                              EMPLOYMENT AGREEMENT


         This Agreement by and between KERYX BIOPHARMACEUTICALS, INC. ("Keryx"),
a Delaware corporation having an address at 5 Kiryat Mada, Har Hotzvim,
Jerusalem, Israel 91236 and ROBERT GALLAHUE, JR., an individual residing at 544
Sharpner's Pond Road, North Andover, Massachusetts 01845 United States of
America ("Gallahue").

WITNESSETH:

         WHEREAS, the Corporation desires to employ Gallahue as Chief Financial
Officer and Treasurer of Keryx and Gallahue desires to be employed by the Keryx
as Chief Financial Officer and Treasurer of Keryx, all pursuant to the terms and
conditions hereinafter set forth;

         NOW THEREFORE, in consideration of the foregoing and the mutual
promises and covenants herein contained, it is agreed as follows:


1.       EMPLOYMENT DUTIES

         Keryx hereby engages and employs Gallahue, and Gallahue accepts
engagement and employment, as Chief Financial Officer and Treasurer of Keryx, to
direct, supervise and have responsibilities for the financial affairs of Keryx
and for any other appropriate areas and tasks which the Board of Directors
and/or the Chief Executive Officer may assign to him. Gallahue acknowledges and
agrees that the performance by Gallahue of his duties hereunder may require
significant domestic and international travel by Gallahue.

2.       TERM

         Gallahue's employment hereunder shall be for a term of three (3) years
commencing on June 29, 2000, and continuing through June 29, 2003 (the "Initial
Term"), with successive one-year renewals thereafter (the "Renewal Terms")
unless sooner terminated as hereinafter provided. (The Initial Term and Renewal
Terms are collectively referred to as the "Term.")

3.       COMPENSATION

         (a) As compensation for the performance of his duties on behalf of
Keryx, Gallahue shall be compensated as follows:

              (i) BASE SALARY. Gallahue shall receive an annual gross base
salary of one hundred and fifty thousand dollars ($150,000) payable in
accordance with the Corporation's payroll policies and subject to standard
payroll deductions and withholdings. The Corporation's Board of Directors shall
review Gallahue's performance and the Corporation's financial and operating
results on at least an annual basis, and may increase Gallahue's base salary as
it, in its reasonable discretion, deems appropriate based on such review.

              (ii) BONUS. Gallahue shall be eligible to receive one or more
bonuses during any calendar year in the discretion of the Chief Executive
Officer, acting in consultation with the Board of Directors.

              (iii) EQUITY. The Corporation will grant Gallahue options (the
"Options") to purchase 90,000 shares of the common stock of the Corporation (the
"Initial Grant") at an exercise price equal to $10.00 per share (the "Exercise
Price"), which options shall be exercisable for a period of 10 years from the
date of issuance. The Initial Grant and the Exercise Price give effect to the
Corporation's one-for-two common stock dividend declared by the Board of
Directors on June 14, 2000 (the "June 2000 Stock Dividend"). Gallahue's Options
will be granted under the Corporation's 2000 Stock Option Plan (the "Plan") and
will be subject to the terms and conditions thereof, including any Stock Option
Agreement entered into by Gallahue and the Corporation thereunder. In accordance
with the Plan, should any change be made to the Common Stock by reason of any
stock split, stock dividend


<PAGE>

(other than the June 2000 Stock Dividend, for which such adjustment has already
been made), recapitalization, combination of shares, exchange of shares or other
change affecting the outstanding Common Stock as a class without the
Corporation's receipt of consideration, appropriate adjustments shall be made to
(A) the total number and/or class of securities subject to such options and (B)
the Exercise Price in order to reflect such change and thereby preclude a
dilution or enlargement under such options. One-third of the Initial Grant shall
vest on each anniversary date following the grant date of such options, provided
that at the time of vesting, Gallahue is employed by the Corporation or by a
parent, subsidiary or affiliate of the Corporation.

         (b) EXPENSES. Keryx shall reimburse Gallahue for all normal, usual and
necessary expenses incurred by Gallahue in furtherance of the business and
affairs of Keryx, including travel and entertainment, against receipt by Keryx
of appropriate vouchers or other proof of Gallahue's expenditures and otherwise
in accordance with such Expense Reimbursement Policy as may from time to time be
adopted by the Board of Directors of Keryx.

         (c) ANNUAL LEAVE AND HOLIDAYS. Gallahue shall be entitled during the
term of this Agreement to twenty (20) business days of annual leave per year as
well as the following holidays: New Year's Day, President's Day, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day and the day following, and
Christmas Day.

         (d) EMPLOYEE BENEFITS. During the Term of his employment, Gallahue
shall be entitled to participate in all employee and fringe benefit plans and
programs generally offered to other members of the Corporation's management who
are similarly situated, including, without limitation, any pension, profit
sharing, incentive, retirement, insurance, health and disability benefits and
plans. The Corporation reserves its right to modify or terminate any of its
employee and fringe benefit plans and programs at any time.

4.       REPRESENTATIONS AND WARRANTIES
         BY GALLAHUE AND KERYX

         (a) Gallahue hereby represents and warrants to Keryx as follows:

              (i) Neither the execution and delivery of this Agreement nor the
performance by Gallahue of his duties and other obligations hereunder violate
any statute, law, determination or award, or conflict with or constitute a
default under (whether immediately, upon the giving of notice or lapse of time
or both) any prior employment agreement, contract, or other instrument to which
Gallahue is a party or by which he is bound.

              (ii) Gallahue has the full right, power and legal capacity to
enter and deliver this Agreement and to perform his duties and other obligations
hereunder. This Agreement constitutes the legal, valid and binding obligation of
Gallahue enforceable against him in accordance with its terms. No approvals or
consents of any persons or entities are required for Gallahue to execute and
deliver this Agreement or perform his duties and other obligations hereunder.

              (iii) Gallahue will devote his entire business time, energy,
abilities and experience to the performance of his duties, effectively and in
good faith. Further, during the Term, Gallahue shall not render services as an
employee, consultant or otherwise, whether or not during regular business hours,
for pay to any other party other than the Corporation without the written
permission of the Chief Executive Officer.

         (b) Keryx hereby represents and warrants to Gallahue as follows:

              (i) Keryx is duly organized, validly existing and in good standing
under the laws of the State of Delaware, with all requisite corporate power and
authority to own its properties and conduct its business in the manner presently
conducted.

              (ii) Keryx has the full power and authority to enter into this
Agreement and to incur and perform its obligations hereunder.


<PAGE>

              (iii) The execution, delivery and performance by Keryx of this
Agreement does not conflict with or result in a material breach or violation of
or constitute a material default under (whether immediately, or upon the giving
of notice or lapse of time or both) the certificate of incorporation or by-laws
of Keryx, or any agreement or instrument to which Keryx is a party or by which
Keryx or any of its properties may be bound or affected.

5.       CONFIDENTIAL INFORMATION

         Gallahue agrees to sign and comply with the Corporation's Proprietary
Information and Inventions Agreement, annexed hereto as Exhibit A.

6.       NON-COMPETITION

         (a) Gallahue understands and recognizes that his services to Keryx are
special and unique and agrees that, during the Term, and for a period of 12
months from the date of termination of his employment hereunder, he shall not in
any manner, directly or indirectly, on behalf of himself or any person, firm,
partnership, joint venture, corporation or other business entity ("Person"),
enter into or engage in any business directly competitive with Keryx's business,
either as an individual for his own account, or as a partner, joint venturer,
treasurer, agent, consultant, salesperson, officer, director or shareholder of a
Person operating or intending to operate within the area that Keryx is, at the
date of termination, conducting its business (the "Restricted Businesses");
provided, however, that nothing herein will preclude Gallahue from holding one
percent (1%) or less of the stock of any publicly traded Corporation.

         (b) In the event that Gallahue breaches any provisions of this Section
6 or there is a threatened breach, then, in addition to any other rights which
Keryx may have, Keryx shall be entitled, without the posting of a bond or other
security, to injunctive relief to enforce the restrictions contained herein. In
the event that an actual proceeding is brought in equity to enforce the
provisions of this Section 6, Gallahue shall not argue as a defense that there
is an adequate remedy at law nor shall Keryx be prevented from seeking any other
remedies that may be available.

7.       NON-SOLICITATION AND NON-INTERFERENCE

         During the Term, and for 12 months thereafter, Gallahue shall not,
directly or indirectly, without the prior written consent of Keryx:

         (a) solicit or induce any employee of Keryx or any subsidiary, parent,
affiliate or successor ("Affiliate") of Keryx to leave the employ of Keryx or
any Affiliate or hire for any purpose any employee of Keryx or any Affiliate or
any employee who has left the employment of Keryx or any Affiliate within six
months of the termination of said employee's employment with Keryx; or

         (b) interfere with or disrupt or attempt to disrupt Keryx's or its
Affiliates' business relationship with any of their partners, service providers,
clients, customers and/or suppliers.

8.       TERMINATION

         (a) Either party may terminate Gallahue's employment with the
Corporation without cause at any time upon ninety (90) days' notice. The
Corporation shall have the right, in its sole discretion, to require Gallahue to
continue working for the Corporation during the notice period. If the Employer
terminates the Employee without cause pursuant to this section, and only if
Gallahue executes a waiver and release of claims substantially in the form set
forth in Exhibit B, attached hereto, the Board of Directors shall take the
necessary steps so that (i) any outstanding, but unvested, options granted to
the Employee shall vest upon the effective date of his termination; and (ii) the
period during which the Employee shall be permitted to exercise such options
shall be extended to two (2) years from the effective date of his termination as
defined in the Stock Option Plan governing the options in question.

         (b) Gallahue's employment shall be terminated by his death or
disability. (For purposes of this section, "disability" shall be deemed to have
occurred if Gallahue is unable, due to any physical

<PAGE>

or mental disease or condition, to perform his normal duties of employment for
120 consecutive days or 180 days in any twelve-month period.) In such an event,
he shall be entitled to continue to receive his base salary for three (3) months
following his last day of actual employment by the Corporation. In addition, the
Board of Directors shall take the necessary steps so that (a) any outstanding,
but unvested, options granted to the Employee shall vest upon the effective date
of his termination; and (b) the period during which the Employee shall be
permitted to exercise such options shall be extended to two (2) years from the
effective date of his termination as defined in the Share Option Plan governing
the options in question. Should the Employee's employment be terminated as a
result of his death, the benefits granted herein, shall be granted instead to
his lawful heir or heirs. In either case (disability or death), accelerated
vesting and extended exercise of the options will only be granted if Gallahue
or, in the case of his death, his legal successor, together with his lawful heir
or heirs, execute a waiver and release of claims substantially in the form set
forth in Exhibit B hereto.

         (c) Notwithstanding the foregoing, the Corporation may terminate
Gallahue immediately and without prior notice in the following circumstances:
(a) a material breach of Gallahue's obligations pursuant to Sections 4(a), 5, 6
and/or 7; (b) a material breach by Gallahue of any other provision of this
Agreement, which is not cured by Gallahue within fifteen (15) days after
receiving notice thereof from the Corporation containing a description of the
breach or breaches alleged to have occurred; (c) the habitual neglect or gross
failure by Gallahue to adequately perform the duties of his position; (d) any
act of moral turpitude or criminal action connected to his employment with the
Corporation or his place of employment; or (e) Gallahue's refusal to comply with
or his violation of lawful instructions of the Chief Executive Officer or the
Board of Directors.

         (d). In the event that Gallahue's employment has been terminated in
accordance with Section 8(c), above, Gallahue shall not be entitled to receive
any of the severance benefits set forth in Section 8(a) or (b), above.

9.       INDEMNIFICATION

         The Corporation shall take whatever steps are necessary to establish a
policy of indemnifying its officers, including, but not limited to Gallahue, for
all actions taken in good faith in pursuit of their duties and obligations to
the Corporation. Such steps shall include, but shall not necessarily be limited
to, the obtaining of an appropriate level of Directors and Officers Liability
coverage.

10.      NOTICES

         Any notice or other communication under this Agreement shall be in
writing and shall be deemed to have been given when delivered personally against
receipt thereof; two (2) business days after being sent by Federal Express or
similar internationally recognized courier service; or seven (7) business days
after being mailed registered or certified mail, postage prepaid, return receipt
requested, to either party at the address set forth above, or to such other
address as such party shall give by notice hereunder to the other party.

11.      SEVERABILITY OF PROVISIONS

         If any provision of this Agreement shall be declared by a court of
competent jurisdiction to be invalid, illegal or incapable of being enforced in
whole or in part, the remaining conditions and provisions or portions thereof
shall nevertheless remain in full force and effect and enforceable to the extent
they are valid, legal and enforceable, and no provision shall be deemed
dependent upon any other covenant or provision unless so expressed herein.

Gallahue and his legal representatives. This Agreement constitutes a personal
service agreement, and the performance of Gallahue's obligations hereunder may
not be transferred or assigned by Gallahue.

14.      NON-WAIVER

         The failure of either party to insist upon the strict performance of
any of the terms, conditions and provisions of this Agreement shall not be
construed as a waiver or relinquishment of future compliance therewith, and said
terms, conditions and provisions shall remain in full force and effect. No

shall be effective for any purpose whatsoever unless such waiver is in writing
and signed by such party.

and/or 7 of this Agreement by him could cause irreparable damage to Keryx and to
the Affiliates, and that monetary damages alone would not be adequate and, in
the event of such breach, Keryx shall have, in addition to any and all remedies
of law, the right to an injunction, specific performance or other equitable
relief to prevent or redress the violation of Keryx's rights under such
Sections.

                                    EXHIBIT A

                PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT


         In consideration of my employment or continued employment by Keryx
Biopharmaceuticals, Inc. (together with any subsidiary of Keryx
Biopharmaceuticals, Inc., the "Company"), and the compensation now and hereafter
paid to me, I hereby agree as follows:

         1. RECOGNITION OF COMPANY'S RIGHTS; NONDISCLOSURE. At all times during
the term of my employment and thereafter, I will hold in strictest confidence
and will not disclose, use, lecture upon or publish any of the Company's
Proprietary Information (defined below), except as such disclosure, use or
publication may be required in connection with my work for the Company, or
unless an officer of the Company expressly authorizes such in writing.

         The term "Proprietary Information" shall mean trade secrets,
confidential knowledge, data or any other proprietary information of the
Company. By way of illustration but not limitation, "Proprietary Information"
includes (a) inventions, mask works, trade secrets, ideas, processes, formulas,
source and object codes, data, programs, other works of authorship, know-how,
improvements, discoveries, developments, designs and techniques (hereinafter
collectively refereed to as "Inventions"); and (b) information regarding plans
for research, development, new products, regulatory matters, marketing and
selling, business plans, budgets and unpublished financial statements, licenses,
prices and costs, suppliers and customers; and information regarding the skills
and compensation of other employees of the Company.

         2. THIRD PARTY INFORMATION. I understand, in addition, that the Company
has received, and in the future will receive, from third parties confidential or
proprietary information ("Third Party Information") subject to a duty on the
Company's part to maintain the confidentiality of such information and to use it
only for certain limited purposes. During the term of my employment and
thereafter, I will hold Third Party Information in the strictest confidence and
will not disclose to anyone (except in connection with my work for the Company),
unless expressly authorized by an officer of the Company in writing.

         3.  ASSIGNMENT OF INVENTIONS

              3.1  ASSIGNMENT

                (a) I hereby assign to the Company all my right, title and
interest in and to any and all Inventions and all patent rights, copyrights,
mask work rights, trademarks, trade secret rights, all other rights throughout
the world in connection therewith, and the goodwill associated with all of the
foregoing (collectively, "Proprietary Rights"), whether or not patentable or
registrable under patent, copyright, trademark or similar statutes, made or
conceived or reduced to practice or learned by me, either alone or jointly with
others, during the period of my employment with the Company. Inventions assigned
to, or as directed by, the Company under this Paragraph 3 are hereinafter
referred to as "Company Inventions". I agree, upon request, to execute, verify
and deliver assignments of the Proprietary Rights to the Company or its designee
and I hereby appoint the Company my attorney-in-fact with respect to the
Proprietary Rights for the purpose of effecting any or all of the Company's
rights to the Proprietary Rights.

              3.1 GOVERNMENT. I also agree to assign to or as directed by the
Company all my right, title and interest in and to any and all Inventions, full
title to which is required to be assigned to the United States of America by a
contract between the Company and United States of America or any of its
agencies.

              3.2 WORKS FOR HIRE. I acknowledge that all original works of
authorship which are made by me (solely or jointly with others) within the scope
of my employment and which are protectable by copyright are "works made for
hire", as that term is defined in the United States Copyright Act (17 U.S.C.
Section 101).

<PAGE>

         4. ENFORCEMENT OF PROPRIETARY RIGHTS. From time to time, I will assist
the Company in every proper way to obtain and enforce United States and foreign
Proprietary Rights relating to Company Inventions in any and all countries. My
obligation to assist the Company with respect to Proprietary Rights relating to
such Company Inventions in any and all countries shall continue beyond the
termination of my employment, but the Company shall compensate me at a
reasonable rate after my termination for the time actually spent by me at the
Company's request on such assistance.

         I hereby waive and quitclaim to the Company any and all claims, of any
nature whatsoever, which I now or may hereafter have for infringement of any
Proprietary Rights assigned hereunder to the Company.

         5. OBLIGATION TO KEEP COMPANY INFORMED. During the period of my
employment, I will promptly disclose all Inventions to the Company fully and in
writing and will hold such Inventions in trust for the sole right and benefit of
the Company. In addition, after termination of my employment, I will promptly
disclose all patent applications filed by me within a year after termination of
employment.

         6. PRIOR INVENTIONS. Inventions, if any, patented or unpatented, which
I made prior to the commencement of my employment with the Company are excluded
from the scope of this Agreement. To preclude any possible uncertainty, I have
set forth in Exhibit A attached hereto a complete list of all Inventions (i)
that I have, alone or jointly with others, conceived, developed or reduced to
practice or caused to be conceived, developed or reduced to practice prior to
the commencement of my employment with the Company, (ii) that I consider to be
my property or the property of third parties and (iii) that I wish to have
excluded from the scope of this Agreement. If disclosure of any such Invention
on Exhibit A would cause me to violate any prior confidentiality agreement, I
understand that I am not to list such Inventions in Exhibit A but am to inform
the Company that all such Inventions have not been listed for that reason.

         7. NO IMPROPER USE OF MATERIALS. During my employment by the Company, I
will not improperly use or disclose any confidential information or trade
secrets, if any, of any former employer or any other person to whom I have an
obligation of confidentiality, and I will not bring onto the premises of the
Company any unpublished documents or any property belonging to any former
employer or any other person to whom I have an obligation of confidentiality
unless consented to in writing by that former employer or person.

         8. NO CONFLICTING OBLIGATION. I represent that my performance of all
the terms of this Agreement and my performance of my duties as an employee of
the Company do not and will not breach any agreement to keep in confidence
information acquired by me in confidence or in trust prior to my employment by
the Company. I have not entered into, and I agree I will not enter into, any
agreement either written or oral in conflict herewith.

         9. RETURN OF COMPANY DOCUMENTS. When I leave the employ of the Company,
I will deliver to the Company any and all drawings, notes, memoranda,
specifications, devices, formulas, molecules, cells, storage media, including
software, documents and computer printouts, together with all copies thereof,
and any other material containing or disclosing any Company Inventions, Third
Party Information or Proprietary Information of the Company. I further agree
that any property situated on the Company's premises and owned by the Company,
including disks and other storage media, filing cabinets or other work areas, is
subject to inspection by Company personnel at any time with or without notice.
Prior to leaving, I will cooperate with the Company in completing and signing
the Company's termination statement for technical and management personnel.

         10. LEGAL AND EQUITABLE REMEDIES. Because my services are personal and
unique and because I may have access to and may become acquainted with the
Proprietary Information of the Company, the Company shall have the right to
enforce this Agreement and any of its provisions by injunction, specific
performance or other equitable relief, without bond, without prejudice to any
other rights and remedies that the Company may have for a breach of this
Agreement, and I waive the claim or defense that the Company has an adequate
remedy at law. I shall not, in any action or proceeding to enforce any of the
provisions of this Agreement, assert the claim or defense that such an adequate
remedy at law exists.

<PAGE>

         11. NOTICES. Any notices required or permitted hereunder shall be given
to me at the address specified below or at such other address as I shall specify
in writing. Such notice shall be deemed given upon personal delivery to the
appropriate address or if sent by certified or registered mail, three days after
the date of mailing.

         12. GENERAL PROVISIONS.

be governed by and construed according to the laws of the Commonwealth of
Massachusetts.

              12.2 ENTIRE AGREEMENT. This Agreement is the final, complete and
exclusive agreement of the parties with respect to the subject matter hereof and
supersedes and merges all prior discussions between us. No modification or
amendment of this Agreement, nor any waiver of any rights under this Agreement,
will be effective unless in writing, signed by the party to be charged. Any
subsequent change or changes in my duties, salary or compensation will not
affect the validity or scope of this Agreement. As used in this Agreement, the
period of my employment includes any time during which I may be retained by the
Company as a consultant.

              12.3 SEVERABILITY. If one or more of the provisions in this
Agreement are deemed unenforceable by law, then the remaining provisions will
continue in full forced and effect.

              12.4 SUCCESSORS AND ASSIGNS. This Agreement will be binding upon
my heirs, executors, administrators and other legal representatives and will be
for the benefit of the Company, its successors, and its assigns. I may not
assign any of my rights, or delegate any of my obligations, under this
Agreement.

              12.5 SURVIVAL. The provisions of this Agreement shall survive the
termination of my employment and the assignment of this Agreement by the Company
to any successor in interest or other assignee.

              12.6 EMPLOYMENT. I agree and understand that nothing in this
Agreement shall confer on me any right with respect to continuation of my
employment with the Company, or shall it interfere in any way with my right or
the Company's right to terminate my employment at any time, with or without
cause.

              12.7 WAIVER. No waiver by the Company of any breach of this
Agreement shall be a waiver of any preceding or succeeding breach. No waiver by
the Company of any right under this Agreement shall be construed as a wavier of
any other right. The Company shall not be required to give notice to enforce
strict adherence to all terms of this Agreement.

              12.8 COUNTERPARTS. This Agreement may be executed in counterparts,
all of which together shall for all purposes constitute one Agreement, binding
