2.6. Y3H Target Identification and Disposition.

2.6.1 Y3H Target Identification. GPC and ALTANA shall use Commercially Reasonable Efforts in the Field to identify and validate Y3H Targets in the performance of the Collaboration, managed by the Collaboration Committee, according to the Research Plan in Exhibit B. The Collaboration Committee shall promptly notify the Joint Steering Committee of any such Y3H Target identified and submit the Designation Criteria of such Y3H Target and information regarding such place at which the agreed validation experiments have to be carried out as agreed by the Collaboration Committee. The Joint Steering Committee shall prioritize, coordinate and determine the extent of the further work to be performed as agreed by the Collaboration Committee for such Y3H Targets identified. Upon completion of such validation by ALTANA or GPC (as determined by the Collaboration Committee), the Collaboration Committee shall promptly notify the Joint Steering Committee of the results of such experiments pursuant to Section 2.6.2.

2.6.2 Recommendation by Collaboration Committee and Joint Steering Committee. The Collaboration Committee shall, further to Section 2.6.1, without undue delay following disclosure of the validation results of any Y3H Target pursuant to Section 2.6.1, convene in person, by telephone or by video conference in order to evaluate each Y3H Target so validated and shall, if it considers the Designation Criteria to be met, recommend to the Joint Steering Committee that such Y3H Target be designated as a Catalogue Y3H Target. Upon receipt of such recommendation from the Collaboration Committee, the Joint Steering Committee itself shall review the results and, if it also considers the Designation Criteria to be met, recommend to ALTANA to designate such Y3H Target as a Catalogue Y3H Target, all without undue delay. Following such recommendation, ALTANA shall determine pursuant to Section 2.6.4 and 2.6.5 hereof, whether such Y3H Target shall be designated a Catalogue Y3H Target or a Reverted Y3H Target.

2.6.3 Determination by ALTANA. Following the recommendation by the Joint Steering Committee pursuant to Section 2.6.2, ALTANA shall, through its internal committee, further evaluate each Y3H Target to determine if such Y3H Target meets the Designation Criteria.

2.6.4 Catalogue Y3H Target. If ALTANA determines, within ninety (90) days of the date of the Joint Steering Committee meeting at which the recommendation to ALTANA with respect to a Y3H Target pursuant to Section 2.6.2 was made, that such Y3H Target meets the Designation Criteria, then ALTANA shall notify GPC in writing (the “Catalogue Y3H Target Notice”) and such Y3H Target shall constitute a “Catalogue Y3H Target”. ALTANA shall make the Research Milestone payment as specified in Section 6.1.4(c) within thirty (30) days from the Catalogue Y3H Target Notice. ALTANA shall have exclusive rights to any Licensed Patents claiming such Catalogue Y3H Target pursuant to Section 3.1.1. Within thirty (30) days after any

Y3H Target becomes a Catalogue Y3H Target, GPC shall provide ALTANA with access to all Information under GPC Control for such Catalogue Y3H Target.

2.6.5 Reverted Y3H Target. If ALTANA determines that a Y3H Target does not meet the Designation Criteria and so notifies GPC in writing, or if ALTANA fails to notify GPC in writing with a Catalogue Y3H Target Notice of its determination within ninety (90) days of the Joint Steering Committee’s recommendation to ALTANA with respect to a Y3H Target pursuant to Section 2.6.2, or fails to make the payment required in Section 6.1.4(c) hereof and such failure has not been cured within twenty (20) days after receipt of notice thereof from GPC, then such Y3H Target shall be designated a “Reverted Y3H Target,” and GPC shall have exclusive rights to Collaboration Patents claiming such Reverted Y3H Target pursuant to Section 3.3.2.

2.6.6 ALTANA Accepted Y3H Target. In the event a Y3H Target is designated by ALTANA as a Catalogue Y3H Target pursuant to Section 2.6.4 hereof, ALTANA shall diligently undertake to additionally validate a Catalogue Y3H Target as soon as reasonably possible (taking into account ALTANA’s resources) and shall have the right to elect a Catalogue Y3H Target to become an Accepted Y3H Target. Such election must be made within the twenty-one (21) month period beginning on the date ALTANA designates a Y3H Target as a Catalogue Y3H Target (the “Evaluation Period”). In the event that, despite ALTANA’s Commercially Reasonable Efforts, ALTANA is unable to sufficiently validate a Catalogue Y3H Target within the Evaluation Period, the Parties shall negotiate in good faith an extension of the Evaluation Period, if any. In the event ALTANA desires to elect to have a Catalogue Y3H Target designated as an Accepted Y3H Target pursuant to this Section, ALTANA shall notify GPC within the Evaluation Period (as it may be extended pursuant to the preceding sentence) in writing of such election (the “Accepted Y3H Target Notice”) and such Y3H Target shall constitute an “Accepted Y3H Target”. ALTANA shall effect the payment required in Section 6.1.4(d) hereof within thirty (30) days from the Accepted Y3H Target Notice.

2.6.7 GPC Elected Y3H Target. In the event ALTANA does not elect a Catalogue Y3H Target to become a ALTANA Accepted Y3H Target and make the payment required by Section 6.1.4(c) pursuant to Section 2.6.6 hereof, or fails to notify GPC in writing with an Accepted Y3H Target Notice of the election of an Accepted Y3H Target with respect to a Catalogue Y3H Target pursuant to Section 2.6.6, then such Catalogue Y3H Target shall automatically be designated a “GPC Elected Y3H Target,” and ALTANA’s license to such Catalogue Y3H Target under Sections 3.1.1 and 3.1.2 shall automatically terminate, and GPC shall have exclusive rights to ALTANA Intellectual Property and Collaboration Patents claiming such GPC Elected Y3H Target pursuant to Section 3.3.3. Within thirty (30) days after any Catalogue Y3H Target becomes a GPC Elected Y3H Target, ALTANA shall provide GPC with access to Information under ALTANA Control for such GPC Elected Y3H Target.

2.7. Option on Third Party Technologies. At any time, and from time to time, during the Establishment Term, ALTANA may exercise an option (the “Option”) to enter into negotiations to obtain a non-exclusive license as an amendment under this Agreement only for use with or in 3-Hybrid Technology, to any technology in-licensed or acquired by GPC from any Third Party, wherein such technology is used by GPC in 3-Hybrid Technology(the “In-Licensed 3-Hybrid Technology”). GPC shall, upon execution of such in-licensing or acquisition agreement with a Third Party, inform the Joint Steering Committee accordingly and ALTANA may exercise the Option by providing written notice (the “Option Notice”) to GPC. If GPC is

not, at the time of receipt of the Option Notice, restricted from granting a non-exclusive license to such In-Licensed 3-Hybrid Technology, GPC shall negotiate in good faith with ALTANA, for a period of not less than 90 days, the terms of a non-exclusive license to the In-Licensed 3-Hybrid Technology. If, at the end of such 90-day period, ALTANA and GPC are, despite good faith efforts, unable to agree on the terms of such a non-exclusive license, then GPC shall be under no further obligation to grant to ALTANA a license to the In-Licensed 3-Hybrid Technology. Notwithstanding this and for the avoidance of doubt, an In-Licensed 3-Hybrid Technology being an improvement (i.e. vector systems, new readout systems) that replaces or modifies a part of or is an incorporation within an existing 3-Hybrid Technology used by the Parties shall be available for non-exclusive license (where GPC is not restricted in such license grant as above) as an Option to ALTANA against reasonable participation by ALTANA in the costs incurred with GPC regarding such In-Licensed 3-Hybrid Technology. In case such In-Licensed 3-Hybrid technology is a minor improvement, such non-exclusive license shall be as an Option to Altana on terms equivalent to the cost incurred by GPC to grant such license.

	Royalty Rate
Net Sales	Products Marketed for ***	Products Marketed for Indications ***

Less than or equal to $100 million	***	***

Greater than $100 million but less than or equal to $250 million	***	***

Greater than $250 million but less than or equal to $500 million	***	***

Greater than $500 million but less than or equal to $1,000 million	***	***

Greater than $1,000 million	***	***

Royalties with respect to each Product shall be paid to GPC on a country-by-country basis for the longer of (a) 10 years from First Commercial Sale of such Product in such country; (b) until there no longer exists a Valid Claim covering the therapeutic agent or active ingredient within such Product (without regard to other Valid Claims covering other aspects of such Product, including, for example, claims covering the formulation, application or synthesis of such Product); or (c) until there no longer exists a Valid Claim of Licensed Patents whose use resulted in the Product. Payments shall be made concurrently with delivery of the quarterly payment report pursuant to Section 7.4. Royalties shall be paid at the applicable marginal rate set forth above with respect to Net Sales in a particular year. Therefore, for example, if cumulative annual Net Sales of a Product marketed for *** were ***, ALTANA would pay to GPC royalties at the rate of *** of Net Sales up to $100 million ***, ***% of Net Sales above $100 million up to $250 million ***, and *** of Net Sales above $250 million up to $400 million *** for total royalties due in that year of ***.

The exchange rate will be the average rate between the buying and selling rate as quoted in the Wall Street Journal on the last business day of the reporting period.

7.2. Foreign Legal Restrictions on Payment. If at any time legal restrictions prevent the prompt remittance of part or all payments by ALTANA with respect to any country where a Product is sold, unless prohibited from lawfully doing so, ALTANA shall pay GPC directly from another source of funds for the amount impounded. ALTANA will then pay all future royalties due to the other from another source of funds so long as the legal restrictions of this section still apply.

7.3. First Commercial Sale. ALTANA also agrees to report to GPC in its immediately subsequent progress and royalty report the date of First Commercial Sale of a Product in each country.

7.4. Quarterly Payment Reports. After the First Commercial Sale of a Product anywhere in the world, ALTANA shall make quarterly payment reports to GPC on or before the first day of March, June, September and December of each year for the preceding calendar quarter. Each report shall cover the most recently completed calendar quarter and shall show (a) the gross sales and Net Sales of Products sold during the most recently completed calendar quarter; (b) the number of each type of Products sold; (c) the royalties, in U.S. dollars, payable

with respect to the sales; (d) the method used to calculate the payments owed to GPC; and (e) the exchange rates used. If no sales of Products are made during any reporting period, a statement to this effect is required.

7.5. Interest on Late Payments. ALTANA will be in default with respect to payment, without receipt of a reminder from GPC, for all payments not paid timely. In case of default with respect to payment, any amount not paid timely shall bear interest from its due date through the date of effective receipt of payment at the rate of 4% over the prime rate published in the eastern edition of The Wall Street Journal on the date such payment was due or a comparable newspaper if The Wall Street Journal shall cease publishing the prime rate.

7.6. Taxes. All prices under this Agreement (royalties and other prices) are net prices. Any payment under this Agreement shall be made plus value added tax, if value added tax is levied under applicable law. Fees of any nature levied or incurred on account of any payments from ALTANA to GPC accruing under this Agreement, by national, state or local governments, will be assumed and paid by ALTANA.

ALTANA shall have the right, exercisable during a term of three (3) months following receipt of GPC’s notification, to have GPC assign such patent or patent application to ALTANA. If ALTANA elects to exercise such right, GPC shall assign such patent or patent application to ALTANA without undue delay and ALTANA shall reimburse GPC for fifty percent (50%) of all reasonable costs actually incurred by GPC relating to the filing, prosecution and maintenance of such patents or patent applications prior to the date of such assignment.

11.4. ALTANA Intellectual Property. ALTANA shall have the right but not the obligation to prepare, file, prosecute and maintain patent applications and patents, continuations, continuations-in-part, divisions, reissues, additions, renewals, or extension thereof included in the ALTANA Intellectual Property, in countries of its choice throughout the world, for which it shall bear all costs.

licensed to GPC pursuant to Section 3.3.3, 4.2 or 15.3.3(c) in any country to which such license pertains, it shall promptly notify GPC in writing of its intention. GPC shall have the right, exercisable during a term of three (3) months following receipt of ALTANA’s notification, to have ALTANA assign the ALTANA Intellectual Property concerned to GPC. If GPC elects to exercise such right, ALTANA shall assign such ALTANA Intellectual Property to GPC without undue delay and GPC shall be obliged to reimburse ALTANA for fifty percent (50%) of all reasonable costs actually incurred by ALTANA relating to the filing, prosecution and maintenance of such patents or patent applications prior to the date of such assignment. In the event that GPC elects to notify ALTANA that it does not intend to exercise the rights granted under this Section 11.4, or that GPC does not respond to ALTANA’s notification within the time period specified hereinabove, ALTANA shall be free to abandon the ALTANA Intellectual Property concerned, with respect to the country concerned.

Any recovery or damages derived from a suit or action in which ALTANA has not joined shall be retained by GPC.

12.1.2 If after the expiration of the three (3) month period GPC has not commenced or, if commenced, is not actively pursuing, legal action against an infringer, ALTANA shall have the right, but not the obligation, to bring suit against such an infringer under the GPC Patents within the Field and join GPC as a party plaintiff; provided, however, that ALTANA shall bear all expenses of such suit. GPC shall have the right prior to commencement of the trial, suit or action taken by ALTANA, to join any such suit or action, and in such event

pay one-half the costs of such suit or action. No settlement, consent judgment or other voluntary final disposition of the suit or action may be entered into without the consent of GPC. In the event that GPC has not joined the suit or action, GPC will reasonably cooperate with ALTANA and shall have the right to consult with ALTANA and be represented by counsel, at its own expense.

Any recovery or damages derived from a suit or action in which GPC has not joined shall be retained by ALTANA; provided, however, that such recovery or damages, after reimbursement of ALTANA’s documented out of pocket legal expenses, shall be treated as Net Sales of Products.

12.2. Infringement by Third Parties of ALTANA Intellectual Property and/or Collaboration Patents.

12.2.1 If either ALTANA or GPC becomes aware of an infringement of any patent rights included within the ALTANA Intellectual Property (to the extent that GPC is a licensee of ALTANA Intellectual Property hereunder) and/or the Collaboration Patents included in the Licensed Patents, it shall give prompt notice thereof to the other Party. ALTANA shall have the right but not the obligation to obtain a discontinuance of such infringement or bring suit against the Third Party infringer within three (3) months from the date of notice. ALTANA shall bear the expenses of any suit or other legal action brought by it. GPC shall have the right prior to commencement of the trial, suit or action taken by ALTANA to join any such suit or action, and in such event shall pay one-half of the costs of such suit or action. In the event that GPC has not joined the suit or action, GPC will reasonably cooperate with ALTANA and shall have the right to consult with ALTANA and be represented by counsel, at its own expense. Any recovery or damages derived from a suit or action in which GPC has joined and shared costs shall be used first to reimburse each Party’s documented out-of-pocket legal expenses with any remainder shared equally between the Parties. Any recovery or damages derived from a suit or action in which GPC has not joined shall be retained by ALTANA; provided, however, that such recovery or damages, after reimbursement of ALTANA’s documented out of pocket legal expenses, shall be treated as Net Sales of Products.

12.2.2 If after the expiration of the three (3) month period ALTANA has not commenced or, if commenced, is not actively pursuing, legal action against an infringer, GPC shall have the right, but not the obligation, to bring suit against such an infringer under any patent rights included within the ALTANA Intellectual Property and/or the Collaboration Patents included in the Licensed Patents, and join ALTANA as a party plaintiff; provided, however, that GPC shall bear all expenses of such suit. ALTANA shall have the right, prior to commencement of the trial, suit or action taken by GPC, to join any such suit or action, and in such event pay one-half the costs of such suit or action. No settlement, consent judgment or other voluntary final disposition of the suit or action may be entered into without the consent of ALTANA. In the event that ALTANA has not joined the suit or action, ALTANA will reasonably cooperate with GPC and shall have the right to consult with GPC and be represented by counsel, at its own expense. Any recovery or damages derived from a suit or action in which ALTANA has joined and shared costs shall be used first to reimburse each Party’s documented out-of-pocket legal expenses with any remainder shared equally between the Parties. Any recovery or damages derived from a suit or action in which ALTANA has not joined shall be retained by GPC.

12.3. Infringement Actions against ALTANA. In the event that any action, suit or proceeding is brought against, or written notice or threat thereof is provided to, ALTANA alleging infringement of any patent or unauthorized use or misappropriation of technology arising out of or in connection with ALTANA’s practice of Licensed Patents (to the extent such action, suit or proceeding specifically relates to claims included in such Licensed Patents, an “Infringement Suit”) or the GPC Yeast 3-Hybrid Technology and GPC Yeast 3-Hybrid Technology Improvements, ALTANA shall have the right to defend at its own expense such action; provided, however, that ALTANA shall not settle any suit in a manner that would adversely affect GPC’s rights to its intellectual property or require the payment in settlement of any loss, claim, damage, liability or action without the prior written consent of GPC, which consent shall not be unreasonably withheld. GPC agrees to cooperate with ALTANA, at ALTANA’s expense, in connection with an Infringement Suit. In the event of an Infringement Suit, ALTANA may elect to have GPC assume, at GPC’s expense, the defense and the damages, if any, resulting from such Infringement Suit to the extent such Infringement Suit relates to GPC Patents, including without limitation royalty payments required to be made by ALTANA to any Third Party as a result of an Infringement Suit. If ALTANA desires to make the election described in the preceding sentence, it shall promptly notify GPC of the nature of the Infringement Suit and the identity of the other party to the Infringement Suit. In such event, GPC shall assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that ALTANA shall have the right to retain its own counsel, with the fees and expenses to be paid by ALTANA, if representation of ALTANA by the counsel retained by GPC would be inappropriate due to actual or potential differing interests between ALTANA and any other party represented by such counsel in such proceedings. The failure to deliver notice to GPC within a reasonable time after the commencement of any such action, if and only to the extent the delay is prejudicial to its ability to defend such action, shall relieve GPC of any liability to ALTANA under this Section. ALTANA, its employees and agents, shall cooperate fully with GPC and its legal representatives in the investigation of any action, claim or liability covered by this Section.

Collaborative Research Program

Summary

Reverse Genomics Research Program for target & drug discovery based on chemical proteomics strategies

The characterization of the interaction of small molecule compounds with cellular targets plays a pivotal role in drug discovery. To just name a few, it can accelerate the development of compounds identified in cell-based screens, help determine the specificity and potential off-target mediated side effects of compounds, and possibly lead to the discovery of novel uses of compounds in the treatment of diseases other than previously anticipated.

Proteomics-based molecular interaction technologies will be utilized in the collaborative program to support:

•

The analysis of a spectrum of *** inhibitors (as reference compounds) and their target interaction landscape as determined by 3H-technologies

•

The analysis of *** inhibitors (as reference compounds) and the use of 3H-technologies in the mapping of their target interaction profiles

•

The analysis of proprietary compounds emerging from internal ALTANA drug discovery efforts (e.g. ***, compounds derived from antimicrobial programs etc.)

•

Subsequent joint target validation

Research Program

Reverse Genomics Target & Drug Discovery

Reverse Genomics^™ is a growing field in biomedical research that incorporates a number of new genomics and proteomics technologies into the study of the mechanism of action of small molecule compounds. Key technologies in these compound mode of action studies include molecular interaction technologies that support the analysis of drug-target interactions. Technologies that allow the broad analysis of protein interactions with small molecules, should have a major impact in the design and development of a new generation of safer and more efficacious therapeutics.

GPC has implemented a powerful drug-target interaction screening platform, LeadCode, which is based in part on a modified application of GPC’s Y2H technology. This is known as Y3H. GPC Biotech’s Y3H technology is based on the use of designed bifunctional fusion drugs (ligands). One component of the bifunctional ligand represents an entity with known target binding properties (e.g. methotrexate which binds with high affinity to the target protein DHFR – other ligand-receptor combinations may be used in a similar fashion), and the other component

the compound of interest. These two components are linked by a designed linker. Interaction with a target protein (prey) results in a compound-mediated dimerization (recruitment) of two distinct target fusion proteins (e.g., DB-DHFR and prey-AD), forming a complex that bears the properties of a functional transcription factor (e.g., a complex such as: DB-DHFR x MTX-cpd x Target-AD). This transcription factor can activate specific reporter genes integrated into the yeast genome. Thus, binding of a small molecule to its target protein may be monitored via the activation of reporters that promote the growth of yeast cells (when auxotrophic markers are used).

LeadCode thus represents a chemical proteomics technology platform that can be employed in the analysis of the specificity of small molecule-target interactions, as well as large scale screening of cDNA libraries in yeast for the identification of potential novel targets of a particular small molecule compound. The latter may be used to identify novel therapeutic uses (positive effects) or mechanisms for unwanted side effects.

Technologies and Work Flow

The proposed small molecule-driven target interaction and discovery programs will utilize GPC’s integrated Y3H biology and 3H-directed small molecule synthesis chemistry technologies. This integrated Y3H platform integrates multiple technologies, including:

•

GPC’s LeadCode technology for the analysis of the interaction of small molecules and proteins in yeast model systems. Future potential developments may allow the extension of this approach to small molecule interaction screening in other systems such as the interaction analysis in mammalian cells (if so, most likely provided as updates)

•

Molecular cloning technologies for the production of cDNA libraries for use in small molecule-protein interaction screening, and the synthesis of full length cDNAs for extended pathway mapping and drug-target validation

•

3H chemistry technology for the synthesis of chimeric small molecules compatible with the transferred 3H screening systems

•

Robotics and automation technologies to support integrated work flows and the scale-up of interaction screening

•

Bioinformatics technologies to support array image analysis and integrated data analysis and visualization of small molecule-target and/or pathway interaction

The objective is to establish collaborative working groups tofacilitate the transfer and acquisistion of technologies in these different disciplines. The working groups will collaborate to enable early low throughput small molecule-protein interaction screening with defined entry points (selected compounds, see below), as reasonably possible with the allocated headcount. In the second phase, a coordinated integration of the various technologies occurs, leading to the implementation of the Y3H platform within the Center. This will enable ALTANA’s subsequent use of such technology platform in multiple drug discovery programs.

Small Molecule Discovery Programs

As outlined previously, the collaborative programs are designed to provide a rapid entry into the primary technology-training phase by utilizing validated application of the technologies in

therapeutic areas of interest to ALTANA. The following programs could potentially be pursued during the Collaboration, as reasonably possible with the limited allocated headcount.

***Program

*** represent a class of enzymes that has been pursued extensively in drug discovery programs in the pharmaceutical industry. The revelation of a previously unknown contingent of *** through the human genome sequencing efforts, promises to lead to the discovery of many more *** drug targets in the future. Furthermore, knowledge of all *** encoded by the human genome will greatly facilitate the development of more specific *** inhibitors in the future. Such developments would be greatly aided by the availability of tools for the direct analysis of the interaction of inhibitors with any one potential *** target. Thus, combining the Y3H technology and the cloning of a significant set of human *** promises to accelerate any existing or future *** discovery programs.

GPC has demonstrated that the LeadCode technology is suitable for the charaterization of the interaction of active-site *** inhibitors with their respective *** targets. These studies indicate that the Y3H system may support a broader analysis of *** inhibitors and their targets. The analysis of additional *** inhibitors in a first phase of the Center build-up, represents a suitable vehicle for teaching the technology as well as the generation of reagents and data sets (reference data sets) that can subsequently be leveraged in the analysis of proprietary *** inhibitor emerging from ALTANA’s internal drug discovery efforts.

Experimental steps in the development of such a program would include:

•

The cloning of cDNAs encoding defined sets of *** of representative subclasses of the *** gene family

•

The synthesis of chimeric small molecules (e.g. MTX- *** inhibitors) for interaction analysis. These should be derived from known *** inhibitors (as reference compounds) with “known” specificities

•

Interaction analysis of such inhibitors with cloned ***, and potentially cDNA libraries (if broader profiling of the specificity of target recognition is desired in specific cases)

•

The analysis of proprietary ALTANA *** inhibitors

It is recommended to start the analysis with a set of known *** and publicly known *** inhibitors that are of pharmaceutical interest and traditionally used in either primary and/or secondary screening assays for the characterization of the selectivity of *** inhibitors. The *** genes that have been collected at the Center are an excellent resource for this purpose.

The following reference should provide a useful guideline for the selection of ***. The Joint Steering Committee should make the final selection of chemically tractable candidates to be pursued in 3H-screening.

***	Certain information on this page has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

*** Programs (***, others..)

*** represent another area of great pharmaceutical interest. ALTANA currently has an internal *** inhibitor discovery program, and thus significant expertise and existing resources in this area. Similar to the proposed *** program, the Y3H technology could be explored in the context of the analysis of publicly known and ALTANA proprietary *** inhibitors. Successful application of the Y3H technology in this area is likely to provide important insights into the profile of ALTANA’s inhibitors, and characteristics that may distinguish them from other known*** inhibitors.

The *** program will entail the testing of known *** inhibitors (as reference compounds) with known *** for calibration of the Y3H system (e.g. are *** expressed in functional form). If successful, this would be followed by cloning of known ***, testing for their expression as AD-fusions in yeast, the further synthesis of *** chimeric compounds for 3H analysis, and the interaction analysis of *** inhibitors with *** family members and/or cDNA libraries for broader profiling of the specificity of target recognition for specific inhibitors.

The Joint Steering Committee should make the final selection of candidates to be pursued in 3H-screening.

Other Drug Discovery Programs: The LeadCode technology may also be employed in the analysis of compound-target interaction for proprietary compounds derived from internal ALTANA discovery efforts. Experimental steps involved are similar to those outlined above for the other programs.

The timing of the initiation and overlap of activities associated with the various proposed programs will be coordinated by the Joint Steering Committee.
