Shares and the exercise price for the Warrants in effect immediately prior to
such subdivision shall be proportionately reduced and the number of Newly Issued
Shares to be purchased hereunder and the number of shares of Common Stock
obtainable upon exercise of the Warrants shall be proportionately increased or

one or more classes of its outstanding shares of Common Stock into a smaller
number of shares, the purchase price for the Newly Issued Shares and the
exercise price for the Warrants in effect immediately prior to such combination
shall be proportionately increased and the number of Newly Issued Shares to be

      1.2. SHAREHOLDER APPROVAL REQUIREMENTS. The Parties acknowledge that,
pursuant to sections (i)(1)(B) and (i)(1)(D)(ii) of Rule 4350 of the Nasdaq

Requirements"). The Parties acknowledge that the Company must comply with the
Shareholder Approval Requirements prior to selling the Newly Issued Shares and
issuing the Warrants. The Company's failure to obtain shareholder approval in

Shares it is purchasing, along with the Warrants and the Common Stock underlying
the Warrants, are characterized as "restricted securities" under the federal
securities laws inasmuch as they are being acquired from the Company in a

      3.10 USA PATRIOT ACT REPRESENTATIONS.

            (a) The Investor represents and warrants that the proposed
      investment in the Newly Issued Shares that is being made on its own behalf
      does not directly or indirectly contravene United States federal, state,
      local or international laws or regulations applicable to the Investor,
      including anti-money laundering laws (a "Prohibited Investment").

            (b) Federal regulations and Executive Orders administered by the
      U.S. Treasury Department's Office of Foreign Assets Control ("OFAC")
      prohibit, among other things, the engagement in transactions with, and the
      provision of services to, certain foreign countries, territories, entities
      and individuals. The lists of OFAC prohibited countries, territories,
      persons and entities can be found on the OFAC website at
      www.treas.gov/ofac. The Investor hereby represents and warrants that the
      Investor is not a country, territory, person or entity named on an OFAC
      list, nor is the Investor an entity with whom dealings are prohibited
      under any OFAC regulations.

            (c) The Investor agrees promptly to notify the Company should the
      Investor become aware of any change in the information set forth in this
      Section 3.10. The Investor is advised that, by law, the Company may be
      obligated to "freeze the account" of the Investor, either by prohibiting
      additional capital contributions, declining any withdrawal requests and/or
      segregating the assets in the Investor's account in compliance with
      governmental regulations, and the Company may also be required to report
      such action and to disclose the Investor's identity to OFAC or other
      government agencies.

            (d) The Investor agrees to indemnify and hold harmless the Company,
      its affiliates, their respective directors, officers, members, managers,
      partners, shareholders, employees, agents and representatives (each, an
      "Indemnitee") from and against any and all losses, liabilities, damages,
      penalties, costs, fees and expenses (including legal fees and
      disbursements) (collectively, "Damages") which may result, directly or
      indirectly, from the Investor's misrepresentations or misstatements
      contained herein or breaches hereof.

            (e) The Investor understands and agrees that, notwithstanding
      anything to the contrary contained in any document (including any
      ancillary agreements) if, following the Investor's investment in the Newly
      Issued Shares, it is discovered that the investment is or has become a
      Prohibited Investment, such investment may immediately be redeemed by the
      Company or otherwise be subject to the remedies required by law, and the
      Investor shall have no claim against any Indemnitee for any form of
      Damages as a result of such forced redemption or other action.

            (f) Upon the written request from the Company, the Investor agrees
      to provide all information to the Company to enable the Company to comply
      with all applicable anti-money laundering statutes, rules, regulations and
      policies. The Investor understands and agrees that the Company may release
      confidential information about the Investor to any person if the Company,
      in its sole discretion, determines that such disclosure is necessary to
      comply with applicable statutes, rules, regulations and policies.

officers, directors, employees and agents and each person, if any, who controls
Investor within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act harmless from and against any and all liabilities, losses,
claims, costs, expenses, damages and judgments (including, without limitation,
any legal or other expenses incurred in connection with investigating or
defending any matter, including any action, that could give rise to such
liabilities, losses, claims, costs, expenses, damages and judgments)
(collectively, the "Losses") resulting from or arising out of any breach of any
representation, warranty, or non-performance of any covenant or agreement on the
part of the Company contained in this Agreement or in any statement or
certificate furnished or to be furnished by the Company pursuant hereto or in
connection with the transactions contemplated hereby; and

      7.2 Investor hereby agrees to indemnify and hold the Company, its
officers, directors, employees and agents and each person, if any, who controls
the Company within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act harmless from and against any and all Losses resulting from
or arising out of any breach of any representation, warranty, or non-performance
of any covenant or agreement on the part of Investor contained in this Agreement
or in any statement or certificate furnished or to be furnished by Investor
pursuant hereto or in connection with the transactions contemplated hereby.

      7.3 In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 7.1 or 7.2 (the
"Indemnified Party"), the Indemnified Party shall promptly notify the person
against whom such indemnity may be sought (the "Indemnifying Party") in writing.
A delay in giving notice shall only relieve the Indemnifying Party of liability
to the extent the Indemnifying Party suffers actual prejudice because of the
delay. The Indemnifying Party shall have the right, at its option and expense,
to participate in the defense of such a proceeding or claim, but not to control
the defense, negotiation or settlement thereof, which control shall at all times
rest with the Indemnified Party, unless the proceeding or claim involves only
money damages, not an injunction or other equitable relief, and unless the
Indemnifying Party:

                                       13
<PAGE>

            (a) irrevocably acknowledges in writing complete responsibility for
      and agrees to indemnify the Indemnified Party, and

            (b) furnishes satisfactory evidence of the financial ability to
      indemnify the Indemnified Party,

in which case the Indemnifying Party may assume such control through counsel of
its choice and at its expense, but the Indemnified Party shall continue to have
the right to be represented, at its own expense, by counsel of its choice in
connection with the defense of such a proceeding or claim. If the Indemnifying
Party does not assume control of the defense of such a proceeding or claim, (i)
the entire defense of the proceeding or claim by the Indemnified Party, (ii) any
settlement made by the Indemnified Party, and (iii) any judgment entered in the
proceeding or claim shall be deemed to have been consented to by, and shall be
binding on, the Indemnifying Party as fully as though it alone had assumed the
defense thereof and a judgment had been entered in the proceeding or claim in
the amount of such settlement or judgment, except that the right of the
Indemnifying Party to contest the right of the Indemnified Party to
indemnification under the Agreement with respect to the proceeding or claim
shall not be extinguished. If the Indemnifying Party does assume control of the
defense of such a proceeding or claim, it will not, without the prior written
consent of the Indemnified Party settle the proceeding or claim or consent to
entry of any judgment relating thereto which does not include as an
unconditional term thereof the giving by the claimant to the Indemnified Party a
release from all liability in respect of the proceeding or claim. The Parties
hereto agree to cooperate fully with each other in connection with the defense,
negotiation or settlement of any such proceeding or claim.

8. OTHER CLOSING MATTERS.

      8.1. REPAYMENT OF ALMAC FINANCIAL CORPORATION. Prior to or at the Closing,
Almac Financial Corporation will provide the Escrow Agent with a demand for

breach of this Agreement and does not cure such breach within such 30 days of
receiving detailed written notice thereof, provided that the party seeking to
terminate is not in material breach or default of this Agreement. In the event
of such termination and abandonment, neither the Company nor the Investor (or
any of their respective directors or officers) shall have any liability or
further obligations to any other party to this Agreement, except that nothing
herein will relieve any party from liability for any willful breach of this

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

Date of Issuance: October ____, 2005                       Certificate No. W-___

FOR  VALUE  RECEIVED,  United  Heritage  Corporation,  a Utah  corporation  (the
"Company"),  hereby  grants to LOTHIAN OIL INC. or its  registered  assigns (the
"Registered Holder") the right to purchase from the Company (___________) shares
of Warrant  Stock at a price per share of $________  (as  adjusted  from rime to
time hereunder,  the "Exercise  Price").  This Warrant is issued pursuant to the
terms of that certain Securities Purchase Agreement, dated of even date herewith
(as amended, supplemented or otherwise modified from time to time, the "Purchase
Agreement").  Certain  capitalized  terms used  herein are  defined in Section 3
hereof.  The amount and kind of  securities  obtainable  pursuant  to the rights
granted  hereunder  and the purchase  price for such  securities  are subject to
adjustment pursuant to the provisions contained in this Warrant.

      This Warrant is subject to the following provisions:

      (i) Exercise of Warrant.

1. Exercise Period.  Subject to paragraph lB hereof,  the Registered  Holder may
exercise,  in whole  or in part  (but not as to a  fractional  share of  Warrant
Stock),  the purchase  rights  represented  by this Warrant at any time and from
time to time after the Date of Issuance to and including  the fifth  anniversary
of the Date of Issuance (the "Exercise Period").

2. Exercise Procedure.

            (a) This  Warrant  shall be deemed to have been  exercised  when the
      Company has received all of the following items (the "Exercise Time")

                                       18
<PAGE>

      (a) a completed  Exercise  Agreement,  as described in paragraph lC below,
executed by the Person exercising all or part of the purchase rights represented
by this Warrant (the "Purchaser");

      (b) this Warrant; and

      (c) either (1) a check  payable to the  Company in an amount  equal to the
product  of the  Exercise  Price  multiplied  by the number of shares of Warrant
Stock being purchased upon such exercise (the "Aggregate  Exercise Price"),  (2)
the surrender to the Company of debt or equity  securities of the Company or any
of its  wholly-owned  Subsidiaries  having a Market Price equal to the Aggregate
Exercise Price of the Warrant Stock being purchased upon such exercise (provided
that for  purposes of this  subparagraph,  the Market Price of any note or other
debt  security  or any  preferred  stock  shall  be  deemed  to be  equal to the
aggregate  outstanding  principal  amount or liquidation  value thereof plus all
accrued and unpaid interest  thereon or accrued or declared and unpaid dividends
thereon) or (3) a written notice to the Company that the Purchaser is exercising
the Warrant (or a portion  thereof) by authorizing  the Company to withhold from
issuance a number of shares of Warrant Stock  issuable upon such exercise of the
Warrant which when  multiplied by the Market Price of the Warrant Stock is equal
to the Aggregate  Exercise  Price (and such  withheld  shares shall no longer be
issuable under this Warrant).

            (b) Certificates for shares of Warrant Stock purchased upon exercise
      of this Warrant shall be delivered by the Company to the Purchaser  within
      five  business  days  after the date of the  Exercise  Time.  Unless  this
      Warrant has expired or all of the purchase rights  represented hereby have
      been  exercised,  the Company shall  prepare a new Warrant,  substantially
      identical  hereto,  representing  the rights formerly  represented by this
      Warrant which have not expired or been  exercised  and shall,  within such
      five-day  period,  deliver such new Warrant to the Person  designated  for
      delivery in the Exercise Agreement.

            (c) The Warrant  Stock  issuable  upon the  exercise of this Warrant
      shall be deemed to have been issued to the Purchaser at the Exercise Time,
      and the  Purchaser  shall be deemed for all  purposes  to have  become the
      record holder of such Warrant Stock at the Exercise Time.

            (d) The issuance of  certificates  for shares of Warrant  Stock upon
      exercise of this Warrant  shall be made without  charge to the  Registered
      Holder or the Purchaser  for any issuance tax in respect  thereof or other
      cost  incurred by the Company in  connection  with such  exercise  and the
      related  issuance of shares of Warrant Stock.  Each share of Warrant Stock
      issuable upon exercise of this Warrant shall, upon payment of the Exercise
      Price therefor,  be fully paid and  nonassessable  and free from all liens
      and charges with respect to the issuance thereof.

            (e) The Company  shall not close its books  against the  transfer of
      this Warrant or of any share of Warrant  Stock issued or issuable upon the
      exercise of this  Warrant in any manner which  interferes  with the timely
      exercise of this  Warrant.  The  Company  shall from time to time take all
      such action as may be  necessary to assure that the par value per share of
      the unissued  Warrant Stock acquirable upon exercise of this Warrant is at
      all times equal to or less than the Exercise Price then in effect.

                                       19

            (f) The Company shall at all times reserve and keep available out of
      its authorized but unissued shares of Common Stock, solely for the purpose
      of issuance  upon the exercise of this  Warrant,  such number of shares of
      Warrant  Stock  issuable  upon the exercise of this  Warrant.  The Company
      shall take all such  actions as may be  necessary  to assure that all such
      shares  of  Warrant  Stock  may  be so  issued  without  violation  of any
      applicable  law or  governmental  regulation  or any  requirements  of any
      domestic  securities  exchange  upon which shares of Warrant  Stock may be
      listed (except for official  notice of issuance which shall be immediately
      delivered by the Company upon each such  issuance).  The Company shall not
      take any action  which would cause the number of  authorized  but unissued
      shares of Warrant Stock to be less than the number of such shares required
      to be reserved hereunder for issuance upon exercise of this Warrant.

3. Exercise Agreement. Upon any exercise of this Warrant, the Exercise Agreement
shall be substantially  in the form set forth in Annex I hereto,  except that if
the  shares of  Warrant  Stock are not to be issued in the name of the Person in
whose name this Warrant is registered,  the Exercise  Agreement shall also state
the name of the Person to whom the  certificates for the shares of Warrant Stock
are to be issued, and if the number of shares of Warrant Stock to be issued does
not include all the shares of Warrant Stock purchasable hereunder, it shall also
state the name of the Person to whom a new Warrant for the  unexercised  portion
of the rights  hereunder is to be delivered.  Such Exercise  Agreement  shall be
dated the actual date of execution thereof.

4. Fractional  Shares. If a fractional share of Warrant Stock would, but for the
provisions of paragraph 1A, be issuable upon exercise of the rights  represented
by this Warrant,  the Company shall, within five business days after the date of
the Exercise Time,  deliver to the Purchaser a check payable to the Purchaser in
lieu of such fractional  share in an amount equal to the difference  between the
Market Price of such  fractional  share as of the date of the Exercise  Time and
the Exercise Price of such fractional share.

5. Restrictive  Legend.  Unless  registered under the Securities Act of 1933, as
amended (the "Act"),  each certificate for Warrant Stock purchased upon exercise
of this Warrant shall bear a legend as follows:

THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES  ACT OF 1933, AS AMENDED (THE "ACT") OR APPLICABLE  STATE LAW AND
MAY  NOT  BE  OFFERED  FOR  SALE,  SOLD  OR  OTHERWISE  TRANSFERRED  PLEDGED  OR
HYPOTHECATED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT WITH RESPECT
TO SUCH  SECURITIES,  OR DELIVERY OF AN OPINION OF COUNSEL IN FORM AND SUBSTANCE
SATISFACTORY  TO THE  ISSUER  OF  THESE  SECURITIES  THAT  SUCH  OFFER,  SALE OR
TRANSFER,  PLEDGE OR HYPOTHECATION  IS EXEMPT FROM  REGISTRATION OR OTHERWISE IN
COMPLIANCE WITH THE ACT AND APPLICABLE STATE LAW.

      (ii) Adjustment of Exercise Price and Number of Shares. The Exercise Price
shall be subject to adjustment  from time to time as provided in this Section 2,
and the number of shares of  Warrant  Stock  obtainable  upon  exercise  of this
Warrant  shall be subject to  adjustment  from time to time as  provided in this
Section 2.

1.  Subdivision  or  Combination  of Common  Stock.  If the  Company at any time
subdivides (by any stock split, stock dividend,  recapitalization  or otherwise)
one or more  classes of its  outstanding  shares of Common  Stock into a greater
number  of  shares,  the  Exercise  Price in  effect  immediately  prior to such
subdivision shall be proportionately reduced and the number of shares of Warrant
Stock  obtainable  upon  exercise  of  this  Warrant  shall  be  proportionately
increased.  If the  Company at any time  combines  (by  reverse  stock  split or
otherwise) one or more classes of its outstanding  shares of Common Stock into a
smaller number of shares, the Exercise Price in effect immediately prior to such
combination  shall be  proportionately  increased  and the  number  of shares of
Warrant Stock obtainable upon exercise of this Warrant shall be  proportionately
decreased.

2. Notices. Promptly following any adjustment of the Exercise Price, the Company
shall give written  notice thereof to the  Registered  Holder,  setting forth in
reasonable detail and certifying the calculation of such adjustment.

      (iii) Definitions. The following terms have meanings set forth below:

            "Common Stock" means,  collectively,  the Company's Common Stock and
any capital stock of any class of the Company hereafter  authorized which is not
limited to a fixed sum or  percentage  of par or stated  value in respect to the
rights of the holders thereof to participate in dividends or in the distribution
of assets upon any liquidation, dissolution or winding up of the Company.

            "Market  Price"  means as to any security the average of the closing
prices of such security's  sales on all domestic  securities  exchanges on which
such security may at the time be listed,  or, if there have 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, on such day, 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 21 days
consisting of the day as of which "Market Price" is being  determined and the 20
consecutive  business days prior to such day;  provided that if such security is
listed on any domestic  securities  exchange the term "business days" as used in
this sentence means business days on which such exchange is open for trading. If
at any time such security is not listed on any domestic  securities  exchange or
quoted in the NASDAQ System or the domestic over-the-counter market, the "Market
Price" shall be the fair value thereof determined jointly by the Company and the
Registered Holders;  provided that if such parties are unable to reach agreement
within a reasonable  period of time,  such fair value shall be  determined by an
appraiser  selected by the Company and approved by the  Registered  Holder (such
approval not to be unreasonably  withheld).  The determination of such appraiser
shall be final and  binding on the Company and the  Registered  Holder,  and the
fees and expenses of such appraiser shall be paid by the Company.

                                       21
<PAGE>

            "Person" means an  individual,  a  partnership,  a joint venture,  a
corporation,   a  limited   liability   company,   a  trust,  an  unincorporated
organization and a government or any department or agency thereof.

            "Warrant Stock" means the Company's  Common Stock,  par value $0.001
per share.

            Other  capitalized terms used in this Warrant but not defined herein
shall have the meanings set forth in the Purchase  Agreement.

      (iv) Registration Rights.

1. "Piggy-Back"  Registration.  The Registered Holder of this Warrant shall have
the  right to  include  all or any  portion  of this  Warrant  requested  by the
Registered Holder and all of the securities  underlying such Warrant,  including
the Warrant  Stock  underlying  this  Warrant  (collectively,  the  "Registrable
Securities"),  as part of any registration statement proposed to be filed by the
Company  with  the  Securities  and  Exchange  Commission  for  the  purpose  of
registering any of its Common Stock for its own or its officers', directors', or
shareholders'  accounts under the Act for a public offering for cash (other than
in connection with a transaction  contemplated by Rule 145(a)  promulgated under
the Act or pursuant to Form S-8); provided that this Warrant has been exercised,
or is exercisable prior to the closing of such registration.

2.  Terms.  The  Company  shall  bear  all  fees  and  expenses  attendant  upon
registering the Registrable Securities,  but the Registered Holder shall pay any
and all underwriting  commissions and the expenses of any legal counsel selected
by the  Registered  Holder to  represent it in  connection  with the sale of the
Registrable  Securities.  In the  event  of such a  proposed  registration,  the
Company  shall  furnish  the  Registered   Holder  of  outstanding   Registrable
Securities with not less than forty-five (45) days' written notice thereof prior
to the proposed date of filing of such  registration  statement.  Such notice to
the Registered Holder shall continue to be given for each registration statement
filed by the Company until such time as all of the  Registrable  Securities have
been  registered.  The Registered  Holder of the  Registrable  Securities  shall
exercise the  "piggy-back"  rights provided for herein by giving written notice,
within thirty (30) days of the receipt of the Company's  notice of its intention
to file a registration  statement.  The Company shall have the absolute right to
withdraw or cease to prepare or file any registration statement for any offering
referred  to in this  Section 5  without  any  obligation  or  liability  to any
Registered Holder.

3. Reduction in Registration  Rights.  Notwithstanding 5B above, if any managing
underwriter  of the  securities  being  offered  pursuant  to  any  registration
statement  under this  Section 4 advises  the  Company in writing  that,  in its
opinion, the number of shares to be sold by persons other than the Company would
materially and adversely affect such offering,  or the timing thereof,  then the
Company shall reduce,  pro rata (based upon the number of shares requested to be
included by the Company's  officers',  directors',  shareholders'  and all other
securities  sought to be  registered  pursuant to the  exercise  of  contractual
rights  comparable  to the  rights  granted  in this  Section  5) the  number of
Registrable  Securities  to  a  number  deemed  satisfactory  by  such  managing
underwriter.

                                       22
<PAGE>

4. Lock-up. Further in the event that any managing underwriter of the securities
being  offered  pursuant  to any  registration  statement  under this  Section 5
requires,  as a condition of including for registration  shares belonging to the
Company's officers, directors,  shareholders,  that such officers, directors and
shareholders agree to delay the offering and sale of such registered  securities
for a period of time (the "Lock-Up Period"),  the Registered Holder hereof shall
agree to such Lock-Up  Period,  provided  that such Lock-Up be on the same terms
and  conditions  as  that  of  the  Company's  officers,   directors  and  other
shareholders.

5. Limitations. Each Registered Holder shall be entitled to have its Registrable
Securities included in up to three (3) piggy-back registrations pursuant to this
Section  5,  provided  that,  if all  of  the  Registrable  Securities  are  not
registered  due to the  provisions  of Section 5C hereof,  then the  limitations
contained herein shall not be effective.

6. Indemnification.

            (i)  In  the  event  of any  registration  of any of the  Registered
Holder's  Registrable  Securities  under  this  Section  5,  the  Company  shall
indemnify and hold  harmless the  Registered  Holder,  the  Registered  Holder's
directors,  officers,  and each entity or person  controlling  Registered Holder
within the meaning of Section 15 of the Securities  Act, if any, with respect to
which such registration,  qualification or compliance has been effected pursuant
to this Section 5, and each  underwriter,  if any, and each entity or person who
controls any underwriter within the meaning of Section 15 of the Securities Act,
against all expenses,  claims,  losses,  damages and  liabilities (or actions in
respect thereof),  including any of the foregoing  incurred in settlement of any
litigation,  commenced  or  threatened,  arising  out of or based on any  untrue
statement (or alleged  untrue  statement)  of a material  fact  contained in any
registration statement,  prospectus, offering circular or other document, or any
amendment   or   supplement   thereto,   incident  to  any  such   registration,
qualification or compliance,  or based on any omission (or alleged  omission) to
state therein a material fact required to be stated therein or necessary to make
the statements  therein,  in light of the circumstances in which they were made,
not  misleading,  or  any  violation  by  Company  of  any  rule  or  regulation
promulgated  under the  Securities  Act  applicable  to Company and  relating to
action or inaction required of Company in connection with any such Registration,
qualification  or compliance,  and shall reimburse  Registered  Holder,  each of
Registered Holder's directors,  officers,  employees and agents, and each entity
or person controlling  Registered Holder,  each such underwriter and each entity
or  person  who  controls  any such  underwriter,  for any  legal  and any other
expenses  reasonably  incurred in connection  with  investigating,  preparing or
defending  any such claim,  loss,  damage,  liability or action,  provided  that
Company shall not be liable to Registered  Holder or an  underwriter in any such
case to the extent  that any such  claim,  loss,  damage,  liability  or expense
arises out of or is based solely on any untrue  statement or omission or alleged
untrue  statement  or omission  made in  reliance  upon and in  conformity  with
written  information  furnished  to Company by an  instrument  duly  executed by
Registered  Holder  or an  underwriter  and  stated to be  specifically  for use
therein.

                                       23
<PAGE>

            (ii) Registered Holder shall, if Registrable Securities are included
in the securities as to which a  Registration,  qualification  or compliance has
been  effected  pursuant  to this  Section  5,  indemnify  Company,  each of its
directors  and  officers,  each  underwriter,  if any, of  Company's  securities
covered by such registration, qualification or compliance, each entity or person
who controls Company or such underwriter within the meaning of Section 15 of the
Securities  Act,  and each of its  directors,  officers,  employees  and agents,
against all expenses,  claims,  losses,  damages and  liabilities (or actions in
respect thereof),  including any of the foregoing  incurred in settlement of any
litigation  commenced  or  threatened,  arising  out of or based  on any  untrue
statement (or alleged  untrue  statement)  of a material  fact  contained in any
registration statement,  prospectus, offering circular or other document, or any
amendment   or   supplement   thereto,   incident  to  any  such   Registration,
qualification  or compliance  or based on any omission (or alleged  omission) to
state therein a material fact required to be stated therein or necessary to make
the statements  therein,  in the light of the  circumstances  in which they were
made,  not  misleading,  or any  violation by Company of any rule or  regulation
promulgated  under the Securities  Act applicable to Company in connection  with
any  such  Registration,  qualification,  or  compliance,  and  shall  reimburse
Company, such directors,  officers,  employees,  agents, underwriters or control
persons for any legal or any other  expenses  reasonably  incurred in connection
with  investigating,  preparing  or  defending  any such  claim,  loss,  damage,
liability or action,  in each case to the extent,  but only to the extent,  that
such untrue  statement  (or alleged  untrue  statement)  or omission (or alleged
omission) is made in such registration statement,  prospectus, offering circular
or other document or any amendment or supplement thereto in reliance upon and in
conformity with written  information  furnished to Company by an instrument duly
executed by  Registered  Holder and stated to be  specifically  for use therein;
provided,  however,  that  Registered  Holder's  obligations  hereunder shall be
limited to an amount equal to the proceeds Registered Holder received for Shares
sold as contemplated herein.

            (iii) Each party entitled to indemnification under this section (the
"Indemnified  Party")  shall  give  notice  to the  party  required  to  provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the  Indemnifying  Party to assume  the  defense of any such claim or any
litigation  resulting  therefrom,  provided  that  counsel for the  Indemnifying
Party,  who shall  conduct  the  defense of such claim or  litigation,  shall be
approved by the  Indemnified  Party (whose  approval  shall not be  unreasonably
withheld),  and the Indemnified Party may participate in such defense at its own
expense,  and provided further that the failure of any Indemnified Party to give
notice as  provided  herein  shall not  relieve  the  Indemnifying  Party of its
obligations  under this section unless such failure resulted in actual detriment
to the  Indemnifying  Party. No  Indemnifying  Party, in the defense of any such
claim or litigation,  shall,  except with the consent of each Indemnified Party,
consent to entry of any  judgment  or enter into any  settlement  which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified  Party a release from all liability in respect of such claim
or litigation.

            (iv) If the indemnification  provided for in this section is held by
a court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss,  liability,  claim, damage, or expense referred to therein,
then the  Indemnifying  Party, in lieu of indemnifying  such  Indemnified  Party
hereunder,  shall  contribute to the amount paid or payable by such  Indemnified
Party as a result of such loss,  liability,  claim,  damage,  or expense in such
proportion as is appropriate  to reflect the relative fault of the  Indemnifying
Party on the one hand and of the  Indemnified  Party on the other in  connection
with the statements or omissions that resulted in such loss,  liability,  claim,
damage, or expense, as well as any other relevant equitable considerations.  The
relative fault of the Indemnifying  Party and of the Indemnified  Party shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue  statement of a material  fact or the  omission to state a material  fact
relates to information  supplied by the Indemnifying Party or by the Indemnified
Party and the parties' relative intent,  knowledge,  access to information,  and
opportunity to correct or prevent such statement or omission

                                       24

7. No Voting Rights; Limitations of Liability.  Except as otherwise set forth in
this  Warrant,  this Warrant  shall not entitle the holder  hereof to any voting
rights or other rights as a stockholder of the Company.  No provision hereof, in
the absence of affirmative  action by the Registered  Holder to purchase Warrant
Stock,  and no enumeration  herein of the rights or privileges of the Registered
Holder shall give rise to any liability of such holder for the Exercise Price of
Warrant Stock acquirable by exercise hereof or as a stockholder of the Company.

8. Transfers,  etc. Subject to the transfer conditions referred to in the legend
endorsed  hereon,  this Warrant and all rights  hereunder are  transferable,  in

this  Warrant  with a  properly  executed  Assignment  (in the  form of Annex II
hereto) at the principal office of the Company.

9.  Warrant   Exchangeable   for  Different   Denominations.   This  Warrant  is
exchangeable,  upon  the  surrender  hereof  by  the  Registered  Holder  at the
principal office of the Company,  for new Warrants of like tenor representing in
the aggregate the purchase rights hereunder, and each of such new Warrants shall
represent such portion of such rights as is designated by the Registered  Holder
at the time of such  surrender.  The  date the  Company  initially  issues  this
Warrant  shall be deemed to be the "Date of Issuance"  hereof  regardless of the
number of times new  certificates  representing  the unexpired  and  unexercised
rights  formerly  represented  by this  Warrant  shall be issued.  All  Warrants
representing  portions  of the rights  hereunder  are  referred to herein as the
"Warrants."

10. Replacement. Upon receipt of evidence reasonably satisfactory to the Company
(an affidavit of the Registered  Holder shall be  satisfactory) of the ownership
and the loss,  theft,  destruction or mutilation of any  certificate  evidencing
this  Warrant,  and in the case of any such  loss,  theft or  destruction,  upon
receipt of indemnity  reasonably  satisfactory to the Company  (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 Company shall (at its expense)  execute and
deliver in lieu of such certificate a new certificate of like kind  representing
the same  rights  represented  by such  lost;  stolen,  destroyed  or  mutilated
certificate  and dated the date of such lost,  stolen,  destroyed  or  mutilated
certificate.

11. Notices. Except as otherwise expressly provided herein, all notices referred
to in this Warrant shall be in writing and shall be delivered personally or sent
by reputable  overnight courier service (charges prepaid) and shall be deemed to
have been given when so delivered or sent (i) to the Company,  at its  principal
executive  offices and (ii) to the  Registered  Holder of this Warrant,  at such
holder's  address as it appears in the records of the Company (unless  otherwise
indicated by any such holder).

12. Amendment and Waiver. Except as otherwise provided herein, the provisions of
this Warrant may be amended by the Company in any manner that does not adversely
affect the right of the  Registered  Holder.  The provisions of this Warrant may
also be amended and the Company may take any action herein  prohibited,  or omit
to perform any act herein  required to be  performed  by it, only if the Company
has obtained the written consent of the Registered Holder.

13.  Descriptive  Headings;  Governing  Law. THE  CORPORATE LAW OF THE COMPANY'S
STATE OF  INCORPORATION  SHALL GOVERN ALL ISSUES AND  QUESTIONS  CONCERNING  THE
RELATIVE RIGHTS AND OBLIGATIONS OF THE COMPANY AND ITS  STOCKHOLDERS.  ALL OTHER
ISSUES AND QUESTIONS  CONCERNING THE  CONSTRUCTION,  VALIDITY,  ENFORCEMENT  AND
INTERPRETATION OF THIS WARRANT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF TEXAS, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW
OR  CONFLICT  OF LAW RULES OR  PROVISIONS  (WHETHER OF THE STATE OF TEXAS OR ANY
OTHER  JURISDICTION)  THAT WOULD CAUSE THE  APPLICATION OF THE LAWS OF ANY OTHER
JURISDICTION OTHER THAN THE STATE OF TEXAS.

      THIS SECURITIES PURCHASE AGREEMENT is made as of the 7th day of October
2005 by and between_____________________(collectively, the "Selling
Shareholders") and Lothian Oil Inc., a Delaware corporation (the "Investor").

         WHEREAS, the Investor has indicated a desire to purchase shares of the
common stock, par value $0.001 per share (the "Common Stock"), of United
Heritage Corporation (the "Company") pursuant to the terms of this Agreement.

         WHEREAS, the Selling Shareholders have indicated a desire to sell their
shares of the Company's Common Stock to the Investor on the terms set forth
herein.

         WHEREAS, the Selling Shareholders and the Investor have agreed that
this Agreement shall constitute the entire understanding and agreement among the
parties with regard to the subject matter hereof.

         THEREFORE the Selling Shareholders and the Investor (collectively
sometimes referred to as the Parties) agree as follows:

1. PURCHASE AND SALE OF SECURITIES.

      1.1. SALE OF SECURITIES BY THE SELLING SHAREHOLDERS. Subject to the terms
and conditions of this Agreement, the Selling Shareholders agree to sell to the
Investor and the Investor agrees to purchase from the Selling Shareholders a
total of 8,000,000 shares of the Company's Common Stock (the "Selling
Shareholders' Shares") for an aggregate purchase price of $10,651,000 or
$1.331375 per share. The purchase price for the Selling Shareholders' Shares
shall be made with a promissory note (the "Note") in substantially the form
attached to this Agreement as Exhibit A. The Note shall be secured by a pledge
of the Selling Shareholders' Shares, which pledge shall be memorialized in a
Stock Pledge Agreement in substantially the form attached to this Agreement as
Exhibit B. The purchase price for the Selling Shareholders' Shares and the
number of Selling Shareholders' Shares to be purchased hereunder shall be
subject to adjustment if the Company (i) at any time subdivides (by any stock
split, stock dividend, recapitalization or otherwise) one or more classes of its
outstanding shares of Common Stock into a greater number of shares, the purchase
price for the Common Stock in effect immediately prior to such subdivision shall
be proportionately reduced and the number of Selling Shareholders' Shares to be
purchased hereunder shall be proportionately increased or (ii) if the Company at
any time combines (by reverse stock split or otherwise) one or more classes of
its outstanding shares of Common Stock into a smaller number of shares, the
purchase price for the Selling Shareholders' Shares in effect immediately prior
to such combination shall be proportionately increased and the number of Selling
Shareholders' Shares to be purchased hereunder shall be proportionately
decreased.

<PAGE>

      The Selling Shareholders hereby irrevocably appoint Walter G. Mize as
their "Agent" as such term is used in the Note and "Pledgeholder" as such term
is used in the Stock Pledge Agreement.

      1.2. ESCROW. At the Closing, the Parties will open an escrow account at
Community Bank (the "Escrow Agent"), Account Number: 003-7575, 500 S. Morgan
Street, Granbury, Texas. 76048, Attn: Mr. Jimmy Campbell, telephone: (817)
573-5902, and within three business days of opening the escrow account the
Investor will deposit with the Escrow Agent good and immediately available funds
totaling $3,500,000 (the "Escrowed Funds") pursuant to the terms of the Escrow
Agreement attached hereto as Exhibit C (the "Escrow Agreement"). The Escrow
Agreement shall provide, inter alia, for the Escrowed Funds to be released by
the Escrow Agent to the Selling Shareholders, in accordance with their
instruction, promptly following approval by the Company's shareholders of the
sale of 3,280,000 shares of Common Stock and warrants to purchase an additional
8,720,000 shares of Common Stock to the Investor in accordance with the terms of
that certain letter of intent dated August 9, 2005 and entered into by the
Investor and the Company on August 10, 2005 ("Shareholder Approval") and the
consummation of the transactions contemplated thereby (the "Company Issuance").
The Selling Shareholders shall apply the Escrowed Funds to the principal balance
of the Note in accordance with the terms thereof. In the event that Shareholder
Approval and the Company Issuance shall not have occurred as of January 31,
2006, and upon the exercise of the Investor Put Option set forth in Section 1.4
below, the Escrow Agreement shall provide that the Escrowed Funds be promptly
returned to the Investor.

      1.3. THE CLOSING. The closing of the purchase and sale of the Selling
Shareholders' Shares (the "Closing") shall be held concurrently with the
execution and delivery of this Agreement, subject to the satisfaction or waiver
of the closing conditions set forth in Sections 4 and 5 hereof, or such later
date as the Investor and the Selling Shareholders may agree upon (the "Closing
Date").

      1.4 INVESTOR PUT OPTION. In the event that Shareholder Approval and the
Company Issuance have not occurred as of January 31, 2006, the Investor may
require the Selling Shareholders to repurchase the Selling Shareholder Shares in
exchange for cancellation of the outstanding principal amount of the Note and
all accrued and unpaid interest thereon, in which event the Parties shall
instruct the Escrow Agent to transfer the Escrowed Funds to the Investor and
terminate the escrow.

2. REPRESENTATIONS AND WARRANTIES OF THE INVESTOR. The Investor hereby
represents and warrants that:

      2.1. ORGANIZATION, GOOD STANDING, POWER AND RIGHTS TO ACQUIRE STOCK. The
Investor is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware and has all requisite corporate power
and authority to enter into the transaction contemplated by this Agreement. The
Investor is duly qualified or licensed as a foreign corporation to do business,
and is in good standing, in each jurisdiction where the character of the
properties or assets owned, leased or operated by it or the nature of its
activities makes such qualification or licensing necessary.

                                       2
<PAGE>

      2.2. AUTHORIZATION. The Investor has full right, power and authority to
execute and deliver this Agreement, to perform its obligations hereunder and to
consummate the transactions contemplated by this Agreement. To the extent
applicable, this Agreement and the transactions contemplated by this Agreement
have been duly and validly authorized by the Investor. This Agreement has been
duly and validly executed and delivered by the Investor and constitutes valid
and legally binding obligations of the Investor enforceable in accordance with
its terms, subject to laws of general application relating to bankruptcy,
insolvency and the relief of debtors and by general principles of equity.

      2.3. INVESTIGATION. The Investor acknowledges that it has had an
opportunity to discuss the business and affairs of the Company with the
Company's President, Walter G. Mize. The Investor further acknowledges having
had access to information about the Company that it has requested or considers
necessary for purposes of purchasing the Selling Shareholders' Shares, including
documents filed by the Company with the Securities and Exchange Commission and
the exhibits thereto (the "Company's SEC Documents").

      2.4. ACCREDITED INVESTOR. The Investor is an "Accredited Investor" as such
term is defined in Regulation D adopted by the SEC.

      2.5. PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made with the
Investor in reliance upon the Investor's representation, which by the Investor's
execution of this Agreement the Investor hereby confirms, that the Selling
Shareholders' Shares will be acquired for investment for the Investor's own
account, not as a nominee or agent, and not with a view to the resale or
distribution of any part thereof other than in conformity with the Act and the
rules and regulations promulgated thereunder, and that the Investor has no
present intention of selling, granting any participation in, or otherwise
distributing the same, other than a transfer to a nominee holder or a
majority-owned affiliate.

      2.6. RESTRICTED SECURITIES. The Investor understands that the Selling
Shareholders' Shares are characterized as "restricted securities" under the
federal securities laws inasmuch as they are being acquired from the Selling
Shareholders who acquired them from the Company in a transaction not involving a
public offering and that under such laws and applicable regulations such
securities may be resold without registration under the Act only in certain
limited circumstances. In this connection, the Investor represents that it is
familiar with Rule 144 promulgated by the Securities and Exchange Commission, as
presently in effect, and understands the resale limitations imposed thereby and
by the Act. For purposes of this Agreement, an affiliate of the Investor shall
be deemed to be an entity controlling, controlled by or under common control
with the Investor, where control is evidenced by the ownership of 100% of an
entity.

                                       3

      2.7. AUTHORIZATIONS. All authorizations, approvals or permits, if any, of
any governmental authority or regulatory body that are required to be obtained
by the Investor in connection with the lawful purchase and sale of the Selling
Shareholders' Shares pursuant to this Agreement have been duly obtained and
shall be effective on and as of the Closing.

      2.8. BROKER'S OR FINDERS' FEE. The Investor has not incurred, nor will it
incur, directly or indirectly, any liability for brokerage or finders' fees or
agents' commissions or investment bankers' fees or any similar charges that will
be chargeable against the Selling Shareholders in connection with the
transaction contemplated by this Agreement.

      2.9. LEGENDS. It is understood that the certificates evidencing the
Selling Shareholders' Shares may bear a legend in substantially the following
form:

      "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
      1933, AS AMENDED (THE "ACT"). THEY MAY NOT BE SOLD, OFFERED FOR SALE,
      PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN
      EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF
      COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT
      REQUIRED UNDER THE ACT."

      2.10 USA PATRIOT ACT REPRESENTATIONS.

            (a) The Investor represents and warrants that the proposed
      investment in the Selling Shareholders' Shares that is being made on its
      own behalf does not directly or indirectly contravene United States
      federal, state, local or international laws or regulations applicable to
      the Investor, including anti-money laundering laws (a "Prohibited
      Investment").

            (b) Federal regulations and Executive Orders administered by the
      U.S. Treasury Department's Office of Foreign Assets Control ("OFAC")
      prohibit, among other things, the engagement in transactions with, and the
      provision of services to, certain foreign countries, territories, entities
      and individuals. The lists of OFAC prohibited countries, territories,
      persons and entities can be found on the OFAC website at
      www.treas.gov/ofac. The Investor hereby represents and warrants that the
      Investor is not a country, territory, person or entity named on an OFAC
      list, nor is the Investor an entity with whom dealings are prohibited
      under any OFAC regulations.

      Shareholders, their agents and representatives (each, an "Indemnitee")
      from and against any and all losses, liabilities, damages, penalties,
      costs, fees and expenses (including legal fees and disbursements)
      (collectively, "Damages") which may result, directly or indirectly, from
      the Investor's misrepresentations or misstatements contained herein or
      breaches hereof.

            (e) The Investor understands and agrees that, notwithstanding
      anything to the contrary contained in any document (including any
      ancillary agreements) if, following the Investor's investment in the
      Selling Shareholders' Shares, it is discovered that the investment is or
      has become a Prohibited Investment, such investment may immediately be
      redeemed by the Selling Shareholders or otherwise be subject to the
      remedies required by law, and the Investor shall have no claim against any
      Indemnitee for any form of Damages as a result of such forced redemption
      or other action.

Investor within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act harmless from and against any and all liabilities, losses,
claims, costs, expenses, damages and judgments (including, without limitation,
any legal or other expenses incurred in connection with investigating or
defending any matter, including any action, that could give rise to such
liabilities, losses, claims, costs, expenses, damages and judgments)
(collectively, the "Losses") resulting from or arising out of any breach of any
representation, warranty, or non-performance of any covenant or agreement on the
part of the Selling Shareholders contained in this Agreement or in any statement
or certificate furnished or to be furnished by the Selling Shareholders pursuant
hereto or in connection with the transactions contemplated hereby; and

      6.2 The Investor hereby agrees to indemnify and hold the Selling
Shareholders and their respective successors and assigns harmless from and
against any and all Losses resulting from or arising out of any breach of any
representation, warranty, or non-performance of any covenant or agreement on the
part of Investor contained in this Agreement or in any statement or certificate
furnished or to be furnished by Investor pursuant hereto or in connection with
the transactions contemplated hereby.

      6.3 In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 7.1 or 7.2 (the
"Indemnified Party"), the Indemnified Party shall promptly notify the person
against whom such indemnity may be sought (the "Indemnifying Party") in writing.
A delay in giving notice shall only relieve the Indemnifying Party of liability
to the extent the Indemnifying Party suffers actual prejudice because of the
delay. The Indemnifying Party shall have the right, at its option and expense,
to participate in the defense of such a proceeding or claim, but not to control
the defense, negotiation or settlement thereof, which control shall at all times
rest with the Indemnified Party, unless the proceeding or claim involves only
money damages, not an injunction or other equitable relief, and unless the
Indemnifying Party:

                                       8
<PAGE>

            (a) irrevocably acknowledges in writing complete responsibility for
      and agrees to indemnify the Indemnified Party, and

            (b) furnishes satisfactory evidence of the financial ability to
      indemnify the Indemnified Party,

in which case the Indemnifying Party may assume such control through counsel of
its choice and at its expense, but the Indemnified Party shall continue to have
the right to be represented, at its own expense, by counsel of its choice in
connection with the defense of such a proceeding or claim. If the Indemnifying
Party does not assume control of the defense of such a proceeding or claim, (i)
the entire defense of the proceeding or claim by the Indemnified Party, (ii) any
settlement made by the Indemnified Party, and (iii) any judgment entered in the
proceeding or claim shall be deemed to have been consented to by, and shall be
binding on, the Indemnifying Party as fully as though it alone had assumed the

exceeds the unpaid balance of the Principal Amount under this Note, such excess
shall be refunded to Maker. This provision shall control every other provision
of all agreements between Maker and Holders.

      16. Governing Law and Jurisdiction.

      This Note shall be governed by, interpreted under and construed and
enforced in accordance with the laws of the State of Texas. Any action to

            as required by Section 2(b) of the Note, the Pledgeholder shall
            deliver 2,800,000 shares of the Pledged Shares, and any Proceeds
            attributable to that portion of the Pledged Shares, to the Borrower;

                  (ii) Upon payment of $2,383,666 plus accrued interest, if any,
            as required by Section 2(c) of the Note, the Pledgeholder shall
            deliver 1,733,333 shares of the Pledged Shares, and any Proceeds
            attributable to that portion of the Pledged Shares, to the Borrower;
            and

                  (iii) Upon payment of the full unpaid principal balance owing
            on the Note, plus all accrued, unpaid interest, the Pledgeholder
            shall deliver 3,466,667 shares of the Pledged Shares, and any
            Proceeds attributable to that portion of the Pledged Shares, to the
            Borrower.

            (f) As used in this Agreement, the term "Indebtedness" means the
indebtedness evidenced by the Note, including all principal and accrued interest
thereon, together with all other liabilities, costs, and expenses for which
Pledgor is responsible under this Agreement, including collection costs and
attorneys fees, and all renewals, extensions, modifications, substitutions, and
rearrangements of any of the foregoing.

                                       20
<PAGE>

         All of the Pledged Shares, and any Proceeds attributable to that
portion of the Pledged Shares, when released by the Pledgeholder to the
Borrower, shall be free of any lien or encumbrance.

      2. Matters Pertaining to the Collateral.

            (a) Voting and Consensual Rights. Pledgor shall retain the right to
vote the Pledged Shares and to exercise any other rights pertaining to the
Pledged Shares, provided, however, so long as Pledgor is in "Default" as defined
in Paragraph 3 of this Agreement, Secured Parties shall vote the Pledged Shares
and exercise any rights pertaining to the Pledged Shares.

            (b) Rights to Dividends and Distributions. So long as Pledgor is not
in Default and except as expressly limited below, Pledgor shall be entitled to
receive and retain any Proceeds distributed on account of the Pledged Shares.
Notwithstanding the foregoing, Secured Parties, rather than Pledgor, shall be
entitled to collect and receive all of the following types of Proceeds, which
shall be added to and shall become a part of the Collateral:

            (i) all proceeds paid or payable other than in cash, and all
instruments and other property distributed in respect of, or in exchange for,
the Pledged Shares;

            (ii) all proceeds paid or payable with respect to the Pledged Shares
in connection with a partial or total liquidation or dissolution of United
Heritage Corporation (the "Company") or in connection with a reduction of
capital, capital surplus or paid-in surplus of the Company; and

            (iii) all proceeds distributed in redemption of, or in exchange for,
the Pledged Shares. To the extent the foregoing proceeds exceed the amount of
Pledgor's obligations and liabilities under the Note and/or this Agreement,
Pledgor shall be entitled to receive these excess proceeds.

      In the event and for so long as Pledgor is in Default as defined in
Section 3 below, Secured Parties shall receive all Proceeds with respect to the
Pledged Shares for immediate application to the Note.

      (c) Stock Adjustments. In the event that, during the term of this
Agreement, any stock dividend, reclassification, readjustment, or other change
is declared or made in the capital structure of the Company, all new,
substituted and additional shares or other securities issued with respect to the
Pledged Shares by reason of any such change shall be delivered to and held by
the Pledgeholder for the benefit of the Secured Parties under the terms of this
Agreement in the same manner as the Pledged Shares.

                                       21

      3. Default and Remedy on Default.

            (a) The occurrence of any of the following shall constitute an event
of default ("Default") under this Agreement:

                  (i) Default Under Note. If an Event of Default, as set forth
            in Section 9 of the Note, occurs and is not cured as specifically
            provided therein, or

                  (ii) Default Under This Agreement. If Pledgor defaults in the
            due performance or observance of any representation or obligation
            under the Note or this Agreement, or

                  (iii) Bankruptcy of the Company. The Company files a petition
            for relief under the Bankruptcy Code, an involuntary petition for
            relief is filed against the Company under the Bankruptcy Code and
            such involuntary petition is not dismissed within thirty (30) days
            after the filing thereof, or an order for relief naming the Company
            is entered under the Bankruptcy Code; or

            (b) At the option of Secured Parties, upon the happening and during
the continuance of any Default, Secured Parties shall have all of the rights and
remedies set forth below:

            (i) if Secured Parties so elect and give notice of such election to
Pledgor, the Pledgeholder may vote any or all shares of the Pledged Shares as
proxy for Pledgor and Secured Parties, for any lawful purpose and give all
consents, waivers and ratifications in respect of the Pledged Shares and
otherwise act on behalf of the Secured Parties with respect thereto as though
the Secured Parties were the outright owners thereof (Pledgor hereby irrevocably
constituting and appointing the Pledgeholder the proxy and attorney-in-fact of
Pledgor, with full power of substitution, to do so);

            (ii) the Pledgeholder, on behalf of the Secured Parties, will be
entitled to receive and apply to the Indebtedness all cash Proceeds or other
distributions made in respect to the Pledged Shares or other Collateral;

            (iii) the Pledgeholder, on behalf of the Secured Parties, may
demand, sue for, collect or make any compromise or settlement of any claims that
the Secured Parties have in respect of payment of the Indebtedness or
foreclosure of the Collateral;

            (iv) the Pledgeholder, on behalf of the Secured Parties, may sell,
resell, assign and deliver, or otherwise dispose of any or all of the
Collateral, for cash or credit, or both, and upon such terms at such place or
places, at such time or times and to such entities or other persons as the
Pledgeholder thinks expedient, all in accordance with the Texas Uniform
Commercial Code;

                                       22
<PAGE>

            (v) the Pledgeholder, on behalf of the Secured Parties, may cause
all or any part of the Collateral to be transferred into the Secured Parties'
names or the names of Secured Parties' nominee or nominees, in satisfaction of
the Note and as payment of the Borrowed Amount, all in accordance with the Texas
Uniform Commercial Code;

            (vi) the Pledgeholder, on behalf of the Secured Parties, may
exercise any right, power or remedy or proceed against the Collateral in any
manner permitted by law or by this Agreement or the Note;

            (vii) the Pledgeholder, on behalf of the Secured Parties, may take
any other action permitted by this Agreement, the Note, at law or in equity, to
collect the Borrowed Amount; and

            (viii) Pledgor agrees that all Pledged Shares constitute collateral
of a type customarily sold on a recognized market. Accordingly, the Pledgeholder
and the Secured Parties shall all rights and remedies provided under the UCC
with respect to this type of collateral.

      The above rights, powers and remedies of the Pledgeholder, on behalf of
the Secured Parties, are cumulative and not exclusive. To the maximum extent
permitted by applicable law, Pledgor waives all claims, damages, and demands
against Secured Parties arising out of the possession, retention or sale of the
Collateral.

            (c) Pledgeholder's Right to Execute Documents. Pledgeholder shall
have the right to execute any document or form, in his name or in the name of
Pledgor, which may be necessary or desirable in connection with the retention or
sale of the Collateral.

      4. Pledgor's Waiver.

      Pledgor hereby waives (except as required by applicable statute and cannot
be waived) any right to require Pledgeholder (or the Secured Parties) to proceed
against any person or Collateral or to pursue any remedy in the power of the
Pledgeholder (or the Secured Parties).

      5. Pledgor's Representations, Warranties and Covenants.

            Pledgor represents, warrants and covenants to Secured Parties as
follows:

            (a) This Agreement creates a valid and enforceable security interest
in the Collateral.

            (b) Upon delivery to the Pledgeholder as contemplated hereby, the
Collateral will be free of any security interests, liens, pledges or
encumbrances created by Pledgor (except for the security interest created
hereby), or any claims of third parties of any nature whatsoever, charges,
escrows, options, rights of first refusal, or other agreements, restrictions,
arrangements, commitments or obligations, written or oral, created by Pledgor,
affecting the legal or beneficial ownership of the Collateral.

                                       23
<PAGE>

            (c) From and after the date hereof, Pledgor shall not make any
agreements restricting in any manner the transferability of the Collateral or
otherwise affecting the Collateral;

            (d) Pledgor shall, at Pledgor's expense, take any steps necessary to
preserve the Secured Parties' rights in the Collateral against any claims of
third parties;

            (e) Pledgor has arrangements for keeping informed of changes or
potential changes affecting the Collateral (including, without limitation,
rights to convert, rights to subscribe, payment of dividends, reorganization or
other exchanges, tender offers and voting rights), and the Pledgeholder and the
Secured Parties shall not have any responsibility or liability for informing
Pledgor of any such changes or potential changes or for taking any action or
omitting to take any action with respect thereto; and

            (f) So long as the Indebtedness remains unpaid, Pledgor shall not
cause, and Pledgor will employ reasonable commercial efforts to prevent, the
issuance by United Heritage Corporation of additional shares of Common Stock at
a price of less than $1.00 per share; provided, however, that United Heritage
Corporation shall issue 222,222 shares of its Common Stock to Richardson & Patel
LLP and a warrant to purchase an additional 222,222 shares of its Common Stock
to Richardson & Patel LLP, said warrant having an exercise price of $0.50 per
share and having a term of five years, all in accordance with the resolution
passed by the United Heritage Corporation Board of Directors on April 20, 2004;
and provided further that the Pledgeholder may from time-to-time, in accordance
with the requirements of subsection 8(g) of this Agreement, waive the rights of
the Secured Parties to the protection afforded by this section 5(f).

            (f) In view of the fact that federal and state securities laws may
impose certain restrictions on the method by which a sale of the Collateral may
be effected after a Default, and also upon the persons or entities who may
qualify or be eligible to purchase the Collateral, Pledgor hereby agrees that
upon the occurrence of a Default, the Pledgeholder may, from time to time, if
the Collateral is not publicly traded on a nationally recognized stock exchange
and/or is considered a "restricted" security, attempt to sell all or any part of
the Collateral by a private placement, upon commercially reasonable terms
restricting the bidders and prospective purchasers to a limited number who will
represent and agree that they are purchasing for investment for their own
accounts only and not for distribution, and who will otherwise meet state or
federal securities law requirements, including those pertaining to sales made
pursuant to exemptions from registration under the Securities Act of 1933 and/or
registration or qualification under other state or federal securities laws.

                                       24

      6. Matters Pertaining to Pledgeholder.

            (a) The Pledgeholder shall not be personally liable for any act he
may do or omit to do under this Agreement while acting in good faith and in the
exercise of his best judgment, and any act done or omitted by the Pledgeholder
pursuant to the advice of the Pledgeholder's attorney shall be conclusive
evidence of such good faith. Except as expressly provided herein, the
Pledgeholder is expressly authorized and directed to disregard any and all
notices or warnings given by any of the parties, or by any other person or
corporation, excepting only orders or process of court, and is hereby expressly
authorized to comply with and obey any and all orders, judgments or decrees of
any court. If the Pledgeholder obeys or complies with any such order, judgment
or decree of any court, he shall not be liable to any of the parties or any
other person, firm or corporation by reason of such compliance, notwithstanding
that any such order, judgment or decree be subsequently reversed, modified,
annulled, set aside or vacated, or found to have been entered without
jurisdiction.

            (b) The parties expressly agree the Pledgeholder has the absolute
right at the Pledgeholder's election, if the Pledgeholder considers it
appropriate, to file an action in interpleader in a court of proper jurisdiction
requiring the parties to answer and litigate their claims and rights among
themselves, and the Pledgeholder is authorized to deposit with the clerk of the
court all documents and funds held by him pursuant to this Agreement. In the
event such action is filed, the parties jointly and severally agree to pay all
costs, expenses and reasonable attorneys' fees that the Pledgeholder incurs in
such interpleader action. Upon filing of such action the Pledgeholder shall
thereupon be fully released and discharged from all obligations to further
perform any duties or obligations otherwise imposed by the terms of this
Agreement.

            (c) The Pledgeholder shall not be bound in any way by any other
agreement between the parties as to which the Pledgeholder is not a party,
whether or not the Pledgeholder has knowledge thereof, nor by any notice of a
claim or demand with respect to this Agreement or the Collateral. The
Pledgeholder shall have no duties or responsibilities except as expressly set
forth in this Agreement. The Pledgeholder may rely conclusively on any
certificate, statement, request, waiver, receipt, agreement or other instrument
that the Pledgeholder believes to be genuine and to have been signed and
presented by an appropriate person or persons.

            (d) The retention and distribution of the Collateral in accordance
with the terms and provisions of this Agreement shall fully and completely
release the Pledgeholder from any obligation or liability assumed by the
Pledgeholder hereunder as to the Collateral.

            (e) The Pledgeholder, while in possession of the Collateral prior to
or following the occurrence of an event of Default, as hereinabove provided, and
while acting in accordance with the terms of this Agreement or applicable law,
is not responsible for any fluctuations in value or delays in disposing of the
Collateral.

                                       25
<PAGE>

            (f) The Pledgeholder shall not be liable in any respect for
verifying the identity, authority or rights of the parties executing or
delivering or purporting to execute and/or deliver this Agreement or any
documents or papers deposited hereunder. The Pledgeholder shall not be liable
for the loss of any rights with respect to this Agreement or any documents
deposited with the Pledgeholder.

            (g) Notwithstanding anything herein to the contrary, the
Pledgeholder shall have no duty with respect to the Collateral other than the
duty to use reasonable care in the custody and preservation of the Collateral if
it is in the Pledgeholder's possession. The Pledgeholder shall be under no
obligation to take any steps necessary to preserve rights in the Collateral
against any other parties, to sell the Collateral if it threatens to decline in
value, or to exercise any rights represented thereby, including voting or
consensual rights, except as directed by Pledgor or the Secured Parties pursuant
to the terms of this Agreement.

                  (h) Pledgor and the Secured Parties agree to and each does
hereby indemnify, defend (with counsel acceptable to the Pledgeholder) and hold
the Pledgeholder harmless against any and all losses, damages, claims and
expenses, including reasonable attorneys' fees, that may be incurred by the
Pledgeholder by reason of his compliance with the terms of this Agreement. If,
as a result of any disagreement between the parties and/or adverse demands and
claims being made by any or all of them upon the Pledgeholder, the Pledgeholder
shall become involved in litigation, including any interpleader brought by the
Pledgeholder as provided in this Agreement, Pledgor and the Secured Parties each
agree that they shall be jointly and severally liable to the Pledgeholder on
demand for all costs, expenses and attorneys' fees that the Pledgeholder shall
incur and/or be compelled to pay by reason of such litigation.

      7. Replacement of Pledgeholder.

            In the event the Pledgeholder is or becomes unwilling or unable to
act in such capacity for any reason, the Secured Parties shall appoint a
successor. The Secured Parties (but not Pledgor) shall have the right, after
delivery of written notice signed by the Secured Parties to the Pledgeholder, to
terminate the Pledgeholder and to name the Pledgeholder's successor.

      8. Miscellaneous.

            (a) It is acknowledged by each party that such party either had
separate and independent advice of counsel or the opportunity to avail himself
or itself of same. This Agreement was prepared by each party in conjunction with
counseling from such party's respective attorney or the opportunity to obtain
such counseling. In light of these facts it is acknowledged that no party shall
be construed to be solely responsible for the drafting of this Agreement, and
therefore any ambiguity shall not be construed against any party as the alleged
draftsman of it. Each party shall pay all costs and expenses incurred or to be
incurred by such party in negotiating and preparing this Agreement and in
performing and complying with all representations, warranties, covenants,
agreements and conditions contained in this Agreement to be performed or
complied with by such party, including legal fees.

                                       26
<PAGE>

            (b) Each party agrees, without further consideration, to cooperate
and diligently perform any further acts, deeds and things and to execute and
deliver any documents that may be reasonably necessary to consummate, evidence,
confirm and/or carry out the intent and provisions of this Agreement, all
without undue delay or expense. Pledgor shall reimburse the Secured Parties for
any costs and expenses incurred by the Secured Parties in connection with any
breach or default of Pledgor under this Agreement, including collection efforts,
whether or not suit is commenced or judgment is entered. Furthermore, should any
party institute or should the parties otherwise become a party to any action or
proceeding to enforce or interpret this Agreement, the prevailing party in any
such action or proceeding shall be entitled to receive from the non-prevailing
party all costs and expenses of prosecuting or defending the action or
proceeding. This Agreement shall be governed in all respects by the laws of the
State of Texas as applied to agreements among Texas residents entered into and
to be performed entirely within Texas, without regard to the conflict of law
provisions thereof. Jurisdiction for the resolution of any dispute relating to
this Agreement, the Note or the Pledged Shares will be in a State District Court
in Johnson County, Texas.

            (c) The parties expressly acknowledge and agree that this Agreement:
(i) is the final, complete and exclusive statement of the parties' agreement
with respect to the subject matter hereof, (ii) supersedes any prior or
contemporaneous promises, assurances, guarantees, representations,
understandings, conduct, proposals, conditions, commitments, acts, course of
dealing, warranties, interpretations or terms of any kind, oral or written
(collectively "Prior Agreements"), and that any such Prior Agreements are of no
force or effect except as expressly set forth herein, and (iii) may not be
varied, supplemented or contradicted by evidence of such Prior Agreements or by
evidence of subsequent oral agreements. Any agreement hereafter made shall be
ineffective to modify, supplement or discharge the terms of this Agreement, in
whole or in part, unless such agreement is in writing and signed by the party
against whom enforcement of the modification, supplement or discharge is sought.
By execution hereof, the parties specifically disavow any desire or intention to
create a "third party" beneficiary contract, and specifically declare that no
person or entity, save and except for the parties and their permitted
successors, and assigns, shall have any rights hereunder nor any right of
enforcement hereof. No waiver of any breach of any agreement or provision herein
contained shall be deemed a waiver of any preceding or succeeding breach
thereof. If any term or provision of this Agreement or the application thereof
to any person or circumstance shall, to any extent, be determined to be invalid,
illegal or unenforceable, then the remaining part of this Agreement shall
nevertheless not be affected thereby and shall continue in full force and effect
to the fullest extent provided by law. This Agreement is to be read, construed
and applied together with the Note, which, taken together, set forth the
complete understanding and agreement of the parties with respect to the matters
referred to herein and therein.

                                       27
<PAGE>

            (d) Pledgor may not delegate its duties under this Agreement, in
whole or in part, without the prior written consent of the Secured Parties,
which consent may be withheld in the Secured Parties' sole and arbitrary
discretion. Notwithstanding the preceding sentence, no such delegation shall
release Pledgor from any liability or obligation under this Agreement without
the written consent of the Secured Parties, which consent may be withheld in the
Secured Parties' sole and arbitrary discretion. Subject to the foregoing, all of
the representations, warranties, covenants, conditions and provisions of this
Agreement shall be binding upon and shall inure to the benefit of each party and
such party's respective heirs, executors, administrators, legal representatives,
successors and/or assigns.

            (e) The headings used in this Agreement are for convenience and
reference purposes only, and shall not be used in construing or interpreting the
scope or intent of this Agreement or any provision hereof. References to this
Agreement shall include all amendments or renewals thereof. As used in this
Agreement, each gender shall be deemed to include each other gender, including
neutral genders or genders appropriate for entities, if applicable, and the
singular shall be deemed to include the plural, and vice versa, as the context
requires.

            (f) All notices, demands, requests, consents, approvals or other
communications ("Notices") given hereunder shall be as provided in the Note.

            (g) Except as expressly provided otherwise herein, neither this
Agreement nor any of the terms, provisions, obligations or rights contained
herein, may be amended, modified, supplemented, augmented, rescinded, discharged
or terminated (other than by performance), except by a written instrument or
instruments signed by all of the parties to this Agreement. No waiver of any
breach of any term, provision or agreement contained herein, or of the
performance of any act or obligation under this Agreement, or of any extension
of time for performance of any such act or obligation, or of any right granted
under this Agreement, shall be effective and binding unless such waiver shall be
in a written instrument or instruments signed by each party claimed to have
given or consented to such waiver and each party affected by such waiver. Except
to the extent that the party or parties claimed to have given or consented to a
waiver may have otherwise agreed in writing, no such waiver shall be deemed a
waiver or relinquishment of any other term, provision, agreement, act,
obligation or right granted under this Agreement, or any preceding or subsequent
breach thereof. No forbearance by a party to seek a remedy for any noncompliance
or breach by another party hereto shall be deemed to be a waiver by such
forbearing party of its rights and remedies with respect to such noncompliance
or breach, unless such waiver shall be in a written instrument or instruments
signed by the forbearing party.

      WHEREFORE, the parties hereto have executed this Agreement as of the date
first set forth above.

      __________________________________________________ (collectively, the
"Selling Shareholders"), Lothian Oil, Inc., a Delaware corporation
("Purchaser"), and Community Bank ("Escrow Agent") together agree as follows:

                                    RECITALS

      A. On this date the Selling Shareholders and the Purchaser entered into a
Securities Purchase Agreement (the "Securities Purchase Agreement") pursuant to
which the Selling Shareholders agreed to sell a total of 8,000,000 shares of the
Common Stock (the "Selling Shareholders' Common Stock") of United Heritage
Corporation (the "Company") to the Purchaser at a price of $1.331375 per share
for a total of $10,651,000.

      B. The Purchaser and the Selling Shareholders wish to appoint the Escrow
Agent as their agent to assist with the purchase and sale of the Selling
Shareholder's Common Stock, in accordance with the terms of this Escrow
Agreement.

      Therefore, the Selling Shareholders, the Purchaser and the Escrow Agent
agree as follows:

                                    AGREEMENT

      1. Appointment. The Selling Shareholders and the Purchaser hereby appoint
the Escrow Agent to serve as Escrow Agent for the purposes set forth herein and
the Escrow Agent hereby accepts the appointment.

      2. Deposits by the Purchaser for the benefit of the Selling Shareholders.
Upon the consummation of the transactions contemplated by the Securities
Purchase Agreement, the Purchaser shall deposit with the Escrow Agent good and

Agent will place the Escrow Deposit into an interest bearing account, with
interest accruing thereon for the benefit of the Purchaser.

      3. Close of Escrow. The Escrow Agent shall disburse the Escrow Deposit in
accordance with joint written instructions of Walter Mize, as agent for the
Selling Shareholders, and the Purchaser.

      4. Term. The term of this Agreement shall continue until the Escrow Agent
makes the transfers required by paragraph 3 above, provided, however, that this
Agreement shall terminate no later than January 31, 2006 unless the Escrow Agent
receives a written instruction executed by the Selling Shareholders and the
Purchaser extending the term of this Agreement and the Escrow Agent's duties
hereunder to another date.

      5. Escrow Agent's Costs and Fees. Costs incurred and fees charged by the
Escrow Agent shall be paid one-half by the Selling Shareholders and one-half by
the Purchaser. The Escrow Agent shall provide, in writing, a good-faith estimate
of its costs and fees to the Selling Shareholders and the Purchaser upon the
execution of this Agreement.

      6. Escrow Agent's Responsibility. The parties agree to provide to the
Escrow Agent all information necessary to facilitate the administration of this
Agreement and the Escrow Agent may rely upon any representation so made. Nothing
contained in this Agreement shall be construed to impose on the Escrow Agent the
duties of trustee for any party hereto or to impose on the Escrow Agent any
duties or obligations other than those for which there is an express provision
herein. For all purposes connected herewith the Escrow Agent shall be entitled
to assume that the parties hereto are fully authorized and empowered, without
affecting the rights of any third parties, to appoint the Escrow Agent as the
Escrow Agent in accordance with the terms and provisions hereof.

      7. Limitations on Liability. It is understood that the Escrow Agent shall
incur no liability, except for acts of gross negligence or willful misconduct.
None of the provisions hereof shall be construed so as to require the Escrow
Agent to expend or risk any of its own funds or otherwise incur any liability in
the performance of its duties under this Agreement. The Escrow Agent shall incur
no liability if it becomes illegal or impossible to carry out any of the
provisions herein. The Escrow Agent shall not be required to take or be bound by
notice of default of any person, or to take any action with respect to such
default involving any expense or liability, unless written notice of such
default is given to the Escrow Agent by the undersigned or any of them, and
unless the Escrow Agent is indemnified in a manner satisfactory to it against
such expense or liability. The Escrow Agent shall not be liable to any party
hereto in acting upon any written notice, request, waiver, consent, receipt or
other paper or document believed by the Escrow Agent to be signed by the proper
party or parties. The Escrow Agent will be entitled to treat as genuine and as
the document it purports to be any letter, paper, fax or other document
furnished or caused to be furnished to the Escrow Agent. The Escrow Agent shall
have no liability with respect to any good faith action taken or allowed by it
hereunder, except for acts of gross negligence or willful misconduct. The Escrow
Agent shall not be liable for any error of judgment or for any act done or step
taken or omitted by it in good faith or for any mistake of fact or law, except
for acts of gross negligence or willful misconduct, or for anything which it may
do or refrain from doing in connection herewith, and the Escrow Agent shall have
no duties to anyone except those signing this Agreement. The Escrow Agent may
consult with legal counsel in the event of any dispute or questions as to the
interpretation or construction of this Agreement or the Escrow Agent's duties
hereunder. In addition, the Escrow Agent shall incur no liability and shall be
fully protected in acting in accordance with the opinion and instructions of
counsel, except for acts of gross negligence or willful misconduct. In the event
of any disagreement between the undersigned or any person or persons named in
this Agreement, and any other person, resulting in adverse claims and demands
being made in connection with or for any money involved herein or effected
hereby, the Escrow Agent shall be entitled at its option to refuse to comply
with any such claims or demands, so long as such disagreement shall continue,
and in so doing the Escrow Agent shall not be or become liable for damages or
interest to the undersigned or any of them, or to any person named in this
Agreement, for its refusal to comply with such conflicting or adverse demands
and the Escrow Agent shall be entitled to continue so to refrain and refuse so
to act until (i) the rights of the adverse claimants have been finally
adjudicated in a court or by arbitration as set forth below assuming and having
jurisdiction of the parties and the property involved herein and affected
hereby; or (ii) all differences have been adjudicated by agreement and the
Escrow Agent has been notified thereof in writing by all of the persons
interested.

      8. Indemnification. In consideration of Escrow Agent agreeing to act as an
escrow agent pursuant to the terms and conditions of the Escrow Agreement, all
parties to this Agreement do hereby agree to indemnify Escrow Agent, its
officers, directors, agents, and employees, defend and hold the same harmless
for and against any and all claims, liability, actions, losses, costs, damages
or expenses, including attorneys' fees and expenses, which Escrow Agent may
sustain or incur, directly or indirectly, by reason of, or in consequence of,
Escrow Agent's acting or failing to act as escrow agent.

      9. Resignation of the Escrow Agent. The Escrow Agent reserves the right to
resign as the Escrow Agent at any time by giving 30 business days written notice
thereof to all parties at the last known address. Upon notice or resignation by
the Escrow Agent, the undersigned agree that the Escrow Agent may deliver any
property or documents that it holds to the replacement escrow agent. If no
notice is promptly received from the undersigned and the replacement Escrow
Agent, the Escrow Agent may petition any court of competent jurisdiction for
disposition of the property or documents and the Escrow Agent shall thereby be
released from any and all responsibility and liability to the parties hereto.

      10. Disputes. If at any time a dispute shall exist as to the duty of the
Escrow Agent under the terms hereof or if the property or documents deposited
hereunder are not withdrawn on or before the termination or expiration of this
Agreement, the Escrow Agent may deposit the property or documents with the Clerk
of the State District Court in Johnson County, Texas and may interplead the
parties hereto. Upon so depositing such property or documents and filing its
complaint in interpleader, the Escrow Agent shall be released from all liability
under the terms hereof as to the property or documents so deposited and
reimbursed for all expenses, including attorney fees. The parties hereto for
themselves consent and agree to the jurisdiction of said Court, and do hereby
appoint the Clerk of the said Court as their agent for the service of all
process in connection with the proceedings mentioned in this paragraph.

      11. Governing Law and Captions. This Agreement shall be governed and
interpreted by the laws of the State of Texas. The captions in this Agreement

      12. Counterparts. This Agreement may be executed in two or more

modified, superseded or canceled only by a written instrument executed by the
Issuer, the Selling Shareholders and the Purchaser and consented to in writing
by the Escrow Agent. Any of the terms and conditions hereof may be waived only
by a written instrument executed by the party waiving compliance therewith. The
failure of any party at any time or times to require performance of any
provision hereof shall in no manner affect such party's right at a later time to
enforce the same. No waiver by any party of any condition or of the breach of
any terms of this Agreement, whether by conduct or otherwise, in any one or more
instances shall be deemed to be or construed as a further or continuing waiver
of any such condition or breach or a waiver of any other condition or breach of
any other term of this Agreement.
