ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------

RESULTS OF OPERATIONS

     THREE MONTHS ENDED DECEMBER 31, 1995 AS COMPARED WITH THREE MONTHS ENDED
DECEMBER 31, 1994.

     During the three months ended December 31, 1995, the Company earned all
revenues and incurred the majority of its expenses in connection with the
operations of its Miami Subs Grill restaurants.  The Company had five Miami Subs
Grill in operation during the quarter.

     During the three months ended December 31, 1995, the Company had restaurant
revenues of $1,160,809, a decrease of $218,332, or 15.8%, from restaurant
revenues of $1,379,131 generated during the three months ended December 31,
1994; approximately $124,000 of this decrease is attributable to sales at the
Company's Houston restaurant, which the Company sold in November 1994.  The
Company has also experienced decreases in revenues at all of its remaining
restaurants that were in operation during both periods.  These decreases were
offset by sales of $214,867 at a new restaurant opened in September 1995. The
Company believes that the factors that gave rise to, and adverse publicity
connected with, the recently settled litigation described in Item 1 of Part II
this Report, have adversely affected the sales at all of its restaurants, all of
which are located in the Dallas, Texas area.

     The costs and expenses incurred in connection with restaurant operations-
food and beverage expenses, restaurant, labor expenses, operating expenses and
depreciation of amortization on restaurant equipment were $1,175,985 during the
three months ended December 31, 1995, a decrease of $149,928 or approximately
11.4%, from the $1,318,913 incurred during the three months ended December 31,
1994.  Approximately $102,000 of this decrease is attributable to expenses
incurred at the Company's Houston restaurant during the quarter ended December
31, 1994.  The following table shows the percentage of restaurant operating
expenses to restaurant sales during the quarters ended December 31 of 1995 and
1994:

                                           1995               1994

                                 --------  ----------  --------  ----------
Food and beverage..............  $401,664      34.6    $530,568     38.5
Restaurant labor...............   379,157      32.7     467,469     33.9
Restaurant operating expense...   330,919      28.5     242,213     17.6
Depreciation and amortization..    64,245       5.5      78,663      5.7

Food and beverage and labor expenses declined as a percentage of sales due to
better cost controls.

                                       1

     The restaurant operating loss (i.e. the revenues less the expenses incurred
with restaurant operations) was $15,176 during the three months ended December
31, 1995, as compared to the restaurant operating profits of $60,218 during the
three months ended December 31, 1994.

     The Company is not producing the "SportsWaves!" broadcast during the
current fiscal year, primarily because of uncertainties raised in the Company's
litigation with the landlord of the Southwestern Boulevard Restaurant.  During
the quarter ended December 31, 1994, the Company had revenues from broadcast
operations of $295,368 and total expenses of $267,597.  Management believes that
the inability to broadcast the SportsWaves! program during the current fiscal
year and the corresponding loss of broadcast media exposure and promotion has
had a material adverse impact on restaurant operations.

     General and administrative expenses for the three months ended December 31,
1995 were $200,883, an increase of $33,697, or approximately 20.2% from general
and administrative expenses of $167,186 during the three months ended December
31, 1994.  Such expenses increased primarily because of legal expenses incurred
in connection with the recently settled litigation described in Item 1 of Part
II of this Report.

     The Company experienced a one-time gain of $10,903 in connection with the
forgiveness of indebtedness owed by the Company to several of its suppliers.
The Company has reached settlements with such vendors which involve, in part,
the issuance of Company common stock in exchange for such debt.

     NINE MONTHS ENDED DECEMBER 31, 1995 AS COMPARED WITH NINE MONTHS ENDED
DECEMBER 31, 1994.

     During the nine months ended December 31, 1995, the Company earned all
revenues and incurred the majority of its expenses in connection with the
operations of its Miami Subs Grill restaurants.  The Company had four Miami Subs
Grill in operation during the entire period and opened a new restaurant on
September 25, 1995.  During this nine month period, the Company was involved in
negotiations with Stephens Diversified Leasing, Inc., dba/Stephens Franchise
Finance ("Stephens") to obtain financing that would permit the completion of the
restaurant then under construction and to convert a substantial portion of the
Company's short term indebtedness to long term debt.  See "Liquidity and Capital
Resources," below.

     During the nine months ended December 31, 1995, the Company had restaurant
revenues of $3,284,026, a decrease of $1,435,086, or approximately 30.4%, from
restaurant revenues of $4,719,112 generated during the nine months ended
December 31, 1994.  Approximately $695,627 of this decrease is attributable to
sales at the Company's Houston restaurant during the nine months ended December
31, 1994; the Company sold this restaurant in November 1994.  This decrease was
partially offset by revenues of $238,805 at the Company's new restaurant located
in Mesquite, Texas that opened in September 1995. The Company has also
experienced decreases in revenues at all of its restaurants that were in
operation during both periods; the Company believes that the factors that gave
rise to the recently settled litigation, described in Part II, Item 1 of this
Report, and adverse publicity connected with such litigation, have adversely
affected the sales at all of its restaurants, all of which are located in the
Dallas, Texas area.  See Part II, Item 1--"Legal Proceedings."

     The costs and expenses incurred in connection with restaurant operations -
food and beverage expenses, restaurant, labor expenses, operating expenses and
depreciation of amortization on restaurant equipment - were $3,280,384 during
the nine months ended December 31, 1995, a decrease of $1,349,783 or
approximately 29.2%, from the $4,630,167 incurred during the nine months ended
December 31, 1994. Approximately $653,098 of this decrease is attributable to
expenses incurred at the Company's Houston

restaurant during the nine months ended December 31, 1994 (net of insurance
proceeds of approximately $86,781 received during such nine-month period).  The
following table shows the percentage of restaurant operating expenses to sales
during the nine month periods ended December 31, 1995 and 1994:
 
                                          1995                   1994

                                   Amount    of sales     Amount     of sales
                                 ---------- ----------  ----------  ----------
Food and beverage..............  $1,131,794    34.5     $1,755,828     36.9
Restaurant labor...............   1,046,009    31.9      1,557,241     33.6
Restaurant operating expense...     928,039    28.3      1,079,807     23.3
Depreciation and amortization..     174,542     5.3        237,291      5.1

Food and beverage and labor expenses declined as a percentage of sales due to
better cost controls. Restaurant operating expenses increased as a percentage of
sales primarily because of the effect of reduced sales and because of the
aforementioned insurance settlement in the approximate amount of $86,781
received in 1994.

     The restaurant operating profits (i.e. the revenues less the expenses
incurred with restaurant operations) was $3,642 during the nine months ended
December 31, 1995, as compared to the restaurant operating profits of $88,945
during the nine months ended December 31, 1994.

     General and administrative expenses for the nine months ended December 31,
1995 were $575,478, an increase of $35,812, or approximately 6.6% from general
and administrative expenses of $539,936 during the nine months ended December
31, 1994.  The increase occurred primarily because of expenses incurred in
connection with the Company's refinancing efforts, its efforts to raise
additional capital, legal fees incurred in litigation relating to the
Southwestern Boulevard Restaurant and arising as a result of the Company's cash
flow difficulties.

     The Company experienced a one time a gain of $473,981 in connection with
the forgiveness of indebtedness it owed to several of its suppliers.  The
Company has reached settlements with such vendors which involve, in part, the
issuance of Company common stock in exchange for such debt.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's cash and cash equivalents at December 31, 1995 were $100,398.
Cash flows from operations were a negative $1,414,254 for the nine months ended
December 31, 1995 compared to a positive $315,671 during the same period in
1994.  The increase in cash used in operating activities was due principally to
the use of the proceeds of the loan from Stephens to reduce accounts payable.

     Cash used in investing activities was $352,887 in the nine months ended
December 31, 1995 as compared to cash used of $1,241,447 during this same period
in 1994.  The decrease in cash used reflected the reduced purchase of property
and equipment during this period.

     Cash flows from financing activities were $1,802,845 during the nine month
period ended December 31, 1995 compared to $389,998 during this same period in
1994.  This increase reflected the proceeds of the loan (the "Stephens Loan")
from Stephens Diversified Leasing, Inc. ("Stephens") and proceeds from the sale
of an aggregate of $424,000 of common stock of the Company sold as a condition
of receiving the Stephens Loan, both of which are described below.  The Company
also negotiated reduction in certain accounts payable and settlement of
litigation arising from such accounts payable in the

                                       3
<PAGE>
 
form of reductions in payment and/or issuance of common stock of the Company in
exchange for all or a portion of such indebtedness.  At various times during the
nine month period, the president of the Company advanced funds to the Company to
meet various short term obligations..

     At a meeting held June 27, 1995, the Board of Directors of the Company
voted to issue to each member of the Board of Directors options to purchase
45,000 shares of common stock of the Company (an aggregate of 315,000 shares) at
an exercise price of $.16 2/3 per share until August 26, 1995 and to lower the
exercise price of outstanding options previously issued to directors to $.16 2/3
per share until the same date, after which the exercise price would revert to
the original exercise price.  In a unanimous consent of the Board of Directors
dated October 13, 1995, the exercise period for both the new option s and for
the reduced exercise price of the existing options was subsequently extended
until October 15, 1995. Options exercisable for a total of 108,921 shares were
exercised on or before October 15.

     At its June 27, 1995 meeting, the Board of Directors also agreed to reduce
the exercise price of outstanding warrants from $16.67 per share to $.16 2/3 per
share and to extend the exercise period of such warrants to December 31, 1995.
The Board also agreed to grant each warrant holder an additional warrant to
purchase an equal number of shares on or before December 31, 1995 at $.16 2/3
per share. A total of 395,002 warrants were exercised during their exercise term
at the reduced option exercise price.

     Mr. Solomon's employment agreement with the Company, dated as of June 28,
1995, grants to Mr. Solomon an option to purchase 300,000 shares of common stock
at $.23 1/3 per share.  Subsequent to December 31, Mr. Solomon exercised this
option.

     The Company experienced a one time a gain of $473,981 in connection with
the forgiveness of indebtedness it owed to several of its suppliers.  The
Company has reached settlements with such vendors which involve, in part, the
issuance of Company common stock in exchange for such debt.

     The Company has granted to holders of its warrants and to the holders of
certain of its shares certain piggyback registration rights that generally are
at the Company's expense.

     Stephens Loan Agreement.  As of June 30, 1995, the Company entered into the
Loan Agreement with Stephens pursuant to which the Company has borrowed a total
or $1,500,000 from Stephens.  As a condition of the Loan Agreement, the Company
was required to raise at least $400,000 of additional equity capital; the
Company sold an aggregate total of 2,544,000 shares of its common stock at a
price of $.16 2/3, for a total of $424,000.  The Stephens Loan is secured by a
lien against substantially all of the Company's assets.  As of December 31,
1995, Stephens had advanced the Company a total of $1,500,000. Outstanding
borrowings accrue interest at 13.40% until October 31, 2000; from November 1,
2000 to October 31, 2002, outstanding amounts will bear interest at Stephens'
then outstanding rate.  The proceeds of the Loan Agreement and the additional
capital were used to repay outstanding accounts receivable and to fund the
completion of the Town East Restaurant.

     The Stephens Loan is guaranteed by Miami Subs pursuant to the terms of the
Forbearance and Restructuring Agreement (the "Forbearance Agreement").  Under
this agreement, Miami Subs also agreed to forbear from the exercise of its
default rights that had arisen from the Company's past-due franchise fees and
other payments due (the "Miami Subs Debt") under the area development agreement
between the Company and Miami Subs (the "Area Development Agreement") and the
franchise agreements pursuant to which the Company operates the restaurants (the
"Franchise Agreement").  The Forbearance Agreement contains financial covenants
that require the Company to maintain a ratio of current assets to current
liabilities of at least 1.0 to 1.0 at the end of each fiscal quarter, beginning
December 31, 1995, maintain working capital of at least $100,000 at the end of
each fiscal quarter, beginning December 31, 1995, and

                                       4
<PAGE>
 
have a ratio of cash flow from operations as derived from the Company's year end
audited statement of cash flows (including net proceeds from the sales stock) to
required debt service payments (including payments on capital leases) for each
fiscal year of at least 1.1 to 1.0.  Miami Subs waived the Company's compliance
with the financial covenants until March 31, 1996.  Under the Forbearance
Agreement, upon the occurrence of an event of default Miami Subs may accelerate
the Miami Subs Debt, terminate the forbearance of its exercise of its default
rights under the area development agreement between the Company and Miami Subs
USA and the franchise agreements relating to the Company's restaurants, and
exercise its current default rights and any and all other rights pursuant to the
area development agreement between the Company and Miami Subs (the "Area
Development Agreement"), the franchise agreements. It is expected that, upon the
completion of the proposed sale of the Company's Miami Subs Grill restaurants to
Miami Subs, the Forbearance Agreement would be terminated.  See Item 5-Other
Information-Proposed Sale of Restaurants.

     The Loan Agreement and the Forbearance Agreement do not permit the Company
to pay or declare any cash or property dividends or otherwise make any
distribution of capital.

     If the proposed sale of the restaurants is not consummated, the Company
believes that it will need substantial additional funds to build and open new
Miami Subs Grill restaurants and to meet the development schedules set out in
the Area Development Agreement and for working capital to fund the operation of
the restaurants, to the extent such restaurants are not profitable.  In such
event, the Company may also have to seek to renegotiate the development
schedules and the financial covenants under the Forbearance Agreement, although
there is no assurance that it could  do so.  The Company anticipates that it
would need to seek additional funds, either through borrowing, through sales of
its securities, or a combination of both, in order to secure such funds.

     Future Financings.  The Company is conducting private offerings in which it
is seeking to raise up to $2,000,000 for the purpose of obtaining working
capital and for the purpose of providing funds to Citadel Computer Systems, Inc.
("Citadel") in connection with the proposed merger of the Company with Citadel.
See "Item 5-Other Information-Proposed Acquisition of Citadel Computer Systems,
Inc."  The offering consists of debentures and warrants.  The debentures will
bear interest at 12% per annum, and will mature 120 days from the date of
issuance, unless extended for an additional 30 day period by the Company.  The
warrants will be exercisable, in the aggregate, for up to 600,000 shares of
common stock.  In addition, up to 50,000 additional warrants may be issued to
brokers as compensation.  There is no assurance that the Company will be
successful in raising the amount sought in this private offering.

     The Company is preparing to conduct an offering pursuant to Regulation S
promulgated under the Securities Act of 1933 to overseas purchasers.  This
overseas offering will seek to raise up to $1,500,000 for working capital
purposes.  The offering will consist of units consisting of convertible
debentures and warrants.  The debentures will bear interest at 12% per annum,
will mature 120 days from the date of issuance (unless extended for up to an
additional 30 days by the Company) and will be convertible into shares of the
Company's common stock at a conversion price equal to 80% of the average closing
prices per share of the Company's common stock for 10 consecutive trading days
preceding the conversion date. The warrants will be exercisable, in the
aggregate, for up to 600,000 shares of common stock of the Company.

     The Company expects to engage in additional capital raising efforts
following the completion of the Citadel merger.   The Company and Citadel are
engaged in discussions with investment banking firms about such efforts, but
have not entered into any letter of intent with an investment banking firm or
determined the structure or amount of any such efforts.  There is no assurance
that the Company will be

                                       5
<PAGE>
 
successful in identifying or engaging an investment banking firm or that, if it
does so, it will be successful in raising capital in any such offering.

     Proposed Sale of Restaurants to Miami Subs USA, Inc.  The Company has
reached an agreement in principal to sell its five operating restaurants and its
franchise rights to Miami Subs.  This agreement in principal provides that the
Company will receive 1,325,000 shares of Miami Subs stock in exchange for the
restaurants and franchise, with an estimated value of $2,650,000, and that Miami
Subs will assume the Stephens Loan and that the Company will issue a new note to
Miami Sub in an amount approximately equal to the outstanding principal and
accrued interest under the Stephens Loan.  This sale is subject to several
conditions, including the completion of due diligence by Miami Subs, the
approval of Miami Subs' board of directors and of the lessors of the
restaurants' premises and equipment.  In addition, if the Citadel acquisition is
not consummated, the Company anticipates that it will elect not to proceed with
the sale of the restaurants.  Accordingly, there is no assurance that the sale
of the restaurants will occur.  It is expected that the Company would realize a
loss of approximately $1,600,000 on the sale of the restaurants.   See "Item 5-
Proposed Sale of Restaurants."

ITEM 5.  OTHER INFORMATION
- --------------------------

CERTAIN TRANSACTIONS

     As of November 13, 1995, the Company issued to Steven B. Solomon, the
President of the Company, 900,000 shares of common stock in exchange for the
cancellation of indebtedness totalling, in the aggregate, $150,000, or $.16 2/3
per share.  The Company had agreed in June 1995 to issue this stock in exchange
for the cancellation of indebtedness to Mr. Solomon in connection with the loan
from Stephens.  The Company had also issued 75,000 shares of common stock to the
prior holder of this indebtedness; such shares  are held by Axel Sawallich, a
director of the Company, in his capacity as a trustee for such prior holder.

     In October 1995, Messrs. Sawallich and  Solomon exercised options to
acquire an aggregate of 63,921 shares and 45,000 shares of common stock of the
Company, respectively, at an exercise price of $.16 2/3 per share.

     In June 1995, the Company issued to each member of the Board of Directors
options to purchase 45,000 shares of Company common stock at $.16 2/3 per share
until August 26, 1995 and to lower the exercise price of outstanding options
previously issued to directors to $.16 2/3 per share until the same date, after
which the exercise price would revert to the original exercise price.  The
exercise period for both the new option s and for the reduced exercise price of
the existing options was subsequently extended until October 15, 1995.

     Employment Agreement between Stephen B. Solomon and the Company.  In
December 1995 the Board approved an employment agreement between the Company and
Mr. Solomon dated as of June 28, 1995 and expiring on May 31, 2000.  The
employment agreement provides for an annual base salary or $120,000 during the
period from June 28, 1995 through May 31, 1996; $132,000 during the period from
June 1, 1996 through May 31, 1997; and $144,000 thereafter.  Mr. Solomon agreed
to defer receipt of his base salary payable during the period from June 28, 1995
through May 31, 1996 until the earlier of the date the Company (i) has a
positive cash flow, including general and administrative expenses and debt
service requirements, or (ii) has raised at least $1,000,000 in capital
(including both debt and equity), or (iii) has received at least $1,000,000 of
value in acquisition or merger for stock or substantially all the assets of the
Company.  In addition, upon the occurrence of the events described in (ii) or
(iii) above, Mr. Solomon may elect to receive a one-time bonus of $100,000.

     The Company shall provide life insurance in the amount of $1,000,000 on Mr.
Solomon's life, in addition to any key man life insurance maintained by the
Company for its benefit.  The Company shall provide Mr. Solomon with an
automobile allowance of $950 per month and automobile liability insurance.

     Mr. Solomon's employment agreement provides Mr. Solomon an option to
acquire 300,000 shares of common stock of the Company at an exercise price of
$.23 1/3 per share. Subsequent to December 31, 1995, Mr. Solomon has exercised 
this option.

     If the Company terminates Mr. Solomon's employment agreement for cause,
death or disability, Mr. Solomon will be entitled to any unpaid salary, bonus
and vacation pay.  If he is terminated otherwise than for cause, Mr. Solomon
will be entitled to a severance payment equal to the sum of any unpaid salary,
bonus and vacation pay, and the greater of (i) the remaining payments that would
have been made during the term of the employment agreement or any extension
thereof, discounted to present value using an

                                       7
<PAGE>
 
interest rate of 6%, or (ii) an amount determined by multiplying his base salary
for the most recently completed full month of employment by 24.  All severance
payments would be payable in a lump sum within 30 days after the effective date
of the termination of employment, and any options to purchase shares that would
be exercisable during the term of the employment agreement or any extension
thereof would become fully exercisable upon its termination.

PROPOSED ACQUISITION OF CITADEL COMPUTER SYSTEMS, INC.

     On January 31, 1996, Citadel Computer Systems, Inc, a Delaware corporation
("Citadel"), the Company and LSHC Acquisition, Inc., a wholly-owned Delaware
subsidiary of the Company ("Acquisition"), entered into an Agreement and Plan of
Merger (the "Merger Agreement"), whereby Citadel agreed, subject to certain
conditions, to merge into Acquisition (the "Merger").  Pursuant to the terms of
the Merger Agreement, each stockholder of Citadel will receive 4.5 shares of
common stock of the Company for each share of common stock of Citadel held by
such stockholder.   In addition, each outstanding option and warrant to purchase
capital stock of Citadel will become an option or warrant to purchase a number
of shares of Common Stock of the Company equal to four and one-half (4.5) times
the number of shares subject to the Citadel options and warrants at the same
aggregate exercise price of the Citadel options and warrants.

     Upon consummation of the Merger, the former stockholders of Citadel will
own approximately 75% of the issued and outstanding common stock of Company, and
current Company stockholders will own the remaining 25%, each on a fully diluted
basis, and each prior to the issuance of Common Stock in connection with the
acquisition of certain software products from Circuit Master, as described
below. As a result, a change of control in the Company will have occurred.

     In addition, the Merger Agreement provides that Gilbert  Gertner and George
Sharp will become directors of the Company and that, upon the expiration of 10
days from the date of an Information Statement Pursuant to Section 14(f) of the
Securities Exchange Act of 1934 and Rule 14f-1 thereunder, the sole directors of
the Company will be Messrs. Gertner, Sharp and Solomon.  During such 10 day
period, the Merger Agreement provides that the board of directors of the Company
will not take any action without the written consent of Messrs. Gertner and
Sharp.  It is expected that the Company will change its name to Citadel Computer
Systems, Inc. after the Merger.

     The Merger is subject to a number of conditions, and there is no assurance
that it will occur.  One such condition is that the Company must sell or enter
into an agreement to sell all of its restaurant assets owned by LS on terms
reasonably satisfactory to Citadel.  The Company and Miami Subs USA, Inc.
("Miami Subs") have entered into an agreement in principle regarding such sale,
as described below.  In addition, a condition to the Merger is that the Company
advance to Citadel $500,000 as an unsecured loan for a term of one year, bearing
interest at 12% per annum.

     Proposed Acquisition by Citadel.  Prior to consummation of the Merger,
Citadel reached an agreement with Circuit Master Software ("Circuit Master"), a
company that makes computer software, pursuant to which Citadel agreed to
purchase certain software products that complement Citadel's products. Upon
consummation of the Merger, the Company will assume Citadel's obligations under
this agreement with Circuit master, which will require the Company to issue
common stock of the Company to Circuit Master valued at $2,000,000 based on the
average closing trading price of the Company's common stock for the thirty (30)
trading days following the effective date of the Merger.

PROPOSED SALE OF RESTAURANTS

     The Company has reached an agreement in principle to sell its five Miami
Subs Grill restaurants in the Dallas, Texas area to Miami Subs Corporation, of
Fort Lauderdale, Florida ("Miami Subs").  In addition, Miami Subs will also
acquire LoneStar's right to develop additional Miami Subs Grill restaurants in
the Dallas/Fort Worth area and will assume LoneStar's indebtedness of $1,500,000
to Stephens Diversified Leasing, Inc. ("Stephens")  Miami Subs is also the
franchisor of the Miami Subs Grill restaurants.

     Under the proposed agreement, LoneStar will receive 1,325,000 shares of
Miami Subs common stock (the "Miami Subs Stock"), and Miami Subs will file a
registration statement with the Securities and Exchange Commission covering the
Miami Subs Stock within 60 days after the closing.  During the six months
following the closing, LoneStar will be not be able to sell any of the Miami
Subs Stock, except with the consent of Miami Subs, and Miami Subs will have the
right to acquire the Miami Subs Stock for $2.50 per share.  Thereafter, LoneStar
will be able to sell the Miami Subs Stock in private transactions, or in open
market transactions not to exceed 240,000 shares per calendar quarter or 20,000
shares per week. All sales by LoneStar will be subject to a right of first
refusal by Miami Subs.

     Miami Subs will assume no liabilities of LoneStar, except for LoneStar's
loan from Stephens. LoneStar will also issue to Miami Subs a promissory note in
the principal amount of up to $1,500,000, to be secured by the Miami Subs Stock.
The note will not bear interest and will be due on or before April 30, 1996.
The maturity date of the note will be extended to June 30, 1996 if LoneStar
makes a principal payment of $50,000 on or before April 30, 1996.

     This sale is subject to several conditions, including the negotiation and
execution of a definitive sale agreement, the completion  of due diligence on
restaurant operations  and other matters, review of contracts to be assumed by
Miami Subs and approval by Miami Subs' board of directors. It is expected that,
if the Merger does not occur, the Company would elect not to proceed with the
sale of the restaurants. There is no assurance that the sale will be
consummated.

                     --------------------------------------------------      
Citadel Common Stock shall be converted or canceled in the Merger as follows:

        Subject to SECTION 2.8, each certificate that prior to the Effective
Date represented outstanding shares of Citadel Common Stock will, after such
time, be deemed for all purposes to evidence only the right to receive four and
one-half (4.5) shares of LoneStar Common Stock.  No interest will accrue or be
payable with respect to the amounts payable upon exchange of certificates.  Any
shares of Citadel Common Stock held in the treasury of Citadel will be canceled
upon consummation of the Merger, and no consideration will be delivered in
exchange for those shares.  No share of Acquisition Common Stock shall be
affected in any manner by the consummation of the Merger.

        No fraction of a share of LoneStar Common Stock will be issued upon such
exchange of shares of Citadel Common Stock, but any holder of shares of Citadel
Common Stock who would otherwise be entitled to a

                                       4
<PAGE>
 
fraction of a shares of LoneStar Common Stock will instead receive a cash
payment in lieu of and with respect to said fraction of a share to which such
holder would be so entitled determined by multiplying (i) the value of a share
of LoneStar Common Stock (calculated as hereinafter provided) times (ii) the
fractional share interest to which such holder would otherwise be entitled,
which product shall be rounded to the nearest whole cent.  For purposes of
computing such cash payment, the value of a share of LoneStar Common Stock shall
be the average of the closing bid prices of LoneStar Common Stock on the OTC
Bulletin Board for the last five trading days prior to the Effective Time.  Such
cash payment shall be paid in U.S. dollars at the time of presentation for
surrender to the Transfer Agent of the certificate representing shares of
Citadel Common Stock.  The right to receive such cash payment shall, if the
holder thereof shall not prior thereto so present such certificate, terminate on
the second anniversary date of the Effective Time.

        At the Effective Time, each outstanding option and warrant to purchase
capital stock of Citadel, listed in SECTION 2.6 of the Citadel Disclosure
Schedule and outstanding immediately prior to the Effective Time, shall become
an option or warrant after the Effective Time to purchase a number of shares of
LoneStar Common Stock equal to four and one-half (4.5) times the number of
shares subject to the Citadel options and warrants set forth in SECTION 2.6 of
the Citadel Disclosure Schedule at the same aggregate exercise price as set
forth on Schedule 2.6 of the Citadel Disclosure Schedule, which is 22.2% of the
per share exercise price set forth in SECTION 2.6 of the Citadel Disclosure
Schedule; provided, however, that this provision shall not apply to the
outstanding contingent rights held by certain Citadel noteholders and set forth
in SECTION 2.6 of the Citadel Disclosure Schedule to acquire warrants to
purchase LoneStar Common Stock following the Merger.

             2.7 EXCHANGE OF CERTIFICATES. Promptly after the Effective Time,
                 ------------------------                                     
LoneStar shall cause the Transfer Agent to mail to each record holder, as of the
Effective time, of an outstanding certificate or certificates that immediately
prior to the Effective Time represented issued and outstanding shares of Citadel
Common Stock, a form letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the certificates shall pass,
only upon proper delivery of the certificates to the Transfer Agent) and
instructions for use in effecting the surrender of the certificates. Upon
surrender to the Transfer Agent of such certificate, together with such letter
of transmittal duly executed, each holder of such certificates formerly
representing shares of Citadel Common Stock shall be entitled to receive in
exchange therefor a certificate representing the whole number of shares of
LoneStar Common Stock into which such shares of Citadel Common Stock shall have
been converted as set forth herein and such certificates of Citadel Common Stock
shall then be canceled.

             2.8  APPRAISAL RIGHTS.
                  ---------------- 

             (a) Notwithstanding any other provision of this Agreement to the
        contrary, shares of Citadel Common Stock issued and outstanding
        immediately prior to the Effective Time and which are held by
        shareholders who object to the Merger and comply with all of the
        relevant provisions of the DGCL ("Dissenting Shares") shall not be
        converted into or represent a right to receive LoneStar Common Stock
        hereunder or pursuant to the Articles of Merger at or after the
        Effective Time, but instead shall be entitled to receive payment of the
        appraised value of such shares in accordance with the provisions of the
        DGCL, unless and until the holder thereof shall have failed to perfect,
        or shall have effectively withdrawn or lost, such rights to appraisal
        and payment under the DGCL.  If a holder of Dissenting Shares shall have
        so failed to perfect or shall have effectively withdrawn or lost such
        right to appraisal and payment, then as of the Effective Time or the
        occurrence of such event, whichever last occurs, such holder's
        Dissenting Shares shall be converted into and solely represent the right
        to receive shares of LoneStar Common Stock, as provided herein.  Citadel
        shall give LoneStar prompt notice upon receipt by Citadel of any written
        objection to the plan of merger set forth herein (any shareholder duly
        making such objection being hereinafter called a "Dissenting
        Shareholder").  Citadel agrees that prior to the Effective Time, it will
        not, without the prior written consent of LoneStar, voluntarily make or
        agree to make any payment with respect to, or settle or offer to settle,
        any such objection.

        the provisions of the DGCL, to payment for his Dissenting Shares shall
        receive payment therefor after the Effective Time from the Surviving
        Corporation (but only after the amount thereof shall have been agreed
        upon or finally determined pursuant to such provisions) and such shares
        shall be canceled.

             2.9     APPROVAL OF THE STOCKHOLDERS.  As soon as reasonably
                     ----------------------------

all applicable state and federal laws, obtain the approval of the Stockholders

consent of the board of directors of LoneStar, Acquisition and Citadel for any
reason; (ii) LoneStar or Acquisition, if Citadel has failed to comply in any

by LoneStar, Acquisition or Citadel if such delay is attributable to actions by
a Governmental Entity; (v) either LoneStar, Acquisition or Citadel, if a
Governmental Entity has permanently enjoined or prohibited consummation of the

abandonment pursuant to SECTION 11.1, this Agreement shall become void and have
no effect, without any liability on the part of any of the parties or their
directors or officers or stockholders in respect of this Agreement and the
transactions contemplated hereby except that a party that breaches this
Agreement may have liability to the other parties hereto arising out of such
breach.  Except as allowed under this Agreement, if the Merger is not

in connection therewith and the transactions contemplated thereby.

                  ------

                   ---------

amendment may be made after such approval if the amendment would change the

further approval of the stockholders so adversely affected.  The parties to this
Agreement may, at any time prior to the Effective Date, extend the time for
performance of any of the other parties' obligations under this Agreement and
waive any inaccuracies in the representations and warranties contained herein
