 WHEREAS, the Parties will enter into an Underwriting Agreement with Goldman Sachs & Co. and Lehman Brothers, Inc. (together, the “Underwriters”), pursuant to which the Underwriters will purchase the

 WHEREAS, the Parties have jointly filed with the Securities and Exchange Commission (the “SEC”) a Registration Statement (the “Registration Statement”) on Form S-3 (Registration No. 333-120164
under the Securities Act of 1933 (the “Act”) relating to the Certificates and the Notes. 
  
 WHEREAS, the Parties may have joint and several liability under the Securities Act of 1933, as amended (the “Act”) or the
Securities and Exchange Act of 1934, as amended (the “Exchange Act”), with respect to the Registration Statement and any related preliminary or final prospectus and/or prospectus supplement used in connection therewith, and under the
indemnification and contribution provisions of the Underwriting Agreement. 
  
 NOW, THEREFORE, in consideration of the promises and agreements hereinafter set forth, the Parties hereby agree as follows: 
  
 Section 1. Indemnification 
  
 (a) In the event that a Party shall become subject to any loss, claim, damage or liability (or actions in respect thereof) (collectively, a
“Loss”) (i) under the Act, the Exchange Act, other Federal or state statutory law or regulation, at common law or otherwise, insofar as such Loss arises out of or is based upon any untrue statement or alleged untrue statement of a material
fact contained in the Registration Statement as originally filed or in any amendment thereof, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not
misleading, or any untrue statement or alleged untrue statement of a material fact contained in any preliminary or final prospectus or prospectus supplement, or in any amendment thereof or supplement thereto, or that arises out of or is based upon
the omission or alleged omission 








 
to state therein a material fact required to be stated therein or necessary to make the statement therein, in light of the circumstances under which they
were made, not misleading, or (ii) under the Underwriting Agreement, the Parties agree to contribute to the aggregate Losses (including legal or other expenses reasonably incurred in connection with investigating or defending same) to which a Party
may be subject pro rata based on the original aggregate principal amount of Notes issued by each Party, and will be responsible for (and to the extent necessary, reimburse the other party, as incurred), for its pro rata share of any legal or other
expenses reasonably incurred by either Party in connection with investigation or defending any such Loss or action; provided, however, that a Party will be solely liable for any Loss (and such Party agrees to indemnify the other Party)
to the extent that any such Loss arises out of or is based upon (x) any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to by such
Party, specifically for inclusion therein, or (y) a breach of a representation, warranty or covenant by such Party under the Underwriting Agreement. For the purposes of this Section 1(a) any information provided by Boston Edison Company will be
treated as information provided by BEC and any information provided by Commonwealth Electric Company will be treated as information provided by CEC. 
  
 (b) If the allocation provided by subsection (a) above is unavailable for any reason, the Parties shall contribute to any such Loss in such proportion as
is appropriate to reflect not only their pro rata share but also the relative fault of each Party in connection with the statements or omissions which resulted in such Loss as well as any other relevant equitable considerations. 
  
 (c) For purposes of this Section 1, each person who controls the Parties
within the meaning of either the Act or the Exchange Act each officer of the Parties who shall have signed the Registration Statement and each director of the Parties shall have the same rights to contribution as the Parties, subject in each case to
the applicable terms and conditions of this paragraph. 
  
 (d)
Promptly after receipt by a Party under this Section 1 of notice of the commencement of any action, such Party will notify the other Party in writing of the commencement thereof; but the failure so to notify the other Party (i) will not relieve the
other Party from liability under paragraph (a) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the other Party of substantial rights and defenses and (ii) will not, in any event,
relieve the other Party from any obligations to the first Party other than the obligations provided in paragraph (a) above. 
  
 Section 2. Miscellaneous 
  
 (a) Amendment. This Agreement may be amended, modified or supplemented by the Parties provided that any such amendment, modification or supplement
shall be in writing and signed (or consented to in writing) by the Parties. 
  
 (b) Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement
shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner adverse to either Party. Upon such determination that any term or other provision is
invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions
contemplated hereby are fulfilled to the fullest extent possible.
