CONVERTIBLE
PROMISSORY NOTE




U.S.
      $1,093,770.60
            March
      8, 2010





FOR VALUE
RECEIVED, Gwenco, Inc., a Kentucky corporation (the “Maker”),
hereby promises to pay to Interstellar Holdings, LLC, or its successors and
assigns (the “Payee”),
at its address at 1446 Redding Road, Fairfield CT, 06824, or to such other
address as the Payee shall provide in writing to the Maker for such purpose, the
principal sum of ONE MILLION NINETY THREE THOUSAND SEVEN HUNDRED SEVENTY AND
60/100 DOLLARS (U.S. $1,093,770.60).




The
entire principal amount hereunder, together with all accrued but unpaid interest
shall be due and payable in full on March 8, 2015 (the “Maturity
Date”), or on such earlier date as such amount may earlier become due and
payable pursuant to the terms hereof or the terms of the Loan
Agreement.  The Maker hereby authorizes the Payee to record, on the
schedule(s) annexed to this Convertible Promissory Note as Exhibit
A (the “Loan
Schedule”), the date and amount of each payment or prepayment of
principal made by the Maker, and of each conversion pursuant to Section 3 below,
and agrees that all such notations shall be conclusive absent manifest error;
provided, however, that the
failure of the Payee to make any such notation shall not affect the Maker’s
obligations hereunder.




1.           Interest
Rate.




(a)           Interest
shall accrue on the unpaid principal amount of this Convertible Promissory Note
(the “Note”)
at the rate of twelve percent (12%) per annum from the Effective Date until the
earlier of (a) the date such unpaid principal amount and all accrued but unpaid
interest hereon are paid in full or (b) the date all such principal amount and
accrued interest are converted into shares (the “Shares”)
of the common stock, $0.0001 par value, of Quest Minerals & Mining Corp.
(the “Parent”),
a Utah corporation and the parent corporation of the Maker (the “Common
Stock”), in accordance with the terms hereof.  Interest
hereunder shall be paid as set forth below or on such earlier date as any
principal amount and accrued interest hereunder are converted in accordance with
the terms hereof.  Interest shall be computed on the basis of a
360-day year for the actual number of days elapsed.




1




(b)           Upon
the occurrence and during the continuation of an Event of Default (and at the
election of the Payee), including, without limitation, if the principal amount
of this Note and all accrued interest are not paid in full on the Maturity Date,
the entire outstanding principal amount hereunder, together with accrued and
unpaid interest, shall bear interest at a per annum rate equal to eight percent
(8%) above the per annum rate otherwise applicable hereunder (the “Default
Rate”).




(c)           In
no event shall the interest rate or rates payable under this Note, plus any
other amounts paid in connection herewith, exceed the highest rate permissible
under any law that a court of competent jurisdiction shall, in a final
determination, deem applicable; provided, however, that notwithstanding anything
to the contrary herein, if any rate or rates of interest or manner of payment
specified herein exceeds the maximum allowable under applicable law, then, as of
the date of this Note, the Maker is and shall be liable only for the payment of
such maximum as allowed by law, and payments received from the Maker in excess
of such legal maximum, whenever received, shall be applied to reduce the
principal balance of this Note to the extent of such excess.




(d)           All
payments made on this Note shall be remitted to the Payee and all such payments
shall be applied to as the Payee elects or as follows:




(i)          first,
to pay any expenses and fees then due to Payee hereunder until paid in
full;




(ii)         second,
to pay interest then due in respect of this Note until paid in
full;




(iii)        third,
to pay principal then due in respect of this Note until paid in
full.




For
purposes of the foregoing, “paid in full” means payment of all amounts owing
under this Note according to the terms thereof, including loan fees, service
fees, professional fees, interest (and specifically including interest accrued
after the commencement of any Insolvency Proceeding), interest at the Default
Rate, interest on interest, and expense reimbursements, whether or not the same
would be or is allowed or disallowed in whole or in part in any Insolvency
Proceeding.




2.           Conversion of Principal and
Interest.




(a)           Subject
to the terms and conditions hereof, the Payee, at its sole option, may deliver
to the Maker a notice in the form attached hereto as Exhibit
B (a “Conversion
Notice”) at any time and from time to time after the date hereof and
prior to the payment in full of the principal amount of and all accrued interest
on this Note (the date of the delivery of a Conversion Notice, a “Conversion
Date”), to convert all or any portion of the outstanding principal amount
of this Note, plus accrued and unpaid interest thereon, into that number of
Shares equal to the quotient obtained by dividing the dollar amount of such
outstanding principal amount of this Note, plus the accrued and unpaid interest
thereon, being converted by the Conversion Price (as defined in Section
17).  Conversions hereunder shall have the effect of lowering the
outstanding principal amount of this Note plus all accrued and unpaid interest
thereunder in an amount equal to the applicable conversion, which shall be
evidenced by entries set forth in the Conversion Notice and the Loan
Schedule.




2




(b)           The
Parent shall at all times reserve and keep available out of its authorized but
unissued shares of Common Stock, solely for the purpose of effecting the
conversion provisions of this Note, such number of Shares as shall from time to
time be sufficient to effect the conversion provisions of this
Note.




(c)           If,
at any time while this Note is outstanding, the Per Share Market Value of a
share of Common Stock falls below $0.0015 for three (3) consecutive Trading
Days, then within thirty (30) calendar days thereafter, the Parent shall effect
a reverse split of its Common Stock as directed by Lender.




3.           Certain Conversion
Limitations.




(a)           The
Payee may not convert any outstanding principal amount of this Note or accrued
and unpaid interest thereon to the extent such conversion would result in the
Payee, together with any affiliate thereof, beneficially owning (as determined
in accordance with Section 13(d) of the Exchange Act (as defined in Section 17)
and the rules promulgated thereunder) in excess of 4.99% of the then-issued and
outstanding shares of Common Stock.  Since the Payee will not be
obligated to report to the Parent the number of shares of Common Stock it may
hold at the time of a conversion hereunder, unless the conversion at issue would
result in the issuance of Shares in excess of 4.99% of the then-outstanding
shares of Common Stock without regard to any other shares which may be
beneficially owned by the Payee or an affiliate thereof, the Payee shall have
the authority and obligation to determine whether and the extent to which the
restriction contained in this Section will limit any particular conversion
hereunder.  The provisions of this Section may be waived by the Payee
upon not less than 61 days’ prior notice to the Maker.




(b)           The
Payee may not convert any outstanding principal amount of this Note or accrued
and unpaid interest thereon to the extent such conversion would require the
Parent to issue shares of Common Stock in excess of Parent’s then-maximum
authorized but unissued shares of Common Stock; provided, however, that Parent
shall use its best efforts to increase its maximum authorized shares of Common
Stock to accommodate such conversion.




3




4.           Deliveries.  Not
later than three Trading Days (as defined in Section 17) after any Conversion
Date (the “Delivery
Date”), the Maker will deliver to the Payee (i) a certificate or
certificates representing the number of Shares being acquired upon the
conversion of the principal amount of this Note and any interest accrued
thereunder being converted pursuant to the Conversion Notice (subject to the
limitations set forth in Section 3 hereof), and (ii) an endorsement by the Maker
of the Loan Schedule acknowledging the remaining outstanding principal amount of
this Note plus all accrued and unpaid interest thereon not converted (an “Endorsement”).  The
Maker’s delivery to the Payee of stock certificates in accordance with clause
(i) above shall be Maker’s conclusive endorsement of the remaining outstanding
principal amount of this Note plus all accrued and unpaid interest thereon not
converted as set forth in the Loan Schedule.




5.           Mandatory Prepayment Upon
Triggering Events. Upon the occurrence of a Triggering Event (as defined
below), the Payee shall have the right (in addition to all other rights it may
have hereunder, under the Loan Agreement or under applicable law), exercisable
at the sole option of the Payee, to require the Maker to prepay all or a portion
of the outstanding principal amount of this Note plus all accrued and unpaid
interest thereon. Such prepayment shall be due and payable within thirty (30)
Trading Days of the date on which the notice for the payment therefor is
provided by the Payee.




A “Triggering
Event” means any one or more of the following events (whatever the reason
and whether it shall be voluntary or involuntary, or effected by operation of
law or pursuant to any judgment, decree or order of any court, or any order,
rule or regulation of any administrative or governmental body):




(i)           an
Event of Default; or




(ii)          the
Maker shall fail for any reason to deliver certificates or an Endorsement to the
Payee prior to the sixtieth (60th) day after a Conversion Date pursuant to and
in accordance with Section 4.




6.           Creation of Security
Interest.




(a)           The
Maker hereby grants to the Payee a first priority (subject only to the Liens
granted to Interstellar Holdings, LLC, a Nevada limited liability company
pursuant to that certain Loan and Security Agreement (the “Loan
Agreement”) of even date herewith among Interstellar Holdings, LLC,
Gwenco, Inc., a Kentucky corporation, Quest Minerals & Mining Corp., a Utah
corporation, and Quest Minerals & Mining, Ltd., a Nevada corporation),
continuing security interest in all of the Maker’s right, title, and interest in
all currently existing and hereafter acquired or arising Collateral in order to
secure prompt repayment of any and all of the Maker’s obligations hereunder
(“Obligations”)  The
Payee’s Liens in and against the Collateral shall attach to all Collateral
without the requirement of any further action on the part of the Maker or the
Payee.  Anything contained in this Convertible Promissory Note to the
contrary notwithstanding, except for Permitted Dispositions (as defined in the
Loan Agreement), the Maker has no authority, express or implied, to dispose of
any item or portion of the Collateral.




4




(b)           In
the event that any Collateral, including proceeds, is evidenced by or consists
of Negotiable Collateral, and if and to the extent that perfection or priority
of Payee’s security interest is dependent on or enhanced by possession, the
Maker, promptly upon the request of the Payee, shall endorse and deliver
physical possession of such Negotiable Collateral to the Payee.




(c)           At
any time after the occurrence and during the continuation of an Event of
Default, the Payee or the Payee’s designee may (a) notify Account Debtors of the
Maker (with concurrent notice to the Maker) that the Accounts, chattel paper, or
General Intangibles have been assigned to the Payee or that the Payee has a
security interest therein, or (b) collect the Accounts, chattel paper, or
General Intangibles directly and charge the collection costs and expenses to the
Maker.  The Maker agrees that it will hold in trust for the Payee, as
the Payee’s trustee, any proceeds of Collateral that it receives and immediately
will deliver said proceeds of Collateral to the Payee in their original form as
received by the Maker.




(d)           At
any time upon the request of the Payee, the Maker shall execute and deliver, or
cause to be executed and delivered, to the Payee any and all security
agreements, pledges, assignments, endorsements of certificates of title,
waivers, access agreements, and all other documents (the “Additional
Documents”) that the Payee may reasonably request to perfect and continue
perfected or better perfect the Payee’s Liens in the Collateral (whether now
owned or hereafter arising or acquired).




(e)           The
Maker hereby irrevocably makes, constitutes, and appoints Payee (and any of
Payee’s officers, employees, or agents designated by Payee) as the Maker’s true
and lawful attorney, with power to (a) if the Maker refuses to, or fails within
five (5) Business Days to execute and deliver any of the documents described in
Section 6(d), sign the name of the Maker on any of the documents described in
Section 6(d), (b) at any time that an Event of Default has occurred and is
continuing, sign the Maker’s name on any invoice or bill of lading relating to
the Collateral, drafts against Account Debtors, or notices to Account Debtors,
(c) send requests for verification of Accounts, (d) endorse the Maker’s name on
any collection item that may come into the Payee’s possession, (e) at any time
that an Event of Default has occurred and is continuing, make, settle, and
adjust all claims under the Maker’s policies of insurance and make all
determinations and decisions with respect to such policies of insurance, and (f)
at any time that an Event of Default has occurred and is continuing, settle and
adjust disputes and claims respecting the Accounts, chattel paper, or General
Intangibles directly with Account Debtors, for amounts and upon terms that the
Payee determines to be reasonable, and the Payee may cause to be executed and
delivered any documents and releases that the Payee determines to be
necessary.  The appointment of the Payee as the Maker’s attorney, and
each and every one of its rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully and finally repaid and
performed and the Payee’s obligations to extend credit hereunder are
terminated.




5




(f)           The
Payee shall, upon reasonable notice to the Maker and during normal business
hours have the right, from time to time hereafter to inspect the Books and to
examine, check, test, and appraise the Collateral.




(g)           The
Maker hereby authorizes the Payee to file one or more financing statements and
fixture filings disclosing the security interest and Lien of the Payee in any or
all of the Collateral without, to the extent permitted by law, the Maker’s
signature thereon.  The Maker hereby irrevocably makes, constitutes
and appoints the Payee the Maker’s attorney in fact with full power and for the
limited purpose to sign in the name of the Maker any documents that in the
Payee’s discretion would be necessary, appropriate or convenient in order to
perfect and maintain perfection of the security interests and Lien granted
hereunder, such power being coupled with an interest and remaining irrevocable
so long as any of the Obligations remain outstanding.




7.           Guaranty.




(a)           Each
Guarantor hereby unconditionally and irrevocably guarantees the punctual payment
when due, whether at stated maturity, by acceleration or otherwise, of all
Obligations of the Maker now or hereafter existing under this Convertible
Promissory Note, whether for principal, interest fees, expenses or otherwise
(such obligations, to the extent not paid by the Maker, being the “Guaranteed
Obligations”), and agrees to pay any and all expenses (including
reasonable counsel fees and expenses) incurred by the Payee in enforcing any
rights under the guaranty set forth in this Section 7.  This is a
guaranty of payment not of collection.




(b)           Each
Guarantor guarantees that the Guaranteed Obligations will be paid strictly in
accordance with the terms of this Convertible Promissory Note, regardless of any
law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of the Payee with respect
thereto.  The obligations of each Guarantor under this Section 7 are
independent of the Guaranteed Obligations, and a separate action or actions may
be brought and prosecuted against each Guarantor to enforce such obligations,
irrespective of whether any action is brought against the Maker or whether the
Maker is joined in any such action or actions.  The liability of each
Guarantor under this Section 7 shall be irrevocable, absolute and unconditional
irrespective of, and each Guarantor hereby irrevocably waives any defenses it
may now or hereafter have in any way relating to, any or all of the
following:




(i)           any
lack of validity or enforceability of this Convertible Promissory Note or any
agreement or instrument relating thereto;




6




(ii)          any
change in the time, manner or place of payment of, or in any other term of, all
or any of the Guaranteed Obligations, or any other amendment or waiver of or any
consent to departure from this Convertible Promissory Note, including, without
limitation, any increase in the Guaranteed Obligations resulting from the
extension of additional credit to the Maker or otherwise;




(iii)         any
taking, exchange, release or non-perfection of any Collateral, or any taking,
release or amendment or waiver of or consent to departure from any other
guaranty, for all or any of the Guaranteed Obligations;




(iv)         any
change, restructuring or termination of the corporate, limited liability company
or partnership structure or existence of the Maker; or




(v)          any
other circumstance (including, without limitation, any statute of limitations)
or any existence of or reliance on any representation by the Payee that might
otherwise constitute a defense available to, or a discharge of, any Guarantor,
the Maker or any other guarantor or surety.




This
Section 7 shall continue to be effective or be reinstated, as the case may be,
if at any time any payment of any of the Guaranteed Obligations is rescinded or
must otherwise be returned by the Payee or any other person or entity, all as
though such payment had not been made.




(c)           Each
Guarantor hereby waives promptness, diligence, notice of acceptance and any
other notice with respect to any of the Guaranteed Obligations and this Section
7 and any requirement that the Payee exhaust any right or take any action
against the Maker or any other person or entity or any
Collateral.  Each Guarantor acknowledges that it will receive direct
and indirect benefits from the financing arrangements contemplated herein and
that the waiver set forth in this Section 7(c) is knowingly made in
contemplation of such benefits.  Each Guarantor hereby waives any
right to revoke this Section 7, and acknowledges that this Section 7 is
continuing in nature and applies to all Guaranteed Obligations, whether existing
now or in the future.




(d)           This
Section 7 is a continuing guaranty and shall (a) remain in full force and effect
until the later of (i) the indefeasible cash payment in full of the Guaranteed
Obligations (other than indemnification obligations as to which no claim has
been made) and all other amounts payable under this Section 7 and (ii) the
Maturity Date, (b) be binding upon each Guarantor, its successors and assigns
and (c) inure to the benefit of and be enforceable by the Payee and its
successors, pledgees, transferees and assigns.  Without limiting the
generality of the foregoing clause (c), the Payee may pledge, assign or
otherwise transfer all or any portion of its rights and obligations under this
Agreement (including, without limitation, all or any portion of loans owing to
it and any note held by it) to any other person or entity, and such other person
or entity shall thereupon become vested with all the benefits in respect thereof
granted the Payee herein or otherwise.




7




(e)           Each
Guarantor will not exercise any rights that it may now or hereafter acquire
against the Maker or any other insider guarantor that arise from the existence,
payment, performance or enforcement of any Guarantor’s obligations under this
Section 7, including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution or indemnification and any right to
participate in any claims or remedy of the Payee against the Maker or any other
insider guarantor or any Collateral, whether or not such claim, remedy or right
arises in equity or under contract, statute or common law, including the right
to take or receive from the Maker or any other insider guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security solely on account of such claim, remedy or right, unless and
until all of the Guaranteed Obligations and all other amounts payable under this
Section 7 shall have been indefeasibly paid in full in cash and the Maturity
Date shall have occurred.  If any amount shall be paid to any
Guarantor in violation of the immediately preceding sentence at any time prior
to the later of the payment in full in cash of the Guaranteed Obligations and
all other amounts payable under this Section 7 and the Maturity Date, such
amount shall be held in trust for the benefit of the Payee and shall forthwith
be paid to the Payee to be credited and applied to the Guaranteed Obligations
and all other amounts payable under this Section 7 whether matured or unmatured,
in accordance with the terms of this Agreement, or to be held as collateral for
any Guaranteed Obligations or other amounts payable under this Section 7
thereafter arising.  If (i) any Guarantor shall make payment to the
Payee of all or any part of the Guaranteed Obligations, (ii) all of the
Guaranteed Obligations and all other amounts payable under this Section 7 shall
be indefeasibly paid in full in cash, and (iii) the Maturity Date shall have
occurred, the Payee will, at such Guarantor’s request and expense, execute and
deliver to such Guarantor appropriate documents, without recourse and without
representation or warranty necessary to evidence the transfer by subrogation to
such Guarantor of an interest in the Guaranteed Obligations resulting from such
payment by such Guarantor.

9.           The Payee’s Rights and
Remedies.




(a)           Rights and
Remedies.  Upon the occurrence, and during the continuation, of
an Event of Default, the Payee may do any one or more of the following, all of
which are authorized by the Maker:




(i)           Declare
all Obligations, whether evidenced by this Convertible Promissory Note, or
otherwise, immediately due and payable;




(ii)          Cease
advancing money or extending credit to or for the benefit of the Maker under
this Convertible Promissory Note or under any other agreement between the Maker
and the Payee;




(iii)         Terminate
this Convertible Promissory Note as to any future liability or obligation of the
Payee, but without affecting any of the Payee’s Liens in the Collateral and
without affecting the Obligations;




(iv)      
  Settle or adjust disputes and claims directly with Account Debtors
for amounts and upon terms which the Payee considers advisable;




(v)        
 Without notice to or demand upon the Maker, make such payments and do such
acts as the Payee considers necessary or reasonable to protect its security
interests in the Collateral.  The Maker agrees to assemble the
Collateral if the Payee so requires, and to make the Collateral available to the
Payee at a place that the Payee may designate.  The Maker authorizes
the Payee to enter the premises where the Collateral is located, to take and
maintain possession of the Collateral, or any party of it, and to pay, purchase,
contest, or compromise any Lien that in the Payee’s determination appears to
conflict with the Payee’s Liens and to pay all expenses incurred in connection
therewith.  With respect to the Maker’s owned or leased premises, the
Maker hereby grants the Payee a license to enter into possession of such
premises and to occupy the same, without charge, in order to exercise any of
Payee’s rights or remedies provided herein, at law, in equity, or
otherwise;




(vi)        
Without notice to the Maker (such notice being expressly waived), and without
constituting a retention of any collateral in satisfaction of an obligation
(within the meaning of the Code), set off and apply to the Obligations any and
all (i) balances and deposits of the Maker held by the Payee, or (ii)
indebtedness at any time owing to or for the credit or the account of the Maker
held by the Payee;




11




(vii)       Hold,
as cash collateral, any and all balances and deposits of the Maker held by the

etc.  All payments of principal and interest shall be made
without setoff, deduction or counterclaim.  No delay or failure on the

partial or single exercise of its options, powers or rights shall constitute a

of the Payee of any of its options, powers or rights shall constitute a waiver
of any other option, power or right.  The Maker hereby waives demand,
protest, notice of protest, notice of default or dishonor, notice of payment and
