notwithstanding  anything  contained herein to the contrary,  the Term shall not
extend  beyond the  original  term of the Master  Lease and except as  otherwise

     3. RENT.  Commencing on the Commencement  Date and on the first day of each
month thereafter  during the Term,  Sublessee shall pay to Sublessor rent in the
amount of $284,150.00 ($25.00 per rentable square foot) annually payable without

its use of the  Premises,  except  as  otherwise  set  forth  in this  Sublease.
Sublessee shall also be responsible for Sublessee's pro rata share of the amount
by which the  Operating  Expenses (as that term is defined in the Master  Lease)
relating to the Premises  exceed

Taxes over the fiscal year 2005.  Subject to the  provisions  of paragraph 16 of
this Sublease,  the parties hereto agree that all charges billed by the Landlord

     4. MASTER LEASE.  Subject to all the terms,  covenants and  conditions  set
forth  in this  Sublease  including  the  Sublessor's  obligation  to  reimburse
Landlord for Operating Expenses,  Sublessee agrees to, assumes and shall perform
and  observe  all the  terms  and  conditions  to be  performed  on the  part of
Sublessor (as Tenant) with respect to the Premises pursuant to the Master Lease,
which  arise and  accrue  during  the  Sublease  Term.  During  the Term of this
Sublease,  Sublessee agrees not to do or omit to do (where Sublessee has a legal
duty to act) anything which would cause  Sublessor to be in breach of the Master
Lease, as incorporated  herein.  Sublessee  acknowledges  that it has received a
complete and correct copy of the Master Lease and further  acknowledges that its
duly  authorized  agent  has read and has full  knowledge  of all of the  terms,
covenants,  conditions, rules and regulations, if any, of the Master Lease. This
Sublease  is and shall be at all times  subject  and  subordinate  to the Master
Lease,  and the terms and  conditions  of the Master  Lease shall be  considered
incorporated into this Sublease,  as set forth in this Section, and in the event
there is any  conflict  between the terms of this  Sublease and the Master Lease
with respect to obligations owed by Sublessor or Sublessee to Landlord or to the
Landlord's  rights,  (except with respect to Base Rent, Rent,  Operating Expense
Base Year, Tax Base Year, pro rata share,  Commencement Date, Term, and Security
Deposit - in which case the terms of the  Sublease  shall  control) the terms of
the Master Lease shall govern. Wherever in the Master Lease the word "Tenant" is
used, it shall mean the "Sublessee" herein, and wherever in the Master Lease the
word "Landlord" is used, it shall mean the "Sublessor"  herein, and wherever the
word  "Premises" is used, it shall mean the Premises  subleased  hereunder.  The
following  provisions  of the Master Lease shall not be  incorporated  into this
Sublease:  the last sentence of Article 17;  Article 32;  Article 34 and Article
39.

     Anything  contained in this Sublease to the contrary  notwithstanding,  the
existence of this  Sublease is dependent and  conditioned  upon the existence of
the Master Lease,  and in the event of the  cancellation  or  termination of the
Master Lease for any reason, this Sublease shall thereupon be terminated without
the need for  further  action and (except for any  cancellation  or  termination
caused by a  default  of  Sublessor,  as Tenant  under  the  Master  Lease or as
Sublessor under this Sublease,  or any  cancellation or termination  voluntarily
entered into by Sublessor)  without liability to Sublessor.  If Sublessee is not
in default under the terms and conditions  hereof, any such termination shall be
without  liability  between  Sublessor and Sublessee,  except for such liability
theretofore  accruing or as otherwise provided herein;  however, if Sublessee is
in default, the provisions hereof including those of default shall control as to
Sublessee's liability. Sublessor hereby covenants that (a) it shall not agree to
any termination,  cancellation, or other modification or amendment of the Master
Lease that might  adversely  affect the rights of Sublessee under this Sublease,
(b) that  Sublessor  shall  promptly  perform all of its  obligations  under the
Master Lease which are not  otherwise  to be  performed by Sublessee  under this
Sublease  and (c) that it shall  promptly  forward  to  Sublessee  copies of all
default notices and operating expense and tax statements received from Landlord.



     Notwithstanding  the  foregoing  or anything  else in this  Sublease to the
contrary,  Sublessee  shall  have no  obligation  to (i)  cure  any  default  of
Sublessor under the Master Lease; (ii) perform any obligation of Sublessor under
the Master  Lease that arose prior to the  Commencement  Date;  (iii) repair any
damage to the Premises caused by Sublessor; (iv) indemnify Sublessor or Landlord
with  respect  to  any  act,  omission,  negligence  or  willful  misconduct  of
Sublessor,  or its agents,  employees or contractors;  (v) remove any Alteration
Work or Lines  installed in the Premises prior to the  Commencement  Date of the
Sublease;  (vi) pay for any  overtime  utilities  for which  Sublessor is liable
under the Master Lease unless such  utilities  have been requested by Sublessee;
and (vii) bring the Premises into  compliance  with any laws with which the same
do not  comply as of the  Commencement  Date  except  if  caused by  Sublessee's
particular use.

     5. SUBLEASE AND ASSIGNMENT.  Except for those transactions  permitted under
the Master Lease,  Sublessee shall not, either  voluntarily,  or by operation of
law, sell, hypothecate, assign or transfer this Sublease, or sublet the Premises
or any part  thereof,  or permit the Premises or any part thereof to be occupied
by anyone  other than  Sublessee  or  Sublessee's  employees  without  the prior
written  consent of  Sublessor  in each  instance,  which  consent  shall not be
unreasonably  withheld,  conditioned  or delayed  for more than 10 days.  In the
event  Sublessee  sublets or assigns any part of the Premises as set forth above
and receives rent in excess of $25.00 per rentable square foot ("Excess  Rent"),
then any Excess Rent shall be  immediately  paid to  Sublessor  upon  receipt by
Sublessee.  Sublessor  shall be  notified in writing by  Sublessee  of any sale,
assignment, mortgage transfer, or subletting or other transfer of this Sublease,
whether or not Sublessor's consent is required. Any sale,  assignment,  mortgage
transfer,  or  subletting  or other  transfer of this  Sublease  which is not in
compliance  with the  provisions of this  paragraph 5 shall be null and void and
shall,  at the option of  Sublessor,  terminate  this  Sublease.  The consent by
Sublessor to any sale,  assignment,  mortgage  transfer,  or subletting or other
transfer:  (i) shall not be construed as relieving  Sublessee from obtaining the
express  written  consent of Sublessor to any further  assignment or subletting;
and (ii) shall not release Sublessee from any liability or obligation  hereunder
whether or not then accrued.

     6.  NOTICES.  Any  notice  required  or  permitted  to be given  under this
Sublease shall be given in person (with written  acknowledgement of receipt), by

upon the consent of Landlord

     23.  SECURITY  DEPOSIT.  Sublessee shall deposit with Sublessor a letter of
credit  issued by a banking  institution  of sufficient  financial  standing (as
Sublessor  shall  reasonably  determine)  having an office in Newton or  Boston,
Massachusetts, or Kansas City, Missouri, against which such letter of credit may
be drawn in the amount of Two Hundred Forty Thousand Dollars ($240,000.00) (such
amount, as the same may be reduced in accordance with the provisions hereof, the
"SECURITY  DEPOSIT").  The letter of credit shall be unconditional,  irrevocable
and in favor of Sublessor,  its successors or assigns, and shall provide that it
may be drawn upon "at sight" upon  presentation  by  Sublessor  to the issuer of
only a  statement  certified  by  Sublessor  to the  effect  that a  default  by
Sublessee has occurred  under its Sublease with Sublessor and that Sublessee has
failed to cure such default within the applicable  period, if any, of notice and
grace, or that Sublessor is otherwise  entitled to draw  thereunder  pursuant to
the terms and  conditions of this  Sublease.  The letter of credit shall provide
that it shall remain in force for a period  beginning on the  Commencement  Date
and ending  January 31,  2011,  or for a lesser  period  provided  any letter of
credit expiring prior to January 31, 2011 shall be replaced not later than sixty
(60)  days  prior to its  expiration  by a letter  of credit on all of the terms
otherwise  required  hereunder and the failure to timely  replace such letter of
credit shall be a default with respect to which  Sublessor  shall have the right
to draw the full  amount of the  letter of credit  and retain the same as a cash
security  deposit.  Provided that Sublessee is not in default  hereunder  beyond
applicable  notice and cure periods,  and provided  that  Sublessee has provided
Sublessor  with  audited  financial   statements  prepared  in  accordance  with
accounting  principals  generally accepted in the United States of America which
provide  evidence that the Sublessee has positive net income for the most recent
fiscal year, then during each 12 month period in the Term and within thirty (30)
days of providing such audited financial statements, the amount of the letter of
credit  shall  reduce by twenty  percent  (20%)  from the  preceding  year.  The
Security  Deposit  shall serve as security  for the  prompt,  full and  faithful
performance by Sublessee of the terms and  provisions of this  Sublease.  In the
event  that  Sublessee  is in  default  hereunder  and fails to cure  within any
applicable time period under this Sublease,  or in the event that Sublessee owes
any amounts to Sublessor upon the expiration of this Sublease, Sublessor may use
or apply  the  whole or any part of the  Security  Deposit  for the  payment  of
Sublessee's  obligations  hereunder.  The  use or  application  of the  Security
Deposit or any portion  thereof shall not prevent  Sublessor from exercising any
other  right or  remedy  provided  hereunder  or under  any law and shall not be
construed as liquidated damages. In the event the Security Deposit is reduced by
such use or application,  Sublessee shall deposit with Sublessor within ten (10)
days after  written  notice a new letter of credit  (supplementing  the existing
partially  drawn letter of credit which Sublessor shall retain if Sublessor drew
less than the full amount drawable  thereunder) in the amount drawn by Sublessor
under the existing  letter of credit and otherwise  complying with all terms and
conditions  of the  letter of credit  hereunder.  Any  remaining  portion of the
letter of credit (as reduced by any amount drawn thereon  pursuant hereto) shall
be returned to Sublessee within thirty (30) days after Sublessee has vacated the
Premises and complied with all the terms of this Sublease.



     IN WITNESS  WHEREOF,  the parties  hereto have executed this Sublease as of
the day and year first written above.
