(a) the amount of such underpayment; and

(b) if such underpayment exceeds [***] percent [***] of the total Earned Royalties owed for the fiscal year then being reviewed, the reasonably necessary fees and expenses of such independent public accountant performing the audit. Otherwise, EMORY's accountant's fees and expenses shall be borne solely by EMORY. Any overpayment of Earned Royalties shall be fully creditable against future Earned Royalties payable in any subsequent royalty period.

4.3 Confidentiality of Records. All information subject to review under this Article 4 shall be confidential. Except where disclosure is required by law, EMORY and its accountant shall retain all such information in confidence.

If, at any time, legal restrictions prevent the prompt remittance of part of or all Earned Royalties or Upfront Sublicense Fees with respect to any country in the Licensed Territory where Licensed Products are Sold, CBT, its Affiliates or sublicensees shall have the right and option to make such payments by depositing the amount thereof in local currency to EMORY's account in a bank or depository in such country.

5.3 Interest. Earned Royalties, Upfront Sublicense Fees, Milestone Payments and other payments required to be paid by CBT pursuant to this Agreement shall, if overdue, bear interest at the lesser of the maximum applicable legal rate of interest on overdue commercial accounts or a per annum rate of [***] percent [***] until paid. The payment of such interest shall not foreclose EMORY from exercising any other rights it may have because any payment is overdue.

For purposes of this Agreement, “best efforts” shall mean that CBT shall use reasonable efforts consistent with those used by comparable biotechnology companies in the United States in research and development projects for diagnostic methods or kits and therapeutic methods or compositions deemed to have commercial value comparable to the Licensed Products.

6.3 Effect of Failure. If CBT fails to use its best efforts pursuant to Section 6.1, EMORY may, upon at least sixty (60) days' prior written notice of such failure to CBT, grant Third Parties identical or lesser rights in the Licensed Patents and Licensed Technology as granted to CBT hereunder for Licensed Products, unless within such sixty (60) day period, CBT cures such failure. Any disputes as to failure by CBT to meet its diligence obligations in accordance with this Article 6 shall be resolved pursuant to Section 14.1.

6.4 Progress Reports. CBT shall, no less frequently than once every twelve (12) months until a Licensed Product has achieved Regulatory Approval or Authorization, provide EMORY with a written report detailing CBT’s, its Affiliates’s or sublicensees’s activities related to developing Licensed Products and pursuing Regulatory Approval or Authorization of Licensed Products. Such reports shall also incorporate sufficient detail regarding the amount and use of research and development funds to enable EMORY to verify CBT's compliance with Section 6.1 herein.

6.5 Development in the United States and Major Markets. No later than CBT's filing of an NDA or its equivalent in a Major Market for a Licensed Product in the United States or a Major Market, CBT shall directly, or in collaboration with its Affiliates or sublicensees, use its best efforts:

(a) to obtain Regulatory Approval or Authorization for such Licensed Product in such other countries of the Licensed Territory as CBT, CBT’s Affiliates or sublicensees deem appropriate; and

(b) upon Regulatory Approval or Authorization of such Licensed Product in a particular country, proceed with due diligence to market such Licensed Product in such country.

6.6 Development of Indications. CBT and EMORY acknowledge that the compositions and methods claimed in the Licensed Patents may be useful for a number of indications. CBT shall, in accordance with its diligence obligations, attempt to develop the Licensed Patents and Licensed Technology for such other indications if scientific evidence provided by EMORY, and accepted as significant evidence in the scientific community, supports that the Licensed Patents and Licensed Technology are useful for such other indications.

If EMORY reasonably believes that CBT is not using diligence to attempt to develop an indication for which the diligence obligation has accrued under the above paragraph, then EMORY may, commencing on the fifth anniversary date of this Agreement, request in writing that CBT enter into negotiations with prospective sublicensees which EMORY believes are interested in developing such indication which CBT, or its Affiliate or sublicensee, is not then developing. Within thirty (30) days of receipt of such written request, CBT shall either: (i) commence and diligently pursue good faith negotiations with such prospective sublicensee, (ii) provide EMORY with a reasonable development plan, including milestones, for such indication, or (iii) release any rights granted to CBT by EMORY under this Agreement as may be required to enable EMORY to license Third Parties the rights required to develop such indication.

ARTICLE 7. PATENT PROSECUTION

7.1 Licensed Patents Assigned to EMORY.

7.1.1 EMORY shall be primarily responsible for all patent prosecution activities pertaining to Licensed Patents assigned solely to EMORY. EMORY shall provide CBT with copies of all filings and correspondence pertaining to such patent prosecution activities, in a timely manner, so as to give CBT an opportunity to comment thereon. EMORY shall use good faith efforts to accommodate all such comments if timely received. EMORY shall pursue prosecution of such Licensed Patents in at least the following countries: United States, EPO countries, Canada, and Australia.

7.1.2 For all out-of-pocket costs after the Effective Date for on-going patent prosecution activities on Licensed Patents (the “Future Patent Costs”), EMORY shall submit such costs to CBT for approval prior to expenditure. CBT shall reimburse EMORY, not later than thirty (30) days after receiving an invoice therefore from EMORY, all such approved Future Patent Costs. If CBT fails to promptly reimburse EMORY within sixty (60) days after receipt of invoice from EMORY for approved Future Patent Costs, EMORY shall provide written notice to CBT of such failure and if CBT does not pay the undisputed amount of such invoice within thirty (30) days after such notice, then the patent application or issued patent associated with such Future Patent Costs shall not be considered a Licensed Patent and EMORY shall be free, at its election, to abandon or maintain the prosecution of such patent application or issued patent or grant rights to such patent application or issued patent to Third Parties.

7.2 Licensed Patents Jointly Assigned to CBT and EMORY.

7.2.1 EMORY shall be primarily responsible for all patent prosecution activities pertaining to any Licensed Patents arising out of the Research Agreement pursuant to Section 3.6 and jointly assigned to EMORY and CBT. EMORY, with the agreement of CBT, shall select patent counsel to prosecute all such Licensed Patents and shall provide CBT with copies of all filings and correspondence pertaining to such patent prosecution activities, in a timely manner, so as to give CBT an opportunity to comment thereon. EMORY shall advise such patent counsel in writing that for purposes of such patent activities, such counsel represents both EMORY and CBT. EMORY shall pursue prosecution of such Licensed Patents in at least the following countries: [***].

7.2.2 For all out-of-pocket costs for on-going patent prosecution activities pertaining to any Licensed Patents arising out of the Research Agreement pursuant to Section 3.6 and jointly assigned to EMORY and CBT, EMORY shall submit such costs to CBT for approval prior to expenditure. CBT shall reimburse EMORY, not later than thirty (30) days after receiving an invoice therefor from EMORY, all such approved patent costs. If CBT fails to promptly reimburse EMORY within sixty (60) days after receipt of invoice from EMORY for approved patent costs, EMORY shall provide written notice to CBT of such failure and if CBT does not pay the undisputed amount of such invoice within thirty (30) days after such notice, then CBT shall, upon EMORY's request, assign its interests in such patent application or issued patent to EMORY. After such assignment, such patent application or issued patent shall no longer be considered a Licensed Patent and EMORY shall be free, at its election, to abandon or maintain the prosecution of such patent application or issued patent or grant rights to such patent application or issued patent to Third Parties.

ARTICLE 8. INFRINGEMENT

8.1 Enforcement by CBT. If either CBT or EMORY becomes aware of a product made, used or sold in the Licensed Territory, which it believes infringes a Valid Claim, the Party obtaining such knowledge shall promptly advise the other Party of all relevant facts and circumstances pertaining to the potential infringement. CBT shall have the first right to enforce any patent rights against such infringement, at its own expense. EMORY shall cooperate with CBT in such effort, at CBT's expense, including being joined as a Party to such action, if necessary. Any damages or costs recovered in connection with any action filed by CBT hereunder which exceed CBT's out-of-pocket costs and expenses of litigation, shall be deemed to be Net Sales from Sales of Licensed Products in the fiscal quarter in which received by CBT, and Earned Royalties shall be payable by CBT to EMORY thereon in accordance with the terms of this Agreement.

8.2 Backup Enforcement Right by EMORY. If CBT fails, within one hundred twenty (120) days after receiving notice from EMORY of a potential infringement, or providing EMORY with notice of such infringement, to either (a) terminate such infringement or (b) institute an action to prevent continuation thereof and, thereafter to prosecute such action diligently, or if CBT notifies EMORY that it does not plan to terminate the infringement or institute such action, then EMORY shall have the right to do so at its own expense; provided however, that EMORY first consults with CBT and gives due consideration to CBT’s reasons for not instituting actions to terminate or otherwise prevent continuation of such infringement. If EMORY decides to pursue such infringement, CBT shall cooperate with EMORY in such effort including being joined as a Party to such action if necessary. EMORY shall be entitled to retain all damages or costs awarded to EMORY in such action.

ARTICLE 9. EXCLUSION OF WARRANTIES

CBT possesses the necessary expertise and skill in the technical areas pertaining to the Licensed Patents, Licensed Products and Licensed Technology to make, and has made, its own evaluation of the capabilities, safety, utility and commercial application of the Licensed Patents, Licensed Products and Licensed Technology. ACCORDINGLY, EMORY DOES NOT MAKE ANY REPRESENTATION OR WARRANTY OF ANY KIND WITH RESPECT TO THE LICENSED PATENTS, LICENSED TECHNOLOGY OR LICENSED PRODUCTS AND EXPRESSLY DISCLAIMS ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE AND ANY OTHER IMPLIED WARRANTIES WITH RESPECT TO THE CAPABILITIES, SAFETY, UTILITY, OR COMMERCIAL APPLICATION OF THE LICENSED PATENTS, LICENSED TECHNOLOGY OR LICENSED PRODUCTS.

CBT’s obligations under this Article 10 shall survive the expiration or termination of this Agreement for any reason.

10.2.2 To be eligible to be indemnified hereunder, the Indemnitees shall provide CBT with prompt notice of the claim giving rise to the indemnification obligation pursuant to this Article 10 and the exclusive ability to defend (with the reasonable cooperation of the Indemnitees) or settle any such claim; provided however, that CBT shall not enter into any settlement for damages other than monetary damages without the Indemnitees’s written consent, such consent not to be unreasonably withheld or delayed. The Indemnitees shall have the right to participate, at their own expense and with counsel of their choice, in the defense of any claim or suit that has been assumed by CBT.

10.3 Insurance. Without limiting CBT's indemnity obligations under the preceding paragraph, CBT shall, prior to any clinical trial or Sale of any Licensed Product, cause to be in force, an “occurrence based type” liability insurance policy which:

(a) insures Indemnitees for all claims, damages, and actions mentioned in Section 10.2.1 of this Agreement;

Any hearings shall be held in Atlanta, Georgia.

14.2 Export Controls. CBT acknowledges that EMORY is subject to United States laws and regulations controlling the export of technical data, biological materials, chemical compositions and other commodities and that EMORY's obligations under this Agreement are contingent upon compliance with applicable United States export laws and regulations. The transfer of technical data, biological materials, chemical compositions and commodities may require a license from the cognizant agency of the United States government or written assurances by CBT that CBT shall not export data or commodities to certain foreign countries without the prior approval of certain United States agencies. EMORY neither represents that an export license shall not be required nor that, if required, such export license shall issue.

14.10 Survival. Articles 10 and 11 shall survive termination of this Agreement for any reason. Sections 12.6 and 12.7 shall survive termination pursuant to Section 12.2 or Section 12.4(b), as applicable.

14.11 Severability. All rights and restrictions contained herein may be exercised and shall be applicable and binding only to the extent that they do not violate any applicable laws and are intended to be limited to the extent necessary so that they will not render this Agreement illegal, invalid or unenforceable. If any provision or portion of any provision of this Agreement, not essential to the commercial purpose of this Agreement, shall be held to be illegal, invalid or unenforceable by a court of competent jurisdiction, it is the intention of the parties that the remaining provisions or portions thereof shall constitute their agreement with respect to the subject matter hereof, and all such remaining provisions, or portions thereof, shall remain in full force and effect. To the extent legally permissible, any illegal, invalid or unenforceable provision of this Agreement shall be replaced by a valid provision which shall implement the commercial purpose of the illegal, invalid, or unenforceable provision. In the event that any provision essential to the commercial purpose of this Agreement is held to be illegal, invalid or unenforceable and cannot be replaced by a valid provision which will implement the commercial purpose of this Agreement, the Party who is the beneficiary of such illegal, invalid or unenforceable provision has the right to terminate this Agreement upon written notice, effective upon receipt, to the other Party.

14.12 Force Majeure. Any delays in, or failure of performance of any Party to this Agreement, shall not constitute a default hereunder, or give rise to any claim for damages, if and to the extent caused by occurrences beyond the control of the Party affected, including, but not limited to, acts of God, strikes or other concerted acts of workmen, civil disturbances, fires, floods, explosions, riots, war, rebellion, sabotage, acts of governmental authority or failure of governmental authority to issue licenses or approvals which may be required.

APPENDIX “A”

PROJECT

To determine the longest sustained plasma concentration of noscapine that is effective in tumor treatment without causing toxicity

Hypothesis: Given the short half-life of noscapine in circulation (~3 hours after oral intake), a time period much shorter than the cell cycle arrest (~12 to 20 hours), we predict increased time of noscapine circulation might be more effective for tumor treatment.

Significance: This preclinical knowledge will be necessary to design slow-release pills that can achieve the maximal efficacy for tumor treatment without severe toxicity for clinical trials in humans.

The Plan: To make this study more cost effective, we arrived at a conclusion that it should be done in two to three phases. At this time, only Phase A of the study (described below) will be performed.

Phase A. We will test the optimal amount of time of noscapine exposure that can most efficiently kill cancer cells without affecting the normal human cells.

(Budget: A total cost of ~$75,OOO)

The P.I. Time (no cost requested)

Experienced postdoc time (salary plus fringe) $40,000.

Supplies (‘~35,000): Disposable tissue culture plastics, gloves, disposable pipettes and pipette-tips. (~$13,000). Media components, C02, liquid nitrogen, confocal microscopy time. Fetal Calf serum, control and experimental drugs, vinca alkaloid, Taxol, noscapine hydrochloride, buffers, DNA gel and protein gel reagents, Cost for normal primary human foreskin fibroblasts (from our cell bank), fluorescent DNA dyes, FACS time, HPLC or radioactive methods of cellular noscapine uptake, clearance, kits for apoptotic assays etc. (~$22,000).

Background:

Mutations that inactivate mitotic checkpoints have recently been defined in several types of human cancers (Cahill et al., 1998; Jin et al., 1998; Yamaguchi et al., 1999; Zhou et al., 1999). In fact, a mitotic stress checkpoint gene Chfr (checkpoint with FHA and ring finger domain) was found to become inactivated in cells owing to lack of expression or by mutation in half of human cancers examined (Scolnick and Halazonetis, 2000). Furthermore, in addition to its involvement in the G1-S checkpoint, the presence of intact tumor suppressor gene p53 is also required for the spindle checkpoint (Cross et al., 1995). Therefore, the loss of mitotic checkpoints in tumor cells might, in fact, be a very common occurrence associated with cancer. Cells that lack mitotic checkpoints are highly sensitive to mitotic stress caused by microtubule targeting agents. It is thus becoming appreciated that such a checkpoint loss might contribute positively toward chemotherapeutic outcome of some cancers (Cahill, et al., 1998; Jin et al., 1998; Yamaguchi et al., 1999; Zhou et al; 1999).

Page 13 of 18

The first indication for the existence of the mitotic checkpoints came fiom the observation that certain microtubule depolymerizing agents, such as colchicine and vinca alkaloids, as well as agents that form stable bundles of microtubules such as taxanes, arrested most dividing cells in mitosis. In addition to halting the mitotic growth of dividing cells, these agents also block intracellular transport of components over long distances that requires intact microtubule tracks (see for e.g., Theiss and Meller, 2000). As a result, post-mitotic cells such as neurons, which rely upon intact cellular microtubules for the maintainance of presynaptic termini, are adversely affected by these agents (Johnson, 1984, Lyss et al., 1989). Nevertheless, vinca alkaloids and taxanes quickly found their way into the clinic despite the predicted side effects of halting natural cell division (myelosuppression, neuropathies, alopecia, and colitis) and intracellular transport (peripheral neuropathies) (Lobert and Correia, 1992).

Based upon structural similarities among a class of microtubule depolymerizing agents, we identified a small, natural alkaloid, noscapine, that binds stoichiometrically to tubulin and substantially alters its autofluorescence and CD spectra, but does not affect the net level of the cellular microtubule polymers (Ye et al., 1998). By recording the dynamic behavior of individual microtubules in live cultured mammalian cells, we now know that noscapine treatment reduces the transition frequencies between growth and shrinkage phases without causing a net change in the steady state polymer levels. This subtle alteration of microtubule dynamics was sufficient to engage the mitotic checkpoint, which delays anaphase onset in many types of cultured cells, including primary glia. An NCI screen of 60 human tumor cells revealed that noscapine was effectively toxic to many cancer types, including glioblastomas. Our preliminary data showed that the cytotoxicity of noscapine on a rat C6 glioma cells results from a failure to arrest mitosis leading to increased ploidy, followed by cell death. However, normal glial cells arrest in mitosis. After the removal of the drug, by washing cells with fresh culture medium or by allowing enough time for the metabolic inactivation of noscapine, the normal glial cells resumed the normal cell cycle.

Noscapine is a small, water soluble alkaloid from opium and is widely used as an antitussive (cough suppressant) agent in Europe and Asia with very little evidence of any toxicity (Chopra et al., 1930; reviewed in Joshi and Zhou, 2000, Ke et al., 2000). The bioavailability, pharmacokinetics, half-life, and the metabolism of noscapine are relatively well studied both in animals and in humans (Dahlstrom et al., 1982, Karlsson 1990). After oral ingestion, the serum concentration peaks in 2-4 hours and is then cleared mostly through urine, primarily as two metabolites (Dahlstrom et al., 1982). These metabolites do not affect mitosis (Ye and Joshi, 2000, unpublished).

The use of antineoplastic agents that interact with microtubules represent one therapeutic approach to treat tumors that exhibit uncontrolled cell division. The mechanism of action of antimitotic agents has been the subject of intensive investigation. These agents disrupt the dynamics of microtubules, which are essential for mitotic spindle activity. Microtubule-targeting drugs currently in use either promote excessive stability of microtubules, such as the taxane family, or induce depolymerization of microtubules like the vinca alkaloids (Jordan and Wilson, 1999). Our prior results suggest that the most prominent effect of noscapine is on microtubule dynamics. Noscapine exposure was found to significantly enhance the percentage of time microtubules spend idle, or in a paused state, in living cells at micromolar doses (Landen et al., 2002).

Page 14 of 18

Because checkpoint mechanisms in tumor cells are frequently faulty (Lengauer et al., 1998, Cahill et al, 1999), cancer cells may be more susceptible than normal cells to noscapine due to a lack of intact checkpoints to arrest cell cycle by the compromised microtubule dynamics caused by noscapine. Thus, cancer cells may not arrest when exposed to noscapine and undergo repeated mitoses and DNA duplication events without physically dividing (cytokinesis) leading to polyploidy and cell death.

Summary of the published preclinical pharmacology profile of noscapine in rodents and humans

The absorption, distribution and elimination rates and routes as well as the metabolic fate of noscapine have been studied extensively both in animal models and in humans. Highest concentrations of noscapine were found in the liver, kidney, urinary bladder, fat and subcutaneous tissue five minutes after administration by intra venous rout (i.v.). The overall noscapine levels in the blood, connective tissue and lungs remained fairly constant. Noscapine from subcutaneous tissue diffused rapidly from 20- 60 minutes after administration. The peak concentration of noscapine after i.v. injection, began clearance from circulation rapidly (with the half-life of >5 minutes see below) most of the dose is found in the large bowel. The majority (85-90%) of noscapine is found to exit the system within 24 hours without any toxic effects. The appearance of noscapine in thirteen systems is summarized below:

The absorption of noscapine from the gastrointestinal tract (GI tract) is rapid and complete. From 5 to 60 minutes after i.v., moderate activity was found in the salivary glands. Noscapine is found to reach the stomach in fifteen minutes, to the small intestine in 60 minutes, and the large intestine in 3 hours. After 6 hours, noscpaine was found in the oral mucosa. A well-marked but temporary inhibition of peristalisis was noted along with a paralyzing effect on the smooth intestine muscle probably due to depressant action on involuntary muscle fibers of the intestine wall (Chopra et. al. 1930). Peptic digestion and pancreatic enzymes are not affected much by noscapine.

Conclusion:

Given the short half life of noscapine in circulation, we predict increased time of noscapine circulation might be more effective for tumor treatment without much toxicity to normal cells.
