R E C I T A L S

 

A. Sublandlord and Subtenant entered into a sublease, dated as of September 14,
2004 (“Sublease”) in which Sublandlord subleased to Subtenant that certain real
property on the fourth floor and the first floor (“Premises”) of the building
located at 675 West Kendall Street, Cambridge, Massachusetts (“Building”); and

 

B.  The Sublease provided in Section 1(b) for the use of approximately 20,000
rentable square feet located on the third floor of the Building and defined in
the Sublease as the “Temporary Premises” from the Commencement Date until three
(3) business days after the delivery of the Sublease Premises to Subtenant with
the Subtenant Improvements having been Substantially Completed at which time
Subtenant was to vacate the Temporary Premises in accordance with the terms of
the Sublease;  and

 

C.  Sublandlord has so delivered the Sublease Premises to Subtenant, but
Subtenant desires to continue on a temporary basis to occupy the Temporary
Premises as well as the Sublease Premises and Sublandlord has agreed to permit
such occupancy by extending the period of such occupancy by Subtenant of the
Temporary Premises on the terms and conditions set forth herein.

OCTOBER 31, 2005 (THE “TEMPORARY PREMISES EXPIRATION DATE”).  THE FIRST SENTENCE
OF SECTION 1(C) IS AMENDED TO ADD IN THE SECOND LINE AFTER THE WORDS “SUBLEASE

IN ADDITION TO ALL RIGHTS AND REMEDIES AVAILABLE TO SUBLANDLORD AT LAW AND IN
EQUITY, SUCH CONTINUED OCCUPANCY SHALL CONSTITUTE HOLDING OVER OF THE TEMPORARY
PREMISES AND SHALL BE GOVERNED BY SECTION 1(H) OF THE SUBLEASE WITH RESPECT TO
THE TEMPORARY PREMISES ONLY (BUT NOT THE SUBLEASE PREMISES).

 

5.                                       DEFINITIONS. UNLESS OTHERWISE SET FORTH
IN THIS AMENDMENT, ALL CAPITALIZED TERMS SHALL HAVE THE SAME MEANING AS SET
FORTH IN THE SUBLEASE.

 

6.                                       EFFECTIVE DATE. THIS AMENDMENT SHALL

AMENDMENT (“EFFECTIVE DATE”).

 

7.                                       RATIFICATION.  THE SUBLEASE, AS AMENDED
HEREBY, IS HEREBY RATIFIED, CONFIRMED AND DEEMED IN FULL FORCE AND EFFECT IN
ACCORDANCE WITH ITS TERMS.  EACH PARTY REPRESENTS TO THE OTHER THAT SUCH PARTY
(A) IS CURRENTLY UNAWARE OF ANY DEFAULT BY THE OTHER PARTY UNDER THE SUBLEASE;
AND (B) HAS FULL POWER AND AUTHORITY TO EXECUTE AND DELIVER THIS AMENDMENT AND
THIS AMENDMENT REPRESENTS A VALID AND BINDING OBLIGATION OF SUCH PARTY
ENFORCEABLE IN ACCORDANCE WITH ITS TERMS.

 

8.                                       MULTIPLE COUNTERPARTS.  THIS AMENDMENT
MAY BE EXECUTED IN MULTIPLE COUNTERPARTS, EACH OF WHICH WHEN SO EXECUTED AND
DELIVERED SHALL BE DEEMED TO BE ORIGINALS AND TOGETHER SHALL CONSTITUTE BUT ONE
AND THE SAME INSTRUMENT.

 

9.                                       NO OFFER.  SUBMISSION OF THIS
INSTRUMENT FOR EXAMINATION AND SIGNATURE BY SUBTENANT DOES NOT CONSTITUTE AN
OFFER TO LEASE OR A RESERVATION OF OR OPTION FOR LEASE, AND THIS INSTRUMENT IS
NOT EFFECTIVE AS A SUBLEASE AMENDMENT OR OTHERWISE UNTIL EXECUTED AND DELIVERED
BY BOTH SUBLANDLORD AND SUBTENANT AND CONSENTED TO BY MASTER LANDLORD.
