                        ATTACHMENT TO PART IV-ITEM (3) OF
                                   FORM 12B-25
                                        
                               Halifax Corporation
                                        
                      WITH RESPECT TO ITS FORM 10-K FOR THE
                            YEAR ENDED MARCH 31, 2005
                                        
                                        
The Registrant estimates that its results of operations for the fiscal year
ended March 31, 2005, as reflected in its consolidated statements of operations
to be included in its Form 10-K for the fiscal year ended March 31, 2005, will
reflect the following changes:

For the fiscal year ended March 31, 2005, the registrant expects to report that
it incurred an operating loss of approximately $1,541,000 compared to operating
income of approximately $1,054,000 for the fiscal year ended March 31, 2004.
The loss for the fiscal year ended March 31, 2005 was primarily a result of
costs associated with the start-up of a new, long-term, enterprise maintenance
contract and certain unanticipated service delivery costs which exceeded the
estimates the registrant utilized in pricing this contract, increases in
reserves for inventory obsolescence and the abandonment of certain office space.

In addition, as a result of the foregoing, for the fiscal year ended March 31,
2005, the Registrant expects to report that it incurred a net loss of
approximately $1,411,000 compared to a net income of $4,228,000 for the fiscal
year ended March 31, 2004.

Also, as a result of the foregoing, for the fiscal year ended March 31, 2005,
the Registrant expects to report a loss per common share on a fully diluted
basis of approximately $.46 compared to earnings per common share on a fully
diluted basis of approximately $1.53, for the fiscal year ended March 31, 2004.
