ITEM 2.03 CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN
OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT.

         Effective September 14, 2005, we established a new $20 million working
capital revolving credit facility with Bridge Healthcare Finance, or Bridge, a
specialty lender in the healthcare industry. Upon the establishment of this
credit facility, we borrowed $15.5 million which was used to pay off the entire
balance of our existing credit facility with Wells Fargo Foothill. Upon
repayment, the existing credit facility with Wells Fargo Foothill was
terminated. Additionally, Bridge provided us approximately $0.8 million in the
form of a term loan, which we used to pay the balance of a term loan owed to
Wells Fargo Foothill. Under the Bridge revolving credit facility, we may borrow
the lesser of 85% of the net collectible value of eligible accounts receivable
plus one month capitation receipts for the preceding month, or $20,000,000. An
overadvance subline is available not to exceed $2,000,000, so long as after
giving effect to the overadvance subline, the revolver usage does not exceed
$20,000,000. Eligible accounts receivable shall exclude those accounts older
than 150 days from invoice date and will be net of customary reserves. Dr.
Berger, our president and chairman of the board of directors, has agreed to
personally guaranty the repayment of any monies under the overadvance subline.
Advances under the revolving loan bear interest at the base rate plus 3.25%. The
base rate refers to the prime rate publicly announced by La Salle Bank National
Association, in effect from time to time. The term loan bears interest at the
annual rate of 12.50%. The revolving credit facility is collateralized by
substantially all of our accounts receivable and requires us to meet certain
financial covenants including minimum levels of EBITDA, fixed charge coverage
ratios and maximum senior debt/EBITDA ratios. The term loan is collateralized by
specific imaging equipment used by us at certain of our locations. As part of
the Bridge Healthcare financing, our financial covenants were revised with our
creditors, including GE, US Bank and Post Advisory Group.
