Exhibit 10.3

SUNTRUST                                                 Unconditional Guaranty

                                IMPORTANT NOTICE
THIS INSTRUMENT CONTAINS A CONFESSION OF JUDGMENT PROVISION WHICH CONSTITUTES A
WAIVER OF IMPORTANT RIGHTS YOU MAY HAVE AS A BORROWER/GUARANTOR AND ALLOWS THE
CREDITOR TO OBTAIN A JUDGMENT AGAINST YOU WITHOUT ANY FURTHER NOTICE.

This guaranty of RGC Resources, Inc. ("Guarantor") dated November 25, 2005,
provides:

Whereas, Bluefield Gas Company (herein, whether one or more, the "Borrower")
desires to transact business with and to obtain creditor a continuation of
credit from SunTrust Bank, its present and future affiliates and their
successors and assigns (collectively, "SunTrust"); and

Whereas, SunTrust is unwilling to extend or continue credit to Borrower unless
it receives a guaranty from the undersigned Guarantor with respect to the
Obligations, as defined below, of Borrower to SunTrust;

Now, Therefore, in consideration of the premises and of other good and valuable
consideration and in order to induce SunTrust from time to time, in its sole
discretion, to extend or continue credit to or enter into other transactions
with Borrower, Guarantor absolutely and unconditionally guarantees to SunTrust
performance and payment when due, whether by acceleration or otherwise, of any
and all Obligations of Borrower to SunTrust, together with all interest and
charges related thereto, and all attorneys' fees (in the amount of 15% of the
principal and interest guaranteed hereby if this guaranty is governed by the
laws of Georgia), and all costs and expenses of collection incurred by SunTrust
in enforcing the Obligations or this guaranty, subject to the provisions
contained herein.

1.       The term "Obligations" or "Obligation" as used herein shall include,
         without limitation, any and all liabilities, obligations, agreements
         and undertakings of Borrower to SunTrust in any amount, whether now
         existing or hereafter arising (including those owed by Borrower to
         others and acquired by SunTrust through purchase, assignment or
         otherwise), however created, evidenced or arising, whether
         individually or jointly with others, and whether absolute or
         contingent, direct or indirect, as maker, endorser, guarantor, surety
         or otherwise, liquidated or unliquidated, matured or unmatured,
         whether or not secured by collateral, and including, without
         limitation, (a) all obligations to perform or forbear from performing
         any acts, (b) all overdrafts on deposits or accounts maintained by
         Borrower with SunTrust, and (C) the liabilities, obligations,
         agreements and undertakings of Borrower to SunTrust pursuant to any
         foreign exchange contract or any interest rate hedge agreement or
         other derivative transaction agreement or pursuant to any application
         or other agreement requesting SunTrust to issue any letter of credit
         including, without limitation, the obligation of Borrower to reimburse
         SunTrust for all amounts funded by SunTrust pursuant to any such
         letter of credit, and (d) all costs of collection including attorneys'
         fees, whether such collection occurs prior to, during, or after any
         bankruptcy proceedings filed by or against Borrower.

         The amount of the undersigned's liability under this guaranty shall be
         unlimited.

2.       This guaranty is a continuing guaranty, shall remain in force
         irrespective of any interruptions in the business relations of Borrower
         with SunTrust and shall apply to and guarantee any balance which shall
         remain due by Borrower to SunTrust; provided, however, that Guarantor
         may, by written notice delivered personally to an officer of SunTrust
         or received by registered mail by an officer of SunTrust, terminate
         this guaranty with respect to all Obligations of the Borrower incurred
         or contracted by the Borrower or acquired by SunTrust after the date on
         which the notice is actually received by such officer. Such termination
         shall not be applicable to any Obligation incurred prior to the receipt
         of such notice by SunTrust.

3.       SunTrust may at any time and from time to time, in the exercise of its
         sole discretion, either before or after default by Borrower or
         revocation or termination of this guaranty, without the consent of or
         notice to Guarantor, and without incurring responsibility to Guarantor,
         or releasing or impairing the liability of Guarantor, or any security
         available to SunTrust, upon or without any terms or conditions:

         a.       Change the manner, place, or terms of payment (including
                  payment amounts and rate of interest) and/or change or extend
                  the time of payment, renew or alter any Obligation, any
                  collateral or security therefore, or any Obligation incurred
                  directly or indirectly in respect thereof, and this guaranty
                  shall apply to the Obligations as so changed, extended,
                  renewed or altered;






         b.       Sell, exchange, release, surrender, realize upon or otherwise
                  deal with in any manner and in any order any collateral or
                  security at any time held by or available to SunTrust for any
                  Obligation, or for any obligations of Guarantor or any person
                  secondarily or otherwise liable for any of the Obligations;
                  SunTrust shall have full authority to adjust, compromise and
                  receive less than the amount due upon any such collateral;

         c.       Exercise or refrain from exercising any rights against
                  Borrower, Guarantor or others, or otherwise act or refrain
                  from acting;

         d.       Release, compromise, or agree not to sue, in whole or in part,
                  Borrower, Guarantor or any other party obligated on any of the
                  Obligations;

         e.       Apply any sums received by it from any source to any
                  Obligation or Obligations, in such order of application as Sun
                  Trust may elect, regardless of what Obligation or Obligations
                  remain unpaid. All payments shall be conclusively presumed to
                  have been made by Borrower and no payment shall operate to
                  reduce the obligation of a Guarantor unless, at the time such
                  payments are made, written notice is delivered to an officer
                  of SunTrust that such payments are made by a Guarantor in
                  reduction of Guarantor's liability hereunder, and such
                  payments are actually made by Guarantor; and

         f.       Fail to set off and release, in whole or in part, any balance
                  of any deposit account or credit on its books in favor of
                  Borrower, or any other person liable for any of the
                  Obligations, and may extend further credit in any manner to
                  Borrower, and generally deal with Borrower or any security or
                  other person liable for any of the Obligations as SunTrust, in
                  its sole discretion, may see fit.

4.       As security for the payment of the Obligations and the obligation of
         Guarantor hereunder, Guarantor hereby assigns and grants a security
         interest to SunTrust in (a) all property of Guarantor in or coming into
         the possession, control or custody of SunTrust, or in which SunTrust
         has or hereafter acquires a lien, security interest, or other right;
         and (b) any existing or hereafter created lien or security interest in
         favor of Guarantor in any property of Borrower.

5.       Guarantor waives notice of acceptance of the guaranty and notice,
         including notice of default, on any Obligation to which it may apply,
         and waives notice of presentment and demand for payment of any of the
         Obligations, suit or other action taken by SunTrust against, and any
         other notice to, Guarantor or to any other party liable for the
         Obligations. Guarantor waives all defenses, offsets and counterclaims
         which Guarantor may at any time have to any claim of SunTrust against
         Borrower. Except for any limitation which is specified above with
         respect to the amount of the maximum liability of Guarantor, this is
         an unconditional guaranty, and the liability of Guarantor to SunTrust
         shall not be terminated or in any way limited by reason or as the
         result of anything set forth or contained in any writing evidencing
         all or any part of the Obligations, nor shall it be limited to a
         proportionate part of the total of the Obligations. This is a guaranty
         of payment and not of collection and Guarantor waives any right to
         require that any action be brought against Borrower or any other
         person or to require that resort be had to any security or to any
         balance of any deposit account or credit on the books of SunTrust in
         favor of Borrower or any other person and agrees that SunTrust is not
         responsible for the validity, perfection, recordation or
         enforceability of any collateral or security for the Obligations.

6.       Guarantor hereby ratifies, confirms, and adopts all the terms,
         conditions, agreements and stipulations of all notes and other
         evidences of the Obligations heretofore or hereafter executed. Without
         in any way limiting the generality of the foregoing, Guarantor waives
         and renounces any and all homestead exemption right Guarantor may have
         under or by virtue of the Constitution or laws of any state, or the
         United States, as against the obligation hereby created, provided
         however, that such waiver shall not apply to any obligation created
         hereunder which arises from any of the Obligations that are consumer
         credit transactions; and Guarantor does hereby transfer, convey and
         assign, and direct any Trustee in Bankruptcy or receiver to deliver
         to SunTrust, a sufficient amount of property or money in any homestead
         exemption that may be allowed to Guarantor to pay any Obligation in
         full and all costs of collection. Guarantor waives and renounces any
         defense to any of the Obligations which may be available to or could
         be asserted by Borrower, except for payment.

7.       Guarantor subordinates all indebtedness of Borrower owing to Guarantor,
         whether now existing or hereafter arising, to the Obligations.
         Guarantor further agrees that it shall not be subrogated to, and will
         not enforce on its behalf, any right of action which SunTrust may have
         against Borrower until every






         Obligation shall have been paid in full. SunTrust shall have the right,
         immediately and without further action by it, to set off against any
         obligation of Guarantor to SunTrust, all money owed by SunTrust in any
         capacity to Guarantor, whether or not due.

8.       A subsequent guaranty by Guarantor shall not be deemed to be in lieu of
         or to supersede or terminate this guaranty but shall be construed as an
         additional or supplementary guaranty unless otherwise expressly
         provided therein; and in the event Guarantor, or any other guarantor,
         has given to SunTrust a previous guaranty or guaranties, this guaranty
         shall be construed to be an additional or supplemental guaranty, and
         not to be in lieu thereof or to terminate such previous guaranty or
         guaranties unless expressly so provided herein.

9.       This guaranty shall be binding on the Guarantor, notwithstanding the
         failure of any further contemplated guarantor(s) to execute similar
         instruments and notwithstanding the fact that the signature of one or
         more other parties guaranteeing the Obligations or any other existing
         or future signature shall be forged or unauthorized. The revocation of
         this guaranty in the manner permitted hereunder by Guarantor or any
         other party guaranteeing the Obligation, or the release by SunTrust of
         any one or more parties guaranteeing the Obligations, or the death of
         Borrower or Guarantor or any other party guaranteeing the Obligations,
         shall not affect or limit the liability of Guarantor, and SunTrust
         shall be under no duty to notify Guarantor of any such revocation,
         release or death.

10.      Guarantor warrants to SunTrust that Guarantor has adequate means to
         obtain from Borrower on a continuing basis information concerning the
         financial condition of Borrower and that Guarantor is not relying on
         SunTrust to provide such information either now or in the future.
         Guarantor waives all errors and omissions in connection with SunTrust's
         administration of the Obligations except behavior which amounts to
         gross negligence or willful misconduct.

11.      No invalidity, irregularity or unenforceability of all or any part of
         the Obligations or of any collateral or security therefor shall affect,
         impair, or be a defense to this guaranty, and this guaranty is a
         primary obligation of Guarantor.

12.      The term "Guarantor" as used herein shall mean the undersigned
         Guarantor and if the undersigned is a partnership or limited liability
         company, the obligations and liability of Guarantor shall remain in
         full force and applicable notwithstanding any changes in the identity
         of the parties comprising the partnership or limited liability company,
         and the term "Guarantor" shall include any altered or successor
         partnership or limited liability company, and the predecessor
         partnership or limited liability company, and their partners or
         member/managers shall not thereby be released from any obligation or
         liability.

13.      No delay on the part of SunTrust in exercising any rights hereunder or
         failure to exercise the same shall operate as a waiver of such rights;
         no notice to or demand on Guarantor shall be deemed to be a waiver of
         the obligation of Guarantor or of the right of SunTrust to take further
         action without notice or demand as provided herein; nor in any event
         shall any modification or waiver of the provisions of this guaranty be
         effective unless in writing signed by SunTrust nor shall any such
         waiver be applicable except in the specific instance for which given.

14.      Guarantor agrees to provide to SunTrust updated financial information,
         including, but not limited to, tax returns and current financial
         statements in form satisfactory to SunTrust, as well as additional
         information, reports or schedules (financial or otherwise), all as
         SunTrust may from time to time request.

15.      Notwithstanding the fact that the Obligations of Borrower may have been
         paid in full and this guaranty may have been returned to Guarantor, the
         obligations of Guarantor hereunder shall continue in full force and
         effect with respect to any amounts that SunTrust may ever be required
         to repay under any Bankruptcy or insolvency laws.

16.      This guaranty shall not be construed to impose any obligation on
         SunTrust to extend or continue any credit at any time.

17.      Each reference herein to SunTrust shall be deemed to include its
         successors and assigns, in whose favor the provisions of this guaranty
         shall also inure. Each reference herein to Guarantor shall be deemed to
         include heirs, executors, administrators, legal representatives,
         successors and assigns, all of whom shall be bound by the provisions of
         this guaranty.






18.      Guarantor agrees that certain material events and occurrences relating
         to this guaranty bear a reasonable relationship to the laws of
         Virginia. This guaranty shall be governed by the laws of Virginia and,
         unless applicable law provides otherwise, in the event of any legal
         proceeding arising out of or related to this guaranty, the Guarantor
         consents to the jurisdiction and venue of any court located in
         Virginia. To the extent that any provision in this guaranty is
         inconsistent with applicable law, SunTrust will comply with applicable
         law.

19.      Guarantor hereby duly constitutes and appoints R. Grayson Goldsmith and
         William H. Tuttle as its true and lawful attorney-in-fact in its name,
         place and stead, and upon the occurrence of an event of default, to
         confess judgment against it in the Circuit Court for the Roanoke,
         Virginia, upon this guaranty and all amounts owed hereunder, including
         all costs of collection, attorneys' fees and court costs, hereby
         ratifying and confirming the acts of the attorney-in-fact as if done by
         itself, expressly waiving benefit of any homestead or other exemption
         laws.

WAIVER OF JURY TRIAL. GUARANTOR AND SUNTRUST HEREBY KNOWINGLY, VOLUNTARILY,
INTENTIONALLY, AND IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, THE RIGHT EITHER OF THEM MAY HAVE TO A TRIAL BY JURY IN RESPECT
TO ANY LITIGATION, WHETHER IN CONTRACT OR TORT, AT LAW OR IN EQUITY, BASED
HEREON OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS GUARANTY AND ANY
OTHER DOCUMENT OR INSTRUMENT CONTEMPLATED TO BE EXECUTED IN CONJUNCTION WITH
THIS GUARANTY, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY HERETO. THIS PROVISION IS A MATERIAL
INDUCEMENT FOR SUNTRUST ENTERING INTO OR ACCEPTING THIS GUARANTY. FURTHER,
GUARANTOR HEREBY CERTIFIES THAT NO REPRESENTATIVE OR AGENT OF SUNTRUST, NOR
SUNTRUST'S COUNSEL, HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUNTRUST WOULD
NOT, IN THE EVENT OF SUCH LITIGATION, SEEK TO ENFORCE THIS WAIVER OF RIGHT TO
JURY TRIAL PROVISION.

The undersigned Guarantor has read, understands and agrees to the provisions of
this guaranty and has executed the same voluntarily, with full authority and
with the intent to be legally bound by its terms, conditions and obligations.
