Subject to the terms and conditions of this Agreement, at the Effective Time, each share of Company Series C-1 Preferred Stock that is issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without the need for any further action on the part of Acquirer, Sub, Company or the holder thereof (except as expressly provided herein), be converted into and represent the right to receive the Cash Amount Per Series C-1 Share, without interest.

               (vii) Unvested Company Shares. The payout of cash pursuant to this Section 2.2(b) in exchange for Unvested Company Shares issued and outstanding immediately prior to the Effective Time shall be subject to the same restrictions and vesting arrangements that were applicable to such Unvested Company Shares immediately prior to or at the Effective Time. Furthermore, cash otherwise payable pursuant to this Section 2.2(b) in exchange for each Unvested Company Share that is issued and outstanding immediately prior to the Effective Time (“Unvested Cash”) shall not automatically be payable by Acquirer at the Effective Time, and shall instead be paid out by Acquirer no later than thirty (30) days following the calendar month in which such Unvested Company Share would have become vested under the vesting schedule in place for such share immediately prior to or at the Effective Time (subject to the restrictions and other terms of such vesting schedule), less the amount of such newly vested cash which shall be deposited in escrow in accordance with Section 2.4. All amounts payable pursuant to this Section 2.2(b)(vii) shall be subject to any required withholding of Taxes and shall be paid without interest. A portion of such newly vested cash so distributed will be treated as imputed interest to the extent required under the Code and the regulations promulgated thereunder. All outstanding rights to repurchase Unvested Company Shares that the Company may hold or similar restrictions in the Company’s favor immediately prior to the Effective Time (all such rights, the “Repurchase Rights”) shall be assigned to Acquirer in the Merger and shall thereafter be exercisable by Acquirer upon the same terms and subject to the same conditions that were in effect immediately prior to the Effective Time except that Repurchase Rights may be exercised by Acquirer by retaining the Unvested Cash into which such Unvested Company Shares have been converted and paying to the former holder thereof the repurchase price in effect for each such share subject to that Repurchase Right immediately prior to the Effective Time. No Unvested Cash, or right thereto, may be pledged, encumbered, sold, assigned or transferred (including any transfer by operation of law), by any Person, other than Acquirer, or be taken or reached by any legal or equitable process in satisfaction of any debt or

other liability of such Person, prior to the distribution to such Person of such Unvested Cash in accordance with this Agreement. The parties hereby acknowledge and agree that all Unvested Cash shall be treated as an installment obligation for purposes of Section 453 of the Code, and no party shall take any action or filing position inconsistent with such characterization.

               (viii) Assumption of Company Options. At the Effective Time, each Company Option held by a Continuing Employee that is unexpired, unexercised and outstanding immediately prior to the Effective Time shall, on the terms and subject to the conditions set forth in this Agreement, be assumed and converted by Acquirer in accordance with Section 5.17. As set forth in Section 5.17, each assumed Company Option that immediately prior to the Effective Time was not fully vested shall be subject to the same vesting arrangements that were applicable to such Company Option immediately prior to or at the Effective Time. Acquirer will not assume any Company Options held by Persons that are not Continuing Employees.

               (ix) Rounding; Other Provisions. The amount of cash each Company Securityholder is entitled to receive for the shares of Company Stock held by such Company Securityholder shall be rounded to the nearest cent and computed after aggregating all cash amounts for all shares of Company Stock held by such Company Securityholder. The provisions of this Section 2.2(b) are subject to Section 2.2(e) (regarding withholding rights), Section 2.3 (regarding rights of holders of Dissenting Shares), and Section 2.4 (regarding the withholding of the Escrow Fund).

          (c) Cancellation of Company-Owned Stock. Notwithstanding Section 2.2(b), each share of Company Capital Stock held by Company immediately prior to the Effective Time will be canceled and extinguished without any conversion thereof and without the issuance or payment of any consideration.

          (d) Termination of Company Warrants. At the Effective Time, each Company Warrant that is unexpired, unexercised, and outstanding immediately prior to the Effective Time shall terminate.

          (e) Withholding Rights. Acquirer, the Surviving Corporation, and the Exchange Agent will be entitled to deduct and withhold from the consideration otherwise deliverable under this Agreement, and from any other payments otherwise required pursuant to this Agreement, to any person entitled to payment under this Agreement, including any holder of any shares of Company Common Stock, Company Options, or Company Warrants, such amounts as Acquirer, the Surviving Corporation, or the Exchange Agent is required to deduct and withhold with respect to any such deliveries and payments under the Code or any provision of state, local, provincial or foreign Tax law. To the extent that amounts are so withheld, such withheld amounts will be treated for all purposes of this Agreement as having been delivered and paid to such holders in respect of which such deduction and withholding was made.

     2.3 Dissenting Shares. Notwithstanding anything contained herein to the contrary, any Dissenting Shares shall not be converted into the right to receive the cash amount provided for in Section 2.2(b), but shall instead be converted into the right to receive such consideration as may be determined to be due with respect to any such Dissenting Shares pursuant to California Law and/or Delaware Law. Each holder of Dissenting Shares who, pursuant to the provisions of California Law and/or Delaware Law, becomes entitled to payment thereunder for such shares shall receive payment therefor in accordance with California Law and/or Delaware Law (but only after the value therefor shall have been agreed upon or finally determined pursuant to such provisions). If, after the Effective Time, any Dissenting Shares shall lose their status as Dissenting Shares, then any such shares shall immediately be converted into the right to receive the cash payable pursuant to Section 2.2(b), subject to the provisions of Section 2.3(e) and Section 2.4, in respect of such shares as if such shares never had been Dissenting

Shares, and Acquirer shall issue and deliver to the holder thereof, as promptly as reasonably practicable, following the satisfaction of the applicable conditions set forth in Section 6.2, the amount of consideration to which such holder would be entitled in respect thereof under Section 2.2 as if such shares never had been Dissenting Shares. The Company shall give Acquirer (i) prompt notice of any demands for appraisal or purchase received by the Company, withdrawals of such demands, and any other instruments served pursuant to California Law and/or Delaware Law and received by the Company and (ii) the right to direct all negotiations and proceedings with respect to demands for appraisal or purchase under California Law and/or Delaware Law. The Company shall not, except with the prior written consent of Acquirer, or as otherwise required under California Law and/or Delaware Law, voluntarily make any payment or offer to make any payment with respect to, or settle or offer to settle, any claim or demand in respect of any Dissenting Shares. The payout of consideration under this Agreement to the stockholders of the Company (other than to holders of Dissenting Shares who shall be treated as provided in this Section 2.3 and under California Law and/or Delaware Law) shall not be affected by the exercise or potential exercise of appraisal rights or dissenters’ rights under California Law and/or Delaware Law by any other stockholder of the Company.

     2.4 Escrow Fund. At the Effective Time and pursuant to the Escrow Agreement, Acquirer will withhold from the cash payable to each Company Stockholder in the Merger upon conversion of his/her/its shares of outstanding Company Common Stock and outstanding Company Preferred Stock pursuant to Section 2.2(b) and will as soon as reasonably practicable after the Effective Time deposit into escrow with the Escrow Agent such Company Stockholder’s Pro Rata Share of the amount of cash equal to the product obtained by multiplying (a) 15% by (b) the Merger Consideration (the aggregate cash so placed into escrow, and any earnings on such cash, the “Escrow Fund”). The Escrow Fund shall constitute security for the indemnification obligations of the Company Shareholders pursuant to Article 10. The parties hereby acknowledge and agree that the Escrow Fund shall be treated as an installment obligation for purposes of Section 453 of the Code, and no party shall take any action or filing position inconsistent with such characterization. The parties further agree that, consistent with Proposed Treasury Regulation Section 1.468B-8, for Tax reporting purposes, all interest or other income earned from the investment of the Escrow Fund or any portion thereof in any Tax year shall be reported as allocated to Acquirer until the distribution of the Escrow Fund (or portion thereof) is determined and thereafter to Acquirer and the Company Shareholders in accordance with their respective interests in the Escrow Fund consistent with Proposed Treasury Regulation Section 1.468B-8. The Escrow Fund shall, to the maximum extent possible, be vested cash not subject to any repurchase rights or other restrictions, and any Unvested Cash so placed in escrow shall vest prior to any Unvested Cash not placed in escrow.

     2.5 Adjustments. In the event of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into capital stock), reorganization, reclassification, combination, recapitalization or other like change with respect to the Company Capital Stock occurring after the date hereof and prior to the Effective Time, all references in this Agreement to specified numbers of shares of any class or series affected thereby, and all calculations provided for that are based upon numbers of shares of any class or series (or trading prices therefor) affected thereby, including the cash amount per share to be paid to shares of Company Preferred Stock as contemplated herein, shall be equitably adjusted to the extent necessary to provide the parties the same economic effect as contemplated by this Agreement prior to such stock split, reverse stock split, stock dividend, reorganization, reclassification, combination, recapitalization or other like change.

     2.6 Total Merger Consideration. Notwithstanding anything to the contrary contained in this Agreement, in no event shall the aggregate consideration paid by Acquirer to the Company Securityholders exceed the Merger Consideration.

     2.7 Effects of the Merger.

          (a) General. At the Effective Time, the effect of the Merger will be as provided in this Agreement and the applicable provisions of the Delaware Law.

          (b) Certificate of Incorporation. The Certificate of Incorporation of Sub immediately prior to the Effective Time will be the Certificate of Incorporation of the Surviving Corporation immediately after the Effective Time until thereafter amended in accordance with the provisions thereof or as provided by law; provided, however, that Article I of the Certificate of Incorporation of the Surviving Corporation will be amended at the Effective Time to read: “The name of the corporation is “MailFrontier, Inc.”

     2.8 Further Assurances. Company agrees that if, at any time after the Effective Time, Acquirer believes or is advised that any further deeds, assignments or assurances are reasonably necessary or desirable to vest, perfect, confirm or continue in the Surviving Corporation, Sub or Acquirer title to any property or any right of Company as provided herein, Acquirer and any of its officers are hereby authorized by Company to execute and deliver all such proper deeds, assignments and assurances and do all other things necessary or desirable to vest, perfect, confirm or continue title to such property or rights in the Surviving Corporation, Sub or Acquirer and otherwise to carry out the purposes of this Agreement, in the name of Company or otherwise. The parties further agree that, upon Acquirer’s request, the parties will amend this Agreement to cause Company to merge into Sub (with Sub to be the surviving corporation) or to cause Company to merge into a different direct or indirect Subsidiary of Acquirer.

     2.9 Rights Not Transferable. The rights of the Company Stockholders as of immediately prior to the Effective Time, are personal to each such holder and will not be transferable for any reason otherwise than by operation of law, will or the laws of descent and distribution. Any attempted transfer of such right by any holder thereof (otherwise than as permitted by the immediately preceding sentence) will be null and void.

Except to the extent that a reserve for Taxes has been established on the Balance Sheet, all Returns are true, complete and correct and were prepared in substantial compliance with all Applicable Laws. Company has paid all Taxes due and owing (whether or not shown on any Return) for all periods through the Balance Sheet Date, except to the extent reserves for Taxes have been established on the Balance Sheet. Company currently is not the beneficiary of any extension of time within which to file any Return. Schedule 3.8(a) of the Company Disclosure Letter shows a list of Returns and their respective due dates for the period ending on or before the Closing Date and which Returns are not yet due and have not been filed.

          (b) As of the Balance Sheet Date, Company has no Liability for Taxes in excess of the amount so paid, except to the extent adequate reserves for Taxes have been established in the Balance Sheet. Since the Balance Sheet Date, Company has not incurred any Liability for Taxes arising from extraordinary gains or losses, as that term is used in GAAP, outside the ordinary course of business consistent with past custom and practice. The Company will have no Liability for unpaid Taxes as of the Closing Date that was not included in the calculation of Net Working Capital. There are no Encumbrances for Taxes (other than Taxes not yet due and payable) upon any of the assets of Company.

No Return of Company has ever been audited by the Internal Revenue Service or any other Tax agency or authority, no such audit is in progress and Company has not been notified of any request for such an audit or other examination. No director or officer (or employee responsible for Tax matters) of Company expects any Governmental Authority to assess any

19

additional Taxes for any period for which Returns have been filed, except to the extent that a reserve for Taxes has been established on the Balance Sheet. No claim has ever been made by a Governmental Authority in a jurisdiction where Company does not file Returns that Company is or may be subject to taxation by that jurisdiction. No adjustment relating to any Returns filed by Company has been proposed in writing by any Tax authority to Company (or any representative thereof).

     10.4 Appointment of Representatives. Each Company Stockholder approves the designation of and designates Anne Bonaparte and Sonja Hoel as the joint representatives of the Company Stockholders and as the attorney-in-fact and agent for and on behalf of each Company Stockholder (the “Representatives”) with respect to claims for indemnification pursuant to this Article 10 and the taking by the Representatives of any and all actions and the making of any decisions required or permitted to be taken by the Representatives pursuant to this Agreement, including the exercise of the power to: (a) authorize the release or delivery to Acquirer of the cash in the Escrow Fund in satisfaction of indemnification claims of any Indemnified Person pursuant to this Article 10; (b) agree to, negotiate, enter into settlements and compromises of, and comply with orders of courts with respect to, any claim for indemnification pursuant to this Article 10; (c) resolve, settle or compromise any claim for indemnification made pursuant to this Article 10; and (d) take all actions necessary in the judgment of the Representatives for the accomplishment of the foregoing.

The Company Stockholders will be bound by all actions taken and documents executed by the Representatives in connection with this Article 10, and the Indemnified Persons will be entitled to rely on any action or decision of the Representatives. In performing the functions specified in this Agreement, the Representatives will not be liable to any Company Stockholder in the absence of gross negligence or willful misconduct on the part of the Representatives. Each Company Stockholder will severally, and not jointly, on a pro rata basis based on such Company Stockholder’s Pro Rata Share, indemnify and hold harmless the Representatives from and against any Liability incurred without gross negligence or willful misconduct on the part of the Representatives and arising out of or in connection

with the acceptance or administration of his duties hereunder. Any out-of-pocket costs and expenses reasonably incurred by the Representatives in connection with actions taken by the Representatives pursuant to the terms of this Article 10 (including the hiring of counsel and the incurring of legal fees and costs) will be paid from the Escrow Fund, such amount not to exceed $50,000.

     10.5 Notice of Claim. As used herein, “Claim” means a claim for indemnification of any Indemnified Person for Damages pursuant to this Article 10. Acquirer will give a written notice of a Claim executed by an officer of Acquirer (a “Notice of Claim”), whether for its own Damages or for Damages incurred by any other Indemnified Person. Acquirer will deliver a Notice of Claim based on, arising from, relating to or caused by:

          (a) any item specified in Section 10.2; or

          (b) the assertion, whether oral or in writing, against any Indemnified Person of a claim, demand, suit, action, cause of action, dispute, arbitration, investigation, inquiry or proceeding brought by a third party against such Indemnified Person (in each such case, a “Third-Party Claim”) that is based on, arises out of, relates to or is caused by any item specified in Section 10.2.

          No delay on the part of Acquirer in giving the Representatives a Notice of Claim will relieve the Representatives or any Company Stockholder from any of its obligations pursuant to this Article 10 unless (and then only to the extent that) the Representatives or such Company Stockholder is materially prejudiced thereby.

     10.6 Defense of Third-Party Claims.

          (a) Acquirer will defend any Third-Party Claim, and the costs and expenses incurred by Acquirer in connection with such defense (including reasonable attorneys’ fees, other professionals’ and experts’ fees and court or arbitration costs) will be included in the Damages for which Acquirer may seek indemnification pursuant to a Claim made by any Indemnified Person hereunder. Notwithstanding the foregoing, (i) the Representatives may participate in any proceeding with counsel of its choice and at its expense and (ii) if Acquirer fails to defend against, negotiate, settle or otherwise deal with such Third Party Claim as provided in this Section 10.6(a), then the Indemnifying Party shall have the right to defend against, negotiate, settle or otherwise deal with the Third Party Claim in good faith and otherwise in such manner as the Representatives deems appropriate.

          (b) The Representatives will have the right to receive copies of all pleadings, notices and communications with respect to any Third-Party Claim to the extent that receipt of such documents by the Representatives does not affect any privilege relating to the Indemnified Person and may participate at its own expense in settlement negotiations with respect to such Third-Party Claim. No Indemnified Person will enter into any settlement of a Third-Party Claim without the Representative’s prior written consent (which consent will not be unreasonably withheld or delayed); provided, however, that if (and only if) the Representatives has consented in writing to any such settlement, then the Representatives will be deemed to have accepted the related Claim by any Indemnified Person for indemnification pursuant to Section 10.2 for the amount of such settlement, and the Company Stockholders will remain responsible to indemnify the Indemnified Persons for all Damages they may incur arising out of, resulting from or caused by the Third-Party Claim to the fullest extent provided in this Article 10. If the Representatives have not consented in writing to any such settlement, then the Representatives shall not be precluded from disputing the amount of any Claim of an Indemnified Party resulting from a Third Party Claim.

     10.7 Contents of Notice of Claim. Each Notice of Claim by Acquirer given pursuant to Section 10.5 will contain the following:

          (a) a statement that the Indemnified Person has incurred, paid or accrued (in accordance with GAAP) or, in good faith, believes it will have to incur, pay or accrue (in accordance with GAAP) Damages in an aggregate stated amount directly or indirectly arising out of, resulting from or in connection with such Claim (which amount may be the amount of damages claimed by a third party in a Third-Party Claim); and

          (b) a brief description of the facts, circumstances or events giving rise to the alleged Damages, including copies of any formal demand or complaint and a good faith estimate of the amount of Damages.

     10.8 Resolution of Notice of Claim. Each Notice of Claim delivered by Acquirer will be resolved as follows:

          (a) Uncontested Claims. If, within 30 calendar days after a Notice of Claim is received by the Representatives, the Representatives do not contest such Notice of Claim in writing to the Escrow Agent and Acquirer as provided in Section 10.8(b), then (i) the Representatives will be conclusively deemed to have consented, on behalf of all Company Stockholders, to the recovery by the Indemnified Person of the full amount of the Damages specified in the Notice of Claim, including the forfeiture of cash in the Escrow Fund and, without further notice, to have stipulated to the entry of a final judgment for damages against the Company Stockholders for such amount in any court having jurisdiction over the matter where venue is proper and (ii) the Escrow Agent will distribute to Acquirer an amount of cash equivalent to the amount of such Damages.

          (b) Contested Claims. If the Representatives gives the Escrow Agent and Acquirer written notice contesting all or any portion of a Notice of Claim (a “Contested Claim”) within the 20-day period specified in Section 10.8(a), then such Contested Claim will be resolved by either (i) a written settlement agreement executed by Acquirer and the Representatives or (ii) in the absence of such a written settlement agreement, a final judgment by a court of competent jurisdiction.

     10.9 Release of Remaining Cash in Escrow Fund.

          (a) Within 10 business days following the 18-month anniversary of the Effective Time, the Escrow Agent will deliver to the Company Stockholders the portion of the Escrow Fund in excess of the amount of the cash that is necessary to satisfy all unsatisfied or disputed Claims specified in any Notice of Claim delivered to the Representatives before the 18-month anniversary of the Effective Time.

          (b) If any Claims are pending but not resolved on the 18-month anniversary of the Effective Time, then the Escrow Agent will retain possession and custody of the amount of cash in the Escrow Fund that equals the total maximum amount of Damages then being claimed by the Indemnified Persons in all such pending Claims, and, as soon as all such Claims have been resolved, the Escrow Agent will deliver to the Company Stockholders any remaining portion of the cash in the Escrow Fund not required to satisfy such Claims.

ARTICLE 11
General Provisions

     11.1 Governing Law; Submission to Jurisdiction. The internal laws of the State of Delaware, irrespective of its choice of law principles, will govern the validity of this Agreement, the construction of its terms, and the interpretation and enforcement of the rights and duties of the parties hereto. Each of the parties hereto (a) submits to the exclusive jurisdiction of the courts of the State of California and the Federal Courts of the United States of America within the County of Santa Clara in the State of

California, the place where this Agreement was entered and is to be performed, in any action or proceeding arising out of or relating to this Agreement, (b) agrees that all claims in respect of the action or proceeding may be heard and determined in any such court, and (c) agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court. Each of the parties hereto waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto. Any party may make service on another party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for giving of notices in Section 11.9. Nothing in this Section 11.1, however, will affect the right of any party to serve legal process in any other manner permitted by law.

     11.2 Assignment; Binding Upon Successors and Assigns. No party hereto may assign any of its rights or obligations hereunder without the prior written consent of the other parties hereto. This Agreement will be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Any assignment in violation of this Section 11.2 will be void.

     11.3 Severability. If any provision of this Agreement, or the application thereof, is for any reason held to any extent to be invalid, illegal or unenforceable, then the remainder of this Agreement and the application thereof will nevertheless remain in full force and effect so long as the economic and legal substance of the transactions contemplated by this Agreement are not affected in any manner materially adverse to any party hereto. Upon such determination that any provision is invalid, illegal or unenforceable, the parties agree to replace such provision with a valid, legal and enforceable provision that will achieve, to the maximum extent legally permissible, the economic, business and other purposes of such provision.

     11.4 Counterparts. This Agreement may be executed in any number of counterparts, each of which will be an original as regards any party whose signature appears thereon and all of which together will constitute one and the same instrument. This Agreement will become binding when one or more counterparts hereof, individually or taken together, will bear the signatures of all parties reflected herein as signatories and have been delivered by each party to this Agreement to each other party to this Agreement.

     11.5 Other Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred by this Agreement or by law on such party, and the exercise of any one remedy will not preclude the exercise of any other. Notwithstanding the foregoing, any termination of this Agreement prior to the Closing pursuant to Article 9 will be governed by the terms of Article 9. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties will be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction.

     11.6 Amendment and Waivers. This Agreement may not be amended or modified except by a written instrument signed by Acquirer, Sub and Company. This Agreement may be amended by the parties hereto as provided in this Section 11.6 at any time before or after approval of this Agreement by the Company Stockholders; provided, however, that, after such approval, no amendment will be made that by Applicable Laws requires the further approval of the Company Stockholders without obtaining such further approval. At any time prior to the Effective Time, each of Company and Acquirer, by action taken by its Board of Directors, may, to the extent legally allowed: (a) extend the time for the performance of any of the obligations or other acts of the other contained herein or in any agreement, certificate or document delivered pursuant hereto; (b) waive any inaccuracies in the representations and warranties made to it contained herein or in any agreement, certificate or document delivered pursuant

hereto; and (c) waive compliance with any of the agreements or conditions for its benefit contained herein or in any agreement, certificate or document delivered pursuant hereto. No such extension or waiver will be effective unless signed in writing by the party against whom such extension or waiver is asserted. The waiver by a party of any breach hereof or default in the performance hereof will not be deemed to constitute a waiver of any other breach or default or any succeeding breach or default. The failure of any party to enforce any of the provisions hereof will not be construed to be a waiver of the right of such party thereafter to enforce such provisions.

     11.7 Expenses. Each party will bear its respective Transaction Expenses. The Merger Consideration will be reduced by the amount of Transaction Expenses (excluding any Transaction Expenses to be paid on behalf of Pavani Diwanji, Anne Bonaparte and Brian Wilson, pursuant to the Transaction Expenses Agreement) paid or payable by the Company that has not been paid. If, for any reason, Acquirer or the Surviving Corporation directly or indirectly pays any Transaction Expenses that are not reflected in the Transaction Expenses Schedule, then Acquirer will be entitled to treat such undisclosed Transaction Expenses as Damages recoverable under Section 10.2.

     11.8 Attorneys’ Fees. Should suit be brought to enforce or interpret any part of this Agreement, the prevailing party will be entitled to recover, as an element of the costs of suit and not as damages, reasonable attorneys’ fees to be fixed by the court (including costs, expenses and fees on any appeal). The prevailing party will be entitled to recover its costs of suit, regardless of whether such suit proceeds to final judgment.

     11.9 Notices. All notices and other communications required or permitted under this Agreement will be in writing and will be either hand delivered in person, sent by facsimile, sent by certified or registered first-class mail, postage pre-paid, or sent by nationally recognized express courier service. Such notices and other communications will be effective upon receipt if hand delivered or sent by facsimile, five days after mailing if sent by mail, and one day after dispatch if sent by express courier, to the following addresses, or such other addresses as any party may notify the other parties in accordance with this Section 11.9:
