2 Item 2 Acquisition of Assets On October 4, 1999, the registrant, Rush Enterprises, Inc. ("Rush"), caused its wholly owned subsidiaries, Rush Truck Centers of Arizona, Inc. and Rush Truck Centers of New Mexico, Inc., to acquire substantially all of the assets of Southwest Peterbilt, Inc. and its Affiliates, Southwest Truck Center, Inc., and New Mexico Peterbilt, Inc., (collectively "Southwest") Peterbilt truck dealers. (the "Acquisition") Rush will account for the Acquisition as a purchase. The effective date of the Acquisition was October 1, 1999. The total consideration paid by Rush to Southwest was approximately $23.9 million which consisted of 355,556 shares of common stock, $.01 par value, of Rush and cash of approximately $18.3 million, of which $6.8 million was drawn under Rush's credit agreements with General Motors Acceptance Corporation and PACCAR, Inc., and $11.5 million was derived from Rush's internal funds. An additional $4.0 million in cash may be paid by Rush to Southwest based upon the achievement of certain performance based objectives. The amount of consideration paid by Rush for the assets of Southwest was arrived at through arms'-length negotiations between Rush and Southwest and was based on a variety of factors, including the historical book value and historical cash flow of Southwest, and the value of goodwill of Southwest, and the nature of the industry. Prior to the Acquisition, there was no material relationship between Rush and Southwest. The assets acquired by Rush were utilized by Southwest for sales of new and used Peterbilt trucks and parts and service. Rush intends to continue such use of acquired assets. 2

9 SOUTHWEST PETERBILT, INC. AND AFFILIATES NOTES TO COMBINED FINANCIAL STATEMENTS DECEMBER 31, 1998 (1) PRINCIPLES OF COMBINATION AND BASIS OF PRESENTATION: The accompanying financial statements present the combined financial position, results of operations and cash flows of Southwest Peterbilt, Inc. (an Arizona corporation), Southwest Truck Center, Inc. (an Arizona corporation), New Mexico Peterbilt, Inc. (a New Mexico corporation), and Southwest Truck Leasing, Inc. (an Arizona corporation) (the Companies). All four corporations are under common control of the same stockholder group. All significant intercompany transactions and balances have been eliminated in these combined financial statements. (2) DESCRIPTION OF BUSINESS: The Companies serve customers in Arizona and New Mexico from their facilities located in Phoenix, Arizona; Chandler, Arizona; Flagstaff, Arizona; Tucson, Arizona; and Albuquerque, New Mexico. Principal business activities include sales of new Peterbilt, GMC, and Ford trucks, used trucks, new and used trailers, parts, mechanical services and body shop services. Sales are generally to municipalities and companies and individuals involved in the transportation and construction industries. (3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: REVENUE RECOGNITION POLICIES Income on the sale of vehicles is recognized when the seller and customer execute a purchase contract, the vehicle is delivered and payment is negotiated according to the contract terms. Finance income related to the sale of a vehicle is recognized over the period of the respective finance contract on the effective interest rate method if the finance contract is retained by the Companies. During 1999 and 1998, no finance contracts were retained for any significant length of time by the Companies but were generally sold, either without recourse or with limited recourse, to certain finance companies concurrent with the sale of the related vehicle. Gain or loss is recognized by the Companies upon the sale of such finance contracts to the finance companies, net of a provision for estimated repossession losses and early repayment penalties. Parts and service revenue is earned at the time the Companies sell the parts to its customers, or at the time the Companies complete the service work order related to service provided to the customer's vehicle. 9

10 FAIR VALUE OF FINANCIAL INSTRUMENTS The estimated fair value of financial instruments has been determined by the Companies using available market information and valuation methodologies. Considerable judgment is required in estimating fair values. Accordingly, the estimates may not be indicative of the amounts the Companies could realize in a current market exchange. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value due to the short-term maturities of these instruments. Long-term debt and floor plan notes payable approximate fair value as rates on these instruments approximate market rates currently available for instruments with similar terms and remaining maturities. CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments with a remaining maturity of 90 days or less when purchased to be cash equivalents. INVENTORIES Inventories are stated at the lower of cost or market value. Cost is determined by specific identification for new and used truck inventory and by utilizing a method that approximates the first-in, first-out method for parts and accessories. PROPERTY AND EQUIPMENT Property and equipment are stated at cost with depreciation computed using predominantly accelerated methods over the estimated useful lives of the assets, ranging from three to ten years. Leasehold improvements are amortized, on the same basis, over 10 years, the expected length of the lease term. Accumulated amortization related to leasehold improvements was $52,652 at December 31, 1998. Maintenance and repairs are charged against income when incurred. Expenditures for major renewals, replacements and betterments, which extend the assets' estimated useful life, are capitalized. Property and equipment consisted of the following at December 31: 1998 ---------- Machinery and equipment $1,236,945 Furniture and fixtures 584,468 Service vehicles 398,093 Leasehold improvements 182,472 ---------- 2,401,978 Less - accumulated depreciation 1,704,835 ---------- $ 697,143 ========== 10

11 ALLOWANCE FOR DOUBTFUL ACCOUNTS AND REPOSSESSION LOSSES The Companies provide an allowance for doubtful accounts and repossession losses after considering historical loss experience and other factors, which might affect the collectibility of accounts receivable and the ability of customers to meet their obligations on finance contracts sold by the Companies. INCOME TAXES No provision for income taxes is included in these combined financial statements because all corporations have elected S corporation status. The stockholders, rather than the corporations, are liable for income taxes on corporate taxable income. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENT During 1998, the Companies adopted Statement of Financial Accounting Standards No. 131, Disclosures About Segments of an Enterprise and Related Information, which established revised standards for the reporting of financial and descriptive information about operating segments in financial statements. The Companies have determined that they have one reportable operating segment. Accordingly, the Companies have not presented separate financial information for their operating segment as the Companies' financial statements present their one reportable segment. INTERIM FINANCIAL REPORTING The accompanying unaudited combined interim financial statements of the Companies have been prepared in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the periods presented have been made. The results of operations for the six-month period ended June 30, 1999 are not necessarily indicative of the operating results that may be expected for the entire year ending December 31, 1999. 11

12 (4) ACCOUNTS RECEIVABLE: Accounts receivable consisted of the following: December 31, June 30, 1998 1999 ----------- ----------- Trade accounts receivable from sale of vehicles $ 590,576 $ 1,147,642 Other trade receivables 1,824,872 1,750,191 Warranty claims 327,516 371,260 Other accounts receivable 67,351 121,936 ----------- ----------- 2,810,315 3,391,029 Less - allowance for doubtful accounts and repossession losses (193,531) (249,445) ----------- ----------- $ 2,616,784 $ 3,141,584 =========== =========== (5) INVENTORIES: Inventories consisted of the following at: December 31, June 30, 1998 1999 ----------- ----------- New and used trucks and trailers $ 6,524,968 $ 6,179,367 Parts, accessories and other 3,249,361 3,139,130 Service work in process 261,178 242,205 ----------- ----------- Total inventories $10,035,507 $ 9,560,702 =========== =========== (6) FLOOR PLAN NOTES PAYABLE AND LINE OF CREDIT: The Companies maintain inventory flooring notes payable to a bank permitting maximum borrowings of $9,800,000 with interest payable monthly at LIBOR plus 2.25%. At December 31, 1998 the LIBOR rate was 5.63%. These notes are secured by and payable as specific new trucks are sold. Inventories which serve as collateral for the floorplan agreement totaled approximately $3,928,000 at December 31, 1998. The weighted average balance outstanding for the year ending December 31, 1998 related to the floor plan notes payable was approximately $3,021,000 with an average interest rate of 7.50%. The Companies have a revolving line of credit with a bank, permitting maximum borrowings of $3,500,000. Interest is payable monthly ranging from LIBOR plus 2.25% to prime. The prime rate at December 31, 1998 was 7.75%. The line matures June 30, 1999, and is secured by accounts receivable, inventory, property and equipment. Under the terms of the revolving line of credit, the Companies are obligated to comply with certain financial covenants including maintaining a certain minimum tangible net worth, current ratio and net worth ratio. At December 31, 1998, there were no balances outstanding under the line of credit and the Companies were in compliance with all debt covenants. The weighted average balance outstanding for the year ending December 31, 1998 related to the revolving line of credit was $371,000 with an average interest rate of 7.50%. 12

13 (7) LONG-TERM DEBT: Long-term debt consisted of the following at December 31: 1998 --------- Notes payable to a bank, due in monthly installments of $16,667 plus interest at prime, secured by accounts receivable, inventory and equipment Notes mature between June 1999 and March 2001 $ 292,500 Less - current portion (155,000) --------- Long-term debt, net of current portion $ 137,500 ========= Scheduled principal maturities of long-term debt are as follows: 1999 $ 155,000 2000 110,000 2001 27,500 --------- $ 292,500 ========= (8) LEASE COMMITMENTS: Rent expense under operating leases for buildings and equipment for the years ended December 31, 1998, amounted to approximately $492,000. The future minimum lease commitments under these operating leases as of December 31, 1998, are as follows: Fiscal Year Ending December 31 ----------- 1999 $ 220,887 2000 154,800 2001 83,200 2002 57,000 2003 47,500 --------- $ 563,387 ========= 13

14 (9) 401(k) PLAN: Employees who have one full year of service and have attained age 21 are eligible to participate in the Companies' Internal Revenue Code Section 401(k) Plan. Participants may defer a maximum of 10% of their compensation. The Companies will match an annually elected discretionary percentage of participants' contributions. Participants are fully vested in their compensation deferrals. The Companies' matching contributions are 100% vested after three full years of service. Matching contributions totaled approximately $54,000 for the year ended December 31, 1998. (10) MAJOR SUPPLIERS AND DEALERSHIP AGREEMENTS: The Companies have entered into dealership agreements with various companies (Manufacturers). These agreements are nonexclusive agreements that allow the Companies to stock, sell at retail and service trucks and products of the Manufacturers in the Companies' defined markets. The agreements allow the Companies to use the Manufacturer's name, trade symbols and intellectual property and expire as follows: Manufacturer Expiration Dates ------------ ---------------- Peterbilt July 20, 2000 GMC October 31, 2000 Ford Indefinite These agreements impose a number of restrictions and obligations on the Companies, including restrictions on a change in control of the Companies and the maintenance of certain required levels of working capital. Violation of such restrictions could result in the loss of the Companies' right to purchase the manufacturers' products and use of the Manufacturers' trademarks. As of December 31, 1998, the Companies' management believes it was in compliance with all the restrictions of its Manufacturer agreements. The Companies purchase most of their new vehicles and parts from PACCAR, the maker of Peterbilt trucks and parts, at prevailing prices charged to all franchised dealers. Sales of new Peterbilt trucks accounted for 88% of the Companies' new vehicle sales for the year ended December 31, 1998. (11) CONCENTRATIONS OF CREDIT RISK: Financial instruments that potentially subject the Companies to significant concentrations of credit risk consist principally of cash and accounts receivable. The Companies maintain their cash in bank deposit accounts which, at times, may exceed federally insured limits. The Companies have not experienced any losses in such accounts. Management believes it is not exposed to any significant credit risk related to cash. A majority of the Companies' business is concentrated in the United States heavy duty trucking market and related aftermarkets. The Companies control credit risk through credit approvals, and by selling certain trade receivables without recourse. Related to the Companies' finance contracts, after the finance contract is entered into, the Company generally sells the contracts to a third party. Some finance contracts are sold with recourse (see Note 12). 14

15 (12) COMMITMENTS AND CONTINGENCIES: The Companies are contingently liable to finance companies for certain notes sold to such finance companies related to the sale of trucks. The Companies' recourse liability related to sold finance contracts is generally limited to 10% to 20% of the outstanding amount of each note sold to the finance company with the aggregate recourse liability at December 31, 1998 being limited to approximately $140,000. The Companies provide an allowance for repossession losses and early repayment penalties. The Companies act as a partial self-insurer for their employee health insurance programs. Losses and claims are accrued as incurred. The Companies have purchased insurance reducing their maximum liability for any one health claim to $35,000 and the maximum annual liability for all claims in the aggregate to approximately $450,000. There are redemption agreements with all minority shareholders which provide that upon the minority shareholder's request, death or disability, or termination of employment, the Companies shall redeem all shares owned by such shareholder at a per share price derived from the book value of the Companies' stock. Minority shareholdings approximated 28.4% at December 31, 1998. The Companies are involved in certain legal proceedings arising in the normal course of business. In the opinion of management, the Companies potential exposure under pending legal proceedings is adequately provided for in the accompanying combined financial statements. (13) RELATED PARTY TRANSACTION: In 1998, the Companies entered into a verbal agreement with the Donahue Family Partnership which is under common control of the Companies' President, to lease the land and building located at 2600 W. McDowell Road, Phoenix, Arizona. The Companies make monthly lease payments to the Donahue Family Partnership, of approximately $16,000, and for the year ended December 31, 1998, the total payments to the related party were approximately $65,000. The agreement is on a month-to-month basis. Management believes the lease payments have been consummated on terms equivalent to those that prevail in an arm's-length transaction. 15

After reviewing the Contracts, Purchaser may, at its sole option, choose not to assume one or more of the Contracts, and, within 30 days of receipt by Purchaser of all information reasonably requested by Purchaser with respect to the Contracts, Purchaser shall notify Sellers of which Contracts, if any, Purchaser does not intend to assume hereunder. Except for Contracts, if any, that Purchaser notifies Sellers that it will not assume, all of 19

27 the Contracts are and shall be included in the Assets. All of the material Contracts may be assigned to Purchaser without the approval or consent of any Person, or, if such approval or consent is required, it will be obtained by Sellers and delivered to Purchaser at or prior to the Closing. 4.9 Effect of Agreement. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby will not (i) result in any breach of any of the terms or conditions of, or constitute a default under, the Articles of Incorporation or other charter documents or bylaws of either Seller, or any commitment, mortgage, note, bond, debenture, deed of trust, contract, agreement, license or other instrument or obligation to which either Seller is now a party or by which either Seller or any of their respective properties or assets may be bound or affected; (ii) result in any violation of any Governmental Requirement applicable to either Seller, the Assets or the Business; (iii) cause Purchaser to lose the benefit of any right or privilege included in the Assets; (iv) relieve any Person of any obligation (whether contractual or otherwise) or enable any Person to terminate any such obligation or any right or benefit enjoyed by either Seller or to exercise any right under any agreement in respect of the Assets or the Business; or (v) require notice to or the consent, authorization, approval or order of any Person (except as may be contemplated by the last sentence of Section 4.8).

43 12. SPECIAL CLOSING AND POST-CLOSING COVENANTS. 12.1 Further Assurances. After Closing, as and when requested by any party hereto from time to time, the other parties hereto shall and shall cause their Affiliates to execute and deliver, or cause to be executed and delivered, such documents and instruments and shall take, or cause to be taken, such further or other actions as may be reasonably necessary to carry out the purposes of this Agreement including, without limitation, executing and delivering any instrument Purchaser may request to convey the Assets to Purchaser as required by this Agreement. 12.2 Delivery of Funds and Other Assets Collected by Sellers. To the extent either Seller receives any funds or other assets in payment of receivables, or in connection with any other Assets, being sold to Purchaser pursuant hereto, Sellers shall immediately deliver such funds and assets to Purchaser and take all steps necessary to vest title to such funds and assets in Purchaser. 12.3 Change of Name of Sellers. Immediately upon the occurrence of the Closing, Sellers and Shareholder shall cease using the name "Southwest Peterbilt", "Southwest Truck Center" "Southwest Peterbilt - GMC Trucks", "Southwest Peterbilt - Ford Trucks" and "Southwest Truck Leasing" and all derivations thereof, and covenant and agree that after Closing they will not, directly or indirectly, use such names or any derivation thereof, in connection with selling, servicing, renting, leasing, insuring or financing new or used Class 3 through 8 trucks; provided (i) Shareholder may use such names for a period of one year following the Closing for the sole purpose of winding up the affairs of Sellers, so long as such use does not involve the selling, servicing, renting, leasing, insuring or financing new or used Class 3 through 8 trucks, or interfere with the use of such names by Rush or any of its Affiliates, and (ii) Seller and Shareholder may use such names in connection with selling, renting or leasing any Excluded Asset. 12.4 Access to Files. For a period of five years after the Closing, or such longer term as Sellers or Shareholder may reasonably require if any Seller or Shareholder is then involved in litigation or under investigation or audit by a governmental agency or bureau relating to Sellers or the Assets, Purchaser shall maintain and give Sellers and Shareholder and their respective representatives full access to the premises of Purchaser and full access to, and shall permit Sellers and Shareholder and their respective representatives, at their own expense, to make photocopies of, all originals of the files and records relating to Sellers or the Assets. 12.5 Exchange Act Filing; Cooperation. After the Closing, Sellers shall, at the cost and expense of Purchaser, reasonably cooperate with and provide information to Purchaser as is necessary for Purchaser to comply with its reporting obligations under the Exchange Act. 12.6 Nondisclosure of Confidential Information. (a) By Sellers and Shareholder. Sellers and Shareholder recognize and acknowledge that they have and will have access to certain confidential information of Sellers that is included in the Assets (including, but not limited to, lists of customers, and costs and 36

44 financial information) that after the consummation of the transactions contemplated hereby will be valuable, special and unique property of Purchaser. Sellers and Shareholder agree that they will not disclose, and they will use their best efforts to prevent disclosure by any other Person of, any such confidential information to, nor any discussion of any of the terms of this Agreement with, any Person for any purpose or reason whatsoever, except to authorized representatives of Purchaser. Sellers and Shareholder recognize and agree that violation of any of the agreements contained in this Section 12.6(a) will cause irreparable damage or injury to Purchaser, the exact amount of which may be impossible to ascertain, and that, for such reason, among others, Purchaser shall be entitled to an injunction, without the necessity of posting bond therefor, restraining any further violation of such agreements. Such rights to any injunction shall be in addition to, and not in limitation of, any other rights and remedies Purchaser may have at law or in equity against Sellers or Shareholder. (b) By Purchaser. Purchaser recognizes and acknowledges that it may have access to certain confidential information of Sellers that is not included in or connected with the Assets and not used or necessary for the Business that after the consummation of the transactions contemplated hereby will be valuable, special and unique property of Sellers. Purchaser agrees that it will not disclose, and will use its best efforts to prevent disclosure by any other Person of, any such confidential information to any Person for any purpose or reason whatsoever, except to authorized representatives of Purchaser. Purchaser recognizes and agrees that violation of any of the agreements contained in this Section 12.6(b) will cause irreparable damage or injury to Sellers, the exact amount of which may be impossible to ascertain, and that, for such reason, among others, Sellers shall be entitled to an injunction, without the necessity of posting bond therefor, restraining any further violation of such agreements. Such rights to any injunction shall be in addition to, and not in limitation of, any other rights and remedies Sellers may have at law or in equity against Purchaser. (c) Exceptions. The foregoing restrictions will not apply to any information which (a) becomes available to the public generally (otherwise than by reason of a breach of the provisions of this Section 12.6), (b) can be shown by written records to have been known by the disclosing party prior to the date of this Agreement or (c) is lawfully acquired by the disclosing party from another person. In the event any confidential information protected by this Section 12.6 is required to be disclosed under court or governmental order, rule or regulation, the party required to disclose such confidential information shall immediately provide the party entitled to protection hereunder with notice thereof and shall give full and complete cooperation to such party in its efforts to object to, and to obtain protection of any confidential information that is the subject of, such required disclosure. 12.7 Assignment of Contracts. Notwithstanding any other provision of this Agreement, nothing in this Agreement or any related document shall be construed as an attempt to assign (i) any Contract which, as a matter of law or by its terms, is nonassignable without the consent of the other parties thereto unless such consent has been given, or (ii) any Contract or claim as to which all of the remedies for the enforcement thereof enjoyed by Sellers would not, as a matter of law or by its terms, 37

45 pass to Purchaser as an incident of the transfers and assignments to be made under this Agreement. In order, however, that the full value of every Contract and claim of the character described in clauses (i) and (ii) above and all claims and demands on such Contracts may be realized for the benefit of Purchaser, Sellers, at the request and expense and under the direction of Purchaser, shall take all such action and do or cause to be done all such things as will, in the opinion of Purchaser, be necessary or proper in order that the obligations of Sellers under such Contracts may be performed in such manner that the value of such Contract will be preserved and will inure to the benefit of Purchaser, and for, and to facilitate, the collection of the moneys due and payable and to become due and payable thereunder to Purchaser in and under every such contract and claim. Sellers shall promptly pay over to Purchaser all moneys collected by or paid to it in respect of every such contract, claim or demand. Nothing in this Section 12.7 shall relieve Sellers or Shareholder of their obligations to obtain any consents required for the transfer of the Assets and all rights thereunder to Purchaser, or shall relieve Sellers or Shareholder from any liability to Purchaser for failure to obtain such consents. 12.8 Non-Compete, Non-Solicitation. (a) Non-Competition. In consideration of the benefits of this Agreement to Sellers and Shareholder and as a material inducement to Purchaser to enter into this Agreement and to pay the Purchase Price, Sellers and Shareholder, hereby covenant and agree that for a period of five years after the Closing Date, Sellers and Shareholder shall not, and each shall cause their Affiliates (not including any family member of Shareholder) not to, directly or indirectly, as proprietor, partner, stockholder, director, officer, employee, consultant, joint venturer, investor or in any other capacity, engage in, or own, manage, operate or control, or participate in the ownership, management, operation or control, of any entity which engages in the sale, servicing, renting, leasing, insuring or financing of new or used Class 3 through 8 truck (not including construction equipment) in any geographical or commercial markets in which Rush or any of its Affiliates (including Purchaser) conducts business on the Closing Date; provided, however, the foregoing shall not, in any event, prohibit Sellers or Shareholder from (i) purchasing and holding as an investment not more than 1% of any class of publicly traded securities of any entity which conducts such business, so long as neither of Sellers nor Shareholder participate in any way in the management, operation or control of such entity or (ii) selling, leasing or otherwise disposing of any vehicles, parts and accessories inventory or chassis kits held by the Business as of the Closing Date that are not transferred to Purchaser pursuant to the terms of this Agreement. It is further recognized and agreed that, even though the activity may not be restricted under the foregoing provision, for a period of five years following the Closing Date, neither Sellers nor Shareholder shall, and each shall cause their Affiliates not to, provide any services to any person or entity which may be used against, or in conflict with the interests of, Purchaser or an Affiliate of Purchaser. (b) Judicial Reformation. Sellers and Shareholder acknowledge that, given the nature of Purchaser and its Affiliates' business, the covenants contained in this Section 12.8 establish reasonable limitations as to time, geographic area and scope of activity to be 38

46 restrained and do not impose a greater restraint than is reasonably necessary to protect and preserve the goodwill of Purchaser and its Affiliates' business and to protect their legitimate business interests. If, however, this Section 12.8 is determined by any court of competent jurisdiction or an arbitrator pursuant to Section 20.1 to be unenforceable by reason of it extending for too long a period of time or over too large a geographic area or by reason of it being too extensive in any other respect or for any other reason, it will be interpreted to extend only over the longest period of time for which it may be enforceable and/or over the largest geographic area as to which it may be enforceable and/or to the maximum extent in all other aspects as to which it may be enforceable, all as determined by such court or arbitrator. (c) Customer Lists, Non-Solicitation. In consideration of the benefits of this Agreement to Sellers and Shareholder and as a material inducement to Purchaser to enter into this Agreement and to pay the Purchase Price, Sellers and Shareholder hereby further covenant and agree that for a period of five years following the Closing Date, Sellers and Shareholder shall not, and each shall cause their Affiliates not to, directly or indirectly, (a) use or make known to any person or entity the names or addresses of any clients or customers of either of Sellers, Purchaser or any Affiliate of Purchaser or any other information pertaining to them, (b) call on, solicit, take away or attempt to call on, solicit or take away any clients or customers of either of Sellers, Purchaser or any Affiliate of Purchaser, or (c) solicit for employment, recruit, hire or attempt to recruit or hire any employees of either of Sellers, Purchaser or any Affiliate of Purchaser. (d) Equitable Relief. In the event of a breach or a threatened breach by Shareholder or either of Sellers of any of the provisions contained in this Section 12.8, each acknowledges that Purchaser and its Affiliates will suffer irreparable injury not fully compensable by money damages and, therefore, will not have an adequate remedy available at law. Accordingly, Purchaser shall be entitled, without the necessity of posting a bond, to obtain such injunctive relief or other equitable remedy from any court of competent jurisdiction as may be necessary or appropriate to prevent or curtail any such breach, threatened or actual. The foregoing shall be in addition to and without prejudice to any other rights that Purchaser may have under this Agreement, at law or in equity, including, without limitation, the right to sue for damages. (e) Covenants Independent. The covenants of Sellers and Shareholder contained in this Section 12.8 will be construed as independent of any other provision in this Agreement, and the existence of any claim or cause of action by Sellers or Shareholder, or any of them, against Purchaser or any Affiliate of Purchaser will not constitute a defense to the enforcement by Purchaser of said provisions. Sellers and Shareholder understand that the provisions contained in this Section 12.8 are essential elements of the transactions contemplated by this Agreement and, but for their agreement to be bound by the provisions of this Section 12.8, Purchaser would not have agreed to enter into this Agreement and the transactions contemplated herein. Each of Sellers and Shareholder has been advised to 39

47 consult with, and represents that it or he has consulted with, counsel in order to be informed in all respects concerning the reasonableness and propriety of the provisions of this Section 12.8 and each acknowledges that the provisions of this Section 12.8 are reasonable in all respects. 12.9 Agreement Regarding GMC Excluded Assets. If as of the date that is six months after the Closing Date, Purchaser has not entered into a dealer sales and service agreement with GMC, the GMC Excluded Assets have not been sold pursuant to the GMC Operating Agreement and Sellers are not able to transfer the GMC Excluded Assets to GMC or an Affiliate of GMC, Purchaser will purchase the GMC Excluded Assets from Sellers and Sellers shall sell the GMC Excluded Assets to Purchaser for the price indicated for such items in Section 3.1. The closing for such sale and purchase shall take place at a date and time that is mutually agreeable to the parties, which shall be no more than 30 days after Sellers provide Purchaser written notice that Sellers are not able to transfer the GMC Excluded Assets to GMC or an Affiliate of GMC. Sellers, at their sole cost and expense, shall provide all documentation and evidence reasonably requested by Purchaser to enable Purchaser to verify that the conditions to Purchaser's purchase obligations hereunder have been satisfied. At such closing, Purchaser shall pay the amount due Sellers by wire transfer of immediately available funds to an account jointly designated by Sellers. 13. INDEMNITY BY SELLERS AND SHAREHOLDER. 13.1 Indemnity. Sellers and Shareholder (collectively, the "Seller Indemnifying Parties", and individually, a "Seller Indemnifying Party") shall, and hereby do, jointly and severally indemnify, hold harmless and defend Purchaser and its officers, directors, employees, agents, consultants, representatives and Affiliates (collectively, the "Purchaser Indemnified Parties") from and against any and all penalties, demands, damages, punitive damages, losses, liabilities, suits, costs, costs of any settlement or judgment, claims of any and every kind whatsoever, refund obligations (including, without limitation, interest and penalties thereon) and remediation costs and expenses (including, without limitation, reasonable attorneys' fees), of or to any of the Purchaser Indemnified Parties ("Purchaser Damages"), which may now or in the future be paid, incurred or suffered by or asserted against the Purchaser Indemnified Parties by any Person resulting or arising from or incurred in connection with any one or more of the following (provided that this Section 13.1 shall not apply to any items that have been expressly assumed by Purchaser under this Agreement): (a) any liability or claim for liability (whether in contract, in tort or otherwise, and whether or not successful) related in any way to the Assets or the Business to the extent such liability or claim for liability arises in connection with any action, omission or event occurring on or prior to the Closing Date (including, but not limited to, claims for product liability with respect to products manufactured, distributed or sold by either Seller on or prior to the Closing Date); (b) any liability or claim for liability (whether in contract, in tort or otherwise, and whether or not successful) related to any liens, obligations or encumbrances of any nature 40

48 whatsoever against or in any way related to the Assets or the Business which have not been expressly assumed by Purchaser hereunder; (c) any liability or claim for liability (whether in contract, in tort or otherwise, and whether or not successful) related to Taxes of either Seller; (d) any liability or claim for liability (whether or not successful) related to any lawsuit or threatened lawsuit or claim involving any Seller Indemnifying Party other than claims brought by any Seller Indemnifying Parties pursuant to Article 14; (e) any misrepresentation, breach of warranty or nonfulfillment of any covenant or agreement on the part of a Seller Indemnifying Party under this Agreement or from any misrepresentation in or omission from any Schedule, the Seller Certificate or the exhibits and annexes hereto; (f) any liability or claim for liability against Purchaser or any of the Assets to the extent such liability or claim for liability arises in connection with the failure of Purchaser and Sellers to comply with any applicable bulk transfer law; and (g) all actions, suits, proceedings, demands, assessments, adjustments, costs and expenses (including costs of court and reasonable attorneys' fees) incident to any of the foregoing. 13.2 Environmental Liability of the Seller Indemnifying Parties. Notwithstanding anything herein to the contrary, the Seller Indemnifying Parties shall have no liability or obligation to indemnify hereunder for any Purchaser Environmental Liabilities arising from acts, events or omissions occurring prior to either of Sellers' operation of the Business on any real property owned, leased or used by either of Sellers or any environmental condition or liability disclosed on the Disclosure Schedule. The Seller Indemnifying Parties, jointly and severally, shall retain liability for, and the Seller Indemnifying Parties, jointly and severally, shall indemnify, hold harmless and defend the Purchaser Indemnified Parties from and against all claims (whether in contract, in tort or otherwise, and whether or not successful), fines, penalties, liabilities, damages and losses, including but not limited to remedial, removal, response, abatement, clean-up, investigation and monitoring costs and any other related costs and expenses incurred (whether any claims or causes of action relating thereto be asserted in common law or under statute and regardless of form including strict liability and negligence) (collectively referred to as "Purchaser Environmental Liabilities") arising from (a) any violation of any Requirement of Environmental Law or Environmental Permits (as those terms are hereinafter defined) of any Seller Indemnifying Party occurring or existing between the date either Seller began conducting business on each parcel of real estate owned, leased or used by either Seller and the Closing Date, (b) any acts, omissions, conditions, facts, or circumstances occurring or existing between the date either Seller began conducting business on each parcel of real estate owned, leased or used by either Seller and the Closing Date with respect to the Assets, the Business or the operations of Sellers which give rise to an Environmental Claim (as hereinafter defined) before or 41

49 after the date hereof, and (c) any failure of any Seller Indemnifying Party to obtain or maintain, between the date either Seller began conducting business on each parcel of real estate owned, leased or used by either Seller and the Closing Date, any Environmental Permit. For purposes of this Section 13.2, the term "Environmental Claim" means any action, lawsuit, claim or proceeding by any Person relating to the Assets or the Business or the operations or the business of either Seller which seeks to impose liability for (i) noise, (ii) pollution or contamination or threatened pollution or contamination of the air, surface water, groundwater or land, (iii) solid, gaseous or liquid waste generation, handling, treatment, storage, disposal or transportation, (iv) exposure to hazardous or toxic substances or (v) non-compliance with any Requirement of Environmental Law. An "Environmental Claim" includes, without limitation, a proceeding to terminate a permit or license to the extent that such a proceeding attempts to redress violations of the applicable permit or license or any Requirement of Environmental Law as alleged by any Governmental Authority. For purposes of this Section 13.2, the term "Environmental Permit" means any permit, license, approval or other authorization related to, used in connection with or necessary for the operation or use of the Business or the Assets, or the operations or the businesses of either Seller under any applicable Requirement of Environmental Law.

Purchaser agrees that upon its discovery of facts giving rise to a claim for indemnity under the provisions of this Agreement, including receipt by it or any Purchaser Indemnified Party of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise, by any Person with respect to any matter as to which any of the Purchaser Indemnified Parties are entitled to indemnity under the provisions of this Agreement (such actions being collectively referred to herein as a "Purchaser Claim"), Purchaser will give prompt notice thereof in writing to the Seller Indemnifying Parties together with a statement of such information respecting any of the foregoing as it shall then have; provided that any delay in giving or failure to give such notice shall not limit the rights of Purchaser or any Purchaser Indemnified Party to indemnity hereunder except in accordance with the time limitations provided in Section 13.10 and to the extent that the Seller Indemnifying Parties are shown to have been damaged by such delay or failure. 13.4 Right of the Seller Indemnifying Parties to Participate in Defense. With respect to any Purchaser Claim as to which any of the Purchaser Indemnified Parties seeks indemnity hereunder, Purchaser shall provide the Seller Indemnifying Parties with the opportunity to participate in the defense of such Purchaser Claim with counsel of the Seller Indemnifying Parties' choice and at the Seller Indemnifying Parties' cost and expense and shall not, without the consent of Shareholder, which consent shall not be unreasonably withheld, settle any such Purchaser Claim, so long as the Seller Indemnifying Parties shall have unconditionally acknowledged their obligation to indemnify hereunder with respect to such Purchaser Claim. To the extent reasonably requested by Purchaser, 42

50 the Seller Indemnifying Parties shall reasonably cooperate with Purchaser and its representatives and counsel in any dispute or defense related to any Purchaser Claim. 13.5 Payment. The Seller Indemnifying Parties shall promptly pay to Purchaser or such other Purchaser Indemnified Party as may be entitled to indemnity hereunder in cash by wire transfer the amount of any Purchaser Damages to which Purchaser or such Purchaser Indemnified Party may become entitled by reason of the provisions of this Agreement. 13.6 Limit of Liability of the Seller Indemnifying Parties. Notwithstanding any other provisions of this Agreement, the aggregate liability of the Seller Indemnifying Parties under this Agreement and the New Mexico Purchase Agreement, whether as a party to this Agreement or as guarantor of Sellers' obligations under this Agreement or the New Mexico Purchase Agreement, shall be limited to $3,000,000, except that such limit shall be $5,000,000 for breach of the representations and warranties set forth in Sections 4.6, 4.16 and 4.17 or any indemnification claim under this Agreement relating to environmental matters. 13.7 Limitations on Indemnification. Notwithstanding any provision of this Agreement, the Seller Indemnifying Parties shall not be liable for any matter that could be made the subject of a claim under this Article 13 or under Article 13 of the New Mexico Purchase Agreement regarding any claims, losses, expenses or other liabilities until the aggregate amount thereof exceeds $250,000 and after such threshold amount has been attained, all claims, other than those aggregated to reach the threshold, shall be indemnified hereunder. 13.8 Insurance and Refunds. The Seller Indemnifying Parties' indemnification obligations shall be reduced to the extent that the subject matter of the claim is covered by and paid to Purchaser or its Affiliates pursuant to a warranty or indemnification from a third party or third party insurance. The amount of indemnification due from the Seller Indemnifying Parties with respect to any claim shall be reduced by the effect of any tax deduction, credit, refund or other tax benefit to Purchaser or it Affiliates relating to the same tax period and resulting from the subject matter of that claim and such indemnification. 13.9 Offset Provisions. Notwithstanding any other provisions of this Agreement, in the event, between the Closing Date and the date the Bonus Payment is paid, the Seller Indemnifying Parties become obligated to pay sums to Purchaser or any Purchaser Indemnified Party under this Agreement or any of the documents or agreements referenced herein or contemplated hereby (whether as a result of indemnity, breach of contract or otherwise), Purchaser shall have the right to and shall be obligated to reduce and offset payments due on the Bonus Payment in such amount or amounts as Purchaser (and any Purchaser Indemnified Party that is not promptly paid by the Seller Indemnifying Parties) is entitled to receive from the Seller Indemnifying Parties, and any such offset shall be deemed to be a payment of the Bonus Payment to the extent of such offset; provided, however, that any such offset shall not relieve the Seller Indemnifying Parties from paying all amounts that are due in excess of the amount offset. Prior to any offset under this Section 13.9, Purchaser 43

51 shall have provided to the Seller Indemnifying Parties a notice of Purchaser Claim as described in Section 13.3 or an otherwise reasonably detailed description of the matter giving rise to such offset. 13.10 Time Limits for Indemnity Claims. Any claim for indemnification under this Article 13 must be made within the time periods set forth in Article 6. 14. INDEMNITY BY PURCHASER. 14.1 Indemnity.

52 defined) during the time Purchaser is the owner of the Assets and the operator of the Business, and (c) any failure of Sellers or Shareholder to obtain or maintain after the Closing Date, any Environmental Permit. For purposes of this Section 14.2, the term "Environmental Claim" means any action, lawsuit, claim or proceeding by any Person relating to the Assets or the Business or the operations or the Business which seeks to impose liability for (i) noise, (ii) pollution or contamination or threatened pollution or contamination of the air, surface water, groundwater or land, (iii) solid, gaseous or liquid waste generation, handling, treatment, storage, disposal or transportation, (iv) exposure to hazardous or toxic substances or (v) non-compliance with any Requirement of Environmental Law.

For purposes of this Section 14.2, the term "Environmental Permit" means any permit, license, approval or other authorization related to, used in connection with or necessary for the operation or use the Business or the Assets, or the operations or the Business under any applicable Requirement of Environmental Law.

Sellers and Shareholder agree that upon their discovery of facts giving rise to a claim for indemnity under the provisions of this Agreement, including receipt by Sellers or Shareholder of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise, by any Person with respect to any matter as to which Sellers or Shareholder are entitled to indemnity under the provisions of this Agreement (such actions being collectively referred to herein as a "Seller Claim"), Sellers and Shareholder will give prompt notice thereof in writing to Purchaser together with a statement of such information respecting any of the foregoing as they shall then have; provided that any delay in giving or failure to give such notice shall not limit the rights of Sellers or Shareholder to indemnity hereunder except to the extent that Purchaser is shown to have been damaged by such delay or failure. 14.4 Right of Purchaser to Participate in Defense. With respect to any Seller Claim as to which Sellers or Shareholder seeks indemnity hereunder, Sellers and Shareholder shall provide Purchaser with the opportunity to participate in the defense of such Seller Claim with counsel of Purchaser's choice and at Purchaser's cost and expense. To the extent reasonably requested by Sellers and Shareholder, Purchaser shall reasonably cooperate with Sellers and Shareholder and their representatives and counsel in any dispute or defense related to any Seller Claim. 45

Notwithstanding any provision of this Agreement, Purchaser shall not be liable for any matter that could be made the subject of a claim under this Article 14 and Article 14 of the New Mexico Purchase Agreement regarding any claims, losses, expenses or other liabilities until the aggregate amount thereof exceeds $250,000 and after such threshold amount has been attained, all claims, other than those aggregated to reach the threshold, shall be indemnified hereunder. 14.7 Insurance and Refunds. Purchaser's indemnification obligations shall be reduced to the extent that the subject matter of the claim is covered by and paid to Sellers or their Affiliates pursuant to a warranty or indemnification from a third party or third party insurance. The amount of indemnification due from Purchaser with respect to any claim shall be reduced by the effect of any tax deduction, credit, refund or other tax benefit to either of Sellers or their Affiliates relating to the same tax period and resulting from the subject matter of that claim and such indemnification. 15.

55 16. SPECIAL PROVISIONS REGARDING EMPLOYEES OF SELLERS. 16.1 New Employees of Purchaser. It is the intention of Purchaser, and Sellers hereby acknowledge and agree with such position, that any employees of Sellers that Purchaser hires will be new employees of Purchaser as of the Closing Date or the date of hire, which ever is later. Such new employees shall be entitled only to such compensation and employee benefits as are agreed to by such employees and Purchaser, or as are otherwise provided by Purchaser, in its sole discretion. 16.2 No Hiring Commitment. Purchaser specifically does not commit to hire any of the employees of the Business, and Sellers specifically understand and acknowledge this fact. However, notwithstanding Purchaser's position, Purchaser will review its needs in anticipation of the purchase of the Assets with a view to hiring certain of the employees of Sellers as of the Closing Date. In its review, Purchaser expects to be able to review employee records and conduct employee interviews. Sellers agree that after the date hereof they will make, on a confidential basis, their respective employee records available to Purchaser and permit Purchaser to contact their respective employees for the purpose of conducting employee interviews. Sellers further agree to make employees designated by Purchaser available to Purchaser for such purpose. 16.3 Existing Employee Benefit Plans; Assumption of Vacation and Sick Leave Obligations. At the Closing, Purchaser shall assume Sellers' obligations to employees of Sellers hired by Purchaser for accrued but unused vacation and sick leave, and the Purchase Price shall be reduced by the dollar value of such obligation. Except for vacation and sick leave time assumed by Purchaser as set forth above, Purchaser shall have no obligation after the Closing to continue any pension plans or work benefit plans currently offered by Sellers to their employees. Except for vacation and sick leave time assumed by Purchaser as set forth above, Sellers and Shareholder jointly and severally agree to indemnify and hold harmless Purchaser from and against any claim which may arise because of the failure to continue such pension plans or work benefit programs. 17.

This Agreement will automatically terminate on December 1, 1999, if the Closing shall not have occurred on or before such date, unless the parties shall have otherwise agreed in writing prior to such date. No party will be liable in damages to any other party as a result 48

56 of termination pursuant to this Article 17 unless the failure of the Closing was due to the failure of such party to comply with the terms of this Agreement. 18. NOTICES.

To the Best Knowledge of Seller and Shareholder there is no reason why any of the Contracts (i) will result in a loss to Purchaser on completion by performance or (ii) cannot readily be fulfilled or performed by Purchaser with the Assets on time without undue or unusual expenditure of money or effort.

Seller and Shareholder agree that they will not disclose, and they will use their best efforts to prevent disclosure by any other Person of, any such confidential information to, nor any discussion of any of the terms of this Agreement with, any Person for any purpose or reason whatsoever, except to authorized representatives of Purchaser. Seller and Shareholder recognize and agree that violation of any of the agreements contained in this Section 12.6(a) will cause irreparable damage or injury to Purchaser, the exact amount of which may be impossible to ascertain, and that, for such reason, among others, Purchaser shall be entitled to an injunction, without the necessity of posting bond therefor, restraining any further violation of such agreements.

In the event any confidential information protected by this Section 12.6 is required to be disclosed under court or governmental order, 33

40 rule or regulation, the party required to disclose such confidential information shall immediately provide the party entitled to protection hereunder with notice thereof and shall give full and complete cooperation to such party in its efforts to object to, and to obtain protection of any confidential information that is the subject of, such required disclosure. 12.7 Assignment of Contracts. Notwithstanding any other provision of this Agreement, nothing in this Agreement or any related document shall be construed as an attempt to assign (i) any Contract which, as a matter of law or by its terms, is nonassignable without the consent of the other parties thereto unless such consent has been given, or (ii) any Contract or claim as to which all of the remedies for the enforcement thereof enjoyed by Seller would not, as a matter of law or by its terms, pass to Purchaser as an incident of the transfers and assignments to be made under this Agreement. In order, however, that the full value of every Contract and claim of the character described in clauses (i) and (ii) above and all claims and demands on such Contracts may be realized for the benefit of Purchaser, Seller, at the request and expense and under the direction of Purchaser, shall take all such action and do or cause to be done all such things as will, in the opinion of Purchaser, be necessary or proper in order that the obligations of Seller under such Contracts may be performed in such manner that the value of such Contract will be preserved and will inure to the benefit of Purchaser, and for, and to facilitate, the collection of the moneys due and payable and to become due and payable thereunder to Purchaser in and under every such contract and claim. Seller shall promptly pay over to Purchaser all moneys collected by or paid to it in respect of every such contract, claim or demand. Nothing in this Section 12.7 shall relieve Seller or Shareholder of their obligations to obtain any consents required for the transfer of the Assets and all rights thereunder to Purchaser, or shall relieve Seller or Shareholder from any liability to Purchaser for failure to obtain such consents. 12.8 Non-Compete, Non-Solicitation. (a) Non-Competition. In consideration of the benefits of this Agreement to Seller and Shareholder and as a material inducement to Purchaser to enter into this Agreement and to pay the Purchase Price, Seller and Shareholder, hereby covenant and agree that for a period of five years after the Closing Date, Seller and Shareholder shall not, and each shall cause their Affiliates (not including any family member of Shareholder) not to, directly or indirectly, as proprietor, partner, stockholder, director, officer, employee, consultant, joint venturer, investor or in any other capacity, engage in, or own, manage, operate or control, or participate in the ownership, management, operation or control, of any entity which engages in the sale, servicing, renting, leasing, insuring or financing of new or used Class 3 through 8 trucks (not including construction equipment) in any geographical or commercial markets in which Rush or any of its Affiliates (including Purchaser) conducts such business on the Closing Date; provided, however, the foregoing shall not, in any event, prohibit Seller or Shareholder from (i) purchasing and holding as an investment not more than 1% of any class of publicly traded securities of any entity which conducts such business, so long as neither Seller nor Shareholder participates in any way in the management, operation or 34

41 control of such entity or (ii) selling or otherwise disposing of any vehicles, parts and accessories inventory or chassis kits held by the Business as of the Closing Date that are not transferred to Purchaser pursuant to the terms of this Agreement. It is further recognized and agreed that, even though the activity may not be restricted under the foregoing provision, for a period of five years following the Closing Date, neither Seller nor Shareholder shall, and each shall cause their Affiliates not to, provide any services to any person or entity which may be used against, or in conflict with the interests of, Purchaser or an Affiliate of Purchaser. (b) Judicial Reformation. Seller and Shareholder acknowledge that, given the nature of Purchaser and its Affiliates' business, the covenants contained in this Section 12.8 establish reasonable limitations as to time, geographic area and scope of activity to be restrained and do not impose a greater restraint than is reasonably necessary to protect and preserve the goodwill of Purchaser and its Affiliates' business and to protect their legitimate business interests. If, however, this Section 12.8 is determined by any court of competent jurisdiction or an arbitrator pursuant to Section 20.1 to be unenforceable by reason of it extending for too long a period of time or over too large a geographic area or by reason of it being too extensive in any other respect or for any other reason, it will be interpreted to extend only over the longest period of time for which it may be enforceable and/or over the largest geographic area as to which it may be enforceable and/or to the maximum extent in all other aspects as to which it may be enforceable, all as determined by such court or arbitrator. (c) Customer Lists, Non-Solicitation. In consideration of the benefits of this Agreement to Seller and Shareholder and as a material inducement to Purchaser to enter into this Agreement and to pay the Purchase Price, Seller and Shareholder hereby further covenant and agree that for a period of five years following the Closing Date, Seller and Shareholder shall not, and each shall cause their Affiliates not to, directly or indirectly, (a) use or make known to any person or entity the names or addresses of any clients or customers of Seller, Purchaser or any Affiliate of Purchaser or any other information pertaining to them, (b) call on, solicit, take away or attempt to call on, solicit or take away any clients or customers of Seller, Purchaser or any Affiliate of Purchaser, or (c) solicit for employment, recruit, hire or attempt to recruit or hire any employees of Seller, Purchaser or any Affiliate of Purchaser. (d) Equitable Relief. In the event of a breach or a threatened breach by Shareholder or Seller of any of the provisions contained in this Section 12.8, each acknowledges that Purchaser and its Affiliates will suffer irreparable injury not fully compensable by money damages and, therefore, will not have an adequate remedy available at law. Accordingly, Purchaser shall be entitled, without the necessity of posting a bond, to obtain such injunctive relief or other equitable remedy from any court of competent jurisdiction as may be necessary or appropriate to prevent or curtail any such breach, 35

42 threatened or actual. The foregoing shall be in addition to and without prejudice to any other rights that Purchaser may have under this Agreement, at law or in equity, including, without limitation, the right to sue for damages. (e) Covenants Independent. The covenants of Seller and Shareholder contained in this Section 12.8 will be construed as independent of any other provision in this Agreement, and the existence of any claim or cause of action by Seller or Shareholder, or any of them, against Purchaser or any Affiliate of Purchaser will not constitute a defense to the enforcement by Purchaser of said provisions. Seller and Shareholder understand that the provisions contained in this Section 12.8 are essential elements of the transactions contemplated by this Agreement and, but for their agreement to be bound by the provisions of this Section 12.8, Purchaser would not have agreed to enter into this Agreement and the transactions contemplated herein. Seller and Shareholder have each been advised to consult with, and each represents that it or he has consulted with, counsel in order to be informed in all respects concerning the reasonableness and propriety of the provisions of this Section 12.8 and each acknowledges that the provisions of this Section 12.8 are reasonable in all respects. 12.9 Agreement Regarding GMC Excluded Assets.

The closing for such sale and purchase shall take place at a date and time that is mutually agreeable to the parties, which shall be no more than 30 days after Seller provides Purchaser written notice that Seller is not able to transfer the GMC Excluded Assets to GMC or an Affiliate of GMC. Seller, at its sole cost and expense, shall provide all documentation and evidence reasonably requested by Purchaser to enable Purchaser to verify that the conditions to Purchaser's purchase obligations hereunder have been satisfied. At such closing, Purchaser shall pay the amount due Seller by wire transfer of immediately available funds to an account designated by Seller. 13. INDEMNITY BY SELLER AND SHAREHOLDER. 13.1 Indemnity.

SPECIAL PROVISIONS REGARDING EMPLOYEES OF SELLER. 16.1 New Employees of Purchaser.

(j) Selling Expenses. "Selling Expenses" shall mean all underwriting discounts, selling commissions and stock transfer taxes applicable to the securities registered by Holders and all attorneys' fees and expenses of counsel for Holders. 2. COMPANY REGISTRATION (a) Notice of Registration. If at any time or from time to time after the date hereof Company shall determine to register any of its securities, either for its own account or the account of Other Holders, other than (i) a registration relating solely to employee benefit plans or (ii) a registration relating solely to a Commission Rule 145 transaction, Company will: (i) give prompt (and in any event within twenty (20) days before the anticipated filing date of the related registration statement) written notice thereof to each Holder indicating the proposed offering price and describing the plan of distribution; and (ii) include in such registration and, at the request of any Holder, in any underwriting involved therein, all the Registrable Securities specified in a written request by any Holder to Company, made within twenty (20) days after receipt of such written notice from Company. (b) Election Revocable. If, prior to the execution by a Holder of the underwriting agreement contemplated by Subsection 2(c), such Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to Company and the managing underwriter. Any securities excluded or withdrawn from such underwriting also shall be withdrawn from such registration, and shall not be transferred in a public distribution prior to ninety (90) days after the effective date of the registration statement relating thereto, or such other shorter period of time as the underwriters may require. (c) Underwriting. If the registration of which Company gives notice is for a registered public offering involving an underwriting, Company shall so advise Holders. In such event, the right of any Holder to registration pursuant to this Section 2 shall be conditioned upon such Holder's participation in such underwriting and the inclusion of Registrable Securities in the underwriting to the extent provided in this Section 2. All Holders proposing to distribute their securities through such underwriting shall, together with Company, enter into an underwriting agreement in customary form with the -3-

4 managing underwriter selected for such underwriting by Company. Company may exclude from such underwriting the Registrable Securities of any Holder who does not accept the terms agreed upon between Company and the underwriters. Company shall use its reasonable best efforts to cause the managing underwriter of such proposed underwritten offering to permit the Registrable Securities proposed to be included in such registration to be included in the registration statement for such offering on the same terms and conditions as any similar securities of Company included therein. Notwithstanding any other provision of this Section 2, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter may limit the Registrable Securities to be included in such registration. In such event, Company shall so advise Holders, and the number of shares that may be included in the registration and underwriting by Holders and Other Holders shall be allocated among all Holders and all Other Holders in proportion, as nearly as practicable, to the respective amounts of Common Stock held by such Holders and Other Holders at the time of filing of the registration statement. To facilitate the allocation of shares in accordance with the above provisions, Company may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. (d) Right to Terminate Registration. Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2 prior to the effectiveness of such registration whether or not any Holder has elected to include Registrable Securities in such registration. 3. REGISTRATION ON FORM S-3 (a) Request for Registration. If any Holder holding or Holders in the aggregate holding 100,000 or more Registrable Securities requests that Company file a registration statement on Form S-3 (or any successor form to Form S-3) for a public offering of shares of 100,000 or more Registrable Securities, and Company is a registrant entitled to use Form S-3 to register the Registrable Securities for such an offering, Company shall use its best efforts to cause such Registrable Securities requested by Holders to be included in such registration to be registered for the offering on such form and to cause such Registrable Securities to be qualified in such jurisdictions as Holders may reasonably request. (b) Limitations. Notwithstanding the foregoing, Company shall not be obligated to take any action pursuant to this Section 3: (i) in any particular jurisdiction in which Company would be required to execute a general consent to service of process in effecting such registration, qualification or compliance unless Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; (ii) If Company, within ten (10) days of the receipt of the request of Holders requesting registration under this Section 3, gives notice of its bona fide -4-

5 intention to effect the filing of a registration statement with the Commission within ninety (90) days of receipt of such request (other than with respect to a registration statement relating to a Rule 145 transaction, an offering solely to employees or any other registration which is not appropriate for the registration of Registrable Securities); (iii) during the period starting with the date thirty (30) days prior to Company's good faith estimated date of filing of, and ending on the date six (6) months immediately following, the effective date of any registration statement pertaining to securities of Company (other than a registration of securities in a Rule 145 transaction or with respect to an employee benefit plan), provided that Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective; (iv) if Company shall furnish to such Holder a certificate signed by the Chief Executive Officer of Company stating that in the good faith judgment of Company's Board of Directors the filing of a registration statement would require the disclosure of material information that Company has a bona fide business purpose for preserving as confidential and that is not then otherwise required to be disclosed or it would be seriously detrimental to Company and its shareholders for such Form S-3 to be effected at such time, then Company's obligation to use its best efforts to file a registration statement shall be deferred for a period not to exceed one hundred twenty (120) days from the receipt of the request to file such registration by such Holder, provided, however, that Company shall not utilize this right more than once in any twelve (12) month period; or (v) after Company has effected one (1) registration pursuant to this Section 3, and such registration has been declared or ordered effective and has been available to Holders for resale for a period of at least six consecutive months. 4. COMPANY'S PURCHASE OBLIGATION The next time Company has a registration statement ordered or declared effective (which shall include the Form S-1 Company anticipates filing the fourth quarter of 1999 for a public offering of approximately 2,000,000 shares of Common Stock, whether or not such Form S-1 is ordered or declared effective before or after the date hereof) (an "Offering"), Company shall have the obligation to acquire all Registrable Securities held by Holders at such time and each Holder shall be obligated to sell such Registrable Securities to Company. Company shall give each Holder written notice of the effectiveness of the registration statement on or before the later of three business days after Company receives the proceeds for the Offering or three business days from the date hereof. The closing of such purchase shall take place at a time mutually agreed to by the parties thereto, which shall be no later than five business days after Company gives the notice described above. The purchase price payable to each Holder for the Registrable Securities held by such Holder shall be equal to (i) the -5-

6 number of shares of Common Stock purchased from such Holder pursuant to this Section 4 multiplied by the greater of (a) $16.875 and (b) the price per share the Common Stock is sold to the public in the Offering less Holder's pro rata share of all commissions charged in connection with the Offering. At the closing, Company shall pay to each Holder the purchase price due such Holder in cash by wire transfer against delivery of certificate(s) representing the Registrable Securities Company is purchasing from such Holder, duly endorsed in blank or accompanied by a duly executed stock power in blank, to effect the transfer of the Registrable Securities to Company. The Registrable Securities being purchased by Company shall be conveyed and delivered to Company free and clear of all liens, security interests, encumbrances, options, calls or other restrictions. Any assignment of Registrable Securities by a Holder shall be made expressly subject to the provisions of this Section 4. Company shall have the absolute right to terminate or withdraw any registration statement prior to the effectiveness of such registration statement without any liability. 5. OBLIGATIONS OF COMPANY Whenever required under this Agreement to effect the registration of any Registrable Securities, Company shall, as expeditiously as reasonably possible: (a) Prepare and file with the Commission a registration statement with respect to such Registrable Securities, use its best efforts to cause such registration statement to become effective, and, upon the request of Holders, keep such registration statement effective for up to ninety (90) days. (b) Prepare and file with the Commission 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 Securities Act with respect to the disposition of all securities covered by such registration statement. (c) Furnish to Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of all securities covered by such registration statement. (d) Use its commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or blue sky laws of such jurisdictions as shall be reasonably requested by Holders, provided that 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 states or jurisdictions. (e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement. -6-

7 (f) Notify each Holder of Registrable Securities covered by such registration statement, at any time when a prospectus relating thereto covered by such registration statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an 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 not misleading in the light of the circumstances then existing. (g) At the request of any Holder requesting registration of Registrable Securities pursuant to this Agreement, furnish on the date that such Registrable Securities are delivered to the underwriters for sale in connection with a registration pursuant to this Agreement (i) an opinion, dated such date, of the counsel representing Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters and (ii) a letter dated such date, from the independent certified public accountants of Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters. (h) List the Registrable Securities being registered on any national securities exchange on which a class of Company's equity securities are listed or qualify the Registrable Securities being registered for inclusion on Nasdaq if Company does not have a class of equity securities listed on a national securities exchange. 6. OBLIGATIONS OF HOLDERS It shall be a condition precedent to the obligations of Company to take any action pursuant to this Agreement that Holders who have requested the registration of Registrable Securities: (a) Furnish to Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be reasonably requested by Company or reasonably required to effect the registration of the Registrable Securities; (b) Cooperate in good faith with Company and the underwriters, if any, in connection with such registration, including executing any documents in connection with such registration as Company or the underwriters may reasonably request and placing the Registrable Securities in escrow or custody to facilitate the sale and distribution thereof; and (c) Make no further sales or other dispositions, or offers therefor, of the Registrable Securities under such registration statement if, during the effectiveness of such registration statement, an intervening event should occur which, in the opinion of counsel to Company, makes the prospectus included in such registration statement no longer comply with the Securities Act, so long as written notice containing the facts and legal conclusions -7-

8 relied upon by Company in this regard has been received by Holders from Company, until such time as Holders have received from Company copies of a new, amended or supplemented prospectus complying with the Securities Act, which prospectus shall be delivered to Holders by Company as soon as practicable after such notice. 7. CONFIDENTIALITY OF COMPANY INFORMATION Each Holder agrees that it will keep confidential and will not disclose or divulge or otherwise misuse any confidential, proprietary or secret information which such Holder may obtain from Company unless such information is or becomes known to such Holder from a source other than Company without violation of any rights of Company, or is or becomes publicly known, or unless Company gives its written consent to such Holder's release of such information, except that no such written consent shall be required (and such Holder shall be free to release such information to such recipient) if such information is to be provided to such Holder's counsel or accountant (and the provision of such information is directly necessary in order for such recipient to provide services to such Holder), or to an officer, director, member or partner of such Holder, provided that such Holder shall inform the recipient of the confidential nature of such information, and such recipient agrees in writing in advance of disclosure to treat the information as confidential. 8. EXPENSES OF REGISTRATION (a) Registration Expenses. Company shall bear all Registration Expenses incurred in connection with all registrations pursuant to Sections 2 and 3 hereof. (b) Selling Expenses. All Selling Expenses relating to securities registered on behalf of Holders shall be borne by Holders pro rata on the basis of the number of Registrable Securities so registered. 9. DELAY OF REGISTRATION No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any registration of Company as the result of any controversy that might arise with respect to the interpretation or implementation of this Agreement. 10. INDEMNIFICATION (a) By Company. Company will indemnify each Holder, each of its officers and directors, partners, employees and agents, and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance has ben effected pursuant to this Agreement, and each underwriter, if any, and each person who controls any underwriter within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or -8-

9 threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained (or incorporated by reference) in any registration statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation by Company of the Securities Act or any rule or regulation promulgated under the Securities Act applicable to Company in connection with any such registration, qualification or compliance, and Company will reimburse each such Holder, each of its officers, directors, partners, employees and agents, and each person controlling such Holder, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, provided that Company will not be liable to any such Holder, controlling person or underwriter in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission, or alleged untrue statement or omission, made or incorporated by reference in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to Company by an instrument duly executed by any Holder, controlling person or underwriter and stated to be specifically for use therein. If Holders are represented by counsel other than counsel for Company, Company will not be obligated under this Section 10(a) to reimburse legal fees and expenses of more than one separate counsel for Holders. (b) By Holders. Each Holder will indemnify Company, each of its directors, officers, each underwriter, if any, of Company's securities covered by such a registration statement, each person who controls Company or such underwriter within the meaning of Section 15 of the Securities Act, and each other Holder, each of its officers, directors, partners, employees and agents and each person controlling such Holders within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained (or incorporated by reference) in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse Company, such Holders, such directors, officers, partners, employees and agents, underwriters or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made (or incorporated by reference) in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to Company by an instrument duly executed by such Holder and stated to be specifically for use therein. -9-

10 (c) Procedure for Indemnification. Each party entitled to indemnification under paragraph (a) or (b) of this Section 10 (the "Indemnified Party") shall, promptly after receipt of notice of any claim or the commencement of any action against such Indemnified Party in respect of which indemnity may be sought, notify the party required to provide indemnification (the "Indemnifying Party") in writing of the claim or the commencement thereof; provided that the failure of the Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which it may have to an Indemnified Party pursuant to the provisions of this Section 10, unless the Indemnifying Party was materially prejudiced by such failure, and in no event shall such failure relieve the Indemnifying Party from any other liability which it may have to such Indemnified Party. If any such claim or action shall be brought against an Indemnified Party, it shall notify the Indemnifying Party thereof and provide the Indemnifying Party with the opportunity to participate in the defense of such claim or action with counsel of the Indemnifying Party's choice and at the Indemnifying Party's cost and expense and shall not, without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld, settle any claim or action, so long as the Indemnifying Party shall have unconditionally acknowledged its obligation to indemnify hereunder with respect to such claim or action. To the extent reasonably requested by the Indemnified Party, the Indemnifying Party shall reasonably cooperate with the Indemnified Party and its representatives and counsel in any dispute or defense related to any claim or action. The Indemnifying Party shall promptly pay to the Indemnified Party in cash the amount to which such Indemnified Party may become entitled by reason of the provisions of this Section 10. (d) Contribution. If the indemnification provided for in this Section 10 shall for any reason be unavailable to an Indemnified Party in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to herein, then each Indemnifying Party shall, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as shall be appropriate to reflect the relative fault of the Indemnifying Party on the one hand and the Indemnified Party on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Indemnifying Party on the one hand or the Indemnified Party on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission, but not by reference to any Indemnified Party's stock ownership in Company. The amount paid or payable by an Indemnified Party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this paragraph shall be deemed to include, for purposes of this paragraph, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall -10-

11 be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (e) Non-Securities Act Claims. Indemnification or, if appropriate, contribution, similar to that specified in the preceding provisions of this Section 10 (with appropriate modifications) shall be given by Company and each Holder with respect to any required registration or other qualification of Registrable Securities pursuant to this Agreement under any federal or state law or regulation or governmental authority other than the Securities Act. (f) Payment. The Indemnifying Party shall promptly pay to the Indemnified Party in cash the amount of such indemnity or, if appropriate, contribution to which the Indemnified Party shall become entitled by reason of the provisions of this Section 10. 11. RULE 144 REPORTING With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Registrable Securities to the public without registration, during such time as a public market exists for the Common Stock, Company agrees to use its best efforts to: (a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times while Company is subject to the reporting requirements of the Securities Act or the Exchange Act; (b) File with the Commission in a timely manner all reports and other documents required of Company under the Securities Act and the Exchange Act (at any time while it is subject to such reporting requirements); and (c) Furnish to any Holder forthwith upon request a written statement by Company as to its compliance with the reporting requirements of Rule 144, and of the Securities Act and the Exchange Act (at any time while it is subject to such reporting requirements), a copy of the most recent annual or quarterly report of Company, and such other reports and documents of Company and other information in the possession of or reasonably obtainable by Company as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration. 12. ASSIGNMENT OF REGISTRATION RIGHTS The rights to register Registrable Securities pursuant to this Agreement may be assigned by a Holder to a transferee or assignee of such securities who shall, upon such transfer or assignment, be deemed a "Holder" under this Agreement; provided such transfer is effected in accordance with applicable securities laws and all restrictions on transfer applicable to such Registrable Securities and Company is, within a reasonable period of time after such transfer, furnished with written notice of -11-

12 the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; provided, further, that such assignment shall be effective only if immediately following such transfer, the further disposition of such securities by the transferee or assignee is restricted under the Securities Act and that such transferee or assignee is either (a) a shareholder of any Holder, (b) a member of the immediate family of such a shareholder or (c) a trust for the benefit of such a shareholder or such a shareholder's immediate family. 13. MISCELLANEOUS (a) All notices, requests, demands and other communications required or permitted to be given hereunder shall be in writing and shall be deemed to have been duly given if delivered personally, given by prepaid telex or telegram or by facsimile or other similar instantaneous electronic transmission device or mailed first class, postage prepaid, certified United States mail, return receipt requested, at the address indicated for such party on the signature pages hereof; provided that any party may change its address for notice by giving to the other party written notice of such change. Unless otherwise provided herein, any notice given under this Section 13(a) shall be effective when received at the address for notice for the party to which the notice is given. (b) Any term of this Agreement may be amended and the observance of any term may be waived (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of Company and the holders of a majority of the Registrable Securities. (c) If one or more provisions of this Agreement are held to be unenforceable under applicable law, such provision shall be excluded from this Agreement, and the balance of this Agreement shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms. (d) This Agreement shall for all purposes be governed by and construed in accordance with the laws of the State of Delaware, without regard to conflict of law principles. The parties hereto agree to submit to the jurisdiction of the federal and state courts of the State of Arizona with respect to the breach or interpretation of this Agreement or the enforcement of any and all rights, duties, liabilities, obligations, powers and other relations among the parties arising under this Agreement. The parties agree that non-exclusive venue of any action hereunder shall be proper in Phoenix, Maricopa County, Arizona. (e) This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. -12-

13 (f) This Agreement constitutes the full and entire understanding and agreement among the parties with respect to the subject matter hereof and supersedes all prior agreements with respect to the subject matter hereof. (g) Except as otherwise provided herein, the terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and permitted assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. (h) Each party acknowledges that it and its counsel have received, reviewed and been involved in the drafting of this Agreement and that normal rules of construction, to the effect that ambiguities are to be resolved against the drafting party, shall not apply.
