conversion price of $5.875 per share, and c) if not already converted, an option

Preferred Stock shall be entitled to receive when, as and if declared by the
Board of Directors out of funds legally available for the purpose, cumulative
dividend payments, payable quarterly in accordance with this SECTION 3, on March
31, June 30, September 30 and December 31 of each year commencing on December
31, 1996.  Dividends on the 1996 Series A Preferred Stock shall be cumulative
from the date of original issue of the 1996 Series A Preferred Stock. 
Accumulations of dividends, whether or not declared, shall bear interest at a
rate of 8.75% per annum, compounded quarterly, which interest shall be deemed
accrued dividends payable in the same manner and at the same time as dividends
and redemptions shall be paid on the 1996 Series A Preferred Stock.

         3.2. FORM OF PAYMENT.  Dividends on the 1996 Series A Preferred Stock
shall be paid in cash at a quarterly rate of $.21875 per share; PROVIDED,
HOWEVER, that if any such dividend shall not be declared on or before the fifth
Business Day of the month after the quarterly payment date on which it accrues
or paid by the penultimate Business Day of such calendar month (the "DIVIDEND
PAYMENT DATE"), the holders shall have the option to require the Company to pay
such accumulated dividends in shares (the "DIVIDEND SHARES") (whether whole or
fractional) of Freely Tradeable Common Stock valued at the Cash Equivalent
Amount for the purposes of determining the number of shares (or fraction
thereof) of Freely Tradeable Common Stock to be issued, PROVIDED, FURTHER, that
with respect to the first time any such dividend is not both declared and paid
in cash on or before the Dividend Payment Date, the Company shall, within thirty
(30) days of the Dividend Payment Date, prepare and file with the Commission a
"shelf" registration statement (a "SHELF REGISTRATION") on any appropriate form
pursuant to Rule 415 under the Act (or similar rule that may be adopted by the
Commission) with respect to the Dividend Shares having a Cash Equivalent Amount
equal to the projected dividends over a one year period, and use best efforts to
cause such Shelf Registration to become and remain continuously effective until

sale of all 

                                     - 11 -
<PAGE>

Dividend Shares covered thereby; and prepare and file with the Commission 
such amendments and supplements to the Shelf Registration and the prospectus 
used in connection therewith as may be necessary to keep the Shelf 
Registration continuously effective and to comply with the provisions of the 
Act with respect to the transfer of all securities covered by the Shelf 
Registration whenever the holder or holders of the 1996 Series A Preferred 
Stock shall desire to sell or otherwise dispose of the same; PROVIDED, that 
no amendment to the Shelf Registration naming any holder of the 1996 Series A 
Preferred Stock as selling shareholders shall be filed with the Commission 
until such holder shall have had at least seven (7) days to review the Shelf 
Registration as originally filed and theretofore amended and to approve or 
disapprove any portion of the Shelf Registration describing or referring to 
such holder.   The Company shall file a new Shelf Registration, pursuant to 
the same procedures and subject to the same rights of the 1996 Series A 
Preferred Stock as set forth above with respect to the prior Shelf 
Registration, covering a like number (ie: having a Cash Equivalent Amount 
equal to the projected dividends over a one year period) of Dividend Shares 
at such time that the Cash Equivalent Amount (determined on the date of 
calculation) of the unissued Dividend Shares covered by the prior Shelf 
Registration filed under this SECTION 3.3 shall be less than an amount equal 
to one quarter (1/4) of the dividends projected to accrue on the outstanding 
1996 Series A Preferred Stock.  At any time from and after any holder of the 
1996 Series A Preferred Stock shall be entitled to exercise the option to 
require the Company to pay accumulated accrued dividends in Dividend Shares, 
any such holder may notify the Company of its intent to exercise its option 
to require the Company to pay accumulated dividends in shares of Freely 
Tradeable Common Stock no later than the fifteenth Business Day of any month 
and the Company shall issue the Freely Tradeable Common Stock to the holders 
of the 1996 Series A Preferred Stock within ten (10) Business Days after such 
notification by TCW.  Any holder receiving Dividend Shares shall submit to 
the Company no less frequently than once each calendar quarter written notice 
of the amount and date of receipt of any Net Cash Receipts as described in 
clause (ii) of the definition thereof received by such holder in the prior 
calendar quarter.

         3.3. RECORD DATE.  The Board of Directors shall fix a record date for
the determination of holders of the 1996 Series A Preferred Stock entitled to
receive payment of a dividend declared thereon, which record date shall be not
more than sixty (60) days prior to the date fixed for the payment thereof.

         3.4. RESTRICTED PAYMENTS.  Unless full cumulative dividends on the
1996 Series A Preferred Stock have been paid, no dividends shall be declared or
paid or set apart for payment or other distribution upon any Junior Stock nor
shall any Junior Stock be redeemed, purchased or otherwise acquired by the
Company for any consideration (or any payment made to or available for a sinking
fund for the redemption of any shares of such stock) by the Company except that
the Company shall be permitted to redeem, purchase or otherwise acquire any
existing outstanding shares of the 1993 Series A Preferred Stock and the
warrants described in ATTACHMENT 1 hereto provided that the aggregate
consideration paid by the Company in connection therewith shall not exceed
$100,000.

         4.   REDEMPTION.

         4.1. MANDATORY REDEMPTION.  In the event that the Company has not
received before June 30, 1997 at least $15,000,000 of net cash proceeds from the
issuance and sale by the Company of Common Stock which was not issued and
outstanding on the Closing Date, the Company shall redeem annually on each of
June 30, 2006, June 30, 2007 and June 30, 2008, 333,333 shares of the 1996
Series A Preferred Stock.  Redemptions pursuant to this SECTION 4.1 shall be
paid, at the option of the Company, (i) in cash for a price per share of 1996
Series A Preferred Stock equal to the Liquidation Amount, (ii) with shares
(whether whole or fractional) of Freely Tradeable Common Stock having a Cash
Equivalent Amount equal to the Liquidation Amount or (iii) by combination of
cash and such shares; PROVIDED, that if such redemption shall be paid in a
combination of cash and shares of Common Stock, all holders of the 1996 Series A
Preferred Stock shall receive cash and shares of Common Stock in the same ratio,
except that the Company, at its option, may pay cash in lieu of fractional
shares of Common Stock valued at the Cash Equivalent Amount.  In the event that
at any time less than all of the

                                     - 13 -


<PAGE>

shares of 1996 Series A Preferred Stock outstanding are to be redeemed 
pursuant to this SECTION 4.1, the Company shall effect such redemption pro 
rata according to the number of shares of 1996 Series A Preferred Stock held 
by each holder thereof.

         4.2. REDEMPTION UPON CHANGE OF CONTROL. Upon the sale, conveyance or 
disposition of all or substantially all of the assets of the Company, the net 
proceeds of which, after making provisions for all liabilities (contingent or 
otherwise) of the Company, exceed the amount required to pay the full 
Liquidation Amount to which each holder of the 1996 Series A Preferred Stock 
is entitled upon liquidation of the Company, or a sale, conveyance or 
disposition of a majority of the outstanding shares of Common Stock in a 
transaction or series of related transactions (except for a merger or 
consolidation after the consummation of which the stockholders of the Company 
own a majority of the voting securities of the surviving corporation or its 
parent corporation), each holder of the 1996 Series A Preferred Stock shall 
have the right to require that the Company redeem all or any part of such 
holder's 1996 Series A Preferred Stock for cash out of legally available 
funds at a price per share equal to the Liquidation Amount.

         If on the date of such sale, conveyance or disposition funds legally 
available for such redemption shall be insufficient to redeem all of the 
outstanding shares of 1996 Series A Preferred Stock held by holders who have 
elected to have their shares redeemed, funds to the extent legally available 
shall be used for such purpose and the Company shall effect such redemption 
pro rata according to the number of shares of 1996 Series A Preferred Stock 
held by each holder thereof.  The redemption requirements provided hereby 
shall be continuous, so that if on the date of such sale, conveyance or 
disposition such requirements can not be fully discharged, without further 
action by any holder of the 1996 Series A Preferred Stock funds legally 
available shall be applied therefor until such requirements are fulfilled.

         Upon payment in full of the amounts owing under this SECTION 4.2 to 
any holder of 1996 Series A Preferred Stock who has elected to have its 
shares redeemed, then notwithstanding


                                    - 14 -
<PAGE>

that the certificate or certificates evidencing such shares shall not have 
been surrendered, the dividends with respect to such shares shall cease to 
accrue after the date of such payment in full and all rights with respect to 
such shares shall forthwith terminate.

         4.3. OPTIONAL REDEMPTION. The shares of the 1996 Series A Preferred 
Stock may be redeemed, in whole but not in part, at the option of the 
Company, if (i) the Board of Directors of the Company has approved a bona 
fide merger, consolidation or acquisition opportunity of the Company which is 
evidenced by a duly executed letter of intent or agreement between all 
applicable parties and which would require the affirmative vote or consent of 
the holders of at least 70% of the outstanding shares of the 1996 Series A 
Preferred Stock pursuant to SECTION 6.5(b) below, (2) the Company has made a 
detailed presentation to the holders of the 1996 Series A Preferred Stock 
regarding the proposed merger or acquisition, and (3) within five (5) 
Business Days of such presentation such holders (A) do not provide their 
consent to such transaction or (B) do not convert the 1996 Series A Preferred 
Stock to Common Stock.

         Redemption pursuant to this SECTION 4.3 shall be paid, in 
immediately available funds for a price per share of 1996 Series A Preferred 
Stock equal to $21.50.

         4.4. REDEMPTION NOTICE. The Company shall give written notice (the 
"REDEMPTION NOTICE") to each holder of the 1996 Series A Preferred Stock at 
least 20 Business Days prior to the date (the "REDEMPTION DATE") of any 
redemption required or permitted under this SECTION 4, such notice to be 
addressed to each holder at the address as it appears on the stock transfer 
books of the Company.  Such notice shall specify (i) the Redemption Date, 
(ii) the number of all shares of the 1996 Series A Preferred Stock of each 
holder to be redeemed and (iii) the amount and form or forms of payment 
therefor and the method of calculation thereof (the "REDEMPTION AMOUNT").  On 
or after each such Redemption Date, each holder of the 1996 Series A 
Preferred Stock shall surrender a certificate or certificates representing 
the number of shares of the 1996 Series A Preferred Stock to be redeemed as 
stated in the Redemption Notice provided by the


                                    - 15 -
<PAGE>

Company.  If the Redemption Notice shall have been duly given, and if on the 
Redemption Date the Redemption Amount is either paid or made reasonably 
available for payment in immediately available funds, Freely Tradeable Common 
Stock or a combination thereof as provided herein to the holders of the 1996 
Series A Preferred Stock being redeemed, then notwithstanding that the 
certificates evidencing any of the 1996 Series A Preferred Stock so called 
for redemption shall not have been surrendered, the dividends with respect to 
such shares shall cease to accrue after the Redemption Date and all rights 
with respect to such shares shall forthwith terminate after the Redemption 
Date, except only the right of the holders to receive the Redemption Amount 
without interest upon surrender of their certificate or certificates.  
Notwithstanding anything to the contrary contained herein, with respect to 
any shares of 1996 Series A Preferred Stock scheduled for redemption pursuant 
to a Redemption Notice, the holders of such shares may at any time prior to 
the Redemption Date, upon written notice to the Company as provided herein, 
exercise their right to convert all or any portion of such shares into Common 
Stock at the Conversion Price.

         5.   LIQUIDATION RIGHTS.

         Upon any liquidation, dissolution or winding up of the affairs of 
the Company, no distribution shall be made to the holders of any Junior Stock 
unless, prior to the first such distribution, the holders of the 1996 Series 
A Preferred Stock shall have received the Liquidation Amount.  If the assets 
distributable in any such event to the holders of the 1996 Series A Preferred 
Stock are insufficient to permit the payment to such holders of the full 
preferential amounts to which they may be entitled, such assets shall be 
distributed ratably among the holders of the 1996 Series A Preferred Stock in 
proportion to the full preferential amount each such holder would otherwise 
be entitled to receive.  

         6.   VOTING RIGHTS OF 1996 SERIES A PREFERRED STOCK.

         6.1. VOTING RIGHTS.  The holders of the 1996 Series A Preferred

<PAGE>

to law or otherwise, to a number of votes per share of the 1996 Series A 
Preferred Stock equal to the number of shares of Common Stock issuable upon 
conversion of one share of the 1996 Series A Preferred Stock on the date of 
such vote, and on all such matters shall vote together as one class with the 
holders of Common Stock and the holders of all other shares of stock entitled 
to vote with the holders of Common Stock on such matters.  Notwithstanding 
the foregoing, the holders of the 1996 Series A Preferred Stock shall at all 
times have the right, as a class, to elect at least one member of the Board 
of Directors of the Company; PROVIDED, that in the event that the holders of 
the 1996 Series A Preferred Stock do not exercise their right to elect a 
board member, they may appoint an observer who may attend and participate in 
all meetings (including committee meetings) of the Board of Directors of the 
Company and who shall be entitled to the same expense reimbursement as 
Directors of the Company.

         6.2. SPECIAL VOTING RIGHTS. In addition to the voting rights 
described in SECTION 6.1 above, the holders of the 1996 Series A Preferred 
Stock shall have the voting powers provided for by law and the further voting

Voting Events (as defined below) occurs and remains outstanding and has not 
been specifically waived in writing by holders of 70% or more of the shares 
of the 1996 Series A Preferred Stock, then, to the extent permitted by law as 
relating to directorships, the holders of such 1996 Series A Preferred Stock 
shall have the right, voting separately from all other classes and series, to 
call a special meeting of all Shareholders and to elect a total of 75% of the 
directors of the Company.  The remaining directors shall be elected by the 
other classes or series of stock entitled to vote therefor.  If and when such 
right of the holders of the 1996 Series A Preferred Stock becomes operative, 
the maximum authorized number of members of the Board of Directors of the 
Company shall automatically be increased to the extent necessary to create 
any vacancy or vacancies to be filled only by vote of the holders of the 1996 
Series A Preferred Stock then outstanding as hereinafter set forth.  Whenever 
such right of the holders of the 1996 Series A Preferred Stock shall become 
operative, such right shall be


                                    - 17 -
<PAGE>

exercised initially either at a special meeting of the holders of the 1996 
Series A Preferred Stock called as provided in SECTION 6.3 below or at any 
annual meeting of stockholders held for the purpose of electing directors, 
and thereafter at such annual meetings.  In electing the directors to be 
elected by the holders of the 1996 Series A Preferred Stock, each holder of 
such stock shall have one vote for each share thereof held.  The right of the 
holders of the 1996 Series A Preferred Stock, voting separately from all 
other classes and series, to elect 75% of the members of the Board of 
Directors of the Company as aforesaid shall continue until such Special 
Voting Event is cured or waived as set forth above, at which time the right 
of the holders of the 1996 Series A Preferred Stock to vote separately and as 
a class as provided in this SECTION 6.2.1 shall terminate (subject to 
becoming operative again in the event of a subsequent Special Voting Event) 
and the maximum authorized number of members of the Board of Directors of the 
Company shall automatically be reduced if such number was increased at the 
time when the terminated voting right of the holders of the 1996 Series A 
Preferred Stock became operative.  Notwithstanding the foregoing, in no event 
shall the Company increase the number of members of the Board of Directors 
above nine, plus those members of the Board of Directors elected by the 
holders of the 1996 Series A Preferred Stock.

         Such "SPECIAL VOTING EVENTS" are:

    Preferred Stock when such redemption is required hereunder;

              (b) the occurrence of any event or condition in respect of any

    trustee to cause (whether or not such holder or trustee elects to cause)
    such debt or security, or a portion thereof, to become due prior to its
    stated maturity or prior to its regularly scheduled dates of payment
    PROVIDED, that, with respect to any debt other than the Company's senior
    bank or


                                    - 18 -
<PAGE>

    other credit facility, such debt exceeds $3,000,000; and the Company is
    given notice of the acceleration of such debt or other security;

              (c) the commencement of an involuntary case or other proceeding
    against the Company or any of its subsidiaries, which seeks liquidation,
    reorganization or other relief with respect to it or its debtor, other
    liabilities under any bankruptcy, insolvency or other similar law now or
    hereafter in effect or seeking the appointment of a trustee, receiver,
    liquidator, custodian or other similar official of it or any substantial
    part of its property, or the entry of an order for relief against the
    Company or any of its subsidiaries in any such case under the United States
    Bankruptcy Code;

              (d) the commencement by the Company or any of its subsidiaries of

    any of its subsidiaries of the commencement of a voluntary case or other
    proceeding, seeking liquidation, reorganization or other relief with
    respect to itself or its debts or other liabilities under any bankruptcy,
    insolvency or other similar law now or hereafter in effect or seeking the
    appointment of a trustee, receiver, liquidator, custodian or other similar
    official of it or any substantial part of its property, or consent to any
    such relief or to the appointment of or taking possession by any such
    official in an involuntary case or other proceeding commenced against it,
    or the making by the Company or any of its subsidiaries of a general
    assignment for the benefit of creditors, or failure by the Company or any
    of its subsidiaries generally to or written admission of its inability to

    at least 60 days after delivery of written notice thereof to the Company; 

         In the event at any time after January 1, 1999 that the average 
closing price of the Company's Common Stock (as adjusted for stock dividends, 
split-ups, mergers, recapitalizations, combinations, exchanges of shares or 
the like) on the securities exchange or other national market system on which 
the Common Stock is then listed over a period of at least 60 continuous 
trading days commencing after December 31, 1998 shall be in excess of 120% of 
the Required Forced Conversion Market Price described in SECTION 8.3 below in 
effect on each of such trading days, the Special Voting Events set forth

the right, voting separately from all other classes and series, to elect one 
additional director of the Company every 60 days until such time as the 
Limited Voting Event no longer remains outstanding, PROVIDED, HOWEVER, that 
if the Board of Directors shall increase above seven (7) persons, excluding 
those directors appointed by the holders of the 1996 Series A Preferred 
Stock, the holders of the 1996 Series A Preferred Stock shall have the right, 
voting separately from all other classes and series, to elect one additional 
director of the Company every 45 days until such time as the Limited Voting 
Event no longer remains outstanding.  The remaining directors shall be

<PAGE>

other classes or series of stock entitled to vote therefor, including the 
1996 Series A Preferred Stock as set forth in SECTION 6.1.  If and when such 
right of the holders of the 1996 Series A Preferred Stock becomes operative, 
the maximum authorized number of members of the Board of Directors of the 
Company shall automatically be increased to the extent necessary to create 
any vacancy or vacancies to be filled only by vote of the holders of the 1996 
Series A Preferred Stock then outstanding as hereinafter set forth.  Whenever 
such right of the holders of the 1996 Series A Preferred Stock shall become 
operative, such right shall be exercised initially either at a special 
meeting of the holders of the 1996 Series A Preferred Stock called as 
provided in SECTION 6.3 below or at any annual meeting of stockholders held 
for the purpose of electing directors, and thereafter at such annual 
meetings.  In electing the directors to be elected by the holders of the 1996 
Series A Preferred Stock pursuant to this SECTION 6.2.2, each holder of such 
stock shall have one vote for each share thereof held.  The right of the 
holders of the 1996 Series A Preferred Stock, voting separately from all 
other classes and series, to elect the members of the Board of Directors of 
the Company as aforesaid shall continue to accrue and increase until such 
Limited Voting Event is cured or waived as set forth above, at which time the 
right of the holders of the 1996 Series A Preferred Stock to vote separately 
and as a class as provided in this SECTION 6.2.2 shall terminate (subject to 
becoming operative again in the event of a subsequent Limited Voting Event) 
and the maximum authorized number of members of the Board of Directors of the 
Company shall automatically be reduced if such number was increased at the 
time when the terminated voting right of the holders of the 1996 Series A 
Preferred Stock became operative.  Notwithstanding the foregoing, in no event 
shall the Company increase the number of members of the Board of Directors 
above nine, plus those members of the Board of Directors elected by the 
holders of the 1996 Series A Preferred Stock.

         Such "LIMITED VOTING EVENTS" are:

         (a)  the occurrence of a Coverage Deficiency; 


                                    - 21 -
<PAGE>

         (b)  a breach by the Company of any material covenant, term or 
condition in respect of any debt of the Company in excess of $2,000,000 which 
breach is continuing and uncured; 

         (c)  the occurrence of a failure to perform on a timely basis any 
material component of the Development Plan; or

         (d)  the failure of the Company to cause all shares of the 1993 
Series A Preferred Stock to be redeemed or cancelled on or before July 1, 
1997.

         6.3. PROCEDURES RELATING TO SPECIAL VOTING RIGHTS.

              (a) At any time when the special voting rights of the holders of
    the 1996 Series A Preferred Stock provided in SECTION 6.2 above shall have
    become operative and not have been exercised, a proper officer of the
    Company shall, upon the written request of the holders of record of at
    least 20% of the shares of 1996 Series A Preferred Stock then outstanding
    addressed to the Secretary of the Company, call a special meeting of the
    holders of the 1996 Series A Preferred Stock for the purpose of electing
    the allotted directors to be elected by the 1996 Series A Preferred Stock. 
    Such meeting shall be held at the earliest practicable date upon the notice
    required for annual meetings of stockholders at such place in the
    continental United States as may be specified in such written request.  If
    such meeting shall not be called by the proper officer of the Company
    within twenty (20) days after the personal service of such written request
    upon the Secretary of the Company, or within twenty (20) days after mailing
    the same within the United States by registered or certified mail enclosed
    in a postpaid envelope addressed to the Secretary of the Company at its
    principal office, then the holders of record of at least 20% of the shares
    of 1996 Series A Preferred Stock then outstanding may designate in writing
    one of their number to call such meeting at the expense of the Company, and
    such meeting may be called by the person so designated upon the notice
    required for annual meetings of stockholders and shall be held at such
    place in the continental United States as may be specified in such


                                    - 22 -
<PAGE>

    notice. Notwithstanding the provisions of this SECTION 6.3, no such special
    meeting shall be called during the period of sixty (60) days immediately
    preceding the date fixed for any annual or special meeting of stockholders
    if the staff of the Securities and Exchange Commission shall have advised
    the Company that the calling of any such meeting shall require the Company
    to amend or supplement its proxy soliciting materials relating to such
    annual or special meeting of stockholders; and no such special meeting
    shall be called if in connection with such meeting a proxy solicitation
    conforming to the rules and regulations issued under the Securities 
    Exchange Act of 1934, as amended, shall be required, but in such event the
    election of directors by the holders of the 1996 Series A Preferred Stock
    shall take place at the next annual meeting of stockholders, unless the
    right of the holders of the 1996 Series A Preferred Stock to elect
    directors shall in the meantime have terminated.

              (b) Upon any termination of the right of the holders of the 1996
    Series A Preferred Stock to elect directors as hereinabove provided, the
    term of office of any director then in office elected by the 1996 Series A
    Preferred Stock shall terminate immediately.  If the office of any director
    elected by the holders of the 1996 Series A Preferred Stock becomes vacant
    by reason of death, resignation, retirement, disqualification, removal from
    office or otherwise, then the procedure provided for in SECTION 6.3(a)
    above shall be used to fill the vacancy.

              (c) Subject to the provisions of SECTION 6.2, the By-Laws of the
    Company shall automatically be deemed amended from time to time to provide
    for the increase or reduction in the maximum authorized number of members
    of the Board of Directors and for the election procedure as hereinabove in
    this SECTION 6.3 provided.

         6.4. RIGHTS RELATING TO BOARD OF DIRECTORS.

              The Company will promptly execute and deliver to any individual
    elected to the Board of Directors, pursuant to SECTION 6.2, an agreement by
    the Company to indemnify and


                                    - 23 -
<PAGE>

    hold harmless such individual for any and all actions taken by such
    individual in his capacity as a member of the Board of Directors to the
    fullest extent permitted by the laws of the state of incorporation of the
    Company.  Unless waived or modified by the holders of a majority of the
    1996 Series A Preferred Stock, the Company will also use its best efforts
    to promptly provide for such individual such amount of director's liability
    insurance as is normal and customary for corporations which have common
    stock that is publicly traded on the American Stock Exchange.

1996 Series A Preferred Stock are outstanding, the Company will not, without 
the affirmative vote or consent of all of the holders of the outstanding 
shares of 1996 Series A Preferred Stock, voting as a separate class, amend or

Stock are outstanding, the Company will not, without the affirmative vote or 
consent of the holders of at least seventy percent (70%) of the outstanding 
shares of 1996 Series A Preferred Stock, voting as a separate class:

              (a) amend or repeal any provision of, or add any provision to,

              (e) declare or pay any dividend, or make any distribution, or
    purchase, redeem or otherwise acquire for value any capital stock or other

    prior to and after such distributions, and (ii) all accumulated dividends
    with respect to the 1996 Series A Preferred Stock have been paid in full
    immediately prior to such distribution; or

              (f) amend or otherwise modify in any material respect the
    Company's Development Plan.


         Subsection (b) of this SECTION 6.5 shall be of no further force or 
effect at such time that the total number of the Conversion Shares issuable 
upon conversion of all outstanding shares of the 1996 Series A Preferred 
Stock at the Conversion Price in effect from time to time, is equal to or 
less than five percent (5%) of the Company's total issued and outstanding

         8.   CONVERSION.  The 1996 Series A Preferred Stock shall be
convertible as follows:

         8.1. RIGHT OF HOLDER TO CONVERT.  Each share of the 1996 Series A
Preferred Stock shall be convertible, without the payment of any additional
consideration by the holder thereof and at the option of the holder thereof, at
any time after December 31, 1996, in whole or in part, at the office of the
Company or any transfer agent for the 1996 Series A Preferred Stock, into the
whole number of fully paid and nonassessable shares of Common Stock determined
by dividing the Liquidation Value by the Conversion Price in effect at the time
of conversion, plus, in lieu of any fractional share to which such holder would
otherwise be entitled, cash equal to such fraction multiplied by the Conversion
Price.

         8.2. MECHANICS OF CONVERSION BY HOLDER.  In order for any holder of
the 1996 Series A Preferred Stock to convert the same into Common Stock, he
shall surrender to the Company at the office of the Company or of any transfer
agent for the 1996 Series A Preferred Stock, the certificate or certificates
representing such 1996 Series A Preferred Stock, accompanied by written notice
to the Company that he elects to convert all or a specified number of such
shares and stating therein his name or the name or names of his nominees in
which he wishes the certificate or certificates for Common Stock to be issued. 
The Company shall, as soon as practicable thereafter, issue and deliver at such
office to such holder of the 1996 Series A Preferred Stock, or to his nominee or
nominees, a certificate or certificates representing the number of shares of
Common Stock to which he shall be entitled as aforesaid and, if less than the
full number of shares of the 1996 Series A Preferred Stock evidenced by such
surrendered certificate or certificates are being converted, a new certificate
or certificates, of like tenor, for the number of shares of the 1996 Series A
Preferred Stock evidenced by such surrendered certificate less the number of
such shares being converted.  Any conversion made at the election of a holder of
the 1996 Series A Preferred Stock shall be deemed to have been made immediately
prior to the close of business on the date of such surrender of the 1996 Series
A Preferred Stock to be converted, and the person or persons 

                                     - 30 -
<PAGE>

entitled to receive the Common Stock issuable upon conversion shall be 
treated for all purposes as the record holder or holders of such Common Stock 
on such date.

         8.3. RIGHT OF THE COMPANY TO CONVERT.  The shares of 1996 Series A
Preferred Stock may be converted, in whole but not in part, at the option of the
Company, into Freely Tradeable Common Stock at any time after December 31, 1998
if (i) there shall not have occurred within the six months prior to the date of
delivery of the Conversion Notice described in SECTION 8.4 below or be
outstanding on the date of conversion any event or condition that would give
rise to or constitute a Voting Event and (ii) the Common Stock of the Company
has traded on a recognized securities exchange or national market system more
than an average of 50,000 shares per day (as adjusted for stock dividends,
split-ups, mergers, recapitalizations, combinations, exchanges of shares or the
like) over the 20-trading day period prior to the date of the Conversion Notice
at an average closing price (the "REQUIRED FORCED CONVERSION MARKET PRICE")
equal to or greater than the difference of 






                                     - 31 -
<PAGE>

    (a)  the following percentage of the Conversion Price per share then in
    effect (i.e., as adjusted for stock dividends, split-ups, mergers,
    recapitalizations, combinations, exchanges of shares or the like but
    without adjustment as provided in either SECTION 8.5 or SECTION 8.6 or
    SECTION 8.7 below):

    Date of                             Percentage of
    Calculation:                        Conversion Price:
    ------------                        -----------------

    On or after December 31, 1998
     but prior to March 31, 1999              170%

    On or after March 31, 1999
     but prior to June 30, 1999               181.25%

    On or after June 30, 1999
     but prior to September 30, 1999          192.50%

    On or after September 30, 1999
     but prior to December 31, 1999           203.75%

    On or after December 31, 1999             215%

minus

    (b)  the NPV30 Amount per share of 1996 Series A Preferred Stock actually
    received by the holders of outstanding shares of 1996 Series A Preferred
    Stock with respect to such shares

PROVIDED, HOWEVER, that with respect to any calculation of Required Forced
Conversion Market Price on or after January 1, 2000, the NPV30 Amount to be
deducted pursuant to clause (b) shall be deemed to be zero (0).  Such conversion
shall be without the payment of any additional consideration by the holder and
shall be into the whole number of fully paid and nonassessable shares of Freely
Tradeable Common Stock determined by dividing (i) the aggregate Liquidation
Value relating to all outstanding shares of the 1996 Series A Preferred Stock by
(ii) the Conversion Price in effect at the time of conversion, plus, in lieu of
any fractional share to which such holder would otherwise 

                                     - 32 -
<PAGE>

be entitled, cash equal to such fraction multiplied by the Conversion Price.

         8.4. MECHANICS OF CONVERSION BY THE COMPANY.  In order for the Company
to convert the 1996 Series A Preferred Stock into Freely Tradeable Common Stock
pursuant to SECTION 8.3 above, the Company shall deliver written notice to the
holders of the 1996 Series A Preferred Stock that it elects to convert all of
such shares (the "CONVERSION NOTICE").  Such Conversion Notice shall set forth
the effective date of such conversion (the "CONVERSION DATE") which shall be not
less than five (5) Business Days after the date the Conversion Notice is
delivered to the holders of the 1996 Series A Preferred Stock and the Company's
calculation of the number of shares of Freely Tradeable Common Stock to be
issued to the holders of the 1996 Series A Preferred Stock upon such conversion
including without limitation the component calculations of the Liquidation Value
NPV30 and Net Cash Receipts.  Such calculations by the Company shall not be
binding upon the holders of the 1996 Series A Preferred Stock and if the holders
of the 1996 Series A Preferred Stock shall dispute the accuracy of such
calculations the holders shall not be obligated to surrender the certificate or
certificates representing the 1996 Series A Preferred Stock to be converted as
provided in the immediately following sentence and the conversion of the 1996
Series A Preferred Stock shall not be effective until such dispute is resolved
pursuant to the arbitration procedure described in Section 6.9 of the Stock
Purchase Agreement and the Conversion Date shall be automatically extended to
the date such dispute shall be resolved.  Prior to the Conversion Date, the
holders of the 1996 Series A Preferred Stock shall continue to have all rights
and benefits with respect thereto as set forth herein.  Upon the Conversion
Date, the holders shall surrender to the Company at the office of the Company or
of any transfer agent for the 1996 Series A Preferred Stock, the certificate or
certificates representing the 1996 Series A Preferred Stock to be converted. 
The Company shall, as soon as practicable thereafter, issue and deliver at such
office to such holders of the 1996 Series A Preferred Stock, or to their nominee
or nominees, certificates representing the number of shares of Freely Tradeable
Common Stock to which they shall be entitled as aforesaid.  Any conversion made
at the election of the Company 

                                     - 33 -
<PAGE>

pursuant to SECTION 8.3 above shall be deemed to have been made immediately 
prior to the close of business on the second Business Day after the date the 
Conversion Notice has been received by the holder of the 1996 Series A 
Preferred Stock, and the person or persons entitled to receive the Common 
Stock issuable upon conversion shall be treated for all purposes as the 
record holder or holders of such Common Stock on such date.

         8.5. ADJUSTMENTS TO CONVERSION PRICE FOR VOTING EVENTS.  In the event
that a Voting Event shall occur and is occurring the Conversion Price in effect
shall be adjusted to that number determined by multiplying the Conversion Price
then in effect by 80%.

         8.6. ADJUSTMENT TO CONVERSION PRICE ON JUNE 30, 1997.  In the event
that the Company has not received on or before June 30, 1997 at least
$15,000,000 of net cash proceeds from the issuance and sale by the Company of
Common Stock which was not issued and outstanding on the Closing Date, the
Conversion Price in effect on June 30, 1997 shall be reduced to the lower of (i)
$4.875 (as reduced or increased, for stock dividends, split-ups, mergers,
recapitalizations, combinations, exchanges of shares or the like) or (ii) 25%
above the lower of, as calculated on June 30, 1997, (A) the 10-Day Average Price
or (B) the 60-Day Average Price.

         8.7. ADJUSTMENT TO CONVERSION PRICE ON JULY 1, 1997.  In the event
that the mean average price per share (the "7/1/97 AVERAGE PRICE") received by
the Company upon the issuance of Common Stock in connection with the public
offerings described in clause (iv) of the definition of "Additional Shares of
Nonpreferred Stock" shall be less than the amount set forth in the column
entitled "7/1/97 Average Price" below, then the Conversion Price in effect on
July 1, 1997 shall be reduced (but not increased) to an amount equal to the
product of the percentage set forth in the column entitled "Applicable
Percentage" below opposite the applicable 7/1/97 Average Price multiplied by the
7/1/97 Average Price.


    7/1/97 AVERAGE PRICE:         APPLICABLE PERCENTAGE:

         8.8. ADJUSTMENTS TO CONVERSION PRICE FOR DILUTING ISSUES:

              (a) Stock Dividends, Subdivisions and Combinations.  In case at
    any time or from time to time the Company shall:

                   (1) take a record of the holders of its Nonpreferred Stock
         for the purpose of entitling them to receive a dividend payable in, or
         other distribution of, Nonpreferred Stock; 

                   (2) subdivide its outstanding shares of Nonpreferred Stock
         into a larger number of shares of Nonpreferred Stock; or

                   (3) combine its outstanding shares of Nonpreferred Stock
         into a smaller number of shares of Nonpreferred Stock;

    then the Conversion Price in effect immediately after the happening of any
    such event shall be proportionately decreased, in case of the happening of
    events described in subparagraphs (1) or (2) above, or proportionately
    increased, in case of the happening of events described in subparagraph (3)
    above.

              (b) Certain Other Dividends and Distributions.  In case at any
    time or from time to time the Company shall take a record of the holders of
    its Nonpreferred Stock for the purpose of entitling them to receive any
    dividend or other distribution of:

                                     - 35 -
<PAGE>

                   (1) cash (other than a cash distribution made as a dividend
         and payable out of earnings or earned surplus legally available for
         the payment of dividends under the laws of the jurisdiction of
         incorporation of the Company, to the extent, but only to the extent,
         that the aggregate of all such dividends paid or declared after the
         date hereof, does not exceed the consolidated net income, net of
         consolidated net losses, of the Company and its consolidated
         subsidiaries earned subsequent to the date hereof determined in
         accordance with generally accepted accounting principles);

                   (2) any evidence of its indebtedness (other than Convertible
         Securities), any shares of its stock (other than Additional Shares of
         Nonpreferred Stock) or any other securities or property of any nature
         whatsoever (other than cash and other than Convertible Securities or
         Additional Shares of Nonpreferred Stock); or 

                   (3) any warrants or other rights to subscribe for or
         purchase any evidences of its indebtedness (other than Convertible
         Securities), any shares of its stock (other than Additional Shares of
         Nonpreferred Stock) or any other securities or property of any nature
         whatsoever (other than cash and other than Convertible Securities or
         Additional Shares of Nonpreferred Stock);

    then the Conversion Price in effect shall be adjusted to that number
    determined by multiplying the Conversion Price then in effect by a fraction
    (x) the numerator of which shall be the Fair Market Price per share of
    Common Stock immediately prior to the date of taking such record minus the
    portion applicable to one share of Common Stock of any such cash so
    distributable and of the fair value of any and all such evidences of
    indebtedness, shares of stock, other securities or property, or warrants or
    other subscription or purchase rights, so distributable and (y) the
    denominator of which shall be the Fair Market Price per share of Common
    Stock immediately prior to the date of taking such record. 

                                     - 36 -

    Such fair value shall be determined pursuant to the Valuation 
    Procedure.  The "Valuation Procedure" is a determination of fair value 
    of any property made in good faith by the Board of Directors; PROVIDED, 
    that if the holders of a majority of the 1996 Series A Preferred Stock 
    object to such determination within 10 days of receipt of written 
    notification thereof, then the fair value of such property shall be 
    determined in good faith by a recognized national investment bank 
    selected by unanimous vote or consent of the Board of Directors, which 
    investment bank is not reasonably objected to by the holders of a 
    majority of the 1996 Series A Preferred Stock.  The fees and expenses 
    of such investment bank shall be paid by the Company.  A 
    reclassification of the Nonpreferred Stock into shares of Nonpreferred 
    Stock and shares of any other class of stock shall be deemed a 
    distribution by the Company to the holders of its Nonpreferred Stock of 
    such shares of such other class of stock within the meaning of this 
    SECTION 8.3(b) and, if the outstanding shares of Nonpreferred Stock 
    shall be changed into a larger or smaller number of shares of 
    Nonpreferred Stock as a part of such reclassification, shall be deemed 
    a subdivision or combination, as the case may be, of the outstanding 
    shares of Nonpreferred Stock within the meaning of SECTION 8.3(a).  

              (c) Issuance of Additional Shares of Nonpreferred Stock.  In case
    at any time or from time to time after the Closing Date, the Company shall
    (except as hereinafter provided) issue, whether in connection with the
    merger of a corporation into the Company or otherwise, any Additional
    Shares of Nonpreferred Stock for a consideration per share less than either
    the Conversion Price or the Fair Market Price per share of Common Stock on
    the Computation Date (determined as set forth in the last sentence of this
    SECTION 8.3(c)), then the Conversion Price shall be adjusted to the lower
    of either:

                   (i)  that number determined by multiplying the Conversion
         Price in effect immediately prior to such adjustment by a fraction (x)
         the numerator of which shall be the number of shares of Nonpreferred

                                      - 37 -
<PAGE>

         Stock, plus the number of shares of Nonpreferred Stock which the
         aggregate consideration for the total number of such Additional Shares
         of Nonpreferred Stock so issued would purchase at the Fair Market
         Price per share of Common Stock and (y) the denominator of which shall
         be the number of shares of Nonpreferred Stock plus the number of such
         Additional Shares of Nonpreferred Stock so issued; or 

                   (ii)  the value of the consideration per share for which
         such Additional Shares of Nonpreferred Stock were issued (or, in the
         case of adjustments under SECTIONS 8.3(d) or 8.3(e), are issuable).

    No adjustment of the Conversion Price shall be made under this SECTION
    8.3(c) upon the issuance of any Additional Shares of Nonpreferred Stock
    which are issued pursuant to the exercise of any warrants or other
    subscription or purchase rights or pursuant to the exercise of any
    conversion or exchange rights in any Convertible Securities, if any such
    adjustment shall previously have been made upon the issuance of such
    warrants or other rights or upon the issuance of such Convertible
    Securities (or upon the issuance of any warrant or other rights therefor)
    pursuant to SECTION 8.3(d) or 8.3(e).  For purposes of this SECTION 8.3(c),
    the Computation Date shall be the earlier of (i) the date on which the
    Company shall enter into a firm contract for the issuance of such
    Additional Shares of Nonpreferred Stock, or (ii) the date of actual
    issuance of such Additional Shares of Nonpreferred Stock.

              (d) Issuance of Warrants, Options or Other Rights.  In case at
    any time or from time to time after the Closing Date, the Company shall
    take a record of the holders of its Nonpreferred Stock for the purpose of
    entitling them to receive a distribution of, or shall otherwise issue, any
    warrants, options or other rights to subscribe for or purchase any
    Additional Shares of Nonpreferred Stock or any Convertible Securities and
    the consideration per share for which Additional Shares of Nonpreferred
    Stock may at any time thereafter be issuable pursuant to such warrants,

                                     - 38 -
<PAGE>

    options or other rights or pursuant to the terms of such Convertible
    Securities shall be less than either the Conversion Price or the Fair
    Market Price per share of Common Stock on the Computation Date (determined
    as set forth in the last sentence of this SECTION 8.3(d)), then the
    Conversion Price shall be adjusted as provided in SECTION 8.3(c).  Such
    adjustment shall be made on the basis that (i) the maximum number of
    Additional Shares of Nonpreferred Stock issuable pursuant to all such
    warrants, options or other rights or necessary to effect the conversion or
    exchange of all such Convertible Securities shall be deemed to have been
    issued as of the Computation Date (determined as set forth in the last
    sentence of this SECTION 8.3(d)), and (ii) the aggregate consideration for
    such maximum number of Additional Shares of Nonpreferred Stock shall be
    deemed to be the minimum consideration received and receivable by the
    Company for the issuance of such Additional Shares of Nonpreferred Stock
    pursuant to such warrants, options or other rights or pursuant to the terms
    of such Convertible Securities.  For purposes of this SECTION 8.3(d), the
    Computation Date shall be the earliest to occur of (a) the date on which
    the Company shall take a record of the holders of its Nonpreferred Stock
    for the purpose of entitling them to receive any such warrants, options or
    other rights, (b) the date on which the Company shall enter into a firm
    contract for the issuance of such warrants, options or other rights, and
    (c) the date of actual issuance of such warrants, options or other rights.

              (e) Issuance of Convertible Securities.  In case at any time or
    from time to time after the Closing Date, the Company shall take a record
    of the holders of its Nonpreferred Stock for the purpose of entitling them
    to receive a distribution of, or shall otherwise issue, any Convertible
    Securities and the consideration per share for which Additional Shares of
    Nonpreferred Stock may at any time thereafter be issuable pursuant to the
    terms of such Convertible Securities shall be less than either the
    Conversion Price or the Fair Market Price per share of Common Stock on the
    Computation Date (determined as set forth in the last sentence of this
    SECTION 8.3(e)), then the 

                                      - 39 -
<PAGE>

    Conversion Price shall be adjusted as provided in SECTION 8.3(c).  
    Such adjustments shall be made on the basis that (i) the maximum 
    number of Additional Shares of Nonpreferred Stock necessary to
    effect the conversion or exchange of all such Convertible Securities shall
    be deemed to have been issued as of the Computation Date (determined as set
    forth in the penultimate sentence of this SECTION 8.3(e)), and (ii) the
    aggregate consideration for such maximum number of Additional Shares of
    Nonpreferred Stock shall be deemed to be the minimum consideration received
    and receivable by the Company for the issuance of such Additional Shares of
    Nonpreferred Stock pursuant to the terms of such Convertible Securities. 
    No adjustment of the Conversion Price shall be made under this SECTION
    8.3(e) upon the issuance of any Convertible Securities which are issued
    pursuant to the exercise of any warrants or other subscription or purchase
    rights therefor, if any such adjustment shall previously have been made
    upon the issuance of such warrants or other rights pursuant to SECTION
    8.3(d).  For purposes of this Subsection, the Computation Date shall be the
    earliest of (a) the date on which the Company shall take a record of the
    holders of its Nonpreferred Stock for the purpose of entitling them to
    receive any such Convertible Securities, (b) the date on which the Company
    shall enter into a firm contract for the issuance of such Convertible
    Securities, and (c) the date of actual issuance of such Convertible
    Securities.  

              (f) Superseding Adjustment of Conversion Price.  If, at any time
    after any adjustment of the Conversion Price shall have been made pursuant
    to the foregoing SECTION 8.3(d) or 8.3(e) on the basis of the issuance of
    warrants or other rights or the issuance of other Convertible Securities,
    or after any new adjustment of the Conversion Price shall have been made
    pursuant to this SECTION 8.3(f):

                   (1) all of such warrants, options or rights or the right of
         conversion or exchange in such other Convertible Securities shall
         expire, and none of such warrants, options or rights, or the right of
         conversion or exchange in respect of such other Convertible

                                      - 40 -
<PAGE>

         Securities, as the case may be, shall have been exercised; or

                   (2) the consideration per share, for which Additional Shares
         of Nonpreferred Stock are issuable pursuant to all of such warrants,
         options or rights or the terms of all of such other Convertible
         Securities, shall be increased solely by virtue of provisions therein
         contained for an automatic increase in such consideration per share
         upon the arrival of a specified date or the happening of a specified
         event, and none of such warrants, options or rights, or the right of
         conversion or exchange in respect of such other Convertible
         Securities, as the case may be, shall have been exercised;

    such previous adjustment shall be rescinded and annulled and the Additional
    Shares of Nonpreferred Stock which were deemed to have been issued by
    virtue of the computation made in connection with the adjustment so
    rescinded and annulled shall no longer be deemed to have been issued by
    virtue of such computation.  Thereupon, a recomputation shall be made of
    the effect of such warrants, rights or options or other Convertible
    Securities on the basis of treating any such warrants, options or rights or
    any such other Convertible Securities which then remain outstanding as
    having been granted or issued immediately after the time of such increase
    of the consideration per share for such Additional Shares of Nonpreferred
    Stock are issuable under such warrants or rights or other Convertible
    Securities; and, if and to the extent called for by the foregoing
    provisions of this SECTION 8.3 on the basis aforesaid, a new adjustment of
    the Conversion Price shall be made, which new adjustment shall supersede
    the previous adjustment so rescinded and annulled.

              (g) Other Provisions Applicable to Adjustments Under this
    SECTION.  The following provisions shall be applicable to the making of
    adjustments of the Conversion Price hereinbefore provided for in this
    SECTION 8.3:

                                      - 41 -
<PAGE>

                   (1) Treasury Stock.  The sale or other disposition of any
         issued shares of Nonpreferred Stock owned or held by or for the
         account of the Company shall be deemed an issuance thereof for
         purposes of this SECTION 8.3.

                   (2) Computation of Consideration.  To the extent that any
         Additional Shares of Nonpreferred Stock or any Convertible Securities
         or any warrants, options or other rights to subscribe for or purchase
         any Additional Shares of Nonpreferred Stock or any Convertible
         Securities shall be issued solely for cash consideration, the
         consideration received by the Company therefor shall be deemed to be
         the amount of cash received by the Company therefor, or, if such
         Additional Shares of Nonpreferred Stock or Convertible Securities are
         offered by the Company for subscription, the subscription price, or,
         if such Additional Shares of Nonpreferred Stock or Convertible
         Securities are sold to underwriters or dealers for public offering
         without a subscription offering, the initial public offering price, in
         any such case excluding any amounts paid or receivable for accrued
         interest or accrued dividends and without deduction of any
         compensation, discounts or expenses paid or incurred by the Company
         for and in the underwriting of, or otherwise in connection with, the
         issue thereof.  The consideration for any Additional Shares of
         Nonpreferred Stock issuable pursuant to any warrants, options or other
         rights to subscribe for or purchase the same shall be the
         consideration received or receivable by the Company for issuing such
         warrant, options or other rights, plus the additional consideration
         payable to the Company upon the exercise of such warrants, options or
         other rights.  The consideration for any Additional Shares of
         Nonpreferred Stock issuable pursuant to the terms of any Convertible
         Securities shall be the consideration received or receivable by the
         Company for issuing any warrants or other rights to subscribe for or
         purchase such Convertible Securities, plus the consideration paid or
         payable to the Company in respect of the 

                                      - 42 -
<PAGE>

         subscription for or purchase of such Convertible Securities, plus 
         the additional consideration, if any, payable to the Company upon 
         the exercise of the right of conversion or exchange in such 
         Convertible Securities.  To the extent that any issuance shall be 
         for a consideration other than solely for cash, then, except as 
         herein otherwise expressly provided, the amount of such consideration 
         shall be deemed to be the fair value of such consideration at the 
         time of such issuance as determined pursuant to the Valuation 
         Procedure.

                   (3) When Adjustments to be made.  The adjustments required
         by the preceding subsections of this SECTION 8.3 shall be made
         whenever and as often as any specified event requiring an adjustment
         shall occur, except that no adjustment of the Conversion Price that
         would otherwise be required shall be made (except in the case of a
         subdivision or combination of shares of the Nonpreferred Stock as
         provided for in SECTION 8.3(a)) unless and until such adjustment,
         either by itself or with other adjustments not previously made, adds
         or subtracts at least $0.05 to the Conversion Price, as determined in
         good faith by the Board of Directors of the Company.  Any adjustment
         representing a change of less than such minimum amount shall be
         carried forward and made as soon as such adjustment, together with
         other adjustments required by this SECTION 8.3 and not previously
         made, would result in a minimum adjustment.  For the purpose of any
         adjustment, any specified event shall be deemed to have occurred at
         the close of business on the date of its occurrence.

                   (4) Fractional Interests.  In computing adjustments under
         this SECTION 8.3, fractional interests in Nonpreferred Stock shall be
         taken into account to the nearest one-thousandth of a share.

                   (5) When Adjustment Not Required.  If the Company shall take
         a record of the holders of its 

                                      - 43 -
<PAGE>


         Nonpreferred Stock for the purpose of entitling them to receive 
         a dividend or distribution or subscription or purchase rights 
         and shall, thereafter and before the distribution thereof 
         to shareholders, legally abandon its plan to pay or deliver
         such dividend, distribution, subscription or purchase rights, then
         thereafter no adjustment shall be required by reason of the taking of
         such record and any such adjustment previously made in respect 
         thereof shall be rescinded and annulled.

              (h) Merger, Consolidation or Disposition of Assets.  In case the
    Company shall merge or consolidate into another corporation, or shall sell,
    transfer or otherwise dispose of all or substantially all of its property,
    assets or business to another corporation and pursuant to the terms of such
    merger, consolidation or disposition, shares of common stock of the
    successor or acquiring corporation are to be received by or distributed to
    the holders of Nonpreferred Stock of the Company, then each holder of a
    share of the 1996 Series A Preferred Stock shall have the right thereafter
    to receive, upon exercise of such share of the 1996 Series A Preferred
    Stock, shares of common stock each comprising the number of shares of
    common stock of the successor or acquiring corporation receivable upon or
    as a result of such merger, consolidation or disposition of assets by a
    holder of the number of shares of Common Stock into which one share of the
    1996 Series A Preferred Stock could be converted immediately prior to such
    event.  If, pursuant to the terms of such merger, consolidation or
    disposition of assets, any cash, shares of stock or other securities or
    property of any nature whatsoever (including warrants or other subscription
    or purchase rights) are to be received by or distributed to the holders of
    Nonpreferred Stock of the Company in addition to common stock of the
    successor or acquiring corporation, then the Conversion Price in effect
    shall be adjusted to that number determined by multiplying the Conversion
    Price then in effect by a fraction (x) the numerator of which shall be the
    Fair Market Price per share of Common Stock immediately prior to the
    closing of such merger, consolidation or disposition minus the portion
    applicable to one share of Common Stock of any

                                      - 44 -


<PAGE>

    such cash so distributable and of the fair value of any such shares of 
    stock or other securities or property so received or distributed and 
    (y) the denominator of which shall be the Fair Market Price per share of
    Common Stock immediately prior to the closing of such merger, 
    consolidation or disposition.  The fair value of any such shares of stock
    or other securities or property shall be determined pursuant to the 
    Valuation Procedure.  In case of any such merger, consolidation or 
    disposition of assets, the successor acquiring corporation shall expressly
    assume the due and punctual observance and performance of each and every 
    covenant and condition hereof to be performed and observed by the Company 
    and all of the obligations and liabilities hereunder, subject to such 
    modification as shall be necessary to provide for adjustments to the 
    Conversion Price which shall be as nearly equivalent as practicable to the
    adjustments provided for in this SECTION.  For the purposes of this SECTION,
    "common stock of the successor or acquiring corporation" shall include stock
    of such corporation of any class, which is not preferred as to dividends or
    assets over any other class of stock of such corporation and which is not 
    subject to redemption, and shall also include any evidences of 
    indebtedness, shares of stock or other securities which are convertible 
    into or exchangeable for any such stock, either immediately or upon the 
    arrival of a specified date or the happening of a specified event, and any
    warrants or other rights to subscribe for or purchase any such stock.  The
    foregoing provisions of this SECTION 8.3(h) shall similarly apply to 
    successive mergers, consolidations or dispositions of assets.

              (i) Other Action Affecting Nonpreferred Stock.  In case at any
    time or from time to time the Company shall take any action affecting its
    Nonpreferred Stock, other than an action described in any of the foregoing
    SECTIONS 8.3(a) through (h), inclusive, then, unless in the opinion of the
    Board of Directors such action will not have a materially adverse effect
    upon the rights of the holders of the 1996 Series A Preferred Stock, the
    Conversion Price shall be adjusted in such manner and at such time as the
    Board of 



                                  - 45 -

<PAGE>

    Directors may in good faith determine to be equitable in the circumstances.

         8.9.  NO IMPAIRMENT.  Other than in connection with the amendment of
its Articles of Incorporation approved by the requisite number of stockholders,
the Company will not, through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid the observance or performance of any of the terms to be
observed or performed hereunder by the Company but will at all times in good
faith assist in the carrying out of all the provisions of this SECTION 8 and in
the taking of all such action as may be necessary or appropriate in order to
protect the conversion rights of the holders of the 1996 Series A Preferred
Stock against impairment.  Without limiting the generality of the foregoing, the
Company (i) will not permit the par value of any shares of stock at the time
receivable upon the conversion of the 1996 Series A Preferred Stock to exceed
the Conversion Price then in effect, (ii) will take all such action as may be
necessary or appropriate in order that the Company may validly and legally issue

Conversion Shares or any part thereof and that such Holder is prepared to 
bear the economic risk of retaining the 1996 Series A Preferred Stock and the 
Conversion Shares for an indefinite period, all without prejudice, however, 
to the right of such Holder at any time, in accordance with this Agreement, 
lawfully to sell or otherwise dispose of all or any part of the 1996 Series A

the Conversion Shares will be sold or offered for sale without registration 
under said Act or the availability of an exemption therefrom or if said Act 
is not applicable, all as more fully provided in SECTION 4, nor in violation 
of any other law of the United States of America or any state.

         2.5.  EXPENSES. Whether or not the 1996 Series A Preferred Stock is 
sold to any Holder, the Company will pay all costs and expenses incurred by 
the Holders (a) relating to the negotiation, execution and delivery of this 
Agreement and the issuance of the 1996 Series A Preferred Stock (including, 
without limitation, fees, office charges and expenses of counsel to the 
Holders, Milbank, Tweed, Hadley & McCloy and reasonable third party 
engineering, outside accounting and other out-of-pocket costs), (b) provided 
for in SECTIONS 4.6, 4.7, 5.1 and 5.2, (c) relating to printing the 
instruments evidencing the 1996 Series A Preferred Stock or the Conversion

this Agreement and (e) incident to the enforcement by any Holder of, or the 
protection or preservation of any right or remedy of any Holder under, this 
Agreement, the Articles of Incorporation, the Certificate of Designation or 
any other document or agreement furnished pursuant hereto or thereto or in 
connection herewith or therewith (including, without limitation, fees and 
expenses of counsel).  The Company shall pay such costs and expenses, to the 
extent then payable, on the date of issuance of the 1996 Series A Preferred 
Stock or, with respect to those matters described in clauses (b), (c), (d) 
and (e) above thereafter from time to time upon demand by any Holder against 
presentation, in each such case, of a statement thereof.  The Company shall 
also pay any fees or disbursements incurred by Weisser, Johnson & Co. or any 
person other than a party engaged solely by TCW in connection with 
identifying the Holders to whom the offers and sales of the shares of the 
1996 Series A Preferred Stock were made.

         2.6.  CONVERSION OPTION. On or after the second anniversary of the 
Closing Date, the Company shall have the option, at any time, to convert, in 
whole but not in part, the 1996 Series A Preferred Stock, on the terms and

due 2008 (the "DEBENTURES") having an aggregate principal amount equal to the 
Liquidation Value (as defined in the Certificate of Designation) of the 1996 
Series A Preferred Stock, PROVIDED THAT all of the following conditions are 
satisfied:  (i) the Company shall have delivered to the Holders all necessary 
approvals, subordination agreements and other documentation, in form and 
substance satisfactory to TCW in its reasonable discretion,


                                     - 8 -
<PAGE>
                                       
required in connection with such conversion (which will include such 
provisions acceptable to TCW in its reasonable discretion, which will entitle 
the holders of such Debentures to the same voting and other rights as if they 
held the 1996 Series A Preferred Stock including without limitation the right 
to vote as a separate class with respect to any plan of reorganization in a 
bankruptcy or insolvency proceeding relating to the Company) and (ii) the 
Holders shall have received an opinion of counsel to the Company (a) that 
such conversion neither breaches nor violates any existing agreement to which 
the Company is a party or any other obligation of the Company, (b) such 
conversion shall not cause an adjustment in the conversion price, option 
price or exercise price in any convertible security issued by the Company, 
and (c) such other matters as TCW may reasonably request. In the event that 
the Company exercises the option set forth in this SECTION 2.6 and the 
Company had not received before June 30, 1997 at least $15,000,000 of net 
cash proceeds from the issuance and sale by the Company of Common Stock which 
was not issued and outstanding on the Closing Date, the Company shall redeem 
annually on each of June 30, 2006, June 30, 2007 and June 30, 2008, one third 
(1/3) of the original principal amount of the Debentures.  The Debentures 
shall be subject to redemption at the option of the Company by the issuance 
of Freely Tradeable Common Stock (as defined in the Certificate of 
Designation) in the manner and subject to the terms and conditions of a 
conversion of the 1996 Series A Preferred Stock at the option of the Company 
pursuant to Section 8.3 of the Certificate of Designation but otherwise the 
Debentures shall not be redeemable at the option of the Company.  The 
Debentures shall be redeemed by the Company on June 30, 2008 at par value 
with all unpaid and accrued interest. The Debentures shall bear interest at a 
rate of 8.75% per annum, compounded quarterly, which interest payments shall 
be payable quarterly on March 31, June 30, September 30 and December 31 of 
each year commencing on the first of such date to occur immediately following 
the conversion option set forth in this SECTION 2.6.  Interest on the 
Debentures shall be paid in cash; PROVIDED, HOWEVER, that if any such 
interest payment is not paid on the penultimate Business Day of the month 
after the quarterly payment date on which it is due (the "INTEREST PAYMENT 
DATE"), the holders of the Debentures shall have the option to require the 
Company to pay such accumulated interest in shares (whether

whole or fractional) of Freely Tradeable Common Stock valued at the Cash 
Equivalent Amount (as defined in the Certificate of Designation) for the 
purposes of determining the number of shares (or fraction thereof) of Freely 
Tradeable Common Stock to be issued.

         4.1.  RESTRICTIVE LEGEND.  Unless and until otherwise permitted by this
SECTION 4, each certificate for 1996 Series A Preferred Stock issued under this
Agreement, each certificate for any 1996 Series A Preferred Stock issued to any
subsequent transferee of any such certificate, each certificate for any
Conversion Shares other than (i) Redemption Shares, (ii) Dividend Shares, (iii)
Conversion Shares issued upon the exercise by the Company of the conversion
rights granted pursuant to Section 8.3 of the Certificate of Designation and
(iv) each certificate for any Conversion Shares issued to any subsequent
transferee of any such certificate, shall be stamped or otherwise imprinted with
a legend in substantially the following form:

         "The shares evidenced by this certificate have not been registered
    under the Securities Act of 1933, as amended, and may be reoffered and sold
    only if registered pursuant to the provisions of said Securities Act or if
    an exemption from registration is available."

         4.2.  NOTICE OF PROPOSED TRANSFERS.  Prior to any transfer or attempted
transfer of any Restricted Securities not covered by the proviso contained in
the introductory paragraph to SECTION 4, the holder of such Restricted
Certificate shall give written notice to the Company of such holder's intention
to effect such transfer.  Each such notice (i) shall describe the manner and
circumstances of the proposed transfer in sufficient detail, and (ii) shall be
accompanied (except in transactions in compliance with Rule 144) by either (A) a
written opinion of legal counsel who shall be reasonably satisfactory to the
Company (provided that, in the case of any holder which is a person or an entity
affiliated with the TCW Funds, Trustco or Tamco, any counsel which is a
director, officer or employee of any such Person, shall be satisfactory to the
Company) to the effect that the proposed transfer of the Restricted Securities
may be effected without registration under the Securities Act, or (B) a "no
action" letter from the Commission to the effect that the transfer of such
securities without registration will not result in a recommendation by the staff
of the Commission that enforcement action be taken with respect thereto,
whereupon the holder of such Restricted Securities shall be entitled to transfer
such Restricted Securities in accordance with the terms



                                 - 17 -

<PAGE>

of the notice delivered by the holder to the Company.  Each certificate 
evidencing the Restricted Securities thus to be transferred (and each 
certificate evidencing any untransferred balance of the Restricted Securities 
evidenced by such Restricted Certificate) shall bear the restrictive legend 
set forth in SECTION 4.1.

         4.3. DEMAND REGISTRATION.  Subject to the limitations contained in
SECTION 4.6, at any time and from time to time, the holders of at least 51% of
the outstanding 1996 Series A Preferred Stock and Conversion Shares may give
written notice to the Company (i) of their intention to convert all or part of
the 1996 Series A Preferred Stock held by them and to transfer the Conversion
Shares held or obtained by conversion of 1996 Series A Preferred Stock and (ii)
requesting the registration of said Conversion Shares, and thereupon, the
Company shall, as expeditiously as possible, effect the registration of such
Conversion Shares under the Securities Act.  Such Sellers shall have the right
to select the managing underwriter or underwriters for the offering of such
Conversion Shares.

         In the case of an underwritten public offering of Restricted
Securities to be so registered pursuant to a registration under this SECTION
4.3, if the managing underwriter advises in its opinion that (i) the inclusion
in such registration of some or all of such Common Stock requested to be
registered (including without limitation, securities to be included pursuant to
incidental or "piggyback" rights heretofore or hereafter granted by the Company
to other Persons) will cause the proceeds or price per share to the Sellers to
be reduced or (ii) that the number of securities to be registered at the request
of the Sellers pursuant to this SECTION 4.3 plus the number of securities sought
to be registered by such other Persons is too large a number to be reasonably
sold, then the number of securities to be included in such registration will be
reduced as set forth below:

              (i)  the number of shares of Common Stock sought to be registered
    by the Company or any holders of Common Stock, other than the Conversion
    Shares and the Other Shares (as defined below), shall be reduced pro rata
    to the extent 

                                     - 18 -
<PAGE>

    necessary to reduce the number of securities to be registered
    to the number recommended by the managing underwriter (the "RECOMMENDED
    NUMBER"); 

              (ii)  if the reduction provided for in clause (i) above does not
    reduce the number of shares of Common Stock to be registered to the
    Recommended Number, then the number of Other Shares sought to be registered
    shall be reduced pro rata, in proportion to the number of shares of Common
    Stock sought to be registered by the holders of such Other Shares, to the
    extent necessary to reduce the number of shares of Common Stock to be
    registered to the Recommended Number; and

              (iii)  if the reductions provided for in clauses (i) and (ii)
    above do not reduce the number of shares of Common Stock to be registered
    to the Recommended Number, then the number of Conversion Shares sought to
    be registered shall be reduced pro rata, in proportion to the number of
    shares of Common Stock sought to be registered by the holders of such
    Common Stock, to the extent necessary to reduce the number of shares of
    Common Stock to be registered to the Recommended Number;

PROVIDED, that in no event shall the holders of the Conversion Shares so
included in such registration be required to pay any expenses relating to such
registration, including, without limitation, all the expenses described in the
first paragraph of SECTION 4.6, which are related to the inclusion of any other
holders' Common Stock in the registration.

         The Company shall have the right to include in any registration
pursuant to this SECTION 4.3, Common Stock held by its management which the
Company shall desire to have registered (collectively, "Other Stock"), PROVIDED,
that (i) such Other Stock shall not comprise more than ten (10) percent of
Conversion Shares included in the registration and (2) the managing underwriter
approves of the inclusion of such Other Stock in such registration as not having
an adverse impact on the price to be received by the holders of Conversion
Shares therein.

                                     - 19 -

         The Company will not grant to any Person at any time on or after the
date hereof the right (a "PIGGYBACK RIGHT") to request the Company to register
any securities of the Company under the Securities Act by reason of the exercise
by any Holder of its rights under this SECTION 4.3 unless such Piggyback Right
provides that such securities shall not be registered and sold at the same time
if the managing underwriter for the respective Sellers believes that sale of
such securities would adversely affect the amount of, or price at which, the
respective Conversion Shares being registered under this SECTION 4.3 can be
sold.

         The Company agrees (a) not to effect any public or private sale or
distribution of its equity securities, including a sale pursuant to Regulation D
under the Securities Act but excluding (i) a sale or distribution which the
Company is obligated to make pursuant to an acquisition or other agreement in
effect as of the date the holders of the 1996 Series A Preferred Stock or
Conversion Shares give notice under the first sentence of this SECTION 4.3, (ii)
the issuance of not more than 100,000 shares of Common Stock per calendar
quarter in connection with the Company's acquisition of (A) mineral leases, (B)
gas gathering systems, (C) pipelines, (D) producing and non-producing oil and
gas properties, and (E) other similar oil and gas assets (which shall not be
made during the 10-day period prior to, and during the 20-day period beginning
on, the closing date described below), and (iii) the issuance of shares of
Common Stock either (A) pursuant to the warrants and options listed on Schedule
3.1.1 in connection with the exercise thereof or (B) pursuant to one or more
underwritten public offerings after the Closing Date and on or before June 30,
1997 at a price per share less than the Conversion Price but not less than $4.00
and/or the exercise of the IPO Warrants (as defined in the Certificate of
Designation) at a price of $5.50 per share on or before November 12, 1998,
PROVIDED, THAT in the aggregate such shares shall not exceed 5,750,000 shares of
Common Stock, during the 10-day period prior to, and during the 120-day period
beginning on, the closing date of an underwritten offering made pursuant to a
registration statement filed pursuant to this SECTION 4.3 and (b) to cause each
holder of its privately placed equity securities purchased from the Company at
any time on or after the date of this 

                                     - 20 -
<PAGE>

Agreement to agree not to effect any public sale or distribution of any such 
securities during such period, including a sale pursuant to Rule 144 under 
the Securities Act (except as part of such underwritten registration, if 
permitted).

         Except pursuant to a registration statement filed pursuant to this
SECTION 4.3, each Holder agrees not to effect any public sale or distribution,
including a sale pursuant to Rule 144 or 144A under the Securities Act, of any
Restricted Securities during the 10-day period prior to, and during the 120-day
period beginning on, the closing date of an underwritten offering made pursuant
to a registration statement filed pursuant to this SECTION 4.3.

         The Company recognizes that money damages may be inadequate to
compensate Holders for a breach by the Company of its obligations under this
SECTION 4.3, and the Company agrees that in the event of such a breach the
Holders may apply for an injunction of specific performance or the granting of
such other equitable remedies as may be awarded pursuant to the arbitration
described in SECTION 6.9 below or by a court of competent jurisdiction after the
arbitration in SECTION 6.9 below in order to afford Holders the benefits of this
SECTION 4.3 and that the Company shall not object to such application, entry of
such injunction or granting of such other equitable remedies on the grounds that
money damages will be sufficient to compensate the Holders.

         4.4. PIGGY-BACK REGISTRATION.  Subject to the limitations contained 
in SECTION 4.6, if the Company at any time proposes to register any of its 
securities under the Securities Act on Form S-1, S-2 or S-3 or the equivalent 
(other than an Excluded Registration), whether of its own accord or at the 
request of any holder or holders of such securities, it will each such time 
give written notice to all holders of outstanding 1996 Series A Preferred 
Stock and Conversion Shares of its intention so to do.

         Upon the written request of a holder or holders of any such 1996
Series A Preferred Stock and Conversion Shares given within 30 days after
receipt of any such notice (stating the

                                     - 21 -


<PAGE>

intended method of disposition of such securities by the prospective Seller 
or Sellers), the Company will use its best efforts to cause all Conversion 
Shares, the holders of which shall have so requested registration thereof, to 
be registered under the Securities Act, all to the extent requisite to permit 
the sale or other disposition (in accordance with the intended methods 
thereof as aforesaid) by the prospective Seller or Sellers of the Conversion 
Shares so registered; PROVIDED, HOWEVER, the Company may elect not to file a 
registration statement pursuant to this SECTION 4.4 or may withdraw any 
registration statement filed pursuant to this SECTION 4.4 at any time prior 
to the effective date thereof.  In the case of an underwritten public equity 
offering by the Company, each Seller shall, if requested by the managing 
underwriter, agree not to sell publicly any equity securities of the Company 
held by such Seller (other than the Conversion Shares so registered) for a 
period of up to 120 days following the effective date of the registration 
statement relating to such offering.

         If the managing underwriter for the respective offering advises that
the inclusion in such registration of some or all of the Conversion Shares
sought to be registered by the Seller in its opinion will cause the proceeds or
price per unit the Company or the requesting or demanding holder of securities
will derive from such registration to be reduced or that the number of
securities to be registered at the instance of the Company or such requesting or
demanding holder plus the number of securities sought to be registered by the
Sellers is too large a number to be reasonably sold, then the number of
securities to be included in such registration will be reduced as set forth
below:

              (i)  the number of shares of Common Stock sought to be registered
    by any holders of Common Stock, other than the Conversion Shares, shall be
    reduced pro rata to the extent necessary to reduce the number of securities
    to be registered to the Recommended Number;

              (ii)  if the reduction provided for in clause (i) above does not
    reduce the number of securities to be registered to the Recommended Number,
    then the number of shares of the Common Stock sought to be issued and

                                     - 22 -
<PAGE>


    registered on account of the Company shall be reduced to the extent
    necessary to reduce the number of shares of Common Stock to be registered
    to the Recommended Number; and

              (iii)  if the reduction provided for in clauses (i) and (ii)
    above does not reduce the number of shares of Common Stock to be registered
    to the Recommended Number, then the number of Conversion Shares sought to
    be registered shall be reduced pro rata, in proportion to the number of
    Conversion Shares sought to be registered by the holders thereof, to the
    extent necessary to reduce the number of shares of Common Stock to be
    registered to the Recommended Number.

         The Company will not grant to any Person at any time on or after the
date hereof the right to request the Company to register any securities of the
Company under the Securities Act unless such right provides that such securities
shall not be registered and sold at the same time if the managing underwriter
for the respective sellers believes that sale of such securities would adversely
affect the amount of, or price at which, the respective Conversion Shares being
registered under this Section 4.4 can be sold.

         4.5. REGISTRATION PROCEDURES.  If and whenever the Company is 
required by the provisions of this SECTION 4 to use its best efforts to 
effect the registration of any of the Conversion Shares under the Securities 
Act, the Company will (except as otherwise provided in this Agreement), as 
expeditiously as possible:

              (a)  cooperate with any underwriters for, and the Sellers of, 
    such Conversion Shares, and will enter into a usual and customary
    underwriting agreement with respect thereto and take all such other
    reasonable actions as are necessary or advisable to permit, expedite and
    facilitate the disposition of such Conversion Shares in the manner
    contemplated by the related registration statement in each case to the same
    extent as if all the securities then being offered were for the account of
    the Company and the Company will provide to any Seller of Conversion
    Shares, any 

                                     - 23 -
<PAGE>

    underwriter participating in any distribution thereof pursuant to 
    a registration statement, and any attorney, accountant or other agent
    retained by any Seller or underwriter, reasonable access to appropriate
    Company officers and employees to answer questions and to supply
    information reasonably requested by any such Seller, underwriter, attorney,
    accountant or agent in connection with such registration statement;

              (b)  furnish or cause to be furnished to each Seller of Conversion
    Shares covered by such registration statement, addressed to such Sellers, a
    copy of the opinion of counsel for the Company, and a copy of the "comfort"
    letter signed by the independent public accountants who have certified the
    Company's financial statements included in the registration statement, 
    delivered on the closing date to the underwriters of such Conversion Shares;

              (c)  prepare and file with the Commission a registration statement
    with respect to such securities and use its best efforts to cause such 
    registration statement to become and remain effective; and prepare and file
    with the Commission such amendments and supplements to such registration 
    statement and the prospectus used in connection therewith as may be 
    necessary to keep such registration statement effective and to comply with
    the provisions of the Securities Act with respect to the sale or other 
    disposition of all securities covered by such registration statement 
    whenever the Seller or Sellers of such securities shall desire to sell or
    otherwise dispose of the same; PROVIDED that no such registration
    statement will be filed by the Company until counsel for the Sellers of
    securities included therein shall have had a reasonable opportunity to
    review the same and to exercise their rights under clause (a) above with
    respect thereto and no amendment to any such registration statement naming
    such Sellers as selling shareholders shall be filed with the Commission
    until such Sellers shall have had at least seven days to review such
    registration statement as originally filed and theretofore amended, to
    exercise their rights under clause (a) above and 

                                     - 24 -
<PAGE>

    to approve or disapprove any portion of such registration statement 
    describing or referring to such Sellers;

              (d)  furnish to each Seller such numbers of copies of a summary
    prospectus or other prospectus, including a preliminary prospectus, in 
    conformity with the requirements of the Securities Act, and such other
    documents, as such Seller may reasonably request in order to facilitate the
    public sale or other disposition of the securities owned by such Seller;

              (e)  use its best efforts to register or qualify the securities
    covered by such registration statement under such other securities or blue
    sky laws of such jurisdictions as each Seller shall request, and do any and
    all other acts and things which may be necessary or advisable to enable
    such Seller to consummate the public sale or other disposition in such
    jurisdictions of the securities owned by such Seller, except that the
    Company shall not for any such purpose be required to qualify to do
    business as a foreign corporation in any jurisdiction wherein it is not so
    qualified or to file therein any general consent to service;

              (f)  in the event of the issuance of any stop order suspending
    the effectiveness of any registration statement or of any order suspending
    or preventing the use of any prospectus or suspending the qualification of
    any Conversion Shares for sale in any jurisdiction, use its best efforts
    promptly to obtain its withdrawal;

              (g)  otherwise use its best efforts to comply with all applicable
    rules and regulations of the Commission;

              (h)  make available to its security holders, as soon as
    reasonably practicable, an earnings statement covering the period of at
    least twelve months, beginning with the first fiscal quarter beginning
    after the effective date of the registration statement, which earnings
    statement shall satisfy the provisions of Section 11(a) of the Securities
    Act; and

                                     - 25 -
<PAGE>

              (i)  list such securities on any securities exchange on which
    any stock of the Company is then listed, if the listing of such securities
    is then permitted under the rules of such exchange;

PROVIDED, HOWEVER, that notwithstanding any other provision of this SECTION 4,
the Company shall not be required to maintain the effectiveness of any
registration statement for a period in excess of two years (plus any period
during which the effectiveness of such registration has been suspended) except
that from time to time after a transfer of Conversion Shares pursuant to a
registration statement the Company will file all reports required to be filed by
it under the Securities Act and the Securities Exchange Act of 1934, as amended,
and the rules and regulations adopted by the Commission thereunder, and will
take such further action as any holder or holders of Conversion Shares may
reasonably request, all to the extent required to enable such holders to sell
Conversion Shares pursuant to Rule 144 and Rule 144A promulgated under the
Securities Act (or any successor thereto).  Upon written request, the Company
will deliver to such holders a written statement as to whether it has complied
with such requirements.

         4.6. EXPENSES; LIMITATIONS ON REGISTRATION.  All expenses incident 
to the Company's performance of its obligations in connection with any 
registration of the Sellers' Conversion Shares under this Agreement 
including, without limitation, printing expenses, fees and disbursements of 
counsel for the Company, fees of the National Association of Securities 
Dealers, Inc. in connection with its review of any offering contemplated in 
any registration statement and expenses of any special audits and independent 
engineering reports to which the Company shall agree or which shall be 
necessary to comply with governmental requirements in connection with any 
such registration shall be paid by the Company.  In connection with each 
Reimbursable Registration (as defined below in this SECTION 4.6), the Company 
shall pay (i) all registration and filing fees for the Sellers' Conversion 
Shares under Federal and State securities laws, (ii) expenses of complying 
with the securities or blue sky laws of any jurisdictions pursuant to SECTION 
4.5(e), and (iii) fees and expenses of not more than one special counsel for 
the Seller or 


                                     - 26 -
<PAGE>

Sellers but shall not be obligated to pay underwriter's discount or 
commissions with respect to the Conversion Shares.  In connection with any 
registration of any Conversion Shares which is not a Reimbursable 
Registration, all expenses of the kind specified in the preceding sentence 
shall be borne by the respective Seller or Sellers in such proportions as 
they may agree.

         It shall be a condition precedent to the obligation of the Company to
take any action pursuant to this SECTION 4 in respect of the Conversion Shares
which are to be registered at the request of any prospective Seller that (i)
subject to the immediately preceding paragraph, the Company shall have received
an undertaking satisfactory to it from such prospective Seller to pay, or have
deducted from the proceeds from the sale of Conversion Shares pursuant to a
registration, all expenses to be incurred by or for the account of and required
to be paid by such Seller, and (ii) such prospective Seller shall furnish to the
Company such information regarding the securities held by such Seller and the
intended method of disposition thereof as the Company shall reasonably request
and as shall be required in connection with the action to be taken by the
Company.

         The Holders of 1996 Series A Preferred Stock and Conversion Shares
shall be entitled to an aggregate of two effective registrations pursuant to
requests made under SECTION 4.3; PROVIDED, that any registration request made by
the requisite number of Holders, as set forth in the first paragraph of SECTION
4.3, which request shall be withdrawn (other than by reason of the Company's
failure to perform its obligations hereunder or a material adverse change in its
financial position or business) by the holders of at least 75% of the shares
evidenced or covered by the Conversion Shares sought to be registered, after the
respective registration statement shall have become effective, shall be treated
as an "effective" registration for purposes hereof.  Each registration which
either uses up one of the two registration rights granted in the preceding
sentence or is filed pursuant to a request subsequently withdrawn for any of the
reasons set forth in the final parenthetical clause of the preceding sentence
and each "piggy-

                                     - 27 -

<PAGE>

back" registration pursuant to SECTION 4.4 shall be deemed a "Reimbursable 
Registration."

         The Company agrees that it will not file a registration statement 
under the Securities Act, either for securities held by any of the Company's 
security holders other than holders of 1996 Series A Preferred Stock and 
Conversion Shares or for securities newly issued by the Company, until 30 
days after the effective date of any registration statement filed pursuant to 
the request of a Seller or Sellers made under SECTION 4.3.

         4.7.  INDEMNIFICATION.

         4.7.1.  In the event of any registration of any of its securities 
under the Securities Act pursuant to this SECTION 4, the Company shall 
indemnify and hold harmless the Seller of such Conversion Shares, such 
Seller's directors and officers, and each other person, if any, who controls 
such Seller within the meaning of the Securities Act (a "CONTROLLING 
PERSON"), against any losses, claims, damages or liabilities, joint or 
several, to which such Seller or any such director or officer or Controlling 
Person may become subject under the Securities Act or any other statute or at 
common law, insofar as such losses, claims, damages or liabilities (or 
actions in respect thereof) arise out of or are based upon (i) any alleged 
untrue statement of any material fact contained, on the effective date 
thereof, in any registration statement under which such securities were 
registered under the Securities Act, or in any preliminary prospectus or 
final prospectus contained therein, or any amendment or supplement thereto, 
or (ii) any alleged omission to state therein a material fact required to be 
stated therein or necessary to make the statements therein not misleading, 
and shall reimburse such Seller or such director, officer or Controlling 
Person for any legal or any other expenses reasonably incurred by such Seller 
or such director, officer or Controlling Person in connection with 
investigating or defending any such loss, claim, damage, liability or action; 
PROVIDED, HOWEVER, that the Company shall not be liable in any such case to 
the extent that any such loss, claim, damage or liability arises out of or is 
based upon any alleged untrue statement or alleged omission made in such 
registration statement, preliminary prospectus,


                                     - 28 -
<PAGE>
                                       
prospectus, or amendment or supplement in reliance upon and in conformity 
with written information furnished to the Company through an instrument duly 
executed by such Seller specifically for use therein.  Such indemnity shall 
remain in full force and effect regardless of any investigation made by or on 
behalf of such Seller or such director, officer or Controlling Person, and 
shall survive the transfer of such securities by such Seller.

         4.7.2.  Each holder of any Conversion Shares shall, by acceptance 
thereof, indemnify and hold harmless the Company, its directors and officers 
and each other person, if any, who controls the Company against any losses, 
claims, damages or liabilities, joint or several, to which the Company or any 
such director or officer or any such person may become subject under the 
Securities Act or any other statute or at common law, insofar as such losses, 
claims, damages or liabilities (or actions in respect thereof) arise out of 
or are based upon (i) any untrue statement or omission of any material fact 
contained, on the effective date thereof, in any registration statement under 
which securities were registered under the Securities Act, or in any 
preliminary prospectus or final prospectus contained therein, or any 
amendment or supplement thereto, or (ii) any omission to state therein a 
material fact required to be stated therein or necessary to make the 
statements therein not misleading, in each case to the extent, but only to 
the extent that such untrue statement or omission was contained in written 
information furnished to the Company through an instrument duly executed by 
such holder specifically for use therein, and shall reimburse the Company or 
such director, officer or other person for any legal or any other expenses 
reasonably incurred in connection with investigating or defending any such 
loss, claim, damage, liability or action.

         4.7.3.  INDEMNIFICATION similar to that specified in SUBSECTIONS 
4.7.1 and 4.7.2 shall be given by the Company and each holder of any 
Conversion Shares (with such modifications as shall be appropriate) to any 
underwriter with respect to any required registration or other qualification 
of any Conversion Shares under any Federal or state law or regulation of 
governmental authority.  The indemnity and expense reimbursements obligations 
of the Company and the Holders under SUBSECTIONS


                                     - 29 -
<PAGE>
                                       
4.7.1 and 4.7.2 shall be in addition to any liability the Company and the 
Holders may otherwise have.

         4.7.4.  Each Person (an "INDEMNITOR") who under the preceding 
provisions of this SECTION 4.7 agrees to indemnify another Person (an 
"INDEMNITEE") shall have the right, subject to the provisions hereto, to 
designate counsel (acceptable to the Indemnitee) to defend any case or 
proceeding against the Indemnitee arising in respect of any claim of 
liability for which such INDEMNIFICATION may be claimed, to the end that 
duplication of legal expense may be minimized; provided that, if the 
Indemnitee notifies the Indemnitor that the former has been advised by its 
counsel that any single counsel in such case or proceeding would have a 
conflict of interest in representing both the Indemnitor and the Indemnitee, 
the Indemnitee may designate its own counsel in such case or proceeding and, 
to the extent so provided above in this SECTION 4.7, shall be entitled to be 
reimbursed for its legal expenses reasonably incurred in connection with 
defending itself in such case or proceeding.

         4.8.  TERMINATION OF RESTRICTIONS.  Notwithstanding the foregoing 
provisions of this SECTION 4, the restrictions imposed by this SECTION 4 upon 
the transferability of the Restricted Securities shall cease and terminate as 
to any particular Restricted Security when such Restricted Security shall 
have been effectively registered under the Securities Act and sold by the 
holder thereof in accordance with such registration or sold under Rule 144 or 
144A promulgated by the Commission.  Whenever the restrictions imposed by 
this SECTION 4 shall terminate as to any Restricted Certificate, as 
hereinabove provided, the holder thereof shall be entitled to receive from 
the Company, without expense, a new certificate not bearing the restrictive 
legend otherwise required to be borne thereby.

         4.9.  RULE 144.  At all times, in order to permit the holders of 
1996 Series A Preferred Stock and Conversion Shares to sell the same, if they 
so desire, pursuant to Rule 144 or 144A promulgated by the Commission (or any 
successor to such rule), the Company will comply with all rules and 
regulations of the Commission applicable in connection with use of Rule 144 
and 144A (or any successor rules thereto), including the provision of 


                                     - 30 -
<PAGE>
                                       
information concerning the Company and the timely filing of all reports with 
the Commission in order to enable such holders, if they so elect, to utilize 
Rule 144 or 144A, and the Company will cause any restrictive legends to be 
removed and any transfer restrictions to be rescinded with respect to any 
sale of 1996 Series A Preferred Stock or Conversion Shares which is exempt 
from registration under the Securities Act pursuant to Rule 144 or 144A.

         SECTION 5.  COVENANTS OF THE COMPANY 

         5.1.  DELIVERY EXPENSES. If any Holder surrenders any certificate 
for 1996 Series A Preferred Stock or Conversion Shares to the Company or a 
transfer agent of the Company for exchange for instruments of other 
denominations or registered in another name or names, the Company will, 
subject to the provisions of SECTION 4, cause such new instruments to be 
issued and will pay the cost of delivering to or from the office of the 
Holder from or to the Company or its transfer agent, duly insured, the 
surrendered instrument and any new instruments issued in substitution or 
replacement for the surrendered instrument.

         5.2.  TAXES. The Company will pay all taxes (other than Federal, 
State or local income taxes) which may be payable in connection with the 
execution and delivery of this Agreement or the issuance and sale of the 1996 
Series A Preferred Stock and Conversion Shares hereunder or in connection 
with any modification of the 1996 Series A Preferred Stock or Conversion 
Shares and will save the Holders harmless without limitation as to time 
against any and all liabilities with respect to or resulting from any delay 
in paying, or omission to pay such taxes.  The obligations of the Company 
under this SECTION 5.2 shall survive any redemption, repurchase or 
acquisition of 1996 Series A Preferred Stock or Conversion Shares by the 
Company and the termination of this Agreement.

         5.3.  REPLACEMENT OF INSTRUMENTS. Upon receipt by the Company of

Conversion Shares, and

               (a) in the case of loss, theft or destruction, of indemnity
    reasonably satisfactory to it (provided that, if the owner of the same is a
    commercial bank or an institutional lender or investor, its own agreement
    of indemnity shall be deemed to be satisfactory), or

               (b) in the case of mutilation, upon surrender and cancellation
    thereof,

the Company, at its expense, will execute, register and deliver, in lieu 
thereof, a new certificate or instrument for (or covering the purchase of) an 
equal number of shares of 1996 Series A Preferred Stock or Conversion Shares.

         5.4.  RESTRICTIONS ON CERTAIN ACTIONS. From and after the date 
hereof to the day immediately following the issuance of 1996 Series A 
Preferred Stock hereunder the Company will not:

               (a) pay or declare any dividend payable in shares of its
    common stock or take any other action which, if taken after the date of
    such issuance, would result under the terms of the Preferred Stock in a
    change in the number of Conversion Shares into which the 1996 Series A
    Preferred Stock may be converted; or

               (b) make any amendment to the Articles of Incorporation of the
    Company, or file any resolution of the board of directors with the Nevada

    adversely affect or otherwise impair the rights of the holders of the 1996
    Series A Preferred Stock.

         5.5.  USE OF PROCEEDS. The Company shall use the proceeds of the 
sale of the 1996 Series A Preferred Stock as follows:

                    MAGNUM COMPLETES PRIVATE PLACEMENT OF 
                  $10 MILLION IN CONVERTIBLE PREFERRED STOCK

Irving, Texas, December 9, 1996, MAGNUM PETROLEUM, INC. ("Magnum") announced 
today it has executed the definitive agreements concerning the private 
placement of $10 million in convertible preferred stock with Trust Company of 
the West and TCW Asset Management Company, as agent for certain institutional 
investors (collectively herein referred to as "TCW").  Terms of the 1996 
Series A Convertible Preferred Stock call for (1) a fixed annual cumulative 
dividend rate of 8.75%, payable quarterly in arrears commencing December 31, 
1996, (2) convertibility into common shares of the Company at a conversion price
of $5.875 per share, and (3) if not already converted, an option by the Company
after two years to exchange the 1996 Series A Convertible Preferred Stock for 
a Convertible Subordinated Debenture of equivalent value.  Financial funding 
of the equity placement is anticipated prior to year-end and will be applied 
to the Company's senior bank credit facility.  As a condition of the private 
placement, when required, the Company will fund the capital costs necessary 
for developing existing proved oil and gas properties owned by the Company by 
utilizing the availability under its existing senior bank credit facility.

Commenting on this new convertible preferred stock issue, Mr. Gary C. Evans, 
President and CEO of Magnum, stated "We are pleased to have completed this 
significant transaction for Magnum with TCW,  an institution with an 
excellent reputation in the energy industry.  We have been working diligently 
on this transaction for several months and are pleased to have reached terms 
and conditions which we believe are most satisfactory to the Company and will 
allow our new institutional investors to participate in the upside potential 
of the Company.  As part of the conditions of the private placement, Magnum 
will significantly increase the development plans on the Company's proved 
properties over the next twelve months."

MAGNUM PETROLEUM, INC. is an exploration and development company engaged in 
four principal activities: (1) the acquisition, production and sale of crude 
oil, condensate and natural gas; (2) the gathering, transmission and marketing
of natural gas; (3) the managing and operating of producing oil and natural gas
properties for interest owners; and (4) providing consulting and U.S. export 
services to facilitate Latin American trade in energy products.
                                       
                                     #####

The information in this release includes certain forward-looking statements 
that are based on assumptions that in the future may prove not to have been 
accurate. Those statements, and Magnum Petroleum, Inc.'s business and 
prospects, are subject to a number of risks, including volatility of oil and 
gas prices, the need to develop and replace reserves, the substantial capital 
expenditures required to fund its operations, environmental risks, drilling 
and operating risks, risks related to exploration and development drilling, 
uncertainties about estimates of reserves, competition, government 
regulation, and the ability of the company to implement its business 
strategy.  These and other risks are described in the company's reports that 
are available from the SEC.
