The RECEIVING PARTY shall not use INFORMATION received for any purpose other than provided for in this Agreement.

The foregoing obligations of this Article 5.1 shall not apply to INFORMATION or to any part thereof for which the RECEIVING PARTY proves that it

was in the public domain at the time of disclosure to the RECEIVING PARTY by the DISCLOSING PARTY;

after such disclosure became part of the public domain through no act or omission on the part of the RECEIVING PARTY;

was in the RECEIVING PARTY’S possession prior to disclosure by the DISCLOSING PARTY;

was received by the RECEIVING PARTY from any third party having the right to disclose such information without direct or indirect secrecy obligation to the DISCLOSING PARTY;

A particular INFORMATION shall not be excluded from confidentiality merely because it is embraced by more general INFORMATION qualifying for exclusion, unless the INFORMATION itself qualifies for exclusion.

The obligations of this Article V shall remain in force for ten (10) years from the EFFECTIVE DATE or until five (5) years after the expiration of this Agreement, whichever periods ends later.

BAYER warrants that it has the legal power to license out KNOW-HOW to CHROMDEX.

CHROMADEX has been demonstrated the successful operation of KNOW-HOW by BAYER. BAYER makes no warranties whatsoever with reference to KNOW-HOW or their freedom from infringement of any patent or other similar rights of any third party. It is the sole responsibility of CHROMADEX to commercialize and/or practice KNOW-HOW and PATENTS in the TERRITORY. BAYER represents that, at the EFFECTIVE DATE, it has not received written notice of and is not in actual knowledge of any infringement of any third party’s rights by commercializing or practicing KNOW-HOW and PATENTS.

BAYER shall not be liable to CHROMADEX for any losses, expenses, costs, direct damages, sequential or consequential damages including environmental damages, or personal injury or property damage arising out of or resulting from the use of any information so disclosed by BAYER for or to CHROMADEX, since the measurements and sales are the sole risk of CHROMADEX.

BAYER agrees to prosecute or have prosecuted by BAYER AG the PATENTS up to the grant thereof, to maintain the PATENTS and to defend same against attack from third parties. If BAYER or BAYER AG intends to abandon any of the PATENTS it will inform CHROMADEX accordingly in writing and at CHROMADEX’s request transfer such PATENTS to CHROMADEX. CHROMADEX will bear the costs of the transfer of the patent concerned.

The parties will inform each other of any infringement of the PATENTS of which they become aware. BAYER or BAYER AG will take either judicial or extrajudicial action against any infringers of the PATENTS if BAYER or BAYER AG consider the action involved to be sufficiently likely to succeed and BAYER or BAYER AG will bear the costs of any action taken.

If BAYER and BAYER AG decide not to take action against an infringer the parties will jointly decide what procedure to take. CHROMADEX can only take independent action against the infringer with BAYER’S prior consent, which consent will not be unreasonably withheld or delayed.

Unless otherwise agreed between the parties, any damages or compensation possibly to be paid by the infringer shall be applied first to the each party to this Agreement taking action against the infringement concerned and thus bearing the corresponding costs, then to CHROMADEX to the extent of the damages sustained by CHROMADEX and caused by the infringement, and then, if there would be any damages or compensation possibly to be paid by the infringer left over, to both parties in equal shares.

CHROMADEX shall not challenge the validity of PATENTS or support third parties in such a challenge.

This Agreement shall become effective at the EFFECTIVE DATE and shall be in force thereafter unless otherwise terminated as provided for herein, during a period of ten (10) years after the EFFECTIVE DATE.

This Agreement shall be automatically renewed for successive periods of two (2) years each unless written notice of termination is given by one of the parties to the other at least six (6) months prior to the expiration of the original ten (10) year period or the expiration of one of the successive two (2) year periods. Any license granted pursuant to this Agreement shall not survive termination of this Agreement.

This Agreement may be terminated prematurely, as provided for below, upon the failure of either CHROMADEX or BAYER to fulfill its obligations under this Agreement. The party aggrieved by such default shall give to the other party notice of such default (such notice to refer specifically to the aggrieved party’s intention to terminate this Agreement in the event of continued default) and, if after two (2) months from the date of such notice the defaulting party has failed or refused to remedy such default, this Agreement shall be open to termination by notice given to the defaulting party not later than four (4) months after the date of notice of such default, and such termination shall be without prejudice to any other rights or claims the aggrieved party may have against the defaulting party.

BAYER is entitled to terminate this Agreement prematurely by giving notice to CHROMADEX in the event that CHROMADEX fails to generate product sales of at least 50,000 USD (fifty thousand U. S. Dollar) by exploiting the license granted under this Agreement within two (2) years after the EFFECTIVE DATE or in the event that CHROMADEX becomes bankrupt, insolvent or liquidated or if the business of CHROMADEX is placed in the hands of a receiver, assignee or trustee in bankruptcy, whether by the voluntary act of CHROMADEX or otherwise.

Termination of the Agreement by reason of expiration or express termination as provided for in this Article VIII shall be without prejudice to any rights or obligations of the parties hereto which have accrued as of the date of expiration or express termination.

If this Agreement is terminated pursuant to Article 8.2 or 8.3, such termination shall have the effect of terminating the rights of CHROMADEX except that any work in process or any contract resulting from a firm bid issued prior to the effective termination date may be completed by CHROMADEX under the terms and conditions of this Agreement.

The parties’ performance of their respective obligations hereunder shall be subject to force majeure, including, but not limited to, acts of God, insurrections, riots, wars and warlike operations, acts of any public enemy or any similar occurrence beyond the reasonable unavoidable control of the respective party.

However, the party affected by force majeure as set forth in this Article 9.1 shall use its best efforts to avoid, remove or cure such circumstances. Any party temporarily excused from performance hereunder by any such circumstances shall resume performance with utmost dispatch when such circumstances are removed or cured. Any party claiming such circumstances as an excuse for delay in performance shall give prompt notice in writing thereof to the other party.

This Agreement and Annexe I, II and III attached hereto constitute the final expression of the entire understanding between CHROMADEX and BAYER relating to the subject matter hereof and may not be contradicted by evidence of any prior agreement or of a contemporaneous oral agreement. No change in, addition to or waiver of the terms and provisions hereof shall be binding upon either CHROMADEX or BAYER unless confirmed in writing by the party to be charged.

This Agreement and the license granted herein shall, unless otherwise provided for herein, not be assignable by either party without the prior written consent of the other party which consent shall not be unreasonably withheld or delayed.

The invalidity or unenforceability of one provision of this Agreement will not cause the invalidity of the whole Agreement. The parties will in such case agree on a substitution of such invalid or unenforceable provisions by a valid and enforceable one, that resembles as closely as possible the economic effect of the invalid or unenforceable one, that resembles as closely as possible the economic effect of the invalid or unenforceable provision.

The parties agree that the validity of this Agreement and their respective rights and obligations under it shall be governed by the laws of the Federal Republic of Germany.

The parties are obligated to undertake all reasonable efforts in order to solve in an amicable way any controversy arising in connection with this Agreement.

Any controversy arising in connection with this Agreement that cannot be settled amicably shall be finally settled by arbitration according to the rules of settlement and arbitration of the International Chamber of Commerce. Arbitration shall be held in Zurich. The law of the Federal Republic of Germany shall apply to such arbitration.

The correspondence addresses will be:

In case of CHROMADEX and in case of BAYER

or as to each party, such other address for such party as it shall have furnished theretofore in writing to the other party.

If sent by mail, telefax, telex or telegram, the date of mailing or transmission shall be the date on which such notice or request is sent.

Vibrio fischeri’s sensitivity (limits of detection) against Ginkgolic acids and Aristolochic acids: CHROMADEX shall establish the detection limits required for the assay based upon regulatory and market need. BAYER/CHROMADEX shall test vibrio fischeri’s capability for meeting these limits as the first step of the project, therefore establishing a go/no-go situation. Assuming that vibrio fischeri’s bioluminescence will be inhibited by Ginkgolic acids and Aristolochic acids with a suitable limit of detection CHROMADEX can proceed with further development of the method.

Develop Standardized Methods: CHROMADEX will develop standardized testing protocols and materials for all required Ginkgolic acids and Aristolochic acids in priority order according to the “Top 20 list of nutritional supplements/natural drugs” (see Exhibit 1 of this ANNEX II).
