UNSECURED PROMISSORY NOTE

 

                $                  November 14, 2013

FOR VALUE RECEIVED, subject to the terms and conditions stated below,
GreenHunter Resources, Inc., a Delaware corporation (the “Company” or the
“Maker”), hereby promises to pay to the order of [•] (the “Holder”), at the
Holder’s address stated in this Note or such other address as the holder of this
unsecured note (the “Note”) shall designate from time to time in lawful money of
the United States of America in immediately available funds, on November 14,
2014 (the “Maturity Date”), the principal amount of [•] Dollars and No/100
Dollars ($[•]) with interest on the principal amount from the date hereof (the
“Interest Rate”) to accrue at the rate of fifteen percent (15%) per annum simple
interest until the outstanding principal balance and any accrued interest are
paid in full; provided that the Interest Rate shall accrue at the lower of
(i) the rate of seventeen percent (17%) per annum simple interest or (ii) the
maximum rate permitted by applicable law, during any period in which an Event of
Default (as defined below) continues. Interest shall be calculated on the basis
of actual number of days elapsed over a year of 360 days, with months of 30
days. All payments received by the Holder hereunder will be applied first to
costs of collection, if any, and the balance to accrued interest and then to
principal.

Payments on this Note shall be made as follows:

Accrued but unpaid interest shall be payable monthly on the first of each month
of the term of this Note. Principal and remaining accrued but unpaid interest
shall be due and payable on the Maturity Date.

The Maker may prepay this Note, in whole or in part, at any time before the
Maturity Date. Any optional prepayment (and, as applicable, any payment or
prepayment required in connection with an Event of Default (as defined below))
made on or prior to the Maturity Date shall be accompanied by a prepayment fee
equal to all interest on this Note that would have been due after such
prepayment through the end of the Maturity Date, if no payment of principal was
made prior to the end of the Maturity Date, calculated based upon the Interest
Rate in effect as of such prepayment.

 

1. Events of Default. The outstanding principal balance on this Note (together
with all interest accrued thereon) shall, at the option of the Holder hereof,
become immediately due and payable without notice or demand, upon the happening
of any one of the following specified events (each, an “Event of Default”):

 

  (i) the occurrence of a default under the terms of the Note;

 

  (ii) a material breach by the Company of any provision of the Pledge and
Security Agreement, provided that such breach shall not be deemed an Event of
Default, if such breach is cured prior to the thirty-first (31st) day following
written notice of such breach from the Holder or the Collateral Agent;

 

  (iii) the making by the Company of a general assignment for the benefit of
creditors;

 

  (iv) the filing of any petition or the commencement of any proceeding by the
Company or any endorser or guarantor of this Note for any relief under any
bankruptcy or insolvency laws, or any laws relating to the relief of debtors,
readjustment of indebtedness, reorganizations, compositions, or extensions;

 

  (v) the filing of any petition or the commencement of any proceeding against
the Company or any endorser or guarantor of this Note for any relief under any
bankruptcy or insolvency laws, or any laws relating to the relief of debtors,
readjustment of indebtedness, reorganizations, compositions, or extensions,
which proceeding is not dismissed within sixty (60) days; or

 

  (vi) any acquisition of the Company, whether by merger, sale of assets or
other transaction.

--------------------------------------------------------------------------------

Upon the occurrence of any Event of Default (other than an Event of Default as
specified in Section 1(iv) or Section 1(v)) and so long as such Event of Default
is continuing, the Holder may, at its option and upon written notice of
acceleration given to the Company, declare the entire unpaid portion of the
principal amount and all unpaid accrued interest under the Notes due and
payable. If an Event of Default specified in Section 1(iv) or Section 1(v)
occurs and is continuing, then the entire unpaid portion of the principal amount
and all unpaid accrued interest under the Notes shall automatically, and without
any notice or any other action on the part of the Holder, become due and payable
immediately. Prior to or after any notice of acceleration given to the Company,
the Holder may waive any Event of Default that has occurred hereunder and its
consequences. Whenever any Event of Default hereunder shall have been waived as
permitted by this Section 1, such Event of Default shall for all purposes of
this Note be deemed to have been cured and to be not continuing.

 

2. Representations and Warranties of the Company. The Company hereby represents
