(a) Intellectual Property Not Licensed. Except as expressly provided herein or in an Exhibit, nothing in this Agreement shall be construed as a grant to either party of any ownership or other interest in any copyrights, patents, trademarks, know-how, inventions, trade secrets and registrations and applications for the registration thereof ("Intellectual Property") of the other created on or before or after the Effective Date. (b) Joint Inventions. Any and all inventions developed by a Party, shall be owned by such developing Party, except that patents and applications for which employees or officers of both Parties are inventors will be jointly owned. Any such jointly owned patent or patent application shall be filed, prosecuted and maintained with the equal cooperation and at the equal expense of both Parties by a 5 patent attorney or agent agreed upon by both parties.

BDSI agrees to discuss with BND and give due consideration to BND's views as to other appropriate and reasonable reductions of such rate at any time that BND believes that market conditions make it economically unreasonable to pay BDSI a Running Royalty at the rates above on any Licensed Product. 4.3 Term of Running Royalty Obligations. The Running Royalty obligations specified in Sections 4.2 above shall continue for the term of the last to expire of (i) the term of this Agreement and (ii) the Licensed Patent rights covering the Licensed Product. 4.4 Date and Place of Sale.

BND shall convert all non-U.S. dollar sales to U.S. dollars using the average exchange rates quoted in the Wall Street Journal for the final day of each month in the relevant period for which the Running Royalty is being paid. In the event payment of any Running Royalties is restricted or prohibited by the laws or regulations of a particular country, then to the extent of such a restriction and prohibition, Running Royalties shall be paid to BDSI in that country and in the currency of said country into an account to be designated by BDSI. 4.7 Third Party Consideration. In the case of a Commercial Sale other than in an arm's-length transaction exclusively for money, such as barter or counter-trade, the amount of such 6 Commercial Sale shall be calculated using the fair market value of such Licensed Product (if higher than the stated sales price) in the country of disposition. 4.8 Taxation of Payments. (a) Insofar as any payment that is due BDSI under this Agreement is subject to any tax, duty, levy, or other government imposition, BDSI agrees to bear any and all such taxes, duties, levies or impositions. BDSI hereby authorizes BND to withhold such taxes, duties, levies or impositions from the payments which are payable to BDSI in accordance with this Agreement if BND is required to do so under the laws of the United States or any country in the Territory where such taxes, duties, levies or impositions are payable. Whenever BND deducts such tax, duty, levy or imposition from any payments due BDSI, then BND shall furnish BDSI with a certificate showing the payment of thereof to the United States or any country in the Territory. (b) In the event the Running Royalty payments which are due to BDSI under this Agreement are subject to value added taxation by any government, then BDSI shall bear such value added tax in full and BND shall be reimbursed therefor. If appropriate, BDSI may add such value added taxes to its royalty accounts, provided such value added taxes are credited against BND's value added tax debt and BND is reimbursed in full with respect thereto. Notwithstanding anything herein to the contrary, BND shall have no liability for any value added tax directly or indirectly relating to the Running Royalties. (c) In the event any payment by BND to BDSI is subject to a withholding or other income tax in any country in the Territory, BND shall so advise BDSI promptly following BND becoming aware of the applicability of any such tax. BDSI shall have the right to contest with the appropriate governmental body any such proposed withholding and BND shall provide, at BDSI's expense, reasonable cooperation to BDSI in any such contest. BND shall provide BDSI with such receipts or other evidence of any tax withheld as is necessary for BDSI to claim any credit or deduction available to it in other jurisdictions. Payments to BDSI shall only be reduced for withholding taxes imposed by the jurisdiction out of which the payment is directly made to the BDSI. 4.9 Interest. All payments due hereunder from BND that are not paid to BDSI when due and payable as specified in this agreement shall bear interest at an annual rate equal to the prime rate ("Prime Rate") for U.S. dollar deposits in effect from time to time, as published daily in the Wall Street Journal plus 2%, compounded monthly from the date due until paid, or at such lower rate of interest as shall then be the maximum rate permitted by applicable law. 4.10 Right to Documentation.

At the request and expense of BDSI, BND, its Affiliates and Sublicensees shall permit an independent, certified public accountant appointed by BDSI acceptable to BND or its Affiliates, at reasonable times and upon reasonable notice, to examine those records and all other material documents relating to or relevant to Net Sales Received and Sublicensee income in the possession or control of BND, its Affiliates or Sublicensees, for a period of three (3) years after such Running Royalties have accrued, as may be necessary to: (i) determine the correctness of any report or payment made under this Agreement; or (ii) obtain information as to the Running Royalties payable for any calendar quarter in the case of BND's or its Affiliate's failure to report or pay pursuant to this Agreement. Said accountant shall not disclose to BDSI any information other than information relating to said reports, Running Royalties, and payments. Results of any such examination shall be made available to both Parties. BDSI shall bear the full cost of the performance of any such audit, unless such audit demonstrates underpayment of royalties by BND of more than ten percent (10%) from the amount of the original Running Royalty payment made by BND. In such event, BND shall bear the full cost of the performance of such audit. BDSI shall have no right to audit or seek payment of any Running Royalties for any Commercial Sale after the date which is three years from the date of such Commercial Sale. ARTICLE 6 - PATENT PROSECUTION; ENFORCEMENT; INFRINGEMENT 6.1 Patent Prosecution and Maintenance.

Each Party agrees to provide the other Party with a copy of any proposed abstracts, presentations, manuscripts, or any other disclosure which discloses clinical study results pursuant to this Agreement or confidential information received from the other Party at least one hundred twenty (120) days prior to their intended submission for publication and agrees not to submit or present such disclosure until the Party not seeking to disclose such information provides its prior written approval. Such written approval will not be unreasonably withheld unless such proposed disclosure could reasonably harm or impair a Party's intellectual property assets or may reasonably cause commercial harm to a Party. 6.3 Notification of Infringement. If either Party learns of an infringement or threatened infringement by a Third Party of any Licensed Patent granted hereunder within the Territory, such Party shall promptly notify the other Party and shall provide such other Party with available evidence of such infringement. Section 6.3 shall then be applicable. 6.4 Patent Enforcement. BDSI shall have the first right, but not the duty, to institute patent infringement actions against third parties based on any Licensed Patent under this Agreement. If BDSI does not institute an infringement proceeding against an offending Third Party within ninety (90) days after receipt of notice from BND, BND shall have the right, but not the duty, to institute such an action. 8 The costs and expenses of any such action (including fees of attorneys and other professionals) shall be borne by the Party instituting the action, or, if the Parties elect to cooperate in instituting and maintaining such action, such costs and expenses shall be borne by the Parties in such proportions as they may agree in writing. Each Party shall execute all necessary and proper documents and take such actions as shall be appropriate to allow the other Party to institute and prosecute such infringement actions. Any award paid by third parties as a result of such an infringement action (whether by way of settlement or otherwise) shall be paid to the Party who instituted and maintained such action, or, if both Parties instituted and maintained such action, such award shall be allocated among the Parties in proportion to their respective contributions to the costs and expenses incurred in such action. 6.5 Infringement Action by Third Parties.

BND shall have the right to defend such claim or suit at its own expense, and BDSI hereby agrees to assist and cooperate with BND, at BDSI's own expense, to the extent necessary in the defense of such claim or suit. During the pendency of such claim or suit, BND shall continue to make all payments due under this Agreement, but shall have a credit against Running Royalties otherwise payable hereunder for the full amount of all costs and expenses incurred by BND in defending against such claim or suit; provided, however, that in applying the credit against any Running Royalty payment, the amount of such payment shall not be reduced by more than 50% and any remaining credit shall be applied against subsequent Running Royalty payments . (b) If as a result of any judgment, award, decree or settlement resulting from a claim or action instituted by a Third Party, BND is required to pay a royalty or other amounts to such Third Party ("Third Party Royalty"), BND shall continue to pay Running Royalties in the country which is the subject of such action, but shall be entitled to a credit against such payments in an amount equal to the Third Party Royalty, but in no event shall such credit be more than the Running Royalties due hereunder in such country which is the subject of such action and any remaining credit shall be applied against subsequent Running Royalty payments. In addition, if BND is required to pay damages to such Third Party, and such damages are not otherwise reimbursed by BDSI, BND shall be entitled to a credit against Running Royalty payments in an amount equal to such damages, to the extent paid by BND to such Third Party, but in no event shall the total credit provided hereunder be more than such Running Royalties due hereunder for such Licensed Products in such country which is the subject of such action.

EXHIBIT B LICENSED TECHNOLOGY I. COCHLEATE TECHNOLOGY Origin of cochleates Over the years, biochemists and biophysicists have studied artificial membrane systems to understand their properties and potential applications. In studying this topic, Demetrios Papahadjopoulos and coworkers began investigating the interactions of divalent cations with negatively charged lipid bilayers. They reported that the addition of calcium ions to small phosphatidylserine vesicles induced their collapse into discs which fused into large sheets of lipid. In order to minimize their interaction with water, these lipid sheets rolled up into jellyroll-like structures, termed "cochleate" cylinders, after the Greek name for a snail with spiral shell. The Cochleate Advantage Cochleate delivery vehicles represent a new technology platform for oral and systemic delivery of clinically important drugs that possess poor bioavailability. For example, oral cochleates have been successfully used in animal models for the delivery of drugs that previously were only available given by injection. High stability: Cochleate delivery vehicles are stable phospholipids-divalent cation precipitates composed of simple, naturally occurring materials, for example, phosphatidylserine and calcium. They have a unique multilayered structure consisting of a large, continuous, solid, lipid bilayer sheet rolled up in a spiral, with no internal aqueous space. Cochleates can be stored in a cation-containing buffer, or lyophilized to a powder and stored at room temperature. Lyophilized cochleates can be placed in capsules and given orally, or reconstituted with liquid prior to in vitro use or in vivo administration. Lyophilization has no adverse effects on cochleate morphology or functions. Cochleate preparations have been shown to be stable for more than two years at 4(degree)C in a cation-containing buffer, and at least one year as a lyophilized powder at room temperature. Encochleation imparts increased stability to drugs, proteins and polynucleotides. Encapsulation: Cochleate delivery vehicles "wrap-up" or encapsulate the drug, rather than chemically bond with the included drug. Target delivery: Cochleates carry the encapsulated drug within the interior of the formulation and delivery the drug to the target cell. This results in low blood levels of free drug and high efficiency delivery to the target cell. Once at the target cell, cochleates can be envisioned as membrane fusion intermediates. When a cochleate comes into close approximation to a target membrane, a fusion event between the outer layer of the cochleate and the cell membrane occurs. This fusion results in the delivery of a small amount of the encochleated material into the cytoplasm of the target cell. The cochleate may slowly fuse or break free of the cell and be available for another fusion event, either with this or another cell. Cochleates may also be taken up by endocytosis, and fuse from within endocytic vesicles. Resistance to environmental attack: The unique structure of the cochleate provides protection from degradation for associated "encochleated" molecules. Traditionally, many drugs can be damaged from exposure to adverse environmental conditions such as sunlight, oxygen, water and temperature. Since the entire cochleate structure is a series of solid layers, components within the interior of the cochleate structure remain intact, even though the outer layers of the cochleate may be exposed to harsh environmental conditions or enzymes. Oral availability: The drug delivery technology is being developed to enable oral availability of a broad spectrum of compounds, such as those with poor water solubility, as well as polynucleotides, and protein and peptide biopharmaceuticals, which have been difficult to formulate and administer. Release characteristics: The cochleate technology offers the potential to be tailored to control the release of the drug depending on the desired application. Formulation of Cochleates BDSI scientists have investigated various aspects of the manufacturing process, including pH, agitation method and rate, type of cation, ratio of lipid to material, and other parameters, in order to optimize the formulation and manufacturing process for a given material. In one typical manufacturing process, the materials to be formulated (chemical drugs, proteins, peptides, DNA, antigens, nutrients) are added to a suspension of liposomes comprised mainly of negatively charged lipids. The addition of divalent metal ions such as calcium, (although other multivalent cations can be used) induces the collapse and fusion of the liposomes into large sheets composed of lipid bilayers, which spontaneously roll up or stack into cochleates. If desired, the cochleates can be purified to remove unencochleated material, and then resuspended in a buffer containing divalent metal ions. Various processes have been developed by BDSI scientists to prepare cochleate formulations of a wide variety of drugs, peptides and proteins, with molecular weights ranging from 1 to greater than 200KD, and oligonucleotides or DNA of 20 to greater than 10,000 base pairs. The percentage of encochleation of material ranges from 40-95%, depending on the material and the manufacturing conditions. Biocompatibility of Cochleate Vehicles The fundamental components of the cochleate delivery vehicle are phosphatidylserine (PS) and calcium. Phosphatidylserine is a natural component of all biologic membranes, and is most concentrated in the brain. Clinical studies by other investigators, (more than 30 have been published), to evaluate the potential of phosphatidylserine as a nutrient supplement indicate that PS is very safe and may play a role in the support of mental functions in the aging brain. Indeed, phosphatidylserine isolated from soy beans is sold in health food stores as a nutritional supplement. In mice, BDSI has evaluated the in vivo safety of multiple administrations of cochleates by various routes, including intravenous, intraperitoneal, intranasal and oral. Multiple administrations of cochleate formulations to the same animal do not result in either the development of an immune response to the cochleate matrix, or to any side effects relating to the cochleate vehicle. Mechanism of Delivery The interaction of calcium with negatively charged lipids has been extensively studied. Many naturally occurring membrane fusion events involve the interaction of calcium with negatively charged phospholipids (generally phosphatidylserine and phosphatidylglycerol). Calcium induced perturbations of membranes containing negatively charged lipids, and the subsequent membrane fusion events, are important mechanisms in many natural membrane fusion processes. Hence, cochleates can be envisioned as membrane fusion intermediates. During the past several years substantial research by BDSI scientists has demonstrated that cochleate formulations are simple, safe and highly efficacious mediators of the in vivo delivery of proteins, peptides and polynucleotides for the induction of antigen specific immune responses following oral, intranasal and intramuscular administration. Significantly, the ability of cochleates to mediate the induction of antigen specific, CD8+ cytotoxic lymphocytes, as well as the efficient induction of immune responses to plasmid encoded antigens, supports the hypothesis that cochleates facilitate the cytoplasmic delivery of cochleate associated bioactive molecules. The observations indicate that, as the calcium rich, highly ordered membrane of a cochleate first comes into close approximation to a natural membrane, a perturbation and reordering of the cell membrane is induced. This results in a fusion event between the outer layer of the cochleate and the cell membrane. This fusion also results in the delivery of a small amount of the encochleated material into the cytoplasm of the target cell. The cochleate may slowly fuse or break free of the cell and be available for another fusion event, either with this or another cell. Cochleates may also be taken up by endocytosis, and fuse from within endocytic vesicles. Uptake of Cochleates by Macrophage An important observation relative to the interaction of cochleates with cells is their uptake by macrophage. For example, in vivo, fluorescent cochleates are accumulated by macrophage. Macrophages are on the first line of defense against microbial infections. Many human pathogens cause diseases because they have developed the capacity to survive within macrophage. Examples include viruses such as HIV, bacteria such as staphylococcus and Mycobacterium tuberculosis, fungi such as Candida and parasites such as Leishmania. Cochleate Mediated Oral Delivery of Drugs Cochleate formulation technology is particularly applicable to macromolecules as well as small molecule drugs that are hydrophobic, positively, or negatively charged, and possess poor oral bioavailability. Proof-of-principle studies for cochleate mediated oral delivery of macromolecules as well as small molecule drugs is being carried out in appropriate animal models with a well established, clinically important drug which currently can only be effectively delivered by injection, amphotericin B, a potent antifungal agent. II. PROTEOLIPOSOME TECHNOLOGY Proteoliposome Technology (PLT), relates to novel liposome compositions and methods for their preparation. Utilization of PLT provides an efficient reconstitution of membrane proteins into large (0.1 to 2 micron diameter) phospholipid vesicles with a large, internal aqueous space. The method has been exemplified with the use of glycoproteins of influenza (A/PR8/34) and Sendai (parainfluenza type I) viruses. The method comprises (A) extracting out the desired membrane protein from a source biological material with an extraction buffer comprising a detergent; (B) mixing the extract with a phospholipid solution and deriving a cochleate intermediate; and (C) forming large phospholipid vesicles with integrated membrane protein in a biologically active state. PLT has been used to produce liposome structures with improved delivery capabilities for drug delivery and gene therapy as well as enhanced immune responses. In addition, BDSI PLT can be used to formulate and stabilize biologically important but structurally fragile hydrophobic proteins. The PLT is protected by US Patent Nos. 4,663,161 and 4,871,488. III. Geodate Technology Geodate technology generally relates to a novel delivery vehicle that encapsulates agents in a stable emulsion, slurry, or powder. Geodate technology is particularly attractive for use with hydrophobic agents, as it can incorporate them at a high yield. It also is particularly attractive for delivery of fragile or unstable agents as the "geodes" remain intact and protect the fragile core molecules, such as beta-carotene, under environmental conditions that normally will result in destruction or inactivation of the molecules. It has been discovered by BDSI scientists that a monolayer of lipid can form about a hydrophobic core, and that this monolayer can further be encrusted in a lipid/cation matrix, further protecting the hydrophobic core. The resulting "geode" is highly stable and protects of the core from degradation or inactivation, even at elevated pressures and temperatures, such as those encountered in food processing technology.
