June 1,  1999 and  shall  end,  unless  sooner  terminated  as  provided  in the
Overleases, on September 29, 2000.

       3. Intentionally Deleted.

       4. Services.

         4.1. Electric.  Sub-Subtenant  shall pay $1.50 per rentable square foot
per annum as its  proportionate  share of tenant electric  charges as additional
rent on a  monthly  basis  at the  rate of  $1,648.13.  Sub-Subtenant  will  pay
directly to Landlord any additional  expenses  attributable to the Sub-Subleased
Premises  incurred  for uses of services  outside the normal  Building  Standard
Operation Hours.

         4.2  Additional  Services.  Sub-Subtenant  shall  pay  directly  to the
Landlord any additional  expenses  attributable  to the  Sub-Subleased  Premises
incurred for use of additional Landlord services.

       5.  Rent.  Sub-Subtenant  shall  pay base  rent  during  the Term of this
Sub-Sublease   in  the  amount  of  $18.00  per  rentable  square  foot  of  the
Sub-Subleased  Premises or $237,330.00  annually,  payable monthly in advance on
the first day of each month in equally monthly  installments  of $19,777.50.  In
the event that the Term of this Sub-Sublease  shall begin or end on a date which
is not the first day of a month,  base rent shall be  prorated  as of such date.
Following the complete  execution of this  Sub-Sublease by the parties and prior
to the Commencement Date,  Sub-Subtenant  shall deliver to  Sub-Sublandlord  the
first month's base rent in the amount of $19,777.50. In addition,  Sub-Subtenant
shall be responsible for all telephone  charges  incurred in connection with the
Sub-Subleased  Premises during the Term of this  Sub-Sublease  and shall arrange
with the supplier of the same to have charges directly billed to Sub-Subtenant.

       Following the complete  execution of this Sub-Sublease by the parties and
prior to the Commencement Date,  Sub-Subtenant  shall pay the sum of $79,110.00,
determined under Section 6 below to the Sub-Sublandlord,  which shall be held as
a security deposit  ("Security  Deposit").  Provided that  Sub-Subtenant has not
defaulted in the payment of base rent or in any other of its  obligations  under
this  Sub-Sublease  beyond  applicable  notice and cure  periods,  the  Security
Deposit  shall be  applied  to the rent due for the last four (4)  months of the
Term, subject to the terms specified in Paragraph 6 below.

       6.  Security   Deposit.   Following   the  complete   execution  of  this
Sub-Sublease  by the parties and prior to the  Commencement  Date,  as stated in
Section 5 of this Agreement,  Sub-Subtenant shall deposit with Sub-Sublandlord a
sum equal to four (4) months of base rent, equal to $79,110.00,  as security for
the Sub-Subtenant's  faithful  performance of all of the terms and conditions of
this  Sub-Sublease  including  the  obligation  to pay rent.  For so long as the
Security Deposit has not been repaid by  Sub-Sublandlord or applied to base rent
pursuant to Section 5 of this Agreement,  it shall constitute an account payable
by  Sub-Sublandlord   to  Sub-Subtenant   within  thirty  (30)  days  after  the
termination  of this  Sub-Sublease  to the  extent,  if any,  that the  Security

                                     - 2 -

<PAGE>

Deposit has not been applied by  Sub-Sublandlord  as  hereinafter  provided.  If
Sub-Subtenant  shall default  beyond any  applicable  notice and cure periods as
defined  herein  with  respect  to any term and  condition  hereunder,  then the
Security  Deposit or any part  hereof may be  applied  by  Sub-Sublandlord  (but
Sub-Sublandlord shall not be obligated to do so) to the actual damages sustained
by Sub-Sublandlord by reason thereof.  No such application shall be construed as
an agreement to limit the amount of Sub-Sublandlord's  claim, nor as a waiver of
any damage,  nor as a release of any  indebtedness,  and  Sub-Sublandlord  shall
retain its claims against Sub-Subtenant to the extent not recovered in full from
the Security Deposit.  If Sub-Sublandlord  has so applied all or any part of the
Security Deposit,  Sub-Sublandlord shall have the right (but not the obligation)
at any time thereafter to demand that Sub-Subtenant pay to Sub-Sublandlord a sum
equal to the  amount  so  applied  so that  Sub-Sublandlord  will  always  be in
possession of a sum equal to the amount of the Security  Deposit.  Sub-Subtenant
shall make each such remittance within thirty (30) days following such demand by
Sub-Sublandlord.  Said  remittance  shall  thereupon  constitute  a part  of the
Security  Deposit  subject to the terms and  provisions  hereof.  The failure of
Sub-Subtenant to make any such requested  remittance within such thirty (30) day
period,  and  after  applicable  notice  and  cure  period,  may be  treated  by
Sub-Sublandlord as a failure by Sub-Subtenant to make timely payment of rent and
as an event of default.

       7.  Use.  Sub-Subtenant  covenants  and  agrees  to use the  Premises  in
accordance  with the  provision of the  Overleases  and for no other purpose and
otherwise in accordance with the terms and conditions of the Overleases and this
Sub-Sublease.

       8. Overleases. As appllied to this Sub-Sublease, the words "Landlord" and
"Tenant"  as  used  in  the  Master  Lease,  and  the  words  "Sublandlord"  and
"Subtenant"  as used in the  Master  Sublease,  shall  be  deemed  to  refer  to
Sub-Sublandlord  and Sub-Subtenant  hereunder,  respectively.  Sub-Subtenant and
this  Sub-Sublease  shall be  subject in all  respects  to the terms of, and the
rights of the Overlandlords under, the Overleases. Except as otherwise expressly
provided in Section 8 hereof, the covenants,  agreements,  terms, provisions and
conditions  of the  Overleases  insofar  as  they  relate  to the  Sub-Subleased
Premises  and  insofar  as they  are not  inconsistent  with  the  terms of this
Sub-Sublease  are made a part of and incorporated  into this  Sub-Sublease as if
recited herein in full, and the rights and obligations of the  Overlandlords and
the tenants under the Overleases  shall be deemed the rights and  obligations of
Sub-Sublandlord and Sub-Subtenant  respectively  hererunder and shall be binding
upon and inure to the benefit of Sub-Sublandlord and Sub-Subtenant respectively.
As between the parties hereto only, in the event of a conflict between the terms
of the  Overleases  and  the  terms  of this  Sub-Sublease,  the  terms  of this
Sub-Sublease shall control.

       9.  Operating  Expenses/Real  Estate Taxes.  This is a "gross"  sublease.
Sub-Subtenant shall have no obligation pursuant to Article 7 of the Master Lease
or under paragraph 9 of the Master Sublease,  to pay  Sub-Sublandlord  operating
expenses or real estate taxes.

       10. Overlandlords' Performance Under Overleases.

         10.1 Sub-Subtenant recognizes that Sub-Sublandlord is not in a position
to render many of the services or to perform many of the obligations required of
Sub-Sublandlord  by the terms of this Sub-Sublease.  Therefore,  notwithstanding
anything to the contrary  contained in this Sub-Sublease,  Sub-Subtenant  agrees
that performance by Sub-Sublandlord of its obligations hereunder are conditional
upon due performance by the Overlandlords of its corresponding obligations under
the Overleases and Sub-Sublandlord  shall not be liable to Sub-Subtenant for any
default of the Overlandlords under the Overleases.  Sub-Subtenant shall not have
any claim against  Sub-Sublandlord  by reason of the  Overlandlords'  failure or
refusal to comply  with any of the  provisions  of the  Overleases  unless  such
failure or refusal is a result of Sub-Sublandlord's  act or failure to act. This

                                     - 3 -

<PAGE>

Sub-Sublease  shall  remain  in  full  force  and  effect   notwithstanding  the
Overlandlords'  failure  or  refusal to comply  with any such  provision  of the
Overleases  and  Sub-Subtenant  shall pay the base  rent and all  other  charges
provided  for herein  without any  abatement,  deduction  or setoff  whatsoever.
Notwithstanding  the  foregoing,  if  Overlandlords  default  in  any  of  their
obligations under the Overleases, Sub-Subtenant shall be entitled to participate
with  Sub-Sublandlord  in  any  action  undertaken  by  Sub-Sublandlord  in  the
enforcement   of   Sub-Sublandlord's    rights   against    Overlandlords.    If
Sub-Sublandlord  elects not to take action,  whether  legal action or otherwise,
for  the  enforcement  of   Sub-Sublandlord's   rights  against   Overlandlords,
Sub-Subtenant  shall have the right to take such action in its own name and, for
that purpose and only to such extent,  all the rights of  Sub-Sublandlord  under
the  Overleases  with  respect to the  Sub-Subleased  Premises  shall be and are
hereby conferred upon and assigned to  Sub-Subtenant,  and  Sub-Subtenant  shall
protect,  defend,  indemnify and hold Sub-Sublandlord  harmless from all claims,
costs and liabilities,  including attorney' fees and costs, arising out of or in
connection with any such action by  Sub-Subtenant.  Sub-Subtenant  covenants and
warrants that it fully  understands and agrees to be subject to and abide by all
of  the  covenants,   agreements,   terms,  provisions  and  conditions  of  the
Overleases,   except  as  modified  herein.   Furthermore,   Sub-Subtenant   and
Sub-Sublandlord further covenant not to take any action or do or perform any act
or fail to perform any act which would result in the failure or breach of any of
the covenants,  agreements, terms, provisions or conditions of the Overleases on
the part of the tenants thereunder.

         10.2 Whenever the consents of the  Overlandlords  shall be required by,
or Overlandlords  shall fail to perform their obligations under, the Overleases,
Sub-Sublandlord   agrees  to  use  its  good  faith   efforts   to  obtain,   at
Sub-Subtenant's  sole cost and expense,  such  consents  and/or  performance  on
behalf of Sub-Subtenant.

         10.3  Sub-Sublandlord  represents  and warrants to and  covenants  with
Sub-Subtenant  that  (a)  the  Overleases  is in  full  force  and  effect,  (b)
Sub-Subtenant   has  and  shall  have  no   obligations   with  respect  to  the
Sub-Subleased  Premises with respect to tenant  restoration of alterations  made
prior to the commencement date of the Term of this  Sub-Sublease  (including the
demising wall to be constructed by  Sub-Sublandlord),  the correction of damage,
failure  to make  repairs or other  conditions  relating  thereto,  or any other
obligations with respect thereto arising prior to the  commencement  date of the
Term of this  Sub-Sublease,  and (c) except with  respect to a dispute  with the
Overlandlords  concerning the payment of certain unbilled utility charges, there
are no outstanding  notices,  claims or demands from the  Overlandlords,  nor is
there any  state of facts  which  could  give  rise to such  notices,  claims or
demands,  relating  to any  breach or alleged  breach of any tenant  obligations
under the Overleases.

         10.4  Sub-Sublandlord  covenants  that  Sub-Subtenant  shall have quiet
enjoyment of the Sub-Subleased Premises during the Term, including,  despite the
provisions of the Overleases  (including  the Master Lease rules),  (a) 24-hour,
7-day  per week  access  to the  Sub-Subleased  Premises,  and (b) the  right to
maintain a kitchenette with refrigerator and microwave.
