(d) Each Seller and the Purchaser agrees that, in the event that any consent, approval or authorization necessary or desirable to preserve for the Company or any Subsidiary any right or benefit under any lease, license, contract, commitment or other agreement or arrangement to which the Company or any Subsidiary is a party is not obtained prior to the Closing, each Seller will, subsequent to the Closing, cooperate with the Purchaser, the Company or any such Subsidiary in attempting to obtain such consent, approval or authorization as 15 promptly thereafter as practicable. If such consent, approval or authorization cannot be obtained, each Seller shall use all of its commercially reasonable efforts to provide the Purchaser, the Company or such Subsidiary, as the case may be, with the rights and benefits of the affected lease, license, contract, commitment or other agreement or arrangement for the term of such lease, license, contract or other agreement or arrangement, and, if such Seller provides such rights and benefits, the Company or such Subsidiary, as the case may be, shall assume the obligations and burdens thereunder.

Prior to the Closing, each Seller shall promptly notify the Purchaser in writing of (a) all events, circumstances, facts and occurrences arising subsequent to the date of this Agreement which could result in any breach of a representation or warranty or covenant of such Seller in this Agreement or which could have the effect of making any representation or warranty of such Seller in this Agreement untrue or incorrect in any respect, (b) all other material developments affecting the assets, Liabilities, business, financial condition, operations, results of operations, customer or supplier relations, employee relations, projections or prospects of the Company or any Subsidiary and (c) any Material Adverse Effect.

Each Seller immediately shall cease and cause to be terminated all existing discussions, conversations, negotiations and other communications with any Persons conducted heretofore with respect to any of the foregoing. Such Seller shall notify the Purchaser promptly if any such proposal or offer, or any inquiry or other contact with any Person with respect thereto, is made and shall, in any such notice to the Purchaser, indicate in reasonable detail the identity of the Person making such proposal, offer, inquiry or contact and the terms and conditions of such proposal, offer, inquiry or other contact. Each Seller agrees not to, and to cause the Company and each Subsidiary not to, without the prior written consent of the Purchaser, release any Person from, or waive any provision of, any confidentiality or standstill agreement to which such Seller, the Company or any Subsidiary is a party.

Further Assurances. (a) Each Seller covenants and agrees to cooperate with the Purchaser and shall use its commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things, including the making of any SEC disclosures, necessary or desirable under applicable Law and regulation, as the Purchaser may reasonably request such Seller to take or do in connection with the initial public offering of MIAT or any of its Subsidiaries.

The Purchaser agrees to honor the Company's obligations under paragraph 3 of the letter agreement dated April 2, 2004, and in addition shall extend such offer to the other minority investors of PCAA Parent LLC and Parking Company of America Airports Holdings, LLC, upon similar terms as set forth in this Agreement, including customary representations, warranties, covenants and other provisions reasonably acceptable to the Purchaser. SECTION 5.12. Non-Competition. In order that the Purchaser and the Company may enjoy the full benefit of the airport operations, MGIF agrees that for a period of two (2) years starting on the Closing Date (the "Term"), MGIF and its subsidiaries or Affiliates (individually, collectively, or in any combination, as principal, partner, member, investor, director, officer, agent, employee, consultant or otherwise) will not, without the express written approval of the Purchaser, directly or indirectly, engage in or otherwise have a material direct or indirect interest in any Competing Business. For purposes of this Section 5.12, a business shall be deemed to be a "Competing Business" if it is materially engaged in providing off-airport commercial airport parking and transportation related services at any commercial airport within North America. The parties acknowledge that (i) the restrictions contained in this Section 5.12 are reasonable and necessary in order to protect the Company's and its Subsidiaries' legitimate interests, and (ii) any violation of the restrictions contained in this Section 5.12 would result in irreparable injury to the Purchaser, the Company and its Subsidiaries. SECTION 5.13. Non-Solicitation. During the Term, MGIF agrees not to solicit for, or divert or attempt to divert, directly or indirectly, any business of the Company or any customers or suppliers of the Company. MGIF agrees that during the Term, it shall not solicit or induce any person who at any time within the previous one year period shall have been an 17 employee or independent contractor of the Company to become employed by or associated with any other person, firm or corporation, and MGIF shall not approach any such employee or independent contractor for such purpose or authorize or knowingly approve the taking of such actions by any other person, firm or corporation or assist any such person, firm or corporation in taking such action. Additionally, MGIF will not, directly or indirectly, induce or attempt to influence any employee, customer, independent contractor or supplier of the Company to terminate his or her employment or any other relations with the Company. ARTICLE VI TAX MATTERS SECTION 6.01. Preparation and Filing of Tax Returns; Payment of Taxes. (a) The Sellers shall prepare and file (in each case, at its own cost and expense and in a manner consistent with past practice) on a timely basis all Tax Returns (including returns for estimated Taxes) for the Company for all Pre-Closing Periods. The Sellers shall timely pay all taxes shown to be due and payable on such Tax returns. (b) Any refund of taxes of the Company which are allocable pursuant to this Agreement to (i) a Post-Closing Straddle Period shall be for the account of the Purchaser and (ii) a Pre-Closing Straddle Period shall be for the account of such Seller. Such Seller shall promptly pay to the Purchaser, and the Purchaser shall promptly pay (or cause to be paid) to such Seller, the amount of any such refund received by such Seller or the Purchaser, as the case may be, to the extent such other party is entitled to such refund pursuant to this Agreement. SECTION 6.02. Transfer and Similar Taxes. Notwithstanding any other provision of this Agreement to the contrary, each Seller shall be solely responsible for paying all property, sales, use, privilege, transfer, documentary, gains, stamp, duties, recording and similar Taxes and fees (including any penalties, interest or additions) imposed upon any party in connection with the transactions contemplated by this Agreement (collectively, the "Transfer Taxes"). Each Seller shall procure any stock transfer stamp required by, and accurately file all necessary Tax Returns and other documentation with respect to, any Transfer Tax. SECTION 6.03. Tax Indemnification. (a) Each Seller shall, jointly and severally, indemnify, defend, and hold harmless the Purchaser Indemnified Parties (including the Company) from and against any and all Excluded Taxes and against any loss, damage, liability or expense (including reasonable fees for attorneys and other outside consultants) incurred in contesting or otherwise in connection with any such Excluded Taxes. (b) All amounts payable or to be paid under this Section 6.03 (the "Tax Indemnity Payments") shall be paid in immediately available funds within five (5) Business Days after the later of (i) receipt of a written request from the party entitled to such Tax Indemnity Payment and (ii) the day of payment of the amount that is the subject of the Tax Indemnity Payment by the party entitled to receive such Tax Indemnity Payment. SECTION 6.04. Contests. (a) After the Closing, the Purchaser shall promptly notify each Seller in writing of any written notice of a proposed assessment or claim in an audit 18 or administrative or judicial proceeding of the Company, which, if determined adversely to the taxpayer, would be grounds for indemnification under Section 6.03; provided, however, that the failure to give such notice will not affect the Purchaser's right to indemnification under this Agreement except to the extent, if any, that, but for such failure, such Seller would have avoided the Tax Liability in question. (b) In the case of an audit or administrative or judicial proceeding (a "Contest") that relates to a Pre-Closing Period, each Seller shall have the right, at its expense, to participate in and control the conduct of such Contest, but only to the extent that such Contest relates solely to a potential adjustment for which such Seller has acknowledged, in writing, its liability under this Agreement to hold the Purchaser and the Company harmless against the full amount of any adjustment which may be made as a result of such Contest. The Purchaser also may participate in any such Contest, and, if such Seller does not assume the defense of any such Contest, the Purchaser may defend the same in such manner as it may deem appropriate, including settling such Contest after five days' prior written notice to such Seller setting forth the terms and conditions of settlement. Notwithstanding anything to the contrary contained in this Agreement, in the event that issues relating to a potential adjustment for which such Seller has acknowledged its liability in writing are required to be contested in the same Contest as separate issues relating to a potential adjustment for which the Purchaser would be liable, the Purchaser shall have the right, at its expense, to control the Contest with respect to the latter issues. (c) In the case of a Contest that relates to a Straddle Period, or otherwise with respect to issues relating to a potential adjustment for which both the Sellers (as evidenced by its written acknowledgement of liability under this Section 6.04), on the one hand, and the Purchaser, on the other hand, could be liable, (i) each of the Sellers and the Purchaser may participate in the Contest, and (ii) such Contest shall be controlled by that party which would bear the burden of the greater portion of the sum of the adjustment and any corresponding adjustments that may reasonably be anticipated for future taxable periods. The principle set forth in this Section 6.04(c) also shall govern for purposes of deciding any issue that must be decided jointly (including choice of judicial forum) in situations in which separate issues are otherwise controlled under this Article VI by the Purchaser and the Sellers. (d) Notwithstanding anything to the contrary herein, the Sellers shall not enter into any compromise or agree to settle any claim pursuant to a Contest, which would adversely affect the Purchaser or the Company in a taxable period ending after the Closing Date without the prior written consent of the Purchaser. SECTION 6.05. Miscellaneous. (a) From and after the date of this Agreement, each Seller shall not, without the prior written consent of the Purchaser, make, or cause or permit to be made, any Tax election that would adversely affect the Company in a taxable period ending after the Closing Date. (b) Each Seller and its Affiliates shall provide the Purchaser with such cooperation and information as the Purchaser reasonably may request in connection with any Tax matters relating to the Company, including, without limitation, the filing of any Tax Return or claim for refund, the determination of any liability for Taxes or right to a refund of Taxes or the conduct of any Contest in respect of Taxes. Such cooperation and information shall include, 19 without limitation, providing the Purchaser with copies of any relevant Tax Returns, together with documents relating to rulings or other determinations by Taxing authorities. (c) Notwithstanding any provisions in this Agreement to the contrary, (i) the obligations of each Seller to indemnify and hold harmless the Purchaser Indemnified Parties pursuant to this Article VI and (ii) the representations and warranties contained in Section 3.09 shall terminate at the close of business on the 90th day following the expiration of the applicable statute of limitations with respect to the Tax Liabilities in question (giving effect to any waiver, mitigation or extension thereof). ARTICLE VII INDEMNIFICATION SECTION 7.01. Survival of Representations and Warranties. (a) The representations and warranties of each Seller contained in this Agreement shall survive the Closing until the earlier of the 18 month anniversary of the Closing or the expiration of the statute of limitation; provided, however, that (i) the representations and warranties made pursuant to Sections 3.01, 3.02, 3.03 and 3.04 shall survive indefinitely, (ii) the representations and warranties made pursuant to Section 3.09 shall survive as provided in Section 6.05(c) and (iii) insofar as any claim is made by the Purchaser for the breach of any representation or warranty of any Seller contained herein, which claim arises out of allegations of personal injury or property damage suffered by any third party on or prior to the Closing or attributable to products or inventory sold or shipped, or activities or omissions that occur, on or prior to the Closing, such representations and warranties shall, for purposes of such claim by the Purchaser, survive until thirty calendar days after the expiration of the applicable statute of limitations governing such claims. If written notice of a claim has been given prior to the expiration of the applicable representations and warranties by the Purchaser to such Seller, then the relevant representations and warranties shall survive as to such claim, until such claim has been finally resolved. (b) The representations and warranties of the Purchaser contained in this Agreement shall survive the Closing until the 18 month anniversary of the Closing; provided, however, that the representations and warranties made pursuant to Section 4.01 shall survive indefinitely. If written notice of a claim has been given prior to the expiration of the applicable representations and warranties by any Seller to the Purchaser, then the relevant representations and warranties shall survive as to such claim, until such claim has been finally resolved. SECTION 7.02. Indemnification by the Sellers. Subject to the limitations set forth in Section 7.04 hereof, the Purchaser and its Affiliates, officers, directors, employees, agents, successors and assigns (each a "Purchaser Indemnified Party") shall be, jointly and severally, indemnified and held harmless by each Seller for and against any and all Liabilities, losses, damages, claims, costs and expenses, interest, awards, judgments and penalties (including reasonable attorneys' and consultants' fees and expenses) actually suffered or incurred by them (including any Action brought or otherwise initiated by any of them) (hereinafter a "Loss"), arising out of or resulting from: 20 (a) the breach of any representation or warranty made by the Sellers contained in this Agreement; or (b) the breach of any covenant or agreement by the Sellers contained in this Agreement. To the extent that the Sellers' undertakings set forth in this Section 7.02 may be unenforceable, each Seller shall contribute the maximum amount that it is permitted to contribute under applicable Law to the payment and satisfaction of all Losses incurred by the Purchaser Indemnified Parties. SECTION 7.03. Indemnification by the Purchaser. Subject to the limitations set forth in Section 7.04 hereof, the Sellers and its Affiliates, officers, directors, employees, agents, successors and assigns (each a "Seller Indemnified Party") shall be indemnified and held harmless by the Purchaser for and against any and all Losses, arising out of or resulting from: (a) the breach of any representation or warranty made by the Purchaser contained in this Agreement; or (b) the breach of any covenant or agreement by the Purchaser contained in this Agreement. To the extent that the Purchaser's undertakings set forth in this Section 7.03 may be unenforceable, the Purchaser shall contribute the maximum amount that it is permitted to contribute under applicable Law to the payment and satisfaction of all Losses incurred by the Seller Indemnified Parties. SECTION 7.04. Limits on Indemnification. Notwithstanding anything to the contrary contained in this Agreement: (a) an Indemnifying Party shall not be liable for any claim for indemnification pursuant to Section 7.02, 7.03 or Article VI, unless and until the aggregate amount of indemnifiable Losses which may be recovered from the Indemnifying Party equals or exceeds $150,000 (the "Basket Amount"), after which the Indemnifying Party shall be liable for all Losses, including the Basket Amount and (b) the maximum amount of indemnifiable Losses which may be recovered from an Indemnified Party arising out of or resulting from the causes set forth in Section 7.02, 7.03 or Article VI, as the case may be, shall be an amount equal to $2,400,000, net of insurance proceeds. SECTION 7.05. Tax Treatment. All amounts paid under the indemnification provisions of this Agreement shall be treated as adjustments to purchase price for all Tax purposes. SECTION 7.06. Third Party Claims. (a) If any third party shall notify either the Sellers or the Purchaser ("Indemnified Party") with respect to any matter (a "Third Party Claim") which may give rise to a claim for indemnification against the other under this Article VII, then the Indemnified Party shall promptly notify the Indemnifying Party thereof in writing within 30 days of the receipt of such notice. Such notice will contain in reasonable detail, the nature and the basis of the claim and the amount thereof, to the extent known, and any other relevant information in the possession of the Indemnified Party. No delay on the part of the Indemnified 21 Party in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless the Indemnifying Party is prejudiced thereby. (b) The Indemnifying Party shall have the right at any time to assume and thereafter conduct the defense of the Third Party Claim with counsel of its choice, reasonably satisfactory to the Indemnified Party; provided, however, that the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (not to be unreasonably withheld) unless the judgment or proposed settlement involves only the payment of money damages and does not impose any equitable relief upon the Indemnified Party. (c) Unless and until an Indemnifying Party assumes the defense of the Third Party Claim as provided in Section 7.06(b) above, however, the Indemnified Party may defend against the Third Party Claim in any manner it reasonably may deem appropriate. (d) In no event will the Indemnified Party consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (which consent will not be unreasonably withheld). (e) The Indemnifying Party or the Indemnified Party, as the case may be, who is controlling the defense of the Third Party Claim shall keep the other fully informed of such claim at all stages thereof. The parties hereto agree to render to each other such assistance as they may reasonably require of each other in order to ensure the proper and adequate defense of any Third Party Claim.

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party to be bound thereby. Any waiver of any term or condition shall not be construed as a 27 waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Agreement. The failure of either party hereto to assert any of its rights hereunder shall not constitute a waiver of any of such rights. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available. SECTION 10.09. No Third Party Beneficiaries. Except for the provisions of Article VII relating to indemnified parties, this Agreement shall be binding upon and inure solely to the benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person, including any union or any employee or former employee of any Seller, any legal or equitable right, benefit or remedy of any nature whatsoever, including any rights of employment for any specified period, under or by reason of this Agreement.
