU filters finer biological contaminants than other filters of which we are aware in the water filtration marketplace;
(3) the DSU filters relatively large volumes of water before requiring replacement; and
(4) the DSU continues to protect the user even if the flow is reduced by contaminant volumes, because contaminants do not cross the filtration medium.

During January 2006, we received our first purchase order for our DSU from a major hospital in New York City. The hospital conducted an evaluation of our DSUs by installing them in a sampling of the hospital’s patient showers. Upon completion of the first phase, the hospital ordered additional DSU units in December 2006 to continue their evaluation. We are currently in discussions with this and other hospitals regarding potential application of our products as a part of their infection control strategy. With over 5,000 registered hospitals in the United States alone, we believe the hospital shower and faucet market can offer us a valuable opportunity as a first step in water filtration. We have established a goal in 2008 and 2009 to gain a foothold at U.S. and European facilities that seek to become centers of excellence in infection control through the use of our DSU products.

The Defense Department budgets for fiscal 2007 and fiscal 2008 include an aggregate of $3 million in appropriations for the U.S. Marine Corps for development of our dual stage ultra reliable personal water filtration system. We are currently working with military laboratories to define the current project scope and objectives in connection with these appropriations. We have introduced the DSU to various government agencies as one of the solutions of providing potable water in certain emergency response situations. We have begun investigating a range of commercial, industrial and retail opportunities for our DSU technology. We are also currently examining opportunities in India, Africa, Israel and other territories for our DSU technology. We have completed an in-hospital study to demonstrate the efficacy of the DSU, and are currently seeking to publish this study in a relevant publication of substantial distribution.

Our Strategy

We believe that current mortality and morbidity statistics, in combination with quality of life issues faced by the ESRD patient, has generated demand for improved ESRD therapies. We also believe that our products and patented technology offer the ability to remove toxins more effectively than current dialysis therapy, in a cost framework competitive with currently available, less-effective therapies. The following are some highlights of our current strategy:

Showcase Product Efficacy in our Target European Market:   As of March 2004, we initiated marketing in our Target European Market for the OLpur MD190. There is an immediate opportunity for sales of the OLpur MDHDF filters in our Target European Market because there is an established HDF machine base using disposable dialyzers. We have engaged in a series of clinical trials throughout our Target European Market to demonstrate the superior efficacy of our product. We believe that by demonstrating the effectiveness of our MDHDF filter series we will encourage more customers to purchase our products. Our MDHDF filter series has been applied successfully in over 100,000 treatments to date.

Convert Existing Hemodialysis Machines to Hemodiafiltration:   Upon completion of the appropriate documentation for our OLpur H 2 H technology, we plan to apply for CE marking for our OLpur H 2 H during 2008. We plan to complete our regulatory approval processes in the United States for both our OLpur MDHDF filter series and our OLpur H 2 H also in 2008. If successfully approved, our OLpur H 2 H product will enable HDF therapy using the most common types of hemodialysis machines together with our OLpur

TABLE OF CONTENTS

MDHDF filters. Our goal is to achieve market penetration by offering the OLpur H 2 H for use by healthcare providers inexpensively, thus permitting the providers to use the OLpur H 2 H without a large initial capital outlay. We do not expect to generate significant positive margins from sales of OLpur H 2 H. We believe H 2 H will provide a basis for more MDHDF filter sales. We believe that, if approved in 2008, our OLpur H 2 H and MDHDF filters will be the first, and only, HDF therapy available in the United States at that time.

Upgrade Dialysis Clinics to OLpur NS2000:   We believe the introduction of the OLpur NS2000 will represent a further upgrade in performance for dialysis clinics by offering a cost-effective stand-alone HDF solution that incorporates the benefits of our OLpur H 2 H technology. We believe dialysis clinics will entertain OLpur NS2000 as an alternative to their current technology at such dialysis clinic’s machine replacement point.

Develop a Foothold in the Healthcare Arena by Offering our DSU as a Means to Control Environment-Acquired Infections :  We believe our DSU offers an effective, and cost-effective, solution in conquering certain infection control issues faced by hospitals, nursing homes, assisted living facilities and other patient environments where chemical or heat alternatives have typically failed to adequately address the problem. The DSU provides for simple implementation without large capital expenses. We have established a goal in 2008 and 2009 to gain a foothold at U.S. and European facilities that seek to become centers of excellence in infection control through the use of our DSU products. We are also currently examining opportunities in India, Africa, Israel and other territories for our DSU technology.

Pursue our Military Product Development in Conjunction with Value-Adding Partners:   For our military development, we are engaging with strategic allies who offer added value with respect to both new product and marketing opportunities. One of our goals in pursuing this project is to maintain and expand our new product development pipeline and achieve new products suitable for both military and domestic applications.

Explore Complementary Product Opportunities:   Where appropriate, we are also seeking to leverage our technologies and expertise by applying them to new markets. Our H 2 H has potential applications in acute patient care and controlled provision of ultrapure fluids in the field. Our DSU represents a new and complementary product line to our existing ESRD therapy business; we believe the Nephros DSU can offer a robust solution to a broad range of contaminated water and infection control issues.

Manufacturing and Suppliers

We do not intend to manufacture any of our products or components. We have entered into an agreement dated May 12, 2003, and amended on March 22, 2005 with Medica s.r.l., (“Medica”) a developer and manufacturer of medical products with corporate headquarters located in Italy, to assemble and produce our OLpur MD190, MD220 or other filter products at our option. The agreement requires us to purchase from Medica the OLpur MD190s and MD220s or other filter products that we directly market in Europe, or are marketed by our distributor in Italy. In addition, Medica will be given first consideration in good faith for the manufacture of OLpur MD190s, MD220s or other filter products that we do not directly market. No less than semiannually, Medica will provide a report to representatives of both parties to the agreement detailing any technical know-how that Medica has developed that would permit them to manufacture the filter products less expensively and both parties will jointly determine the actions to be taken with respect to these findings. If the fiber wastage with respect to the filter products manufactured in any given year exceeds 5%, then Medica will reimburse us up to half of the cost of the quantity of fiber represented by excess wastage. Medica will manufacture the OLpur MD190 or other filter products in accordance with the quality standards outlined in the agreement. Upon recall of any OLpur MD190 or other filter product due to Medica’s having manufactured one or more products that fail to conform to the required specifications or having failed to manufacture one or more products in accordance with any applicable laws, Medica will be responsible for the cost of recall. The agreement also requires that we maintain certain minimum product-liability insurance coverage and that we indemnify Medica against certain liabilities arising out of our products that they manufacture, providing they do not arise out of Medica’s breach of the agreement, negligence or willful misconduct. The term of the agreement is through May 12, 2009, with successive automatic one-year renewal terms, until either party gives the other notice that it does not wish to renew at least 90 days prior to the end of the term. The agreement may be terminated prior to the end of the term by either party upon the occurrence of certain

TABLE OF CONTENTS

insolvency-related events or breaches by the other party. Although we have no separate agreement with respect to such activities, Medica has also been manufacturing our H 2 H filters and DSU in limited quantities.

We also entered into an agreement in December 2003, and amended in June 2005, with Membrana GmbH (“Membrana”), a manufacturer of medical and technical membranes for applications like dialysis with corporate headquarters located in Germany, to continue to produce the fiber for the OLpur MDHDF filter series. Pursuant to the agreement, Membrana is our exclusive provider of the fiber for the OLpur MDHDF filter series in the European Union as well as certain other territories through September 2009. Notwithstanding the exclusivity provisions, we may purchase membranes from other providers if Membrana is unable to timely satisfy our orders. If and when the volume-discount pricing provisions of our agreement with Membrana become applicable, for each period we will record inventory and cost of goods sold for our fiber requirements pursuant to our agreement with Membrana based on the volume-discounted price level applicable to the actual year-to-date cumulative orders at the end of such period. If, at the end of any subsequent period in the same calendar year, actual year-to-date cumulative orders entitle us to a greater volume-discount for such calendar year, then we will adjust inventory and cumulative cost of goods sold amounts quarterly throughout the calendar year to reflect the greater volume-discount. In August 2006, Membrana awarded us temporary pricing concessions until June 2007. We are currently negotiating with Membrana regarding pricing for purchases incurred from June 2007 to present, as well as future product pricing.

Sales and Marketing

We have established our own sales and marketing organization and distributor network to sell products in our Target European Market and, subject to regulatory approval, intend to establish a similar arrangement in the United States. Our sales and marketing staff has experience in both these geographic areas.

We have established a multi-lingual customer service and financial processing facility in Dublin, Ireland, with multi-lingual customer support available to our customer base in our Target European Market. We have also initiated and completed various clinical studies designed to continue our evaluation of effectiveness of the OLpur MDHDF filters when used on ESRD patients in our Target European Market. These studies are intended to provide us, and have provided us, with valuable information regarding the efficacy of our product and an opportunity to introduce OLpur MDHDF filters to medical institutions in our Target European Market. We have engaged a medical advisor to help us in structuring our clinical study protocols, and to support physicians’ technical inquiries regarding our products.

We are marketing our products primarily to healthcare providers such as hospitals, dialysis clinics, managed care organizations, and nephrology physician groups. We ship our products to these customers both directly from our manufacturer, where this is cost-effective, and through a warehouse facility in the Netherlands. We have engaged, and are in discussions with, product distributors in our Target European Market and major medical device manufacturers/providers in our Target European Market and Japan regarding license and/or distribution opportunities for our technology.

Our New York office oversees sales and marketing activity of our DSU products. We are in discussions with several medical products and filtration products suppliers to act as non-exclusive distributors of our DSU products to medical institutions. For each prospective market for our DSU products we are pursuing alliance opportunities for joint product development and distribution. Our DSU manufacturer in Europe shares certain intellectual property rights with us for one of our DSU designs.

Research and Development

Our research and development efforts continue on several fronts directly related to our current product lines. In particular, in the ESRD therapy domain we are examining ways to enhance further the removal of toxins from the blood by modifying certain blood characteristics. We have applied, and will continue to apply, if and when available, for U.S. government grants in relation to this research, and will apply for further grants as appropriate. We are also working on additional machine devices, next-generation user interface enhancements and other product enhancements.

In the area of water filtration, we have finalized our initial water filtration product line for the healthcare sector and are looking to develop a point-of-use home water filter product for emergency use for example such as when municipal water boil alerts are issued. As part of this development, we will ensure our water

8


TABLE OF CONTENTS

filtration products meet customer needs for various applications. In November 2007, we successfully received a cost contract to perform research for the Office of Naval Research estimated at $866,000 and will be working with the United States Marine Corps Warfighting Laboratory to develop a portable personal water purification system. We will invoice the Office of Naval Research quarterly commencing in March 2008 through the end of the contract period in 2009 for reimbursement of our costs in accordance with the contract. We expect costs to include our internal labor hours worked, material costs incurred, subcontractor costs and our general and administrative expenses, subject to certain limitations. In December 2007, the 2008 U.S. Department of Defense Appropriations Act provided an additional $2 million to continue the development of our dual stage ultra reliable personal water filtration.

To date, we have not engaged any outside engineering, hired any additional personnel or otherwise incurred any material separate research and development expenses specifically allocated to water filtration product development. Our research and development expenditures were primarily related to development expenses associated with the H 2 H machine and salary expense for the fiscal years ended December 31, 2007 and 2006 and were approximately $1,935,000 and $1,844,000, respectively.

Competition

The dialyzer and renal replacement therapy market is subject to intense competition. Accordingly, our future success will depend on our ability to meet the clinical needs of physicians and nephrologists, improve patient outcomes and remain cost-effective for payors.

We compete with other suppliers of ESRD therapies, supplies and services. These suppliers include Fresenius Medical Care AG, and Gambro AB, currently two of the primary machine manufacturers in hemodialysis. At present, Fresenius and Gambro also manufacture HDF machines.

The markets in which we sell our dialysis products are highly competitive. Our competitors in the sale of hemodialysis products include Gambro AB, Baxter International Inc., Asahi Kasei Medical Co. Ltd., Bellco S.p.A., a subsidiary of the Sorin group, B. Braun Melsungen AG, Nipro Corporation Ltd., Nikkiso Co., Ltd., Terumo Corporation and Toray Medical Co., Ltd.

Other competitive considerations include pharmacological and technological advances in preventing the progression of ESRD in high-risk patients such as those with diabetes and hypertension, technological developments by others in the area of dialysis, the development of new medications designed to reduce the incidence of kidney transplant rejection and progress in using kidneys harvested from genetically-engineered animals as a source of transplants.

We are not aware of any other companies using technology similar to ours in the treatment of ESRD. Our competition would increase, however, if companies that currently sell ESRD products, or new companies that enter the market, develop technology that is more efficient than ours. We believe that in order to become competitive in this market, we will need to develop and maintain competitive products and take and hold sufficient market share from our competitors. Therefore, we expect our methods of competing in the ESRD marketplace to include:

continuing our efforts to develop, have manufactured and sell products which, when compared to existing products, perform more efficiently and are available at prices that are acceptable to the market;
displaying our products and providing associated literature at major industry trade shows in the United States, our Target European Market and Asia;
initiating discussions with dialysis clinic medical directors, as well as representatives of dialysis clinical chains, to develop interest in our products;
offering the OLpur H 2 H at a price that does not provide us with significant positive margins in order to encourage adoption of this product and associated demand for our dialyzers; and
pursuing alliance opportunities in certain territories for distribution of our products and possible alternative manufacturing facilities.

TABLE OF CONTENTS

With respect to the water filtration market, we expect to compete with companies that are well entrenched in the water filtration domain. These companies include Pall Corporation, which manufactures end-point water filtration systems, as well as CUNO (a 3M Company) and US Filter (a Siemens business). Our methods of competition in the water filtration domain include:

developing and marketing products that are designed to meet critical and specific customer needs more effectively than competitive devices;
offering unique attributes that illustrate our product reliability, “user-friendliness,” and performance capabilities;
selling products to specific customer groups where our unique product attributes are mission-critical; and
pursuing alliance opportunities for joint product development and distribution.

Intellectual Property

Patents

We protect our technology and products through patents and patent applications. In addition to the United States, we are also applying for patents in other jurisdictions, such as the European Patent Office, Canada and Japan, to the extent we deem appropriate. We have built a portfolio of patents and applications covering our products, including their hardware design and methods of hemodiafiltration.

We believe that our patent strategy will provide a competitive advantage in our target markets, but our patents may not be broad enough to cover our competitors’ products and may be subject to invalidation claims. Our U.S. patents for the “Method and Apparatus for Efficient Hemodiafiltration” and for the “Dual-Stage Filtration Cartridge,” have claims that cover the OLpur MDHDF filter series and the method of hemodiafiltration employed in the operation of the products. Although there are pending applications with claims to the present embodiments of the OLpur H 2 H and the OLpur NS2000 products, these products are still in the development stage and we cannot determine if the applications (or the patents that we may issue on them) will also cover the ultimate commercial embodiment of these products. In addition, technological developments in ESRD therapy could reduce the value of our intellectual property. Any such reduction could be rapid and unanticipated. We have applied for patents on our DSU water filtration products to cover various applications in residential, commercial, and remote environments.

As of January 2008, we have fifteen issued U.S. patents; one issued Eurasian patent; two Mexican patents, two South Korean patents, three Russian patents, four Chinese patents, four French patents, four German patents, four Israeli patents, four Italian patents, one Spanish patent, four United Kingdom patents, one Japanese patent, one Hong Kong patent, and one Canadian patent. Our issued U.S. patents expire between 2018 and 2022. In addition, we have four pending U.S. patent applications, eleven pending patent applications in Canada, eight pending patent applications in the European Patent Office, four pending patent applications in Brazil, one pending patent application in China, fourteen pending patent applications in Japan, two pending patent applications in Mexico, two pending patent applications in South Korea, two pending patent applications in Hong Kong. Our pending patent applications relate to a range of dialysis technologies, including cartridge configurations, cartridge assembly, substitution fluid systems, and methods to enhance toxin removal. We also have pending patent applications on our DSU water filtration system.

Nephros has filed U.S. and International patent applications for a redundant ultra filtration device that was jointly invented by a Nephros employee and an employee of Medica (the manufacturer of certain Nephros products) located in Italy. The companies are negotiating commercial arrangements pertaining to the invention and the patent applications.

Trademarks

As of December 31, 2007, we secured registrations of the trademarks CENTRAPUR, H 2 H, OLpur and the Arrows Logo in the European Union. Applications for these trademarks are pending registration in the United States. We also have applications for registration of a number of other marks pending in the United States Patent and Trademark Office.

TABLE OF CONTENTS

Governmental Regulation

The research and development, manufacturing, promotion, marketing and distribution of our ESRD therapy products in the United States, our Target European Market and other regions of the world are subject to regulation by numerous governmental authorities, including the FDA, the European Union and analogous agencies.

United States

The FDA regulates the manufacture and distribution of medical devices in the United States pursuant to the FDC Act. All of our ESRD therapy products are regulated in the United States as medical devices by the FDA under the FDC Act. Under the FDC Act, medical devices are classified in one of three classes, namely Class I, II or III, on the basis of the controls deemed necessary by the FDA to reasonably ensure their safety and effectiveness.

Class I devices are medical devices for which general controls are deemed sufficient to ensure their safety and effectiveness. General controls include provisions related to (1) labeling, (2) producer registration, (3) defect notification, (4) records and reports and (5) quality service requirements, or QSR.
Class II devices are medical devices for which the general controls for the Class I devices are deemed not sufficient to ensure their safety and effectiveness and require special controls in addition to the general controls. Special controls include provisions related to (1) performance and design standards, (2) post-market surveillance, (3) patient registries and (4) the use of FDA guidelines.
Class III devices are the most regulated medical devices and are generally limited to devices that support or sustain human life or are of substantial importance in preventing impairment of human health or present a potential, unreasonable risk of illness or injury. Pre-market
approval by the FDA is the required process of scientific review to ensure the safety and effectiveness of Class III devices.

Before a new medical device can be introduced to the market, FDA clearance of a pre-market notification under Section 510(k) of the FDC Act or FDA clearance of a pre-market approval, or PMA, application under Section 515 of the FDC Act must be obtained. A Section 510(k) clearance will be granted if the submitted information establishes that the proposed device is “substantially equivalent” to a legally marketed Class I or Class II medical device or to a Class III medical device for which the FDA has not called for pre-market approval under Section 515. The Section 510(k) pre-market clearance process is generally faster and simpler than the Section 515 pre-market approval process. We understand that it generally takes four to 12 months from the date a Section 510(k) notification is accepted for filing to obtain Section 510(k) pre-market clearance and that it could take several years from the date a Section 515 application is accepted for filing to obtain Section 515 pre-market approval, although it may take longer in both cases.

We expect that all of our ESRD therapy products will be categorized as Class II devices and that these products will not require clearance of pre-market approval applications under Section 515 of the FDC Act, but will be eligible for marketing clearance through the pre-market notification process under Section 510(k). We have determined that we are eligible to utilize the Section 510(k) pre-market notification process based upon our ESRD therapy products’ substantial equivalence to previously legally marketed devices in the United States. However, we cannot assure you:

that we will not need to reevaluate the applicability of the Section 510(k) pre-market notification process to our ESRD therapy products in the future;
that the FDA will agree with our determination that we are eligible to use the Section 510(k) pre-market notification process; or
that the FDA will not in the future require us to submit a Section 515 pre-market approval application, which would be a more costly, lengthy and uncertain approval process.

11


TABLE OF CONTENTS

The FDA has recently been requiring a more rigorous demonstration of substantial equivalence than in the past and may request clinical data to support pre-market clearance. As a result, the FDA could refuse to accept for filing a Section 510(k) notification made by us or request the submission of additional information. The FDA may determine that any one of our proposed ESRD therapy products is not substantially equivalent to a legally marketed device or that additional information is needed before a substantial equivalence determination can be made. A “not substantially equivalent” determination, or request for additional data, could prevent or delay the market introduction of our products that fall into this category, which in turn could have a material adverse effect on our potential sales and revenues. Moreover, even if the FDA does clear one or all of our products under the Section 510(k) process, it may clear a product for some procedures but not others or for certain classes of patients and not others.

For any devices cleared through the Section 510(k) process, modifications or enhancements that could significantly affect the safety or effectiveness of the device or that constitute a major change to the intended use of the device will require a new Section 510(k) pre-market notification submission. Accordingly, if we do obtain Section 510(k) pre-market clearance for any of our ESRD therapy products, we will need to submit another Section 510(k) pre-market notification if we significantly affect that product’s safety or effectiveness through subsequent modifications or enhancements.

If human clinical trials of a device are required in connection with a Section 510(k) notification and the device presents a “significant risk,” the sponsor of the trial (usually the manufacturer or distributor of the device) will need to file an Investigational Device Exemption, or IDE, application prior to commencing human clinical trials. The IDE application must be supported by data, typically including the results of animal testing and/or laboratory bench testing. If the IDE application is approved, human clinical trials may begin at a specific number of investigational sites with a specific number of patients, as specified in the IDE. Sponsors of clinical trials are permitted to sell those devices distributed in the course of the study provided such compensation does not exceed recovery of the costs of manufacture, research, development and handling. An IDE supplement must be submitted to the FDA before a sponsor or investigator may make a change to the investigational plan that may affect its scientific soundness or the rights, safety or welfare of subjects. We submitted our original IDE application to the FDA for our OLpur H 2 H hemodiafiltration module and OLpur MD220 filter in May 2006. The FDA answered our application with additional questions in June 2006, and we submitted responses to the FDA questions in December 2006. In January 2007, we received conditional approval for our IDE application from the FDA to begin human clinical trials of our OLpur H 2 H hemodiafiltration module and OLpur MD220 hemodiafilter. In March 2007, we received full approval on our IDE application from the FDA to begin human clinical trials of our OLpur H 2 H hemodiafiltration module and OLpur MD220 hemodiafilter. We have obtained approval from the IRBs and have commenced the clinical trial. At year end 2007, 50% of the needed study patients had been enrolled in the study and were being treated three times per week on the Nephros devices. The remaining patients were enrolled in the first quarter of 2008, and we anticipate that all study treatments with the Nephros devices will be completed by end of the second quarter of 2008. We expect to file 510(k) applications with respect to the OLpur MDHDF filter series and the OLpur H 2 H module in the third quarter of 2008 and hope to achieve U.S. regulatory approval of both products during the first half of 2009. We plan to apply for CE marking of our OLpur H 2 H in the third quarter of 2008.

The Section 510(k) pre-market clearance process can be lengthy and uncertain. It will require substantial commitments of our financial resources and management’s time and effort. Significant delays in this process could occur as a result of factors including:

our inability to timely raise sufficient funds;
the FDA’s failure to schedule advisory review panels;
changes in established review guidelines;
changes in regulations or administrative interpretations; or
determinations by the FDA that clinical data collected is insufficient to support the safety and effectiveness of one or more of our products for their intended uses or that the data warrants the continuation of clinical studies.

12


TABLE OF CONTENTS

Delays in obtaining, or failure to obtain, requisite regulatory approvals or clearances in the United States for any of our products would prevent us from selling those products in the United States and would impair our ability to generate funds from sales of those products in the United States, which in turn could have a material adverse effect on our business, financial condition, and results of operations.

The FDC Act requires that medical devices be manufactured in accordance with the FDA’s current QSR regulations which require, among other things, that:

the design and manufacturing processes be regulated and controlled by the use of written procedures;
the ability to produce medical devices which meet the manufacturer’s specifications be validated by extensive and detailed testing of every aspect of the process;
any deficiencies in the manufacturing process or in the products produced be investigated;
detailed records be kept and a corrective and preventative action plan be in place; and
manufacturing facilities be subject to FDA inspection on a periodic basis to monitor compliance with QSR regulations.

If violations of the applicable QSR regulations are noted during FDA inspections of our manufacturing facilities or the manufacturing facilities of our contract manufacturers, there may be a material adverse effect on our ability to produce and sell our products.

Before the FDA approves a Section 510(k) pre-market notification, the FDA is likely to inspect the relevant manufacturing facilities and processes to ensure their continued compliance with QSR. Although some of the manufacturing facilities and processes that we expect to use to manufacture our OLpur MDHDF filters and OLpur NS2000 have been inspected and certified by a worldwide testing and certification agency (also referred to as a notified body) that performs conformity assessments to European Union requirements for medical devices, they have not all been inspected by the FDA. Similarly, although some of the facilities and processes that we expect to use to manufacture our OLpur H 2 H have been inspected by the FDA, they have not all been inspected by any notified body. A “notified body” is a group accredited and monitored by governmental agencies that inspects manufacturing facilities and quality control systems at regular intervals and is authorized to carry out unannounced inspections. Even after the FDA has cleared a Section 510(k) submission, it will periodically inspect the manufacturing facilities and processes for compliance with QSR. In addition, in the event that additional manufacturing sites are added or manufacturing processes are changed, such new facilities and processes are also subject to FDA inspection for compliance with QSR. The manufacturing facilities and processes that will be used to manufacture our products have not yet been inspected by the FDA for compliance with QSR. We cannot assure you that the facilities and processes used by us will be found to comply with QSR and there is a risk that clearance or approval will, therefore, be delayed by the FDA until such compliance is achieved.

In addition to the requirements described above, the FDC Act requires that:

all medical device manufacturers and distributors register with the FDA annually and provide the FDA with a list of those medical devices which they distribute commercially;
information be provided to the FDA on death or serious injuries alleged to have been associated with the use of the products, as well as product malfunctions that would likely cause or contribute to death or serious injury if the malfunction were to recur; and
certain medical devices not cleared with the FDA for marketing in the United States meet specific requirements before they are exported.

European Union

The European Union began to harmonize national regulations comprehensively for the control of medical devices in member nations in 1993, when it adopted its Medical Devices Directive 93/42/EEC. The European Union directive applies to both the manufacturer’s quality assurance system and the product’s technical design and discusses the various ways to obtain approval of a device (dependent on device classification), how to

13


TABLE OF CONTENTS

properly CE Mark a device and how to place a device on the market. We have subjected our entire business in our Target European Market to the most comprehensive procedural approach in order to demonstrate the quality standards and performance of our operations, which we believe is also the fastest way to launch a new product in the European Community.

The regulatory approach necessary to demonstrate to the European Union that the organization has the ability to provide medical devices and related services that consistently meet customer requirements and regulatory requirements applicable to medical devices requires the certification of a full quality management system by a notified body. We engaged TÜV Rheinland of North America, Inc. (“TÜV Rheinland”) as the notified body to assist us in obtaining certification to the International Organization for Standardization (“ISO”) 13485/2003 standard, which demonstrates the presence of a quality management system that can be used by an organization for design and development, production, installation and servicing of medical devices and the design, development and provision of related services.

European Union requirements for products are set forth in harmonized European Union standards and include conformity to safety requirements, physical and biological properties, construction and environmental properties, and information supplied by the manufacturer. A company demonstrates conformity to these requirements, with respect to a product, by pre-clinical tests, biocompatibility tests, qualification of products and packaging, risk analysis and well-conducted clinical investigations approved by ethics committees.

Once a manufacturer’s full quality management system is determined to be in compliance with ISO 13485/2003 and other statutory requirements, and the manufacturer’s products conform with harmonized European standards, the notified body will recommend and document such conformity. The manufacturer will receive a CE marking and ISO certifications, and then may place a CE mark on the relevant products. The CE mark, which stands for Conformité Européenne, demonstrates compliance with the relevant European Union requirements. Products subject to these provisions that do not bear the CE mark cannot be imported to, or sold or distributed within, the European Union.

In July 2003, we received a certification from TÜV Rheinland that our quality management system conforms with the requirements of the European Community. At the same time, TÜV Rheinland approved our use of the CE marking with respect to the design and production of high permeability hemodialyzer products for ESRD therapy. As of the date of filing of this Annual Report, the manufacturing facilities and processes that we are using to manufacture our OLpur MDHDF filter series have been inspected and certified by a notified body.

Regulatory Authorities in Regions Outside of the United States and the European Union

We also plan to sell our ESRD therapy products in foreign markets outside the United States which are not part of the European Union. Requirements pertaining to medical devices vary widely from country to country, ranging from no health regulations to detailed submissions such as those required by the FDA. We believe the extent and complexity of regulations for medical devices such as those produced by us are increasing worldwide. We anticipate that this trend will continue and that the cost and time required to obtain approval to market in any given country will increase, with no assurance that such approval will be obtained. Our ability to export into other countries may require compliance with ISO 13485, which is analogous to compliance with the FDA’s QSR requirements. Other than the CE marking of our OLpur MDHDF filter products, we have not obtained any regulatory approvals to sell any of our products and there is no assurance that any such clearance or certification will be issued.

Reimbursement

In both domestic markets and markets outside of the United States, sales of our ESRD therapy products will depend in part, on the availability of reimbursement from third-party payors. In the United States, ESRD providers are reimbursed through Medicare, Medicaid and private insurers. In countries other than the United States, ESRD providers are also reimbursed through governmental and private insurers. In countries other than the United States, the pricing and profitability of our products generally will be subject to government controls. Despite the continually expanding influence of the European Union, national healthcare systems in its member nations, reimbursement decision-making included, are neither regulated nor integrated at the European Union level. Each country has its own system, often closely protected by its corresponding national government.

Product Liability and Insurance

The production, marketing and sale of kidney dialysis products have an inherent risk of liability in the event of product failure or claim of harm caused by product operation. We have acquired product liability insurance for our OLpur MDHDF filter products in the amount of $5 million. A successful claim in excess of our insurance coverage could materially deplete our assets. Moreover, any claim against us could generate negative publicity, which could decrease the demand for our products, our ability to generate revenues and our profitability.

Some of our existing and potential agreements with manufacturers of our products and components of our products do or may require us (1) to obtain product liability insurance or (2) to indemnify manufacturers against liabilities resulting from the sale of our products. If we are not able to maintain adequate product liability insurance, we will be in breach of these agreements, which could materially adversely affect our ability to produce our products. Even if we are able to obtain and maintain product liability insurance, if a successful claim in excess of our insurance coverage is made, then we may have to indemnify some or all of our manufacturers for their losses, which could materially deplete our assets.

Employees

As of December 31, 2007, we employed a total of 13 employees, 11 of whom were full time and 2 who are employed on a part-time basis. Of the 13 total employees, 3 were employed in a marketing/clinical support capacity, 4 in general and administrative and 6 in research and development.

Recent Developments

In March 2007, we received full approval on our IDE application from the FDA to begin human clinical trials of our OLpur H 2 H hemodiafiltration module and OLpur MD220 hemodiafilter. We have obtained approval from the IRBs and have commenced the clinical trial. At years end, 50% of the needed study patients had been enrolled in the study and were being treated three times per week on the Nephros devices. The remaining patients were enrolled in the first quarter of 2008, and we anticipate that all study treatments with the Nephros devices will be completed by end of the second quarter of 2008.

Item 2. Description of Property

Our U.S. facilities are located at 3960 Broadway, 4th Floor, New York, New York 10032 and consist of approximately 2,788 square feet of space. As of September 30, 2007, we renewed our rental agreement for the use of this space with the Trustees of Columbia University in the City of New York. The term of the rental agreement is for one year with a monthly cost of approximately $14,000, including monthly internet access. We use our facilities to house our corporate headquarters and research facilities. Our offices and laboratories are housed in the Audubon Business and Technology Center administered by Columbia University, which is equipped to accommodate biotechnology and medical product development companies. Of the space we rent from Columbia University, approximately 1,610 square feet is dedicated laboratory space, which is equipped with laboratory equipment, such as benches, fume hoods, gas, air and water systems, and the remaining 1,178 square feet is dedicated office space.

Our facilities in our Target European Market are located at Suite 19, 25-26 Windsor Place, Lower Pembroke St, Dublin 2, Ireland and consist of approximately 500 square feet of space. On August 3, 2006 we entered into a lease for this space with Leeson Business Centres. The lease is automatically prolonged until either party gives a three-month termination notice and, as of December 31, 2007, we are operating with a current monthly cost of 3,000 Euro per month ($4,410, approximately). We use our facilities to house our accounting, operations and customer service departments. Windsor Place is a modern office complex in the heart of downtown Dublin. We believe this space is currently adequate to meet our needs. We do not own any real property for use in our operations or otherwise.

Item 3. Legal Proceedings

There is no currently pending legal proceeding and, as far as we are aware, no governmental authority is contemplating any proceeding to which we are a party or to which any of our properties is subject.

We have neither paid nor declared dividends on our common stock since our inception and do not plan to pay dividends on our common stock in the foreseeable future. We expect that any earnings which we may realize will be retained to finance our growth. There can be no assurance that we will ever pay dividends on our common stock. Our dividend policy with respect to the common stock is within the discretion of the Board of Directors and its policy with respect to dividends in the future will depend on numerous factors, including our earnings, financial requirements and general business conditions.

The information set forth in Part III, Item 11 of this Annual Report on Form 10-KSB relating to our equity compensation plans is hereby incorporated by reference to this Item 5.

Item 6. Management’s Discussion and Analysis or Plan of Operation

Business Overview

Since our inception in April 1997, we have been engaged primarily in the development of hemodiafiltration, or HDF, products and technologies for treating patients with End Stage Renal Disease, or ESRD. Our products include the OLpur MD190 and MD220, which are dialyzers (our “OLpur MDHDF Filter Series”), OLpur H 2 H, an add-on module designed to enable HDF therapy using the most common types of hemodialysis machines, and the OLpur NS2000 system, a stand-alone HDF machine with associated filter technology. We began selling our OLpur MD190 dialyzer in some parts of our Target European Market (consisting of France, Germany, Ireland, Italy and the United Kingdom (U.K.), as well as Cyprus, Denmark, Greece, the Netherlands, Norway, Portugal, Spain, Sweden and Switzerland) in March 2004, and have developed units suitable for clinical evaluation for our OLpur H 2 H product. We are developing our OLpur NS2000 product in conjunction with an established machine manufacturer in Italy. We are working with this manufacturer to modify an existing HDF platform they currently offer for sale in parts of our Target European Market, incorporating our proprietary H 2 H technology.

To date, we have devoted most of our efforts to research, clinical development, seeking regulatory approval for our ESRD products, establishing manufacturing and marketing relationships and establishing our own marketing and sales support staff for the development, production and sale of our ESRD therapy products in our Target European Market and the United States upon their approval by appropriate regulatory authorities.

In the first quarter of 2007, we received approval from the U.S. Food and Drug Administration (the “FDA”) for our Investigational Device Exemption (“IDE”) application for the clinical evaluation of our OLpur H 2 H module and OLpur MD 220 filter. We have also received the approval from the Institutional Review Board (“IRB”) associated with the clinics at which the trials will take place. We have obtained approval from Western IRB, Inc. which enables us to proceed with our clinical trial. We began our clinical

trials at the beginning of the fourth quarter of 2007. At year end 2007, 50% of the needed study patients had been enrolled in the study and were being treated three times per week on the Nephros devices. The remaining patients were enrolled in the first quarter of 2008. We have targeted submitting our data to the FDA with our 510(k) application on these products by the third quarter of 2008. We also plan to apply for CE marking in Europe for our OLpur H 2 H during the course of our clinical trial.

We have also applied our filtration technologies to water filtration and in 2006 we introduced our new Dual Stage Ultrafilter (the “DSU”) water filtration system. Our DSU represents a new and complementary product line to our existing ESRD therapy business. The DSU incorporates our unique and proprietary dual stage filter architecture and is, to our knowledge, the only water filter that allows the user to sight-verify that the filter is properly performing its cleansing function. The DSU is designed to remove a broad range of bacteria, viral agents and toxic substances, including salmonella, hepatitis, cholera, HIV, Ebola virus, ricin toxin, legionella, fungi and e-coli.

We fulfilled two purchase orders for our DSU to a major medical center in New York City in 2006. In 2007, this NYC medical center extended the terms of our joint evaluation agreement and we are working with their representatives on certain specifications for a customized DSU to meet their requirements. We have begun a multi-hospital study to demonstrate the efficacy of the DSU. Our goal is to publish this study in 2008 in a relevant publication of substantial distribution. We are planning to pursue additional sales of our DSU upon completion of planned improvements in product ergonomics.

In 2006, the U.S. Defense Department budget included an appropriation for the U.S. Marine Corps for development of a dual stage water ultra filter. In connection with this Federal appropriation totaling $1 million, we expect to work with the U.S. Marine Corps in developing a personal potable water purification system for warfighters. In December 2007,the U.S. Department of Defense Appropriations Act provided an additional $2 million to continue the development of our dual stage ultra reliable personal water filtration system.

Since our inception, we have incurred annual net losses. As of December 31, 2007, we had an accumulated deficit of approximately $81,612,000, and we expect to incur additional losses in the foreseeable future. We recognized net losses of approximately $26,356,000 for the year ended December 31, 2007, and approximately $8,013,000 for the year ended December 31, 2006.

Since our inception, we have financed our operations primarily through sales of our equity and debt securities. From inception through December 31, 2007, we received net offering proceeds from private sales of equity and debt securities and from the initial public offering of our common stock (after deducting underwriters’ discounts, commissions and expenses, and our offering expenses) of approximately $52.0 million in the aggregate. An additional source of finances was our license agreement with Asahi, pursuant to which we received an up front license fee of $1.75 million in March 2005.

During January 2006, we received our first purchase order for our DSU from a major hospital in New York City. The hospital conducted an evaluation of our DSUs by installing them in a sampling of the hospital’s patient showers. Upon completion of the first phase, the hospital ordered additional DSU units in December 2006, which we fulfilled, to continue its evaluation. We are in discussion with this hospital in connection with their adoption of the DSU as part of their water filtration system. These initial DSU sales did not result in material net revenues. We are pursuing a larger multi-hospital study to demonstrate the efficacy of the DSU. Our goal is to publish this study in 2008 in a relevant publication of substantial distribution.

The following trends, events and uncertainties may have a material impact on our potential sales, revenue and income from operations:

(1) the completion and success of additional clinical trials and of our regulatory approval processes for each of our ESRD therapy products in our target territories;
(2) the market acceptance of HDF therapy in the United States and of our technologies and products in each of our target markets;
(3) our ability to effectively and efficiently manufacture, market and distribute our products;

18


TABLE OF CONTENTS

(4) our ability to sell our products at competitive prices which exceed our per unit costs; and
(5) the consolidation of dialysis clinics into larger clinical groups.

To the extent we are unable to succeed in accomplishing (1) through (4), our sales could be lower than expected and dramatically impair our ability to generate income from operations. With respect to (5), the impact could either be positive, in the case where dialysis clinics consolidate into independent chains, or negative, in the case where competitors acquire these dialysis clinics and use their own products, as competitors have historically tended to use their own products in clinics they have acquired.

Regaining Compliance with AMEX’s Continued Listing Standards

During 2006, we received notices from AMEX that we were not in compliance with certain conditions of the continued listing standards of Section 1003 of the AMEX Company Guide. Specifically, AMEX noted our failure to comply with Section 1003(a)(i) of the AMEX Company Guide relating to shareholders’ equity of less than $2,000,000 and losses from continuing operations and/or net losses in two out of our three most recent fiscal years; Section 1003(a)(ii) of the AMEX Company Guide relating to shareholders’ equity of less than $4,000,000 and losses from continuing operations and/or net losses in three out of our four most recent fiscal years; and Section 1003(a)(iii) of the AMEX Company Guide relating to shareholders’ equity of less than $6,000,000 and losses from continuing operations and/or net losses in our five most recent fiscal years. We submitted a plan in August 2006 to advise AMEX of the steps we had taken, and proposed to take, to regain compliance with the applicable listing standards.

On November 14, 2006, we received notice that the AMEX staff had reviewed our plan of compliance to meet the AMEX’s continued listing standards and that AMEX would continue our listing while we sought to regain compliance with the continued listing standards during the period ending January 17, 2008. During the plan period, we were required to provide the AMEX staff with updates regarding initiatives set forth in our plan of compliance. On November 14, 2007, all of our Series A 10% Secured Convertible Notes Due 2008 and our Series B 10% Secured Convertible Notes due 2008 (collectively, the “ Notes ”), representing an aggregate principal amount of $18 million, were converted into shares of our common stock and warrants, resulting in an increase in our stockholders’ equity. As a result, and notwithstanding our loss during the fourth quarter of 2007, our stockholders’ equity, at December 31, 2007, was approximately $8,756,000 and in excess of the $6,000,000 required by the AMEX rules.

On March 5, 2008, we received a letter from the AMEX acknowledging that we had resolved the continued listing deficiencies referenced in the AMEX’s letters dated July 17, 2006 and November 14, 2006. However, if we are not able to generate revenues from operations or timely raise equity capital, we are likely to again fail to comply with the AMEX rules regarding minimum shareholders’ equity. Should this occur within 12 months of January 17, 2009, then, in accordance with Section 1009(h) of the AMEX Company Guide, the AMEX may evaluate the relationship between the two incidents and apply more truncated procedures for compliance or immediately initiate delisting proceedings. Furthermore, there can be no assurance that we will not run afoul of the AMEX’s other continued listing standards. If we fail to meet such standards, then our common stock may be delisted from the AMEX.

On September 27, 2007, we received a warning letter from the AMEX stating that the staff of the AMEX Listing Qualifications Department had determined that we were not in compliance with Section 121B(2)(c) of the AMEX Company Guide requiring that at least 50% of the directors of our board of directors are independent directors. This non-compliance was due to the fact that William J. Fox, Judy Slotkin, W. Townsend Ziebold and Howard Davis resigned from our board of directors on September 19, 2007, concurrently with the appointment of Paul Mieyal and Arthur Amron to our board of directors, in accordance with our September 2007 financing. Consequently, our board of directors consisted of five directors, two of whom were independent. The AMEX had given us until December 26, 2007 to regain compliance with the independence require- ments. On November 16, 2007, James S. Scibetta was appointed to serve as an independent director on our board of directors. On December 5, 2007 we received a letter from the AMEX acknowledging that we had resolved the continued listing deficiency identified in their September 27, 2007 letter.

Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157, “ Fair Value Measurements ” (“SFAS 157”), which applies whenever other standards require (or permit) assets or liabilities to be measured at fair value. SFAS 157 established a fair value hierarchy that prioritizes the information used to develop the assumption that market participants would use when pricing an asset or liability. SFAS 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. We are currently evaluating the impact of adopting SFAS 157 on our financial position, cash flows, and results of operations.

In February 2007, the FASB issued SFAS No. 159, “ The Fair Value Option for Financial Assets and Financial Liabilities ” (“SFAS 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. SFAS 159 will be effective for the fiscal years beginning after November 15, 2007. We are currently evaluating the impact of adopting SFAS 159 on our financial position, cash flows, and results of operations.

In December 2007, the FASB issued SFAS No. 141 (Revised 2007) “ Business Combinations ” (“SFAS 141R”), which requires the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction; establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed; and requires the acquirer to disclose to investors, and other users, all of the information they need to evaluate and understand the nature and financial effect of the business combination. SFAS 141R will be effective for acquisitions with a date on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. We are currently evaluating the impact of adopting SFAS 141R on our financial position, cash flows, and results of operations.

In December 2007, the FASB issued SFAS No. 160 “ Noncontrolling Interests in Consolidated Financial Statements-an Amendment of ARB No. 51 ” (“SFAS 160”), which requires the recognition of a noncontrolling interest (minority interest) as equity in the consolidated financial statements and separate from the parent’s equity; the inclusion of the amount of net income attributable to the noncontrolling interest in consolidated income on the face of the income statement; and a parent recognize a gain or loss in net income when a subsidiary is deconsolidated. SFAS 160 will be effective for the fiscal years beginning on or after December 15, 2008. We are currently evaluating the impact of adopting SFAS 160 on our financial position, cash flows, and results of operations.

In December 2007, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 110 (“SAB 110”). SAB 110 was effective January 1, 2008 and expresses the views of the Staff of the SEC regarding the use of the simplified method, as discussed in SAB No. 107, in developing an estimate of the expected term of “plain vanilla” share options in accordance with SFAS No. 123R. We are currently evaluating the impact of applying the provisions of SAB 110 on our financial position and results of operations.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of financial statements in accordance with generally accepted accounting principles in the United States requires application of management’s subjective judgments, often requiring the need to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods. Our actual results may differ substantially from these estimates under different assumptions or conditions. While our significant accounting policies are described in more detail in the notes to consolidated financial statements included in this annual report on Form 10-KSB, we believe that the following accounting policies require the application of significant judgments and estimates.

Revenue Recognition

Revenue is recognized in accordance with Securities and Exchange Commission Staff Accounting Bulletin, or SAB, No. 104 Revenue Recognition. SAB No. 104 requires that four basic criteria must be met before revenue can be recognized: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed and determinable; and (iv) collectibility is reasonably assured.

Stock-Based Compensation

We have adopted SFAS 123R, effective January 1, 2006. SFAS 123R requires the recognition of compensation expense in an amount equal to the fair value of all share-based payments granted to employees. We have elected the modified prospective transition method and therefore adjustments to prior periods are not required as a result of adopting SFAS 123R. Under this method, the provisions of SFAS 123R apply to all awards granted after the date of adoption and to any unrecognized expense of awards unvested at the date of adoption based on the grant date fair value. SFAS 123R also amends SFAS No. 95, “Statement of Cash Flows,” to require that excess tax benefits that had been reflected as operating cash flows be reflected as financing cash flows.

Prior to our initial public offering, options were granted to employees, non-employees and non-employee directors at exercise prices which were lower than the fair market value of our stock on the date of grant. After the date of our initial public offering, stock options are granted to employees, non-employees and non-employee directors at exercise prices equal to the fair market value of our stock on the date of grant. Stock options granted have a life of 10 years and vest upon a combination of the following: immediate vesting; straight line vesting of two, three, or four years; and upon the achievement of certain milestones.

Accounts Receivable

We provide credit terms to our customers in connection with purchases of the our products. We periodically review customer account activity in order to assess the adequacy of the allowances provided for potential collection issues and returns. Factors considered include economic conditions, each customer’s payment and return history and credit worthiness. Adjustments, if any, are made to reserve balances following the completion of these reviews to reflect our best estimate of potential losses.

Inventory Reserves

Our inventory reserve requirements are based on factors including the products’ expiration date and estimates for the future sales of the product. If estimated sales levels do not materialize, we will make adjustments to its assumptions for inventory reserve requirements.

Accrued Expenses

We are required to estimate accrued expenses as part of our process of preparing financial statements. This process involves identifying services which have been performed on our behalf, and the level of service performed and the associated cost incurred for such service as of each balance sheet date in our financial statements. Examples of areas in which subjective judgments may be required include costs associated with services provided by contract organizations for the preclinical development of our products, the manufacturing of clinical materials, and clinical trials, as well as legal and accounting services provided by professional organizations. In connection with such service fees, our estimates are most affected by our understanding of the status and timing of services provided relative to the actual levels of services incurred by such service providers. The majority of our service providers invoice us monthly in arrears for services performed. In the event that we do not identify certain costs, which have begun to be incurred, or we under- or over-estimate the level of services performed or the costs of such services, our reported expenses for such period would be too low or too high. The date on which certain services commence, the level of services performed on or before a given date and the cost of such services are often determined based on subjective judgments. We make these judgments based upon the facts and circumstances known to us in accordance with generally accepted accounting principles.

Results of Operations

Fluctuations in Operating Results

Our results of operations have fluctuated significantly from period to period in the past and are likely to continue to do so in the future. We anticipate that our annual results of operations will be impacted for the foreseeable future by several factors including the progress and timing of expenditures related to our research and development efforts, marketing expenses related to product launches, timing of regulatory approval of our various products and market acceptance of our products. Due to these fluctuations, we believe that the period to period comparisons of our operating results are not a good indication of our future performance.

The Fiscal Year Ended December 31, 2007 Compared to the Fiscal Year Ended December 31, 2006

Revenues

Total revenues for the fiscal year ended December 31, 2007 were approximately $1,196,000 compared to approximately $794,000 for the fiscal year ended December 31, 2006. Total product revenues increased approximately $402,000, an increase of almost 51% ascribed to the following factors; 27% increase due to increased unit sales in our Target European Market, 12% due to the impact to favorable currency translation factors, 7% increase in average realized selling prices in our Target European Market and 7% for the impact of a $52,000 adjustment in the fiscal year ended December 31, 2007 to the returns reserve. These factors are partially offset by 3% for the impact of no sales of the DSU product in the US market for the fiscal year ended December 31, 2007. The increased unit sales of our OLpur MDHDF filter series product is in our Target European Market; units sales increased by 9,216 as total units sold increased to 44,000 in the fiscal year ended December 31, 2007 from 34,784 fiscal year ended December 31, 2006. Our DSU product was introduced in January 2006 and contributed approximately $21,000 to sales that fiscal year.

Cost of Goods Sold

Cost of goods sold was approximately $876,000 for the twelve months ended December 31, 2007 from approximately $944,000 for the twelve months ended December 31, 2006. The $68,000 decrease in cost of goods sold is primarily due to lower expenses associated with inventory adjustments of approximately $242,000 being partially offset by approximately $174,000 in increased costs associated with greater sales volumes.

Inventory adjustments for the twelve months ended December 31, 2007 were approximately $82,000 compared to approximately $324,000 in adjustments in the twelve months ended December 31, 2006; a decrease of $242,000. The adjustments for the twelve months ended December 31, 2006 relate to a write-off of expired inventory of $160,000 and a revaluation of specific inventory lots to reflect the competitive pricing environment in the German market of $164,000. The inventory adjustments for the twelve months ended December 31, 2007 of $82,000 relate entirely to write-off of expired or near expiry rework product. Improved product requirement forecasting resulting from better communication with our primary distributor minimizes the likelihood of inventory adjustments of this nature in the future.

The $174,000 in increased costs associated with greater sales volumes is primarily due to approximately $112,000 ascribed to greater unit sales in our Target European Market and $67,000 due to the impact of currency translation factors being partially offset by approximately $5,000 for other miscellaneous factors.

Research and Development

Research and development expenses were approximately $1,935,000 for the twelve months ended December 31, 2007 compared to approximately $1,844,000 for the twelve months ended December 31, 2006, an increase of approximately $91,000 or almost 5%. The increase is primarily due to increased compensation expense of approximately $375,000 and increased clinical trial expense of approximately $338,000 being partially offset by lower expenses for development and testing of approximately $602,000. The increase in compensation expense of approximately $375,000 is due to higher salary expense of approximately $178,000 and higher deferred compensation expense of approximately $197,000. Lower expense for development and testing is ascribed to lower machine development expenses of approximately $298,000 and lower expenses for outside testing of approximately $132,000. The lower machine development expense is due to the OLpur H 2 H product’s engineering phase approaching completion with fewer contract hours required to be logged by our outside developers during the twelve months ended December 31, 2007.

Depreciation Expense

Depreciation expense was approximately $337,000, for the twelve months ended December 31, 2007 compared to approximately $319,000 for the twelve months ended December 31, 2006, an increase of 6%. The $18,000 increase is primarily due to the impact of currency translation factors of approximately $24,000 and other miscellaneous factors impacting the twelve months ended December 31, 2007 of approximately $8,000, which are partially offset by a credit to depreciation expense in fiscal 2006 of approximately $14,000 to correct an overstatement of accumulated depreciation in the calculations for fiscal 2005.

Selling, General and Administrative Expenses

Selling, general and administrative expenses were approximately $5,527,000 for the twelve months ended December 31, 2007 compared to approximately $5,719,000 for the twelve months ended December 31, 2006, a decrease of approximately $192,000 or 3%. The decrease reflects lower selling expenses of approximately $926,000 being partially offset by higher general and administrative expenses of approximately $734,000.

Selling expenses were approximately $451,000 for the twelve months ended December 31, 2007 compared to approximately $1,377,000 the twelve months ended December 31, 2006, a decrease of approximately $926,000; almost 67%. This decrease is primarily due to lower compensation expense of approximately $414,000, lower spending on travel and entertainment expenses of approximately $220,000, lower spending on trade show expenses of approximately $191,000 and other reductions totaling approximately $101,000. The total decrease in expense reflects management’s strategy to focus European selling and marketing though our European distributor.

General and administrative expenses were approximately $5,076,000 for the twelve months ended December 31, 2007 compared to approximately $4,342,000 for the twelve months ended December 31, 2006 an increase of approximately $734,000 primarily due to factors impacting professional service fees and compensation expense.

Compensation expenses were approximately $2,352,000 for the twelve months ended December 31, 2007 compared to approximately $1,825,000 the twelve months ended December 31, 2006. The increase of approximately $527,000 or almost 29% is primarily due to an increase in US compensation of approximately $611,000 being partially offset by a reduction in European compensation of approximately $84,000. The US increase in the twelve months ended December 31, 2007 is attributable to an increase in deferred compensation expense for stock options of approximately $213,000, an increase in severance expense of approximately $154,000, an increase of bonus expense of approximately $100,000, an increase of US salary expense of approximately $88,000 and an increase of other miscellaneous factors totaling approximately $46,000. The decrease in European expenses of approximately $84,000 is primarily due to reductions in headcount.

Professional service expenses were approximately $1,755,000 for the twelve months ended December 31, 2007 compared to approximately $1,530,000 the twelve months ended December 31, 2006. The increase of $225,000 or 15% is primarily due to increased legal expenses associated with the November 2007 financing partially offset by approximately $150,000 of decreased expenses associated with Underwriting expenses incurred in the twelve months ending December 31, 2006.

Interest Income

Interest income was approximately $138,000 for the twelve months ended December 31, 2007 compared to approximately $212,000 for the twelve months ended December 31, 2006. The decrease of approximately $74,000 reflects the impact of lower average balances of our short-term investments during the twelve months ended December 31, 2007.

Interest Expense

Interest expense totaled approximately $535,000 for the twelve months ended December 31, 2007 compared to approximately $188,000 for the twelve months ended December 31, 2006.

Interest expense for the twelve months ended December 31, 2007 consisted of:

Accrued interest expense of approximately $498,000 in connection with the New Notes;
Approximately $37,000 associated with the present value impact of $400,000 of payments made during such period under our settlement agreement with the Receiver for Lancer Offshore, Inc.;

Interest expense for the twelve months ended December 31, 2006 consisted of:

Approximately $183,000 for the accrued interest liability associated with our 6% Secured Convertible Notes due 2012 (“the Notes”),
Approximately $5,000 for the interest portion of the present value of payments we made to the Receiver of the Lancer Offshore, Inc. pursuant to certain settlement arrangements.

Amortization of Beneficial Conversion Feature

Expense due to amortization of beneficial conversion feature for the twelve months ended December 31, 2007 consisted of Beneficial conversion features of approximately $13,429,000 associated with the Series A and Series B 10% Secured Convertible Notes due 2008 (the “New Notes”); For the twelve months ended December 31, 2006 there were no expenses to amortization of beneficial conversion. The beneficial conversion feature is the difference between the conversion price of the New Notes ($0.706 per share) and the market price of our common stock on the commitment date ($1.35 per share) multiplied by the number of shares to be received on conversion of the note. The beneficial conversion feature is amortized over the life of the note or expensed in total at the time the note is converted into stock. Since the New Notes were both issued and converted in full during fiscal 2007, we expensed the entire beneficial conversion feature associated with the New Notes during such period.

Amortization of Debt Discount

Amortization of debt discount totaled approximately $4,556,000 for the twelve months ended December 31, 2007 compared to approximately $7,000 for the twelve months ended December 31, 2006. Amortization of debt discount for the twelve months ended December 31, 2007 consisted of amortization of the debt discounts on the New Notes of approximately $4,548,000 and amortization of the debt discount on the 6% Secured Convertible Notes due 2012 (the “Old Notes”) of approximately $8,000. For the twelve months ended December 31, 2006, amortization of debt discount consisted of approximately $5,000 associated with the amortization of the debt discount on the Old Notes. The value assigned to the warrants attached to the Old Notes and Series A notes is recorded as a discount on the notes they are attached to. The Series B note issued in exchange for the Old Notes was recorded at a discount to record the New Note at fair market value. The debt discounts are amortized over the life of the notes or expensed in total at the time the note is converted into stock. Since the New Notes were both issued and converted in full during fiscal 2007, we expensed the entire debt discount associated with the New Notes during such period.

Amortization of Deferred Financing Costs

Amortization of deferred financing costs totaled approximately $992,000 for the twelve months ended December 31, 2007 compared to no costs for the twelve months ended December 31, 2006.

For additional information about the Old Notes and the New Notes, please see the section “Liquidity and Capital Resources” below.

Gain on Exchange of Debt

For the twelve months ended December 31, 2007, the gain on exchange of debt includes approximately $330,000 for the gain realized on debt extinguishment which includes a gain on exchange of the Old Notes of approximately $254,000 and a gain of approximately $76,000 on the cancellation of the warrants that could have been issued upon certain prepayments of the Old Notes by the Company. There was no gain or loss on exchange of debt in the twelve months ended December 31, 2006.

Other Income and Expenses

Other income of approximately $167,000 includes the impact of approximately $261,000 for refunds received from New York State for business credits as Nephros qualifies as a Qualified Emerging Technology Company (“QETC”) and other expenses of approximately $94,000 for the twelve months ended December 31, 2007. The other expenses is comprised of the impact of the nine month gain on change in valuation of the derivative liability of approximately $7,000 and approximately $87,000 in expenses associated with the collection of the QETC tax credit reported in other income. In the twelve months ended December 31, 2006 the other income of approximately $2,000 is due to the change in value of the derivative.

Off-Balance Sheet Arrangements

The Company did not engage in any off-balance sheet arrangements during the periods ended December 31, 2007.

Going Concern and Management’s Response

The financial statements included in this Annual Report on Form 10-KSB have been prepared assuming that we will continue as a going concern, however, there can be no assurance that we will be able to do so. Our recurring losses and difficulty in generating sufficient cash flow to meet our obligations and sustain our operations raise substantial doubt about our ability to continue as a going concern, and our consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

We have incurred significant losses in our operations in each quarter since inception. For the years ended December 31, 2007 and 2006, we have incurred a net loss of approximately $26.4 million and $8.0 million, respectively. In addition, we have not generated positive cash flow from operations for the twelve months ended December 31, 2007 and 2006. To become profitable, we must increase revenue substantially and achieve and maintain positive gross and operating margins. If we are not able to increase revenue and gross and operating margins sufficiently to achieve profitability, our results of operations and financial condition will be materially and adversely affected.

At December 31, 2007, we had approximately $3,449,000 in cash and cash equivalents and $4,700,000 in short-term investments. However there can be no assurance that our short-term investments will provide the liquidity we expect. (See “Certain Risks and Uncertainties”). These operating plans primarily include the continued development and support of our business in the European market, continuation and completion of the US clinical trial for the H 2 H, organizational changes necessary to begin the commercialization of our water filtration business and the completion of current year milestones which are included in the Office of Naval Research appropriation.

There can be no assurance that our future cash flow will be sufficient to meet our obligations and commitments. If we are unable to generate sufficient cash flow from operations in the future to service our commitments we will be required to adopt alternatives, such as seeking to raise debt or equity capital, curtailing our planned activities or ceasing our operations. There can be no assurance that any such actions could be effected on a timely basis or on satisfactory terms or at all, or that these actions would enable us to continue to satisfy our capital requirements.

We continue to investigate additional funding opportunities, talking to various potential investors who could provide financing. However, there can be no assurance that we will be able to obtain further financing, do so on reasonable terms, do so on terms that will satisfy the continued listing standards of the American Stock Exchange (the “AMEX”) or do so on terms that would not substantially dilute your equity interests in us. If we are unable to raise additional funds on a timely basis, or at all, we will not be able to continue our operations and we may be de-listed from the AMEX.

For additional information describing the risks concerning our liquidity, please see “Certain Risks and Uncertainties” below.

Our future liquidity sources and requirements will depend on many factors, including:

the market acceptance of our products, and our ability to effectively and efficiently produce and market our products;
the availability of additional financing, through the sale of equity securities or otherwise, on commercially reasonable terms or at all;
our ability to liquidate our short term investments when needed;
the timing and costs associated with obtaining the Conformité Européene, or CE, mark, which demonstrates compliance with the relevant European Union requirements and is a regulatory pre requisite for selling our ESRD therapy products in the European Union and certain other countries that recognize CE marking (for products other than our OLpur MDHDF filter series, for which the CE mark was obtained in July 2003), or United States regulatory approval;
the ability to maintain the listing of our common stock on the AMEX;
the continued progress in and the costs of clinical studies and other research and development programs;

the costs involved in filing and enforcing patent claims and the status of competitive products; and
the cost of litigation, including potential patent litigation and any other actual or threatened litigation.

We expect to put our current capital resources to the following uses:

for the marketing and sales of our products;
to complete certain clinical studies, obtain appropriate regulatory approvals and expand our research and development with respect to our ESRD therapy products;
to continue our ESRD therapy product engineering;
to pursue business opportunities with respect to our DSU water-filtration product; and
for working capital purposes.

In response to recent illiquidity experienced with our auction rate securities, and in order to facilitate greater liquidity in our short-term investments, on March 27, 2008, our board of directors adopted an Investment, Risk Management and Accounting Policy. Such policy limits the types of instruments or securities in which we may invest our excess funds in the future to: U.S. Treasury Securities; Certificates of Deposit issued by money center banks; Money Funds by money center banks; Repurchase Agreements; and Eurodollar Certificates of Deposit issued by money center banks. This policy provides that our primary objectives for investments shall be the preservation of principal and achieving sufficient liquidity to meet our forecasted cash requirements. In addition, provided that such primary objectives are met, we may seek to achieve the maximum yield available under such constraints.

Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially. In the event that our plans change, our assumptions change or prove inaccurate, or if our existing cash resources, together with other funding resources including increased sales of our products, otherwise prove to be insufficient to fund our operations and we are unable to obtain additional financing, we will be required to adopt alternatives, such as curtailing our planned activities or ceasing our operations.

In June 2006, we entered into subscription agreements with certain investors who purchased an aggregate of $5,200,000 principal amount of our 6% Secured Convertible Notes due 2012 (the “Old Notes”). The Old Notes were secured by substantially all of our assets. However, as of September 19, 2007, the Old Notes were exchanged for New Notes as further described in the paragraphs below.

We entered into a Subscription Agreement (“Subscription Agreement”) with Lambda Investors LLC (“Lambda”) on September 19, 2007 (the “First Closing Date”), GPC 76, LLC on September 20, 2007, Lewis P. Schneider on September 21, 2007 and Enso Global Equities Partnership LP (“Enso”) on September 25, 2007 (collectively, the “New Investors”) pursuant to which the New Investors purchased an aggregate of approximately $12.7 million principal amount of our Series A 10% Secured Convertible Notes due 2008 (the “Purchased Notes”), for the face value thereof (the “Offering”). Concurrently with the Offering, we entered into an Exchange Agreement (the “Exchange Agreement”) with each of Southpaw Credit Opportunities Master Fund LP, 3V Capital Master Fund Ltd., Distressed/High Yield Trading Opportunities, Ltd., Kudu Partners, L.P. and LJHS Company (collectively, the “Exchange Investors” and together with the New Investors, the “Investors”), pursuant to which the Exchange Investors agreed to exchange the principal and accrued but unpaid interest in an aggregate amount of approximately $5.6 million under our Old Notes, for our new Series B 10% Secured Convertible Notes due 2008 in an aggregate principal amount of $5.3 million (the “Exchange Notes”, and together with the Purchased Notes, the “New Notes”) (the “Exchange”, and together with the Offering, the “Financing”).

We obtained the approval of our stockholders representing a majority of our outstanding shares to the issuance of shares of our common stock upon conversion of our New Notes and exercise of our Class D Warrants (as defined below) issuable upon such conversion, as further described below. The stockholder approval became effective on November 13, 2007, and the New Notes converted into shares of our common stock on November 14, 2007.

TABLE OF CONTENTS

All principal and accrued but unpaid interest (the “Conversion Amount”) under our New Notes automatically converted into (i) shares of our common stock at a conversion price per share of our common stock (the “Conversion Shares”) equal to $0.706 and (ii) in the case of our Purchased Notes, but not our Exchange Notes, Class D Warrants (the “Class D Warrants”) for purchase of shares of our common stock (the “Warrant Shares”) in an amount equal to 50% of the number of shares of our common stock issued to the New Investors in accordance with clause (i) above with an exercise price per share of our common stock equal to $0.90 (subject to anti-dilution adjustments). The Class D Warrants have a term of five years and are non-callable by us.

National Securities Corporation (“NSC”) and Dinosaur Securities, LLC (“Dinosaur” and together with NSC, the “Placement Agent”) acted as co-placement agents in connection with the Financing pursuant to an Engagement Letter, dated June 6, 2007 and a Placement Agent Agreement dated September 18, 2007. The Placement Agent received (i) an aggregate cash fee equal to 8% of the face amount of the Lambda Purchased Note and the Enso Purchased Note allocated and paid 6.25% to NSC and 1.75% to Dinosaur, and (ii) warrants (“Placement Agent Warrant”) with a term of five years from the date of issuance to purchase 10% of the aggregate number of shares of our common stock issued upon conversion of the Lambda Purchased Note and the Enso Purchased Note with an exercise price per share of our common stock equal to $0.90.

In connection with the sale of the New Notes, we entered into a Registration Rights Agreement with the Investors, dated as of the First Closing Date (the “Registration Rights Agreement”), pursuant to which we agreed to file an initial resale registration statement (“Initial Resale Registration Statement”) with the SEC no later than 60 days after we file a definitive version of our Information Statement on Schedule 14C with the SEC, and we filed such Initial Resale Registration Statement on December 20, 2007. We also agreed to use our commercially reasonable best efforts to have the Initial Resale Registration Statement declared effective within 240 days after filing of a definitive version of our Information Statement on Schedule 14C. In the event the Initial Resale Registration Statement has not been declared effective within such time period, for each 30-day period thereafter or portion thereof, we will pay each Investor as liquidated damages an amount equal to 1% of such Investor’s Conversion Amount in respect of the first ten 30-day periods, and 2% of such Investor’s Conversion Amount thereafter. If we fail timely to pay the liquidated damages, we will pay interest thereon at a rate of 15% per annum.

At December 31, 2007, we had an accumulated deficit of approximately $81,612,000, and we expect to incur additional losses in the foreseeable future at least until such time, if ever, that we are able to increase product sales or licensing revenue. We have financed our operations since inception primarily through the private placements of equity and debt securities and our initial public offering in September 2004, from licensing revenue received from Asahi Kasei Medical Co., Ltd. (“Asahi”), in March 2005, a private placement of convertible debenture in June 2006 and PIPE in September 2007.

Net cash used in operating activities was approximately $7,434,000 for the twelve months ended December 31, 2007 compared to approximately $7,300,000 for the twelve months ended December 31, 2006.

During 2007, the net cash used in operating activities was approximately $134,000 higher then the net cash used in operating activities during 2006. The most significant items contributing to this increase are highlighted below:

During 2007, our other liabilities decreased by approximately $564,000. This compares to a decrease of approximately $346,000 in 2006.
During 2007, our accounts receivable increased by approximately $154,000. This compares to a decrease in accounts receivable from 2005 to 2006.
During 2007, our inventory decreased by approximately $217,000. This compares to a decrease in inventory from 2005 to 2006 of approximately $362,000.

These factors were partially offset by the following:

During 2007, interest on convertible notes was approximately $498,000. This compares to interest on convertible notes of approximately $183,000 during 2006.

TABLE OF CONTENTS

During 2007, severance costs decreased by approximately $38,000. During 2006, severance costs decrease by approximately $249,000.

Net cash consumed by investing activities was approximately $2,045,000 for the twelve months ended December 31, 2007 compared to net cash provided by investing activities of approximately $1,590,000 for the twelve months ended December 31, 2006.

In 2007, approximately $145,000 of fixed assets was purchased primarily related to a mold ($143,000) and computer equipment ($2,000). Net cash consumed by investing activities was approximately $1,900,000 in net purchases of short term securities during the twelve months ended December 31, 2007. In 2006, our cash provided by investing activities was increased by $1,700,000 in net repayments of short term securities, which was partially offset by our purchase of approximately $110,000 of fixed assets primarily related to manufacturing and computer equipment.

Net cash provided by financing activities was approximately $12,677,000 for the twelve months ended December 31, 2007 compared to approximately $5,201,000 for the twelve months ended December 31, 2006. The net cash provided in the twelve months ended December 31, 2007 reflects the September 2007 private placement which raised approximately $12,677,000. The net cash provided in the twelve months ended December 31, 2006 reflects the sale of an aggregate of approximately $5,200,000 of our Notes and $1,441 from the exercise of options to purchase of our common stock.

Risks Related to Our Company

We have a history of operating losses and a significant accumulated deficit, and we may not achieve or maintain profitability in the future.

We have not been profitable since our inception in 1997. As of December 31, 2007, we had an accumulated deficit of approximately $81,612,000 primarily as a result of our research and development expenses and selling, general and administrative expenses. We expect to continue to incur additional losses for the foreseeable future as a result of a high level of operating expenses, significant up-front expenditures including the

28


TABLE OF CONTENTS

cost of clinical trials, production and marketing activities and very limited revenue from the sale of our products. We began sales of our first product in March 2004, and we may never realize sufficient revenues from the sale of our products or be profitable. Each of the following factors, among others, may influence the timing and extent of our profitability, if any:

the completion and success of additional clinical trials and of our regulatory approval processes for each of our ESRD therapy products in our target territories;
the market acceptance of HDF therapy in the United States and of our technologies and products in each of our target markets;
our ability to effectively and efficiently manufacture, market and distribute our products;
our ability to sell our products at competitive prices which exceed our per unit costs; and
the consolidation of dialysis clinics into larger clinical groups.

Our independent registered public accountants, in their audit report related to our financial statements for the year ended December 31, 2007, expressed substantial doubt about our ability to continue as a going concern.

Our independent registered public accounting firm has included an explanatory paragraph in their report on our financial statements included in this Annual Report on Form 10-KSB expressing doubt as to our ability to continue as a going concern. The accompanying financial statements have been prepared assuming that we will continue as a going concern, however, there can be no assurance that we will be able to do so. Our recurring losses and difficulty in generating sufficient cash flow to meet our obligations and sustain our operations, raises substantial doubt about our ability to continue as a going concern, and our consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Based on our current cash flow projections, we will need to raise additional funds through either the licensing or sale of our technologies or the additional public or private offerings of our securities. However, there is no guarantee that we will be able to obtain further financing, or to do so on reasonable terms. If we are unable to raise additional funds on a timely basis, or at all, we would be materially adversely affected.

Our short-term investments may not provide us with the liquidity that we intended them to provide. If we are unable to liquidate our short-term investments in a timely manner and on reasonable terms, then we may run out of funds with which to operate our business.

As of December 31, 2007, we held $4.7 million in auction rate securities (“ARS”) which are classified as short-term investments on our balance sheet. ARS are long-term debt instruments with interest rates reset through periodic short-term auctions. If there are insufficient buyers when such a periodic auction is held, then the auction “fails” and the holders of the ARS are unable to liquidate their investment through such auction. Starting in February 2008, the auctions for our ARS have “failed.” Accordingly, and for so long as such auctions continue to “fail,” these ARS are no longer functionally short-term.

To the extent that the auctions for our ARS continue to “fail” and no other markets develop for our ARS, we may be unable to liquidate these assets in a timely manner, on reasonable terms or at all. If we are unable to liquidate our short-term investments in a timely manner and on reasonable terms, then we may run out of funds with which to operate our business. If the current lack of liquidity relating to our ARS investments continues, it may have a material adverse effect on our ability to fund our ongoing operations and growth initiatives.

We may not be able to meet the American Stock Exchange’s continued listing standards and as a result, we may be delisted from the American Stock Exchange.

During 2006, we received notices from AMEX that we were not in compliance with certain conditions of the continued listing standards of Section 1003 of the AMEX Company Guide. Specifically, AMEX noted our failure to comply with Section 1003(a)(i) of the AMEX Company Guide relating to shareholders’ equity of less than $2,000,000 and losses from continuing operations and/or net losses in two out of our three most recent fiscal years; Section 1003(a)(ii) of the AMEX Company Guide relating to shareholders’ equity of less

29


TABLE OF CONTENTS

than $4,000,000 and losses from continuing operations and/or net losses in three out of our four most recent fiscal years; and Section 1003(a)(iii) of the AMEX Company Guide relating to shareholders’ equity of less than $6,000,000 and losses from continuing operations and/or net losses in our five most recent fiscal years. We submitted a plan in August 2006 to advise AMEX of the steps we had taken, and proposed to take, to regain compliance with the applicable listing standards.

On November 14, 2006, we received notice that the AMEX staff had reviewed our plan of compliance to meet the AMEX’s continued listing standards and that AMEX would continue our listing while we sought to regain compliance with the continued listing standards during the period ending January 17, 2008. During the plan period, we were required to provide the AMEX staff with updates regarding initiatives set forth in our plan of compliance. On November 14, 2007, all of our Series A 10% Secured Convertible Notes Due 2008 and our Series B 10% Secured Convertible Notes due 2008 (collectively, the “ Notes ”), representing an aggregate principal amount of $18 million, were converted into shares of our common stock and warrants, resulting in an increase in our stockholders’ equity. As a result, and notwithstanding our loss during the fourth quarter of 2007, our stockholders’ equity, at December 31, 2007, was approximately $8,756,000 and in excess of the $6,000,000 required by the AMEX rules.

On March 5, 2008, we received a letter from the AMEX acknowledging that we had resolved the continued listing deficiencies referenced in the AMEX’s letters dated July 17, 2006 and November 14, 2006. However, if we are not able to generate revenues from operations or timely raise equity capital, we are likely to again fail to comply with the AMEX rules regarding minimum shareholders’ equity. Should this occur within 12 months of January 17, 2009, then, in accordance with Section 1009(h) of the AMEX Company Guide, the AMEX may evaluate the relationship between the two incidents and apply more truncated procedures for compliance or immediately initiate delisting proceedings. Furthermore, there can be no assurance that we will not run afoul of the AMEX’s other continued listing standards. If we fail to meet such standards, then our common stock may be delisted from the AMEX.

On September 27, 2007, we received a warning letter from the AMEX stating that the staff of the AMEX Listing Qualifications Department had determined that we were not in compliance with Section 121B(2)(c) of the AMEX Company Guide requiring that at least 50% of the directors of our board of directors are independent directors. This non-compliance was due to the fact that William J. Fox, Judy Slotkin, W. Townsend Ziebold and Howard Davis resigned from our board of directors on September 19, 2007, concurrently with the appointment of Paul Mieyal and Arthur Amron to our board of directors, in accordance with our September 2007 financing. Consequently, our board of directors consisted of five directors, two of whom were independent. The AMEX had given us until December 26, 2007 to regain compliance with the independence require- ments. On November 16, 2007, James S. Scibetta was appointed to serve as an independent director on our board of directors. On December 5, 2007 we received a letter from the AMEX acknowledging that we had resolved the continued listing deficiency identified in their September 27, 2007 letter.

If our common stock is delisted by the AMEX, trading of our common stock would thereafter likely be conducted on the OTC Bulletin Board. In such case, the market liquidity for our common stock would likely be negatively affected, which may make it more difficult for holders of our common stock to sell their securities in the open market and we could face difficulty raising capital necessary for our continued operation. Investors may find it more difficult to dispose of or obtain accurate quotations as to the market value of our securities. In addition, our common stock, if delisted by the AMEX, may constitute “penny stock” (as defined in Rule 3a51-1 promulgated under the Securities Exchange Act of 1934, as amended) if we fail to meet certain criteria set forth in such Rule. Various practice requirements are imposed on broker-dealers who sell “penny stocks” to persons other than established customers and accredited investors. For these types of transactions, the broker-dealer must make a special suitability determination for the purchaser and have received the purchaser’s written consent to the transactions prior to sale. Consequently, if our common stock were to become “penny stock,” then the Rule may deter broker-dealers from recommending or selling our common stock, which could further negatively affect the liquidity of our common stock.

TABLE OF CONTENTS

Pursuant to the terms of our recently completed financing, if we fail to have the Initial Resale Registration Statement that we filed with the SEC declared effective in a timely manner as provided in the Registration Rights Agreement, then we may be required to pay liquidated damages to Investors.

In connection with our sale in September 2007 (the “Financing”) of an aggregate of approximately $18 million aggregate principal amount of Series A and Series B 10% Secured Convertible Notes due 2008 (the “New Notes”), we entered into a Registration Rights Agreement with the investors in the Financing (the “Investors”) pursuant to which we agreed to file an Initial Resale Registration Statement with the SEC no later than 60 days after we file a definitive Schedule 14C information statement with the SEC. The definitive Schedule 14C was filed with the SEC on October 24, 2007, and the Initial Resale Registration Statement was filed on December 20, 2007.

We have agreed to use our commercially reasonable best efforts to have the Initial Resale Registration Statement declared effective within 240 days after filing of the definitive Schedule 14C. In the event the Initial Resale Registration Statement has not been declared effective within such time period, for each 30-day period thereafter or portion thereof, we will pay each Investor, as liquidated damages, an amount equal to 1% of the principal and interest amount of such Investor’s New Notes that were automatically converted into shares of our common stock (the “Conversion Amount”) in respect of the first ten 30-day periods, and 2% of such Investor’s Conversion Amount thereafter. If we fail to pay the liquidated damages when due, then we shall pay interest thereon at a rate of 15% per annum.

Certain customers individually account for a large portion of our product sales, and the loss of any of these customers could have a material adverse effect on our sales.

For the year ended December 31, 2007, one of our customers accounted for 91% of our product sales. Also, this customer represented 98% of our accounts receivable as of December 31, 2007. We believe that the loss of this customer would have a material adverse effect on our product sales, at least temporarily, while we seek to replace such customer and/or self-distribute in the territories currently served by such customer.

We cannot sell our ESRD therapy products, including certain modifications thereto, until we obtain the requisite regulatory approvals and clearances in the countries in which we intend to sell our products. We have not obtained FDA approval for any of our ESRD therapy products, except for our HD190 filter, and cannot sell any of our other ESRD therapy products in the United States unless and until we obtain such approval. If we fail to receive, or experience a significant delay in receiving, such approvals and clearances then we may not be able to get our products to market and enhance our revenues.

Our business strategy depends in part on our ability to get our products into the market as quickly as possible. We obtained the Conformité Européene, or CE, mark, which demonstrates compliance with the relevant European Union requirements and is a regulatory prerequisite for selling our products in the European Union and certain other countries that recognize CE marking (collectively, “European Community”), for our OLpur MDHDF filter series product in 2003 and received CE marking in November 2006 for our water filtration product, the Dual Stage Ultrafilter (“DSU”). We have not yet obtained the CE mark for any of our other products. Similarly, we cannot sell our ESRD therapy products in the United States until we receive FDA clearance. Although we received approval of our IDE in March 2007 to begin clinical trials in the United States, until we complete the requisite U.S. human clinical trials and submit pre-market notification to the FDA pursuant to Section 510(k) of the FDC Act or otherwise comply with FDA requirements for a 510(k) approval, we will not be eligible for FDA approval for any of our products, except for our HD190 filter.

In addition to the pre-market notification required pursuant to Section 510(k) of the FDC Act, the FDA could require us to obtain pre-market approval of our ESRD therapy products under Section 515 of the FDC Act, either because of legislative or regulatory changes or because the FDA does not agree with our determination that we are eligible to use the Section 510(k) pre-market notification process. The Section 515 pre-market approval process is a significantly more costly, lengthy and uncertain approval process and could materially delay our products coming to market. If we do obtain clearance for marketing of any of our devices under Section 510(k) of the FDC Act, then any changes we wish to make to such device that could significantly affect safety and effectiveness will require clearance of a notification pursuant to Section 510(k), and we may need to submit clinical and manufacturing comparability data to obtain such approval or clearance.

31


TABLE OF CONTENTS

We could not market any such modified device until we received FDA clearance or approval. We cannot guarantee that the FDA would timely, if at all, clear or approve any modified product for which Section 510(k) is applicable. Failure to obtain timely clearance or approval for changes to marketed products would impair our ability to sell such products and generate revenues in the United States.

The clearance and/or approval processes in the European Community and in the United States can be lengthy and uncertain and each requires substantial commitments of our financial resources and our management’s time and effort. We may not be able to obtain further CE marking or any FDA approval for any of our ESRD therapy products in a timely manner or at all. Even if we do obtain regulatory approval, approval may be only for limited uses with specific classes of patients, processes or other devices. Our failure to obtain, or delays in obtaining, the necessary regulatory clearance and/or approvals with respect to the European Community or the United States would prevent us from selling our affected products in these regions. If we cannot sell some of our products in these regions, or if we are delayed in selling while awaiting the necessary clearance and/or approvals, our ability to generate revenues from these products will be limited.

If we are successful in our initial marketing efforts in some or all of our Target European Market and the United States, then we plan to market our ESRD therapy products in several countries outside of our Target European Market and the United States, including Korea and China, Canada and Mexico. Requirements pertaining to the sale of medical devices vary widely from country to country. It may be very expensive and difficult for us to meet the requirements for the sale of our ESRD therapy products in many of these countries. As a result, we may not be able to obtain the required approvals in a timely manner, if at all. If we cannot sell our ESRD therapy products outside of our Target European Market and the United States, then the size of our potential market could be reduced, which would limit our potential sales and revenues.

We have entered into an agreement with Asahi granting Asahi exclusive rights to manufacture and distribute filter products based on our OLpur MD190 hemodiafilter in Japan for 10 years commencing when the first such product receives Japanese regulatory approval. If the requisite Japanese regulatory approvals are not timely obtained, our potential license revenues will be limited.

Clinical studies required for our ESRD therapy products are costly and time-consuming, and their outcome is uncertain.

Before obtaining regulatory approvals for the commercial sale of any of our ESRD therapy products in the United States and elsewhere, we must demonstrate through clinical studies that our products are safe and effective. We received conditional approval for our IDE application from the FDA to begin human clinical trials of our OLpur H 2 H hemodiafiltration module and OLpur MD220 hemodiafilter. We were granted this approval on the condition that, by March 5, 2007, we submit a response to two informational questions from the FDA. We have responded to these questions. We have obtained approval from Western IRB, Inc., which enables us to proceed with our clinical trial. We began our clinical trials in the United States in the fourth quarter of 2007.

For products other than those for which we have already received marketing approval, if we do not prove in clinical trials that our ESRD therapy products are safe and effective, we will not obtain marketing approvals from the FDA and other applicable regulatory authorities. In particular, one or more of our ESRD therapy products may not exhibit the expected medical benefits, may cause harmful side effects, may not be effective in treating dialysis patients or may have other unexpected characteristics that preclude regulatory approval for any or all indications of use or limit commercial use if approved. The length of time necessary to complete clinical trials varies significantly and is difficult to predict. Factors that can cause delay or termination of our clinical trials include:

slower than expected patient enrollment due to the nature of the protocol, the proximity of subjects to clinical sites, the eligibility criteria for the study, competition with clinical trials for similar devices or other factors;
lower than expected retention rates of subjects in a clinical trial;
inadequately trained or insufficient personnel at the study site to assist in overseeing and monitoring clinical trials;

32


TABLE OF CONTENTS

delays in approvals from a study site’s review board, or other required approvals;
longer treatment time required to demonstrate effectiveness;
lack of sufficient supplies of the ESRD therapy product;
adverse medical events or side effects in treated subjects;
lack of effectiveness of the ESRD therapy product being tested; and
regulatory changes.

Even if we obtain positive results from clinical studies for our products, we may not achieve the same success in future studies of such products. Data obtained from clinical studies are susceptible to varying interpretations that could delay, limit or prevent regulatory approval. In addition, we may encounter delays or rejections based upon changes in FDA policy for device approval during the period of product development and FDA regulatory review of each submitted new device application. We may encounter similar delays in foreign countries. Moreover, regulatory approval may entail limitations on the indicated uses of the device. Failure to obtain requisite governmental approvals or failure to obtain approvals of the scope requested will delay or preclude our licensees or marketing partners from marketing our products or limit the commercial use of such products and will have a material adverse effect on our business, financial condition and results of operations.

In addition, some or all of the clinical trials we undertake may not demonstrate sufficient safety and efficacy to obtain the requisite regulatory approvals, which could prevent or delay the creation of marketable products. Our product development costs will increase if we have delays in testing or approvals, if we need to perform more, larger or different clinical trials than planned or if our trials are not successful. Delays in our clinical trials may harm our financial results and the commercial prospects for our products. Additionally, we may be unable to complete our clinical trials if we are unable to obtain additional capital.

We may be required to design and conduct additional clinical trials.

We may be required to design and conduct additional clinical trials to further demonstrate the safety and efficacy of our ESRD therapy product, which may result in significant expense and delay. The FDA and foreign regulatory authorities may require new or additional clinical trials because of inconclusive results from current or earlier clinical trials, a possible failure to conduct clinical trials in complete adherence to FDA good clinical practice standards and similar standards of foreign regulatory authorities, the identification of new clinical trial endpoints, or the need for additional data regarding the safety or efficacy of our ESRD therapy products. It is possible that the FDA or foreign regulatory authorities may not ultimately approve our products for commercial sale in any jurisdiction, even if we believe future clinical results are positive.

We cannot assure you that our ESRD therapy products will be safe and we are required under applicable law to report any product-related deaths or serious injuries or product malfunctions that could result in deaths or serious injuries, and such reports could trigger recalls, class action lawsuits and other events that could cause us to incur expenses and may also limit our ability to generate revenues from such products.

We cannot assure you that our ESRD therapy products will be safe. Under the FDC Act, we are required to submit medical device reports, or MDRs, to the FDA to report device-related deaths, serious injuries and product malfunctions that could result in death or serious injury if they were to recur. Depending on their significance, MDRs could trigger events that could cause us to incur expenses and may also limit our ability to generate revenues from such products, such as the following:

information contained in the MDRs could trigger FDA regulatory actions such as inspections, recalls and patient/physician notifications;
because the reports are publicly available, MDRs could become the basis for private lawsuits, including class actions; and
if we fail to submit a required MDR to the FDA, the FDA could take enforcement action against us.

33


TABLE OF CONTENTS

If any of these events occur, then we could incur significant expenses and it could become more difficult for us to gain market acceptance of our ESRD therapy products and to generate revenues from sales. Other countries may impose analogous reporting requirements that could cause us to incur expenses and may also limit our ability to generate revenues from sales of our ESRD therapy products.

Product liability associated with the production, marketing and sale of our products, and/or the expense of defending against claims of product liability, could materially deplete our assets and generate negative publicity which could impair our reputation.

The production, marketing and sale of kidney dialysis and water-filtration products have inherent risks of liability in the event of product failure or claim of harm caused by product operation. Furthermore, even meritless claims of product liability may be costly to defend against. Although we have acquired product liability insurance in the amount of $5,000,000 for our dialysis filters outside of the United States and intend to acquire additional product liability insurance upon commercialization of any of our additional products or upon introduction of any products in the United States, we may not be able to maintain or obtain this insurance on acceptable terms or at all. Because we may not be able to obtain insurance that provides us with adequate protection against all potential product liability claims, a successful claim in excess of our insurance coverage could materially deplete our assets. Moreover, even if we are able to obtain adequate insurance, any claim against us could generate negative publicity, which could impair our reputation and adversely affect the demand for our products, our ability to generate sales and our profitability.

Some of the agreements that we may enter into with manufacturers of our products and components of our products may require us:

To obtain product liability insurance; or
To indemnify manufacturers against liabilities resulting from the sale of our products.

For example, our agreement with Medica s.r.l. requires that we obtain and maintain certain minimum product liability insurance coverage and that we indemnify Medica against certain liabilities arising out of our products that they manufacture, provided they do not arise out of Medica’s breach of the agreement, negligence or willful misconduct. If we are not able to obtain and maintain adequate product liability insurance, then we could be in breach of these agreements, which could materially adversely affect our ability to produce our products and generate revenues. Even if we are able to obtain and maintain product liability insurance, if a successful claim in excess of our insurance coverage is made, then we may have to indemnify some or all of our manufacturers for their losses, which could materially deplete our assets.

If we violate any provisions of the FDC Act or any other statutes or regulations, then we could be subject to enforcement actions by the FDA or other governmental agencies.

We face a significant compliance burden under the FDC Act and other applicable statutes and regulations which govern the testing, labeling, storage, record keeping, distribution, sale, marketing, advertising and promotion of our ESRD therapy products. If we violate the FDC Act or other regulatory requirements at any time during or after the product development and/or approval process, we could be subject to enforcement actions by the FDA or other agencies, including:

fines;
injunctions;
civil penalties;
recalls or seizures of our products;
total or partial suspension of the production of our products;
withdrawal of any existing approvals or pre-market clearances of our products;
refusal to approve or clear new applications or notices relating to our products;
recommendations by the FDA that we not be allowed to enter into government contracts; and
criminal prosecution.

34


TABLE OF CONTENTS

Any of the above could have a material adverse effect on our business, financial condition and results of operations.

Significant additional governmental regulation could subject us to unanticipated delays which would adversely affect our sales and revenues.

Our business strategy depends in part on our ability to get our products into the market as quickly as possible. Additional laws and regulations, or changes to existing laws and regulations that are applicable to our business may be enacted or promulgated, and the interpretation, application or enforcement of the existing laws and regulations may change. We cannot predict the nature of any future laws, regulations, interpretations, applications or enforcements or the specific effects any of these might have on our business. Any future laws, regulations, interpretations, applications or enforcements could delay or prevent regulatory approval or clearance of our products and our ability to market our products. Moreover, changes that result in our failure to comply with the requirements of applicable laws and regulations could result in the types of enforcement actions by the FDA and/or other agencies as described above, all of which could impair our ability to have manufactured and to sell the affected products.

Access to the appropriations from the U.S. Department of Defense regarding the development of a dual-stage water ultrafilter could be subject to unanticipated delays which could adversely affect our potential revenues.

Our business strategy with respect to our DSU products depends in part on the successful development of DSU products for use by the military. We have contracted with the U.S. Office of Naval Research to develop a personal potable water purification system for warfighters, and Federal appropriations from the U.S. Department of Defense in an aggregate amount of $3 million have been approved for this purpose. If there are unanticipated delays in receiving the appropriations from the U.S. Department of Defense, our operations and potential revenues may be adversely affected.

Protecting our intellectual property in our technology through patents may be costly and ineffective. If we are not able to adequately secure or enforce protection of our intellectual property, then we may not be able to compete effectively and we may not be profitable.

Our future success depends in part on our ability to protect the intellectual property for our technology through patents. We will only be able to protect our products and methods from unauthorized use by third parties to the extent that our products and methods are covered by valid and enforceable patents or are effectively maintained as trade secrets. Our 13 granted U.S. patents will expire at various times from 2018 to 2022, assuming they are properly maintained.

The protection provided by our patents, and patent applications if issued, may not be broad enough to prevent competitors from introducing similar products into the market. Our patents, if challenged or if we attempt to enforce them, may not necessarily be upheld by the courts of any jurisdiction. Numerous publications may have been disclosed by, and numerous patents may have been issued to, our competitors and others relating to methods and devices for dialysis of which we are not aware and additional patents relating to methods and devices for dialysis may be issued to our competitors and others in the future. If any of those publications or patents conflict with our patent rights, or cover our products, then any or all of our patent applications could be rejected and any or all of our granted patents could be invalidated, either of which could materially adversely affect our competitive position.

Litigation and other proceedings relating to patent matters, whether initiated by us or a third party, can be expensive and time-consuming, regardless of whether the outcome is favorable to us, and may require the diversion of substantial financial, managerial and other resources. An adverse outcome could subject us to significant liabilities to third parties or require us to cease any related development, product sales or commercialization activities. In addition, if patents that contain dominating or conflicting claims have been or are subsequently issued to others and the claims of these patents are ultimately determined to be valid, then we may be required to obtain licenses under patents of others in order to develop, manufacture, use, import and/or sell our products. We may not be able to obtain licenses under any of these patents on terms acceptable to us, if at all. If we do not obtain these licenses, we could encounter delays in, or be prevented entirely from

35


TABLE OF CONTENTS

using, importing, developing, manufacturing, offering or selling any products or practicing any methods, or delivering any services requiring such licenses.

If we file patent applications or obtain patents in foreign countries, we will be subject to laws and procedures that differ from those in the United States. Such differences could create additional uncertainty about the level and extent of our patent protection. Moreover, patent protection in foreign countries may be different from patent protection under U.S. laws and may not be as favorable to us. Many non-U.S. jurisdictions, for example, prohibit patent claims covering methods of medical treatment of humans, although this prohibition may not include devices used for such treatment.

If we are not able to secure and enforce protection of our trade secrets through enforcement of our confidentiality and non-competition agreements, then our competitors may gain access to our trade secrets, we may not be able to compete effectively and we may not be profitable. Such protection may be costly and ineffective.

We attempt to protect our trade secrets, including the processes, concepts, ideas and documentation associated with our technologies, through the use of confidentiality agreements and non-competition agreements with our current employees and with other parties to whom we have divulged such trade secrets. If these employees or other parties breach our confidentiality agreements and non-competition agreements or if these agreements are not sufficient to protect our technology or are found to be unenforceable, then our competitors could acquire and use information that we consider to be our trade secrets and we may not be able to compete effectively. Policing unauthorized use of our trade secrets is difficult and expensive, particularly because of the global nature of our operations. The laws of other countries may not adequately protect our trade secrets.

If our trademarks and trade names are not adequately protected, then we may not be able to build brand loyalty and our sales and revenues may suffer.

Our registered or unregistered trademarks or trade names may be challenged, cancelled, infringed, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build brand loyalty. Over the long term, if we are unable to establish a brand based on our trademarks and trade names, then we may not be able to compete effectively and our sales and revenues may suffer.

If we are not able to successfully scale-up production of our products, then our sales and revenues will suffer.

In order to commercialize our products, we need to be able to produce them in a cost-effective way on a large scale to meet commercial demand, while maintaining extremely high standards for quality and reliability. If we fail to successfully commercialize our products, then we will not be profitable.

We expect to rely on a limited number of independent manufacturers to produce our OLpur MDHDF filter series and our other products, including the DSU. Our manufacturers’ systems and procedures may not be adequate to support our operations and may not be able to achieve the rapid execution necessary to exploit the market for our products. Our manufacturers could experience manufacturing and control problems as they begin to scale-up our future manufacturing operations, and we may not be able to scale-up manufacturing in a timely manner or at a commercially reasonable cost to enable production in sufficient quantities. If we experience any of these problems with respect to our manufacturers’ initial or future scale-ups of manufacturing operations, then we may not be able to have our products manufactured and delivered in a timely manner. Our products are new and evolving, and our manufacturers may encounter unforeseen difficulties in manufacturing them in commercial quantities or at all.

We will not control the independent manufacturers of our products, which may affect our ability to deliver our products in a timely manner. If we are not able to ensure the timely delivery of our products, then potential customers may not order our products, and our sales and revenues would be adversely affected.

Independent manufacturers of medical devices will manufacture all of our products and components. We have contracted Medica s.r.l., a developer and manufacturer of medical products with corporate headquarters located in Italy, to assemble and produce our OLpur MD190, MD220 and possibly other filters, including our

36


TABLE OF CONTENTS

DSU, and have an agreement with Membrana GmbH, a manufacturer of medical and technical membranes for applications like dialysis with corporate headquarters located in Germany, to produce the fiber for the OLpur MDHDF filter series. As with any independent contractor, these manufacturers will not be employed or otherwise controlled by us and will be generally free to conduct their business at their own discretion. For us to compete successfully, among other things, our products must be manufactured on a timely basis in commercial quantities at costs acceptable to us. If one or more of our independent manufacturers fails to deliver our products in a timely manner, then we may not be able to find a substitute manufacturer. If we are not or if potential customers believe that we are not able to ensure timely delivery of our products, then potential customers may not order our products, and our sales and revenues would be adversely affected.

The loss or interruption of services of any of our manufacturers could slow or stop production of our products, which would limit our ability to generate sales and revenues.

Because we are likely to rely on no more than two contract manufacturers to manufacture each of our products and major components of our products, a stop or significant interruption in the supply of our products or major components by a single manufacturer, for any reason, could have a material adverse effect on us. We expect most of our contract manufacturers will enter into contracts with us to manufacture our products and major components and that these contracts will be terminable by the contractors or us at any time under certain circumstances. We have not made alternative arrangements for the manufacture of our products or major components and we cannot be sure that acceptable alternative arrangements could be made on a timely basis, or at all, if one or more of our manufacturers failed to manufacture our products or major components in accordance with the terms of our arrangements. If any such failure occurs and we are unable to obtain acceptable alternative arrangements for the manufacture of our products or major components of our products, then the production and sale of our products could slow down or stop and our cash flow would suffer.

If we are not able to maintain sufficient quality controls, then the approval or clearance of our ESRD therapy products by the European Union, the FDA or other relevant authorities could be delayed or denied and our sales and revenues will suffer.

Approval or clearance of our ESRD therapy products could be delayed by the European Union, the FDA and the relevant authorities of other countries if our manufacturing facilities do not comply with their respective manufacturing requirements. The European Union imposes requirements on quality control systems of manufacturers, which are inspected and certified on a periodic basis and may be subject to additional unannounced inspections. Failure by our manufacturers to comply with these requirements could prevent us from marketing our ESRD therapy products in the European Community. The FDA also imposes requirements through quality system requirements, or QSR, regulations, which include requirements for good manufacturing practices, or GMP. Failure by our manufacturers to comply with these requirements could prevent us from obtaining FDA approval of our ESRD therapy products and from marketing such products in the United States. Although the manufacturing facilities and processes that we use to manufacture our OLpur MDHDF filter series have been inspected and certified by a worldwide testing and certification agency (also referred to as a notified body) that performs conformity assessments to European Union requirements for medical devices, they have not been inspected by the FDA. Similarly, although some of the facilities and processes that we expect to use to manufacture our OLpur H 2 H and OLpur NS2000 have been inspected by the FDA, they have not been inspected by any notified body. A “notified body” is a group accredited and monitored by governmental agencies that inspects manufacturing facilities and quality control systems at regular intervals and is authorized to carry out unannounced inspections. We cannot be sure that any of the facilities or processes we use will comply or continue to comply with their respective requirements on a timely basis or at all, which could delay or prevent our obtaining the approvals we need to market our products in the European Community and the United States.

Even with approval to market our ESRD therapy products in the European Community, the United States and other countries, manufacturers of such products must continue to comply or ensure compliance with the relevant manufacturing requirements. Although we cannot control the manufacturers of our ESRD therapy products, we may need to expend time, resources and effort in product manufacturing and quality control to assist with their continued compliance with these requirements. If violations of applicable requirements are

37


TABLE OF CONTENTS

noted during periodic inspections of the manufacturing facilities of our manufacturers, then we may not be able to continue to market the ESRD therapy products manufactured in such facilities and our revenues may be materially adversely affected.

If our products are commercialized, we may face significant challenges in obtaining market acceptance of such products, which could adversely affect our potential sales and revenues.

Our products are new to the market, and we do not yet have an established market or customer base for our products. Acceptance of our ESRD therapy products in the marketplace by both potential users, including ESRD patients, and potential purchasers, including nephrologists, dialysis clinics and other health care providers, is uncertain, and our failure to achieve sufficient market acceptance will significantly limit our ability to generate revenue and be profitable. Market acceptance will require substantial marketing efforts and the expenditure of significant funds by us to inform dialysis patients and nephrologists, dialysis clinics and other health care providers of the benefits of using our ESRD therapy products. We may encounter significant clinical and market resistance to our products and our products may never achieve market acceptance. We may not be able to build key relationships with physicians, clinical groups and government agencies, pursue or increase sales opportunities in Europe or elsewhere, or be the first to introduce hemodiafiltration therapy in the United States. Product orders may be cancelled, patients or customers currently using our products may cease to do so and patients or customers expected to begin using our products may not. Factors that may affect our ability to achieve acceptance of our ESRD therapy products in the marketplace include whether:

such products will be safe for use;
such products will be effective;
such products will be cost-effective;
we will be able to demonstrate product safety, efficacy and cost-effectiveness;
there are unexpected side effects, complications or other safety issues associated with such products; and
government or third party reimbursement for the cost of such products is available at reasonable rates, if at all.

Acceptance of our water filtration products in the marketplace is also uncertain, and our failure to achieve sufficient market acceptance and sell such products at competitive prices will limit our ability to generate revenue and be profitable. Our water filtration products and technologies may not achieve expected reliability, performance and endurance standards. Our water filtration products and technology may not achieve market acceptance, including among hospitals, or may not be deemed suitable for other commercial, military, industrial or retail applications.

Many of the same factors that may affect our ability to achieve acceptance of our ESRD therapy products in the marketplace will also apply to our water filtration products, except for those related to side effects, clinical trials and third party reimbursement.

If we cannot develop adequate distribution, customer service and technical support networks, then we may not be able to market and distribute our products effectively and/or customers may decide not to order our products, and, in either case, our sales and revenues will suffer.

Our strategy requires us to distribute our products and provide a significant amount of customer service and maintenance and other technical service. To provide these services, we have begun, and will need to continue, to develop a network of distribution and a staff of employees and independent contractors in each of the areas in which we intend to operate. We cannot assure you we will be able to organize and manage this network on a cost-effective basis. If we cannot effectively organize and manage this network, then it may be difficult for us to distribute our products and to provide competitive service and support to our customers, in which case customers may be unable, or decide not, to order our products and our sales and revenues will suffer.

TABLE OF CONTENTS

We may face significant risks associated with international operations, which could have a material adverse effect on our business, financial condition and results of operations.

We expect to manufacture and to market our products in our Target European Market and elsewhere outside of the United States. We expect that our revenues from our Target European Market will initially account for a significant portion of our revenues. Our international operations are subject to a number of risks, including the following:

fluctuations in exchange rates of the United States dollar could adversely affect our results of operations;
we may face difficulties in enforcing and collecting accounts receivable under some countries’ legal systems;
local regulations may restrict our ability to sell our products, have our products manufactured or conduct other operations;
political instability could disrupt our operations;
some governments and customers may have longer payment cycles, with resulting adverse effects on our cash flow; and
some countries could impose additional taxes or restrict the import of our products.

Any one or more of these factors could increase our costs, reduce our revenues, or disrupt our operations, which could have a material adverse effect on our business, financial condition and results of operations.

If we are unable to keep our key management and scientific personnel, then we are likely to face signifi- cant delays at a critical time in our corporate development and our business is likely to be damaged.

Our success depends upon the skills, experience and efforts of our management and other key personnel, including our chief executive officer, certain members of our scientific and engineering staff and our marketing executives. As a relatively new company, much of our corporate, scientific and technical knowledge is concentrated in the hands of these few individuals. We do not maintain key-man life insurance on any of our management or other key personnel other than Norman Barta, on whom we obtained a $1 million key-man life insurance policy. The loss of the services of one or more of our present management or other key personnel could significantly delay the development and/or launch of our products as there could be a learning curve of several months or more for any replacement personnel. Furthermore, competition for the type of highly skilled individuals we require is intense and we may not be able to attract and retain new employees of the caliber needed to achieve our objectives. Failure to replace key personnel could have a material adverse effect on our business, financial condition and operations.

Our fourth amended and restated certificate of incorporation, as amended, limits liability of our directors and officers, which could discourage you or other stockholders from bringing suits against our directors or officers in circumstances where you think they might otherwise be warranted.

Our fourth amended and restated certificate of incorporation, as amended, provides, with specific exceptions required by Delaware law, that our directors are not personally liable to us or our stockholders for monetary damages for any action or failure to take any action. In addition, we have agreed to, and our fourth amended and restated certificate of incorporation, as amended, and our second amended and restated bylaws provide for, mandatory indemnification of directors and officers to the fullest extent permitted by Delaware law. These provisions may discourage stockholders from bringing suit against a director or officer for breach of duty and may reduce the likelihood of derivative litigation brought by stockholders on our behalf against any of our directors or officers.

39


TABLE OF CONTENTS

If and to the extent we are found liable in certain proceedings or our expenses related to those or other legal proceedings become significant, then our liquidity could be materially adversely affected and the value of our stockholders’ interests in us could be impaired.

In April 2002, we entered into a letter agreement with Hermitage Capital Corporation (“Hermitage”), as placement agent, the stated term of which was from April 30, 2002 through September 30, 2004. As of February 2003, we entered into a settlement agreement with Hermitage pursuant to which, among other things: the letter agreement was terminated; the parties gave mutual releases relating to the letter agreement; and we agreed to issue Hermitage or its designees, upon the closing of certain transactions contemplated by a separate settlement agreement between us and Lancer Offshore, Inc., warrants exercisable until February 2006 to purchase an aggregate of 60,000 shares of common stock for $2.50 per share (or 17,046 shares of our common stock for $8.80 per share, if adjusted for the reverse stock split pursuant to the antidilution provisions of such warrant, as amended). Because Lancer Offshore, Inc. never satisfied the closing conditions and, consequently, a closing has not been held, we have not issued any warrants to Hermitage in connection with our settlement with them. In June 2004, Hermitage threatened to sue us for warrants it claims are due to it under its settlement agreement with us as well as a placement fee and additional warrants it claims are, or will be, owed in connection with our initial public offering completed on September 24, 2004, as compensation for allegedly introducing us to one of the underwriters. We had some discussions with Hermitage in the hopes of reaching an amicable resolution of any potential claims, most recently in January 2005. We have not heard from Hermitage since then.

If and to the extent we are found to have significant liability to Hermitage in any lawsuit Hermitage may bring against us, then our liquidity could be materially adversely affected and/or our stockholders could experience dilution in their investment in us and the value of our stockholders’ interests in us could be impaired.

We may use our financial resources in ways with which you do not agree and in ways that may not yield a favorable return.

Our management has broad discretion over the use of our financial resources, including the net proceeds from our initial public offering and our subsequent financings. Stockholders may not deem such uses desirable. Our use of our financial resources may vary substantially from our currently planned uses. We cannot assure you that we will apply such proceeds effectively or that we will invest such proceeds in a manner that will yield a favorable return or any return at all.

Several provisions of the Delaware General Corporation Law, our fourth amended and restated certificate of incorporation, as amended, and our second amended and restated bylaws could discourage, delay or prevent a merger or acquisition, which could adversely affect the market price of our common stock.

Several provisions of the Delaware General Corporation Law, our fourth amended and restated certificate of incorporation, as amended, and our second amended and restated bylaws could discourage, delay or prevent a merger or acquisition that stockholders may consider favorable, and the market price of our common stock could be reduced as a result. These provisions include:

authorizing our board of directors to issue “blank check” preferred stock without stockholder approval;
providing for a classified board of directors with staggered, three-year terms;
prohibiting us from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder unless certain provisions are met;
prohibiting cumulative voting in the election of directors;
limiting the persons who may call special meetings of stockholders; and
establishing advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted on by stockholders at stockholder meetings.

TABLE OF CONTENTS

As a relatively new company with little or no name recognition and with several risks and uncertainties that could impair our business operations, we are not likely to generate widespread interest in our common stock. Without widespread interest in our common stock, our common stock price may be highly volatile and an investment in our common stock could decline in value.

Unlike many companies with publicly traded securities, we have little or no name recognition in the investment community. We are a relatively new company and very few investors are familiar with either our company or our products. We do not have an active trading market in our common stock, and one might never develop, or if it does develop, might not continue.

Additionally, the market price of our common stock may fluctuate significantly in response to many factors, many of which are beyond our control. Risks and uncertainties, including those described elsewhere in this “Certain Risks and Uncertainties” section could impair our business operations or otherwise cause our operating results or prospects to be below expectations of investors and market analysts, which could adversely affect the market price of our common stock. As a result, investors in our common stock may not be able to resell their shares at or above their purchase price and could lose all of their investment.

Securities class action litigation is often brought against public companies following periods of volatility in the market price of such company’s securities. As a result, we may become subject to this type of litigation in the future. Litigation of this type could be extremely expensive and divert management’s attention and resources from running our company.

If we fail to maintain an effective system of internal controls over financial reporting, we may not be able to accurately report our financial results, which could have a material adverse effect on our business, financial condition and the market value of our securities.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports. If we cannot provide reliable financial reports, our reputation and operating results may be harmed. Management identified a material weakness in internal control over financial reporting, due to an insufficient number of resources in the accounting and finance department, resulting in (i) an ineffective review, monitoring and analysis of schedules, reconciliations and financial statement disclosures and (ii) the misapplication of generally accepted accounting principles (“U.S. GAAP”) and SEC reporting requirements. Due to the pervasive effect of the lack of resources, including a lack of resources that are appropriately qualified in the areas of U.S. GAAP and SEC reporting, and the potential impact on the financial statements and disclosures and the importance of the annual and interim financial closing and reporting process, in the aggregate, there is more than a remote likelihood that a material misstatement of the annual financial statements would not have been prevented or detected.

Management is in the process of remediating the above-mentioned weakness in our internal control over financial reporting and has designed the following steps to be implemented:

Develop procedures to implement a formal monthly closing calendar and process and hold monthly meetings to address the monthly closing process;
Establish a detailed timeline for review and completion of financial reports to be included in our Forms 10-QSB and 10-KSB;
Enhance the level of service provided by outside accounting service providers to further support and supplement our internal staff in accounting and related areas;
Seek additional staffing to provide additional resources for internal preparation and review of financial reports; and
Employ the use of appropriate supplemental SEC and U.S. GAAP checklists in connection with our closing process and the preparation of our Forms 10-QSB and 10-KSB.

The implementation of these remediation plans has been initiated and will continue during fiscal 2008. The material weakness will not be considered remediated until the applicable remedial procedures are tested and management has concluded that the procedures are operating effectively.

41


TABLE OF CONTENTS

The use of our financial resources will be required not only for implementation of these measures, but also for testing their effectiveness. Based on our existing funds, there can be no assurance that such procedures will be implemented on a timely basis, or at all. If we are not able to implement controls to avoid the occurrence of these kinds of problems in the future, we might report results that are not consistent with our actual results and we may need to restate results that will have been previously reported.

Our directors, executive officers and principal stockholders control a significant portion of our stock and, if they choose to vote together, could have sufficient voting power to control the vote on substantially all corporate matters.

As of December 31, 2007, our directors, executive officers and principal stockholders beneficially owned approximately 82.7% of our outstanding common stock. As of December 31, 2007, Lambda Investors LLC beneficially owned 37.7% of our outstanding common stock. As of December 31, 2007, Ronald O. Perelman beneficially owned 9.3% of our outstanding common stock. As of December 31, 2007, Enso Global Equities Master Partnership LP beneficially owned 9.0% of our outstanding common stock. As of December 31, 2007, Southpaw Credit Opportunity Master Fund LP beneficially owned 7.7% of our outstanding common stock. As of December 31, 2007, each of 3V Capital Master Fund Ltd. and Distressed/High Yield Trading Opportunities Ltd. beneficially owned 5.8% of our outstanding common stock. As of December 31, 2007, WPPN, LP, Wasserstein SBIC Ventures II L.P., WV II Employee Partners, LLC and BW Employee Holdings, LLC, entities that may be deemed to be controlled by Bruce Wasserstein, beneficially owned an aggregate of 5.1% of our outstanding common stock.

Our principal stockholders may have significant influence over our policies and affairs, including the election of directors. Should they act as a group, they will have the power to elect all of our directors and to control the vote on substantially all other corporate matters without the approval of other stockholders. Furthermore, such concentration of voting power could enable those stockholders to delay or prevent another party from taking control of our company even where such change of control transaction might be desirable to other stockholders.

Future sales of our common stock could cause the market price of our common stock to decline.

The market price of our common stock could decline due to sales of a large number of shares in the market, including sales of shares by our large stockholders, or the perception that such sales could occur. These sales could also make it more difficult or impossible for us to sell equity securities in the future at a time and price that we deem appropriate to raise funds through future offerings of common stock.

Prior to our initial public offering we entered into registration rights agreements with many of our existing security holders that entitled them to have an aggregate of 10,020,248 shares registered for sale in the public market. Moreover, many of those shares, as well as the 184,250 shares we sold to Asahi, could be sold in the public market without registration once they have been held for one year, subject to the limitations of Rule 144 under the Securities Act. In addition, we entered into a registration rights agreement with the holders of our New Notes pursuant to which we granted the holders certain registration rights with respect to the shares of common stock issuable upon conversion of the New Notes and upon exercise of the Class D Warrants.

Risks Related to the ESRD Therapy Industry

We expect to face significant competition from existing suppliers of renal replacement therapy devices, supplies and services. If we are not able to compete with them effectively, then we may not be profitable.

We expect to compete in the ESRD therapy market with existing suppliers of hemodialysis and peritoneal dialysis devices, supplies and services. Our competitors include Fresenius Medical Care AG and Gambro AB, currently two of the primary machine manufacturers in hemodialysis, as well as B. Braun Biotech International GmbH, and Nikkiso Corporation and other smaller machine manufacturers in hemodialysis. B. Braun, Fresenius, Gambro and Nikkiso also manufacture HDF machines. These companies and most of our other competitors have longer operating histories and substantially greater financial, marketing, technical, manufacturing and research and development resources and experience than we have. Our competitors could use these

42


TABLE OF CONTENTS

resources and experiences to develop products that are more effective or less costly than any or all of our products or that could render any or all of our products obsolete. Our competitors could also use their economic strength to influence the market to continue to buy their existing products.

We do not have a significant established customer base and may encounter a high degree of competition in further developing one. Our potential customers are a limited number of nephrologists, national, regional and local dialysis clinics and other healthcare providers. The number of our potential customers may be further limited to the extent any exclusive relationships exist or are entered into between our potential customers and our competitors. We cannot assure you that we will be successful in marketing our products to these potential customers. If we are not able to develop competitive products and take and hold sufficient market share from our competitors, we will not be profitable.

Some of our competitors own or could acquire dialysis clinics throughout the United States, our Target European Market and other regions of the world. We may not be able to successfully market our products to the dialysis clinics under their ownership. If our potential market is materially reduced in this manner, then our potential sales and revenues could be materially reduced.

Some of our competitors, including Fresenius and Gambro, manufacture their own products and own dialysis clinics in the United States, our Target European Market and/or other regions of the world. In 2005, Gambro divested its U.S. dialysis clinics to DaVita, Inc. and entered a preferred, but not exclusive, ten-year supplier arrangement with DaVita, whereby DaVita will purchase a significant amount of renal products and supplies from Gambro Renal Products. Because these competitors have historically tended to use their own products in their clinics, we may not be able to successfully market our products to the dialysis clinics under their ownership. According to the Fresenius 2007 Form 20-F annual report, Fresenius provides treatment in its own dialysis clinics to approximately 173,863 patients in approximately 2,238 facilities around the world of which approximately 1,602 facilities are located in the North America. According to DaVita’s press release dated February 13, 2008, DaVita provides treatment in 1,359 outpatient dialysis centers serving approximately 107,000 patients in the United States, and, according to DaVita’s 2006 Annual Report, DaVita and Fresenius combined treated approximately 65% of the United States outpatient dialysis patients in 2007.

Webelieve that there is currently a trend among ESRD therapy providers towards greater consolidation. If such consolidation takes the form of our competitors acquiring independent dialysis clinics, rather than such dialysis clinics banding together in independent chains, then more of our potential customers would also be our competitors. If our competitors continue to grow their networks of dialysis clinics, whether organically or through consolidation, and if we cannot successfully market our products to dialysis clinics owned by these competitors or any other competitors and do not acquire clinics ourselves, then our revenues could be adversely affected.

If the size of the potential market for our products is significantly reduced due to pharmacological or technological advances in preventative and alternative treatments for ESRD, then our potential sales and revenues will suffer.

Pharmacological or technological advances in preventative or alternative treatments for ESRD could significantly reduce the number of ESRD patients needing our products. These pharmacological or technological advances may include:

the development of new medications, or improvements to existing medications, which help to delay the onset or prevent the progression of ESRD in high-risk patients (such as those with diabetes and hypertension);
the development of new medications, or improvements in existing medications, which reduce the incidence of kidney transplant rejection; and
developments in the use of kidneys harvested from genetically-engineered animals as a source of transplants.

If these or any other pharmacological or technological advances reduce the number of patients needing treatment for ESRD, then the size of the market for our products may be reduced and our potential sales and revenues will suffer.

43


TABLE OF CONTENTS

If government and other third party reimbursement programs discontinue their coverage of ESRD treatment or reduce reimbursement rates for ESRD products, then we may not be able to sell as many units of our ESRD therapy products as otherwise expected, or we may need to reduce the anticipated prices of such products and, in either case, our potential revenues may be reduced.

Providers of renal replacement therapy are often reimbursed by government programs, such as Medicare or Medicaid in the United States, or other third-party reimbursement programs, such as private medical care plans and insurers. We believe that the amount of reimbursement for renal replacement therapy under these programs has a significant impact on the decisions of nephrologists, dialysis clinics and other health care providers regarding treatment methods and products. Accordingly, changes in the extent of coverage for renal replacement therapy or a reduction in the reimbursement rates under any or all of these programs may cause a decline in recommendations or purchases of our products, which would materially adversely affect the market for our products and reduce our potential sales. Alternatively, we might respond to reduced reimbursement rates by reducing the prices of our products, which could also reduce our potential revenues.

As the number of managed health care plans increases in the United States, amounts paid for our ESRD therapy products by non-governmental programs may decrease and we may not generate sufficient revenues to be profitable.

We expect to obtain a portion of our revenues from reimbursement provided by non-governmental programs in the United States. Although non-governmental programs generally pay higher reimbursement rates than governmental programs, of the non-governmental programs, managed care plans generally pay lower reimbursement rates than insurance plans. Reliance on managed care plans for dialysis treatment may increase if future changes to the Medicare program require non-governmental programs to assume a greater percentage of the total cost of care given to dialysis patients over the term of their illness, or if managed care plans otherwise significantly increase their enrollment of these patients. If the reliance on managed care plans for dialysis treatment increases, more patients join managed care plans or managed care plans reduce reimbursement rates, we may need to reduce anticipated prices of our ESRD therapy products or sell fewer units, and, in either case, our potential revenues would suffer.

If HDF does not become a preferred therapy for ESRD, then the market for our ESRD therapy products may be limited and we may not be profitable.

A significant portion of our success is dependent on the acceptance and implementation of HDF as a preferred therapy for ESRD. There are several treatment options currently available and others may be developed. HDF may not increase in acceptance as a preferred therapy for ESRD. If it does not, then the market for our ESRD therapy products may be limited and we may not be able to sell a sufficient quantity of our products to be profitable.

If the per-treatment costs for dialysis clinics using our ESRD therapy products are higher than the costs of clinics providing hemodialysis treatment, then we may not achieve market acceptance of our ESRD therapy products in the United States and our potential sales and revenues will suffer.

If the cost of our ESRD therapy products results in an increased cost to the dialysis clinic over hemodialysis therapies and such cost is not separately reimbursable by governmental programs or private medical care plans and insurers outside of the per-treatment fee, then we may not gain market acceptance for such products in the United States unless HDF therapy becomes the standard treatment method for ESRD. If we do not gain market acceptance for our ESRD therapy products in the United States, then the size of our market and our anticipated sales and revenues will be reduced.

Proposals to modify the health care system in the United States or other countries could affect the pricing of our products. If we cannot sell our products at the prices we plan to, then our margins and our profitability will be adversely affected.

A substantial portion of the cost of treatment for ESRD in the United States is currently reimbursed by the Medicare program at prescribed rates. Proposals to modify the current health care system in the United States to improve access to health care and control its costs are continually being considered by the

44


TABLE OF CONTENTS

federal and state governments. We anticipate that the U.S. Congress and state legislatures will continue to review and assess alternative health care reform proposals. We cannot predict whether these reform proposals will be adopted, when they may be adopted or what impact they may have on us if they are adopted. Any spending decreases or other significant changes in the Medicare program could affect the pricing of our ESRD therapy products. As we are not yet established in our business and it will take some time for us to begin to recoup our research and development costs, our profit margins are likely initially to be lower than those of our competitors and we may be more vulnerable to small decreases in price than many of our competitors.

Health administration authorities in countries other than the United States may not provide reimbursement for our products at rates sufficient for us to achieve profitability, or at all. Like the United States, these countries have considered health care reform proposals and could materially alter their government-sponsored health care programs by reducing reimbursement rates for dialysis products.

Any reduction in reimbursement rates under Medicare or foreign health care programs could negatively affect the pricing of our ESRD therapy products. If we are not able to charge a sufficient amount for our products, then our margins and our profitability will be adversely affected.

If patients in our Target European Market were to reuse dialyzers, then our potential product sales could be materially adversely affected.

In the United States, a majority of dialysis clinics reuse dialyzers — that is, a single dialyzer is disinfected and reused by the same patient. However, the trend in our Target European Market is towards not reusing dialyzers, and some countries (such as France, Germany, Italy and the Netherlands) actually forbid the reuse of dialyzers. As a result, each patient in our Target European Market can generally be expected to purchase more dialyzers than each United States patient. The laws forbidding reuse could be repealed and it may become generally accepted to reuse dialyzers in our Target European Market, just as it currently is in the United States. If reuse of dialyzers were to become more common among patients in our Target European Market, then there would be demand for fewer dialyzer units and our potential product sales could be materially adversely affected.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Nephros, Inc.

We have audited the accompanying consolidated balance sheet of Nephros, Inc. and Subsidiary (collectively, “the Company”) as of December 31, 2007, and the related consolidated statements of operations, stockholders’ equity and cash flows for the year then ended. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Nephros, Inc. and Subsidiary as of December 31, 2007, and the results of their operations and their cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company has incurred negative cash flow from operations and net losses since inception. These conditions, among others, raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

We have audited the accompanying consolidated balance sheet of Nephros, Inc. and subsidiary (the “Company”) as of December 31, 2006, and the related consolidated statement of operations, changes in stockholders’ equity, and cash flows for the year ended December 31, 2006. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements based on our audits.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2006, and the results of their operations and their cash flows for the year ended December 31, 2006, in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 2 to the consolidated financial statements, the Company adopted Statement of Financial Accounting Standards No. 123(R), Share-Based Payment , as of January 1, 2006, which changed its method of accounting for stock-based compensation.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company’s recurring losses and difficulty in generating sufficient cash flow to meet its obligations and sustain its operations raise substantial doubt about its ability to continue as a going concern.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — Organization and Nature of Operations

Nephros, Inc. (“Nephros” or the “Company”) was incorporated under the laws of the State of Delaware on April 3, 1997. Nephros was founded by health professionals, scientists and engineers affiliated with Columbia University to develop advanced End Stage Renal Disease (“ESRD”) therapy technology and products. The Company has three products in various stages of development in the hemodiafiltration, or HDF, modality to deliver improved therapy for ESRD patients. These are the OLpur TM MDHDF filter series or “dialyzers,” designed expressly for HDF therapy, the OLpur TM H 2 H TM , an add-on module designed to allow the most common types of hemodialysis machines to be used for HDF therapy, and the OLpur TM NS2000 system, a stand-alone hemodiafiltration machine and associated filter technology. In 2006, the Company introduced its Dual Stage Ultrafilter (“DSU”) water filter system, which represents a new and complementary product line to the Company’s existing ESRD therapy business. The DSU incorporates the Company’s unique and proprietary dual stage filter architecture.

On June 4, 2003, Nephros International Limited was incorporated under the laws of Ireland as a wholly-owned subsidiary of the Company. In August 2003, the Company established a European Customer Service and financial operations center in Dublin, Ireland.

Note 2 — Basis of Presentation and Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Nephros International Limited. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, at the date of the financial statements and the reported amounts of revenues and expenses, during the reporting period. Actual results could differ from those estimates.

Going Concern and Management’s Response

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. The Company’s recurring losses and difficulty in generating sufficient cash flow to meet its obligations and sustain its operations raise substantial doubt about its ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Based on the Company’s current cash flow projections, it will need to raise additional funds through either the licensing or sale of its technologies or the additional public or private offerings of its securities. The Company continues to investigate strategic funding opportunities as they are identified. However, there is no guarantee that the Company will be able to obtain further financing. If it is unable to raise additional funds on a timely basis or at all, the Company would not be able to continue its operations.

The Company has incurred significant losses in its operations in each quarter since inception. For the years ended December 31, 2007 and 2006, the Company has incurred a net loss of approximately $26.4 million and $8.0 million, respectively. In addition, the Company has not generated positive cash flow from operations for the twelve months ended December 31, 2007 and 2006. To become profitable, the Company must increase revenue substantially and achieve and maintain positive gross and operating margins. If the Company is not able to increase revenue and gross and operating margins sufficiently to achieve profitability, the Company’s results of operations and financial condition will be materially and adversely affected.

The Company’s current operating plans primarily include the continued development and support of the Company’s business in the European market, continuation and completion of the US clinical trial for the H 2 H,

organizational changes necessary to begin the commercialization of the Company’s water filtration business and the completion of current year milestones which are included in the Office of Naval Research appropriation.

The Company’s independent registered public accounting firm has included a paragraph in its audit report regarding the Company’s ability to continue as a going concern. Recent disturbances in the credit markets have impaired the liquidity of the Company’s short term investments which include auction rate securities. The Company believes that if the future liquidity of the Company’s short term investments could be assured, then the Company would have sufficient funds to meet its anticipated needs into the second quarter of 2009.

There can be no assurance that our future cash flow will be sufficient to meet our obligations and commitments. If we are unable to generate sufficient cash flow from operations in the future to service our commitments we will be required to adopt alternatives, such as seeking to raise debt or equity capital, curtailing our planned activities or ceasing our operations. There can be no assurance that any such actions could be effected on a timely basis or on satisfactory terms or at all, or that these actions would enable us to continue to satisfy our capital requirements.

The Company continues to investigate additional funding opportunities, talking to various potential investors who could provide financing. However, there can be no assurance that the Company will be able to obtain further financing, do so on reasonable terms, do so on terms that will satisfy the continued listing standards of the American Stock Exchange (the “AMEX”) or do so on terms that would not substantially dilute the equity interests in the Company. If the Company is unable to raise additional funds on a timely basis, or at all, the Company will not be able to continue its operations and the Company may be de-listed from the AMEX.

AMEX Delisting Issues

During 2006, the Company received notices from AMEX that it was not in compliance with certain conditions of the continued listing standards of Section 1003 of the AMEX Company Guide. Specifically, AMEX noted the Company’s failure to comply with Section 1003(a)(i) of the AMEX Company Guide relating to shareholders’ equity of less than $2,000,000 and losses from continuing operations and/or net losses in two out of the Company’s three most recent fiscal years; Section 1003(a)(ii) of the AMEX Company Guide relating to shareholders’ equity of less than $4,000,000 and losses from continuing operations and/or net losses in three out of the Company’s four most recent fiscal years; and Section 1003(a)(iii) of the AMEX Company Guide relating to shareholders’ equity of less than $6,000,000 and losses from continuing operations and/or net losses in the Company’s five most recent fiscal years. The Company submitted a plan in August 2006 to advise AMEX of the steps the Company had taken, and proposed to take, to regain compliance with the applicable listing standards.

On November 14, 2006, the Company received notice that the AMEX staff had reviewed the Company’s plan of compliance to meet the AMEX’s continued listing standards and that AMEX would continue the Company’s listing while the Company sought to regain compliance with the continued listing standards during the period ending January 17, 2008. During the plan period, the Company was required to provide the AMEX staff with updates regarding initiatives set forth in its plan of compliance. On November 14, 2007, all of the Company’s Series A 10% Secured Convertible Notes Due 2008 and Series B 10% Secured Convertible Notes due 2008 (collectively, the “ Notes ”), representing an aggregate principal amount of $18 million, were converted into shares of the Company’s common stock and warrants, resulting in an increase in the Company’s stockholders’ equity. As a result, and notwithstanding the Company’s loss during the fourth quarter of 2007, the Company’s stockholders’ equity, at December 31, 2007, was approximately $8,756,000 and in excess of the $6,000,000 required by the AMEX rules.

On March 5, 2008, the Company received a letter from the AMEX acknowledging that the Company had resolved the continued listing deficiencies referenced in the AMEX’s letters dated July 17, 2006 and

November 14, 2006. However, if the Company is not able to generate revenues from operations or timely raise equity capital, the Company is likely to again fail to comply with the AMEX rules regarding minimum shareholders’ equity. Should this occur within 12 months of January 17, 2009, then, in accordance with Section 1009(h) of the AMEX Company Guide, the AMEX may evaluate the relationship between the two incidents and apply more truncated procedures for compliance or immediately initiate delisting proceedings. Furthermore, there can be no assurance that the Company will not run afoul of the AMEX’s other continued listing standards. If the Company fails to meet such standards, then its common stock may be delisted from the AMEX.

On September 27, 2007, the Company received a warning letter from the AMEX stating that the staff of the AMEX Listing Qualifications Department had determined that the Company was not in compliance with Section 121B(2)(c) of the AMEX Company Guide requiring that at least 50% of the directors of the Company’s board of directors are independent directors. This non-compliance was due to the fact that William J. Fox, Judy Slotkin, W. Townsend Ziebold and Howard Davis resigned from the Company’s board of directors on September 19, 2007, concurrently with the appointment of Paul Mieyal and Arthur Amron to the board of directors, in accordance with the Company’s September 2007 financing. Consequently, the Company’s board of directors consisted of five directors, two of whom were independent. The AMEX had given the Company until December 26, 2007 to regain compliance with the independence requirements. On November 16, 2007, James S. Scibetta was appointed to serve as an independent director on the Company’s board of directors. On December 5, 2007 the Company received a letter from the AMEX acknowledging that the Company had resolved the continued listing deficiency identified in their September 27, 2007 letter.

Cash and Cash Equivalents

The Company invests its excess cash in bank deposits and money market accounts. The Company considers all highly liquid investments purchased with original maturities of three months or less from the date of purchase to be cash equivalents. Cash equivalents are carried at fair value, which approximate cost, and primarily consist of money market funds maintained at major U.S. financial institutions.

Short-Term Investments

All short-term investments, which are carried at fair market value, primarily represent auction rate debt securities (“ARS”). These securities have been classified as “available-for-sale.” Management determines the appropriate classification of its short-term investments at the time of purchase and evaluates such designation as of each balance sheet date. Interest earned on short-term investments is included in interest income. At December 31, 2007, the fair value of the available-for-sale securities was approximately $4,700,000. At December 31, 2006, the fair value of the available-for-sale securities was approximately $2,800,000. There were no realized or unrealized losses incurred on these securities for the years ended December 31, 2007 and 2006, respectively.

ARS are long-term debt instruments with interest rates reset through periodic short-term auctions. If there are insufficient buyers when such a periodic auction is held, then the auction “fails” and the holders of the ARS are unable to liquidate their investment through such auction. Starting in February 2008, the auctions for our ARS have “failed.” Accordingly, and for so long as such auctions continue to “fail,” these ARS are no longer functionally short-term.

Accounts Receivable

The Company provides credit terms to customers in connection with purchases of the Company’s products. Management periodically reviews customer account activity in order to assess the adequacy of the allowances provided for potential collection issues and returns. Factors considered include economic conditions, each customer’s payment and return history and credit worthiness. Adjustments, if any, are made to reserve balances following the completion of these reviews to reflect management’s best estimate of potential

losses. The allowance for doubtful accounts was approximately $7,000 at December 31, 2007 and approximately $10,000 at December 31, 2006. There was no allowance for sales returns at December 31, 2007 while there was approximately $38,000 at December 31, 2006.

Inventory

The Company engages third parties to manufacture and package inventory held for sale, takes title to certain inventory once manufactured, and warehouses such goods until packaged for final distribution and sale. Inventory consists of finished goods and raw materials (fiber) held at the manufacturers’ facilities, and are valued at the lower of cost or market using the first-in, first-out method.

Patents

The Company has filed numerous patent applications with the United States Patent and Trademark Office and in foreign countries. All costs and direct expenses incurred in connection with patent applications have been expensed as incurred.

Property and Equipment, net

Property and equipment, net is stated at cost and is being depreciated over the estimated useful lives of the assets, three to seven years, using the straight line method.

Impairment for Long-Lived Assets

The Company periodically evaluates whether current facts or circumstances indicate that the carrying value of its depreciable assets to be held and used may be recoverable. If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced by the long-lived assets, or the appropriate grouping of assets, is compared to the carrying value to determine whether an impairment exists. If an asset is determined to be impaired, the loss is measured based on the difference between the asset’s fair value and its carrying value. An estimate of the asset’s fair value is based on quoted market prices in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows. The Company reports an asset to be disposed of at the lower of its carrying value or its estimated net realizable market value. There was no impairment or loss incurred during the year.

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, short-term investments, accounts receivable, accounts payable and accrued expenses approximate fair value due to the short-term maturity of these instruments.

Revenue Recognition

Revenue is recognized in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104 “ Revenue Recognition” (“SAB No. 104”). SAB No. 104 requires that four basic criteria must be met before revenue can be recognized: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed and determinable; and (iv) collectibility is reasonably assured.

The Company recognizes revenue related to product sales when delivery is confirmed by its external logistics provider and the other criterion of SAB No. 104 were met. All costs and duties relating to delivery are absorbed by Nephros. All shipments are currently received directly by the Company’s customers. Sales made on a returned basis were recorded net of a provision for estimated returns. These estimates are revised as necessary, to reflect actual experience and market conditions. The returns provision is based on historical unit return levels and valued relative to debtors at the end of each quarter. For the year ended December 31, 2007, there were no returns and for the year ended December 31, 2006, returns were less than 5% of annual sales.

Shipping and Handling Costs

Shipping and handling costs are recorded as cost of goods sold and are approximately $35,000 and $48,000 for the years ended December 31, 2007 and 2006, respectively.

Research and Development Costs

Research and development costs are expensed as incurred.

Stock-Based Compensation

The Company has adopted Statement of Financial Accounting Standards (“SFAS”) No. 123 (Revised 2004) “ Share-Based Payment” (“SFAS 123R”), effective January 1, 2006. SFAS 123R requires the recognition of compensation expense in an amount equal to the fair value of all share-based payments granted to employees. The Company has elected the modified prospective transition method and therefore adjustments to prior periods are not required as a result of adopting SFAS 123R. Under this method, the provisions of SFAS 123R apply to all awards granted after the date of adoption and to any unrecognized expense of awards unvested at the date of adoption based on the grant date fair value. SFAS 123R also amends SFAS No. 95 “ Statement of Cash Flows ,” to require that excess tax benefits that had been reflected as operating cash flows be reflected as financing cash flows.

Income Taxes

The Company accounts for income taxes in accordance with SFAS No. 109 “ Accounting for Income Taxes ,” which requires accounting for deferred income taxes under the asset and liability method. Deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable in future years to differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities.

For financial reporting purposes, the Company has incurred a loss in each period since its inception. Based on available objective evidence, including the Company’s history of losses, management believes it is more likely than not that the net deferred tax assets will not be fully realizable. Accordingly, the Company provided for a full valuation allowance against its net deferred tax assets at December 31, 2007 and December 31, 2006.

In July 2006, the Financial Accounting Standards Board issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (FIN 48). FIN 48 creates a single accounting and disclosure model for uncertain tax positions, provides guidance on the minimum threshold that a tax uncertainty is required to meet before it can be recognized in the financial statements and applies to all tax positions taken by a company, both those deemed to be routine as well as those for which there may be a high degree of uncertainty.

FIN 48 establishes a two-step approach for evaluating tax positions. The first step, recognition, occurs when a company concludes (based solely on the technical aspects of the tax matter) that a tax position is more likely than not to be sustained on examination by a taxing authority. The second step, measurement, is only considered after step one has been satisfied and measures any tax benefit at the largest amount that is deemed more likely than not to be realized upon ultimate settlement of the uncertainty. Tax positions that fail to qualify for initial recognition are recognized in the first subsequent interim period that they meet the more likely than not standard, when they are resolved through negotiation or litigation with the taxing authority or upon the expiration of the statute of limitations. Derecognition of a tax position previously recognized would occur when a company subsequently concludes that a tax position no longer meets the more likely than not threshold of being sustained. FIN 48 also significantly expands the financial statement disclosure requirements relating to uncertain tax positions. FIN 48 is effective for fiscal years beginning after December 15, 2006. The adoption of the provisions of FIN 48 did not have a material impact on the Company’s financial position, results of operations and cash flows. During the year ended December 31, 2007, the Company recognized no adjustments for uncertain tax provisions.

Loss per Common Share

In accordance with SFAS No. 128 “ Earnings per Share ,” net loss per common share amounts (“basic EPS”) were computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding and excluding any potential dilution. Net loss per common share amounts assuming dilution (“diluted EPS”) is generally computed by reflecting potential dilution from conversion of convertible securities and the exercise of stock options and warrants. The following securities have been excluded from the dilutive per share computation as they are antidilutive.

   
  2007   2006
Stock options     2,256,580       2,314,547  
Warrants     11,090,248       391,768  

Foreign Currency Translation

Foreign currency translation is recognized in accordance with SFAS No. 52 “ Foreign Currency Translation .” The functional currency of Nephros International Limited is the Euro, and its translation gains and losses are included in accumulated other comprehensive income (loss). The balance sheet is translated at the year-end rate. The statement of operations is translated at the weighted average rate for the year.

Comprehensive Income (Loss)

The Company complies with the provisions of SFAS No. 130 “ Reporting Comprehensive Income ,” which requires companies to report all changes in equity during a period, except those resulting from investment by owners and distributions to owners, for the period in which they are recognized. Comprehensive income (loss) is the total of net income (loss) and all other non-owner changes in equity (or other comprehensive income (loss) ) such as unrealized gains or losses on securities classified as available-for-sale and foreign currency translation adjustments. For the years ended December 31, 2007 and 2006, the comprehensive loss was approximately $26,258,000 and $7,952,000, respectively.

Recent Accounting Pronouncements

In December 2007, the FASB issued SFAS No. 160 “ Noncontrolling Interests in Consolidated Financial Statements-an amendment of ARB No. 51 ” (“SFAS 160”), which requires the recognition of a noncontrolling interest (minority interest) as equity in the consolidated financial statements and separate from the parent’s equity; the inclusion of the amount of net income attributable to the noncontrolling interest in consolidated income on the face of the income statement; and a parent recognize a gain or loss in net income when a subsidiary is deconsolidated. SFAS 160 will be effective for the fiscal years beginning on or after December 15, 2008. The Company is currently evaluating the impact of adopting SFAS 160 on its financial position, cash flows, and results of operations.

In December 2007, the FASB issued SFAS No. 141 (Revised 2007) “ Business Combinations ” (“SFAS 141R”), which requires the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction; establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed; and requires the acquirer to disclose to investors, and other users, all of the information they need to evaluate and understand the nature and financial effect of the business combination. SFAS 141R will be effective for acquisitions with a date on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. The Company is currently evaluating the impact of adopting SFAS 141R on its financial position, cash flows, and results of operations.

In February 2007, the FASB issued SFAS No. 159 “ The Fair Value Option for Financial Assets and Financial Liabilities-Including an amendment of FASB Statement No. 115 ” (“SFAS 159”), which permits

entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. SFAS 159 will be effective for the fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact of adopting SFAS 159 on its financial position, cash flows, and results of operations.

In September 2006, the FASB issued SFAS No. 157 “ Fair Value Measurements ” (“SFAS 157”), which applies whenever other standards require (or permit) assets or liabilities to be measured at fair value. SFAS 157 established a fair value hierarchy that prioritizes the information used to develop the assumption that market participants would use when pricing an asset or liability. SFAS 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The Company is currently evaluating the impact of adopting SFAS 157 on the Company’s financial position, cash flows, and results of operations.

In December 2007, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 110 (“SAB 110”). SAB 110 was effective January 1, 2008 and expresses the views of the Staff of the SEC regarding the use of the simplified method, as discussed in SAB No. 107, in developing an estimate of the expected term of “plain vanilla” share options in accordance with SFAS No. 123R. We are currently evaluating the impact of applying the provisions of SAB 110 on our financial position and results of operations.

Note 3 — Short-Term Investments

At December 31, 2007, the fair value of the available-for-sale securities was approximately $4,700,000, all of which were auction rate securities (“ARS”). ARS are long-term debt instruments with interest rates reset through periodic short-term auctions. If there are insufficient buyers when such a periodic auction is held, then the auction “fails” and the holders of the ARS are unable to liquidate their investment through such auction. There were no realized or unrealized losses incurred on these securities for the years then ended December 31, 2007 and 2006, respectively.

Note 4 — Inventory

The Company’s inventory components as of December 31, 2007 and 2006, were approximately as follows:

   
  December 31,
     2007   2006
Raw Materials   $ 62,000     $ 54,000  
Finished Goods     304,000       484,000

Less: Inventory reserve     30,000       26,000  
Total Inventory   $ 336,000     $ 512,000  

During 2007, the design of the Dual Stage Ultra Filter product was changed. Accordingly, at December 31, 2007, this inventory has been written off as research and development and clinical trial expense in the amount of approximately $82,000.

The Company contracts with Medica s.r.l. to manufacture the Company’s ESRD therapy products. The Company owns certain manufacturing equipment located at Medica’s manufacturing plant in Italy. Depreciation expense for the years ended December 31, 2007 and 2006 was approximately $352,000 and $319,000.

Amortization expense relating to research and development assets is included in research and development and amounted to approximately $14,000 and $30,000 for the years ended December 31, 2007 and 2006.

Note 7 — Convertible Notes

Convertible Notes Due 2012

In June 2006, the Company entered into subscription agreements with certain investors who purchased an aggregate of $5,200,000 principal amount of 6% Secured Convertible Notes due 2012 (the “Old Notes”) issued by the Company for the face value thereof. The Company closed on the sale of the first tranche of Old Notes, in an aggregate principal amount of $5,000,000, on June 1, 2006 (the “First Tranche”) and closed on the sale of the second tranche of Old Notes, in an aggregate principal amount of $200,000, on June 30, 2006 (the “Second Tranche”). The Old Notes were secured by substantially all of the Company’s assets.

The Old Notes contain a prepayment feature that requires the Company to issue common stock purchase warrants to the holders for partial consideration of certain prepayments that the holders may demand under certain circumstances. Pursuant to the Old Notes, the Company must offer the holders the option (the “Holder Prepayment Option”) of prepayment (subject to applicable premiums) of their Old Notes, if the Company completes an asset sale in excess of $250,000 outside the ordinary course of business (a “Major Asset Sales”), to the extent of the net cash proceeds of such Major Asset Sale. Paragraph 12 of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities”, (SFAS 133”), provides that an embedded derivative shall be separated from the host contract and accounted for as a derivative instrument if and only if

Note 7 — Convertible Notes  – (continued)

certain criteria are met. In consideration of SFAS 133, the Company has determined that the Holder Prepayment Option is an embedded derivative to be bifurcated from the Old Notes and carried at fair value in the financial instruments. The Company recorded an embedded derivative liability of approximately $71,000 in the 3rd quarter of 2006. The change in value of the derivative liability was recorded as other income (expense). The change in value amounted to approximately ($7,000) through September 19, 2007, the Exchange Date, and $2,000 for the year ended December 31, 2006. Also, the debt discount, of approximately $71,000, created by bifurcating the Holder Prepayment Option, was being amortized over the term of the debt. The amortization of the debt discount through September 19, 2007, the Exchange Date, was recorded as interest expense and amounted to approximately $8,000 and was approximately $7,000 for the year ended December 31, 2006.

On September 19, 2007, the Old Notes were exchanged for New Notes as described under the heading “Convertible Notes due 2008.”

Convertible Notes Due 2008

The Company entered into a Subscription Agreement (“Subscription Agreement”) with Lambda Investors LLC (“Lambda”) on September 19, 2007 (the “First Closing Date”), GPC 76, LLC on September 20, 2007, Lewis P. Schneider on September 21, 2007 and Enso Global Equities Partnership LP (“Enso”) on September 25, 2007 (collectively, the “New Investors”) pursuant to which the New Investors purchased an aggregate of approximately $12.7 million principal amount of Series A 10% Secured Convertible Notes due 2008 (the “Purchased Notes”) of the Company, for the face value thereof (the “Offering”). Concurrently with the Offering, the Company entered into an Exchange Agreement (the “Exchange Agreement”) with each of Southpaw Credit Opportunities Master Fund LP, 3V Capital Master Fund Ltd., Distressed/High Yield Trading Opportunities, Ltd., Kudu Partners, L.P. and LJHS Company (collectively, the “Exchange Investors” and together with the New Investors, the “Investors”), pursuant to which the Exchange Investors agreed to exchange the principal and accrued but unpaid interest in an aggregate amount of approximately $5.6 million under the Old Notes, for new Series B 10% Secured Convertible Notes due 2008 in an aggregate principal amount of $5.3 million (the “Exchange Notes”, and together with the Purchased Notes, the “New Notes”) (the “Exchange”, and together with the Offering, the “Financing”).

The Company has obtained the approval of its stockholders representing a majority of its outstanding shares to the issuance of shares of its common stock issuable upon conversion of the New Notes and exercise of the Class D Warrants (as defined below) issuable upon such conversion, as further described below. The stockholder approval was effective on November 13, 2007. Accordingly, the New Notes were converted into common stock of the Company on November 14, 2007.

Upon effectiveness of such approval, all principal and accrued but unpaid interest (the “Conversion Amount”) under the New Notes automatically converted into (i) shares of the Company’s common stock at a conversion price per share of the Company’s common stock (the “Conversion Shares”) equal to $0.706 and (ii) in the case of the Purchased Notes, but not the Exchange Notes, Class D Warrants (the “Class D Warrants”) for purchase of shares of the Company’s common stock (the “Warrant Shares”) in an amount equal to 50% of the number of shares of the Company’s common stock issued to the New Investors in accordance with clause (i) above with an exercise price per share of the Company’s common stock equal to $0.90 (subject to anti-dilution adjustments).

National Securities Corporation (“NSC”) and Dinosaur Securities, LLC (“Dinosaur” and together with NSC, the “Placement Agent”) acted as co-placement agents in connection with the Financing pursuant to an Engagement Letter, dated June 6, 2007 and a Placement Agent Agreement dated September 18, 2007. The Placement Agent received (i) an aggregate cash fee equal to 8% of the face amount of the Lambda Purchased Note and the Enso Purchased Note allocated and paid 6.25% to NSC and 1.75% to Dinosaur, and (ii) warrants (“Placement Agent Warrant”) with a term of five years from the date of issuance to purchase 10% of the

aggregate number of shares of the Company’s common stock issued upon conversion of the Lambda Purchased Note and the Enso Purchased Note with an exercise price per share of the Company’s common stock equal to $0.90.

The Company recorded a debt discount related to the issuance of the Exchange Notes, of approximately $785,000 and was amortizing the discount over the term of the Exchange Notes. The amortization of the debt discount through November 14, 2007, the Automatic Conversion Date, was recorded as interest expense and amounted to approximately $120,000. The remaining balance of the debt discount of approximately $665,000 was written off to interest expense when the Exchange Notes were converted into common stock.

On October 24, 2007, the SEC accepted the Schedule 14C filed by the Company thereby setting the “Automatic Conversion Date” of both the Series A and Series B Notes to be November 14, 2007. The acceptance date also became the measurement date to calculate the value of the embedded beneficial conversion feature in each note and the detachable warrants included in the Series A Notes.

The Company allocated the proceeds from the sale of the Purchased Notes between the Purchased Notes and the Class D Warrants based upon their relative fair values, resulting in the recognition of a discount of approximately $3,763,000. The value of the Class D Warrants was computed using the Black-Scholes option pricing model. Second, in accordance with EITF No. 00-27, “Application of Issue 98 - 5 to Certain Convertible Instruments” after allocating a portion of the Purchased Notes proceeds to the Class D Warrants, the Company calculated the value of the embedded beneficial conversion feature in the Purchased Notes by comparing the carrying value of the proceeds, net of the warrant discount, to the fair value of the shares issuable upon conversion of the Purchased Notes. If there is a beneficial conversion, it is recognized, as an additional discount to the extent of the remaining proceeds. The Company recognized an additional discount of approxi- mately $8,914,000 for the embedded beneficial conversion feature. The amortization of the discount and beneficial conversion feature through November 14, 2007, the Automatic Conversion Date, was recorded as interest expense and amounted to approximately $239,000 and $566,000. The remaining balances of the discount of approximately $3,524,000 and beneficial conversion feature of approximately $8,348,000 were written off to interest expense when the Purchased Notes were converted into common stock. On November 14, 2007 the Purchased Notes, in aggregate principal amount of approximately $12,677,000, and related accrued interest of approximately $190,000, were converted into an aggregate of 18,225,128 shares of common stock.

In accordance with EITF No. 98-5, “Accounting for Convertible Securities with Beneficial Conversion Features or Contingently Adjustable Conversion Ratios,” the Company calculated the value of the embedded beneficial conversion feature in the Exchange Notes by comparing the carrying value of the proceeds to the fair value of the shares issuable upon conversion of the Exchange Notes. The Company recognized a discount of approximately $4,515,000 for the embedded beneficial conversion feature. The amortization of the beneficial conversion feature through November 14, 2007, the Automatic Conversion Date, was recorded as interest expense and amounted to approximately $286,000. The remaining balance of the beneficial conversion feature of approximately $4,229,000 was written off to interest expense when the Exchange Notes were converted into common stock. On November 14, 2007 the Exchange Notes, in aggregate principal amount of approximately $5,300,000, and related accrued interest of approximately $81,000, were converted into an aggregate of 7,622,259 shares of common stock.

As compensation for its services as co-placement agents, National Securities Corporation and Dinosaur Securities, LLC, received cash in the amount of approximately $775,000 and $217,000 and five-year warrants to purchase an aggregate of approximately 1,756,374 shares of the Company’s common stock at an exercise price of $0.90 per share. These warrants contain a “cashless exercise” option. The total fee of approximately $2,039,000, including the fair value of the warrants issued, was recorded as deferred financing costs. The deferred costs were written off and recorded as interest expense on November 14, 2007, the Automatic Conversion Date.

Acceleration of Non Cash Charges Upon Conversion of New Notes

The conversion of the New Notes to equity on November 14, 2007 resulted in an aggregate non cash charge of approximately $17,985,000, of which approximately $13,429,000 relates to the amortization of the beneficial conversion features and approximately $4,556,000 relates to the amortization of the debt discount.

Note 8 — Income Taxes

A reconciliation of the income tax provision computed at the statutory tax rate to the Company’s effective tax rate is as follows:

   
  2007   2006
U.S. federal statutory rate     35.00 %       35.00 %  
State & local taxes     11.26 %       8.67 %  
Tax on foreign operations     (0.51 )%       (5.68 )%  
Other     (1.21 )%       0.01 %  
Valuation Allowance     (45.53 )%       (38.00 )%  
Effective tax rate     (0.99 )%       0.00 %  

Significant components of the Company’s deferred tax assets as of December 31, 2007 and 2006 are approximately as follows:

   
  2007   2006
Deferred tax assets:
                 
Net operating loss carry forwards   $ 26,734,000     $ 14,927,000  
Research and development credits     896,000       825,000  
Nonqualified stock option compensation expense     1,703,000       1,367,000  
Other Temporary Book – Tax differences     2,000       12,000  
Total deferred tax assets     29,335,000       17,131,000  
Valuation allowance for deferred tax assets     (29,335,000 )       (17,131,000 )  
Net deferred tax assets   $     $  

A valuation allowance has been recognized to offset the Company’s net deferred tax asset as it is more likely than not that such net asset will not be realized. The Company primarily considered its historical loss and potential Internal Revenue Code Section 382 limitations to arrive at its conclusion that a valuation allowance was required.

At December 31, 2007, the Company had Federal, New York State and New York City income tax net operating loss carryforwards of approximately $55 million each and foreign income tax net operating loss carryforwards of approximately $9 million. The Company also had Federal research tax credit carryforwards of approximately $896,000 at December 31, 2007 and $825,000 at December 31, 2006. The Federal net operating loss and tax credit carryforwards will expire at various times between 2012 and 2026 unless utilized. During 2007 the Company received approximately $260,000 payroll based research and development credits from New York State.

On January 1, 2007, the Company adopted the provisions of FIN 48, “Accounting for Uncertainty in Income Taxes — An interpretation of FASB Statement No.109.” Implementation of FIN 48 did not result in a cumulative effect adjustment to the accumulated deficit.

It is the Company’s policy to report interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

Share-Based Payment

Prior to the Company’s initial public offering, options were granted to employees, non-employees and non-employee directors at exercise prices which were lower than the fair market value of the Company’s stock on the date of grant. After the date of the Company’s initial public offering, stock options are granted to employees, non-employees and non-employee directors at exercise prices equal to the fair market value of the Company’s stock on the date of grant. Stock options granted have a life of 10 years and vest upon a combination of the following: immediate vesting; straight line vesting of two, three, or four years; and upon the achievement of certain milestones.

Expense is recognized, net of expected forfeitures, over the vesting period of the options. For options that vest upon the achievement of certain milestones, expense is recognized when it is probable that the condition will be met. Stock based compensation expense recognized for the years ended December 31, 2007 and 2006 was approximately $885,000 or $0.06 per share and approximately $475,000 or $0.04 per share.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the below assumptions related to risk-free interest rates, expected dividend yield, expected lives and expected stock price volatility.

   
  Option Pricing Assumptions
Grant Year   2007   2006
Stock Price Volatility     84% – 86 %       65% to 92 %  
Risk-Free Interest Rates     3.97% to 4.83 %       4.34% to 4.97 %  
Expected Life (in years)     5.8 to 6.0       5.8 to 6.0

Note 9 — Warrants, Share-Based Payments and Stock Plans  – (continued)

There is no expected dividend yield. Expected volatility is based on historical volatility of the Company’s common stock at the time of grant. The risk-free interest rate is based on the U.S. Treasury yields in effect at the time of grant for periods corresponding with the expected life of the options. For the expected life, the Company is using the simplified method as described in the SEC Staff Accounting Bulletin 107. This method assumes that stock option grants will be exercised based on the average of the vesting periods and the grant’s life.

The total fair value of options vested during the fiscal year ended December 31, 2007 was approximately $1,473,000. The total fair value of options vested during the fiscal year ended December 31, 2006 was approximately $522,000.

Stock Plans

In 2000, the Company adopted the Nephros 2000 Equity Incentive Plan. In January 2003, the Board of Directors adopted an amendment and restatement of the plan and renamed it the Amended and Restated Nephros 2000 Equity Incentive Plan (the “2000 Plan”), under which 2,130,750 shares of common stock had been authorized for issuance upon exercise of options granted and which may have been granted by the Company. As of December 31, 2006, 1,316,235 options had been issued to employees and were outstanding. The options expire on various dates between January 24, 2010 and March 15, 2014 and vest upon a combination of the following: immediate vesting; straight line vesting of two, three or four years; and certain milestones.

The Board retired the 2000 Plan in June 2004, and thereafter no additional awards may be granted under the 2000 Plan.

In 2004, the Board of Directors adopted and the Company’s stockholders approved the Nephros, Inc. 2004 Stock Incentive Plan, and, in June 2005, the Company’s stockholders approved an amendment to such plan (as amended, the “2004 Plan”), that increased to 800,000 the number of shares of the Company’s common stock that are authorized for issuance by the Company pursuant to grants of awards under the 2004 Plan. Subsequently in May 2007, the Company’s stockholders approved an amendment to such plan (as amended, the “2004 Plan”), that increased to 1,300,000 the number of shares of the Company’s common stock that are authorized for issuance by the Company pursuant to grants of awards under the 2004 Plan.

As of December 31, 2007, 628,500 options had been issued to employees under the 2004 Plan and were outstanding.

Settlement Agreements

Plexus Services Corp.

In June 2002, the Company entered into a settlement agreement with one of its suppliers, Plexus Services Corp. The Company had an outstanding liability to such supplier in the amount of approximately $1,900,000. Pursuant to this settlement agreement, the Company and the supplier agreed to release each other from any and all claims or liabilities, whether known or unknown, that each had against the other as of the date of the settlement agreement, except for obligations arising out of the settlement agreement itself. The settlement agreement required the Company to grant to the supplier (i) warrants to purchase 170,460 shares of common stock of the Company at an exercise price of approximately $10.56 per share that expire in June 2007 and (ii) cash payments of an aggregate amount of $650,000 in three installments. The warrants were valued at $400,000 using the Black-Scholes model. Accordingly, the Company recorded a gain of approximately $850,000 based on such settlement agreement. On June 19, 2002, the Company issued the warrant to the supplier, and on August 7, 2002, the Company satisfied the first $300,000 installment of the agreement. The second installment of $100,000 was due on February 7, 2003, and the Company paid $75,000 towards the installment. On November 11, 2004, after the successful closing of its initial public offering, the Company paid an additional $25,000 and agreed with the supplier to pay the remaining $250,000 over time. The final payment of $25,000 was paid on September 26, 2007.

Lancer Offshore, Inc.

In August 2002, the Company entered into a subscription agreement with Lancer Offshore, Inc. (“Lancer”), pursuant to which Lancer agreed to purchase, in several installments, (1) $3,000,000 principal amount of secured convertible notes due March 15, 2003 and (2) warrants to purchase until December 2007 an aggregate of 68,184 shares of the Company’s common stock at an exercise price of approximately $8.80 per share. In accordance with the subscription agreement, the first installment of securities, consisting one-half of the total, were tendered. However, Lancer failed to fund the remaining installments. Following this failure, the Company entered into a settlement agreement with Lancer dated as of January 31, 2003, pursuant to which, among other things, the $1,500,000 secured convertible note issued to Lancer in August 2002 was cancelled. However, Lancer never fulfilled the conditions to the subsequent closing under the settlement agreement and, accordingly, the Company never issued the $1,500,000 non-convertible note that the settlement agreement provided would be issued at such closing.

The above transaction resulted in the Company becoming a defendant in an action brought by the Receiver for Lancer Offshore, Inc. (the “Ancillary Proceeding”) that was commenced on March 8, 2004. On December 19, 2005, the Court approved the Stipulation of Settlement with respect to the Ancillary Proceeding dated November 8, 2005 (the “Settlement”). Pursuant to the terms of the Settlement, the Company agreed to pay the Receiver an aggregate of $900,000 under the following payment terms: $100,000 paid on January 5, 2006; and four payments of $200,000 each at six month intervals thereafter. In addition, any warrants previously issued to Lancer were cancelled, and, on January 18, 2006, the Company issued to the Receiver warrants to purchase 21,308 shares of the Company’s common stock at $1.50 per share exercisable until January 18, 2009. The final payment of $400,000 was made on October 3, 2007.

Manufacturing and Suppliers

The Company does not intend to manufacture any of its products or components. The Company has entered into an agreement dated May 12, 2003, and amended on March 22, 2005 with Medica s.r.l., (“Medica”) a developer and manufacturer of medical products with corporate headquarters located in Italy, to assemble and produce the Company’s OLpur MD190, MD220 or other filter products at the Company’s option. The agreement requires the Company to purchase from Medica the OLpur MD190s and MD220s or other filter products that the Company directly markets in Europe, or are marketed by our distributor in Italy. In addition, Medica will be given first consideration in good faith for the manufacture of OLpur MD190s, MD220s or other filter products that the Company does not directly market. No less than semiannually, Medica will provide a report to representatives of both parties to the agreement detailing any technical know-how that Medica has developed that would permit them to manufacture the filter products less expensively and both parties will jointly determine the actions to be taken with respect to these findings. If the fiber wastage with respect to the filter products manufactured in any given year exceeds 5%, then Medica will reimburse the Company up to half of the cost of the quantity of fiber represented by excess wastage. Medica will manufacture the OLpur MD190 or other filter products in accordance with the quality standards outlined in the agreement. Upon recall of any OLpur MD190 or other filter product due to Medica’s having manufactured one or more products that fail to conform to the required specifications or having failed to manufacture one or more products in accordance with any applicable laws, Medica will be responsible for the cost of recall. The agreement also requires that the Company maintain certain minimum product-liability insurance coverage and that the Company indemnify Medica against certain liabilities arising out of the Company’s products that they manufacture, providing they do not arise out of Medica’s breach of the agreement, negligence or willful misconduct. The term of the agreement is through May 12, 2009, with successive automatic one-year renewal terms, until either party gives the other notice that it does not wish to renew at least 90 days prior to the end of the term. The agreement may be terminated prior to the end of the term by either party upon the occurrence of certain insolvency-related events or breaches by the other party. Although the Company has no separate agreement with respect to such activities, Medica has also been manufacturing the Company’s DSU in limited quantities.

The Company also entered into an agreement in December 2003, and amended in June 2005, with Membrana GmbH (“Membrana”), a manufacturer of medical and technical membranes for applications like dialysis with corporate headquarters located in Germany, to continue to produce the fiber for the OLpur MDHDF filter series. Pursuant to the agreement, Membrana is the Company’s exclusive provider of the fiber for the OLpur MDHDF filter series in the European Union as well as certain other territories through September 2009. Notwithstanding the exclusivity provisions, the Company may purchase membranes from other providers if Membrana is unable to timely satisfy the Company’s orders. If and when the volume-discount pricing provisions of the Company’s agreement with Membrana become applicable, for each period the Company will record inventory and cost of goods sold for the Company’s fiber requirements pursuant to the agreement with Membrana based on the volume-discounted price level applicable to the actual year-to-date cumulative orders at the end of such period. If, at the end of any subsequent period in the same calendar year, actual year-to-date cumulative orders entitle the Company to a greater volume-discount for such calendar year, then the Company will adjust inventory and cumulative cost of goods sold amounts quarterly throughout the calendar year to reflect the greater volume-discount. In August 2006, Membrana awarded the Company temporary pricing concessions until June 2007. We are currently negotiating with Membrana regarding pricing for purchases incurred from June 2007 to present, as well as future product pricing.

The Company is committed to use one supplier for its production of products for sale in Europe; however no minimum purchase requirements are in effect.

Registration Payment Arrangement

In September 2007, the Company issued $12.7 million and $5.3 million in convertible notes and, as partial compensation to placement agents in connection therewith, issued warrants to purchase an aggregate of 1,756,374 shares of common stock. Upon conversion of such notes in November 2007, the Company issued an aggregate of 25,847,388 shares of common stock and warrants to purchase an aggregate of 9,112,566 shares of common stock to the former holders of such notes. As part of such offering, the Company has entered into an arrangement requiring the Company to use its best efforts to file a registration statement with the SEC covering resale of the shares of common stock and for such registration statement to be declared effective on or prior to June 20, 2008 (the Effectiveness Date). If the registration statement is not declared effective by such deadline, then the investors are entitled to damages in the form of a cash payment equal to 1% of the amount of the holder’s Conversion Amount (defined as the principal amount of the note and all accrued but unpaid interest as of the Automatic Conversion date (November 14, 2007)) for each of the first ten 30-day periods after the Effectiveness Date and 2% of the amount of holder’s Conversion Amount for each 30-day period thereafter, until the registration statement is declared effective by the SEC. As of December 31, 2007, the Company does not believe that it is probable that it will incur any damages under the arrangement.

Employee Severance Agreement

During the year ended December 31, 2005, the Company expensed $318,250 for severance costs associated with the termination of the employment of Jan Rehnberg, our former Senior Vice President, Marketing and Sales. These severance expenses were reported within accrued expenses and presented as accrued severance expenses at December 31, 2005. In accordance with the terms and provisions of his employment agreement, the Company paid a lump sum severance payment of $253,856 of the balance to Mr. Rehnberg on April 19, 2006. During September 2006, the Company reversed the $64,394 residual portion of the severance accrual as it was determined during the quarter that this liability was no longer required. In 2006, the Company expensed $93,072 for severance costs associated with the termination of an employee in France.

On September 19, 2007, in connection with Mr. Fox’s resignation as Executive Chairman, Nephros and Mr. Fox entered into a Separation Agreement and Release (the “Separation Agreement”), pursuant to which the parties mutually agreed to terminate Mr. Fox’s employment with Nephros and the employment agreement between Nephros and Mr. Fox made as of July 1, 2006 (the “Employment Agreement”), effective immediately. Nephros will pay Mr. Fox an aggregate of $142,500 payable in equal installments for a period of six months after the Termination Date (as defined in the Separation Agreement). Nephros also paid to Mr. Fox

Item 8. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

There have been no changes in or disagreements with our accountants since our formation required to be disclosed pursuant to Item 304 of Regulation S-B, except that on July 16, 2007, we changed auditors as reported on our Form 8-K filed on July 16, 2007.

Item 8A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain a system of disclosure controls and procedures, as defined in Exchange Act Rule 13a-15(e),which is designed to provide reasonable assurance that information, which is required to be disclosed in our reports filed pursuant to the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), is accumulated and communicated to management in a timely manner. At the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(b). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report were not yet effective. We instituted and are continuing to implement corrective actions with respect to the deficiencies in our disclosure controls and procedures caused by an insufficient pool of resources in the accounting and finance department that limits the ability to maintain a thorough review process. The review of the quarterly financial reports, which includes detailed reconciliations of the balance sheet accounts, is supported by outside sources including independent assistance from an additional outside accounting firm which ensures adequate reporting according to U. S. GAAP and SEC reporting requirements. Additional reviews are also provided by legal counsel and the independent Audit Committee of Nephros, which has strengthened due to new member additions during the fourth quarter of 2007.

Changes in Internal Control Over Financial Reporting

During the fourth quarter of 2007, there were no significant changes in our internal control over financial reporting or in other factors that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Through the evaluation of the Sarbanes-Oxley internal control assessment, a more structured approach, including checklists, reconciliations and analytical reviews, has been implemented to reduce risk in the financial reporting process.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f), is a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;
Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and
Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable

assurance with respect to financial statement preparation and presentation. The scope of management’s assessment of the effectiveness of internal control over financial reporting includes all of our Company’s consolidated subsidiaries.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2007. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in “Internal Control-Integrated Framework.” Based on this assessment, management believes that, as of December 31, 2007, our internal control over financial reporting was not effective due to an insufficient number of resources in the accounting and finance department that does not allow for a thorough review process. Management identified a material weakness in internal control over financial reporting, due to an insufficient number of resources in the accounting and finance department. Due to the pervasive effect of the lack of resources, including a lack of resources that are appropriately qualified in the areas of U.S. GAAP and SEC reporting, and the potential impact on the financial statements and disclosures and the importance of the annual and interim financial closing and reporting process, in the aggregate, there is more than a remote likelihood that a material misstatement of the annual financial statements would not have been prevented or detected. We have designed the following steps to be implemented:

Develop procedures to implement a formal monthly closing calendar and process and hold monthly meetings to address the monthly closing process;
Establish a detailed timeline for review and completion of financial reports to be included in our Forms 10-QSB and 10-KSB;
Enhance the level of service provided by outside accounting service providers to further support and supplement our internal staff in accounting and related areas;
Seek additional staffing to provide additional resources for internal preparation and review of financial reports; and
Employ the use of appropriate supplemental SEC and U.S. GAAP checklists in connection with our closing process and the preparation of our Forms 10-QSB and 10-KSB.

The implementation of these remediation plans has been initiated and will continue during fiscal 2008. The material weakness will not be considered remediated until the applicable remedial procedures are tested and management has concluded that the procedures are operating effectively.

Item 8A(T). Controls and Procedures

This annual report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit us to provide only management’s report in this annual report.

The discussion of internal controls and procedures contained in Item 8A is hereby incorporated by reference into this Item 8A(T).

Item 8B. Other Information

Not applicable.

NEPHROS, INC.
 
Warrant for the Purchase of Shares of
Common Stock
 
No. L-1 
January 18, 2006
 
FOR VALUE RECEIVED, NEPHROS, INC., a Delaware corporation (the “ Company ”), hereby certifies that Marty Steinberg, Esq., as Court-appointed Receiver for Lancer Offshore, Inc.,   or his registered assigns (the “ Holder ”) is entitled to purchase from the Company, subject to the provisions of this Warrant (the “ Warrant ”), at any time on or after the date hereof (the “Initial Exercise Date” ), and prior to 12:01 A.M., New York City time, on January 18, 2009 (the “ Termination Date ”), 21,308   fully paid and non-assessable shares of the Common Stock, $.001 par value, of the Company (“Common Stock”), at an exercise price of $1.50 per share of Common Stock for an aggregate exercise price of thirty-one thousand nine hundred sixty-two dollars ($31,962.00) (the aggregate purchase price payable for the Warrant Shares hereunder is hereinafter sometimes referred to as the “ Aggregate Exercise Price ”). The number of shares of Common Stock to be received upon exercise of this Warrant and the price to be paid for each share of Common Stock are subject to possible adjustment from time to time as hereinafter set forth. The shares of Common Stock or other securities or property deliverable upon such exercise as adjusted from time to time is hereinafter sometimes referred to as the “Warrant Shares.” The exercise price of a share of Common Stock in effect at any time and as adjusted from time to time is hereinafter sometimes referred to as the “ Per Share Exercise Price. ” The Per Share Exercise Price is subject to adjustment as hereinafter provided; in the event of any such adjustment, the number of Warrant Shares shall also be adjusted, by dividing the Aggregate Exercise Price by the Per Share Exercise Price in effect immediately after such adjustment. The Aggregate Exercise Price is not subject to adjustment except to the extent of any partial exercise of this Warrant.
 
1.   Exercise of Warrant .
 
(a)   This Warrant may be exercised in whole or in part, at any time by its holder commencing on the Initial Exercise Date and prior to the Termination Date by presentation and surrender of this Warrant, together with the duly executed subscription form attached at the end hereof, at the address set forth in Subsection 8(a) hereof, together with payment, by certified or official bank check or wire transfer payable to the order of the Company, of the Aggregate Exercise Price or the proportionate part thereof if exercised in part.
 
 
 

 
(b)   If this Warrant is exercised in part only, the Company shall, upon presentation of this Warrant upon such exercise, execute and deliver (along with the certificate for the Warrant Shares purchased) a new Warrant evidencing the rights of the Holder hereof to purchase the balance of the Warrant Shares purchasable hereunder upon the same terms and conditions as herein set forth. Upon proper exercise of this Warrant, the Company promptly shall deliver certificates for the Warrant Shares to the Holder duly legended as authorized by the subscription form. No fractional shares or scrip representing fractional shares shall be issued upon exercise of this Warrant; provided that the Company shall pay to the Holder of the Warrant cash in lieu of such fractional shares.
 
(c)   The certificates representing the Warrant Shares shall bear the following legend:
 
THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO SUCH SECURITIES UNDER THE SECURITIES ACT OR AN EXEMPTION FROM THE SECURITIES ACT. ANY SUCH TRANSFER MAY ALSO BE SUBJECT TO COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS AND THE LAWS OF OTHER APPLICABLE JURISDICTIONS.
 
2.   Reservation of Warrant Shares; Fully Paid Shares; Taxes . The Company hereby represents that it has, and until expiration of this Warrant agrees that it shall, reserve for issuance or delivery upon exercise of this Warrant, such number of shares of the Common Stock as shall be required for issuance and/or delivery upon exercise of this Warrant in full, and agrees that all Warrant Shares so issued and/or delivered will be validly issued, fully paid and non-assessable, and further agrees to pay all taxes (other than income taxes) and charges that may be imposed upon such issuance and/or delivery. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue or delivery of Common Stock (or other securities or assets) in a name other than that in which the Warrants so exercised were registered, and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Company the amount of such tax or has established, to the satisfaction of the Company, that such tax has been paid.
 
3.   Protection Against Dilution .
 
(a)   In case the Company shall hereafter (i) pay a dividend or make a distribution on its capital stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares or (iv) issue by reclassification of its Common Stock any shares of capital stock of the Company (each of (i) through (iv) an “Action”), the Per Share Exercise Price shall be adjusted to be equal to a fraction, the numerator of which shall be the Aggregate Exercise Price and the denominator of which shall be the number of shares of Common Stock or other capital stock of the Company that the Holder would have held (solely as a result of the exercise of this Warrant and the operation of such Action) immediately following such Action if this Warrant had been exercised immediately prior to such Action. An adjustment made pursuant to this Subsection 3(b) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification.
 
 
2

 
(b)   In the event of any capital reorganization or reclassification not otherwise covered in this Section 3, or any consolidation or merger to which the Company is a party other than a merger or consolidation in which the Company is the continuing corporation, or in case of any sale or conveyance to another entity of the property of the Company as an entirety or substantially as an entirety, or in the case of any statutory exchange of securities with another corporation (including any exchange effected in connection with a merger of a third corporation into the Company), the Holder of this Warrant shall have the right thereafter to receive on the exercise of this Warrant the kind and amount of securities, cash or other property which the Holder would have owned or have been entitled to receive immediately after such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance had this Warrant been exercised immediately prior to the effective date of such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section 3 with respect to the rights and interests thereafter of the Holder of this Warrant to the end that the provisions set forth in this Section 3 shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant. The above provisions of this Subsection 3(b) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances.
 
(c)   Whenever the Per Share Exercise Price payable upon exercise of this Warrant is adjusted pursuant to this Section 3, the number of shares of Common Stock underlying this Warrant shall simultaneously be adjusted to equal the number obtained by dividing the Aggregate Exercise Price (as the same shall be reduced to the extent of any partial exercise of this Warrant) by the adjusted Per Share Exercise Price.
 
(d)   If, as a result of an adjustment made pursuant to this Section 3, the Holder shall become entitled to receive, upon exercise of the Warrant, shares of two or more classes of capital stock or shares of Common Stock and other capital stock of the Company, the Board of Directors (whose determination shall be conclusive) shall determine the allocation of the adjusted Per Share Exercise Price between or among shares or such classes of capital stock or shares of Common Stock and other capital stock.
 
4.   Limited Transferability . This Warrant may not be sold, transferred, assigned or hypothecated by the Holder except in compliance with the provisions of the Act and the applicable state securities “blue sky” laws, and is so transferable only upon the books of the Company which it shall cause to be maintained for such purpose. The Company may treat the registered Holder of this Warrant as he or it appears on the Company’s books at any time as the Holder for all purposes.
 
 
3

 
5.   Loss, etc., of Warrant . Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and of indemnity reasonably satisfactory to the Company (which may include a bond), if lost, stolen or destroyed, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver to the Holder a new Warrant of like date, tenor and denomination.
 
6.   Investment Intent .
 
(a)   The Holder represents, by accepting this Warrant, that it understands that this Warrant and any securities obtainable upon exercise of this Warrant have not been registered for sale under Federal or state securities laws and are being offered and sold to the Holder pursuant to one or more exemptions from the registration requirements of such securities laws. The Holder is an “accredited investor” within the meaning of Regulation D under the Securities Act of 1933, as amended (the “Act”). In the absence of an effective registration of such securities or an exemption therefrom, any certificates for such securities shall bear the legend set forth on the first page hereof. The Holder understands that it must bear the economic risk of its investment in this Warrant and any securities obtainable upon exercise of this Warrant for an indefinite period of time, as this Warrant and such securities have not been registered under Federal or state securities laws and therefore cannot be sold unless subsequently registered under such laws, unless as exemption from such registration is available.
 
(b)   The Holder, by its acceptance of its Warrant, represents to the Company that it is acquiring this Warrant and will acquire any securities obtainable upon exercise of this Warrant for its own account for investment and not with a view to, or for sale in connection with, any distribution thereof in violation of the Act. The Holder agrees that this Warrant and any such securities will not be sold or otherwise transferred unless (i) a registration statement with respect to such transfer is effective under the Act and any applicable state securities laws or (ii) such sale or transfer is made pursuant to one or more exemptions from the Act.
 
7.   Status of Holder . This Warrant does not confer upon the Holder any right to vote or to consent to or receive notice as a stockholder of the Company, as such, in respect of any matters whatsoever, or any other rights or liabilities as a stockholder, prior to the exercise hereof.
 
8.   Notices . No notice or other communication under this Warrant shall be effective unless, but any notice or other communication shall be effective and shall be deemed to have been given if, the same is in writing and is mailed by first-class mail, postage prepaid, addressed to:
 
(a)   the Company c/o Audubon Business and Technology Center, Columbia-Presbyterian Medical Center, 3960 Broadway, 4th Floor, New York, NY 10032, Attention: President, or such other address as the Company has designated by notice to the Holder; or

9.   Headings . The headings of this Warrant have been inserted as a matter of convenience and shall not affect the construction hereof.
 
10.   Applicable Law . This Warrant shall be governed by and construed in accordance with the law of the State of New York without giving effect to principles of conflicts of law thereof.
 
11.   Amendments .     This Warrant may be amended only by mutual written agreement of the Company and the Holder, and the Company may take any action herein prohibited or omit to take any action herein required to be performed by it, and any breach of any covenant, agreement, warranty or representation may be waived, only if the Company has obtained the written consent or waiver of the Holder.

WHEREAS, Licensee desires to acquire a license to use space at the Audubon Business and Technology Center in the Mary Woodard Lasker Building (the “ Building ”), located at 3960 Broadway in the City, County and State of New York; and
 
WHEREAS, Licensor is agreeable to granting to Licensee a license to use space in the Building on the terms and conditions hereinafter set forth.
 
NOW, THEREFORE, the parties agree as follows:
 
1.   LICENSE . Licensor does hereby grant to Licensee a nontransferable license to use certain space (the “ Licensed Space ”) on the 4th floor of the Building as more particularly shown on Exhibit “A” annexed hereto and made a part hereof.
 
2.   TERM . The term of this Agreement (the “Term” ) shall commence on October 1, 2007 (the “Commencement Date” ), and shall, unless sooner terminated in accordance with the terms hereof or pursuant to law, continue until September 30, 2008 (the “Expiration Date” ).
 
3.   CONDITION OF PREMISES . Licensee acknowledges that it has inspected the Licensed Space and agrees to take the Licensed Space “as is” without any work being done therein by Licensor, and without any obligation upon Licensor to make any contribution toward or to assume the performance of any work in order to prepare the Licensed Space for use by Licensee. Licensee acknowledges that all materials, fixtures and equipment, if any, which Licensor may elect to make available for Licensee’s use are, and shall be and remain, the property of Licensor. Licensee acknowledges that Licensor has not made and does not make any representations or warranties to Licensee, whether directly or indirectly, with respect to the Licensed Space or the use or proposed use thereof by Licensee.
 
4.   USE . Licensee shall use the Licensed Space solely as laboratory and office space. Within a month of taking occupancy of the Licensed Space, Licensee shall submit to Licensor for approval, Licensee’s Regulatory Compliance Plan (the “ Plan ”) which Plan shall (a) identify those activities of and materials to be used by Licensee which are or may be subject to Environmental Legal Requirements (as hereinafter defined) or other Legal Requirements (as hereinafter defined) and (b) detail Licensee’s plans and procedures for compliance with Environmental Legal Requirements, Legal Requirements and Insurance Requirements (as hereinafter defined) as to each specific regulated material and activity. From time to time, at any time during the Term, Licensee shall revise the Plan to reflect any changes in its activities, materials, Environmental Legal Requirements, Legal Requirements or Insurance Requirements. The Plan and all such revisions shall be subject to Licensor’s prior review and approval.
 
5.   FEE .     (a) Licensee agrees to pay to Licensor as and for the use of the Licensed Space during the Term an annual amount (the “ License Fee ”) as set forth on Exhibit “B” annexed hereto and made a part hereof. The License Fee shall be paid in monthly installments as set forth on Exhibit B , in advance, on the first day of each and every month during the Term, without offset or deduction except that the first monthly installment shall be paid upon execution hereof. If the Commencement Date shall occur on a day other than the first day of a calendar month or if the Expiration Date shall occur on a day other than the last day of a calendar month, the License Fee for such calendar month shall be appropriately prorated.
 
(b)   All sums of money as shall become due and payable by Licensee to Licensor hereunder (collectively, “ License Consideration ”) shall be paid to Licensor within ten (10) days after receipt by Licensee of bills or notice from Licensor to Licensee identifying the same. If Licensee shall fail to pay any License Consideration within such ten (10) day period, or shall fail to pay any installment of the License Fee within ten (10) days after it is due, such unpaid amounts shall bear interest at the rate per annum equal to the lesser of (i) two percent (2%) plus the base rate charged by Citibank, N.A. and in effect during the period such amounts are due and unpaid and (ii) the maximum rate permitted by law, from the due date of such payment to the date paid to Licensor.

(c)   If Licensee shall default in performing any term, covenant or condition of this Agreement which shall involve the expenditure of money by Licensee to third parties, and such default shall continue beyond applicable notice and grace period, Licensor may (but shall not be obligated to) make such payment or, on behalf of Licensee, expend such sum as may be necessary to perform or fulfill such term, covenant or condition. All sums so paid or expended by Licensor shall be deemed to be License Consideration and shall be payable by Licensee to Licensor in accordance with Paragraph 5(b) above. No such payment or expenditure by Licensor shall be construed as a waiver of Licensee’s default or of Licensee’s obligation to perform any term, covenant or condition of this License Agreement nor shall it affect any other right or remedy of Licensor under this License Agreement.
 
6.   COVENANTS AND WARRANTIES . Licensee covenants and warrants:
 
(a)   at Licensee’s sole cost and expense, to keep and maintain the Licensed Space in good order and condition, to notify Licensor of any needed repairs, which repairs shall be performed by Licensor at Licensee’s sole cost and expense, and to quit and surrender the Licensed Space to Licensor upon the expiration or earlier termination of this Agreement in as good and proper order and condition as at the Commencement Date, reasonable wear and tear excepted;

Upon receipt of such notice and back-up documentation, Licensor shall review such request, provided, however, that Licensor shall, in its sole and absolute discretion, have no obligation to consent to Licensee’s request.

(d)   Such different or the same types of insurance set forth above in such amounts as may from time to time be reasonably required by Licensor against such other insurable hazards as at the time are commonly insured against in the case of premises similarly situated.
 
8.   DAMAGE AND DESTRUCTION . (a) If the Licensed Space or any part thereof shall be damaged by fire or other casualty, Licensee shall give immediate notice thereof to Licensor and this Agreement shall continue in full force and effect, unless Licensor shall elect to terminate this Agreement as set forth below. In the event that this Agreement shall not be so terminated, Licensor shall restore the Licensed Space at Licensor’s expense and the Licensee Fee and License Consideration shall be proportionately abated during the period in which Licensor is restoring the Licensed Space if all or any portion of the Licensed Space is unusable by Licensee for the purposes set forth in Paragraph 4 above during such period. Licensee’s liability for the full amount of the Licensee Fee and License Consideration shall resume five (5) days after written notice from Licensor that the Licensed Space is substantially ready for Licensee’s occupancy.
 
(b)   In the event that the Licensed Space is rendered wholly or substantially unusable (whether or not the Licensed Space has been damaged in whole or in part) by fire or other casualty (of which fact Licensor shall be the sole judge), Licensor may elect to terminate this Agreement by written notice to Licensee given within sixty (60) days after such fire or casualty, specifying the date for the expiration of this Agreement, which shall be no more than thirty (30) days after the giving of such notice.
3

(c)   If Licensor shall fail within thirty (30) days after notice by Licensee to Licensor of such casualty to restore the damaged portion of the Licensed Space to substantially the condition existing prior to such casualty, Licensee may elect to terminate this Agreement by written notice to Licensor given prior to completion of such restoration, specifying the date for the expiration of this Agreement, which shall be no more than thirty (30) days after the giving of such notice.
 
(d)   Nothing contained herein shall relieve Licensee from liability that may exist as a result of damage from fire or other casualty. Notwithstanding the foregoing, each party shall look first to any insurance in its favor before making any claim against the other party for recovery for loss or damage resulting from fire or other casualty, and to the extent that such insurance is in force and collectible and to the extent permitted by law, Licensor and Licensee each hereby releases and waives all rights of recovery against the other or anyone claiming through or under the other, by way of subrogation or otherwise. The foregoing release and waiver shall be in force only if both parties’ insurance policies contain a clause providing that such a release or waiver shall not invalidate the insurance and also provided that such clause can be obtained without additional premium; it being agreed, however, that the party whose insurance carrier requires such additional premium shall notify the other party thereof and such other party shall have the right to pay such additional premium.
 
(e)   Licensee acknowledges that Licensor will not carry insurance on the improvements, furniture, furnishings, fixtures and equipment and other personal property required to be insured by Licensee pursuant to Paragraph 7(a) above and Licensor will not be obligated to repair any damage thereto or replace the same.
 
(f)   Licensee hereby waives the provisions of Section 227 of the Real Property Law and agrees that the provisions of this Paragraph 8 shall govern and control in lieu thereof.
 
9.   ALTERATIONS . Licensee shall not make any improvements, additions, alterations or other changes, except for cosmetic and decorative alterations, to the Licensed Space, without the prior written consent of Licensor in each instance.
 
10.   UTILITIES AND SERVICES .   (a) Licensee shall have 24-hour, 7-day-a-week access to the Building and passenger elevator service to the Licensed Space. Freight elevator service shall be available on business days from 8 a.m. to 4 p.m. If Licensee shall require freight elevator service during any other time, Licensor shall furnish same provided that Licensee gives Licensor advance notice and that Licensee pays, on demand, as License Consideration, Licensor’s then established charges therefor.
 
(b)   Licensor shall provide electric energy to the Licensed Space. Licensee shall pay Licensor for electricity consumed by Licensee in the Licensed Space. Licensor will permit the electrical risers, feeders and wiring in the Building serving the Licensed Space to be used by Licensee for such purpose to the extent that they are available, suitable, safe and within the plan and design capacities of the Building. Licensee shall not be required to pay Licensor more than the amount calculated by applying to the measured demand and/or usage of electrical current in or furnished to the Building, the average rate per unit of measurement, inclusive of applicable taxes, surcharges, time of day and other charges, payable by Licensor for electrical current furnished to the Licensed Space by the utility company serving the Building. Should any tax or charge in the nature of a tax be imposed upon Licensor’s receipts from the sale or resale of electrical current to the Licensed Space, then the pro rata share thereof allocable to the electrical current furnished to the Licensed Space shall be passed on to and paid by Licensee. Bills for Licensee’s usage of electrical current shall be paid within ten (10) days by Licensee as License Consideration. If due to any change in Legal Requirements Licensor shall not be permitted to provide electric energy to the Licensed Space, then this Agreement shall not be affected and Licensee shall arrange to obtain electric energy directly from the public utility company furnishing electrical service to the Building. In such event Licensee shall no longer pay Licensor for electricity consumed.
 
(c)   Licensee’s use of electrical energy shall never exceed the capacity of the then existing risers or wiring installation, in each case. In order to insure that such electrical capacity is not exceeded and to avert possible adverse effect upon the Building’s electrical system, Licensee shall not, without the prior written consent of Licensor, make or perform or permit any alteration to wiring installations or other electrical facilities in or serving the Licensed Space or any additions to the electrical fixtures, machines or equipment or appliances in the Licensed Space. Licensor shall not be obligated to consent to any such alteration or installation if, in Licensor’s judgment, the same are unnecessary or will cause permanent damage or injury to the Building, the Building equipment or the Licensed Space or will cause or create a hazardous condition or entail excessive or unreasonable alterations, repairs or expense or interfere with or disturb other tenants or occupants. Only rigid conduit or such other wiring or conduit as shall not violate Legal Requirements will be allowed.
4

(d)   Licensor shall have no liability to Licensee for any loss, damage or expense which Licensee may sustain or incur by reason of any change, failure, inadequacy or defect in the supply or character of the electrical energy or emergency generator back-up power furnished to the Licensed Space or if the quantity or character of the electrical energy is no longer available or suitable for Licensee’s requirements, except for any actual damage suffered by Licensee by reason of any such failure, inadequacy or defect caused by Licensor’s gross negligence, and then only after actual notice thereof.
 
(e)   Licensor shall make available from the public water supply to a point or points at or near the Licensed Space selected by Licensor such quantities of domestic cold and hot water as Licensor, in its sole and absolute judgment, deems adequate for normal laboratory and ordinary lavatory, cleaning and drinking purposes. In the event that the Licensee requires hot or cold water for any purposes other than those specified in the preceding sentence, including, but not limited to high volume laboratory usage, Licensee shall pay Licensor, as License Consideration, for water consumed, as shown on separate submeters for cold and hot water maintained by Licensee, together with all sewer charges and any other rent, tax, levy or charge based thereon which now or hereafter is assessed, imposed or a lien upon the Licensed Space or the Building, as and when bills are rendered. Payment for cold water shall be at the rate charged by the City for cold water. Payment for hot water shall be at three (3) times such rate. Licensor shall have no liability to Licensee for any loss, damage or expense which Licensee may sustain or incur if the quantity or character of water service changes or is no longer available or suitable for Licensee’s purposes.
 
(f)   Licensee shall notify Licensor, within ten (10) days after the Commencement Date, of the water meter number of each water meter serving the Licensed Space and whether such meter is for hot water or cold water. If any such meter is installed subsequent to the taking of possession by Licensee, then Licensee shall notify Licensor of such information within ten (10) days after such installation.
 
(g)   Licensor shall make available to a point or points at or near the Licensed Space such piping, systems, equipment and facilities as Licensor, in its sole and absolute judgment, deems adequate to provide gas service for normal laboratory consumption. Licensee shall pay Licensor, as License Consideration, for any and all gas consumed. Meters may be installed and maintained by Licensor, at Licensee’s sole cost and expense. The rates charged by Licensor to Licensee for gas consumption shall not exceed the rates charged by the utility company providing such service. Payment for gas consumed by Licensee in the Licensed Space shall be made by Licensee as License Consideration within ten (10) days of Licensor’s bill therefor. Licensee shall make no alteration, addition or repair to the gas connection, installations, equipment and/or facilities without the prior written consent of Licensor in each instance. Licensor shall have no liability to Licensee for any loss, damage or expense which Licensee may sustain or incur if the quantity or character of the gas service is changed or is no longer available or suitable for Licensee’s requirements.
 
(h)   Licensor shall, without additional charge to Licensee, supply hot water for heat, and chilled water for air conditioning and ventilation to the Licensed Space through existing Building risers, radiators and air handlers during appropriate seasons as may reasonably be required by Licensee for ambient heating and cooling seven days a week, 24 hours a day.
 
(i)   Licensor shall provide cleaning services in accordance with the specifications annexed hereto as Exhibit D and made a part hereof.
 
(j)   Licensor shall supply compressed air and vacuum air to a point or points near the Licensed Space in quantities which Licensor deems adequate for normal laboratory purposes. If Licensee shall require additional compressed air and vacuum air in excess of that which Licensor deems adequate for the purposes set forth herein, Licensor shall furnish same at Licensor’s then established rates and same shall be payable by Licensee, as License Consideration, within ten (10) days of Licensor’s bill therefor.
 
(k)   Licensee shall be responsible for the proper storage and removal from the Licensed Space and the Building and the disposal of all of Licensee’s Hazardous Materials. Licensee shall contract for the disposal of Hazardous Materials, at Licensee’s cost and expense, with vendors approved by Licensor, in its sole and absolute discretion. In contracting with any such vendor, Licensor shall endeavor to ensure that Licensee shall receive the benefit of any volume discount granted to Licensor by such vendor.
 
11.     NO LIENS .   (a) Licensee shall have no power to do any act or to make any contract which may create or give rise to any lien, mortgage or other encumbrance on the estate of Licensor or any interest of Licensor or Licensee in the Licensed Space or the Building.
5

(b)   If any lien shall at any time be filed against the Licensed Space or the Building by reason of any work, labor, services or materials done for, or supplied to, or claimed to have been done for, or supplied to, Licensee or anyone holding the Licensed Space through or under Licensee, Licensee shall cause the same to be discharged of record or adequately bonded (unless otherwise secured to the satisfaction of Licensor) within thirty (30) business days after the date Licensee has received notice of the filing of such lien. If Licensee shall fail to do so, then, Licensor may, but shall not be obligated to, procure the discharge of the same either by paying the amount claimed to be due, by deposit in a court of competent jurisdiction or by bonding, and Licensor may compel the prosecution of an action for the foreclosure of such lien by the lienor and pay the amount of the judgment, if any, in favor of the lienor with interest, costs and allowances. Any amount paid or deposited by Licensor for any such purpose, and all other expenses of Licensor, including reasonable attorney’s fees and disbursements, shall be deemed to be License Consideration and shall be paid on demand by Licensee.
 
12.   SUBORDINATION . Licensee acknowledges that this Agreement is subject and subordinate to any and all ground or underlying leases and to all mortgages which may now or hereafter affect such leases or the Building and to all renewals, modifications, consolidations, replacements and extensions of any such underlying leases and mortgages.
 
13.   NO ASSIGNMENT OR USE BY THIRD PARTIES . Licensee shall not permit the use or occupancy of all or any part of the Licensed Space by any third party nor assign its rights nor delegate its duties under this Agreement. For purposes of this Paragraph 13, a change in control of Licensee shall be deemed an assignment hereunder. “ Change in control ” shall be deemed to mean a change (by transfer or otherwise) in either (a) ownership of fifty percent (50%) or more of all of the voting stock of a corporation or fifty percent (50%) or more of all of the legal and equitable interest in a partnership or other business entity or (b) the possession of the power directly or indirectly to direct or cause the direction of management and policy of a corporation, partnership or other business entity, whether through the ownership of voting securities, by contract, common directors or officers, the contractual right to manage the business affairs of any such corporation, partnership or business entity, or otherwise.
 
14.   BROKERAGE . Licensee represents to Licensor that there is no broker, finder, consultant or similar person acting on behalf of Licensee entitled to a commission, fee or other compensation in connection with the consummation of this Agreement and no conversations or prior negotiations were had by Licensee or anyone acting on behalf of Licensee with any broker, finder, consultant or similar person concerning the use of the Licensed Space except for such broker(s), if any, set forth in Exhibit “E” annexed hereto and made a part hereof. Licensee hereby agrees to pay the commission of any such broker, finder, consultant or similar person. Licensee shall indemnify and hold Licensor harmless from and against all liability arising from any claims for brokerage commissions, finder’s fees or other compensation resulting from or arising out of any alleged conversations, negotiations or actions had by Licensee or anyone acting on behalf of Licensee with any broker, finder, consultant or similar person. The provisions of this Paragraph 14 shall survive the termination of this Agreement.
 
15.   ACCESS TO THE PREMISES . Licensor and Licensor’s agents and employees shall have the right to enter the Licensed Space for any reasonable purpose, including, without limitation, for purposes of inspection and repair and monitoring Licensee’s activities for compliance with the Environmental Legal Requirements, Legal Requirements, Insurance Requirements and the Plan. Except in cases of emergency or where required for effective inspection and monitoring for health and safety purposes, Licensor shall provide Licensee with one (1) day prior notice of its intention to enter the Licensed Space, which notice may be given orally or by telephone provided that it shall be followed by written notice received by Licensee on the same day as such oral or telephone notice. Licensee shall acknowledge such notice “received” by signing a copy thereof and returning it to Licensor within twenty-four (24) hours of Licensee’s receipt, and Licensor may enter the Licensed Space upon receipt of such copy acknowledged by Licensee or upon expiration of such 24-hour period, whichever occurs first.
 
16.   INDEMNIFICATION . Licensee agrees that Licensee shall make no claim against Licensor for any injury or damage to Licensee or to any other person(s) or for any damage to, or loss (by theft or otherwise) of, any property of Licensee or of any other person. Licensee further agrees to indemnify and save Licensor harmless from and against any and all claims by or on behalf of any person(s), firm(s) or corporation(s) arising from the conduct or management of or from any work or thing whatsoever done in, on or about the Licensed Space during the Term, and to indemnify and save Licensor harmless from and against any and all claims arising from any condition of the Licensed Space due to or arising from any act or omission or negligence of Licensee or any of its agents, contractors, servants, employees, licensees or invitees, and from and against all liabilities, costs and expenses (including, without limitation, attorneys’ fees and disbursements) incurred in or in connection with any such claim or claims or action or proceeding brought thereon; and in case any action or proceeding shall be brought against Licensor by reason of any such claim, Licensee upon notice from Licensor agrees to resist or defend such action or proceeding and to employ counsel therefor reasonably satisfactory to Licensor.

20.   TERMINATION .

21.   SECURITY DEPOSIT . (a) Licensee has deposited the sum of $ 26,719.10 with Licensor as security for the full and punctual performance by Licensee of all of the terms of this Agreement, to be deposited by Licensor in an interest-bearing account of Licensor’s choosing. In the event Licensee defaults in the performance of any of the terms of this Agreement, Licensor may use or retain the whole or any part of the security deposited to the extent required for the payment of any fees or for any sum that Licensor may expend or may be required to expend by reason of Licensee’s default, including any damages or deficiency in the relicensing or letting of the Licensed Space, whether accruing before or after summary proceedings or other re-entry by Licensor. In the case of every such use or retention, Licensee shall, on demand, pay to Licensor the sum so used or retained which sum shall be added to the security deposited so that the same shall be replenished to its former amount. In the event any bankruptcy, insolvency, reorganization or other creditor-debtor proceedings shall be instituted by or against Licensee, or its successors or assigns, the security deposited shall be deemed to be applied first to the payment of such fees due Licensor for all periods prior to the institution of such proceedings and the balance, if any, of the security deposited may be retained by Licensor in partial liquidation of Licensor’s damages. If Licensee shall fully and punctually comply with all of the terms of this Agreement, the security deposited plus any accrued interest thereon (less an amount equal to one percent per annum on the security deposited not to exceed the amount of any interest earned on the security deposited for Licensee’s administrative costs in connection with the security deposited) shall be returned to Licensee after the termination of this Agreement and delivery of exclusive possession of the Licensed Space to Licensor in compliance with the provisions of this Agreement.

(d)   Licensee shall not assign or encumber or attempt to assign or encumber the security deposited and neither Licensor nor its successors or assigns shall be bound by any such assignment, encumbrance or attempted assignment or encumbrance.
 
(e)   In the event of a sale or lease of the Building, Licensor shall have the right to transfer the security deposited to the vendee or lessee and Licensor shall ipso   facto be released by Licensee from all liability for the return of the security deposited and Licensee shall look solely to the new licensor for the return of the security deposited. The provisions hereof shall apply to every transfer or assignment made of the security deposited to a new licensor.
 
(f)   In the event that the License Fee shall increase pursuant to the terms of this Agreement, the amount of security deposited shall be increased so that at all times the security deposited (exclusive of interest) shall equal one-sixth of the current annual License Fee. Licensee shall immediately deposit with Licensor the difference between the amount being held by Licensor as security (exclusive of interest) and the amount required to be deposited pursuant to this Subparagraph 21(f).
 
22.   CAPTIONS . The captions of the Paragraphs of this Agreement are inserted only as a matter of convenience and for reference and in no way define, limit or describe the scope of this Agreement nor the intent of any provision thereof.
 
23.   RELOCATION .

24.   MISCELLANEOUS . (a) The covenants and agreements contained in this Agreement shall apply to, inure to the benefit of, and be binding upon Licensor and Licensee and upon their respective successors and permitted assigns.
 
(b)   This Agreement may not be changed, cancelled or discharged orally, but only by an agreement in writing and signed by the party against whom enforcement of any waiver, change, modification or discharge is sought. All understandings and agreements between Licensor and Licensee are merged in this Agreement which represents the entire agreement between the parties and which fully and completely sets forth all terms and conditions of the transactions embodied in this Agreement.
 
(c)   If any term or provision of this Agreement or any portion of a term or provision of this Agreement or the application of any such term or condition to any person or circumstance shall, to any extent, be invalid or unenforceable, the remainder of this Agreement, or the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected, and each term and provision of this Agreement shall be valid and be enforced to the fullest extent permitted by law.
8

(d)   This Agreement shall be construed in accordance with, and governed by, the laws of the State of New York applicable to agreements made and performed in the State of New York.
 
25.   NO LANDLORD - TENANT RELATIONSHIP . Licensee hereby acknowledges that Licensee acquires no rights as a tenant of the Licensed Space and that no landlord-tenant relationship is created hereby.
 
26.   JURISDICTION .
