     -----

includes, but is not limited to, customers, trade practices, pricing and other
competitive practices, trade secrets, computer access and source codes,
financial data and know-how of Yankee Gas and YES, their parents, subsidiaries
and affiliates.

               (b)  Terzic agrees and acknowledges that Yankee Gas and YES are
engaged in a competitive business and that any disclosure, divulgence, use or
revelation of any confidential information would be highly detrimental to Yankee
Gas and YES and that serious loss of business and other damage may result
therefrom.

               (c)  At all times hereafter, Terzic will maintain the
confidentiality of all information relating to the business, customers, trade
practices, pricing and other competitive practices, trade secrets, computer
access and source codes, financial data and know-how of Yankee Gas and YES,
their parents, subsidiaries and affiliates, and Terzic will not, directly or
indirectly, make any disclosure thereof to anyone, or make any use thereof, on
his own behalf or on behalf of any third party, without Yankee Gas' and YES'
prior written consent. Terzic has returned or will immediately return to Yankee
Gas and YES all computers (except the Dell laptop currently in Mr. Terzic's

instructional manuals, and other physical or personal property which he received
or prepared or helped prepare in connection with his employment with Yankee Gas
and YES or his service as an employee of Yankee Gas and YES, their subsidiaries
and affiliates, and Terzic has not retained and will not retain any copies,
duplicates, reproductions or excerpts thereof. Terzic agrees to take all
necessary actions, if required by and at the cost of Yankee Gas and YES, to vest
such property rights in Yankee Gas and YES. This subsection (c) shall not apply
to speeches and articles on utility industry topics written by Terzic during the
course of his employment and available to the public as of the date of this
Agreement.

     ELEVENTH:  Not later than October 2, 1998, Terzic shall submit an itemized
     --------                                                                  
listing of any unreimbursed business expenses incurred by him on behalf of
Yankee Gas and YES.  Within five business days following receipt of such list,
Yankee Gas or YES will reimburse Terzic for all such ordinary and reasonable
business expenses incurred by him through the Resignation Date.

     -------                                                                  
positions with Yankee Gas and YES and their respective subsidiaries and
affiliates as an officer, employee 
<PAGE>
 
or member of any board of directors. As used herein, the term "affiliates" shall
include all utility industry-related organizations with respect to which Terzic
serves at the request of or in connection with the business of either Yankee Gas
or YES but shall not include other non-profit organizations in which Mr. Terzic
continues to serve solely in an individual capacity.

     THIRTEENTH:  Terzic agrees that he shall not make any statements or
     ----------                                                         
comments to the media concerning Yankee Gas, YES, any of the of the Related
Parties, his employment with Yankee Gas and YES, or the termination thereof
without the prior written consent of Yankee Gas or YES, except to generally
endorse and explain the "Statement of Branko Terzic" referred to below.  Nothing
in this Agreement shall prohibit Terzic from media discussions concerning his
plans or planning for future employment nor inhibit him from sharing his
opinions concerning the natural gas industry without mention, directly or
indirectly, of Yankee Gas, YES or any of the Related Persons.

     The parties agree that a mutually-agreed press release relating to Terzic's
termination of employment shall be publicly released by Yankee Energy, and that
concurrently with such release Terzic shall be entitled to publicly release a
separate statement which will be reviewed in advance and approved by Yankee
Energy, such approval not to be unreasonably withheld.

     FOURTEENTH:  The parties recognize that in view of the nature of Terzic's
     -----------                                                              
employment and the nature of the confidential information of Yankee Gas and YES
to which he has had access during the course of his employment, that in the
event of a breach or threatened breach by Terzic of his obligations hereunder,
Yankee Gas or YES shall be entitled, if it so elects to institute and prosecute
proceedings in any court of competent jurisdiction, either in law or in equity,
to obtain damages for any breach or to enforce the specific performance thereof.
Without limiting the generality of the foregoing, the parties acknowledge that a
breach or threatened breach by Terzic of any of the obligations set forth in
paragraph TENTH of this Settlement Agreement would cause irreparable harm to
Yankee Gas and YES, that Yankee Gas and YES have no adequate remedy at law, and,
therefore, Yankee Gas and YES would be entitled to injunctive relief with
respect thereto.

     FIFTEENTH:  The parties agree to keep the terms of this Settlement
     ---------

legal counsel or tax accountants on a confidential basis or as may be necessary
to obtain enforcement thereof, (ii) Yankee Gas and YES may disclose the terms
hereof to the extent required, in the opinion of counsel, by applicable law or
regulation, and (iii) Terzic may disclose the terms hereof to members of his
family (and Terzic shall be responsible for any violation of the confidentiality
provisions of this Agreement by family members) or, upon prior notice to Yankee
Energy, in response to a subpoena or court order which Yankee Energy shall have
a reasonable opportunity to contest.

     SIXTEENTH:  As a material inducement to enter into this Settlement
     ---------

forth herein, Terzic knowingly and voluntarily releases, acquits and forever
discharges Yankee Gas, YES and the Related Persons, from any and all charges,
complaints, claims, liabilities, obligations, promises,

unknown, suspected or unsuspected, foreseen or unforeseen, matured or unmatured
(collectively, "Claims"), which, from the beginning of the world up to and
including the date hereof, exists, have existed, or may arise from any matter
whatsoever occurring, including, but not limited to, any Claims arising out of
or in any way related to (i) the Employment Agreement; (ii) the ownership or
purported ownership of any stock of Yankee Gas and YES or any of their parents,
subsidiaries or affiliates; (iii) the Plans; and (iv) Terzic's employment with
Yankee Gas and YES and the conclusion thereof, which Terzic or any of his heirs,
executors, administrators, successors and assigns ever had, now has or at any
time hereafter may have, own or hold against Yankee Gas, YES or any of the
Related Persons. By executing this Settlement Agreement, Terzic is waiving all

state and local labor and anti-discrimination laws and any other restriction on
the right to terminate employment, including, without limitation, the Age
Discrimination in Employment Act ("ADEA"), the Family and Medical Leave Act,

Employees Retirement Income Security Act of 1974, and the Connecticut Fair
Employment Practices Act, all as amended, including but not limited to, claims

orientation, marital status, mental or physical disability and harassment based
on any of these categories or any other protected category and any Claims based
on the right to the payment of wages, vacation, pension benefits or any other
employee benefit. Nothing herein shall release any party from any obligation
under this Settlement Agreement.

     SEVENTEENTH:  The parties and Related Persons agree that they will not
     -----------

communicate any information (whether written or oral) that disparages or is
likely in any way to harm the reputation of any party or any of the Related
Persons.

     EIGHTEENTH:  In the event of any breach by Yankee Gas and YES, Terzic may
     ----------                                                               
only institute an action for specific enforcement of the terms of this
Settlement Agreement and seek damages resulting from such breach.  Terzic may
not institute any proceeding based on the claims related to his employment with
Yankee Gas and YES or the termination thereof.

     NINETEENTH:  In the event that Terzic breaches any of his obligations set
     ----------

obligated to pay the Separation Payment (if it has not already been paid), and
Yankee Gas and YES shall be entitled to recover the Separation Payment as
liquidated damages for any such breach, together with all costs and attorneys'
fees incurred by Yankee Gas and YES or any of the Related Persons.

     TWENTIETH:  In the event of Terzic's death, Terzic's estate, designated

and enforced under the laws of the State of Connecticut, without regard to its
conflict of laws rules.

     TWENTY-FOURTH:  In the event that any one or more of the provisions of this

validity, legality and enforceability of the remaining provisions will not in
any way be affected or impaired thereby.  Moreover, if any one or more of the

and that the parties shall have no further obligations under the Employment
Agreement.  The parties may execute this Settlement Agreement in counterparts.
