Shaw Synoptic Portfolios 5, L.L.C., hereby agrees, acknowledges and covenants that such Person will not complain, initiate or otherwise pursue any remedies of any type against, any HEC Member who is not one of the Crossover Parties as a result of, or in any way arising out of, the fact of the Crossover Parties’ involvement in the transactions contemplated by this Contribution Agreement, including the contribution by any Crossover Party of their HEC Membership Interests to NEWCO.

6.10         Section 351.  For United States federal income Tax purposes and any applicable state or local income or franchise Tax purposes, the Parties recognize that the contributions described in Section 2.2(b) will be treated as contributions by such HEC Members to NEWCO in exchange for shares of NEWCO Common Stock to which Section 351(a) of the Code applies.  No Party hereto shall file any income Tax Return or otherwise take any position for income Tax purposes that is inconsistent with such treatment unless required to do so pursuant to a “determination” within the meaning of Section 1313(a) of the Code or any corresponding provision of state or local income or franchise Tax Law.  Additionally, each Party hereto agrees to take no action which, alone or in combination with the actions of others, reasonably could be expected to prevent the transactions from qualifying for nonrecognition of gain or loss under Section 351(a) of the Code, including, without limitation, any sale or other disposition of NEWCO Common Stock pursuant to any binding obligation or fixed or definite plan or intention.

6.11         Notification Of Certain Matters.  Each Party will give prompt notice of (a) the occurrence or non-occurrence of any event, the occurrence or nonoccurrence of which would be likely to cause any representation or warranty of such Person contained herein to be untrue or inaccurate in any material respect at or prior to the Effective Time and (b) any material failure of any such Person to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by such Person hereunder.  The delivery or deemed delivery of any notice pursuant to this Section 6.11 shall not be deemed to (i) modify the representations or warranties hereunder of the Party delivering such notice, (ii) modify the conditions set forth in Article VII, or (iii) limit or otherwise affect the remedies available hereunder to the Party receiving such notice.

investigations or proceedings (including any arbitration or mediation or similar proceedings), of any nature whatsoever in law or in equity, whether currently known or unknown, suspected or claimed, whether pursuant to contract, statute or otherwise, in each case, arising out of or relating to this Contribution Agreement and the transactions contemplated hereby.

6.13         Agreements Regarding Tax Matters.

(a)           Prior to the Closing Date, the Sellers’ Representative and NEWCO shall agree on an allocation of the total Purchase Price among HEC’s assets (the “Allocation”).  The Allocation will consider the principles of applicable Internal Revenue Service guidance, including the possibility of asymmetric treatment of the Parties.  If the Sellers’ Representative and NEWCO are unable to reach agreement on the Allocation by the Closing Date, the Allocation shall be submitted to and determined by the Referee.  The Referee shall determine the elements of the Allocation as are disputed within thirty (30) days after the issues are submitted to the Referee, but in each case in accordance with applicable legal principles.  If any objections are submitted to the Referee for resolution, (i) each of NEWCO and the Sellers’ Representative shall furnish to the Referee such workpapers and other documents and information relating to such objections as the Referee may request and are available to that Party or its Affiliates (or its independent public accountants) and will be afforded the opportunity to present to the Referee any material relating to the determination of the matters in dispute and to discuss such determination with the Referee prior to any written notice of determination hereunder being delivered by the Referee; (ii) to the extent that a value has been assigned by NEWCO or the Sellers’ Representative to any item that is submitted to the Referee, the Referee shall not assign a value to such objection that is greater than the greatest value for such objection claimed by either such Party or less than the smallest value for such objection claimed by either such Party; (iii) the determination by the Referee of the calculation of the Allocation as set forth in a written notice delivered to NEWCO and the Sellers’ Representative by the Referee, shall be binding and conclusive on the Parties and shall constitute an arbitral award that is final, binding and unappealable and upon which a judgment may be entered by a court having jurisdiction thereof; (iv) the fees and expenses of the Referee shall be paid by NEWCO in the event that NEWCO’s assertions regarding the Allocation differ by a greater amount from the amount determined by Referee, or by the HEC Members in the event that the Sellers’ Representative’s assertions regarding the Allocation differ by the greater amount from the amount determined by the Referee.  Once finalized, the Allocation shall be binding upon all Parties to this Contribution Agreement and NEWCO and the HEC Members shall report, act and file all Tax Returns, including any amended Tax Returns, in all respects and for all purposes consistent with the Allocation.  No Party shall take any position (whether in audits, on Tax Returns or otherwise) that is inconsistent with the Allocation unless required to do so by Law or, following good faith consultation with the other Parties, in connection with the settlement of a Tax Controversy; provided that each Party shall be entitled to apply such statutory or regulatory allocation provisions as are applicable to such Party.

(b)           For any HEC Tax period ending on or before the Closing Date, the Sellers’ Representative shall prepare or cause to be prepared (in a manner consistent with past practice to the extent consistent with applicable Law), and file or cause to be filed (including causing NEWCO to file) with the appropriate taxing authorities all Tax Returns required to be filed with respect to HEC on or prior to the Closing Date (taking into account extensions) and all

18

Tax Returns for income Taxes or franchise Taxes for any HEC Tax period ending on or before the Closing Date for which the HEC Members are responsible, regardless of when required to be filed (collectively, “Pre-Closing Tax Returns”).  At NEWCO’s request, HEC shall make or cause to be made an election under Section 754 of the Code with respect to the Tax period ended on the Closing Date.  Any amounts payable by HEC in connection with such Pre-Closing Tax Returns shall be paid by HEC.  Any amounts payable by the HEC Members in connection with any such Pre-Closing Tax Returns for income or franchise Taxes shall be paid by such HEC Members.  NEWCO shall have the right to review all Pre-Closing Tax Returns at least fifteen (15) days (or, in the case of Tax Returns other than Tax Returns for income or franchise Taxes for which the HEC Members are responsible, as many days as reasonably practical) prior to the timely filing thereof, and the Parties agree to consult and resolve in good faith any issue arising as a result of the review of such Pre-Closing Tax Returns; provided that the Sellers’ Representative shall have final control in the case of Pre-Closing Tax Returns for income or franchise Taxes for which the HEC Members are responsible, except to the extent the positions taken therein are contrary to Law or to the provisions of this Contribution Agreement; and provided, further, that the Sellers’ Representative shall make any changes to a Pre-Closing Tax Return that are reasonably requested by NEWCO and will have no material adverse effect upon any HEC Member.

(c)           For any HEC Tax period that begins on or before and ends after the Closing Date (“Straddle Period”), NEWCO shall timely prepare or cause to be prepared, and file or cause to be filed (in a manner consistent with past practices to the extent consistent with applicable Law) with the appropriate taxing authorities all Tax Returns required to be filed with respect to HEC (“Straddle Returns”) and shall pay all Taxes due with respect to such Straddle Returns.  The Sellers’ Representative shall have the right to review any such Straddle Returns at least fifteen (15) days (or, in the case of Tax Returns other than Tax Returns for income or franchise Taxes for which the HEC Members are responsible, as many days as reasonably practical) prior to the timely filing of such Straddle Returns, and the Parties agree to consult and resolve in good faith any issue arising as a result of the review of any such Straddle Returns.

(d)           All transfer, documentary, sales, use, registration, value-added and other similar Taxes (including all applicable real estate transfer Taxes) and related fees (including any penalties, interest and additions to Tax) (collectively, “Transfer Taxes”) incurred in connection with the transactions expressly contemplated hereby shall be paid one-half by NEWCO and one-half by the HEC Members.  The Parties agree to cooperate and utilize their commercially reasonable efforts to minimize the Transfer Taxes associated with the transactions contemplated by this Contribution Agreement.

(e)           NEWCO and the HEC Members will cooperate fully, as and to the extent reasonably requested by the other such Party, in connection with any audit, litigation or other proceeding with respect to Taxes in relation to the transactions contemplated hereby (each a “Tax Controversy”), and in connection with the preparation and filing of any Tax Return, or amendment thereto.  Such cooperation will include the retention and (upon the other such Party’s written request) the provision of records and information reasonably relevant to any such audit, litigation or other proceeding, or any such Tax Return or amendment thereto, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder; provided, however, that no such Party shall be

19

required to retain any Tax Returns, supporting workpapers, or other records beyond a time that is thirty (30) days after the expiration of the applicable statute of limitations with respect to a Tax.  NEWCO and the HEC Members further agree, upon request, to use their reasonable efforts to obtain any certificate, including any resale or similar certificate, or other document from any Person as may be reasonably necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated by this Contribution Agreement).  Without limiting the foregoing, the Sellers’ Representative shall control any Tax Controversy with respect to Pre-Closing Tax Returns or Straddle Returns relating to income or franchise Taxes that are payable by the HEC Members, provided that NEWCO shall be entitled to participate in such Tax Controversy (at NEWCO’s own expense) and shall be afforded current access to all correspondence and information in connection  therewith, and provided further that the Sellers’ Representative shall not be entitled to settle any such Tax Controversy in a manner that would materially and adversely impact NEWCO without the prior written consent of NEWCO, which consent shall not be unreasonably withheld.

6.14         HEC Member Expenses.  NEWCO, BCEC and BCEOC, jointly and severally, agree to pay and reimburse the HEC Members for all reasonably documented out-of-pocket fees and expenses incurred by them since June 30, 2010 in connection with the transactions contemplated hereby, the 144A Offering or any other matter reasonably related thereto (including, without limitation, all fees and expenses of its legal counsel, financial advisors, accountants, consultants, agents or other representatives).

6.15         Sellers’ Representative.

(a)           The HEC Members hereby irrevocably nominate, constitute and appoint the Sellers’ Representative as the agent and true and lawful attorney-in-fact of the HEC Members, with full power of substitution, to act in the name, place and stead of the HEC Members for purposes of executing any documents and taking any actions that the Sellers’ Representative may, in its sole discretion, determine to be appropriate in connection with this Contribution Agreement or the transactions contemplated hereby.  The Sellers’ Representative hereby accepts such appointment.

(b)           The HEC Members hereby grant to the Sellers’ Representative full authority to execute, deliver, acknowledge, certify, file and record any and all documents and to settle any disputes or claims for indemnification arising hereunder (all on behalf and in the name of the HEC Members) that the Sellers’ Representative may, in its sole discretion, determine to be appropriate, in such forms and containing such provisions as the Sellers’ Representative may, in its sole discretion, determine to be appropriate (including any amendment to or waiver of rights under this Contribution Agreement or any of the documents contemplated hereby).  Notwithstanding anything to the contrary contained in this Contribution Agreement or any of the documents contemplated hereby:

(i)            NEWCO, BCEC and BCEOC and their respective Affiliates shall be entitled to deal exclusively with the Sellers’ Representative on all matters relating to this Contribution Agreement and the transactions contemplated hereby (including all matters relating to any notice to, or any consent to be given or action to be taken by, the HEC Members); and

20

(ii)           each NEWCO Indemnified Party shall be entitled to rely conclusively (without further evidence of any kind whatsoever) on any document executed or purported to be executed on behalf of the HEC Members by the Sellers’ Representative, and on any other action taken or purported to be taken on behalf of the HEC Members by the Sellers’ Representative, as fully binding upon the HEC Members.

(c)           The HEC Members recognize and intend that the power of attorney granted in Section 6.15(a): (i) is coupled with an interest and is irrevocable; and (ii) may be delegated by the Sellers’ Representative.

6.16         No Outside Reliance.  NEWCO ACKNOWLEDGES THAT IT WILL, SUBJECT ONLY TO THE REPRESENTATIONS, WARRANTIES, COVENANTS AND OBLIGATIONS OF THE HEC MEMBERS HEREUNDER AND UNDER THE AGREEMENTS CONTEMPLATED HEREBY, ACQUIRE THE HEC MEMBERSHIP INTERESTS ON AN “AS IS” BASIS WITH ALL FAULTS IN RELIANCE UPON NEWCO’S INSPECTION THEREOF.  EXCEPT AS OTHERWISE SET FORTH IN THIS CONTRIBUTION AGREEMENT, AND WITHOUT LIMITING THE REPRESENTATIONS AND WARRANTIES OF THE HEC MEMBERS MADE HEREIN, THE HEC MEMBERS MAKE NO OTHER REPRESENTATION OR WARRANTY OF ANY KIND WHATSOEVER WITH RESPECT TO ANY OF THE HEC MEMBERSHIP INTERESTS, HEC’S ASSETS OR BUSINESS, WHETHER EXPRESS OR IMPLIED, INCLUDING ANY REPRESENTATIONS OR WARRANTIES CONCERNING OR WITH RESPECT TO (a) THE VALUE, NATURE, QUALITY OF CONDITION, OR STATE OF REPAIR OF ANY OF HEC’S ASSETS, (b) THE COMPLIANCE OF HEC, OR ANY REAL PROPERTY OWNED OR LEASED BY IT, OR THE OPERATION OF ANY FACILITIES OF HEC, WITH APPLICABLE LAW, OR (c) THE HABITABILITY, MERCHANTABILITY, MARKETABILITY, PROFITABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF ANY PERSONAL OR REAL PROPERTY OWNED OR LEASED BY HEC.  NEWCO HEREBY EXPRESSLY DISCLAIMS THE IMPLIED WARRANTY OF HABITABILITY, THE IMPLIED WARRANTY OF MERCHANTABILITY AND THE IMPLIED WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

9.4           Mitigation.  Each Party entitled to indemnity hereunder shall use reasonable efforts to mitigate any Losses for which it may claim indemnification under this Article IX.  To the extent any Party shall have been determined to have failed to use reasonable efforts to mitigate such Losses, such Party’s right to indemnification hereunder shall be reduced by the portion of such Losses attributable to such failure.
