<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Dr. Howard Berger, President and Chief Executive Officer of
RadNet, Inc. noted, &ldquo;We are very pleased to announce the completion of our refinancing transaction. We have successfully
replaced our senior unsecured notes with a second lien term loan and additional borrowings under our existing credit facility,
resulting in lower cash interest obligations of approximately $5.1 million per year. Additionally, the refinancing provides us
with more operating flexibility and lengthens the maturity of our most junior debt capital.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&ldquo;With our first lien term loan due in 2018 and our new

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">On March 20, 2014 RadNet Management received the required consents
to amend the indenture governing its Notes in connection with the Tender Offer and the Consent Solicitation. The terms and conditions
of the Tender Offer and Consent Solicitation are described in the Company's Offer to Purchase and Consent Solicitation Statement,
dated March 7, 2014 (the &ldquo;Offer to Purchase&rdquo;).</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The deadline for the Consent Solicitation expired at 5:00 p.m.,
New York City time, on March 20, 2014 (the &ldquo;Consent Payment Deadline&rdquo;). At the Consent Payment Deadline, $193,464,000
aggregate principal amount of the Notes, representing 96.73% of the outstanding Notes, had been validly tendered and not withdrawn.
As a result of the percentage of outstanding Notes tendered by the Consent Payment Deadline, the required consents were received
with respect to the Consent Solicitation and the Company, RadNet Management, the subsidiaries of RadNet Management that are guarantors,
and U.S. Bank National Association, a national banking association, as trustee (the &ldquo;Trustee&rdquo;) entered into a supplemental
indenture on March 21, 2014 which eliminated or modified certain restrictive covenants (not including the covenant to pay interest
and premium, if any, on and principal of, the Notes when due), and eliminated or modified certain events of default and certain
other provisions contained in the indenture governing the Notes (the &ldquo;Supplemental Indenture&rdquo;). The Supplemental Indenture
was entered into on March 21, 2014 and became operative on March 25, 2014 once the Notes tendered prior to the Consent Payment
Deadline were accepted for payment and paid for by RadNet Management.</P>

&ldquo;Total Consideration&rdquo;), which amount included a consent payment (the &ldquo;Consent Payment&rdquo;) of $30.00 per $1,000
principal amount of Notes. Holders who did not validly tender their Notes on or prior to the Consent Payment Deadline and who tender
their Notes on or prior to 11:59 p.m., New York City time, on April 3, 2014, unless extended or earlier terminated (the &ldquo;Expiration
Date&rdquo;), will be eligible to receive an amount in cash equal to $1,026.88 per $1,000 principal amount of Notes tendered which
is the Total Consideration less the $30.00 Consent Payment. Settlement for all Notes validly tendered after the Consent Payment
Deadline, but on or prior to the Expiration Date, is expected to occur on April 4, 2014. In addition, all Notes accepted for payment
will be entitled to receive accrued and unpaid interest in respect of such Notes from the last interest payment date prior to the
