(b)                         In addition, in connection with performance of the Services and in connection with the Undertakings, the Provider may incur certain out-of-pocket costs consistent in nature and magnitude with past practice (the “Other Costs”), which shall either be paid directly by the Recipient or reimbursed to the Provider by the Recipient; provided that any Other Costs shall only be payable by ▇▇▇▇▇ Group or SG, as the case may be, in accordance with this Section 4.01 if the Recipient receives from the Provider reasonably detailed data and other documentation sufficient to support the calculation of amounts due to the Provider for such Other Costs; provided further that any Other Costs already included in the Service Charges shall not otherwise be paid or reimbursed by the Recipient pursuant to this paragraph.

(c)                          Notwithstanding anything to the contrary in this Agreement, including the Schedules, in the event that the level of any Service is decreased or increased as provided in Section 10.08, then the Service Charge and Other Costs associated therewith shall be reduced or increased to reflect pro rata the decrease or increase in Services provided.

SECTION 4.02.  Invoices; Payment.  From and after the date of the Cowen IPO, the Provider shall deliver an invoice to the Recipient on a monthly basis (or at such other frequency as is consistent with the basis on which the Service Charges are determined and, if applicable, charged to Subsidiaries of the Provider) in arrears for the Service Charges and any Other Costs due to the Provider under this Agreement.  The Recipient shall pay the amount of such invoice to the Provider in U.S. dollars within thirty (30) days of the date Recipient received such invoice, provided that, to the extent consistent with past practice with respect to Services rendered outside the United States, payments may be made in local currency.

If the Provider’s furnishing of such information does not promptly resolve such dispute, the dispute shall be resolved pursuant to Section 8.01 of this Agreement.

7

to the amount due, interest on such amount at the lesser of (i) SG’s prime rate, plus two percent or (ii) the maximum rate of interest allowed by applicable law, from the date the payment was due through the date of payment.

SECTION 4.04.  Taxes.  (a)  Each Recipient shall pay any and all Taxes (other than taxes imposed on or measured by the Provider’s overall net income (however denominated), and franchise taxes imposed on the Provider (in lieu of net income taxes)) imposed or otherwise incurred in connection with the applicable Provider’s provision of Services, including all sales, use, excise, value-added, services, consumption, and similar Taxes.

(b)                         Each of the Parties agrees that if reasonably requested by another Party, it will cooperate with such other Party to enable the accurate determination of such other Party’s Liability for Taxes and assist such other Party in minimizing its Liability for Taxes to the extent commercially reasonable and legally permissible, in each case, in respect of Taxes, including all sales, use, excise, value-added, services, consumption and similar Taxes, imposed or otherwise incurred in connection with the applicable Provider’s provision of Services.

SECTION 4.05.  No Right to Set-Off.  The Recipient shall pay the full amount of Service Charges and Other Costs incurred by the Provider under this Agreement, and shall not set-off or otherwise withhold any such amount owed to the Provider on account of any obligation owed by the Provider to the Recipient.

(b)                                 In addition to and not in limitation of the rights and obligations set forth in Articles II, III and V, upon the request of the Recipient of a Service, the Provider of such Service will, during the term of this Agreement during which such Provider is providing such Service to the Recipient, cooperate with the Recipient and use its good faith, commercially reasonable efforts to assist the transition of such Service to the Recipient (or Subsidiary of the Recipient or vendor designated by the Recipient) by the Service Termination Date for such Service, except where, in the case of the Services described on Schedules ▇-▇, ▇-▇ and B-1, the Parties have reached a mutually acceptable agreement for the continued provision of such Services by SG to the ▇▇▇▇▇ Group on a stand-alone basis after December 31, 2006.

SECTION 9.02.  Effect of Termination.  Upon termination or expiration of any Service or Undertaking pursuant to this Agreement, the relevant Provider will have no further obligation to provide the terminated Service or expired Undertaking, and the relevant Recipient will have no obligation to pay any future Service Charges or Other Costs relating to any such Service or Undertaking (other than for or in respect of Services or Undertakings provided in accordance with the terms of this Agreement and received by such Recipient prior to such termination).

SECTION 9.03.  Survival.  (a) Article IV (Billing; Taxes), Section 6.01 (Consents), Section 6.02 (Access), Article VII (Indemnification; Limitation on Liability), Article VIII (Dispute Resolution), Section 9.02 (Effect of Termination), Section 9.03 (Survival), and Article X (General Provisions) shall survive the expiration or other termination of this Agreement and remain in full force and effect.

(b)                                 Force Majeure.  No Party hereto shall be deemed in default of this Agreement to the extent that any delay or failure in the performance of its obligations (other than a payment obligation) under this Agreement results from any cause beyond its reasonable control and without its fault or negligence, such as acts of God, acts of Governmental Authority, embargoes,

12

epidemics, war, riots, insurrections, acts of terrorism, fires, explosions, earthquakes, floods, unusually severe weather conditions, labor problems or unavailability of parts, or, in the case of computer systems, any failure in electrical or air conditioning equipment.  Each Party, upon learning of the occurrence of any such force majeure event that would reasonably be expected to result in a delay or failure in the performance of its obligations (other than a payment obligation) under this Agreement, will promptly notify the other Party or Parties hereto to which such obligations are owed, either in writing or orally; provided that any such oral notification shall be confirmed in writing as soon as practicable after being delivered.  In the event of any such excused delay, the time for performance shall be extended for a period equal to the time lost by reason of the delay.  If (x) Services are suspended as a result of such excused delay, (y) the suspension has a material and negative impact on Recipient’s business operations and (z) Provider cannot readily reinstate the relevant Services, Provider will use commercially reasonable efforts to assist Recipient in securing alternative services to minimize such negative impact on Recipient.
