The following new Section is added to Article 8 of the Agreement: 8.4 Ownership Limitation on Purchaser. Both parties recognize that if the principal partner of the Purchaser, CEI, which is a real estate investment trust under sections 856 to 859 of the Internal Revenue Code of 1986, as amended (the "Code") (a "REIT"), were considered to own, directly or by operation of certain attribution rules, a specified interest in OpCo and/or entities owned by OpCo which are the Tenant under the Facilities Lease, the rents to be re ceived by the Purchaser would not constitute "rents from real property" under section 856(d) of the Code for purposes of determining CEI's compliance - 11 - with certain requirements of being a REIT. Both parties agree that, notwith standing anything to the contrary in this Agreement or any of the other Trans action Documents, neither the Purchaser, nor any other entity the assets of which would be attributed to CEI for federal income tax purposes in any period during which such entity owned such assets, has the right, option, or obligation, directly or indirectly, (i) to enter into the OpCo Contribution Agreement or (ii) otherwise to own any entities constituting such Tenant, and any attempt to do so will be null and void ab initio. Both parties agree that the failure of the Purchaser to cause the formation and distribution of an entity substantially conforming to the description in Schedule 8.1(p) of the Agreement shall not be considered (i) a breach entitling Seller to enforce specific performance under Section 12.2(i) of the Agreement or (ii) a breach or a failure to use commercially reasonable best efforts entitling Seller to recover damages under the last sentence of Section 8.3 or under Section 12.2(ii) of the Agreement, but only if such failure by the Purchaser occurs in reliance upon an opinion of Shaw, Pittman, Potts & Trowbridge to the Pur chaser that, if the Purchaser were to form and distribute an entity substantially conforming to the description in Schedule 8.1(p) of the Agreement, the rents to be received by the Purchaser would likely not constitute "rents from real property" or if such formation and distribution would likely expose the Pur chaser to a tax exceeding $10 million under section 857(b)(5) of the Internal Revenue Code of 1986, as amended. 11. Continuation of Agreement. The Agreement shall continue in full force and effect as modified hereby. In the event of any conflicts or inconsistencies between this Amendment (including all exhibits and Schedules attached hereto) and the Agreement, the provisions of this Amendment shall control. 12. Counterparts. This Amendment may be signed in any number of counter parts, each of which shall be an original, with the same effect as if the signa tories thereto and hereto were upon the same instrument. Signatures may be transmitted by facsimile and will be accepted and considered effective as long as such signatures are followed up with signature pages with original signa tures within two (2) business days thereafter. - 12 - IN WITNESS WHEREOF, this Amendment has been duly executed and delivered by the parties hereto effective as of the date first above written.
