    Further  renovation  of the object  for  contractually  stipulated  use is
    responsibility  of  the  tenant.   The  landlord  approves  the  measures,
    provided no  manipulation  of the  building  substance  takes  place.  The
    renovation consists mainly of expansion of the sprinkler  installation for
    shelves.

    The landlord  guarantees  that the rental property is suitable to meet the
    requirements  to  fulfil  the  contractually   intended  purpose  in  both
    constructional  and legal  aspects,  at the point of  contract  begin,  in
    terms of type, situation, quality and condition.

    any necessary permits, concessions,  approvals and other papers, as far as
    these stand in connection with his person or employer.

    the enclosed inventory list, Attachment 3.
3.    The  following  keys will be handed  over to the  tenant  upon  contract

1.    Rental is expected to begin on 01.01.2004 and end on 31.12.2008.

2.    The tenant is entitled to demand in written  form a five-year  extension
   (option) of the rental  contract,  of which the landlord must be in receipt
   at least 12 months  prior to  termination  of the rental  contract.  Within
   this  period of time,  the tenant is  entitled  to give  notice of contract
   with 12 months notice to the end of each year.
3.    If the  tenant  makes  use of his  right  to  option,  the  contract  is
   extended  by one year at a time  following  expiry of the  contract  period
   including the option  period,  that is,  following 10 years since  contract
   begin,  unless a  contracting  party  objects to the  extension  in writing
   with 12 months notice .


Investments  made  by the  landlord  to the  benefit  of the  tenant  will  be
compensated  upon  termination  of the contract  according to the agreed terms
of ss. 15 subsection 3.

After  termination of the rental  contract,  an implied  extension of contract
according to ss. 568 BGB (civil code) will not be considered.


                      ss. 3 Revocation/Exceptional Notice

The  parties  are  aware  that the  permits  under  public  law for the  legal
generation of the rental  property  have not yet been issued.  The landlord is
entitled to revoke the  agreement or give notice if the  required  permits are
not  issued.  The  tenant is not  entitled  to  submit a damage  claim in such
case.  Revocation or submission of notice must take place in writing,  without
time limit.  The landlord may give immediate  notice with immediate effect for
important  reasons,  especially  in the case of  continued  use of the  rental
property  in  violation  of  the  contract   despite  a  warning  or  repeated
violation  of  the   contract,   insolvency   of  the  tenant  or   insolvency
proceedings having commenced with reference to the assets of the tenant.

                       ss. 4 Rent and Operating Expenses

1.    The annual basic rent amounts to (euro)500 000.00,
    at contract begin the monthly rent amounts to :
     a) basic rent                               41 666.50      EURO
     b) advance payment for operating expenses EURO 1,00/m(2) x 9742 m(2)  =
     9742.00 EURO
     c) current valid turnover tax on  a) and b) currently 16%   EURO
     Total:                                                     EURO








2.    By mutual agreement,  the rented useful floor space has been established
    to be approx. 9742m(2) for calculation  purposes.  The useful floor space is
    the sum of the  secondary  useful  surfaces  and the primary  usable floor
    space  according  to DIN  277  with  reference  to the  architects  plans.
    Deviations  of  up  to  5  %  from  the  actual  useful  floor  space  are
    acceptable.   The  entire   usable   floor  space  of  the   building  has
    provisionally  been  established to be approx.  42790 m(2) gross. The useful
    floor space of the rental  property thus initially  corresponds to 21.99 %
    of the  useful  floor  space of the entire  building.  The tenant is aware
    that within the process of  converting  the  function of the  building the
    proportion of the surfaces of the rental  property to the entire  property
    has  not  been  finally  established.   The  required  adaptation  of  the
    proportion  will be  undertaken  by the  landlord  according  to his  fair
    judgement.
3.    The tenant also carries the  operating  costs acc. to  Attachment 3 of ss.
    27  subsection  1 of the Second  Computation  Ordinance  in the  currently
    valid version  (enclosure in Attachment 4) , insofar as they are allocable
    to the tenant.  Payments  made by the  landlord  may be factored  into the
    determination  of  operating  and  administrative  expenses  and costs for
    special services in the amount of the costs saved for comparable  services
    performed by Third Parties,  but without  accounting for turnover tax. For
    the  duration of the rental  contract the landlord is entitled to transfer
    newly incurred  operating costs,  taxes and fees to the tenant,  as far as
    this point was subjected to true assessment by the contracting  parties at
    contract begin.
4.    In as far  as it is  possible  to be  invoiced  directly  by  energy  or
    service suppliers, the tenant is obliged to do so.

5.    The following cost assessment formula applies:
a)    Recording of consumption/use according to consumption
b)    For overlapping  areas,  recording of  consumption/use  according to use
           and, for example, useful surface area.
c)    According to useful surface area for all other.

    The landlord may change the cost  assessment  formula acc. to his own fair
    judgement,  provided  this is  justifiably  in his  interest  and mutually
    agreed.

6.    The tenant transfers  monthly advance  payments for operating  expenses,
    which are  balanced  annually by the  landlord..  The  landland  can alter
    payment  intervals if justified  by practical  considerations.  The tenant
    receives annually a specified record of expenses.

7.    Each party to the contract may, following  balancing of annual accounts,
    demand  reasonable  adjustment  to  the  sum  of the  advance  payment  of
    operating expenses, in writing

                           ss. 5 Change in Basic Rent








1.    As a  precautionary  measure,  the landlord  declares his  obligation to
    obtain a negative  attestation from the Bundesamt fur Wirtschaft (,,Federal
    Department of Economy")  (Address:  Bundesamt fur Wirtschaft,  Ref. III 6,
    Frankfurterstrasse  29/31,  65760  Eschborn.)  The parties agree that each
    contracting  party may demand  adjustment  of the amount of basic rent, if
    the  official  cost of  living  index  issued  by the  Federal  Bureau  of
    Statistics,  , based on 100 from  the  year  1995,  changes  by at least 5
    points  compared  to the  index  applying  at the time of  signing  of the
    contract,  or compared to a previous  increase.  The change is  determined
    according to rental rates  applying to comparable  objects  rented for the
    first time in similar locations  (adjustment clause).  Insofar as no other
    agreement  has been made,  the  change in basic rent  applies in the month
    following  the demand for  adjustment..  Should an  agreement  between the
    parties  not  be  forthcoming  within  a  month,  an  official  appraiser,
    publicly  appointed and sworn in by the  responsible  chamber of commerce,
    will  determine  the  amount  of  the  new  basic  rent  upon  application
    submitted by one of the  contracting  parties.  The costs of the appraiser
    will be born equally by both parties.


                             ss. 6 Security Deposit

1.    The tenant is obliged to pay to the  landlord,  to cover all claims made
   by the  landlord in  connection  with the rental  agreement,  a security in
   form  of  directly  liable,   irrevocable,   unlimited  and   unconditional
   guarantee  drawn on a major bank or public  savings  institute at the value
   of half the annual basic rent,  that is 250.000 EURO.  Upon increase of the
   basic rent,  the  security  deposit will be increased if so demanded by the
   landlord. .

2.    The tenant must hand over the written  commitment to a bank guarantee to
   the  landlord  prior to  surrender  of the  rental  property.  Should  this
   commitment  not be  forthcoming  in  spite  of  warning,  the  landlord  is
   entitled to revoke the rental contract or give immediate notice.

3.    The landlord is entitled to make use of the security  deposit during the
   rental  period  even  if  the  tenant  has  objected  to the  claim  by the
   landlord.  The landlord  can require the tenant to  replenish  the depleted
   security deposit to meet the sum agreed on in the contract.

                     ss.7 Rental Payment and Extra Charges

1.    The rent including  operating  costs is payable to the landlord  monthly
    in advance,  without  charges,  on the third working day of the month,  as
    follows.
         Recipient:  ........................
         Account No.:........................
         Credit Institute:........................
         Bank Code No:    ........................

2.    Upon request by the landlord,  the tenant is obligated to effect payment
    by  automatic  deduction  by the credit  institute.  By repeated  delay in
    payment the tenant may not derive entitlement to delayed payment.


                  ss. 8 Reduction, Set-Off, Right of Retention







1.    The tenant can only effect  set-off or  reduction  or retention by means
   of a  counter-claim  to the claims by the landlord  based on this contract,
   on the condition that his  counter-claim  is  undisputed,  legally valid or
   ripe  for  judgement.   Set-off,   reduction  or  exercising  of  right  to
   retention  are only  admissible  if the tenant has notified the landlord in
   writing of his intention at least one month prior to due date of rent.

2.    A set-off,  reduction or  retention of the advance  payment of operating
   expenses by the tenant is not admissible.


           ss. 9 Interior Redecoration, Minor Repairs and Maintenance

1.    Interior  redecoration  is  undertaken  by the tenant  during the rental
      period.  This comprises  expert painting of walls and ceilings,  heating
      elements,   panelling,   windows,   inner  and  outer  doors.   Interior
      redecoration  is to be  carried  out as soon as the  degree  of wear and
      tear  warrants such action.  The tenant is further  obligated to ensure,
      when  necessary,  expert  treatment  of the present  flooring  including
      bordering, and renewal if necessary.

2.    The tenant bears the costs for minor  maintenance and repair work on and
      within the rented  property up to a sum of 5 % of the net  monthly  rent
      for single  measures  and  limited to an annual  maximum of
      (euro) 10 000.00. Necessary  maintenance  measures  are  carried
      out by the tenant and the costs carried by him.



                       ss. 10 Constructional Alterations

1.    Constructional  alterations  effected  by the tenant must be approved by
   the  landlord.  Action  taken  without  this  approval  must  be  retracted
   immediately  upon  request by the  landlord,  by the tenant at the tenants'
   costs  whereby  the  building  must be restored to its  original  state.  .
   Following  warning  with no reaction  within a  reasonable  period of time,
   the  landlord  is  entitled  to  take  action  at the  tenants'  cost.  The
   landlords'  right to demand  restoration  at tenants'  cost of the original
   constructional   state   following  end  of  the  rental  period,   is  not
   influenced  by any  approval  he has issued for  constructional  changes by
   the   tenant.   The  tenant  is  liable  for  all   damage   arising   from
   constructional measures he has undertaken.
2.    Externally  visible  advertising on the rental property must be approved
   by the landlord.  At the end of the rental period the original  state is to
   be restored,  with no claim to reimbursement of costs,  irrespective of any
   approval issued by the landlord for advertising actions.

                         ss. 11 Liability of the Tenant







1.    The tenant is liable to the  landlord for damage to the rented rooms and
    building  as  well  as  to  the  rented  rooms  or  the   facilities   and
    installations  belonging to the  buildings/economic  entity, caused by him
    or  persons in the  warehouse,  as far as he can be held to  account.  The
    tenant must provide proof that culpable  conduct did not take place, in as
    far as rooms,  facilities and installations  fall within his custody.  The
    tenant is liable for accidents or acts of God.

2.    The tenant is  responsible  for  traffic  safety  measures in the rented
    facilities  and  surfaces.  The tenant  releases the landlord  from claims
    arising from  violation of the traffic  safety  obligations,  provided the
    landlord cannot also be held responsible.

3.    The tenant is obligated to take up and maintain the following  insurance
    with adequate coverage:
      -  Operational   liability   insurance   including  damage  to  persons,
      possessions and assets.  Glass  insurance and  operational  interruption
      insurance are recommended.

    The  insurance  policies  are  to be  signed  at  the  latest  immediately
    following  conclusion  of the rental  contract and shown to the  landlord.
    The tenant is obligated to inform the landlord  immediately  of any change
    in his  operations  and of any  technical or similar  changes  which could
    increase the hazard level.  The tenant is  responsible  for accounting for
    such  changes in any  insurance  agreements  he is  obligated to conclude.
    Failure to provide  or  continue  the  agreed  insurance  despite  warning
    entitles the landlord to give notice with immediate effect.


                      ss. 12 Entering the Rental Property

The  landlord or a person  appointed  by him may enter the rental  property at
reasonable  intervals during operating hours with due advance notice,  for the
purpose  of  examining  conditions.  If  the  landlord  intends  to  sell  the
property or the rental contract has been  terminated or revoked,  the landlord
or an  appointed  person are allowed to enter the rented rooms with the person
interested  in renting or  purchasing.  The tenant must ensure that the rented
facilities  can  also  be  accessed  during  extended  absence  (for  example,
company  holidays)  in order to permit the  landlord to exercise his rights as
landlord.


                          ss. 13 Subletting/Conversion

1.    Subletting  must  be  approved  by the  landlord,  which  approval  only
   applies  to each  single  case of  subletting  and  may be  revoked  by the
   landlord for important  reasons.  If the tenant continues to sublet without
   approval  despite  warning,  the  landlord is  entitled  to give  immediate
   notice of rental contract with immediate effect.

2.    In the  case of  change  of  company  proprietor  or  legal  form of the
   tenant,  all rights and  obligations  are  transferred  to the new  company
   proprietor of the new legal form.







                     ss. 14 Termination of Rental Contract

1.    The  rental  property  is to be  completely  vacated  at the  end of the
    rental  period and restored to its original  state at contract  begin.  Of
    special  importance  are the  constructional  alterations  which are to be
    dismantled,   added  installations   removed,  and  interior  redecoration
    carried out, irrespective of issued approval by the landlord.

2.    The  landlord is entitled  to adopt and  reimburse  the tenant at a fair
    price any installations,  facilities and constructional  alterations added
    by the tenant.

3.    The  landlord  has made  significant  investments  to the benefit of the
tenant at begin of the contract period.  The total planned  investment  volume
for the  rental  property  amounts to EURO 3 054  000.00,  the  proportion  of
expenditures  to the benefit of the tenant  amounts to EURO 706  000.00.  This
proportional  sum  capitalises  over 10 years to EURO  1.264.000,00,  per year
EURO  126.400,00.  If the  rental  contract  is  terminated  before a  10-year
period  of  time,  the  tenant  pays  compensation  to the  landlord  for  the
investments  made in  relation to and for the tenant in the amount of EURO 706
000.00,  as  follows:  For the number of years for which the option  according
to ss.2  subsection 2 was not made use of, a  compensation  payment  becomes due
in the amount of EURO 126 000.00  multiplied by the number of years  involved.
The  amount of EURO  126.000,00  is based on the above  mentioned  capitalised
investment  sum of  EURO  1.264.000,00  divided  by 10  years.  The  following
compensation payments will thus become due:
    End of contract on    31.12.2008:          EURO 632.000,00
                     31.12.2009:          EURO 504.000,00
                     31.12.2010:          EURO 378.000,00
                     31.12.2011:          EURO 252.000,00
                     31.12.2012:          EURO 126.000,00

    The  compensation  payment  becomes due on the above mentioned last day of
    the rental  period and as of this point in time  interest  of at least the
    legal  interest rate according to ss. 288 subsection 2 BGB (civil code) will
    be charged.

Should the total investment  volume be reduced by more than EURO 50 000.00,
the  compensation  payments are to be reduced as a percentage in accordance with
the shortfall in relation to the total investment volume (for example (euro) 100
000.00 / (euro) 3 054 000.00 = 3.27 %). In this case the change must be mutually
agreed and specified in writing prior to begin of the rental contract.

                              ss. 15 Miscellaneous

1.    Subsequent  changes and  additions  to this rental  contract  must be in
   written form.  This also applies to partial waiver of the  requirement  for
   written form. .

2.    Should provisions of the contract be ineffective,  remaining  provisions
   are  not  affected.  The  ineffective  provision  is to be  replaced  by an
   effective one closest in meaning to the desired  economic  purpose.  Should
   a provision be missing regarding  circumstances  which should be regulated,
   the parties must agree on a provision which  reasonably  takes into account
   the interests of both parties.

3.    The attachments are elements of this contract.
