(c) at any time from the date of this Agreement, enter into any agreement or arrangement or binding understanding with any member of Voicebox’s Sellers’ Group with financial repercussions on, or leading to liability on the part of, any party to such agreement or arrangement (whether at the time such agreement or arrangement or binding understanding is entered into or in the future).

9.5 Nothing contained in clause 9.4 shall prevent any of the Management Sellers from being employed or engaged by any Target Company or, for so long as they remain employed or engaged by any Target Company, restrict them from duly carrying out their duties as employees, consultants, service providers and/or directors of any Target Company.

9.6 The undertakings in clauses 9.3 and 9.4 are intended for the benefit of the Purchaser and the Purchaser Group and apply to actions carried out by the applicable Seller, or, with respect to clause 9.3, Voicebox’s Sellers’ Group, in any capacity whatsoever and whether directly or indirectly, on such Seller’s or such member of its Sellers’ Group’s own behalf, on behalf of any other person or jointly with any other person.

9.7 The undertakings contained in clauses 9.3 and 9.4 are reasonable and necessary for the protection of the Purchaser’s legitimate interests in the goodwill of the Target Group and to confer upon the Purchaser the full benefit of the business and goodwill of the Target Group, and shall be construed as separate and independent undertakings. If any such undertaking is held to be void or

Page 26

Project Beaker - SPA

unenforceable, the validity of the remaining undertakings shall not be affected, and if any such undertaking is found to be void or unenforceable but would be valid and enforceable if some part or parts of the undertaking were deleted, such undertaking shall apply with such modification as may be necessary to make it valid and enforceable.

9.8 Without prejudice to clause 9.7, if any undertaking in this clause 9 is found by any court or other competent authority to be void or unenforceable, the Parties shall negotiate in good faith to replace such void or unenforceable undertaking with a valid provision which, as far as possible, has the same commercial effect as the provision which it replaces.

9.9 Save in the case of fraud or fraudulent misrepresentation, each Seller undertakes to the Purchaser that it:

4.has no rights against (and waives any rights it may have against); and

5.shall not make any claim against (and waives any claim it may have against),

any Target Company or any of its directors or officers (a Covered Person) or its employees or consultants provided that this clause shall (i) not have any effect on any rights or claims that any of the Management Sellers could have against any Target Company in connection with or arising out of the relationship that exists between such Target Company and Management Seller under such Management Seller’s consultancy agreement or employment contract (as applicable), and (ii) not apply to claims against a member of the Purchaser Group for breach of this Agreement.

Directors

9.10 Following Closing, the Purchaser shall ensure that any indemnity and/or immunity provisions contained in the memorandum and articles of association (or similar constitutional documents) of each Target Company of which a Covered Person was an officer or director immediately prior to Closing are not amended, repealed or modified in any manner that would affect the rights of any such Covered Person in an adverse manner.

9.11 For six years from Closing, the Purchaser shall ensure that each Target Company maintains in force such “run-off” directors’ and officers’ liability insurance policies as will enable each Covered Person to, subject to the terms of such insurance policies, make claims arising out of any matter, cause or event occurring before Closing under those policies on terms and conditions that are no less advantageous to such Covered Person than the terms and conditions of cover for such Covered Person contained in the directors’ and officers’ liability insurance policies maintained by the Target Companies as at the date of this Agreement.

9.12 The Purchaser shall:

(a) procure that the directors, managers and members of the executive committee (or local equivalents) of Voxbone who hold office at Closing or held office prior to Closing (together, Voice Directors) are granted

Page 27

unconditional and irrevocable discharge for the performance of their duties as director, manager or member of the executive committee (or local equivalents) of Voxbone up until Closing, at the next relevant annual shareholders’ meetings (or other relevant corporate body meeting) of Voxbone; and

(b) not initiate legal proceedings against any Voice Director (or its permanent representative) in connection with the Proposed Transaction (save in the case of fraud or fraudulent misrepresentation or as may be agreed between the Purchaser on one hand and any Voice Director on the other hand).

10.Sellers Warranties

10.1 Each of the Sellers warrants to the Purchaser that each of the statements set out in Schedule 1 (the Sellers Warranties), in so far as it relates to that individual Seller, is true and accurate on the date of this Agreement, and shall be true and accurate on the Closing Date by reference to the facts and circumstances then existing, subject to the provisions of this Agreement (including the limitations set out in Schedule 2 and in clause 13).

10.2 The Purchaser acknowledges and agrees that:

(a) other than the warranties given by the Management Sellers in the Management Warranty Deed, the Sellers Warranties are the only warranties of any kind given by or on behalf of the Sellers or any other member of a Sellers’ Group or their Representatives (and on which the Purchaser may rely in entering into this Agreement);

(b) no other representation, warranty, statement, estimate, forecast, opinion, projection or promise made by or on behalf of any Seller, any member of any Sellers’ Group, their Representatives or the Target Companies may form the basis of, or be pleaded in connection with, any claim by any member of the Purchaser Group under or in connection with any Transaction Document; and

(c) without prejudice to the generality of the foregoing, the Sellers do not give any warranty or make any representation as to the accuracy of any forecasts, estimates, projections, statements of intent or opinion provided to any member of the Purchaser Group or its Representatives (including in the Data Rooms).

10.3 The Sellers acknowledge that the Purchaser is entering into this Agreement on the basis of and in express reliance on the Sellers Warranties.

11.Warranty Insurance Policy

11.1 The Purchaser acknowledges and agrees that:

Page 28

Project Beaker - SPA

pursuant to or in connection with this Agreement beyond the express terms of this Agreement (including the limitations set out in Schedule 2 and in clause 13);

(b) at the date of this Agreement, it shall deliver to the Sellers’ Representative evidence that (i) the Warranty Insurance Policy has been duly and validly entered into and the coverage under the Warranty Insurance Policy is effective as at the date of this Agreement, and (ii) the Warranty Insurance Policy includes an express waiver from the W&I Insurer of any rights of subrogation that it may have against the Sellers (except in the case of fraud or fraudulent misrepresentation by a Seller, but in respect of such Seller only);

(c) it shall not waive or agree to amend and shall procure that there is no waiver or amendment of the provisions of the Warranty Insurance Policy (including of the provisions pursuant to which the W&I Insurer waives any rights of subrogation it may have against (any of) the Sellers), without the prior written consent of the Sellers (which consent shall not be unreasonably withheld, conditioned or delayed); and

(d) it shall not novate or otherwise assign its rights under the Warranty Insurance Policy (or do anything which has a similar effect) except, to the extent permitted under the Warranty Insurance Policy, to a member of the Purchaser Group, or do anything which causes any right under the Warranty Insurance Policy not to have full force or effect.

11.2 If there is any conflict or inconsistency between this clause 11 and any other provision of any Transaction Document or the Warranty Insurance Policy, this clause 11 shall prevail.

12.Purchaser warranties

The Purchaser warrants to each and all of the Sellers that each of the statements set out in Schedule 3 is true and accurate on the date of this Agreement, and shall be true and accurate on the Closing Date (by reference to the facts and circumstances then existing).

13.Allocation of the Sellers' liability

13.1 The Purchaser expressly acknowledges and agrees that the liability of each Seller under or in connection with any Transaction Document, shall be several (and not joint or joint and several). The failure by a Seller to perform any of its obligations shall not affect the obligations of the other Sellers towards any other Party, nor shall a Seller be liable for the failure of any other Seller to perform such obligations.

13.2 Each of the Sellers makes the Sellers Warranties (insofar as applicable to it) individually for itself and with respect to the Securities sold by it and the LNs held by it, and the other Sellers cannot be held liable for a breach of such Sellers Warranties.

13.3 The liability of each Seller for each Purchaser Claim (excluding claims for breach of the Sellers Warranties) shall be limited to such Seller’s Liability

Page 29

Project Beaker - SPA

Percentage of such Purchaser Claim (excluding claims for breach of the Sellers Warranties), or where fewer than all the Sellers are liable in respect of such Purchaser Claim (excluding claims for breach of the Sellers Warranties), such Sellers shall be severally and proportionately liable hereunder in the respective proportions that each such Seller’s Liability Percentage bears to the aggregate Liability Percentages of all such Sellers who are liable in respect of such Purchaser Claim (excluding claims for breach of the Sellers Warranties).

13.4 In each case, the liability of the Sellers shall be subject to the limitations set out in Schedule 2, as applicable.

14.Announcements

14.1 Notwithstanding clause 15, neither the Sellers nor the Purchaser (or any member of the Purchaser Group) shall make any announcement in connection with the existence or subject matter of the Transaction Documents or the Proposed Transaction, without the prior written approval of the other Parties on the making of an announcement, its timing and its content (which shall not be unreasonably withheld, conditioned or delayed).

16.7 This Agreement shall be binding on and inure for the benefit of the successors of each of the Parties to this Agreement.

(c) the only right or remedy of a Party in relation to any statement, representation, warranty or undertaking set out in this Agreement or any other Transaction Document shall be for breach of this Agreement or the relevant Transaction Document and/or injunction or other equitable relief to the exclusion of all other rights and remedies (including those in tort or arising under statute); and

(d) except for any liability in respect of a breach of this Agreement or any other Transaction Document, no Party (or any of its Connected Persons or Representatives) shall owe any duty of care or have any liability in tort or otherwise to the other parties (or their respective Connected Persons or Representatives) in relation to the Proposed Transaction,

provided that this clause 16.16 shall not exclude any liability for (or remedy in respect of) fraud or fraudulent misrepresentation. Each Party agrees to the terms of this clause 16.16 on its own behalf and as agent for each of its Connected Persons and Representatives.

Waivers, variations and invalidity

16.17 Except as expressly provided in this Agreement, no failure or delay by any Party in exercising any right or remedy relating to this Agreement shall affect or operate as a waiver or variation of that right or remedy, or preclude its exercise at any subsequent time. No single or partial exercise of any such right or remedy shall preclude any further exercise of it or the exercise of any other remedy.

16.18 A waiver of any right or remedy relating to this Agreement shall only be effective if given in writing and shall not be deemed a waiver of any subsequent breach or default.

16.19 No amendment of this Agreement shall be valid, unless it is in writing and duly executed on behalf of the Sellers’ Representative and the Purchaser. Unless expressly agreed, no amendment shall constitute a general waiver of any provision of this Agreement, nor shall it affect any rights or obligations under or pursuant to this Agreement which have already accrued up to the date of amendment and the rights and obligations under or pursuant to this Agreement shall remain in full force and effect except and only to the extent that they are amended.

16.20 Each of the provisions of this Agreement is severable. If any such provision is or becomes illegal, invalid or unenforceable under the Law of any jurisdiction, the Parties shall use all reasonable efforts to replace it with a valid and enforceable substitute provision the effect of which is as close to its intended effect as possible.

Withholdings and set-off

16.22 All sums payable by the Parties under this Agreement or any of the Transaction Documents or for breach of any of the provisions of this Agreement or any of the Transaction Documents shall be paid free and clear of all deductions or withholdings whatsoever, save only as provided in this Agreement or as required by applicable Law.

16.23 If any Party is required by Law to make a deduction or withholding in respect of any sum payable under this Agreement (other than the payment of the Initial Consideration under clause 3.2, the payment of any Purchase Price Adjustment, the payment of the Holdback Amount or the repayment of the Employee Loans), it shall, at the same time as the sum which is the subject of the deduction or withholding is payable, make a payment to the other Party of such additional amount as shall be required to ensure that the net amount received by that other Party will equal the full amount which would have been received by them had no such deduction or withholding been required to be made. Any Party that determines that an amount is required to be deducted and withheld by Law, shall provide the payee with (i) commercially reasonable notice of such Party’s intent to deduct and withhold, which shall include a copy of the calculation of the amount to be deducted and withheld and (ii) a reasonable opportunity for the payee to provide forms or other evidence that would exempt such amounts from withholding (or reduce such withholding).

16.24 If any sum paid by any Party (other than the payment of the Initial Consideration under clause 3.2, the payment of any Purchase Price Adjustment, the payment of the Holdback Amount or the repayment of the Employee Loans) is required by Law to be brought into charge to Tax by the other Party (or would be but for any Relief) then, except in relation to interest, the paying Party shall pay such additional amount as shall be required to ensure that the total amount paid, less the Tax chargeable on such amount (or that would be chargeable but for such Relief), is equal to the amount that would otherwise be payable.

16.25 Each Party waives and relinquishes any right of set-off or counterclaim, deduction or retention which it might otherwise have out of any payments which it may be obliged to make (or procure to be made) to any other Party pursuant to this Agreement or otherwise.

Counterparts

16.26 This Agreement may be executed in any number of counterparts, and by each Party on separate counterparts.

Conflict with other agreements

16.31 If there is any conflict between the terms of this Agreement and any other agreement (including, for the avoidance of doubt, the Shareholders’ Agreement), this Agreement shall prevail (as between the parties to this Agreement and as between any of their Affiliates) unless the Parties to this Agreement:

(a) are also parties to that other agreement and such other agreement expressly states that it overrides this Agreement in the relevant respect; or

(b) expressly agree in writing that such other agreement shall override this Agreement in that respect.

16.32 Each of the Sellers acknowledges and agrees, for the benefit of each other Seller that the entry into the Transaction Documents and the completion of the Proposed Transaction is approved for all purposes under the Shareholders’ Agreement and the Articles of Association, and no Seller shall assert any claim against any other Seller or a Target Company pursuant to the Shareholders’ Agreement or Articles of Association in respect of any action contemplated by the Transaction Documents.

16.33 To the extent permitted by Law, where any provision of this Agreement conflicts with any of the Articles of Association, each of the relevant Sellers undertakes to exercise its voting rights in respect of such Target Company to procure that the relevant Articles of Association are amended so as to ensure that they are consistent with the terms of this Agreement.

1.Net Working Capital shall be prepared based on the general ledger of the Target Group on a consolidated basis as at the Effective Time, subject to the Accounting Principles.

2.Consideration shall only be given to information, facts, circumstances, and events as of the Effective Time, provided, that, notwithstanding any requirements of IFRS, all effects arising from the consummation of the transactions contemplated by the Agreement and the other Transaction Documents and occurring within the period from the Effective Time until the Closing Statement is prepared, including the effects of any purchase accounting, as well as any act, decision, change in circumstance, development or event arising or occurring after the Effective Time, including but not limited to, transactions outside the ordinary course of business that are taken by the Purchaser or at the direction of the Purchaser or any of its Affiliates, will be disregarded for the purpose of making any determination as of the Effective Time.

3.Net Working Capital shall be determined on the basis that each of the Target Companies is a going concern and, except as required elsewhere in this Agreement or paragraph 2 above, shall exclude the effect of change of control or ownership of the Target Companies and will not take into account the effects of any post-Closing reorganisations or the post-Closing intentions or obligations of the Purchaser.

Page 59

AMS6540051 168372-0004

Confidential

Project Beaker - SPA

assumptions and estimation methodologies would justify such a provision, accrual, increase or decrease.

6.No liabilities shall be reflected in Net Working Capital pertaining to losses or liabilities that are recoverable from other parties, whether or not such losses or liabilities have been recovered as of the Effective Time. No assets should be reflected in Net Working Capital pertaining to settlements, refunds or assets that, in each case, are payable to other parties as of the Effective Time.

(a) Cash;

(b) Debt; and

8.For the purposes of determining Net Working Capital, the trade receivable reserves shall be calculated in a manner consistent with the financial reporting processes and accounting principles, practices, procedures, policies, and methods, classifications, judgments, assumptions, techniques, elections, inclusions, exclusions and valuation and estimation methodologies used in the illustrative calculation of Net Working Capital set out in Part B of this Schedule 6.

9.No items may be included more than once in the Closing Statement.
