NEPHROS, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

1.  Basis of Presentation and Going Concern

Interim Financial Information

The accompanying unaudited condensed consolidated interim financial statements of Nephros, Inc. and its wholly owned subsidiary, Nephros International Limited (collectively, the “Company” or “Nephros”) should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s 2012 Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 4, 2013. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 and Article 10 of Regulation S-X. Accordingly, since they are interim statements, the accompanying condensed consolidated financial statements do not include all of the information and notes required by GAAP for a complete financial statement presentation. The condensed consolidated balance sheet as of December 31, 2012 was derived from the Company’s audited consolidated financial statements but does not include all disclosures required by GAAP. In the opinion of management, the interim condensed consolidated financial statements reflect all adjustments consisting of normal, recurring adjustments that are necessary for a fair presentation of the financial position, results of operations and cash flows for the condensed consolidated interim periods presented. Interim results are not necessarily indicative of results for a full year. Certain reclassifications were made to the prior year’s amounts to conform to the 2013 presentation. All significant intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amount of revenues and expenses, during the reporting period. Actual results could differ materially 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 Company’s condensed consolidated interim financial statements do not include any adjustments that might result from the outcome of this uncertainty.

The Company has incurred significant losses in operations in each quarter since inception. For the three months ended March 31, 2013 and 2012, the Company has incurred net losses of $1,242,000 and $557,000, respectively. 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, its results of operations and financial condition will be materially and adversely affected.

On June 27, 2011, the Company entered into a License Agreement,  effective July 1, 2011, with Bellco S.r.l., as licensee (“Bellco”), an Italy-based supplier of hemodialysis and intensive care products, for the manufacturing, marketing and sale of Nephros’ patented mid-dilution dialysis filters.  This Agreement provides the Company with payments of €500,000, €750,000, and €600,000 on July 1, 2011, January 15, 2012 and January 15, 2013, respectively.  All payments have been received.  Beginning on January 1, 2015 through and including December 31, 2016, Bellco will pay to Nephros a royalty based on the number of units of products sold per year in the territory as follows: for the first 103,000 units sold,  €4.50 per unit; thereafter, €4.00 per unit.   Anticipated payments from this License Agreement will be a positive source of cash flow to the Company.

On February 4, 2013, the Company issued a senior secured note (“Senior Secured Note”) to Lambda Investors LLC in the principal amount of $1.3 million.   In addition, on March 4, 2013, the Company filed an S-1 in connection with a $3.0 million rights offering (“Rights Offering”) of common stock. For a more detailed discussion of the terms of the Senior Secured Note and the Rights Offering, see Note 9, Senior Secured Note and Note 11, Subsequent Events, respectively.

There can be no assurance that the Company’s future cash flow will be sufficient to meet its obligations and commitments. If the Company is unable to generate sufficient cash flow from operations in the future to service its commitments the Company will be required to adopt alternatives, such as seeking to raise debt or equity capital, curtailing its planned activities or ceasing its 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 the Company to continue to satisfy its capital requirements.

2.  Concentration of Credit Risk

For the three months ended March 31, 2013 and 2012, the following customers accounted for the following percentages of the Company’s sales, respectively.

Customer	2013			2012
A		34	%		32	%
B		34	%		25	%
C		18	%		9	%
D		0	%		22	%

As of March 31, 2013 and December 31, 2012, the following customers accounted for the following percentages of the Company’s accounts receivable, respectively. 

Customer	2013			2012
A		0	%		85	%
B		91	%		4	%

3.  Revenue Recognition

Revenue is recognized in accordance with Accounting Standards Codification ("ASC") Topic 605. Four basic criteria must be met before revenue can be recognized: (i) persuasive evidence that an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed or determinable; and (iv) collectability is reasonably assured.

The Company recognizes revenue related to product sales when delivery is confirmed by its external logistics provider and the other criteria of ASC Topic 605 are met. Product revenue is recorded net of returns and allowances. All costs and duties relating to delivery are absorbed by Nephros. Shipments for all products are currently received directly by the Company’s customers.

Deferred revenue on the accompanying March 31, 2013 condensed consolidated balance sheet is approximately $1,239,000 and is related to the License Agreement with Bellco which is being deferred over the remainder of the expected obligation period. The Company has recognized approximately $1,220,000 of revenue related to this license agreement to date and approximately $175,000 for the three months ended March 31, 2013.

4.  Stock-Based Compensation

The Company accounts for stock option grants to employees and non-employee directors under the provisions of ASC 718, Stock Compensation.  ASC 718 requires the recognition of the fair value of stock-based compensation in the statement of operations.  In addition, the Company accounts for stock option grants to consultants under the provisions of ASC 505-50, Equity-Based Payments to Non-Employees, and as such, these stock options are revalued at each reporting period through the vesting period.

The fair value of stock option awards is estimated using a Black-Scholes option pricing model.  The fair value of stock-based awards is amortized over the vesting period of the award using the straight-line method.     

There were no stock options granted by the Company during the three months ended March 31, 2013 to employees, non-employee directors or consultants.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

4.  Stock-Based Compensation (continued)

Stock-based compensation expense was approximately $111,000 and $60,000 for the three months ended March 31, 2013 and 2012, respectively.  For the three months ended March 31, 2013, approximately $103,000 and approximately $8,000 are included in Selling, General and Administrative expenses and Research and Development expenses, respectively, on the accompanying condensed consolidated statement of operations. For the three months ended March 31, 2012, approximately $54,000 and approximately $6,000 are included in Selling, General and Administrative expenses and Research and Development expenses, respectively, on the accompanying condensed consolidated statement of operations.

There was no tax benefit related to expense recognized in the three months ended March 31, 2013 and 2012, as the Company is in a net operating loss position. As of March 31, 2013, there was approximately $973,000 of total unrecognized compensation cost related to unvested share-based compensation awards granted under the equity compensation plans which will be amortized over the weighted average remaining requisite service period of 2.8 years.  Such amount does not include the effect of future grants of equity compensation, if any.  Of the total $973,000, the Company expects to recognize approximately 30% in the remaining interim periods of 2013, approximately 32% in 2014, approximately 31% in 2015, and approximately 7% in 2016.

For the three months ended March 31, 2013, 1,633,085 warrants were exercised, resulting in proceeds of approximately $30,000 and the issuance of 75,485 shares of the Company’s common stock.

5.   Comprehensive Income (Loss)

Comprehensive income (loss), as defined in ASC 220, is the total of net income (loss) and all other non-owner changes in equity (or other comprehensive income (loss)) such as foreign currency translation adjustments. For the three months ended March 31, 2013 and 2012, the comprehensive loss was approximately $1,242,000 and $513,000, respectively.

 6.   Loss per Common Share

In accordance with ASC 260-10, net loss per common share amounts (“basic EPS”) are 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. However, because their effect is anti-dilutive, the Company has excluded stock options and warrants aggregating 2,294,714 and 14,604,486 shares, respectively, from the computation of diluted EPS for the three months ended March 31, 2013. For the three months ended March 31, 2012, stock options and warrants aggregating 988,164 and 16,309,975 shares, respectively, have been excluded from the computation of diluted EPS.

7.   Recent Accounting Pronouncements

There are no recent accounting pronouncements that are expected to have an effect on the Company’s condensed consolidated interim financial statements.

8.   Inventory, net

Inventory is stated at the lower of cost or market using the first-in first-out method and consists entirely of finished goods. The Company’s inventory as of March 31, 2013 and December 31, 2012 was approximately as follows:

	Unaudited			Audited
	March 31, 2013			December 31, 2012
Total Gross Inventory, Finished Goods	$	465,000		$	581,000
Less: Inventory reserve		(276,000	)		(269,000	)
Total Inventory	$	189,000		$	312,000

9.  Senior Secured Note

On February 4, 2013, the Company issued a Senior Secured Note to Lambda Investors LLC in the principal amount of $1.3 million. The note bears interest at the rate of 12% per annum and matures on August 4, 2013, at which time all principal and accrued interest will be due. However, the Company has agreed to prepay amounts due under the note with the cash proceeds from (a) a rights offering and an offering of a discounted exercise price to public warrantholders, each as further described in the note, (b) any other equity or debt financing, or (c) the issuance or incurrence of any other indebtedness or the sale of any assets outside the ordinary course of business, in each case prior to the maturity date. If the Company does not pay principal and interest under the note when due, the interest rate increases to 16% per annum. The Company may prepay the note without penalty at any time.

The note is secured by a first priority lien on all of the Company’s property, including our intellectual property. As long as indebtedness remains outstanding under the note, the Company will be subject to certain covenants which, among other things, restrict the Company’s ability to merge with another company, sell a material amount of its assets, incur any additional indebtedness, repay any existing indebtedness, or declare or pay any dividends in cash, property or securities.

In connection with the note, the Company has agreed to pay Lambda Investors an 8%, or $104,000, sourcing/transaction fee. In addition, the Company will pay Lambda Investors’ legal fees and other expenses incurred in connection with the note in the amount of $50,000 as well as Lambda Investors’ legal fees and other expenses incurred in connection with the rights offering in the amount of $50,000. Those payments will be paid upon the completion of the rights offering or, if earlier, upon the maturity of the note. The fees have been accrued as of March 31, 2013 and are recorded as selling, general and administrative expenses on the condensed consolidated interim statement of operations for the three months ended March 31, 2013.

As additional consideration, the Company agreed to extend by one year the expiration date of all of Lambda’s outstanding warrants to March 2017.

In addition, the Company agreed to conduct a $3.0 million Rights Offering of common stock. For further discussion of the Rights Offering, see Note 11, Subsequent Events.

10.  Commitments and Contingencies

Manufacturing and Suppliers

The Company has not and does not intend in the near future, to manufacture any of its products and components. With regard to the OLpūr MD190 and MD220, on June 27, 2011, the Company entered into a License Agreement, effective July 1, 2011, with Bellco S.r.l., an Italy-based supplier of hemodialysis and intensive care products, for the manufacturing, marketing and sale of our patented mid-dilution dialysis filters (MD 190, MD 220), referred to herein as the Products. Under the agreement, Nephros granted Bellco a license to manufacture, market and sell the Products under its own name, label and CE mark in Italy, France, Belgium, Spain and Canada on an exclusive basis, and to do the same on a non-exclusive basis in the United Kingdom and Greece and, upon our written approval, other European countries where the Company does not sell the Products as well as non-European countries (referred to as the “Territory”).

In exchange for the rights granted to it under the Bellco License Agreement through December 31, 2014, Bellco agreed to pay Nephros installment payments of €500,000, €750,000, €600,000 on July 1, 2011, January 15, 2012 and January 15, 2013, respectively. Such installment payments, herein referred to as the Installment Payments, are Bellco’s sole financial obligations through December 31, 2014. All payments have been received. Beginning on January 1, 2015 through and including December 31, 2016, Bellco will pay Nephros a royalty based on the number of units of Products sold per year in the Territory as follows: for the first 103,000 units sold, Bellco will pay €4.50 per unit; thereafter, Bellco will pay €4.00 per unit. Bellco must meet minimum sales targets of 15,000 units in each quarter of 2015 and 2016. If Bellco fails to meet a quarterly minimum, the license in Italy, France, Belgium, Spain and Canada will, at our discretion, convert to a non-exclusive one. All sums payable under the agreement will be paid in Euros, as adjusted to account for currency exchange fluctuations between the Euro and the U.S. dollar that occur between July 1, 2011, the effective date of the agreement, and the date of payment.

10.  Commitments and Contingencies (continued)

License and Supply Agreement

On April 23, 2012, the Company entered into a License and Supply Agreement (the “License and Supply Agreement”) with Medica S.p.A. (“Medica”), an Italy-based medical product manufacturing company, for the marketing and sale of certain filtration products based upon Medica’s proprietary Medisulfone ultrafiltration technology in conjunction with the Company’s filtration products (collectively, the “Filtration Products”), and to engage in an exclusive supply arrangement for the Filtration Products. Under the License and Supply Agreement, Medica granted to the Company an exclusive license, with right of sublicense, to market, promote, distribute, offer for sale and sell the Filtration Products worldwide, excluding Italy for the first three years, during the term of the License and Supply Agreement. In addition, the Company granted to Medica an exclusive license under the Company’s intellectual property to make the Filtration Products during the term of the License and Supply Agreement. In exchange for the rights granted, the Company has agreed to make minimum annual aggregate purchases from Medica of €300,000, €500,000 and €750,000 for the years 2012, 2013 and 2014, respectively. For the three months ended March 13, 2013, the Company’s aggregate purchase commitments totaled approximately €81,000. For calendar years thereafter, annual minimum amounts will be mutually agreed upon between Medica and the Company.

As consideration for the license and other rights granted to the Company, the Company is required to pay Medica installment payments of €500,000 and €1,000,000 on April 23, 2012 and January 25, 2013, respectively. The April 23, 2012 payment was made. In the three months ended March 31, 2013, €600,000 was paid to Medica for the payment due January 25, 2013. Both parties agreed that the Company may defer the remaining €400,000 payment to June 2013. As further consideration for the license and other rights granted to the Company, the Company granted Medica options to purchase 300,000 shares of the Company’s common stock. The fair market value of these stock options was approximately $273,000 at the time of their issuance, calculated as described in Note 4, Stock-Based Compensation. The fair market value of the options has been capitalized as a long-term intangible asset along with the total installment payments described. Other long-term assets on the condensed consolidated interim balance sheet as of March 31, 2013 is approximately $2,056,000, net of $195,000 accumulated amortization, and is related to the License and Supply Agreement. The asset is being amortized as an expense over the life of the agreement. Approximately $53,000 has been charged to amortization expense for the three months ended March 31, 2013 on the condensed consolidated interim statement of operations and comprehensive loss. Approximately $155,000 of amortization expense will be recognized in the remainder of the year ended December 31, 2013 and approximately $208,000 will be recognized in the years ended 2014 and 2015, respectively. In addition, for the period beginning April 23, 2014 through December 31, 2022, the Company will pay Medica a royalty rate of 3% of net sales of the Filtration Products sold, subject to reduction as a result of a supply interruption pursuant to the terms of the License and Supply Agreement. The term of the License and Supply Agreement commenced on April 23, 2012 and continues in effect through December 31, 2022, unless earlier terminated by either party in accordance with the terms of the License and Supply Agreement.

11.  Subsequent Events

The Company’s Registration Statement on Form S-1 related to the rights offering was declared effective by the SEC on April 17, 2013.

The rights offering commenced on April 17, 2013 and will expire on May 17, 2013, unless the offering period is extended by the Company in its sole discretion. All of the Company’s stockholders and warrantholders are eligible to participate in the offering on a pro rata basis based upon their proportionate ownership of the company’s common stock on a fully-diluted basis. Pursuant to the rights offering, the Company distributed to holders of its common stock and/or warrants one non-transferable subscription right for each share of common stock, and each share of common stock underlying a warrant, held as of April 4, 2013. Each right entitles the holder to purchase 0.18776 of a share of the Company’s common stock at a subscription price of $0.60 per share. The Company will round up any fractional shares to the nearest whole share.

The rights offering includes an over-subscription privilege which permits each rights holder that exercises its rights in full to purchase additional shares of common stock that remain unsubscribed at the expiration of the rights offering. This over-subscription privilege is subject to the availability and allocation of shares among holders exercising this over-subscription privilege. Assuming the rights offering is fully subscribed, the Company estimates that it will receive gross proceeds of $3 million, less the expenses of the rights offering.

Subject to the satisfaction of certain conditions including compliance with all obligations under the note, security agreement and the other transaction documents relating to the note and no material adverse change having occurred with respect to the business, assets, and financial condition of the Company, Lambda Investors has advised the Company that it intends to exercise its basic subscription privilege in full and to purchase any shares of common stock that are not subscribed for by other stockholders in the rights offering, if any.

On April 17, 2013, the Company also announced that commencing on April 17, 2013 and during the period that the rights offering is open, it has temporarily reduced the exercise price for its warrants issued in March 2011 from $0.40 per share to $0.30 per share. After the expiration of this offering period, the exercise price will revert back to $0.40 per share.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

This discussion should be read in conjunction with our consolidated financial statements included in this Quarterly Report on Form 10-Q and the notes thereto, as well as the other sections of this Quarterly Report on Form 10-Q, including the “Certain Risks and Uncertainties” section hereof, and our Annual Report on Form 10-K for the year ended December 31, 2012, including the “Risk Factors” and “Business” sections thereof.  This discussion contains a number of forward-looking statements, all of which are based on our current expectations and could be affected by the uncertainties and risk factors described in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2012. Our actual results may differ materially.

Financial Operations Overview

Revenue Recognition: Revenue is recognized in accordance with ASC Topic 605. Four basic criteria must be met before revenue can be recognized: (i) persuasive evidence that an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed and determinable; and (iv) collectability is reasonably assured.

Cost of Goods Sold: Cost of goods sold represents the acquisition cost for the products we purchase from our third party manufacturers as well as damaged and obsolete inventory written off.

Research and Development: Research and development expenses consist of costs incurred in identifying, developing and testing product candidates. These expenses consist primarily of salaries and related expenses for personnel, fees of our scientific and engineering consultants and subcontractors and related costs, clinical studies, machine and product parts and software and product testing. We expense research and development costs as incurred.

Selling, General and Administrative: Selling, general and administrative expenses consist primarily of sales and marketing expenses as well as personnel and related costs for general corporate functions, including finance, accounting, legal, human resources, facilities and information systems expense.

Business Overview

Nephros is a commercial stage medical device company that develops and sells high performance liquid purification filters. Our filters, which we call ultrafilters, are primarily used in dialysis centers and healthcare facilities for the production of ultrapure water and bicarbonate. Because our ultrafilters capture contaminants as small as 0.005 microns in size, they eliminate a wide variety of bacteria, viruses, fungi, parasites, and endotoxins harmful to humans.

All of our ultrafilters use proprietary hollow fiber technology. We believe the hollow fiber design allows our ultrafilters to be the only commercially available filters for healthcare applications that optimize the three elements critical to filter performance:

· Filtration - as low as 0.005 microns

· Flow rate - minimal disruption

· Filter life - up to 12 months

By comparison, competitive filters on the market today are typically effective only to the 0.2 micron level and are prone to clog more quickly, thus reducing their useful lives.

We were founded in 1997 by healthcare professionals affiliated with Columbia University Medical Center/New York-Presbyterian Hospital to develop and commercialize an alternative method to hemodialysis (HD). In 2009, we began to extend our filtration technologies to meet the demand for liquid purification in other areas, in particular water purification.

Our Products

Presently, we offer seven types of ultrafilters for sale to customers in four markets:

· Dialysis Centers - Water/Bicarbonate: Treatment of both water and bicarbonate for the production of ultrapure dialysate

· Hospitals and Other Healthcare Facilities: Removal of infectious agents in drinking and bathing water, particularly in high risk patient areas 

· Military: Highly compact, individual water treatment devices used by soldiers to produce safe drinking water in the field

9

· Dialysis Centers - Blood: Clearance of toxins from blood using an alternative method to HD in patients with chronic renal failure

We have designed our ultrafilters as either in-line products, filters that are incorporated into the existing plumbing of healthcare facilities, or point-of-use products, filters that can be easily installed onto a faucet or as a replacement shower head or can be used stand-alone to purify small quantities of water immediately prior to use.

Our Target Markets

Dialysis Centers - Water/Bicarbonate. To perform hemodialysis, all dialysis clinics have dedicated water purification systems to produce pure water and bicarbonate. Water and bicarbonate are essential ingredients for making dialysate, the liquid that removes waste material from the blood. Within the U.S., there are approximately 5,700 clinics with 100,000 dialysis machines providing over 50 million dialysis treatments to 370,000 patients annually.

Medicare is the main payor for dialysis treatment in the U.S. To be eligible for Medicare reimbursement, dialysis centers must meet the minimum standards for water and bicarbonate quality set by the Association for the Advancement of Medical Instrumentation (AAMI), the American National Standards Institute (ANSI) and the International Standards Organization (ISO). We anticipate that the stricter standards approved by these organizations in 2009 will be adopted by Medicare in the near future.

Published studies have shown that the use of ultrapure dialysate can make patients healthier and reduce their dependence on erythropoietin (EPO), an expensive drug used in conjunction with HD. By reducing the level of dialysate contaminants, specifically cytokine-inducing substances that can pass into a patient’s blood stream, cytokine levels within a patient stay low, thus reducing systemic inflammation. When inflammation is low, inflammatory morbidities are reduced and a patient’s responsiveness to EPO is enhanced, consequently the overall need for the drug is reduced.

We believe that our ultrafilters are attractive to dialysis centers because they exceed currently approved and newly proposed standards for water/bicarbonate purity, assist in achieving those standards and help dialysis centers reduce costs associated with the amount of EPO required to treat a patient. Our in-line filters are easily installed into the fluid circuits supplying water and bicarbonate just prior to entering each dialysis machine.

Hospitals and Other Healthcare Facilities. According to the United States Centers for Disease Control and Prevention (CDC), healthcare acquired infections (HAIs) annually account for 1.7 million infections, 99,000 deaths, and $4.5 - $6.5 billion in extra costs in U.S. hospitals. At the root of many HAIs are waterborne pathogens such as Legionella and Pseudomonas which can thrive in aging or complex plumbing systems often found in healthcare facilities. According to the CDC, 23% of Legionella infections originate in healthcare facilities and Pseudomonas infections account for 10% of all water-related HAIs. These pathogens are most harmful to patients in intensive care, neonatal, burn, cancer, and transplant units.

The Affordable Care Act (ACA) which was passed in March 2010 puts in place comprehensive health insurance reforms that aim to lower costs and enhance quality of care. With its implementation, healthcare providers have substantial incentives to deliver better care or be forced to absorb the expenses associated with repeat medical procedures or complications like HAIs. The ACA encompasses HAIs and shifts the costs associated with their treatment back onto the healthcare provider. As a consequence, hospitals and other healthcare facilities are proactively implementing strategies to reduce the potential for HAIs.

Our ultrafilters are designed to reduce the risk of HAIs in the hospital/healthcare setting by treating water just prior to use. Our products can be used for reactive infection control. For example, during acute disease outbreaks (such as Legionnaires’ disease), our ultrafilters have been used at hospitals and other healthcare facilities to quickly and efficiently assist in the control of such outbreaks. Our ultrafilters are also being used as a preventative measure in healthcare facilities, particularly in areas where high risk patients are being treated. Our point-of-use filters can be easily installed onto the end of faucets or as replacement shower heads.

The plastic casing of our hospital ultrafilters contains BACTiglas^TM. BACTiglas^TM releases silver ions at the surface of the plastic casing such that they are imparted to anything that touches it. Silver ions (through chemical bonding with amino acids) result in the killing of the bacteria that remains on the surface of the plastic. This enables our hospital ultrafilters to be bactericidal to any touch contamination or any growth on the surface of the plastic in addition to their water treatment effect.

In March 2012 we filed an application with the General Services Administration (GSA) for listing on a GSA schedule. The GSA is an independent agency of the U.S. Government that establishes long term Government wide contracts (GSA Schedules) that allow Federal employees to acquire products directly from suppliers, like Nephros, at pre-agreed pricing and terms. On March 27, 2013, we received notification from the GSA that our Dual Stage Ultrafilter (“DSU”) and SafeSpout have been added to a GSA Schedule and we can enter our products onto the GSA Advantage!^® website. GSA Advantage!^® is the U.S. Governments premier on-line shopping system. Both the DSU and the SafeSpout are now available through GSA Advantage!^®.

Military. The military is heavily reliant on the use of bottled water to support its soldiers in the field. Bottled water is not always available, is very costly to move, resource intensive, and prone to constant supply disruptions. Soldiers conducting operations in isolated and rugged terrain must be able to use available local water sources when unable to resupply from bulk drinking water sources or bottled water. Therefore, the soldier needs the capability to purify water from indigenous water sources in the absence of available potable water. Soldiers must have the ability to remove microbiological contaminants in the water to Environmental Protection Agency specified levels; thereby reducing the effects of acute debilitating illnesses.

10

We offer our individual water purification device (IWPD), which allows a soldier in the field to derive biologically safe water from any fresh water source. Our IWPD is available in both in-line and point-of-use configurations. Our IWPD is one of the few portable filters that has been validated by the military to meet the NSF Protocol P248 standard. It has also been approved by U.S. Army Public Health Command (USAPHC) and U.S. Army Test and Evaluation Command (ATEC) for deployment. To date, we have received purchase orders for approximately 2,000 IWPDs from individual units of the U.S. armed forces.

In January 2013, the U.S. Army issued a request for proposal (RFP) relating to an IWPD, Nephros submitted its response to this RFP on February 25, 2013. On March 29, 2013, we received notification from the U.S. Army that the Government has completed the initial evaluation of our proposal and found Nephros to be within the competitive range to commence negotiations. We also received a request for 180 of our IWPD to be used as test assets during the Limited User Evaluation phase of the source selection. The U.S. Army may award several, one or no contracts as a result of this solicitation. The maximum quantity of all contracts combined is not to exceed 450,000 units or $45,000,000 over a 3 year period. The RFP evaluation period may take up to 6 months before an award is made, if at all.

Dialysis Centers - Blood. The current standard of care in the U.S. for patients with chronic renal failure is HD, a process in which toxins are cleared via diffusion. Patients typically receive HD treatment at least 3 times weekly for 3-4 hours per treatment. HD is most effective in removing smaller, easily diffusible toxins. For patients with acute renal failure, the current standard of care in the U.S. is hemofiltration (HF), a process where toxins are cleared via convection. HF offers a much better removal of larger sized toxins when compared to HD. However, HF treatment is performed on a daily basis, and typically takes 12-24 hours.

Hemodiafiltration (HDF) is an alternative dialysis modality that combines the benefits of HD and HF into a single therapy by clearing toxins using both diffusion and convection. Though not widely used in the U.S., HDF is much more prevalent in Europe and is performed in approximately 16% of patients. Clinical experience and literature show the following multiple clinical and patient benefits of HDF:

· Enhanced clearance of middle and large molecular weight toxins

· Improved survival - up to a 35% reduction in mortality risk

· Reduction in the occurrence of dialysis-related amyloidosis

· Reduction in inflammation

· Reduction in medication such as EPO and phosphate binders

· Improved patient quality of life

· Reduction in number of hospitalizations and overall length of stay

However, like HF, HDF can be resource intensive and can require a significant amount of time to deliver one course of treatment.

We have developed a modified approach to HDF which is more patient-friendly, less resource-intensive, and can be used in conjunction with current HD machines. We refer to our approach as an online mid-dilution hemodiafiltration (mid-HDF) system and it consists of our OLpūr H2H Module and OLpūr MD 220 Hemodiafilter. On April 30, 2012, we announced that we received clearance from the U.S. Food and Drug Administration to market the OLpūr H2H Module and OLpūr MD 220 Hemodiafilter for use with a UF controlled hemodialysis machine that provides ultrapure dialysate in accordance with current ANSI/AAMI/ISO standards, for the treatment of patients with chronic renal failure in the United States. Like HD, online mid-HDF treatment is given to patients at least 3 times weekly for 3-4 hours per treatment. Our mid-HDF system is the only HDF system of its kind to be cleared by the FDA to date.

We are currently preparing our OLpūr H2H Modules and manufacturing our OLpūr MD220 Hemodiafilters in readiness for market release. We expect to place a mid-HDF system in a U.S. dialysis clinic in Q2. We have not begun to broadly market our mid-HDF system and plan to seek a commercialization partner in the U.S.

Critical Accounting Policies

The discussion and analysis of our consolidated financial condition and results of operations are based upon our condensed consolidated financial statements. These condensed consolidated financial statements have been prepared following the requirements of accounting principles generally accepted in the United States (“GAAP”) and Rule 8-03 of Regulation S-X for interim periods and require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to potential impairment of investments and share-based compensation expense. As these are condensed consolidated financial statements, you should also read expanded information about our critical accounting policies and estimates provided in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” included in our Form 10-K for the year ended December 31, 2012. There have been no material changes to our critical accounting policies and estimates from the information provided in our Form 10-K for the year ended December 31, 2012.

Recently Adopted Accounting Pronouncements

There are no recent accounting pronouncements that are expected to have an effect on the Company’s condensed consolidated interim financial statements set forth in Item 1 of this Quarterly Report on Form 10-Q.

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 quarterly 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, as well as marketing expenses related to product launches.  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.

Three Months Ended March 31, 2013 Compared to the Three Months Ended March 31, 2012

Revenues

Total net revenues for the three months ended March 31, 2013 were approximately $521,000 compared to approximately $533,000 for the three months ended March 31, 2012.  Total net revenues decreased approximately $12,000, or 2% mainly as a result of decreases of approximately $117,000 related to the Office of Naval Research (“ONR”) contract which ended as of March 31, 2012. This was partially offset by a 42% increase of water filter sales which increased from approximately $243,000 in 2012 to $345,000 in 2013 and approximately $1,000 of licensing revenue related to the Bellco license agreement.

Cost of Goods Sold

Cost of goods sold was approximately $196,000 for the three months ended March 31, 2013 compared to approximately $222,000 for the three months ended March 31, 2012. The decrease of approximately $26,000 or 12% during the three months ended March 31, 2013 compared to the same period in 2012 is primarily due to the reduction of related to the ONR contract of approximately $62,000. The ONR contract ended as of March 31, 2012. This was partially offset by increased cost of goods sold of approximately $36,000 related to increased water filter sales for the three months ended March 31, 2013 compared to the same period in 2012.

Research and Development

Research and development expenses were approximately $223,000 and $145,000 respectively, for the three months ended March 31, 2013 and March 31, 2012. This increase of approximately $78,000, or 54%, is primarily due to an increase in research and development personnel related costs of approximately $32,000 and an increase in research and development materials and other project costs of approximately $46,000 during the three months ended March 31, 2013 compared to the same period in 2012. The increase in personnel costs is not due to an increase in headcount but rather due to the ONR contract having ended as of March 31, 2012. Time spent on the ONR contract in 2012 was reclassified to Cost of Goods Sold from Research and Development expenses. Since the contract ceased as of March 31, 2012, all of the personnel costs are included in Research and Development expenses in 2013.

Depreciation and Amortization Expense

Depreciation and amortization expense was approximately $55,000 for the three months ended March 31, 2013 compared to approximately $2,000 for the three months ended March 31, 2012. The increase of approximately $53,000 is due to amortization related to the asset recognized in conjunction with the License and Supply Agreement with Medica S.p.A (“License and Supply Agreement”) which began on April 23, 2012.

Selling, General and Administrative Expenses

Selling, general and administrative expenses were approximately $1,259,000 for the three months ended March 31, 2013 compared to approximately $720,000 for the three months ended March 31, 2012, an increase of approximately $539,000 or 75%. The increase is primarily due to increases in personnel costs of approximately $233,000, approximately $204,000 related to fees incurred as a result of the issuance of a $1.3 million senior secured note (“Senior Secured Note”) to Lambda Investors LLC, an increase in legal fees of approximately $50,000, an increase in travel related expenses of approximately $45,000 and an increase in other expenses of approximately $7,000 during the three months ended March 31, 2013 compared to the same period in 2012.

12

Interest Income

There was no interest income for the three months ended March 31, 2013 compared with $1,000 for the three months ended March 31, 2012.

Interest Expense

Interest expense was approximately $24,000 for the three months ended March 31, 2013 and related primarily to accrued interest recognized as a result of the Senior Secured Note outstanding as of March 31, 2013. We had no interest expense for the three months ended March 31, 2012.

Gain on Sale of Equipment

A gain of approximately $2,000 was recognized for the three months ended March 31, 2013 related to the sale of fully depreciated equipment.

Other Expense

Other expense in the amount of approximately $8,000 for the three months ended March 31, 2013 was due to foreign currency losses on invoices paid to an international suppler. This compared to foreign currency losses arising of $2,000 for the three months ended March 31, 2012.

Liquidity and Capital Resources

At March 31, 2013, we had an accumulated deficit of approximately $98,772,000 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 license revenue. We have financed our operations since inception primarily through the private placements of equity and debt securities, our initial public offering, license revenue and the March 2011 rights offerings and concurrent private placement.

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

· the availability of additional financing, through the April 2013 rights offering or other sales of equity securities or otherwise, on commercially reasonable terms or at all;

· the market acceptance of our products, and our ability to effectively and efficiently produce and market our products;

· 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 water-filtration products;

· to pursue business development opportunities with respect to our chronic renal treatment system; and

· for working capital purposes.

At March 31, 2013, we had cash and cash equivalents totaling approximately $243,000 and tangible assets of approximately $681,000. Tangible assets consist of total assets of approximately $2,737,000, reduced by other intangible assets (related to the Medica License and Supply Agreement) of approximately $2,056,000.

On June 27, 2011, we entered into a License Agreement with Bellco S.r.l., as licensee (“Bellco”), an Italy-based supplier of hemodialysis and intensive care products, for the manufacturing, marketing and sale of Nephros’ patented mid-dilution dialysis filters. This Agreement provides us with payments of €500,000, €750,000, and €600,000 on July 1, 2011, January 15, 2012 and January 15, 2013, respectively. All payments have been received.   Beginning on January 1, 2015 through and including December 31, 2016, Bellco will pay to Nephros a royalty based on the number of units of Products sold in the Territory as follows: for the first 103,000 units sold,  €4.50 per unit; thereafter, €4.00 per unit.  Anticipated payments from this License Agreement will be a positive source of cash flow to our Company.

Our cash flow currently is not, and historically has not been, sufficient to meet our obligations and commitments. We must seek and obtain additional financing to fund our operations. If we cannot raise sufficient capital, we will be forced to curtail our planned activities and operations or cease operations entirely. There can be no assurance that we will be able to raise sufficient capital on a timely basis or on satisfactory terms or at all.

13

Net cash used in operating activities was approximately $1,133,000 for the three months ended March 31, 2013 (“2013 period”) compared to net cash provided by operating activities of approximately $425,000 for the three months ended March 31, 2012 (“2012 period”). The most significant items contributing to this increase of approximately $1,558,000 in cash used by operating activities during the three months ended March 31, 2013 compared to the three months ended March 31, 2012 are highlighted below:

· during the 2013 period, our net loss increased by approximately $685,000;

· during the 2012 period, net cash provided by operating activities increased as a result of other assets decreasing  by approximately $778,000 for which there was no comparable activity during the 2013 period;

· during the 2013 period, our license and supply fee payable decreased by approximately $815,000;

· our accounts payable and accrued expenses decreased  by approximately $31,000 in aggregate in the 2013 period compared to an increase of approximately $162,000 in the aggregate in the 2012 period;

Offsetting the above changes are the following items:

· our accounts receivable decreased by approximately $797,000 during the 2013 period compared to a decrease  of approximately $162,000 during the 2012 period;

· our inventory decreased by approximately $117,000 during the 2013 period compared to a decrease of approximately $7,000 during the 2012 period;

· amortization expense related to asset associated with the License and Supply Agreement was approximately $53,000 for the 2013 period; 

· noncash interest expense was approximately $24,000 for the 2013 period;

· during the 2013 period, our stock-based compensation expense increased by approximately $51,000;

· our prepaid expenses and other current assets decreased  by approximately $13,000 in the 2013 period compared to an increase of approximately $16,000 in the 2012 period.

Cash provided by investing activities of approximately $2,000 for the three months ended March 31, 2013 resulted from proceeds from the sale of fully depreciated equipment.

Net cash provided by financing activities for the three months ended March 31, 2013 of $1,330,000 resulted from gross proceeds of $1,300,000 related to the issuance of a Senior Secured Note and approximately $30,000 of proceeds resulting from the exercise of warrants.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Not Required.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain a system of disclosure controls and procedures, as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which is designed to provide reasonable assurance that information required to be disclosed in our reports filed pursuant to the Exchange Act is accumulated and communicated to management in a timely manner. Management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives. Because there are inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud have been or will be detected. At the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, regarding the effectiveness of  our disclosure controls and procedures pursuant to Securities and 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 effective.

Changes in Internal Control Over Financial Reporting

Our management, with the participation of the Chief Executive Officer and Chief Financial Officer, has concluded that there were no changes in our internal control over financial reporting, that occurred during the quarter ended March 31, 2013, 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.

Stock-Based Compensation

Stock-Based Compensation [Abstract]

Stock-Based Compensation

4.  Stock-Based Compensation

The Company accounts for stock option grants to employees and non-employee directors under the provisions of ASC 718, Stock Compensation.  ASC 718 requires the recognition of the fair value of stock-based compensation in the statement of operations.  In addition, the Company accounts for stock option grants to consultants under the provisions of ASC 505-50, Equity-Based Payments to Non-Employees, and as such, these stock options are revalued at each reporting period through the vesting period.

The fair value of stock option awards is estimated using a Black-Scholes option pricing model.  The fair value of stock-based awards is amortized over the vesting period of the award using the straight-line method.     

There were no stock options granted by the Company during the three months ended March 31, 2013 to employees, non-employee directors or consultants.   

Stock-based compensation expense was approximately $111,000 and $60,000 for the three months ended March 31, 2013 and 2012, respectively.  For the three months ended March 31, 2013, approximately $103,000 and approximately $8,000 are included in Selling, General and Administrative expenses and Research and Development expenses, respectively, on the accompanying condensed consolidated statement of operations. For the three months ended March 31, 2012, approximately $54,000 and approximately $6,000 are included in Selling, General and Administrative expenses and Research and Development expenses, respectively, on the accompanying condensed consolidated statement of operations.

There was no tax benefit related to expense recognized in the three months ended March 31, 2013 and 2012, as the Company is in a net operating loss position. As of March 31, 2013, there was approximately $973,000 of total unrecognized compensation cost related to unvested share-based compensation awards granted under the equity compensation plans which will be amortized over the weighted average remaining requisite service period of 2.8 years.  Such amount does not include the effect of future grants of equity compensation, if any.  Of the total $973,000, the Company expects to recognize approximately 30% in the remaining interim periods of 2013, approximately 32% in 2014, approximately 31% in 2015, and approximately 7% in 2016.

For the three months ended March 31, 2013, 1,633,085 warrants were exercised, resulting in proceeds of approximately $30,000 and the issuance of 75,485 shares of the Company's common stock.

Revenue Recognition [Abstract]

Revenue Recognition

3.  Revenue Recognition

Revenue is recognized in accordance with Accounting Standards Codification ("ASC") Topic 605. Four basic criteria must be met before revenue can be recognized: (i) persuasive evidence that an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed or determinable; and (iv) collectability is reasonably assured.

The Company recognizes revenue related to product sales when delivery is confirmed by its external logistics provider and the other criteria of ASC Topic 605 are met. Product revenue is recorded net of returns and allowances. All costs and duties relating to delivery are absorbed by Nephros. Shipments for all products are currently received directly by the Company's customers.

Deferred revenue on the accompanying March 31, 2013 condensed consolidated balance sheet is approximately $1,239,000 and is related to the License Agreement with Bellco which is being deferred over the remainder of the expected obligation period. The Company has recognized approximately $1,220,000 of revenue related to this license agreement to date and approximately $175,000 for the three months ended March 31, 2013..

Basis Of Presentation And Going Concern [Abstract]

Basis Of Presentation And Going Concern

1.  Basis of Presentation and Going Concern

Interim Financial Information

The accompanying unaudited condensed consolidated interim financial statements of Nephros, Inc. and its wholly owned subsidiary, Nephros International Limited (collectively, the "Company" or "Nephros") should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's 2012 Annual Report on Form 10-K filed with the Securities and Exchange Commission (the "SEC") on March 4, 2013. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 and Article 10 of Regulation S-X. Accordingly, since they are interim statements, the accompanying condensed consolidated financial statements do not include all of the information and notes required by GAAP for a complete financial statement presentation. The condensed consolidated balance sheet as of December 31, 2012 was derived from the Company's audited consolidated financial statements but does not include all disclosures required by GAAP. In the opinion of management, the interim condensed consolidated financial statements reflect all adjustments consisting of normal, recurring adjustments that are necessary for a fair presentation of the financial position, results of operations and cash flows for the condensed consolidated interim periods presented. Interim results are not necessarily indicative of results for a full year. Certain reclassifications were made to the prior year's amounts to conform to the 2013 presentation. All significant intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amount of revenues and expenses, during the reporting period. Actual results could differ materially 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 Company's condensed consolidated interim financial statements do not include any adjustments that might result from the outcome of this uncertainty.

The Company has incurred significant losses in operations in each quarter since inception. For the three months ended March 31, 2013 and 2012, the Company has incurred net losses of $1,242,000 and $557,000, respectively. 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, its results of operations and financial condition will be materially and adversely affected.

On June 27, 2011, the Company entered into a License Agreement,  effective July 1, 2011, with Bellco S.r.l., as licensee ("Bellco"), an Italy-based supplier of hemodialysis and intensive care products, for the manufacturing, marketing and sale of Nephros' patented mid-dilution dialysis filters.  This Agreement provides the Company with payments of €500,000, €750,000, and €600,000 on July 1, 2011, January 15, 2012 and January 15, 2013, respectively.  All payments have been received.  Beginning on January 1, 2015 through and including December 31, 2016, Bellco will pay to Nephros a royalty based on the number of units of products sold per year in the territory as follows: for the first 103,000 units sold,  €4.50 per unit; thereafter, €4.00 per unit.   Anticipated payments from this License Agreement will be a positive source of cash flow to the Company.

On February 4, 2013, the Company issued a senior secured note ("Senior Secured Note") to Lambda Investors LLC in the principal amount of $1.3 million.   In addition, on March 4, 2013, the Company filed an S-1 in connection with a $3.0 million rights offering ("Rights Offering") of common stock.  For a more detailed discussion of the terms of the Senior Secured Note and the Rights Offering, see Note 9, Senior Secured Note and Note 11, Subsequent Events, respectively.

There can be no assurance that the Company's future cash flow will be sufficient to meet its obligations and commitments. If the Company is unable to generate sufficient cash flow from operations in the future to service its commitments the Company will be required to adopt alternatives, such as seeking to raise debt or equity capital, curtailing its planned activities or ceasing its 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 the Company to continue to satisfy its capital requirements.

Loss Per Common Share [Abstract]

Loss Per Common Share

6.   Loss per Common Share

In accordance with ASC 260-10, net loss per common share amounts ("basic EPS") are 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. However, because their effect is anti-dilutive, the Company has excluded stock options and warrants aggregating 2,294,714 and 14,604,486 shares, respectively, from the computation of diluted EPS for the three months ended March 31, 2013. For the three months ended March 31, 2012, stock options and warrants aggregating 988,164 and 16,309,975 shares, respectively, have been excluded from the computation of diluted EPS.

Commitments And Contingencies

10.  Commitments and Contingencies

Manufacturing and Suppliers

The Company has not and does not intend in the near future, to manufacture any of its products and components. With regard to the OLpr MD190 and MD220, on June 27, 2011, the Company entered into a License Agreement, effective July 1, 2011, with Bellco S.r.l., an Italy-based supplier of hemodialysis and intensive care products, for the manufacturing, marketing and sale of our patented mid-dilution dialysis filters (MD 190, MD 220), referred to herein as the Products. Under the agreement, Nephros granted Bellco a license to manufacture, market and sell the Products under its own name, label and CE mark in Italy, France, Belgium, Spain and Canada on an exclusive basis, and to do the same on a non-exclusive basis in the United Kingdom and Greece and, upon our written approval, other European countries where the Company does not sell the Products as well as non-European countries (referred to as the "Territory").

In exchange for the rights granted to it under the Bellco License Agreement through December 31, 2014, Bellco agreed to pay Nephros installment payments of €500,000, €750,000, €600,000 on July 1, 2011, January 15, 2012 and January 15, 2013, respectively. Such installment payments, herein referred to as the Installment Payments, are Bellco's sole financial obligations through December

31, 2014. All payments have been received. Beginning on January 1, 2015 through and including December 31, 2016, Bellco will pay Nephros a royalty based on the number of units of Products sold per year in the Territory as follows: for the first 103,000 units sold, Bellco will pay €4.50 per unit; thereafter, Bellco will pay €4.00 per unit. Bellco must meet minimum sales targets of 15,000 units in each quarter of 2015 and 2016. If Bellco fails to meet a quarterly minimum, the license in Italy, France, Belgium, Spain and Canada will, at our discretion, convert to a non-exclusive one. All sums payable under the agreement will be paid in Euros, as adjusted to account for currency exchange fluctuations between the Euro and the U.S. dollar that occur between July 1, 2011, the effective date of the agreement, and the date of payment.

License and Supply Agreement

On April 23, 2012, the Company entered into a License and Supply Agreement (the "License and Supply Agreement") with Medica S.p.A. ("Medica"), an Italy-based medical product manufacturing company, for the marketing and sale of certain filtration products based upon Medica's proprietary Medisulfone ultrafiltration technology in conjunction with the Company's filtration products (collectively, the "Filtration Products"), and to engage in an exclusive supply arrangement for the Filtration Products. Under the License and Supply Agreement, Medica granted to the Company an exclusive license, with right of sublicense, to market, promote, distribute, offer for sale and sell the Filtration Products worldwide, excluding Italy for the first three years, during the term of the License and Supply Agreement. In addition, the Company granted to Medica an exclusive license under the Company's intellectual property to make the Filtration Products during the term of the License and Supply Agreement. In exchange for the rights granted, the Company has agreed to make minimum annual aggregate purchases from Medica of €300,000, €500,000 and €750,000 for the years 2012, 2013 and 2014, respectively. For the three months ended March 13, 2013, the Company's aggregate purchase commitments totaled approximately €81,000. For calendar years thereafter, annual minimum amounts will be mutually agreed upon between Medica and the Company.

As consideration for the license and other rights granted to the Company, the Company is required to pay Medica installment payments of €500,000 and €1,000,000 on April 23, 2012 and January 25, 2013, respectively. The April 23, 2012 payment was made. In the three months ended March 31, 2013, €600,000 was paid to Medica for the payment due January 25, 2013. Both parties agreed that the Company may defer the remaining €400,000 payment to June 2013. As further consideration for the license and other rights granted to the Company, the Company granted Medica options to purchase 300,000 shares of the Company's common stock. The fair market value of these stock options was approximately $273,000 at the time of their issuance, calculated as described in Note 4, Stock-Based Compensation. The fair market value of the options has been capitalized as a long-term intangible asset along with the total installment payments described. Other long-term assets on the condensed consolidated interim balance sheet as of March 31, 2013 is approximately $2,056,000, net of $195,000 accumulated amortization, and is related to the License and Supply Agreement. The asset is being amortized as an expense over the life of the agreement. Approximately $53,000 has been charged to amortization expense for the three months ended March 31, 2013 on the condensed consolidated interim statement of operations and comprehensive loss. Approximately $155,000 of amortization expense will be recognized in the remainder of the year ended December 31, 2013 and approximately $208,000 will be recognized in the years ended 2014 and 2015, respectively. In addition, for the period beginning April 23, 2014 through December 31, 2022, the Company will pay Medica a royalty rate of 3% of net sales of the Filtration Products sold, subject to reduction as a result of a supply interruption pursuant to the terms of the License and Supply Agreement. The term of the License and Supply Agreement commenced on April 23, 2012 and continues in effect through December 31, 2022, unless earlier terminated by either party in accordance with the terms of the License and Supply Agreement.

Senior Secured Note

9.  Senior Secured Note

On February 4, 2013, the Company issued a Senior Secured Note to Lambda Investors LLC in the principal amount of $1.3 million. The note bears interest at the rate of 12% per annum and matures on August 4, 2013, at which time all principal and accrued interest will be due. However, the Company has agreed to prepay amounts due under the note with the cash proceeds from (a) a rights offering and an offering of a discounted exercise price to public warrantholders, each as further described in the note, (b) any other equity or debt financing, or (c) the issuance or incurrence of any other indebtedness or the sale of any assets outside the ordinary course of business, in each case prior to the maturity date. If the Company does not pay principal and interest under the note when due, the interest rate increases to 16% per annum. The Company may prepay the note without penalty at any time.

The note is secured by a first priority lien on all of the Company's property, including our intellectual property. As long as indebtedness remains outstanding under the note, the Company will be subject to certain covenants which, among other things, restrict the Company's ability to merge with another company, sell a material amount of its assets, incur any additional indebtedness, repay any existing indebtedness, or declare or pay any dividends in cash, property or securities.

In connection with the note, the Company has agreed to pay Lambda Investors an 8%, or $104,000, sourcing/transaction fee. In addition, the Company will pay Lambda Investors' legal fees and other expenses incurred in connection with the note in the amount of $50,000 as well as Lambda Investors' legal fees and other expenses incurred in connection with the rights offering in the amount of $50,000. Those payments will be paid upon the completion of the rights offering or, if earlier, upon the maturity of the note.   The fees have been accrued as of March 31, 2013 and are recorded as selling, general and administrative expenses on the condensed consolidated interim statement of operations for the three months ended March 31, 2013.

As additional consideration, the Company agreed to extend by one year the expiration date of all of Lambda's outstanding warrants to March 2017.

In addition, the Company agreed to conduct a $3.0 million Rights Offering of common stock. For further discussion of the Rights Offering, see Note 11, Subsequent Events.

Subsequent Events

11.  Subsequent Events

The Company's Registration Statement on Form S-1 related to the rights offering was declared effective by the SEC on April 17, 2013.

The rights offering commenced on April 17, 2013 and will expire on May 17, 2013, unless the offering period is extended by the Company in its sole discretion. All of the Company's stockholders and warrantholders are eligible to participate in the offering on a pro rata basis based upon their proportionate ownership of the company's common stock on a fully-diluted basis. Pursuant to the rights offering, the Company distributed to holders of its common stock and/or warrants one non-transferable subscription right for each share of common stock, and each share of common stock underlying a warrant, held as of April 4, 2013. Each right entitles the holder to purchase 0.18776 of a share of the Company's common stock at a subscription price of $0.60 per share. The Company will round up any fractional shares to the nearest whole share.

The rights offering includes an over-subscription privilege which permits each rights holder that exercises its rights in full to purchase additional shares of common stock that remain unsubscribed at the expiration of the rights offering. This over-subscription privilege is subject to the availability and allocation of shares among holders exercising this over-subscription privilege. Assuming the rights offering is fully subscribed, the Company estimates that it will receive gross proceeds of $3 million, less the expenses of the rights offering.  

Subject to the satisfaction of certain conditions including compliance with all obligations under the note, security agreement and the other transaction documents relating to the note and no material adverse change having occurred with respect to the business, assets, and financial condition of the Company, Lambda Investors has advised the Company that it intends to exercise its basic subscription privilege in full and to purchase any shares of common stock that are not subscribed for by other stockholders in the rights offering, if any.

On April 17, 2013, the Company also announced that commencing on April 17, 2013 and during the period that the rights offering is open, it has temporarily reduced the exercise price for its warrants issued in March 2011 from $0.40 per share to $0.30 per share. After the expiration of this offering period, the exercise price will revert back to $0.40 per share.
