     B. Lessor and Lessee now desire to amend and restate certain  provisions of

     NOW,  THEREFORE,  for good and  valuable  consideration,  the  receipt  and
sufficiency of which is hereby  acknowledged by the parties  hereto,  Lessor and
Lessee hereby agree as follows:

     1. ADDITIONAL  PREMISES.  Lessor and Lessee agree to do and do hereby amend
the Lease to add the additional  premises  described as 4247 W. Adams,  Suite 1,

particularly  identified as the marked area shown on Exhibit "A" attached hereto
and indicated  herein by this  reference (the  "Additional  Premises") to and as
part of the  Original  Premises.  The  Additional  Premises is hereby  leased by
Lessor to Lessee  for  eighteen  (18)  months  commencing  March  1st,  2001 and
expiring  August 31st,  2002 subject to the  conditions  and  limitations of the
Lease as modified and amended by this Amendment.

     The Original  Premises and the Additional  Premises are referred to herein,
collectively, as the "Premises".

     2. BASE RENT AND OTHER CHARGES. In addition to paying the Base Rent for the
Original Premises Lessee agrees:

     (a) Lessee shall pay in advance, to Lessor, as Base Rent for the Additional
Premises,  during the Lease Term, without any offset or deduction  including all
CPI increases,  on the first day of each month, the amount $1,588.62  commencing

first of each month of the Lease Term.

     For the entire  duration of the Lease  Term,  Lessee  shall  continue to be
obligated  to make,  and shall make,  in addition to payment of Base Rent in the
time and manner  provided for in the Lease,  all sums payable as additional rent
under the terms of the Lease, and all other amounts  chargeable to or payable by
the  Lessee  under the terms of the Lease with  respect  to the entire  Premises
including without limitation the Additional Premises.

prior term expires upon each and all of the following terms and conditions:

     at least 6 and not more than 9 months,  a written notice of the exercise of
     the option to extend this Lease for said additional term, time being of the
     essence.  If said  notification  of the  exercise  of said option is not so
     given and received, the option shall automatically expire.

     of Lessee set forth in paragraph  39.1 of this Lease are conditions of this
     Option;

(c)  All of the terms and  conditions  of this Lease except  where  specifically
     modified by this option shall apply;

(d)  The monthly rent for each month of the option period shall be calculated as

     shall the  option  rent be less than the prior  term rent plus ten  percent
     (10%).

execute and deliver this Amendment, Lessee represents and warrants to Lessor the

respect;  (iii)  as of the  date  of this  Amendment,  Lessee  has not  assigned

under the Lease and have not  committed  any breach of the  Lease;  no event has
occurred  which but for the  passing  of time or for the  giving or  receipt  of
notice,  or both,  would  constitute a default under the Lease; and no notice of
default has been given under the Lease; (ix) to the best of Lessee's  knowledge,
the use,  maintenance  and operation of the Premises  comply with all applicable
federal,  state,  county or local statutes,  laws,  rules and regulations of any
governmental  authorities  relating to  environmental,  health or safety matters
(collectively, "Environmental Laws"); the Premises have not been used and Lessee
does  not  plan to use  the  Premises  for any  activities  which,  directly  or
indirectly, involve the use, generation,  treatment, storage,  transportation or
disposal of any petroleum product or any toxic or hazardous chemical,  material,
substance,  pollutant or waste; Lessee has not received any notices,  written or
oral, of violation of any  Environmental  Laws or of any  allegation  which,  if
true,  would  contradict  anything  contained in this Amendment and there are no
writs, injunctions,  decrees, orders or judgments outstanding,  and no lawsuits,
claims,  proceedings or  investigations  pending or threatened  against  Lessee,
relating to the use,  maintenance  or operation of the  Premises,  nor is Lessee
aware of a basis for any such  proceeding;  (x) all  obligations of Lessor under
the Lease to  construct  improvements  on, and to make  repairs to, the Premises
have been  performed by Lessor and accepted by Lessee,  and Lessee has no claims
against Lessor in connection therewith.

     5.  CONTINUATION OF LEASE:  ENTIRE  AGREEMENT.  Except as hereby  expressly
amended,  the terms and conditions of the Lease shall continue in full force and
effect and the Lease is hereby ratified and affirmed.  Nothing herein  contained
alters or amends any required  consents or approval  required under the terms of
the Lease in  connection  with any sublease or  assignment.  Submission  of this
Amendment by one party to another shall have no legal significance and is not an
offer that may be accepted;  this  Amendment  shall become  effective  only upon
