(the Communications Act), by and between PUERTO RICO TELEPHONE COMPANY, INC. (PRT or PRTC), a
corporation organized and existing under the laws of the Commonwealth of Puerto Rico, and CORTELCO SYSTEMS PUERTO RICO, INC.
(CSPR) a corporation organized under the laws of the Commonwealth of Puerto Rico (each a Party and together

Agreement by the Telecommunications Regulatory Board of Puerto Rico (Board) under the terms of Section 252 of the
Communications Act.

WHEREAS, the Parties have agreed, among other things, to interconnect their local exchange networks for the transmission and termination of calls so that Customers of each Party may receive calls that originate on the other Party's network and place calls that terminate on the other Party's network; and

WHEREAS, the Parties intend the rates, terms and conditions of this Agreement, and the performance of their obligations hereunder, to comply with the Communications Act of 1934, as amended, the orders and rules of the Federal Communications Commission ("FCC"), the Puerto Rico Telecommunications Communications Act of 1996 (Puerto Rico Act), and the orders and rules of the Board;

NOW, THEREFORE, in consideration of the terms and conditions contained herein, CSPR and PRT hereby mutually agree as follows:

1.

In the event of any textual ambiguity as to the intentions of the Parties regarding any term of this Agreement and a dispute between the Parties regarding the proper resolution of such textual ambiguity, the textual ambiguity shall be resolved in a manner that is consistent with the requirements of the Communications Act and the Puerto Rico Act and that limits the subject rights and obligations of the Parties to those clearly established thereby.

2.

Term of Agreement

2.1

The term of this Agreement shall begin on the Effective Date and, unless the Agreement is cancelled or terminated earlier or the term is extended, all in accordance with the provisions hereof, shall end at 11:59am Atlantic Time on the date that is three (3) years after the Effective Date.

2.2

By agreement set forth in writing as provided in Section 41 hereof, the Parties may extend the term of this Agreement.



3.

Territory

3.1

This Agreement applies to the territory in which PRT operates as an Incumbent Local Exchange Carrier in the Commonwealth of Puerto Rico (Operating Territory). PRT shall be obligated to provide a Service under this Agreement only within this territory.

3.2

If PRT sells or otherwise transfers its operations or assets in such Operating Territory or portion thereof to a Person or entity that is not an Affiliate of PRT, PRT shall assign this Agreement to the Person or entity purchasing or acquiring PRT’s operations or assets in such Operating Territory of the affected portion thereof. This Section 3.2 shall not be construed as a waiver by CSPR of any right to challenge or to seek the imposition and/or enforcement of conditions on any PRT sale or transfer of its operations or assets in its Operating Territory or any portion thereof.



4.

Regulatory Approval and Legal, Regulatory, or Judicial Changes

4.1

This Agreement and any amendment hereto, will be submitted to the Board for approval in accordance with Section 252 of the Communications Act and Chapter III, Article 5 of the Puerto Rico Act. PRT and CSPR shall use their best efforts to obtain approval of this Agreement, and any amendment hereto, by the Board.

4.2

In the event that the Board rejects any provision of this Agreement, the Parties shall negotiate promptly and in good faith revisions as may reasonably be required to achieve approval of the Agreement.

4.3

In the event that, following Board approval of this Agreement, a court of competent jurisdiction (on appeal from the Board’s approval) finds that any of the terms of this Agreement are inconsistent in one or more material respects with Applicable Law, then, once such decision is final and no longer subject to administrative or judicial review, the Parties immediately shall commence good faith negotiations to conform this Agreement to the terms of such decision or to the terms of the subject Applicable Law (Appeal Change). Unless established otherwise by the Board or the reviewing court, the Parties will make an Appeal Change by written amendment submitted to the Board for approval within thirty (30) days after the date that the finding requiring such modification becomes



General Terms and Conditions  Page 2

final (Amendment Due Date). If agreement is not reached on the amendment by the Amendment Due Date, the Parties will submit their respective proposals for the amendment on the Amendment Due Date (provided it falls on a Business Day, and on the next Business Day thereafter if it does not) with a joint request for the Board to establish and approve an appropriate amendment. Unless established otherwise by the Board or the reviewing court, the effective date of the Appeal Change amendment shall be the same as the Effective Date of this Agreement, with the terms of such amendment applied retroactively to the Effective Date. Neither Party shall seek a result from the Board or reviewing court that is inconsistent with the terms of the preceding sentence. In the event that such retroactive application requires a true-up of amounts due and/or paid between the Parties pursuant to this Agreement,
the Parties agree to work together in good faith to determine the amount of such true-up and agree further to effectuate the true-up of undisputed amounts within no more than sixty (60) days after the date of the Board’s approval of the Appeal Change amendment.

4.4

In the event that any Applicable Law becomes effective or is changed following the Effective Date and materially affects any term(s) of this Agreement (hereinafter referred to as Change in Law), either Party may, in writing, request to negotiate with the other Party whether and how such term(s) shall be modified to address the Change in Law. The Parties are duty bound to negotiate regarding any such Change in Law modification(s) in good faith, and the Parties shall complete their negotiations within thirty (30) days after the date on which the written request for negotiation is received by the non-requesting Party. If the Parties do not agree on such Change in Law modification(s) within that thirty day negotiation period, then, after the end of the thirty (30) day period set forth in Section 29.2, calculated from the beginning of the thirty-day period described in the preceding sentence, the provisions of Section 29.2 of this Agreement
shall apply; provided, however, that the Parties shall continue to work in good faith toward the resolution of the disagreement regardless of whether the provisions of Section 29.2 are invoked to address the matter or not. The Parties shall promptly (but in any event within fifteen (15) days after the date on which the Parties agree on such Change in Law amendment or receive a resolution of a Change in Law disagreement under Section 29.2 whichever is earlier) submit an agreed upon Change in Law amendment to this Agreement to the Board for approval. Subject to the provisions of Section 4.1 above, the Change in Law Amendment Agreement shall have an effective date that coincides with the effective date of the Change in Law giving rise to such negotiations. Neither Party shall seek a result from the Board or a court that is inconsistent with the terms of the preceding sentence. The Parties agree that, except as otherwise provided herein, the rates, terms, and conditions of any Change in Law Amendment shall not
be applied retroactively to any period prior to such effective date. Except in the event of a Change in Law as defined in this subsection neither party may seek to renegotiate the terms of this Agreement. Moreover neither party may request to negotiate the terms of a successor to, or renewal of, this Agreement, or any agreement having substantially similar terms, prior to one year before the expiration date of this Agreement.

4.5

Notwithstanding anything in this Agreement to the contrary, if, as a result of any Change in Law, PRT is not required by Applicable Law to provide any Service, payment or benefit, otherwise required to be provided to CSPR hereunder, then,



General Terms and Conditions  Page 3



---

subject to the provisions of Section 32 and subject to an effective amendment to this Agreement pursuant to the terms of Section 4.4 implementing such Change in Law, PRT may discontinue the provision of any such Service, payment or benefit, and CSPR shall reimburse PRT for any payment previously made by PRT to CSPR that was not required by Applicable Law.

5.

Reservation of Rights

Notwithstanding anything to the contrary in this Agreement, neither Party waives, and each Party hereby expressly reserves, its rights: (a) to seek reconsideration of, to appeal, or otherwise to pursue the reversal of and changes in any arbitration decision associated with this Agreement; (b) to seek changes in this Agreement (including, but not limited to, changes in rates, charges, and the Services that must be offered) through changes in Applicable Law; (c) to challenge the lawfulness and propriety of, and to seek to change, any Applicable Law, including, but not limited to any rule, regulation, order or decision of the Board, the FCC, or a court of applicable jurisdiction; and (d) to collect debts owed to it under any prior interconnection or resale agreements. Nothing in this Agreement shall be deemed to limit or prejudice any position a Party has taken or may take before the Board, the FCC, any




other Commonwealth or federal regulatory or legislative bodies, courts of applicable jurisdiction, or industry forum. The provisions of this Section shall survive the expiration, cancellation or termination of this Agreement.

6.

Predecessor Agreements; Transition Provisions

6.1

Notwithstanding any other provision of this Agreement or otherwise, all monetary obligations of the Parties to one another incurred under that certain Interconnection Agreement by and between CSPR and Puerto Rico Telephone Company, Inc., which was executed by the parties thereto as of November 12, 2004 and was approved by the Board on November 23, 2004 (2004 Interconnection Agreement), shall remain in full force and effect under this Agreement; provided, however, that the terms of the 2004 Interconnection Agreement that governed the rights and obligations of the Parties with respect to billing, paying, and disputing amounts incurred under the 2004 Interconnection Agreement shall continue to govern with respect to such amounts, but only such amounts, under this Agreement.

6.2

Notwithstanding the foregoing, nothing contained in this Agreement shall convert any claim or debt that would otherwise constitute a prepetition claim or debt in a bankruptcy case into a postpetition claim or debt. Each Party expressly reserves all of its rights under the Bankruptcy Code and Applicable Law to seek or oppose any relief in respect of the assumption, assumption and assignment, or rejection of any interconnection, resale, or unbundling arrangements between PRT and CSPR.

6.3.2

Except as otherwise provided in Sections 6.3.3 or 6.3.4, a CSPR order for Service submitted to PRT prior to the Effective Date and in accordance with the terms of the 2004 Interconnection Agreement, but still pending with PRT on the Effective Date (hereinafter referred to as a Transitioned Order), shall be processed and completed without interruption or delay in accordance with the terms of the 2004 Interconnection Agreement. For the purposes of the prior sentence, an order for Service is still pending if PRT has not yet delivered an order completion notice under the terms of Section 7.2.3.5 of the Additional Services Attachment to the 2004 Interconnection Agreement with respect to the subject order and the subject order has not been rejected or suspended under the terms of Section 7.2.3.5 of the Additional Services Attachment to the 2004 Interconnection Agreement.

recurring and usage charges for Services established in accordance with Transitioned Orders shall be the applicable monthly recurring charges set forth in this Agreement; and

6.3.3.6

recurring and usage charges for Services established in accordance with CSPR service orders received by PRT on or

General Terms and Conditions  Page 5



---

after the Effective Date shall be the applicable monthly recurring charges set forth in this Agreement.

6.3.4

If a 2004 Service is not available pursuant to this Agreement (hereinafter referred to as a Terminated Service), the provisions of this Section 6.3.4 shall govern the treatment of any such service following the Effective Date.

6.3.4.1

Not later than the date that is fifteen (15) days after the Effective Date, PRT and CSPR shall establish a transition committee comprised of four individuals, two of whom shall be appointed by PRT and two of who shall be appointed by CSPR (hereinafter the Transition Committee). Each member of the Transition Committee shall serve at the pleasure of the Party that appointed the individual.

6.3.4.2

Not later than the date that is thirty (30) days after the Effective Date, each Party shall deliver to the other Party a list of:

6.3.4.2.1

any all CSPR lines as to which a Terminated Service is being provided by PRT (each, a Terminated Service Line); and

6.3.4.2.2

any and all CSPR orders for any Terminated Service that have been submitted to PRT but which remain pending (each, a Terminated Service Order).

6.3.4.3

Within the period ending ten days after the date on which
each Party has received the list from the other Party as contemplated in Section 6.3.4.2, the Transition
Committee shall attempt to resolve, in good faith, any discrepancies between the lists so delivered. Within the
ten day period set forth in the preceding sentence, the Transition Committee shall create a unitary list of any
and all Terminated Service Lines and Terminated Service Orders regarding which the Parties agree (hereinafter
referred to as the Transition Committee List) and shall deliver such Transition Committee List to the Parties.
Any discrepancies in the lists exchanged pursuant to Section 6.3.4.2 that cannot be resolved in good faith by the
Transition Committee shall be resolved in accordance with the dispute resolution procedures set forth in Section
29.2 of this Agreement without applying the negotiation period obligation called for under Section 29.1.
For the duration of any such dispute proceeding, but not to exceed the period ending ninety (90) days after the Effective Date, the subject Terminated Service Line(s)
or Terminated Service Order(s) shall continue to be offered and/or provisioned without delay or interruption in accordance with and subject to the terms of the 2004
Interconnection Agreement.

order the disconnection of the Terminated Service to the Terminated Service Line without other action; or

PRTC shall complete the implementation of each CSPR order received under Section 6.3.4.4. Until the CSPR order received under Section 6.3.4.4 is implemented by PRTC as to a particular Terminated Service Line, the Terminated Service shall continue to be provided by PRT to CSPR with respect to that Terminated Service Line pursuant to the terms that the Terminated Service was provided under the 2004 Interconnection Agreement. Each CSPR order for a new Service submitted pursuant to Section 6.3.4.4.3 shall be processed by PRT under the applicable terms of this Agreement.

With respect to each Terminated Service Order that appears on the Transition Committee List, not later than the date that is ten days after the Transition Committee List is delivered to the Parties, CSPR in writing shall:

8.3

If the Providing Party does not collect any Tax as required by Section 16.1 because the Purchasing Party has provided such Providing Party with an exemption certificate that is later found to be inadequate by a taxing authority, then, as between the Providing Party and the Purchasing Party, the Purchasing Party shall be liable for such uncollected Tax and any interest assessed thereon, as well as any penalty assessed
with respect to such uncollected Tax by the applicable taxing authority.

If Applicable Law clearly exempts a purchase hereunder from a Tax, but does not also provide an exemption procedure, then the Providing Party shall not collect such Tax if the Purchasing Party (a) furnishes the Providing Party with a letter signed by an officer requesting such an exemption and citing the provision in the Applicable Law which clearly allows such exemption and (b) supplies the Providing Party with an indemnification

Where CSPR has made assurance of payment under Section 18.3 and subsequently demonstrates good payment history by paying undisputed amounts by the Payment Due Date applicable thereto for six (6) consecutive months, then, beginning in the seventh month, CSPR shall be released from its obligations under Section 18.3 with regard to the assurance of payment so given and may request the return or release of the assurance of payment so given, which, in turn, shall be returned or released by PRT. Thereafter, CSPR will remain subject to the requirements of this Section 18 in the event that, subsequent to its release under this section, CSPR again satisfies any of the conditions providing PRT with the right to demand an assurance of payment under section 18.3.

18.9

If, before PRT has exercised the right to require and/or draw on an assurance of payment in accordance with this section, CSPR has paid in full the amount outstanding giving rise to PRT’s exercise of such right pursuant to this Section 18, PRT shall no longer be entitled to the exercise of such right based upon such previously outstanding amount.

Audits

19.1

Either Party (the Auditing Party) may audit the other Partys (the Audited Party) books, call detail records, data, reports, and other records, documents, and materials for the purposes of determining the traffic type and volume of traffic exchanged by the Parties over facilities provided for in this Agreement, the other Party’s compliance with obligations set forth in this Agreement, and/or may audit to verify accuracy of the Audited party or Auditing Partys invoices. To institute an Audit under this Section 19, the Auditing Party shall notify the Audited Party in writing of the Audit, specifying the period of the Audit computed in accordance with Section 19.2.

19.2

The period of the Audit shall be the shorter of (i) the period beginning the first day following the last day of the period covered by the Audit which was last performed (or if no Audit has been performed, the Effective Date of this Agreement) and ending on the date on which the Audited Party received written notice of the Audit at issue under Section 19.1, and (ii) the twelve (12) month period ending on the date on which the Audited Party received written notice of the Audit at issue under Section 19.1, but in any event not prior to the Effective Date of this Agreement. Such Audit shall begin no later than thirty (30) days after the Audited Party received written notice of the Audit under Section 19.1.

19.3

Such Audit shall be conducted by (a) an independent auditor selected by the Auditing Party, subject to the approval of the Audited Party, which approval shall not be unreasonably withheld or delayed, or (b) if the Parties so agree in writing, by an employee or employees of the Auditing Party (in either case, the Auditor(s)). The Auditing Party shall cause the Auditor(s) to execute a nondisclosure agreement, in a form agreed upon by the Parties, regarding the treatment of Confidential Information disclosed or developed in the course of the Audit.

19.4

Each Audit shall be conducted on the premises of the Audited Party during normal business hours. The Audited Party shall cooperate fully in the conduct of any such Audit and shall provide the Auditor(s) reasonable access to any and all Audited Party employees and any and all books, call detail records, data, reports, and other records, documents, and materials, whether maintained in writing, electronically, or otherwise, and whether or not stored on the premises of the Audited Party, including, but not limited to, any data or information contained in any computer or other memory system, that, in the judgment of the Auditor(s), are probative of the matter or matters under examination in the Audit. If the Audited Party fails to adhere materially to the requirements of this Section 19.4 and such failure is not materially corrected within three (3) Business Days after receiving written notice thereof from the Auditing Party, the Audited Party shall be
responsible for all of the auditors total fees and expenses for the Audit.

19.5

Each Party shall maintain books, call detail records, data, reports, and other records, documents, and materials that are relevant to the matters set forth in Section 19.1 for a period of not less than twenty-seven (27) months after creation thereof, unless a longer period is required by Applicable Law.

General Terms and Conditions  Page 35

19.6

The results of a Audit conducted under this Section 19 shall be furnished to the Audited Party in writing. The date on which the Audited Party receives the results of the Audit under this Section shall be the Audit Result Notice Date.

19.7

Subject to the terms of Section 19.8 below, should the results of such Audit show that (i) the Audited Party has delivered or knowingly or negligently caused to be received on a particular trunk a traffic type other than that identified for the other Party for the relevant period under the terms of the Interconnection Attachment to this Agreement, (ii) the volume of traffic, the type of traffic, and/or the volume of a particular type of traffic delivered or received on a particular trunk was different than that previously invoiced by or to the Auditing Party by or to the Audited Party, (iii) the Audited Party is in breach of this Agreement, and/or (iv) any invoice or invoices delivered by or to the Audited Party by or to the Auditing Party under this Agreement was or were inaccurate (jointly referred to hereinafter as an Audited Party Correction Result), then (x) immediately, but not later than thirty (30) days after the Audit Result
Notice Date, the Audited Party shall correct the breach, and, if appropriate, the Auditing Party may, deliver to the other Party a replacement invoice to conform any and all invoices previously delivered to that other Party for the period of the Audit to the results of the Audit; provided, however, that the failure of either Party to deliver a replacement invoice under this clause, or to deliver a replacement invoice that satisfies the requirements of this clause, shall not relieve the Audited Party of its obligation to adhere to the results of the Audit and to comply with the requirements of this Section, except as provided in Section 19.8 below; and (y) not later than forty-five (45) days after the Audit Result Notice Date, the Parties shall make such interParty payments as are necessary to conform amounts previously paid by one Party to the other to the amounts due under the results of the Audit.

19.8

Notwithstanding the provisions of Section 19.7, if the Audited Party reasonably disputes the results of the Audit furnished under Section 19.6, the Audited Party shall so notify the Auditing Party in writing not later than thirty (30) days after the Audit Result Notice Date and the dispute shall be referred to the Parties’ respective personnel responsible for informal dispute resolution. If these individuals do not resolve the referred dispute within the period ending sixty (60) days after the Audit Result Notice Date, then, the provisions of Section 29 of this Agreement shall apply; provided, however, that the Parties shall continue to work in good faith toward the resolution of the disagreement regardless of whether the provisions of Section 29 are invoked to address the matter or not.

19.9

The failure of the Audited Party to dispute the results of an Audit as provided under the terms of Section 19.8 shall constitute the Audited Partys acceptance of the results of the Audit furnished under Section 19.6 and its agreement to be bound thereby.

19.10

Except as may be otherwise provided in this Section 19, an Audit shall be conducted at the Auditing Partys expense, subject to reimbursement by the Audited Party as provided in this Section 19.10 in the event that the results of the Audit show an Audited Party Correction Result. The amount to be reimbursed by the Audited Party under this Section 19.10 shall be the lesser of (i) an amount equal to one-half (1/2) of the auditor’s total fees and expenses or (ii) an amount equal to the net amount owed by the Audited Party to the Auditing Party under the results of the Audit.

General Terms and Conditions  Page 36

19.11

Any inaccuracies or system processes resulting in such inaccuracies uncovered by an Audit must be corrected by the Parties so that such inaccuracies do not recur. Each Party shall make any and all such corrections within ninety (90) days of the conclusion of the Audit or, if not reasonable within such period, within a timeframe mutually agreed to by the Parties, with such timeframe not to exceed six (6) months from the conclusion of the Audit. Within such timeframe, the Audited Party shall also provide to the Auditing Party a written description of the measures taken by the Auditing Party to correct such inaccuracies and provide notification of when such corrections will be effective.



20.

Revenue Protection

The Parties shall cooperate fully with one another to investigate, minimize, and take corrective action in cases of fraud; provided, however, that nothing in this Section 20 shall change the responsibility for any fraud-related loss that would arise in the absence of this provision.

21.

Good Faith Performance

The Parties shall act in good faith in their performance of this Agreement, including, but not limited to, having the necessary systems and processes in place to perform as required as of the Effective Date of the Agreement and avoiding repeated breaches of obligations set forth in this Agreement. Except as otherwise expressly stated in this Agreement (including, but not limited to, where consent, approval, agreement or a similar action is stated to be within a Partys sole discretion), where consent, approval, mutual agreement or a similar action is required by any provision of this Agreement, such action shall not be unreasonably withheld, conditioned or delayed.

22.2

A Party shall not have the obligation to inform the other Party or the Customers of the other Party of actions taken in cooperating with law enforcement or national security authorities, except to the extent required by Applicable Law.

22.3

Where a law enforcement or national security request relates to the establishment of lines (including, but not limited to, lines established to support interception of communications on other lines), or the installation of other services, facilities or arrangements, a Party may, to the extent required by Applicable Law, act to prevent the other Party from obtaining access to information concerning such lines, services, facilities and arrangements, through operations support system interfaces.

23.

Parity of Service

Except as otherwise provided herein, PRT shall perform its obligations and duties under this Agreement, and will provide Services and network functions, including but not limited to local interconnection, with a quality of service and a level of performance at parity with that which it uses for its own operations or the operations of its Affiliates or for the provision of services to its own Customers or the Customers of its Affiliates.

24.

25.

Network Management

25.1

The Parties will work cooperatively in a commercially reasonable manner to install and maintain a reliable network. CSPR and PRT will exchange appropriate information (e.g., network information, maintenance contact numbers, escalation procedures, and information required to comply with requirements of law enforcement and national security agencies) to achieve this desired reliability. In addition, the Parties will work cooperatively in a commercially reasonable manner to apply sound network management principles to alleviate or to prevent traffic congestion and subject to Section 20, to minimize fraud associated with third number billed calls, calling card calls, and other Services related to this Agreement.

25.2

Each Party recognizes a responsibility to follow the standards that may be agreed to between the Parties and to employ characteristics and methods of operation that will not interfere with or impair the service, network or facilities of the other Party or any Third Parties connected with or involved directly in the network or facilities of the other.

25.3

If a Party (Impaired Party) reasonably determines that the services, network, facilities, or methods of operation, of the other Party (Interfering Party) will or are likely to interfere with or impair the Impaired Partys provision of services or the operation of the Impaired Partys network or facilities, the Impaired Party may interrupt or suspend any Service provided to the Interfering Party to the extent necessary to prevent such interference or impairment, subject to the following:

25.3.1

Except in emergency situations (e.g., situations involving a risk of bodily injury to Persons or damage to tangible property, or an interruption in Customer service) or as otherwise provided in this Agreement, the Impaired Party shall have given the Interfering Party at least ten (10) days prior written notice of the interference or impairment or potential interference or impairment and the need to correct the condition within said time period; and taken other actions, if any, required by Applicable Law; and,

25.3.2

Upon correction of the interference or impairment, the Impaired Party will promptly restore the interrupted or suspended Service. The Impaired Party shall not be obligated to provide an out-of-service credit allowance or other compensation to the Interfering Party in connection with the suspended Service.

25.4

In the event of an outage or trouble in any Service being provided by a Party hereunder, the Providing Party will follow the other Partys standard procedures

General Terms and Conditions  Page 38

for isolating and clearing the outage or trouble, provided, however, that such standard procedures are nondiscriminatory and have been provided to the other Party in writing on or prior to the Effective Date, if then existing, but, in any event, prior to the relevant outage or trouble.

26.

Designation of Points of Contact

26.1

To facilitate coordination by and between the Parties regarding the exercise of their respective rights and the performance of their respective obligations under this Agreement, each Party shall, upon the written request of the other Party made under the terms of Section 40 of these General Terms and Conditions, designate in writing a point(s) of contact(s) for a particular identified right or obligation. The designation of such an individual(s) shall be made and delivered to the requesting Party under the terms of Section 40 of these General Terms and Conditions no more than five (5) Business Days after the date the written request is received by the designating Party, and the Person or Persons so designated shall have substantive familiarity with the subject matter of the identified right or obligation, provided, however, that the designation of an individual under the terms of this Section 26.1 shall not constitute, nor shall it be construed as,




an acknowledgement or assumption by the designating Party of any right or obligation under this Agreement or otherwise, and the designating Party shall retain full discretion to dispute the existence of all or any part of a right or obligation asserted by the other Party. The point of contact shall be responsible for coordinating the designating Partys performance, if any, with respect to the identified right or obligation, subject at all times to the provisions of this Agreement. The written designation delivered to the requesting Party shall include the single point of contact’s immediate supervisor, the supervisors immediate supervisor, and telephone and electronic mail contact information for each designated point of contact and identified supervisor.

26.2

When a Party receives a communication from a Customer of the other Party, it shall give the Customer a telephone number at which he or she may contact the other Party directly. The telephone number for PRT to provide to CSPR Customers is 800-226-4884. The telephone number for CSPR to provide to PRT Customers is 611.

Choice of Law

The construction, interpretation, and performance of this Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Puerto Rico, except for its conflicts of law provisions.

29.

Dispute Resolution

29.1

Except as otherwise provided in this Agreement, any dispute between the Parties, regarding the interpretation or enforcement of this Agreement or any

General Terms and Conditions  Page 39



---

of its terms shall be addressed by good faith negotiation between the Parties. To initiate such negotiation, a Party must provide to the other Party written notice of the dispute that includes both a detailed description of the dispute or alleged nonperformance and the name of an individual who will serve as the initiating Partys representative in the negotiation. Within five (5) Business Days of receiving the request for negotiation, the other Party shall, in a written notice delivered to the requesting Party, designate its own representative in the negotiation. The Parties’ representatives shall meet at least once within thirty (30) days after the date of the initiating Party’s written notice in an attempt to reach a good faith resolution of the dispute. Upon agreement, the Parties representatives may utilize other alternative
dispute resolution procedures such as private mediation to assist in the negotiations.

29.2

If the Parties have been unable to resolve the dispute, or a Party fails to make itself available to meet as required under Section 29.1, within thirty (30) days of the date of the initiating Partys written notice, either Party may pursue any remedies available to it under this Agreement, at law, in equity, or otherwise, including, but not limited to, instituting an appropriate proceeding before the Board, the FCC, or a court of competent jurisdiction or EDR as set forth below.

29.2.1

In the event that the Parties institute proceedings in different forums to resolve the same dispute under Section 29.2, the dispute shall be resolved in the forum selected by the Party that provided the notice initiating negotiation of the dispute as set forth in Section 29.1 provided that such Party (a) shall have instituted a proceeding in the forum it selected not later than twenty-one (21) days after the date on which a proceeding to resolve the same dispute was instituted in a competing forum by the other Party and (b) shall have not already consented to the jurisdiction of the forum selected by the other Party. Upon determining the proper forum for a dispute in accordance with this Section 29.2.1, the Party that instituted a proceeding in the other forum to resolve the same dispute shall withdraw its complaint with such forum and/or take such other action necessary to terminate such proceeding.

29.3

The minimum negotiation period provided for in Section 29.2 shall not apply where immediate and/or emergency equitable relief is reasonably warranted under the circumstances, including, but not limited to, disputes involving the possible discontinuation of service to end user Customers.

29.4

Expedited Dispute Resolution (EDR). EDR shall be available as a damage recovery, dispute resolution, and enforcement mechanism for matters arising under this Agreement.

29.4.1

In EDR, either Party may have a dispute arbitrated by the American Arbitration Association (AAA) pursuant to its then-prevailing Commercial Arbitration Rules.

29.4.2

The Parties agree that the arbitration will be binding and be conducted in San Juan, Puerto Rico, unless otherwise agreed by the Parties.

29.4.3

The Parties will select a mutually agreeable arbitrator (who may be from outside Puerto Rico). The Parties will agree on an arbitrator within ten

General Terms and Conditions  Page 40



---

(10) days after one party notifies the other of its desire to seek arbitration. If the Parties do not agree on an arbitrator within ten (10) days as set forth in the preceding sentence, either Party may request that an arbitrator be designated by AAA, with such designation to be made within twenty (20) days of such request.

29.4.4

The arbitrator shall establish a schedule to resolve the issues between the Parties within sixty (60) days of the date of the arbitrator’s designation and the Parties shall ask the arbitrator to complete the resolution of the issues in dispute within that period.

29.4.5

If the matter brought to EDR concerns factual issues, discovery may be made available at the direction of the arbitrator, subject to the desire of the Parties to conclude the arbitration in an efficient and expeditious manner. In the event that discovery is required, the arbitrator shall be empowered to resolve all discovery disputes and, where necessary, to compel production of documents, answers to interrogatories, and other necessary relief.

29.4.6

For a matter brought to EDR, the arbitrator may, as requested by a Party, award damages, legal costs, and that one Party pay the other Party’s share of the costs of the EDR as and to the extent consistent with the standards set forth in Rule 44 of the Puerto Rico Rules of Civil Procedure and jurisprudence related thereto.

29.4.7

To the extent that there is a dispute between the Parties over whether EDR is available under this Agreement with regard to any claim for which a Party seeks EDR, such dispute shall be subject to EDR under this Agreement and may be resolved by the arbitrator in the same EDR proceeding that is being contested.

29.4.8

Only counterclaims that would be considered to be compulsory counterclaims under Rule 13(a) of the Federal Rules of Civil Procedure and related jurisprudence shall be permitted in EDR; provided, however, that this limitation shall not constitute a waiver of any non-permitted claim nor preclude the prosecution of any such claim in a separate EDR or other proceeding.

29.4.9

Subject to Section 29.4.6 of this Attachment, the Parties shall split the cost of an EDR equally. For the purposes of this Section 29.4.9, the costs of an EDR do not include each Partys respective legal costs associated with the retention and use of counsel in the EDR.

29.4.10

The Parties agree that the timeframes set forth for EDR are a material aspect of the EDR process and that the arbitrator and the Parties shall take all reasonable steps to ensure that such timeframes are met.

29.5

In the event that a Party is adjudged through a dispute resolution proceeding prosecuted in accordance with Section 29 to have violated any requirement of Applicable Law as reflected or imposed in this Agreement or this Agreement, such Party shall be responsible to pay all reasonable legal costs incurred by the other Party in prosecuting such proceeding as and to the extent consistent with

Remedies

Except as otherwise provided in this Agreement, and subject to the provisions of Section 17, all rights of withholding payment, termination, cancellation, or remedies prescribed in this Agreement, or otherwise available, are cumulative and are not intended to be exclusive of remedies to which the injured Party may be entitled at law or equity in case of any breach or threatened breach by the other Party of any provision of this Agreement, and use of one or more remedies shall not bar use of any remedy for the purpose of enforcing the provisions of this Agreement.

the non-defaulting Party provides written notice of the Default under the terms of Section 40, which written notice shall reasonably set forth the nature of the Default and shall indicate a specific term or condition of this Agreement that constitutes the grounds for the Default; and

31.2.2

the defaulting Party does not, within thirty (30) days after receiving written notice of the Default under Section 31.2.1, either (i) remedy the Default or (ii) initiate proceedings provided for in Section 29 without regard to the thirty-day negotiation period set forth for therein.

31.3

such discontinuance is authorized under the provisions of this Agreement, including, without limitation, the provisions of Sections 4 and 31 of these General Terms and Conditions; and

PRT shall not discontinue any Service provided or available under this Agreement without providing CSPR prior written notice of such discontinuation as soon as reasonably possible after it is determined that such Service will be discontinued and, in any event, not less than ninety (90) days prior to the implementation of such discontinuation; provided, however, that, in the case of Default, such notice shall not be given without first proceeding under the terms of Section 31 of this Agreement.

33.

Discontinuance of Service by CSPR

33.1

If CSPR proposes to discontinue, or actually discontinues, its provision of service to all or substantially all of its Customer, whether voluntarily, as a result of bankruptcy, or for any other reason, CSPR shall send written notice of such discontinuance to PRT, the Board, and each such CSPR Customer. CSPR shall provide such notice such number of days in advance of discontinuance of its service as shall be required by Applicable Law. Unless the period for advance notice of discontinuance of service required by Applicable Law is more than thirty (30) days, to the extent commercially feasible, CSPR shall send such notice at least thirty (30) days prior to its discontinuance of service.

33.2

Intentionally Omitted

35.

No Waiver

35.1

The failure or delay of either Party to enforce any term of this Agreement, to exercise any right that is herein provided, or to require the performance of any provision hereof shall in no way be construed to be a waiver of such term, right, or provision; provided, however, that this Section 35.1 shall not be construed to interfere with any provision of this Agreement that expressly and specifically provides for such waiver.
