to impede, interfere with, delay, postpone or adversely affect the transactions contemplated by the Purchase Agreement and certain

(ii) the termination of the Purchase Agreement and (iii) such date and time as designated by Hitachi (the &ldquo;<B><I>Expiration

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">BASKING RIDGE, N.J., (March 16, 2017) &ndash; Caladrius Biosciences,
Inc. (NASDAQ: CLBS) (&ldquo;Caladrius&rdquo; or the &ldquo;Company&rdquo;), a cell therapy company with a select therapeutic development
pipeline focused on immune modulation,&nbsp;announces that the Company has signed a definitive agreement (the &ldquo;Agreement&rdquo;)
in which its remaining 80.1% ownership interest in its PCT, LLC (&ldquo;PCT&rdquo;) subsidiary will be purchased by Hitachi Chemical
Co. America, Ltd. (&ldquo;Hitachi Chemical&rdquo;) for $75 million in cash; and in addition there is the potential for Caladrius
to receive an additional cash payment of $5 million if PCT achieves a certain revenue-based milestone. PCT is an industry-leading
cell therapy development and manufacturing services provider and is currently 19.9% owned by Hitachi Chemical. This transaction
will redefine Caladrius as a cell therapeutics-only development company with multiple proprietary technology platforms and significant
capital resources to fund future programs.</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">A $5 million payment from Hitachi Chemical to Caladrius was
triggered upon signing the Agreement and $70 million is due upon closing the transaction, $5 million of which will be placed into
escrow to cover indemnification claims of Hitachi Chemical, if any. The closing is expected to occur in May 2017 subject to approval
by Caladrius&rsquo; shareholders and customary closing conditions.</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">In addition, the Agreement provides for Hitachi Chemical/PCT
to continue to provide development and manufacturing services to Caladrius in connection with Caladrius&rsquo;s T regulatory cell
program, for a period of seven years after closing.</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">Caladrius intends to use the proceeds from this transaction
for working capital including, among other things, to complete its currently enrolling Phase 2 trial (the Sanford Project: T-Rex
Study) for its lead product candidate, CLBS03 for the treatment of recent-onset type 1 diabetes, to judiciously and opportunistically
identify clinical development pipeline candidates and to fully eliminate the Company&rsquo;s remaining $5.5 million of outstanding
debt.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&ldquo;Hitachi Chemical&rsquo;s purchase of our remaining interest
in PCT unlocks the value of this asset for our Company both by transforming Caladrius into a well-capitalized pure play therapeutics
development company and by eliminating our need to contribute the tens of millions of dollars of future capital investment in PCT
needed for it to fully realize its cell therapy commercial manufacturing growth goals,&rdquo; said David J. Mazzo, PhD, Chief Executive
Officer of Caladrius. &ldquo;The transaction provides considerable non-dilutive capital to fund the execution of our ongoing Phase
2 trial while also allowing us to exploit compelling therapeutic prospects.&rdquo;</P>
