The term of this Agreement (the "Site Acquisition Term") shall commence on the date of this Agreement and shall expire on December 31, 2001. (a) This Agreement may be terminated as to any particular Search Ring upon written notice by either party following the other party's breach of an obligation or covenant on such party's part to be performed with respect to that Search Ring, which breach is not cured within thirty (30) days after the breaching party's receipt of written notice; provided, however, that so long as the defaulting party commenced appropriate curative action within such thirty (30) day period, and thereafter diligently prosecutes such cure to completion as promptly as possible, the cure period will be extended until the cure is completed. If a party fails to cure a breach within this thirty (30) day period, as it may be extended, the party will be in default under this Agreement as it applies to the applicable Search Ring; and (b) Neither a termination nor the expiration of this Agreement shall affect: (i) the term of the MSA or any SLA, as that term is defined herein, which has been entered into by the parties prior to the date of termination of this Agreement, which shall continue in accordance with its terms and conditions; (ii) the terms of this Agreement that apply to any SLA which has been entered into by the parties prior to the date of termination of this Agreement; 4 [***] - CONFIDENTIAL TREATMENT REQUESTED (iii) any duties or obligations for payment or performance that are or become owing hereunder prior to the effective date of such termination; (iv) the terms of this Agreement that apply to any Search Ring which was issued prior to the date of termination of this Agreement; or (v) any other duties or obligations that expressly survive the termination or expiration hereof. (c) A default regarding one Search Ring shall not constitute a default under this Agreement; however, a default under the greater of: (1) [***] Search Rings; or (2) [***] or more of the Search Rings which have been issued pursuant to this Agreement, shall constitute a default under every Search Ring and a default under this Agreement. In the event of such a default, Horizon shall be entitled to terminate the services of BTS Company and complete or engage a third party to complete BTS Company's responsibilities under this Agreement pursuant to the Plans and Specifications (as hereinafter defined) provided by BTS Company. In such event, Horizon shall convey the Tower Facilities (as hereinafter defined) and any site development materials including ground leases and title, environmental and geotechnical reports to BTS Company upon completion, lien free, and BTS Company shall reimburse Horizon for the reasonable costs of completing its responsibilities and pay Horizon the applicable site development fee set forth in the Site Development Agreement (as hereinafter defined). 2.5 GROUND LEASES. The acquisition of BTS Sites by BTS Company pursuant to this Agreement shall be accomplished using a lease agreement in substantially the same form as the Option and Lease Agreement which is attached hereto as Exhibit "B" (hereafter the "Ground Lease"). In no event shall BTS Company agree to material modifications to the provisions set forth in paragraph 35 of the Ground Lease without Horizon's prior written approval. The acquisition of Collocation Sites by BTS Company pursuant to this Agreement shall be accomplished using a lease agreement which Horizon shall provide to BTS Company or on such other form which Horizon may, in its sole discretion, approve. 2.6. ACCEPTANCE AND REJECTION OF COLLOCATION SITES. Horizon may at any time in its sole and absolute discretion accept or reject any proposed Collocation Site. Without limiting the foregoing, Horizon may withdraw its prior acceptance of a Collocation Site and thereby reject such Collocation Site. A withdrawal or a rejection by Horizon of a Collocation Site shall not affect its obligation for fees earned through the date of termination for Site Acquisition Services as more particularly described in Section 2.2. 2.7 ACCEPTANCE AND REJECTION OF BTS SITES; EXECUTION AND DELIVERY OF SLAS. (a) A BTS Site shall be deemed to be an accepted BTS Site from and after the date that the Candidate Site which corresponds to the BTS Site has been approved by Horizon pursuant to Section 2(a) of Schedule A and shall continue to be deemed an accepted BTS Site unless and until Horizon rejects the BTS Site pursuant to section 2.7(b) hereof. 5 (b) Horizon may at any time prior to the parties' execution and delivery of an SLA corresponding thereto, and in Horizon's sole and absolute discretion, reject any BTS Site. In the case of a BIS Site that is accepted by Horizon, the following shall apply: (i) BTS Company shall continue the diligent, thorough and professional prosecution of Site Acquisition Services (including the completion of Ground Lease negotiations and required zoning, land use and permitting matters) necessary for the construction of a communications tower and related facilities consistent with the criteria theretofore identified by Horizon; (ii) Subject to Section 2.7(b)(iii) below, BTS Company and Horizon shall prepare and finalize the SLA (and exhibits thereto) applicable to such BTS Site; (iii) Within thirty (30) days following BTS Company's receipt of all necessary zoning or other land use permits or approvals applicable to the improvements to be constructed by BTS Company on the BTS Site and the completion of Site Acquisition Services in accordance with the Objectives and Procedures, but subject to Section 2.7(b)(iv) below, Horizon and BTS Company shall execute and deliver the SLA applicable thereto. Unless Horizon rejects the applicable BTS Site within thirty (30) days following notice by BTS Company of BTS Company's receipt of all necessary zoning or other land use permits or approvals applicable to the landlord improvements to be constructed by BTS Company on the BTS Site and BTS Company's completion of Site Acquisition Services in accordance with the Objectives and Procedures, BTS Company shall be unconditionally obligated to enter into the SLA with respect thereto upon receipt of the foregoing permits and approvals, and shall thereafter perform its obligations thereunder in accordance with the SLA and this Agreement. Notwithstanding any provision of this Agreement to the contrary, in the event that Horizon neither accepts nor rejects the BTS Site within thirty days as provided herein, BTS Company may, at BTS Company's sole option either (1) deem the BTS Site approved (in which event BTS Company shall be entitled to compel Horizon to execute a SLA with respect to the BTS Site) or (2) deem the BTS Site to be denied and make demand on Horizon for payment of the fees earned for Site Acquisition Services. (iv) Horizon may in its sole and absolute discretion withdraw its prior acceptance of a BTS Site, and thereby reject said BTS Site, at any time prior to the BTS Company parties' execution and delivery of the SLA for such BTS Site. (c) In the event of a rejection by Horizon of a BTS Site, including a rejection after a prior acceptance thereof as described above in Section 2.7(b) hereof, Horizon's only obligation for such BTS Site shall be for the payment of Site Acquisition Services incurred prior to such rejection with respect to the Search Ring containing such BTS Site in accordance with Section 2.2. In such event, Horizon agrees not to develop the rejected BTS Site as a tower site and further agrees not to transfer the associated Work Product to any third party, including Affiliates. 6 (d) In the event of a rejection by Horizon of a BTS Site, BTS Company may elect to forego the compensation set forth in Section 2.2 and retain the Work Product. In such event, Horizon shall have the right, but not the obligation, for a period of one (1) year following the construction of a tower on such Site to enter into an SLA for such Site pursuant to the MSA as if such Site were constructed as an accepted BTS Site; provided, however, that Horizon shall not be entitled to compensation for such Site under the Site Development Agreement. (e) This Section 2.7 shall not be deemed to limit or restrict any rights of termination of a SLA as expressly set forth therein. Horizon's rights of rejection with respect to a BTS Site contained in this Section 2.7 shall be in addition to, and not in lieu of, any SLA termination rights. (f) In the event that BTS Company's due diligence investigation of a BTS Site reveals any defect in such Site which BTS Company reasonably believes would materially adversely affect BTS Company's multi-tenant use or ownership of such Site, BTS Company shall be entitled to reject such Site upon notice to Horizon. In such event, Horizon shall have the right to designate another candidate site as the preferred candidate. BTS Company shall bear all costs associated with Site Acquisition Activities and all costs associated with the due diligence investigation, zoning, and permitting of such Site. 2.8 CONTINUED PERFORMANCE OF SITE ACQUISITION SERVICES FOLLOWING SITE ACCEPTANCE OR REJECTION. Unless otherwise notified by Horizon, BTS Company shall: (a) Following Horizon's acceptance of any Site, continue to perform Site Acquisition Services with respect to such accepted Site in accordance with this Agreement including, without limitation, the Objectives and Procedures; and (b) Following Horizon's rejection of any Site (including a rejection after Horizon's prior acceptance thereof), continue to perform Site Acquisition Services with respect to the Search Ring pertaining thereto (including a modified Search Ring as described above in Section 2.3 hereof) in accordance with the terms and conditions of this Agreement, including, without limitation, the Objectives and Procedures. 2.9 NO CONFLICTING OBLIGATIONS.

BTS Company shall provide to Horizon during the Site Acquisition Term BTS Company's primary duty of loyalty and professionalism in the 7 performance within the geographic area of Site Acquisition Services hereunder. BTS Company shall not perform, or undertake to perform, any services that would conflict with BTS Company's loyal, professional and diligent performance of its duties hereunder. The foregoing provisions of this Section 2.9(a) shall not apply if BTS Company notifies Horizon of a pre-existing conflict upon BTS Company's receipt of a Search Ring, nor will it apply to a Search Ring after BTS Company has completed construction of a BTS Site within such Search Ring. (b) In the course of performing Site Acquisition Services or otherwise in conducting its activities under or with respect to this Agreement or any SLA, BTS Company shall not publish or distribute any materials or documentation using Horizon's name without Horizon's express prior written permission specifically relating to such use; provided, however, that BTS Company shall be entitled to utilize Horizon's name where reasonably necessary to facilitate zoning and other governmental approvals. 2.10 COMPLIANCE WITH LAWS.
