For purposes of this Agreement,  a Specified  Individual  shall not be deemed to

Individual  shall be  expected or required to  undertake  any  investigation  or

11.5     KNOWLEDGE OF BREACH.

For  purposes of this  Section 11,  Celerity-Nevada  shall not be deemed to have

means  of a  diligent  investigation),  on or  prior to the  Closing  Date,  any
knowledge  of the breach of, or of any facts or  circumstances  constituting  or

11.6     NO IMPLIED REPRESENTATIONS.

party a written notice (a "Claim Notice") setting forth:

(a) the specific  representation  and warranty  alleged to have been breached by
such other party;

(b) a detailed  description of the facts and,  circumstances  giving rise to the
alleged breach of such representation and warranty; and

(c) a detailed description of, and a reasonable estimate of the total amount of,
the Damages  actually  incurred or expected to be incurred by the  Claimant as a
direct result of such alleged breach.

Notwithstanding  anything to the contrary  contained in this  Agreement,  Escent
shall not be permitted to deliver any Claim Notice to Celerity-Nevada (and shall
not be  entitled  to  assert  any  indemnification  claim set forth in any Claim
Notice) unless:

         (i) the indemnification claim set forth in such Claim Notice shall have
arisen  from a bona fide  lawsuit or other bona fide legal  proceeding  that was
instituted by a third party  against  Escent prior to the delivery of such Claim
Notice to Celerity-Nevada; or

         (ii) Escent shall have  demonstrated  to  Celerity-Nevada's  reasonable
satisfaction, before the delivery of such Claim Notice to Celerity-Nevada,  that
Escent has theretofore  actually incurred substantial Damages as a direct result
of the alleged breach described in such Claim Notice.

Any Claim Notice that is delivered to  Celerity-Nevada  in  contravention of the
prohibition set forth in the preceding sentence shall not be deemed to have been
duly delivered and shall be of no force or effect.

11.8     DEFENSE OF THIRD PARTY ACTIONS.

If either party hereto (the  "Indemnitee")  receives notice or otherwise obtains
knowledge  of any  Matter  or any  threatened  Matter  that may give  rise to an
indemnification claim against the other party hereto (the "Indemnifying Party"),
then the Indemnitee shall promptly  deliver to the Indemnifying  Party a written
notice describing such Matter in reasonable  detail. The timely delivery of such
written notice by the Indemnitee to the Indemnifying  Party shall be a condition
precedent  to any  liability  on the part of the  Indemnifying  Party under this
Section 11 with respect to such Matter.  The  Indemnifying  Party shall have the
right,  at its  option,  to assume the  defense of any such  Matter with its own
counsel.  If the  Indemnifying  Party  elects to assume the  defense of any such
Matter, then:

(a)  notwithstanding  anything to the contrary contained in this Agreement,  the
Indemnifying  Party  shall not be  required to pay or  otherwise  indemnify  the
Indemnitee  against any attorneys' fees or other expenses  incurred on behalf of
the Indemnitee in connection with such Matter following the Indemnifying Party's
election to assume the defense of such Matter;

(b) the  Indemnitee  shall make available to the  Indemnifying  Party all books,
records and other  documents and materials that are under the direct or indirect
control of the  Indemnitee or any of the  Indemnitee's  Associates  and that the
Indemnifying  Party  considers  necessary or  desirable  for the defense of such
Matter;

(c) the  Indemnitee  shall execute such documents and take such other actions as
the  Indemnifying  Party may reasonably  request for the purpose of facilitating
the defense of, or any  settlement,  compromise or adjustment  relating to, such
Matter;

(d) the Indemnitee  shall otherwise  fully cooperate as reasonably  requested by
the Indemnifying Party in the defense of such Matter;

(e) the Indemnitee shall not admit any liability with respect to such Matter;

(f) the Indemnifying  Party shall have the exclusive right to settle,  adjust or
compromise such Matter,  on such terms as it may deem  appropriate,  without the
consent or approval of the Indemnitee or any other Person.

If the Indemnifying Party elects not to assume the defense of such Matter,  then
the  Indemnitee  shall  proceed  diligently  to  defend  such  Matter  with  the
assistance of counsel satisfactory to the indemnifying Party; provided, however,
that the Indemnitee shall not settle, adjust or compromise such Matter, or admit
any liability with respect to such Matter,  without the prior written consent of
the Indemnifying Party.

11.9     SUBROGATION.

to make any indemnification  payment to the other party hereto (the "Indemnified
Party"),  the Indemnitor shall be entitled to exercise,  and shall be subrogated
to,  any,  rights  and  remedies  (including  rights  of  indemnity,  rights  of
contribution and other rights of recovery) that the Indemnified  Party or any of
the  Indemnified  Party's  Associates  may have  against  any other  Person with
respect to any Damages,  circumstances  or Matter to which such  indemnification
payment is directly or indirectly  related.  The Indemnified  Party shall permit
the  Indemnitor  to use the name of the  Indemnified  Party and the names of the
Indemnified  Party's Associates in any transaction or in any proceeding or other
Matter involving any of such rights or remedies, and the Indemnified Party shall

subrogation hereunder.
