Item 1.01 Entry into a Material Definitive Agreement.
- -----------------------------------------------------

At its March 28, 2005 meeting, the Compensation and Executive Development
Committee of the Board of Directors (CEDC) of UIL Holdings Corporation (UIL
Holdings) approved, among other actions, the following:

1. The CEDC approved participants, targets and measures for annual incentives
   to be paid in 2006 for 2005 performance under the UIL Holdings Senior
   Executive Incentive Compensation Program.  The annual incentive awards will
   become payable if corporate performance goals related to earnings per
   share, cash flow, disposition of certain assets and certain individual
   goals are achieved.  If a specified level of earnings per share is
   achieved, certain individual goals will be deemed achieved "at maximum"
   allowing the CEDC to exercise negative discretion in determining a
   component of an annual incentive award.  The individual goals include
   assessment of leadership and an assessment of the level of achievement of
   strategic objectives by the Chief Executive Officer and the Chief Financial
   Officer and, in the case of other executive officers, achievement of a
   variety of performance measures applicable to the business units for which
   the executive officer has principal responsibility.

2. The CEDC made performance share grants under the UIL Holdings Long-Term
   Incentive Program, or in the case of Messrs. Woodson and Nicholas, the
   UIL Holdings CEO/CFO Long-Term Incentive Program, as detailed below:



                                                                                      Target Number of
                                                                                 Performance Shares Granted
   Name                            Position
   ----------------------------------------------------------------------------------------------------------
                                                                                     
   Nathaniel D. Woodson            President and Chief Executive Officer                   9,200
   Richard J. Nicholas             Executive Vice President and Chief Financial            5,600
                                   Officer
   Gregory W. Buckis               Vice President and Controller                           1,600
   Susan E. Allen                  Vice President Investor Relations, Corporate            1,600
                                   Secretary and Assistant Treasurer
   Deborah Hoffman                 Vice President Audit Services and Chief                   800
                                   Compliance Officer


   In general, the performance shares granted vest over, and the
   associated performance measures pertain to, the three-year period
   ending December 31, 2007. The issuance of performance shares upon
   vesting, if any, will be based upon the achievement by two of UIL
   Holdings' business units, The United Illuminating Company (UI) and
   Xcelecom, Inc. (Xcelecom), of certain performance goals, with payment
   to UIL Holdings' executives being based on the composite results of
   such programs weighted 70% and 30%, respectively. The performance
   measure relating to UI is based on the average annual return on equity
   and the performance measure relating to Xcelecom is based on the
   percentile ranking achieved by Xcelecom, with respect to two equally
   weighted performance measures, namely, pre-tax income as a percent of
   sales and free cash flow as a percent of sales, as compared against an
   established group of comparable companies.


   The actual number of performance shares issued will be based on the level
   of performance achieved, but shall not exceed a pre-determined amount.

   The target number of performance shares granted to Mr. Nicholas shown
   in the table above includes a performance share grant payable based on
   the achievement of total shareholder return (TSR) performance goals.
   Final payout, if any, under this grant is determined based on the
   relative TSR percentile achieved by UIL Holdings as compared against an
   established group of comparable companies selected by the CEDC for the
   period from January 1, 2005 through December 31, 2006. The target
   number of shares payable to Mr. Nicholas pursuant to this grant is
   3,700 shares with the maximum allowable payout being 200% of the
   target.


3. The CEDC approved increases effective April 1, 2005 in the base salary for
   the following executive officers:

     - Mr. Woodson's base salary increased to $650,000.
     - Mr. Nicholas' base salary increased to $227,000.
     - Mr. Buckis' base salary increased to $185,000.
     - Ms. Allen's base salary increased to $180,000.
     - Ms. Hoffman's base salary increased to $141,000.
