                                SUPPLY AGREEMENT
                                ----------------

NEPHROS, Inc., a company organized and existing under the laws of the State of
Delaware, having offices at 3960 Broadway, New York, NY 10032, USA and at 1st
Floor, Suite 5, The Avenue, Beacon Court, Sandyford, Dublin 18, Ireland
(hereinafter referred to as "NEPHROS")

and

Membrana GmbH, a company organized and existing under the laws of Germany having
offices at Oehder Str. 28, D-42289 Wuppertal, Germany (hereinafter referred to
as "Membrana")

WHEREAS, Membrana is engaged, inter alia, in the manufacture and sale of
membranes for medical applications, in particular capillary membranes for
hemodialysis, and is interested in selling such membranes to NEPHROS;

WHEREAS, NEPHROS is a medical products company and is engaged, inter alia, in
the hemodialysis business and intends to manufacture
hemodialyzers/hemodiafilters with capillary membranes and, therefore, is
interested in purchasing capillary membranes from Membrana for incorporation
into such dialyzers.

NOW, THEREFORE, the parties hereto hereby agree to the following:

Article 1:  Scope of the Agreement
----------------------------------

This Agreement shall govern all deliveries from Membrana to NEPHROS of all blood
contacting capillary membrane types for dialysis that Membrana can, during the
term of this Agreement make, including, without limitation DIAPES HF800* or
DIAPES HF800XP capillary membranes as specified in Sheet no. 079/0107/000
attached hereto as Annex I (hereinafter referred to as "DIAPES") and the DIAPES
Capillary Membrane Primary Bundles as specified in Sheet no. 079/0000/000
attached hereto as Annex II and set forth below ("Primary Bundles"). (The use of
marketing or labelling materials containing the DIAPES(R) name by Nephros is not
allowed in Japan)

Article 2:  Specification of Primary Bundles
--------------------------------------------

Membrana shall produce Primary Bundles for NEPHROS from DIAPES according to the
specifications listed below:

                                      * * *

The parties may agree in writing to modify the above specifications and/or add
additional specifications, according to NEPHROS's needs and Membrana's
capabilities. In case of a

<PAGE>
                                       2

switch to a new specification, unless otherwise agreed to in writing by
Membrana, NEPHROS shall purchase all bundles with the former specification, if
any, which NEPHROS had ordered and, at the time of the switch, are still in
stock at Membrana.

If dialysis membrane types other than, or in addition to, DIAPES HF800* or
DIAPES HF800XP will be supplied by Membrana to NEPHROS then a signed supplement
will be added to this Agreement before the first shipment of such membranes (any
such membranes, together with DIAPES HF800* and Primary Bundles are referred to
herein collectively as "Product").

Article 3: Prices
-----------------

3.1 The prices for Products containing DIAPES shall be as follows:

     The parties agree on the following volume-discounted price schedule for the
     purchase of quantities of Product per calendar year. If any incomplete
     calendar year constitutes a portion of the term (any "Incomplete Year") of
     this Agreement, then, for such Incomplete Year, each of the volume
     thresholds set forth below shall be prorated by multiplying it by a
     fraction, the numerator of which is the number of days included in such
     Incomplete Year, and the denominator of which is 365.

           --------------------------------   ---------------------------
            Annual Volume, (Calendar Year)           Average Price
               Km of membrane (millions)               [Euro/km]
           --------------------------------   ---------------------------

                         * * *                           * * *

     For purposes of calculating prices under this table "volume" will be
     calculated as the sum of kilometres of DIAPES ordered by NEPHROS from
     Membrana through purchase orders issued for delivery during the calendar
     year indicated by the purchase order due date. Each Product delivery will
     be included in the "volume" quantity for one calendar year only. Any
     quantities of Product not delivered in the calendar year indicated by the
     purchase order due date will be deemed delivered on the due date solely for
     purposes of calculating annual volume, and shall be delivered as soon as
     possible in the next calendar year, using the original purchase order
     number.

     The final price for annual volumes that fall between these listed values is
     calculated via linear interpolation of the average prices of the
     immediately lower and higher price levels, rounding volumes to the closest
     1,000 kilometres. The resulting price will be rounded to two decimal places
     (i.e., hundredths of Euro).

     Example:
     annual volume = * * *
     actual price = * * *

     At the conclusion of the calendar year, when all purchase orders have been
     placed, the cumulative annual volume will be determined. If NEPHROS's total
     kilometres of DIAPES purchased for the year exceed the amount used to set
     the invoice price for that year, then Membrana shall pay NEPHROS a refund
     so that NEPHROS's total purchase expenditure is made equal to the
     expenditure that would have occurred if the price for the actual volume had
     been invoiced all year. Such payment shall be made by January 31 of the
     following year. Conversely, if NEPHROS's total kilometres of membrane
     purchased are less than the quantity used to set the invoice price, then
     NEPHROS shall pay Membrana a refund so that NEPHROS's total purchase
     expenditure is made equal to the expenditure that would have occurred if
     the price for

<PAGE>
                                       3

     the actual volume had been invoiced all year. Such payment shall be made by
     January 31 of the following year.
             --

3.2 Each year in * * * NEPHROS and Membrana shall reach an agreement on invoice
price for the following year. Such invoice price shall be set according to the
pricing table set forth above in paragraph 3.1, and the volume reasonably and
jointly expected for the following year.

The prices have to be understood as ex works Wuppertal, packing included.

3.3 If NEPHROS exercises the * * *, the form of which is attached hereto as
Annex III, then the prices and price adjustment provisions set forth in this
Article 3 shall only apply to purchases in calendar year 2004 to the extent that
they yield a price per kilometre that is less than * * *.

3.4 Each month NEPHROS shall provide Membrana with a non-binding forecast
indicating its expected requirements of Products for the three months following
the month for which orders have been placed.

3.5 The delivered volume per bundle type may exceed or fall below the
ordered/confirmed amount by * * *.

Article 4: Payment and Delivery Terms
-------------------------------------

4.1  NEPHROS shall send the purchase order at least * * * weeks before shipment
     date, indicating the membrane type, bundle specification, number of
     bundles, and the requested shipping date.

     Membrana will send NEPHROS an order confirmation indicating the details of
     the relevant order and providing a definite date of shipment. Any
     deviations from this confirmation will be communicated to NEPHROS as soon
     as they become known.

4.2  Membrana will invoice NEPHROS at time of shipment, consistent with ex-works
     Wuppertal terms.

4.3  NEPHROS shall effect the payment of the purchase price in Euro by * * *,
     net. Payment shall be made by wire transfer to Membrana's account * * *, or
     as otherwise specified by Membrana from time to time.

Article 5: Quality Data & Technical & Scientific Support
-------------------------------------------------------

With each shipment, Membrana shall provide to both NEPHROS and the "ship-to"
location the `QC Data List' and the `Attachment to MQ-Specification' as given in
ANNEX IV. At NEPHROS's request, Membrana shall provide NEPHROS with technical
and scientific information about each Product, including such information
regarding the membrane types used.

part, for any reason or purpose whatsoever except if such Receiving Party is
required by a court of competent jurisdiction to so disclose after notice has
been given to the Disclosing Party and the Disclosing Party has had an
opportunity to oppose such disclosure or seek a protective order to the extent
practicable. Notwithstanding the foregoing, "Confidential Information" shall not

public other than as a result of the breach by the Receiving Party or any
affiliate of the Receiving Party of an obligation of confidentiality to the
Disclosing Party, (2) was known by the Receiving Party (as evidenced by written
records) prior to its receipt by the Receiving Party from the Disclosing Party,
(3) was disclosed to the Receiving Party by a third party under no obligation of
confidence, or (4) was developed by the Receiving Party independently of any
disclosure made by the Disclosing Party to the Receiving Party, provided, that
the Receiving Party shall have the burden of showing that such information was
developed independently of any disclosure by the Disclosing Party.

                   General Conditions of Sale of Membrana GmbH

                 I. Exclusive validity of our conditions of sale

All of our quotations and tenders are based on our General Conditions of Sale.
We accept purchase orders exclusively on these terms. General terms and
conditions of the purchaser or agreements deviating from our Commercial Code
shall be binding on us only if we expressly recognise them in writing. With the
placing of an order or the acceptance of work of services the purchaser
recognises the validity of our General Terms and Conditions not only for the
business transaction in question, but also for all future business transactions.

                             II. Area of application

Our General Terms and Conditions shall apply only to legal transactions with
companies in the sense of the German Civil Code.

                                  III. Delivery

1.   As soon as the goods leave our works or our warehouse or are made available
     to the Buyer ready for shipping in a manner establishing default in
     acceptance, all transport risks shall pass to the Buyer.

2.   Periods and deadlines agreed upon for our services and work shall only be
     deemed to be binding, if they are expressly designated as such by us. A
     delivery period or a delivery date shall be deemed to have been adhered to,
     if the goods have left our works or our sales warehouse by the expiry of
     the period.

3.   Force Majeure and other obstructions which are beyond our control such as
     war, mobilisation, fire, strike and lockout and suchlike shall exempt us,
     for the duration of such disturbance and its consequences, from the
     obligation to deliver. Should such circumstances occur, after we have
     defaulted, the consequences of default shall remain excluded for the
     duration of their effectiveness. If the delivery period agreed upon is
     exceeded by more than two months, the Buyer and the Seller shall be
     entitled to cancel the part of the contract not performed.

<PAGE>

4.   The Buyer must, if the delivery period is exceeded, set a reasonable
     extension of the period in writing. If we have not performed the work or
     service within this additional period, the Buyer shall be entitled to
     cancel the contract.

5.   From the exceeding of a period for performance or a performance date or
     from performance default the Buyer shall not be entitled to derive any
     claims for damages against us, unless the exceeding of the period or
     deadline is due to wilful intent or gross negligence on the part of one of
     our statutory representative or of one of our vicarious agents.

6.   We shall be entitled to effect part deliveries and to invoice each part
     delivery in itself, as far as a part delivery is tolerable for the Buyer.
     The re-sale of the goods delivered using decorative and packaging material
     owned by us shall require our prior written consent.

7.   Seller may deliver against any order an excess or deficiency of up to 10 %
     of the quantity ordered. The quantity actually delivered will be invoiced.

                                   IV. Payment

1.   Besides the prices agreed, the Buyer must pay the statutory value-added or
     turnover tax at the currently applicable rate.

2.   Retention of due payments or offsetting shall be possible only on the basis
     of claims of the purchaser which have been the subject of non-appealable
     court decisions or have been recognised by us in writing.

3.   All costs arising in connection with the contract in the country of the
     Buyer including fees and taxes which were not known at the time of the
     conclusion of the contract shall be borne by the Buyer.

4.   If, after the conclusion of the contract, circumstances come to our
     knowledge which appear to make the credit worthiness of the purchaser
     doubtful, we can, at our discretion, demand cash in advance or provision of
     securities.

5.   In case of late payment by Buyer, Buyer shall, without prejudice to any
     other right of Seller, be liable to pay interest at a yearly rate of 8 % in
     excess of the basic interest rate (Euribor).

<PAGE>

                              V. Retention of title

1.   The goods supplied by us shall remain our property up to the complete
     settlement of all of our receivables from the reciprocal business
     relationship including any possible current account balance. The goods may
     not be pledged to others or transferred as security.

2.   Should we as a result of a combination of the goods supplied by us with the
     goods of the purchaser not acquire co-ownership, but lose our property, the
     ownership or co-ownership of the Buyer of the new item shall immediately
     pass to us upon its creation. All expectant rights which could lead to such
     an acquisition of ownership or co-ownership by the Buyer, are now already
     assigned to us by the latter. Any possible transfer necessary by us for the
     acquisition of the ownership or co-ownership shall be replaced by the
     agreement that the party ordering a goods preserves the item for us like a
     borrower, or, if the party ordering a good does not own the item, by the
     assignment of the entitlement to surrender against the owner to us already
     agreed hereby. The ownership or co-ownership arising for us is to be
     treated legally like the original goods. Otherwise the goods supplied by us
     and subject to retention of title are also to be treated with care.

3.   If the Buyer, despite default, does not pay or if the Buyer threatens to
     become insolvent, the Buyer must, at our request, surrender the goods
     subject to retention of title for our free disposal. The taking-back of
     goods subject to retention of title does not constitute any cancellation of
     the contract.

4.   All receivables of the Buyer from re-sale of goods of which we have
     ownership or co-ownership (goods subject to retention of title) shall
     already pass to us upon the conclusion of the transaction of sale. This
     shall apply whether the goods are sold to one or to several customers. The
     purchaser must collect the receivables assigned. We can revoke this
     authority, if the purchaser does not punctually meet one of his obligations
     towards us or if circumstances come to our knowledge which make our rights
     appear threatened.

5.   We undertake, at the request of the Buyer, to release the securities (goods
     and accounts receivable) to which we are entitled according to the above
     rules at our discretion, if their value exceeds the claims to be secured by
     more than 20 %. For the valuation of the security their realisable value
     (securing value) is decisive.

6.   If our retention of title loses its validity in the case of supplies abroad
     or for other reasons, the purchaser shall be obliged to grant to us without
     delay security for the items supplied or

<PAGE>

     any other security for our accounts receivable which will be effective
     according to the law applicable in each case and come as close as possible
     to the retention of title according to German law.

7.   The Buyer shall be obliged to insure the goods subject to retention of
     title with the due care and diligence of a prudent businessman and on
     request to provide evidence to the effect that this insurance has been
     taken out. The Buyer already now assigns to us his claims under this
     insurance by way of security.

                                  VI. INCOTERMS

The usual commercial terms such as FOB and CIF shall apply in accordance with
the INCOTERMS of the International Chamber of Commerce in the version as of the
conclusion of the contract.

                         VII. Claims concerning defects

1.   Notices of defects must be sent in writing at the latest within 30 days of
     receipt of the goods - in the case of hidden defects without delay after
     their discovery - stating the invoice and packaging unit. Deviations with
     regard to the raw or colour shade of the goods supplied shall not be deemed
     to be defects, unless they lead to a considerable deterioration in the
     usability of the products made therefrom.

2.   In the case of notices of defects sent in good time and justifiably we
     shall, at our discretion, have the right to reduce the purchase price by a
     reasonable amount or to supply a replacement. In the event of a failed
     delivery of replacement the purchaser shall have the choice between repeat
     delivery of a replacement, reasonable reduction of the price and returning
     of the goods after the refunding of the purchase price. Defects in one part
     of our performance shall not entitle the Buyer to complain about the
     performance as a whole.

3.   If the Buyer wishes to further process the goods despite identifiable
     defects, he shall give us an opportunity to make comments in good time
     prior to this.

4.   Claims of the purchaser based on defects shall be subject to the statute of
     limitations 12 months after the delivery of the goods.

5.   Our warranties shall expire, if the goods are modified by others, moreover,
     our warranty shall expire, if the Buyer does not follow our instructions
     for use.

1.   For consequences

     a)   of errors which occur during contract negotiations, in particular for
          the consequences of inadequate or incorrect advice given to the Buyer,

     b)   the violation of non-essential contractual duties (subsidiary duties),
          for example a consulting or protection obligation,

     c)   an unlawful act, unless it consists of injury for life and limb or the
          impairing of the health of the Buyer, we shall only accept liability
          if these consequences are due to wilful intent or gross negligence of
          one of our statutory representatives or one of our vicarious agents.

2.   Should the Buyer suffer disadvantages as a result of the fact that we
     violate non-essential contractual obligations (subsidiary obligations), for
     example a consulting or protection obligation, we shall likewise only
     accept liability if these consequences are due to wilful intent or gross
     negligence of one of our statutory representatives or one of our vicarious
     agents.

3.   For consequences, as long as they do not consist of injury of life and limb
     or the impairing of the health of the Buyer, or unlawful acts which one of
     our statutory representatives or one of our vicarious agents commit, we
     shall only accept liability if these consequences were brought about by
     wilful intent or gross negligence.

4.   Where Seller gives technical advice to Buyer with respect to the processing
     or treatment of the goods, it is agreed that such advice is given without
     any liability on Seller's part.

                       IX. Make-up and packaging material

If the Buyer does not return decorative and packaging material which remains our
property within a time limit to be determined by us on the terms and conditions
laid down and in a state capable of being used we shall be entitled to invoice
the Buyer for the replacement price and to demand immediate payment for it. If
the Buyer provides evidence of damage considerably below the replacement price,
only this is to be refunded.

     Convention of the United Nations of 11.04.1980 concerning contracts on
     international purchase of goods shall be excluded.

     gap emerge in this contract, the effectiveness of the remaining provisions
     shall not be affected by this.

4.   In place of the ineffective provisions or in order to fill the gap a

     The term of your employment will commence on July 12, 2004 and will end on
July 31, 2006, or such later date to which the term may be extended by joint
agreement between you and Nephros.

     Nephros may terminate your employment for Cause (as defined below), in
which case the provisions of paragraph (a) below shall apply. Nephros may also
terminate your employment in the event of your Disability (as defined below), in
which case the provisions of paragraph (b) below shall apply. Nephros may also
terminate your employment for any other reason by written notice to you, in
which case the provisions of paragraph (c) below shall apply. If your employment
is terminated by reason of your death, retirement or voluntary resignation, then
the provisions of paragraph (a) below shall apply. Nephros may terminate your
employment at the end of the term hereof by not jointly agreeing with you to
extend the term, in which case paragraph (d) below shall apply.

          (a)  In the event that your employment hereunder is terminated during
     the term (x) by Nephros for Cause (as defined below), (y) by reason of your
     death, or (z) by reason of your voluntary resignation or retirement, then
     Nephros shall pay to you only your accrued but unpaid base salary for
     services rendered through the date of termination. For purposes of this
     agreement, "Cause" shall mean (i) conviction of any crime (whether or not
     involving Nephros) constituting a felony in the jurisdiction involved; (ii)
     engaging in any act which, in each case, subjects, or if generally known
     would subject, Nephros to public ridicule or embarrassment; (iii) gross
     neglect or misconduct in the performance of your duties hereunder; (iv)
     willful failure or refusal to perform such duties as may reasonably be
     delegated to you commensurate with your position; or (v) material breach by
     you of any provision of this agreement or of a Confidentiality or
     Assignment of Invention Agreement; provided, however, that with respect to
     clauses (iii), (iv) or (v), if susceptible of cure, you shall have received
     written notice from Nephros setting forth the alleged act or failure to act
     constituting "Cause" hereunder, and you shall not have cured such act or
     refusal to act within 30 business days of you receipt of such notice.

          (b)  If, as a result of your incapacity due to physical or mental
     illness, you shall have failed to perform your duties hereunder on a full
     time basis for either (i) one hundred twenty (120) days within any three
     hundred sixty-five (365) day period, or (ii) ninety (90) consecutive days,
     then Nephros may terminate your employment hereunder for "Disability". In
     that event, Nephros shall pay to you only your accrued but unpaid base
     salary for services rendered through such date of termination. During any
     period that you fail to perform your duties hereunder as a result of
     incapacity due to physical or mental illness (a "Disability Period"), you
     shall continue to receive the compensation and benefits provided by this
     agreement until your employment hereunder is terminated; provided, however,
     that the amount of compensation and benefits received by you during the
     Disability Period shall be reduced by the aggregate amounts, if any,
     payable to you under disability benefit plans and programs of Nephros or
     under the Social Security disability insurance program.

          (c)  In the event that your employment hereunder is terminated by
     Nephros prior to the expiration of the term for any reason other than as
     provided in paragraphs (a) or (b) above, then Nephros shall pay to you:

               (i)     any accrued but unpaid base salary for services rendered
               through such date of termination;

               (ii)    any unpaid bonuses due or payable on or prior to the date
               of termination or within 90 days thereafter; and

               (iii)   the continued payment of your base salary, in the amount
               as of the date of termination, for the remainder of the term and
               any Sundown Period (as defined in paragraph (d), below), such
               payments to be made at the times such base salary would have been
               paid had your employment not terminated.

          (d)  If, on or prior to six months before the date of expiration of
     the term of your employment hereunder, Nephros fails to either (i) offer to
     extend such term for at least six months or (ii) notify you that it will
     terminate your employment hereunder, then Nephros shall continue to pay you
     your base salary, in the amount as of the date of termination of your
     employment hereunder, until the earlier of (x) six months following the
     date Nephros notifies you that it will terminate your employment hereunder
     and (y) six months following the end of the term of your employment
     hereunder (the period, if any, from the end of the term of your employment
     hereunder until the earlier such date is referred to herein as the "Sundown
     Period")

     Notwithstanding anything to the contrary contained herein, in the event
that you breach the Confidentiality or Assignment of Invention Agreements at any
time, in addition to any other remedies Nephros may have therefor, Nephros 's
obligation under clauses (ii) and (iii) of paragraph (c) above or under
paragraph (d) above shall cease and your rights thereto shall terminate and
shall be forfeited.

     Other than providing the compensation provided for in this agreement, upon
termination of your employment, Nephros and its directors, officers, employees,
subsidiaries, affiliates, stockholders, successors, assigns, agents and
representatives shall have no further obligation or liability to you or any
other person under this agreement. The payment of any amounts pursuant to this
agreement (other than any payments required by law) is expressly conditioned
upon the delivery by you to Nephros of a release in form and substance
satisfactory to Nephros of any and all claims you may have against Nephros and
its directors, officers, employees, subsidiaries, affiliates, stockholders,
successors, assigns, agents and representatives arising out of or related to
your employment by Nephros and the termination of such employment.

     Your rights and obligations hereunder may not be assigned. Nephros may
assign its rights, together with its obligations, hereunder (i) to any affiliate
or (ii) to third parties in connection with any sale, transfer or other
disposition of all or substantially all of its business or assets; in any event
the obligations of Nephros hereunder shall be binding on its successors or
assigns, whether by merger, consolidation or acquisition of all or substantially
all of its business or assets.

     By accepting this position, you acknowledge that there is no other
agreement to which you are a party that would prevent you from accepting this
position on the terms and within the timeframe
