5.5 Sycamore may independently establish a Sycamore Price File with a particular Vendor to supply a specific component for Products and/or Services by Supplier. In that event, Sycamore shall notify Supplier of the SPF. To extent that Sycamore does not establish an SPF with respect to any and all other components, Supplier shall establish an SSP file for such components. Supplier shall issue its purchase orders in accordance with the pricing of the SPF for all SPF components and the SSP for other components. In the event that any SPF terms and conditions with a particular vendor conflicts with any provision in this Agreement, Supplier shall not be obligated to perform such conflicting terms and conditions within this Agreement and Sycamore shall waive any such claims of non-performance under this Agreement with respect to the specific purchase order in question.

5.6 Purchase Price Variance

5.6.1 “PPV” occurs when the Supplier is not able to purchase an SPF component at the SPF price. For SPF components only, in the event that the Supplier is not able to purchase a component at the then current SPF price, then Supplier must provide prompt written notice to Sycamore in advance of placing any purchase orders. Such notice shall be in the form of the Variance Authorization Form attached hereto as Exhibit A, and Supplier shall attach the following documentation to such form or provide such information electronically:

• Sycamore Purchase Order Number which created the demand, and

• Vendor quotation including price, quantity, and delivery date.

Sycamore must give prior written approval of each and every Supplier purchase order to a Vendor which varies from the price in the then current SPF. If Supplier does not give written notice of Purchase Price Variance prior to placing its purchase order with the Vendor, then the PPV claim against Sycamore is waived. In addition to the foregoing, in the event that the Supplier determines that there are expedite or premium charges for any SSP component during [ * ] after the parties have agreed upon the costed xxxx of materials for that [ * ] pursuant to Section 6.2 below, Supplier shall provide written notice to Sycamore in advance of placing any such purchase orders and must obtain Sycamore’s prior written approval. Such notice shall be in the form of the Variance Authorization Form attached hereto as Exhibit A, and Supplier shall attach the following documentation to such form or provide such information electronically:

• Sycamore Purchase Order Number which created the demand, and

• Vendor quotation including price, quantity, and delivery date.

Notwithstanding the foregoing, in no event shall Supplier request or be entitled to recover expedite or premium charges for any SSP component to the extent it has failed to order such components in a timely and prudent manner using reasonable business practices in order to meet the scheduled Ship Date.

5.7 At Sycamore’s discretion, Sycamore approved purchase price variance changes will be processed on a case by case basis under either Section 10.3 Component Inventory Buy Down or under Section 5.6, but not under both provisions. To the extent that Sycamore elects to process a purchase price variance under Section 5.6, Supplier shall promptly issue either a credit memo or an invoice (in accordance with Section 16.3) following issuance by Sycamore of a Purchase Order to Sycamore reflecting the purchase pricing variances identified through this Purchase Price Variance Process. Disagreement on any aspect of this process shall be resolved through the Dispute Resolution Process set out in Section 31.0.

5.8 In the event that Sycamore establishes an SPF and issues a Sycamore Purchase Order to a Vendor, Sycamore may, at its discretion, transfer such Sycamore Purchase Order to the Supplier and such Purchase Order, subject to Supplier’s agreement in writing to transfer the same, shall be treated by the parties as having been initially issued directly by the Supplier to the Vendor. Upon Supplier’s consent to transfer such purchase order, Supplier shall issue its own purchase order to the Vendor to substitute for the original Sycamore purchase order.

5.9 At Sycamore’s cost for its out-of-pocket expenses, Sycamore has the right to audit the purchasing practices and records utilized by Supplier. Such audit rights shall include but not be limited to the right to audit purchase price variances approved under Section 5.6.1, in which case Supplier shall provide Sycamore with the following information: the Sycamore Purchase Order which created the demand, the Supplier purchase order number with Vendor for the PPV material, the date Supplier
