EXHIBIT D

                                    GUARANTY

     In  consideration of, and as a material inducement to, BRE/METROCENTER LLC,
a Delaware limited liability company, (the "Landlord"), executing and delivering
simultaneously  herewith,  in  reliance  upon  this Guaranty, that certain Lease
dated  August  ___, 2002 (the "Lease"), between Landlord and DCA OF CHEVY CHASE,
LLC,  a  Maryland  limited  liability  company  (the "Tenant"), the undersigned,
DIALYSIS CORPORATION OF AMERICA, a Florida corporation (the "Guarantor"), hereby
unconditionally  and  absolutely  guarantees  unto  Landlord, its successors and
assigns,  the  full,  prompt  and  complete payment by Tenant of the Rent (which
shall  include  only  the  Basic Monthly Rent, additional rent, increases in the
Basic  Cost  over the Initial Cost, increases in ground rent payments, utilities
and similar rental payments, but exclusive of reimbursements and charges for any
other  defaults  or other failures by Tenant to perform under the Lease) payable
by  Tenant  during  the  first  two  (2)  lease  years of the Term of the Lease.

     Guarantor  does  hereby waive notice of any and all defaults on the part of
Tenant,  waives acceptance and notice of acceptance of this Guaranty, and waives
all  demands  for payment and/or performance; and Guarantor agrees that no delay
on  the part of Landlord in enforcing any of its rights or remedies or insisting
thereupon,  nor any extension of time nor any changes or modifications in or to,
or  in  connection  with the Lease, shall in any way limit, affect or impair the
liability of Guarantor hereunder; and Guarantor hereby expressly consents to and
approves  thereof  with  the same force and effect as though its written consent
had  been  given  to each of such delays, extensions, changes and modifications.
GUARANTOR  DOES  HEREBY  WAIVE  ITS  RIGHT  TO  TRIAL  BY  JURY IN ANY ACTION OR
COUNTERCLAIM  BROUGHT BY LANDLORD ON ANY MATTERS WHATSOEVER ARISING OUT OF OR IN
ANY  WAY  CONNECTED WITH THE LEASE, THE USE AND OCCUPANCY OF THE PREMISES, OR IN
ANY  WAY  CONNECTED  WITH  THIS  GUARANTY.

     This  Guaranty  is  independent of and in addition to any security or other
remedies  which  Landlord  has  or  may  have  for the performance of any of the
obligations  on the part of Tenant; and Guarantor agrees that Landlord shall not
be  required to resort to any other security or other remedies before proceeding
upon this Guaranty, but that Landlord may proceed hereunder against Guarantor at
any  time  it sees fit, independently of or concurrently with any other remedies
it  may  have.

     If Guarantor is a corporation and is merged into or with any other company,
firm  or  corporation,  the  resulting merged company, firm or corporation shall
become  liable  as  Guarantor  under  this  Guaranty  to  the same extent as the
original  named  Guarantor  hereunder.

     If  Guarantor  is a corporation or a partnership (general or limited), firm
or  other  entity,  the officers or parties executing this Guaranty on behalf of
the  Guarantor hereby jointly and severally warrant and represent that Guarantor
has full power and authority to guarantee the Lease and to make and execute this
Guaranty  and that this Guaranty is fully and legally binding upon Guarantor and
its  property  and  assets.

     If  this  Guaranty  is  executed  by two or more corporations, individuals,
firms,  partnership  (general  or limited) or other entities (or any combination
thereof)  the  liability  of said parties executing this Guaranty shall be joint
and  several.

     This  Guaranty  shall  be  binding  upon the undersigned, the undersigned's
successors  and  assigns,  and  shall  inure  to  the  benefit  of Landlord, its
successors  and assigns, and to the benefit of any successors to the interest of
Landlord  under  the  Lease and/or to the Building in which the premises demised
under  the  Lease  are  situate.

     Despite  the  foregoing,  (a)  Guarantor's liability under this Guaranty is
limited  to  the  sum of (i) the Rent (as defined in the first paragraph of this
Guaranty)  that  is payable under the first two (2) lease years of the Term (and
no other obligations of Tenant) and (ii) all reasonable attorneys' fees incurred
by  Landlord in connection with enforcing the Guarantor's obligations under this
Guaranty,  and (b) from and after the date that Tenant has fully paid all of the
Rent  that  is due under the Lease during the first (1st) two (2) lease years of
the  Term,  this  Guaranty  shall  be  of  no  further  force  or  effect.

     IN  WITNESS  WHEREOF, the undersigned has duly executed this Guaranty under
seal  as  of  the  ___  day  of  August  _____,  2002.
