  PROMISSORY
NOTE
  $2,000,000
              February
      29, 2008
   BUCKEYE
VENTURES, INC., a Nevada corporation (the “Company”), for value received, hereby
promises to pay Timothy E. Gallagher (the “Holder”) the principal amount of Two
Million Dollars ($2,000,000), together with accrued interest thereon at the rate
of seven percent (7.00%) per annum (computed on the basis of a 365-day year)
from the date hereof.  Interest shall be payable quarterly in arrears
on the first day of each calendar quarter commencing on April 1,
2008.  The principal amount hereof and all accrued and unpaid interest
shall be due and payable on February 28, 2010 (the “Maturity
Date”).  This Promissory Note (this “Note”) is being issued pursuant
to that certain Agreement and Plan of Merger dated as of February 29, 2008 by
and among the Company, GHA Acquisition Corp., Gallagher’s Heating & Air
Conditioning, Inc., a California corporation (the “Operating Company”), and the
Holder (the “Merger Agreement”) and is subject to the terms and conditions set
forth therein.  Capitalized terms used and not otherwise defined in
this Note shall have the meanings ascribed to such terms in the Merger
Agreement.
  In the
event the Company fails to make any required quarterly interest payment within
ten (10) days of the quarterly due date for such payment, the Company shall be
required to make an additional payment to the Holder in the amount equal to two
percent (2%) of the portion of the interest payment that remains unpaid after
such ten (10) day grace period as a penalty.
  The
Company shall have the right to prepay this Note in whole or in part without
penalty at any time and from time to time with or without prior notice;
provided, however, that if the Company prepays this Note in whole or in part the
Company shall provide the Holder with warrants or other rights that will provide
the Holder with right to acquire such Common Stock of the Company that the
Holder was precluded from acquiring due to such prepayment for the same price,
same periods and on the same basis as if such prepayment had not been
made.  Except as expressly provided in this Note, payments of
principal and interest on this Note shall be made in lawful money of the United
States of America paid by check to the Holder delivered to the Holder at its
address identified in the Merger Agreement, or such other location as the holder
of this Note shall have designated by written notice to the Company; provided, however, that at
the election of the Company, all or any part of the principal and interest due
hereunder may be paid by wire transfer to an account designated by the
Holder.
  If any
payment hereunder becomes due and payable on a Saturday, Sunday, or legal
holiday under the laws of the State of California, the due date thereof shall be
extended to the next succeeding business day, and interest shall be payable
thereon during such extension at the rate specified above.
  1
  In no
contingency or event whatsoever shall interest charged hereunder, however such
interest may be characterized or computed, exceed the highest rate permissible
under any law which a court of competent jurisdiction shall, in a final
determination, deem applicable hereto.  In the event that such a court
determines that the Holder has received interest hereunder in excess of the
highest rate applicable hereto, the Holder shall promptly apply to such excess
amount to the unpaid principal balance or, to the extent no such balance exists,
refund such excess interest to the Company.
  The
Holder may at any time on or after the date of this Note (the “Conversion Start
Date”) and prior to the Maturity Date convert up to the initial principal amount
of this Note (the “Convertible Portion”) or any portion of the Convertible
Portion in increments of not less than $10,000 (unless such amount is the only
portion of the Convertible Portion then remaining outstanding under this Note in
which event the conversion of the remaining principal amount included in the
Convertible Portion shall be permitted) into fully paid and nonassessable shares
of the Common Stock, par value $.001 per share, of the Company (the "Common
Stock"), on the basis of one share of such stock for each $0.20 in principal
amount of this Note if converted on or prior to January 31, 2009 and one share
of such stock for each $0.25 in principal amount of this Note if converted on or
after February 1, 2009 (the "Conversion Price").  Such conversion
shall be effected by the surrender of this Note at the principal office of the
Company (or such other office or agency of the Company as the Company may
designate by notice in writing to the Holder) at any time during usual business
hours, together with notice in writing that the Holder wishes to convert a
portion of this Note, which notice shall also state the name (with address) and
denominations in which the certificate(s) for Common Stock shall be issued and
shall include instructions for delivery thereof.  Such conversion
shall be deemed to have been effected as of the close of business on the date on
which this Note shall have been surrendered and such notice shall have been
received, and at such time (the "Conversion Date") the rights of the Holder with
respect to the principal amount of the Note converted shall cease and the person
in whose name any certificate(s) for Common Stock are to be issued upon such
conversion shall be deemed to have become the holder of record of the shares of
Common Stock represented by such certificate(s).  As soon as
practicable after the Conversion Date, the Company shall deliver to, or as
directed by, the Holder, certificates representing the number of shares of
Common Stock issuable by reason of such conversion registered in such name and
such denomination or denominations as the Holder shall have specified, together
with cash as provided below in respect of any fraction of a share of such stock
otherwise issuable upon such conversion.  The Company shall make
payment to the Holder of accrued interest to the date of conversion on the
portion of the Note converted at the time and in the manner provided for the
payment of interest of this Note.  In each case of conversion, the
Company shall either (i) endorse on this Note the date and amount of this Note
so converted, and such amount shall be deemed no longer outstanding and promptly
return this Note to the Holder, or (ii) promptly execute and deliver a new Note
to the Holder in the principal amount equal to the remaining principal amount of
this Note.  The Company covenants that all shares of Common Stock
which shall be so issuable shall, when issued, be duly and validly issued, fully
paid and nonassessable.
  In the
event the Company shall at any time subdivide (by any stock split, stock
dividend or otherwise) its outstanding Common Stock into a greater number of
shares of such stock, the Conversion Price shall be proportionately
decreased.  Conversely, in the event the outstanding shares of Common
Stock shall at any time be combined into a smaller number of shares (by reverse
stock split or otherwise), the Conversion Price shall be proportionately
increased.  In the case of any stock dividend described in this
paragraph, the adjustment to be made shall be made as of the time immediately
after the close of business on the record date for the determination of holders
of any class of securities entitled to receive such dividend; provided, however,
that if such record date shall have been fixed and such dividend shall not have
been fully paid on the date fixed, such adjustment shall be cancelled as of the
close of business on such record date and, thereafter, the Conversion Price
shall be adjusted pursuant to this paragraph as of the time of actual payment of
such dividend.  In the
  2
  case of
any subdivision (other than a stock dividend) or combination described in this
paragraph, the adjustment to be made pursuant hereto shall be made as of the
close of business on the date immediately prior to the date upon which such
corporate action becomes effective.  Notwithstanding the foregoing,
the Company shall not be required to give effect to any adjustment to the
Conversion Price if the amount of such adjustment would be less than $.01, but
any such adjustment shall be carried forward and adjustment with respect thereto
shall be made at the time of and together with any subsequent adjustment which,
together with such amount and any other amount or amounts so carried forward,
causes a cumulative net adjustment of $.01 or more.
  If any
capital reorganization or reclassification of the capital stock of the Company
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of an issuance of Common Stock by
dividend or other distribution or by reason of a subdivision or combination), or
any consolidation or merger of the Company with or into another corporation, or
any sale of all or substantially all of the Company's property and assets to any
person, firm or corporation (collectively, any "Organic Change") shall be
effected in such a way that holders of Common Stock shall be entitled to receive
(either directly or upon subsequent liquidation) stock, securities or assets
with respect to or in exchange for Common Stock, then, as a condition to such
Organic Change, lawful and adequate provision shall be made whereby the Holder
shall thereafter have the right to acquire and receive upon the basis and upon
the terms and conditions specified herein and in lieu of the shares of Common
Stock of the Company immediately theretofore acquirable and receivable (directly
or upon subsequent conversion, assuming unrestricted convertibility) upon the
conversion of this Note, such shares of stock, securities or assets as may be
issued or payable with respect to or in exchange for a number of outstanding
shares of Common Stock equal to the number of shares of Common Stock immediately
theretofore acquirable and receivable (directly or upon subsequent conversion,
assuming unrestricted convertibility) upon conversion of this Note had such
Organic Change not taken place (except that the terms of the parenthetical
provisions at the end of the next sentence shall be applied in determining the
number of shares of Common Stock immediately theretofore acquirable and
receivable).  In any such case, appropriate provision shall be made
with respect to the Holder's rights and interests to the end that the provisions
contained in this Note (including without limitation provisions for adjustments
of the number of shares of Common Stock acquirable and receivable upon the
exercise of the conversion rights granted herein) shall thereafter be applicable
in relation to any shares of stock, securities or assets thereafter deliverable
upon the conversion of this Note (including, in the case of any such
consolidation, merger or sale in which the successor corporation or purchasing
entity is other than the Company, an immediate adjustment in the number of
shares of Common Stock acquirable and receivable upon conversion of this
Note).  In the event of a merger or consolidation of the Company with
or into another corporation or the sale of all or substantially all of the
Company's property and assets to another corporation as a result of which a
number of shares of common stock of the surviving or purchasing corporation
greater or lesser than the number of shares of Common Stock of the Company
outstanding immediately prior to such merger, consolidation or sale are issuable
to holders of Common Stock, the aggregate number of shares of Common Stock into
which this Note was convertible in effect immediately prior to such merger,
consolidation or sale shall be adjusted (pursuant to the preceding paragraph) as
though there were a subdivision or combination of the outstanding shares of
Common Stock.  The provisions of this paragraph shall similarly apply
to successive Organic Changes.
  3
  Promptly
upon any adjustment in the number of shares of Common Stock acquirable and
receivable upon conversion of this Note or any adjustment or readjustment in the
Conversion Price, the Company shall send written notice to the Holder, which
notice shall set forth in reasonable detail the method of calculation and the
facts upon which such calculation is based.  The Company shall, upon
written request at any time of any holder of this Note, furnish or cause to be
furnished to such holder a similar certificate setting forth (i) such
adjustments and readjustments, (ii) the Conversion Price then in effect, and
(iii) the number of shares of Common Stock and the amount, if any, of other
property which then would be received upon the conversion of this
Note.  The Company may retain a firm of independent public accountants
of recognized standing which may be the firm regularly retained by the Company
to make any computation required under this Note and a certificate signed by
such firm shall be conclusive evidence of the correctness of any computation
made under this Section.
  The
Company shall not be required to issue any fractional shares of Common Stock
upon any conversion of this Note.  If any fraction of a share of
Common Stock except for the provisions of this paragraph would be issuable upon
conversion of this Note, the Company may elect not to convert such portion of
the Note or in lieu of issuing such fractional share pay an amount in cash equal
to the then current fair market thereof as determined by the Company in good
faith.
  To the
extent applicable, the Company may withhold any present or future income, stamp
or other taxes, levies, imposts, duties, charges, fees, deductions or
withholdings, now or hereafter imposed, levied, collected, withheld or assessed
by any governmental authority from any amounts payable to the Holder hereunder
and the Company shall send to the Holder notice showing payment
thereof.  The Company will not be responsible for any income tax of
the Holder for interest due on the Note, or stamp duty or other tax due on
conversion of the Note.  Nothing contained in this Note shall be
construed as conferring upon the Holder the right to receive any dividend or
other distribution as a stockholder or to vote or to consent or to receive
notice as a stockholder in respect of the meetings of stockholders for the
election of directors of the Company or any other matter.
  If any of
the following conditions or events (each an “Event of Default” and collectively,
the “Events of Default”) shall occur and be continuing:
  (a) if the
Company shall default in the payment of any principal on this Note when the same
becomes due and payable, whether at maturity or otherwise, and such payment
shall not have been made within fifteen (15) days after written notice of
default shall have been received by the Company from the Holder; or
  (b) if the
Company shall default in the payment of any interest on the Note when the same
becomes due and payable and such default shall continue more than thirty (30)
days after written notice of default shall have been received by the Company
from the Holder; or
  (c) if the
Company shall make an assignment for the benefit of creditors, or shall admit in
writing its inability to pay its debts as they become due, or shall file a
voluntary petition in bankruptcy, or shall be adjudicated as bankrupt or
insolvent, or shall file any petition or answer seeking for itself any
reorganization, arrangement, composition, readjustment, liquidation, dissolution
or similar relief under any present or future statute, law or regulation, or
shall file any answer admitting or not contesting the material allegations of a
petition filed against the Company in any such proceeding, or shall seek or
consent to or acquiesce in the appointment of any custodian, trustee, receiver
or liquidator of the Company or of all or any substantial part of the properties
of the Company, or if the Company or its directors or majority stockholders (or
such greater number as may be required to effect such action) shall take any
action looking to the dissolution or liquidation of the Company; or
  4
  (d) if,
within sixty (60) days after the commencement of an involuntary bankruptcy
proceeding or other action against the Company seeking any reorganization,
arrangement, composition, readjustment, liquidation, dissolution or similar
relief under any present or future statute, law or regulation, such action shall
not have been dismissed or all orders or proceedings thereunder affecting the
operations or the business of the Company stayed, or if the stay of any such
order or proceeding shall thereafter be set aside, or if, within sixty (60) days
after the appointment without the consent or acquiescence of the Company of any
custodian, trustee, receiver or liquidator of the Company or of all or any
substantial part of the properties of the Company, such appointments shall not
have been vacated;
  then the
Holder hereof may at any time (unless all Events of Default shall theretofore
have been remedied or cured) at its option, by written notice to the Company,
declare this Note to be due and payable, whereupon this Note shall forthwith
mature and become due and payable, together with interest accrued and unpaid
hereon, without presentment, demand, protest or notice, all of which are hereby
waived.
  This
Note is a nonrecourse note and is secured solely by security interests and liens
in the shares of stock and assets of the Operating Company granted in the
Security Documents.  The Company shall be liable upon the indebtedness
evidenced by this Note, for all sums to accrue or to become payable hereon and
for performance of any covenants contained in this Note or in the Security
Documents to the extent, but only to the extent, of the security granted to the
Holder pursuant to the Security Documents.  No attachment, execution
or other writ or process shall be sought, issued or levied against the Company
or upon any assets, properties or funds of the Company other than the properties
and assets pledged pursuant to the Security Documents.  In the event
of any enforcement or foreclosure of such security interests, no judgment of any
deficiency upon such indebtedness, sums and amounts shall be sought or obtained
by the Holder against the Company.
  Notwithstanding
anything to the contrary contained in this Note, in the event that the Company,
GHA Acquisition Corp. or the Operating Company (each, an “Indemnified Party”) is
(or, pending resolution of a disputed claim, may be) entitled to receive any
amounts from the Stockholder (an “Indemnifying Party”) under the Merger
Agreement or under any of the other documents executed or to be executed in
connection with the Merger Agreement, including without limitation any amounts
owed under the indemnification provisions of Article 11 of the Merger Agreement,
the Company may take any one or more of the following actions (and such actions
shall not result in an Event of Default under this Agreement):
  (i) offset
and deduct from any amounts to be paid to the Holder of this Note (or that may
be converted by the Holder) any amounts owed by any Indemnifying Party to any
Indemnified Party under the Merger Agreement or any other agreement or document
executed in connection with the Merger Agreement; or
  (ii) pending
resolution of any claim, withhold from the amounts to be paid to the Holder of
this Note (or that may be converted by the Holder) any amounts which may be owed
by any Indemnifying Party to any Indemnified Party under the Merger Agreement or
any other agreement or document executed in connection with the Merger
Agreement;
  5
  In either
case, neither such amount nor any interest on such amount shall be required to
be paid by the Company to Holder (or converted), provided, however, that if
within thirty (30) days the Holder notifies the Company that it disputes the
amounts so offset, deducted or withheld, then if and to the extent the Holder
prevails with respect to such dispute amounted the Holder shall be entitled to
any interest required to be paid pursuant to this Note with respect to the
disputed amount and not paid as a result of the operation of this
sentence.
  THIS NOTE
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS (AND NOT
THE CONFLICTS OF LAW PROVISIONS) OF THE STATE OF CALIFORNIA.
  All
notices delivered pursuant to the terms hereof shall be deemed to have been duly
given when given in accordance with the terms of the Merger
Agreement.
  Whenever
in this Note reference is made to the Company or the Holder, such reference
shall be deemed to include their respective heirs, legal representatives,
successors and assigns; provided, however, that the Holder may not transfer this
Note or any portion of this Note or any of its rights under this Note or any
portion hereof, including without limitation to the Common Stock or other
securities that may be issuable or issued with respect to the Convertible
Portion of this Note, without the consent of the Company or, with respect to
such Common Stock, as expressly permitted pursuant to the terms of the Transfer
Restriction Agreement.
   IN WITNESS WHEREOF, the
undersigned has caused this Note to be executed by its duly authorized officer
on the date first above written.
