ARTICLE 4

ROYALTIES

In consideration of the license rights granted by ZALICUS to ANABIOS under this Agreement, ANABIOS will make to ZALICUS the following payments specific to each LICENSED PRODUCT:

4.1 Prior to ANABIOS having recovered its development costs for a particular LICENSED PRODUCT (the “DEVELOPMENT COSTS”), and to be documented as indicated in Article 6 of this AGREEMENT, ANABIOS will pay ZALICUS 6% of NET SALES that ANABIOS will receive for such LICENSED PRODUCT or, in case of sublicensing of a LICENSED PRODUCT to THIRD PARTIES, ANABIOS will pay ZALICUS 6% of any and all proceeds that ANABIOS will receive from SUBLICENSEE(S) related to the LICENSED PRODUCT, including amounts received by ANABIOS from SUBLICENSEES on achievement by the SUBLICENSEE of the milestones described in Article 5 below. All payments by ANABIOS to ZALICUS will continue until the last to expire of the PATENT RIGHTS, on a country by country basis.

4 After ANABIOS has recovered its development costs for a given LICENSED PRODUCT, ANABIOS will pay ZALICUS 12% of NET SALES that ANABIOS will receive for the LICENSED PRODUCT or, in case of sublicensing of the LICENSED PRODUCT to THIRD PARTIES, ANABIOS will pay ZALICUS 12% of any and all proceeds that ANABIOS will receive from SUBLICENSEE(S) related to the LICENSED PRODUCT, including amounts received by ANABIOS from SUBLICENSEES on achievement by the SUBLICENSEE of the milestones described in Article 5 below. All payments by ANABIOS to ZALICUS will continue until the last to expire of the PATENT RIGHTS, on a country by country basis.

4.3 In the event a LICENSED PRODUCT is SOLD for other than cash, then such SALE must be in an arms-length transaction at market-value and the royalty to be paid, if determined by ZALICUS to be below fair market value, will be determined based upon a valuation conducted by a nationally-recognized and mutually agreed upon accounting firm (the “AUDIT FIRM”), the costs of which will be equally shared by the PARTIES. ANABIOS will not SELL LICENSED PRODUCTS for no consideration or solely in exchange for property rights beneficial to ANABIOS for which ZALICUS receives less than market value intended hereunder for the LICENSED PRODUCTS.

4.4 In the event that a LICENSED PRODUCT is marketed in combination with any other product and is not separately priced, the earned royalty for such LICENSED PRODUCT shall be based on good faith negotiations between the PARTIES and, where the PARTIES are unable to agree, shall be based on the valuation conducted by the AUDIT FIRM, the costs of which will be equally shared by the PARTIES.

4.5 Should ANABIOS be required to pay royalties to a THIRD PARTY in order to SELL LICENSED PRODUCTS in order to not infringe such THIRD PARTY’s rights, the royalty rate due ZALICUS hereunder shall be reduced by 50% of the third-party’s royalty rate, but in no case shall the royalty due ZALICUS fall below 6%.

Such reports shall be due to ZALICUS on July 31 and January 31 of each year and shall include at least:

Simultaneously with the delivery of each report, ANABIOS shall pay to ZALICUS the amount, if any, due for the period of such report. If no payments are due, it shall be so reported.

Such payments shall be subject to applicable law and regulations. NET SALES from LICENSED PRODUCTS not denominated in U.S. dollars and the royalties payable thereon shall first be determined in the currency in which such LICENSED PRODUCTS were sold and shall then be converted into the equivalent number of U.S. dollars at the exchange rate published by The Wall Street Journal Eastern Edition as of each respective June 30 and December 31

6.3 In the event that any payment due hereunder to ZALICUS is not received when due, that payment shall accrue interest beginning on the tenth calendar day following the due date thereof, calculated at the annual rate of the sum of the prime interest rate quoted by The Wall Street Journal Eastern Edition on the date said payment is due plus two percent (2%) interest, the interest being compounded on the last day of each calendar quarter, provided, however, that in no event shall said annual interest rate exceed the maximum legal interest rate for corporations. Each such royalty payment when made shall be accompanied by all interest so accrued. Said interest and the payment and acceptance thereof shall not negate or waive the right of ZALICUS to seek any other remedy, legal or equitable, to which it may be entitled because of the delinquency of any payment. Nothing in this Article 5.3 shall be construed as a waiver by ZALICUS of timely payment to ZALICUS from ANABIOS.

6.4 During the term of this Agreement and for seven (7) years thereafter, ANABIOS shall keep complete, true and correct records of its, its AFFILIATES’ NET SALES from LICENSED PRODUCTS in sufficient detail to enable the royalties payable hereunder to be determined. ANABIOS shall permit ZALICUS or its representatives to periodically examine, upon ten (10) days prior written notice, but in no instance more than once per year, its books, ledgers, and records for the purpose of conducting an inspection and audit and to the extent necessary to verify any report required under this Agreement. Such books, ledgers, and records shall be available for inspection, audit, and copying by ZALICUS or ZALICUS’S representative or agent at ANABIOS’S principal place of business, during reasonable business hours. ZALICUS or ZALICUS’S representative or agent will be obliged to execute a reasonable confidentiality agreement prior to commencing any such inspection. ANABIOS will cooperate with ZALICUS or ZALICUS’S representatives in the performance of their inspection and audit, and ANABIOS agrees to cause its accountants and bookkeepers to cooperate fully in the inspection and audit. Such inspection and audit shall be at the sole expense of ZALICUS.

6.5 All amounts due and payable by ANABIOS under this Agreement shall be made without deductions for taxes, assessments, fees or other charges of any kind which may be imposed on ZALICUS by any government outside of the United States or any political subdivision of such government with respect to any amounts payable to ZALICUS pursuant to this Agreement. ZALICUS will cooperate with ANABIOS in assisting ANABIOS to obtain any credit to which ANABIOS may be entitled with respect to such payments.

ARTICLE 7

DUE DILIGENCE REQUIREMENTS

7.1 ANABIOS shall proceed diligently and in good faith with the development of LICENSED PRODUCTS and shall use its reasonable commercial efforts to bring LICENSED PRODUCTS to market through a thorough, vigorous and diligent commercialization program, which shall include but not be limited to the development, manufacture, marketing, promotion, distribution and sale of LICENSED PRODUCTS

7.2 At the sole discretion of ANABIOS or a SUBLICENSEE, the development of a LICENSED PRODUCT may be terminated at any time should any preclinical data or clinical trial fail to demonstrate adequate safety, efficacy or the potential for adequate commercial success. ZALICUS will be notified of any such decision 30 days prior to implementation of such decision. Said termination will comply with the terms described in Articles 12.2, 12.3, 12.4, 12.5 and 14.

7.3 In partial satisfaction of the obligations of Paragraph 7.1 above, ANABIOS, or its AFFILIATES or its SUBLICENSEE, shall exercise best efforts to achieve the following events within the time frame set forth below:

36 months from Effective Date

24 months from successful completion of Phase I

36 months from successful completion of Phase II

36 months from successful completion of Phase III

At each expected time point above, ANABIOS will report whether it has achieved the described event. If ANABIOS fails to achieve any of the development events set forth in this Article 6 within the timeframe described, ANABIOS and ZALICUS will first negotiate in good faith to determine how ANABIOS can either remedy such failure or achieve alternate mutually agreed upon development events within a reasonable timeframe. If the PARTIES are unable to mutually agree upon revised timelines or events above, the PARTIES will seek to resolve their dispute according to ARTICLE 15. If ANABIOS fails to make the required efforts, after they are so determined, does not remedy such failure within sixty (60) days of written notice by ZALICUS, or the parties are unable to resolve their dispute under ARTICLE 15, then ZALICUS may, by written notice to ANABIOS, terminate this License or convert it to non-exclusive, at ZALICUS’ sole discretion.

7.4 It is acknowledged by the parties that development can be delayed by unforeseen and unusual consequences neither caused by nor under the control of ANABIOS. Should such delays cause ANABIOS to fail to complete any development event within the allotted time, the periods allotted may be extended by mutual agreement, following sufficient documentation of such delays by ANABIOS.

ARTICLE 8

PATENT PROSECUTION

8.1 The PARTIES will form a patent prosecution steering committee (the “PATENT COMMITTEE”) comprised of one or more individuals from each PARTY who will confer at least semi-annually, and more frequently as dictated by the matters requiring prosecution attention, regarding patent prosecution strategy. Each PARTY will be responsible for compensation and expense reimbursement for its own committee member participants on the activities of the PATENT COMMITTEE. ANABIOS shall prosecute at its sole expense and maintain all Patent Rights using counsel of its choosing. The PATENT COMMITTEE will meet as frequently as needed (by telephone or in person at the PARTIES’ discretion), on the filing and prosecution of PATENT RIGHTS and the input of all committee members will be considered and reasonably incorporated into patent content and strategy. ANABIOS will be required to notify ZALICUS in advance and in writing of any action that would result in abridgement, abandonment, cancellation or abandonment of PATENT RIGHTS, at least 45 days in advance of such action. ZALICUS will then have 30 days to provide ANABIOS with a written response. Under no circumstances will any PATENT RIGHTS be abridged, abandoned, canceled or not pursued, without ZALICUS’ written approval, except in case ZALICUS fails to provide a written response within 30 days from receiving such written notification from ANABIOS.

8.2 ZALICUS will exercise reasonable effort in transferring all documents, information and other material relevant to ongoing filing and prosecution of PATENT RIGHTS so as to support any future effort on the part of ANABIOS in the filing and prosecution of Patent Rights.

ARTICLE 9

PATENT INFRINGEMENT & MARKING

9.1 Each Party agrees to notify the other promptly of any infringement of the licensed PATENT RIGHTS of which such PARTY becomes aware. ANABIOS shall have the first option to commence legal proceedings with respect to such infringement. Before ANABIOS commences legal proceedings with respect to any infringement of any such licensed PATENT RIGHTS (an “ACTION”), ANABIOS shall adopt all reasonable input of ZALICUS in making its decision whether or not to commence such an ACTION. If ANABIOS chooses not to pursue infringement of PATENT RIGHTS, the license will terminate or convert to non-exclusive at ZALICUS’S discretion. ANABIOS will not settle any ACTION without ZALICUS’S prior written approval.

9.2 If ANABIOS elects to commence an ACTION as described above, ANABIOS will use reasonable efforts and attorneys of its choice at its expense to enforce the licensed PATENT RIGHTS or, subject to ZALICUS’S concurrence, may obligate an AFFILIATE or SUBLICENSEE to carry out such ACTION on behalf of ANABIOS according to the terms set forth in this Article 9.

9.3 ZALICUS will have the option to participate, at its own cost, in any such Action, except that in the event that ZALICUS is requested by ANABIOS to join such Action, then ANABIOS shall pay all reasonable costs and expenses incurred by ZALICUS to so join.

9.4 Any monetary recovery or reimbursement (whether by settlement or judgment) in connection with an ACTION commenced by ANABIOS or its AFFILIATES or SUBLICENSEES shall first be applied to reimburse ANABIOS, its AFFILIATES or its SUBLICENSEES, if applicable, for all out-of-pocket expenses (including reasonable attorney’s fees) incurred in prosecuting such ACTION and for the expenses of ZALICUS borne by ANABIOS hereunder, and then to reimburse ZALICUS for royalties withheld. Any remaining balance shall be shared equally by ANABIOS and ZALICUS.

9.5 In the event that ANABIOS elects not to exercise its option to prosecute an infringement of the licensed PATENT RIGHTS pursuant to this Article 9, ZALICUS may do so at its own cost and expense, controlling such Action and retaining all recoveries therefrom.

9.6 The PARTIES shall promptly inform one another in writing of any written notice to either PARTY of alleged infringement or misappropriation, based on the making, using, or selling of a LICENSED PRODUCT, of a THIRD PARTY’s intellectual property rights of which it shall become aware. Neither PARTY shall acknowledge to a THIRD PARTY the validity of any such allegation. The PARTIES shall each keep the other advised of all material developments in the said proceedings and shall cooperate with the other in the conduct of such defense

9.7 In accordance with the laws of the United States relating to the marking of patented articles, subsequent to the issuance of any patent in the United States within the PATENT RIGHTS, ANABIOS agrees, in accordance with applicable laws and regulations, to mark and to require every AFFILIATES and SUBLICENSEE to mark every LICENSED PRODUCT covered by said patent.
