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 liquefied 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 I: 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 1 CENT 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 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 1 CENT 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 currently 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. (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: (f) The "Common Stock Return," as the 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 or 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 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: Column A Column B Column C Percentage of deemed Percentage of deemed outstanding outstanding shares of Common Stock shares of Common Stock of SYN of SYN shall be 0% if the shall be 7.5% if the Fiscal Year of Value as of Value as of SYN in which the Determination Date the Determination Date Determination is at least the is less than the Date occurs: following amount: following amount: 1996 $24,500,000 $22,250,000 1997 $30,000,000 $24,750,000 1998 $36,750,000 $27,500,000 1999 $45,000,000 $30,600,000 2000 $55,200,000 $34,000,000 After 2000 1.225 times the 1.1125 times the previous year's amount previous year's amount (g) If the Value as of the Determination Date is more than the amount in Column C in Section 1.04(a)(iii) above, but less than the amount in Column B therein, the percentage used to determine the Common Stock 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 1.06 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 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, 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.
