Pathnet shall have no responsibility for (i) any taxes (including but not limited to transfer, sales, use, income or property taxes), assessments or other impositions attributable to Conduit (Innerduct) or other telecommunications assets or services provided to Railroad pursuant to Article 8 of the License Agreement; (ii) taxes based on Railroad's income or corporate franchise; or (iii) property or franchise taxes that are attributable to the Rail Corridor and not to Pathnet's Facilities or System. Railroad shall reimburse Pathnet for any such taxes, assessments or impositions within thirty (30) days after written request. 14.5 Mutual Cooperation. Each party shall cooperate with the other party, at the first party's sole cost and expense, in the prosecution of any claim for refund, rebate, reduction or abatement of any taxes which are the responsibility of the first party under the Agreements or the Contribution Agreement, provided that a reasonable basis exists for such refund, rebate, reduction or abatement. The first party shall reimburse the second party for all reasonable out of pocket expenses incurred in connection therewith. Notwithstanding any other provision of this Section, the first party is not obligated to pay or reimburse the second party for any tax for which the first party is liable under this Section if the party first elects to prosecute a claim for reduction or abatement of such taxes and prepayment thereof is not a condition to prosecuting the claim. The first party shall pay or reimburse the second party for any such taxes when the taxes finally are adjudged to be due and owing by the highest administrative or judicial authority to which an appeal has been taken. 15. SITES FOR NON-CABLE FACILITIES. 15.1 Non-Cable Areas. Railroad, insofar as it has the right and can reasonably do so, shall make available to Pathnet for Pathnet's sole use, areas not to exceed five hundred (500) square feet within the Designated Rail Corridor for use by Pathnet as Repeater (Regen) Sites, or power or auxiliary power stations, or sites for construction facilities or temporary storage of materials and fuel for power stations. Railroad shall have no duty to provide such sites at a requested location if the width, nature or other uses or planned uses of the Rail Corridor by Railroad at such location or if restrictions on Railroad's title or interest in the property preclude such use by Pathnet. 15.2 Adjacent Land. If for any reason, Railroad is unable to provide such site within the Designated Rail Corridor, and Railroad has available adjacent land suitable for the location of such site, then Railroad shall furnish the use of a reasonable portion of such adjacent land to Pathnet for such site at a fee to be negotiated; provided, however, that such use will not interfere with Railroad's current or reasonably foreseeable future use of such property. Such adjacent land usage shall be documented by Railroad's standard form lease, the form of which is attached hereto as Exhibit C. 12 15.3 No Obligation as to Third Parties. Notwithstanding the provisions of Sections 15.1 and 15.2, Railroad shall have no obligation to provide or make available any portion of any adjacent land or allow the expansion of any structure of Pathnet located thereon beyond five hundred (500) square feet or such additional size initially improved by Pathnet with the approval of Railroad, which approval may be withheld in its sole discretion, for use by third party purchasers, sublicensees, transferees or permitted assignees. Any such accommodation shall be at a fee to be negotiated, shall not interfere with Railroad's current or future use of such property and shall be documented by Railroad's standard form lease, the form of which is attached hereto as Exhibit C. This Section 15.3 shall not apply to Pathnet's partners in development of the Rail Corridor, and shall not restrict Pathnet's ability to make space in Pathnet's existing Facilities available to third parties on such terms as Pathnet determines in its sole discretion. Pathnet shall, except to the extent caused by Railroad's gross negligence or willful misconduct, (i) assume responsibility for any and all claims, liabilities, damages, costs (including reasonable attorneys' fees) and expenses arising out of or based upon the acts or omissions of any such third party in or around such non-cable facilities, the Rail Corridor or other Railroad property, and (ii) indemnify, defend and hold Railroad harmless from and against any and all losses and damages suffered by such third party as a result of the presence of such third party or its facilities or equipment in or around such non-cable facilities, the Rail Corridor or other Railroad property. 15.4 Rent. Rents for any land(s) outside of the Designated Rail Corridor, or for lands within the Designated Rail Corridor in excess of five hundred (500) square feet or for uses other than those described in Section 15.1, shall be at a fee to be negotiated. 15.5 Approval of Structure. The location and size of any buildings or other structures to be placed by Pathnet or any third party within Railroad's Rail Corridor or on Railroad's other property shall be as approved by Railroad's Engineer, which approval may be withheld in his or her sole discretion, on plans submitted in accordance herewith. 16. INDEPENDENT CONTRACTOR STATUS. 16.1 Except with respect to the Contracted Railroad Personnel, Railroad reserves no control whatsoever over the employment, discharge, compensation of or services rendered by Pathnet's employees, agents or contractors, and it is the intention of the parties that Pathnet shall be and remain a licensee and that nothing herein shall be construed as inconsistent with that status or as creating or implying any partnership or joint venture relationship between Pathnet and Railroad. 17. LIABILITY; INDEMNITY. 17.1 Pathnet's Release and Indemnification. Recognizing that Railroad has owned and/or operated the Rail Corridor for many years prior to the Effective Date and prior to entry thereupon by employees, agents, contractors or representatives of Pathnet, and in addition to the indemnities otherwise provided in the Agreements, Pathnet hereby assumes, releases and shall defend, indemnify, protect and save Railroad harmless from and against the following: (a) All claims, liabilities, losses, damages, causes of action, costs, and expenses (including reasonable attorneys' fees and costs) arising from: (1) damage to or destruction of Pathnet's Facilities or System except to the extent attributable to the willful misconduct of 13 Railroad, its employees or contractors and (2) loss of service or use of Pathnet's Facilities or System or loss of revenue or profit therefrom, including any claim or loss to any client, customer, patron or other purchaser, transferee, sublicensee or permitted assignee of Pathnet's rights or services resulting from any damage to or destruction of Pathnet's Facilities or System. Railroad shall not under any circumstances be liable for interruption of or damage to the installation, operation, maintenance or repair of Pathnet's Facilities or System unless attributable to the willful misconduct of Railroad, its employees (including Contracted Railroad Personnel), agents, contractors, or other parties performing services for Railroad. In no event shall Railroad be liable for loss of income, cost of substitute service, or other consequential damages of any kind; (b) All claims, liabilities, losses, damages, causes of action, costs, and expenses (including reasonable attorneys' fees and costs) arising from injury to or death of any persons on or about Pathnet's Facilities or System, including, but not limited to, Pathnet's employees, agents, contractors, subcontractors, invitees, or other such third parties, purchasers, transferees, permitted assignees, licensees or sublicensees, resulting from the existence, construction, maintenance, operation, use, repair, change, placement, replacement, relocation and/or subsequent removal of Pathnet's Facilities or System, or any part thereof, or the use of the Rail Corridor or other Railroad Property, regardless of any approvals, reviews, controls or standards imposed by Railroad or other actions of Railroad, unless such claims, losses, damages, causes of action, costs, and expenses (including reasonable attorneys' fees and costs) result from the willful misconduct of Railroad; (c) All claims, liabilities, losses, damages, causes of action, costs and expenses (including reasonable attorneys' fees and costs) arising from any breach of the Agreements by Pathnet, including, but not limited to, any failure of Pathnet to support track and/or roadbed, as provided herein or any failure of Pathnet to secure permits or other approvals as provided herein, regardless of cause, including Railroad's negligence, but excluding Railroad's willful misconduct; (d) All claims, liabilities, losses, damages, causes of action, costs, and expenses (including reasonable attorneys' fees and costs) arising from any slide, soil disturbance or environmental damage or impairment resulting from the existence, construction, installation, maintenance, operation, use, repair, change, placement, relocation and/or subsequent removal of Pathnet's Facilities or System, regardless of cause, including Railroad's negligence, but excluding Railroad's willful misconduct; (e) Any claim (regardless of merit), loss or damages awarded, whether civil or criminal, under any antitrust laws, or under any federal, state or local regulatory actions, attributable to issues arising under the Agreements, it being understood and agreed that this indemnity shall not apply to any claims, loss or damage arising out of any other agreement between the parties or the parties' performance thereunder, including the contributions set forth in the Contribution Agreement; in any such actions, Railroad shall have the right to designate and/or employ independent counsel, if deemed necessary by Railroad, to protect its interests, and the expense of such representation shall be paid or reimbursed by Pathnet; (f) Reserved. (g) All claims, liabilities, losses, damages, causes of action, costs, and expenses (including reasonable attorneys' fees and costs) arising from any damage or injury to (including 14 loss of use or service of or loss of revenue or profit from) any facilities, cables, wires, pipes, casings, conduits, innerducts or ducts of any other party or Conduit Right-of-Way operator or user, licensee, sublicensee, transferee, purchaser or permitted assignee arising out of or related to any act or omission of Pathnet or Pathnet's employees, agents, contractors, subcontractors, licensees, sublicensees, customers, partners, the Contracted Railroad Personnel or others acting at the direction of any of the foregoing, unless caused by the willful misconduct of Railroad or Contracted Railroad Personnel; (h) All claims, liabilities, losses, damages, causes of action, costs, and expenses (including reasonable attorneys' fees and costs) arising from any act or omission of Pathnet or Pathnet's employees, agents, contractors, subcontractors, licensees, sublicensees, customers, partners, the Contracted Railroad Personnel or others acting at the direction of any of the foregoing which are not expressly assumed by Railroad under Section 17.2. 17.2 Railroad's Indemnification. Railroad hereby assumes responsibility for, and shall indemnify, defend and hold Pathnet harmless from, claims, liabilities, losses, damages, causes of actions, costs, and expenses (including reasonable attorneys' fees and costs) arising from: (a) Death of or injury to any employee(s) of Railroad or Railroad's Affiliates, other than Contracted Railroad Personnel; (b) Destruction of or damages to any Railroad or Railroad Affiliate facilities or equipment (moving or stationary) or property; (c) Interruption to or cessation of freight rail service; (d) The willful misconduct of Railroad's Affiliates or, notwithstanding anything to the contrary contained herein, Contracted Railroad Personnel. UNLESS such claim, liability, loss, damage, cause of action, cost or expense is caused by, arises from, or results in whole or in part from: (i) any act or omission of Pathnet (including, but not limited to, any improper or negligent plan and/or design, construction, installation, maintenance, placement, operation, repair, relocation use or removal of Pathnet's System or Facilities); (ii) any breach of the Agreements by Pathnet; (iii) any direct rescheduling, delay or diversion costs, as set forth in Exhibit B; or (iv) any matter which is the subject of Pathnet's release and indemnification in Section 17.1. 17.3 Notice of Claims; Indemnification Procedures. Upon receipt of notice by Railroad or Pathnet, as applicable, (the "Indemnitee"), of any loss, event, happening or occurrence which would be the basis of a claim by the Indemnitee under the provisions of this Article 17 (an "Indemnified Claim"), the Indemnitee shall immediately provide written notice to the other party (the "Indemnitor") of such Indemnified Claim. So long as the Indemnitor is not in default in the 15 performance of its obligations under the Agreements, as between the Indemnitee and the Indemnitor, the Indemnitor shall retain primary responsibility for the conducting of any legal and/or administrative action or other proceeding regarding any such Indemnified Claim (an "Indemnified Claim Proceeding") and the defense (and any appropriate appeal) thereof. Legal counsel retained with respect to any Indemnified Claim proceeding shall be selected by the Indemnitor, but shall be subject to the reasonable prior approval of the Indemnitee. As between the Indemnitee and the Indemnitor, all costs incurred with respect to any Indemnified Claim Proceeding (including, but not limited to, reasonable costs and attorneys' fees) shall be borne by the Indemnitor, and the Indemnitor's indemnification obligations set forth in this Article 17 shall extend to all such costs. Nothing contained herein shall in any way limit the Indemnitee's right to participate and/or retain independent legal counsel, at the Indemnitee's expense, with respect to any Indemnified Claim proceeding, but the Indemnitee shall cooperate with the Indemnitor and coordinate Indemnitee's participation and/or use of such independent counsel in a matter not inconsistent with Indemnitor's positions and interests in such Indemnified Claim Proceeding, to the extent reasonably possible and not adverse to the interests of Indemnitee. Notwithstanding the foregoing, in the event Indemnitee determines, in Indemnitee's reasonable opinion, that there is a conflict of interest or other circumstance whereby such Indemnitor's retained legal counsel cannot adequately represent Indemnitee's interests in any Indemnified Claim Proceeding, Indemnitee shall have the right to retain independent legal counsel and Indemnitor's indemnification obligations set forth in this Article 17 shall extend to all costs incurred with respect to such separate representation. In the event that an Indemnitor defends an Indemnitee pursuant to the terms hereof, and the final adjudication determines that the Indemnitee bears some portion of liability under the Indemnified Claim which is not subject to the Indemnitor's indemnification obligations hereunder, the costs of such defense will be apportioned between the Indemnitor and Indemnitee based upon such parties' ultimate liability after giving effect to the indemnification provisions hereof. Any settlement of an Indemnified Claim shall be subject to the written approval of both the Indemnitee and the Indemnitor. Indemnification payment shall be made within thirty (30) days of such approval. 17.4 Exceptions to Liability. Notwithstanding any contrary provision contained herein, (a) Railroad shall not have any liability whatsoever for any death of or injury to persons or damage to or loss of property arising from or resulting in connection with any train derailment, and Pathnet hereby releases Railroad and its Affiliates from any and all claims, liabilities, losses, damages, causes of action, costs and expenses (including reasonable attorneys' fees and costs) arising from or resulting in connection with any train operation, accident or derailment, irrespective of the negligence, gross negligence or willful misconduct of Railroad, and (b) Pathnet shall have no liability relating to any Conduits (Innerducts) installed for or capacity sold or made available to Railroad pursuant to the License Agreement; provided, however, that (x) any such Conduits (Innerducts) shall be of equal or greater quality as Pathnet's own Conduits (Innerducts), and (y) Pathnet shall grant the same remedies to Railroad with respect to such capacity as Pathnet grants to its customers in the ordinary course of its business (e.g., outage credits, it being understood that Pathnet shall not be obligated to make any monetary payments as a remedy in connection with such capacity), which Railroad acknowledges may not provide it with any incremental benefit. 17.5 Survival. The provisions of this Article 17 shall survive the expiration or earlier termination of the Agreements. 16 18. INSURANCE. 18.1 Railroad Protective Liability Insurance. Before any period of construction of any portion of the System or Facilities (including preliminary surveys and inspections), Pathnet shall purchase, or cause its contractor(s) to purchase, and to maintain in full force and effect, Railroad Protective Liability Insurance ("RPL") naming Railroad as the insured. Said RPL policy shall be written on the form prescribed in the Federal Aid Highway Program Manual, Volume 6, Chapter 6, Section 2, Subsection 2, as amended from time to time, or as superseded by the AAR/AAHSTO form, and shall provide available limits of not less than $5,000,000 per occurrence, $10,000,000 aggregate for bodily injury and property damage (unless Pathnet designates a hazardous material Rail Corridor as a Conduit Right-of-Way, and then $10,000,000 per occurrence, $20,000,000 aggregate). The original of said RPL policy shall be furnished to and approved by Railroad, prior to the commencement of any entry or other operations under the Agreements. 18.2 Liability Insurance. Pathnet shall purchase and maintain, until all of its obligations under the Agreements have been fully discharged and performed, the following insurance coverage: (a) Commercial General Liability Insurance ("CGL"), including any applicable umbrella policy, with contractual liability covering actions assumed in the Agreements by Pathnet, providing for available limits of not less than $5,000,000 single limit, bodily injury and/or property damage combined, for damages arising out of bodily injuries to or death of all persons in any one occurrence and for damage to or destruction of property, including the loss of use thereof, in any one occurrence, including Federal Employers Liability Act claims ("FELA") against the Railroad, or other liability arising out of or incidental to railroad operations; (b) Workers' Compensation, Employer's Liability Insurance and Occupational Disease Insurance; and (c) Business Automobile Liability Insurance. If any motor vehicles are used in connection with the work to be performed under the Agreements, Pathnet shall purchase and maintain Business Automobile Liability Insurance with limits of not less than $2,000,000 single limit, bodily injury and/or property damage combined, for damages to or destruction of property including the loss of use thereof, in any one occurrence. If, in Railroad's reasonable opinion, a higher limit of liability is necessary for any insurance policy required hereunder, Railroad shall so notify Pathnet and Pathnet shall, within thirty (30) days of receipt of such notice, provide a copy of the endorsement to the appropriate policy increasing the liability coverage to the required limit. 18.3 Policy Requirements. All insurance required hereunder shall be effected by valid and enforceable policies issued by insurer(s) of financial responsibility and authorized to do business in the states where the System and/or Facilities are located, all subject to the reasonable prior approval of Railroad. Except for the RPL policy (on which Railroad shall be the named insured), Pathnet's liability insurance policies shall name Railroad as an additional insured and will not have any exclusions for liability relating to railroad operations by endorsement. The Pathnet's Workers' Compensation and property insurance policies shall include waivers of subrogation rights endorsements. All policies shall contain a provision for thirty (30) days' written notice to Railroad prior to any expiration or termination of, or any change in, the coverage provided. The insurance company shall be required to provide Railroad with at least thirty (30) days' written notice prior to such expiration, termination or change in any insurance coverage. Prior to any entry upon the Rail Corridor pursuant to the Agreements and upon Railroad's request thereafter, Pathnet shall provide Railroad with the original RPL policy and with certificates of insurance for all other coverages showing that the required coverages are in effect for the term of 17 the Agreements. The liability assumed by Pathnet under the Agreements, including, but not limited to, Pathnet's indemnification obligations, shall not be limited to the insurance coverage stipulated herein. 19.

During the Planning and Design and the Installation and Construction Phases, Pathnet shall, except in the case of emergency, give Railroad's Engineer at least ten (10) days' written notice before commencing construction or bringing any vehicle or equipment onto the Rail Corridor or other Railroad property, and forty-eight (48) hours' notice before any other entry. Any such written notice shall state the name(s) of Pathnet employee(s) in charge or contractor(s) or subcontractor(s) performing work or making such entry. 19.3 Maintenance and Operation Phase Access Notice. During the Maintenance and Operation Phase, in order to secure safety of operated trains, crews, passengers and cargo of Railroad, and safety of Pathnet employees and/or contractors, Pathnet shall give CSXT's local Director of Dispatch, (904) 381-2765 and (904) 359-7551, as representative of Engineer, advance telephone or telegraph notice of entry onto any portion of the Rail Corridor, which entry shall be subject to consent and approval of Railroad's Engineer as to method and timing, which approval may be withheld in his or her sole discretion. Any such notice shall state the name(s) of Pathnet's employee(s) or contractor(s) or subcontractor(s) performing work or making such entry. 19.4 Emergency Notice. In case of disaster (such as a train derailment or System failure) or other emergency demanding immediate examination or repairs to the existing System or Facilities, notice shall be given by either party to the other in person or by telephone to the Emergency Response Center(s) designated on Exhibit H attached hereto or as otherwise designated in writing by each party to the other. Such initial verbal or telephonic notice, however, must be confirmed in writing within forty-eight (48) hours. Each party will cooperate with the other to permit restoration of each party's operations as promptly as feasible after such emergency. 20. RELOCATIONS; ALTERATIONS. 20.1 Relocation to Accommodate Railroad. If Railroad determines that any Pathnet Facilities or System must be changed, altered or relocated after initial construction because of Railroad's own track or facility relocations or rail operational needs or plans (including additions, changes to track(s) to accommodate freight or passenger customers of Railroad), or any governmental agency or requirement, Railroad shall promptly give written notice thereof to Pathnet of such needs, plans or requirements. Within sixty (60) days of receipt of such notice, Pathnet shall protect or move the Pathnet Facilities and System, at Pathnet's sole cost and expense, and in a manner satisfactory to Railroad; provided, however, that Railroad shall reimburse Pathnet for any such costs or expenses received by Railroad from a governmental entity or other entity in connection with such relocation. 20.2 Relocation to Accommodate Third Party. In the event of a Railroad relocation to accommodate any third party other than as provided in Section 20.1, Pathnet shall protect or move its Facilities and System upon receipt from Railroad of an agreement, in writing, obligating such third party to reimburse Pathnet for all costs and expenses incurred by Pathnet, including reasonable administrative and overhead, in connection therewith, or, if Railroad is unable to obtain such an agreement from such third party, Railroad's agreement to reimburse Pathnet for the 19 foregoing costs (not to include any reimbursement of lost income). Pathnet shall submit any invoice to Railroad within ninety (90) days after such relocation work is completed. 20.3 Replacement Land. In the event of any relocation of Pathnet's System or Facilities under Section 20.1, Railroad shall not be required to purchase for Pathnet any replacement land or right-of-way or to pay Pathnet the cost to secure same if there is not available Rail Corridor. However, Railroad agrees to allow Pathnet to relocate to any other available adjacent or nearby Rail Corridor or other land owned by Railroad at Pathnet's sole cost; provided, however, that Railroad shall not be entitled to any additional payment for such replacement Railroad land or Rail Corridor and the total mileage of such Rail Corridor or replacement land to which Pathnet relocates shall be deducted from and the abandoned Rail Corridor shall be added to the total mileage of Designated Rail Corridor permitted under the License Agreement. 21. LINE SALES; ABANDONMENT. 21.1 In the event of a sale or other transfer of any portion of the Designated Rail Corridor, such sale shall be made expressly subject to the Agreements and the rights of Pathnet thereunder. Notwithstanding any provision herein to the contrary, Railroad shall have the absolute right, in its sole discretion, to effect an Abandonment of all or any portion of the Rail Corridor. 22. CONDEMNATION. 22.1 Severance of Interests. In the event that any portion of the Designated Rail Corridor becomes the subject of a condemnation or appropriation proceeding or offer to acquire, Pathnet's interest (in its Facilities and/or System and in its occupation of the Segment) shall be severed from Railroad's interest (both physical and ownership rights) in such proceedings, and the parties agree to have any such condemnation or appropriation awards specifically allocated between Pathnet's interest and Railroad's interest. 22.2 Removal of Facilities. Should any Segment of the Designated Rail Corridor used by Pathnet for a part of Pathnet's Fiber Optic Communications System or Facilities be condemned, appropriated and/or acquired by any governmental agency (or other party cloaked with the power of eminent domain) for public purpose or use, then to the extent required by the condemning authority, any Facilities or System of Pathnet within such Designated Rail Corridor not condemned, appropriated and/or acquired by such agency or authority shall be promptly removed by Pathnet at Pathnet's cost, unless Pathnet makes other arrangements with the condemning or appropriating agency or authority. 22.3 Notice. Railroad shall promptly notify Pathnet of any condemnation or appropriation action filed against any portion of the Designated Rail Corridor. Railroad shall also promptly notify Pathnet of any threatened condemnation or offer to acquire by any governmental agency (or other party cloaked with the power of eminent domain) affecting the Designated Rail Corridor (provided the Railroad employees administering this Agreement have actual knowledge thereof). Further, any voluntary sale to the condemning or appropriating agency or authority pursuant to any threatened condemnation or offer to acquire shall be in accordance with the provisions of Article 21. 20 23. PATHNET DISCONTINUANCE. 23.1 In the event of any Discontinuance by Pathnet of its Facilities, System, Segment or any substantial portion thereof, Railroad shall have the option, to be exercised in Railroad's sole discretion, to terminate this Agreement as to the affected Segment(s) upon written notice to Pathnet. Upon such termination, removal of Pathnet's Facilities and System within such affected Segment(s) shall be governed by Section 26.2 hereof. 24. RAILROAD'S RIGHT TO TERMINATE OR REQUIRE SUSPENSION OF ACTIVITIES; FAILURE TO MAKE TIMELY PAYMENT 24.1 Material Breach; Remedy. If Pathnet or Railroad fails to perform, violates or defaults under any material terms or conditions of the Agreements ("Material Breach"), and fails to remedy any such Material Breach in accordance herewith, then and in that event, the non-defaulting party shall have the following rights and remedies: (i) if the Material Breach (a) adversely affects railroad safety or operation, or (b) relates to the payment of any fees and expenses due to Railroad under the Agreements, Railroad shall have the right to terminate this Agreement upon written notice to Pathnet; and (ii) if the Material Breach is not of the type and nature described in Subsection 24.1(i), Railroad shall have the right, upon written notice to Pathnet, to suspend immediately all then pending and future installation, construction, maintenance and/or deployment on the entire Rail Corridor until such time as the applicable Material Breach is cured and Pathnet demonstrates to Railroad's reasonable satisfaction that Pathnet has taken such steps and/or implemented such procedures so that the particular Material Breach in question will not recur. Upon termination as provided in this Section 24.1, removal of Pathnet's Facilities and System shall be governed by Section 26.2 hereof. Railroad's right to terminate this Agreement shall be limited to occurrences of Material Breaches of the type and nature described in Subsection 24(i) above. 24.2 Examples of Material Breach. For purposes of this Article, any substantial noncompliance, or any repeated noncompliance, each of which might be considered minor or singular, may when considered in the aggregate constitute a Material Breach. In illustration, but without limitation, failure to give required notices, or failure to give required approvals without cause, or failure to comply with final decisions under the Dispute Resolution provisions of Article 25, may constitute a Material Breach. 24.3 Notice and Cure Period. Pathnet and Railroad agree that neither party shall proceed against the other for any alleged Material Breach before the offending party has had written notice and reasonable time to respond and cure such breach; provided, however, that neither party shall be required to give time to respond and cure if any such delay will cause irreparable harm or increased risk of liability or injury. Reasonable time to respond and cure shall for purposes of Subsections 24.1(i)(b) and 24.1(ii) be presumed to be thirty (30) days, and for purposes of Subsection 24.1(i)(a) be presumed to be forty-eight (48) hours. If such breach cannot 21 reasonably be cured within the applicable cure period, but the party proceeds promptly to cure the same and prosecutes such cure with due diligence, the time for curing such breach shall be extended for such reasonable period of time as may be necessary under the circumstances to complete the cure, but under no circumstances shall such additional period extend beyond, (i) for purposes of Subsection 24.1(ii), one hundred eighty (180) days without the specific written approval of the non-breaching party, which such approval may be withheld in such party's reasonable discretion, and (ii) for purposes of Subsection 24.1(i)(a) and (b), thirty (30) days. With respect to any Material Breach (i) which is not cured by the breaching party within the applicable cure period, or (ii) for which an opportunity to cure is not required to be given, the non-breaching party may, at its sole option, cure any such breach in the manner it deems appropriate. In such event, the breaching party, within thirty (30) days of written demand and without deduction, set-off or abatement, shall reimburse the non-breaching party for any and all expenses incurred as a result of the non-breaching party's curing of such default together with interest at the Default Rate. Nothing contained herein shall create an obligation on the part of the non-breaching party to cure any uncured breach existing at any time under the Agreements. 24.4 No Continuing Waiver. Any waiver by any party at any time of any of its rights under the Agreements shall not be deemed to be a continuing waiver of any breach or default or other matter subsequently occurring. 24.5 Waiver of Certain Damages. Except as otherwise provided in Section 6.5 of the License Agreement, neither party shall be liable to the other party for any consequential, indirect, special, exemplary or punitive damages, including, but not limited to, damages attributable to or based upon any loss of present or future profits, any loss of or injury to customer goodwill, or any lost or foregone investments and opportunities. 25. LIAISON; COORDINATION AND DISPUTES RESOLUTION. 25.1 Specified Disputes. The parties intend that any disputes which may arise between them relating to access to the Rail Corridor, or the design, plan, construction, installation, operation, maintenance, repair, replacement, and removal of Pathnet's Facilities or System or the safe and uninterrupted operation of the rail system of Railroad (a "Specified Dispute") be resolved as quickly as possible, which may, in certain instances, involve immediate decisions. When such quick resolution is not possible, or depending upon the phase of installation of Pathnet's Facilities and System, the parties agree to resolve such Specified Disputes as herein provided. 25.2 Field Representatives. Within thirty (30) days after the designation by Pathnet of the Route Plan as provided in Exhibit B, Railroad and Pathnet shall each designate in writing the division or field representative(s) as point(s) of contact for decision making concerning the Specified Disputes. 25.3 Railroad Operations. Questions of Railroad operations or track safety shall in all instances be referred to Railroad's Engineer, whose decision shall, for any emergency situation, be made within twenty-four (24) hours, or for any non-emergency situations, be made as provided in Section 25.7. 25.4 Access.

PURPOSE OF SPECIFICATIONS The purpose of these specifications is to govern the location and installation of underground communication and power cables crossing under the track(s) and/or CSXT right of way in a manner that will not interfere with present and future CSXT construction operations. B. GENERAL LOCATION OF UNDERGROUND FACILITIES 1. The cable or duct system of proposed underground crossings shall be laid as straight and direct as possible between the points where the underground line enters and leaves the property of CSXT. 2. Manholes, pull and splice boxes, and terminals in the underground crossings should be located off CSXT's right of way where possible, or at the outer edge of the right of way when on Railroad property. If the structures must be located further from the right of way line, and nearer the track(s), they must be installed below ground, and marked with identification flush with the ground. C. DESIGN CRITERIA FOR UNDERGROUND FACILITIES 1. The tops of conduits and/or ducts and cable system structures of underground cable crossings shall be located at a depth of not less than 60 inches below the bottom of the crossties. In addition, the installations shall be at least 36 inches below the bottom elevations of ditches or 42 inches below ground level for parallel installations with the lowest depth governing. Where rail-plow is authorized, conduit or cable shall be at a depth of not less than 42 inches below ground level. When installations are proposed by rail plowing, the minimum offset from the centerline of the near track shall not be less than 15 feet. When installations are proposed by tractor plowing, they shall be located more than 15 feet from the centerline of the near track. Tractor plowing will not be permitted on railroad embankments without specific site approval. The proposed conduit installations shall not be located less than 5 feet from CSXT code cables. Plowing through public or private road crossings will not be permitted. All drainage structures will be located and marked prior to plowing or trenching. Unless otherwise approved, manholes, hand hole/splice boxes shall be located at least 25 feet from the centerline of the near track where right of way is available. Unless otherwise approved, bored conduits shall clear signal control building and appurtenance foundations by 5 feet vertically. The conduits are to be clear such facilities horizontally by 5 feet if trenched and 10 feet if bored. 2. Underground crossings of power supply cables with a maximum voltage of 750 volts may be installed by pushing or boring a galvanized steel pipe under the tracks at a depth specified above to serve as a conduit, provided such pipe extends at least 25 feet beyond the outside rail on each end of the crossing and the top of pipe casing is buried at least 60 inches below the bottom of the crossties and 36 inches below ditch bottoms at all other points on the property of CSXT. Longitudinal occupancy shall be approved by the Chief Engineer to ensure that such proposed occupancy does not impair the normal functioning of Train Control equipment. Measurements to the ends of the conduits shall be to the head of the outside rail and made at right angles to the track. Additional lengths will be required for crossings in fill sections and those at angles of less than ninety degrees (90 degrees) and for multi-track crossings. Generally, on fills, two feet beyond the toes of the slopes or three feet beyond the ditch should be sufficient, (refer to Attachment No. 1 and No. 2). All ducts and/or encasement beneath the tracks must be capable of withstanding E-80 loading and conform to A.R.E.MA. Part 5, Section 5.3. Conduits and/or encasement larger than four (4) inches shall be governed by the specifications which normally cover pipelines. Jacking or boring installation is preferred, and no water is to be used in the installation of the encasement. 3. Underground crossings of communications cables of low voltage shall conform to number "2" above, except that encasement may, at the discretion of the Chief Engineer or his authorized representative, be restricted to 15 feet beyond the outside rail of spur or sidetracks measured at right angles to the track. As in number "2" above, additional lengths will be required for crossings in fill sections, etc. These criteria shall also apply to paved street sections. 4. Underground crossings of power supply cables operating above 750 volts will be installed at depths specified above. In addition, between the points where the underground crossings enter or leave CSXT 2 property, the cable is to be enclosed in galvanized steel pipe or in an approved concrete encased duct for mechanical protection of the cable. No cable of this potential, which is unprotected, will be permitted. Longitudinal occupancy shall be approved by the Chief Engineer to ensure that such proposed occupancy does not impair the normal function of Train Control equipment. If risk to inductive interference is perceived, a further examination by a third party may be required. 5. Owners of the conduits and cables shall designate the locations of such installations to aid in the prevention of damage to the cable as a result of use of Railroad's property. Signs or markers shall be placed and maintained preferably at or near the CSXT right of way line. The signs/markers shall describe the underground facility and include a telephone number of the facility owner clearly visible on each side of the track. 6. In addition to the requirements of these specifications, the underground crossing is to conform to the requirements of the National Electrical Safety Code, as published by the National Standards Institute, Inc., the latest revised edition of same being controlling. The crossing is also to conform to the requirements of any local or state laws or regulations of any local code enforcing authority that may be in effect at the time of the installation. 7. All applications for underground facilities described in this document shall be submitted to the appropriate Division Engineer or Manager, or his or her designated representative(s) having jurisdiction and must be accompanied by complete location and construction plans referenced to CSXT's milepost. No work is to be performed on CSXT property prior to granting of authority from the Division Engineer or Manager. All work on the property will be performed under the supervision of the Division Engineer or Manager. The applicants shall bear any expense incurred by CSXT or its forces, will execute the appropriate agreement and pay all fees and rentals as required by established standards or as negotiated. 8. Conduit shall be so installed as to prevent the formation of a waterway under the railroad, with an even bearing throughout its length, and shall slope to one end (except for longitudinal occupancy). 9. Bored or jacked installation shall have a bored hole with the diameter essentially the same as the outside diameter of the conduit plus the thickness of any protective coating. If voids should develop or if the hole diameter is greater than the outside diameter of the conduit (including coating) by more than one (1) inch, remedial measures, as 3 approved by the railroad's Chief Engineer, shall be taken. Boring operations shall not be stopped if such stoppage would be detrimental to the railroad. 10. Conduits and cables shall be installed by plowing methods where practical. Directional boring, and trench and back fill techniques shall be used in those locations where plowing is impractical. In all cases, the condition of the right of way will be restored, including vegetation and erosion controls to CSXT's satisfaction, and in accordance with current CSXT specifications for grading work. 11. All bridge attachment designs must be approved by CSXT. All designs are to provide for attachment to the outside of the bridge structures. Insertions or burial of casing and/or conduit where the ballast is carried across bridge decks will not be approved except for aesthetic or historic reasons. Steel pipe casing with adequate provision for contraction and expansion shall be used to support the conduit. Core drilling for installation of casing through bridge back walls, head walls, and wing walls shall be located not less than one core diameter from the top or outside face of the wall. Steel sleeves secured by approved grout material shall be installed in bores through concrete walls prior to the installation of casing. All FRA and OHSA safety rules for bridge worker safety shall apply when work is performed on bridges. Care must be taken to ensure metallic conduit shall not impair or circumvent Train Control circuitry. Excavation by blasting methods shall be employed only as a last resort, must be approved by CSXT in writing in each instance, and must comply with Sections 1..3..5..9.. of the Manual for Railway Engineering, refer to Attachment No 3. 12. Point of Presence, Regeneration and Junction Sites are to be located not less than 25 feet from the centerline of the near track. Service and access roads are to be located not less than 25 feet from the centerline of the near track. These site installations shall not interfere with existing drainage structures and systems, or service roads. Sites involving buildings or other types of sight obstructions shall be located in accordance with CSXT crossing sight distance criteria, refer to Attachment No. 4 and No. 5. 13. The owners of the proposed installations are responsible for coordination with all existing utilities located on the right of way during design and construction, and maintaining the proper clearances. The owners of the proposed installations are responsible for obtaining all construction and environmental permits, and compliance with their 4 requirements. The owners of the proposed installations are responsible for confirmation of title to right of way through CSX -- Real Property, Inc. 14. Design Plans - All plans shall be submitted to CSXT for review and approval. No work is to be initiated without approved plans on site. Plans shall be drawn to scale showing the relation of the proposed cable system to railroad tracks, railroad signals and control facilities, angles of crossings, locations of bores, manholes, hand holes, railroad survey stations, railroad mile posts with prefixes, right of way lines and general layout of tracks and facilities, etc. Also, drawings must show number of conduits, size and location of cable in the conduit, fiber count in each cable, and details of bridge attachments. A general location map together with a legend indicating line and symbol designations with on/off milepost (nearest 0.1 mile) is to be included. CSXT reserves the right to require plan modifications during construction to protect railroad facilities and operations. D. CONSTRUCTION OPERATIONS Construction operations shall be planned and organized to minimize conflicts with railroad operations. All operations are to be conducted in accordance with CSXT Safe Way policies and procedures, and are subject to CSXT approval. 1. Pre-construction conferences shall be held prior to beginning work on the right of way. Additional progress meetings and/or teleconferences may be required during the course of the work.

The owners of the facilities shall have construction managers in responsible charge on site at all times and shall provide production quantities on a daily basis to the CSXT designated representative or the consultant inspection personnel assigned to the project. 4. Accurate notes and records shall be maintained during the course of the work to enable the preparation of complete "as-built plans" upon completion of the project(s). The "as-built plans" shall accurately depict and describe the location of all facilities installed on the right of way. As-built plans shall be submitted for approval as specified in the contract with CSXT. 5. Unless otherwise approved or directed, all plowing shall be performed with plow cutting edge perpendicular to the ground surface. Plow lines are to be backfilled and compacted, as required, as conduit installation progresses. All plow areas are to be backfilled before work is suspended for the day. Follow up restoration work will be required whenever settlement or erosion is observed. In the event of equipment breakdowns, severe weather, or railroad emergencies that preclude completing and closing excavations or disallow complete removal of equipment or materials, the areas are to be surrounded with orange construction fence to the satisfaction of the CSXT representative. Flashing construction barricades may be required if the sites are in or near walk ways, switches, signal control cabinets, or services roads used by CSXT personnel during night time hours. Excavations shall comply with OSHA requirements and be promptly backfilled and compacted in accordance with the drawings and specifications approved by the CSXT Chief Engineer, refer to Attachment No. 7. 6. Fouling of the track, ties and ballast will not be permitted. Approved ballast stone shall be available on the project at all times. Ballast contaminated or disturbed shall be replaced and/or reshaped immediately. 6 All obstructions located within 15 feet of the center of the near track or on or adjacent to the walk areas, switches, and signal control devices and cabinets are to be removed by the end of each workday. Conduit at the end of plow lines, directional bores, and trenches shall be cut off and buried as the work progresses. In the event that it becomes necessary to leave exposed ends or sections of conduit due to emergencies or inclement weather, they are to be surrounded with orange construction fences until they are connected or buried. Messages are to be sent to the CSXT dispatcher advising of potential crew or operational hazards. Casings and directional bore holes that have failed and are abandoned shall be sealed to prevent them from becoming conduits for drainage. Excavations associated with abandoned casings and bores are to be backfilled and compacted as shown in the specifications. The telecom owners are responsible for clearing and grubbing vegetation that conflicts with the construction and disposal of the debris off the right of way. 7.

U-14 -3- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - - ------------------------------------------------------------------------------ A -- Purpose ------------ A-1 These recommended practices are for construction and maintenance of communication lines crossing the tracks and associated parallel communication lines of steam and electrified railroads, except street railways. A-2 Where any requirements of this specification do not meet municipal or state requirements, such municipal or state requirements shall govern. B -- Definitions ---------------- B-1 Communication Lines: Communication lines as used in this manual part mean telegraph, telephone and other communication wires and cables and their supporting or containing structures which are located outside of buildings and are used for public or private communication service and which operate at not exceeding 400 volts to ground or 750 volts between any two points of the circuit, and the transmitted power of which does not exceed 150 watts. For such communication wires, when operating at less than 150 volts between wires or to ground, no limit is placed on the capacity of the system. B-2 Interlocking, automatic signal and other similar wires (not including electric light and supply wires), which operate at not exceeding the voltage and power requirements of communication wires, should be classed as communication wires. B-3 Communication circuits used exclusively in the operation of supply lines should, in general, be considered as supply circuits of the highest voltage to which they are exposed, and should be constructed in accordance with Manual Part 7-1 (Recommended Practices for Crossings of Electrical Supply Lines and Facilities of Railroads), but in no case need the communication conductors meet the requirements for supply conductors in excess of 8,700 volts between conductors. B-4 Where, however, such communication circuits are below the supply conductors in the operation of which they are used, at all points throughout their length or throughout the section in which the railroad crossing occurs, provided such section of the communication circuits is isolated from the remainder of the system by transformers or other means, -4- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ they may be considered as ordinary communication circuits and so constructed, if either of the following conditions obtain: (a) Such communication circuits occupy a position below all other conductors or equipment or other lines at crossings, conflicts, or on commonly used poles throughout the section to which reference is made. (b) Such communication circuits are protected by fuseless lightning arresters, drainage coils, or other suitable devices to prevent the communication circuit voltage form normally exceeding 400 volts to ground. B-5 Supply Lines: Electrical supply lines mean those conductors and their necessary supporting or containing structures which are located entirely outside of buildings and are used for transmitting a supply of electrical energy. B-6 Except as specified in Paragraphs B-4 and B-7, communication and railway signaling wires exceeding the voltage or power limitations specified in Paragraph B-1, are supply lines within the meaning of this manual part and should be so constructed. B-7 Circuits used for supplying power solely to apparatus forming part of a communication system may be run either in open wire or cable as follows: (a) Where run in open wire, such circuits should have the strength of construction, clearances, insulation, etc., prescribed for communication or supply circuits of the voltage concerned. (b) Where run in effectively grounded continuous metal sheath cable or in cable which is attached to effectively grounded suspension strand by means of metal rings or spirally wound lashing wire, the strength of construction, clearances, locations, etc., prescribed in this manual part for communication cables should apply. B-8 Voltage of a Circuit: Voltage of a circuit means the highest effective voltage between any two conductors of the circuit concerned, except that in a grounded multi-wire circuit of 750 volts or less between any two conductors, it means the highest effective voltage between any wire of the circuit and that point or conductor of the circuit that is grounded. -5- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - ------------------------------------------------------------------------------- B-9 Minor Tracks: Minor tracks mean railroad tracks included in the following: (a) Spur tracks less than 2,000 ft. long and not exceeding two tracks in the same crossing span. (b) Narrow-gauge or other tracks on which standard rolling stock cannot, for physical reasons, be operated. (c) Tracks used only temporarily for construction or similar purposes for a period not exceeding one year. (d) Tracks not operated as a public utility, such as industrial railways used in logging, mining, etc. (e) By agreement between the parties at interest, other similar minor tracks than those listed under (a), (b), (c) and (d) above. B-10 Major Tracks: Major tracks mean any tracks not included under the definition of minor tracks. C-General C-1 Permits and Notices: A party planning to erect wires across the tracks of a railroad shall give to the Superintendent of Communication or other designated officer of the railroad, written notice at least 30 days in advance of starting construction. Such notice shall include information regarding the location and general plan of the crossing, clearances and other data indicated on Typical Communication Line Crossing Data Sheet, Appendix L, and on Figures 1B1-1, 1B1-3, 1B1-4 and 1B1-5, and any other pertinent information in sufficient detail so that it can be determined whether or not the proposed construction will conform to this specification. C-2 In cases where 30 days' notice is impracticable because of service demands or emergency, the parties concerned should cooperate to avoid unnecessary delay in the construction of the crossing. C-3 Marking Poles: Crossing poles should be plainly marked by means of stencils or metal characters showing the name, initials or trade mark of the owning company. Where lines are located on railroad right-of-way for at least three poles adjacent to the crossing and it is the standard practice of the owning company to so mark at least every fifth pole in the line, the above requirement should be considered as having been met. -6- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ C-4 Fire Hazard: Crossing poles or other supporting structures shall be located as far distant as practicable from inflammable structures and the space around the poles or other supporting structures kept free from inflammable material. C-5 Protection from Moving Vehicles: Supporting structures adjacent to traveled highways shall be located with a view to reducing, as far as practicable, the danger of being struck by moving vehicles. Structures which are exposed to abrasion by moving vehicles or to other damage which would affect their strength materially, shall be protected by guards. C-6 Inspection: The construction shall be subject to the inspection of the railroad company and shall comply with the requirements of this manual part. Defective material shall be rejected and replaced with acceptable material. C-7 All parts of the supporting structures of overhead crossings should be inspected at such intervals as are necessary to assure adequate maintenance. All defective parts shall be promptly restored to a safe condition and, with the exception of wood poles, should be replaced when they have deteriorated to 50% of their required initial strength. Wood poles should be replaced when they have deteriorated to two-thirds their required initial strength. (The ground line circumference of various classes and species of poles whose strengths have deteriorated to two-thirds their strength when new is given in Appendix G.) In the replacement inspection of treated poles where decay is usually internal, the extent of the decay shall be determined and evaluated in terms of external decay so that the tables in Appendix G may be applied. C-B Underground crossings should be properly maintained. Part I - Overhead Crossings D-General D-1 Relative Levels of Supply and Communication Wires: Every reasonable effort should be made in the construction or reconstruction of a crossing to arrange or rearrange the lines so that supply wires should be at a higher level than the communication wires. This does not apply in the case of trolley contact wires or their associated feeders, which must, of necessity, occupy a position below all other wires at the crossing. -7- Association of American Railroads Communication Manual 1989 Part 1-B-1 D-2 Where communication lines cross over tracks and a supply line in the same span, or where supply wires are carried in the lower position on the same crossing poles as the communication wires, the construction of the crossing should be as follows, depending upon the voltage of the supply circuits: (a) Where the supply line is open wire and the voltage does not exceed 750 volts ac or dc to ground, constructions should be in accordance with this manual part. (b) Where supply circuits of any voltage are carried in cable having effectively grounded continuous metal sheath or on effectively grounded suspension strand, the construction should be in accordance with this manual part. (c) Where the supply line is open wire or is in cable not meeting the requirements of (b) above and the voltage exceeds 750 volts ac to ground but does not exceed 5,000 volts between conductors (2,900 volts to neutral or ground), the construction should be in accordance with this manual part, except that the communication conductors should be not smaller than No. 6 AWG (0.162 in. in diameter) copper or No. 6 Stl WG (0.192 in. in diameter) steel, or wires the equivalent thereof. (d) Where the supply circuits involved are in excess of the ac voltage limitations in (c) above, or in excess of 750 volts dc to ground, the construction should not be made except with the approval of all parties concerned. D-3 Supply wires or cables carried on the poles supporting communication circuits crossing over railroad tracks should be constructed in accordance with the Manual Part 7-1 (Recommended Practices for Crossings of Electrical Supply Lines and Facilities of Railroads) For construction of signal supply circuits not in excess of 550 volts and 3,200 watts, located below communication wires Manual Part l-A-6 (Recommended Practices for Construction of Railroad communication Pole Lines). D-4 Protection of Metals Against Corrosion: All pole line hardware should be of material that will not corrode excessively under the prevailing conditions. Where galvanizing is used, it should meet the requirements of the specifications for galvanizing of the American Society for Testing & Materials. -8- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ D-5 Vertical Pull: The vertical distance from the top crossarm of a crossing pole to a straight line connecting the top crossarm of the next adjacent poles on either side of this crossing pole should not exceed the values given in Table D-l. Table D-l Recommended Vertical Pull Average Length of Two Allowable Vertical Adjacent Spans in Feet Distance in Feet - - - ---------------------- ---------------- Less than 100 8 101 to 130 10 131 to 150 12 Over 150 14 D-6 Length of Crossing Span: The crossing span should, where practicable, not exceed 100 ft. in the heavy loading district, 125 ft. in the medium loading district and 150 ft. in the light loading district. Where practicable, the adjacent spans should not exceed the length of the crossing span by more than 50%. D-7 Where practicable, the supports for the crossing and next adjoining spans should be located in a straight line. D-8 The crossing and each adjoining span should be kept free from decayed trees and as far as practicable from overhanging trees, which might fall into the line. E-Clearances E-l General: The conditions under which all clearances are specified are 15.5C(60F) and no wind. Clearances should be measured between the nearest parts of the objects concerned. The clearances required by this section should be maintained at not less than the specified values. E-2 Side Clearances from Rails: Poles or towers supporting the crossing span should, where practicable, be so located as to provide a minimum horizontal clearance of 17 ft. from the nearest track rail and a minimum horizontal clearance of 8 ft. between the nearest track rail and any crossarm, guy or other attachment. Where it is impracticable or undesirable to provide these clearances, they may be reduced if the approval of the railroad concerned is obtained. Where necessary to provide safe operating conditions, which require uninterrupted view along the tracks for signals, signs, etc., the parties concerned should cooperate to provide greater clearances than those specified above. -9- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - - ------------------------------------------------------------------------------ E-3 Vertical Clearance Above Rails for Fixed Supports: The vertical clearance between the lowest wire, guy, or cable and the top of rail should be not less than given in Table E-l. Table E-l Recommended Vertical Clearance Above Rails Vertical Clearance in Feet For Wires............... 27 (a) (b) For guys, or cables carried on suspension strands. 25 (b) (a) Where the wires are paralleled on the same street or highway by a trolley contact conductor at a lower level, this clearance may be reduced to 25 ft. (b) Where agreed to by the railroad concerned, in special situations, less clearance may be provided if safety will not be decreased thereby. E-4 The clearances specified in Paragraph E-3 are applicable for crossing span lengths up to 175 ft. in the heavy loading district, 250 ft. in the medium loading district, and 350 ft. in the light loading district. Where crossing span lengths greater than these are involved, the clearances should be increased in accordance with Paragraph E-6 (a). E-5 Vertical Clearances Between Wires Not on the Same Supporting Structures: The vertical clearances between conductors of the crossing span and conductors of other lines should be not less than the values shown in Table E-2. These clearances apply under the following conditions: (a) Where the conductors at the upper level have fixed supports (pin or strain type insulators) or are supported on suspension type insulators in a suspended position at both supports, or are arranged so that they are restrained from displacement toward the crossing. (b) Where the length of the span of the conductors in the upper position is not greater than 175 ft. in the heavy loading district, 250 ft. in the medium loading district, or 350 ft. in the light loading district. -10- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ Notes for Table E-2 (a) These clearances apply also to inverted levels. (b) Except where neutral conductors of primary supply circuits are concerned, a clearance of 2 ft. is permitted where the supply conductor is above the communication conductor, provided the crossing is not within 6 ft. of any pole concerned in the crossing and the voltage to ground of the supply conductor does not exceed 300 volts. (c) This clearance should be increased to at least 6 ft. above trolley contact conductors of more than 750 volts to ground. This increased clearance should also be provided over trolley contact conductors of lower voltage, unless the crossover conductors are beyond reach of a trolley pole leaving the trolley contact conductor, or are suitably protected against damage from trolley poles leaving the trolley contact conductor. (d) A conductor which is effectively grounded throughout its length, such as a multi-grounded neutral wire, and is associated with a circuit of 750 to 15,000 volts between conductors, may have the clearances specified for open supply wires of 0 to 750 volts between conductors. (e) This clearance should be increased to 6 ft. where the supply wires cross over the communication line within 6 ft. horizontally of a communication pole. (f) This clearance should be increased to 4 ft. where communication cables cross over open supply service wires. (g) Where the required clearance is 2 ft., and where conditions are such that the sag in the upper conductor would increase more than 1.5 ft. at the crossing point, under full load conditions, the 2 ft. clearance should be increased by the amount of sag increase less 1.5 ft. (h) Multi-grounded wye circuits not exceeding 8,700 volts to ground may have a 4 ft. clearance if the lowest supply wire at the crossing is not lower than a straight line joining the points of support of the highest communication conductor, provided the crossing does not occur within 6 ft. horizontally of a communication pole. -11- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - - ------------------------------------------------------------------------------ TABLE E-2 Recommended Minimum Vertical Clearance In Feet Between Wires Not on the Same Structures (All voltages are between wires, except where otherwise stated,or for trolley contact wires where voltages are to ground.) Nature of Wires at Higher Level (a) Open supply wires, 0-750 volts; supply Guys, Communication cables, all voltages Open supply span wires, Nature of wires, cables having effectively wires and lightning wires crossed and suspension grounded metal sheath service drops protection Over (a) strand or suspension strand (d) wires 750 to 8,700 to Line wires Service 8,700 50,000 and cables drops Volts Volts Communication wires, cables and suspension strand 2(g) 4(b) (g) 2(g) 4(e) 6(h) 2 Trolley contact 4(c) ----- ----- ------ ------ 4(c) conductors Guys and span wires, lightning protection wires, supply service drops of 0 to 750 volts 2(f) 2 2 4 4 2(j) (j) Completely insulated sections of guys attached to supporting structures having no conductor of more than 8,700 volts may have less than this clearance from each other. E-6 Increased Clearances: Conductors in the upper position at the crossing, except guys or cables supported by suspension strand, should have greater clearances than given in Paragraphs E-3 and E-5 under the following conditions. The increases in (a), (b) and (c) below are cumulative. An example illustrating the method of determining the clearance between power wires and communication wires where an open wire communication line crosses over railroad tracks and under an open wire power line in the same span is given in Appendix K. -12- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ (a) For crossing spans longer than specified in Paragraphs E-4 and E-5 (b), clearances should be increased as follows: (1) The clearances given in Tables E-l and E-2 should be increased by the following amounts for each 10 ft. by which the crossing span length exceeds the limits specified in Paragraphs E-4 and E-5(b): Table E-3 Recommended Clearance Increase Increments Amount of Increase per 10 ft. Loading District Large Conductors Small Conductors* Heavy and Medium 0.15 ft. 0.30 ft. Light 0.10 ft. 0.15 ft. * A small conductor is a conductor having an overall diameter of metallic material equal to or less than the following values: Outside Diameter of Conductor (Inch) Material Solid Stranded All copper 0.160 0.250 Other than all copper 0.250 0.275 (2) If the crossing point is located elsewhere than at mid-span of the conductors in the upper position, the required clearance may be obtained by multiplying the clearance determined in (1) above by the appropriate reduction factors specified in Table E-4. The factors to be used in any case will depend upon the basic clearance required by Tables E-l and E-2, and in no case should the clearance, after the reduction factor has been applied, be less than such basic clearance. In applying these factors, the point of crossing in the case of a railroad crossing is the track rail which is farthest from the nearer support of the crossing span. In other situations, it is the location under the conductors of any topographical feature which is the determinant of the clearance. -13- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - - ------------------------------------------------------------------------------ Table E-4 Recommended Clearance Reduction Factors Distance from Nearer Support Basic Clearance of Crossing Span to Point of Crossing, in Percent of Crossing 4 Ft. 6 Ft. 27 Ft.

(c) Where the conductors of the line in the upper position at a crossing over a communication line are supported by suspension type insulators, the clearances should be increased by such an amount that the values specified in Table E-2 will be maintained in case of a broken conductor in either adjacent span, provided such conductor is supported as follows: (1) At one support by suspension type insulators in a suspended position and at the other support by insulators not free to swing (including semistrain-type insulators). (2) At one support by strain insulators, and at the other support by semistrain-type insulators. E-7 Clearance of Conductors of a Communication Line from the Supports of Another Line: Where conductors of a communication line are carried near a supporting structure of any other line and not attached thereto, they should have a clearance from any part of such structure not less than the larger value required by either (a) or (b) below: -14- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ (a) 3 ft., if practicable. (b) 6 in. plus 1 in. for each 2 ft. of the distance from the supporting structure of the line passed to the nearest supporting structure of the communication line. F-Loading Assumptions F-1 Three degrees of severity are recognized for the loading due to weather conditions and are designated, respectively, as heavy, medium and light loading. The classification of the United States on the basis of the districts in which these loadings should be considered to apply is shown on the loading map, Appendix A. Crossing wires and supporting structures should be designed for heavy, medium and light loading, dependent upon the district in which they are located. F-2 In those states in which detailed local districting of loading areas has been prescribed by state administrative authority, this districting should be employed in lieu of that given in Appendix A. Where such districting has not been prescribed, detailed districting or different loading assumptions from those given in this specification may be employed where agreed to by all parties concerned, including such administrative authority as may have jurisdiction. F-3 The specific transverse and longitudinal loadings which should be assumed in determining the size of poles or the strength of guys in each of the loading districts are indicated below: (a) Transverse Loading (Poles and Side Guys): (1) Heavy Loading: A horizontal wind pressure at right angles to the direction of the line of 4 lb./sq. ft. upon the projected area of the cylindrical surfaces of all supported conductors and cables, together with their supporting suspension strand when covered with a layer of ice 1/2-in. in radial thickness and on surfaces of poles without ice covering. For supporting structures, other than unguyed poles at crossings over major tracks, carrying more than 10 wires, not including cables supported by suspension strand, the transverse load due to the open wires should be calculated on two-thirds of the total number of such wires, with a minimum of 10 wires. -15- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - - ------------------------------------------------------------------------------ (2) Medium Loading: A horizontal wind pressure at right angles to the direction of the line of 4 lb./sq. ft. foot of the projected area of cylindrical surfaces of all supported conductors and cables, together with their supporting suspension strand, when covered with a layer of ice 1/4-in, in radial thickness and on the surfaces of the poles without ice covering. For supporting structures, other than unguyed poles at crossings over major tracks, carrying more than 10 wires, not including cables supported by suspension strand, the transverse load should be calculated on 2/3 of the total number of such wires, with a minimum of 10 wires. (3) Light Loading: A horizontal wind pressure at right angles to the direction of the line of 9 lb./sq. ft. upon the projected area of cylindrical surfaces of all supported conductors and cables, together with their supporting suspension strand, and poles, without ice covering. (b) Longitudinal Loading (Poles and Head Guys): The longitudinal loading should be assumed equal to a pull in the direction of the crossing of all open wire conductors supported, the pull of each conductor being taken as 50% of its ultimate strength in the heavy loading district, 33-1/3% in the medium loading district, and 22-1/4% in the light loading district. G-Poles G-1 Material: Wood poles should be of suitable and selected timber free from observable defects that would decrease their strength or durability. Poles of Northern White Cedar, Western Red Cedar, Chestnut, Southern Pine, Lodgepole Pine and Douglas Fir shall meet the requirements of the American National Standards Institute for poles of these species. For convenience, tables giving the dimensions of various classes and lengths of these species of poles, ANSI Standard 05.1-1987(Specifications and Dimensions for Wood Poles) are given in Appendix J. In the absence of specifications covering other species of poles, they should be considered on the basis of the ANSI standard for the species of pole having the nearest equivalent ultimate fiber stress. A table giving the ultimate fiber stresses of the species of poles in more common use in communication plant is included in Appendix H. The use of treated poles is recommended where practicable, but is not required, except in the case of timbers subject to rapid decay. -16- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ G-2 Sizes: Poles should be of a size not less than the class specified in Table G-l for the corresponding number of wires carried. If guys are omitted, poles must be of sufficient strength to meet the requirements specified in Paragraph Q-9. Table G-1 --------- Recommended Minimum Class (ANSI Classification) ----------------------------------------------- 10 Wires 11 to 20 21 to 40 Over 40 or less Wires Wires Wires Heavy and Medium Loading Districts 7 6 5 4 Light Loading District 7 6 6 5 G-3 Gains: Gains should not be cut to a depth of more than 1/2-in. G-4 Setting: Table G-2 specifies the minimum depth of setting for unguyed poles in average soil and in rock. G-5 Where crossing poles are head and side guyed, the depth of setting of poles normally employed by a constructing company in the construction of its lines may, in general, be used. However, in no case should the depth of setting of a pole at a crossing be more than 1 ft. less than the depths given in Table G-2, where the pole is set in earth or more than 1/2-ft. less when set in rock. G-6 Where soil conditions are such that the above depths of setting will not develop the strength of the pole, the pole should be set to an additional depth or other means used to properly secure the pole. G-7 Pole Mounts: Where a crossing pole is to be set on surface rock, a concrete bridge abutment, or other masonry or stone structure, approved pole mounts may be used. G-8 Spliced Poles: Spliced poles should not be used to support the crossing span. G-9 Stub Reinforced Poles: Stub reinforced poles should not be used at crossings over major tracks. At crossings over minor tracks, the use of stub reinforcements is permitted, provided: -17- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - - ------------------------------------------------------------------------------ Table G-2 Recommended Minimum Depth of Setting for Unguyed Poles Length of Depth in Feet in Average Soil for Different Classes of Poles Depth in Feet Pole in Rock in Feet Class 1 And 2 Class 3 And 4 Class 5 And 6 Class 7 All Classes 16 ----- ----- 4 3-3/4 3 18 ----- ----- 4-1/4 4 3-1/4 20 4-3/4 4-1/2 4-1/4 4 3-1/4 22 5 4-3/4 4-1/2 4-1/4 3-1/2 25 5-1/2 5-1/4 4-3/4 4-1/2 3-3/4 27 5-3/4 5-1/2 5 4-3/4 4 30 6 5-3/4 5-1/4 5 4-1/4 35 6-1/2 6 5-1/2 5-1/4 4-l/2 40 6-3/4 6-1/4 5-3/4 5-1/2 4-3/4 45 7 6-1/2 6 5-3/4 5 50 7-1/4 6-3/4 6-1/4 6 5-1/4 55 7-1/2 7 6-1/2 ----- 5-1/2 60 7-3/4 7-1/4 6-3/4 ----- 5-3/4 65 8 7-1/2 7 ----- 6 70 8-1/2 8 7-1/2 ----- 6 75 9 8-1/2 8 ----- 6 80 9-l/2 9 8-1/2 ----- ----- 85 10 9-1/2 9 ----- ----- 90 10-1/2 10 9-1/2 ----- ----- -18- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ (a) The pole above the ground line is in good condition and is of sufficient size to develop its required strength. (b) The stub should have a ground line circumference at least as great as would be required for a new pole in the same location. (c) The stub should be set to a depth at least as great as that required for the pole being stubbed. (See Paragraph G-4.) (d) The stub should be attached to the pole by a method which will develop at all times the required strength of the pole. G-10 Stubs should, in general, be set at the side of the pole in a plane perpendicular to the direction of the line. Where the direction of the line changes at the pole being stub reinforced, the stub should be at the side of the pole in a plane bisecting the angle of the corner and in the direction of the corner pull. Where head guys are omitted, as permitted in Paragraph Q-9, the stub should be set on the track side of the pole in line with the crossing span. H-Crossarms and Brackets H-1 Wood crossarms supporting the crossing span should be of fir, treated yellow pine or other suitable timber. They should have a nominal cross-section of not less than the values given in Table H-1.

H-3 Double crossarms should be provided on crossing poles and shall be attached to the pole by means of a 5/8-in. crossarm bolt. Double crossarms longer than two-pin should be equipped with double arming bolts at a point near each end of the crossarms. H-4 Wood pole brackets may only be used at crossings over minor tracks and should be in duplicate so as to afford two points of support for each conductor. H-5 Single metal brackets, drive hooks or fixtures may be used to support distributing wire at railroad crossings provided such bracket, drive hook or fixture and the attachment of the wire thereto is such as to withstand the ultimate breaking strength of the wire. J-Crossarm Braces J-1 Crossarms and buckarms, except two-pin crossarms, should be so braced as to safely support the loads to which they may be subjected in use, including lineman working on them. This strength may be obtained by the use of one pair of crossarm braces. Steel crossarm braces should have a cross section of not less than 1/8-in. by 1-1/8 in. and a length not less than 20 in. J-2 The braces should be attached to the pole by a drive screw not less than 1/2-in. by 3 in. and to the crossarm by bolts 3/8-in. in diameter. K-Pins K-1 Insulator pins should have strength sufficient to withstand the loads to which they may be subjected. Steel or iron pins should have a diameter of shank not less than 1/2 in. Wood pins shall be sound and straight grained with a diameter of shank not less than 1-1/4 in. L-Insulators L-1 Each insulator should be of such pattern, design and material that, when mounted on its pin, it will withstand, without injury and without being pulled off the pin, the ultimate strength of the conductor which it supports. L-2 Each conductor (not including paired wire) unless dead-ended, should be tied to two supporting insulators in such a manner that they will securely hold the conductor to its supporting insulators at each crossing pole. -20- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ M-Tie Wires M-1 A type of tie should be used which will develop the greatest practicable holding power without injury to the line conductors. N-Conductors N-1 Conductors should be of material or combinations of materials which will not corrode excessively under the prevailing conditions. N-2 Conductors of material other than those specified in Table N-1 should be of such size and so erected as to have a mechanical strength not less than that of the sizes of copper conductors specified in Table N-1 N-3 The minimum allowable sizes of conductors in a span crossing over a railroad which does not in the same span also cross over supply conductors in excess of 750 volts to ground, should be as given in Table N-1.

N-4 Paired or single distributing wires without a suspension strand should in no case be used for spans longer than 100 ft. in a heavy loading district, 125 ft. in the medium loading district, and 150 ft. in the light loading district. Each wire of a pair not supported by a suspension strand should have an ultimate strength of not less than 170 lb. Single distributing wires not supported by suspension strand should have an ultimate strength of not less than 340 lb. -21- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - - ------------------------------------------------------------------------------ N-5 Splices should, so far as practicable, be avoided in the crossing and adjacent spans, unless they are of such a type and so made as to have a strength substantially equal to that of the conductors in which they are placed. Taps should be avoided in the crossing span where practicable, but if required, they should be of a type which will not impair the strength of the conductors to which they are attached. P-Sags P-1 Table P-1 specifies recommended sags for wires shown in Table N-1. Where, however, the wires in the communication line are strung in accordance with recognized practices, the stringing tensions employed in the line, generally will be satisfactory in the crossing span.

Q-2 Side Guys: Poles supporting the crossing span should be side-guyed with guys having strengths specified in Appendix B, except as provided in Paragraphs Q-9 and Q-l0. The strength specified in this appendix may be obtained by using various combinations of standard guys, which, when taken together, will give strength at least as great as that specified. Q-3 For the purpose of side-guying, aerial cables and their suspension strands should have the wire equivalents given in Table Q-1. Table Q-1 Recommended Wire Equiva1ents Equivalent Number of Open Wires Diameter of Cable Heavy Loading Medium Loading Light Loading District District District Less than 1-1/4 in. 3 4 10 1-1/4 to 2-1/4 in. 4 5 15 Over 2-1/4 in. 5 6 20 -23- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - -------------------------------------------------------------------------------- Q-4 Head Guys: Poles supporting the crossing span should be head-guyed away from the crossing span with guys having strengths specified in Appendix C, except as provided in Paragraph Q-9. The strength specified in this appendix may be obtained by using various combinations of standard guys, which, when taken together, will give strength at least as great as that specified. For lines carrying both open wire and aerial cable, head guying need be provided only for the number of wires in excess of 10 if the cable is supported by a 6,000-lb. suspension strand or for the number of wires in excess of 20 if the suspension strand is 10,000-lb. or stronger. Q-5 Head guys should be installed so as not to increase tension in the crossing span. In order to facilitate the installation of the head guys, a section of 6,000-lb. strand may be placed between the crossing poles so as to provide an additional support for pulling up the head guys. Q-6 Guying at Corners and Terminals: Where the line terminates or changes direction or has substantially unbalanced tension at any crossing support, such additional guying as may be necessary should be provided to take care of the additional load. Q-7 Where a line crossing a railroad changes direction more than ten degrees at either crossing support, the side guy within the angle may be omitted and the head guy, if required, should be placed in the direction of the adjacent span unless the angle of turn is greater than 60 degrees. Where the angle is greater than 60 degrees, the head guy should be placed in a direction away from the crossing span. Q-8 Corner guys should conform to standard guying requirements unless the guying prescribed in Appendix B is greater, in which case the latter guying shall be provided. Q-9 Omission of Guys: Guys may be omitted in the following cases: (a) Side guys may be omitted where the poles when new will not be stressed to more than 25% of their ultimate strengths, when subjected to the transverse load specified in Paragraph F-3 (a), except as otherwise permitted in Paragraph Q-10. The maximum number of wires which can be carried by poles of various classes to meet this requirement is given in Appendix D. (b) Head guys may be omitted where the poles when new will not be stressed to more than 66-2/3% of their ultimate strengths when subjected to the longitudinal load -24- Association of American Railroads Communication Manual Part 1-B-1 1989 - - ------------------------------------------------------------------------------- specified in Paragraph F-3 (b). The maximum number of wires of various sizes which can be carried by poles of various classes to meet this requirement is given in Appendix F. Q-1O Where a communication line paralleling a railroad track on the right-of-way of the railroad crosses any of the minor tracks listed under Subparagraphs (a), (c), (d) and (e) of Paragraph B-9, the side guys may be omitted, provided the crossing poles when new will not be stressed to more than 33-1/3% of their ultimate strengths when subjected to the transverse load specified in Paragraph F-3 (a). The maximum number of wires which can be carried by poles of various classes to meet this requirement is given in Appendix E. Q-11 If, however, under the conditions stated in Paragraph Q-l0, there is an angle in the line at either crossing pole, corner guys sufficient to withstand the unbalanced load on such poles should be installed. Head guys may be omitted unless conductor tensions are not balanced at one or both poles due to the dead-ending of any of the wires. Where conductors are dead-ended, guys of strengths specified in Appendix C should be provided. Q-12 Guying in Special Cases: Where, on account of physical conditions, it is impracticable to side guy the crossing poles, as specified in Paragraph Q-2, or to provide the strength of an unguyed pole specified in Paragraphs Q-9 and Q-l0, the requirements may be met by head-guying and side-guying the line as near as practicable to the crossing, provided the line is approximately straight and the intermediate poles are not of a class lower than those specified in Paragraph G-2 and that a strand of strength equivalent to the load in pounds for which head-guying is required, is run between the two guyed poles. Where such guying is employed, it should meet the requirements of paragraphs Q-2 to Q-5, inclusive, and should be applied at a distance not exceeding 500 ft. from the nearest crossing pole. The strand should be attached to the guyed poles close to the point at which the head guys are attached, and should be securely attached to every pole between the guyed poled. Q-13 Guy Leads: Guy anchors should, where practicable, be located so that the horizontal distance from the ground line of the pole to the guy or guy rod will be not less than the height above ground of the attachment of the guy to the poles for head guys, and not less than one-third that height for side guys. The guys should be attached as near to the center of the load as practicable. (See Figure 1B1-2 for method of measuring guy lead and height.) -25- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - ------------------------------------------------------------------------------- Q-14 Methods of Anchoring Guys: The anchorage for guys shall in all cases be adequate to develop the required strength of the guys attached to them. Guys should preferably be attached to anchors set in earth or secured in rock. Where this is impracticable, guys may be attached to stubs or poles which are properly anchor guyed, or to buildings or other secure structures. Guys should not be attached to trees. Q-15 Guy Rods: Guy rods not smaller than those specified in Table Q-2 should be employed. The length of guy rods should be sufficient so that where the anchor is set to adequate depth, the eye of the rod will not be below the surface of the ground. Table 0-2 Recommended Minimum Size of Guy Rods Size of Guy Diameter of Guy Rod (Pounds) (Inches) 2,200 1/2 4,000 1/2 6,000 5/8 10,000 3/4 16,000 7/8 Q-16 Anchors: Where expandable or screw anchors or screw anchors are used, manufacturer's specifications must be followed as to depth and size of anchor. Q-17 Method of Securing Guy Strand: In securing guys, clamps, strand clamps or guy-grip dead-ends of suitable strength should be employed. A guy strand may be attached to the pole either by the wrapping method or by attachment to suitable eye bolts or approved connector. The size of the eye bolt or approved connector should be sufficient to develop the required strength of the guy. Q-18 Guards for Guys: When anchor guys are located so that persons or livestock may come into accidental contact with them, they should be equipped with suitable guards. Q-19 Pole Braces: Pole braces may be used in the place of guys called for in Paragraphs Q-2 to Q-8, inclusive, to provide equivalent strength. R-Suspension Strand R-1 Material: Suspension strands should be of galvanized steel or other material that will not corrode excessively under the prevailing conditions. -26- Association of American Railroads Communication Manual Part 1-B-1 1989 - - ------------------------------------------------------------------------------- R-2 Sizes: For spans of 150 ft. or less, Table R-l gives the minimum sizes of suspension strand to be used for supporting different sizes of serial cable. Table R-1 Recommended Minimum Sizes of Suspension Strand Weights of Cable in Suspension Strand (Nominal Pounds per Foot Ultimate Strength in Pounds) Less than 2.25 6,000 2.25 to 5 10,000 Exceeding 5 and less than 8.5 16,000 R-3 For spans exceeding 150 ft. or for heavier cables, a proportionately larger suspension strand or other proportionately stronger means of support should be used. R-4 Attachment to Poles: The suspension strand should be attached to the pole by means of standard cable suspension clamp secured by a bolt not less than 5/8 in. in diameter extending through the pole. Three-bolt suspension clamps should be used with 10,000 and 16,000 lb. suspension strand; single-bolt suspension clamps may be used for 6,000 lb. suspension strand. R-5 Where one or both of the crossing poles is a corner pole and the corner pull is in excess of 5 ft., suspension clamps with flared grooves or other means that will prevent sharp bends in the suspension strand should be employed. Where the cable is carried on the inside of the corner, reinforcing links or other equivalent means should also be used where the corner pull exceeds the values given in Table R-2. Table R-2 Size of Suspension Strand Pull on Corner 6M 15 ft. or over lOM 15 ft. or over 16M 10 ft. or over R-6 Safety straps, grade clamps, reinforcing bands or other equivalent devices which will prevent progressive stripping of cable from entering the crossing span should be placed at each crossing pole for cables 1-1/2 in. in diameter or larger. R-7 Where the suspension strand is dead-ended on a crossing pole, it may be attached by the wrapping method or by attaching it to a suitable eye bolt or approved connector. -27- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - - ------------------------------------------------------------------------------ The size of the eye bolt should be sufficient to develop the required strength of the suspension strand. R-8 Sags: Suspension strands for aerial cables should be strung so that when the cables are in place the sags will be not less than given in Table R-3. S-Cable Attachments to Suspension Strands S-1 Cables should be attached to the suspension strand in the crossing span by means of suitable metal rings or spirally wound lashing wire which will resist corrosion. The spacing of rings should not be greater than indicated in Table S-1. The spirals of lashing wire should be so spaced that they will safely support the cable and prevent appreciable sagging between points of support. The metal rings or lashing wire should be so installed that the protective coating will not be damaged. Table S-1 Recommended Spacing of Cable Rings Weight of Cable in Spacing of Cable Rings Pounds per Foot in Inches Less than 5 20 5 to 8.5 15 Part II - Underbridge Crossings T-General T-1 Avoidance of Attachments: The line preferably should be so graded that it will be unnecessary to make attachment to the bridge structure. If, for any reason, it is impracticable to grade a cable line to pass under a bridge and it is undesirable to attach to the bridge, vertical runs may be made on poles adjacent to the bridge. T-2 Attachments: Unless approved by the railroad company, attachments to railroad steel bridges should not be made by devices that require the drilling or cutting of the bridge structure or the removal of rivets, and the attachments should be so made that wires, cables and suspension strand will not be in metallic contact with the bridge structure. T-2 Clearance from Abutments: The clearance of any conductor from the face of the abutment, when not attached thereto, should be not less than 3 ft. for steel bridges. Cables or paired wires and their suspension strand may be attached directly to the face of the abutment if located not less than 24 in. below the elevation of the bridge seat, and they should provide suitable clearance for pedestrians, vehicles, etc., as may be necessary. -28- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ Table R-3 Recommended Minimum Sags in Aerial Cables (No Ice or Wind Loading) Average Weight of Size of Sags in inches for Spans Cables in Pounds Temp.

The clearance between any conductor not attached to the bridge and any portion of the bridge structure should preferably be not less than 1 ft., but in no case less than 6 in. Part III - Underground Crossings U-General U-1 Arrangement for Work: The work should be done at such time and in such a manner as not to interfere with the proper and safe use or operation of the property and tracks of the railroad company, previous arrangements having been made with the duly authorized representative of the railroad company for date and time of commencement. Where iron or mild steel pipes are used, as permitted in Paragraph U-7(d), consideration should be given to forcing or driving them under the roadbed instead of laying in an open trench. U-2 Location: The underground system on the railroad property should be so located as to be subject to the least practicable disturbance. Railway tracks and underground structures, including catch basins, gas pipes, etc., should be avoided where practicable. The manholes, pull boxes, and terminals should, where practicable, be located away from the roadbed. -30- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ U-3 Side Clearance from Rail: Where underground conduit construction terminates at terminal poles, the side clearance of such poles from the nearest track rail should be as provided in Paragraph E-2. Where manholes, handholes, etc., are employed, which project above the surface of the ground, the side clearance, unless physical conditions prevent, shall be not less than 17 ft. from the nearest track rail, except that at sidings, a clearance of 7 ft. may be allowed. At loading sidings, sufficient space shall be left for a driveway. U-4 Clearance Below Base of Rail: The top of all conduit protection, except as specified in Paragraph U-8 should generally be located at a depth of not less than 48 in. below the base of rail. Where this is impracticable, or for other reasons, this clearance may be reduced by agreement between the parties concerned. In no case, however, should the top of the conduit protection extend higher than the bottom of the ballast section which is subject to working or cleaning. U-5 Where unusual conditions exist or where proposed construction would interfere with existing construction, a greater depth than specified above may be required. U-6 Arrangement of Conduit System: The arrangement of ducts in the conduit system contemplated under this specification should consist of not more than four ducts of vitrified clay, four impregnated fiber ducts or three creosoted wood ducts in width. Where other arrangements are contemplated, additional strength of construction and protection may be required. U-7 Protection of Ducts: Ducts extending under the roadbed section of the right-of-way should be protected under the roadbed section as specified below and for a distance of at least 6 ft. beyond each outside rail. In other sections of the right-of-way, concrete, creosoted plank or other forms of protection should be provided where necessary to prevent injury to the conduit system. (a) Vitrified Clay Ducts: The ducts should be laid on at least 4 in. of concrete with at least 3 in. of concrete on the top and sides. (b) Impregnated Fiber and Other Tubular Composition Ducts: The ducts should be completely encased in concrete. The encasement should be at least 4 in. thick on bottom and at least 3 in. thick on top and sides. (c) Creosoted Wood Ducts: The ducts should be protected on the top and bottom by means of creosoted wood plank not less than 1-1/2 in. in thickness or by 3 in. of concrete. -31- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - - ------------------------------------------------------------------------------ (d) Iron or Mild Steel Pipes: Such pipes should normally be encased in concrete as provided in (b) above. However, where physical or chemical conditions will permit, a conduit system consisting of a group of not more than four iron or mild steel pipes not more than 4 in. in diameter may be laid beneath the roadbed without any form of protection. U-8 Where physical and chemical conditions will permit, a conduit consisting of not more than two iron pipes, not exceeding 4 in. in diameter, or two creosoted wood ducts not exceeding 6 in. square, or one or more cables of a type designed for burying directly in the earth may be laid in the ground beneath railroad tracks without any form of protection at a minimum depth of 48 in. below the base of the rail, unless the worked ballast section of the roadbed exceeds 18 in., in which case the conduit shall be laid below the ballast section. Cables under main line tracks should preferably be installed in conduit to prevent disturbance to the roadbed at times of replacement. U-9 Excavation: The excavated material shall be so placed as not to interfere with traffic. Ballast material excavated should be kept separate and free from earth. U-10 Shoring: Where necessary to prevent caving, the sides of trench should be supported with suitable planks and bracing. No bracing shall extend above the base of the rail or be attached in any way to the rails or ties. U-ll Grading and Drainage: The trench should be so graded that it will have a fall of at least 3 in. in l00 ft. toward the lower manhole or terminal, or from an intermediate point toward both manholes or terminals, and the bottom of the trench should be graded evenly. Where conditions require, a sump or other suitable drainage should be provided for manholes. U-12 Backfilling: The trench should be backfilled with earth to the subgrade line and tamped. Track ballast shall be replaced under railroad supervision. U-13 Removing Surplus Material: All surplus material remaining after the work has been finished should be removed, and if disposed of upon railroad property, it should be under railroad supervision. U-14 Concrete: All concrete employed should be such that when tested in 6 by 12 inch cylinders after 28 days, it should withstand a compressive test of not less than 2,000 lb./sq. in. square inch without rupture. Concrete should be thoroughly tamped. -32- Association of American Railroads Communication Manual Part 1-B-1 1989 - - - ------------------------------------------------------------------------------ Appendix A: District Loading Map [DISTRICT LOADING MAP DIAGRAM] -33- Association of American Railroads Communication Manual 1989 Part 1-B-1 -

Assume the case in which the power line carries a single-phase, two-wire circuit of 6,900 volts between wires, the wires attached to pin-type insulators on wood crossarms and that each wire consists of two strands of solid copper and one strand of copper-covered steel, the overall diameter of which is 0.230 in. Assume also that the crossing is located in the heavy loading district and that the length of the power line span concerned is 255 ft. The method of determining the required clearance between the lowest power wire and the highest communication wire consists of the following steps: 1. Referring to Table E-2; the power line takes the classification of open supply wires, 750 to 8,700 volts and the basic clearance is, therefore, 4 ft. 2. Referring to Paragraph E-6(a); since the crossing is located in the heavy loading district, and the power line span exceeds 175 ft. in length, an increase in clearance is required. Referring to the second table in Subparagraph (1) of Paragraph E-6(a), the wire used in this example takes the classification of a "small conductor" since it is stranded, is other than all-copper and has an overall diameter less than 0.275 in. Referring now to the first table in this same subparagraph, it will be seen that the amount of clearance increase for a "small conductor" in the heavy loading district is 0.30 ft. for each 10 ft. by which the span length exceeds 175 ft. The span length of 255 ft. exceeds 175 ft. by 80 ft., so that the clearance increase is 8 multiplied by 0.30 ft., or 2.4 ft. The total clearance is, therefore, the sum of 4 and 2.4, or 6.4 ft. 3. This clearance is applicable if the communication line crosses under the power line at or near the middle of the power line span where the sags of the power wires will be greatest when they are loaded with ice. Since the increased sag of the power wires caused by ice loading is less near the power poles than at mid-span, the clearance need not be as great as 6.4 ft. if the point where the communication line crosses under the power line (crossing point) is other than at the middle of the power line span. To take account of this permissible decrease, another step is necessary. -68- Association of American Railroads Communication Manual Part 1-B-1 1989 - - ------------------------------------------------------------------------------- 4. Referring to Table E-4; assume that the distance from the nearest power pole to the center line of the communication line is 51 ft. or 20% of the length of the power line span. The corresponding reduction factor given in the table for a basic clearance of 4 ft. is 0.71. Multiplying this by 6.4 gives a net clearance of 4.5 ft. which is the clearance that should be provided under the conditions assumed. If this clearance had been less than 4 ft., the basic clearance of 4 ft. should have been provided in accordance with the requirements of Subparagraph (2) of Paragraph E-6 (a). 5. The above assumes that the supply wires cross over the communication wires at a distance of more than 6 ft. horizontally from the nearest communication line pole. In accordance with Note (e) of Table E-2, if this horizontal distance is less than 6 ft., the basic clearance used in the above computations should be 6 ft. and the clearance under the conditions assumed above would be 8.4 ft. at mid-span or 6.6 ft. at the 20% point. 6. The above takes care of the clearance increase required by Paragraph E-6 (a). The next step is to determine the further increase required by the voltage of the power circuit as given in Paragraph E-6 (b). In the case assumed, since the voltage is less than 50,000 volts, no increase is required and the clearance as determined in Step (d) or (e) above would meet the combined requirements of Paragraphs E-6 (a) and E-6(b). Had the voltage been 69,000 instead of 6,900 volts, the basic clearance from Table E-2 would have been 6 ft., the clearance due to span length would have been that determined in Step (e) above to which would be added 1/2 in. for each 1,000 volts that the voltage exceeds 50,000 volts. This increase would amount to 9-1/2 in., or 0.8 ft., and the total clearance would have been 9.2 ft. at mid-span, or 7.4 ft. at the 20% point. 7. The final factor which enters into the determination of the clearance is the method of support of the power conductors as given in Paragraph E-6(c). The object of this clearance increase is to insure that a total clearance is provided such that at least the basic clearance called for in Table E-2 will be maintained in the event that the power conductor is broken in the span adjacent to the crossing in those situations where the conductor is more or less rigidly supported at one crossing structure and at the other crossing structure is supported by suspension or other type insulators which are free to swing and thereby permit a large increase in the sag of the power wire in the crossing span. Where the power conductor is supported by pin-type insulators at both crossing structures, as assumed -69- Association of American Railroads Communication Manual 1989 Part 1-B-1 - - ------------------------------------------------------------------------------- in the example in this appendix, this effect is not present and no increase in clearance is required for this item. The same result would have obtained had the power conductor been supported by suspension-type insulators at both crossing structures. This effect is important only where the method of supporting the power conductor is such as not to permit the same freedom of movement of the conductor at one crossing structure as at the other. The determination of the increase in sag which would result from such dissimilar supporting arrangements is complicated and since it is a type of construction which will rarely be encountered where this specification is involved, it will generally be found preferable to obtain the information from the engineers of the company owning the power line rather than attempt to compute it. -70- Association of American Railroads Communication Manual Part 1-B-1 1989 - - -------------------------------------------------------------------------------- Appendix L Recommended Typical Communication Line Crossing Data Sheet A data sheet of the type illustrated below shall be filled out by the party planning to erect wires across the railroad and forwarded to the Superintendent of Communications or other designated officer, together with the plan and other pertinent information, as a part of the notice required by Paragraph C-1.

AVOIDANCE OF ATTACHMENTS The cable system preferably should be so graded that it will be unnecessary to make attachments to railroad bridge structures. II. ATTACHMENTS TO FIXED BRIDGES Unless separate written approval of the Railroad's Chief Engineer has been obtained, cable will be encased in steel conduit, and attachments to steel bridges shall be made with devices that do not require the drilling or cutting of the bridge structure or the removal of rivets. Attachments to each individual bridge shall be in accordance with drawings prepared by or for Utility and approved by the Railroad. Typical attachment drawings may be prepared for those types of bridges whose design and construction lend themselves to repetition of attachment method and detail. However, the Railroad shall make final determination as to the applicability of any typical attachment drawings to an individual bridge. III. ATTACHMENTS TO MOVABLE BRIDGES All attachments to movable bridges require separate written approval of the Railroad's Chief Engineer and will be made in accordance with requirements prescribed for that particular bridge by the Railroad. IV. TEMPORARY RELOCATION OF ATTACHMENTS Temporary relocation of cable systems attached to bridges will be made promptly and without cost to Railroad when necessary for Railroad to perform bridge maintenance. Notification will not be less than 30 days prior to date that relocation must be complete, except in case of emergency. The attachment requirements set forth by the Railroad will locate the attachment, to the extent possible, such that the occurrence of such temporary relocations will be minimized. V. NEW BRIDGES In the event that new railroad bridges are to be constructed along the right-of-way occupied by Utility and Utility desires to locate its cable facility on such bridges, provision for Utility cable will be incorporated into the bridge design. Costs of design, construction, and materials attributable solely to Utility's use of the structure, as well as costs of any temporary relocation of Utility's facilities during bridge construction, will be paid by Utility. EXHIBIT H EMERGENCY AND DISASTER RESPONSES In the event of an emergency or disaster which results in actual damage to Facilities or System or to Railroad's facilities or operations, or creates a situation wherein it is reasonably possible that such damage may occur, immediate contact shall be established between Railroad's Operations Center, and applicable division personnel, and Utility's Operation Center and applicable Area Representatives. Detailed procedures effectuating the above notification shall be mutually established. Railroad and Utility will fully cooperate with each other and coordinate their efforts to jointly and severally restore operation of their respective rail and communication systems, with each being solely responsible for all costs incurred in repairing its own facilities. In the event such cooperation results in one party incurring costs that are for the benefit of the other (e.g., Railroad providing railroad equipment to Utility), such costs shall be subsequently fully reimbursed. Utility will maintain emergency material and repair kits at various points throughout its System. Railroad shall have the right to establish priorities for making repairs which impact upon rail operations, but shall permit Utility to move forward in making repairs to Utility's System or Facilities when to do so would not impair rail operations.

In the event of any controversy, claim or dispute between Utility and Railroad referred to arbitration or mediation pursuant to this Agreement (hereinafter referred to as "Dispute"), the parties agree to use the procedure herein. B. The parties agree that the only circumstances in which a Dispute will not be subject to the provisions of this Exhibit are: (i) where a party makes a good faith determination that a breach of the terms of the Agreement by the other party will cause irreparable damage to the complaining party unless such breach is enjoined by a court of competent jurisdiction; or (ii) where one party has been made a party to a judicial proceeding, and the other party is an appropriate additional party to such proceeding. Breach of the Agreement will be deemed to cause irreparable damage if it is incapable of adequate redress if not promptly enjoined, so that a temporary or preliminary restraining order or other immediate injunctive relief is the only adequate remedy. If one party files a pleading seeking injunctive relief, and such pleading is challenged by the other party, and the injunctive relief sought is not awarded in substantial part, the party filing the pleading seeking immediate injunctive relief shall pay all the costs, attorneys' fees and expenses of the party successfully challenging the pleading. 1. Notice of Arbitration or Mediation. If the parties have not succeeded in negotiating a resolution of a Dispute within thirty (30) business days following the Trigger Notice (which period may be extended by mutual agreement of the parties), arbitration or mediation shall be conducted as set forth below. The Trigger Notice shall specify in reasonable detail the nature of the Dispute and comply with the procedures set forth in Paragraph 2 or Paragraph 3. 2. Arbitration Procedures. Arbitration shall be conducted in accordance with the then-current CPR Non-Administered Arbitration Rules (the "Rules"). The provisions of the Agreement shall control if they conflict with the Rules. Arbitration shall be before three (3) arbitrators. Each party shall appoint one (1) arbitrator within fifteen (15) business days following the commencement of the procedure by Trigger Notice above (which period may be extended by mutual agreement). Within fifteen (15) business days following their appointment, the two (2) arbitrators so selected shall appoint the third arbitrator, who shall serve as Chairman of the arbitration panel. The Chairman shall be an attorney at law admitted to practice in the United States and experienced in arbitration. The arbitrators shall determine issues of arbitrability in accordance with federal law, but may not limit, expand or otherwise modify the terms of the Agreement. Arbitration shall be governed by the United States Arbitration Act, 9 U.S.C. Sections 1-16, and judgment upon the award may be entered by any court having jurisdiction thereof. In addition, the following shall apply with respect to any arbitration conducted pursuant to this Appendix: (a) Costs/Fees. If either party submits a matter to arbitration, and provided that one of the parties prevails over the other, the arbitrators may award such prevailing party an amount equal to its reasonable attorneys' fees and expenses, experts' fees, and other reasonable costs and expenses that it has incurred in connection with the arbitration. Otherwise, each party shall be responsible for its own fees and expenses. (b) Remedies. Upon a showing of material breach of the Agreement, the arbitrators are empowered to award actual or compensatory damages, unless prohibited by applicable state law or the Agreement. The arbitrators may not award consequential, punitive or multiple damages; the parties expressly waiving any entitlement to such relief. (c) Location of Arbitration. The place of the arbitration shall be Jacksonville, Florida. (d) Confidentiality. The parties, their representatives, the arbitrators and any other participants in the arbitration shall treat all aspects of the arbitration as confidential, including but not limited to all documents, testimony, information or other things produced, inspected or otherwise 1 made available in connection with the arbitration. Neither the parties nor the arbitrators may disclose the existence, content or results of the arbitration, except as necessary to comply with applicable law or regulatory requirements. Before making any such disclosure, the party seeking disclosure shall give written notice to the other party, and shall afford such party a reasonable opportunity to protect its interests. In no event shall a disclosure necessary to comply with legal or regulatory requirements be deemed to waive the confidential nature of the disclosed information. (e) Discovery. The arbitrators shall permit and facilitate such discovery in accordance with Federal Rules of Evidence and Federal Rules of Civil Procedure, as they shall determine is appropriate under the circumstances, taking into account the needs of the parties, the relevance of the requested discovery to the matter in controversy and the desirability of making discovery expeditious and cost-effective. The parties agree that the following information shall not be subject to discovery in connection with the arbitration unless it is expressly authorized by the arbitrators upon a showing of substantial need by the party seeking discovery: (i) information relating to Railroad's agreements with any customers; (ii) information relating to Utility's cost structure, contribution or profits under third party usages allowed under the Agreement. 3. Mediation Procedures. Mediation is a voluntary process in which a neutral third party, who lacks authority to impose a solution, helps participants reach their own agreement for resolving a dispute or transaction. Utility and Railroad agree to act in good faith negotiation, with the jointly appointed mediator, to reach an agreement, utilizing the following basic roles of the mediator in the Dispute resolution: - urging participants to agree to talk; - helping participants understand the mediation process; - carrying messages between parties; - helping participants agree upon an agenda; - setting an agenda; - providing a suitable environment for negotiation; - maintaining order; - helping participants understand the problem(s); - defusing unrealistic expectations; - helping participants develop their own proposals; - helping participants negotiate; - persuading participants to accept a particular solution. (a) Mediation shall be held in Jacksonville, Florida. (b) Each party shall be responsible for its own attorney fees, and costs (including exhibits, witness fees, etc.), and shall each pay one-half (1/2) of the Mediator's fee(s). (c) The mediator shall be jointly selected as follows: (1) Railroad shall designate five (5) members from the listed panel of the U.S. District Court, Middle District of Florida as a Potential Mediation Panel; (2) Utility shall select one (1) of such Panel as the mediator; (3) If the selected mediator does not accept the mediation appointment, Utility shall designate an alternative, and continue until a selected mediator accepts the mediation appointment; (4) If none of the Panel accepts the appointment, Utility shall designate a new Potential Mediation Panel of five (5) from the list in Paragraph 2.(b)(1), and Railroad shall select one (1) of such Panel, as in Paragraphs (2) and (3). (d) The form of the Agreement to Mediate shall be as follows: 2 AGREEMENT TO MEDIATE Railroad and Utility, through their respective counsel, stipulate that: 1. The Dispute embodied in the Agreement stated is hereby submitted to mediation. 2. The parties have selected _________________________ to be the mediator in this case. 3.
