Upon the terms and subject to the conditions of this Agreement, the Seller agrees to sell to the Purchaser, and the Purchaser agrees to purchase from the Seller, for the consideration set forth below, the Shares at the Closing free and clear of any and all Liens. Section 2.2 Consideration. (a) Consideration for the Shares shall be an aggregate amount equal to Ten Million Two Hundred Fifty Thousand and No/100ths Dollars ($10,250,000.00) plus the amount of the Earnout Payment described in Section 2.2(b) below.

On the Maturity Date of the Promissory Note, the payment of such amounts due and payable under the Promissory Note shall be made in accordance with Section 10.4 below. (b) On the Earnout Payment Date, and subject to Section 2.2(c) below, Magellan shall pay (the "Earnout Payment") to the Holders' Representative (on behalf of the Holders) an amount in cash, or in Magellan's sole discretion, up to one-half of the Earnout Payment in shares (the "Earnout Shares") of Magellan Common Stock (or a combination thereof), equal to the product of (i) the Contribution Margin minus One Million and Nine Hundred Thousand Dollars and No/100ths ($1,900,000.00) (the "Margin Threshold") times (ii) three (3). If the difference between the Contribution Margin and the Margin Threshold calculated in accordance with Section 2.2(b)(i) above is zero or less than zero, the Earnout Payment shall equal zero. In addition, if the Empire Contract is not in force on the Earnout Payment Date (or Purchaser receives written or oral notice from Empire on or before the Earnout Payment Date that the Empire contract will be terminated or not renewed) the Earnout Payment shall equal zero. Under no circumstances shall the Earnout Payment exceed $10,000,000. The parties acknowledge that they may mutually elect to modify the method of calculating the Earnout Payment prior to the Closing Date. If Magellan shall choose to pay any portion of the Earnout Payment in Earnout Shares, the price per share (the "Stock Price") to be used in determining the number of shares to be issued shall be the average of the Closing Prices for the 10 Trading Days immediately preceding the Earnout Payment Date.

(c) Prior to the Earnout Payment Date, but in no event later than thirty (30) days prior to the Earnout Payment Date, Magellan shall deliver to Seller its good faith calculation of the Earnout Payment (the "Proposed Earnout Payment") to be paid to Seller on the Earnout Payment Date. Within twenty (20) days after receipt of the Proposed Earnout Payment, Seller shall notify Magellan of any objections Seller may have to the Proposed Earnout Payment. In the absence of any such objections, Seller shall be deemed to have approved the Proposed Earnout Payment for the purpose of calculating the Earnout Payment as described above. If Seller notifies Magellan of any such objections, Magellan and Seller shall attempt to resolve such objections in good faith for a period of 10 days from the date

of such notice of objection. If any objections of Seller cannot be resolved by Seller and Magellan within such 10-day period, (A) Magellan shall pay to Seller any such undisputed portion of the Earnout Payment on the Earnout Payment Date, and (B) any dispute regarding any remaining amounts shall immediately be referred to the Independent Accounting Firm mutually selected by the parties. The determination of such Independent Accounting Firm with respect to such dispute shall be conclusive and binding on the Seller, Magellan and the Purchaser. Magellan and the Seller shall each bear 50% of the fees and expenses of the Independent Accounting Firm. (d) In the event any Holder sells any Earnout Shares received in the Earnout Payment during the Resell Period (the "Selling Person") and the price received is less than the Stock Price, Magellan will pay to the Selling Person, in cash, for each share of Magellan common stock sold, the difference between the average price per share received by Selling Person and 95% of the Stock Price (if such average price per share is lower than 95% of the Stock Price). In the event any Holder sells any Earnout Shares during the Resell Period and the price received is greater than the Stock Price, the Selling Person will pay to Magellan, in cash, for each share of common stock sold, the difference between 105% of the Stock Price and the average price per share received by Selling Person (if such average price per share is higher than 105% of the Stock Price). The payments to be made pursuant to the two preceding sentences shall be determined and made within 10 days after the end of the Resell Period with respect to all shares sold during the Resell Period. Section 2.3 Earnout Rights. The Earnout Rights are not and shall not be deemed to be common stock, capital stock or equity of any of the Consolidated Allied Entities or any equivalent thereof, and the Holders of the Earnout Rights shall have none of the rights of shareholders of any of the Consolidated Allied Entities. The Earnout Rights shall be assignable only to the shareholders of the Seller, Affiliates of the shareholders of the Seller, to any entity which is established in connection with the liquidation and winding up of the Seller or to any person which is a beneficial owner of a shareholder of the Seller; provided however, that, notwithstanding the foregoing, the Earnout Rights may not be assigned to a customer or competitor of the Purchaser or a customer or competitor of any Affiliate of the Purchaser; and provided further that no assignment shall be effective unless (a) the assigning Holder provides written notice to the Purchaser specifying the amount or percentage of the Earnout assigned to each assignee; and (b) the assignee executes an agreement with the Purchaser agreeing (i) to be bound by all the provisions set forth in this Agreement regarding the Earnout Rights, including, without limitation, the indemnity obligations hereunder, and (ii) that all rights and obligations appurtenant to the Earnout Rights as set forth in this Agreement shall be exercisable by the Holders' Representative on behalf of all Holders of Earnout Rights, and acknowledging and affirming (y) the existence and effectiveness of the Related Collateral Documents (as defined in Section 9.2(g) below), each given by each of the Consolidated Allied Entities for the benefit of the creditor(s) under Magellan's bank credit agreement, and (z) of the obligations of Allied and its Subsidiaries, including the Company, to become signatories to the Related Collateral Documents. Notwithstanding the foregoing, the parties acknowledge and agree that the current shareholders of the Seller as of the date hereof shall not constitute customers or competitors of the Purchaser or any Affiliate of the Purchaser as such terms are used in Section 2.3(a) above. Purchaser also acknowledges that it is its intent to exercise good faith commercially reasonable efforts to promote, maintain and perform services under the Empire Contract; provided, however, that nothing set forth in this Agreement shall require the Purchaser to take any action or to refrain from taking any action with respect to the Empire Contract to the extent that Purchaser, in its reasonable good faith business judgment, believes that such action or inaction could have an adverse effect on the interests of the Purchaser, after giving due regard to the interests of Seller. From and after the Closing Date and until the Earnout Payment Date, the Purchaser shall deliver to the Seller quarterly reports on the financial performance of the Empire Contract, and shall promptly notify Seller of any material changes in the business conducted under said contract. The Seller agrees that all rights and obligations appurtenant to the Earnout Rights as set forth in this Agreement shall be exercisable by the Holders of the majority of the Earnout Rights on

15 days from the date of such notice of objection. If any objections of Magellan cannot be resolved by Seller and Magellan within such 15-day period, (A) Seller shall pay to Magellan any such undisputed portion of the payment due Magellan under Section 2.5(b)(iv) below, and (B) any dispute with regard to the Company Closing Balance Sheet or the calculation of the Tangible Net Equity shall immediately be referred to the Independent Accounting Firm mutually selected by the parties. The determination of such Independent Accounting Firm with respect to such dispute shall be conclusive and binding on the Seller, Magellan and the Purchaser. Magellan and the Seller shall each bear 50% of the fees and expenses of the Independent Accounting Firm. (iv) In the event that the Tangible Net Equity on the Company Closing Balance Sheet is less than zero (such amount less than zero is the "Company Deficit Amount"), the Seller shall pay to Magellan, in cash, the Company Deficit Amount within five business days of delivery of the Company Closing Balance Sheet or within five business days of receipt by the parties of the determination of the Independent Accounting Firm, as the case may be.

(a) Subject to the provisions of Section 7.3(b), and subject to the last sentence of this Section 7.3(a), if requested by the Purchaser, each of the Seller and the Purchaser shall make timely and irrevocable elections under Section 338(h)(10) of the Code and, if permissible, similar elections under any applicable state or local income Tax laws with respect to the Company and each of its

Subsidiaries. If so requested by the Purchaser, (i) the Seller will not, and will not permit the Company or any of its Subsidiaries to take, cause or permit to be taken any action that would disqualify this transaction as a deemed asset sale under Section 338(h)(10) of the Code, (ii) Purchaser shall not make a ratable allocation election under Section 1.1502-76(b)(2)(iii) of the Treasury Regulations (or similar provision of state law) without the Seller's consent, which consent shall not be unreasonably withheld, and (iii) each of the Seller and the Purchaser shall report the transaction consistent with such elections under Section 338(h)(10) or any similar state or local Tax provision (the "Elections") and shall take no position contrary thereto unless and to the extent required to do so pursuant to a Final Determination. Seller and the Purchaser agree that as a result of the Elections, any income or gain attributable to the deemed asset sales resulting from the Elections shall be included in the final Tax Returns of the Company for the Pre-Closing Tax Period to be filed with any Taxing Authority of a jurisdiction for which the Elections are applicable. Purchaser agrees to reimburse the Seller for 50 percent of the amount by which the federal income Tax payable by the Seller resulting solely from the filing of the Election exceeds the amount of federal income Tax that would have been payable by the Seller if such Election had not been made (such excess, the "Additional Tax"). Notwithstanding the foregoing, in the event the Additional Tax would be more than $4 million in the aggregate, the Seller shall not be required to make the Section 338(h)(10) election referred to in the first sentence above. (b) In states permitting an election separate from the federal Section 338(h)(10) Election, including, without limitation, the State of California, Seller shall have the right, in its sole discretion, to elect not to have any federal Section 338(h)(10) election apply for the purposes of computing the state income or franchise tax liability of Seller, Company or its Subsidiaries (a "State Negative Election"). If Seller elects to file a State Negative Election with respect to Company or any of its Subsidiaries, Purchaser will not take, cause or permit to be taken, and will not permit the Company or any of its Subsidiaries, on or after the Closing Date to take, cause or permit to be taken, any action which would disqualify the State Negative Election. If Seller does not file a State Negative Election, then any state Taxes arising out of the Elections shall be subject to the reimbursement provisions of the last sentence of Section 7.3(a). (c) As soon as the parties have reached final agreement with respect to the Company Closing Balance Sheet pursuant to Section 2.5, but in no event later than 150 days following the Closing Date, each of the Seller and Purchaser shall have negotiated in good faith to reach agreement as to the allocation of the aggregate consideration payable hereunder among the assets of the Company and its Subsidiaries in accordance with the requirements of Section 1060 of the Code. No value shall be assigned to the Earnout Payment until paid. If Purchaser notifies the Seller of Purchaser's desire to make the Elections pursuant to Section 7.3(a), then: (i) each of the Seller and Purchaser shall promptly execute any and all forms necessary to effectuate the Elections (including, without limitation, Internal Revenue Service Form 8023 (or any successor form) and any similar forms under applicable state and local income Tax laws (the "Section 338 Forms")), and (ii) each of the Seller and Purchaser shall cause the Section 338 Forms to be duly executed by an authorized Person and shall duly and timely file the Section 338 Forms in accordance with applicable Tax laws and the terms of this Agreement. (d) Each of the Seller and the Purchaser agrees that in making the Elections, it shall report the modified aggregate deemed sales price (as defined under applicable Treasury Regulations, the "MADSP") of the assets of the Company as calculated by not taking into account as an assumed liability any liability for Taxes to the extent that the Seller is required under this Article 7 to pay, reimburse or indemnify the Purchaser therefor. Each of the Seller and the Purchaser agrees to allocate such MADSP, consistent with the applicable Treasury Regulations, in the manner agreed upon by the Seller and Purchaser pursuant to Section 7.3(c). Each of the Seller and the Purchaser will reflect such allocation in all applicable Tax Returns filed by any of them, including but not limited to the Section 338 Forms. Neither the Seller nor the Purchaser (nor any of their Affiliates) shall take a position before any Taxing Authority or otherwise (including in any Tax Return) inconsistent with such allocation unless and to the extent required to do so pursuant to a Final Determination.

Section 7.4 Tax Returns. (a) Seller shall timely prepare all Tax Returns of the Company and its Subsidiaries for all Pre-Closing Tax Periods. Such Tax Returns shall be prepared in a manner consistent with past practice and, on such Tax Returns, no positions shall be taken, elections made, or methods adopted that are inconsistent with positions taken, elections made, or methods used in preparing similar Tax Returns in prior periods without the consent of the Purchaser which consent shall not be unreasonably withheld. (b) Seller shall file or cause to be filed when due all Tax Returns of the Company and its Subsidiaries for all Pre-Closing Tax Periods that are filed on a consolidated, combined, or unitary basis by the Seller (including all federal income Tax Returns, and including all Tax Returns of the Company and its Subsidiaries for the period ending on the Closing Date), and the Seller shall be responsible for the contents of such Tax Returns and for the payment of all Taxes shown to be due thereon; provided, however, that the Seller shall furnish the Purchaser and the Company with copies of such Tax Returns of the Company and its Subsidiaries, on a separate company basis, within 30 days following the filing date (15 days for any such state income or franchise Tax Returns filed with the states of California, Florida or Colorado). Seller shall prepare and send to the Company as promptly as practicable but at least five business days prior to the due date (including any permitted extensions) all other Tax Returns that are required to be filed by the Company and its Subsidiaries for all Pre-Closing Tax Periods, and the Seller or, after the Closing Date, the Purchaser shall file or cause to be filed when due such other Tax Returns. At least five (5) business days prior to the date on which the Taxes due with respect to such other Tax Returns are required to be paid, the Seller shall provide the Purchaser, without offset, with the funds, or (at the Seller's discretion, but only if electronic payment is not required) with checks payable to the appropriate governmental authorities, for the payment of all Taxes unpaid as of the Closing Date shown to be due on such other Tax Returns, and the Purchaser shall be responsible for the payment of all Taxes unpaid as of the Closing Date shown to be due on such other Tax Returns, provided that the Purchaser's obligation to pay such Taxes shall not limit the Purchaser's indemnification rights against the Seller pursuant to Section 7.7. If any such Tax Return shows an overpayment of Taxes due, Purchaser shall pay to Seller, without offset, the full refund of the amount no later than five business days after the earlier of the Purchaser's receipt of a refund on account of such overpayment and the application of such overpayment to offset a Tax liability of the Purchaser or an Affiliate of the Purchaser otherwise due. (c) Purchaser shall prepare and file all Tax Returns of the Company and each entity that is a Subsidiary of the Company immediately following the Closing for all Post-Closing Tax Periods. As promptly as practicable but at least five business days before the due date, the Purchaser shall furnish the Seller with copies of all Tax Returns of the Company and each entity that is a Subsidiary of the Company immediately following the Closing for any Post-Closing Tax Period that includes the Closing Date. At least five business days prior to the date on which the Taxes shown on such Tax Returns are required to be paid, the Seller shall provide the Purchaser, without offset, with the funds for the payment of all Taxes shown to be due on such Tax Returns that are attributable to the portion of such Tax periods ending on the Closing Date and the Purchaser shall be responsible for the payment of all Taxes shown to be due on such Tax Returns, provided that the Purchaser's obligation to pay such Taxes shall not limit the Purchaser's indemnification rights against the Seller pursuant to Section 7.7. If any such Tax Return shows an overpayment of Taxes due, Purchaser shall pay to the Seller, without offset, the amount of such refund that is attributable to the portion of such Tax period ending on the Closing Date no later than five business days after the earlier of the Purchaser's receipt of a refund on account of such overpayment and the application of such overpayment to offset a Tax liability of the Purchaser or an Affiliate of the Purchaser otherwise due. (d) In the event that the Seller liquidates or dissolves prior to filing the Tax Returns on which the receipt of the Earnout Payment is required to be reported, Seller shall designate the Holders' Representative (as appointed pursuant to Section 2.3) to file such Tax Returns (including any

amendment or modification to the Section 338 Forms to reflect the Earnout Payment) for the Seller and to pay all Taxes due with respect thereto. Section 7.5 Other Tax Matters. (a) All transfer, documentary, sales, use, stamp, and registration Taxes and fees (including any penalties and interest) incurred in connection with this Agreement, shall be paid one-half by the Seller and one-half by the Purchaser when due, and each party will, at its own expense, file all necessary Tax Returns and other documentation with respect to all such transfer, documentary, sales, use, stamp, registration and other Taxes and fees. (b) Certification to the effect that the Seller is not a "foreign person" as defined in Section 1445 of the Code shall be signed by the Seller and delivered to the Purchaser at or prior to the Closing. (c) Any and all existing Tax sharing agreements or arrangements between the Seller and the Company or any of its Subsidiaries shall be terminated as of the Closing Date. (d) The Seller shall engage (at its sole cost) a nationally or regionally recognized accounting firm to prepare the Federal Tax Returns of the Seller for the fiscal year ended November 30, 1999 and for its taxable year which includes the Closing Date. The Seller shall properly execute and file such Tax Returns when due and pay all Taxes due with respect thereto. Within 15 days following the filing by the Seller of its Federal Tax Returns for the taxable year ended November 30, 1999 and for the taxable year which includes the Closing Date, the Seller shall provide Purchaser with correct and complete copies of such Tax Returns in the form filed. In addition, Seller shall provide Purchaser on the Closing Date with correct and complete copies of any state Tax Returns of the Company or any of its Subsidiaries for the taxable year ending November 30, 1999 filed prior to the Closing Date. (e) The Seller agrees to provide Purchaser with copies of any amended Federal Tax Returns filed by Seller after the Closing Date for any taxable year ending before or including the Closing Date in the form filed within thirty (30) days after the filing thereof. Except as set forth on Schedule 7.5(e), the Seller agrees to provide the Purchaser with advance notice of any such filing if the Seller knows that such Federal Tax Returns will materially, adversely affect any state Tax Return of the Company or any of its Subsidiaries. Section 7.6 Cooperation on Tax Matters. (a) Purchaser and the Seller shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with any audit, litigation or other proceeding with respect to Taxes and with the preparation of any Tax Returns and requests for refunds. Such cooperation shall include the retention and (upon the other party's request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Company and the Seller agree (i) to retain all books and records with respect to Tax matters pertinent to the Company and its Subsidiaries relating to any Pre-Closing Tax Period, and to abide by all record retention agreements entered into with any Taxing Authority, and (ii) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, the Company or the Seller, as the case may be, shall not destroy or discard such books and records and shall allow the other party to take possession of such books and records. (b) Purchaser and the Seller further agree, upon request, to use their best efforts to obtain any certificate or other document from any governmental authority or customer of the Company or any of its Subsidiaries or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby). Section 7.7 Tax Indemnification.

(a) The covenants, agreements, representations and warranties of the parties hereto contained in this Article 7 or in any certificate or other writing delivered pursuant to this Article 7 or in connection herewith shall survive for such period as set forth in Section 10 herein, and any indemnification claims made under this Section 7.7 shall be made pursuant to Article 10 below. (b) Seller hereby agrees to indemnify the Purchaser Indemnified Parties (as defined in Section 10.2(a)) against and to hold them harmless from (i) any (x) Tax of the Company or any of its Subsidiaries and (y) liabilities, costs, expenses (including, without limitation reasonable expenses of investigation and attorneys' fees and expenses), losses, damages, assessments, settlements or judgments arising out of or incident to the imposition, assessment or assertion of any Tax of the Company or any of its Subsidiaries and any liability of the Company or any of its Subsidiaries as transferee, in each case related to the Tax Indemnification Period and in each case incurred or suffered by any Purchaser Indemnified Party or, effective upon the Closing, the Company or any of its Subsidiaries; and (ii) any and all Damages (as defined in Section 10.2(a)) incurred or suffered by the Purchaser Indemnified Parties arising out of any misrepresentation or breach of warranty, covenant or agreement made or to be performed by the Seller pursuant to this Article 7. The indemnification set forth in the preceding sentence shall not apply to or in respect of Taxes of the Company or any of its Subsidiaries to the extent that such Taxes were funded by a payment by the Seller to the Purchaser pursuant to Sections 7.4(b) or 7.4(c) or are the obligation of Purchaser pursuant to the penultimate sentence of Section 7.3(a). Purchaser hereby agrees to indemnify the Seller Indemnified Parties (as defined in Section 10.2(a)) against and to hold them harmless from any and all Damages incurred or suffered by the Seller Indemnified Parties arising out of any misrepresentation or breach of warranty, covenant or agreement made or to be performed by the Purchaser pursuant to this Article 7. (c) For purposes of Section 7.4(c) and this Section 7.7, in the case of any Taxes that are imposed on a periodic basis and are payable for a taxable period that includes (but does not end on) the Closing Date, the portion of such Tax related to the portion of such taxable period ending on the Closing Date shall (x) in the case of any Taxes other than Taxes based upon or related to income or gross receipts, be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction the numerator of which is the number of days in the taxable period ending on the Closing Date and the denominator of which is the number of days in the entire taxable period, and (y) in the case of any Tax based upon or related to income or gross receipts, be deemed equal to the amount which would be payable if the relevant taxable period ended on the Closing Date. Any credits relating to a taxable period that begins before and ends after the Closing Date shall be taken into account as though the relevant taxable period ended on the Closing Date. All determinations necessary to give effect to the foregoing allocations shall be made in a manner consistent with prior practice of the Company and its Subsidiaries. (d) Purchaser agrees to give prompt notice to the Seller of the assertion of any claim, or the commencement of any suit, action or proceeding in respect of which indemnity may be sought hereunder, which the Purchaser deems to be within the ambit of this Section 7.7 (specifying with particularity the basis therefor) and will give the Seller such information with respect thereto as the Seller may request. Seller may, at its own expense, (i) participate in and, (ii) upon notice to the Purchaser, assume the defense of any such suit, action or proceeding; provided that, (y) the Seller shall thereafter consult with the Purchaser upon the Purchaser's reasonable request for such consultation from time to time with respect to such suit, action or proceeding, and (z) the Seller shall not, without the Purchaser's consent, which consent shall not be unreasonably withheld, agree to any settlement with respect to any Tax if such settlement could materially adversely affect the past, present or future Tax liability of the Purchaser, any of its Affiliates or, upon the Closing, the Company or any of its Subsidiaries. If the Seller assumes such defense, the Purchaser shall have the right (but not the duty) to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Seller. Whether or not the Seller chooses to defend or prosecute any claim, all of the parties hereto shall cooperate in the defense or prosecution thereof.

(e) Seller agrees to give prompt notice to the Purchaser of the assertion of any claim, or the commencement of any suit, action or proceeding in respect of which indemnity may be sought hereunder which the Seller deems to be within the ambit of this Section 7.7 (specifying with particularity the basis therefor) and will give the Purchaser such information with respect thereto as the Purchaser may request.

Whether or not the Purchaser chooses to defend or prosecute any claim, all of the parties hereto shall cooperate in the defense or prosecution thereof. (f) Seller shall not be liable under this Section 7.7 with respect to any Tax resulting from a claim or demand the defense of which the Seller was not offered the opportunity to assume, as provided under Section 7.7(d) hereof, to the extent the Seller's liability under Section 7.7(b) is adversely affected as a result thereof.
