indemnify Purchaser, its Affiliates and their respective officers, directors,
employees independent contractors, stockholders, principals, partners, agents,
or representatives (each an "Indemnified Person" and collectively, the
"Indemnified Persons") against, and to hold each Indemnified Person harmless
from, any and all Losses incurred or suffered by any Indemnified Person relating
to or arising out of or in connection with (a) any breach of or any inaccuracy
in any representation or warranty made by Sellers in this Agreement, or (b) any
breach of or failure by any Sellers to perform any of its covenants or
obligations set out or contemplated in this Agreement.

      6.2 Claims. As promptly as is reasonably practicable after becoming aware
of a claim for indemnification under this Agreement, the Indemnified Person
shall promptly give notice to the indemnifying Seller or Sellers ("Indemnifying
Person") of such claim and the amount the Indemnified Person will be entitled to
receive hereunder from the Indemnifying Person; provided that the failure of the
Indemnified Person to promptly give notice shall not relieve the Indemnifying
Person of its obligations except to the extent (if any) that the Indemnifying
Person

                                        6



shall have been prejudiced thereby. If the Indemnifying Person does not object

thereof, the Indemnified Person shall be entitled to recover, on the
thirty-fifth day after such notice was given, from the Indemnifying Person the
amount of such claim, and no later objection by the Indemnifying Person shall be

thirty-fifth day after such notice was given, from the Indemnifying Person the
lesser amount, without prejudice to the Indemnified Person's claim for the
difference. In addition to the amounts recoverable by the Indemnified Person
from the Indemnifying Person pursuant to the foregoing provisions, the
Indemnified Person shall also be entitled to recover from the Indemnifying
Person interest on such amounts at the rate of Two Times Prime from, and

given to, but not including, the date such recovery is actually made by the
Indemnified Person.

Person shall give notice as promptly as is reasonably practicable to the
Indemnifying Person of the assertion of any claim, or the commencement of any
suit, action or proceeding, by any Person not a party hereto (a "Third Party
Claim") in respect of which indemnity may be sought under this Agreement;
provided that the failure of the Indemnified Person to promptly give notice
shall not relieve the Indemnifying Person of its obligations except to the
extent (if any) that the Indemnifying Person shall have been prejudiced thereby.
The Indemnifying Person may, at its own expense, participate in the defense of
any Third Party Claim, suit, action or proceeding (a) upon notice to the
Indemnified Person and (b) upon delivery by the Indemnifying Person to the
Indemnified Person a written agreement that the Indemnified Person is entitled
to indemnification for all Losses arising out of such Third Party Claim, suit,
action or proceeding and that the Indemnifying Person shall be liable for the
entire amount of any Loss, at any time during the course of any such Third Party
Claim, suit, action or proceeding, assume the defense thereof; provided,
however, that (i) the Indemnifying Person's counsel is reasonably satisfactory
to the Indemnified Person, and (ii) the Indemnifying Person shall thereafter
consult with the Indemnified Person upon the Indemnified Person's reasonable
request for such consultation from time to time with respect to such Third Party
Claim, suit, action or proceeding. If the Indemnifying Person assumes such
defense, the Indemnified Person shall have the right (but not the duty) to
participate in the defense thereof and to employ counsel, at its own expense,
separate from the counsel employed by the Indemnifying Person. If, however, the
Indemnified Person reasonably determines in its judgment that representation by
the Indemnifying Person's counsel of both the Indemnifying Person and the
Indemnified Person would present such counsel with a conflict of interest, then
such Indemnified Person may employ separate counsel to represent or defend it in
any such Third Party Claim, action, suit or proceeding and the Indemnifying
Person shall pay all of the fees and disbursements in connection with the
retention of such separate counsel. If the Indemnifying Person fails to promptly
notify the Indemnified Party that the Indemnifying Party desires to defend the
Third Party Claim pursuant, or if the Indemnifying Person gives such notice but
fails to prosecute vigorously and diligently or settle the Third Party Claim,
then the Indemnified Party will have the right to defend, at the sole cost and
expense of the Indemnifying Person, the Third Party Claim by all appropriate
proceedings, which proceedings will be prosecuted by the Indemnifying Person in
good faith or will be settled at the discretion of the Indemnifying Person (with
the consent of the Indemnifying Person, which consent will not be unreasonably
withheld). The Indemnifying Person will have full control of

                                        7



such defense and proceedings, including any compromise or settlement thereof.
Whether or not the Indemnifying Person chooses to defend or prosecute any such
Third Party Claim, suit, action or proceeding, all of the parties hereto shall
cooperate in the defense or prosecution thereof.

      6.4 Settlement or Compromise. Any settlement or compromise made or caused
to be made by the Indemnified Person or the Indemnifying Person, of any claim,
suit, action or proceeding shall also be binding upon the Indemnifying Person or
the Indemnified Person, as the case may be, in the same manner as if a final
judgment or decree had been entered by a court of competent jurisdiction in the
amount of such settlement or compromise thereof; provided, however, that no
obligation, restriction or Loss shall be imposed on the Indemnified Person as a
result of such settlement without its prior written consent. The Indemnified
Person will give the Indemnifying Person at least 30 days' notice of any
proposed settlement or compromise of any Third Party Claim, suit, action or
proceeding it is defending, during which time the Indemnifying Person may reject
such proposed settlement or compromise; provided, however, that from and after
such rejection, the Indemnifying Person shall be obligated to assume the defense
of and full and complete liability and responsibility for such Third Party
Claim, suit, action or proceeding and any and all Losses in connection therewith
in excess of the amount of unindemnifiable Losses which the Indemnified Person
would have been obligated to pay under the proposed settlement or compromise.

      6.5 Failure of Indemnifying Person to Act. In the event that the
Indemnifying Person does not assume the defense of any Third Party Claim, suit,
action or proceeding brought against an Indemnified Person, then any failure of
the Indemnified Person to defend or to participate in the defense of any such
Third Party Claim, suit, action or proceeding or to cause the same to be done,
shall not relieve the Indemnifying Person of any of its obligations under this
Agreement.

      6.6 Tax Character. Sellers and Purchaser agree that any payments pursuant
to this Article VI will be treated for federal and state income tax purposes as
adjustments to the purchase price of the Membership Interest, and that they will
report such payments on all Tax Returns consistently with such characterization.

                                  ARTICLE VII

courts of the United States of America located in the Southern District of New
York, and each party hereby agrees that all suits, actions and proceedings
brought by such party hereunder shall be brought in any such court. Each party
irrevocably waives, to the fullest extent permitted by law, any objection which
it may now or hereafter have to the laying of the venue of any such suit, action
or proceeding brought in any such court, any claim that any such suit, action or
proceeding brought in such a court has been brought in an inconvenient forum and
the right to object, with respect to any such suit, action or proceeding brought
in any such court, that such court does not have jurisdiction over such party or
the other party. In any such suit, action or proceeding, each party waives, to
the fullest extent it may effectively do so, personal service of any summons,
complaint or other process and agrees that the service thereof may be made by
any means permitted by Section 8.15 (other than facsimile transmission). Each
party agrees that a final non-appealable judgment in any such suit, action or
proceeding brought in such a court shall be conclusive and binding.
