TWTI, for itself and for its successors, assigns, subsidiaries, parents, and other Affiliates hereby unconditionally, absolutely and completely releases ACLA, including ACLA's parents, subsidiaries and other Affiliates, and the respective officers, directors, agents, and employees of each, (each an "ACLA Released Party") from and against any and all liability, damages, claims, actions, demands, responsibility, and causes of actions (for purposes of this Section 4.1(c) "Claims") with respect to or arising out of the Development and Commercialization Agreement or the Parties' relationship with each other thereunder, which TWTI ever had or may now have against TWTI. TWTI waives any and all such Claims and its rights under California Civil Code Section 1542 with respect to any such Claims, known or unknown. Notwithstanding the foregoing, TWTI does not release or waive any Claims that TWTI ever had, may now have, or which arise in the future under any surviving Section of the Development and Commercialization Agreement as set forth in Article 2 above. For clarity, however, no breach of this Agreement by ACLA shall give rise to Claims determined based upon the Development and Commercialization Agreement. _______________ *** Certain information on this page has been omitted and filed separately with the Securities and Exchange Commission.

ACLA shall pay to TWTI an annual fixed royalty in each calendar year of the three (3) calendar years beginning in calendar year 2003 and continuing through calendar year 2005, as set forth in this Section 4.2(a) below. ACLA shall make each payment to TWTI no later than by January 15 of the applicable calendar year. ------------------------------------------------------------------- Calendar Year Annual Fixed Royalty ------------- -------------------- ------------------------------------------------------------------- 2002 No Royalty Due ------------------------------------------------------------------- 2003 *** fixed royalty ------------------------------------------------------------------- 2004 *** fixed royalty ------------------------------------------------------------------- 2005 *** fixed royalty ------------------------------------------------------------------- (b) Royalties on Net Sales to End Users. Subject to Sections 4.4 and 6.4 below, ACLA shall pay to TWTI as royalties the following percentages of Net Sales during the applicable calendar year beginning with calendar year 2006 and continuing during the remainder of the Term, as set forth in this Section 4.2(b) below: ------------------------------------------------------------------- Calendar Year Royalty Rate ------------- ------------ ------------------------------------------------------------------- 2006 and 2007 *** ------------------------------------------------------------------- 2008 and 2009 *** ------------------------------------------------------------------- 2010 and thereafter *** ------------------------------------------------------------------- For clarity, the Parties acknowledge that the royalties in this Agreement have been established for the convenience of the Parties based upon the assumption that the identified royalties will be paid on Licensed Product sold in all countries of the world, whether or not a license under the TWTI IP is required in the particular country in which the Licensed Product is manufactured, sold, or otherwise commercialized. Accordingly, a royalty shall be paid by ACLA on all Licensed Products in all countries whether or not a license is required in the particular country. Notwithstanding anything to the contrary, in the event that ACLA undergoes a change of control in any calendar year prior to January, 1 2010, the royalty rate on Net Sales under this Section 4.2(b) will be adjusted to be*** effective as of the date of such change of control, and will remain*** during the remainder of the Term; provided, however, that the effective date of the royalty rate adjustment shall not be earlier than January 1, 2006. For purposes of _________________ *** 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. 23 <PAGE> illustration,***. For purposes of this Section 4.2(b), the term "change of control" means any transaction or series of related transactions that would occasion: (i) any share exchange, re-capitalization, business combination, consolidation, merger or other transaction or series of transactions resulting in the exchange of the outstanding shares of ACLA unless the stockholders of ACLA that exist immediately prior to the closing date of such transaction (or series of related transactions) hold, after the closing date, more than fifty percent (50%) of the voting equity of the surviving entity in such transaction computed on a fully diluted basis, (ii) a sale, lease, or other transfer of all or substantially all of the assets or stock of ACLA; (iii) any tender offer or exchange offer for fifty percent (50%) or more of the outstanding voting securities of ACLA or the filing of a registration statement under the United States Securities Act of 1933 in connection therewith; or (iv) any person or group acting in concert to control ACLA (as control is defined in Section 1.3 of this Agreement) having acquired beneficial ownership or the right to acquire beneficial ownership of fifty percent (50%) or more of the outstanding voting securities of ACLA. As used in this Section 4.2(b), "person" and "group" shall have the meanings given to such terms when used in Sections 13(d) and 14(d) of the United States Securities Exchange Act of 1934. (c) Bundling. No Licensed Product shall be bundled and priced with any other product, component or service; likewise, no Probe Set or Cleavase Enzyme shall be bundled and priced with any other product, component or service other than as part of a Licensed Product, except in both situations, Probe Sets, Cleavase Enzyme or Licensed Products may be bundled (but not priced) with other products, components and/or services, provided that such Probe Sets, Cleavase Enzyme and Licensed Products are priced separately in accordance with the principles set forth in Section 4.2(e) below. (d) Royalty on all Components. For avoidance of doubt, Net Sales shall include the Net Sales from the distribution of all items distributed as part of a Licensed Product or Probe Set, including Cleavase Enzyme. ACLA acknowledges and agrees that TWTI's compensation for such Cleavase Enzyme under the Supply Agreement shall include both the Transfer Price for Cleavase Enzyme under the Supply Agreement and a royalty under Section 4.2 on Net Sales from the sale of Cleavase Enzyme, whether alone or as part of a Licensed Product. It is agreed that the Transfer Price alone, whether set now or in the future, shall not be considered complete compensation to TWTI for Cleavase Enzyme. (e) Conflicts of Interest. In a transaction, or series of separate transactions, involving the provision of License Products, Cleavase Enzyme, Probes Sets, or data describing the results of a Multiplexed Invader Application, and any other products, services, or non-cash consideration, to an entity (or affiliated entities) by any combination of ACLA Entities, payments received by any of the ACLA Entities as a result of such transaction(s) shall not be shifted, allocated, or weighted among such products (including License Products, Probe Sets, and Cleavase Enzyme), data, services, and non-cash consideration in any manner so as to reduce or disadvantage the Net Sales from the sale of License Products, Cleavase Enzymes, Probe Sets, Multiplexed Invader Application data. In the event of any failure to comply with this __________________ *** 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. 24 <PAGE> Section 4.2(e), or in the event that the Net Sales from the sale of a particular License Product, Cleavase Enzyme, Probe Set, or data is below the fair market value for such License Product, Cleavase Enzyme, Probe Set, or data, as applicable, then the Net Sales in the suspect transactions shall be deemed to be such fair market value for purposes of calculating payments owed to TWTI. 4.3 Share of Other Consideration. Subject to Section 6.4 ACLA shall pay TWTI*** of any and all Other Consideration received during each such calendar year of the Term; provided, however, that with respect to Other Consideration received prior to January 1, 2006, ACLA shall pay to TWTI*** of such Other Consideration allocated to the period after January 1, 2006 as set forth in this Section 4.3. In the event that the Other Consideration is not in the form of U.S. dollars, ACLA shall pay the fair market value of the Other Consideration to TWTI. With respect to Other Consideration received prior to January 1, 2006, the amount of such Other Consideration that shall be allocated to the period after January 1, 2006 shall be equal to: the total amount of Other Consideration received prior to January 1, 2006 multiplied by (1-X/Y), where (i) X is equal to the duration of time for which the applicable Manufacturing Distributor, Value Added Distributor, Enabled Customer, or Technology Access Partner is authorized to exercise rights pursuant to this Agreement prior to January 1, 2006 in connection with such Other Consideration; and (ii) Y is equal to the total duration of time for which such party is authorized to exercise rights pursuant to this Agreement.

If, during the Term, TWTI enters into a written agreement with any Third Party, other than an Affiliate of TWTI, in which TWTI grants a license to such Third Party, under the TWTI IP, to make, use, and sell products in the Gene Expression Field for*** under financial terms, considered as a whole and taking into account the non-cash consideration received by TWTI, that are substantially more favorable than those provided to ACLA in this Agreement and provided that the rights granted by TWTI are materially the same as set forth in this Agreement, then ACLA shall have the right to obtain such more favorable financial terms and conditions under this Agreement during the Term to the extent and for so long as those more favorable terms and conditions are made available to such Third Party. Notwithstanding the foregoing, this Section 4.5 shall not apply in connection with any litigation settlement, transfer or sale of all or substantially all of TWTI's business or assets related to this Agreement, whether by way of merger, acquisition of stock or assets, operation of the law, or otherwise and shall not apply in connection with any agreement in which TWTI grants exclusivity. No rebates, credits, or refunds shall be payable or provided by TWTI as a result of this Section 4.5. 4.6 Transfer Price Reconciliation. ACLA shall pay to TWTI a Reconciliation Amount with respect to quantities of Cleavase Enzyme (i) provided to Enabled Customers and (ii) used by ACLA, except for quantities of Cleavase Enzyme used by ACLA for activities described in Section 1.30 clause (A) and any activities for the development of Licensed Products, Probe Sets or Cleavase Enzymes hereunder. For purposes of this Section 4.6, "Reconciliation Amount" shall be equal to*** the Transfer Price for such Cleavase Enzyme. ACLA shall not distribute Cleavase Enzyme to an Enabled Customer, or use Cleavase Enzyme for the activities described in clause (ii) above except to the extent that ACLA pays the Reconciliation Amount to TWTI in accordance with this Agreement. The Reconciliation Amount payable under this Section 4.6 shall be deemed to accrue in the calendar quarter in which the Cleavase Enzyme is distributed to the Enabled Customer or so used by ACLA, as applicable. Notwithstanding the foregoing, no Reconciliation Amount shall be due with respect to quantities of Cleavase Enzyme manufactured by or under authority of ACLA pursuant to Section 2.10 of the Supply Agreement.

Confidential treatment has been requested with respect to the omitted portions. 26 <PAGE> quantities and type of Cleavase Enzyme used by ACLA for the activities for which the Reconciliation Amount is due under Section 4.6(ii) above; and (vi) the amounts that have been excluded from Net Sales as result of Section 6.4. With respect to Enabled Customers that are also End Users, ACLA shall provide documentation demonstrating to TWTI amounts to be included in Net Sales, otherwise amounts received from Enabled Customers shall be deemed Other Consideration. Concurrently with providing each such report, ACLA shall pay TWTI all amounts accruing during the period covered by such report. The Parties hereby acknowledge and agree that all reports, and all information in such reports, provided by ACLA pursuant to this Section 5.1 are Confidential Information of ACLA. 5.2 Mode of Payment. All payments made pursuant to this Agreement shall be made by check or direct wire transfer of United States Dollars in immediately available funds in the requisite amount to such bank account as TWTI may from time to time designate by written notice to ACLA; provided that all payments above One Million United States Dollars (U.S. $1,000,000) shall be made by direct wire transfer. Payments will be without reduction for any taxes (such as, without limitation, any withholding and other taxes imposed on the payee), fees or charges, to the extent applicable. In the event that sales are made or fees received in currency other than United States Dollars, payments by ACLA shall be calculated based on currency exchange rates for the last calendar quarter for which remittance is made. For each calendar quarter, such exchange rate will equal the arithmetic average of the daily exchange rates (obtained as described below) during the calendar quarter for purchase of United States Dollars by sale of such non-United States Dollar currency; each daily exchange rate will be obtained from the Reuters Daily Rate Report or The Wall Street Journal, Eastern U.S. Edition, or, if not so available, as otherwise agreed by the Parties. 5.3 Records. ACLA shall keep, and shall cause its Resellers, Value Added Distributors, and Manufacturing Distributors to keep, complete, true and accurate books of account and records sufficient to determine and establish the amounts payable under this Agreement, including without limitation to determine and establish the quantities and types of Cleavase Enzyme distributed to Enabled Customers or used by ACLA, and compliance with the other terms and conditions of this Agreement, including Sections 4.2 and 4.3 above. Such books and records shall be kept reasonably accessible for three (3) years following the end of the calendar quarter to which they pertain and shall be made available for inspection throughout such three (3) year period by an independent third party auditor selected by TWTI for such purposes in accordance with Section 5.4 below. 5.4 Audits. (a) Audit Rights; Procedure. Upon the written request of either Party (for purposes of this Section 5.4, the "Requesting Party"), and not more than once in each calendar year, the other Party (or in the case of ACLA, each of the ACLA Entities) (for purposes of this Section 5.4, the "Other Party") shall permit an independent certified public accounting firm (or other auditor in the case of audits for compliance with license restrictions) of an internationally recognized standing selected by the Requesting Party, and reasonably acceptable to the Other Party, at the Requesting Party's expense, to have access during normal business hours, and upon reasonable prior written notice, only to such of the records of the Other Party as may be reasonably necessary to, as applicable, verify the accuracy of any financial reports to the 27 <PAGE> Requesting Party with respect to the preceding three (3) years, to confirm compliance with license restrictions, or verify that the Requesting Party is receiving the most favorable terms as provided under Section 3.9(e) or 4.5 above, as applicable. For clarity, the auditor appointed by TWTI shall have the right to inspect Enabled Customer Agreements, Technology Access Partner Agreements, Reseller Agreements, Manufacturing Distributor Agreements, and Value Added Distributor Agreements to confirm compliance with license restrictions and to evaluate Other Consideration. Additionally, for clarity, the auditor appointed by either Requesting Party shall have the right to inspect all agreements relevant to confirm compliance with Section 3.9(e) or 4.5, as applicable, between the Other Party and non-Affiliate Third Parties. The accounting firm or other auditor, as applicable, will disclose to the Requesting Party whether the reports are correct or incorrect and, if incorrect, the amount by which the reports reveal any underpayment to the Requesting Party and the reason for such underpayment or whether the license restrictions have been complied with and, if the auditor believes there may be a non-compliance, all information relevant to the non-compliance. If the accounting firm or other auditor, believes the Other Party is has not complied with Section 3.9(e) or 4.5, as applicable, the auditor will so notify the Other Party in writing and the auditor will discuss the matter with the Other Party in good faith for sixty (60) days after receipt of such notice. If the auditor remains convinced that the Other Party has not complied with Section 3.9(e) or 4.5, as applicable, after such discussion, and the Other Party has not agreed to take action which the auditor agrees would remedy such noncompliance, then the auditor shall disclose to the Requesting Party the financial terms of the agreements between the Other Party and the non-Affiliate Third Parties which are material to such noncompliance. The Parties shall resolve any dispute in accordance with Section 5.4(d) below. Any and all information disclosed to the Requesting Party under this Section 5.4(a) shall be deemed Confidential Information of the Party that was being audited and no other information will be disclosed to the Requesting Party. (b) Additional Payments; Cost Reimbursement. If such accounting firm concludes that additional payments were owed to the Requesting Party by the Other Party during such period, then the Other Party shall pay the additional payments, with interest from the date originally due at an amount equal to the lesser of the prime rate plus two percent (2%), as published in The Wall Street Journal, Eastern U.S. Edition, on the last business day preceding such date, or the maximum amount permitted by applicable law, within thirty (30) days after the date the Requesting Party delivers to the Other Party such accounting firm's written report unless the additional payment is disputed by the Other Party pursuant to Section 5.4(d) below. If the amount of the underpayment for such period of at least one (1) year is greater than ten percent (10%) of the total amount owed for that year and greater than Ten Thousand United States Dollars ($10,000), then the Other Party shall, in addition, reimburse the Requesting Party for its reasonable costs related to such audit. (c) Confidentiality. The Requesting Party shall treat all information subject to review under this Section 5.4 as Confidential Information of the Other Party and in accordance with the confidentiality provisions of Article 7, and will cause its accounting firm to enter into a confidentiality agreement consistent with Article 7, obligating such firm to retain all such financial information in confidence pursuant to such confidentiality agreement. (d) Audit Disputes. If the Other Party in good faith disputes the conclusion of the accounting firm under Section 5.4(a) above that the Other Party owes additional royalties 28 <PAGE> or other payments, or any specific aspect of the conclusion, then the Other Party will inform the Requesting Party by written notice within thirty (30) days of receiving a copy of the audit containing such conclusion, specifying in detail the reasons for disputing such conclusion. Likewise, if the Other Party in good faith disputes the conclusion under Section 5.4(a) above that any particular agreement provides a non-Affiliate Third Party more favorable financial terms, or any specific aspect of the conclusion, then the Other Party will inform the Requesting Party by written notice within thirty (30) days of receiving a copy, from the Requesting Party, of the audit containing such conclusion, specifying in detail the reasons for disputing such conclusion. In either such case, the Parties shall promptly thereafter meet and negotiate in good faith a resolution to such dispute. In the event that such Parties are unable to resolve such dispute within sixty (60) days after such notice, the matter will be resolved in accordance with Section 11.8 regarding dispute resolution. 5.5 Late Payment. Any payments or portions thereof due hereunder which are not paid when due shall bear interest equal to the lesser of the prime rate as reported by the Chase Manhattan Bank, New York, New York, on the date such payment is due, plus an additional two percent (2%), or the maximum rate permitted by law, calculated on the number of days such payment is delinquent. This Section 5.5 shall in no way limit any other remedies available to either Party. ARTICLE 6 Intellectual Property 6.1 Ownership of TWTI IP and TWTI Marks. Subject to the rights granted to ACLA in this Agreement, TWTI shall own the TWTI IP and the TWTI Marks. 6.2 Patent Prosecution. (a) First Right To Prosecute. Subject to Section 6.2(b), TWTI (itself or through a designee) shall have the sole right to control the filing, prosecution and maintenance of Patents within the TWTI IP, and shall bear all costs associated therewith. TWTI shall consider comments from ACLA regarding steps that might be taken to strengthen patent protection with respect to any Patent within such TWTI IP or to expand protection in a mutually desired manner. Nothing herein shall imply or create any obligation for TWTI to file, prosecute, obtain or maintain any Patents or to follow ACLA's recommendations or comments. (b) Election Not to Prosecute or Maintain. Without limiting Section 6.2(a) above, TWTI may elect, on a country-by-country basis, not to continue to prosecute and thereby abandon an application for a Patent within the TWTI IP, or not to maintain and thereby abandon such a Patent. With respect to issued Patents only, TWTI shall notify ACLA of such election and discuss with ACLA the possibility of allowing ACLA the right to maintain, in such country or jurisdiction, such issued Patent. Nothing herein shall imply or create any obligation for TWTI to file, prosecute, obtain or maintain any Patents nor grant to ACLA any right to do so. 6.3 Patent Marking. ACLA shall mark, and cause the ACLA Entities and Technology Access Partners and Enabled Customers to mark, Licensed Products, Probe Sets and Cleavase Enzyme with the numbers of the Patents covering the same as may be necessary or 29 <PAGE> appropriate to preserve TWTI's rights under applicable law and regulations in applicable countries. In this regard, ACLA will consult with TWTI from time to time regarding such markings. 6.4 Enforcement of Intellectual Property. (a) Notice. If ACLA believes in good faith that a Third Party that is a significant competitor is engaged in sales or uses of a Competing Product (as defined below) in a given country, and that Competing Product infringes the TWTI IP in such country, then ACLA shall promptly notify TWTI in writing of such infringement, describing in such notice in reasonable detail ACLA's Corresponding Licensed Product (as defined below), the Competing Product and the Enforceable Patents (as defined below) included in the TWTI IP that ACLA believes are infringed. For purpose of this Section 6.4, (i) "Competing Product" means a product that *** (the "Corresponding Licensed Product"); (ii) "Enforceable Patent" means a Patent in such country which is included in the TWTI IP and which TWTI has the power and authority to enforce as contemplated in this Section 6.4; and (iii) the term "significant competitor" means a Third Party who *** and whose total revenues from its sales of such Competing Product in a given country that are used in such country are greater than or equal to *** of the total aggregate amount of the ACLA Entities' Net Sales and Other Consideration from sales of the Corresponding Licensed Product in such country in the most recent twelve (12) consecutive calendar month period, provided that the ACLA Entities' Net Sales and Other Consideration from the sales of the Corresponding Licensed Product that are used in such country exceeds*** during such period. (b) Right to Enforce TWTI IP. TWTI (itself or through a designee) shall have the sole right, but not the obligation, to enforce and control the enforcement of the TWTI IP. With respect to enforcement by TWTI of an Enforceable Patent in the TWTI IP against a significant competitor with respect to a Competing Product for which TWTI has received notice from ACLA in accordance with Section 6.4(a), TWTI shall keep ACLA reasonably informed on a reasonably timely basis, and reasonably consult with ACLA and consider in good faith the reasonable comments of ACLA, regarding such enforcement, both prior to and during any such enforcement. ACLA shall assist TWTI and provide information, upon request, and to the extent commercially reasonable for ACLA, in taking any action to enforce the TWTI IP. Amounts invoiced by ACLA on sales, after the occurrence of a Toll Event (as defined below), of Corresponding Licensed Product shall be excluded from Net Sales for units used in the country in which the Toll Event occurred, but only until such time as the Toll Event has been remedied in the applicable country and TWTI has so notified ACLA thereof in writing. Notwithstanding anything to the contrary, no amounts shall be excluded from Net Sales, and no Toll Event shall be considered to have occurred, if ACLA has failed to provide information or assistance reasonably requested by TWTI or if there is a difference between the Corresponding Licensed _____________ *** 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. 30 <PAGE> Product and the Competing Product that provides a reasonable basis for concluding that the Competing Product does not infringe the Enforceable Patent even if the Corresponding Licensed Product does infringe. ACLA shall provide TWTI with technical details concerning the Competing Product and Corresponding Licensed Product sufficient to enable TWTI to understand fully the two products, and their functionality and composition, and to establish infringement by the Competing Product. As used herein, a "Toll Event" shall be deemed to have occurred if ACLA has provided TWTI with notice of a Competing Product and infringement in accordance with Section 6.4(a), Competing Product used in the country identified in ACLA's notice continues to be sold by an entity that is a significant competitor in such country with respect to such Competing Product, and either of the following is true: (X) TWTI (itself or through a designee) has not, within *** days after receiving such notice from ACLA under Section 6.4(a), initiated actions to commence one of a lawsuit against, negotiations for a license with, or other reasonable enforcement of an Enforceable Patent against such entity with respect to the applicable Competing Product in the applicable country or (Y) TWTI (itself or through a designee) has not, within *** after such notice, executed with such significant competitor a license or other authorization under the infringed Enforceable Patent, and has not within such period commenced a lawsuit against such significant competitor, each with respect to the Competing Product in the applicable country. A Toll Event shall be considered remedied if any of the following occurs: TWTI has executed a license or other authorization for the Competing Product in the applicable country; TWTI has commenced a lawsuit; the entity that was a significant competitor is no longer a significant competitor in the applicable country with respect to the applicable Competing Product; TWTI no longer has the power or authority to enforce the Enforceable Patent in the applicable country against the significant competitor with respect to the Competing Product through no action of TWTI (such as without limitation as a result of expiration of the Enforceable Patent, expiration of TWTI's exclusive in-license, or otherwise); a reasonable non-infringement and/or invalidity opinion has been provided by TWTI; or ACLA has failed to provide information or assistance reasonably requested by TWTI. Nothing shall be construed to require TWTI to bring an action based upon all of the Enforceable Patents that may be infringed. (c) Defense of TWTI IP. TWTI (itself or through a designee) shall have the sole right, but not the obligation, to defend and control the defense of the TWTI IP; provided, however, that if ACLA is a party to any such action or proceeding regarding TWTI IP, ACLA shall have the right to conduct and control its defense of itself and its Licensed Products at ACLA's cost and expense, subject to Article 9. For clarity, the foregoing shall not be construed to provide ACLA with any rights to enforce or defend any TWTI IP in any manner. In such case where ACLA is a party, each Party shall keep the other informed on a reasonably timely basis, and reasonably consult with the other and consider in good faith the reasonable comments of the other, regarding such defense both prior to and during any such defense. ACLA shall assist TWTI and provide information, upon request, and to the extent commercially reasonable for ACLA, in taking any action to defend the TWTI IP. ______________ *** Certain information on this page has been omitted and filed separately with the Securities and Exchange Commission.

Such arbitrator shall have appropriate experience in the biopharmaceutical industry and be independent of all the Parties. Within thirty (30) days after such arbitrator is identified and retained in writing, each Party shall submit to such arbitrator and the other Party a written proposal for resolving such dispute. The arbitrator shall select the proposal of one Party without alteration or modification, which proposal shall be deemed the judgment and award with respect to such dispute. The arbitrator shall limit discovery as reasonably practicable to complete the arbitration as soon as practicable. (c) Judgments. An award rendered pursuant to this Section 11.8 shall be final and binding upon all parties participating in such arbitration. The arbitrator may, upon competent proof, grant any remedy or relief that the arbitrator deems just and equitable under the terms and conditions of this Agreement. Nothing in this Agreement shall be deemed as preventing any Party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the Parties and the subject matter of the dispute. Judgment upon the award may be entered in any court having jurisdiction, or application may be made to such court for judicial acceptance of the award and/or an order of enforcement as the case may be and shall be deemed to be a final determination. (d) Preliminary Injunctions. Notwithstanding anything to the contrary in this Section 11.8, a Party shall have the right to seek a temporary restraining order or preliminary injunction from any court of competent jurisdiction in order to prevent immediate and irreparable injury, loss or damage on a provisional basis, pending the decision of the arbitrator(s) on the merits under this Section 11.8. 11.9 Notices and Deliveries.

(Nasdaq: ACLA) and Third Wave Technologies Inc. (Nasdaq: TWTI) today announced that they have entered into license and supply agreements under which ACLARA will have rights to incorporate Third Wave's Invader(TM)technology and Cleavase(R)enzyme with ACLARA's eTag(TM)technology to offer the eTag Assay System for multiplexed gene expression applications for the research market. The new business relationship allows ACLARA to directly develop and commercialize its multiplexed eTag-Invader(TM) gene expression assays, greatly streamlining the operational structure of the previous collaboration and permitting ACLARA to fully exploit a large market with an unmet need. ACLARA's products enable pharmaceutical and biotechnology companies to more efficiently identify important drug targets and new medicines, and to characterize disease status and treatment. In addition to licensing the Invader technology platform to ACLARA for gene expression applications for research use, Third Wave will supply Cleavase enzyme to ACLARA for incorporation into eTag-Invader gene expression assays. "This new commercial relationship provides ACLARA with an enhanced ability to address the sizable gene expression research market," said Joseph M. Limber, ACLARA's president and chief executive officer. "We plan to aggressively develop this significant market opportunity. Researchers want an accurate, efficient alternative for analyzing tens to hundreds of genes and eTag-Invader gene expression assays are ideally suited for these types of experiments. With our new agreement with Third Wave, ACLARA has greater flexibility to efficiently commercialize these applications." <PAGE> "We believe ACLARA's eTag chemistry with our Invader(R) assay is a breakthrough detection technology for highly-multiplexed gene expression analysis," said Lance Fors, Ph.D., Third Wave chairman and chief executive officer. "The Invader(TM) platform is increasingly becoming the platform of choice and this license is one example of merging two great technologies to offer a uniquely-differentiated, value-added product." The powerful combination of eTag reporter molecules and the proven Invader technology provides superior performance for profiling the expression of many genes compared to other DNA and RNA detection methods. eTag-Invader multiplexed, quantitative gene expression analyses are highly precise, accurate and efficient, enabling researchers to obtain decision-critical results more quickly and have greater success at detecting targets and drug response. Researchers can easily perform these analyses at high throughput using far less bio-sample and can compare results across different samples, experiments and labs. They can profile many genes simultaneously in a single reaction directly from crude cell lysates, without the need for sample preparation or polymerase chain reaction (PCR) and with built-in internal controls. The agreement provides ACLARA with a license for Third Wave's Invader technology platform for multiplexed gene expression analysis in the research market. In exchange, ACLARA will make undisclosed upfront payments and will make royalty payments to Third Wave on sales of eTag-Invader gene expression assays. The agreements supercede the previously announced collaboration agreement between the two companies. About ACLARA ACLARA BioSciences, Inc. is developing advanced tools for drug discovery, genomics and proteomics using its proprietary eTag(TM) assay chemistries and microfluidics expertise. The Company's products allow researchers to have decision-critical information for drug development, which previously was difficult or impossible to obtain. The solution-phase eTag Assay System is cost-effective, easy-to-use and flexible, and enables highly accurate and precise analysis of genes and/or proteins from limited biological samples. Importantly, researchers can use their existing instrument platforms to perform eTag analyses. More information on ACLARA can be obtained on the Company's web site at www.aclara.com.
