                                 PROXY STATEMENT
                                       For
                         ANNUAL MEETING OF SHAREHOLDERS
                          To Be Held August ____, 1999

      This Proxy Statement is furnished to shareholders of Middle Bay Oil
Company, Inc., an Alabama corporation ("Middle Bay"), in connection with the
solicitation, at Middle Bay's expense, on behalf of the Board of Directors of
Middle Bay of proxies to be used at an Annual Meeting of Shareholders to be held
at 10:00 a.m. Central Daylight Time on August ___, 1999 and all adjournments
thereof (the "Annual Meeting"). This Proxy Statement and the enclosed form of
proxy are being mailed to shareholders on or about July ___, 1999.

      The Annual Meeting will be held at the principal offices of Middle Bay at
1221 Lamar Street, Suite 1020, Houston, Texas 77010. Proxies in the form
enclosed will be voted at the Annual Meeting if properly executed, returned to
Middle Bay before the meeting and not revoked. Any shareholder giving such proxy
may revoke it at any time before it is voted by written revocation delivered to
Middle Bay's Secretary, by voting in person at the Annual Meeting or by giving a
later proxy.

      The cost of solicitation will be paid by Middle Bay. In addition to
solicitation of proxies by use of the mails, directors, officers or employees of
Middle Bay may, without additional compensation, solicit proxies personally, by
telephone or by other appropriate means. Middle Bay will request banks,
brokerage houses and other custodians, nominees or fiduciaries holding shares of
common stock in their names for others to promptly send proxy materials to, and
obtain proxies from, their principals, and Middle Bay will reimburse them for
their reasonable expenses in doing so.

                            OUTSTANDING CAPITAL STOCK

      All voting rights are vested exclusively in the holders of Middle Bay's
common stock. The record date for shareholders entitled to vote at the Annual
Meeting is the close of business on July ___, 1999. At the close of business on
that date, Middle Bay had issued, outstanding and entitled to vote at the
meeting 8,534,425 shares of common stock, $.02 par value, each of which is
entitled to one vote on all matters expected to be voted upon at the Annual
Meeting.

                                QUORUM AND VOTING

      The presence, in person or by proxy, of the holders of shares of common
stock entitled to vote at the Annual Meeting representing a majority of the
votes entitled to be cast is necessary to constitute a quorum at the Annual
Meeting. Each holder of shares of common stock is entitled to one vote, in
person or by proxy, for each share held in such shareholder's name on the record
date. Assuming the presence of a quorum, the affirmative votes equal to at least
a majority of the votes of holders of common stock entitled to vote at the
Annual Meeting, in person or by proxy, are required for the election of
directors and the approval of the selection of independent public accountants.
As to any other matters which may come before the meeting, a majority of the
votes of holders of common stock cast at the Annual Meeting generally is
required for approval. Abstentions will be included in vote totals and, as such,
will have the same effect on the matter voted upon as a negative vote. Where
nominee recordholders do not vote on directors or the other proposals because
they did not receive specific instructions on such proposal from the beneficial
owners of such shares ("broker nonvotes"), such broker nonvotes will not be
included in vote totals and, as such, will have no effect on the action taken at
the Annual Meeting.

      The shares represented by proxies solicited by the Board of Directors will
be voted in accordance with the recommendations of the Board of Directors unless
otherwise specified in the proxy, and where the person solicited specifies a
choice with respect to any matter to be acted upon, the shares will be voted in
accordance with the specification so made.

      The enclosed proxy is revocable at any time prior to its being voted by
filing an instrument of revocation or a duly executed proxy bearing a later
date. A proxy may also be revoked by attendance at the meeting and voting in
person. Attendance at the meeting will not by itself constitute a revocation.
Any such revocation or later dated proxy should be mailed or delivered to Middle
Bay Oil Company, Inc., 1221 Lamar Street, Suite 1020, Houston, Texas 77010,
Attention: Kelly L. Green, Assistant Secretary.

      Middle Bay will bear the cost of soliciting proxies from shareholders. In
addition to the use of the mails, proxies may be solicited by directors and
officers of Middle Bay by personal solicitation, telephone or telegram. Such
directors and officers will not be additionally compensated for such
solicitation but may be reimbursed for reasonable out-of-pocket expenses
incurred in connection therewith.

      Middle Bay has not and will not engage any investment banking or brokerage
firm or any professional proxy solicitation firm to solicit proxies. No fees,
commissions or other compensation will be paid to anyone for proxy votes
solicited by Middle Bay.

      Arrangements will be made with brokerage houses and other custodians,
nominees and fiduciaries for the forwarding of solicitation material to the
beneficial owners of the common stock. Middle Bay may reimburse such custodians,
nominees and fiduciaries for reasonable out-of-pocket expenses incurred in
connection therewith.

      The enclosed form of proxy allows shareholders to grant or withhold
discretionary authority to the persons named to vote on any other matters that
may properly come before the Annual Meeting. Middle Bay


                                      -2-
<PAGE>

is not aware of any other proposals planned to be made at the Annual Meeting and
has no current intention of making any additional proposals. The chairman of the
meeting shall determine the order of business at the Annual Meeting and the
voting and other procedures to be observed. The chairman is authorized to
declare whether any business is properly brought before the meeting, and
business not properly brought before the meeting may not be transacted.

                              CORPORATE GOVERNANCE

      The Board of Directors has the responsibility for establishing broad
corporate policies and for the overall performance of Middle Bay, taking into
consideration the interests of all shareholders. Members of the Board are kept
informed of Middle Bay's business by various reports sent or communicated to
them regularly, as well as by operating and financial reports made at Board and
Committee meetings by the President and other officers. During 1998, the full
Board met four times. The Board has two Committees, an Audit Committee and a
Compensation Committee. The Audit Committee met one time, and the Compensation
Committee met twice.

      The Audit Committee's duties include recommending to the Board the
selection of a firm of independent public accountants for approval by the
shareholders at their Annual Meeting. In addition, the Committee confers with
Middle Bay's independent public accountants to review the plan and scope of
their proposed audit, as well as their findings and recommendations upon the
completion of the audit. The Committee meets with the independent public
accountants and with appropriate Company financial personnel regarding Middle
Bay's internal controls and financial policies. The Audit Committee currently
consists of Gary R. Christopher, Frank E. Bolling, Jr. and Alvin V. Shoemaker.
No member of the Audit Committee is an officer or employee of Middle Bay.

      The Compensation Committee is responsible for establishing and reviewing
policies governing executive salaries, bonus and incentive compensation and the
terms and conditions of employment of executives of Middle Bay. In addition, the
Committee is responsible for the oversight of Middle Bay's 1995 Stock Option and
Stock Appreciation Rights Plan and similar or other plans which may be
maintained from time to time by Middle Bay and has authority to grant options
and awards under Middle Bay's 1995 Stock Option and Stock Appreciation Rights
Plan, and oversees Middle Bay's SEP/IRA retirement plan, the net profits
interest incentive compensation plan established by Middle Bay in 1995 and the
40l(k) plan established in 1997 (see "Corporate Governance - Executive
Compensation"). The Committee coordinates with the appropriate financial, legal
and administrative personnel of Middle Bay, as well as outside experts retained
in connection with the administration of these plans. The Compensation Committee
currently consists of John J. Bassett, President and Chief Executive Officer,
and Messrs. Edward P. Turner, Jr. and Frank E. Bolling, Jr., neither of whom is
an officer or employee of Middle Bay.

      During 1998, all incumbent directors attended all of the meetings of the
Board of Directors. Attendance at those meetings was 100%. Attendance at the
Committee meetings was also 100%.

Compensation of Directors

      Each director is paid an attendance fee of $500 for each meeting of the
Board and of each Committee of the Board, and Middle Bay reimburses directors'
documented travel and lodging expenses.

      Each nonemployee director is eligible for incentive awards under the 1995
Stock Option and Stock Appreciation Rights Plan. As previously reported in
Middle Bay's 1998 Proxy Statement, in January 1998, the Board of Directors
approved the Compensation Committee's recommendation to issue nonqualified stock
options pursuant to the Plan to nonemployee directors. These options were issued
as follows (see "Executive Compensation"):

                              Issued 1/98               Issued 2/99

Bay and changes in its Board of Directors and executive officers. The 3TEC
transactions are described under "Proposal to Approve the 3TEC Energy

approval.

</TABLE>

      Compensation Under Plans. Middle Bay established a SEP/IRA retirement plan
(the "Plan") in 1993 which allows for a maximum discretionary Company
contribution of 15% of total wages paid to employees for the year. For the years
ended December 1998 through 1996, Middle Bay made no contributions in 1998,
$51,5000 in 1997 and $5,000 in 1996 to the Plan, including $32,064 (1997) and
$3,068 (1996) for all executive officers as a group.

      Middle Bay established a 401(k) plan in October 1997, which allows for
voluntary contributions by the employees and the employer. No Company
contributions were made in 1998.

      In March 1995, the Board of Directors adopted an employee incentive
compensation plan whereby the proceeds equivalent to 1% net profits interest
(the "net profits interest") in all oil and gas properties, drilling prospects
and acquisitions and divestitures acquired or made after January 1, 1994 are
paid into a fund for incentive compensation awards to eligible employees.

      The net profits interest on property acquisitions and drilling prospects
are calculated on the monthly gross profit which is defined as revenues from oil
and gas sales, less direct operating expenses, attributable to Middle Bay's
working or royalty interest in an individual property. Direct operating expenses
include landowner's royalty, overriding royalty and all costs of production,
equipment, operating expenses and taxes. On drilling prospects, the net profits
interest will not include costs of drilling, testing and completing the well,
the costs of acreage and costs of geological or geophysical work. For
divestitures, the net profits interest will be calculated on the gross sales
price, less any direct costs of the sale of an individual property.

      To qualify for an award as an "eligible employee," as presently
established by the Compensation Committee, an employee must be employed by
Middle Bay on October 1 and December 31 of the calendar year and have been
recommended by the Compensation Committee to receive an award. For the year
ended December 31, 1996, Middle Bay paid $6,916 to employees through the
employee incentive plan, including $4,897 for all executive officers as a group.
No amount was paid into the employee incentive plan in 1997 or 1998.

      Middle Bay has no other retirement, pension/profit-sharing or other
deferred compensation.

      Option Grants in Last Fiscal Year. The 1995 Stock Option and Stock
Appreciation Rights Plan (the "Plan") is administered by the Compensation
Committee (the "Committee") of the Board of Directors. At least two members of
the Committee must be disinterested nonemployee directors. The Committee is
authorized to determine the employees, including officers, to whom options or
rights are granted. Each option or right granted shall be on such terms and
conditions consistent with the Plan as the Committee may determine, but the
duration of any option or right shall be not greater than ten years or less than
five years from the date of grant.

      Options or rights grants shall be made under the Plan only to persons who
are officers or salaried employees of Middle Bay or are nonemployee directors.
The aggregate number of shares of common stock of Middle Bay which could be
subject to options or rights under the Plan during 1998 was 1,500,000. During
the fiscal year ended December 31, 1998, options covering 232,000 shares were
issued under the Plan.

      The option price of shares covered by options granted under the Plan may
not be less than the fair market value at the time the option is granted. The
option price must be paid in full in cash or cash equivalent at the time of
purchase or prior to delivery of the shares in accordance with cash payment
arrangements acceptable to the Committee. If the Committee so determines, the
option price may also be paid in shares of Middle Bay's common stock already
owned by the optionee. The Committee has discretion to determine the time or
times when options become exercisable, within the limits set forth in the Plan.
All options and rights granted under the Plan will, however, become fully
exercisable if there is a change in control (as defined in the Plan) of Middle
Bay.

      The following table provides certain information with respect to all
options granted during the fiscal year ended December 31, 1998 to any executive
officer or director of Middle Bay; 232,000 options were granted under the Plan
and none were granted outside of the Plan:

Compliance with Section 16(a) of the Exchange Act

      Section 16(a) of the Securities Exchange Act of 1934 requires Middle Bay's
directors and executive officers and any persons who own more than 10% of Middle
Bay's common stock to file with the Securities and Exchange Commission reports
of ownership and changes in ownership of such securities. Based on
representations from such persons, Middle Bay believes that there was no failure
to file or delinquent filings


                                      -11-

under Section 16(a) of the Securities Exchange Act of 1934 by any officer,

Certain Relationships and Related Transactions

      Edward P. Turner, Jr., a director of Middle Bay, is managing partner of
the law firm of Turner, Onderdonk, Kimbrough & Howell, P.A., Middle Bay's
counsel for certain corporate and oil and gas matters. For the years ended
December 31, 1996 through 1998, Middle Bay paid legal fees to Mr. Turner's firm
of $1,560, $2,874 and $915, respectively, for legal services. Mr. Turner's firm
charges Middle Bay for its services on the same basis as it charges other
business clients for similar services rendered. Middle Bay intends to continue
to use Mr. Turner's firm as its primary local counsel in Alabama and will pay
reasonable fees for such future services.

      Bay City Energy Group, Inc., is presently indebted to Middle Bay in the
amount of $173,115 ($139,005 of principal and $34,110 of accrued interest). The
note payable was renegotiated on December 31, 1995 and is due in full on January
1, 2001, plus interest at an annual fixed rate of 5%. The note payable is
secured by 75,000 shares of Middle Bay's common stock. Edward P. Turner, Jr., a
director of Middle Bay, has indirect voting control but not a beneficial
interest in Bay City Energy Group, Inc.

      On December 31, 1996, NPC Energy Corp., then a company indirectly
controlled by C. J. Lett, III through Bison Energy Corporation ("Bison"), merged
with Middle Bay in exchange for 562,000 shares of common stock of Middle Bay and
$1,226,400 cash. Subsequently, in February, 1997, Middle Bay acquired Bison as a
wholly-owned subsidiary pursuant to an Agreement and Plan of Merger whereby Mr.
Lett received net cash consideration of $5.9 million plus 1,167,556 shares of
Middle Bay's common stock, and the 562,000 shares held by Bison (as a result of
the NPC merger) were canceled. Middle Bay rents office space for its division
office in Wichita, Kansas from Mr. Lett at the rate of $3,000 per month through
February, 2000.

      Middle Bay loaned Frank C. Turner, II, Vice President and Chief Financial
Officer, $14,400 in September, 1998 to pay income taxes associated with the
exercise of incentive stock options. The loan is represented by a note payable
on demand bearing interest at 8% per annum.

      Gary R. Christopher, a director of Middle Bay, is employed by
Kaiser-Francis Oil Company, which directly owns 3,333,334 common shares, or
39.1% of Middle Bay.

                  PROPOSAL TO INCREASE AUTHORIZED CAPITAL STOCK

      Middle Bay's amended Articles of Incorporation authorize twenty million
(20,000,000) common shares with a par value of $.02 per share and ten million
(10,000,000) preferred shares, the preferences and rights with respect to which
may be designated from time to time by the Board of Directors.

      Currently, there are 8,534,425 common shares issued and outstanding.
Shares of common stock may be issued from time to time as may be determined by
the Board of Directors. Each share of common stock has one vote for each share
of common stock standing in the name of the holder thereof on the books of
Middle Bay and entitled to vote. Cumulative voting is not allowed in the
election of directors or for any other purpose.

      Currently, there are 1,666,667 shares of preferred stock which have been
designated as Series A Preferred by the Board of Directors, none of which are
issued and outstanding. The 1,666,667 Series A Preferred shares which were
issued and outstanding in 1997 were converted into 3,333,334 shares of common
stock of Middle Bay on January 31, 1998.

      There are 266,667 shares of preferred stock which have been designated
Series B Preferred by the Board of Directors, of which 266,667 were issued in
connection with the Shore Merger and are presently outstanding. The Series B
Preferred shares are nonvoting but are convertible into as many as 1,333,333
shares of common stock, contingent upon the results of drilling and leasing
activity on mineral acreage in South Louisiana acquired in the Shore Merger.

      There are 2,300,000 shares of preferred stock which have been designated
Series C Preferred by the Board of Directors, 2,173,645 of which are issued and
outstanding. The Series C shares pay cumulative cash dividends at the rate of
10% per annum and have a $5.00 per share liquidation preference over common
stock. The Series C shares are nonvoting, but are convertible, share for share,
into shares of common stock.

      Additional shares of authorized preferred stock may be issued from time to
time by the Board of Directors in one or more series, with each series having
such designation rights (including voting rights or the absence thereof) and
preferences as may be determined by the directors.

      The Board of Directors believes that it is in the best interests of Middle
Bay to amend Middle Bay's Articles of Incorporation to increase authorized
common stock to 40,000,000 shares of common stock, $.02 par value, and to
increase the authorized preferred stock to 20,000,000 shares to have additional
shares available for issuance should Middle Bay determine to raise equity
capital and for purposes of facilitating future acquisitions. A copy of the
proposed Articles of Amendment to Middle Bay's Articles of Incorporation which
has been approved by the Board of Directors is included herewith as Exhibit "A".

      The Board of Directors recommends that the shareholders vote FOR the
proposal to increase the authorized capital stock of Middle Bay.

              PROPOSAL TO RATIFY ACQUISITION OF OIL AND GAS ASSETS
                    FOR SERIES C CONVERTIBLE PREFERRED STOCK

      On December 30, 1998, Middle Bay completed the acquisition of all of the
oil and gas properties of Enex Consolidated Partners, L.P., a publicly-held oil
and gas limited partnership (the "Enex Partnership"). The transaction had an
economic effective date of October 1, 1998.

      The transaction, which was valued at $11.9 million, involved the issuance
of 2,177,481 shares of Middle Bay's Series C Convertible Preferred stock
("Series C") in exchange for the outstanding limited partnership interests of
the Enex Partnership, the transfer of the Enex Partnership's assets and
liabilities to Middle Bay, and the dissolution of the Enex Partnership. Enex
Resources Corporation ("Enex Resources"), an 80%-owned subsidiary of Middle Bay,
was general partner of the Partnership and owned 56.24% of the total outstanding
limited partnership units, for which it received 1,293,522 Series C shares
(59.4% of the Series C shares issued in the transaction).

      The Series C shares pay cumulative cash dividends at the rate of 10% per
annum. Each share has a $5.00 per share liquidation preference over common stock
and is convertible into one share of Middle Bay common stock.

      Total proved reserves of the properties acquired were approximately 8,958
MMCF of natural gas and 797 thousand barrels of oil with a PV 10% value of $14.1
million as of October 1, 1998, based upon an independent engineering reserve
report. On an equivalent barrel basis, the reserves are 65% gas with 82%
classified as proved developed producing. The properties are located primarily
in Texas. In addition, the Enex Partnership had approximately $1.0 million in
working capital which was acquired in the transaction. The Enex Partnership's
oil and gas properties increased the net proved reserves of Middle Bay by
approximately 10%.

      The Enex Partnership transaction and the designation and issuance of the
Series C shares were unanimously approved by Middle Bay's Board of Directors
after a review of the transaction and recommendation by the Audit Committee of
the Board. Shareholder approval of the transaction by Middle Bay shareholders
was not required under the Alabama Business Corporation Act and was not sought
(except to the extent that the Directors voting in favor of the transaction
represented more than a majority of the issued and outstanding shares of common
stock of Middle Bay). An independent investment banking firm issued an opinion
that the transaction was fair from a financial point of view to the public
holders of Enex Partnership interests.

      Application has been made to list the Series C on the Nasdaq Small Cap
Stock Market (the "Application"). It is in connection with this Application that
ratification of the transaction by shareholders of Middle Bay is being sought.
The Nasdaq Stock Market ("Nasdaq") staff has deferred approval of the
Application pending a review of Middle Bay's compliance with Nasdaq's corporate
governance rules regarding issuance of additional shares of equity securities.
The Nasdaq staff has informed Middle Bay that since the Series C shares are
convertible, share for share, into shares of common stock of Middle Bay, the


                                      -16-
<PAGE>

transaction may have involved the issuance of potentially more than 20% of the
then outstanding shares of Middle Bay common stock. The Nasdaq corporate
governance rules under such circumstances would have required approval by a
majority of the issued and outstanding shares of common stock of Middle Bay
prior to the issuance of the Series C shares.

      Middle Bay believes the Series C shares were issued in compliance with the
Nasdaq corporate governance rules and prior shareholder approval of the
transaction was not required because the Series C shares presently outstanding,
if converted to common stock, would potentially represent less than 20% of the
issued and outstanding common stock of Middle Bay. This position is supported by
the fact that Enex Resources, Middle Bay's 80%-owned subsidiary, received 59.4%
of the Series C shares. For accounting, reporting and all practical purposes,
only 20% (the percentage of minority shareholders of Enex Resources) of the
Series C shares held by Enex Resources are considered outstanding and held by
third parties. The consolidated financial statements of Middle Bay as of
December 31, 1998 show 1,142,663 Series C shares outstanding (which includes the
250,704 Series C shares attributable to the minority shareholder interest in
Enex Resources) and 8,530,589 shares of common stock outstanding. If all
1,142,663 Series C shares were converted into 1,142,663 shares of Middle Bay
common stock, they would represent only 13.4% of the 8,530,589 shares of common
stock issued and outstanding as of the transaction date. Accordingly, Middle Bay
believes that the issuance of the Series C shares did not require prior
shareholder approval.

      No final determination has been made by Nasdaq regarding the Application,
and Middle Bay has determined to include the ratification of the transaction in
this Proxy Statement in an effort to accommodate the Nasdaq staff in its
approval process. Since the Directors of Middle Bay represent major shareholders
of Middle Bay with voting power in excess of a majority of the issued and
outstanding common stock, the ratification being sought is assured.

      The Board of Directors recommends that the shareholders vote FOR
ratification of the issuance of Series C Convertible Preferred stock of Middle
Bay.

                 PROPOSAL TO APPROVE THE 3TEC ENERGY CORPORATION
                          SECURITIES PURCHASE AGREEMENT

      On July 1, 1999, 3TEC Energy Corporation ("3TEC"), a privately-held
Delaware corporation based in Dallas, Texas, entered into a Securities Purchase
Agreement (the "Agreement") with Middle Bay involving initially a $21,400,000
investment by 3TEC in equity and debt. The Agreement, if consummated, would
result in 3TEC becoming Middle Bay's largest shareholder. Other provisions of
the Agreement would cause changes in Middle Bay's Board of Directors and the
installation of a new President and Chief Executive Officer, resulting in a
change of control and management structure of Middle Bay. The cash proceeds to
Middle Bay from the transaction would be added to its working capital and be
available for acquisition, development and exploration of oil and gas
properties.

      The following is a summary of the principal terms of the Agreement. A
complete copy of the Agreement is included as Exhibit "B" to this Proxy
Statement. The Agreement includes as exhibits the Registration Rights Agreement,
Shareholders' Agreement, Agreement of Shareholders and the executive employment
agreements referred to below.

            o     Purchase and Sale of Securities - 3TEC will purchase 4,755,556
                  shares of new issue Middle Bay common stock plus five-year
                  warrants to purchase (at $1.00 per share) 3,600,000 shares of
                  common stock, for a total purchase price of $10,700,000. The
                  purchase price is payable $20,525,000 in cash and $875,000 in
                  agreed value of certain oil and gas properties to be assigned
                  to Middle Bay.

                  --    3TEC will lend to Middle Bay $10,700,000, for which
                        Middle Bay will issue a five-year senior subordinated
                        convertible promissory note (the "Note"). The Note is
                        convertible at any time into Middle Bay common stock at
                        $3.00 per share (a total of 3,566,667 common shares).
                        Interest at 9% per annum is payable quarterly. Middle
                        Bay may defer 50% of the first eight interest payments
                        and add them to the principal due at maturity. The Note
                        is subordinate to Middle Bay's bank credit facility, but
                        senior to other debt. 3TEC (as noteholder) must approve
                        any change in the credit facility, corporate structure
                        and major transactions of Middle Bay until the Note is
                        paid.

                  --    Sixty percent (60%) of the warrants may be exercised by
                        3TEC at any time. The remaining 40% may be exercised
                        incrementally over the five-year term of the warrants.
                        The warrants may be exercised for cash or reduction of
                        the Note principal.

            o     Registration Rights - 3TEC has a two-time demand right to have
                  its Middle Bay common stock registered with the Securities and
                  Exchange Commission (at Middle Bay's expense) and has
                  "piggyback rights" (with certain other principal shareholders
                  of Middle Bay having subordinate piggyback rights) to have its
                  common stock registered and publicly sold along with any
                  public offering of securities by Middle Bay.

<PAGE>

            o     Agreement to Vote for the 3TEC Agreement - Certain major
                  shareholders (collectively, the "Major Shareholders") of
                  Middle Bay, Kaiser-Francis Oil Company, C. J. Lett, III,
                  Weskids, L.P. and Alvin V. Shoemaker (see "Corporate
                  Governance - Security Ownership of Certain Beneficial
                  Owners"), have agreed to vote in favor of the 3TEC Agreement,
                  thereby assuring approval of the Agreement at the
                  Shareholders' meeting.

            o     Potential Participation by Major Shareholders - One or more of
                  the Major Shareholders, prior to the closing of the Agreement,
                  may enter into agreements substantially identical to the 3TEC
                  Agreement and may invest up to an aggregate of $20,000,000 in
                  Middle Bay securities on similar terms as 3TEC. No Major
                  Shareholder has agreed to such participation as of the date of
                  this Proxy Statement.

            o     Board of Directors of Middle Bay - The Board of Directors
                  would be reduced to five members. 3TEC has the right to
                  designate three Directors, and the Major Shareholders have the
                  right to designate two. A Shareholders' Agreement would be
                  signed by 3TEC and the Major Shareholders assuring election of
                  the designated Directors.

            o     Floyd C. Wilson Employment Agreement. Floyd C. Wilson,
                  President and a shareholder of 3TEC, would become Chairman,
                  President and Chief Executive Officer of Middle Bay. Middle
                  Bay's current Chairman and President, John J. Bassett, would
                  become Middle Bay's Executive Vice President and would be one
                  of the two Directors designated by the Major Shareholders. Mr.
                  Wilson would have an employment agreement commencing at

                        in the event of any liquidation, dissolution or winding
                        up of the affairs of the Corporation;

                  (5)   the rights, if any, of the holders of preferred shares

      provisions relating to the foregoing matters between the various series of
      Preferred Shares, but in all other respects the shares of each series of
      Preferred Shares, shall be of equal rank with each other, regardless of
      series. All of the Preferred Shares of any one series shall be identical
      with each other in all respects.

            (d) Dividend Rights. The holders of the Preferred Shares of any
      series shall be entitled to receive, as and when declared by the Board of
      Directors, out of funds


                                      -2-
<PAGE>

      legally available for that purpose under the laws of the State of Alabama,
      preferential dividends which may be either cumulative or noncumulative at
      the rate per annum fixed by the Board of Directors for such series. Such
      dividends shall be payable at the time determined by the Board of
      Directors. If Preferred Shares of more than one series are outstanding,
      and the stated dividend is not paid in full, all series of Preferred
      Shares shall share ratably in the payment of dividends including
      accumulations, if any, in accordance with the sum which would be payable
      on such shares if all dividends were declared and paid in full.
      Accumulations of dividends shall not bear interest. So long as any
      Preferred Shares shall remain outstanding, no dividends shall be declared
      or paid to any distributions made on the Common Shares or on any other
      class of shares junior to the Preferred Shares, and no share of common or
      of any other class junior to the Preferred Shares shall be purchased or
      retired, and no monies shall be made available for a sinking fund for such
      purpose unless dividends for all past dividend periods shall have been
      paid on all outstanding Preferred Shares of all series. Subject to the
      above provisions, and not otherwise, dividends may be paid from time to
      time on the Common Shares or other junior issues out of funds legally
      available for the purpose as and when declared by the Board of Directors.

            (e) Redemption.

                  (1)   The Corporation, on the sole authority of the Board of
                        Directors, may at its option redeem all or any part of
                        any series of the Preferred Shares on the terms,
                        including redemption price, and to the extent, if any,
                        therefor affixed by the Board of Directors. Such
                        redemption may be effected only after dividends which
                        have been declared or accrued on any series of Preferred
                        Shares have been paid. If less than all of the Preferred
                        Shares of any series is to be redeemed, the redemption
                        shall be in such amount and by such method, whether by
                        lot or pro rata, or by such other method as may then be
                        required by law or by the rules and regulations of any
                        stock exchange upon which the Preferred Shares may at
                        that time be listed, as may from time to time be
                        determined by the Board of Directors. Written notice of
                        redemption stating the date and place of redemption
                        shall be mailed by the Corporation, not less than thirty
                        (30) days nor more than forty-five (45) days prior to
                        the redemption date, to the record holders of the shares
                        to be redeemed, directed to their last noted addresses
                        as shown by the corporate records.

                  (2)   If notice of redemption is given as provided above, and
                        if on the redemption date the Corporation has set apart
                        in trust for the


                                      -3-
<PAGE>

                        purpose, sufficient funds for such redemption, then from
                        and after the redemption date, notwithstanding that any
                        certificate for such shares has not been surrendered for
                        cancellation, the Preferred Shares called for redemption
                        shall no longer be deemed outstanding and all rights
                        with respect to such shares shall forthwith cease and
                        terminate, except on the right of the holders thereof to
                        receive the redemption price, without interest, upon
                        surrender of certificates of the shares called for
                        redemption.

                  (3)   Any funds so set apart or deposited which, at the end of
                        one (1) year after the redemption date, remain unclaimed
                        by the holder(s) of Preferred Shares called for
                        redemption, shall be released and returned to the
                        Corporation upon demand, and shall thereafter be
                        available for general corporate purposes, and the
                        depository, if any, shall thereupon be relieved of all
                        responsibility therefor to such holders. Any interest
                        accrued on funds so deposited shall be paid to the
                        Corporation from time to time.

                  (4)   Preferred Shares which are redeemed as provided in this
                        section, or are reacquired for retirement pursuant to
                        any sinking fund which may be established therefor, may
                        be held as Treasury Shares or may be canceled and
                        retired in the manner provided by law, and appropriate
                        proceedings to effect the corresponding reduction in the
                        stated capital of the Corporation shall be taken.

            (f) Rights on Liquidation. In the event of the liquidation,
      dissolution, or winding up of the Corporation, whether voluntary or
      involuntary, resulting in any distribution of its assets to its
      shareholders, the holders of the Preferred Shares then outstanding shall
      be entitled to receive the amount per share theretofore affixed by the
      Board of Directors of the various series, plus any accrued interest, and
      no more, before any payment or distribution of the assets of the
      Corporation is made to or set apart for the holders of Common Shares or
      any other class junior to the Preferred Shares. If the assets of the
      Corporation distributable to the holders of all the Preferred Shares are
      insufficient for the payment to them of the full preferential amount
      described above, such assets shall be distributed ratably among the
      holders of all Preferred Shares of all series in accordance with the
      amounts which would be payable on such distribution of all sums payable
      were discharge in full. After payment for the preferential amounts
      required to be paid to the holders of all Preferred Shares then
      outstanding, the holders of Preferred Shares and/or any other class junior
      to the Preferred Shares shall be entitled, to the exclusion of the holders
      of any of the Preferred Shares, to share in all remaining assets of the
      Corporation


                                      -4-

      in accordance with their respective interests.

            For the purposes of this Section and any certificate filed pursuant
      to law and setting forth the designation, description, and terms of any
      series of Preferred Shares, a consolidation or merger of the Corporation
      with any other corporation or corporations shall not be deemed a
      liquidation, or winding up of the Corporation."

      All other provisions of the Amended Articles of Incorporation shall remain

      SECTION 4.1. Exercise of Warrants.

      (a) One-half of the Warrants may be exercised in whole or in part at any
time until the Warrant Expiration Date at which time the Warrants shall expire
and shall thereafter no longer be exercisable.

      (b) The other half of the Warrants (the "Restricted Warrants") may be
exercised, in whole or in part, until the Warrant Expiration Date, as follows:

      (i)   up to 20% of the Restricted Warrants may be exercised during the one
            (1) year period commencing on the Closing Date;

      (ii)  up to 40% of the Restricted Warrants (inclusive of any prior
            exercise under this subsection (b)) may be exercised during the one
            (1) year period commencing twelve (12) months after the Closing
            Date;

      (iii) up to 60% of the Restricted Warrants (inclusive of any prior
            exercise under this subsection (b)) may be exercised during the one
            (1) year period commencing twenty-four (24) months after the Closing
            Date;

      (iv)  up to 80% of the Restricted Warrants (inclusive of any prior
            exercise under this subsection (b)) may be exercised during the one
            (1) year period commencing thirty-six (36) months after the Closing
            Date; and


                                       12
<PAGE>

      (v)   up to 100% of the Restricted Warrants (inclusive of any prior
            exercise under this subsection (b)) may be exercised during the one
            (1) year period commencing forty-eight (48) months after the Closing
            Date;

      Notwithstanding the foregoing, in any event, the Restricted Warrants may
be exercised at the earlier of:

      (i)   the conversion of all or part of the Note into shares of Common
            Stock, subject to the restrictions set forth below in Section
            4.1(c);

      (ii)  a Change of Control; or

      (iii) the payment in full of the Note.

      (c) If the entire amount of principal and interest due and payable under
the Note is converted to Common Stock, all of the Restricted Warrants shall be
immediately exercisable in whole or in part at any time until the Warrant
Expiration Date. If less than the entire amount of principal and interest due
and payable under the Note is converted, a pro-rata portion of the Restricted
Warrants based upon the amount of the Note which is converted compared to the
total amount of the Note prior to conversion, shall be immediately exercisable
in whole or in part at any time until the Warrant Expiration Date. For example,
if fifty percent (50%) of the Note is converted, one half of the Restricted
Warrants would be exercisable.

      (d) The Warrants shall be exercised by presentation of the Warrant
Certificate evidencing the Warrants to be exercised, with the form of election
to purchase on the reverse thereof duly completed and signed, to the Company at
the offices of the Company as set forth on the signature page of this Agreement,

Warrant Shares in respect of which such Warrants are being exercised in lawful
money of the United States of America; provided, that, to the extent the Warrant
Holder exercising such Warrants is also the holder of a Note, such Warrant
Holder or Noteholder may elect, by written notice to the Company delivered with
such presentation, to elect to pay the applicable Warrant Exercise Price by
offsetting the next scheduled payment of such Note by an amount equal to the
aggregate Warrant Exercise Price payable in connection with such exercise of
Warrants. Upon such presentation, the Company shall issue and cause to be
delivered to or upon the written order of the registered Holder of such Warrants
and in such name or names as such registered Holder may designate, a certificate
or certificates for the aggregate number of Warrant Shares issued upon such
exercise of such Warrants. Any Person so designated to be named therein shall be
deemed to have become holder of record of such Warrant Shares as of the date of
exercise of such Warrants; provided, that, no Warrant Holder will be permitted
to designate that such Warrant Shares be issued to any Person other than such
Warrant Holder unless each condition to transfer contained in Article V hereof
which would be applicable to a transfer of Warrants or Warrant Shares has been
satisfied.

            (b) If less than all of the Warrants evidenced by a Warrant
Certificate are exercised at any time, a new Warrant Certificate or Certificates
shall be issued for the remaining number of Warrants evidenced by such Warrant
Certificate. All Warrant Certificates surrendered upon exercise of Warrants
shall be canceled.


                                       13
<PAGE>

            (c) The Company shall not be required to issue fractional shares of
Common Stock upon exercise of any Warrants issued by it, but shall pay for any
such fraction of a share an amount in cash equal to the value of such fractional
share determined by the Company's board of directors in good faith.

            (d) The Company will pay all Taxes attributable to the initial
issuance of Warrant Shares upon the exercise of the Warrants issued by it;
provided, that, each Warrant Holder shall use its reasonable efforts to avoid
any such Tax on the issuance of Warrant Shares; and provided, further that, the
Company shall not be required to pay any income Tax or any other Tax which may
be payable in respect of any transfer involved in the issue of any Warrant
Certificate or any certificate for Warrant Shares in a name other than that of
the registered holder of a Warrant Certificate surrendered upon the exercise of
such a Warrant, and the Company shall not be required to issue or deliver such
certificates unless or until the Person or Persons requesting the issuance
thereof shall have paid to the Company the amount of such Tax or shall have
established to the satisfaction of the Company that such Tax has been paid.

      SECTION 4.2. Adjustment of Number of Warrant Shares Purchasable. The
number of Warrant Shares purchasable upon the exercise of each Warrant is
subject to adjustment from time to time upon the occurrence of any of the events
enumerated in this Section 4.2.

      (a) In the event that the Company shall at any time after the date of this
Agreement declare a dividend on the Common Stock in shares of its capital stock
(whether shares of such Common Stock or of capital stock of any other class of
the Company), split or subdivide the outstanding Common Stock, or combine the
outstanding Common Stock into a smaller number of shares, the number of Warrant
Shares purchasable upon an exercise of each Warrant after the time of the record
date for such dividend or of the effective date of such split, subdivision or
combination shall be adjusted to equal the number of shares of Common Stock
which a Holder having the same number of shares of Common Stock as the number of
Warrant Shares into which each Warrant is exercisable immediately prior to such
record date or effective date, as the case may be, would own or be entitled to
receive after such record date or effective date.

      (b) In the event that the Company shall at any time after the date of this
Agreement issue any shares of Common Stock without consideration or at a price
per share less than $1.00, or issue options, rights or warrants to subscribe for
or purchase such Common Stock (or securities convertible into such Common Stock)
without consideration or at a price per share (or having a conversion price per
share, if a security convertible into such Common Stock) less than $1.00, the
number of Warrant Shares purchasable upon an exercise of each Warrant after the
date of such issuance shall be adjusted to equal the product obtained by
multiplying the number of Warrant Shares into which each Warrant is exercisable
immediately prior to the date of such issuance by a fraction, the numerator
shall be the number of shares of Common Stock outstanding on a Fully Diluted
Basis immediately after such issuance, and the denominator of which shall be the
number of shares of Common Stock outstanding on a Fully Diluted Basis
immediately prior to such issuance plus the number of shares of such Common
Stock which the aggregate offering price of the total number of shares of such
Common Stock so to be issued or to be offered for subscription or purchase (or
the aggregate initial conversion price of the convertible securities so to be
offered) would purchase at $1.00 per share. In case such subscription price may
be paid in a consideration part or all of which shall be in a form other than
cash, the value of such consideration shall be as determined by an investment
banker reasonably acceptable to the Warrant Holder (the cost of the engagement
of said investment banking firm to be borne by the Company). Shares of such
Common Stock owned by or held for the account of the Company or any Subsidiary
thereof shall not be deemed outstanding for the purpose of any such computation.
Such adjustment shall be made successively whenever the date of such issuance is
fixed (which date of issuance shall be the record date for


                                       14
<PAGE>

such issuance if a record date therefor is fixed); and, in the event that such
shares or options, rights or warrants are not so issued, the number of Warrant
Shares into which each Warrant is exercisable shall again be adjusted to be such
number of Warrant Shares into which each Warrant is exercisable if the date of
such issuance had not been fixed.

      (c) In case the Company shall make a distribution to all holders of Common
Stock (including any such distribution made in connection with a consolidation
or merger in which the Company is the surviving corporation) of shares of it
stock, evidences of its indebtedness, assets, or rights, options or warrants
(other than those referred to in subsection (b) of this Section 4.2) to
subscribe for or purchase such shares, evidences of indebtedness, or assets, the
number of Warrant Shares into which each Warrant is exercisable after such date
of distribution shall be adjusted to equal the product obtained by multiplying
the number of Warrant Shares purchasable upon an exercise of each Warrant
immediately prior to such date by a fraction, the numerator of which shall be
the Per Share Stock Price for the trading day immediately preceding the day of
distribution ("Pre-Distribution Price"), and the denominator of which shall be
the Pre-Distribution Price less the fair market value of the distribution (as
determined in good faith by the Board of Directors of the Company) applicable to
one share of Common Stock. Such adjustment shall be made successively whenever a
date for such distribution is fixed (which date of distribution shall be the
record date for such issuance if a record date therefor is fixed); and, if such
distribution is not so made, the number of Warrant Shares into which each
Warrant is exercisable shall again be adjusted to be such number of Warrant
Shares which would then be in effect if the date of such distribution had not
been fixed.

      (d) No adjustment in the number of Warrant Shares purchasable upon an
exercise of each Warrant shall be required unless such adjustment would require
an increase or decrease of at least one-tenth of one percent (.1%) in such
number of Warrant Shares; provided that any adjustments which by reason of this
Section 4.2(d) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this Section
4.2 shall be made to the nearest hundredth of one percent.

      (e) The Warrant Exercise Price in effect immediately prior to any
adjustment of the number of Warrant Shares into which each Warrant is
exercisable shall be simultaneously adjusted (but not below the par value of the
Common Stock) by multiplying the Warrant Exercise Price immediately prior to
such adjustment by a fraction, the numerator of which shall be the number of
Warrant Shares into which each Warrant is exercisable immediately prior to such
adjustment, and the denominator of which shall be the number of Warrant Shares
into which each Warrant is exercisable immediately after such adjustment.

      (f) In the event of any capital reorganization of the Company, or of any
reclassification of any Common Stock for which any Warrant is exercisable (other
than a subdivision or combination of outstanding shares of such Common Stock),
or in case of the consolidation of the Company with or the merger of the Company
with or into any other corporation or of the sale of the properties and assets
of the Company as, or substantially as, an entirety to any other Person, each
Warrant shall after such capital reorganization, reclassification of such Common
Stock, consolidation, merger or sale be exercisable, upon the terms and
conditions specified in this Agreement, for the number of shares of stock or
other securities or assets to which a holder of the number of Warrant Shares
purchasable (at the time of such capital reorganization, reclassification of
such Common Stock, consolidation, merger or sale) upon exercise of such Warrant
would have been entitled upon such capital reorganization, reclassification of
such Common Stock, consolidation, merger or sale; and in any such case, if
necessary, the provisions set forth in this Section 4 with respect to the rights

reasonably be, to any shares of stock or other securities or assets thereafter

consummation thereof, the successor corporation (if other than the Company)
resulting from such consolidation or merger or the corporation purchasing such
assets or the appropriate corporation or entity shall assume, by written

Shares upon exercise of each Warrant or to distribute certificates that evidence

value of any such fractional Warrant Shares.

      SECTION 4.3 Notices to Warrant Holders. Upon any adjustment of the number
of Warrant Shares issuable upon an exercise of the Warrants or any adjustment of
the Warrant Exercise Price pursuant to Section 4.3, the Company shall promptly,
but in any event within thirty (30) days thereafter, cause to be given to each
Warrant Holder, at its address appearing on the Warrant Register, by first class
mail, postage prepaid, a certificate signed by the Company's Financial Officer

Warrant as so adjusted and the Warrant Exercise Price as so adjusted, and

      (c) that the Company shall authorize the distribution to all holders of
its Common Stock of shares of its stock, evidences of its indebtedness, assets,
or rights, options, or warrants to subscribe for or purchase such shares,
evidences of indebtedness or assets; or

      (d) of any consolidation or merger to which the Company is a party and for
which approval of any shareholders of the Company is required, or of the
conveyance or transfer of the properties and assets of the Company substantially
as an entirety, or of any capital reorganization or reclassification or change
of the Common Stock (other than a change in par value, or from par value to no
par value, or from no par value to par value, or as a result of a subdivision or
combination); or

      (d) of the voluntary dissolution, liquidation or winding up of the
Company; or

      (e) that the Company proposes to take any other action which would require

days prior to the applicable date hereinafter specified, by first class mail,
postage prepaid, a written notice stating the date as of which the holders of
record of Common Stock to be entitled to receive any such rights, warrants or
distribution are to be determined, or the date on which any such consolidation,

to become effective, and the date as of which it is expected that the holders of
record of Common Stock shall be entitled to exchange their shares for securities
or other property, if any, deliverable upon such reclassification,
consolidation, merger, conveyance, transfer, dissolution, liquidation or winding
up.

      SECTION 4.4. Reservation and Issuance of Warrant Shares. The Company will
at all times have authorized, and reserve and keep available, free from
preemptive rights, for the purpose of enabling it to satisfy any obligation to
issue Warrant Shares upon the exercise of the Warrants, the number of shares of
Common Stock deliverable upon exercise of all outstanding Warrants. The Company
covenants that all Warrant Shares issued by it will, upon issuance in accordance
with the terms of this Agreement, be fully paid and nonassessable and free from
all Taxes with respect to the issuance thereof and free from all Liens other
than Liens arising by, through or under the Warrant Holder to whom such Warrant
Shares were issued.

                             TRANSFER OF SECURITIES

      Section 5.1. Restrictions on Transfer. 3TEC understands and agrees that
the Securities have not been registered under the Securities Act or any state
securities Laws, and that accordingly, they will not be fully transferable
except as permitted under various exemptions contained in the Securities Act and
applicable state securities Laws, or upon satisfaction of the registration and
prospectus delivery requirements of the Securities Act and applicable state
securities Laws. 3TEC acknowledges that it must bear the economic risk of its
investment in the Securities for an indefinite period of time (subject, however,
to the payment terms of the Note, and the Company's obligations pursuant to the
Registration Rights Agreement) since they have not been registered under the
Securities Act and applicable state securities Laws and therefore cannot be sold
unless they are subsequently registered or an exemption from registration is
available. Absent an effective registration statement under the Securities Act
and applicable state securities Laws covering the disposition


                                       17
<PAGE>

of the Securities, 3TEC will not sell, transfer, assign, pledge, hypothecate or
otherwise dispose of any or all of the Securities absent a valid exemption from
the registration and prospectus delivery requirements of the Securities Act and
the registration or qualification requirements of any applicable state
securities Laws. The Company agrees that it will effect the transfer of the
Securities on its books and records upon receipt of an opinion of counsel
stating that 3TEC's proposed sale or transfer of the Securities is exempt from
the registration and qualification requirements of the Securities Act and in
compliance with the Shareholders' Agreement and Agreement of Shareholders.

      SECTION 5.2. Registration, Transfer and Exchange of Warrants. (a) The
Company shall maintain at the offices of the Company as set forth on the
signature pages of this Agreement, the Warrant Register for registration of the
Warrants and Warrant Certificates and transfers thereof. On the Closing Date,
the Company shall register the outstanding Warrants and Warrant Certificates
issued to 3TEC. The Company may deem and treat the registered Warrant Holders as
the absolute owners of the Warrants registered to such Holders and
(notwithstanding any notation of ownership or other writing on the Warrant
Certificates made by any Person) for the purpose of any exercise thereof or any
distribution to the Warrant Holders, and for all other purposes.

            (b) Upon satisfaction of each condition set forth in Section 5.1
hereof, the Company shall register the transfer of any outstanding Warrants in
the Warrant Register upon surrender of the Warrant Certificate(s) evidencing
such Warrants to the Company at the offices of the Company as set forth on the
signature pages of this Agreement, accompanied (if so required by it) by a
written instrument or instruments of transfer in form satisfactory to it, duly
executed by the registered Warrant Holder or by the duly appointed legal
representative thereof. Upon any such registration of transfer, new Warrant
Certificate(s) evidencing such transferred Warrants shall be issued to the
transferee(s) and the surrendered Warrant Certificate(s) shall be canceled. If
less than all the Warrants evidenced by a Warrant Certificate(s) surrendered for
transfer are to be transferred, a new Warrant Certificate(s) shall be issued to
the Warrant Holder surrendering such Warrant Certificate(s) evidencing such
remaining number of Warrants.

            (c) Warrant Certificates may be exchanged at the option of the
Warrant Holder(s) thereof, when surrendered to the Company at the offices of the
Company as set forth on the signature pages of this Agreement, for another
Warrant Certificate or other Warrant Certificates of like tenor and representing
in the aggregate a like number of Warrants. Warrant Certificates surrendered for
exchange shall be canceled.

            (d) No charge shall be made for any such transfer or exchange except
for any Tax or other governmental charge imposed in connection therewith.

      SECTION 5.3. Mutilated or Missing Warrant Certificates. If any Warrant
Certificate shall be mutilated, lost, stolen or destroyed, the Company shall
issue, in exchange and substitution for and upon cancellation of the mutilated
Warrant Certificate, or in lieu of and substitution for the Warrant Certificate
lost, stolen or destroyed, a new Warrant Certificate of like tenor and
representing an equivalent number of Warrants, but only upon receipt of evidence
satisfactory to the Company of such loss, theft or destruction of such Warrant
Certificate and, if requested, indemnity satisfactory to it. No service charge
shall be made for any such substitution, but all expenses and reasonable charges
associated with procuring such indemnity and all stamp, Tax and other
governmental duties that may be imposed in relation thereto shall be borne by
the holder of such Warrant Certificate.

      SECTION 5.4. Registration, Transfer and Exchange of Notes. (a) The Company
shall maintain at the offices of the Company as set forth on the signature pages
of this Agreement, the Note Register for registration of the Notes and transfers
thereof. On the Closing Date, the Company shall register the outstanding Notes
issued to 3TEC. The Company may deem and treat the registered Noteholder as the
absolute owner of the Note registered to such Holder and (notwithstanding any
notation of ownership or other writing on the Note made by any Person) for the
purpose of any exercise thereof or any distribution to the Noteholder, and for
all other purposes.

            (b) Upon satisfaction of each condition set forth in Section 5.1
hereof, the Company shall register the transfer of any outstanding Note in the
Note Register upon surrender of such Note to the Company at the offices of the
Company as set forth on the signature pages of this Agreement, accompanied (if
so required by it) by a written instrument or instruments of transfer in form
satisfactory to it, duly executed by the registered Noteholder or by the duly
appointed legal representative thereof. Upon any such registration of transfer,
a new Note evidencing such transferred Note shall be issued to the transferee
and the surrendered Note shall be canceled. If less than all of the principal
amount of a Note surrendered for transfer is to be transferred, a new Note shall
be issued to the Noteholder surrendering such Note evidencing such remaining
principal balance.

            (c) The Notes may be exchanged at the option of the Noteholders
thereof, when surrendered to the Company at the offices of the Company as set
forth on the signature pages of this Agreement, for another Note or other Notes
of like tenor and representing in the aggregate a like number of Notes. Notes
surrendered for exchange shall be canceled.

            (d) No charge shall be made for any such transfer or exchange except
for any Tax or other governmental charge imposed in connection therewith.

      SECTION 5.5. Mutilated or Missing Notes. If any Note shall be mutilated,
lost, stolen or destroyed, the Company shall issue, in exchange and substitution
for and upon cancellation of the mutilated Note, or in lieu of and substitution
for the Note lost, stolen or destroyed, a new Note of like tenor and
representing the same outstanding principal, but only upon receipt of evidence
satisfactory to the Company of such loss, theft or destruction of such Note and,
if requested, indemnity satisfactory to it. No service charge shall be made for
any such substitution, but all expenses and reasonable charges associated with
procuring such indemnity and all stamp, Tax and other governmental duties that
may be imposed in relation thereto shall be borne by the holder of such Note.

purpose of preparing the Reserve Report, including, without limitation,
production, volumes, sales prices for production, contractual pricing provisions
under oil or gas sales or marketing contracts under hedging arrangements, costs

exploration and development costs supplied to the Reserve Engineers were
prepared in good faith and with a reasonable basis; the information provided to
the Reserve Engineers for purposes of preparing the Reserve Report was prepared

or circumstances that would result in a materially adverse change in the
reserves in the

      SECTION 11.2. No Waivers. No failure or delay by any holder of Securities
in exercising any right, power or privilege hereunder or under any other
Transaction Document shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the

provided shall be cumulative and not exclusive of any rights or remedies
provided by Law or in any of the other Transaction Documents.

      SECTION 11.3. Expenses; Indemnification. (a) Except as provided in Section
6.1(f), all expenses incurred in connection with this Agreement shall be paid by
the party incurring such expenses.

            (b) The Company agrees to indemnify and hold harmless, 3TEC, its
shareholders and each subsequent holder of Securities and their respective
directors, officers, employees, agents, successors and assigns (collectively,
the "Indemnified Parties") from and against any and all liabilities, losses,
damages, costs and expenses of any kind (including, without limitation, the
reasonable fees and disbursements of counsel for the Indemnified Parties in
connection with any investigative, administrative or judicial proceeding,
whether or not any such Indemnified Party shall be designated a party thereto)
which may be incurred by any Indemnified Party relating to or arising out of (a)
this Agreement, the other Transaction Documents, the Closing Transactions and
all other transactions contemplated hereby or thereby.

            (c) The Company further agrees to defend, indemnify and hold
harmless each Indemnified Party from and against any and all losses, liabilities
(including strict liability), damages (including for bodily injury and property
damage), costs, expenses (including attorneys' fees and environmental
consultants' expenses), relating to any of the properties or assets securing the
Obligations, that any Indemnified Party may incur in connection with any
Environmental Complaint or Hazardous Discharge or any violation of any
Environmental Law and Laws regardless of whether or not caused by, or within the
control of, the Company, or any of its Subsidiaries as tenant, sub-tenant or
prior owner or occupant of any of the properties or assets securing the
Obligations or any properties owned or leased by other parties, and regardless
of whether such claim is brought by Governmental Authorities or private parties.
This indemnity shall survive the repayment of the Obligations and the discharge
or release of any Lien granted hereunder or in any other Transaction Document.

            (d) (i) Promptly after receipt by an Indemnified Party of notice of
the commencement of any action, suit or other proceeding against an Indemnified
Party with respect to which an Indemnified Party demands indemnification
hereunder, such Indemnified Party shall promptly notify the Company in writing
of the commencement thereof, provided that the failure to so notify the Company
shall not relieve it from any liability that it may have to an Indemnified
Party, except to the extent that such failure has materially prejudiced the
Company's ability to provide a defense in the proceeding. The Company shall have
the right to assume the defense of any such proceeding, but the Indemnified
Parties collectively shall have the right, at the expense of the Company, to
retain not more than one counsel of their choice to represent the Indemnified
Parties in such proceeding. The counsel for the Indemnified Parties may
participate in, but not control, the defense of such proceeding.

                  (ii) The indemnity provided for herein shall cover the amount
of any settlements entered into by an Indemnified Party in connection with any
claim for which an Indemnified Party may be indemnified hereunder; provided
that, no settlement binding on an Indemnified Party may be made without the
consent of an Indemnified Party and the Company (which consent shall not be
reasonably withheld).

<PAGE>

                  (iii) Any indemnification hereunder shall be made no later
than 45 days after receipt by the Company of the written request of the
Indemnified Party.

            THE PARTIES RECOGNIZE THAT AN INDEMNITEE MAY BE ENTITLED TO
INDEMNIFICATION HEREUNDER FROM ACTS OR OMISSIONS THAT ARISE OUT OF OR RESULT
FROM THE ORDINARY, STRICT, SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH INDEMNITEE.

            (e) 3TEC hereby covenants and agrees with the Company that 3TEC
shall indemnify the Company and hold it harmless from, against and in respect of
any and all costs, losses, claims, liabilities, fines, penalties, damages and
expenses (including interest which may be imposed in connection therewith and
court costs and reasonable fees and disbursements of counsel) incurred by it
resulting from any misrepresentation, breach of warranty or nonfulfillment of
any agreement, covenant or obligation by 3TEC made in this Agreement (including
without limitation any certificate or instrument delivered in connection
herewith.

            SECTION 11.4. Amendments and Waivers; Sale of Interest. Any
provision of this Agreement and the other Transaction Documents may be amended
or waived if, but only if, such amendment or waiver is in writing and is signed
by the Company and (a) the Majority Noteholder and (b) the Majority Warrant
Holder. The Company hereby consents to any participation, sale, assignment,
transfer or other disposition which complies with Article V, at any time or
times hereafter, of any Securities, this Agreement and any of the other
Transaction Documents, or of any portion hereof or thereof, including, without
limitation, 3TEC's rights, title, interests, remedies, powers, and duties
hereunder or thereunder, subject to compliance with applicable Laws and the
provisions of the Compass Senior Debt Documents subject to the requirement that
any such assignee, transferee or purchaser shall agree in writing to become
bound by the terms of this Agreement and the other Transaction Documents. The
Company hereby covenants to notify 3TEC in writing of any amendment proposed to
be made to the Other Securities Purchase Agreements, Other Notes or other
documents relating thereto, and shall allow 3TEC the opportunity to amend this
Agreement and the other Transaction Documents to conform to any such amendments.

            SECTION 11.5. Survival. All representations, warranties and
covenants made by the Company herein or in any certificate or other instrument
delivered by it or in its behalf under the Transaction Documents shall be
considered to have been relied upon by 3TEC and shall survive the delivery to
3TEC of such Transaction Documents and the purchase of the Securities,
regardless of any investigation made by or on behalf of 3TEC. All
representations, warranties and covenants made by 3TEC herein or in any
certificate or other instrument delivered by it or in its behalf under the
Transaction Documents shall be considered to have been relied upon by the
Company and shall survive the delivery to the Company of such Transaction
Documents and the purchase of the Securities, regardless of any investigation
made by or on behalf of the Company.

            SECTION 11.6. Limitation on Interest. Regardless of any provision
contained in the Transaction Documents, no Noteholder shall ever be entitled to
receive, collect, or apply, as interest on the Note, any amount in excess of the
Maximum Lawful Rate, and in the event any Noteholder ever receives, collects or
applies as interest any such excess, such amount which would be deemed excessive
interest shall be deemed a partial prepayment of principal and treated hereunder
as such; and if the Note is paid in full, any remaining excess shall promptly be
paid to the Company. In determining whether or not the interest paid or payable
under any specific contingency exceeds the Maximum Lawful Rate, the Company and
the Noteholder


                                       42
<PAGE>

shall, to the extent permitted under applicable Law, (a) characterize any
nonprincipal payment as an expense, fee or premium rather than as interest, (b)
exclude voluntary prepayments and the effects thereof, and (c) amortize,
prorate, allocate and spread, in equal parts, the total amount of the interest
throughout the entire contemplated term of the Note, so that the interest rate
is the Maximum Lawful Rate throughout the entire term of the Note; provided,
however, that, if the unpaid principal balance thereof is paid and performed in
full prior to the end of the full contemplated term thereof, and if the interest
received for the actual period of existence thereof exceeds the Maximum Lawful
Rate, the Noteholder shall refund to the Company the amount of such excess and,
in such event, the Noteholder shall not be subject to any penalties provided by
any Laws for contracting for, charging, taking, reserving or receiving interest
in excess of the Maximum Lawful Rate.

            SECTION 11.7. Invalid Provisions. If any provision of the
Transaction Documents is held to be illegal, invalid, or unenforceable under
present or future Laws effective during the term thereof, such provision shall
be fully severable, the Transaction Documents shall be construed and enforced as
if such illegal, invalid, or unenforceable provision had never comprised a part
thereof, and the remaining provisions thereof shall remain in full force and
effect and shall not be affected by the illegal, invalid, or unenforceable
provision or by its severance therefrom. Furthermore, in lieu of such illegal,
invalid, or unenforceable provision there shall be added automatically as a part
of the Transaction Documents a provision as similar in terms to such illegal,
invalid, or unenforceable provision as may be possible and be legal, valid and
enforceable.

            SECTION 11.8. Successors and Assigns. The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Company may not
assign or otherwise transfer any of its rights or obligations under this
Agreement. Notwithstanding any other provision herein, 3TEC may assign its
rights to its Affiliates, subject to compliance with applicable Laws.

            SECTION 11.9. GOVERNING LAW. THIS AGREEMENT AND THE TRANSACTION
DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE
STATE OF TEXAS.

            SECTION 11.10. Counterparts. This Agreement may be signed in any
number of counterparts, each of which shall be an original, with the same effect
as if the signatures thereto and hereto were upon the same instrument.

            SECTION 11.11. No Third Party Beneficiaries. Except as provided in
Section 11.3, it is expressly intended that there shall be no third party
beneficiaries of the covenants, agreements, representations or warranties herein
contained other than transferees or assignees of all or any part of 3TEC's
interest hereunder.

            SECTION 11.12. FINAL AGREEMENT. THIS AGREEMENT AND THE OTHER
TRANSACTION DOCUMENTS COLLECTIVELY REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS BETWEEN THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

VENUE. ANY SUIT, ACTION OR PROCEEDING BROUGHT BY 3TEC WITH RESPECT TO THIS
AGREEMENT OR ANY OF THE OTHER TRANSACTION DOCUMENTS MAY BE BROUGHT IN THE COURTS
OF THE STATE OF TEXAS, COUNTY OF DALLAS, OR IN THE FEDERAL COURTS LOCATED IN THE

                       SENIOR SUBORDINATE PROMISSORY NOTE

THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THIS NOTE
MAY NOT BE TRANSFERRED EXCEPT PURSUANT TO A VALID EXEMPTION COVERING SUCH
TRANSFER.

$10,700,000                      Dallas, Texas               _____________, 1999

      FOR VALUE RECEIVED, the undersigned, MIDDLE BAY OIL COMPANY, INC, an
Alabama corporation ("Maker" or the "Company") hereby promises to pay to the
order of 3TEC ENERGY CORPORATION, a Delaware corporation ("Payee"), not later
than 2:00 P.M. (Dallas, Texas time), on the date when due, in Federal or other
funds immediately available in Dallas, Texas, at Payee's offices at 5910 N.
Central Expressway, Suite 1150, Dallas, Texas 75206 or such other address, given
to Maker by Payee, the principal sum of TEN MILLION SEVEN HUNDRED THOUSAND AND
NO/100 DOLLARS ($10,700,000), together with interest, as hereinafter described.
Whenever any payment of principal of, or interest on, this Note shall be due on
a day which is not a Business Day, the date for payment thereof shall be
extended to the next succeeding Business Day. If the date for payment of
principal is extended by operation of law or otherwise, interest thereon shall
be payable for such extended time.

      This Note has been executed and delivered pursuant to, and is subject to
and governed by, the terms of that certain Securities Purchase Agreement dated
as of _____________, 1999, by and between Maker and Payee (the "Agreement").
This Note is the "Note" referred to in the Agreement. Unless otherwise defined
herein or unless the context hereof otherwise requires, each term used herein
with its initial letter capitalized has the meaning given to such term in the
Agreement.

      This Note shall rank senior in right of payment to all Company notes and
indebtedness other than the Compass Senior Debt. This Note shall rank pari passu
with the Other Notes without any preference or priority one over another.

      Maker reserves the right to prepay without premium or penalty, after
thirty (30) days prior written notice to the Noteholder, the principal amount of
the Note, in whole or in part, at any time after _________, 2001.

      Maker promises to pay interest on the outstanding principal balance
hereof, prior to the occurrence of an Event of Default, at a rate per annum
equal to the lesser of (a) the Fixed Rate or (b) the Maximum Lawful Rate, in
Federal or other funds immediately available in Dallas, Texas, at the offices of
Payee above referenced. Interest shall accrue on the principal balance of the
Note outstanding from time to time at the Fixed Rate; provided, that, interest
shall accrue on any amounts past due and owing on the Note from the date due
until paid at the Default Rate; provided further, that in no event shall the
rate of interest charged hereunder exceed the Maximum Lawful Rate. Interest
shall be payable on the Note as it accrues on ___, 1999 and continuing on each
___, ___, ___ and ___ thereafter until maturity. Whenever any payment of
principal of, or interest on, the Note shall be due on a day which is not a
Business Day, the date for payment thereof shall be extended to the next
succeeding Business Day.
<PAGE>

      With respect to the first eight (8) quarterly interest payments payable
hereunder commencing with the first such quarterly interest payment, the Company
may, at least thirty (30) days prior to the subject payment date, elect to
accrue and add to the principal of the Note up to fifty percent (50%) of the
interest payment due and payable on such interest payment date. If such an
election is made, the Company shall notify the Noteholder of the portion (up to
50%) of such quarterly interest payment which the Company elects to accrue and
add to the principal of the Note.

      Interest shall be computed on the Note on the basis of the number of
actual days elapsed, assuming that each calendar year consisted of 360 days. The
entire outstanding principal balance of this Note and all accrued but unpaid
interest thereon shall be due and payable in full in a single installment on
_____________, 2004.

      The entire outstanding principal balance of the Note and all accrued but
unpaid interest thereon shall be immediately due and payable in full upon the
occurrence of a Change of Control.

      A Noteholder may elect to convert all or any portion of the amount of
principal and accrued but unpaid interest on the Note as hereinafter provided.
Each $3.00 (the "Conversion Price") of principal and accrued but unpaid interest
on the Note shall be convertible into one share of Common Stock. The Conversion
Price is subject to adjustment from time to time upon the occurrence of any of
the events enumerated below:

      1.    In the event that the Company shall (a) declare a dividend on the
            Common Stock in shares of its capital stock (whether shares of such
            Common Stock or of capital stock of any other class of the Company),
            (b) split or subdivide the outstanding Common Stock, or (c) combine
            the outstanding Common Stock into a smaller number of shares, then
            (as a result of an event described in (a), (b) or (c)) the
            Conversion Price shall be adjusted to equal the product of the
            Conversion Price in effect immediately prior to such event
            multiplied by a fraction the numerator of which is equal to the
            number of shares of Common Stock outstanding on a Fully Diluted
            Basis (as defined below) immediately after the event and the
            denominator of which is equal to the number of shares of Common
            Stock outstanding on a Fully Diluted Basis immediately prior to such
            event.
<PAGE>

      2.    In the event that the Company shall (a) issue any shares of Common
            Stock without consideration or at a price per share less than the
            Conversion Price immediately prior to such issuance, or (b) issue
            options, rights or warrants to subscribe for or purchase such Common
            Stock (or securities convertible into such Common Stock) without
            consideration or at a price per share (or having a conversion price
            per share, if a security convertible into such Common Stock) less
            than the Conversion Price, then, effective upon such issuance, the
            Conversion Price shall be adjusted to equal the product obtained by
            multiplying the Conversion Price in effect immediately prior to the
            date of such issuance by a fraction, the numerator of which shall be
            the number of shares of Common Stock outstanding on a Fully Diluted
            Basis immediately prior to such issuance plus the number of shares
            of Common Stock which the aggregate offering price of the total
            number of shares of such Common Stock so to be issued or to be
            offered for subscription or purchase (or the aggregate initial
            conversion price of the convertible securities so to be offered)
            would purchase at the Conversion Price immediately prior to such
            issuance, and the denominator of which shall be the number of shares
            of Common Stock outstanding on a Fully Diluted Basis immediately
            after such issuance. In case such consideration may be paid in a
            consideration part or all of which shall be in a form other than
            cash, the value of such consideration shall be as determined by an
            investment banking firm reasonably acceptable to the Noteholder (the
            cost of the engagement of said investment banking firm to be borne
            by the Company). Shares of such Common Stock owned by or held for
            the account of the Company or any Subsidiary thereof shall not be
            deemed outstanding for the purpose of any such computation. Such
            adjustment shall be made successively whenever the date of such
            issuance is fixed (which date of issuance shall be the record date
            for such issuance if a record date therefor is fixed); and, in the
            event that such shares or options, rights or warrants are not so
            issued, the Conversion Price shall again be adjusted to be the
            Conversion Price if the date of such issuance had not been fixed.

      3.    In case the Company shall make a distribution to all holders of
            Common Stock (including any such distribution made in connection
            with a consolidation or merger in which the Company is the surviving
            corporation) of shares of it stock, evidences of its indebtedness,
            assets, or rights, options or warrants (other than those referred to
            in paragraph 2 above) to subscribe for or purchase such shares,
            evidences of indebtedness, or assets, then, effective upon such
            distribution, the Conversion Price shall be adjusted to equal the
            product obtained by multiplying the Conversion Price in effect
            immediately prior to the date of such distribution by a fraction,
            the numerator of which shall be the Per Share Stock Price for the
            trading day immediately preceding the day of distribution
            ("Pre-Distribution Price") less the fair market value of the
            distribution (as determined in good faith by the Board of Directors
            of the Company) applicable to one share of Common Stock, and the
            denominator of which shall be the Pre-Distribution Price. Such
            adjustment shall be made successively whenever a date for such
            distribution is fixed (which date of distribution shall be the
            record date for such issuance if a record date therefor is fixed);
            and, if such distribution is not so made, the Conversion Price shall
            again be adjusted to be to be the Conversion Price if the date of
            such issuance had not been fixed.
<PAGE>

      4.    No adjustment in the Conversion Price shall be required unless such
            adjustment would require an increase or decrease of at least
            one-tenth of one percent (.1%) in the total number of shares of
            Common Stock that would be issued as a result of the conversion of
            all the Note; provided that any adjustments which by reason of this
            section are not required to be made shall be carried forward and
            taken into account in any subsequent adjustment. All calculations
            under this section shall be made to the nearest hundredth of one
            percent.

      5.    In the event of any capital reorganization of the Company, or of any
            reclassification of any Common Stock for which the Note is
            convertible (other than a subdivision or combination of outstanding
            shares of such Common Stock), or in case of the consolidation of the
            Company with or the merger of the Company with or into any other
            corporation or of the sale of the properties and assets of the
            Company as, or substantially as, an entirety to any other entity,
            each $3.00 of principal and unpaid interest outstanding of the Note
            shall after such capital reorganization, reclassification of such
            Common Stock, consolidation, merger or sale be convertible, upon the
            terms and conditions specified in this Agreement, into the number of
            shares of stock or other securities or assets to which a holder of
            the number of shares of Common Stock into which amount of principal
            and interest payable under the Note is convertible (at the time of
            such capital reorganization, reclassification of such Common Stock,
            consolidation, merger or sale) would have been entitled upon such
            capital reorganization, reclassification of such Common Stock,
            consolidation, merger or sale; and in any such case, if necessary,
            the provisions set forth in this section with respect to the rights
            thereafter of such Note shall be appropriately adjusted so as to be
            applicable, as nearly as may reasonably be, to any shares of stock
            or other securities or assets thereafter deliverable upon the
            conversion of the Note. The Company shall not effect any such
            consolidation, merger or sale, unless prior to or simultaneously
            with the consummation thereof, the successor corporation (if other
            than the Company) resulting from such consolidation or merger or the
            corporation purchasing such assets or the appropriate corporation or
            entity shall assume, by written instrument, the obligation to
            deliver to the Noteholder the shares of stock, securities or assets
            to which, in accordance with the foregoing provisions, such
            Noteholder may be entitled pursuant to this section.

      6.    If any question shall at any time arise with respect to the
            Conversion Price or the number of shares issuable upon conversion of
            the Note, such question shall be determined by the independent firm
            of certified public accountants of recognized national standing
            selected by the Noteholder and acceptable to the Company.

      7.    Notwithstanding anything in this section to the contrary, the
            Company shall not be permitted to take any action described in this
            section, if such action is prohibited under any other provision of
            this Note or the Agreement.

      If a Noteholder elects to convert all or a portion of the outstanding
principal and accrued and unpaid interest under the Note, then the Noteholder
shall deliver the Note to the Company in exchange for an amended and restated
note setting forth the new amount of principal and accrued and unpaid interest.
Upon such exchange, the Company shall promptly issue and deliver, or cause to be
issued and delivered, to the Noteholder a certificate or certificates for the
number of whole shares of Common Stock to which the Noteholder is entitled under
the terms hereof. To the extent permitted by law, such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such exchange of the Notes for the amended and restated note and Conversion
Shares, and the Noteholder shall be treated for all purposes as the record
holder of such shares of Common Stock on such date.

      No fractional shares or script of Common Stock shall be issued upon
conversion of all or a portion of the outstanding principal and accrued unpaid
interest of the outstanding principal and accrued unpaid interest under the
Note. In lieu of a fractional share of Common Stock to which the holder would
otherwise be entitled, the Company shall pay cash equal to the product of such
fraction multiplied by the market value of one share of Common Stock on the date
of conversion.

      Upon the occurrence and during the continuance of an Event of Default, and
upon the conditions stated in the Agreement, the holder hereof may, at its
option, declare the entire unpaid principal of and accrued interest on this Note
immediately due and payable (provided that, upon the occurrence of certain
Events of Default, and upon the conditions stated in the Agreement, such
acceleration shall be automatic), without notice, demand, or presentment, all of
which are hereby waived, and the holder hereof shall have the right to offset
against this Note any sum or sums owed by the holder hereof to Maker. After the
occurrence of an Event of Default, interest shall accrue on the outstanding
principal balance of this Note and, to the extent permitted by applicable Law,
on accrued but unpaid interest, at the lesser of (a) the Default Rate or (b) the
Maximum Lawful Rate.

      After the occurrence of an Event of Default, all amounts collected or
received by any Noteholder in respect of the Obligations shall be applied first,
to the payment of all proper costs incurred by the Noteholder in connection with
the collection thereof (including reasonable fees, expenses and disbursements of
counsel for the Noteholder), second, to the reimbursement of any advances made
by Noteholder to effect performance of any unperformed covenants of the Company
under any of the Transaction Documents, third, to the payment of all accrued
interest on the Note, fourth, to unpaid principal on the Note, and fifth to the
Company or any other Person entitled to such proceeds under applicable Law.

      If this Note is placed in the hands of an attorney for collection, or if
it is collected through any legal proceedings, Maker agrees to pay the court
costs, reasonable attorneys' fees, and other costs of collection of the holder
hereof.

      Maker, and each surety, endorser, guarantor, and other party ever liable
for payment of any sums of money payable on this Note, jointly and severally
waive presentment and demand for payment, protest, notice of protest and
nonpayment, and notice of acceleration and the intention to accelerate, and
agree that their liability on this Note shall not be affected by any renewal or
extension in the time of payment hereof, by any indulgences, or by any release
or change in any security for the payment of this Note, and hereby consent to
any and all renewals, extensions, indulgences, releases, or changes, regardless
of the number of such renewals, extensions, indulgences, releases or changes.

      Section 2. Independent Registration Rights.

      2.1 The Corporation hereby grants to each Shareholder separate rights to
require the Corporation to use its best efforts to cause registration and sale
in a public offering of all or a portion of such Shareholder's Registrable
Securities in accordance with this Section 2; provided, however, the Corporation
shall not have any obligation to effect more than a total of three (3) effective
registrations pursuant to this Section 2 at the Corporation's expense. If the
Corporation shall have received a written request submitted by Shareholder(s)
owning at least a majority of the Registrable Securities outstanding at the time
of such request (the "Requisite Holders") that such Shareholder(s)
desires/desire to sell Registrable Securities and specifying the number of
Registrable Securities proposed to be sold (for the purposes of this Section 2,
"Shares") and the proposed plan for distribution of the Shares, Corporation will
thereafter:

            2.1.1 Give prompt (but in any event within fifteen (15) days after
the receipt of the Requisite Holder(s)' notice) notice to all other Shareholders
of such notice and of such other Shareholders' rights to have their Registrable
Securities included in such registration.

            2.1.2 Upon the request of any such Shareholder made within fifteen
(15) days after the receipt by such Shareholder of any such notice given
pursuant to subsection 2.1.1 (which request shall specify the Registrable
Securities intended to be disposed of by such Shareholder and the intended
method or methods of disposition thereof), the Corporation will use its best
efforts to effect the registration of all Shares which the Corporation has been
so requested to register pursuant to this subsection 2.1.

            2.1.3 Prepare and file as soon as practicable, but in no event later
than thirty (30) days from Corporation's receipt of the last Shareholder's
request to have such Shareholder's Registrable Securities included in such
registration within the time period specified in Section 2.1.2, a registration
statement under the Securities Act of 1933, as amended (the "Securities Act")
("Registration Statement") with the Securities Exchange Commission
("Commission") on Form S-1 (or Form S-2 or Form S-3, if Corporation is entitled
to use such forms, or similar forms available for use by small business issuers)
and use its best efforts to cause such Registration Statement to


                                       2
<PAGE>

become effective in order that the Shareholders may sell the Shares in
accordance with the proposed plan of distribution.

            2.1.4 Prepare and file with the Commission such amendment and
supplements to such Registration Statement and prospectus used in connection
therewith including any preliminary prospectus or supplemental or amended
prospectus (the "Prospectus") as may be necessary to keep such Registration
Statement continuously effective and to comply with the provisions of the
Securities Act with respect to the offer of the Shares during the period
required for distribution of the Shares, which period shall not be in excess of
the earlier of (i) one year from the effective date of such Registration
Statement, and (ii) the distribution of all Shares covered by such Registration
Statement.

            2.1.5 Furnish to each Shareholder such number of copies of the
Prospectus (including any preliminary prospectus or supplemental or amended
prospectus ) as such Shareholder may reasonably request in order to facilitate
the sale and distribution of the Shares.

      2.2 The right of each Shareholder to register Shares pursuant to the
provisions of this Section 2 shall be subject to the condition that if a request
for registration is made within sixty (60) days prior to the conclusion of
Corporation's then current fiscal year, Corporation shall have the right to
delay the filing of the Registration Statement for such period of time until
Corporation receives its audited financial statements for such fiscal year.

      2.3 If the Requisite Holder(s) intend/intends to distribute the
Registrable Securities covered by the notice pursuant to subsection 2.1 by means
of an underwriting, the Requisite Holder(s) shall so advise the Corporation as a
part of the notice made pursuant to subsection 2.1 and provide the name of the
managing underwriter or underwriters that the Requisite Holder(s)
proposes/propose to employ in connection with the public offering proposed to be
made pursuant to the registration requested. If the managing underwriter of such
underwritten offering shall inform the Corporation and the Shareholders
requesting that their Shares be registered pursuant to this Section 2 by letter
of its belief that the amount of Shares requested to be included in such
registration exceeds the amount which can be sold in (or during the time of)
such offering within a price range acceptable to the Requisite Holders, then the
Corporation will include in such registration such amount of Shares which the
Corporation is so advised can be sold in (or during the time of) such offering
pro rata on the basis of the amount of such Shares so proposed to be sold and so
requested to be included by such parties.

      2.4 A registration shall not be deemed to have been effected (i) unless it
has become effective and remained effective for the period specified in
subsection 2.1.4, (ii) if, after it has become effective, such registration is
terminated by a stop order, injunction or other order of the Commission or other
governmental agency or court, or (iii) if the conditions to closing specified in
any purchase agreement or underwriting agreement entered into in connection with
such registration are not satisfied for any reason, other than as a result of
the voluntary termination of such offering by the Requisite Holders.

      Section 3. Piggy-Back Registration Rights.

      3.1 If Corporation proposes to file, on its behalf, a Registration
Statement under the Securities Act on Form S-1, S-2 or S-3 or similar forms
available for use by small business issuers, other than pursuant to Section 2 of
this Agreement or in connection with a dividend reinvestment, employee stock
purchase, option or similar plan or in connection with a merger, consolidation
or reorganization, Corporation shall give written notice to each Shareholder and
Piggy-Back Shareholder at least thirty (30) days before the filing with the
Commission of such Registration Statement. Such notice shall offer to include in
such filing all or a portion of the Registrable Securities and Piggy-Back
Registrable Securities owned by such Shareholder or Piggy-Back Shareholder. If a
Shareholder or Piggy-Back Shareholder desires to include all or a portion of its
Registrable Securities or Piggy-Back Registrable Securities in such Registration
Statement, it shall give written notice to Corporation within fifteen (15) days
after the date of mailing of such offer specifying the amount of Registrable
Securities and/or Piggy-Back Registrable Securities to be registered (for the
purpose of this Section 3, "Shares"). Corporation shall thereupon include in
such filing the Shares, subject to priorities in registration set forth in this
Agreement, and subject to its right to withdraw such filing, and shall use its
best efforts to effect registration under the Securities Act of the Shares.

      3.2 The right of the Shareholders and the Piggy-Back Shareholders to have
the Shares included in any Registration Statement in accordance with the
provisions of this Section 3 shall be subject to the following conditions:

            3.2.1 Corporation shall have the right to require that each
Shareholder or PiggyBack Shareholder agree to refrain from offering or selling
any shares of Common Stock that it owns which are not included in any such
Registration Statement in accordance with this Section 3 for any reasonable time
period specified, not to exceed ninety (90) days, by any managing underwriter of
the offering to which such Registration Statement relates.

            3.2.2 If (i) a registration pursuant to this Section 3 involves an
underwritten offering of the securities being registered to be distributed (on a
firm commitment basis) by or through one or more underwriters of recognized
standing under underwriting terms appropriate for such a transaction and (ii)
the managing underwriter of such underwritten offering shall inform the
Corporation and the Shareholders and Piggy-Back Shareholders who have requested
that their Shares be registered pursuant to this Section 3 by letter of its
belief that the amount of Shares requested to be included in such registration
exceeds the amount which can be sold in (or during the time of) such offering
within a price range acceptable to a majority of such requesting holders, then
the Corporation will include in such registration such amount of securities
which the Corporation is so advised can be sold in (or during the time of) such
offering as follows: first, the securities being offered by the Corporation for
its own account; second such Shares of the Shareholders which are requested to
be included in such registration pro rata on the basis of the amount of such
Shares so


                                       4
<PAGE>

proposed to be sold and so requested to be included by such Shareholders; and
third, such Shares of the Piggy-Back Shareholders and which are requested to be
included in such registration pro rata on the basis of the amount of such Shares
so proposed to be sold and so requested to be included by such Piggy-Back
Shareholders.

            3.2.3 Corporation shall furnish each Shareholder and Piggy-Back
Shareholder with such number of copies of the Prospectus as such Shareholder or
Piggy-Back Shareholder may reasonably request in order to facilitate the sale
and distribution of its shares.

      3.3 Notwithstanding the foregoing, Corporation in its sole discretion may
determine not to file the Registration Statement or proceed with the offering as
to which the notice specified herein is given without liability to the
Shareholders or the Piggy-Back Shareholders.

      Section 4. Participation in Underwritten Registrations. No Shareholder or
Piggy-Back Shareholder may participate in any registration hereunder which
relates to an underwritten offering unless such Shareholder or Piggy-Back
Shareholder (a) agrees to sell such holder's securities on the basis provided in
any underwriting arrangements approved by the holders of at least a majority of
the Registrable Securities and Piggy-Back Registrable Securities to be included
in such registration, or by a Person appointed by such holders to act on their
behalf to approve such arrangements, and (b) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting
arrangements.

      Section 5. Exclusive Registration Rights and Transfer.

      The rights of each Shareholder under this Agreement may upon notice to the
Corporation be transferred to its respective Affiliates in combination with a
transfer of shares to such Affiliates. In addition, the rights of each
Shareholder under this Agreement may upon notice to the Corporation be
transferred to a non-Affiliate transferee in combination with a transfer of
shares to such non-Affiliate transferee. However, such non-Affiliate transferee
may not thereafter transfer its rights under this Agreement without the
Corporation's written consent. Except as provided in this Section 5, the rights
granted under this Agreement are granted specifically to and for the benefit of
each Shareholder and Piggy Back Shareholder and shall not pass to any transferee
of Registrable Securities. From and after the date of this Agreement, the
Corporation will not, without the prior written consent of Shareholders holding
at least a majority of the Registrable Securities then outstanding, enter into
any agreement with respect to its securities which is inconsistent with or
violates the rights granted to the Shareholders in this Agreement. Without
limiting the foregoing, the Corporation also specifically agrees that during the
period commencing on the date hereof and ending when the Shareholders have
disposed of all of their Registrable Securities, the Corporation will not enter
into an agreement with any party pertaining to the registration by the
Corporation of such party's Common Stock. The Corporation represents and
warrants to each of the Shareholders


                                       5
<PAGE>

that, as of the date hereof, the Corporation is not a party to any agreement,
other than this Agreement, pertaining to the registration by the Corporation of
Common Stock.

      Section 6. Expenses. Corporation will bear all the expenses in connection
with any Registration Statement under this Agreement, other than transfer taxes
payable on the sale of such shares, the fees and expenses of counsel to the
Shareholders and Piggy-Back Shareholders and fees and commissions of brokers,
dealers and underwriters.

      Section 7. Recall of Prospectuses, etc. With respect to a Registration
Statement or amendment thereto filed pursuant to this Agreement, if, at any
time, Corporation notifies the Shareholders and Piggy-Back Shareholders that an
amendment or supplement to such Registration Statement or amendment to the
Prospectus included therein is necessary or appropriate, each Shareholder and
Piggy-Back Shareholder will forthwith cease selling and distributing shares
thereunder and will forthwith redeliver to Corporation all copies of such
Registration Statement and Prospectuses then in its possession or under its
control. Corporation will use its best efforts to cause any such amendment or
supplement to become effective as soon as practicable and will furnish each
Shareholder and Piggy-Back Shareholder with a reasonable number of copies of
such amended or supplemented prospectus (and the period during which Corporation
is required to use its best efforts to maintain such Registration Statement in
effect pursuant to this Agreement will be increased by the period from the date
on which such Shareholder or Piggy-Back Shareholder ceased selling and
distributing shares thereunder to the date on which such amendment or supplement
becomes effective).

      Section 8. Cooperation with Existing Shareholders. Corporation shall be
entitled to require the Shareholders and Piggy-Back Shareholders to cooperate
with Corporation in connection with a registration of Registrable Securities
pursuant to this Agreement and furnish (i) such information as may be required
by Corporation or the Commission in connection therewith and (ii) such
representations, undertakings and agreements as may be required by the
Commission in connection therewith.

      Section 9. Registration Procedures Upon the receipt of a request for
registration of any Registrable Securities pursuant to Section 2 or Section 3 of
this Agreement, Corporation will use its best efforts to effect the registration
of the Registrable Securities in accordance with the intended method of
disposition thereof, and pursuant thereto Corporation will as expeditiously as
possible:

      9.1.1 Prepare and file with the Commission a registration statement on an
appropriate form under the Securities Act and use its best efforts to cause such
registration statement to become


                                       6
<PAGE>

effective; provided, that before filing a registration statement or prospectus
or any amendments or supplements thereto, including documents incorporated by
reference after the initial filing of any registration statement, Corporation
will promptly furnish to the holders of Registrable Securities and Piggy-Back
Registrable Securities to be registered and sold pursuant to this Agreement (the
"Registered Holders") and the underwriters, if any, copies of all such documents
proposed to be filed, which documents will be subject to the review of the
Registered Holders and the underwriters, and Corporation will not file any
registration statement or amendment thereto, or any prospectus or any supplement
thereto (including such documents incorporated by reference) to which the
Registered Holders or the underwriters, if any, shall reasonably object in the
light of the requirements of the Securities Act and any other applicable laws
and regulations.

      9.1.2 Prepare and file with the Commission such amendments and
post-effective amendments to a registration statement as may be necessary to
keep such registration statement effective for the applicable period; cause the
related prospectus to be filed pursuant to Rule 424(b) (or any successor
provision) under the Securities Act; cause such prospectus to be supplemented by
any required prospectus supplement and, as so supplemented, to be filed pursuant
to Rule 424(b) (or any successor provision) under the Securities Act; and comply
with the provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement during the applicable period
in accordance with the intended methods of disposition set forth in such
registration statement or supplement to such prospectus.

      9.1.3 Notify the Registered Holders and the managing underwriters, if any,
promptly, and (if requested by any such person) confirm such advice in writing,
(i) when a prospectus or any prospectus supplement or post-effective amendment
has been filed, and, with respect to a registration statement or any
post-effective amendment, when the same has become effective, (ii) of any
request by the Commission for amendments or supplements to a registration
statement or related prospectus or for additional information, (iii) of the
issuance by the Commission of any stop order suspending the effectiveness of a
registration statement or the initiation of any proceeding for that purpose,
(iv) if at any time the representations and warranties of Corporation
contemplated by subsection 9.1.10 cease to be true and correct, (v) of the
receipt by Corporation of any notification with respect to the suspension or
qualification of any of the Registrable Securities for sale in any jurisdiction
or the initiation of any proceeding for such purpose, (vi) of the happening of
any event which requires the making of any changes in a registration statement
or related prospectus so that such documents will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading and
(vii) of Corporation's reasonable determination that a post-effective amendment
to a registration statement would be appropriate or that there exist
circumstances not yet disclosed to the public which make further sales under
such registration statement inadvisable pending such disclosures and
post-effective amendment.

      9.1.4 Make reasonable efforts to obtain the withdrawal of any order
suspending the effectiveness of a registration statement, or the lifting of any
suspension of the qualification of any of the Registrable Securities for sale in
any jurisdiction, at the earliest possible moment.

      9.1.5 If requested by the managing underwriters or the Registered Holders
in connection with an underwritten offering, immediately incorporate in a
prospectus supplement or post effective amendment such information as the
managing underwriters and the Registered Holders agree should be included
therein relating to such sale and distribution of Registrable Securities,
including, without limitation, information with respect to the number of shares
of Registrable Securities being sold to such underwriters and the purchase price
being paid therefor by such underwriters and with respect to any other terms of
the underwritten (or best efforts underwritten) offering of the Registrable
Securities to be sold in such offering; make all required filings of such
prospectus supplement or post-effective amendment as soon as notified of the
matters to be incorporated in such prospectus supplement or post-effective
amendment; and supplement or make amendments to any registration statement if
requested by the Registered Holders or any underwriter of such Registrable
Securities.

      9.1.6 Furnish to the Registered Holders and each managing underwriter, if
any, without charge, at least one signed copy of the registration statement, any
post-effective amendment thereto, including financial statements and schedules,
all documents incorporated therein by reference and all exhibits (including
those incorporated by reference).

      9.1.7 Deliver without charge to the Registered Holders and the
underwriters, if any, as many copies of the prospectus or prospectuses
(including each preliminary prospectus) and any amendment or supplement thereto
as such persons may reasonably request; and Corporation consents to the use of
such prospectus or any amendment or supplement thereto by such Registered
Holders and the underwriters, if any, in connection with the offer and sale of
the Registrable Securities covered by such prospectus or any amendment or
supplement thereto.

      9.1.8 Prior to any public offering of Registrable Securities, register or
qualify or cooperate with the Registered Holders, the underwriters, if any, and
respective counsel in connection with the registration or qualification of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions as the Registered Holders or an underwriter reasonably
requests in writing; keep each such registration or qualification effective
during the period such registration statement is required to be kept effective
and do any and all other acts or things necessary or advisable to enable the
disposition in such jurisdictions of the Registrable Securities covered by the
applicable registration statement; provided, however, that Corporation will not
be required in connection therewith or as a condition thereto to qualify
generally to do business or subject itself to general service of process in any
such jurisdiction where it is not then so subject.

      9.1.9 Upon the occurrence of any event contemplated by subsection 9.1.3
(ii) - (vii) above, prepare, to the extent required, a supplement or
post-effective amendment to the applicable registration statement or related
prospectus or any document incorporated therein by reference or file any other
required document so that, as thereafter delivered to the purchaser of the
Registrable Securities being sold thereunder, such prospectus will not contain
an untrue statement of a material fact or omit to state any material fact
necessary to make the statements therein not misleading.

<PAGE>

of Corporation's first fiscal quarter next succeeding each sale of Registrable
Securities after the effective date of a registration statement, which
statements shall cover said 12-month periods.

      9.1.13 If Corporation, in the exercise of its reasonable judgment, objects
to any change reasonably requested by the Registered Holders or the
underwriters, if any, to any registration statement or prospectus or any
amendments or supplements thereto (including documents incorporated or to be
incorporated therein by reference) as provided for in this Section 9,
Corporation shall not be obligated to make any such change and such Registered
Holders may withdraw their Registrable Securities from such registration, in
which event (i) Corporation shall pay all registration expenses (including its
counsel fees and expenses) incurred in connection with such registration
statement or amendment thereto or prospectus or supplement thereto, and (ii) in
the case of a registration being effected pursuant to Section 2, such
registration shall not count as one of the registrations Corporation is

      Section 10. Indemnification.

      10.1 In the event of any registration of any securities under the
Securities Act pursuant to this Agreement, Corporation will indemnify and hold
harmless each Shareholder, each Piggy-Back Shareholder, any underwriter and each
other Person, if any, who controls such Shareholder, Piggy- Back Shareholder or
underwriter within the meaning of the Securities Act, against any losses,
claims, damages or liabilities, joint or several, to which each such
Shareholder, Piggy-Back Shareholder or any underwriter may become subject, under
the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or action in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
such Registration Statement or preliminary prospectus (if used prior to the
effective date of such Registration Statement) or final or summary prospectus
contained therein (if used during the period the Corporation is required to keep
the Registration Statement effective), or any amendment or supplement thereto,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements made therein not misleading, and will reimburse each such
Shareholder, Piggy-Back Shareholder or underwriter for any legal or any other
expenses as reasonably incurred by such person in connection with investigating
or defending any such action or claim, excluding any amounts paid in settlement
of any litigation, commenced or threatened, if such settlement is effected
without prior written consent of Corporation; provided, however, that
Corporation will not be liable to the Shareholders, Piggy-Back Shareholders or
an underwriter in any such case to the extent that any such loss, claim, damage,
liability or expense arises out of or is based upon an untrue statement or
omission or alleged omission made in said Registration Statement, said
preliminary prospectus or said final or summary prospectus or any amendment or
supplement thereto, in reliance upon and in conformity with written information
furnished to Corporation by that Shareholder, Piggy-Back Shareholder or their
respective affiliates or representatives, or by that underwriter, as the case
may be, specifically for use in the preparation thereof; and provided further
that the indemnity agreement contained in this Section 10 with respect to any
preliminary prospectus shall not inure to the benefit of the Shareholders,
Piggy-Back Shareholders or any underwriter or to


                                       10
<PAGE>

any Person selling the same in respect of any loss, claim, damage, liability or
action asserted by someone who purchased shares from such person if a copy of
the final prospectus (as the same may be amended or supplemented) in connection
with such registration statement was not sent or given to such person with or
prior to written confirmation of the sale and if the untrue statement or
omission or alleged untrue statement or omission of a material fact contained in
such preliminary prospectus was corrected in the final prospectus.

      10.2 In the event of any registration of securities under the Securities
Act pursuant to this Agreement, each Shareholder and Piggy-Back Shareholder will
indemnify and hold harmless Corporation, each of its directors and officers, any
underwriter and each other Person, if any, who controls Corporation or
underwriter within the meaning of the Securities Acts, against any losses,
claims, damages or liabilities, joint or several, to which Corporation or any
such director, officer, underwriter may become subject, under the Securities Act
or otherwise, insofar as such losses, claims, damages or liabilities (or action
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in such Registration
Statement or preliminary prospectus or final or summary prospectus contained
therein, or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements made therein not
misleading, and will reimburse Corporation, each such director, officer,
underwriter for any legal or any other expenses as reasonably incurred by them
in connection with investigating or defending any such action or claim,
excluding any amounts paid in settlement of any litigation, commenced or
threatened, if such settlement is effected without prior written consent of the
indemnifying Shareholder, Piggy-Back Shareholder or their respective
representative; but in all cases only if, and to the extent that any such loss,
claim, damage, liability or expense arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission therein
made in reliance upon and in conformity with written information furnished to
Corporation by the indemnifying Shareholder, Piggy-Back Shareholder or their
respective affiliates or representatives specifically for use in the preparation
thereof. Notwithstanding the foregoing, the amount of the indemnity provided by
each such Shareholder or Piggy-Back Shareholder pursuant to this Section 10
shall not exceed the net proceeds received by such Shareholder or Piggy-Back
Shareholder in such related registration and sale.

      10.3 Promptly after receipt by a party entitled to indemnification under
subsection 10.1 or 10.2 hereof of notice of the commencement of any action, such
indemnified party will, if a claim in respect thereof is to be made against the
indemnifying party under either of such subsections, notify the indemnifying
party in writing of the commencement thereof. In case any such action is brought
against the indemnified party and it shall so notify the indemnifying party of
the commencement thereof, the indemnifying party shall be entitled to
participate in, and, to the extent that it so chooses, to assume the defense
thereof with counsel reasonably satisfactory to such indemnified party, and,
after notice from the indemnifying party that it so chooses, such indemnifying
party shall not be liable for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof, provided,
however, that if the indemnifying party fails to take reasonable steps necessary
to diligently defend such claim within


                                       11
<PAGE>

twenty (20) days after receiving notice from the indemnified party that the
indemnified party believes the indemnifying party has failed to take such steps,
the indemnified party may assume its own defense and the indemnifying party
shall be liable for any expenses therefor. The indemnity agreements in this
Section 10 shall be in addition to any liabilities which the indemnifying
parties may have pursuant to law.

      10.4 If the indemnification provided for in this Section 10 from the
indemnifying party is unavailable to an indemnified party hereunder in respect
of any losses, claims, damages, liabilities or expenses referred to herein, then
the indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or expenses in such proportion as
is appropriate to reflect the relative fault of the indemnifying party and
indemnified parties in connection with the actions which resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and
indemnified parties shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party or
indemnified parties, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid
or payable by a party as a result of the losses, claims, damages, liabilities
and expenses referred to above shall be deemed to include, subject to the
limitations set forth in Section 10 hereof, any legal or other fees or expenses
reasonably incurred by such party in connection with any investigation or
proceeding.

      The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 10 were determined by pro rata allocation
or by any other method of allocation which does not take into account the
equitable considerations referred to in the immediately preceding paragraph. No
Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

      Section 11. Sales under Rule 144. With a view to making available to each
Shareholder and Piggy-Back Shareholder the benefits of Rule 144 promulgated
under the Securities Act and any other similar rule or regulation of the
Commission that may at any time permit such Shareholder or Piggy-Back
Shareholder to sell the Registrable Securities without registration, Corporation
agrees to:

      (a) make and keep public information available, as those terms are
understood and defined in Rule 144 (or any successor provision);

      (b) file with the Commission in a timely manner all reports and other
documents required of Corporation under the Securities Act and the Exchange Act;


                                       12
<PAGE>

      (c) furnish to such Shareholder or Piggy-Back Shareholder forthwith upon
request (i) a written statement by Corporation that it has complied with the
reporting requirements of Rule 144 (or any successor provision), the Securities
Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly
report of Corporation and such other reports and documents so filed by
Corporation under the Securities Act and the Exchange Act and (iii) such other
information as may be reasonably requested by such Shareholder or Piggy-Back
Shareholder in availing itself of any rule or regulation of the Commission which
permits the selling of any such securities without registration; and

      (d) after any sale of Registrable Securities pursuant to Rule 144, to the
extent allowed by law, to cause any restrictive legends to be removed and any
transfer restrictions to be rescinded with respect to such Registration
Securities.

      Section 12. Removal of Legend. The Corporation agrees, to the extent
allowed by law, to remove any legends on certificates representing Registrable
Securities or Piggy-Back Registrable Securities describing transfer restrictions
applicable to such securities upon the sale of such securities (i) pursuant to
an effective Registration Statement under the Securities Act or (ii) in
accordance with the provisions of Rule 144 under the Securities Act.

      Section 13. Notices. Any notice to be given by any party hereunder to any
other shall be in writing, mailed by certified or registered mail, return
receipt requested, and shall be addressed to the other parties at the addresses
listed on the signature pages hereof. All such notices shall be deemed to be
given three (3) days after the date of mailing thereof.

      Section 14. Modification. Notwithstanding anything to the contrary in this
Agreement or otherwise, no modification, amendment or waiver of any of the
provisions of this Agreement shall be effective unless in writing and signed by
the Corporation and the Shareholders holding not less than 95% of the
Registrable Securities then outstanding.

      Section 15. Non-Waiver. The failure to enforce at any time any of the
provisions of this Agreement, or to require at any time performance by any other
party of any of the provisions hereof, shall in no way be construed to be a
waiver of such provisions.

      Section 16. Partial Invalidity. If any clause, sentence, paragraph,
section or part of this Agreement shall be deemed invalid, unenforceable or
against public policy, the part which is invalid, unenforceable or contrary to
public policy shall not affect, impair, invalidate or nullify the remainder of
this Agreement, but the invalidity, unenforceability or contrariness to public
policy shall be


                                       13
<PAGE>

confined only to the clause, sentence, paragraph, section or party of this
Agreement so invalidated, unenforceable or against public policy.

      Section 17. Construction. The language in all parts of this Agreement
shall in all cases be construed simply, according to its fair meaning, and shall
not be construed strictly for or against either of the parties hereto.

      Section 18. Governing Law. This Agreement shall be governed and construed
according to the laws of the State of Alabama, without regard to its conflicts
of law principles.

      Section 19. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall constitute an original and all of which
together shall constitute but one and the same instrument.

      Section 20. Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of and be enforceable by the parties hereto and their
respective successors and permitted assigns.

      Section 21. Specific Performance. The parties agree that, to the extent
permitted by law, (i) the obligations imposed on them in this Agreement are
special, unique and of an extraordinary character, and that in the event of a
breach of any such party damages would not be an adequate remedy and (ii) the
other party shall be entitled to specific performance and injunctive and
equitable relief in addition to any other remedy to which it may be entitled at
law or in equity.

written consent, as necessary or appropriate) and cause its Affiliates to vote

capital stock of the Company presently or at any future time owned by the
Shareholders) which it is entitled to vote (or control the voting directly or
indirectly) to ensure that the following shall occur:

or (v) enter into a relationship with a competitor of the Company; provided that
during the six-month period commencing upon the termination of the Employment
Period or the period in which the Employee is employed by the Company, whichever
is longer, nothing in this paragraph 7(e) shall prohibit Employee from entering
into contractual relations to obtain capital as long as the Board of Directors
of the Company in good faith determines that such relations are not detrimental
to the Company.

            (f) Employee acknowledges and agrees that the services to be
rendered by him are of a special, unique and extraordinary character and, in
connection with such services, he will have access to Business Opportunities,
Intellectual Property and Confidential Information vital to the Company's
businesses. By reason of this, the Employee consents and agrees that if he
violates any of the provisions of this Section 7, the Company would sustain
irreparable harm and, therefore, in addition to any other remedies which the
Company may have under this Agreement or otherwise, the Company shall be
entitled to an injunction restraining the Employee from committing or continuing
any such violation of this Agreement. Such right to an injunction shall be
cumulative and in addition to, and not in lieu of, any other remedies to which
the Company may show itself justly entitled. Further, during any period in which
the Employee is in breach of the covenants set forth in this Section 7, the time
period of this covenant shall be extended for an amount of time that the
Employee is in breach.

            (g) The Employee agrees to promptly deliver to the Company, upon
termination of Employee's employment with the Company, or at any other time when
the Company so requests, all documents relating to the business of the Company,
including, without limitation: all geological and geophysical reports and
related data such as maps, charts, logs, seismographs, seismic records and other
reports and related data, calculations, summaries, memoranda and opinions
relating to the foregoing, production records, electric logs, core data,
pressure data, lease files, well files and records, land files, abstracts, title
opinions, title or curative matters, contract files, notes, records, drawings,
manuals, correspondence, financial and accounting information, customer lists,
statistical data and compilations, patents, copyrights, trademarks, trade names,
inventions, formulae, methods, processes, agreements, contracts, manuals or any
other documents relating to the business of the Company (collectively, the
"Business Records"), and all copies thereof and therefrom. The Employee confirms
that all of the Business Records (and all copies thereof and therefrom) that are
required to be delivered to the Company pursuant to this paragraph 7(g)
constitute the exclusive property of the Company. The obligation of
confidentiality set forth in this Section 7 shall continue


                                       5
<PAGE>

notwithstanding the Employee's delivery of any such documents to the Company.
Notwithstanding the foregoing provisions of this Section 7 or any other
provision of this Agreement, the Employee shall be entitled to retain any
written materials which, as shown by the Employee's records, were in Employee's
possession on or prior to the date hereof, subject to the Company's right to
receive a copy of all such materials.

            (h) The representations and covenants contained in this Section 7 on
the part of the Employee will be construed as ancillary to and independent of
any other provision of this Agreement, and the existence of any claim or cause
of action of the Employee against the Company or any officer, director, or
shareholder of the Company, whether predicated on this Agreement or otherwise,
shall not constitute a defense to the enforcement by the Company of the
covenants of the Employee contained in this Section 7. In addition, the
provisions of this Section 7 shall continue to be binding upon the Employee in
accordance with their terms, notwithstanding the termination of the Employee's
employment hereunder for any reason.

            (i) The parties to this Agreement agree that the limitations
contained in this Section 7 with respect to time, geographical area, and scope
of activity are reasonable. However, if any court shall determine that the time,
geographical area, or scope of activity of any restriction contained in this
Section 7 is unenforceable, it is the intention of the parties that such
restrictive covenants set forth herein shall not thereby be terminated but shall
be deemed amended to the extent required to render it valid and enforceable.

      8. Termination By the Company For Cause.

            (a) The Company may terminate Employee's employment under this
Agreement for Cause. The termination shall be evidenced by written notice
thereof to the Employee and shall specify the Cause for termination. For
purposes hereof, the term "Cause" shall mean (i) the inability of Employee,
despite any reasonable accommodation required by law, due to bodily injury or
disease or any other physical or mental incapacity, to perform the services
provided for hereunder for a period of 120 days in the aggregate, within any
given period of 180 consecutive days during the term of this Agreement, in
addition to any statutorily required leave of absence, (ii) conduct of the
Employee that constitutes fraud, dishonesty, theft, or a criminal act involving
moral turpitude, in each case only if it materially affects his ability to
perform the duties and responsibilities of his position or has a material
adverse effect on the Company, (iii) commission of a material act of fraud
against the Company, (iv) embezzlement of funds or misappropriation of other
property by the Employee from the Company; or (v) failure of Employee to observe
or perform his material duties and obligations as an employee of the Company or
a material breach of this Agreement, after thirty (30) days advance written
notice of such failure or breach which has not been cured.

            (b) Upon Employee's death or if Employee's employment with the
Company is terminated for Cause, Employee shall be paid his salary through the
month of his death or termination.


                                       6
<PAGE>

      9. Termination By the Company Without Cause.

            (a) The Company may terminate Employee's employment under this
      Agreement without Cause. The termination shall be evidenced by written
      notice thereof to the Employee and shall specify that the termination was
      without Cause.

            (b) If Employee's employment with the Company is terminated without
      Cause during any period in which Employee is employed by the Company,
      Employee shall be entitled to receive, within ten (10) days of such
      termination, the amount of compensation Employee would have earned if his
      employment had continued through the remainder of the Employment Period.
      Notwithstanding the foregoing, if the payment referred to above is not
      made within ten (10) days of Employee's termination, all unpaid amounts
      shall bear interest at a rate equal to the New York Prime (as published in
      the Wall Street Journal) on the date of such termination.

      10. Burden and Benefit. This Agreement shall be binding upon, and shall
inure to the benefit of, the Company and Employee, and their respective heirs,
personal and legal representatives, successors and permitted assigns.

      11. Governing Law. It is understood and agreed that the construction and
interpretation of this Agreement shall at all times and in all respects be

Agreement in any suit, action, or proceeding of the nature specified above by

option or other agreement or understanding with respect to the sale, transfer,

      8. Non-Waiver. The failure to enforce at any time any of the provisions of
