Exhibit 10.1
FIRST AMENDMENT

Reference is made to that certain Credit Agreement, dated as of September 30,
2010 (as amended and modified from time to time, the "Credit Agreement"), by and
among Vectren Capital Corp., an Indiana corporation (the "Borrower"), the
Guarantor, the Lenders and Wells Fargo Bank, National Association, as
administrative agent (the "Administrative Agent").  Capitalized terms used
herein without definition shall have the meanings ascribed to such terms in the
Credit Agreement.

The parties hereto agree that a mutual error was made in drafting Section
7.13(i) of the Credit Agreement and that Section 7.13(i) of the Credit Agreement
is hereby amended and restated in its entirety to read as follows:

(i)           in addition to Liens covered by (a)-(h) above, Liens securing
Indebtedness not exceeding 15% of the Guarantor's Consolidated Net Worth in the
aggregate outstanding at any time.

This First Amendment is a Loan Document.  All references in the Credit Agreement
and the other Loan Documents to the Credit Agreement shall be deemed to refer to
the Credit Agreement as amended hereby.  Except as modified hereby, all of the
terms and provisions of the Credit Agreement and the other Loan Documents shall
remain in full force and effect.

This First Amendment may be executed by the parties hereto in several
counterparts, each of which shall be deemed to be an original and all of which
shall constitute together but one and the same agreement.  Delivery of an
executed counterpart by telecopy or other secure electronic format (.pdf) shall
be as effective as an original.  This First Amendment shall be governed by the
laws of the State of Illinois and shall become effective upon the Administrative
Agent's receipt of counterparts hereof duly executed by the Required Lenders and
each of the Loan Parties.
