amendment of the terms of the Asset Purchase Agreement or any Ancillary
Agreement or any forebearance as to time or performance or failure by Asuragen
to proceed promptly with respect to the Obligations or this Guaranty; or
b.any change in the corporate existence, structure or ownership of Interpace or
Guarantor, or any insolvency, bankruptcy, reorganization, dissolution,
liquidation, arrangement, assignment for the benefit of creditors or other

Guarantor’s Affiliates, or any other Person to collect payment or enforce
performance of the Obligations or otherwise exhaust any right, power or remedy
under the Asset Purchase Agreement, any Ancillary Agreement or any other
agreement giving rise to any such Obligations to collect payment or enforce
performance of the Obligations before proceeding hereunder; and
b.all suretyship defenses including all defenses based upon any statute or rule
of law that provides that the obligation of a surety must be neither larger in
amount nor in other respects more burdensome than that of the principal.

defenses to the Obligations that Interpace would be entitled to assert against
Asuragen in any action brought by Asuragen against Interpace in respect of the
Obligations.

5.Action Against Guarantor. In the event of a default by Interpace under the
Asset Purchase Agreement or any Ancillary Agreement, Asuragen shall have the

Affiliates or Interpace which Guarantor may acquire by way of subrogation,
reimbursement, exoneration, contribution, indemnity, applicable law or
otherwise, by any payment made under this Guaranty until all of the Obligations
shall have been paid in full and until the earlier of one (1) year after payment
in full or the period during which any payment by Interpace or Guarantor is or

10.Remedy. Guarantor acknowledges and agrees that the rights of Asuragen under
this Guaranty are of a specialized and unique character and that immediate and
irreparable damage will result to Asuragen if Guarantor fails to or refuses to
perform its obligations under this Guaranty and, notwithstanding any election by
Asuragen to claim damages from Guarantor as a result of any such failure or
refusal, Asuragen is, in addition to any other remedies and damages available,
entitled to injunctive or other equitable relief (including specific
performance) in a court of competent jurisdiction to restrain any such failure
or refusal, and Guarantor hereby waives any requirement for Asuragen to post any
bond or other security. No single exercise of the foregoing remedy shall be
deemed to exhaust Asuragen’s right to such remedy, but the right to such remedy
shall continue undiminished and may be exercised from time to time as often as
Asuragen may elect.

11.Severability. If any court holds that any provisions of this Guaranty as
applied to any part or to any circumstances is invalid or unenforceable, such
holding shall in no way affect any other provision of this Guaranty, the
application of such provision in any other circumstances or jurisdictions or the
validity or enforceability of this Guaranty. Asuragen and Guarantor intend this
Guaranty to be enforced as written. If any provision, or part thereof, however,
is held to be unenforceable because of the scope or duration thereof or the area
covered thereby, Asuragen and Guarantor agree that the court making such
determination shall have the power to reduce the scope, duration and/or area of
such provision, and/or to delete specific words or phrases and in its reduced
form such provision shall then be enforceable.

12.No Benefit to Third Parties. The covenants and agreements set forth in this
Guaranty are for the sole benefit of the Asuragen and Guarantor and their
respective successors and permitted assigns, and they shall not be construed as
conferring any rights on any other persons.

--------------------------------------------------------------------------------

13.Amendment. This Guaranty may not be modified, amended, altered or
supplemented except upon the execution and delivery of a written agreement
executed by both parties.

14.Waiver. Any term or condition of this Guaranty may be waived at any time by
the party that is entitled to the benefit thereof, but no such waiver shall be
effective unless set forth in a written instrument duly executed by or on behalf
of the party waiving such term or condition.

15.Construction. Except where the context otherwise requires, wherever used, the
singular includes the plural, the plural the singular, the use of any gender
shall be applicable to all genders and the word “or” is used in the inclusive
sense (and/or). The captions of this Guaranty are for convenience of reference
only and in no way define, describe, extend or limit the scope or intent of this
Guaranty or the intent of any provision contained in this Guaranty. The term
“including” as used herein does not limit the generality of any description
preceding such term. The language of this Guaranty shall be deemed to be the
language mutually chosen by the parties and no rule of strict construction shall
be applied against either party. Unless otherwise specified or where the context
otherwise requires, (a) references in this Guaranty to any Section are
references to such Section of this Guaranty; (b) references in any Section to
any clause are references to such clause of such Section; (c) “hereof,”
“hereto,” “hereby,” “herein” and “hereunder” and words of similar import when
used in this Guaranty refer to this Guaranty as a whole and not to any
particular provision of this Guaranty; (d) references to a person are also to
its permitted successors and assigns; (e) references to a law include any
amendment or modification to such law and any rules or regulations issued
thereunder, in each case, as in effect at the relevant time of reference
thereto; and (f) references to any agreement, instrument or other document in
this Guaranty refer to such agreement, instrument or other document as
originally executed or, if subsequently amended, replaced or supplemented from
time to time, as so amended, replaced or supplemented and in effect at the
relevant time of reference thereto.

16.Governing Law. This Guaranty shall be governed by and construed in accordance
with the Laws of the State of Delaware, excluding any conflicts or choice of law
rule or principle that might otherwise refer construction or interpretation of
this Guaranty to the substantive law of another jurisdiction.

17.Entire Agreement. This Guaranty is a final expression of Guarantor’s
agreement to guarantee the Obligations and is a complete and exclusive statement
of the terms of such agreement, superseding all other agreements, discussions or
understandings with respect to Guarantor’s guarantee of the Obligations.

18.Unsecured and Unsubordinated Obligations. This Guaranty is unsecured and
ranks pari passu with all other unsecured and unsubordinated obligations of
Guarantor.
