     (a) At the Effective Time, each share of JetStar common stock, par value $0.0001 per share (each a “JetStar Common Share” and collectively the “JetStar Common Shares”), and each share of JetStar Series A Convertible Preferred Stock, par value $0.0001 per share (each, a “JetStar Preferred Share”, collectively, the “JetStar Preferred Shares” and, together with the JetStar Common Shares, the “JetStar Shares”), issued and outstanding immediately prior to the Effective Time shall, except as provided inSection 2.6 (with respect to Dissenting JetStar Shares), by virtue of the Merger and without any action on the part of Basic, Merger Sub, JetStar or any holder thereof, be converted into (i) the right to receive the cash and Basic Common Shares specified inSection 2.2(c)(i) andSection 2.2(c)(ii) and (ii) certain other rights and benefits provided to former holders of JetStar Shares under this Agreement (including under Article 8).

(A) at the Effective Time (x) as consideration (together with any Basic Common Shares specified inSection 2.2(c)(i)(B)) for one-half of each such JetStar Common Share, a number of Basic Common Shares equal to (1) the Preliminary Total Stock Portion divided by the Basic Share Price, divided by (2) the Partially-Diluted JetStar Shares, and (y) as consideration (together with any cash specified inSection 2.2(c)(i)(B)) for the other one-half of each such JetStar Common Share, cash in an amount equal to (1) the Reallocated Total Cash Portion minus the Escrow Deposit, divided by (2) the Partially-Diluted JetStar Shares (which cash amount, in the case of an Exercising Optionholder, may be offset and used to repay any amounts outstanding and unpaid under the Exercising Optionholder’s Option Loan); and

(B) after the Effective Time, any amounts (x) distributable to a former holder of JetStar Common Shares as provided inSection 2.4(b)(i),Section 2.4(b)(ii),Section 2.4(b)(iii) and the Escrow Agreement and (y) payable to a former holder of JetStar Common Shares by Basic after the Effective Time as provided inSection 2.5(c)(iii).

-5-

Time into the right to receive (in addition to the other rights under this Agreement (including under Article 8)):

(A) at the Effective Time, (x) as consideration (together with any Basic Common Shares specified inSection 2.2(c)(ii)(B)) for one-half of each such JetStar Preferred Share, a number of Basic Common Shares equal to (1) the Preliminary Total Stock Portion divided by the Basic Share Price divided by (2) the Partially-Diluted JetStar Shares, multiplied by (3) the number of JetStar Common Shares into which such JetStar Preferred Share could have been converted as of the Effective Time, and (y) as consideration (together with any cash specified inSection 2.2(c)(ii)(B)) for the other one-half of each such JetStar Preferred Share, cash in an amount equal to (1) the Reallocated Total Cash Portion minus the Escrow Deposit, divided by (2) the Partially-Diluted JetStar Shares, multiplied by (3) the number of JetStar Common Shares into which such JetStar Preferred Share could have been converted as of the Effective Time; and

(B) after the Effective Time, any amounts (x) distributable to a former holder of JetStar Preferred Shares as provided inSection 2.4(b)(i),Section 2.4(b)(ii),Section 2.4(b)(iii) and the Escrow Agreement and (y) payable to a former holder of JetStar Preferred Shares by Basic after the Effective Time as provided inSection 2.5(c)(iii).

     (d) Rights of Holders. Upon the Effective Time, the holders of certificates that represented JetStar Shares (a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive, upon surrender of such Certificate, in accordance with the terms of this Agreement, the cash and Basic Common Shares to which such holder is entitled pursuant toSection 2.2(c) and the other rights under this Agreement (including under Article 8). Until surrendered as contemplated bySection 2.3(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive such cash and Basic Common Shares and to have such other rights upon such surrender and such holder shall not be entitled to vote or to any other rights of a stockholder of Basic until after such surrender.

     (e) Cancellation of Excluded JetStar Shares.

          (i) Each JetStar Common Share that is owned by JetStar or any Subsidiary of JetStar (the “Excluded JetStar Common Shares”) issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, no longer be outstanding, shall be canceled and retired without payment of any consideration therefor and shall cease to exist.

          (ii) Each JetStar Preferred Share that is owned by JetStar or any Subsidiary of JetStar (the “Excluded JetStar Preferred Shares” and, together with the Excluded JetStar Common Shares, the “Excluded JetStar Shares”) issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, no longer be outstanding, shall be canceled and retired without payment of any consideration therefore and shall cease to exist.

-6-

     (f) Merger Sub. At the Effective Time, the limited liability company interests of Merger Sub issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and shall be the issued and outstanding limited liability company interests of the Surviving Entity.

     SECTION 2.3EXCHANGE AGENT; EXCHANGE OF CERTIFICATES; PAYMENTS TO REMAINING OPTION HOLDERS.

     (a) Exchange Agent. At or prior to the Closing, Basic shall deposit, in trust for the benefit of the former holders of JetStar Shares, the cash and Basic Common Shares required to make the payments required to be made underSection 2.2(c)(i)(A) andSection 2.2(c)(ii)(A) with American Stock Transfer and Trust Company (or another bank or trust company that is organized and doing business under the laws of the United States or any state thereof that shall be appointed to act as exchange agent hereunder and approved in advance by JetStar in writing) (the “Exchange Agent”) pursuant to an agreement in form and substance reasonably satisfactory to Basic and JetStar. Such cash and Basic Common Shares will not be used by the Exchange Agent for any other purpose. For purposes of determining the amount of cash and the number of Basic Common Shares to be deposited with the Exchange Agent, Basic shall assume that the only Dissenting JetStar Shares will be those held by holders of JetStar Shares who have perfected appraisal rights prior to the time the deposit is made.

     (b) Exchange Procedures.

          (i) Promptly after the Effective Time, but in no event later than five Business Days thereafter, Basic shall cause the Exchange Agent to mail to each record holder of JetStar Shares as of the Effective Time (other than holders of Excluded JetStar Shares or Dissenting JetStar Shares) (i) a letter of transmittal specifying that delivery of the Certificates shall be effected, and that risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent, such letter of transmittal to be in such form and to have such other provisions as Basic and JetStar reasonably agree (including representations from the former holders of the JetStar Shares acknowledging the restrictions applicable to the Basic Common Shares issuable in connection with the Merger), and (ii) instructions for exchanging the Certificates and receiving the cash and Basic Common Shares which such holder shall be entitled to receive pursuant toSection 2.2(c)(i)(A) orSection 2.2(c)(ii)(A), as applicable and (iii) a signature page for the Registration Rights Agreement. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor (x) a certificate representing that number of Basic Common Shares that such holder is entitled to receive pursuant toSection 2.2(c)(i)(A) orSection 2.2(c)(ii)(A), as applicable and (y) a check in the aggregate amount of cash that such holder is entitled to receive pursuant toSection 2.2(c)(i)(A) orSection 2.2(c)(ii)(A), as applicable. Basic and the Company shall also use their commercially reasonable efforts to establish procedures with the Exchange Agent so that any holder of JetStar Shares who delivers such materials, duly executed, on or prior to the Closing Date, may receive payment no later than the Business Day immediately succeeding the day on which the Effective Time occurs. The Certificate so surrendered shall forthwith be canceled.

-7-

          (ii) In the event of a transfer of ownership of JetStar Shares (other than Excluded JetStar Shares or Dissenting JetStar Shares) that occurred prior to the Effective Time, but that is not registered in the transfer records of JetStar, the cash and Basic Common Shares that the transferee would have been entitled to receive underSection 2.2(c)(i)(A) orSection 2.2(c)(ii)(A), as applicable, if such transferee had been the record holder of such JetStar Shares as of the Effective Time, may be issued and/or paid to such a transferee if the Certificate formerly representing such JetStar Shares is presented to the Exchange Agent, accompanied by all documents reasonably required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid.

          (iii) If any certificate for Basic Common Shares is to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of such exchange that the Person requesting such exchange shall pay any transfer or other Taxes required by reason of the issuance of certificates for Basic Common Shares in a name other than that of the registered holder of the surrendered Certificate, or shall establish to the reasonable satisfaction of Basic and the Exchange Agent that such Tax has been paid or is not applicable.

     (c) Distributions with Respect to Unexchanged Shares. Whenever a dividend or other distribution is declared by Basic in respect of Basic Common Shares, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all Basic Common Shares payable to the former holders of JetStar Shares (other than Dissenting JetStar Shares) pursuant to this Agreement. No dividends or other distributions so declared in respect of such Basic Common Shares shall be paid to any holder of any unsurrendered Certificate until such Certificate is surrendered for exchange in accordance withSection 2.3(b). Subject to the effect of applicable laws, following surrender of any such Certificate, Basic shall issue or pay to the holder of the certificates representing whole Basic Common Shares issued in exchange for such Certificate (i) at the time of such surrender, the dividends or other distributions with a record date that is at or after the Effective Time and a payment date on or prior to the date of surrender of such Certificate and not previously paid to such holder and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such Basic Common Shares with a record date at or after the Effective Time but with a payment date subsequent to surrender. For purposes of dividends or other distributions in respect of Basic Common Shares, all Basic Common Shares issued pursuant to the Merger shall be deemed to have been issued and outstanding as of the Effective Time.

     (d) Transfers after the Effective Time. After the Effective Time, there shall be no transfers on the stock transfer books of JetStar of JetStar Shares that were outstanding immediately prior to the Effective Time.

     (e) Fractional Shares. Notwithstanding any other provision of this Agreement, no certificates or scrip for fractional Basic Common Shares shall be issued in the Merger and no Basic Common Shares dividend, stock split, subdivision or interest shall relate to any fractional security, and such fractional interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Basic. In lieu of any such fractional share (after aggregating all fractional Basic Common Shares to be received by such holder), each holder of JetStar Shares (other than Dissenting JetStar Shares) who would otherwise have been entitled to receive a

-8-

fraction of a Basic Common Share upon surrender of a Certificate for exchange shall be entitled to receive a cash payment from Basic equal to such fraction multiplied by the Basic Share Price. No interest shall be payable with respect to any amounts to be paid under thisSection 2.3(e).

     SECTION 2.5POST-CLOSING ADJUSTMENTS.

     (a) Estimated Closing Statement. At least five (5) Business Days prior to the Closing Date, JetStar will deliver to Basic a statement (the “Estimated Closing Statement”) setting forth, in reasonable detail, JetStar’s good faith estimate of Net Working Capital (as defined below) and Net Debt (as defined below), in each case as of the last day of the month immediately preceding the month in which the Closing occurs or such more recent practicable date prior to the Closing. Such estimates are referred to in this Agreement as the “Estimated Net Working Capital” and the “Estimated Net Debt”, respectively. For illustrative purposes only, attached hereto asSchedule Iis a format to be used in determining the Estimated Net Working Capital and Estimated Net Debt. JetStar will make available to Basic all work papers and other books and records utilized in calculating Estimated Net Working Capital and Estimated Net Debt. The amount, if any, by which Estimated Net Working Capital is less than $5,000,000 (the “Target Net Working Capital”) is the “Estimated Net Working Capital Deficit”, and the amount, if any, by which the Estimated Net Working Capital exceeds the Target Net Working Capital is the “Estimated Net Working Capital Excess.” The amount, if any, by which the Estimated Net Debt exceeds $38,000,000 (the “Target Net Debt”) is the “Estimated Net Debt Deficit”, and the amount, if any, by which the Estimated Net Debt is less than the Target Net Debt is the “Estimated Net Debt Excess.” At the Effective Time the Base Price shall be adjusted by the Estimated Closing Adjustment (as defined inSection 2.5(d)).

     (b) Post-Closing Statement. As promptly as practicable but in any event within 90 days after the Closing, Basic will prepare a statement (the “Post-Closing Statement”) setting forth, in reasonable detail, Basic’s calculation of the actual Net Working Capital as of the Closing and the actual Net Debt as of the Closing. The methodology used to calculate Net Working Capital and Net Debt on the Post-Closing Statement shall be the same as those on the Estimated Closing Statement. Basic shall deliver the Post-Closing Statement to the JetStar Stockholders’ Representative, and will also make available to the JetStar Stockholders’ Representative copies of all work papers and other books and records utilized in the preparation of the Post-Closing Statement. The JetStar Stockholders’ Representative will have 20 days after receipt of the Post-Closing Statement to review such calculations and to reasonably object to same. Basic and the JetStar Stockholders’ Representative will resolve any dispute regarding such calculations as provided inSection 9.7. The Post-Closing Statement, either as prepared by

-11-

Basic or as determined pursuant to the dispute resolution provisions ofSection 9.7, is the “Final Closing Statement.”

     (c) Final Adjustments. The consideration paid by Basic in connection with this Agreement will be adjusted based on the Final Closing Statement as follows:

          (i) Net Debt Adjustment. If the Net Debt shown on the Final Closing Statement (the “Final Net Debt”) is greater than the Estimated Net Debt the consideration payable by Basic in connection with this Agreement shall be reduced by an amount equal to the Final Net Debt minus the Estimated Net Debt. If the Final Net Debt is less than the Estimated Net Debt the consideration payable by Basic in connection with this Agreement shall be increased by an amount equal to the Estimated Net Debt minus the Final Net Debt.

          (ii) Working Capital Adjustment. If the Net Working Capital shown on the Final Closing Statement (the “Final Net Working Capital”) is greater than the Estimated Net Working Capital, the consideration payable by Basic in connection with this Agreement shall be increased by an amount equal to the Final Net Working Capital minus the Estimated Net Working Capital. If the Final Net Working Capital is less than the Estimated Net Working Capital, the consideration payable by Basic under this Agreement shall be reduced by an amount equal to the Estimated Net Working Capital minus the Final Net Working Capital.

          (iii) Netting. The increases or decreases in the consideration payable by Basic determined under clauses (i) and (ii) above shall be netted against each other. Any net reduction in the consideration payable by Basic in connection with this Agreement after application ofSection 2.5(c)(i) andSection 2.5(c)(ii) shall be deducted from the Escrow Account and paid to Basic by the Escrow Agent at the time of delivery of the Final Closing Statement. Any net increase in the consideration payable by Basic in connection with this Agreement after application ofSection 2.5(c)(i) andSection 2.5(c)(ii) will be paid to the former holders of JetStar Shares (excluding Dissenting JetStar Shares), pro rata according to the number of Partially-Diluted JetStar Shares represented thereby. Any such payments will be made to the former holders of JetStar Shares (other than Dissenting JetStar Shares) in cash and Basic Common Shares. The cash and Basic Common Shares payable pursuant to the immediately preceding sentence shall be allocated among the recipients thereof in the same manner as the right to receive payments of cash and Basic Common Shares was allocated among the holders of JetStar Shares (other than Dissenting JetStar Shares) as of the Effective Time. Any payments made to Basic out of the Escrow Deposit shall be treated as a reduction in the consideration paid by Basic in connection with the Merger. Any payments made by Basic pursuant to thisSection 2.5(c)(iii) shall be treated as an increase in the consideration paid by Basic in connection with the Merger.

     (d) Certain Defined Terms. For purposes of this Agreement:

          (i) “Estimated Closing Adjustment” equals the Estimated Net Debt Excess, if any, plus the Estimated Net Working Capital Excess, if any, minus the Estimated Net Debt Deficit, if any, minus the Estimated Net Working Capital Deficit, if any.

          (ii) “GAAP” means generally accepted accounting principles in the United States, consistently applied. In preparing the Post-Closing Statement, Basic shall not change the

Dissenting JetStar Shares shall not be converted into a right to receive the cash or Basic Common Shares under this Agreement, unless such holder fails to perfect, withdraws or otherwise loses his right to appraisal. If, after the Effective Time, such holder fails to perfect, withdraws or loses his right to appraisal, such shares shall be treated as if they had been converted at the Effective Time into the right to receive the cash and Basic Common Shares such holder would have received in connection with the Merger and the other transactions contemplated by this Agreement, and Basic shall promptly provide to the Exchange Agent the cash and Basic Common Shares to which such former holder of Dissenting JetStar Shares shall be entitled to receive pursuant to the terms of this Agreement.

Except as required by applicable law or with the prior written consent of Basic, JetStar shall not make any payment with respect to, or settle or offer to

Basic and Merger Sub agree that payments to any holder of Dissenting JetStar Shares as a result of such holder’s exercise of appraisal rights pursuant to Section 262 of the DGCL shall be made from the assets of the Surviving Entity and not from the assets of Basic or assets provided by Basic.

Prior to the Closing, Basic may notify JetStar in writing of any Environmental Claims or other non-compliance with Environmental Laws by JetStar or any Subsidiary of JetStar, or any Person whose liability for an Environmental Claim JetStar or any Subsidiary of JetStar has retained, assumed or indemnified either contractually or by operation of law (including any such matters set forth on Schedule 3.13(b)(iv) of the JetStar Disclosure Letter) (an “Environmental Defect”).

-34-

     (a) JetStar agrees that, from the date hereof until the earlier of the Termination Date or the Effective Time, it (i) will not (and will not permit its officers, directors, employees, agents or representatives, including any investment banker, attorney or accountant retained by it, to) solicit, initiate or encourage (including by way of furnishing non-public information) any inquiry, proposal or offer (including any proposal or offer to its stockholders) with respect to a third party tender offer, merger, consolidation, business combination or similar transaction involving any assets or class of capital stock of JetStar, or any acquisition of the capital stock of JetStar or a business or assets (other than sales of assets in the ordinary course of business) of JetStar in a single transaction or a series of related transactions, or any combination of the foregoing (any such proposal, offer or transaction being hereinafter referred to as a “JetStar Acquisition Proposal”) or participate or engage in any discussions or negotiations concerning a JetStar Acquisition Proposal; and (ii) will immediately cease and cause to be terminated any existing discussions or negotiations with any third parties conducted heretofore with respect to any JetStar Acquisition Proposal; provided that, subject toSection 7.3(b), nothing contained in this Agreement shall prevent JetStar or its Board of Directors from (A) making any disclosure to the holders of JetStar Shares if in the good faith judgment of JetStar’s Board of Directors failure to make such disclosure would be inconsistent with its fiduciary duties under applicable law or (B) providing information (pursuant to a confidentiality agreement in reasonably customary form and which does not contain terms that prevent JetStar from complying with its obligations under thisSection 5.2(a)) to or engaging in any negotiations or discussions with any person or group who has made an unsolicited bona fide JetStar Acquisition Proposal with respect to all of the outstanding shares of capital stock of JetStar or all or substantially all of the assets of JetStar if, with respect to the actions set forth in clause (B), (x) in the good faith judgment of JetStar’s Board of Directors, taking into account, among other things, the likelihood of consummation and after consultation with its financial advisors, such JetStar Acquisition Proposal is reasonably likely to result in a transaction more favorable to the holders of JetStar Shares from a financial point of view than the Merger (a “JetStar Superior Proposal”) and (y) the Board of Directors of JetStar, after consultation with its outside legal counsel, determines in good faith that the failure to do so would be inconsistent with its fiduciary obligations under applicable law.

     (b) JetStar agrees that it will notify Basic promptly (and in any event within 24 hours) if any proposal or offer relating to or constituting a JetStar Acquisition Proposal is received by, any information is requested from, or any discussions or negotiations are sought to be initiated or continued with, JetStar or any of its officers, directors, employees, agents or representatives.

     (c) Nothing in thisSection 5.2 shall permit JetStar to enter into any agreement with respect to a JetStar Acquisition Proposal during the term of this Agreement, it being agreed that, during the term of this Agreement, JetStar shall not enter into any agreement with any person

     SECTION 8.5PROCEDURE FOR CLAIMS. Subject to the limitations set forth in this Article 8, all claims for Indemnified Buyer Losses or Indemnified JetStar Losses under this Article 8 shall be asserted and resolved by either a Basic Indemnified Person or a JetStar Indemnified Person (each, an “Indemnified Person”) as follows:

     (a) An Indemnified Person shall promptly give Basic or the JetStar Stockholders’ Representative, as applicable (each an “Indemnifying Person,” as applicable) notice of any matter that such Indemnified Person has determined has given or could give rise to a claim for indemnification (a “Claim Notice”) under this Article 8, stating the amount of the Indemnified Buyer Loss or Indemnified JetStar Loss, if known, and method of computation thereof, all with reasonable particularity, and stating with particularity the nature of such matter. Failure to provide such Claim Notice shall not affect the indemnification rights of such Indemnified Person hereunder except to the extent such failure shall have resulted in Indemnified Buyer Losses or Indemnified JetStar Losses that could have been actually avoided had such Claim Notice been provided within such required time period or to the extent such Claim Notice shall not have been sent within the time limitations set forth in this Article 8. The Indemnifying Person shall, within thirty (30) days after its receipt of a Claim Notice, notify the Indemnified Person in writing as to whether the Indemnifying Person admits or disputes the claim described in the Claim Notice. If the Indemnifying Person gives written notice that it admits the indemnification claim described in such Claim Notice, then the Indemnified Person shall be entitled to indemnification pursuant to the provisions of this Article 8, and subject to the limitations hereof, with respect to the estimated amount of Indemnified Buyer Losses or Indemnified JetStar Losses stated in the Claim Notice. If the Indemnifying Person notifies the Indemnified Person in writing that it disputes such claim for indemnification, or that it admits the entitlement of the Indemnified Person to indemnification under this Article 8 with respect thereto but disputes the amount of the Indemnified Buyer Losses or Indemnified JetStar Losses in connection therewith, or if the Indemnifying Person fails to notify the Indemnified Person within such thirty (30) day period that it either admits or disputes such claim for indemnification, then in either of such cases the indemnification claim described in the Claim Notice shall be a disputed indemnification claim that must be resolved by settlement between the Indemnified Person and the Indemnifying Person, or by proceedings commenced in an appropriate court of competent jurisdiction by either the Indemnifying Person or the Indemnified Person, or by any other mutually agreeable method.

     (b) If a claim is asserted against an Indemnified Person by a person other than a party to this Agreement and is based on factual allegations which, if true, would entitle the Indemnified Person to indemnification hereunder (any such claim, a “Third Party Claim”), the Indemnified Person against whom the Third Party Claim is asserted shall give written notice (a “Third Party Claim Notice”) to the Indemnifying Person of the assertion of such Third Party Claim, describing in such notice in reasonable detail to the extent then known the nature of the Third Party Claim and the factual basis and circumstances surrounding same and estimating the amount of Indemnified Buyer Losses or Indemnified JetStar Losses attributable to such Third Party Claim to the extent feasible (which estimate shall not be conclusive of or binding as to the final amount of such indemnification claim). A copy of all papers served on or received by the Indemnified Person with respect to such Third Party Claim, if any, shall be attached to the Third Party Claim Notice. The failure of an Indemnified Person to properly deliver a Third Party Claim Notice to the Indemnifying Person shall not defeat or prejudice the indemnification rights under this Article 8 of such Indemnified Person with respect to the related Third Party Claim

-49-

unless and except to the extent that the resulting delay is materially prejudicial to the defense of the Third Party Claim or the amount of Indemnified Buyer Losses or Indemnified JetStar Losses associated therewith. Within fifteen (15) days after receipt of any Third Party Claim Notice with respect to a Third Party Claim (the “Election Period”), the Indemnifying Person shall notify the Indemnified Person who provided the Third Party Claim Notice in writing that the Indemnifying Person either (i) disputes the right of the Indemnified Person to indemnification under this Article 8 with respect to that Third Party Claim, or (ii) admits the right of the Indemnified Person to indemnification under this Article 8 with respect to Indemnified buyer Losses or Indemnified JetStar Losses arising in connection with that Third Party Claim. The failure of the Indemnifying person to respond to the Indemnified Person within such fifteen (15) day period after receipt of a Third Party Claim Notice by the shall be deemed to constitute a response by the Indemnifying Person that it denies the right of such Indemnified Person to indemnification under this Article 8 with respect to that Third Party Claim.

     (c) If the Indemnifying Person admits that an Indemnified Person is entitled to indemnification under this Article 8 with respect to a Third Party Claim, then in such event (i) the Indemnifying Person shall defend the Third Party Claim with counsel approved by the Indemnified Person (which approval shall not be unreasonably withheld, delayed or conditioned), and if the Indemnifying Person is the JetStar Stockholders’ Representative, the reasonable costs of such defense incurred by the Indemnifying Person shall be paid from the Escrow Deposit, and (ii) the Indemnifying Person shall not enter into any settlement of the Third Party Claim unless such settlement is approved in writing by the Indemnified Person (which approval may not be unreasonably withheld, delayed or conditioned). In the event the Indemnifying Person assumes the defense against any such Third Party Claim as provided above, the Indemnified Party shall have the right to participate in the defense of such asserted liability, shall cooperate with the Indemnifying Person in such defense and will attempt to make available on a reasonable basis to the Indemnifying Person all witnesses, pertinent records, materials and information in its possession or under its control relating thereto as is reasonably required by the Indemnifying Person. The Indemnified Party shall have the right to employ separate counsel in any such action and participate in the defense thereof; provided that the fees and expenses of such separate counsel shall be at the expense of the Indemnified Party unless the employment of such counsel shall have been specifically authorized in writing by the Indemnifying Person or the Indemnified Party shall have been advised by such counsel that there is one or more legal defenses available to it that are different from or additional to those available to the Indemnifying Person. In any such case, the Indemnified Buyer Losses or Indemnified JetStar Losses shall not, in connection with any one action or separate but substantially similar or related action in the same jurisdiction arising out of the same general allegations or circumstances, include the fees and expenses of more than one separate firm of attorneys (in addition to local counsel) for the Indemnified Party. In the event the Indemnifying Party does not elect to conduct the defense against any such Third Party Claim, the Indemnified Buyer Losses or Indemnified JetStar Losses shall include all reasonable costs and expenses of such defense as incurred by the Indemnified Party and the Indemnifying Party shall cooperate with the Indemnified Party (and be entitled to participate) in such defense and attempt to make available to it on a reasonable basis all such witnesses, records, materials and information in its possession or under its control relating thereto as is reasonably required by the Indemnified Party. If the Indemnifying Person disputes the right of the Indemnified Person to indemnification under this Article 8 with respect to the Third Party Claim described in a Third Party Claim Notice, then in such event (i) the

-50-

Indemnified Person may defend the Third Party Claim with counsel of its choice and may enter into a settlement thereof without seeking or obtaining approval of the Indemnifying Person as to counsel employed or for the making of such settlement, and (ii) the amount of Indemnified Buyer Losses or Indemnified JetStar Losses incurred by the Indemnified Person in connection with such Third Party Claim, and the Indemnified Person’s right to indemnification under this Article 8 with respect thereto, shall be a disputed indemnification claim to be resolved by settlement between the Indemnifying Person and the Indemnified Person, or by appropriate proceedings in any court of competent jurisdiction.

     (d) Payment of all amounts determined pursuant to this Section 8.5 to be owed to a Basic Indemnified Person shall be made by only by the Escrow Agent, only to the extent contemplated bySection 2.4(a), in accordance with the terms ofSection 2.4(b)(iii) and the Escrow Agreement, and within ten (10) days after (i) the making of a binding settlement, or (ii) the expiration of all appeal rights from a final adjudication of a court of competent jurisdiction with respect thereto, or (iii) the final and non-appealable determination of such liability and amount by any other resolution method undertaken pursuant to the mutual written agreement of the Basic Indemnified Person and the JetStar Stockholders’ Representative. Payment of all amounts determined pursuant to this Section to be owed to a JetStar Indemnified Person shall be made by Basic, within ten (10) days after (i) the making of a binding settlement, or (ii) the expiration of all appeal rights from a final adjudication of a court of competent jurisdiction with respect thereto, or (iii) the final and non-appealable determination of such liability and amount by any other resolution method undertaken pursuant to the mutual written agreement of Basic and the JetStar Indemnified Person. Any such payment shall be paid to the JetStar Stockholders’ Representative for the account of such JetStar Indemnified Person, and shall be paid to the former holders of JetStar Shares (other than Dissenting JetStar Shares), pro rata according to the number of Partially-Diluted JetStar Shares represented thereby; provided that any such payments will be made to the former holders of JetStar Shares (other than Dissenting JetStar Shares) in cash and Basic Common Shares. The cash and Basic Common Shares payable pursuant to the immediately preceding sentence shall be allocated among the recipients thereof in the same manner as the right to receive payments of cash and Basic Common Shares was allocated among the holders of JetStar Shares (other than Dissenting JetStar Shares) as of the Effective Time. Any payments made to Basic out of the Escrow Deposit shall be treated as a reduction in the consideration paid by Basic in connection with the Merger. Any payments made by Basic pursuant to thisSection 8.5(d) shall be treated as an increase in the consideration paid by Basic in connection with the Merger.

     SECTION 8.6EXCLUSIVE POST-CLOSING REMEDY. After the Closing, and except for any non-monetary, equitable relief to which any Indemnified Person may be entitled, the rights and remedies set forth in this Article 8 shall constitute the sole and exclusive rights and remedies of the Indemnified Persons under or with respect to the subject matter of this Agreement.

     SECTION 8.7LIABILITY LIMITATIONS. In no event shall any Indemnified Person be, under or in respect of this Agreement, entitled to recover indirect, incidental, consequential, punitive or exemplary damages. Additionally, Basic, Merger Sub and JetStar hereby waive as to each former officer and director of JetStar, from and after the Closing, any and all claims and any causes of action for monetary damages under or with respect to the

-51-

subject matter of this Agreement (other than any claims or causes of action arising out of the express provisions of this Article 8) or, to the extent liabilities with respect thereto would be subject to indemnification as provided in the respective certificate of incorporation or bylaws or other organization documents of JetStar or its Subsidiaries or in any applicable JetStar Material Contract, any breach or alleged breach of fiduciary obligation by such officer or director to JetStar that Basic, Merger Sub or JetStar might otherwise be entitled to assert against any such former officer or director, including under any law.

If the JetStar Stockholders’ Representative timely disputes the determination of the actual Net Working Capital or the actual Net Debt as shown on the Post-Closing Statement, Basic and the JetStar Stockholders’ Representative will use their commercially reasonable efforts to negotiate an agreement on such amounts. If the parties cannot agree within thirty (30) Business Days after the date Basic receives notice of the JetStar

-54-

Stockholders’ Representative’s objection, then the issues in dispute will be submitted to Grant Thornton LLP, certified public accountants (the “Accountants”) located within the State of Texas, for resolution. Each party will promptly furnish to the Accountants such workpapers and other documents and information relating to the disputed issues as the Accountants may request and which are available to that party or its Subsidiaries (or its independent public accountants), and will be afforded the opportunity to present to the Accountants any material relating to the determination and to discuss the determination with the Accountants. Basic and the JetStar Stockholders’ Representative will use their commercially reasonable efforts to cause the Accountants to deliver a final resolution of any disputed amounts within 30 days of the date such issues were submitted to the Accountants. The Accountants shall resolve such disputed amounts based solely on the submissions of Basic and the JetStar Stockholders’ Representative, and each item or amount in dispute must be resolved so that it falls within the ranges presented to the Accountants. The determination by the Accountants of the actual Net Working Capital and/or the actual Net Debt, as set forth in a notice delivered to both parties by the Accountants will be binding and conclusive (and such amounts will be the Final Net Working Capital and the Final Net Debt for purposes ofSection 2.5(b)). The party whose calculation of Net Working Capital and Net Debt (on an aggregate basis) was further from the sum of the Final Net Working Capital and Final Net Debt (as determined by the Accountants) shall pay the fees and expenses of the Accountants.

-58-

Representative at the expense of the Former JetStar Holders. If a claim is asserted against the JetStar Stockholders’ Representative in connection with any action or inaction taken or not taken by it as agent for the Former JetStar Holders, it shall be entitled to full and complete indemnification from the Former JetStar Holders to the maximum extent permitted to a director of JetStar under the certificate of incorporation and bylaws of JetStar in existence immediately prior to the Closing. Any such amounts shall be paid from funds otherwise payable to the Former JetStar Holders under this Agreement or in connection herewith that are held by the Escrow Agent after the satisfaction of all indemnification claims made and such potential claims that may be made under Article 8. The JetStar Stockholders’ Representative shall have the right to refrain from taking any action if such person believes such funds may not be sufficient pending its request for agreements and funds from Former JetStar Holders for the provision of additional funds for such purpose and a response thereto acceptable to the JetStar Stockholders’ Representative.

     (c) Any costs or expenses incurred by the JetStar Stockholders’ Representative in his capacity as such under this Agreement, the Escrow Agreement or the Registration Rights Agreement, including reasonable fees and expenses of counsel to the JetStar Stockholders’ Representative, shall be paid (or reimbursed) from amounts due to the Former JetStar Holders from the Escrow Deposit or, in the event no amounts remaining in the Escrow Deposit are to be distributed to the former holders of JetStar Shares, from amounts (not to exceed $100,000 in the aggregate) due to Basic from the Escrow Deposit. Notwithstanding any other provisions of this Agreement, any such amounts due to the JetStar Stockholders’ Representative shall be withheld from amounts otherwise due to the Former JetStar Holders prior to distribution to such Former JetStar Holders. Basic shall instruct the Escrow Agent to pay (through advancement, reimbursement, or direct payment to a vendor) such fees and expenses, upon the reasonable request of the JetStar Stockholders’ Representative from time to time; provided that the aggregate amount of advances shall not exceed $100,000 at any time outstanding. The JetStar Stockholders’ Representative shall have the right to refrain from taking any action if such person believes such funds may not be sufficient pending its request for agreements and funds from Former JetStar Holders for the provision of additional funds for such purpose and a response thereto acceptable to the JetStar Stockholders’ Representative. The provisions of thisSection 9.16(c) shall not reduce the right of the JetStar Stockholders’ Representative to recover costs and expenses incurred by the JetStar Stockholders’ Representative in connection with the defense of any Third Party Claim as contemplated bySection 8.5(c)(i).

     SECTION 9.17NO THIRD-PARTY LIABILITY. This Agreement may only be enforced against the named parties hereto. All claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement (including any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement), may be made only against the entities that are expressly identified as parties hereto; and no officer, director, stockholder, employee or affiliate of any party hereto (including any person negotiating or executing this Agreement on behalf of a party hereto) shall have any liability or obligation with respect to this Agreement or with respect to any claim or cause of action (whether in contract or tort) that may arise out of or relate to this Agreement (including a representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement).
