|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------

|4. | Termination for Cause:Upon default by either party in the performance of any material obligation in this Agreement, either party may give notice in writing to the other party and the defaulting party shall have thirty (30) days to cure the default. However, if the default is not cured within thirty (30) days, the non-defaulting party may terminate this Agreement by providing notice of termination, which shall take effect no earlier than ten (10) days from the receipt of such notice. Termination under this paragraph shall not relieve either party of an obligation existing upon the date of termination or relieve either party from liability for breach of this Agreement subject to the terms of this Agreement.

|5. | Exclusive Sale and Purchase; Exceptions; First Right of Refusal:
|-- | ----------------------------------------------------------------

| | a) | Customer  agrees that during the Term of this  Agreement  it will  purchase  and
direct its  Converters  to purchase  all of its global  requirements  of medical
grade adhesive tapes used in the manufacturing of external nasal dilators,  with
the exception of Items in Exhibit A.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | b) | If Customer develops or has an opportunity to obtain a new or modified external nasal dilator or any other product that requires the use of medical grade adhesives or tapes not included as Components in this Agreement, then Customer agrees to provide specifications, including but not limited to performance, color, adhesive, and price to 3M. 3M will then determine its ability to supply such medical grade adhesives or tapes. If 3M agrees to supply such new medical grade adhesives or tapes, then these new adhesives or tapes would become Components and would be added to Schedule 1 by addendum. Purchases of such new Components would be included in total purchases to determine if Customer meets minimum purchase quantities. If 3M cannot or does not choose to supply the requested new medical grade adhesives or tapes to Customer, then 3M
will provide such notice to Customer within 60 days and Customer can purchase the requested medical grade adhesives or tapes from another source. However, if no other supplier can supply medical grade adhesives or tapes that meet the specifications, and Customer changes the specifications in order to purchase a medical grade adhesive or tape for these new or modified products, then Customer agrees to give 3M Medical Specialties the first right of refusal to supply such adhesives or tapes using the new specifications under the same conditions described earlier in this paragraph. Customer reserves the right to determine if the 3M medical grade adhesive tapes meet the new or revised specifications.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | c) | During the Term 3M Medical Specialties Department will not supply finished external nasal dilators or Components for use in the manufacture of external nasal dilators to any third party(s) other than Customer and its Converters nor will 3M Medical Specialties sell nasal dilators in the retail market.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | d) | 3M agrees to give Customer a right of first refusal for any new tapes or adhesives 3M might develop which could be useful for external nasal dilators (New Components). Customer will have 60 days to commit to using such a New Component(s) and introducing a product containing such New Component(s) within eighteen (18) months. Customer agrees to provide to 3M, regular, timely progress reports regarding the development and introduction of new or modified products using these New Components. If satisfactory progress is not made by Customer toward introduction of such new or modified products, as determined solely by 3M, then 3M shall have the right to sell New Components, after notification to Customer in writing, to any other customer for any applications without exceptions. In like manner, if Customer decides to cease
efforts to develop and introduce new or modified products using New Components, then Customer shall immediately notify 3M of such decision in writing. 3M will then have the right to sell New Components to any other customer for use in any product without restrictions. If a third party approaches 3M for any New Components not already offered to Customer, with the intent to use the New Components in external nasal dilators, 3M will provide Customer with a right of first refusal to purchase such New Component under the terms proposed by such third party and Customer will have 60 days to accept or reject such offer. If Customer accepts the offer, then Customer commits to purchase and use New Component(s) in the same manner as described earlier in this paragraph.

|6. | Forecasts, Binding Purchase Orders, Minimum Purchase Requirement:  Throughout the Term of this Agreement, Customer shall deliver to 3M on a monthly basis a forecast showing its estimated requirements for Components stated in number of strips, for the succeeding two calendar quarters (Rolling Forecast). Customer, through its converters, will assist 3M in translating the number of required finished strips into the equivalent number of square yards of Components required to produce the forecasted strips. Customer agrees that it is bound to purchase, or to direct its Converters to purchase, the first 60 days of forecasted Component requirements in the months such quantities were forecast. Binding purchase orders for requirements for Components shall be placed at least twenty-eight (28) days in
advance of the requested ship date. If an order has been received and accepted by 3M for Components and Customers converter(s) request to alter the order quantity of Components or any original requested ship date(s) for Components, 3M will not be obliged to accept such requests without prior approval of Customer and agreement by 3M. 3M will not be obliged to fulfill orders received less than 28 days from the requested ship date or for quantities more than 10% above the applicable Rolling Forecast. If however, Component requirements exceed 10% of Rolling Forecast, 3M shall meet with Customer to discuss if and how Customers production needs can be met. 3M will use reasonable efforts to meet such increased requirements.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|7. | Use of Name and Trademarks:Neither party will make any use whatsoever of the other partys name without its written permission. The decision to grant such permission is within sole discretion of the non-requesting party. Neither party will use or reproduce any of the other partys trademarks or logos in any manner without prior written approval. To request this approval, the requesting party must forward to the other party a complete and accurate specimen copy of the proposed use. The non-requesting party agrees to reply to the requesting party within thirty (30) days of receipt of such proposed use. Any permitted use extends only to authorized materials. 3M agrees to keep prices, forecast volumes, quantity of purchases and other material information related to this Agreement confidential
during the Term and for a period of two (2) years thereafter.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|8. | Other Terms and Conditions:Payment shall be according to the price set forth on Schedule 1 subject to the following. In each twelve-month period during the Term, the first period beginning upon the first day of the month of the Effective Date and ending twelve months thereafter, the Customer alone or together with its Converters shall purchase Components in an amount equal to at least 95% of the dollar value of Components purchased during the previous 12 month period (the first 12 month period in the Term shall be measured against the 12 month period prior to the Effective Date) (Minimum Purchase Requirement). In the event Customer, together with its Converters do not purchase the Minimum Purchase Requirement in any successive twelve-month period of the Term, pricing for the subsequent 12 month period
shall revert back to the order volume prices based on unit volume per order as shown in Schedule 1. Failure to purchase the Minimum Purchase Requirement shall not constitute a breach of this agreement. A price change will not affect any order properly placed before the effective date of such change. Customer shall direct its Converters to make payment within 30 days of the date of invoice. 3M reserves the right to not ship Components to any Converter whose accounts payable for Components are not current. The price for product set forth in Schedule 1 includes the cost of standard freight to one destination in the U.S. 3M and Customer will work together in good faith to try to find opportunities for reducing the cost of Customers external nasal dilators that use Components.

Risk of loss passes to Customer when Components are delivered to designated ship-to dock. For all Components contained in any single shipment, title passes to Customers Converters only when Customers Converters have fully paid for the shipment.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|16. | Component Discontinuance:3M may discontinue its production or sale of Components at any time during the Term of this Agreement if 3M has reasonable grounds to believe the Components or Customers products that use Components present a serious health, safety or environmental risk.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|17. | Miscellaneous:
|--- | --------------

| | a) | Insurance:Customer will maintain a liability insurance program covering such risks (including, but not limited, to products liability and contractual liability) as are appropriate in accordance with the sound business practice and Customers obligations under this Agreement, including, but not limited to, at least $5,000,000 in product liability and $5,000,000 in general liability coverage. At the request of 3M, Customer shall provide a certificate of insurance evidencing the existence of these coverages on an annual basis.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b) | Events of excused performance:Neither 3M nor Customer shall be considered in default or be liable to the other for any delay beyond the reasonable control of such party, including, but not limited to, acts of God, explosion, earthquake, fire, flood, war whether declared or not, accident, strikes, labor disturbances, inability to procure supplies from third party vendors, sabotage, or order or decrees of any court or action of a governmental authority. If such delay continues for a period of more than 30 consecutive days Customer is relieved of its obligation to purchase exclusively from 3M for the period of 3Ms inability to supply and such longer period as may be reasonably necessary to secure a supply of similar components from a third party. 3M agrees to use reasonable commercial efforts to
help Customer identify such a supplier.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | c) | No assignment or delegation:Neither this Agreement nor any of the rights and obligations of a party hereunder shall be assigned, delegated, sold, transferred, sublicensed or otherwise disposed of, by operation of law or otherwise, to any third party without the prior written consent of the other party not to be unreasonably withheld; provided, however, that either party may, without such consent, assign this Agreement and its rights and obligations hereunder in connection with the sale of all or substantially all of its assets related to the business for the ingredients or the products, or in the event of its merger or consolidation or change in control or similar transaction. This paragraph does not prevent Customer from using a designated converter to process some or all of Components for
Customer.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | d) | Notices:Any notice, order or other communication required by this Agreement must be in writing, sent by first class mail or faster written means, and addressed to the address listed on Attachment 1. A party may designate in writing a substitute address.

| | e) | Entire agreement; no waiver.This Agreement, the schedules attached hereto, as well as any 3M Component specifications, state the complete understanding between 3M and Customer on this subject and replace any statements, communications or understandings, whether oral or written, made before, during or after this Agreement is signed. Customer or its Converters may place orders under this Agreement using Customers or Converters regular purchase order form. The only function of such purchase order shall be to communicate the quantity of Components desired and any delivery instructions. Any other terms on such forms are void and of no effect. This Agreement cannot be modified except in wilting, signed by both parties. No sales representative of 3M may orally or in writing modify this Agreement. A
course of dealing or of performance or usage of trade does not effect a waiver or modification unless ratified in writing. A partys failure to exercise a right in one instance does not waive that partys right to later exercise that right.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | f) | Governing law and venue:Any questions, claims or disputes concerning or related to this Agreement are governed by the laws of Minnesota, notwithstanding any conflict of law principle to the contrary. The parties consent to jurisdiction and venue in the State of Minnesota.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | g) | Converters:It is acknowledged and agreed that Customer shall not be liable for the performance of any obligation that may be undertaken by any of the Converters to 3M in connection with the purchase of Components pursuant to this agreement or otherwise including, without limitation, the payment for Components pursuant to any orders placed by such Converters with 3M. Not withstanding the foregoing, Customer agrees to cooperate with 3M and render all assistance that may be reasonably requested with respect to any default by Converter in connection with its purchase of Components from 3M.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | h) | National Account Representation:3M agrees during the term of the agreement to provide Customer with National Account or similar status and to designate individual(s) where one or more of their responsibilities is to represent 3M and be a primary contact person for Customers staff for, but not limited to the following purposes:  new business opportunities, periodic forecast submissions, material lead-time and delivery or quantity Issues; etc.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | i) | Both parties agree not to disclose the terms or existence of this agreement to any third party, other than Customers Converters, except to the extent such disclosure is required by law or a valid court order.
