(b) Notwithstanding anything to the contrary contained herein, if this Agreement is terminated by Buyer pursuant to Section 12.1(b), Seller agrees to return one-half of the Option Fee, upon request of Buyer, if any if such termination was based on an inability to obtain, by the Closing Date, any required approval of the proposed transactions hereunder by the Competition Board.

ARTICLE 13

INDEMNIFICATION; REMEDIES

13.1. Survival

All representations in this Agreement will survive the Closing.

13.2. Indemnification and Payment of Damages by Seller

Seller will indemnify and hold harmless Buyer for, and will pay to the Buyer, the amount of any Damages (defined below) arising from:

(a) the inaccuracy of any representation made by Seller in ARTICLE 4, ARTICLE 5 and ARTICLE 6 of this Agreement;

(b) any breach by Seller of any covenant or obligation of Seller in this Agreement;

(c) any claim by any Governmental Body, including any Turkish tax authority, that there are Taxes owed by the Companies for any period prior to the Effective Date other than Taxes accrued in the ordinary course of business or arising as a result of the transfers made pursuant to Section 8.4;

(d) any Proceeding, whether instituted before or after the Effective Date, arising from or in respect of facts, circumstances, acts, omissions or matters relating to the period prior to Closing unless a proper reserve with respect to such Proceeding is shown on the TBNG Effective Date Balance Sheet or the PTI Effective Date Balance Sheet, as applicable; or

(e) any Liability or claim arising from or in respect of any facts, circumstances, acts, omissions or matters relating to the period prior to the Effective Date including claims of, or Liability to, current or former employees other than those shown on the TBNG Effective Date Balance Sheet or the PTI Effective Date Balance Sheet.

For purposes of this Agreement the term “Damages” shall mean all costs, losses (including diminution in value), liabilities, deficiencies, claims and expenses (which include interest, penalties, cost of mitigation, attorney’s fees and amounts paid in investigation, defense or settlement of any claim or Liability).

13.3. Indemnification and Payment of Damages by Buyer

(a) Buyer will indemnify and hold harmless Seller for, and will pay to Seller the amount of any Damages arising, directly or indirectly, from or in connection with (a) any breach of any representation or warranty made by Buyer in this Agreement or in any certificate delivered by Buyer pursuant to this Agreement, or (b) any breach by Buyer of any covenant or obligation of Buyer in this Agreement. Buyer further indemnifies and holds harmless Seller from all claims relating to the Companies that may arise from operations after the Closing Date.

(b) Unless a claim pursuant to this Article 13 has been made on or prior to expiration of one year from the Closing Date, the TA Stock held in escrow will be released by the Escrow Agent pursuant to the Escrow Agreement.

13.4. Time Limitation

If the Closing occurs, neither party will have any liability (for indemnification or otherwise) with respect to any representation or warranty, or covenant or obligation to be performed and complied unless on or before the expiration of three year from the Closing Date, the indemnified party notifies the other party of a claim specifying the factual basis of that claim in reasonable detail to the extent then known by the indemnified party; provided, however, the representations, warranties, covenants and obligations regarding (i) taxes shall continue until the applicable statute of limitations and (ii) due authorization, valid formation, valid existence and legal compliance shall continue indefinitely.

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

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

A claim for indemnification for any matter not involving a third-party claim may be asserted by notice to the party from whom indemnification is sought.

13.7. Maintenance of Minimum Net Worth Once the TA Stock has been returned to Seller under the Escrow Agreement, Seller agrees to maintain a minimum net worth of at least Ten Million and No/100 Dollars ($10,000,00.00) until the later to occur of (i) three years from the Closing Date and (ii) the date on which the applicable statute of limitations bars any claim for Taxes.

13.8. Exclusive Remedy

Seller and Buyer acknowledge and agree that their respective sole and exclusive remedy with respect to any and all claims relating to the subject matter of this Agreement shall be pursuant to the indemnification provisions set forth in this ARTICLE 13, subject to the limitations contained in Sections 13.4 and under the provisions of the Escrow Agreement.

ARTICLE 14

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

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.

ARTICLE 15

GENERAL PROVISIONS

15.1. Expenses

Each party to this Agreement will bear its respective expenses incurred in connection with the preparation, execution, and performance of this Agreement, including all fees and expenses of agents, representatives, counsel, and accountants. In the event of termination of this Agreement, the obligation of each party to pay its own expenses will be subject to any rights of such party to seek recovery of such expenses arising from a breach of this Agreement by another party.

15.2. Public Announcements

Neither Buyer nor Seller will issue any public announcement or similar publicity with respect to this Agreement without the prior written consent of the other party; provided, however, that either Buyer or Seller may make any public disclosure they believe in good faith, based upon advice of counsel, is required by any Legal Requirement (in which case the disclosing party will advise the other party prior to making the disclosure). Seller and Buyer will consult with each other concerning the means by which the Companies’ employees, customers, and suppliers and others having dealings with the Companies will be informed of the transactions contemplated hereby, and Buyer will have the right to be present for any such communication.

15.3. Confidentiality

Between the date of this Agreement and the Closing Date, Buyer and Seller will maintain in confidence, and will cause the directors, officers, employees, agents, and advisors of Buyer and the Companies to maintain in confidence, any written, oral, or other information obtained in confidence from another party or the Companies in connection with this Agreement or the transactions contemplated hereby, unless (a) such information is already known to such party or to others not bound by a duty of confidentiality or such information becomes publicly available through no fault of such party, (b) the use of such information is necessary or appropriate in making any filing or obtaining any consent or approval required for the consummation of the transactions contemplated hereby, or (c) the furnishing or use of such information is required by any Legal Requirement. Notwithstanding the foregoing, Buyer an announcement may be made to employees of the Companies regarding this Agreement and the transactions contemplated hereby.

If the transactions contemplated hereby are not consummated, each party will return or destroy as much of such written information as the other party may reasonably request.

15.4. Notices

All notices, consents, waivers, and other communications under this Agreement must be in writing and will be deemed to have been duly given when (a) delivered by hand (with written confirmation of receipt), (b) sent by facsimile (with written confirmation of receipt) or electronic mail, provided that a copy is mailed by registered mail, return receipt requested, or (c) when received by the addressee, if sent by a nationally recognized overnight delivery service (receipt requested), in each case to the appropriate addresses and facsimile numbers set forth below (or to such other addresses and facsimile numbers as a party may designate by notice to the other parties). A copy of any notice, consent, waiver or other communications shall also be sent by electronic mail to the recipient’s address set forth below; provided, however, that the failure to comply with this requirement shall not affect the effectiveness of such notice, consent, waiver or other communication if the other provisions of this Section 15.4 are followed.

15.10. Severability

If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable.
