BEACON ENERGY HOLDINGS, INC.

 

CONVERTIBLE SUBORDINATED NOTE

	$__________	February 4, 2011

 

FOR VALUE RECEIVED,
BEACON ENERGY HOLDINGS, INC., a Delaware corporation, which will effective upon the Closing (as defined below) change its name
to EQM Technologies & Energy, Inc. (the “Debtor”), promises to pay to the order of __________________ (the “Holder”),
or its registered assigns, the principal amount of __________________ DOLLARS ($________), in such coin or currency of the United
States of America as at the time of payment shall be legal tender for the payment of public or private debts, together with interest
as set forth herein (the “Loan”).

 

Effective upon the
closing (the “Closing”) of that certain Agreement and Plan of Merger, dated January 25, 2011, among the Debtor, Beacon
Acquisition, Inc. and Environmental Quality Management, Inc. (the “Merger Agreement”), this Note shall replace that
certain note issued by the Debtor to the Holder (the “Original Note”), and the Original Note shall be cancelled, in
accordance with that certain Beacon Noteholder Consent attached as Exhibit A hereto (the “Consent”). As provided
in the Consent, subject to and effective upon the Closing, the holders of at least two-thirds (2/3) of the principal amount of
the Original Notes approved the replacement and cancellation of the Original Notes and released and forever discharged the Debtor
from its obligation to pay any unpaid principal and accrued but unpaid interest payable under the Original Notes, and from all
claims, demands, actions, damages, penalties, expenses and costs of any kind that the holders, their successors or assigns ever
had, now have or hereafter may have against the Debtor relating to the Original Notes.

 

    	 

    	 

    

 

1.          Payment
of Interest and Principal on the Loan. All unpaid principal, together with any then accrued and unpaid interest and any other
amounts payable hereunder, shall be due and payable on the third anniversary of the date of the Closing (the “Maturity Date”).
If any payment hereunder becomes due and payable on a Saturday, Sunday or legal holiday under the laws of the United States of
America or the State of New York, or both, the due date thereof shall be extended to the next business day and interest shall be
payable for any principal so extended for the period of such extension. Payments of principal and interest are to be made at the
address provided herein for the Holder (or at such other place as the Holder shall have notified the Debtor in writing at least
five (5) days before such payment is due) or by wire transfer pursuant to the Holder’s written instructions. Unless Debtor
is otherwise notified by Holder in writing, all payments due hereunder shall be made to Holder at _______________________________.

 

2.          Ranking.
Payment of all or any portion of the outstanding principal amount of this Note and all interest hereon, including prepayments,
shall be pari passu in right of payment and in all other respects to the other Notes. Except with the consent of all Note holders,
Debtor shall not prepay any holder of any of the Notes, except for prepayment in full of all of the Notes pursuant to Section
7 hereof. In the event the Holder receives payments in excess of its pro rata share of the Debtor’s payments to the holders
of all of the Notes, then the Holder shall hold in trust all such excess payments for the benefit of the holders of the other Notes
and shall pay such amounts held in trust to such other holders pro rata upon demand by such holders.

 

3.          Interest.
(a) Interest shall accrue on the unpaid principal balance of this Note at the rate of ten percent (10%) per annum. Interest shall
be calculated from and include the date of the Closing, and shall be calculated on an actual/360-day basis.

 

(b)          Notwithstanding
anything to the contrary contained herein, in no event shall this or any other provision herein permit the collection of any interest
which would be usurious under applicable law. If under any circumstances, whether by reason of advancement or acceleration of the
maturity of the unpaid principal balance hereof or otherwise, the aggregate amounts paid under this Note shall include amounts
which by law are deemed interest and which would exceed the maximum rate permitted by law, Debtor stipulates that payment and collection
of such excess amounts shall have been and will be deemed to have been the result of a mistake on the part of both Holder and Debtor
or the holder of this Note, and the party receiving such excess payments shall promptly credit such excess (only to the extent
such payments are in excess of the maximum rate) against the unpaid principal balance hereof and any portion of such excess payments
not capable of being so credited shall be refunded to Debtor.

 

    	2

    	 

    

 

4.          Security.
This Note, as well as the other Notes, shall be secured by the lien and security interest on Beacon Energy (Texas) Corp.’s
real property located at 3102 Windmill Road, Cleburne, Texas, and the building, equipment, fixtures, and other personal property
located thereon (the “Property”), as set forth in that certain Deed of Trust and Security Agreement, dated April 7,
2009 (the “Deed of Trust”), subject to the terms of the Subordination Agreement (including, without limitation, the
right of Senior Lender to file a mortgage and obtain a first lien on the Property in accordance with the Subordination Agreement).

 

5.          Conversion
at the Option of the Holder.

 

(a)          At
any time while any portion of the principal or interest of this Note is outstanding, the Holder may give Debtor written notice
of its intention to convert (the “Voluntary Conversion”) all or any portion of the outstanding principal and/or accrued
but unpaid interest on this Note into such number of shares of Debtor’s common stock, par value $0.001 per share (the “Common
Stock”), equal to the amount to be converted divided by the Conversion Price in effect at such time. Upon receipt of the
Holder’s written notice, Debtor shall cause certificates representing those shares to be delivered to the Holder within five
(5) business days of Debtor’s receipt of such notice. The person or persons entitled to receive the shares of Common Stock
issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common
Stock on the date the applicable conversion notice is given.

 

(b)          The
“Conversion Price” initially shall be $1.3899 and shall be subject to adjustment as set forth below. The Conversion
Price shall be adjusted proportionally for any subsequent stock dividend or split, stock combination or other similar recapitalization,
reclassification or reorganization of or affecting the Common Stock; provided, however, that the Conversion Price
shall not be adjusted as a result of the 1 for 5 reverse split of the Common Stock to take place prior to the Closing, as contemplated
under the Merger Agreement.

 

(c)          In
case of a Change of Control (as defined below), instead of receiving shares of Common Stock upon conversion of this Note, the Holder
shall have the right thereafter to receive the kind and amount of shares of stock and other securities, cash and property that
the Holder would have owned or have been entitled to receive immediately after such Change of Control had the same portion of this
Note been converted immediately prior to the effective date of such Change of Control and, in any such case, if necessary, appropriate
adjustment shall be made in the application of the provisions set forth in this Section 5 with respect to the rights and
interests thereafter of the Holder, to the end that the provisions set forth in this Section 5 shall thereafter correspondingly
be made applicable, as nearly as may reasonably be, in relation to any shares of stock and other securities, cash and property
thereafter deliverable in connection with this Note. The provisions of this subsection shall similarly apply to successive Changes
of Control.

 

    	3

    	 

    

 

“Change
of Control” means that Debtor shall, directly or indirectly, in one or more related transactions, (i) consolidate or merge
with or into (whether or not Debtor is the surviving corporation) another person, (ii) sell, assign, transfer, convey or otherwise
dispose of all or substantially all of the properties or assets of Debtor to another person, (iii) allow another person to make
a purchase, tender or exchange offer that is accepted by the holders of more than 50% of the outstanding shares of Common Stock
(not including any shares of Common Stock held by the person or persons making or party to, or associated or affiliated with the
persons making or party to, such purchase, tender or exchange offer), or (iv) consummate a stock purchase agreement or other business
combination (including, without limitation, a reorganization, recapitalization or spin-off) with another person whereby such other
person acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other
person or other persons making or party to, or associated or affiliated with the other persons making or party to, such stock purchase
agreement or other business combination); provided, however, that Debtor’s entry into the Merger Agreement
and the consummation of the transactions contemplated thereby shall not be deemed to constitute a Change of Control.

 

(d)          Debtor
shall not issue fractional shares of Common Stock upon conversion of this Note; rather, Debtor shall round up the number of shares
issued to the nearest whole number.

 

(e)          In
the event of an adjustment to the Conversion Price, Debtor shall promptly deliver to the Holder a certificate, signed by its Chief
Financial Officer, setting forth the new Conversion Price and a calculation in reasonable detail of the adjustment to the Conversion
Price.

 

(f)          Debtor
shall pay any and all taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of this
Note; provided that Debtor shall not be required to pay any tax that may be payable in respect of any issuance of Common Stock
to any person other than the Holder or with respect to any income tax due by the Holder with respect to such Common Stock.

 

6.          Events
of Default. (a) Acceleration. Upon the occurrence of any of the following events (herein called “Events of Default”):

 

(i)          The
Debtor shall fail to make full and timely payment of principal of or interest on this Note or any of the other Notes when due and
such failure continues for a period of five consecutive days;

 

(ii)         The
sale of all or substantially all of the assets of the Debtor or any of its material subsidiaries, or the Debtor shall merge or
consolidate with any other entity, as a result of which the stockholders of the Debtor own less than a majority of the equity interests
in the resulting entity, other than pursuant to the terms of the Merger Agreement and the transactions contemplated thereby;

 

(iii)        (A)
The Debtor or any of its material subsidiaries shall commence any proceeding or other action relating to it in bankruptcy or seek
reorganization, arrangement, readjustment of its debts, receivership, dissolution, liquidation, winding-up, composition or any
other relief under any bankruptcy law, or under any other insolvency, reorganization, liquidation, dissolution, arrangement, composition,
readjustment of debt or any other similar act or law, of any jurisdiction, domestic or foreign, now or hereafter existing; or (B)
the Debtor or any of its material subsidiaries shall admit the material allegations of any petition or pleading in connection with
any such proceeding; or (C) the Debtor or any of its material subsidiaries shall apply for, or consent or acquiesce to, the appointment
of a receiver, conservator, trustee or similar officer for it or for all or a substantial part of its property; or (D) the Debtor
or any of its material subsidiaries shall make a general assignment for the benefit of creditors;

 

    	4

    	 

    

 

(iv)        (A)
The commencement of any proceedings or the taking of any other action against the Debtor or any of its material subsidiaries in
bankruptcy or seeking reorganization, arrangement, readjustment of its debts, liquidation, dissolution, arrangement, composition,
or any other relief under any bankruptcy law or any other similar act or law of any jurisdiction, domestic or foreign, now or hereafter
existing; or (B) the appointment of a receiver, conservator, trustee or similar officer for the Debtor or any of its material subsidiaries
for any of its property; or (C) the issuance of a warrant of attachment, execution or similar process against any of the property
of the Debtor or any of its material subsidiaries, and the continuance of any such events for 60 days undismissed, unbonded or
undischarged;

 

(v)         The
Debtor breaches any of its representations and warranties made under the Deed of Trust, which breach shall continue uncured for
thirty (30) calendar days after notice thereof to the Debtor; provided, however, that any breach under the Deed of Trust occurring
on or before December 31, 2011 shall be not deemed to be an Event of Default;

 

(vi)        The
Debtor shall fail to comply with any of its obligations under this Note (other than repayment) or the Deed of Trust, which failure
shall continue uncured for thirty (30) calendar days after notice thereof to the Debtor; provided, however, that any such failure
to comply with the Deed of Trust occurring on or before December 31, 2011 shall not be deemed to be an Event of Default; or

 

(vii)       The
Debtor’s Common Stock shall not be quoted on the OTCBB or listed on the pink sheets, NASDAQ or any other national securities
exchange for a period of more than three (3) consecutive business days.

 

then, and in any such event, the Holder, at the Holder’s
option and without written notice to the Debtor, may declare the entire principal amount of this Note then outstanding together
with accrued unpaid interest thereon immediately due and payable, and the same shall forthwith become immediately due and payable
without presentment, demand, protest, or other notice of any kind, all of which are expressly waived. The Events of Default listed
herein are solely for the purpose of protecting the interests of the Holder of this Note. If the Note is not paid in full upon
acceleration, as required above, interest shall accrue on the outstanding principal of and interest on this Note from the date
of the Event of Default up to and including the date of payment at a rate equal to the lesser of fourteen percent (14%) per annum
or the maximum interest rate permitted by applicable law. To remove any doubt, for purposes of this Section 6, Beacon Energy
Corp. and Beacon Energy (Texas) Corp. shall be deemed “material subsidiaries” of the Debtor.

 

    	5

    	 

    

 

(b)          Non-Waiver
and Other Remedies. No course of dealing or delay on the part of the Holder of this Note in exercising any right hereunder
shall operate as a waiver or otherwise prejudice the right of the Holder of this Note. No remedy conferred in this Note or the
Deed of Trust is intended to be exclusive of any other remedy, and each and every such remedy shall be cumulative and shall be
in addition to every other remedy conferred herein or now or hereafter existing at law or equity or by statute or otherwise.

 

(c)          Collection
Costs; Attorney’s Fees. In the case of an Event of Default, if this Note is turned over to an attorney for collection,

expenses incurred by the Holder in connection with such collection efforts, which amounts may, at the Holder’s option, be
added to the principal hereof.

 

7.            Prepayments.
This Note may be prepaid by the Debtor in whole, at any time, or in part, from time to time, without penalty or premium, upon 10
business days prior written notice provided that at the time of any such prepayment all accrued and unpaid interest shall be paid

and either retroactively or prospectively) without the prior written consent of the party against whom such amendment, modification,
or waiver is sought to be enforced; provided, however, that with respect to the Holder, amendments, modifications
and waivers must be consented to by at least two-thirds (2/3) of the principal amount of the Notes then outstanding (the “Requisite
Approval”) and upon such approval, such amendment, modification and waiver shall be binding on the Holder. All of the terms
and provisions of this Note shall be applicable to and binding upon each and every maker, Holder, endorser, surety, guarantor and
all other persons who are or may become liable for the payment hereof and their respective successors and assigns. The exercise
of any remedies under this Note may be made, only with the Requisite Approval.

Debtor shall at any time or from time to time after the date hereof issue or sell any additional shares of Common Stock, or other
equity or debt securities convertible into Common Stock, in exchange for consideration in an amount per share of Common Stock (on
an as converted basis, if applicable) less than the Conversion Price at the time such securities are issued or sold, then the Conversion
Price immediately prior to such issue or sale shall be reduced to a price determined by dividing:

 

(i)          an
amount equal to the sum of (A) the number of shares of Common Stock outstanding immediately prior to such issue or sale multiplied
by the then existing Conversion Price, plus (B) the consideration, if any, received by Debtor upon such issue or sale; by

 

(ii)         the
total number of shares of Common Stock outstanding immediately after such issue or sale.

 

(d)          In
case of a Change of Control (as defined below), instead of receiving shares of Common Stock upon conversion of this Note, the Holder
shall have the right thereafter to receive the kind and amount of shares of stock and other securities, cash and property that
the Holder would have owned or have been entitled to receive immediately after such Change of Control had the same portion of this
Note been converted immediately prior to the effective date of such Change of Control and, in any such case, if necessary, appropriate
adjustment shall be made in the application of the provisions set forth in this Section 4 with respect to the rights and
interests thereafter of the Holder, to the end that the provisions set forth in this Section 4 shall thereafter correspondingly
be made applicable, as nearly as may reasonably be, in relation to any shares of stock and other securities, cash and property
thereafter deliverable in connection with this Note. The provisions of this subsection shall similarly apply to successive Changes
of Control.

 

“Change
of Control” means that Debtor shall, directly or indirectly, in one or more related transactions, (i) consolidate or merge
with or into (whether or not Debtor is the surviving corporation) another person, (ii) sell, assign, transfer, convey or otherwise
dispose of all or substantially all of the properties or assets of Debtor to another person, (iii) allow another person to make
a purchase, tender or exchange offer that is accepted by the holders of more than 50% of the outstanding shares of Common Stock
(not including any shares of Common Stock held by the person or persons making or party to, or associated or affiliated with the
persons making or party to, such purchase, tender or exchange offer), or (iv) consummate a stock purchase agreement or other business
combination (including, without limitation, a reorganization, recapitalization or spin-off) with another person whereby such other
person acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other
person or other persons making or party to, or associated or affiliated with the other persons making or party to, such stock purchase
agreement or other business combination).

(e)          Debtor
shall not issue fractional shares of Common Stock upon conversion of this Note; rather, Debtor shall round up the number of shares
issued to the nearest whole number.

 

(f)          In
the event of an adjustment to the Conversion Price, Debtor shall promptly deliver to the Holder a certificate, signed by its Chief
Financial Officer, setting forth the new Conversion Price and a calculation in reasonable detail of the adjustment to the Conversion
Price.

 

(g)          Debtor
shall pay any and all taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of this
Note; provided that Debtor shall not be required to pay any tax that may be payable in respect of any issuance of Common Stock
to any person other than the Holder or with respect to any income tax due by the Holder with respect to such Common Stock.

 

5.          Conversion
at the Option of the Debtor. At any time after the one-year anniversary of the date hereof, if and only if the Common Stock
has traded at an average price per share above two (2) times the Conversion Price for sixty (60) consecutive days, then in lieu
of any cash payments, Debtor may, in full satisfaction of this Note, issue to the Holder (the “Maturity Date Conversion”)
a certificate representing such number of shares of Common Stock as is equal to the quotient obtained by dividing (x) the entire
principal amount of this Note then outstanding, plus all accrued but unpaid interest thereon, by (y) the Conversion Price in effect
at such time. The applicable provisions of Section 4 shall apply with equal force to the Maturity Date Conversion.

 

6.          Events
of Default. (a) Acceleration. Upon the occurrence of any of the following events (herein called “Events of Default”):

 

(i)          The
Debtor shall fail to make full and timely payment of principal of or interest on this Note or any of the other Notes when due and
such failure continues for a period of five (5) consecutive days;

 

(ii)         (A)
The Debtor or any of its material subsidiaries shall commence any proceeding or other action relating to it in bankruptcy or seek
reorganization, arrangement, readjustment of its debts, receivership, dissolution, liquidation, winding-up, composition or any
other relief under any bankruptcy law, or under any other insolvency, reorganization, liquidation, dissolution, arrangement, composition,
readjustment of debt or any other similar act or law, of any jurisdiction, domestic or foreign, now or hereafter existing; or (B)
the Debtor or any of its material subsidiaries shall admit the material allegations of any petition or pleading in connection with
any such proceeding; or (C) the Debtor or any of its material subsidiaries shall apply for, or consent or acquiesce to, the appointment
of a receiver, conservator, trustee or similar officer for it or for all or a substantial part of its property; or (D) the Debtor
or any of its material subsidiaries shall make a general assignment for the benefit of creditors;

 

    	4

    	 

    

 

(iii)        (A)
The commencement of any proceedings or the taking of any other action against the Debtor or any of its material subsidiaries in
bankruptcy or seeking reorganization, arrangement, readjustment of its debts, liquidation, dissolution, arrangement, composition,
or any other relief under any bankruptcy law or any other similar act or law of any jurisdiction, domestic or foreign, now or hereafter
existing; or (B) the appointment of a receiver, conservator, trustee or similar officer for the Debtor or any of its material subsidiaries
for any of its property; or (C) the issuance of a warrant of attachment, execution or similar process against any of the property
of the Debtor or any of its material subsidiaries, and the continuance of any such events for 60 days undismissed, unbonded or
undischarged;

 

(iv)         The
Debtor breaches any of its representations and warranties made under that certain Convertible Note Purchase Agreement, dated as
of the date hereof (the “Note Purchase Agreement”), by and between the Debtor and the Holder; or

 

(v)          The
Debtor shall fail to comply with any of its obligations under this Note (other than repayment) or the Note Purchase Agreement,
which failure shall continue uncured for thirty (30) calendar days after notice thereof to the Debtor.

 

then, and in any such event, the Holder,
at the Holder’s option and without written notice to the Debtor, may declare the entire principal amount of this Note then
outstanding together with accrued unpaid interest thereon immediately due and payable, and the same shall forthwith become immediately
due and payable without presentment, demand, protest, or other notice of any kind, all of which are expressly waived. The Events
of Default listed herein are solely for the purpose of protecting the interests of the Holder of this Note. If the Note is not
paid in full upon acceleration, as required above, interest shall accrue on the outstanding principal of and interest on this Note
from the date of the Event of Default up to and including the date of payment at a rate equal to the lesser of twelve percent (12%)
per annum or the maximum interest rate permitted by applicable law. To remove any doubt, for purposes of this Section 6,
Environmental Quality Management, Inc. and Beacon Energy (Texas) Corp. shall be deemed “material subsidiaries” of the
Debtor.

 

(b)          Non-Waiver
and Other Remedies. No course of dealing or delay on the part of the Holder of this Note in exercising any right hereunder
shall operate as a waiver or otherwise prejudice the right of the Holder of this Note. No remedy conferred in this Note or the
Note Purchase Agreement is intended to be exclusive of any other remedy, and each and every such remedy shall be cumulative and
shall be in addition to every other remedy conferred herein or now or hereafter existing at law or equity or by statute or otherwise.

 

    	5

    	 

    

 

(c)          Collection
Costs; Attorney’s Fees. In the case of an Event of Default, if this Note is turned over to an attorney for collection,
the Debtor agrees to pay all reasonable costs of collection, including reasonable attorney’s fees and expenses and all out-of-pocket
expenses incurred by the Holder in connection with such collection efforts, which amounts may, at the Holder’s option, be
added to the principal hereof.

 

7.          Cancellation.
Upon full satisfaction of the Debtor’s obligations hereunder, the Holder shall promptly deliver or cause to be delivered
to the Debtor this Note for cancellation.

 

8.          Amendment;
Waiver. This Note may not be amended or modified or the provisions hereof waived (either generally or in a particular instance
and either retroactively or prospectively) without the prior written consent of the party against whom such amendment, modification,
or waiver is sought to be enforced; provided, however, that with respect to the Holder, amendments, modifications
and waivers must be consented to by at least two-thirds (2/3) of the principal amount of the Notes then outstanding (the “Requisite
Approval”) and upon such approval, such amendment, modification and waiver shall be binding on the Holder. All of the terms
and provisions of this Note shall be applicable to and binding upon each and every maker, Holder, endorser, surety, guarantor and
all other persons who are or may become liable for the payment hereof and their respective successors and assigns. The exercise
of any remedies under this Note may be made, only with the Requisite Approval.

 

9.          Lost

Note or any Note exchanged for it, and (in the case of loss, theft or destruction) of indemnity reasonably satisfactory to it,
and upon surrender and cancellation of such Note, if mutilated, the Debtor will make and deliver in lieu of such Note a new Note
of like tenor and unpaid principal amount and dated as of the original date of the Note.
