Within thirty (30) days of execution of the Agreement: (a)	provide BRAD with an external paint scheme agreed on by the parties; and (b)	select interior colours (from BRAD's standard colours). 	Failure of Buyer to comply with these requirements may result in an increase in price, a delay in delivery of the Aircraft, or both. 7.2	On or before execution of this Agreement Buyer shall notify BRAD in writing of the BFE (if any) that Buyer wishes to have incorporated into each Aircraft. Buyer shall also provide details of: a.	weights and dimensions of the BFE; b.	test equipment or special tools required to incorporate the BFE; and c.	any other information BRAD may reasonably require.

BRAD shall only be responsible for the fitment and testing of the BFE in the Aircraft using reasonable care and good manufacturing practices, in accordance with Buyer's written detailed description of the dimensions and weight of such BFE. Buyer shall also furnish information necessary for its proper storage, fitment, servicing, maintenance and operation and availability of test equipment or special tools; f.	BRAD SHALL HAVE NO LIABILITY OR OTHER OBLIGATIONS AND IS HEREBY RELIEVED OF ANY LIABILITY, WARRANTY OR OTHER OBLIGATION WITH RESPECT TO THE BFE AND BUYER HEREBY WAIVES ALL EXPRESS OR IMPLIED WARRANTIES OR CONDITIONS INCLUDING THOSE OF MERCHANTABILITY OR FITNESS OR OTHERWISE AND ALL OTHER LIABILITY (STRICT OR OTHERWISE) ON THE PART OF BRAD, BE IT IN FACT, IN LAW, IN CONTRACT, OR IN TORT (INCLUDING WITHOUT LIMITATION THE ACTIVE, PASSIVE OR IMPUTED NEGLIGENCE OR STRICT PRODUCTS LIABILITY OF BRAD OR ITS AFFILIATES), OR OTHERWISE, IN CONNECTION WITH THE BFE OR ITS DESIGN, SUITABILITY, USE OR OPERATION. 7.4	If at any time between receipt of the BFE by BRAD and the Delivery Date, it is reasonably determined by BRAD that an item of BFE supplied does not meet the standards and requirements described above or its fitment, integration and testing in the Aircraft or Aircraft systems create delays in the manufacturing or certification process, then such BFE may be removed and replaced by other BFE or by BRAD's equipment. Any costs associated with the removal, refitment, replacement, testing, certification and/or delays in the Delivery Date of the Aircraft shall be borne by Buyer unless a specific change made by BRAD results in previously acceptable BFE being refused. 7.5	In the event that the delivery of an Aircraft is delayed due to any delay caused by Buyer's failure to: a.	deliver or have BFE delivered by the date required; b.	ensure satisfactory design, suitability, use or operation of the BFE; c.	furnish or obtain applicable BFE data; d.	perform any adjusting, calibrating, retesting or updating of BFE; e.	furnish or obtain any approvals in compliance with the provisions of this Article; or f.	comply with the conditions of this Article; 	then BRAD agrees to discuss with Buyer the steps to be taken to minimize, cure, eliminate or work around the delay, but any delay incurred shall be the responsibility of Buyer and Buyer shall pay to BRAD any costs and expenses reasonably incurred by BRAD due to such delay. 7.6	Should there be a delay in delivery caused either by a failure of Buyer described in Article 7.5, or by an event to which reference is made in Article 13.0 in connection with the BFE, and if such delay cannot reasonably be minimized, cured, eliminated or worked around by agreement of the parties, Buyer agrees that BRAD may deliver the Aircraft without installing the unapproved, delayed or nonconforming BFE, and Buyer agrees to take delivery of and pay for the Aircraft. 7.7	If this Agreement is terminated in whole or in part in accordance with the provisions hereof BRAD may elect to, by written notice to Buyer, either: 		a.	if concurrence is received from Buyer, purchase the BFE ordered by Buyer and/or received by BRAD at the invoice price paid by Buyer; or 		b.	return the BFE to Buyer Free Carrier (Incoterms 1990) BRAD's plant, or such other place that BRAD may designate.

Should the inspection reveal a defect or discrepancy which from Buyer's standpoint is not a material defect the cost correction of which would be disproportionate to the impact of such defect or discrepancy or Buyer's operation the parties agree to discuss to resolve the issue in a manner satisfactory to both parties. To the extent necessary to demonstrate to Buyer such correction, BRAD shall perform one (1) or more further acceptance flights. 	9.6.2	If any material defect or discrepancy in the Aircraft is revealed by Buyer's ground inspection or flight test, and BRAD is not able to promptly correct such defect or discrepancydiscrepenacy then BRAD and Buyer will cooperate to effect acceptance and delivery of such Aircraft following correction of such defect in a timely manner satisfactory to both parties. 9.7	Upon completion of the ground inspection and acceptance flight of the Aircraft and correction of any material defects or discrepancies: (a)	Buyer will sign a Certificate of Acceptance (in the form of Exhibit I hereto) for the Aircraft. Execution of the Certificate of Acceptance by or on behalf of Buyer shall be evidence of Buyer having examined the Aircraft and found it in accordance with the provisions of this Agreement. The date of signature of the Certificate of Acceptance shall be the "Acceptance Date"; (b)	BRAD will supply a TC Certificate of Airworthiness for Export; and (c)	Buyer shall pay BRAD the balance of the Aircraft Purchase Price and any other amounts due, at which time BRAD shall cause de Havilland Inc., the manufacturer, to issue an FAA form Bill of Sale and a bill of sale (in the form of Exhibit II hereto) passing to Buyer good title to the Aircraft free and clear of all liens, claims, charges and encumbrances except for those liens, charges or encumbrances created by or claimed through Buyer (collectively the "Bill of Sale"). The date on which BRAD delivers the Bill of Sale and Buyer takes delivery of the Aircraft shall be the "Delivery Date". 	Delivery of the Aircraft shall be evidenced by the execution and delivery of the Bill of Sale and of the Certificate of Receipt of Aircraft (in the form of Exhibit III hereto). 9.8	Provided that BRAD has met all of its obligations under this Article 9, should Buyer not accept, pay for and take delivery of any of the Aircraft within ten (10) calendar days after the end of the Acceptance Period of such Aircraft, Buyer shall be deemed to be in default of the terms of this Agreement. 9.9	Provided that BRAD has met all material obligations under this Article 9, Buyer shall promptly, upon demand, reimburse BRAD for all costs and expenses reasonably incurred by BRAD as a result of Buyer's failure to accept or take delivery of the Aircraft, including but not limited to reasonable amounts for storage, insurance, taxes, preservation or protection of the Aircraft. Provided that BRAD has met all of its obligations under this Article 9, should Buyer not accept, pay for and/or take delivery of any one of the Aircraft by the end of the Acceptance Period, the present Agreement can be terminated pursuant to Article 16.2 herein. ARTICLE 10 - TITLE AND RISK 10.1	Title to the Aircraft and risk of loss of or damage to the Aircraft passes to Buyer when BRAD presents the Bill of Sale to Buyer on the Delivery Date. 10.2	If, after transfer of title on the Delivery Date, the Aircraft remains in or is returned to the care, custody or control of BRAD, Buyer shall retain risk of loss of, or damage to the Aircraft and for itself and on behalf of its insurer(s) hereby waives and renounces to, and releases BRAD and any of BRAD's affiliates from any claim, whether direct, indirect or by way of subrogation, for damages to or loss of the Aircraft arising out of, or related to, or by reason of such care, custody or control.

ARTICLE 13 - EXCUSABLE DELAY 13.1	In the event of a delay on the part of BRAD in the performance of its obligations or responsibilities under the provisions of this Agreement due directly or indirectly to a cause which is beyond the reasonable control or without the fault or negligence of BRAD (an "Excusable Delay"), BRAD shall not be liable for, nor be deemed to be in default under this Agreement on account of such delay in delivery of the Aircraft or other performance hereunder and the time fixed or required for the performance of any obligation or responsibility in this Agreement shall be extended for a period equal to the period during which any such cause or the effect thereof persist. Excusable Delay shall be deemed to include, without limitation, delays occasioned by the following causes: (a)	force majeure or acts of God; (b)	war, warlike operations, act of the enemy, armed aggression, civil commotion, insurrection, riot or embargo; (c)	fire, explosion, earthquake, lightning, flood, draught, windstorm or other action of the elements or other catastrophic or serious accidents; (d)	epidemic or quarantine restrictions; (e)	any legislation, act, order, directive or regulation of any governmental or other duly constituted authority; (f)	strikes, lock-out, walk-out, and/or other labour troubles causing cessation, slow-down or interruption of work; (g)	lack or shortage or delay in delivery of supplies, materials, accessories, equipment, tools or parts, provided another reasonable and practicable alternative source or measure to avoid such were not available to BRAD; (h)	delay or failure of carriers, subcontractors or suppliers to deliver parts, products, data or services for any reason whatsoever, provided same are ordered in a timely manner; and (i)	delay in obtaining any airworthiness approval or certificate, or any equivalent approval or certification, by reason of any law or governmental order, directive or regulation or any change thereto, or interpretation thereof, by a governmental agency, the effective date of which is subsequent to the date of this Agreement, or by reason of any change or addition made by BRAD or its affiliates or requested by a governmental agency to the compliance program of BRAD or of its affiliate, or any part thereof, as same may have been approved by TC, or change to the interpretation thereof to obtain any such airworthiness approval or certificate. 13.2	(a)	If BRAD concludes, based on its appraisal of the facts and normal scheduling procedures, that due to Excusable Delay delivery of the Aircraft will be delayed for more than twelve (12) months after the originally Scheduled Delivery Date or any revised date agreed to in writing by the parties, BRAD shall promptly notify Buyer in writing and either party may then terminate this Agreement with respect to the Aircraft by giving written notice to the other within fifteen (15) days after receipt by Buyer of BRAD's notice. 	(b)	If, due to Excusable Delay, delivery of any Aircraft is delayed for more than twelve (12) months after the Scheduled Delivery Date, either party may terminate this Agreement with respect to such Aircraft by giving written notice to the other within fifteen (15) days after the expiration of such twelve (12) month period. 13.3	Termination under Article 13.2 shall discharge all obligations and liabilities of Buyer and BRAD hereunder with respect to such delayed Aircraft and all related undelivered items and services, except that BRAD shall promptly repay to Buyer, and BRAD's sole liability and responsibility shall be limited to the repayment to Buyer, of all advance payments for such Aircraft received by BRAD less any amount due by Buyer to BRAD. 13.4	The termination rights set forth in Article 13.2 are in substitution for any and all other rights of termination or contract lapse arising by operation of law in connection with Excusable Delays. 13.5	[CONFIDENTIAL TREATMENT REQUESTED]. ARTICLE 14 - NON-EXCUSABLE DELAY 14.1	If delivery of the Aircraft is delayed by causes not excused under Article 13.1 (a "Non-Excusable Delay"), BRAD shall pay Buyer, [CONFIDENTIAL TREATMENT REQUESTED for any such delayed Aircraft. 14.2	THE LIQUIDATED DAMAGES PAYABLE IN ACCORDANCE WITH ARTICLE 14.1 AND BUYER'S RIGHT OF TERMINATION UNDER ARTICLE 14.3 CONSTITUTE BUYER'S EXCLUSIVE REMEDY AND RIGHT FOR NON-EXCUSABLE DELAY, INCLUDING A COMPLETE FAILURE TO DELIVER, FOR ANY REASON WHATSOEVER OTHER THAN BRAD'S WILLFUL MISCONDUCT. BUYER WAIVES, RELEASES AND RENOUNCES ALL OTHER CLAIMS, RIGHTS AND REMEDIES, AT LAW OR IN EQUITY, WHETHER BASED ON CONTRACT (INCLUDING WITHOUT LIMITATION WARRANTY), TORT (WHETHER OR NOT ARISING FROM THE ACTIVE, PASSIVE OR IMPUTED NEGLIGENCE OF BRAD OR DE HAVILLAND INC.) OR THE STRICT PRODUCTS LIABILITY OF BRAD OR DE HAVILLAND INC. OR OTHERWISE, FOR (a) ANY COSTS INCURRED BY BUYER IN SECURING TEMPORARY OR PERMANENT REPLACEMENT AIRCRAFT, (b) ANY FINANCING, TAX, PERSONNEL, FACILITY OR OTHER COSTS OR DAMAGES INCURRED BY BUYER RELATING TO DELIVERY OR NON-DELIVERY OF THE AIRCRAFT, INCLUDING BUT NOT LIMITED TO EXPENSES FOR PILOT AND GROUND CREW TRAINING, MAINTENANCE FACILITIES, SCHEDULING AND PILOT TIME, OR (c) ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES, INCLUDING WITHOUT LIMITATION LOSS OF USE, LOSS OF REVENUE OR LOSS OF PROFIT. 14.3	Any right Buyer might otherwise have to refuse to accept delivery of an Aircraft when offered by BRAD for inspection and acceptance following a Non-Excusable Delay is included within the rights and remedies for which the liquidated damages provided pursuant to Article 14.1 are the exclusive right and remedy. Buyer will not have the right to refuse to take delivery of any Aircraft because of a Non-Excusable Delay unless and until the aggregate duration of the Non-Excusable Delay for such Aircraft exceeds sixty (60) days. If BRAD has not offered an Aircraft for inspection and acceptance before the end of that sixty (60) day period, Buyer may terminate the Agreement as to such Aircraft by giving notice to BRAD. Buyer shall, effective upon such termination, be entitled to recover from BRAD, as liquidated damages and not as a penalty, the aggregate amount of liquidated damages calculated under Article 14.1 to the date of termination. In addition BRAD shall promptly repay to Buyer all advance payments for such Aircraft plus daily simple interest thereon from the date of receipt to the date of repayment at the prime rate charged by the National Bank of Canada from time to time, calculated and compounded monthly. ARTICLE 15 - LOSS OR DAMAGE 15.1	In the event that prior to the Delivery Date of any Aircraft, the Aircraft is lost, destroyed or damaged beyond repair due to any cause, BRAD shall promptly notify Buyer in writing. Such notice shall specify the earliest date reasonably possible, consistent with BRAD's other contractual commitments and production schedule, by which BRAD estimates it would be able to deliver a replacement for the lost, destroyed or damaged Aircraft. This Agreement shall automatically terminate as to such Aircraft unless Buyer gives BRAD written notice, within thirty (30) days of BRAD's notice, that Buyer desires a replacement for such Aircraft. If Buyer gives such notice to BRAD, the parties shall execute an amendment to this Agreement which shall set forth the Delivery Date for such replacement aircraft and corresponding new replacement Aircraft Purchase Price; provided, however, that nothing herein shall obligate BRAD to manufacture and deliver such replacement aircraft if it would require the reactivation or acceleration of its production line for the model of aircraft purchased hereunder. The terms and conditions of this Agreement applicable to the replaced Aircraft shall apply to the replacement aircraft. ARTICLE 16 - TERMINATION 16.1	This Agreement may be terminated, in whole or in part, with respect to any or all of the Aircraft before the Delivery Date by BRAD or Buyer by notice of termination to the other party upon the occurrence of any of the following events: (a)	a party makes an assignment for the benefit of creditors or admits in writing its inability to pay its debts or generally does not pay its debts as they become due; or (b)	a receiver or trustee is appointed for a party or for substantially all of such party's assets and, if appointed without such party's consent, such appointment is not discharged or stayed within thirty (30) calendar days thereafter; or (c)	proceedings or action under any law relating to bankruptcy, insolvency or the reorganization or relief of debtors are instituted by or against a party, and, if contested by such party, are not dismissed or stayed within thirty (30) calendar days thereafter; or (d)	any writ of attachment or execution or any similar process is issued or levied against a party or any significant part of its property and is not released, stayed, bonded or vacated within thirty (30) calendar days after its issue or levy. 16.2	In addition, this Agreement may be terminated, in whole or in part, before the Delivery Date with respect to any or all undelivered Aircraft (a)	as otherwise provided in this Agreement; or (b)	by BRAD, if Buyer is in default or breach of any material term or condition of this Agreement and Buyer does not cure such default or breach within forty-five (45) calendar days after receipt of notice from BRAD specifying such default or breach. (c)	by Buyer, if BRAD is in default or breach of any material term or condition of this Agreement and such breach remains uncured for a period of forty-five (45) calendar days following receipt of a notice from Buyer specifying the nature of default or breach. 16.3	In case of termination of this Agreement under Article 9.9, or by BRAD pursuant to Articles 16.1 or 16.2: (a)	all rights (including property rights), if any, which Buyer or its assignee may have or may have had in or to this Agreement or any or all of the undelivered Aircraft shall become null and void with immediate effect; (b)	BRAD may sell, lease or otherwise diespose of such Aircraft to another party free of any claim by Buyer; and (c)	all amounts paid by Buyer with respect to the applicable undelivered Aircraft shall be retained by BRAD and shall be applied against the costs, expenses, losses and damages incurred by BRAD as a result of Buyer's default and/or the termination of this Agreement. Buyer hereby acknowledges and recognizes that BRAD shall have all rights permitted by law to recover from Buyer such costs, expenses, losses and damages and, in any event, such costs, expenses, losses and damages will aggregate not less than the amount retained by BRAD pursuant to this Article 16.4 (c). 16.4	Subject to Article 14.1, in the event of termination of this Agreement by Buyer, Buyer's sole rights, remedies and recourses against BRAD and BRAD's obligations to Buyer shall be limited to only the return by BRAD of those amounts paid by Buyer to BRAD hereunder on account of the undelivered Aircraft.

Whether or not BRAD intervenes, BRAD shall be entitled at any stage of the proceedings to assume or control the defense. Buyer's remedy and BRAD's obligation and liability are further conditional upon BRAD's prior approval of Buyer's payment or assumption of any liabilities, expenses, damages, royalties or costs for which BRAD may be held liable or responsible. 18.4	THE INDEMNITY, OBLIGATIONS AND LIABILITIES OF BRAD AND REMEDIES OF BUYER SET OUT IN THIS ARTICLE ARE EXCLUSIVE AND ACCEPTED BY BUYER TO BE IN LIEU OF AND IN SUBSTITUTION FOR, AND BUYER HEREBY WAIVES, RELEASES AND RENOUNCES, ALL OTHER INDEMNITIES, OBLIGATIONS AND LIABILITIES OF BRAD AND OF ITS AFFILIATES AND ALL OTHER RIGHTS, REMEDIES AND CLAIMS, INCLUDING CLAIMS FOR DAMAGES, DIRECT, INCIDENTAL OR CONSEQUENTIAL, OF BUYER AGAINST BRAD AND ITS AFFILIATES EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE, WITH RESPECT TO ANY ACTUAL OR ALLEGED PATENT INFRINGEMENT BY THE AIRCRAFT OR ANY INSTALLED SYSTEM, ACCESSORY, EQUIPMENT OR PART.

Bombardier Regional Aircraft Division: ___________________________	_______________________________ Glenn Johnson		Pierre Lortie V.P. Finance and C.F.O.	President 			_______________________________ 			Michel Bourgeois 			Vice President, Contracts APPENDIX I ECONOMIC ADJUSTMENT FORMULA 1.	Economic Adjustment will be calculated using the following Economic Adjustment Formula: 	PA = P1 - P0 	Where P1 = P0 [0.65 (L1/L0) + 0.35 (M1/M0) ] 2.0	In the Economic Adjustment Formula: a.	PA	=	Aircraft Price Adjustment; b.	P0	=	Base Price; c.	P1	=	Base Price adjusted to the time of delivery to Buyer using the formula set forth above; d.	L1	=	the delivery year index for labour obtained by calculating the arithmetic average of the labour indexes published by Statistics Canada in Labour Earnings and Hours, Table 3.1, for the fourth, fifth and sixth months prior to the month of delivery of the Aircraft; e.	L0	=	19.19, being the index for labour obtained by calculating the arithmetic average of the labour indexes published by Statistics Canada in Labour (Canada), Aircraft and Aircraft Parts, Code 321, Earnings and Hours, Table 3.1 for January, February and March, 1995; f.	M1	=	the delivery year index for material obtained by calculating as the arithmetic average of the material indexes published by the U.S. Department of Labor in Material (U.S.) Industrial Commodities, Producer Price Index, Table 6, for the fourth, fifth and sixth months prior to the month of delivery of the Aircraft.; g.	M0	=	124.3, being the index for material obtained by calculating the arithmetic average of the material indexes published by the U.S. Department of Labor in Material (U.S.) Industrial Commodities, Producer Price Index, Table 6 January, February and March, 1995. 3.	In the calculation of the Aircraft Price Adjustment: 	a.	All indices used in the calculations made to determine the factor to apply to P0, and the calculations themselves, will be to four significant digits; and 	b.	The Aircraft Price Adjustment will be corrected to the nearest dollar. 4.	In the event that at the time of Aircraft delivery BRAD is unable to determine the Aircraft Price Adjustment due to the unavailability of L1 or M1, then: 	a.	An interim Aircraft Price Adjustment amount will be calculated in accordance with the Economic Adjustment Formula utilizing the latest available delivery indexes and such amount shall be paid to BRAD in lieu of the Aircraft Price Adjustment of delivery; and 	b.	subsequent to delivery of the Aircraft and as soon as both L1 or M1 are available, BRAD will calculate the Aircraft Price Adjustment and will submit to Buyer a supplemental invoice for the amount due to BRAD or refund to Buyer the amount due Buyer, as appropriate. 5.

If an S1BOOKED acknowledgment is not sent within 24 hours by BRAD then Buyer shall resend the original message. 		Any document which has been properly received shall not give rise to any obligation unless and until the party receiving such document has properly transmitted in return an acknowledgment document according to SPEC 2000 Protocol. 	2.9.4.3	Systems Operations 		Buyer and BRAD, at their own expense, shall provide and maintain the equipment, software, services and testing necessary to effectively and reliably transmit and receive documents. 2.9.4.4	Validity of Documents 		Annex A Article 2.9.4 has been agreed to by Buyer and BRAD to evidence their mutual intent to create binding purchase and sale obligations pursuant to the electronic transmission and receipt of documents as described herein. 		Such documents properly transmitted pursuant to this Annex A Article 2.9.4 shall be considered, in connection with any transaction or any other agreement, to be a "writing" or "in writing" and shall be deemed for all purposes (a) to have been "signed" and (b) to constitute an "original" when printed from electronic files or records established and maintained in the normal course of business.

Providing, however, in the event that repetitive in-service failure occurs on the particular BRAD Part which is subsequently identified by BRAD on a repeated basis to be "no fault found," then BRAD and Buyer shall discuss and mutually agree a course of further action to help identify the problem. In the event the fault is ultimately confirmed to be a legitimate Warranty claim then the above mentioned costs incurred by BRAD and charged to Buyer shall be waived.

All terms herein and in the Agreement and not defined herein shall have the same meanings as in the Agreement. MAXIMUM ZERO FUEL WEIGHT AND MANUFACTURER'S EMPTY WEIGHT 1.0	The intent of this Letter Agreement is to confirm the progress BRAD/de Havilland has made recently towards providing 400 lbs of additional payload by increasing the maximum Zero Fuel Weight of the Dash 8 Series 202 (the "Aircraft") and reducing the Manufacturer's Empty Weight in the Buyer's configuration 2.0	At delivery the Aircraft will have at least 200 lbs of additional payload beyond that previously contemplated, in situations where the payload is structurally limited, if Buyer is prepared to delete two items of optional equipment. The two items, which BRAD believes are not required by FAR 121 and do not add value to your product are: (1) the Heavy Duty Battery option (824SO08070-1, a 47 lb penalty) and (2) the Cockpit Portable Oxygen Bottle (835CH00041, an 8lb penalty). With these two items and all other contingencies removed, the Manufacturer's Empty Weight of the Dash 8 Model 202 as currently configured for delivery to Buyer will total 2 3,378.4 lbs as set forth in Attachement 1, which ismore than 200 lbs less than previously indicated. 3.0	In addition, to reach the 400 lb target of additional payload target, de Havilland will undertake an extensive stress analysis program to determine the potential for further increases in maximum Zero Fuel Weight and reduction in empty weight. The results of this program will become available and a plan for implementation of these product improvements outlining the achievable results shall be presented to Buyer in January 1997. 4.0	THE PERFORMANCE GUARANTEES PROVIDED IN THIS LETTER AGREEMENT AND THE OBLIGATIONS AND LIABILITIES ON THE PART OF BRAD UNDER THE AFORESAID GUARANTEES ARE ACCEPTED BY BUYER AND ARE EXCLUSIVE AND IN LIEU OF, AND BUYER HEREBY WAIVES, RELEASES AND RENOUNCES ALL OTHER REMEDIES, WARRANTIES, GUARANTEES OR LIABILITIES, EXPRESS OR IMPLIED, WITH RESPECT TO THESE PERFORMANCE GUARANTEES CONCERNING EACH AIRCRAFT DELIVERED UNDER THE AGREEMENT, ARISING BY LAW OR OTHERWISE INCLUDING, WITHOUT LIMITATION, ANY OBLIGATION, LIABILITY, CLAIM OR REMEDY WHETHER OR NOT ARISING FROM NEGLIGENCE (WHETHER ACTIVE, PASSIVE OR IMPUTED) OF BRAD, ITS OFFICERS, EMPLOYEES, AGENTS OR ASSIGNEES, OR WITH RESPECT TO ANY IMPLIED WARRANTY OF FITNESS OR MERCHANTABILITY, ANY IMPLIED WARRANTY ARISING FROM COURSE OF PERFORMANCE, COURSE OF DEALING OR USAGE OF TRADE, LOSS OF USE, REVENUE OR PROFIT OR FOR ANY OTHER DIRECT, INDIRECT, INCIDENTAL OR CONSEQUENTIAL LOSSES OR DAMAGES. 5.0	THE FOREGOING LIMITATION OF LIABILITY DOES NOT APPLY TO ANY LOSSES, DAMAGES OR CLAIMS ARISING OUT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF BRAD OR OF ANY PERSON FOR WHOM BRAD IS IN LAW RESPONSIBLE AND NOTHING HEREIN CONTAINED SHALL CONSTITUTE OR BE DEEMED TO CONSTITUTE A WAIVER, RELEASE OR RENUNCIATION OF ANY SUCH LOSSES, DAMAGES OR CLAIMS. 6.0	BUYER AND BRAD AGREE THAT THIS LETTER AGREEMENT, INCLUDING BUT NOT LIMITED TO ARTICLE 3.0 ABOVE, HAS BEEN THE SUBJECT OF DISCUSSION AND NEGOTIATION AND IS FULLY UNDERSTOOD BY THE PARTIES HERETO AND THAT THE MUTUAL AGREEMENTS OF THE PARTIES SET FORTH IN THIS LETTER AGREEMENT WERE ARRIVED AT IN CONSIDERATION OF PROVISIONS CONTAINED IN THIS ARTICLE 8.AND THE OTHER PROVISIONS OF THIS LETTER AGREEMENT. 7.0	In the event of the termination of the Agreement, this Letter Agreement shall become automatically null and void. 8.0	The provisions of this Letter Agreement are personal to Buyer and shall not be assigned or otherwise disposed of by Buyer without the prior written consent of BRAD. 9.0	This Letter Agreement constitutes an integral part of the Agreement and subject to the terms and conditions contained therein.
