ITEM 5.  OTHER EVENTS.

     As previously reported, on May 17, 1995, a subsidiary of registrant entered
into an agreement to acquire Synergy Group Incorporated ("Synergy").  A copy of
that agreement is filed as exhibit 2 to this report.

     Synergy is subject to the informational requirements of the Securities
Exchange Act of 1934, as amended, and in accordance therewith files reports and
other information with the Securities and Exchange Commission ("Commission").
Information concerning Synergy, its business, assets and financial statements,
may be obtained from such filings which are available for inspection and copying
at the public reference facilities of the Commission at Room 1024, 450 Fifth
Street N.W., Washington, D.C. 20549, and at the Commission's Regional offices at
Suite 1400, Northwestern Atrium Center, 500 West Madison Street, Chicago,
Illinois 60661, and at Seven World Trade Center, 13th Floor, New York, New York
10048.  Copies of such material may be obtained from the Public Reference
Section of the Commission, 450 Fifth Street, N.W., Washington, D.C. 20549, at
prescribed rates.

     Under the terms of the agreement, the acquisition is subject to various
conditions and approvals, including the accuracy of various representations and
warranties made by the sellers as to the business, assets, financial condition
and results of operations of Synergy and its subsidiaries, the obtaining of
financing needed by registrant's subsidiary for the acquisition, the issuance of
orders by the Federal Energy Regulatory Commission authorizing the registrant's
issuance of the securities to provide for such financing, and the expiration or
termination of the waiting period for the acquisition under the Hart-Scott-
Rodino Antitrust Improvements Act of 1976.

     The acquisition is to be made in association with Empire Gas Corporation
("Empire Gas"), a large propane distribution company headquartered in Lebanon,
Missouri, which has a management experienced in the retail propane distribution
business.  Agreements have been entered into with Empire Gas (copies of which
are filed as exhibits 99.1 and 99.2 to this report)


                                       2

pursuant to which Empire Gas is to have an equity interest in the acquisition
and is engaged to perform the planning and management of the assets and business
operations to be acquired, subject to the direction of the Board of Directors of
the acquiring subsidiary of registrant.

     The acquiring subsidiary of registrant (with its immediate parent
corporation, Northwestern Growth Corporation, a wholly-owned subsidiary of
registrant) has granted to an unrelated third party an option to purchase
certain of the retail distribution outlets to be acquired from Synergy.  Under
the option, the purchase price is payable in cash and will be based on the price
paid to Synergy for such outlets.  Such cash price currently is estimated to be
approximately $40 million which would decrease the cash payment to be made for
the Synergy acquisition to approximately $100 million.

     Pro forma financial information for registrant, giving effect to the
acquisition, with and without the exercise of the third party purchase option,
is filed with this report.

ITEM 7.  FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS.
                               ---------

     (b)  PRO FORMA FINANCIAL INFORMATION.

     Set forth below are summary financial data extracted from the audited
consolidated statement of operations of the Company for the year ended December
31, 1994, the unaudited consolidated financial statements of the Company as of
March 31, 1995, and for the three months then ended; the summary financial data
extracted from the unaudited statement of operations of Synergy for the 12
months ended December 31, 1994 and for the three months ended March 31, 1995,
and balance sheet information as of March 31, 1995; and the pro forma financial
information for the Company ("the Pro Forma Financial Information")  for the
year ended December 31, 1994, for the three months ended March 31, 1995, and as
of March 31, 1995, based on such historical financial statements, to illustrate
the effects of the Acquisition. The Pro Forma Financial Information illustrates
the effects of the Acquisition as adjusted to give effect to the sale of a
certain part of the Synergy business and assets to an unrelated third party
pursuant to its option to acquire such businesses and assets and without
adjustments, assuming such sale will not occur. See Item 5 herein.

   The Acquisition will be accounted for using the purchase method of
accounting. After the Acquisition, the total purchase price of the Acquisition
will be allocated to Synergy's tangible and intangible assets and liabilities
based upon their respective fair values. The allocation of the aggregate
purchase price included in the Pro Forma Financial Information is preliminary,
but the final allocation of the purchase price is not expected to differ
materially from the preliminary allocation.  The financing plan to be executed
for the funding of the Acquisition is expected to be as presented in the Pro
Forma Financial Information.   Although market conditions may impact certain
financing options and assumptions as to interest and dividend rates, the overall
financing plan is not expected to vary materially from that presented.

     The pro forma statements of operations for the year ended December 31, 1994
and for the three months ended March 31, 1995, give effect to the Acquisition,
and the related transactions as if they had occurred on January 1, 1994. The pro
forma balance sheet as of March 31, 1995 has been prepared as if the transaction
had occurred on that date.  The pro forma financial information does not purport
to present the financial position or results of operations of the Company had
the Acquisition actually been completed as of the dates indicated.  In addition,
the pro forma financial information is not necessarily indicative of future
results of operations and should be read in conjunction with the historical
consolidated financial statements of the Company and Synergy which are reported
and filed with the Securities and Exchange Commission.

     The following pro forma information assumes that the above-mentioned sale
to an unrelated third party will be made as to a certain part of the Synergy
business and assets.

A) Represents all relevant statement of operations effects, net of income taxes,
   generated by the expected sale of certain Synergy properties to an unrelated
   third party. Although an option to sell certain properties has been executed
   and it is anticipated that such option will be exercised, in the event the
   option is not closed, pro forma net income available for common would have
   been $15,343,000 and $14,306,000; and pro forma net income per common share
   would have been $1.74 and $1.62 for the year ended December 31, 1994 and for
   the three months ended March 31, 1995, respectively. The following represents
   the estimated impact on pro forma net income available for common as

   All general and administrative functions previously performed at Synergy
   headquarters would be undertaken by Empire Gas, Inc. under a management
   agreement governing the operation of the Synergy properties.  (See Item 5
   herein.) Under the terms of the management agreement, Empire Gas will be
   compensated through a general and administrative charge and a management
   fee arrangement.

   affiliates of existing Synergy shareholders. Such property will be purchased
   as a part of the acquisition transaction. In addition, general and
   administrative expense savings include shareholder compensation.

   headquarters would be undertaken by Empire Gas, Inc. under a management
   agreement governing the operation of the Synergy properties.  (See Item 5

<PAGE>

Closing Date in Sections 1.6(b) and 1.6(c) hereof, (ii) a

working capital of the Company as of December 31, 1994, excluding

<PAGE>

Stockholders and including the Company's total litigation reserve
(the "December Amount")) and the Cash Component shall be
decreased by the amount by which the Working Capital of the
Company as of the Second Closing Date is less than the December
Amount (the Cash Component as so increased or decreased shall
hereinafter be referred to as the "Adjusted Cash Component").
Promptly after preparation and final determination, pursuant to
Section 1.7 hereof, of the Statement of Working Capital (as
defined in Section 1.6(c) hereof) (but in no event later than
three business days thereafter), if the Closing Date Amount is
less than the Adjusted Cash Component, Buyer shall, and if the
Closing Date Amount is more than the Adjusted Cash Component, the
Stockholders' Agent (as defined in Section 9.5 hereof) shall,
make payment to the other in cash of the amount of such
difference, together with an amount in cash equal to the interest
accrued thereon at an interest rate per annum equal to the
interest rate announced by Citibank, N.A. as its base rate,
calculated on the basis of the actual number of days elapsed from
the Second Closing Date to the date of payment divided by 365, by
wire transfer to the bank accounts designated by the party to
receive such funds at least one business day prior to the date of
such payment.

                               -8-

<PAGE>

          (c)  For purposes of this Agreement, the following
terms have the following meanings:

               (i)  "Statement of Working Capital" means a
consolidated statement of the Working Capital of the Company and
its consolidated subsidiaries as of the Second Closing Date
prepared from the books and records of the Company and its
consolidated subsidiaries, as adjusted to reflect the results of
any physical inventory taken by Buyer as of the Second Closing
Date, in accordance with generally accepted accounting principles
("GAAP"), without any requirement for consistency with the
Interim Statements (as defined in Section 4.5 hereof) (except as
set forth in the definition of Working Capital); and

               (ii)  "Working Capital" of the Company as of the
Second Closing Date means the consolidated current assets of the
Company and its consolidated subsidiaries, less all amounts with
respect to consolidated current liabilities of the Company and
its consolidated subsidiaries, excluding accrued interest and the
current portion of long-term debt and accruals for compensation
deferred by and payable to the Stockholders and including the
Company's total litigation reserve, calculated as of the close of
business on such date, without giving effect to the transactions
contemplated by this Agreement.

     1.7  DETERMINATION OF WORKING CAPITAL.  As promptly as
practicable, but not more than 90 days after the Second Closing

                               -9-

<PAGE>

Date, Buyer shall cause its accountants to prepare and deliver to
the Stockholders' Agent the Statement of Working Capital.  The
Stockholders' Agent and its authorized representatives shall be
entitled to review the Statement of Working Capital and the books
and records of the Company and its consolidated Subsidiaries and
the work papers used to prepare such Statement of Working
Capital.  If the Stockholders' Agent disagrees with any item on
the Statement of Working Capital, the Stockholders' Agent shall
notify Buyer in writing of such disagreement (stating the reasons
therefor) within 30 days after the Stockholders' Agent's receipt
of the Statement of Working Capital from Buyer, and Buyer and the
Stockholders' Agent shall attempt to resolve such disagreement.
If Buyer and the Stockholders' Agent are unable to agree in
writing on the Statement of Working Capital within 30 days after
receipt of the Stockholders' Agent's notice of disagreement,
Buyer and the Stockholders' Agent shall refer such disagreement
to a firm of independent certified public accountants (the
"Firm") selected and agreed to in writing by Buyer's accountant
and an accountant designated by the Stockholders' Agent.  The
Firm shall resolve any such disagreement and shall determine the
Statement of Working Capital resulting therefrom.  Such Statement
of Working Capital as determined by the Firm shall become the
Statement of Working Capital for purposes of this Agreement and
shall be conclusive and binding on all parties hereto.  If Buyer

                               -10-

<PAGE>

and the Stockholders' Agent agree in writing on the Statement of
Working Capital within 30 days after the Stockholders' Agent's
receipt of the Statement of Working Capital from Buyer or if the
Stockholders' Agent does not send a notice of disagreement within
30 days after receipt of the Statement of Working Capital, the
Statement of Working Capital for purposes of this Agreement shall
be the Statement of Working Capital received by the Stockholders'
Agent pursuant to the first sentence of this Section 1.7.  If
Buyer fails to cause its accountant to prepare and deliver the
Statement of Working Capital within 90 days after the Second
Closing Date, unless otherwise agreed to in writing by Buyer and
the Stockholders' Agent, the accountant designated by the
Stockholders' Agent shall have the right to prepare and deliver
to Buyer, and Buyer will provide access to the books and records
of the Company necessary or desirable to complete, the Statement
of Working Capital, and such Statement of Working Capital shall
be the Statement of Working Capital for purposes of this
Agreement.  Buyer and the Stockholders hereby agree that the cost
of the Firm shall be borne equally by Buyer, on the one hand, and
the Stockholders, on the other hand.

     1.8  CONTRACT ESCROW FUNDS.  Simultaneously with the Second
Closing, Buyer shall deliver to the Contract Escrow Agent, as
defined in and, pursuant to the Contract Escrow Agreement (as
defined in Section 6.17 hereof) (i) $6,250,000 in cash (the

<PAGE>

"Contract Escrow Cash") (ii) 2,500 shares of Buyer Series A
Preferred Stock, and (iii) the Promissory Note (the Promissory
Note, collectively with such shares of Buyer Series A Preferred
Stock and the Contract Escrow Cash, the "Contract Escrow Funds").

     1.9  C&L MATTERS ESCROW FUNDS.  Simultaneously with the
Second Closing, the following shall be delivered to the C&L
Matters Escrow Agent, as defined in and, pursuant to the C&L

$250,000 in cash (the "C&L Additional Amount");

          (b)  Buyer shall deliver, on behalf of the
Stockholders, an amount in cash equal to $4,000,000 less the C&L
Reserve and the C&L Additional Amount (the "C&L Stockholder

Additional Amount, the "C&L Matters Escrow Cash"); and

          (c)  Buyer shall deliver 17,500 shares of Buyer Common
Stock (such stock together with the C&L Matters Escrow Cash, the

                               -22-

<PAGE>

conducted.  Each of the Company and its Operating Subsidiaries is
duly qualified or licensed and in good standing to do business as
a foreign corporation in each jurisdiction in which the property
owned, leased or operated by it or the nature of the business
conducted by it makes such qualification necessary, except in any
such jurisdictions where the failure to be so duly qualified or
licensed and in good standing would not, individually or in the
aggregate, have a material adverse effect on the business,
properties, results of operations or financial condition of the
affected corporation.  Sellers have heretofore made available to
Buyer complete and correct copies of the Company's and its
Operating Subsidiaries' respective Certificates of Incorporation,
and By-Laws, as currently in effect.

     4.2  AUTHORITY.  (a)  Each of the Stockholders has the
capacity to execute and deliver this Agreement, the Stockholders'
Agreement, the Contract Escrow Agreement, the C&L Matters Escrow
Agreement and their respective Non-Competition Agreements (the
"Seller Documents") and to consummate the transactions
contemplated hereby and thereby, and the Company has the
corporate power and authority to execute and deliver this
Agreement and to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement by the Company and
consummation by the Company of the transactions contemplated
hereby have been

                               -23-

<PAGE>

duly and validly authorized by the Board of Directors of the
Company and the Stockholders, and except as contemplated by
Section 6.19 hereof, no other corporate proceedings on the part
of the Company or the Stockholders are necessary to authorize
this Agreement or the consummation of the transactions so
contemplated.  This Agreement has been, and the other Seller
Documents will be, duly executed and delivered by the Company, in
the case of this Agreement, and the Stockholders (or their
agent), in the case of the Seller Documents, and, assuming the
due and valid execution and delivery by Buyer of the Seller
Documents, by NGC of this Agreement and by the Contract Escrow
Agent of the Contract Escrow Agreement and by the C&L Matters
Escrow Agent of the C&L Matters Escrow Agreement, each
constitutes, and when executed and delivered will constitute, a
valid and binding agreement of each Seller, enforceable against
each of them in accordance with its terms, except (i) as such
enforceability may be limited by bankruptcy, insolvency,
moratorium, reorganization and other similar laws affecting
creditors' rights generally, and (ii) as such enforceability may
be limited by general principles of equity, regardless of whether
asserted in a proceeding in equity or law.

          (b)  S&J is a general partnership duly organized and
validly existing under the laws of its jurisdiction of formation
and has all requisite power and authority to own, lease and

                               -24-

<PAGE>

conducted.  S&J has the power and authority, under applicable law
and its organizational documents, to execute and deliver this
Agreement and to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement by S&J and the
consummation of the transactions by S&J contemplated hereby have
been duly and validly authorized by S&J, and the person executing
and delivering this Agreement on behalf of S&J has been
authorized to do so.  This Agreement has been duly executed and
delivered by S&J, and, assuming the due and valid execution and
delivery by Buyer of the Seller Documents and by NGC of this
Agreement, constitutes, and when executed and delivered will
constitute, a valid and binding obligation of S&J, enforceable
against S&J in accordance with its terms, except (i) as such
enforceability may be limited by bankruptcy, insolvency,
moratorium, reorganization and other similar laws affecting
creditors' rights generally, and (ii) as such enforceability may
be limited by general principles of equity, regardless of whether
asserted in a proceeding in equity or law.

all of the issued and outstanding shares of capital stock of the
Company.  The Shares are owned beneficially and of record by the
respective Stockholders in the amounts set forth opposite their
names on Section 4.3(a) of a disclosure schedule being delivered

Company issued or outstanding, or any options, warrants,

agreements or commitments obligating the Company to issue any
shares of capital stock or obligating the Stockholders, or
restricting the Stockholders' right, to transfer or sell any

Shares, free and clear of all options, pledges, security
interests, liens and encum-

                               -26-

<PAGE>

brances, other than any option, pledge, security interest, lien

affiliates.  There are no dividends which have been declared or
which have accrued on the Shares or the Series B Shares which are
unpaid.

          (b)  The Company currently conducts its operations and

names, jurisdictions of incorporation and number of shares of
capital stock outstanding of each of the Operating Subsidiaries
are set forth on Section 4.3(b) of the Disclosure Schedule.
Section 4.3(b) of the Disclosure Schedule also sets forth the

and entity owned or controlled by the Company (collectively, with

issued and outstanding shares of capital stock of the
Subsidiaries (the "Subsidiary Shares") are validly issued, fully
paid and nonassessable and are not subject to any preemptive
rights.  The Subsidiary Shares represent all of the issued and
outstanding shares of capital stock of the Subsidiaries, and,
assuming redemption of the Notes, there are no options, warrants,
convertible securities, calls, subscriptions or other rights,
agreements or commitments obligating any of the Subsidiaries to
issue any

                               -27-

<PAGE>

shares of its capital stock or obligating the Company, or
restricting the Company's right, to transfer or sell any
Subsidiary Shares.  The Subsidiary Shares are owned beneficially
and of record by the Company or a Subsidiary of the Company, free
and clear of all options, pledges, security interests, liens and
encumbrances, assuming redemption of the Notes.  Except for
securities of, or loans to, the Subsidiaries, the Company does
not directly or indirectly through a Subsidiary, own any capital
stock of or other equity interest in any corporation, partnership
or other business entity or have outstanding a loan made to any
such entity excluding normal extensions of credit in the ordinary
course of business.

promptly notify the Stockholders' Agent of the receipt of any
notice from any taxing authority of an audit or other contest of
the Company's or any of its Subsidiaries' Tax Returns for any

indemnify Buyer under Section 9.2(b) hereto.  The Stockholders'
Agent and Buyer shall act together in good faith and shall
jointly control, each at their own expense, any proceeding with

the Stockholders' Agent shall have primary responsibility and
sole authority, after consulting with Buyer, for communicating

necessary or desirable by such parties in connection with such
matters.  Neither the Stockholders' Agent nor Buyer shall have

          (a)  Buyer and NGC shall at all times comply with all

agree to, and to cause their respective affiliates and
representatives to, keep such information confidential and not to
hire the employees of the Company or any of its Subsidiaries for
a period of eighteen months from the date thereof; provided, that

the holders of all issued and outstanding Series A Notes.
Following the Second Closing, Buyer shall, and shall cause the

                               -74-

of such financing, as reasonably requested by Sellers.  Buyer and
NGC shall provide Sellers with all loan agreements relating to

with all reasonable requests for information with respect to the
Company made by Buyer in connection with NWPS, NGC and Buyer
obtaining the Temporary Financing, the Permanent Financing, and

and punctually perform or comply with such action, commitment or
obligation.  NGC hereby agrees that it shall not be necessary for
Sellers or S&J to give any notice to NGC, or make any request of

waives (i) demand by Sellers or S&J for performance of, or
failure by Buyer to perform, its obligations under or arising out

and (ii) all other notices for which NGC might otherwise be
entitled in connection with this guaranty.  If Buyer assigns any

Agreement through the Second Closing Date, Buyer shall not modify
or amend its certificate of incorporation or by-laws or amend the
terms of the Temporary Financing or the Permanent Financing in a
manner that would (i) adversely affect Buyer's and NGC's ability
to consummate the transactions contemplated hereby, or (ii) make
such financing more difficult to obtain.

     6.22  TITLE EXAMINATION.  Buyer shall have the right, at
Buyer's option and Buyer's sole cost and expense, to order title

purchase any of the Company's 11 % Senior Subordinated Notes due

than the principal amount (plus accrued interest thereon to the
date of redemption or purchase), Buyer shall pay to the

                               -79-

<PAGE>

Stockholders' Agent for the account of the Stockholders, as
additional purchase price for the Shares within ten days of such
redemption or purchase (but not earlier than the Second Closing
Date), the difference between the principal amount of such Senior
Subordinated Notes (plus accrued interest thereon to the date of
redemption or purchase) and the amount actually paid by such
person for such Senior Subordinated Notes.  The issued and

stock of Buyer as set forth in Section 5.8 hereof.

     6.25  TANK INVENTORY.  (a) The Stockholders will deliver at
the First Closing, the results of a physical inventory of the
consumer propane tanks owned by the Company and its Subsidiaries
which are held in inventory and a verification of executed tank
contracts, customer supply agreements executed by the customer

                               -80-

<PAGE>

relating to tanks with a capacity of 100 pounds or less which
states that the Company or the Subsidiary is providing the tank
for use by the customer (such agreement shall not be required to
list a serial number for the tank), work orders executed by the
customer (such work order shall include the serial number of the
tank), bills of sale, and tank supplier invoices, as of the First
Closing Date (the "Tank Inventory").  Buyer will be given
adequate advance notice of the inventory being taken and the
verification being performed and be permitted to have Buyer's
authorized representatives observe such process.

          (b)  As soon as practicable, but not later than 180
days after the First Closing Date, Buyer shall have the right to
dispute the Tank Inventory based on its own physical inventory or
otherwise as of the Second Closing Date by delivering a notice of
Claim pursuant to Article IX hereof.  In addition, Buyer shall
provide the Stockholders' Agent with periodic status reports with
respect to Buyer's verification of the Tank Inventory and within
90 days after the First Closing Date, Buyer shall provide the
Stockholders' Agent with a detailed report with respect to such
verification.  If Buyer does not dispute the Tank Inventory, the
Tank Inventory shall be binding for purposes of determining a
breach of Section 4.9(a) hereof with respect to ownership of
consumer propane tanks or the Tank Overage Amount (as defined in
Section 6.25(c) hereof).  The Stockholder's Agent shall have the

                               -81-

<PAGE>

opportunity to assist in establishing the Company's or any of its
Subsidiaries' good title as defined in Section 4.9(a) hereof to
such tank.  Buyer shall reasonably cooperate with the
Stockholders' Agent in such effort.  The final tank inventory
number, whether it be the Tank Inventory, an inventory agreed to
between Buyer and the Stockholders' Agent in writing, or an
inventory determined by an arbitrator, shall be the "Final Tank
Inventory".

          (c)  To the extent there exists a net deficiency (after
applying the credits referred to in Section 4.9(a) hereof) in the
number of consumer propane tanks on the Final Tank Inventory when
compared to the net number of tanks set forth on Section 4.9(a)
of the Disclosure Schedule (after applying the 5% "deductible"
referred to in Section 4.9(a) hereof), such deficiency shall be
reduced to an amount of Damages (as defined in Section 9.2(a)
hereof) determined by reference to the American Tank and Welding
new tank price for such types and sizes of tanks, plus shipping
costs, except that to the extent Buyer is able to acquire used
tanks of the same types and sizes which are in generally good
condition and fit for their intended use at a tank price plus
shipping costs that is less than the new tank price plus shipping
costs (from a source identified to Buyer by the Stockholders'
Agent), then such used tank price shall be used to determine
Damages.  Buyer shall provide the Stockholders' Agent with

                               -82-

<PAGE>

written notice of a deficiency and the Stockholders' Agent shall
have 30 days from receipt of such notice to identify used tanks
for purchase by Buyer.  To the extent the net number of tanks set
forth on the Final Tank Inventory is more than 5% greater than
the net number of tanks represented on Section 4.9(a) of the
Disclosure Schedule (after applying the credits referred to in
Section 4.9(a) hereof), then such overage shall be reduced to a
dollar amount by reference to 66-2/3% of the American Tank and
Welding new tank price, plus shipping costs, for such types and
sizes of tanks.  The aggregate dollar amount of such overage
shall be referred to herein as the "Tank Overage Amount."

     6.26  C&L MATTERS ESCROW AGREEMENT.  Simultaneously with the
Second Closing, Buyer, the Stockholders' Agent, on behalf of the
Stockholders, and the escrow agent named therein, shall enter
into an Escrow Agreement, substantially in the form attached
hereto as Exhibit D (the "C&L Matters Escrow Agreement").

     6.27  THE PROMISSORY NOTE.  The Promissory Note shall be
payable in three successive equal annual installments one each on
the first three anniversaries of the Second Closing Date, plus
interest then accrued but previously unpaid thereon as part of
each such installment; provided, that the unpaid principal
balance shall not bear interest during the first 12 months after
the date of issuance of the Promissory Note and thereinafter
shall bear interest at a rate of 9 1/2% per annum.  The Promis-

                               -83-

<PAGE>

sory Note shall be in a form mutually satisfactory to the
Stockholders' Agent and Buyer and shall have the typical
characteristics of an unsecured obligation of its kind and shall
be subject to acceleration of maturity on account of any default
thereunder and shall be subject to prepayment in whole at any
time or in part from time to time without penalty or premium of
any kind.

     6.28  SECTION 351 OF THE CODE.  Each of the Sellers and
Buyer agree to report, for federal and state income tax purposes,
the transfer of the Class A Common Stock, the Class B Common
Stock and the cash of Buyer in exchange for Buyer Common Stock,
Buyer Series A Preferred Stock and cash as a transaction governed
by Section 351 of the Code and agree to act in accordance
herewith (a) in the preparation of financial statements, (b) in
the filing of all tax returns and (c) except as otherwise
required by law, during the course of any tax audit, tax review
or tax litigation relating thereto.  The parties hereto
acknowledge that references to purchase and sale of the Class A
and Class B Common Stock are for the convenience of the parties
and are not intended to effect treatment of the transaction under
the Code.

     6.29  LEASE OF CERTAIN ASSETS.  The Buyer agrees that it
will enter into an operating lease with each of the Operating
Subsidiaries concurrently with the First Closing pursuant to
which the Operating Subsidiaries will be permitted to use the

                               -84-

<PAGE>

Assets and the S&J Assets in the operation of their businesses.
The parties agree that the lease will be solely for the Buyer's
benefit and lease payments thereunder shall be based on the fair
market value and the term shall be for at least one year.

     9.2  INDEMNIFICATION BY THE STOCKHOLDERS.  Subject to the
limitations set forth in this Article IX, the Stockholders shall
indemnify Buyer and its affiliates, officers, directors,
employees, agents, successors and assigns for, and shall defend
and hold them harmless from, against and with respect to all
loss, liability, damage (including exemplary damage) and expense
(including, without limitation, reasonable attorneys' fees and
costs and expenses reasonably incurred in investigating any
claim, but excluding those losses, liabilities, damages or
expenses covered by insurance) (collectively, "Damages") that
result from:

          (a)  any breach of or noncompliance with any of
Sellers' representations, warranties, covenants or agreements
contained in this Agreement or in the certificate referred to in
Section 7.2(c) hereof, other than representations and warranties
contained in Section 4.12 hereof; and any environmental
remediation of any real property acquired by Buyer or a
subsidiary of Buyer at the First Closing, or owned or leased by
the Company or any of its Subsidiaries at the time of the Second
Closing, to correct conditions existing prior to the First

                               -96-

<PAGE>

Closing with respect to such property (i) to the extent
correction is required by Environmental Laws, unless (ii) such
correction is required solely to enable such property to be used
for the purpose used prior to the First Closing in compliance
with Environmental Laws; in which case, any remediation required
under this clause (ii) shall be included in the calculation of
Damages only if such remediation is reasonable from an economic
standpoint (determined by weighing the cost of the remediation
against the value of the property to the ongoing business); and
provided, further, that the Stockholders shall have no liability
for amounts otherwise indemnifiable under this paragraph (a)
until the total of such amounts exceed $700,000 plus the Tank
Overage Amount, if any, and then only to the extent that the
total of such amounts exceed $700,000 plus the Tank Overage
Amount, if any; and provided, further, that any amount payable to
Buyer under this paragraph (a) shall be payable solely out of the
Contract Escrow Funds and that the Stockholders' liability for
such indemnification shall not exceed the Contract Escrow Funds;
provided, however, that $4 million of the Contract Escrow Cash
shall be allocated solely to settle Claims for Damages with
respect to a breach of the representations and warranties in
Section 4.9(a) hereof with respect to ownership of consumer
propane tanks, and any amount remaining after 180 days after the
Second Closing and not in dispute with respect to such Claims

                               -97-

<PAGE>

shall be available to provide the Stockholders with a source to
fund the payment of Damages relating to the C&L Matters; or

          (b)  any breach of the representations and warranties
set forth in Section 4.12 hereof; provided, however, that the
Stockholders shall have no liability for amounts otherwise
indemnifiable for a breach of their representations and
warranties under this paragraph (b) until the total of such
amounts exceed $250,000, and then only to the extent that the
total of such amounts exceeds $250,000; provided, further, that
if a claim is indemnifiable under paragraph (a) above, it shall
not be indemnifiable under this paragraph (b).

          (c)  Notwithstanding the foregoing, (i) no claim shall
be asserted pursuant to Sections 9.2(a) or 9.2(b) hereof with
respect to any liability included in calculating the Statement
Working Capital pursuant to Section 1.6 hereof or if such claim
is a C&L Matter; (ii) no claim shall be asserted pursuant to
Section 9.2(b) hereof until the aggregate amount of such claims
exceeds the aggregate amount of any Tax Refunds (as defined
below); and (iii) no claim shall be asserted pursuant to Section
9.2(b) hereof until an amount equal to the lesser of (A) the
total amounts of the Company's and its Subsidiaries' net
operating losses as of the First Closing Date in excess of the
amounts applied to reduce their taxable gains on the sale of the
Assets to Buyer after giving effect to the purchase by the

                               -98-

<PAGE>

Company of the Series B Notes at the First Closing and (B)
$1,000,000 is applied to offset any increase in taxable income
for federal income tax purposes resulting from such Claim.  A
"Tax Refund" shall mean any refund or recovery of Taxes with
respect to any period ending on or prior to the Second Closing
Date received by the Company and its Subsidiaries after the
Second Closing Date.

     9.3  INDEMNIFICATION BY BUYER.  Subject to the limitations
set forth in this Article IX, Buyer and NGC shall indemnify the
Stockholders and their respective affiliates, officers,
directors, employees, agents, successors and assigns, for, and
shall defend and hold them harmless from, against and with
respect to any Damages that result from any breach of or
noncompliance with any of Buyers' or NGC's representations,
warranties, covenants or agreements contained in this Agreement
or in the certificate referred to in Section 7.1(c) hereof.

     9.4  GENERAL PROCEDURES.  (a)  Notice.  A party that may be
entitled to indemnification under this Article IX (an
"Indemnified Person") shall give written notice to the other
party (the "Indemnifying Person") of the assertion of any claim,
or the commencement or any suit, action or proceeding, which such
party discovers or of which it receives notice which might give
rise to a claim under this Article IX ("Claim"). Such notice
shall specify (i) that a Claim is being made; (ii) the section or

                               -99-

<PAGE>

sections of this Agreement under which such Claim is made; (iii)
in reasonable detail, to the extent known, each individual item
of Damages and the basis therefor, and all items which offset any
Claim, and (iv) all items which in the aggregate comprise the
deductible (required until such deductible has been met).  With
respect to a Claim pursuant to Section 9.2(a) hereof, all notices
shall be delivered contemporaneously to the Contract Escrow
Agent.

          (b)  Third Party Claims.  The obligations and
liabilities of the Indemnifying Person under this Article IX with
respect to Damages arising from Claims of any third party which
are subject to the indemnification provided for in this Article
IX and except as otherwise provided in Section 6.10(c) hereof
("Third Party Claims") shall be governed by and contingent upon
the following additional terms and conditions:  if an Indemnified
Person shall receive notice of any Third Party Claim, the
Indemnified Person shall give the Indemnifying Person notice of
such Third Party Claim within 30 days of the receipt by the
Indemnified Person of such notice; provided, however, that the
failure to provide such notice shall not release the Indemnifying
Person from any of its obligations under this Article IX except
to the extent the Indemnifying Person is prejudiced by such
failure and shall not relieve the Indemnifying Person from any
other obligation or liability that it may have to any Indemnified
Person

                              -100-

<PAGE>

other than under this Article IX.  The Indemnifying Person shall
be entitled to assume and control the defense of such Third Party
Claim at its expense and through counsel of its choice if it
gives notice of its intention to do so to the Indemnified Person
within five days of the receipt of such notice from the
Indemnified Person; provided, however, that if there exists,
under applicable standards of professional conduct, a conflict
between the positions of such parties on any significant issue
that would make it inappropriate in the judgment of the
Indemnified Person, in its sole discretion, for the same counsel
to represent both the Indemnified Person and the Indemnifying
Person, then the Indemnified Person shall be entitled to retain
its own counsel at the Indemnifying Person's sole expense.  In
the event the Indemnifying Person exercises the right to
undertake any such defense against any such Third Party Claim as
provided above, the Indemnified Person shall cooperate with the
Indemnifying Person in such defense and make available to the
Indemnifying Person, at the Indemnifying Person's expense, all
witnesses, pertinent records, materials and information in the
Indemnified Person's possession or under the Indemnified Person's
control relating thereto as is reasonably required by the
Indemnifying Person.  Similarly, in the event the Indemnified
Person is, directly or indirectly, conducting the defense against
any such Third Party Claim, the Indemnifying Person shall
cooperate with the Indemni-

                              -101-

<PAGE>

fied Person in such defense and make available to the Indemnified
Person, at the Indemnified Person's expense, all such witnesses,
records, materials and information in the Indemnifying Person's
possession or under the Indemnifying Person's control relating
thereto as is reasonably required by the Indemnified Person.  No
such Third Party Claim may be settled by the Indemnifying Person
without the prior written consent of the Indemnified Person
(which consent shall not be unreasonably withheld if the
Indemnified Person would not be unduly prejudiced); except that a
Third Party Claim which does not involve allegations of criminal
or fraudulent conduct by the Indemnified Person and seeks only
non-exemplary damages against the Indemnified Person may be
settled by the Indemnifying Person if such settlement involves a
complete release of the Indemnified Person from liability.

          (c)  CLAIMS DISPUTE RESOLUTION.  Upon receipt by an
Indemnifying Person of a notice of a Claim pursuant to Section
9.4(a), if the Indemnifying Person disagrees with the Claim or
the amount of Damages claimed, the Indemnifying Person shall
notify the Indemnified Person and the Contract Escrow Agent in
writing within 30 days after the Indemnifying Person's receipt
of such notice of Claim, and the Indemnifying Person and the
Indemnified Person shall attempt to resolve such disagreement.
If the Indemnifying Person does not notify the Indemnified
Person in writing of its disagreement with such notice of Claim
within 30

                           -102-
<PAGE>

days of receipt of such notice of Claim, Damages shall be the
amount set forth in such notice of Claim.  If such parties are
unable to resolve such disagreement within 30 days after the
receipt by the Indemnified Person of the Indemnifying Person's
written disagreement with such Claim, then such parties shall
submit such dispute to binding arbitration in accordance with
the terms of this Agreement.

     9.5  STOCKHOLDERS' AGENT.  At all times after the date of
this Agreement until all the Stockholders' obligations under this
Agreement have been satisfied or expired, the Stockholders shall
have one or more persons duly appointed and authorized to act as
their attorney in fact with respect to all matters relating to
this Agreement and the transactions contemplated herein (the
"Agreement Matters"; the person or persons so appointed and
authorized to so act at any given time being referred to herein
as the "Stockholders' Agent").  Each of the Stockholders hereby
appoints Stephen A. Vogel as the Stockholders' Agent, and
authorizes him to act as his or her attorney in fact with respect
to all Agreement Matters (including receiving notice for
indemnification purposes).  Any and all parties to this Agreement
shall be entitled to rely, and shall be fully protected in
relying, upon as fully binding upon all of the Stockholders, all
action taken by the Stockholders' Agent, including any instrument
or document executed in each of the Stockholders' names by the
Stockholders'

                              -103-

<PAGE>

Agent, prior to receiving notice of a successor being appointed
by the Stockholders to the person who took such action as the
Stockholder's Agent.  The Stockholders' Agent shall not be liable
to the Stockholders for any action taken or omitted by him in
good faith and believed by him to be authorized hereby or within
the rights or power conferred upon him hereunder, nor for action
taken or omitted by him in good faith, nor for any mistake of
fact or error of judgment or for any acts or omissions of any
kind unless caused by willful misconduct or gross negligence.

     9.6  INDEMNIFICATION OBLIGATIONS.  Each of the Stockholders'
indemnification obligations under Article IX and Article X of
this Agreement shall be several and not joint; except, that with
respect to the indemnification obligations of Sherman C. Vogel
and Jeanette Vogel, such indemnification obligations shall be
joint and several as to each other.

X.  C&L MATTERS

     10.1  C&L MATTERS.  Subject to the limitations set forth in
this Article X, the Stockholders shall indemnify Buyer and its
affiliates, officers, directors, employees, agents, successors
and assigns (each a "C&L Indemnified Person") for, and shall
defend and hold them harmless from, against and with respect to
all Damages that result from any claim, suit, action and other
proceeding by or before any court or governmental authority

                              -104-

<PAGE>

(each, a "Proceeding") arising out of, or relating to, the
operations of the Company and its Subsidiaries, and the condition
of their respective properties, up to and but not including the
Second Closing Date (the "C&L Period"), whenever asserted
(whether before or after the Second Closing Date), other than
those matters covered in Sections 4.9, 4.12 and 4.16 hereof and
their corresponding Sections of the Disclosure Schedule
(collectively, the "C&L Matters" and individually a "C&L
Matter"); provided, however that, with respect to a Proceeding
brought after the Second Closing Date, in order for such
Proceeding to be deemed a C&L Matter such Proceeding (i) must
have been commenced by the earlier of the third anniversary of
the Second Closing Date and the expiration of the statute of
limitations for such Proceeding, in the case of a Proceeding for
wrongful death, personal injury or property damage, and (ii) must
have been commenced by the first anniversary of the Second
Closing Date, in the case of all other Proceedings; provided
further, that, 180 days after the Second Closing Date, the $4
million of the Contract Escrow Cash allocated to cover Damages
for a breach of the consumer propane tank ownership
representation and warranty in Section 4.9(a) hereof, less (a)
any Damages paid for a breach of such tank ownership
representation and warranty, and (b) any amount in dispute with
respect to a claim for such Damages for a breach of such tank
representation and warranty, shall be available to

                              -105-

<PAGE>

provide the Stockholders with a source to fund the payment of
Damages relating to the C&L Matters.

     10.2  ADJUSTMENTS TO THE C&L MATTERS ESCROW FUNDS.

          (a)  Upon the termination of the Contract Escrow
Agreement, the Contract Escrow Agent shall deliver to the C&L
Matters Escrow Agent any remaining shares of Buyer Series A
Preferred Stock.  Such stock shall be endorsed to the C&L Matters
Escrow Agent and at such time shall be included in the term "C&L
Matters Escrow Fund".

     (b)  Buyer shall hire, or shall cause the Company to hire, a
firm to determine an appropriate litigation reserve for the
outstanding C&L Matters on the second and third anniversaries of
the Second Closing Date.  Such determinations shall be delivered
by such firm directly to Buyer, the Stockholders' Agent and the
C&L Matters Escrow Agent.  The selected firm shall be mutually
agreed to by Buyer and the Stockholders' Agent and shall be in
the business of performing such types of determinations.  The
cost of such firm for the two determinations referred to above
shall be borne equally by Buyer and the Stockholders.  The
Stockholders shall have the right to hire a firm (that has been
approved in writing by Buyer) at their sole cost to perform
determinations in addition to the two determinations referred to
above at any time after such first determination is performed.
To the extent such firm's determination of the appropriate

                              -106-

<PAGE>

reserve is less than the C&L Matters Escrow Cash at the time of
such determination, such excess cash shall be released from
escrow by the C&L Matters Escrow Agent and delivered to the
Stockholders' Agent.

     10.3  C&L MATTERS GOVERNANCE.

          (a)  When the Company or any of its affiliates receives
notice of the assertion of any C&L Matter, Buyer shall give the
Stockholders' Agent notice thereof not later than five business
days (but sooner, subject to Buyer's best efforts, to the extent
a temporary restraining order is involved) of the receipt by the
Company or any of its affiliates of such notice of assertion and
Buyer shall forward, or cause to be forwarded, to the
Stockholders' Agent all documents received by it or Buyer's
affiliates with respect to C&L Matters within five business days
after receipt of such documents; provided, however, that the
failure to provide such notice or other documents to the
Stockholders' Agent shall not release the Stockholders from any
of their obligations under this Article X except to the extent
the Stockholders are prejudiced by such failure and shall not
relieve the Stockholders from any other obligation or liability
that they may have to any of the Indemnified Persons other than
under this Article X.  The Stockholders shall assume and control
the defense of each such C&L Matter and shall pay all Damages
relating to such C&L Matter.  The Company and its affiliates

                              -107-

<PAGE>

shall cooperate with the Stockholders in the defense of the C&L
Matters and make available to the Stockholders, all personnel,
witnesses, pertinent records, materials and information in the
Company's or its affiliates' possession or under such person's
control relating thereto as is reasonably required by the
Stockholders.  No C&L Matter may be settled by the Stockholders
without the prior written consent of Buyer (which consent shall
not be unreasonably withheld if the Company and its affiliates
would not be unduly prejudiced); except that a C&L Matter which
does not involve allegations of criminal or fraudulent conduct by
the Company and its affiliates and seeks only non-exemplary
damages against some or all of the named defendants may be
settled by the Stockholders if such settlement involves a
complete release of such defendants from liability.

          (b)  A C&L Indemnified Person shall give written notice
to the Stockholders' Agent, on behalf of the Stockholders, (the
"C&L Indemnifying Person") of the assertion of Damages under this
Article X.  Such notice shall specify (i) that a claim is being
made for Damages that have not been paid by the Stockholders
pursuant to this Article X, and (ii) in reasonable detail, to the
extent known, each individual item of Damages and the basis
therefor.  With respect to a claim pursuant to this Article X,
all notices shall be delivered contemporaneously to the C&L
Matters Escrow Agent.

                              -108-

<PAGE>

          (c)  Upon receipt by a C&L Indemnifying Person of a
notice of a claim for Damages pursuant to Article X, if the C&L
Indemnifying Person disagrees with the claim or the amount of
Damages claimed, the Indemnifying Person shall notify the C&L
Indemnified Person and the C&L Matters Escrow Agent in writing
within 30 days after the C&L Indemnifying Person's receipt of
such notice of claim, and the C&L Indemnifying Person and the C&L
Indemnified Person shall attempt to resolve such disagreement.
If the C&L Indemnifying Person does not notify the C&L
Indemnified Person in writing of its disagreement with such
notice of claim within 30 days of receipt of such notice of
claim, Damages shall be the amount set forth in such notice of
claim.  If such parties are unable to resolve such disagreement
within 30 days after the receipt by the C&L Indemnified Person of
the C&L Indemnifying Person's written disagreement with such
claim, then such parties shall submit such dispute to binding
arbitration in accordance with the terms of this Agreement.

          (d)  With respect to all C&L Matters, the Stockholders
shall be subrogated to all rights of the Company and its
affiliates with respect to all third parties relating to C&L
Matters.  Buyer shall cause the Company to maintain appropriate
insurance for the Company's business as determined in Buyer's
sole discretion.  In the event that Buyer or the Company
determines to terminate any insurance policy set forth in Section
4.20 of the

                              -109-

<PAGE>

Disclosure Schedule which covers C&L Matters, the Stockholders'
Agent shall have the right at its sole expense, to continue such
policies.  Buyer shall provide the Stockholders' Agent with 30
days written notice of any such proposed termination.

XI.  MISCELLANEOUS

               11.1  FEES AND EXPENSES.  Whether or not the transactions
contemplated by this Agreement are consummated, Buyer shall pay
all fees and expenses incurred by (or on behalf of) Buyer, NGC,
or their respective affiliates, and the Stockholders shall pay
all fees and expenses incurred by (or on behalf of) the
Stockholders, the Company or their respective affiliates, in
connection with, or in anticipation of, this Agreement and the
consummation of the transactions contemplated hereby.

     11.2  FURTHER ASSURANCES.  From time to time after the
Second Closing Date, at the request of Sellers and S&J on the one

case may be, shall execute and deliver to such requesting party
such documents and take such other action as such requesting

<PAGE>

sions shall remain in full force and effect and the application

of which collectively shall constitute one and the same
instrument.

     11.9  INTERPRETATION.  (a)  The article and section headings
contained in this Agreement are solely for the purpose of

                 AGREEMENT AMONG SYN INC. AND ITS STOCKHOLDERS


            THIS AGREEMENT, dated ___________ _____, 1995, is made and entered
into by and among SYN Inc., a Delaware corporation (the "Company"), Northwestern
Growth Corporation, a South Dakota corporation ("NGC"), Empire Gas Corporation,
a Missouri corporation (Empire"), and the persons hereinafter sometimes called
the "Vogels," namely, Sherman C. Vogel, Stephen A. Vogel, Jeffrey K. Vogel, Jon
M. Vogel and Jeannette Vogel (NGC, Empire and the Vogels being hereinafter
sometimes collectively called the "Stockholders" and individually called a
"Stockholder"), with respect to the following circumstances:

      A.    The Company has been incorporated for the purposes of entering into
the Purchase and Sale Agreement, dated May 17, 1995, by and among the Vogels,
Synergy Group Incorporated ("Synergy"), S&J Investments, the Company and NGC
(the "Synergy Agreement"), consummating the closing thereunder by which the
Company and its subsidiaries are to acquire substantially all of the business
and various assets of, and stock interests in, Synergy and its subsidiaries (the
"Synergy Acquisition"), and operating the acquired business on an ongoing basis.

      B.    NGC owns beneficially and of record 82,500 of the 100,000 authorized
shares of Common Stock of the Company, par value $.01 per share (the "Common
Stock").

      C.    The Vogels, as part of the consideration for the Synergy
Acquisition, have been issued, and own beneficially and of record, the remaining
17,500 shares of the authorized shares of Common Stock (which will be 17.5% of
the issued and outstanding Common Stock before and after the exercise of the
Empire Option (defined in paragraph D below)), as follows:

                                                NUMBER OF SHARES
                                                ----------------
                  Sherman C. Vogel
                  Stephen A. Vogel
                  Jeffrey K. Vogel
                  Jon M. Vogel
                  Jeannette Vogel

      D.    Empire has an option to acquire from NGC up to 30,000 of the shares
of Common Stock owned by NGC (such 30,000 shares constituting 30% of the issued
and outstanding Common Stock), as provided in the Agreement Among Initial
Stockholders and SYN Inc., dated May 17, 1995, among the Company, NGC and Empire
(the "Empire Option").

      E.    The parties hereto are entering into this Agreement pursuant to the
Synergy Agreement and to satisfy an essential condition to the Vogels'
acceptance of the 17,500 shares of Common Stock as part of the consideration for
the Synergy Acquisition.

            NOW THEREFORE, in consideration of the foregoing premises and the
agreements herein, the parties hereto agree as follows:



<PAGE>



                       ARTICLE 1:  REGISTRATION RIGHTS

      SECTION 1.01  DEFINITIONS.  For purposes of this Agreement:  (i) the term
"1933 Act" means the Federal Securities Act of 1933, as amended; (ii) the terms
"register," "registered" and "registration" refer to a registration effected by
filing a registration statement in compliance with the 1933 Act (a "registration
statement") and such registration statement becoming effective under the 1933
Act; (iii) the term "Registrable Securities" means the outstanding shares of
Common Stock of the Company held by the Stockholders from time to time or any
securities issued in exchange therefor in the event of a recapitalization, stock
split, merger, consolidation or other combination or exchange of shares; and
(iv) the term "Holder" means any Stockholder who owns of record Registrable
Securities.

      SECTION 1.02  COMPANY REGISTRATION.  Subject to Section 1.06 hereof, if
at any time the Company determines to register any shares of Common Stock under
the 1933 Act in connection with the public offering of such securities solely
for cash on a form that would also permit the registration for public
distribution of any of the Registrable Securities, the Company shall, each such
time, promptly give each Holder written notice of such determination.  Upon the
written request of any Holder received by the Company within 30 days after the
giving of any such notice by the Company to such Holder, the Company shall use
its best efforts to cause to be registered under the 1933 Act all of the
Registrable Securities that each such Holder has requested be registered,
together with the registration of the Common Stock otherwise being registered by
the Company.  The Company may elect to either not file or withdraw the filing of
any registration statement relating to a registration described in this Section
1.02 at any time prior to the effectiveness thereof.

     SECTION 1.03  OBLIGATIONS OF THE COMPANY.  Whenever under Section 1.02 or
1.08 hereof the Company is to use its best efforts to effect the registration of
any Registrable Securities, that shall require the Company to do the following:

            (a)   As expeditiously as reasonably possible, prepare and file with
      the Securities and Exchange Commission ("SEC," which term includes any
      successor agency) a registration statement with respect to such
      Registrable Securities, together with the Common Stock otherwise being
      registered by the Company, and use its best efforts to cause such
      registration statement to become and remain effective under the 1933 Act,
      except that the Company shall in no event be obligated to cause any such
      registration to remain effective for more than nine months.

            (b)   As expeditiously as reasonably possible, prepare and file with
      the SEC such amendments and supplements to such registration statement and
      the prospectus used in connection with such registration statement as may
      be necessary to comply with the provisions of the 1933 Act with respect to
      the disposition of all securities covered by such registration statement.

            (c)   As expeditiously as reasonably possible, furnish to the
      Holders such numbers of the copies of the prospectus used in connection
      with such registration statement (including all preliminary prospectuses
      and the final prospectus), and all amendments and supplements thereto, and
      such other documents as they may reasonably request in order to facilitate
      the distribution of the Registrable Securities owned by them.



                                        2
<PAGE>



            (d)   As expeditiously as reasonably possible, make a commercially
      reasonable effort to register and qualify the securities covered by such
      registration statement under such securities or Blue Sky laws of such
      jurisdictions as shall be reasonably appropriate or requested by the
      Holders or by the underwriter for the distribution of the securities
      covered by the registration statement, except that the Company shall not
      be required in connection therewith or as a condition thereto to qualify
      to do business or to file a general consent to service of process  in any
      such jurisdiction, and except that (anything in this Agreement to the
      contrary notwithstanding with respect to the bearing of expenses) if any
      jurisdiction in which the securities shall be qualified shall require that
      expenses incurred in connection with the registration or qualification of
      the securities in that jurisdiction be borne by those selling the
      securities, then such expenses shall be payable by selling Holders pro
      rata, to the extent required by such jurisdiction.

            (e)   Advise each Holder promptly after the Company shall receive
      notice or obtain knowledge thereof of (i) the issuance of any stop order
      by the SEC suspending the effectiveness of such registration statement or
      the initiation or threatening of any proceeding for that purpose, (ii) any
      similar action by any regulatory agency of competent jurisdiction under
      the securities or Blue Sky laws of any jurisdiction, and in any such case
      promptly make a commercially reasonable effort to prevent the issuance of
      any stop order or the taking of any such similar action or to obtain its
      withdrawal if such stop order shall be issued or any such similar action
      shall be taken, and (iii) the happening of any event as a result of which
      the prospectus included in such registration statement contains an untrue
      statement of material fact or omits to state any fact necessary to make
      the statements therein not misleading.

            (f)   Furnish to each Holder of Registrable Securities covered by
      such registration statement copies of all documents proposed to be filed
      with respect to any amendment or supplement to such registration statement
      or prospectus at a reasonable time prior to such filing, and not file any
      such amendment or supplement to which the Holders of a majority of the
      Registrable Securities covered by such registration statement shall have
      reasonably objected on the grounds that such amendment or supplement does
      not comply in all material respects with the requirements of the 1933 Act
      or the rules and regulations thereunder, unless in the opinion of counsel
      for the Company the filing of such amendment or supplement is reasonably
      necessary to protect the Company from any liabilities under any applicable
      federal or state law and such filing will not violate applicable law.

            (g)   Furnish on the effective date of the registration statement
      and, if such registration includes an underwritten public offering, at the
      closing provided for in the underwriting agreement:  (i) an opinion, dated
      each such date, of the counsel representing the Company for the purposes
      of such registration, addressed to the underwriters, if any, and to the
      Holders participating in such registration, stating that such registration
      statement has become effective under the 1933 Act and that (A) to the best
      of such counsel's knowledge, no stop order suspending the effectiveness
      thereof has been issued and no proceedings for that purpose have been
      instituted or are pending or contemplated under the 1933 Act, (B) the
      registration statement, related prospectus and each amendment or
      supplement thereto comply as to form in all material respects with the
      requirements of the 1933 Act and the applicable rules and regulations of
      the SEC thereunder (except that such counsel need express no opinion as to
      financial statements and financial data contained


                                        3
<PAGE>



      therein), (C) such counsel have no reason to believe that the registration
      statement, the prospectus or any amendment or supplement thereto contains
      any untrue statement of a material fact or omits to state a material fact
      required to be stated therein or necessary to make the statements therein,
      in the light of circumstances under which they were made, not misleading
      (except that such counsel need express no belief as to the financial
      statements and financial data contained therein), (D) the description in
      the registration statement or prospectus or any amendment or supplement
      thereto of all legal and governmental proceedings and all contracts and
      other legal documents or instruments filed as exhibits to the registration
      statement are accurate and fairly present the information required to be
      shown, and (ii) a letter dated each such date, from the independent
      certified public accountants of the Company, addressed to the
      underwriters, if any, and to the Holders participating in such
      registration, covering such matters as such underwriters and such Holders
      may reasonably request, in which letter such accountants shall state
      (without limiting the generality of the foregoing) that they are
      independent certified public accountants within the meaning of  the 1933
      Act and that in the opinion of such accountants the financial statements
      and other financial data of the Company included in the registration
      statement or the prospectus or any amendment or supplement thereto comply
      in all material respects with the applicable accounting requirements of
      the 1933 Act and applicable rules and regulations thereunder.

            (h)   Enter into such customary agreements and take all such other
      actions as the holders of a majority of the Registrable Securities covered
      by such registration statement or the managing underwriters for such
      registration may reasonably request in order to facilitate the
      distribution of such Registrable Securities (including, without
      limitation, to cause such Registrable Securities to be listed on such
      securities exchange on which similar securities issued by the Company are
      then listed, to cause such Registrable Securities to be eligible for
      quotation and transaction reporting through an automated inter-dealer
      quotation system operated by a national securities association, and to
      provide a transfer agent and registrar).

            (i)   Make available for inspection by, and cause the Company's
      officers, directors, employees and independent accountants to supply to,
      any Holder of Registrable Securities covered by such registration
      statement, any underwriter participating in the distribution pursuant to
      such registration statement, and any attorney, accountant or other agent
      for any thereof, all financial and other records of the Company and all
      information reasonable requested in connection with such registration
      statement.

      SECTION 1.04  FURNISH INFORMATION.  It shall be a condition precedent to
the obligations of the Company to take any action pursuant to this Article 1
that the Holders shall furnish to the Company such information regarding
themselves, the Registrable Securities held by them, and the intended method of
disposition of such securities as the Company shall reasonably request and as
shall be required in connection with the action to be taken by the Company.

      SECTION 1.05  EXPENSES OF REGISTRATION.  All expenses incurred in
connection with a registration pursuant to Section 1.02 hereof (excluding
underwriters' discounts and commissions and expenses expressly required by
Section 1.03(d) hereof to be paid by the selling Holders), including without
limitation all registration and qualification fees, printers' and accounting
fees, fees and


                                        4
<PAGE>



disbursements of counsel for the Company, internal expenses of the Company
(including, without limitation, salaries of officers and employees) and listing
fees shall be borne by the Company.

      SECTION 1.06  UNDERWRITING REQUIREMENTS.  In connection with any
registration requested by any Holder pursuant to Section 1.02 hereof, the
Company shall not be required hereunder to include any of the Holders'
Registrable Securities in such registration unless the Holders accept the terms
of the underwriting as agreed upon between the Company and the underwriters
selected by it, and then only in such quantity as will not, when added to the
securities otherwise being registered by the Company, in the written opinion of
the managing underwriters, exceed the Maximum Feasible Quantity for such
registration.  If the total number of Registrable Securities requested pursuant
to this Agreement to be included in such registration, when added to the
securities otherwise being registered by the Company, exceeds the Maximum
Feasible Quantity for such registration, then the Registrable Securities of the
Holders to be included in such registration shall be apportioned among the
selling Holders, based on the total number of Registrable Securities requested
to be registered by each.  All shares sold to cover any over-allotment shall be
apportioned among the selling Holders and the Company in proportion to the total
number of shares being sold by each; provided, however, that any such
over-allotment shall first be allocated to the selling Holders to the extent any
of the Registrable Securities requested to be included in such registration by
all Holders, when added to the securities otherwise being registered by the
Company, exceeded the Maximum Feasible Quantity. For purposes of this Agreement,
Maximum Feasible Quantity shall be the amount of securities which the managing
underwriter for the underwritten public offering of the Common Stock reasonably
believes to be the maximum number that should be included in the public offering
because the inclusion of shares in excess of such maximum number would likely
have a material adverse effect on the offering.

     SECTION 1.07  HOLDBACK AGREEMENT.

            (a)   Each Stockholder agrees not to effect any public sale or
      distribution of any equity securities of the Company, or any securities
      convertible into or exchangeable for any equity securities of the Company,
      during the 30 days prior to and the 90-day period beginning on the
      effective date of the registration of the Registrable Securities pursuant
      to Section 1.02 hereof, except, in either case, as a part of such
      underwritten public offering covered by such registration statement,
      unless the managing underwriters for such offering otherwise agree.

            (b)   The Company agrees not to effect any public sale or
      distribution of any of its equity securities, or any securities
      convertible into or exchangeable for any of its equity securities, during
      the 30 days prior to and the 90-day period beginning on the effective date
      of the registration of Registrable Securities pursuant to Section 1.02
      hereof (except, in either case, pursuant to a registration on Form S-8 or
      a similar successor form), unless the managing underwriters for the public
      offering pursuant to Section 1.02 hereof otherwise agree that such public
      sale or distribution will not adversely affect the public offering
      pursuant to Section 1.02 hereof.

      SECTION 1.08  REQUEST FOR REGISTRATION.  If, after the Company has
concluded the sale of shares of Common Stock in an initial underwritten public
offering thereof for which the shares were registered under the 1933 Act, and
while this Agreement remains in effect, any one of the Vogels gives written
notice to the Company (specifying that it is being given pursuant to this
Section 1.08)


                                        5
<PAGE>



requesting the Company to file a registration statement to register under the
1933 Act a specified amount of Registrable Securities owned by the requesting
person, then the Company shall promptly notify all of the other Vogels who are
Holders of such request.  Within 30 days after receipt by such other Vogels of
notice of such request, each of them may notify the Company that as such a
Holder he or she requests that all or a portion of such Holder's Registerable
Securities be included in such registration (all of the Vogels who at that point
have requested the Company to include some or all of their Registrable
Securities in the registration being hereinafter referred to as the "Sellers").
The Company shall then use its best efforts to cause to be registered under the
1933 Act all Registrable Securities that the Sellers have so requested to be
registered.  Notwithstanding the foregoing, the Company shall not be obligated
to effect a registration pursuant to this Section 1.08 during the period
starting with the date forty-five (45) days prior to the Company's estimated
date of filing of, a registration statement pertaining to an underwritten public
offering of Common Stock for the account of the Company, provided that the
Company is actively employing in good faith all reasonable efforts to cause such
registration statement to become effective and that the Company's estimate of
the date of filing such registration statement is made in good faith.  The
Company shall be obligated to effect one registration pursuant to this Section
1.08.  Any request for registration under this Section 1.08 must be for a firm
underwritten public offering in accordance with terms agreed upon between the
underwriter or underwriters and the Holders of a majority of the Registrable
Securities being sold for the Sellers under the registration, to be managed by
an underwriter or underwriters of recognized national standing designated by the
Sellers and reasonably acceptable to the Company.  At any time prior to the
effectiveness of the registration statement, any request for registration under
this Section 1.08 may be withdrawn by the Sellers, whereupon the Company shall
either not file or withdraw the filing of the registration statement, as
applicable, and such withdrawal of the request for registration will not be
deemed to have been the exercise of the registration right granted in this
Section 1.08.  The provisions of Sections 1.03, 1.04 and 1.05 herein shall apply
to any registration, or attempts to effect registration, which the Company is
required to make under this Section 1.08, including any registration statement
that is withdrawn or not filed as provided in this Section 1.08, except that the
expenses which the Company would otherwise be required to bear under Section
1.05 herein shall be paid in equal shares by the Company as one party and by the
Sellers as the other party.


                    ARTICLE 2:  RESTRICTIONS ON TRANSFER

      SECTION 2.01  GENERAL RESTRICTIONS.  Each Stockholder agrees not to
sell, transfer, pledge or otherwise dispose of any of the Stockholder's shares
of Common Stock except in a transaction for which the shares have been
registered under the 1933 Act, or in a transaction which is exempt from such
registration under the 1933 Act.  Without limiting the Vogels' rights under the
preceding sentence, in each case in which any of the Vogels transfers his or her
shares of Common Stock to his or her parents, siblings, descendants and/or
descendants of siblings, or to a trust for the benefit of any of them, and such
transferee joins in this Agreement as a Stockholder (which it is agreed that
each such transferee may do), then such transferee shall thereupon be deemed to
be included in the term "Vogels," and thereafter will be one of the Vogels for
all purposes of this Agreement.

      SECTION 2.02  PARALLEL EXIT.

            (a)   No Stockholder, alone or in connection with any other
      Stockholders, in a single transaction or series of related transactions,
      shall directly or indirectly sell, transfer


                                        6
<PAGE>



      or otherwise dispose of, shares of Common Stock which in the aggregate
      entitle the holder thereof to cast a majority of the votes entitled to be
      cast for the election of directors of the Company in a general election of
      such directors, unless (i) prior to such sale, transfer or other
      disposition each of the Stockholders (other than those proposing such
      sale, transfer or other disposition, who are hereinafter referred to as
      the "Selling Stockholders") has been notified of the proposed transaction
      and has been provided a firm, irrevocable right, exercisable within 30
      days after the date such notice is given to the Stockholders, to sell to
      the proposed transferee at the same time and upon the same terms and
      conditions offered to the Selling Stockholders that percentage of the
      shares of Common Stock then owned by such Stockholder as is at least equal
      to the percentage of the total shares of Common Stock owned by the Selling
      Stockholders which are proposed to be sold, transferred or otherwise
      disposed of by the Selling Stockholders in such transaction, and (ii) the
      transferee in such transaction enters into a binding assumption agreement
      by which it assumes and agrees to be bound by all of the obligations of
      Stockholders under this Agreement with respect to the shares of Common
      Stock to be acquired by such transferee in such transaction.  For purposes
      of this Agreement, the sale, transfer or other disposition of any stock
      option, warrant, convertible security or other right entitling the holder
      thereof to acquire shares of Common Stock shall be deemed to be a sale,
      transfer or other disposition of the shares of Common Stock obtainable by
      the exercise thereof, whether or not exercisable at the time, and votes
      entitled to be cast in the election of directors of the Company shall be
      calculated as if all rights to acquire securities that would be entitled
      to vote in a general election of directors of the Company at the time
      outstanding, whether or not then exercisable, have been exercised so as to
      entitle the securities derived from such exercise to be voted in such
      election.

            (b)   Notwithstanding the provisions of Section 2.02(a) above, those
      provisions shall not apply to the following:

                  (i)   any transfer from NGC to Empire of shares of Common
            Stock pursuant to the exercise of the Empire Option or any
            retransfer thereof from Empire to NGC pursuant to Section 1.04 of
            the Agreement Among Initial Stockholders and SYN Inc., dated May 17,
            1995, among the Company, NGC and Empire;

                  (ii)  any disposition of shares of Common Stock in connection
            with any merger, consolidation or liquidation of the Company;

                  (iii) any transfer of shares of Common Stock from NGC to
            Northwestern Public Service Company ("NWPS"), or any successor to
            substantially all of the business and assets of NWPS, or to any
            wholly owned subsidiary of NWPS or such successor, provided that
            such transferee enters into a binding assumption agreement by which
            it assumes and agrees to be bound by the obligations of NGC under
            this Agreement;

                  (iv)  any sale of shares of Common Stock in an underwritten
            public offering for which such shares are registered under the 1933
            Act; or



                                        7
<PAGE>



                  (v)   any pledge or granting of a security interest in shares
            of Common Stock owned by NGC (or its transferee under clause (iii)
            above) to secure loan financing obtained by NWPS, NGC, or such
            transferee, or any sale thereof by foreclosure of such pledge or
            security interest, or any sale in lieu of such foreclosure.


                         ARTICLE 4:  BOARD MEETINGS

            So long as this Agreement remains in effect, or until the Vogels
have disposed of their Registrable Securities, whichever first occurs, a
representative of the Vogels (designated in writing in a notice to the Company)
shall be given the same notice as is given to the directors of the Company of
all regularly scheduled meetings of the Board of Directors of the Company
("Board") (which will be scheduled according to the needs of the business and
affairs of the Company, but which are presently expected to be held at least
quarterly), as well as all written information provided to such directors for
each such meeting, and shall be allowed to attend (in person or by telephone)
each such meeting.

                         ARTICLE 5:  PUTS AND CALLS

      SECTION 5.01  PUTS AND CALLS.  At all times after the seventh
anniversary of the Second Closing Date under the Synergy Agreement while this
Agreement remains in effect, each of the Vogels shall have a put right to sell
to the Company his or her Registrable Securities at a price equal to 90% of the
fair market value thereof, determined as provided in Section 5.02, provided the
Company has adequate liquidity to make that purchase (combining for this purpose
all of the Registrable Securities for which such put rights at the time have
been exercised), as reasonably determined by the Board; and the Company shall
have a call right to purchase all of the Vogels' Registrable Securities at a
price equal to 110% of the fair market value thereof, determined as provided in
Section 5.02 herein.  Such put and call rights may be exercised by the giving of
written notice thereof to the Company (in the case of a put right) or to the
Vogels (in the case of a call right).

      SECTION 5.02  APPRAISAL AND CLOSING PROCEDURE.  Promptly after the
exercise of a put or call right granted under Section 5.01 herein, the parties
involved in the put or call transaction shall attempt to reach agreement as to
the fair market value of the Registrable Securities to be sold and purchased
(which shall be the proportionate share of the fair market value of the Company
as a whole, determined on a private company basis, allocated to the securities
involved in the exercised put or call without any discount for minority
interests), but if such agreement is not reached within 30 days after such
notice of exercise is given, then the fair market value of the Registrable
Securities to be sold and purchased as aforesaid shall be determined by an
appraiser or investment banker with recognized expertise in such matters, agreed
upon by the parties involved or if they cannot agree upon such an appraiser or
investment banker within 30 days, then each of the parties (the Company on one
side and the Vogels involved in the exercised put or call on the other) shall
select such an appraiser or investment banker, and those selected shall select a
third such appraiser or investment banker to determine such value.  The fees and
expenses of each such appraiser and investment banker shall be borne in equal
shares by the Company on one side and the Vogels involved in the exercised put
or call on the other.  As soon as the fair market value of the Registrable
Securities involved in the exercised put or call is determined, the parties
shall promptly consummate the sale and purchase of the Registrable Securities by
the Company making a payment


                                        8
<PAGE>



in an amount equal to such fair market value of such Registrable Securities,
determined as aforesaid, in exchange for delivery of clear title to such
Registrable Securities.  In the event the Company sells shares of Common Stock
in an initial underwritten public offering of its Common Stock within nine
months after the Company exercises a call right to purchase granted under
Section 5.01 herein, the Company will, upon closing such sale of shares in such
initial underwritten public offering, pay to each of the Vogels the difference
(if any) between the price paid to him or her for the shares purchased from him
or her by the exercise of the call purchase right and (if greater) the price
that would have resulted if the initial price to the public in such public
offering had been the fair market value of the Registrable Securities purchased
by the exercise of the call.


                          ARTICLE 6:  MISCELLANEOUS

      SECTION 6.01  RESTRICTIVE LEGEND.  Each certificate issued by the

                            MANAGEMENT AGREEMENT


            THIS AGREEMENT, dated May 17, 1995, is made and entered into among
Empire Gas Corporation, a Missouri corporation ("Empire"), Northwestern Growth
Corporation, a South Dakota corporation ("NGC"), and SYN Inc., a Delaware
corporation ("SYN"), with respect to the following facts:

      A.    Empire, NGC and Syn have entered into that certain Agreement Among
Initial Stockholders and SYN Inc., dated May 17, 1995 (the "Stock Agreement"),
which, among other things, requires this Agreement to be made for the reasons
recited in the Stock Agreement (such recitals being incorporated herein by this
reference).

      B.    SYN and NGC, immediately following the execution of this Agreement,
will be entering into that certain Purchase and Sale Agreement, dated as of May
17, 1995, with Sherman C. Vogel, Stephen A. Vogel, Jeffrey K. Vogel, Jon M.
Vogel, Jeanette Vogel, Synergy Group Incorporated (with its subsidiaries,
"Synergy"), and S&J Investments (the "Synergy Acquisition Agreement"), providing
for the acquisition by SYN of Synergy (the "Synergy Acquisition").

      C.    This Agreement is essential to the ability of SYN to finance and
consummate the Synergy Acquisition, and to manage the assets and business to be
acquired by the Synergy Acquisition.

            NOW, THEREFORE, in consideration of the premises and the agreements
exchanged herein, the parties hereto agree as follows:


                 ARTICLE 1:  ENGAGEMENT TO PLAN AND MANAGE

            SYN, on behalf of itself and its subsidiaries, and for the benefit
of its stockholders (of which NGC is a principal one), hereby engages Empire to
perform the planning and management of the assets and business operations of SYN
and its subsidiaries (the "Management Services"), and Empire hereby accepts such
engagement and agrees to perform the Management Services, subject to the
direction of the Board of Directors of SYN (the "Board") and in accordance with
the terms of this Agreement.


                      ARTICLE 2:  BUSINESS PLAN; BUDGET

      SECTION 2.01  INITIAL BUSINESS PLAN.  The parties hereto have developed a
business plan, a copy of which is attached as Exhibit A to this Agreement
("Initial Plan"), for the conduct of business operations of SYN and its
subsidiaries after the completion of the Synergy Acquisition (the "SYN
Operations"), showing:

            (a)   The general longer-term objectives (to be accomplished in a
      three to five year period of time);

            (b)   The preliminary detailed plans for conducting the SYN
      Operations through the end of SYN's fiscal year ending June 30, 1996
      ("fiscal 1996"), including the plant,


<PAGE>



      facilities and equipment (at various locations), and the personnel
      staffing at the locations, needed to carry on the SYN Operations for the
      balance of fiscal 1996 following the Synergy Acquisition and during the
      longer term of the plan; and

            (c)   Capitalized reserves for (i) transition costs  including such
      items as costs of meetings with personnel at the outlets and branches
      acquired in the Synergy Acquisition, retail mailings and other items, not
      to exceed $500,000 in the aggregate, and (ii) costs of shutting down
      Synergy's facility at Farmingdale, New York, offering severance to Synergy
      employees and incorporating Synergy's operations into Empire's facilities
      in Lebanon. Missouri.

      SECTION 2.02  INITIAL BUDGET.  The parties hereto have developed a budget
("Initial Budget") for the conduct of the SYN Operations for the balance of
fiscal 1996 following the Synergy Acquisition in accordance with the Initial
Plan.  A copy of the Initial Budget is attached as Exhibit B to this Agreement.

      SECTION 2.03  UPDATED AND AMENDED BUSINESS PLANS AND BUDGETS.  At least 30
days prior to June 30, 1996 and at least 30 days prior to each June 30
thereafter until the term of this Agreement expires or is terminated
(hereinafter sometimes referred to as the "end of the term of this Agreement"),
Empire will develop, in consultation with NGC, and obtain the approval of the
Board of:

            (a)   An updated version of the Initial Plan (or of the most recent
      previously updated version thereof) to provide a detailed business plan
      for the SYN Operations for the 18 months following such June 30 and a
      longer-term business plan for the three- to five-year period following
      such June 30 (the Initial Plan or updated version thereof in effect at a
      given time, including all amendments thereto up to such time, is
      hereinafter referred to as the "Applicable Plan"); and

            (b)   An updated version of the Initial Budget (or of the most
      recent previously updated version thereof) to provide a budget for the
      conduct of the SYN Operations for the 18 months following such June 30,
      (the Initial Budget or updated version thereof in effect at a given time
      for a particular period, including all amendments thereto up to such time,
      is  hereinafter referred to as the "Applicable Budget").

Empire may amend an Applicable Plan or an Applicable Budget, or both, at any
time and from time to time by preparing such amendment, submitting the same to
the Board with such supporting information as the Board may require, and
obtaining the Board's approval thereof, but no such amendment shall be effective
unless and until approved by the Board.

      SECTION 2.04  ACTING WITHIN APPLICABLE PLAN AND BUDGET.  Empire shall
manage the SYN Operations, commencing with the Synergy Acquisition and
continuing thereafter until the end of the term of this Agreement, in accordance
with the Applicable Plan and within the Applicable Budget, without obtaining
approval of the Board of the details of such management, but subject to
approvals by the Board required by law and to the requirements for approval by
the Board specified in Article 9 herein.  Notwithstanding the foregoing:



                                        2
<PAGE>



            (a)   Empire may take such management action with respect to the SYN
      Operations as it may deem advisable to respond to, and attempt to curtail
      or avoid material adverse consequences resulting from material unplanned
      adverse developments when (reasonably) there is inadequate time in which
      to secure advance approval of such action by the Board, but in such event
      the situation and action taken shall be submitted with reasonable
      promptness to the Board for such further action as the Board may then deem
      advisable;

            (b)   In addition to action taken pursuant to preceding paragraph
      (a), Empire may cause SYN to make maintenance capital expenditures which
      individually exceed the Applicable Budget for such expenditures or
      category of expenditures by not more than $10,000, but only if the Board
      is notified prior to, or at, the time of such expenditures, while such
      expenditures in excess of such $10,000 limit may not be made or committed
      to unless authorized in advance by the Board; and

            (c)   If Empire becomes aware that aggregate operating or
      administrative expenses likely will be 1% or more in excess of what is
      provided for in the then Applicable Budget, Empire shall promptly notify
      the Board of such expected excess.

      SECTION 2.05  OTHER ACTION.  Any action that needs to be taken in the
performance of the Management Services that is not provided for in an Applicable
Plan or Applicable Budget or otherwise provided for in this Agreement shall be
taken in accordance with Empire's good faith judgment as to what is in the best
interests of SYN and its subsidiaries.


              ARTICLE 3:  EMPIRE'S SERVICES; KEY MAN INSURANCE

      SECTION 3.01  EFFORT REQUIRED.  Empire, under the management of Paul S.
Lindsey, Jr. ("Lindsey") as the chief executive officer of Empire, shall devote
sufficient time and resources to reasonably assure successful performance by
Empire for SYN of  the Management Services in accordance with this Agreement.

      SECTION 3.02  KEY MAN INSURANCE.  To compensate SYN for the loss of
services that would occur in the event of Lindsey's death, at all times while
this Agreement is in effect SYN may maintain in effect (at SYN's expense)
insurance on the life of Lindsey in an amount not less than $10,000,000, payable
to SYN, and Lindsey will cooperate by providing personal information and taking
physical examinations as required by the insurance carrier for issuing and
maintaining such insurance coverage.  The cost of such insurance shall not be
charged, directly or indirectly, in any way to Empire or to any of the
compensation due Empire under this Agreement.  At the end of the term of this
Agreement, or at such earlier time as the Board determines that SYN no longer
needs the insurance coverage provided for in this Section, Lindsey will have the
option to purchase ownership of such insurance policies from SYN for a price
equal to any cash surrender value of the insurance.

                     ARTICLE 4:  COMPENSATION OF EMPIRE

      SECTION 4.01  COMPENSATION ENTITLEMENT.  As compensation in full for
Empire's services under this Agreement, SYN shall pay Empire a Fixed Fee (as
defined in Section 4.02 hereof) per annum and a Management Fee (as defined in
Section 4.03 hereof).

      SECTION 4.02  FIXED FEE.  The Fixed Fee (the amount of which for each
fiscal year of SYN, or part thereof, will be included in the Applicable Budget
for such period), is intended to cover Empire's operating overhead in performing
its services under this Agreement.  The Fixed Fee shall be paid by SYN to Empire
in equal monthly installments in advance, upon commencement of Empire's services
and thereafter on the first day of each month, and shall be at the initial
annual rate of $3,250,000 for the period commencing with the commencement of
Empire's services under this Agreement and ending June 30, 1996, and for each
12-month period or portion thereof thereafter until the end of the term of this
Agreement the annual rate of the Fixed Fee shall increase by the percentage
increase in the Consumer Price Index, All Items For All Urban Consumers, U.S.
City Average (1982-84 = 100), as of the start of such period as determined by
the index number for the month most recently published by the U.S. Department of
Labor or any successor governmental agency handling such publication, as of the
start of the period, compared to 151.4 (which is such index figure for the month
of March, 1995), but no reduction in the annual rates of the Fixed Fee shall be
made if a decrease in such Consumer Price Index figure shall occur.  In addition
to the foregoing adjustments in the Fixed Fee related to changes in such
Consumer Price Index, the Fixed Fee shall be adjusted in an amount approved by
the Board to reflect Empire's increased fixed operating overhead reasonably
attributable to increases in SYN's business resulting from acquisitions and
start-ups of business locations after the Synergy Acquisition is completed.  In
the event of changes in the basis for such Consumer Price Index, or such index
is discontinued, the parties shall amend this Section 4.02 to provide as closely
as possible for the same adjustment mechanism, using the changed basis or a
different published index, as appropriate.

      SECTION 4.03  MANAGEMENT FEE.  The Management Fee, an estimate of which
for each fiscal year shall be included in the Applicable Budget for such period,
shall be at the annual rate of $500,000 per annum, payable by SYN to Empire in
equal monthly instalments in advance upon commencement of Empire's services and
thereafter on the first day of each month, plus a sum (the "Additional Amount")
equal to 10% of the amount by which the EBITDA for SYN and its subsidiaries, on
a consolidated basis, exceeds the amount shown below for each period indicated,
with the Additional Amount for each such period to be paid by SYN to Empire
within 90 days after the end of such period or at such earlier time as the final
calculation of the Additional Amount for such period is completed:

            $17,500,000 for the period ending June 30, 1996;
            $18,000,000 for the 12 months ending June 30, 1997;
            $18,300,000 for the 12 months ending June 30, 1998;
            $18,600,000 for the 12 months ending June 30, 1999; and
            $18,900,000 for the 12 months ending June 30, 2000;

For purposes of this Agreement, "EBITDA" means earnings before interest, taxes,
depreciation and amortization for a specified period for the specified
corporation, or the specified group of corporations on a consolidated basis, or
the specified business locations, determined from financial


                                        4
<PAGE>



statements for such corporation or corporations or business locations prepared
on the basis of generally accepted accounting principles, consistently applied.


                ARTICLE 5:  COMPETITION BETWEEN EMPIRE AND SYN

      SECTION 5.01  OVERLAPPING MARKET AREAS.  As promptly as is reasonably
possible, Empire and SYN shall use their best efforts to exchange those outlets
of Empire and SYN that are designated in Exhibit C attached to this Agreement as
having overlapping, competing market areas, by having some of the SYN outlets
listed on such Exhibit C transferred to Empire and some of the Empire outlets
listed on such Exhibit C transferred to SYN, such that upon completion of these
transfers, the SYN outlets transferred to Empire will have EBITDA (as defined in
Section 4.03 herein) and assets equivalent (with immaterial exceptions) in
value to the Empire outlets transferred to SYN,  and the overlapping, competing
nature of the market areas shown on Exhibit C will be eliminated by such
transfers.  Any shortfall of EBITDA or asset value to either party from such
transfers shall be compensated by either a transfer of assets or a cash payment,
the amount of which is to be negotiated between NGC and SYN, as one party, and
Empire, as the other party.

      SECTION 5.02  NON-COMPETITION; ACQUISITIONS.

            (a)   While this Agreement is in effect and for a period of one year
      thereafter, Empire and SYN will not solicit customers and employees from
      each other.

            (b)   Until the end of the term of this Agreement and for a period
      of two years thereafter, Empire and SYN shall not compete in each others
      area of interest for new customers within such area.  Regarding individual
      acquisitions of retail propane businesses greater than $7,500,000 which
      any party hereto desires to make before the end of the term of this
      Agreement, such acquisitions shall be owned jointly by Empire and SYN in
      relation to the capital provided for such acquisition or such other
      arrangements as can be negotiated by such parties on a case by case basis,
      but acquisitions less than $7,500,000 shall be pursued first by the
      individual entity with operations closest to the acquired property, or if
      not successfully pursued by such party, then jointly by Empire and SYN
      together, based on capital provided, and if not successfully pursued by
      those two parties, then by whichever (Empire or SYN) was not such first
      party.


                 ARTICLE 6:  ACCOUNTING SYSTEM; ACCOUNTANTS

      SECTION 6.01  ACCOUNTING SYSTEM.  At all times until the end of term of
this Agreement, Empire will:

            (a)   Cause SYN and its subsidiaries to implement and maintain a
      system of accounting for the assets, liabilities, operations and cash
      flows of SYN and its subsidiaries, and internal controls over accounting
      and financial matters for SYN and its subsidiaries, similar to the system
      and controls maintained by Empire for itself, or, if requested by the
      Board, as the Board shall reasonably require; and in connection with the
      foregoing, Empire shall cause SYN to provide NGC with such financial
      statements and reports with respect to assets, liabilities, operations and
      developments affecting the business or assets of SYN and


                                        5
<PAGE>



      its subsidiaries , as NGC may require (taking into account the accounting
      and reporting requirements of NGC's parent corporation, Northwestern
      Public Service Company); and

            (b)   Cause SYN to engage a so-called "Big Six" firm of independent
      public accountants (or whatever, at the time, is the equivalent of the
      present Big Six) approved by the Board to make quarterly reviews and
      annual audits of SYN and its subsidiaries; but to the most efficient
      extent possible, Empire shall cause SYN to engage Baird, Kurtz & Dobson
      ("BK&D") to perform detailed compliance work to assist the designated firm
      of independent accountants in completing the quarterly reviews and annual
      audits.

      SECTION 6.02  AUDIT OR REVIEW.  At all times until the end of the term of
this Agreement, Empire will allow the Board and its authorized representatives,
upon at least seven-days' prior notice to, and in coordination with, the
President and Chief Executive Officer of SYN, to audit or review the books of
account and records of all kinds kept for SYN, inspect SYN's properties, consult
with SYN's personnel and with Empire's personnel involved in Empire's
performance of services under this Agreement, and generally to observe and
monitor the operation, management and accounting for SYN's business and assets;
provided, however, that such review and/or audit shall not last longer than five
business days unless Empire is in default under this Agreement.  Such reviews
shall be restricted to no more than once a month at the home office of SYN, as
maintained by Empire, through June 30, 1996 and quarterly thereafter, and
unrestricted at all of SYN's retail locations.  All reports resulting from these
audits or reviews shall be promptly furnished to the Board.


                        ARTICLE 7:  INSURANCE FOR SYN

            In addition to the key man insurance which SYN may maintain pursuant
to Section 3.02 herein, at all times while this Agreement is in effect insurance
covering liability exposures of SYN and its Board, with types and amounts of
coverages as shall be approved by the Board, shall be obtained and maintained
for SYN and its subsidiaries (at SYN's expense, and at no cost to Empire) by
Empire as part of the Management Services.  Empire shall be named as a
co-insured under such coverages.  The cost of such insurance shall be included
in each Applicable Budget.


              ARTICLE 8:  ATTENDANCE OF EMPIRE'S BOARD MEETINGS

            At all times while this Agreement is in effect, NGC will designate a
representative who may, as invited, be allowed to attend quarterly meetings of
Empire's Board of Directors and to receive copies of all information  supplied
by Empire to the members of its Board of Directors for such meetings.


                   ARTICLE 9:  SYN BOARD APPROVAL REQUIRED

            The assets and business of SYN and its subsidiaries shall be managed
as provided herein by Empire while this Agreement remains in effect, subject to
the overall direction and supervision by the Board.  However, Empire shall not
take for SYN (such term at all times in this


                                        6

            (c)   Cause SYN to incur any indebtedness for borrowed money

      of seller financing of the purchase of particular assets;

            (d)   Mortgage or otherwise grant a lien upon or security interest

      in payment for goods and services in the ordinary course of business in
      amounts less than $50,000;

            (f)   Cause SYN to enter into any joint venture or similar

            (iii) If any of the terms of this Agreement are changed without the

      SECTION 11.02  TRANSITION UPON TERMINATION.

            (a)   Upon expiration or earlier termination of this Agreement, the
      parties hereto will cooperate to the fullest extent possible to facilitate
      the creation of a staff of management personnel, and the establishment of
      facilities owned or leased by SYN or otherwise available for use by SYN on
      terms acceptable to SYN, to enable SYN to plan and manage its business
      operations and assets without the services that would have been provided
      by Empire under this Agreement had this Agreement remained in effect; and
      until that is accomplished (and the parties hereto shall make a good faith
      effort to accomplish it promptly), SYN shall have the use of the personnel
      and facilities of Empire that had been devoted in whole or in part to such
      planning and management at a cost not to exceed the amount most recently
      budgeted therefor in the last Applicable Budget, or at Empire's cost in
      the absence of such budgeted amount.

            (b)   Notwithstanding the foregoing, in the event this Agreement is
      terminated by Empire, SYN shall have up to 18 months (including the
      12-months' notice period) to plan and execute an operational and
      transition plan for achieving what is provided for in preceding subsection
      (a).

      SECTION 11.03  PUTS AND CALLS.

            (a)   In the event this Agreement is terminated by Empire, SYN shall
      have a call right to purchase Empire's shares of common stock of SYN at a
      price equal to 100% of fair market value, determined by appraisal, and
      Empire shall have a put right to sell to SYN Empire's shares of common
      stock of SYN at a price equal to 90% of fair market value, determined by
      appraisal, provided that, in case of a put by Empire, SYN has adequate
      liquidity, as reasonably determined by its Board, to make such purchase.

            (b)   In the event this Agreement is terminated by SYN, SYN shall
      have a call right to purchase Empire's shares of common stock of SYN at a
      price equal to 110% of fair market value, determined by appraisal, and
      Empire shall have a put right to sell to SYN Empire's shares of common
      stock of SYN at a price equal to 100% of fair market value, determined by
      appraisal, provided that in the case of a put by Empire, SYN has adequate
      liquidity, as reasonably determined by its Board, to make such purchase.

            (c)   For these purposes, fair market value of the shares of  common
      stock of SYN to be sold and purchased shall be determined by an appraiser
      or investment banker selected as provided in Section 1.04(a)(ii) of the
      Stock Agreement, with the appraisal made in accordance with such Section.


                     ARTICLE 12:  RIGHT OF FIRST REFUSAL

      So long as this Agreement is in effect, Empire will require Lindsey not to

<PAGE>



party or to Empire management personnel, provided that Lindsey retains voting
control of Empire), and Empire will not sell or otherwise dispose of all or
substantially all of its business and assets, whether such transactions are to
be done directly or indirectly by means of a merger or consolidation of Empire
with the acquiring entity, without first offering the same for sale to NGC, on
the same terms as are offered by the other party (with full disclosure of such
terms to NGC), and allowing not less than 30 days after its receipt of the offer
for NGC to accept the offer, and if such offer is accepted by NGC, NGC shall
have 90 days in which to complete the purchase on such terms.

             AGREEMENT AMONG INITIAL STOCKHOLDERS AND SYN INC.


      THIS AGREEMENT, dated May 17, 1995, is made and entered into among Empire
Gas Corporation, a Missouri corporation ("Empire"), Northwestern Growth
Corporation, a South Dakota corporation ("NGC"), and SYN Inc., a Delaware
corporation ("SYN"), with respect to the following facts:

      A.    Empire currently is engaged in the business of distributing and
selling at retail liquified petroleum ("LP") gas and appliances, and has a
management experienced in the operation of such business.

      B.    NGC is a wholly-owned subsidiary of Northwestern Public Service
Company ("NWPS") and has as one of its objectives the making of investments that
could benefit NWPS and its stockholders.

      C.    Empire and NGC, acting together, have made a successful bid to
acquire the LP gas distribution and appliance business of Synergy Group
Incorporated ("Synergy"; such acquisition being hereinafter called the "Synergy
Acquisition"), in what is planned to be the first step in the proposed
development by Empire and NGC, on a team basis, of a significant position in the
LP gas distribution industry.  Empire and NGC have contemplated, in their
bidding for the Synergy Acquisition, that they will rely principally on Empire
for management expertise and on NGC to provide or arrange the financing for the
Synergy Acquisition, and that the success of the Synergy Acquisition will depend
in large measure upon the cost savings and operating improvements expected to be
achieved by having Empire do the planning and management of the business of
Synergy and its subsidiaries, under the direction of the Board of Directors of
SYN.

      D.    Empire and NGC have caused SYN to be incorporated to serve as the
vehicle (directly or through subsidiaries to be created) for making the Synergy
Acquisition.

      E.    Empire and NGC, on behalf of SYN, are concluding the negotiation of
the definitive agreement (the "Synergy Acquisition Agreement") for the Synergy
Acquisition, and need to provide for (i) the initial capitalization of SYN, (ii)
certain loan financing for SYN, (iii) the management of SYN and (iv) for certain
matters pertaining to the ownership of shares of stock of SYN.

      NOW THEREFORE, in consideration of the premises and the agreements
exchanged herein, the parties hereto agree as follows:


                  ARTICLE 1:  INITIAL CAPITALIZATION OF SYN;
                STOCK SUBSCRIPTIONS AND RESERVATIONS OF STOCK

      SECTION 1.01  INITIAL AUTHORIZED STOCK OF SYN.  SYN has been
incorporated by Empire and NGC with an initial authorized capitalization (as set
forth in Article FOURTH of SYN's Certificate of Incorporation, a true and
complete copy of which is attached hereto as Exhibit A), consisting of 100,000
shares of common stock, par value 1E per share (the "Common Stock"; and the
100,000 shares of Common Stock referred to herein shall only be increased with
the prior written agreement of Empire and NGC unless such increased number of
shares is to be issued in an arm's length


<PAGE>



transaction to a party who is not affiliated with any of the parties to this
Agreement), and 100,000 shares of preferred stock, par value 1E per share,
issuable in one or more series (the "Preferred Stock").  Prior to the
consummation of the Synergy Acquisition, SYN shall, and Empire and NGC shall
cause SYN to, take all action necessary to create and authorize the issuance of
a series of the Preferred Stock, namely, the Series A Cumulative Preferred
Stock, consisting of 70,500 shares, the terms of which shall be as set forth in
Exhibit B attached hereto, with such changes therein as the parties hereto may
approve before such series is created (the "Series A Preferred Stock").

      SECTION 1.02  SUBSCRIPTIONS AND OPTION FOR STOCK.  NGC has previously
purchased, and hereby subscribes for, stock of SYN, and NGC has granted Empire
an option to purchase certain shares of  stock from NGC, as follows:

            (a)   SYN and NGC acknowledge that NGC has purchased from SYN, and
      SYN has sold and issued to NGC, 1,000 shares of Common Stock for a cash
      purchase price of $1,000.00 which has been paid by NGC to SYN, and that
      these shares are the only shares of stock of SYN that are currently
      outstanding.

            (b)   NGC hereby subscribes for, and agrees to purchase from SYN,
      and SYN hereby agrees to sell and issue to NGC, an additional 71,500
      shares of Common Stock for a cash purchase price of $71,500.00 to be paid
      at the time of such issuance, with this transaction to be consummated (the
      "Subscription Closing") at the First Closing, as defined in the Synergy
      Acquisition Agreement, unless an earlier time for the Subscription Closing
      is agreed to by the parties hereto.  The obligation of NGC under its
      subscription in this paragraph (b) is subject to the condition (unless
      waived by NGC) that NGC shall have been able to obtain the funds from the
      Permanent Financing or the Temporary Financing, as those terms are defined
      in the Synergy Acquisition Agreement, at or prior to the time of the
      Subscription Closing.

            (c)   NGC hereby subscribes for, and agrees to purchase from SYN,
      and SYN hereby agrees to sell and issue to NGC, 68,000 shares of Series A
      Preferred Stock for a cash purchase price of $1,000 per share
      ($68,000,000.00 total), with this transaction to be consummated at the
      Subscription Closing.  The obligation of NGC under its subscription in
      this paragraph (c) is subject to the condition (unless waived by NGC) that
      NGC shall have been able to obtain the funds from the Permanent Financing
      or the Temporary Financing, as those terms are defined in the Synergy
      Acquisition Agreement, at or prior to the time of the Subscription Closing
      and that, at the time of the Subscription Closing, the First Closing (as
      defined in the Synergy Acquisition Agreement) is concurrently occurring or
      is reasonably assured of being consummated immediately thereafter.

            (d)   Empire hereby subscribes for, and agrees to purchase from SYN,
      and SYN hereby agrees to issue and sell to Empire, 10,000 shares of Common
      Stock (which shall represent 10% of the issued and outstanding Common
      Stock) for a cash purchase price of $10,000 to be paid at the time of such
      issuance, with this transaction to be consummated at the Subscription
      Closing.  The obligation of Empire under its subscription in this
      paragraph (d) is subject to the condition (unless waived by Empire) that
      NGC consummates its purchase of shares of Common Stock under paragraph (b)
      above in this Section 1.02 at the Subscription Closing.



                                        2
<PAGE>



            (e)   NGC hereby grants to Empire an option to purchase from NGC, at
      a price of $1.00 per share, up to 20,000 of the shares of Common Stock
      which shall represent 20% of the issued and outstanding Common Stock,
      subject to NGC acquiring such shares pursuant to paragraph (b) above in
      this Section 1.02.  Such option may be exercised at any time after
      September 30, 1995 and prior to September 30, 1997, or the Determination
      Date (as defined in Section 1.04 herein), whichever is earlier, by
      Empire's giving written notice of such exercise to NGC.  After the giving
      of such notice, NGC shall assign and deliver to Empire the shares of
      Common Stock for which the stock option was exercised, as promptly as
      possible, but in any event within seven days, in exchange for Empire's
      payment to NGC of the purchase price for such shares; and the shares so
      assigned and delivered shall then be shares owned by  Empire and shall be
      held by Empire subject to the terms of this Agreement.

      SECTION 1.03  RESERVATIONS OF STOCK FOR ISSUANCE.  SYN shall, and
Empire and NGC shall cause SYN to, take all action necessary to reserve for
initial issuance, 17,500 shares of Common Stock and 2,500 shares of Series A
Preferred Stock to be issued to the Stockholders (as defined in the Synergy
Acquisition Agreement) at the Second Closing (also as defined in the Synergy
Acquisition Agreement), pursuant to the Synergy Acquisition Agreement.

      Section 1.04  COMMON STOCK RETURN.  The following provisions of this
Section 1.04 apply in the event Empire exercises the stock option granted to it
in Section 1.02(d) herein:

            (a)   The "Common Stock Return," as that term is used herein, shall
      be the number of shares of Common Stock of SYN which Empire hereby agrees
      to assign and deliver to NGC, without cost to NGC, in the event that the
      common equity value at a Determination Date (as defined below) is below
      levels specified for such date in subparagraph (iii) in this paragraph
      (a).  The Common Stock Return shall be set in accordance with the
      following formula:

                  (i)   The Determination Date shall be the date on which SYN is
            sold (meaning a sale of substantially all of the assets of SYN and
            its subsidiaries, the acquisition of SYN by another, non-affiliated
            entity by merger or consolidation, or the sale of partnership units
            or shares of stock of SYN which entitle the holder thereof to cast
            at least a majority of the votes entitled to be cast in the general
            election of directors of SYN or the date on which the sale of
            partnership units or shares of SYN's Common Stock is closed in an
            underwritten public offering, for which the partnership units or
            shares are registered under the Securities Act of 1933, or the date
            on which this Agreement expires or is terminated in accordance with
            Section 7.02 herein, whichever of the foregoing first occurs).

                  (ii)  The value of the total outstanding Common Stock of SYN
            on the Determination Date (the "Value"), shall be determined by the
            parties hereto on the basis of the sale price for SYN if the sale of
            SYN is involved, or based upon the price to SYN (or the selling
            stockholders if SYN is not the seller) in the event an underwritten
            public offering of partnership units or Common Stock of SYN is
            involved, or on the basis of the fair market value of the
            outstanding Common Stock of SYN in every other event, as determined
            by an appraisal firm or an investment banking firm selected by the
            parties hereto, with such fair market value to be


                                        3
<PAGE>



            determined on the basis of the value of SYN and its subsidiaries as
            a whole, if sold as a going concern.  In the event there is a
            combination of one or more entities with SYN, the value of SYN will
            be determined by either (x) a fair market value appraisal or (y) in
            the event there is a public offering within nine months after such
            combination, the value shall be the initial price to the public of
            the SYN shares of Common Stock or partnership units in such public
            offering.

                  (iii) For these purposes, "deemed outstanding shares of Common
            Stock" shall be the total of the number of shares of Common Stock
            issued and outstanding, plus the number that would be issued and
            outstanding if all outstanding stock options, warrants, conversion
            rights and other rights to acquire shares of Common Stock were
            exercised, whether or not exercisable at the time.  The number of
            shares of Common Stock of SYN constituting the Common Stock Return
            shall be the percentage of the deemed outstanding shares of Common
            Stock of SYN as of the Determination Date, determined on the basis
            of the following table and paragraph (b) below, if applicable:

      Return shall be a figure between 7.5% and 0% which is in proportion to
      what the Value is to the amounts in the two columns for the particular
      Determination Date.

      SECTION 1.05  ACQUISITION FOR INVESTMENT.  Empire and NGC each
represent and warrant to the other, and to SYN, as follows:  It has (through its
management personnel) such knowledge and experience in financial and business
matters that it is capable of evaluating the merits and risks of its purchase of
securities of SYN as provided for in this Agreement; it is acquiring such
securities, and will acquire them, for investment and not with a view toward, or
with any intention of,


                                        4
<PAGE>



distributing or selling any of the securities and it will not sell or offer to
sell or otherwise transfer any of the securities in violation of the Securities
Act of 1933, as amended.


                     ARTICLE 2:  LOAN FINANCING FOR SYN

      NGC shall make a commercially reasonable effort to arrange for SYN, or
provide SYN with, loan financing for SYN, on a fully secured basis, of up to
$70,000,000 principal amount needed by SYN for the Synergy Acquisition.


                 ARTICLE 3:  LIMIT TO FINANCING OBLIGATIONS

      Neither Empire nor NGC, nor any of their affiliates, shall have any

provided for in Articles 1 and 2 herein.


                       ARTICLE 4:  SYNERGY ACQUISITION

      Each of the parties hereto will make a commercially reasonable effort in
cooperation with the other parties hereto, to do those things within its control
to consummate the Synergy Acquisition in accordance with the terms of, and
subject to the conditions in, the Synergy Acquisition Agreement.  Nothing in
this Agreement or otherwise shall be construed to give anyone who is not a party
to this Agreement, whether under a third party beneficiary legal doctrine or
otherwise, a right to enforce the provisions of this Article or to obtain relief
for any failure to perform in accordance with the requirements of this Article.


                        ARTICLE 5:  MANAGEMENT OF SYN

      SECTION 5.01  At or before the First Closing (as defined in the Synergy

      SECTION 5.02  DIRECTORS AND OFFICERS OF SYN.

            (a)   For purposes of this Agreement, "Control Period" means the
      period of time commencing on the date of this Agreement and continuing

      SYN deemed to be outstanding (determined as provided in Section 1.04
      herein), (C) Empire no longer owns at least 20%
