Business Wire

DENVER -- May 08, 2013

Prospect Global Resources Inc. (NASDAQ: PGRX) announced today that on May 2,
2013 it had received a $5 million subordinated loan which meets a required
funding milestone required under its senior debt and plans to commence a $12
million rights offering this week in which all shareholders of record as of
May 16, 2013 will receive their pro rata share of rights to subscribe for
units consisting of a share of common stock and one-half a warrant to purchase
a share of common stock. A unit is priced at $0.22 (27% below the last
reported trading price on May 7, 2013) and each warrant is exercisable for one
year following the closing of the rights offering at $.35 per share. The
warrants are immediately detachable from the shares of common stock purchased
in the rights offering. Holders who purchase their entire pro rata share of
the units may exercise an over-subscription right to subscribe for
unsubscribed units to the extent available. The lenders of the subordinated
loan have agreed to convert their subordinated notes into the securities
offered in the rights offering subject to shareholder approval of such
conversion at our annual meeting of shareholders, expected to occur in July
2013.

Two existing PGRX stockholders, Very Hungry LLC and Scott Reiman 1991 Trust,
loaned the Company $5 million on May 2, 2013 in exchange for subordinated
notes in the aggregate principal amount of $5.5 million and adjustments to all
of their warrants to purchase common stock to an exercise price of $0.25 and a
termination date of August 1, 2016.

The rights offering will be conducted via an existing effective shelf
registration statement. Each shareholder will receive 0.751% of a subscription
right for each share held. The subscription rights are not transferable and
will be evidenced by subscription rights certificates. Prospect will mail
rights offering materials, including a prospectus supplement and a
subscription rights certificate, to the record holders on or about May 10,
2013.

In addition to the rights offering, Prospect intends to conduct an
underwritten public offering in the next few weeks. The proceeds from the
rights offering and the public offering are expected to be used to continue to
fund Prospect's definitive feasibility study, make mandatory repayments of
outstanding indebtedness, pay the expenses associated with the rights offering
and the public offering and for general working capital purposes.

of an offer to buy, any securities, nor shall there be any sale of securities
mentioned in this press release in any state in which such offer, solicitation
or sale would be unlawful prior to registration or qualification under the
