10.1 This Agreement shall commence as of the Effective Date and, unless sooner terminated as provided herein, shall continue in effect for the later (*) or for so long as (*); provided that if the Agreement continues for longer (*) after the Effective Date, the licenses granted to BASF under Section 3.1 shall, (*) of the Effective Date, (*).

10.2 (a) Failure of BASF or Dyadic to comply with any of their respective material obligations contained in this Agreement which constitutes a material breach shall entitle the other Party to give the Party a default notice requiring it to cure such default. If such default is not cured (*) after receipt of such notice, the notifying Party shall be entitled (without prejudice to any of its other rights conferred on it by this Agreement) (*). Notwithstanding the foregoing, in the event of a non-monetary default, if the default is not reasonably capable of being cured within the (*) cure period by the defaulting Party and such defaulting Party is making a good faith effort to cure such default, the notifying Party may (*), provided however, that the notifying Party may (*) of such original notice of default. The right of either Party (*) Agreement as herein above provided shall not be affected in any way by its waiver of, or failure to take action with respect to any previous default.

(b) In the event that one of the Parties hereto shall be insolvent, go into liquidation, a receiver or a trustee be appointed for the property or estate of that Party and said receiver or trustee is not removed (*), or the Party makes an assignment for the benefit of creditors, and whether any of the aforesaid bankruptcy events be the outcome of the voluntary act of that Party, or otherwise, (*).

(c) Except where expressly provided for otherwise in this Agreement, termination or expiration of this Agreement shall not relieve the Parties hereto of any liability accrued hereunder prior to the effective date of such termination or expiration, nor preclude either Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement nor prejudice any Party's right to obtain performance of any obligation.

Introduction.

BASF would like to further evaluate Dyadic's Myceliophthora thermophila (C l )-based gene expression platform . To this end a (*) gene will be cloned and over expressed in Cl , which should lead to the over-production of the corresponding gene product. The aim of this project is to investigate high level functional expression of (*) C1. BASF has indicated that depending on the cost of fermentation the business target for the longer term ((*)) is a production level of (*). A first short term goal (Milestone 1) (*). BASF considers this as an important proof of performance of the C I -expression system. This proposal describes in detail the activities that should lead to this first important goal within (*) (Phase 1). Depending on the level of success, a detailed strategy to reach (*) (Milestone 2) in one of the strains (*) (Milestone 3, (*)) will be developed to enhance the success rate four types of strains will be initially used in this project:

a Cl – (*).

a Cl – (*)

a C 1 – (*).

the (*), which produces (*) and it has been shown to be able to also produce other (*) proteins at (*) amounts.

The best performing (*) producing strains will then serve as the basis for further productivity optimization in a follow-up project (an outline is given at the end of this document).

Stage 1. Construction of first generation (*) producing Cl strains.

Task 1.1. Generation of (*) expression vectors for C1-strains.

(*) promoter based expression constructs will be used in the (*) strains respectively. Synthetic genes encoding (*) optimized for cloning and expression in Cl will be generated at (*) based on the sequence info by BASF and DNL. The efficient signal peptide of the Cl (*) enzyme will be engineered in front of the (*) in order to achieve efficient secretion into the growth medium. The (*) signal peptide will be removed. The (*), which remain attached to the (*) after processing. Its (*) would therefore start with (*). Since the mature (*) already starts with an (*), it would have (*) after processing. The proposed procedure is acceptable for BASF. In the meantime and as an alternative, we will evaluate the (*) for its suitability for efficient secretion in Cl .

Deliverables:

(*).

Task 1.2. Generation of first generation (*) over-producing Cl transformants.

The (*) host strains will be transformed with the respective (*) will be used as selection markers. An (*) screening assay will be set up using (*) as a substrate. Transformants will be (*). About (*) transformants per host will be screened this way. A selection of up to (*) best transformants per host will be assayed again using a micro titer-plate based (*) in order to select the best (*) transformants per host, which will then be evaluated in fermentations.

Deliverables:

(*)

Task 1.3. Fermentation of selected (*) and characterization.

The selected (*) will be fermented in order to produce as much as possible active (*). A representative working bank of fermentation inoculums vials will be generated of each strain. Fermentations will be carried out at lab scale. The target is to produce (*) and will be determined by the protocol described in Attachment D Filtrated samples (cell free) will be sent to BASF for evaluation at their laboratories.

Deliverables:

(*).

Productivity analysis.

Shipping of filtrated fermentation samples to BASF.

(*).

Task 1.4. Generation of a (*) driven (*) expression vector.

Previous research at DNL has shown strong induction of (*) production upon cultivation of C1 on soluble (*). Also strong induction of a protein upon (*) induction was observed ((*)). Expression of these genes, (*), behaves according to a (partly) different regulatory system, which could make the use of their promoters suitable in cases (*).

Confidential Information Dyadic Nederland BV

Furthermore, the (*) system might be better suited to express target genes at a moment when the (*). We therefore believe that (*) are of special interest for high level gene expression. Therefore, in parallel to the construction of (*) strains using the (*) based vectors, also a (*) route will be employed. To this end, (*) promoters will first be tested in a fermentation using the appropriate inducers. The most suitable one, (*) , will be used for construction of a (*) vector using the synthetic gene described in task 1.1.

Deliverables:

Testing the (*) expression in a labscale fermentation

(*) expression vector

Task 1.5. Determination of specific activity Cl produced (*).

Fermentation broth of task 1.3 will be used for purification of the (*). The purity level should be (*). The volumetric productivity (U/ml) will be determined using the same assay as in task 1.3. As DNL has (*) content determination based on released amino acids by HPLC after total protein hydrolysis, we propose to use our (*) protein quantification method ((*)). The determination of the specific activity of the (*) is the sole purpose of this purification effort; no pure (*) protein in any (*) is set as a deliverable. It is furthermore assumed that the (*) produced by all (*) hosts bares the same properties. Further discussion with BASF about (*) purification is needed.

Deliverables:

Purification (*)

Specific activity (*).

GO/NO GO decision point.

If a (*) productivity of at (*) is observed in Stage 1 then the project could automatically move to Stage 2. Ifless is observed a discussion between BASF and DNL should take place to determine whether we should proceed or not. BASF finally decides.

Stage 2. Construction of second generation (*) Cl strains.

Task 2.1. Generation of second generation (*) Cl transformants.

The best (*) producing (*) type transformants will be selected for further strain development. Since these strains no longer contain an (*) for genetic transformation, we propose to use the (*) in the re-transformation of the strains.

This (*) encodes an (*) and allows the transformed strain to use (*). Remaining the (*) in the final strains is not an option for BASF. Instead of the geration of a new (*), BASF requires the deletion of the (*).

These (*) strains will be transformed with the expression cassettes given in task 1.1 and 2.1 using (*) as selection marker. The screening of transformants will be similar to the approach described in task 1.2. After screening, (*) performing transformants per host will be selected for fermentations.

Deliverables:

Transformation of (*) Stage 1 transformants ((*)).

1 st Screening of (*) transformants for (*) production by (*).

2nd Screening of selected (*) transformants by micro-titer-plate based (*) assay.

Selection of (*) most promising transformants per host for fermentation.

Task 2.2. Genetic analysis of obtained transformants

The selected (*) will initially be subjected to Southern analysis in order to check for the (*). The exact genetic composition of the best (*) (determined in task 2.4) will be determined by (*), if requested by BASF and mutually agreed between the Parties. (*). It will confirm the (*) strains and it will determine (*), which is relevant for commercial product registration.

Deliverables:

(*) gene copy number determination in best (*) strain by (*) and (*) of best (*) strain. This involves (*) transformants.

(*) of (*) host strains.

Determination of (*).

Task 2.3. Labscale fermentation of selected (*) transformants and characterization.

Two fermentation runs are expected to be required to determine the proper feeding regimes for proper induction. The target is to produce (*) and will be determined by the protocol described in Attachment D. Filtrated samples ((*)) will be sent to BASF for evaluation at their laboratories.

Task 2.4 Fermentation optimization.

Task 2.3 will reveal the best producing (*) strain per set of (*). These (*) strains will subsequently be selected for fermentation optimization. The effect of culture temperature on (*) production will be evaluated at (*). Since standard (*) strain fermentations (*) ((*)), the performance of the (*) transformants will be examined using (*). Previous work at DNL has shown these compounds to be good alternatives in C1 strain fermentation. After the optimal temperature and medium composition have been determined, the relationship ("(*)" )between (*) will be determined throughout the entire fermentation process. This will then show which growth rates (feeding regime) should be applied to get the best (*) production. All these experimental fermentations will be conducted ((*))(*).

Deliverables:

Evaluation fermentation temperature ((*)). Evaluation (*) transformants.

Determination (*) and design new fem1entation process.

Verify new fermentation process.

Milestone 1 decision point

If a productivity of (*) is observed in Phase 1 the project will automatically move to Phase 2 with the objective of achieving a productivity of (*) in one of the aforementioned production strains (Milestone 2). If the productivity is less than (*) BASF and DNL should discuss the results and the potential to reach Milestone 2 and 3. Based on this discussion BASF should decide whether the project should be continued.

Phase 2.

Milestone 2: Further improvement of the (*) productivity by Cl towards (*)

(Outline).

For the Phase 2 project there are a number of possibilities for further strain and fermentation optimization:

•

(*). (*) assay allows for screening of many (*) mutants, which enhances the success rate of picking up hyperproducers.

•

Another round of transformation, using the same expression cassettes or other (different expression (*)).

•

Fermentation optimization tailored to the strains obtained.

A meaningful detailed Phase 2 project proposal can be made after the genetic and physiologic characteristics of the obtained transformants in Phase I are known.

Phase 3.

Milestone 3: Achievement of productivity of (*) of a (*) in one of the aforementioned production strains.

The approach to increase the productivity from (*) will be chosen based on the results obtained in phase 1 and 2 of the project.

Protocol for Measuring Productivity

Productivity:

The productivity is measured as mass of target protein per volume (in g/I) of total fermentation broth including biomass.

Measurement:

Dilute total fermentation broth (*)

Separate supernatant from diluted total broth

Measure volumetric activity (in U/L) of target enzyme in diluted, cell free supernatant with an activity assay used for release analytics in production or an assay mutually agreed between the Parties.

Calculate the volumetric activity of total broth including (*)

Determine the productivity in g/I by dividing the volumetric activity by the specific activity of the target enzyme

Determination of specific activity

Purify the target protein produced with the final production strain and process to a (*)

Measure the volumetric activity of the purified enzyme with the same assay as used in step 3.

For determination of the protein content of the enzyme solution of step 7 total protein hydrolysis and quantification of the released amino acids (*)

The specific activity (in U/g) is calculated from the volumetric activity measured in step 7 and the protein concentration measured in step 8.
