(ii) any breach or default by EXL of its obligations under this Agreement.

11.3

Survival.  The respective indemnity obligations of the parties set forth in this
Section 11 shall survive the Closing, and may be enforced by the parties and
their successors and assigns following the Closing.

12.

Agreement of the Parties.  This Agreement and the Consulting Services Agreement
represent the entire and integrated agreement of the parties hereto, and
supersede any and all prior agreements between the parties, including without
limitation that certain Letter of Intent between HBS and EXL dated July 19,
2006, which Letter of Intent is hereby terminated as of the Effective Date
hereof.  HBS, HBS Bio, EXL and Luster expressly acknowledge, warrant and
understand that there are no statements, representations, inducements or
agreements made by or between the parties hereto except as expressly set forth
herein in writing.  No amendment, supplement or termination hereof shall be
valid except by way of writing subscribed by the parties hereto.

13.

Attorneys’ Fees.  In connection with any suit or other proceeding (including
without limitation appellate or bankruptcy proceedings) with respect to the
subject matter, interpretation or enforcement of this Agreement, or the right to
indemnification hereunder, the prevailing party (as determined by the court,
agency or other authority before which suit or proceeding is commenced) shall,
in addition to such other relief as may be awarded, be entitled to recover
reasonable attorneys’ fees, expert witness fees, expenses and costs of suit or
investigation as actually incurred.

14.

Assignment.  This Agreement shall not be assignable by any party without the
prior written consent of the other parties, which consent shall not be
unreasonably withheld.  Subject to such consent, the terms, conditions and
covenants of this Agreement shall be binding upon, and inure to the benefit of,
the parties and their respective successors and permitted assigns.  

15.

Notices.  All notices which may be or are required to be given by either party
to the other party hereunder shall be in writing (“Notices”).  All Notices shall
be sufficiently given, made or delivered if personally served.  All Notice shall
also be sufficiently given, made or delivered (i) upon facsimile transmission to
the numbers specified under the party’s signatures so long as such transmission
is completed prior to 5:00 p.m. California time and a confirming copy is sent by
United States mail, (ii) the next business day following deposit with a national
overnight courier service, addressed to the parties at the addresses under their
signatures, or (iii) forty-eight (48) hours following the certified mailing
thereof, postage prepaid, addressed to the parties at the addresses under their
signatures.

16.

Time.  Time is of the essence of this Agreement and every provision hereof.  

 

17.

Uncontrollable Forces.  No party to this Agreement shall be in default under
this Agreement when a failure of performance shall be the result of
uncontrollable forces.  The term “uncontrollable forces” shall mean any cause or
causes beyond the control of a party, including without limitation failure of or
threat of failure of facilities, flood, earthquake, storm, drought, fire,
lightning, or other natural catastrophe, civil disturbance or disobedience,
sabotage, war and/or acts of terrorism, government priorities and restraint by
court order or public authority, and action or non-action by, or inability to
obtain or maintain in effect, the necessary authorizations or approvals from any
governmental agency or authority, any of which by exercise of due diligence of a
party could not reasonably have been expected to avoid and which by exercise of
due diligence it has been unable to overcome.  Nothing contained in this section
shall be construed as requiring a party to settle any labor dispute in which it
may be involved, or to enter into any contracts or commit to financing
arrangements, which contains conditions or terms which a party determines are
unduly burdensome.

18.

Fees and Expenses.  Each party shall bear and pay all fees, costs and expenses
(including fees and expenses of such party’s legal, accounting, financial and
other advisors) that have been incurred or that are in the future incurred by,
on behalf of or for the benefit of, such party in connection with: (i) the
negotiation, preparation and review of the Letter of Intent; (ii) the
negotiation, preparation and review of this Agreement, including the Exhibits
and Schedules hereto; and (iii) the consummation and performance of the
transactions contemplated hereby; provided, however, that upon the Closing, HBS
shall reimburse EXL for its legal expenses up to an aggregate of $10,000.

19.

Waiver.  No waiver by any party of any of the terms or conditions of this
Agreement or any of such party’s rights under this Agreement shall be effective
unless such waiver is in writing and signed by the party charged with the
waiver.

20.

Exhibits and Schedules.  The Exhibits and Schedules to this Agreement are
incorporated by this reference as if fully set forth herein.

21.

Counterparts.  This Agreement may be executed in two or more counterparts, each
of which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

22.

Independent Counsel; No Presumption.  Each party acknowledges that:  (a) it has
been represented by independent counsel in connection with this Agreement; (b)
it has executed this Agreement with the advice of such counsel; and (c) this
Agreement is the result of negotiations between the parties hereto and the
advice and assistance of their respective counsel.  The fact that this Agreement
was prepared by counsel for one party or the other as a matter of convenience
shall have no import or significance.  Any uncertainty or ambiguity in this
Agreement shall not be construed against either party because its counsel
prepared this Agreement in its final form.

23.

Severability.  If any provision of this Agreement or application thereof to any
person or circumstance shall to any extent be invalid or unenforceable, the
remainder of this Agreement (including the application of such provision to
persons or circumstances other than those to which it is held invalid or
unenforceable) shall not be affected thereby, and each provision of this
Agreement shall be valid and enforced to the fullest extent permitted by law.

24.

Interpretation.  Words used in the singular number shall include the plural, and
vice-versa, and any gender shall be deemed to include every other gender.  The
captions and headings of the Articles and Sections of this Agreement are for
convenience of reference only and shall not be deemed to define or limit the
provisions hereof.  The Recitals stated above are material parts of the
consideration of this Agreement and are incorporated by reference as terms of
this Agreement.

 

25.

Governing Law.  This Agreement shall be governed by and construed in accordance
with the internal laws of the State of California (without giving effect to
principles of conflicts of laws).  Any Proceeding relating to this Agreement or
the enforcement of any provision of this Agreement shall be brought or otherwise
commenced in any state or federal court located in the County of Santa Clara,
California.  Each party expressly and irrevocably consents and submits to the
non-exclusive jurisdiction of each state and federal court located in the County
of Santa Clara, California (and each appellate court located in the State of
California) in connection with any such Proceeding.
