(a)    Consideration Advance.

The Consideration Advance may be paid in cash or shares of RingCentral Common Stock or a combination thereof, at RingCentral’s election, which election shall be notified to Avaya in writing within one (1) Business Day after the Effective Date. In the event RingCentral elects to make the Consideration Advance in whole or in part in shares of RingCentral Common Stock, (x) the number of shares of RingCentral Common Stock to be issued for the Consideration Advance shall equal (A) the value of the Consideration Advance (or portion thereof) that RingCentral elects to settle

in shares of RingCentral Common Stock, divided by (B) the RNG 5-day VWAP as of the Effective Date (subject to Section 5.4(b)(i)). For the avoidance of doubt, all Consideration Advances received by Avaya shall constitute properties of Avaya and may be used freely by Avaya.

(b)    Payment Mechanism. Any portion of the Consideration Advance to be paid in cash shall be paid as promptly as practicable after the Effective Date by wire transfer of immediately available funds to an account designated in writing by Avaya. If the Effective Date occurs (i) on a date that is during a Blackout Period or the five (5) trading day period after the expiration of a Blackout Period, then the shares of RingCentral Common Stock comprising the applicable portion of the Consideration Advance shall (A) be issued on the [***********************] following [***************************************************************************************************], and (B) notwithstanding Section 5.4(a)(x)(B), be determined based on the RNG 5-day VWAP as of the date of such issuance, or (ii) on any other date, then the shares of RingCentral Common Stock comprising any portion of the Consideration Advance shall be issued as promptly as reasonably practicable after the Effective Date, but in no event during a Blackout Period.

(c)    One Block Trade. If RingCentral makes the Consideration Advance in shares of RingCentral Common Stock, RingCentral shall be responsible for, and pay to Avaya the following amounts in connection with one block trade by Avaya of some or all of the shares of RingCentral Common Stock issued to satisfy the Consideration Advance: (i) the difference between the aggregate purchase price received by Avaya in such block trade and the product of (x) the closing price of the RingCentral Common Stock on the day such block trade is consummated and (y) the number of shares of RingCentral Common Stock sold in such block trade (the “Block Trade Spread”); and (ii) the reasonable and documented out-of-pocket attorneys’ fees and expenses of Avaya, which shall not exceed fifty thousand dollars ($50,000). Avaya shall use its commercially reasonable efforts to minimize the Block Trade Spread, including by bidding such block trade to J.P. Morgan Securities LLC, Goldman Sachs & Co. LLC, and any other financial banking institution or other broker-dealer reasonably requested by RingCentral and selecting the financial banking institution or other broker-deal providing for the lowest Block Trade Spread. RingCentral shall reasonably cooperate with Avaya and the banking institution or other broker-dealer selected for such block trade and as may be reasonably requested to facilitate and effectuate such block trade, including immediately removing any restrictive legend on the shares of RingCentral Common Stock sold in such block trade upon request of Avaya.

(d)    Consideration Credit. As incentive for RingCentral to make the Consideration Advance to Avaya in advance of the payment obligations pursuant to this Agreement, Avaya shall provide RingCentral a credit (the “Consideration Credit”), commencing on the receipt of the applicable amount of Consideration Advance, in an amount equal to 2.50% per annum of the daily outstanding Consideration Advance Balance (as defined below) in respect of the applicable Tranche, computed on the basis of a 365/366-day year for the actual number of days elapsed, which amount shall be added to the outstanding Consideration Advance Balance in respect of the applicable Tranche in arrears on the last day of March, June, September and December.

(e)    Exhaustion of Consideration Advance Balance. For purposes of this Agreement, “Consideration Advance Balance” of any Tranche means, as of a referenced date, the amount of the Consideration Advance under such Tranche actually received by Avaya from RingCentral as may have been increased or reduced prior to such date as a result of the addition of the accrued Consideration Credit to the then-outstanding Consideration Advance Balance of such Tranche as of each applicable quarter end pursuant to Section 5.4(d), any Clawback Credits, any exhaustion or replenishment pursuant to this Section 5.4(e), any return pursuant to Section 5.4(f) or Section 5.4(g), and any conversion pursuant to Section 5.4(h). For

so long as there is a positive Consideration Advance Balance, the Consideration Advance Balance shall be automatically reduced from time to time by any Upfront Payment or Recurring Payment that RingCentral is required to pay pursuant to the terms of Section 5.2 or Section 5.3, any other cash amounts that RingCentral is required to pay pursuant to Section 5.2, Section 5.3, or Section 5.4, or any purchase price of Avaya Endpoints that RingCentral is obligated to pay pursuant to a purchase of Avaya Endpoints pursuant to the process contemplated by the last sentence of Section 2.3(e) and, upon such automatic reduction, RingCentral’s payment obligations with respect thereto shall be irrevocably deemed satisfied with such reduction to apply, first to outstanding Consideration Advance Balance under Tranche 3, second to outstanding Consideration Advance Balance under Tranche 2 and third to outstanding Consideration Advance Balance under Tranche 1. Any Clawback Credit shall increase the Consideration Advance Balance of the Tranche previously reduced by the corresponding Upfront Payment giving rise to such Clawback Credit.

(f)    Return of Consideration Advance. Upon one Business Day’s written notice to RingCentral, Avaya shall be permitted to return all or any portion of the Consideration Advance Balance of any Tranche at any time by making a cash payment, by wire transfer of immediately available funds to an account designated in writing by RingCentral.

(g)    Return of Remaining Consideration Advance Balance. The outstanding Consideration Advance Balance shall be returned to RingCentral: (A) with respect to Tranche 1, by wire transfer of immediately available funds to an account designated in writing by RingCentral on the later of (x) the last day of the Initial Term and (y) [**************], (B) with respect to Tranche 2, by wire transfer of immediately available funds to an account designated in writing by RingCentral on [*****************] and (C) with respect to Tranche 3, by wire transfer of immediately available funds to an account designated in writing by RingCentral on the later of (x) the last day of the Initial Term and (y) [**************], unless, in each case of the foregoing clauses (A)-(C), (i) this Agreement has been terminated prior to such date pursuant to Section 11.2 or (ii) the Extension has occurred, in which case of clauses (i) and (ii), such outstanding Consideration Advance Balance of the applicable Tranche shall be returned upon the expiration or termination of this Agreement, subject to Section 5.4(h). If Avaya does not return the Consideration Advance Balance in full in cash within thirty (30) days after the applicable due date, Avaya shall pay a late fee in an amount of 2.00% per annum commencing on the thirty-first day after the applicable due date in addition to the Consideration Credit. For the avoidance of doubt, Consideration Credit shall continue to accrue on the outstanding Consideration Advance Balance pursuant to Section 5.4(e) until all such Consideration Advance Balance has been returned pursuant to this Section 5.4(g) or converted pursuant to Section 5.4(h).

(h)    Conversion of Consideration Advance Balance under Tranche 1; Conversion of Unexhausted Consideration Advance Balance.

(i)    With respect to Tranche 1, RingCentral shall have the right, but not the obligation, at any time on or after the [***********] anniversary of the Effective Date, to convert all then-outstanding Consideration Advance Balance under Tranche 1 into shares of Avaya Holdings pursuant to Section 5.4(h)(iii).

(ii)    In the event the Consideration Advance Balance under any Tranche is not repaid in full in cash on or before the date that is seven (7) Business Days after the applicable due date, RingCentral shall have the right, but not the obligation, from thereafter to convert any portion or all of such Consideration Advance Balance under any such applicable Tranche into shares of Avaya Holdings pursuant to Section 5.4(h)(iii).

(iii)    In each case of the foregoing clauses (i) and (ii), RingCentral may elect either (i) shares of Avaya Series A Preferred Stock at a price per share equal to the Stated Value (as defined in the Avaya Certificate of Designations) as of the Effective Date or (ii) shares of Avaya Common Stock at a price per share equal to the AVYA 20-day VWAP as of the date that RingCentral delivers to Avaya a Conversion Notice. Promptly (and in any event no later than six (6) trading days) after its receipt of a Conversion Notice, Avaya shall cause Avaya Holdings to issue to RingCentral the shares specified in such Conversion Notice. For purposes of this Agreement, a “Conversion Notice” shall mean a written notice delivered by RingCentral to Avaya specifying RingCentral’s election to exercise its conversion rights under this Section 5.4(h), the amount and Tranche of the Consideration Advance Balance to be so converted, and the number and class of shares into which RingCentral is electing to convert any portion of the Consideration Advance Balance of the applicable Tranche, including a calculation of such number and class of shares. Notwithstanding the foregoing, prior to the receipt of Stockholder Approval (as defined in the Avaya Certificate of Designations), Avaya shall not be required to issue any number of shares of Avaya Common Stock under this Section 5.4(h) that would exceed the number equal to (i) twenty-two million, one-hundred twenty-three thousand, twenty-two (22,123,022) shares of Avaya Common Stock minus (ii) the aggregate number of shares of Avaya Common Stock issued upon conversion of shares of Avaya Series A Preferred Stock pursuant to the Avaya Certificate of Designations since the Effective Date.

5.5    Currency and No Offsets. All amounts under this Agreement are stated and calculated, and shall be paid, in United States Dollars ($ U.S.). No payment obligation of a Party under this Agreement shall be offset or apply against any payment obligation of the other Party, other than the application to the Consideration Advance Balance of any Upfront Payment or Recurring Payment, any other payment obligations of RingCentral under this Agreement or the increase of the Consideration Advance Balance by any Clawback Credit pursuant to Section 5.4(e), to the extent such payment has been accrued in accordance with the terms of this Agreement.

5.6    Taxes.

(a)    Subject to the provisos in this Section 5.6(a), each Party shall be solely responsible for all Taxes imposed on that Party by applicable Law and Governmental Entities in respect of the payments and transactions made under this Agreement; provided that, notwithstanding the foregoing, all transfer, documentary, sales, use, stamp, registration and other similar Taxes and fees (including any penalties and interest thereon) incurred in connection with the issuance of Shares pursuant to this Agreement, shall be borne by the Issuer.

(b)    Notwithstanding anything to the contrary in this Agreement, each Party (and any permitted assignee pursuant to Section 12.2 and in the case of Avaya or any of Affiliate of Avaya designated by Avaya) shall be entitled to deduct and withhold from any amounts payable or otherwise deliverable pursuant to this Agreement any Taxes as may be required to be deducted or withheld therefrom under any provision of U.S. federal, state, local or non-U.S. Tax Law or other applicable Law, shall pay over to the appropriate Governmental Entity any such amounts deducted or withheld, and shall be provided any necessary Tax forms, including Form W-9 or the appropriate series of Form W-8, as applicable, or any similar information. The Parties shall use commercially reasonable efforts to cooperate with each other to reduce or minimize any amounts, if any, required to be deducted or withheld, including by applying, only if applicable and if any necessary documentation or certifications are provided and any other requirements are met, a reduced rate of withholding pursuant to an applicable tax treaty. Subject to the following proviso, to the extent any amounts are deducted or withheld and paid over to the appropriate Governmental Entity pursuant

to this Section 5.6(b), such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid; provided that to the extent a Party assigns its payment obligations under this Agreement pursuant to Section 12.2 to any Person that is not a U.S. corporation (or in the case of Avaya, Avaya designates an Affiliates of Avaya that is not a U.S. corporation to undertake payment of such payment obligation), to the extent such assignee (or designated Affiliate of Avaya) deducts or withholds any amounts pursuant to this Section 5.6(b) from any amounts payable by such assignee or such Affiliates of Avaya hereunder that would not have been required to have been deducted or withheld if no such assignment of such payment obligations or designation had been made (any such Taxes, “Additional Taxes”), then such Party or its assignee or designee shall pay such additional amounts (the “Additional Amounts”) as may be necessary to ensure that the net amount received by the Party entitled to such amount payable hereunder after such withholding or deduction of Additional Taxes (and after deducting or withholding any Taxes imposed or levied by a relevant taxing jurisdiction on the Additional Amounts) will equal the amounts that would have been received by the Party entitled to any such amounts payable hereunder had no such withholding or deduction been made. To the extent any amounts are deducted or withheld and paid over to the appropriate Governmental Entity pursuant to this Section 5.6(b), the applicable Party (or assignee or designee) undertaking such withholding shall provide the other Party, within thirty (30) days after the date of such deduction or withholding (or, if receipts, certificates or evidence are not available within thirty (30) days, as soon as practical thereafter), certified copies of tax receipts, certificates or other evidence of such withholding and payment reasonably acceptable to the other Party.

NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, (I) IN NO EVENT WILL A PARTY BE LIABLE FOR ANY PUNITIVE DAMAGES, AND (II) EXCEPT WITH RESPECT TO A PARTY’S BREACH OF SECTION 2.2 OR SECTION 8, RINGCENTRAL’S BREACH OF SECTION 6.2(f), SECTION 6.2(g), SECTION 6.2(h), OR THE LAST SENTENCE OF SECTION 5.3(a), OR A PARTY’S INFRINGEMENT OR MISAPPROPRIATION OF THE OTHER PARTY’S OR ITS AFFILIATES’ INTELLECTUAL PROPERTY RIGHTS, IN NO EVENT WILL EITHER PARTY BE LIABLE FOR ANY SPECIAL, INDIRECT, CONSEQUENTIAL, INCIDENTAL, OR EXEMPLARY DAMAGES, OR FOR ANY CLAIM FOR LOSS OF PROFITS, LOSS OF ANTICIPATED PROFITS, OR LOSS OF DATA, IN EACH CASE OF (I) AND (II), IN CONNECTION WITH, ARISING FROM OR IN RELATION TO THIS AGREEMENT, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE OR STRICT LIABILITY), OR ANY OTHER LEGAL OR EQUITABLE GROUNDS, AND REGARDLESS OF WHETHER SUCH DAMAGES ARE FORESEEABLE OR WHETHER SUCH PARTY IS ADVISED OF THE POSSIBILITY OR LIKELIHOOD OF SUCH DAMAGES. WITHOUT LIMITING A PARTY’S RESPONSIBILITY FOR DIRECT DAMAGES UNDER THIS AGREEMENT AND THE OTHER PARTY’S RIGHT TO CLAIM OTHER DIRECT DAMAGES, EACH PARTY AGREES THAT ITS PAYMENT OBLIGATIONS (WHETHER IN CASH, SHARES, OR OTHERWISE) UNDER THIS AGREEMENT (INCLUDING THE CONSIDERATION ADVANCE OR THE REPAYMENT OR CONVERSION THEREOF, AND ALL UPFRONT PAYMENTS, AND RECURRING PAYMENTS) (THE “PAYMENT OBLIGATIONS”), BUT NOT ANY INCREASE IN THE VALUE OF ANY SHARES, SHALL BE DEEMED TO BE DIRECT DAMAGES UNDER THIS AGREEMENT.

10.4    DAMAGES CAP. EXCEPT WITH RESPECT TO THE PAYMENT OBLIGATIONS, A CLAIM BY RINGCENTRAL FOR LICENSE FEE DAMAGES (AS DEFINED BELOW) IN ACCORDANCE WITH SECTION 10.6 IN RESPECT OF A BREACH BY AVAYA OF SECTION 6.2(e)(iii), A PARTY’S BREACH OF SECTION 2.2, SECTION 8, OR SECTION 9, RINGCENTRAL’S BREACH OF SECTION 6.2(f), SECTION 6.2(g), SECTION 6.2(h), OR THE LAST SENTENCE OF SECTION 5.3(a), OR A PARTY’S INFRINGEMENT OR MISAPPROPRIATION OF THE OTHER PARTY’S OR ITS AFFILIATES’ INTELLECTUAL PROPERTY RIGHTS, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR ANY DAMAGES OR LOSSES IN CONNECTION WITH, ARISING FROM OR IN RELATION TO THIS AGREEMENT FOR ANY AMOUNT IN EXCESS OF [***********************************].

10.5    NO LIMITATION ON FRAUD. NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, AND FOR THE AVOIDANCE OF DOUBT, NOTHING IN THIS AGREEMENT SHALL LIMIT ANY CLAIM OR RECOURSE OF ANY PARTY IN CONNECTION WITH ANY FRAUD OR WILLFUL MISCONDUCT COMMITTED BY THE OTHER PARTY OR ANY OF ITS REPRESENTATIVES.

10.6    License Fees. Notwithstanding anything to the contrary contained in this Agreement or applicable Law, Avaya and RingCentral agree that (1) if, with respect to a Subscription Fee Period, the projection for the aggregate subscription fees for such Subscription Fee Period set forth in Section 6.2(e)(iii) is greater than the actual aggregate amount of subscription fees collected and received by Avaya or its

applicable Subsidiary that are attributable to Licensed Products in such Subscription Fee Period, the existence of such difference shall be deemed to be a breach of Section 6.2(e)(iii), (2) Avaya may cure any breach of Section 6.2(e)(iii) by payment of applicable direct damages, (3) no breach of Section 6.2(e)(iii) is a material breach of this Agreement, (4) notwithstanding Section 12.7, RingCentral’s sole and exclusive remedy, and Avaya’s sole and exclusive liability, for Avaya’s breach of Section 6.2(e)(iii) with respect to a Subscription Fee Period shall be, regardless of when any claim with respect to any such breach is made, direct damages in an amount to be mutually agreed by the Parties in good faith. Such damages shall not exceed the difference between the projection in Section 6.2(e)(iii) corresponding to such Subscription Fee Period and the actual aggregate amount of subscription fees collected and received by Avaya or its applicable Subsidiary that are attributable to the Licensed Products in such Subscription Fee Period (such difference with respect to such Subscription Fee Period, the “Licensee Fee Damages”), and (5) in no event shall RingCentral be entitled any Licensee Fee Damage with respect to the same Subscription Fee Period more than once (such as, for example, if Avaya breaches Section 6.2(e)(iii) by both breaching the representation set forth in such Section and being deemed to have breached such Section pursuant to clause (1) of this Section 10.6). For the avoidance of doubt, nothing in Section 6.2(e)(iii) or this Section 10.6 shall be construed to be (x) a representation by Avaya regarding its projection of subscription fees to be collected or received by Avaya or its applicable Subsidiary that are attributable to the Licensed Products in any period of time following the Third Year Period, or (y) a damage that would otherwise be subject to the cap on damages set forth in Section 10.4.

that remains uncured for ninety (90) days from receipt of a written notice specifying in reasonable detail such material breach, or (B) by either Party if the other Party is subject of an Insolvency Event, (iii) may be terminated by RingCentral, by written notice, in the event that the restrictions set forth in Section 2.2(i) and Section 2.2(ii)(a) are determined, as set forth in an order of one or more Governmental Entities of competent jurisdiction over any Location in the Territory or a portion thereof, to be void, voidable, or otherwise unenforceable, and Section 11.2(b)(ii)(A) is satisfied with respect to a material breach of such Sections (mutatis mutandis, as if such Section 2.2(i) and Section 2.2(ii)(a) were not void, voidable, or otherwise unenforceable), and such material breach would materially and adversely affect the expected benefits to RingCentral of Section 2.2(i) and Section 2.2(ii)(a), (iv) may be terminated by RingCentral immediately, by written notice, in the event of a material breach of the Holdings Agreement by Avaya Holdings that remains uncured for ninety (90) days from Avaya Holdings’ receipt of a written notice from RingCentral specifying in reasonable detail such material breach, or (v) following the Effective Date, shall automatically terminate upon any termination of the Development Agreement or the Super Master Agent Agreement. Avaya and its Subsidiaries shall have the right to immediately terminate the license granted in Section 6.2(c), by written notice, in the event (x) that all or any portion of Section 6.2(f), Section 6.2(g), or Section 6.2(h) is determined, as set forth in an order of a Governmental Entity of competent jurisdiction, to be void, voidable, or otherwise unenforceable and RingCentral or any of its Affiliates engages in any activity that would otherwise have been prohibited by any such Section (but, for the purposes of this clause (x), not taking into account Section 2.2(e)(ii)H), or (y) of a material breach of any provision of Section 6.2 by RingCentral that remains uncured for ten (10) days from receipt of a written notice specifying in reasonable detail such material breach. In the event of any such termination of such license, Avaya’s payment obligations under Section 6.2(e) shall also terminate.

No provision of this Agreement shall survive any termination of this Agreement pursuant to Section 11.2(b)(i). Each Party acknowledges and agrees that the termination or expiration of this Agreement for any reason (other than a termination of this Agreement pursuant to Section 11.2(b)(i)) shall not release a Party from any liability or obligation that already has accrued as of the effective date of such termination or expiration, as applicable, and shall not constitute a waiver or release of, or otherwise be deemed to adversely affect, any rights, remedies, or claims which a Party may have hereunder at Law, in equity or otherwise or which may arise out of or in connection with such termination or expiration.

12.    General

12.1    Compliance with Laws. Each Party shall comply with all applicable Laws under this Agreement, the Super Master Agent Agreement, and the Development Agreement. In the United States, these may include Department of Commerce including U.S. Export Administration regulations, SEC, Environmental Protection Agency, and Department of Transportation regulations applicable to restricted or hazardous materials, and all employment and labor Laws governing that Party’s personnel. Neither Party will, in connection with this Agreement, export/re-export any technical data, process, product, or service, directly or indirectly (including the release of controlled technology to foreign nationals from controlled countries), to any country for which the United States government or any agency thereof requires an export license or other government approval without first obtaining such license.

12.2    Assignment. Prior to the Effective Date, neither Party may assign this Agreement (including by operation of Law) without the express consent of the other Party. Following the Effective Date, neither Party may assign this Agreement (including by operation of Law) without the express consent of the other Party, except that each Party may assign this Agreement, without the consent of the other Party, (i) to a U.S. corporation in connection with a corporate reorganization, provided that such Party remains responsible for all of its and such assignee’s obligations and liabilities hereunder, or (ii) to a purchaser of all or substantially all of the assets of such Party in one or more related transactions, in each case of (i) and (ii) only so long as the Development Agreement and Super Master Agent Agreement are also so assigned to such assignee or purchaser, respectively and the assignee agrees to be bound, in advance in writing, the terms of this Agreement, the Development Agreement, and the Super Master Agent Agreement. Following such an assignment, notwithstanding anything to the contrary in this Agreement, the assigning Party’s rights and obligations under this Agreement will apply only to the business (including services and products) of the assigning Party (and its Affiliates, if and as applicable) acquired by the assignee, as such business is conducted (and services and products Marketed or Sold) as of and from and after the effective date of such assignment (the “Acquired Business”), and does not apply to any other business, or any other past, current, or future services or products, of the assignee or any of its Affiliates (it being understood, for the avoidance of doubt, the assignee entity itself shall be bound by this Agreement and obligated to comply with the provisions hereof as they relate to the Acquired Business).

12.3    Notices. All notices, requests, permissions, waivers or other communications required or permitted to be given under this Agreement shall be in writing and shall be delivered by hand or sent by postage prepaid, by registered, certified or express mail or overnight courier service and shall be deemed given when so delivered by hand, by facsimile (which is confirmed), by electronic mail (which is confirmed), or if mailed, three days after mailing (one Business Day in the case of express mail or overnight courier service) to the Parties at the following addresses or facsimiles (or at such other address or facsimile for a Party as shall be specified by like notice):

12.4    Relationship of Parties. Without limiting the Super Master Agent Agreement and the arrangements thereunder, this Agreement does not create and will not be construed as creating any relationship of agency, franchise, fiduciary duty, partnership, or employment between the Parties. Accordingly, without limiting the Super Master Agent Agreement and the arrangements thereunder, neither Party will have the authority, either express or implied, to make any Contract, commitment or representation, or incur any debt or obligation on behalf of the other Party. The Parties agree to file all Tax returns (including information returns), prepare all Tax books and records, comply with applicable Tax withholding rules (if any), and pay all Taxes, in each case, for U.S. federal income and other applicable tax purposes, in accordance with the two immediately preceding sentences and in accordance with amounts payable by RingCentral to Avaya or any of its applicable Subsidiaries (as designated by Avaya) pursuant to Section 5 of this Agreement not being an allocation of gross receipts from sales of ACO to customers to Avaya or any of its Subsidiaries (as designated by Avaya) for applicable Tax purposes, with all relevant gross receipts from sales of ACO to customers recognized as gross receipts of RingCentral (or its applicable Affiliate) for applicable Tax purposes and shall not take any position contrary to the foregoing for applicable Tax purposes, in each case, unless required by a “determination” as defined in Section 1313(a) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) or otherwise required by a Tax authority in connection with the final and binding settlement of an audit.

12.5    Independent Contractors. Without limiting the Super Master Agent Agreement and the arrangements thereunder, each Party is an independent contractor for the other Party, and its employees, contractors and other personnel and representatives will not, under this Agreement, act as, nor be agents or employees of the other Party and the Parties. The Parties agree to file all Tax returns (including information returns), prepare all Tax books and records, comply with applicable Tax withholding rules (if any), and pay

all Taxes, in each case, for U.S. federal income and other applicable tax purposes, in accordance with the immediately preceding sentence and in accordance with amounts payable by RingCentral to Avaya or any of its applicable Subsidiaries (as designated by Avaya) pursuant to Section 5 of this Agreement not being an allocation of gross receipts from sales of ACO to customers to Avaya or any of its applicable Subsidiaries (as designated by Avaya) for applicable Tax purposes, with all relevant gross receipts from sales of ACO to customers recognized as gross receipts of RingCentral (or its applicable Affiliate) for applicable Tax purposes and shall not take any position contrary to the foregoing for applicable Tax purposes, in each case, unless required by a “determination” as defined in Section 1313(a) of the Code or otherwise required by a Tax authority in connection with the final and binding settlement of an audit.

12.6    Applicable Law; Exclusive Jurisdiction; Jury Waiver.

(a)    This Agreement, and all rights, obligations, claims, causes of action (whether in contract, tort or statute) or other matter that may result from, arise out of, be in connection with or relating to this Agreement, or the negotiation, administration, performance, or enforcement of this Agreement (the “Relevant Matters”), shall be governed by, and construed and enforced in accordance with, the internal Laws of the State of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflicts of Laws thereof, including its statutes of limitations. RingCentral and Avaya hereby acknowledge and agree that the United Nations Convention on Contracts for the International Sale of Goods shall not apply to this Agreement.

(b)    Each of the Parties irrevocably consents to the exclusive jurisdiction and venue of state courts located in the State of Delaware in connection with any Relevant Matter (or, only such courts decline to accept jurisdiction over a particular matter, any federal court within the State of Delaware). Each Party agrees not to commence any legal proceedings with respect to a Relevant Matter except in such Delaware state courts (or, only such courts decline to accept jurisdiction over a particular matter, any federal court within the State of Delaware). By execution and delivery of this Agreement, each Party irrevocably and unconditionally submits to the exclusive jurisdiction of such courts and to the appellate courts therefrom solely for the purposes of disputes in connection with any Relevant Matter and not as a general submission to such jurisdiction or with respect to any other dispute, matter or claim whatsoever. The Parties hereby waive any right to stay or dismiss any action or proceeding in connection with any Relevant Matter brought before the foregoing courts on the basis of (i) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason or that it or any of its property is immune from the above-described legal process, (ii) that such action or proceeding is brought in an inconvenient forum, that venue for the action or proceeding is improper or that this Agreement may not be enforced in or by such courts, or (iii) any other defense that would hinder or delay the levy, execution or collection of any amount to which any Party is entitled pursuant to any final judgment of any court having jurisdiction.

(c)    EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY AND ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE ACTIONS OF ANY PARTY IN NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT OF THIS AGREEMENT, OR ANY OTHER RELEVANT MATTER.

12.7    Specific Performance. The Parties agree that, in the event of any breach or threatened breach by a Party of this Agreement, (i) the other Party shall be entitled, without proof of actual damages (and in addition to any other remedy that may be available to it), to a decree or order of specific performance or mandamus to enforce the observance and performance of such covenant, obligation or other agreement and an injunction preventing or restraining such breach or threatened breach, and (ii) no Party shall be required

to provide or post any bond or other security or collateral in connection with any such decree, order or injunction or in connection with any related action or legal proceeding. Any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy.

12.8    Construction. For purposes of this Agreement, unless otherwise required by the context: the singular number will include the plural, and vice versa; the verb “may” indicates a legal right to perform the respective activity but does not establish a legal obligation to perform that activity; the word “will” shall be construed to have the same meaning and effect as the word “shall,” and vice versa; and the words “include,” “including” and “for example,” and variations thereof, will not be deemed to be terms of limitation, but rather will be deemed to be followed by the words “without limitation.” The word “or” is used in the inclusive sense of “and/or.” The terms “or,” “any” and “either” are not exclusive. When used herein, the phrase “to the extent” shall be deemed to be followed by the words “but only to the extent.” The word “extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase shall not mean simply “if”. The headings in this Agreement are for convenience of reference only, and will not be referred to in connection with the construction or interpretation of this Agreement. English is the official language of this Agreement. This Agreement may be translated or executed in languages other than English, but the Parties agree that the English version will control. Each Party waives any rights it may have under the Laws of any country or jurisdiction to have this Agreement written in any local language, or interpreted or superseded by local Law in those countries.

12.9    Miscellaneous. No amendment or modification of this Agreement will be valid or binding upon the Parties unless made in writing and executed by authorized representatives of each Party, except as otherwise expressly provided in this Agreement. This Agreement (together with the Super Master Agent Agreement and Development Agreement) supersedes all prior agreements and understandings, including oral representations, between the Parties (and, with respect to the Development Agreement, Avaya Management L.P., as applicable) relating to its subject matter. No waiver of any provision of this Agreement will be effective unless it is expressly stated to be a waiver and communicated to the other Party in writing by the waiving Party. Waiver of breach of any provision of this Agreement on any occasion will not be deemed a waiver of that provision or of any other provision on any other occasion, nor will such waiver affect the right of either Party to terminate this Agreement. If any provision in this Agreement is held to be invalid or unenforceable for any reason, such provision will, to the extent of such invalidity or unenforceability, be severed, but without in any way affecting the remainder of such provision or any other clause in this Agreement, and the provision will be replaced with a provision which, to the extent permitted by applicable Law, achieves the purposes intended by the invalid or unenforceable provision. This Agreement may be executed in counterparts.

12.10    Non-Solicitation. During the Term and for a period of twelve (12) months thereafter, neither Party shall (and each Party shall cause its Subsidiaries not to) directly or indirectly solicit for employment, any current or former officer or employee of the other Party or any of its Affiliates known to such Party to have performed any work in connection with or related to this Agreement, the Development Agreement, or the Super Master Agent Agreement, during and for the twelve (12) month period following such officer’s or employee’s performance of such work; provided, however, that nothing in this Section 12.10 shall prohibit either Party or its Affiliates from (i) engaging in general advertisements, solicitations or publication of employment opportunities that are not targeted at such employees or officers of the other Party, including through the assistance of third party recruiting firms, or (ii) hiring any person (A) who responds to any such advertisement, solicitation or publication, or (B) whose employment with such other Party has been terminated for at least six (6) months.

12.11    Non-Exclusive; Independent Advice; Minimum Commitment. Except as otherwise set forth in Section 2.2, this Agreement is non-exclusive, and nothing in this Agreement shall prohibit either Party from Selling any product or service or working with another product or services provider. Nothing in this Agreement shall prohibit either Party or any of its Affiliates from providing any Person with such Party’s or Affiliates’ independent advice, opinion, or belief (whether positive, negative, or otherwise) regarding any product or service (including any Avaya Service or RingCentral Service) or such Person’s solution requirements. Each Party acknowledges and agrees that the execution of this Agreement is not a guarantee by the other Party of any minimum Sales requirement or volume commitment with respect to ACO, any other RingCentral Service, or any Avaya Service.

IN WITNESS WHEREOF, intending to be bound, the Parties have executed this Agreement:
