the Acquired Assets, each of Seller and Buyer shall present a statement to the
other setting forth the amount of reimbursement to which each is entitled under
this Section together with such supporting evidence as is reasonably necessary
to calculate the proration amount. The proration amount shall be paid by the
party owing it to the other within 30 days after delivery of such statement. In
the event that either Seller or Buyer shall make any payment for which it is
entitled to reimbursement under this Section, the other party shall make such
reimbursement promptly but in no event later than ten (10) days after the
presentation of a statement setting forth the amount or reimbursement to which
the presenting party is entitled along with such supporting evidence as is
reasonably necessary to calculate the amount of reimbursement.

information and assistance relating to the Acquired Assets (including, without
limitation, access to books and records) as is reasonably necessary for the
filing of all Tax Returns, the making of any election relating to Taxes, the
preparation for any audit by any taxing authority, and the prosecution or
defense of any claim, suit or proceeding relating to any Tax. Buyer and Seller
shall retain all books and records with respect to Taxes pertaining to the
Acquired Assets for a period of at least six (6) years following the Closing
Date. At the end of such period, each party shall provide the other with at
least thirty (30) days prior written notice before destroying any such books and
records, during which period the party receiving such notice can elect to take
possession, at its own expense, of such books and records.  Seller and Buyer
shall cooperate with each other in the conduct of any audit or other proceeding
relating to Taxes involving the Acquired Assets.  If either party becomes aware
of any pending or threatened assessment, official inquiry, examination or
proceeding that could result in an official determination with respect to Taxes
due or payable the responsibility for which rests with the other party hereto,
such party shall promptly so notify the other party in writing.

     Section 10.4.  Indemnification Procedures.  (a) If any indemnified party
                    ---------------------------
receives notice of the assertion of any Third Party Claim with respect to which
an indemnifying party is obligated under this Agreement to provide
indemnification, such indemnified party shall give such indemnifying party
written notice thereof (together with a copy of such Third Party Claim, process
or other legal pleading) promptly after becoming aware of such Third Party
Claim; provided, however, that the failure of any indemnified party to give
notice as provided in this Section 10.4 shall not relieve any indemnifying party
of its obligations under this Section 10.4, except to the extent that such
indemnifying party is actually prejudiced by such failure to give notice. Such
notice shall describe such Third Party Claim in reasonable detail.

     (b)  An indemnifying party, at such indemnifying party's own expense and
through counsel chosen by such indemnifying party (which counsel shall be
reasonably acceptable to the indemnified party), may elect to defend any Third
Party Claim. If an indemnifying party elects to defend a Third Party Claim,
then, within ten (10) business days after receiving notice of such Third Party
Claim (or sooner, if the nature of such Third Party claim so requires), such
indemnifying party shall notify the indemnified party of its intent to do so,
and such indemnified party shall cooperate in the defense of such Third Party
Claim (and pending such notice and assumption of defense, an indemnified party
may take such steps to defend against such Third-Party Claim as, in such
indemnified party's good-faith judgment, are appropriate to protect its
interests). Such indemnifying party shall pay such indemnified party's
reasonable out-of-pocket expenses incurred in connection with such cooperation.
Such indemnifying party shall keep the indemnified party reasonably informed as
to the status of the defense of such Third Party Claim. After notice from an
indemnifying party to an indemnified party of its election to assume the defense
of a Third Party Claim, such indemnifying party shall not be liable to such
indemnified party under this Section 10.4 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than those expenses referred to in the preceding sentence;
provided, however, that such indemnified party shall have the right to employ
one law firm as counsel, together with a separate local law firm in each
applicable jurisdiction ("Separate Counsel"), to represent such indemnified
party in any action or group of related actions (which firm or firms shall be
reasonably acceptable to the indemnifying party) if, in such indemnified party's
reasonable judgment at any time, either a conflict of interest between such
indemnified party and such indemnifying party exists in respect of such claim,
or there may be defenses available to such indemnified party which are different
from or in addition to those available to such indemnifying party and the
representation of both parties by the same

                                      -24-
<PAGE>

counsel would be inappropriate, and in that event (i) the reasonable fees and
expenses of such Separate Counsel shall be paid by such indemnifying party (it
being understood, however, that the indemnifying party shall not be liable for
the expenses of more than one Separate Counsel (excluding local counsel) with
respect to any Third Party Claim (even if against multiple indemnified
parties)), and (ii) each of such indemnifying party and such indemnified party
shall have the right to conduct its own defense in respect of such claim. If an
indemnifying party elects not to defend against a Third Party Claim, or fails to
notify an indemnified party of its election as provided in this Section 10.4
within the period of ten (10) business days described above, the indemnified
party may defend, compromise, and settle such Third Party Claim and shall be
entitled to indemnification hereunder (to the extent permitted hereunder);
provided, however, that no such indemnified party may compromise or settle any
such Third Party claim without the prior written consent of the indemnifying
party, which consent shall not be unreasonably withheld or delayed.
Notwithstanding the foregoing, the indemnifying party shall not, without the
prior written consent of the indemnified party, (i) settle or compromise any
Third Party Claim or consent to the entry of any judgment which does not include
as an unconditional term thereof the delivery by the claimant or plaintiff to
the indemnified party of a written release from all liability in respect of such
Third-Party Claim, or (ii) settle or compromise any Third Party Claim in any
manner that would reasonably be expected to have a material adverse effect on
the indemnified party.

     Section 10.5.  Certain Limitations.  (a) The amount of any Covered
                    -------------------
Liabilities for which indemnification is provided. under this Agreement shall be
net of any amounts actually recovered by the indemnified party from third
parties (including amounts actually recovered under insurance policies) with
respect to such Covered Liabilities.  Any indemnifying party hereunder shall be
subrogated to the rights of the indemnified party upon payment in full of the
amount of the relevant indemnifiable loss.  An insurer who would otherwise be
obligated to pay any claim shall not be relieved of the responsibility with
respect thereto or, solely by virtue of the indemnification provision hereof,
have any subrogation rights with respect thereto.  If any indemnified party
recovers an amount from a third party in respect of an indemnifiable loss for
which indemnification is provided in this Agreement after the full amount of
such indemnifiable loss has been paid by an indemnifying party or after an
indemnifying party has made a partial payment of such indemnifiable loss and the
amount received from the third party exceeds the remaining unpaid balance of
such indemnifiable loss, then the indemnified party shall promptly remit to the
indemnifying party the excess of (A) the sum of the amount theretofore paid by
such indemnifying party in respect of such indemnifiable loss plus the amount
received from the third party in respect thereof, less (B) the full amount of
such Covered Liabilities.

     (b)  No remedy under this Agreement or at law or in equity shall include,
provide for or permit the payment of multiple, exemplary, punitive or
consequential damages or any equitable equivalent thereof or substitute
therefor, and the burden shall be on the party claiming loss to show actual loss
in the amount claimed.

Section 11.1, written notice thereof shall forthwith be given by the terminating
party to the other party hereto, and this Agreement shall thereupon terminate

shall be abandoned without further action by the parties hereto, except that the
provisions of Sections 5.1(b) and 12.4 shall survive the termination of this

made pursuant to Sections 3.7 and 4.3 shall, to the extent practicable, be
withdrawn from the agency or other persons to which they were made.
