Any Dispute shall be attempted to be resolved first through amicable settlement discussions and each Party shall bear its own costs and attorney's fees of such settlement discussions.

In the event the Parties fail to reach a settlement of the Dispute pursuant to settlement discussions in accordance with Section 17.1.4, each Party (the "Complaining Party") shall have the right, to file suit in a court of competent jurisdiction in a neutral forum or upon mutual consent of the parties, to refer such Dispute for final resolution by binding arbitration in accordance with the rules of the American Association of Arbitration (the "AAA"); provided, however, that the non-Complaining Party shall only have the right to institute suit regarding the Dispute in a court of competent jurisdiction prior to the commencement of the initial arbitration hearing, and upon filing such suit, the arbitration proceedings shall be deemed terminated. 17.1.6 Binding Effect. The Parties acknowledge and agree that (i) the award in any arbitration shall be final, conclusive and binding on the Parties and (ii) any such arbitration award be a final resolution of the Dispute between the Parties to the same extent as a final judgment of a court of competent jurisdiction. 17.1.7 Arbitration Process.

Within thirty (30) days after the deliverance of the notice of arbitration, each Party must select one (1) arbitrator and a third arbitrator will be selected by agreement of the two (2) arbitrators selected by the Parties. If either Party fails to select an arbitrator or there is no agreement on the selection of the third arbitrator, AAA will select such arbitrators. (C) Transcripts and Evidence. Both Parties shall cause a written transcript of all proceedings and testimony to be kept and the cost of such transcript shall be borne equally by the Parties pending the final award. All documents that either Party proposes to offer in evidence, except for those objected to by the other Party, shall be deemed to be self-authenticating. (D) Applicable Law. The arbitrators shall determine the claims and defenses of the Parties and render their final award in accordance with the governing law of this Agreement as set forth in Section 18.5. Notwithstanding anything set forth in the Arbitration Rules to the contrary, the provisions of this Section 17 shall govern any arbitration proceeding brought in relation to this Agreement or the transactions contemplated thereby. (E) Sanctions. The Parties acknowledge that, in addition to any other remedy allowed or specified in or under the AAA rules, the failure of a Party to comply with any interim, partial or interlocutory order, after due notice and opportunity to cure such non-compliance, may be treated by the arbitrators as a default and all or some of the claims or defenses of the defaulting Party may be stricken and partial or final award entered against such Party, as determined by the arbitrators in their sole discretion. (F) Limitation on Awards. Arbitrators may not award (i) incidental, consequential or punitive damages in the resolutions of any Dispute and the Parties hereby waive all rights to and claims for monetary awards other than compensatory damages, (ii) any other right or remedy that contravenes the terms and conditions of this Agreement, or (iii) except as provided in Section 3.2, termination of this Agreement.

Any arbitration award must be in writing and must contain findings of fact and conclusions of law upon which the arbitrators relied in making the decision relating to such award. (I) Attorney's Fees.

The ground system limits excessive voltages from various electrical conditions such as lightning and utility switching, and contributes to superior performance of the electronic equipment by reducing noise induction 1. Grounding Introduction Communications equipment shelters are subject to electrical noise and high-voltage surges. These transients occur predominantly in the common mode (line to ground), and are typically caused by lightning or power switching. 1.1 Lightning When lightning induced surges appear at the point of connection to a building (the service entrance), a high common mode potential is generated between the current carrying conductors and ground. This potential produces a flow of current that seeks a path to earth to complete the circuit. Lightning can easily induce a 3000-ampere transient into a power line. When this transient reaches a building, the building ground at the service entrance can rise to 60,000 volts (assuming a building earth resistance of 20 ohms). The reference potential for ground in the rest of the building would rise proportionately. In order to protect the building against these high voltage surges, it is important to establish a low resistance earth ground at the service entrance. The National Electrical Code (Article 250, Part 4) specifies that the grounding at a building's service entrance should have a resistance to ground of 25 ohms or less. The IEEE Green Book (Recommended Practice for Grounding, ANSI/IEEE Standard 142-1982) recommends that the ground resistance be less than 5 ohms. If the building contains highly sensitive electronic communications equipment, a ground resistance of 5 ohms or less is recommended if this value can be practically achieved with the given site conditions. 1.2 Types of Grounding There are two major types of grounding that should be considered when designing an electrical system: power distribution system grounding and telecommunications A-33 equipment grounding. 1.2.1. Power Distribution System Grounding The power distribution system pertains to the incoming AC service, service entrance equipment, power panels, and electrical conductors providing the power to various electrical/mechanical equipment. Grounding of the power distribution system is essential to: -- protect occupants from exposure to dangerous shock voltage -- provide a path for ground fault current -- limit excessive voltages due to lightning or utility switching Typical grounding components for the power distribution system include: -- grounding electrode at the service entrance -- ground bus in the power panel -- ground lugs in the other service entrance equipment such as the safety disconnect or transfer switch -- third wire grounding conductor for all the electrical equipment -- lightning and surge arresters. 1.2.2. Telecommunications Equipment Grounding Electronic equipment such as radio systems, telephone switches, battery chargers and rectifiers, uninterrupted power supply (UPS) equipment, and any other equipment that encloses or is adjacent to energized conductors require additional grounding. This sensitive electronic equipment must be protected from the following: -- excessive transients caused by lightning or utility switching -- degraded performance due to electromagnetic noise Equipment grounding frequently utilizes a ground ring encircling the interior of the shelter (halo ground ring). Ground lugs attached to the various equipment housings and racks are connected to the ground ring. Ground bars at the waveguide entry and at each section of the cable ladder are also tied to the ground ring. Multiple external drops connect the internal ground ring to the exterior site pound ring. 2. Grounding Practices 2.1. The Grounding Conductor In order to reduce inductance and surge voltages in a power distribution system, a ground path for protected devices should be provided. One method is to rely upon the conduit A-34 system to carry these transient currents. This is allowed by the National Electrical Code in Article 250-91 (b). The best method, however, is to include an extra conductor in the same conduit or raceway as the current carrying conductor. The grounding conductor should extend to the ground connection in the service entrance equipment. 2.2. Equipment Ground Wires When lightning strikes, it takes the path of least impedance (resistance and inductance). Cable bends increase inductance. Therefore, equipment ground wires should be large, and run straight for minimum inductance and voltage drop. The recommended bending radius is 6" when bends are unavoidable. Equipment ground wires should be separated from all other conductors, and should not be run through metal conduit unless the conduit and ground wires are bonded at both ends. 2.3. Bonding Even when the ground to earth connection's impedance of the service entrance is minimized and grounding conductors are used in the feeder and branch circuits, high transient voltages can still occur in the power distribution system as a result of utility power switching. An effective method of limiting this noise (especially common mode voltage differentials) is to bond all the equipment ground wires to a halo ground system that is connected to the site ground system and power distribution system ground. Bonding is the connection of all potential ground conductors (including racks, frames, cable ladder, conduits, metal enclosures, and exposed metallic members of the building structure) to each other. Bonding does not eliminate voltage drops since transient currents will continue to take the path of least inductance. However, the current is sufficiently distributed throughout the bonded system to reduce the voltage gradients in any area to levels that prevent personal injury or equipment damage. Proper bonding procedures produce cross connections of all equipment and structures. It provides many paths to ground from any one point. Since the bonded ground network does not form a part of the normal electrical power path, multiple inductive loops are not a concern. Only transient or fault currents can flow in the ground network. In addition to preventing the development of voltage gradients, cross connection reduces the system's susceptibility to high frequency noise. Since all conductors have some impedance, resonance will occur at some frequencies. At those frequencies, the impedance of the grounding conductor may be very high, and allow noise currents to develop increased voltage drops. By bonding the ground network, however, there may be other conductors nearby that are not resonating, and a low impedance path for the noise signal can be maintained. A-35 2.4. Faraday Cage A Faraday cage provides an EMI shield to further reduce noise. The cage usually consists of multiple conductors in a box like configuration. A halo ground system with multiple down conductors can act as a quasi Faraday cage, and give some low frequency shielding. When lightning hits the tower, the tower will pass the current to ground and radiate RF energy. A Faraday cage can reduce this energy by adding distance (as seen by the magnetic field) between the tower and the equipment shelter. The steel reinforcing in the concrete shelter walls can form a highly effective Faraday cage if bonded to the grounding system. The amount of shielding depends on the size and spacing of the welded wire fabric. Additionally, all rebar must be bonded together. 2.5. Site Ground System When a tower is struck by lightning, equipotential voltage rings form around the tower until the energy is diffused into the surrounding ground soil via the grounding system. The tower ground ring will disperse the energy away from the tower base or guy wires. The ground rods will transfer the energy deeper into more conductive soil layers. This is important to keep lightning surges out of the equipment shelter. Unless the energy is properly dispersed into the soil, the voltage will build up in the tower, and attempt to go to another, less desirable path. The equipment shelter is protected by a perimeter ground system that forms an equipotential plane. Also, ground rods should be driven into the soil at the following points: -- each corner of the shelter -- the service entrance -- the waveguide entry port -- each external halo ground drop -- every 10' (or less) along the exterior ground ring The shelter ground ring system should have a connection to the tower ground system just below the coaxial cable runs. A second connection between the two ground systems should be installed for redundancy. All metal work (waveguide bridge and supporting posts) should be bonded to the ring/radial ground system. 2.6. Grounding System Performance Check Test the original installation periodically to determine whether resistance is remaining constant or is increasing. An increase in resistance can be caused by several factors. A-36 In lower conductive soils, high electric fields can develop at the ends of the ground rods, which can cause arcing in the soil. This arcing can cause glassification around the rods, beginning at the tip, and working its way upward. This glassification of the silica in the soil acts as an insulator, severely impairing the grounding characteristics of the rod. If resistance increases over time to an undesirable level, reduce the resistance by adding electrodes or chemically treating the soil to increase moisture content. 2. Computing Resistance to Ground 3.1. Resistance to Earth The resistance of a grounding electrode is dependent on the: -- resistance of the electrode, -- contact resistance between the electrode and the soil, and -- resistance of the soil from the electrode surface outward as described by the geometry set up by the flow of current from the electrode to infinite earth. The first two resistances are negligible, and can be disregarded. The third resistance is larger and must be considered. Around a ground rod this resistance is the sum of the series resistances of virtual shells of earth, located progressively outward from the rod. The shell nearest the rod has the smallest circumferential area or cross section, so it has the highest resistance. Each successive shell has progressively larger areas, and thus, progressively lower resistances. For an 8-foot ground rod, the incremental increase in resistance decreases to nearly zero when the rods are spaced 16 feet apart. Therefore, when using multiple ground rods, the optimal spacing between rods should be double the length of the rod. 3.2. Resistance Calculations When computing resistance to ground, treat the tower grounding and the shelter grounding as two separate systems. Within each of these two systems are two subsystems. The shelter has a grounding ring and the grounding rods. The tower has a grounding ring, grounding rods, and occasionally, grounding radials. The IEEE Green Book provides several formulas for calculating the resistance to ground for several different systems. 4. Typical Grounding Configurations Several options are available when deciding on a ground system for a communication shelter, depending upon the soil conditions and thunderstorm activity of a particular site. The U.S. Weather Bureau publishes an isoplethic map of the United States showing the average number of days each year on which thunderstorms occur. Any area with an isoplethic level above 90 should be considered a high-risk area, and serious consideration should be given to providing a more A-37 stringent grounding system. 4.1. Ground Bar System In shelters where very little lightning protection is needed, a simple ground bar system can be used. A system of this type would consist of a single copper ground bar located under the waveguide port, telephone entry, or both, with an external drop to be connected to the external ground system. Transmission lines should be grounded to this ground bar. 4.2. Halo Ground System Pathnet shelters will use a halo ground system. This system includes a #2 AWG copper wire completely encircling the equipment room. The halo is located 3 to 6 inches below the ceiling. External drops are located at each corner of the shelter. Wall penetrations should be angled at 45 degrees to minimize bending. 4.3. External Ground System The external ground system for all shelters consists of ground rods placed at each corner of the shelter and 10' intervals along the ground ring, below the waveguide entry, and at the AC service entrance. The rods should be exothermically welded to a perimeter ground ring of #2 AWG solid tinned copper wire. (Tinned copper is recommended to reduce corrosion of the wire). The wire should be buried below the frost line (minimum 30", deep per NEC Sec 250-8(d)), and at least 24", away (measured horizontally) from the foundation. The ground ring should be bonded to the tower ground system at two locations, to the externally mounted ground bars under the waveguide ports and to the AC service ground as close as possible to the service entrance. 5.

A one hole copper ground lug will be used for equipment connections. An oxidizing preventative compound will be applied to all mechanical connections, and paint will be removed as necessary to insure positive bonding of all grounded equipment. All external, buried connections will be of the exothermically welded type. These include, but are not limited to, halo drops to ground rod, buried ground ring to ground rod, halo drops to ground ring, service entrance ground to ground rod. 5.1.4. Wire All equipment grounds will be #6 AWG. Circuit grounding conductors will be no more than two wire sizes smaller than the current carrying conductors of the same circuit (minimum #12 AWG). All external ground wire, including but not limited to the external ground ring and external halo drops, will be #2 AWG solid tinned copper. 5.2 Interior Grounding 5.2.1. Halo Ground The halo ground will consist of a minimum #2 AWG wire located 3" to 12", below the finished ceiling, and will completely encircle the equipment room. The wire will be green insulated stranded copper, bare stranded copper, or bare tinned solid copper. Each corner of the equipment room will have an omni-directional drop to the floor of the same wire size and type as the halo ring. Connection of these drops to the halo will be at least the defined minimum (see section 5.1.3). If solid tinned wire is used, the drop will be one continuous wire that is long enough to extend 8 feet beyond the exterior of the shelter. If insulated wire is used, the drop will extend to the floor, and then be connected in the same manner as the halo, to an 8 foot length of solid tinned wire of the same size. The exterior penetrations will be at 45 degree angles (to minimize ground drop bend radii) and approximately one (1) inch in diameter. 5.2.2. Waveguide Entry Ground Bar There will be a 1/4" x 4" x 20" (minimum) copper ground bar located outside the shelter approximately 6" below the waveguide entry plate (NEC Sec 800-33). This bar will be connected to the exterior ground ring exothermic weld. The grounding conductor will be of the same size and type as the halo ring. A-39 5.2.3. AC Service The AC service ground conductor will be bonded to the ground rod located at the service entrance. Ground lugs provided in all service entrance equipment will be bonded to the service ground conductor. The system ground and neutral will be bonded at one location, as close as practicable to the service entrance. All service grounding shall conform to Article 250 of the National Electrical Code. 5.2.4. Primary Surge Arrester There will be a surge protective device applied at the first piece of service equipment inside the equipment shelter. This device will be considered the primary surge protector. Conductors connecting the surge protective device will be as short as possible, and will contain no sharp bends or loops. The operating characteristics of the primary surge arrester will coordinate with the equipment surge withstand voltage capabilities. The surge arrester should be capable of suppressing up to 65kVA, be self restoring after operation, and may be equipped with a failure alarm over current protective device and visual status indicators. 5.2.5. Cable Ladder Cable ladder assemblies will be bonded to the halo ring with a #6 AWG or larger ground conductor. All cable ladder splices and junctions will be bonded on at least one side with a #6 AWG or larger conductor, and use grounding clips suitable for the purpose. Paint will be removed as necessary for an electrically sound connection. 5.2.6. Conduit Grounding Each conduit discontinuity, including but not limited to conduit couplings, junction boxes, light fixtures, and service equipment, will be provided with ground clamps to electrically bond the conduit. The bonding wire will be green insulated #6 AWG or larger. 5.2.7. Tower Light Controller Penetration There will be a 1-1/2" penetration cast in place near the waveguide entry port to allow for connection of the tower light controller. The penetration will be lined with a 1" PVC running thread to provide isolation between the interior and exterior conduit. The running thread will be connected to interior and waterproof exterior 6" x 6" junction boxes. A-40 5.3. Exterior Grounding 5.3.1. Ground Rods There will be driven ground rods located at each corner of the building, and at the AC service entrance and waveguide entry port. These rods will be made of copper clad high strength steel with minimum dimensions of 5/8" x 8'. The rods will be located at least 24" from the edge of the foundations, and driven such that the top of the rod is below the frost line of the installation site. The rods will be exothermically welded to the external halo drops. 5.3.2. Ground Ring There will be a buried horizontal wire completely encircling the equipment shelter. This wire will be solid tinned copper wire of #2 AWG or larger. The ground ring will not be closer than 24" from the shelter foundations, and will be exothermically welded to each ground rod. The ring will be buried 30" below grade or below the frost line of the installation, whichever is greater. The ground ring will be connected to the tower ground system from the ground rod located at the waveguide port to the nearest ground rod of the tower system. A second connection will be made from a rod at a corner of the shelter to an alternate rod of the tower. These connections will be made with a #2 AWG wire, or a wire of the same size as the tower ground ring, whichever is larger. 5.3.3. Testing The external ground system will be tested after installation, and its resistance to earth ground will be less than 10 ohms. It is recommended that tests be performed twice a year to insure ground system integrity. Biddle Instruments Model DET2/2 Digital Ground Tester, or equivalent, will be used for testing and all manufacturers' instructions will be followed.

A-22 EXHIBIT A-1 INCUMBENT DISPATCH PROCEDURES [To be Provided] 1. Remedial Maintenance 2. Circuit Provisioning A-23 SCHEDULE B CRITICAL SERVICE LEVELS 1. INTRODUCTION 1.1 General 1.1.1 This Schedule B provides the Critical Service Levels to which Incumbent shall maintain the dedicated DS-1 and DS-3 circuits in order to provide capacity to IXCs and other customers. These Critical Service Levels are derived from and as required by IXCs or other customers for capacity and may be amended from time to time as such requirements may change pursuant to Section 2.3.1 of Schedule C. 1.1.2 The Critical Service Levels are defined by the following parameters: Errored Seconds ("ES"), Severely Errored Seconds ("SES"), and Error Free Seconds ("EFS"). The ES, SES, and the EFS are the only criteria for determining operations above or below Critical Service Levels. 1.1.3 All Systems will be designed for optimum performance based on the equipment manufacturers stated specifications and good system design practices. The Critical Service Levels within this document are subject to change as network design enhancements are implemented and as equipment improvements become available. These Critical Service Levels are based on International Telecommunications Union-Telecommunications ("ITU-T") Services Sector and Bellcore technical specifications. Actual performance data has been analyzed and statistically compared to ITU-T and Bellcore information to arrive at these expected objectives. In the event these specifications are changed, Pathnet shall notify Incumbent and amend such modified Critical Service Levels to this Schedule B. Such revised levels shall be deemed to be changed when Equipment improvements have actually been made at the Facilities. 2. PARAMETER DEFINITIONS 2.1 Certain Definitions The following performance definitions are derived from the DS-1 and DS-3 generic requirements as established by the Industry Standards Compliance list in Section 5: 2.1.1 "Availability" shall mean the time in which the circuit is available and that it is not experiencing an outage. (Usually this term is expressed as percent B-1 availability by taking the ratio of the available time during a given interval to the total interval and multiplying it by 100.) 2.1.2 "Bit Error Rate" ("BER") shall mean the percentage of received bits compared to the total number of bits received. 2.1.3 "Circuit Acceptance Limit" ("AL") shall mean the value used to define the limits at which facilities and/or circuits are placed in service, initially. Upon the acceptance, the facilities and/or circuits are transferred to a performance measuring state to track and insure their continued proper operation. 2.1.4 "Errored Seconds" ("ES") shall mean any one-second interval during which one or more bit errors occurs. (For example, at the DS-1 rate, an ES will contain 1 to 1,544,000 bit errors.) 2.1.5 "Error Free Seconds" ("EFS") shall mean any one-second time interval which does not contain a measurable bit error. (This term may be expressed as a percent EFS by taking the ratio of non-errored to total seconds and multiplying by 100.) 2.1.6 "Failed Seconds" shall mean a one-second interval that has 1,544 bit errors at DS-1 rate. 2.1.7 "In-Service" shall mean the period when IXC service is operating or is revenue bearing. 2.1.8 "Maintenance Limit" ("ML") shall mean the threshold at which the performance of the facility and/or circuit is characterized by degraded performance. 2.1.9 "Outage" shall mean an outage, usually measured in "Outage Seconds", is declared after the BER in each second is worse than 10^-3 for a period of 10 consecutive seconds. These 10 seconds are considered to be unavailable. The unavailable time is counted from when the first of 10 Severely Errored Seconds (SESs) occurs, and ends when the first of 10 consecutive non-SESs occurs second in the sequence. 2.10 "Severely Errored Seconds" ("SES") shall mean (i) at the DS-1 rate, any one-second interval during which the BER is greater than or equal to 1 x 10E^-3. At the DS-1 rate, this equates to 1,544 or more bit errors occurring within one second, and (ii) at the DS-3 rate, any one-second interval during which the BER is equal to or worse than 1 x 10E^-6. B-2 3. DS-1 CRITICAL SERVICE LEVELS 3.1 General Incumbent shall perform the Services in accordance with the Critical Service Levels set forth below. The DS-1 interface shall meet the IXC generic DS-1 requirements that are customary in the industry as set forth in the Industry Standards Compliance List in Section 5 of this Schedule B. 3.2 DS-1 Electrical Interface Specifications Incumbent shall perform the services so that the DS-1 signal at the cross-connect (DSX1) meets each of the following Critical Service Levels: 3.2.1 Line Rate: 1.544 Mb/s. 3.2.2 Tolerance: Source timing for self-timed DS-1 bit streams shall not exceed plus or minus 32 ppm with respect to the basic rate. DS-1 sinks should be capable of accepting a rate deviation of plus or minus 130 ppm. 3.2.3 Line Code: a. Bipolar with at least 12.5 percent average ones density and no more than 15 consecutive zeros. b. Bipolar with Eight Zero Substitution (B8ZS). 3.2.4 Format: ESF with AT&T 54016 & ANSI T1.403 messages, concurrently. 3.2.5 Test Load: A pure resistive termination of 100 ohms plus or minus 5% shall be used for evaluation of pulse shape and electrical parameters. 3.2.6 Pulse Shape: The pulse amplitude shall be between 2.4V and 3.6V measured at the center of the pulse, and may be scaled by a constant factor to fit the template. The source of the above information is ANSI T1.102. 3.2.7 Power Level: a. For Equipment added by Pathnet, for an all-ones transmitted pattern, the power in a band that is no wider than 3 KHz centered at 772 KHz shall be between 12.6 and 17.9 dBm. b. For equipment existing at the sites purchased by Incumbent before the System is modified by Pathnet, the power in a band no wider than 3 KHz centered at 772 KHz shall be between 12.4 and 18.0 dBm. B-3 c. The power in a band no wider than 3 KHz centered at 1544 KHz shall be at least 29 db below that at 772 KHz. 3.3 Jitter Requirements Incumbent shall meet each of the Critical Service Levels at the DS-1 interface for Jitter Tolerance, Jitter Transfer, Jitter Generation, and Jitter Enhancement as set forth in Section 3.3 below. The jitter requirements are set by industry standards as referenced in the Industry Standards Compliance List. 3.3.1 Jitter Tolerance. Jitter Tolerance is the maximum input jitter that any equipment can tolerate without causing errors. It is specified in terms of the amount of sinusoidal jitter (peak-to-peak) versus the frequency of that jitter. IXC generic requirements describe the mask as well as the lower limit of the jitter tolerance at each standard interface level. To meet the jitter tolerance specifications, the actual tolerance of the equipment shall be above the mask and the difference between this and the lower limit represents the safety margin of the equipment. 3.3.2 Jitter Transfer. Jitter Transfer is the jitter gain measurement which is the relationship between the applied input jitter and resulting output jitter as a function of frequency. 3.3.3 Jitter Generation. a. Jitter Generation is defined as the process whereby jitter appears at the output port of an individual unit of digital equipment in the absence of applied input jitter. b. When looped back at the high speed rate, the Equipment shall produce less than 0.3 Unit Interval (UI) of rms timing jitter and less than 1.0 UI of peak-to-peak timing jitter at the output of the terminal receiver. The measurement interval must include all frequencies between F1 and F4 of the Network Jitter Interface requirements, as shown in the Table below. This requirement shall apply over the entire range of permissible input bit-rate offsets. 3.3.4 Jitter Enhancement. The requirement for jitter enhancement is that a system of up to 250 miles in length shall add less than 1.0 UI of peak-to-peak jitter to a DS-3 input signal B-4 having 4.0 UI of sinusoidally modulated peak-to-peak jitter for all frequencies up to 2300 Hz.

INTRODUCTION The Monthly Services Charges and Dispatch Charges, as adjusted by the cost-of-living adjustment ("COLA") set forth in Section 2.2.1, when aggregated with charges for New Services and Pass-Through Expenses as well as other consideration by and between Pathnet and Incumbent provided in the FPM Agreement, shall fully compensate Incumbent for all of the resources used in providing the Services. 2. CHARGES 2.1 Monthly Services Charge Upon Commissioning of each Segment, Pathnet shall pay to Incumbent two hundred fifty hundred dollars ($250) per site per month, payable in equal quarterly installments for providing the Services in accordance With the Performance Standards set forth in Schedule B of this Agreement [LLC consideration to Incumbent for maintenance to be negotiated and derived from LLC receipt of Revenue under the Contingent Radio Revenue Agreement. Such consideration to be entered in this form of agreement] 2.2 Dispatch Charge Pathnet shall pay Incumbent _______ per each Circuit Provisioning dispatch; provided, however Incumbent shall not be compensated for any second dispatch to a site as required by poor Incumbent quality or coordination. (For instance, Field Technician fails to transport required Equipment to perform Circuit Provisioning or a circuit fails to operate in accordance with the Specifications as set forth in Schedule B.) 2.3 Adjustments 2.3.1 Cost of Living Adjustments. a. General. Pathnet agrees to apply a cost of living adjustment ("COLA") to the Monthly Service Charge beginning twenty-four (24) months after the Effective Date. b. Index. The Parties agree to use the Historical Consumer Price Index published as final by the Bureau of Labor Statistics, U.S. Department of Labor for all urban C-1 consumers, U.S. City Average, All Items, Annual Average 1982-84 = 100 ("CPI-U") for purposes of calculating actual inflation. In the event the Bureau of Labor Statistics stops publishing the CPI-U or substantially changes content and format, the Parties will substitute another comparable index published at least annually by a mutually-agreeable source. If the Bureau of Labor Statistics merely redefines the base year for the CPI-U from 1982-84 to another year, the Parties will continue to use the CPI-U, but will convert the protection index to the new base year by using an appropriate conversion formula. c. Calculation of COLA. The COLA will be calculated using the COLA factor specified below. The COLA is payable on a prospective basis (i.e., the Monthly Services Charge by Pathnet for the subsequent renewable contract year will be surcharged by the factor as determined below, if such factor is in excess of zero). The COLA factor will be determined as soon as practicable after the end of each contract year, starting with the third renewable contract year. The COLA factor is: Actual Inflation x COLA Percentage, where Actual Inflation = CPI-U for the calendar year just ended. COLA Percentage = seventy-five (75%) percent. 2.4 Additional Charges 2.4.1 New Services. In the event that Pathnet requests Incumbent to perform functions that are materially different from and in addition to the Services ("New Services"), the Parties' obligations with respect to such functions shall be as follows: a. To the extent that such functions may be performed with existing resources and existing allocation of personnel time under this Maintenance Agreement, the additional functions shall then be considered "Services" and shall be subject to the provisions of this Agreement. b. To the extent that such functions require additional resources or may not be performed with the existing allocation of personnel time under this Agreement, then prior to performing such additional functions. Incumbent shall quote to Pathnet: (i) a charge for such additional functions that is reasonable within the industry. C-2 (ii) the reasonable number of hours to perform such additional functions and such additional functions shall be performed at the rates set forth in Exhibit C-1 to this Schedule C. (iii) in the case of Maintenance requested for an interconnection site, the additional charge shall be fifty (50%) percent of the current Monthly Service Charge for such site. c. Pathnet, upon receipt of such quote, may elect to have Incumbent perform the additional functions and the charges under this Agreement shall be adjusted if appropriate to reflect such functions. If Pathnet so elects, such service shall then be deemed "Services" and shall be subject to the provision of this Maintenance Agreement. a. Pathnet may elect to solicit and receive bids from third parties to perform such additional functions. If Pathnet elects to contract for such third-party services, Incumbent shall cooperate with those third parties with respect to the provision of such service. b. The Parties anticipate that the Services will evolve and be supplemented, modified, enhanced or replaced over time to keep pace with technological advancements and improvements in the methods of delivering services, and the Parties acknowledge that these will not be deemed to result in functions materially different from and in addition to the Services. c. If Pathnet's request for additional functions, pursuant to this Section 3.1.1, includes a request for Incumbent to correspondingly reduce or eliminate Services it is providing, then such additional functions will be considered "Replacement Service". In such event, the Parties shall determine the resources and expenses required to provide the Replacement Services, including implementation and ongoing support, and the reduction in resources and expenses related to the Services being replaced. The net increase or decrease in resources and expenses will be the basis on which Incumbent shall quote a price for Replacement Services pursuant to subsection (b). 2.4.2 Pass-Through Expenses. Pass-Through Expenses are charges to be paid directly by Pathnet, unless the Parties mutually agree that particular Pass-Through Expenses are to be paid by Incumbent, followed by reimbursement from Pathnet. Pass-Through Expenses in excess of five hundred ($500) dollars may not be added to the Monthly Services C-3 Charge without Pathnet's prior written consent, which Pathnet may withhold in its sole discretion. Pass-Through Expenses shall be calculated as Incumbent's reasonable out-of-pocket expenses (as incurred and paid for by Incumbent). Incumbent shall promptly provide Pathnet with the original third-party invoice for such expenses, together with a statement that Incumbent has reviewed the invoiced charges and made a determination of which charges are proper and valid and shall be paid by Pathnet. Pass-Through Expenses shall continue to be booked to the Pathnet office. It shall be Incumbent's responsibility to manage the invoicing of Pass-Through Expenses to Pathnet such that late charges are not incurred.
