WHEREAS Calypte is the exclusive worldwide licensee of New York University to the patents (the NYU Patents") listed in Appendix 1 attached hereto and incorporated herein by reference relating to detecting HIV antibodies in urine; WHEREAS Calypte has developed a microtiter plate EIA (the "Screening Test") for detection of HIV-1 antibodies in urine using the NYU patents and Calypte's own technology (the "Calypte Technology"); WHEREAS Calypte has filed a Product License Application with the United States Food and Drug Administration ("FDA") for the Screening Test and believes it is in the final stages of FDA review; WHEREAS Cambridge manufactures an HIV-1 Western blot assay licensed by the FDA to confirm the results of HIV antibody detection assays using serum and plasma samples (the "Serum Blot"); WHEREAS Calypte and Cambridge propose by this agreement to develop a protocol and reagents to use or modify the Serum Blot to confirm the results of the Screening Test using urine samples (the "Urine Confirmation System"), and to seek FDA licensure or marketing approval thereof; and WHEREAS Calypte and Cambridge propose by this agreement to assign rights and responsibilities for the commercialization of the resulting product; NOW THEREFORE, and in consideration of the mutual covenants and undertakings set forth herein, the parties agree as follows: -1- 2 1 KIT CONFIGURATION Calypte and Cambridge will agree on the optimal Urine Confirmation System, taking into account manufacturing and QC efficiencies, regulatory requirements, marketing advantages, and other relevant criteria. 1.1 Preferred Kit Configuration Based on information presently available, the parties agree that the preferred Urine Confirmation System (the "Preferred Kit Configuration") consists of (i) a kit (the "Urine Control Kit") consisting of a urine sample panel containing three of each of high positive, low positive and negative controls and a package insert describing the composition of such controls, and referencing their use with the Serum Blot, and (ii) the Serum Blot with a claim permitting use of urine samples, interpretive criteria that the appearance of only a gp160 band is sufficient to declare a positive, and lot release criteria for urine consisting of testing at the kit level of a representative number of kits per lot. The parties plan to seek marketing approval for the Urine Control Kit from the United States Food and Drug Administration ("FDA") pursuant to an application under Section 510(k) of the Food, Drug and Cosmetic Act, and to seek FDA approval of the urine claim for the Serum Blot under Cambridge's existing Serum Blot product license. The Urine Control Kit would be manufactured by or on behalf of Calypte and distributed as set forth in this Agreement. The Serum Blot would continue to BE manufactured by Cambridge, and Calypte would have distribution rights as set forth in this Agreement. 1.2 Alternate Kit Configurations The parties recognize that alternative kit configurations may include modifications of the Serum Blot in which urine controls are substituted for or included in addition to serum controls, with resulting package insert changes; such configurations are anticipated to require an amendment to the Serum Blot product license, and are referred to herein as the "Urine Blot." The Urine Blot would continue to be manufactured by Cambridge, and Calypte would have distribution rights as set forth in this Agreement. Calypte agrees to reimburse Cambridge for the one-time artwork and/or design costs associated with modifying Cambridge's package insert and/or packaging if the Urine Blot is selected as the Urine Confirmation System. 2 PRODUCT DEVELOPMENT Calypte is responsible for and has commenced development of the Urine Confirmation System. - 2 - 3 2.1 Development Kits Cambridge has furnished Calypte free of charge twenty-four (24) Serum Blot kits for use in carrying out the development plan, and Calypte intends to purchase approximately twenty-eight (28) additional kits (including kits purchased to date) at a price of per kit. Cambridge will endeavor to supply the foregoing kits from three or four different manufacturing lots. In the event the FDA requires the conduct of clinical trials necessitating the use of substantially more Serum Blots, Cambridge will supply the additional Serum Blots at a cost of per kit. 2.2 Development Effort Calypte will, at its expense, prepare any necessary urine controls and other reagents necessary to enable the Serum Blot to use urine samples and to complete development of the Urine Confirmation System, and shall provide Cambridge free of charge with sufficient Urine Control Kits to enable Cambridge to validate its lot release protocol. 2.3 Draft Report Calypte will prepare a draft report, in a form agreeable to Cambridge, suitable for submission to the FDA in support of proposed regulatory submissions. 2.4 Clinical Trials Calypte will at its expense carry out all clinical trials required for regulatory approval of the Urine Confirmation System. 2.5 Cambridge obligations Cambridge will make its regulatory and product development personnel reasonably available to Calypte for consultation regarding development of the Urine Confirmation System. Calypte shall reimburse Cambridge only for reasonable out-of-pocket costs approved in advance. 2.6 Review of Data Calypte shall make available to Cambridge regulatory and product development personnel ALL relevant pre- clinical, clinical and other evaluation data regarding the Screening Test and the Urine Confirmation System, and all relevant information relating to the manufacture and validation of the Urine Control Kit. 3 U.S. REGULATORY PLAN Calypte and Cambridge have agreed on a regulatory plan for obtaining FDA approval and/or licensure of .the Urine Confirmation System, including clinical trial design and regulatory strategy. 3.1 Preferred Kit Configuration On June 9, 1995, the FDA indicated verbally that the parties may proceed with Confidential portion has been omitted and filed separately with the Commission - 3 - 4 the Preferred Kit Configuration. Accordingly, the parties have proceeded with the Preferred Kit Configuration, and the following provisions apply: 3.1.1 The current regulatory strategy is set forth in Appendix 2, a letter dated May 3, 1995 from Cindy Green of Calypte to Jay Epstein of the FDA. 3.1.2 Calypte has at its expense prepared and filed on its behalf an application for 510(k) approval. 3.1.3 Cambridge has at its expense prepared and filed a supplement to its Serum Blot product license to permit use of urine samples.

Epstein, M.D. Food and Drug Administration Center for Biologics Evaluation and Research Document Control Center Office of Blood Research and Review Division of Blood Applications (HFM-30) Woodmont Office Center, Suite 20ON 1401 Rockville Pike Rockville, MD 20852-1448 RE: PLA Reference Number 92-0670 Dear Dr. Epstein, In response to a request from Mr. Howard Balick, I am submitting an application strategy and proposal for an HIV-1 confirmatory product to the Document Center as an official request for consideration. Over the past several months, I have had phone conversations with both Mr. Balick and Dr. Gary Riordan regarding Calypte's plan to proceed with the submission of a HIV-1 confirmatory test using urine as a sample in support of the Calypte HIV-1 Urine EIA test kit currently under review. On March 6, 1995, a faxed letter was sent to Dr. Riordan to document the strategy for this application. In this letter, we requested a meeting with the reviewing committee, Calypte Biomed1cal and Cambridge Biotech (our partner for the confirmatory test) to review our preliminary data, the clinical plan and regulatory strategy. Background Information Calypte submitted the PLA/ELA for the HIVA Urine EIA test kit In September, 1992. In November, 1993, Calypte was notified of the need to aggressively pursue a confirmatory test to support the HIV-1 Urine EIA approval. Calypte contacted all licensed manufacturers (and a number of unlicensed manufacturers) of HIV confirmatory tests. After several lengthy and unsuccessful attempts to come to terms with one of the manufacturers, a business agreement was finally reached in March, 1995, with Cambridge Biotech 1 14 to bring a urine based confirmatory product to market Cambridge Biotech has had a licensed serum based HIV confirmatory test on the U.S. market since January, 1991. The proposed urine confirmatory test will be performed using the currently licensed Cambridge HIV Western Blot test kit There will be no changes to the assay components. The urine test samples will be substituted for the plasma/serum samples. The interpretation will be based on the reactivity of the serum controls currently included in the Cambridge kit. They will be run diluted with diluent provided in the kit using incubations which have been extended to accommodate the reduced titre. Laboratories wishing to confirm reactive ELISA urine samples will run the currently licensed Western blot and its serum controls In conjunction with an accessory HIV-1 Urine Control Kit In the accessory kit, there will be three levels: a negative, low positive and high positive. The urine controls will be heat inactivated and preserved with 0.1% azide. The Reactivity of the samples will be compared to the diluted low positive serum control with respect to the band intensity. A positive sample will require a band at 160kd of equal or greater intensity to the p24 band on the Reactive Control Strip using the diluted serum control material supplied in the Cambridge kit If the 160kd band is of lesser intensity than the p24 band or if there are other bands not meeting the criteria for positive, but visible, the interpretation will be indeterminate. If there are no bands, the sample Interpretation will be negative. There are other examples where the kit control material is dissimilar from the specimens being tested. In the area of HIV testing, the most noteworthy is the dried blood spot. It is our understanding that this example (dissimilar controls and specimens) has been approved for use by several manufacturers and furthermore, that there are several other examples of dissimilar controls/specimens under review by CBER. One purpose of kit controls is to demonstrate assay validity. The serum controls have been shown to be effective in accomplishing this, as shown during the four years which the Cambridge kit has been on the market. The other purpose of the kit controls is to provide a "calibrated" visual reference to determine positivity. Following dilution, this can also be accomplished with the Cambridge controls provided for the urine assay. The current instructions allow the user to visually compare the p24 band intensity to ANY of the other bands observed on the test sample. This visual comparison can be equally successful comparing the urine bands to this p24 band of the diluted Cambridge control. The Calypte HIV-1 Urine Control Kit can provide the user with the added security of running controls with the same specimen-type and will assist the laboratory in meeting CUA requirements. 2 15 In the event there are concerns regarding the lot release testing or CBER's control of the test kit for urines, we feel these concerns can be satisfied by the standard lot release testing currently performed on the Cambridge kit. The serum controls will be tested and released according to the standard procedure. Currently there are several control kits for HIV and Hepatitis which have been approved by the 510(K) approval process. We would not expect that replacing urine for serum/plasma would make this approval any different than those previously cleared. The Urine Control kit would include the urine control materials along with Instructions for running the patient samples (urine) and controls (serum) with the Cambridge Western Blot kit Therefore, the controls would be intended for use only with this specific kit. The instructions would Include interpretation criteria specific for urine reactivity. The criterion we are intending to use is a reactive 160kd band with intensity equal to or greater than the p24 band on the diluted low positive Cambridge serum control. This criterion is the same (160kd reactive band) as was used in both sets of clinical studies conducted by Calypte where the Western blots run on urine were a modified procedure using the BioRad Western Blot assay. In support of the urine application to the Cambridge Western blot, Cambridge would submit a labeling transmittal form with the change in intended use such that urine would be added as an alternative sample to serum/plasma. The Instructions would direct the user to use the Urine Control lot in conjunction with the kit serum controls provided in the currently licensed Cambridge kit. Clinical Study Plan The clinical study plan includes the evaluation of a total of 600 patient samples collected under the IND filed for the Calypte "extended study". These samples have been well characterized by urine. ETA, urine Western blot (BloRad assay modified for use with urine), and paired serum ETA and Western blot The samples chosen are distributed as follows: 200 normal, low risk 200 moderate or unknown risk 100 high risk, positive 100 special disease state (10 from each of 1O categories) liver disease, kidney disease, autoimmune disorders, IVDA, etc. 5 individual samples from seropositive individuals run in a dilutional series We feel It is appropriate to run this study in-house (using Calypte personnel since the consistency of performance of both the Cambridge Western blot as well as the modified BioRad urine Western blot procedures have been well 3 16 documented in the clinical trial data submitted by both Calypte and/or the blot manufacturers as well as FDA 's own release testing. The questions posed by the Calypte modified procedure should not require challenging the assay by evaluating site to site, operator to operator, lot to lot, or other parameters since these questions have already been satisfactorily addressed. Likewise, the more fundamental questions of whether or not there are antibodies in urine or how the antibodies react in a Western blot assay have been demonstrated in the numerous data submitted with both of Calypte's clinical trials. The samples chosen for testing are based on those populations which we assume are of greatest concern to the reviewers and those samples which may have potential problems in a urine based assay. In summary, the clinical trial strategy Is based on an application validation, since from Calypte's point of view the sample matrix change is a minor one. We are most anxious to resolve this issue and begin the studies. Since the proposed study is a retrospective one with samples collected under an IND, we are requesting a waiver for the filing of an IND and associated 30 day waiting period. Please let us know if there are suggested changes to the study plan and or submission strategy so that we can begin these critically important studies. With the plan described herein, we feel confident that the studies could be completed rapidly, the data assembled, and the submission filed with coincident approval with the HIV-1 Urine EIA. Since the submission is an application only and very minor in comparison to a standard PLA, we would except to have a review and approval within a 90 day period, if not before. As you know, it would be extremely beneficial to have both tests approved together. In past discussions, it has been indicated to Calypte that the requirement for the Urine EIA approval is contingent ONLY on the demonstration of clinical data for use an urine in a confirmatory assay with a commitment to aggressively move toward approval of this chosen confirmatory test. We have been told clearly that the approval of the confirmatory test is NOT a requirement for the HIV-1 Urine EIA approval. Therefore, although our clear preference is for simultaneous approval of both the EIA and the confirmatory assay, we do not want approval of the confirmatory assay to in any way delay the approval of the EIA. Please confirm with us that this is still the case. We thank you in advance for your prompt reply to this request and your careful consideration of the proposal described.
