Such interest will be payable at the same time as the payment to which it relates.

4.4 Tax Consequences of Payments. For all Tax purposes and to the extent permitted by applicable Tax Law, the parties hereto shall treat any payment made pursuant to this Agreement as a capital contribution or a distribution, as the case may be, immediately prior to the Distribution. If the receipt or accrual of any indemnity payment under this Agreement causes, directly or indirectly, an increase in the taxable income of the recipient under one or more applicable Tax Laws, such payment shall be increased so that, after the payment of any Taxes with respect to the payment, the recipient thereof shall have realized the same net amount it would have realized had the payment not resulted in taxable income. To the extent that Taxes for which any party hereto (the indemnifying party) is required to pay another party (the indemnified party) pursuant to this Agreement may be deducted or credited in

determining the amount of any other Taxes required to be paid by the indemnified party (for example, state Taxes which are permitted to be deducted in determining federal Taxes), the amount of any payment made to the indemnified party by the indemnifying party shall be decreased by taking into account any resulting reduction in other Taxes of the indemnified party. If such a reduction in Taxes of the indemnified party occurs following the payment made to the indemnified Party with respect to the relevant indemnified Taxes, the indemnified party shall promptly repay the indemnifying party the amount of such reduction when actually realized. If the Tax benefit arising from the foregoing reduction of Taxes described in this Section 4.4 is subsequently decreased or eliminated, then the indemnifying party shall promptly pay the indemnified party the amount of the decrease in such Tax benefit.

SECTION 5. Assistance and Cooperation.

5.1 Cooperation. In addition to the obligations enumerated in Sections 3.3 and 7.7, Bandwidth and Republic Wireless will cooperate (and cause their respective Subsidiaries and Affiliates to cooperate) with each other and with each other’s agents, including accounting firms and legal counsel, in connection with Tax matters, including provision of relevant documents and information in their possession and making available to each other, as reasonably requested and available, personnel (including officers, directors, employees and agents of the parties or their respective Subsidiaries or Affiliates) responsible for preparing, maintaining, and interpreting information and documents relevant to Taxes, and personnel reasonably required as witnesses or for purposes of providing information or documents in connection with any administrative or judicial proceedings relating to Taxes. In addition to the foregoing, on or before December 31, 2017, Bandwidth will deliver to Republic Wireless the Earnings and Profits Analysis / Report, which will be subject to Republic Wireless’ approval, which will not be unreasonably withheld; upon approval, Republic Wireless will reimburse Bandwidth for Bandwidth’s reasonable out-of-pocket costs incurred in connection with the preparation of the Earnings and Profits Analysis / Report, which will not exceed $25,000. Republic Wireless will provide to Bandwidth such assistance and information as Bandwidth may reasonably request in connection with the preparation of any Combined Return or Separate Return regarding any applicable refunds, credits or offsets.

SECTION 6. Tax Records.

6.1 Retention of Tax Records. Each of Bandwidth and Republic Wireless shall preserve, and shall cause their respective Subsidiaries to preserve, all Tax Records that are in their possession, and that could affect the liability of any member of the other Group for Taxes, for as long as the contents thereof may become material in the administration of any matter under applicable Tax Law, but in any event until the later of (x) the expiration of any applicable statutes of limitation, as extended, and (y) seven years after the Distribution Date.

6.3 Confidentiality. Each party hereby agrees that it will hold, and shall use its reasonable best efforts to cause its officers, directors, employees, accountants, counsel, consultants, advisors and agents to hold, in confidence all records and information prepared and shared by and among the parties in carrying out the intent of this Agreement, except as may otherwise be necessary in connection with the filing of Tax Returns or any administrative or judicial proceedings relating to Taxes or unless disclosure is compelled by a governmental authority. Information and documents of one party (the “Disclosing Party”) shall not be deemed to be confidential for purposes of this Section 6.3 to the extent such information or document (i) is previously known to or in the possession of the other party or parties (the “Receiving Party”) and is not otherwise subject to a requirement to be kept confidential, (ii) becomes publicly available by means other than unauthorized disclosure under this Agreement by the Receiving Party or (iii) is received from a third party without, to the knowledge of the Receiving Party after reasonable diligence, a duty of confidentiality owed to the Disclosing Party.

6.4 Delivery of Tax Records. Within five Business Days after receiving notification from Republic Wireless requesting any applicable Tax Records described below which are in the possession of a member of the Bandwidth Group, Bandwidth shall provide to Republic Wireless (to the extent not previously provided or held by any member of the Republic Wireless Group on the Distribution Date) copies of (i) the Separate Returns of any member of the Republic Wireless Group, (ii) the relevant portions of any other Tax Returns with respect to any member of the Republic Wireless Group, and (iii) other existing Tax Records (or the relevant portions thereof) reasonably necessary to prepare and file any Tax Returns of, or with respect to, the members of the Republic Wireless Group, or to defend or contest Tax matters relevant to the members of the Republic Wireless Group, including in each case, all Tax Records related to Tax attributes of the members of the Republic Wireless Group and any and all communications or agreements with, or rulings by, any Tax Authority with respect to any member of the Republic Wireless Group.

Unless and until there has been a Final Determination to the contrary, each party agrees not to take any position on any Tax Return, in connection with any Tax Contest, or otherwise for Tax purposes (in each case, excluding any position taken for financial accounting purposes) that is inconsistent with the Tax Opinion.

7.5 Notices of Tax Contests (Other than Joint Claims). Each Company shall provide prompt notice to the other Company of any pending or threatened Tax audit, assessment or proceeding or other Tax Contest of which it becomes aware relating to Taxes for which it is or may be indemnified by such other Company hereunder (other than any Transaction Taxes which shall be governed by Section 7.8). Such notice shall contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Tax Authority in respect of any such matters; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except, and only to the extent that, the indemnifying Company shall have been actually prejudiced as a result of such failure. Thereafter, the indemnified Company shall deliver to the indemnifying Company such additional information with respect to such Tax Contest in its possession that the indemnifying Company may reasonably request.

7.6 Control of Tax Contests (Other than Joint Claims).

(a) General Rule. Except as provided in Sections 7.6(b) and 7.8, each Company (or the appropriate member of its Group) shall have full responsibility, control and discretion in handling, defending, settling or contesting any Tax Contest involving a Tax reported (or that, it is asserted, should have been reported) on a Tax Return for which such Company is responsible for preparing and filing (or causing to be prepared and filed) pursuant to Section 3 of this Agreement.

(b) Non-Preparer Participation Rights. With respect to a Tax Contest (other than with respect to a Joint Claim) of any Tax Return which could result in a Tax liability for which the Non-Preparer may be liable under this Agreement, (i) the Non-Preparer shall, at its own cost and expense, be entitled to participate in such Tax Contest, (ii) the Preparer shall keep the Non-Preparer updated and informed, and shall consult with the Non-Preparer, (iii) the Preparer shall act in good faith with a view to the merits in connection with the Tax Contest, and (iv) the Preparer shall not settle or compromise such Tax Contest without the prior written consent of the Non-Preparer (which consent shall not be unreasonably withheld or delayed) if the settlement or compromise could have a more than de minimis impact on the Non-Preparer or its Affiliates.

7.7 Cooperation. The parties shall provide each other with all information relating to a Tax Contest which is needed by the other party or parties to handle, participate in, defend, settle or contest the Tax Contest. At the request of any party, the other parties shall take any action (e.g., executing a power of attorney) that is reasonably necessary in order for the requesting party to exercise its rights under this Agreement in respect of a Tax Contest. Republic Wireless shall assist Bandwidth, and Bandwidth shall assist Republic Wireless, in taking any remedial actions that are necessary or desirable to minimize the effects of any adjustment made by a Tax Authority. The indemnifying party or parties shall reimburse the indemnified party or parties for any reasonable out-of-pocket costs and expenses incurred in complying with this Section 7.7.

7.8 Joint Claims. Each Company shall promptly give notice to the other Company of any pending or threatened Tax Contest, claim, action, suit, investigation or proceeding brought by a third party relating to any Transaction Taxes or Transaction Tax-Related Losses for which such Company is or may be indemnified by the other Company under this Section 7 (each, a “Joint Claim”). Such notice shall contain (i) factual information (to the extent known) describing any asserted Tax liability or other claim in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Tax Authority or third party relating to the Joint Claim, and (ii) the amount of the Joint Claim. Such notice shall be given within a reasonable period of time after notice thereof was received by such Company, but any failure to give timely notice shall not affect the indemnities given hereunder except, and only to the extent that, the indemnifying Company shall have been actually prejudiced as a result of such failure. Thereafter, each Company shall deliver to the other Company such additional information with respect to such Joint Claim in its possession that the other Company may reasonably

request. Bandwidth and Republic Wireless will have the right to jointly control the defense, compromise or settlement of any Joint Claim. No indemnified Company shall settle or compromise or consent to entry of any judgment with respect to any such Joint Claim without the prior written consent of the indemnifying Company, which consent may be withheld in the indemnifying Company’s sole discretion. No indemnifying Company shall settle or compromise or consent to entry of any judgment with respect to any such Joint Claim without the prior written consent of the indemnified Company, which consent may not be unreasonably withheld or delayed.

ANNEX 1

Xxxxxxxxx.xxx Inc. (“Bandwidth”) intends to claim a Research and Development (“R&D”) tax credit under Internal Revenue Code (“IRC”) Section 41 for its tax year 2016. Accordingly, Bandwidth is seeking to exclude qualified research expenses (“QREs”) from its base period generated by Republic Wireless (“Republic”) during the tax years 2013-2015, due to the spin-off of Republic from Bandwidth in November 2016.

Republic will be required under IRC Sec. 41(c)(5)(A) to report its respective QREs for this period as part of its base period. IRC Sec. 41(f)(3)(B) requires Bandwidth provide a letter to Republic in order to remove the Republic QREs from its base period. Accordingly, Table 1 below summarizes the QREs generated by Republic during the base period, which must be included in Republic’s base period calculation.

Thank you for your assistance in this matter.

*Total*		2,298,657		3,321,741		3,701,853		9,322,251

Republic Wireless (“Republic”) would like to inquire as to whether Xxxxxxxxx.xxx Inc. (“Bandwidth”) claimed a Research and Development (“R&D”) Tax Credit under Internal Revenue Code (“IRC”) Section 41 for tax years 2013 through 2015. If Bandwidth did claim an IRC Section 41 R&D Credit, the question arises as to whether the business unit Republic, which was spun-off in November of 2016, had any qualified research expenses (“QREs”) that were included in the Bandwidth R&D Credit calculation.

Republic intends to claim an R&D tax credit under Internal Revenue Code section 41 for its tax year 2016. We respectfully request that Bandwidth provide the Republic QREs from the years 2013 through 2015. Republic will be required under IRC Sec. 41(c)(5)(A) to report its respective QRE’s for this period as part of its base period. IRC Sec. 41(f)(3)(B) requires that Bandwidth provide a letter to Republic in order to remove the Republic QREs from its base period.

Thank you for your assistance with this request.
