(a) Reports. Any reports Vendor provides to Microsoft must be accurate, complete and timely. Vendor will correct any error or omission in any report within five days after becoming aware of the error or omission.

(b) Records. During the Term and for 4 years thereafter, Vendor will keep all usual and proper records and books of account relating to the Products and Services and all quality and performance reports related to the Products or Services (the “Vendor Records”). Vendor will maintain any documentation required by Microsoft in connection with the United States Xxxxxxxx-Xxxxx Act of 2002. Vendor will not do or omit to do anything that could prejudice Microsoft’s compliance with that Act.

(c) Audits, inspections and refunds.

(1) During the period described in Section 15(b)(Records), Microsoft may audit Vendor Records and/or inspect Vendor facilities to verify Vendor’s statements and compliance with this Agreement. Audits and inspections will be conducted by Microsoft or an independent certified public accountant or consultant selected by Microsoft. Vendor will provide Microsoft’s designated auditors with reasonable access to the relevant Vendor Records, Microsoft contracts and facilities. The auditors will have the ability to photocopy Vendor Records for audit evidence.

(2) If an audit shows that Vendor overcharged Microsoft by 5% or more during any audited time period, Vendor will:

(i) Pay Microsoft for all reasonable costs and expenses incurred in conducting the audit; and

(ii) Re-compute the amount due and immediately refund to Microsoft all overpayments based on the actual amounts due and owing, plus interest at one half of one percent (.5%) per month on the overpayment. Microsoft will be responsible for the costs it incurs for all other audits and inspections conducted under this Section 15(c) (Audit, inspections and refunds).

(d) Financial Reporting. On a quarterly basis, Vendor agrees to disclose to Microsoft reasonably sufficient information for Microsoft to verify Vendor’s solvency and ability to continue to perform its obligations under this Agreement. In addition, within ten (10) calendar days after Vendor learns that it has become or will become insolvent, Vendor will submit publicly available financial information which is reasonably sufficient to allow Microsoft to determine whether Vendor will be capable of continuing to perform its obligation under this Agreement. If Microsoft determines Vendor will not be capable of continued performance, Microsoft may terminate the Agreement immediately without further obligation to Vendor.

SECTION 16 Miscellaneous

(a) Relationship. The parties are independent contractors. This Agreement does not create an exclusive relationship between the parties. Vendor’s employees and Subcontractors are not Microsoft employees. Vendor will pay all salaries, taxes, insurance, and benefits with respect

-13-

to its personnel. Vendor will provide Microsoft with satisfactory proof of independent contractor status upon request.

(b) Notices. Except as specifically set out in this Agreement, all notices will be:

(1) In writing and sent to the contact(s) and location(s) specified on page 1 of this Agreement; and

(2) Deemed given on the day received by the addressee.

Each party will notify the other in writing of any changes to their respective contact information.

(c) Governing law; jurisdiction. The laws of the State of Washington govern this Agreement. If federal jurisdiction exists, the parties consent to the exclusive jurisdiction and venue in the federal courts in King County, Washington. If not, the parties consent to exclusive jurisdiction and venue in the Superior Court of King County, Washington. If either Microsoft or Vendor employs attorneys to enforce any rights arising out of or relating to this Agreement, the prevailing party will be entitled to recover its reasonable attorneys’ fees, costs, and other expenses, including the costs and fees incurred on appeal or in a bankruptcy or similar action.

(d) Force majeure. Neither party will be liable for failure to perform any obligation under this Agreement to the extent such failure is caused by a force majeure event. This includes acts of God, natural disasters, war, civil disturbance, action by governmental entity, strike, and other causes beyond the party’s reasonable control. The party affected by the force majeure event will provide notice to the other party within a commercially reasonable time and will use its best efforts to resume performance. Obligations not performed due to a force majeure event will be performed as soon as reasonably possible when the force majeure event concludes.

(e) Assignment. Vendor will not sell, assign, transfer, pledge or encumber this Agreement or any right, or delegate any duty or obligation under this Agreement, by assignment or operation of law, without Microsoft’s prior written consent. Microsoft will not unreasonably withhold such consent. Vendor will be deemed to have assigned this Agreement if Vendor engages in a change of control transaction. Microsoft may assign this Agreement to any of its Affiliates. This Agreement will inure to the benefit of and bind all permitted successors, assigns, receivers and trustees of each party.

(f) No waiver. A party’s delay or failure to exercise any right or remedy will not result in a waiver of that or any other right or remedy.

(g) Severability. If any court of competent jurisdiction determines that any provision of this Agreement is illegal, invalid or unenforceable, the remaining provisions will remain in full force and effect.

(h) Nonexclusivity and no minimums. This Agreement does not grant Vendor an exclusive right or privilege to sell or otherwise provide to Microsoft any Products or Services. Microsoft may contract with any other party for comparable Products and Services. This Agreement does not require the purchase of any minimum value or minimum volume of the Products or Services.

(i) Entire agreement, precedence and amendment. This Agreement supersedes all prior and contemporaneous communications, whether written or oral, regarding the subject matter covered in this Agreement. In the event of a conflict between any parts of this Agreement not resolved expressly by its terms, the following order of precedence will apply:

(1) This Agreement (including any Microsoft policies and procedures referenced herein);

-14-

(2) A signed SOW, except to the extent that this Agreement or the SOW expressly provides that a particular section of the SOW takes precedence over a particular section of this Agreement; and

(3) Microsoft purchase order terms and conditions.

This Agreement may be modified only by a written agreement signed by a duly authorized representative of both parties. However, Microsoft may unilaterally modify the policies and procedures identified in Section 14 (Vendor to comply with Microsoft policies and procedure). This Agreement does not replace any separate written license agreement between Microsoft and Vendor.

(j) Counterparts. The parties may execute this Agreement in any number of counterparts. Each counterpart will be deemed an original and all counterparts will constitute one agreement binding on both parties. Facsimile or electronically authenticated signatures will be considered binding for all purposes.
