 Exhibit 10.10 
 PLAN SUPPORT AGREEMENT 
 This PLAN SUPPORT AGREEMENT is made and entered into as of March 16,
2009 (as may be amended from time to time in accordance with the terms set forth herein, this “Agreement”) by and among the following parties: 
 (a) The undersigned beneficial owners of, or holders of investment authority over (subject to the
addendum attached hereto) (each, a “Consenting Noteholder,” and collectively, the “Consenting Noteholders”), the (i) 8% Senior Notes due 2014 (the “8% Notes”) issued by Primus
Telecommunications Holding, Inc. (“Holding”) and guaranteed by Primus Telecommunications Group, Incorporated (“Group”), (ii) 5% Exchangeable Senior Notes due 2010 (the “5% Notes,” and together
with the 8% Notes, the “Holding Notes”) issued by Holding and guaranteed by Group, and/or (iii) 14  1/4% Senior Secured Notes due 2011 (the “IHC Second Lien Notes”) issued by Primus Telecommunications IHC, Inc. (“IHC”) and guaranteed by Group, Holding and certain other subsidiaries of Group (the Holding
Notes and the IHC Second Lien Notes referred to in clauses (i), (ii) and (iii) collectively referred to as the “Notes”); and 
 (b) Group, Holding, IHC and Primus Telecommunications International, Inc. (“PTII”) (Group, Holding, IHC and PTII collectively, the “Debtors”) (the Debtors, each of the foregoing Consenting
Noteholders and any subsequent person that becomes a party hereto as a Consenting Noteholder (pursuant to the Joinder attached hereto as Exhibit B), a “Party,” and collectively, the “Parties”). 
 RECITALS 
 WHEREAS, each
Consenting Noteholder is the beneficial holder of a Claim, as that term is defined in section 101(5) of title 11 of the United States Code (each, a “Claim,” and collectively, the “Claims”); 
 WHEREAS, the Debtors have determined that a prompt restructuring concerning or impacting, inter alia, the Notes and related Claims
evidenced thereby pursuant to the terms of this Agreement and the term sheet attached hereto as Exhibit C (the “Plan Term Sheet”) would be in the best interests of its creditors and shareholders (such restructuring being, the
“Restructuring”); 
 WHEREAS, the Parties intend to implement the Restructuring through a confirmed plan of
reorganization under chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”), the form and substance of which shall be reasonably satisfactory to the Debtors and the holders of more than a majority of the aggregate
outstanding principal amount of the Claims held by each of (i) the Consenting Noteholders that hold the Holding Notes (the “Requisite Holding Noteholders”) and (ii) the Consenting Noteholders that hold the IHC Second Lien
Notes (the “Requisite Second Lien Noteholders”); 
 WHEREAS, in order to implement the Restructuring, the Debtors
have agreed, subject to the terms and conditions of this Agreement, (i) to prepare and file (a) a plan of reorganization that is consistent in all material respects with this Agreement and the Plan Term Sheet, and which shall be in form
and substance reasonably acceptable to the Requisite Holding Noteholders and the Requisite Second Lien Noteholders (such plan of reorganization together 

 
with all exhibits thereto, the “Plan”) in cases filed under chapter 11 of the Bankruptcy Code by the Debtors (the “Chapter 11
Cases”) and (b) a disclosure statement that is consistent in all material respects with the terms of the Plan and the Restructuring, and which shall be in form and substance reasonably acceptable to the Requisite Holding Noteholders
and the Requisite Second Lien Noteholders (the “Disclosure Statement”), and (ii) to use commercially reasonable efforts to have the Disclosure Statement approved and the Plan confirmed by the United States Bankruptcy Court for
the District of Delaware (the “Bankruptcy Court”) pursuant to an order confirming the Plan which shall be in form and substance reasonably acceptable to the Requisite Holding Noteholders and the Requisite Second Lien Noteholders
(the “Confirmation Order”); 
 WHEREAS, the Parties have engaged in good faith negotiations with the objective of
reaching an agreement with regard to the Restructuring; 
 WHEREAS, each Consenting Noteholder has reviewed, or has had the
opportunity to review, this Agreement and the Plan Term Sheet with the assistance of professional legal advisors of its own choosing; and 
 WHEREAS, each Consenting Noteholder desires to support and vote to accept the Plan, and the Debtors desire to support and pursue the Plan, in each case subject to the terms and conditions set forth herein. 
 NOW, THEREFORE, in consideration of the foregoing and the promises, mutual covenants and agreements set forth herein and for other good and
valuable consideration, the Parties agree as follows: 
 AGREEMENT 
 Section 1. Agreements of the Consenting Noteholders. 
  

	1.1	Ownership. 

 Each Consenting Noteholder represents,
severally and not jointly that, as of the date hereof: 
  

	 	(a)	it is the legal owner, beneficial owner and/or holder of investment authority over, and has the full power to vote, dispose of and compromise, the aggregate principal amount of each
series of Notes set forth opposite such Consenting Noteholder’s name on the signature pages hereof, and the registered holder and the custodial party for such Consenting Noteholder’s Notes are set forth on Exhibit A hereto (which
Exhibit A shall remain confidential unless disclosure is required by court order or such Consenting Noteholder consents); and 

  

	 	(b)	to the actual knowledge of such Consenting Noteholder, there are no other Claims of which it is the legal owner, beneficial owner and/or investment advisor relating to the Debtors
unless such Consenting Noteholder does not possess the full power to vote and dispose of such Claims. 

  

 2 

	1.2	Voting by Consenting Noteholders. 

 As long as a
Termination Event (as defined herein) has not occurred, or has occurred but has been duly waived or cured in accordance with the terms hereof, and provided that each Consenting Noteholder has been properly solicited pursuant to sections 1125 and
1126 of the Bankruptcy Code, each Consenting Noteholder agrees (x) to cast all votes to which it is entitled with respect to its Claims in favor of the Plan in accordance with the voting procedures described in the Disclosure Statement and all
other solicitation materials distributed in connection therewith; (y) to the extent such election is available, not elect on its ballot to preserve Claims in respect of the Notes, if any, that such Consenting Noteholder may own that may be
affected by any releases provided for under the Plan; and (z) not withdraw or revoke its acceptance unless the Plan is modified in any respect in a manner inconsistent with the Plan Term Sheet (other than modifications that are immaterial to
such Consenting Noteholder), or this Agreement is terminated in accordance with its terms. Anything in this Agreement to the contrary notwithstanding, each Consenting Noteholder hereby acknowledges and agrees that all Notes owned by such Consenting
Noteholder are subject to the terms and conditions of this Agreement (whether or not such Notes are listed and/or described on Exhibit A hereto or Annex II to a Joinder Agreement) and no Consenting Noteholder shall be permitted to exclude any
portion of its Notes from the terms of this Agreement. 
  

	1.3	Support of Plan. 

  

	 	(a)	Support of the Restructuring. As long as a Termination Event has not occurred, or has occurred but has been duly waived or cured in accordance with the terms hereof, each of
the Consenting Noteholders agrees that, by having executed and become party to this Agreement, it will instruct its counsel to take, or instruct its counsel to cause to be taken, all actions reasonably necessary to facilitate, encourage or otherwise
support the Restructuring and the transactions contemplated by the Plan Term Sheet, and that it otherwise will not take, or cause to be taken, directly or indirectly, any action opposing, inconsistent with, or that would otherwise delay the
consummation of the Restructuring or the transactions contemplated by the Plan Term Sheet. Without limiting the generality of the foregoing, and subject to the last paragraph of this Section 1.3(a), each Consenting Noteholder agrees that it
will, 

  

	 	(i)	not directly or indirectly seek, solicit, participate in, support or vote in favor of any other plan, termination of the Debtors’ exclusive right to file and solicit
acceptances of a plan of reorganization, sale, proposal or offer of dissolution, winding up, liquidation, reorganization, merger or restructuring of the Debtors that would reasonably be expected to prevent, delay or impede the restructuring of the
Debtors as contemplated by the Plan Term Sheet, the Plan or any other document filed in connection with confirming the Plan that is not inconsistent with this Agreement or the Plan Term Sheet (collectively, an “Alternative
Transaction”); 

  

	 	(ii)	 not directly or indirectly (i) engage in, continue or otherwise participate in any negotiations regarding any Alternative Transaction, (ii) enter into a

  

 3 

	 	 
letter of intent, memorandum of understanding, agreement in principle or other agreement relating to any Alternative Transaction or (iii) withhold,
withdraw, qualify or modify its approval or recommendation of this Agreement, the Plan, the Plan Term Sheet, or the Restructuring; 

  

	 	(iii)	[Intentionally Deleted] 

  

	 	(iv)	not oppose the Debtors’ request for the entry of customary “first day” orders, so long as such “first day” orders are in form and substance reasonably
acceptable to the Requisite Holding Noteholders and the Requisite Second Lien Noteholders (“the “First Day Orders”); 

  

	 	(v)	support entry of an order approving the Disclosure Statement; 

  

	 	(vi)	support confirmation of the Plan and entry by the Bankruptcy Court of the Confirmation Order; 

  

	 	(vii)	support the release provisions contained in the Plan; 

  

	 	(viii)	execute and deliver customary letter(s), in form and substance reasonably acceptable to the Debtors, for distribution to holders of the Notes, stating that such Consenting
Noteholder supports and has committed to vote to approve the Plan; 

  

	 	(ix)	not object to or otherwise commence any proceeding opposing or proposing to alter any of the terms of this Agreement, the Plan Term Sheet, the Disclosure Statement or the Plan; and

  

	 	(x)	not knowingly encourage any other entity to object to, delay, impede, appeal or take any other action, directly or indirectly, to interfere with the implementation of the Plan.

 Anything in this Section 1.3(a) or elsewhere in this Agreement to the contrary notwithstanding, nothing contained herein or in the Plan
Term Sheet shall: (A) limit the ability of a Consenting Noteholder to consult with other Consenting Noteholders or the Debtors; (B) limit the rights of a Consenting Noteholder under any applicable bankruptcy, insolvency, foreclosure or
similar proceeding (including the Chapter 11 Cases), including, without limitation, appearing as a party in interest in any matter to be adjudicated concerning the Debtors or any of their respective assets or properties so long as such appearance
and the positions advocated in connection therewith are not materially inconsistent with the Consenting Noteholder’s obligations hereunder; (C) limit the ability of a Consenting Noteholder to sell or enter into any transactions in
connection with the Notes or any other Claims of such Consenting Noteholder, subject to Section 1.5 hereof; or (D) limit the rights of any Consenting Noteholder under the indenture or any other documents or agreements governing or
evidencing the Notes or other Claims of such Consenting Noteholder (collectively, the “Note Documents”), or constitute a waiver or amendment of any provision of any of the Note Documents. 
  

 4 

	 	(b)	Agreement to Forbear. Each Consenting Noteholder agrees that until this Agreement has been terminated in accordance with the terms herein, it shall not (i) take any
action or otherwise pursue any right or remedy under the Note Documents, including claims against any non-Debtor issuer, guarantor or otherwise liable party under the Note Documents, or (ii) initiate or at the instruction of such Consenting
Noteholder have initiated on its behalf, any litigation or proceeding of any kind with respect to the Holding Notes or the IHC Second Lien Notes, including actions against any non-Debtor issuer, guarantor or otherwise liable party under the Note
Documents, other than to enforce this Agreement. 

  

	 	(c)	Committee Matters. Notwithstanding anything contained in this Agreement to the contrary, (i) the Parties shall be permitted to become members of, and interact with, any
committee of creditors appointed in the Chapter 11 Cases (a “Committee”) and (ii) if a Consenting Noteholder is appointed to, and serves on a Committee, the terms of this Agreement shall not be construed to limit the Consenting
Noteholder’s exercise of its fiduciary duties solely in its role as a member of such Committee, and any exercise of such fiduciary duties shall not be deemed to constitute a breach of the terms of this Agreement; provided, however, that serving
as a member of such Committee shall not relieve such Consenting Noteholder (in its capacity as a Consenting Noteholder and not in its capacity as a member of such Committee) of its obligations under this Agreement unless such obligations are
inconsistent with its duties as a member of a Committee; provided, further, that nothing in this Agreement shall be construed as requiring any Consenting Noteholder to serve on any Committee. 

  

	1.4	Further Acquisition of Claims. 

 Nothing in this
Agreement shall be deemed to limit or restrict the ability or right of a Consenting Noteholder to acquire any additional Notes (“Additional Notes”) or other claims against or interests in the Debtors or any affiliates of the
Debtors; provided, however, that in the event a Consenting Noteholder acquires any such Additional Notes (or other claims or interests) after the date hereof, such Additional Notes (and any other claims or interests)
shall immediately upon such acquisition become subject to the terms of this Agreement. Notwithstanding the foregoing, each Consenting Noteholder, as applicable, acknowledges and agrees that it remains subject to and bound by any standstill or
similar provisions (“Standstill Provisions”) contained in any confidentiality agreement (each, a “Confidentiality Agreement”) executed by the Debtors (or any one of them), on the one hand, and such Consenting
Noteholder, on the other, in accordance with the terms of such Confidentiality Agreement unless such Standstill Provisions have been terminated or expired in accordance with the terms of the Confidentiality Agreement. 
  

	1.5	Transfer of Claims, Interests and Securities. 

 Each
of the Consenting Noteholders hereby agrees, for so long as this Agreement has not been terminated (such period, the “Restricted Period”), not to directly or indirectly, (i) sell, assign, transfer, pledge, hypothecate or
otherwise dispose of any of its Notes or Claims or any option, right or interest (voting, participation or otherwise) therein or (ii) grant any proxies, 

  

 5 

 
deposit any of its Notes in a voting trust or enter into a voting agreement with respect to any of its Notes or Claims (each such transfer, a
“Transfer”), provided, however, that, notwithstanding the foregoing, and subject to the Standstill Provisions (if any) contained in any existing Confidentiality Agreement that have not been terminated or expired in accordance with
the terms of such Confidentiality Agreement, a Consenting Noteholder may Transfer its Notes or Claims if (a) the transferee thereof is a Consenting Noteholder or (b) if the transferee thereof is not a Consenting Noteholder,
(i) executes and delivers to the Debtors a Joinder and (ii) delivers such Joinder to Group before the close of five (5) business days after the relevant Transfer (each such transferee becoming, upon the Transfer, a Consenting
Noteholder hereunder). Group, Holding and IHC, as appropriate, shall promptly acknowledge any such Transfer in writing and provide a copy of that acknowledgement to the transferor. By their acknowledgement of the relevant Transfer, Group, Holding
and IHC, as appropriate, shall be deemed to have acknowledged that their obligations to the Consenting Noteholders hereunder shall be deemed to constitute obligations in favor of the relevant transferee as a Consenting Noteholder hereunder.

  

	1.6	Representations of the Consenting Noteholders. 

 Each Consenting Noteholder represents, severally and not jointly that, as of the date hereof: 
  

	 	(a)	it has full power to vote, dispose of and compromise the aggregate principal amount of its Claims; 

  

	 	(b)	such Consenting Noteholder, or the holder for whom it acts as investment advisor or manager, is either (i) a “Qualified Institutional Buyer” as defined in Rule
144A promulgated under the Securities Act of 1933, as amended (the “Securities Act”), or (ii) an “Accredited Investor” (as such term is defined in subparagraph (1), (2), (3) or (7) of Rule 501
promulgated under the Securities Act); 

  

	 	(c)	the financial situation of such Consenting Noteholder is such that it can afford to bear the economic risk of holding the Distributable New Equity and Holding Warrants (as such
terms are defined in the Plan Term Sheet) (collectively, the “New Securities”); 

  

	 	(d)	the knowledge and experience of such Consenting Noteholder in financial and business matters is such that it, together with its advisors, is capable of evaluating the merits and
risks of the investment in the New Securities; 

  

	 	(e)	such Consenting Noteholder understands that the New Securities are a speculative investment that involve a high degree of risk of loss of its investment therein, that there may be
substantial restrictions on the transferability of the New Securities and, accordingly, it may not be possible to liquidate such Consenting Noteholder’s investment; 

  

	 	(f)	in making its decision to invest in the New Securities hereunder, such Consenting Noteholder has relied upon independent investigations made by such Consenting Noteholder and, to
the extent believed by such Consenting Noteholder to be appropriate, such Consenting Noteholder’s representatives, including such Consenting Noteholder’s own professional, tax and other advisors; 

  

 6 

	 	(g)	such Consenting Noteholder and its representatives, if any, have received and reviewed this Agreement and all exhibits hereto, and have been given the opportunity to examine all
documents and to ask questions of, and to receive answers from, Group, Holding and IHC and their representatives concerning the terms and conditions of the investment in the New Securities; 

  

	 	(h)	it has been advised by Group that (i) the offer and sale of the New Securities has not been registered under the Securities Act, (ii) the offer and sale of the New
Securities is intended to be exempt from registration pursuant to section 1145 of the Bankruptcy Code, and (iii) there is no established market for the New Securities and such a public market for the New Securities may not be established in the
foreseeable future; and 

  

	 	(i)	it is familiar with Rule 144 promulgated by the Securities and Exchange Commission under the Securities Act, as presently in effect, and understands the resale limitations imposed
thereby and by the Securities Act. 

 Section 2. Agreements of the Debtors. 
  

	2.1	Implementation of the Plan. 

 To implement the Plan
Term Sheet, the Debtors hereby agree to use their commercially reasonable efforts to: 
  

	 	(a)	effectuate and consummate the Restructuring on the terms contemplated by this Agreement, the Plan Term Sheet and the Plan; 

  

	 	(b)	file the Plan and the Disclosure Statement with the Bankruptcy Court on or before 5 days after the date on which the Debtors file the Chapter 11 Cases with respect to the
Restructuring in the Bankruptcy Court (the “Petition Date”), or such later date as may be mutually agreed upon by Group and by each of (i) the Requisite Holding Noteholders and (ii) the Requisite Second Lien Noteholders
(the “Filing Date”); 

  

	 	(c)	obtain entry by the Bankruptcy Court of an order approving the Disclosure Statement on or before 40 days following the Filing Date, or such later date as may be mutually agreed upon
by Group and by each of (i) the Requisite Holding Noteholders and (ii) the Requisite Second Lien Noteholders; 

  

	 	(d)	solicit the requisite acceptances of the Plan in accordance with section 1125 of the Bankruptcy Code on or before 75 following the Filing Date, or such later date as may be mutually
agreed upon by Group and by each of (i) the Requisite Holding Noteholders and (ii) the Requisite Second Lien Noteholders; 

  

 7 

	 	(e)	move the Bankruptcy Court to enter the Confirmation Order on or before 90 days following the Filing Date, or such later date as may be mutually agreed upon by Group and by each of
(i) the Requisite Holding Noteholders and (ii) the Requisite Second Lien Noteholders; and 

  

	 	(f)	take no actions materially inconsistent with this Agreement, the Plan Term Sheet and the Plan or the expeditious confirmation and consummation of the Plan; 

provided, however, that the Debtors shall have distributed such documents referenced in this Section 2.1 (which shall include the
Plan, the Disclosure Statement and the Confirmation Order), the First Day Orders, and any documents, motions and orders that are material to the Restructuring and the Chapter 11 Cases, and which shall not include any documents, motions and orders
that are immaterial or primarily covering case administration issues, and afforded reasonable opportunity for comment and review to the respective legal and financial advisors for the Consenting Noteholders in advance of any filing thereof. The
Debtors shall not seek to implement any transaction or series of transactions that would effect a restructuring of the Debtors on terms other than the terms set forth in this Agreement and the Plan Term Sheet. 
  

	2.2	The Debtors’ Fiduciary Obligations. 

 Notwithstanding anything to the contrary contained in this Agreement: 
  

	 	(a)	any directors or officers of the Company (in such person’s capacity as a director or officer of the Company) may take any action to the extent such person reasonably believes
(after consultation with outside legal counsel) such action is required to comply with his or her fiduciary obligations under applicable law (including but not limited to any obligations to creditors, after consultation with such creditors and good
faith consideration of such creditors’ position), and such action shall not be deemed to constitute a breach of the terms of this Agreement. 

  

	 	(b)	the Debtors may terminate their obligations under this Agreement by written notice to the Consenting Noteholders if the Debtors, in good faith exercise of their business judgment,
and after consulting with outside counsel, determine that there is a sufficient risk of non-performance by the Debtors with respect to the financial obligations contemplated under the Plan Term Sheet and the Plan such that the Plan is no longer in
the best interests of the Debtors’ estates. 

 Section 3. Plan Term Sheet. 
 The Plan Term Sheet is incorporated herein by reference and is made part of this Agreement. Each of the Debtors and the Consenting Noteholders has
reviewed, or has had the opportunity to review, the Plan Term Sheet and, by signing below, agrees and acknowledges that it is acceptable to and is approved by such Debtor or Consenting Noteholder. Capitalized terms used herein without definition
shall have the meanings ascribed to any such terms in the Plan Term Sheet, and capitalized terms used in the Plan Term Sheet without definition shall have the meanings ascribed to any such terms in this Agreement. The general terms and conditions of
the Restructuring are set forth in the Plan Term Sheet; provided, however, that the Plan Term Sheet 

  

 8 

 
is supplemented by the terms and conditions of this Agreement. In the event of any inconsistencies between the terms of this Agreement and the Plan Term
Sheet, the Plan Term Sheet shall govern. 
 Section 4. Mutual Representations and Warranties. 
 Each of (i) the Consenting Noteholders, severally and not jointly, represents and warrants to the Debtors and (ii) the Debtors, jointly and
severally, represent and warrant to the Consenting Noteholders that the following statements, as applicable, are true, correct and complete as of the date hereof: 
  

	4.1	Power and Authority. 

 It has all requisite power
and authority to enter into this Agreement and to carry out the transactions contemplated by, and perform its respective obligations under, this Agreement, the Plan Term Sheet and the Plan. 
  

	4.2	Due Organization. 

 Any Party that is not a natural
person is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and that it otherwise has the requisite power and authority to execute and deliver this Agreement and to perform its obligations
hereunder. 
  

	4.3	Enforceability. 

 Subject to the provisions of
sections 1125 and 1126 of the Bankruptcy Code, and Section 8.7 hereof, this Agreement is a legal, valid and binding obligation of such Party, enforceable against it in accordance with its terms, except as enforcement may be limited by
applicable laws relating to or limiting creditors’ rights generally or by equitable principles relating to enforceability. 
  

	4.4	No Consent or Approval. 

 Except as expressly
provided in this Agreement, no consent or approval is required by any other entity in order for such Party to carry out the provisions of this Agreement. 
  

	4.5	Authorization. 

 The execution and delivery by such
Party of this Agreement and the performance of such Party’s obligations hereunder have been duly authorized by all necessary action on its part. 
  

	4.6	Execution. 

 This Agreement has been duly executed
and delivered by such Party. 
  

 9 

	4.7	Governmental Consents. 

 The execution, delivery and
performance by such Party of this Agreement does not and shall not require any registration or filing with, consent or approval of, or notice to, or other action to, with or by, any federal, state or other governmental authority or regulatory body,
except such filings as (i) are identified in the Plan Term Sheet; (ii) may be necessary and/or required under the federal securities laws; and (iii) in connection with the commencement of the Chapter 11 Cases, the approval of the
Disclosure Statement and entry of the Confirmation Order. 
  

	4.8	No Conflicts. 

 The execution, delivery and
performance of this Agreement by such Party does not and shall not (a) violate any provision of law, rule or regulations applicable to it or, as applicable, any of its subsidiaries; (b) with respect to a Party that is not a natural person,
violate its certificate of incorporation, bylaws or other organizational documents or those of any of its subsidiaries; or (c) conflict with, result in a breach of, or constitute (with due notice or lapse of time or both) a default under any
material contractual obligation to which it or, as applicable, any of its subsidiaries is a party, except to the extent such contractual obligation relates to the filing of a case under the Bankruptcy Code or any action taken in furtherance thereof
or the solvency of the Debtors. 
  

	Section 5.	No Waiver of Participation and Preservation of Rights. 

 Except as expressly provided in this Agreement, nothing herein is intended to, does or shall be deemed in any manner to waive, limit, impair or restrict the ability of each of the Parties to protect and preserve its
rights, remedies and interests, including, but not limited to, its Claims against any of the Debtors or its full participation in the Chapter 11 Cases. Without limiting the foregoing sentence in any way, if the transactions contemplated by this
Agreement or otherwise set forth in the Plan are not consummated as provided herein, if a Termination Event occurs, or if this Agreement is otherwise terminated for any reason, the Parties each fully reserve any and all of their respective rights,
remedies and interests and claims against the other Parties hereto. 
  

	Section 6.	Acknowledgement and Agreement. 

  

	 	(a)	This Agreement and the Plan Term Sheet and the transactions contemplated herein and therein are the product of negotiations between the Parties and their respective representatives.
This Agreement is not and shall not be deemed to be a solicitation of votes for the acceptance of a plan of reorganization for the purposes of sections 1125 and 1126 of the Bankruptcy Code or otherwise. The Debtors will not solicit acceptances of
the Plan from any Consenting Noteholder until the Consenting Noteholders have been provided with copies of a Disclosure Statement approved by the Bankruptcy Court. Each Party further acknowledges that no securities of any Debtor are being offered or
sold hereby and that this Agreement does not constitute an offer to sell or a solicitation of an offer to buy any securities of any Debtor. 

  

	 	(b)	Subject to the terms and conditions set forth herein, the Parties agree to negotiate in good faith all of the documents and transactions described in the Plan Term Sheet and in this

 15 

	8.5	Complete Agreement, Interpretation and Modification. 

  

	 	(a)	Complete Agreement. This Agreement, the Plan Term Sheet and the other agreements, exhibits and other documents referenced herein and therein constitute the complete agreement
between the Parties with respect to the subject matter hereof and supersedes all prior agreements, oral or written, between or among the Parties with respect thereto, provided, however, that, to the extent not terminated
or expired by its terms, each Confidentiality Agreement and each indenture and other Note Document shall survive this Agreement and shall continue to be in full force and effect in accordance with its terms irrespective of the terms hereof.

  

	 	(b)	Interpretation. This Agreement is the product of negotiation by and among the Parties. Any Party enforcing or interpreting this Agreement shall interpret it in a neutral
manner. There shall be no presumption concerning whether to interpret this Agreement for or against any Party by reason of that Party having drafted this Agreement, or any portion thereof, or caused it or any portion thereof to be drafted.

 This Agreement may be
executed and delivered (by facsimile or otherwise) in any number of counterparts, each of which, when executed and delivered, shall be deemed an original, and all of which together shall constitute the same agreement. Except as expressly provided in

(b) the Debtors and advisors to the Consenting Noteholders in an unredacted form. 
  

	8.8	Specific Performance. 

 The Parties hereto
acknowledge and agree that money damages would not be an adequate remedy for any breach of the terms of this Agreement and, accordingly, the Parties hereto agree 

  

 16 

 
that each non-breaching Party shall be entitled to specific performance and injunctive or other equitable relief as a remedy for any such breach, including,
without limitation, an order of the Bankruptcy Court or other court of competent jurisdiction requiring any Party to comply promptly with any of its obligations hereunder.

agrees that this Agreement is being executed in connection with negotiations concerning the Restructuring and in contemplation of the possible commencement of the Chapter 11 Cases by the Debtors. Accordingly, (i) the rights granted in this
Agreement are enforceable by each signatory hereto without approval of the Bankruptcy Court, (ii) the exercise of such rights shall not violate the Automatic Stay provisions of the Bankruptcy Code and (iii) subject to their respective
fiduciary out, each Party hereto hereby waives its right to assert a contrary position in the Chapter 11 Cases, if any, with respect to the foregoing. 
  

	8.11	Consideration.

Noteholder hereby acknowledge that no consideration, other than that specifically described herein and in the Plan Term Sheet, shall be due or paid to the Consenting Noteholders for their agreement to vote to accept the Plan in accordance with the

Plan Term Sheet.

11 Cases, and subject to the terms of any Confidentiality Agreement, each of the Parties hereto (a) shall keep the terms and existence of this Agreement, including the Plan Term Sheet, confidential and (b) shall not, and shall cause its
and its affiliates directors, officers, partners, members, employees, agents, advisors, fiduciaries and other representatives not to, without the prior written consent of the other Parties, disclose such information in any manner whatsoever, in

further, that if such disclosure is so required by law or regulation, the Debtors shall afford the Consenting Noteholders a reasonable opportunity to review and comment upon any such announcement or disclosure prior to the Debtors making such
announcement or disclosure. The foregoing shall not prohibit the Debtors from disclosing the approximate aggregate holdings of Notes held by the Consenting Noteholders (but not the identity of individual Consenting Noteholders and their holdings).
