                    (ii) If a party delivers the request to the Supervisory Board for determination, the Supervisory Board shall promptly, but not later than the later of (i) [...***...] after receipt of a requested modified Ultrio 2 Development Program, or (ii) [...***...], meet and discuss the proposed Material Modification to Ultrio 2 Development Program.

                    (iii) If the Supervisory Board has met and consulted without resolution, then either party may, in its discretion, determine that the parties have reached an impasse with respect to any proposed modification and implement the escalation procedure described in Article 13 of the Agreement to resolve such impasse. Notwithstanding anything to the contrary in this Ultrio 2 Addendum or the Agreement, all Material Modifications, whether agreed or determined through arbitration, shall be finally determined and documented in accordance with this Section 3.3. Where one party has rejected a proposed modified Ultrio 2 Development Program, the sole question to be presented in any arbitration is whether that party unreasonably withheld its approval.

          3.3.5 Effective Date of Modified Ultrio 2 Development Program. At such time as the parties (or, if applicable, the Supervisory Board) shall have accepted a modified Ultrio 2 Development Program incorporating a Material Modification, or any portion thereof, the parties shall evidence such

agreement by initialing the revised Product Requirements Document, Software Requirements Specification, Resource Plan or Budget, as applicable. The Ultrio 2 Development Program as so modified and approved shall constitute the Ultrio 2 Development Program hereunder and be incorporated by reference into this Ultrio 2 Addendum, and shall supersede the preceding Ultrio 2 Development Program, or applicable portions thereof, for all purposes. In order to evidence their agreement to the revised Ultrio 2 Development Program, the parties shall include it in an additional volume of the Binder, labeled “Amendments to Ultrio 2 Development Program,” in which all amendments and modifications to the Ultrio 2 Development Program will be kept.

     3.4 Notice of Significant Changes. Each party will give [...***...] notice to the other party prior to any proposal of a significant reduction or increase in resources from the then-current Resource Plan in order to allow the parties time to divert resources either to or from the Ultrio 2 Development Program. Any significant changes to the Budget or the Resource Plan shall be effective only upon the expiration of [...***...] from the delivery of such notice, unless the parties both agree to a shorter period of time in writing.

4. Changes to Ultrio 2 Assay Product after Completion Date.

     4.1 Process. Notwithstanding the provisions of Section 3, the parties recognize that from time to time during the term hereof the market may demand or regulatory changes may require that special enhancements or modifications be made to the Ultrio 2 Assay Product, and that either party may desire to adopt such changes. From and after the Completion Date, each party will notify the Supervisory Board promptly upon receipt of a request from a customer, or upon identification of regulatory changes that may require the parties to implement any enhancement, modification or other change to the Ultrio 2 Assay Product. The Supervisory Board shall promptly, but not later than the latter of (i) [...***...] after receipt from a party of such request for such changes to the Ultrio 2 Assay Product, or (ii) [...***...], meet and consult with respect to such requested change. The Supervisory Board shall decide (i) whether the requested changes should be implemented; and (ii) whether the requested changes can be implemented under the terms of this Ultrio 2 Addendum or are significant enough to warrant a new Development Program under the terms of Article 3 of the Agreement, in which case the parties shall use the process more particularly described in Section 3.2 of the Agreement.

     4.2 Additional Work under Addendum. If the Supervisory Board determines that the changes are sufficiently minor that they can be implemented under this Ultrio 2 Addendum, then the parties shall implement the process more particularly described in Section 3.3 above, and the Supervisory Board may approve a new Ultrio 2 Development Program, consisting of a new modified Product Requirements Document, Software Requirements Specifications, Resource Plan and Budget, for the purpose of developing such changes. Notwithstanding the foregoing, nothing herein shall obligate either party to conduct development work after the Completion Date with respect to the Ultrio 2 Assay Product, without regard to whether the other party indicates a willingness to pay some portion or the entire costs of such development.

5. Ultrio 2 Development Costs.

     5.1 [...***...] Ultrio 2 Development Costs. [...***...] Ultrio 2 Development Costs, as defined in and subject to Section 5.2 below. Such costs shall be payable as described in Section 5.3 herein. The Budget has been prepared for the purpose of permitting the parties to plan for Ultrio 2 Development Program expenditures related to Ultrio 2 Development Costs hereunder and represents the parties’ best estimate of such Ultrio 2

Development Costs, but does not represent a “fixed price maximum” or other guaranteed maximum cost of the development required for the Ultrio 2 Development Program. Marketing Evaluations are outside the scope of Development Costs [...***...], Gen-Probe will not unreasonably withhold support of Marketing Evaluations.

     5.2 Definition and Calculation of Ultrio 2 Development Costs: “Ultrio 2 Development Cost” with respect to the Ultrio 2 Development Program means the fully-burdened cost of conducting the research and development (including clinical trials and domestic and international regulatory submissions) of the Ultrio 2 Assay Product, and shall include (i) the reasonable cost of all quantities of raw materials, intermediates and finished goods necessary for the manufacture of such quantities of the Ultrio 2 Assay Product utilized during the Ultrio 2 Development Program, and (ii) the reasonable cost of such quantities of the Ultrio 2 Assay Product that are manufactured for, but not utilized during, the Ultrio 2 Development Program, that are not sold nor retained for research and/or development or other internal purpose and are scrapped due to product expiration; provided, however that internal costs and costs payable to Third Parties for clinical trials shall not be included within “Ultrio 2 Development Costs” until such internal costs and costs payable to Third Parties exceed the Duplex/eSAS Clinical Trial Costs, as set forth in Sections F.1 and F.4 of the Short Form Agreement. “Ultrio 2 Development Costs” shall include any direct costs incurred in modification of the eSAS and Tigris instruments hardware and software as required for purposes of enabling the instruments to perform the Ultrio 2 Assay Product. In the event the modified TIGRIS instrument does not meet PRD requirements for MTBF, if both parties agree to proceed with the development program then the Supervisory Board will decide how to address the burden of instrument costs attributable to the Ultrio 2 modifications. Costs will be calculated in accordance with United States generally accepted accounting principles, consistently applied (“U.S. GAAP”), or as otherwise mutually agreed in writing between the parties.

          5.2.1 Ultrio 2 Development Costs; FTE Labor Rate.

               (a) In lieu of accounting specifically for and receiving direct reimbursement for certain Ultrio 2 Development Costs, the parties have agreed to include reimbursement for those certain categories of Ultrio 2 Development Costs within an agreed-upon labor rate for full time equivalent personnel (the “FTE Labor Rate”). Those categories of “Ultrio 2 Development Costs” included within the FTE Labor Rate are those costs more particularly described on Schedule 5, in paragraph 2 entitled “Ultrio 2 Development Costs included within FTE Labor Rate”. Neither party shall be reimbursed separately for Ultrio 2 Development Costs included within FTE Labor Rate. Those categories of “Ultrio 2 Development Costs” not included within the FTE Labor Rate are those costs more particularly described on Schedule 5, in paragraph 3 entitled “Ultrio 2 Development Costs not included within FTE Labor Rate”. Each party shall be reimbursed separately for Ultrio 2 Development Costs not included within FTE Labor Rate.

               (b) The FTE Labor Rate in effect as of the Addendum Effective Date is set forth in paragraph 1 on the attached Schedule 5, and is included in the Resource Plan and reflected in the Budget. Each year the parties will evaluate and re-set a FTE Labor Rate for the Budget for the new calendar year based on the parties’ budgets for the then-current calendar year and consistent with the requirements of Section 5.2.1(d) below. In the event the parties shall not have agreed upon a new FTE Labor Rate before commencement of a calendar year, the parties shall use the rate in effect during the immediately preceding calendar year for billing purposes, subject to “true-up” (using the same methodology as described in Section 5.2.1(e) below) at such time as the FTE Labor Rate for the then-current calendar year has been agreed.

               (c) In addition to the annual reset described in Section 5.2.1(b) above, either party shall have the right to request a change in the FTE Labor Rate reflected on the attached Schedule 5 to be applied on a prospective basis under the approval process set forth in Section 3. Acceptance of such request for modification shall be governed by Section 3.3.4 of this Ultrio 2 Addendum.

               (d) In addition to the foregoing, throughout the term of this Ultrio 2 Addendum:

                         (i) each party shall have the same FTE Labor Rate applicable to it as is applied to the other party, subject to any agreed modifications; and

                         (ii) in the event either party requests a modification to the FTE Labor Rate hereunder, the modified FTE Labor Rate shall be calculated using the same methodology as that used to calculate the FTE Labor Rate in effect as of the Addendum Effective Date. The methodology used to calculate the FTE Labor Rate in effect as of the Addendum Effective Date is described on the attached Schedule 5.2.3, entitled “Ultrio 2 Development Costs Calculation Methodology”.

               (e) In the event aggregate actual Ultrio 2 Development Costs that are reimbursed through the FTE Labor Rate exceeded, or fell short of, the agreed FTE Labor Rate reflected in the Budget (as agreed to in accordance with the provisions of Section 5.2.1(b) above) for such calendar year, the parties will “true-up” such reimbursement annually in accordance with this Section 5.2.1(e). On or before [...***...] of each year during the term hereof, each Gen-Probe will calculate and deliver to Novartis an accounting of the actual expenditures made by Gen-Probe for those costs more particularly described on Schedule 5, in paragraph 2 entitled “Ultrio 2 Development Costs included within FTE Labor Rate” and compare them to the amounts reimbursed through the FTE Labor Rate in such year. Each party will have until [...***...] in which to meet and agree upon a final FTE Labor Rate for such year (the “Final FTE Labor Rate”) which more closely approximates the actual labor rate experienced by each party. If necessary Novartis will travel to Gen-Probe in order to complete the review in these timeframes. Each party shall have the same Final FTE Labor Rate applicable to it as is applied to the other party, subject to any agreed modifications. If the parties disagree on a Final FTE Labor Rate, such disagreement shall be addressed by the Supervisory Board and, if necessary, by implementation of the escalation procedure described in Article 13 of the Agreement, excluding arbitration. In the event that one party received less than the Final FTE Labor Rate, such party shall be entitled to receive from the other party an amount equal to [...***...] of the difference between the actual Ultrio 2 Development Costs included within the FTE Labor Rate and the reimbursed Ultrio 2 Development Costs included within the FTE Labor Rate; similarly, in the event that one party received more than the Final FTE Labor Rate, such party shall be required to reimburse the other party in an amount equal to [...***...] of the difference between the actual Ultrio 2 Development Costs included within the FTE Labor Rate and the reimbursed Ultrio 2 Development Costs included within the FTE Labor Rate.

               (f) Ultrio 2 Development Costs not included within the FTE Labor Rate shall be budgeted and trued-up under the same terms as the FTE Labor Rate. This includes all scrap (for example: finished goods, sub-assemblies, TIGRIS parts and ancillaries) manufactured/procured for the Ultrio 2 program but not consumed. Translation costs will be paid by Novartis and then applied to the Monthly True Up Payment per 5.3.3.

          5.2.2 Comparison with Resource Plan. The planned resources, and the associated costs, will be broken out on a monthly basis and analyzed against the Resource Plan and reflected in the Budget.

          5.2.3 Methodology. Attached hereto as Schedule 5.2.3 is a detailed methodology for the calculation of the Ultrio 2 Development Costs, including costs reimbursed through the FTE Labor rate

and significant external costs, as defined in this Section 5.2. The parties shall use such methodology for the purpose of invoicing and payment more particularly described in Section 5.3 below.

     5.3 Payment of Ultrio 2 Development Costs. In addition to the provisions of Article 7 of the Agreement, the parties agree as follows:

          5.3.1 Accrued Ultrio 2 Development Costs. Each party has already incurred, prior to the date of execution of this Ultrio 2 Addendum, certain Ultrio 2 Development Costs. To the extent that one party has paid more than its [...***...] share of the aggregate Ultrio 2 Development Costs incurred prior to and until the date of execution of this Ultrio 2 Addendum, the other party will reimburse such party for [...***...] the difference between the Ultrio 2 Development Costs paid by that party and [...***...] of the aggregate Ultrio 2 Development Costs incurred prior to and until the date of execution of this Ultrio 2 Addendum. Attached to this Ultrio 2 Addendum as Schedule 5.3.1 is a summary of the Ultrio 2 Development Costs incurred by the parties prior to the execution of this Ultrio 2 Addendum.

          5.3.2 [...***...] Budgeted Payments. Each party’s [...***...] share of Ultrio 2 Development Costs will be [...***...] in an amount equal to the amount reflected in Budget [...***...]. The Budget sets forth the parties’ anticipated expenditures and FTE Labor amounts for Ultrio 2 Development Costs [...***...] during the term of the Ultrio 2 Development Program in the line item entitled “Total Project Gen-Probe” and “Total Project Novartis,” respectively. The line items entitled “Gen-Probe Payment to Novartis” and “Novartis Payment to Gen-Probe” in the Budget identify (i) the amount by which Novartis and Gen-Probe, respectively, are anticipated to incur Ultrio 2 Development Costs in excess of their respective [...***...] share (the “negative delta”), and (ii) the party who is required to make the reimbursement payment. [...***...] during the term of the Ultrio 2 Development Program, Gen-Probe will invoice Novartis the amount of such negative delta net of any credits or additional charges against amounts previously paid that have been agreed to by the Project Management prior to the date on which Gen-Probe rendered the invoice. Attached hereto as Schedule 5.3.2 is an example of this payment methodology.

          5.3.3 [...***...] True-Up Payments. At the end of [...***...], each party will calculate the actual FTE Labor hours expended on the Ultrio 2 development Program during [...***...]. The Project Manager will review these actual FTE Labor hours compare them to the Budget for the applicable [...***...]. In the event that one party expended more than [...***...] of actual FTE Labor hours or Ultrio 2 Development Costs not included in the FTE Labor hours during [...***...], taking into account all payments made under Section 5.3.2, the parties shall calculate the cost of such negative delta using the agreed FTE Labor Rate and Gen-Probe will adjust the next invoice issued to Novartis in the amount of such credit or additional charge on or before the expiration of [...***...] after the end of the applicable [...***...]. Attached hereto as Schedule 5.3.3 is an example of this true-up methodology.

          5.3.4 Invoices. Each party will invoice the other for the amounts described in this Section 5.3 and all invoices will be due and payable [...***...] from the date of the invoice. In the event payment is not received within such period, the delinquent party shall pay a service charge if billed, equal to the amount overdue multiplied by [...***...], but not exceeding the maximum allowable rate.

     5.4 Dispute. Neither party shall unilaterally invoice the other in advance for more than the amount reflected in the then-current Budget in a given period nor withhold payments of the amount reflected in the then-current Budget. Either party may, in its discretion, determine that the parties have reached an impasse with respect to a particular Budget item, the invoicing or payment of same, and implement the escalation procedure described in Article 13 of the Agreement to resolve such impasse. Notwithstanding the foregoing, neither party may withhold payment of [...***...] budgeted payments under Section 5.3.2, cease development work or otherwise impede the progress of the Ultrio 2 Development Program by reason of such dispute.

     5.5 Right to Audit and Verify. Each party is entitled to review, evaluate, and in its discretion independently verify the basis of and actual expenditures incurred by the other party for which such party requests reimbursement as Ultrio 2 Development Costs hereunder, in accordance with the provisions of Section 7.3 of the Agreement, including without limitation actual expenditures after the Addendum Effective Date but prior to the execution of this Ultrio 2 Addendum.

6. Manufacturing and Commercialization.

          6.4.2 Section 6.10 of the Original Agreement is amended to add the following as new subsection (b), applicable to the Ultrio 2 Assay Product only:

“(b) Gen-Probe agrees to provide to Novartis reasonable quantities of the Ultrio 2 Assay Product manufactured by Gen-Probe for uses other than sale to customers, including without limitation research studies, marketing studies, internal research and development, and troubleshooting (all for Novartis’s use only in direct furtherance of the express purposes of this Agreement and without any implied license for any purpose other than such express purposes), to the extent such Products are specifically ordered by Novartis for such purposes (“Non-commercial Ultrio 2 Assay Products”). The entire compensation to Gen-Probe for Non-commercial Products shall be not greater [...***...], as determined by reference to Gen-Probe’s customary and ordinary accounting practices. The quantities of Non-commercial Ultrio 2 Assay Products ordered by Novartis as well as quantities of Ultrio 2 Assay Products consumed by Gen-Probe for all purposes other than the Ultrio 2 Assay Development Program shall be subject to review by the Supervisory Board.”

     6.5 Commercialization Budget.

               (a) For the purpose of determining “commercialization costs” (to be reimbursed to Novartis as permitted in Section 8.5 of the Agreement), Novartis shall submit to Gen-Probe a commercialization budget, promptly following any termination of this Ultrio 2 Addendum for breach in accordance with Section 8.2 or an unilateral withdrawal by a party in accordance with Section 8.4, and the timely election by a Continuing Party to continue the Ultrio 2 Development Program, as described in this Section 6.4.

               (b) Novartis shall submit to Gen-Probe a commercialization budget, setting forth the programs and anticipated costs, including applicable costs and overhead for internal sales, marketing, distribution, training, technical support, instrument service and field service engineering, product support, quality assurance, regulatory affairs and clinical affairs all as required to commercialize the Ultrio 2 Assay. Such commercialization budget shall also include out-of pocket costs associated with each such program and initiative plus costs associated with any third party support and allocated costs of instrumentation on a per unit or other reasonable allocation method applicable to the commercialization of the Ultrio 2 Assay Product. The detail and basis provided in the proposed budget shall be commensurate with the information supplied by Gen-Probe to support Gen-Probe’s calculation of Manufacturing Cost.

               (c) Gen-Probe will deliver to Novartis either a written acceptance of the proposed commercialization budget or a detailed written statement specifying the basis for rejection.

Novartis may, in response to a rejection, revise the proposed commercialization budget to reflect the discussions of the parties, and redeliver the revised commercialization budget for further review, until the parties agree upon the final commercialization budget. Either party may, in its discretion and with notice to the other party, determine that the parties have reached an impasse with respect to the proposed commercialization budget and deliver a request to the Supervisory Board for determination.

               (d) If a party delivers the request to the Supervisory Board for determination of the commercialization budget, the Supervisory Board shall promptly, but not later than the later of (i) [...***...] after receipt of the request, or (ii) [...***...], meet and discuss the proposed commercialization budget.

               (e) If the Supervisory Board has met and consulted without resolution, then either party may, in its discretion, determine that the parties have reached an impasse with respect to the proposed commercialization budget and implement the escalation procedure described in Article 13 of the Agreement to resolve such impasse.

8. Addendum Effective Date; Term; Termination.

     8.1 Term of Ultrio 2 Addendum. This Ultrio 2 Addendum shall become effective on the Addendum Effective Date and shall continue in effect through the Blood Screening Term (as determined without consideration of this Addendum), unless sooner terminated in accordance with the provisions hereof. Neither execution of this Addendum nor development and sale of the Ultrio 2 Assay Product for any market (including the United States, if agreed by the parties in accordance with Section 2.1) shall extend the Blood Screening Term as otherwise computed under Section 1.7 of the Agreement without consideration of such Ultrio 2 Assay Product, and subsection (b) of Section 1.7 shall not apply to the Ultrio 2 Assay Product. Termination of this Ultrio 2 Addendum shall be governed by the terms of this Section 8 and termination of the Agreement is governed by Section 11.2 of the Agreement.

     8.2 Termination for Breach.

          8.2.1 Default. Either party (the “nondefaulting party”) has the right, upon written notice to the other party (the “defaulting party”), to terminate the Ultrio 2 Development Program, upon

the occurrence of any of the following events of default and the expiration of any applicable period of time for cure:

               (a) if a party fails to make a payment required under Sections 5.3.2 or 5.3.3 hereunder;

               (b) if a party invoices for amounts using expenditures not falling within the definition of Ultrio 2 Development Costs or not included within the Budget.

               (c) if a party fails to exercise Commercially Reasonable Efforts to commit the resources described in the Ultrio 2 Development Program or to exercise Commercially Reasonable Efforts achieve the objectives of the Ultrio 2 Development Program; provided, however, that the failure to successfully complete the development of the Ultrio 2 Assay Product, or to complete the development of the Ultrio 2 Assay Product on the Timeline or for the amounts described in the Budget or to the specifications set forth in the PRD or the SRS shall not be deemed to be a breach of this Ultrio 2 Addendum; and

               (d) if a party defaults under the Agreement which default results in the termination of the Agreement.

          8.2.2 Right to Cure Event of Default. Upon the occurrence of any event of default entitling a party to terminate this Ultrio 2 Addendum, the non-defaulting party may send notice of event of default, specifying in reasonable detail the nature of the default, to the defaulting party. The defaulting party will have [...***...] following the date of receipt of such notice within which to cure the breach or event of default. Failure to cure the default within such time period will result in termination of the Ultrio 2 Development Program without further notice by the non-defaulting party, unless such non-defaulting party extends the cure period by written notice or withdraws the default notice. (The expiration of the period for such right to cure without cure, extension or withdrawal of the default notice is referred to as the “effective date of termination”.)

          8.2.3 Effect of Termination for Breach. Upon a termination of this Ultrio 2 Addendum for default under this Section 8.2:

               (a) Subject to the rights of the parties under Section 9.3, the Ultrio 2 Development Program shall be terminated.

               (b) The non-defaulting party’s rights under the Agreement shall remain in full force and effect unchanged.

               (d) The defaulting party’s rights under the Agreement with respect to the Ultrio 2 Assay Product shall terminate and be of no further force and effect. The defaulting party may not undertake a development substantially similar to the Ultrio 2 Development Program with any other party for a period of [...***...] from the date of termination.

               (e) The defaulting party shall pay, to the other party, in addition to any other rights or remedies available to the nondefaulting party at law or equity, promptly upon receipt of an invoice therefore, an amount equal to (i) [...***...],

(ii) [...***...], and (iii) [...***...].

     8.3 Termination by Both Parties.

          8.3.1 Vote to Terminate. The Supervisory Board, by unanimous vote, has the right, upon three (3) months written notice to both parties, to terminate the Ultrio 2 Development Program and by extension this Ultrio 2 Addendum.

          8.3.2 Effect of Notice Period on Termination by Both Parties. During the notice period as set forth in Section 8.3.1, the provisions for reimbursement of a party’s development efforts in accordance with the then-current Budget continue in force and effect, unless the party faced with reduction agrees that it can displace employees to other activities in a shorter time. The parties agree that each party shall attempt to minimize costs during the notice period. During the notice period, the parties shall continue to perform their respective obligations under the Ultrio 2 Development Program, unless otherwise agreed by the parties in writing. Upon the expiration of the notice period (and the effective date of termination under Section 8.2 or the effective date of withdrawal under Section 8.4 of the Ultrio 2 Development Program), each party shall pay, promptly upon receipt of an invoice therefor, to the other party an amount equal to (i) all Ultrio 2 Development Costs accrued to date in the terminated Ultrio 2 Development Program for which an invoice has been rendered and (ii) all Ultrio 2 Development Costs not yet invoiced but incurred in the terminated Ultrio 2 Development Program, whether or not disputed, as set forth in the approved Budget.

          8.3.3 Effect of Termination by Both Parties. Upon any termination of the Ultrio 2 Development Program under this Section 8.3, the parties shall have such rights on termination as shall be unanimously agreed by the Supervisory Board as part of the decision to terminate for convenience.

     8.4 Termination by Either Party; Unilateral Withdrawal from Ultrio 2 Development Program. Either party (referred to for convenience as the “withdrawing party”) may elect to terminate this Ultrio 2 Addendum under this Section 8.4 on the following basis without further cause:

               (a) The withdrawing party concludes in its reasonable discretion that the potential for [...***...] by any proposed change to the Ultrio 2 Development Program requested in accordance with Section 3.3 above; or

               (b) The withdrawing party receives a request for a Material Modification of the Ultrio 2 Development Program as determined in accordance with Section 3.2.1; or

               (c) The parties have failed to achieve one or more of the Interim Events.

The withdrawing party may terminate this Ultrio 2 Addendum under this Section 8.4 upon the provision to the other party (referred to for convenience as the “non-withdrawing party”) of [...***...] prior written notice, specifying in reasonable detail the basis on which the withdrawing party is unilaterally terminating this Ultrio 2 Addendum. (The notice of intent to withdraw described in this Section 8.4 is referred to for convenience as the “withdrawal notice”; and a date which is [...***...] later is referred to for convenience as the “effective date of withdrawal”).

     8.5 Continuance of Ultrio 2 Development Program following Unilateral Withdrawal or Termination.

          8.5.1 Election. Following any termination of this Ultrio 2 Addendum for breach in accordance with Section 8.2 or an unilateral withdrawal by a party in accordance with Section 8.4, the non-defaulting party (under Section 8.2) or the non-withdrawing party (under Section 8.4) (referred to for convenience as the “Continuing Party”) may elect to continue the Ultrio 2 Development Program by providing written notice to the other party on or before the effective date of termination under Section 8.2 or the effective date of withdrawal under Section 8.4.

          8.5.2 Funding and Conduct of Development.

               (a) If a Continuing Party elects pursuant to this Section 8.5 to continue funding the Ultrio 2 Development Program, such Continuing Party shall be solely responsible for the current funding of all Ultrio 2 Development Costs from and after the effective date of termination under Section 8.2 or the effective date of withdrawal under Section 8.4, subject to the right to reimbursement more particularly described below.

               (b) In addition to Section 8.5.2(a), if the Continuing Party is Novartis, Novartis shall pay Gen-Probe [...***...]. Such amount shall be payable in accordance with the provisions of Section 5.3, including without limitation monthly payment against Budget and monthly true-up payments. Novartis shall be entitled to reimbursement of such amounts paid in accordance with the provisions of Section 8.5.3 below. In the event, however, that Novartis shall elect to cease the development, marketing and sale of the Ultrio 2 Assay Product prior to the effective commercialization thereof, then Novartis shall pay Gen-Probe an additional amount equal to [...***...] of the total aggregate Ultrio 2 Development Costs (meeting the definition and calculated as described in Section 5.2) incurred by Gen-Probe from and after the effective date of termination for breach under Section 8.2 or the date of receipt from Gen-Probe of the withdrawal notice delivered pursuant to Section 8.4 of the Ultrio 2 Addendum, which additional amount the parties agree will compensate Gen-Probe for the resources committed by Gen-Probe to the Ultrio 2 Development Program which did not result in an effectively commercialized Ultrio 2 Assay Product. Novartis shall pay such additional amount promptly upon ceasing such development, as permitted under Section 3.2.1(c) of the Agreement.

               (c) In addition to Section 8.5.2(a), if the Continuing Party is Gen-Probe, in the event that Gen-Probe shall elect to cease the development, marketing and sale of the Ultrio 2 Assay Product prior to the effective commercialization thereof, then Gen-Probe shall pay Novartis an additional amount equal to [...***...] of the total aggregate commercialization costs incurred by Novartis as approved in the commercialization budget under Section 6.4 to be incurred prior to the effective commercialization of the Ultrio 2 Assay Product. Gen-Probe shall pay such additional amount promptly upon ceasing such development, as permitted under Section 3.2.1(c) of the Agreement.

     8.5.3 Reimbursement of Development Costs. The party electing to continue development under the terms of Section 8.5 shall be deemed to be the party who “wishes to develop the Future Blood Screening Assay” described in Section 3.2.1(c) of the Agreement. The provisions of Section 3.2.1(c) and the provisions of Section 3.2.3(b)(i) of the Agreement shall govern the rights and obligations of the parties from and after the effective date of termination under Section 8.2 or the

effective date of withdrawal under Section 8.4 of the Ultrio 2 Development Program as a joint development program under this Ultrio 2 Addendum, except Section 3.2.1(b) of the Agreement shall be deleted in its entirety, and replaced with the following.

     “b. In the case of a Future Blood Screening Product which is funded by one party pursuant to Section 3.2.1(c) of the Agreement and Section 8.5 of the Ultrio 2 Addendum, such party shall be solely responsible for all Development Costs of such Future Blood Screening Assay and be entitled to reimbursement of the portion of the total Development Costs incurred after the effective date of termination under Section 8.2 or the effective date of withdrawal under Section 8.4, as the case may be (the “Post-Withdrawal Development Costs”), as follows:

     i. If the funding party is Gen-Probe, Novartis shall (A) [...***...]; (B) [...***...]; (C) [...***...]; (D) [...***...]; and (F) [...***...]. Thereafter, Net Sales shall be paid as provided under Section 3.2.7 of the Agreement.

However the parties explicitly acknowledge that in the event of the need for an urgent decision the party with primary responsibility will proceed to make the decision, and implement. It is agreed that the party with primary responsibility will make all reasonable and timely efforts to inform the other party of the issue requiring decision, particularly where the issue is one of some consequence.

     9.2 Remedies in Event of Default. Neither party shall be entitled to exercise any remedy otherwise available to it at law or in equity unless and until such party shall have provided the other party with notice of such event of default, reasonably specifying the nature of the default, and any applicable period of time for cure thereof shall have expired without cure, and the procedures defined in Article 13 of the Agreement shall have been first exhausted.

     9.3 Survival. Upon a termination of this Ultrio 2 Addendum, the following provisions of this Ultrio 2 Addendum shall survive such termination: Sections 2.3, 2.4.1, 8, 9, and 10 and all rights under Section 5.3.3 that have accrued as of the date of termination.

10. No Other Amendment. Except as expressly set forth in this Ultrio 2 Addendum, all other terms and conditions of the Agreement, the parties’ Definitive Written Settlement Agreement, dated December 5, 2001, and the Short Form Agreement, dated November 16, 2001, are hereby ratified and shall continue in full force and effect. In the event of a conflict between the terms of this Ultrio 2 Addendum and the Agreement, the terms of this Ultrio 2 Addendum shall control. The provisions of this Ultrio 2 Addendum are intended to, and hereby, supersede any provisions in the Definitive Written Settlement Agreement entered into by and between the parties, dated December 5, 2001, and the Short Form Agreement entered into by and between the parties, dated November 16, 2001, on the same subject matter.

11. Counterparts. This Ultrio 2 Addendum may be executed in counterparts, each of such shall be deemed an original, and all of which together shall constitute one and same instrument.

     IN WITNESS WHEREOF, the parties have caused this Ultrio 2 Addendum to be executed and the persons signing below warrant that they are duly authorized to sign for and on behalf of the respective parties.

Description of Ultrio 2 Assay Product

The Ultrio 2 triplex assay is an in-vitro nucleic acid amplification test for the qualitative detection of human immunodeficiency virus Type 1 (HIV-1) RNA, hepatitis B virus (HBV) DNA, and/or hepatitis C virus (HCV) RNA in human plasma for use in the Blood Screening Field. The Ultrio 2 triplex assay will not discriminate between HIV-1, HBV and HCV infection. The Ultrio 2 assay is to be developed to run initially on both the enhanced semi-automated instrument (eSAS) and the Tigris instrument.

HIV-1, HBV and HCV discriminatory Probe reagents are in -vitro nucleic acid amplification tests for the qualitative detection of the specified virus and are provided with the Ultrio 2 triplex assay as part of the Ultrio 2 Assay Product for use in discriminating between HIV-1, HBV and HCV in plasma following a positive result from the Ultrio 2 triplex assay.

For purposes of the foregoing Addendum, all of the Ultrio 2 triplex assay and the associated discriminatory probe reagents are included within the definition of the “Ultrio 2 Assay Product.”

Schedule 5.3.1

Accrued Ultrio 2 Development Costs

The parties acknowledge and agree that development costs for the calendar years 2006 and 2007 have previously been trued-up between the parties and that no payment is due from either party to the other in connection with the development program conducted during those years not withstanding both parties right to audit and verify pursuant to Section 5.5.

The parties further acknowledge and agree that they will meet and negotiate in good faith with respect to development costs incurred during calendar year 2008 prior to execution of the foregoing agreement and any payment due from one party to the other pursuant to Section 5.3.1 shall be made promptly.

Schedule 5.3.2

[...***...] Budgeted Payments

     The party with the negative delta shall submit to the other party, on or before the end of the [...***...] during the term of the Ultrio 2 Development Program, an invoice setting forth the amount of the delta. In addition, any party owed by other an excess adjustment shall submit to the other party, on or before the end of the [...***...] during the term of the Ultrio 2 Development Program, an invoice setting forth the amount of the excess adjustment, providing reasonable detail for any Ultrio 2 Development Costs not previously invoiced and requesting payment of [...***...] of the total amount. Ultrio 2 Development Costs by the invoicing party incurred to date and not yet reimbursed as provided herein, providing reasonable detail for any Ultrio 2 Development Costs not previously invoiced and requesting payment of 50% of the total amount. Each party shall pay on or before the date specified therefore in the invoice an amount equal to the lesser of (i) the Ultrio 2 Development Costs reflected on the invoice submitted to such party on account of such payment (together with amounts reflected on earlier invoices not previously reimbursed) or (ii) the amount of the payment described on the attached budget. To the extent that a reimbursement payment is inadequate to cover the total Ultrio 2 Development Costs incurred to date by a party, then each party shall carry over the balance to the next subsequent payment(s) until finally reimbursed in full.
