AGREEMENT OF PURCHASE AND SALE OF STOCK This AGREEMENT OF PURCHASE AND SALE OF STOCK, dated as of April 1, 1998 (the "Agreement"), is made and entered into by and among ONSITE ENERGY CORPORATION, a Delaware corporation ("Onsite") and Russell William Royal ("Royal") and Keith Aldrich ("Aldrich"), the sole shareholders of LIGHTING TECHNOLOGY SERVICES, INC., a California corporation ("LTS"). Royal and Aldrich, together, shall be referred to as the "LTS Shareholders." WITNESSETH WHEREAS, the Board of Directors of Onsite has approved and deems it advisable and in the best interest of its stockholders to effect the acquisition of LTS by Onsite through a stock purchase under the terms and subject to the conditions set forth herein; and WHEREAS, the LTS Shareholders own an aggregate of 40,000 shares of Series 1 (Voting) Common Stock (the "LTS Shares"), representing all of the outstanding capital stock of LTS. NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants, and agreements set forth herein, the parties hereto agree as follows: I. PURCHASE AND SALE OF THE LTS SHARES 1.1 SALE AND TRANSFER OF LTS SHARES. Subject to the terms and conditions set forth in this Agreement, the LTS Shareholders will transfer and convey the LTS Shares to Onsite, and Onsite will acquire the LTS Shares from the LTS Shareholders, on the Closing Date (as defined in Section 1.5 below). 1.2 INITIAL CONSIDERATION. As initial consideration for the LTS Shares, upon the Closing of this Agreement, Onsite shall issue to the LTS Shareholders a total of 690,000 shares of Onsite's Class A Common Stock, $.001 par value (the "Onsite Shares"), pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act") under Section 4(2) of the Securities Act and Rule 505 of Regulation D thereunder, and $500,000 in cash (the "Cash Consideration"). 1.3 EARN-OUT PAYMENT. Unless otherwise agreed to by the parties as a result of the audit of the financial statements of LTS to be conducted pursuant to Section 4.5(g) hereof, as additional consideration for the LTS Shares, if the Net Income of LTS, as defined below, for the period from April 1, 1998 to March 31, 1999, exceeds $278,414, Onsite shall either, in its sole discretion,(a) pay to the LTS Shareholders, in equal proportion, a cash amount equal to the Income Eligible for Earn-Out (as defined below), less $278,414, multiplied by five (5) (the "Cash Amount"), or (b) issue to the LTS Shareholders, in equal proportion, an aggregate number of shares of Onsite <PAGE2> Class A Common Stock, $.001 par value, equal to the Cash Amount divided by the average closing price of Onsite's Class A Common Stock for the twenty (20) business days preceding March 31, 1999 (the "Earn-Out Shares"). (a) "Net Income" is defined as total operating revenues earned less all operating expenses, including salaries and other compensation, and excluding income taxes, interest paid to Onsite, Special Legal Expenses (as defined in Section 1.3(h) below) and any charges for Onsite's administrative costs on behalf of LTS (including the agreed charge of $1,750 per month), unless otherwise agreed by the LTS Shareholders and Onsite, all in accordance with GAAP, applied consistently with the audit to be conducted pursuant to Section 4.5(g) hereof, and subject to the approval of auditors of Onsite. The parties agree, however, that with respect to any warranty and/or bad debt reserves applied to LTS's net revenues by Onsite's auditors, the LTS Shareholders may receive additional Earn-Out Shares (or Cash Amount) as follows: (i) Bad Debt Reserve. Following the 12-month period ending March 31, 2000, the parties shall review the collection of any bad debts for which reserves had been created that reduced the Net Income of LTS for the 12- month period ending March 31, 1999. If any such debt was actually collected, the LTS Shareholders shall be entitled to the additional Earn-Out Payment (subject to adjustment for any stock split, stock dividend, reverse stock split or similar transaction after March 31, 1999) that would have been paid if the bad debt reserve had not included that collected debt, which shall be paid no later than June 15, 2000. (ii) Warranty Reserve. For any warranty reserve that reduced the Net Income of LTS for the 12-month period ending March 31, 1999, the parties shall review the actual expenses associated with warranty services during each subsequent year for the duration of each warranty covered by such reserve. If any such warranty expenses prove to be less than the amount reserved for that warranty, the LTS Shareholders shall be entitled to the additional Earn-Out Payment (subject to adjustment for any stock split, stock dividend, reverse stock split or similar transaction after March 31, 1999) that would have been paid if the warranty reserve had only reflected such actual warranty expenses, which shall be paid no later than 75 days after the end of each such year. (b) "Income Eligible for Earn-Out" is defined as the Net Income of LTS (as defined above), less any Gross Profit Margin attributed to "Onsite- initiated Projects," as defined below, in excess of $460,000. (c) "Gross Profit Margin" is defined as gross revenues less all direct material, direct labor, direct sales tax and direct miscellaneous expenses, unless otherwise agreed by the LTS Shareholders and Onsite. (d) "Onsite-initiated Project" is defined as any project for which Onsite has initially identified the customer and has taken primary responsibility in securing an executed contract with the customer. Exhibit A sets forth the present Onsite-initiated Projects, and is subject to periodic updates by the parties. <PAGE3> (e) Notwithstanding the calculation above, the maximum number of Earn-Out Shares which may be issued is 3,310,000, subject to adjustment for any stock split, stock dividend, reverse stock split or similar transaction. Similarly, the maximum Cash Amount shall not exceed the average closing price of Onsite's Class A Common Stock for the twenty (20) business days preceding March 31, 1999 multiplied by 3,310,000 (subject to similar adjustments). (f) The payment of the Cash Amount or issuance of the Earn-Out Shares pursuant to this Section 1.3 is a one-time incentive based on the income and revenues of LTS for the period from April 1, 1998 to March 31, 1999 only. (g) The payment of the Cash Amount or issuance of the Earn-Out Shares, if any, shall be completed within 30 days of the completion of a review or audit by Onsite's auditors, but not later than June 15, 1999. (h) "Special Legal Expenses" is defined as any liabilities, costs and expenses (including attorneys' fees) incurred by LTS after March 31, 1998 as a result of or relating to the litigation referred to in Section 2.10 of the Disclosure Schedule or in connection with the negotiation, review and preparation of this Agreement and the exhibits hereto. Although the Special Legal Expenses will not be deducted to determine Net Income, the LTS Shareholders will be responsible to reimburse LTS for any Special Legal Expenses paid by LTS as follows. With respect to any such Special Legal Expenses paid by LTS before the earlier of June 15, 1999 or the date the Cash Amount is paid or the Earn-Out Shares are issued (the "Payment Date"), the total amount of such Special Legal Expenses paid by LTS (without interest thereon) shall be deducted from the amount of the Cash Amount that would otherwise apply for purposes of this Section 1.3. If the amount of the Cash Amount is less than the total amount of such Special Legal Expenses, each LTS Shareholder will pay to LTS on the Payment Date an amount equal to one-half ( 1/2 ) of the shortfall, by a cash payment and/or by surrendering shares of Onsite Class A Common Stock valued at their average closing price for the twenty (20) business days preceding that date. With respect to any Special Legal Expenses paid by LTS after the Payment Date, each LTS Shareholder agrees to reimburse LTS on demand for one-half ( 1/2 ) of the total amounts paid, provided that LTS shall not agree to make any such payment without the written consents of the LTS Shareholders, which consents shall not be unreasonably refused. On the Payment Date, each LTS Shareholder shall grant to LTS, as collateral security for such LTS Shareholder's obligations under the preceding sentence, a security interest in a number of shares of Onsite Class A Common Stock equal to one half ( 1/2 ) of: (a) the dollar amount of any reserve then contained on Onsite's balance sheet with respect to any litigation referred to in Section 2.10, (b) divided by the average closing price of the Onsite Class A Common Stock for the twenty (20) business days preceding that date. Quarterly thereafter (on the same date of each successive third calendar month), the number of shares subject to such security interest shall be increased or decreased, as appropriate, to equal one-half ( 1/2 ) of: (c) the dollar amount of any reserve then contained on Onsite's balance sheet with respect to any litigation referred to in Section 2.10, (d) divided by the average closing price of the Onsite Class A Common Stock for the twenty (20) business days <PAGE4> preceding that date. The LTS Shareholders agree to sign any financing statements or other documentation reasonably requested by Onsite to evidence or perfect such security interests. 1.4 CONDITIONS PRECEDENT TO CLOSING. All obligations of the parties under this Agreement are subject to the fulfillment, prior to or at the Closing Date, of all conditions herein set forth, including, but not limited to, receipt by the appropriate party of all deliveries required by Section 1.6, and fulfillment, prior to the Closing Date, of each of the following conditions: (a) Onsite shall have received the first draw due to it under the Performance Based Energy Savings Agreement with Unified School District #500 of Wyandotte County, Kansas executed on March 31, 1998.

The LTS Shareholders (and/or their purchaser representatives, if any) have had full access to the books and records of Onsite and to its officers, directors and accountants for the purpose of obtaining and verifying such information and the LTS Shareholders have had an opportunity to ask questions and receive answers from the officers of Onsite regarding the terms and conditions of this transaction and Onsite's business and financial condition. Except as set forth in the Onsite SEC Documents provided, no representations or warranties, oral or otherwise, have been made to you, including without limitation, any representations concerning the future prospects of Onsite, by Onsite or any agent, employee or affiliate of Onsite, or any other person whether or not associated with this transaction, and in entering into this transaction the LTS Shareholders are not relying upon any information, other than that contained in the documents provided, and the results of their own independent investigation. The LTS Shareholders have <PAGE13> obtained sufficient information to evaluate the merits and risks of the investment and to make an informed investment decision. 2.19 RESTRICTED SECURITIES. The LTS Shareholders understand and acknowledge that the Onsite Shares and the Earn-Out Shares they are receiving hereunder are "restricted securities" under federal and state securities laws insofar as they have not been registered under the 1933 Act or the securities laws of any other jurisdiction, that they may not be resold or transferred without compliance with the registration or qualification provisions of the 1933 Act or applicable federal and state securities laws of any state or other jurisdiction or an opinion of counsel that an exemption from such registration and qualification requirements is available. The LTS Shareholders are familiar with SEC Rule 144 as presently in effect and the resale limitations imposed thereby and by the 1933 Act. 2.20 AGREEMENT WILL NOT CAUSE BREACH. The consummation of the transactions contemplated by this Agreement will not result in either (i) a default or event that, with notice, lapse of time or both, would be a default, breach or violation of any lease, license, promissory note, conditional sales contract, commitment, indenture, mortgage, deed of trust, or other agreement, instrument or arrangement to which the LTS Shareholders or LTS is a party or by which any of them or the property of any of them is bound, or (ii) an event that would permit any party to terminate any agreement or to accelerate the maturity of any indebtedness or other obligation of LTS. III. REPRESENTATIONS AND WARRANTIES OF ONSITE Except as otherwise provided, as of the date hereof, Onsite represents and warrants to the LTS Shareholders as follows: 3.1 ORGANIZATION. Onsite is a corporation duly organized, validly existing, duly qualified or licensed to do business and in good standing under the laws of the jurisdiction of its incorporation and in each jurisdiction in which the nature of the business conducted by it makes such qualification or licensing necessary, and has all requisite corporate or other power and authority and all necessary governmental approvals to own, lease, and operate its properties and to carry on its business as now being conducted, except where the failure to be so organized, existing, and in good standing or to have such power, authority, and governmental approvals would not have a material adverse effect on Onsite and its subsidiaries, taken as a whole. 3.2 CAPITALIZATION. The authorized capital stock of Onsite consists of 24,000,000 shares of Onsite Common Stock, consisting of 23,999,000 shares of Class A Common Stock, $.001 par value per share (the "Common Stock"), and 1,000 shares of Class B Common Stock, par value $.001 per share (the "Class B Common"), and 1,000,000 shares of preferred stock, par value $.001 per share (the "Onsite Preferred Stock").

(a) Onsite has full corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. The execution, delivery, and performance by Onsite of this Agreement and the consummation by it of the transactions contemplated hereby have been duly and validly authorized by Onsite's Board of Directors and no other corporate action on the part of Onsite or its shareholders is necessary to authorize the execution and delivery by Onsite of this Agreement and the consummation by it of the transactions contemplated hereby. This Agreement has been duly executed and delivered by Onsite and constitutes a valid and binding obligation of Onsite enforceable against Onsite in accordance with its terms, except that (i) such enforcement may be subject to applicable bankruptcy, insolvency, or other similar laws, now or hereafter in effect, affecting creditors' rights generally, and (ii) the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceeding therefor may be brought. (b) The Board of Directors of Onsite has duly and validly approved and taken all corporate action required to be taken by such Board of Directors for the consummation of the transactions contemplated by this Agreement. Onsite's purchase is not a transaction that constitutes a change in control under any of Onsite's stock option or any other benefit plans in which any employee of Onsite or any of its subsidiaries participates. 3.4 CONSENTS AND APPROVALS; NO VIOLATIONS. Except as disclosed in Section 3.4 of the Disclosure Schedule, attached to this Agreement as Exhibit B2, and for filings, permits, authorizations, consents, and approvals as may be required under, and other applicable requirements of, the Securities Act and the Securities Exchange Act of 1934, as amended (the "Exchange Act"), neither the execution, delivery, or performance of this Agreement, nor the consummation by Onsite of the transactions contemplated hereby nor compliance by Onsite with any of the provisions hereof will (i) conflict with or result in any breach of any provision of the Certificate of Incorporation or Bylaws or similar organizational documents of Onsite, (ii) require any filing with, or permit, authorization, consent, or approval of, any court, arbitral tribunal, administrative agency, or other governmental or other regulatory authority or agency (a "Governmental Entity"), (iii) result in a violation or breach of, or constitute (with or without due notice or lapse of time or both) a default (or give rise to any right of termination, amendment, cancellation, or acceleration) under, or require any consent or waiver under, any of the terms, conditions, or provisions of any note, bond, mortgage, indenture, guarantee, <PAGE15> other evidence of indebtedness, lease, license, contract, agreement (including, without limitation, project or customer agreements) or other instrument or obligation to which Onsite or any of its subsidiaries is a party or by which any of them or any of their properties or assets may be bound (a "Onsite Agreement"), or (iv) violate any order, writ, injunction, decree, statute, rule, or regulation applicable to Onsite, any of its subsidiaries or any of their properties or assets, except in the case of clause (ii), (iii) or (iv) where the failure to obtain such permits, authorizations, consents, or approvals or to make such filings, or where such violation, breaches, or defaults or the failure to obtain such consents or waivers would not, individually or in the aggregate, have a material adverse effect on Onsite and its subsidiaries, taken as a whole, and will not materially impair the ability of Onsite to consummate the transactions contemplated hereby. 3.5 SEC REPORTS AND FINANCIAL STATEMENTS. Onsite has filed with the SEC, and has heretofore made available to LTS, true and complete copies of, all forms, reports, schedules, statements, and other documents required to be filed by it and its subsidiaries since January 1, 1997, under the Exchange Act or the Securities Act (as such documents have been amended since the time of their filing, collectively, the "Onsite SEC Documents").

The LTS Shareholders shall give prompt notice to Onsite and Onsite shall give prompt notice to the LTS Shareholders, of the occurrence or non-occurrence of any event the occurrence <PAGE19> or non-occurrence of which would cause any representation or warranty contained in this Agreement to be untrue or inaccurate in any material respect at or prior to the Closing Date.

If such an insurance payment is made and an LTS Shareholder has previously made a payment to Onsite which would not have been required under this paragraph if the insurance payment had been made before the payment by the LTS Shareholder, Onsite will reimburse the LTS Shareholder for such payment by the LTS Shareholder.
