                              MERGER AGREEMENT AND

                             PLAN OF REORGANIZATION

            This MERGER AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement")
is made and entered into as of February 22, 2006, by and among UNITED HERITAGE
CORPORATION, a Utah corporation ("United") and LOTHIAN OIL INC., a Delaware
corporation ("Lothian"). In the event the parties mutually agree in writing
prior to the Effective Time (as defined below) to structure this merger as a
reverse triangular merger, rather than a direct merger, a wholly-owned
subsidiary of United (a "Merger Sub") shall become party to this Agreement and
this Agreement shall be amended as appropriate. Capitalized terms used and not
otherwise defined herein have the meanings set forth in Article X.

                                    RECITALS

            WHEREAS, the respective Boards of Directors of each of United and
Lothian believe it is in the best interests of United and Lothian and their
respective stockholders that Lothian merge with and into United (the "Merger")
and, in furtherance thereof, have approved the Merger. Upon mutual consent from
the respective Boards of Directors of each of United and Lothian prior to the
Effective Time, set forth in a writing signed by each of United and Lothian, the
Merger may be restructured as a reverse triangular merger, as contemplated by
the first paragraph hereof;

            WHEREAS, the Boards of Directors of each of United and Lothian have
approved the Merger and this Agreement and the transactions contemplated hereby;

            WHEREAS, pursuant to the Merger, among other things, and subject to
the terms and conditions of this Agreement, (i) all of the shares of common
stock of Lothian which are issued and outstanding immediately prior to the
Effective Time of the Merger shall be converted into the right to receive shares
of United's Common Stock, par value $0.001 ("United Common Stock"), (ii) all of
the shares of preferred stock of Lothian which are issued and outstanding
immediately prior to the Effective Time of the Merger shall be converted into
the right to receive shares of United's Preferred, par value $0.0001 ("United
Preferred Stock"); (iii) all Lothian Options then outstanding (whether vested or
unvested) shall be converted into options to purchase United Common Stock and
(iv) all Lothian Warrants then outstanding shall be converted into warrants to
purchase shares of United Capital Stock, on the terms and subject to the
conditions set forth herein;

            WHEREAS, United and Lothian intend that the Merger shall constitute
a reorganization within the meaning of Section 368(a) of the Code, and in
furtherance thereof intend that this agreement shall be a "Plan of
Reorganization" within the meaning of Sections 354(a) and 361(a) of the Code;
and

            WHEREAS, Lothian and United desire to make certain representations,
warranties, covenants and agreements in connection with the Merger.

            NOW, THEREFORE, in consideration of the covenants, promises,
representations and warranties set forth herein, and for other good and valuable
consideration (the receipt and sufficiency of which are hereby acknowledged by
the parties), and intending to be legally bound hereby, the parties agree as
follows:
<PAGE>

                                    ARTICLE I
                                   THE MERGER

         1.1 The Merger. At the Effective Time subject to and upon the terms and
conditions of this Agreement and the applicable provisions of the Utah Law, and
the DGCL, Lothian shall be merged with and into United, the separate existence
of Lothian shall cease, and United shall continue as the surviving corporation
of the Merger. United is sometimes referred to herein as the "Surviving
Corporation".

         1.2 Effective Time. Unless this Agreement is earlier terminated
pursuant to Section 8.1, the closing and consummation of the Merger (the
"Closing") will take place as promptly as practicable, following satisfaction or
waiver of the conditions set forth in Article V, at the offices of Markowitz &
Roshco LLP, unless another place or time is agreed to by United and Lothian. The
date upon which the Closing actually occurs is herein referred to as the
"Closing Date". On the Closing Date, the parties hereto shall cause the Merger
to be consummated by filing the articles of merger in substantially the form
attached hereto as Exhibit A (the "Utah Articles of Merger") and a certificate
of merger in substantially the form attached hereto as Exhibit B (the "Delaware
Certificate of Merger"), in each case in accordance with the relevant provisions
of applicable Law (the time of acceptance by the Secretary of State of the State
of Delaware of such filing, or such later time agreed to by the parties and set
forth in the Delaware Certificate of Merger, being referred to herein as the
"Effective Time").

         1.3 Effect of the Merger on Constituent Corporations. At the Effective
Time, the effect of the Merger shall be as provided in the applicable provisions
of the DGCL and the Utah Law. Without limiting the generality of the foregoing,
and subject thereto, at the Effective Time, all the property, rights,
privileges, powers and franchises of Lothian shall vest in the Surviving
Corporation, and all debts, liabilities, obligations, restrictions, disabilities
and duties of Lothian shall become the debts, liabilities, obligations,
restrictions, disabilities and duties of the Surviving Corporation.

         1.4 Articles of Incorporation and Bylaws of Surviving Corporation.

             (a) At the Effective Time: (i) the Articles of Incorporation of
United shall be amended to change the name of United to "Lothian Oil Inc.", and
(ii) the board of directors of United shall adopt and direct United to file with
the Utah Secretary of State a Certificate of Designation, Preferences and Rights
of Series A Preferred Stock in the form attached hereto as Exhibit D and a
Certificate of Designation, Preferences and Rights of Series B Preferred Stock
in the form attached hereto as Exhibit E (collectively, the "Series A and B
Certificates"), such that the Articles of Incorporation of United, as amended
and in effect immediately prior to the Effective Time, and as amended at the
Effective Time (including the Series A and B Certificates), shall be the
Articles of Incorporation of the Surviving Corporation from and after the
Effective Time until thereafter amended as provided by Law and such Articles of
Incorporation and the Bylaws of the Surviving Corporation.

             (b) The Bylaws of United, as in effect immediately prior to the
Effective Time, shall be the Bylaws of the Surviving Corporation until
thereafter amended as provided by such Bylaws, the Articles of Incorporation of
the Surviving Corporation and applicable Law.

         1.5 Directors and officers of Surviving Corporation. The directors of
Surviving Corporation at, and immediately after, the Effective Time shall be
Kenneth Levy and C. Scott Wilson (the "Existing Directors"), and Bruce Ransom,
Thomas Kelly, Raoul J. Baxter, Larry W. Wilton and Mike Raleigh (the "Lothian
Designees"), each to hold office in accordance with the Articles of
Incorporation and Bylaws of the Surviving Corporation. If any Lothian Designee
cannot or will not serve as a director of the Surviving Corporation, Lothian may
designate a replacement Lothian Designee, provided such replacement is
reasonably acceptable to the Existing Directors. The officers of Surviving
Corporation at, and immediately after, the Effective Time shall be as mutually
agreed to by Lothian and United, except that it is agreed that C. Scott Wilson
shall be Chief Executive Officer and President and Kenneth Levy shall be Chief
Financial Officer.

         1.6 Consideration To Be Issued; Effect On Outstanding Securities of
Lothian. On the terms and subject to the conditions of this Agreement, as of the
Effective Time, by virtue of the Merger and without any action on the part of
United or Lothian or any holder of any Lothian security, all of the following
shall occur:

             (a)  Conversion of Lothian Capital Stock. At the Effective Time,
(i) each share of Lothian Common Stock that is issued and outstanding
immediately prior thereto (other than any Dissenting Shares (as provided in
Section 1.7)) will be canceled and extinguished and will be converted
automatically into the right to receive that number of shares of United Common
Stock that is equal to the Exchange Ratio, rounded down to the nearest whole
share of United Common Stock, (ii) each share of Lothian Series A Preferred
Stock issued and outstanding immediately prior thereto will be canceled and
extinguished and will be converted automatically into the right to receive that
number of shares of United Series A Preferred Stock that is equal to the
Exchange Ratio, rounded down to the nearest whole share of United Series A
Preferred Stock; and (iii) each share of Lothian Series B Preferred Stock issued
and outstanding immediately prior thereto will be canceled and extinguished and
will be converted automatically into the right to receive that number of shares
of United Series B Preferred Stock that is equal to the Exchange Ratio, rounded
down to the nearest whole share of United Series B Preferred Stock.

             (b)  Cancellation of Lothian-Owned United Common Stock and United
Warrants. At the Effective Time, 1,093,333 shares of United Common Stock and all
United Warrants owned by Lothian or any Subsidiary of Lothian immediately prior
thereto shall be automatically canceled and extinguished without any conversion
thereof and without any further action on the part of United or Lothian.
Following the cancellation of 1,093,333 shares of United Common Stock owned by
Lothian, 2,666,666 shares of United common stock shall remain issued and
outstanding in the name of Lothian, which shares shall continue to be held as
collateral security for the payment of certain obligations of Lothian under a
promissory note dated October 6, 2005 (the "Promissory Note") pursuant to a
Stock Pledge Agreement dated as of October 6, 2005 (the "Stock Pledge
Agreement"). As the 2,666,666 shares of United common stock held as collateral
security for Lothian's obligations under the Promissory Note are released from
the lien of the Stock Pledge Agreement, each such released share shall be
automatically canceled and extinguished without any conversion thereof and
without any further action on the part of United or Lothian. In the event of a
default in the payment of the Promissory Note, the shares of United common stock
then held as collateral security for Lothian's obligations under the Promissory
Note shall be dealt with in the manner proscribed by the Stock Pledge Agreement
and shall be canceled and extinguished only upon the release of such shares from
the lien imposed by the Stock Pledge Agreement, if at all..

             (c)  Lothian Options and Lothian Stock Plan. At the Effective Time
all unexpired and unexercised Lothian Options then outstanding, whether vested
or unvested, shall be assumed by United in accordance with provisions described
below.

                                       3

                  (i)    At the Effective Time, each unexpired and unexercised
Lothian Option including without limitation each unexpired and unexercised
Lothian Option issued pursuant to the Lothian Oil Inc. Stock Incentive Plan
adopted on September 1, 2005 (the "Lothian Stock Plan") which is then
outstanding, whether or not exercisable and whether or not vested, shall by
virtue of the Merger, be assumed by United together with the Lothian Stock Plan
and converted into an option to purchase United Common Stock (a "United Option")
as provided herein and in such manner that (i) United is "assuming a stock
option in a transaction to which Section 424(a) applies" within the meaning of
Section 424 of the Code, or (ii) such transaction, to the extent that Section
424 of the Code does not apply to any such Lothian Options, would be a
transaction within Section 424 of the Code. Each Lothian Option so assumed by
United under this Agreement shall continue to have, and be subject to, the same
terms and conditions as were applicable to such Lothian Option immediately prior
to the Effective Time (including, without limitation, any repurchase rights
(other than rights of refusal) or vesting provisions), provided that (A) such
Lothian Option shall be exercisable for that number of whole shares of United
Common Stock equal to the product of the number of shares of Lothian Capital
Stock that were issuable upon exercise in full of such Lothian Option
immediately prior to the Effective Time (without regard to vesting) multiplied
by the Exchange Ratio (rounded down to the nearest whole number of shares of
United Common Stock) and (B) the per share exercise price for the shares of
United Common Stock issuable upon exercise of such assumed Lothian Option shall
be equal to the quotient determined by dividing the exercise price per share of
Lothian Capital Stock at which such Lothian Option was exercisable immediately
prior to the Effective Time by the Exchange Ratio (rounded up to the nearest
whole cent). United shall, at all times from and after the Effective Time,
reserve, keep and make available for issuance shares of United Common Stock that
are issuable upon the exercise in full of all United Options resulting from the
assumption and conversion of Lothian Options in accordance with this Section and
shall, as promptly as practicable after the Effective Time, issue to each holder
of a Lothian Option that is outstanding immediately prior to the Effective Time
a document evidencing the foregoing assumption of such Lothian Option by United
and the conversion of such Lothian Option into an United Option as provided
herein.

                  (ii)   It is the intention of the parties that Lothian Options
assumed by United and converted into United Options pursuant hereto shall
qualify following the Effective Time as incentive stock options as defined in
Section 422 of the Code to the same extent Lothian Options qualified as
incentive stock options immediately prior to the Effective Time and the
provisions of this Section 1.6(c) shall be applied consistent with this intent.

                  (iii)  At the Effective Time, United shall assume Lothian's
obligations, and shall be assigned Lothian's repurchase rights and purchase
options entered into pursuant to the Lothian Stock Plan. Any and all
restrictions on Lothian Common Stock issued pursuant to Lothian Stock Plan or
such other agreements which do not lapse in accordance with their terms (as such
terms were in effect on the date of this Agreement) and which are not rights of
refusal shall continue in full force and effect until such restrictions lapse
pursuant to the terms of such agreements, and any repurchase rights or purchase
options which Lothian has with respect to the Lothian Stock Plan shall also
continue in full force and effect. The United Options issued in exchange for the
Lothian Options pursuant to this Section 1.6(c) shall be registered under the
Securities Act pursuant to an effective registration statement on Form S-8, as
provided in more detail in Section 4.10.

             (d)  Lothian Warrants. At the Effective Time each unexpired and
unexercised Lothian Warrant that is then outstanding, whether or not exercisable
and whether or not vested, shall be assumed by United and converted into a
warrant to purchase shares of United Common Stock or United Preferred Stock, as
the case may be (a "United Warrant") as provided herein. Each Lothian Warrant so
assumed by United under this Agreement shall continue to have, and be subject
to, the same terms and conditions as were applicable to such Lothian Warrant
immediately prior to the Effective Time, provided that (A) such Lothian Warrant
shall be exercisable for that number of whole shares of United Capital Stock
equal to the product of the number of shares of Lothian Capital Stock that were
issuable upon exercise in full of such Lothian Warrant immediately prior to the
Effective Time (without regard to vesting) multiplied by the Exchange Ratio
(rounded down to the nearest whole number of shares of United Common Stock) and
(B) the per share exercise price for the shares of United Capital Stock issuable
upon exercise of such assumed Lothian Warrant shall be equal to the quotient
determined by dividing the exercise price per share of Lothian Capital Stock at
which such Lothian Warrant was exercisable immediately prior to the Effective
Time by the Exchange Ratio (rounded up to the nearest whole cent). United shall,
at all times from and after the Effective Time, reserve, keep and make available
for issuance all shares of United Capital Stock that are issuable upon the
exercise in full of all United Warrants resulting from the assumption and
conversion of Lothian Warrants in accordance with this section and shall, as
promptly as practicable after the Effective Time, issue to each holder of a
Lothian Warrant that is outstanding immediately prior to the Effective Time a
document evidencing the foregoing assumption of such Lothian Warrant by United
and the conversion of such Lothian Warrant into a United Warrant as provided
herein.

                                       4
<PAGE>

             (e)  Exchange Ratio. The "Exchange Ratio" shall be .60606. The
Exchange Ratio shall be equitably adjusted to reflect fully the effect of any
stock split, reverse split, stock combination, stock dividend (including any
dividend or distribution of securities convertible into United Common Stock or
Lothian Capital Stock), reorganization, reclassification, recapitalization or
other like change with respect to United Common Stock or Lothian Capital Stock
occurring after the date hereof and prior to the Effective Time. No adjustment
shall be made to the Exchange Ratio as a result of any cancellation of any
Lothian Equity Security or any consideration (in any form whatsoever) received
by Lothian as a result of any exercise, conversion or exchange of Lothian Equity
Securities, after the Effective Time.

             (f)  Fractional Shares. No fraction of a share of United Capital
Stock will be issued in the Merger, but in lieu thereof, each holder of shares
of Lothian Capital Stock who would otherwise be entitled to a fraction of a
share of United Capital Stock but for the rounding required under Section 1.6(a)
(after aggregating all fractional shares of United Capital Stock to be received
by such holder) shall be entitled to receive from United an amount of cash
(rounded up to the nearest whole cent) equal to the product of (a) such
fraction, multiplied by (b) the average of the closing prices of United's Common
Stock for the ten (10) trading days ended on the last trading day prior to the
Effective Time (the "Closing Price").

             (g)  Intentionally Omitted.

         1.7 Dissenting Shares.

             (a)  Notwithstanding any provision of this Agreement to the
contrary, any shares of Lothian Capital Stock held by a holder who has demanded
and perfected dissenters' rights for such shares in accordance with the DGCL,
who, as of the Effective Time, has not effectively withdrawn or lost such
dissenters' rights ("Dissenting Shares") shall not be converted into or
represent a right to receive United Capital Stock pursuant to Section 1.6
(except as provided in Section 1.7(b)) but the holder thereof shall only be
entitled to such rights as are granted by the DGCL.

                                       5
<PAGE>

             (b)  Notwithstanding the provisions of Section 1.7(a) above, if any
holder of shares of Lothian Capital Stock who demands purchase of such shares
under the DGCL shall effectively withdraw or lose (through failure to perfect or
otherwise) such holder's dissenters' rights, then, as of the later of (i) the
Effective Time or (ii) the occurrence of such event, such holder's shares of
Lothian Capital Stock shall automatically be converted into and represent only

Stock pursuant to Section 1.6, (i) a letter of transmittal in the form attached
hereto as Exhibit C and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for certificates representing shares of United
Capital Stock and cash in lieu of fractional shares. Upon surrender of a
Certificate for cancellation (or, if such Certificate is lost, of a lost
Certificate affidavit and indemnity agreement in customary form) to the Exchange

to applicable Law, following surrender of any such Certificate, there shall be
paid to the record holder of the certificates representing whole shares of
United Capital Stock issued in exchange therefor, without interest, at the time
of such surrender, the amount of dividends or other distributions with a record
date after the Effective Time theretofore payable (but for the provisions of
this Section 1.8(c)) with respect to such whole shares of United Capital Stock.

             (d) Transfers of Ownership. If any certificate for shares of United
Capital Stock is to be issued pursuant to the Merger in a name other than that
in which the Certificate surrendered in exchange therefor is registered, it will
be a condition of the issuance thereof that the Certificate so surrendered will
be properly endorsed and otherwise in proper form for transfer and that the
person requesting such exchange will have paid to United or any agent designated
by it any transfer or other taxes required by reason of the issuance of a
certificate for shares of United Capital Stock in any name other than that of
the registered holder of the Certificate surrendered, or established to the
satisfaction of United or any agent designated by it that such tax has been paid
or is not payable.

United Capital Stock issued upon the surrender for exchange of shares of Lothian
Capital Stock in accordance with the terms hereof (including any cash in lieu of
fractional shares) shall be deemed to have been issued in full satisfaction of
all rights pertaining to such shares of Lothian Capital Stock, and there shall
be no further registration of transfers on the records of Lothian of shares of
Lothian Capital Stock which were outstanding immediately prior to the Effective
Time. If, after the Effective Time, Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Article I.

         1.10 Lost, Stolen or Destroyed Certificates. In the event any
Certificates shall have been lost, stolen or destroyed, the owner of such lost,
stolen or destroyed Certificates shall provide United with an affidavit of that
fact and indemnity in standard form.

         1.11 Further Action. If, at any time after the Effective Time, any such
further action is necessary or desirable to carry out the purposes of this
Agreement or to vest the Surviving Corporation with full right, title and
possession to all assets, property, rights, privileges, powers and franchises of
Lothian, the officers and directors of the Surviving Corporation are fully
authorized to take, and will take, all such lawful and necessary action.

                    REPRESENTATIONS AND WARRANTIES OF LOTHIAN

         Lothian hereby represents and warrants to United, subject to such
exceptions and qualifications as are specifically disclosed in the Lothian

conducted and as currently proposed to be conducted and to own, use, license and
lease its Assets and Properties. Lothian and each of the Lothian Subsidiaries is
duly qualified, licensed or admitted to do business and is in good standing as a

Section 2.9 of the Lothian Disclosure Schedule, Lothian has no material
Liabilities, other than Liabilities incurred in the ordinary course of business
consistent with past practice since the Lothian Financial Statement Date.

         2.10 Taxes.

             (a)  All Tax Returns, statements, reports, declarations and other
forms and documents (including without limitation estimated Tax Returns and
reports and material information statements, returns and reports) required to be

before the Effective Time, by or on behalf of Lothian, have been or will be
completed and filed when due (including any extensions of such due date) and all
amounts shown due on such Tax Returns on or before the Effective Time have been
or will be paid on or before such date. All such Tax Returns are true, accurate
and complete as filed. The Lothian December 31, 2005 unaudited balance sheet
included in the Lothian Financial Statements (the "Lothian Balance Sheet") (i)
fully accrues all Lothian's actual and contingent liabilities for Taxes with
respect to all periods through December 31, 2005 and Lothian has not and will
not incur any Tax liability in excess of the amount reflected on such Lothian

all material liabilities for Taxes payable after December 31, 2005 with respect
to all transactions and events occurring on or prior to such date. All

material Tax liability since December 31, 2005 has been or will be incurred by
Lothian other than in the ordinary course of business, and adequate provision
has been made by Lothian for all Taxes since that date in accordance with GAAP
on at least a quarterly basis.

true and correct copies of all Tax Returns. Lothian has withheld and paid to the
applicable financial institution or Taxing Authority all amounts required to be
withheld. Lothian (or any member of any affiliated or combined group of which
Lothian has been a member) has not granted any extension or waiver of the
limitation period applicable to any Tax Returns that is still in effect. There
is no material claim, audit, action, suit, proceeding, or (to the knowledge of
Lothian) investigation now pending or (to the knowledge of Lothian) threatened
against or with respect to Lothian in respect of any Tax or assessment. No
notice of deficiency or similar document of any Taxing Authority asserting that
Lothian has unpaid Tax liability has been received by Lothian, and there are no
liabilities for Taxes (including liabilities for interest, additions to Tax and
penalties thereon and related expenses) with respect to the issues that have
been raised (and are currently pending) by any Taxing Authority that could, if
determined adversely to Lothian, materially and adversely affect the liability
of Lothian for Taxes. There are no liens for Taxes (other than for current Taxes
not yet due and payable) upon the assets of Lothian. Lothian has never been a
member of an affiliated group of corporations, within the meaning of Section
1504 of the Code. Lothian is in full compliance with all the terms and
conditions of any Tax exemptions or other Tax-sharing agreement or order of a
foreign government and the consummation of the Merger will not have any adverse
effect on the continued validity and effectiveness of any such Tax exemption or
other Tax-sharing agreement or order. Neither Lothian nor any Person on behalf
of Lothian has entered into or will enter into any agreement or consent pursuant
to the collapsible corporation provisions of Section 341(f) of the Code (or any
corresponding provision of state, local or foreign income tax Law) or agreed to
have Section 341(f)(2) of the Code (or any corresponding provision of state,
local or foreign income tax Law) apply to any disposition of any asset owned by
Lothian. None of the assets of Lothian is property that Lothian is required to
treat as being owned by any other Person pursuant to the so-called "safe harbor
lease" provisions of former Section 168(f)(8) of the Code. None of the assets of
Lothian directly or indirectly secures any debt the interest on which is
tax-exempt under Section 103(a) of the Code. None of the assets of Lothian is
"tax-exempt use property" within the meaning of Section 168(h) of the Code.
Lothian has not made and will not make a deemed dividend election under Treas.
Reg. Section 1.1502-32(f)(2) or a consent dividend election under Section 565 of
the Code. Lothian has never been a party (either as a distributing corporation
or as a corporation that has been distributed) to any transaction intended to
qualify under Section 355 of the Code or any corresponding provision of state
Law. Lothian does not have and has not had a permanent establishment in any
foreign country, as defined in any applicable tax treaty or convention between
the United States of America and any such foreign country. Lothian has never
elected to be treated as an S-corporation under Section 1362 of the Code or any
corresponding provision of federal or state Law. All material elections with
respect to Lothian's Taxes made during the fiscal year ending, March 31, 2005
are reflected on the Lothian Tax Returns for such period, a copy of which have
been provided or made available to United. After the date of this Agreement, no
material election with respect to Taxes not made in the ordinary course of
business will be made without the prior written consent of United, which consent
will not be unreasonably withheld or delayed. Lothian is not party to any joint
venture, partnership, or other arrangement or contract which could be treated as
a partnership for federal income tax purposes. Lothian is not currently, and
never has been, subject to the reporting requirements of Section 6038A of the
Code. There is no agreement, contract or arrangement to which Lothian is a party
that could, individually or collectively, result in the payment of any amount
that would not be deductible by reason of Sections 280G (as determined without
regard to Section 280G(b)(4) and (5)), 162(a) (by reason of being unreasonable
in amount), 162 (b) through (p) or 404 of the Code. Lothian is not a party to or
bound by any Tax indemnity, Tax sharing or Tax allocation agreement (whether
written or unwritten or arising under operation of federal Law as a result of
being a member of a group filing consolidated Tax Returns, under operation of
certain state Laws as a result of being a member of a unitary group, or under
comparable Laws of other states or foreign jurisdictions) which includes a party
other than Lothian nor does Lothian owe any amount under any such Agreement.
Lothian is not, and has not been, a United States real property holding
corporation (as defined in Section 897(c)(2) of the Code) during the applicable
period specified in Section 897(c)(1)(A)(ii) of the Code. Other than by reason
of the Merger, Lothian has not been and will not be required to include any
material adjustment in Taxable income for any Tax period (or portion thereof)
pursuant to Section 481 or 263A of the Code or any comparable provision under
state or foreign Tax Laws as a result of transactions, events or accounting
methods employed prior to the Merger.

and complete as filed. United's December 31, 2005 unaudited balance sheet
included in the December 10-QSB (the "United Balance Sheet") (i) fully accrues
all United's actual and contingent liabilities for Taxes with respect to all
periods through December 31, 2005 and United has not and will not incur any Tax

limitation period applicable to any Tax Returns that is still in effect. There
is no material claim, audit, action, suit, proceeding, or (to the knowledge of
United) investigation now pending or (to the knowledge of United) threatened

liabilities for Taxes (including liabilities for interest, additions to Tax and
penalties thereon and related expenses) with respect to the issues that have
been raised (and are currently pending) by any Taxing Authority that could, if

United for Taxes. There are no liens for Taxes (other than for current Taxes not
yet due and payable) upon the assets of United. United has never been a member
of an affiliated group of corporations, within the meaning of Section 1504 of

of being unreasonable in amount), 162 (b) through (p) or 404 of the Code. United

group, or under comparable Laws of other states or foreign jurisdictions) which
includes a party other than United nor does United owe any amount under any such
Agreement. United is not, and has not been, a United States real property
holding corporation (as defined in Section 897(c)(2) of the Code) during the
applicable period specified in Section 897(c)(1)(A)(ii) of the Code. Other than
by reason of the Merger, United has not been and will not be required to include

thereof) pursuant to Section 481 or 263A of the Code or any comparable provision
under state or foreign Tax Laws as a result of transactions, events or
accounting methods employed prior to the Merger.

Effective Time, United will provide benefits to Lothian's employees as of the
Effective Time that are at least as favorable, taken as a whole, as the benefits
currently provided to employees of United performing functions similar to those

steps to (a) cause to be waived all limitations as to preexisting condition
limitations, exclusions and waiting periods with respect to participation and

severable, (b) this Agreement will be construed and enforced as if such illegal,
invalid or unenforceable provision had never comprised a part hereof, (c) the

                           UNITED HERITAGE CORPORATION

                     (Pursuant to Section 16-10a-602 of the
                     Utah Revised Business Corporation Act)

                  ---------------------------------------------

         United Heritage Corporation, a corporation organized and existing under
the laws of the State of Utah (the "Corporation"), hereby certifies that,
pursuant to authority vested in the Board of Directors of the Corporation by the
amended Articles of Incorporation of the Corporation, the following resolution
was adopted as of February ___, 2006 by the Board of Directors of the
Corporation pursuant to Section 16-10a-821 of the Utah Revised Business
Corporation Act:

         RESOLVED, that, pursuant to authority vested in the Board of Directors
of the Corporation by Article IV of the Corporation's amended Articles of
Incorporation, of the total authorized number of 5,000,000 shares of Preferred
Stock of the Corporation, there shall be designated a series of 133,333 shares
which shall be issued in and constitute a single series to be known as "Series A
Convertible Preferred Stock", par value $0.0001 per share (hereinafter called
the "Series A Preferred"). The shares of Series A Preferred shall have the
voting powers, designations, preferences and other special rights, and
qualifications, limitations and restrictions thereof set forth below:

         Section 1.        Dividends and Distributions.

         (a)  The holders of Series A Preferred shall be entitled to receive
dividends at a rate of eight percent (8%) of the liquidation preference of
$165.000165 per share per annum, which shall be fully cumulative, prior and in
preference to any declaration or payment of any dividend (payable other than in
shares of common stock, $0.001 par value per share, of the Corporation (the
"Common Stock") or other distribution on the Common Stock of the Corporation.
The holders of Series A Preferred shall not have preference but shall be
entitled to equal dividends or distributions to holders of subsequent series of
Preferred Stock issued by the Corporation, if any. If the dividends on the
Series A Preferred cannot legally be paid in full, dividends shall be paid, to
the maximum permissible extent, to the holders of the Series A Preferred, pari
passu. The dividends on the Series A Preferred shall accrue from the date of
issuance of each share and shall be payable quarterly with respect to each
calendar quarter on March 31, June 30, September 30 and December 31 of each year
(each a "Dividend Date"), commencing on the last day of the fiscal quarter in
which the effective date of Corporation's merger with Lothian Oil Inc. occurs
(with dividends being pro-rated for such quarter), to the holders of record of
the Series A Preferred on the first day of the month for each Dividend Date
(each, a "Record Date"), except that if any such date is a Saturday, Sunday or
legal holiday (a "Non-Business Day") then such dividend shall be payable on the
next day that is not a Saturday, Sunday or legal holiday on which banks in New
York, New York are required or authorized to be closed (a "Business Day"). The
dividends on the Series A Preferred shall be payable only when, as and if
declared by the Board of Directors out of funds legally available therefor. The
amount of dividends payable for any period that is shorter or longer than 30
days shall be computed on the basis of a 360-day year of twelve 30-day months.
All accrued but unpaid dividends shall accrue interest after each Dividend Date
at a rate of eight percent (8%) per annum from each Dividend Date, computed on
the basis of a 360-day year of twelve 30-day months.
<PAGE>

         (b) The holders of Series A Preferred shall not be entitled to receive
any dividends or other distributions except as provided in this Certificate of
Designation of Series A Preferred.

         Section 2.      Voting Rights.


         Except as otherwise required by law or as expressly provided herein,
each share of Series A Preferred shall entitle the holder thereof to notice of
any stockholders' meeting in accordance with the by-laws of the Corporation and
to vote upon all matters submitted to a vote of stockholders. Each share of
Series A Preferred shall be entitled the holder thereof to the number of votes
on any matter equal to the number of shares of Common Stock into which such
share of Series A Preferred could be converted on the record date for the vote
or written consent of stockholders with respect to such matter. Fractional votes
shall not, however, be permitted and any fractional voting rights (after
aggregating all shares of Common Stock into which shares of Series A Preferred
held by each holder could be converted) shall be rounded downward to the nearest
whole number. Except as otherwise required by law or expressly provided herein,
the holders of Series A Preferred and Common Stock shall vote together and not
as separate classes or series.

         Section 3.      Liquidation, Dissolution, Winding Up or Certain Mergers
                         or Consolidations.

         If the Corporation shall adopt a plan of liquidation or of dissolution,
or commence a voluntary case under the federal bankruptcy laws or any other
applicable state or federal bankruptcy, insolvency or similar law, or consent to
the entry of an order for relief in any involuntary case under such law or to
the appointment of a receiver, liquidator, assignee, custodian, trustee or
sequestrator (or similar official) of the Corporation or of any substantial part
of its property, or make an assignment for the benefit of its creditors, or
admit in writing its inability to pay its debts generally as they become due and
on account of such event the Corporation shall liquidate, dissolve or wind up,
or upon any other liquidation, dissolution or winding up of the Corporation, or
engage in a merger, plan of reorganization or consolidation in which the
Corporation is not the surviving Corporation, then and in that event, holders of
Series A Preferred shall have a liquidation preference over holders of Common
Stock, but shall not have a liquidation preference but shall be equal to holders
of subsequent series of Preferred Stock issued by the Corporation, if any. If
upon any liquidation, dissolution, winding up, merger, plan of reorganization or
consolidation, the amount so payable or distributable does not equal or exceed
the "Liquidation Preferences" of the Series A Preferred, then, and in that
event, the amount of cash so payable, and amount of securities or other
consideration so distributable, shall be shared ratably among the holders of the
Series A Preferred and any subsequent series of Preferred Stock issued by the
Corporation. For the purposes hereof, the term "Liquidation Preference(s)" shall
mean $165.000165 per share with respect to each of the Series A Preferred, plus
any and all accrued unpaid dividends thereon.

         Section 4.      Redemption.

         (a)  All, but not less than all, of the Series A Preferred may be
redeemed upon payment of $165.000165 per Series A Share, plus accrued and unpaid
dividends thereon (the "Redemption Price"), at any time by the Corporation at
its sole discretion upon thirty (30) days' written notice to the holders of the
Series A Preferred; provided, however, the Company shall not redeem the Series A
Preferred unless, at the time of such redemption, (i) the Company is a reporting
company under Section 12 of the Securities Exchange Act of 1934, as amended, and
(ii) the Common Stock is traded on the NASDAQ System or in the domestic
over-the-counter market as reported by the National Quotation Bureau,
Incorporated, or the American Stock Exchange, (iii) a registration statement
under the Securities Act of 1933, as amended has been filed and is effective and
covers the Common Stock issuable upon conversion of the Series A Preferred; and
(iv) the Market Price as of the date of any Redemption Notice hereunder is no
less than two hundred percent (200%) of the Conversion Ratio.

         (b)  Any notice of redemption (a "Redemption Notice") given by the
Corporation with respect to the Series A Preferred shall be delivered by mail,
first class postage prepaid, to each holder of record (at the close of business
on the business day preceding the day on which notice is given) of the Series A
Preferred, at the address last shown on the records of the Corporation for such
holder or given by the holder to the Corporation, for the purpose of notifying
such holder of the redemption to be effected. The Redemption Notice shall
specify a date (the "Redemption Date") not earlier than 30 days after the
mailing of the Redemption Notice on which the Series A Preferred then
outstanding shall be redeemed and the place at which payment may be obtained,
which shall be the principal offices of the Corporation. The Redemption Notice
shall call upon each holder of Series A Preferred to either (i) surrender to the
Corporation, in the manner and at the place designated, such holder's
certificate or certificates representing the Series A Preferred to be redeemed,
or (ii) convert the Series A Preferred into Common Stock prior to the Redemption
Date in accordance with the provisions of Section 5 below. If the Corporation
elects to redeem shares pursuant to this Section 4 and defaults or fails to
perform its redemption obligations pursuant to this Section 4 in connection
therewith, the holders of the Series A Preferred shall then have the absolute
right to convert such Series A Preferred into Common Stock in accordance with
the provisions of Section 5.

         (c)  On the Redemption Date, the Corporation shall pay the Redemption
Price to the person whose name appears on the certificate or certificates of the
Series A Preferred that (i) shall not have been converted pursuant to Section 5
hereof and (ii) shall have been surrendered to the Corporation in the manner and
at the place designated in the Redemption Notice, and thereupon each surrendered
certificate shall be canceled.

         (d)  If the funds of the Corporation legally available for redemption
of the Series A Preferred are insufficient to redeem the total number of Series
A Preferred outstanding on the Redemption Date, the Series A Preferred shall be
redeemed (on a pro rata basis from the holders of the Series A Preferred, from
time to time), to the extent the Corporation is legally permitted to do so, and
the redemption obligations of the Corporation hereunder will be a continuing
obligation until the Corporation's redemption of all of the Series A Preferred.

                                       3
<PAGE>

         (e)  From and after the Redemption Date, unless there shall have been a
default in payment of the Redemption Price, all rights of the holders of the
Series A Preferred (except the right to receive the Redemption Price subsequent
to the Redemption Date upon surrender of their certificate or certificates)
shall cease with respect to such shares, and such shares shall not thereafter be
transferred on the books of the Corporation or be deemed to be outstanding for
any purpose whatsoever.

         Section 5.      Conversion.

         (a)  Right to Convert: Subject to the provisions for adjustment
hereinafter set forth, each share of Series A Preferred shall be convertible in
the manner hereinafter set forth into fully paid and nonassessable shares of
Common Stock. Commencing upon issuance, the Liquidation Preference of each share
of Series A Preferred (a "Series A Share") may, at the option of the holder
thereof, be converted into such number of fully paid and nonassessable whole
shares of Common Stock as determined by dividing the Liquidation Preference by
$1.65000165 (the "Conversion Ratio"). Such rights of conversion shall be
exercised by the holder thereof by giving written notice that the holder elects
to convert a stated number of shares of Series A Preferred into Common Stock and
by surrender of a certificate or certificates for the shares to be so converted
to the Corporation at its principal office (or such other office or agency of
the Corporation as the Corporation may designate by notice in writing to the
holder or holders of the Series A Preferred) at any time during its usual
business hours on the date set forth in such notice, together with a statement
of the name or names (with address), subject to compliance with applicable laws
to the extent such designation shall involve a transfer, in which the
certificate or certificates for shares of Common Stock.

              (i)   Adjustments to Conversion Ratio:  The Conversion Ratio shall
be adjusted from time to time as follows:

                    (A)  If and whenever the Corporation issues or sells, or in
accordance with paragraph 5(ii) is deemed to have issued or sold, any shares of
its Common Stock for a consideration per share less than the Conversion Ratio in
effect immediately prior to the time of such issue or sale, then immediately
upon such issue or sale or deemed issue or sale the Conversion Ratio shall be
reduced to eighty-five percent (85%) of the per share consideration received by
the Corporation for such shares of Common Stock issued or deemed to have been
issued.

                         As used herein, "Common Stock Deemed Outstanding"
means, at any given time, without duplication, the number of shares of Common
Stock actually outstanding at such time, plus the number of shares of Common
Stock deemed to be outstanding pursuant to subparagraphs 5(a)(ii)(A) and
5(a)(ii)(B) hereof whether or not the Options or Convertible Securities (as such
terms are defined in subparagraph 5(a)(ii)(A) below) are actually exercisable at
such time, plus the number of shares of Common Stock issuable upon exercise of
Options outstanding at such time, as such number of shares is proportionately
adjusted for stock splits, stock dividends, stock combinations and other
recapitalizations.

                    (B)  Notwithstanding the foregoing, there shall be no
adjustment in the Conversion Ratio as a result of (a) the issuance of any Common
Stock as a result of the exercise of any Options outstanding at the time of the
initial issuance of the Series A Preferred, (b) the issuance of any Common Stock
as a result of the conversion of the Series A Preferred, (c) the issuance or
deemed issuance of any Common Stock as a result of the granting by the Company
of any Options approved by the Corporation's Board of Directors, to the extent
that the exercise price of any such Option is not less than eighty-five percent
(85%) of the Conversion Ratio on the date such Option is granted, or (d) the
issuance or deemed issuance of any Common Stock in connection with any
transaction or series of transactions (other than transactions specifically
described in this subsection (B)) at a price not less than eighty-five percent
(85%) of the Conversion Ratio on the date of issuance or deemed issuance and in
which the consideration received by the Company is not more than $1,000,000, in
one transaction or a series of transactions.

                  (ii)   Effect on Conversion Ratio of Certain Events. For
purposes of determining the adjusted Conversion Ratio under paragraph 5(a)(i)
above, the following shall be applicable:

                         (A) Issuance of Rights or Options. If the Corporation
in any manner grants or sells any rights, warrants or options (collectively,
"Options") to subscribe for or purchase Common Stock (other than Options
described in subparagraph 5(a)(i)(B) above) or any stock or securities directly
or indirectly convertible into or exchangeable for Common Stock ("Convertible
Securities") and the price per share for which Common Stock is issuable upon the
exercise of such Options, or upon conversion or exchange of any Convertible
Securities issuable upon exercise of such Options, is less than the Conversion
Ratio in effect immediately prior to the time of the granting or sale of such
Options, then the total maximum number of shares of Common Stock issuable upon
the exercise of such Options or upon conversion or exchange of the total maximum
amount of such Convertible Securities issuable upon the exercise of such Options
shall be deemed to be outstanding and to have been issued and sold by the
Corporation at the time of the granting or sale of such Options for such price
per share. For purposes of this paragraph, the "price per share for which Common
Stock is issuable" shall be determined by dividing (A) the total amount, if any,
received or receivable by the Corporation as consideration for the granting or
sale of such Options, plus the minimum aggregate amount of additional
consideration payable to the Corporation upon exercise of all such Options, plus
in the case of such Options which relate to Convertible Securities, the minimum
aggregate amount of additional consideration, if any, payable to the Corporation
upon the issuance or sale of such Convertible Securities and the conversion or
exchange thereof, by (B) the total maximum number of shares of Common Stock
issuable upon the exercise of such Options or upon the conversion or exchange of
all such Convertible Securities issuable upon the exercise of such Options. No
further adjustment of the Conversion Ratio shall be made when Convertible
Securities are actually issued upon the exercise of such Options or when Common
Stock is actually issued upon the exercise of such Options or the conversion or
exchange of such Convertible Securities.

                         (B) Issuance of Convertible Securities. If the
Corporation in any manner issues or sells any Convertible Securities and the
price per share for which Common Stock is issuable upon conversion or exchange
thereof is less than the Conversion Ratio in effect immediately prior to the
time of such issue or sale, then the maximum number of shares of Common Stock
issuable upon conversion or exchange of such Convertible Securities shall be
deemed to be outstanding and to have been issued and sold by the Corporation at
the time of the issuance or sale of such Convertible Securities for such price
per share. For the purposes of this paragraph, the "price per share for which
Common Stock is issuable" shall be determined by dividing (A) the total amount
received or receivable by the Corporation as consideration for the issue or sale
of such Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Corporation upon the conversion or
exchange thereof, by (B) the total maximum number of shares of Common Stock
issuable upon the conversion or exchange of all such Convertible Securities. No
further adjustment of the Conversion Ratio shall be made when Common Stock is
actually issued upon the conversion or exchange of such Convertible Securities,
and if any such issue or sale of such Convertible Securities is made upon
exercise of any Options for which adjustments of the Conversion Ratio had been
or are to be made pursuant to other provisions of this Section 5, no further
adjustment of the Conversion Ratio shall be made by reason of such issue or
sale.

                                       5
<PAGE>

                         (C) Change in Option Price or Conversion Rate. If the
purchase price provided for in any Options, the additional consideration, if
any, payable upon the conversion or exchange of any Convertible Securities or
the rate at which any Convertible Securities are convertible into or
exchangeable for Common Stock changes at any time, the Conversion Ratio in
effect at the time of such change shall be immediately adjusted to the
Conversion Ratio which would have been in effect at such time had such Options
or Convertible Securities still outstanding provided for such changed purchase
price, additional consideration or conversion rate, as the case may be, at the
time initially granted, issued or sold. For purposes of paragraph 5(a)(ii), if
the terms of any Option or Convertible Security which was outstanding as of the
date of the initial issuance of the Series A Preferred are changed in the manner
described in the immediately preceding sentence, then such Option or Convertible
Security and the Common Stock deemed issuable upon exercise, conversion or
exchange thereof shall be deemed to have been issued as of the date of such
change; provided that no such change shall at any time cause the Conversion
Ratio hereunder to be increased.

                         (D) Treatment of Expired Options and Unexercised
Convertible Securities. Upon the expiration of any Option or the termination of
any right to convert or exchange any Convertible Security without the exercise
of any such Option or right, the Conversion Ratio then in effect hereunder shall
be adjusted immediately to the Conversion Ratio which would have been in effect
at the time of such expiration or termination had such Option or Convertible
Security, to the extent outstanding immediately prior to such expiration or
termination, never been issued. For purposes of paragraph 5(a)(ii), the
expiration or termination of any Option or Convertible Security which was
outstanding as of the date of the initial issuance of the Series A Preferred
shall not cause the Conversion Ratio hereunder to be adjusted unless, and only
to the extent that, a change in the terms of such Option or Convertible Security
caused it to be deemed to have been issued after the date of issuance of the
Series A Preferred.

                         (E) Calculation of Consideration Received. If any
Common Stock, Option or Convertible Security is issued or sold or deemed to have
been issued or sold for cash, the consideration received therefor shall be
deemed to be the amount received by the Corporation therefor (net of
non-customary discounts, commissions and related expenses). If any Common Stock,
Option or Convertible Security is issued or sold for a consideration other than
cash, the amount of the consideration other than cash received by the
Corporation shall be the fair value of such consideration, except where such
consideration consists of securities, in which case the amount of consideration
received by the Corporation shall be the Market Price thereof as of the date of
receipt. If any Common Stock, Option or Convertible Security is issued to the
owners of the non-surviving entity in connection with any merger in which the
Corporation is the surviving corporation, the amount of consideration therefor
shall be deemed to be the fair value of such portion of the assets and business
of the non-surviving entity as is attributable to such Common Stock, Option or
Convertible Security, as the case may be. The fair value of any consideration
other than cash and securities shall be determined jointly by the Corporation
and the holders of at least a majority of the then outstanding Series A
Preferred. If such parties are unable to reach agreement within a reasonable
period of time, the fair value of such consideration shall be determined by an
independent appraiser experienced in valuing such type of consideration selected
by the Corporation and approved by the holders of at least a majority of the
then outstanding Series A Preferred (such approval not to be unreasonably
withheld). The determination of such appraiser shall be final and binding upon
the parties, and the fees and expenses of such appraiser shall be borne by the
Corporation.

                                       6
<PAGE>

                         (F) Integrated Transactions. In case any Option is
issued in connection with the issue or sale of other securities of the
Corporation, together comprising one integrated transaction in which no specific
consideration is allocated to such Option by the parties thereto, the Option
shall be deemed to have been issued for a consideration of One Cent ($.01).

                         (G) Treasury Shares. The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or
for the account of the Corporation or any Subsidiary, and the disposition of any
shares so owned or held shall be considered an issue or sale of Common Stock.

                         (H) Record Date. If the Corporation takes a record of
the holders of Common Stock for the purpose of entitling them (a) to receive a
dividend or other distribution payable in Common Stock, Options or in
Convertible Securities or (b) to subscribe for or purchase Common Stock, Options
or Convertible Securities, then such record date shall be deemed to be the date
of the issue or sale of the shares of Common Stock deemed to have been issued or
sold upon the declaration of such dividend or upon the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                         (I) "Market Price" of any security means the average
of the closing prices of such security's sales on all securities exchanges on
which such security may at the time be listed, or, if there has been no sales on
any such exchange on any day, the average of the highest bid and lowest asked
prices on all such exchanges at the end of such day, or, if on any day such
security is not so listed, the average of the representative bid and asked
prices quoted in the NASDAQ System as of 4:00 P.M., New York time, or, if on any
day such security is not quoted in the NASDAQ System, the average of the highest
bid and lowest asked prices on such day in the domestic over-the-counter market
as reported by the National Quotation Bureau, Incorporated, or any similar
successor organization, in each such case averaged over a period of twenty-one
(21) trading days consisting of the day as of which "Market Price" is being
determined and the twenty (20) consecutive business days prior to such day. If
at any time such security is not listed on any securities exchange or quoted in
the NASDAQ System or the over-the-counter market, the "Market Price" of any
security shall be the negotiated price thereof in any arm-length transaction
involving the Corporation, or, if no such transaction is then occurring, the
"Market Price" shall be the fair value thereof determined jointly by the
Corporation and the holders of at least a majority of the then outstanding
Series A Preferred. If such parties are unable to reach agreement within a
reasonable period of time, the Market Price shall be determined by an
independent appraiser experienced in valuing securities selected by the
Corporation. The determination of such appraiser shall be final and binding upon
the parties, and the Corporation shall pay the fees and expenses of such
appraiser.

                  (iii)  In case the Corporation shall at any time subdivide its
outstanding shares of Common Stock into a greater number of shares or shall
deduct or pay a dividend on its outstanding shares of Common Stock payable in
shares of Common Stock, the Conversion Ratio in effect immediately prior to such
subdivision shall be proportionately reduced, and conversely, in case the
outstanding shares of Common Stock of the Corporation shall be combined into a
small number of shares, the Conversion Ratio in effect immediately prior to such
combination shall be proportionately increased.

                                       7
<PAGE>

                  (iv)   Notices. Immediately upon any adjustment of the
Conversion Ratio, the Corporation shall give written notice thereof to all
holders of Series A Preferred, setting forth in reasonable detail and certifying
the calculation of such adjustment.

         (b) Reclassifications. In the case, at any time after the date hereof,
of any capital reorganization or any reclassification of the stock of the
Corporation (other than as a result of a stock dividend or subdivision, split-up
or combination of shares), or the consolidation or merger of the Corporation
with or into another person (other than a consolidation or merger (i) in which
the Corporation is the continuing entity and which does not result in any change
in the Common Stock or (ii) which is treated as a liquidation pursuant to
Section 3 hereof), the Series A Preferred shall, after such reorganization,
reclassification, consolidation or merger be convertible into the kind and
number of shares of stock or other securities or property of the Corporation or
otherwise to which such holder would have been entitled if immediately prior to
such reorganization, reclassification, consolidation or merger such holder had
converted its Series A Preferred into Common Stock. The provisions of this
Section 5 shall similarly apply to successive reorganizations,
reclassifications, consolidations or mergers

         (c) Fractional Shares. In lieu of any fractional shares to which the
holder of a Series A Share would otherwise be entitled upon conversion, the
Corporation shall pay cash equal to such fraction multiplied by the fair market
value of one share of Common Stock as determined by the Board of Directors in
the good faith exercise of its reasonable business judgment.

         (d) Intentionally Omitted.

         Section 6.  Registration of Transfer.

         The Corporation shall keep at its principal office a register for the
registration of Series A Preferred. Upon the surrender of any certificate
representing Series A Preferred at such place, the Corporation shall, at the
request of the record holder of such certificate, execute and deliver (at the
Corporation's expense) a new certificate or certificates in exchange therefor
representing in the aggregate the number of Series A Preferred shares
represented by the surrendered certificate. Each such new certificate shall be
registered in such name and shall represent such number of Series A Preferred
shares as is requested by the holder of the surrendered certificate and shall be
substantially identical in form to the surrendered certificate, and dividends
shall accrue on the Series A Preferred represented by such new certificate from
the date to which dividends have been fully paid on such Series A Preferred
represented by the surrendered certificate.

         Section 7.  Replacement.

         Upon receipt of evidence reasonably satisfactory to the Corporation (an
affidavit of the registered holder shall be satisfactory) of the ownership and
the loss, theft, destruction or mutilation of any certificate evidencing Series
A Preferred shares, and in the case of any such loss, theft or destruction, upon
receipt of indemnity reasonably satisfactory to the Corporation (provided that
if the holder is a financial institution or other institutional investor its own
agreement shall be satisfactory), or, in the case of any such mutilation upon
surrender of such certificate, the Corporation shall (at its expense) execute
and deliver in lieu of such certificate a new certificate of like kind
representing the number of Series A Preferred shares represented by such lost,
stolen, destroyed or mutilated certificate and dated the date of such lost,
stolen, destroyed or mutilated certificate, and dividends shall accrue on the
Series A Preferred represented by such new certificate from the date to which
dividends have been fully paid on such lost, stolen, destroyed or mutilated
certificate.

                                       8
<PAGE>

         Section 8.   No Pre-Emptive Rights.

         The holders of Series A Preferred shall not have any pre-emptive rights
with respect to any issuance or sale of securities by the Corporation pursuant
to the Amended and Restated Certificate of Incorporation.

         Section 9.   No Impairment.

         The Corporation will not, through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Certificate of Designation and in the taking of all
such action as may be necessary or appropriate in order to protect the
conversion rights of the holders of the Series A Preferred against impairment.

         Section 10.  Reservation of Stock Issuable Upon Conversion.

         The Corporation 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 of the Series A Preferred, such number of its shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding Series A Preferred. If at any time the number of authorized
but unissued shares of Common Stock shall not be sufficient to effect the
conversion of all then outstanding Series A Preferred, the Corporation will take
such corporate action as may, in the opinion of its counsel, be necessary to
increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purpose.

         Section 11.  Amendment and Waiver.

         No amendment, modification or waiver shall be binding or effective with
respect to any provision of this Certificate of Designation without the prior
written consent of the holders of not less than fifty-one percent (51%) of the
then outstanding Series A Preferred; provided, however, the Corporation reserves
the right by amendment of this Certificate of Designation from time to time to
decrease the number of shares which constitute the Series A Preferred Stock (but
not below the number of shares thereof then outstanding) and in other respects
to amend this Certificate of Designation within the limitations provided by law,
this Certificate of Designation and the Certificate of Incorporation.

                     (Pursuant to Section 16-10a-602 of the
                     Utah Revised Business Corporation Act)

                    ----------------------------------------


         United Heritage Corporation, a corporation organized and existing under
the laws of the State of Utah (the "Corporation"), hereby certifies that,
pursuant to authority vested in the Board of Directors of the Corporation by the
amended Articles of Incorporation of the Corporation, the following resolution
was adopted as of February ___, 2006 by the Board of Directors of the
Corporation pursuant to Section 16-10a-821 of the Utah Revised Business
Corporation Act:

         RESOLVED, that, it is in the best interest of this Corporation, that in
addition to the 133,333 shares of Series A Convertible Preferred Stock, par
value $0.0001 per share (hereinafter call the "Series A Preferred"), to create a
new series of its Preferred Stock;

         RESOLVED FURTHER, that, pursuant to authority vested in the Board of
Directors of the Corporation by Article IV of the Corporation's amended Articles
of Incorporation, of the total authorized number of 5,000,000 shares of
Preferred Stock of the Corporation, there shall be designated a series of 30,303
shares which shall be issued in and constitute a single series to be known as
"Series B-1 Convertible Preferred Stock", par value $0.0001 per share
(hereinafter called the "Series B-1 Preferred") and there shall be designated a
series of 45,455 shares which shall be issued in and constitute a single series
to be known as "Series B-2 Convertible Preferred Stock", par value $0.0001 per
share (hereinafter called the "Series B-2 Preferred, and collectively with the
Series B-1 Preferred, the "Series B Preferred"). The shares of Series B
Preferred shall have the voting powers, designations, preferences and other
special rights, and qualifications, limitations and restrictions thereof set
forth below:

         Section 1.     Dividends and Distributions.

<PAGE>

         (a) The holders of Series B Preferred shall be entitled to receive
dividends at a rate of eight percent (8%) of the applicable liquidation
preference per share per annum, which shall be fully cumulative, prior and in
preference to any declaration or payment of any dividend (payable other than in
shares of common stock, $.001 par value per share, of the Corporation (the
"Common Stock") or other distribution on the Common Stock of the Corporation.
The holders of Series B Preferred shall not have preference but shall be
entitled to equal dividends or distributions to holders of the Series A
Preferred. If the dividends on all outstanding shares of Series A Preferred and
Series B Preferred cannot legally be paid in full, dividends shall be paid, to
the maximum permissible extent, to the holders of the Series A Preferred and the
Series B Preferred, pari passu. The dividends on the Series B Preferred shall
accrue from the date of issuance of each share and shall be payable quarterly
with respect to each calendar quarter on March 31, June 30, September 30 and
December 31 of each year (each a "Dividend Date"), commencing on the last day of
the fiscal quarter in which the effective date of the Corporation's merger with
Lothian Oil Inc. occurs (with dividends being pro-rated for such quarter), to
the holders of record of the Series B Preferred on the first day of the month
for each Dividend Date (each, a "Record Date"), except that if any such date is
a Saturday, Sunday or legal holiday (a "Non-Business Day") then such dividend
shall be payable on the next day that is not a Saturday, Sunday or legal holiday
on which banks in New York, New York are required or authorized to be closed (a
"Business Day"). The dividends on the Series B Preferred shall be payable only
when, as and if declared by the Board of Directors out of funds legally
available therefor. The amount of dividends payable for any period that is
shorter or longer than 30 days shall be computed on the basis of a 360-day year
of twelve 30-day months. All accrued but unpaid dividends shall accrue interest
after each Dividend Date at a rate of eight percent (8%) per annum from each
Dividend Date, computed on the basis of a 360-day year of twelve 30-day months.

         (b) The holders of Series B Preferred shall not be entitled to receive
any dividends or other distributions except as provided in this Certificate of
Designation of Series B Preferred.

         Section 2.     Voting Rights.

         Except as otherwise required by law or as expressly provided herein,
each share of Series B Preferred shall entitle the holder thereof to notice of
any stockholders' meeting in accordance with the by-laws of the Corporation and
to vote upon all matters submitted to a vote of stockholders. Each share of
Series B Preferred shall entitle the holder thereof to the number of votes on
any matter equal to the number of shares of Common Stock into which such share
of Series B Preferred could be converted on the record date for the vote or
written consent of stockholders with respect to such matter. Fractional votes
shall not, however, be permitted and any fractional voting rights (after
aggregating all shares of Common Stock into which shares of Series B Preferred
held by each holder could be converted) shall be rounded downward to the nearest
whole number. Except as otherwise required by law or expressly provided herein,
the holders of Series B Preferred and Common Stock shall vote together and not
as separate classes or series.

         At each meeting or pursuant to each consent of the Corporation's
stockholders for the election of directors, the holders of Series B-1 Preferred,
voting as a separate class, shall be entitled to elect one (1) member of the
Corporation's Board of Directors. Any additional members of the Corporation's
Board of Directors shall be elected by the holders of Common Stock and Preferred
Stock, voting together as a single class. If a vacancy on the Board of Directors
is to be filled by the Board of Directors, only directors elected by the same
class or classes of stockholders as those who would be entitled to vote to fill
such vacancy shall vote to fill such vacancy.

         Section 3.     Liquidation, Dissolution, Winding Up or Certain Mergers
or Consolidations.

                                       2
<PAGE>

         If the Corporation shall adopt a plan of liquidation or of dissolution,
or commence a voluntary case under the federal bankruptcy laws or any other
applicable state or federal bankruptcy, insolvency or similar law, or consent to
the entry of an order for relief in any involuntary case under such law or to
the appointment of a receiver, liquidator, assignee, custodian, trustee or
sequestrator (or similar official) of the Corporation or of any substantial part
of its property, or make an assignment for the benefit of its creditors, or
admit in writing its inability to pay its debts generally as they become due and
on account of such event the Corporation shall liquidate, dissolve or wind up,
or upon any other liquidation, dissolution or winding up of the Corporation, or
engage in a merger, plan of reorganization or consolidation in which the
Corporation is not the surviving Corporation (collectively, a "Liquidation
Event"), then and in that event, holders of Series B Preferred shall have a
liquidation preference over holders of Common Stock, but shall not have a
liquidation preference over but shall be equal to holders of Series A Preferred
and senior to distributions to any other class or series of the Corporation's
stock . If upon any Liquidation Event, the amount so payable or distributable
does not equal or exceed the "Liquidation Preferences" of the Series A Preferred
and Series B Preferred, then, and in that event, the amount of cash so payable,
and amount of securities or other consideration so distributable, shall be
shared ratably among the holders of the Series A Preferred and the Series B
Preferred. For the purposes hereof, the term "Liquidation Preference(s)" for the
Series A Preferred shall have the meaning provided in the Certificate of
Designation, Preferences and Rights of Series A Preferred Stock filed by the
Corporation with the Utah Secretary of State simultaneously with the filing of
this Certificate of Designation, and for the Series B Preferred shall mean
$165.000165 per share with respect to each of the Series B-1 Preferred, and
$206.25020625 per share with respect to each of the Series B-2 Preferred, in all
cases plus any and all accrued unpaid dividends thereon. For the purposes of
this Section 3, holders of a majority of the Series B Preferred then outstanding
may by affirmative vote or written consent deem any transaction specified in
this Section 3 not to constitute a Liquidation Event.

         Section 4.     Redemption.

         (a) All, but not less than all, of the Series B-1 Preferred may be
redeemed upon payment of $165.000165 per share of Series B-1 Preferred and all,
but not less than all, of the Series B-2 Preferred may be redeemed upon payment
of $206.25020625 per share, in all cases plus accrued and unpaid dividends
thereon (the "Redemption Price"), at any time by the Corporation at its sole
discretion upon thirty (30) days' written notice to the holders of the
applicable Series B Preferred; provided, however, the Company shall not redeem
any Series B Preferred unless, at the time of such redemption, (i) the Company
is a reporting company under Section 12 of the Securities Exchange Act of 1934,
as amended, and (ii) the Common Stock is traded on the NASDAQ System or in the
domestic over-the-counter market as reported by the National Quotation Bureau,
Incorporated, or the American Stock Exchange, and (iii) a registration statement
under the Securities Act of 1933, as amended has been filed and is effective and
covers the Common Stock issuable upon conversion of the Series B Preferred; and
(iv) the Market Price as of the date of any Redemption Notice hereunder is no
less than two hundred percent (200%) of the Conversion Ratio.

         (b) Any notice of redemption (a "Redemption Notice") given by the
Corporation with respect to the applicable Series B Preferred shall be delivered
by mail, first class postage prepaid, to each holder of record (at the close of
business on the business day preceding the day on which notice is given) of the
applicable Series B Preferred, at the address last shown on the records of the
Corporation for such holder or given by the holder to the Corporation, for the
purpose of notifying such holder of the redemption to be effected. The
Redemption Notice shall specify a date (the "Redemption Date") not earlier than
30 days after the mailing of the Redemption Notice on which the applicable
Series B Preferred then outstanding shall be redeemed and the place at which
payment may be obtained, which shall be the principal offices of the
Corporation. The Redemption Notice shall call upon each holder of the applicable
Series B Preferred to either (i) surrender to the Corporation, in the manner and
at the place designated, such holder's certificate or certificates representing
the Series B Preferred to be redeemed, or (ii) convert such Series B Preferred
into Common Stock prior to the Redemption Date in accordance with the provisions
of Section 5 below. If the Corporation elects to redeem shares pursuant to this
Section 4 and defaults or fails to perform its redemption obligations pursuant
to this Section 4 in connection therewith, the holders of the applicable Series
B Preferred shall then have the absolute right to convert such Series B
Preferred into Common Stock in accordance with the provisions of Section 5.

                                       3
<PAGE>

         (c) On the Redemption Date, the Corporation shall pay the Redemption
Price to the person whose name appears on the certificate or certificates of the
applicable Series B Preferred that (i) shall not have been converted pursuant to
Section 5 hereof and (ii) shall have been surrendered to the Corporation in the
manner and at the place designated in the Redemption Notice, and thereupon each
surrendered certificate shall be canceled.

         (d) If the funds of the Corporation legally available for redemption of
the applicable Series B Preferred are insufficient to redeem the total number of
such shares of Series B Preferred outstanding on the Redemption Date, the
applicable Series B Preferred shall be redeemed (on a pro rata basis from the
holders of such Series B Preferred, from time to time), to the extent the
Corporation is legally permitted to do so, and the redemption obligations of the
Corporation hereunder will be a continuing obligation until the Corporation's
redemption of all of the applicable Series B Preferred.

         (e) From and after the Redemption Date, unless there shall have been a
default in payment of the Redemption Price, all rights of the holders of the
Series B Preferred (except the right to receive the Redemption Price subsequent
to the Redemption Date upon surrender of their certificate or certificates)
shall cease with respect to such shares, and such shares shall not thereafter be
transferred on the books of the Corporation or be deemed to be outstanding for
any purpose whatsoever.

         Section 5.     Conversion.

         (a) Right to Convert: Subject to the provisions for adjustment
hereinafter set forth, each share of Series B Preferred shall be convertible in
the manner hereinafter set forth into fully paid and nonassessable shares of
Common Stock. Commencing upon issuance, each share of Series B-1 Preferred may,
at the option of the holder thereof, be converted into such number of fully paid
and nonassessable whole shares of Common Stock as determined by dividing the
Liquidation Preference by $1.65000165, and each share of Series B-2 Preferred
may, at the option of the holder thereof, be converted into such number of fully
paid and nonassessable whole shares of Common Stock as determined by dividing
the Liquidation Preference by $2.0625020625 (the "Conversion Ratio"). Such
rights of conversion shall be exercised by the holder thereof by giving written
notice to the Corporation that the holder elects to convert a stated number of
shares of the applicable Series B Preferred into Common Stock and by surrender
of a certificate or certificates for the shares to be so converted to the
Corporation at its principal office (or such other office or agency of the
Corporation as the Corporation may designate by notice in writing to the holder
or holders of the Series B Preferred) at any time during its usual business
hours on the date set forth in such notice, together with a statement of the
name or names, subject to compliance with applicable laws to the extent such
designation shall involve a transfer, in which the certificate or certificates
for shares of Common Stock are to be issued. The Corporation shall, as soon as
possible thereafter and in no case more than three (3) business days, issue and
deliver at such office to such holder of Series B Preferred, or to the nominee
or nominees of such holder, a certificate or certificates for the number of
shares of Common Stock to which such holder shall be entitled as aforesaid. Such
conversion shall be deemed to have been made immediately prior to the close of
business on the date of such surrender of the shares of the applicable Series B
Preferred to be converted, and the person or persons entitled to receive the
shares of Common Stock issuable upon such conversion shall be treated for all
purposes as the record holder or holders of such shares of Common Stock as of
such date.

                  (i)    Adjustments to Conversion Ratio:  The Conversion Ratio
shall be adjusted from time to time as follows:

                         (A) If and whenever the Corporation issues or sells,
or in accordance with paragraph 5(ii) is deemed to have issued or sold, any
shares of its Common Stock for a consideration per share less than the
applicable Conversion Ratio in effect immediately prior to the time of such
issue or sale, then immediately upon such issue or sale or deemed issue or sale
such Conversion Ratio shall be reduced to eighty-five percent (85%) of the per
share consideration received by the Corporation for such shares of Common Stock
issued or deemed to have been issued.

(a) As used herein, "Common Stock Deemed Outstanding" means, at any given time,
without duplication, the number of shares of Common Stock actually outstanding
at such time, plus the number of shares of Common Stock deemed to be outstanding
pursuant to subparagraphs 5(a)(ii)(A) and 5(a)(ii)(B) hereof whether or not the
Options or Convertible Securities (as such terms are defined in subparagraph
5(a)(ii)(A) below) are actually exercisable at such time, plus the number of
shares of Common Stock issuable upon exercise of Options outstanding at such
time, as such number of shares is proportionately adjusted for stock splits,
stock dividends, stock combinations and other recapitalizations.

                         (B) Notwithstanding the foregoing, there shall be no
adjustment in the Conversion Ratio as a result of (a) the issuance of any Common
Stock as a result of the exercise of any Options outstanding at the time of the
initial issuance of the Series B Preferred, (b) the issuance of any Common Stock
as a result of the conversion of the Series B Preferred, (c) the issuance or
deemed issuance of any Common Stock as a result of the granting by the Company
of any Options approved by the Corporation's Board of Directors, to the extent
that the exercise price of any such Option is not less than eighty-five percent
(85%) of the Conversion Ratio on the date such Option is granted, or (d) the
issuance or deemed issuance of any Common Stock in connection with any
transaction or series of transactions (other than transactions specifically
described in this subsection (B)) at a price not less than eighty-five percent
(85%) of the Conversion Ratio on the date of issuance or deemed issuance and in
which the consideration received by the Company is not more than $1,000,000, in
one transaction or a series of transactions.

                  (ii)   Effect on Conversion Ratio of Certain Events. For
purposes of determining the adjusted Conversion Ratio under paragraph 5(a)(i)
above, the following shall be applicable:

                                       5
<PAGE>

                         (A) Issuance of Rights or Options. If the Corporation
in any manner grants or sells any rights, warrants or options (collectively,
"Options") to subscribe for or purchase Common Stock (other than Options
described in subparagraph 5(a)(i)(B) above) or any stock or securities directly
or indirectly convertible into or exchangeable for Common Stock ("Convertible
Securities") and the price per share for which Common Stock is issuable upon the
exercise of such Options, or upon conversion or exchange of any Convertible
Securities issuable upon exercise of such Options, is less than the applicable
Conversion Ratio in effect immediately prior to the time of the granting or sale
of such Options, then the total maximum number of shares of Common Stock
issuable upon the exercise of such Options or upon conversion or exchange of the
total maximum amount of such Convertible Securities issuable upon the exercise
of such Options shall be deemed to be outstanding and to have been issued and
sold by the Corporation at the time of the granting or sale of such Options for
such price per share. For purposes of this paragraph, the "price per share for
which Common Stock is issuable" shall be determined by dividing (A) the total
amount, if any, received or receivable by the Corporation as consideration for
the granting or sale of such Options, plus the minimum aggregate amount of
additional consideration payable to the Corporation upon exercise of all such
Options, plus in the case of such Options which relate to Convertible
Securities, the minimum aggregate amount of additional consideration, if any,
payable to the Corporation upon the issuance or sale of such Convertible
Securities and the conversion or exchange thereof, by (B) the total maximum
number of shares of Common Stock issuable upon the exercise of such Options or
upon the conversion or exchange of all such Convertible Securities issuable upon
the exercise of such Options. No further adjustment of the applicable Conversion
Ratio shall be made when Convertible Securities are actually issued upon the
exercise of such Options or when Common Stock is actually issued upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

                         (B) Issuance of Convertible Securities. If the
Corporation in any manner issues or sells any Convertible Securities and the
price per share for which Common Stock is issuable upon conversion or exchange
thereof is less than the applicable Conversion Ratio in effect immediately prior
to the time of such issue or sale, then the maximum number of shares of Common
Stock issuable upon conversion or exchange of such Convertible Securities shall
be deemed to be outstanding and to have been issued and sold by the Corporation
at the time of the issuance or sale of such Convertible Securities for such
price per share. For the purposes of this paragraph, the "price per share for
which Common Stock is issuable" shall be determined by dividing (A) the total
amount received or receivable by the Corporation as consideration for the issue
or sale of such Convertible Securities, plus the minimum aggregate amount of
additional consideration, if any, payable to the Corporation upon the conversion
or exchange thereof, by (B) the total maximum number of shares of Common Stock
issuable upon the conversion or exchange of all such Convertible Securities. No
further adjustment of the Conversion Ratio shall be made when Common Stock is
actually issued upon the conversion or exchange of such Convertible Securities,
and if any such issue or sale of such Convertible Securities is made upon
exercise of any Options for which adjustments of the Conversion Ratio had been
or are to be made pursuant to other provisions of this Section 5, no further
adjustment of the applicable Conversion Ratio shall be made by reason of such
issue or sale.

                         (C) Change in Option Price or Conversion Rate. If the
purchase price provided for in any Options, the additional consideration, if
any, payable upon the conversion or exchange of any Convertible Securities or
the rate at which any Convertible Securities are convertible into or
exchangeable for Common Stock changes at any time, the applicable Conversion
Ratio in effect at the time of such change shall be immediately adjusted to the
Conversion Ratio which would have been in effect at such time had such Options
or Convertible Securities still outstanding provided for such changed purchase
price, additional consideration or conversion rate, as the case may be, at the
time initially granted, issued or sold. For purposes of paragraph 5(a)(ii), if
the terms of any Option or Convertible Security which was outstanding as of the
date of the initial issuance of the Series B Preferred are changed in the manner
described in the immediately preceding sentence, then such Option or Convertible
Security and the Common Stock deemed issuable upon exercise, conversion or
exchange thereof shall be deemed to have been issued as of the date of such
change; provided that no such change shall at any time cause the applicable
Conversion Ratio hereunder to be increased.

                                       6
<PAGE>

                         (D) Treatment of Expired Options and Unexercised
Convertible Securities. Upon the expiration of any Option or the termination of
any right to convert or exchange any Convertible Security without the exercise
of any such Option or right, the applicable Conversion Ratio then in effect
hereunder shall be adjusted immediately to the Conversion Ratio which would have
been in effect at the time of such expiration or termination had such Option or
Convertible Security, to the extent outstanding immediately prior to such
expiration or termination, never been issued. For purposes of paragraph
5(a)(ii), the expiration or termination of any Option or Convertible Security
which was outstanding as of the date of the initial issuance of the Series B
Preferred shall not cause the applicable Conversion Ratio hereunder to be
adjusted unless, and only to the extent that, a change in the terms of such
Option or Convertible Security caused it to be deemed to have been issued after
the date of issuance of the Series B Preferred.

                         (E) Calculation of Consideration Received. If any
Common Stock, Option or Convertible
Security is issued or sold or deemed to have been issued or sold for cash, the
consideration received therefor shall be deemed to be the amount received by the
Corporation therefor (net of non-customary discounts, commissions and related
expenses). If any Common Stock, Option or Convertible Security is issued or sold
for a consideration other than cash, the amount of the consideration other than
cash received by the Corporation shall be the fair value of such consideration,
except where such consideration consists of securities, in which case the amount
of consideration received by the Corporation shall be the Market Price thereof
as of the date of receipt. If any Common Stock, Option or Convertible Security
is issued to the owners of the non-surviving entity in connection with any
merger in which the Corporation is the surviving corporation, the amount of
consideration therefor shall be deemed to be the fair value of such portion of
the assets and business of the non-surviving entity as is attributable to such
Common Stock, Option or Convertible Security, as the case may be. The fair value
of any consideration other than cash and securities shall be determined jointly
by the Corporation and the holders of a majority of the then outstanding Series
B Preferred. If such parties are unable to reach agreement within a reasonable
period of time, the fair value of such consideration shall be determined by an
independent appraiser experienced in valuing such type of consideration selected
by the Corporation and approved by the holders of a majority of the then
outstanding Series B Preferred (such approval not to be unreasonably withheld).
The determination of such appraiser shall be final and binding upon the parties,
and the fees and expenses of such appraiser shall be borne by the Corporation.

                         (F) Reserved.

                         (G) Treasury Shares. The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or
for the account of the Corporation or any Subsidiary, and the disposition of any
shares so owned or held shall be considered an issue or sale of Common Stock.

                         (H) Record Date. If the Corporation takes a record of
the holders of Common Stock for the purpose of entitling them (a) to receive a
dividend or other distribution payable in Common Stock, Options or in
Convertible Securities or (b) to subscribe for or purchase Common Stock, Options
or Convertible Securities, then such record date shall be deemed to be the date
of the issue or sale of the shares of Common Stock deemed to have been issued or
sold upon the declaration of such dividend or upon the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                                       7
<PAGE>

                         (I) "Market Price" of any security means the average
of the closing prices of such security's sales on all securities exchanges on
which such security may at the time be listed, or, if there has been no sales on
any such exchange on any day, the average of the highest bid and lowest asked
prices on all such exchanges at the end of such day, or, if on any day such
security is not so listed, the average of the representative bid and asked
prices quoted in the NASDAQ System as of 4:00 P.M., New York time, or, if on any
day such security is not quoted in the NASDAQ System, the average of the highest
bid and lowest asked prices on such day in the domestic over-the-counter market
as reported by the National Quotation Bureau, Incorporated, or any similar
successor organization, in each such case averaged over a period of twenty-one
(21) trading days consisting of the day as of which "Market Price" is being
determined and the twenty (20) consecutive business days prior to such day. If
at any time such security is not listed on any securities exchange or quoted in
the NASDAQ System or the over-the-counter market, the "Market Price" shall be
the fair value thereof determined jointly by the Corporation and the holders of
at least a majority of the then outstanding Series B Preferred. If such parties
are unable to reach agreement within a reasonable period of time, the Market
Price shall be determined by an independent appraiser selected by a majority of
the holders of the then outstanding Series B Preferred, which appraiser shall be
experienced in valuing securities selected by the Corporation. The determination
of such appraiser shall be final and binding upon the parties, and the
Corporation shall pay the fees and expenses of such appraiser.

                  (iii)  In case the Corporation shall at any time subdivide its
outstanding shares of Common Stock into a greater number of shares or shall
deduct or pay a dividend on its outstanding shares of Common Stock payable in
shares of Common Stock, the applicable Conversion Ratio in effect immediately
prior to such subdivision shall be proportionately reduced, and conversely, in
case the outstanding shares of Common Stock of the Corporation shall be combined
into a small number of shares, the applicable Conversion Ratio in effect
immediately prior to such combination shall be proportionately increased.

                  (iv)   Notices. Immediately upon any adjustment of any
Conversion Ratio, the Corporation shall give written notice thereof to all
holders of Series B Preferred, setting forth in reasonable detail and certifying
the calculation of such adjustment.

         (b) Reclassifications. In the case, at any time after the date hereof,
of any capital reorganization or any reclassification of the stock of the
Corporation (other than as a result of a stock dividend or subdivision, split-up
or combination of shares), or the consolidation or merger of the Corporation
with or into another person (other than a consolidation or merger (i) in which
the Corporation is the continuing entity and which does not result in any change
in the Common Stock or (ii) which is treated as a liquidation pursuant to
Section 3 hereof), the Series B Preferred shall, after such reorganization,
reclassification, consolidation or merger be convertible into the kind and
number of shares of stock or other securities or property of the Corporation or
otherwise to which such holder would have been entitled if immediately prior to
such reorganization, reclassification, consolidation or merger such holder had
converted its Series B Preferred into Common Stock. The provisions of this
Section 5 shall similarly apply to successive reorganizations,
reclassifications, consolidations or mergers

         (c) Fractional Shares. In lieu of any fractional shares to which the
holder of Series B Preferred Share would otherwise be entitled upon conversion,
the Corporation shall pay cash equal to such fraction multiplied by the Market
Price of one share of Common Stock.

                                       8
<PAGE>

         (d) Status of Converted Stock. In the event any shares of Series B
Preferred shall be converted pursuant to Section 5 hereof, the shares so
converted shall be cancelled and shall not be issuable by the Corporation. This
Certificate of Designations shall be appropriately amended to effect the
corresponding reduction in the Corporation's authorized capital stock

         Section 6.     Registration of Transfer.

         The Corporation shall keep at its principal office a register for the
registration of Series B Preferred. Upon the surrender of any certificate
representing Series B Preferred at such place, the Corporation shall, at the
request of the record holder of such certificate, execute and deliver (at the
Corporation's expense) a new certificate or certificates in exchange therefor
representing in the aggregate the number of Series B Preferred shares
represented by the surrendered certificate. Each such new certificate shall be
registered in such name and shall represent such number of Series B Preferred
shares as is requested by the holder of the surrendered certificate and shall be
substantially identical in form to the surrendered certificate, and dividends
shall accrue on the Series B Preferred represented by such new certificate from
the date to which dividends have been fully paid on such Series B Preferred
represented by the surrendered certificate.

         Section 7.     Replacement.

         Upon receipt of evidence reasonably satisfactory to the Corporation (an
affidavit of the registered holder shall be satisfactory) of the ownership and
the loss, theft, destruction or mutilation of any certificate evidencing Series
B Preferred shares, and in the case of any such loss, theft or destruction, upon
receipt of indemnity reasonably satisfactory to the Corporation (provided that
if the holder is a financial institution or other institutional investor its own
agreement shall be satisfactory), or, in the case of any such mutilation upon
surrender of such certificate, the Corporation shall (at its expense) execute
and deliver in lieu of such certificate a new certificate of like kind
representing the number of Series B Preferred shares represented by such lost,
stolen, destroyed or mutilated certificate and dated the date of such lost,
stolen, destroyed or mutilated certificate, and dividends shall accrue on the
Series B Preferred represented by such new certificate from the date to which
dividends have been fully paid on such lost, stolen, destroyed or mutilated
certificate.

         Section 8.     No Pre-Emptive Rights.

         The holders of Series B Preferred shall not have any pre-emptive rights
with respect to any issuance or sale of securities by the Corporation pursuant
to the Corporation's amended Articles of Incorporation.

         Section 9.     No Impairment.

         The Corporation will not, through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Certificate of Designation and in the taking of all
such action as may be necessary or appropriate in order to protect the
conversion rights of the holders of the Series B Preferred against impairment.

         Section 10.    Reservation of Stock Issuable Upon Conversion.


                                       9
<PAGE>

         The Corporation 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 of the Series B Preferred, such number of its shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding Series B Preferred. If at any time the number of authorized
but unissued shares of Common Stock shall not be sufficient to effect the
conversion of all then outstanding Series B Preferred, the Corporation will take
such corporate action as may, in the opinion of its counsel, be necessary to
increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purpose.

        MATTERS TO BE COVERED BY LEGAL OPINION OF RICHARDSON & PATEL LLP

Lothian Oil Inc.
500 Fifth Avenue, Suite 2600
New York, New York 10110

Gentlemen:

         We have acted as counsel to United Heritage Corporation, a Utah
corporation (the "Company"), in connection with the negotiation, execution and
delivery of the Merger Agreement and Plan of Reorganization, dated as of
February ___, 2006 (the "Merger Agreement"; capitalized terms used but not
defined herein shall have the respective meanings ascribed to them in the Merger
Agreement), by and among the Company and Lothian Oil Inc., a Delaware
corporation ("Lothian") and the Ancillary Agreements to which it is a party
(collectively, the "Transaction Documents").

         For purposes of rendering this opinion, we have limited our examination
to originals or copies, certified or otherwise identified to our satisfaction,
of the following: (i) the Transaction Documents, (ii) the amended Articles of
Incorporation and the Bylaws of the Company, (iii) resolutions of the Board of
Directors and of the stockholders of the Company, and (iv) a certificate of an
officer of the Company. We have assumed the genuiness of all signatures by or on
behalf of persons other than the Company and that all such signatories have been
duly authorized, the authenticity of all documents submitted to us as originals,
and the conformity with originals of all documents submitted to us as certified,
conformed or photostatic copies.

         Based solely upon and in reliance on the foregoing and subject in all
respects to the qualifications, limitations and assumptions set forth herein, it
is our opinion that:

         1. The Company is a corporation duly incorporated and organized,
validly existing and in good standing under the laws of the State of Utah.

         2. The Company is duly qualified as a foreign corporation to transact
business in, and is in good standing in the States of Texas.

         3. The Company has all necessary corporate power and authority to
execute, deliver and perform its obligations under the Transaction Documents to
which the Company is a party, and the Company has all necessary corporate power
and authority to own its properties and to conduct its business in the manner
and in the locations presently owned and conducted.

         4. The Transaction Documents have been duly authorized, executed and
delivered by the Company, and, assuming due authorization, execution and
delivery by the other parties thereto, each such agreement is a valid and
binding obligation of the Company, enforceable in accordance with its terms.

         5. The Certificate of Designation, Preferences and Rights of Series A
Preferred Stock and the Certificate of Designation, Preferences and Rights of
Series B Preferred Stock (the "Certificates of Designation") have been duly
adopted by the Company, have become effective under the laws of Utah and the
Certificates of Designation constitute valid and binding obligations of the
Company, enforceable in accordance with their respective terms.
<PAGE>

         6. The issuance of United Capital Stock to the Lothian stockholders has
been duly authorized by the Company, and when delivered in accordance with the
Merger Agreement such United Capital Stock will be validly issued, outstanding,
fully paid and nonassessable. To our knowledge, there are no contractual
preemptive rights of stockholders or rights of first refusal with respect to the
issuance of such United Capital Stock.

         7. The execution and delivery by the Company of the Transaction
Documents, and the performance of its obligations thereunder will not (i)
violate the Company's amended Articles of Incorporation, the Bylaws of the
Company, or to our knowledge, any law, statute, rule or regulation (exclusive of
local laws) applicable to the Company or any order, judgment or decree to which
the Company is subject. To our knowledge, no authorization, consent, approval,
exemption or other action by, or notice to, any court or administrative or
governmental body is required for any of the actions of the Company described in
this paragraph 7.

         8. The issuance of the United Capital Stock pursuant to the Merger
Agreement does not require registration under the Securities Act or registration
or qualification under any state securities laws. For purposes of the opinion
set forth in this paragraph 8, we have assumed that each Lothian stockholder is
an "accredited investor" as that term is defined in Rule 501(a) promulgated
under the Securities Act and that each Lothian stockholder will execute and
deliver to the Company, as a condition precedent to the issuance of any Company
securities to such Lothian stockholder in connection with the Merger, a Letter
of Transmittal in the form attached to the Merger Agreement as Exhibit C.

         9. To our knowledge, Section 3.3 of the Merger Agreement and Section
3.3 of the United Disclosure Schedule together correctly set forth the
capitalization of the Company.

         The opinions set forth herein are subject to the following
qualifications:

         A. The enforceability of the Transaction Documents may be limited by
(i) applicable bankruptcy, insolvency, reorganization, arrangement, moratorium,
fraudulent conveyance and other similar state or federal debtor relief laws from
time to time in effect and which affect the enforcement of creditor's rights or
the collection of debtor's obligations in general, (ii) general principles of
equity the application of which may deny Lothian certain of the rights and
remedies granted to it under the Transaction Documents, and (iii) general
principles of commercial reasonableness and good faith to the extent required of
Lothian or its stockholders by applicable law.

         B. We express no opinion concerning any aspect or involvement of any
person or entity other than the Company in the transactions contemplated by the
Transaction Documents.

         For purposes of this opinion, we do not hold ourselves out as experts
in the laws of any jurisdiction other than California and federal laws generally
applicable to transactions of the type involved here.

         In basing the opinions and other matters set forth herein "to our
knowledge," such words signify that, in the course of our representation as
counsel to the Company, no information has come to our attention that has given
us actual knowledge (i.e., conscious awareness) that any such opinions or other
matters are not accurate or that any of the foregoing documents, certificates,
reports and information on which we have relied are not correct and complete. We
have undertaken no independent investigation or verification of such matters.
The words "to our knowledge," and similar language used herein are intended to
be limited to the knowledge of the lawyers within our firm who have worked on
the matters related to the transactions contemplated by the Transaction
Documents.

                                       2

         The opinions in this letter are limited to the matters set forth
herein. No opinion may be inferred or implied beyond the opinions expressly
stated, and our opinions must be read in conjunction with the assumptions,
limitations, exceptions and qualifications set forth in this letter. We assume
no obligation to advise you of any change in facts or law which might come to
our attention subsequent to the date hereof.

         This opinion is being furnished solely for the benefit of Lothian, its
stockholders and its counsel and may not be relied upon by any other person or
entity without our prior written consent.

                                            Yours truly,

Certificate) is true and correct in all material respects on and as of the date
hereof as though such representation or warranty was made on and as of the date
hereof; and each of the representations and warranties made by Lothian in the
Merger Agreement as of a specified date earlier than the date of this Officer's
Certificate is true and correct in all material respects on and as of such

        MATTERS TO BE COVERED BY LEGAL OPINION OF MARKOWITZ & ROSHCO, LLP

United Heritage Corporation
2 North Caddo Street
Cleburne, Texas 76031

Gentlemen:

         We have acted as counsel to Lothian Oil Inc., a Delaware corporation
(the "Company"), in connection with the negotiation, execution and delivery of
the Merger Agreement and Plan of Reorganization, dated as of February ___, 2006
(the "Merger Agreement"; capitalized terms used but not defined herein shall
have the respective meanings ascribed to them in the Merger Agreement), by and
among the Company and United Heritage Corporation, a Utah corporation ("United")
and the Ancillary Agreements to which it is a party (collectively, the
"Transaction Documents").

         For purposes of rendering this opinion, we have limited our examination
to originals or copies, certified or otherwise identified to our satisfaction,
of the following: (i) the Transaction Documents, (ii) the Certificate of
Incorporation and the Bylaws of the Company, (iii) resolutions of the Board of
Directors and of the Stockholders of the Company, and (iv) a certificate of an
officer of the Company. We have assumed the genuiness of all signatures by or on
behalf of persons other than the Company and that all such signatories have been
duly authorized, the authenticity of all documents submitted to us as originals,
and the conformity with originals of all documents submitted to us as certified,
conformed or photostatic copies.

         Based solely upon and in reliance on the foregoing and subject in all
respects to the qualifications, limitations and assumptions set forth herein, it
is our opinion that:

         1. The Company is a corporation duly incorporated and organized,
validly existing and in good standing under the laws of the State of Delaware.

         2. The Company has all necessary corporate power and authority to
execute, deliver and perform its obligations under the Transaction Documents to
which the Company is a party, and the Company has all necessary corporate power
and authority to own its properties and to conduct its business in the manner
and in the locations presently owned and conducted.

         4. The Transaction Documents have been duly authorized, executed and
delivered by the Company, and, assuming due authorization, execution and
delivery by the other parties thereto, each such agreement is a valid and
binding obligation of the Company, enforceable in accordance with its terms.

         5. The execution and delivery by the Company of the Transaction
Documents, and the performance of its obligations thereunder will not (i)
violate the Company's Certificate of Incorporation, the Bylaws of the Company, ,
or to our knowledge, any law, statute, rule or regulation (exclusive of local
laws) applicable to the Company or any order, judgment or decree to which the
Company is subject. To our knowledge, no authorization, consent, approval,
exemption or other action by, or notice to, any court or administrative or

         The opinions set forth herein are subject to the following
qualifications:

         A. The enforceability of the Transaction Documents may be limited by
(i) applicable bankruptcy, insolvency, reorganization, arrangement, moratorium,
fraudulent conveyance and other similar state or federal debtor relief laws from
time to time in effect and which affect the enforcement of creditor's rights or
the collection of debtor's obligations in general, (ii) general principles of
equity the application of which may deny Lothian certain of the rights and
remedies granted to it under the Transaction Documents, and (iii) general
principles of commercial reasonableness and good faith to the extent required of
United by applicable law.

         B. We express no opinion concerning any aspect or involvement of any
person or entity other than the Company in the transactions contemplated by the
Transaction Documents.

         For purposes of this opinion, we do not hold ourselves out as experts
in the laws of any jurisdiction other than New York and federal laws generally
applicable to transactions of the type involved here.

         In basing the opinions and other matters set forth herein "to our

The words "to our knowledge," and similar language used herein are intended to
