10.  GENERAL PROVISIONS.

10.1  Entire Agreement.  This Agreement (including any applicable Statements of Work) constitutes the entire agreement between the parties with regard to, and supersedes all prior negotiations, understandings or agreements (oral or written) between the parties relating to, the subject matter of this Agreement (and all past dealing or industry custom).  Any inconsistent or additional terms on any related purchase order, confirmation or similar form, even if signed by the parties after the date hereof, shall have no force or effect under this Agreement.  This Agreement may be executed in one or more counterparts, each of which is an original, but together constituting one and the same instrument.  Execution of a facsimile copy shall have the same force and effect as execution of an original, and a facsimile signature shall be deemed an original and valid signature.  No changes, modifications or waivers may be made to this Agreement unless in writing and signed by both parties.  The failure of either party to enforce its rights under this Agreement at any time for any period will not be construed as a waiver of such rights.  Except as specifically provided otherwise, each right and remedy in this Agreement is in addition to any other right or remedy, at law or in equity, and the exercise of one right or remedy will not be deemed a waiver of any other right or remedy.  If any provision of this Agreement is determined to be illegal or unenforceable, that provision will be limited or eliminated to the minimum extent necessary so that this Agreement will otherwise remain in full force and effect and enforceable.

10.2  Governing Law.  This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to its conflicts of law provisions or any rule that would cause the application of the laws of any other jurisdiction.  The sole jurisdiction and venue for actions related to this Agreement will be the state or federal courts located in New York, and both parties consent to the jurisdiction of such courts with respect to any such action.  In any action or proceeding to enforce or interpret this Agreement, the prevailing party will be entitled to recover the costs and expenses (including reasonable attorneys’ fees) that it incurred in connection with such action or proceeding and enforcing any judgment or order obtained.

10.3  Relief.  Each party agrees that, in the event of any breach or threatened breach of Section 3 or 4, the non-breaching party will suffer irreparable damage for which it will have no adequate remedy at law.  Accordingly, the non-breaching party shall be entitled to injunctive and other equitable remedies to prevent or restrain, temporarily or permanently, such breach or threatened breach, without the necessity of posting any bond or surety.  Such remedies shall be in addition to any other remedy that the non-breaching party may have at law or in equity.

10.4  Notices.  All notices under this Agreement will be in writing, in English and will be deemed to have been duly given when received, if personally delivered; when receipt is electronically confirmed, if transmitted by facsimile or e-mail; the day after being sent, if sent for next day delivery by recognized overnight delivery service; or upon receipt, if sent by certified or registered mail, return receipt requested.

10.5  Assignment.  This Agreement and the rights and obligations hereunder may not be assigned or otherwise transferred by either party without the prior written consent of the other, except that either party (without consent) may assign its rights and obligations hereunder to any of its Affiliates or to any successor to all or substantially all of its business that concerns this Agreement (whether by sale of stock or assets, merger, consolidation or otherwise).  Any attempted transfer in violation hereof will be void and of no effect.  Synchronoss may also subcontract performance of any Service.  This Agreement will be binding upon, and inure to the benefit of, the successors, representatives, and permitted assigns of the parties.

10.6  Independent Contractors.  The parties shall be independent contractors in their performance under this Agreement, and nothing contained herein will constitute either party as the employer, employee, agent or representative of the other party, or both parties as joint venturers or partners for any purpose.

4

10.7  No Interference.  During the farm of this Agreement and for 1 year thereafter, neither party will directly or indirectly recruit, employ or retain any employee of the other party, or otherwise solicit, induce or influence any employee to leave their employment with the other party, or attempt to do so, except with the other party’s written consent.

10.8  Publicity.  Within 30 days after the Effective Date, the parties (jointly or separately, as the parties may decide) shall issue a press release approved by both parties (such approval not to be unreasonably delayed or withheld) concerning the arrangements in this Agreement.  During the term of this Agreement, each party authorizes the other to include its name and logos in partner listings that may be published as part of its marketing efforts.  Except for the foregoing, any news release, public announcement, advertisement or publicity released by either party concerning this Agreement will be subject to prior approval of the other party, which shall not be unreasonably withheld or delayed.

IN WITNESS WHEREOF, intending to be legally bound, the parties have caused their duly authorized officers to execute this Agreement as a sealed instrument, as of the Effective Date.
