                   NON-NEGOTIABLE CONVERTIBLE PROMISSORY NOTE

                                                         April 30, 2007

      1.    Loan. FOR  VALUE RECEIVED, the undersigned, Rocky Mountain Minerals,
Inc.,  a Wyoming  corporation,  with its  address  at 2480  North  Tolemac  Way,
Prescott,  Arizona  86305  (referred to herein as  "Borrower"),  promises to pay
Great  Missenden  Holdings  Pty Ltd,  with an address  at Level 25, 500  Collins
Street, Melbourne,  Victoria,  Australia, 3000 ("Lender"),  the aggregate unpaid
principal of all Loans (as hereinafter  defined) made from Lender to Borrower on
June 30,2008 (the "Maturity Date"),  subject to Borrower's  prepayment rights as
set forth below, and interest on the unpaid principal balance of this promissory
note  ("Note")  at a rate equal to nine (9%)  percent per annum.  The  principal
balance then outstanding  under this Note plus accrued but unpaid interest shall
be paid in full on the Maturity Date.

      Lender  shall  advance to  Borrower  the  principal  sum of Three  Hundred
Thousand  ($300,000) US Dollars as follows:  $75,000 on April 30, and $75,000 on
each of May 31,2007,  June 30,2007, and August 31,2007 (the "Loans");  provided,
however, that the Borrower may, in its sole discretion, waive the advancement of
any or all of the  aforementioned  installments  upon  written  notice  given to
Lender 2 days prior to the applicable advance, in which case Lender shall not be
entitled to make such advance.  The Borrower shall record the date and amount of
all such advances and send a written confirmation thereof to Lender.

            Notwithstanding  any  other  provision  hereof,   interest  paid  or
becoming due  hereunder  shall in no event exceed the maximum rate  permitted by
applicable  law.  All amounts due  hereunder  are payable in lawful money of the
United States of America to the Lender at the address above indicated.




      2.    Conversion. (a)  Subject  to  subparagraph  (h)  below,  at any time
before  the  Maturity  Date,  the  Lender  shall  have  the  right,  in its sole
discretion,  to convert the entire then  outstanding  principal  balance of this
Note (if such balance is outstanding at the time of such conversion) into shares
of the Borrower's  common stock,  $.001 par value per share ("Common  Stock") of
the Borrower,  at a conversion price equal to US $0.025 (the "Conversion Price")
per share, subject to adjustment as described below. It is understood and agreed
that such Conversion shall not avoid the obligation of the Lender to advance the
full amount of the Loans.

            (b)   Lender may convert the above specified  amount of this Note at
the then  applicable  Conversion  Price by the surrender of this Note  (properly
endorsed) at the principal  office of the  Borrower,  or at such other agency or
office of the  Borrower  in the United  States of America  as the  Borrower  may
designate by notice in writing to the Lender at the address of Lender  appearing
herein.  In the  event  of  the  conversion  of  this  Note,  a  certificate  or
certificates  for the  securities  into  which  this  Note is so  converted,  as
applicable,  registered  in the name of the Lender,  shall be  delivered  to the
Lender as soon as  practicable  after the  receipt by  Borrower of this Note and
Lender's written request for conversion.

            (c)   If  the  Borrower, at any time while this Note is outstanding,
(A) shall pay a stock dividend or otherwise make a distribution on shares of its
Common Stock,  which  dividend or  distributions  is payable in shares of Common
Stock, (B) subdivide  outstanding shares of Common Stock into a larger number of
shares or (C) combine  (including  by way of reverse  stock  split)  outstanding
shares of Common  Stock  into a smaller  number of shares,  then the  Conversion
Price as then in effect shall be adjusted by  multiplying  it by a fraction,  of
which the  numerator  shall be the number of shares of Common  Stock  (excluding
treasury  shares,  if any)  outstanding  before  such  event  and of  which  the
denominator  shall be the number of shares of Common Stock  (excluding  treasury
shares, if any) outstanding after such event.

            (d)   Except for the merger described in subparagraph  (h) below, in
case of any  consolidation  or  merger  of the  Borrower  with  or into  another
corporation  or entity,  or the  conveyance of all or  substantially  all of the
assets of the  Borrower  to  another  corporation  or  entity,  in  either  case
resulting in a conversion,  extinguishment or exchange of the outstanding shares
of  Common  Stock,  or any  other  re-classification  of the  Common  Stock  not
described  above,  this Note shall  thereafter be convertible into the number of
shares of stock or other  securities or property to which a holder of the number
of shares of Common Stock of the Borrower  deliverable  upon  conversion of this
Note   immediately   prior  to  such   consolidation,   merger,   conveyance  or
reclassification  would  have been  entitled  upon such  consolidation,  merger,
conveyance or reclassification;  and, in any such case,  appropriate  adjustment
shall be made in the application of the provisions herein set forth with respect
to the rights and interest  thereafter  of the holders of this Note,  to the end
that the provisions set forth herein shall be thereafter  applicable,  as nearly
as  reasonably  may be, in  relation  to any  shares of stock or other  property
thereafter deliverable upon the conversion of this Note.

            (e)   Any  adjustment  to  the Conversion Price made pursuant to the
adjustment provisions of this Section 2 shall become effective immediately after
the record date for the


                                        2


determination of stockholders  entitled to receive such dividend or distribution
and shall become effective immediately after the effective date in the case of a
subdivision, combination or re-classification.

            (f)   The  Borrower  covenants that it will at all times reserve and
keep available out of its authorized and unissued  shares of Common Stock solely
for the  purpose  of  issuance  upon  conversion  of this  Note,  each as herein
provided,  free from preemptive rights or any other actual  contingent  purchase
rights of persons other than the Lender,  not less than such number of shares of
the Common Stock as shall be issuable  upon the  conversion  of the  outstanding
principal  amount of this  Note,  to the extent  such  conversion  is  permitted
hereunder.  The Borrower covenants that all shares of Common Stock that shall be
so issuable shall, upon issue, be duly and validly authorized,  issued and fully
paid, nonassessable.

            (g)   Except  with  respect  to the merger described in subparagraph
(h)  below,  if (i)  the  Borrower  shall  declare  a  dividend  (or  any  other
distribution)  on the Common  Stock;  (ii) the Borrower  shall declare a special
nonrecurring  cash dividend on or a redemption  of the Common  Stock;  (iii) the
Borrower shall  authorize the granting to all holders of the Common Stock rights
or warrants to  subscribe  for or  purchase  any shares of capital  stock of any
class or of any  rights;  (iv) there shall be a  reclassification  of the Common
Stock, any consolidation or merger to which the Borrower is a party, any sale or
transfer  of all or  substantially  all of the  assets of the  Borrower,  or any
compulsory  share  exchange,  in each  such case  whereby  the  Common  Stock is
converted  into other  securities,  cash or property;  or (v) the Borrower shall
authorize the voluntary or involuntary dissolution, liquidation or winding up of
the affairs of the Borrower;  then, in each case, the Borrower shall cause to be
filed at each office or agency  maintained for the purpose of conversion of this
Note,  and shall  cause to be mailed to the Lender at its last  address as shall
appear upon this Note records of the  Borrower,  at least 10 calendar days prior
to the  applicable  record or effective  date  hereinafter  specified,  a notice
stating  (i) the date on  which a  record  is to be  taken  for the  purpose  of
receiving such dividend,  distribution,  redemption, rights or warrants, or if a
record is not to be taken,  the date as of which the holders of the Common Stock
of record to be entitled to such dividend,  distribution,  redemption, rights or
warrants are to be determined,  or (ii) the date on which such reclassification,
consolidation,  merger, sale, transfer, share exchange, dissolution, liquidation
or winding up is expected to become effective or close, and the date as of which
it is expected  that  holders of the Common Stock of record shall be entitled to
exchange their shares of the Common Stock for securities, cash or other property
deliverable upon such reclassification,  consolidation,  merger, sale, transfer,
share  exchange,  dissolution,  liquidation  or winding up,  provided,  that the
failure to mail such  notice or any defect  therein  or in the  mailing  thereof
shall not affect the validity of the corporate  action  required to be specified
in such notice.

            (h)   In the  event  that the  shareholders  of  Borrower  adopt and
approve a plan of merger  pursuant to which the Borrower  merges with and into a
wholly owned Delaware subsidiary ("Newco"), and pursuant to such plan of merger,
the holders of the common stock of the Borrower are to receive  shares of common
stock  of  Newco,  then  effective   immediately  prior,  and  subject  to,  the
consummation  of such  merger,  this Note  shall  automatically  convert in full
(including all


                                        3


outstanding   principal  and  interest  thereon)  into  such  number  shares  of
Borrower's common stock which would entitle the Lender to receive in such merger
such number of shares of Newco's  common stock equal to one percent of the total
outstanding shares of Newco's common stock immediately  following the merger for
each  $30,000  of  outstanding  principal  under  this  Note at the time of such
merger, up to a total often percent. Upon such automatic  conversion,  this Note
shall  terminate and be cancelled in full,  without any further action by Lender
or Borrower,  and all of Borrower's  obligations and liabilities hereunder shall
terminate in full upon such automatic conversion.

            (i)   The issuance of certificates for shares of the Common Stock or
other  securities on conversion of this Note shall be made without charge to the
Lender for any documentary stamp or similar taxes that may be payable in respect
of the issue or delivery of such  certificate,  provided that the Borrower shall
not be  required  to pay any tax that may be payable in respect of any  transfer
involved in the issuance and delivery of any such certificate upon conversion in
a name other than that of the Lender and the  Borrower  shall not be required to
issue or  deliver  such  certificates  unless  or until the  person  or  persons
requesting the issuance  thereof shall have paid to the Borrower or its designee
the  amount of such tax or shall have  established  to the  satisfaction  of the
Borrower that such tax has been paid.

            (j)   Upon  conversion  hereunder,  the  Borrower  may  issue  stock
certificates representing fractions of shares of the Common Stock.

            (k)   Nothing  herein shall limit any right granted to Lender by any
other instrument or document or by law or equity.

      3.    Prepayment.  Borrower  may, at any time prior to the Maturity  Date,
prepay  the  principal  balance  of this  Note,  in whole  or in part.  Any such
prepayment  shall be  accompanied  by  accrued  interest  on any  portion of the
principal  of this Note being  prepaid.  Borrower  shall  exercise  its right of
prepayment  by  mailing  a notice to  Lender  of the  amount of this Note  being
prepaid,  30 days in advance of the  intended  prepayment,  and by  delivering a
check  representing the appropriate  consideration  for the prepayment within 45
days after such notice.  No  prepayment  shall be permitted as to any  principal
amount for which Lender has requested  conversion under Section 2 above prior to
the end of the 30-day period following the giving of the notice of prepayment by
Borrower.

      4.    Events of Default.  Each of the following events, if occurring while
any of the principal or interest of this Note remains unpaid,  shall  constitute
an "Event of Default" hereunder:  the Borrower or any of its active subsidiaries
shall  commence,  or there shall be  commenced  against the Borrower or any such
active  subsidiary a case under any applicable  bankruptcy or insolvency laws as
now or hereafter in effect or any successor  thereto,  or the Borrower commences
any other proceeding under any reorganization,  arrangement, adjustment of debt,
relief of debtors, dissolution,  insolvency or liquidation or similar law of any
jurisdiction  whether now or hereafter in effect relating to the Borrower or any
active  subsidiary  thereof or there is  commenced  against the  Borrower or any
active  subsidiary  thereof any such bankruptcy,  insolvency or other proceeding
which remains undismissed for a period of 60 days; or the Borrower or any active
subsidiary thereof is adjudicated  insolvent or bankrupt; or any order of relief
or other order approving any such case or proceeding is


                                        4


entered;   or  the  Borrower  or  any  active  subsidiary  thereof  suffers  any
appointment of any custodian or the like for it or any  substantial  part of its
property which  continues  undischarged  or unstayed for a period of 60 days; or
the Borrower or any active subsidiary thereof makes a general assignment for the
benefit of creditors;  or the Borrower or any active subsidiary thereof shall by
any act or failure to act  expressly  indicate  its consent  to,  approval of or
acquiescence in any of the foregoing;  or any corporate or other action is taken
by the  Borrower or any active  subsidiary  thereof for the purpose of effecting
any of the foregoing.

            Immediately upon the occurrence of an Event of Default,  at Lender's
option, (i) the Maturity Date shall be deemed to have occurred automatically and
(ii) the  entire  principal  amount  of this Note  then  outstanding,  all other
amounts payable by the Borrower hereunder shall automatically  become and be due
and payable, without presentment, demand, protest or any notice of any kind, all
of which are hereby  expressly  waived by the Borrower,  anything  herein to the
contrary notwithstanding.  Upon the occurrence and during the continuation of an
Event of Default,  the Lender  shall have,  in addition to all other  rights and
remedies  under this Note and related  documents,  all other rights and remedies
provided under each applicable  jurisdiction  and other  applicable  laws, which
rights shall be cumulative.

      5.    Representations  of  Borrower.  The  Borrower  hereby represents and
warrants to the Lender as follows:

            (a)   as of the date  hereof  (i)  there are  100,712,038  shares of
Common Stock and 44,000,000  shares of Preferred  Stock issued and  outstanding,
and (ii) the Lender's total aggregate current  liabilities are approximately US$
46,000.00 (the "Liabilities").

            (b)   The proceeds received by the Borrower from this Note shall not
be used to pay any of the Liabilities.

      6.    Representations of Lender. The Lender acknowledges that the Borrower
will  rely  on  the information and on the representations set forth herein, and
hereby represents, warrants and agrees that:

                  (a)   The Lender is an "Accredited Investor",  as that term is
defined under Section 501 (a) of Regulation D under the Act. Lender  understands
and agrees that it is a  condition  to the  conversion  of this Note that Lender
must be an  accredited  investor at the time of the  conversion of this Note, or
that such conversion shall be pursuant to another available exemption.

                  (b)   The Lender has not received any general  solicitation or
general advertising regarding the issuance of this Note.

                  (c)   The Lender has  sufficient  knowledge and  experience in
financial  and business  matters so that he or it is able to evaluate the merits
and risks of this Note as well as substantial experience in previous private and
public   purchases   of   securities.   The  Lender  is  not  relying  upon  any
recommendations or advice in connection with the investment contemplated


                                        5


hereby,  other  than  those  made by  Lender's  own  financial  advisors  and/or
attorneys,  whom Lender has consulted or had the  opportunity to consult with in
connection with the investment contemplated by this Note.

                  (d)   The   Lender  understands  that  an  investment  in  the
Borrower  involves  significant  risk.  The Lender  does not  require  the funds
evidenced by this Note for his  liquidity or other needs,  possesses the ability
to bear the economic risk of holding this Note or the Common Stock issuable upon
conversion thereof indefinitely and can afford a complete loss of its investment
in this Note or such Common Stock.

                  (e)   Prior  to  the  issuance  of  this  Note  and  prior  to
conversion, the Lender has or will have had full opportunity to ask questions of
and  receive   answers  from  the  Borrower  and  its  officers  and  authorized
representatives  regarding  the  terms  and  conditions  of  this  Note  and the
transactions  contemplated  hereby,  as well as the affairs of the  Borrower and
related  matters.  The Lender  confirms  that he does not desire to receive  any
further information.

                  (f)   The  Lender  understands  that  the Conversion Price has
been  arbitrarily  determined and does not necessarily  bear any relationship to
investment criteria such as projected earnings, discounted cash flow, book value
or other measures of value.

                  (g)   The Lender understands that this Note has not been filed
with  or  reviewed  by  the  U.S.   Securities  and  Exchange   Commission  (the
"Commission") nor the securities  department of any state because of the private
or limited nature of this offering as defined by applicable  laws, and that this
Note  and the  Common  Stock  issuable  upon  conversion  thereof  have not been
registered with the Commission under the Act nor with the securities  department
of any state in reliance upon an exemption therefrom for non-public offerings.

                  (h)   The  Lender  represents  and warrants that this Note and
the Common Stock  issuable upon  conversion  thereof are or will be acquired for
investment  purposes  and not  with a view to or for sale or  distribution.  The
Lender  represents  that  there  is  no  contract,  undertaking,   agreement  or
arrangement with any person to sell, transfer or pledge to such person or anyone
else this Note or the Common Stock issuable upon conversion  thereof or any part
thereof,  and the  Lender  has no  present  plans to enter  into such  contract,
undertaking,  agreement or arrangement  and will neither  directly or indirectly
seek to  assign,  transfer  or sell  the same in any way  inconsistent  with the
legend which is being placed on this Note.

      7.    Notices.  Any  and all notices or other communications or deliveries

      8.    Amendments  and  Waivers. Any provision of this Note may be modified
and  compliance  with any provision may be waived by the written  consent of the
Borrower and the Lender.

      9.    Governing  Law.  This  Note  and  the  provisions  hereof  are to be
construed  according  to and are  governed by the laws of the State of New York,

jurisdiction.  Any dispute  arising  hereunder  shall be subject to adjudication
solely in the  federal  and state  courts  of the State of  Wyoming  in New York
County. The Borrower and Lender hereby consent to the exclusive  jurisdiction of
such courts, waiving any claim of inconvenient forum.
