13.5. Procedure for Indemnification  Third Party Claims

(a) Promptly after receipt by an indemnified party under Section 13.2 or Section 13.3 of notice of the commencement of any
Proceeding against it, such indemnified party will, if a claim is to be made against an indemnifying party under such Section, give notice to the indemnifying party of the commencement of such claim, but the failure to notify the indemnifying party
will not relieve the indemnifying party of any liability that it may have to any indemnified party, except to the extent that the indemnifying party demonstrates that the defense of such action is prejudiced by the indemnifying partys failure
to give such notice.

(b) If any Proceeding referred to in Section 13.5 is brought against an indemnified party and it
gives notice to the indemnifying party of the commencement of such Proceeding, the indemnifying party will, unless the claim involves Taxes, be entitled to participate in such Proceeding and, to the extent that it wishes (unless (i) the
indemnifying party is also a party to such Proceeding and the indemnified party determines in good faith that joint representation would be inappropriate, or (ii) the indemnifying party fails to provide reasonable assurance to the indemnified
party of its financial capacity to defend such Proceeding and provide indemnification with respect to such Proceeding), to assume the defense of such Proceeding with counsel satisfactory to the indemnified party and, after notice from the
indemnifying party to the indemnified party of its election to assume the defense of such Proceeding, the indemnifying party will not, as long as it diligently conducts such defense, be liable to the indemnified party under this ARTICLE 13 for any
fees of other counsel or any other expenses with respect to the defense of such Proceeding, in each case subsequently incurred by the indemnified party in connection with the defense of such Proceeding, other than reasonable costs of investigation.
If the indemnifying party assumes the defense of a Proceeding, (i) it will be conclusively established for purposes of this Agreement that the claims made in that Proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims may be effected by the indemnifying party without the indemnified partys consent unless (A) there is no finding or admission of any violation of Legal Requirements or any violation of the rights of
any Person and no effect on any other claims that may be made against the indemnified party, and (B) the sole relief provided is monetary damages that are paid in full by the indemnifying party; and (iii) the indemnified party will have no
liability with respect to any compromise or settlement of such claims effected without its consent. If notice is given to an indemnifying party of the commencement of any Proceeding and the indemnifying party does not, within ten days after the
indemnified partys notice is given, give notice to the indemnified party of its election to assume the defense of such Proceeding, the indemnifying party will be bound by any determination made in such Proceeding or any compromise or
settlement effected by the indemnified party. Each indemnified party hereby grants to the indemnifying party, to the extent permitted by law or by the terms of the indemnified partys insurance policies then in force, a right of subrogation to
proceed against the particular third party or parties in question, and seek to recover therefrom any amounts to which such indemnifying party may be lawfully entitled.

(c) Notwithstanding the foregoing, if an indemnified party determines in good faith that there is a reasonable probability that a Proceeding may adversely affect it or its affiliates other than as a
result of monetary damages for which it would be entitled to indemnification under this Agreement, the indemnified party may, by notice to the indemnifying party, assume the exclusive right to defend, compromise, or settle such Proceeding, but the
indemnifying party will



43



---

not be bound by any determination of a Proceeding so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld).

(d) Seller and Buyer hereby consent to the non-exclusive jurisdiction of any court in which a Proceeding is brought against any
Indemnified Person for purposes of any claim that an Indemnified Person may have under this Agreement with respect to such Proceeding or the matters alleged therein, and agree that process may be served on Seller with respect to such a claim
anywhere in the world.

13.6. Procedure for Indemnification  Other Claims

ASSIGNMENT

14.1. Assignment of Agreement

Seller acknowledges and agrees that Buyer may assign its rights to acquire the TBNG Shares and/or the PTI Shares to a third party who is either (i) an affiliate of the Buyer or (ii) a newly
formed entity for which the Buyer (or its affiliates) have engaged in significant formation and financing activities, the purpose of which entity is to acquire the TBNG Shares and/or the PTI Shares. Seller agrees that Buyer may, in its sole
discretion, assign its rights hereunder to purchase the TBNG Shares or the PTI Shares or both. Prior to Closing Buyer will notify Seller of any such assignment and the identity of such assignee(s). Upon such notice any such assignee shall be deemed
a third party beneficiary of this Agreement with full independent rights to (a) rely on the representations, warranties and covenants contained herein and (b) enforce all rights and obligations hereunder, as to the TBNG Shares or PTI
Shares assigned to such assignee. From and after the date of any notice regarding an assignee, the term Buyer shall be deemed to include TransAtlantic Worldwide Ltd. and any such assignee(s). Any such assignment shall not relieve Buyer
of any of its obligations hereunder.

14.2. Separate Agreement In connection with any notice to Seller of the assignment by Buyer of
its rights hereunder to purchase the TBNG Shares or the PTI Shares or both, Seller agrees to



44



---

coordinate with Buyer and any such assignee in the preparation and execution of a separate stock purchase agreement relating specifically to such TBNG Shares and/or PTI Shares, as appropriate.
Any separate stock purchase agreement relating to the TBNG Shares or PTI Shares, upon execution, will supersede the obligations of Seller and Buyer under this Agreement as to such shares. Notwithstanding anything to the contrary contained herein,
Seller shall not be obligated to execute any such new stock purchase agreement unless (i) such agreement, along with any remaining rights and obligations under this Agreement, contain, in the aggregate, the identical rights, obligations and
covenants contained herein and (ii) Buyer unconditionally guarantees the payment and performance of the assignee.
